Abstract
488 Background: UTUC is rarer than bladder UC and typically responds poorly to standard chemotherapy. Analysis of 220 biomarker-evaluable atezo-treated patients (pts) in phase II/III trials suggested worse outcomes in UT vs lower tract UC [Galsky, ESMO 2018]. We explored clinical outcomes in pts with UTUC (renal pelvis or ureter) treated with atezo in the SAUL study. Methods: The single-arm SAUL study (NCT02928406) [Sternberg, Eur Urol 2019] enrolled a broader pt population, including pts with poor clinical characteristics and/or immune-mediated conditions, more representative of real-world practice than typically enrolled in randomized phase III immunotherapy trials. Pts with urinary tract carcinoma received atezo 1200 mg q3w until disease progression/unacceptable toxicity. Baseline characteristics, safety and efficacy were analyzed in subgroups of pts with UTUC (subdivided into renal pelvis or ureter UC) vs bladder UC. Results: Baseline characteristics in the 4 subgroups were generally similar, except for a numerically lower proportion of pts with 0 prior lines of therapy for metastatic disease in the UTUC vs bladder UC subgroup (30% vs 41%). Treatment exposure, safety and efficacy are shown below. Conclusions: These exploratory analyses of SAUL showed very similar efficacy and safety in UT vs bladder UC. This provides reassurance that atezo is active and has an acceptable safety profile in pts with UTUC, who are generally expected to have worse outcomes than bladder UC pts. Clinical trial information: NCT02928406 . [Table: see text]

Abstract
102 Background: KEYNOTE-365 (NCT02861573) is a phase 1b/2 study evaluating pembro in combination with other agents in mCRPC. An earlier report of cohort C showed activity and acceptable safety with pembro + enza. Updated results from cohort C are reported. Methods: Pts who failed or became intolerant to ≥4 wks of abi in prechemotherapy mCRPC state and whose disease progressed within 6 mo of screening per PSA progression or radiologic bone or soft tissue progression enrolled. Pts received pembro 200 mg IV Q3W with enza 160 mg/day PO. Primary end points: safety, PSA response rate (confirmed PSA decline ≥50%), and objective response rate (ORR) per blinded independent central review. Key secondary end points: disease control rate (DCR), duration of response (DOR), time to PSA progression, rPFS, and OS. Results: Of 102 treated pts, 73 discontinued, primarily due to progression (60%). Median age was 70 y (range, 43-87), 29% were PD-L1+, 17% had visceral disease, and 39% had measurable disease. Median follow up was 13 mo for all patients (n=102) and 17 mo for patients with ≥27 wks’ follow-up (n=69). See Table for efficacy outcomes. Treatment-related AEs occurred in 92 pts (90%); most frequent (≥20%) were fatigue (38%), nausea (22%), and rash (20%). Grade 3-5 treatment-related AEs occurred in 40 pts (39%). Three pts died of AEs (1 AE was treatment related [cause unknown]). Conclusions: With additional follow-up, pembro + enza continued to show activity in pts with abi-pretreated mCRPC. Safety of the combination was consistent with known profiles of pembro and enza. Clinical trial information: NCT02861573. [Table: see text]

Abstract
BACKGROUND Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts prior to voting during a consensus conference. SETTING Online Delphi survey and consensus conference. PARTICIPANTS The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), and 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS Overall, 116 statements were included in the Delphi survey. Of these statements, 33 (28%) achieved level 1 consensus and 49 (42%) achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease, and the evolving role of checkpoint inhibitor therapy in metastatic disease. CONCLUSIONS These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time when further evidence is available to guide our approach. PATIENT SUMMARY This report summarises findings from an international, multistakeholder project organised by the EAU and ESMO. In this project, a steering committee identified areas of bladder cancer management where there is currently no good-quality evidence to guide treatment decisions. From this, they developed a series of proposed statements, 71 of which achieved consensus by a large group of experts in the field of bladder cancer. It is anticipated that these statements will provide further guidance to health care professionals and could help improve patient outcomes until a time when good-quality evidence is available.

Radiation therapy before radical cystectomy combined with immunotherapy in locally advanced bladder cancer - study protocol of a prospective, single arm, multicenter phase II trial (RACE IT). BMC Cancer 2020; 20:8.

