Histologic subtypes were type AB (n = 1), type B (n = 5) and type C (n = 3). Treatment consisted of tumor resection (4 R0, 4 R1, 1 R2) via right anterior thoracotomy, posterolateral thoracotomy, left thoracoscopy, sternotomy and cervicosternotomy, and/or chemotherapy, mainly cyclophosphamide‐doxorubicin‐cisplatin (CAP; n = 5), and/or radiotherapy (n = 4). Two patients with TET type C died. All other patients are alive with a median follow‐up of 4 years (range: 1.5–20). Review of a total of 93 pediatric cases reported in the literature showed statistically significant associations between less favorable histologic subtypes and male gender (<italic>P</italic> = 0.012), advanced Masaoka stage (<italic>P</italic> < 0.001) and quality of resection (<italic>P</italic> < 0.001) respectively.</p> </sec> <sec id="pbc25159-sec-0004" sec-type="section"> <title>Conclusions</title> <p>A review of the literature and our series identified several risk factors to take into account in the therapeutically decision.
