RESUMO

OBJECTIVE: Comprehensive genomic profiling testing using a hybrid-capture next-generation sequencing is commonly used in clinical practice to employ precision medicine in cancer treatment worldwide. In this study, we aimed to analyze the profiles obtained using comprehensive genomic profiling testing that was performed in Japanese castration-resistant prostate cancer patients and to discuss the genetic findings in a real-world setting. METHODS: A total of 60 cases and 57 castration-resistant prostate cancer patients underwent comprehensive genomic profiling testing between 1 January 2021 and 31 December 2022. Four types of comprehensive genomic profiling testing were selected, and clinically significant cancer-specific gene alterations were identified. RESULTS: The median age of patients was 74 years, and the median prostate-specific antigen value at the time of submission was 18.6 ng/ml. Fifty-seven (95%) of 60 cases were metastatic castration-resistant prostate cancers, and 3 cases (5%) were non-metastatic. Among all genetic alterations, androgen-receptor alteration was the most frequently detected in 17 cases (28.3%), followed by 15 cases of TP53 (25.0%), 14 cases of CDK12 (23.3%), 10 cases of phosphatase and tensin homolog (16.7%) and 9 cases of ATM (15.0%) mutations. A total of 13 patients (21.7%) received systemic therapy according to the comprehensive genomic profiling testing results. Overall, the survival rate was significantly greater in the group treated through systemic therapy based on comprehensive genomic profiling testing compared with the group without new therapeutic treatment (P = 0.041). CONCLUSIONS: Comprehensive genomic profiling testing is recommended in castration-resistant prostate cancer patients identified as resistant to standard therapy as this can provide a new therapeutic option.

RESUMO

The clinical outcome of laparoscopic radical prostatectomy (LRP) was retrospectively investigated taking into consideration the surgeon's position during the procedure. The study cohort included 184 consecutive patients who had undergone LRP performed by a single surgeon from February 2013 to July 2018. During the study period,the surgeon stood alternately on either the left or right side of the patient. The D'Amico risk classification was low,intermediate and high in 26 (14.1%),45 (24.5%) and 113 (61.4%) patients,respectively. Mean surgical duration was 203.5 minutes and mean estimated blood loss was 437.6 ml. Nerve sparing (NS) was implemented in 82 (44. 6%) patients. The mean period of having an indwelling urethral catheter was 5. 0 days. Perioperative Clavien-Dindo degree ≥IIIa complications occurred in three (1.6%) patients. Except for cases with presurgical hormonal treatment,surgical margins were positive in 41 (22.3%) patients,among whom 23 (17.4%) had pT2 disease. The 5-year biochemical recurrence-free survival rate was 81.4%,and 84.8% of patients regained urinary continence at 12 months after surgery. Where the surgeon stood during LRP was not associated with significant differences in any parameter. However,the margin positive rate was higher on the side away from where the surgeon stood than the side closer to the surgeon (70.7% vs 29.3%). In conclusion,the position of the surgeon during LRP does not influence the outcome.

RESUMO

(Objectives)The usefulness of partial nephrectomy for renal tumors has been highlighted in various guidelines. Since 2006, we have been actively performing laparoscopic partial nephrectomy for renal tumors. We investigated the postoperative recurrence of renal tumors diagnosed as renal cell carcinoma after laparoscopic partial nephrectomy. (Patients and methods)From August 2006 to March 2020, 320 patients who underwent laparoscopic partial nephrectomy at our hospital and were pathologically diagnosed with renal cancer were included. A retrospective statistical study was conducted to analyze the postoperative recurrence. (Results)Postoperative recurrence was observed in 11 patients (3.4%). The median time to recurrence was 12 months (3-26 months), non-distant metastasis was observed in four cases (1.3%), and distant metastasis was observed in seven cases (2.2%). No statistically significant difference was found in the factors related to recurrence, in this study. (Conclusions)In this study, no statistically significant factors were found, but the higher the clinical stage, the higher the recurrence rate.
