RESUMO
Background: The treatment of heavily pretreated patients with metastatic renal cell carcinoma (mRCC) represents an unmet medical need and is still challenging. Objectives: The primary objective was to assess the effectiveness of the lenvatinib plus everolimus combination and the secondary objective was the toxicity profile of this combination. Design: We conducted a longitudinal retrospective study examining mRCC patients pre-treated with one or more lines of therapy among different cancer centers in Italy. Methods: The study included patients who received the combination of lenvatinib plus everolimus as either a second-line treatment or beyond. We assessed progression-free survival (PFS), time to treatment failure (TTF), overall survival (OS), response rate (RR), and toxicity profile. In addition, we explored the potential relationship between treatment effectiveness and clinical and laboratory parameters. Results: In all, 33 patients were assessed, the median age was 60 years, 57% had an Eastern Cooperative Oncology Group performance status of 1-2 and. 63% received ⩾ 3 prior lines of therapy. 62% were 'intermediate risk' according to the International Metastatic Renal Cell Carcinoma Database Consortium and 30% were 'poor risk'. The RR was 42% (no complete response), 18% stable disease. Median OS was 11.2 months (95% CI 6.8-19.9), median PFS was 6.7 months (95% CI 0.6-30.8), and median TTF was 6.7 months (95% CI 4.8-16.6). A shorter OS was significantly associated with lymph node metastases (p = 0.043, 95% CI), neutrophils/ lymphocytes ratio (NLR) ⩾ 3 (p = 0.007), hemoglobin/red cell distribution width ratio cutoff value <0.7 was significant (p = 0.03) while a shorter PFS was associated with lung (p = 0.048) and brain metastases (p = 0.023). The most frequent G1 toxicity was diarrhea (24%), G2 was fatigue (30%), and hypertension and skin toxicity (6%) for G3. Conclusion: Our findings suggest a clinically relevant effectiveness of lenvatinib plus everolimus combination with an acceptable toxicity profile for heavily pretreated patients with mRCC.
RESUMO
INTRODUCTION: Penile squamous cell carcinoma (PSCC) is a rare tumor with an aggressive behavior. The Meet-URO 23/I-RARE registry includes rare genitourinary malignancies. We extracted patients with PSCC to conduct a retrospective study aimed at assessing clinical outcomes and prognostic factors. PATIENTS AND METHODS: Primary endpoints were overall survival and progression-free survival. Prognostic factors for OS and PFS were analyzed using univariate and multivariate analysis. From the Meet-URO 23/I-RARE database, we extracted 128 patients with diagnosis of PSCC. About 48% of patients underwent first-line of therapy. RESULTS: In the overall population, median OS from diagnosis was 34.6 months. Significant differences in median OS were observed according to ECOG PS at diagnosis (57.3 months vs. 8.3 months; P < .001), and median age (≤77y 88.8 months vs. >77y 26 months; P = .013). At multivariate analysis, ECOG PS 2-4 at diagnosis (HR 3.04) and lymph node metastases (HR 2.49) were independently associated with a higher risk of death. Among patients undergoing first-line therapy (n = 61), median OS was 12.3 months, and a statistically significant difference was found according to type of response to first-line (DCR 24.4 months vs. PD 7.1 months; P < .001). Multivariate analysis showed that only age >77 years was associated with a worse OS (HR 2.16). A statistically significant difference in PFS was found according to platinum plus 5-fluorouracil versus platinum plus taxane (4.9 vs. 3.4 months; P = .036) and regimens with 2 versus 3 drugs (3.4 vs. 8.6 months; P = .019). At the multivariate analysis only regimens with platinum plus taxane were associated with worse PFS (HR 2.83). CONCLUSION: In our registry study, PSCC is confirmed to be an aggressive disease. Poor ECOG PS, presence of lymph node metastases, and higher age at diagnosis appear to be associated with worse survival outcomes.

