Tissue- and liquid-biopsy based NGS profiling in advanced non-small-cell lung cancer in a real-world setting: the IMMINENT study.

Introduction: To date, for all non-small cell lung cancer (NSCLC) cases, it is recommended to test for driver alterations to identify actionable therapeutic targets. In this light, comprehensive genomic profiling (CGP) with next generation sequencing (NGS) has progressively gained increasing importance in clinical practice. Here, with the aim of assessing the distribution and the real-world frequency of gene alterations and their correlation with patient characteristics, we present the outcomes obtained using FoundationOne (F1CDx) and FoundationLiquid CDx (F1L/F1LCDx) NGS-based profiling in a nationwide initiative for advanced NSCLC patients. Methods: F1CDx (324 genes) was used for tissue samples, and F1L (70 genes) or F1LCDx (324 genes) for liquid biopsy, aiming to explore the real-world occurrence of molecular alterations in aNSCLC and their relationship with patients' characteristics. Results: Overall, 232 advanced NSCLC patients from 11 Institutions were gathered [median age 63 years; never/former or current smokers 29.3/65.9%; adenocarcinoma/squamous 79.3/12.5%; F1CDx/F1L+F1LCDx 59.5/40.5%]. Alterations were found in 170 different genes. Median number of mutated genes per sample was 4 (IQR 3-6) and 2 (IQR 1-3) in the F1CDx and F1L/F1LCDx cohorts, respectively. TP53 (58%), KRAS (22%), CDKN2A/B (19%), and STK11 (17%) alterations were the most frequently detected. Actionability rates (tier I and II) were comparable: 36.2% F1CDx vs. 34% ctDNA NGS assays (29.5% and 40.9% F1L and F1LCDx, respectively). Alterations in KEAP1 were significantly associated with STK11 and KRAS, so as TP53 with RB1. Median tumor mutational burden was 6 (IQR 3-10) and was significantly higher in smokers. Median OS from metastatic diagnosis was 23 months (IQR 18.5-19.5) and significantly lower in patients harboring ≥3 gene mutations. Conditional three-year survival probabilities increased over time for patients profiled at initial diagnosis and exceeded those of individuals tested later in their clinical history after 12 months. Conclusion: This study confirms that NGS-based molecular profiling of aNSCLC on tissue or blood samples offers valuable predictive and prognostic insights.

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.

Pralsetinib in RET fusion-positive non-small-cell lung cancer: A real-world data (RWD) analysis from the Italian expanded access program (EAP).

OBJECTIVES: The selective RET-inhibitor pralsetinib has shown therapeutic activity in early clinical trials in patients with non-small cell lung cancer (NSCLC) harboring rearranged during transfection (RET) gene fusions. To date, the real-world efficacy of pralsetinib in this population is unknown. MATERIALS AND METHODS: A retrospective efficacy and safety analysis was performed on data from patients with RET-fusion positive NSCLC enrolled in the pralsetinib Italian expanded access program between July 2019 and October 2021. RESULTS: Overall, 62 patients with RET-fusion positive NSCLC received pralsetinib at 20 Italian centers. Next-generation sequencing was used to detect RET alterations in 44 patients (73 %). The most frequent gene fusion partner was KIF5B (75 % of 45 evaluable). Median age was 62 years (range, 36-90), most patients were female (57 %) and never smokers (53 %). Brain metastases were known in 18 patients (29.5 %) at the time of pralsetinib treatment. 13 patients were treatment naïve (unfit for chemotherapy), 48 were pretreated (median number of previous lines: 1, range, 1-4). The objective response rate (ORR) was 66 % [95 % confidence interval (CI), 53-81] in the evaluable population (n = 59). The disease control rate (DCR) was 79 %. After a median follow-up of 10.1 months, the median progression free survival was 8.9 months (95 %CI, 4.7-NA). In patients with measurable brain metastases (n = 6) intracranial ORR was 83 %, intracranial DCR was 100 %. Overall, 83.6 % of patients experienced any-grade treatment-related adverse events (TRAEs), 39 % grade 3 or greater (G ≥ 3). The most common G ≥ 3 TRAEs were neutropenia (9.8 %), dry mouth/oral mucositis (8.2 %), and thrombocytopenia (6.6 %). Seven patients (12 %) discontinued pralsetinib due to TRAEs, twenty-six had at least one dose level modification due to TRAEs. Two treatment-related deaths were observed (1 sepsis, 1 typhlitis). CONCLUSIONS: In the real-world setting, pralsetinib confirmed durable systemic activity and intracranial response in RET-fusion positive NSCLC. Toxicity profile was consistent with previous reports.

