RESUMEN
INTRODUCTION: This real-world, cross-sectional study compared sociodemographic, clinical and treatment characteristics, and patient-reported outcomes (PROs) among racial/ethnic groups in patients with atopic dermatitis (AD) who are candidates for systemic therapy. METHODS: This study included adults with dermatologist- or dermatology practitioner-diagnosed AD enrolled in the CorEvitas AD Registry (July 2020-July 2021). All patients initiated systemic therapy within 12 months prior to or at enrollment or had moderate-to-severe AD (vIGA-AD® ≥ 3 and Eczema Area and Severity Index [EASI] ≥ 12) at enrollment. Patients were categorized into five mutually exclusive racial/ethnic groups: non-Hispanic White, Black, Asian, Other/Multiracial, and Hispanic (any race). Patient, clinical, and treatment characteristics were captured at enrollment. Differences in means or proportions of characteristics among racial/ethnic groups were descriptively summarized using effect sizes. Adjusted prevalence ratios and mean differences were estimated (White race/ethnicity group as the reference category) with 95% confidence intervals (CI). RESULTS: Among 1288 patients, 64% (n = 822) were White, 13% (n = 167) Black, 10% (n = 129) Asian, 8% (n = 97) Hispanic, and 6% (n = 73) Other/Multiracial. In adjusted analyses, statistically more severe EASI lichenification was noted among Black compared with White patients at the head and neck (mean difference, 0.21, [95% CI 0.06, 0.36]; p = 0.01), trunk (0.32, [0.17, 0.47]; p < 0.001), upper extremities (0.27, [0.09, 0.44]; p = 0.008), and lower extremities (0.39, [0.21, 0.57]; p < 0.001). Statistically more severe EASI lichenification was observed among Asian vs White patients in certain areas (mean difference, head and neck, 0.22 [0.04, 0.39], p = 0.01; trunk, 0.25 [0.07, 0.43], p < 0.001; lower extremities, 0.22 [0.01, 0.43], p < 0.001) and SCORing for AD lichenification (mean difference: 0.34 [0.15, 0.52]; p < 0.001). Significantly higher mean pruritus over the past 7 days for Black (mean difference: 0.63 [0.01, 1.26] and Hispanic patients (0.60 [0.11, 1.09]; p = 0.03) vs White patients was observed. Among AD clinical features, the prevalence of facial erythema was significantly lower among Black compared with White patients (prevalence ratio = 0.38, [0.22, 0.67]; p = 0.007). CONCLUSION: Racial/ethnic differences exist in sociodemographic, clinical and treatment characteristics, disease severity, and PROs among real-world AD patients who are candidates for systemic therapy. Recognizing these variations may be of critical importance for dermatologists for the design and delivery of targeted/personalized medicine approaches.
RESUMEN
BACKGROUND: Psoriasis patients with poor therapeutic response to multiple biologic agents are not well-characterized. OBJECTIVE: To describe the characteristics associated with development of multiple biologic failure (MBF) versus good clinical response (GR) to the first biologic. METHODS: This prospective cohort analysis evaluated patients in the multicenter CorEvitas Psoriasis Registry who initiated their first biologic between 2015 and 2020 and were followed for ≥24 months. Multivariable logistic regression identified sociodemographic, clinical, and patient-reported outcomes that differed between MBF (discontinued ≥2 biologics of different classes, each used for ≥90 days, due to inadequate efficacy) and GR (continued use of first biologic for ≥2 years) patients. RESULTS: One thousand thirty-nine patients were analyzed (490 GR [47.2%], 65 MBF [6.3%]). Female sex, shorter psoriasis duration, earlier year of biologic initiation, prior nonbiologic systemic therapy use, history of hyperlipidemia, and Medicaid insurance were significantly associated with MBF, though the latter 2 variables exhibited wider confidence intervals, indicating a lower level of support. The first-to-second biologic sequence most observed with MBF was Tumor necrosis factor-α inhibitor to IL-17 inhibitor use. LIMITATIONS: Biologic adherence between visits was not evaluated. CONCLUSION: Approximately 6% of psoriasis patients met MBF criteria. The results identify characteristics associated with MBF that may distinguish patients warranting more frequent follow-up.
