RESUMEN

Lung cancer is the leading cause of mortality and person-years of life lost from cancer among US men and women. Early detection has been shown to be associated with reduced lung cancer mortality. Our objective was to update the American Cancer Society (ACS) 2013 lung cancer screening (LCS) guideline for adults at high risk for lung cancer. The guideline is intended to provide guidance for screening to health care providers and their patients who are at high risk for lung cancer due to a history of smoking. The ACS Guideline Development Group (GDG) utilized a systematic review of the LCS literature commissioned for the US Preventive Services Task Force 2021 LCS recommendation update; a second systematic review of lung cancer risk associated with years since quitting smoking (YSQ); literature published since 2021; two Cancer Intervention and Surveillance Modeling Network-validated lung cancer models to assess the benefits and harms of screening; an epidemiologic and modeling analysis examining the effect of YSQ and aging on lung cancer risk; and an updated analysis of benefit-to-radiation-risk ratios from LCS and follow-up examinations. The GDG also examined disease burden data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program. Formulation of recommendations was based on the quality of the evidence and judgment (incorporating values and preferences) about the balance of benefits and harms. The GDG judged that the overall evidence was moderate and sufficient to support a strong recommendation for screening individuals who meet the eligibility criteria. LCS in men and women aged 50-80 years is associated with a reduction in lung cancer deaths across a range of study designs, and inferential evidence supports LCS for men and women older than 80 years who are in good health. The ACS recommends annual LCS with low-dose computed tomography for asymptomatic individuals aged 50-80 years who currently smoke or formerly smoked and have a ≥20 pack-year smoking history (strong recommendation, moderate quality of evidence). Before the decision is made to initiate LCS, individuals should engage in a shared decision-making discussion with a qualified health professional. For individuals who formerly smoked, the number of YSQ is not an eligibility criterion to begin or to stop screening. Individuals who currently smoke should receive counseling to quit and be connected to cessation resources. Individuals with comorbid conditions that substantially limit life expectancy should not be screened. These recommendations should be considered by health care providers and adults at high risk for lung cancer in discussions about LCS. If fully implemented, these recommendations have a high likelihood of significantly reducing death and suffering from lung cancer in the United States.

RESUMEN

OBJECTIVE: In the U.S., uterine cancer incidence is rising, with racial and ethnic minorities experiencing the largest increases. We performed age-period-cohort analyses using novel methods to examine the contribution of age at diagnosis (age), year of diagnosis (period), and birth cohort (cohort), to trends in uterine cancer incidence. METHODS: We used uterine cancer incidence data from the Surveillance, Epidemiology, and End Result (SEER) 12 database (1992-2019), and performed hysterectomy-correction. We generated hexamaps to visualize age, period, and cohort effects, and used mutual information to estimate the percent contribution of age, period, and cohort effects, individually and combined, on uterine cancer incidence, overall and by race and ethnicity and histology. RESULTS: Hexamaps showed an increase in uterine cancer in later time periods, and a cohort effect around 1933 showing a lower incidence compared with earlier and later cohorts. Age, period, and cohort effects combined contributed 86.6% (95% CI: 86.4%, 86.9%) to the incidence. Age effects had the greatest contribution (65.1%, 95% CI: 64.3%, 65.9), followed by cohort (20.7%, 95% CI: 20.1%, 21.3%) and period (14.2%, 95% CI: 13.7%, 14.8%) effects. Hexamaps showed higher incidence in recent years for non-Hispanic Blacks and non-endometrioid tumors. CONCLUSIONS: Age effects had the largest contribution to uterine cancer incidence, followed by cohort and period effects overall and across racial and ethnic groups and histologies. IMPACT: These findings can inform uterine cancer modeling studies on the effects of interventions that target risk factors which may vary across age, period, or cohort.

