Financial toxicity among people with metastatic cancer: findings from the Cancer Experience Registry.

PURPOSE: This study describes financial toxicity (FT) reported by people with metastatic cancer, characteristics associated with FT, and associations between FT and compensatory strategies to offset costs. METHODS: Cancer Support Community's Cancer Experience Registry data was used to identify respondents with a solid tumor metastatic cancer who completed the Functional Assessment of Chronic Illness Therapy COmprehensive Score for Financial Toxicity (FACIT-COST) measure. Multivariable logistic regression analyses examined associations between respondent characteristics and FT, and FT and postponing medical visits, nonadherence to medications, and postponing supportive and/or psychosocial care. RESULTS: 484 individuals were included in the analysis; the most common cancers included metastatic breast (31%), lung (13%), gynecologic (10%), and colorectal (9%). Approximately half of participants (50.2%) reported some degree of FT. Those who were non-Hispanic White, Hispanic, or multiple races (compared to non-Hispanic Black), and who reported lower income, less education, and being less than one year since their cancer diagnosis had greater odds of reporting FT. Individuals with any level of FT were also more likely to report postponing medical visits (Adjusted Odds Ratio [OR] 2.58; 95% Confidence Interval [CI] 1.45-4.58), suboptimal medication adherence (Adjusted OR 5.05; 95% CI 2.77-9.20) and postponing supportive care and/or psychosocial support services (Adjusted OR 4.16; 95% CI 2.53-6.85) compared to those without FT. CONCLUSIONS: With increases in the number of people living longer with metastatic cancer and the rising costs of therapy, there will continue to be a need to systematically screen and intervene to prevent and mitigate FT for these survivors.

Awareness and use of genetic testing: An analysis of the Health Information National Trends Survey 2020.

PURPOSE: Genetic testing is a tool used in a variety of settings for medical and nonhealth related purposes. The goal of this analysis was to better understand the awareness and use of genetic testing in the United States. METHODS: Data from the 2020 Health Information National Trends Survey 5 cycle 4 were used to assess the awareness and use of genetic testing by demographic characteristics, personal cancer history, and family cancer history. RESULTS: Overall, 75% of participants were aware of genetic testing and 19% of participants had genetic testing. Ancestry testing was the most common type of testing that the participants were aware of and had received. Non-Hispanic Asian, Non-Hispanic Black, and Hispanic respondents and participants with incomes less than $20,000 were less likely to be aware of and have received any type of genetic testing than the Non-Hispanic White participants and participants with higher income, respectively. Participants with a family history of cancer were more likely to be aware of cancer genetic testing than those without, and participants with a personal history of cancer were more likely to have had cancer genetic testing. CONCLUSION: It appears awareness of genetic testing is increasing in the United States, and differences in awareness persist by race/ethnicity and income.

The feasibility of web surveys for obtaining patient-reported outcomes from cancer survivors: a randomized experiment comparing survey modes and brochure enclosures.

BACKGROUND: Central cancer registries are often used to survey population-based samples of cancer survivors. These surveys are typically administered via paper or telephone. In most populations, web surveys obtain much lower response rates than paper surveys. This study assessed the feasibility of web surveys for collecting patient-reported outcomes via a central cancer registry. METHODS: Potential participants were sampled from Utah Cancer Registry records. Sample members were randomly assigned to receive a web or paper survey, and then randomized to either receive or not receive an informative brochure describing the cancer registry. We calculated adjusted risk ratios with 95% confidence intervals to compare response likelihood and the demographic profile of respondents across study arms. RESULTS: The web survey response rate (43.2%) was lower than the paper survey (50.4%), but this difference was not statistically significant (adjusted risk ratio = 0.88, 95% confidence interval = 0.72, 1.07). The brochure also did not significantly influence the proportion responding (adjusted risk ratio = 1.03, 95% confidence interval = 0.85, 1.25). There were few differences in the demographic profiles of respondents across the survey modes. Older age increased likelihood of response to a paper questionnaire but not a web questionnaire. CONCLUSIONS: Web surveys of cancer survivors are feasible without significantly influencing response rates, but providing a paper response option may be advisable particularly when surveying older individuals. Further examination of the varying effects of brochure enclosures across different survey modes is warranted.

