There are two main types of lung cancer:

1. Non-small cell lung cancer (NSCLC), which includes:

- Adenocarcinoma

- Squamous cell carcinoma (or squamous cell carcinoma)

- Large cell lung carcinoma

2. Small cell lung cancer (SCLC) (also called neuroendocrine small cell carcinoma), which is less common but grows and spreads more quickly.

This information is generally provided in the pathophysiological report.

The TNM score is a classification system used to assess the stage of a cancer, plan treatment, and predict prognosis.

Three parameters must be taken into account:

• The T describes the size and extent of the primary tumor
• The N indicates whether the cancer faces a regional lymph node extension
• The M indicates whether the cancer has spread to other parts of the body, called metastases

This information can be found on the pathologic report or a consultation report.

NB: On the platform, it is a simplified version of the TNM stadium. In the search fields, only the first number following the letter must be selected (ex: “Pt1c N0i+ M0” = “T1N0M0”)

The stage of lung cancer is determined by the TNM system and helps guide treatment. The stages vary from I (cancer that is limited to the lung) to IV (cancer that has spread to other parts of the body).

Chemotherapy is a treatment that uses powerful drugs to destroy cancer cells by stopping them from multiplying or spreading in the body. Chemotherapy medications can be given intravenously (into a vein), orally (as tablets or capsules), or by subcutaneous injection (under the skin).

Chemotherapy may be used alone or in combination with other treatments such as surgery or radiation therapy, depending on the type and stage of the cancer, as well as the patient's overall health. While chemotherapy can be very effective in destroying cancer cells, it can also damage healthy cells, leading to side effects such as hair loss, fatigue, nausea and vomiting, and suppression of the immune system.

In the context of lung cancer, chemotherapy drugs that are often used are:

- Cisplatin

- Carboplatin

- Pemetrexed

- Gemcitabine

- Docetaxel.

- Etoposide

- Paclitaxel (Taxol)
