Abstract
Female-specific cancers are the most common cancers in women worldwide. Early detection methods remain unavailable for most of these cancers, signifying that most of them are diagnosed at later stages. Furthermore, current treatment options for most female-specific cancers are surgery, radiation and chemotherapy. Although important milestones in molecularly targeted approaches have been achieved lately, current therapeutic strategies for female-specific cancers remain limited, ineffective and plagued by the emergence of chemoresistance, which aggravates prognosis. Recently, the application of nanotechnology to the medical field has allowed the development of novel nano-based approaches for the management and treatment of cancers, including female-specific cancers. These approaches promise to improve patient survival rates by reducing side effects, enabling selective delivery of drugs to tumor tissues and enhancing the uptake of therapeutic compounds, thus increasing anti-tumor activity. In this review, we focus on the application of nano-based technologies to the design of novel and innovative diagnostic and therapeutic strategies in the context of female-specific cancers, highlighting their potential uses and limitations.

Abstract
Human papillomavirus (HPV) is an essential but not a sufficient cervical cancer etiological factor. Cancer promoters, such as host genetic mutations, significantly modulate therapeutic responses and susceptibility. In cervical cancer, of interest have been viral clearing genes and HPV oncoprotein targets, for which conflicting data have been reported among different populations. This expert analysis evaluates cervical cancer genetic susceptibility biomarkers studied in African populations. Notably, the past decade has seen Africa as a hotbed of biomarker and precision medicine innovations, thus potentially informing worldwide biomarker development strategies. We conducted a critical literature search in PubMed/MEDLINE, Google Scholar, and Scopus databases for case-control studies reporting on cervical cancer genetic polymorphisms among Africans. We found that seven African countries conducted cervical cancer molecular epidemiology studies in one of Casp8, p53, CCR2, FASL, HLA, IL10, TGF-beta, and TNF-alpha genes. This analysis reveals a remarkable gap in cervical cancer molecular epidemiology among Africans, whereas cervical cancer continues to disproportionately have an impact on African populations. Genome-wide association, whole exome- and whole-genome sequencing studies confirmed the contribution of candidate genes in cervical cancer. With such advances and omics technologies, the role of genetic susceptibility biomarkers can be exploited to develop novel interventions to improve current screening, diagnostic and prognostic methods worldwide. Exploring these genetic variations is crucial because African populations are genetically diverse and some variants or their combined effects are yet to be discovered and translated into tangible clinical applications. Thus, translational medicine and flourishing system sciences in Africa warrant further emphasis in the coming decade.

Abstract
Head and neck cancer (HNC) is the leading cancer in Sri Lankan males and second most common cancer among Sri Lankan females. This is the first study, to the best of our knowledge, that has focused on investigating the association between TP53 somatic DNA variants, with p53 protein expression and risk factors in a cohort of Sri Lankan patients with HNC. A total of 44 patients with cancer and 20 healthy controls were studied. In total, 36 genomic DNA sequence variants were found, including several novel variants (two deletions in exons 4 and 6, two in the 3′ untranslated region and several intronic variants). A total of 14 tumour samples carried pathogenic TP53 mutations. A random selection of 24 samples was analysed immunohistochemically for p53 protein expression. All the samples with point missense variants were strongly immuno-positive, whereas, samples with nonsense and frameshift TP53 variants were immuno-negative for p53 immunohistochemical staining. Although, the human papilloma virus is a known risk factor for HNC, results from the present study identified an absence or lower level of infection in the Sri Lankan cohort.

Abstract
Human papilloma virus (HPV) is considered to be responsible for a large part of vaginal and vulvar carcinomas, and the p53 codon 72 polymorphism has been implicated in susceptibility to cancer induced by this virus, but with contradicting results. In this study, we have investigated the prognostic value of the codon 72 polymorphism by real-time PCR (qPCR) in two cohorts of vaginal (n = 66) and vulvar (n = 123) carcinomas. In vaginal carcinoma, arginine homozygous patients were significantly associated with a higher primary cure rate (p = 0.023) but also associated with a higher recurrence rate (p = 0.073), significant at distant locations (p = 0.009). No significant differences were found in overall survival rate (p = 0.499) or cancer-specific survival rate (p = 0.222). A higher frequency of arginine homozygosity was noted in HPV-positive tumors (p = 0.190) in comparison with HPV-negative tumors. In vulvar carcinoma, the genotype homozygous for arginine was significantly associated with a larger tumor size at diagnosis in the entire cohort (p = 0.015) and a lower cancer-specific survival rate (p = 0.024) compared with heterozygous (arginine/proline) in HPV-negative tumors. Our results indicate that the relation between HPV and the p53 codon 72 polymorphism is complex and the significance and mechanisms responsible for this relationship need to be further elucidated.

