Association of DNA repair gene polymorphisms with response to cisplatin-based concurrent chemoradiotherapy in patients with cervical carcinoma

PurposeThe aim of this study was to investigate polymorphisms in DNA repair genes as potential predictive factors among Chinese cervical cancer patients.MethodsA total of 72 patients with cervical carcinoma, who received cisplatin-based chemoradiotherapy and whose responses were evaluated by Response Evaluation Criteria in Solid Tumors, were included. The association between response to chemoradiotherapy and the genotypes for 29 single-nucleotide polymorphisms (SNPs) in 25 DNA repair genes were analyzed.ResultsA minor allele of SNP rs9350 in the exonuclease 1 gene was associated with a better response rate, regardless of age and tumor stage (odds ratio, 8.316; p = 0.002).ConclusionSNP rs9350 in the exonuclease 1 gene is involved in inter-individual differences in the response to cisplatin-based chemoradiotherapy, in patients with cervical carcinoma.     

CCND1 as a predictive biomarker of neoadjuvant chemotherapy in patients with locally advanced head and neck squamous cell carcinoma

Background

Cyclin D1 (CCND1) has been associated with chemotherapy resistance and poor prognosis. In this study, we tested the hypothesis that CCND1 expression determines response and clinical outcomes in locally advanced head and neck squamous cell carcinoma (HNSCC) patients treated with neoadjuvant chemotherapy followed by surgery and radiotherapy.

Methodology and Findings

224 patients with HNSCC were treated with either cisplatin-based chemotherapy followed by surgery and radiotherapy (neoadjuvant group, n = 100) or surgery and radiotherapy (non-neoadjuvant group, n = 124). CCND1 expression was assessed by immunohistochemistry. CCND1 levels were analyzed with chemotherapy response, disease-free survival (DFS) and overall survival (OS). There was no significant difference between the neoadjuvant group and non-neoadjuvant group in DFS and OS (p = 0.929 and p = 0.760) when patients treated with the indiscriminate administration of cisplatin-based chemotherapy. However, in the neoadjuvant group, patients whose tumors showed a low CCND1 expression more likely respond to chemotherapy (p<0.001) and had a significantly better OS and DFS than those whose tumors showed a high CCND1 expression (73% vs 8%, p<0.001; 63% vs 6%, p<0.001). Importantly, patients with a low CCND1 expression in neoadjuvant group received more survival benefits than those in non-neoadjuvant group (p = 0.016), however patients with a high CCND1 expression and treated with neoadjuvant chemotherapy had a significantly poor OS compared to those treated with surgery and radiotherapy (p = 0.032). A multivariate survival analysis also showed CCND1 expression was an independent predictive factor (p<0.001).

Conclusions

This study suggests that some but not all patients with HNSCC may benefit from neoadjuvant chemotherapy with cisplatin-based regimen and CCND1 expression may serve as a predictive biomarker in selecting patients undergo less than two cycles of neoadjuvant chemotherapy.     

Survival among clinical stage I–III rectal cancer patients treated with different preoperative treatments: A population-based comparison

