Article Abstract
Background: To compare the efficacy and safety of CAPIRI+bevacizumab (Bev) in comparison with FOLFIRI+Bev as first-line treatment for patients with metastatic colorectal cancer (mCRC).
Methods: Patients were randomised to receive either FOLFIRI plus Bev 5 mg kg(-1) every 2 weeks (Arm-A) or CAPIRI plus Bev 7.5 mg kg(-1) every 3 weeks (Arm-B).
Results: Three hundred thirty-three patients (Arm-A=167; Arm-B=166) were enrolled into the study. No difference was observed in median progression-free survival (PFS) (10.0 and 8.9 months; P=0.64), overall survival (25.7 and 27.5 months; P=0.55) or response rates (45.5 and 39.8.7%; P=0.32) for FOLFIRI-Bev and CAPIRI-Bev, respectively. Patients treated with CAPIRI-Bev presented significantly higher incidence of diarrhoea (P=0.005), febrile neutropenia (P=0.003) and hand-foot skin reactions (P=0.02) compared with patients treated with FOLFIRI-Bev. Treatment delays (P=0.05), dose reduction (P<0.001) and treatment discontinuation owing to toxicity (P=0.01) occurred more frequently in the CAPIRI-Bev arm.
Conclusion: The PFS of FOLFIRI-BEV is not superior to that observed with the CAPIRI-Bev regimen. CAPIRI-Bev has a less favourable toxicity profile, requiring dose reductions, in order to be considered as an option in first-line treatment of patients with mCRC.

In the tumour microenvironment, IL-1α promotes neoangiogenesis, matrix remodelling, tumour proliferation, chemoresistance, and metastases. Highly expressed in human colorectal cancers, IL-1α is associated with poor prognosis. XB2001, a fully human monoclonal antibody neutralizing IL-1α, was evaluated for safety and preliminary efficacy with trifluridine/tipiracil (FTD/TPI) and bevacizumab in metastatic colorectal cancer patients previously treated with oxaliplatin- and irinotecan-based chemotherapies.

Background: FOLFIRI (5-FU + leucovorin + irinotecan) plus ramucirumab is one of the standards in second-line metastatic colorectal cancer (CRC) patients progressing after treatment with oxaliplatin/fluoropyrimidine with bevacizumab, but there is no evidence on its efficacy without prior bevacizumab. Moreover, VEGF-D has not been confirmed as a predictive biomarker for ramucirumab's efficacy, either.
Methods: The RAINCLOUD study was a multicenter, single-arm, phase II trial conducted in Japan.

Article Synopsis
- Colorectal cancer is the third most common cancer, and managing unresectable metastatic cases, especially those with MSS and BRAF V600E mutation, poses significant challenges for treatment.
- Two case reports illustrate the effectiveness of an alternating chemotherapy regimen (irinotecan and oxaliplatin along with capecitabine and bevacizumab) in two patients with MSS, BRAF V600E-mutated stage IV metastatic CRC, demonstrating a partial response and dropping carcinoembryonic antigen levels.
- The study suggests that this alternating regimen offers a promising treatment strategy with improved progression-free survival compared to standard first-line therapies, making it a potential first-line option for patients with this specific type of colorectal cancer.
Second-line systemic treatment for metastatic colorectal cancer: A systematic review and Bayesian network meta-analysis based on RCT.

Background: The optimal second-line systemic treatment for metastatic colorectal cancer (mCRC) is inconclusive.
Methods: We searched PubMed, Web of Science, EMBASE, and Cochrane Library for RCTs comparing second-line systemic treatments for mCRC from the inception of each database up to February 3, 2024. Markov Chain Monte Carlo (MCMC) technique was used in this network meta-analysis (NMA) to generate the direct and indirect comparison results among multiple treatments in progression-free survival (PFS), overall response rate (ORR), overall survival (OS), complete response (CR), partial response (PR), grade 3 and above adverse events (Grade ≥ 3AE), and any adverse events (Any AE).

Aims: To analyze the long-term results of a prospective phase II trial testing intensified total neoadjuvant therapy (TNT) in patients with locally advanced rectal cancer (LARC).
Materials And Methods: Patients with histologically confirmed LARC adenocarcinoma were enrolled. Intensified TNT consisted of targeted agent (bevacizumab or panitumumab/cetuximab) plus FOLFOXIRI (5-fluorouracil, leucovorin, oxaliplatin and irinotecan) induction chemotherapy followed by intensified (oxaliplatin and 5-fluorouracil) chemoradiotherapy (CRT) and surgical resection.
