RESUMO
BACKGROUND: Current tobacco smoking is independently associated with decreased overall survival (OS) among patients with metastatic renal cell carcinoma (mRCC) treated with targeted monotherapy (VEGF-TKI). Herein, we assess the influence of smoking status on the outcomes of patients with mRCC treated with the current first-line standard of care of immune checkpoint inhibitor (ICI)-based regimens. MATERIALS AND METHODS: Real-world data from the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) were collected retrospectively. Patients with mRCC who received either dual ICI therapy or ICI with VEGF-TKI in the first-line setting were included and were categorized as current, former, or nonsmokers. The primary outcomes were OS, time to treatment failure (TTF), and objective response rate (ORR). OS and TTF were compared between groups using the log-rank test and multivariable Cox regression models. ORR was assessed between the 3 groups using a multivariable logistic regression model. RESULTS: A total of 989 eligible patients were included in the analysis, with 438 (44.3%) nonsmokers, 415 (42%) former, and 136 (13.7%) current smokers. Former smokers were older and included more males, while other baseline characteristics were comparable between groups. Median follow-up for OS was 21.2 months. In the univariate analysis, a significant difference between groups was observed for OS (Pâ =â .027) but not for TTF (Pâ =â .9), with current smokers having the worse 2-year OS rate (62.8% vs 70.8% and 73.1% in never and former smokers, respectively). After adjusting for potential confounders, no significant differences in OS or TTF were observed among the 3 groups. However, former smokers demonstrated a higher ORR compared to never smokers (OR 1.45, Pâ =â .02). CONCLUSION: Smoking status does not appear to independently influence the clinical outcomes to first-line ICI-based regimens in patients with mRCC. Nonetheless, patient counseling on tobacco cessation remains a crucial aspect of managing patients with mRCC, as it significantly reduces all-cause mortality.

BACKGROUND: To the authors' knowledge, outcomes and prognostic tools have yet to be clearly defined in patients with metastatic renal cell carcinoma (mRCC) who are treated with immuno-oncology (IO) checkpoint inhibitors (programmed death-ligand 1 [PD-L1] inhibitors). In the current study, the authors aimed to establish IO efficacy benchmarks in patients with mRCC and update patient outcomes in each International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic class. METHODS: A retrospective analysis was performed using the IMDC database with data from 38 centers. It included patients with mRCC who were treated with ≥1 line of IO. Overall response rates (ORRs), duration of treatment (DOT), and overall survival (OS) were calculated. Patients were stratified using IMDC prognostic factors. RESULTS: A total of 687 patients (90% with clear cell and 10% with non-clear cell) were included. The ORR was 27% in evaluable patients (461 patients). In patients treated with first-line nivolumab and ipilimumab (49 patients), the combination of PD-L1 inhibitor and vascular endothelial growth factor inhibitor (72 patients), and PD-L1 inhibitor (51 patients), the ORR was 31%, 39%, and 40%, respectively, and the median DOT was 8.3 months, 14.7 months, and 8.3 months, respectively. The ORR for second-line, third-line, and fourth-line nivolumab was 22%, 24%, and 26%, respectively. The median DOT was 5.7 months, 6.2 months, and 8.3 months, respectively, in the second-line, third-line, and fourth-line settings. When segregated into IMDC favorable-risk, intermediate-risk, and poor-risk groups, the median OS rates for the first-line, second-line, third-line, and fourth-line treatment settings were not reached (NR), NR, and NR, respectively (P = .163); NR, 26.7 months, and 7.4 months, respectively (P < 0. 0001); 36.1 months, 28.2 months, and 11.1 months, respectively (P = .016); and NR, NR, and 6.7 months, respectively (P = .047). CONCLUSIONS: The ORR was not found to deteriorate from the first-line to the fourth-line of IO therapy. In the second line through fourth line, the IMDC criteria appropriately stratified patients into favorable-risk, intermediate-risk, and poor-risk groups for OS.

