Introduction: Squamous cell carcinoma is the most common laryngeal neoplasm and accounts for approximately 95% of all malignant neoplams of the larynx. However, various benign and malignant tumors and inflammatory diseases may affect the larynx.

Objective: The purpose of this study is to analyze the clinical and imaging findings of non-squamous cell neoplasms and inflammatory diseases of the larynx.

Methods: This retrospective study was conducted in 18 patients who were diagnosed with non-squamous cell carcinoma lesions of larynx at our institution between 2007-2017. Clinical symptoms, examination findings, imaging characteristics, histopathologic diagnosis and treatment modalities were analyzed.

Results: There were 9 malignant lesions (2 chondrosarcoma, 1 neuroendocrine tumor-atipical carcinoid, 1 Natural Killer/T-cell lymphoma, 1 diffuse large B-cell lymphoma, 3 plasmocytoma-multiple myeloma involvement, 1 adenocarcinoma metastasis), 3 benign neoplasms (chondroma, paraganglioma, lipoma), 2 tumor-like lesions (Brown tumor and inflammatory myofibroblastic tumor), 3 inflammatory lesions (Wegener granulomatosis, Behçet's disease and tuberculosis involvements), and 1 vascular malformation. The most common presenting symptom was hoarseness (66.6%). Paraganglioma was seen as hypervascular lesion on computed tomography and magnetic resonance imaging and showed intense tracer uptake on 68Gallium-DOTA-peptide PET/CT. Chondroid matrix calcifications were detected in chondroma and chondrosarcoma-grade 1. In patients with vascular malformation and lipoma, the typical imaging findings made it possible to diagnose.

Conclusion: Imaging studies may provide clues for diagnosis of non-squamous cell laryngeal lesions. Clinical and imaging findings and previous clinical history should be evaluated together in clinical management of laryngeal lesions.

Purpose: We aimed to elucidate the efficacy of conventional cisplatin-based adjuvant chemotherapy for patients with lung cancers harboring epidermal growth factor receptor (EGFR) mutation.

Methods: This retrospective cohort study included 110 patients (EGFR mutation group: n = 51; EGFR wild-type group: n = 59) receiving cisplatin-based adjuvant chemotherapy following complete resection of non-small-cell non-squamous-cell lung cancer (2010-2021). Clinicopathological characteristics, recurrence-free survival (RFS), and overall survival (OS) were investigated.

Non-small-cell lung cancer (NSCLC) is the poster child of personalized medicine. With increased knowledge about biomarkers and the consequent improvement in survival rates, NSCLC has changed from being a therapeutic nihilistic disease to that characterized by therapeutic enthusiasm. The routine biomarkers tested in NSCLC are EGFR, ALK, and ROS1.

Background: The efficacy and safety of sotorasib plus platinum-doublet chemotherapy in KRAS G12C-mutated non-squamous non-small cell lung cancer (non-Sq NSCLC) were previously reported with limited follow-up period.

Method: SCARLET was a single-arm phase II study of chemotherapy-naïve patients with KRAS G12C-mutated non-Sq NSCLC. Participants received sotorasib 960 mg daily plus four cycles of carboplatin (area under the curve, 5)/pemetrexed 500 mg/m, followed by sotorasib/pemetrexed until disease progression.

Background: To evaluate the real-world surgical and pathological outcomes following neoadjuvant nivolumab in combination with chemotherapy in a multicentre national cohort of patients.

Methods: Retrospective analysis on consecutive patients treated in three tertiary referral hospitals in UK with neoadjuvant chemotherapy and immunotherapy (nivolumab) for stage II-IIIB nonsmall cell lung cancer (March 2023-May 2024). Surgical and pathological outcomes were assessed.

EGFR and ALK are key driver mutations in non-small cell lung cancer (NSCLC). Tyrosine kinase inhibitors are recommended as the first-line treatment for advanced NSCLC with driving oncogenes because they have fewer side effects and provide better disease control than chemotherapy. The present retrospective analysis aimed to investigate how altered driver genes impact cancer outcomes and clinical presentation.