Abstract
The p53 gene is inactivated by the human papillomavirus (HPV) E6 protein in the majority of cervical cancers. Treatment of HeLa S3 cells with siRNA for HPV E6 permitted adenovirus-mediated transduction of a p53 gene linked to an upstream estrogen response element (ERE). Our previous study in non-siRNA treated HHUA cells, which are derived from an endometrial cancer and express estrogen receptor β, showed enhancing effects of an upstream ERE on adenovirus-mediated p53 gene transduction. In HeLa S3 cells treated with siRNA for HPV E6, adenovirus-mediated transduction was enhanced by an upstream ERE linked to a p53 gene carrying a proline variant at codon 72, but not for a p53 gene with arginine variant at codon 72. Expression levels of p53 mRNA and Coxsackie/adenovirus receptor (CAR) mRNA after adenovirus-mediated transfer of an ERE-linked p53 gene (proline variant at codon 72) were higher compared with those after non-ERE-linked p53 gene transfer in siRNA-treated HeLa S3 cells. Western blot analysis showed lower β-tubulin levels and comparatively higher p53/β-tubulin or CAR /β-tubulin ratios in siRNA-treated HeLa S3 cells after adenovirus-mediated ERE-linked p53 gene (proline variant at codon 72) transfer compared with those in non-siRNA-treated cells. Apoptosis, as measured by annexin V binding, was higher after adenovirus-mediated ERE-linked p53 gene (proline variant at codon 72) transfer compared with that after non-ERE-linked p53 gene transfer in siRNA-treated cells.

Abstract
This study was designed to obtain a conclusive result about the relevance of p53 codon 72 polymorphism to the risk of cutaneous squamous cell carcinoma (SCC). We performed an updated meta-analysis of 3,792 subjects (1,349 cancer cases and 2,443 controls) to summarize the data available for p53 codon 72 polymorphism and SCC risk. The association was estimated by odds ratios (ORs) with 95% confidence intervals (CIs). The meta-analysis showed no statistical significance for SCC risk associated with any of the genetic models of p53 codon 72 polymorphism. The analyses by ethnic subgroup also failed to produce significant associations. This study suggests that p53 codon 72 polymorphism does not appear to represent a significant susceptibility factor for SCC in Caucasians.

Abstract
Human papillomavirus (HPV) infection including sub-strain identification was studied in patients with squamous cell cervical cancer (SCCA) in Northeastern Thailand. Subjects were 90 cases of SCCA and 100 healthy controls. Prevalence of high-risk group of HPV infection in the controls and the SCCA patients were 13.0% and 86.7%, respectively. The HPV infection significantly increased the risk for cervical cancer 43.5-fold (95% confidential interval: 17.5-110.6; P <0.00001). Among HPV carrier patients with SCCA (n = 78), HPV-16 was also prominent (70.5%) followed by HPV-18 (23.1%). There was no statistical difference in the subtype distribution between the SCCA and the control groups. There was no significant association between genotype distribution of the p53 codon 72 polymorphism and HPV infection. HPV infection was confirmed as a critical risk factor for cervical cancer development in Northeast Thailand. Since polymorphism of the p53 itself as well as in combination with HPV infection may not be a genetic risk for cervical cancer, much attention should be paid to other risk factors such as sexual behavior and smoking.

Abstract
Cervical cancer is the second most common cancer in women worldwide. This is caused by oncogenic types of human papillomavirus (HPV) infection. Although large numbers of young sexually active women get HPV-infected, only a small fraction develop cervical cancer. This points to different co-factors for regression of HPV infection or progression to cervical cancer. Host genetic factors play an important role in the outcome of such complex or multifactor diseases such as cervical cancer and are also known to regulate the rate of disease progression. The aim of this review is to compile the advances in the field of host genetics of cervical cancer. MEDLINE database was searched using the terms, ‘HPV’, ‘cervical’, ‘CIN’, ‘polymorphism(s)’, ‘cervical’+ *the name of the gene* and ‘HPV’+ *the name of the gene*. This review focuses on the major host genes reported to affect the progression to cervical cancer in HPV infected individuals.

