Abstract
INTRODUCTION: Retroperitoneal lymph node dissection (RPLND) is a standard treatment in the management of metastatic testicular cancer. Due to modified treatment algorithms, it is becoming less frequent. MATERIALS AND METHODS: We analyzed data from the nationwide German hospital billing database covering 2006-2015. Cases with a testicular cancer diagnosis combined with RPLND were included. We assessed the length of hospital stay (LOS), blood transfusion, and in-hospital mortality stratified for surgical approach, hospital characteristics, and annual caseload. Annual hospital caseload categories were defined as low (< 4), medium (4-10), and high (> 10). We supplemented tumor incidence and staging data from the German cancer registry (60% of population). RESULTS: 4926 cases were included with decreasing annual caseload numbers from 623 in 2006 to 382 in 2015. The incidence of testicular cancer and higher tumor stages remained stable. High-volume hospitals performed 19.4%, medium-volume hospitals 43.7%, and low-volume hospitals 36.8% RPLNDs. Low- abd medium-volume hospitals declined, while high-volume hospitals (n = 5) maintained their annual caseload. Overall in-hospital mortality was 0.47%. Blood transfusion rates were higher in high-volume centers assumedly due to selection of more complex cases. However, high-volume hospitals showed a shorter LOS with 10.5 vs. 11.2 (medium volume), and 12.7 days (low volume). CONCLUSION: Total numbers of RPLND have declined from 2006 to 2015, while tumor incidences and stages remained fairly stable. Constant reduction of indication in guidelines contributes to this finding. High-volume hospitals achieve shorter hospital stays in spite of assumedly more complex and extensive cases. There is a modest trend towards unregulated centralization.