BACKGROUND: The Hedgehog pathway inhibitor vismodegib has shown clinical benefit in patients with advanced basal cell carcinoma and is approved for treatment of patients with advanced basal cell carcinoma for whom surgery is inappropriate. STEVIE was designed to assess the safety of vismodegib in a situation similar to routine practice, with a long follow-up. METHODS: In this multicentre, open-label trial, adult patients with histologically confirmed locally advanced basal cell carcinoma or metastatic basal cell carcinoma were recruited from regional referral centres or specialist clinics. Eligible patients were aged 18 years or older with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and adequate organ function. Patients with locally advanced basal cell carcinoma had to have been deemed ineligible for surgery. All patients received 150 mg oral vismodegib capsules once a day on a continuous basis in 28-day cycles. The primary objective was safety (incidence of adverse events until disease progression or unacceptable toxic effects), with assessments on day 1 of each treatment cycle (28 days) by principal investigator and coinvestigators at the site. Efficacy variables were assessed as secondary endpoints. The safety evaluable population included all patients who received at least one dose of study drug. Patients with histologically confirmed basal cell carcinoma who received at least one dose of study drug were included in the efficacy analysis. An interim analysis was pre-planned after 500 patients achieved 1 year of follow-up. This trial is registered with ClinicalTrials.gov, number NCT01367665. The study is still ongoing. FINDINGS: Between June 30, 2011, and Nov 6, 2014, we enrolled 1227 patients. At clinical cutoff (Nov 6, 2013), 499 patients (468 with locally advanced basal cell carcinoma and 31 with metastatic basal cell carcinoma) had received study drug and had the potential to be followed up for 12 months or longer. Treatment was discontinued in 400 (80%) patients; 180 (36%) had adverse events, 70 (14%) had progressive disease, and 51 (10%) requested to stop treatment. Median duration of vismodegib exposure was 36·4 weeks (IQR 17·7-62·0). Adverse events happened in 491 (98%) patients; the most common were muscle spasms (317 [64%]), alopecia (307 [62%]), dysgeusia (269 [54%]), weight loss (162 [33%]), asthenia (141 [28%]), decreased appetite (126 [25%]), ageusia (112 [22%]), diarrhoea (83 [17%]), nausea (80 [16%]), and fatigue (80 [16%]). Most adverse events were grade 1 or 2. We recorded serious adverse events in 108 (22%) of 499 patients. Of the 31 patients who died, 21 were the result of adverse events. As assessed by investigators, 302 (66·7%, 62·1-71·0) of 453 patients with locally advanced basal cell carcinoma had an overall response (153 complete responses and 149 partial responses); 11 (37·9%; 20·7-57·7) of 29 patients with metastatic basal cell carcinoma had an overall response (two complete responses, nine partial responses). INTERPRETATION: This study assessed the use of vismodegib in a setting representative of routine clinical practice for patients with advanced basal cell carcinoma. Our results show that treatment with vismodegib adds a novel therapeutic modality from which patients with advanced basal cell carcinoma can benefit substantially. FUNDING: F Hoffmann-La Roche.

BACKGROUND: Previous prognostic models for second-line systemic therapy in patients with metastatic renal cell carcinoma have not been studied in the setting of targeted therapy. We sought to validate the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) model in patients with metastatic renal cell carcinoma receiving next-line targeted therapy after progression on first-line targeted therapy. METHODS: In this population-based study, we analysed patients who received second-line targeted therapy for metastatic renal cell carcinoma at 19 centres in Canada, USA, Greece, Japan, Singapore, South Korea, and Denmark. The primary endpoint was overall survival since the initiation of second-line therapy. We compared the prognostic performance of the IMDC model with the three-factor MSKCC model used for previously treated patients for overall survival since the start of second-line targeted therapy. FINDINGS: Between Jan 1, 2005, and Nov 30, 2012, we included 1021 patients treated with second-line targeted therapy. Median overall survival since the start of second-line targeted therapy was 12·5 months (95% CI 11·3-14·3). Five of six predefined factors in the IMDC model (anaemia, thrombocytosis, neutrophilia, Karnofsky performance status [KPS] <80, and <1 year from diagnosis to first-line targeted therapy) were independent predictors of poor overall survival on multivariable analysis. The concordance index using all six prognostic factors (ie, also including hypercalcaemia) was 0·70 (95% CI 0·67-0·72) with the IMDC model and was 0·66 (95% CI 0·64-0·68) with the three-factor MSKCC model. When patients were divided into three risk categories using IMDC criteria, median overall survival was 35·3 months (95% CI 28·3-47·8) in the favourable risk group (n=76), 16·6 months (14·9-17·9) in the intermediate risk group (n=529), and 5·4 months (4·7-6·8) in the poor risk group (n=261). INTERPRETATION: The IMDC prognostic model can be applied to patients previously treated with targeted therapy, in addition to previously validated populations in first-line targeted therapy. The IMDC prognostic model in the second-line targeted therapy setting has an improved prognostic performance and is applicable to a more contemporary patient cohort than that of the three-factor MSKCC model.

