AbstractObjectiveSinonasal malignant melanoma is a relatively rare malignancy with poor prognosis, and effective treatments remain elusive. This analysis aimed to explore whether post-operative radiotherapy conferred any survival advantages in patients with this disease when compared with surgery alone.MethodsPublished studies were identified by searching four electronic databases. The endpoints evaluated were: rates of overall survival, disease-free survival and local control.ResultsTwenty-eight studies including 1392 patients were identified. The results indicated that post-operative radiotherapy led to a significantly better three-year overall survival rate (p= 0.02), and suggested a borderline significant benefit for five-year overall survival (p= 0.05), when compared with surgery alone. However, no statistical advantage was found for disease-free survival, local control or one-year overall survival.ConclusionThis meta-analysis indicated that adjuvant radiotherapy prolonged survival, but showed no benefit for disease-free survival or local control.

Oral squamous cell carcinoma (OSCC) is a common type of cancer characterized by a low survival rate, mostly due to local recurrence and metastasis. In view of the importance of predicting tumor behavior in the choice of treatment strategies for OSCC, several studies have attempted to investigate the prognostic value of tissue biomarkers, including microRNA (miRNA). The purpose of this study was to perform a systematic review and meta-analysis to evaluate the relationship between miRNA expression and survival of OSCC patients. Studies were identified by searching on MEDLINE/PubMed, SCOPUS, Web of Science, and Google Scholar. Quality assessment of studies was performed with the Newcastle-Ottawa Scale. Data were collected from cohort studies comparing disease-free survival and overall survival in patients with high miRNA expression compared to those with low expression. A total of 15 studies featuring 1,200 OSCC samples, predominantly from Asia, met the inclusion criteria and were included in the meta-analysis. Poor prognosis correlated with upregulation of 9 miRNAs (miR-21, miR-455-5p, miiR-155-5p, miR-372, miR-373, miR-29b, miR-1246, miR-196a, and miR-181) and downregulation of 7 miRNAs (miR-204, miR-101, miR-32, miR-20a, miR-16, miR-17, and miR-125b). The pooled hazard ratio values (95% confidence interval) related to different miRNA expression for overall survival and disease-free survival were 2.65 (2.07–3.39) and 1.95 (1.28–2.98), respectively. The results of this meta-analysis revealed that the expression levels of specific miRNAs can robustly predict prognosis of OSCC patients.

Abstract Objective To evaluate local recurrence, metastases, and survival outcomes of `wait and watch’ (WW) strategy and local excision (LE) of tumours, in comparison to the present standard practice of total mesorectal excision (TME) for locally advanced rectal cancers. Data Sources MEDLINE, EMBASE, PubMed databases, and sources of Grey literature. Study Selection Randomised and non-randomised prospective studies, retrospective studies with propensity-score-matched analyses. Data Extraction and Synthesis These were carried out independently by two reviewers. A random-effects methodology was used for meta-analyses. Data was presented keeping with the 27-item PRISMA checklist. Main Outcomes The primary outcomes of interest were local recurrence, distant metastases, disease-free-survival and overall-survival, which were assessed in comparison to those associated with radical surgeries (TME). Results 7 of the 16 studies in the systematic review were included for the quantitative synthesis and meta-analysis. Local recurrence rates were comparable amongst patients in WW group and LE group to those undergoing TME. [Risk ratio (RR) 3.07/1.41; 95% Confidence Interval (CI) 0.86-10.95/0.66-3.01; P = 0.08/P=0.89 respectively]. Rates of distant metastases in the WW group and LE group were comparable to those undergoing TME [RR = 0.71/0.94; 95% CI 0.22-2.30/0.55-1.61; P = 0.56/ P = 0.83 respectively]. The median 3-year disease-free survival among patients undergoing WW, LE procedure, and TME were 88%, 80%, and 78.2% respectively; and the median 3-year overall survival among the three groups were 96%, 93%, and 89.5% respectively. Conclusions and Relevance Organ-preservation strategies appear to be a viable treatment option in the management of rectal-cancers. Further research is warranted to provide stronger levels of evidence on organ-preservation strategies.

