Abstract/Text: BACKGROUND: The literature on upper tract urothelial carcinoma (UTUC) has been limited to small, single center studies. A large series of patients treated with radical nephroureterectomy for UTUC were studied, and variables associated with poor prognosis were identified.
METHODS: Data on 1363 patients treated with radical nephroureterectomy at 12 academic centers were collected. All pathologic slides were re-reviewed by genitourinary pathologists according to strict criteria.
RESULTS: Pathologic review revealed renal pelvis location (64%), necrosis (21.6%), lymphovascular invasion (LVI) (24.8%), concomitant carcinoma in situ (28.7%), and high-grade disease (63.7%). A total of 590 patients (43.3%) underwent concurrent, lymphadenectomy and 135 (9.9%) were lymph node (LN) -positive. Over a mean follow-up of 51 months, 379 (28%) patients experienced disease recurrence outside of the bladder and 313 (23%) died of UTUC. The 5-year recurrence-free and cancer-specific survival probabilities (+/-SD) were 69%+/-1% and 73%+/-1%, respectively. On multivariate analysis, high tumor grade (hazards ratio [HR]: 2.0, P<.001), advancing pathologic T stage (P-for-trend<.001), LN metastases (HR: 1.8, P<.001), infiltrative growth pattern (HR: 1.5, P<.001), and LVI (HR: 1.2, P=.041) were associated with disease recurrence. Similarly, patient age (HR: 1.1, P=.001), high tumor grade (HR: 1.7, P=.001), increasing pathologic T stage (P-for-trend<.001), LN metastases (HR: 1.7, P<.001), sessile architecture (HR: 1.5, P=.002), and LVI (HR: 1.4, P=.02) were independently associated with cancer-specific survival.
CONCLUSIONS: Radical nephroureterectomy provided durable local control and cancer-specific survival in patients with localized UTUC. Pathologic tumor grade, T stage, LN status, tumor architecture, and LVI were important prognostic variables associated with oncologic outcomes, which could potentially be used to select patients for adjuvant systemic therapy.

1: Gemcitabine and cisplatin in locally advanced and metastatic bladder cancer; 3- or 4-week schedule?
著者: Anne Birgitte Als, Lisa Sengelov, Hans Von Der Maase
雑誌名: Acta Oncol. 2008;47(1):110-9. doi: 10.1080/02841860701499382.
Abstract/Text: BACKGROUND: Chemotherapy with gemcitabine and cisplatin (GC) is an active regimen in advanced transitional cell carcinoma (TCC). Traditionally, GC has been administered as a 4-week schedule. However, an alternative 3-week schedule may be more feasible. Long-term survival data for the alternative 3-week schedule and comparisons of the feasibility and toxicity between the two schedules have not previously been published.
MATERIAL AND METHODS: We performed a retrospective analysis of patients with stage IV TCC, treated with GC by a standard 4-week or by an alternative 3-week schedule.
RESULTS: A total of 212 patients received GC (3-week; n = 151, 4-week; n = 61). We found no statistical differences in overall survival between the two schedules (hazard ratio 1.15, 95% CI 0.83-1.59), p = 0.40). Five-year survival rates were 14.9% and 11.8% for the 3- and 4-week schedule, respectively (p = 0.94). Response rates were 59.7% and 55.6%, respectively (p = 0.61). Toxicity was less pronounced in the 3-week schedule with regards to neutropenia, thrombocytopenia, and transfusion rates. Hematologic toxicity at day 15 in the 4-week schedule was common, leading to dose omissions in 47% of cycles. Dose intensity for gemcitabine was accordingly lower in the 4 week-schedule. The higher dose intensity of cisplatin in the 3-week schedule, did not lead to increased renal toxicity. In 13 patients with impaired renal function, cisplatin was split into 2 days, which was feasible and efficient.
CONCLUSION: Efficacy parameters for the GC 3-week schedule were comparable to those for the 4-week schedule, whereas toxicity was less pronounced. The 3-week schedule may be an effective and feasible alternative GC-schedule.

Abstract/Text: PURPOSE: To compare long-term survival in patients with locally advanced or metastatic transitional cell carcinoma (TCC) of the urothelium treated with gemcitabine/cisplatin (GC) or methotrexate/vinblastine/doxorubicin/cisplatin (MVAC).
PATIENTS AND METHODS: Efficacy data from a large randomized phase III study of GC versus MVAC were updated. Time-to-event analyses were performed on the observed distributions of overall and progression-free survival.
RESULTS: A total of 405 patients were randomly assigned: 203 to the GC arm and 202 to the MVAC arm. At the time of analysis, 347 patients had died (GC arm, 176 patients; MVAC arm, 171 patients). Overall survival was similar in both arms (hazard ratio [HR], 1.09; 95% CI, 0.88 to 1.34; P = .66) with a median survival of 14.0 months for GC and 15.2 months for MVAC. The 5-year overall survival rates were 13.0% and 15.3%, respectively (P = .53). The median progression-free survival was 7.7 months for GC and 8.3 months for MVAC, with an HR of 1.09. The 5-year progression-free survival rates were 9.8% and 11.3%, respectively (P = .63). Significant prognostic factors favoring overall survival included performance score (> 70), TNM staging (M0 v M1), low/normal alkaline phosphatase level, number of disease sites (CONCLUSION: Long-term overall and progression-free survival after treatment with GC or MVAC are similar. These results strengthen the role of GC as a standard of care in patients with locally advanced or metastatic TCC.

