What Are The Survival Rates For Stage 4 Lung Cancer
Stage 4 lung cancer survival rates measure how many people are living a certain number of years after they were diagnosed with stage 4 lung cancer.
For example, a 5-year survival rate of 6 percent means that people with stage 4 lung cancer are, on average, about 6 percent as likely to survive for at least 5 years as people who dont have lung cancer.
Cancer survival rates are based on statistics from the NCIs Surveillance, Epidemiology, and End Results Program database.
Keep in mind that survival rates are only estimates. Everyones body responds to the disease and its treatment differently.
Relative survival rates also dont take into account recent improvements in treatment. Theyre based on diagnosis and treatment from at least 5 years earlier. New treatments are being researched and improved on every day.
The following provided by the ACS are based on people who were diagnosed with stage 4 lung cancer between 2010 and 2016.
The treatment options for late stage 4a or 4b lung cancer vary depending on several factors, such as:
- how far the cancer has spread
- whether any gene mutations have occurred
- your health in general
Before treatment for stage 4 lung cancer starts, your tumor may be tested for genetic mutations. According to a 2015 research review , one of these mutations is in the EGFR gene. If the gene is mutated in your cancer cells, you may receive a targeted therapy drug.
Stage 4 Adenocarcinoma Lung Cancer Life Expectancy
- Histology – what looks like a cell under the microscope. Adenocarcinoma is a histological subtype of non-small cell lung cancer. Other subtypes of small cell lung cancer do not include squamous cell lung cancer, large cell lung cancer and some uncommon types. Small cell lung cancer is another major type of lung cancer.
- Biomarkers – profiles of mutations or characteristics, as well as any other unique markers are found in a person’s cancer, which allows for increased cancer.
How Long Do You Live With Stage 4 Lung Cancer
Its true that life expectancy statistics dont paint a pretty picture, and its so normal to feel anxious, worried, concerned, and fearful about the future. But advances in science and research mean were seeing new and emerging treatments, together with greater research, and those living with lung cancer can participate in an increasing number of clinical trials.

How long do you live with stage four lung cancer? When people ask that question, I think, I remember the time when I first saw the statistics on Google about stage four lung cancer and how scared I felt when I looked at the numbers. Over the years Ive learned that its about how you interpret statistics rather than the numbers itself.
Numbers may be low, but they may also represent what was available at the time in terms of treatment, and because statistics represent numbers from years ago, and knowing now that there are so many new advancing research, advancing therapies that are improving the outcomes of stage four lung cancer, I know that those statistics are changing and its so important to keep that in mind when you look at the numbers.

Incidence Of T790m Before And After Egfr
MPEs were sampled from 317 patients before they underwent EGFR-TKI treatment. De novo T790M mutations were detected in seven patients by direct sequencing. All seven patients had concomitant L858R mutations. Of these, six patients received EGFR-TKI . All six patients had progressive disease, with median progression-free survival after EGFR-TKI therapy of 1.6 months .
99 patients with acquired resistance to EGFR-TKIs had MPEs sampled after EGFR-TKI therapy. Secondary T790M mutations were detected in 48 patients. In 23 out of 48 patients, this secondary mutation was detected in conjunction with L858R mutations, and in 25 patients, it was detected in conjunction with Del-19. Among the 48 patients with secondary T790M mutations, 16 patients underwent MPE sampling before EGFR-TKI treatment. No primary T790M mutations were detected in EGFR-TKI-naÃ¯ve MPEs.
Between the patients with and without secondary T790M mutations, there were no significant differences in clinical characteristics, including sex, age, smoking, ECOG PS, using gefitinib or erlotinib, stage M1a or M1b, the timing of MPE development and prior chemotherapy use .
Discussion Of Management Of Stage Iv Non
NSCLC is the leading cause of cancer-related deaths worldwide. Brain, bone, liver, and adrenal gland are the most common extrapulmonary sites of distant metastases. 20-50% of NSCLC will present with metastatic disease. Stage IV NSCLC cancer has an overall median survival time of 7-11 months.
In the past, patients with stage IV disease were generally believed to be incurable. Patients with oligometastatic disease represent a distinct subset. After full evaluation, approximately 7% of patients with metastatic disease will have solitary metastasis. There is evidence that in such patients, survival benefit can be achieved with surgical resection.
Accurate clinical staging is of utmost importance before embarking on curative surgery. FDG-PET/CT plays an important role in decision making and should be done if radical treatment is considered. The overall 5-year survival rate is about 28% for patients with satellite nodules and 21% for patients with ipsilateral pulmonary nodules. In patients with brain metastases, surgical resection achieves 5-year survival rates between 11% and 30%, and those with adrenalectomy for adrenal metastases have 5-year survival rates of 26%.
Most of the data on curative management of oligometastatic NSCLC include patient with adrenal metastasis, brain metastasis, and few selected reports of patients with lung cancer with only a malignant pleural effusion and no other metastatic sites who have long-term cures with chemotherapy and surgery.

