Neoadjuvant immunotherapy strategies for resectable non-small cell lung cancer (NSCLC): Current evidence among special populations and future perspectives.

About one third of patients with Non-Small Cell Lung Cancer (NSCLC) presents at diagnosis with localized or locally advanced disease amenable to curative surgical resection. Surgical operability refers to stage I to IIIA and selected stage IIIB NSCLC. One of the main challenges in the management of early-stage resectable NSCLC is the optimization of available therapeutic strategies to prevent local and distant disease relapse, thus improving survival outcomes.

Sotorasib in KRASp.G12C mutated advanced NSCLC: Real-world data from the Italian expanded access program.

Background: Sotorasib showed a significant improvement of progression free survival (PFS), safety and quality of life over docetaxel in patients with KRASp.G12C-mutated advanced non-small-cell lung cancer (NSCLC) within the CodeBreak-200 study. Here we report real-world efficacy and tolerability data from NSCLC patients who received sotorasib within the Italian expanded access program (EAP).

The Molecular Tumor Board of the Regina Elena National Cancer Institute: from accrual to treatment in real-world.

Background: Molecular Tumor Boards (MTB) operating in real-world have generated limited consensus on good practices for accrual, actionable alteration mapping, and outcome metrics. These topics are addressed herein in 124 MTB patients, all real-world accrued at progression, and lacking approved therapy options.

Methods: Actionable genomic alterations identified by tumor DNA (tDNA) and circulating tumor DNA (ctDNA) profiling were mapped by customized OncoKB criteria to reflect diagnostic/therapeutic indications as approved in Europe.

Pretreated / Lung Adenocarcinoma With Leptomeningeal Disease Achieving Long-Lasting Disease Control on Osimertinib, Dabrafenib, and Trametinib: A Case Report.

Oncogene-addicted NSCLC inevitably becomes resistant to targeted therapy by developing acquired resistance through on- or off-target mechanisms, potentially detectable by liquid biopsy. We present the first reported case of a patient with pretreated / lung adenocarcinoma and symptomatic leptomeningeal metastasis obtaining durable clinical benefit on osimertinib, dabrafenib, and trametinib treatment.

ALK rearrangement is an independent predictive factor of unexpected nodal metastasis after surgery in early stage, clinical node negative lung adenocarcinoma.

Objectives: Despite notable advances made in preoperative staging, unexpected nodal metastases after surgery are still significantly detected. Given the promising role of neoadjuvant targeted treatments, the definition of novel predictive factors of nodal metastases is an extremely important issue. In this study we aim to analyze the upstaging rate in patients with early stage NSCLC without evidence of nodal disease in the preoperative staging who underwent lobectomy and radical lymphadenectomy.

Combi-TED: a new trial testing Tedopi with docetaxel or nivolumab in metastatic non-small-cell lung cancer progressing after first line.

Despite the positive results obtained by first-line chemoimmunotherapy in patients with metastatic non-small-cell lung cancer (NSCLC), only a few second-line options are available after disease progression. Combi-TED is a phase II international study that will assess the efficacy of Tedopi, a cancer vaccine, combined with either docetaxel or nivolumab and compared with docetaxel monotherapy in patients with metastatic NSCLC after chemoimmunotherapy. The study, currently in the recruitment phase, will assess 1-year overall survival (primary end point), patient's progression-free survival and overall response rate, as well as the correlation of efficacy with several tumor or blood biomarkers.

Prognosis of ALK-rearranged non-small-cell lung cancer patients carrying TP53 mutations.

Non-small-cell lung cancer (NSCLC) is the primary cause of cancer-related death. Gene rearrangements involving the anaplastic lymphoma kinase (ALK) tyrosine kinase identify a clinical and molecular subset of NSCLC patients, who benefit from the monotherapy with ALK tyrosine kinase inhibitors. Nonetheless, responsiveness to TKIs and prognosis of these patients are influenced by several factors, including resistance mechanisms and mutations affecting genes involved in key molecular pathways of cancer cells.

[Management of small cell lung cancer patient in the regions of Lazio, Umbria and Sardinia.].

Small cell lung cancer (SCLC) is an aggressive disease, difficult to treat. There have been no significant therapeutic advances over platinum and etoposide chemotherapy in the last 20 years until the introduction of immunotherapy. In 2020 atezolizumab, an immune checkpoint inhibitor against PD-L1 was approved in Italy in combination with carboplatin and etoposide for the first-line treatment of patients with extensive stage disease (ES-SCLC), becoming the new standard treatment.

Predictive ability of a drug-based score in patients with advanced non-small-cell lung cancer receiving first-line immunotherapy.

Background: We previously demonstrated the cumulative poor prognostic role of concomitant medications on the clinical outcome of patients with advanced cancer treated with immune checkpoint inhibitors, creating and validating a drug-based prognostic score to be calculated before immunotherapy initiation in patients with advanced solid tumours. This 'drug score' was calculated assigning score 1 for each between proton-pump inhibitor and antibiotic administration until a month before cancer therapy initiation and score 2 in case of corticosteroid intake. The good risk group included patients with score 0, intermediate risk with score 1-2 and poor risk with score 3-4.