Changing Hearts and Minds: Improving Outcomes in Cancer Treatment-Related Cardiotoxicity.

PURPOSE OF REVIEW: Cardiovascular effects from cancer treatment remains a leading cause of treatment-associated morbidity and mortality among cancer survivors. The National Cancer Institute and National Heart, Lung, and Blood Institute convened a Workshop in June 2018 entitled "Changing Hearts and Minds: Improving Outcomes in Cancer Treatment-Related Cardiotoxicity" to highlight progress, ongoing work, and update scientific priorities since the 2013 Workshop. Here we will describe these advances and provide an overview of the research priorities identified. RECENT FINDINGS: Since 2013, the National Institutes of Health has increased its support of cancer treatment-related cardiotoxicity research through the funding of grants and coordination of internal and external working groups. Workshop participants identified knowledge gaps and recommended over 20 new promising opportunities in basic and clinical cardiotoxicity research. Significant progress on mechanisms, detection, management, and prevention of cardiotoxicity has been made over the past 5 years, yet some critical gaps remain.

A prospective study of aromatase inhibitor therapy initiation and self-reported side effects.

PURPOSE: The objective of this study was to examine the associations between aromatase inhibitors (AIs) and side effects less frequently reported in the literature, including difficulty concentrating, forgetfulness, hair loss, and numbness in the extremities. METHODS: Data were analyzed from a cohort of 146 breast cancer patients initiating AI therapy and followed for 1 year and a cohort of 144 postmenopausal women without a history of cancer followed for 6 months. At baseline (prior to AI therapy for breast cancer patients), and at 3 months, 6 months, and 1 year (for breast cancer patients only), a comprehensive questionnaire was administered that ascertained data on symptoms. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using logistic regression for new onset of symptoms among the breast cancer patients compared to the women without a history of cancer. RESULTS: Among the breast cancer patients, 34.2% were treated with chemotherapy prior to AI treatment. Over the first 6 months of AI treatment, breast cancer patients had significantly higher odds of reporting new onset of forgetfulness (OR 4.00; 95% CI 1.67, 9.59), difficulty concentrating (OR 2.73; 95% CI 1.29; 5.78), hair loss (OR 4.12; 95% CI 1.86, 9.17), and numbness/tingling in the extremities (OR 2.47; 95% CI 1.09, 5.62) compared to women without a history of cancer. Similar increases in odds were observed for the subgroup of women not treated with chemotherapy versus the comparison group. CONCLUSIONS: AI-related symptoms should be monitored and addressed so that adherence to therapy is maintained.

Cardiovascular Health among Black and White Breast Cancer Patients Initiating Aromatase Inhibitor Therapy.

The purpose of this study was to compare the cardiovascular health of Black and White breast cancer patients undergoing adjuvant treatment. Baseline data from a cohort study of Black (n = 45) and White (n = 101) breast cancer patients initiating aromatase inhibitor treatment were analyzed. Participants had a cardiovascular health assessment, including carotid intimal medial thickness measurement, donated a blood sample, and completed a questionnaire. Atherosclerotic cardiovascular disease (ASCVD) event risk scores were calculated. Compared to their White counterparts, the Black patients had a significantly higher median ASCVD risk score (p = 0.009) and had a higher number of CVD risk factors (p < 0.05). Black patients were also more likely to have hypertension, diabetes, or to be obese than the White participants. The prevalence of cardiovascular disease and cardiovascular disease risk factors among Black and White breast cancer patients is high, and racial disparities exist which may have treatment implications.

Sleep disordered breathing risk in childhood cancer survivors: an exploratory study.

