BACKGROUND Smoking, the most common risk factor for bladder cancer (BC), is associated with increased complications after radical cystectomy (RC), poorer oncologic outcomes, and higher mortality. The authors hypothesized that the effect of smoking on the probability of major complications increases with increasing age among patients who undergo RC. METHODS The authors analyzed the American College of Surgeons National Surgical Quality Improvement Program database (2011-2017), identified all patients undergoing RC using Current Procedural Terminology codes, and formed two groups according to smoking status (active smoker and nonsmoker [included former and never-smokers]). Patient characteristics and 30-day postoperative complications using the Clavien-Dindo Classification (CDC) were assessed. A multivariable logistic regression model was constructed that included age, sex, race, body mass index, operative time, comorbidities, chemotherapy status, and type of diversion with major complications (CDC ≥III) as the outcome variable, and explored the interaction between age and smoking status. RESULTS A total of 10,528 patients underwent RC, including 22.8% who were active smokers. The authors identified an interaction between age and smoking status (P = .045). Older patients were found to experience a stronger smoking effect than younger patients with regard to the probability of major complications. The risk of a major complication was the same for 50-year-old nonsmokers and smokers, but it increased from 17.8% to 21.7% for 70-year-old nonsmokers and smokers, respectively (P < .001). CONCLUSIONS Up to 20% of patients who undergo RC are active smokers, and these individuals have an increased risk of major complications. The effect of smoking is stronger with increasing age; the difference with regard to complications for smokers versus nonsmokers was found to increase substantially, wherein older smokers are at an especially high risk of complications.

Background Breast cancer 2 (BRCA2)-associated breast and ovarian cancers are sensitive to platinum-based chemotherapy. It is unknown whether BRCA2-associated prostate cancer responds favorably to such treatment. Methods A retrospective analysis of a single-institution cohort of men with castration-resistant, metastatic prostate cancer was performed to determine the association between carrier status of pathogenic BRCA2 germline variants and prostate-specific antigen response to carboplatin-based chemotherapy. From 2001 through 2015, 8081 adult men with prostate cancer who had a consultation and/or underwent treatment at Dana-Farber Cancer Institute provided blood samples and consented to analyses of biologic material and clinical records. A subgroup of 141 men received at least 2 doses of carboplatin and docetaxel for castration-resistant disease (94% were also taxane refractory). These patients were categorized according to the absence or presence of pathogenic germline mutations in BRCA2 based on DNA sequencing from whole blood. The primary outcome was the response rate to carboplatin/docetaxel chemotherapy, defined according to a decline in prostate-specific antigen that exceeded 50% within 12 weeks of initiating this regimen. Associations between BRCA2 mutation status and response to carboplatin-based chemotherapy were tested using the Fisher exact test, with a 2-sided P value Results Pathogenic germline BRCA2 variants were observed in 8 of 141 men (5.7%; 95% confidence interval, 2.5%-10.9%). Six of 8 BRCA2 carriers (75%) experienced prostate-specific antigen declines >50% within 12 weeks, compared with 23 of 133 noncarriers (17%; absolute difference, 58%; 95% confidence interval, 27%-88%; P Conclusions BRCA2-associated, castration-resistant prostate cancer is associated with a higher likelihood of response to carboplatin-based chemotherapy than non-BRCA2-associated prostate cancer.

