RESUMEN

Objective: To evaluate whether integrating breast and cervical cancer screening in Rwanda's Women's Cancer Early Detection Program led to early breast cancer diagnoses in asymptomatic women. Methods: Launched in three districts in 2018-2019, the early detection programme offered clinical breast examination screening for all women receiving cervical cancer screening, and diagnostic breast examination for women with breast cancer symptoms. Women with abnormal breast examinations were referred to district hospitals and then to referral hospitals if needed. We examined how often clinics were held, patient volumes and number of referrals. We also examined intervals between referrals and visits to the next care level and, among women diagnosed with cancer, their initial reasons for seeking care. Findings: Health centres held clinics > 68% of the weeks. Overall, 9763 women received cervical cancer screening and clinical breast examination and 7616 received breast examination alone. Of 585 women referred from health centres, 436 (74.5%) visited the district hospital after a median of 9 days (interquartile range, IQR: 3-19). Of 200 women referred to referral hospitals, 179 (89.5%) attended after a median of 11 days (IQR: 4-18). Of 29 women diagnosed with breast cancer, 19 were ≥ 50 years and 23 had stage III or stage IV disease. All women with breast cancer whose reasons for seeking care were known (23 women) had experienced breast cancer symptoms. Conclusion: In the short-term, integrating clinical breast examination with cervical cancer screening was not associated with detection of early-stage breast cancer among asymptomatic women. Priority should be given to encouraging women to seek timely care for symptoms.

RESUMEN

PURPOSE: To characterize racial and ethnic disparities and trends in opioid access and urine drug screening (UDS) among patients dying of cancer, and to explore potential mechanisms. METHODS: Among 318,549 non-Hispanic White (White), Black, and Hispanic Medicare decedents older than 65 years with poor-prognosis cancers, we examined 2007-2019 trends in opioid prescription fills and potency (morphine milligram equivalents [MMEs] per day [MMEDs]) near the end of life (EOL), defined as 30 days before death or hospice enrollment. We estimated the effects of race and ethnicity on opioid access, controlling for demographic and clinical factors. Models were further adjusted for socioeconomic factors including dual-eligibility status, community-level deprivation, and rurality. We similarly explored disparities in UDS. RESULTS: Between 2007 and 2019, White, Black, and Hispanic decedents experienced steady declines in EOL opioid access and rapid expansion of UDS. Compared with White patients, Black and Hispanic patients were less likely to receive any opioid (Black, -4.3 percentage points, 95% CI, -4.8 to -3.6; Hispanic, -3.6 percentage points, 95% CI, -4.4 to -2.9) and long-acting opioids (Black, -3.1 percentage points, 95% CI, -3.6 to -2.8; Hispanic, -2.2 percentage points, 95% CI, -2.7 to -1.7). They also received lower daily doses (Black, -10.5 MMED, 95% CI, -12.8 to -8.2; Hispanic, -9.1 MMED, 95% CI, -12.1 to -6.1) and lower total doses (Black, -210 MMEs, 95% CI, -293 to -207; Hispanic, -179 MMEs, 95% CI, -217 to -142); Black patients were also more likely to undergo UDS (0.5 percentage points; 95% CI, 0.3 to 0.8). Disparities in EOL opioid access and UDS disproportionately affected Black men. Adjustment for socioeconomic factors did not attenuate the EOL opioid access disparities. CONCLUSION: There are substantial and persistent racial and ethnic inequities in opioid access among older patients dying of cancer, which are not mediated by socioeconomic variables.