Abstract
Background Patients with locally advanced bladder cancer (cT3/4 cN0/N+ cM0) have a poor prognosis despite radical surgical therapy and perioperative chemotherapy. Preliminary data suggest that the combination of radiation and immunotherapy does not lead to excess toxicity and may have synergistic (abscopal) anti-tumor effects. We hypothesize that the combined preoperative application of the PD-1 checkpoint-inhibitor Nivolumab with concomitant radiation therapy of the bladder and pelvic region followed by radical cystectomy with standardized lymphadenectomy is safe and feasible and might improve outcome for patients with locally advanced bladder cancer. Methods Study design: “RACE IT” (AUO AB 65/18) is an investigator initiated, prospective, multicenter, open, single arm phase II trial sponsored by Technical University Munich. Study drug and funding are provided by the company Bristol-Myers Squibb. Study treatment: Patients will receive Nivolumab 240 mg i.v. every 2 weeks for 4 cycles preoperatively with concomitant radiation therapy of bladder and pelvic region (max. 50.4 Gy). Radical cystectomy with standardized bilateral pelvic lymphadenectomy will be performed between week 11–15. Primary endpoint: Rate of patients with completed treatment consisting of radio-immunotherapy and radical cystectomy at the end of week 15. Secondary endpoints: Acute and late toxicity, therapy response and survival (1 year follow up). Main inclusion criteria: Patients with histologically confirmed, locally advanced bladder cancer (cT3/4, cN0/N+), who are ineligible for neoadjuvant, cisplatin-based chemotherapy or who refuse neoadjuvant chemotherapy. Main exclusion criteria: Patients with metastatic disease (lymph node metastasis outside pelvis or distant metastasis) or previous chemo-, immune- or radiation therapy. Planned sample size: 33 patients, interim analysis after 11 patients. Discussion This trial aims to evaluate the safety and feasibility of the combined approach of preoperative PD-1 checkpoint-inhibitor therapy with concomitant radiation of bladder and pelvic region followed by radical cystectomy. The secondary objectives of therapy response and survival are thought to provide preliminary data for further clinical evaluation after successful completion of this trial. Recruitment has started in February 2019. Trial registration Protocol Code RACE IT: AB 65/18; EudraCT: 2018–001823-38; Clinicaltrials.gov: NCT03529890; Date of registration: 27 June 2018.

Abstract
BACKGROUND Beside the classical anticancer treatment tumor patients try to find proactive alternative therapies to fight their disease. Lifestyle changes such as introducing a ketogenic diet is one of the most popular among them. The German Association of Urological Oncology (AUO, Arbeitsgemeinschaft Urologische Onkologie) presents a systematic review investigating the evidence of ketogenic diet in cancer patients. MATERIALS AND METHODS A systematic literature research was conducted in the databases Medline, Livivo, and the Cochrane Library. Only clinical studies of tumor patients receiving chemotherapy while on a ketogenic diet were included. The assessment of the results was performed according to the predefined primary endpoints overall survival and progression-free survival and secondary endpoints quality of life and reduction of adverse effects induced by cytostatics. RESULTS Nine studies met the inclusion criteria: eight prospective and one retrospective study case series respectively cohort-studies, with a total of 107 patients. Currently there is no evidence of a therapeutic effect of a ketogenic diet in patients with malignant tumors regarding the clinical outcome or quality of life. CONCLUSION Based on the current data, a ketogenic diet can not be recommended to cancer patients because prospective, randomized trials are missing.

Abstract
This review summarises the treatment strategies of the last five decades for metastatic urothelial cancer. The introduction of combination chemotherapy in the mid-1980s led to clinically significant response rates and prolonged survival. Two years ago, the results of a phase-3 clinical trial with the PD1 inhibitor pembrolizumab for second-line treatment of metastatic urothelial carcinoma were published. These data were the first to show an overall survival benefit in comparison with a conventional chemotherapy with vinflunine, docetaxel or paclitaxel. Currently, PD1/PD-L1 inhibitors are also tested within randomized phase-3-trials for first-line treatment using different approaches either as a monotherapy or a combination with conventional chemotherapy or CTLA-4 inhibitors. Whereas data from single-arm phase-2 clinical trials have already been published, first phase-3 data are expected in 2019.

