PURPOSE After the National Institutes of Health Consensus Statement in 1990, breast-conserving surgery (BCS) became more common while mastectomy rates decreased. However, several recently published single-institution studies have reported an increase in mastectomy rates in the past decade. We conducted a population-based study to evaluate national trends in the surgical treatment of breast cancer from 2000 through 2006. PATIENTS AND METHODS Using the Surveillance, Epidemiology, and End Results database, we conducted a retrospective cohort analysis of women undergoing surgical treatment for breast cancer. We evaluated variation in mastectomy rates by demographic and tumor factors and calculated differences in mastectomy rates across time. We utilized logistic regression to identify time trends and patient and tumor factors associated with mastectomy, testing for significance using two-sided methods. RESULTS We identified 233,754 patients diagnosed with ductal carcinoma in situ or stage I to III unilateral breast cancer from 2000 to 2006. The proportion of women treated with mastectomy decreased from 40.8% in 2000 to 37.0% in 2006 (P < .001). These patterns were maintained across patient and tumor factors. Although the unilateral mastectomy rate decreased during the study period, the contralateral prophylactic mastectomy rate increased. Women were less likely to receive mastectomy over time (odds ratio, 1.18 for 2000 v 2006; 95% CI, 1.14 to 1.23; P < .0001), after adjusting for patient and tumor factors. CONCLUSION In contrast to single-institution studies, our population-based analysis found a decrease in unilateral mastectomy rates from 2000 to 2006 in the United States. Variations in referral patterns and patient selection are potential explanations for these differences between single institutions and national trends.

CONTEXT Among patients surgically treated for colon cancer, better survival has been demonstrated in those with more lymph nodes evaluated. The presumed mechanism behind this association suggests that a more extensive lymph node evaluation reduces the risk of understaging, leading to improved survival. OBJECTIVE To further evaluate the mechanism behind lymph node evaluation and survival by examining the association between more extensive lymph node evaluation, identification of lymph node-positive cancers, and hazard of death. DESIGN Observational cohort study. SETTING Surveillance, Epidemiology, and End Results (SEER) program data from 1988 through 2008. PATIENTS 86,394 patients surgically treated for colon cancer. MAIN OUTCOME MEASURE We examined the relationship between lymph node evaluation and node positivity using Cochran-Armitage tests and multivariate logistic regression. The association between lymph node evaluation and hazard of death was evaluated using Cox proportional hazards modeling. RESULTS The number of lymph nodes evaluated increased from 1988 to 2008 but did not result in a significant overall increase in lymph node positivity. During 1988-1990, 34.6% of patients (3875/11,200) had 12 or more lymph nodes evaluated, increasing to 73.6% (9798/13,310) during 2006-2008 (P < .001); however, the proportion of node-positive cancers did not change with time (40% in 1988-1990, 42% in 2006-2008, P = .53). Although patients with high levels of lymph node evaluation were only slightly more likely to be node positive (adjusted odds ratio for 30-39 nodes vs 1-8 nodes, 1.11; 95% CI, 1.02-1.20), these patients experienced significantly lower hazard of death compared with those with fewer nodes evaluated (adjusted hazard ratio for 30-39 nodes vs 1-8 nodes, 0.66; 95% CI, 0.62-0.71; unadjusted 5-year mortality, 35.3%). CONCLUSION The number of lymph nodes evaluated for colon cancer has markedly increased in the past 2 decades but was not associated with an overall shift toward higher-staged cancers, questioning the upstaging mechanism as the primary basis for improved survival in patients with more lymph nodes evaluated.

