The general objective of this article is to review the current literature regarding the epidemiology, biological behavior and risk factors for penile cancer development, such as HPV infection. Phimosis and chronic irritation related to poor hygiene are commonly associated with penile cancer, whereas neonatal circumcision reduces the relative risk for the(More)
Soft tissue sarcomas (STS) are tumors of mesodermal origin, comprising about 1% of all adult neoplasms. Management of such tumors is an important medical challenge. TP53 codon 72 polymorphism results in either the arginine or proline form of the p53 protein; several studies have investigated whether codon 72 polymorphisms are risk and prognostic factors for(More)
Human papillomavirus (HPV) has been cited as a possible initiating agent in the pathogenesis of oral cancer. However, the literature tends to be both controversial and inconclusive about the prevalence of HPV and its potential for proliferation in oral squamous cell carcinoma (SCC). The aim of this study was to investigate the cellular proliferation and the(More)
The human leukocyte antigen G (HLA-G) is a non-classical HLA class I molecule predominantly expressed in trophoblastic placental cells to protect the fetus during pregnancy. However, evidence has shown that this molecule may be implicated in the immune escape mechanism of tumor cells. Thus, the aim of this study was to evaluate the frequency of 14-bp(More)
The present study aimed to evaluate the applicability of an educational booklet that contained information for the general population about promotion and prevention of infections and neoplasic process caused by the human papillomavirus (HPV). The study was arranged in two phases. First, the booklet was given to 200 volunteers in the city of Goiânia, Goiás(More)
The value of repeat cytology in the detection of high-grade preinvasive or invasive disease was analyzed at the time of colposcopy in cases of patients with abnormal referral cytology. A series of 136 patients with squamous abnormalities in their referral cytology, who had undergone repeat cytology and for whom outcome had been established, were included in(More)
Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer and can present as lymph node metastasis in 30 to 65% of cases when initially diagnosed. High frequency recurrence, distant metastasis and treatment resistance can be found in cases of PTC so early diagnosis and treatment are critical for improved prognosis and better survival(More)
Behavioral risks such as age at first sexual intercourse, number of sexual partners and partner’s sexual behavior are associated with an increased risk of HPV infection, persistence of the infection and the development of neoplastic precursor lesions. The objective of this study was to evaluate the risk factors associated with HPV positivity and with a(More)
This study was conducted in order to investigate the implications of the R72P polymorphism in the TP53 gene in breast cancer risk. The enlightenment of this matter might provide a piece of information about the potential implications of this polymorphism in patient risk. A meta-analysis was conducted considering a large sample size from studies with(More)
BACKGROUND Human papillomavirus and Chlamydia trachomatis share the same route of sexual transmission and possess similar risk factors, indicating that coinfection may act synergistically in the induction of epithelial cell abnormalities. OBJECTIVE This study aimed to determine the prevalence of human papillomavirus and Chlamydia trachomatis in(More)
