Real-world prostate-specific antigen reduction and survival outcomes of metastatic hormone-sensitive prostate cancer patients treated with apalutamide: An observational, retrospective, and multicentre study.

Background: Metastatic hormone-sensitive prostate cancer (mHSPC) treatment has changed drastically during the last years with the emergence of androgen receptor-targeted agents (ARTAs). ARTA combined with androgen deprivation therapy has demonstrated better oncological and survival outcomes in these patients. However, the optimal choice among different ARTAs remains uncertain due to their analogous efficacy. Objectives: The objective of this study was to describe prostate-specific antigen (PSA) response and oncological outcomes of patients with mHSPC treated with apalutamide. Material and methods: Medical records from three different hospitals in Spain were used to conduct this study. Patients diagnosed with mHSPC and under apalutamide treatment were included between March 2021 and January 2023. Data regarding PSA response, overall survival (OS), and radiographic progression-free survival (rPFS) were collected and stratified by metastasis volume, timing, and stating. Results: 193 patients were included; 34.2% of patients were de novo mHSPC, and the majority was classified as m1b. The 18-month OS and rPFS were 92.5% and 88.9%, respectively. Patients with PSA levels ≤0.2 ng/ml showcased an 18-month OS rate of 98.7%, contrasting with 65.3% for those with PSA >0.2 ng/ml. Similar trends emerged for rPFS (97.4% and 53.7%, respectively). When differentiating between low-volume and high-volume metastasis, the OS rate stood at 98.4% and 80.7%, respectively, while the rPFS rates were 93% and 81.6%, respectively. No significant differences were found between groups stratified by metastasis timing. Conclusion: This real-world study on patients with mHSPC treated with apalutamide plus androgen deprivation therapy revealed robust oncological outcomes, aligning with the emerging evidence. The study's hallmark finding highlights the significance of rapid and deep PSA response as a predictor of improved oncological and survival outcomes.

Personalised indocyanine-guided lymphadenectomy for prostate cancer: a randomised clinical trial.

OBJECTIVES: To study the safety and efficacy of a personalised indocyanine-guided pelvic lymph node dissection (PLND) against extended PLND (ePLND) during radical prostatectomy (RP). PATIENTS AND METHODS: Patients who were candidates for RP and lymphadenectomy, with intermediate- or high-risk prostate cancer (PCa) according to the National Comprehensive Cancer Network guidelines, were enrolled in this randomised clinical trial. Randomisation was made 1:1 to indocyanine green (ICG)-PLND (only ICG-stained LNs) or ePLND (obturator fossa, external, internal, and common iliac and presacral LNs). The primary endpoint was the complication rate within 3 months after RP. Secondary endpoints included: rate of major complications (Clavien-Dindo Grade III-IV), time to drainage removal, length of stay, percentage of patients classified as pN1, number of LNs removed, number of metastatic LNs, rate of patients with undetectable prostate-specific antigen (PSA), biochemical recurrence (BCR)-free survival, and rate of patients with androgen-deprivation therapy at 24 months. RESULTS: A total of 108 patients were included with a median follow-up of 16 months. In all, 54 were randomised to ICG-PLND and 54 to ePLND. The postoperative complication rate was higher in the ePLND (70%) vs the ICG-PLND group (32%) (P < 0.001). Differences between major complications in both groups were not statically significant (P = 0.7). The pN1 detection rate was higher in the ICG-PLND group (28%) vs the ePLND group (22%); however, this difference was not statistically significant (P = 0.7). The rate of undetectable PSA at 12 months was 83% in the ICG-PLND vs 76% in the ePLND group, which was not statistically significant. Additionally, there were no statistically significant differences in BCR-free survival between groups at the end of the analysis. CONCLUSIONS: Personalised ICG-guided PLND is a promising technique to stage patients with intermediate- and high-risk PCa properly. It has shown a lower complication rate than ePLND with similar oncological outcomes at short-term follow-up.

Bilateral Seminal Vesicle Invasion Is Not Associated with Worse Outcomes in Locally Advanced Prostate Carcinoma.

