From 1967 to 1985 conservative surgery (enucleation, n = 49; partial resection, n = 7) was performed for renal tumors in 57 patients (age 31-77, mean 54.8 years). Imperative indications for conservative surgery (n = 29) were chronic renal failure, benign pathology of contralateral kidney, functional or anatomical solitary kidney, and bilateral tumors. Elective conservative surgery (n = 28) was done for small, peripherally located lesions, in cases of uncertain malignancy and in one tumor detected by chance during stone surgery. Tumors removed for imperative indications were 2-11 cm (mean 5.8 cm) in size. In the elective group, tumor size ranged from 1 to 7 cm (mean 3.3 cm). Follow-up was 6-103 months (mean 35.8 months). In the group with imperative indications, there was 1 postoperative mortality; 18 of 29 patients are alive without evidence of disease, 2 with metastases, and 2 were reoperated conservatively for local recurrences; 1 was lost to follow-up, 2 died of metastases, and 3 died due to unrelated reasons. In the elective group all 28 patients are living free of cancer.

Four patients in terminal renal failure who had various malignant tumours were treated by haemodialysis and cadaveric renal transplantation. One patient with a testicular seminoma and one with leiomyosarcomatous changes in polycystic kidneys were successfully grafted after removal of the tumours and both were healthy at three and two-and-a-half years afterwards without evidence of recurrence of tumour.One patient with an invasive carcinoma of the renal pelvis was successfully transplanted and remained well for eight months but rapidly deteriorated and died of extensive metastases. Another patient with a malignant melanoma died more than one year after unsuccessful grafting.The presence of concomitant malignant disease in patients with chronic renal failure need not necessarily exclude them from the chance of long-term treatment, including renal transplantation. Each patient should be considered individually from the point of view of the nature of the malignancy, its duration, and treatment.

Forty-two patients with advanced testis carcinoma without previous chemotherapy were treated with VAB-4, and 41 were evaluable. The program consisted of three in-hospital inductions 16 weeks apart, and outpatient treatments every three weeks. Of the patients, 80% achieved complete remissions (CR). Chemotherapy alone induced CR in 61%, partial remissions (PR), in 24% and minor response (MR), in 15%. An additional 20% of patients (six PRs and 2 MRs) achieved CR following resection of residual tumor deposits. With a median follow-up of 27 months, the median duration of CR has not been reached. Of those achieving CR to chemotherapy alone, 12% had relapses. Bulk and extent of metastatic disease, histology of primary tumor, and tumor markers at the beginning of therapy influenced the frequency of CR. Of those with minimal disease, 90% achieved CR. The CR rate was 67% for those with advanced thoracic disease and 29% for those with advanced abdominal disease. Patients who had embryonal carcinoma and those who had no elevation of alpha-fetoprotein had a higher frequency of CRs. Myelosuppression with a leukocyte count drop less than 1000/mm3 occurred in three patients, and no patient had chronic renal failure or pulmonary fibrosis. One patient died from sepsis while in complete remission.

In view of the characteristic intra-abdominal spread of carcinoma of the colon and rectum [1-3], the use of intraperitoneal chemotherapy may offer an alternative to intravenous or oral drug therapy and even radiation therapy for recurrent disease [4,5]. Several investigators have demonstrated that intraperitoneal drug administration may result in portal vein levels ten to 20 times higher than those observed in peripheral venous blood samples [6]. Traditionally, intraperitoneal chemotherapy has been administered through the Tenckhoff catheter system which was originally developed for peritoneal dialysis in patients with acute or chronic renal failure [7,8]. We report a case of Tenckhoff catheter erosion into the colon with subsequent fistulization developing 20 days after intra-operative placement for intraperitoneal or "belly bath" chemotherapy; this complication occurred in a patient with locally recurrent colorectal adenocarcinoma in whom pelvic peritoneal implants without hepatic metastases were identified at reoperation. This complication of the Tenckhoff catheter system has not previously been reported in the surgical literature.

A 67-year-old woman died after 4 years of treatment by haemodialysis. End-stage renal failure was caused by polycystic kidney disease. Malignancy was suspected in the last 6 months of treatment because of impressive weight loss and a suspect liver-scan. Macroscopic haematuria in the first period of treatment was noted only once. Necropsy revealed renal carcinoma of the right polycystic kidney and tumour metastases in various organs. The problem of development of renal carcinoma in polycystic kidney disease in the light of the increased incidence of malignancy during chronic renal failure is discussed.

