Dr. Harsh Vardhan Puri explaining about Lung Cancer Treatment

What is lung cancer? Lung cancer is when cells of lungs mutate (change abnormally) and begin growing out of control. These cells grow in an unregulated manner.

They are divided into benign (noncancerous), meaning they do not grow into surrounding areas or spread in the body an malignant (cancerous) tumours grow into nearby tissues or spread to other parts of the body (metastasize).

How does lung cancer develop? This is a matter of debate but in general, cancer develops after the genetic material in cells changes abnormally and there is unregulated growth of these cells. When there are enough of these abnormal cells, they can form a tumour.

Lung cancer often is a result of chronic exposure to tobacco smoke, either from smoking or from being around second-hand smoke. It also is linked to exposure to certain substances like radon gas or asbestos, or from prior radiation treatment to or over the lungs. These days a very prominent cause of lung cancer specially in India which is rising at a rapid rate is air pollution and there are many studies correlating lung cancer to air pollution.

What are the types of Lung Cancer? There are two main types

Non-small cell lung cancer

Squamouscell carcinoma

Adenocarcinoma

Bronchoalveolarcarcinoma

Large-cell undifferentiated carcinoma

Smallcell lung cancer

What are the Stages of Lung Cancer?

Staging is important to plan treatment and is based:

Size

Location

Metastasis

The stages of lung cancer are: Stage 1: Confined to lung, not spread to the lymph nodes or distant organs. Surgery is the best modality at this stage.

Stage 2: Cancer has spread from to nearby lymph nodes. Surgery followed by adjuvant therapy is best treatment.

Stage 3: Cancer is in the lung and has spread to mediastinal lymph nodes. Chemotherapy may be recommended before and after surgery with adjuvant radiotherapy. Targeted therapies may be used after surgery.

Stage 4 (Metastatic): Cancer has progressed beyond the lung to distant organs. This advanced stage of cancer is commonly managed by non surgical methods like palliative chemoradiation and targeted therapies.

How is lung cancer diagnosed? Diagnostic phase is tailor basedaccording to each individual patient. Tests may include:

Blood Tests (Blood Draws) Several blood tests are required to help establish the diagnosis and plan the further course of treatment.

Imaging (Radiology) To obtain the most precise understanding of your cancer, your doctor may schedule you for different types of imaging that diagnose cancer. This may include Contrast Enhanced Computed Tomography (CECT) or Positron Emission Tomography(PET) or Magnetic Resonance Imaging(MRI).

Lung Biopsy (Pathology) If imaging or other screening tests show that there is atumour, a biopsy will be needed. This test takes a tiny sample of cells from abnormal areas of tissue. This of an image guidence depending on the location of the tumour.

Ultrasound guided Biopsy

CT (Computed Tomography) Guided biopsy

Endo Bronchial UltraSound Biopsy for Lymph Nodes or Centrally located tumours

What are the tests done to stage lung cancer? The clinical staging is important to treat and to prognosticate. This will require

Whole Body PET/CT Scan Positron emission tomography (PET) Scan is a special imaging modality wherein a small amounts of radioactive materials called radiotracers or radiopharmaceuticals are injected in to the veins. These radiotracers accumulate in areas where there may be tumour cells and will be detected using a special camera and a computer. By identifying changes at the cellular level, PET scan may detect the early onset of disease before other imaging tests can and also help in identifying whether the disease is limited to lungs or has spread beyond it.

MRI Brain Certain patients will require MRI of the brain to rule out spread to brain which sometimes is not picked up by PET scan.

Endo-Bronchial Ultrasound Guided staging of Mediastinal Lymph nodes This test is used to check for spread of the cancer to regional or Mediastinal Nodes. It involves the use of a special bronchoscope which has an ultrasound probe at its tip. This is used to visualise the lymph nodes from which needle biopsy is taken and which is then subjected to evaluation by Pathologists for presence of cancer cells

Mediastinoscopy This is a surgical procedure that is advised in patients with Lung Cancer to conclusively rule out the involvement of Mediastinal Nodes in the central part of the chest, which is the space between the heart, lungs, windpipe, and esophagus.