RESUMEN

BACKGROUND: Contrary to clinical guidelines, there has been a decrease over time in estrogen therapy use in premenopausal women undergoing bilateral oophorectomy for benign indications. OBJECTIVE: This study aimed to estimate the excess morbidity and mortality associated with current patterns of estrogen therapy use in women who undergo bilateral oophorectomy with hysterectomy for benign indications. STUDY DESIGN: We developed 2 Bayesian sampling Markov state-transition models to estimate the excess disease incidence (incidence model) and mortality (mortality model). The starting cohort for both models were women who had undergone bilateral oophorectomy with hysterectomy for benign indications at the age of 45 to 49 years. The models tracked outcomes in 5-year intervals for 25 years. The incidence model estimated excess incidence of breast cancer, lung cancer, colorectal cancer, coronary heart disease, and stroke, whereas the mortality model estimated excess mortality due to breast cancer, lung cancer, coronary heart disease, and all-other-cause mortality. The models compared current rates of estrogen therapy use with optimal (100%) use and calculated the mean difference in each simulated outcome to determine excess disease incidence and death. RESULTS: By 25 years after bilateral oophorectomy with hysterectomy, there were an estimated 94 (95% confidence interval, -158 to -23) fewer colorectal cancer cases, 658 (95% confidence interval, 339-1025) more coronary heart disease cases, and 881 (95% confidence interval, 402-1483) more stroke cases. By 25 years after bilateral oophorectomy with hysterectomy, there were an estimated 189 (95% confidence interval, 59-387) more breast cancer deaths, 380 (95% confidence interval, 114-792) more coronary heart disease deaths, and 759 (95% confidence interval, 307-1527) more all-other-cause deaths. In sensitivity analyses where we defined estrogen therapy use as a duration of >2 years of use, these differences increased >2-fold. CONCLUSION: Underuse of estrogen therapy in premenopausal women who undergo oophorectomy is associated with substantial excess morbidity and mortality.

RESUMEN

BACKGROUND: Opioid misuse is a public health crisis, and unused postoperative opioids are an important source. Although 70% of pills prescribed go unused, only 9% are discarded. This study evaluated whether an inexpensive pill-dispensing device with mail return capacity could enhance disposal of unused opioids after cancer surgery. METHODS: A prospective pilot study was conducted among adult patients who underwent major cancer-related surgery. Patients received opioid prescriptions in a mechanical device (Addinex) linked to a smartphone application (app). The app provided passwords on a prescriber-defined schedule. Patients could enter a password into the device and receive a pill if the prescribed time had elapsed. Patients were instructed to return the device and any unused pills in a disposal mailer. The primary end point was feasibility of device return, defined as ≥50% of patients returning the device within 6 weeks of surgery. Also explored was total pill use and return as well as patient satisfaction. RESULTS: Among 30 patients enrolled, the majority (n = 24, 80%) returned the device, and 17 (57%) returned it within 6 weeks of surgery. In total, 567 opioid pills were prescribed and 170 (30%) were used. Of 397 excess pills, 332 (84% of unused pills, 59% of all pills prescribed) were disposed of by mail. Among 19 patients who obtained opioids from the device, most (n = 14, 74%) felt the benefits of the device justified the added steps involved. CONCLUSIONS: Use of an inexpensive pill-dispensing device with mail return capacity is a feasible strategy to enhance disposal of unused postoperative opioids.

RESUMEN

BACKGROUND: Cancer survivors treated with any dose of radiation to the abdomen, pelvis, spine, or total body irradiation (TBI) are at increased risk for developing colorectal cancer (CRC) compared to the general population. Since earlier detection of CRC is strongly associated with improved survival, the Children's Oncology Group (COG) Long-Term Follow-Up Guidelines recommend that these high-risk cancer survivors begin CRC screening via a colonoscopy or a multitarget stool DNA test at the age of 30 years or 5 years following the radiation treatment (whichever occurs last). However, only 37% (95% CI 34.1-39.9%) of high-risk survivors adhere to CRC surveillance. The Activating cancer Survivors and their Primary care providers (PCP) to Increase colorectal cancer Screening (ASPIRES) study is designed to assess the efficacy of an intervention to increase the rate of CRC screening among high-risk cancer survivors through interactive, educational text-messages and resources provided to participants, and CRC screening resources provided to their PCPs. METHODS: ASPIRES is a three-arm, hybrid type II effectiveness and implementation study designed to simultaneously evaluate the efficacy of an intervention and assess the implementation process among participants in the Childhood Cancer Survivor Study (CCSS), a North American longitudinal cohort of childhood cancer survivors. The Control (C) arm participants receive electronic resources, participants in Treatment arm 1 receive electronic resources as well as interactive text messages, and participants in Treatment arm 2 receive electronic educational resources, interactive text messages, and their PCP's receive faxed materials. We describe our plan to collect quantitative (questionnaires, medical records, study logs, CCSS data) and qualitative (semi-structured interviews) intervention outcome data as well as quantitative (questionnaires) and qualitative (interviews) data on the implementation process. DISCUSSION: There is a critical need to increase the rate of CRC screening among high-risk cancer survivors. This hybrid effectiveness-implementation study will evaluate the effectiveness and implementation of an mHealth intervention consisting of interactive text-messages, electronic tools, and primary care provider resources. Findings from this research will advance CRC prevention efforts by enhancing understanding of the effectiveness of an mHealth intervention and highlighting factors that determine the successful implementation of this intervention within the high-risk cancer survivor population. TRIAL REGISTRATION: This protocol was registered at clinicaltrials.gov (identifier NCT05084833 ) on October 20, 2021.