BACKGROUND Racial/ethnic and socioeconomic disparities persist in part because our current understanding of the care provided to minority and disadvantaged populations is limited. The authors evaluated the quality of breast cancer care in 2 large states to understand the disparities experienced by African Americans, Hispanics, Asian/Pacific Islanders (APIs), and Medicaid enrollees and to prioritize remediation strategies. METHODS Statewide cancer registry data for 80,436 women in New York and 121,233 women in California who were diagnosed during 2004 to 2009 with stage 0 through III breast cancer were used to assess underuse and overuse of surgery, radiation, chemotherapy, and hormone therapy based on 34 quality measures. Concordance values were compared across racial/ethnic and Medicaid-enrollment groups. Multivariable models were used to quantify disparities across groups for each treatment in each state. RESULTS Overall concordance was 76% for underuse measures and 87% for overuse measures. The proportions of patients who received care concordant with all relevant measures were 35% in New York and 33% in California. Compared with whites, African Americans were less likely to receive recommended surgery, radiation, and hormone therapy; Hispanics and APIs were usually more likely to receive recommended chemotherapy. Across states, the same racial/ethnic groups did not always experience the same disparities. Medicaid enrollment was associated with decreased likelihood of receiving all recommended treatments, except chemotherapy, in both states. Overuse was evident for hormone therapy and axillary surgery but was not associated with race/ethnicity or Medicaid enrollment. CONCLUSIONS Patient-level measures of quality identify substantial problems with care quality and meaningful disparities. Remediating these problems will require prioritizing low-performing measures and targeting high-risk populations, possibly in different ways for different regions.

BACKGROUND Pancreatic cancer is a major cause of morbidity and mortality in the Medicare population. Whether the health care burden of pancreatic cancer has changed over the last decade is unknown. METHODS The authors used Medicare data from 2000 to 2010 to identify beneficiaries aged ≥ 65 years who were hospitalized for the management of pancreatic cancer. Annual trends were estimated for the age-sex-race–adjusted initial hospitalization rate, the age-sex-race-comorbidity–adjusted 1-year mortality rate after initial hospitalization, age-sex-race-comorbidity–adjusted procedure rates, 1-year all-cause rehospitalizations after initial pancreatic cancer hospitalization, and mean inflation-adjusted Medicare payment for initial hospitalization. RESULTS A total of 130,728 patients had ≥ 1 hospitalizations for pancreatic cancer and were identified from 56,642,071 beneficiaries during the study period. The age-sex-race–adjusted rate of initial hospitalization for pancreatic cancer was 50 per 100,000 person-years in 2010, representing a 0.5% annual increase since 2000 (95% confidence interval [95% CI], 0.3%-0.7%). In the same period, the age-sex-race-comorbidity–adjusted 1-year mortality rate decreased by 4.4% (95% CI, 3.9%-4.9%), and the age-sex-race-comorbidity–adjusted surgical resection rate increased by 6.9% (95% CI, 6.4%-7.5%). The mean inflation-adjusted Medicare payment for the initial hospitalization decreased, from $14,118 in 2000 to $13,318 in 2010, and the number of 1-year all-cause rehospitalizations after the initial hospitalization increased from 0.75 per patient in 2000 to 0.82 per patient in 2009 (all P

BACKGROUND Rates of screening mammography have plateaued, and the number of mammography facilities has declined in the past decade. The objective of this study was to assess changes over time and geographic disparities in the availability of mammography services. METHODS Using information from the US Food and Drug Administration and the US Census, county-level mammography capacity was defined as the number of mammography machines per 10,000 women aged ≥ 40 years. Cross-sectional variation and longitudinal changes in capacity were examined in relation to county characteristics. RESULTS Between 2000 and 2010, the number of mammography facilities declined 10% from 9434 to 8469, the number of mammography machines declined 10% from 13,100 to 11,762, and the median county mammography capacity decreased nearly 20% from 1.77 to 1.42 machines per 10,000 women aged ≥ 40 years. In cross-sectional analysis, counties with greater percentages of uninsured residents, less educated residents, greater population density, and higher managed care penetration had lower mammography capacity. Conversely, counties with more hospital beds per 100,000 population had higher capacity. High initial mammography capacity, growth in both the percentage of the population aged ≥ 65 years and the percentage living in poverty, and increased managed care penetration were all associated with a decrease in mammography capacity between 2000 and 2010. Only the percentage of rural residents was associated with an increase in capacity. CONCLUSIONS Geographic variation in mammography capacity and declines in capacity over time are associated with demographic, socioeconomic, and health care market characteristics. Maldistribution of mammography resources may explain geographic disparities in breast cancer screening rates. Cancer 2013;119:3847–3853. © 2013 American Cancer Society.

