For patients with advanced lung cancer, the main thing is to improve their quality of life. In clinical practice, patients are given a staging of their quality of life, called PS score. If you use the Carlsbad score, a score of 60 means that the patient can take care of himself/herself, can clean and clean his/her home, can put on clothes and fold the blanket, and can go to the toilet. When the score is above 60, if the patient is still able to undergo chemotherapy, the patient can be given chemotherapy treatment, which can slow down the progression of the tumor. Of course patients who check genetic testing can take targeted drugs, no matter how poor their physique is, they can take oral targeted drugs to inhibit their tumor growth. For a patient, if the PS score is below 60, the treatment is generally called best supportive care, that is, to make the patient’s quality of life higher, such as taking painkillers for pain on the body and trying to make the patient eat if he does not want to eat, so as to achieve the purpose of improving the patient’s quality of life. Therefore, in clinical practice, patients with advanced lung cancer are not denied all at once, and a suitable treatment plan should be chosen according to the patient’s condition, in addition to psychological guidance. If the patient is very comfortable, it is believed that his or her quality of life, including life expectancy, can still be extended.
