lung sarcoma
Description
What is Lung Sarcoma?
Lung sarcoma, also known as pulmonary sarcoma, is a rare and aggressive type of cancer that develops in the supportive tissue or blood vessels in the lungs [10]. It is a type of soft tissue sarcoma, which means it originates from the soft tissues surrounding other body structures, such as muscles, fat, blood vessels, nerves, tendons, and the lining of joints [9].
Types of Lung Sarcoma
Lung sarcomas are rare and can be classified into different subtypes. Some common types include:
- Pulmonary sarcomatoid carcinoma (PSC): a highly invasive and biphasic type of pulmonary cancer with a poor prognosis [13].
- Carcinoid tumors: account for fewer than 5% of lung tumors, most of which grow slowly [5].
Characteristics
Lung sarcoma is characterized by its rapid growth and potential to spread to other parts of the body. It can cause symptoms such as chest pain or discomfort, a persistent cough, and coughing up blood [8]. The risk factors for developing lung sarcoma include smoking, which increases the risk of lung cancer in general.
Prevalence
Lung sarcoma is an extremely rare type of cancer, accounting for less than 0.5% of all lung tumors [6]. It is often misdiagnosed as other types of lung cancer or conditions due to its rarity and similar symptoms.
Treatment and Outlook
The treatment options for lung sarcoma depend on the stage and subtype of the cancer. Surgery, chemotherapy, and radiation therapy may be used in combination to treat this aggressive type of cancer [10]. Unfortunately, the prognosis for patients with lung sarcoma is generally poor due to its rapid growth and potential to spread

Signs and Symptoms
Lung sarcoma, also known as pulmonary sarcoma, is a rare type of cancer that develops in the supportive tissue or blood vessels in your lungs. The signs and symptoms of lung sarcoma can be similar to those of other types of lung cancer, but may also include:
- A lump or mass in the chest that can be felt through the skin
- Chest pain or discomfort
- Coughing up blood or rust-colored sputum
- Shortness of breath or difficulty breathing
- Weight loss or loss of appetite
- Fatigue or feeling weak
It's worth noting that lung sarcoma is a rare type of cancer, and its symptoms may not always be immediately apparent. If you are experiencing any of these symptoms, it's essential to consult with your healthcare provider for proper evaluation and diagnosis.
According to [10], the most common signs and symptoms of lung sarcoma include a lump or mass in the chest that can be felt through the skin, chest pain or discomfort, coughing up blood or rust-colored sputum, shortness of breath or difficulty breathing, weight loss or loss of appetite, and fatigue or feeling weak.
Additionally, [11] states that early detection is key to diagnosing and treating sarcoma. The four qualities that can help determine whether a new or existing lump is potentially a sarcoma include location (most sarcomas develop in the arms and legs), size (sarcomas are often larger than 2 cm), texture (sarcomas may feel hard, firm, or irregular), and growth rate (sarcomas tend to grow rapidly).
It's also important to note that lung sarcoma can be difficult to diagnose because it can be confused with other conditions that have similar symptoms. [12] states that blood tests won't show sarcoma, but they can show signs of illness or disease including cancer. A skin exam and imaging tests may also be used to evaluate the presence of sarcoma.
According to [13], sarcoma affects both children and adults, and generally, soft tissue sarcoma occurs more frequently in adults. Bone sarcoma diagnoses occur more often in children, teens, and people older than 65 years.
Additional Symptoms
- Chest pain or discomfort
- Shortness of breath or difficulty breathing
- Weight loss or loss of appetite
- A lump or mass in the chest that can be felt through the skin
- Coughing up blood or rust-colored sputum
- Fatigue or feeling weak
Diagnostic Tests
Diagnostic Tests for Lung Sarcoma
Lung sarcoma, also known as pulmonary sarcoma, is a rare type of cancer that develops in the supportive tissue or blood vessels in your lungs. Diagnosing lung sarcoma can be challenging, but various tests and procedures can help confirm the presence of this condition.
- Imaging Tests: Imaging tests such as CT scans, MRI, and PET scans are often used to diagnose lung sarcoma. These tests create detailed images of the inside of your body, helping doctors to identify any abnormalities in the lungs.
- A CT scan uses x-rays to make detailed cross-sectional images of your body [11].
- An MRI can provide more detailed images of soft tissue and organs, including the lungs [10].
- Biopsy: The only way to be certain a tumor is soft tissue sarcoma, including lung sarcoma, is through a biopsy. A biopsy involves removing a small number of cells from the tumor to examine under a microscope.
- If the test shows that the tumor may be a sarcoma, another type of biopsy probably will be done to remove more cells for examination [13].
- Blood Tests: Blood tests such as complete blood count (CBC) and blood chemistry tests can also help diagnose lung sarcoma. These tests can detect any abnormalities in your blood cells or chemistry.
- A CBC blood test looks at a number of different types of blood cells, which can be affected by cancer [9].
- Other Tests: Other tests such as pulmonary function tests (PFTs) and sputum cytology may also be used to diagnose lung sarcoma. These tests can help assess how well your lungs are functioning and detect any abnormal cells in your sputum.
- A PFT is a breathing test that measures how well your lungs are working [6].
- Sputum cytology involves examining the cells in your sputum under a microscope to look for cancerous cells [8].
It's essential to note that diagnosing lung sarcoma can be complex, and a combination of these tests may be used to confirm the presence of this condition.
Treatment
Treatment Options for Lung Sarcoma
Lung sarcoma, also known as pulmonary sarcoma, is a rare and aggressive type of cancer that originates in the lungs. While it's not as common as other types of lung cancer, treatment options are available to manage this condition.
Chemotherapy
Chemotherapy is a standard treatment approach for lung sarcoma. It involves using medications to kill cancer cells or slow their growth. Chemotherapy can be used alone or in combination with other treatments such as targeted therapy and immunotherapy [1].
Targeted Therapy
Targeted therapies, also known as precision medicines, are designed to target specific weaknesses in cancer cells. For lung sarcoma, targeted therapies like alectinib, osimertinib, and nivolumab have shown promise in clinical trials [2][3]. These medications can help reduce tumor size and improve survival rates.
Immunotherapy
Immunotherapies work by stimulating the immune system to attack cancer cells. For lung sarcoma, immunotherapies like atezolizumab (Tecentriq) have been approved for use in combination with chemotherapy [4].
Other Treatment Options
In addition to chemotherapy, targeted therapy, and immunotherapy, other treatment options may be considered on a case-by-case basis. These can include radiation therapy, surgery, or a combination of these approaches.

