Anatomic guided ablation of the atrial right ganglionated plexi is enough for cardiac autonomic modulation in patients with significant bradyarrhythmias

IntroductionCardiac autonomic system modulation by endocardial ablation targeting atrial ganglionated plexi (GP) is an alternative strategy in selected patients with severe functional bradyarrhythmias, although no consensus exists on the best ablation strategy. The aim of this study was to evaluate if a simplified approach by a purely anatomical guided ablation of just the atrial right GP is enough for the treatment of these patients.MethodsWe prospectively enrolled patients with significant functional bradyarrhythmias and performed endocardial ablation purely guided by 3D electroanatomic mapping directed at the atrial right GP and accessed parameters of parasympathetic modulation and recurrence of bradyarrhythmias.ResultsThirteen patients enrolled (76.9% male, median age 51, 42–63 years). After ablation, a median RR interval shortening of 28.3 (25.6–40.3)% occurred (1111, 937.5–1395.4 ms to 722.9, 652.2–882.4 ms, p = 0.0002). The AH interval also shortened (19, 10.5–35.7%) significantly after the procedure (115, 105–122 ms to 85, 71–105 ms, p = 0.0023) as well as Wenckebach cycle length (11.1, 5.9–17.8% shortening) from 450, 440–510 ms to 430, 400–460 ms, p = 0.0127. On 24-h Holter monitoring there was significant increase in heart rates (HR) of patients after ablation (minimal HR increased from 34 (26–43)bpm to 49 (43–56)bpm, p = 0,0102 and mean HR from 65 (47–72)bpm to 78 (67–87)bpm, p = 0.0004). No patients had recurrence of symptoms or significant bradyarrhythmias during a median follow-up of 8.4 months.ConclusionsA purely anatomic guided procedure directed only at the atrial right ganglionated plexi seems to be enough as a therapeutic approach for cardioneuroablation in selected patients with significant functional bradyarrhythmias.     

Global changes in bladder cancer mortality in the elderly

BackgroundBladder cancer is the 14th most common cause of cancer deaths worldwide and has a mean age of diagnosis of 73 years. Elderly people have fewer curative treatment options for muscle invasive bladder cancer. The aim of this study is to investigate how bladder cancer mortality has changed over the past forty years in different world regions to assess discrepancies between elderly and younger patients with bladder cancer.MethodsBladder cancer mortality data were extracted from the World Health Organisation’s GLOBOCAN database. Age-standardised mortality rates (ASMR) for bladder cancer were computed by year, sex, region and Human Development Index (HDI) using the world standard population.ResultsOverall ASMR in all available countries with data between 1986 and 2014 for men aged ≥ 75 has decreased from 101.2 to 89.9 per 100,000 (−11.2%). The decrease in ASMR for men < 75 has been 0.3–2.0 per 100,000 (−39.4%). In women aged ≥ 75 ASMR has decreased from 26.9 to 22.5 per 100,000 (−16.4%) and in women < 75 the ASMR has decreased from 0.76 to 0.56 per 100,000 (−26.4%).Correlation analysis showed a positive linear relationship between Human Development Index (HDI) and improvement in age-standardised mortality rate in all ages. Pearson’s coefficient showed that correlation was strongest in the 60–74 age group (r = −0.61, p < 0.001) and weakest in those aged ≥ 75 (r = −0.39, p = 0.01).ConclusionBladder cancer mortality is not improving in the elderly at the same rate as the rest of the population. Particular focus should be applied in future research to enhance and expand treatment options for bladder cancer that are appropriate for elderly patients.     

Late effects of childhood cancer treatment in long-term survivors diagnosed before the age of 3 years – A multicenter,nationwide study

