Retrospective study of 107 patients diagnosed with infiltrant tumour of the bladder in stage T3-T4 N0-N1, treated with radical surgery. Eighty-four (84) received neoadjuvant therapy with radio- and/or chemotherapy. The neoadjuvant treatment was seen to provide significantly better survival, but the specific type of neoadjuvant treatment appears to have no influence. The multivariate study evidenced that the two most influential variables for survival are the complementary treatment and the clinical stage.

A prospective study which analyzes the presence of mutations in the suppressor oncogene p53 through automated genome sequentiation in 75 specimens of transitional cell carcinoma. The presence of mutations correlated to the pathological stage and cellular grade. Also, both the different types of mutations detected and the diversity of their location indicate the heterogeneity of bladder transitional cells carcinoma. The automated genome sequentiation method allows to detect both the type of mutation and the exact location. The detection of suppressor oncogene p53 mutations allows to identify those patients who may be at higher risk of disease progression and therefore those who should undergo a more intense follow-up.

Secondary or metastatic vesical tumours are a very uncommon condition (less than 1% of vesical tumours). Dissemination routes are usually through blood and lymph, and diagnosis occurs typically in advanced stages. This paper presents one case of metastatic vesical neoplasia that developed 5 years after diagnosis of the primary lung tumour.
