Potential involving throughout vivo- along with vitro-cultured entomopathogenic nematodes to infect Lobesia vanillana (Lepidoptera: Tortricidae) under research laboratory problems.
Gross tumor volume was the only significant prognostic factor in both univariate and multivariable analyses. CONCLUSION We found that radical definitive re-irradiation may lead to one-fifth long-term survivors of patients with OR after previous curative radiotherapy for ESCC, and the gross tumor volume was the only significant prognostic factor for these patients. Randomized controlled trials should be considered to compare radical re-irradiation with the current standard of care (systemic therapy) for this population. BACKGROUND/AIM The effect of renal dysfunction on the toxicity and efficacy of oxaliplatin remains unclear. We investigated the association between creatinine clearance (Ccr), a marker of renal function, and the toxicity and efficacy of oxaliplatin in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS Patients with mCRC who received oxaliplatin-based chemotherapy as first-line treatment were included in this study. Primary outcome was peripheral neuropathy (Grade ≥2), while secondary outcomes included neutropenia (Grade ≥3), thrombocytopenia (Grade ≥2) and overall survival (OS). RESULTS A total of 145 patients with mCRC were eligible. Incidence rates of peripheral neuropathy (Grade ≥2), neutropenia (Grade ≥3) and thrombocytopenia (Grade ≥2) were 30.3%, 37.2% and 16.6%, respectively, and median OS was 29.1 months. Cox proportional hazards analysis indicated that there was no significant relationship between Ccr and any adverse event, or between Ccr and OS. CONCLUSION Dose reduction of oxaliplatin based on Ccr is not recommended in patients with mCRC. BACKGROUND/AIM The clinical significance of surgery for secondary small intestinal non-Hodgkin's lymphomas (NHL) remains unknown. This study aimed to investigate the efficacy of resection for both primary and secondary small intestinal NHL. PATIENTS AND METHODS Twenty patients with small intestinal lymphoma who underwent surgical resection at our Institute between 2009 and 2017 were retrospectively evaluated. The clinicopathological and surgery-related factors were reviewed. We also analyzed their surgical outcomes such as postoperative complications, perforation rate, and overall survival (OS). RESULTS In total, 13 (65%) and 7 (35%) patients had primary and secondary lymphomas, respectively. A total of 70% of patients were diagnosed with aggressive-type lymphomas. A total of 15 (75%) patients had Lugano system stage IV. Only one (5%) patient experienced postoperative grade II deep vein thrombosis and pulmonary embolism. The 3-year OS rate after surgery was 59.6%. CONCLUSION Surgical resection prior to chemotherapy is a feasible and safe therapeutic strategy for small intestinal NHL. BACKGROUND Several immune-inflammatory markers are associated with cancer progression. The purpose of the present study was to clarify the influence of the preoperative C-reactive protein-to-albumin ratio (CRP/ALB ratio) on survival of patients with esophageal cancer and recurrence after curative resection. PATIENTS AND METHODS The preoperative CRP/ALB ratio was evaluated in 122 patients who underwent radical resection for esophageal cancer from 2005 to 2018. Cytoskeletal Signaling inhibitor The correlations between the CRP/ALB ratio and cancer-specific overall (OS), recurrence-free (RFS) survival and the clinicopathological status were analyzed. RESULTS The optimal cut-off value of the CRP/ALB ratio determined using receiver operating characteristic curve analysis was 0.04. Patients were divided into two groups based on this cut-off value the low CRP/ALB group (n=59) and the high CRP/ALB group (n=50). The OS rate at 5 years after surgery was significantly lower in the group with high CRP/ALB at 40.5% whilst it was 63.5% in the low CRP/ALB group (p=0.005). The corresponding RFS rates at 5 years after surgery were 32.5% and 48.3%, respectively, which was a statistically significant difference (p=0.007). A multivariate analysis showed that a high CRP/ALB ratio was a significant independent risk factor for poorer cancer-specific OS and RFS. CONCLUSION The preoperative CRP/ALB ratio was a strong prognostic marker for patients with esophageal cancer. The surgical strategy, including procedure and perioperative care should be carefully planned for patients with a high CRP/ALB ratio. BACKGROUND The aim of the present study was to evaluate the clinical impact of the perioperative use of antiplatelet/anticoagulation therapy for postoperative bleeding after esophagectomy for esophageal cancer. PATIENTS AND METHODS Patients were selected from the medical records of consecutive patients who were diagnosed with primary esophageal adenocarcinoma or squamous cell carcinoma and who underwent complete resection at Yokohama City University from January 2005 to September 2018. The patients were divided into the antiplatelet/anticoagulation treatment group and the non-treatment group. We compared the safety and feasibility of esophagectomy between two groups. RESULTS One hundred and twenty-two patients underwent esophagectomy for esophageal cancer and were analyzed in the present study. Among them, 18 (14.8%) received anti-thrombotic therapy (anticoagulation group). The incidence of postoperative bleeding in patients overall was 8.2% (10/122). The incidence of postoperative bleeding in the anticoagulation group was 22.2% (4/18), while that in the non-anticoagulation group was 5.8% (6/104). Preoperative anticoagulation therapy was identified as a significant independent risk factor for postoperative bleeding (hazard ratio=4.673, 95% confidence interval=1.170-18.519; p=0.029). CONCLUSION The perioperative use of anti-thrombotic therapy was a significant risk factor for postoperative bleeding after esophagectomy for esophageal cancer. Thus, when patients receive perioperative antiplatelet/anticoagulation treatment, careful attention is required after esophagectomy due to their increased risk of postoperative bleeding. BACKGROUND/AIM The prognosis of gastric cancer with para-aortic or bulky lymph node metastases is poor, but the JCOG 0405 study showed relatively good outcomes of neoadjuvant chemotherapy and gastrectomy with para-aortic lymph node dissection. We investigated the prognostic factors for this treatment. PATIENTS AND METHODS Twenty patients who underwent gastrectomy and para-aortic lymph node dissection after chemotherapy were enrolled from two institutions. The prognostic factors for overall survival were retrospectively analysed using Cox's proportional hazard models. RESULTS The univariate analyses revealed that ypN (3/0-2, p=0.001), ypM1 (para-aortic LYM) (yes/no, p=0.03), histological response (Grade0-1b/2-3, p=0.02), and adjuvant chemotherapy (no/yes, p=0.02) were significant prognostic factors, whereas multivariate analysis revealed ypN and absence of adjuvant chemotherapy to be independent prognostic factors. CONCLUSION Posttreatment nodal status may be the best surrogate marker for gastric cancer with gastrectomy and para-aortic lymph node dissection after neoadjuvant chemotherapy.
