RESUMO

BACKGROUND: Adequate social support for older adults is necessary to maintain quality of life and reduce mortality and morbidity. However, little is known regarding the social support needs of older adults with cancer. The objective of the current study was to examine social support needs, specifically the unmet needs, among older adults with cancer. METHODS: Medicare beneficiaries (those aged ≥65 years) with cancer were identified from the University of Alabama at Birmingham Health System Cancer Community Network. Social support needs were assessed using a modified version of the Medical Outcomes Study Social Support Survey. The authors defined an "unmet need" if participants reported having some/a little/never availability of support and requiring support for that need. RESULTS: Of the 1460 participants in the current study, the average age was 74 years (standard deviation, 5.8 years). Approximately two-thirds of participants (986 participants; 67.5%) reported having at least 1 social support need, with the highest needs noted in the emotional (49.5%) and physical (47.4%) support subdomains. Of those individuals with a support need, approximately 45% had at least 1 unmet need, with the greatest percentages noted in the medical (39%) and informational (36%) subdomains. Multivariable analyses demonstrated that participants who were nonwhite, were divorced or never married, or had a high symptom burden were at greatest risk of having unmet social support needs across subdomains. CONCLUSIONS: In this population of older adults with cancer, the authors found high levels of unmet social support needs, particularly in the medical and informational support subdomains. Participants who were nonwhite, were divorced or never married, or had a high symptom burden were found to be at greatest risk of having unmet needs.

RESUMO

BACKGROUND: There is increasing evidence that radiation therapy (RT) can be omitted for select older patients who are compliant with hormonal blockade, but there is no recent claim-based analysis for determining patterns of care and guiding possible treatment recommendations. METHODS: Medicare beneficiaries who were 65 years old or older and were diagnosed with breast cancer at 1 of 12 cancer centers affiliated with an academic center in the southeastern United States were analyzed. Stage 0 or I patients treated with lumpectomy from 2012 to 2014 were identified. Patient, treatment, and center characteristics were analyzed for the utilization of RT. RESULTS: Among 800 women treated with lumpectomy, 64% received adjuvant radiation. The median age was 74 years. The omission of RT was more likely in older patients, stage 0 patients, and patients with more comorbidities (P < .01). Hormonal blockade was used in 41% of the patients who did not receive RT. The utilization of hormonal blockade with the omission of RT was more likely in patients with fewer comorbidities (P < .01). CONCLUSIONS: In an older cohort of patients who otherwise would have qualified for the omission of radiation, two-thirds were treated with radiation. Future guideline recommendations should address omission in the context of hormonal blockade compliance because only 41% of the patients used hormonal blockade when radiation was not delivered.

RESUMO

OBJECTIVE: The purpose of this study was to describe distressed and underprepared family caregiver's use of and interest in formal support services (eg, professional counseling, education, organizational assistance). METHOD: Cross-sectional mail survey conducted in communities of 8 cancer centers in Tennessee, Alabama, and Florida (response rate: 42%). Family caregivers of Medicare beneficiaries with pancreatic, lung, brain, ovarian, head and neck, hematologic, and stage IV cancers reported support service use and completed validated measures of depression, anxiety, burden, preparedness, and health. RESULTS: Caregivers (n = 294) were on average age 65 years and mostly female (73%), White (91%), and care recipients' spouse/partner (60%); patients averaged 75 years were majority male (54%) with lung cancer (39%). Thirty-two percent of caregivers reported accessing services while 28% were "mostly" or "extremely" interested. Thirty-five percent of caregivers with high depressive symptoms (n = 122), 33% with high anxiety symptoms (n = 100), and 25% of those in the lowest quartile of preparedness (n = 77) accessed services. Thirty-eight percent of those with high depressive symptoms, 47% with high anxiety symptoms, and 36% in the lowest quartile of preparedness were "mostly" or "extremely" interested in receiving services. Being interested in support services was significantly associated with being a minority, shorter durations of caregiving, and with higher stress burden. CONCLUSIONS: A large proportion of family caregivers, including those experiencing depression and anxiety symptoms and who were underprepared, are not using formal support services but have a strong interest in services. Strategies to increase service use may include targeting distressed caregivers early in their caregiving experience.

