Commentary (Crispens/Rothenberg): Epidermal Growth Factor Receptor Inhibitors for the Treatment of Epithelial Ovarian Cancer

April 01, 2005

Ovarian cancer is the deadliestof the gynecologic malignancies.Approximately threequartersof patients present with advanced-stage disease. With aggressivecytoreductive surgery followed byplatinum-based chemotherapy, mostpatients will achieve remission. Despitethis initially good response totreatment, most patients experiencerecurrence and ultimately die of theirdisease. Novel treatment strategies areneeded. Molecularly targeted therapiesoffer the promise of improvedefficacy with decreased toxicity. Inthis article, Drs. Stephanie Blank, RichardChang, and Franco Muggiapresent an excellent summary of thecurrent status of epidermal growth factorreceptor (EGFR) inhibitors in thetreatment of ovarian cancer. They describethe promise of these drugs aswell as some of the questions regardingthe best way to integrate theminto therapy for ovarian cancer.

Commentary (Yamao/Rothenberg): Coming to Grips With Hand-Foot Syndrome

August 01, 2004

Worldwide, oral fluoropyrimidineshave become attractiveoptions in the treatmentof patients with colorectal cancer.Capecitabine (Xeloda), the only commerciallyavailable oral fluorouracil(5-FU) analog in the United States,was rationally designed to provideprolonged exposure to 5-FU and togenerate 5-FU preferentially withintumor tissue.Capecitabine is absorbedunchanged through the gastrointestinalwall and is converted to 5-FU viaa three-step enzymatic cascade. It isfirst hydrolyzed in the liver by carboxylesteraseto 5'-deoxy-5-fluorocytidine(5'-DFCR). The next stepoccurs in the liver and tumor tissue,where cytidine deaminase converts5'-DFCR to 5'-deoxy-5-fluorouridine(5'-DFUR). Finally, 5'-DFUR isconverted to 5-FU by thymidinephosphorylase, which is preferentiallyexpressed in tumors

Chemotherapy for Resectable and Advanced Pancreatic Cancer

This article will review the pertinent data on the use of chemotherapy for all stages of pancreatic cancer. For patients with metastatic disease, fluorouracil (5-FU) was the standard of care for several decades until a single

Efficacy of Oxaliplatin in the Treatment of Colorectal Cancer

December 01, 2000

Colorectal cancer is one of the leading causes of cancer death. The mainstay of chemotherapy in colorectal cancer patients for the past 40 years has been fluorouracil (5-FU). Oxaliplatin (Eloxatin) is a novel platinum compound with promising activity in colorectal cancer. As a single agent, oxaliplatin has produced response rates of 12% to 24% in patients with previously untreated advanced colorectal cancer, and 10% to 11% in patients with relapsed or refractory advanced colorectal cancer. In phase II trials, oxaliplatin combined with 5-FU, with or without leucovorin, was associated with response rates of 60% and higher when used as front-line therapy, and when used in patients with relapsed or refractory advanced colorectal cancer, response rates ranged from 25% to 50%. In the front-line setting, two randomized trials of 5-FU and leucovorin, with or without oxaliplatin, demonstrated that the addition of oxaliplatin significantly increases response rate and time to tumor progression, but not survival, over 5-FU plus leucovorin alone. The reasons for this discrepancy are unclear, and several possibilities are being considered. Additional phase III trials are underway to clarify the contribution of oxaliplatin in the treatment of patients with locally advanced and metastatic colorectal cancer.