Background. Metabolism in the tumor microenvironment can play a critical role in tumorigenesis and tumor aggression. Metabolic coupling may occur between tumor compartments; this phenomenon can be prognostically significant and may be conserved across tumor types. Monocarboxylate transporters (MCTs) play an integral role in cellular metabolism via lactate transport and have been implicated in metabolic synergy in tumors. The transporters MCT1 and MCT4 are regulated via expression of their chaperone, CD147.Methods. We conducted a meta-analysis of existing publications on the relationship between MCT1, MCT4, and CD147 expression and overall survival and disease-free survival in cancer, using hazard ratios derived via multivariate Cox regression analyses.Results. Increased MCT4 expressions in the tumor microenvironment, cancer cells, or stromal cells were all associated with decreased overall survival and decreased disease-free survival (p<0.001for all analyses). Increased CD147 expression in cancer cells was associated with decreased overall survival and disease-free survival (p<0.0001for both analyses). Few studies were available on MCT1 expression; MCT1 expression was not clearly associated with overall or disease-free survival.Conclusion. MCT4 and CD147 expression correlate with worse prognosis across many cancer types. These results warrant further investigation of these associations.

Background: The pretreatment prognostic nutritional index has been considered a potential prognostic biomarker in patients with non-small cell lung cancer (NSCLC), but this remains controversial. Therefore, we performed a meta-analysis to systematically assess the prognostic value of the prognostic nutritional index in patients with NSCLC. Methods: We systematically searched PubMed, EMBASE, Web of Science, and CNKI. The hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs) were used to evaluate the link between the prognostic nutritional index and the oncological outcomes of patients with NSCLC, including overall survival, disease-free survival/recurrence-free survival, and progression-free survival. Results: Fifteen studies were included in this meta-analysis. Twelve of these studies explored the association between the prognostic nutritional index and the overall survival of patients with NSCLC. Our pooled analysis indicated that a low prognostic nutritional index was significantly related to adverse overall survival (HR 1.61; 95% CI 1.44, 1.81; P < 0.001). Our results also showed that the prognostic nutritional index was a negative predictor for disease-free survival/recurrence-free survival, and progression-free survival in patients with NSCLC. Conclusion: Our meta-analysis demonstrated that there was a close association between the prognostic nutritional index value and prognosis in NSCLC patients and that the prognostic nutritional index may act as a useful prognostic biomarker in NSCLC patients.

Abstract Background The aim of this study is to compare the outcome of patients with adenocarcinoma of the distal oesophagus (AEG Type I) treated with perioperative chemotherapy or neoadjuvant chemoradiation. Methods A retrospective analysis of eligible patients from four Austrian centers was conducted. All patients with AEG type I treated between January 2007 and October 2017 with chemotherapy (EOX-protocol) or chemoradiation (CROSS-protocol, or 5-FU/Cisplatin), followed by oesophagectomy were included in the study. Primary outcomes overall survival, and disease free survival as well as secondary outcomes, achievement of pathological complete response pCR (ypT0N0M0) or downstaging of T- or N-stage were analyzed. Primary outcomes were calculated by the Kaplan-Meier-method. Results Data of 117 patients were analyzed, 59 received chemoradiation (50/59 CROSS and 9/59 5-FU/Cisplatin) and 58 patients received perioperative chemotherapy (EOX). Complete data at time of submission were available in 40 patients in the chemoradiation group and in 37 patients in the chemotherapy group. The median follow-up time in the chemoradiation group was 13,0 months (CI 95%: 11,0–15,0) and in the chemotherapy group 45,0 months (CI 95%: 28,8–61,3). Overall survival rate in the EOX group after ½, 1, 3 and 5 years was 92%, 83%, 63% and 34%. So far long term data are not available after chemoradiation, after ½ year overall survival was 84% and after one year 60%. Disease free survival rate in the EOX group after ½, 1, 3 and 5 years was 91%, 81%, 54% and 32%, in the chemoradiation group after ½ and one year 80% and 50%. A significant difference was found in the pathological complete response (pCR) rate, it was achieved in 19% of patients after chemoradiation and in 3% after chemotherapy (P = 0000). Conclusion Concerning major response of the primary tumor there are clear advantages for chemoradiation. In regards to systemic tumor control there seems a tendency in favor for chemotherapy.

