Endocrine-metabolic assessment checklist for cancer patients treated with immunotherapy: A proposal by the Italian Association of Medical Oncology (AIOM), Italian Association of Medical Diabetologists (AMD), Italian Society of Diabetology (SID), Italian Society of Endocrinology (SIE) and Italian Society of Pharmacology (SIF) multidisciplinary group.

Immunotherapy with immune checkpoint inhibitors (ICI) is increasingly employed in oncology. National and international endocrine and oncologic scientific societies have provided guidelines for the management of endocrine immune-related adverse events. However, guidelines recommendations differ according to the specific filed, particularly pertaining to recommendations for the timing of endocrine testing. In this position paper, a panel of experts of the Italian Association of Medical Oncology (AIOM), Italian Association of Medical Diabetologists (AMD), Italian Society of Diabetology (SID), Italian Society of Endocrinology (SIE), and Italian Society of Pharmacology (SIF) offers a critical multidisciplinary consensus for a clear, simple, useful, and easily applicable endocrine-metabolic assessment checklist for cancer patients on immunotherapy.

Anti-EGFR Rechallenge in Patients With Refractory ctDNA RAS/BRAF wt Metastatic Colorectal Cancer: A Nonrandomized Controlled Trial.

Importance: The available evidence regarding anti-epidermal growth factor receptor (EGFR) inhibitor rechallenge in patients with refractory circulating tumor DNA (ctDNA) RAS/BRAF wild-type (wt) metastatic colorectal cancer (mCRC) is derived from small retrospective and prospective studies. Objective: To evaluate the efficacy of anti-EGFR rechallenge in patients with refractory ctDNA RAS/BRAF wt mCRC. Design, Setting, and Participants: This nonrandomized controlled trial used a pooled analysis of individual patient data from patients with RAS/BRAF wt ctDNA mCRC enrolled in 4 Italian trials (CAVE, VELO, CRICKET, and CHRONOS) and treated with anti-EGFR rechallenge between 2015 and 2022 (median [IQR] follow-up, 28.1 [25.8-35.0] months). Intervention: Patients received anti-EGFR rechallenge therapy, including cetuximab plus avelumab, trifluridine-tipiracil plus panitumumab, irinotecan plus cetuximab, or panitumumab monotherapy. Main Outcomes and Measures: Overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and disease control rate (DCR) were calculated. Exploratory subgroup analysis evaluating several clinical variables was performed. Safety was reported. Results: Overall, 114 patients with RAS/BRAF wt ctDNA mCRC (median [IQR] age, 61 [29-88] years; 66 men [57.9%]) who received anti-EGFR rechallenge as experimental therapy (48 received cetuximab plus avelumab, 26 received trifluridine-tipiracil plus panitumumab, 13 received irinotecan plus cetuximab, and 27 received panitumumab monotherapy) were included in the current analysis. Eighty-three patients (72.8%) had received 2 previous lines of therapy, and 31 patients (27.2%) had received 3 or more previous lines of therapy. The ORR was 17.5% (20 patients), and the DCR was 72.3% (82 patients). The median PFS was 4.0 months (95% CI, 3.2-4.7 months), and the median OS was 13.1 months (95% CI, 9.5-16.7 months). The subgroup of patients without liver involvement had better clinical outcomes. The median PFS was 5.7 months (95% CI, 4.8-6.7 months) in patients without liver metastasis compared with 3.6 months (95% CI, 3.3-3.9 months) in patients with liver metastasis (hazard ratio, 0.56; 95% CI, 0.37-0.83; P = .004). The median OS was 17.7 months (95% CI, 13-22.4 months) in patients without liver metastasis compared with 11.5 months (95% CI, 9.3-13.9 months) in patients with liver metastasis (hazard ratio, 0.63; 95% CI, 0.41-0.97; P = .04). Treatments showed manageable toxic effects. Conclusions and Relevance: These findings suggest that anti-EGFR rechallenge therapy has promising antitumor activity in patients with refractory ctDNA RAS/BRAF wt mCRC. Within the limitation of a subgroup analysis, the absence of liver metastases was associated with significant improved survival.

