g., Vc, Vp, and Q) can be predicted in the allometry. Although PBPK and allometric methods have long been used to predict Vd, there is no consensus on method choice. CID44216842 supplier When the discrepancy between PBPK-predicted Vd and allometry-predicted Vd is huge, physiological plausibility of all input and output data (e.g., r2-value of the allometric curve) may be reviewed for careful decision making.
In the global Phase-3 Selective Prostate Androgen Receptor Targeting with ARN-509study, apalutamide plus ongoing androgen deprivation therapy (ADT) significantly increased metastasis-free survival (MFS) and improved other clinical outcomes in men with nonmetastatic castration-resistant prostate cancer (nm-CRPC) who were at high risk of developing metastases. In this subpopulation analysis of Selective Prostate Androgen Receptor Targeting with ARN-509 study, the efficacy and safety of apalutamide plus ADT were evaluated in Japanese patients with nm-CRPC.

The primary efficacy end point was MFS. Secondary efficacy end points were time to metastasis, progression-free survival, symptomatic progression, initiation of cytotoxic chemotherapy, and overall survival. Safety and pharmacokinetic parameters were also assessed.

Fifty-five Japanese patients with ongoing ADT were randomized (apalutamide n=34, placebo n=21). Median treatment duration was 5.7months in the apalutamide group and 11.0months in the placebo grnm-CRPC who are at high-risk of developing metastases.
Multiparametric prostate magnetic resonance imaging (mpMRI)-guided fusion prostate biopsyis an emerging technique in the diagnosis of prostate cancerand provides extensive information on the prebiopsy anatomy of the prostate, anus, and rectum. We aimed to investigate the clinical and anatomical risk factors aggravating the pain experienced by patients undergoing mpMRI-guided fusion prostate biopsy.

The prospective study included 319 patients aged 45-75years who had a prostate-specific antigen<10ng/ml and a Prostate Imaging Reporting and Data System≥3 lesion and underwent combined biopsy (targeted biopsy+12-core standard prostate biopsy) under local anesthesia (intrarectal lidocaine gel+periprostatic nerve block). Immediately after the biopsy procedure, pain assessment was achieved using Visual Analog Scale (VAS). The relationship between the VAS and 13 clinical parameters was evaluated using ordinal logistic regression analysis.

The 319 patients had a mean age of 62.39±6.98years and a median prostate-specific antigen level of 7.20 (range, 5.20-8.50) ng/ml. The VAS was found to be correlated with 4 of 13 parameters, including (i) a shorter prostate-anus surface distance(cutoff value, 55.5mm), (ii) a narrower anorectal angle(cutoff value, 106.5°), (iii) a larger total prostate volume (cutoff, 61.6mm
), and (iv) having no history of prior biopsy (biopsy-naive patients).

Anatomical measurements that can be achieved by using mpMRI images (TPV, PASD and ARA) may be useful in the identification of patients at an increased risk of pain during biopsy and also in taking analgesic precautions in such patients.

To investigate the clinical and pathological predictive factors affecting biochemical recurrence (BCR) after radical prostatectomy (RP) in patients with positive and negative surgical margin (SM).

Patients who underwent RP were retrospectively reviewed for the study. Demographic, clinical, pathological and oncological data were evaluated. All data were compared between patients with positive SM and negative SM to detect factors associated with SM status. Later, patients were divided into two groups as BCR-negative and BCR-positive groups. Data were separately compared between BCR groups for all patients, SM-negative and SM-positive patients, respectively.

A total of 254 patients with a mean age of 63.5years and the mean prostate-specific antigen of 10.9ng/ml were evaluated in the study. SM positivity was found to be an independent prognostic factor for BCR (p=0.013, Odds Ratio (OR) 0.267, 95% Confidence Interval (CI) 0.094-0.755). In SM-positive patients, biopsy Gleason Score and International Society of Urological Pathology grade were found to be independent predictive factors for BCR (p<0.05). However, only tumor to SM distance (TSMD) was found to be an independent risk factor for BCR (p=0.024) in SM-negative patients. The predictive cutoff value of the TSMD was found to be 75μm for BCR (100% sensitivity and 63.9% specificity) (AUC=0.803, p=0.024). Although all of 46 patients with >75μm TSMD were recurrence free, 5 of 31 patients with <75μm TSMD had BCR (p=0.009; OR 0.839 CI 0.719-0.979).

High Gleason Score and International Society of Urological Pathology grade of biopsy were found to be associated with BCR in SM-positive patients. For SM-negative patients, only TSMD was found to be associated with BCR after RP.

Conditional survivalis defined as the likelihood of subsequent survival given the precondition of having already survived a certain length of time. Most analyses of conditional survival in prostate cancerare not clinically applicable because they do not analyze outcomes conditioned on the durability of cure after treatment. We evaluated the conditional probability of biochemical recurrence (BCR)-free survival (C-BCRFS) after radical prostatectomy (RP) for prostate cancer according to the National Comprehensive Cancer Network risk classification and prognostic factors in patients who survived several years without BCR.

Between January 2009 and December 2018, 877 patients with complete clinicopathologic and follow-up data were included. Using the Kaplan-Meier estimation, the probabilities of C-BCRFS after RP were estimated in patients who did not experience BCR at 0-4years. C-BCRFS was analyzed according to the National Comprehensive Cancer Network risk classification and compared using the log-rank test. Prognostic factors at each year without BCR were evaluated using multivariable Cox regression analysis.
