What are the 3 types of NSCLC?

There are three main subtypes of non-small cell lung cancer (NSCLC), including the following:

• Squamous cell carcinoma (25% of lung cancers).
• Adenocarcinoma (40% of lung cancers).
• Large cell carcinoma (10% of lung cancers).

Which is more aggressive SCLC or NSCLC?

Small cell cancers vary , depending on the expression of specific genes. Some types are more aggressive than others, but generally, small cell cancer is more aggressive than non-small cell lung cancer.

What are the two types of small cell lung cancer?

There are two different types of small cell lung cancer: small cell carcinoma and mixed small cell/large cell cancer or combined small cell lung cancer. The types of small cell lung cancer are named for the kinds of cells found in the cancer and how the cells look when viewed under a microscope.

Is adenocarcinoma small cell?

Adenocarcinoma – The most common subtype, which is slow growing and usually forms in the outer parts of the lungs. Squamous cell carcinoma – A very slow growing form of non-small cell lung cancer that often develops in one of the lungs’ airways (bronchi)

Can NSCLC become SCLC?

Resistance to tyrosine kinase inhibitors (TKIs) in epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC) is well established to be mediated by histological transformation to SCLC in 3%–14% of cases.

What is the survival rate of adenocarcinoma?

Survival rates vary significantly, depending on the type of adenocarcinoma. Women with breast cancer that has spread locally but not to distant organs may have a 5-year survival rate of around 85%. A person with an equivalent stage adenocarcinoma in the lung would have a survival rate of about 33%.

What’s the difference between NSCLC and SCLC?

In addition, SCLC has only two stages (a system used by doctors to define the extent of spread of a cancer ), while NSCLC is staged differently with another staging system (TNM, see staging below).

How is small cell lung cancer treated in NSCLC?

A special feature of NSCLC is the occurrence of histological transformation to small cell lung cancer (SCLC) in up to 14% of cases, which, in general, is accompanied by resistance to the original TKIs. SCLC transformed tumors may be treated with the classical platinum/etoposide regimen but thus far there are no definitive guidelines.

What are the different types of treatment for NSCLC?

These types of adjuvant therapy used for NSCLC include radiation therapy and systemic therapies, such as chemotherapy, targeted therapy, and immunotherapy. Each therapy is described below. Radiation therapy is the use of high energy x-rays or other particles to destroy cancer cells.

What is the second line setting for SCLC?

“The second-line setting of SCLC is a very challenging one clinically,” said Jacob Sands, MD, a physician at Dana-Farber Cancer Institute and an instructor of medicine at Harvard Medical School, in an interview with OncLive. “These are patients with resistant, rapidly progressing disease, and often declining functional status.
