Perioperative chemotherapy with FOLFOX4 and surgery versus surgery alone for resectable liver metastases from colorectal cancer (EORTC Intergroup trial 40983): a randomised controlled trial.

ABSTRACT: Surgical resection alone is regarded as the standard of care for patients with liver metastases from colorectal cancer, but relapse is common. We assessed the combination of perioperative chemotherapy and surgery compared with surgery alone for patients with initially resectable liver metastases from colorectal cancer.This parallel-group study reports the trial's final data for progression-free survival for a protocol unspecified interim time-point, while overall survival is still being monitored. 364 patients with histologically proven colorectal cancer and up to four liver metastases were randomly assigned to either six cycles of FOLFOX4 before and six cycles after surgery or to surgery alone (182 in perioperative chemotherapy group vs 182 in surgery group). Patients were centrally randomised by minimisation, adjusting for centre and risk score. The primary objective was to detect a hazard ratio (HR) of 0.71 or less for progression-free survival. Primary analysis was by intention to treat. Analyses were repeated for all eligible (171 vs 171) and resected patients (151 vs 152). This trial is registered with ClinicalTrials.gov, number NCT00006479.In the perioperative chemotherapy group, 151 (83%) patients were resected after a median of six (range 1-6) preoperative cycles and 115 (63%) patients received a median six (1-8) postoperative cycles. 152 (84%) patients were resected in the surgery group. The absolute increase in rate of progression-free survival at 3 years was 7.3% (from 28.1% [95.66% CI 21.3-35.5] to 35.4% [28.1-42.7]; HR 0.79 [0.62-1.02]; p=0.058) in randomised patients; 8.1% (from 28.1% [21.2-36.6] to 36.2% [28.7-43.8]; HR 0.77 [0.60-1.00]; p=0.041) in eligible patients; and 9.2% (from 33.2% [25.3-41.2] to 42.4% [34.0-50.5]; HR 0.73 [0.55-0.97]; p=0.025) in patients undergoing resection. 139 patients died (64 in perioperative chemotherapy group vs 75 in surgery group). Reversible postoperative complications occurred more often after chemotherapy than after surgery (40/159 [25%] vs 27/170 [16%]; p=0.04). After surgery we recorded two deaths in the surgery alone group and one in the perioperative chemotherapy group.Perioperative chemotherapy with FOLFOX4 is compatible with major liver surgery and reduces the risk of events of progression-free survival in eligible and resected patients.

Project description:BackgroundEfforts to improve the outcome of liver surgery by combining curative resection with chemotherapy have failed to demonstrate definite overall survival benefit. This may partly be due to the fact that these studies often involve strict inclusion criteria. Consequently, patients with a high risk profile as characterized by Fong's Clinical Risk Score (CRS) are often underrepresented in these studies. Conceptually, this group of patients might benefit the most from chemotherapy. The present study evaluates the impact of neo-adjuvant chemotherapy in high-risk patients with primary resectable colorectal liver metastases, without extrahepatic disease. Our hypothesis is that adding neo-adjuvant chemotherapy to surgery will provide an improvement in overall survival (OS) in patients with a high-risk profile.Methods/designCHARISMA is a multicenter, randomized, phase III clinical trial. Patients will be randomized to either surgery alone (standard treatment, arm A) or to 6 cycles of neo-adjuvant oxaliplatin-based chemotherapy, followed by surgery (arm B). Patients must be ≥ 18 years of age with liver metastases of histologically confirmed primary colorectal carcinoma. Patients with extrahepatic metastases are excluded. Liver metastases must be deemed primarily resectable. Only patients with a CRS of 3-5 are eligible. The primary study endpoint is OS. Secondary endpoints are progression free survival (PFS), quality of life, morbidity of resection, treatment response on neo-adjuvant chemotherapy, and whether CEA levels can predict treatment response.DiscussionCHARISMA is a multicenter, randomized, phase III clinical trial that will provide an answer to the question if adding neo-adjuvant chemotherapy to surgery will improve OS in a well-defined high-risk patient group with colorectal liver metastases.Trial registrationThe CHARISMA is registered at European Union Clinical Trials Register (EudraCT), number: 2013-004952-39 , and in the "Netherlands national Trial Register (NTR), number: 4893.