Treatment of bone metastases from solid tumors with bone-modifying agents: a web survey of Italian oncologists investigating patterns of practice drug prescription and prevention of side effects.

PURPOSE: Optimal use of bone-modifying agents (BMAs) in patients with bone metastases from solid tumors is uncertain in some aspects: the drug choice; the planned treatment duration and long-term therapy; the prevention and management of possible side effects, including renal toxicity, hypocalcaemia, and medication-related osteonecrosis of the jaw (MRONJ). METHODS: Italian oncologists were invited to fulfil a 24-question web survey about prescription of BMAs for bone metastases of breast cancer, prostate cancer, and other solid tumors. Prevention and management of side effects were also investigated. RESULTS: Answers of 191 oncologists were collected. BMAs are usually prescribed at the time of diagnosis of bone metastases by 87.0% (breast cancer) and 76.1% (solid tumors except breast and prostate cancers) of oncologists; the decision is more articulated for prostate cancer (endocrine-sensitive versus castration-resistant). The creatinine level (32.3%), the availability of patient venous access (15.8%), and the type of primary neoplasm (13.6%) are the most reported factors involved in choice between bisphosphonates and denosumab. Zoledronic acid every 3 months was considered as a valid alternative to monthly administration by 94% of Italian oncologists. Oncologists reported a good confidence with measures aimed to prevent MRONJ, whereas uncertainness about prevention and management of hypocalcemia was registered. CONCLUSION: Italian oncologists showed a high attitude in prescribing bisphosphonates or denosumab at the time of diagnosis of bone metastases, with a large application of preventive measures of side effects. Further studies are needed to investigate some controversial aspects, such as optimal drug treatment duration and long-term drug schedules.

Challenges and controversies in resectable non-small cell lung cancer: a clinician's perspective.

The treatment landscape of resectable early-stage non-small cell lung cancer (NSCLC) is transforming due to the approval of novel adjuvant and neoadjuvant systemic treatments. The European Medicines Agency (EMA) recently approved adjuvant osimertinib, adjuvant atezolizumab, adjuvant pembrolizumab, and neoadjuvant nivolumab combined with chemotherapy, and the approval of other agents or new indications may follow soon. Despite encouraging results, many unaddressed questions remain. Moreover, the transformed treatment paradigm in resectable NSCLC can pose major challenges to healthcare systems and magnify existing disparities in care as differences in reimbursement may vary across different European countries. This Viewpoint discusses the challenges and controversies in resectable early-stage NSCLC and how existing inequalities in access to these treatments could be addressed.

New systemic treatment paradigms in resectable non-small cell lung cancer and variations in patient access across Europe.

The treatment landscape of resectable early-stage non-small cell lung cancer (NSCLC) is set to change significantly due to encouraging results from randomized trials evaluating neoadjuvant and adjuvant immunotherapy, as well as adjuvant targeted therapy. As of January 2024, marketing authorization has been granted for four new indications in Europe, and regulatory approvals for other study regimens are expected. Because cost-effectiveness and reimbursement criteria for novel treatments often differ between European countries, access to emerging developments may lead to inequalities due to variations in recommended and available lung cancer care throughout Europe. This Series paper (i) highlights the clinical studies reshaping the treatment landscape in resectable early-stage NSCLC, (ii) compares and contrasts approaches taken by the European Medicines Agency (EMA) for drug approval to that taken by the United States Food and Drug Administration (FDA), and (iii) evaluates the differences in access to emerging treatments from an availability perspective across European countries.

Self-Completion Questionnaire on Sleep Evaluation in Patients Undergoing Oxaliplatin Therapy: An Observational Study.