Abstract
The objective of this study was to identify whether polymorphic variants of p53 at codon 72 and p21 at codon 31 were associated with increased risk for cervical cancer, either independently or jointly, among Chinese women from southern Han. We genotyped p53 codon 72 and p21 codon 31 polymorphisms of peripheral blood DNA from 104 cervical cancer patients and 160 controls. Genotyping was confirmed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct DNA sequencing. We observed an increased risk of cervical cancer associated with the p53 Arg/Arg (OR, 2.25; 95% CI, 1.11-4.54) or p21 Ser/Ser (OR, 2.09; 95% CI, 1.04-4.19) genotype, compared with the p53 Pro/Pro or p21 Arg/Arg genotype, respectively. In additional, interaction between these p53 and p21 polymorphisms increased the risk of cervical cancer in a multiplicative manner, with the OR being 3.96 (95% CI, 1.51-10.41) for subjects carrying both p53 Arg/Arg and p21 Ser/Ser genotypes. These findings suggest that there is a significant association between the genetic polymorphism of p53, p21, and the risk of cervical cancer among Chinese southern women, and there is a possible gene-gene interaction in the incidence of cervical cancer.

Abstract
The purpose of this study was to determine the prevalence of TP53 polymorphism at codon 72 and its association with environmental risk factors in a sample of women in Rio de Janeiro, Brazil. A cross-sectional study was conducted with 304 women with histological diagnoses of negative, precancerous, and cancerous lesions between October 2004 and May 2006. Antecedents of exposure to environmental risk factors were ascertained through an interview-administered questionnaire, and whenever indicated, colposcopy tests and lesion excisions were performed. Genomic DNA was extracted from leukocytes of peripheral blood subjects, and genotyping of TP53 polymorphism was conducted using polymerase chain reaction and restriction fragment-length polymorphism methods. Crude and adjusted odds ratios (OR) and their 95% confidence intervals (CI) were ascertained for selected risk factors and allelic groups among control, low-grade squamous intraepithelial lesion (LSIL), and high-grade squamous intraepithelial lesion (HSIL)/cancer strata, using logistic regression analysis. The TP53 polymorphism distribution in this population was 64 (21.1%) Arg/Arg, 55 (18.1%) Pro/Pro, and 185 (60.9%) Arg/Pro. Women who were heterozygous (Arg/Pro) showed an independent risk for cervical HSIL/cancer (adjusted OR: 1.92, 95%CI: 1.03-1.59, controlled for age, ethnicity, and age at menarche) compared to Pro/Pro genotypic women. Age at sexual onset up to 16 yr old (adjusted OR: 1.97, 95%CI: 1.18-3.3), lifelong 3-4 sexual partners (adjusted OR: 2.38, 95%CI: 1.32-4.28), current smoking (adjusted OR: 2.32, 95%CI: 1.31-4.13), and smoking more than 10 yr (adjusted OR: 2.52, 95%CI: 1.042-6.09) were found to be independent risk factors for cervical HSIL/cancer. Women possessing the Arg/Pro genotype presented a higher risk for HSIL/cancer development compared to Pro/Pro genotypic women in the sample studied after control for selected confounders. Early sexual onset, multiple sexual partners, and current and past tobacco smoking were independent risk factors for HSIL/cancer development.

Abstract
The p53 gene has been referred to as 'the guardian of the genome' because it controls apoptosis and cell cycle arrest. The purpose of this study was to evaluate the association of p53 codon 72 genetic polymorphism and the p53 immunohistochemistry with Helicobacter pylori-associated gastroduodenal diseases, including gastric cancer. This study included 1,852 subjects: controls and patients with gastric cancer, dysplasia, benign gastric ulcers, and duodenal ulcers (DU). Biallelic polymorphism was genotyped by restriction fragment length polymorphism. Immunohistochemical analysis for the detection of mutant type p53 expression was performed. The frequency of the Pro/Pro allele of the p53 codon 72 was higher in the patients with H. pylori-positive dysplasia than in controls (OR: 2.3, 95% CI: 1.3-4.3), but it was less frequent among patients with a H. pylori-positive DU (OR: 0.5, 95% CI: 0.3-0.8). However, there was no significant association with gastric cancer, including the location, stage, or histological type of gastric cancer. Expression of a mutant type of p53 protein was detected in 6.3% of dysplastic tissues and 26.5% of cancerous tissues compared 0% in the controls. Positive expression was higher in the intestinal type of cancer (34.9%) than in the diffuse type (15.0%; P = 0.001). These results suggest that genetic polymorphism of p53 codon 72 played a role in the determination of H. pylori-associated gastroduodenal diseases, but p53 immunostaining did not correlate with those of the p53 genetic polymorphism analysis.

