Squamous cell carcinoma (SCC) is a cancer that develops from squamous cells, which form the surface of the skin and line several organs and tissues.

SCC can differ considerably according to its anatomical origin, molecular characteristics, stage, and treatment response.

Therefore, researchers require well-characterized human biospecimens to investigate tumor biology, biomarkers, disease progression, and therapeutic approaches.

At Bay Biosciences, we understand this need and provide high-quality squamous cell carcinoma tissue samples and other human biospecimens for research and development purposes.

Understanding Squamous Cell Carcinoma

Squamous cell carcinoma develops when squamous cells acquire abnormal changes that cause uncontrolled growth and the formation of malignant tumors.

The characteristics of SCC vary according to the tissue in which the cancer originates.

Head and neck squamous cell carcinoma (HNSCC) develops in squamous cells lining areas such as the mouth, throat, larynx, nasal cavity, and other parts of the head and neck.

Lung squamous cell carcinoma is a histological subtype of non-small cell lung cancer (NSCLC). It commonly develops in the airways and has a strong association with tobacco smoking.

Cutaneous squamous cell carcinoma (cSCC) begins in squamous cells of the epidermis and commonly develops on areas exposed to sunlight, including the face, ears, neck, lips, and hands.

These differences make tissue-specific and clinically annotated specimens important for SCC research.

Squamous Cell Carcinoma Samples

Symptoms of Squamous Cell Carcinoma

Symptoms vary depending on where the tumor develops.

Patients with head and neck squamous cell carcinoma may experience:

Symptoms of lung squamous cell carcinoma may include:

On the other hand, cutaneous SCC may appear as a firm red bump, scaly patch, open sore, or wart-like growth that may crust or bleed.

These lesions frequently occur on sun-exposed areas of the skin.

Causes & Risk Factors of Squamous Cell Carcinoma

The causes of SCC depend partly on its anatomical location.

Firstly, for head and neck cancers, tobacco use, heavy alcohol consumption, and certain high-risk HPV infections are important risk factors. HPV is particularly associated with cancers of the oropharynx.

Secondly, for lung SCC, cigarette smoking is a major risk factor. Other exposures, including secondhand smoke, air pollution, asbestos, and occupational carcinogens, may also contribute to lung cancer development.

Thirdly, for cutaneous SCC, prolonged exposure to ultraviolet radiation is the major known environmental risk factor.

Moreover, chronic skin inflammation, immunosuppression, previous radiation exposure, arsenic exposure, and certain genetic conditions may also increase risk.

Diagnosis of Squamous Cell Carcinoma

Diagnosis depends on the anatomical site and suspected tumor type.

Firstly, physicians review the patient’s medical history, symptoms, and relevant risk factors and perform a physical examination.

Secondly, imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), or other site-specific imaging methods may be used to identify tumors and evaluate their extent.

Thirdly, a biopsy  is also important for the diagnosis of SCC.

Finally, additional testing may assess biomarkers, genetic alterations, HPV status, immune markers, or other molecular characteristics.

These analyses can help classify tumors and support research into targeted and immune-based treatment strategies.

Treatment of Squamous Cell Carcinoma

Treatment depends on the anatomical location, stage, tumor characteristics, and overall health of the patient.

For localized cutaneous SCC, treatment may include surgical excision, Mohs micrographic surgery, radiation therapy, curettage and electrodesiccation, or other site-specific approaches.

Treatment for head and neck SCC may include surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, or combinations of these approaches.

For lung SCC, treatment can include surgery for selected early-stage tumors, radiation therapy, chemotherapy, immunotherapy, and targeted approaches when appropriate.

Researchers continue to evaluate new treatment combinations and personalized approaches using patient-derived biospecimens.

Applications of Squamous Cell Carcinoma Tissue Samples for Research

Head and Neck Squamous Cell Carcinoma Samples

Head and neck squamous cell carcinoma samples supports research into tumor biology, HPV-associated disease, molecular alterations, immune responses, biomarkers, treatment resistance, and therapeutic development.

Lung Squamous Cell Carcinoma Tissue Samples

Lung squamous cell carcinoma tissue samples can be used to investigate tumor morphology, genomic alterations, signaling pathways, biomarker expression, disease progression, and treatment response.

Skin Squamous Cell Carcinoma Biospecimens

Skin squamous cell carcinoma biospecimens can support studies of cutaneous tumor development, ultraviolet-associated molecular changes, immune responses, biomarkers, and mechanisms of treatment resistance.

Squamous Cell Carcinoma FFPE Samples

Squamous cell carcinoma FFPE samples provide preserved tissue suitable for histopathology, immunohistochemistry, biomarker analysis, and selected molecular studies.

Lung SCC Biospecimens for Research

Lung SCC biospecimens for research may include tumor tissue, serum, plasma, PBMCs, and other patient-derived materials. Combining different specimen types can help researchers investigate tumor-associated biomarkers, immune responses, molecular characteristics, and treatment-related changes.

Cutaneous SCC Tissue Samples

Cutaneous SCC tissue samples can support investigations into tumor progression, cellular differentiation, genomic alterations, immune-cell infiltration, and biomarkers associated with disease behavior. These specimens can also be used in research evaluating emerging treatment strategies.

Frequently Asked Questions

What are squamous cell carcinoma tissue samples?
