Our results indicated that older age (≥70 y) (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.02-1.27; p=0.025) and smaller prostate volume (OR, 0.97; 95% CI, 0.938-0.998; p=0.039) were associated with an increased incidence of IPC after TURP.

Our findings indicate that the prevalence of IPC may be higher among patients who undergo transrectal prostate biopsy before TURP than among those who undergo transperineal MRI/TRUS fusion prostate biopsy. Older age and smaller prostate volume were independent predictors of increasing the risk for IPC after TURP.

The second-to-fourth digit ratio (digit ratio), which is determined

, is associated with exposure to visible sunlight during early pregnancy and the season of birth. The digit ratio is also associated with benign prostatic hyperplasia (BPH) and prostate cancer. This suggests that BPH and prostate cancer may be related to the birth season. Therefore, this study aimed to determine whether prostate volume and prostate cancer were related to the birth season.

A total of 858 male patients with lower urinary tract symptoms were enrolled. The right digit ratio was measured, and the month of birth was surveyed. Serum prostate-specific antigen (PSA) levels were measured, and prostate volumes were measured by transrectal ultrasonography. Patients with suspected prostate cancer underwent prostate biopsy.

The mean age, digit ratio, prostate volume, and serum PSA level of 858 patients were 61.6 years, 0.947, 36.2 mL, and 4.24 ng/mL, respectively. Age, serum PSA levels, prostate biopsy rates, and cancer detection rates did not differ significantly according to the birth season. However, compared with the summer birth group, the winter birth group had lower digit ratios (0.951±0.040 vs. 0.941±0.040; p=0.014), larger prostate volumes (33.4±14.9 mL vs. 38.2±20.7 mL; p=0.008), and more prostate cancer (5.3% vs. 11.3%; p=0.031). Multivariate analysis showed that birth season independently predicted prostate cancer.

The relationships of birth season with prostate volume and prostate cancer may be due to differences in the amount of light exposure during early pregnancy.

To document nationwide serum prostate-specific antigen (PSA) testing trends over the past decade and to investigate the impact of testing on prostate cancer (PCa) detection.

Using annual National Health Insurance Service of Korea data for the period 2006 to 2016, PSA testing rates were investigated for men aged ≥40 years by decade, and associations between test rates and registered PCa cases were analyzed.

During the study period, the incidence of PCa increased about threefold (4,415 in 2006 to 15,046 in 2016). PCa incidences increased with age (p<0.001) and about 60% of cases were over 70 years old. Despite a fourfold increase in PSA testing (246,911 in 2006 to 937,548 in 2016), the average exposure rate among all men was only 7.27% in 2016, and the mean number of repeat tests for those that did not develop PCa during the study period was 2.9. https://www.selleckchem.com/products/bgj398-nvp-bgj398.html PSA test rates increased with age and in 2016 were 1.65% for those in their 40s, 4.90% for those in their 50s, 12.0% for those in their 60s, 19.2% for those in their 70s, and 21.6% for those aged ≥80. Regardless of the age groups, a significant association was found between PSA test numbers and the detection of PCas.

In contrast to the soaring incidence of PCa especially in those aged over 70 years who have a more frequent chance for PSA testing triggered by concomitant voiding symptoms, low exposure in general and among relatively younger men favors a countrywide screening policy.

The Korean population is rapidly aging, and the cancer burden is expected to change significantly. This study aimed to generate projections of incidence and mortality of major cancers among men in Korea until 2034, with a special focus on prostate cancer.

Cancer incidence data from 1999 to 2016 were obtained from the Korea National Cancer Incidence Database. Mortality data were obtained from Statistics Korea. The most common cancers among Korean men (stomach, colorectum, liver, lung and prostate) were analyzed. To predict the future trends of these cancers, the age-period-cohort method was conducted and extrapolated up to 2034.

In Korean men, prostate cancer was the fourth most commonly diagnosed cancer in 2016. Based on newly diagnosed cases, the leading cancer site in the year 2034 is expected to be the lung, and the prostate is expected to be the second most frequently diagnosed cancer among Korean men. Age-standardized incidence rates of the most common cancers in men, except prostate cancer, are expected to decrease until 2034. Lung cancer is projected to remain the most common cause of cancer-related mortality until 2034, and the highest estimated change in cancer deaths is expected to be for prostate cancer.

In Korea, the incidence and mortality of prostate cancer is expected to increase markedly in the period up to 2034, particularly in older men. Concerted efforts in screening, diagnosis, and treatment strategies should be considered by healthcare planners and providers.

To assess the safety and efficacy of gemcitabine and cisplatin as neoadjuvant chemotherapy followed by selective bladder preservation chemoradiotherapy in muscle-invasive bladder cancer (MIBC).