BACKGROUND: Sleep disordered breathing (SDB) is emerging as a significant health condition for children. The purpose of this study is to evaluate SDB symptoms in childhood cancer survivors and identify associations with quality of life (QOL) and psychological symptoms. PROCEDURE: A sample of 62 survivors aged 8-18 years were recruited during routine survivorship visits. All subjects and their parents completed questionnaires to evaluate sleep, QOL and psychological symptoms; scales included were: Pediatric Sleep Questionnaire, Sleep Disordered Breathing Subscale (PSQ-SDBS), Pediatric Quality of Life Inventory (PedsQL) and Depression Anxiety Stress Scale (DASS-21). Continuous data were used for all scales and a threshold score of >0.33 on the PSA-SDBS was used to identify risk of SDB. The relationships between measures of sleep and independent variables were examined using Pearson correlations and multiple linear regression models for significant associations. RESULTS: Of the 62 subjects enrolled, underlying diagnoses included 29 leukemias, 30 solid tumors and 3 non-malignant diseases. Nineteen percent of subjects were identified as having SDB risk on the PSQ-SDBS. The lowest mean PedsQL subscale score for parent and child ratings were school QOL; Parent mean 73(±SD 19) and Child mean 71(±SD 20). The severity of SDB per the PSQ was significantly associated with reduced total and school QOL which remained significant after adjusting for stress. CONCLUSIONS: Symptoms suggestive of SDB are common in childhood cancer survivors with negative implications for overall quality of life and school performance.

Musculoskeletal pain and health-related quality of life among breast cancer patients treated with aromatase inhibitors.

OBJECTIVE: This study aims to examine the associations between musculoskeletal pain and health-related quality of life (HR-QOL) among breast cancer patients on aromatase inhibitors (AIs) and women without a history of breast cancer. METHODS: A cross-sectional study was conducted among 68 breast cancer patients on AIs for an average of 3.5 years and 137 postmenopausal women without a history of cancer. Musculoskeletal pain was assessed using a 10-cm visual analog scale; HR-QOL was examined using the Medical Outcomes Study Short Form (SF-36) health survey. Linear regression was used to estimate the associations between pain and HR-QOL in both groups. RESULTS: Approximately 64 % of the breast cancer patients and women in the comparison group reported musculoskeletal pain. Among women with breast cancer, those with pain had significantly lower HR-QOL scores in the physical (52.2 vs. 42.6; p < 0.001) and mental (52.7 vs. 45.5; p = 0.01) component summary scores compared with those without pain. In the comparison group, pain was associated with significantly lower scores in the physical (55.4 vs. 46.0; p < 0.001), but not the mental, component summary score (52.1 vs. 52.4; p = 0.82). The significant associations between pain and HR-QOL persisted after confounder adjustment in both groups. Among women with similar severity of pain, breast cancer patients reported significantly lower HR-QOL in the mental summary component compared with the women in the comparison group. CONCLUSIONS: Among breast cancer patients, musculoskeletal pain adversely affects both mental and physical components of HR-QOL. Preventing or treating AI-associated musculoskeletal pain may improve overall HR-QOL among breast cancer patients treated with AIs.

Association of obesity and sleep problems among breast cancer survivors: results from a registry-based survey study.

PURPOSE: Sleep-related complaints are common among breast cancer survivors. However, the risk factors underlying sleep disturbances in this population are not completely understood. Some studies have shown that maintaining normal weight can result in a reduced risk of cancer-related symptoms, including sleep problems; however, data from published studies are not consistent. This study examined the associations between body mass index (BMI) and sleep-related complaints in breast cancer survivors. METHODS: Self-reported survey data from 861 breast cancer survivors at a single institution were analyzed. BMI was calculated based on self-reported weight and height at the time of the survey. Daytime sleepiness was assessed using the Epworth Sleepiness Scale. Average sleep duration was calculated based on the reported hours of sleep on a typical weekday and weekend. Associations between BMI and the sleep outcomes were estimated using multivariable logistic regression. RESULTS: In adjusted models, BMI was not significantly associated with either excessive daytime sleepiness or "short" sleep pattern (≤ 6 h) in our sample of breast cancer survivors. Younger age, presence of strong acute pain, and lower level of education were independent risk factors for excessive daytime sleepiness. African American race, presence of strong acute pain, and lower level of education were independent risk factors for being a short sleeper. CONCLUSIONS: Findings from this study indicate that BMI is not independently associated with sleep-related outcomes among breast cancer survivors. More research is needed to identify cancer survivors who are at increased risk for sleep disturbances as well as the mechanisms that underlie such disturbances.

