To investigate literature-based evidence regarding progression-free survival (PFS) as an early efficacy endpoint in patients with resectable esophageal or gastroesophageal junction (GEJ) cancer receiving neoadjuvant therapy, this study identified large-scale randomized controlled trials (RCTs) with strict quality control. Twenty-four RCTs involving 7,514 patients were included. Trial-level correlation analysis was conducted to analyze the relationship between PFS hazard ratio (HR) and overall survival (OS) HR, Δ median PFS and Δ median OS. Correlation analysis at the neoadjuvant treatment arm level was performed between 1- to 5-year PFS and 5-year OS, median PFS and median OS. Subgroup analysis was performed in patients treated with standard neoadjuvant chemoradiotherapy (NCRT). The correlation was evaluated using the Pearson correlation coefficient r in weighted linear regression, with weight equal to patient size. In trial-level correlation, PFS were strongly associated with OS HR (r, 0.82 [95% confidence interval (CI), 0.42-0.97]) and Δ median survival (r, 0.83 [95% CI, 0.54-0.96]). In neoadjuvant treatment arms, there was a strong correlation between 1 to 5-year PFS rates and 5-year OS (r, 0.83-0.95), and median PFS and median OS (r, 0.97 [95% CI, 0.85-0.99]). NCRT subgroup analysis demonstrated acceptable consistency. In conclusion, we recommend PFS as an early efficacy endpoint in resected esophageal or GEJ cancer treated with neoadjuvant therapy.

4003 Background: In CheckMate 577 (NCT02743494), NIVO demonstrated a significant and clinically meaningful improvement in disease-free survival (DFS; primary endpoint) vs placebo (PBO) and was well tolerated in patients (pts) with resected (R0) stage II/III EC/GEJC who received neoadjuvant CRT and had residual pathologic disease. Median DFS doubled with NIVO vs PBO (22.4 vs 11.0 months; HR 0.69; 96.4% CI 0.56–0.86; P = 0.0003). Serious treatment-related adverse events (TRAEs) and TRAEs leading to discontinuation were reported for < 10% of pts with NIVO and 3% with PBO. Methods: Pts were randomized 2:1 to NIVO 240 mg or PBO Q2W for 16 weeks, followed by NIVO 480 mg or PBO Q4W. Here, we present additional efficacy, safety, and quality-of-life (QoL) data from CheckMate 577. Results: 794 pts were randomized (NIVO, 532; PBO, 262). Distant recurrence was reported for 29% vs 39% and locoregional recurrence for 12% vs 17% of pts in the NIVO vs PBO groups, respectively. Median distant metastasis-free survival was 28.3 vs 17.6 months with NIVO vs PBO (HR 0.74; 95% CI 0.60–0.92). Median progression-free survival 2 (PFS2; time from randomization to progression after subsequent systemic therapy, initiation of second subsequent systemic therapy, or death, whichever is earlier) was not reached with NIVO vs 32.1 months with PBO (HR 0.77; 95% CI 0.60–0.99). TRAEs with potential immunologic etiology (select TRAEs; sTRAEs) reported for NIVO are presented in the table. Results for the FACT-ECS and FACT-G7 showed similar trends for QoL improvement from baseline for NIVO and PBO during treatment and maintained benefit post-treatment. Conclusions: Adjuvant NIVO demonstrated clinically meaningful efficacy, an acceptable safety profile, and maintained QoL, providing further support for its use as a new standard of care for pts with resected EC/GEJC who received neoadjuvant CRT with residual pathologic disease. Clinical trial information: NCT02743494. [Table: see text]

Introduction: The article contains a summary of the issues of staging and therapy with an emphasis on the neoadjuvant treatment and associated tumor regression grade with the analysis of our own group of patients. Methods: Retrospective analysis of patients with rectal cancer who underwent a surgery at the 1st Department of Surgery – Thoratic, Abdominal and Injury Surgery; First Faculty of Medicine, Charles University in Prague and General University Hospital in Prague, Czech Republic, focusing on those who underwent neoadjuvant chemoradiotherapy and their pathologists evaluated tumor regression grade after the resection. Results: The group consists of 161 patients operated on between 2012 and 2016. 47 patients underwent neoadjuvant oncological treatment with further evaluation of the tumor regression grade by a pathologist, a scoring system according to Ryan was used. A complete pathological response was elicited in 10.4% of patients, no response in 35.4% of patients, and partial tumor regression in 54.2%. Conclusion: Although there is a difference in our results compared to foreign publications, the proportion of patients remains comparable. Studies evaluating the advantages versus disadvantages of neoadjuvant therapy will certainly follow, and the question of the suitability of surgical treatment as the only curative solution is partially raised.

