Randomized Controlled Trial Multicenter Study Clinical TrialLarynx preservation in pyriform sinus cancer: preliminary results of a European Organization for Research and Treatment of Cancer phase III trial. EORTC Head and Neck Cancer Cooperative Group.
As a general rule, surgery whenever possible, followed by irradiation is considered to be the standard treatment for cancer of the hypopharynx, thus sacrificing natural speech. In most patients, surgery includes removal of the larynx. ⋯ Larynx preservation without jeopardizing survival appears feasible in patients with cancer of the hypopharynx. On the basis of these observations, the EORTC has now accepted the use of induction chemotherapy followed by radiation as the new standard treatment in its future phase III larynx preservation trials.

Suramin-induced decrease in prostate-specific antigen expression with no effect on tumor growth in the LNCaP model of human prostate cancer.
Suramin, a polysulfonated naphthylurea and a recognized antitrypanosomal agent, has shown some promise in phase II clinical trials in the management of hormone-refractory human prostate cancer. Reduction of serum prostate-specific antigen (PSA) levels has been proposed as an end point for evaluating the antitumor efficacy of treatments for hormone-refractory prostate cancer. ⋯ PSA level should be used with caution as an end point in clinical trials using suramin therapy for hormone-refractory prostate cancer.

Cytotoxic effects of topotecan combined with various anticancer agents in human cancer cell lines.
Topotecan (TPT) is a topoisomerase I poison that exhibits antineoplastic activity. Analysis of the cytotoxic effects of combinations of TPT and other anticancer agents has been limited. ⋯ TPT cytotoxicity appears to be enhanced more by combination with certain DNA-damaging agents than by combination with antimetabolites or antimicrotubule agents. Interactions between TPT and other drugs can vary depending on the cell type examined. Further investigation is required to determine the basis of the observed effects and to determine whether these in vitro findings are predictive of results obtained in vivo.
