Answer

For thymic NETs, NCCN recommendations include the following [7] :

  • Localized disease: Surgical resection

  • Locoregional disease: Reresection; if resection is incomplete, follow with radiation therapy and/or chemotherapy

The NANETS guidelines include the following additional recommendations for thymic NETs [14] :

  • Locoregional disease: Surgical resection including mediastinal lymphadenectomy

  • Metastatic or unresectable disease: Options include radiation therapy, everolimus, interferon alpha, or temozolomide

The ESMO guidelines note that a protracted follow-up should always be performed after surgical resection becuse of the high rates of recurrence. For metastatic disease, although the available chemotherapy regimens have not demonstrated good effects, cisplatinum-based regimens have been of value and temozolomide-based treatment gives some benefit.