RESUMEN

PURPOSE: To support shared decision-making, patient-facing resources are needed to complement recently published guidelines on approaches for surveillance mammography in breast cancer survivors aged ≥ 75 or with < 10-year life expectancy. We created a patient guide to facilitate discussions about surveillance mammography in older breast cancer survivors. METHODS: The "Are Mammograms Still Right for Me?" guide estimates future ipsilateral and contralateral breast (in-breast) cancer risks, general health, and the potential benefits/harms of mammography, with prompts for discussion. We conducted in-clinic acceptability testing of the guide by survivors and their clinicians at a National Cancer Institute-designated comprehensive cancer center, including two community practices. Patients and clinicians received the guide ahead of a clinic visit and surveyed patients (pre-/post-visit) and clinicians (post-visit). Acceptability was defined as ≥ 75% of patients and clinicians reporting that the guide (a) should be recommended to others, (b) is clear, (c) is helpful, and (d) contains a suitable amount of information. We also elicited feedback on usability and mammography intentions. RESULTS: We enrolled 45 patients and their 21 clinicians. Among those responding in post-visit surveys, 33/37 (89%) patients and 15/16 (94%) clinicians would recommend the guide to others; 33/37 (89%) patients and 15/16 (94%) clinicians felt everything/most things were clear. All other pre-specified acceptability criteria were met. Most patients reported strong intentions for mammography (100% pre-visit, 98% post-visit). CONCLUSION: Oncology clinicians and older breast cancer survivors found a guide to inform mammography decision-making acceptable and clear. A multisite clinical trial is needed to assess the guide's impact mammography utilization. TRIAL REGISTRATION: ClinicalTrials.gov-NCT03865654, posted March 7, 2019.

RESUMEN

The aim was to examine the association of patient-reported physician awareness of biological CAM use and patient perceptions of care experience and quality with a population-based study of patients with incident lung and colorectal cancer. This was a secondary data analysis using regression models. Outcomes of interest were patient reports of medical care experience and quality ratings. Among 716 patients who reported biological CAM use, 69% reported their physicians were aware of this. Patients who reported physician awareness of biological CAM use had higher adjusted scores for medical care experience ( + 5.4, 95%CI:2.3,8.6) and care quality ( + 3.6, 95%CI:-0.3, + 7.5). These associations suggest that physicians should be encouraged to inquire about biological CAM use.

RESUMEN

PURPOSE: Genomic testing improves outcomes for many at-risk individuals and patients with cancer; however, little is known about how genomic testing for non-small-cell lung cancer (NSCLC) and colorectal cancer (CRC) is used in clinical practice. PATIENTS AND METHODS: In 2012 to 2013, we surveyed medical oncologists who care for patients in diverse practice and health care settings across the United States about their use of guideline- and non-guideline-endorsed genetic tests. Multivariable regression models identified factors that are associated with greater test use. RESULTS: Of oncologists, 337 completed the survey (participation rate, 53%). Oncologists reported higher use of guideline-endorsed tests (eg, KRAS for CRC; EGFR for NSCLC) than non-guideline-endorsed tests (eg, Onco typeDX Colon; ERCC1 for NSCLC). Many oncologists reported having no patients with CRC who had mismatch repair and/or microsatellite instability (24%) or germline Lynch syndrome (32%) testing, and no patients with NSCLC who had ALK testing (11%). Of oncologists, 32% reported that five or fewer patients had KRAS and EGFR testing for CRC and NSCLC, respectively. Oncologists, rather than pathologists or surgeons, ordered the vast majority of tests. In multivariable analyses, fewer patients in nonprofit integrated health care delivery systems underwent testing than did patients in hospital or office-based single-specialty group settings (all P < .05). High patient volume and patient requests (CRC only) were also associated with higher test use (all P < .05). CONCLUSION: Genomic test use for CRC and NSCLC varies by test and practice characteristics. Research in specific clinical contexts is needed to determine whether the observed variation reflects appropriate or inappropriate care. One potential way to reduce unwanted variation would be to offer widespread reflexive testing by pathology for guideline-endorsed predictive somatic tests.