Current management of cancer pain in Italy: Expert opinion paper.

INTRODUCTION: Chronic pain and breakthrough cancer pain (BTcP) have a high prevalence in all cancer types and cancer stages, combined with a significant physical, psychological, and economic burden. Despite efforts to improve appropriate management of cancer pain, a poor assessment and guilty undertreatment are still reported in many countries. The purpose of this expert opinion paper is to contribute to reduce and clarify these issues with a multidisciplinary perspective in order to share virtuous paths of care. METHODS: Common questions about cancer pain assessment and treatment were submitted to a multidisciplinary pool of Italian clinicians and the results were subsequently discussed and compared with the findings of the published literature. CONCLUSION: Despite a dedicated law in Italy and effective treatments available, a low percentage of specialists assess pain and BTcP, defining the intensity with validated tools. Moreover, in accordance with the findings of the literature in many countries, the undertreatment of cancer pain is still prevalent. A multidisciplinary approach, more training programs for clinicians, personalised therapy drug formulations, and virtuous care pathways will be essential to improve cancer pain management.

[Precision medicine in rearranged ALK NSCLC: a case report.] / La medicina di precisione nel NSCLC ALK riarrangiato: un caso clinico.

Among solid tumors, non-small cell lung cancer (NSCLC) represents the paradigm of the application of precision medicine to clinical practice. Understanding many biomolecular mechanisms in the determinism of NSCLC has ensured the development of small molecules targeting specific genetic mutations with key roles in tumor disease progression. The ATLAS IALSC guidelines recommend carrying out screening for rearrangement of the ALK gene in all patients with advanced NSCLC, mainly for the histological type adenocarcinoma or with an adenocarcinoma component. The use of next generation sequencing (NGS) panels applied to liquid biopsy provides a powerful method for the genetic profiling of NSCLC for both standard treatment options and clinical trials. Liquid biopsy represents a powerful non-invasive methodology to provide clinically useful information in defining the therapeutic process of patients with translocated ALK NSCLC.

[Target therapies in translocated ALK lung cancer: treatment management in oncology center of Lazio.] / Target therapies nel tumore al polmone ALK-positivo: gestione del trattamento nei centri di oncologia del LazioIncontro di approfondimento e confronto sulla gestione dei pazienti e sulla strategia terapeutica nei carcinomi polmonari positivi al riarrangiamento di ALK.

Lung cancer is a disease extremely heterogeneous in the molecular aspect and knowing the mutational profile of patients is essential in order to initiate the most appropriate treatment. In 2018, alectinib was approved in Italy for the first-line treatment of patients with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC), becoming a new therapeutic option for this patient group which constitutes approximately 3-7% of patients with NSCLC. On October 26th a virtual meeting was held in which 10 clinicians from various oncology centers in Lazio took part on the management of therapy of patients with Alk translocation, directed by Dr. Maria Rita Migliorino. The aim of the meeting was to share their clinical experience and to provide a series of practical that can help clinicians during treatment with target therapies in ALK-positive NSCLC.

[Application of liquid biopsy in clinical practice: the importance of a scientific network for effective use of the biomolecular markers in NSCLC patient..] / Applicazione della biopsia liquida nella pratica clinica: l'importanza di un network scientifico per un efficace utilizzo dell'assetto biomolecolare nelle popolazioni affette da NSCLC.

