welcome to our small world.
1. Gemcitabine and Cisplatin are the current standard of choice of Tx for cholangiocarcinoma(CCA). there are still many other regimens to choose from if this one is not suitable for your mom in the future.
Gemcitabine is easy to take,minimum side effect like low platelets count is one of the the most stand out side effect. Nausea and vomiting,loss of hair,fatigue,body ache,nephrotoxicity(kidney);hypomagnseium and hypopotassium are side effects of cisplatin. Nephrotoxity is accumulative and therefore ,depending on the health of the patient,after certain # of cycle(ie: 6 cycles) ;review of the regimen may be a good way to protect esp. the kidney if the side effects cannot be tolerated well.
To start the chemotherapy each time overnite is a good idea and I don't know why we cannot do this here in the States. It is less anxiety to the patient and they can sleep thru some of the unwanted side effects of the chemotherapy.
2. 63 years young and otherwise healthy individual after left liver resection, (even had a lympth node positive involvement )has a good chance to live long enough for the next new thing to come in radiation oncology or/and medical oncology to extend our lives with much less side effects and enjoy God's mercy for those who suffer. I do not see a "magical pill "will be discovered in the near future like penicillin for infection that provide a "CARE" for us.
3. Continue to pursuit other options such as radiation treatment ;read and learn about it and other development of treating this CCA is the way to handle this disease. I am a CCA patient for 35months,like your mother,I had the left lobe completely resected;on gemcitabine for 14 months;off the chemotherapy for 6 months,CCA came back;RFA and chemoembolization; then re-resection again.Now is only on Xeloda(pro-drug of 5FU);and the rest is up to God's mercy.
what I am trying to say is this; CCA is a long and winding road to navigate ; it require courage,knowledge and patience; it is not easy but it can buy time for your mother.