RESUMEN

PURPOSE: The optimal use of androgen deprivation therapy as salvage treatment (sADT) for men after initial prostatectomy or radiotherapy for clinically localized prostate cancer is undefined. We describe patterns of sADT use and investigate clinical and sociodemographic characteristics of insured men who received sADT versus surveillance in managed care settings. METHODS: Using comprehensive electronic health records and cancer registry data from three integrated health plans, we identified all men with newly diagnosed clinically localized prostate cancer between 1995 and 2009 who received either prostatectomy (n = 16,445) or radiotherapy (n = 19,531) as their primary therapy. We defined sADT based on the timing of ADT following primary therapy and stage of cancer. We fit Cox proportional hazard models to identify sociodemographic characteristics and clinical factors associated with sADT. RESULTS: With a median follow-up of 6 years (range 2-15 years), 13 % of men who underwent primary prostatectomy or radiotherapy received sADT. After adjusting for selected covariates, sADT was more likely to be used in men who were older (e.g., HR 1.70, 95 % CI 1.48-1.96 or HR 1.33, 95 % CI 1.17-1.52 for age 70+ relative to age 35-59 for primary prostatectomy or radiotherapy, respectively), were African-American, had a short PSA doubling time, had a higher pre-treatment risk of progression, had more comorbidities, and received adjuvant ADT for initial disease. CONCLUSIONS: In men with localized prostate cancer in community practice initially treated with prostatectomy or radiotherapy, sADT after primary treatment was more frequent for men at greater risk of death from prostate cancer, consistent with practice guidelines.

RESUMEN

PURPOSE: A 2006 randomized trial demonstrated a 16-month survival benefit with intraperitoneal and intravenous (IP/IV) chemotherapy administered to patients who had ovarian cancer, compared with IV chemotherapy alone, but more treatment-related toxicities. The objective of this study was to examine the use and effectiveness of IP/IV chemotherapy in clinical practice. PATIENTS AND METHODS: Prospective cohort study of 823 women with stage III, optimally cytoreduced ovarian cancer diagnosed at six National Comprehensive Cancer Network institutions. We examined IP/IV chemotherapy use in all patients diagnosed between 2003 and 2012 (N = 823), and overall survival and treatment-related toxicities with Cox regression and logistic regression, respectively, in a propensity score-matched sample (n = 402) of patients diagnosed from 2006 to 2012, excluding trial participants, to minimize selection bias. RESULTS: Use of IP/IV chemotherapy increased from 0% to 33% between 2003 and 2006, increased to 50% from 2007 to 2008, and plateaued thereafter. Between 2006 and 2012, adoption of IP/IV chemotherapy varied by institution from 4% to 67% (P < .001) and 43% of patients received modified IP/IV regimens at treatment initiation. In the propensity score-matched sample, IP/IV chemotherapy was associated with significantly improved overall survival (3-year overall survival, 81% v 71%; hazard ratio, 0.68; 95% CI, 0.47 to 0.99), compared with IV chemotherapy, but also more frequent alterations in chemotherapy delivery route (adjusted rates discontinuation or change, 20.4% v 10.0%; adjusted odds ratio, 2.83; 95% CI, 1.47 to 5.47). CONCLUSION: Although the use of IP/IV chemotherapy increased significantly at National Comprehensive Cancer Network centers between 2003 and 2012, fewer than 50% of eligible patients received it. Increasing IP/IV chemotherapy use in clinical practice may be an important and underused strategy to improve ovarian cancer outcomes.

RESUMEN

BACKGROUND: Breast cancer incidence is increasing in low- and middle-income countries (LMICs). Mortality/incidence ratios in LMICs are higher than in high-income countries, likely at least in part because of delayed diagnoses leading to advanced-stage presentations. In the present study, we investigated the magnitude, impact of, and risk factors for, patient and system delays in breast cancer diagnosis in Rwanda. MATERIALS AND METHODS: We interviewed patients with breast complaints at two rural Rwandan hospitals providing cancer care and reviewed their medical records to determine the diagnosis, diagnosis date, and breast cancer stage. RESULTS: A total of 144 patients were included in our analysis. Median total delay was 15 months, and median patient and system delays were both 5 months. In multivariate analyses, patient and system delays of ≥6 months were significantly associated with more advanced-stage disease. Adjusting for other social, demographic, and clinical characteristics, a low level of education and seeing a traditional healer first were significantly associated with a longer patient delay. Having made ≥5 health facility visits before the diagnosis was significantly associated with a longer system delay. However, being from the same district as one of the two hospitals was associated with a decreased likelihood of system delay. CONCLUSION: Patients with breast cancer in Rwanda experience long patient and system delays before diagnosis; these delays increase the likelihood of more advanced-stage presentations. Educating communities and healthcare providers about breast cancer and facilitating expedited referrals could potentially reduce delays and hence mortality from breast cancer in Rwanda and similar settings. IMPLICATIONS FOR PRACTICE: Breast cancer rates are increasing in low- and middle-income countries, and case fatality rates are high, in part because of delayed diagnosis and treatment. This study examined the delays experienced by patients with breast cancer at two rural Rwandan cancer facilities. Both patient delays (the interval between symptom development and the patient's first presentation to a healthcare provider) and system delays (the interval between the first presentation and diagnosis) were long. The total delays were the longest reported in published studies. Longer delays were associated with more advanced-stage disease. These findings suggest that an opportunity exists to reduce breast cancer mortality in Rwanda by addressing barriers in the community and healthcare system to promote earlier detection.

