Due to the widespread usage of prostate-specific antigen screening, the number of patients diagnosed with prostate cancer is steadily increasing. Many factors such as high operating room demand, insurance reimbursement, patients' desire to assess multiple treatment options, and anxiety can cause delays in radical treatment. In this study, we examined the effect of delay from prostate biopsy to surgery on outcomes of men with localized prostate cancer. Materials and Methods: The data of 359 patients who underwent radical prostatectomy (RP) in our clinic between 2008 and 2017 were analyzed retrospectively. Surgical delay was defined as the time from transrectal ultrasound-guided prostate biopsy to surgery. Patients were divided into 3 groups according to the interval between prostate biopsy and RP (≤60, 61-120, ≥120 days) and classified according to the D'Amico risk classification. Results: A total of 248 patients were included in the study. Of these patients, 107 (43.1%) were operated within 60 days of biopsy, 113 (45.6%) 61-120 days after biopsy, and 28 (11.3%) over 120 days after biopsy. Statistical analysis of patients with follow-up of at least 12 months did not reveal a significant difference between the groups in terms of biochemical recurrence (p=0.06). A delay of over 120 days was not associated with adverse pathological or oncological findings at surgery for the low-risk group. Extraprostatic invasion increased significantly in the intermediate-risk group with longer surgical delay (p=0.044). Conclusion: Our data demonstrated that a delay of more than 120 days was not associated with adverse pathological outcomes in men with low-risk localized prostate cancer. For men with intermediate-risk disease, delays over 60 days were significantly associated with risk of extraprostatic invasion. Our findings indicate that RP should be performed within 60 days of biopsy for intermediate-risk patients.

Objective: To report our initial experience and short-term results in post-chemotherapy robot-assisted retroperitoneal lymph node dissection (RA-RPLND) for advanced testicular cancer. Material and methods:We analyzed prospectively collected data of 5 patients who underwent post-chemotherapy RA-RPLND between August 2017 and May 2018. All patients had a diagnosis of non-seminomatous germ cell tumor (NSGCT) of testis and received three or four cycles of BEP chemotherapy for their clinical stage IIC disease before the surgery. Perioperative parameters (operation time, estimated blood loss and intraoperative complications) and postoperative findings (change in hematocrit, duration of hospitalization and postoperative complications) were noted. Pathological outcomes and postoperative radiological imaging in the 3 rd month were investigated.Results: RA-RPLND was completed successfully in all patients, and none of them required conversion to open surgery or early intervention. The median operation time was 309 minutes (range, 275-360), and median estimated blood loss was 180 mL (range, 150-210). One patient required postoperative transfusion of 1U red blood cells. The histologic examination of the specimens revealed necrosis in 3, and mature teratoma in 2 patients. The median hospitalization time after surgery was 2 days. During a median follow-up of 10 months (range 7-12), there were no retroperitoneal recurrences or distant metastasis in radiological imaging. No major complication (Clavien ≥3) or death occurred. The only minor complication was transfusion of red blood cells in one patient (Clavien 2) and the overall complication rate was 20 percent. Conclusion:Post-chemotherapy RA-RPLND appears to be a feasible and oncologically safe procedure with acceptable operative morbidity. However, this technique should be applied in centers highly experienced in robotic surgery, considering that RPLND is a surgery with fatal complications.
