Antibody-drug conjugates in advanced lung cancer: Is this a new frontier?

Over the past decade, the lung cancer landscape has been dominated by targeted and immunotherapeutic approaches that have drastically shifted treatment paradigms for patients with advanced non-small cell lung cancer (NSCLC). Despite these scientific and clinical advances, there are still many unmet needs underscoring the importance of novel strategies. Antibody-drug conjugates (ADCs) represent one such strategy that is beginning to alter the therapeutic strategies for patients with advanced NSCLC.

Factors associated with worsening sexual function during adjuvant endocrine therapy in a prospective clinic-based cohort of women with early-stage breast cancer.

Purpose: Sexual function problems are common but under-reported among women receiving adjuvant endocrine therapy for breast cancer. Worsening scores on patient-reported outcomes (PROs) may identify those at risk for sexual function problems during treatment. We performed a secondary analysis of prospectively collected PROs in women receiving adjuvant endocrine therapy to identify factors associated with worsening sexual function.

Phase II study of afatinib plus pembrolizumab in patients with squamous cell carcinoma of the lung following progression during or after first-line chemotherapy (LUX-Lung-IO).

Introduction: Afatinib and pembrolizumab have separately shown survival benefit in patients with squamous cell carcinoma (SqCC) of the lung, and there is biological rationale for concurrent inhibition of the programmed death ligand-1 and epidermal growth factor receptor (EGFR) pathways in this patient population.

Materials And Methods: This open-label, single-arm study enrolled patients with SqCC of the lung who had progressed during/after first-line chemotherapy and comprised two parts: a safety run-in to establish the recommended phase II dose (RP2D; afatinib 40 mg or 30 mg once daily with pembrolizumab 200 mg every 3 weeks); and the main part assessing efficacy and safety of the RP2D. The primary endpoint was objective response rate (ORR); secondary endpoints included the RP2D, progression-free survival (PFS) and overall survival (OS).

Role of Platinums in Triple-Negative Breast Cancer.

Purpose Of Review: Platinum compounds are used in the treatment of various types of cancer. Here, we review the current role of cisplatin and carboplatin in the treatment of early stage and advanced triple-negative breast cancer (TNBC), and the use of biomarkers in predicting response to platinum therapy.

Recent Findings: Addition of carboplatin to a neoadjuvant chemotherapy regimen can result in improvement in the pathological complete response rates.

Clinico-pathologic features, treatment and outcomes of breast cancer during pregnancy or the post-partum period.

Purpose: Breast cancer during pregnancy (BC-P) or the first year post-partum (BC-PP) is rare and whether it differs from breast cancer (BC) in young women not associated with pregnancy is uncertain.

Methods: We queried our institutional database for BC-P and BC-PP cases and matched controls with BC not associated with pregnancy diagnosed between January 1, 1985 and December 31, 2013. We performed two parallel retrospective cohort studies evaluating clinico-pathologic features, treatment and outcomes for BC-P and BC-PP cases compared to their controls.

Lung Cancer Surveillance After Definitive Curative-Intent Therapy: ASCO Guideline.

Purpose: To provide evidence-based recommendations to practicing clinicians on radiographic imaging and biomarker surveillance strategies after definitive curative-intent therapy in patients with stage I-III non-small-cell lung cancer (NSCLC) and SCLC.

Methods: ASCO convened an Expert Panel of medical oncology, thoracic surgery, radiation oncology, pulmonary, radiology, primary care, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000 through 2019. Outcomes of interest included survival, disease-free or recurrence-free survival, and quality of life.

Effectiveness of first-line treatments in metastatic squamous non-small-cell lung cancer.

Background: Commonly used first-line (1L) chemotherapies for patients with advanced squamous-cell lung cancer (scc) include gemcitabine-platinum (gp), nab-paclitaxel-carboplatin (nabpc), and sb-paclitaxel-carboplatin (sbpc) regimens. However, no head-to-head trials have compared those treatments. In the present study, we compared the efficacy of 1L gp, nabpc, and sbpc in patients with scc and in patients with scc who subsequently received second-line (2L) immunotherapy.

A pooled analysis of two phase II trials evaluating metformin plus platinum-based chemotherapy in advanced non-small cell lung cancer.

Background: Despite a wealth of preclinical and observational data, prospective data regarding the use of metformin in lung cancer is extremely limited.

Methods: We pooled individualized data from two prospective trials evaluating metformin plus platinum-based chemotherapy, with or without bevacizumab, in non-diabetic patients with untreated advanced NSCLC. In addition to reporting on clinical efficacy and safety endpoints, we also explored metformin's activity in key molecular cohorts.

Afatinib With Pembrolizumab for Treatment of Patients With Locally Advanced/Metastatic Squamous Cell Carcinoma of the Lung: The LUX-Lung IO/KEYNOTE 497 Study Protocol.

Background: Afatinib is a selective, irreversible ErbB family blocker that has shown survival benefit in lung squamous-cell carcinoma (SCC) patients. Pembrolizumab, a humanized immunoglobulin G4 monoclonal antibody to the programmed cell death 1 (PD-1) receptor, has also shown survival benefit in lung SCC. Concurrent inhibition of the PD-1 and epidermal growth factor receptor (EGFR) pathways represents a rational approach to improve responses and delay the onset of treatment resistance in lung SCC.

Clonal Hematopoiesis: A New Layer in the Liquid Biopsy Story in Lung Cancer.

Cell-free DNA (cfDNA) is a unique biospecimen that contains multiple sources of DNA, including tumor, germline, fetal, and others. Clonal hematopoiesis, a process that leads to expansion of mutations in peripheral blood cells, is an additional source of DNA that adds a layer of complexity when interpreting results. .

Metformin as a repurposed therapy in advanced non-small cell lung cancer (NSCLC): results of a phase II trial.

Background Metformin has been shown to have anti-neoplastic activity in non-small cell lung cancer (NSCLC) in both preclinical and observational studies, however this has never been prospectively evaluated. This single-arm phase II trial, while not fully accrued, is the first known prospective study evaluating the use of metformin with chemotherapy in advanced NSCLC. Methods Patients received carboplatin AUC 5 + pemetrexed 500 mg/m2 IV every 21 days for 4 cycles.
