OBJECTIVES: The objective of this study is to summarize the clinical characteristics, treatment, and prognosis of parotid tumors in children and adolescents. METHODS: Fifty-three children and adolescents diagnosed with parotid gland tumors were included. Survival was evaluated using the Kaplan-Meier method. Log-rank test and multivariate analysis were used to analyze the association between clinical factors and recurrence. RESULTS: Of the 53 patients, 30 cases were benign and 23 cases were malignant. All patients underwent surgery. Patients with malignant tumors with high-risk factors received radiotherapy or chemotherapy. The median follow-up time was 61 months. Of these, 1 patient with benign tumor and 5 patients with malignant tumors recurred. Of the patients with malignant tumors, 2 developed distant metastases and 2 died. The 5-year overall survival (OS) and 5-year locoregional recurrence-free survival (LRFS) rates for benign tumors were 100.0% and 92.9%, respectively, whereas the 5-year OS and 5-year LRFS rates for malignant tumors were 94.4% and 72.5%, respectively. The log-rank univariate test showed that tumor size >3.5 cm ( = .056), distant metastasis ( = .056), and stage III and IV ( = .032) were associated with recurrence. However, multivariate analysis did not show the above factors to be independent prognostic factors for LRFS. CONCLUSION: Surgery for benign tumors depends on the location and size. Surgery for malignant parotid tumors depends mainly on the stage, grade, pathological type, and recurrence. Prophylactic lymph node dissection is required for high-grade tumors. Radiotherapy or chemotherapy for children needs more research. Both benign and malignant tumors have high survival rates after active treatment. LEVEL OF EVIDENCE: Level 2.
目的:本研究的目的是总结儿童和青少年腮腺肿瘤的临床特征、治疗方法及预后情况。 方法:纳入53例诊断为腮腺肿瘤的儿童和青少年。采用Kaplan-Meier法评估生存率。采用对数秩检验和多因素分析来分析临床因素与复发之间的关联。 结果:53例患者中,30例为良性,23例为恶性。所有患者均接受了手术治疗。具有高危因素的恶性肿瘤患者接受了放疗或化疗。中位随访时间为61个月。其中,1例良性肿瘤患者和5例恶性肿瘤患者复发。恶性肿瘤患者中,2例发生远处转移,2例死亡。良性肿瘤的5年总生存率(OS)和5年局部区域无复发生存率(LRFS)分别为100.0%和92.9%,而恶性肿瘤的5年OS和5年LRFS分别为94.4%和72.5%。对数秩单因素检验显示,肿瘤大小>3.5 cm(P = 0.056)、远处转移(P = 0.056)以及Ⅲ期和Ⅳ期(P = 0.032)与复发相关。然而,多因素分析未显示上述因素是LRFS的独立预后因素。 结论:良性肿瘤的手术取决于肿瘤的位置和大小。腮腺恶性肿瘤的手术主要取决于分期、分级、病理类型和复发情况。高级别肿瘤需要进行预防性淋巴结清扫。儿童放疗或化疗需要更多研究。积极治疗后,良性和恶性肿瘤的生存率均较高。 证据水平:2级。
