SAN FRANCISCO-Platinum-based chemotherapy with either gemcitabine (Gemzar) or paclitaxel (Taxol) caused fewer terminations of therapy for progressive disease or adverse events than the reference regimen of platinum with vinorelbine (Navelbine) in advanced non-small-cell lung cancer (NSCLC).
Advances in molecular virology and biotechnology have led to the engineering of vectors that can efficiently transfer genes to target cells. Gene therapy strategies were developed along two lines: Cytotoxic approaches
HOUSTON-‘‘We appear to be approaching a ceiling for benefits of cytotoxic chemotherapy in advanced non-small-cell lung cancer (NSCLC). All recent randomized studies have had similar results, and there has been no clear efficacy benefit from nonplatinum combinations or triplets. Certainly for advanced disease and even for early disease, where metastases kill most patients, a paradigm shift is needed, and that shift will probably be to targeted therapy that works against specific biologic pathways," said Roy S. Herbst, MD, PhD. Dr. Herbst is assistant professor of medicine and chief of the Section of Thoracic Oncology at the University of Texas M.D. Anderson Cancer Center in Houston, Texas.
CHICAGO-Amifostine (Ethyol) has a number of effects on transcription factors and may also mimic antitumor gene therapy by upregulating expression of manganese superoxide dismutase (MnSOD), according to David J.

As the chemotherapy horizons have expanded in colorectal cancer with development of oxaliplatin (Eloxatin) and irinotecan (CPT-11, Camptosar), so too have our approaches to therapy. Numerous immunotherapy and gene
Lamont et al have presented a very clear and concise review of current gene therapy strategies in the management of squamous cell carcinoma of the head and neck. While the presentation highlighted the most important work to date in this expanding field, it also made reference to some controversies and challenges that we are now facing. With this in mind, I would like to expand on and clarify several points raised by the authors.
Despite advances in surgery, radiotherapy, and chemotherapy, survival of patients with squamous cell carcinoma of the head and neck has not significantly improved over the past 30 years. Locally recurrent or refractory disease is particularly difficult to treat. Repeat surgical resection and/or radiotherapy are often not possible, and long-term results for salvage chemotherapy are poor. Recent advances in gene therapy have been applied to recurrent squamous cell carcinoma of the head and neck. Many of these techniques are now in clinical trials and have shown some efficacy. This article discusses the techniques employed in gene therapy and summarizes the ongoing protocols that are currently being evaluated in clinical trials. [ONCOLOGY 15(3):303-314, 2001]
