Objective: This Phase II study was conducted to evaluate the effects of irinotecan plus capecitabine in patients with advanced gastric cancer (AGC) who had received a first-line therapy of 5-fluorouracil/platinum regimen.
Methods: Patients received capecitabine 1000 mg/m(2) b.i.d. on days 1-14 followed by a 7-day rest period, and irinotecan 100 mg/m(2) was administered through a 90 min intravenous infusion on days 1 and 8, based on a 3-week cycle.
Results: Forty-six (95.8%) of the 48 patients were assessable for response. Thirteen cases of partial response were confirmed, response rate of 27.1% (95% CI, 14.5-39.7%). The median follow-up period was 25.2 months. The median time to progression and overall survival for all patients were 4.1 months (95% CI, 3.4-4.8 months) and 7.6 months (95% CI, 5.1-10.1 months). Grade 3 diarrhea and hand-foot syndrome occurred in eight (17.4%) and two (4.3%) patients, respectively. The most common Grade 3/4 hematological adverse event was neutropenia in four (8.7%) patients. There were no treatment-related deaths during this study.
Conclusion: Irinotecan plus capecitabine was a relatively active and tolerable regimen as a second-line chemotherapy for AGC. Further investigation of this regimen is warranted, including the addition of new biological agents such as bevacizumab or cetuximab to improve the salvage regimen.

Value of ctDNA in surveillance of adjuvant chemosensitivity and regimen adjustment in stage III colon cancer: a protocol for phase II multicentre randomised controlled trial (REVISE trial).

Introduction: The standard of care for stage III colon cancer is 3 or 6 months of double-drug regimen chemotherapy following radical surgery. However, patients with positive circulating tumour DNA (ctDNA) exhibit a high risk of recurrence risk even if they receive standard adjuvant chemotherapy. The potential benefit of intensified adjuvant chemotherapy, oxaliplatin, irinotecan, leucovorin and fluoropyrimidine (FOLFOXIRI), for ctDNA-positive patients remains to be elucidated.

Article Synopsis
- A study explored salvage chemotherapy using capecitabine plus oxaliplatin (XELOX) for gastric cancer patients who couldn't tolerate or were resistant to cisplatin, but it was halted due to low patient enrollment.
- 12 patients participated, revealing a disease control rate of 90% and a response rate of 30%, with median progression-free survival of 4.2 months and overall survival of 7.1 months.
- Common severe side effects included fatigue and low potassium levels, but there were no treatment-related deaths, suggesting XELOX might be beneficial for these patients.
Alternating Oxaliplatin and Irinotecan Chemotherapy Combined With Capecitabine and Bevacizumab for Microsatellite-stable Stage IV Metastatic Colon Cancer With a BRAF V600E Mutation: Two Case Reports Indicating Survival Improvement over Standard Therapy.

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.

Previous studies showed encouraging efficacy of alternating FOLFOX/FOLFIRI for metastatic colorectal cancer (mCRC). This phase 2 trial (NCT04324476) aimed to evaluate efficacy and safety of alternating modified CAPOX (capecitabine and oxaliplatin)/modified CAPIRI (capecitabine and irinotecan) plus bevacizumab (anti-VEGF-A antibody) in untreated unresectable mCRC. Induction treatment included capecitabine 1000 mg/m bid D2-8 and D16-22, oxaliplatin 85 mg/m D1, irinotecan 150 mg/m D15, and bevacizumab 5 mg/kg D1 and 15 for 28-day cycles (up to six cycles).

Purpose: The ESPAC4 trial showed that adjuvant chemotherapy with gemcitabine plus capecitabine (GemCap) produced longer overall survival (OS) than gemcitabine monotherapy. Subsequently, the PRODIGE24-CCTG PA.6 trial showed even longer survival for modified fluorouracil, folinic acid, irinotecan, and oxaliplatin (mFOLFIRINOX) than gemcitabine but had more restrictive eligibility criteria.