Abstract
5010 Background: Pembro has activity as monotherapy in pts with pretreated advanced mCRPC. A phase 2 study suggested that pembro + enza after progression on enza may have clinical activity. Data from cohort C (pembro + enza) of KEYNOTE-365 (NCT02861573), a phase 1b/2 umbrella study to test combinations in mCRPC, are presented. Methods: Pts who were unsuccessful with or became intolerant to ≥4 weeks of abi in the prechemotherapy mCRPC state, with either PSA or radiologic progression within 6 mo before screening were included. Pts received pembro 200 mg IV Q3W with enza 160 mg/day orally. Primary end points were safety and PSA response rate (confirmed PSA decrease ≥50%). Key secondary end points were investigator-assessed ORR (RECIST v1.1), disease control rate (DCR: CR+PR+SD ≥6 mo), time to PSA progression, rPFS, and OS. Results: 69 pts began treatment (median age, 69 y; visceral disease, 26%; measurable disease, 36%). Median (95% CI) follow-up was 9 (7-13) mo. Efficacy is outlined in the table. Treatment-related AEs occurred in 63 (91%) pts; most frequent (≥20%) were fatigue (30%), rash (23%), and nausea (22%). Grade 3/4 treatment-related AEs occurred in 28 (41%) pts; most common was rash (10%); no deaths were from treatment-related AEs. Conclusions: The pembro + enza combination showed sustained activity in abi-pretreated chemotherapy-naive mCRPC. AEs were considered tolerable for the treatment combination; incidence of rash resolved with standard-of-care treatment. Clinical trial information: NCT02861573. [Table: see text]

Abstract
5027 Background: Individual activity with pembro or olaparib has been observed in mCRPC pts who progressed on second-generation hormone therapy (HT) and chemotherapy. Data from cohort A (pembro+olaparib) of KEYNOTE-365 (NCT02861573), a phase 1b/2 umbrella study to test combinations in mCRPC, are presented. Methods: Pts with mCRPC who progressed within 6 mo before screening, were docetaxel-pretreated (up to 1 other chemotherapy permitted) for mCRPC and had ≤2 second-generation HTs were eligible. Pts received pembro 200 mg IV Q3W+olaparib 400 mg orally twice daily. Primary end points: safety and PSA response rate (confirmed PSA decrease ≥50%). Key secondary end points: ORR per RECIST v1.1 (investigator review), disease control rate (DCR: CR+PR+SD ≥6 mo), time to PSA progression, composite response rate, rPFS, and OS. Results: Median (95% CI) follow-up was 11 (6-15) mo. 41 pts initiated treatment (median age, 69 y; visceral disease, 42%; RECIST-measurable, 68%; homologous recombination deficient detected, 0%). Efficacy is outlined in the table. Treatment-related AEs occurred in 39 (95%) pts; most frequent (≥30%) were anemia (37%), fatigue (34%), and nausea (34%). Grade 3-5 treatment-related AEs occurred in 21 (51%) pts. There were 2 deaths; 1 was treatment-related (cause unknown). Conclusions: Pembro+olaparib had activity in pts with mCRPC who were molecularly unselected and were previously treated with docetaxel and second-generation HT. The observed safety profile for the combination is consistent with individual profiles of pembro and olaparib. Clinical trial information: NCT02861573. [Table: see text]

Abstract
5029 Background: Pembro had activity as monotherapy in pretreated advanced mCRPC. Data are presented here from cohort B (pembro + docetaxel/prednisone) of KEYNOTE-365 (NCT02861573), a phase 1b/2 umbrella study to test combinations in mCRPC. Methods: Pts who progressed on or became intolerant to ≥4 wk of abi or enza in the prechemotherapy mCRPC state and progressed within 6 mo before screening were eligible. Pts received pembro 200 mg IV with docetaxel 75 mg/m2 IV Q3W plus prednisone 5 mg orally twice daily. The primary end points were safety and PSA response rate (confirmed PSA decrease ≥50%). Key secondary end points were investigator-determined ORR (RECIST v1.1), disease control rate (DCR: CR+PR+SD ≥6 mo), time to PSA progression, rPFS, and OS. Results: 72 pts (median age, 68 y; visceral disease, 36%; measurable disease, 50%) began pembro + docetaxel. Median (95% CI) follow-up was 10 (8-12) mo. Efficacy is outlined in the table. Treatment-related AEs occurred in 69 (96%) pts; most frequent (≥30%) were alopecia (43%), fatigue (40%), and diarrhea (39%). Grade 3-5 treatment-related AEs occurred in 27 (38%) pts, including 2 deaths from treatment-related AEs (pneumonitis). Most commonly reported immune-mediated AEs were infusion-related reactions (11%) and colitis (10%). Conclusions: Pembro + docetaxel/prednisone has activity in pts with mCRPC who previously progressed on second-generation hormone therapy. AEs were considered mild for the treatment combination.