INTRODUCTION: High-dose chemotherapy with autologous stem-cell transplantation (HDC-ASCT) is standard therapy for metastatic germ cell tumors (mGCTs) in patients whose disease progresses during or after conventional chemotherapy. We conducted a retrospective review of HDC-ASCT in relapsed mGCT patients in the province of Alberta, Canada, over the past two decades. METHODS: Patients with mGCTs who received HDC-ASCT at two provincial cancer referral centers from 2000-2018 were identified from institutional databases. Baseline clinical and treatment characteristics were collected, as well as overall survival (OS ) and disease-free survival (DFS). Relevant prognostic variables were analyzed. RESULTS: Forty-three patients were identified. The median age was 28 years (range 19-56). A majority (95%) had non-seminoma histology and testis/retroperitoneal primary (84%). Twenty patients (47%) had poor-risk disease, as per The International Germ Cell Consensus Classification (IGCCC), at start of first-line chemotherapy. HDC-ASCT was used as second-line therapy in 65% of patients, and 58% of ASCT patients received tandem transplants. Median followup after ASCT was 22 months (range 2-181). At last followup, 42% of patients were alive without disease, including 3/7 (43%) of patients with primary mediastinal disease. Two-year and five-year DFS/OS ratios were 44%/65% and 38%/45%, respectively. Median OS and DFS for all patients were 30.0 months (13.3-46.6) and 8.0 months (0.9-15.1), respectively. CONCLUSIONS: We found that HDC-ASCT is an effective salvage therapy in mGCT, consistent with existing literature. Patients appeared to benefit regardless of primary site. Although limited by small sample size, we found a numerical difference in DFS and OS between second- and third-line HDC-ASCT and single vs. tandem ASCT.
RESUMO
BACKGROUND: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has markedly increased over the last three decades due to newly found associations with human papillomavirus (HPV) infection. Primary radiotherapy (RT) is the treatment of choice for OPSCC at most centers, and over the last decade, the addition of concurrent chemotherapy has led to a significant improvement in survival, but at the cost of increased acute and late toxicity. Transoral robotic surgery (TORS) has emerged as a promising alternative treatment, with preliminary case series demonstrating encouraging oncologic, functional, and quality of life (QOL) outcomes. However, comparisons of TORS and RT in a non-randomized fashion are susceptible to bias. The goal of this randomized phase II study is to compare QOL, functional outcomes, toxicity profiles, and survival following primary RT (± chemotherapy) vs. TORS (± adjuvant [chemo] RT) in patients with OPSCC. METHODS/DESIGN: The target patient population comprises OPSCC patients who would be unlikely to require chemotherapy post-resection: Tumor stage T1-T2 with likely negative margins at surgery; Nodal stage N0-2, ≤3 cm in size, with no evidence of extranodal extension on imaging. Participants will be randomized in a 1:1 ratio between Arm 1 (RT ± chemotherapy) and Arm 2 (TORS ± adjuvant [chemo] RT). In Arm 1, patients with N0 disease will receive RT alone, whereas N1-2 patients will receive concurrent chemoradiation. In Arm 2, patients will undergo TORS along with selective neck dissections, which may be staged. Pathologic high-risk features will be used to determine the requirement for adjuvant radiotherapy +/- chemotherapy. The primary endpoint is QOL score using the M.D. Anderson Dysphagia Inventory (MDADI), with secondary endpoints including survival, toxicity, other QOL outcomes, and swallowing function. A sample of 68 patients is required. DISCUSSION: This study, if successful, will provide a much-needed randomized comparison of the conventional strategy of primary RT vs. the novel strategy of primary TORS. The trial is designed to provide a definitive QOL comparison between the two arms, and to inform the design of an eventual phase III trial for survival outcomes. TRIAL REGISTRATION: NCT01590355.

BACKGROUND: The combination of immuno-oncology (IO) agents ipilimumab and nivolumab (IPI-NIVO) and vascular endothelial growth factor targeted therapies (VEGF-TT) combined with IO (IO-VEGF) are current standard of care first-line treatments for metastatic renal cell carcinoma (mRCC). OBJECTIVE: To establish real-world clinical benchmarks for IO combination therapies based on the International mRCC Database Consortium (IMDC) criteria. DESIGN, SETTING, AND PARTICIPANTS: Patients with mRCC who received first-line IPI-NIVO, IO-VEGF, or VEGF-TT from 2002 to 2021 were identified using the IMDC database and stratified according to IMDC risk groups. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Overall survival (OS), time to next treatment (TTNT), and treatment duration (TD) were calculated using the Kaplan-Meier method and compared between IMDC risk groups within each treatment cohort by the log-rank test. The overall response rate (ORR) was calculated by physician assessment of the best overall response. The primary outcome was OS at 18 mo. RESULTS AND LIMITATIONS: In total, 728 patients received IPI-NIVO, 282 IO-VEGF, and 7163 VEGF-TT. The median follow-up times for patients remaining alive were 14.3 mo for IPI-NIVO, 14.9 mo IO-VEGF, and 34.4 mo for VEGF-TT. OS at 18 mo for favorable, intermediate, and poor risk was, respectively, 90%, 78%, and 50% for those receiving IPI-NIVO; 93%, 83%, and 74% for IO-VEGF; and 84%, 64%, and 28% for VEGF-TT. ORRs in favorable-, intermediate-, and poor-risk groups were 41.3%, 40.6%, and 33.0% for those receiving IPI-NIVO; 60.3%, 56.8%, and 40.9% for IO-VEGF; and 39.3%, 33.5%, and 20.9% for VEGF-TT, respectively. The IMDC model stratified patients into statistically distinct risk groups for the three endpoints of OS, TTNT, and TD within each treatment cohort. Limitations of this study were the retrospective design and short follow-up. CONCLUSIONS: This study demonstrated that the IMDC model continues to risk stratify patients with mRCC treated with contemporary first-line IO combination therapies and provided real-world survival benchmarks. PATIENT SUMMARY: The International Metastatic Renal Cell Carcinoma Database Consortium model continues to stratify patients with metastatic renal cell carcinoma receiving modern combination treatments in the real-world setting.

