Types Of Stage 4 Lung Cancer
There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer .
NSCLC accounts for over 80% of all lung cancer cases and has 5 stages . Many NSCLC patients will be diagnosed in either stage 3 or stage 4.
SCLC is much less common and is classified into either a limited or extensive stage. With extensive stage SCLC, the cancer has spread throughout and beyond the lung. In most cases, this stage is equal to stage 4 NSCLC.

Table 1 Reported Clinical Activity of Neoadjuvant Trials in Patients with NSCLC
NEOSTAR was the first randomized phase II trial comparing nivolumab monotherapy and nivolumab and ipilimumab combination for 3 cycles before surgery . Forty-four patients were enrolled in each arm. Compared with nivolumab monotherapy, nivolumabplusipilimumab resulted in higher pCR rates , less viable tumor , higher MPR , and greater frequencies of effector, tissue-resident memory T cells . High percentages of baseline tumor cells with expression of PD-L1 was positively correlated with radiographic responses and pathologic tumor responses at the time of surgery.

The Immunosuppressive Effect Of Surgery During Peri
Surgery and anesthesia induce various metabolic and endocrine responses, which result in a generalized state of immunosuppression in the immediate post-operative period . Since initial reports of the prometastatic effects of surgery in early 1900s , numerous studies have been conducted to understand the mechanisms of surgery-induced immunosuppression in the development of cancer metastasis and poor clinical outcomes . Surgery-induced prometastatic effect is linked to tumor cell dissemination to nearby blood vessels, organs, and lymphatics . In addition, there are local and systematic release of growth factors , as well as impairment of innate and adaptive immunity . Thus, the frequency of metastatic spread correlates with the degree of surgical trauma during the operation . Adjuvant platinum-based systemic chemotherapy has been shown to decrease local and distant recurrence, presumably by eliminating factors that contribute to perioperative micrometastasis.

The Revised International System For Staging Lung Cancer
The Revised International System for Staging Lung Cancer, based on information from a clinical database of more than 5,000 patients, was adopted in 2010 bythe American Joint Committee on Cancer and the Union Internationale Contre leCancer. These revisions provide greater prognostic specificity forpatient groups however, the correlation between stage and prognosis predates the widespread availability of PET imaging.
Stage 4 Cancer Survival Rate
A patient whose cancer cells have invaded other organs aside from its origin is said to be in Stage IV cancer, which usually carries a grim prognosis compared to earlier stages of the disease. The five-year survival rate for patients in this stage may depend on different factors such as the type of cancer he has, his overall general health, the type of treatment used and the patient’s will power to overcome the disease. As mentioned above, the five-year survival rate is expressed as the percentage of patients who will probably live up to 5 years after diagnosis of the disease based on research on patients with the same type and stage of cancer. A 60% 5-year survival rate therefore indicates that it is estimated that 60 out of every 100 patients will live for 5 years after diagnosis while the rest will probably die. This is just an estimate and not an exact number, since many factors influence the progress of one’s disease. The following is a summary of the 5-year survival rates of different types of stage 4 cancer based on research:

How To Cope With Late Stage Cancer
A diagnosis of late stage cancer affects a person mentally and emotionally.
People who are approaching the end of their lives may experience fear of dying. Identifying the specific element of death that is frightening and taking steps to address it may make the fear easier to cope with.
People with late stage cancer may also feel lonely, as if no one else around truly understands their experience. A person who feels this way should consider opening up to a healthcare professional who has experience talking with people who have late stage cancer. These doctors and nurses, for example, are likely to have a deeper understanding of the experience.
The American Cancer Society observe that regret is another common emotion toward the end of life. Stepping away from thinking about the past can be difficult. It can help to identify and focus on priorities in the present and write letters or make recordings for loved ones to treasure later on.
However having late stage cancer makes a person feel, speaking about these feelings with a trusted person can be both useful and comforting.
Immunotherapy For Stage 4 Lung Cancer
Lung cancer cells can sometimes avoid being destroyed by the immune system. Immunotherapy medications can right this wrong and help the body fight cancer.
Immunotherapy can be used to treat both stage 4 NSCLC and extensive SCLC. It is usually administered alongside chemotherapy medications.
Immunotherapy can cause side effects such as fatigue and bowel movement problems, which should be reported to caregivers and doctors if they occur.

