Breast-cancer specific comprehensive archive of Patient-Reported Outcome Measures (PROMs) for clinical research and clinical practice in oncology: Results from the PRO4All project.

BACKGROUND: Inclusion of patient-reported outcomes (PROs) in oncology clinical trials is strongly recommended. However, selecting the most appropriate patient-reported outcome measures (PROMs) is not easy. This study aimed to develop a breast cancer (BC) specific comprehensive archive of PROMs. METHODS: As part of the PRO4All project, we identified available PROMs in oncology by searching facit.org, eortc.org, eprovide.mapi-trust.org, PubMed, ema.europa.eu (European Public Assessment Reports) and published reviews. For this analysis, only BC tools were extracted. We described information about PROM name, type of questionnaire, questionnaire variant(s), recall period, number of items, and presence of minimum clinically important difference (MCID) reference in literature. Then, we assigned each item to a specific domain according to a predefined taxonomy of 38 items for outcome classification. RESULTS: We identified and analyzed 383 PROMs. Of these, 29 were BC specific, but 2 were excluded because the questionnaires description was not available. 6 (22.2 %) were variants of another questionnaire. All questionnaires were self-reported. In 6 cases (22.2 %) the recall period to consider was the "last week". The mean number of items per questionnaire was 25.81 (range 6-71). 602 items were assigned to an outcome domain: emotional functioning/wellbeing in 26.6 % of cases, physical functioning in 14.1 %, delivery of care in 10.8 %, and general outcomes in 10.5 %. MCID reference was found only in 4 (14.8 %) cases. CONCLUSIONS: The newly developed archive represents a useful tool to optimize the use of PROMs in the evaluation of treatments in BC patients, promoting a patient-centered approach both in clinical research and practice.

The EXcellenT Trial: Exercise in Extended Oncogene Addicted Lung Cancer in Active Treatment.

INTRODUCTION: The discovery of oncogenic mutations that drive the growth and progression of Non-small-cell lung cancer (NSCLC) led to the development of a range of molecular targeted therapies. Tyrosine kinase inhibitors (TKIs) improve the overall outcome of patients with oncogene addicted NSCLC, ensure a better compliance to treatment and few side effects compared to traditional chemotherapy. However, the treatment is still completely "drug-centric", in a population of patients who usually survive for a long time and desire to regain their quality of life. Despite an extensive literature on the importance of complementary treatments and lifestyle promotion, the guidelines on physical exercise are general and usually refer to the entire lung cancer pathology. METHODS AND OBJECTIVES: EXcellenT is an Italian monocentric randomized prospective study enrolling 40 patients diagnosed with oncogene-addicted advanced NSCLC in active treatment with TKIs. Patients will be randomized (1:1 ratio) to an 'interventional' or a 'control' group. In the interventional arm (arm A), participants will receive a 3-month multicomponent personalized physical activity prescription combining a supervised coaching program at the training center and an app-based physical activity schedule at patients home. In the control group (arm B) patients will receive a fitness professional-guided montly session that will result in an unsupervised home-based physical activity counselling. Prospective collection of blood metabolome and immune phenotypes will be performed to investigate the integration with genetic alterations that drive the patient's disease. The overall aim of the project is to evaluate if a tailored physical program may have a significant impact on quality of life and performances of this specific homogeneous subgroup of patients. The exploratory goal is to elucidate a potential link between metabolites, immune parameters and genetic deregulations and how this interplay may be influenced by physical exercise. CONCLUSION: EXcellent trial aims to propose a new approach to personalized medicine in the specific subgroup of oncogene-addicted NSCLC patients, where targeted therapy is integrated with an equally tailored physical activity program. The homogeneity of this cancer population will provide insights on the influence of exercise on metabolism and immunity during treatment with TKIs.

Redetermination of PD-L1 expression after chemio-radiation in locally advanced PDL1 negative NSCLC patients: retrospective multicentric analysis.

Background: Chemoradiation therapy (CRT) is the treatment of choice for locally advanced non-small cell lung cancer (LA-NSCLC). Several clinical trials that combine programmed cell death 1 (PD1) axis inhibitors with radiotherapy are in development for patients with LA-NSCLC. However, the effect of CRT on tumor cells programmed cell death ligand-1 (PD-L1) expression is unknown. Methods: In this multicentric retrospective study, we analyzed paired NSCLC specimens that had been obtained pre- and post-CRT. PD-L1 expression on tumor cells was studied by immunohistochemistry. The purpose of this study was to evaluate the feasibility, risk of complications, and clinical relevance of performing re-biopsy after CRT in patients with PD-L1 negative LA-NSCLC. Results: Overall, 31 patients from 6 centers with PD-L1 negative LA-NSCLC were analyzed. The percentage of tumor cells with PD-L1 expression significantly increased between pre- and post-CRT specimens in 14 patients (45%). Nine patients had unchanged PD-L1 expression after CRT, in five patients the rebiopsy material was insufficient for PD-L1 analysis and in two patients no tumor cells at rebiopsy were found. The post-rebiopsy complication rate was very low (6%). All patients with positive PD-L1 re-biopsy received Durvalumab maintenance after CRT, except one patient who had a long hospitalization for tuberculosis reactivation. Median PFS of patients with unchanged or increased PD-L1 expression was 10 and 16.9 months, respectively. Conclusion: CRT administration can induce PD-L1 expression in a considerable fraction of PD-L1 negative patients at baseline, allowing them receiving the maintenance Durvalumab in Europe. Hence, after a definitive CRT, PD-L1 redetermination should be considered in patients with LA-NSCLC PD-L1 negative, to have a better selection of maintenance Durvalumab candidates.