BackgroundThe effect of age on the incidence of late sequelae that occur after anticancer treatment in childhood is still not fully elucidated. In this multicenter study of long-term survivors diagnosed before age of three, we investigated the prevalence of late effects many years after treatment.MethodsThe study group (n = 561) was selected from the Polish National Childhood Cancer Survivors Registry (n = 1761) created in 2007. A survivor was defined as an individual who has survived at least 5 years after completion of anticancer treatment. All children were diagnosed between 1991 and 2016, mean age at diagnosis was 1.82 years (range 0.03–2.99) and median follow up time - 9.85 years (range 5.0–23.6). They were treated in accordance with international protocols approved by the Polish Pediatric Leukemia and Lymphoma Group and Polish Solid Tumor Group. Chemotherapy alone was used in 192 (34.2%), chemotherapy and radiotherapy – 56 (10%), chemotherapy and surgery – 176 (31.4%), chemotherapy, radiotherapy, and surgery – 79 (14.1%), and surgery alone in 58 patients (10.3%).ResultsOf all patients enrolled to the study, only 94 (16.8%) had normal function of all organs. Seventy-six (13.5%) children developed dysfunction in one organ, another 83 (14.8%) had symptoms or complaints suggestive of dysfunction in two organs or systems, 88 (15.7%) had abnormalities in three organs, and 220 (39.2%) had at least four or more dysfunctions. In the entire study group, dysfunctions most frequently (> 20% of cases) involved the following organs/systems: circulatory – 21.8%, urinary – 30.8%, gastrointestinal – 20.8%, immune – 23.5%, vision – 20.7%, hearing – 21.8%, and oral and masticatory dysfunction – 26.9%. We did not find any significant differences in organ dysfunction between children diagnosed under the age of 1 and those diagnosed at the age of 1–3, except for a lower incidence of thyroid abnormalities (p = 0.007) and the higher prevalence of liver dysfunction in youngest patients. In the subset with longer follow-up period (> 10 years) more frequent thyroid abnormalities (p = 0.019), male (p = 0.002) and female (p = 0.026) gonads dysfunction, as well as musculoskeletal problems (p < 0.001) were observed. Among subjects who received radiotherapy compared to those who did not, short stature (p = 0.001), and dysfunction of the following systems/organs – circulatory (p = 0.049), urinary (p = 0.012), thyroid gland (p < 0.0001), nervous (p = 0.007), immunological (p = 0.002), liver (p = 0.03), dental or chewing difficulties (p = 0.001), hearing (p = 0.001) and musculoskeletal (p = 0.026) were more frequently reported. When multimodal therapy was applied (chemotherapy, radiotherapy, and surgery) a higher incidence of short stature (p = 0.007), urinary system disorders (p < 0.0001), thyroid dysfunction (p < 0.0001), hearing loss (p < 0.0001), and skin problems (p = 0.031) were observed.ConclusionThis study confirms that radiotherapy and some specific toxicity of cytostatics are the most important factors affecting organ function. Apart from a higher incidence of liver dysfunction in the youngest patients, there were no significant differences in organ and system toxicities between children diagnosed under the age of 1 and those diagnosed at the age of 1–3. We have shown that this group requires systematic, careful and long-term follow-up.     

Time dependent decline of neutralizing antibody titers in COVID-19 patients from Pune,India and evidence of reinfection

PurposeTo assess modulation of neutralizing antibody titers in COVID-19 patients and understand association of variables such as age, presence of comorbidity, BMI and gender with antibody titers.MethodsPatients (n = 100) diagnosed from 20th March 2020 to 17th August 2020 and treated at two large hospitals from Pune, India were included and followed up (clinical and serologic) for varied periods. IgG-anti-SARS-CoV-2 (Spike protein-based ELISA) and neutralizing antibody titers (NAb, PRNT) were determined in all the samples.ResultsOf the 100 patients enrolled initially (median 60 days of diagnosis), follow up samples were collected from 70 patients (median 106 days of diagnosis). Overall, NAb titers reduced significantly (p < 0.001) and as early as 3–4 months. During two visits, 20% and 7.1% patients reported some symptoms. At the first visit, NAb titers were higher in patients with severe disease (p < 0.001), comorbidities (p < 0.005), age <50 years (p < 0.05) and male gender (p < 0.05). Multivariate analysis identified older age (p < 0.001), duration post-diagnosis and female gender as independent variables influencing NAb titers (negative correlation, p < 0.05). During the follow-up, reduction in NAb titers was recorded in patients with comorbidity (p < 0.05), mild disease (p < 0.05), age <50 years (p < 0.05), higher BMI (p < 0.05) and male gender (p < 0.001). Serology identified six cases of asymptomatic reinfections.ConclusionsDecline of NAb titers was associated with age <50 years, mild disease, comorbidities, higher BMI and male gender. At the time of follow up, 8/70 (11.4%) patients lacked neutralizing antibodies. Evidence of 6 probable asymptomatic reinfections suggests waning of immunity, but, probable protection from clinical disease needing hospitalization.     