RESUMEN
INTRODUCTION: Guselkumab is approved for the treatment of both moderate-to-severe plaque psoriasis and active psoriatic arthritis (PsA) in the USA. However, little is known about patients initiating guselkumab in a real-world setting. The objective of this study was to describe baseline characteristics among patients with plaque psoriasis who initiated guselkumab at or after enrollment in CorEvitas' Psoriasis Registry. METHODS: Adult patients who initiated guselkumab in the Psoriasis Registry between July 18, 2017 and November 6, 2018 were included. Demographics, disease characteristics, and patient-reported outcome measures (PROMs) were assessed at the time of guselkumab initiation (baseline). Patients with psoriasis were stratified according to the number of previously received biologics (0 to 4+) for comparison. A subset of patients with psoriasis and concomitant dermatologist-diagnosed PsA were stratified into biologic-naïve and biologic-experienced groups. RESULTS: Among 687 patients with psoriasis who initiated guselkumab, biologic-naïve patients and those with four or more prior biologics had the most severe disease and the worst PROM scores at baseline. Among 251 patients with concomitant dermatologist-diagnosed PsA, biologic-naïve patients had more severe disease and worse PROM scores than biologic-experienced patients. CONCLUSIONS: These findings highlight important differences in baseline characteristics according to biologic experience among patients with plaque psoriasis with or without concomitant PsA initiating guselkumab in a real-world setting.
RESUMEN
BACKGROUND: Given that media coverage can shape healthcare expectations, it is essential that we understand how the media frames "personalized medicine" (PM) in oncology, and whether information about unproven technologies is widely disseminated. METHODS: We conducted a content analysis of 396 news reports related to cancer and PM published between 1 January 1998 and 31 December 2011. Two coders independently coded all the reports using a pre-defined framework. Determination of coverage of "standard" and "non-standard" therapies and tests was made by comparing the media print/broadcast date to the date of Federal Drug Administration approval or incorporation into clinical guidelines. RESULTS: Although the term "personalized medicine" appeared in all reports, it was clearly defined only 27% of the time. Stories more frequently reported PM benefits than challenges (96% vs. 48%, p < 0.001). Commonly reported benefits included improved treatment (89%), prediction of side effects (30%), disease risk prediction (33%), and lower cost (19%). Commonly reported challenges included high cost (28%), potential for discrimination (29%), and concerns over privacy and regulation (21%). Coverage of inherited DNA testing was more common than coverage of tumor testing (79% vs. 25%, p < 0.001). Media reports of standard tests and treatments were common; however, 8% included information about non-standard technologies, such as experimental medications and gene therapy. CONCLUSION: Confusion about personalized cancer medicine may be exacerbated by media reports that fail to clearly define the term. While most media stories reported on standard tests and treatments, an emphasis on the benefits of PM may lead to unrealistic expectations for cancer genomic care.
RESUMEN
BACKGROUND: Understanding the sources of variation in the use of high-cost technologies is important for developing effective strategies to control costs of care. Palliative radiation therapy (RT) is a discretionary treatment and its use may vary based on patient and clinician factors. METHODS: Using data from the SEER-Medicare linked database, we identified patients diagnosed with metastatic lung, prostate, breast, and colorectal cancers in 2010 through 2015 who received RT, and the radiation oncologists who treated them. The costs of radiation services for each patient over a 90-day episode were calculated, and radiation oncologists were assigned to cost quintiles. The use of advanced technologies (eg, intensity-modulated radiation, stereotactic RT) and the number of RT treatments (eg, any site, bone only) were identified. Multivariable random-effects models were constructed to estimate the proportion of variation in the use of advanced technologies and extended fractionation (>10 fractions) that could be explained by patient fixed effects versus physician random effects. RESULTS: We identified 37,361 patients with metastatic lung cancer, 3,684 with metastatic breast cancer, 5,323 with metastatic prostate cancer, and 8,726 with metastatic colorectal cancer, with 34%, 27%, 22%, and 9% receiving RT within the first year, respectively. The use of advanced technologies and extended fractionation was associated with higher costs of care. Compared with the patient case-mix, physician variation accounted for a larger proportion of the variation in the use of advanced technologies for palliative RT and the use of extended fractionation. CONCLUSIONS: Differences in radiation oncologists' practice and choices, rather than differences in patient case-mix, accounted for a greater proportion of the variation in the use of advanced technologies and high-cost radiation services.