Abstract
We hypothesized that the polymorphisms in the two p53 family genes (p53 Arg72Pro and p73 G4C14-to-A4T14 at exon 2 (G4A)) and p21 Ser31Arg polymorphism might modulate the risk of non-Hodgkin's lymphoma, and conducted a hospital-based prevalent case control study at Aichi Cancer Center Hospital to clarify the association. Risk estimation for each genotype by the unconditional logistic model demonstrated the possible association between the p53 Pro72 allele and the risk of non-Hodgkin's lymphoma in Japanese population (OR = 1.59; 95% CI, 0.99-2.57, P = 0.057), although no other significant association was observed. The analyses of statistical interactions between these three polymorphisms (p73 G4A, p53 Arg72Pro and p21 Ser31Arg polymorphisms) revealed the marginally significant OR for interaction between p53 Arg72Pro and p73 G4A polymorphisms (OR = 2.54; 95% CI, 0.97 6.62, P = 0.057). When those without p53 Pro72 and p73 A4T14 alleles were defined as a reference, those with p53 Pro72 and p73 A4T14 alleles demonstrated a significantly higher OR (2.08; 95% CI, 1.11-3.90, P = 0.023). Further examination with a sufficiently larger population and other ethnicities are required to confirm our findings.

Abstract
The polymorphisms of the tumor suppressor gene p53 have been extensively investigated in numerous malignant tumors, particularly carcinomas associated with human papillomavirus (HPV) infection. However, the results remain controversial. To address a potential correlation between the p53 genotypes and the risk of esophageal squamous cell carcinoma (ESCC), we investigated the p53 codon 72 polymorphism in 435 patients with ESCC and 550 cancer-free subjects from the same geographical region. p53 Arg/Arg genotype was significantly increased in ESCC cases compared with control subjects (85.7 vs. 49.6%, P < 0.001), resulting in an elevated ESCC risk (OR = 6.48, 95% CI = 4.65-9.03). In addition, among p53 Arg/Arg carriers, HPV infection, smoking, and drinking might further increase the risk of ESCC development.

Abstract
Human papillomaviruses (HPVs), with over 100 genotypes, are a very complex group of human pathogenic viruses. In most cases, HPV infection results in benign epithelial proliferations (verrucae). However, oncogenic types of HPV may induce malignant transformation in the presence of cofactors. For example, over 99% of all cervical cancers and a majority of vulval, vaginal, anal and penile cancers are the result of oncogenic HPV types. Such HPV types have been increasingly linked to other epithelial cancers involving the skin, larynx and oesophagus. Although viral infection is necessary for neoplastic transformation, evidence suggests that host and environmental cofactors are also required. Research investigating HPV oncogenesis is complex and quite extensive. The inability to produce mature HPV virions in animal models has been a major limitation in fully elucidating the oncogenic potential and role of associated cofactors in promoting malignant transformation in HPV-infected cells. We have reviewed the literature and provide a brief account of the current understanding of HPV oncogenesis, emphasizing the role of genetic susceptibility, immune response, and environmental and infectious cofactors.

Abstract
Cervical cancer is one of the most common tumor affecting women worldwide. Human papillomavirus (HPV) was found to have a causal relationship with cervical cancer and its precursors. The interaction between HPV E6 protein and p53 was identified in in vitro studies. The aim of the study was to evaluate the prevalence of p53 alterations related to HPV infection and the prognostic significance of p53 alterations in cervical cancer. Studies were identified by a MEDLINE search, and all relevant articles were retrieved from 1991 to March 2004. The prevalence of p53 mutations is a rare event in cervical cancer. The correlation between p53 mutations and HPV or prognosis is controversial. Loss of heterozygosity (LOH) of p53 is more commonly found in cervical cancer and is related with the prognosis of this disease. There is no significant correlation between p53 polymorphism and development of cervical cancer. The p53 mutations were not commonly found in cervical cancer. LOH of p53 may contribute to the progression of this malignancy. p53 polymorphism failed to be an independent prognostic factor in predicting the outcome of patients with cervical cancer. Further, epidemiologic surveys should be undertaken in larger populations and in different geographical regions.