BackgroundRadical resection is regarded as the cornerstone of rectal cancer treatment. Preoperative (chemo)radiotherapy and adjuvant chemotherapy are often administered. This population-based study compares the survival in clinical stage I–III rectal cancer patients who received either preoperative radiotherapy, preoperative chemoradiotherapy or no preoperative therapy. As secondary research questions, the association of type of radical resection and adjuvant chemotherapy on survival is also investigated.MethodsPatients diagnosed between January 2006 and December 2011 with stage I–III rectal adenocarcinoma were retrieved from the Belgian Cancer Registry database. Multivariable Cox proportional hazards regression models were applied to evaluate the association of preoperative treatment, type of radical resection and use of adjuvant chemotherapy with survival, adjusting for the baseline characteristics age, gender, WHO performance status and clinical stage.ResultsA total of 5173 rectal cancer patients were identified. Preoperative treatment was as follows: none in 1354 (26.2%), radiotherapy in 797 (15.4%) and chemoradiotherapy in 3022 (58.4%) patients. The patient group who did not receive preoperative therapy or radiotherapy followed by radical resection had a lower observed survival compared to the patient group receiving preoperative chemoradiotherapy. The patient groups who underwent abdominoperineal excision and those receiving adjuvant chemotherapy had a worse observed survival compared to the patient group treated with sphincter-sparing surgery and no adjuvant therapy respectively. These effects were age-dependent. Multivariable analysis demonstrated similar findings for the observed survival conditional on surviving the first year since surgery.ConclusionIn this population-based study among clinical stage I–III rectal cancer patients treated with radical resection, a superior observed survival was noticed in the patient group receiving preoperative chemoradiotherapy compared to the patients groups receiving no or preoperative radiotherapy only, adjusting for case mix, type of radical resection and adjuvant chemotherapy. Additionally, higher adjusted observed survival was also detected for the patient groups with sphincter-sparing surgery or no adjuvant chemotherapy.     

A case-control study on selenium,zinc, and copper in plasma and hair of subjects affected by breast and lung cancer

The purpose of our study was to investigate the relationship between plasma and hair levels of Se, Zn, and Cu, and cancer. We selected a total of 66 patients affected by either breast (38) or lung (28) cancer. They entered into the study at the onset of disease, and before any chemical or radiotherapy. Controls were randomly selected among healthy people and were matched for sex, age, smoking habits, and residence. In the group of breast cancer, a significant decrease in hair Se was found compared to controls (p<0.01), whereas plasma Se was only slightly decreased. No difference between cases and controls was detected in both hair and plasma levels of Zn and Cu. Subjects who developed lung cancer were significantly lower in hair Zn (p<0.05) and Cu (p<0.01) than controls, whereas there was no difference with regard to Se. In addition, plasma Cu of these patients was increased as compared to controls.

The impact of GGH -401C > T polymorphism on cisplatin-based chemoradiotherapy response and survival in cervical cancer

Aims

Cervical cancer is the third most frequent cancer in women worldwide, mostly treated with cisplatin-based chemoradiotherapy. Since it is known that folate metabolism might interfere with cisplatin effectiveness, we intended to study the influence of the Gamma Glutamyl Hydrolase -401C > T polymorphism in treatment response in cervical cancer.

Methods

We retrospectively reviewed the clinical data of 167 patients with bulky cervical cancer submitted to cisplatin-based chemoradiotherapy. The genotypes of GGH -401C > T SNP were determined by real-time PCR and statistical analysis was performed by χ² test and survival analysis.

Results

The genotypes of GGH-401C > T were significantly associated with the response to platinum-based chemoradiotherapy. Treatment response was higher in patients carrying the CC genotype, who presented a significant increased chance of treatment response (survival time in months/genotype: 91 for CC Vs 72 for CT/TT; p = 0.035, log rank test). A Cox regression analysis accordingly showed that the presence of the T allele was significantly linked to a worse treatment response (HR = 3.036; CI 95% 1.032-8.934, p = 0.044).

Conclusions

The results of our study suggested the potential interest of GGH -401C > T as a predictive factor of the outcome of cervical carcinoma treated with cisplatin-based chemoradiotherapy.     

