Cancer patient with unknown blood loss

[luvkenken]

My brother has testicular choriocarcinoma cancer. 3 regimens of chemo, 2 surgeries, bone marrow transplant and head radiation.   Metastasis everywhere including the brain after 2 years.  Highly anemic needing blood transfusions every 2-3 days with fever.  No hemolysis, bone marrow still producing, no internal bleeding.   Doctors cannot find source of infection or the reason for continuous blood loss. Does anyone have any ideas why he keeps losing blood?

Well, see what the results of this RBC scan are and go from there.  

Positive blood cultures?  

What other medications is he taking?

Yes he was seen by both a hematologist and infectious disease dr. His last round of chemo was in in may along with the bone marrow transplant. Then he started oral etoposide chemo drug about two months later but it was stopped after 9 days due to all the blood loss and fever. The etoposide was a mild dose was suppose to be much more tolerable than the other chemo regimens. Just had a rbc nuclear scan yesterday do we will know the results tomorrow. Thank you for responding. Hopefully the rbc scan will find the problem and get fixed.

For starts, has a Hematologist  and an ID (Infectious Disease) Specialist been consulted?  

When was his last round of chemo?  

Has he had a RBC Nuclear scan done?
