Management of muscle-invasive bladder cancer.

The incidence of muscle-invasive bladder cancer (MIBC) is increasing. Many different and multimodal novel treatment options were brought on the way since the beginning of a new era in the early 1980s, when the neobladder as a common option for urinary diversion had been induced. In addition to open radical cystectomy and urinary diversion, recently, minimal invasive surgery has been implemented in experienced centers and led to promising results in short term follow-up, awaiting confirmation in larger cohorts. Pelvic lymphnode dissection can cure patients with low metastatic load. Expansion of pelvic lymphonodal dissection and its influence on survival was discussed intensively with trends to a moderate enlargement of the standard field. Outcome in nodal positive disease is remaining poor, while 90% of patients with multiple lymphnode metastases will suffer from systemic progress 5 years after diagnosis. In the last decade, treatment regimens based on neoajuvant or adjuvant chemotherapy were published with different results on efficiency. To decide whether to treat with surgery alone, or to offer perioperative systemic cytostatic therapy, is one of the unanswered questions. Furthermore, bladder preserving techniques are still optional for patients with small unifocal lesions or the medically unfit cohort. This review summarizes current data and aims to help guiding through several available recommendations on therapy and management of MIBC.

[The use of Surgisis® optimizes and simplifies partial nephrectomy for large renal tumors]. / Anwendung von Surgisis® zur Optimierung und Vereinfachung der Nierenteilresektion bei größeren renalen Neoplasmen.

BACKGROUND: With lower rates of postoperative renal failure, diabetes and cardiovascular disease, partial nephrectomy achieves longer overall survival and equally long tumor-specific survival. It is thus the current gold standard treatment for renal tumors and now also for those ≥ 4 cm in size. The main complications of nephron-sparing surgery, particularly for large and centrally located tumors, are postoperative parenchymal bleeding and urinary fistulas after opening the urinary collecting system (UCS). MATERIAL AND METHODS: Between August 2003 and April 2012, 76 partial nephrectomies for tumors ≥ 4 cm in size were performed using porcine small intestinal submucosa (SIS, Surgisis®) to close the capsular, renal and in some cases, UCS defects. RESULTS: The median tumor size was 5.0 cm (range 4.0-13.0 cm) and the intervention was performed with warm ischemia in 25 cases (32.8 %), with cold perfusion in 16 cases (21.2 %) and without ischemia in 35 cases (46.0 %). A total of 4 patients (5.5 %) developed postoperative urinary fistulas and 4 (5.5 %) required revision surgery because of significant postoperative bleeding. There were no local infections or allergic reactions to the foreign material. CONCLUSIONS: Surgisis® enables a quick and technically uncomplicated closure of the renal defect after partial nephrectomy for tumors. It has the potential to further minimize postoperative bleeding and urinary fistulas and to facilitate the intervention to the extent that nephron-sparing surgery will gain broader acceptance even in patients with tumors ≥4 cm in size.

[Palliative care and medicamentous therapy during the final episode of life]. / Palliativmedizin und medikamentöse Therapie in der Sterbephase.

The idea of modern palliative care goes back to the times of Dame Cicely Mary Strode Saunders in 1967, a British nurse and physician. Modern palliative care is a multimodal therapeutic and supportive concept for the patient, when curative care has failed or seems to be not reasonable. In this article we review the basics of current palliative care and focus in particular on specific medicamentous therapy during the final episode of life.
