Alternative and/or complementary therapies available for pituitary
tumor. Already found endoscopic surgery technique; seeking
non-invasive techniques. ($2.50)

Hi there -

I (and I suspect other researchers) have not been able to find
information on complementary medicine approaches to pituitary tumors. 
Sorry!  I did find a passing reference in a Chinese medical journal
about the use of acupuncture for treatment, but have not been able to
locate the article.

This page from the National Cancer Institute gives an overview of
standard treatments for different types of pituitary tumors:
http://www.cancer.gov/cancertopics/pdq/treatment/pituitary/Patient/page1

There are a number of drugs under consideration for treatment.  Here
is a list of currently recruiting clinical trials (from
Clinicaltrials.gov):

I hope these links help you - I found them on the MedlinePlus topics
page for Pituitary Disorders:
