Long-term responders to nivolumab in previously treated advanced renal cell carcinoma: a sub-analysis of meet-URO15 study.

BACKGROUND: Although nivolumab prolongs overall survival (OS) in pretreated patients with metastatic renal cell carcinoma (mRCC), underlining clinical and biological features of long-term responses are still to be determined. This study aims to investigate clinical and pathological characteristics of mRCC patients who achieved long-term responses during nivolumab treatment. MATERIALS AND METHODS: A retrospective analysis was performed on mRCC patients receiving nivolumab as second or further therapy line between May 2016 and January 2019 in 34 Italian Oncology Centres. Outcome assessments and logistic regression were performed to evaluate factors influencing long-term responses. RESULTS: A total of 571 patients with a median age of 61 years (range 17-85) were included in the analysis. With a median follow-up of 22.1 (1.0-89.0) months, 23.1% of patients were 2-year progression-free on treatment with nivolumab, hence they were categorized as long-term responders. Baseline characteristics, including age, gender, and histology, were similar between long- and short-term responders. Karnofsky Performance Status ≥ 80% was significantly associated with long-term response (p = 0.02), while bone metastases (p = 0.03), International mRCC Database Consortium intermediate-poor risk (p < 0.01) and Neutrophil-to-Lymphocyte Ratio ≥ 3.2 (p = 0.02) were associate with short-term responses. Long-term responders exhibited a median progression-free survival of 55.0 months versus 4.0 months of the short-term responders. The median OS was not reached in long-term responders while it was 17.0 months for short*term responders. CONCLUSION: This retrospective analysis sheds light on factors associated with long-term response to nivolumab in mRCC. Understanding these clinical features will be essential for selecting patients who may mostly benefit from immunotherapy.

Analyses of tumor microenvironment in patients with advanced renal cell carcinoma receiving immunotherapy (Meet-URO 18 study).

Introduction: The Meet-URO 18 study is a multicentric study of patients with metastatic renal cell carcinoma receiving nivolumab in the second-line and beyond, categorized as responders (progression-free survival ≥ 12 months) and non-responders (progression-free survival < 3 months). Areas covered: The current study includes extensive immunohistochemical analysis of T-lineage markers (CD3, CD4, CD8, CD8/CD4 ratio), macrophages (CD68), ph-mTOR, CD15 and CD56 expression on tumor cells, and PD-L1 expression, on an increased sample size including 161 tumor samples (113 patients) compared with preliminary presented data. Responders' tumor tissue (n = 90; 55.9%) was associated with lower CD4 expression (p = 0.014), higher CD56 expression (p = 0.046) and higher CD8/CD4 ratio (p = 0.030). Expert opinion/commentary: The present work suggests the regulatory role of a subpopulation of T cells on antitumor response and identifies CD56 as a putative biomarker of immunotherapy efficacy.

Fracture risk and survival outcomes in metastatic castration-resistant prostate cancer patients sequentially treated with abiraterone acetate and RADIUM-223.

PURPOSE: To evaluate the fracture risk and survival outcomes in patients with metastatic castration-resistant prostate cancer (mCRPC) who received sequentially abiraterone acetate (AA) and radium 223 [223Ra]RaCl2 in the daily clinical practice. MATERIALS: We retrospectively reviewed the records of mCRPC patients who received [223Ra]RaCl2 immediately after progressing during an AA treatment line in everyday clinical practice. RESULTS: We reviewed data of a consecutive series of 94 mCRPC patients. Most of the patients (85.1%) received [223Ra]RaCl2 as second- or third-line treatment. [223Ra]RaCl2 treatment was well-tolerated; there were only four cases of grade 3 anaemia, two cases of grade 3 leukopenia and one case of grade 3 neutropenia. The overall fracture rate is 2.1%; one fracture was recorded during the course of [223Ra]RaCl2 treatment, and one was recorded 1 month after its end. The fractures both occurred at metastatic sites. Median OS from [223Ra]RaCl2 start was more than 14 months regardless of the treatment line when [223Ra]RaCl2 was administered. CONCLUSION: The findings of this study show that the treatment with [223Ra]RaCl2 immediately after AA was active and safe with a very low risk of a fracture. Thus, the present observational report makes a valuable contribution to the current debate concerning the risks and benefits of including [223Ra]RaCl2 in the therapeutic algorithm.

