Background: The Bacillus Calmette-Guerin (BCG) vaccine has long been used for the prevention of tuberculosis (TB) around the world. BCG is also used as an immunotherapy agent for the treatment of non-muscle invasive urinary bladder cancer. This scoping literature review and preliminary data analysis aims to summarize the literature correlating infantile BCG vaccination with the incidence of future bladder cancer. Methods: Studies were identified by a formal literature search of MEDLINE and Cochrane Central Registrar of Controlled Trials following PRISMA guidelines. Preliminary data analysis was conducted on publicly accessible data summarizing the impact of gender, BCG vaccination, and socio-economic effects on crude and age-standardized rates of bladder cancer. Results: As part of our analysis, preliminary regression models demonstrated BCG vaccination status, gender, and socio-economic status to have statistically significant effects on crude and age-standardized rates of bladder cancer incidence. BCG vaccination was associated with a 35-37% lower age-standardized rate of bladder cancer incidence. Conclusions: There is very little literature examining the relationship between prior BCG vaccination and rates of bladder cancer incidence. Our limited data analysis indicates that a relationship does exist between infantile BCG vaccination and later bladder cancer development, although extensive future investigation is needed in this area.
Introduction: Guidelines surrounding the management of T4b muscle-invasive bladder cancer (MIBC) with radical cystectomy (RC) are limited and lack clarity. Our objective was to analyze our single-center experience to provide additional insight into the role of RC. Methods: We performed a retrospective data analysis using clinical, radiological, and pathological information for all patients managed by RC for cT4b MIBC at the Thunder Bay Regional Health Sciences Centre (July 2015 to July 2020). Patients that had MIBC as their first diagnosis were termed the de novo group and patients that were initially diagnosed as having non-MIBC were termed the progressive group. Results: Nineteen consecutive patients (16 males and three females), with a median age of 68, managed by two urologists over the last five years, met study criteria. Eleven (58%) of the patients had de novo MIBC while eight (42%) presented with progressive disease. All patients had dysuria as a presenting symptom. Only one (5%) patient received neoadjuvant chemotherapy. There were low rates of perioperative transfusion (11%), bowel resections (5%), postoperative transfusions (0%), ileus (32%), urine leak (16%), and wound dehiscence (5%). Fourteen (74%) had positive lymph nodes. All patients had adjuvant chemotherapy. The one-year recurrence rate in these patients was 53%, with 32% of recurrence being distant metastasis. The one-year survival rate was 95%. Conclusions: Patients in the de novo and progressive arms of our cohort had similar rates of surgical complications and disease recurrence. We found operative morbidity and disease control to be reasonable, suggesting RC can be considered more often in the management of T4b MIBC patients.
Spontaneous retroperitoneal hemorrhage (SRH) is a rare emergency. It is usually encountered in patients on hemodialysis and is associated with high rate of morbidity and mortality. This is a case from the emergency department. The patient had unstable vitals with SRH following dialysis. Immediate exploration and nephrectomy using transverse lateral lumbotomy incision were done. Patients on hemodialysis are at a risk of SRH and frequent surveillance is recommended. Acquired cystic kidney disease (ACKD) can develop in hemodialysis patients and put them at risk for bleeding. Transverse lateral lumbotomy may be a safe option for direct access to the kidney in emergency kidney surgery.
The majority of patients with renal cell carcinoma develop recurrence within 5 years following radical nephrectomy. Very late sole local recurrence beyond 10 years is rare, and all reported cases had clear cell histology. Surgical resection of local recurrence remains the best option for disease management. This case opens the way for further studying the rare histological variants of renal cancer and to encourage prolonged follow-up and offering surgery as the best option for managing these cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
