So sorry to hear about your father.
I don't know about side effects of those treatments. However, the rapid body weight loss, sometimes called "wasting", in cancer patients seems to far exceed what could be lost by simple lack of nutrition. If you simply stop eating it's hard to lose 10 pounds a week. That's on the order of 36000 calories deficit, or over 5000 per day. A resting person's body only burns typically 1500-1800 a day, so something else seems to be happening. The medical term I've heard is cachexia, essentially an unstoppable rapid weight loss, seen in end-stage cancers.
I watched my brother in law become a living skeleton by the end of his pancreatic cancer, from relatively normal to unsurvivable in about 3 months. Perhaps the high metabolic rate of cancer itself consumes all those calories. I don't know, but it's dramatic, and it just seems far too fast for simple malnutrition to explain.
