Survival rates for treated esthesioneuroblastoma are best for surgery with radiotherapy (65%), then for radiotherapy and chemotherapy (51%), just surgery (48%), surgery, radiotherapy and chemotherapy (47%) and finally just radiotherapy (37%). [14] From the literature, radiotherapy and surgery seem to boast the best outcome for patients.
Ceruminous adenocarcinoma is a malignant neoplasm derived from ceruminous glands of the external auditory canal.This tumor is rare, with several names used in the past. [3] [4] Synonyms have included cylindroma, ceruminoma, ceruminous adenocarcinoma, not otherwise specified (NOS), ceruminous adenoid cystic carcinoma (ACC), [1] [2] and ceruminous mucoepidermoid carcinoma.
The CyberKnife radiation system introduced in 1994 recommends a protocol of three sessions known as hypofractionation. Radiation dosages overall were reduced over the years as experience showed that excellent tumor control rates could be maintained even as dosages were lowered to benefit hearing preservation and facial nerve function.
Cancer in the head or neck may impact a person's mental well-being and can sometimes lead to social isolation. [113] This largely results from a decreased ability or inability to eat, speak, or effectively communicate. Physical appearance is often altered by the cancer itself and/or as a consequence of treatment side effects.
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]
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 reported health effects are consistent with high doses of radiation, and comparable to the experiences of cancer patients undergoing radio-therapy [15] but have many other potential causes. [14] The effects included "metallic taste, erythema, nausea, vomiting, diarrhea, hair loss, deaths of pets, farm and wild animals, and damage to plants."
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.