RESUMEN

PURPOSE: Prolonged use of controlled substances can place patients at increased risk of dependence and complications. Women who have mastectomy and reconstructive surgery (M + R) may be vulnerable to becoming new persistent users (NPUs) of opioid and sedative-hypnotic medications. METHODS: Using the MarketScan health-care claims database, we identified opioid- and sedative-hypnotic-naïve women who had M + R from 2008 to 2017. Women who filled ≥ 1 peri-operative prescription and ≥ 2 post-operative prescriptions within one year after surgery were classified as NPUs. Univariate and multivariable logistic regression analyses were used to estimate rates of new persistent use and predictive factors. Risk summary scores were created based on the sum of associated factors. RESULTS: We evaluated 23,025 opioid-naïve women and 25,046 sedative-hypnotic-naïve women. We found that 17,174 opioid-naïve women filled a peri-operative opioid prescription, and of those, 2962 (17.2%) became opioid NPUs post-operatively. Additionally, 9426 sedative-hypnotic-naïve women filled a peri-operative sedative-hypnotic prescription, and of those, 1612 (17.1%) became sedative-hypnotic NPUs. Development of new persistent sedative-hypnotic use was associated with age ≤ 49 [OR 1.77 (95% CI 1.40-2.24)] and age 50-64 [1.60 (1.27-2.03)] compared to age ≥ 65; Medicaid insurance [2.34 (1.40-3.90)]; southern residence [1.42 (1.22-1.64)]; breast cancer diagnosis [2.24 (1.28-3.91)]; and chemotherapy [2.17 (1.94-2.42)]. Risk of NPU increased with higher risk score. Women with ≥ 3 of these risk factors were three times more likely to become sedative-hypnotic NPUs than patients with 0 or 1 factors [2.94 (2.51-3.43)]. Comparable findings were seen regarding new persistent opioid use. CONCLUSION: Women who have M + R are at risk of developing both new persistent opioid and new persistent sedative-hypnotic use. A patient's risk of becoming an NPU increases as their number of risk factors increases. Non-pharmacologic strategies are needed to manage pain and anxiety following cancer-related surgery.

RESUMEN

Purpose To compare the effectiveness of personalized treatment for small (≤4 cm) renal tumors versus routine partial nephrectomy (PN), accounting for various competing causes of mortality. Materials and Methods A state-transition microsimulation model was constructed to compare life expectancy of management strategies for small renal tumors by using 1 000 000 simulations in the following ways: routine PN or personalized treatment involving percutaneous ablation for risk factors for worsening chronic kidney disease (CKD), and otherwise PN; biopsy, with triage of renal cell carcinoma (RCC) to PN or ablation depending on risk factors for worsening CKD; active surveillance for growth; and active surveillance when MRI findings are indicative of papillary RCC. Transition probabilities were incorporated from the literature. Effects of parameter variability were assessed in sensitivity analysis. Results In patients of all ages with normal renal function, routine PN yielded the longest life expectancy (eg, 0.67 years in 65-year-old men with nephrometry score [NS] of 4). Otherwise, personalized strategies extended life expectancy versus routine PN: in CKD stages 2 or 3a, moderate or high NS, and no comorbidities, MRI guidance for active surveillance extended life expectancy (eg, 2.60 years for MRI vs PN in CKD 3a, NS 10); and with Charlson comorbidity index of 1 or more, biopsy or active surveillance for growth extended life expectancy (eg, 2.70 years for surveillance for growth in CKD 3a, NS 10). CKD 3b was most effectively managed by using MRI to help predict papillary RCC for surveillance. Conclusion For patients with chronic kidney disease and small renal tumors, personalized treatment selection likely extends life expectancy. © RSNA, 2019 Online supplemental material is available for this article.