BACKGROUND Randomized trials report equivalent efficacy among various combinations of platinum-based regimens in advanced non–small cell lung cancer (NSCLC). Their relative effectiveness and comparability based on squamous versus nonsquamous histology is uncertain. METHODS The authors used the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data to identify first-line chemotherapy agents administered to Medicare beneficiaries with stage IIIB or IV NSCLC diagnosed from 2000 to 2007. Overall survival was compared between patients who received the 3 most common regimens: carboplatin-paclitaxel, carboplatin-gemcitabine, and carboplatin-docetaxel. Stratified analyses distinguished between the outcomes of patients with squamous versus nonsquamous cell histology. Multivariable Cox proportional hazards models and propensity score analyses facilitated adjustment for imbalance in measurable patient characteristics. RESULTS Of the 15,318 patients who received first-line chemotherapy, 43.1% received carboplatin-paclitaxel, 14.3% received carboplatin-gemcitabine, 8.5% received carboplatin-docetaxel, and 34.1% received other regimens. The median survival was 8.0 months (interquartile range [IQR], 3.5-17.4 months) for carboplatin-paclitaxel, 7.3 months (IQR, 3.4-15.2 months) for carboplatin-gemcitabine, and 7.5 months (IQR, 3.2-16.0 months) for carboplatin-docetaxel. Both multivariable and propensity score-adjusted Cox models demonstrated a slight inferiority associated with carboplatin-gemcitabine or carboplatin-docetaxel versus carboplatin-paclitaxel, with a hazard ratio of 1.10 (95% confidence interval, 1.04-1.15) and 1.09 (95% confidence interval, 1.02-1.16), respectively, in propensity score-stratified models. Among the subgroup of 2063 patients with squamous carcinoma, propensity score-stratified analyses had a higher risk of death (hazard ratio, 1.20; 95% confidence interval, 1.07-1.35) associated with carboplatin-gemcitabine versus carboplatin-paclitaxel. CONCLUSIONS Carboplatin-paclitaxel was associated with slightly better survival compared with carboplatin-gemcitabine or carboplatin-docetaxel within the Medicare population with advanced NSCLC, and this was most pronounced for patients who had squamous cell histology.

BACKGROUND: In clinical trials, combined 5-fluorouracil (5FU) plus oxaliplatin improves the survival of patients who have resected, stage III colon cancer with manageable toxicity. However, the tolerability of this in the general population of patients with colon cancer is uncertain. METHODS: Adverse outcomes were compared in patients with stage III colon cancer who received either 5FU or 5FU/oxaliplatin within 120 days of undergoing resection versus a control group of patients with stage II colon cancer who did not receive chemotherapy in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database and in data from the New York State Cancer Registry linked to Medicare and Medicaid. Hospitalizations, emergency room (ER) visits, and outpatient adverse events (AEs) were measured in claims from 30 days to 9 months after patients underwent resection. Multiple logistic regression was used to calculate adjusted odds ratios of events by treatment. Propensity score matching was used to minimize selection bias. RESULTS: Adverse outcomes were more frequent for chemotherapy recipients. AE rates were higher in patients who received 5FU/oxaliplatin (81%) compared with patients who received 5FU alone (72%), in the SEER-Medicare data. The effect of oxaliplatin on AEs was greater in older patients: The odds ratio was 2.10 (95% confidence interval, 1.53-2.87) for patients aged ≥75 years versus 1.75 (95% confidence interval, 1.39-2.21) for patients aged

