Correlation between tissular levels of prostatic acid phosphatase and prostate-specific antigen and hormonal response of metastatic prostatic cancer.

A correlation between the serum levels of testosterone and the tissular intensity of prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) in normal prostates has been demonstrated. In prostatic cancer patients, we studied the correlation between the percentage of neoplastic cells secreting PAP and PSA and the response to androgen deprivation, and found no relationship between them. Therefore it is not possible to predict the response to hormone therapy through the grade of tissular PAP or PSA.

Fiberendoscopy in the diagnosis of the pathology of the ileal conduit.

The advantages of the exploration with flexible fiberendoscopy in the pathologies of the ileal conduit, as in hematuria, are commented. The method to be followed, as well as the results of the explorations in 2 patients are evaluated. This method has proved to be highly advantageous compared with the standard methods.

Nuclear magnetic resonance in advanced prostate cancer (stage D).

Nuclear Magnetic Resonance (NMR), a recently developed diagnostic method, has proved to be useful in the study of patients with prostatic disease. The authors report their experience with this technique in 10 cases of advanced prostate cancer (stage D) treated with LH-RH agonists (HOE 766-Buserelin). NMR provided information on the size of the prostate, the invasion of the vesical floor and seminal vesicles and the involvement of the pelvic and retroperitoneal nodes. It was also useful for ruling out metastases in the pelvis and spinal column, and showed an excellent correlation with the bone scan. In 2 untreated cases, NMR was sufficient by itself to diagnose metastatic prostate cancer. However, given the current lack of experience, it is not yet possible to draw conclusions concerning the superiority of this technique over other methods in the diagnosis and staging of prostatic carcinoma.

[Preventive chemotherapy of superficial tumors of the bladder].

A retrospective study of 135 patients with superficial transitional cancer of bladder (pTa - pT1) was conducted after follow-up for at least 3 years following treatment for 2 years at the "Instituto de Urología, Nefrología y Andrología (Fundación Puigvert)". Patients had been randomly allocated for treatment with: RTU alone, RTU + instillation of Thiotepa and RTU followed by instillations of Adriamycin. Chemotherapy was administered preventively. Recurrence after 3 years and possible progression towards infiltration during this period were evaluated, and the usefulness of this type of treatment questioned because of the cost/benefit ratio and small intergroup differences found.

[Isolated renal angiomyolipoma. Study of 10 cases].

The authors review 10 cases of isolated renal angiomyolipoma collected from the archives of the Institute of Urology, Nephrology and Andrology, Barcelona, Spain (Fundacion Puigvert) which contain a total of 170,000 records collected between 1930 and 1980. They describe the clinical, laboratory, histopathological and therapeutic characteristics, as well as the course of the cases studied in comparison with parenchymatous renal tumours, angiomyolipomas accounting for 2.07%. The attention of the reader is drawn to the fact that all the cases presented here were of isolated renal angiomyolipomatosis, in the absence of any context of phakomatosis and no possibility of preoperative diagnosis by conventional methods of investigation. It is felt that a preoperative diagnosis would be possible by computed tomography using the scanner by virtue of the adipose content of the angiomyolipoma.

Fibrous polyp of the ureter.

The most frequent ureteral tumors are transitional carcinoma. Benign neoplasms are uncommon. In this paper we present 6 cases of ureteral polyps, which represent 11.1% of all the tumors in our series of ureteral tumors. We have reviewed the possible etiopathogenesis and exposed the clinical characteristics. Secondary to the obstructive phenomenon and the radiologic signs, it is the tigroid appearance, the localization and the absence of total obstruction which allows the diagnostic suspicion. The treatment of choice is partial resection. Ureterostomy with peroperatory biopsy, in cases in which the malignancy is not yet established, is recommended in order to avoid unnecessary nephroureterectomies.

[Adenocarcinoma in bladder. Apropos of a case].

Finding an adenocarcinoma at the vesicle suggests three possible diagnosis: Intestinal adenocarcinoma with vesical location. Adenocarcinoma of the urachus. Vesical primitive adenocarcinoma. Presentation of one case of intestinal adenocarcinoma, revealed by its mictional symptomatology, with the endoscopic appearance of being a single vesical tumour, later shown to be a vesical adenocarcinoma, on which extended surgery of the gut and partial surgery of the bladder was performed.

[Value of LDH in the diagnosis of pseudocystic renal cancer].

An asymptomatic case of cystic renal carcinoma is presented. The only diagnosis of certainty was given by a marked increase in L.D.H. levels in the fluid of the tumor after puncture. The pros and cons of imaging studies, and the relative lack of value of aspiration cytology when negative results are encountered are discussed. The pathological anatomical findings of the nephrectomy sample certified the diagnosis, showing the presence of a pseudocystic adenocarcinoma due to intratumor necrosis.
