Consultation on Stomach Cancer (N. H.

I am 60 years old. I have an ulcer and cancer at Esophagus / Stomach (NHL) detected in December, 2011. Bone Marrow test was normal. Had eight Chemos Plain CHOP till July, 2012. No surgery was done. No Radiation was given. H’pylori infection was treated with Hpylori Kits for long period till Reports were normal. Periodically, I have done Check up including Gastroscopy, Biopsy, Blood Tests (BU, SC, KFT, LFT, LDH, ESR, Lipid Profile, HBA1c). Recent tests are normal within limit. Last PET Scan done in Dec., 2014 was normal. Last biopsy done in October, 2015. Histopath Report indicates CD3 (ClonePS1)-Positive, CD-20 Positive. CK (Clone AE1+AE3) Positive, MiB1 (Clone)- Positive. It shows inflammation. I do not have any symptoms of cancer, at present. I have constant weight (70 kgs). My appetite and digestion is normal. Wish to know whether Cancer is likely to be RELAPSED. I am still required to follow up and do Gastroscopy, PET scan, Blood Tests etc. again. Kindly advise.
