What are the symptoms of stage 4 lung cancer?

Here we are going to share information on the topic “What are the symptoms of stage 4 lung cancer?” Lung cancer is classified into stages according to the extent of its spread throughout the body, just as other cancer forms. The cancer is generally more severe at higher stages.

What is lung cancer in stage 4?

Metastatic lung cancer, often known as stage 4 lung cancer, is an advanced form of the illness. When lung cancer reaches stage 4, it has progressed from its original location in the lung to other body parts.

When cancer cells split off from the primary tumor and travel throughout the body through the lymphatic or circulatory systems, this is known as metastasis. From the lung, the cancer cells frequently spread to the liver, brain, bones, and adrenal glands, where they may develop into new metastatic tumors. Since they are still composed of lung cancer cells, any metastatic tumors that continue to grow and spread to other parts of the body are still classified as lung cancer at that time.

Symptoms of stage 4 lung cancer

Symptoms can occasionally lead to the discovery of advanced lung cancer. The following signs and symptoms of lung cancer can appear at any stage; however, they are more likely to do so as the disease advances:

  • Persistent cough that gets worse
  • Hemoptysis (coughing up blood)
  • Spit contains blood
  • Chest pain that could get worse when you laugh, cough, or take deep breaths
  • Sibilant voice
  • Insufficient appetite
  • Inadvertent reduction of body mass
  • Breathlessness
  • Weakness or exhaustion
  • Wheezing
  • Recurring illnesses like pneumonia and bronchitis

The following symptoms could also appear if lung cancer spreads to other areas of the body:

  • Headaches, balance problems, dizziness, limb weakness or numbness, or seizures (if the cancer has spread to the brain)
  • A yellow complexion (if the cancer has spread to the liver)
  • Discomfort in the hips or back bones
  • Enlarged neck lymph nodes

There could be a less serious ailment causing these symptoms. Nevertheless, it’s crucial to see a doctor to assess these symptoms because many of them are dangerous, and they can help identify the underlying problem.

Testing for metastatic (stage 4) lung cancer

To check for lung cancer, doctors do a variety of tests, surgeries, and scans. They can be used to identify the stage of the cancer, confirm a diagnosis if one is suspected, or find out the symptoms of the cancer.

Using these methods, advanced or metastatic lung cancer can be identified:

  • If lung cancer has spread to the brain or spinal cord, magnetic resonance imaging (MRI) scans can help identify it by producing comprehensive images of the inside of the body.
  • Similar to magnetic resonance imaging (MRI) scans, computed tomography (CT) scans provide images of the interior of the body. They could be useful in determining whether lung cancer has progressed to the brain, liver, adrenal glands, lymph nodes, or other organs.
  • PET (positron emission tomography) scans can reveal the body’s cancer cell locations. Patients get a little injection of radioactive sugar, which is intended to circulate throughout the body, prior to a PET scan. The material would accumulate in any area(s) containing cancer cells, revealing the malignancy’s location and presence.
  • If lung cancer has spread to the bones, bone scans can help find out. These tests are comparable to PET scans in that a radioactive material injection is necessary, and the radioactive material will concentrate in the bones containing cancer cells.
  • A biopsy is required to obtain a definitive diagnosis of cancer. A sample of tissue or cells is taken, and a pathologist looks at it under a microscope to check for indications of malignancy.

Stage 4 non-small cell lung cancer

The more prevalent of the two main kinds of lung cancer is non-small cell lung cancer (NSCLC).

NSCLC stages, which span from stage 1 to stage 4, are established by taking into account a number of variables, such as the size of the primary lung tumor and if the disease has spread to lymph nodes in the vicinity of the lungs or elsewhere throughout the body.

When NSCLC reaches stage 4, it is metastatic, which means that it has progressed outside of the original lung. Stage 4 NSCLC is further divided into two substages: 4A and 4B, depending on how far it has spread.

Stage 4A non-small cell lung cancer: The tumor’s size and whether or not it has migrated to the lymph nodes can also fluctuate in stage 4A. It’s also possible that one or more of these are true:

Only one other place has cancer spread, such as the second lung (where the cancer did not originate) or an organ that is far away, like the kidney, liver, brain, or adrenal gland.

It has extended to the fluid, or lining, surrounding the heart and lungs.

Apart from the main tumors, there are other tumors in the lung.

Stage 4B non-small cell lung cancer: In this stage, the disease has progressed to numerous organs or locations far from the lung.

Although both of these substages of cancer may be referred to as stage 4, they may need distinct treatments. Although stage 4B is more prevalent, its prognosis is often worse, and its chances of survival are reduced.

Stage 4 small cell lung cancer

Small-cell lung cancer is the second most frequent kind of lung cancer after non-small-cell lung cancer (SCLC). Usually, SCLC is not divided into sequential phases. Rather, it’s referred to as either a limited or extensive stage.

