Several factors are associated with a good prognosis of stomach lymphoma. The main factors include if the patient is younger than 65, progression of the disease, good surgical margins after resection and total remission after primary cancer treatment, as explained by Virtual Medical Centre.
The prognosis isn't as positive if a patient with stomach lymphoma has H. pylori disease. The presence of the two diseases results in chromosomal changes that hinder treatment response to antibiotics. However, tissue obtained from biopsy can be used to test these chromosomal changes. With low-grade disease, patients have as high as a 91 percent five-year survival rate, but the survival rate decreases to 56 percent in patients with high-grade disease, according to Virtual Medical Centre.
