Prognosis of Lung Cancer Caused by Exposure to Asbestos

Lung cancer caused by asbestos has a 16.2 month average life expectancy in the United States. In order to evaluate the prognosis of asbestos-related lung cancer, it is best to consult with a lung cancer specialist. A improved prognosis may be achieved with the use of treatments such as surgery, chemotherapy, and immunotherapy.

How Long Can You Expect to Live If You Have Lung Cancer Caused by Asbestos?

In terms of prognosis, patients with asbestos-related lung cancer have a comparable outlook to those with other types of lung cancer.

The average prognosis for asbestos-related lung cancer was 16.2 months in a 2009 Japanese study, while the average prognosis for lung cancer that was not caused by asbestos was 17.2 months. After receiving treatment, 25 percent of the patients with asbestos-related lung cancer lived longer than five years. There was no evidence that asbestos exposure significantly improved or worsened the prognosis of lung cancer patients.

For mesothelioma and other asbestos-related diseases, early diagnosis allows patients to qualify for more effective treatment choices that increase their chances of surviving.

In many cases, individuals are not eligible for surgery or other effective lung cancer treatment choices because asbestos-related diseases develop slowly and are commonly discovered in their later stages.

Patients who have been exposed to asbestos on a regular basis — particularly those who have a history of smoking cigarettes — should consider yearly lung cancer screenings to detect malignancies before they become irreversibly damaged or cancerous.

A low-dose CT scan is used for lung cancer screening because it can detect cancers forming at an early stage. Workers with a history of asbestos exposure may also benefit from regular spirometry tests, according to a study published in 2017. Spirometry tests can detect workers who have weakened lung function and may be at risk of developing lung cancer.

What Factors Influence the Prognosis of Lung Cancer?

The following are the most often observed prognostic variables for asbestos-related lung cancer:

  • Identifying the cancer’s type and stage
  • The patient’s age and general health are taken into consideration.
  • Examination of the lungs, including a review of smoking history

Your prognosis, on the other hand, is not a fixed figure. Patients with mesothelioma and lung cancer may be able to extend their lives with treatment, which is something that both diseases have in common.

Patients with asbestos-related cancer may benefit from treatments such as tumor-removal surgery, chemotherapy, radiation therapy, and immunotherapy, all of which can prolong their lives.

Some prognostic factors are favorable, which means they will have a tendency to enhance the duration of your life, whilst others have a negative impact on your prognosis and will tend to shorten your life. Patients can have a combination of prognostic variables that are both bad and favorable.

Survival Rates for Lung Cancer are influenced by the stage of the Cancer

Patients’ prognosis is heavily influenced by the stage of their cancer, which is just one aspect among many.

Generally speaking, lung cancer patients who are diagnosed at an early stage have a better prognosis and have a longer survival rate than those who are diagnosed later.

Mortality Rates for Lung Cancer in the First Five Years

It is estimated that local spread, which represents stages 1 and 2, has a five-year survival rate of 61 percent in the United States.

Regional dissemination, which corresponds to stage 3, has a five-year survival rate of 35% compared to stage 1.

It is estimated that just 6 percent of people survive five years after being exposed to distant spread, which defines stage 4. Obtainable through the American Cancer Society in January 2020.

Survival Rates for Lung Cancer Patients Depending on the Type

Small cell lung cancer and non-small cell lung cancer are the two most common kinds of lung cancer, and they have significantly differing survival rates. Small cell survival, in particular, is much shorter than non-small cell survival.

Small cell lung cancer is a more aggressive kind of lung cancer with a poorer prognosis than other types of lung cancer:

  • Twenty-seven percent of those who contract localized spread will survive for five years.
  • The survival percentage of regional dissemination is only 16 percent after five years.
  • The survival percentage of distant spread is only 3 percent after five years.

Even non-small cell lung cancer contains cell subgroups that have varying prognoses. In contrast to other types of non-small cell lung cancer, adenocarcinoma has a slightly better prognosis than other types of the disease.

According to a 2011 study, adenocarcinoma patients had a median survival time of 8.4 months, whereas all other non-small cell lung cancer patients had a median survival time of 8.1 months. Researchers have discovered comparable results in other studies, and they believe that the lung cancer numbers are relevant, despite the fact that the difference is tiny.

Prognosis of Lung Cancer in the Presence of Asbestos Exposure

Asbestos exposure does not appear to be a significant predictive factor in people with lung cancer.

When it comes to lung cancer, people with asbestos-related lung cancer have a prognosis that is similar to that of patients with lung cancer caused by another carcinogen such as cigarette smoking.

While prognostic indicators and survival statistics can be established through studies and scientific analysis, they are unable to account for individual differences in health and survival. There are some people who outlive their prognosis for no apparent reason, while others live longer lives as a result of vigorous treatment or involvement in clinical trials that provided them with access to ground-breaking medications such as immunotherapy, among others.

How Do Doctors Establish a Link Between Lung Cancer and Asbestos?

The Helsinki Criteria were entrenched in 1997 and are based on international standards. These guidelines assist doctors in determining whether asbestos is a contributing factor to respiratory disorders.

Criteria for diagnosing asbestos-related lung cancer include:

Latency Period: To be considered asbestos-related lung cancer, the disease must have arisen at least ten years after the initial asbestos exposure.

Evidence of Asbestos Exposure: Asbestosis, elevated levels of asbestos fibers in the lungs, and annual exposure levels of at least 25 fibers per milliliter of air are all possible indicators. At this skill level, you’d be working on ships or other large-scale construction projects.

Lung Cancer and Asbestosis

Lung cancer and asbestosis often go hand in hand. As asbestos fibers build in the lungs, the risk of both increases.

Patients with asbestosis are more likely to have been exposed to asbestos, which increases their risk of developing lung cancer.

What are the form of lung cancer that Asbestos causes?

It is possible to get lung cancer from exposure to asbestos, regardless of the form. Cell type is a subcategory for non-small and small-cell lung cancer classifications. A history of smoking raises a person’s risk of developing asbestos-related lung cancer. Pleural mesothelioma, which develops outside the lungs and is not considered lung cancer, is also caused by asbestos.

How common is lung cancer among asbestos exposure victims?

Asbestos exposure does not cause lung cancer or other asbestos-related disorders in every person who is exposed to it. As a person’s exposure to asbestos increases, so does their risk of developing a disease. Exposure to concentrated asbestos over a long period of time is the most dangerous.

Is there a distinction between mesothelioma and lung cancer caused by asbestos exposure?

Lung cancers of every type develop from within the lungs. Mesothelioma is a form of cancer that affects the lining of the lungs, the chest cavity, and the abdomen, although it is distinct from other forms of cancer. Both sorts of sickness can be brought on by asbestos exposure.
