Cellular neuroendocrine lung cancer is often found to have local infiltration and lymph node metastasis because of poor cell differentiation, high malignancy and rapid growth, so the treatment effect is poor and the prognosis is poor. At present, there is no specific chemotherapy scheme for this type of lung cancer, and chemotherapy can only be carried out according to the chemotherapy scheme for non-small cell lung cancer, and the chemotherapy effect is not ideal. It is recommended to go to a large 3A hospital or a specialized hospital. During the treatment, compound wall-broken ganoderma lucidum spore powder can be taken to enhance anti-tumor immunity. Reduce the side effects of chemotherapy.
