ABSTRACT

OBJECTIVES: To evaluate the cancer detection rate (CDR) of an early repeated flexible ureteroscopy (2nd-look-URS) and its impact on the conservative management of patients affected with upper urinary tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: Clinical and surgical data from 41 patients with UTUC who underwent 2nd-look-URS within 60 days of their first URS with concomitant laser tumour photoablation at a single tertiary care referral centre from 2009 to 2013 were retrospectively analyzed. Radical nephroureterectomy was offered during follow-up in case of massive tumour recurrence (defined as a tumour not completely removable only with a conservative approach). Descriptive statistics tested the impact of 2nd-look-URS outcomes on subsequent endoscopic evaluation. Kaplan-Meier curves assessed massive tumour recurrence-free survival (mRFS) rates according to the presence of a tumour at 2nd-look-URS. Cox regression analyses identified predictors of mRFS. RESULTS: CDR at 2nd-look-URS was 51.2 %. CDRs at third URS were 81.3 and 41.2 % in patients with a positive and a negative 2nd-look-URS, respectively (p = 0.02). At a mean (median) follow-up of 34.6 (27.6) months, mRFS rates were 88 and 48 % in patients with negative and positive 2nd-look-URS, respectively (log rank = 0.015). Tumour grade at first URS and 2nd-look-URS outcomes achieved predictor status for mRFS (HR 6.1, 95 % CI 1.42-26.27 and HR 5.39, 95 % CI 1.18-24.66, respectively, all p ≤ 0.03). CONCLUSIONS: 2nd-look-URS-related CDR in conservatively treated UTUC patients was 51.2 %. 2nd-look-URS outcomes affected the findings of both subsequent endoscopic evaluation and mRFS. Further studies are needed to confirm the benefits of this approach in terms of patient outcomes. More... »

    "description": "OBJECTIVES: To evaluate the cancer detection rate (CDR) of an early repeated flexible ureteroscopy (2nd-look-URS) and its impact on the conservative management of patients affected with upper urinary tract urothelial carcinoma (UTUC).\nMATERIALS AND METHODS: Clinical and surgical data from 41 patients with UTUC who underwent 2nd-look-URS within 60\u00a0days of their first URS with concomitant laser tumour photoablation at a single tertiary care referral centre from 2009 to 2013 were retrospectively analyzed. Radical nephroureterectomy was offered during follow-up in case of massive tumour recurrence (defined as a tumour not completely removable only with a conservative approach). Descriptive statistics tested the impact of 2nd-look-URS outcomes on subsequent endoscopic evaluation. Kaplan-Meier curves assessed massive tumour recurrence-free survival (mRFS) rates according to the presence of a tumour at 2nd-look-URS. Cox regression analyses identified predictors of mRFS.\nRESULTS: CDR at 2nd-look-URS was 51.2\u00a0%. CDRs at third URS were 81.3 and 41.2\u00a0% in patients with a positive and a negative 2nd-look-URS, respectively (p\u00a0=\u00a00.02). At a mean (median) follow-up of 34.6 (27.6) months, mRFS rates were 88 and 48\u00a0% in patients with negative and positive 2nd-look-URS, respectively (log rank\u00a0=\u00a00.015). Tumour grade at first URS and 2nd-look-URS outcomes achieved predictor status for mRFS (HR 6.1, 95\u00a0% CI 1.42-26.27 and HR 5.39, 95\u00a0% CI 1.18-24.66, respectively, all p\u00a0\u2264\u00a00.03).\nCONCLUSIONS: 2nd-look-URS-related CDR in conservatively treated UTUC patients was 51.2\u00a0%. 2nd-look-URS outcomes affected the findings of both subsequent endoscopic evaluation and mRFS. Further studies are needed to confirm the benefits of this approach in terms of patient outcomes.",
