Decisional Conflict is Associated with Treatment Modality and not Disease Knowledge in South African Men with Prostate Cancer: Baseline Results from a Longitudinal Prospective Observational Study.

BACKGROUND: Decisional conflict (DC) is a psychological construct that an individual experiences in making a decision that involves risk, loss, regret, or challenges to one's values. This study assessed DC in a cohort of South African men undergoing curative treatment for localised prostate cancer (LPC). The objectives were to (1) to examine the association between DC and prostate cancer knowledge (PCK), demographics, state anxiety, prostate cancer anxiety and time to treatment and (2) to compare levels of DC between treatment groups [prostatectomy (RP) and external beam radiation (RT)]. METHOD: Data, comprising the Decisional Conflict Scale (DCS), Prostate Cancer Knowledge (PCK), State-Trait Anxiety Inventory (STAI-S), the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) and demographic data from 83 participants of a larger prospective longitudinal observational study examining depression, anxiety and health related quality of life (DAHCaP) were analysed. RESULTS: The mean age of participants was 63 years (RP 61yrs and RT 65yrs; p< 0.001). Most were of mixed ancestry (72.3%). The total DCS scores between the treatment groups (RP 25.00 and RT 18.75; p = 0.037) and two DCS sub-scores-uncertainty (p = 0.033), and support (p = 0.048), were significantly higher in the RP group. A statistically significant negative correlation was observed between state anxiety and time between diagnosis and treatment in the RP group (Spearman's rho = -0.368; p = 0.030). There was no correlation between the DCS score and PCK within each treatment group (Spearman's rho RP = -0.249 and RT = -0.001). CONCLUSION: Decisional conflict was higher in men undergoing RP. Men were more anxious in the RP group regarding the time treatment was received from diagnosis. No correlation was observed between DC and PCK. Pre-surgical management of DC should include shared decision making (SDM) which is cognisant of patients' values facilitated by a customised decision aid.

The pathologist's role in the detection of rare variants of bladder cancer and analysis of the impact on incidence and type detection.

BACKGROUND: Histology is one of the most important factors determining the prognosis of bladder cancers and rare variants are generally associated with decreased disease specific survival compared to pure transitional cell carcinomas. We believe that rare bladder cancer variants are likely underdiagnosed in the absence of a dedicated uro-pathologist in many centers. The objective of this study is to evaluate the contribution of a dedicated uro-pathologist on the identification of rare bladder cancer variants. METHODS: We retrospectively analyzed the clinical and histological records of all patients which underwent a radical cystectomy and lymph node dissection between January 2000 and September 2015. The sample was divided in two groups: Group A, consists of patients who underwent radical cystectomy in the absence of a dedicated uro-pathologist at our institution, whereas the Group B consists of patients who underwent surgery when a dedicated uro-pathology service was available. We then evaluated the impact of a dedicated uro-pathologist on rare variants detection. RESULTS: One hundred thirty-seven out of 551 (24.9%) of patients who underwent RC had at least one rare variant. In Group A 38/238 (16%) of patients showed a rare variant, while 99/313 (31.6%; P<0.001) in group B. Furthermore, the diagnosis of sarcomatoid variant was statistically significantly less common in group A (P=0.0026). The concordance between final radical cystectomy histology and previous transurethral resection of bladder tumor (TURBT) histology was poor in both groups (overall 50.4%). CONCLUSIONS: The presence of a dedicated urological anatomical pathologist is of paramount importance and significantly increases the detection rate of non-transitional cell carcinoma bladder cancer types, but it does not increase the concordance rate between histological diagnoses in TURBT and radical cystectomy specimens.
