In-laboratory breast specimen radiography reduces tissue block utilization and improves turnaround time of pathologic examination.

BACKGROUND: This study was performed to determine whether in-laboratory specimen radiography reduces turnaround time or block utilization in surgical pathology. METHODS: Specimens processed during a 48-day trial of an in-lab cabinet radiography device (Faxitron) were compared to a control group of specimens imaged in the mammography suite during a prior 1-year period, and to a second group of specimens not undergoing imaging of any type. RESULTS: Cases imaged in the mammography suite had longer turnaround time than cases not requiring imaging (by 1.15 days for core biopsies, and 1.73 days for mastectomies; p < 0.0001). In contrast, cases imaged in-lab had turnaround time that was no longer than unimaged cases (p > 0.05 for core biopsies, lumpectomies and mastectomies). Mastectomies imaged in-lab required submission of fewer blocks than controls not undergoing any imaging (mean reduction of 10.6 blocks). CONCLUSIONS: Availability of in-lab radiography resulted in clinically meaningful improvements in turnaround time and economically meaningful reductions in block utilization.

The use of breast-conserving surgery for women treated for breast cancer in the Department of Veterans Affairs.

BACKGROUND: Previous non-stage-adjusted research described a lower use of breast-conserving surgery (BCS) for the treatment of breast cancer in the Veterans Health Administration (VHA) facilities than in the private sector. METHODS: We combined data from the VHA Centralized Cancer Registry with administrative datasets to describe surgical treatment for locoregional breast cancer in VHA facilities from 2000 to 2006. RESULTS: When considering only procedures performed in VHA facilities, BCS rates decreased from 50.5% (53/105) in 2000 to 42.3% (n = 58/137) in 2006; however, after accounting for procedures conducted in the private sector and paid for by the VHA, BCS rates approached those experienced in breast cancer patients cared for outside the VHA. CONCLUSIONS: Based solely on procedures performed in the VHA, rates of BCS use are much lower in the VHA than in the private sector. We were able to show similar rates of BCS use when we accounted for procedures paid for by the VHA but performed at an outside facility. Further exploration and prospective analyses to examine these findings are needed.

Effectiveness of radiation for prevention of mastectomy in older breast cancer patients treated with conservative surgery.

BACKGROUND: A recent clinical trial concluded that radiation therapy (RT) does not lower the risk of mastectomy and, thus, may be omitted in older women with stage I, estrogen receptor (ER)-positive breast cancer who undergo conservative surgery (CS). However, it is not known whether this finding applies to patients outside of clinical trials. Accordingly, we used the Surveillance, Epidemiology, and End Results-Medicare observational cohort to determine the effect of RT on the risk of mastectomy among older women with stage I, ER-positive breast cancer. METHODS: The authors identified 7403 women ages 70 to 79 years who underwent CS between 1992 and 2002. Claims were used to determine RT status and to identify women who underwent mastectomy subsequent to initial treatment. The Kaplan-Meier method was used to estimate the risk of subsequent mastectomy, and Cox regression analysis was used to determine the effect of RT adjusted for clinical-pathologic covariates. RESULTS: At a median follow-up of 7.3 years, the risk of subsequent mastectomy within 10 years of diagnosis was 3.2% for patients who received RT versus 6.3% for patients who did not receive RT (P < .001). In adjusted analyses, RT was associated with a lower risk of mastectomy (hazard ratio, 0.33; 95% confidence interval, 0.22-0.48; P < .001). RT provided no benefit for patients ages 75 to 79 years without high-grade tumors who had a pathologic lymph node assessment (P = .80); however, for all other subgroups, RT was associated with an absolute reduction in risk of mastectomy that ranged from 4.3% to 9.8% at 10 years. CONCLUSIONS: Outside of a clinical trial, the receipt of RT after CS was associated with a greater likelihood of ultimate breast preservation for most older women with early breast cancer.

Breast-conserving therapy versus modified radical mastectomy: socioeconomic status determines who receives what--results from case-control study in Tianjin, China.