Abstract Background. We report on the activity of the combination of epirubicin and docetaxel given in neoadjuvant setting for 4 and 8 cycles respectively in 2 successive series of patients with large operable or locally advanced, hormone receptor positive, HER-2 negative breast cancer. Patients and methods. Patients were treated from 2002 to 2006 with epirubicin 90 mg/m2 and docetaxel 75 mg/ m2 intravenously, every 3 weeks for 4 cycles before and 4 cycles after surgery (Series I - 13 patients), and from 2006 to 2010 with the same regimen administered for 8 cycles preoperatively (Series II - 37 patients), plus hormonal therapy for 5 years and radiation therapy if indicated. All Series I and 32 Series II patients were able to complete the preoperative chemotherapy. Results. A complete response was found in 1 patient from Series I and 13 patients from Series II and the partial remission in 10 patients from Series I and 21 patients from Series II. Two Series I and 3 Series II patients did not respond clinically. Response rate (Series I/Series II) was 84/92%. All 50 patients underwent surgery. In Series I patients, 3 pCR occurred in the breast and the axilla was histologically negative in 2 cases. No evidence of disease both in the breast and in the axilla was achieved in 7.6% (1/13) of patients. In Series II patients, 8 pCR occurred in the breast and axilla was histologically negative in 15 patients. No evidence of disease both in the breast and in the axilla occurred in 10.8% (4/37) of patients. G3-G4 toxicity included myelosuppression in 3 patients from Series I and all patients from Series II, and mucositis in 1 patient from Series I and 4 patients from series II. No other G3-4 toxicities or toxic deaths occurred. Five-year progression free survival was 38% and 90% in Series I and Series II patients respectively. Conclusions. The incidence of pathologic complete remissions was lower in our patient population, compared to reported data. A longer duration of the preoperative treatment might be associated with a longer progression-free survival.

Five electronic databases were searched for eligible records. Outcomes were presented and analyzed according to the objective response rate (ORR), progression-free survival (PFS) rate, and overall survival (OS) rate. Five records involving 2,024 participants were included in the study. The pooled analysis of OS and PFS were longer with ramucirumab (RAM) therapy than without RAM for OS (odds ratio OR = 0.90 , 95% confidence interval CI = 0.82 – 1.00 , p = 0.05 ) and PFS ( OR = 0.74 , 95 % CI = 0.57 – 0.96 , p = 0.02 ). Moreover, compared with the current first-line chemotherapy, the OS ( OR = 0.93 , 95 % CI = 0.83 – 1.04 , p = 0.19 ) and PFS ( OR = 0.82 , 95 % CI = 0.64 – 1.06 , p = 0.13 ) results were not significantly higher with RAM. The ORRs of the patients in the RAM therapy groups were significantly higher than those in the groups without RAM ( OR = 1.40 , 95 % CI = 1.14 – 1.73 , p = 0.001 ).

Background. Previous studies have shown the prognostic value of lactate dehydrogenase (LDH) in hepatocellular carcinoma (HCC), but the results are not persuasive. Therefore, the purpose of our study was to quantitatively explore the prognostic value of LDH in hepatocellular carcinoma.Methods. We searched the Web of Science, Embase, PubMed, and the Cochrane Library for literature published before October 2018 on the prognostic value of LDH in patients with hepatocellular carcinoma. The combined hazard ratios (HRs) and 95% confidence intervals (CIs) were utilized to assess the prognostic value of LDH in overall survival (OS), recurrence-free survival (RFS), and progression-free survival (PFS) of HCC. Subgroup analysis, sensitivity analysis, and metaregression were used to explore the source of heterogeneity. Funnel plots with Begg’s test and Egger’s test were used to detect potential publication biases. Furthermore, combined odds ratios (ORs) were utilized to assess the correlation between LDH and clinicopathological features.Results. A total of 10 nonrandomized controlled studies were included in this meta-analysis. The combined effects of LDH on HCC patients’ OS, RFS/DFS, and PFS were HR = 2.07, 95% CI: 1.63-2.62, P < 0.001; HR = 1.62, 95% CI: 1.37-1.90, P < 0.001; and HR = 1.96, 95% CI: 1.14-3.36, P = 0.014, respectively. Subgroup analysis and sensitivity analysis showed that the outcome was stable, and the results of the metaregression also identified statistical models as an important source of heterogeneity. Potential publication bias was detected in the OS studies, so the trim-and-fill method was used to explore publication bias, and the results showed stability. Furthermore, the combined OR suggests that LDH was significantly correlated with gender, Child-Pugh grade, alpha-fetoprotein, vascular invasion, and tumor size.Conclusions. Preoperative LDH elevation is significantly associated with poor prognosis in patients with HCC, which may be a promising factor in assessing the prognosis of patients with HCC.