RESUMEN

OBJECTIVE: To assess the extent to which patients self-refer to cancer specialists and whether self-referral is associated with better experiences and quality of care. DATA SOURCES: Data from surveys and medical record abstraction collected through the Cancer Care Outcomes Research and Surveillance Consortium. STUDY DESIGN: Observational study of patients with lung and colorectal cancer diagnosed from 2003 through 2005 in five geographically defined regions and five integrated health care delivery systems. METHODS: Multivariable logistic regression models used to assess factors associated with self-referral and propensity score-weighted doubly robust models to test the association between self-referral and experiences/quality of care. PRINCIPAL FINDINGS: Among 5,882 patients, 9.7 percent of lung cancer patients and 14.9 percent of colorectal cancer patients self-referred to at least one cancer specialist. Black patients were less likely to self-refer than white patients (odds ratio: 0.48, 95 percent confidence interval: 0.35, 0.64); patients with high incomes (vs. low) and with a college degree (vs. non-high school graduates) were significantly more likely to self-refer. Self-referral was associated with lower ratings of overall physician communication for patients with lung cancer but, conversely, higher odds of curative surgery among patients with stage I/II lung cancer. CONCLUSIONS: A small but significant proportion of patients self-referred to their cancer specialists; rates varied by patient race and socioeconomic status. To the extent that self-referral is associated with quality, it may reinforce disparities in care.

RESUMEN

OBJECTIVE: Black and Hispanic individuals synthesize less vitamin D per unit of sun exposure than white individuals. The relationship between UV radiation and vitamin D insufficiency in minorities has not been well explored. DESIGN: Prospective cohort study. SETTING: Using the National Health and Nutrition Examination Survey, we obtained serum vitamin D levels for non-Hispanic Whites, Hispanics and non-Hispanic Blacks aged ≥18 years from 2000-2006. We linked these data with the average monthly solar UV index by census tract and data on sun exposure, vitamin D supplementation, health and demographics. We used multivariable regression analyses to assess vitamin D deficiency (<15 ng/ml) and insufficiency (<20 ng/ml) in January (when the UV index was lowest) by race/ethnicity and geography. SUBJECTS: Adults (n 14,319) aged ≥18 years. RESULTS: A 1-point increase in the UV index was associated with a 0·51 ng/ml increase in vitamin D (95% CI 0·35, 0·67 ng/ml; P<0·001). Non-Hispanic Black race and Hispanic ethnicity were associated with a 7·47 and 3·41 ng/ml decrease in vitamin D, respectively (both P<0·001). In January, an estimated 65·4% of non-Hispanic Blacks were deficient in vitamin D, compared with 28·9% of Hispanics and 14·0% of non-Hispanic Whites. An estimated 84·2% of non-Hispanic Blacks were insufficient in vitamin D v. 56·3% of Hispanics and 34·8% of non-Hispanic Whites. More non-Hispanic Blacks were estimated to be deficient in vitamin D in January in the highest UV index quartile than were non-Hispanic Whites in the lowest UV index quartile (60·2% v. 25·7%). CONCLUSIONS: Wintertime vitamin D insufficiency is pervasive among minority populations, and not uncommon among non-Hispanic Whites.

