[Infiltrating bladder carcinoma: influence of complementary treatment on local control and survival]. / Carcinoma vesical infiltrante: influencia del tratamiento complementario en el control local y en la supervivencia.

We analyzed 82 patients with transitional bladder cancer stages (T2-T4) M0. According to treatment, 3 different groups were considered: Group 1: 25 patients treated with TUR and radical cystectomy. Group 2: 33 patients also received external beam radiotherapy (45-60 Gy/5 weeks) prior cystectomy. Group 3: 24 patients were also treated with intraoperative radiotherapy (15 Gy) and 3 courses of neoadjuvant chemotherapy. Our results suggest that local control rate increases significantly with the intensity of treatment (Group 3: 62% patients were PT0). Similar results were achieved in multivariate analysis. Univariate analysis of survival shows ganglionar status, vascular embolism and treatment intensity as covariates associated. Multivariate analysis demonstrate that renal function and type of complementary treatment were the covariates associated with survival. Taking both groups 2 and 3, survival was related to pathologic stage, vascular embolism and renal function. In conclusion, the significant influence of complementary treatment on the local control and survival suggest strongly their systematic utilization in infiltrating bladder cancer.

[Effect of complementary treatment (radiotherapy, chemotherapy) on the survival of patients with T3 tumors of the bladder treated with radical surgery]. / Influencia del tratamiento complementario (radioterapia, quimioterapia) en la supervivencia de los tumores de vejiga T3 sometidos a cirugía radical.

We present the results obtained from the study of 65 patients with vesical carcinoma stage T3 treated with radical surgery with or without supplementary radiotherapy, with or without supplementary chemotherapy. The multivaried study of survival (Cox's model) shows that it depends significantly on the surgical complications and on the pathological state at the time of the cystectomy. Univaried analysis indicates that patients with descent from post-radiotherapy stage and those subjected to IOR (intraoperative radiotherapy) have a significantly better survival than the rest and suggests that radiotherapy improves overall survival. Influence of supplementary treatment (radiotherapy, chemotherapy) in the survival of T3 bladder tumours subjected to radical surgery.
