Abstract
INTRODUCTION In patients with advanced gastric cancer refractory to chemotherapy, the treatment options are limited. Via this phase II study, we aimed to assess the efficacy and safety of oxaliplatin in combination with 5-fluorouracil and l-leucovorin (modified FOLFOX6). METHODS Patients who had histologically confirmed metastatic gastric cancer refractory to ≥ two previous chemotherapy regimens were included. The primary endpoint was the overall response rate (ORR) by an independent central review. According to an assumption of a threshold ORR of 10% and expected ORR of 25%, with α = 0.05 and β = 0.20, at least 33 patients were required. The secondary endpoints included overall survival (OS), progression-free survival (PFS), quality of life measured by EQ-5D, and safety. RESULTS Among the 35 enrolled patients, 33 were included in the primary analysis. All patients previously received fluoropyrimidines, cisplatin, and taxanes, and 24 (73%) were pretreated with irinotecan. The confirmed ORR was 27% [95% confidence interval (CI) 13-46]. The median PFS and OS were 2.2 (95% CI 1.2-3.2) and 5.6 (95% CI 4.1-7.0) months, respectively. In the multivariate analyses, immunotherapy within 90 days and a Glasgow Prognostic Score of 0 were associated with better treatment outcomes. The most common grade ≥ 3 adverse event was neutropenia (36%), and no febrile neutropenia was observed. The median EQ-5D scores did not change from baseline at 2, 4, and 8 weeks (p value = 0.38, 0.79, and 0.98, respectively). CONCLUSION Modified FOLFOX6 (mFOLFOX6) showed substantial activity and acceptable toxicity for chemotherapy-refractory advanced gastric cancer.

Abstract
OBJECTIVE The purpose of this study was to compare the efficacy of 5-fluorouracil (5-FU) with that of other treatments of actinic keratosis (AK). METHODS A systematic literature review of five databases (including Medline and EMBASE) was first performed to identify randomized controlled trials (RCTs). A network meta-analysis (NMA) based on a random-effects Bayesian model was then performed on the outcomes for patients with total clearance and lesions reduced from baseline. Five treatments (viz., 0.5% 5-FU with 10% salicylic acid [5-FU/SA], 5% 5-FU cream, 3% diclofenac sodium, cryosurgery, and vehicle) were evaluated. RESULTS A total of 11 studies involving 2,256 patients with AK were included in this NMA. The overall risk of bias among the included studies was low. All treatments were significantly better than the vehicle both for patients with total clearance and for lesions reduced from baseline. Among patients with total clearance, 5% 5-FU cream (56.8%) and 5-FU/SA (35.7%) were likely to be more effective than the other treatments, whereas 5% 5-FU cream (98.6%) was likely the most effective in the group of lesions reduced from baseline. CONCLUSION 5-FU, diclofenac sodium, and cryosurgery are all useful for AK treatment, with 5-FU being the most effective.

Abstract
BACKGROUND To compare the efficiency and safety of uterine artery embolization (UAE) combined with local infusion of methotrexate (MTX) or MTX and 5-fluorouracil (5-FU) in the treatment of ectopic pregnancy (EP). METHODS One hundred women with EP were prospectively enrolled from December 2012 to February 2015 and randomly allocated into 2 groups. One group was treated with UAE combined MTX, and the other with UAE combined with MTX and 5-FU. Local MTX was administrated at a dose of 80 to 120 mg, based on the initial β-human chorionic gonadotropin (β-HCG) levels, and 5-FU was given intra-arterially at a uniform dose of 0.5 g. RESULTS Bilateral UAE was successfully performed in all 100 patients, 88 of whom were clinically successfully treated, 45 (91.8%) in the MTX group, and 43 (87.8%) in the MTX + 5-FU group; 89% of the patients achieved normalization of β-HCG below 70,000 mIU/mL within 14 to 21 days postoperatively. The time to successful β-HCG resolution was 26.74 ± 5.57 days for patients receiving MTX + UAE treatment, and 27.57 ± 5.08 days for those treated with additional 5-FU. Six patients had subsequent intramuscular injections of MTX and 6 had a unilateral salpingectomy after the treatment failure. Mild immediate side effects accounted for 24.5% in the sole MTX and 58.3% in MTX + 5-FU group. CONCLUSION A combination of UAE and intrauterine infusion of MTX showed comparable efficiency to UAE combined with a local infusion of MTX and 5-FU in treating EP patients with the intention to preserve fertility.

