Cost analysis of minimally invasive radical hysterectomy for cervical cancer performed by a single surgeon in an Italian center: an update in gynecologic oncological field

The objective of this study is to perform an economic analysis and examine the influence of procedural volume of our hospital, evaluating the accounting systems of Robotic radical hysterectomy (RRH) vs Laparoscopic radical hysterectomy (TLRH) in patients with cervical carcinoma, due to the costs widely variable and lack in literature. Costs were collected prospectively, from March 2010 to March 2016. Direct costs were determined by examining the overall medical pathway for each type of intervention. 52 patients with cervical carcinoma, which were matched by age, body mass index, tumor size, International Federation of Gynecology and Obstetrics (FIGO) stage, comorbidity, previous neoadjuvant chemotherapy, histology type, and tumor grade to obtain homogeneous samples. Surgical time was similar for both the groups. RRH was associated with a significantly less (EBL) estimated blood loss (P = 0.000). The overall median length of follow-up was of 59 months. The cost of the robot-specific supplies was €2705 per intervention. When considering overall medical surgical care, the patient treatment average cost of an RRH was €5650,31 with an hospital stay (HS) of 3.58 days (SD ± 1) vs €3750.86 for TRLH, with an HS of 4.27 days (SD ± 1.79). Our results are similar to Finnish data; the costs of robot-assisted hysterectomies were 1.5 times higher than TLRH. The main drivers of additional costs are robotic disposable instruments, which are not compensated by the hospital room costs and by an experienced team staff. Implementation of strategies to reduce the cost of robotic instrumentation is due. RRH resulted less expensive than robotic simple hysterectomy for benign conditions.