Sleep is a fundamental human need; sleep disruption, in fact, causes an increase in the activity of the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis, metabolic effects, changes in circadian rhythms, and pro-inflammatory responses. The scientific literature is finally starting to pay attention to the central role of sleep alterations in patients health. Oxaliplatin is extensively used for the treatment of gastrointestinal cancer and other malignancies, with an increased frequency of use in recent years. This study aims to understand the effects of sleep complaints on health and quality of life in cancer patients treated with oxaliplatin. A study has been conducted through the creation and distribution of questionnaires to patients to investigate their complaints about sleep quality. We observed significant differences between males and females in evaluating sleep hygiene scores, the Pittsburgh Sleep Quality Index, and previous difficulty sleeping. Moreover, in females, stress, worries, and anxiety seem to play a negative role in the sleep hygiene score. The obtained results could improve the interest of healthcare personnel and caregivers in sleep quality in patients undergoing chemotherapy.

Gut and local microbiota in patients with cancer: increasing evidence and potential clinical applications.

In recent years, cancer research has highlighted the role of disrupted microbiota in carcinogenesis and cancer recurrence. However, microbiota may also interfere with drug metabolism, influencing the efficacy of cancer drugs, especially immunotherapy, and modulating the onset of adverse events. Intestinal micro-organisms can be altered by external factors, such as use of antibiotics, proton pump inhibitors treatment, lifestyle and the use of prebiotics or probiotics. The aim of our review is to provide a picture of the current evidence about preclinical and clinical data of the role of gut and local microbiota in malignancies and its potential clinical role in cancer treatments. Standardization of microbiota sequencing approaches and its modulating strategies within prospective clinical trials could be intriguing for two aims: first, to provide novel potential biomarkers both for early cancer detection and for therapeutic effectiveness; second, to propose personalized and "microbiota-tailored" treatment strategies.

Management of cancer treatment-induced bone loss in patients with breast and hormone sensitive prostate cancer: AIOM survey.

PURPOSE: Cancer treatment-induced bone loss is a side effect of hormonal therapy that can severely affect patients' quality of life. The aim of this survey was to obtain an updated picture of management of bone health in patients with breast cancer undergoing adjuvant hormonal therapy and in patients with hormone sensitive prostate cancer according to Italian oncologists. METHODS: Our survey was made up of 21 multiple-choice questions: the first part dealt with the respondents' characteristics, while the second with management of bone health in the described setting. An invitation to complete the survey was sent by e-mail to 2336 oncologists, members of Italian Association of Medical Oncology, in October 2022. RESULTS: Overall, 121 (5.2%) Italian oncologists completed the survey. In most cases (57%) the oncologist personally took charge of the management of bone health in patients at risk for cancer treatment-induced bone loss. At the beginning of hormonal therapy, most respondents reported to require bone health diagnostic exams, such as dual-energy X-ray absorptiometry (89%), repeated with different timing. Main reported reasons (not mutually exclusive) for prescribing antiresorptive drugs were modifying fracture risk (87%), densitometry values (75%) or prognosis (34%). Answers about the management of antiresorptive therapy were heterogeneous. CONCLUSION: A heterogeneous approach on the management of cancer treatment-induced bone loss in Italy arises from this survey. This scenario highlights the need for a major consensus of the Italian scientific community on the diagnostic and therapeutic approach of cancer treatment-induced bone loss and for a greater awareness of this topic among Italian oncologists.

Significance of PD-L1 in Metastatic Urothelial Carcinoma Treated With Immune Checkpoint Inhibitors: A Systematic Review and Meta-Analysis.