Background: Resections for elderly colorectal cancer (CRC) are forecasted to grow, particularly in those beyond the age limit of screening (>80 years). However, literature on operative outcomes after CRC procedures in the oldest old is focused primarily on operative mortality. We hypothesize that older age will additionally impact operative morbidity after CRC resections in a multihospital, risk-adjusted database. Study Design: We identified 19,375 patients >40 years who underwent CRC procedures in the 2005 to 2008 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Pre-, intra-, and postoperative factors were compared by age groups. Multivariable techniques were used to assess the effects of older age on operative outcome measures, adjusting for covariates. Results: Over 20% of our cohort was older than 80 years. Of those, 17% developed major complications and 29% experienced prolonged length of stay (LOS). Older patients also experienced higher rates of 30-day operative mortality (>80 years vs. 45–55 years; 6% vs. <1%), major complications (>80 years vs. 45–55 years; 21% vs. 14%), and prolonged LOS after open (>80 years vs. 45–55 years; 37% vs. 24%) and laparoscopic procedures (>80 years vs. 45–55 years; 40.5% vs. 18%). These unadjusted comparisons persisted in multivariable analyses demonstrating that older age independently predicted worse operative outcomes after CRC procedures. Conclusions: The effects of older age extend to other important outcome measures after CRC procedures beyond operative mortality. As one of the largest multihospital studies, our study identified increased morbidity in the oldest old, a growing population. Our results should stimulate review of current policy and resource allocation.

Objective:To examine the association between older age and short-term outcomes after major oncologic resections. Summary Background Data:The effect of older age on outcomes from major cancer surgery remains conflicting because of limitations in measuring coexisting comorbidities. Given the critical role of surgery, older patients and their surgeons often question decisions regarding major cancer surgery. Methods:We identified 8781 patients who underwent elective or emergent major thoracic, abdominal, or pelvic resections for neoplasms in the 2005 to 2007 American College of Surgeons National Surgical Quality Improvement Program database. Pre, intra-, and postoperative characteristics were compared by age groups. Multivariable techniques were used to predict adjusted short-term operative outcomes. Results:Older patients were more likely to have preoperative comorbidities and to receive intraoperative blood transfusions, but at the same time have shorter operative times. Increased age was also associated with higher operative mortality (4.83% for ≥75 years vs. 1.09% for ages 40–55 years), a greater frequency of major complications, and more prolonged hospital stays—all of which persisted after multivariable adjustments. Despite its strong association with 30-day operative mortality, the impact of older age was comparable to other preoperative risk-factors predictive of short-term operative outcomes. Conclusions:The present study, which is one of the largest multihospital studies, showed that older age is independently associated with worse short-term outcomes after major oncologic resections. However, the effect of age was not prohibitively worse, and is comparable to the effects of other preoperative risk factors. These findings support the use of risk-based treatment decision-making in older patients.

PURPOSE Because adolescent and young adult (AYA) patients with cancer have experienced variable improvement in survival over the past two decades, enhancing the quality and timeliness of cancer care in this population has emerged as a priority area. To identify current trends in AYA care, we examined patterns of clinical trial participation, time to treatment, and provider characteristics in a population-based sample of AYA patients with cancer. METHODS Using the National Cancer Institute Patterns of Care Study, we used multivariate logistic regression to evaluate demographic and provider characteristics associated with clinical trial enrollment and time to treatment among 1,358 AYA patients with cancer (age 15 to 39 years) identified through the Surveillance, Epidemiology, and End Results Program. RESULTS In our study, 14% of patients age 15 to 39 years had enrolled onto a clinical trial; participation varied by type of cancer, with the highest participation in those diagnosed with acute lymphoblastic leukemia (37%) and sarcoma (32%). Multivariate analyses demonstrated that uninsured, older patients and those treated by nonpediatric oncologists were less likely to enroll onto clinical trials. Median time from pathologic confirmation to first treatment was 3 days, but this varied by race/ethnicity and cancer site. In multivariate analyses, advanced cancer stage and outpatient treatment alone were associated with longer time from pathologic confirmation to treatment. CONCLUSION Our study identified factors associated with low clinical trial participation in AYA patients with cancer. These findings support the continued need to improve access to clinical trials and innovative treatments for this population, which may ultimately translate into improved survival.

