5-fluorouracil

Background : First-line therapy’s (tx) choice between the two most efficacious approved regimens (FOLFIRINOX and Gemcitabine plus Nab-Paclitaxel - GemNab) in mPDAC is usually based on patients’ (pts) baseline characteristics... HR-DDR somatic alterations emerged as possible predictor of lower benefit from platinum-free regimens. Thus, platinum-based regimens should be preferred in this setting. Validation in wider cohorts and correlation with HR-DDR germline mutations are warranted.

TRIPLETE is a phase III trial where 435 pts with RAS/BRAF wt – per local assessment – mCRC were randomized to receive first-line FOLFOX/ panitumumab (pan) or mFOLFOXIRI/pan... In contrast to previous data, negative hyperselection both through tissue and plasma analysis failed to demonstrate a prognostic role among pMMR RAS/BRAF wt mCRC pts treated with first-line chemotherapy plus pan. The confounding effect of the associated chemotherapy is a potential explanation for this finding. Tissue and plasma analyses at baseline failed to provide fully concordant results.

The LIBImAb Study is a phase III, randomized, openlabel, comparative, multi-center trial to assess the superiority in terms of efficacy of bevacizumab versus cetuximab in combination with FOLFIRI in mCRC pts, RAS/BRAFwt on tumor tissue and RAS/BRAF mutant (RAS/BRAFmut) at liquid biopsy... These data indicate the feasibility of cfDNA-based prospective enrolment in an interventional trial using a test with a rapid TAT for screening of RAS/ BRAF status in plasma. Our preliminary findings also suggest that ctDNA testing might better recapitulate the tumor heterogeneity of mCRC pts thus complementing tissue genomic profiling.

We performed a comprehensive evaluation of liver-metastatic (LM) disease among mCRC patients enrolled in the phase II randomized AtezoTRIBE trial, that showed a modest benefit from the addition of atezolizumab (atezo) to 1st line FOLFOXIRI/bevacizumab (bev) and identified Immunoscore IC as a predictor of ICI efficacy in the proficient mismatch repair (pMMR) population... In our cohort of pMMR mCRC patients, the immune microenvironment of tumors with LM spread does not differ from that of tumors with no liver involvement. The presence or not of LM disease does not affect the efficacy of adding atezo to first-line FOLFOXIRI/bev, differently than Immunoscore IC.

The kidneys from rats co-treated with lycopene (10 mg) + 5-FU did not show the degenerative changes in the glomerular tufts and tubules observed for the rats treated with 5-FU alone. In conclusion, LYC is a promising therapeutic strategy for attenuating 5-FU-induced nephrotoxicity through the restoration of antioxidant activities and inhibition of inflammatory responses by modulating PPAR-γ, Nrf2/HO-1, and NF-κB/TNF-α/IL-6, signals.

The overall prognosis of BRAF V600E mutant mCRC patients is poor. Poor differentiation and liver metastases were negative independent prognostic factors for OS. First-line triplet-drug therapy was associated with better OS, especially in patients with good physical condition and high tumor burden.

Neoadjuvant cadonilimab plus FLOT chemotherapy treatment exhibits promising efficacy with manageable toxicities in locally advanced G/GEJ adenocarcinoma, providing preliminary evidence for further investigation.

This study will determine the prevalence of DPYD gene variant status in Australia and its impact on FP-induced toxicity among Australians with cancer. Feasibility and cost-effectiveness for Australian health care system will be estimated to support national roll-out of prospective DPYD genotyping prior to FP administration. Additionally, feasibility will be confirmed with the intention of including UGT1A1 in future pharmacogenomic panels to aid chemotherapy prescribing.

In Type A MSI+ tumours, the patient response to fluoropyrimidine and oxaliplatin was significantly poor (Fisher's exact test, p = 0.021)...Type A MSI was an independent predictor of patient prognosis in this pilot cohort (Cox regression analysis, p = 0.003). Thus, more subtle Type A MSI better predicts fluoropyrimidine insensitivity in colorectal cancer patients, which may shed light on a hitherto overlooked connection between the MSI phenotypes and drug resistance in human cancer.

A detail estimation of KRASG12D mut mCRC patients' characteristics and expected outcomes may be useful when planning future studies in this subgroup. The high prevalence of PI3K/PTEN/Akt pathway activating alterations may affect the efficacy of targeted strategies.

