RESUMO
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.

BACKGROUND: Cancer is becoming more of a chronic disease due to improvements in treatment and early detection for multiple cancer sites. To gain insight on increased life expectancy due to these improvements, we quantified trends in the loss in expectation of life (LEL) due to a cancer diagnosis for six cancer sites from 1975 through 2018. METHODS: We focused on patients diagnosed with female breast cancer, chronic myeloid leukemia (CML), colon and rectum cancer, diffuse large B-cell lymphoma (DLBCL), lung cancer, or melanoma between 1975 and 2018 from nine Surveillance, Epidemiology, and End Results cancer registries. Life expectancies for patients with cancer ages 50+ were modeled using flexible parametric survival models. LEL was calculated as the difference between general population life expectancy and life expectancy for patients with cancer. RESULTS: Over 2 million patients were diagnosed with one of the six cancers between 1975 and 2018. Large increases in life expectancy were observed between 1990 and 2010 for female breast, DLBCL, and CML. Patients with colon and rectum cancer and melanoma had more gradual improvements in life expectancy. Lung cancer LEL only began decreasing after 2005. Increases in life expectancy corresponded with decreases in LEL for patients with cancer. CONCLUSIONS: The reported gains in life expectancy largely correspond to progress in the screening, management, and treatment of these six cancers since 1975. IMPACT: LEL provides an important public health perspective on how improvements in treatment and early detection and their impacts on survival translate into changes in cancer patients' life expectancy.

BACKGROUND: Management of localized or recurrent prostate cancer since the 1990s has been based on risk stratification using clinicopathological variables, including Gleason score, T stage (based on digital rectal exam), and prostate-specific antigen (PSA). In this study a novel prognostic test, the Decipher Prostate Genomic Classifier (GC), was used to stratify risk of prostate cancer progression in a US national database of men with prostate cancer. METHODS: Records of prostate cancer cases from participating SEER (Surveillance, Epidemiology, and End Results) program registries, diagnosed during the period from 2010 through 2018, were linked to records of testing with the GC prognostic test. Multivariable analysis was used to quantify the association between GC scores or risk groups and use of definitive local therapy after diagnosis in the GC biopsy-tested cohort and postoperative radiotherapy in the GC-tested cohort as well as adverse pathological findings after prostatectomy. RESULTS: A total of 572â545 patients were included in the analysis, of whom 8927 patients underwent GC testing. GC biopsy-tested patients were more likely to undergo active active surveillance or watchful waiting than untested patients (odds ratio [OR] =2.21, 95% confidence interval [CI] = 2.04 to 2.38, P < .001). The highest use of active surveillance or watchful waiting was for patients with a low-risk GC classification (41%) compared with those with an intermediate- (27%) or high-risk (11%) GC classification (P < .001). Among National Comprehensive Cancer Network patients with low and favorable-intermediate risk, higher GC risk class was associated with greater use of local therapy (OR = 4.79, 95% CI = 3.51 to 6.55, P < .001). Within this subset of patients who were subsequently treated with prostatectomy, high GC risk was associated with harboring adverse pathological findings (OR = 2.94, 95% CI = 1.38 to 6.27, P = .005). Use of radiation after prostatectomy was statistically significantly associated with higher GC risk groups (OR = 2.69, 95% CI = 1.89 to 3.84). CONCLUSIONS: There is a strong association between use of the biopsy GC test and likelihood of conservative management. Higher genomic classifier scores are associated with higher rates of adverse pathology at time of surgery and greater use of postoperative radiotherapy.In this study the Decipher Prostate Genomic Classifier (GC) was used to analyze a US national database of men with prostate cancer. Use of the GC was associated with conservative management (ie, active surveillance). Among men who had high-risk GC scores and then had surgery, there was a 3-fold higher chance of having worrisome findings in surgical specimens.

