Cost-effectiveness of contralateral prophylactic mastectomy for prevention of contralateral breast cancer.

BACKGROUND: A growing number of women with sporadic unilateral, early-stage breast cancers are undergoing ipsilateral therapeutic mastectomy with contralateral prophylactic mastectomy (CPM) to prevent the development of new cancers in the contralateral breast. METHODS: A decision-tree using TreeAge Pro 2012 software was used to model the costs and effects of CPM versus unilateral mastectomy (UM) in women younger than 50 years of age with sporadic unilateral, early stage breast cancers. Cost estimates were obtained from the Medicare Fee Schedule and the Healthcare Utilization Project. Probability estimates were obtained from the literature. Outcome effects were measured by incremental cost per quality-adjusted life year (QALY) gained. A 10-year risk period for contralateral breast cancer (CBC), a lifetime time horizon, and a societal perspective were used. RESULTS: Treatment with CPM results in 0.2 QALYs less than UM and $279 less in costs during a 10-year risk period and lifetime follow-up. The resulting incremental cost effectiveness ratio (ICER) is a savings of $1397 per QALY lost. The ICER is sensitive to the rate and method of postmastectomy reconstruction and the cost of radiologic surveillance after UM. CONCLUSIONS: CPM is cost-saving for the prevention of CBC in women younger than 50 years of age with sporadic, unilateral, early-stage breast cancers, but also reduces resulting health. The savings for health lost are insufficient to be considered cost-effective at this time.

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.

Cost-effectiveness of contralateral prophylactic mastectomy versus routine surveillance in patients with unilateral breast cancer.

PURPOSE: Contralateral prophylactic mastectomy (CPM) rates in women with unilateral breast cancer are increasing despite controversy regarding survival advantage. Current scrutiny of the medical costs led us to evaluate the cost-effectiveness of CPM versus routine surveillance as an alternative contralateral breast cancer (CBC) risk management strategy. METHODS: Using a Markov model, we simulated patients with breast cancer from mastectomy to death. Model parameters were gathered from published literature or national databases. Base-case analysis focused on patients with average-risk breast cancer, 45 years of age at treatment. Outcomes were valued in quality-adjusted life-years (QALYs). Patients' age, risk level of breast cancer, and quality of life (QOL) were varied to assess their impact on results. RESULTS: Mean costs of treatment for women age 45 years are comparable: $36,594 for the CPM and $35,182 for surveillance. CPM provides 21.22 mean QALYs compared with 20.93 for surveillance, resulting in an incremental cost-effectiveness ratio (ICER) of $4,869/QALY gained for CPM. To prevent one CBC, six CPMs would be needed. CPM is no longer cost-effective for patients older than 70 years (ICER $62,750/QALY). For BRCA-positive patients, CPM is clearly cost-effective, providing more QALYs while being less costly. In non-BRCA patients, cost-effectiveness of CPM is highly dependent on assumptions regarding QOL for CPM versus surveillance strategy. CONCLUSION: CPM is cost-effective compared with surveillance for patients with breast cancer who are younger than 70 years. Results are sensitive to BRCA-positive status and assumptions of QOL differences between CPM and surveillance patients. This highlights the importance of tailoring treatment for individual patients.

Costs of treatment for elderly women with early-stage breast cancer in fee-for-service settings.

PURPOSE: This study provides population-based estimates of the treatment costs for elderly women with early-stage breast cancer, with emphasis on costs of modified radical mastectomy (MRM) compared with breast-conserving surgery (BCS) and radiation therapy (RT). PATIENTS AND METHODS: Women with breast cancer from the Surveillance, Epidemiology, and End Results cancer registries were linked with their Medicare claims, 1990 through 1998. Each claim was assigned to an initial, continuing, or terminal care phase after a cancer diagnosis. Mean monthly phase-specific costs were determined for all health care and for treatment related only to cancer. Cumulative long-term costs of care that accrue during a women's remaining lifetime were calculated by treatment group. RESULTS: Initial care costs for the 6 months after diagnosis for women who underwent BCS with RT were approximately $450 per month higher than for women with MRM. During the continuing-care phase, costs for women undergoing BCS with RT were significantly less expensive than for MRM cases. The two groups had similar costs in the terminal-care phase. Assuming the same survival distributions, long-term costs for women undergoing BCS with RT were not statistically different than for women undergoing MRM. CONCLUSION: Although mastectomy was less costly in the initial phase, the lifetime costs of BCS with RT and mastectomy were equivalent. Thus, women's preferences, resources to cover out-of-pocket costs, and life situations should be the major factors addressed in shared decision making about treatment options.

Cost comparison of mastectomy versus breast-conserving therapy for early-stage breast cancer.

