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.

PURPOSEnA large hernia after flank incision for nephrectomy is a challenging problem in hernia surgery. In recent decades preperitoneal prosthetic herniorrhaphy became a widely accepted procedure for hernias of the abdominal wall. To evaluate the outcome of mesh hernia repair of the flank we reviewed our data on all patients who underwent preperitoneal mesh repair.nnnMATERIALS AND METHODSnWe identified 4 patients who underwent prosthesis repair after incisional hernia of the flank within the last 6 years. The primary reason for surgery was nephrectomy in 2 cases, pyeloplasty in 1 and complicated kidney cyst resection in 1. Mean followup time was 33 months.nnnRESULTSnIn a mean operative time +/- SD of 208 +/- 55 minutes the patients underwent incisional hernia repair with prosthesis implantation in the sublay position. In 3 patients an expanded polytetrafluoroethylene patch was used and in 1 polypropylene mesh was implanted. Mean prosthesis size was 25 x 38 cm. (950 +/- 300 cm. ). There were no postoperative complications. Patients were discharged from the hospital after a mean of 15 +/- 2 days. Followup revealed that none of the 4 patients with flank incision had recurrent hernia. Pain persisted in 3 patients after flank incision. However, no regular analgesic drug prescription was necessary.nnnCONCLUSIONSnMesh repair for incisional flank hernia provides reinforcement of the hernia. However, the flank remains paralyzed with a muscle bulge and some patients have persistent discomfort.

Objective: In patients with advanced metastatic renal cell carcinoma (RCC) seen at a single institution, the toxicity and long-term clinical effects of a combination therapy with recombinant interleukin-2 (rIL-2), recombinant interferon-α2 (rIFN-α2) and 5-fluorouracil (5-FU) were evaluated. Method: From August 1992 through August 1997, 47 consecutive patients (38 men) with metastatic RCC were treated using rIL-2 and rIFN-α2 subcutaneously in combination with intravenous 5-FU. An average of 2.4 cycles/patient (range 1–9) was administered. Results: Toxicity grades II and III (World Health Organization) were observed in 24 and 17 patients, respectively. We achieved 9 major responses (7 complete responses (CR) and 2 partial responses (PR)) for an objective response rate of 19.1% (95% confidence interval 9.1–33.3%). A further 13 patients (27.7%) had a stabilization of disease. After a mean follow-up of 17.9 (2–53) months, 4 patients are alive with no evidence of disease. The 1- and 3-year survival probability was 70 and 37%, respectively. In an univariate analysis, two prognostic factors were correlated with disease outcome: Karnofsky performance index (p = 0.01) and the presence of bone metastases (p = 0.023). Conclusion: This triple-drug combination therapy was effective in the treatment of progressive RCC in almost every fifth patient.

Adrenal cysts are rare disorders with an incidence in sev- eral autopsy studies of 0.064 to 0.18%. However, true epi- thelial cysts of the adrenal gland occur much more seldom and their existence is still doubted by some investigators.2 We report a case of a true epithelial-lined adrenal gland cyst, and discuss the possible pathogenesis, differential diagnosis and therapy of this lesion.

Der Zusammenhang zwischen Prostatavolumen und Prostatakarzinomdetektion wurde in einem Patientenkollektiv, das sich einer MRT-gestützten In-bore-Prostatabiopsie unterzog, untersucht. Zwischen Juni 2011 und Dezember 2015 wurden 140 konsekutive MRT-gestützte In-bore-Prostatabiopsien vorgenommen. Die klinischen Daten aller Patienten wurden prospektiv in einer Datenbank erfasst. Die präinterventionell mittels transrektalem Ultraschall (TRUS) ermittelten Prostatavolumen wurde in Gruppen (Gr) unterteilt: Gr A: <25u2009ccm; Gr B: 25–50u2009ccm; Gr C: 50–75u2009ccm; Gr D: 75–100u2009ccm; Gr E > 100u2009ccm. Die statistische Auswertung wurde mit IBM® SPSS® Statistics v.20.0.0 vorgenommen. Das mittlere Alter war 66,7 (47–81) Jahre. Im Median waren im Vorfeld 2 (0–6) Prostatabiopsien erfolgt. Der mittlere PSA-Wert betrug 9,6 (0,8–30,6)u2009ng/ml. Das mittlere Prostatavolumen wurde mit 40,9 (6–121) ccmu2009angegeben. Die Gesamtdetektionsrate war 48,6u2009% (68/140). Die PCa-Detektionsrate war 60u2009% in Gr A (18/30), 62u2009% in Gr B (44/71), 16,7u2009% in Gr C (5/30), 12,5u2009% in Gr D (1/8) und 0u2009% in Gr E (0/1). Die Unterschiede waren statistisch signifikant (p < 0,001). 5/6 der detektierten PCa bei einem Prostatavolumen >50u2009ccm zeigten einen Gleason 3 + 3 = 6, 1/6 einen Gleason 3 + 4 = 7a. Das Prostatavolumen war in dieser Patientenserie ein unabhängiger prädiktiver Faktor für PCa-positive Biopsieergebnisse. Bei Prostatae >50u2009ccm war die Detektionsrate signifikant geringer. Die in Prostatae >50u2009ccm detektierten PCa waren überwiegend Low-grade-Tumoren. Diese Erkenntnisse sollten für differenzialdiagnostische Überlegungen bei großen Prostatae – insbesondere nach vorangegangener negativer Biopsie – berücksichtigt werden.
