The first-in-class hypoxia-inducible factor-2α (HIF-2α) inhibitor belzutifan is approved for patients with advanced renal cell carcinoma previously treated with immune checkpoint and anti-angiogenic therapy based on results of the phase 3 LITESPARK-005 trial. We present patient-reported outcomes (PROs) from LITESPARK-005. LITESPARK-005 was an open-label, multicentre, randomised, active-controlled phase 3 trial conducted at 147 hospitals and cancer centres in six regions. Eligible participants were 18 years or older with advanced clear cell renal cell carcinoma, had a Karnofsky Performance Status score of 70% or higher, had measurable disease per Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1, had disease progression on or after treatment with anti-PD-1 or anti-PD-L1 immunotherapy and a VEGF tyrosine kinase inhibitor (in sequence or in combination), and had received no more than three previous systemic lines of therapy. Eligible participants were randomly assigned (1:1) centrally using interactive voice-response and web-response systems to receive either belzutifan 120 mg orally once daily or everolimus 10 mg orally once daily. Randomisation was stratified by International Metastatic Renal Cell Carcinoma Database Consortium prognostic score and number of previous VEGF-targeted or VEGF receptor-targeted therapies. The dual primary outcomes were progression-free survival and overall survival, results of which have been reported previously. In this study, prespecified secondary patient-reported outcomes (PROs) from LITESPARK-005 were assessed using the Functional Assessment of Cancer Therapy-Kidney Cancer Symptom Index: Disease Related Symptoms (FKSI-DRS) and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). The PRO analysis population included all participants who received at least one dose of study therapy and completed at least one PRO assessment. Least-squares mean change from baseline in PROs at week 17 was assessed using a constrained longitudinal data analysis model. Time to deterioration in physical functioning (prespecified) and role functioning (post hoc), as assessed by the EORTC QLQ-C30, were also evaluated in the PRO analysis population. This trial is ongoing, closed to recruitment, and registered with ClinicalTrials.gov, NCT04195750. Between March 10, 2020, and Jan 19, 2022, 996 participants were screened for eligibility and 746 participants were randomly assigned to belzutifan (n=374) or everolimus (n=372). The PRO full analysis set population included 366 participants in the belzutifan group and 354 in the everolimus group. Median time from randomisation to the database cutoff date (June 13, 2023) was 25·7 months (IQR 21·7–30·4). Completion rates for FKSI-DRS and QLQ-C30 were higher than 94% at baseline and higher than 55% at week 17 in each group. Change from baseline to week 17 in FKSI-DRS score (difference in least-squares mean between groups 1·5 [95% CI 0·7 to 2·2]) and QLQ-C30 global health status–quality of life (QOL) score (6·4 [3·2 to 9·6]) suggested stability with belzutifan versus worsening with everolimus. Change from baseline to week 17 was similar between groups for QLQ-C30 physical functioning (difference in least-squares mean 2·5 [95% CI −0·6 to 5·5]) and QLQ-C30 role functioning (4·2 [0·1 to 8·4]) subscale scores. Time to deterioration was similar between the belzutifan and everolimus groups for EORTC physical functioning (median 19·3 months [95% CI 11·1 to not reached] in the belzutifan group vs 13·8 months [10·6 to not reached] in the everolimus group; hazard ratio 0·93 [95% CI 0·72 to 1·20]) and role functioning (median 12·0 months [9·2 to not reached] vs 10·2 months [4·7 to 14·4]; 0·88 [0·69 to 1·11]). Belzutifan for advanced renal cell carcinoma was associated with improved disease-specific symptoms and QOL compared with everolimus. Taken together with the efficacy and safety data from LITESPARK-005, belzutifan could offer a clinical benefit without compromising the QOL of patients in this setting.

