Global real-world experiences with pembrolizumab in advanced urothelial carcinoma after platinum-based chemotherapy: the ARON-2 study.

BACKGROUND: Immune checkpoint inhibitors have changed previous treatment paradigm of advanced urothelial carcinoma (UC). The ARON-2 study (NCT05290038) aimed to assess the real-world effectiveness of pembrolizumab in patients recurred or progressed after platinum-based chemotherapy. PATIENTS AND METHODS: Medical records of patients with documented metastatic UC treated by pembrolizumab as second-line therapy were retrospectively collected from 88 institutions in 23 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS) and overall response rate (ORR). Cox proportional hazards models were adopted to explore the presence of prognostic factors. RESULTS: In total, 836 patients were included: 544 patients (65%) received pembrolizumab after progression to first-line platinum-based chemotherapy in the metastatic setting (cohort A) and 292 (35%) after recurring within < 12 months since the completion of adjuvant or neoadjuvant chemotherapy (cohort B). The median follow-up time was 15.3 months. The median OS and the ORR were 10.5 months and 31% in the overall study population, 9.1 months and 29% in cohort A and 14.6 months and 37% in cohort B. At multivariate analysis, ECOG-PS ≥ 2, bone metastases, liver metastases and pembrolizumab setting (cohort A vs B) proved to be significantly associated with worst OS and PFS. Stratified by the presence of 0, 1-2 or 3-4 prognostic factors, the median OS was 29.4, 12.5 and 4.1 months (p < 0.001), while the median PFS was 12.2, 6.4 and 2.8 months, respectively (p < 0.001). CONCLUSIONS: Our study confirms that pembrolizumab is effective in the advanced UC real-world context, showing outcome differences between patients recurred or progressed after platinum-based chemotherapy.

Implementation of Precision Oncology in Clinical Practice: Results of a National Survey for Health Care Professionals.

BACKGROUND: Two main aspects lead the implementation of precision oncology into clinical practice: the adoption of extended genome sequencing technologies and the institution of the Molecular Tumor Boards (MTBs). CIPOMO (Italian Association of Heads of Oncology Department) promoted a national survey across top health care professionals to gain an understanding of the current state of precision oncology in Italy. METHODS: Nineteen questions were sent via the SurveyMonkey platform to 169 heads of oncology departments. Their answers were collected in February 2022. RESULTS: Overall, 129 directors participated; 113 sets of answers were analyzed. Nineteen regions out of 21 participated as a representative sample of the Italian health care system. The use of next-generation sequencing (NGS) is unevenly distributed; informed consent and clinical reports are managed differently, as the integration of medical, biologic, and informatics domains in a patient-centered workflow is inconsistent. A heterogeneous MTB environment emerged. A total of 33.6% of the responding professionals did not have access to MTBs while 76% of those who have did not refer cases. CONCLUSIONS: NGS technologies and MTBs are not homogeneously implemented in Italy. This fact potentially jeopardizes equal access chances to innovative therapies for patients. This survey was carried out as part of an organizational research project, pursuing a bottom-up approach to identify the needs and possible solutions to optimize the process. These results could be a starting point for clinicians, scientific societies, and health care institutions to outline the best practices and offer shared recommendations for precision oncology implementation in current clinical practice.

Use of concomitant proton pump inhibitors, statins or metformin in patients treated with pembrolizumab for metastatic urothelial carcinoma: data from the ARON-2 retrospective study.

BACKGROUND: Concomitant medications may potentially affect the outcome of cancer patients. In this sub-analysis of the ARON-2 real-world study (NCT05290038), we aimed to assess the impact of concomitant use of proton pump inhibitors (PPI), statins, or metformin on outcome of patients with metastatic urothelial cancer (mUC) receiving second-line pembrolizumab. METHODS: We collected data from the hospital medical records of patients with mUC treated with pembrolizumab as second-line therapy at 87 institutions from 22 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall response rate. We carried out a survival analysis by a Cox regression model. RESULTS: A total of 802 patients were eligible for this retrospective study; the median follow-up time was 15.3 months. PPI users compared to non-users showed inferior PFS (4.5 vs. 7.2 months, p = 0.002) and OS (8.7 vs. 14.1 months, p < 0.001). Concomitant PPI use remained a significant predictor of PFS and OS after multivariate Cox analysis. The use of statins or metformin was not associated with response or survival. CONCLUSIONS: Our study results suggest a significant prognostic impact of concomitant PPI use in mUC patients receiving pembrolizumab in the real-world context. The mechanism of this interaction warrants further elucidation.