BACKGROUND: The role of cytoreductive nephrectomy (CN) has not yet been well characterized in the era of combination immunotherapy. OBJECTIVE: To evaluate characteristics and outcomes for patients with metastatic renal cell carcinoma (mRCC) who received immuno-oncology (IO)-based combination therapy according to CN status. DESIGN, SETTING, AND PARTICIPANTS: Using the International mRCC Database Consortium (IMDC), patients with mRCC who received frontline IO-based combinations were included. Upfront CN was defined as CN up to 3 mo before diagnosis of metastatic disease but before systemic therapy initiation. Deferred CN was defined as CN after systemic therapy initiation. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS: Overall survival (OS) from initiation of systemic therapy was estimated via Cox proportional-hazards regression. A 12-mo landmark time and a time-varying covariate for CN status were used to mitigate potential bias. RESULTS AND LIMITATIONS: Of the 385 patients eligible for landmark analysis, 24, 182, and 179 underwent deferred CN, upfront CN, and no CN, respectively. Patients in the no CN subgroup were older (63 yr vs 57 yr in the deferred CN subgroup and 60 yr in the upfront CN subgroup; p = 0.001) and a higher proportion had bone metastases (44% vs 26% in the deferred CN subgroup and 23% in the upfront CN subgroup; p < 0.001). A lower proportion of patients in the upfront CN subgroup had IMDC poor risk (23% vs 43% in the no CN subgroup and 47% in the deferred CN subgroup; p < 0.001). On multivariable analysis, CN receipt was an independent favorable prognostic factor (hazard ratio 0.45, 95% confidence interval 0.26-0.78; p = 0.005). The study is limited by the lack of randomization and its retrospective nature. CONCLUSIONS: Despite changes in practice patterns with the advent of novel therapeutic agents, CN may still serve as an effective surgical intervention in carefully selected patients. PATIENT SUMMARY: For patients with metastatic kidney cancer, surgery to remove the primary tumor was traditionally the treatment of choice, but immunotherapy drugs are now another option for these patients. We analyzed data for contemporary patients with metastatic kidney cancer who received combination immunotherapy as their first treatment. We found that in selected patients receiving immunotherapy, surgery to remove the primary tumor as well can result in better prognosis.
RESUMO
Importance: The association between treatment with first-line immuno-oncology (IO) combination therapies and physician-assessed objective imaging response among patients with metastatic renal cell carcinoma (mRCC) remains uncharacterized. Objective: To compare the likelihood of objective imaging response (ie, complete or partial response) to first-line IO combination ipilimumab-nivolumab (IOIO) therapy vs approved IO with vascular endothelial growth factor inhibitor (IOVE) combination therapies among patients with mRCC. Design, Setting, and Participants: This multicenter international cohort study was nested in routine clinical practice. A data set from the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) was used to identify consecutive patients with mRCC who received treatment with IO combination therapies between May 30, 2013, and September 9, 2021. A total of 899 patients with a histologically confirmed diagnosis of mRCC who received treatment with a first-line IOVE or IOIO regimen and had evaluable responses were included. Exposures: Best overall response to first-line IO combination therapy based on Response Evaluation Criteria in Solid Tumors, version 1.1. Main Outcomes and Measures: The primary outcome was the difference in treating physician-assessed objective imaging response based on the type of first-line IO combination therapy received. Secondary outcomes included the identification of baseline characteristics positively associated with objective imaging response and the association of objective imaging response with overall survival. Results: Among 1085 patients with mRCC who received first-line IO combination therapies, 899 patients (median age, 62.8 years [IQR, 55.9-69.2 years]; 666 male [74.2%]) had evaluable responses. A total of 794 patients had information available on IMDC risk classification; of those, 127 patients (16.0%) had favorable risk, 442 (55.7%) had intermediate risk, and 225 (28.3%) had poor risk. With regard to best overall response among all participants, 37 patients (4.1%) had complete response, 344 (38.3%) had partial response, 315 (35.0%) had stable disease, and 203 (22.6%) had progressive disease. Corresponding median overall survival was not estimable (95% CI, 53.3 months to not estimable) among patients with complete response, 55.9 months (95% CI, 44.1 months to not estimable) among patients with partial response, 48.1 months (95% CI, 33.4 months to not estimable) among patients with stable disease, and 13.0 months (95% CI, 8.4-18.1 months) among patients with progressive disease (log rank P < .001). Treatment with IOVE therapy was found to be independently associated with an increased likelihood of obtaining response (OR, 1.89; 95% CI, 1.26-2.81; P = .002) compared with IOIO therapy. The presence of lung metastases (odds ratio [OR], 1.49; 95% CI, 1.01-2.20), receipt of cytoreductive nephrectomy (OR, 1.59; 95% CI, 1.04-2.43), and favorable IMDC risk (OR, 1.93; 95% CI, 1.10-3.39) were independently associated with an increased likelihood of response. Conclusions and Relevance: In this study, treatment with IOVE therapy was associated with significantly increased odds of objective imaging response compared with IOIO therapy. The presence of lung metastases, receipt of cytoreductive nephrectomy, and favorable IMDC risk were associated with increased odds of experiencing objective imaging response. These findings may help inform treatment selection, especially in clinical contexts associated with high-volume multisite metastatic disease, in which obtaining objective imaging response is important.