RESUMO

CONTEXT: Respecting Choices is an evidence-based model of facilitating advance care planning (ACP) conversations between health-care professionals and patients. However, the effectiveness of whether lay patient navigators can successfully initiate Respecting Choices ACP conversations is unknown. As part of a large demonstration project (Patient Care Connect [PCC]), a cohort of lay patient navigators underwent Respecting Choices training and were tasked to initiate ACP conversations with Medicare beneficiaries diagnosed with cancer. OBJECTIVES: This article explores PCC lay navigators' perceived barriers and facilitators in initiating Respecting Choices ACP conversations with older patients with cancer in order to inform implementation enhancements to lay navigator-facilitated ACP. METHODS: Twenty-six lay navigators from 11 PCC cancer centers in 4 states (Alabama, George, Tennessee, and Florida) completed in-depth, one-on-one semistructured interviews between June 2015 and August 2015. Data were analyzed using a thematic analysis approach. RESULTS: This evaluation identifies 3 levels-patient, lay navigator, and organizational factors in addition to training needs that influence ACP implementation. Key facilitators included physician buy-in, patient readiness, and navigators' prior experience with end-of-life decision-making. Lay navigators' perceived challenges to initiating ACP conversations included timing of the conversation and social and personal taboos about discussing dying. CONCLUSION: Our results suggest that further training and health system support are needed for lay navigators playing a vital role in improving the implementation of ACP among older patients with cancer. The lived expertise of lay navigators along with flexible longitudinal relationships with patients and caregivers may uniquely position this workforce to promote ACP.

RESUMO

PURPOSE: Little is known about the impact of family caregiving for adults with poor prognosis cancer on caregivers' own individual self-care practices. We explored differences in caregivers' discrete self-care practices associated with varying levels of caregiver well-being, preparedness, and decision-making self-efficacy. METHODS: Cross-sectional survey within eight community-based southeastern U.S. cancer centers was conducted. Family caregivers of Medicare beneficiaries ≥65 years with pancreatic, lung, brain, ovarian, head and neck, hematologic, or stage IV cancer completed measures of individual self-care practices (health responsibility, physical activity, nutrition, spiritual growth, interpersonal relations, stress management, and sleep), well-being (anxiety, depression, and health-related quality of life [HRQoL]), preparedness, and decision-making self-efficacy. RESULTS: Caregivers (n = 294) averaged 66 years, were mostly female (72.8%), white (91.2%), Protestant (76.2%), retired (54.4%), and patients' spouse/partner (60.2%). Approximately, half were rural-dwellers (46.9%) with incomes <$50,000 (53.8%). Most provided support 6-7 days/week (71%) for >1 year (68%). Nearly a quarter (23%) reported high depression and 34% reported borderline or high anxiety. Low engagement in all self-care practices was associated with worse caregiver anxiety, depression, and mental HRQoL (all p values < .05). Caregivers with lower health responsibility, spiritual growth, interpersonal relation, and stress management scores had lower preparedness and decision-making self-efficacy. CONCLUSIONS: A significant proportion of caregivers simultaneously report low engagement in all forms of self-care practices, high depression and anxiety, and low HRQoL mental health scores. Caregiver well-being, preparedness, and decision-making self-efficacy might be optimized through interventions targeted at enhancing health responsibility, stress management, interpersonal relationships, and spiritual growth self-care practices.

RESUMO

OBJECTIVE: This study examined differences in socio-demographic characteristics and health behaviors relevant to chronic medical conditions (CMCs) in the Mid-South region (Alabama, Mississippi, Louisiana, Kentucky, Tennessee, and Arkansas), and identified subpopulations with increased burden of chronic disease. METHODS: Data were obtained from the 2013 Behavioral Risk Factor Surveillance System. The top five most prevalent CMCs in the Mid-South were analyzed: asthma, high blood pressure (HBP), obesity, arthritis, and depression. Adjusted odds ratios (AOR) and confidence intervals (CI) of race-gender combinations were estimated using logistic regression. Differences in associations between socio-demographic characteristics and CMCs according to income were also examined. RESULTS: The weighted prevalence estimates of the top five CMCs ranged from 66% (asthma) to 20% (depression). Higher income and employment were associated with better outcomes in all five CMCs. Higher educational attainment and physical activity were associated with better HBP, obesity, and arthritis status. Black and white females had higher odds of asthma compared to white males (black AOR = 1.7, CI: 1.1-2.6, white AOR = 1.7, CI: 1.3-2.2). Black males had lower odds of arthritis (AOR = 0.8, CI: 0.6-0.9), while white females had higher odds (AOR = 1.3, CI: 1.2-1.4). Similarly, the odds of depression were lower among black males (AOR = 0.5, CI: 0.4-0.6) and higher among white females (AOR = 2.2, CI: 2.0-2.5). Income-related differences by race were observed for HBP and obesity. CONCLUSION: Disparities in CMCs are associated with income and disproportionately affect the black population. In the Mid-South, race and gender disparities in the top five chronic conditions are more prominent among higher-income rather than lower-income individuals.