The outcome to axitinib or everolimus after sunitinib in metastatic renal cell carcinoma.

We aimed to investigate the different outcomes in patients with metastatic renal cell carcinoma treated with second-line axitinib or everolimus after sunitinib. Patients treated in 16 oncological centres in Italy were included, and those receiving axitinib or everolimus from January 2013 onwards were analysed for outcomes. Descriptive statistical tests were used to highlight differences between groups. The Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Data on 634 patients with metastatic renal cell carcinoma treated with first-line sunitinib have been obtained. A total of 182 patients received a second-line therapy with everolimus (79 patients, 43%) or axitinib (103 patients, 57%), respectively. The median PFS was 4.6 [95% confidence (CI): 2.6-6.5] months for patients treated with everolimus and 5.5 (95% CI: 4.3-6.7) months for patients treated with axitinib (P=0.7). The median OS was 13.9 (95% CI: 10.4-17.4) months for patients treated with everolimus and 12.0 (95% CI: 7.9-16.2) months for patients treated with axitinib (P=0.3). No differences were found based on length of first-line treatment. Major limitations are the retrospective nature of the study and the lack of a prospective evaluation of the progression. This study reports no significantly differences between everolimus and axitinib in terms of both PFS and OS. Furthermore, the length of first-line treatment cannot be used as such a predictive factor and cannot suggest the use of a molecule compared with another.

Contrast-enhanced spectral mammography in neoadjuvant chemotherapy monitoring: a comparison with breast magnetic resonance imaging.

BACKGROUND: Neoadjuvant-chemotherapy (NAC) is considered the standard treatment for locally advanced breast carcinomas. Accurate assessment of disease response is fundamental to increase the chances of successful breast-conserving surgery and to avoid local recurrence. The purpose of this study was to compare contrast-enhanced spectral mammography (CESM) and contrast-enhanced-MRI (MRI) in the evaluation of tumor response to NAC. METHODS: This prospective study was approved by the institutional review board and written informed consent was obtained. Fifty-four consenting women with breast cancer and indication of NAC were consecutively enrolled between October 2012 and December 2014. Patients underwent both CESM and MRI before, during and after NAC. MRI was performed first, followed by CESM within 3 days. Response to therapy was evaluated for each patient, comparing the size of the residual lesion measured on CESM and MRI performed after NAC to the pathological response on surgical specimens (gold standard), independently of and blinded to the results of the other test. The agreement between measurements was evaluated using Lin's coefficient. The agreement between measurements using CESM and MRI was tested at each step of the study, before, during and after NAC. And last of all, the variation in the largest dimension of the tumor on CESM and MRI was assessed according to the parameters set in RECIST 1.1 criteria, focusing on pathological complete response (pCR). RESULTS: A total of 46 patients (85%) completed the study. CESM predicted pCR better than MRI (Lin's coefficient 0.81 and 0.59, respectively). Both methods tend to underestimate the real extent of residual tumor (mean 4.1mm in CESM, 7.5mm in MRI). The agreement between measurements using CESM and MRI was 0.96, 0.94 and 0.76 before, during and after NAC respectively. The distinction between responders and non-responders with CESM and MRI was identical for 45/46 patients. In the assessment of CR, sensitivity and specificity were 100% and 84%, respectively, for CESM, and 87% and 60% for MRI. CONCLUSION: CESM and MRI lesion size measurements were highly correlated. CESM seems at least as reliable as MRI in assessing the response to NAC, and may be an alternative if MRI is contraindicated or its availability is limited.

Sunitinib, pazopanib or sorafenib for the treatment of patients with late relapsing metastatic renal cell carcinoma.

