Small cell lung cancer or oat cell carcinoma: Small cell lung cancer has a short doubling time and rapid progression, often accompanied by endocrine abnormalities or carcinoid syndrome; 

since patients have hematogenous metastasis in the early stage and are sensitive to radiotherapy and chemotherapy, the treatment of small cell lung cancer should be based on systemic chemotherapy, combined with radiotherapy and surgery as the main treatment methods.

Comprehensive treatment is the key to the successful treatment of small cell lung cancer.

Non-small cell lung cancer: About 80% of lung cancer patients belong to this type. This distinction is very important because the treatment plans for these two types of lung cancer are completely different.

Small cell lung cancer patients are mainly treated with chemotherapy, and surgical treatment does not play a major role in this type of lung cancer patients. On the other hand, surgical treatment is mainly suitable for patients with non-small cell lung cancer.

Currently, the more commonly used treatment methods include: surgical treatment, chemotherapy, radiotherapy, biological treatment, etc., none of which can completely cure the tumor. The defects of traditional treatments:

Surgery: Tumor patients often have poor immunity. Even if they are reluctant to undergo surgical treatment, they are often difficult to recover, but instead induce faster proliferation of cancer cells. 

In addition, surgical removal of tumor tissue often requires the removal of a part of normal tissue, which may cause certain postoperative sequelae and functional disorders.

Radiotherapy and chemotherapy: Although high doses of radiotherapy and chemotherapy can destroy or eliminate cancer cells, they also damage normal cells and cause toxic side effects. 

The toxins of radiotherapy and chemotherapy invade the human body, causing the patient’s body immunity to decline and the body to become weaker, thereby reducing the body’s sensitivity to radiotherapy and chemotherapy, resulting in lower efficacy of radiotherapy and chemotherapy. 

Therefore, higher doses can only be used to deal with it, thus forming a fatal cycle.

According to a report by the World Health Organization (WHO), the incidence of tumors in the world is now in a stage of continuous increase, and it is expected that the number of new cases per year will reach 17 million by 2025.

In my country, malignant tumors have become the most common cause of death. Due to the complexity of tumor diagnosis and the limitations of current diagnostic levels. 

Especially in developing countries, many patients are already in the middle and late stages when diagnosed, and have lost the opportunity for curative treatment.

With the transformation of the modern medical model from the biomedical model to the bio-psycho-social medical model, the treatment of tumors is no longer a simple mechanical pursuit of eliminating or shrinking tumor entities and killing tumor cells, but also taking into account the improvement of patients’ body immunity and mental symptoms, and improving the quality of life, a new health indicator.

Therefore, with the development of modern Chinese medicine immunology and Chinese medicine molecular biology technology, the concept of Chinese medicine immunotherapy for tumors has gradually come onto the stage of tumor treatment in the new era.