Importance: Immune checkpoint inhibitors (ICIs) have broadened the metastatic urothelial carcinoma (mUC) therapeutic scenario. The association of programmed death ligand 1 (PD-L1) with response and survival in patients treated with ICIs is still controversial. Objectives: To evaluate the association of PD-L1 with response rate and overall survival among patients with mUC treated with ICIs. Data Sources: PubMed, Embase, American Society of Clinical Oncology and European Society for Medical Oncology Meeting Libraries, and Web of Science were searched up to December 10, 2023. Study Selection: Two authors independently screened the studies. Included studies were randomized and nonrandomized clinical trials enrolling patients with mUC receiving ICIs with available overall survival (OS), progression-free survival (PFS), or overall response rate (ORR) data, separated between patients with PD-L1-positive and -negative tumors. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed. Two reviewers independently extracted data. Fixed- or random-effects models were used depending on the heterogeneity among the studies. Main Outcomes and Measures: Primary outcomes were odds ratios (ORs) for ORR and hazard ratios (HRs) for OS, comparing patients with PD-L1-positive tumors and patients with PD-L1-negative tumors. Secondary outcomes were the PFS HR between patients with PD-L1-positive and -negative tumors and OS HR between ICI arms and non-ICI arms of only randomized clinical trials. Results: A total of 14 studies were selected, comprising 5271 patients treated with ICIs (2625 patients had PD-L1-positive tumors). The ORR was 13.8% to 78.6% in patients with PD-L1-positive tumors and 5.1% to 63.2% in patients with PD-L1-negative tumors, with an association between PD-L1 status and ORR favoring patients with PD-L1-positive tumors (OR, 1.94; 95% CI, 1.47-2.56; P < .001). Median OS ranged from 8.4 to 24.1 months in patients with PD-L1-positive tumors and from 6.0 to 19.1 months in patients with PD-L1-negative tumors. The pooled HR showed a significant reduction for patients with PD-L1-positive tumors compared with those with PD-L1-negative tumors in the risk of death (HR, 0.71; 95% CI, 0.57-0.89; P = .003) and risk of progression (HR, 0.55; 95% CI, 0.44-0.69; P < .001) when ICIs were administered. PD-L1 is not likely to be a predictive biomarker of ICI response. Conclusions and Relevance: This systematic review and meta-analysis suggests that PD-L1 expression is associated with improved ORR, OS, and PFS for patients with mUC who receive ICIs, but it is unlikely to be useful as a predictive biomarker. Developing predictive biomarkers is essential to select patients most likely to benefit from ICIs and avoid toxic effects and financial burden with these agents.

A neuroligin-2-YAP axis regulates progression of pancreatic intraepithelial neoplasia.

Pancreatic ductal adenocarcinoma (PDAC) is a tumor with a dismal prognosis that arises from precursor lesions called pancreatic intraepithelial neoplasias (PanINs). Progression from low- to high-grade PanINs is considered as tumor initiation, and a deeper understanding of this switch is needed. Here, we show that synaptic molecule neuroligin-2 (NLGN2) is expressed by pancreatic exocrine cells and plays a crucial role in the regulation of contact inhibition and epithelial polarity, which characterize the switch from low- to high-grade PanIN. NLGN2 localizes to tight junctions in acinar cells, is diffusely distributed in the cytosol in low-grade PanINs and is lost in high-grade PanINs and in a high percentage of advanced PDACs. Mechanistically, NLGN2 is necessary for the formation of the PALS1/PATJ complex, which in turn induces contact inhibition by reducing YAP function. Our results provide novel insights into NLGN2 functions outside the nervous system and can be used to model PanIN progression.

Financial Toxicity and Health-Related Quality of Life Profile of Patients With Hematologic Malignancies Treated in a Universal Health Care System.

PURPOSE: We investigated the association of financial toxicity (FT) with the health-related quality of life (HRQoL) profile of patients with hematologic malignancies treated in a universal health care system. METHODS: We did a secondary analysis of six multicenter studies enrolling patients with hematologic malignancies. FT was evaluated using the financial difficulties item of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Multivariable linear regression models were used to assess the mean differences in HRQoL scores between patients with or without FT, while adjusting for key potential confounding factors. We also examined the prevalence of clinically important problems and symptoms by the experience of FT, using established thresholds for the EORTC QLQ-C30. Multivariable binary logistic regression analysis was performed to explore the risk factors associated with FT. RESULTS: Overall, 1,847 patients were analyzed, of whom 441 (23.9%) reported FT. We observed statistically and clinically relevant worse scores for patients with FT compared with those without FT for all the EORTC QLQ-C30 scales. The three largest clinically relevant mean differences between patients with and without FT were observed in pain (∆ = 19.6 [95% CI, 15.7 to 23.5]; P < .001), social functioning (∆ = -18.9 [95% CI, -22.5 to -15.2]; P < .001), and role functioning (Δ = -17.7 [95% CI, -22.1 to -13.3]; P < .001). Patients with FT tended to report a higher prevalence of clinically important problems and symptoms across all EORTC QLQ-C30 scales. In the univariable and multivariable analyses, the presence of FT was associated with the presence of comorbidities, an Eastern Cooperative Oncology Group performance status ≥1, and not receiving a salary. CONCLUSION: Patients with hematologic malignancies treated in the setting of a universal health care system who experience FT have a worse HRQoL profile compared with those without FT.

