Prognosis [ edit ] In a meta-analysis of 28 published papers including 158 patients presenting with sinonasal undifferentiated carcinoma with an average of 14 months of follow-up, 25% of patients were alive with no evidence of the disease, 22.4% were alive with presence of the disease, and 52.6% were deceased due to the disease.
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 ...
People with early stage nasal cavity or paranasal sinus cancer often do not show any symptoms, therefore, these types of cancer are usually diagnosed in the later stages. Nasal cavity or paranasal sinus cancer is often discovered when a person is being treated for a seemingly benign, inflammatory disease of the sinuses, such as sinusitis. [4]
Esthesioneuroblastoma can resemble small blue cell tumors like squamous cell carcinoma, sinonasal undifferentiated carcinoma, extranodal NK/T cell lymphoma, nasal type, rhabdomyosarcoma, Ewing/PNET, mucosal malignant melanoma and neuroendocrine carcinomas (NEC) that occur in the intranasal tract.

NUT carcinoma (NC; formerly NUT midline carcinoma (NMC)) is a rare genetically defined, very aggressive squamous cell epithelial cancer that usually arises in the midline of the body and is characterized by a chromosomal rearrangement in the nuclear protein in testis gene (i.e. NUTM1 gene). [2]
Biphenotypic sinonasal sarcoma is a newly recognized, very rare, low-grade malignant tumor of the nasal cavity, which was formerly probably included in fibrosarcoma and synovial sarcoma cases. It was incorporated into the fourth edition of the World Health Organization Classification of Head and Neck Tumours , published in 2017.
Small blue round cells of Ewing Sarcoma Display of small round blue cells characteristic of desmoplastic small round cell tumour.. In histopathology, a small-blue-round-cell tumour (abbreviated SBRCT), also known as a small-round-blue-cell tumor (SRBCT) or a small-round-cell tumour (SRCT), is any one of a group of malignant neoplasms that have a characteristic appearance under the microscope ...
Carcinoma stage is the variable that has been most consistently and tightly linked to the prognosis of the malignancy. Carcinomas are usually staged with Roman numerals. In most classifications, Stage I and Stage II carcinomas are confirmed when the tumor has been found to be small and/or to have spread to local structures only.
