Synergo at the EAU Annual Meeting 2014

EAU Annual Meeting, April 2014

Medical Enterprises thanks the urology colleagues, teams and organizers for the successful EAU congress in Stockholm this month. The congress was very successful and fruitful. Also many thanks for the new visitors who expressed their interest in the Synergo system.

2 poster sessions were presented at the EAU meeting this year by Mr. Issa and Mr. Nair from the UK. 

Challenging the gold standard: A comparison of long-term disease specific outcomes for high-risk non-muscle invasive bladder cancer treated with mitomycin hyperthermia and radical cystectomy:

A prospective single-centre review of 96 patients receiving Synergo MMC-HT and matched against 47 cases undergoing RC for High-Risk Non-Muscle Invasive Bladder Cancer. Charlson co-morbidity Index (CCI), and peri- and post-procedure complications were recorded in each group. Post operative pathology, recurrence and progression rates together with five-year overall and disease specific survival were evaluated.

The mean CCI score for patients receiving MMC-HT was significantly higher than RC group (6.1 vs 4.3). Significant complication rates classified as a Clavian-Dindo score of greater than 2, was significantly higher in the RC cohort (21 percent) compared to patients receiving MMC-HT (0 percent).

There were no deaths associated with MMC-HT treatment compared to a ninety-day mortality of four percent in those receiving RC.

Median follow-up was 36 months (3 to 88 months) for both cohorts. Disease specific survival at five years was observed at 85.2 and 74.6 percent in the MMC-HT and the RC cohorts respectively, whilst overall survival figures were 61.9 versus 68.4 percent.

Conclusions: "MMC-HT is both feasible and safe if offered to well selected patients. It provides durable long-term outcomes compared to RC for HR-NMIBC.....there is a clear advantage in complication rates favouring MMC-HT over RC without a significant difference in disease specific or overall survival."

The efficacy and safety of mitomycin-C hyperthermia in the treatment of high risk (HR) non-muscle invasive bladder cancer (NMIBC) in a single regional centre.

A report on seven year experience of MMC-HT, and aim to establish whether it is efficacious in this high risk cohort of patients.

100 patients with HR NMIBC were treated with MMC-HT (3 patients did not complete induction regimen due to side effects,  1 patient developed clinical metastases during the first two weeks of induction course).  96 patients completed induction treatment and had cystoscopy and biopsy at 3 months.  Of these 96 patients, 84 had failed BCG or were intolerant to it.  Patients were given an induction regimen with weekly treatments for 6-8 weeks with MMC-H on an outpatient basis with the Synergo® system SB-TS 101.

Median follow up was 34 months (3 to 88 months). 72% of patients (69/96) had complete response at 3 months, 10% had partial response (10/96) and 18% (17/96) had recurrence. Twenty patients had radical cystectomy.  Eighteen patients had organ confined disease and two patients had T3 disease at histology.  Only one patient developed recurrence of disease after cystectomy. No patients suffered a Clavien-Dindo Complication above 2.

Conclusions: "MMC-HT has comparable five year survival to radical cystectomy in the treatment of high risk superficial bladder cancer after BCG failure. It is well tolerated and can be delivered effectively by a regional centre. In those patients who are medically fit, cystectomy is still a potentially curative option for those patients who fail MMC-HT."