PURPOSE: Late recurrence of renal cell carcinoma is not a rare event. In this retrospective study we investigate the clinicopathological features and the outcome of patients treated with sorafenib, sunitinib and pazopanib for late relapsing renal cell carcinoma. MATERIALS AND METHODS: Data were collected from 21 Italian centers involved in the treatment of metastatic renal cell carcinoma. Late relapse was defined as more than 5 years after initial radical nephrectomy. RESULTS: A total of 2,490 patients were screened and 269 (11%) were included in the study. First line therapy was sunitinib in 190 patients (71%), sorafenib in 58 (21%) and pazopanib in 21 (8%). Median progression-free survival was 20.0 months for sunitinib (95% CI 17.0-25.1), and 14.1 months for sorafenib (95% CI 11.0-29.0) and pazopanib (95% CI 11.2-not reported). On multivariate analysis MSKCC score and metastases to lymph nodes, liver and brain were associated with worst overall survival, while pancreatic metastases were associated with longer survival. Furthermore, age, MSKCC score and brain metastases were associated with worst progression-free survival. CONCLUSIONS: Patients with late relapsing renal cell carcinoma seem to present a characteristic pattern of metastatic spread without showing significant differences in terms of progression-free survival among sorafenib, sunitinib and pazopanib.

Safety and efficacy of sunitinib in patients from Italy with metastatic renal cell carcinoma: final results from an expanded-access trial.

OBJECTIVES: Patients with metastatic renal cell carcinoma (mRCC) received sunitinib in a global expanded-access program (EAP). Here, we report the efficacy and safety results for the EAP subpopulation in Italy. METHODS: Patients ≥18 years old with previously treated or treatment-naïve mRCC received oral sunitinib 50 mg/day on a 4-weeks-on/2-weeks-off schedule. Tumor measurements were scheduled per local practice (using Response Evaluation Criteria in Solid Tumors). Safety was regularly assessed. RESULTS: A total of 521 patients participated, including 40% aged ≥65 years, 11% with an Eastern Cooperative Oncology Group performance status ≥2, 14% with non-clear cell RCC, and 11% with brain metastases. The median treatment duration and posttreatment follow-up were 7.4 and 12.3 months, respectively. The objective response rate was 12%, and the median progression-free and overall survival was 9.1 and 27.2 months, respectively. 514 patients (99%) discontinued treatment; reasons included death (17%), nonresponse (46%), or adverse events (AEs; 13%). The most common any-grade treatment-related AEs were asthenia (44%, plus 15% reporting fatigue), thrombocytopenia and stomatitis (both 37%), diarrhea (36%), mucosal inflammation (29%), hypertension (26%), and dysgeusia (25%). The most common grade 3/4 treatment-related AEs were thrombocytopenia (10%), asthenia (9%, plus 3% reporting fatigue), neutropenia, stomatitis (both 6%), and hypertension (5%). CONCLUSION: In a large population of Italian mRCC patients, sunitinib had a manageable safety profile and encouraging efficacy.

Retrospective analysis on safety and efficacy of everolimus in treatment of metastatic renal cancer patients receiving dialysis.

AIMS: This retrospective study aimed to investigate safety and efficacy of everolimus in patients with metastatic renal cell carcinoma (mRCC) and end-stage renal disease requiring dialysis. PATIENTS & METHODS: From November 2009 to December 2012, 11 mRCC patients undergoing dialysis were treated with everolimus after failure of anti-VEGF therapy at six Italian institutions. Patient characteristics, safety and outcomes were collected. RESULTS: Progression-free survival and overall survival were determined using the Kaplan-Meier method. Median progression-free survival and overall survival were 9.01 and 15.7 months, respectively. No unexpected adverse events were reported. CONCLUSION: Everolimus appears to be safe in mRCC patients with renal impairment or end-stage renal disease requiring dialysis. Larger prospective studies are required to confirm these findings.

Assessing the effectiveness and safety of lenvatinib and everolimus in advanced renal cell carcinoma: insights from the RELIEVE study's analysis of heavily pretreated patients.

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.

Avelumab Plus Intermittent Axitinib in Previously Untreated Patients with Metastatic Renal Cell Carcinoma. The Tide-A Phase 2 Study.