RESUMEN

Background: Stage T1a renal cell carcinoma (RCC) (tumors <4 cm) is usually curable. Nephron-sparing partial nephrectomy (PN) has replaced radical nephrectomy (RN) as the standard of care for these tumors. Radical nephrectomy remains the first alternative treatment option, whereas percutaneous ablation (PA), a newer, nonsurgical treatment, is recommended less strongly because of the relative paucity of comparative PA data. Objective: To compare PA, PN, and RN outcomes. Design: Observational cohort analysis using inverse probability of treatment-weighted propensity scores. Setting: Population-based SEER (Surveillance, Epidemiology, and End Results) cancer registry data linked to Medicare claims. Patients: Persons aged 66 years or older who received treatment for T1a RCC between 2006 and 2011. Interventions: PA versus PN and RN. Measurements: RCC-specific and overall survival, 30- and 365-day postintervention complications. Results: 4310 patients were followed for a median of 52 months for overall survival and 42 months for RCC-specific survival. After PA versus PN, the 5-year RCC-specific survival rate was 95% (95% CI, 93% to 98%) versus 98% (CI, 96% to 99%); after PA versus RN, 96% (CI, 94% to 98%) versus 95% (CI, 93% to 96%). After PA versus PN, the 5-year overall survival rate was 77% (CI, 74% to 81%) versus 86% (CI, 84% to 88%); after PA versus RN, 74% (CI, 71% to 78%) versus 75% (CI, 73% to 77%). Cumulative rates of renal insufficiency 31 to 365 days after PA, PN, and RN were 11% (CI, 8% to 14%), 9% (CI, 8% to 10%), and 18% (CI, 17% to 20%), respectively. Rates of nonurologic complications within 30 days after PA, PN, and RN were 6% (CI, 4% to 9%), 29% (CI, 27% to 30%), and 30% (CI, 28% to 32%), respectively. Ten percent of patients in the PN group had intraoperative conversion to RN. Seven percent of patients in the PA group received additional PA within 1 year of treatment. Limitations: Analysis of observational data may have been affected by residual confounding by provider or from selection bias toward younger, healthier patients in the PN group. Findings from this older study population are probably less applicable to younger patients. Use of SEER-Medicare linked files prevented analysis of patients who received treatment after 2011, possibly reducing generalizability to the newest PA, PN, and RN techniques. Conclusion: For well-selected older adults with T1a RCC, PA may result in oncologic outcomes similar to those of RN, but with less long-term renal insufficiency and markedly fewer periprocedural complications. Compared with PN, PA may be associated with slightly shorter RCC-specific survival but fewer periprocedural complications.

RESUMEN

PURPOSE: During ongoing controversies about mammography screening, many investigators have stated that performance improvements in screening mammography may mitigate concerns about harms. However, there have been few attempts to quantify performance improvements required to recommend mammography screening. Based on USPSTF benchmarks, we utilized revealed preference methods to ascertain quantitative thresholds at which screening mammography would be recommended beyond biennial screening in women 50 and older. METHODS: Benefits of routine screening mammography (breast cancer deaths averted) were from published USPSTF meta-analyses. Potential harms (10-year cumulative probability of at least one false-positive) were from published Breast Cancer Surveillance Consortium estimates. We identified the implicit threshold (benefit/harm ratio) to recommend biennial screening starting at age 50. Using this threshold, we ascertained reductions of false-positives required to recommend more frequent screening and screening initiation under age 50 using revealed preference analyses. RESULTS: Using USPSTF implied benefit/harm ratio, routine biennial screening would be recommended starting at 40 if false-positives declined by at least 62%. Reductions of false-positive proportions of 74% would be required to recommend annual screening starting at 40 and reductions of false-positive proportions of 31% would be required to support annual screening starting at 50. CONCLUSIONS: Using USPSTF revealed preferences, 31-74% reductions in false-positives would be required to recommend mammography screening beyond biennial screening starting at age 50. Widespread implementation of tomosynthesis and reducing recall rates to the lower end of recommended recall rates (5-12%) would provide support for expanding screening beyond biennial screening in women age 50.

