Prospective Outcome Analysis of the Safety and Efficacy of Partial and Complete Cryoablation in Organ-confined Prostate Cancer.

OBJECTIVE: To determine the rate of complications and change in International Prostate Symptom Score and Sexual Health Inventory for Men scores following cryotherapy treatment of low- and intermediate-risk prostate cancer. The secondary end points were the change in prostate-specific antigen post cryotherapy and biopsy-proven recurrence. MATERIALS AND METHODS: Enrollment occurred from 2007 to 2015 to assess long-term complications of cryotherapy. A prostate biopsy was performed at 1 year or in the event of biochemical failure. Subjects were staged and graded by standard 12- to 14-core transrectal ultrasound (TRUS) biopsy. A subset of subjects underwent additional 3-dimensional mapping biopsy if the cancer was suspected to be downgraded. Analyses of functional outcomes were stratified into focal and nonfocal treatments. RESULTS: The study consisted of 393 men with low- and intermediate-risk prostate cancer, aged 44-89 years. Patient IPSS scores improved significantly in the nonfocal treatment strata at all time points and after 1 year in the focal strata with a median drop at 1 year of 4 points (P <.001). No significant difference was detected for a change in preprocedural SHIM score in either treatment strata after 2 years (P >.7). Eighty-two patients (20.9%) had a rise in prostate-specific antigen resulting in biochemical failure. Seventy patients had detected recurrence for an overall recurrence rate of 20.4% in 343 patients. A total of 109 patients (27.7%) reported urinary retention and urgency post cryotherapy, with 15.3% requiring catheterization for up to 3 weeks. Thirty-seven patients (9.4%) experienced urethral meatal stricture, and 36 patients (9.2%) reported unresolved new-onset erectile dysfunction. CONCLUSION: Complication rates, most significantly erectile dysfunction, are decreased in this study compared with those previously reported in the literature for cryotherapy for prostate cancer.

An unexpected finding of hepatic lymphoma after emergent cholecystectomy.

Herein we describe a case report of a patient with elevated liver enzymes, leukocytosis, anemia and fevers after cholecystectomy surgery done for presumed acute cholecystitis. Numerous post-surgical tests showed no acute surgical complications to account for the laboratory abnormalities. Due to systemic symptoms of joint pain and the chronicity of the symptoms, a liver biopsy was recommended by the gastroenterology service to rule out infectious or auto-immune causes. After the liver biopsy, the patient was diagnosed with intravascular large B-cell lymphoma (IVLBCL), a subset of diffuse large B-cell lymphoma. After a thorough lymphoma evaluation, the IVLBCL was found to be isolated to the liver and treated successfully with chemotherapy. This is only the second case report in the literature of this entity.