APOLLO 11 Project, Consortium in Advanced Lung Cancer Patients Treated With Innovative Therapies: Integration of Real-World Data and Translational Research.

INTRODUCTION: Despite several therapeutic efforts, lung cancer remains a highly lethal disease. Novel therapeutic approaches encompass immune-checkpoint inhibitors, targeted therapeutics and antibody-drug conjugates, with different results. Several studies have been aimed at identifying biomarkers able to predict benefit from these therapies and create a prediction model of response, despite this there is a lack of information to help clinicians in the choice of therapy for lung cancer patients with advanced disease. This is primarily due to the complexity of lung cancer biology, where a single or few biomarkers are not sufficient to provide enough predictive capability to explain biologic differences; other reasons include the paucity of data collected by single studies performed in heterogeneous unmatched cohorts and the methodology of analysis. In fact, classical statistical methods are unable to analyze and integrate the magnitude of information from multiple biological and clinical sources (eg, genomics, transcriptomics, and radiomics). METHODS AND OBJECTIVES: APOLLO11 is an Italian multicentre, observational study involving patients with a diagnosis of advanced lung cancer (NSCLC and SCLC) treated with innovative therapies. Retrospective and prospective collection of multiomic data, such as tissue- (eg, for genomic, transcriptomic analysis) and blood-based biologic material (eg, ctDNA, PBMC), in addition to clinical and radiological data (eg, for radiomic analysis) will be collected. The overall aim of the project is to build a consortium integrating different datasets and a virtual biobank from participating Italian lung cancer centers. To face with the large amount of data provided, AI and ML techniques will be applied will be applied to manage this large dataset in an effort to build an R-Model, integrating retrospective and prospective population-based data. The ultimate goal is to create a tool able to help physicians and patients to make treatment decisions. CONCLUSION: APOLLO11 aims to propose a breakthrough approach in lung cancer research, replacing the old, monocentric viewpoint towards a multicomprehensive, multiomic, multicenter model. Multicenter cancer datasets incorporating common virtual biobank and new methodologic approaches including artificial intelligence, machine learning up to deep learning is the road to the future in oncology launched by this project.

Clinical evidence and adverse event management update of patients with RET- rearranged advanced non-small-cell lung cancer (NSCLC) treated with pralsetinib.

Current non-small cell lung cancer (NSCLC) management relies on genome-driven precision oncology thus shifting treatment paradigm towards biomarker-guided tumor-agnostic approaches. Recently, rearranged during transfection (RET) has been endorsed as tissue-agnostic target with sensitivity to RET inhibition. There are currently two selective RET tyrosine kinase inhibitors, pralsetinib and selpercatinib. The recent introduction of pralsetinib in the treatment algorithm of RET-rearranged tumor along with the mounting clinical evidence of pralsetinib durable activity from both randomized and observational studies holds the potential to disclose new avenues in the management of RET fusion positive NSCLC patients. Our narrative review aims to discuss the available clinical evidence on pralsetinib efficacy, particularly on brain metastases, and tolerability profile. In addition, our work explores the relevance of detecting RET fusions upfront in the disease history of patients with NSCLC.

Clinicopathological Features of Non-Small Cell Lung Carcinoma with BRAF Mutation.

(1) Background: BRAF mutations affect 4-5% of lung adenocarcinomas. This study aimed to analyze the clinicopathological features of lung carcinomas with BRAF mutations, focusing on V600E vs. non-V600E and the presence of co-mutations. (2) Methods: All BRAF-mutated lung carcinomas were retrieved from a molecular diagnostic unit (the reference unit for four different hospitals). The samples were analyzed using next-generation sequencing. Statistical analyses included log-rank tests for overall survival (OS) and progression-free survival (PFS). (3) Results: In total, 60 BRAF-mutated lung carcinomas were retrieved: 24 (40.0%) with V600E and 36 (60.0%) with non-V600E mutations, and 21 (35.0%) with other co-mutations and 39 (65.0%) with only BRAF mutations. Survival data were available for 54/60 (90.0%) cases. Targeted therapy was documented in 11 cases. Patients with V600E mutations exhibited a better prognosis than patients with non-V600E mutations (p = 0.008 for OS, p = 0.018 for PFS); this was confirmed in PFS (p = 0.036) when considering only patients who received no targeted therapy. Patients with co-mutations displayed no prognostic difference compared to patients carrying only BRAF mutations (p = 0.590 for OS, p = 0.938 for PFS). (4) Conclusions: BRAF-mutated lung carcinomas with V600E (40.0%) had a better prognosis than those without V600E. Concomitant co-mutations (35.0%) did not affect the prognosis.