OBJECTIVE: Older adults with metastatic renal cell carcinoma(mRCC) are underrepresented in immune-checkpoint inhibitor(ICI) registration trials. Here we compare the efficacy of ICI treatments in older vs. younger adults with mRCC. METHODS: Using the International mRCC Database Consortium(IMDC), patients treated with a PD(L)-1 based ICI were identified. Older adult was defined as ≥70-years at the time of treatment. Descriptive statistics were summarized in means, medians, and proportions. Effectiveness endpoints included overall survival (OS), time-to-treatment failure(TTF), time-to-next treatment(TNT), and overall response rate(ORR). Hazards ratios were adjusted(aHR) for IMDC risk factors, histology, line of treatment and older age. RESULTS: Of 1427 included patients, 397(28%) were older adults. ICI was used as 1st line(1 L) in 40%, 2nd line(2 L) in 49% and 3rd line(3 L) in 11% of patients. In univariable analysis, older adults had inferior OS compared to younger adults(25.1 m vs. 30.8 m, p < 0.01). There were no significant differences in TTF (6.9 m vs. 6.9 m, p = 0.4) or TNT(9.1 m vs 10 m, p = 0.3) between groups. In multivariable analyses, older age was not independently associated with worse OS(aHR = 1.02, p = 0.8), TTF(aHR = 0.95, p = 0.6) or TNT(aHR = 0.93, p = 0.5). Older adults had a lower ORR compared to younger adults(24% vs. 31%, p = 0.01), which was mainly driven by responses in 1 L(31% vs. 44%, p = 0.02) and not observed in 2 L/3 L. CONCLUSIONS: After multivariable analyses, older adults with mRCC treated with ICI had no difference in OS, TTF or TNT when compared to younger adults. Our data support that chronological older age should not preclude patients from receiving ICI based therapies.

BACKGROUND: The use of cytoreductive nephrectomy (CN) selectively for patients who show a favorable response to upfront systemic therapy may be an approach to select optimal candidates with metastatic renal cell carcinoma (mRCC) who are most likely to benefit. OBJECTIVE: We sought to characterize outcomes of deferred CN (dCN) after upfront sunitinib, outcomes relative to sunitinib alone, and outcomes of CN followed by sunitinib. DESIGN, SETTING, AND PARTICIPANTS: We used the prospectively maintained International mRCC Database Consortium (IMDC) database to identify patients with newly diagnosed mRCC (2006-2018). INTERVENTION: Sunitinib alone, upfront CN followed by sunitinib, sunitinib followed by dCN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Outcomes were overall survival (OS) and time to sunitinib treatment failure (TTF). Kaplan-Meier and multivariable Cox regression analyses were performed; dCN was analyzed as a time-varying covariate to account for immortal time bias. RESULTS AND LIMITATIONS: We evaluated 1541 patients, of whom 651 (42%) received sunitinib alone, 805 (52%) underwent CN followed by sunitinib, and 85 (5.5%) received sunitinib followed by dCN, at a median of 7.8 mo from diagnosis. Median OS periods for patients treated with sunitinib alone, CN followed by sunitinib, and sunitinib followed by dCN were 10, 19, and 46 mo, respectively, while the median TTF values were 4, 8, and 13 mo, respectively. In multivariable regression analyses, sunitinib followed by dCN was significantly associated with improved OS (hazard ratio [HR] = 0.45, 95% confidence interval [CI] 0.33-0.60, p < 0.001) and TTF (HR = 0.62, 95% CI 0.46-0.85, p = 0.003) versus sunitinib alone. Among CN-treated patients, sunitinib followed by dCN was associated with improved OS (HR = 0.52, 95% CI 0.39-0.70, p < 0.001) and TTF (HR = 0.71, 95% CI 0.56-0.90, p = 0.005) compared with upfront CN followed by sunitinib. In various sensitivity analyses, dCN remained significantly associated with improved OS and TTF. CONCLUSIONS: Patients who received dCN were carefully selected and achieved long OS. With these benchmark outcomes, optimal selection criteria need to be identified and confirmation of the role of dCN in a clinical trial is warranted. PATIENT SUMMARY: We characterized benchmark survival outcomes for patients with metastatic kidney cancer treated with sunitinib alone, nephrectomy (kidney removal) followed by sunitinib, and sunitinib followed by nephrectomy.

