Proton therapy currently gains traction as a modality for radiation therapy. In Poland, according to Regulation of Ministry of Health of 6^th of July 2016 (Journal of Laws, item 855), treatment of the following types of tumors are funded by government with this method:

1) Base of the skull and spinal axis tumors in adult: chordoma and chondrosarcoma ICD-10:C41 code (patients after non-radical resections or not amenable to surgery of primary tumor or recurrent), pediatric: soft tissue and bone sarcomas, ICD-10: C41 and C49 code (cases with parameningeal location, base of the skull and parameningeal location).

2) Perinasal sinuses tumors: malignant melanoma, esthesioneroblastoma, adenoid cystic carcinoma, mucoepidermoid carcinoma, undifferentiated carcinoma, codes: ICD-10: C30, C31 (patients after non-radical resections or not amenable to surgery of primary tumor or recurrent).

3) Pediatric tumors requiring cerebroispinal axis irradiations, codes: ICD-10: C-71 (germ cell tumors: medulloblastoma and other PNETs, pineocytoma, Malignant ependymoma with cerebrospinal fluid dissemination, choroid plexus carcinoma).

4) Low grade gliomas (WHO G1 and G2) ICD: C71 (patients who benefit from sparing organs-at-risk in comparison to photon radiotherapy).

Currently, in many institutions clinical trials focused on efficacy of proton therapy for all possible tumor location are being conducted.
