Comparative efficacy of Bacillus Calmette-Guérin instillation and radical cystectomy treatments for high-risk non-muscle-invasive urothelial cancer classified as high-grade T1 in initial and repeat transurethral resection of bladder tumor.

Objective: To compare the differential therapeutic effects of Bacillus Calmette-Guérin (BCG) instillation and radical cystectomy (RC) for high-risk non-muscle-invasive urothelial cancer (NMIBC) classified as high-grade T1 in initial and repeat transurethral resection of bladder tumors (TURBT) and to construct a prediction model. Methods: We retrospectively analyzed the clinical data of patients with malignant bladder tumors treated at the First Affiliated Hospital of Soochow University from January 2016 to December 2017 and compared the differences in 1-year, 2-year, 3-year, 5-year, and comprehensive overall survival (OS) and progression-free survival (PFS) between BCG instillation treatment and RC treatment. Survival curves were drawn to show differences in OS and PFS between the two groups. Concurrently, univariate and multivariate COX analyses were performed to identify risk factors affecting OS and PFS, and a nomogram was created. Results: In total, 146 patients were included in the study, of whom 97 and 49 were in the BCG and RC groups, respectively. No statistical differences were observed in the 1- and 2-year OS and PFS between the two groups, whereas significant statistical differences were found in the 3-year, 5-year, and comprehensive OS and PFS. Survival curves also confirmed the statistical differences in OS and PFS between the BCG and RC groups. Multivariate COX analysis revealed that the treatment method, concomitant satellite lesions, and albumin-to-alkaline phosphatase ratio (AAPR) were independent risk factors affecting OS and PFS. The nomogram that was further plotted showed good predictive ability for OS and PFS. Conclusion: For patients who exhibit high-level T1 pathology after both initial and repeat TURBT, especially those with low AAPR, and concomitant satellite lesions, choosing RC as a treatment method offers a better prognosis.

Two-year Outcomes after Transurethral Prostate Resection Post-prostatic Artery Embolization Versus Transurethral Prostate Resection Alone For Giant Benign Prostatic Hyperplasia.

PURPOSE: To compare the long-term (two-year) efficacy between transurethral resection of the prostate (TURP) after prostatic artery embolization (PAE) and TURP only for patients with giant (>100 mL) benign prostatic hyperplasia. MATERIALS AND METHODS: We retrospectively analyzed data from 61 and 150 patients with giant benign prostatic hyperplasia treated with PAE+TURP or TURP alone, respectively, from January 2015 to March 2020. We compared index changes before and after surgery. RESULTS: The operative time, intraoperative blood loss, postoperative bladder irrigation time, and catheter retention time in the PAE+TURP group were lower than those of the TURP group, while the speed of resection of the lesion and hospitalization costs were more significant (P < 0.05). International prostate symptom score (IPSS), quality of life (QoL), prostate volume, maximum urinary flow rate, detrusor pressure of maximum urinary flow rate, prostate-specific antigen, and urodynamic obstruction were better in the PAE+TURP group than the TURP group at 24 months (P < 0.05). Regarding IPSS and QoL scores at 24 months postoperatively compared with the preoperative period, the PAE+TURP group was better than the TURP group in terms of the storage period, voiding period, and QoL (P < 0.05). The distribution of postoperative adverse event severity classes was comparable between the groups (P = 0.984). CONCLUSION: In contrast to TURP alone, PAE + TURP is more expensive but provides better postoperative outcomes; there is no significant difference in terms of the severity grade distribution of postoperative complications.

Small nucleolar RNA host gene 25 is a long non-coding RNA helps diagnose and predict outcomes in prostate cancer.

BACKGROUND: The role of a long non-coding RNA called small nucleolar RNA host gene 25 (SNHG25) has been studied in some tumor types but the correlation between SNHG25 and PCA remains unknown. METHODS: The relationship between clinicopathologic characteristics and SNHG25 expression was evaluated using The Cancer Genome Atlas data. The binary classifier value of SNHG25 was calculated using areas under receiver operating characteristic (ROC) curves. Outcomes were evaluated using Kaplan-Meier and Cox regression analyses. Gene set enrichment was performed to identify potential SNHG25 functions. RESULTS: SNHG25 expression was significantly increased in PCA and correlated with age, primary therapy outcome, N stage, Gleason score, and residual tumor (p < 0.05). ROC curves demonstrated the effect of SNHG25 on diagnosis and outcomes (area under the curve = 0.923). Higher SNHG25 expression predicted shorter progression-free interval (PFI) (p < 0.001), and Cox regression showed that SNHG25 expression was an independent risk factor for reduced PFI (p = 0.028). SNHG25 expression was associated with mRNA and protein metabolism. CONCLUSIONS: SNHG25 expression increases significantly in PCA and is negatively associated with PFI. It is a potential diagnostic and prognostic biomarker in PCA.

The Effect of Tri-Modality Therapy with Bladder Preservation for Selective Muscle-Invasive Bladder Cancer.

Objectives: To compare the efficacy of complete transurethral resection of bladder tumor combined with postoperative chemoradiotherapy and radical cystectomy (RC) in the treatment of muscle-invasive bladder cancer (MIBC). Methods: This is a single-center, retrospective study. Clinical data of 125 patients with MIBC admitted to the First Affiliated Hospital of Soochow University from December 2012 to December 2015 were retrospectively analyzed, in which 79 patients (tri-modality therapy [TMT] group) received TMT bladder-sparing treatment, and 41 patients (RC group) received RC. The differences of probabilities for 1-year, 2-year, 5-year, and comprehensive overall survival (OS), progress-free survival (PFS) between 2 groups were calculated using Kaplan-Meier product limited estimates. Univariate and multivariate analyses were performed to detect potential risk factors for OS and PFS. Results: There was no statistical difference between the TMT group and RC group in the 1-year, 2-year, 5-year, comprehensive OS rate, and PFS rate. And survival analysis found no significant difference in OS and PFS between the 2 groups. Univariate analysis showed that age, TNM staging, and prognostic nutritional index (PNI) were associated with OS, while PNI was connected to tumor recurrence. Multiple linear regression analysis indicated that TNM staging and PNI were independent risk factors for OS. Conclusions: TMT can be used as an alternative to RC for MIBC patients under the premise of strict control of indications, rigorous postoperative follow-up, and timely salvage cystectomy. PNI was negatively correlated with OS and PFS, while TNM staging was positively correlated with OS.
