Sinonasal undifferentiated carcinoma is a rare and aggressive type of cancer originating in the epithelial layer of the nasal cavity or paranasal sinuses. It was first diagnosed in 1987. The aggressive nature of the cancer coupled with the advanced stage of disease upon presentation lead to a poor survival rate.
Radiation therapy aims to destroy cancer cells by using high energy radiation. [7] Radiation therapy is an effective method for paranasal sinus and nasal cavity cancer after implementation of surgery. [8] Radiation therapy can also be used as an alternative method for a patient who is unable to undergo surgery. [7]
However, the type of chemotherapy that is administered to the patient depends on the type and stage of the cancer. Additionally, chemotherapy can be used as an adjuvant therapy after radiation to lower the risk of recurrence in the patient. If given after radiation, chemotherapy can be used to kill any cancer cells that may have remained. [23]
Improvements in diagnosis and local management, as well as targeted therapy, have led to improvements in quality of life and survival for people with head and neck cancer. [93] After a histologic diagnosis has been established and tumor extent determined, such as with the use of PET-CT, [94] the selection of appropriate treatment for a specific ...
Brain and pancreatic cancers have much lower median survival rates which have not improved as dramatically over the last forty years. [4] Indeed, pancreatic cancer has one of the worst survival rates of all cancers. Small cell lung cancer has a five-year survival rate of 4% according to Cancer Centers of America's Website. [5]
The cell survival curve is a curve often used in radiobiology that represents the relationship between the amount of cells retaining reproductive capabilities and the absorbed dose of radiation from said cells. Tumor cells are able to grow infinitely, while normal cells must undergo treatment in order to grow indefinitely (see Cellular ...
Progression of the disease is defined by the spread of cancer into one or more areas and into deeper tissues. [1] This type of cancer is rare. Only about 2,500 cases are seen in the US each year. [2] Because of this, Hypopharyngeal Cancer is difficult to catch in its earliest stages and has one of the highest mortality rates of any head and ...
This is a very rare neoplasm accounting for approximately 0.0003% of all tumors and about 2.5% of all external ear neoplasms. [3] Ceruminous adenocarcinomas (CA) is a rare type of tumor and has a very small amount of literature on it. The ages to develop ceruminous adenocarcinomas are between 21 and 92 and being most present around 48. [10]
