Gastric Cancer: Are There New Therapeutic Options?

August 01, 2007

The majority of patients who undergo resection for gastric cancer experience relapse and ultimately die of their disease. Therefore, considerable attention has been paid to neoadjuvant and adjuvant strategies to improve surgical outcomes. Two different approaches have been tested in major clinical trials conducted in the past several years: Postoperative chemoradiotherapy was assessed in a US Southwest Oncology Group/Intergroup study (SWOG 9008/INT 0116), and perioperative chemotherapy was studied in a UK Medical Research Council (MRC) randomized trial (the MRC Adjuvant Gastric Infusional Chemotherapy [MAGIC] trial). These trials demonstrated statistically significant survival benefits in patients with resectable gastric cancer. This review will consider these trials and their implications for clinical practice.

Pancreatic Cancer: Epidemiology, Genetics, and Approaches to Screening

December 01, 2002

The review by Drs. Konner and O’Reilly addresses a number of important issues in pancreatic cancer. Adenocarcinoma of the pancreas is a devastating disease,[1] not only because it will occur in approximately 30,000 Americans this year, and perhaps 200,000 people worldwide, but also because of its high associated mortality. Pancreatic adenocarcinoma is one of the least treatable and, therefore, most lethal of all cancers. Fully 95% of all patients with an established diagnosis of adenocarcinoma of the pancreas will die of their disease.

Commentary (Macdonald)-Adjuvant Therapy for Gastric Carcinoma: Closing out the Century

November 01, 1999

Yao and colleagues present a concise, yet complete review and analysis of adjuvant therapeutic approaches for gastric adenocarcinoma. They confirm a fact known to all clinical oncologists who manage patients with resected gastric cancer: No adequate data support the value of postoperative (adjuvant) or preoperative (neoadjuvant) therapy in managing patients with locally advanced adenocarcinoma of the stomach.

Toxicity of 5-Fluorouracil

July 01, 1999

Fluorouracil (5-FU) is a relatively unique drug in oncology because administration in different doses and schedules results in dramatically different patterns of qualitative toxicity. In the 41 years 5-FU has been

Seeds, External Beam RT Equally Effective in Early-Stage Disease

December 01, 1998

PHOENIX-For many men with early-stage prostate cancer, the choice between external beam radiotherapy and brachytherapy (seed implantation) can be made based solely on lifestyle issues and personal preference, according to results of a study reported at the 40th Annual Meeting of the American Society for Therapeutic Radiology and Oncology.
