Abstract
OBJECTIVES Selective radiotherapy and concomitant intra-arterial cisplatin infusion (m-RADPLAT) with a lower cisplatin dosage have been performed for organ and function preservation in patients with locally advanced squamous cell carcinoma of the larynx (SCC-L), and results showing a lower rate of adverse events have been reported. This study evaluated the treatment outcomes of patients with T3N0 glottic SCC-L with or without vocal fold fixation (VFF) who were treated with m-RADPLAT. METHODS We retrospectively reviewed the data of 33 patients with T3N0 SCC-L who received m-RADPLAT. RESULTS The vocal fold in patients with VFF 3 months after completing m-RADPLAT resumed normal movement in 15 patients (83%) and persisted fixation in 3 (17%). The 3-year local control, laryngeal cancer-specific survival, and overall survival rates of patients with or without VFF were 88.9% and 86.7%, 94.1% and 93.3%, and 88.9% and 86.7%, respectively. Additionally, the 3-year freedom from laryngectomy, laryngectomy-free survival, and laryngo-esophageal dysfunction-free survival rates of patients with or without VFF were 94.4% and 86.7%, 88.9% and 73.3%, and 83.3% and 73.3%, respectively. Grade 3 or higher toxicities were observed in all patients: leukopenia in 4 patients (12%), neutropenia in 5 (15%), anemia in 2 (6%), thrombocytopenia in 3 (9%), and mucositis in 2 (6%). CONCLUSIONS This study demonstrated that m-RADPLAT yielded VFF improvement and a favorable survival while maintaining laryngeal function not only in patients with T3N0 glottic SCC-L without VFF but also in patients with VFF.

Yu B, Wang J. Lipidomics Identified Lyso-Phosphatidylcholine and Phosphatidylethanolamine as Potential Biomarkers for Diagnosis of Laryngeal Cancer. Front Oncol 2021; 11:646779. [PMID: 34262857 PMCID: PMC8273650 DOI: 10.3389/fonc.2021.646779] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Accepted: 06/11/2021] [Indexed: 01/16/2023] Open
Abstract
Background Laryngeal cancer (LaC) remains one of the most common tumors of the respiratory tract with higher incidence in men than in women. The larynx is a small but vital organ on the neck. The dysfunction of the larynx can cause serious health problems such as hoarseness, respiratory distress, and dysphonia. Many lipids (e.g. phospholipid, cholesterol, fatty acid) have been recognized as a crucial role in tumorigenesis. However, the lipid biomarkers are lacking and the lipid molecular pathogenesis of LaC is still unclear. Methods This study aims to identify new LaC-related lipid biomarkers used for the diagnosis or early diagnosis of LaC and to uncover their molecular characteristics. Thus, we conducted serum and tissue nontargeted lipidomics study from LaC patients (n = 29) and normal controls (NC) (n = 36) via ultra-high performance liquid chromatography (UHPLC) coupled with high resolution mass spectrometry (HRMS). Multivariate and univariate statistics analyses were used to discriminate LaC patients from NC. Results As expected, a lipid panel including LPC (16:0) and PE (18:0p_20:4) was defined to distinguish the LaC patients from healthy individuals with very high diagnosis performance (area under the curve (AUC) value = 1.000, sensitivity value = 1.000, and specificity value = 1.000). In addition, the levels of Cer, CerG1, SM, PC, PC-O, PE, PI, PS, and ChE in the LaC group significantly increased as compared with the NC group. However, the levels of LPC, LPC-O, LPE, LPE-p, and DG in the LaC group significantly deceased when the one was compared with the NC group. Among significantly changed lipid species, lysophospholipids containing a palmitoyl chain or an arachidonic acid acyl chain remarkably decreased and phospholipids including a palmitoyl chain or an arachidonic acid acyl chain increased in the LaC patients. Conclusion Our results not only indicate that lipidomics is powerful tool to explore abnormal lipid metabolism for the laC, but suggest that lysophospholipids and phospholipids may serve as potential biomarkers for diagnosis of LaC.
