Malignant lung cancer, with two surgeries and two recurrences, maintaining stable disease condition is fundamental

Lung Cancer Staging

In lung cancer, a tumor that grows in a solid organ, T usually represents the size or extent of the tumor. T0-T4 increase progressively, with T0 indicating no primary lesion and Tis indicating carcinoma in situ, both of which are relatively early-stage tumors. T4 tumors have invaded the mediastinum, heart, major blood vessels, and other areas, and have a poor prognosis.

N represents involved lymph nodes, as we know that tumors often metastasize through lymph nodes. It increases progressively from N0 to N3, with N0 indicating no lymph node metastasis and N3 indicating supraclavicular lymph node metastasis.

M represents distant metastasis. M0 indicates no distant metastasis, while M1 indicates distant metastasis. Many M1 patients even lose the opportunity for radical surgery.

1. The patient was diagnosed with a lung tumor in 2017, and at that time, pleural metastasis had already occurred, indicating a late stage.

2. The patient underwent postoperative radiotherapy and chemotherapy, but still developed metastatic lesions. Despite undergoing surgery again for the metastatic lesions, complete cure was not achieved, and soon thereafter, brain metastasis occurred, indicating a high malignant potential of the tumor.

3. The patient is currently undergoing targeted drug therapy. NKT cell immunotherapy can utilize immune cells to combat tumors without significant side effects. It is recommended to combine targeted drug therapy with NKT cell therapy to prolong survival and achieve long-term stability.