BACKGROUND. Preoperative chemoradiation is the standard treatment for locally advanced rectal cancer. However, it is uncertain whether pretreatment clinical stage, degree of response to neoadjuvant treatment, or pathologic stage is the most reliable predictor of outcome. This study compared various staging elements and treatment-related variables to identify which factors or combination of factors reliably prognosticates disease-free survival in rectal cancer patients receiving neoadjuvant combined modality therapy. METHODS. From a prospectively maintained single institution database, 342 consecutive patients with locally advanced rectal cancer staged by endorectal ultrasound were identified. Patients underwent rectal resection 4 to 8 weeks after a 5.5-week course of pelvic radiotherapy/concurrent chemotherapy. The degree of tumor regression was histologically graded on each resected specimen using a previously reported response scale of 0% to 100%. Predictive models of disease-free survival were created utilizing available pretherapy and postoperative staging elements in addition to the degree of tumor regression noted histologically. Model accuracy was measured and compared by concordance index, with 95% confidence interval (CI). RESULTS. Stratifying patients by degree of tumor regression predicted outcome with a concordance index of 0.65 (95% CI, 0.59–0.71), which was significantly better than models using preoperative stage elements (concordance index of 0.54; 95% CI, 0.50–0.58). However, the model found to be most predictive of disease-free survival stratified patients by final pathologic T classification and N classification elements, with a concordance index of 0.75 (95% CI, 0.70–0.80). CONCLUSIONS. Tumor response to preoperative therapy is a strong predictor of disease-free survival. However, outcome is most accurately estimated by final pathologic stage, which is influenced by both preoperative stage and response to therapy. Cancer 2008. © 2008 American Cancer Society.

BACKGROUND. Although patients who have early-stage oropharyngeal cancer can be treated with little impairment of function, the treatment of advanced disease can result in decreased quality of life and mortality. Patients without insurance and with other barriers to access to care may delay seeking medical attention for early symptoms, resulting in more advanced disease at presentation. In this study, the authors examined whether patients who had no insurance or who were covered by Medicaid insurance were more likely to present with advanced oropharyngeal cancer. METHODS. In this retrospective cohort study from the National Cancer Database from 1996 to 2003, patients with known insurance status who were diagnosed with invasive oropharyngeal cancer at Commission on Cancer facilities (n 5 40,487) were included. Adjusted and unadjusted logistic regression models were used to analyze the likelihood of presenting with more advanced stage disease. RESULTS. After controlling for other sociodemographic characteristics, patients with advanced oropharyngeal cancer at diagnosis were more likely to be uninsured (odds ratio [OR], 1.37; 95% confidence interval [95% CI], 1.21–1.25) or covered by Medicaid (OR, 1.31; 95% CI, 1.19–1.46) compared with patients who had private insurance. Similarly, patients were most likely to present with the largest tumors (T4 disease) if they were uninsured (OR, 2.82; 95% CI, 2.46–3.23) or covered by Medicaid (OR, 2.95; 95% CI, 2.63–3.31). They also were more likely to present with the greatest degree of lymph node involvement (N3) if they were uninsured (OR, 2.06; 95% CI, 1.76–2.40) or covered by Medicaid (OR, 1.66; 95% CI, 1.45–1.90). CONCLUSIONS. Individuals who lacked insurance or had Medicaid coverage were at the greatest risk for presenting with advanced oropharyngeal cancer. In the current study, the results for the Medicaid group may have been influenced by the postdiagnostic enrollment of uninsured patients. Insurance coverage appeared to be a highly modifiable predictor of cancer stage. The findings indicated that it is important to consider the impact of insurance coverage on disease stage at diagnosis and associated morbidity, mortality, and quality of life.