Abstract
4524 Background: In the open-label, single-arm, phase 2 CheckMate 275 trial, objective response rate (ORR) for patients (pts) with metastatic urothelial carcinoma (mUC) with nivolumab (NIVO) was 20.4% with minimum follow-up of 21.3 mo. Here, we report updated efficacy and safety data with minimum follow-up of 33.7 mo. Methods: Pts with platinum-resistant locally advanced or metastatic urothelial carcinoma received NIVO 3 mg/kg until disease progression or unacceptable toxicity. The primary endpoint was ORR by blinded independent review committee (BIRC) by RECIST v1.1 (including duration of response [DOR]). Secondary endpoints included progression-free survival (PFS) by BIRC, overall survival (OS), and ORR per investigator. Efficacy was evaluated in all treated pts and by tumor PD-L1 expression. Safety and PFS by investigator were exploratory endpoints. Results: ORR by BIRC was 20.7% (95% CI 16.1–26.1) including 18 (7%) complete responses (CR; with 1 additional CR since the last report; Table). ORR per investigator was similar (24.8%). Median DOR by BIRC was 20.3 mo (95% CI 11.5–31.3). Of 56 pts with best overall response (BOR) of CR or partial response (PR), 59% had a DOR ≥12 mo. Median PFS (mPFS) was 1.9 mo per BIRC (95% CI 1.9–2.3; Table) and 2.0 mo per investigator (95% CI 1.9–2.5). Median OS (mOS) was 8.6 mo (95% CI 6.1–11.3; Table). 12, 24, and 36-mo OS rates were 40%, 30%, and 22%. While efficacy was numerically higher in pts with tumor PD-L1 expression ≥1%, efficacy was observed in all pts (Table). Any-grade treatment-related adverse events occurred in 69% of pts (grade 3–4, 25%), mostly (59%) within the first 3 mo of initiating therapy. Conclusions: With long-term follow-up from CheckMate 275, NIVO continues to provide durable antitumor activity in pts with mUC. No new safety signals were noted. Clinical trial information: NCT02387996. [Table: see text]

Abstract
170 Background: Pembro had antitumor activity as monotherapy in pretreated advanced mCRPC (KEYNOTE-028; KEYNOTE-199). KEYNOTE-365 (NCT02861573) is a phase 1b/2 umbrella study testing combinations in mCRPC; we report early results from cohort B combining pembro + docetaxel in mCRPC. Methods: Pts who failed or became intolerant to ≥4 weeks of abi or enza in the pre-chemotherapy mCRPC state received pembro 200 mg IV with docetaxel 75 mg/m2 IV Q3W plus prednisone 5 mg orally twice daily. Pts also progressed within 6 months prior to screening as determined by either PSA progression or radiologic progression in bone or soft tissue. Response was evaluated by PSA levels Q3W and imaging Q9W for first year and Q12W thereafter. Primary end points: safety and PSA response rate (confirmed PSA decline ≥50%). Key secondary end points: investigator-determined ORR (RECIST v1.1), disease control rate (DCR: CR+PR+SD ≥6 mo), time to PSA progression, rPFS, and OS. Results: 72 pts (median age 68 years; PD-L1+ 29%; visceral disease 36%; measurable disease 50%) initiated pembro + docetaxel. Median (95% CI) follow-up was 10 (8-12) mo. Efficacy is outlined in table below. Treatment-related AEs occurred in 69 (96%) pts; most frequent (≥30%) were alopecia (43%), fatigue (40%), and diarrhea (39%). Grade 3-5 treatment-related AEs occurred in 27 (38%) pts, including 2 deaths due to treatment-related AEs (pneumonitis). Conclusions: Combination of pembro + docetaxel/prednisone has activity in pts with mCRPC previously failing anti-hormonal therapy. Observed safety profile for the combination was consistent with known safety profile of each component. Clinical trial information: NCT02861573. [Table: see text]

