Non Small Cell Lung Cancer Life Expectancy At Stage 1, 2 And 3

Question: What is non small cell lung cancer with non squamous histology? What is life expectancy at sate 1, 2 and 3?

Answer: Lung cancer is a cancer which originates from the lungs. It is the primary disease of the lungs, and not the metastasis which is seen in the lungs, where the cause of cancer is some where else in the body such as breast, liver or kidney.

Lung cancer is of two types:

  • Non small cell lung cancer and
  • Small cell lung cancer.

Maximum numbers of lung cancers are non small cell lung cancer.

About 8 to 9 out of ten lung cancers are non small cell lung cancer.

Non Small Cell Lung Cancer Life Expectancy

Life expectancy of stages1, stage2, stage3:

5 years survival rate is taken as general guide line for percentage of patients who live at least 5 years after they are diagnosed for cancer.

  • Stage 1: 50% five year survival rate.
  • Stage2: 30% of five year survival rate.
  • Stage 3: 18 to 19% of five year survival rate.
  • Stage 4: 1% of five year survival rate.

Types Of Non Small Cell Lung Cancer

Non small cell lung cancer is grouped into three varieties:

  • Squamous cell carcinoma: they are often seen in smokers, they are found in middle compartment of lungs and near the bronchus.
  • Adenacarcinoma: this is found in outer region of the lung and account for 40 to 50% of non small cell lung cancer.
  • Large cell carcinoma: they can occur in any part of lung and the spread is very fast, so the prognosis of this type is worst. About 10% of lung cancer is of this variety. See also therapeutic massage for cancer patient

Non Small Cell Lung Cancer Stages

Staging of non small cell lung cancer:

  • Staging of cancer is done to determine how far the cancer has spread and what will be its prognosis.

Clinical staging and pathological staging:

  • Clinical staging involves the investigations available such as MRI, Pet scan, biopsy, symptoms.
  • Pathological staging involves the analysis of the tissue by cytology. It is more accurate of grading the cancer stage.

For the purpose to make the gradation method easier there is an international TNM method used for it.

  • T= It indicates the size of the main cancer growth, and whether it has infiltrated other nearby areas. (STAGE1 for general understanding)
  • N= indicates if it has spread to the nearby lymph nodes. (STAGE2)
  • M= indicates if the cancer has spread to other parts of the body. (STAGE3)

    I have stage 1b lung cancer, non-small cell discovered early at 2.54 cm. Received cyber-knife therapy and pt/ct continue to show inactivity after 1 year.

    My husband has non small cell lung cancer and we have been told that he will not survive surgery due to his lungs being bad with emphysema. Chemo is out of the question as is large doses of radiation for the same reason. He may be able to have a low dose of radiation therapy over 5 days. Does anyone know the survival rate with these odds?