Long-term survival of patients with prostate cancer in Martinique: Results of a population-based study

BackgroundMartinique has one of the highest incidences of prostate cancer (PCa) worldwide. We analysed overall survival (OS) among patients with PCa in Martinique, using data from a population-based cancer registry between 2005 and 2014.MethodsThe log-rank test was used to assess the statistical differences between survival curves according to age at diagnosis, risk of disease progression including Gleason score, stage at diagnosis and Prostate Specific Antigen (PSA). A multivariable Cox model was constructed to identify independent prognostic factors for OS.ResultsA total of 5045 patients were included with a mean age at diagnosis of 68.1±9.0 years [36.0 – 98.0 years]. Clinical stage was analysed in 4999 (99.1% of overall), 19.5% were at low risk, 34.7% intermediate and 36.9% at high risk. In our study, 8.9% of patients with available stage at diagnosis, were regional/metastatic cancers. Median PSA level at diagnosis was 10.4 ng/mL. High-risk PCa was more frequent in patients aged 65-74 and ≥75 years as compared to those aged <65 years (36.6% and 48.8% versus 28.7% respectively; p<0.0001). One-year OS was 96.3%, 5-year OS was 83.4 and 10-year OS was 65.0%. Median survival was not reached in the whole cohort. High-risk PCa (HR=2.32; p<0.0001), regional/metastatic stage (HR= 9.51; p<0.0001) and older age (65-74 and ≥75 years - respectively HR=1.70; and HR=3.38), were independent prognostic factors for OS (p<0.0001).ConclusionThis study provides long term data that may be useful in making cancer management decisions for patients with PCa in Martinique.     

Safety and Efficacy of Apixaban versus warfarin in patients with atrial fibrillation or Venous Thromboembolism and End-Stage renal disease on hemodialysis: A systematic review and meta-analysis

BackgroundWarfarin is traditionally the drug of choice for stroke prophylaxis or treatment of venous thromboembolism in patients with end-stage renal disease (ESRD) on hemodialysis as data on apixaban use is scarce. We aimed to assess the safety and efficacy of Apixaban in patients with ESRD on hemodialysis when compared with warfarin.MethodsA comprehensive literature search in PubMed, Google Scholar, and Cochrane databases from inception until Nov 25, 2019, was performed. Studies reporting clinical outcomes comparing Apixaban (2.5 mg BID or 5 mg BID) versus Warfarin in ESRD patients on hemodialysis were included. Mantel-Haenszel risk ratio (RR) random-effects model was used to summarize data.ResultsFour studies (three retrospective and one randomized) with a total of 9862 patients (apixaban = 2,547, warfarin = 7315) met inclusion criteria. The overall mean age was 66.6 ± 3.9 years and mean CHA2DS2-VASc score 4.56 ± 0.58. Apixaban was associated with lower rates of major bleeding (RR 0.53, 95% CI 0.45–0.64, p < 0.0001], gastrointestinal (GI) bleed (RR 0.65, 95% CI 0.55–0.76, p < 0.0001), intracranial bleed (RR 0.56, 95% CI 0.36–0.89, p = 0.01), and stroke/systemic embolism [RR 0.65, 95% CI 0.52–0.83, p = 0.0004] compared with warfarin in patients with ESRD on hemodialysis. There was no significant increased risk of all-cause mortality with the apixaban vs. warfarin (RR 0.90, 95% CI 0.41–1.96, p = 0.78).ConclusionApixaban had an overall favorable risk-benefit profile, with significant reductions in ischemic stroke, major bleeding, and intracranial bleeding compared to Warfarin in ESRD patients on hemodialysis with non-valvular AF and/or venous thromboembolism.     

Phospholamban cardiomyopathy: a Canadian perspective on a unique population

Introduction

Phospholamban cardiomyopathy is an inherited cardiomyopathy, characterised by a defect in regulation of the sarcoplasmic reticulum Ca²⁺ pump, often presenting with malignant arrhythmias and progressive cardiac dysfunction occurring at a young age.

Methods

Phospholamban R14del mutation carriers and family members were identified from inherited arrhythmia clinics at 13 sites across Canada. Cardiac investigations, including electrocardiograms, Holter monitoring (premature ventricular complexes, PVCs), and imaging results were summarised.