Abstract
145 Background: Activity with pembro or olaparib has been observed in mCRPC pts who progressed on 2nd-generation hormonal therapy (HT) and chemotherapy. From KEYNOTE-365 (NCT02861573), a phase 1b/2 umbrella study testing combinations in mCRPC, we report early results from cohort A combining pembro + olaparib. Methods: Pts with mCRPC were eligible if they progressed within 6 months prior to screening determined by either PSA progression or radiologic progression in bone or soft tissue. Pts were docetaxel-pretreated for mCRPC, may have received 1 other chemotherapy, and had ≤2 2nd-generation HT. Pts received pembro 200 mg IV Q3W + olaparib 400 mg orally twice daily. Primary end points: safety and PSA response rate (confirmed PSA decline ≥50%). Key secondary end points: ORR RECIST v1.1 (investigator review), disease control rate (DCR: CR+PR+SD ≥6 mo), time to PSA progression, composite response rate (ORR RECIST v1.1, confirmed PSA response, or confirmed decrease in circulating tumor cell count from ≥5 to <5 cells/7.5 mL blood), rPFS, and OS. Results: Median follow-up was 11 mo. 41 initiated treatment (median age 69 years; PD-L1+ 27%; visceral disease 42%; RECIST-measurable 68%; homologous recombination repair mutation [HRR] 0%). See efficacy in table below. Treatment-related AEs occurred in 39 (95%) pts. Most frequent (≥30%) were anemia (37%), fatigue (34%), and nausea (34%). Grade 3-5 treatment-related AEs were in 21 (51%) pts. There were 2 deaths; only 1 was treatment-related (cause unknown). Conclusions: Combination of pembro + olaparib has activity in pts previously treated with docetaxel and ≤2 2nd-generation HT for mCRPC and who are HRR wild type. Observed safety profile for the combination is consistent with individual profiles of pembro and olaparib. Clinical trial information: NCT02861573. [Table: see text]

Abstract
171 Background: Pembro has antitumor activity as monotherapy in pretreated advanced mCRPC (KEYNOTE-028; KEYNOTE-199). A study has suggested that pembro + enza after progression on enza may have clinical activity. KEYNOTE-365 (NCT02861573) is a phase 1b/2 umbrella study testing combinations in mCRPC; we report early results from cohort C combining pembro + enza in mCRPC. Methods: Patients who failed or became intolerant to ≥4 weeks of abi in the pre-chemotherapy mCRPC state were included. Pts also had to have progressed within 6 months prior to screening as determined by either PSA progression or radiologic progression in bone or soft tissue. Pts received pembro 200 mg intravenously Q3W with enza 160 mg per day orally, and response was evaluated by PSA levels Q3W and imaging Q9W for the first year and Q12W thereafter. Primary end points were safety and PSA response rate (confirmed PSA decline ≥50%). Key secondary end points were investigator-assessed ORR (RECIST v1.1), disease control rate (DCR: CR+PR+SD ≥6 mo), time to PSA progression, rPFS, and OS. Results: 69 pts initiated treatment (median age 69 years; PD-L1+ 30%; visceral disease 26%; measurable disease 36%). Median (95% CI) follow-up was 9 (7-13) mo. See efficacy outcomes in table. Treatment-related AEs occurred in 63 (91%) pts; most frequent (≥20%) were fatigue (30%), rash (23%), and nausea (22%). Grade 3-4 treatment-related AEs occurred in 28 (41%) pts; no deaths were due to treatment-related AEs. Conclusions: Early results from the pembro + enza combination show sustained activity in abi-pretreated frontline mCRPC. Observed safety profile for the combination treatment was consistent with the known safety profiles of pembro and enza. Clinical trial information: NCT02861573. [Table: see text]