Clinical colorectal cancer. 2018;(3):187-197
Abstract
BACKGROUND We performed a meta-analysis of previous reports evaluating the effect of mFIO (modified FOLFIRINOX; leucovorin, 5-fluorouracil, irinotecan, oxaliplatin) regimens in advanced pancreatic cancer. MATERIALS AND METHODS We performed a meta-analysis of reported studies in PubMed, Scopus, and Web of Science (1950-2016) in December 2016. The inclusion criteria were randomized trials, prospective or retrospective cohorts, patients with metastatic pancreatic adenocarcinoma, the use of mFIO or FOLFIRINOX (FIO) chemotherapy, and available information for ≥ 1 efficacy endpoint (response rate, progression-free survival, and/or overall survival). The outcomes were compared according to the chemotherapy regimen using a random effects model. We also performed a meta-regression analysis to evaluate the effect of dose reductions on outcomes. RESULTS Of 2525 abstracts, 32 were considered eligible. Modifications in the FIO regimen included omission of the 5-fluorouracil bolus and/or dose reductions in infusional 5-fluorouracil, irinotecan, and/or oxaliplatin. mFIO was not associated with inferior response rates (32% vs. 33%; P = .879), lower rates of survival at 11 months (47% vs. 50%; P = .38), or lower 6-month progression-free survival rates (47% vs. 53%; P = .38). The meta-regression of the percentage of dose reduction failed to show any association. CONCLUSION The results of the present meta-analysis with a combined sample size of 1461 patients suggest that it is reasonable to consider mFIO regimens for patients with metastatic pancreatic adenocarcinoma.

Abstract
BACKGROUND/AIM: Few clinical trials are available for advanced biliary tract carcinoma (BTC). We conducted this randomized phase II clinical trial to explore efficacy and safety of 5-fluorouracil/leucovorin (5-FU/LV - de Gramont) or the same regimen plus oxaliplatin (Folfox 4) as first-line treatment of advanced BTC. PATIENTS AND METHODS Primary endpoint was overall survival (OS); secondary endpoints were progression-free survival (PFS), response and toxicity. RESULTS A total of 48 patients were enrolled, 23 in de Gramont arm and 25 in the Folfox arm. Disease control rate was 56.5% for de Gramont vs. 72% for Folfox. RR was 21.7% for de Gramont arm and 28% for Folfox arm (p=0.12). PFS was in favor of Folfox (5.2 vs. 2.8 months; p=0.031). OS was 7.5 and 13.0 months for de Gramont and Folfox arm respectively (p=0.0010). Toxicity was generally mild in both arms. CONCLUSION Folfox 4 could be considered a valid option as first-line treatment of BTC due to its efficacy and tolerability.

Abstract
BACKGROUND Prospective data on chemotherapy for (frail) elderly patients with advanced colorectal cancer (aCRC) are scant. UFT/leucovorin might be as effective as and less toxic than capecitabine. We firstly randomized both agents in patients >65 years with aCRC not amenable to receive combination chemotherapy. PATIENTS AND METHODS Patients were randomised between first-line oral UFT/leucovorin and capecitabine in a Dutch multicentre trial. Primarily, efficacy and toxicity were determined. Secondary, quality of life (QoL) and abbreviated common geriatric assessment (aCGA) were analysed. RESULTS Sixty-seven patients were randomised with a median age of 77 years and 96% being frail. After interim analysis it was decided to stop recruitment because of low accrual. At a median follow up of 34 months, the median progression-free survival (PFS) and overall survival (OS) were similar for both therapies, being 21 weeks (p=0.17) and 12 months (p=0.83), respectively. The overall response rates were 24% and 21%, respectively. Two patients died of possible treatment related complications in the UFT/leucovorin arm and 3 patients in the capecitabine arm. For UFT/leucovorin significantly less grade 3 or 4 hand/foot syndrome (0 vs 5) was observed. Overall, PFS was related to Charlson-comorbidity index (p=0.049), LDH (p=0.0011) and albumin (p=0.009). OS was related to LDH (p=0.0003), albumin (p=0.0001), QoLC30/CR38 (p=0.041), QoL visual analogue scale (VAS; p=0.016), and GFI (p=0.028). CONCLUSION UFT/leucovorin and capecitabine had similar efficacy and different toxicity profiles in frail elderly patients with aCRC. Baseline serum levels of albumin and LDH, Charlson-comorbidity index, GFI and QoL were prognostic for clinical outcome.

