MedicalResearch.com Interview with: Kalyani Sonawane, PhD Assistant Professor of Management, Policy and Community Health UTHealth School of Public Health in Houston MedicalResearch.com: What is the background for this study? Response: Safety concern regarding the HPV vaccine is one of the most significant barriers to vaccination. Our objective was to determine how many US adolescents did not initiate the HPV vaccine during 2015-2018 because their parents had concerns regarding the vaccine’s safety. We also analyzed vaccine adverse event reporting data, in parallel, to understand if the public sentiment of HPV vaccine safety is in alignment with evidence from the vaccine safety surveillance system.  (more…)

MedicalResearch.com Interview with: Helen Trottier Ph.D Assistant Professor, Department of Social and Preventive Medicine, Researcher, CHU Sainte-Justine Research Center Université de Montréal Montréal, Québec, Canada MedicalResearch.com: What is the background for this study? Response: We know that HPV infection can have serious consequences such as the development of cancerous lesions in the cervix. HPV infection is also very prevalent in young women of childbearing age but the possible consequences of HPV in pregnancy have been poorly studied. Some population registers around the world have shown a reduction in the risk of preterm birth with HPV mass vaccination, but we must be careful with this kind of ecological correlation. We have set up a large cohort study in pregnant women to study the association between HPV in pregnancy and preterm birth by targeting certain HPV genotypes and the duration of the infection. (more…)

MedicalResearch.com Interview with: Yuehan (Jenny) Zhang, ScM PhD Candidate in Cancer Epidemiology Johns Hopkins Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? Response: Human Papillomavirus (HPV) is the most common sexually transmitted infectious virus worldwide. Oral HPV infection has resulted in a continual increase in the incidence of oropharynx cancer over the past two decades in the US. New HPV infections are preventable with vaccines, which first entered use in the US in 2006. (more…)

MedicalResearch.com Interview with: Mai Takahashi MD MPH Mount Sinai Beth Israel - Resident Physician New York, New York MedicalResearch.com: What is the background for this study? Response: The incidence of head and neck cancer had been significantly increasing in North America and Europe driven by Human Papillomavirus-related cancer (HPV OPC) which account for more than 60% of total oropharyngeal cancer cases. Compared to environmentally related oropharyngeal cancer, the HPV OPC patient population is generally younger and has a much better prognosis. However, they will suffer from long-term deteriorations in quality of life (QoL) and the declines associated with treatment intensity. Hence multiple studies have focused on de-intensification therapy with reduced dose chemoradiotherapy (CRT).  (more…)

MedicalResearch.com Interview with: Michelle M. Chen, MD/MHS Clinical Lecturer Department of Otolaryngology-Head and Neck Surgery University of Michigan MedicalResearch.com: What is the background for this study? Response: HPV is the most common sexually transmitted infection in the United States and associated with several malignancies including oropharyngeal, cervical, vaginal, vulvar, penile, and anal cancers. In 2020, the FDA expanded the indications for HPV vaccination to include the prevention of oropharyngeal cancer, which is the most common HPV-associated malignancy and about 80% of oropharyngeal cancer patients are male. HPV vaccination rates are closely tracked for adolescents but less is known about vaccination rates for young adults. The goal of our study was to understand HPV vaccinations for young adult men and women, ages 18-21.  (more…)

MedicalResearch.com Interview with: Brianna M. Jones, MD Icahn School of Medicine at Mount Sinai New York, NY MedicalResearch.com: What is the background for this study? Response: Oral tongue cancer has traditionally been a diagnosis associated with older age and habitual tobacco or alcohol use. However, in the past few decades there has been a disproportionate increase in oral tongue cancer in young patients, particularly in those without a prior history of significant alcohol or tobacco use. In the literature, these young patients without traditional risk factors seem to represent a distinct clinical entity with worse oncologic outcomes. The purpose of this study was to compare young patients (age ≤45) to older patients (>45) with oral tongue squamous cell carcinoma (OTSCC) without habitual smoking or drinking history.  (more…)

Response: The efficacy and effectiveness of quadrivalent HPV (qHPV) vaccine protecting against HPV infection, genital warts and high-grade precancerous cervical lesions have been shown. However, there is lack of population-based studies in examining the association between HPV vaccine and invasive cervical cancer on individual level.  (more…)