IntroductionMultidisciplinary treatment strategy involving adjuvant radiotherapy for advanced vulvar cancer could be useful in offering the best personalized clinical approach. In 2013, the VULvar CANcer Multi-Disciplinary Team (Vul.Can MDT) was set up in our institution, in order to share knowledge and expertise, high-quality diagnosis, and evidence-based decision making in the context of personalized medicine. The aim of this observational study was to report on our series of vulvar cancer patients managed postoperatively with radiotherapy within the framework of a formal multidisciplinary tumor board.MethodsCoupling surgical and oncological international guidelines with “case-by-case” discussions, a multi-specialist consensus was progressively reached and internal recommendations were developed and introduced in the daily routine. Data from vulvar cancer patients who underwent primary surgery and adjuvant radiotherapy throughout a 5-year period were retrospectively collected. Actuarial local control was the primary endpoint, while secondary end-points were acute and late toxicities, disease-free survival, and overall survival. Toxicity was evaluated according to the Common Toxicity Criteria Adverse Event v 4.0 scale.ResultsThe analysis included 35 patients with squamous vulvar cancer treated with adjuvant radiotherapy±chemotherapy, from April 2013 to September 2017. Median age was 70 years (range 18–87), all patients underwent surgery followed by concomitant chemoradiation (45.7%) or radiotherapy alone (54.3%). The median prophylactic dose on lymphatic drainage was 45 Gy, while positive nodes and perineal area received 51.2 Gy and 52.6 Gy, respectively. Chemotherapy involved the cisplatin-based regimen (45.7%)±5-fluorouracil (37.1%). Median follow-up was 32 months (range 6–72): the 24-months local control, disease-free survival, and actuarial overall survival rates were 88.6%, 82.0%, and 91.0%, respectively. Low rates of severe acute (12%) and late (3%) toxicities occurred.DiscussionThe outcomes of this series support the benefit of a multidisciplinary personalized approach in the management of vulvar cancer.

3548 Background: Colon cancer is potentially curable by surgery in the early stages of the disease. Adjuvant chemotherapy improves disease-free and overall survival in patients with stage III disease, but the magnitude of benefit in stage II colon cancer is less clear. A previous Cochrane systematic review and meta-analysis (SR/MA) found improved disease-free, but not overall survival (Figueredo et al., 2008). An updated SR/MA was performed to determine the effects of adjuvant chemotherapy on disease-free and overall survival in patients with stage II colon cancer. Methods: Relevant databases (MEDLINE, EMBASE, and Cochrane) were independently searched by all authors, using the same search strategy employed in the original study (1/1988 to 9/2012). Randomized trials containing data on stage II colon cancer patients undergoing adjuvant 5-fluorouracil (5FU) chemotherapy versus observation were included. Pooled results were expressed as hazard ratios (HR) whenever possible, or risk ratios (RR), with 95% confidence intervals (95%CI) using a random effects model. Results: Seven studies were identified, and included in the final SR/MA. Six of the 7 studies were included in the disease-free survival analysis (n=4587). Adjuvant 5FU was associated with better disease-free survival (RR 0.84 (95%CI 0.75-0.94)). All 7 studies (n=5353) were included in the overall survival analysis showing an improvement with adjuvant 5FU (HR 0.87 (95%CI 0.78-0.97)). There was no evidence of heterogeneity across the studies (I2 = 0% for all analyses). Conclusions: In stage II colon cancer, adjuvant 5FU chemotherapy statistically improves both disease-free and overall survival. Our SR/MA demonstrates, for the first time, an overall survival advantage with adjuvant chemotherapy in stage II colon cancer.