The therapeutic approach to the patient with non-small cell lung cancer (NSCLC) has undergone, in the last decade, a profound revolution following the marketing of molecularly targeted drugs. The launch of a vast research activity with the use of next generation sequencing (NGS) applied to liquid biopsy should be underlined. This last methodology, which allows to identify the correct biomolecular structure of the neoplastic population, has achieved significant progress in the effective implementation of personalized medicine. Nevertheless, the liquid biopsy represents a useful diagnostic strategy in those patients in whom a rebiopsia is difficult for technical reasons or for the patient's health conditions. The liquid biopsy represents a substantial cultural revolution opening a scenario in the identification of molecular drivers in the treatment of lung neoplasms.

[Immunotherapy in non-small cell lung cancer patients: back to the future.] / L'immunoterapia nel tumore del polmone non a piccole cellule: ritorno al futuro.

With the advent of immunotherapy, the life expectancy of patients with advanced non-small cell lung cancer (NSCLC) is dramatically improved. As described in the most recent clinical trials, the addition of immunotherapy to the available therapeutic strategies, restoring an efficient immune response against neoplasms and establishing an immunological memory, is able to improve both patient's survival and quality of life. This paved the way for new therapeutic algorithms, new combination strategies, as well as the possible use of adoptive immunotherapy. Although the use of immunotherapy is now widely employed in the different phases of lung cancer, we have not yet fully understood what are both the actual mechanisms of action and resistance to checkpoint inhibitors, predictive factors of response, immuno-related response criteria, and interferences between immunotherapy and tumor microenvironment, as well as angiogenesis and its interactions with conventional therapies, such as chemotherapy. The objective of this critical review is to frame the relevant results obtained with immunotherapy in NSCLC, providing insights to help overcome decision-making for a better therapeutic choice. In addition, returning to the study of pulmonary physiology and preclinical data, we will address the new issues on the heterogeneity of response to anti-PD1/anti-PD-L1, including their combinations, in NSCLC. Moreover, to date, we are facing with patterns of response different from those previously seen with cytotoxic or target therapies. Indeed, different radiological evaluation criteria have been proposed to evaluate response to immunotherapy and further efforts are needed to identify a unique system of evaluation and other than PDL1 biomarkers, to integrate radiology in the assessment of response.

Eribulin in Male Patients With Breast Cancer: The First Report of Clinical Outcomes.

BACKGROUND: Evidence on the management and treatment of male breast cancer is scant. We report the analysis of a multicenter Italian series of patients with male breast cancer treated with eribulin. To our knowledge, this is the first report on the use or eribulin in this setting. PATIENTS AND METHODS: Patients were retrospectively identified in 19 reference centers. All patients received eribulin treatment, according to the standard practice of each center. Data on the identified patients were collected using a standardized form and were then centrally reviewed by two experienced oncologists. RESULTS: A total of 23 patients (median age, 64 years; range, 42-80) were considered. The median age at the time of diagnosis of breast cancer was 57 years (range, 42-74). HER2 status was negative in 14 patients (61%), and 2 patients (9%) had triple-negative disease. The most common metastatic sites were the lung (n = 14; 61%) and bone (n = 13; 56%). Eribulin was administered for a median of 6 cycles (range, 3-15). All patients reported at least stable disease; two complete responses (9%) were documented. Eribulin was well-tolerated, with only four patients (17%) reporting grade 3 adverse events and two (9%) with treatment interruptions because of toxicity. Eight subjects (35%) did not report any adverse event during treatment. For patients with a reported fatal event, the median overall survival from the diagnosis of metastatic disease was 65 months (range, 22-228). CONCLUSION: Although hampered by all the limitations of any retrospective case series, the results of the present study suggest, for the first time, the use of eribulin as therapy for male breast cancer. IMPLICATIONS FOR PRACTICE: Evidence on the management and treatment of male breast cancer is eagerly awaited. Although hampered by all the limitations of any retrospective case series, the results of the present study suggest, for the first time, the use of eribulin as therapy for male breast cancer.

The changes of lipid metabolism in advanced renal cell carcinoma patients treated with everolimus: a new pharmacodynamic marker?