1: European guidelines for the diagnosis and management of upper urinary tract urothelial cell carcinomas: 2011 update.
著者: Morgan Rouprêt, Richard Zigeuner, Juan Palou, Andreas Boehle, Eero Kaasinen, Richard Sylvester, Marko Babjuk, Willem Oosterlinck
雑誌名: Eur Urol. 2011 Apr;59(4):584-94. doi: 10.1016/j.eururo.2010.12.042. Epub 2011 Jan 14.
Abstract/Text: CONTEXT: The European Association of Urology (EAU) Guideline Group for urothelial cell carcinoma of the upper urinary tract (UUT-UCC) has prepared new guidelines to aid clinicians in assessing the current evidence-based management of UUT-UCC and to incorporate present recommendations into daily clinical practice.
OBJECTIVE: This paper provides a brief overview of the EAU guidelines on UUT-UCC as an aid to clinicians in their daily practice.
EVIDENCE ACQUISITION: The recommendations provided in the current guidelines are based on a thorough review of available UUT-UCC guidelines and papers identified using a systematic search of Medline. Data on urothelial malignancies and UUT-UCCs in the literature were searched using Medline with the following keywords: urinary tract cancer, urothelial carcinomas, upper urinary tract, carcinoma, transitional cell, renal pelvis, ureter, bladder cancer, chemotherapy, nephroureterectomy, adjuvant treatment, neoadjuvant treatment, recurrence, risk factors, and survival. A panel of experts weighted the references.
EVIDENCE SYNTHESIS: There is a lack of data in the current literature to provide strong recommendations due to the rarity of the disease. A number of recent multicentre studies are now available, whereas earlier publications were based only on limited populations. However, most of these studies have been retrospective analyses. The TNM classification 2009 is recommended. Recommendations are given for diagnosis as well as for radical and conservative treatment; prognostic factors are also discussed. Recommendations are provided for patient follow-up after different therapeutic options.
CONCLUSIONS: These guidelines contain information for the diagnosis and treatment of individual patients according to a current standardised approach. When determining the optimal treatment regimen, physicians must take into account each individual patient's specific clinical characteristics with regard to renal function including medical comorbidities; tumour location, grade and stage; and molecular marker status.

雑誌名: Ann Oncol. 2019 Jun 1;30(6):970-976. doi: 10.1093/annonc/mdz127.
Abstract/Text: BACKGROUND: Novel second-line treatments are needed for patients with advanced urothelial cancer (UC). Interim analysis of the phase III KEYNOTE-045 study showed a superior overall survival (OS) benefit of pembrolizumab, a programmed death 1 inhibitor, versus chemotherapy in patients with advanced UC that progressed on platinum-based chemotherapy. Here we report the long-term safety and efficacy outcomes of KEYNOTE-045.
PATIENTS AND METHODS: Adult patients with histologically/cytologically confirmed UC whose disease progressed after first-line, platinum-containing chemotherapy were enrolled. Patients were randomly assigned 1 : 1 to receive pembrolizumab [200 mg every 3 weeks (Q3W)] or investigator's choice of paclitaxel (175 mg/m2 Q3W), docetaxel (75 mg/m2 Q3W), or vinflunine (320 mg/m2 Q3W). Primary end points were OS and progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) by blinded independent central radiology review (BICR). A key secondary end point was objective response rate per RECIST v1.1 by BICR.
RESULTS: A total of 542 patients were enrolled (pembrolizumab, n = 270; chemotherapy, n = 272). Median follow-up as of 26 October 2017 was 27.7 months. Median 1- and 2-year OS rates were higher with pembrolizumab (44.2% and 26.9%, respectively) than chemotherapy (29.8% and 14.3%, respectively). PFS rates did not differ between treatment arms; however, 1- and 2-year PFS rates were higher with pembrolizumab. The objective response rate was also higher with pembrolizumab (21.1% versus 11.0%). Median duration of response to pembrolizumab was not reached (range 1.6+ to 30.0+ months) versus chemotherapy (4.4 months; range 1.4+ to 29.9+ months). Pembrolizumab had lower rates of any grade (62.0% versus 90.6%) and grade ≥3 (16.5% versus 50.2%) treatment-related adverse events than chemotherapy.
CONCLUSIONS: Long-term results (>2 years' follow-up) were consistent with those of previously reported analyses, demonstrating continued clinical benefit of pembrolizumab over chemotherapy for efficacy and safety for treatment of locally advanced/metastatic, platinum-refractory UC.