BACKGROUND: Peritoneal metastases (PM) have been reported in approximately 1% of patients with metastatic Renal Cell Carcinoma (mRCC). Outcome data are limited due to the rarity of this metastatic site. Therefore, the aim of our study is to describe renal cell carcinoma (RCC) patients with PM treated as per clinical practice. MATERIALS AND METHODS: Baseline characteristics and outcome data of patients with PM from RCC were retrospectively collected from 18 Italian oncological referral centers adhering to the Meet-Uro group, from January 2016 to January 2023. RESULTS: We collect 81 RCC patients with PM. 78/81 received systemic treatment, 3/81 only best supportive care. First line treatment included tyrosine-kinase inhibitors (TKI) (46/78), ImmuneOncology (IO)-TKI (26/78) and IO-IO (6/78), with different Objective Response Rate (ORR) (43.4% in TKI monotherapy group vs 50% in IO-TKI group, respectively) and Disease Control Rate (DCR) (60.8% in TKI treated patients vs. 76.9% in IO-TKI treated patients). Median PFS was 6.4 months (95%CI 4.18-14.8) in patients treated with TKI monotherapy vs 23.7 months (95%CI 11.1-NR) in patients treated with IO-TKI (p < 0.015). The median OS (mOS) was 22.7 months (95%CI 13.32 - 64.7) in the TKI monotherapy group vs 34.5 mo (95%CI NR-NR) in the IO-TKI group with 53.8% of patients alive at 1 years in the latter group, (p < 0.16). Primary refractory patients were 36.9% for TKI and 15.3% for IO-TKI. According to International Metastatic renal cell carcinoma Database Consortium (IMDC) score, mPFS and mOS were consistent among risk categories. Median PFS was 36.6 months (95%CI 10.9-NR) for good risk patients compared to 10 months (95%CI 7.5-29.8) for intermediate risk and 2.96 months (95%CI 2.43-11.28) for poor risk population (p < 0.0005) whereas mOS was NR (95%CI 28.65-NR) for good risk patients compared to 35.3 months (95%CI 24.6-NA) and 12.4 months (95%CI 3.52-NR) for intermediate and poor risk population, respectively, (p < 0.0002). Only 34/78 (43.5%) received a second line treatment that was TKI (ORR 8.3% and DCR 41.6%) or IO (ORR 18.1% and DCR 40.9%). CONCLUSION: We report one of the largest case series regarding PM from RCC. Characteristics of patients suggest a more aggressive behavior of PM from mRCC. Outcome data suggest that TKI-IO as first line treatment, and TKI as second line, confirm their activity for these patients with dismal prognosis.

BACKGROUND: Renal c carcinoma (RCC) is one of the most common urinary cancers worldwide, with a predicted increase in incidence in the coming years. Immunotherapy, as a single agent, in doublets, or in combination with anti-vascular endothelial growth factor receptor tyrosine kinase inhibitors (TKIs), has rapidly become a cornerstone of the RCC therapeutic scenario, but no head-to-head comparisons have been made. In this setting, real-world evidence emerges as a cornerstone to guide clinical decisions. OBJECTIVE: The objective of this retrospective study was to assess the outcome of patients treated with first-line immune combinations or immune oncology (IO)-TKIs for advanced RCC. DESIGN, SETTING, AND PARTICIPANTS: Data from 930 patients, 654 intermediate risk and 276 poor risk, were collected retrospectively from 58 centers in 20 countries. Special data such as sarcomatoid differentiation, body mass index, prior nephrectomy, and metastatic localization, in addition to biochemical data such as hemoglobin, platelets, calcium, lactate dehydrogenase, neutrophils, and radiological response by investigator's criteria, were collected. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method. The median follow-up was calculated by the inverse Kaplan-Meier method. RESULTS AND LIMITATIONS: The median follow-up time was 18.7 mo. In the 654 intermediate-risk patients, the median OS and PFS were significantly longer in patients with the intermediate than in those with the poor International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) criteria (38.9 vs 17.3 mo, 95% confidence interval [CI] p < 0.001, and 17.3 vs 11.6 mo, 95% CI p < 0.001, respectively). In the intermediate-risk subgroup, the OS was 55.7 mo (95% CI 31.4-55.7) and 40.2 mo (95% CI 29.6-51.6) in patients treated with IO + TKI and IO + IO combinations, respectively (p = 0.047). PFS was 30.7 mo (95% CI 16.5-55.7) and 13.2 mo (95% CI 29.6-51.6) in intermediate-risk patients treated with IO + TKI and IO + IO combinations, respectively (p < 0.001). In the poor-risk subgroup, the median OS and PFS did not show a statistically significant difference between IO + IO and IO + TKI. Our study presents several limitations, mainly due to its retrospective nature. CONCLUSIONS: Our results showed differences between the IO + TKI and IO + IO combinations in intermediate-risk patients. A clear association with longer PFS and OS in favor of patients who received the IO + TKI combinations compared with the IO-IO combination was observed. Instead, in the poor-risk group, we observed no significant difference in PFS or OS between patients who received different combinations. PATIENT SUMMARY: Renal cancer is one of the most frequent genitourinary tumors. Treatment is currently based on immunotherapy combinations or immunotherapy with tyrosine kinase inhibitors, but there are no comparisons between these.In this study, we have analyzed the clinical course of 930 patients from 58 centers in 20 countries around the world. We aimed to analyze the differences between the two main treatment strategies, combination of two immunotherapies versus immunotherapy + antiangiogenic therapy, and found in real-life data that intermediate-risk patients (approximately 60% of patients with metastatic renal cancer) seem to benefit more from the combination of immunotherapy + antiangiogenic therapy than from double immunotherapy. No such differences were found in poor-risk patients. This may have important implications in daily practice decision-making for these patients.

