Abstract
IMPORTANCE Standard first-line regimens for patients with metastatic gastroesophageal adenocarcinomas have an approximate 40% objective response rate (ORR). The combination of leucovorin, fluorouracil, irinotecan, and oxaliplatin (FOLFIRINOX) has been efficacious as first-line therapy for other gastrointestinal cancers, such as pancreatic and colon cancers. OBJECTIVE To evaluate the clinical activity and safety of FOLFIRINOX as first-line treatment for patients with advanced gastroesophageal adenocarcinoma. DESIGN, SETTING, AND PARTICIPANTS This is an open-label, single-arm phase 2 study of first-line FOLFIRINOX in patients with advanced gastroesophageal adenocarcinoma. Estimated sample size included 41 patients with ERBB2-negative disease with 90% power to detect an ORR of 60% or greater with α of .10. No enrollment goal was planned for ERBB2-positive patients, but they were allowed to receive trastuzumab in combination with FOLFIRINOX. INTERVENTIONS Starting doses were fluorouracil, 400 mg/m2 bolus, followed by 2400 mg/m2 over 46 hours; leucovorin, 400 mg/m2; irinotecan, 180 mg/m2; and oxaliplatin, 85 mg/m2. Trastuzumab was administered as a 6 mg/kg loading dose, followed by 4 mg/kg every 14 days in patients with ERBB2-positive disease. MAIN OUTCOMES AND MEASURES The primary end point was ORR by the Response Evaluation Criteria in Solid Tumors, version 1.1. Secondary end points included safety profile, progression-free survival (PFS), overall survival (OS), and duration of response. RESULTS From November 2013 to May 2018, 67 patients were enrolled (median [range] age, 59.0 [34-78] years; including 56 [84%] men), and 26 of 67 (39%) had ERBB2-positive disease. Median follow-up was 17.4 months. The ORR was 61%(95% CI, 44.5%-75.8%) (25 of 41) in the ERBB2-negative group and 85% (95% CI, 65.1%-95.6%) (22 of 26) in the ERBB2-positive group, including 1 patient with complete response. For ERBB2-negative patients, median PFS was 8.4 months and median OS was 15.5 months; for ERBB2-positive patients, median PFS was 13.8 months and median OS was 19.6 months. Fifty-six patients (84%) had dose modifications or treatment delays. The most common toxic effects were neutropenia (91%, n = 61), diarrhea (63%, n = 42), peripheral sensory neuropathy (61%, n = 41), and nausea (48%, n = 32), with no unexpected toxic effects. CONCLUSIONS AND RELEVANCE The FOLFIRINOX regimen with or without trastuzumab was associated with improved ORR and PFS in patients with advanced gastroesophageal adenocarcinoma in the first-line setting. This regimen may be a reasonable therapeutic option for patients with preserved performance status. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01928290.

Garcia, JR, Cozar, M, Soler, M, Bassa, P, Riera, E, Buxeda, M, Valls, E, Ferrer, J
Revista espanola de medicina nuclear e imagen molecular. 2020;(4):204-211
Abstract
AIM: To standardize acquisition protocols for 18F-Choline PET/CT to prevent from urine interference, to determine the best time point for the whole-body study, and to assess whether "dual point" acquisition allows for differentiating malignant vs. benign lesions. METHODS One hundred consecutive patients with prostate cancer were prospectively studied. Immediately after 18F-Choline injection, a pelvis study was acquired, and a whole-body was subsequently obtained 1 and 2 hours p.i. Mean SUVmax was obtained in regions and for every sequential imaging. Mean analysis (χ2) and SUV percentage change (2/1 hours; 1 hours/0 min) were obtained. Metabolic pattern dynamics were assessed: accumulative vs. clearance. Patient follow-up after therapy and directed classification whenever ethically possible were performed. RESULTS Fifty-three prostate foci, without disturbing urinary activity was ever found on early images. Accumulative pattern in 42, with percentage increase was: 0 min/1 hour: +16.7% (χ20.94); 1/2 hours: +10,0% (χ2 0.83). Clearance pattern in 11, with percentage decrease: 0 min/1 hour: -21.4% (χ20.91): -7.7% (χ20.85), corresponding in 7 to initial staging and in 4 post-radiotherapy biochemical recurrence. Every infradiaphragmatic uptake (n: 24) showed accumulative pattern, with percentage increase of +9.1% (χ20.97), all of them depicted on early imaging. As for 12 supradiaphragmantic uptake, 8 of them showed clearance pattern with percentage decrease: -13.0% (χ20.95). Accumulative pattern showed in 4 of them with percentage increase +13.0% (χ2 0.96), thus being assessed as invasive/malignant. Every bone uptake (n: 18) showed accumulative pattern, with percentage increase: +17.1% (χ20.95), all of them depicted on 1 hour imaging. CONCLUSIONS As for prostate assessment is concerned, dual point at 0 min/1 hour proved to be the best procedure. As for supradiaphragmatic lymph-nodes detection, dual point with 1/2 hours performed best. As for infradiaphragmatic and bone involvement, as well as for inconclusive findings, the 2 hour imaging increased our diagnostic confidence.

