From the methods of the anticancer therapies operation can be eligible by itself in the first group but in the second group should form only the part of the multimodal treatment. Radiotherapy plays a role only in the treatment of the small and large cell tumors and during the treatment of these tumors the administration of the cytostatic drugs is also essential (mainly platina derivates). Somatostatin analogs, immune checkpoint inhibitors could be beneficial in special cases and some tumor agnostic treatment can be useful as well.