Change in Pain and Quality of Life Among Women Enrolled in a Trial Examining the Use of Narrow Band Imaging During Laparoscopic Surgery for Suspected Endometriosis.

STUDY OBJECTIVE: To examine whether the addition of narrow band imaging (NBI) to traditional white light imaging during laparoscopic surgery impacts pain and quality of life (QOL) at 3 and 6 months after surgery among women with suspected endometriosis and/or infertility. DESIGN: A randomized controlled trial (Canadian Task Force classification level I). SETTING: The trial was conducted in 2 medical centers. PATIENTS: From October 2011 to November 2013, 167 patients undergoing laparoscopic examination for suspected endometriosis and/or infertility were recruited. The analytic study sample includes 148 patients with pain and QOL outcome data. INTERVENTIONS: Patients were randomized in a 3:1 ratio to receive white light imaging followed by NBI (WL/NBI) or white light imaging only (WL/WL). MEASUREMENTS AND MAIN RESULTS: Questionnaires were administered at baseline and at 3- and 6-month follow-up time points. Average and most severe pain at each time point were assessed using a 10-cm visual analog scale. QOL was measured using the Endometriosis Health Profile-30. Baseline characteristics were similar for the study groups. The WL/NBI and WL/WL groups had similar reductions in pain at 3 and 6 months. In addition, QOL improved similarly for both the WL/NBI and WL/WL groups at 3 and 6 months. CONCLUSION: Laparoscopic surgery for suspected endometriosis is associated with a reduction in pain and an improvement in QOL. The differences in pain reduction and QOL improvement, which are noted at 3 months and remain stable at 6 months after surgery, are similar for those undergoing surgery with WL/NBI compared with those undergoing surgery under traditional white light conditions.

Sensitivity of Narrow Band Imaging Compared With White Light Imaging for the Detection of Endometriosis.

STUDY OBJECTIVE: To evaluate the ability of narrow band imaging (NBI) in conjunction with standard white light imaging to improve the detection and diagnosis of endometriosis during laparoscopic evaluation compared with white light imaging alone. Sensitivity of NBI in detecting endometriosis was assessed and compared with white light imaging. DESIGN: Randomized controlled trial. CLASSIFICATION OF STUDY DESIGN: LEVEL I: Evidence obtained from a properly designed, randomized, controlled trial. SETTING: The trial was conducted in 2 medical centers. PATIENTS: One hundred sixty-seven women undergoing laparoscopic evaluation for suspected endometriosis and/or infertility were recruited. Of these, 150 were assessable to determine sensitivity of NBI compared with white light imaging for the detection of endometriotic lesions. INTERVENTIONS: Patients were randomized in a 3:1 ratio to receive white light imaging followed by NBI or white light imaging only. The pelvis was systematically visualized with each assigned imaging modality; lesions were recorded under each visualization and then resected. All patients had white light imaging on the first visualization followed by either a second white light examination (control arm) or NBI examination (intervention arm). MEASUREMENTS: Pathology of resected lesions was the criterion standard for evaluating sensitivity and was conducted at each institution. The method of detection of the lesion (white light or NBI) was masked. Central pathology review was conducted for a randomly selected 10% sample of specimens and for those lesions visualized under only 1 imaging modality among patients assigned to the intervention arm. The sensitivity was assessed for each modality (white light and NBI) and compared using a McNemar's test. MAIN RESULTS: Among the group randomized to receive both white light and NBI, 4 patients had lesions detected with NBI but no lesions detected with white light. Among the 255 lesions confirmed as endometriosis by pathologic review, all were detected by NBI for a sensitivity of 100%; 79% were detected by white light imaging (p < .001). CONCLUSION: The addition of NBI to white light imaging increased the number of endometriotic lesions identified during laparoscopy and the diagnosis of endometriosis compared with the use of white light imaging alone.

Racial differences in depressive symptoms and self-rated health among breast cancer survivors on aromatase inhibitor therapy.