Abstract
The global, randomized NAPOLI-1 phase 3 trial reported a survival benefit with liposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (nal-IRI+5-FU/LV) in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) after previous gemcitabine-based therapy. Median overall survival (OS) with nal-IRI+5-FU/LV was 6.1 vs 4.2 months with 5-FU/LV alone (unstratified hazard ratio [HR] = 0.67, P = .012). Herein, we report efficacy and safety results from a post-hoc subgroup analysis of Asian patients treated at Asian centers. Primary study endpoint was OS; secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and safety. Patients receiving nal-IRI+5-FU/LV (n = 34) had significantly longer median OS versus 5-FU/LV (n = 35) (8.9 vs 3.7 months; unstratified HR = 0.51, P = .025). Patients had significantly increased median PFS with nal-IRI+5-FU/LV versus 5-FU/LV (4.0 vs 1.4; unstratified HR = 0.48, P = .011), and increased ORR (8.8% vs 0; P = .114). nal-IRI monotherapy (n = 50) numerically improved efficacy endpoints versus 5-FU/LV (n = 48): median OS was 5.8 versus 4.3 months (HR = 0.83, P = .423) and median PFS was 2.8 versus 1.4 months (HR = 0.69, P = .155). Grade ≥3 neutropenia was reported more frequently with nal-IRI+5-FU/LV versus 5-FU/LV (54.5% vs 3.4%), and incidence of grade ≥3 diarrhea was comparable between the two arms (3.0% vs 6.9%). This subgroup analysis confirms nal-IRI+5-FU/LV as an efficacious treatment option that improves survival in Asian patients with mPDAC that progressed after gemcitabine-based therapy, with a safety profile agreeing with previous findings. The nal-IRI+5-FU/LV regimen should represent a new standard of care for these patients in Asia. (Clinicaltrials.gov: NCT01494506).