Nsclc That Has Spread To Only One Other Site
Cancer that is limited in the lungs and has only spread to one other site is not common, but it can sometimes be treated with surgery and/or radiation therapy to treat the area of cancer spread, followed by treatment of the cancer in the lung. For example, a single tumor in the brain may be treated with surgery or stereotactic radiation, or surgery followed by radiation to the whole brain. Treatment for the lung tumor is then based on its T and N stages, and may include surgery, chemo, radiation, or some of these in combination.
How Do Healthcare Providers Diagnose Small Cell Lung Cancer
Chest X-rays are typically the first step to evaluate someone for any type of lung cancer. If images show suspicious spots on your lung, a healthcare provider may order one or more of these diagnostic tests:
- Imaging scans: Computed tomography and positron emission tomography scans detect lung tumors. CT scans are the primary way to diagnose lung cancer. These tests also can help gauge cancer spread.
- Biopsy: A needle biopsy removes tissue samples from your lungs. Lab pathologists check the biopsy for cancer cells.
- Bronchoscopy: Using a bronchoscope, your provider looks inside of your lungs airways for tumors. At the same time, they may remove tissue samples to biopsy.
What are the stages of small cell lung cancer?
Healthcare providers use a two-stage system to diagnose the spread of small cell lung cancer. This information also helps guide treatment. The two stages of small cell lung cancer are:
- Limited stage: This means theres cancer in one of your lungs that may have spread to an area between your lungs or to lymph nodes just above your collarbone. About 1 out of 3 people with small cell lung cancer have limited stage cancer at diagnosis.
- Extensive stage: In extensive stage, the cancer has spread to your other lung or beyond your lungs to lymph nodes. It also may have spread to your bones, brain and other organs.

Treatment Of Stage I Non
For information about the treatments listed below, see the Treatment Option Overview section.
- Surgery to remove cancer that has spread to the brain, followed by radiation therapy to the whole brain.
- Stereotactic radiosurgery for tumors that have spread to the brain and cannot be treated with surgery.
- A clinical trial of new drugs and combinations of treatments.
Use our clinical trial search to find NCI-supported cancer clinical trials that are accepting patients. You can search for trials based on the type of cancer, the age of the patient, and where the trials are being done. General information about clinical trials is also available.
Factors Influencing Survival Rates
The variability in survival rates highlights one key reality about stage 4 lung cancer: no two people have the same disease. Arguably more than any other stage of the disease, stage 4 lung cancer survival is influenced by multiple factors. Some of these are fixed and others can be changed .
There are seven factors known to influence survival times in people with stage 4 NSCLC.
How Will My Doctor Check For Stage Iv
Imaging tests. Your doctor may use X-rays, CT scans, or PET scans to see if new tumors have formed in your body and check how large they are. High-resolution CT and PET scans are good at finding tiny tumors that might not show up on an X-ray.
Tissue biopsy. If your doctor suspects your lung cancer has spread to other organs, you may get a biopsy to confirm or rule out cancer in those areas. Your doctor may use a hollow needle to remove a small sample of tissue from your lymph nodes or liver, for instance. A specialist called a pathologist will look at it under a microscope to see if there are cancer cells. Genetic tests on the tissue can also identify specific features of the cancer.
If Lung Cancer Is Suspected A Biopsy Is Done
One of the following types of biopsies is usually used:
One or more of the following laboratory tests may be done to study the tissue samples:
- Molecular test: A laboratory test to check for certain genes, proteins, or other molecules in a sample of tissue, blood, or other body fluid. Molecular tests check for certain gene or chromosome changes that occur in non-small cell lung cancer.
- Immunohistochemistry: A laboratory test that uses antibodies to check for certain antigens in a sample of a patients tissue. The antibodies are usually linked to an enzyme or a fluorescent dye. After the antibodies bind to a specific antigen in the tissue sample, the enzyme or dye is activated, and the antigen can then be seen under a microscope. This type of test is used to help diagnose cancer and to help tell one type of cancer from another type of cancer.

What Are The Symptoms
The symptoms you had in earlier stages of the disease may continue or get worse. Some problems you may have are:
- Cough that won’t go away
- Chest pain that gets worse when you breathe or cough
- Shortness of breath
- Loss of appetite and weight loss
Other symptoms may appear as lung cancer spreads to different parts of your body. If it moves into the brain or spinal cord, you may feel dizzy, get headaches, or have trouble keeping your balance. If it spreads to the liver, your skin and eyes may turn yellow . You may feel pain at the sites of the tumor.
What Causes Small Cell Lung Cancer
While anyone can get lung cancer, people who smoke, used to smoke or who are exposed to tobacco smoke have an increased risk of developing small cell lung cancer. Other risk factors include:
- Exposure to radiation from cancer treatments or imaging scans.
- Exposure to radon gas. Radon is a colorless radioactive gas that may seep into homes and other buildings.
- Exposure to workplace hazards like asbestos, arsenic, nickel, tar or toxic chemicals.
- Having a family history of lung cancer.
- Having human immunodeficiency virus .