Abstract
BACKGROUND p53 polymorphism at codon 72 is a known risk marker for various malignancies, but it has not been studied in hypopharyngeal cancer. This study investigated the genotype distribution of p53 codon 72 polymorphism in hypopharyngeal cancer patients and non-cancer controls matched for age, gender, alcohol consumption and smoking habit. METHODS Genomic DNA was extracted from peripheral blood cells of 53 patients with hypopharyngeal cancer and 53 non-cancer controls. Codon 72 polymorphism of p53 was identified by polymerase chain reaction-restriction fragment length polymorphism. RESULTS Patients with hypopharyngeal cancer had higher frequencies of Pro/Pro (26.4% vs. 13.2%) and Pro/Arg (51.0% vs. 45.3%) but lower frequencies of Arg/Arg (22.6% vs. 45.1%) compared to controls. Compared to Arg/Arg genotypes, Pro/Pro genotypes had a relative risk of hypopharyngeal cancer of 3.667 (95% confidence interval, 1.16-11.56; p = 0.03). As a group, patients with Pro/Pro or Arg/Pro who were carriers of the Pro allele had a higher relative risk of hypopharyngeal cancer compared to Arg homozygous carriers (odds ratio, 2.415; 95% confidence interval, 1.04-5.64; p = 0.04). CONCLUSION This study demonstrated that p53 codon 72 Pro homozygosity is associated with a higher risk of developing hypopharyngeal cancer.

Abstract
High-risk human papillomavirus are essential for the development of cervical cancer; however, TP53 is the most frequently altered tumor suppressor gene among tumors and is described as a cofactor for cervical carcinogenesis. TP53 has two common polymorphic forms encoding either proline or arginine, at position 72, and the presence of homozygous arginine has been reported as a risk factor for cervical cancer in many populations. We evaluated the effect of this TP53 polymorphism in a northern Portuguese population. We analyzed blood samples of 385 women; 20 with low-grade squamous intraepithelial lesion (SIL), 56 with high-grade SIL, 164 with invasive cervical cancer, and 145 healthy controls, using allele specific-polymerase chain reaction methodology. We observed an increased frequency of the Arg/Arg genotype in the cancer group, but no statistical significance was found between cases and controls (P>0.05). Our results indicate that there is no association between the presence of the Arg allele in codon 72 of TP53 polymorphism and risk of cervical cancer in our population.

Abstract
BACKGROUND The p53 protein is expressed in pterygial epithelium, but the reported prevalence of its expression varies widely. Although the cause of this variation is unknown, several factors that may play a role have been investigated, but without conclusive findings. In the present study, the role of p53 codon 72 polymorphism, and that of both age and gender, on p53 expression in pterygium was investigated. METHODS Pterygium and blood samples were harvested from 55 patients undergoing pterygium surgery. The pterygial specimens were studied immunohistochemically using antibodies against p53 protein. Polymerase chain reaction based analysis was used to resolve the p53 codon 72 polymorphism. RESULTS Thirty-one (56.4%) of the 55 pterygial specimens were positive for p53 staining. The distributions of the three genotypes of the p53 codon 72 polymorphism in the p53-positive and -negative staining groups were not statistically different. The allelic frequency in the two groups was also not statistically different, nor was there any significant difference between both groups with respect to age or gender. CONCLUSIONS A correlation between p53 codon 72 polymorphism, sex and gender and p53 protein expression was not found.

Abstract
Cervical cancer mortality is high in Texas, especially among Hispanic women living in south Texas and adjacent Mexico. Though human papillomavirus (HPV) infection has a causal role in the development of cervical cancer, there are no published data on the prevalence of HPV genotypes in this underscreened region. We studied 398 Hispanic women on both sides of the border along the lower Rio Grande River to determine the prevalence of HPV genotypes and risk factors for cervical cancer. Using a nested PCR system HPV was detected in 62% of cervical specimens, including all the known high-risk HPV genotypes, with HPV16 and HPV18 the most frequent (30.6% and 23.0%, respectively). Multiple infections were common (29.4% of the infected specimens), and where this occurred we were more likely to find high-risk HPV genotypes. We examined host p53 codon 72 genotype frequencies and found that patients with cervical abnormalities and women with HPV16 and HPV18 infections had a lower genotype frequency of the homozygous (AA) previously reported to be associated with cervical cancer, than uninfected women with no abnormalities. In this US/Mexico border population high rates of potentially oncogenic HPV viruses and multiple infections are consistent with observed elevated cervical cancer rates. These data are further evidence that in this underserved population HPV infections are associated with high rates of malignancy, but that host p53 genotypic variations are unlikely to be primary factors in oncogenesis.

