Primary invasive versus progressive invasive transitional cell bladder cancer: multicentric study of overall survival rate.

INTRODUCTION AND OBJECTIVE: When feasible, the treatment for all-invasive bladder cancer is radical cystectomy. The aim of the present study was to analyze the prognostic difference, disease-specific survival rate, of muscle-invasive transitional cell cancer of the bladder (TCCB) for progressive invasive TCCB. PATIENTS AND METHODS: A retrospective multicentric analysis was performed studying a total of 242 patients who underwent radical cystectomy for invasive TCCB from 1993 to 2005. The patients were divided into two groups: group 1 included 57 patients with progressive invasive TCCB, and group 2 included 185 patients with primary invasive TCCB. Both groups were further divided according to the pathological findings in pT2/3 (muscle and/or perivesical fat invasion), pT4 (adjacent organs/structure invasion), N+ (positive lymphatic nodes) and M+ (distant organ metastasis). Several tests were employed for statistical analysis: chi2, Mann-Whitney, Kaplan-Meier method and Wilcoxon (Breslow) method were used to compare the possible survival curve differences of groups 1 and 2. Multivariated analysis determined by proportional risk regression excluded sex, age and disease stage interferences in the final results. RESULTS: The average time for a superficial TCCB to become muscle-invasive was 37.4 months, and the average number of transurethral resections performed in each patient was 3. The average and median global survival rates were, respectively, 96 and 88 months in group 1 and 98 and 90 months in group 2, without a statistically significant difference (p = 0.0734). The 1-year survival rate was 84.32% in group 1 and 76.54% in group 2. After 3 years of follow-up the survival rate fell to 74.50% in group 1 and to 59.05% in group 2. Finally, the 5-year survival rate was 57.94% in group 1 and 52.24% in group 2. CONCLUSION: In the present study, patients with primary invasive and progressive invasive TCCB showed a similar 5-year disease-specific survival rate. Pathological stage (pTN, N and M) and patient demography did not interfere with the results.

Testicular metastasis 10 years after resection of appendiceal carcinoid.

Testicular carcinoids are very rare and account for less than 1% of all testicular neoplasms. They may present as primary testicular tumors or secondary tumors from extratesticular sources. We report a case of a secondary testicular carcinoid occurring 10 years after surgical treatment of an appendiceal carcinoid. The patient underwent radical orchiectomy and at 24 months of follow-up had no evidence of metastases elsewhere. Because secondary carcinoids have a worse clinical course and prognosis than primary tumors, metastatic disease should be excluded before the tumor is identified as a primary. Long-term follow-up is necessary for patients with carcinoid tumor owing to its indolent course and the risk of metastasis several years after treatment of the primary.
