[Partial cystectomy as treatment of infiltrating transitional carcinoma of the bladder].

UNLABELLED

The most widespread opinion, and until recently the only option, is that every vesical transitional cancer invading the muscle is, regardless its extent, candidate for radical cystectomy and that in spite of nobody questioning the advantages of partial cystectomy.

MATERIAL AND METHODS

45 patients with vesical infiltrant cancer T2 or higher, followed between 9 and 258 months and managed with partial cystectomy, were analyzed. Only patients with no radiotherapy were included and only in one patient pre-operative chemotherapy was used.

RESULTS

In 8 patients no tumour was found in the specimen (pTO). Tumour grade was pTa in 2; pT1 in 11; pT2 in 5; pT3a in 4; pT3b in 11; and pX in 4 patients. Eight (8) patients had nodal involvement. Twenty-one (21) cases showed bladder relapse. In six (6), vesical infiltrant relapse was associated to metastasis. One case showed vesical relapse, pelvic mass and metastasis, and 4 only metastasis. Extravesical disease-free time and survival are better than in the group treated with radical cystectomy. But this is a highly selected group.

CONCLUSIONS

With the same prospects of extravesical disease-free time and survival we offer: shorter, less risky surgery with low post-surgical morbidity and mortality and less hospitalization and proportion of late sequela. Better quality of life, with no skin stoma, incontinence or impotence Although the risk of vesical relapse persists, the procedures required to resolve vesical shunt or replacement complications are more aggressive than TUR sufficient to treat most relapses, and when recurrence is infiltrant radical cystectomy may be used as a rescue measure. This is so even now with the profusion of the so-called "mini-invasive" procedures. We believe that neither radio- and/or chemotherapy combinations contribute nothing to partial cystectomy alone. They may even be harmful and have significant side-effects. It is plain that POs are the result of total removal by TUR. Due to the little reliability when defining T, it is very hard to evaluate the contribution of adjuvant measures. Patients with no vesical tumour (pTOs) or pT1-pT2 tumours, and even up to pT3a, should not be included in protocols to evaluate the efficacy of combined cytostatic agents since their use is superfluous. Radiotherapy makes no contribution to this type of tumour in terms of local relapse and apparently has no effect on the metastasis.