RESUMEN

PURPOSE: The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) decreased fee-for-service (FFS) payments for outpatient chemotherapy. We assessed how this policy affected chemotherapy in FFS settings versus in integrated health networks (IHNs). PATIENTS AND METHODS: We examined 5,831 chemotherapy regimens for 3,613 patients from 2003 to 2006 with colorectal cancer (CRC) or lung cancers in the Cancer Care Outcomes Research Surveillance Consortium. Patients were from four geographically defined regions, seven large health maintenance organizations, and 15 Veterans Affairs Medical Centers. The outcome of interest was receipt of chemotherapy that included at least one drug for which reimbursement declined after the MMA. RESULTS: The odds of receiving an MMA-affected drug were lower in the post-MMA era: the odds ratio (OR) was 0.73 (95% CI, 0.59 to 0.89). Important differences across cancers were detected: for CRC, the OR was 0.65 (95% CI, 0.46 to 0.92); for non-small-cell lung cancer (NSCLC), the OR was 1.60 (95% CI, 1.09 to 2.35); and for small-cell lung cancer, the OR was 0.63 (95% CI, 0.34 to 1.16). After the MMA, FFS patients were less likely to receive MMA-affected drugs: OR, 0.73 (95% CI, 0.59 to 0.89). No pre- versus post-MMA difference in the use of MMA-affected drugs was detected among IHN patients: OR, 1.01 (95% CI, 0.66 to 1.56). Patients with CRC were less likely to receive an MMA-affected drug in both FFS and IHN settings in the post- versus pre-MMA era, whereas patients with NSCLC were the opposite: OR, 1.60 (95% CI, 1.09 to 2.35) for FFS and 6.33 (95% CI, 2.09 to 19.11) for IHNs post- versus pre-MMA. CONCLUSION: Changes in reimbursement after the passage of MMA appear to have had less of an impact on prescribing patterns in FFS settings than the introduction of new drugs and clinical evidence as well as other factors driving adoption of new practice patterns.

RESUMEN

Multidisciplinary management tumor boards are now conducted worldwide for the management of patients with cancer. Studies evaluating their influence on decision making and patient outcome are limited; however, single-center studies have reported significant changes in diagnosis and treatment plans. A survey from Arabic countries showed widespread use and reliance on tumor boards for decision making. A recent multi-institutional survey of veteran affairs (VA) hospitals in the United States found limited association between the presence of tumor boards and care and outcomes. The Cancer Care Outcomes Research and Surveillance Consortium looked at the association between tumor board features and measures of quality of care. Results of overall survival among the patients of these physicians participating in tumor boards is ongoing, but preliminary results are outlined along with a recent ASCO survey of international members on the presence, utilization, and influence of tumor boards in this article. Tumor boards allow for implementation of clinical practice guidelines and may help capture cases for clinical trials. Efforts to improve preparations, structure, and conduct of tumor boards, research methods to monitor their performance, teamwork, and outcomes are outlined also in this article. The concept of mini-tumor boards and more efficient methods for MDM in countries with limited resources are also discussed. In suboptimal settings, such as small community hospitals, rural areas, and areas with limited resources, boundaries in diagnosis and management can be overcome, or at least improved, with tumor boards, especially with the use of video-conferencing facilities. Studies from the United Kingdom showed that special training of multidisciplinary teams (MDT) led to better team dynamics and communication, improved patient satisfaction, and improved clinical outcome. The weight of the benefits versus the time and effort spent to improve efficiency, patient care, and better time management in the United States and in the international oncology community is also reviewed in this article.