A 47-year-old woman with a history of drug-resistant epilepsy during childhood presented to the emergency department with sudden dyspnea and chest pain. Upon admission, her oxygen saturation was 88%. A chest CT scan revealed pulmonary cystic lesions consistent with lymphangioleiomyomatosis and a right spontaneous pneumothorax, which resolved with the placement of a chest tube. Physical examination revealed a hypopigmented macule on the skin of the lumbar region, facial angiofibromas, and periungual fibromas. An abdominal MRI documented multiple bilateral renal tumors that were hypointense on T2-weighted imaging and showed a black boundary artifact, suggestive of fat-poor angiomyolipomas (AMLs). Subsequent percutaneous biopsy of the largest renal tumor confirmed the diagnosis of angiomyolipoma (positive for HMB-45 on immunohistochemistry). The brain MRI revealed subependymal nodules. The pulmonary function tests showed a mild obstructive pattern. Germline genetic testing confirmed the suspected diagnosis, and the patient started oral systemic treatment with everolimus (Afinitor) 10 mg once daily, along with dexamethasone rinses for prophylaxis.

Metastatic mature teratoma is a common radiologic and histopathologic finding after chemotherapy for metastatic non-seminomatous germ cell tumors. The leading theory for these residual tumors is the selective chemotherapy resistance of teratomas versus the high chemotherapy sensitivity of the embryonal components. Growing teratoma syndrome is a relatively rare phenomenon defined as an enlarging residual mass histologically proven to be a mature teratoma in the setting of normal serum tumor markers. Metastatic mature teratomas should be resected because of their malignant potential and occasional progression to growing teratoma syndrome with the invasion of the surrounding structures. CT is the preferred imaging modality for post-chemotherapy surveillance and should cover all sites of potential metastatic disease. This article reviews the clinical, pathologic, and multimodality imaging features of metastatic mature teratomas in patients with primary testicular non-seminomatous germ cell tumors.

A 56-year-old white man with a 74 pack-year smoking history presented with macroscopic hematuria and a significant weight loss of 45 pounds in 6 months. His clinical laboratory tests indicated iron defi ciency anemia and a computed tomography (CT) scan showed a left kidney tumor, mediastinal lymph nodes, and multiple lung metastases. A percutaneous CT-guided kidney biopsy revealed grade 3 clear cell renal carcinoma based on World Health Organization/International Society of Urologic Pathology classifi cation. The patient started first line systemic treatment for intermediate-risk metastatic renal cell carcinoma (mRCC) with combination immunotherapy with nivolumab plus ipilimumab.1 After 10 days of the first cycle, he presented with a pruritic maculopapular rash covering 20% of his body surface.A 56-year-old white man with a 74 pack-year smoking history presented with macroscopic hematuria and a significant weight loss of 45 pounds in 6 months.

BackgroundAlterations in the PTEN/PI3K/AKT/mTOR pathway are prevalent in prostate cancer. In this retrospective study, we evaluated the clinical effectiveness of mTOR inhibitors (mTORi) in patients with metastatic prostate cancer (mPCA) and tissue assessed phosphatidyl-3-inositol kinase (PI3K) pathway alterations.MethodsThis study used a nationwide (US-based) de-identified PCA clinico-genomic database, originating from approximately 280 US cancer clinics (~800 sites of care). We evaluated treatment data for patients with PCA from October 2014 to February 2020. In a cohort of 2301 PCA patients with 7208 evaluable treatment lines, we selected 17 mPCA patients (2 hormone-sensitive, 15 castrate-resistant) with tissue assessed PI3K pathway alterations by comprehensive genomic profiling who received mTORi treatment.ResultsPatients had a median age of 72 years (IQR 68.0, 76.0) and were heavily pretreated with a median 3 lines of therapy prior to mTORi use (range 0–6). The PI3K pathway alterations included PTENdel (10 patients, 58.8%), AKT1mut (4 patients, 23.5%), PTENmut (2 patients, 11.8%), and dual PTENmut and PIK3CAmut (1 patient, 5.9%). Most (15 patients, 88.2%) were treated with everolimus monotherapy. Among 10 patients with on treatment PSA available, 2 patients had a PSA decrease ≥10% at week 12 and 5 patients overall had a subsequent PSA decrease. For those on mTORi, the median time to next treatment was 3.62 months (range 0, 8.52).ConclusionsIn this small cohort of mPCA patients with tissue assessed PI3K pathway alterations, mTORi therapy was not effective with few PSA responses and short duration of therapy.