PURPOSE: The DecisionDx-Melanoma 31-gene expression profile (31-GEP) test is validated to classify cutaneous malignant melanoma (CM) patient risk of recurrence, metastasis, or death as low (class 1A), intermediate (class 1B/2A), or high (class 2B). This study aimed to examine the effect of 31-GEP testing on survival outcomes and confirm the prognostic ability of the 31-GEP at the population level. METHODS: Patients with stage I-III CM with a clinical 31-GEP result between 2016 and 2018 were linked to data from 17 SEER registries (n = 4,687) following registries' operation procedures for linkages. Melanoma-specific survival (MSS) and overall survival (OS) differences by 31-GEP risk category were examined using Kaplan-Meier analysis and the log-rank test. Crude and adjusted hazard ratios (HRs) were calculated using Cox regression model to evaluate variables associated with survival. 31-GEP tested patients were propensity score-matched to a cohort of non-31-GEP tested patients from the SEER database. Robustness of the effect of 31-GEP testing was assessed using resampling. RESULTS: Patients with a 31-GEP class 1A result had higher 3-year MSS and OS than patients with a class 1B/2A or class 2B result (MSS: 99.7% v 97.1% v 89.6%, P < .001; OS: 96.6% v 90.2% v 79.4%, P < .001). A class 2B result was an independent predictor of MSS (HR, 7.00; 95% CI, 2.70 to 18.00) and OS (HR, 2.39; 95% CI, 1.54 to 3.70). 31-GEP testing was associated with a 29% lower MSS mortality (HR, 0.71; 95% CI, 0.53 to 0.94) and 17% lower overall mortality (HR, 0.83; 95% CI, 0.70 to 0.99) relative to untested patients. CONCLUSION: In a population-based, clinically tested melanoma cohort, the 31-GEP stratified patients by their risk of dying from melanoma.

BACKGROUND: This study examines the association between Medicaid enrollment, including through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), and distant stage for three screening-amenable cancers: breast, cervical, and colorectal. METHODS: We use the Surveillance, Epidemiology, and End Results Cancer Registry linked with Medicaid enrollment data to compare patients who were Medicaid insured with patients who were not Medicaid insured. We estimate the likelihood of distant stage at diagnosis using logistic regression. RESULTS: Medicaid enrollment following diagnosis was associated with the highest likelihood of distant stage. Medicaid enrollment through NBCCEDP did not mitigate the likelihood of distant stage disease relative to Medicaid enrollment prior to diagnosis. Non-Hispanic Black patients had a greater likelihood of distant stage breast and colorectal cancer. Residing in higher socioeconomic areas was associated with a lower likelihood of distant stage breast cancer. CONCLUSIONS: Medicaid enrollment prior to diagnosis is associated with a lower likelihood of distant stage in screen amenable cancers but does not fully ameliorate disparities. IMPACT: Our study highlights the importance of health insurance coverage prior to diagnosis and demonstrates that while targeted programs such as the NBCCEDP provide critical access to screening, they are not a substitute for comprehensive insurance coverage.

The National Cancer Institute (NCI) Surveillance, Epidemiology, and End Results (SEER) program is continuously exploring opportunities to augment its already extensive collection of data, enhance the quality of reported cancer information, and contribute to more comprehensive analyses of cancer burden. This manuscript describes a recent linkage of the LexisNexis longitudinal residential history data with 11 SEER registries and provides estimates of the inter-state mobility of SEER cancer patients. To identify mobility from one state to another, we used state postal abbreviations to generate state-level residential histories. From this, we determined how often cancer patients moved from state-to-state. The results in this paper provide information on the linkage with LexisNexis data and useful information on state-to-state residential mobility patterns of a large portion of US cancer patients for the most recent 1-, 2-, 3-, 4-, and 5-year periods. We show that mobility patterns vary by geographic area, race/ethnicity and age, and cancer patients tend to move less than the general population.

BACKGROUND: Little is known about the real-world care of young adult (YA) females (aged 20-39 years) with breast cancer. This study describes factors associated with the receipt of guideline-concordant care (GCC) among YAs. METHODS: The authors identified 1259 YA women with invasive breast cancer diagnosed in 2013 in the National Cancer Institute's Patterns of Care study. Hospital records were re-abstracted, and treatment was verified. Using the National Comprehensive Cancer Network's 2013 breast cancer guidelines, the authors assessed the receipt of GCC by cancer subtype among a subset of YAs (n = 952). Associations between sociodemographic and clinical factors and GCC receipt were examined. RESULTS: Most YAs were 35 to 39 years old (51.2%) and partnered (56.4%); half had hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) tumors. GCC was found for 81.7% of YAs. Relationships between sociodemographic and clinical factors and GCC receipt differed by subtype. Stage was the only significant predictor of GCC receipt for all subtypes (stage II vs III: odds ratio [OR] for HR+/HER2+, 0.20; 95% confidence interval [CI], 0.08-0.50; OR for HR-/HER2+, 0.13; 95% CI, 0.07-0.25; OR for HR-/HER2-, 3.86; 95% CI, 1.55-9.62; OR for HR+/HER2-, 2.81; 95% CI, 1.63-5.80). CONCLUSIONS: GCC is high among YAs with breast cancer. The effects of sociodemographic factors and treatment facility size on GCC differ by subtype. Consistent with recommendations, tumor biology, not age, is associated with GCC for all subtypes. Future studies should assess the effect of GCC on survival among YAs.

