Oncogenic potential of tamoxifen on endometria of postmenopausal women with breast cancer--preliminary report.

Tamoxifen (TAM), a nonsteroidal antiestrogen, is used for pre- and postmenopausal patients with breast cancer. Recent reports suggest that TAM may cause endometrial neoplasia. This study is designed to evaluate the oncogenic potential of low-dose TAM on the endometrium.

Advances in chemotherapy for large cell lymphoma.

Three generations of chemotherapy regimens for the treatment of aggressive lymphomas have evolved in the past decade. The first-generation combination regimen, CVP, also known as COP (cyclophosphamide, vincristine, prednisone), produced maximum long-term survivals in considerably less than 20% of patients.
