Clinical evaluation of two dosages and schedules of ifosfamide in combination with cisplatin in neo-adjuvant chemotherapy of patients with advanced (stage III-IV) head and neck squamous cell carcinoma: a phase II randomized study.

The aims of the present open, randomized, single-blind (patient), single institution, phase II study were: i) to compare the therapeutic effectiveness and toxicity of two dosages and schedules of ifosfamide (IFO) in combination with cisplatin (CDDP) mainly in the neo-adjuvant setting of patients (pts) with locally advanced (stage III-IV) head and neck squamous cell cancer (HNSCC) (primary endpoint); ii) to assess the quality of life (QL) of pts included in the study before and after treatment (secondary endpoint). From July 1996 to June 1997, 28 pts, all males (mean age 56.79 years, range 37-72), hospitalized in the Department of Medical Oncology, University of Cagliari, were enrolled in the study.

Medroxyprogesterone acetate and megestrol acetate reduce cisplatin-induced serotonin release from human peripheral blood mononuclear cells of cancer patients.

In the present study we evaluated the ability of either medroxyprogesterone acetate (MPA) or megestrol acetate (MA) to reduce cisplatin (CDDP)-induced serotonin (5-HT) release from peripheral blood mononuclear cells (PBMC) of cancer patients. Sixteen patients with cancer of different sites, all in advanced stage of disease, were studied (10 for MPA and 6 for MA). The levels of 5-HT in culture supernatants of PBMC stimulated with CDDP were higher than controls (100 nM vs 51 for MPA study and 123 vs 64 for MA study) and were in the same range of PHA-stimulated PBMC.

Cisplatin induces serotonin release from human peripheral blood mononuclear cells of cancer patients and methylprednisolone inhibits this effect.

The aim of this study was to verify whether cisplatin (CDDP) can induce serotonin (5HT) release from peripheral blood mononuclear cells (PBMC) of cancer patients and determine whether methylprednisolone (MP) can inhibit such release. Ten patients (mean age 61.8 years) with cancer of different sites, all but one in advanced stage of disease were studied.

Tumor-associated lympho-monocytes from neoplastic effusions are immunologically defective in comparison with patient autologous PBMCs but are capable of releasing high amounts of various cytokines.

We studied several in vitro activities of tumor-associated lympho-monocytes (TALMs) and the concentrations of interleukin (IL)-1alpha, IL-1beta, IL-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF)alpha, interferon (IFN)gamma and soluble IL-2 receptor (slL-2R) in neoplastic effusions and in the serum of advanced stage cancer patients. Comparisons were made with autologous peripheral blood mononuclear cells (PBMCs). Autologous PBMCs were compared with PBMCs from normal subjects used as controls.