To compare drug survival of ixekizumab to other IL-17 inhibitors (IL-17i) and TNF inhibitors (TNFi) among patients with psoriasis (PsO) in a real-world setting. Participants included adult PsO patients enrolled in the Corrona Psoriasis Registry who initiated ixekizumab, TNFi, or other IL-17i between 16 March 2016 to 10 August 2019 and completed ≥1 follow-up visit. Multivariable adjusted hazard ratios (HR) were calculated to estimate the risk for drug discontinuation in the ixekizumab group relative to the other drugs. Among the 1604 drug initiations, 552 initiated ixekizumab, 450 initiated TNFi, and 602 initiated other IL-17i. Mean age was 51 years, 49% were women, and 52% were obese (BMI > 30). Ixekizumab patients had a higher proportion of patients with PASI >12 at drug initiation (24%) than TNFi (15%) and other IL-17i (19%). Over a median of 11 months of follow-up, 723/1604 (45%) drug discontinuations occurred. Persistence of ixekizumab, TNFi, and other IL-17i at 24-months were 68%, 33%, and 46%, among biologic-naïve patients (n = 543), and 46%, 23%, and 36%, for biologic-experienced patients (n = 1061), respectively. Ixekizumab patients had a 64% lower risk of discontinuation vs TNFi (HR = 0.36; 95% CI 0.27-0.47) and a 31% lower risk vs other IL-17i (HR = 0.69, 95% CI 0.55-0.87) after adjustment for biologic experience and other covariates. HRs were similar when limited to patients with moderate-to-severe PsO (BSA > 3, PASI > 3, and IGA > 1, n = 1076) at initiation. In our study of real-world patients with PsO, initiators of ixekizumab had more prolonged drug survival than both initiators of TNFi and other IL-17i up to 2 years of follow-up.

INTRODUCTION: Data on the characteristics of apremilast patients in real-world settings are limited. We assessed the demographics and disease characteristics of apremilast-treated patients in the Corrona Psoriasis Registry overall and by treatment history. METHODS: The Corrona Psoriasis Registry is a large, independent, prospective, observational registry of adult patients (age ≥ 18 years) who initiate an eligible systemic medication for treatment of psoriasis at or after enrollment (incident users) or within 12 months before enrollment (prevalent users). The current analyses included psoriasis patients enrolled in the Corrona Psoriasis Registry between April 1, 2015, and January 7, 2018. Patients were adults (age ≥ 18 years) with psoriasis who were enrolled between April 1, 2015, and January 7, 2018 and initiated apremilast at the time of registry enrollment or a subsequent visit (incident users) or within the 12 months prior to registry enrollment (prevalent users). Patient characteristics were evaluated descriptively at the index date, defined as the enrollment date for prevalent users and the visit when apremilast was initiated for incident users. RESULTS: Among 660 patients who initiated apremilast at registry enrollment or a visit thereafter, psoriatic arthritis, hypertension, and hyperlipidemia were common. There were more systemic-experienced (61.4%) versus systemic-naive (38.6%) patients; 43.8% had prior biologic exposure. Most patients were not receiving concomitant systemic treatment (70.2%); 27.4% were receiving concomitant biologic therapy. Most patients had mild or moderate disease (psoriasis-involved body surface area ≤ 10% [76.0%], Investigator Global Assessment ≤ 3 [88.3%], Psoriasis Area and Severity Index ≤ 10 [84.5%]). Dermatologist-reported psoriatic arthritis was present in 47.0% of patients; 33.9% of patients had a Psoriasis Epidemiology Screening Tool score of ≥ 3, suggestive of psoriatic arthritis. Systemic-experienced apremilast patients had higher rates of obesity and comorbidities and experienced a greater impact on quality of life (mean Dermatology Life Quality Index, 7.3 vs. 6.5) versus systemic-naive patients. CONCLUSION: In this real-world observational study of apremilast users in the Corrona Psoriasis Registry, most patients had less-severe disease and higher rates of prior exposure to biologic treatments compared with patients with moderate-to-severe psoriasis enrolled in phase 3 clinical studies.