Serum and tissue levels of six trace elements and copper/zinc ratio in patients with cervical cancer and uterine myoma

The aim of this study is to investigate the relationship between trace elements and the incidence of cervical cancer. Tissue and serum levels of six elements (Cu, Zn, Fe, Mn, Ca, and Se) and the Cu/Zn ratio in 40 cases of patients with cervical cancer, 30 cases of uterine myoma, and 50 healthy subjects were measured by atomic absorption spectrophotometry; the selenium content was determined by atomic fluorescence spectrometry. The results showed that the tissue contents of Zn, Se, and Ca were significantly lower and the Cu and Fe concentrations and Cu/Zn ratio were significantly higher in cervical cancer tissue than that for paired nonlesion tissue (p<0.02 and p<0.001, respectively). The serum levels of Zn, Se, Ca, and Fe were lower and Cu and Mn levels and Cu/Zn ratio were higher in patients with cervical cancer than in healthy subjects (p<0.01 and p<0.001, respectively) and in the uterine myoma group compared with healthy subjects (p< 0.05–0.001). There are no significant differences in the contents of six elements and the Cu/Zn ratio between uterine myoma tissue and paired nonlesion tissue. The results showed also that the Fe level and Cu/Zn ratio were significantly higher and the Zn and Se levels were significantly lower in cervical cancer tissue than in uterine myoma tissue (p<0.01 and p<0.001, respectively). The serum Cu level and Cu/Zn ratio were significantly higher in the cervical cancer group than the uterine myoma group (p<0.01). Data were also analyzed using multivarate logistic regression. After adjustment for age, occupation, life habit, and other covariates for the development of cervical cancer, the odds ratios were 22.64 (95% confidence interval [CI]: 5.64–90.88, p=0.001) for Cu, 0.11 (95% CI: 0.034–0.373; p=0.005) for Zn, and 0.60 (95% CI: 0.36–0.99, p=0.01) for Se. Thus, the serum and tissue levels of Cu increase and the deficiency of Zn and Se may be risk factors for the development of cervical cancer.     

Intensity modulated radiotherapy in carcinoma cervix with metastatic para-aortic nodes: an institutional experience from a Regional Cancer Centre of Eastern India

BackgroundCervical cancer is a major health problem, especially in developing countries like India. Extended field radiotherapy (EFRT) for cancer cervix treatment remains a challenging task for radiation oncologists. In the last decade studies have shown that EFRT using intensity modulated radiotherapy (IMRT) is feasible in treating gynaecological malignancies but there is a dearth of literature on this specific topic from this part of the world where patient profile differs greatly in several aspects from that of the western world. The aim of the study was evaluation of treatment response and toxicity profile in cases of carcinoma cervix with metastatic para-aortic nodes treated with intensity modulated radiotherapy technique.Materials and methodsIn this retrospective study the treatment records of 45 para-aortic node positive cervical cancer patients treated with EFRT (IMRT) and concurrent cisplatin were analysed for evaluation of loco-regional control and toxicities.ResultsForty-four patients received full course of treatment. Among those 44 patients, 93.2% achieved complete response. Overall, the treatment was tolerated well and toxicities were within acceptable limits. Acute grade 3–4 toxicities were observed mostly in the form of anaemia and leucopenia. Most common late toxicities were those of small and large intestine.ConclusionEFRT with concurrent chemotherapy was successfully delivered for para-aortic nodes positive cervical cancer patients in Indian scenario where under-nutrition, infection, anaemia and several other factors adversely influence treatment outcome. Pelvic and para-aortic control rates were satisfactory. The technique was associated with an acceptable acute and late toxicity profile.

Correlation analysis of lymphocyte-monocyte ratio with pathological complete response and clinical prognosis of neoadjuvant chemotherapy in patients with breast cancer