The prognostic nutritional index predicts survival and response to first-line chemotherapy in advanced biliary cancer.

BACKGROUND: An accurate risk-stratification is key to optimize the benefit-to-risk ratio of palliative treatment in advanced biliary cancer. We aimed at assessing the impact of the prognostic nutritional index (PNI) on survival and treatment response in advanced biliary cancer (ABC) receiving first-line chemotherapy. METHODS: Medical records of ABC treated with standard chemotherapy at the Modena Cancer Centre were retrospectively reviewed for variables deemed of potential interest, including the PNI. Univariate and multivariate analyses were performed to investigate the association between the covariates and overall survival (OS). RESULTS: 114 ABC fulfilled the inclusion criteria and made up the training cohort. A PNI cut-off value of 36.7 was established using the receiver operating characteristic (ROC) analysis. At both the univariate and the multivariate analysis, low PNI value (<36.7) was associated with shorter OS (P = .0011), together with increased NLR (P = .0046) and ECOG >1 (P < .0001). The median OS was 5.4 vs 12.1 months in the low- vs high PNI-group. Moreover, a PNI value >36.7 resulted in a higher disease control in patients treated with gemcitabine/platinum combination (61.4% vs 34.3%). These results were validated in an independent cohort of 253 ABC. CONCLUSIONS: We demonstrated and externally validated a prognostic role for the PNI in ABC treated with first-line chemotherapy. Although the PNI turned out to be predictive in the subset of patients receiving platinum/gemcitabine combination, future prospective confirmation is needed.

Cardiovascular safety of abiraterone acetate in metastatic castration-resistant prostate cancer patients: a prospective evaluation.

AIM: The aim of this study is to evaluate cardiotoxicity of abiraterone acetate (AA) in metastatic castration-resistant prostate cancer patients (pts) with cardiovascular comorbidities or coronary artery disease (CAD) risk factors. PATIENTS & METHODS: We prospectively analyzed pts receiving AA in order to evaluate correlations between cardiotoxicity onset and CAD risk factors or cardiovascular comorbidities. RESULTS: Eighty-seven pts were enrolled, with median treatment duration of 9 months (1-44). At baseline, 84 pts (96%) had CAD risk factors. During treatment four pts (4; 6%) developed hypertension and 26 pts (30%) worsened the preexisting hypertension. Median left ventricular ejection fraction were 64 and 63% at baseline and after treatment, respectively. CONCLUSION: AA appears to be safe in pts with cardiovascular comorbidities or CAD risk factors.

Outcome of Patients with Renal Cell Carcinoma and Multiple Glandular Metastases Treated with Targeted Agents.

PURPOSE: Pancreatic metastases (PM) from renal cell carcinoma (RCC) have been associated with long-term survival. The aim of this study was to evaluate the outcome of RCC patients with multiple glandular metastases (MGM) treated with targeted therapies (TTs). METHODS: Sixty-four MGM patients treated between 1993 and 2014 were retrospectively identified from a database of 274 RCC patients with PM from 11 European centers. The survival of MGM patients was compared with that of both patients with PM only and a cohort of 325 RCC patients with non-GM (control group) treated with TTs. Survival was estimated using the Kaplan-Meier method and was statistically compared using the log-rank test. RESULTS: Fifty-six patients (88%) had at least 2 MGM, 7 patients (11%) had 3 MGM and 1 patient had 4 MGM, while non-GM were present in the remaining patients. The median overall survival (OS) was 54.2 months for MGM and 73.4 months for patients with PM only. The median OS in the control group was 22.7 months and statistically inferior to both MGM (p < 0.001) and PM patients (p < 0.001). CONCLUSION: MGM from RCC are associated with a remarkable survival. Despite some limitations, these findings suggest that GM might be considered a predictor of a favorable prognosis.

Clinical outcomes in octogenarians treated with docetaxel as first-line chemotherapy for castration-resistant prostate cancer.

