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]
BOSTON-Investigators at Johns Hopkins University School of Medicine are testing a common cold virus as a vector for gene therapy against prostate cancer, Theodore L. DeWeese, MD, reported at the 42nd annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO). The therapy was found to be safe, and the technique showed signs of antitumor activity in a phase I trial.
Patients with refractory/relapsed diffuse large B-cell non-Hodgkin’s lymphoma (NHL) who fail high-dose chemotherapy and stem cell transplant or are not suitable candidates for intensive therapy have limited therapeutic options. We have

SAN FRANCISCO-Advances in gene therapy, cancer vaccines, and a variety of new antibody therapies for hematologic malignancies were the focus of a satellite symposium to the 42nd Annual Meeting of the American Society of Hematology titled Scientific and Technical Innovations in Biology: Initiating Advances in Therapeutic Approaches to Hematological Malignancies. The program was sponsored by Fox Chase Cancer Center through an unrestricted educational grant from Genentech BioOncology and IDEC Pharmaceuticals.
WASHINGTON-Gene therapy is unlikely to cure cancer on its own, but may enhance existing treatments when used in combination, said Chuan-Yuan Li, PhD, of Duke University Medical Center. "Combining gene therapy with radiation therapy produces a synergistic effect on tumors and merits further study," he said at the Susan G. Komen Breast Cancer Foundation grants conference "Reaching for the Cure."
SAN FRANCISCO-Interim results of a trial of the combination of rituximab (Rituxan) and fludarabine (Fludara), a novel approach for the treatment of low-grade or follicular B-cell lymphoma, suggest excellent antitumor activity. Rituximab, an anti-CD20 monoclonal antibody, is the only approved monoclonal antibody therapy for refractory or relapsed low-grade or follicular non-Hodgkin’s lymphoma (NHL).

The management of non-small-cell lung cancer is undergoing rapid evolution. Although the advent of combined-modality therapy has led to improved survival, most patients eventually succumb to the disease. The arrival of a
A pilot study was performed at The University of Texas M. D. Anderson Cancer Center to determine the feasibility of using thalidomide in a population of renal-cell carcinoma patients who had progressive disease despite chemotherapy and immunotherapy. Metastatic renal-cell carcinoma patients with adequate oral function were entered onto a study after signing an internal review board-approved informed consent. There were no exclusion criteria for prior therapy. Nineteen previously treated patients and one untreated patient with progressive renal-cell carcinoma received oral thalidomide as a single agent. The starting dose was 200 mg and the dose was increased by 100 to 200 mg every week until it reached 1,200 mg/d. Response was assessed on the basis of a radiographic reduction of the metastatic sites involved. A case report describing one of the patients involved in the pilot trial is included.
