BackgroundRecently, several studies observed that locally advanced cervical carcinoma with negative excision repair crross-complementation group one enzyme expression has better outcomes in cisplatin-based chemotherapy or chemoradiotherapy than carcinoma with positive excission repair cross-complementation group one enzyme expression. In this meta-analysis, we quantitatively evaluated the prognostic value of excission repair cross-complementation group one enzyme expression in locally advanced cervical carcinoma patients receiving platinum-based chemotherapy or chemoradiotherapy.MaterialsA systematic search for relevant studies was conducted in the PubMed, Cochrane Library, EMBASE and Medline databases. Fixed- or random-effects models were used for pooled analysis. The endpoints were overall survival and disease-free survival () reported as ORs and 95% CIs. The effects of excission repair cross-complementation group one enzyme expression on the clinicopathological parameters were measured by the pooled ORs and their 95% CIs.ResultsEight studies (612 patients in total) satisfied the inclusion criteria. Negative/low excission repair cross-complementation group one enzyme expression was significantly associated with better overall survival (OR, 1.92; 95% CI, 1.22 to 3.05; P = 0.005) and disease-free survival (OR, 5.77; 95% CI, 1.90 to 17.54; P = 0.002). Additionally, there were significant associations between excission repair cross-complementation group one enzyme expression and lymph node metastasis (OR, 2.57; 95% CI, 1.28 to 5.16; P = 0.008).ConclusionsThis meta-analysis suggested that pretreatment excission repair cross-complementation group one enzyme expression might be a useful biomarker to predict prognoses for locally advanced cervical carcinoma patients receiving platinum-based chemotherapy or chemoradiotherapy.

The objective of this study was to evaluate the influence of cisplatin dose upon 3-year overall and disease-free survival rate of patients with advanced cervical cancer treated with concurrent chemoradiotherapy with weekly cisplatin. Seventy-three patients with stage IIB – IVA cervical carcinoma were treated with pelvic (or pelvic + paraaortic) externalbeam radiotherapy, high-dose rate brachytherapy and concomitant chemotherapy with weekly cisplatin of 40 mg/m2 in the time period form January 2000 to December 2006 at our department. The 3-year overall survival and disease-free suvival rates were evaluated with regard to the number of cisplatin cycles applied during the external radiotherapy. Only twentyeight patients received the intended five doses of chemotherapy. The most frequent cause of chemotherapy delay was the acute hematological toxicity with leukopenia. The 3-year overall survival was 71 % and the 3-year disease-free survival was 61 %. Survival analyses didn’t prove a statistically significant influence of cisplatin dose upon 3-year survival in cervical carcinoma patients treated by exclusive chemoradiation with weekly cisplatin.

Advanced Cervical Carcinoma

Introduction:Carcinoma cervix is the second most common cancer among women in India. Carcinoma cervix is associated with many risk factors such as multi parity, early age at marriage, early age at coitus and the most important basic cause is poor socioeconomic status, illiteracy, lack of proper self-hygiene, lack of awareness of screening programs and treatment modalities. The main objective of this study is to analyze various outcomes following treatment of locally advanced carcinoma cervix and also to determine the causes of treatment failure so as to improve disease free survival, progression free survival and overall survival. Materials And Methods: A retrospective study was conducted among 191 locally advanced cervical carcinoma patients treated in the Department of Radiotherapy, Stanley Medical College and Hospital, Chennai during the period between 2015 and 2019. Various parameters of our study included age distribution, chief complaints at presentation, histopathological types and grades, staging, type of treatment, details of brachytherapy, response assessment and follow up. Results: Majority of them belong to stage II(50%) followed by stage III (41%). 14 patients belong to stage IV and only 4 patients belong to stage I. Among them 102 patients (53.4%) showed complete response and 34 patients (17.8%) showed partial response. Discussion: Most of the patients were in 4th and 5th decade which is very close to TNCRPregistry. Stage grouping of patients is considered most signicant in assessing the outcome of the treatment wherein it was found necessary to identify and present the symptoms at early stage to fasten the treatment and aim at complete cure. Conclusion: This study brings a clear picture of the possible reasons for treatment failure in locally advanced cervical carcinoma and highlights necessary steps to be implemented in improving infrastructure facilities in Government hospitals that would result in better treatment for poor patients with maximum benets.