RESUMEN
OBJECTIVE: Germline genetic testing is crucial to the care of ovarian cancer patients, and as part of the guideline-based care for ovarian cancer patient's adherence to this recommendation has been low. We sought to determine whether embedding a genetic counselor (GC) within a medical and gynecologic oncology clinic would increase testing rates and improve the timeliness of testing. METHODS: Prospective cohort study of 358 ovarian cancer patients seen by medical and gynecologic oncologists between 2013 and 2015. Rates of referrals, completion of counseling, and genetic testing and timeliness of counseling were abstracted before and after a GC was embedded in the clinic in 2014. An additional year of data (2015) was collected to evaluate sustainability of the intervention. RESULTS: Between 2013 and 2015, 88-92% of women were referred for genetic testing, but in 2013 only 66% completed counseling and 61% were tested. After a GC was embedded in the clinic in 2014, more than 80% of referred women completed counseling and germline genetic testing. Time to genetic counseling also decreased from a median of 107 to 40 days, irrespective of age and cancer family history (p < 0.01). CONCLUSIONS: Embedding a GC into the workflow for ovarian cancer patients is an effective way of improving access to genetic counseling, testing rates, and the timeliness of testing.

BACKGROUND: Although the 21-gene recurrence score (RS) assay is widely used to predict distant recurrence risk and benefit from adjuvant chemotherapy among women with hormone receptor-positive (HR+) breast cancer, the relationship between the RS and isolated locoregional recurrence (iLRR) remains poorly understood. Therefore, we examined the association between the RS and risk of iLRR for women with stage I-II, HR+ breast cancer. METHODS: We identified 1758 women captured in the national prospective Breast Cancer-Collaborative Outcomes Research Database who were diagnosed with stage I-II, HR+ breast cancer from 2006 to 2012, treated with mastectomy or breast-conserving surgery, and received RS testing. Women who received neoadjuvant therapy were excluded. The association between the RS and risk of iLRR was examined using competing risks regression. RESULTS: Overall, 19% of the cohort (n = 329) had a RS ≥25. At median follow-up of 29 months, only 22 iLRR events were observed. Having a RS ≥25 was not associated with a significantly higher risk of iLRR compared to a RS < 25 (hazard ratio 1.14, 95% confidence interval 0.39-3.36, P = 0.81). When limited to women who received adjuvant endocrine therapy without chemotherapy (n = 1199; 68% of the cohort), having a RS ≥25 (n = 74) was significantly associated with a higher risk of iLRR compared to a RS < 25 (hazard ratio 3.66, 95% confidence interval 1.07-12.5, P = 0.04). In this group, increasing RS was associated with greater risk of iLRR (compared to RS < 18, hazard ratio of 1.66, 3.59, and 7.06, respectively, for RS 18-24, 25-30, and ≥ 31; Ptrend = 0.02). CONCLUSIONS: The RS was significantly associated with risk of iLRR in patients who did not receive adjuvant chemotherapy. The utility of the RS in identifying patients who have a low risk of iLRR should be further studied.

BACKGROUND: Among patients diagnosed with stage IA non-small cell lung cancer (NSCLC), the incidence of occult brain metastasis is low, and several professional societies recommend against brain imaging for staging purposes. The goal of this study was to characterize the use of brain imaging among Medicare patients diagnosed with stage IA NSCLC. METHODS: Using data from linked SEER-Medicare claims, we identified patients diagnosed with AJCC 8th edition stage IA NSCLC in 2004 through 2013. Patients were classified as having received brain imaging if they underwent head CT or brain MRI from 1 month before to 3 months after diagnosis. We identified factors associated with receipt of brain imaging using multivariable logistic regression. RESULTS: Among 13,809 patients with stage IA NSCLC, 3,417 (25%) underwent brain imaging at time of diagnosis. The rate of brain imaging increased over time, from 23.5% in 2004 to 28.7% in 2013 (P=.0006). There was significant variation in the use of brain imaging across hospital service areas, with rates ranging from 0% to 64.0%. Factors associated with a greater likelihood of brain imaging included older age (odds ratios [ORs] of 1.16 for 70-74 years, 1.13 for 75-79 years, 1.31 for 80-84 years, and 1.46 for ≥85 years compared with 65-69 years; all P<.05), female sex (OR, 1.09; P<.05), black race (OR 1.23; P<.05), larger tumor size (ORs of 1.23 for 11-20 mm and 1.28 for 21-30 mm tumors vs 1-10 mm tumors; all P<.05), and higher modified Charlson-Deyo comorbidity score (OR, 1.28 for score >1 vs score of 0; P<.05). CONCLUSIONS: Roughly 1 in 4 patients with stage IA NSCLC received brain imaging at the time of diagnosis despite national recommendations against the practice. Although several patient factors are associated with receipt of brain imaging, there is significant geographic variation across the United States. Closer adherence to clinical guidelines is likely to result in more cost-effective care.