AIM: To assess clinical outcomes in octogenarians treated with docetaxel (DOC) for metastatic castration-resistant prostate cancer. PATIENTS & METHODS: The multicenter retrospective study was based on a review of the pre- and post-DOC clinical history, DOC treatment and outcomes. RESULTS: We reviewed the records of 123 patients (median age: 82 years) who received DOC every 3 weeks or weekly, without significant grade 3-4 toxicities. Median progression-free survival was 7 months; median overall survival from the start of DOC was 20 months, but post-progression treatments significantly prolonged overall survival. CONCLUSION: The findings of this study suggest that toxicity is acceptable, survival is independent of patient's age and survival can be significantly prolonged by the use of new agents.

Targeting bone metastatic cancer: Role of the mTOR pathway.

One of the great challenges of cancer medicine is to develop effective treatments for bone metastatic cancer. Most patients with advanced solid tumors will develop bone metastasis and will suffer from skeletal related events associated with this disease. Although some therapies are available to manage symptoms derived from bone metastases, an effective treatment has not been developed yet. The mammalian target of rapamycin (mTOR) pathway regulates cell growth and survival. Alterations in mTOR signaling have been associated with pathological malignancies, including bone metastatic cancer. Inhibition of mTOR signaling might therefore be a promising alternative for bone metastatic cancer management. This review summarizes the current knowledge on mTOR pathway signaling in bone tissue and provides an overview on the known effects of mTOR inhibition in bone cancer, both in in vitro and in vivo models.

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.

Prognostic factors in patients receiving third line targeted therapy for metastatic renal cell carcinoma.

PURPOSE: Several prognostic models have been proposed for metastatic renal cell carcinoma but none has been validated in patients who receive third line targeted agents. We evaluated prognostic factors in patients with metastatic renal cell carcinoma who received a third line targeted agent. MATERIALS AND METHODS: We retrospectively reviewed data on 2,065 patients with clear cell metastatic renal cell carcinoma who were treated with targeted therapy at a total of 23 centers in Italy. Included in final analysis were 281 patients treated with 3 targeted agents. Overall survival was the main outcome. Cox proportional hazards regression followed by bootstrap validation was used to identify independent prognostic factors. RESULTS: Three clinical characteristics (ECOG performance status greater than 1, metastasis at diagnosis and liver metastasis) and 2 biochemical factors (hemoglobin less than the lower limit of normal and neutrophil count greater than the upper limit of normal, respectively) were prognostic. Patients were classified into 3 risk categories, including low-zero or 1, intermediate-2 and high risk-more than 2 risk factors. Median overall survival was 19.7, 10.1 and 5.5 months, and 1-year overall survival was 71%, 43% and 15%, respectively. The major limitation was the retrospective nature of this study and absent external validation. CONCLUSIONS: This nomogram included clinical and biochemical prognostic factors. In clinical trials it may be useful to select patients and define the prognosis.

Surgical resection does not improve survival in patients with renal metastases to the pancreas in the era of tyrosine kinase inhibitors.

BACKGROUND: The aim of this study was to compare survival of resected and unresected patients in a large cohort of patients with metastases to the pancreas from renal cell carcinoma (PM-RCC). METHODS: Data from 16 Italian centers involved in the treatment of metastatic RCC were retrospectively collected. The Kaplan-Meier and log-rank test methods were used to evaluate overall survival (OS). Clinical variables considered were sex, age, concomitant metastasis to other sites, surgical resection of PM-RCC, and time to PM-RCC occurrence. RESULTS: Overall, 103 consecutive patients with radically resected primary tumors were enrolled in the analysis. PM-RCCs were synchronous in only three patients (3 %). In 56 patients (54 %), the pancreas was the only metastatic site, whereas in the other 47 patients, lung (57 %), lymph nodes (28 %), and liver (21 %) were the most common concomitant metastatic sites. Median time for PM-RCC occurrence was 9.6 years (range 0-24 years) after nephrectomy. Surgical resection of PM-RCC was performed in 44 patients (median OS 103 months), while 59 patients were treated with tyrosine kinase inhibitors (TKIs; median OS 86 months) (p = 0.201). At multivariate analysis, Memorial Sloan Kettering Cancer Center risk group was the only independent prognostic factor. None of the other clinical variables, such as age, sex, pancreatic surgery, or the presence of concomitant metastases, were significantly associated with outcome in PM-RCC patients. CONCLUSIONS: The presence of PM-RCC is associated with a long survival, and surgical resection does not improve survival in comparison with TKI therapy. However, surgical resection leads to a percentage of disease-free PM-RCC patients.