4066 Background: The benefits of adjuvant chemo-radiotherapy (ChRT) over chemotherapy (Ch) for resectable gastric cancer are currently unclear. We performed a systematic review and meta-analysis (direct and indirect) of published randomized controlled trials (RCT) to compare the effects of adjuvant chemo-radiotherapy with chemotherapy on overall and disease-free survival for patients with resectable gastric cancer. Methods: We searched MEDLINE and CENTRAL from the date of inception and annual meeting proceedings of ASCO and ASTRO from 1999 to November 2012 for RCTs comparing adjuvant ChRT with Ch, adjuvant ChRT with surgery alone and adjuvant Ch with surgery alone. The primary outcome was overall survival (OS); secondary outcomes included disease-free survival (DFS) and toxicity. Hazard ratios (HR), confidence intervals (CI) and p values (p) were estimated with fixed effects models using Revman 5.1. Results: We found five trials comparing adjuvant ChRT with Ch (n = 1110), three trials comparing adjuvant ChRT with surgery alone (n = 651) and 31 trials comparing adjuvant Ch with surgery alone (n = 8273). Meta-analysis of direct comparison trials showed that adjuvant ChRT significantly improved both OS (HR 0.79, 95% CI 0.64-0.98, p = 0.03) and DFS (HR 0.76, 95% CI 0.64-0.92, p = 0.004) when compared with Ch. Subgroup analyses showed that the effects on OS and DFS were similar regardless of use of D2 nodal dissection, intensity modulated radiotherapy techniques, fluorouracil or platinum-based chemotherapy. There were no significant differences in toxicity between the two groups. The results for the direct and indirect comparisons were statistically consistent. Conclusions: There was a significant survival benefit of adjuvant chemo-radiotherapy over chemotherapy, with no increase in toxicity for patients with resected gastric cancer. Future efforts should also focus on predictive markers, and toxicity or quality-of-life assessments, to individualize adjuvant therapy and optimize the therapeutic ratio.

Abstract Introduction Oesophagectomy is being increasingly performed in an ageing population that is observing a concomitant growth in the life expectancy. However, the risks are poorly quantified, and this study aims to review current evidence to further quantify the postoperative of oesophagectomy in the elderly population compared to younger patients. Methods A systematic electronic search was conducted for studies reporting oesophagectomy in the elderly population. Meta-analysis was performed using random-effects modelling to compute odds ratios (OR) and 95% confidence intervals (CI). Primary outcome was overall complications and secondary outcomes included anastomotic leaks, cardiac complications, pulmonary complications, overall and disease-free survival. Meta-regression was performed to identify study-, hospital- and patient-level factors confounding study findings. Results This review included 37 eligible studies involving 61,723 patients. Increasing age was significantly associated with increased rates of overall complications (OR: 1.67, CI 95%: 1.42 – 1.97), cardiac complications (OR: 1.62, CI 95%: 1.10 – 2.40), pulmonary complications (OR: 1.44, CI 95%: 1.11 – 1.87) and decreased 5-year overall survival (OR: 1.36, CI 95%: 1.11 – 1.66) and 5-year disease-free survival (OR: 1.66, CI 95%: 1.40 – 1.97). Rates of anastomotic leaks showed no difference between elderly and younger patients (OR: 1.06, CI 95%: 0.71 – 1.59). Conclusion Postoperative outcomes such as overall complications, 5-year overall survival and disease-free survival appear to significantly worse in all age cut-offs in this meta-analysis. Sarcopenia and frailty act as better predictors of postoperative outcomes than chronological age. This study confirms the preconceived suspicions of increased risks in elderly patients following oesophagectomy and will aid future pre-operative counselling and informed consent.