Abstract
PURPOSE This trial compared the sequential therapy with the multikinase inhibitor sorafenib (So) followed by pazopanib (Pa) or vice versa in advanced/metastatic renal cell carcinoma (mRCC) patients. METHODS This multicenter, randomized phase 3 study assessed the sequential use of So-Pa versus Pa-So in patients with mRCC without prior systemic therapy. Pts were randomized to So 2 × 400 mg/day followed by Pa 1 × 800 mg/day in case of progression or intolerable toxicity or vice versa. Primary endpoint was total PFS (tPFS), defined as time from randomization to progression, or death during second-line therapy. Key secondary endpoints included overall survival (OS), first-line PFS, disease control rate (DCR) and safety. RESULTS A total of 377 pts were randomized (So-Pa, n = 189; Pa-So, n = 188). Recruitment of a total 544 pts was calculated, but actual accrual rate turned out to be lower than expected. The primary endpoint median tPFS was 8.6 mo (95% CI 7.7-10.2) for So-Pa and 12.9 mo (95% CI 10.8-15.2) for Pa-So with a hazard ratio (HR) of 1.36 (upper limit of one-sided 95% CI 1.68), which exceeded a predefined HR <1.225 as a one-sided 95% confidence interval. Non-inferiority of So-Pa regarding tPFS was not met. Secondary endpoints displayed marked statistical differences in favor of Pa-So in first-line PFS and DCR but not for OS and 2nd-line PFS. Side effect profiles were consistent with known toxicities of the respective multikinase-inhibitor including diarrhea, fatigue, hand-foot skin reaction and hypertension. CONCLUSIONS Non-inferiority of the primary endpoint tPFS could not be demonstrated for So-Pa. The results for first-line PFS and DCR favored the Pa-So sequence.

Abstract
Our aim was to retrospectively evaluate the feasibility of rechallenge 177Lu-prostate-specific membrane antigen (177Lu-PSMA) radioligand therapy. Methods: Rechallenge radioligand therapy was defined as subsequent treatment with 177Lu-PSMA after initial exposure with an excellent response followed by progression. Biochemical, radiographic, clinical antitumor response, and adverse events were analyzed. Prostate-specific antigen (PSA) progression-free survival (PFS) and overall survival were calculated. Results: Eight patients underwent a median of 2 (range: 1-4) cycles of rechallenge with 177Lu-PSMA for imaging and therapy. A maximum PSA decrease of 50% was achieved in 3 patients (37.5%). Radiographic response was favorable in 3 patients, whereas 4 exhibited progressive disease. Eastern Cooperative Oncology Group performance status was stable during therapy in all patients. No grade 4 toxicity was noticed, and grade 3 toxicity occurred in 3 patients (37.5%). The median PSA-PFS and overall survival were 3.2 mo (95% confidence interval, 2.6-3.7 mo) and 14.0 mo (95% confidence interval, 6.2-21.8 mo), respectively. Conclusion: In a small patient cohort with an initial excellent response, 177Lu-PSMA rechallenge is still active, with lower efficacy and higher toxicity.

Abstract
BACKGROUND The extent of lymph node dissection (LND) in bladder cancer (BCa) patients at the time of radical cystectomy may affect oncologic outcome. OBJECTIVE To evaluate whether extended versus limited LND prolongs recurrence-free survival (RFS). DESIGN, SETTING, AND PARTICIPANTS Prospective, multicenter, phase-III trial patients with locally resectable T1G3 or muscle-invasive urothelial BCa (T2-T4aM0). INTERVENTION Randomization to limited (obturator, and internal and external iliac nodes) versus extended LND (in addition, deep obturator, common iliac, presacral, paracaval, interaortocaval, and para-aortal nodes up to the inferior mesenteric artery). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was RFS. Secondary endpoints included cancer-specific survival (CSS), overall survival (OS), and complications. The trial was designed to show 15% advantage of 5-yr RFS by extended LND. RESULTS AND LIMITATIONS In total, 401 patients were randomized from February 2006 to August 2010 (203 limited, 198 extended). The median number of dissected nodes was 19 in the limited and 31 in the extended arm. Extended LND failed to show superiority over limited LND with regard to RFS (5-yr RFS 65% vs 59%; hazard ratio [HR]=0.84 [95% confidence interval 0.58-1.22]; p=0.36), CSS (5-yr CSS 76% vs 65%; HR=0.70; p=0.10), and OS (5-yr OS 59% vs 50%; HR=0.78; p=0.12). Clavien grade ≥3 lymphoceles were more frequently reported in the extended LND group within 90d after surgery. Inclusion of T1G3 tumors may have contributed to the negative study result. CONCLUSIONS Extended LND failed to show a significant advantage over limited LND in RFS, CSS, and OS. A larger trial is required to determine whether extended compared with limited LND leads to a small, but clinically relevant, survival difference (ClinicalTrials.gov NCT01215071). PATIENT SUMMARY In this study, we investigated the outcome in bladder cancer patients undergoing cystectomy based on the anatomic extent of lymph node resection. We found that extended removal of lymph nodes did not reduce the rate of tumor recurrence in the expected range.