New options and open issues in the management of unresectable stage III and in early-stage NSCLC: A report from an expert panel of Italian medical and radiation oncologists - INTERACTION group.

IMPORTANCE: After the PACIFIC trial, concurrent chemo-radiotherapy followed by consolidation therapy with durvalumab for 1 year (limited to PD-L1 tumour proportion score ≥ 1% in the EMA region) is the firmly established standard of care treatment for unresectable NSCLC patients. Several relevant questions are emerging with the growing use of this approach, posing novel challenges in clinical practice. Treatment of oncogene-addicted NSCLCs, management of mediastinal disease recurrence after surgery and the optimal management of patients progressing during or after durvalumab are now some of the most clinically relevant issues. OBSERVATIONS: Patients with unresectable NSCLC harbouring EGFR and HER2 mutations or ALK/ROS1/RET /NTRK1,2,3 rearrangements are unresponsive to immunotherapy. Importance of knowing the tumour genotyping (NGS, preferable DNA and RNA) from the earliest stages of NSCLC, also for the possible use of immunotherapy both in the adjuvant and perioperative setting. In case of mediastinal disease recurrence after surgery, re-biopsy is essential to re-determine the histological and biological characteristics of the disease and the distinction of recurrence in curable and non-curable disease is of pivotal important for the optimal management of subsequent treatments. CONCLUSIONS AND RELEVANCE: Treatment of stage III NSCLC has always been controversial and challenging: Multidisciplinary approach is mandatory and defining resectability is a critical issue. Chemo-radiotherapy followed by maintenance Durvalumab is now the standard of treatment. Herein, we provide a comprehensive overview of the key challenges and open questions that we are currently facing in clinical practice, in unresectable stage III and in early-stage NSCLC, identifying the knowledge gaps and the possible solutions.

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.

The role of next-generation sequencing in detecting gene fusions with known and unknown partners: a single-center experience with methodologies' integration.

AIMS: Next-generation sequencing (NGS) is becoming a new gold standard for determining molecular predictive biomarkers. This study aimed to evaluate the reliability of NGS in detecting gene fusions, focusing on comparing gene fusions with known and unknown partners. METHODS: We collected all gene fusions from a consecutive case series using an amplicon-based DNA/RNA NGS platform and subdivided them into two groups: gene fusions with known partners and gene fusions with unknown partners. Gene fusions involving ALK, ROS1 and RET were also examined by immunohistochemistry (IHC) and/or fluorescent in situ hybridization (FISH). RESULTS: Overall, 1174 malignancies underwent NGS analysis. NGS detected gene fusions in 67 cases (5.7%), further subdivided into 43 (64.2%) with known partners and 24 (35.8%) with unknown partners. Gene fusions were predominantly found in non-small cell lung carcinomas (52/67, 77.6%). Gene fusions with known partners frequently involved ALK (20/43, 46.5%) and MET (9/43, 20.9%), while gene fusions with unknown partners mostly involved RET (18/24, 75.0%). FISH/IHC confirmed rearrangement status in most (89.3%) of the gene fusions with known partners, but in only one (4.8%) of the gene fusions with unknown partners, with a significant difference (p < 0.001). In 17 patients undergoing targeted therapy, the log-rank test revealed that the overall survival was higher in the known partner group than in the unknown partner group (p = 0.002). CONCLUSIONS: NGS is a reliable method for detecting gene fusions with known partners, but it is less accurate in identifying gene fusions with unknown partners, for which further analyses (such as FISH) are required.

High Prevalence and Early Occurrence of Skeletal Complications in EGFR Mutated NSCLC Patients With Bone Metastases.

OBJECTIVES: The prevalence of Skeletal Related Adverse Events (SREs) in EGFR mutated non-small cell lung cancer (NSCLC) patients with bone metastases, treated with modern tyrosine kinase inhibitors (TKIs), has been scarcely investigated. MATERIALS AND METHODS: We retrospectively evaluated the data of EGFR mutated NSCLC patients with bone metastases treated with TKIs in 12 Italian centers from 2014 to 2019, with the primary aim to explore type and frequency of SREs. RESULTS: Seventy-seven out of 274 patients enrolled (28%) developed at least one major SRE: 55/274 (20%) bone fractures, 30/274 (11%) spinal cord compression, 5/274 (2%) hypercalcemia. Median time to the onset of SRE was 3.63 months. Nine patients (3%) underwent bone surgery and 150 (55%) radiation therapy on bone. SREs were more frequently observed within the 12 months from TKI start than afterwards (71 vs 29%, p 0.000). Patient Performance Status and liver metastases where independently associated with the risk of developing SREs. Median TKI exposure and overall survival were 11 and 28 months, respectively. Bone resorption inhibitors were associated with a lower risk of death (HR 0.722, 95% CI: 0.504-1.033, p = 0.075) although not statistically significant at multivariate analysis. CONCLUSION: Bone metastatic NSCLC patients with EGFR mutated disease, treated with EGFR TKIs, have a relatively long survival expectancy and are at high risk to develop SREs. The early SRE occurrence after the TKI start provides the rationale to administer bone resorption inhibitors.
