Is oral squamous cell carcinoma aggressive?
OSCC is an aggressive tumor with low response to chemotherapy and basic resistance to most standard-of-care anticancer drugs. 2 The death rate for oral cancer is higher than that of cervical cancer, Hodgkin’s lymphoma, testicular cancer and skin cancer.
Is oral squamous cell carcinoma curable?
It can be cured if found and treated at an early stage (when it’s small and has not spread). A healthcare provider or dentist often finds oral cancer in its early stages because the mouth and lips are easy to exam. The most common type of oral cancer is squamous cell carcinoma.
What are the most common causes of oral squamous cell carcinoma?
The chief risk factors for oral squamous cell carcinoma are heavy smoking and alcohol use. Oral cancer is sometimes asymptomatic initially, so oral screening (typically by dental professionals) is useful for early diagnosis.
Is squamous cell carcinoma and oral cancer same?
Oral cancer includes a group of neoplasms affecting any region of the oral cavity, pharyngeal regions and salivary glands. However, this term tends to be used interchangeably with oral squamous cell carcinoma (OSCC), which represents the most frequent of all oral neoplasms.
What is Stage 2 squamous cell carcinoma?
Stage 2 squamous cell carcinoma: The cancer is larger than 2 centimeters across, and has not spread to nearby organs or lymph nodes, or a tumor of any size with 2 or more high risk features.
How long does squamous cell carcinoma take to metastasize?
Metastasis of cutaneous squamous cell carcinoma (cSCC) is rare. However, certain tumor and patient characteristics increase the risk of metastasis. Prior studies have demonstrated metastasis rates of 3-9%, occurring, on average, one to two years after initial diagnosis .
How long can you live with Stage 4 squamous cell carcinoma?
For a patient with stage IV cancer, age must also be considered to prognose survival. For a patient who is 67 years or older, the expected median survival is a little more than 1 year. If this patient were younger than 67 years, then the expected median survival would be about 2 years.
Why does squamous cell carcinoma keep coming back?
That’s because individuals who were diagnosed and treated for a squamous cell skin lesion have an increased risk of developing a second lesion in the same location or a nearby skin area. Most recurrent lesions develop within two years after the completion of treatment to remove or destroy the initial cancer.
How is oral squamous cell carcinoma diagnosed?
The modern and methodenhanced oral cytology is a simple, value-based and inexpensive tool for early diagnosis of oral squamous cell carcinoma and its precursor lesions. Surgical biopsy and histopathological examination remains the gold standard for definitive diagnosis.
What is the best treatment for oral squamous cell carcinoma?
Treatment of Oral Squamous Cell Carcinoma
For most oral cavity cancers, surgery is the initial treatment of choice. Radiation or chemoradiation is added postoperatively if disease is more advanced or has high-risk features.
What areas of the mouth are the most common sites for squamous cell carcinoma?
Site distribution showed that the most common location of the tumors was the border of the tongue (37%), followed by the alveolar mucosa and gingiva (20%) and floor of the mouth and ventral tongue (19%).
Why should you be concerned about squamous cell carcinoma?
Untreated squamous cell carcinoma of the skin can destroy nearby healthy tissue, spread to the lymph nodes or other organs, and may be fatal, although this is uncommon. The risk of aggressive squamous cell carcinoma of the skin may be increased in cases where the cancer: Is particularly large or deep.
