Li H, Zhou J, Chen R, Zhu J, Wang J, Wen R. The efficacy and timing of adjuvant chemotherapy in upper tract urothelial carcinoma. Urol Oncol 2023:S1078-1439(23)00143-6. [PMID: 37331821 DOI: 10.1016/j.urolonc.2023.04.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 04/02/2023] [Accepted: 04/16/2023] [Indexed: 06/20/2023]
Abstract
BACKGROUND A recovery period between surgery and initiation of adjuvant chemotherapy (AC) is common in patients with upper tract urothelial carcinoma (UTUC), which can progress after a relatively long time. Therefore, the efficacy of AC initiated within 90 days after radical nephroureterectomy (RNU) was evaluated in UTUC patients at stage ≥pT2 (N0-3M0), in addition to the effect of delayed AC initiation on survival outcomes. METHODS Clinical data for 428 UTUC patients diagnosed with transitional cell carcinoma with postoperatively confirmed pathological stages, muscle-invasive or greater-stage (pT2-4) disease, any nodal status, and metastasis-free (M0) disease were retrospectively analyzed. All patients who received AC were treated within 90 days after RNU and underwent at least 4 cycles of the AC procedure. Then, patients receiving AC were divided into the "within 45 days" and "45 to 90 days" groups according to the time interval between RNU and AC initiation. Their clinicopathological characteristics were evaluated and the survival outcomes of the 2 groups were compared. Any adverse events that occurred during the AC process were also recorded. RESULTS A total of 428 patients were analyzed in the study, including 132 individuals who underwent the AC procedure with platinum in combination with gemcitabine within 90 days after RNU and 296 patients who failed to initiate AC within 90 days. The median age of all patients was 68 years (mean 67, range 28-90 years), and the median follow-up was 25 months (mean 36, range 1-129 months). There were no significant differences in age, sex, lymph node metastasis, tumor location, hydronephrosis status, hematuria status, cancer grade, or multifocality between the 2 groups. Individuals undergoing AC initiated within 90 days of RNU showed a significantly decreased mortality relative to those patients who did not receive AC. Shorter intervals between RNU and AC initiation within 45 days vs. 45-90 days did not improve patient OS and cancer-specific survival (CSS) and may have increased the incidence of adverse events. CONCLUSION The present study data supported the finding that a platinum-based combination with gemcitabine regimen initiated postoperatively significantly improved OS and CSS in patients with UTUC at stages ≥pT2 (N0-3M0). Furthermore, no survival benefit was evident in patients who started AC within 45 days after RNU compared to those who received AC within 45 to 90 days.

Preoperative upper tract invasive diagnostic modalities are associated with intravesical recurrence following surgery for upper tract urothelial carcinoma: A population-based study. PLoS One 2023; 18:e0281304. [PMID: 36730353 PMCID: PMC9894449 DOI: 10.1371/journal.pone.0281304] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Accepted: 01/20/2023] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Intravesical recurrence (IVR) after surgery for upper tract urothelial carcinoma (UTUC) is a clinical problem. We investigated if preoperative invasive diagnostic modalities (IDM) such as antegrade/retrograde uretero-pyelography and/or selective urine cytology/barbotage, and URS with or without concomitant biopsy are associated with IVR after radical surgery for UTUC. Risk of death from urothelial cancer and all causes was investigated as secondary outcomes. METHODS We investigated a population-based cohort of 1038 consecutive patients subjected to radical surgery for UTUC 2015-2019 in Sweden, using the Bladder Cancer Data Base Sweden (BladderBaSe 2.0), comprising all patients in the Swedish National Registry of Urinary Bladder Cancer. Risk estimates of IVR, death from urothelial cancer, and all causes was assessed using multivariable Cox regression models. RESULTS The study included 536 cases with and 502 without preoperative IDM. IDM was associated with increased risk of IVR (HR 1.24, 95% CI 1.03-1.52) and risk of urothelial cancer death (HR 1.56, CI 1.12-2.18), compared to no IDM after a median follow-up of 1.3 yrs. Stratified analysis for tumor location showed that IDM was associated with risk of IVR in ureteric cancer (HR 1.66, 95% CI 1.21-2.28) but not in renal pelvic cancer (HR 1.07, 95% CI 0.81-1.41). Limitations included the observational setting and the lack of variables such as tumour grade, multifocality and preoperative hydronephrosis. CONCLUSIONS Worse outcomes for patients subjected to preoperative IDM highlight the need for carefully considering diagnostic decisions for UTUC patients, specifically in tumours located in the ureter.

