The Risk Of Persistent Local Disease In Bladder Cancer Patients Found To Be Pathologic Stage T0 At Radical Cystectomy
While post-chemotherapy staging of the bladder is known, the risk of involvement of the pelvic lymph nodes (LNs) in these patients is less well documented. The authors sought to evaluate the status of the regional LNs in patients that have achieved pT0 status. Therefore, the authors evaluated the pathologic characteristics of patients with Tis-T4 disease on transurethral resection of the bladder tumor, but were pT0 at the time of radical cystectomy. They evaluated the LN status at time of radical cystectomy.
Out of 1,925 patients undergoing a RC between 1990 and 2008, 51 had received chemotherapy prior to RC and were pT0 at the time of surgery. The median LN count was 12 (range 1-51). None of the 33 patients receiving neoadjuvant chemotherapy and 33% of the 21 patients who had received chemotherapy prior to cystectomy for metastatic or locally advanced disease had lymph node metastases at the time of surgery.
The authors concluded that the regional LNs in the pT0 population remain a potential site of active disease in patients who received chemotherapy for locally advanced bladder cancer. The risk of LN metastases in patients who receive neoadjuvant chemotherapy for cT3 or less disease and are pT0 at time of surgery is very low.