BACKGROUND: Combinations of vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs) plus immune checkpoint inhibitor (ICI) against PD1/PD-L1 are the standard first-line therapy for patients with metastatic renal cell carcinoma (mRCC), irrespective of the prognostic class. OBJECTIVE: To investigate the feasibility and safety of withdrawing VEGFR-TKI but continuing anti-PD1/PD-L1 in patients who achieve a response to their combination. DESIGN, SETTING, AND PARTICIPANTS: This was a single-arm phase 2 trial in patients with treatment-naïve mRCC with prior nephrectomy, without symptomatic/bulky disease and no liver metastases. INTERVENTION: Enrolled patients received axitinib + avelumab; after 36 wk of therapy those who achieved a tumour response interrupted axitinib and continued avelumab maintenance until disease progression. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was the rate of patients without progression 8 wk after the axitinib interruption. The secondary endpoints were the median value for progression-free (mPFS) and overall (mOS) survival and the safety in the overall population. RESULTS AND LIMITATIONS: Seventy-nine patients were enrolled and 75 were evaluated for efficacy. A total of 29 (38%) patients had axitinib withdrawn, as per the study design, with 72% of them having no progression after 8 wk and thus achieving the primary endpoint. The mPFS of the overall population was 24 mo, while the mOS was not reached. The objective response rate was 76% (12% complete response and 64% partial response), with 19% of patients having stable disease. In the patients who discontinued axitinib, the incidence of adverse events of any grade was 59% for grade 3 and 3% for grade 4. This study was limited by the lack of a comparative arm. CONCLUSIONS: The TIDE-A study demonstrates that the withdrawal of VEGFR-TKI with ICI maintenance is feasible for selected mRCC patients with evidence of a response to the VEGFR-TKI + ICI combination employed in first-line therapy. Axitinib interruption with avelumab maintenance leads to decreased side effects and should be investigated further as a new strategy to delay tumour progression. PATIENT SUMMARY: We evaluated whether certain patients with advanced kidney cancer treated with the fist-line combination of axitinib plus avelumab can interrupt the axitinib in case of a tumour response after 36 wk of therapy. We found that axitinib interruption improved the safety of the combination, while the maintenance with avelumab might delay tumour progression.

Final Results from SAUL, a Single-arm International Study of Atezolizumab in Unselected Patients with Pretreated Locally Advanced/Metastatic Urinary Tract Carcinoma.

BACKGROUND AND OBJECTIVE: We assessed the safety of atezolizumab in unselected patients (including understudied populations typically excluded from clinical trials) with pretreated urinary tract carcinoma (UTC). The prespecified final analysis updates previously reported safety and efficacy data. METHODS: The single-arm prospective SAUL study (NCT02928406) enrolled 1004 patients with locally advanced/metastatic urothelial/non-urothelial UTC that had progressed during/after one to three prior treatment lines for advanced UTC (or <12 mo after [neo]adjuvant therapy). Broad eligibility criteria allowed enrollment of patients with complex comorbidities approximating the real-world setting. Patients received atezolizumab 1200 mg every 3 wk until disease progression or unacceptable toxicity. The primary endpoint was safety. Secondary endpoints included duration of response and overall survival (OS). KEY FINDINGS AND LIMITATIONS: The treated cohort included 10% of patients with poor performance status, 5% with creatinine clearance <30 ml/min, and 4% with autoimmune disease. At median follow-up of 55 mo, median atezolizumab duration was 2.8 mo (range 0-62); 68 patients (7%) continued atezolizumab for >4 yr. Treatment-related grade ≥3 adverse events occurred in 16% of patients (death in 1%); 8% discontinued atezolizumab for adverse events. Median OS was 8.6 mo (95% confidence interval 7.8-9.7) and 136 patients (14%) had OS longer than 4 yr. Limitations include the small sample size for some subgroups of special interest. CONCLUSIONS AND CLINICAL IMPLICATIONS: Long-term safety and efficacy data continue to show a benefit of atezolizumab in unselected patients with UTC. Remarkably, 14% of patients lived for >4 yr after starting atezolizumab. These results can inform multidisciplinary team discussions and treatment decision-making for patients with UTC with complex comorbidities. PATIENT SUMMARY: The SAUL study looked at how well tolerated a drug called atezolizumab was in patients with urinary tract cancer who had already received up to three previous treatments for their cancer, including people who are usually not included in clinical trials because of other medical conditions. The length of survival after starting treatment was also assessed. Overall, the results show that atezolizumab was well tolerated. People for whom other therapies had failed lived for about 8.6 months on average after starting treatment, and 14% of the patients were still alive after 4 years.