4585 Background: Adjuvant trials aim to integrate systemic therapy earlier to increase cure rates over surgery alone. Overall survival (OS) is a critical endpoint for these studies but requires long durations to events and significant patient resources. We explored the potential use of disease-free survival (DFS) as an intermediate readout for OS in the adjuvant setting for localized renal cell carcinoma (RCC). Methods: We performed a systematic literature review following the PRISMA guidelines. Inclusion criteria required randomized controlled trials (RCT) for adjuvant systemic therapy in localized RCC, which reported on both DFS and OS. Data on hazard ratio (HR) and 5-year event-free rate from Kaplan-Meier estimates were extracted. We performed a trial level meta-analysis and correlated these estimates for OS and DFS, weighted by the number of DFS events. R-square > 0.7 would indicate a strong correlation and potential for surrogacy. Results: Thirteen RCTs encompassing 6,473 patients treated with various forms of systemic therapy were eligible for the analyses. Minimum follow-up was 40 months. There was a moderate correlation between 5-year DFS and 5-year OS rates (R-square = 0.49, 95% CI:0.15-0.68) and between treatment effects as measured by DFS and OS hazard ratios (R-square = 0.44, 95% CI:0.00-0.69). Conclusions: Across trials of adjuvant systemic therapy for localized RCC, we observed a moderate correlation between 5-year DFS and OS rates and between treatment effects (HRs) on these endpoints. Further granularity may be achieved using individual patient data to assess different and earlier time points for surrogacy than are commonly reported. [Table: see text]

Purpose To develop a systematic review that would address the following question: Should patients with stage II colon cancer receive adjuvant therapy? Methods A systematic review was undertaken to locate randomized controlled trials comparing adjuvant therapy to observation. Results Thirty-seven trials and 11 meta-analyses were included. The evidence for stage II colon cancer comes primarily from a trial of fluorouracil plus levamisole and a meta-analysis of 1,016 patients comparing fluorouracil plus folinic acid versus observation. Neither detected an improvement in disease-free or overall survival for adjuvant therapy. A recent pooled analysis of data from seven trials observed a benefit for adjuvant therapy in a multivariate analysis for both disease-free and overall survival. The disease-free survival benefits appeared to extend to stage II patients; however, no P values were provided. A meta-analysis of chemotherapy by portal vein infusion has also shown a benefit in disease-free and overall survival for stage II patients. A meta-analysis was conducted using data on stage II patients where data were available (n = 4,187). The mortality risk ratio was 0.87 (95% CI, 0.75 to 1.01; P = .07). Conclusion There is preliminary evidence indicating that adjuvant therapy is associated with a disease-free survival benefit for patients with stage II colon cancer. These benefits are small and not necessarily associated with improved overall survival. Patients should be made aware of these results and encouraged to participate in active clinical trials. Additional investigation of newer therapies and more mature data from the presently available trials should be pursued.

Abstract Background: In clinical work, it has been increasingly found that the prognosis is still very different even for esophageal cancer (EC) patients with the same TNM stage. Tumor length has been analysed as a possible independent prognostic factor in many studies, but no unanimous conclusion has been reached. Therefore, this review used a meta-analysis to evaluate the association between tumor length and prognosis in EC patients.Methods: A systematic search for relevant articles was performed in PubMed, Web of Science, and Embase. Hazard ratios (HRs) and 95% confidence intervals (CIs) were used as effective measures to estimate the correlation between tumor length and prognosis, including overall survival, disease-free survival, progression-free survival, disease-specific survival, and cancer-specific survival. STATA 15.0 software was used to perform the meta-analysis and the data synthesis.Results: Finally, 41 articles with 28,973 patients were included in our study. The comprehensive statistical results showed that long tumors are an independent prognostic parameter associated with poor overall survival (OS) (HR=1.30; 95% CI: 1.21-1.40, p<.001) and disease-free survival (DFS) (HR=1.38; 95% CI: 1.18-1.61, p<.001) in EC patients. Subgroup analyses also suggested a significant correlation between long tumors and poor OS. Sensitivity analysis and publication bias evaluation confirmed the reliability and stability of the results. Similar results were obtained in the analyses of progression-free survival (PFS), disease-specific survival (DSS), and cancer-specific survival (CSS).Conclusion: The results of this meta-analysis showed that long tumors were related to poor OS, DFS, PFS, DSS and CSS in EC patients. Tumor length might be an important predictor of prognosis in EC patients, and it can be used as an independent staging index. Further well-designed and large-scale prospective clinical studies are needed to confirm these findings.
