ABSTRACT
BACKGROUND AND AIMS:
Bronchial carcinoids are rare in children and the treatment is based on tumor behavior in adults. The purpose of this study was to determine factors and management strategies associated with long-term survival in the pediatric population using a national cohort.METHODS:
Patients aged ≤20 years with bronchial carcinoid tumors were identified in the 2004-2020 National Cancer Database using ICD-O-3 codes. Tumor characteristics and management were compared among typical (TC) and atypical (AC) histological subtypes using Chi-square and Fisher's exact tests. Kaplan-Meier and univariate Cox proportional hazards analyses were used to assess survival.RESULTS:
Of 273 patients, 251 (92%) had TCs, and 22(8%) had ACs. The median (IQR) age was 18 (16,19) years. Most patients underwent lobectomy or bilobectomy (67%), followed by sublobar resection (17%), no resection or bronchoscopic excision or ablation (8%), and pneumonectomy (7.7%). Margins were negative in 96%. Lymph node (LN) assessment was performed in 216 patients (84%) with a median (IQR) of 7(3,13) LNs, and 50 (23%) had ≥1 positive LN. There was no difference in age, resection, margin status, LN assessment, or positivity between TC and AC (all p > 00.05). Detection of nodal metastasis did not increase beyond the resection of 1-3 LNs (p = 0.72). Ten-year survival was worse for AC than TC (79% (41, 100) vs 98% (95, 100), HR = 6.9 (95% CI 1.2-38.3, p = 0.03). Ten-year survival among those with and without LN assessment was 97% (94, 100) vs 91% (81, 100), HR = 4.0, 95% CI 0.8-19.9, p = 0.09). There were no deaths in those with negative LN while 10-year survival was 89% (72, 100) in those with ≥1 positive LN.CONCLUSION:
Among children with bronchial carcinoids, survival is excellent with TC or negative LN. Atypical histology and positive LN have poor survival and should prompt close monitoring. These risk factors may be missed in the absence of surgical resection and lymph node sampling. LEVEL OF EVIDENCE III. TYPE OF STUDY Retrospective Study.Key words
