What are the effects of gamma knife radiation to the cavernous sinus cavity & pituitary gland due to an invasive atch secreting tumor?

What are the effects of gamma knife radiation to the cavernous sinus cavity & pituitary gland due to an invasive atch secreting tumor?

Possible scarring: Pituitary adenomas are nearly always benign tumors, but can be quite locally destructive or infiltrative, making them difficult to remove from all of the nooks and crannies of the region. Radiation provides a way of controlling the growth. Cavernous sinus isn't usually affected, although rare thrombosis can be seen. ...Read more

Can facial squamous cell cancer lead to brain cancer even if the initial surgery was successful?

Can facial squamous cell cancer lead to brain cancer even if the initial surgery was successful?

Not usually.: If a skin cancer is deeply invasive through the skull, it can sometime grow into the brain. Sometimes a tumor can crawl along the nerves back into the brain, but this is more common with tumors like adenoid cystic carcinoma.

Is radiation for a squameous cell cancer tumor behind eye on optic nerve next to brain safe or could it cause necrosis of brain. Do I need proton?

Is radiation for a squameous cell cancer tumor behind eye on optic nerve
 next to brain safe or could it cause necrosis of brain. Do I need proton?

Palliative: Retrobulbar optic nerve involvement with metastatic tumor rare. Squamous malignancies are very few in that area. Chemo and RT given have mostly been palliative. Gamma knife therapy might be better than trying proton beam. With RT and chemo results in general have not been that encouraging. ...Read more

With inoperable non-small cell lung cancer, if there's a targetable genetic mutation (EGFR etc) can it be treated at stage 3A? Alongside chemo/radio?

With inoperable non-small cell lung cancer, if there's a targetable genetic mutation (EGFR etc) can it be treated at stage 3A? Alongside chemo/radio?

Yes: EGFR mutations (exon 19 or 21) in lung cancer are more common in non-smokers, Asians, and women. Upfront use of an oral tyrosine kinase inhibitor (TKI) results in better progression-free survival than chemotherapy when these mutations are present, although overall survival is not different. Discuss options with your oncologist. ...Read more

Hi, tell me a way to cure a malignant melanoma that has metastesised in two axillary lymph nodes? Chemo, radiation and surgery is not an option.

Hi, tell me a way to cure a malignant melanoma that has metastesised in two axillary lymph nodes? Chemo, radiation and surgery is not an option.

Limited options: Ask yourself why these are not options, and discuss with a surgical oncologist. Patients do very well after an axillary dissection and return to normal activities with the arm. You may be relying on incorrect information in making that decision. The most feared side effect, lymphedema, will likely occur anyway secondary to the cancer under the arm. Surgery alone may be curative. ...Read more

Can a cyberknife be used to treat limited small cell lung cancer?

Can a cyberknife be used to treat limited small cell lung cancer?

There is no: Cogent role for cyberknife in sclc and it would be a misuse of that expensive technology. Chemotherapy is the standard for limited or extensive disease, thoracic radiotherapy with linac is standard in disease confined to chest. All those warrant preventitive radiotherapy to the brain if the chest responds. ...Read more

Can multiple myloma be cured 100%? What will be the cost of stem transplant which I heard is the best option to fight this cancer?

Cure in vocabulary: Traditionally we have thought of multiple myeloma as incurable. However the "c word" cure is now in the vocabulary. At ash 2009 dr. Barlogie talked about cure. An mdacc study from 1987-1997 (=old data) showed a 10yr os "cure fraction" of 2% (ash 2009 #3864). The majority of mm pts are not cured, but it is now possible in a small fraction of pts and may increase in the future. ...Read more
