Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy Improves Survival for Patients with Peritoneal Carcinomatosis from Colorectal Cancer: A Phase II Study from a Chinese Center

Background

Peritoneal carcinomatosis (PC) is a difficult clinical challenge in colorectal cancer (CRC) because conventional treatment modalities could not produce significant survival benefit, which highlights the acute need for new treatment strategies. Our previous case-control study demonstrated the potential survival advantage of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) over CRS alone. This phase II study was to further investigate the efficacy and adverse events of CRS+HIPEC for Chinese patients with CRC PC.

Methods

A total of 60 consecutive CRC PC patients underwent 63 procedures consisting of CRS+HIPEC and postoperative chemotherapy, all by a designated team focusing on this combined treatment modality. All the clinico-pathological information was systematically integrated into a prospective database. The primary end point was disease-specific overall survival (OS), and the secondary end points were perioperative safety profiles.

Results

By the most recent database update, the median follow-up was 29.9 (range 3.5–108.9) months. The peritoneal cancer index (PCI) ≤20 was in 47.0% of patients, complete cytoreductive surgery (CC0-1) was performed in 53.0% of patients. The median OS was 16.0 (95% confidence interval [CI] 12.2–19.8) months, and the 1-, 2-, 3-, and 5-year survival rates were 70.5%, 34.2%, 22.0% and 22.0%, respectively. Mortality and grades 3 to 5 morbidity rates in postoperative 30 days were 0.0% and 30.2%, respectively. Univariate analysis identified 3 parameters with significant effects on OS: PCI ≤20, CC0-1 and adjuvant chemotherapy over 6 cycles. On multivariate analysis, however, only CC0-1 and adjuvant chemotherapy ≥6 cycles were found to be independent factors for OS benefit.

Discussion

CRS+HIPEC at a specialized treatment center could improve OS for selected CRC PC patients from China, with acceptable perioperative safety.

Evaluation of Endarterectomy Recanalization under Ultrasound Guidance in Symptomatic Patients with Carotid Artery Occlusion

Rigorous screening and good imaging would help perform surgery on carotid artery occlusion CAO safely and effectively. The purpose of this study was to retrospectively evaluate carotid endarterectomy (CEA) recanalization in patients with common carotid artery occlusion (CCAO) or internal carotid artery occlusion (ICAO) with color Doppler flow imaging (CDFI). A total of 59 patients undergoing CEA were enrolled. According to the results of CEA, the patients were divided into successful recanalization (group A) and unsuccessful recanalization (group B) groups. The original diameter, lesion length, proximal-to-distal diameter ratio and echo characteristics of the lesion within the lumen of the carotid artery were recorded before CEA and compared between the two groups. In regards to the achievement of repatency by CEA, the overall success rate was 74.6% (44/59), the success rate in CCAO patients was 75.9% (22/29) and the success rate in ICAO patients was 73.3% (22/30). There was no significant difference in the success rates between the CCAO and ICAO patients (χ² = 0.050, P = 0.824). The overall rate of stroke and death within 30 postoperative days was 5.1% (3/59). For the CCAO patients, the lesion length in group A was shorter than that in group B (t = 3.221, P = 0.004). For the ICAO patients, the original diameter of the distal ICA was broader (t = 6.254, P = 0.000) and the proximal-to-distal ICA diameter ratio was smaller (t = 8.036, P = 0.000) in group A than in group B. The rate of recanalization for lumens with a homogeneous echo pattern (hypoecho or isoecho) was significantly higher than that for lumens with echo heterogeneity for both the CCAO and ICAO patients (χ² = 14.477, P = 0.001; χ² = 10.519, P = 0.003). However, for both the CCAO and ICAO patients, there was no difference in the rate of recanalization between patients with hypoecho and isoecho lesions (χ² = 0.109, P = 0.742; χ² = 0.836, P = 0.429). The original diameter, proximal-to-distal ICA diameter ratio, lesion length and echo characteristics may affect the success of CEA recanalization in patients with CCAO and ICAO. CDFI is helpful in screening patients with carotid artery occlusion and may improve the success rate of CEA.     

