Any Information About Non-Small Cell Lung Cancer?

What is non-small cell lung cancer?

Non-small cell lung cancer (NSCLC) is a disease in which malignant cells form in the tissues of the lung. It is the most common type of lung cancer. Smoking is the major risk factor for non-small cell lung cancer.

Symptoms of non-small cell lung cancer include bronchitis, pneumonia, headache, bone pain, balance problems, yellow skin or eyes, arm numbness and so on.

Tests commonly used to examine or diagnose NSCLC include imaging tests, sputum cytology, fine-needle aspiration biopsy, bronchoscopy, endoscopic ultrasound, thoracoscopy, mediastinoscopy, etc.

What are the types of non-small cell lung cancer?

The following are the subtypes of non-small cell lung cancer, they are:

  • Adenocarcinoma: It starts in cells in your air sacs that make mucus and other substances, is usually found in outer parts of the lung.
  • Squamous cell (epidermoid) carcinoma: It starts in early versions of squamous cells, which are flat cells that line the inside of the airways in the lungs. It tends to be found in the central part of the lungs, near bronchus.
  • Large cell (undifferentiated) carcinoma: It can appear in any part of the lung, and tends to grow and spread quickly.

How to treat non-small cell lung cancer?

There are several types of treatments used for patients with non-small cell lung cancer:

  • Surgery: It is advisable to remove part of or all of the lung to destroy cancer cells in early stage.
  • Chemotherapy: It uses drugs to kill cancer cells.
  • Radiation therapy: It uses high-energy beams to kill cancer cells that remain after surgery.
  • Targeted therapy: It can stop cancer cells from growing or spreading around.
  • Laser and photodynamic therapy (PDT): It kills cancer cells and helps avoid damage to healthy tissue.
  • Elecctrocautery
  • Cryosurgery

 

What are the clinical trials for non-small cell lung cancer?

The clinical trials for non-small cell lung cancer include:

  • There are some new types of treatments being tested in clinical trials, like chemoprevention, radiosensitizers, and new combinations.
  • The side effects caused by treatments for non-small cell lung cancer are being studied.
  • The follow-up tests needed for non-small cell lung cancer.

What is the prognosis of non-small cell lung cancer?

The prognosis of non-small cell lung cancer depends greatly on the stage diagnosed:

  • The 5-year survival rate for stage IA is about 49%-75%.
  • The 5-year survival rate for stage IB is about 45%-55%.
  • The 5-year survival rate for stage IIA is about 30%-50%.
  • The 5-year survival rate for stage IIB is about 31%-40%.
  • The 5-year survival rate for stage IIIA is about 14%-35%.
  • The 5-year survival rate for stage IIIB is about 2%-5%.
  • The 5-year survival rate for stage IV is about 1%.
