Answer 2

you could use replace and like
select replace(colname, 'Anti', '"<HIDE> Anti-</HIDE> )
from table where colname like '%Anti%'
and colname not like 'Monoclonal Anti%';
of for a combined situation you can use a case when for lead replace
select case when colname like '%Monoclonal Anti%'
then replace(colname, 'Monoclonal Anti', '"<HIDE> Monoclonal Anti-</HIDE> )
when colname like '%Anti%'
then replace(colname, 'Anti', '"<HIDE> Anti-</HIDE> )
else colname
end
from table where colname like '%Anti%';
