The complete response to targeted drugs without surgery or radiotherapy: a case of pituitary metastasis from renal cell carcinoma

Pituitary gland metastasis was seen in elderly patients and the incidence of pituitary metastasis is 1% to 4% in all cancer patients. Renal cell carcinoma is a primary malignancy in only 2.6% of pituitary metastases. We reported a 50-year-old man with pituitary metastasis from renal cell carcinoma that had signs of diabetes insipidus. He had multiple lesions in both lungs and in bone scan was involved L12 and L1 vertebrates. He was treated with combination bevacizumab 600 mg per month and sunitinib 50 mg per day for four weeks with two weeks rest for 6 months.
Treatment with targeted drugs without surgery of pituitary or radiotherapy improved metastatic renal cell carcinoma in patient.
