Article Synopsis
  • The World Health Organization aims to eliminate cervical cancer as a public health issue, but the US-Affiliated Pacific Islands currently lack accurate incidence data necessary for monitoring progress.
  • This study calculates age-standardized incidence rates of cervical cancer in the USAPI (including territories and freely associated states) from data collected between 2007 and 2020.
  • Findings indicate that from 2007 to 2020, 409 cases were diagnosed in the USAPI, with age-standardized incidence rates between 21.7 and 22.1 cases per 100,000 women, highlighting the need for focused cancer control strategies in the region.

Article Synopsis
  • - Breast cancer is the most common cancer among women worldwide, but its occurrence in the US-Affiliated Pacific Islands (USAPI) is not well understood.
  • - From 2007-2020, there were 1,118 breast cancer cases in the USAPI, with most cases (66.3%) occurring in Guam; the incidence rates were lower in USAPI compared to the US, but the rates of late-stage diagnoses were significantly higher.
  • - The findings suggest that low breast cancer incidence rates alongside higher late-stage diagnoses in the USAPI indicate potential issues with access to screening and healthcare, highlighting the need for improved cancer services in the region.

Hysterectomy protects against cervical cancer when the cervix is removed. However, measures of cervical cancer incidence often fail to exclude women with a hysterectomy from the population-at-risk denominator, underestimating and distorting disease burden. In this study, we estimated hysterectomy prevalence from the Behavioral Risk Factor Surveillance System surveys to remove the women who were not at risk of cervical cancer from the denominator and combined these estimates with the US Cancer Statistics data.

Introduction: We examined national estimates of breast, cervical, and colorectal cancer (CRC) screening test use and compared them with Healthy People 2030 national targets. Test use in 2021 was compared with prepandemic estimates.

Methods: In 2022, we used 2021 National Health Interview Survey (NHIS) data to estimate proportions of adults up to date with US Preventive Services Task Force recommendations for breast (women aged 50-74 y), cervical (women aged 21-65 y), and CRC screening (adults aged 50-75 y) across sociodemographic and health care access variables.

Background: A modeling method was developed to estimate recurrence-free survival using cancer registry survival data. This study aims to validate the modeled recurrence-free survival against "gold-standard" estimates from data collected by the National Program of Cancer Registries (NPCR) Patient-Centered Outcomes Research (PCOR) project.

Methods: We compared 5-year metastatic recurrence-free survival using modeling and empirical estimates from the PCOR project that collected disease-free status, tumor progression and recurrence for colorectal and female breast cancer cases diagnosed in 2011 in 5 U.

The annual direct medical cost attributable to human papillomavirus (HPV) in the United States over the period 2004-2007 was estimated at $9.36 billion in 2012 (updated to 2020 dollars). The purpose of this report was to update that estimate to account for the impact of HPV vaccination on HPV-attributable disease, reductions in the frequency of cervical cancer screening, and new data on the cost per case of treating HPV-attributable cancers.

Article Synopsis
  • Scrotal squamous cell carcinomas (SCCs) are rare cancers previously thought not to be linked to HPV, but recent studies show evidence of HPV presence in these tumors.
  • A study examined scrotal SCC cases from cancer registries using tissue samples and HPV testing, confirming the morphology of the tumors.
  • Out of five identified cases, two were HPV-positive (HPV16) with p16 overexpression, suggesting a potential link between HPV and the development of scrotal SCC.

Purpose: Women exposed to diethylstilbestrol (DES) in utero were at elevated risk of clear-cell adenocarcinoma of the vagina and cervix (CCA) as young women. Previous research suggested that this elevated risk of CCA may persist into adulthood. We extended a published analysis to measure CCA risk as these women aged.

Introduction: Limited evidence exists on the comparative effectiveness of local treatments for prostate cancer (PCa) due to the lack of generalizability. Using granular national data, we sought to examine the association between radical prostatectomy (RP) and intensity-modulated radiation therapy (IMRT) treatment and survival.

Methods: Records were abstracted for localized PCa cases diagnosed in 2004 across seven state registries to identify patients undergoing RP (n=3019) or IMRT (n=667).

Background: The National Comprehensive Cancer Network (NCCN) guidelines have recommended tailored chemotherapy for stage III high-risk (T4 and/or N2) and low-risk (T1-T3 and N1) colon cancer since 2018. Studies have investigated the effect of relative dose intensity (RDI) of FOLFOX on stage III colon cancer survival, however, none has performed a stratified analysis by risk profiles. This study aims to identify the FOLFOX optimal RDI for high-risk and low-risk stage III colon cancer patients.

Article Synopsis
  • US cancer registries are used to monitor the prevalence of HPV types in cervical cancers, comparing data before and after the HPV vaccine was introduced.
  • The study analyzed archived tissue samples from both prevaccine (1993-2005) and postvaccine (2014-2015) periods across multiple states to assess HPV prevalence in high-grade cervical precancers and invasive cervical cancers.
  • The results showed no significant difference in HPV-type prevalence between the two time periods, possibly due to low vaccination rates and a small number of cases in the postvaccine study; ongoing monitoring remains crucial for evaluating the vaccine's effectiveness.