Background and Objectives: Patients with seminal vesicle invasion (SVI) are a highly heterogeneous group. Prognosis can be affected by many clinical and pathological characteristics. Our aim was to study whether bilateral SVI (bi-SVI) is associated with worse oncological outcomes. Materials and Methods: This is an observational retrospective study that included 146 pT3b patients treated with radical prostatectomy (RP). We compared the results between unilateral SVI (uni-SVI) and bi-SVI. The log-rank test and Kaplan-Meier curves were used to compare biochemical recurrence-free survival (BCR), metastasis-free survival (MFS), and additional treatment-free survival. Cox proportional hazard models were used to identify predictors of BCR-free survival, MFS, and additional treatment-free survival. Results: 34.93% of patients had bi-SVI. The median follow-up was 46.84 months. No significant differences were seen between the uni-SVI and bi-SVI groups. BCR-free survival at 5 years was 33.31% and 25.65% (p = 0.44) for uni-SVI and bi-SVI. MFS at 5 years was 86.03% vs. 75.63% (p = 0.1), and additional treatment-free survival was 36.85% vs. 21.93% (p = 0.09), respectively. In the multivariate analysis, PSA was related to the development of BCR [HR 1.34 (95%CI: 1.01-1.77); p = 0.03] and metastasis [HR 1.83 (95%CI: 1.13-2.98); p = 0.02]. BCR was also influenced by lymph node infiltration [HR 2.74 (95%CI: 1.41-5.32); p = 0.003]. Additional treatment was performed more frequently in patients with positive margins [HR: 3.50 (95%CI: 1.65-7.44); p = 0.001]. Conclusions: SVI invasion is an adverse pathology feature, with a widely variable prognosis. In our study, bilateral seminal vesicle invasion did not predict worse outcomes in pT3b patients despite being associated with more undifferentiated tumors.

Simultaneous pancreas-kidney transplantation: Early complications and long-term outcomes - a single-center experience.

INTRODUCTION: This study aimed to assess the prevalence and severity of complications after simultaneous pancreas-kidney transplantation (SPKT) and to evaluate its influence on both grafts' long-term results. METHODS: This was an observational, retrospective study including 39 consecutive SPKT cases from 2000-2018. Complications were classified into kidney-related and pancreas-related. The severity of complications was assessed using the modified Clavien-Dindo scale. Kaplan-Meier curve analysis and log-rank tests were used. Cox regression was performed for the multivariate analysis. RESULTS: All 39 recipients had long-term type I diabetes. Twenty-one (53.8%) patients suffered a Clavien-Dindo ≥IIIa complication. Most complications were pancreas-related, with 17 (43.6%) patients suffering from one. Kidney-related major complications were seen in 11 (28.2%) patients. Patient survival at one, five, and 15 years was 89.7%, 87.1%, and 83.9%, respectively; kidney survival was 87.1%, 81.4%, and 73.6%, respectively; and pancreas survival was 76.9%, 71.3%, and 72%, respectively. Pancreas graft survival was influenced by the presence of major postoperative complications; patients and kidney graft survival were not. CONCLUSIONS: Complications after SPKT influence pancreas graft survival. Despite the high rate of complications, our results suggest that patient and kidney graft survival may not be affected by complications.

Benign renal schwannoma: Case report and literature review.

Renal schwannoma is a very infrequent tumor. It is usually benign and it does not have any specific symptoms or imaging characteristics. Its final diagnosis is usually made after surgery. We present a 66 year-old-man that was referred to our center after the casual finding of a renal mass. With a suspected diagnosis of a renal cell carcinoma, a partial nephrectomy was performed. The histological study revealed the final diagnosis of a benign renal schwannoma.

Bacillus Calmette-Guérin in Immunosuppressed Patient with High-Grade Nonmuscle Invasive Bladder Carcinoma.

Due to their immunosuppressed status, solid organ transplant recipients are a special group of patients with an incidence of bladder cancer greater than the rest of the population, especially in the first 6 years after transplantation. Also, treatment with Bacillus Calmette-Guérin, a reference therapy in nonmuscle invasive high-risk bladder cancer, may be less effective in this group of patients and could cause more adverse effects. However, the data published so far and the experience initiated in the Virgen de la Arrixaca Clinical University Hospital do not support these hypotheses.
