Lessons Learned: The use of sodium levofolinate (Na-Lev) is safe in combination with continuous infusion 5-fluorouracil in patients with gastrointestinal tumors treated with the FOLFIRI regimen. A comparison with calcium levofolinate (Ca-Lev) showed a similar toxicity profile. The advantages of Na-Lev over Ca-Lev might be the faster drug preparation and the shorter time of drug administration.
Background: The objectives of this study were to compare the safety profiles of sodium levofolinate (Na-Lev) and calcium levofolinate (Ca-Lev) in combination with 5-fluorouracil (5-FU) in the FOLFIRI regimen and to measure the organizational impact of the introduction of Na-Lev on drug production and administration.
Methods: The study opened in November 2015 and closed in August 2019. Patients with gastrointestinal cancers who were candidates for treatment with the FOLFIRI regimen were included in this nonrandomized study. Age ≥18 years, life expectancy >3 months, adequate bone marrow reserve, adequate hepatic and renal function, and an ECOG performance status of 0-2 were required. Patients in the Ca-Lev arm received a 2-hour infusion of Ca-Lev followed by 5-FU, whereas those in the Na-Lev arm received Na-Lev and 5-FU administered in a single 48-hour pump.
Results: Sixty patients were enrolled, 30 in each arm. Patient characteristics were balanced. Grade (G)1-2 adverse events occurred in 18 (60.0%) and 19 (63.4%) patients of Na-Lev and Ca-Lev cohorts, respectively, whereas G3-4 adverse events occurred in 12 (40.0%) and 11 (36.6%) patients, respectively. The use of Na-Lev enabled us to save approximately 13 minutes for drug preparation and 2 hours for treatment administration, per patient per cycle.
Conclusion: Na-Lev showed a reassuring toxicity profile and a favorable impact on drug preparation and administration.

Combination of Compound Kushen injection with first-line treatment versus first-line treatment alone for advanced colorectal cancer: a study protocol for a multicenter, openlabel, randomized controlled trial.
BMC Complement Med Ther
December 2024
Oncology Department, Guang'anmen Hospital, China, Academy of Chinese Medical Sciences, Beixian Pavilion, No.5, Xicheng District, Beijing, China.
Article Synopsis
- The study focuses on assessing the effectiveness and safety of Compound Kushen Injection (CKI) when used alongside first-line treatments for advanced colorectal cancer (CRC), as current therapies yield limited results.
- Participants will be randomly assigned to either a control or treatment group, with both groups receiving standard chemotherapy while the treatment group also receives CKI to determine its impact on progression-free survival and other health outcomes.
- This trial aims to provide valuable insights that could enhance treatment options for advanced CRC patients, making it a significant contribution to cancer research.
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).
Qualitative Transcriptional Signature for Predicting the Pathological Response of Colorectal Cancer to FOLFIRI Therapy.

FOLFIRI (5-FU, leucovorin, irinotecan) is the first-line chemotherapy for metastatic colorectal cancer (mCRC), but response rates are under 50%. This study aimed to develop a predictive signature for FOLFIRI response in mCRC patients. Firstly, Spearman's rank correlation and Wilcoxon rank-sum test were used to select chemotherapy response genes and gene pairs, respectively.

Background: RECIST may not be optimal for assessing treatment response with current systemic regimens. We evaluated RECIST, morphologic, and pathologically documented response (pathological response) in patients with initially unresectable colorectal cancer liver-only metastases (CRLM).
Patients And Methods: Four hundred and eighty-nine patients from the phase III CAIRO5 trial were included who were treated with FOLFOX/FOLFIRI/FOLFOXIRI and bevacizumab or panitumumab.

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).
