Efficacy of HIVEC in patients with high-risk non-muscle invasive bladder cancer who are contraindicated to BCG and in patients who fail BCG therapy.

PURPOSE: To evaluate Hyperthermic-Intra-Vesical Chemotherapy (HIVEC) efficacy regarding 1-year disease-free survival (RFS) rate and bladder preservation rate in patients with High-risk Non-Muscle Invasive Bladder Cancer (NMIBC) who fail BCG therapy or are contraindicated to BCG. METHODS: Between June 2016 and October 2019, patients treated with HIVEC for mostly high-risk NMIBC who failed BCG or BCG-naive if BCG contraindicated have been included in our study. These patients had a theoretical indication for cystectomy but were ineligible for surgery or refused it. RESULTS: Fifty-three patients, median age 72 [39-93] years, were included in this study (n = 29 BCG-failure and n = 24 BCG-naive). The median follow-up was 18 months. The bladder preservation rate was 92.4%. The 12 months-RFS rate was 60.5%. The RFS rates for BCG-naive and BCG-failure groups were respectively 70% and 52.2% at 12 months. Three patients progressed to muscle infiltration, all in the BCG-failure group and all in the very high-risk EORTC group. Two of them developed metastatic disease and died from bladder cancer. CONCLUSION: Chemohyperthermia using HIVEC achieved a RFS rate of 60% at 1 year and enabled a bladder preservation rate of 92%. Given the low risk of progression in the BCG-naive group, HIVEC could be a good alternative. Conversely, for patients with very high-risk tumors that fail BCG, cystectomy should remain the standard of care and HIVEC may be discussed cautiously for patients who are not eligible for surgery and well informed of the risk of progression to muscle-invasive disease.

Major response with sorafenib in advanced renal cell carcinoma after 14 years of follow-up.

Tyrosine kinase inhibitors have dramatically improved the prognosis of metastatic renal cell carcinoma (RCC). However, it remains unknown whether treatment should be continued until progression or discontinued in patients with good response. We present the history of a woman diagnosed with RCC in 1997, who started sorafenib in 2004, two years after the occurrence of lung and mediastinal metastases. Over the following 8 years, the sorafenib dose was reduced at least 3 times due to toxicity and the treatment was discontinued twice upon the patient's decision, from May 2005 to March 2009, then from January 2011 to August 2011. The last evaluation in January 2013 showed stable disease. This case illustrates the feasibility of treatment discontinuation without negative impact on survival, as previously shown by some authors.

Surgical anatomy of the prostate in the era of radical robotic prostatectomy.

PURPOSE OF REVIEW: New insights in the anatomy of the prostate and the surrounding tissue evolve the technique of radical prostatectomy for the treatment of prostate cancer. RECENT FINDINGS: Regarding the course of the erectile nerves along the prostate, recent studies confirmed the presence of parasympathetic pro-erectile nerve fibers at the anterolateral aspect of the prostate. Another study of intraoperative electrostimulation of those nerves confirmed an increase in intracavernosal pressure by stimulations between the 1 and 3 o'clock position. Therefore, it is very likely that these anterior nerve fibers have an effect on erectile function. Regarding the urethral sphincter in the male, a study showed no attachment of the external sphincter to the levator ani muscle, probably resulting in an absence of a levator ani support to the continence mechanism. The male urinary sphincter seems to be in isolation responsible for urinary continence. SUMMARY: The nerve fibers at the anterolateral aspect of the prostate seem to participate in erectile function, which renders the concept of a high anterior release during nerve sparing beneficial. The isolated urinary sphincter mechanism results in the need to conserve as much urethral length as possible during radical prostatectomy to avoid urinary incontinence.

Effect of autologous blood transfusion on the rate of biochemical recurrence after radical prostatectomy.

OBJECTIVE: To test the association between autologous blood transfusion (ABT) and biochemical recurrence (BCR) after radical prostatectomy (RP) in a large group of contemporary patients. PATIENTS AND METHODS: We analysed 1291 patients treated with RP; Kaplan-Meier analysis was used to graphically explore the association between ABT and BCR. Cox regression models addressed the association between ABT and BCR in univariate and multivariate analyses, after adjusting for preoperative prostate specific antigen level, pathological Gleason sum, extracapsular extension, seminal vesicle invasion and lymph node invasion. RESULTS: Of all patients, 205 (15.4%) received perioperative ABT. The mean (median, range) follow-up was 43.2 (40.9, 0.3-145) months. BCR was recorded in 347 (26.9%) patients and the time to BCR was 25.2 (20.5, 0.3-107) months. Neither in univariate (P = 0.053) nor in multivariate (P = 0.2) Cox regression analyses was ABT a statistically significant or independent predictor of BCR. CONCLUSION: Perioperative ABT does not predispose to a higher rate of BCR in patients after RP.