Lung Cancer Life Expectancy With Treatment
Treatment typically enhances the life expectancy of lung cancer patients. Stage 4 is considered advanced, meaning it is often not curable, and treatment can do very little to help. Nevertheless, patients may choose to undergo surgery to remove the tumors, chemotherapy, radiation, or another form of therapy. Individual responses to treatment influence the life expectancy of lung cancer patients.
Medical professionals often urge stage 4 lung cancer patients to transition to palliative care instead of typical treatment. Advanced lung cancer can become painful, so palliative care is a type of treatment that focuses on relieving lung cancer symptoms. Examples of palliative care include:
- Pain management or suppression medicine
- Counseling and emotional support

Interpreting Lung Cancer Survival Rates
Lung cancer is a very serious type of cancer and is often fatal. But thats slowly changing as research advances.
People who receive a diagnosis of early-stage lung cancer are surviving in growing numbers. According to the American Lung Association, about 541,000 people who received a lung cancer diagnosis at some point are still alive today.
If you receive a lung cancer diagnosis, your doctor may talk with you about probable survival rates. This number is a statistic based on large numbers of people with the same type and stage of cancer.
Your experience may be different. Your healthcare team can give you the best idea of what to expect based on your individual circumstances.
Potentially Curable If Caught Very Early
Despite the overall poor prognosis and the fact that the disease is mostly incurable, pancreatic cancer has the potential to be curable if caught very early. Up to 10 percent of patients who receive an early diagnosis become disease-free after treatment. For patients who are diagnosed before the tumor grows much or spreads, the average pancreatic cancer survival time is 3 to 3.5 years.

Survival Rates By Disease Extent
A second method estimates survival rates based on the extent of cancer in the body. This is the approach used by the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program. The SEER system classifies cancer in one of three broader categories:
- Localized: Cancer limited to the lungs
- Regional: Cancer that has spread to nearby lymph nodes or structures
- Distant: Metastatic cancer
Under the SEER classification system, distant disease and stage 4 cancer are synonymous.
The one drawback to the SEER approach is that stage 4a and 4b lung cancer are melded into one category. This generalized approach returns a much lower five-year survival estimate . It also fails to reflect the wide variability in stage 4 survival rates, particularly in people with limited metastases.

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.
Cancer Australia. Relative survival by stage at diagnosis . Available at: . Accessed April 2020.
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.

Characteristics Of Stage 4 Lung Cancers
Lung cancer is staged to classify the severity of the disease. The staging of NSCLC helps doctors choose the most appropriate course of treatment based on the likely outcome or prognosis.
The stage of lung cancer is determined using the TNM classification system, which categorizes the severity of the disease based on three conditions:
- The size and extent of the primary tumor
- Whether nearby lymph nodes have cancer cells in them
- Whether distant metastasis has occurred
With stage 4 lung cancer, all three of these conditions will have occurred. With that said, the extent of metastasis can vary along with the prognosis.
For this reason, the 2018-released TNM classification system broke down stage 4 NSCLC into two substages:
- Stage 4a lung cancer, in which cancer has spread within the chest to the opposite lung or to the lining around the lungs or the heart or to the fluid around the lungs or heart
- Stage 4b lung cancer, in which cancer has spread to one or multiple places in one or more distant organs, such as the brain, adrenal gland, bone, liver, or distant lymph nodes
Stage 4 lung cancer is incurable. Treatments, therefore, are focused on slowing the progression of the disease, minimizing symptoms, and maintaining an optimal quality of life.

