How To Treat Lung Cancer: Lung Cancer Treatment

How To Treat Lung Cancer- Lung cancer is the largest cause of cancer-related mortality. Several lung cancers can be avoided. Inhaling cancer-causing chemicals such as cigarette smoke can cause precancerous alterations in lung tissue immediately after exposure. Cancer, on the other hand, usually changes over a period of time. It may typically be effectively treated if identified earlier enough.

Pre- Treatment Evaluation of Lung Cancer

  • A biopsy is frequently performed before therapy to identify whether cancer is diagnosed and, if so, what kind of cancer it is.
  • Medical imaging is used by doctors to assess the tumor’s stage. Treatment options (and predicted outcomes) are determined by the tumor’s stage. Chest X-rays and chest computed tomography are commonly used in imaging (CT). A PET/CT scan as well as MRI of the brain may also be used.
  • To see if you can tolerate surgery, you may have pulmonary as well as cardiac testing process.
  • Blood testing will establish if you are able to tolerate chemotherapy, targeted treatment, or immunotherapy.

How to treat Lung cancer

For many lung cancers, tumor genomic testing has become standard of care. These tests help your doctor in determining the best treatment for your disease. Early-stage lung cancer may be treated with traditional therapies such as surgery or radiation therapy.

Lung Cancer Surgery

Persons with early-stage cancer who are also in good overall condition are treated with surgery. The objective of surgery is to completely eliminate all tumor cells, resulting in a cure. Lung cancer is more common in smokers over the age of 50, who are more likely to have other chronic illnesses that raise the risk of surgery.

Radiotherapy for Lung Cancer

High-energy x-rays are used in radiation treatment to kill cancer cells and relieve symptoms. Doctors utilize it because:

  • As a primary therapy
  • To reduce the tumor before surgery
  • Following surgery to remove any remaining cancer cells in the treated region
  • To relieve symptoms of lung cancer that has progressed to the brain or other parts of the body.
How to treat Lung cancer

Radiotherapy can help reduce symptoms including bleeding, coughing, and discomfort in addition to targeting the tumor. Radiotherapy can be given alone or in combination with chemotherapy as a primary treatment rather than surgery. Patients with tiny, localized lung cancer who are not surgical candidates may benefit from stereotactic body radiation treatment (SBRT).

The elderly, persons with chronic heart failure, as well as patients using blood thinners who are at risk of postoperative haemorrhage are all poor candidates for surgery. SBRT employs tiny, concentrated radiation beams to monitor the lung tumor as it moves through the airway. It usually involves three to five sessions to administer extremely high levels of radiation to patients with localized, initial lung cancer who are unable to undergo surgery.

The external beam approach, which directs a beam of x-rays or protons directly onto the tumor, is most commonly used in radiation treatment. The treatment is spread out over 6 to 7 weeks in a series of treatments. A 3-D picture of the tumor acquired with CT scanning is used in three-dimensional conformal radiation treatment or intensity-modulated radiation therapy (IMRT).

This picture serves as the focus for a high levels of radiation beam that can adapt to the tumor’s size and shape. This approach reduces the amount of radiation that reaches surrounding healthy lung tissue.

Protons are used instead of x-rays in proton treatment. Protons are able to travel through normal tissue without causing damage.

Doctors utilise systemic medicines to treat cancer that has spread throughout the body or is expected to do so. Radiation, in combination with chemotherapy and immunotherapy, is used to treat cancer that has spread to the lymph nodes. Surgery may be performed before chemotherapy/radiation therapy in some cases.

Doctors often use systemic therapies including chemotherapy, targeted therapy, and/or immunotherapy to cure late-stage illness that has spread to certain other regions of the body. They may also utilize radiation therapy to consolidate any remaining illness and reduce symptoms following systemic treatment. Specific genetic tests performed on tumor cells obtained during a biopsy are usually used to determine the optimal therapy.

Chemotherapy for lung cancer

Chemotherapy is the administration of medications that destroy cancer cells. Chemotherapy is frequently given to patients via a direct injection into a vein or by a catheter inserted into a big vein. Following surgery, doctors frequently provide chemotherapy to remove microscopic illness. Chemotherapy can also help patients who are unable to have surgery by slowing tumor development and alleviating symptoms.

Doctors are looking at novel biologic drugs that may have less side effects and be equally efficient as chemotherapy. Chemotherapy is used to treat lung cancer at all stages. It can even help older people live longer if they are in excellent health. Some chemotherapy medicines make radiation treatment more effective. Others maintain the tumor cells alive long enough for radiation therapy to be effective.

Alternatively, they impede the capacity of cancer cells to repair themselves following radiation therapy. A increasing body of research suggests that chemotherapy with radiation is more effective than radiotherapy alone. There is, nevertheless, a significant danger of major adverse effects.