Pathogenic sequence variants (PSV) in BRCA1 or BRCA2 (BRCA1/2) are associated with increased risk and severity of prostate cancer. We evaluated whether PSVs in BRCA1/2 were associated with risk of overall prostate cancer or high grade (Gleason 8+) prostate cancer using an international sample of 65 BRCA1 and 171 BRCA2 male PSV carriers with prostate cancer, and 3,388 BRCA1 and 2,880 BRCA2 male PSV carriers without prostate cancer. PSVs in the 3' region of BRCA2 (c.7914+) were significantly associated with elevated risk of prostate cancer compared with reference bin c.1001-c.7913 [HR = 1.78; 95% confidence interval (CI), 1.25-2.52; P = 0.001], as well as elevated risk of Gleason 8+ prostate cancer (HR = 3.11; 95% CI, 1.63-5.95; P = 0.001). c.756-c.1000 was also associated with elevated prostate cancer risk (HR = 2.83; 95% CI, 1.71-4.68; P = 0.00004) and elevated risk of Gleason 8+ prostate cancer (HR = 4.95; 95% CI, 2.12-11.54; P = 0.0002). No genotype-phenotype associations were detected for PSVs in BRCA1. These results demonstrate that specific BRCA2 PSVs may be associated with elevated risk of developing aggressive prostate cancer. SIGNIFICANCE: Aggressive prostate cancer risk in BRCA2 mutation carriers may vary according to the specific BRCA2 mutation inherited by the at-risk individual.

BACKGROUND: Many parents of children with advanced cancer pursue curative goals when cure is no longer possible. To the authors' knowledge, no pediatric studies to date have prospectively evaluated prognosis communication or influences on decision making in poor-prognosis childhood cancer. METHODS: The authors conducted a prospective cohort study at 9 pediatric cancer centers that enrolled 95 parents of children with recurrent or refractory, high-risk neuroblastoma (63% of those who were approached), a condition for which cure rarely is achieved. Parents were surveyed regarding the child's likelihood of cure; their primary goal of care; the child's symptoms, suffering, and quality of life; and regret concerning the last treatment decision. Medical records identified care and treatment decisions. RESULTS: Only 26% of parents recognized that the chance of cure was <25%. When asked to choose a single most important goal of care, approximately 72% chose cure, 10% chose longer life, and 18% chose quality of life. Parents were more likely to prioritize quality of life when they recognized the child's poor prognosis (P = .002). Approximately 41% of parents expressed regret about the most recent treatment decision. Parents were more likely to experience regret if the child had received higher intensity medical care (odds ratio [OR], 3.14; 95% CI, 1.31-7.51), experienced suffering with limited benefit from the most recent treatment (OR, 4.78; 95% CI, 1.16-19.72), or experienced suffering from symptoms (OR, 2.91; 95% CI, 1.18-7.16). CONCLUSIONS: Parents of children with poor-prognosis cancer frequently make decisions based on unrealistic expectations. New strategies for effective prognosis communication are needed.

BACKGROUND: Women with a history of ductal carcinoma in situ (DCIS) are at increased risk for developing a second breast cancer (SBC). A prior meta-analysis of randomized studies of radiotherapy (RT) for DCIS has shown a trend toward increased breast cancer-specific mortality after SBC, but it did not have the power needed to detect a significant difference, due to a limited number of recurrences. This study sought to evaluate the impact of RT for DCIS on mortality after SBC in a larger cohort. PATIENTS AND METHODS: Using the SEER database, 3,407 patients were identified who received breast-conserving therapy with or without RT for primary DCIS in 2000 through 2013 and subsequently developed a stage I-III invasive SBC within the same time period. Fine-Gray competing risk models were used to study the association between receipt of RT and mortality after SBC. RESULTS: Prior RT was found to be associated with higher rates of breast cancer-specific mortality (hazard ratio [HR], 1.70; 95% CI, 1.18-2.45; P=.005), even after controlling for cancer stage. Interaction analysis suggested that this risk trended higher in patients with ipsilateral versus contralateral SBC (HR, 2.07 vs 1.26; P=.16). Furthermore, compared with patients who developed contralateral SBC, those with ipsilateral SBC were younger (P<.001) and more often lacked estrogen receptor expression (P<.001). CONCLUSIONS: Patients who previously received RT for DCIS had higher mortality after developing an invasive SBC than those who did not receive RT. This finding may have implications for initial treatment decisions in the management of DCIS.