BackgroundThe advent of immune-checkpoint inhibitors has challenged previous treatment paradigms for advanced urothelial carcinoma (UC) in the post-platinum setting as well as in the first-line setting for cisplatin-ineligible patients. In this study, we investigated the effectiveness of pembrolizumab as first-line treatment for cisplatin-ineligible UC.MethodsData from patients aged ≥ 18 years with cisplatin-ineligible UC and receiving first-line pembrolizumab from January 1st 2017 to September 1st 2022 were collected. Cisplatin ineligibility was defined according to the Galsky criteria. Thirty-three Institutions from 18 countries were involved in the ARON-2 study.ResultsOur analysis included 162 patients. The median follow-up time was 18.9 months (95%CI 15.3–76.9). In the overall study population, the median OS was 15.8 months (95%CI 11.3–32.4). The median OS was significantly longer in males versus females while no statistically significant differences were observed between patients aged < 65y versus ≥ 65y and between smokers and non-smokers. According to Recist 1.1 criteria, 26 patients (16%) experienced CR, 32 (20%) PR, 39 (24%) SD and 55 (34%) PD.ConclusionsOur data confirm the role of pembrolizumab as first-line therapy for cisplatin-unfit patients. Further studies investigating the biological and immunological characteristics of UC patients are warranted in order to optimize the outcome of patients receiving immunotherapy in this setting.

Abstract Background ADXS31-142 is an attenuated Listeria monocytogenes-based immunotherapy targeting prostate-specific antigen (PSA), being evaluated as monotherapy and combined with pembrolizumab for metastatic castration-resistant prostate cancer (mCRPC). Patients and Methods The 2-part phase I/II KEYNOTE-046 study enrolled men with mCRPC who have progressed after 2 or fewer prior systemic treatment regimens in the metastatic setting. In Part A, intravenous ADXS31-142 monotherapy was given every 3 weeks (q3w) to 3 dose-escalation cohorts. In Part B, ADXS31-142 (1 × 109 colony-forming units) plus pembrolizumab (200 mg) was administered intravenously q3w for 3 doses with a fourth pembrolizumab dose 3 weeks later (12-week cycles) for up to 24 months or until progression/toxicity. Endpoints included safety, overall response rate, progression-free survival (PFS), overall survival (OS), and immunogenicity. Results Fifty patients received ADXS31-142 alone (n = 13) or with pembrolizumab (n = 37). Among the 37 RECIST-evaluable patients (n = 8 Part A; n = 29 Part B), there were no objective responses. Median PFS was 2.2 months (95% CI: 0.8-7.4) with monotherapy and 5.4 months (95% CI: 2.3-7.9) with the combination; median OS was 7.8 months (95% CI: 4.4-18.5) and 33.7 months (95% CI: 15.4–not evaluable), respectively. Promising OS benefit was observed in combination-treated patients who had received prior docetaxel (16.0 months, 95% CI: 6.4-34.6; n = 20) and those with visceral metastasis (16.4 months, 95% CI 4.0-not evaluable; n = 11). All patients had ≥1 treatment-related adverse event, mostly grade 1/2 manageable events. No additive toxicity was observed with combination treatment. Conclusions Combining ADXS31-142 with pembrolizumab was safe and well tolerated. The observed OS in mCRPC warrants further testing of this combination. Clinical Trial registration NCT02325557. The phase I/II KEYNOTE-046 trial evaluated the antitumor activity and safety of ADXS31-142 alone or in combination with pembrolizumab in patients with metastatic castration-resistant prostate cancer.