BACKGROUND: The addition of neutrophil to lymphocyte ratio (NLR) and bone metastases to the IMDC classification provided by the Meet-URO score, resulted in higher prognostic accuracy in metastatic renal cell carcinoma (mRCC) patients receiving ≥2nd line nivolumab or cabozantinib in 2 retrospective analyses and 1st line nivolumab-ipilimumab in an expanded access programme. Prognostic estimates for older mRCC patients might be key for clinical decision-making. METHODS: The outcome of real-world older (≥70 years) mRCC patients treated with any line cabozantinib within the multicenter observational prospective ZEBRA (Meet-URO 9) study was analyzed according to the baseline Meet-URO score. The primary endpoint was overall survival (OS). The discriminative ability by Harrell's c-index and calibration were assessed to compare the Meet-URO and IMDC scores. RESULTS: A total of 104 mRCC patients received cabozantinib as 1st (38%), 2nd (20%), or ≥3rd (41%) line. With a median follow-up of 11.2 months, the median OS (mOS) was of 18.4 months. According to the IMDC score, favorable (15%), intermediate (65%) and poor-risk (19%) patients had a mOS not reached, of 15.6 and 5.7 months respectively (p = .011). According to the Meet-URO score groups, mOS was not reached in both group 1 (10%) and group 2 (25%), while in group 3 (33%), group 4 (25%) and group 5 (8%) mOS was of 13.6, 12.5, and 3.7 months, respectively (p < .001). The discriminative ability of the Meet-URO score was maintained by merging groups 1 to 2 vs. 3 to 4 vs. 5 (p < .001). The Meet-URO score (with either the original 5-group stratification or the modified 3-group one) showed higher accuracy than the IMDC score (c-index of 0.686 and 0.676 vs. 0.622). CONCLUSION: This analysis confirmed the prognostic accuracy of the Meet-URO score in older mRCC patients treated with cabozantinib and its role as a convenient tool for informing the patient and clinical decisions.

BACKGROUND: The upfront treatment of metastatic renal cell carcinoma (mRCC) has been revolutionized by the introduction of immune-based combinations. The role of cytoreductive nephrectomy (CN) in these patients is still debated. The ARON-1 study (NCT05287464) was designed to globally analyze real-world data of mRCC patients receiving first-line immuno-oncology combinations. This sub-analysis is focused on the role of upfront or delayed partial or radical CN in three geographical areas (Western Europe, Eastern Europe, America/Asia). METHODS: We conducted a multicenter retrospective observational study in mRCC patients treated with first-line immune combinations from 55 centers in 19 countries. From 1152 patients in the ARON-1 dataset, we selected 651 patients with de novo mRCC. 255 patients (39%) had undergone CN, partial in 14% and radical in 86% of cases; 396 patients (61%) received first-line immune-combinations without previous nephrectomy. RESULTS: Median overall survival (OS) from the diagnosis of de novo mRCC was 41.6 months and not reached (NR) in the CN subgroup and 24.0 months in the no CN subgroup, respectively (P<0.001). Median OS from the start of first-line therapy was NR in patients who underwent CN and 22.4 months in the no CN subgroup (P<0.001). Patients who underwent CN reported longer OS compared to no CN in all the three geographical areas. CONCLUSIONS: No significant differences in terms of patients' outcome seem to clearly emerge, even if the rate CN and the choice of the type of first-line immune-based combination varies across the different Cancer Centers participating in the ARON-1 project.

