The concept of the tumor microenvironment (TME) dates back to 1863 when Rudolf Virchow established a connection between inflammation and cancer. However, it was not until 1889 that Stephen Paget's seed and soil theory introduced the important role of TME in cancer metastasis, highlighting the intricate relationship between tumors and their surrounding microenvironment.
Lung cancer is the most diagnosed and deadliest cancer worldwide, with 2.2 million cases in 2020 resulting in 1.8 million deaths. [3] Lung cancer is rare in those younger than 40; the average age at diagnosis is 70 years, and the average age at death 72. [2] Incidence and outcomes vary widely across the world, depending on patterns of tobacco use.
In males, researchers suggest that the overall reduction in cancer death rates is due in large part to a reduction in tobacco use over the last half century, estimating that the reduction in lung cancer caused by tobacco smoking accounts for about 40% of the overall reduction in cancer death rates in men and is responsible for preventing at least 146,000 lung cancer deaths in men during the ...
Unlike extensive-stage small cell lung cancer, limited-stage small cell lung cancer is potentially curable. [4] In limited small cell lung cancer, the median overall survival time is approximately 12–16 months, with five year survival rate of approximately 26% and long-term survival rate of approximately 4–5%.

The cancer stem cell model asserts that within a population of tumour cells, there is only a small subset of cells that are tumourigenic (able to form tumours). These cells are termed cancer stem cells (CSCs), and are marked by the ability to both self-renew and differentiate into non-tumourigenic progeny. The CSC model posits that the ...
Lung cancer is responsible for 1.3 million deaths worldwide annually and is the most common cause of cancer-related death in men and the second most common in women. According to the World Health Organization, lung cancer was responsible for approximately 10 million deaths in 2020. [2]
The most common as of 2018 are lung cancer (1.76 million deaths), colorectal cancer (860,000) stomach cancer (780,000), liver cancer (780,000), and breast cancer (620,000). [2] This makes invasive cancer the leading cause of death in the developed world and the second leading in the developing world . [ 25 ]
Non-small-cell lung cancer (NSCLC), or non-small-cell lung carcinoma, is any type of epithelial lung cancer other than small-cell lung cancer (SCLC). NSCLC accounts for about 85% of all lung cancers. [1] [2] [3] As a class, NSCLCs are relatively insensitive to chemotherapy, compared to small-cell carcinoma.
