Efficacy and Safety of FOLFIRI Regimen in Elderly Versus Nonelderly Patients with Metastatic Colorectal or Gastric Cancer.

ABSTRACT: Irinotecan-based chemotherapy is a standard backbone of therapy in patients with metastatic colorectal cancer (CRC) or gastric cancer (GC). However, there is still a paucity of information concerning the efficacy and safety of irinotecan-based regimens in elderly patients.Using the patient cohort (n?=?1,545) from the UGT1A1 genotype study, we compared the efficacy and safety between elderly and nonelderly patients with metastatic CRC (n?=?934) or GC (n?=?611) who received first- or second-line FOLFIRI (irinotecan, leucovorin, and 5-fluorouracil) chemotherapy.Despite lower relative dose intensity in elderly patients, progression-free survival and overall survival were similar between elderly (age ?70 years) and nonelderly (<70 years) patients in the CRC cohort (hazard ratio [HR], 1.117; 95% confidence interval [CI], 0.927-1.345; p?=?.244, and HR, 0.989; 95% CI, 0.774-1.264; p?=?.931, respectively) and the GC cohort (HR, 1.093; 95% CI, 0.854-1.400; p?=?.479, and HR, 1.188; 95% CI, 0.891-1.585; p?=?.241, respectively). In both cohorts, febrile neutropenia (22.1% vs. 14.6% in CRC cohort and 35.2% vs. 22.5% in GC cohort) and asthenia (grade 3: 8.4% vs. 1.7% in CRC cohort and 5.5% vs. 2.9% in GC cohort) were more frequent in elderly patients. In the CRC cohort, mucositis and anorexia were more frequent in elderly patients. In the GC cohort, nausea and vomiting were less frequent in elderly patients.The efficacy of the FOLFIRI regimen was similar between elderly and nonelderly patients in both the CRC and the GC cohorts. However, special attention should be paid to elderly patients because of increased risk for febrile neutropenia and asthenia. The Oncologist 2017;22:293-303 IMPLICATIONS FOR PRACTICE: The efficacy of FOLFIRI (irinotecan, leucovorin, and 5-fluorouracil) chemotherapy in elderly patients with metastatic colorectal cancer or gastric cancer was similar to that in nonelderly patients. However, special attention should be paid to elderly patients because of the increased risk for febrile neutropenia and asthenia. These data suggest that the FOLFIRI regimen could be considered as a standard backbone of therapy in elderly patients with metastatic colorectal cancer or gastric cancer and that the clinical decision between doublet and singlet chemotherapy may not be based solely on age. However, the data require further assessment of frailty and performance status.

Project description:BackgroundRamucirumab [human vascular endothelial growth factor (VEGF) receptor-2 monoclonal antibody] + levofolinate, fluorouracil, and irinotecan (FOLFIRI) was approved for the treatment of metastatic colorectal cancer (CRC) in Japan based on the results from the phase 3 RAISE trial (NCT01183780). However, safety information of ramucirumab + FOLFIRI in the real-world setting is limited. Therefore, the present study was conducted to evaluate the safety of ramucirumab + FOLFIRI under routine clinical practice in patients with metastatic CRC (mCRC) after first-line chemotherapy.MethodsA single-arm, prospective, multicenter, non-interventional, observational study was conducted between August 2016 and May 2020. Patients with mCRC treated with ramucirumab + FOLFIRI for the first time were included. Patients were observed for 12 months from the start of ramucirumab. Data were recorded using the electronic data capture system.ResultsIn total, 362 patients with a mean age of 64.1 years were evaluated for safety, of whom 355 patients were evaluated for effectiveness. A higher proportion of the patients were males (n=200; 55.2%), had metastases and recurrent sites (n=362, 100.0%), and had received prior anti-cancer treatment (n=355; 98.1%). Approximately 83.7% (n=303) and 25.4% (n=92) of patients had medication history of bevacizumab and anti-epidermal growth factor receptor (EGFR) antibodies, respectively. Overall, 84.3% (n=305) of patients experienced any grade adverse events (AEs). Neutrophil count decreased (n=138; 38.1%), hypertension (n=58; 16.0%), and diarrhea (n=57; 15.7%) were observed frequently. The clinically relevant grade ≥3 AEs of special interest (AESIs) with >2% incidence included neutropenia (n=101; 27.9%), hypertension (n=35; 9.7%), proteinuria (n=23; 6.4%), hepatic dysfunction (n=15; 4.1%), febrile neutropenia (n=10; 2.8%), and leukopenia (n=9; 2.5%). The presence of renal disease at baseline increased the risk of proteinuria [risk ratio: 2.1; 95% confidence interval (CI): 1.1-4.2]. Three deaths were reported due to AEs, of which 1 was study treatment related. The 12-month survival rate of the ramucirumab + FOLFIRI regimen was 59%, mortality mainly (90%) occurring due to progressive disease.ConclusionsAlthough the current observational study enrolled patients with various medication history, the regimen of ramucirumab + FOLFIRI was manageable under clinical practice. No new safety concerns beyond the findings observed in previous clinical trials were reported.

Project description:BackgroundIn the cetuximab after progression in KRAS wild-type colorectal cancer patients (CAPRI) trial patients with metastatic colorectal cancer (mCRC) received 5-fluorouracil, folinic acid and irinotecan (FOLFIRI) and cetuximab in first line followed by 5-Fluorouracil, folinic acid, oxaliplatin (FOLFOX) with or without cetuximab until progression. Limited data are available on the efficacy and safety of anti-epidermal growth factor receptor (anti-EGFR) agents on elderly patients with mCRC. In the current study we evaluated the efficacy and safety of FOLFIRI plus cetuximab in age-defined subgroups.MethodsA post-hoc analysis was performed in CAPRI trial patients; outcomes (progression-free survival (PFS), overall response rate (ORR), safety) were analysed by age-groups and stratified according to molecular characterisation. 3 age cut-offs were used to define the elderly population (≥65; ≥70 and ≥75 years).Results340 patients with mCRC were treated in first line with FOLFIRI plus cetuximab. Among those, 154 patients were >65 years, 86 >70 years and 35 >75 years. Next-generation sequencing (NGS) was performed in 182 patients. Among them, 87 patients were >65 years, 46 >70 and 17 >75. 104 of 182 patients were wild type (WT) for KRAS, NRAS, BRAF, PIK3CA genes. In the quadruple WT group, 51 patients were ≥65 years; 29 were ≥70; 9 were ≥75. Median PFS was similar within the age-subgroups in the intention-to-treat population, NGS cohort and quadruple WT patients, respectively. Likewise, ORR was not significantly different among age-subgroups in the 3 populations. Safety profile was acceptable and similarly reported among all age-groups, with the exception of grade ≥3 diarrhoea (55% vs 25%, p=0.04) and neutropaenia (75% vs 37%, p=0.03) in patients ≥75 years and grade ≥3 fatigue (31% vs 20%, p=0.01) in patients <75 years.ConclusionsTolerability of cetuximab plus FOLFIRI was acceptable in elderly patients. Similar ORR and PFS were observed according to age-groups. No differences in adverse events were reported among the defined subgroups with the exception of higher incidence of grade ≥3 diarrhoea and neutropaenia in patients ≥75 years and grade ≥3 fatigue in patients <75 years.Trial registration number2009-014041-81.
