Oropharyngeal, cervical, vulvar, and anal cancers share a common risk factor of HPV infection. HPV vaccination is currently recommended at age 11 or 12 to prevent new HPV infections for all genders with catch-up vaccination recommened up to age 26. Despite the known effectiveness of HPV vaccination to prevent HPV-related cancer, there is continued low uptake in the United States; only 40% of eligible persons were vaccinated in 2018, though rates are 70% among teenagers. Current American Cancer Society cancer screening guidelines recommend cervical cancer screening, but do not have specific recommendations for screening for other HPV-related cancers. Oropharyngeal cancer precursors have yet to be identified, and there are currently no routine screening tests for oropharyngeal cancer recommended by the U.S.  https://www.selleckchem.com/products/z-vad(oh)-fmk.html  Preventive Services Task Force. The U.S. Preventive Services Task Force and American Cancer Society recommend cervical cancer screening for women at average risk up to age 65, and screening guidelines do not currently differ by HPV vaccination status. Primary HPV DNA testing was first approved for cervical cancer screening in 2016 and was shown to be superior for cervical cancer prevention. Vulvar and anal cancer precursors have been identified, but optimal screening remains unclear. Examination of the anal canal and perianus is best performed by trained clinicians using high-resolution anoscopy, and effectiveness of using high-resolution anoscopy to detect and treat anal high-grade squamous intraepithelial lesions to prevent cancer is actively being researched. Current multistep approaches to control HPV-related malignancies include HPV vaccination coupled with cervical cancer screening or surveillance for oropharyngeal, vulvar, and anal cancers.Cancer is an increasing and significant problem for both high- and low- and middle-income countries. Basic, translational, and clinical research efforts have been instrumental in generating the outstanding improvements we have witnessed over the last few decades, answering important questions, and improving patient outcomes. Arguably, a substantial portion of currently ongoing research is sponsored by the pharmaceutical industy and specifically addresses questions under industry interests, most of which apply to high-income countries, leaving behind problems related to the much larger and underserved population of patients with cancer in low- and middle-income countries. In this scenario, discussing independent academic research is an important challenge, particularly for these countries. Although different countries and institutions face different problems while establishing independent research agendas, some generalizable barriers can be identified. A solid regulatory and ethical framework, a strong and sustainable technical supporting infrastructure, and motivated and experienced investigators are all paramount to build a viable and productive academic research program. Securing funding for research, although not the only hurdle, is certainly one of the most basic hurdles to overcome. Noticeably, and as an added impediment, public and governmental support for cancer research has been decreasing in high-income countries and is almost nonexistent in the rest of the world. We propose an initial careful diagnostic assessment of the research resource scenario of each institution/country and adjustment of the strategic development plan according to four different research resource restriction levels. Although not necessarily applicable to all situations, this model can be helpful if adjusted to each local or regional situation.Avoidable differences in the care and outcomes of patients with cancer (i.e., cancer care disparities) emerge or worsen with discoveries of new, more effective approaches to cancer diagnosis and treatment. The rapidly expanding use of immunotherapy for many different cancers across the spectrum from late to early stages has, predictably, been followed by emerging evidence of disparities in access to these highly effective but expensive treatments. The danger that these new treatments will further widen preexisting cancer care and outcome disparities requires urgent corrective intervention. Using a multilevel etiologic framework that categorizes the targets of intervention at the individual, provider, health care system, and social policy levels, we discuss options for a comprehensive approach to prevent and, where necessary, eliminate disparities in access to the clinical trials that are defining the optimal use of immunotherapy for cancer, as well as its safe use in routine care among appropriately diverse populations. We make the case that, contrary to the traditional focus on the individual level in descriptive reports of health care disparities, there is sequentially greater leverage at the provider, health care system, and social policy levels to overcome the challenge of cancer care and outcomes disparities, including access to immunotherapy. We also cite examples of effective government-sponsored and policy-level interventions, such as the National Cancer Institute Minority-Underserved Community Oncology Research Program and the Affordable Care Act, that have expanded clinical trial access and access to high-quality cancer care in general.
  Biopsy to achieve tissue diagnosis (TD) of hepatocellular carcinoma (HCC) risks needle tract seeding. With chest wall and peritoneal recurrences reported, TD could worsen cancer outcomes. We investigated HCC outcomes after TD compared to clinical diagnosis (CD), hypothesizing that TD adversely affects overall survival (OS).
 
  The National Cancer Database (NCDB) Participant User File for liver cancer was reviewed, including patients with nonmetastatic HCC treated with major hepatectomy or transplantation. Clinical diagnosis patients were matched 11 to TD patients per propensity score. Survival was examined in the unmatched and matched cohorts.
 
  Of 172283 cases, 16366 met inclusion criteria. Mean age was 60.8years, 12100 (73.9%) were male, and 48.4% of patients received hepatectomies. Clinical diagnosis occurred in 70.4% of cases, and 29.6% underwent TD. Cox regression confirmed the diagnostic method as an independent predictor of OS in addition to age, Charlson-Deyo score, grade, delay of surgery, lymphovascular invasion, nodal stage, and procedure type, favoring transplantation over hepatectomy.