RESUMO

INTRODUCTION: Cancer disparities continue to exist in the United States. Community health advisors (CHAs) can play a critical role in addressing cancer disparities. The American Cancer Society (ACS) implemented a 3-year pilot CHA program in the South based on an evidence-based program to increase breast cancer screening. STUDY DESIGN: Evaluation assessed the extent to which ACS successfully implemented the program. Quantitative data were tracked and reported by ACS staff, and qualitative data were collected through focus groups and interviews with volunteer participants. SETTING/PARTICIPANTS: The pilot was implemented in 28 communities in nine states. ACS staff recruited volunteer community network partners (CNPs) as local advisory groups, and volunteer CHAs to conduct outreach, education, and screening navigation. MEASURES: Outcome measures included number of individuals educated and screened, and number of communities reaching education and screening targets. Process measures included number of volunteers recruited, number of communities reaching recruitment targets, and implementation process, challenges, and successes. RESULTS: A total of 383 CHAs were recruited and recruitment goals were met in 68%; 31,439 individuals were educated, and 93% of communities reached education goals. In all, 5,056 individuals were screened, but screening goals were attained in only 36% of communities. CONCLUSION: This pilot demonstrates the ability of ACS to adapt and disseminate an evidence-based program to fit into its volunteer-based outreach model. ACS built community network partnerships, recruited a cadre of volunteers, and trained them to conduct education and screening navigation.

RESUMO

BACKGROUND: Although urine-based testing for human papillomavirus (HPV) is being explored as a practical approach for cervical cancer screening, whether the results differ by age, race, or indicators of excess body weight or in populations exposed to HPV vaccines has not been documented by previous studies. The purpose of this study was to determine the accuracy of urinary HPV testing for the presence of cervical HPVs and high-grade cervical intraepithelial lesions (grade 2 and 3 cervical intraepithelial neoplasia [CIN]) by the aforementioned population characteristics. METHODS: The study population consisted of 502 women diagnosed with different grades of CIN. HPV testing was performed with paired urine and cervical cell DNA with the Roche Diagnostics Linear Array test. Agreement coefficient 1 and probabilities were calculated to determine the accuracy of urinary HPV testing for the presence of cervical HPVs and CIN lesions. RESULTS: Substantial to almost perfect agreement (0.66-0.83) was observed in the detection of any HPV genotype in urine specimens versus cervical specimens, regardless of the population characteristics. Although the positive predictive value for the detection of CIN lesions was relatively low, the negative predictive value for CIN-3 was high (≥90%) among women positive for any of the urinary or cervical high-risk human papillomavirus (HR-HPV) genotypes or HPV genotypes not included in currently available HPV vaccines. CONCLUSIONS: The results demonstrate that urinary HPV testing provides highly satisfactory results for excluding the possibility of any cervical HPV infections, including HPV types not included in vaccines and CIN lesions associated with any HR-HPV, regardless of a woman's age, race, or excess body weight.