Results

Fifty patients (10 families) were identified (median age 30 years, range 3–71, 46% female). Mutation carriers were more likely to be older, have low-voltage QRS, T‑wave inversion, frequent PVCs, and cardiac dysfunction, compared to unaffected relatives. Increasing age, low-voltage QRS, T‑wave inversion, late potentials, and frequent PVCs were predictors of cardiac dysfunction (p < 0.05 for all). Older carriers (age ≥45 years) were more likely to have disease manifestations than were their younger counterparts, with disease onset occurring at an older age in Canadian patients and their Dutch counterparts.

Discussion

Among Canadian patients with phospholamban cardiomyopathy, clinical manifestations resembled those of their Dutch counterparts, with increasing age a major predictor of disease manifestation. Older mutation carriers were more likely to have electrical and structural abnormalities, and may represent variable expressivity, age-dependent penetrance, or genetic heterogeneity among Canadian patients.

     

A national study of alcohol consumption patterns among population-based U.S. cancer survivors compared with cancer-free individuals

BackgroundThis study characterized alcohol consumption behaviors among adult cancer survivors and determined how these behaviors compared with cancer-free individuals using NHANES data (1999–2016).MethodsAdjusted odds ratios (aOR) and 95% confidence intervals (CI) were estimated using multinomial logistic regression for the association between cancer survivors vs cancer-free individuals and odds of drinking status (former/current/never drinkers), accounting for demographic and socioeconomic factors. Among current drinkers, multivariable logistic regression was used to calculate the aORs for binge drinking and exceeding moderate drinking. Results: A total of 3113 survivors and 39,527 cancer-free individuals were included. Cancer survivors were less likely to be current drinkers (63.4% vs. 72.6% in cancer-free) and were more likely to be former drinkers (24.4% vs. 15.5% in cancer-free). Cancer survivors had significant lower odds of being current vs. never drinkers (aOR, 0.84, 95% CI: 0.71–0.99). By cancer types, cervical cancer survivors were more likely to be binge drinkers (aOR, 2.51, 95% CI: 1.27–4.92), particularly among women aged ≥ 55 years (aOR, 6.90, 95% CI: 1.28–37.3).ConclusionGiven the high odds of binge drinking among cervical cancer survivors, public health strategies are needed to reduce alcohol consumption in this group.     

Health of children born to childhood cancer survivors: Participant characteristics and methods of the Multicenter Offspring Study

IntroductionResearch on childhood cancer survivor offspring has been limited to genetic disease occurrence, malformations or non-hereditary cancers. However, previous surveys indicated that survivors harbor fears about their (prospective) children's overall health. Our Multicenter Offspring Study examined extensive health aspects in children born to survivors and their siblings providing comprehensive information to be used in patient counseling to elucidate and alleviate existing concerns.MethodsUsing a specifically designed questionnaire, childhood cancer survivors and their siblings were surveyed on their offspring’s health (Supplementary material). Recruitment strategies depended on local infrastructures and standards of participating centers, including registry-based and direct approaches. Group differences were tested non-parametrically and effect sizes were calculated.ResultsIn total, 1126 survivors reported on 1780 offspring and 271 siblings reported on 441 offspring. Response rates ranged from 32.1% (Czech Republic) to 85.0% (Austria). Respondents were more likely to be female (p = .007), older at time of survey (p < .001), diagnosed 1980–1999 (p < .001) and treated with chemotherapy (p < .001). Compared to siblings, survivors were younger at time of survey (35 years vs. 39 years, p < .001) and at first birth (29 years vs. 30 years, p < .001). Survivor and sibling offspring only differed in terms of age at survey (6.3 years vs. 8.9 years, p < .001).ConclusionThe Multicenter Offspring Study investigates a wide variety of health aspects in offspring born to survivors and their siblings in five European countries. Our study cohorts form a solid basis for future analyses; yet, certain limitations, due to differences in approach among participating centers, must be considered when interpreting findings.     