The goal of this survey-based study was to examine whether aromatase inhibitor (AI) therapy was associated with depressive symptoms and self-rated health among Black and White breast cancer survivors (N = 761). Results showed that among Black, but not White, breast cancer survivors current AI therapy was associated with a significant increase in the odds of both depressive symptoms (OR 3.59; 95% CI 1.01, 13.00) and poorer self-rated health (OR 3.16; 95% CI 1.06, 9.46). Presence of pain was significantly associated with increased odds of both outcomes among both groups. The findings underscore the importance of addressing not only physical but mental health among breast cancer survivors on AIs, especially those of Black race.

Marital status and optimism score among breast cancer survivors.

PURPOSE: There are an increasing number of breast cancer survivors, but their psychosocial and supportive care needs are not well-understood. Recent work has found marital status, social support, and optimism to be associated with quality of life, but little research has been conducted to understand how these factors relate to one another. METHODS: Survey data from 722 breast cancer survivors were analyzed to estimate the association between marital status and optimism score, as measured using the Life Orientation Test-Revised. Linear regression was used to estimate the relationship of marital status and optimism, controlling for potential confounding variables and assessing effect modification. RESULTS: The results showed that the association between marital status and optimism was modified by time since breast cancer diagnosis. Specifically, in those most recently diagnosed (within 5 years), married breast cancer survivors had a 1.50 higher mean optimism score than unmarried survivors (95 % confidence interval (CI) 0.37, 2.62; p = 0.009). The difference in optimism score by marital status was not present more than 5 years from breast cancer diagnosis. CONCLUSIONS: Findings suggest that among breast cancer survivors within 5 years since diagnosis, those who are married have higher optimism scores than their unmarried counterparts; this association was not observed among longer-term breast cancer survivors. Future research should examine whether the difference in optimism score among this subgroup of breast cancer survivors is clinically relevant.

Association between race and physical functioning limitations among breast cancer survivors.

PURPOSE: The goal of this study was to examine differences in physical functioning limitations among African-American and white breast cancer survivors. METHODS: Data were analyzed from 115 African-American and 712 white breast cancer survivors who responded to a hospital registry-based survey. Physical functioning limitations were assessed using a series of eight questions in which individuals were asked about their ability to perform a physical task such as walking a quarter of a mile. A four-category summary score, representing overall severity of limitation, was created using participant responses to the eight questions. Ordinal logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for the association between race and physical functioning limitation adjusted for potential confounders. RESULTS: In the unadjusted model, the African-American breast cancer survivors were more than twice as likely to have a greater degree of physical functioning limitation compared to their white counterparts (OR 2.31; 95% CI 1.59, 3.38). After adjustment for covariates, including body mass index (BMI), the race OR was attenuated and no longer statistically significant (OR 1.44; 95% CI 0.92, 2.27). CONCLUSIONS: Findings from this study showed that African-American breast cancer survivors were more likely to have worse physical functioning limitations than their white counterparts; however, much of this disparity was due to racial differences in other variables such as BMI. Future research should focus on effective interventions targeting modifiable risk factors of physical functioning limitations among breast cancer survivors with the goal of improving quality of life.

Primary care for cancer survivors: a review of national institutes of health-funded grants 2017-2022.

PURPOSE: To describe the characteristics of National Institutes of Health (NIH) grants on primary care cancer research in cancer survivorship funded over the past 5 years. METHODS: Research project grants (RPG) funded during Fiscal Year (FY) 2017 to 2022 focused on cancer survivorship were identified using a text mining algorithm of words from the NIH Research, Condition, and Disease Categorization (RCDC) thesaurus with survivorship-relevant terms. Grants were then reviewed and double-coded to identify those that were carried out in a primary care setting, targeted primary care providers, or had primary care providers in the study team. RESULTS: A total of 24 grants were identified; 23 were funded by the National Cancer Institute and one was funded by the National Institute on Minority Health and Health Disparities. The majority were funded under the R01 mechanism (70.8%) and led by established investigators. Most were interventional design (91.7%), including both survivors and providers (79.2%), and focused care coordination or healthcare utilization (91.7%). CONCLUSIONS: Grants focused on primary care cancer survivorship are uncommon in the NIH portfolio. IMPLICATIONS FOR SURVIVORS: For the over 18 million cancer survivors in the USA, being cared for in a primary care setting is common. Yet, NIH-funded research on primary care cancer survivorship is sparse.

