Clinical Trial
A pilot trial assessing the efficacy of paroxetine hydrochloride (Paxil) in controlling hot flashes in breast cancer survivors.
Many breast cancer survivors suffer debilitating hot flashes. Estrogen, the drug of choice in perimenopausal women, is generally not recommenced to breast cancer survivors. Nonhormonal treatments are mostly disappointing. Anecdotal reports in our institution suggested that the selective serotonin-reuptake inhibitor, paroxetine hydrochloride, might be efficacious in alleviating hot flashes. ⋯ Paroxetine hydrochloride is a promising new treatment for hot flashes in breast cancer survivors, and warrants further evaluation in a double-blind randomized placebo-controlled trial.

B-lymphoproliferative post-transplant disorder (BLPD) is a severe complication of organ and bone marrow transplantation. The reduction of immuno-suppressive therapy or surgery for localized disease may cure some BLPDs. Other therapeutic approaches such as chemotherapy and antiviral drugs are toxic and of limited efficacy. Adoptive immunotherapy with donor T-cell infusions has yielded promising results but is, at the present time, easily applicable only in bone marrow-transplanted patients. Anti-B-cell Murine monoclonal antibodies (MoAbs) have proven effective but are no longer available for human use. We report the activity of a humanized anti CD 20 Mo Ab (Rituximab-MABTHERA Roche) in 32 episodes of BLPD treated in 14 French centers. ⋯ The use of rituximab appears to be a safe and relatively efficient therapy in BLPDs. The results need to be confirmed in a prospective multicentric trial.

A retrospective analysis was performed to delineate the factors associated with response, and to determine the duration of response, in 87 patients with CD20-positive mantle-cell lymphoma (MCL) treated with Rituximab (chimeric monoclonal anti-CD20 antibody) in two prior studies. ⋯ Rituximab is active in MCL, and can induce complete responses in a minority of patients. Elevated LDH at the time of therapy, and prior therapy with alkylating agents, are associated with a significantly lower RR. The duration of response of one year is similar to that previously reported in follicular lymphoma.

Randomized Controlled Trial Clinical Trial
The effects of morphine on dyspnea and ventilatory function in elderly patients with advanced cancer: a randomized double-blind controlled trial.
Dyspnea represents a very frequent and distressing symptom in patients with advanced cancer. This study was undertaken to assess the efficacy of morphine on dyspnea and its safety for ventilatory function in elderly advanced cancer patients. ⋯ Morphine appears effective for cancer dyspnea, and it does not compromise respiratory function at the dose level used.

Ecteinascidin-743 (ET743) is a novel antitumour agent originating from the Caribbean tunicate Ecteinascidia turbinata. It has potent cytotoxic and antitumour activity and a potential new mechanism of action. The aim of the present study was to further explore the antitumour activity of ET743 in human tumour xenografts from melanoma, non-small-cell lung and ovarian cancer. ⋯ ET743 is a very effective agent in chemo-sensitive and marginal chemo-resistant xenografts, but inactive in chemo-resistant tumour xenografts. The activity of ET743 in the marginally cisplatin-resistant ovarian cancer HOC18 might indicate absence or incomplete cross-resistance against cisplatin. It is recommended to include melanoma, non-small-cell lung cancer, and ovarian cancer in phase II clinical trials and to use an intermittent schedule.