BACKGROUND: Everolimus is a mammalian target of rapamycin (mTOR) inhibitor approved for the treatment of metastatic renal cell carcinoma (mRCC). We aimed to assess the association between the baseline values and treatmentrelated modifications of total serum cholesterol (C), triglycerides (T), body mass index (BMI), fasting blood glucose level (FBG) and blood pressure (BP) levels and the outcome of patients treated with everolimus for mRCC. METHODS: 177 patients were included in this retrospective analysis. Time to progression (TTP), clinical benefit (CB) and overall survival (OS) were evaluated. RESULTS: Basal BMI was significantly higher in patients who experienced a CB (p=0,0145). C,T and C+T raises were significantly associated with baseline BMI (p=0.0412, 0.0283 and 0.0001). Median TTP was significantly longer in patients with T raise compared to patients without T (10 vs 6, p=0.030), C (8 vs 5, p=0.042) and C+T raise (10.9 vs 5.0, p=0.003). At the multivariate analysis, only C+T increase was associated with improved TTP (p=0.005). T raise (21.0 vs 14.0, p=0.002) and C+T increase (21.0 vs 14.0, p=0.006) were correlated with improved OS but were not significant at multivariate analysis. CONCLUSION: C+T raise is an early predictor for everolimus efficacy for patients with mRCC.

Use of biosimilar epoetin to increase hemoglobin levels in patients with chemotherapy-induced anemia: real-life clinical experience.

AIM: To evaluate the effectiveness of a biosimilar erythropoiesis-stimulating agent (Binocrit) for the treatment of patients with cancer and chemotherapy-induced anemia in real-life clinical practice. MATERIALS & METHODS: Data were collected retrospectively from patients at five European centers (in France, Italy, The Netherlands, Romania and Spain) who received treatment with Binocrit. Hemoglobin (Hb) levels were recorded at regular intervals during Binocrit therapy for up to 26 weeks. Hb response (an increase of ≥ 1 g/dl in 4 weeks or a Hb level in the range 10-12 g/dl during the study) was assessed in patients with a Hb level ≥ 8.5 g/dl at the start of therapy who received treatment for at least 6 weeks. Hb response rates in patients who did and did not receive intravenous (iv.) iron were also assessed, and data on any serious unexpected adverse events were collected. RESULTS: Among evaluable patients (n = 113), 79% achieved a Hb response. Response rates were similar among evaluable patients who received an initial Binocrit dose of 30,000 or 40,000 IU/week (81 vs 78%; p = not significant). The Hb response rate was significantly greater in patients who received iv. iron than in patients who did not receive iv. iron (93 vs 77%; p < 0.05). No serious unexpected adverse events were reported. CONCLUSION: Use of the biosimilar erythropoiesis-stimulating agent Binocrit is effective and safe for the treatment of patients with cancer and chemotherapy-induced anemia. Supplementation with iv. iron increases the response rate compared with oral or no iron supplementation.

[Pemetrexed monotherapy in previously treated patients with advanced non small cell lung cancer; differences by histology. Our experience]. / Monoterapia con pemetrexed in pazienti pretrattati affetti da carcinoma polmonare non a piccole cellule in fase avanzata: impatto dell'istologia. Nostra esperienza.

Emerging data suggest pemetrexed is active in patients with adenocarcinoma of lung compared to those with squamous cell carcinoma. We retrospectively reviewed advanced non small cell lung cancer (NSCLC) patients previously treated, analysing efficacy on histologic characteristics. From January 2007 to December 2010, 25 patients with stage IIIB or IV NSCLC (17 with adenocarcinoma and 8 with squamous cell carcinoma), who had previously failed on platinum-based chemotherapy, received pemetrexed 500 mg/mq every 3 weeks until disease progression or unacceptable toxicities. Analysing the histologic subgroups we observed 1 (5.9%) complete response, partial response in 5 patients (29.4%), stable disease in 6 (35.3%), progression disease in 5 (29.4%) in adenocarcinoma group compared to 4 (50%) stable disease and 4 (50%) progression disease in squamous cell carcinoma group. Median progression free survival was 8 months (range 3-22) for adenocarcinoma patients and 4 months (range 2-6) for squamous cell patients. According to data of the literature, also our small retrospective study conducted on unselected patients confirms the difference of pemetrexed efficacy by histology type, with better results in patients with adenocarcinoma lung cancer.