Italian oncologists and vaccinations against infectious diseases: Results of a survey of the Italian Association of Medical Oncology.

BACKGROUND: Patients with cancer present a higher risk of vaccine-preventable diseases. Recommended vaccinations are the most cost-effective measure to reduce the risk of transmission and related complications. Nevertheless, vaccination rates are inadequate. Oncologists have a central role in tailored vaccine communication to their patients. We present the results of a survey conducted by AIOM in 2022, focusing on the perception of the problem by oncologists. MATERIALS AND METHODS: An anonymous 31-item online questionnaire was shared on 15 September 2022 on the AIOM website. The objectives of this survey were to examine the perception of Italian oncologists on vaccine-preventable diseases and the main available vaccines, their attitude towards recommending vaccines and the COVID-19 pandemic impact on their habits regarding vaccine-preventable diseases. RESULTS: Between September 2022 and January 2023, 114 medical oncologists (5% of the members) completed the anonymous questionnaire. At the first oncological visit, only 30% of respondents usually propose a vaccination schedule to all their patient, 41% do not usually discuss vaccinations at the first visit and 29% recommend vaccines exclusively to specific categories of patients. For 56% of respondents, patients are more aware of the benefits of vaccines, whereas 36% reported that patients are worried of receiving too many vaccines. CONCLUSION: This is the first survey conducted among Italian oncologists to better understand the perception and attitudes towards the vaccination. It highlights the urgent issues of educating and training oncologists in vaccine-preventable diseases and vaccine awareness and the need to build (or implement) a network of multidisciplinary collaborations.

The relationship among posttraumatic stress disorder, posttraumatic growth, and suicidal ideation among Italian healthcare workers during the first wave of COVID-19 pandemic.

OBJECTIVE: The COVID-19 pandemic impacted mental health across different groups, including healthcare workers (HWs). To date, few studies focused on potential positive aspects that may follow the exposure to the pandemic. We investigated the prevalence of posttraumatic stress disorder (PTSD) in Italian HWs and whether posttraumatic growth (PTG) dimensions affected the risk of suicidal ideation (SI) during the first COVID-19 wave. METHODS: An online self-report survey was conducted between April and May 2020. Sociodemographic data, information about COVID-19-related stressful events, Impact of the Event Scale-revised, and Post-Traumatic Growth Inventory-Short Form (PTGI-SF) scores were collected and compared between participants. Patient Health Questionnaire-9 scores were also collected to assess SI through item 9. Multivariate logistic regression was used to assess the relationship between PTGI and SI. RESULTS: Among 948 HWs, 257 (27.0%) reported a provisional PTSD diagnosis. The median PTGI-SF score was 24. Participants reporting PTSD symptoms had higher scores in the Spiritual change, Appreciation of life, and New possibilities domains, and in the total PTG scale. A total of 100 HWs (10.8%) screened positive for SI. Improvements in Relating to others domain of PTGI-SF (odds ratioOR: .46; 95% confidence interval: .25-.85) were associated with lower odds of SI. CONCLUSIONS: COVID-19 pandemic has been indicated as a risk factor for SI, also among HWs. PTG may have a protective role on suicide risk. Improvements in Relating to others domain reduced odds of SI, consistently with the role of loneliness and lack of connectedness with others in enhancing suicidal risk.

Meta-Analysis on the Combination of Chemotherapy With Programmed Death-Ligand 1 and Programmed Cell Death Protein 1 Blockade as First-Line Treatment for Unresectable Pleural Mesothelioma.

