Trends and clinical implications of preoperative breast MRI in Medicare beneficiaries with breast cancer.

While there has been increasing interest in the use of preoperative breast magnetic resonance imaging (MRI) for women with breast cancer, little is known about trends in MRI use, or the association of MRI with surgical approach among older women. Using the Surveillance, Epidemiology and End Results-Medicare database, we identified a cohort of women diagnosed with breast cancer from 2000 to 2009 who underwent surgery. We used Medicare claims to identify preoperative breast MRI and surgical approach. We evaluated temporal trends in MRI use according to age and type of surgery, and identified factors associated with MRI. We assessed the association between MRI and surgical approach: breast-conserving surgery (BCS) versus mastectomy, bilateral versus unilateral mastectomy, and use of contralateral prophylactic mastectomy. Among the 72,461 women in our cohort, 10.1 % underwent breast MRI. Preoperative MRI use increased from 0.8 % in 2000-2001 to 25.2 % in 2008-2009 (p < 0.001). Overall, 43.3 % received mastectomy and 56.7 % received BCS. After adjustment for clinical and demographic factors, MRI was associated with an increased likelihood of having a mastectomy compared to BCS (adjusted odds ratio = 1.21, 95 % CI 1.14-1.28). Among women who underwent mastectomy, MRI was significantly associated with an increased likelihood of having bilateral cancer diagnosed (9.7 %) and undergoing bilateral mastectomy (12.5 %) compared to women without MRI (3.7 and 4.1 %, respectively, p < 0.001 for both). In conclusion, the use of preoperative breast MRI has increased substantially among older women with breast cancer and is associated with an increased likelihood of being diagnosed with bilateral cancer, and more invasive surgery.

Incidental appendectomy--standard or unnecessary additional trauma in surgery for colorectal cancer? A retrospective analysis of histological findings in 380 specimens.

BACKGROUND: Incidental appendectomy is a frequent but non-standard procedure during surgery for colorectal cancer. Incidental appendectomy during colorectal resections is performed at the discretion of the operating surgeon. METHOD: This retrospective study used data from 1352 consecutive patients who underwent surgery for colorectal cancer between 1993 and 2009 at the Medical University of Vienna. The authors evaluated histopathological results of appendices removed incidentally. In addition, complications and costs of the additional intervention were analyzed. RESULTS: Appendectomy had been performed in 314 (23.22%) patients because of appendicitis. Incidental appendectomy had been performed in 380 (28.11%) patients: 86 (22.63%) had a histologically completely normal appendix, a pathologic alteration was found in 289 (76.05%) and a neoplasm was found in seven (1.84%). No complications occurred from the additional surgical procedure. The costs and time effort were negligible. CONCLUSION: Incidental appendectomy is a safe procedure and can be integrated into surgery for colorectal carcinoma to avoid future complications. Pathological findings of the appendix, including neoplasm, are frequent but the clinical relevance remains questionable.

Results of the Zometa cost-utility model for the german healthcare system based on the results of the ABCSG-12 study.

BACKGROUND: The ABCSG-12 trial investigated the efficacy of gonadotropin-releasing hormone (GnRH)analogs in combination with tamoxifen or anastrozole + or - zoledronic acid (4 mg, q6m for 3 years) in 1,803 premenopausal women with hormone receptor-positive (HR+) breast cancer. After 48 months of follow-up, there was a 36% improvement in the disease-free survival (DFS) (recurrence-free survival 35%) using zoledronic acid. Based on these data, the costutility of zoledronic acid was calculated for the German healthcare system. MATERIALS AND METHODS: Costs of surveillance, adverse effects, recurrence, contralateral breast cancer, metastasis, and end-of-life care were determined based on the Einheitlicher Bewertungsmabetastab (EBM 2009) and the diagnosis-related groups (DRG) system. Utilities were surveyed with a questionnaire (n = 95). Estimation of the cost-utility was made by calculating the incremental costeffectiveness ratio (ICER) per quality-adjusted life year (QALY), using a Markov model. RESULTS: Including zoledronic acid as adjuvant therapy for 3 years resulted in total costs of euro 2,262. The use of zoledronic acid is dominant when clinical efficacy and quality of life are taken into consideration (- euro 45.83/QALY) (95% confidence interval (CI) - euro 1,838 to E 2,375; 0.02-0.41 QALY). The sensitivity analyses present with a probability of 90% that the cost per QALY gained are

Time-Driven Activity-Based Costing Comparison of Stereotactic Radiosurgery to Multiple Brain Lesions Using Single-Isocenter Versus Multiple-Isocenter Technique.