Time to strategy failure and treatment beyond progression in pretreated metastatic renal cell carcinoma patients receiving nivolumab: post-hoc analysis of the Meet-URO 15 study.

Background: Immunotherapies exhibit peculiar cancer response patterns in contrast to chemotherapy and targeted therapy. Some patients experience disease response after initial progression or durable responses after treatment interruption. In clinical practice, immune checkpoint inhibitors may be continued after radiological progression if clinical benefit is observed. As a result, estimating progression-free survival (PFS) based on the first disease progression may not accurately reflect the actual benefit of immunotherapy. Methods: The Meet-URO 15 study was a multicenter retrospective analysis of 571 pretreated metastatic renal cell carcinoma (mRCC) patients receiving nivolumab. Time to strategy failure (TSF) was defined as the interval from the start of immunotherapy to definitive disease progression or death. This post-hoc analysis compared TSF to PFS and assess the response and survival outcomes between patients treatated beyond progression (TBP) and non-TBP. Moreover, we evaluated the prognostic accuracy of the Meet-URO score versus the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) score based on TSF and PFS. Results: Overall, 571 mRCC patients were included in the analysis. Median TSF was 8.6 months (95% CI: 7.0 - 10.1), while mPFS was 7.0 months (95% CI: 5.7 - 8.5). TBP patients (N = 93) had significantly longer TSF (16.3 vs 5.5 months; p < 0.001) and overall survival (OS) (34.8 vs 17.9 months; p < 0.001) but similar PFS compared to non-TBP patients. In TBP patients, a median delay of 9.6 months (range: 6.7-16.3) from the first to the definitive disease progression was observed, whereas non-TBP patients had overlapped median TSF and PFS (5.5 months). Moreover, TBP patients had a trend toward a higher overall response rate (33.3% vs 24.3%; p = 0.075) and disease control rate (61.3% vs 55.5%; p = 0.31). Finally, in the whole population the Meet-URO score outperformed the IMDC score in predicting both TSF (c-index: 0.63 vs 0.59) and PFS (0.62 vs 0.59). Conclusion: We found a 2-month difference between mTSF and mPFS in mRCC patients receiving nivolumab. However, TBP patients had better outcomes, including significantly longer TSF and OS than non-TBP patients. The Meet-URO score is a reliable predictor of TSF and PFS.

The Italian Rare Biliary tract Cancer initiative (IRaBiCa): A multicentric observational study of Gruppo Oncologico dell'Italia Meridionale (GOIM) in collaboration with Gruppo Italiano Colangiocarcinoma (GICO).

INTRODUCTION: About 90% of cholangiocarcinomas are adenocarcinomas with glandular or tubular structures lined by epithelial cells, with no bile production and with a variable degree of differentiation, arising in the background of desmoplastic stroma. The remaining 10% is represented by rarer histological variants of which there is little knowledge regarding the biological behavior, molecular characterization, and sensitivity to the various possible therapies, including molecular-based treatments. Such rare tumors are described only in case reports or small retrospective series because of their exclusion from clinical trials. This national initiative, here presented, aims to address the following knowledge gap: a) how much does histological diversity translate into clinical manifestation variety? b) are those chemotherapy regimens, recommended for conventional biliary tract cancers, potentially active in rare variants?Therefore, epidemiological, pathological, and clinical characterization of series of rare biliary histotypes/variants, for which therapeutic and follow-up data are available, will be collected. METHODS: An Italian task force on rare tumors of the biliary tract (IRaBiCa) has been created, whose initiative is a multicenter retrospective study involving 34 Italian cancer centers.Clinical data from approximately 100 patients will be collected and analyzed. Continuous variables will be presented as median ± standard deviation, while categorical variables will be expressed in terms of frequency. Kaplan-Maier analyses will be used to compare disease free, progression free and overall survival, according to the different histotypes. CONCLUSIONS: We expect to gather novel data on rare histotypes of biliary tract cancer that will be useful to support their molecular and immunological characterization.