BACKGROUND: A national data source for identifying patients with cancer enrolled in Medicaid is needed to evaluate cancer care for low-income, publicly insured patients. In this study, a population-based data set of patients diagnosed with cancer and enrolled in Medicaid was created and evaluated. The objective was to compare the characteristics of patients with cancer identified in Surveillance, Epidemiology, and End Results (SEER) data and linked to the Medicaid Analytic eXtract (MAX) Personal Summary files with the characteristics of patients who were not linked to the MAX file. METHODS: All persons in 14 SEER registries diagnosed with cancer from 2006 to 2013 who were or were not linked to the 2006-2013 nationwide MAX files were selected, and patient demographic characteristics were compared for 3 age groups. Common cancer sites and the timing of Medicaid enrollment with respect to patients' cancer diagnoses were reported, and the stage at diagnosis and 4-year mortality were compared by 3 categories of Medicaid enrollment. RESULTS: Approximately 18% of the sample was enrolled in Medicaid within 25 months of diagnosis. Enrollees had a greater proportion of racial/ethnic minorities in comparison with patients who were not enrolled. A late-stage diagnosis was more common among Medicaid patients and particularly among those who enrolled after their diagnosis. For every common cancer site, mortality was highest in the sample of Medicaid patients who enrolled after their diagnosis. CONCLUSIONS: The Medicaid enrollment data newly added to SEER records enhance researchers' ability to investigate research questions related to Medicaid policies and care delivery. For patients enrolled before their diagnosis, Medicaid appears to offer protection against late-stage disease and mortality.

RESUMO
BACKGROUND: Black women with ovarian cancer experience worse survival than white women. Receipt of guideline care improves survival, yet care may vary by race. We assessed rates of guideline care and role of guideline treatment on survival disparities. METHODS: This retrospective cohort analysis used the NCI's Patterns of Care data for women diagnosed with ovarian cancer, 2002 and 2011 (weighted n = 3,999), with follow-up through December 12, 2014. Logistic regression included patient characteristics, insurance, and gynecologic oncologist (GO) consultation to produce adjusted standardized percentages of women receiving guideline treatment by race. Cox proportional hazards analysis assessed risk of ovarian cancer death. RESULTS: Guideline care was significantly lower for black women compared with white women (adjusted 27.5% vs. 34.1%). Increased receipt of guideline care was associated with GO consultation, younger ages, stage, and insurance. Rates of GO consultation were comparable for black and white women, approximately 60%. Black women were more likely to receive no surgery or no chemotherapy if they did not consult a GO. The unadjusted death risk was significantly higher in black women (HR = 1.33). After adjusting for receipt of guideline care and other factors, black and white women had similar risk of death (HR = 1.05). CONCLUSIONS: Race was not associated with risk of death when guideline care was included in multivariate survival models. However, black patients received less guideline care. GO consultation significantly increased receipt of guideline care. IMPACT: Research is needed to understand treatment perspectives for black patients and their providers to increase the receipt of guideline care and reduce survival disparities.

INTRODUCTION: Non-Hispanic black (NHB) women with breast cancer have poorer survival than non-Hispanic white (NHW) women. Although NHB women are more often diagnosed at later stages, it is less established whether racial disparities exist among women diagnosed with late-stage breast cancer, particularly when care is provided in the community setting. METHODS: Treatment and survival were examined by race/ethnicity among women diagnosed in 2012 with stage IIIB-IV breast cancer using the National Cancer Institute's population-based Patterns of Care Study. Medical records were re-abstracted and treating physicians were contacted to verify therapy. Vital status was available through 2014. RESULTS: A total of 533 women with stage IIIB-C and 625 with stage IV tumors were included; NHW women comprised about 70% of each group. Among women with stage IIIB-C disease, racial/ethnicity variations in systemic treatment were not observed but there was a borderline association indicating worse all-cause mortality among NHB women (hazard ratio 1.52; 95% confidence interval (CI) 0.96-2.41). In contrast, among women with stage IV disease, borderline associations indicating NHB women were more likely to receive chemotherapy (OR 1.44, 95% CI 0.90-2.30) and, among those with hormone receptor-positive tumors, less likely to receive endocrine therapy (OR 0.60, 95% CI 0.35-1.04). All-cause mortality did not vary by race/ethnicity for stage IV disease (hazard ratio 0.92; 95% CI 0.68-1.25). CONCLUSIONS: More research is needed to identify additional factors associated with the potential survival disparities among women with stage IIIB-C disease and potential treatment disparities among women with stage IV disease.