Long-term survival of metastatic melanoma to the ileum with evidence of primary cutaneous disease after 15 years of follow-up: a case report.

The small bowel is the most common site of gastrointestinal metastasis from cutaneous melanoma. Malignant melanoma has a poor prognosis, especially if distant metastases appear. Although rare primary melanoma of the small bowel has been described, more frequently these lesions originate from unknown cutaneous melanoma. Here we report the case of a 58-year-old man with a diagnosis of melanoma of the ileum without evidence of primary cutaneous disease. After 15 years, during the clinical and radiological follow-up, a cutaneous melanoma in the left parietal side of the scalp, probably corresponding to the primary lesion with abdominal node metastasis, was diagnosed. After 6 months of chemotherapy with fotemustine, the patient showed a complete response. At present, he is still alive 18 years after the diagnosis of intestinal metastasis.

A study of the humoral immune response of breast cancer patients to a panel of human tumor antigens identified by phage display.

OBJECTIVE: In this article we provide evidence of a significant spontaneous humoral response in cancer patients. METHODS: A panel of tumor-associated antigens, previously identified through serological screening of phage-displayed cDNA libraries from solid human tumors, breast carcinoma cell lines and human testis by employing breast cancer patient sera, was used in this study to survey sera from 182 patients with known disease histories and clinical stages. RESULTS: This analysis reveals a statistically significant association between tumor disease and presence in peripheral blood of IgG antibodies against four autoantigens. One of these antigens (D7-1) is particularly interesting in that the antibody response against it grows with cancer progression from stages I through IV, with an incidence of 13.2, 13.5, 18.2 and 27%, respectively. The significance of this stage-dependent increase in the incidence is confirmed by the Mantel-Haenszel Chi-squared test (P=0.001). CONCLUSIONS: Our data confirm association between breast cancer diagnosis of patients and presence in their peripheral blood of antibodies against several autoantigens identified by phage display.

Identification of a panel of tumor-associated antigens from breast carcinoma cell lines, solid tumors and testis cDNA libraries displayed on lambda phage.

BACKGROUND: Tumor-associated antigens recognized by humoral effectors of the immune system are a very attractive target for human cancer diagnostics and therapy. Recent advances in molecular techniques have led to molecular definition of immunogenic tumor proteins based on their reactivity with autologous patient sera (SEREX). METHODS: Several high complexity phage-displayed cDNA libraries from breast carcinomas, human testis and breast carcinoma cell lines MCF-7, MDA-MB-468 were constructed. The cDNAs were expressed in the libraries as fusion to bacteriophage lambda protein D. Lambda-displayed libraries were efficiently screened with sera from patients with breast cancer. RESULTS: A panel of 21 clones representing 18 different antigens, including eight proteins of unknown function, was identified. Three of these antigens (T7-1, T11-3 and T11-9) were found to be overexpressed in tumors as compared to normal breast. A serological analysis of the 21 different antigens revealed a strong cancer-related profile for at least five clones (T6-2, T6-7, T7-1, T9-21 and T9-27). CONCLUSIONS: Preliminary results indicate that patient serum reactivity against five of the antigens is associated with tumor disease. The novel T7-1 antigen, which is overexpressed in breast tumors and recognized specifically by breast cancer patient sera, is potentially useful in cancer diagnosis.

Atrial fibrillation during adjuvant chemotherapy with docetaxel: a case report.

A 46-year-old woman had an episode of atrial fibrillation during infusion of docetaxel as adjuvant chemotherapy for an infiltrating ductal carcinoma of the breast. All cardiological tests performed before treatment were normal and there was no evidence of thyroid dysfunction nor any objective or anamnestic data indicating acute or chronic cardiovascular disease. None of the drugs administered has ever shown any proarrhythmic activity. In controlled clinical trials docetaxel was found to have a very low cardiotoxicity.