RESUMO

BACKGROUND: Treatment summaries and follow-up care plan information should be provided to cancer survivors. This study examines the association of receiving summaries and care plans with cancer survivor self-efficacy for chronic illness management, and whether self-efficacy was associated with health care utilization. METHODS: Four hundred forty-one cancer survivors (≥2 years from diagnosis and had completed treatment) ≥65 years old from 12 cancer centers across 5 states completed telephone surveys. Survivors responded to three questions about receiving a written treatment summary, written follow-up plan, and an explanation of follow-up care plans. Respondents completed the Stanford Chronic Illness Management Self-Efficacy Scale and reported emergency room visits and hospitalizations in the past year. Three multiple linear regression models estimated the association of written treatment summary, written follow-up care plan, and verbal explanation of follow-up plan with total self-efficacy score. Log-binomial models estimated the association of self-efficacy scores with emergency room visits and hospitalizations (yes/no). RESULTS: Among survivors, 40% and 35% received a written treatment summary and follow-up care plan, respectively. Seventy-nine percent received an explanation of follow-up care plans. Receiving a verbal explanation of follow-up care instructions was significantly associated with higher self-efficacy scores (ß = 0.72, p = .009). Higher self-efficacy scores were significantly associated with lower prevalence ratios of emergency room visits (prevalence ratio, 0.92; 95% confidence interval, 0.88-0.97) and hospitalizations (prevalence ratio, 0.94; 95% confidence interval, 0.89-0.99). CONCLUSION: Explanation of the follow-up care plan, beyond the written component, enhances survivor self-efficacy for managing cancer as a chronic condition-an important mediator for improving health care utilization outcomes. IMPLICATIONS FOR PRACTICE: Older cancer survivors (>65 years) are especially vulnerable to poor outcomes in survivorship because of the complexity of follow-up care and other chronic conditions. Delivering written treatment summaries, written follow-up care plans, and verbal explanations of follow-up care plans all independently increased the self-efficacy for chronic illness management among older survivors. In particular, delivering this information in the verbal format was significantly associated with higher self-efficacy and, subsequently, a lower likelihood of emergency room visits. Understanding the mechanism through which summaries and follow-up care plans may positively influence survivor health is critical to increasing the delivery of the information.

RESUMO

BACKGROUND: There is growing interest in psychosocial care and evaluating distress in patients with cancer. As of 2015, the Commission on Cancer requires cancer centers to screen patients for distress, but the optimal approach to implementation remains unclear. METHODS: We assessed the feasibility and impact of using distress assessments to frame lay navigator interactions with geriatric patients with cancer who were enrolled in navigation between January 1, 2014, and December 31, 2014. RESULTS: Of the 5,121 patients enrolled in our lay patient navigation program, 4,520 (88%) completed at least one assessment using a standardized distress tool (DT). Navigators used the tool to structure both formal and informal distress assessments. Of all patients, 24% reported distress scores of 4 or greater and 5.5% reported distress scores of 8 or greater. The most common sources of distress at initial assessment were pain, balance/mobility difficulties, and fatigue. Minority patients reported similar sources of distress as the overall program population, with increased relative distress related to logistical issues, such as transportation and financial/insurance questions. Patients were more likely to ask for help with questions about insurance/financial needs (79%), transportation (76%), and knowledge deficits about diet/nutrition (76%) and diagnosis (66%) when these items contributed to distress. CONCLUSIONS: Lay navigators were able to routinely screen for patient distress at a high degree of penetration using a structured distress assessment.

RESUMO

The Deep South Network for Cancer Control (DSNCC), initiated in 2000, is a dual-state, community-based participatory research infrastructure composed of academic and community partners committed to reducing cancer disparities among underserved African Americans in 12 designated counties of the Alabama Black Belt and the Mississippi Delta, 2 historically underserved areas of the country. Local residents trained as Community Health Advisors as Research Partners implemented a 3-tier community action plan (CAP) focused on promoting cancer screening, physical activity, and nutrition. Breast, cervical and colorectal cancer screening, healthy eating habits, and physical activity levels increased among many, but not all, African American women in the 12-county DSNCC coverage area. Seeking to improve our reach to include participants who reported they had never heard of the DSNCC or participated in the CAP, we conducted in-depth conversations with community residents about reasons for selective nonparticipation and ways to improve participation in the DSNCC community health interventions. Three patterns and their associated themes described ways to improve the penetration of CAP strategies and tailor them to effectively reach underserved African Americans in the intervention counties. We conclude with lessons learned for future interventions.