BACKGROUND Individuals without medical insurance or with limited insurance are less likely than those with broader insurance coverage to receive preventive services and to seek timely medical care. The authors examined the associations of insurance status with stage at diagnosis among women with breast cancer. METHODS This study included women age ≥40 years who were diagnosed with invasive breast cancer from 1998 to 2003 and who were reported to the National Cancer Data Base. Multivariable logistic regression analyses were used to examine the associations of insurance status with more advanced-stage breast cancer at diagnosis while controlling for other patient characteristics. RESULTS Among the 533,715 women with breast cancer who were included in the current analysis, the proportions with advanced-stage (III/IV) cancer at diagnosis ranged from 8% among privately insured patients to 18% among uninsured patients and 19% among Medicaid patients; differences in the proportions of women with advanced-stage cancer were statistically significant (P < .0001). Regression analyses indicated that, compared with privately insured patients, uninsured patients and Medicaid patients had a greater likelihood of diagnosis at stage II (odds ratio [OR], ∼≈1.5) or at stages III/IV (OR, 2.4) versus stage I (P < .001). Black and Hispanic patients also were significantly more likely than white patients to be diagnosed at a more advanced stage (P < .001). CONCLUSIONS The results from this study provided strong evidence that patients without health insurance or with Medicaid coverage, as well as black and Hispanic patients, were more likely to present with advanced-stage breast cancer. These results are consistent with other reports that have documented less use of preventive services, including mammography, among uninsured women and delays in diagnosis and treatment for black and Hispanic women.

Racial/ethnic and socioeconomic disparities persist in part because our current understanding of the care provided to minority and disadvantaged populations is limited. The authors evaluated the quality of breast cancer care in 2 large states to understand the disparities experienced by African Americans, Hispanics, Asian/Pacific Islanders (APIs), and Medicaid enrollees and to prioritize remediation strategies.Statewide cancer registry data for 80,436 women in New York and 121,233 women in California who were diagnosed during 2004 to 2009 with stage 0 through III breast cancer were used to assess underuse and overuse of surgery, radiation, chemotherapy, and hormone therapy based on 34 quality measures. Concordance values were compared across racial/ethnic and Medicaid-enrollment groups. Multivariable models were used to quantify disparities across groups for each treatment in each state.Overall concordance was 76% for underuse measures and 87% for overuse measures. The proportions of patients who received care concordant with all relevant measures were 35% in New York and 33% in California. Compared with whites, African Americans were less likely to receive recommended surgery, radiation, and hormone therapy; Hispanics and APIs were usually more likely to receive recommended chemotherapy. Across states, the same racial/ethnic groups did not always experience the same disparities. Medicaid enrollment was associated with decreased likelihood of receiving all recommended treatments, except chemotherapy, in both states. Overuse was evident for hormone therapy and axillary surgery but was not associated with race/ethnicity or Medicaid enrollment.Patient-level measures of quality identify substantial problems with care quality and meaningful disparities. Remediating these problems will require prioritizing low-performing measures and targeting high-risk populations, possibly in different ways for different regions.

BACKGROUND. Although colorectal cancer (CRC) is the second leading cause of cancer death in the U.S., available interventions to reduce CRC mortality are disseminated only partially throughout the population. This study assessed the potential reduction in CRC mortality that may be achieved through further dissemination of current interventions for risk-factor modification, screening, and treatment. METHODS. The MISCAN-COLON microsimulation model was used to simulate the 2000 U.S. population with respect to CRC risk-factor prevalence, screening use, and treatment use. The model was used to project age-standardized CRC mortality from 2000 to 2020 for 3 intervention scenarios. RESULTS. Without changes in risk-factor prevalence, screening use, and treatment use after 2000, CRC mortality would decrease by 17% by the Year 2020. If the 1995 to 2000 trends continue, then the projected reduction in mortality would be 36%. However, if trends in the prevalence of risk-factors could be improved above continued trends, if screening use increased to 70% of the target population, and if the use of chemotherapy increased among all age groups, then a 49% reduction would be possible. Screening drove most (23%) of the projected mortality reduction with these optimistic trends; however, decreasing risk-factors (16%) and increasing use of chemotherapy (10%) also contributed substantially. The contribution of risk-factors may have been overestimated, because effect estimates could not be obtained from randomized controlled trials. CONCLUSIONS. Currently available interventions for risk-factor modification, screening, and treatment have the potential to reduce CRC mortality by almost 50% by the Year 2020. However, without action now to further increase the uptake of current effective interventions, the reduction in CRC mortality may be only 17%. Cancer 2006. © American Cancer Society.

