Abstract:
Pituitary apoplexy often occurs in patients with previously undiagnosed pituitary adenomas and no predisposing factors. Among patients with precipitating events, there are very few cases of pituitary apoplexy occurring in the setting of systemic chemotherapy treatment. A 31-year-old man with newly diagnosed metastatic testicular cancer developed headaches, nausea, and a right-sided visual field deficit one week after initiation of bleomycin, etoposide, and cisplatin chemotherapy. Computed tomography and magnetic resonance imaging revealed hemorrhage within a pituitary macroadenoma consistent with pituitary apoplexy, and he underwent urgent transnasal resection. We also review the four prior cases of pituitary apoplexy temporally associated with the administration of systemic chemotherapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Combination Therapies and Personalized Medicine
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
