Risk of continued intravesical therapy and delayed cystectomy in BCG-refractory superficial bladder cancer: an investigational approach.

OBJECTIVES: To assess the risk of continued intravesical therapy and delayed cystectomy in the management of superficial bladder cancer refractory to bacillus Calmette-Guérin (BCG) therapy. METHODS: We retrospectively reviewed the medical records of 24 patients who underwent an experimental intravesical treatment with BCG plus interferon alpha-2b or valrubicin for transitional cell carcinoma of the bladder. All patients had Stage Tis and/or T1 transitional cell carcinoma and had failed multiple prior courses of intravesical therapy, including at least one course of BCG. RESULTS: Patients were followed up for a median of 28.5 months (range 6 to 48). One patient died of unrelated disease. All other patients were alive at last follow-up. Fourteen patients with preserved bladder were continuing cystoscopic surveillance: four had no recurrence, five had recurrence limited to the mucosa (Ta or Tis) and became free of disease after an additional course of intravesical therapy, and five had recurrent Ta or Tis or positive cytologic findings. The remaining 9 patients underwent radical cystectomy. All pathologic specimens showed no evidence of progression to muscle-invasive disease. Tis of the resected ureters in 6 and involvement of the prostate in 4 of the 9 patients (three in the urethral ducts and glands and one in the prostatic stroma) were noted. CONCLUSIONS: A select group of patients with BCG-refractory transitional cell carcinoma and a poor surgical risk for cystectomy may benefit from continued intravesical therapy without a significant risk of progression. However, a cautious approach to this treatment modality is recommended, and very close follow-up is necessary to detect bladder recurrences and involvement of the upper tract and prostatic urethra.

Second opinion of anatomical pathology: a complex issue not easily reduced to matters of right and wrong.

PURPOSE: We discuss the subject of a second opinion for interpretations of anatomical pathology from the perspective of patient care. MATERIALS AND METHODS: We grouped 150 cases involving pathological review at our institution into 3 categories depending on the effect on patient care. RESULTS: Of 29 interpretive discrepancies 14 resulted in treatment changes but 7 of these 14 may have been interpreted differently by other practice groups. CONCLUSIONS: Whether the second opinion represents an interpretive error or a legitimate difference of opinion, the result may affect patient care. Patients referred for treatment among practice groups should have pathological findings reviewed as part of a complete assessment by the new physicians.

Incidental renal cell carcinoma-age and stage characterization and clinical implications: study of 1092 patients (1982-1997).

OBJECTIVES: To compare the epidemiologic, clinical, and pathologic characteristics of incidental and symptomatic renal cell carcinoma in a large series of patients, with emphasis on age distribution and its potential impact in defining groups of patients that may benefit from early detection programs. METHODS: Records of 1092 patients with renal tumors from 1982 to 1997 were reviewed. Age, clinical presentation, and pathologic stage and grade were analyzed. Special attention was given to the age distribution and its relationship to the incidental or symptomatic diagnosis. RESULTS: The overall mean age and proportion of patients older than 65 gradually increased (from 57 to 62.6 years and from 24.7% to 48.7%, respectively) from 1982 to 1997. The mean age in the incidental group rose steadily higher than in the symptomatic group. A progressive increase of incidental tumors from 13.0% in 1982 to 1983 to 59.2% in 1996 to 1997 was observed. A lower stage (74.3% versus 49.1%), grade (75.5% versus 56.9%), and percentage of metastases at presentation (10.4% versus 19.6%) were registered in the incidentally found neoplasms than in the symptomatic neoplasms. Eighty-two (80.4%) of 102 patients who underwent conservative surgery had incidental renal cell carcinoma. CONCLUSIONS: Our data confirm a rapid and dramatic change in the epidemiologic and clinical characteristics of renal cancer, with an increasing number of incidentally found tumors presenting with lower stage, grade, and percentage of metastases. An unexpected but significantly higher rate of renal neoplasms was observed in older patients. The stage, grade, and patient age observed in our series of incidentally found tumors raises the question of whether to leave the current diagnostic approach unaltered, thus benefiting a subgroup of patients with clinically unrecognized and possibly indolent renal cell carcinoma, or to extend early detection programs to younger patients with potentially more aggressive tumors.

[Endoscopic treatment of bladder diverticula].

Since February 1993 six patients with bladder diverticula have undergone resection of the diverticular neck and fulguration of the diverticular mucosa at the time of transurethral resection of the prostate in 5 cases and urethral dilation in one case. The mean dimension of the diverticular was 5.2 cm. After a mean follow-up of 20 months the diverticulum has largely shrunk in one case and has completely disappeared in 5 cases. Our paper demonstrates the effectiveness of this technique in the treatment of bladder diverticular. In our opinion endoscopic fulguration represents a valid alternative to open surgery for the treatment of small bladder diverticular.
