Many younger patients with stomach cancer have a distinct disease, Mayo research discovers

(Mayo Clinic) Many people under 60 who develop stomach cancer have a 'genetically and clinically distinct' disease, new Mayo Clinic research has discovered. Compared to stomach cancer in older adults, this new, early onset form often grows and spreads more quickly, has a worse prognosis, and is more resistant to traditional chemotherapy treatments, the study finds. The research was published recently in the journal Surgery.
