Abstract

Background: The management of laryngeal cancer involves balancing curative treatment with preserving essential functions. This study aimed to evaluate the clinical outcomes of helical tomotherapy, an advanced form of radiation therapy, as a primary treatment modality for laryngeal squamous cell carcinoma (LSCC).

Methods: A retrospective analysis of data obtained from a tertiary referral center was performed to assess treatment response rates, survival outcomes, disease control, and treatment-related adverse events.

Results: The study included 45 patients with LSCC treated with helical tomotherapy between May 2015 and September 2022. The 5-year overall survival (OS) rate and disease-free survival (DFS) rate were 89.2% and 71.1%, respectively. Local control and laryngeal preservation rates at 5 years were 79.7% and 84.7%, respectively. Subgroup analysis revealed higher DFS rates in early-stage patients (84.2%) compared to advanced-stage patients (58.9%).

Conclusions: The results indicate that helical tomotherapy offers effective tumor control and potential for laryngeal preservation in LSCC. Further prospective studies and longer follow-up are needed to validate these findings and optimize treatment strategies for LSCC patients.

利用螺旋断层放射治疗喉鳞状细胞癌的临床疗效：一家三级转诊中心的回顾性分析。

背景：喉癌的治疗需要在根治性治疗和保留基本功能之间取得平衡。本研究旨在评估作为喉鳞状细胞癌（LSCC）主要治疗方式的螺旋断层放疗的临床效果：方法：对一家三级转诊中心获得的数据进行回顾性分析，评估治疗反应率、生存结果、疾病控制和治疗相关不良事件：研究纳入了2015年5月至2022年9月期间接受螺旋断层治疗的45例LSCC患者。5年总生存率（OS）和无病生存率（DFS）分别为89.2%和71.1%。5年的局部控制率和喉保留率分别为79.7%和84.7%。亚组分析显示，早期患者的 DFS 率（84.2%）高于晚期患者（58.9%）：结论：研究结果表明，螺旋断层扫描疗法能有效控制肿瘤，并有可能保留LSCC患者的喉部。需要进一步的前瞻性研究和更长时间的随访来验证这些发现，并优化LSCC患者的治疗策略。

期刊介绍： World Journal of Oncology, bimonthly, publishes original contributions describing basic research and clinical investigation of cancer, on the cellular, molecular, prevention, diagnosis, therapy and prognosis aspects. The submissions can be basic research or clinical investigation oriented. This journal welcomes those submissions focused on the clinical trials of new treatment modalities for cancer, and those submissions focused on molecular or cellular research of the oncology pathogenesis. Case reports submitted for consideration of publication should explore either a novel genomic event/description or a new safety signal from an oncolytic agent. The areas of interested manuscripts are these disciplines: tumor immunology and immunotherapy; cancer molecular pharmacology and chemotherapy; drug sensitivity and resistance; cancer epidemiology; clinical trials; cancer pathology; radiobiology and radiation oncology; solid tumor oncology; hematological malignancies; surgical oncology; pediatric oncology; molecular oncology and cancer genes; gene therapy; cancer endocrinology; cancer metastasis; prevention and diagnosis of cancer; other cancer related subjects. The types of manuscripts accepted are original article, review, editorial, short communication, case report, letter to the editor, book review.