BACKGROUND: Despite anecdotal evidence linking socioeconomic status and choices on surgical management in breast cancer patients in China, no scientific evaluations have ever been conducted. The objective of this study was to evaluate patient factors that influence patients' treatment options between breast cancer patients receiving breast-conserving therapy (BCT) and modified radical mastectomy (MRM). METHODS: A total of 268 stage I-II breast cancer patients treated with BCT in Tianjin Cancer Hospital, from January 2005 to January 2007, were compared with 200 randomly selected breast cancer patients (controls) treated with MRM. A personal health questionnaire (PHQ) was used to assess the factors that may affect the surgical decision making. Chi-squared test and multiple logistic regressions were used to examine factors associated with BCT. RESULTS: BCT patients who were younger and were more likely to live in urban areas had medical insurance, higher levels of education and family income. Patients with medical insurance coverage were approximately six times more likely to receive BCT than patients without medical insurance after controlling for other potentially confounding factors. Similar results were also observed for family income. The observed differences cannot be explained by clinical aspects of their disease, such as tumor stage, estrogen receptor, and lymph node involvement. CONCLUSION: Breast cancer patients' socioeconomic status, rather than their clinical condition, is the predominant factor in determining whether a breast cancer patient receives BCT or not. These results provide a snapshot on how socioeconomic status influences cancer care provision in China. Future efforts should be made towards reducing discrepancies in treatment options for cancer patients caused by social class and socioeconomic status.

Re-resection rates after breast-conserving surgery as a performance indicator: introduction of a case-mix model to allow comparison between Dutch hospitals.

AIM: Re-resection rate after breast-conserving surgery (BCS) has been introduced as an indicator of quality of surgical treatment in international literature. The present study aims to develop a case-mix model for re-resection rates and to evaluate its performance in comparing results between hospitals. METHODS: Electronic records of eligible patients diagnosed with in-situ and invasive breast cancer in 2006 and 2007 were derived from 16 hospitals in the Rotterdam Cancer Registry (RCR) (n = 961). A model was built in which prognostic factors for re-resections after BCS were identified and expected re-resection rate could be assessed for hospitals based on their case mix. To illustrate the opportunities of monitoring re-resections over time, after risk adjustment for patient profile, a VLAD chart was drawn for patients in one hospital. RESULTS: In general three out of every ten women had re-surgery; in about 50% this meant an additive mastectomy. Independent prognostic factors of re-resection after multivariate analysis were histological type, sublocalisation, tumour size, lymph node involvement and multifocal disease. After correction for case mix, one hospital was performing significantly less re-resections compared to the reference hospital. On the other hand, two were performing significantly more re-resections than was expected based on their patient mix. CONCLUSIONS: Our population-based study confirms earlier reports that re-resection is frequently required after an initial breast-conserving operation. Case-mix models such as the one we constructed can be used to correct for variation between hospitals performances. VLAD charts are valuable tools to monitor quality of care within individual hospitals.

Breast conservation therapy rates are no different in medically indigent versus insured patients with early stage breast cancer.

PURPOSE: Multiple prospective, randomized studies show that breast conservation therapy (BCT) results in survival rates equal to mastectomy (Mx) for patients with early stage breast cancer (ESBC). Nevertheless, BCT remains underused in certain areas of the nation, without clearly definable reasons. Several studies have implicated socioeconomic status as one potential cause for this disparity in BCT usage. We sought to compare BCT rates in the medically indigent versus insured patients, within the same institution. METHODS: Data from 1993 to 2000, collected from the institutional tumor registry and the hospital's claims records, were analyzed for 928 patients with ESBC (Stages 0, I, and II), treated at a single medical center. The same surgeons treated both insured and indigent patients. Patients treated by BCT or Mx were compared for age, race, stage, insurance status, access to a radiation therapy center, surgeon, and year of diagnosis. RESULTS: Patient age, race, surgeon, or insurance status did not significantly affect the rate of mastectomy. Stage I patients (P < 0.001) and those treated after 1995 had higher BCT rates (54.9% in 1993-95 vs. 70.7% in 1996-2000; P < 0.001). Travel distance to a radiation therapy center had no significant impact on BCT rates, except for patients >40 miles distant. CONCLUSIONS: These data refute the hypothesis that socioeconomic status, as reflected by medical insurance, is a determinant of BCT in women with ESBC. Distance of <40 miles to a radiation therapy facility, Stage I disease, and diagnosis after 1995 were factors associated with higher BCT rates.

