Abstract Radiopharmaceuticals have been utilized for men with advanced prostate cancer decades. Older agents, seldom used today, provided palliation bone metastatic pain. In 2013, the alpha emitter radium-223 a catalyst field by prolonging survival in castrate-resistant (mCRPC). Recently radioisotopic therapies gained further interest development and FDA approval of 177 lutetium (177Lu)-PSMA-617 (also known as Lu-177 vipivotide tetraxetan). This agent targets prostate-specific membrane...

Background: Gallbladder carcinoma (GBC) is a rare, aggressive malignancy comprising 0.5% of gastrointestinal cancers. It has poor survival outcomes due to its insidious onset, lack standardized screening, and limited therapies. Advanced-stage diagnosis with liver, lymph node, peritoneal metastasis common, while bone rare. The knowledge on in GBC case reports small series, clinical significance largely unexplored. Methods: study extracted the demographic variables patients metastatic (M1)...

BRCA1-associated protein 1 (BAP1) is a critical cell cycle and DNA damage response (DDR) regulator with mutations (mBAP1) causing functional loss. PARP inhibitors (PARPis) demonstrate synthetic lethality in mBAP1 preclinical models, independent of underlying BRCA status. This study aimed to explore the clinical activity niraparib patients advanced tumors likely harbor mBAP1.

655 Background: Neoadjuvant treatment for resectable pancreatic cancer (PDAC) is increasing in acceptability, but a standard regimen has yet to be established. The modified FOLFIRINOX (5-fluorouracil, leucovorin, oxaliplatin and irinotecan) often requires dose modifications, delays growth factor support due toxicity. Liposomal irinotecan injection (Nal-IRI) FDA-approved with well-tolerated safety profile relapsed, refractory mPDAC. This current study substitutes Nal-IRI traditional the...

Recent literature suggests an increasing use of systemic treatment in patients with advanced cancer near the end life (EOL), partially driven by adoption immune checkpoint inhibitors (ICIs). While studies have identified this trend, additional variables associated ICI at EOL are limited. Our aim was to characterize a population who received dose last 30 days life.We performed manual retrospective chart review ≥ 18 years died within receiving ICI.

For patients with localized pancreatic cancer minimal vascular involvement, optimal survivability requires a multidisciplinary approach of surgical resection and systemic chemotherapy. FOLFIRINOX is combination chemotherapy regimen that offers promising results in the perioperative metastatic settings; however, it can cause significant adverse effects. Such toxicity negatively impact some patients, resulting discontinuation or unsuitability. In an effort to reduce toxicities optimize...
