Abstract
Objective: Cervical cancer is the second most prevalent cancer in females worldwide. Infection with human papillomavirus (HPV) is regarded as the main risk factor of cervical cancer. One objective of this study was to conduct a qualitative systematic review of some case-control studies and to examine the role of human papillomavirus (HPV) in the development of human cervical cancer (CC) beyond any reasonable doubt. Methods: We conducted a systematic review and re-analysis of some impressive key studies aimed to answer the following question. Is there a cause-effect relationship between human papillomavirus and cervical cancer? The method of the conditio sine qua non relationship was used to proof the hypothesis whether the presence of human papillomavirus guarantees the presence of cervical carcinoma. In other words, if human cervical cancer is present, then human papillomavirus is present too. The mathematical formula of the causal relationship k was used to proof the hypothesis, whether there is a cause-effect relationship between human papillomavirus and cervical carcinoma. Significance was indicated by a p-value of less than 0.05. Result: The studies analyzed (sample size N = 7657) were able to provide strict evidence that human papillomavirus is a necessary condition (a conditio sine qua non) of cervical carcinoma. Furthermore, the studies analyzed provide impressive evidence of a cause-effect relationship (k = +0.723669245, p value < 0.00001) between human papillomavirus and cervical carcinoma. Conclusion: Human papillomavirus is the cause of human cervical carcinoma.
Highlights
For the questions addressed in this paper, was searched Pubmed for case-control studies conducted in any country and published in English which investigated the relationship between human papilloma virus and cervical cancer at least by polymerase chain reaction (PCR)
The data reviewed by this article which investigated the relationship between the presence of human papillomavirus DNA and human cervical cancer are viewed by the table (Table 1)
The data as published by studies presented by the table (Table 1) do support our Null hypothesis that the sample distribution of the studies analyzed agrees with the hypothetical distribution of a necessary condition
Summary
Human papillomavirus is considered to be one of the most important risk factors in the development of cervical cancer while sexual transmission is the predominant route of HPV infection. Treatment options for patients with cervical cancer depend on several factors and include surgery or a concurrent chemo-radiotherapy regimen consisting of cisplatin-based chemotherapy with external beam radiotherapy and brachytherapy. A large and consistent body of studies (case series, case-control studies, cohort studies, and intervention studies) documented a relationship between a human papillomavirus (HPV) infection, the oncogenic subtypes such as HPV 16 and 18, and the development of human cervical cancer. In the absence human papillomavirus (HPV) viral DNA, human cervical cancer appears not to develop. Most studies conducted identified human papillomavirus as key risk factors of human cervical cancer. Even if the research in relation to the etiology of human cervical cancer has made substantial progress, a cause or the cause of human cervical cancer is still not identified