PurposeInflammation plays an important role in tumor proliferation, metastasis, and chemotherapy resistance. Peripheral blood lymphocyte-monocyte ratio (LMR) has been reported to be closely associated with the prognosis of many tumors, such as certain hematologic malignancies and gastric cancer. However, the association in breast cancer is still not clear. This study investigated the relationship between LMR with pathological complete response and clinical prognosis of neoadjuvant chemotherapy in patients with breast cancer, to provide convenient and accurate predictive indicators for pathological complete response (pCR) and prognosis.MethodsThe clinicopathological data of 192 female breast cancer patients who received neoadjuvant chemotherapy and surgery in Harbin Medical University Tumor Hospital from January 2013 to August 2017 were retrospectively analyzed. Blood lymphocytes and monocytes were obtained by peripheral venous punctures.ResultsCompared with the low LMR group, pCR was more easily obtained in the high LMR group (P=0.020); Subgroup analysis showed that patients with the high LMR and HER-2(+) group were more likely to obtain pCR (P=0.011).Univariate andmultivariate results showed that the overall survival (OS) and disease free survival (DFS) of the high LMR group were longer than that of the low LMR group.ConclusionLMR and HER-2 status are correlated with pCR of neoadjuvant chemotherapy in breast cancer patients and are independent predictors of pCR after neoadjuvant chemotherapy in breast cancer patients. Meanwhile, both LMR and T stage of tumor are independent prognostic factors of breast cancer patients, with good predictive value.

Comparison of neoadjuvant oral chemotherapy with UFT plus Folinic acid or Capecitabine concomitant with radiotherapy on locally advanced rectal cancer

AimTo evaluate the differences in treatment response and the impact on survival with both oral agents (UFT and Capecitabine) as neoadjuvant chemotherapy administered concomitantly with radiotherapy.BackgroundThere are still no studies comparing the use of neoadjuvant oral chemotherapy either with UFT plus Folinic acid or Capecitabine concomitant with radiotherapy in locally advanced rectal cancer (LARC).Materials and methodsA set of 112 patients with LARC were treated preoperatively. GROUP 1 – 61 patients underwent concomitant oral chemotherapy with Capecitabine (825 mg/m² twice daily). GROUP 2 – 51 patients submitted to concomitant oral chemotherapy with UFT (300 mg/m²/d) + Folinic acid (90 mg/d) and radiotherapy. 57.1% of patients were submitted to adjuvant chemotherapy.ResultsGROUP 1: acute toxicity – 80.3%; pathological complete response (pCR) – 10.5%; tumor downstaging (TD) – 49.1%; nodal downstaging (ND) – 76.5%; loco-regional response (LRR) – 71.9%; toxicity to adjuvant chemotherapy – 75%. GROUP 2: acute toxicity – 80.4%; pCR – 28%; TD – 62%; ND – 75.6%; LRR – 78%; toxicity to adjuvant chemotherapy – 56%. There was no difference in survival nor loco-regional control between the groups.ConclusionsPatients treated with neoadjuvant oral UFT + Folinic acid had a higher rate of pathologic complete response than patients treated with Capecitabine concomitant with radiotherapy. There were no differences in downstaging, LRR, toxicity, survival or loco-regional control between both groups. There was a trend to a higher rate of toxicity to adjuvant chemotherapy in the Capecitabine group.     

Anaplastic thyroid cancer: outcomes of trimodal therapy

BackroundThe purpose of this study is to assess the impact of trimodal therapy [surgery, chemotherapy and external beam radiotherapy (EBRT)] in patients with anaplastic thyroid cancer (ATC) treated with curative intent.Materials and methodsRetrospective review of patients with ATC treated at a tertiary referral centre between January 2009 and June 2020. Data were collected regarding demographics, histology, staging, treatment and outcomes.ResultsSeven patients (4 female) were identified. Median age was 58 years (range 52–83 years). All patients received EBRT with concurrent doxorubicin. Six patients received surgery followed by chemoradiotherapy (CRT), and one underwent neoadjuvant CRT followed by surgery. Median radiological tumour size was 50mm (range 40–90 mm). Six patients had gross extrathyroidal extension and three had N1b disease. Prescribed radiotherapy schedules were 46.4 Gy in 29 bidaily fractions (n = 2, treated 2010), 60 Gy in 30 daily fractions (n = 2), 66 Gy in 30 fractions (n = 2) and 70 Gy in 35 fractions (n = 1; patient received neoadjuvant CRT). CRT was discontinued early for two patients due to toxicities. At median follow up of 5.8 months, 42.9% (3/7) patients were alive and disease-free. Only one patient developed a local failure. Three patients died from distant metastases without locoregional recurrence.ConclusionsDespite poor prognosis of ATC, selected patients with operable tumours may achieve high locoregional control rates with trimodal therapy, with possibility of long-term survival in select cases.     

