Preoperative %p2PSA and Prostate Health Index Predict Pathological Outcomes in Patients with Prostate Cancer Undergoing Radical Prostatectomy.

ABSTRACT: To evaluate the predictive accuracy of the %p2PSA and prostate health index (PHI) in predicting aggressive pathological outcomes in patients with prostate cancer (PCa) undergoing radical prostatectomy (RP), we enrolled 91 patients with organ-confined PCa who were treated with robot-assisted RP. p2PSA levels and the PHI were investigated for their ability to predict pathological results. The %p2PSA and PHI were both significantly higher in patients with ?pT3 disease, high-risk disease, positive surgical margin, or seminal vesical invasion (SVI). In univariable analysis, p2PSA derivatives were significant predictors of the presence of ?pT3 disease, high-risk disease, positive surgical margin, and SVI. To predict adverse pathological outcomes at a sensitivity of 90%, p2PSA derivatives had higher specificity than standard PSA derivatives. In multivariable analysis, additional increases in the area under the receiver operating characteristic curve (AUC) were observed with the %p2PSA and PHI for ?pT3 disease, high-risk disease, and positive surgical margin (8.2% and 2.7%, 6.2% and 4.1%, and 8.6% and 5.4%, respectively). A PHI ?61.26 enhanced the predictive accuracy of the model for SVI by increasing the AUC from 0.624 to 0.819 (p?=?0.009). The preoperative %p2PSA and PHI accurately predict adverse pathological results and are useful for decision-making.

Project description:Background and objectiveProstate cancer (PCa) is one of the most common malignant tumors in men. Geriatric Nutritional Risk Index (GNRI) is an objective index for evaluating nutritional status of elderly people over 65 years old. The aim of the current study was to explore the correlation and predictive value between GNRI and postoperative recovery and complications in PCa patients undergoing laparoscopic radical prostatectomy (LRP).MethodsTaking 98 as the GNRI boundary value, 96 PCa patients (aged≥65 y) undergoing LRP in the Department of Urology, Affiliated Hospital of North Sichuan Medical College from January 2018 to December 2020 were grouped into malnutrition group (MNg, 34 patients, 35.4%) and normal nutrition group (NNg, 62 patients, 64.6%). Basic information, laboratory examination indexes, operation conditions, postoperative complications and postoperative recovery indexes of patients were recorded and retrospectively analyzed. Clavien-Dindo Classification System (CDCS) was used to assess postoperative complications. T-test was used to analyze differences between the two groups. ROC curve was generated to determine the predictive value of GNRI for postoperative complications.ResultsPercentage of complications was significantly higher in MNg group compared with that in NNg group (P < 0.01). The average grade based on CDCS was significantly lower in NNg group compared with that in MNg group (P < 0.01). Body weight, Body Mass Index (BMI), preoperative hemoglobin value (HGB), serum albumin (ALB) values of MNg and NNg were significantly positively correlated with GNRI (P<0.01). Incidence and severity of postoperative complications of MNg patients were significantly higher compared with those of NNg patients (P<0.05). Average hospitalization cost of MNg patients was higher in MNg patients compared with that of NNg patients (P<0.05). Duration of post-anesthesia care unit (PACU), duration of antibiotic use and duration of indwelling drainage tube were longer in MNg patients compared with those in NNg patients (P<0.05). Furthermore, volume of indwelling drainage tube was higher in MNg patients compared with that in NNg patients (P<0.05).ConclusionGNRI is an effective and reliable tool for evaluation of preoperative nutritional status of prostate cancer patients. The findings showed that GNRI is correlated with postoperative recovery and complications, and is an effective predictive marker.

Project description:BackgroundThe impact of senior age on prostate cancer (PCa) oncological outcomes following radical prostatectomy (RP) is controversial, and further clinical factors could help stratifying risk categories in these patients.ObjectiveWe tested the association between endogenous testosterone (ET) and risk of PCa progression in elderly patients treated with RP.DesignData from PCa patients treated with RP at a single tertiary referral center, between November 2014 and December 2019 with available follow-up, were retrospectively evaluated.MethodsPreoperative ET (classified as normal if >350 ng/dl) was measured for each patient. Patients were divided according to a cut-off age of 70 years. Unfavorable pathology consisted of International Society of Urologic Pathology (ISUP) grade group >2, seminal vesicle, and pelvic lymph node invasion. Cox regression models tested the association between clinical/pathological tumor features and risk of PCa progression in each age subgroup.ResultsOf 651 included patients, 190 (29.2%) were elderly. Abnormal ET levels were detected in 195 (30.0%) cases. Compared with their younger counterparts, elderly patients were more likely to have pathological ISUP grade group >2 (49.0% versus 63.2%). Disease progression occurred in 108 (16.6%) cases with no statistically significant difference between age subgroups. Among the elderly, clinically progressing patients were more likely to have normal ET levels (77.4% versus 67.9%) and unfavorable tumor grades (90.3% versus 57.9%) than patients who did not progress. In multivariable Cox regression models, normal ET [hazard ratio (HR) = 3.29; 95% confidence interval (CI) = 1.27-8.55; p = 0.014] and pathological ISUP grade group >2 (HR = 5.62; 95% CI = 1.60-19.79; p = 0.007) were independent predictors of PCa progression. On clinical multivariable models, elderly patients were more likely to progress for normal ET levels (HR = 3.42; 95% CI = 1.34-8.70; p = 0.010), independently by belonging to high-risk category. Elderly patients with normal ET progressed more rapidly than those with abnormal ET.ConclusionIn elderly patients, normal preoperative ET independently predicted PCa progression. Elderly patients with normal ET progressed more rapidly than controls, suggesting that longer exposure time to high-grade tumors could adversely impact sequential cancer mutations, where normal ET is not anymore protective on disease progression.

Project description:BackgroundThis study aimed to assess the longitudinal health-related quality of life (HRQOL) using the Expanded Prostate Cancer Index Composite (EPIC) and HRQOL change between the nerve-sparing technique in Japanese men treated with robot-assisted radical prostatectomy (RARP).MethodsA total of 573 patients who received RARP were included in this study. EPIC questionnaire was administered before treatment and up to 36 months after RARP. Clinical recovery was defined as half of the standard deviation of the baseline score for each domain. We divided all patients into recovery group or nonrecovery group. The time from survey to each domain recovery was calculated using the Kaplan-Meier method. We compared the sexual and urinary score change between groups using analysis of variance to confirm the effect of nerve-sparing technique.ResultsThe median age was 67 years (interquartile range, 62-71 years). The mean score of all urinary domains worsened noticeably after 1 month. All postoperative urinary summary, function, and incontinence scores were significantly lower than preoperative scores up to 3 years post-RARP. Postoperative sexual summary and functional scores were significantly lower than preoperative score at all follow-up times throughout the 36 months. The recovery rate for the urinary incontinence domain was the lowest (44.5%), whereas the recovery rate for the urinary irritative-obstructive domain was the highest (73.7%). In the sexual domain, the bother domain had a higher recovery rate (73.0%) than the functional domain (29.7%). Although the recovery of sexual domains was slower compared with other domains, by 36 months after RARP, almost all values had recovered. Compared with other technique groups, bilateral intrafascial nerve-sparing group showed significantly decreased change in subscale scores before and after RARP in several sexual and urinary domain.ConclusionThe time course and extent of functional and bother domain recovery documented in this study may prove useful for RARP patient selection in Japan.