RESUMEN

PURPOSE: Primary androgen-deprivation therapy (PADT) is often used to treat clinically localized prostate cancer, but its effects on cause-specific and overall mortality have not been established. Given the widespread use of PADT and the potential risks of serious adverse effects, accurate mortality data are needed to inform treatment decisions. METHODS: We conducted a retrospective cohort study using comprehensive utilization and cancer registry data from three integrated health plans. All men were newly diagnosed with clinically localized prostate cancer. Men who were diagnosed between 1995 and 2008, were not treated with curative intent therapy, and received follow-up through December 2010 were included in the study (n = 15,170). We examined all-cause and prostate cancer-specific mortality as our main outcomes. We used Cox proportional hazards models with and without propensity score analysis. RESULTS: Overall, PADT was associated with neither a risk of all-cause mortality (hazard ratio [HR], 1.04; 95% CI, 0.97 to 1.11) nor prostate-cancer-specific mortality (HR, 1.03; 95% CI, 0.89 to 1.19) after adjusting for all sociodemographic and clinical characteristics. PADT was associated with decreased risk of all-cause mortality but not prostate-cancer-specific mortality. PADT was associated with decreased risk of all-cause mortality only among the subgroup of men with a high risk of cancer progression (HR, 0.88; 95% CI, 0.78 to 0.97). CONCLUSION: We found no mortality benefit from PADT compared with no PADT for most men with clinically localized prostate cancer who did not receive curative intent therapy. Men with higher-risk disease may derive a small clinical benefit from PADT. Our study provides the best available contemporary evidence on the lack of survival benefit from PADT for most men with clinically localized prostate cancer.

RESUMEN

Cognitive changes in older women receiving chemotherapy are poorly understood. We examined self-reported cognitive function for older women who received adjuvant chemotherapy on Cancer and Leukemia Group B (CALGB) 49907. CALGB 49907 randomized 633 women aged ≥65 with stage I-III breast cancer to standard adjuvant chemotherapy (cyclophosphamide-methotrexate-5-fluorouracil or doxorubicin-cyclophosphamide) versus capecitabine. We examined self-reported cognitive function in 297 women (CALGB 361002) who enrolled on the quality of life substudy and had no gross impairment on cognitive screening. Women were evaluated using an 18-item instrument at six time points (baseline through 24 months). At each time point for each patient, we calculated a cognitive function score (CFS) defined as the mean response of items 1-18 and defined impairment as a score >1.5 standard deviations above the overall average baseline score. Differences in scores by patient characteristics were evaluated using a Kruskal-Wallis test. A linear mixed-effects model was used to assess CFSs by treatment over time. Among 297 women, the median age was 71.5 (range 65-85) and 73 % had performance status of 0. Baseline depression and fatigue were reported in 6 and 14 % of patients, respectively. The average CFS at baseline was 2.08 (corresponding to "normal ability"), and baseline cognitive function did not differ by treatment regimen (p = 0.350). Over 24 months, women reported minimal changes at each time point and insignificant differences by treatment arm were observed. In a healthy group of older women, chemotherapy was not associated with longitudinal changes in self-reported cognitive function.

RESUMEN

BACKGROUND: Trastuzumab for human epidermal growth factor receptor 2 (HER2)-positive breast cancer is highly efficacious yet costly and time-intensive, and few data are available about its use. The authors of this report examined receipt and completion of adjuvant trastuzumab by race/ethnicity and education for women with HER2-positive disease. METHODS: The National Comprehensive Cancer Network Breast Cancer Outcomes Database was used to identify 1109 women who were diagnosed with stage I through III, HER2-positive breast cancer during September 2005 through December 2008 and were followed for ≥1 year. The authors used multivariable logistic regression to assess the association of race/ethnicity and education with the receipt of trastuzumab and, among those women who initiated trastuzumab, with the completion of > 270 days of therapy. RESULTS: The cohort was 75% white, 8% black, and 9% Hispanic; and 20% of women had attained a high school degree or less. Most women (83%) received trastuzumab, and no significant differences were observed according to race/ethnicity or socioeconomic status. Among the women who initiated trastuzumab, 73% of black women versus 87% of white women (P = .007) and 70% of women with less than a high school education versus 90% of women with a college degree completed > 270 days of therapy (P = .006). In adjusted analyses, black women (vs white women) and women without a high school degree (vs those with a college degree) had lower odds of completing therapy (black women: odds ratio, 0.45; 95% confidence interval, 0.27-074; white women: odds ratio, 0.27, 95% confidence interval, 0.14-0.51). CONCLUSIONS: Differences in completing trastuzumab therapy were observed according to race and educational attainment among women who received treatment at National Comprehensive Cancer Network centers. Efforts to assure the appropriate use of trastuzumab and to understand treatment barriers are needed and may lead to improved outcomes. The authors report differences in the rate at which patients complete treatment with trastuzumab according to race and education among women who receive treatment at National Comprehensive Cancer Network centers. Efforts to assure the appropriate use of trastuzumab and to understand treatment barriers are needed and may lead to improved outcomes.