RESUMEN

BACKGROUND: Several organizations have developed frameworks to systematically assess the value of new drugs. These organizations include the American Society of Clinical Oncology (ASCO), the European Society for Medical Oncology (ESMO), the Institute for Clinical and Economic Review (ICER), and the National Comprehensive Cancer Network (NCCN). OBJECTIVES: To understand the extent to which these four tools can facilitate value-based treatment decisions in oncology. METHODS: In this pilot study, eight panelists conducted value assessments of five advanced lung cancer drugs using the ASCO, ESMO, and ICER frameworks. The panelists received instructions and published clinical data required to complete the assessments. Published NCCN framework scores were abstracted. The Kendall's W coefficient was used to measure convergent validity among the four frameworks. Intraclass correlation coefficients were used to measure inter-rater reliability among the ASCO, ESMO, and ICER frameworks. Sensitivity analyses were conducted. RESULTS: Drugs were ranked similarly by the four frameworks, with Kendall's W of 0.703 (P = 0.006) across all the four frameworks. Pairwise, Kendall's W was the highest for ESMO-ICER (W = 0.974; P = 0.007) and ASCO-NCCN (W = 0.944; P = 0.022) and the lowest for ICER-NCCN (W = 0.647; P = 0.315) and ESMO-NCCN (W = 0.611; P = 0.360). Intraclass correlation coefficients (confidence interval [CI]) for the ASCO, ESMO, and ICER frameworks were 0.786 (95% CI 0.517-0.970), 0.804 (95% CI 0.545-0.973), and 0.281 (95% CI 0.055-0.799), respectively. When scores were rescaled to 0 to 100, the ICER framework provided the narrowest band of scores. CONCLUSIONS: The ASCO, ESMO, ICER, and NCCN frameworks demonstrated convergent validity, despite differences in conceptual approaches used. The ASCO inter-rater reliability was high, although potentially at the cost of user burden. The ICER inter-rater reliability was poor, possibly because of its failure to distinguish differential value among the sample of drugs tested. Refinements of all frameworks should continue on the basis of further testing and stakeholder feedback.

RESUMEN

BACKGROUND: Expert groups and national guidelines recommend individualized decision making about screening mammography for women in their 40s at low-to-average risk of breast cancer. We created Breast Screening Decisions (BSD), a personalized, web-based decision aid, to help women decide when to start and how often to have routine screening mammograms. We evaluated BSD in a large, prospective pilot trial of women and their clinicians. METHODS: Women ages 40-49 were invited to use BSD before a scheduled preventive care visit. One month post-visit, users were asked about decisional conflict, knowledge, perceptions and worry about breast cancer and screening. They were also asked whether they had a screening mammogram since their visit, scheduled an appointment for a screening mammogram, or if they were planning to schedule an appointment within the next six months. Women who responded "no" to each of these successive questions were considered to have no plan for a screening mammogram within the next 6 months, unless they explicitly stated that they were unsure about screening mammography. Clinicians were surveyed regarding mammography discussions and perceived patient knowledge and anxiety. RESULTS: Of 1,100 women invited to use BSD, 253 accessed the website, and 168 were eligible to participate in the pilot study. One-fifth had a family history of breast cancer, and at least 76% had any prior mammogram. At follow-up, 88% of BSD users reported discussing mammography at their visit, and 77% said they had a screening mammogram since the visit or that they made or were planning to make a screening mammogram appointment. The average decisional conflict score was 22.5, within the threshold for implementing decisions. Decisional conflict scores were lowest in women who said that they had or planned to have a mammogram (mean 21.4, 95% CI 18.3-24.6), higher in those who did not (mean 24.8, 95% CI 19.2-30.5), and highest in those who were unsure (mean 31.5, 95% CI 13.9-49.1). Most BSD users expressed accurate perceptions of their breast cancer risk and the benefits and limitations of screening. CONCLUSIONS: A web-based decision aid may support informed, individualized decisions about screening mammography and facilitate discussions about screening between women in their 40s and their clinicians.

