To investigate the current status and feasibility of robotic neobladder diversion after robotic assisted radical cystectomy. A Medline search was conducted resulting in identification of 423 articles. After exclusion of ineligible studies, 3 case series and 5 case reports were considered with a total number of reported cases of 203. Although robotic intracorporeal neobladder reconstruction is in its starting phase, initial perioperative results seem to be comparable to open series. However, randomized studies are needed to confirm non-inferiority.

Previous studies showed that the frequency of beta-catenin mutation was different in mice when induced by different chemicals. The aim of this study is to compare the expression of beta-catenin and p53 in hepatocellular carcinoma (HCC) from areas with exposure to high and low levels of aflatoxin B1 (AFB1).

Metastatic breast cancer is an incurable disease. With improvement in systemic therapy, survival has improved over the past few years. Removing the primary tumor has shown improved survival in retrospective studies, but this may be due to selection bias. The first reported randomized controlled trial (RCT) from India showed no difference in survival with surgery. However another RCT from Turkey showed that a select group of patient with bone-only metastases have a survival benefit.

BACKGROUND AND OBJECTIVES: Triple negative breast cancer (TNBC) carries a worse prognosis compared to the other subtypes. There have been conflicting studies that race may impact the prognosis of TNBC patients. We aim to determine the incidence and prognosis of TNBC among the different ethnic races in Singapore, and to determine its associated risk factors for prognosis.

METHODS: Patients diagnosed with invasive breast cancer (BC) from 2005 to 2013 at our tertiary institution were included and divided according to race and subtypes. Demographic and clinical information of non-metastatic TNBC patients were analyzed. Log-rank test, univariate and multivariate Cox proportional hazard regression models were used to find associated risk factors related with overall survival (OS) and disease-free survival (DFS).

RESULTS: Among 1227 BC patients, 129 (10.5%) had TNBC. TNBC patients had the worst OS (P: 0.0005) and DFS (P: 0.0016) among the subtypes. However, variations in race did not have any difference in OS or DFS among TNBC patients. Axillary lymph node involvement, invasive lobular histology, larger tumor size, and the presence of lymphovascular invasion (LVI) were factors associated with both poor DFS and OS among TNBC patients.

CONCLUSIONS: Racial variation did not have any impact on the prognosis of the TNBC.
