Which lymph nodes does nasopharyngeal cancer spread to?
Like most other squamous cell carcinomas (SCC) of the head and neck primaries, lymphatic drainage of the nasopharynx is predominantly to the cervical lymph nodes. However, NPC has the highest preponderance for regional lymph node metastasis among head and neck SCC .
How quickly does nasopharyngeal cancer progress?
The median growth rate was 1.63mm(3) per day and the median tumor doubling time was 279days. This study is the first report in the literature looking at the natural progression of nasopharyngeal carcinoma (NPC) based on clinical information.
What is a common site of metastasis for nasopharyngeal carcinoma?
The incidence of bone metastasis is approximately 64%-67%, and bone is the most common site of metastases in NPC. In addition, because the nasopharynx is adjacent to a rich lymphatic network, poorly differentiated and undifferentiated NPCs are more likely to metastasize than other head and neck squamous cancers.
Is Stage 3 nasopharyngeal cancer curable?
The 5-year disease-specific survival rate for the 173 patients was 32.3%, and the 5-year disease-specific survival rates for the groups of patients according to their stages were 100% for stage I, 85.7% for stage IIa, 54.5% for stage IIb, 30.4% for stage III, 25.0% for stage IVa, and 25.0% for stage IVb.
Is nasopharyngeal cancer painful?
Most people with nasopharyngeal cancer (NPC) notice a lump or mass in the neck that leads them to see a doctor. There may be lumps on both sides of the neck towards the back. The lumps are usually not tender or painful.
How long can I live with stage 4 nasopharyngeal cancer?
The results showed that the patients with stage I, II nasopharyngeal carcinoma and those with stage III, IV, the 10-year survival rates were 41.5% and 22.8% respectively, the overall 10-year survival rate being 27.3%.
How serious is nasopharyngeal cancer?
If the cancer is located only in the nasopharynx, the 5-year survival rate is 85%. If the cancer has spread to nearby tissues or organs and/or regional lymph nodes, the 5-year survival rate is 71%. If there is distant spread to other parts of the body, the 5-year survival rate is 49%.
Is nasopharyngeal cancer common?
Nasopharyngeal cancer (NPC) is quite rare. In most parts of the world (including the United States), there’s less than one case for every 100,000 people each year. This cancer is much more common in certain parts of South Asia, the Middle East, and North Africa.
Does brain MRI show nasopharynx?
MRI is able to distinguish between a primary tumor confined to the nasopharynx that is only bulging into the fat space (stage T1), a primary tumor confined to the nasopharynx which is abutting a metastatic retropharyngeal node (stage T1N1), and a primary tumor that is directly invading the parapharyngeal region (stage …