BACKGROUND: Most women with advanced epithelial ovarian cancer develop recurrent disease, despite maximal surgical cytoreduction and adjuvant platinum-based chemotherapy. In observational studies, secondary cytoreductive surgery has been associated with improved survival; however its use is controversial, because there are concerns that the improved outcomes may reflect selection bias rather than the superiority of secondary surgery. OBJECTIVE: To compare the overall survival of women with platinum-sensitive recurrent ovarian cancer treated at National Cancer Institute-designated cancer centers who receive secondary surgery vs chemotherapy. STUDY DESIGN: This retrospective cohort study included women from 6 National Cancer Institute-designated cancer centers diagnosed with platinum-sensitive recurrent ovarian cancer between January 1, 2004, and December 31, 2011. The primary outcome was overall survival. Propensity score matching was used to compare similar women who received secondary surgery vs chemotherapy. Additional analyses examined how these findings may be influenced by the prevalence of unobserved confounders at the time of recurrence. RESULTS: Among 626 women, 146 (23%) received secondary surgery and 480 (77%) received chemotherapy. In adjusted analyses, patients who received secondary surgery were younger (P = 0.001), had earlier-stage disease at diagnosis (P = 0.002), and had longer disease-free intervals (P < 0.001) compared with those receiving chemotherapy. In the propensity score-matched groups (n = 244 patients), the median overall survival was 54 months in patients who received secondary surgery and 33 months in those treated with chemotherapy (P < 0.001). Among patients who received secondary surgery, 102 (70%) achieved optimal secondary cytoreduction. There were no significant differences in complication rates between the 2 groups. In sensitivity analyses, the survival advantage associated with secondary surgery could be explained by the presence of more multifocal recurrences (if 4.3 times more common), ascites (if 2.7 times more common), or carcinomatosis (if 2.1 times more common) among patients who received chemotherapy instead of secondary surgery. CONCLUSION: Patients with platinum-sensitive recurrent ovarian cancer who received secondary surgery had favorable surgical characteristics and were likely to have minimal residual disease following secondary surgery. These patients had a superior median overall survival compared with patients who received chemotherapy, although unmeasured confounders may explain this observed difference.

PURPOSE: Increasing use of genomic tumor profiling may blur the line between research and clinical care. We aimed to describe research participants' perspectives on the purpose of genomic tumor profiling research in pediatric oncology. METHODS: We surveyed 45 participants (response rate 85%) in a pilot study of genomic profiling in pediatric solid tumors at four academic cancer centers following return of sequencing results. We defined understanding according to a one-item ("basic") definition (recognizing that the primary purpose was not to improve the patient's treatment) and a four-item ("comprehensive") definition (primary purpose was not to improve patient's treatment; primary purpose was to improve treatment of future patients; there may not be direct medical benefit; most likely result of participation was not increased likelihood of cure). RESULTS: Sixty-eight percent of respondents (30/44) demonstrated basic understanding of the study purpose; 55% (24/44) demonstrated comprehensive understanding. Understanding was more frequently seen in those with higher education and greater genetic knowledge according to basic (81% vs 50%, p=0.05; and 82% vs 46%, p=0.03, respectively) and comprehensive definitions (73% vs 28%, p=0.01; 71% vs 23%, p=0.01). Ninety-three percent of respondents who believed the primary purpose was to improve the patient's care simultaneously stated that the research also aimed to benefit future patients. CONCLUSIONS: Most participants in pediatric tumor profiling research understand that the primary goal of this research is to improve care for future patients, but many express dual goals when participating in sequencing research. Some populations demonstrate increased rates of misunderstanding. Nuanced participant views suggest further work is needed to assess and improve participant understanding, particularly as tumor sequencing moves beyond research into clinical practice.
