Current management of stage I testicular germ cell tumors in a French cancer institute. A practice analysis over the 10 past years.

BACKGROUND: Testicular Germ Cell Tumors (TGCTs) represent the most frequent malignant tumour among young male adults. Orchiectomy alone cure 80% of stage I. Standard options after orchiectomy include radiotherapy (RT), chemotherapy (CT) by 1 cycle of carboplatin AUC 7 or active surveillance (SV) for seminomatous GCTs (SGCT) and retroperitoneal lymphadenectomy (RPLND), CT by 1 or 2 cycles of Bleomycine Etoposide Cisplatine (BEP) or active surveillance for nonseminomatous GCTs (NSGCT). Adjuvant treatments decrease the relapse rate after orchiectomy with substantial toxicities without any benefit on overall survival. Recent guidelines accorded utmost importance on SV rather than adjuvants strategies. The main objective of this study was to describe our current practice over the 10 past years in regard of these recommendations. METHODS: Data of 50 patients with stage I GCT treated in our institute were collected between 2006 and 2016. Demographic and anatomopathologic data were reported. Clinical practice in our center was analyzed during two periods [2006-2011] and [2012-2016] according to the European Association of Urology Guidelines in 2011. RESULTS: Patient's median age was 35.3 years. The analysis of clinical practice during the last 10 years showed that in SGCT, main treatment was RT than SV and CT. This option declined over the years (89% between 2006-2010 versus 53% between 2011-2016) whereas SV was more often employed (27% between 2011-2016 versus none between 2006-2010). Surveillance was used for 64% of NSGCT. CONCLUSIONS: In our center, RT was less used over the years for the benefit of SV which is recommended by guidelines.

[Laparoscopic treatment of an isolated ureteropelvic junction disruption following blunt abdominal trauma]. / Traitement d'une rupture traumatique isolée de la jonction pyélo-urétérale par laparoscopie rétro-péritoneale.

Isolated disruption of the ureteropelvic junction following blunt abdominal trauma is rare, although not exceptional. The diagnosis may be delayed. CT-scan with excretory phase imaging is the usual mode of diagnosis. The urinary tract can be repaired by an ureteropyelic anastomosis over a stent. The authors report the first case of an isolated disruption of the ureteropelvic junction following blunt abdominal trauma repaired by retroperitoneal laparoscopy.

[One-stage laparoscopic bilateral upper pole nephrectomy for ectopic insertion of complete ureteral duplication]. / Néphrectomie polaire supérieure laparoscopique bilatérale en un temps pour abouchement ectopique d'une duplicité urétérale complète.

Ectopic ureteric insertion of the superior renal unit in the context of complete ureteric duplication is frequently accompanied by destruction of the corresponding parenchymal territory. Surgical treatment must comprise upper pole nephrectomy with partial ureterectomy. The authors report a case of one-stage retroperitoneal laparoscopic bilateral treatment which could become the treatment of choice of this disease.

[Prognostic factors of invasive bladder cancer with lymph node invasion]. / Facteurs pronostiques des cancers infiltrants de vessie avec envahissement lymphonodal.

OBJECTIVE: To identify the prognostic factors influencing survival and to assess the value of extensive lymphadenectomy in invasive bladder cancer with lymph node invasion. MATERIAL AND METHODS: The medical records of 62 patients treated by cystectomy with curative lymphadenectomy for invasive bladder cancer with lymph node invasion were reviewed. Thirty four patients had lymph node dissection ascending at least as far as the common iliac vessels, 26 had pelvic lymph node dissection and 2 had simple lymph node biopsies. RESULTS: The 2-, 3- and 5-year actuarial survival rates were 37%, 26.6% and 23.6%, respectively, with a median survival of 18.4 months. This study appears to show the independent prognostic value of the following factors: tumour strictly confined to the bladder (< or = pT3a) (p = 0.002), < or = 2 invaded lymph nodes (p = 0.001), N1 lymph node stage (p = 0.009). Extensive lymphadenectomy would not provide any benefit in terms of survival compared to simple pelvic lymph node dissection (p = 0.8). Common iliac node invasion appears to be a factor of poor prognosis when the tumour extends beyond the bladder (> pT3a) (p = 0.018). CONCLUSION: In these patients with invasive bladder cancer and lymph node invasion, a number of invaded lymph nodes < or = 2 and local stage < or = pT3a appear to be favourable prognostic factors resulting in a 23.6% remission rate (56.8% when both factors were present simultaneously) after cystectomy plus lymphadenectomy. Extensive lymphadenectomy including the common iliac vessels would not improve survival compared to pelvic lymph node dissection, but nevertheless appears us to be justified, as the presence of common iliac lymph node invasion constitutes a significant and powerful prognostic factor to recommend adjuvant therapy.
