My dad was previously treated for Oral Cancer (Left Tongue Glossectomy, Left SND, CCRT) in early 2009 and had slowly recovered but everything came crashing down when he was diagnosed for recurrent nodal metastasis on his right neck.

He was put on pallative DCF chemo for 3 cycles to reduce tumor size prior to surgery, which did not happen. He just had RND and Flap. Biopsy reports says PNI, ECE and soft-tissues from Carotid artery and prevertebral are positive.

He is up for reirradiation and I am feeling terrible with the thought that he has to go through all that again!

Is there any means to preserve his salivary secretion (whatever he has got now after recovery)?

Has anyone been on Salagen (pilocarpine)? Not sure if we get that in India but will try to source, if it is effective and RO is OK with it.
