Abstract:
Objective:To evaluate the clinical value of the frozen section assessment of surgical margin in preserving urinary continence and erectile function during robotic radical prostatectomy (RARP).Methods:From Feb. 2022 to Jul 2023, 11 patients underwent RARP using intrafascial dissection technique and frozen section assessment in Beijing United Family Hospital. The median age was 64(61, 69)years, the median PSA was 8.0(6.0, 11.2)ng/ml, and the median IIEF-5 was 17.5(10.3, 22.0). All the patients were diagnosed with prostate cancer and PSMA-PET/CT showed negative for metastasis. The da Vinci Si platform, 4-arm, transabdominal anterior approach was applied in all cases. The prostate specimen was removed from the umbilical incision and submitted to the pathology department for frozen section assessment. If the frozen section assessment showed cancer in the surgical margin, a secondary resection of the ipsilateral periprostatic fascia and neurovascular bundle (NVB) was performed. Totally, 3 cases underwent secondary resection, who underwent unilateral NVB-sparing, and the other 8 cases underwent bilateral NVB-sparing surgery. In follow-up, the PSA, urinary continence and erectile function was assessed and recorded.Results:All the surgeries of 11 cases were successful, without convertion to open surgery. The median operation time was 260(225, 285)minutes, the median blood loss was 200(100, 300)ml, the median hospital stay was 4(3, 5)days. There was no over Clavien Dindo Ⅱ perioperative complications.The median catheter indwelling time was 12(10, 14) days, with 10 cases achieving full continence upon catheter removal. The median follow-up time was 10 months. The median PSA level at 3 months, 6 months and 9 months postoperatively was 0.017(0.006, 0.170)ng/ml, 0.015(0.006, 0.390)ng/ml, and 0.007(0.006, 0.650)ng/ml respectively. The median IIEF-5 at 3 months, 6 months and 9 months postoperatively was 0.017(0.006, 0.170)ng/ml, 0.015(0.006, 0.390)ng/ml, 0.007(0.006, 0.650)ng/ml respectively.The median IIEF-5 at 3 months, 6 months and 9 months post-operation was 5.0(4.5, 11.0), 7.5(4.3, 17.5), and 9.5(6.0, 17.5)respectively.Conclusions:The RARP combined with frozen section assessment of surgical margin has excellent safety profile and can achieve favorable clinical value in tumor control, NVB preserving, urinary continence and erectile function.