RESUMEN
PURPOSE: As exome and genome sequencing (ES/GS) enters the clinic, there is an urgent need to understand the psychological effects of test result disclosure. Through a Clinical Sequencing Exploratory Research (CSER), phase 1 (CSER1) Consortium collaboration, we evaluated participants' psychological outcomes across multiple clinical settings. METHODS: We conducted a random effects meta-analysis of state anxiety (Hospital Anxiety and Depression Scale [HADS]/Generalized Anxiety Disorder 7-item), depressive symptoms (HADS/Personal Health Questionnaire 9-item), and multidimensional impact (i.e., test-related distress, uncertainty and positive impact: modified Multidimensional Impact of Cancer Risk Assessment/Feelings About Genomic Testing Results scale). RESULTS: Anxiety and depression did not increase significantly following test result disclosure. Meta-analyses examining mean differences from pre- to postdisclosure revealed an overall trend for a decrease in participants' anxiety. We observed low levels of test-related distress and perceptions of uncertainty in some populations (e.g., pediatric patients) and a wide range of positive responses. CONCLUSION: Our findings across multiple clinical settings suggest no clinically significant psychological harms from the return of ES/GS results. Some populations may experience low levels of test-related distress or greater positive psychological effects. Future research should further investigate the reasons for test-related psychological response variation.

PURPOSE: Spending for patients with advanced cancer is substantial. Past efforts to characterize this spending usually have not included patients with recurrence (who may differ from those with de novo stage IV disease) or described which services drive spending. METHODS: Using SEER-Medicare data from 2008 to 2013, we identified patients with breast, colorectal, and lung cancer with either de novo stage IV or recurrent advanced cancer. Mean spending/patient/month (2012 US dollars) was estimated from 12 months before to 11 months after diagnosis for all services and by the type of service. We describe the absolute difference in mean monthly spending for de novo versus recurrent patients, and we estimate differences after controlling for type of advanced cancer, year of diagnosis, age, sex, comorbidity, and other factors. RESULTS: We identified 54,982 patients with advanced cancer. Before diagnosis, mean monthly spending was higher for recurrent patients (absolute difference: breast, $1,412; colorectal, $3,002; lung, $2,805; all P < .001), whereas after the diagnosis, it was higher for de novo patients (absolute difference: breast, $2,443; colorectal, $4,844; lung, $2,356; all P < .001). Spending differences were driven by inpatient, physician, and hospice services. Across the 2-year period around the advanced cancer diagnosis, adjusted mean monthly spending was higher for de novo versus recurrent patients (spending ratio: breast, 2.39 [95% CI, 2.05 to 2.77]; colorectal, 2.64 [95% CI, 2.31 to 3.01]; lung, 1.46 [95% CI, 1.30 to 1.65]). CONCLUSION: Spending for de novo cancer was greater than spending for recurrent advanced cancer. Understanding the patterns and drivers of spending is necessary to design alternative payment models and to improve value.

PURPOSE: We previously developed and validated informatic algorithms that used International Classification of Diseases 9th revision (ICD9)-based diagnostic and procedure codes to detect the presence and timing of cancer recurrence (the RECUR Algorithms). In 2015, ICD10 replaced ICD9 as the worldwide coding standard. To understand the impact of this transition, we evaluated the performance of the RECUR Algorithms after incorporating ICD10 codes. METHODS: Using publicly available translation tables along with clinician and other expertise, we updated the algorithms to include ICD10 codes as additional input variables. We evaluated the performance of the algorithms using gold standard recurrence measures associated with a contemporary cohort of patients with stage I to III breast, colorectal, and lung (excluding IIIB) cancer and derived performance measures, including the area under the receiver operating curve, average absolute prediction error, and correct classification rate. These values were compared with the performance measures derived from the validation of the original algorithms. RESULTS: A total of 659 colorectal, 280 lung, and 2,053 breast cancer cases were identified. Area under the receiver operating curve derived from the updated algorithms was 89.0% (95% CI, 82.3% to 95.7%), 88.9% (95% CI, 79.3% to 98.2%), and 80.5% (95% CI, 72.8% to 88.2%) for the colorectal, lung, and breast cancer algorithms, respectively. Average absolute prediction errors for recurrence timing were 2.7 (SE, 11.3%), 2.4 (SE, 10.4%), and 5.6 months (SE, 21.8%), respectively, and timing estimates were within 6 months of actual recurrence for more than 80% of colorectal, more than 90% of lung, and more than 50% of breast cancer cases using the updated algorithm. CONCLUSION: Performance measures derived from the updated and original algorithms had overlapping confidence intervals, suggesting that the ICD9 to ICD10 transition did not affect the RECUR Algorithm performance.