Abstract
Relationships between cervical cancer and risk factors were investigated in Northeastern Thailand. Cases (n = 90) with squamous cell cervical cancer (SCCA) and age matched healthy controls (n = 100) were recruited. The p53 codon 72 polymorphism, proline and arginine allele, was studied by the polymerase chain reaction-restriction fragment length polymorphism. There was no significant difference in the allele and the genotype distribution between the SCCA and the control groups (P > 0.05). Significant difference was observed in the number of sexual partners (P < 0.003) age at the first sexual intercourse (P < 0.03) and number of parities ( P< 0.006). After adjusted by age and p53 genotype, significant difference was still observed in the number of sexual partners (P = 0.017) The partners' smoking increased the risk to develop SCCA. Increased odds ratios were observed when the partner had smoking history both at present (3.31; P < 0.003) and in the past (3.36; P < 0.003). The p53 polymorphism itself may not be a risk factor for cervical cancer in Northeastern Thailand. Much attention should be paid to the presence of other risk factors such as sexual behaviors and smoking habits in the prevention of cervical cancer in this region.

Abstract
BACKGROUND The aim of this study was to identify gene-gene and gene-environmental factors affecting cervix carcinogenesis in Korean women. METHODS We evaluated 530 subjects composed of 185 female cervix cancer patients and 345 normal healthy women. The single nucleotide polymorphisms (SNPs) of p53 codon 72, p21 codon 31, and interferon regulatory factor-1 (IRF-1) intron 6 were evaluated from extracted DNA of peripheral blood with an automatic DNA sequencer. The differences of each SNP, gene-gene and gene-environmental interactions between normal controls and patients were evaluated in the adjusted environmental background. RESULTS In the environmental aspect, the rate of cervix cancer increased in the women with a lower level of education, a younger age at first sexual intercourse and more childbearing. The women who had p53 (Arg/Arg), IRF-1 (T/T), and <6 years of education showed a 14.7-fold increased risk of cervix cancer compared to the women who had p53 ( approximately Pro), IRF-1 ( approximately C), and >15 years of education. The women who had p53 (Arg/Arg), p21 (Ser/Ser), and >3 children showed a 6.4-fold increased risk of cervix cancer compared to the women who had p53 ( approximately Pro), p21 ( approximately Arg), and no children. The women who had p53 (Arg/Arg), IRF-1 (T/T), and first sexual intercourse before 22 years old showed a 5.5-fold increased risk of cervix cancer compared to the women who had p53 ( approximately Pro), IRF-1 ( approximately C), and first sexual intercourse after 26 years old. CONCLUSIONS We found that the level of education, the age at first intercourse, and the number of children were independent risk factors in cervix carcinogenesis. The specific combinations of p53, p21, and IRF-1 gene-gene and gene-environmental interactions were significantly noted in the cervix carcinogenesis of Korean women.

Abstract
Head and neck squamous cell carcinoma is a disease associated with tobacco and alcohol abuse. There is evidence that the oncogenic human papillomavirus (HPV) may also be a risk for upper aerodigestive tract cancers. High-risk HPVs encode two early proteins, E6 and E7, that can bind to p53 and pRb, respectively, and induce its degradation or inactivation. The TP53 gene has a single polymorphism at codon 72 of exon 4 that encodes either arginine (Arg) or proline (Pro). The purpose of this study was to evaluate the role of HPV infection and TP53 polymorphism in head and neck cancer. We analyzed 50 tumors, as well swabs of oral mucosa from 142 control individuals, with a polymerase chain reaction technique. The prevalence of HPV in controls was 10.6% and in cancer specimens 16%. The frequency distribution of genotypes in controls was 50% Arg/Arg, 43% Arg/Pro and 7% Pro/Pro; in tumors, it was 52% Arg/Arg, 32% Arg/Pro, and 16% Pro/Pro. Contrary to the results of some studies on cervical cancer, no association between any TP53 genotype or allele and the development of head and neck cancer was observed, regardless of HPV status, except for the Pro/Pro genotype, which is associated with the absence of HPV. The arginine allele appears to protect against head and neck cancers. Also, the data showed that HPV infection results in no increased risk of developing head and neck tumors.

To examine the possible association between cervical cancer and p73 G4C14-to-A4T14 in exon 2 and p53 Arg72Pro polymorphisms, an incident case-control study was conducted in Japanese. The cases were 112 cervical cancer patients. Controls were 320 healthy women and 122 non-cancer female outpatients. Risk estimation for each genotype by an unconditional logistic model demonstrated a possible association between the p73 A4T14 variant and the risk of cervical cancer in our Japanese population (OR = 1.57; 95%CI, 0.99-2.48, P = 0.053). There was no significant difference in the p53 Arg72Pro genotype frequency between the controls and cases.

