Clinical and histopathological features of immune checkpoint inhibitor-induced lung toxicity.

A new era in cancer therapy emerged with the arrival of immune-checkpoint inhibitors (ICIs), followed by a new cadre of immune-related adverse events that affect up to 40% of patients. Literature on the pathological features associated with these events is still limited. Therefore, to expand our knowledge of the histopathologic spectrum of pulmonary changes, we conducted a case study series analysis on 16 non-neoplastic lung samples collected during or after ICI therapy.

Case report: Using DNA short tandem repeats to confirm nongestational origin of pulmonary choriocarcinoma.

Gestational trophoblastic neoplasias (GTN) are malignant neoplasms that occur in pregnant or recently pregnant women. Choriocarcinoma (CCA) is a highly aggressive and rare GTN, and cases outside the female genital tract are commonly seen as secondary manifestations of gynecologic disease. In this paper, we describe the case of a 40 years-old female patient with a primary pulmonary CCA who was surgically treated and for whom the confirmation of the primary origin of the tumor was possible using a DNA short tandem repeat genotyping.

The Meaning of Lymphadenopathies During Adjuvant Durvalumab After Chemoradiotherapy for Lung Cancer: Thinking Beyond Disease Progression.

Immune-checkpoint inhibitors (ICIs) have become the mainstay of treatment for many malignancies. With this new strategy, relevant immune-related adverse events (irAEs) have been reported, some of which can be mistaken for disease progression. To better illustrate the current challenges in diagnosing and managing a patient under adjuvant ICI treatment, we present the case of a 67-year-old female patient with stage IIIB unresectable, epidermal growth factor receptor (EGFR)-mutated, non-small-cell lung cancer who was initially treated with chemoradiotherapy, followed by immunotherapy with durvalumab.

Detection and quantification of T790M mutation in liquid biopsies by droplet digital PCR.

Background: Liquid biopsy allows the identification of targetable cancer mutations in a minimally invasive manner. In patients with advanced non-small cell lung cancer (NSCLC), droplet digital PCR (ddPCR) is increasingly used to genotype the epidermal growth factor receptor () gene in circulating cell-free DNA (cfDNA). However, the sensitivity of this method is still under debate.