Treatment Expertise For All Stages
MSK led the way in setting the standard of care for treating every stage of cell lung cancer. Doctors everywhere follow best practices developed at MSK. For example, MSK led a large research study that showed the standard treatment for stage 1 non-small cell lung cancer should be a lobectomy. In this procedure, a complete lobe of the lung is removed. There are 3 lobes in the right lung and 2 in the left. MSK also helped determine the best time to give chemotherapy to people who have stage 2 and 3 cancer.
Advances made at MSK in 2021 offer new hope to people facing some of the most difficult and complex cancers. MSK researchers and doctors played a lead role in clinical trials that led to a new drug in 2021. The U.S. Food and Drug Administration approved a drug that targets a protein, called KRAS, that fuels cancer growth. This protein may cause 1 out of 4 cases of lung cancers, but for decades it was considered undruggable. This treatment, called sotorasib , is a new option for some people who have stage 3 or 4 non-small cell lung cancer.
What Is Small Cell Lung Cancer
Small cell lung cancer is a rare fast-growing lung cancer. Small cell lung cancer can affect anyone, but it typically affects people who have a long history of tobacco use, specifically smoking cigarettes. Healthcare providers can cure some people if the disease is found early for others, they can help them live longer. The only way to prevent small cell lung cancer is to stop smoking.
How common is this condition?
How does small cell lung cancer affect my body?
Small cell lung cancer starts when healthy cells in your lungs mutate or change into cancerous cells. These cells then divide and multiply uncontrollably. Eventually, the cancerous cells clump together in masses in your lungs.
These tumors may shed cancer cells that your blood or lymph pick up and carry throughout your body.
Small cell lung cancer typically spreads to:
- Adrenal glands. These glands are located near your kidneys.
Once the cells have spread, they may create new cancerous tumors in your lymph nodes and organs. Small cell lung cancer may also cause fluid to build up in your lungs or in the space around your lungs. It can make your lung collapse by pushing air out of your lung. This is called a pleural effusion.
There are two types of small cell lung cancer:

Getting Answers: A Series Of Little Miracles
One morning, Tabitha awoke to the sight of a large nodule sticking out of her neck. As someone very in tune with her body, she knew something was wrong. Her first concern was that it was somehow related to emerging issues she was having with her thyroid. She met with a head and neck surgeon who, prior to committing to surgically removing both the nodule and a portion of her thyroid, insisted on an MRI and CT scan. Tabitha, it turned out, had a 5 cm mass on her left lung.
From this lung cancer detection, things moved quickly through what she refers to as a series of little miracles. Despite a typically three-week waitlist, a thoracic oncologist saw Tabitha the very same day her scans were performed. He immediately did biomarker testing. Tabitha, a 35-year-old mother of two, had Stage 4 adenocarcinoma, 29 brain metastases, and the ALK+ mutation.
Location And Type Of Lung Cancer
There are many different types and subtypes of NSCLC, some of which are more aggressive than others. The three most common types are:
- Lung adenocarcinoma, the most common form of the disease that mainly develops in the outer edges of the lungs
- Squamous cell lung carcinoma, accounts for 25% to 30% of lung cancer cases and develops mainly in the airways
- Large cell lung carcinoma, an uncommon type of NSCLC that can develop anywhere in the lungs and tends to be more aggressive than other types
Research shows that the differences between these types influence survival rates. Moreover, the location of the tumorwhether in the airways or in lung tissues themselvescan also have an impact on survivability.
|Large cell lung carcinoma
While research on each NSCLC type in stage 4 is limited, survival rates are generally lower than the reported overall five-year survival rates, consistent with previous data reported.

Diagnosis And Prognosis Of Stage 4 Lung Adenocarcinoma
The case is of a 64-year-old gentleman who presents with a headache and some visual abnormalitieshis left eye in some confusion. He eventually is evaluated by head of CT and is shown to have an occipital lesion on the right side. He subsequently has an evaluation of his chest, initially by chest x-ray and then by chest CT, which shows a 2.2-cm, left-lower lobe mass associated with some mediastinal adenopathy. A PET scan is subsequently done and it shows, in addition to the left lower lobe mass in the mediastinal disease, several boney sites that are highly suggestive of metastatic disease. He ends up having a biopsy of the left lower lobe lesion that shows a moderately differentiated adenocarcinoma on immunohistochemical staining. It is positive for TTF-1 and morphologically consistent adenocarcinoma.
He is a current nonsmoker, but did have a 30-pack-a-year exposure to smoking in the past, having quit about 5 years ago. His adenocarcinoma biopsy was tested forEGFR,ALK,andROS1and they were all negative. He also had a PD-L1 stained that showed it to be about 15% staining percentage. And in follow-up to his CT scan of the brain, he had an MRI of the brain. In addition to the occipital lesion that was noted, there were also 8-mm lesions in the left frontal lobe as well as right temporal lobe. So, he had 3 total lesions in the brain.