Medullary Thyroid Cancer that Stains Negative for CA 19-9 has Decreased Metastatic Potential

Objective: Presently, no clinical tools are available to diagnose the metastatic potential of medullary thyroid cancer (MTC) at disease presentation. Surveillance with calcitonin (Ct) and carcinoembryonic antigen (CEA) is currently recommended for the observation and diagnosis of metastatic disease after initial treatment of MTC. Recently, carbohydrate antigen (CA)19-9 staining has been associated with aggressive forms of MTC and metastatic spread. This pilot study explored whether positive CA19-9 staining of MTC tissue is associated with its metastatic potential.Methods: Sixteen cases of MTC were identified, and tissue specimens were immunostained for CA 19-9 and other MTC tumor markers. Clinical information about patients' MTC was collected through a retrospective chart review.Results: Overall, 63% of the specimens stained positive for CA19-9. The median size of positively staining specimens was 2.6 cm (interquartile range [IQR] 1.2-3.2) compared to 0.7 cm (0.5-1.2) in negatively staining MTC specimens (P = .04). All specimens from patients diagnosed with stage IV MTC stained positive for CA19-9, compared to only 40% of cases that were classified as stages I to III (P = .03). Furthermore, 100% of the primary specimens that were documented to have metastatic spread stained positive for CA19-9. The sensitivity for ruling out stage IV MTC based on negative staining for CA 19-9 was 100%.Conclusion: Based on these results, we conclude that negative staining of MTC for CA19-9 may be associated with its decreased metastatic potential.Abbreviations: CA = carbohydrate antigen CEA = carcinoembryonic antigen Ct = calcitonin IHC =immunohistochemistry MTC = medullary thyroid cancer     

Serum Levels of Carcinoembryonic Antigen in Patients with Type 2 Diabetes

Objective: To investigate whether serum carcinoembryonic antigen (CEA) levels are associated with type 2 diabetes mellitus (T2DM) and glycated hemoglobin (HbA1c).Methods: A comparative, cross-sectional, observational study was conducted at Jordan University Hospital, Amman, Jordan, on 282 adult subjects from March 2012 to June 2015. Subjects were classified into 2 groups: T2DM subjects (n = 168) and a healthy comparison group (n = 114). Subjects with any condition known to be associated with elevated CEA levels were excluded. HbA1c and serum CEA levels were measured, and body mass index (BMI) was determined.Results: Subjects with T2DM had significantly higher mean serum CEA than controls (2.4 ± 1.5 vs. 1.5 ± 1.2 ng/mL, P<.0001). Sex did not correlate with CEA levels, while age (Spearman's rho [ρ] = 0.18, P =.002) and HbA1c (ρ = 0.56, P<.0001) did; however, age no longer correlated after correcting for diabetic status. HbA1c was the only variable shown to correlate with CEA in a stepwise linear regression (r = 0.37, P<.001).Conclusion: We observed a statistically significant association between elevated CEA and T2DM, despite average CEA values for both groups being within the reference range. In addition, serum CEA levels correlated positively with HbA1c values.Abbreviations:ADA = American Diabetes AssociationBMI = body mass indexCA 19-9 = carbohydrate antigen 19-9CEA = carcinoembryonic antigenCRP = C-reactive proteinDM = diabetes mellitusHbA1c = glycated hemoglobinJUH = Jordan University HospitalT2DM = type 2 diabetes mellitusρ = Spearman's correlation coefficient     

TEP au 18-FDG et carcinose péritonéale d’origine ovarienne : valeurs diagnostique et pronostique avant chimio-hyperthermie intra-péritonéale (CHIP)

AimEvaluate 18-FDG PET/CT diagnostic and prognostic value before HIPEC.Materials and methodsThis retrospective monocentric study included 38 patients with recurrent (n = 27) or primary (n = 11) ovarian cancer who were blinded reviewed for the presence of peritoneal lesions on PET/CT before HIPEC treatment. The results were compared to surgical and histopathological findings, and to survival curves.ResultsThirty-two patients had peritoneal carcinomatosis based on surgical and histopathological findings, and 19 based on PET. There was no suspicious site of abnormal FGD uptake in the supradiaphragmatic regions. The sensitivity and specificity were respectively 56.2 and 100%. Among the 14 false negative patients, 11 had infracentimetric peritoneal implants, and most of them (n = 13) had chemotherapy before HIPEC. There was significantly more patients treated by chemotherapy in the negative PET group (P = 0.02). Even if the event rate observed was higher in the positive PET group for both event free and overall survival (respectively 68% vs. 64% and 26.3% vs. 17.6%), no significant difference was observed using the survival curves (respectively P = 0.62 and 0.59).ConclusionFDG PET/CT before HIPEC showed excellent specificity and lower sensitivity, due to small peritoneal implants and probably to chemotherapy before HIPEC. No significant prognostic value of FDG PET was observed in our study. FDG PET could be considered as a useful tool for detecting distant metastasis with an impact on therapeutic management.     

