Hi Drew, I am sorry to hear about your brother in law. The following link might be worth reading on his behalf regarding the combined use of melatonin and vitamin D alongside chemo and radiotherapy as both offer anticancer effects of their in multiple forms of cancer including osteosarcoma and offer some protective effects against some of the known side effects of both chemo and radiotherapy. :
https://pmc.ncbi.nlm.nih.gov/articles/PMC11575929/
Here is a relevant quote from the research paper :
' As regards the central discussion of the present review, VitD and melatonin supplementation exhibit efficacy against several types of cancer. Clinical trials on this combination are still limited but are valuable in improving the quality of life of cancer patients. Specifically, human studies involving osteosarcoma, as well as lip, oral cavity, pharynx, breast, head, neck, brain and lung cancers are examples of these improvements. VitD and melatonin also have radioprotective potential, which could improve the effectiveness of radiotherapy and protect patients from its side-effects. The use of synthetic radioprotective compounds is restricted due to the occurrence of undesirable health consequences, particularly when higher doses are required for maximum radioprotection. Considering the prevalent deficiencies of melatonin and VitD in modern societies, supplementing with both substances would be crucial, given that such deficiencies may exacerbate the adverse effects of radiotherapy (e.g., ionizing radiation) and chemotherapy. In this sense, further studies are warranted to determine optimal doses when these agents are used in combination. '
' In addition to reducing the growth of cancer cells and improving the life quality of patients, this combination may improve sleep quality providing an indirect benefit on the cancer mediated by the connections between sleep and the immune system (229).'
His doctor will have to determine dosing that will be compatible with the chemotherapy treatment.

Drew, Dr William Coley was curing such cancers already a 100 years ago. It cured my lymphoma. Look up Coley's Toxins.