Metastatic renal cell carcinoma: how to make the best sequencing decision after withdrawal for intolerance to a tyrosine kinase inhibitor.

With seven agents approved for metastatic renal cell carcinoma (RCC) within the past few years, there has undoubtedly been progress in treating this disease. The treatment safety of these new agents, however, now represents a crucial concern, which requires a search for the best possible balance between the minimization of the treatment burden and the need for maintaining appropriate drug dosages able to induce the best clinical benefit. In this review we have analyzed safety data of all approved targeted agents for metastatic RCC available as first- or second-line therapy to provide suggestions aimed at establishing the most appropriate second-line or later treatment on the basis of toxicities that have arisen in therapy. Based on the characteristics and comorbidities of the patients and on the toxicity profile of each treatment, it is possible to plan different therapeutic options. We, therefore, have compiled a list of points that are important to keep in mind when considering the use of the targeted drugs for the treatment of advanced RCC.

Incidence and Survival of Testicular Cancers in a Province in Northern Italy and Their Association with Second Tumors.

This study investigated the incidence, mortality, and 5-year survival rates of testicular cancers diagnosed in a northern Italian province, which were eventually associated with previous or subsequent extratesticular neoplasms. Cases from 1996 to 2020 were examined by age and histotype (seminoma vs. non-seminoma). The standardized incidence rate was calculated using the European population, and the annual percent change (APC) was reported. The five-year relative survival was estimated using the Pohar Perme method. The association with the second neoplasm was also evaluated. In our study, 385 patients with testicular cancer were included, most of whom were aged between 30 and 40 years. The non-seminoma and seminoma groups accounted for 44% and 18% of younger adults, respectively. The incidence rate increased during the study period (APC 1.6*); however, it increased in seminomas (APC 2.3*) but not in non-seminomas (APC -0.1). Conversely, the mortality rate remained constantly low either overall or in each of the two groups. The overall 5-year survival rate of testicular cancer patients was 95% (99% and 88% for seminomas and non-seminomas, respectively). Primary extratesticular tumors were documented in 37 cases, 18 after and 19 before the testicular cancer diagnosis. Our study confirms that the increased incidence and excellent survival rate are the prerogative of seminomas.

The Impact of COVID-19 on New Kidney Cancer Diagnosis: Stage and Treatment in Northern Italy.

This study aims to evaluate the impact of COVID-19 on new renal carcinoma (RC) diagnoses using data from the Reggio Emilia Cancer Registry in 2018-2020. A total of 293 RCs were registered, with roughly 100 cases yearly. The distribution by age shows a significant decrease in the 30-59 age group (33.7% in 2018, 24.8% in 2019, and 19.8% in 2020). The incidence of Stage I was 59.4%, 46.5%, and 58.2% in 2018, 2019, and 2020, respectively, whereas the Stage II rate had values of 6.9%, 7.9%, and 2.2% in the years 2018, 2019, and 2020, respectively. Slight non-significant variations were observed in Stages III and IV. Surgery was performed in 83.2% of cases in 2018, 78.2% in 2019, and 82.4% in 2020; the surgery distribution by stage showed no significant differences. Chemotherapy showed an increase in 2020, which was statistically significant only for Stage IV. The gender incidence trends over the last 25 years showed an increase in the male sex in the first period; then, a decline was documented, likely due to a decrease in cigarette consumption. In females, the trend was constant. The RC mortality trend significantly dropped in both genders over the entire study period.