Purpose Oraxol is an oral formulation of paclitaxel administered with a novel, minimally absorbed P-glycoprotein inhibitor encequidar (HM30181A). This phase Ib study was conducted to determine the maximum-tolerated dose (MTD) of Oraxol administered at a fixed dose for up to 5 consecutive days in patients with advanced malignancies. Methods Part 1 of this study utilized a 3 + 3 dose-escalation design to determine the MTD of oral paclitaxel 270 mg plus oral encequidar 15 mg administered daily. Dose escalation was achieved by increasing the number of consecutive dosing days per week (from 2 to 5 days per week). Dosing occurred for 3 consecutive weeks out of a 4-week cycle. Part 2 treated additional patients at the MTD to determine tolerability and recommended phase II dose (RP2D). Adverse events, tumor responses, and pharmacokinetic profiles were assessed. Results A total of 34 patients ( n  = 24 in Part 1, n  = 10 in Part 2) received treatment. The MTD of Oraxol was determined to be 270 mg daily × 5 days per week per protocol definition and this was declared the RP2D. The most common treatment-related adverse events were fatigue, neutropenia, and nausea/vomiting. Hypersensitivity-type reactions were not observed. Of the 28 patients evaluable for response, 2 (7.1%) achieved partial response and 18 (64.3%) achieved stable disease. Pharmacokinetic analysis showed rapid absorption of paclitaxel when administered orally following encequidar. Paclitaxel daily exposure was comparable following 2–5 days dose levels. Conclusion The oral administration of encequidar with paclitaxel was safe, achieved clinically relevant paclitaxel levels, and showed evidence of anti-tumor activity.

Background: Patients with advanced chronic kidney disease (ACKD) are at an increased risk of developing renal cell carcinoma (RCC), but molecular alterations in RCC specimens arising from ACKD and overall survival (OS) in affected patients are not well defined. Patients and Methods: Using the Oncology Research Information Exchange Network (ORIEN) Total Cancer Care® protocol, 296 consented adult patients with RCC and somatic tumor whole exome sequencing were included. Patients with ACKD were defined as those with serum creatinine ≥1.5 mg/dL prior to RCC diagnosis. Results: Of 296 patients with RCC, 61 met the criteria for ACKD. The most common somatic mutations in the overall cohort were in VHL (126, 42.6%), PBRM1 (102, 34.5%), and SETD2 (54, 18.2%). BAP1 had a decreased mutational frequency in RCC specimens from patients without ACKD as compared to those with ACKD (10.6% versus 1.6%), but this was not statistically significant in univariable (OR 0.14, p = 0.056) or multivariable (OR 0.15, p = 0.067) analysis. Median OS was not reached in either cohort. Conclusions: Using the clinicogenomic ORIEN database, our study found lower rates of BAP1 mutations in RCC specimens from patients with ACKD, which may reflect a BAP1-independent mutational driver of RCC in patients with ACKD.

Circadian rhythm regulates cellular differentiation and physiology and shapes the immune response. Altered expression of clock genes might lead to the onset of common malignant cancers, including Renal Cell Carcinoma (RCC). Data from Cancer Genome Atlas (TCGA) indicate that clock genes PER1-3, CRY2, CLOCK, NR1D2 and RORα are overexpressed in RCC tissues and correlate with patients’ prognosis. The expression of clock genes could finely tune transcription factor activity in RCC and is associated with the extent of immune cell infiltration. The clock system interacts with hypoxia-induced factor-1α (HIF-1α) and regulates the circadian oscillation of mammalian target of rapamycin (mTOR) activity thereby conditioning the antitumor effect of mTOR inhibitors. The stimulation of natural killer (NK) cell activity exerted by the administration of interferon-α, a cornerstone of the first era of immunotherapy for RCC, relevantly varies according to circadian dosing time. Recent evidence demonstrated that time-of-day infusion directly affects the efficacy of immune checkpoint inhibitors in cancer patients. Compounds targeting the circadian clock have been identified and their role in the era of immunotherapy deserves to be further investigated. In this review, we aimed at addressing the impact of clock genes on the natural history of kidney cancer and their potential therapeutic implications.