Abstract
BACKGROUND S-1 plus leucovorin and oxaliplatin showed promising efficacy for treatment of advanced gastric cancer in a randomised phase 2 study. We aimed to evaluate the efficacy and safety of oral TAS-118 (S-1 plus leucovorin) and oxaliplatin versus S-1 plus cisplatin in patients with advanced gastric cancer. METHODS We did a randomised, open-label, phase 3 trial in 62 centres across Japan and South Korea. Patients aged 20 years or older, with a histologically confirmed advanced gastric cancer with negative or unknown HER2 status, with Eastern Cooperative Oncology Group performance status of 0 or 1, measurable or evaluable metastatic lesions, and no previous treatment were randomly assigned (1:1) via an interactive web response system using the minimisation method, stratified by performance status, presence of a measurable lesion, and country, to receive TAS-118 (S-1 40-60 mg and leucovorin 25 mg orally twice daily for 7 days) plus oxaliplatin (85 mg/m2 intravenously on day 1) every 2 weeks, or S-1 (40-60 mg orally twice daily) for 21 days plus cisplatin (60 mg/m2 intravenously on day 1 or 8) every 5 weeks. The primary endpoint was overall survival in patients who had advanced gastric cancer with measurable or evaluable metastatic lesions and who received the study drug. Safety was assessed in all patients who received the study drug. This study was registered at ClinicalTrials.gov, NCT02322593. FINDINGS Between Jan 28, 2015, and Dec 5, 2016, 711 patients were randomised to TAS-118 plus oxaliplatin (n=356) or S-1 plus cisplatin (n=355). 11 untreated patients and 19 ineligible patients were excluded from the primary analysis (TAS-118 plus oxaliplatin group n=347, S-1 plus cisplatin group n=334) following recommendation from the independent data monitoring committee. After median follow-up of 26·0 months (IQR 22·0-32·8), median overall survival was 16·0 months (95% CI 13·8-18·3) in the TAS-118 plus oxaliplatin group and 15·1 months (95% CI 13·6-16·4) in the S-1 plus cisplatin group (hazard ratio 0·83, 95% CI 0·69-0·99; p=0·039). The most common grade 3 or higher adverse events in the 352 patients in the TAS-118 plus oxaliplatin group and the 348 patients in the S-1 plus cisplatin group were anaemia (56 [16%] vs 64 [18%]), neutropenia (54 [15%] vs 88 [25%]), decreased appetite (53 [15%] vs 46 [13%]), diarrhoea (33 [9%] vs 15 [4%]), and peripheral sensory neuropathy (30 [9%] vs one [<1%]). Serious adverse events were observed in 155 (44%) of 352 patients in the TAS-118 plus oxaliplatin group and 159 (46%) of 348 patients in the S-1 plus cisplatin group. Two treatment-related deaths occurred in the TAS-118 plus oxaliplatin group (pulmonary tuberculosis and viral pneumonia). INTERPRETATION TAS-118 plus oxaliplatin showed a clinically meaningful improvement in efficacy compared with S-1 plus cisplatin, and could be considered a new first-line treatment option for advanced gastric cancer in Asian patients.

Jeong, WJ, Choi, BJ, Lee, SC
Asian journal of surgery. 2019;(2):450-457
Abstract
AIM: To report our institution's experiences with pure transanal total mesorectal excision (TME) of rectal cancer using single-port equipment and to discuss the feasibility and safety of the technique. METHODS Between February and December 2017, 12 patients who were selected underwent NOTES TME in our institution. The preoperative assessment included blood analyses with carcinoembryonic antigen serum concentration, full colonoscopy, pelvic magnetic resonance imaging (MRI), and computed tomography (CT) of the abdomen and chest. RESULTS Ten patients (male:female, 6:4) treated with transanal TME with colorectal anastomosis in our institution were reviewed. Pure TME was performed without laparoscopic assistance in 6 of 10 patients. The mean operative time was 303.5 min. The median distal margin was 2.1 (0.2-4.2) cm. The median number of harvested lymph nodes is 17.5. Except one patient with anastomotic leak, most patients started dietary intake on postoperative day (POD) 3 and were discharged on POD 7. Anastomotic leak was the only postoperative complication. CONCLUSION This study showed that pure natural orifice transluminal endoscopic surgery (NOTES) TME with coloanal anastomosis for rectal cancer is safe and feasible in selected cases.