Hormone therapies (HTs) with anti-androgenic properties are a cornerstone for the treatment of prostate cancer (PC) and have significantly improved the survival of patients, though exposing them to a higher risk of cardiovascular diseases (CVDs), which represent a major cause of morbidity and mortality. This occurs due to the high average age of patients undergoing HT for PC, an age group in which CVDs have a high prevalence and incidence, and due to the type and duration of HTs that are increasingly effective but at the same time more aggressive towards cardiovascular health. Recent evidence from the real world suggests, however, that the cardiometabolic risk is widely underestimated and undertreated with significant impact also on the oncological prognosis. In the light of the results of the PRONOUNCE study, in this review it is emphasized the need for a multidisciplinary management of patients with PC who are candidate for or treated with HT by implementing a personalized treatment program in accordance with the current European guidelines on CVD prevention.

A multicenter phase 2 single arm study of cabozantinib in patients with advanced or unresectable renal cell carcinoma pre-treated with one immune-checkpoint inhibitor: The BREAKPOINT trial (Meet-Uro trial 03).

BACKGROUND: First-line therapies based on immune-checkpoint inhibitors (ICIs) significantly improved survival of metastatic renal cell carcinoma (mRCC) patients. Cabozantinib was shown to target kinases involved in immune-escape and to prolong survival in patients pre-treated with tyrosine-kinase-inhibitors (TKIs). The impact of ICIs combinations in first line on subsequent therapies is still unclear. METHODS: This is an open label, multicenter, single arm, phase II study designed to assess activity, safety and efficacy of cabozantinib in mRCC patients progressed after an adjuvant or first line anti-Programmed Death (PD)-1/PD-Ligand (PD-L) 1-based therapy. Primary endpoint was progression free survival (PFS), secondary endpoints were overall survival (OS), objective response rate (ORR) and safety. RESULTS: 31 patients were included in the analysis. After a median (m) follow-up of 11.9 months, mPFS was 8.3 months (90%CI 3.9-17.4) and mOS was 13.8 months (95%CI 7.7-29.0). ORR was 37.9% with an additional 13 patients achieving disease stability. Grade 3-4 adverse events occurred in 47% of patients, including more frequently creatine phosphokinase (CPK) serum level elevation, neutropenia, hyponatremia, diarrhea, hand-food syndrome, oral mucositis and hypertension. CONCLUSIONS: The BREAKPOINT trial met its primary endpoint showing that cabozantinib as second line therapy after ICIs was active in mRCC. Safety profile was manageable.

Current practice of genomic profiling of patients with advanced solid tumours in Italy: the Italian Register of Actionable Mutations (RATIONAL) study.

BACKGROUND: The Italian Register of Actionable Mutations (RATIONAL) is a multicentric, observational study collecting next-generation sequencing (NGS)-based tumour profiling data of patients with advanced solid tumours. METHODS: The study enrols patients who had available an NGS-based tumour profiling (Pathway-A) or undergo comprehensive genomic profiling (CGP) with FoundationOne CDx assays within the trial (Pathway-B). The primary endpoint was the rate of actionable mutations identified. RESULTS: Sequencing data were available for 738 patients in Pathway-A (218) and -B (520). In Pathway-A, 154/218 (70.6%) tests were performed using NGS panels ≤52 genes, and genomic alterations (GAs) were found in 164/218 (75.2%) patients. In Pathway-B, CGP revealed GAs in 512/520 (98.5%) patients. Levels I/II/III actionable GAs according to the European Society of Medical Oncology Scale for Clinical Actionability of molecular Targets (ESCAT) were identified in 254/554 (45.8%) patients with non-small-cell lung cancer, cholangiocarcinoma, colorectal, gastric, pancreatic and breast cancer. The rate of patients with level I GAs was similar in Pathways A and B (69 versus 102). CGP in Pathway-B revealed a higher number of patients with level II/III GAs (99 versus 20) and potentially germline pathogenic/likely pathogenic variants (58 versus 15) as compared with standard testing in Pathway-A. In patients with cancer of unknown primary, CGP detected OncoKB levels 3B/4 GAs in 31/58 (53.4%) cases. Overall, 67/573 (11.7%) of patients received targeted therapy based on genomic testing. CONCLUSION: The Italian Register of Actionable Mutations represents the first overview of genomic profiling in Italian current clinical practice and highlights the utility of CGP for identifying therapeutic targets in selected cancer patients.