Cross-sectional echocardiography was performed on 69 patients with pericardial effusion. The etiology of the pericardial effusion was malignant infiltration of the pericardium in nine patients; chronic renal failure in 10; postcardiac surgery in 31; viral pericarditis in three; tuberculous pericarditis in two; and undetermined in 14. Seven of the nine patients with pericardial metastases were noted to have irregular cauliflower-like masses protruding from the pericardium and the epicardium into the echo-free space of the pericardial effusion. These masses demonstrated a to-and-fro motion within the pericardial space during ventricular systole. The presence of pericardial metastases was confirmed at operation in four cases and the three others had intrathoracic or colonic malignancy with widespread metastases. None of the patients without pericardial metastasis showed the characteristic abnormality seen in patients with pericardial metastases. Six patients had dense linear echoes connecting the pericardium and epicardium that probably represented adhesions (confirmation at surgery in one, and confirmation at autopsy in another), with an appearance that was different from that seen in pericardial metastases. We conclude that cross-sectional echocardiography may be useful for detecting pericardial metastases.

A 15-year old male with chronic renal failure secondary to obstructive uropathy received an adult cadaveric donor kidney. Evaluation for painless macroscopic hematuria occurring 2 years after transplantation disclosed a metastatic renal cell carcinoma, which by the use of restriction fragment length polymorphism analysis was shown to be of the donor's origin. Transplant nephrectomy and cessation of immunosuppressive therapy resulted in complete regression of multiple pulmonary metastases.

A total of 65 patients with von Hippel-Lindau disease underwent surgery for renal cell carcinoma (54 bilaterally and 11 unilaterally) at 8 medical centers. Only 1 patient presented with metastatic disease. Radical nephrectomy and nephron sparing surgery were performed in 16 and 49 patients, respectively. Mean posttreatment followup was 68 months. The 5 and 10-year cancer-specific survival rates for all patients were 95% and 77%, respectively. The corresponding rates for patients treated with nephron sparing surgery were 100% and 81%, respectively. Of the latter patients 25 (51%) had postoperative local tumor recurrence but only 2 had concomitant metastatic disease. Survival free of local recurrence was 71% at 5 years but only 15% at 10 years. End stage renal failure occurred in 15 patients (23%): 6 underwent renal transplantation (5 are alive with satisfactory renal function and no evidence of malignancy) and 9 were treated with chronic dialysis (6 are free of tumor). Our results indicate that nephron sparing surgery can provide effective initial treatment for patients with renal cell carcinoma and von Hippel-Lindau disease. These patients must be followed closely, since most will eventually have locally recurrent renal cell carcinoma. When removal of all renal tissue is necessary to achieve control of malignancy, renal transplantation can provide satisfactory replacement therapy for end stage renal disease.

From 1985 to 1991 the author operated on 21 bladder cancers, forming cross anastomoses on the upper urinary tracts. 19 patients underwent cystectomy. Stage T2, T3, T4 was diagnosed in 4.8%, 80.9% and 14.3% of the patients, respectively. Hydroureteronephrosis was detected in all the patients, chronic pyelonephritis developed in 16 (76.2%), chronic renal failure in 9 (42.9%). Upper and low transureteroureteronephrostomy (TUUN) was performed in 13 (61.9%), transureteropyelonephrostomy (TUPN) in 3 (14.3%), transureteropyelo-ureterosigmoidostomy in 5 (23.8%) patients. The latter technique implies successive connection of the kidneys with the sigmoid. This provided less exposure of one of the kidneys to the intestinal infection, urinary fistulas did not form. Two deaths in the postoperative period were due to metastases and thromboembolism. The authors believe that the best functional conditions for the kidneys are secured by upper TUUN, TUPN and transureteropyelo-ureterosigmoidostomy applicable in cystectomy and in normal tonicity of the upper urinary tracts.

Glomus tumors are characteristically benign solitary tumors. A few cases of malignant glomus tumors have been reported; however, they are usually only locally invasive, and metastases are exceedingly rare. We report a case of widespread metastases of a malignant glomus tumor involving the skin, lungs, jejunum, liver, spleen, and lymph nodes in a 63-year-old man with end-stage chronic renal failure. At autopsy, multiple glomus body hamartomas were also noted throughout the dermis proximal to the skin tumors. Histologically, the tumor was composed of monotonous round cells in solid sheets and investing numerous capillary-sized vessels. Approximately four to six mitoses were present per high-power field. The tumor cells were strongly immunoreactive for actin and vimentin, and ultrastructurally there were whorls of microfilaments with focal condensations. This case is exceptional because of its aggressive course.
