The estimated cervical cancer burden is over ten-fold greater in low- and middle-income countries (LMICs) than in high-income countries. This health gap is thought to be primarily due to limited access to effective screening and treatment programs for cervical pre-cancer and cancer in such settings. The World Health Organization advocates a policy of 'screen and treat' approach to cervical screening in LMICs and subsequently visual inspection of the cervix with acetic acid (VIA) or Lugo's iodine (VILI), followed by ablative cervical cryotherapy if indicated, and this policy has been implemented in many high-burden settings...

The aim of this paper is to describe the efficacy of Human Papilloma Virus (HPV) vaccines for preventing oral cancer. A systematic review of the literature was conducted to describe the state of the art about HPV vaccines for preventing oral cancer. The aspects of prevention and control of infection by administering vaccines and the diffusion of sexual education campaigns are discussed also. In recent years there has been a growing interest in HPV in dentistry, suggesting a role of such a family of viruses in the development of oral cancers as well as of the uterine cervix...

Drug delivery systems could be applied to locally treat cervical cancer, thus preventing the drawbacks of conventional therapy. In this study, anti-proliferative and anti-angiogenic effects of digoxin incorporated into poly(ε-caprolactone) implants were evaluated, aiming at the local treatment of cervical cancer. Implants were characterized, and the in vitro release profile of digoxin was demonstrated. Anti-proliferative and anti-angiogenic activities of digoxin were investigated by using chorioallantoic membrane and human cervix carcinoma (HeLa) cells, respectively...

Aberrant DNA methylation is a recognized feature in various types of human cancer, and folate has a vital role in the epigenetics of mammalian cells by supplying methyl groups for DNA methylation reactions. Fragile histidine triad (FHIT) is a tumor suppressor gene that is frequently silenced in cervical cancer (CC) and preneoplastic lesions. Promoter hypermethylation was previously observed in CC, and its epigenetic silencing has been observed at mRNA or protein levels. Changes in folate intake to modulate DNA methylation may be a mechanistic link to cancer, but this remains to be elucidated...

BACKGROUND: This is an updated version of the original Cochrane review published in 2014, Issue 4. Cervical intraepithelial neoplasia (CIN) precedes the development of invasive carcinoma of the cervix. Current treatment of CIN is quite effective, but there is morbidity for the patient related to pain, bleeding, infection, cervical stenosis and premature birth in a subsequent pregnancy. Effective treatment with medications, rather than surgery, would be beneficial. OBJECTIVES: To evaluate the effectiveness and safety of non-steroidal anti-inflammatory agents (NSAIDs), including cyclooxygenase-2 (COX-2) inhibitors, to induce regression and prevent the progression of CIN...

Second malignancies are a rare but well-defined late complication after autologous and allogeneic hematopoietic stem-cell transplantation (SCT). Solid malignancies occur in up to 15% of patients 15 years after SCT with myeloablative conditioning, with no plateau in the incidence rates. They are responsible for 5-10% of late deaths after SCT. The incidence is increased with advanced age at SCT. The major risk factors are the use of total body irradiation, which is associated with adenocarcinomas and with chronic graft-versus-host disease which is associated with squamous cell cancers...

INTRODUCTION: Smoking has been causally linked to 12 tobacco-related cancers: oral cavity and pharynx, esophagus, stomach, colon and rectum, liver, pancreas, larynx, lung, cervix, bladder, kidney, and acute myeloid leukemia. Tobacco-related cancers-related morbidity and mortality have been well described, but little is known about the prevalence of tobacco-related cancer hospitalizations and associated costs. This study estimates the annual number of tobacco-related cancer hospitalizations and their associated direct medical costs in the U...

BACKGROUND: In 2015, the second cycle of the CONCORD programme established global surveillance of cancer survival as a metric of the effectiveness of health systems and to inform global policy on cancer control. CONCORD-3 updates the worldwide surveillance of cancer survival to 2014. METHODS: CONCORD-3 includes individual records for 37·5 million patients diagnosed with cancer during the 15-year period 2000-14. Data were provided by 322 population-based cancer registries in 71 countries and territories, 47 of which provided data with 100% population coverage...