The C-reactive protein-to-albumin ratio is a proven prognostic predictor of nasopharyngeal carcinoma. However, the role of the C-reactive protein-to-albumin ratio in other head and neck cancers remains unclear. This meta-analysis explored the prognostic value of the C-reactive protein-to-albumin ratio in head and neck cancers. A systematic search was conducted. Outcomes of interest included overall survival, disease-free survival, and distant metastasis–free survival. The hazard ratio with 95% confidence interval was pooled using a random-effects model. A total of 11 publications from the literature were included, allowing for the analysis of 7080 participants. Data pooling demonstrated that pretreatment C-reactive protein-to-albumin ratio had a hazard ratio of 1.88 (95% CI: 1.49−2.37, p < 0.001) for predicting overall survival, 1.91 (95% CI: 1.18−3.08, p = 0.002) for disease-free survival, and 1.46 (95% CI: 1.08−1.96, p = 0.001) for distant metastasis–free survival. Subgroup analysis showed that the C-reactive protein-to-albumin ratio is a significant prognostic marker for various head and neck cancers. An elevated pretreatment C-reactive protein-to-albumin ratio predicts a worse prognosis for patients with head and neck cancers. Therefore, the C-reactive protein-to-albumin ratio could serve as a potential prognostic biomarker facilitating treatment stratification.

Aim: To assess the prognostic value of the pretreatment serum γ-glutamyltranspeptidase (GGT) level in patients with primary liver cancer (PLC). Methods: Relevant studies were systematically searched online on Web of Science, PubMed, and Embase databases published until 9 October 2018. The end points were overall survival (OS), recurrence-free survival (RFS), and disease-free survival (DFS). Meta-analysis was conducted using hazard ratio (HR), and its 95% confidence interval (CI) as effect measure. Results: A total of 33 eligible studies with 9238 patients with PLC were included in this meta-analysis. The synthesized analysis showed that that higher serum GGT level was significantly related to poorer OS (HR: 1.79, 95% CI: 1.66–1.93, P<0.01), RFS (HR: 1.60, 95% CI: 1.46–1.77, P<0.01), and DFS (HR: 1.52, 95% CI: 1.33–1.73, P<0.01) of patients with PLC. Subgroup analyses demonstrated that the negative prognostic impact of higher serum GGT level on OS and RFS was still of significance regardless of ethnicity, pathological type, sample size, cut-off value, first-line treatment, and analysis type. Conclusion: The pretreatment serum GGT might be a predictive factor of poor prognosis for PLC patients.

Background The aim of this study was to conduct a meta-analysis comparing the safety and feasibility of laparoscopic versus open resection for gastric gastrointestinal stromal tumors (GISTs) larger than 5 cm. Method We searched the Cochrane Library, PubMed, and Embase for relevant articles. Randomized and nonrandomized clinical trials were identified and included in this study. Searching for related articles on large GIST (>5 cm) for laparoscopic resection (laparoscopic group [LAPG]) and open resection (open group [OG]), RevMan 5.3 was used for data analysis, comparing 2 groups of operation time, intraoperative blood loss, complications, length of hospital stay, recurrence rate, disease-free survival, and overall survival. Results Seven studies including 440 patients were identified for the meta-analysis. Meta-analysis revealed that LAPG had less bleeding, shorter postoperative hospital stay, and a better 5-year disease-free survival. There was no significant difference between LAPG and OG in operation time, postoperative complications, recurrence rate, and overall survival. Conclusion Laparoscopic resection of large (>5 cm) GIST is safe and feasible and has the advantages of less intraoperative blood loss and fast postoperative recovery, with a good outcome in the recent oncology.

BackgroundTumor-stroma ratio (TSR) is a promising new prognostic predictor for patients with rectal cancer (RC). Although several studies focused on this pathologic feature, results from those studies were still inconsistent.MethodsThis research aimed to estimate the prognostic values of TSR for RC. A search of PubMed, EMBASE, and Web of Science was carried out. A meta-analysis was performed on disease-free survival, cancer-specific survival, and overall survival in patients with RC.ResultsThe literature search generated 1,072 possible studies, of which a total of 15 studies, involving a total of 5,408 patients, were eventually included in the meta-analysis. Thirteen of the 15 articles set the cutoff for the ratio of stroma at 50%, dividing patients into low-stroma and high-stroma groups. Low TSR (rich-stroma) was significantly associated with poorer survival outcome. (DFS: HR 1.54, 95% CI 1.32–1.79; OS: HR 1.52 95% CI 1.34–1.73; CSS: HR 2.05 95% CI 1.52–2.77).ConclusionPresent data support TSR to be a risk predictor for poor prognosis in RC patients.