Abstract
The Arg/Arg genotype versus Arg/Pro or Pro/Pro at codon 72 of the p53 gene has been implicated as a risk marker in cervical neoplasia. However, research on this topic has produced controversial results. We reviewed the published literature to summarize the association and to identify methodological features that may have contributed to the heterogeneity. Information on specific methodological features of studies addressing this topic published between 1998 and 2002 were obtained. Study-specific odds ratios (ORs) were combined in a meta-analysis, assuming random effects. To identify characteristics that significantly contributed to heterogeneity, we used meta-regression analysis. We identified 50 articles, of which 45 were included in the meta-analyses and regressions. No evidence of association or heterogeneity was detected for preinvasive lesions. For invasive cervical cancer with undefined histology, the Arg/Arg genotype was not found to affect risk (OR, 1.1; 95% confidence interval (CI), 0.9-1.3). However, a slightly increased risk was observed for squamous cell carcinoma (OR, 1.5; 95% CI, 1.2-1.9) and adenocarcinoma (OR, 1.7; 95% CI, 1.0-2.7). Meta-regression analysis identified that the most important factor contributing to heterogeneity among results for invasive lesions was departures from Hardy-Weinberg equilibrium in the control group. Summary ORs for studies in equilibrium were essentially null. A possible susceptibility role by the p53 codon 72 polymorphism at a late carcinogenetic stage in cervical cancer cannot be ruled out. However, various methodological features can contribute to departures from Hardy-Weinberg equilibrium and consequently to less than ideal circumstances for the examination of this polymorphism. Future investigations require appropriate attention to design and methodological issues.

Abstract
The p53 gene plays an important role in cell cycle control, facilitating DNA repair activities in response to DNA damage. Aberrant cell cycle control impairs DNA repair and increases the probability of mutations that can lead to carcinogenesis. The p53 gene is polymorphic at codon 72 (Arg/Pro) of its protein, which is functionally distinct, leading to inquiry into its role in carcinogenesis. In this hospital-based case-control study of 289 newly diagnosed patients with melanoma and 308 cancer-free control subjects, we evaluated whether the p53 codon 72 variant is associated with risk of cutaneous melanoma (CM). The controls were frequency-matched to the cases by age, sex, and ethnicity. The frequency of the p53 Arg allele was 78.2% in cases and 73.2% in controls (p=0.045), and the genotype frequencies of p53 Arg/Arg, Arg/Pro, and Pro/Pro were 62.6%, 31.1%, and 6.3%, respectively, in the cases, and 53.9%, 38.6%, and 7.5%, respectively, in the controls (p=0.096). Logistic regression analysis revealed that the p53 Arg/Arg genotype was associated with a significantly increased risk of melanoma (adjusted odds ratio (OR)=1.43; 95% confidence interval (CI)=1.02-2.02) compared with other genotypes, and this association was more evident in subgroups of older subjects (OR=2.32; 95% CI=1.39-388), and subjects with Fitzpatrick's skin type III or IV (OR=1.69; 95% CI=1.11-2.59). In conclusion, this study found some evidence that in subjects over 50, p53 Arg/Arg genotype is associated with increased risk of CM as compared to genotypes Arg/Pro or Pro/Pro. Further larger studies are needed to substantiate our findings.

Abstract
OBJECTIVES Although some studies have reported that the arginine isoform on codon 72 of p53 increases the susceptibility to invasive cervical cancer, such data remain controversial. The objective of this study was to quantitatively summarize the evidence for such a relationship. METHODS Our data sources consisted of a MEDLINE search of the literature published before December 2002, bibliography review, and expert consultation. Thirty-seven studies met the inclusion criteria. Information on sample size, study design, Hardy-Weinberg equilibrium, and method of genotype determination was abstracted by two reviewers using a standardized protocol. The overall odds ratio (OR) of the p53 gene on invasive cervical cancer was estimated using the Mantel-Haenzel method. RESULTS The overall OR (95% confidence interval) for cervical cancer among those with the homozygous mutant (Arg/Arg) was 1.2 (1.1-1.3, P=0.001) compared with those with the heterozygous mutant (Arg/Pro). By a cellular type of cervical cancer, the overall OR among those with Arg/Arg was statistically significant in adenocarcinomas (1.7, 1.1-2.6, P=0.024), but not in squamous cell carcinomas (1.1, 0.9-1.2, P=0.960), compared with Pro/Pro. Compared with Arg/Pro, the OR among those with Arg/Arg was statistically significant in HPV types 16 (1,5, 1.2-2.0, P=0.002). CONCLUSIONS Overall, the p53 gene was associated with increased risk for invasive cervical cancer. However, the risk varied by country, cellular, and HPV type.