INTRODUCTION: Dual immune checkpoint blockers regimen represents a standard first-line therapy in unresectable pleural mesothelioma (PM). Novel combination strategies, including immune checkpoint blockers and antiangiogenic drugs, are currently under investigation in this setting. We aimed to assess the efficacy of the chemoimmunotherapy combination by reference to literature evidence. METHODS: A systematic review and meta-analysis of trials with first-line platinum-based chemotherapy associated with programmed death-ligand 1 and programmed cell death protein 1 agent in unresectable PM. We estimated the weighted summary proportion of disease response, along with the landmark probability of survival outcomes. RESULTS: A total of 349 patients with unresectable PM from four trials (DREAM, PrE0505, JME-001, and IND.227) were included, 79% (n = 274) with epithelioid and 21% (n = 75) with nonepithelioid histologic type. In aggregate, the objective response rate was 59.2% (95% confidence interval [CI]: 50.3%-67.9%) and disease control rate was 92.2% (95% CI: 89.2%-94.8%). Comparing epithelioid versus nonepithelioid tumors, the objective response rate was 64.5% versus 46.4%, (p < 0.001) and the disease control rate was 92.3% versus 80.0%, (p = 0.043), with an OR of 2.56 (95% CI: 1.51-4.32) for disease response and of 3.37 (95% CI: 0.99-11.47) for disease control. The aggregated estimated probability of progression-free survival was 63% (95% CI: 53%-71%) at 6 months and 25% (95% CI: 21%-31%) at 12 months, whereas the 6-, 12- and 24-month overall survival rates were 88% (95% CI: 81%-93%), 71% (95% CI: 61%-79%) and 39% (95% CI: 34%-45%), respectively. CONCLUSIONS: According to our analysis, first-line chemoimmunotherapy holds promise as a new treatment approach for PM, exhibiting encouraging survival outcomes and an enhanced response rate, including for the epithelioid subtype. Ongoing studies are necessary to establish its precise placement within the treatment algorithm.

Hematological Toxicity of PARP Inhibitors in Metastatic Prostate Cancer Patients with Mutations of BRCA or HRR Genes: A Systematic Review and Safety Meta-analysis.

BACKGROUND: PARP inhibitors (PARPis) are effective treatment options for patients with metastatic castration-resistant prostate cancer (mCRPC) as single agents or in combination with androgen receptor-targeted agents (ARTA). However, a clinically relevant adverse effect of these agents is hematological toxicity, a typical class adverse event (AE), which can lead to treatment modifications and discontinuations. OBJECTIVE: We aimed to analyze the risk of hematological AEs, including anemia, neutropenia, and thrombocytopenia secondary to PARPi treatments in mCRPC. PATIENTS AND METHODS: This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. We systematically searched the PubMed, EMBASE, and Cochrane databases, the American Society of Clinical Oncology (ASCO), and the European Society of Medical Oncology (ESMO) meeting abstracts for clinical trials concerning the use of PARPis, both as single agents and in combination, in patients with mCRPC. The search deadline was 30 June, 2023. We analyzed the pooled incidence of all grades of and ≥ G3 anemia, neutropenia, and thrombocytopenia. We subsequently calculated risk ratios (RRs) for all grades of and ≥ G3 AEs of PARPis versus non-PARPis from randomized clinical trials (RCTs). RESULTS: Eleven phase 2/3 trials with olaparib, niraparib, rucaparib, and talazoparib administered as single agents or combined with ARTA were selected. Anemia was the most common all grades (38.6%) and ≥ G3 AE (24.9%). In the analysis of relative risk, six RCTs were included. The administration of PARPis significantly increased the risk of developing all grades of anemia (RR = 2.44), neutropenia (RR = 3.15), and thrombocytopenia (RR = 4.66) compared with non-PARPis. Similarly, a significant increase in the risk of ≥ G3 anemia (RR = 5.73) and thrombocytopenia (RR = 5.44), and a not significant increased risk of neutropenia (RR = 3.41), were detected. CONCLUSIONS: In mCRPC, PARPis increase the risk of hematological toxicity compared with other treatments, both as single agents or combined with ARTA (high-quality evidence). Clinicians should be aware of this risk and the correct management, especially with the expected increased PARPis use in mCRPC.