BACKGROUND: Immune-Oncology (IO) improves Overall Survival (OS) in metastatic Renal Cell Carcinoma (mRCC). The prognostic impact of previous Cytoreductive Nephrectomy (CN) and radical nephrectomy (RN), with curative intent, in patients treated with IO is not well defined. The aim of our paper is to evaluate the impact of previous nephrectomy on outcome of mRCC patients treated with IO. METHODS: 287 eligible patients were retrospectively collected from 16 Italian referral centers adhering to the MeetUro association. Patients treated with IO as second and third line were included, whereas patients treated with IO as first line were excluded. Kaplan-Meier method and log-rank test were performed to compare Progression Free Survival (PFS) and OS between groups. In our analysis, both CN and RN were included. The association between nephrectomy and other variables was analyzed in univariate and multivariate setting using the Cox proportional hazard model. RESULTS: 246/287 (85.7%) patients had nephrectomy before IO treatment. Median PFS in patients who underwent nephrectomy (246/287) was 4.8 months (95%CI 3.9-5.7) vs 3.7 months (95%CI 1.9-5.5) in patients who did not it (HR log rank 0.78; 95%CI 0.53 to 1.15; p = 0.186). Median OS in patients who had previous nephrectomy (246/287) was 20.9 months (95%CI 17.6-24.1) vs 13 months (95%CI 7.7-18.2) in patients who did not it (HR log rank 0.504; 95%CI 0.337 to 0.755; p = 0.001). In the multivariate model, nephrectomy showed a significant association with OS (HR log rank 0.638; 95%CI 0.416 to 0.980), whereas gland metastases were still associated with better outcome in terms of both OS (HR log rank 0.487; 95%CI 0.279 to 0.852) and PFS (HR log rank 0.646; 95%CI 0.435 to 0.958). CONCLUSIONS: IO treatment, in patients who had previously undergone nephrectomy, was associated with a better outcome in terms of OS. Further prospective trials would assess this issue in order to guide clinicians in real word practice.
RESUMO
OBJECTIVES: The aim of our study was to collect data about of the outcome of metastatic renal cell carcinoma patients who progressed after immune checkpoint inhibitors in order to enhance data about efficacy and safety of treatment beyond immune-oncology (IO). MATERIALS AND METHODS: A total of 162 eligible patients, progressing to IO, were enrolled from 16 Italian referral centers adhering to the Meet-Uro association. Baseline characteristics, outcome data and toxicities were retrospectively collected. Descriptive analysis was made using median values and ranges. Kaplan-Meier method and Mantel-Haenszel log-rank test were performed to compare differences between groups. RESULTS: A total of 111 patients (68.5%) were treated after IO progression. In all, 51 patients (31.5%) did not receive further treatment for clinical deterioration. Median IO progression free survival (PFS) was 4 months (95% confidence interval [CI]: 3.1-4.8). IO-PFS tends to be longer in patients reporting adverse events (AE) of any grade (5.03 [95% CI: 3.8-6.1] vs. 2.99 [95% CI: 2.4-3.5] months P=0.004). Subsequent therapies included cabozantinib (n=79, 48%), everolimus (n=11, 6.7%), and others (n=21, 12.9%).Median PFS post-IO was 6.5 months (95% CI: 5.1-7.8). Cabozantinib showed longer PFS compared with everolimus (7.6 mo [95% CI: 5.2-10.1] vs. 3.2 mo [95% CI: 1.8-4.5]) (hazard ratio: 0.2; 95% CI: 0.1026-0.7968) and other drugs (4.3 mo [95% CI: 1.3-7.4]) (hazard ratio: 0.6; 95% CI: 0.35-1.23). All grade AE were reported in 83 patients (74%) and G3 to G4 AE in 39 patients (35%). Target therapies post-IO showed median overall survival of 14.7 months (95% CI: 0.3-21.4). CONCLUSIONS: In our real world experience after progression to IO, vascular endotelial groth factor-tyrosine kinase inhibitors, given to patients, proved to be active and safe choices. Cabozantinib was associated with a better outcome in terms of median PFS.