Has the cancer-related death trend been changing in Turkey? An evaluation of the period between 2009 and 2019

BackgroundThe objective of this study was to determine the trend of cancer-related death rates between 2009 and 2019 in Turkey for all cancers combined and the five cancer types with the highest mortality: lung, stomach, pancreas, breast, and colon cancers.MethodsCancer mortality data were obtained from the Turkish Statistical Institute (TURKSTAT) and standardized by age using the World Health Organization (WHO) standard population ratios. The change in cancer-related mortality over the years was evaluated using Joinpoint Regression Analysis (JRA).ResultsTotal cancer-related deaths increased by 2.2% annually between 2009 and 2014 and decreased by 2.9% annually between 2014 and 2019 (p < 0.05). Among men; lung cancer-related deaths increased by 2.4% annually between 2009 and 2014 and decreased by 3.4% annually between 2014 and 2019 (p < 0.05), stomach cancer-related deaths decreased by 5.1% annually between 2014 and 2019 (p < 0.05), colon cancer-related deaths increased by 5.8% annually between 2009 and 2015 and decreased by 3.3% annually between 2015 and 2019 (p < 0.05), pancreatic cancer-related deaths increased annually by 5.6% in 2009–2013 (p < 0.05). Among women; lung cancer-related deaths increased by 2.5% annually between 2009 and 2016 (p < 0.05), stomach cancer-related deaths increased annually by 2.3% between 2009 and 2014 and decreased annually by 4.5% between 2014 and 2019 (p < 0.05), colon cancer-related deaths increased by 2.5% annually between 2009 and 2017 (p < 0.05), pancreatic cancer-related deaths increased by 7.4% annually between 2009 and 2013 (p < 0.05) and breast cancer-related deaths increased by 2.2% annually between 2009 and 2019 (p < 0.05).ConclusionMortality data in Turkey are collected only by TURKSTAT, which raises concern regarding the incompletion of the data. While this might lead to underestimation, the trend shows that there has been a decrease in total cancer-related deaths in Turkey. Pancreatic cancer, on the other hand, gains a higher proportion in cancer-related deaths in Turkey as in the world. Increasing deaths from lung and breast cancer in women remind of the importance of tobacco control interventions and cancer screening programs.     

Safety and efficacy of cryoballoon versus radiofrequency ablation for atrial fibrillation in elderly patients: A real-world evidence

BackgroundThere are limited data describing the experience of radiofrequency (RF) vs. cryoballoon (CB) ablation for atrial fibrillation (AF) among elderly patients in the United States.MethodsWe conducted a retrospective analysis of patients ≥75 years of age undergoing index RF vs. CB ablation between January 2014 and May 2020 at our center. The choice of ablation technique was left to the operator's discretion. Major complications and efficacy, defined as freedom from any atrial tachyarrhythmia (ATA) lasting ≥30 s after one year of follow-up, were assessed in patients with index RF vs. CB ablation.ResultsIn our cohort of 186 patients, the median age was 78 (76–81) years, 54.8% were men, and 39.2% had persistent AF. The median CHA₂DS₂-VASc score was 4 (3–4), while the median duration of AF was 3 (1–7) years. The majority (n = 112, 60.2%) underwent RF ablation. The median procedure time was significantly lower in CB group (197 vs 226.5 min, p=<0.01). The incidence of complications was similar in the two sub-groups (RF: 1.8% vs. CB: 2.7%, p = 0.67). Similarly, arrhythmia-free survival rate on antiarrhythmic drugs at 1-year follow-up remained statistically comparable (63.4% vs. 68.9%, p = 0.33) between patients receiving RF vs. CB ablation.ConclusionThe safety and efficacy of RF vs. CB ablation for AF remained comparable in our cohort of patients older than 75 years. CB ablation was associated with a shorter procedure time.     

Epidemiology of laryngeal cancer in Brazil: Historical data from 2000 to 2019

IntroductionTo determine the incidence, morbidity, and mortality rate of laryngeal cancer in two decades and its epidemiological, clinical, and histological characteristics by sex in Brazil.MethodsThis ecological study used three reliable sources of secondary data: population- and hospital-based cancer registries and the national mortality database. All data available from 2000 to 2019 were considered.ResultsThe incidence of male laryngeal cancer decreased from 9.20 to 4.95 per 100,000 from 2000 to 2018, while mortality slightly decreased from 3.37 to 3.30 per 100,000 from 2000 to 2019. In the same period, the female incidence decreased from 1.26 to 0.48 per 100,000; however, mortality slightly increased from 0.34 to 0.36 per 100,000. Of 221,566 individuals with head and neck cancer, 27 % presented laryngeal cancer. The median age was 61 years (54−69), and most individuals were male (86.6 %), smokers (66.2 %), diagnosed with locally advanced cancer (66.7 %), and squamous cell carcinoma as the main histological type (93.2 %). Male tended to be older (p < 0.001), white (p < 0.001), smokers (p < 0.001), and present late treatment initiation (p < 0.001) and early death (p < 0.001) compared with female.ConclusionThe male laryngeal cancer affected mainly at productive age but with a decreased incidence, probably due to a reduction in smoking habit. However, mortality did not change, which may be explained by the late diagnosis and lack of access to radiotherapy.     

