Histopathological findings after radiofrequency (RITA) treatment for prostate cancer.

Radiofrequency interstitial tumor ablation (RITA) is a thermal ablation method that uses needles and low radiofrequency (RF) energy. The aim of our study was to evaluate the histopathology of thermal lesions induced by RF energy delivered interstitially in prostate cancer patients who subsequently underwent prostatectomy, and to determine the feasibility, effectiveness and safety of this new method in a pilot study.

[Comparison of orthotopic neobladders: Studer vs modified Camey II].

A comparative study between modified Camey II and Studer ileal orthotopic neobladder was performed. The Camey II was modified as follows: 1) The ureters were implanted, using wallace technique, in an undetubularized ileal loop, 15-18 cm. long, to prevent vesico-ureteral reflux; 2) The neobladder was made using staplers.

[Neoadjuvant chemotherapy with MVC (methotrexate, vinblastine, cisplatin)in the treatment of infiltrating transitional carcinoma of the bladder].

Of 19 patients with advanced transitional bladder cancer (T2-T4, N0-N+, M0) who received two or three cycles of pre-emptive MVC (Methotrexate, Vinblastine, Cisplatin), pathological partial (PR) and complete (CR) remissions were observed in 67% (50% and 17% respectively). The toxicity of chemotherapy was generally acceptable but 5 patients required hospitalization for neutropenia and thrombopenia . In one of them chemotherapy was stopped for severe sepsis.

The role of partial cystectomy in the management of transitional bladder cancer.

A study on 81 patients who underwent partial cystectomy for bladder cancer is presented. The low postoperative mortality (2.46%) and the high 5-year survival (72%) show that this type of surgery is effective and without major complications.

Renal cell carcinoma and transitional cell carcinomas of the pelvis and bladder in a patient affected by chronic renal failure due to abuse of phenacetin.

This is a report on a case of 2 concurrent neoplasms of different histology within the same kidney: a renal cell carcinoma and a transitional cell carcinoma of the renal pelvis in a patient affected by chronic renal failure due to abuse of phenacetin. There was also a transitional cell carcinoma of the urinary bladder.
