You are not clear about the platelet count
prior and after Inj. Eptoin. Eptoin has no role in reducing the platelet count suddenly. Cancer and it's treatment (in what ever form) will reduce the cell counts, because of bone marrow
Your mother has crossed the stage of surgery or not fit for surgery - that is why Chemotherapy
is advised. She is already a known patient of seizure disorder
. She was on tab. Eptoin which was stopped 20 yrs back and assumed that after 20 yrs she has developed only one episode of seizure now.
one of the many causes for the current seizure is Secondary brain involvement. So no harm in continuing eptoin. The edema and increase in size of abdomen, feeling sleepy, fluctuating BP & seizurs are due to Primary lesion and Secondary metastasis
. You can understand the present condition of your mother associated with low platelet count (platelets play a major role in clot formation to arrest bleeding) . We will hope for the best.