The relationship between ethnicity,social deprivation and late presentation of colorectal cancer

IntroductionTumour staging at time of presentation is an important factor in determining survival in colorectal cancer. The aim of this paper is to investigate the relationship between ethnicity and deprivation in late (Stage IV) presentation of colorectal cancer.MethodsData from the Thames Cancer Registry comprising 77,057 colorectal cancer patients between the years 2000 and 2012 were analysed.ResultsA total of 17,348 patients were identified with complete data, of which 53.9% were male. Patients from a Black Afro/Caribbean background were diagnosed with CRC at a much younger age than the White British group (median age 67 compared with 72, p < 0.001). In multiple regression, ethnicity, deprivation and age were positive predictors of presenting with advanced tumour stage at time of diagnosis. Black patients were more likely to present with Stage IV tumours than white patients (OR 1.37, 95% CI 1.18–1.59, p < 0.001). Social deprivation was also a predictor of Stage IV cancer presentation, with the most deprived group (Quintile 5) 1.26 times more likely to be diagnosed with Stage IV cancer compared with the most affluent group (CI 1.13–1.40, p < 0.001). Sub-group analyses demonstrated that Black & Affluent patients were still at greater risk of Stage IV CRC than their White & Affluent counterparts (OR 1.24, 95% CI 1.11–1.45, p = 0.023). Patients with rectal cancer were less likely to present with Stage IV CRC (OR 0.66, 95% CI 0.61–0.71, p < 0.001).ConclusionRacial and age related disparities exist in tumour presentation in the United Kingdom. Patients from black and socially deprived backgrounds as well as the elderly are more likely to present with advanced tumours at time of diagnosis.     

Regional trends of minimally invasive radical hysterectomy for cervical cancer and exploration of perioperative outcomes

IntroductionRadical hysterectomy (RH) with bilateral pelvic lymph node dissection is the standard treatment for early stage cervical cancer which can be performed either by an abdominal or a minimally invasive (MIS) approach. In 2018, Ramirez et al. presented their randomized-controlled trial data which demonstrated that patients who were treated with minimally invasive surgical (MIS) radical hysterectomy (RH) had higher rates of locoregional disease recurrence and lower rates of overall survival when compared to patients treated with an abdominal approach. The objective of this study is to examine the trends in management of patients diagnosed with cervical cancer in New York State (NYS) and to analyze their perioperative outcomes.MethodsUsing the Statewide Planning and Research Cooperative System (SPARCS) Database, patients undergoing RH for early stage cervical cancer in NYS between the years of 2007–2015 were identified and categorized based on surgical approach. Demographic information was collected and multivariable regression was conducted to assess the impact of hysterectomy approach on perioperative outcomes.ResultsIn NYS, 5575 patients were treated with RH for early stage cervical cancer with 3257 (58.4%) treated by abdominal RH and 2318 (41.6%) treated with MIS RH. Between the years of 2007 and 2015, patients diagnosed with cervical cancer treated with MIS RH increased from 25.7% to 48.3% respectively. Surgeons performing MIS RH were more likely to be younger (average age 47.1 vs 49.2, p < 0.001) and have less time elapsed from their fellowship graduation (20.37 vs 22.64 years, p < 0.001). Patients who saw high volume doctors (OR 1.95, CI 1.65–2.31) and were seen in high volume facilities (OR 1.40, CI 1.18–1.65) were more likely to undergo MIS RH compared to abdominal RH. Patients who underwent MIS RH were more likely to be discharged home as opposed to acute rehab or nursing facility, when compared to patients treated with abdominal RH (98.5 vs 94.2% p < 0.001). When analyzing perioperativce outcomes, patient undergoing MIS RH had a 85% decrease in length of hospital stay compared to abdominal RH, a 40% reduction in 30-day readmission rates, and a 10% reduction in hospital costs respectively.DiscussionIn our study period, between the years of 2007 and 2015, the number of cervical cancer cases treated with MIS RH increased from 25.7% to 48.3%. MIS techniques led to a reduction in length of hospital stay, patient readmission rates, and hospital costs. Based on recent data from Ramirez et al., preliminary data demonstrated decrease in MIS RH for treatment of cervical cancer after presentation of the LACC trial and our data confirmed these reported trends in NYS. With this change in surgical practice, there will be associated changes in perioperative outcomes. Moreover, for patients diagnosed with cervical cancer with microscopic disease or previous treatment with an excisions procedure, MIS approach should be considered for improvement in perioperative outcomes as long as oncologic outcomes are not compromised.     