BACKGROUND The results of a randomized comparison study (N9741) showed that oxaliplatin and infusional fluorouracil (FU) (FOLFOX) was superior to the previous standard of care in the United States, irinotecan and bolus FU (IFL), as first-line therapy for patients with metastatic colon carcinoma. The trade-offs between costs and survival for these two regimens have not been explored. METHODS A post-hoc, incremental cost-effectiveness (ICE) projection using simulated cohorts of patients starting FOLFOX or IFL was tracked for major clinical events, toxicities, and survival. Recurrence and survival risks were based on clinical trial data. Resource use was projected using observed dose intensity, duration of therapy, delays in therapy, and toxicities Grade > 2 in N9741. The frequency, costs, and consequences of second-line therapy were examined. The time frame was 5 years, and the perspective was that of Medicare as a third-party payer. RESULTS Initial treatment with FOLFOX versus IFL had an average incremental cost of $29,523, a survival benefit of 4.4 months, and an ICE of $80,410 per life year (LY), $111,890 per quality-adjusted LY, and $89,080 per progression-free year. By using the 95% confidence interval for the time to progression observed in N9741, the ICE associated with FOLFOX ranged from $121,220 to $59,250 per LY. In the clinical trial, dose delays and skipped doses were frequent. If progression-free patients were treated without delay for the first year or lifetime, then the ICE for FOLFOX increased to $117,910 and $222,200 per LY, respectively. The ICE increased to $84,780 per LY when the model incorporated a revised IFL schedule with lower early toxicity and similar rates of treatment with second-line regimens. CONCLUSIONS FOLFOX provided substantial benefits that incurred substantial additional costs. The ICE for FOLFOX fell into the upper range of commonly accepted oncology interventions in the context of the United States healthcare system. Cancer 2005. © 2005 American Cancer Society.

BACKGROUND Temporal comparisons of case survival are commonly used to assess improvement in cancer treatment at the population level. However, such comparisons may be confounded by secular trends in disease prognosis, even within conventional stage categories. The objective of the current study was to characterize within-stage migration of tumor size in breast carcinoma, and to estimate the effect of this shift on reported breast carcinoma survival. METHODS Population-based Surveillance, Epidemiology, and End Results (SEER) cancer registry data were used to evaluate secular trends in tumor size at the time of diagnosis and relative survival among localized and regional invasive breast carcinoma patients diagnosed between 1975–1999. Outcomes were stage-specific tumor size distribution, 5-year relative survival, relative survival standardized to the tumor size distribution of the cohort diagnosed between 1975–1979, and the percentage of improvement in relative survival attributable to shifts in tumor size distribution. RESULTS Within each stage category, the proportion of smaller tumors increased significantly over time. Comparing patients diagnosed between 1995–1999 with those diagnosed between 1975–1979, within-stage migration of tumor size accounted for 61% and 28%, respectively, of the relative survival increases noted in localized and regional breast carcinoma. CONCLUSIONS The tumor size distribution of incident breast carcinomas in SEER has shifted toward smaller tumors. A substantial fraction of the improvement in breast carcinoma survival noted since 1975 may be attributable to within-stage migration of tumor size. Cancer 2005. © 2005 American Cancer Society.

BACKGROUND Logistic, cultural, educational, and other barriers can impede the delivery of high-quality cancer care to underserved patients. Patient navigation services represent one innovation for addressing perceived barriers to care encountered by disadvantaged patients. In this report, the authors have 1) defined patient navigation, distinguishing it from other cancer support services; 2) described how programs are organized; and 3) discussed the need for research on program effectiveness. METHODS Information was examined on navigation programs published in the scientific literature and on line. Qualitative research also was conducted, consisting of direct observation of patient care in cancer clinics with and without navigators in northern California, in-person interviews with personnel and patients in the clinics observed, and telephone interviews with navigators at four sites across the United States. RESULTS The authors found that navigation services have been implemented at all stages of cancer care: prevention, screening, treatment, and survival. Navigators differ from other cancer support personnel in their orientation toward flexible problem solving to overcome perceived barriers to care rather than the provision of a predefined set of services. There are no rigorous demonstrations of the effects and effectiveness of navigation, although such studies are underway. CONCLUSIONS Currently, patient navigation is understudied, and literature documenting its effects and effectiveness is scant. Rigorous studies are needed of the navigator role and program costs and benefits. Such studies will facilitate an assessment of program effectiveness, feasibility across a range of health care settings, and performance relative to alternative approaches for addressing barriers to care among the underserved.