RESUMEN

OBJECTIVES: To characterize patterns of imaging surveillance after nephrectomy in a population-based cohort of older patients with kidney cancer. PATIENTS AND METHODS: Using the Surveillance, Epidemiology and End Results (SEER)-Medicare database, we identified patients aged ≥ 66 years who underwent partial or radical nephrectomy for localized kidney cancer diagnosed between 2000 and 2009. Primary outcomes were chest imaging (X-ray or computed tomography [CT]) and abdominal imaging (CT, MRI or ultrasonography) in Medicare claims from 4 to 36 months after surgery. We estimated the frequency of imaging in three time periods (postoperative months 4-12, 13-24, 25-36), stratified by tumour stage. Repeated-measures logistic regression was used to identify the patient and disease characteristics associated with imaging. RESULTS: Rates of chest imaging were 65-80%, with chest X-ray surpassing CT in each time period. Rates of abdominal imaging were 58-76%, and cross-sectional imaging was more common than ultrasonography in each time period. Use of cross-sectional chest and abdominal imaging increased over time, while the use of chest X-ray decreased (P < 0.01). Ultrasonography use remained stable for patients with T1 and T2 disease, but the rate of use decreased in patients with T3 disease (P < 0.05). Rates of chest and abdominal imaging increased with tumour stage (P < 0.001). CONCLUSIONS: Patterns of imaging suggest possible overuse in patients at low risk of recurrence and underuse in those at greater risk. New surveillance imaging guidelines may reduce unwarranted variability and promote risk-based, cost-effective management after nephrectomy.

RESUMEN

BACKGROUND: Despite advantages in terms of cancer control and organ preservation, the benefits of chemotherapy and radiation therapy (CTRT) may be offset by potentially severe treatment-related toxicities, particularly in older patients. The objectives of this study were to assess the types and frequencies of toxicities in older adults with locally or regionally advanced head and neck squamous cell carcinoma (HNSCC) who were receiving either primary CTRT or radiation therapy (RT) alone. METHODS: With Surveillance, Epidemiology, and End Results cancer registry data linked with Medicare claims, patients who were 66 years old or older with locally advanced HNSCC, were diagnosed from 2001 to 2009, and received CTRT or RT alone were identified. Differences in the frequency of toxicity-related hospital admissions and emergency room visits as well as feeding tube use were examined, and controlling for demographic and disease characteristics, this study estimated the impact of chemotherapy on the likelihood of toxicity. RESULTS: Among patients who received CTRT (n = 1502), 62% had a treatment-related toxicity, whereas 46% of patients who received RT alone (n = 775) did. When the study controlled for demographic and disease characteristics, CTRT patients were twice as likely to experience an acute toxicity in comparison with their RT-only peers. Fifty-five percent of CTRT patients had a feeding tube placed during or after treatment, whereas 28% of the RT-only group did. CONCLUSIONS: In this population-based cohort of older adults with HNSCC, the rates of acute toxicities and feeding tube use in patients receiving CTRT were considerable. It is possible that for certain older patients, the potential benefit of adding chemotherapy to RT does not outweigh the harms of this combined-modality therapy.

RESUMEN

BACKGROUND: Identifying unwarranted variation in health care can highlight opportunities to reduce harm. One often discretionary process in oncology is use of implanted ports to administer intravenous chemotherapy. While there are benefits, ports carry risks. This study's objective was to assess provider-driven variation in port use among cancer patients receiving chemotherapy. RESEARCH DESIGN: Retrospective assessment using population-based SEER-Medicare data to assess differences in port use across health care providers of older adults with cancer. Participants included over 18,000 patients ages 66 and older diagnosed with breast, colorectal, lung, or pancreatic cancer in 2005-2007, treated by approximately 2900 providers. We identified port use for patients receiving treatment from hospital outpatient facilities versus physicians' offices. Our main analysis assessed the likelihood of a patient receiving a port given port use by the provider's last patient. For a subset of high-use providers, we examined individual provider-level variation by estimating the risk-adjusted likelihood of insertion. RESULTS: Patients receiving chemotherapy in hospital outpatient facilities were significantly less likely to receive a port than those treated in physicians' offices, with adjusted odds ratios (AOR) varying from 0.50 to 0.75 across cancer sites. Implanting a port was associated with increased likelihood of port insertion in the provider's next patient (AOR varied from 1.71 to 2.25). Significant between-provider variation was found among providers with at least 10 patients. CONCLUSIONS: Our findings support the idea that there is provider-driven variation in the use of ports for chemotherapy administration. This variation highlights an opportunity to standardize practice and reduce unnecessary use.

