My husband is to begin radiotherapy (IMRT) soon to his neck and lower jaw, but I am very worried about the dosage. According to the radiotherapy oncologist, he wants to give him 2 Gy daily, 5 times a week, for 6 weeks. Based on this information, he would be getting 60 Gys in total to the same area . Does this sound right? I've been searching previous posts to try to gauge whether this is standard, but compared to the previous posts I have found which mention radiotherapy dosages, 60 Gys is way too high. I know I should do more research myself, but have been hit by another whammy as we have not been able to schedule the brain MRI which the medical oncologist ordered due to the insurance company saying it is not covered. The oncologist says it is, so we believe it is just the insurance company being difficult.
To recap on my husband's resected tumor via parotidectomy and CLND:
Nodular type, Clarke level of V, Breslow thickness of 17mm, ulceration present, no regression identified, lymphovascular invasion not identified, perineural invasion not identified, mitotic rate of 19 per 10 HPF, micro satellite lesions not identified, closest margin of 14mm (invasive), deep margin of 2.5mm (invasive), 2 involved lymph nodes out of 43 retrieved (one of which is involved due to direct extension), Level II-IV lymph nodes from separate right neck dissection are negative for metastatic melanoma, pathological stage: pT4b N1
Any sharing of radiotherapy experience would be so greatly appreciated.
Thank you once again for all your support, and take very good care of yourselves.