BACKGROUND Use of the Internet is common among patients with cancer and their companions. However, little is known about patterns of use of print or telephone-based resources amidst growing Internet utilization, nor is it known whether different types of information are sought from electronic compared with print media. It is not clear as to whether patients and their companions differ in their patterns of content seeking. METHODS A survey was developed to evaluate the use of electronic and nonelectronic informational resources by patients and their companions. During a 10-week period, this questionnaire was administered to 443 outpatients and 124 paired companions attending an urban academic cancer center. RESULTS In this cohort, 64% of patients and 76% of companions were computer owners, with home Internet access indicated by 58% and 68%, respectively. Use of the Internet to obtain cancer-related information was reported by 44% of patients and 60% of companions. Print resources were used by 79% of patients and 83% of companions, with telephone resources used by 22% and 23%, respectively. The majority of Internet users also read print content (85%), whereas one-half of print users did not access data electronically (52%). Topic areas sought via print and the Internet were similar, with the exception of nutrition-related information, which was more commonly sought in print texts. There was a high rate of concordance between patient and companion use of both electronic and nonelectronic resources. CONCLUSIONS Despite recent publicity and scrutiny focusing on the quality of Internet health care content, print products remain the most common source of information sought by patients with cancer. Future investigation should focus on the quality of print products used by patients. Cancer 2004. © 2004 American Cancer Society.

Rates of screening mammography have plateaued, and the number of mammography facilities has declined in the past decade. The objective of this study was to assess changes over time and geographic disparities in the availability of mammography services.Using information from the US Food and Drug Administration and the US Census, county-level mammography capacity was defined as the number of mammography machines per 10,000 women aged ≥ 40 years. Cross-sectional variation and longitudinal changes in capacity were examined in relation to county characteristics.Between 2000 and 2010, the number of mammography facilities declined 10% from 9434 to 8469, the number of mammography machines declined 10% from 13,100 to 11,762, and the median county mammography capacity decreased nearly 20% from 1.77 to 1.42 machines per 10,000 women aged ≥ 40 years. In cross-sectional analysis, counties with greater percentages of uninsured residents, less educated residents, greater population density, and higher managed care penetration had lower mammography capacity. Conversely, counties with more hospital beds per 100,000 population had higher capacity. High initial mammography capacity, growth in both the percentage of the population aged ≥ 65 years and the percentage living in poverty, and increased managed care penetration were all associated with a decrease in mammography capacity between 2000 and 2010. Only the percentage of rural residents was associated with an increase in capacity.Geographic variation in mammography capacity and declines in capacity over time are associated with demographic, socioeconomic, and health care market characteristics. Maldistribution of mammography resources may explain geographic disparities in breast cancer screening rates.

