[|Human|] my father has been diagnosed with adenocarcinoma + malt lymphoma at CMC,Vellore where GIST was been operated by opting subtotal gastrectomy.I have come to know about your institute from a friend what can be done in this respect as doctors have recommended for keymotherapy
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Yes, post-operative chemotherapy is advisable in GIST (gastrointestinal stromal tumor). It is to treat distal metastasis. GIST is known to cause local site recurrence and distal metastasis like lungs, liver, kidney, bones etc. So chemotherapy is needed to prevent metastases at these sites. It also prevents local site recurrence. So it is advisable to give chemotherapy in his case. Hope I have solved your query. Wishing good health to your father. Thanks.