[What patients with cancer think about the dehospitalization. A survey of Cipomo.] / Cosa pensano i pazienti oncologici circa le cure di prossimità. Risultato della survey del Cipomo.

BACKGROUND: Ministerial Decrete 77 (DM 77) promotes dehospitalization for chronic patients and defines out-of-hospital health facilities at this purpose. It has never been investigated how much patients with cancer know and judge this decree law. MATERIAL AND METHODS: The Collegio italiano dei primari oncologi medici ospedalieri (Cipomo) carried out a survey with a dedicated questionnaire on oncological patients attending public hospital to investigate the liking of DM 77. RESULTS: Anonymous responses were obtained from 1.443 patients. Median age 64ys, 42% males, 21% live alone, 70% have a companion. 19% thinks that oral chemotherapy could be managed outside the hospital, 26.68% carried out follow-up (FU),19.15% parenteral therapy, 32.16% basic examinations. Home is preferred by 21.8%, a health facility close to home by 36.3%, hospital by 37.54%. 59.67% would like FU in hospital by their personal oncologist, 5.47% by GP, 35.41% by both together and 9.45% by oncologist outside the hospital. Asked what they might feel about being followed out of the hospital, 29.94% say of not being treated at its best, 12.68% of not being able to be visited in hospital anymore, 5.27% of being abandoned, 30.7% of being freer and 10.88% of feeling less sick. Regarding the use of new technical tools to favor dehospitalisation, 44.15% answered yes, 15.88% no and 30.07% did not know. About the distance or traveling time from home to the therapy administration side, 20.26% answered this should be no more than 15 km or 30 mins, 9.91% no more than 30 km or 45 mins, 5.47% no more than 50 km or 60 mins but 39.5% say that the distance does not matter to them but only the continuity of care. The question related to the inconveniences with going to hospital for therapy: 40.81% waiting time, 20.47% lack of parking, 17.02% rotation of doctors,12.76% travel time and 5.62% bureaucracy. CONCLUSIONS: The patients' answers suggest that dehospitalization could improve their quality of life, but at the condition of being able to maintain a close relationship with the personal oncologist.

TEAM Study: Upfront Docetaxel Treatment in Patients With Metastatic Hormone-Sensitive Prostate Cancer: A Real-World, Multicenter, Retrospective Analysis.

BACKGROUND: Treatment of metastatic hormone-sensitive prostate cancer (mHSPC) dramatically changed. PEACE-1 and ARASENS trials established triplet therapy efficacy. Identifying prognostic factors supporting treatment choice is pivotal. METHODS: TEAM is an observational, retrospective study to evaluate prognostic role of variables in mHSPC patients receiving upfront docetaxel in 11 Italian centers. Outcome measures were progression-free survival (PFS) and overall-survival (OS). RESULTS: From September 2014 to December 2020, 147 patients were included. Median PFS and OS were 11.6 and 37.4 months. At univariate analysis, PFS-related variables were Gleason Score (GS) (P = .001), opioid use (P = .004), bone metastases number (P < .001), baseline PSA (P = .006), Hb (P < .001), ALP (P < .001) and LDH (P = .002), time between ADT and docetaxel start (P = .018), 3-month PSA (P < .001) and ALP (P < .001), and number of docetaxel cycles (P < .001). OS-related variables were PSA at diagnosis (P = .024), primary tumor treatment (P = .022), baseline pain (P = .015), opioid use (P < .001), bone metastases number (P < . 001), baseline Hb (P < .001), ALP (P < .001) and LDH (P = .001), NLR ratio (P = .039), 3-month PSA (P < .001) and ALP (P < .001) and docetaxel cycles number (P < .001). At multivariate analysis, independent prognostic variables were GS, opioid use, baseline LDH and time between ADT and docetaxel initiation for PFS, and baseline Hb and LDH for OS. CONCLUSION: Patients receiving upfront docetaxel with high GS, high disease burden, pain or opioid use, baseline unfavorable laboratory values had worse outcomes. Patients had greater docetaxel benefit when initiated early after ADT start. These parameters could be taken into account when selecting candidates for triplet therapy.