MedicalResearch.com Interview with: Ashish Deshmukh, PhD, MPH Assistant Professor UTHealth School of Public Health Houston MedicalResearch.com: What is the background for this study? Response: Anal cancer is one of the six human papillomavirus associated cancers.  Rates of anal cancer are increasing in the US, but no prior study quantified the contemporary trends (i.e., increase in rates over time) in anal cancer incidence. It was unknown whether the rise is real or driven by increased screening in some high-risk populations. Incidence trends according to age and stage at diagnosis was also never comprehensively studied. Furthermore, it was unknown whether the rise in incidence has led to a rise in mortality. Our objective was to answer these questions. (more…)

MedicalResearch.com Interview with: Rachel L. Winer, PhD Professor Department of Epidemiology School of Public Health HPV Research Group University of Washington Seattle, WARachel L. Winer, PhD Professor Department of Epidemiology School of Public Health HPV Research Group University of Washington Seattle, WA  MedicalResearch.com: What is the background for this study? Response: In the U.S., 25% of women do not receive recommended cervical cancer screening. Increasing screening participation is a high priority, because over half of the 12,000 cervical cancers diagnosed each year in the U.S. are in women who are underscreened. Currently available options for cervical cancer screening in the U.S. include Pap testing or HPV testing, either alone or in combination. HPV self-sampling is an emerging option for screening because HPV tests – unlike Pap tests – can be performed on either clinician- or self-collected samples, with similar accuracy. Internationally, several countries (including Australia and the Netherlands) include HPV self-sampling as a cervical cancer screening option for underscreened women.  (more…)

MedicalResearch.com Interview with: Dr. Ashish A. Deshmukh UT Health School of Public Health Houston MedicalResearch.com: What is the background for this study? Response: The HPV vaccination is recommended for females and males for prevention of 6 cancers (cervical, oropharyngeal, anal, penile, vaginal, and vulvar). Nearly 43,000 HPV-associated cancer cases are diagnosed every year in the US. Yet, it is extremely unfortunate and something that continues to bother us that HPV vaccination coverage remains low (50% in 2018) in the US and completion rate is nearly 5% lower in boys. Different from some industrialized nations where vaccination policy is school-based, vaccination policy in the US is clinic-based and parents are generally responsible for making vaccination decisions for their children. Generally, there are two main factors that drive parents’ decision-making: (1) how much knowledge they have of HPV and (2) recommendation from a healthcare professional. We analyzed the National Cancer Institute’s Health Information National Trend Survey (HINTS) of over 6000 participants focusing on their knowledge of HPV and HPV vaccination and whether participants received any vaccination recommendation from their health care provider.  (more…)
Author Interviews, Cancer Research, HPV, OBGYNE / 15.08.2019

MedicalResearch.com Interview with: Marc Eloit, D.V.M, Ph.D. Pathogen Discovery Laboratory, Biology of Infection Unit, Institut Pasteur Paris, France MedicalResearch.com: What is the background for this study? Response: Human papillomaviruses (HPV) are responsible for >99% of cervical cancers. Currently, cervical cancer screening either focuses on testing for the presence of HPV or identifying abnormal cervical cells with cytology (Pap test). However, molecular diagnostic tests based on the detection of viral DNA or RNA have low positive predictive values for the identification of cancer or precancerous lesions, and analysis of cervical cells with the Pap test, even when combined with molecular detection of high-risk HPV, results in a significant number of unnecessary colposcopies. We have developed HPV RNA-Seq, a new “two-for-one” molecular diagnostic test that not only detects the type of HPV, but also identifies precancerous markers. This test is therefore designed to diagnose the riskiest forms of HPV infection, provide rapid results at moderate cost, and helps avoiding unnecessary diagnostic procedures. HPV RNA-Seq is based on the dual combination of multiplexed reverse transcription PCR (RT-PCR) and next-generation sequencing (NGS). RT-PCR is a sensitive way to detect small amounts of RNA, the genetic material that reflects the activity of the HPV genes, and NGS finely characterizes the amplified viral sequences. This enables detection of up to 16 high-risk or putative high-risk HPV in a sample as well as the presence of precancerous markers. (more…)

