Combination of gemcitabine and cetuximab in patients with advanced cholangiocarcinoma: a phase II study of the Belgian Group of Digestive Oncology

Background: Cholangiocarcinomas are uncommon tumours with a poor prognosis, that frequently present epidermal growth factor receptor overexpression. Methods: In a multi-centre phase II trial, patients with unresectable cholangiocarcinoma, naïve to chemotherapy, received Cetuximab (400 mg/m2 at week 1, then 250 mg/m2/week) and Gemcitabine (1 g/m2 on day 1, 8 and 15 every 4 weeks). Primary end point was progression-free survival (PFS) rate at 6 months, using a Simon 2-stage design. Moreover, we assessed the impact of KRAS status and skin toxic effect on efficacy. Results: Forty-four patients (41% locally advanced/59% metastatic) were enrolled. Median age was 61.5 years; ECOG PS was 0 (68%) or 1. Six months PFS reached 47%. Median OS was 13.5 months [95% confidence interval (CI) 9.8-31.8 months]. Nine patients (20.4%) had PR and disease-control rate was 79.5%. Grade 3/4-related toxic effects were haematological (52.2%), skin rash (13.6%) and fatigue (11.4%). KRAS mutations were found in 7 of 27 patients and had no influence on PFS. Skin toxic effect =grade 2 was associated with increased PFS (P = 0.05).Conclusion(s): Our study met its primary end point, suggesting that Gemcitabine-Cetuximab has activity in cholangiocarcinoma. KRAS status was not associated with PFS, unlike skin toxic effect, which could be used as a surrogate marker for efficacy

In Deciphering the Future of Adjuvant Treatment in Colon Cancer, the Journey Matters More than the Achievements

The development of adjuvant treatment in colon cancer has followed the same paradigm as in other solid tumors, transposing the drug regimens found to perform the best in the advanced setting into the adjuvant setting. However, despite numerous studies, no progress has been recorded for patients with stage II and III colon cancer since the publication of the MOSAIC trial more than 10 years ago. We performed a comprehensive review of randomized phase III trials both already published and currently recruiting, and revisited the scientific rationale of adjuvant treatment in colon cancer and the philosophical roots of its development in order to challenge the current paradigms and to consider future perspectives. This analysis provides ground for new approaches based on the identification of patients unlikely to benefit from standard therapies with the aim to spare them needless toxicities and to identify a subgroup of patients who would be candidates for advanced research with new therapies.SCOPUS: re.jinfo:eu-repo/semantics/publishe

Regorafenib assessment in refractory advanced colorectal cancer: RegARd-C study protocol

Introduction: Regorafenib was recently approved for patients with pretreated advanced colorectal cancer (aCRC), despite a moderate improvement of the patients' outcome, and significant toxicities. Based on previous studies showing that early fluorodeoxyglucose-positron emission tomography (FDG-PET)-based metabolic response assessment (MRA) might adequately select patients unlikely to benefit from treatment, the RegARd-C trial uses early MRA to identify likely non-responders to regorafenib in a population of patients with aCRC and guide a comprehensive evaluation of genomic and epigenetic determinants of resistance to treatment. Methods and analysis: RegARd-C is a multicentric prospective study. Its primary objective is to identify non-benefitters from regorafenib given at 160 mg/day, 3 weeks out of 4 in a population of patients with pretreated aCRC. Baseline PET is repeated at day 14 of the first treatment course. MRA is blinded for the investigators. Overall survival (OS) is the primary end point and will be correlated with metabolic parameters and (epi)genetic alterations assessed from tumour and serial blood samples. A target sample size of 105 evaluable patients (70 as derivation set and 35 as validation set), is considered as sufficient to validate an expected HR for OS of metabolic responders compared to metabolic non-responders significantly <1 (with 80% power and 1-sided 5% α in case of a true HR≤0.59 and a responders rate of 47%). Ethics and dissemination: The study was approved by the Institut Jules Bordet's competent ethics committee and complies with the Helsinki declaration or the Belgian laws and regulations, whichever provides the greatest protection for the patient, and follows the International Conference on Harmonisation E 6 (R1) Guideline for Good Clinical Practice, reference number CPMP/ICH/135/95. The protocol and the trials results, even inconclusive, will be presented at international oncology congresses, and published in peer-reviewed journals. Genomic and epigenetic data will be made available in public open data sets.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Postoperative C-reactive protein kinetics predict postoperative complications in patients treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal carcinomatosis

Background: Relatively high morbidity rates are reported after cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). However, early predictors of complications after CRS plus HIPEC have not been identified. The aim of this study was to evaluate the predictive role of early postoperative serum C-reactive protein (CRP) level (Day 2–4) for the detection of post-operative complications. Patients and methods: We performed a retrospective study including 94 patients treated with complete CRS (R1) and HIPEC for PC from various primary origins (2011–2016). Post-operative complications were recorded. The values for postoperative inflammatory markers (white blood cells [WBC] and platelet counts, CRP) were compared between the different groups. Results: CRP on post-operative days 2–4 was significantly higher in patients with than without complications (124 mg/L vs 46 mg/L; p < 0.0001) and higher in those with more major complications (162 mg/L vs 80 mg/L; p < 0.0012). WBC and platelet counts showed no difference within 5 days postoperatively. Conclusion: CRP levels, and kinetics mainly, between post-operative day 2 and 4, are decisive predictive markers of early and late post-operative complications after CRS plus HIPEC. The presence of post-operative complications should be suspected in patients with a high CRP mean, and a plateau level (days 2–4).SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Adjuvant chemotherapy for rectal cancer: Current evidence and recommendations for clinical practice

While adjuvant chemotherapy is an established treatment for pathological stage II and especially stage III colon cancer, its role in the multimodal management of rectal cancer remains controversial. As a result, there is substantial variation in the use of this treatment in clinical practice. Even among centres and physicians who consider adjuvant chemotherapy as a standard treatment, notable heterogeneity exists with regard to patient selection criteria and chemotherapy regimens. The controversy around this topic is confirmed by the lack of full consensus among national and international clinical guidelines. While most of the clinical trials do not support the contention that adjuvant chemotherapy may improve survival outcomes if pre-operative (chemo)radiotherapy is also given, these suffer from many limitations that preclude drawing definitive conclusions. Nevertheless, in the era of evidence-based medicine, physicians should be guided by the available data and refrain from extrapolating results of adjuvant colon cancer trials to inform treatment decisions for rectal cancer. Patients should be informed of the evidence gap, be given the opportunity to carefully discuss pros and cons of all the possible management options and be empowered in the decision making. In this article we review the available evidence on adjuvant chemotherapy for rectal cancer and propose a risk-adapted decisional algorithm that largely relies on informed patient preferences.SCOPUS: re.jinfo:eu-repo/semantics/publishe
