MOYANO CALVO, J.L. et al. Bladder wall's lymphatic vessels invasion in superficial bladder cancer: Prognostic value. Actas Urol Esp [online]. 2003, vol.27, n.4, pp.260-264. ISSN 0210-4806.

INTRODUCTION: It is not usual to use as prognostic factor the bladder lymphatic vessels invasion. METHOD & MATERIAL: 519 T1 bladder tumors with complete resection and follow up of one year at least. Prophylaxis with 81 mg of BCG weekly during six weeks in 54%. RESULTS: Follow up without recurrence of 38 months. 49%. Tumour recurrence of 49% and progression of 7%. 5,8% of the tumours are L1 and 70,7% L0. There are significative statistic relation between lympatic invasion and progression (p.005), tumoral grade (p.000) and actual situation (p.02). 23% of the L1 tumours progressed vs 5% of L0. Prophylaxis with BCG reduces progression risk (33% without treatment vs 16 with BCG (p n.s.)). In multivariate analysis, resected volume (p.024) and prophylactic treatment are independent variables for recurrence and lymphatic vessels invasion (p.0478) and tumoral grade (p.092) for progression. CONCLUSIONS: 1) L1 tumours has more probabilities of progression. 2) BCG disminishs progression rate but this is not statistical significative. 3) We ned new markers to select which L1 tumours will progress.