Real-world Outcome of Patients with Advanced Renal Cell Carcinoma and Intermediate- or Poor-risk International Metastatic Renal Cell Carcinoma Database Consortium Criteria Treated by Immune-oncology Combinations: Differential Effectiveness by Risk Group?

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.

Pazopanib in advanced and platinum-resistant urothelial cancer: an open-label, single group, phase 2 trial.

BACKGROUND: The development of new drugs for patients with refractory urothelial cancer is still an unmet medical need. Preclinical evidence lends support to a rationale for targeting of the VEGF or platelet-derived growth-factor axis. We therefore investigated the activity and safety of pazopanib, a multitarget drug with antiangiogenic activity, in patients with urothelial cancer. METHODS: In an open-label, single-group, phase 2 study, patients (aged ≥18 years) with relapsed or refractory urothelial cancer were given pazopanib 800 mg per day, orally. They were treated until disease progression or prohibitive toxicity occurred. The primary endpoint was the proportion of patients who achieved a confirmed objective response, defined as complete or partial response, after independent review, and was analysed by intention to treat. The trial is registered with ClinicalTrials.gov, number NCT01031875. FINDINGS: The trial has been completed. 21 (51%) of 41 patients enrolled were given pazopanib as third-line or further-line treatment. 26 (63%) patients had an Eastern Cooperative Oncology Group performance status of 1 or 2. Seven patients had a confirmed objective response (17·1%, 95% CI 7·2-32·1), all of which were partial responses. The most frequent treatment-related grade 3 adverse events were hypertension (three [7%]), fatigue (two [5%]), and gastrointestinal and vaginal fistulisations (two each [5%]). One patient died as a result of duodenal fistulisation that was related to tissue response of bulky tumour masses. INTERPRETATION: Pazopanib has single-agent activity in patients with heavily pretreated metastatic urothelial cancer, and warrants further study in this setting. Particular attention should be paid to patients with bulky tumour masses adjacent to viscera because fistulisation is probably related to the response to pazopanib and is the most frequent serious adverse event. FUNDING: Fondazione IRCCS Istituto Nazionale dei Tumori provided the grant. GlaxoSmithKline provided the study drug and provided funding for the independent radiological review.

Geographical differences in the management of metastatic de novo renal cell carcinoma in the era of immune-combinations.

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.

Safety of extended interval dosing immune checkpoint inhibitors: a multicenter cohort study.

BACKGROUND: Real-life spectrum and survival implications of immune-related adverse events (irAEs) in patients treated with extended interval dosing (ED) immune checkpoint inhibitors (ICIs) are unknown. METHODS: Characteristics of 812 consecutive solid cancer patients who received at least 1 cycle of ED monotherapy (pembrolizumab 400 mg Q6W or nivolumab 480 mg Q4W) after switching from canonical interval dosing (CD; pembrolizumab 200 mg Q3W or nivolumab 240 mg Q2W) or treated upfront with ED were retrieved. The primary objective was to compare irAEs patterns within the same population (before and after switch to ED). irAEs spectrum in patients treated upfront with ED and association between irAEs and overall survival were also described. RESULTS: A total of 550 (68%) patients started ICIs with CD and switched to ED. During CD, 225 (41%) patients developed any grade and 17 (3%) G3 or G4 irAEs; after switching to ED, any grade and G3 or G4 irAEs were experienced by 155 (36%) and 20 (5%) patients. Switching to ED was associated with a lower probability of any grade irAEs (adjusted odds ratio [aOR] = 0.83, 95% confidence interval [CI] = 0.64 to 0.99; P = .047), whereas no difference for G3 or G4 events was noted (aOR = 1.55, 95% CI = 0.81 to 2.94; P = .18). Among patients who started upfront with ED (n = 232, 32%), 107 (41%) developed any grade and 14 (5%) G3 or G4 irAEs during ED. Patients with irAEs during ED had improved overall survival (adjusted hazard ratio [aHR] = 0.53, 95% CI = 0.34 to 0.82; P = .004 after switching; aHR = 0.57, 95% CI = 0.35 to 0.93; P = .025 upfront). CONCLUSIONS: Switching ICI treatment from CD and ED did not increase the incidence of irAEs and represents a safe option also outside clinical trials.

Use of tyrosine kinase inhibitors in patients with metastatic kidney cancer receiving haemodialysis: a retrospective Italian survey.