The use and outcomes of outpatient mastectomy in Florida.

BACKGROUND: To identify patient characteristics associated with outpatient mastectomies and their outcomes. METHODS: Patients diagnosed with breast cancer and treated with mastectomies in Florida in 1994 were identified from state discharge abstracts and the state tumor registry. The relationship between clinical/demographic characteristics and the odds of having an outpatient mastectomy was identified using multiple logistic regression. Outcomes were assessed by calculating the risk of being rehospitalized within 30 days of discharge. RESULTS: Twenty percent of mastectomies were performed on an outpatient basis. Outpatient mastectomies were more likely to be performed on women who were older, who lived in higher income communities, or who were uninsured. Health insurance type was not associated with having an outpatient mastectomy. Women undergoing outpatient mastectomy were more likely to be readmitted within 30 days of discharge; however, the excess risk was very small (0.7%). CONCLUSIONS: The risks from outpatient mastectomy are small. Ongoing monitoring of outcomes and assessment of patient satisfaction are needed.

[Initial experiences with shorter hospital stays after primary surgery for breast carcinoma]. / Eerste ervaringen met opnameduurverkorting na primaire chirurgie wegens mammacarcinoom.

OBJECTIVE: To describe some personal, medical and financial consequences of moving up the discharge of patients from hospital after an operation because of breast carcinoma. DESIGN: Descriptive. SETTING: Department of Oncological Surgery, Medical Centre, Leiden University, Leiden, the Netherlands. METHOD: Thirty-five patients with breast cancer were operated during the period March to August 1997. Thirteen patients of this group were discharged sooner after operation, with the drain still in situ; the other 22 remained in hospital until after removal of the drain. Medical and financial consequences were investigated. RESULTS: The patient characteristics of the two groups were similar. In the group discharged earlier, the number of postoperative days in hospital on average was 4.5 days smaller. The number of postoperative complications in the two groups were similar; development of seroma after removal of the drain occurred less frequently in the group discharged earlier. The financial savings amounted to an average of Dfl. 2497.-per patient. The patients discharged earlier were very satisfied. CONCLUSION: The orientative study suggests that moving up discharge after a breast cancer operation is a policy that is safe, financially advantageous and satisfactory to the patients.

Variation in the use of breast-conserving therapy for Medicare beneficiaries in Virginia: clinical, geographic, and hospital characteristics.

BACKGROUND: Treatment for early-stage breast cancer has evolved significantly in recent years. Breast-conserving therapy (BCT) has been shown to offer equivalent survival compared to traditional mastectomy. However, there is marked variation in the performance of BCT which may not reflect clinical appropriateness or patient preference. Little is known about the factors related to variation in BCT performance in older women with early-stage breast cancer. METHODS: Retrospective claims analysis of 1,512 Medicare patients using part-A data for the years 1992 to 1993, with additional explicit chart review. A clinical algorithm was developed to categorize patients according to their candidacy for BCT and compare this to their treatment. Demographic, clinical, and geographic variables were included in the model. RESULTS: The overall BCT rate in Virginia was 20%, with marked variation among providers of all types. BCT rates ranged from 0% to 44% among hospitals caring for more than 12 cases per year. Twenty-six percent of patients considered good candidates for BCT by current guidelines received this option. Large urban hospitals had significantly higher rates of BCT than smaller hospitals, regardless of the presence of radiation oncology capability. Distance from radiation oncology facilities was a factor in low BCT rates of rural populations, but low BCT rates also were present even in facilities with access to radiation oncology services. CONCLUSIONS: These data present a detailed analysis of the patterns of BCT for Virginia Medicare beneficiaries with early-stage breast cancer. Clinical contraindications to BCT for confirmed early-stage disease were uncommon. Despite similar patient profiles and hospital-reported range of cancer services, marked variation in BCT rates exists. A large number of patients chose traditional mastectomy over BCT due to fears of radiation, but few received radiation oncology consultation. BCT rates were highest in hospitals with radiation oncology facilities on grounds; hospitals with facilities nearby had rates similar to those without access to radiation facilities. Patient preferences are documented poorly. This study provides further evidence that many women are receiving BCT in patterns that may not reflect clinical appropriateness for BCT nor access to necessary facilities.

