Academia Mexicana de Cirugía A. A review of the clinical performance of the Aptima HPV assay. Typing was subsequently performed in HPV positive samples in order to detect types 18, 16, 11 and 6, using custom primers. Despite the increase in the risk of squamous cell carcinoma of the head and neck, better prognosis exists for patients in whom the viral DNA is detected, and who therefore cauxe greater control and a better uterjne of survival.

Human papillomavirus HPV has been the leading cause of cervical cancer for over 25 years. Approximately 5. The truly HPV-negative cervical cancers are almost all cervical adenocarcinomas with unclear etiology. HPV-negative cervical cancers are often diagnosed at an advanced FIGO stage and have a poor prognosis; thus, the management of these cases requires greater attention. Persistent infection with human papillomavirus HPVparticularly high-risk genotypes of HPV, is considered does hpv cause uterine cancer major cause of cervical cancer.

HPV DNA replicates from free DNA in the basal cells of the cervix during the initial period of HPV infection, and then integrates into the host genome as the infection progresses, with subsequent upregulation of E6 and E7 oncogene expression 3. HPV can be ph of strong acid and strong base formula in almost all cervical squamous cell carcinomas and precancerous lesions, including high grade squamous intraepithelial lesions HSILs or grade 2—3 cervical intraepithelial neoplasia CIN.

Although the sensitivity of HPV testing has improved significantly in recent years, a small fraction of cervical cancers are continued to be reported as HPV-negative. Insights into the etiology, therapy, and prognosis of HPV-negative cervical cancer may help develop appropriate strategies for its management in patients. Currently, there is no clear definition of HPV-negative cervical cancer to describe cases diagnosed by pathological features in the absence of HPV-infection via HPV testing.

The existence of cervical adenocarcinoma independent of HPV infection has been recognized by the majority of researchers 4 — 6. It is estimated that approximately 5. A review of studies and 30, women with invasive cervical cancer that were reported between and revealed a gradual decrease in the number of HPV-negative cases In this meta-analysis, the incidence of HPV-positivity in —, —, and — was The downward trend in HPV-negativity could be related to improvements in HPV testing and non-cervical cancer classification.

However, only a few rare pathological types of cervical cancer are truly HPV-negative 13 — In studies involving HPV testing, the true incidence of HPV-negative invasive cervical cancer might be overestimated This review provides a comprehensive overview of the attributable reasons, clinical characteristics, treatment, and does hpv cause uterine cancer measures for HPV-negative cervical cancer, with the aim to assist in the development of effective therapeutic strategies to improve clinical outcomes.

For HPV-negative cervical cancers, clinicians should consider whether the cervical cancer is HPV-independent, a misclassification of non-cervical cancer, or an HPV false-negative case. Cervical squamous cell carcinoma is rarely HPV-negative 17and a confirmed HPV-independent cervical squamous cell carcinoma has not does hpv cause uterine cancer been reported.

The HPV positivity rate in carcinoma in situ varies according to different histological features Cervical cancers include the direct extension of endometrial carcinoma or those arising from distant metastasis of other primary HPV-negative tumors. Therefore, it is necessary to perform immunostaining of the tumor and stroma in cases of HPV-negative results 17 to identify the primary tumor site and reduce the rate of false negativity.

Age is also a characteristic worth considering in the classification of non-cervical cancers. The classic triad, including advanced age, HPV negativity, and non-squamous carcinoma, is characteristic of uterine carcinoma instead of cervical cancer. Compared with other sites, such as the gynecologic tract, it is rare for the uterine cervix to be a metastatic site considering does hpv cause uterine cancer anatomy 23 ; however, 3.

Natural infection of HPV has a latency period, in which viral replication is restricted by the immune system and HPV gene expression is in a silent state. However, the natural history of HPV from infection to cervical cancer remains unclear A 5-year follow-up study involving sensitive HPV DNA testing revealed that most Does hpv cause uterine cancer infections disappeared within two years, except those with precancerous lesions or worse Latent infections often have a low incidence of tumorigenesis and a higher chance of false-negativity as the viral load is too low to be detected using HPV testing.

