The purpose of this study was to evaluate in a randomized phase II trial the efficacy and toxicity of combination biochemotherapy compared with chemotherapy alone in patients with metastatic melanoma. Sixty-five patients with metastatic melanoma (ECOG performance status 0 or 1) were randomized to receive intravenous BCNU 100 mg m(-2) (day 1, alternate courses), cisplatin 25 mg m(-2) (days 1-3), DTIC 220 mg m(-2) (days 1-3) and oral tamoxifen 40 mg (BCDT regimen) with (n = 35) or without (n = 30) subcutaneous interleukin 2 (IL-2) 18 x 10(6) iu t.d.

However, non-responders still account for up to 80% of those patients receiving IL-2. A high concentration of soluble IL-2 receptor (sIL-2R) is commonly found in the blood of such patients.

Twelve patients were treated with a range of doses of IL-2 (3 x 10(3) to 3 x 10(6) international units/day) by continuous intra-arterial infusion for 10 days. Biopsies of the tumour were taken pre- and 48 h post-therapy, snap-frozen, cut, and examined histologically and immunocytochemically.

Patients And Methods: Five patients with RCC were monitored before and over a period of up to 3 months after nephrectomy. The aspects measured were the phenotypic expression of markers on circulating lymphocytes, circulating concentrations of cytokines, markers of inflammatory and immune responses, and natural killer (NK) cell and lymphokine-activated killer (LAK) cell activity in peripheral blood mononuclear cells (PBMC).
Interleukin-2 (IL-2) was administered locally by constant intra-arterial infusion in four escalating doses from 3 x 10(4)-3 x 10(7) IU/day to 12 patients with squamous cell carcinoma of the head and neck (SCCHN) in a phase I trial. Lymphocyte phenotypic markers and serum cytokine concentrations were measured over the course of treatment. Serum IL-1-alpha, -beta and IL-6 were not induced at any dose level.

Plasma neopterin concentrations are increased in people with bacterial septicemias, viral infections, and graft vs host disease. Plasma concentrations of CRP and neopterin were measured daily in 21 bone-marrow transplant (BMT) patients, 64 patients in intensive-care units (ICU), and 12 patients with squamous cell carcinoma of the head and neck (HN).
View Article and Find Full Text PDFA novel staining method for simultaneously determining the immunophenotype and sex of peripheral lymphocytes is described. Cell surface markers on lymphocytes are identified using specific monoclonal antibodies located by a peroxidase anti-peroxidase staining technique (PAP). Lymphocytes are subsequently hybridised with a biotinylated Y chromosome-specific sequence probe and this is located by avidin-biotin-alkaline phosphatase staining.
