The carcinoma of unknown primary is defined as histological diagnosis of nodal metastasis without detection of primary tumor. The presentation of cervical metastatic head and neck squamous cell carcinoma (HNSCC) from a clinically occult primary is an unusual event, classically estimated as accounting for less than 5 of all HNSCC.1 The actual rate of unknown primary cancer in any series of HNSCC depends on the The Neck in squamous cell carcinoma (HNSCC) in cancer of unknown primary in skin cancer in salivary gland.IISTE-call for paper www.iiste.org/Journals. Recurrent Head And Neck Cancer Squamous Cell Carcinoma Therapeutics Industry Analysis and Pipeline Review, H2 2014. [Show abstract] [Hide abstract] ABSTRACT: Background The current study was conducted to develop a multifactorial statistical model to predict the specific head and neck (HN) tumor site origin in cases of squamous cell carcinoma confined to the cervical lymph nodes ( unknown primaries). 1. Introduction Squamous cell carcinoma (SCC) of unknown primary site is relatively rare in the head and neck region.

Etiology and risk factors should be considered as for the relevant carcinomas with an identifiable primary site, of the head and neck region i.e. o SCC of mucosal References. Clinical Condition: Adjuvant Therapy for Resected Squamous Cell Carcinoma of the Head and Neck.When PORT is delivered with concurrent chemotherapy, the impact of time to completion of treatment is presently unknown.

SCC of unknown primary represents 3-5 of cancers of head and neck. Likely a result from subclinical primary malignancy in upper aerodigestive tract. Primary identified in approximately 40 of cases (80 of identified primary cancers are from either tonsil or base of tongue). Survival advantages provided by new treatment modalities have been undermined by the significant percentage of people cured of head and neck squamous cell carcinoma (HNSCC) who subsequently develop second primary tumors. Conclusion: The results of our study have shown that IMRT can produce excellent outcomes for patients who present with cervical node squamous cell carcinoma metastases from an unknown head-and-neck primary tumor.

Squamous cell carcinoma (SCC) is the most frequent malignant tumor of the head and neck region.HPV infection is now recognized as one of the primary causes of oropharyngeal SCC (especially SCC of the tonsils and the base of the tongue). Abstract: Background: Squamous cell carcinoma metastatic to the neck from an unknown head and neck primary site is relatively uncommon and presents a challenging diagnostic and therapeutic dilemma. Of these, patients with metastatic carcinoma in the cervical lymph nodes, generally excluding the supraclavicular region without an identifiable primary cancer, are defined as patients who harbor a squamous cell carcinoma of the head and neck of unknown primary origin (SCCHNUP).

Approximately 90 of these neoplasms are squamous cell carcinoma (SCC), with the remainder being adenocarcinoma Squamous cell carcinoma of an unknown primary of the head and neck (SCCUP) is defined as metastatic disease in the lymph nodes of the neck without any evidence of a primary tumor of the mucosa after appropriate investigation.

Most investigators have recommended high-dose radiation therapy as is used to treat squamous cancer of the head and neck, with inclusion of those areas in the head and neck that may harbor an occult primary tumor site.

Squamous cell carcinoma of unknown primary (SCCUP) site metastatic to cervical lymph nodes at presentation is a relatively rare entity forming about 2 of all head and neck carcinomas. Typically patients are treated with ipsilateral modified radical neck dissection (MRND) Head and Neck Squamous Cell Carcinoma of Unknown Primary (SCCUP): Neck Dissection (ND) and Radiotherapy (RT) versus Definitive RT. Additionally, there were fewer patients than anticipated with head and neck squamous cell carcinomas of unknown primary at the time of referral. Hence, these numbers should be interpreted with caution until larger, multicentre studies are conducted. Purpose: To report outcome of patients with head and neck squamous cell carcinoma of unknown primary site (CUP) who had undergone IMRT with selective target volume approach as a part of their overall treatment strategy.
