Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat. Check with your doctor if you have a lump or pain in your neck or throat that doesn't go away. These and other signs and symptoms may be caused by metastatic squamous neck cancer with occult primary.
Metastatic squamous cell carcinoma is often referred to as a neck cancer because it tends to travel to the lymph nodes in the neck and around the collarbone. Because of this, signs of metastasis may include a painful or tender lump in the neck or a sore throat that doesn't improve or go away.
Does squamous cell carcinoma spread quickly? One of the factors that can affect a patient's prognosis is whether the malignancy has metastasized (spread to another area of the body). Once squamous cell carcinoma has spread beyond the skin, the five-year survival rate drops to less than 50 percent.
HNSCC can spread (metastasize ) to other parts of the body, such as the lymph nodes or lungs. If it spreads, the cancer has a worse prognosis and can be fatal. About half of affected individuals survive more than five years after diagnosis.

Most (95% to 98%) of squamous cell carcinomas can be cured if they are treated early. Once squamous cell carcinoma has spread beyond the skin, though, less than half of people live five years, even with aggressive treatment. There are many ways to treat squamous cell carcinoma that has not spread.
To metastasize, cancer cells break off from the primary tumor and travel through the blood or lymph to other organs. If someone is found to have cancer in their lymph nodes, it's usually a bad sign that the cancer has or will soon spread to other parts of the body. Most cancer deaths are caused by metastatic cancer.
How head and neck cancer is treated. Many cancers of the head and neck can be cured, especially if they are found early. Although eliminating the cancer is the primary goal of treatment, preserving the function of the nearby nerves, organs, and tissues is also very important.
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 [6].
Dr. Hanke: The first place SCCs metastasize to is the regional lymph nodes. So if you have a squamous cell carcinoma on your cheek, for example, it would metastasize to the nodes in the neck.
Stage 4 squamous cell carcinoma
In stage 4, the cancer can be any size and has spread (metastasized) to one or more lymph nodes which are larger than 3 cm and may have spread to bones or other organs in the body.
The most common sites are the lung (21%), bone (18%), central nervous system (6%) and liver (4%). Distant metastasis is generally associated with a poor prognosis with a 3-year disease-free survival rate in adult transplant patients of 56% (3).
Head and neck cancer symptoms may include a lump in the neck or a sore in the mouth or the throat that does not heal and may be painful, a sore throat that does not go away, difficulty in swallowing, and a change or hoarseness in the voice. These symptoms may also be caused by other, less serious conditions.
Conclusion. In summary, the lung is the most frequent site when patients present with distant metastases after treatment of head and neck cancer with curative intent. Most patients have multiple metastases; in cases of a single metastasis, long-term survival is possible.
The first is direct extension from the primary site to adjacent areas. The second is spread through the lymphatic channels to lymph nodes. The third is spread along nerves (perineural spread) to other areas of the head and neck. The fourth is spread through the blood vessels to distant sites in the body.
"In general, cancers that have spread to the lymph nodes are typically stage 2 or 3," says Juan Santamaria, MD, Nebraska Medicine surgical oncologist. "Many of these cancers are still treatable and even curable at this stage.
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.
Cancer that has spread to the lymph nodes is treatable through surgery, chemotherapy, radiotherapy, and other approaches. However, treatment can never guarantee that cancer will disappear completely or never come back.
Lymph nodes deep in the body cannot be felt or seen. So doctors may use scans or other imaging tests to look for enlarged nodes that are deep in the body. Often, enlarged lymph nodes near a cancer are assumed to contain cancer. The only way to know whether there is cancer in a lymph node is to do a biopsy.
What does a cancerous neck lump feel like? Cancerous lymph nodes can occur anywhere on the neck and are typically described as hard rather than squishy like the swollen nodes caused by infection. The lumps can range in size from a half-inch to several inches in diameter.
Firstline treatment for squamous cell carcinoma of the head and neck is usually TransOral Robotic Surgery (TORS). Radiation therapy and chemotherapy may be used following surgery depending on the diagnosis and stage of cancer. TransOral Robotic Surgery (TORS) offers a minimally invasive surgical option.