BACKGROUND: The adoption of sorafenib into oncology practice as a first-line systemic treatment for advanced hepatocellular carcinoma (HCC) is not well understood. We examined sorafenib use since Food and Drug Administration (FDA) approval in 2007 and associated survival for individuals diagnosed with advanced HCC, conducting a population-based evaluation of treatment patterns and outcomes for this newly approved drug in the US over time. METHODS: We identified individuals diagnosed with Barcelona Clinic Liver Cancer Stage C from the 2007 and 2012 National Cancer Institute Patterns of Care study. We examined trends in use as well as patient and clinical factors associated with receiving sorafenib using multivariate logistic regression analysis. We then evaluated the association between sorafenib use and overall hazard of death using multivariate Cox proportional hazards regression. RESULTS: Among 550 individuals diagnosed with advanced HCC, we found no significant increase in the proportion of patients treated with sorafenib from 2007 to 2012 (26.3 vs. 30.4%). After adjusting for patient and clinical characteristics, non-Hispanic Blacks (compared to non-Hispanic Whites) and those with a lower Child-Pugh score remained more likely to receive sorafenib. Individuals receiving systemic chemotherapy only, radiation therapy only, or no treatment at all experienced a higher risk of death than those treated with sorafenib, while those receiving a transplant experienced a lower risk of death. CONCLUSIONS: Sorafenib has not been widely adopted into oncology practice since FDA approval for advanced HCC. Few factors apart from Child-Pugh score and race/ethnicity predict sorafenib use in clinical practice, although sorafenib treatment is associated with a lower risk of death.
RESUMO
BACKGROUND: Childhood neuroblastoma describes a heterogeneous group of extracranial solid tumors, that are treated per risk profile. We sought to describe treatment patterns and survival using population-based data from throughout the United States. MATERIALS AND METHODS: Using the National Cancer Institute (NCI)'s Patterns of Care data, we analyzed treatment provided to newly diagnosed, histologically confirmed neuroblastoma patients in 2010 and 2011, registered to one of 14 Surveillance, Epidemiology, and End Results (SEER) cancer registries. Data were re-abstracted from hospital records and treating physicians contacted for verification. Application of the Children's Oncology Group (COG)'s 3-level (low, intermediate and high) neuroblastoma risk classification system for therapeutic decision-making provided insight to community-based treatment patterns. Kaplan-Meier survival analyses, based on 5-years of follow-up, were also performed. RESULTS: 76% of the 250 patients were enrolled on an open/active clinical trial. All low-risk patients received surgery. Most intermediate-risk patients (81%) received a chemotherapy regimen that included carboplatin, etoposide, cyclophosphamide and doxorubicin. High-risk patients received extensive, multimodal treatment consisting of chemotherapy, surgery, myeloablative chemotherapy with stem cell rescue (transplant), radiation, immunotherapy (dinutuximab), and isotretinoin therapy. 21% patients had died at the end of the maximum 60-month follow-up period. The 5-year estimated survival rates were lower for patients diagnosed with stage 4 disease, unfavorable DNA ploidy, MYCN gene amplification or classified as high-risk. CONCLUSION: Most neuroblastoma patients are registered on a risk-based open/active clinical trial. Variation in modality, systemic agents and sequence of treatment reflects the heterogeneity of therapy received by these patients.

OBJECTIVE: Patients with a history of suicidal ideation or attempts, especially if they have serious psychopathology with repeated hospitalizations, are burdened by ongoing risk for suicide. We studied this high-risk group to assess their psychological status following their most recent suicide attempt, in contrast to equally ill patients without a suicide history. Further, among suicidal patients, we compared those with only ideation, with a non-medically serious suicide attempt and with medically serious suicide attempts. We also report on the development of a new measure of psychic pain. METHODS: Patients in residential treatment (n=131) completed self-report questionnaires about suicide history, impulsiveness, psychic pain, resilience, and reasons for living. A series of univariate ordinal logistic regressions identified variables to include in a multivariable logistic regression to examine the odds associated with increasing levels of suicidality. RESULTS: A history of suicidal ideation or suicide attempts is associated with proportionally more psychic pain and fewer current reasons for living. Prior history of abuse, impulsiveness, and general resilience were not significantly associated with suicidal severity. CONCLUSIONS: For patients who have suicidal ideation, or have attempted suicide, and also have additional risk factors including past hospitalization, treatments should include both understanding the sources of psychic pain and promoting individual discovery of reasons for living.