RESUMO

BACKGROUND: The Community Health Advisor (CHA) model has been widely used to recruit rural and low-income, mostly African American women into clinical and behavioral research studies. However, little is known about its effectiveness in promoting retention and adherence of such women in clinical trials. METHODS: The Community-Based Retention Intervention Study evaluated the effectiveness of a community-based intervention strategy using the CHA model and the empowerment theory to improve the retention and adherence of minority and low-income women in clinical trials. The research strategy included the training and use of the volunteer CHAs as research partners. The target population included women participating in the University of Alabama at Birmingham clinical site of the Atypical Squamous Cells of Undetermined Significance-Low-Grade Squamous Intraepithelial Lesion (ASCUS-LSIL) Triage Study (ALTS), a multicenter, randomized clinical trial. Two communities in Jefferson County, Alabama, that were matched according to population demographics were identified and randomly assigned to either an intervention group or a control group. Thirty community volunteers were recruited to be CHAs and to implement the intervention with the ALTS trial participants. In total, 632 ALTS participants agreed to participate in the project, including 359 in the intervention group, which received CHA care, and 273 in the control group, which received standard care. RESULTS: Adherence rates for scheduled clinic visits were significantly higher in the intervention group (80%) compared with the control group (65%; P < .0001). CONCLUSIONS: The results indicate that volunteer CHAs can be trained to serve as research partners and can be effective in improving the retention and adherence of minority and low-income women in clinical trials.

RESUMO

OBJECTIVE: We evaluated time to clearance of high risk (HR) HPV infection in relation to functional variants in three genes (CYP1A1, GSTT1, and GSTM1). METHODS: The study group consisted of 450 HR-HPV infected women from the Atypical squamous cells of undetermined significance-low-grade squamous intraepithelial Lesion Triage Study (ALTS) cohort followed up at the clinical center at Birmingham, Alabama. The Cox proportional hazard model with the Wei-Lin-Weisfeld (WLW) approach was used, controlling for relevant covariates. RESULTS: Women who were polymorphic for CYP1A1 experienced an HR-HPV clearance rate that was 20% (HR=0.80, p=0.04) lower than women without the polymorphism for CYP1A1, adjusting for all other cofactors. The GSTM1 null genotype was associated with higher HR-HPV clearance rate (HR=1.39, p=0.006). The polymorphism in GSTT1 was not significantly associated with time to clearance of HR-HPV. CONCLUSIONS: Xenobiotic metabolism genes may influence the natural history of HR-HPV infection and its progression to cervical cancer.

RESUMO

These NCCN Guidelines Insights focus on recent recommendations for cervical cancer screening and management of abnormal screening tests. When the NCCN Panel convened to update the NCCN Guidelines for Cervical Cancer Screening, they decided to adopt and endorse guidelines from other organizations to avoid duplication of effort. Therefore, in July 2013, after review and validation of consensus guidelines from the American Cancer Society, American Society for Colposcopy and Cervical Pathology, and American Society for Clinical Pathology, the NCCN Guidelines for Cervical Cancer Screening were discontinued.

RESUMO

BACKGROUND: There are no data available on human papillomavirus (HPV) infections in women living in the Mississippi Delta, where cervical cancer incidence and mortality among African American women is among the highest in the United States. The aim of this analysis was to report the age-specific prevalence of HPV in this population. METHODS: We recruited 443 women, 26-65 years of age, from the general population of women living in the Mississippi Delta to participate; 252 women had been screened for cervical cancer within the last 3 years while 191 had not. Women underwent a pelvic exam and had clinician-collected Pap sample taken for the routine cervical cancer screening by cytology. Women were asked to collect a self-collected specimen at home and return it to the clinic. Both specimens were tested for HPV genotypes. RESULTS: Four hundred and six women (91.6%) had HPV genotyping results for the clinician-collected and self-collected specimens. The prevalence of carcinogenic HPV was 18.0% (95% CI: 14.4%-22.1%) for clinician-collected specimens and 26.8% (95% CI: 22.6%-31.4%) for self-collected specimens. The concordance for the detection of carcinogenic HPV between clinician-collected and self-collected specimens was only fair (kappa = 0.54). While the prevalence of carcinogenic HPV in either sample decreased sharply with increasing age (ptrend< 0.01), the prevalence of non-carcinogenic HPV did not, especially the prevalence of HPV genotypes in the alpha 3/4/15 phylogenetic group. CONCLUSIONS: The prevalence of carcinogenic HPV in our sample of women living in the Mississippi Delta was greater than the prevalence reported in several other U.S. studies. The high carriage of HPV infection, along with lack of participation in cervical cancer screening by some women, may contribute to the high cervical cancer burden in the region.

