Unfortunately, there is a law of diminishing returns with investigations in
this situation. If a history and physical and some basic investigations fail
to find the primary site, it is unlikely to be found.
Unfortunately, it is also true that for most patients with metastatic
disease from unknown primary sites, finding the primary will not make the
effectiveness of the treatment any better. The only adenocarcinomas in which
discovering the primary site may make a difference to treatment are
prostate, {*filter*}, and a germ cell tumour masquerading as an adeno. They will
certainly have done the investigations to exclude these.

Platinum chemo is a very common approach in these circumstances.
Unfortunately, there is no evidence that it improves survival. The real
issue is whether it will improve quality of life, not quantity. This largely
depends on your father's symptoms.