MedicalResearch.com Interview with: “Syringe and Vaccine” by NIAID is licensed under CC BY 2.0Ali Moghtaderi PhD MBA Assistant Research Professor and Avi Dor PhD Professor of Health Policy and Economics Milken Institute School of Public Health George Washington University MedicalResearch.com: What is the background for this study? Response: In this study, we investigate the effect of Human Papillomavirus (HPV) vaccination on participation in Pap test, which is one of the most effective cancer screening interventions. Cervical cancers are causally linked to HPV infections. The Pap test is a diagnostic procedure for early detection of cervical cancer. HPV vaccination provides partial protection against cervical cancer, and the Pap test is strongly recommended for women 21 to 65 years of age even after vaccination. If vaccination leads to a reduction in testing participation, it could contribute to greater incidence and severity of cervical cancer. Note that we focus on relatively older women (age 22 or older) who were not vaccinated at younger ages.  (more…)
Author Interviews, Dermatology, HPV, Yale / 20.06.2019

MedicalResearch.com Interview with: Richard J. Antaya, MD, FAAD, FAAP Professor, Dermatology and Pediatrics Yale University School of Medicine  MedicalResearch.com: What is the background for this study? Response: Localized hyperthermia has been reported to hasten the resolution of warts and treat both benign and malignant neoplasms. Numerous clinical studies employing various methods to increase the cutaneous surface temperature, including: infrared radiation, radiofrequency, Nd:YAG laser, moxibustion, warm water immersion, ultrasound, and exothermic heat patches, have all yielded positive results. We published a proof-of-concept, open-label trial, representing the largest experience to date employing chemical reaction induced exothermic heat patches for the treatment of warts. Localized hyperthermia from all sources currently has a low level of evidence and strength of recommendation because of the lack of well-designed, sufficiently powered studies.  (more…)

MedicalResearch.com Interview with: Lael S. Reinstatler, MD, MPH. PGY 4 Urology Residency Dartmouth Hitchcock MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Human Papillomavirus is an oncogenic virus associated with other genitourinary cancers including penile cancer. HPV is detectable in urine and in urethral swabs and it interacts with stratified squamous epithelium which lines the majority of the genitourinary tract. Prior research has identified HPV in bladder tumors but detection methods are inconsistent. In this study, we looked for an association with HPV serology (indicating prior HPV systemic exposure) and bladder cancer. (more…)

Author Interviews, BMJ, Cancer Research, HPV, OBGYNE, Sexual Health, Vaccine Studies / 05.04.2019

MedicalResearch.com Interview with: Dr. Tim Palmer Honorary Senior Lecturer Department of Pathology University of Edinburgh Edinburgh, UK  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: High risk HPV infection is the obligate cause of between 70 and 90% of cervical cancers, depending upon the country. The development of vaccines against the commonest hr-HPV types has the potential to reduce the burden of cervical cancer, especially in low and middle income countries that cannot afford screening programmes. Cervical cancer affects predominantly women in their 30s and is a major public health issue even in countries with well-established screening programmes. Scotland has had a successful immunisation programme since 2008, and women immunised at age 12 to13 have been screened since 2015. We can therefore demonstrate the effect of hr-HPV immunisation on the pre-invasive stages of cervical cancer. (more…)

MedicalResearch.com Interview with: Diane Harper, M.D., M.P.H., M.S. Professor of Family Medicine and Obstetrics and Gynecology Senior Associate Director, Michigan Institute for Clinical and Health Research Physician Director for Community Outreach, Engagement and Health Disparities, Rogel Cancer Center Michigan Medicine  MedicalResearch.com: What is the background for this study? Response: There is no current cure for women with HPV infection that has progressed to CIN 2/3 disease. The only treatment is for the diseased cervix, and does not eliminate the risk of another CIN 2/3 from the HPV infection 15-20 years later. This vaccine is made from a live virus that has 3 genes inserted:  human cytokine IL-2, and modified forms of HPV 16 E6 and E7 proteins. When the vaccine is injected subcutaneously, the proteins for HPV 16/E6 and E7 and the cytokine LI-2 proteins are made. These proteins trigger the immune response.  This is very different form imiquimod which is topical and not specific for HPV. (more…)

MedicalResearch.com Interview with: Lisa T. Wigfall, PhD, MCHES(R) Assistant Professor, Health and Kinesiology Texas A&M MedicalResearch.com: What is the background for this study? Response: Human papilloma virus (or HPV) is a very common sexually transmitted infection that can cause some types of cancer. These include anal, cervical, oral, penile, vaginal, and vulvar cancers. Some people such as people who are HIV-positive and men who have sex with men have a greater risk for developing HPV-associated cancers. The risk of developing anal cancer is significantly higher for men who have sex with men who are also HIV-positive. Our study included adults who were at risk for becoming HIV-positive, which included having unprotected anal sex. (more…)

