Randomized Controlled Trial Clinical Trial
Oral granisetron for the prevention of acute late onset nausea and vomiting in patients treated with moderately emetogenic chemotherapy.
To demonstrate the efficacy of oral granisetron 1 mg twice daily for the prevention of late onset nausea and vomiting after moderately emetogenic chemotherapy that includes cyclophosphamide, carboplatin, or doxorubicin. ⋯ Oral granisetron is well tolerated and more effective than prochlorperazine in preventing nausea and vomiting for up to 48 h following treatment with moderately emetogenic chemotherapy.

The concept of targeted therapy for patients with advanced cancer has intrigued researchers for many years. The lymphoid malignancies are particularly good candidates for this therapeutic approach, due to the identification of multiple lymphocyte-specific antigens. The recent introduction of rituximab marks the beginning of a new era in the treatment of lymphoid malignancies. ⋯ Within the next 12 months, several additional monoclonal antibodies will be available for the treatment of lymphoid malignancies. These include the radioimmunoconjugates tositumomab (Bexxar) and ibritumomab (Zevalin), as well as Campath-1H (anti-CD52) monoclonal antibody. Early clinical data with each of these agents are also briefly reviewed.

Temozolomide (TMZ) is the first new chemotherapy agent to be approved for the treatment of high-grade malignant gliomas in more than 20 years. This novel oral alkylating agent has demonstrated promising activity not only in brain tumors, but in a variety of solid tumors, including malignant melanoma. TMZ is 100% bioavailable when taken orally and, because of its small size and lipophilic properties, it is able to cross the blood-brain barrier. ⋯ More importantly, there is evidence to suggest that TMZ-treated patients have a lower incidence of central nervous system relapse compared with dacarbazine-treated patients. Therefore, TMZ is actively being investigated for the treatment and prevention of brain metastases in melanoma patients. TMZ may become an important part of treatment regimens for advanced metastatic melanoma.
