Asbestos-Related Lung Cancer Treatment

How Is Asbestos Lung Cancer Treated?

Asbestos-related lung cancer treatment can involve various forms of surgery, chemotherapy and radiation. When you receive a lung cancer diagnosis, your doctor will explain what type of tumor you have. There are two main types of lung cancer: Small cell and non-small cell.

Small cell and non-small cell lung cancers grow, spread and react to treatments differently. When you receive your diagnosis, your doctor will also explain the stage your cancer is at in terms of its progression. Your specific cancer type will play an important role in determining the best treatment plan for you.

Exposure to asbestos is strongly associated with causing lung cancer, mesothelioma and several other severe respiratory diseases. Asbestos is the most common occupational risk factor for lung cancer, and workplace exposure significantly increases the chance of developing the disease.

Staging

The stage a patient’s cancer has progressed to may limit treatment options. Lung cancer can spread to the lymph nodes and distant organs as it progresses, making treatment increasingly difficult. The earlier the diagnosis, the more treatment options there are. This increases the likelihood of successful treatment.

Non-small cell lung cancers are commonly classified with a 4-stage system. A higher stage indicates more advanced disease.

Small cell lung cancer is staged using a 2-stage system: Limited stage or extensive stage. In limited stage, the cancer is only found in a single lung and possibly nearby lymph nodes. In extensive stage, the tumor has spread to both lungs or other organs.

Surgery

Surgery’s goal is to remove a tumor and nearby cancerous tissue, ideally eliminating the disease completely. The tumor’s size, its location and how far the cancer has spread affects how much tissue is removed.

Types of surgery for lung cancer include: Wedge resection, lobectomy and pneumonectomy. Wedge describes the shape of the portion of lung and tissue removed in a wedge resection. A lobectomy removes a lobe, or section, of a lung. A pneumonectomy removes an entire lung.

If the cancer is found in an early stage when spread is limited, curative surgery is preferred for its statistically high success rates. However, in advanced-stage cancer where a cure is unlikely, palliative surgery may be performed to relieve symptoms and make patients more comfortable.

In addition to a patient’s cancer stage, doctors look at the cancer’s type before recommending a curative surgery approach. Coexisting conditions, such as heart disease, could make a patient ineligible for surgery.

Surgery for Non-Small Cell Lung Cancer

Surgery patients with non-small cell lung cancer can experience a 50-75% chance of relapse-free 5-year survival. In most cases, non-small cell lung cancers are removed through lobectomy. If the patient has poor lung function, however, doctors may remove only a small wedge of the lung via surgical resection.

Surgery for Small Cell Lung Cancer

Surgery is an option only in a few special cases of small cell lung cancer. This is because small cell lung cancer spreads much more aggressively than non-small cell lung cancer. Although surgical treatment for small cell is rare, studies have reported positive results for the small percentage of patients with very limited disease.

Chemotherapy

When there is clear evidence that lung cancer has spread from the initial tumor, chemotherapy is recommended. This treatment is typically not curative for lung cancer, but has been known to reduce the size of tumors and kill cancer cells that have spread to the lymph nodes. For patients, this usually translates to a longer, more comfortable life.

Whether taken intravenously or in pill form, chemotherapy drugs target rapidly dividing cells. This kills cancer cells, but can also affect normal healthy cells including hair follicles, red and white blood cells and the cells that line the stomach.

Because nearly 50% of all patients who have a tumor surgically removed will experience relapse, about 80% of all lung cancer patients are considered for chemotherapy during the course of their treatment.

Chemotherapy for Non-Small Cell Lung Cancer

In the earliest stages of non-small cell lung cancer, chemotherapy is sometimes given before surgery to reduce tumor size and eliminate early spreading. Doctors call this approach neoadjuvant chemotherapy. For patients with limited lymph node involvement, chemotherapy can also be given post-surgery to kill any remaining cancer cells. This is known as adjuvant chemotherapy and helps prevent the chance of cancer recurrence.

For later stage cancers when surgery is no longer an option, chemotherapy is often administered with simultaneous radiation therapy. Known as combined chemoradiation therapy, this option often boasts survival rates higher than either treatment given alone or one after the other. This treatment is common if the cancer has spread to the mediastinal lymph nodes, which are located outside of the lung near the trachea and esophagus.

Chemotherapy for Small Cell Lung Cancer

For early-stage small cell lung cancer patients in otherwise good health, doctors recommend combined chemoradiation therapy. Small cell cancers are highly responsive to chemotherapy, and survival is significantly improved when it is combined with early radiation therapy.

Once the cancer enters the extensive stage and spreads to distant organs, doctors typically prescribe a platinum-based chemotherapy regimen. This will involve platinum containing drugs like cisplatin or carboplatin with one or more additional chemotherapy drugs.

Radiation Therapy

Radiation is an effective treatment for non-small cell lung cancer. When applied in early stages for non-small cell lung cancer, radiation therapy is associated with 5-year survival rates between 13% and 39%. While radiation can help with local control, it’s much less effective for small cell lung cancer. This is especially true when it’s already spread extensively.

When lung cancer patients aren’t eligible for surgery, radiation is often recommended. High-energy targeted radiation stops cancerous cell division and reduces the size of tumors. The amount of radiation administered is thousands of times greater than the amount used in X-ray imaging, but treatment is divided into doses to limit the damage done to healthy tissues.

Like surgery, radiation therapy is a local treatment that only affects cells in the treatment area. Response rates for radiation therapy are significantly high, but relapse is common. As a result, it’s more often used palliatively. It’s administered in small doses to reduce pain where tumors have spread. It can also be given to prevent or treat lung cancers that spread to the brain.

Clinical Trials and Emerging Treatments

Clinical trials test new drug combinations to improve treatment success rates while minimizing undesirable side effects. Many experimental or emerging lung cancer treatments are also used to treat other asbestos-related cancers such as mesothelioma, which develops on the lining of the lungs. Clinical trials for these treatments will often accept both lung cancer and mesothelioma patients.

A number of clinical trials studying combinations of immunotherapy and chemotherapy, targeted therapies and gene therapies are currently underway. Ask your doctor for more information about joining a clinical trial or speak with a Patient Advocate.

A 2021 study, for example, reported positive results combining photodynamic therapy with chemotherapy for lung cancer. Researchers reported improved disease control, reduced treatment resistance and increased overall effectiveness in cancer reduction compared to conventional options.

Asbestos Lung Cancer Doctors

If you have been diagnosed with asbestos-related lung cancer, you’ll likely see more than one type of doctor. Leading cancer facilities recommend a multimodal approach to treatment, meaning several doctors specializing in different areas will work together to treat one patient.

Because lung cancer is so prevalent — the second-most diagnosed cancer in the United States — there is no shortage of doctors who treat it. The number of doctors who specialize in asbestos-related lung diseases is much smaller. Treating asbestos lung cancer comes with a special set of circumstances and challenges.
