BACKGROUND: Previous studies found a range of prognostic factors but no consensus about the proper staging system for @entity1582 has been achieved. This study explored the prognostic factors to find a staging system for @entity1582 most suitable for Chinese @entity1 . METHODS: Between February 1990 to August 2004, 206 @entity1 (138 @entity1 and 68 @entity1 , mean aged (59 +/- 11) years) who were initially diagnosed as @entity1582 in Changzheng Hospital (Shanghai, China) and had followup records were enrolled in this study. Potential prognostic factors were evaluated by univariate and multivariate analyses. Four staging systems were applied to compare their suitability for the @entity1 . RESULTS: The median survival time of the @entity1 was 33 months. The 1-, 3- and 5-year survival rates were 80.18%, 48.08% and 33.7% respectively. Factors identified as adversely affecting survival were older age, severe @entity79 , low haemoglobin, low platelet, low serum @entity460 , low serum albumin, high proportion of plasma cells in marrow, high serum @entity1011 , high serum @entity2262 and high @entity1851 . Among these, only @entity1851 , @entity2262 , albumin and age were the independent prognostic factors. There were statistically significant survival differences among the three groups in Durie Salmon staging system and Bataille staging system, but not in British Medical Research Council staging system or International Staging System. CONCLUSIONS: High @entity2262 , high @entity1851 , low albumin and old age are independent prognostic factors of @entity1582 . Bataille staging system appears to be optimal for Chinese @entity1582 @entity1 .