Circulating Methylated Septin 9 Nucleic Acid in the Plasma of Patients with Gastrointestinal Cancer in the Stomach and Colon

BACKGROUND: Methylated Septin 9 (mSEPT9) in plasma has recently been suggested as a screening marker for colorectal cancer (CRC) with variable sensitivity. We aimed to determine the usefulness of plasma mSEPT9 for screening CRC and gastric cancer (GC) and its diagnostic role in postoperative CRC patients. METHODS: A total of 350 peripheral blood samples from 101 CRC patients, 153 GC patients, and 96 healthy persons were collected. In addition, we obtained 35 follow-up blood samples from 27 CRC patients after curative radical surgery. Plasma mSEPT9, serum carcinoembryonic antigen (CEA), and serum CA19-9 were evaluated with clinicopathologic features. RESULTS: The sensitivity of plasma mSEPT9 was 36.6% for detecting CRC and 17.7% for detecting GC, and the specificity was 90.6%. During follow-up periods, mSEPT9 showed negative conversion in eight of nine CRC patients (88.9%) whose plasma mSEPT9 had been positive before radical surgery. The patients with plasma mSEPT9 had a tendency of presence of distant metastasis and lower disease-free survival in both CRC and GC. In GC patients, plasma mSEPT9 was more frequently observed in intestinal (23.5%) and mixed type (40.0%) than diffuse type (7.3%; P =.009). Combined analysis of mSEPT9, CEA, and CA19-9 increased the sensitivity for diagnosing GC to 32.7% (P = .002). CONCLUSION: Considering the high incidence of plasma mSEPT9 in intestinal or mixed type GCs similar to CRCs, GC should be examined through the plasma mSEPT9 screening test. In addition, plasma mSEPT9 is proposed as a follow-up marker in CRC patients, but further validation is required.     

Impact of hyperthermic intraperitoneal chemotherapy on Hsp27 protein expression in serum of patients with peritoneal carcinomatosis

Despite the strong rationale for combining cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal carcinomatosis, thermotolerance and chemoresistance might result from heat shock protein overexpression. The aim of the present study was thus to determine whether the heat shock protein 27 (Hsp27), a potential factor in resistance to treatment, could have a higher level in serum from patients under this combined therapy. Patients receiving CRS plus HIPEC for peritoneal carcinomatosis (group 1), patients with cancer or a history of cancer undergoing abdominal surgery (group 2), and patients without malignancies undergoing abdominal surgery (group 3) were included. Hsp27 serum levels were determined before and at different times following CRS and HIPEC using enzyme-linked immunosorbent assay. In group 1 (n = 25), the high Hsp27 levels, observed at the end of surgery compared with before (p < 0.0001), decreased during HIPEC, but remained significantly higher than before surgery (p < 0.0005). In groups 2 (n = 11) and 3 (n = 15), surgery did not significantly increase Hsp27 levels. A targeted molecular strategy, inhibiting Hsp27 expression in tumor tissue, could significantly reduce resistance to the combined CRS plus HIPEC treatment. This approach should be further assessed in a clinical phase I trial.

Optimized Basal-Bolus Insulin Regimens in Type 1 Diabetes: Insulin Glulisine Versus Regular Human Insulin in Combination with Basal Insulin Glargine

