Oxaliplatin and 5-Fluorouracil in Advanced Well-Differentiated Digestive Neuroendocrine Tumors: A Multicenter National Retrospective Study from the French Group of Endocrine Tumors

International audienceIntroduction: Oxaliplatin-based regimens have shown promising antitumor activity in digestive neuroendocrine tumors (NETs); however, the available data are limited. Our aim was to assess the efficacy of FOLFOX (association of 5-fluorouracil with oxaliplatin) in a large series of patients with advanced digestive NETs. Methods: All patients with advanced digestive well-differentiated NETs treated with at least 3 cycles of FOLFOX between January 2004 and December 2018 in 12 centers from the French Group of Endocrine Tumors were included. Tumor response rate according to Response Evaluation Criteria in Solid Tumors version 1.1 criteria, progression free survival (PFS), and overall survival, as well as prognostic factors, were analyzed retrospectively. Results: One hundred fifty-five patients were included. Primary tumor locations were pancreas (n = 89), small intestine (n = 40), unknown with no evidence for lung primary (n = 13), stomach (n = 7), and rectum (n = 6). Median Ki-67 was 10%, and 65% of the tumors were grade 2. The partial response rate was 30% for pancreatic NETs, 12.5% for small intestine NETs, 38.5% for unknown primary NETs, 14% for gastric NETs, and 17% for rectal NETs. Significant prognostic factors for poor PFS after FOLFOX were progressive disease at the beginning of treatment (hazard ratio [HR] = 1.83, p = 0.007), hepatic involvement superior to 50% (HR = 2.67, p = 0.0001), and rectal primary tumor location (HR = 2.6, p = 0.0036). Among pancreatic NETs, insulinomas had a better median PFS (22 months) than other pancreatic NETs (9 months, p = 0.026) and showed a high rate (8/9) of serum glucose normalization. Conclusions: FOLFOX shows a promising antitumor activity in advanced digestive NETs. Rapid symptomatic response is observed in metastatic insulinomas

Evaluating lanreotide as maintenance therapy after first-line treatment in patients with non-resectable duodeno-pancreatic neuroendocrine tumours

International audienceIntroductionPatients with metastatic or locally advanced, non-resectable, grade 1 or 2 well-differentiated duodeno-pancreatic (WDDP) NETs are treated following European guidelines. Patients (Pts) with aggressive disease, i.e. progressive and/or symptomatic metastases and/or with significant hepatic invasion (>30–50%), and/or bone metastases, anti-tumour therapy should receive systemic combination of chemotherapy once disease control is obtained.Aim(s)The aim is to stop chemotherapy until progression. REMINET is an academic randomized, double-blind, placebo-controlled, phase II/III study designed to evaluate lanreotide (LAN) as maintenance treatment after L1 chemotherapy in G1-G2 WDDP NET.Materials and methodsMain eligibility criteria: adults pts with a metastatic (synchronous or metachronous) or locally advanced, non-resectable, grade 1 or 2 WDDP NETs and documented control disease after L1 therapy at least 4 weeks prior to randomization.Results222 patients will be randomly assigned in a 1:1 ratio to receive 120 mg LAN or placebo, every 28 days, until disease progression or unacceptable toxicity. The aim of the phase II part is to demonstrate a 6-months PFS >45% in LAN arm. Secondary endpoints are PFS according to central review, overall survival, safety and quality of life. A bio-bank of frozen blood will be constituted.ConclusionThe study is currently open in France, Germany, Belgium, United Kingdom and Ireland. A total of 25 patients are randomized (NCT02288377)

Evaluating bevacizumab in combination with FOLFIRI after the failure of platinum-etoposide regimen in patients with advanced poorly differentiated neuroendocrine carcinoma: The PRODIGE 41–BEVANEC randomized phase II study

IF 3.061International audienceIntroduction : Patients with gastroenteropancreatic (GEP), metastatic or locally advanced, non-resectable, grade 3 poorly-differentiated neuroendocrine carcinoma (NEC) are treated with cisplatin (or carboplatin)-etoposide in first-line palliative chemotherapy (CT1). However, nearly all patients will develop resistance and there is no standard second-line treatment.Aim :PRODIGE 41–BEVANEC is an academic randomized, phase II study designed to evaluate the efficacy of bevacizumab in combination with FOLFIRI after failure of CT1 in unknown primary NEC and GEP-NEC.Materials and methods : The main eligibility criteria are age ≥18 years, metastatic (synchronous or metachronous) or locally advanced, non-resectable, grade 3 GEP-NEC, and documented progressive disease during or after CT1 therapy.Results : A total of 124 patients will be randomly assigned (1:1) to receive either 5 mg/kg bevacizumab with FOLFIRI, or FOLFIRI alone, every 14 days until disease progression or unacceptable toxicity. The hypothesis is to demonstrate a 6-month overall survival for at least 50% of the patients in bevacizumab arm versus 35% in the control arm (FOLFIRI alone). Secondary endpoints are objective response, response duration, progression-free survival, toxicity, and biochemical response.Conclusion :The study is currently opened in France (NCT02820857). The first patient was randomized on September 6, 2017

Cost-Utility Analysis of Transarterial Radioembolization With Yttrium-90 Resin Microspheres Compared With Sorafenib in Locally Advanced and Inoperable Hepatocellular Carcinoma

International audiencePurpose: The SARAH (Sorafenib Versus Radioembolization in Advanced Hepatocellular Carcinoma) trial (ClinicalTrials.gov Identifier NCT01482442) did not show a significant survival benefit for patients treated with transarterial radioembolization (TARE) compared with continuous oral sorafenib. The improved toxicity profile of patients treated with TARE in the trial, however, could result in a quality of life benefit in economic evaluations. Our objective was to perform a cost-utility analysis of TARE versus sorafenib for locally advanced and inoperable hepatocellular carcinoma.Methods: This study used patient-level data of the SARAH trial regarding resource use, progression-free and overall survival, and quality of life for the within-trial period for the patients who received at least 1 dose of sorafenib or 1 treatment with TARE according to their randomization arm. Data were extrapolated by using a partitioned survival model that incorporated costs and health outcomes, measured in life-years and quality-adjusted life-years (QALYs).Findings: The use of TARE resulted in an average loss of 0.036 life-year and a gain of 0.006 QALY compared with sorafenib. The aerage cost for the TARE arm was €17,179 (95% CI, 9,926-24,280) higher than the sorafenib arm, for an incremental cost-effectiveness ratio of €3,153,086/QALY. The probabilistic sensitivity analysis revealed a 50% risk that the TARE strategy was dominated. TARE was consistently dominated by sorafenib or had an incremental cost-effectiveness ratio more than €450,000/QALY in all sensitivity analyses.Implications: This economic evaluation of SARAH found that using radioembolization with yttrium-90 microspheres for the treatment of hepatocellular carcinoma was not a cost-effective option at the usually accepted willingness-to-pay thresholds
