Recent advances in squamous non-small cell lung cancer: evidence beyond predictive biomarkers
No full textSquamous non-small cell lung cancer (NSCLC) has always been characterized by a limited number of therapeutic options and by the lack of actionable biomarkers compared to its non-squamous counterpart. Recent clinical trials have led to the approval of new anti-neoplastic drugs available to both non-squamous and squamous NSCLC, consisting in a vascular-disrupting agent and two immune check-point inhibitors; additionally, a monoclonal antibody targeting the epidermal growth factor receptor (EGFR) is currently under evaluation by the Food and Drug Administration (FDA). While predictive molecular biomarkers have not been identified with consistency and are still highly demanded, these agents proved themselves noteworthy and can be considered a powerful addition to the available treatments for squamous NSCLC
Hematopoietic growth factors in lung cancer
No full textPurpose of review Most patients affected by lung cancer are treated with chemotherapy, and hence are at risk of myelosuppression. Hematopoietic growth factors have a relevant role in this setting, as they can improve quality of life, reduce the rate of chemotherapy-induced complications and allow the administration of full-dose chemotherapy. Recent findings Most data of hematologic growth factors in lung cancer come from dated publications or large trials involving different malignancies, thus limiting specific information for lung neoplasms. Nonetheless, most studies consistently identified myeloid growth factors as effective on specific end-points such as the duration and severity of neutropenia, or complications such as hospitalizations and febrile neutropenia; on the other hand, erythropoiesis-stimulating agents (ESAs) consistently improved anemia-specific end-points including hemoglobin values, transfusions rate and fatigue, although some specific safety issues characterized this drug class. The most recent international guidelines address these characteristics and include the main indications for hematologic growth factors in solid neoplasms, including lung cancer. Summary Myeloid growth factors and ESAs have a relevant role in selected patients undergoing chemotherapy for nonsmall cell lung cancer and small cell lung cancer. Notably, a comprehensive risk-benefit assessment is required in the specific case of ESAs

No full textTrastuzumab deruxtecan: Changing the destiny of her2 expressing solid tumors
No full textHER2 targeted therapies have significantly improved prognosis of HER2-positive breast and gastric cancer. HER2 overexpression and mutation is the pathogenic driver in non-small cell lung cancer (NSCLC) and colorectal cancer, however, to date, there are no approved HER2-targeted therapies with these indications. Trastuzumab deruxtecan (T-DXd) is a novel HER2-directed antibody drug conjugate showing significant anti-tumor activity in heavily pre-treated HER2-positive breast and gastric cancer patients. Preliminary data have shown promising objective response rates in patients with HER2-positive NSCLC and colorectal cancer. T-DXd has an acceptable safety profile, however with concerns regarding potentially serious treatment-emergent adverse events. In this review we focus on the pharmacologic characteristics and toxicity profile of T-Dxd, and provide an update on the most recent results of clinical trials of T-DXd in solid tumors. The referenced papers were selected through a PubMed search performed on 16 March 2021 with the following searching terms: T-DXd and breast cancer, or gastric cancer, or non-small cell lung cancer (NSCLC), or colorectal cancer. Oral presentation, abstracts, and posters presented at the American Society of Clinical Oncology (ASCO, Alexandria, VA, USA) 2020 and the European Society for Medical Oncology (ESMO, Lugano, Switzerland) 2020 annual meetings were retrieved for data on T-DXd. We also overview ongoing research and data of combination therapies currently under investigation, which will impact on future therapeutic strategies. Clinicaltrials.gov was searched to identify ongoing clinical trials of T-DXd alone or in combination in solid tumors
Circulating biomarkers of response and toxicity of immunotherapy in advanced non-small cell lung cancer (NSCLC): A comprehensive review
No full textImmune checkpoint inhibitors (ICIs) targeting the programmed cell death (PD)-1 protein and its ligand, PD-L1, and cytotoxic T-lymphocyte-associated antigen (CTLA)-4, have revolutionized the management of patients with advanced non-small cell lung cancer (NSCLC). Unfortunately, only a small portion of NSCLC patients respond to these agents. Furthermore, although immunotherapy is usually well tolerated, some patients experience severe immune-related adverse events (irAEs). Liquid biopsy is a non-invasive diagnostic procedure involving the isolation of circulating biomarkers, such as circulating tumor cells (CTC), cell-free DNA (cfDNA), and microRNAs (miRNAs). Thanks to recent advances in technologies, such as next-generation sequencing (NGS) and digital polymerase chain reaction (dPCR), liquid biopsy has become a useful tool to provide baseline information on the tumor, and to monitor response to treatments. This review highlights the potential role of liquid biomarkers in the selection of NSCLC patients who could respond to immunotherapy, and in the identification of patients who are most likely to experience irAEs, in order to guide improvements in care
Developing a risk assessment score for patients with cancer during the coronavirus disease 2019 pandemic
Full text linkThe novel coronavirus (CoV) pandemic is a serious threat for patients with cancer, who have an immunocompromised status and are considered at high risk of infections. Data on the novel CoV respiratory disease (coronavirus disease 2019 [COVID-19]) in patients with cancer are still limited. Unlike other common viruses, CoVs have not been shown to cause a more severe disease in immunocompromised subjects. Along with direct viral pathogenicity, in some individuals, CoV infection triggers an uncontrolled aberrant inflammatory response, leading to lung tissue damage. In patients with cancer treated with immunotherapy (e.g. immune checkpoint inhibitors), COVID-19 may therefore represent a serious threat. After a thorough review of the literature on CoV pathogenesis and cancer, we selected several shared features to define which patients can be considered at higher risk of COVID-19. We combined these clinical and laboratory variables, with the aim of developing a score to weight the risk of COVID-19 in patients with cancer
Novel treatment strategies for early-stage lung cancer: The oncologist’s perspective
No full textManagement of early-stage non-small cell lung cancer (NSCLC) consists in multimodal treatment, including surgery, radiotherapy and chemotherapy. The mainstay of treatment is radical surgery. Definitive radiotherapy using stereotactic techniques can provide adequate local disease control, and is the treatment of choice in medically inoperable patients. Most early-stage patients are at significant risk of disease relapse after local treatment. Adjuvant platinum-based chemotherapy has demonstrated to provide an absolute survival benefit of 5% compared to observation. However, unlike advanced/metastatic disease, little progress has been made in the treatment of early-stage NSCLC over the past decade. In recent years, plenty of research has focused on the optimization of adjuvant and neoadjuvant treatment. Several trials with novel drugs, such as targeted agents and immune-checkpoint inhibitors are currently underway, with preliminary positive results. Customization of treatment on patients’ characteristics before, and major pathological response after therapy, will further improve survival outcomes in this subset of patients