BACKGROUND: There is evidence that cytoreductive nephrectomy (CN) may be beneficial in metastatic renal cell carcinoma (mRCC). This has been studied predominantly in clear-cell RCC, with more limited data on the role of CN in patients with papillary histology. OBJECTIVE: To determine the benefit of CN in synchronous metastatic papillary RCC. DESIGN, SETTING, AND PARTICIPANTS: Using the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) database, a retrospective analysis was performed for patients with papillary mRCC treated with or without CN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Median overall survival (OS) and progression-free survival (PFS) were determined for both patient groups. Cox regression analysis was performed to control for imbalances in individual IMDC risk factors. RESULTS AND LIMITATIONS: In total, 647 patients with papillary mRCC were identified, of whom 353 had synchronous metastatic disease. Of these, 109 patients were treated with CN and 244 were not. The median follow-up was 57.1mo (95% confidence interval [CI] 32.9-77.8) and the OS from the start of first-line targeted therapy for the entire cohort was 13.2mo (95% CI 12.0-16.1). Median OS for patients with CN was 16.3mo, compared to 8.6mo (p<0.0001) in the no-CN group. When adjusted for individual IMDC risk factors, the hazard ratio (HR) of death for CN was 0.62 (95% CI 0.45-0.85; p=0.0031). Limitations include the retrospective nature of the analysis. CONCLUSIONS: The use of CN in patients with mRCC and papillary histology appears to be associated with better survival compared to no CN after adjustment for risk criteria. Selection of appropriate candidates for CN is crucial. A clinical trial in this rare population may not be possible. PATIENT SUMMARY: In a population of patients with advanced papillary kidney cancer, we found that surgical removal of the primary kidney tumor was associated with better overall survival.

BACKGROUND: Sunitinib is administered on a rigid schedule that may not be optimal for all patients. We hypothesised that toxicity-driven dose and schedule changes would optimise drug exposure and outcome for each patient. MATERIALS AND METHODS: In a phase 2 trial, 117 patients with metastatic clear cell renal cell cancer were started on sunitinib 50 mg/day with the aim to treat for 28 days. Treatment breaks were reduced to 7 days. Sunitinib dose and the number of days on therapy were individualised based on toxicity aiming for ≤ grade II toxicity with dose escalation in patients with minimal toxicity. The null hypothesis for the primary end-point was a progression-free survival (PFS) of 8.5 months based on a study with similar eligibility criteria. RESULTS: The null hypothesis was rejected (p < 0.001) with a median PFS of 12.5 months (95% confidence interval [CI]: 9.6-16.5). The median overall survival was 38.5 months (95% CI: 28.3-not reached). The objective response rate (46.1%) and stable disease rate (38.5%) translated into a clinical benefit for 84.6% of patients with no decline in quality of life scores during therapy. Fewer patients were dose reduced (26.5% vs. 50%) or discontinued due to toxicity (7.7 vs. 18-20%) compared to standard sunitinib dosing, and 20 (18.4%) patients were dose escalated to 62.5 mg (12) and 75 mg (8) with a wide individual variation in the optimal dose and treatment duration. CONCLUSIONS: Individualised sunitinib therapy is feasible, safe and an effective method to manage toxicity with one of the best efficacy seen for oral vascular endothelial growth factor inhibitors in metastatic renal cell carcinoma.