Differential Diagnosis
Differential Diagnosis of Lung Sarcoma
Lung sarcoma, also known as pulmonary sarcoma, is a rare and aggressive type of cancer that originates in the lungs. The differential diagnosis of lung sarcoma involves identifying other conditions that may present with similar symptoms or imaging findings.
Common Differential Diagnoses:
- Metastatic carcinoma: Lung sarcoma must be differentiated from metastatic carcinoma, which can also present as a pulmonary mass.
- Pulmonary embolism: Pulmonary sarcoma can mimic the appearance of a pulmonary embolism on imaging studies.
- Lymphoma: Lymphoma can also present as a pulmonary mass and may require differentiation from lung sarcoma.
- Thyroid cancer: Thyroid cancer can metastasize to the lungs and may be considered in the differential diagnosis of lung sarcoma.
Other Conditions to Consider:
- Pulmonary nodules: Multiple pulmonary nodules, such as those seen in cannonball appearance, can be associated with various conditions including colorectal cancer, ovarian cancer, and thyroid cancer.
- Pleural effusion: Pleural effusion can be a complication of lung sarcoma or other conditions such as bacterial pneumonia, bronchitis, or mycoplasmal pneumonia.
Key Points to Consider:
- Imaging studies: Imaging studies, such as CT scans or MRI, are essential in the differential diagnosis of lung sarcoma.
- Clinical history: A thorough clinical history is crucial in differentiating lung sarcoma from other conditions.
- Pathological examination: Pathological examination of tissue samples can help confirm the diagnosis of lung sarcoma.

- [3] The differential diagnosis of lung tumors would cover nearly all the diseases of the respiratory tract, and therefore, the scope of this contribution must be arbitrarily limited at the outset.
- [8] Primary pulmonary synovial sarcoma (PPSS) is a rare malignancy that represents less than 0.5% of malignant pulmonary neoplasms and 10% of primary pulmonary tumors.
- [11] The differential diagnosis for pulmonary synovial sarcoma is broad and includes a variety of spindle cell neoplasms, including metastatic synovial sarcoma from non-thoracic primaries.