UNLABELLED: What's known on the subject? and What does the study add? Sunitinib and sorafenib are orally administered multikinase inhibitors approved for the treatment of advanced RCC. The limited pharmacokinetics data on sunitinib and sorafenib suggest that haemodialysis does not significantly alter plasma concentrations. In this retrospective study we define the safety and efficacy of tyrosine kinase inhibitors in patients with metastatic RCC (mRCC) and end-stage renal disease requiring haemodialysis. Even though the retrospective nature of this survey and the relatively small sample size represent major limitations, these data indicate that treatment with sunitinib and sorafenib in this cohort of patients is feasible with no unexpected toxicity and good efficacy, results similar to those in the general population of patients with mRCC. OBJECTIVE: To investigate the safety and efficacy of tyrosine kinase inhibitors (TKIs) in patients with metastatic renal cell carcinoma (mRCC) and end-stage renal disease requiring haemodialysis (HD). PATIENTS AND METHODS: Between July 2006 and December 2010, 24 patients undergoing HD were treated with sunitinib and/or sorafenib for mRCC in 14 Italian institutions. We retrospectively reviewed the medical records of these patients to evaluate the administered doses of TKIs, treatment-related toxicities and the clinical response to therapy. RESULTS: Sunitinib was administered at 50 mg daily for 4-6 weeks in six patients, 37.5 mg daily for 4-6 weeks in seven patients (one patient subsequently increased the dose to 50 mg daily), 25 mg daily for 4-6 weeks in two patients and 12.5 mg daily for 4-6 weeks in one patient. Among the eight patients treated with sorafenib, four patients received 800 mg daily (400 mg every 12 h), three patients 400 mg daily and one patient 200 mg daily with a continuous schedule. The estimated median progression-free and overall survival periods of this cohort of patients were 10.3 months and 22.6 months, respectively. With regard to tolerability and safety, no unexpected adverse events were registered and no grade 4 haematological or non-haematological toxicities were reported. CONCLUSIONS: Sunitinib and sorafenib treatment is not contraindicated in patients with mRCC undergoing HD. The outcome of this patient population is similar to that observed in patients with normal renal function treated with TKIs. These results merit further confirmation by a larger prospective trial.

Central nervous system metastases from castration-resistant prostate cancer in the docetaxel era.

Central nervous system (brain or leptomeningeal) metastases (BLm) are considered rare in castration-resistant prostate cancer (CRPC) patients. Now that docetaxel has become the reference drug for first-line treatment of CRPC, patients whose disease is not controlled by hormonal manipulations may live much longer than before and have higher risk of developing BLm. We retrospectively reviewed the records of all patients with CRPC attending our centres from 2002 to 2010, and identified all of those who were diagnosed as having BLm and received (or were considered to have been eligible to receive) docetaxel-based treatment. We identified 31 cases of BLm (22 brain metastases and 9 leptomeningeal metastases) with an incidence of 3.3%. BLm-free survival was 43.5 months, and survival after BLm discovery was 4 months. With six patients surviving for more than 1 year after developing BLm, the projected 1-year BL-S rate was 25.8%. The findings of our study may be relevant in clinical practice as they indicate that incidence of BLm in CRPC patients in the docetaxel era seems to be higher than in historical reports, meaning that special attention should be paid to the appearance of neurological symptoms in long-term CRPC survivors because they may be related to BLm.

New emerging targets in advanced urothelial carcinoma: Is it the primetime for personalized medicine?

In recent years the introduction of immunotherapy has importantly changed the treatment landscape of advanced urothelial carcinoma. Several immune checkpoint inhibitors are now the standard of care as maintenance treatment after disease control with platinum-based first-line chemotherapy (avelumab), in subsequent lines (pembrolizumab) or as upfront therapy in platinum-ineligible patients (atezolizumab or pembrolizumab). Moreover, personalized therapy based on tumor molecular features has been developed. Namely, the increasing knowledge of the pathogenesis and molecular pathways underlying cancer development and progression is leading the introduction of target therapies such as the recently approved fibroblastic growth factor receptor (FGFR) inhibitor erdafitinib or the anti-nectin 4 antibody drug-conjugated enfortumab vedotin. Consequently, clinicians face new challenges, such as the choice of the best therapeutic sequence for each patient. The aim of this review is focusing on the emerging treatment options in metastatic urothelial carcinoma and discussing clinical features for choosing therapeutic sequencing.
