Simultaneous or staged surgery in patients with kidney tumors and concomitant cardiac disease

Introduction To evaluate outcomes of simultaneous and staged surgery in patients with kidney tumors and concomitant cardiac disease. Material and methods Between October 2001 and October 2015, fifteen patients (Group 1) underwent simultaneous surgery and fourteen patients (Group 2) underwent staged surgery. 89.7% were males (26/29), and the mean age was 60.8 ±1.16 years. Locally advanced cancers (Stage III) were registered in the two groups in 11 vs. 3 patients (p = 0.016) and localized (Stage I) disease in 2 vs. 10 (p = 0.007), respectively. 18 patients (62%) were operated for coronary heart disease, while 10 patients (35%) underwent surgery for valvular heart disease. Nephrectomy was performed in 14rs 5 patients respectively (p = 0.003) while partial nephrectomy in 1rs 7 patients (p = 0.005). Results In the two groups, the 30-day mortality was 13% (2 cases) and 7% (1 case), p = 1.0, and major hospital complications were observed in 3 (20%) and 2 (14%) cases, respectively, p = 0.53. The median follow-up in Group 1 and Group 2 was 87 months (range, 23.3 to 146.8 months) and 39 months (range, 3.9 to 98 months), respectively, p = 0.001. Three-year overall survival was 73.3 ±11.4% (95% CI 50.5-96.1) and 77.9 ±11.3%, respectively, p = 0.70, and three-year disease-free survival was 83.9 ±10.4% and 75.0 ±21.7%, respectively, p = 0.91. Conclusions Simultaneous and staged surgery for kidney tumors and concomitant cardiac disease are feasible procedures. Patients with advanced tumors and complicated disease course can benefit from early intervention and consequently a simultaneous approach can be a preferred option for them. For localized renal tumors, staged surgery should be used.