Surgical management of breast cancer in Australian women in 1993: analysis of Medicare statistics.

OBJECTIVE: To examine patterns of surgical management of breast cancer among Australian women. DESIGN: Retrospective survey of Medicare records (a national dataset of all services rendered on a "fee-for-service" basis for which a Medicare benefit has been paid). PATIENTS: All Australian women (4683) who underwent surgery consistent with being for breast cancer in 1993 and for which Medicare benefits were paid. MAIN OUTCOME MEASURES: Proportions of women undergoing different forms of mastectomy, breast-conserving surgery and axillary surgery by patient age and State and region (urban or rural) of residence. RESULTS: Modified radical mastectomy was the most common surgery, performed in 2097 of the 4683 women (44.8%), while 1868 (39.9%) had breast-conserving surgery. Frequency of breast conservation decreased significantly with age and varied significantly between States and region of residence. It ranged from 34% in Western Australia to 49% in South Australia and the Northern Territory, and from 34% among rural women to 42% among urban women. Axillary surgery was recorded for 83% of all women studied. CONCLUSIONS: There was substantial geographical variation in patterns of surgical management for breast cancer. The tendency for rural women to undergo mastectomy rather than breast-conserving surgery may reflect the relative lack of access to postoperative radiotherapy. We are unable to explain the variation between States.

Breast cancer treatment choice and mastectomy length of stay: a comparison of HMO and other privately insured women.

This study uses hospital discharge abstract data from five states (Massachusetts, New York, New Jersey, Maryland, and California) for two years (1988 and 1991) to investigate whether enrollment in an HMO affects nonelderly breast cancer patients' treatment choice (breast-conserving surgery or mastectomy) and hospital length of stay for women who have a mastectomy. Since HMO insurance creates financial incentives that differ from other types of insurance coverage, it is important to assess whether the type of insurance coverage affects the care received by breast cancer patients. Although the results vary from state to state, they suggest that HMO enrollees are less likely to receive breast-conserving surgery (relative odds =.93). However, an unambiguous interpretation of this findings requires better data on patients' opportunity costs and preferences, which also may vary with type of insurance coverage. Among women who had a mastectomy, HMO enrollment was generally associated with a 4.5% shorter average length of stay and a greater likelihood of a short stay (one or two days, relative odds = 1.21-1.29). A much higher proportion of mastectomy patients in California than in other states had a short stay. Follow-up of these women may indicate whether short stays lead to adverse long-term health effects.

[Breast cancer treated at the oncologic department, University Hospital in Tromsø 1986-94]. / Brystkreft behandlet ved Kreftavdelingen, Regionsykehuset i Tromsø 1986-94.

In the period 1986 to 94, 173 women who had had a lumpectomy or a mastectomy were treated with radiotherapy at the University Hospital of Tromsø. The median diagnostic delay was 2.4 months (range 0-98.6 months). Three out of four patients were operated on within two weeks of the diagnosis being made. About two thirds experienced a delay of more than six weeks from the operation to the start of radiotherapy treatment. The five-year overall survival rate in the mastectomy and postoperative radiotherapy group was 67%. Patients with estrogen receptor positive tumours had a better prognosis. Only 5% and 7% of all patients in our region in stages I and II had breast conserving surgery (BCS) during the study period (66 patients). The five-year overall survival rate in the BCS group was 77%. BCS raised the cost per patient by about 3,000 GBP compared to modified radical mastectomy (MRM). The cost per QALY using BCS as against MRM was about 12,000 GBP. We conclude that MRM should not be used instead of BCS merely for economical reasons.