RESUMEN

BACKGROUND: The Veterans Health Administration (VHA) is the largest integrated health care system in the United States. Studies suggest that the VHA provides better preventive care and care for some chronic illnesses than does the private sector. OBJECTIVE: To assess the quality of cancer care for older patients provided by the VHA versus fee-for-service Medicare. DESIGN: Observational study of patients with cancer that was diagnosed between 2001 and 2004 who were followed through 2005. SETTING: VHA and non-VHA hospitals and office-based practices. PATIENTS: Men older than 65 years with incident colorectal, lung, or prostate cancer; lymphoma; or multiple myeloma. MEASUREMENTS: Rates of processes of care for colorectal, lung, or prostate cancer; lymphoma; or multiple myeloma. Rates were adjusted by using propensity score weighting. RESULTS: Compared with the fee-for-service Medicare population, the VHA population received diagnoses of colon (P < 0.001) and rectal (P = 0.007) cancer at earlier stages and had higher adjusted rates of curative surgery for colon cancer (92.7% vs. 90.5%; P < 0.010), standard chemotherapy for diffuse large B-cell non-Hodgkin lymphoma (71.1% vs. 59.3%; P < 0.001), and bisphosphonate therapy for multiple myeloma (62.1% vs. 50.4%; P < 0.001). The VHA population had lower adjusted rates of 3-dimensional conformal or intensity-modulated radiation therapy for prostate cancer treated with external-beam radiation therapy (61.6% vs. 86.0%; P < 0.001). Adjusted rates were similar for 9 other measures. Sensitivity analyses suggest that if patients with cancer in the VHA system have more severe comorbid illness than other patients, rates for most indicators would be higher in the VHA population than in the fee-for-service Medicare population. LIMITATION: This study included only older men and did not include information about performance status, severity of comorbid illness, or patient preferences. CONCLUSION: Care for older men with cancer in the VHA system was generally similar to or better than care for fee-for-service Medicare beneficiaries, although adoption of some expensive new technologies may be delayed in the VHA system.

RESUMEN

BACKGROUND: Few studies have assessed associations of surgeons' practice volume with processes of care that lead to better outcomes. OBJECTIVE: We surveyed surgeons treating colorectal cancer to determine whether high-volume surgeons were more likely to collaborate with other physicians in decisions about adjuvant therapies. SUBJECTS AND METHODS: Surgeons caring for patients with colorectal cancer in multiple regions and health-care organizations were surveyed to assess their volume of colorectal cancer resections and participation in decisions about adjuvant chemotherapy and radiation therapy. We used logistic regression to assess physician and practice characteristics associated with surgical volume and the relation of surgical volume and these other characteristics to collaborative decision-making regarding adjuvant therapies. RESULTS: Of 635 responding surgeons, those who identified themselves as surgical oncologists or colorectal surgeons were more likely than others to report high volume of colorectal cancer resections (P < 0.001), as were those who practiced at a comprehensive cancer center (P = 0.06) and attended tumor board meetings weekly (vs. quarterly or less, P = 0.09). Most surgeons reported a collaborative role in decisions about chemotherapy and radiation therapy. However, in adjusted analyses, higher-volume surgeons more often reported a collaborative role with other physicians in decisions about chemotherapy (P < 0.001) and radiation therapy (P < 0.001). CONCLUSIONS: Higher-volume surgeons are more likely to report collaborating with other physicians in decisions about adjuvant therapies for patients following colorectal cancer surgery. This collaborative decision-making of higher-volume surgeons may contribute to outcome differences by surgeon volume.

