Validity of state cancer registry treatment information for adolescent and young adult women.

ABSTRACT:

Background

Population-based cancer registries collect information on first course of treatment that may be utilized in research on cancer care quality, yet few studies have investigated the validity of this information. We examined the accuracy and completeness of registry-based treatment information in a cohort of adolescent and young adult women.

Methods

Women diagnosed with breast cancer, lymphoma, thyroid cancer, cervical/uterine cancer or ovarian cancer at ages 15-39 during 2003-2014 were identified using data from the North Carolina Central Cancer Registry (CCR) (N?=?2342). CCR data were linked to Medicaid and private insurance claims data, and claims were reviewed for the 12 months following diagnosis to identify cancer treatments received. Using claims data as the gold standard, we calculated the sensitivity and positive predictive value (PPV) of CCR data for receipt of chemotherapy, radiation and hormone therapy. We also compared dates of treatment initiation between the two data sources.

Results

For all cancer types combined, the sensitivity of the CCR data was high for chemotherapy (86%) and moderate for radiation (74%). PPVs were 82% and 83% for chemotherapy and radiation, respectively. Both the sensitivity (67%) and PPV (70%) were lower for hormone therapy for breast cancer. For all three treatment types, dates of initiation in the registry and the claims differed by ?30 days for most women.

Conclusions

In this cohort of young women, population-based cancer registry data on chemotherapy receipt was reasonably accurate and complete in comparison with insurance claims. Radiation and hormone therapy appeared to be less complete.

Project description:(1) Background: Adolescents and young adults (AYAs) who have been diagnosed with and treated for cancer have unique healthcare needs, but more research is needed to inform developmentally targeted cancer care for this population. The purpose of the current analyses was to describe the physical and psychosocial concerns and experiences of AYA cancer survivors during the post-treatment phase. (2) Methods: A national survey was conducted by the Canadian Partnership Against Cancer to evaluate the experiences and unmet needs of cancer survivors (?18 years) within the first 5 years following cancer treatment. The current analyses were conducted on the AYA survivor population (18-34 years). (3) Results: A total of 575 surveys were completed by AYAs. Of these, 61% were female, 51% were married/partnered, and 52% were 1-3 years post treatment. Approximately three-quarters report their physical or emotional health as good/very good. Overall, 88% reported at least one physical concern [mean of 3.98+2.11 physical concerns (range 0-9)], 90% reported at least one emotional concern [mean of 3.77+1.75 emotional concern (range 0-6)], and 79% reported at least one practical challenge [mean of 2.39+1.28 practical concerns (range 0-5)]. The most common concerns were anxiety/worry about cancer returning (83%), fatigue/tiredness (78%), and depression/loss of interest in daily activities (66%). On average, 43% of those reporting a concern sought help. Common reasons for not seeking help included not wanting to ask, being told that it was normal to feel the way they did, or embarrassment. Of those who did seek help, 37% encountered difficulty obtaining assistance. (4) Conclusions: These results suggest that post-treatment AYA cancer survivors have a high rate and number of physical, psychosocial, and practical concerns and are often not seeking or receiving help to address these. Proactive approaches to characterizing and eliminating barriers to obtaining appropriate care are needed.

Project description:ImportanceCancer diagnosis and treatment may adversely affect reproductive outcomes among female cancer survivors.ObjectiveTo compare the birth outcomes of adolescent and young adult cancer survivors (AYA [diagnosed at ages 15-39 years]) with those of women without a cancer diagnosis.Design, setting, and participantsThe North Carolina Central Cancer Registry (CCR) was used to identify female AYA cancer survivors diagnosed from January 2000 to December 2013; CCR records were linked to statewide birth certificate files from January 2000 to December 2014 to identify postdiagnosis live births to AYA survivors (n?=?2598). A comparison cohort of births to women without a recorded cancer diagnosis was randomly selected from birth certificate files (n?=?12?990) with frequency matching on maternal age and year of delivery.Main outcomes and measuresPrevalence of preterm birth, low birth weight, small-for-gestational-age births, cesarean delivery, and low Apgar score.ResultsOverall, 2598 births to AYA cancer survivors (mean [SD] maternal age, 31 [5] years) were included. Births to AYA cancer survivors had a significantly increased prevalence of preterm birth (prevalence ratio [PR], 1.52; 95% CI, 1.34-1.71), low birth weight (PR, 1.59; 95% CI, 1.38-1.83), and cesarean delivery (PR, 1.08; 95% CI, 1.01-1.14) relative to the comparison cohort of 1299. The higher prevalence of these outcomes was most concentrated among births to women diagnosed during pregnancy. Other factors associated with preterm birth and low birth weight included treatment with chemotherapy and a diagnosis of breast cancer, non-Hodgkin lymphoma, or gynecologic cancers. The prevalence of small-for-gestational-age births and low Apgar score (<7) did not differ significantly between groups.Conclusions and relevanceLive births to AYA cancer survivors may have an increased risk of preterm birth and low birth weight, suggesting that additional surveillance of pregnancies in this population is warranted. Our findings may inform the reproductive counseling of female AYA cancer survivors.

Project description:OBJECTIVE:To evaluate satisfaction with intrauterine device (IUD) insertion procedures among adolescent and young adult women. METHODS:This secondary analysis of data from a multisite, single-blind, sham-controlled randomized trial of women having a levonorgestrel 13.5-mg IUD inserted enrolled participants from March 2015 through July 2016 at three family planning clinics in Philadelphia, Pennsylvania. Eligible participants were 14-22 years of age, nulliparous, not pregnant, and English-speaking. Randomization was computer-generated allocation in block sizes of four to a 1% lidocaine paracervical or sham block. Only patients were blinded. Satisfaction was measured with three items that assessed overall satisfaction with the procedure, whether participants would recommend the IUD to a friend, and the perception that the IUD was worth the discomfort. Predictors included demographics, sexual and reproductive history, pain after IUD insertion, and treatment group. RESULTS:Ninety-five women enrolled; 93 (97.9%) were included in the analysis. Forty-five (47.4%) were white, 34 (36.0%) were black, 62 (66.0%) were privately insured, and 75 (79.0%) had used contraception previously. Most (n=73 [76.8%]) reported high overall satisfaction with the procedure, 64 (67.4%) would recommend an IUD to a friend, and 79 (83.2%) perceived the IUD was worth the discomfort. The odds of reporting high overall satisfaction were lower among adolescents compared with young adults (odds ratio [OR] 0.07, 95% CI 0.008-0.68); those who never had a gynecologic examination compared with those who had (OR 0.26, 95% CI 0.07-0.99); and decreased as pain score increased (OR 0.96, 95% CI 0.94-0.99). Higher pain scores were negatively correlated with the odds of recommending an IUD to a friend and perceiving the IUD was worth the discomfort. CONCLUSION:Adolescent and young adult women report high levels of satisfaction after the IUD insertion procedure. Young age, lack of experience with gynecologic examinations, and high pain were inversely related to satisfaction. CLINICAL TRIAL REGISTRATION:ClinicalTrials.gov, NCT02352714.