ObjectiveTo compare the efficacy and safety of insulin glulisine (GLU), a new rapid-acting insulin analogue, injected 0 to 15 minutes before or immediately after meals, with regular human insulin (RHI), injected 30 to 45 minutes before meals.MethodsPatients with type 1 diabetes (N = 860) received once-daily insulin glargine and subcutaneous injections of either GLU (premeal or postmeal) or premeal RHI in this open-label, randomized, controlled, multicenter, parallel-group, 12-week study.ResultsBaseline to endpoint changes in mean glycated hemoglobin (as A1c equivalents) (A1c) occurred in the premeal GLU, postmeal GLU, and premeal RHI groups (-0.26%, -0.11%, and -0.13%, respectively). The reduction in A1c was greater for the premeal GLU group in comparison with the RHI group (P = 0.02) and the post-meal GLU group (P = 0.006); no significant between-treatment difference was found for postmeal GLU versus RHI. Overall, blood glucose profiles were similar in all 3 treatment groups but were significantly lower for premeal GLU 2-hour postbreakfast measurements (premeal versus postmeal GLU, P = 0.0017; premeal GLU versus RHI, P = 0.0001) and 2-hour postdinner measurements (premeal GLU versus RHI, P = 0.0001; premeal versus postmeal GLU, P = 0.0137). Severe hypoglycemic episodes were comparable for premeal GLU, postmeal GLU, and pre-meal RHI groups (8.4%, 8.4%, and 10.1%, respectively). Body weight increased (+ 0.3 kg) in the RHI and premeal GLU groups; however, weight decreased in the postmeal GLU group (-0.3 kg; between-treatment difference, P = 0.03).ConclusionBetter A1c reductions were obtained with premeal GLU, but postmeal administration of GLU was as safe and effective as premeal GLU or RHI in combination with insulin glargine and was not associated with weight gain.

Prognostic Impact of IPSS-R and Chromosomal Translocations in 751 Korean Patients with Primary Myelodysplastic Syndrome

Chromosomal translocations are rare in myelodysplastic syndrome (MDS) and their impact on overall survival (OS) and response to hypomethylating agents (HMA) is unknown. The prognostic impact of the revised International Prognostic Scoring System (IPSS-R) and for chromosomal translocations was assessed in 751 patients from the Korea MDS Registry. IPSS-R effectively discriminated patients according to leukaemia evolution risk and OS. We identified 40 patients (5.3%) carrying translocations, 30 (75%) of whom also fulfilled complex karyotype criteria. Translocation presence was associated with a shorter OS (median, 12.0 versus 79.7 months, P < 0.01). Multivariate analysis demonstrated that translocations (hazard ratio [HR] 1.64 [1.06–2.63]; P = 0.03) as well as age, sex, IPSS-R, and CK were independent predictors of OS. In the IPSS-R high and very high risk subgroup (n = 260), translocations remained independently associated with OS (HR 1.68 [1.06–2.69], P = 0.03) whereas HMA treatment was not associated with improved survival (median OS, 20.9 versus 21.2 months, P = 0.43). However, translocation carriers exhibited enhanced survival following HMA treatment (median 2.1 versus 12.4 months, P = 0.03). Our data suggest that chromosomal translocation is an independent predictor of adverse outcome and has an additional prognostic value in discriminating patients with MDS having higher risk IPSS-R who could benefit from HMA treatment.     

血清CEA、CA19-9联合CRP在消化道恶性肿瘤的诊断价值分析

摘要 目的：探讨与分析血清CEA、CA19-9联合CRP在消化道恶性肿瘤的诊断价值。方法：2019年8月到2022年5月选择在本院诊治的消化道恶性肿瘤患者150例作为消化道恶性肿瘤组,同期选择在本院体检的健康人群150例作为健康组。采集两组人群的血清癌胚抗原（CEA）、糖类抗原19-9（CA19-9）、C-反应蛋白（CRP）含量,调查患者的病理特征并判断诊断价值。结果：消化道恶性肿瘤组的血清CEA、CA19-9、CRP含量都高于健康组（P<0.05）。消化道恶性肿瘤组的CEA、CA19-9、CRP阳性率为54.7 %、58.7 %、60.7 %,高于健康组的3.3 %、4.0 %、4.7 %（P<0.05）。在消化道恶性肿瘤组中,不同组织学分化、临床分期、淋巴结转移患者的血清CEA、CA19-9、CRP含量对比有差异（P<0.05）。血清CEA、CA19-9联合CRP诊断为阳性113例,在健康组中诊断为阳性3例,血清CEA、CA19-9联合CRP在消化道恶性肿瘤的诊断敏感性与特异性分别为75.3 %（113/150）和98.0 %（147/150）。结论：消化道恶性肿瘤患者多伴随有血清CEA、CA19-9、CRP的高表达,病理特征与血清CEA、CA19-9、CRP含量存在相关性,血清CEA、CA19-9联合CRP在消化道恶性肿瘤的诊断敏感性与特异性都比较好。
