Gregg Howard Goldstein, 39, an international economics consultant and former Capitol Hill staff member, died of a brain tumor Nov. 26 at the M.D. Anderson Hospital in Houston.

He served on the staff of Rep. Michael Allen Andrews (D-Tex.) from 1983 to 1985, then joined the Washington staff of the Bank of Japan. An authority on energy matters, he did economic consulting before returning to Texas in 1989.

Mr. Goldstein was a foreign trade specialist with the Texas Agriculture Department in 1990 when he was diagnosed with an astrocytoma, a type of brain tumor.

Although he recovered from his initial bout with the disease, he was unable to find work. The Post, in a 1996 story by Abigail Trafford, told of the difficulties Mr. Goldstein, and others like him, faced in the job market. After the story appeared, Mr. Goldstein was again found to have a brain tumor, and he never returned to a full-time job in his profession.

He became a member of the board of directors of M.D. Anderson Hospital's Anderson Network. The network matched patients who had just been diagnosed with serious ailments with patients who had been cured of the same diseases or who had been fighting them for some time.

In the last years of his life, Mr. Goldstein divided his time between his home in Austin and Houston, where he received treatment and did volunteer work with the Anderson Network.

Mr. Goldstein, who was born in Houston, was a graduate of the University of Texas. He received a master's degree in international economics from Johns Hopkins University's School of Advanced International Studies and was its 1988 student commencement speaker.

He had been active in Young Judea. In 1978 and 1979, he lived in Israel. He was fluent in Spanish and Hebrew.

Survivors include his father and stepmother, Leonard A. and Helen W. Goldstein of Houston; his mother, Janice B. Gaines of Stamford, Conn.; and a brother.
