Acute methotrexate toxicity managed with leucovorin and pegylated granulocyte colony-stimulating factor: A report of two cases and review of literature

Clinical Dermatology Review
Acute methotrexate (MTX) toxicity is most commonly due to overdose of the drug, which may be due to the patient's noncompliance to doctor's orders or physician's prescription error. Other causes include acute renal failure, concomitant use of other drugs,

Daraxonrasib and Beyond: Pan‐RAS Inhibition, Resistance, and Next‐Generation Strategies

Cancer Science, EarlyView.
ABSTRACT RAS proteins have long been considered difficult therapeutic targets, but allele‐selective inhibitors established the clinical tractability of mutant RAS. Daraxonrasib (RMC‐6236), an oral pan‐RAS inhibitor, has now extended this concept by targeting multiple mutant and wild‐type RAS proteins.

Retrospective analysis of cases with low dose methotrexate-induced neutropenia

Ulusal Romatoloji Dergisi
Objective: Low dosemethotrexate (MTX) is among the most commonly used drugs in rheumatology and rarely associated with neutropenia. It is generally observed as a result of improper use or in patients with risk factors for toxicity.

Eruptive Acral Melanocytic Lesions Associated With Capecitabine

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Eruptive nevi and lentigines have been reported to occur in the setting of immunosuppression, which may be medication‐induced. The associated histopathologic findings have not been well described in the literature. Herein, we report the case of a woman in her 60s who had been receiving chemotherapy treatment with capecitabine, a prodrug of 5 ...

Folate pathway genes linked to mitochondrial biogenesis and respiration are associated with outcome of patients with stage III colorectal cancer

Tumor Biology, 2019
5-fluorouracil in combination with the folate leucovorin is the cornerstone in treatment of colorectal cancer. Transport of leucovorin into cells, and subsequent metabolic action, require expression of several genes.

Predictive Biomarkers in Metastatic Colorectal Cancer Patients Treated With Bevacizumab: A Turkish Oncology Group (TOG) Study

International Journal of Cancer, Volume 159, Issue 8, Page 2075-2083, 15 October 2026.
Bevacizumab added to systemic chemotherapy remains a cornerstone of metastatic colorectal cancer treatment, but its effectiveness is variable. Tumors can bypass the VEGF blockade by activating other pro‐angiogenic pathways, hampering the identification of predictive biomarkers.

Plasma PlGF as a Potential Biomarker in Ramucirumab‐Based Second‐Line Therapy for Advanced Gastroesophageal Adenocarcinoma: Exploratory Biomarker Analysis from the Phase II Part of the RAMIRIS Trial

International Journal of Cancer, Volume 159, Issue 7, Page 1817-1828, 1 October 2026.
Antiangiogenic treatment with ramucirumab is a standard second‐line option in advanced gastric and gastroesophageal junction adenocarcinoma. However, reliable biomarkers are currently lacking. This exploratory biomarker analysis of the RAMIRIS trial suggests that elevated baseline and early on‐treatment levels of the pro‐angiogenic placental growth ...

Activity of 5, 10-Methenyltetrahydrofolate Synthetase in Rat Tissues and in Tumor Cell Lines

Pteridines, 1990
The enzyme 5.1O-methenyltetrahydrofolate synthetase catalyzes the key enzymatic reaction in the pathway by which 5-formyl tetrahydrofolate (leucovorin) enters the folate coenzyme pool.

Efficacy and Safety Profile of a Rituximab, Methotrexate, and Thiotepa‐Based Regimen in Newly Diagnosed Primary CNS Lymphoma

International Journal of Cancer, Volume 159, Issue 6, Page 1499-1509, 15 September 2026.
Primary central nervous system diffuse large B‐cell lymphoma (PCNS‐DLBCL) lacks an optimal first‐line induction strategy, particularly for older patients and those ineligible for intensive consolidation. In this retrospective cohort of 36 newly diagnosed patients, the rituximab + methotrexate + thiotepa (RMT) regimen as first‐line induction achieved ...

Transcriptome‐Based Classification of Resected Pancreatic Ductal Adenocarcinoma Enhances Prognostic Modelling Accuracy of Overall Survival Following Adjuvant Treatment

International Journal of Cancer, Volume 159, Issue 5, Page 1322-1336, 1 September 2026.
Outcomes after resection of pancreatic ductal adenocarcinoma remain highly variable, and existing prognostic models lack sufficient accuracy. Here, the authors aimed to improve survival prediction by integrating transcriptome‐based subtyping into a validated clinical model and applying it to a multicenter real‐world cohort of fresh‐frozen resection ...