Palliative Intent Treatment and Palliative Care Delivery for Individuals With Advanced Nonsmall Cell Lung Cancer and Melanoma: A Patterns of Care Study.

Introduction: This study aimed to describe the patterns of palliative intent treatment and/or palliative care (PC) delivery among a population-based sample of individuals diagnosed with advanced nonsmall cell lung cancer (NSCLC) or advanced melanoma. Methods: Data from 655 advanced-stage melanoma patients and 2688 advanced-stage NSCLC patients included in the National Cancer Institute's 2017/2018 Patterns of Care study were analyzed. Bivariate and multivariate logistic regression analyses examined factors associated with (1) receipt of PC (including palliative surgery, radiation, and/or systemic therapy after cancer diagnosis, and PC consultations); and (2) timing from diagnosis to receipt of PC. Proportional hazards models also examined factors associated with timing of receipt of PC after diagnosis. Results: A total of 23.5% of those with melanoma and 52.6% of those with NSCLC received some type of PC. For melanoma, stage 4 (vs. stage 3) was associated with higher receipt of PC and receipt within three months of diagnosis. For NSCLC, stage 4 (vs. stage 3) and a diagnosis of depression or psychosocial distress within three months of diagnosis were significantly associated with receipt of PC and receipt within three months of diagnosis. Conclusion: Study findings indicate that those with advanced-stage cancer or who report distress are more likely to receive palliative intent treatment and/or PC. Given that individuals with advanced cancers are living longer and often experience long-lasting symptoms, it is critical to identify and overcome barriers for broadly delivering comprehensive palliative and supportive care.

Advancing health equity in cancer survivorship research: National institutes of health 2017-2022 portfolio review.

BACKGROUND: Communities and researchers have called for a paradigm shift from describing health disparities to a health equity research agenda that addresses structural drivers. Therefore, we examined whether the cancer survivorship research portfolio has made this shift. METHODS: We identified grants focused on populations experiencing health disparities from the National Institutes of Health (NIH) Cancer Survivorship Research Portfolio (N = 724), Fiscal Years 2017-2022. Grant characteristics were abstracted, drivers of health disparities were mapped onto the levels and domains of influence, and opportunities for future research were identified. RESULTS: A total of 147 survivorship grants focused on health disparities were identified, of which 73.5% of grants focused on survivors from racial and ethnic minoritized groups, 25.9% living in rural areas, 24.5% socioeconomically disadvantaged, and 2.7% sexual and gender minority groups. Study designs were 51.0% observational. 82.3% of grants measured or intervened on at least one individual-level of influence, compared to higher levels of influence (32.7% interpersonal, 41.5% institutional/community, and 12.2% societal). Behavioral and healthcare system domains of influence were commonly represented, especially at the individual level (47.6% and 36.1%, respectively). Less frequently represented was the physical/built environment (12.2%). CONCLUSIONS: NIH-funded cancer survivorship research on health disparities is still focused on individual-level of influence. However, the proportion of grants examining structural and social drivers as well as the mechanisms that drive disparities in healthcare and health outcomes among cancer survivors have increased over time. Gaps in funded research on specific populations, cancer types, and focus areas of survivorship science were identified and warrant priority.

Survivorship concerns among individuals diagnosed with metastatic cancer: Findings from the Cancer Experience Registry.