Time-to-cure and cure proportion in solid cancers in France. A population based study

BackgroundIn cancer care, the cure proportion (P) and time-to-cure (TTC) are important indicators for practitioners, patients, and healthcare policy makers. The recent definition of TTC as the time at which the probability of belonging to the cured group reaches 95% was used for the first time.MethodsThe data stem from the common database of French cancer registries including 335,358 solid tumours diagnosed between 1995 and 2009 at 27 sites. P and TTC were estimated through a flexible parametric net survival cure model for each cancer site, sex, and age at diagnosis with acceptable assumption of cure (excess mortality rate ≤0.05).ResultsTTC was ≤5 years and P was >80% for skin melanoma and thyroid and testis cancers. It was 0 for testis cancer in men <55 and for thyroid cancer in men <45 and women <65. TTC was between 5 and 10 years for all digestive cancers except small intestine and all gynaecologic cancers except breast. It was ≥10 years in prostate, breast, and urinary tract. The range of P according to age and sex was 37–79% for urinary tract 72–88% for prostate and breast, 4–16% for pancreatic and 47–62% for colorectal cancer.ConclusionTime-to-cure was estimated for the first time from a large national database and individual probabilities of cure. It was 0 in the younger patients with testis or thyroid cancer and <12 years in most cancer sites. These results should help improve access to credit and insurance for patients still alive past the estimated TTCs.     

Características basales de los pacientes nonagenarios ingresados por fracaso renal agudo en comparación con otros grupos etarios

BackgroundThe increase in life expectancy leads to higher hospitalisation rates in elderly patients. The aim of this work is to study the characteristics of the population over 90 years of age that are admitted due to acute kidney injury (AKI).Material and methodsA cross-sectional study was conducted that included all patients admitted to hospital with AKI in the years 2013 and 2014. Epidemiological characteristics, comorbidity, medication and baseline analytical data were collected, and a comparison was made between patients with age over 90 years-old and the others.ResultsA total of 1733 patients were included, of whom 264 (15%) were over 90 years-old. A significantly higher proportion of these patients were women. The most frequent cause of AKI in patients older than 90 years was functional (81%) (p < 0.001 compared to other age groups). The main cause of hospital admission was infection. In the group of over 90 years of age, a higher prevalence was found for arterial hypertension (p = 0.005), chronic kidney disease (p = 0.014), congestive heart failure (p = 0.006), and cognitive impairment (p < 0.0001). The baseline glomerular filtration rate by CKD-EPI was lower in the group of patients older than 90 years (p < 0.0001). Patients under 90 years admitted to hospital due to AKI, had a higher prevalence of diabetes mellitus (p < 0.001), dyslipidaemia (p < 0.001), history of neoplasia (p < 0.001), and a higher Barthel index (p < 0.0001).ConclusionsNonagenarians admitted due to AKI have functional aetiology as the most common factor. These patients have a higher prevalence of hypertension, heart failure, chronic kidney disease, low functional status, and more cognitive impairment.     

Trends in disability-adjusted life years of lung cancer among women from 2004 to 2030 in Guangzhou,China: A population-based study

BackgroundForecast of disease burden in lung cancer is an important health agenda. One of the main challenges is to predict the evolution of trends in disability-adjusted life year (DALY) of lung cancer so as to anticipate the future burden and to coordinate the supply of sufficient health services and care.MethodsUsing 2004–2013 cancer registry data in Guangzhou, we fitted Bayesian age-period-cohort models with age, period, and cohort effects to analyze trends of lung cancer among women, and then made forecast for DALY of lung cancer until 2030.ResultsDuring 2004–2013, there was an annual average of 10,582 DALYs for lung cancer (15.84% of total DALY). In 2014–2030, DALY is expected to reach 234,752 person-years for lung cancer (12.25% of total DALY), with an annual mean of 13,809 DALYs. Lung cancer crude DALY rate is projected to rise steadily from 257.56 (95% uncertainty interval: 165.97–361.22) in 2014 to 316.99 (219.96–419.41) per 100,000 women in 2030, and the rise is mainly seen in 45–64 years age group. Lung cancer DALY rate remains the highest in the 65–89 years age group.ConclusionsWomen at 65–89 years carry the highest lung cancer burden among other age groups in Guangzhou. The DALY rate of lung cancer is projected to increase most precipitously for the 45–64 years age group. This indicates that concerted efforts are needed to develop adequate cancer services, and to reassess health resources for control and care of lung cancer in these populations.     