RESUMEN

CONTEXT: Minimally invasive radical prostatectomy (MIRP) has diffused rapidly despite limited data on outcomes and greater costs compared with open retropubic radical prostatectomy (RRP). OBJECTIVE: To determine the comparative effectiveness of MIRP vs RRP. DESIGN, SETTING, AND PATIENTS: Population-based observational cohort study using US Surveillance, Epidemiology, and End Results Medicare linked data from 2003 through 2007. We identified men with prostate cancer who underwent MIRP (n = 1938) vs RRP (n = 6899). MAIN OUTCOME MEASURES: We compared postoperative 30-day complications, anastomotic stricture 31 to 365 days postoperatively, long-term incontinence and erectile dysfunction more than 18 months postoperatively, and postoperative use of additional cancer therapies, a surrogate for cancer control. RESULTS: Among men undergoing prostatectomy, use of MIRP increased from 9.2% (95% confidence interval [CI], 8.1%-10.5%) in 2003 to 43.2% (95% CI, 39.6%-46.9%) in 2006-2007. Men undergoing MIRP vs RRP were more likely to be recorded as Asian (6.1% vs 3.2%), less likely to be recorded as black (6.2% vs 7.8%) or Hispanic (5.6% vs 7.9%), and more likely to live in areas with at least 90% high school graduation rates (50.2% vs 41.0%) and with median incomes of at least $60,000 (35.8% vs 21.5%) (all P < .001). In propensity score-adjusted analyses, MIRP vs RRP was associated with shorter length of stay (median, 2.0 vs 3.0 days; P<.001) and lower rates of blood transfusions (2.7% vs 20.8%; P < .001), postoperative respiratory complications (4.3% vs 6.6%; P = .004), miscellaneous surgical complications (4.3% vs 5.6%; P = .03), and anastomotic stricture (5.8% vs 14.0%; P < .001). However, MIRP vs RRP was associated with an increased risk of genitourinary complications (4.7% vs 2.1%; P = .001) and diagnoses of incontinence (15.9 vs 12.2 per 100 person-years; P = .02) and erectile dysfunction (26.8 vs 19.2 per 100 person-years; P = .009). Rates of use of additional cancer therapies did not differ by surgical procedure (8.2 vs 6.9 per 100 person-years; P = .35). CONCLUSION: Men undergoing MIRP vs RRP experienced shorter length of stay, fewer respiratory and miscellaneous surgical complications and strictures, and similar postoperative use of additional cancer therapies but experienced more genitourinary complications, incontinence, and erectile dysfunction.

RESUMEN

BACKGROUND: Previous studies have documented that hospice enrollment by terminally ill cancer patients varies substantially by patient characteristics and across broad geographic regions, but little is known about how local practice patterns and individual physicians contribute to these variations. We examined hospice use within a regional integrated health care delivery system that provides consistent insurance coverage and hospice availability for its members to evaluate the relative importance of patient characteristics, physician characteristics, individual physicians, and local health centers in explaining variations in hospice enrollment. METHODS: We examined data for 3805 Kaiser Permanente of Northern California health plan enrollees who were diagnosed with and died of lung, colorectal, breast, or prostate cancer from January 1, 1996, through June 30, 2001. We used a random-effects linear probability hierarchical model to estimate adjusted hospice enrollment rates and identify factors associated with hospice enrollment. All P values are two-sided. RESULTS: Overall, 65.4% of patients enrolled in hospice care before death. In adjusted analyses, hospice enrollment did not vary by patients' race/ethnicity or marital status (all P>.2) but varied substantially among the 11 health centers where patients were treated (standard deviation [SD] of random effect = 10.0 percentage points, corresponding to an estimated adjusted hospice enrollment rate for two-thirds of centers (2 SDs) ranging from 55% to 75%, P = .02). Hospice enrollment varied less among the 675 individual physicians (SD = 4.6 percentage points; P = .09). CONCLUSIONS: Health care within a large integrated delivery system has the potential to eliminate racial and ethnic disparities in hospice use, but substantial variation in hospice use persists among local health centers. Focused efforts to understand how patients, physicians, and hospices interact at the local level are important to ensure equal access to hospice care for all terminally ill cancer patients.
