Background : Diagnostic and therapeutic importance of pelvic lymph node (LN) dissection (PLND) in radical cystectomy (RC) has gained recent attention. A method of pathological analysis of LN affects total number of LN removed, number of LN involved, and LN density. Objective : To compare extended lymphadenectomy to standard lymphadenectomy in terms of LN yield, density, and effect on survival. Materials and Methods : From Jan 2004 - July 2009, 78 patients underwent RC whose complete histopathological report was available for analysis. All were transitional cell carcinoma. From July 2007 onward extended LN dissection was started and LNs were sent in six packets. Twenty-eight patients of standard PLND kept in group I. Group II had 23 patients of standard PLND (LN sent in four packets), and group III had 23 patients of extended PLND (LN sent in six packets). SPSS 15 software used for statistical calculation. Results : Distribution of T-stage among three groups is not statistically significant. Median number of LN harvested were 5 (range, 1-25) in group I, 9 (range, 3-28) in group II, and 16 (range, 1-25) in group III. Although this is significant, we did not find significant difference in number of positive LN harvested. We did not find any patient with skip metastasis to common iliac LN in group 3. Conclusions : Separate package LN evaluation significantly increased the total number of LN harvested without increasing the number of positive LN and survival.
