What is Lung Squamous Cell Carcinoma?

Lung squamous cell carcinoma, also known as epidermoid carcinoma, is a type of non-small-cell lung cancer that originates in the thin, flat cells lining the airways. It accounts for about 30% of all lung cancers [2].

Characteristics and Types

This form of lung cancer typically develops in one of the air passages in the lungs and begins in the tissues that line these air passages [6]. There are two types of lung cancer: small lung cell carcinoma, which includes squamous cell carcinoma, and non-small cell lung cancer, with subtypes being adenocarcinoma and large cell carcinoma.

Symptoms

Early on, squamous cell lung cancer may have no symptoms. If symptoms occur, they may include coughing, chest pain, weight loss, and fatigue [7]. If the cancer has spread beyond the lungs, it can cause additional symptoms such as difficulty swallowing or shortness of breath.

Prevalence and Statistics

Squamous cell carcinoma of the lung is a significant type of non-small-cell lung cancer. It's worth noting that about 85% of all lung cancers are classified as non-small-cell lung cancer [1].

Common Signs and Symptoms of Lung Squamous Cell Carcinoma

Lung squamous cell carcinoma, also known as squamous cell carcinoma of the lung, is a type of non-small cell lung cancer that accounts for about 30% of all lung cancers. The symptoms of this disease can vary from person to person, but there are some common signs and symptoms that are often associated with it.

Common Symptoms:

• Cough: A persistent cough that doesn't go away is one of the most common symptoms of lung squamous cell carcinoma [1].
• Shortness of Breath: Shortness of breath or wheezing can also be a symptom of this disease, especially if the cancer has spread to other parts of the body [2].
• Hoarseness: Hoarseness or a change in voice tone can be another sign of lung squamous cell carcinoma [3].
• Chest Pain: Chest pain or discomfort can also occur due to the growth of the tumor in the lungs [4].

Other Possible Symptoms:

• Fatigue: Feeling extremely tired or weak is a common symptom of many types of cancer, including lung squamous cell carcinoma [5].
• Weight Loss: Unexplained weight loss can be another sign of this disease [6].
• Bone Pain: Bone pain or numbness in the limbs can occur if the cancer has spread to the bones [7].

Important Note:

It's essential to note that these symptoms can also be caused by other conditions, such as bronchitis, pneumonia, or emphysema. If you're experiencing any of these symptoms, it's crucial to consult a doctor for proper diagnosis and treatment.

Diagnostic Tests for Lung Squamous Cell Carcinoma

Lung squamous cell carcinoma (SqCC) is a type of non-small-cell lung cancer that originates in the thin, flat cells lining the airways [7]. Diagnosing this condition requires a combination of imaging tests and laboratory examinations. Here are some diagnostic tests used to detect lung SqCC:

• Imaging Tests: Computed tomography (CT) scans, magnetic resonance imaging (MRI), positron emission tomography (PET) scans, X-rays, and ultrasound are commonly used to visualize the lungs and surrounding tissues [4][5].
• Laboratory Tests: Blood tests, including a complete blood count (CBC), can provide information on a patient's overall health and help identify any potential biomarkers for lung cancer [6]. A "liquid biopsy" or blood test may also be performed to rapidly identify several types of important biomarkers [8].
• Biopsies: A tissue biopsy is the only way to confirm a diagnosis of lung cancer, including SqCC. This involves removing a small sample of tissue from the lungs for examination under a microscope.
• Other Tests: Mediastinoscopy and mediastinotomy may be performed to examine the lymph nodes in the chest cavity [1]. Endobronchial ultrasound, endoscopic esophageal ultrasound, bronchoscopy, and other tests may also be used to stage the cancer or assess its spread.

These diagnostic tests can help identify lung SqCC and determine the best course of treatment. However, it's essential to note that a combination of these tests is often necessary to confirm a diagnosis and develop an effective treatment plan.

Lung squamous cell carcinoma (LSCC) is a type of non-small cell lung cancer (NSCLC) that typically requires a combination of therapies for treatment.

Treatment Options

According to recent studies, the following drug treatments have been approved or investigated for LSCC:

• Platinum-based chemotherapy: This is often used as a first-line treatment for LSCC. Platinum-based regimens such as cisplatin and carboplatin have shown efficacy in treating this type of cancer [4].
• Targeted therapy: Targeted therapies, such as ramucirumab, have been investigated in combination with chemotherapy for the treatment of LSCC [5]. These treatments aim to specifically target cancer cells while minimizing harm to healthy cells.
• Immunotherapy: Immunotherapies, including checkpoint inhibitors, have shown promise in treating NSCLC, including LSCC. However, more research is needed to fully understand their efficacy and potential side effects [2].

Other Treatment Options

In addition to drug treatments, other options may be considered for patients with LSCC:

• Surgery: Early-stage LSCC can often be treated with surgery alone [3].
• Radiation therapy: This may be used in combination with chemotherapy or as a standalone treatment for more advanced cases of LSCC [6].

Current Research and Recommendations

It's essential to note that the most effective treatment approach will depend on individual patient factors, such as overall health and cancer stage. As research continues to evolve, it's crucial to consult with a healthcare professional to determine the best course of action for each patient.

Differential Diagnosis of Lung Squamous Cell Carcinoma

Lung squamous cell carcinoma (SqCC) is a type of non-small cell lung cancer (NSCLC) that can be challenging to diagnose due to its similarity in appearance with other epithelioid neoplasms. The differential diagnosis of primary squamous cell carcinomas of the lung includes secondary carcinomas with squamous differentiation and other epithelioid tumors.

Key Differentials:

• Secondary Carcinomas: These are metastatic lesions from head and neck squamous cell carcinoma, which can be differentiated using immunohistochemical analysis (IHC) for markers such as KRT13 and UPK1B [8].
• Solid Pattern Adenocarcinoma: This type of adenocarcinoma lacks diffuse p40 or p63 expression on IHC, distinguishing it from SqCC [6].
• High Grade Small Cell Carcinoma: Typically presents with a more aggressive clinical course and can be differentiated based on the presence of neuroendocrine markers [6].

Clinical Characteristics:

SqCC is usually more aggressive than NSCLC and presents as a central lesion with hilar and mediastinal invasion along with regional adenopathy [2]. The differential diagnosis depends on the location and appearance of the mass, with generic differentials for individuals presenting with chronic cough, weight loss, hemoptysis, and dyspnea [3].

Diagnostic Criteria:

A new diagnostic criteria using clinical characteristics and IHC results has been suggested to improve the accuracy of SqCC diagnosis [9]. However, there are two underlying assumptions that need to be considered when applying these criteria.