However, nearly 0. A study by Banister et al. This provides more options for targeted therapy and warrants further exploration. Several studies have reported the association between cervical cancer and infection with low-risk HPV types 6, 11, 42, 44, and 70 31 — Whether low-risk HPV causes cervical cancer or acquired by accident is does hpv cause uterine cancer. Petry et al. HPV testing can be divided into two categories, namely, nucleic and non-nucleic acid signal amplification Figure 1.

Nucleic acid signal amplification includes transcription-mediated amplification TMA and polymerase chain reaction PCR ; non-nucleic acid signal amplification includes hybridization capture and invader chemistry. Figure 1 Classification of human papillomavirus HPV testing. However, the other three methods targeting L1 alone are prone to false-negative results because of the disruption of L1 fragment during HPV genome integration.

This window phase may increase the rate of HPV false-negative outcomes. For all the HPV tests mentioned, amplification of hr-HPV targeting fragments may be affected by primer competition among different subtypes and amplification of untargeted genotypes, leading to false-negative HPV testing. In addition to the method used, HPV false-negative results are also related to sampling errors. Faulty sample collection methods, including samples mixed with blood or lubricant, as well as fixation procedure can result in false negativity.

Therefore, the accuracy of HPV testing in published studies should be questioned discreetly. Some studies employed HPV testing to investigate previously stored cervical cancer specimens, but it does hpv cause uterine cancer unknown whether such specimens precisely reflect HPV infection in the patients. A retrospective study demonstrated that samples from elderly patients or those stored for a longer duration had lower HPV-positivity rates The effect of storage time on HPV positivity was more distinct in adenocarcinoma than in squamous cell carcinoma Other factors that affect HPV positivity include the time between excision to fixation and fixator type In a retrospective study, the use of unbuffered formalin fixation was an important factor influencing HPV-negative results In summary, the most important reason for false-negative HPV testing results is the significant difference among HPV detection methods, which is not realized by all clinicians A global study involving cases of cervical adenocarcinoma revealed that older patient age at initial diagnosis was does hpv cause uterine cancer with a lower positivity rate of HPV DNA testing A similar trend was identified in squamous cell carcinoma without any clear reason.

One possible explanation is that viral vitality is gradually lost during tumor progression, especially in older patients does hpv cause uterine cancer more time to develop cancer. Another explanation is that elderly patients develop cancer via an HPV-independent mechanism 20as seen in vulvar carcinoma. Pathological type influences the results of HPV detection, as demonstrated by differences in HPV infection rates between cervical squamous cell carcinoma and adenocarcinoma.

Globally, The parakeratosis or hyperkeratosis status of squamous cell carcinoma can lead to false-negative HPV does hpv cause uterine cancer results Additionally, HPV-negative cervical cancer whose histopathology is almost all adenocarcinoma is possibly missed by HPV testing 818 The positivity rate of some HPV genotypes in cervical adenocarcinoma was reportedly low The pathological types of HPV-negative adenocarcinoma are gastric, clear cell, serous, and mesonephric adenocarcinomas Table 2.

These types are quite rare and their occurrence might not be HPV-related Table 2 Pathological types of cervical adenocarcinoma and its human papillomavirus HPV -positive rate. The pathogenesis of these HPV-independent pathological types is common risk factors for tbi include with specific mutations of the genome. HPV-negative patients are prone to develop advanced FIGO stage and lymphatic space invasion prior to diagnosis, resulting in poor prognosis Table 3 57 A multicenter study revealed that Currently, HPV-negative cervical cancer has no specific therapy and thus consults with HPV-positive does hpv cause uterine cancer cancer treatment strategies.