BACKGROUND: Choice of treatment for early-stage breast cancer depends on many factors, including the size and stage of the cancer, the woman's age, comorbid conditions, and perhaps the costs of treatment. We compared the costs of all medical care for women with early-stage breast cancer cases treated by breast-conserving therapy (BCT) or mastectomy. METHODS: A total of 1675 women 35 years old or older with incident early-stage breast cancer were identified in a large regional nonprofit health maintenance organization in the period 1990 through 1997. The women were treated with mastectomy only (n = 183), mastectomy with adjuvant hormonal therapy or chemotherapy (n = 417), BCT with radiation therapy (n = 405), or BCT with radiation therapy and adjuvant hormonal therapy or chemotherapy (n = 670). The costs of all medical care for the period 1990 through 1998 were computed for each woman, and monthly costs were analyzed by treatment, adjusting for age and cancer stage. All statistical tests were two-sided. RESULTS: At 6 months after diagnosis, the mean total medical care costs for the four groups differed statistically significantly (P:<.001), with BCT being more expensive than mastectomy. The adjusted mean costs were $12 987, $14 309, $14 963, and $15 779 for mastectomy alone, mastectomy with adjuvant therapy, BCT plus radiation therapy, and BCT plus radiation therapy with adjuvant therapy, respectively. At 1 year, the difference in costs was still statistically significant (P:<.001), but costs were influenced more by the use of adjuvant therapy than by type of surgery. The 1-year adjusted mean costs were $16 704, $18 856, $17 344, and $19 081, respectively, for the four groups. By 5 years, BCT was less expensive than mastectomy (P:<.001), with 5-year adjusted mean costs of $41 930, $45 670, $35 787, and $39 926, respectively. Costs also varied by age, with women under 65 years having higher treatment costs than older women. CONCLUSIONS: BCT may have higher short-term costs but lower long-term costs than mastectomy.

[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.

Variations in charges for two major breast cancer surgeries, U.S., 1996.

In 1996, the total in-hospital charges for the primary treatment of women with breast cancer with a modified radical mastectomy averaged $10,000 throughout the United States. The total charge (hospital plus physician's fees) varied by 95% between the high charge reported in New York ($12,690) and the low charge in Michigan ($6,510). The hospital portion of the bill averaged 65% of the total and ranged from 51% in New York to 74% in Virginia. The average length of stay for these women was 2.39 days and ranged from 3.18 days in New York to 1.69 and 1.66 days in Washington and Arizona, respectively. The average charge for a partial mastectomy was $8,760, with notable variations between states. The Texas total charge was the highest ($12,890, some 47% above the US norm) and more than twice the low charge in Ohio ($6,080, 31% below the US average). The physicians' charges averaged $3,330 for the country as a whole and accounted for 38% of the bill. This proportion ranged from 46% of the total in New York to 70% in Indiana and Colorado. The average length of hospitalization for a partial mastectomy was 1.84 days. On average, women remained in the hospital for the longest time in New Jersey (2.78 days) and for the shortest time in Oregon and Massachusetts (1.40 days and 1.45 days, respectively).

Lumpectomy or mastectomy? Is breast conserving surgery too expensive?

In the last decade, breast cancer patients have enjoyed an increase in breast conserving surgery (BCS). At present, modified radical mastectomy (MRM) and BCS offers equal expectations of survival. During the last few years, however, a drop in the frequency of BCS has been reported by several authors. Is this new trend due to economic concerns? To clarify the costs of breast cancer therapy (stage I and II), we review the literature and include a cost-utility and a cost-minimisation analysis comparing MRM and BCS. The treatment cost (per patient) of BCS and MRM in Norway was calculated at $9,564 and $5,596, respectively. Employing a quality of life gain in BCS of 0.03 (0-1 scale) and a 5% discount rate, the cost per QALY in BCS compared to MRM was $20,508. In cost-minimising analysis, BCS and mastectomy followed by reconstructive surgery had a cost of $10,748 and $8,538, respectively. This indicates that BCS remains within reasonable cost and should not be displaced by mastectomy on economic grounds.

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.

Early drain removal following modified radical mastectomy: a randomized trial.

The dilemma of increasing costs of medical care and shrinking health budgets has stimulated attempts to implement stricter control on expenditure without affecting the quality of care. This study shows that in patients with operable breast cancer, a policy of early discharge after a mastectomy did not have deleterious effects on wound healing and was well accepted by patients. In a randomized trial, drains were removed after either 3 or 6 days postmastectomy, and in both groups of patients there was no difference between the mean volumes of seromas aspirated or the number of aspirations and return visits to the hospital. This suggests that a policy of early discharge is safe, acceptable, economical, and may improve bed utilization.

Modified radical mastectomies: average charges, 1988.

Average charge of $6,160 was billed to Metropolitan Life Insurance Company for 807 modified radical mastectomies during 1988. The average physicians' fees were $2,090. Length of hospital stay averaged 4.3 days across the country. The charges varied by as much as 92 percent between states. Among the 19 states included in the study, New York and California reported the highest average total charges ($7,870 and $7,290) and Iowa and Minnesota reported the lowest average charges ($4,100 and $4,620). On average, hospital expense comprised 66 percent of the total charges and ancillary fees accounted for almost three-fourths of the hospital bill.
