[Characterization of tumor infiltrating lymphocytes from patients with renal cell carcinoma--influence of combination therapy with interferon alpha and gamma].

Background: In an attempt to define the effects of combination therapy with interferon alpha and gamma, lymphocyte subsets in tumor site and peripheral blood have been studied.

Methods: Tumor Infiltrating Lymphocytes (TILs) and Peripheral Blood Lymphocytes (PBLs) from 13 interferon-treated and 11 untreated patients with primary renal cell carcinoma were characterized by two color flowcytometry. Interferon-treated patients received interferon alpha and interferon gamma before radical nephrectomy; Interferon alpha was administrated intramuscularly at a dose of 3 x 10(6) units every other day from a week before nephrectomy.

[Diagnostic imaging of invasive renal pelvic cancer].

In 5 patients with invasive renal pelvic cancer, we evaluated the imaging features of drip infusion pyelography (DIP), retrograde pyelography (RP), ultrasonography (USG), computerized tomography (CT), magnetic resonance imaging (MRI) and renal angiography (RAG). The different features of high diagnostic value were as follows. DIP revealed no visualization with enlargement and reniform outline.

[Clinical evaluation of the long-term treatment with chlormadinone acetate in patients with benign prostatic hypertrophy].

Fifty patients with benign prostatic hypertrophy were treated with chlormadinone acetate (CMA) at the dose of 50 mg/day for 12 months. Subjective symptoms and objective findings were evaluated before, and after 4 and 12 months of treatment. Better improvement was observed in all of the subjective symptoms and in almost all the parameters of objective findings, in proportion to the period of CMA treatment.