BACKGROUND: This multi-institutional retrospective real life study was conducted in 22 Italian Oncology Centers and evaluated the role of Axitinib in second line treatment in not selected mRCC patients. METHODS: 148 mRCC patients were evaluated. According to Heng score 15.5%, 60.1% and 24.4% of patients were at poor risk, intermediate and favorable risk, respectively. RESULTS: PFS, OS, DCR and ORR were 7.14 months, 15.5 months, 70.6% and 16.6%, respectively. The duration of prior sunitinib treatment correlated with a longer significant mPFS, 8.8 vs 6.3 months, respectively. Axitinib therapy was safe, without grade 4 adverse events. The most frequent toxicities of all grades were: fatigue (50%), hypertension (26%), and hypothyroidism (18%). G3 blood pressure elevation significantly correlated with longer mPFS and mOS compared to G1-G2 or no toxicity. Dose titration (DT) to 7 mg and 10 mg bid was feasible in 24% with no statistically significant differences in mPFS and mOS. The sunitinib-axitinib sequence was safe and effective, the mOS was 41.15 months. At multivariate analysis, gender, DCR to axitinib and to previous sunitinib correlated significantly with PFS; whereas DCR to axitinib, nephrectomy and Heng score independently affected overall survival. CONCLUSIONS: Axitinib was effective and safe in a not selected real life mRCC population. Trial registration INT - Napoli - 11/16 oss. Registered 20 April 2016. http://www.istitutotumori.na.it.

Taxane-related peripheral neuropathy (TrPN) is a dose-limiting toxicity with important interindividual variability. Genetic polymorphisms in absorption, distribution, metabolism, and excretion (ADME) genes may account for variability in drug efficacy and/or toxicity. By the use of Affymetrix drug-metabolizing enzyme and transporter microarray platform, in a retrospective case-control study, the correlation between ADME polymorphic variants and grades ≥ 2-3-TrPN was investigated. In a breast cancer (BC) training set, five single-nucleotide polymorphisms in NR1I3 and UDP-glucuronosyltransferase (UGT)2B7 genes were correlated to grades ≥ 2-3-TrPN protection. By receiver operating characteristic curves, the grades ≥ 2-3-TrPN-related candidate biomarkers in an independent series of 54 patients with BC (17 cases and 37 controls) were validated. NR1I3 was correlated to paclitaxel-TrPN and UGT2B7 to docetaxel-TrPN. Moreover, a genetic signature of prognostic relevance for BC outcome was found. Our findings might have potential relevance for personalized management of patients with BC for prevention of treatment failure in ultrametabolizer genetic variants.

INTRODUCTION: Carboplatin is the milestone of epithelial ovarian cancer (EOC) treatment, thus response to platinum is the major prognostic factor. Among platinum-sensitive patients, 40% carry a germline or somatic BRCA1/2 mutation. In this scenario a new class of drugs, the PARP inhibitors (PARPis), produced a significant improvement in long-term disease control. In order to make an aggregate evaluation of the impact of these agents, we performed a systematic review and meta-analysis. PATIENTS AND METHODS: Clinical trials were selected by searching "Pubmed" database and abstracts from major cancer meetings. We considered the January 2008 - April 2018 time frame. Progression free survival (PFS) was the primary end-point, toxicities were secondary end-points. Hazard ratios (HRs) of PFS, with confidence intervals, and risk ratios of grade 3-4 toxicity rates, were extracted from retrieved studies and included in the current analysis. Meta-analysis was carried out by the fixed and random effect models. We conducted this meta-analysis to also compare indirectly the efficacy of different PARPis in EOC patients. RESULTS: Five randomized trials for a total of 1839 patients were selected and included in the final analysis. In particular, we evaluated a BRCA-mutant cohort (871 patients) with a pooled HR 0.25 (95%CI 0.21-0.31) and the BRCA-wild type cohort (836 patients) with a pooled HR 0.41 (95%CI 0.31-0.55), respectively. Regarding safety profile, no significant differences were detected in all grade toxicities, however, taking into account 3-4 grade toxicities and SAEs (severe adverse events), we show that rucaparib-treated patients reported major abdominal pain events, while niraparib-treated patients were associated with the highest percentage of haematological toxicities, hypothesizing a drug effect for the safety analysis. In the indirect comparisons, significant differences were not detected on PFS for the different agents. CONCLUSIONS: We confirm a significant benefit in survival outcome of PARPis for EOC patients with a "class effect" on the bases of narrow CI and indirect comparisons in the different groups. Therefore, we underline that this strategy is of special value in BRCA-mutated patients because genetic testing allows best patient selection for all PARPis with the added value of individualized prevention in familiars.

