[Preventive bilateral pulmonary irradiation in renal neoplasms].

The aim of the study was to evaluate the role of bilateral lung radiotherapy in the prevention of lung metastases from renal cell carcinoma. The preliminary results are presented. Between 1981-1984, 38 patients with renal cell carcinoma with no evident lung metastases and with normal respiratory function (confirmed by gas analysis, spirometry, diffusion test) were submitted to radical nephrectomy with regional lymphadenectomy. The patients were randomly assigned to two groups. 19 patients were treated with lung radiotherapy (1,500 rad in 5 times with overlap on the mediastinum--3,000 rad) two weeks after surgery, 19 patients did not undergo further treatment after surgery. Chest X-rays and functional lung evaluation were performed at 3.6 and 12 months, and then every six months. Results in the first group (lung radiotherapy) showed no cases of lung fibrosis; 15 patients are disease-free (follow-up: 3-36 months); 4 patients died from cancer, only 1 of whom with lung metastases. In the second group (no lung Radiotherapy) 14 patients are disease-free whilst 5 patients died with lung metastases.

Nonrefluxing colon conduits with a modified ureterocolonic anastomosis.

Urinary diversion by means of a colon conduit is particularly advantageous. In comparison with the ileal conduit an antireflux ureterocolonic anastomosis can be created, thus preventing renal damage in patients with a long life expectancy. Herein the authors present the results of 5 years experience with colon conduits and Pagano's ureterocolonic anastomosis.

[Treatment of bladder carcinoma in situ].

The authors report their experience in the treatment of 21 patients with carcinoma situ of the bladder. Although the safest therapy is radical cystectomy this operation nevertheless is extremely mutilating. For these reason initially we prefer local chemotherapy with ADM continued with careful follow-up of the patient.

[Locoregional staging of prostatic neoplasms by extemporaneous histological examination of pelvic lymph nodes].

Pelvic lymphadenectomy prior to radical prostatectomy is essential to detect lymph nodal extension of prostatic cancer. Accuracy obtained by means of frozen section examination of the nodes is particularly favourable. Frozen sections correspond to paraffin sections in 100% of the cases. Authors' experience in 42 consecutive patients candidates to radical prostatic procedure is herein presented.

Water-path echotomography in differential diagnosis of scrotal masses.

Experience with Octoson water-path echotomography in examining 21 testicular masses is reported. Sonographic results were confirmed by surgical and pathologic findings in all cases. We believe this procedure to be of value in differential diagnosis of intrascrotal swellings.

Five years of experience with a modified technique of ureterocolonic anastomosis.

The thick colonic wall permits the creation of an antirefluxing ureterocolonic anastomosis, which reduces the incidence of pyelonephritis and limits the deterioration of renal function. Since 1977 a simple procedure for ureterocolonic anastomosis performed entirely outside of the colon was used in 63 patients. Obstructive complications were encountered in 6.4 per cent, while ureterocolonic reflux occurred in 5.6 per cent of the renoureteral units. Acute pyelonephritis developed in 7 patients.

Transrectal thin-needle aspiration biopsy of prostate: four years' experience.

Fine-needle aspiration biopsy of the prostate is of great advantage in the diagnosis of prostatic disease. The procedure is quick, safe, and reliable. Several aspirations can be done even in outpatients with minimum trauma. Complications are rare. In this study cytologic diagnosis was obtained in 511 consecutive patients. To evaluate the cytologic accuracy, 195 cytologic diagnoses were compared with histologic findings obtained from transperineal biopsy on the same patients. Correlation was achieved in 96.42 per cent of these cases. The findings in 127 histologically graded prostatic cancers were compared with the cytologic differentiation observed in aspiration smears of the same patients. Cytologic grading of prostatic carcinoma corresponded to the histologic grading in 85.8 per cent of the cases.

Treatment of sequential bilateral germ cell tumors of the testis following interval retroperitoneal lymph node dissection.

Modification in lymphatic drainage following retroperitoneal lymph node dissection, such as a collateral circulation or lymph node and lymphatic vessel regeneration, was observed in 2 patients in whom a second tumor developed in the remaining testicle. Such alterations of the lymphatic system are difficult to evaluate for the possible presence of metastatic disease. The presence of extensive collateral circulation rules out lymph node dissection or radiation therapy as an appropriate treatment in these patients. A short course of systemic chemotherapy, regardless of the histological type of the second malignancy, seems to be the safest adjunctive treatment in such cases.

Estramustine phosphate (Estracyt) treatment of T3-T4 prostatic carcinoma.

From September, 1978, to November, 1980, 69 consecutive patients with locally advanced (T3-T4) prostatic adenocarcinoma, with or without distant metastases, were treated with oral estramustine phosphate. Dosage was 15 mg/kg/day for 2 months, followed by 5 mg/kg/day until progression. In the 48 evaluable patients with progressive disease that entry in the study, 1 complete response, 7 partial responses, 31 disease stabilizations, and 9 progressions were encountered (81.2% NPCP response rate). Karnofsky performance status equal to or less than 50 was predictive of poor response to estramustine phosphate. In the 10 evaluable patients with stabilized disease at entry in the study after orchiectomy, 2 complete responses, 4 partial responses, 3 disease stabilization, and 1 progression were noted. The major side effects observed were gynecomastia, nausea, and vomiting.

[Carcinoma of the penis: our current therapeutic attitude].

24 cases of penile carcinoma, occurred from 1970 to 1979, have been examinated. The role of limphoadenectomy, the treatment of the primitive lesions and their consequences are discussed. It is opinion of the authors that the risks and the benefits of the treatment must be carefully evalued.

[Treatment of renal carcinoma with metastases].

They stress the need to evaluate certain characteristic of the tumour metastasis in the light of a series of limit events pin-pointing the lack of understanding of the natural history of renal carcinoma. They stress the need to evaluate certain characteristic of the tumour which are not normally taken into consideration by the surgeon: rate of proliferation, monitoring of hormonal receptors, and immunological monitoring. They reach the conclusion that treatment of renal carcinoma with metastasis must be the outcome of multidisciplinary planning.