Purpose: To determine the safety, pharmacokinetics, and recommended phase II dose of an antibody-drug conjugate (ADC) targeting ectonucleotide phosphodiesterases-pyrophosphatase 3 (ENPP3) conjugated to monomethyl auristatin F (MMAF) in subjects with advanced metastatic renal cell carcinoma (mRCC).Patients and Methods: Two phase I studies were conducted sequentially with 2 ADCs considered equivalent, hybridoma-derived AGS-16M8F and Chinese hamster ovary-derived AGS-16C3F. AGS-16M8F was administered intravenously every 3 weeks at 5 dose levels ranging from 0.6 to 4.8 mg/kg until unacceptable toxicity or progression. The study was terminated before reaching the MTD. A second study with AGS-16C3F started with the AGS-16M8F bridging dose of 4.8 mg/kg given every 3 weeks.Results: The AGS-16M8F study (n = 26) closed before reaching the MTD. The median duration of treatment was 12 weeks (1.7-83 weeks). One subject had durable partial response (PR; 83 weeks) and 1 subject had prolonged stable disease (48 weeks). In the AGS-16C3F study (n = 34), the protocol-defined MTD was 3.6 mg/kg, but this was not tolerated in multiple doses. Reversible keratopathy was dose limiting and required multiple dose deescalations. The 1.8 mg/kg dose was determined to be safe and was associated with clinically relevant signs of antitumor response. Three of 13 subjects at 1.8 mg/kg had durable PRs (range, 100-143 weeks). Eight subjects at 2.7 mg/kg and 1.8 mg/kg had disease control >37 weeks (37.5-141 weeks).Conclusions: AGS-16C3F was tolerated and had durable antitumor activity at 1.8 mg/kg every 3 weeks.

Health-related quality of life (HRQoL) data are limited in patients with advanced basal cell carcinoma. To report HRQoL outcomes based on STEVIE (NCT01367665), a phase 2 study of vismodegib safety in patients with metastatic BCC or locally advanced BCC that is unsuitable for surgery or radiotherapy. Skindex-16 and MD Anderson Symptom Inventory (MDASI) questionnaires were completed at baseline and at three subsequent visits. Clinically meaningful improvement was defined as a ≥10-point decrease from baseline (Skindex-16) or improvement of at least 3 points from baseline (MDASI). HRQoL-evaluable patients with locally advanced BCC (n = 730) had ≥10-point improvements in Skindex-16 emotion domain scores at all time points. Changes in symptom and function scores in these patients or in any domain scores at any time point in patients with metastatic BCC (n = 10) were not clinically meaningful. Of 10 patients with symptomatic metastatic BCC at baseline, six had ≥3-point improvements in MDASI symptom severity. Skindex-16 and MDASI showed improvement in HRQoL in vismodegib-treated patients with locally advanced or metastatic BCC or BCC.

BACKGROUND: We hypothesized that changes in International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic category at start of second-line therapy (2L) for metastatic renal cell carcinoma (mRCC) might predict response. OBJECTIVE: To assess outcomes of 2L according to type of therapy and change in IMDC prognostic category. DESIGN, SETTING, AND PARTICIPANTS: We performed a retrospective review of the IMDC database for mRCC patients who received first-line (1L) VEGF inhibitors (VEGFi) and then 2L with VEGFi or mTOR inhibitors (mTORi). IMDC prognostic categories were defined before each line of therapy (favorable, F; intermediate, I; poor, P). Data were analyzed for 1516 patients, of whom 89% had clear cell histology. INTERVENTION: All included patients received targeted therapy for mRCC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Overall survival (OS), time to treatment failure, and response to 2L were analyzed using Cox or logistic regression. RESULTS AND LIMITATIONS: At start of 2L, 60% of patients remained in the same prognostic category; 9.0% improved (3% I â F; 6% P â I); 31% deteriorated (15% F â I or P; 16% I â P). Patients with the same or better IMDC prognostic category had a longer time to treatment failure if they remained on VEGFi compared to those who switched to mTORi (adjusted hazard ratio [AHR] ranging from 0.33 to 0.78, adjusted p<0.05). Patients who deteriorated from F to I appeared more likely to benefit from switching to mTORi (median OS 16.5 mo, 95% confidence interval [CI] 12.0-19.0 for VEGFi; 20.2 mo, 95% CI 14.3-26.1 for mTORi; AHR 1.53, 95% CI 1.04-2.24; adjusted p=0.03). CONCLUSIONS: Changes in IMDC prognostic category predict the subsequent clinical course for patients with mRCC and provide a rational basis for selection of subsequent therapy. PATIENT SUMMARY: The pattern of treatment failure might help to predict what the next treatment should be for patients with metastatic renal cell carcinoma.