Axitinib is an oral angiogenesis inhibitor, currently approved for treatment of metastatic renal cell carcinoma (mRCC) after failure of prior treatment with Sunitinib or cytokine. The present study is an Italian Multi-Institutional Retrospective Analysis that evaluated the outcomes of Axitinib, in second-line treatment of mRCC. The medical records of 62 patients treated with Axitinib, were retrospectively reviewed. The Progression Free Survival (PFS), the Overall Survival (OS), the Objective Response Rate (ORR), the Disease Control Rate (DCR), and the safety profile of axitinib and sunitinib-axitinib sequence, were the primary endpoint. The mPFS was 5.83 months (95% CI 3.93-7.73 months). When patients was stratified by Heng score, mPFS was 5.73, 5.83, 10.03 months according to poor, intermediate, and favorable risk group, respectively. The mOS from the start of axitinib was 13.3 months (95% CI 8.6-17.9 months); the observed ORR and DCR were 25 and 71%, respectively. When stratified patients by subgroups defined by duration of prior therapy with Sunitinib (≤ vs. >median duration), there was a statistically significant difference in mPFS with 8.9 (95% CI 4.39-13.40 months) vs. 5.46 months (95% CI 4.04-6.88 months) for patients with a median duration of Sunitinib >13.2 months. DCR and ORR to previous Sunitinib treatment was associated with longer statistically mPFS, 7.23 (95% CI 3.95-10.51 months, p = 0.01) and 8.67 (95% CI 4.0-13.33 months, p = 0.008) vs. 2.97 (95% CI 0.65-5.27 months, p = 0.01) and 2.97 months (95% CI 0.66-5.28 months, p = 0.01), respectively. Overall Axitinib at standard schedule of 5 mg bid, was well-tolerated. The most common adverse events of all grades were fatig (25.6%), hypertension (22.6%), gastro-intestinal disorders (25.9%), and hypothyroidism (16.1%). The sequence Sunitinib-Axitinib was well-tolerated without worsening in side effects, with a median OS of 34.7 months (95% CI 18.4-51.0 months). Our results are consistent with the available literature; this retrospective analysis confirms that Axitinib is effective and safe in routine clinical practice.
RESUMO
OBJECTIVE: A combination regimen of temozolomide (TMZ) and pegylated liposomal doxorubicin has been evaluated in the treatment of brain metastases from solid tumours. STUDY DESIGN: Nineteen consecutive patients (pts) have been enrolled in a prospective phase II trial and treated with TMZ 200 mg/m2 (days 1-5) and pegylated liposomal doxorubicin 35 mg/m2 (day 1) every 28 days. The study was prospectively projected according to the Simon's two-stage optimal design. RESULTS: Major toxicities have been grade III neutropenia and thrombocytopenia in one patient (pt) and grade III erythrodisesthesia in two pts. Three pts achieved a complete response (CR) and four a partial response (PR), for an overall response rate of 36.8% (95% CI: 19.1-59.2), which exceeded the target activity in the study design. A significant improvement in quality of life was demonstrated by FACT-G analysis. The median Progression Free Survival (PFS) was 5.5 (95% CI: 2.7-8.2) months while the median Overall Survival (OS) was 10.0 months (95% CI: 6.3-13.7). CONCLUSIONS: The TMZ/pegylated liposomal doxorubicin regimen was well tolerated with an encouraging activity in brain metastases from solid tumours.
