Patient: Cough, especially severe at night. The doctor saw the CT scan and electronic bronchoscopy report and said it was lung cancer. The pathological analysis after the electronic bronchoscopy said no cancer cells were found. The thoracic surgeon did not agree to hospitalization and said that in order to operate, chemotherapy must be given first and then see if it is possible. The oncologist suggested that he should go home to recuperate and take some Chinese medicine. Is surgery still possible in my dad’s case, and is there any other way if surgery is not possible. We are more than 14 hours away from Shanghai by train and my dad is weak, so I would like to ask you online about the possibility of surgery before I see if I should come to Shanghai for treatment. Doctor: Whether lung cancer can be operated depends on the following factors: whether the cardiopulmonary function can tolerate surgery; whether there are metastases from organs outside the chest cavity; whether there are metastases from other parts of the chest cavity besides the primary focus, such as pleural metastases and mediastinal lymph node metastases. Lung cancer that can be operated includes stage I-IIIa lung cancer, among which stage IIIa lung cancer with multiple metastases in mediastinal lymph nodes can be considered for surgery after chemotherapy or lymph nodes have shrunk significantly. The five-year survival rate of lung cancer is 70% for stage I, 40% for stage II and 20% for stage III. The average natural survival time for inoperable patients is 8 months, but chemotherapy can extend it to 10-11 months, and the one-year survival rate is about 40%. The latest treatment including targeted therapy can improve the quality of survival and prolong the survival period of patients.
