Lung Cancer

Lungs are exposed to a lot of toxic substances we inhale, such as pollution or tobacco, that's why lung cancer is so frequent.

There are two kinds of lung cancers: small cell and non-small cell lung cancer (the most frequent). These two forms do not growth identically and have different treatments.

The small cell lung cancer is the more serious because it cannot be detected early, and most of the time, by the time it is discovered, cancer has spread to other organs. There are three major types of small cell lung cancer:

  • Small cell carcinoma
  • Mixed small cell/large cell
  • Combined small cell carcinoma

Non-small cell lung cancer is the most common type of lung cancer. It usually spreads more slowly than some other lung cancers. There are three major types of non-small cell lung cancer:

  • Squamous cell carcinoma
  • Adenocarcinoma
  • Large cell carcinoma

When cancer strikes the lining of the lungs - otherwise known as the pleura - the disease that results is referred to as pleural mesothelioma. Technically speaking, the pleura is a sac which contains the lungs as well as a thin membrane known as the mesothelium, which secretes a vital fluid that enables the lungs to expand and contract during the breathing process.

Treatments for Lung Cancer and Procedures

Surgery, radiation therapy and chemotherapy (used alone or in various combinations) are the standard methods used to treat lung cancer. The choice of treatment depends on many factors, including the type of tumor, the extent of the disease when it is diagnosed, the age and general health of the patient and other variables.

For small cell cancers, only chemotherapy can be efficient. Sometimes, thoracic radiotherapy is also associated. As the risk of brain metastasis is very high (blood goes directly from lungs to brain), a prophylactic skull radiation exposure is done.

Surgical procedures that may be employed include wedge or segmental resection (removal of a portion of the affected lungs), lobectomy (removal of the entire lobe of the lung) or pneumonectomy (removal of the entire right or left lung).

For non-small cell cancers, if the tumor can be removed surgically, the surgeon will remove one lobe or the entire affected lung (depending on the size and location of the tumor) and the closest lymph nodes, which can contain cancerous cells. If the patient is too weak to have an operation, radiotherapy associated to chemotherapy can be done instead. When the tumor has spread too much and is not removable, or if there are metastases, patient is treated by radiotherapy along with chemotherapy.

For cancer of the pleural mesothelioma, treatment options are limited. Only a handful of mesothelioma patients afflicted with this form of the disease are candidates for surgery to remove tumors, especially since the tumors are often large and widespread by the time of diagnosis.

If only outer pleuron is affected, chemotherapy can be efficient. The possibility of surgery has to be discussed for every patient specifically. Most of the time, both pleura and lung are removed, and radiotherapy is associated. Surgery may be an option later, if the oncologist thinks the removal of a lung would benefit the patient.

More often, pleural mesothelioma patients are treated with radiation or chemotherapy.

Tchnologey Used for Treatment of Lung Cancer

Apart from surgery and chemotherapy, the new age technology used to treat lung cancer include Radiology and Radiation Oncology, which are advanced imaging technology that can be used to detect lung cancer.

Technologies for detection of cancer:

  • Computerized Tomography (CT)
  • Nuclear Medicine
  • MRI
  • Ultrasound
  • PET Fusion

New cutting-edge equipments include the CyberKnife® robotic radiosurgery, which are at the cutting edge of this technology – both offering pain-free non-invasive treatment with far greater accuracy and speed. Other leading edge treatment technologies available include:

  • Robotic Surgical System
  • Trilogy Image Guided Radiation Therapy System (IGRT)
  • Intensity Modulated Radiation Therapy System (IMRT)