Safety profile of darolutamide versus placebo: a systematic review and meta-analysis.

BACKGROUND: Darolutamide is an androgen receptor pathway inhibitor (ARPI) used in patients with prostate cancer (PC). In pivotal trials, it has demonstrated a favorable toxicity profile. There are no head-to-head comparison studies between the different ARPIs, but the efficacy of these drugs seems to be similar making the toxicity profile a key element for treatment selection. METHODS: We conducted a systematic review of all clinical trials assessing treatment with darolutamide for patients with PC using placebo as the control using the PubMed/Medline and Cochrane library databases. We also performed a meta-analysis to compare the safety of darolutamide versus placebo evaluating adverse events (AE) leading to treatment discontinuation and the rate of the AE reported as "AE of interest" in the ARAMIS trial. The comparison among darolutamide and the placebo group in terms of safety and tolerability was performed using odds ratio (OR) as meta-analytic outcome. RESULTS: We identified three articles comprising 2902 patients for the systematic review and meta-analysis (1652 treated with darolutamide and 1250 with placebo). Darolutamide did not increase AE leading to treatment discontinuation compared to placebo (pooled OR: 1.176, 95% CI 0.918-1.507, p = 0.633). Regarding the "AE of interest" there was no difference between darolutamide and placebo in terms of asthenia, cardiac arrhythmia, cardiac disorder, coronary artery disorder, depression mood disorder, falls, fatigue, heart failure, hot flushes, hypertension, mental-impairment disorder, rash, seizure and weight loss. The only "AE of interest" with a statistically significant difference in favor of placebo was bone fractures (pooled OR: 1.523, 95% CI 1.081-2.146). CONCLUSIONS: In our systematic review and meta-analysis, darolutamide showed a toxicity profile comparable to placebo with the exception of bone fractures. In the absence of head-to-head comparison studies between the different ARPIs, the results of our research suggest a preferred use of darolutamide in the approved settings.

Management of metastatic endometrial cancer: physicians' choices beyond the first line after approval of checkpoint inhibitors.

Introduction: Endometrial cancer (EC) represents 3.4% of all newly diagnosed cancer cases and is responsible for 2.1% of all cancer-related deaths. Approximately 10%-15% of women with EC are diagnosed with advanced-stage disease, resulting in a reported 5-year survival rate of only 17% for those with distant metastases. A better understanding of its molecular features has ushered in a new era of immunotherapy for the treatment of EC, allowing for alternative therapeutic approaches, even in cases of advanced disease. Methods: We administered a multi-choice online survey for Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) members. The questionnaire was available for 2 months, starting in October 2022. Our objective was to evaluate the current attitude of incorporating molecular characterization of EC into routine clinical practice, appraise the implementation of newly available therapies, and compare the outcomes with the previous survey conducted in April-May 2021 to ascertain the actual changes that have transpired during this recent time period. Results: The availability of molecular classification in Italian centers has changed in 1 year. Seventy-five percent of centers performed the molecular classification compared with 55.6% of the previous survey. Although this percentage has increased, only 18% performed all the tests. Significant changes have occurred in the administration of new treatments in EC patients in MITO centers. In 2022, 82.1% of the centers administrated dostarlimab in recurrent or advanced MMR-deficient (dMMR) EC experiencing disease progression after platinum-based chemotherapy regimens, compared to only 24.4% in 2021. In 2022, 85.7% of the centers already administrated the pembrolizumab plus lenvatinib combination as a second-line therapy for MMR-proficient (pMMR) patients with advanced or recurrent EC who had progressed from first-line platinum-based therapy. Conclusion: Both the therapeutic and diagnostic scenarios have changed over the last couple of years in MITO centers, with an increased prescription of immune checkpoint inhibitors and use of the molecular classification.
