Squamous Cell Carcinoma Invasive Type
Squamous Cell Carcinoma Invasive Type invasive squamous cell carcinoma is a type of cancer that occurs in the fat cells that form the outer layer of the skin and the lining of some organs known as squamous cell carcinomas. In this case, the word invasive means that the cancerous tumor has penetrated deep into the skin or organ, rather than remaining a surface lesion. For example, in cases of invasive squamous cell carcinoma of the skin, the tumor may have penetrated through the epidermis into the dermis. Depending on the location, size, and severity of the tumor, there are different treatment methods.
Squamous cell carcinoma is the second most common form of skin cancer after basal cell carcinoma. It is usually caused by UV rays, either by natural sunlight or by tanning indoors. People with light skin are particularly vulnerable. It can also occur in organs as diverse as the prostate, bladder, and larynx, although these are far from as common as squamous cell carcinomas. Exposure to radiation or chemical carcinogens, as well as some inflammatory or scarring disorders, can also increase the risk of squamous cell carcinoma.
Invasive squamous cell carcinoma can be severe due to the risk of cancer metastasis, which means that cancer spreads to other parts of the body or additional organ systems. This risk of metastasis is higher for invasive lesions than for shallow lesions. The risk increases when the tumor is large, very deep or close to other systems such as lymph nodes or nerves. Some patient characteristics can also affect this risk, such as a malfunction of the immune system.

Most often, this condition is treated by surgical removal of the tumor, which is normally curative. A special surgical technique called Mohs surgery, which precisely determines the boundaries of a tumor, can be used for irregularly formed or possibly disfigured lesions. If a tumor is classified as high-risk due to its location, depth, size, or tumor characteristics, radiotherapy may be required to ensure that all cancer is removed or destroyed. Chemotherapy may be required if the cancer is metastatic, but this treatment is unlikely if the tumor has spread.
Squamous Cell Carcinoma Invasive Type
Patients with invasive squamous cell carcinoma have a higher risk of developing others. It is important to closely monitor skin changes and avoid unprotected sunlight. Regular visits to a dermatologist for a complete skin examination also help to quickly detect future tumors, which facilitates treatment and increases the likelihood that it will be successful.
Unlike its more common non-invasive form, the skin’s invasive squamous cell carcinoma (SCC) can be biologically aggressive and prone to recurrence. The aim of this study was to identify relevant clinical-pathological prognosis factors associated with the results of patients with invasive SCC to define a high-risk group.
Retrospectively, we reviewed the records of patients with invasive cutaneous SCC of the torso or extremities who have undergone surgery at a tertiary cancer center over the past 10 years. We examined the presentation patterns, all known clinical and histological risk factors for recurrence and their association with survival.
136 patients were identified, of which 102 (74%) were male. Presentation patterns included primary (n = 91), locally recurring (n = 16), regional (n = 24) and distant (n = 5) diseases. Univariate analyses revealed poorly differentiated carcinomas (hazard ratio [HR] = 2.92, P = 0.016), scar cancers (HR = 3.12, P = 0.008), tumor sizes> 2 cm (HR = 3.79, P = 0.006). and regional node disease (HR = 5.77, P .0001) as significant risk factors for recurrence or death. However, in multivariate analysis, only one regional node disease was found to be significant at the time of presentation (HR = 7.64, P .0001).
Patients with invasive SCCs metastarating to regional nodes are a group at high risk of recurrence and death. Such patients should be considered for adjuvant therapy studies.