Background: Osteosarcoma is the most frequent bone cancer occurring in children and adolescents aged 10–20 years. Several prognostic factors have been identified by studies done at western centers. The aim of our study was to identify the prognostic factors in Tunisian patients in order to improve their management. Methods: We reviewed the data of localized limb osteosarcoma patients treated in Salah Azaïz Institute from January 1980 to December 2018. Patient’s treatment and survival variables were assessed. Patients received a neoadjuvant chemotherapy and underwent surgery in an expert center. They received afterward an adjuvant chemotherapy depending on the tumor necrosis assessed by Huvos. Results: Eighty-five patients were enrolled. Mean duration of follow-up was 30 months (range 1–297 months). Males were 1.6 times more frequent, median age was 17 (from 1 to 62 years). Conventional osteoblastic osteosarcoma was the most frequent histological subtype (77%). Median tumor size was 10 cm. Femoral location was the most frequent (60%). The overall average history of symptoms was 103 days (4 to 423 days). The 5-year overall-survival was 38% and the event free survival 32%. Tumor site, lactate dehydrogenase levels, high methotrexate levels at 24 h, clinical evaluation of the tumor perimeter, surgery type and delay of relapse were found to affect overall survival. Tumor site, Lactate dehydrogenase levels and clinical evaluation of the tumor perimeter affected the progression free survival. Conclusion: Demographic characteristics of Tunisian patients are mainly the same than worldwide. Femoral site, normal level of lactate dehydrogenase, a clinical response during neoadjuvant treatment, an R0 surgery, a delay of relapse over 2 years and Median H24 Methotrexate level superior to 4.4 µmol/l were associated with a better prognosis in our study.

Purpose: To improve resectability in patients with stage III–IVA thymic epithelial neoplasms, neoadjuvant chemotherapy and radiotherapy are considered. This retrospective study aimed to investigate the efficacy and safety of neoadjuvant therapies using modern techniques in thymic epithelial neoplasms. Methods: We included 32 patients with Masaoka stage III–IV disease treated at our institution from January 2010 to December 2017. Data regarding clinicopathologic characteristics, treatment protocols, toxicities, and survival were collected. Response was evaluated according to the Response Evaluation Criteria in Solid Tumours 1.1. Survival was assessed using the Kaplan-Meier method. Adverse events were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. Results: Neoadjuvant radiotherapy alone, chemotherapy alone, sequence chemoradiotherapy, and concurrent chemoradiotherapy were administered to 10 (31.3%), 9 (28.1%), 3 (9.4%), and 10 (31.3%) patients, respectively. Twenty-nine patients (90.6%) underwent R0 resection. The median follow-up time was 38.0 months (3.3–109.5 months). After neoadjuvant therapy, 18 patients (56.3%) achieved partial response and 14 (43.8%) had stable disease. Pathologic complete response was achieved in 6 patients (18.8%), all of whom had thymic carcinoma. The 5-year overall and progression-free survival rates were 90.9% and 67.5%, respectively. For patients with thymic carcinoma, the 5-year overall and progression-free survival rates were 80.0% and 66.2%, respectively. Grade 3 toxicities were observed in only 1 patient (leukopenia). Conclusions: For patients with primary unresectable thymic neoplasms, neoadjuvant chemoradiotherapy is an efficient and safe choice, with favorable response and survival and moderate toxicities. Patients with thymic carcinoma might benefit more from neoadjuvant therapies.

Abstract Background Despite obvious advances over the last decades, locally advanced adenocarcinomas of the gastroesophageal junction (GEJ) still carry a dismal prognosis with overall 5-year survival rates of less than 50% even when using modern optimized treatment protocols such as perioperative chemotherapy based on the FLOT regimen or radiochemotherapy. Therefore the question remains whether neoadjuvant chemotherapy or neoadjuvant radiochemotherapy is eliciting the best results in patients with GEJ cancer. Hence, an adequately powered multicentre trial comparing both therapeutic strategies is clearly warranted. Methods The RACE trial is a an investigator initiated multicenter, prospective, randomized, stratified phase III clinical trial and seeks to investigate the role of preoperative induction chemotherapy (2 cycles of FLOT: 5-FU, leucovorin, oxaliplatin, docetaxel) with subsequent preoperative radiochemotherapy (oxaliplatin weekly, 5-FU plus concurrent fractioned radiotherapy to a dose of 45 Gy) compared to preoperative chemotherapy alone (4 cycles of FLOT), both followed by resection and postoperative completion of chemotherapy (4 cycles of FLOT), in the treatment of locally advanced, potentially resectable adenocarcinoma of the gastroesophageal junction. Patients with cT3–4, any N, M0 or cT2 N+, M0 adenocarcinoma of the GEJ are eligible for inclusion. The RACE trial aims to enrol 340 patients to be allocated to both treatment arms in a 1:1 ratio stratified by tumour site. The primary endpoint of the trial is progression-free survival assessed with follow-up of maximum 60 months. Secondary endpoints include overall survival, R0 resection rate, number of harvested lymph nodes, site of tumour relapse, perioperative morbidity and mortality, safety and toxicity and quality of life. Discussion The RACE trial compares induction chemotherapy with FLOT followed by preoperative oxaliplatin and 5-Fluorouracil-based chemoradiation versus preoperative chemotherapy with FLOT alone, both followed by surgery and postoperative completion of FLOT chemotherapy in the treatment of locally advanced, non-metastatic adenocarcinoma of the GEJ. The trial aims to show superiority of the combined chemotherapy/radiochemotherapy treatment, assessed by progression-free survival, over perioperative chemotherapy alone.
