Biomarker-Driven Therapy in Metastatic Gastric and Esophageal Cancer: Real-Life Clinical Experience.

Background: Precision treatment of cancer uses biomarker-driven therapy to individualize and optimize patient care.

Objective: To evaluate real-life clinical experience with biomarker-driven therapy in metastatic gastric and esophageal cancer in Israel.

Patients And Methods: This multicenter retrospective cohort study included patients with metastatic gastric or esophageal cancer who were treated in the participating institutions and underwent biomarker-driven therapy.

Phase 1 trial evaluating cisplatin, gemcitabine, and veliparib in 2 patient cohorts: Germline BRCA mutation carriers and wild-type BRCA pancreatic ductal adenocarcinoma.

Background: A phase 1 trial was used to evaluate a combination of cisplatin, gemcitabine, and escalating doses of veliparib in patients with untreated advanced pancreatic ductal adenocarcinoma (PDAC) in 2 cohorts: a germline BRCA1/2-mutated (BRCA+) cohort and a wild-type BRCA (BRCA-) cohort. The aims were to determine the safety, dose-limiting toxicities (DLTs), maximum tolerated dose, and recommended phase 2 dose (RP2D) of veliparib combined with cisplatin and gemcitabine and to assess the antitumor efficacy (Response Evaluation Criteria in Solid Tumors, version 1.1) and overall survival.

Phase II trial of veliparib in patients with previously treated BRCA-mutated pancreas ductal adenocarcinoma.

Purpose: BRCA-associated cancers have increased sensitivity to poly(ADP-ribose) polymerase inhibitors (PARPis). This single arm, non-randomised, multicentre phase II trial evaluated the response rate of veliparib in patients with previously treated BRCA1/2- or PALB2-mutant pancreatic adenocarcinoma (PDAC).

Methods: Patients with stage III/IV PDAC and known germline BRCA1/2 or PALB2 mutation, 1-2 lines of treatment, Eastern Cooperative Oncology Group 0-2, were enrolled.

Dexrazoxane added to doxorubicin-based adjuvant chemotherapy of breast cancer: a retrospective cohort study with a comparative analysis of toxicity and survival.

Dexrazoxane is indicated as a cardioprotective agent for patients receiving doxorubicin who are at increased risk for cardiotoxicity. Concerns have been raised on the use of dexrazoxane, particularly in adjuvant therapy, because of the risk of interference with the antitumor effect of doxorubicin. Two meta-analyses in metastatic breast cancer have rejected this hypothesis, but have shown an apparent increase in the severity of myelosuppression when dexrazoxane is used.

RNAi therapy targeting KRAS in combination with chemotherapy for locally advanced pancreatic cancer patients.

Purpose: The miniature biodegradable implant siG12D-LODER™ was inserted into a tumor and released a siRNA drug against KRAS(G12D) along four months. This novel siRNA based drug was studied, in combination with chemotherapy, as targeted therapy for Locally Advanced Pancreatic Cancer (LAPC).

Methods: An open-label Phase 1/2a study in the first-line setting of patients with non-operable LAPC was initiated.

Abdominal cocoon: a potential pitfall in patients with ovarian carcinoma.

Background. Abdominal cocoon, or sclerosing encapsulating peritonitis, is a rare condition characterized by partial or total encasement of small bowel and mesentery by a thick fibrocollagenous sack that looks like a cocoon. Within the sack, bowel loops are drawn together causing intestinal obstruction.

A 67-year-old woman with BRCA 1 mutation associated with pancreatic adenocarcinoma.

Introduction: There are approximately 40,000 new cases of pancreatic adenocarcinoma diagnosed in the USA each year. It is estimated that 5-10% of all patients with pancreatic cancer have a first-degree relative with the disease, while up to 20% of cases have a hereditary component. Individuals who carry a germline mutation in the BRCA 1 or 2 genes have an increased lifetime risk of developing pancreatic adenocarcinoma when compared with the general population.

Neoadjuvant imatinib for unresectable gastrointestinal stromal tumor.

We have evaluated the feasibility of the use of neoadjuvant imatinib mesylate in the management of unresectable localized gastrointestinal stromal tumors. In a pilot experience, two patients with unresectable gastrointestinal tumors were treated with neoadjuvant imatinib. Their treatment course and surgical outcomes are described.
