Computer identification of neoplastic urothelial nuclei from the bladder.

Objective: To introduce computer-based analysis of Feulgen-stained urinary bladder cell nuclei from voided urine to identify neoplastic urothelial nuclei.

Study Design: Nuclei from 23 healthy people and 33 patients with urinary bladder cancer were analyzed. The nuclei from 9 cancer patients with grade G1 (stage Ta), 17 with grade G2 (stages Ta, T1, T1a and T2) and 7 with grade G3 (stages Cis, Ta + Tis, T1 and T3b) were analyzed.

Collecting (Bellini) duct carcinoma of the kidney--clinical, radiologic and immunohistochemical findings.

We present clinical and radiological findings in a case of collecting (Bellini) duct carcinoma (CDC). This is a rare and aggressive kidney cancer originating from the distal renal tubule. The patient underwent radical nephrectomy and the pathological report showed trabeculopapillary, partially solid adenocarcinoma infiltrating the renal capsule and sinus.

[Preliminary clinical evaluation of systemic chemotherapy of invasive cancer of the bladder by the CMV protocol].

The authors discuss the results of preliminary clinical trials with chemotherapy with CMV (cisplatin, methotrexate, vinblastine) in the group of 17 patients with the infiltrating cancer of the bladder. Chemotherapy was used as an element of the radical treatment (in 7 patients, i.e.