Patients with clinical T2-T4aN0M0 MIBC eligible for radical cystectomy and cisplatin-based chemotherapy were treated with gemcitabine 1,000 mg/m² on days 1, 8 and 15, and cisplatin 70 mg/m² on day 1 every 28 days for 3 cycles. After clinical re-staging with computed tomography scans and cystoscopy, patients with clinical complete response (CR) were eligible to proceed without cystectomy and receive bladder preservation chemoradiotherapy involving weekly cisplatin 10 mg/m² and up to 70.2 Gy of radiation. The primary endpoint of the present prospective phase II study was metastasis-free survival (MFS).

Between Oct 2017 and Nov 2019, a total of 138 MIBC patients were enrolled and treated with neoadjuvant gemcitabine/cisplatin. Neoadjuvant chemotherapy was well-tolerated, with fatigue, nausea, and pruritus being the most commonly observed adverse events. After completion of planned neoadjuvant chemotherapy, 54 patients with a clinical CR and 10 patients who did not have CR but refused surgery received bladder preservation chemoradiotherapy. With a median follow-up duration of 34 months (95% confidence interval [CI], 32%-36%), the 3-year MFS rate in 64 chemoradiotherapy patients was calculated to be 70% (95% CI, 58%-82%).

Neoadjuvant chemotherapy followed by selective bladder preservation chemoradiotherapy based on the clinical CR was feasible and efficacious in the treatment of MIBC.

To determine whether real-time ultrasonography-computed tomography (US-CT) fusion imaging can improve technical feasibility versus B-mode US and provide comparable outcomes of radiofrequency ablation (RFA) for T1a renal cell carcinoma (RCC) compared with laparoscopic partial nephrectomy (LPN).

Between June 2013 and August 2016, biopsy- or pathologically confirmed stage T1a RCCs were retrospectively reviewed. Of these, 39 cases were included in the RFA group, and 46 cases were included in the LPN group. In the RFA group, we evaluated tumor visibility and technical feasibility before RFA on a four-point scale on B-mode US and US-CT fusion images. After RFA, hospital days, creatinine value, complications, and disease-free survival rate were compared between the two groups. All results were analyzed by use of the Mann-Whitney U-test and Kaplan-Meier method.

Compared with B-mode US alone, real-time US-CT fusion significantly improved the tumor visibility score and overall mean technical feasibility grade (p<0.001). The 5-year disease-free survival rate was 97.4% and 97.8% in the RFA and LPN groups, respectively, and there was no statistically significant difference between groups (p=0.1). Mean periprocedural creatinine levels were significantly lower in the RFA group than in the LPN group. The number of hospital days was shorter in the RFA group. Minor complications were present in 5.1% of the RFA group and 13.0% of the LPN group, with no major complications.

US-CT fusion-image-guided RFA improved tumor visibility scores and overall mean technical validity and resulted in a comparable disease-free survival rate to LPN.

To perform a retrospective review of the clinicopathological features of patients with conventional and non-conventional renal cell carcinoma (cRCC and ncRCC).

A large prospectively maintained uro-oncological registry was accessed to extract clinicopathological data of patients diagnosed with renal tumors who subsequently underwent nephrectomy from 1990-2019. Demographics and operative parameters were extracted. Analyses of overall survival (OS) and cancer-specific survival (CSS) were performed using the Kaplan-Meier method. Cox proportional-hazards analysis was used to identify risk factors which influenced survival.

There were a total of 1,686 consecutive nephrectomies which was retrieved, with 1,286 cRCC and 400 ncRCC. The commonest ncRCC subtypes were papillary (n=198, 11.7%), clear cell papillary (n=50, 3.0%) and chromophobe (n=49, 2.9%) RCC. Kaplan-Meier estimates of OS were higher in cRCC (0.74; 95% confidence interval [CI], 0.71-0.78) than ncRCC (hazard ratio, 1.47; 95% CI, 1.16-1.87). Among individual subtypes, chromophobe RCC had the highest 5-year OS (0.90; 95% CI, 0.79-1.0). Among ncRCC subtypes, acquired cystic RCC demonstrated the highest association with end-stage renal failure and hypertension, with the highest CSS. MiT family translocation RCC had the youngest mean age at presentation (45.6±12.8 y) and excellent CSS. Factors associated with increased OS in the entire cohort included shorter operative time, partial nephrectomy and lower tumor stages.

This study provides a comprehensive contemporary overview of ncRCCs which are yet poorly characterized, in comparison to cRCCs. Data from this study would contribute towards tailored patient counseling and healthcare resource planning.