BACKGROUND: Researchers have used prostate-specific antigen (PSA) values collected by central cancer registries to evaluate tumors for potential aggressive clinical disease. An independent study collecting PSA values suggested a high error rate (18%) related to implied decimal points. To evaluate the error rate in the Surveillance, Epidemiology, and End Results (SEER) program, a comprehensive review of PSA values recorded across all SEER registries was performed. METHODS: Consolidated PSA values for eligible prostate cancer cases in SEER registries were reviewed and compared with text documentation from abstracted records. Four types of classification errors were identified: implied decimal point errors, abstraction or coding implementation errors, nonsignificant errors, and changes related to "unknown" values. RESULTS: A total of 50,277 prostate cancer cases diagnosed in 2012 were reviewed. Approximately 94.15% of cases did not have meaningful changes (85.85% correct, 5.58% with a nonsignificant change of <1 ng/mL, and 2.80% with no clinical change). Approximately 5.70% of cases had meaningful changes (1.93% due to implied decimal point errors, 1.54% due to abstract or coding errors, and 2.23% due to errors related to unknown categories). Only 419 of the original 50,277 cases (0.83%) resulted in a change in disease stage due to a corrected PSA value. CONCLUSIONS: The implied decimal error rate was only 1.93% of all cases in the current validation study, with a meaningful error rate of 5.81%. The reasons for the lower error rate in SEER are likely due to ongoing and rigorous quality control and visual editing processes by the central registries. The SEER program currently is reviewing and correcting PSA values back to 2004 and will re-release these data in the public use research file. Cancer 2017;123:697-703. © 2016 American Cancer Society.

INTRODUCTION: Lung cancer remains a common and deadly cancer in the United States. This study evaluated factors associated with stage-specific cancer therapy and survival focusing on temporal trends and sociodemographic disparities. METHODS: A random sample (n=3,318) of non-small cell lung cancer (NSCLC) patients diagnosed in 1996, 2005 and 2010, and reported to the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) program was analyzed. Logistic regression was utilized to identify factors associated with receipt of surgery among stage I/II patients and chemotherapy among stage IIIB/IV patients. Cox proportional hazard regression was utilized to assess factors associated with all-cause mortality, stratified by stage. RESULTS: Surgery among stage I/II patients decreased non-significantly overtime (1996: 78.8%; 2010: 68.5%; p=0.18), whereas receipt of chemotherapy among stage IIIB/IV patients increased significantly overtime (1996: 36.1%; 2010: 51.2%; p<0.01). Receipt of surgery (70-79 and ≥80 vs. <70: Odds Ratio(OR):0.31; 95% Confidence Interval (CI): 0.16-0.63 and OR:0.04; 95% CI: 0.02-0.10, respectively) and chemotherapy (≥80 vs. <70: OR: 0.26; 95% CI:0.15-0.45) was less likely among older patients. Median survival improved non-significantly among stage I/II patients from 51 to 64 months (p=0.75) and significantly among IIIB/IV patients from 4 to 5 months (p<0.01). CONCLUSION: Treatment disparities were observed in both stage groups, notably among older patients. Among stage I/II patients, survival did not change significantly possibly due to stable surgery utilization. Among stage IIIB/IV patients, although the use of chemotherapy increased and survival improved, the one-month increase in median survival highlights the need for addition research.

OBJECTIVE: This study's objective was determine the incremental association of reasons for living to the lifetime number of suicide attempts in relation to other known risk and protective factors in a sample of psychiatric patients with extensive psychopathology in residential treatment. METHODS: Participants (n = 131) completed a demographic questionnaire that also asked for information about lifetime suicide history, psychiatric history, trauma, and abuse history. Additional measures of resilience, reasons for living (RFL), and impulsiveness were completed. RESULTS: A history of sexual abuse was associated with an increasing lifetime number of suicide attempts, while a history of physical abuse and trait impulsiveness were not associated with the lifetime number of suicide attempts. Survival and coping beliefs, a subscale of the Reasons for Living Inventory (RFLI), was found to add incremental predictive validity to the number of lifetime suicide attempts. A composite fear variable, combining fear of suicide and fear of social consequences of suicide, was negatively correlated with lifetime number of attempts but did not add incremental validity to the prediction of lifetime number of suicide attempts. CONCLUSION: In a sample of participants with significant psychiatric impairment, the protective factor of survival and coping beliefs may be an important barrier to repeated suicide attempts and may be considered a suicide-specific resilience measure. Understanding the psychological processes contributing to the development of such protective factors as resilience, meaning in life, and coping resources is an important area of study and a potential avenue for targeted therapeutic intervention in high-risk populations.

