“…Most prognostic studies of bladder cancer have dealt with survival (Osborn et al, 1982;England et al, 1981;Kishi et al, 1981;Cifuentes Delatte et al, 1982) and a minority with recurrence or metastasis (Dalesio et al, 1983;Pocock et al, 1982). Moreover these prognostic studies have generally been concerned with 'Western' bladder cancer (Osborn et al, 1982;Dalesio et al, 1983;Pocock et al, 1982) while few studies have dealt with bilharzial bladder cancer (Ghoneim et al, 1972(Ghoneim et al, ,1976(Ghoneim et al, ,1979Sherif and Ibrahim, 1983 England et al, 1981;Ghoneim et al, 1972Ghoneim et al, ,1976Smith & Whitmore, 1981;Varkarakis et al, 1975;Ballanger & Ballanger, 1982). Our study did not prove the prognostic value of multiplicity or histopathology of the tumour; some authors concur with this conclusion while others dissent (Ghoneim et al, 1979;Kishi et al, 1981).…”