There is a dearth of existing research on the treatment of reproductive cancers among women with intellectual and developmental disabilities (IDD). This study analyzed the 2010 Healthcare Cost and Utilization Project Nationwide Inpatient Sample and compared the prevalence of reproductive cancer treatment hospitalization discharges among women with and without IDD. Discharges linked to women with IDD had higher incidences of cancer of the uterus and lower prevalence of cancer of the cervix. Moreover, discharges linked to women with IDD indicated these women were younger, had longer hospital stays, and were more likely to have public insurance coverage...

BACKGROUND: Cervical cancer is one of the most common cancers among women, with 80% of the cases occurring in developing countries. Cervical cancer is largely preventable by effective screening programs. This has not been possible with opportunistic screening and its low use in the Kingdom of Bahrain. The objective of this study was to explore the knowledge, attitudes, and practices of women attending primary care health centres for cervical cancer screening. METHODS: This was a cross-sectional study of 300 women attending primary health care centres in Bahrain...

BACKGROUND: The standard surgical procedure for early-stage cervical cancer is abdominal radical hysterectomy, including pelvic lymphadenectomy. Currently, minimally invasive surgical techniques for early cervical cancer are progressing; total laparoscopic radical hysterectomy (TLRH) is a possible alternative to abdominal surgery. In addition, sentinel node navigation surgery (SNNS), which can prevent lower limb edema, has been widely used for radical hysterectomy. MATERIALS AND METHODS: A radioisotope is injected into the uterine cervix 1 day preoperatively and surgeons carefully identify the correct sentinel lymph nodes (SLNs) to prevent picking up the cervical gamma rays during surgery...

Various methods are available for vaginoplasty, but many of them have the drawbacks including surgical complexity and postoperative pain at the donor site. We herein evaluated the outcomes of vaginoplasty using tissue-engineered biomaterial graft. This study included 16 early stage cervical cancer patients who received curative surgery in combination with radiotherapy. They underwent vaginoplasty with tissue-engineered biological material, acellular dermal matrix (ADM). After treatment, a vaginal dilator was advised to be used for 6 months to prevent contraction of vagina...

An experiment dating from the 1960s in New Zealand has eerie similarities to research begun in 1976 in India. In both cases, women with evidence of early cervical cancer or pre-cancer went untreated, despite known treatments that could have prevented their condition from worsening. This Comment on carcinoma cervix research grew out of my reading of a new book by Ronald W Jones about the New Zealand experiment. Jones, a recently retired obstetrician/gynaecologist, worked at the hospital where the controversial research took place and was a whistleblower in the case...

BACKGROUND: There remains uncertainty about the role of human papillomavirus (HPV) infection in causing small-cell neuroendocrine carcinoma (SCNC) and large-cell neuroendocrine carcinoma (LCNC) of the cervix. To clarify the role of HPV in the development of SCNC and LCNC, we conducted a systematic review and meta-analyses. METHODS: PubMed and Embase were searched to initially identify 143 articles published on or before June 1, 2017. Studies were limited to methods that tested for HPV in the cancer tissue directly to minimize misattribution...

Background:  It has been shown repeatedly that mast cells can promote or prevent cancer development and growth. If development and/or progression of a solid cancer is substantially influenced by mast cell activity, the frequencies of occurrence of solid cancers in patients with primary mast cells disorders would be expected to differ from the corresponding prevalence data in the general population. In fact, a recent study demonstrated that patients with systemic mastocytosis (i.e., a rare neoplastic variant of the primary mast cell activation disease) have increased risk for solid cancers, in particular melanoma and non-melanoma skin cancers...

Cervical and vaginal cytology, Papanicolaou test (PAP), is the most effective test for screening of preneoplastic lesions, and cervical cancer prevention. Its sensitivity goes from 50 to 98%, according to different statistics, and this variation is related to the sampling procedure. A satisfactory smear should be taken from the transformation zone, the junction between endocervix and exocervix. According to Bethesda, metaplastic and/or endocervical cells should be observed under the microscope. The traditional PAP smear includes an exo-endocervical sampling using the Ayre spatula; however, only near 50% of the smears are representative of the transformation zone...
