Is biological immunotherapy effective for advanced lung cancer?

The effect is affirmative. But it also depends on the patient's physical condition. If the patient is already in a tumor cachexia state, he is unconscious, unable to eat independently, or even unable to take care of himself, and needs someone to take care of him at any time, then his own immune mechanism is already very poor. The mechanism of biological immunotherapy requires autologous blood collection, extraction of immune cells and in vitro culture. If the patient's constitution is poor, fewer immune cells will be extracted, and of course, not many immune cells will be cultivated. Just like farming, how can we produce more fruits with fewer seeds, don't you think?
