Other treatment modalities for LM have been studied but none of them still has proved to be efficient enough. Recently, photodynamic treatment (PDT) has been suggested as a promising novel treatment method for LM. [clinicaltrials.gov]

Non-surgical treatment options include the following. Radiotherapy (RT) RT has been used for decades for the treatment of MM, including LM, although nowadays it is not considered as the primary treatment option. [spandidos-publications.com]