MedicalResearch.com Interview with: Matejka Rebolj, PhD King’s College London, London, UK   Professor Henry Kitchener, MD FRCOG FRCS University of Manchester, Manchester, UK   MedicalResearch.com: What is the background for this study? Response: We now have reliable and affordable technologies to detect human papillomavirus (HPV), a virus which is universally accepted as the cause of cervical cancer. Various large trials confirmed that cervical screening could be improved by replacing the smear (cytology) test that has been in use for decades, with HPV testing. Many countries are now making the switch. In England, this is planned for the end of 2019. To test how to run HPV testing within the English National Health Service, a pilot was initiated in 2013 in six screening laboratories. We also wanted to determine whether the encouraging findings from the trials could be translated to everyday practice. This is important not only because we will be using different HPV tests, but also because women undergoing screening in trials are much more selected than those who are invited to population-based screening.  (more…)

MedicalResearch.com Interview with: Prof. J. (Hans) Berkhof PhD Vrije Universiteit Amsterdam  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In most countries, the Pap test is used for cervical cancer screening but recently several countries have switched from Pap testing to HPV testing. Like the Pap test, the HPV test requires a cervical sample to be taken by a clinician. Vaginal self-sampling is also used, but only in underscreened women. We know that self-sampling increases screening participation in underscreened women and it is likely that many women that attend screening also prefer self-sampling if it had been offered to them. We studied whether an HPV self-sampling test is an accurate alternative to a regular HPV test in women invited for routine screening. We randomized about 14,000 women, invited for screening, to self-sampling or clinician-sampling. Women with a positive HPV test result also received the other HPV test. We found that the HPV self-sampling test yielded similar performance as the regular HPV test for detection of cervical pre-cancerous lesions (CIN3 and CIN2).  (more…)

MedicalResearch.com Interview with: Anna Beavis, MD, MPH Assistant Professor The Kelly Gynecologic Oncology Service Department of Gynecology and Obstetrics Johns Hopkins Medicine Baltimore, MD 21287-128 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to look at reasons parents don’t vaccinate their children against HPV, including how those reasons have changed over time from 2010-2016 and how those reasons are different between boys and girls in the most recent data from 2016. We used a nationwide dataset which is publically available from the CDC (Centers for Disease Control) – the National Immunization Survey-Teen, or NIS-Teen - which surveys parents of teens ages 13-17 years old every year to determine rates of all recommended vaccinations. In parents who report that they don’t intend to vaccinate their child against HPV , the survey asks parents why. We found that from 2010 to 2016, the percentage of parents reporting concerns about their child not being sexually active yet went down significantly for both boys and girls. Also, in boys specifically, parents reported male gender as a less common reason for not vaccinating. For both boys and girls, we found that concerns about safety and side effects, necessity, and lack of knowledge about the vaccine were common reasons for not planning to vaccinate.  Also, 10% of parents of girls vs. 20% of parents of boys reporting never having a provider recommendation for the vaccine as their primary reason for not vaccinating. These results may reflect the growing public understanding of the HPV vaccine as a vaccine which is best given before exposure, so before initiation of sexual activity between the ages of 11 and 12, and that it is recommended for both boys and girls. Also, over 80% of people will have an HPV infection in their lifetime, so everyone should get vaccinated regardless of anticipated sexual activity. Additionally, providers should focus their counseling and recommendation on improving knowledge about the HPV vaccine, including its decade-long track record of safety and necessity.    (more…)