Abstract
BACKGROUND The purpose was to evaluate prevention of oral mucositis (OM) using chlorhexidine compared with placebo and with oral cooling (cryotherapy) during fluorouracil (5-FU)-based chemotherapy in gastrointestinal (GI) cancer. METHODS Patients with previously untreated GI cancer receiving bolus 5-FU/leucovorin chemotherapy were randomized to chlorhexidine mouthrinse 3 times a day for 3 weeks (Arm A), double-blind placebo (normal saline) with the same dose and frequency (Arm B), or cryotherapy with crushed ice 45 minutes during chemotherapy (Arm C). Patients self-reported on severity (CTC-grading) and duration of OM. RESULTS Among 225 patients randomized, 206 answered the questionnaire (70, 64, and 63 patients in Arms A, B, and C, respectively) and were well balanced with respect to diagnoses, stage, age, sex, smoking habits, and performance status. Mucositis grade 3-4 occurred more frequently in Arm B (33%) than in A (13%, P< .01) and C (11%, P< .005). Duration was significantly longer in B than in both A (P= .035) and C (P= .003). CONCLUSIONS The frequency and duration of OM are significantly improved by prophylactic chlorhexidine and by cryotherapy. The latter is easy and inexpensive but has limited use, as it is drug- and schedule-dependent. The current study is the first double-blind randomized evaluation of prophylactic chlorhexidine in a large adult patient population with solid tumors receiving highly OM-inducing chemotherapy. A role for chlorhexidine in the prevention of OM is suggested, which should be evaluated further.

Abstract
AIM: Adjuvant chemotherapy is recommended for stage III colon cancer. The aim of this study was to identify important prognostic factors among patients with colon cancer receiving adjuvant 5-FU-based treatment. METHODS Data sets of 855 colon cancer patients treated between 1992 and 1999 within a multicenter adjuvant trial comparing 5-FU modulation with folinic acid or interfereron-alpha were examined. Backward elimination in a proportional hazards model was used to identify prognostically relevant clinical and pathological factors. RESULTS Tumor recurrence (p<0.001), duration of adjuvant treatment (p<0.001), tumor substage (p=0.004), age (p=0.005), grading (p=0.016), treatment-related toxicity (p=0.021), and treatment (p=0.031) were identified in descending order of importance as prognostic factors for overall survival. CONCLUSIONS Adjuvant 5-FU-based treatment should be performed for at least 6months with a stepwise adjustment of 5-FU doses until toxicity >WHO II. Substages should be reported separately and used for stratification in future trials due to their broad variation in outcome. In the future, this may result in adjuvant treatment of stage III colon cancer adjusted for the risk of substages.

Japanese journal of clinical oncology. 2007;(6):469-72
Abstract
A randomized phase II clinical trial is being conducted for patients with advanced or recurrent gastric cancer, in order to select the most promising treatment for subsequent evaluation in a large-scale phase III trial. We compare four chemotherapeutic treatments, which include two sequential and two combination regimens using paclitaxel with 5-fluorouracil or S-1, an oral fluorouracil derivative. The primary endpoint is 10-month overall survival rate, while the secondary endpoints are adverse events, time to treatment failure and progression-free survival. A Bayesian method is used to provide a statistical rule for monitoring the trial. Forty patients per treatment regimen (160 in total) were randomized into one of the four regimens using a centralized dynamic method.

Abstract
Hepatic arterial infusion (HAI) chemotherapy is accepted to be an option in patients with non-resectable metastases from colorectal cancer confined to the liver. In a multi-istitutional trial, 76 patients were randomly assigned to receive HAI versus HAI plus systemic bolus 5-fluorouracil and leucovorin. The primary endpoint was survival, followed by response, recurrence and toxicity. Survival was longer for HAI plus systemic chemotherapy (HAI+SYC) than HAI (median, 20 vs. 14 months; p = 0.0033), as were responses (47.5% and 41.7%; p = 0.09) and time to hepatic progression (12 vs. 8 months; p = 0.039). Side effects included haematological toxicity that was mostly mild and reversible in 432 cases. Neutropenia grade 3 occurred in four patients in the HAI+SYC arm and one in the HAI arm. Diarrhoea occurred in 20% and 7% of patients and stomatitis occurred in 18% and 2%, respectively. On the contrary biliary toxicity was significant; twelve patients had evidence of bilirubin elevations of more than 3 mg/dl (six in each arm), and two had asymptomatic arterial biliary-tree fistulae: one in the HAI+SYC arm and one in the HAI arm. Grade 3 elevation in alkaline phosphatase and aminotransferase levels occurred in 26% and 24%, respectively. In conclusion, the combination of HAI+SYC is active and safe showing a clinical advantage with respect to simple HAI, increasing overall survival, response rate and time to progression.
