Abstract
Background
To determine the peri-operative safety and oncological value of robotic-assisted radical cystectomy (RARC) for older and younger patients in an initial Japanese RARC series.
Methods
We retrospectively analyzed the demographics, complications, peri-operative and oncological outcomes of 253 consecutive patients with bladder cancer who underwent RARC at 34 institutions in Japan between April 2009 and March 2017. The patients were assigned to groups according to ages at surgery of < 70 (younger; n = 125) and ≥ 70 (older; n = 128) years.
Results
Mean Charlson comorbidity index (p = 0.045) and the incidence of a history of previous abdominal surgery (p = 0.002) were significantly higher, whereas a history of neoadjuvant chemotherapy (p = 0.028) and neobladder (p < 0.001) were significantly lower in the older group. Mean total operative time was significantly shorter (p = 0.019) and mean estimated blood loss (p = 0.013) was significantly lower in the older group. Post-operative Grade ≥ II complications were comparable at 0–30, 31–90 and 91 days after surgery despite urinary tract associations. Rates of positive surgical margins and mean numbers of removed lymph nodes were comparable between the two groups. Although 5-year overall survival rates were significantly lower (p = 0.03) for older patients, 5-year cancer-specific (p = 0.10) and recurrence-free survival rates were comparable (p = 0.20) between the groups.
Conclusion
Using RARC potentially allows the application of less invasive procedures and cancer control for septuagenarian patients that are equivalent to those for younger patients.
