Former Senator Facing Marrow Transplant

Former U.S. Sen. Paul Tsongas was admitted Thursday to the Dana-Farber Cancer Institute for treatment of an infection caused by a bone marrow disorder related to his bouts with lymphoma.

Doctors anticipate Tsongas will undergo a bone marrow transplant in the “relatively near future,” said Dr. David G. Nathan, Dana-Farber’s president.

Tsongas’ condition, called myelodysplasia, is not uncommon in people who have recovered from lymphoma, cancer of the lymph glands, Nathan said.

Tsongas, 55, has been cancer-free since November 1992.