Abstract
IMPORTANCE Ramucirumab, a human IgG 1 antibody against vascular endothelial growth factor receptor 2, has been shown to improve progression-free survival and overall survival in patients with advanced gastric cancer in the second-line setting. OBJECTIVE To compare progression-free survival for S-1 and oxaliplatin plus ramucirumab with that for S-1 and oxaliplatin plus placebo in patients with advanced gastric cancer. DESIGN, SETTING, AND PARTICIPANTS This phase 2, double-blind randomized clinical trial (RAINSTORM [First-line S-1 Plus Oxaliplatin With or Without Ramucirumab Followed by Paclitaxel Plus Ramucirumab in Patients With Advanced Gastric Cancer]) was conducted from October 12, 2015, to April 11, 2018, at 36 sites in Japan, South Korea, and Taiwan. Participants were chemotherapy-naive patients (n = 189) with metastatic gastric or gastroesophageal adenocarcinoma. Analyses of the full analysis set and safety population were conducted between November 27, 2017, and June 4, 2018. INTERVENTIONS Patients randomized to the ramucirumab plus S-1 and oxaliplatin arm received S-1, 80 to 120 mg/d twice daily, on days 1 to 14 and oxaliplatin, 100 mg/m2, on day 1 with ramucirumab, 8 mg/kg, on days 1 and 8 in part A (21-day cycle). Patients randomized to the placebo plus S-1 and oxaliplatin arm received the same S-1 and oxaliplatin dosage as well as placebo on days 1 and 8 in part A. Eligible patients received second-line paclitaxel, 80 mg/m2, on days 1, 8, and 15 and ramucirumab, 8 mg/kg, on days 1 and 15 in part B (28-day cycle). MAIN OUTCOMES AND MEASURES The primary end point was progression-free survival, analyzed using the stratified log-rank test; the hazard ratio (HR) was estimated using the stratified Cox proportional hazards regression model. Secondary end points included overall survival and adverse events. RESULTS In total, 189 patients were randomized and received treatment: 96 to the ramucirumab plus S-1 and oxaliplatin arm and 93 to the placebo plus S-1 and oxaliplatin arm. Among the 189 patients, 121 (64.0%) were male, and the median (range) age was 62.0 (26-84) years. Median progression-free survival was not prolonged in the ramucirumab plus S-1 and oxaliplatin arm compared with the placebo plus S-1 and oxaliplatin arm (6.34 [80% CI, 5.65-6.93] vs 6.74 [80% CI, 5.75-7.13] months; HR, 1.07; 80% CI, 0.86-1.33; P = .70). Median overall survival was 14.65 (80% CI, 12.39-15.67) months in the ramucirumab plus S-1 and oxaliplatin arm and 14.26 (80% CI, 13.83-17.31) months in the placebo plus S-1 and oxaliplatin arm (HR, 1.11; 80% CI, 0.89-1.40; P = .55). The most commonly reported grade 3 or higher treatment-emergent adverse events in the ramucirumab plus S-1 and oxaliplatin arm in part A were decreased neutrophil count (14 patients [14.6%]), hypertension (10 patients [10.4%]), and anemia (10 patients [10.4%]). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, the addition of ramucirumab to first-line S-1 and oxaliplatin treatment did not prolong progression-free survival or overall survival compared with S-1 and oxaliplatin alone among East Asian patients with advanced gastric cancer; no new safety signals for ramucirumab were identified.

Abstract
PURPOSE The aim of this study was to assess the safety of rectal surgery after 5-fluorouracil-leucovorin-oxaliplatin chemotherapy (FOLFOX6). METHODS This was a prospective, multicenter study in 11 Japanese hospitals. We included patients with rectal cancer who received 4 courses of modified FOLFOX6 (mFOLFOX6) before rectal surgery and examined the postoperative complication rate, the clinicopathological response, and the rate of chemotherapy-related adverse events (UMIN 000012559). RESULTS The study population included 36 men and 5 women. The average age of the patients was 60.8 years and the average body mass index was 23.1 kg/m2. After 4 courses of chemotherapy, grade 2 peripheral nerve disorder and other grade 3 adverse events were seen in 3 patients each (7.3%). Twenty-eight (73.7%) and 8 (21.1%) patients underwent low anterior resection and abdominoperineal resection, respectively. The pelvic nerves were preserved in 35 patients. Surgical morbidity (grade ≥ 3) occurred in 4 patients (10.5%). Anastomotic leakage occurred after surgery in 2 patients (7.1%). No patients achieved pathologically complete remission. However, downstaging of the clinical stage and N stage was seen in 17 (41.5%) and 22 (53.7%) patients, respectively. CONCLUSIONS Surgery after four courses of mFOLFOX6 chemotherapy can be a safe and promising strategy for patients with locally advanced rectal cancer.

