My father,65, was diagnosed in October 2015 of moderately differentiated squamous carcinoma of right upper gingiva , right upper gingivobuccal sulcus. The underlying maxillary bone was involved by tumour. The affected area was surgically removed and local RT was given for 6 weeks. Two weeks ago, PET scan results showed clear head and neck but distinct mets in both lungs - lesion measuring 2.2cm x 1.6cm in right lung lower lobe along the major fissure and another smaller lesion in left lung.

He is diabetic but in good health and has not shown any symptoms of spread to lungs (no breathlessness etc.).

MO is suggesting Metronomic Chemo with Methotrexate and Celecoxib as palliative treatment. MO said no to Cetuximab because "there is only one study which supports its use". He also refused RFA and RT of lungs, "because the lesion is in centre of lung and it is not feasible". Are there any other options? We feel the suggested treatment might be too mild, feels like giving up even before trying.

Also, is resection really not an option in his case? Should we seek another opinion. Appreciate any help!