RESUMEN

BACKGROUND: Facing rising incidence of basal cell carcinoma (BCC) and increasing pressure to contain health care spending, physicians need to contemplate cost-effective paradigms for managing BCC. OBJECTIVE: We sought to perform a cost analysis comparing the traditional BCC management scheme with a simplified detect-and-treat scheme that eliminates the biopsy before initiating definitive treatment. METHODS: A decision analytic model was developed to compare the costs of traditional BCC management with the detect-and-treat scheme, under which qualifying lesions diagnosed clinically were either treated with shave removal or referred to Mohs micrographic surgery for on-site histologic check. Values for model parameters were based on literature and our institutional data analysis. Costs were based on 2014 Medicare fee schedule. RESULTS: The average cost per lesion with detect-and-treat scheme was $449 for non-Mohs micrographic surgery-indicated lesions (vs $566 with traditional management, $117 in savings) and $819 for Mohs micrographic surgery-indicated lesions (vs $864 with traditional management, $45 in savings). The combined weighted average savings per case was $95 (15% of total average cost). Conclusions were similar under various plausible scenarios. LIMITATIONS: Model parameter values may vary based on individual practices. CONCLUSIONS: A simplified management strategy eliminating routine pretreatment biopsy can reduce BCC treatment cost without compromising quality of care.

RESUMEN

BACKGROUND: Survivors of head and neck squamous cell carcinoma (HNSCC) face excess mortality from multiple causes. METHODS: We used the population-based Surveillance, Epidemiology, and End Results (SEER) cancer registry data to evaluate the causes of death in patients with nonmetastatic HNSCC diagnosed between 1992 and 2005 who survived at least 3 years from diagnosis (long-term survivors). We used competing-risks proportional hazards regression to estimate probabilities of death from causes: HNSCC, second primary malignancy (SPM) excluding HNSCC, cardiovascular disease, and other causes. RESULTS: We identified 35,958 three-year survivors of HNSCC with a median age at diagnosis of 60 years (range = 18-100 years) and a median follow-up of 7.7 years (range = 3-18 years). There were 13,120 deaths during the study period. Death from any cause at 5 and 10 years was 15.4% (95% confidence interval [CI] = 15.0%-15.8%) and 41.0% (95% CI = 40.4%-41.6%), respectively. There were 3852 HNSCC deaths including both primary and subsequent head and neck tumors. The risk of death from HNSCC was greater in patients with nasopharynx or hypopharynx cancer and in patients with locally advanced disease. SPM was the leading cause of non-HNSCC death, and the most common sites of SPM death were lung (53%), esophagus (10%), and colorectal (5%) cancer. CONCLUSIONS: Many long-term HNSCC survivors die from cancers other than HNSCC and from noncancer causes. Routine follow-up care for HNSCC survivors should expand beyond surveillance for recurrent and new head and neck cancers.

RESUMEN

PURPOSE: Men are diagnosed with bladder cancer at 3 times the rate of women. However, women present with advanced disease and have poorer survival, suggesting delays in bladder cancer diagnosis. Hematuria is the presenting symptom in most cases. We assessed gender differences in hematuria evaluation in older adults with bladder cancer. MATERIALS AND METHODS: Using the SEER (Surveillance, Epidemiology and End Results) cancer registry linked with Medicare claims we identified Medicare beneficiaries 66 years old or older diagnosed with bladder cancer between 2000 and 2007 with a claim for hematuria in the year before diagnosis. We examined the impact of gender, and demographic and clinical factors on time from initial hematuria claim to urology visit and on time from initial hematuria claim to hematuria evaluation, including cystoscopy, upper urinary tract imaging and urine cytology. RESULTS: Of 35,646 patients with a hematuria claim in the year preceding bladder cancer diagnosis 97% had a urology visit claim. Mean time to urology visit was 27 days (range 0 to 377). Time to urology visit was longer for women than for men (adjusted HR 0.9, 95% CI 0.87-0.92). Women were more likely to undergo delayed (after greater than 30 days) hematuria evaluation (adjusted OR 1.13, 95% CI 1.07-1.21). CONCLUSIONS: We observed longer time to a urology visit for women than for men presenting with hematuria. These findings may explain stage differences in bladder cancer diagnosis and inform efforts to decrease gender disparities in bladder cancer stage and outcomes.