Limited-stage small cell lung cancer (SCLC) is confined to one side of the chest, with the cancer only present in one lung and perhaps spreading to lymph nodes nearby. It’s possible that the disease is not at a limited stage if the lung has several tumors.

The metastatic nature of extensive-stage SCLC is comparable to that of stage 4 NSCLC. If SCLC has gone to any other part of the body, such as distant lymph nodes, the second lung, or the initial lung, it is deemed widespread.

Taking care of stage 4 metastatic lung cancer

It is difficult to treat lung cancer that has spread. Even in cases where treatment seems to be working, cancer at this stage may still spread, and tiny remnants of the disease may remain in the body and trigger a recurrence. As a result, the goal of treatment is usually to improve and prolong life by reducing symptoms and slowing the spread of the malignancy. A few things to think about are:

  • A patient should inquire about treatment expectations from a physician if they have advanced lung cancer.
  • In order to make sure that the treatment plan is appropriate, patients might even wish to get a second opinion from a different physician.
  • The medical team will assess how the course of therapy will affect overall health and well-being while also considering any possible adverse effects.

Options for treating metastatic lung cancer might differ based on a number of variables, including:

  • The kind of cancer
  • The location and spread of the cancer
  • the existence of underlying gene modifications, or mutations, that could be causing the cancer
  • The symptoms and general health of the patient
  • Preferences of the patient

Addressing Stage 4 of NSCLC Treatment for NSCLC could involve:

  • Surgery
  • Chemotherapy
  • Personalized treatment
  • Immunotherapy
  • Radiation treatment

A standard course of treatment for cancer that has migrated to another site—especially the brain—might involve radiation therapy and surgery to target the metastasized location. Next, attention turns to the lung, where a mix of radiation, chemotherapy, and surgery may be used as a form of treatment (depending on the specifics of the tumor).

Nevertheless, malignancies at this stage frequently have spread too far and call for systemic therapies that target the malignancy throughout the body.

Whether the main lung tumor has any particular genetic alterations that could be targeted is the first thing to take into account when selecting a systemic treatment. If so, the first line of treatment would probably be targeted therapy medications made to address these gene alterations. Other choices include immunotherapy, chemotherapy, or a combination.

Taking care of advanced-stage SCLC

Systemic therapies (like chemotherapy or immunotherapy) would be more beneficial than therapies (like radiation therapy or surgery) that focus on a particular area of the body because extensive-stage SCLC is cancer that has spread widely throughout the body. Similar to stage 4 NSCLC, the goals of treatment would probably be to stop the cancer from growing, manage symptoms, and prolong the patient’s life. At this point, the initial line of treatment is usually a mix of immunotherapy and chemotherapy, or either one alone.

Options for palliative care in stage 4 lung cancer

Palliative care is often provided to patients with advanced lung cancer, either in addition to other treatments or on its own (if the patient has chosen not to pursue standard treatment).

Palliative care focuses on treating both physical and emotional symptoms in an effort to enhance the quality of life for patients with life-threatening illnesses. This method places more emphasis on the patient and their needs than it does on the illness itself.

Palliative care, which is not the same as hospice, can help patients at any stage of their severe disease. It could also be beneficial to talk with a counsellor or join support groups.

In certain situations, traditional therapies may be excessively taxing on the body and result in debilitating side effects if a patient’s health is rapidly deteriorating. If this is the case, speak with your physician about stopping your medication or switching to palliative care all by yourself.

Quality of life and survival rate for stage 4 lung cancer

As lung cancer advances, it gets worse and is harder to treat. All forms of advanced or metastatic lung cancer often have extremely low survival rates.

Examining the five-year relative survival rate for that particular cancer type is one method of estimating life expectancy when fighting cancer. When comparing a person with a particular type and stage of cancer to those who do not have the disease, a five-year relative survival rate indicates the probability that the person will survive for at least five years following the diagnosis. The life expectancy of patients who have completed therapy and show no signs of illness progression is included in the rate.

According to the American Cancer Society, patients with metastatic (stage 4) non-small cell lung cancer that has progressed to distant organs or body areas have an 8% five-year relative survival rate. Regionally spread stage 4 non-small cell lung cancer has a 37% five-year relative survival rate.

The five-year relative survival rate for small-cell lung cancer that has progressed throughout the body and is metastatic (stage 4) is 3%. The five-year relative survival percentage for patients with stage 4 small cell lung cancer that has metastasized locally is 18%.

It’s crucial to keep in mind that these statistics may not reflect recent advancements in treatment options because they are based on people who had advanced lung cancer at least five years ago. Additionally, the statistics do not account for all the individual characteristics, like the type of cancer and the type of care the patient is receiving.