MedicalResearch.com Interview with: Megan Clarke, PhD, MHS Cancer Prevention Fellow Clinical Genetics Branch Division of Cancer Epidemiology & Genetics National Cancer Institute Rockville, MD 20892  MedicalResearch.com: What is the background for this study?
  • Infection with high-risk human papillomavirus (hrHPV) is the primary cause of cervical cancer. While hrHPV infection is common, most infections are benign and clear on their own without causing cervical cancer. However, some women develop persistent hrHPV infections and are at risk for cervical cancer and its precursors (i.e., precancer).
  • The United States Preventative Services Task Force recommends screening every 3 years with cervical cytology (i.e. Pap) alone, every 5 years with hrHPV testing alone, or with a combination of hrHPV testing and cytology (co-testing) for women aged 30 to 65 years.
  • Screening with hrHPV testing is highly sensitive for detecting cervical precancer but requires additional triage tests to identify HPV-positive women at high-risk of developing cancer who should undergo colposcopy (visualization of the cervix) and biopsy from those at low-risk who can be safely monitored.
  • Currently, Pap cytology is recommended as a triage test for women testing HPV-positive, but this approach requires frequent re-testing at short intervals because the risk of cervical precancer is not low enough in HPV-positive women who test cytology negative to provide long-term reassurance against future risk. In most settings, women who test HPV-positive, cytology-negative are referred to repeat screening within one year.
  • The p16/Ki-67 dual stain assay is a molecular test that measures two specific proteins, p16 that is strongly linked with hrHPV infection, and Ki-67, a marker of cell proliferation that is common in precancers and cancers.
  • Studies have shown that the dual stain test has greater accuracy for detecting cervical precancers in HPV-positive women compared with cytology.
  • In order to determine the optimal screening intervals for the dual stain test, long-term prospective studies are needed to determine how long HPV-positive women who test dual stain negative can be safely reassured of a low precancer risk.

MedicalResearch.com Interview with: Brandon Brown, MPH, PhD Associate Professor Center for Healthy Communities Department of Social Medicine, Population and Public Health UCR School of Medicine Riverside, CA MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The authors have been working in Lima, Peru on HIV-related projects for over 17 years. This particular study arose out of interest from our main community collaborator and the only gay men’s health NGO in Lima, Epicentro Salud (http://epicentro.org.pe/index.php/en/). The NGO noticed that one of the main health issues among their clients was genital warts. When we learned this, we applied for funding through the Merck Investigator Initiated Studies Program to conduct a study examining the link between genital warts and incident HIV infection. Although most studies have shown a general link between HPV and HIV co-infection, our findings illustrate the strong relationship between individual HPV types and HIV infection. Specifically, individuals in our study with any HPV type, more than one HPV type, or high-risk HPV were more likely to acquire HIV. (more…)
Author Interviews, Cancer Research, HPV, UCLA / 28.09.2018

MedicalResearch.com Interview with: Manon Eckhardt, PhD Gladstone Institutes The Quantitative Biosciences Institute University of California San Francisco  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Infection with Human Papillomavirus (HPV) causes 5% of all cancers worldwide, including cervical cancer and an increasing number of head and neck cancers. Most cancers are caused by mutations in genes, leading to the production of malfunctioning proteins that result in unconstrained cell division. However, certain viruses like HPV can cause cancer without introducing mutations. In this study, we compared cancers of the same type (i.e. head and neck) that are caused by either mutation or virus infection to identify important processes that are dysregulated in both subsets. We hypothesized that identifying which proteins the virus binds can lead the way to prioritize which of the proteins and cellular processes (pathways) that are affected in cancer cells are most important. To do this, we identified the complete set of human proteins that interact with HPV. We next determined genes that were more frequently mutated in non-viral cancers, and combined both data sets. The proteins we find to be both binding to HPV and mutated in non-viral cancers will be potential targets for new, more specific drug development, and help better understand the development of head and neck cancer. From the many pathways we identified in this study, we highlighted two pathways with further mechanistic studies: the oxidative stress response, which helps cancer cells survive, as well as a pathway that allows the cancer to spread to other parts of the body.

MedicalResearch.com Interview with: Dr. Jeffrey Rapaport MD, PA Emeritus head of Dermatology Teaneck's Holy Name Hospital. Dr. Rapaport discusess a case recently reported in JAMA: In 2016: A 97-year-old female patient was suffering from multiple squamous cell carcinomas varying from small to incredibly large in size on both of her legs. She was injected with the HPV vaccine commonly known as Gardasil, which is also used to treat warts and oral papilloma. She was first injected in her arm, and then after a period of six weeks, the vaccine was directly injected into her tumors. It was observed that this treatment eventually killed off almost all the tumors on her legs. According to recent press coverage, she is now looking forward to celebrating her 100th birthday in fall 2018. MedicalResearch.com: What is the background for this study?Is HPV thought be a trigger for some cutaneous squamous cell carcinomas? Response: The link between skin cancers and HPV vaccinations has normally been investigated in patients who have received organ transplants. Due to the immune-suppressant drugs these patients must take, it is incredibly common to find cases of skin cancer in patients who have undergone transplants. The relaxed immune system, which would normally eliminate cancers caused by the HPV virus, would open the floodgates for multiple skin tumors to emerge. In this case of the 97 year old, I would assume her immune system was healthy. There is, however, growing evidence that receiving multiple vaccines for the HPV virus is necessary even in patients with healthy immune systems. So, regardless of immune health, I believe we need to expand the frequency of the HPV vaccine, even beyond the current three-tiered system for women below 26 and men below 21. (more…)

