Everolimus after hepatic arterial embolisation therapy of metastases from gastrointestinal neuroendocrine tumours: The FFCD 1104-EVACEL-GTE phase II study.

BACKGROUND: Hepatic arterial embolisation therapy (HAET) is a treatment of liver metastases of gastrointestinal neuroendocrine tumours (GI-NETs). HAET increases circulating vascular endothelial growth factor levels. Everolimus is a treatment in NETs that may have antiangiogenic activity. METHODS: This phase II study was conducted in patients with predominant and progressive liver metastases from GI-NETs. Everolimus was initiated 7-30 days after HAET. The hypothesis was that everolimus after HAET would increase hepatic progression-free survival (hPFS) rate at 24 months from 35% to 50%. RESULTS: Among the 74 patients included, 88% had small-bowel primary tumour, 43% had grade I and 57% grade II tumour, and 51% had extrahepatic metastases. Patients underwent one (n = 19), two (n = 54), or three (n = 1) HAET procedures. hPFS at 24 months was 33% (95% confidence interval [CI], 22.5-43.7); 40 (54%) patients had objective response. Median (95% CI) hPFS, PFS, and overall survival were 19 (14-23), 17 (13-22), and 51 (33-60) months. The most common grade III-IV toxicities (>5%) in patients receiving both HAET and everolimus (n = 67) were elevated liver enzymes (55%), fatigue (18%), diarrhoea (16%), anaemia (12%), hypertriglyceridaemia (7%) and mucositis (6%). CONCLUSIONS: The primary end-point was not reached. This sequence allows high liver response with HAET, and everolimus controls the extrahepatic disease.

High Prevalence of Anal Canal High-Risk Human Papillomavirus Infection in Patients With Crohn's Disease.

BACKGROUND & AIMS: The increasing incidence of anal canal carcinomas requires better knowledge on anal human papillomavirus (HPV) infection. We aimed to assess anal canal HPV infection prevalence and risk factors among patients seen at a gastroenterology department in France. METHODS: We analyzed anal tissue samples collected from 469 consecutive patients (median age 54 years, 52% women), including 112 who received immunosuppressant therapies and 101 with inflammatory bowel disease (70 with Crohn's disease), who underwent colonoscopy examinations from April 1, 2012 to April 30, 2015. HPV was detected and genotyped using the INNO-LiPA assay, and we collected medical and demographic data from all subjects. Risk factors for any HPV, high-risk HPV (HR-HPV) and HPV16 infection were assessed by bivariate and multivariate analysis. The primary outcomes association of HR-HPV or HPV16 with medical and demographic features. RESULTS: We detected HPV DNA in anal tissues from 34% of the subjects and HR-HPV in 18%. HPV16 was the most prevalent genotype (detected in 7%), followed by HPV51, HPV52, and HPV39. HR-HPV was detected in a significantly higher proportion of samples from women (23.1%) than men (12.8%) (P = .0035); HR-HPV and HPV16 were detected in a significantly higher proportion of patients with Crohn's disease (30.0%) than without (18.1%) (P = .005). Female sex, history of sexually transmitted disease, lifetime and past year-number of sexual partners, active smoking, and immunosuppressive therapies were independent risk factors for anal HR-HPV infection in multivariate analysis. CONCLUSION: One third of patients who underwent colonoscopy at a gastroenterology department were found to have anal canal HPV infection. We detected HR-HPV infection in almost 20% of patients and in a significantly higher proportion of patients with Crohn's disease than without. Increasing our knowledge of HPV infection of anal tissues could help physicians identify populations at risk and promote prophylaxis with vaccination and adequate screening.

Overall Survival Prediction and Usefulness of Second-Line Chemotherapy in Advanced Pancreatic Adenocarcinoma.

Background: In advanced pancreatic ductal adenocarcinoma (aPDAC), there is no consensual strategy for second-line chemotherapy (L2). Better discrimination of overall survival (OS) may help clinical decision-making. We aimed to predict OS from the beginning of L2 and to assess the benefit from chemotherapy among the identified risk groups. Methods: Analyses were derived from all consecutive aPDAC patients treated at Besancon University Hospital, Besancon, France, between January 2003 and December 2013 (n = 462). The association of 50 parameters with OS was evaluated using univariate and multivariable Cox analyses. Based on the final model, a prognostic nomogram and score were developed and externally validated. Patients in the external validation cohort who received L2 (n = 163) were treated at three French institutions between January 2010 and April 2016. All statistical tests were two-sided. Results: In the development cohort, 395 patients (85.5%) were eligible for L2, of which 261 (66.1%) were treated. Age, smoking status, liver metastases, performance status, pain, jaundice, ascites, duration of first-line, and type of L2 regimen were identified as independent prognostic factors for OS in L2. The score determined three groups with median OS of 11.3 months (95% confidence interval [CI] = 9.1 to 12.9 months), 3.6 months (95% CI = 2.6 to 4.7 months), and 1.4 months (95% CI = 1.2 to 1.7 months), for low-, intermediate-, and high-risk groups, respectively ( P < .001). By applying the score in the population eligible for L2 but untreated, the chemotherapy benefit was statistically significant across all groups, but with a magnitude of the effect decreased statistically significantly from low- to high-risk groups ( P = .001 for treatment and risk groups interaction term). The ability of the score to discriminate OS was confirmed in the external validation cohort. Conclusions: This prognostic nomogram and score in patients with aPDAC can accurately predict OS before administration of L2 and may help clinicians in their therapeutic decisions.

Sequential FOLFIRI.3 + Gemcitabine Improves Health-Related Quality of Life Deterioration-Free Survival of Patients with Metastatic Pancreatic Adenocarcinoma: A Randomized Phase II Trial.