PURPOSE To examine the impact of cancer on work and education in a sample of adolescent and young adult (AYA) patients with cancer. PATIENTS AND METHODS By using the Adolescent and Young Adult Health Outcomes and Patient Experience Study (AYA HOPE)-a cohort of 463 recently diagnosed patients age 15 to 39 years with germ cell cancer, Hodgkins lymphoma, non-Hodgkins lymphoma, sarcoma, and acute lymphocytic leukemia from participating Surveillance, Epidemiology, and End Results (SEER) cancer registries-we evaluated factors associated with return to work/school after cancer diagnosis, a belief that cancer had a negative impact on plans for work/school, and reported problems with work/school after diagnosis by using descriptive statistics, χ(2) tests, and multivariate logistic regression. RESULTS More than 72% (282 of 388) of patients working or in school full-time before diagnosis had returned to full-time work or school 15 to 35 months postdiagnosis compared with 34% (14 of 41) of previously part-time workers/students, 7% (one of 14) of homemakers, and 25% (five of 20) of unemployed/disabled patients (P < .001). Among full-time workers/students before diagnosis, patients who were uninsured (odds ratio [OR], 0.21; 95% CI, 0.07 to 0.67; no insurance v employer-/school-sponsored insurance) or quit working directly after diagnosis (OR, 0.15; 95% CI, 0.06 to 0.37; quit v no change) were least likely to return. Very intensive cancer treatment and quitting work/school were associated with a belief that cancer negatively influenced plans for work/school. Finally, more than 50% of full-time workers/students reported problems with work/studies after diagnosis. CONCLUSION Although most AYA patients with cancer return to work after cancer, treatment intensity, not having insurance, and quitting work/school directly after diagnosis can influence work/educational outcomes. Future research should investigate underlying causes for these differences and best practices for effective transition of these cancer survivors to the workplace/school after treatment.

Introduction: Cancer for adolescents and young adults (AYA) differs from younger and older patients; AYA face medical challenges while navigating social and developmental transitions. Research suggests that these patients are under or inadequately served by current support services, which may affect health-related quality of life (HRQOL). Methods: We examined unmet service needs and HRQOL in the National Cancer Institute’s Adolescent and Young Adult Health Outcomes and Patient Experience (AYA HOPE) study, a population-based cohort (n = 484), age 15–39, diagnosed with cancer 6–14 months prior, in 2007–2009. Unmet service needs were psychosocial, physical, spiritual, and financial services where respondents endorsed that they needed, but did not receive, a listed service. Linear regression models tested associations between any or specific unmet service needs and HRQOL, adjusting for demographic, medical, and health insurance variables. Results: Over one-third of respondents reported at least one unmet service need. The most common were financial (16%), mental health (15%), and support group (14%) services. Adjusted models showed that having any unmet service need was associated with worse overall HRQOL, fatigue, physical, emotional, social, and school/work functioning, and mental health (p’s < 0.0001). Specific unmet services were related to particular outcomes [e.g., needing pain management was associated with worse overall HRQOL, physical and social functioning (p’s < 0.001)]. Needing mental health services had the strongest associations with worse HRQOL outcomes; needing physical/occupational therapy was most consistently associated with poorer functioning across domains. Discussion: Unmet service needs in AYAs recently diagnosed with cancer are associated with worse HRQOL. Research should examine developmentally appropriate, relevant practices to improve access to services demonstrated to adversely impact HRQOL, particularly physical therapy and mental health services.

BACKGROUND Previous literature has consistently shown worse operative outcomes at low-volume hospitals (LVH) after complex cancer surgery. Whether patient-related factors impact this association remains unknown. We hypothesize that patient-related factors contribute to receipt of complex cancer surgery at LVH. STUDY DESIGN Using the 2003-2008 National Inpatient Sample, we identified 59,841 patients who underwent cancer operations for lung, esophagus, and pancreas tumors. Logistic regression models were used to examine the impact of sociodemographic factors on receipt of complex cancer surgery at LVH. RESULTS Overall, 38.4% received their cancer surgery at LVH. A higher proportion of esophagectomies were performed at LVH (70.3%), followed by pancreatectomy (38.2%) and lung resection (33.8%). Patients who were non-white, with non-private insurance, and had more comorbidities were all more likely to receive their cancer surgery at LVH (for all, p < 0.05). Multivariate analyses continued to demonstrate that non-white race, insurance status, increased comorbidities, region, and nonelective admission predicted receipt of cancer surgery at LVH across all 3 procedures. CONCLUSIONS In this large national study, non-white race and increased comorbidities contributed to receipt of cancer surgery at LVH. Patient selection and access to high-volume hospitals are likely reasons worthy of additional investigation. This study provides additional insight into the volume-outcomes relationship. Given the demonstrated outcomes disparity between high-volume hospitals and LVH, future policy and research should encourage mechanisms for referral of patients with cancer to high-volume hospitals for their surgical care.