INTRODUCTION: Individuals with metastatic cancer experience many medical, physical, and emotional challenges due to changing medical regimens, oscillating disease states, and side effects. The purpose of this study was to describe the type and prevalence of survivorship concerns reported by individuals with metastatic cancer, and their associations with cancer diagnosis, treatment, and socio-demographic variables. METHODS: This study utilized data from the Cancer Support Community's Cancer Experience Registry. Individuals were included if they self-reported a solid tumor metastatic cancer and completed CancerSupportSource, which evaluates five domains of concerns (emotional well-being, symptom burden, body image/healthy lifestyle, healthcare team communication, and relationships/intimacy). Multivariable linear regression examined associations between independent predictors of each survivorship concern domain. RESULTS: Of the 403 included participants, individuals reported a metastatic diagnosis of breast (43%), colorectal (20%), prostate (7%), lung (7%), gynecologic cancer (6%) and other. Nearly all (96%) reported at least one survivorship concern, with the most prevalent concern about cancer progression or recurrence. Survivorship concerns were higher across multiple domains for individuals unemployed due to disability. Individuals who were less than five years since diagnosis reported higher concerns related to emotional well-being, symptom burden, and healthcare communication compared to those more than five years since diagnosis. CONCLUSION: Individuals with metastatic cancer experience a variety of moderate-to-severe survivorship concerns that warrant additional investigation. IMPLICATIONS FOR CANCER SURVIVORS: As the population of individuals with metastatic cancer lives longer, future research must investigate solutions to address modifiable factors associated with survivorship concerns, such as unemployment due to disability.

Prevalence of cancer survivors in the United States.

BACKGROUND: With aging of the population and improvements in diagnosis, treatment, and supportive care, the number of cancer survivors in the United States (US) has increased; updated prevalence estimates are needed. METHODS: Cancer prevalence on January 1, 2022 was estimated using the Prevalence Incidence Approach Model, utilizing incidence, survival, and mortality. Prevalence by age decade, sex, and time from diagnosis were calculated. The percentage of cancer survivors in the projected US population by age and sex was calculated as the ratio of the sex-specific projected prevalence to the sex-specific projected US population. RESULTS: There were an estimated 18.1 million US cancer survivors as of January 1, 2022. From 2022 to 2030, the number of US cancer survivors is projected to increase to 21.6 million; by 2040, the number is projected to be 26 million. Long-term survivors are highly prevalent; in 2022, 70% of cancer survivors survived 5 years or more after diagnosis, and 11% of cancer survivors survived 25 years or more after diagnosis. Among all US females aged 40-54, 3.6% were cancer survivors; among females aged 65-74, 14.5% were cancer survivors; among females aged 85 and older, 36.4% were cancer survivors. Among all US males aged 40-54, 2.1% were cancer survivors; among males aged 65-74, 16% were cancer survivors; among those aged 85 and older, 48.3% were cancer survivors. CONCLUSIONS: Cancer survivors are growing in number. In the US, most cancer survivors are long-term and very long-term survivors, representing a significant proportion of the US population.

Aromatase inhibitor therapy and hair loss among breast cancer survivors.

The objective of this study was to examine the associations between aromatase inhibitor therapy and hair loss or hair thinning among female breast cancer survivors. Data were analyzed from 851 female breast cancer survivors who responded to a hospital registry-based survey. Data on hair loss, hair thinning, demographic characteristics, and health habits were based on self-report; data on aromatase inhibitor therapy were collected on the survey and verified using medical record review. Logistic regression was used to estimate the odds ratios (ORs) and 95 % confidence intervals (CIs) for the associations between aromatase inhibitor therapy and the hair outcome variables adjusted for potential confounders, including age and chemotherapy treatment. The results showed that 22.4 % of the breast cancer survivors reported hair loss and 31.8 % reported hair thinning. In the confounder-adjusted analyses, breast cancer survivors who were within 2 years of starting aromatase inhibitor treatment at the time of survey completion were approximately two and a half times more likely to report reporting hair loss (OR 2.55; 95 % CI 1.19-5.45) or hair thinning (OR 2.33; 95 % CI 1.10-4.93) within the past 4 weeks compared to those who were never treated with an aromatase inhibitor. Current aromatase inhibitor use for two or more years at the time of the survey and prior use were significantly associated with hair thinning (current users, ≥2 years: OR 1.86; prior users: OR 1.62), but not hair loss. Findings from this study suggest that aromatase inhibitor use is associated with an increased risk of hair loss and hair thinning independent of chemotherapy and age; these side effects are likely due to the substantial decrease in estrogen concentrations resulting from treatment with this drug. Future research should focus on examining these associations in a prospective manner using more detailed and objective measures of hair loss and thinning.
