Insights

Childhood cancer incidence in Namibia is lower than in developed nations, with central nervous system tumours being most common. Cancer rates show a mix of African and industrialised country patterns.

Area of Science:

  • Paediatric Oncology
  • Epidemiology
  • Global Health

Background:

  • Childhood cancer presents a significant global health challenge, with varying incidence and patterns across different regions.
  • Understanding the epidemiology of paediatric malignancies is crucial for resource allocation and targeted interventions.

Purpose of the Study:

  • To determine the incidence and frequency of paediatric malignancies in Namibia.
  • To compare these findings with established childhood cancer rates in other countries.

Main Methods:

  • A retrospective descriptive study was conducted using a 6-year survey of childhood cancer data in Namibia (1983-1988).
  • Incidence and frequency rates were calculated for 163 children under 15 years diagnosed with malignant neoplasms, intracranial tumours, or histiocytosis.

Main Results:

  • The overall childhood cancer incidence in Namibia was 55.5 per million children.
  • Central nervous system tumours were the most frequent (18%), followed by renal tumours (14%), leukaemia (12%), and lymphoma (11.5%).
  • Incidence rates for retinoblastoma, renal tumours, bone tumours, and soft-tissue sarcomas showed similarities to rates in other African countries or Western nations, while leukaemia and lymphoma rates were lower than in central Africa or developed countries.

Conclusions:

  • The incidence patterns of childhood cancer in Namibia exhibit characteristics of both African and industrialised country profiles.
  • These findings highlight the unique epidemiological landscape of paediatric malignancies in sub-Saharan Africa.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
Cancer Survival Analysis01:21

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