MedicalResearch.com Interview with: Eric Adjei PhD, MA Saint Louis University Center for Health Outcomes Research (SLUCOR) St. Louis, Missouri  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Survivors of head and neck cancer (HNC) develop second primary cancers (SPCs) at a higher rate than most common cancers. This is concerning because the number of HNC survivors are increasing due to advancements in treatment and technology. Patients whose head and neck cancer was caused by smoking and alcohol are different than those whose HNC were caused by human papillomavirus (HPV). We therefore used data from 2000-2014 National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) 18 database to examine if the incidence and the type of SPC that patients with smoking-related HNC develop were different from those from HPV-related head and neck cancer. First, independent of group of HNC (HPV-related or not), we found that SPCs among survivors of head and neck cancer were high, with about 1-in-8 patients developing an SPC. Additionally, irrespective of whether the index . head and neck cancer was from smoking-related or HPV-related, the majority of SPCs were second malignancies in head and neck region (e.g. tongue, gum, mouth floor etc), lung and esophagus. However, we observed different incidence rates between the two groups. Patients with smoking-related head and neck cancer developed SPCs at a higher rate (14%) than those with HPV-related HNC (10%).

What are the main findings? Response: HPV is known to be the cause of 99% of cervcial cancers. In this study, we compared the routine screening test for cervical cancer, Pap test, to HPV testing. We found that by using HPV testing, women were significantly more likely to have cervical pre-cancers detected earlier. In addition, women with negative HPV tests were significantly less likely to have pre-cancers 48 months later. (more…)

MedicalResearch.com Interview with:

Dr. Christina Lee Chung, MD Associate Professor Department of Dermatology Drexel University

MedicalResearch.com:  What is the background for this study?  What are the main findings?

Response: In early 2016, five years after the inception of our specialty medical-surgical transplant dermatology center, we realized our nonwhite transplant patients were developing skin cancer at higher rates and found interesting trends. These data were published in a previous manuscript. One of the more striking findings was that these patients were developing a high proportion of skin cancer in non-sun-exposed areas such as the genital region. There are no standard guidelines regarding genital skin evaluation and it is unclear how often it is performed in any capacity amongst dermatologists, including practitioners in our center, quite frankly. Our group was concerned that we could be missing skin cancers in this “hidden” area in our high-risk organ transplant population so we launched a quality improvement initiative that incorporated thorough genital skin evaluation as a standard part of post-transplant skin cancer screening.   

Fifteen months after we started this modified screening process, we decided to evaluate the results. To account for any variation in examination, we looked at the findings of a single practitioner. We found that genital lesions are common in the transplant population and include high rates of genital warts and skin cancer. However, patient awareness of the presence of genital lesions was alarmingly low. Nonwhite transplant patients, Black transplant recipients in particular, were disproportionately affected by both genital warts and genital skin cancer in our cohort. Similar to cervical cancer, high-risk HPV types were closely associated with genital squamous cell carcinoma development in our transplant population. (more…)

MedicalResearch.com Interview with: Dr Miranda M Fidler, PhD Section of Cancer Surveillance International Agency for Research on Cancer Lyon, France  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The burden of cancer among young adults has been rarely studied in depth. To our knowledge, we describe for the first time the scale and profile of cancer incidence and mortality worldwide among 20-39 year-olds, highlighting major patterns by age, sex, development level, and geographic region. Although cancer is less frequent than that observed at older ages, its impact remains considerable because these individuals have a large proportion of their expected lifespans remaining, contribute substantially to the economy, and play a major role in caring for their families. Worldwide, almost 1 million new cases of cancer and 400 000 cancer-related deaths occurred among young adults aged 20–39 years in 2012. Overall, the most common cancer types in terms of new cases were female breast cancer, cervical cancer, thyroid cancer, leukemia, and colorectal cancer, and the most common types of cancer-related deaths were those due to female breast cancer, liver cancer, leukemia, and cervical cancer. The burden was disproportionately greater among women, with an estimated 633 000 new cancer cases (65% of all new cancer cases in that age group) and 194 000 cancer-related deaths (54% of all cancer-related deaths in that age group) in 2012.
