Abstract Objective: Data was collected to evaluate the survival rates of head and neck (conjunctiva, oropharyngeal and nonoropharyngeal) squamous cell carcinomas in Ghana. Data description: We provided data on a retrospective review of 8 years (January 2004 to December 2009) survival rate of head and neck squamous cell carcinomas (HNSCCs) at the Komfo Anokye Teaching Hospital in Ghana. The data consist of patient demographic data and clinicopathological findings which includes tumour site, tumour stage and histological grades of the patients. Clinical outcome measurement was death through to January 2013 on record and confirmed from the hospitals birth and death registry department. More than 85% of death cases were confirmed by gender, age, and folder identification numbers from the birth and death registry. Keywords: HNSCCs, Survival period, Conjunctiva, Oropharyngeal Objective Head and neck squamous cell carcinomas (HNSCCs) are heterogeneous tumours that develop in the oral cavity, oropharynx, hypopharynx, and larynx [1]. The incidence of HNSCCs vary broadly in Africa [2, 3] compared with that in western societies [4] largely because of wide variation in population size, economic status, ethnic origin, and belief in traditional medicine existing in Africa [5]. In Ghana, tumors of the pharynx and larynx represents 7.4% and 3.5% of all malignancies, and the second and seventh most common types of cancers, respectively seen at the National Hospital [6]. Also, data existing at the Komfo Anokye Teaching Hospital (KATH) indicate that tumors of the pharynx, larynx and oral cavity formed the
largest group of HNSCCs, and most patients’ presents with late-stage disease [7, 8]. Despite recent advances in the diagnosis and treatment of head and neck cancer, there has been little evidence of improvement in survival rates over the last few decades [9]. Independent of the numerous reports on the epidemiology and molecular characteristics of HNSCCs in Ghana, there is a dearth of data on the survival rate of patients. The first attempt at population-based cancer registration was set up in 2012 however, it would take a few years to generate survival data. Identifying the need for survival analysis, we retrospectively compiled data on HNSCCs from the pathological perspective at KATH in Ghana over a period of 8 years.