Project description:Background10-20% of patients with gastric cancer (GC) have HER2+ tumors. Addition of trastuzumab (T) to cisplatin/fluoropyrimidine-based chemotherapy (CT) improved survival in metastatic, HER2+ GC. When pertuzumab (P) was added to neoadjuvant T and CT, a significant increase in histopathological complete response rate was observed in HER2+ breast cancer. This study aims to investigate the added benefit of using both HER2 targeting drugs (T alone or the combination of T + P), in combination with perioperative CT for localized HER2+ GC.MethodsThis is a prospective, randomized, open-label, phase II trial. HER2 status from patients with resectable GC (UICC TNM7 tumor stage Ib-III) will be centrally determined. Two hundred and-fifteen patients from 52 sites in 14 countries will be centrally randomized (1:2:2 ratio) to one of the following treatment arms: 1. Standard: CT alone. CT regimens will be FLOT (5-FU, leucovorin, oxaliplatin, taxotere) CapOx (capecitabine, oxaliplatin) or FOLFOX (5-FU, leucovorin, oxaliplatin) according to investigator's choice in Europe, and cisplatin/capecitabine in Asia. 2. Experimental arm 1: CT as in control group, plus T (8 mg/kg loading dose, followed by 6 mg/kg every 3 weeks) at day 1, independent of CT chosen for 3 cycles of 3 weeks before and after surgery. 3. Experimental arm 2: CT plus T as in experimental arm 1, plus P (840 mg every 3 weeks) on day 1. Adjuvant treatment with T or T + P will continue for 17 cycles in total. Stratification factors are: histology (intestinal/non-intestinal); region (Asia vs Europe); location (GEJ vs non-GEJ); HER2 immunohistochemistry score (IHC 3+ vs IHC 2+/FISH+) and chemotherapy regimen. Primary objective is to detect an increase in the major pathological response rate from 25 to 45% either with CT plus T alone, or with CT plus the combination of T and P.DiscussionDepending on the results of the INNOVATION trial, the addition of HER2 targeted treatment with either T or T and P to CT may inform future study designs or become a standard in the perioperative management HER2+ GC.Trial registrationThis article reports a health care intervention on human participants and was registered on July 10, 2014 under ClinicalTrials.gov identifier: NCT02205047 ; EudraCT: 2014-000722-38.

Project description:ImportanceClinical outcomes after curative treatment of resectable pancreatic ductal adenocarcinoma (PDA) remain suboptimal. To assess the potential of early control of systemic disease with multiagent perioperative chemotherapy, we conducted a prospective trial.ObjectiveTo determine 2-year overall survival (OS) using perioperative chemotherapy for resectable PDA.Design, setting, and participantsThis was a randomized phase 2 trial of perioperative chemotherapy with a pick-the-winner design. It was conducted across the National Clinical Trials Network, including academic and community centers all across the US. Eligibility required patients with Zubrod Performance Score of 0 or 1, confirmed tissue diagnosis of PDA, and resectable disease per Intergroup criteria.InterventionsPerioperative (12 weeks preoperative, 12 weeks postoperative) chemotherapy with either fluorouracil, irinotecan, and oxaliplatin (mFOLFIRINOX, arm 1) or gemcitabine/nab-paclitaxel (arm 2).Main outcomes and measuresThe primary outcome was 2-year overall survival (OS), using a pick-the-winner design; for 100 eligible patients, accrual up to 150 patients was planned to account for cases deemed ineligible at central radiology review.ResultsFrom 2015 to 2018, 147 patients were enrolled; 43 patients (29%) had ineligible disease, beyond resectability criteria, at central radiology review. There were 102 eligible and evaluable patients, 55 in arm 1 and 47 in arm 2, of whom the median (range) age was 66 (44-76) and 64 (46-76) years, respectively; 36 patients (65%) in arm 1 and 24 (51%) in arm 2 were men. In arm 1, 34 (62%) had Zubrod Performance Score of 0, while in arm 2, 31 (66%) did; and 44 (80%) in arm 1 and 39 (83%) in arm 2 had head tumors. Of 102 patients, 84% and 85% completed preoperative chemotherapy, 73% and 70% underwent resection, and 49% and 40% completed all treatment. Adverse events were expected hematologic toxic effects, fatigue, and gastrointestinal toxicities. Two-year OS was 47% (95% CI, 31%-61%) for arm 1 and 48% (95% CI, 31%-63%) for arm 2; median OS was 23.2 months (95% CI, 17.6-45.9 months) and 23.6 months (95% CI, 17.8-31.7 months). Neither arm's 2-year OS estimate was significantly higher than the a priori threshold of 40%. Median disease-free survival after resection was 10.9 months in arm 1 and 14.2 months in arm 2.Conclusions and relevanceThis phase 2 randomized clinical trial did not demonstrate an improved OS with perioperative chemotherapy, compared with historical data from adjuvant trials in resectable pancreatic cancer. Two-year OS was 47% with mFOLFIRINOX and 48% with gemcitabine/nab-paclitaxel for all eligible patients starting treatment for resectable PDA. The trial also demonstrated adequate safety and high resectability rates with perioperative chemotherapy, and challenges in quality control for resectability criteria.Trial registrationClinicalTrials.gov Identifier: NCT02562716.