BACKGROUND: The use of third-line targeted therapy (TTT) in metastatic renal cell carcinoma (mRCC) is not well characterized and varies due to the lack of robust data to guide treatment decisions. This study examined the use of third-line therapy in a large international population. OBJECTIVE: To evaluate the use and efficacy of targeted therapy in a third-line setting. DESIGN, SETTING, AND PARTICIPANTS: Twenty-five international cancer centers provided consecutive data on 4824 mRCC patients who were treated with an approved targeted therapy. One thousand and twelve patients (21%) received TTT and were included in the analysis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Patients were analyzed for overall survival (OS) and progression-free survival using Kaplan-Meier curves, and were evaluated for overall response. Cox regression analyses were used to determine the statistical association between OS and the six factors included in the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic model. Subgroup analysis was performed on patients stratified by their IMDC prognostic risk status. RESULTS AND LIMITATIONS: Everolimus was the most prevalent third-line therapy (27.5%), but sunitinib, sorafenib, pazopanib, temsirolimus, and axitinib were all utilized in over ≥9% of patients. Patients receiving any TTT had an OS of 12.4 mo, a progression-free survival of 3.9 mo, and 61.1% of patients experienced an overall response of stable disease or better. Patients not receiving TTT had an OS of 2.1 mo. Patients with favorable- (7.2%) or intermediate-risk (65.3%) disease had the highest OS with TTT, 29.9 mo and 15.5 mo, respectively, while poor-risk (27.5%) patients survived 5.5 mo. Results are limited by the retrospective nature of the study. CONCLUSIONS: TTT remains highly heterogeneous. The IMDC prognostic criteria can be used to stratify third-line patients. TTT use in favorable- and intermediate-risk patients was associated with the greatest OS. PATIENT SUMMARY: Patients with favorable- and intermediate-prognostic criteria disease treated with third-line targeted therapy have an associated longer overall survival compared with those with poor risk disease.

BACKGROUND: Prostate cancer that has recurred after local therapy or disseminated distantly is usually treated with androgen deprivation therapy; however, most men will eventually experience disease progression within 12 to 20 months. New data emerging from randomized controlled trials (RCTs) of chemotherapy provided the impetus for a systematic review addressing the following question: which non-hormonal systemic therapies are most beneficial for the treatment of men with hormone-refractory prostate cancer (HRPC) and clinical evidence of metastases? METHODS: A systematic review was performed to identify RCTs or meta-analyses examining first-line non-hormonal systemic (cytotoxic and non-cytotoxic) therapy in patients with HRPC and metastases that reported at least one of the following endpoints: overall survival, disease control, palliative response, quality of life, and toxicity. Excluded were RCTs of second-line hormonal therapies, bisphosphonates or radiopharmaceuticals, or randomized fewer than 50 patients per trial arm. MEDLINE, EMBASE, the Cochrane Library, and the conference proceedings of the American Society of Clinical Oncology were searched for relevant trials. Citations were screened for eligibility by four reviewers and discrepancies were handled by consensus. RESULTS: Of the 80 RCTs identified, 27 met the eligibility criteria. Two recent, large trials reported improved overall survival with docetaxel-based chemotherapy compared to mitoxantrone-prednisone. Improved progression-free survival and rates of palliative and objective response were also observed. Compared with mitoxantrone, docetaxel treatment was associated with more frequent mild toxicities, similar rates of serious toxicities, and better quality of life. More frequent serious toxicities were observed when docetaxel was combined with estramustine. Three trials reported improved time-to-disease progression, palliative response, and/or quality of life with mitoxatrone plus corticosteroid compared with corticosteroid alone. Single trials reported improved disease control with estramustine-vinblastine, vinorelbine-hydrocortisone, and suramin-hydrocortisone compared to controls. Trials of non-cytotoxic agents have reported equivocal results. CONCLUSION: Docetaxel-based chemotherapy modestly improves survival and provides palliation for men with HRPC and metastases. Other than androgen deprivation therapy, this is the only other therapy to have demonstrated improved overall survival in prostate cancer in RCTs. Further investigations to identify more effective therapies for HRPC including the use of systemic therapies earlier in the natural history of prostate cancer are warranted.

PURPOSE: Previous research has raised concerns that although salvage cryosurgery may be an effective treatment to prevent the progression of prostate cancer after radiotherapy failure, the quality of life cost many be so severe as to prevent its acceptance as a viable treatment. The present study's purpose was to further the understanding of the quality of life outcomes of salvage cryosurgery. MATERIALS AND METHODS: A total of 46 men with locally recurrent prostate cancer after radiotherapy were recruited to participate in a prospective Phase II clinical trial using salvage cryosurgery. There were 2 questionnaires (i.e., the European Organization of Research and Treatment of Cancer QLQ C30 and the Prostate Cancer Index) administered before cryosurgery, and at 1.5, 3, 6, 12, 18, and 24 months after treatment. RESULTS: Quality of life returned to preoperative levels by 24 months after cryosurgery in all domains, with the exception of urinary and sexual functioning. At 24 months, 29% of men reported urinary bother as a moderate-to-big problem, and 56% reported sexual bother as a moderate-to-big problem. CONCLUSIONS: To our knowledge, this is the first study to evaluate prospectively men's quality of life for 2 years after salvage cryosurgery for locally recurrent prostate cancer after radiotherapy. Long-term impairments in quality of life appear to be limited to the sexual and urinary function domains. Overall quality of life appears to be high. These results support salvage cryosurgery as a viable treatment option.