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) incidence is expected to rise dramatically over the next decades because of increasing hepatitis C infections and obesity-related comorbidities. However, little information exists regarding the treatment of patients with HCC in the community setting. The purpose of this article was to characterize patterns of diagnosis, treatment, and survival for HCC in the community. METHODS: We identified 946 HCC patients in the 2007 National Cancer Institute's Patterns of Care study. Chi-square analyses and multivariable regression were used to examine patient and provider factors associated with treatment and survival by stage at diagnosis. RESULTS: Our primary findings indicate that liver transplants, embolization, or radiofrequency ablation for Barcelona Clinic Liver Cancer stage A patients were performed significantly less often for non-Hispanic blacks, Hispanics, patients in the highest income quartile, and patients with Medicaid. Patients with stage D disease were less likely to receive cancer therapy if they had Medicaid insurance compared to private insurance (p<0.001 for all). In multivariable analyses, all-cause mortality was associated with treatment in a hospital without a residency training program (hazard ratio [HR] 1.4 [1.1,1.9]), more advanced stage (HR: 10.6 [5.7, 19.5] stage D vs. A), and lack of appropriate treatment (HR: 2.4 [1.9,3.2]). CONCLUSIONS: This is the first population-based study to evaluate therapy provided for HCC in the community. Current therapy depended on patients' HCC stage at diagnosis and other clinical and demographic factors. Overall, our study identifies those least likely to receive specific therapies in a variety of health care settings and can inform strategies for promoting appropriate therapy now and as new agents are developed.
RESUMO
OBJECTIVES: The National Cancer Institute (NCI) annually confirms therapy with treating physicians on a sample of patients diagnosed with a specific cancer. METHODS: Using the NCI Patterns of Care data, treatment patterns were examined on a population-based sample of patients diagnosed with gastrointestinal stromal tumors (GIST) in 2008. RESULTS: A random sample of 323 of 405 GIST patients registered in SEER was selected. Most patients had gastric GISTs, were ≥ 65 years, white, had private insurance, and treated in a hospital with a residency program. Surgery was primarily performed in patients with non-metastatic disease (94%), in which: 26, 12, and 36% were at low, intermediate, and high-risk of recurrence, respectively. Amongst low-risk patients, â¼ 30% received adjuvant therapy. Amongst patients at higher risk, 26-40% did not receive adjuvant therapy. Imatinib was the most common targeted therapy administered. On multivariate analysis, age and risk-group were associated with receipt of adjuvant targeted therapy. CONCLUSIONS: Our study shows that in 2008, the majority of patients diagnosed with GIST received appropriate surgical and adjuvant therapies. However, a considerable subset may have been overtreated and undertreated. Future studies identifying factors that impact the delivery of adjuvant therapy should be conducted.

INTRODUCTION: Thyroid cancer incidence is rising in the United States. Although overall thyroid cancer survival is high, prognostic stratification schemes have been developed to better delineate patients with poor prognoses. METHODS: A random sample that included 1,003 adult papillary thyroid cancer patients diagnosed in 2006 and reported to the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) program had their medical records re-abstracted and additional risk factor data collected. The distribution of patient demographics, medical histories, tumor characteristics and treatment modalities were assessed. Logistic regression was used to assess factors associated with total thyroidectomy (total, subtotal or near total) and radioiodine therapy. All analyses were conducted stratified by the Age, Metastases, Extent and Size (AMES) low/high-risk classification. RESULTS: Receipt of total thyroidectomy was associated with family history of thyroid disease/cancer and larger tumor size among low-risk patients and smaller tumor size among high-risk patients. Among low-risk patients, the receipt of radioiodine was associated with family history of thyroid disease/cancer, larger tumor size, total thyroidectomy, and positive lymph nodes. Among high-risk patients, the receipt of radioiodine was associated with intermediate tumor and hospital sizes. CONCLUSIONS: This study provides insight into the patterns of papillary thyroid cancer care in the general population. The findings from this study indicate adherence to guideline recommendations in that family history of thyroid disease/cancer, in addition to tumor characteristics, does appear to inform treatment practices, especially among low-risk patients.