BACKGROUND: A randomized multicenter phase II trial was conducted to assess the sequential treatment strategy using FOLFIRI.3 and gemcitabine alternately (Arm 2) compared to gemcitabine alone (Arm 1) in patients with metastatic non pre-treated pancreatic adenocarcinoma. The primary endpoint was the progression-free survival (PFS) rate at 6 months. It concludes that the sequential treatment strategy appears to be feasible and effective with a PFS rate of 43.5% in Arm 2 at 6 months (26.1% in Arm 1). This paper reports the results of the longitudinal analysis of the health-related quality of life (HRQoL) as a secondary endpoint of this study. METHODS: HRQoL was evaluated using the EORTC QLQ-C30 at baseline and every two months until the end of the study or death. HRQoL deterioration-free survival (QFS) was defined as the time from randomization to a first significant deterioration as compared to the baseline score with no further significant improvement, or death. A propensity score was estimated comparing characteristics of partial and complete responders. Analyses were repeated with inverse probability weighting method using the propensity score. Multivariate Cox regression analyses were performed to identify independent factors influencing QFS. RESULTS: 98 patients were included between 2007 and 2011. Adjusting on the propensity score, patients of Arm 2 presented a longer QFS of Global Health Status (Hazard Ratio: 0.52 [0.31-0.85]), emotional functioning (0.35 [0.21-0.59]) and pain (0.50 [0.31-0.81]) than those of Arm 1. CONCLUSION: Patients of Arm 2 presented a better HRQoL with a longer QFS than those of Arm 1. Moreover, the propensity score method allows to take into account the missing data depending on patients' characteristics. TRIAL REGISTRATION INFORMATION: Eudract N° 2006-005703-34.

FOLFOX as second-line chemotherapy in patients with pretreated metastatic pancreatic cancer from the FIRGEM study.

BACKGROUND: FOLFOX second-line treatment seems to be a validated option for patients with pancreatic cancer (PC) progressing after gemcitabine chemotherapy. However, other therapeutics strategy has developed in first-line therapy, as the FIRGEM phase II study that evaluated gemcitabine alone versus FOLFIRI.3 alternating with gemcitabine every two months. The present study assessed the efficacy and safety of FOLFOX after failure of the first-line therapy used in the FIRGEM study. METHODS: In this prospective observational cohort study, we analysed all consecutive patients who received second-line chemotherapy with FOLFOX among 98 patients with metastatic PC included in the FIRGEM study. Progression-free survival (PFS) and overall survival (OS) were estimated from the start of second-line chemotherapy using the Kaplan-Meier method. RESULTS: Among 46 patients who received second-line chemotherapy, 27 patients (male, 55%; median age, 61 years; performance status (PS) 0-1, 44%) were treated with FOLFOX after progression to first-line gemcitabine alone (n = 20) or FOLFIRI.3 alternating with gemcitabine (n = 7). Grade 3 toxicity was observed in 33% of patients (no grade 4 toxicity). At the end of follow-up, all patients had progressed and 25 had died. No objective response was observed, and disease control rate was 36%. Median PFS and OS were 1.7 and 4.3 months, respectively. In multivariate analysis, PS was the only independent prognostic factor. For patients PS 0-1 versus 2-3, median PFS was 3.0 versus 1.2 months (log rank, p = 0.002), and median OS was 5.9 versus 2.6 months (log rank, p = 0.001). CONCLUSIONS: This study suggests that FOLFOX second-line therapy offered interesting efficacy results with an acceptable toxicity profile in metastatic PC patients with a good PS.

Treatment of ulcerative colitis refractory to steroid therapy by oral microemulsion cyclosporine (Neoral).

BACKGROUND: Intravenous cyclosporine is active in 60% to 80% of patients with ulcerative colitis (UC) who failed to respond to intravenous corticosteroids. Several studies have suggested that cyclosporine in microemulsion form (Neoral) has some efficacy in this setting, but the optimal dose, blood level, time to response, and remission need to be better defined. The aim of this study was to evaluate the response to Neoral and its toxicity in active corticosteroid-refractory UC. METHODS: Between March 2002 and August 2005, 20 courses of Neoral [initial dose, 2.3 mg/kg (range, 1.8 to 2.8 mg/kg) every 12 hours] were prescribed in 19 consecutive patients for a UC attack that did not respond to intravenous methylprednisolone. All patients received prophylaxis against Pneumocystis carinii. RESULTS: Response was obtained in 17 of 20 attacks (85%) after 3.5 days (range, 1 to 7). Remission was obtained in 15 of 20 attacks (75%) after 13 days (range, 2 to 30 days). Four responders relapsed and underwent colectomy 21 to 900 days after the start of Neoral. Overall, 14 of 19 patients (74%) were colectomy free after a median follow-up of 8 months (range, 1 to 41 months). Cyclosporine blood levels were measured at fasting (C0) and 2 hours after Neoral administration (C2) in a subgroup of 10 responders. The results were 103 ng/mL (range, 32 to 240 ng/mL) for C0 and 761 ng/mL (183 to 1390 ng/mL) for C2. One severe bedridden patient with neonatal encephalopathy died. Main side effects observed were mild transient renal impairment (n = 2), hypertension (n = 1), cytomegalovirus infection (n = 2), and esophageal candidiasis (n = 1). CONCLUSIONS: In active corticosteroid-refractory UC, Neoral seems to have the same efficacy and toxicity as the intravenous form. Trough target cyclosporine blood levels should not exceed 100 ng/mL for C0 and 700 ng/mL for C2.