Differential influence of antibiotic therapy and other medications on oncological outcomes of patients with non-small cell lung cancer treated with first-line pembrolizumab versus cytotoxic chemotherapy.

Background: Some concomitant medications including antibiotics (ATB) have been reproducibly associated with worse survival following immune checkpoint inhibitors (ICIs) in unselected patients with non-small cell lung cancer (NSCLC) (according to programmed death-ligand 1 (PD-L1) expression and treatment line). Whether such relationship is causative or associative is matter of debate.

Methods: We present the outcomes analysis according to concomitant baseline medications (prior to ICI initiation) with putative immune-modulatory effects in a large cohort of patients with metastatic NSCLC with a PD-L1 expression ≥50%, receiving first-line pembrolizumab monotherapy.

Smoking status during first-line immunotherapy and chemotherapy in NSCLC patients: A case-control matched analysis from a large multicenter study.

Background: Improved outcome in tobacco smoking patients with non-small cell lung cancer (NSCLC) following immunotherapy has previously been reported. However, little is known regarding this association during first-line immunotherapy in patients with high PD-L1 expression. In this study we compared clinical outcomes according to the smoking status of two large multicenter cohorts.

Bone metastases and immunotherapy in patients with advanced non-small-cell lung cancer.

Background: Bone metastases (BoM) are a negative prognostic factor in non-small-cell lung cancer (NSCLC). Beyond its supportive role, bone is a hematopoietic organ actively regulating immune system. We hypothesized that BoM may influence sensitivity to immunotherapy.

Crizotinib in -Deregulated or -Rearranged Pretreated Non-Small Cell Lung Cancer (METROS): A Phase II, Prospective, Multicenter, Two-Arms Trial.

Purpose: -deregulated NSCLC represents an urgent clinical need because of unfavorable prognosis and lack of specific therapies. Although recent studies have suggested a potential role for crizotinib in patients harboring amplification or exon 14 mutations, no conclusive data are currently available. This study aimed at investigating activity of crizotinib in patients harboring or alterations.

Programmed death ligand 1 expression in early stage, resectable non-small cell lung cancer.

Introduction: For several years non-small cell lung cancer (NSCLC) has been considered non-immunogenic. Recent advances in antitumor immunity brought to the discovery of checkpoints that modulate immune response against cancer. One of them is programmed death receptor 1 (PD-1) and its ligand (PD-L1).

Circulating programmed death ligand-1 (cPD-L1) in non-small-cell lung cancer (NSCLC).

Background: This study aimed at investigating feasibility of programmed death ligand-1 (PD-L1) testing in plasma samples of advanced NSCLC patients receiving first-line treatment, assessing whether circulating (c)PD-L1 levels were modified by the therapy and whether baseline cPD-L1 levels were associated with patients' clinical responses and survival outcome.

Methods: Peripheral blood samples were collected from 16 healthy volunteers and 56 newly diagnosed NSCLC patients before and at 12th week during the course of first-line therapy. The level of PD-L1 was measured in plasma samples using the human (PD-L1/CD274) ELISA kit (CUSABIO, MD, USA).

Patterns of Care and Clinical Outcomes of HER2-positive Metastatic Breast Cancer Patients With Newly Diagnosed Stage IV or Recurrent Disease Undergoing First-line Trastuzumab-based Therapy: A Multicenter Retrospective Cohort Study.

Background: The aim of the study was to compare the patterns of care and clinical outcomes of HER2-positive metastatic breast cancer (MBC) patients with de novo or recurrent disease who underwent first-line trastuzumab-based therapy.

Patients And Methods: This was a multicenter retrospective cohort study including consecutive patients with HER2-positive MBC who received first-line trastuzumab-based therapy. Analyses on treatment response and effectiveness were conducted according to type of metastatic presentation (ie, de novo vs.

microRNA classifiers are powerful diagnostic/prognostic tools in ALK-, EGFR-, and KRAS-driven lung cancers.

microRNAs (miRNAs) can act as oncosuppressors or oncogenes, induce chemoresistance or chemosensitivity, and are major posttranscriptional gene regulators. Anaplastic lymphoma kinase (ALK), EGF receptor (EGFR), and V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) are major drivers of non-small cell lung cancer (NSCLC). The aim of this study was to assess the miRNA profiles of NSCLCs driven by translocated ALK, mutant EGFR, or mutant KRAS to find driver-specific diagnostic and prognostic miRNA signatures.

Current and Emerging Options in the Management of EGFR Mutation-Positive Non-Small-Cell Lung Cancer: Considerations in the Elderly.

The elderly population with cancer is increasing worldwide. Currently, the median age at lung cancer diagnosis is approximately 70 years. Clinicians are increasingly dealing with a population of elderly non-small-cell lung cancer patients characterised by relevant co-morbidities and ageing-related characteristics, making treatment choice more challenging.