Abstract
The p53 tumor suppressor gene is often mutated in various human cancers. Recently, the p53 codon 72 polymorphism has been extensively studied to determine the risk factors responsible for cancer formation. We investigated the genotype distribution of the p53 codon 72 polymorphism in 112 male urothelial cancer cases and 175 male unrelated non-cancer controls. The allelic frequencies in Japanese non-cancer controls were 0.58 (Arg) and 0.42 (Pro). There was no significant difference in the three genotype frequencies (Arg/Arg, Arg/Pro, Pro/Pro) of the p53 codon 72 between the urothelial cancer cases and the controls. However, stratifying by smoking status, we found that the frequency of the Pro/Pro genotype for smokers was significantly more than that for never-smokers (odds ratio (OR)=2.28, 95% confidence interval (95%CI)=1.12-4.66). Furthermore, we divided smoking status (pack-years) into quartiles (<20, 20-40, 40-60, >60). OR (Pro/Pro vs. Arg/Arg) for the lighter smokers (<20 pack-years) was higher than in other groups (OR=6.83). Our results suggest that the Pro/Pro genotype of the p53 codon 72 polymorphism increases the risk of urothelial cancer in smokers.

Abstract
The association of p53 codon 72 polymorphism with cancer has been investigated by several scientific groups with controversial results. In the present study, we examined the genotypic frequency of this polymorphism in 54 patients with advanced lung cancer and 99 normal controls from the geographical region of Greece. Sputum and bronchial washing samples from each patient were assayed for the presence of human papillomavirus. Codon 72 heterozygous (Arg/Pro) patients were also analysed for loss of heterozygosity at the TP53 locus, in order to determine the lost p53 allele (Arg or Pro). p53 Arg/Arg genotype was significantly increased in lung cancer patients compared to normal controls (50% vs 24.2%, P<0.002). Human papillomavirus was detected only in two patients (3.7%). Loss of heterozygosity at the TP53 locus was found in 14 out of 27 Arg/Pro patients (51.85%). The Pro allele was lost in 11 cases (78.6%), while the Arg allele was lost in three (21.4%). Our results suggest that p53 codon 72 Arg homozygosity is associated with advanced lung cancer, and that the Arg allele is preferentially retained in patients heterozygous for this polymorphism. On the other hand, human papillomavirus infection does not seem to play an important role in lung carcinogenesis.

Abstract
p53 plays an important role in cell-cycle control, as it facilitates DNA repair activities in response to DNA damage. An aberrant cell cycle impairs DNA repair and increases the probability of mutations that lead to carcinogenesis. The p53 codon 72 Arg/Pro polymorphism has been suggested to be associated with susceptibility to tobacco-related cancers, but this association remains controversial. In this hospital-based case-control study of 304 patients newly diagnosed with squamous cell carcinoma of the head and neck (SCCHN) and 333 cancer-free controls, we evaluated the association between this p53 polymorphism and the risk of SCCHN. All subjects were non-Hispanic whites, and the controls were frequency-matched to the cases by age (+/-5 years), sex and smoking status. Our results suggested that there was no difference in the distributions of p53 codon 72 genotypes between cases and controls (odds ratio (OR)=1.04, 95% confidence interval (CI) 0.75-1.44 for Pro/Pro vs. Arg/Arg and OR=1.01, 95% CI 0.54-1.91 for Arg/Pro vs. Arg/Arg). However, there was evidence that the Pro allele was associated with an early age of onset of SCCHN. The median ages of onset of SCCHN were 59, 56 and 53 years for Arg/Arg, Arg/Pro and Pro/Pro cases, respectively (P=0.151 among three genotypes; P=0.057 for Pro/Pro and Arg/Pro combined vs. Arg/Arg). The median ages at onset of oral cancers were 62, 57 and 51 years for Arg/Arg, Arg/Pro and Pro/Pro, respectively (P=0.091 among three genotypes; P=0.046 for Pro/Pro vs. Arg/Arg; P=0.066 for Pro/Pro and Arg/Pro combined vs. Arg/Arg). While the results suggest that the P53 codon 72 polymorphism may contribute to oral cancer susceptibility, larger studies are needed to confirm these findings.