Chemotherapy can have a lot of negative effects. These include nausea and vomiting, as well as damage to infection-fighting white blood cells. Most of these adverse effects, however, may be avoided or treated.

Targeted Therapy

Monoclonal antibodies, which are man-made molecules, are used in targeted treatment. Invading foreign matter, like bacteria and viruses, are attacked by natural antibodies. Monoclonal antibodies recognize and attach to the surface of cancer cells in the same way as natural antibodies do. They may be combined with a chemotherapeutic medicine or radioactive substance by your doctor. The cancer-killing drug can then be delivered directly to the tumor cell by the antibody.

Immunotherapy

Immunotherapy is a cancer treatment that makes use of the body’s immune system. The detection of markers on the surface of tumor cells is required for this form of treatment.

How to treat Lung cancer

What effect does the kind of lung cancer have on the treatment method?

Lung cancer is divided into two categories, each with its own microscopic appearance:

Small-cell lung cancer (SCLC)

Small-cell lung cancer (SCLC) is most commonly seen in current or past smokers. SCLC is a more aggressive tumor than non-small cell lung cancer (NSCLC), and it is more liable to spread to other parts of the body. The most common treatment for SCLC is chemotherapy. Radiation treatment combined with chemotherapy may be used to treat lung cancers that have not spread further than the chest or other organs. Surgery is not a frequent therapy for SCLC since it spreads fast.

Your doctor may, however, perform surgery to take tissue samples for laboratory testing to diagnose the kind of lung cancer existing. Patients with SCLC may require extra brain radiation therapy. This slows the progression of cancer from lungs to the brain.

Non-Small-cell lung cancer (NSCLC)

Non-small-cell lung cancer develops gradually and spreads more slowly than small-cell lung cancer. Surgery and/or radiation therapy are routinely given to patients. Chemotherapy may be used as part of your treatment to boost the efficiency of surgery or radiation. Chemotherapy for NSCLC differs from that for SCLC. Various forms of NSCLC may also necessitate different methods of chemotherapy.

How does the stage of lung cancer influence treatment?

Small cell lung cancer:

To treat early-stage cancer, doctors utilize chemotherapy and radiation treatment (confined to the chest). The first or second dosage of chemotherapy is usually followed by radiation. The most typical radiation regimens are 6 weeks of once-daily radiation or 3 weeks of 2 times radiation.

Even if no cancer has been identified in the brain, the radiation oncologist may recommend brain radiation treatment for restricted stage illness.

Chemotherapy is typically used alone to treat advanced stage SCLC.

Even if no cancer has been identified in the brain, the radiation oncologist may recommend brain radiation treatment for advanced stage illness. In advanced stages of illness, there is little evidence for preventive brain radiation.

Consolidation radiotherapy to the bulky portions of the primary tumor in the chest may potentially be considered by the treatment team.

For illness recurrence or disease that remains after first treatment, radiotherapy or chemotherapy may help ease discomfort or even other symptoms. The airways can be kept open by radiotherapy or laser therapy, allowing patients to breathe more easily.

Non small cell lung cancer:

Early Stage

NSCLCs start off as extremely tiny tumors. To find the primary tumor, special testing may be required. Early-stage cancers are treated with surgery or stereotactic radiation treatment by doctors.

Advance Stage

When cancer has progressed to tissues around the lung, like the chest wall, diaphragm, or lymph nodes in the chest, doctors utilize a combination of treatments. Patients may get radiation treatment alone or in combination with surgery and/or chemotherapy, based on the particular location of their cancer.

Patients whose cancers have migrated further than the chest or into the opposing lung are treated with chemotherapy and targeted treatment. People with cancer that has progressed beyond the chest do not usually benefit from surgery. Chemotherapy extends life, while radiation treatment helps alleviate tumor-related symptoms. For individuals with NSCLC that has progressed to the brain, the doctor may propose brain surgery.

Any lung cancer sufferer should consider participating in a clinical trial to aid in the development of more effective therapies.

What occurs during radiation treatment?

High-energy x-rays (photons), gamma rays, or atomic particles are utilized in radiation treatment. It has a significantly greater impact on cells that divide fast, such as cancer cells, than on ones that do not. Most malignancies, including lung tumors, are formed up of cells that proliferate faster than normal lung tissue cells. This implies the tumor may be removed without causing harm to the surrounding tissues.

Radiotherapy works by destroying tumor cells’ DNA, preventing them from growing and producing new cancer cells. Normal bodily cells can also be injured, but they can heal themselves and resume normal function.

The aim is to deliver regular radiation doses big enough to kill a high proportion of quickly growing cancer cells while limiting harm to slower-dividing normal tissue cells in the same location.