The prognostic impact of lymph node dissection for clinically node-negative upper urinary tract urothelial carcinoma in patients who are treated with radical nephroureterectomy. PLoS One 2022; 17:e0278038. [PMID: 36454803 PMCID: PMC9714942 DOI: 10.1371/journal.pone.0278038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 11/08/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND To evaluate the prognostic impact of lymph node dissection (LND) in patients who underwent radical nephroureterectomy (RNU) with bladder cuff excision (BCE) for clinically node-negative (cN0) upper urinary tract urothelial carcinoma (UTUC). METHODS We retrospectively enrolled 520 patients with cN0 UTUC in a single tertiary referral center from 2000 to 2015. The patients were divided into three groups: patients with and without pathologically proved lymph node metastasis (pN1-3 and pN0, respectively) and patients without LND (pNx). We analyzed associations between overall survival (OS)/ disease-free survival (DFS)/ cancer-specific survival (CSS) and clinical characteristics. RESULTS The patients were divided into three groups (pN1-3, pN0 and pNx with 20, 303, and 197 patients, respectively). OS/DFS/CSS in the pN1-3 group were significantly worse (all p<0.001) compared with the pN0 group. However, there were no significant differences between the pNx and pN0 groups. In the multivariate analyses, CSS was only affected by age [(hazard ratio (HR) = 1.03, p = 0.008]), positive surgical margin (HR = 3.38, p<0.001) and pathological T3-4 stages (HR = 4.07, p<0.001). In the subgroup analyses for patients with LND, locally advanced disease (pT3 and pT4) had significantly more metastases [T3-4: 13.91% (16/115) vs. T0-2: 1.92% (4/208), p<0.001]. CONCLUSIONS In the pN0 group, LND for cN0 UTUC did not show therapeutic benefits in terms of DFS, CSS, and OS. However, LND with RNU allowed optimal tumor staging, through patients still had a poor prognosis. Clinically occult LN metastases were found in 6.2% of our patients.

Clinical Implication of Preoperative Renal Function on Oncological Outcomes in Patients with Upper Tract Urothelial Carcinoma after Radical Nephroureterectomy. Biomedicines 2022; 10:biomedicines10061340. [PMID: 35740362 PMCID: PMC9220201 DOI: 10.3390/biomedicines10061340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 05/15/2022] [Accepted: 05/30/2022] [Indexed: 11/29/2022] Open
Abstract
This study aims to evaluate the impact of preoperative renal function on oncological outcomes in patients with upper tract urothelial carcinoma (UTUC) who underwent radical nephroureterectomy (RNU). We performed a retrospective analysis of patients who underwent RNU between 2000 and 2012 at six academic centers. The patients were stratified into two groups based on preoperative renal function: eGFR < 60 mL/min/1.73 m2 (chronic kidney disease; CKD) and eGFR ≥ 60 mL/min/1.73 m2 (non-CKD). We investigated oncological outcomes, including overall survival, cancer-specific survival, and progression-free survival dichotomized by preoperative renal function. Multivariable Cox proportional hazards regression was used to determine if preoperative CKD was associated with oncological outcomes. In total, 1733 patients were eligible for the present study (CKD = 707 and non-CKD = 1026). Significant differences were noted in the clinical and pathologic features among the two groups, including age, sex, tumor localization, pathological T stage, tumor grade, and number of patients who received adjuvant chemotherapy. The estimated five-year overall survival (79.4 vs. 67.5%, log-rank p < 0.001), cancer-specific survival (83.5 vs. 73.6%, log-rank p < 0.001), and progression-free survival (74.6 vs. 61.5%, log-rank p < 0.001) were significantly different between the two groups, longer in the non-CKD group. Upon multivariable analysis, preoperative CKD status was associated with increased risk of overall mortality, cancer-specific mortality, and progression (p = 0.010, p = 0.016, and p = 0.008, respectively). UTUC patients with preoperative CKD had a higher risk of poor overall survival, cancer-specific survival, and progression-free survival after RNU than those without CKD.