Randomized trials report equivalent efficacy among various combinations of platinum-based regimens in advanced non-small cell lung cancer (NSCLC). Their relative effectiveness and comparability based on squamous versus nonsquamous histology is uncertain.The authors used the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data to identify first-line chemotherapy agents administered to Medicare beneficiaries with stage IIIB or IV NSCLC diagnosed from 2000 to 2007. Overall survival was compared between patients who received the 3 most common regimens: carboplatin-paclitaxel, carboplatin-gemcitabine, and carboplatin-docetaxel. Stratified analyses distinguished between the outcomes of patients with squamous versus nonsquamous cell histology. Multivariable Cox proportional hazards models and propensity score analyses facilitated adjustment for imbalance in measurable patient characteristics.Of the 15,318 patients who received first-line chemotherapy, 43.1% received carboplatin-paclitaxel, 14.3% received carboplatin-gemcitabine, 8.5% received carboplatin-docetaxel, and 34.1% received other regimens. The median survival was 8.0 months (interquartile range [IQR], 3.5-17.4 months) for carboplatin-paclitaxel, 7.3 months (IQR, 3.4-15.2 months) for carboplatin-gemcitabine, and 7.5 months (IQR, 3.2-16.0 months) for carboplatin-docetaxel. Both multivariable and propensity score-adjusted Cox models demonstrated a slight inferiority associated with carboplatin-gemcitabine or carboplatin-docetaxel versus carboplatin-paclitaxel, with a hazard ratio of 1.10 (95% confidence interval, 1.04-1.15) and 1.09 (95% confidence interval, 1.02-1.16), respectively, in propensity score-stratified models. Among the subgroup of 2063 patients with squamous carcinoma, propensity score-stratified analyses had a higher risk of death (hazard ratio, 1.20; 95% confidence interval, 1.07-1.35) associated with carboplatin-gemcitabine versus carboplatin-paclitaxel.Carboplatin-paclitaxel was associated with slightly better survival compared with carboplatin-gemcitabine or carboplatin-docetaxel within the Medicare population with advanced NSCLC, and this was most pronounced for patients who had squamous cell histology.

BACKGROUND: Little is known about the impact of direct-to-consumer advertising (DTCA) on appropriate versus inappropriate prescribing. Aromatase inhibitor (AI) therapy for breast cancer provides an ideal paradigm for studying this issue, because AIs have been the focus of substantial DTCA, and because they should only be used in postmenopausal women, age can serve as a simple surrogate marker of appropriateness. METHODS: Data regarding national DTCA spending for the AIs were obtained from TNS Multimedia; hormonal therapy prescription data were obtained from IMS Health. Time series analyses were performed to characterize the association between monthly changes in DTCA spending for the AIs and monthly changes in the proportion of all new hormonal therapy prescriptions represented by the AIs from October 2005 to September 2007. Analyses were stratified by age, considering prescriptions for women ≤ 40 (likely premenopausal) to be inappropriate and those for women > 60 (likely postmenopausal) to be appropriate. RESULTS: Monthly dollars spent on AI-associated DTCA varied considerably ($118,600 to $22,019,660). Time series analysis revealed that for every million dollars spent on DTCA for the AIs, there was an associated increase 3 months later in the new AI prescription proportion of 0.15% for all ages (P 60 years (P < .0001), but no significant change for those ≤ 40 at any time from 0 to 6 months. CONCLUSIONS: DTCA for the AIs was associated with increases in appropriate prescriptions with no significant effect on inappropriate prescriptions, suggesting that DTCA may not foster inappropriate medication use for certain drug classes.

BACKGROUND: Population-based cancer registries that include patient follow-up generally provide information regarding net survival (ie, survival associated with the risk of dying of cancer in the absence of competing risks). However, registry data also can be used to calculate survival from cancer in the presence of competing risks, which is more clinically relevant. METHODS: Statistical methods were developed to predict the risk of death from cancer and other causes, as well as natural life expectancy if the patient did not have cancer based on a profile of prognostic factors including characteristics of the cancer, demographic factors, and comorbid conditions. The Surveillance, Epidemiology, and End Results (SEER) Program database was used to calculate the risk of dying of cancer. Because the risks of dying of cancer versus other causes are assumed to be independent conditional on the prognostic factors, a wide variety of independent data sources can be used to calculate the risk of death from other causes. Herein, the risk of death from other causes was estimated using SEER and Medicare claims data, and was matched to the closest fitting portion of the US life table to obtain a “health status-adjusted age.” RESULTS: A nomogram was developed for prostate cancer as part of a Web-based Cancer Survival Query System that is targeted for use by physicians and patients to obtain information on a patient's prognosis. More nomograms currently are being developed. CONCLUSIONS: Nomograms of this type can be used as one tool to assist cancer physicians and their patients to better understand their prognosis and to weigh alternative treatment and palliative strategies.
