A comparative characteristic of acute toxicity of toxogonine and dipiroxime is given for different animal species with various routes of introduction of the compounds from which it follows that, as concerns the toxicity parameters and the area of toxic action, toxogonine is in the lead. It is also shown that with its multiple administration in a therapeutic dose toxogonine does not affect the peripheral blood, the hepatic and renal functions, the cardio-vascular system, this being also supported by the anatomo-pathological findings. With its intramuscular introduction toxogonine does not produce any local irritation.

Background: ATR is an apical DDR kinase activated at damaged replication forks. Elimusertib is an oral ATR inhibitor and potentiates irinotecan in human colorectal cancer models.

Methods: To establish dose and tolerability of elimusertib with FOLFIRI, a Bayesian Optimal Interval trial design was pursued.

A 28-year-old woman was diagnosed with high-risk triple-expressor diffuse large B-cell lymphoma (DLBCL) (stage IV, IPI 4, CNS-IPI 5), with lymph node and extranodal involvement. The patient underwent first-line R-CHOP treatment, achieving a partial response with residual mediastinal uptake. A second-line platinum-based therapy with a transplant plan followed, resulting in stable disease; thus, she was considered refractory and started third-line therapy with CAR-T cells, receiving additional chemotherapy as bridging therapy.

Background: Immunotherapy combined with chemoradiotherapy has demonstrated promising efficacy in stage III non-small-cell lung cancer (NSCLC). However, the optimal timing for immunotherapy intervention during radiotherapy remains unclear. This study aimed to compare the efficacy and safety of immune checkpoint inhibitors (ICIs) administered concurrently or sequentially with chemoradiotherapy in unresectable stage III NSCLC.

Background: Brentuximab vedotin (BV) has demonstrated high remission rates in clinical trials for systemic anaplastic large cell lymphoma (sALCL), yet its real-world effectiveness in China remains unconfirmed. This retrospective observational study evaluates BV-based regimens in patients with sALCL, treated from 2020 to 2023.

Methods: A multi-center observational retrospective study was conducted on patients with sALCL received BV plus cyclophosphamide, doxorubicin, and prednisone (CHP) upfront or BV plus gemcitabine, oxaliplatin(GemOx), gemcitabine, cisplatin, dexamethasone(GDP), or isocyclophosphamide, carboplatin, etoposide (ICE)for later lines.

BRAF inhibitor monotherapy in BRAFV600E-mutated pediatric low-grade glioma: a single center's experience.

Front Oncol

January 2025

Department of Pediatrics, Children's Healthcare of Atlanta, Atlanta, GA, United States.

Background: Pediatric low-grade gliomas (pLGGs) have an overall survival of over 90%; however, patients harboring a BRAF alteration may have worse outcomes, particularly when treated with classic chemotherapy. Combined BRAF/MEK inhibition following incomplete resection demonstrated improved outcome in BRAF altered pLGG compared to combined carboplatin/vincristine chemotherapy and is now considered the standard FDA-approved treatment for this group of tumors. The aim herein was to investigate the efficacy and tolerability of single agent BRAF inhibitor treatment in BRAF altered pLGG.