Schema for Biomarker-Driven Precision Neoadjuvant Therapy for stage IA2-III NSCLC. The LCMC4 screening trial is an umbrella trial that is designed to detect actionable oncogenic drivers by NGS in patients with resectable, early-stage NSCLC. Patients whose tumors harbor one of these oncogenic drivers are matched to one of the available, effective targeted therapies for patients with metastatic NSCLC. Those patients whose tumors do not harbor actionable driver oncogenes will receive standard of care or investigational neoadjuvant nivolumab and platinum-based chemotherapy

Understanding Stage 3 Lung Cancer
Stage 3 lung cancer is sometimes referred to as locally advanced lung cancer. It has not yet traveled to distant parts of your body, but it has spread to lymph nodes in the middle of your chest or grown into other nearby tissues.
When it comes to determining prognosis and life expectancy, we can turn to the numbers. The Surveillance, Epidemiology, and End Results program maintains a database about cancer in the United States. It provides statistics about the 5-year relative survival rate for people with non-small cell lung cancer based on their stage at diagnosis. This is a percentage of how many people with a certain stage of lung cancer will be living in five years, compared to a similar group of people who dont have cancer. According to the most recent data of this kind, if your lung cancer has spread to nearby regions of your body , the 5-year relative survival rate is 30.8%. That means 30.8% of people with stage 3 lung cancer were still living five years after receiving a diagnosis.
The statistics in the SEER database reflect survival rates before many of these new lung cancer treatments emerged in fact, the first immunotherapy drug approved by the Food and Drug Administration was only granted that approval in late 2015. In a few years, well have a much clearer idea of lung cancer prognosis now that newer treatments are part of the equation.
General Information About Non
In This Section
NSCLC is any type of epithelial lung cancer other than small cell lung cancer . The most common types of NSCLC are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma, but there are several other types that occur less frequently, and all types can occur in unusual histologic variants. Although NSCLCs are associated with cigarette smoke, adenocarcinomas may be found in patients who never smoked.
As a class, NSCLC is usually less sensitive to chemotherapy and radiation therapy than SCLC. Patients with resectable disease may be cured by surgery or surgery followed by chemotherapy. Local control can be achieved with radiation therapy in many patients with unresectable disease, but cure is seen only in relatively few patients. Patients with locally advanced unresectable disease may achieve long-term survival with radiation therapy combined with chemotherapy. Patients with advanced metastatic disease may achieve improved survival and palliation of symptoms with chemotherapy, targeted agents, and other supportive measures.

Radiation Therapy For Lung Cancer Stage 4
Radiation therapy is often used to boost the effects of other stage 4 lung cancer treatments.
For example, radiation may be used after surgery in cases of stage 4A NSCLC or alongside chemotherapy treatments in stage 4B NSCLC or extensive stage SCLC.
The ACS also notes that radiation therapy may be used as the main treatment for stage 4 lung cancer if the patient cannot safely tolerate chemotherapy.
Your health care team can help determine if radiation therapy is right for your case. Radiation therapy also causes side effects like fatigue and hair loss, but if these are less severe than the side effects of chemotherapy, it may be a better fit for you.
Factors That Affect The Outlook Of The Disease
If youve received a diagnosis of stage 4 lung cancer, many factors will affect your outlook, including:
- Overall health: Commonly, if youre healthy when you receive your diagnosis, its an indication that you might have a better ability to tolerate life-extending treatments.
- Age: Although data regarding the outcomes of older people with lung cancer is limited, a small
Stage 4 lung cancer may be categorized as either:
- non-small cell lung cancer
- small cell lung cancer
The outlook differs somewhat between the two types. However, treatment is similar at stage 4 and focuses on slowing the progression of the disease and improving symptoms.
Non-small cell lung cancer is the more common type. According to the , about 13% of lung cancers are small cell lung cancers. Small cell lung cancers are more aggressive and may spread quickly.
