Abstract Purpose Neutrophil-to-lymphocyte ratio (NLR) has been reported to be associated with treatment outcomes in various cancers; however, the optimal timing to measure NLR is unclear. In this study, “average-NLR” was newly devised, which reflects the NLR throughout the course of radiotherapy, and its usefulness was assessed for stage III non-small cell lung cancer (NSCLC) patients treated with chemoradiotherapy. Materials and methods A total of 111 patients who received definitive chemoradiotherapy for unresectable stage III NSCLC were reviewed. Patient/tumor-related factors, treatment-related, and NLR-related factors (average-NLR, pre- and post-radiotherapy NLR, NLR-nadir, NLR-maximum) were assessed using univariate and multivariate analyses. Results The median follow-up period was 43.8 months among the survivors. In the multivariate analysis, average-NLR and post-radiotherapy NLR were significant factors for the overall survival (OS) (p = 0.016 and 0.028) and distant failure (DF) (p = 0.008 and 0.040). For the patients with low, intermediate, and high average-NLR, the median OS was 41.2, 37.7, and 14.8 months, respectively, and the median DF free time was 52.5, 13.5, and 8.9 months, respectively. Conclusion Average-NLR and post-radiotherapy NLR were significant factors for the OS and DF. Average-NLR, which was available immediately after the completion of chemoradiotherapy, seemed to be helpful for treatment decisions.

Abstract Objective To quantify the association of cancer treatment delay and mortality for each four week increase in delay to inform cancer treatment pathways. Design Systematic review and meta-analysis. Data sources Published studies in Medline from 1 January 2000 to 10 April 2020. Eligibility criteria for selecting studies Curative, neoadjuvant, and adjuvant indications for surgery, systemic treatment, or radiotherapy for cancers of the bladder, breast, colon, rectum, lung, cervix, and head and neck were included. The main outcome measure was the hazard ratio for overall survival for each four week delay for each indication. Delay was measured from diagnosis to first treatment, or from the completion of one treatment to the start of the next. The primary analysis only included high validity studies controlling for major prognostic factors. Hazard ratios were assumed to be log linear in relation to overall survival and were converted to an effect for each four week delay. Pooled effects were estimated using DerSimonian and Laird random effect models. Results The review included 34 studies for 17 indications (n=1 272 681 patients). No high validity data were found for five of the radiotherapy indications or for cervical cancer surgery. The association between delay and increased mortality was significant (P<0.05) for 13 of 17 indications. Surgery findings were consistent, with a mortality risk for each four week delay of 1.06-1.08 (eg, colectomy 1.06, 95% confidence interval 1.01 to 1.12; breast surgery 1.08, 1.03 to 1.13). Estimates for systemic treatment varied (hazard ratio range 1.01-1.28). Radiotherapy estimates were for radical radiotherapy for head and neck cancer (hazard ratio 1.09, 95% confidence interval 1.05 to 1.14), adjuvant radiotherapy after breast conserving surgery (0.98, 0.88 to 1.09), and cervix cancer adjuvant radiotherapy (1.23, 1.00 to 1.50). A sensitivity analysis of studies that had been excluded because of lack of information on comorbidities or functional status did not change the findings. Conclusions Cancer treatment delay is a problem in health systems worldwide. The impact of delay on mortality can now be quantified for prioritisation and modelling. Even a four week delay of cancer treatment is associated with increased mortality across surgical, systemic treatment, and radiotherapy indications for seven cancers. Policies focused on minimising system level delays to cancer treatment initiation could improve population level survival outcomes.

Abstract   During esophagectomy for cancer, there is no consensus if prophylactic thoracic duct ligation (TDL), with or without thoracic duct resection (TDR), could influence the perioperative outcomes and long-term survival. This systematic review and meta-analysis compared patients who went through esophagectomy associated or not to ligation or resection of the thoracic duct. Methods A systematic review was conducted in PubMed, Embase, Cochrane Library Central and Lilacs (BVS). The inclusion criteria were: (1) studies that compare thoracic duct ligation, with or without resection, and non-thoracic duct ligation; (2) involve adult patients with esophageal cancer; (3) articles that analyses the outcomes—perioperative complications, perioperative mortality, chylothorax development and overall survival; (4) only clinical trials and cohort were accepted. A 95% confidence interval (CI) was used, and random-effects model was performed. Results Fifteen articles were selected, comprising 6,249 patients. TDL did not reduce the risk for chylothorax (Risk difference [RD]: -0.01; 95%CI: −0.02, 0.00). Also, TDL did not influence the risk for complications (RD: -0.02; 95%CI: −0.11, 0.07); mortality (RD: 0.00; 95%CI: −0.00, 0.00); and reoperation rate (RD: -0.01; 95%CI: −0.02, 0.00). TDR was associated with higher risk for postoperative complications (RD: 0.1; 95%CI 0.00, 0.19); chylothorax (RD: 0.02; 95%CI 0.00, 0.03). Both TDL and TDR did not influence the overall survival rate (TDL: HR: 1.17; 95%CI: 0.86, 1.48; and TDR: HR: 1.16; 95%CI: 0.8, 1.51). Conclusion Thoracic duct obliteration with or without its resection during esophagectomy does not change long term survival. Nonetheless, TDR increased the risk for postoperative complications and chylothorax.

Objective: This study aimed to assess the effect of anti-programmed cell death-1/programmed cell death-ligand-1 (PD-1/PD-L1) agents compared with second-line therapy in patients with metastatic or locally advanced urothelial bladder carcinoma following previous platinum-containing chemotherapy.Material and Methods: We systematically searched three electronic databases. The protocol of the study was registered in Prospero (CRD42019142494). Using the Grading of Recommendations Assessment, Development, and Evaluation approach, the certainty of evidence (CoE) was estimated.Results: The search results initially found 8168 publications. For qualitative synthesis, two publications were included. Pooled results indicated that patients treated with anti-PD-1/PD-L1 agents had significantly prolonged overall survival (hazard ratio (HR) 0.80; 95% confidence interval (CI) 0.7-0.9; I2 21.0%; moderate CoE). According to positive PD-L1 expression, PD-1/PD-L1 inhibitors had significantly more survival than chemotherapy (HR 0.75; 95% CI 0.5-0.9, I2 57.0%, low CoE). Furthermore, there was no significant difference in adverse events (AE) between the anti-PD-1/PDL1 agents and second-line chemotherapy (risk ratio 0.68; 95% CI 0.3-1.4; I2 97.0%, low CoE).Conclusion: The present meta-analysis and systematic review provide strong evidence that anti-PD-1/PD-L1 agents could improve overall survival and have similar results in AEs compared with second-line chemotherapy. Further studies will confirm the power of immunotherapy for the treatment of metastatic or locally advanced urothelial bladder carcinoma.