血清ANXA2、ANXA6、ANXA7与乳腺癌患者聚乙二醇多柔比星脂质体相关新辅助化疗方案治疗疗效的关系研究

摘要 目的：探讨血清膜联蛋白A2（ANXA2）、膜联蛋白A6（ANXA6）、膜联蛋白A7（ANXA7）与乳腺癌患者聚乙二醇多柔比星脂质体（PLD）相关新辅助化疗方案治疗疗效的关系。方法：选择2019年11月至2022年12月于山西医科大学第一医院95例行PLD相关新辅助化疗的乳腺癌患者。新辅助化疗前检测所有乳腺癌患者的血清ANXA2、ANXA6、ANXA7水平。单因素和多因素Logistic回归分析影响乳腺癌患者PLD相关新辅助化疗疗效的因素。受试者工作特征（ROC）曲线分析血清ANXA2、ANXA6、ANXA7预测乳腺癌患者PLD相关新辅助化疗疗效的价值。结果：无效组新辅助化疗前血清ANXA2、ANXA6、ANXA7水平均高于有效组（P＜0.05）。TNM分期IIIA期、ER阳性、高水平ANXA2、高水平ANXA6、高水平ANXA7是乳腺癌PLD相关新辅助化疗无效的危险因素（P＜0.05）。血清ANXA2、ANXA6、ANXA7单独检测预测乳腺癌PLD相关新辅助化疗无效的曲线下面积分别为0.783、0.774、0.821,三指标联合检测预测的曲线下面积为0.923,高于各指标单独预测效能。结论：高ANXA2、ANXA6、ANXA7水平及TNM分期ⅢA期、ER阳性均是乳腺癌患者PLD相关新辅助化疗无效的危险因素,联合检测血清ANXA2、ANXA6、ANXA7水平可提高对乳腺癌患者PLD相关新辅助化疗疗效的预测效能。     

Influence of adjuvant radiotherapy on circulating epithelial tumor cells and circulating cancer stem cells in primary non-metastatic breast cancer

Background: There is an unmet need to identify biomarkers that directly reflect response to adjuvant radiotherapy (RT). Circulating epithelial tumor cells (CETCs) represent the liquid component of solid tumors and are responsible for metastatic relapse. CETC subsets with cancer stem cell characteristics, circulating cancer stem cells (cCSCs), play a pivotal role in the metastatic cascade. Monitoring the most aggressive subpopulation of CETCs could reflect the aggressiveness of the remaining tumor burden. There is limited data on the detection and monitoring changes in CETC and cCSC numbers during RT in early breast cancer.Methods: CETC numbers were analyzed prior to, at midterm and at the end of RT in 52 primary non-metastatic breast cancer patients. Hormone receptor status was determined in CETCs prior to and at the end of RT. For the identification of cCSCs cell suspensions from the peripheral blood of patients were cultured in vitro under conditions favoring growth of tumorspheres.Results: Hormone receptor status in CETCs before RT was comparable to that in primary tumor tissue. Prior to RT numbers of CETCs correlated with aggressiveness of primary tumors. cCSCs could be successfully identified and monitored during RT. Prior to RT patients treated with neoadjuvant chemotherapy had significantly higher numbers of CETCs and tumorspheres compared to patients after adjuvant chemotherapy. During RT, the number of CETCs decreased continuously in patients after neoadjuvant chemotherapy but not after adjuvant chemotherapy.Conclusion: Monitoring the number of CETCs and the CETC subset with cancer stem cell properties during RT may provide additional clinically useful prognostic information.