RESUMEN

Importance: The OlympiA trial found that 1 year of adjuvant olaparib therapy can improve distant disease-free survival and overall survival from early-stage breast cancer in patients with a germline BRCA1/2 mutation. However, olaparib, an oral poly-adenosine diphosphate ribose polymerase inhibitor, is estimated to cost approximately $14 000 per month in the US. Objective: To estimate the incremental cost-effectiveness of adjuvant olaparib compared with no olaparib in eligible patients. Design, Setting, and Participants: In an economic evaluation from a health care system perspective, the cost-effectiveness of adjuvant olaparib was analyzed using a Markov state-transition model. The model simulated costs and lifetime health outcomes of 42-year-old women with high-risk early-stage breast cancer and a known BRCA1/2 mutation who completed definitive primary therapy and neoadjuvant or adjuvant systemic therapy. The study was conducted from August 2021 to July 2023. The effectiveness of olaparib was based on the findings of the OlympiA randomized clinical trial, and other model parameters were identified from the literature. The model was calibrated to the 1-, 2-, 3-, and 4-year distant disease-free and overall survival observed in the OlympiA trial, and olaparib was assumed to reduce the risk of distant recurrence only in the first 4 years. Exposure: One year of adjuvant olaparib or no adjuvant olaparib. Main Outcome and Measure: Incremental cost-effectiveness ratio (ICER) in 2021 US dollars per quality-adjusted life-year (QALY) gained. All outcomes were discounted by 3% annually. Results: In the base case, adjuvant olaparib was associated with a 1.25-year increase in life expectancy and a 1.20-QALY increase at an incremental cost of $133 133 compared with no olaparib. The resulting ICER was approximately $111 000 per QALY gained. At a willingness-to-pay threshold of $150 000 per QALY, olaparib was cost-effective at its 2021 price and in more than 92% of simulations in probabilistic sensitivity analysis. The results were sensitive to assumptions about the effectiveness of olaparib and quality of life for patients with no disease recurrence. Conclusions and Relevance: In this study, from a US health care system perspective, adjuvant olaparib was a cost-effective option for patients with high-risk, early-stage breast cancer and a germline BRCA1/2 mutation.

RESUMEN

PURPOSE: Oral anticancer drugs (OACDs) have become increasingly prevalent over the past decade. OACD prescriptions require coordination between payers and providers, which can delay drug receipt. We examined the association between insurance type, pursuit of copayment assistance, pursuit of prior authorization (PA), and time to receipt (TTR) for new OACD prescriptions. METHODS: We prospectively collected data on new OACD prescriptions for adult oncology patients from January 1, 2018, to December 31, 2019, including demographic and clinical characteristics, insurance type, and pursuit of PA and copayment assistance. TTR was defined as the number of days from prescription to OACD receipt. We summarized TTR using cumulative incidence and compared TTR by insurance type, pursuit of copayment assistance, and PA activity using the log-rank test. RESULTS: Our cohort of 1,024 patients was 53% male, and 40% were younger than 65. Twenty-six percent had commercial insurance only, 16% had Medicaid only, and 59% had Medicare with or without additional insurance. Eighty-six percent of prescriptions were successfully received. Across all prescriptions, 69% involved PA activity, and 21% involved the copayment assistance process. In unadjusted analyses, prescriptions involving the copayment assistance process had longer TTR compared with those not involving assistance (log-rank P value = .005) and OACDs covered by Medicare/commercial insurance had a longer TTR compared with Medicaid (log-rank P value = .006). The PA process was not associated with TTR (log-rank P value = .124). CONCLUSION: The process for obtaining OACDs is complex. The copayment assistance process and Medicare/commercial insurance are associated with delayed TTR. New policies are needed to reduce time to OACD receipt.
