'pancreas-associated' originates from Modern English, specifically the compound of 'pancreas' and 'associated', where 'pancreas' ultimately comes from Greek 'pankreas' and 'associated' comes from Latin 'associare'.

'pancreas' entered English via Latin/Medieval Latin from Greek 'pankreas' (παγκρέας); 'associated' derives from Latin 'associare' > Late Latin and Old French forms and then Middle English 'associate', together forming the modern compound 'pancreas-associated'.

Initially, 'pancreas' referred to the anatomical gland (from Greek meaning roughly 'all flesh') and 'associate' meant 'to join with'; over time the compound came to mean 'having a connection with the pancreas' in medical usage.
