ABSTRACT
BACKGROUND: GLOBOCAN12 recently reported high cancer mortality in Malaysia suggesting its cancer health services are under-performing. Cancer survival is a key index of the overall effectiveness of health services in the management of patients. This report focuses on Subang Jaya Medical Centre (SJMC) care performance as measured by patient survival outcome for up to 5 years. MATERIALS AND METHODS: All women with breast cancer treated at SJMC between 2008 and 2012 were enrolled for this observational cohort study. Mortality outcome was ascertained through record linkage with national death register, linkage with hospital registration system and finally through direct contact by phone or home visits. RESULTS: A total of 675 patients treated between 2008 and 2012 were included in the present survival analysis, 65% with early breast cancer, 20% with locally advanced breast cancer (LABC) and 4% with metastatic breast cancer (MBC). The overall relative survival (RS) at 5 years was 88%. RS for stage I was 100% and for stage II, III and IV disease was 95%, 69% and 36% respectively. CONCLUSIONS: SJMC is among the first hospitals in Malaysia to embark on routine measurement of the performance of its cancer care services and its results are comparable to any leading centers in developed countries.

OBJECTIVE: Asia is predicted to have the largest population of patients with diabetes who are at high risk for renal disease. In the Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) study, approximately 17% of patients were Asians. In this subgroup analysis, we examined the characteristics, response, and adherence to treatment of the Asian population, as well as their baseline predictors of risk of renal end points. RESEARCH DESIGN AND METHODS: A total of 252 Asian patients were enrolled in the RENAAL study, which compared losartan (50 mg titrated to 100 mg) to placebo in addition to conventional antihypertensive medications in type 2 diabetic patients with nephropathy. Mean follow-up was 3.2 years. The effect of losartan therapy on renal and cardiovascular outcomes was examined, and baseline predictors of risk were determined using a Cox proportional hazards model with prespecified baseline covariates. RESULTS: Losartan reduced the risk of the primary composite end point composed of a doubling of serum creatinine, end-stage renal disease, or all-cause mortality in Asian patients by 35% (P = 0.02). No difference between losartan and placebo was observed for the cardiovascular composite outcomes. Losartan reduced the level of proteinuria by 47% (P < 0.001) and rate of decrease in renal function by 31% (0.0074). Discontinuations were lower in the losartan-treated patients. The strongest baseline predictors of risk of renal end points were proteinuria (hazard ratio 1.42, P < 0.0001) and low Hb (0.81, P < 0.0001). CONCLUSIONS: In this subgroup analysis of the RENAAL study, losartan conferred significant renal benefits and was well tolerated in Asian patients with type 2 diabetes and clinical nephropathy. Baseline proteinuria and low Hb were strong predictors of risk of renal outcomes.
