Aspirin use is associated with lower prostate cancer risk in male carriers of BRCA mutations.

Previous studies have shown that male BRCA mutation carriers stand at increased risk of developing prostate cancer and have concerns about developing cancer. Genetic counseling practitioners often discuss strategies for reducing the risk of cancer for patients at high risk due to their genetic background. Addressing modifiable health habits is one such strategy. Unfortunately, modifiable risk factors for prostate cancer have only been documented in the general population and have not yet been studied in the BRCA carrier subpopulation. Therefore, this study aimed to identify modifiable risk factors for prostate cancer in BRCA carriers. We examined prostate cancer risk factors in 74 men who were part of families with a BRCA mutation. This study examined nine dichotomous variables including: exercise, history of vasectomy, smoking history, alcohol use, finasteride use, statin use, aspirin use, coffee use, and vitamin use. The survey was sent to all cases of prostate cancer in the Hereditary Cancer Center Database at Creighton University with a known BRCA status. This study confirmed the protective benefits of daily aspirin use, which have been observed in previous studies of the general population, and suggests its benefit in BRCA carriers. Protective benefits from regular vigorous exercise and daily coffee use trended towards significance, but neither factor withstood the Bonferroni Correction for multiple comparisons.

A practical approach to difficult urinary catheterizations.

Routine placement of transurethral catheters can be challenging in some situations, such as urethral strictures, severe phimosis and false passages. Intravaginal retraction of the urethral meatus can complicate Foley placement in postmenopausal females. In men, blind urethral procedures with mechanical or metal sounds without visual guidance or guidewire assistance are now discouraged due to the increased risk of urethral trauma and false passages. Newer techniques of urethral catheterization including guidewires, directed hydrophilic mechanical dilators, urethral balloon dilation, and direct vision endoscopic catheter systems are discussed, along with the new standardized protocol for difficult transurethral catheter insertions. Suprapubic catheter placement techniques, including percutaneous trocars and the use of the curved Lowsley tractor for initial suprapubic catheter insertion, are reviewed. Prevention and management of common catheter-related problems such as encrustation, leakage, Foley malposition, balloon cuffing and frequent blockages are discussed.

Survival differences among patients with bladder cancer according to sex: Critical evaluation of radical cystectomy use and delay to treatment.

OBJECTIVE: Sex differences in bladder cancer survival are well known. However, the effect of type of treatment, timing to surgery when rendered, and survival outcomes according to sex have not been extensively examined. Given the relatively low incidence of bladder cancer in females, large multicenter and population-based studies are required to elucidate sex differences in survival. In this study, we sought to characterize the effect of use and timing of radical cystectomy (RC) according to sex and survival outcomes. METHODS: A total of 9,907 patients aged 66 years or older diagnosed with clinical stage II to IV N0M0 bladder cancer from January 1, 2001 to December 31, 2011 from Surveillance, Epidemiology, and End Results-Medicare data were analyzed. We used multivariable regression analyses to identify factors predicting the use and delay of RC. Cox proportional hazards models were used to analyze survival outcomes. RESULTS: Of the 9,907 patients diagnosed with bladder cancer, 3,256 (32.9%) were females. Women were significantly more likely to undergo RC across all stages compared to their male counterparts (stage II: relative risk [RR] = 1.48, 95% CI: 1.33-1.65, P<0.001; stage III: RR = 1.24, 95% CI: 1.13-1.37, P<0.001; and stage IV: RR = 1.33, 95% CI: 1.19-1.49, P<0.001). Moreover, there was no significant difference in delay to RC according to sex across all clinical stages. Using propensity score matching, women had worse overall (hazard ratio = 1.07; CI: 1.01-1.14; P = 0.024), and worse cancer-specific survival (hazard ratio = 1.26; CI: 1.17-1.36, P<0.001) than men. CONCLUSION: Sex differences persist with women who are significantly more likely to undergo RC independent of clinical stage. However, women have significantly worse survival than men. Delay from diagnosis to surgery did not account for this decreased survival among women.

Synchronous Renal Cell Carcinoma and Gastrointestinal Malignancies.

While renal cell carcinoma is the most commonly diagnosed neoplasm of the kidney, its simultaneous diagnosis with a gastrointestinal malignancy is a rare, but well reported phenomenon. This discussion focuses on three independent cases in which each patient was diagnosed with renal cell carcinoma and a unique synchronous gastrointestinal malignancy. Case 1 explores the diagnosis and surgical intervention of a 66-year-old male patient synchronously diagnosed with clear cell renal cell carcinoma and a carcinoid tumor of the small bowel. Case 2 describes the diagnosis and surgical intervention of a 61-year-old male found to have clear cell renal cell carcinoma and a mucinous appendiceal neoplasm. Lastly, Case 3 focuses on the interventions and management of a 36-year-old female diagnosed with synchronous clear cell renal carcinoma and hereditary nonpolyposis colorectal cancer. This case series examines each distinct patient's presentation, discusses the diagnosis, and compares and contrasts the findings while discussing the literature on this topic.