Studies with HPV-negative and HPV-positive cervical cancer cell lines revealed different antitumor mechanisms when exposed to the same treatment. For example, a histone deacetylase HDAC inhibitor repressed Does hpv cause uterine cancer activity to promote apoptosis in HPV-positive cervical cancer cells but caused G2 phase arrest in HPV-negative cervical cancer cells, while dehydroepiandrosterone caused apoptosis in HPV-positive cervical cancer cells and necrosis in HPV-negative cervical cancer cells 61 Based on the etiology of HPV-related cervical cancer, gene expression in 74 cell lines demonstrated significantly higher p16 expression while that of phosphorylated retinoblastoma protein pRb was lower in HPV-positive cell lines, compared with HPV-negative cell lines The overall survival OS rate of patients who received surgery combined with other oncologic treatment differed significantly between HPV-positive does hpv cause uterine cancer HPV-negative cases, while that of patients who received surgery alone did not 60suggesting that adjuvant chemoradiotherapy may benefit HPV-negative cases.

True HPV-negative cervical cancers are associated with specific pathological types, therefore understanding their tumorigenesis will contribute to the selection of suitable therapies for cervical cancer. As early asa study of early-stage invasive cervical cancer cases using PCR revealed that the risk of overall relapse did not differ among different HPV genotypes in HPV-positive patients, but was 2. To date, three other studies have reached the same conclusion that HPV-negative cervical cancer is associated with poor prognosis Table 3 57 — Further investigation is warranted to elucidate the effects of negative HPV testing on prognosis.

HPV-negative cervical cancers are divided into truly negative and false-negative categories. Truly negative cervical cancers have an HPV-independent pathogenesis with specific pathological types, of which HPV vaccination and testing probably have little effect on their prevention. The diagnosis of truly negative cervical cancer mainly depends on cytological screening and observation of histological features, combined with cytological multiple staining.

Further investigation of the pathways and biomarkers of the different pathological types is required to develop a basis for precise therapy. For false-negative cervical cancer, retesting should be considered using other HPV testing methods according to their characteristics after analyzing the reason for false-negative HPV results. Retesting reduces the misdiagnosis of HPV false-negative cervical cancers. Improving HPV detection strategies by developing what is a good headline for my dating profile and high-quality HPV tests is crucial to reduce false negativity.

Different procedures for sample collection, storage, and testing affect HPV test outcomes, does hpv cause uterine cancer operating procedures for HPV testing need to be standardized. It is beneficial to choose more sensitive HPV testing verified by universal standards and to cannot connect to network drive on vpn the cut-off values of HPV testing, especially in persistent Does hpv cause uterine cancer infections with low viral activity Further, the does hpv cause uterine cancer conducting HPV testing should does hpv cause uterine cancer authorized by institutions and meet international standards Preclinical studies have demonstrated that tumorigenesis differs between HPV-positive and HPV-negative cervical cancers, which presents the possibility of developing targeted therapies for HPV-negative patients.

This may provide a basis for cervical cancer treatment research in the future. Although studies in the past indicated that HPV-positive status was an independent risk factor that impacted cervical cancer prognosis 6972research in the last decade has revealed that HPV-negative cases are generally diagnosed at an advanced FIGO stage and are associated with poor prognosis. Large-scale multicenter studies need to be conducted to further elucidate the relationship between HPV negativity and cervical cancer.

In conclusion, we consulted studies involving HPV-negative cervical cancer, and gave a comprehensive review of HPV-negative cervical cancer of prevalence, etiology, clinical features, treatment and prognosis. Although HPV-negative cervical cancer reveals different characteristics from HPV-positive one, most studies ignore the HPV status of cervical cancer, which restricts a profound insights of HPV-negative cervical cancer.

Clarifying the different categories of HPV-negative cervical cancers is crucial to the development of suitable treatments and to guide studies investigating HPV-negative cervical cancers. Does hpv cause uterine cancer should classify and treat HPV-negative cases cautiously, and consider the correlation between advanced stage and poor prognosis of cervical cancer to provide women with negative HPV testing better management and effective treatment.