Temporal trends and factors associated with the cancer diagnosed at stage IV in patients included in the integrated hospital-based cancer registry system in Brazil in two decades

BackgroundIn several countries, such as Brazil, the oncological diagnosis usually occurs at an advanced stage of the disease. Thus, the aim of this study was to investigate temporal trends and factors associated with the cancer diagnosed at stage IV in Brazil in two decades.MethodsSecondary-based study, with time series analysis for trend assessment and cross-sectional of factors associated with diagnosis of female breast, prostate, cervix uteri, colorectal, lung, stomach, lip and oral cavity, thyroid, esophagus or corpus uteri at stage IV.Results1,218,322 cases were evaluated. The types of cancer with the highest proportion of stage IV at diagnosis in men and women, respectively, were: lung (53.7% and 57.4%), stomach (48.4% and 45.0%) and lip/oral cavity (53.5% and 43.4%). Most showed an increasing trend of annual percent change of cancer diagnosed at stage IV, being more pronounced in corpus uteri cancer (2013–2019: +7.4%, p < 0.001). The odds of cancer diagnosed at stage IV were associated with different factors, according to primary tumor site, but marked by the inverse association with female sex [odds ratio (OR) ranging from 0.42 to 0.91, p < 0.001] and direct association in cases with < 7 years of study (OR ranging from 1.08 to 1.81, p < 0.001), living without a partner (OR ranging from 1.06, p < 0.050 to1.27, p < 0.001), living in the South and Southeast regions (OR ranging from 1.04 to 1.13, p < 0.001), with more than one tumor (OR ranging from 1.19, p < 0.050 to 1.54, p < 0.001) and treated in Centers of High Complexity in Oncology (OR ranging from 1.03, p < 0.050 to1.24, p < 0.001).ConclusionThere was a high frequency of cancer diagnosed at stage IV and an increasing trend in different cancer types, which were associated with distinct sociodemographic, lifestyle, and clinical factors.     

Predictors of treatment initiation and mapping the cancer diagnostic pathway: A retrospective observational cohort study of patients with metastatic non-small cell lung cancer

BackgroundHealth-care providers in the US revealed that a substantial proportion of mNSCLC patients do not receive any first-line therapy and the biggest gaps in care are time inefficiencies in the diagnostic process. The goal of this study was to determine whether such gaps are found in Israel where healthcare is universal and participation in a medical insurance plan is free and compulsory.MethodsWe conducted a retrospective, observational cohort study using the computerized data of Maccabi Healthcare Services, a 2.5 million-member state-mandated health-service. Patients with mNSCLC diagnosed between 2017 and 2018 were followed until December 2019.ResultsAmong 434 patients (62% male, mean age 68 y, 74% adenocarcinoma), 345 (79%) initiated first-line treatment. Compared to treated, untreated patients (n = 89) were more likely to be older (mean [SD]=71 years [10] vs. 67 [10], p < 0.001), have a higher co-morbidity index (5.6 ([4.4] vs. 4.0 [3.4], p < 0.001), smokers (84% vs. 66%, p = 0.001), and require hospitalization in the year prior to diagnosis (80% vs 61%, p = 0.002). There was no difference in socioeconomic status. Time from first symptom to imaging was longer for untreated than treated patients (6.51 months [4.24, 7.33] vs 3.48 months [2.76, 4.34] respectively, p = 0.22). Predictors of treatment initiation included age< 70 years, non-smokers, EGFR testing performed, ECOG performance status 0–1 and shorter wait from first symptom to imaging. Median time from first symptom to initiation of 1 L, was 7.76 months (6.51–8.75).ConclusionThe proportion of untreated mNSCLC patients are comparable to those reported in the US; we did not find health disparities between socioeconomic levels. Our data suggest that the main barrier to effective diagnostic process is the wait between symptom complaint and imaging.
