Prostate atypia: clinical and pathological variables associated with cancer diagnosis on repeat biopsy.

The clinical significance of atypical glands suspicious for malignancy (atypia) on prostate biopsy is unclear. We studied a cohort of 139 patients with atypia who underwent repeat prostate biopsy. We analyzed clinical and pathological variables that may be associated with cancer on repeat biopsy. Cancer was diagnosed in 41 (29%) of patients with atypia: 26 of 41 (66%) were Gleason 6, 20% were Gleason 7 and 7% were Gleason 8 (Gleason < 6 not reported). There were no significant associations of age, race, family history, PSA, PSA density (PSAd), number of previous biopsies or time to repeat biopsy with cancer diagnosis. In multivariate regression, histological inflammation was associated with an 85% decreased probability of cancer on repeat biopsy (odds ratio; OR 0.15; 95% confidence interval; CI 0.04-0.57; P=0.04). Radical prostatectomy was performed in 14 of 41 (34%) patients with cancer; 6 (43%) were Gleason sum ≥7, 3 (21%) were pT3a and 1 (7%) had lymph node metastases. In conclusion, inflammation was independently associated with a significantly decreased risk of cancer on repeat biopsy. However, some patients with initial atypia have higher-risk prostate cancer. Additional studies are needed to elucidate these associations.

Laparoscopic and percutaneous cryotherapy for renal neoplasms.

Incidence of renal cell carcinoma is increasing. There has been a shift towards utilization of nephron sparing surgery when feasible. Minimally invasive ablative treatments such as laparoscopic and percutaneous renal cryoablation aim to treat renal tumors with the two goals of cancer eradication and reduced morbidity compared to excisional surgical approaches. In this article, we review the basis of cryobiology and examine the current role of renal cryoablation and analyze the current literature focusing on laparoscopic and percutaneous approaches and discuss future directions and refinements in cryosurgical technology. While renal cryoablation is associated with higher local retreatment rates compared to radical or partial nephrectomy, emerging reports of intermediate-term oncological outcomes suggest disease-specific survival approaching that of extirpative surgery. Further follow up is needed to elucidate the long-term oncologic outcomes of and effects on renal function by renal cryoablation.

[Subtotal demolition of the uterus and subsequent pregnancy (author's transl)]. / Subtotaler Uterusabriss mit nachfolgender Schwangerschaft.

This is a case report on a severe injury to the female genital organ with subtotal rupture of the uterus caused by rape. The surgical approach taken to the case is discussed together with problems relating to more recent pregnancy. Caesarean section was the primary approach taken in the knowledge of excessive destruction of the uterine ligaments. Birth was given to an intact infant.