Abstract
BACKGROUND Little information from prospective clinical trials is available on the influences of surgical approaches on postoperative body compositions and nutritional status. We designed a prospective non-randomized trial to compare postoperative chronological changes in body composition and nutritional status between laparoscopic and open distal gastrectomy for stage I gastric cancer (GC). METHODS Body compositions and nutritional indicators in blood tests were measured at the baseline and at the 1st, 3rd, 6th, and 12th postoperative months (POM). The primary end point was the decrease relative to the baseline in the body muscle mass at POM 6. RESULTS Ninety-six patients for the laparoscopic group and 52 for the open group were eligible for data analysis. No significant differences were found in any baseline demographics, body compositions, and nutritional indicators between the groups. The changes of body muscle mass at POM 6 were similar in both groups. Overall, no significant differences between the groups were observed in any of the body composition and nutritional indicators during the first year after surgery. CONCLUSIONS Postoperative body compositions and nutritional status were not affected by surgical approaches during the first 12 months after surgery in patients who underwent distal gastrectomy for stage I GC.

Abstract
BACKGROUND Gastrectomy for gastric cancer is a significant cause of secondary exocrine pancreatic insufficiency. Pancreatic enzyme replacement therapy may influence nutritional status and quality of life after gastrectomy, but the pertinent clinical research to date remains controversial. A randomized controlled trial to test this hypothesis was carried out. METHODS After gastrectomy, 43 patients with gastric cancer were randomly assigned to a normal diet (Normal-d; n = 21) or to a pancreatic enzyme supplementation diet (PES-d; n = 22) and were followed up during a 12-month period, assessing nutritional status and quality of life through body mass index (BMI), instant nutritional assessment (INA) class status, serum pre-albumin (SPA) values, and GastroiIntestinal Quality of Life Index (GIQLI). RESULTS BMI was not significantly influenced by the type of diet; INA class status was significantly improved in the PES-d arm, particularly during the first 3 months after gastrectomy; SPA levels increased in both arms at 6 months after gastrectomy, reaching significantly higher values in the PES-d arm at 12 months. GIQLI was not significantly influenced by the type of diet throughout the follow-up period; however, this index significantly improved in the PES-d arm between the first and third month after gastrectomy. CONCLUSIONS PES-d improves nutritional status and quality of life after gastrectomy for gastric cancer, particularly within 3 months from the operation. A larger, multicenter trial is necessary to address the potential influence of several confounding variables such as disease stage and adjuvant treatments.

Abstract
OBJECTIVES Aflibercept (ziv-aflibercept) significantly improves progression-free (PFS) and overall survival (OS) when added to 5-fluorouracil, leucovorin and irinotecan (FOLFIRI), compared with FOLFIRI alone, in patients with metastatic colorectal cancer previously treated with oxaliplatin-based therapy. This subset analysis of the VELOUR study investigates aflibercept plus FOLFIRI versus placebo plus FOLFIRI according to age. METHODS Efficacy and safety were analyzed by treatment arm and age (≥ or <65years). RESULTS Overall, 443 patients were ≥65years old (205 in aflibercept arm; 238 in placebo arm) and 783 were <65years old (407 in aflibercept arm; 376 in placebo arm). Median OS was 12.6 versus 11.3months (hazard ratio [HR]: 0.85; 95.34% CI 0.68-1.07) in patients ≥65years old and 14.5 versus 12.5months (HR: 0.80; 95.34% CI 0.67-0.95) in those patients <65years old, for patients receiving FOLFIRI plus aflibercept or placebo, respectively. There was no interaction between treatment and age. Treatment-emergent adverse events (AEs) were comparable for patients <65years and ≥65years old. The incidence of grade 3/4 AEs was higher for patients ≥65years old than for those <65years old in both the aflibercept (89.3% versus 80.5%) and placebo (67.4% versus 59.4%) arms. Interaction tests for grade 3/4 antiangiogenic agent-related AEs suggested no heterogeneity between the older and younger patient populations (p>0.1). CONCLUSION A limited but consistent benefit on both OS and PFS was associated with the addition of aflibercept to FOLFIRI compared with placebo in patients <65 and ≥65years old, with a marked but manageable increase in the toxicity profile in older patients.
