Status of Government-Funded Radiotherapy Services in Nigeria.

PURPOSE: Access to radiotherapy (RT) is now one of the stark examples of global cancer inequities. More than 800,000 new cancer cases require potentially curative or palliative RT services in Africa, arguably <15% of these patients currently have access to this important service. For a population of more than 206 million, Nigeria requires a minimum of 280 RT machines for the increasing number of cancer cases. Painfully, the country has only eight Government-funded RT machines. This study aimed to evaluate the status of the eight Government-funded RT services in Nigeria and their ability to deliver effective RT to their patients. METHODS: A survey addressing 10 critical areas was used to assess the eight Government-funded RT services in Nigeria. RESULTS: Unfortunately, six of the eight centers (75%) surveyed have not treated patients with RT because they do not have functioning teletherapy machines in 2021. Only two RT centers have the capability of treating patients using advanced RT techniques. There is no positron emission tomography-computed tomography scan in any of the Government-funded RT centers. The workforce capacity and infrastructure across the eight centers are limited. All of the centers lack residency training programs for medical physicists and radiation therapy technologists resulting in very few well-trained staff. CONCLUSION: As the Nigerian Government plans for the new National Cancer Control Plan, there is an urgent need to scale up access to RT by upgrading the RT equipment, workforce, and infrastructure to meet the current needs of Nigerian patients with cancer. Although the shortfall is apparent from a variety of RT-capacity databases, this detailed analysis provides essential information for an implementation plan involving solutions from within Nigeria and with global partners.

Histolopathological Patterns of Cervical Carcinoma Seen at A Radiotherapy Centre in Ibadan, Nigeria.

INTRODUCTION: The treatment of cervical carcinoma is dependent on many factors including histological types and degree of differentiation. Degree of differentiation is an important consideration in determining the prognostic outcome. OBJECTIVE: The study is to describe the histological pattern of cervicer cancer seen in our practice with emphasis on tumour differentiation. METHOD: This retrospective study was carried out within Radiotherapy Department of University College Hospital, Ibadan. The records of patients diagnosed of cervical cancer seen between July 2008 and June 2010 were analysed. Data pulled out included age, disease stage at presentation, histological variant and degree of differentiation. RESULTS: 206 patients were seen during the period of which 196 had complete data. Squamous cell carcinoma (SCC) was seen in 178 patients (i.e. 90.8%) while 14 patients (7.1%) had adenocarcinoma. One patient each had adenoid cystic carcinoma, adenosquamous carcinoma, clear cell carcinoma and mucinous carcinoma. Majority of the patients, 99 (50.5%) had poorly differentiated tumours, 64 (32.7%) had well differentiated tumours, while the rest 33 (16.8%) had moderately differentiated tumours. Of the SCC tumours, 95 (53.4%) were poorly differentiated, 58 (32.6%) well differentiated while the remaining 25 (14%) were moderately differentiated. In comparison only 3 of the 14 adenocarcinoma cases (21.4%) were poorly differentiated, 5 cases (35.7%) were well differentiated, while 6 (42.9%) were moderately differentiated. The difference in the degree of differentiation between squamous histology and adenocarcinoma was statistically significant (p value = 0.002). CONCLUSION: Poorly differentiated squamous cell carcinoma remains the leading variants of cervical cancer seen in our environment.

Evaluation of humoral immunity in oral cancer patients from a nigerian referral centre.

The immune system is central in the body's defense against non-self. Immunoglobulins and acute phase proteins have been reported to play active roles in carcinogenesis. This prospective longitudinal study was carried out to determine the state of humoral immunity in Nigerian oral cancer patients relative to controls. Twenty newly diagnosed untreated cases of oral squamous cell carcinoma recruited from our centre were included in the study. The controls included 20 apparently healthy and HIV negative volunteers. Serum immunoglobulin classes and acute phase proteins were measured using immunoplates. IgA and ceruloplasmin showed statistically significantly elevated levels in the patients compared with controls, while increases in IgM and IgG were insignificant. The raised levels suggest a role for immunoglobulin A and ceruloplasmin in the mechanisms involved in oral cancers. Findings from this study are similar to that reported elsewhere in the literature. Further work is needed to ascertain the role and usefulness of immunoglobulins and acute phase proteins in staging, disease monitoring, therapy and prognostication.

Histolopathological patterns of cervical carcinoma seen at a radiotherapy centre in Ibadan, Nigeria.

BACKGROUND: The treatment of cervical carcinoma is dependent on many factors including histological types and degree of differentiation. Degree of differentiation is an important consideration in determining the prognostic outcome.

The records of patients diagnosed of cervical cancer seen between July 2008 and June 2010 were analysed. Data pulled out included age, disease stage at presentation, histological variant and degree of differentiation. RESULTS: 206 patients were seen during the period of which 196 had complete data.