RESUMO

BRCA1 gene mutations are responsible for hereditary breast and ovarian cancers. In sporadic breast tumors, BRCA1 dysfunction or aberrant subcellular localization is thought to be common. BRCA1 is a nuclear-cytoplasm shuttling protein and the reason for cytoplasmic localization of BRCA1 in young breast cancer patients is not yet known. We have previously reported BRCA1 proteins unlike K109R and cancer-predisposing mutant C61G to bind Ubc9 and modulate ER-α turnover. In the present study, we have examined the consequences of altered Ubc9 binding and knockdown on the subcellular localization and growth inhibitory function of BRCA1 proteins. Our results using live imaging of YFP, GFP, RFP-tagged BRCA1, BRCA1a and BRCA1b proteins show enhanced cytoplasmic localization of K109 R and C61G mutant BRCA1 proteins in normal and cancer cells. Furthermore, down-regulation of Ubc9 in MCF-7 cells using Ubc9 siRNA resulted in enhanced cytoplasmic localization of BRCA1 protein and exclusive cytoplasmic retention of BRCA1a and BRCA1b proteins. These mutant BRCA1 proteins were transforming and impaired in their capacity to inhibit growth of MCF-7 and CAL51 breast cancer cells. Interestingly, cytoplasmic BRCA1a mutants showed more clonogenicity in soft agar and higher levels of expression of Ubc9 than parental MCF7 cells. This is the first report demonstrating the physiological link between cytoplasmic mislocalization of mutant BRCA1 proteins, loss of ER-α repression, loss of ubiquitin ligase activity and loss of growth suppression of BRCA1 proteins. Thus, binding of BRCA1 proteins to nuclear chaperone Ubc9 provides a novel mechanism for nuclear import and control of tumor growth.

RESUMO

To explore alternative cervical cancer screening approaches in an underserved population, we compared the performance of human papillomavirus (HPV) DNA assays in combination with different sample collection methods for primary cervical screening in the Mississippi Delta region. Three specimens were collected from women aged 26 to 65 years who were either routinely undergoing screening (n = 252) or not (n = 191): clinician-collected cervical specimens, clinician-collected cervicovaginal specimens, and self-collected cervicovaginal specimens taken at home. A novel collection device and medium were used for cervicovaginal sampling. Specimens were tested by three HPV DNA assays: hybrid capture 2 (HC2; Qiagen Corp., Gaithersburg, MD), Linear Array (LA; Roche Molecular Systems, Pleasanton, CA), and Amplicor (Roche Molecular Systems, Pleasanton, CA). Liquid-based cytology was performed on cervical specimens. We compared the overall positivity (a proxy for clinical specificity) for any carcinogenic HPV genotype and calculated the agreement across assay and specimen type using McNemar's test for differences in test positivity. Across all three assays there were no significant differences between clinician-collected and self-collected cervicovaginal specimens (P > 0.01 for all comparisons). For both cervicovaginal specimens (clinician collected and self-collected), fewer women tested positive by HC2 than by LA or Amplicor (P < 0.01 for all comparisons). HC2 had the best agreement between specimens for all assays. HC2 is likely more clinically specific, although possibly less sensitive, than either PCR test. Thus, use of HC2 on cervicovaginal specimens for screening could result in fewer referrals compared to LA and Amplicor.

RESUMO

OBJECTIVE: The aim of the study was to increase participation in cervical cancer screening of under-screened women living in the Mississippi Delta, a U.S. population at high risk for cervical cancer. METHODS: We conducted a door-to-door feasibility study of women living in the Mississippi Delta to increase participation in cervical cancer screening in 2009-10. Women (n=119) aged 26-65 years who had not been screened in last 3 years or more, were not pregnant, and had a cervix were offered a cost-free choice: clinic-based Pap testing or home self-collection with HPV DNA testing. RESULTS: Seventy-seven women (64.7%) chose self-collection with HPV testing, of which sixty-two (80.5%) returned their self-collected specimen. By comparison, 42 women (35.3%) chose Pap testing, of which 17 (40.5%) attended their clinic appointment. Thus there was an almost 4-fold greater participation of under-screened women in self-collection with HPV testing than in free Pap testing (78.4% vs. 21.5%). CONCLUSIONS: We found that offering self-collection will increase participation in cervical cancer screening among under-screened populations living in the Mississippi Delta. Based on these preliminary results, we suggest that self-collection with HPV DNA testing might complement current Pap testing programs to reach under-screened populations of women, such as those living in the Mississippi Delta.