Mechanistically, aripiprazole bound to the Lys401-His404 of LAMP2a and repressed its activity, subsequently inactivating RNH1/miR-99a/mTOR signaling and inducing autophagy-mediated apoptosis, thereby suppressing tumorigenesis. Liposome-mediated delivery of aripiprazole in combination with fluorouracil elicited superior therapeutic benefits in CRC, as compared to single treatments, thereby highlighting that aripiprazole may be repurposed as a novel therapeutic agent for CRC treatment.

Compound 3c induced apoptosis, as evidenced by PARP cleavage and downregulation of p-Bcl-2 and Bcl-2, and demonstrated synergistic effects in combination with the chemotherapeutic agent 5-fluorouracil. Compound 3c also showed selectivity towards hormone-dependent breast cancer cells, likely targeting ERα - a key driver in this cancer subtype. In summary, we report the development of a first-in-class antiestrogenic isocryptolepine with notable pro-apoptotic efficacy.

The addition of trastuzumab to chemotherapy regimens improved clinical outcomes in HER2-positive gastric cancer patients. From an economic perspective, the CAPOX regimen is the most cost-effective option when considering a cost-effectiveness threshold of up to two times Iran's GDP per capita. However, when the threshold increases to three times the GDP per capita, the CAPOX + Trastuzumab regimen becomes the preferred choice. These findings provide valuable insights for healthcare policymakers in Iran.

The CRC-PDX model established in this study can maintain the biological characteristics of primary tumors and can be used as a reference model for the individualized treatment of CRC patients. The degree of malignancy of the primary tumor is the primary factor affecting the tumorigenesis rate of the PDX model.

Herein, we report extended follow-up data from the INTEGA trial (NCT03409848), which investigated the efficacy of the anti-PD-1 nivolumab, trastuzumab, and FOLFOX chemotherapy (FOLFOX arm) in comparison to a chemotherapy-free regimen involving nivolumab, trastuzumab, and the anti-CTLA-4 ipilimumab (Ipi arm) in the first-line setting for advanced disease...Furthermore, a low NLR characterized patients benefiting from immune- and targeted therapy without the need for additional chemotherapy. This data suggests that patient selection based on inflammatory stress-driven immune changes could help to customize first-line treatment in patients with advanced HER2-positive EGA to potentially improve long-term survival.

The randomized phase III POST trial aimed to compare the efficacies of two adjuvant S-1-based doublet chemotherapies: S-1 plus cisplatin (SP) and S-1 plus docetaxel (DS)...The nProfiler1 assay offers valuable insights into the prognosis and efficacy of adjuvant chemotherapy based on fluorouracil plus platinum doublet regimens but not docetaxel-containing regimens. Further validation with larger patient cohorts and different regimens is warranted.

We aim to assess the addition of XB2001 (anti-IL-1 alpha monoclonal antibody) plus trifluridine/tipiracil-bevacizumab in mCRC refractory to standard chemotherapy. This multicenter, randomized, double blind, non-comparative Phase I-II study (ClinicalTrials.gov NCT05201352) will assess the efficacy and safety of trifluridine/tipiracil-bevacizumab and XB2001 in patients with mCRC previously treated for metastatic disease by chemotherapy treatment including oxaliplatin, irinotecan, 5-FU, antiangiogenic and/or anti-EGFR if indicated...Primary end point of Phase II is the efficacy of trifluridine/tipiracil-bevacizumab + XB2001 in term of 6-month overall survival. Ancillary analysis will be performed.

Moreover, computational ADMET analyses of these compounds demonstrated compliance with Lipinski's criteria, indicating favorable physicochemical properties. Additionally, molecular dynamics (MD) simulations revealed stable complexes of AUPF01 with EGFR, CDK2, ERalfa, BAX1, BCL2, and P53, as evidenced by (RMSD) values, RMSF values, and (SASA) values for the respective complexes.

In external validation, XGBoost model achieved an accuracy of 0.79. An online prognostic tool based on XGBoost was developed, integrating metabolism-related SNPs and inflammatory markers, enhancing CRC treatment precision and supporting tailored chemotherapy.

High LINC01764 expression correlates with metastasis, a poor response to FOLFOX/XELOX chemotherapy, and a poor prognosis in CRC...LINC01764 induced 5-FU chemoresistance by upregulating the c-MYC, glucose, and glutamine metabolism pathways, which downregulated UPP1, crucial for activating 5-FU. Conclusively, LINC01764 promotes CRC progression and 5-FU resistance through hnRNPK-mediated-c-MYC IRES-dependent translational regulation, which suggests its potential as a predictor of CRC chemotherapy response and prognosis.