PURPOSE: Stereotactic radiosurgery (SRS) historically has been used to treat multiple brain lesions using a multiple-isocenter technique-frequently associated with significant complexity in treatment planning and long treatment times. Recently, given innovations in planning algorithms, patients with multiple brain lesions may now be treated with a single-isocenter technique using fewer total arcs and less time spent during image guidance (though with stricter image guided radiation therapy tolerances). This study used time-driven activity-based costing to determine the difference in cost to a provider for delivering SRS to multiple brain lesions using single-isocenter versus multiple-isocenter techniques. METHODS AND MATERIALS: Process maps, consisting of discrete steps, were created for each phase of the SRS care cycle and were based on interviews with department personnel. Actual treatment times (including image guidance) were extracted from treatment record and verify software. Additional sources of data to determine costs included salary/benefit data of personnel and average list price/maintenance costs for equipment. RESULTS: Data were collected for 22 patients who underwent single-isocenter SRS (mean lesions treated, 5.2; mean treatment time, 30.2 minutes) and 51 patients who underwent multiple-isocenter SRS (mean lesions treated, 4.4; mean treatment time, 75.2 minutes). Treatment time for multiple-isocenter SRS varied substantially with increasing number of lesions (11.8 minutes/lesion; P < .001), but to a much lesser degree in single-isocenter SRS (1.8 minutes/lesion; P = .029). The resulting cost savings from single-isocenter SRS based on number of lesions treated ranged from $296 to $3878 for 2 to 10 lesions treated. The 2-mm planning treatment volume margin used with single-isocenter SRS resulted in a mean 43% increase of total volume treated compared with a 1-mm planning treatment volume expansion. CONCLUSIONS: In a comparison of time-driven activity-based costing assessment of single-isocenter versus multiple-isocenter SRS for multiple brain lesions, single-isocenter SRS appears to save time and resources for as few as 2 lesions, with incremental benefits for additional lesions treated.

Cost-effectiveness of scan-directed parathyroidectomy.

BACKGROUND: Concordant parathyroid localization with sestamibi and ultrasound scans allows minimally invasive parathyroidectomy (MIP) to be performed in patients with non-familial primary hyperparathyroidism (PHPT). AIM: To investigate the financial implications of scan-directed parathyroid surgery. METHODS: Analysis of hospital records for a cohort of consecutive unselected patients treated in a tertiary referral centre. RESULTS: Two hundred patients (138F:62M, age 18-91years) were operated for non-familial PHPT between Jan 2003 and Oct 2007. MIP was performed in 129 patients, with a mean operative time was 35 +/- 18min. Some 75 patients were discharged the same day and the others had a total of 72 in-patient days. Bilateral neck exploration (BNE) was performed in 71 patients with negative/non-concordant scans. Mean operative time was 58 +/- 25min. Only nine patients were discharged the same day and a total of 93 in-patient days were used ( approximately 1.3days/patient). The estimated total costs incurred were pound215,035 ( approximately 290,000). These costs would have been covered by the National Tariff ( pound2,170 per parathyroidectomy) but were higher than those possibly incurred if all 200 patients would have undergone BNE without any radiological investigations ( pound166,000 approximately 224,100euro). CONCLUSION: Shorter operative time and day-case admission for MIP generate costs savings that compensate only partially for the additional costs associated with parathyroid imaging studies.

Multiplicity of skin cancers in Queensland and their cost burden to government and patients.

OBJECTIVE: To determine the cost burden to government and patients for individuals with multiple skin cancers. METHODS: We used self-reported baseline data on socio-demographics, phenotype and sun exposure behaviours from participants in the QSkin Sun and Health Study with at least one histopathologically confirmed keratinocyte cancer or melanoma (n=5,673). Linkage to Australian Medicare data (2011-2014) provided resource data and government and out-of-pocket patient costs. Generalised linear models examined costs by frequency of skin cancer groups separately for melanoma and keratinocyte cancer. RESULTS: Over three years, 539 participants were diagnosed with melanoma (11% had ≥2 melanomas) and 5,134 participants were treated for keratinocyte cancers (10% had ≥6). Median Medicare costs per person were $1,325 (maximum $6,117) for ≥2 melanomas and $2,126 (maximum $54,618) for ≥6 keratinocyte cancers. Increased costs were associated with private health insurance. CONCLUSIONS: Individuals who are multiply affected by skin cancers are relatively common and the accompanying individual and government cost burden can be substantial. These findings support skin cancer being classified as a chronic disease. Implications for public health: Over time, the economic burden for skin cancer for individuals and health providers is high and investment in prevention remains important from an economic viewpoint.

Direct inpatient costs and influencing factors for patients with rectal cancer with low anterior resection: a retrospective observational study at a three-tertiary hospital in Beijing, China.

OBJECTIVES: The aim of the study was to investigate the direct inpatient cost and analyse influencing factors for patients with rectal cancer with low anterior resection in Beijing, China. DESIGN: A retrospective observational study. SETTING: The study was conducted at a three-tertiary oncology institution. PARTICIPANTS: A total of 448 patients who underwent low anterior resection and were diagnosed with rectal cancer from January 2015 to December 2016 at Peking University Cancer Hospital were retrospectively identified. Demographic, clinical and cost data were determined. RESULTS: The median inpatient cost wasï¿¥89 064, with a wide range (ï¿¥46 711-ï¿¥191 329) due to considerable differences in consumables. The material cost accounted for 52.19% and was the highest among all the cost components. Colostomy (OR 4.17; 95% CI 1.79 to 9.71), complications of hypertension (OR 5.30; 95% CI 1.94 to 14.42) and combined with other tumours (OR 2.92; 95% CI 1.12 to 7.60) were risk factors for higher cost, while clinical pathway (OR 0.10; 95% CI 0.03 to 0.35), real-time settlement (OR 0.26; 95% CI 0.10 to 0.68) and combined with cardiovascular disease (OR 0.09; 95% CI 0.02 to 0.52) were protective determinants. CONCLUSIONS: This approach is an effective way to relieve the economic burden of patients with cancer by promoting the clinical pathway, optimising the payment scheme and controlling the complication. Further research focused on the full-cost investigation in different stages of rectal cancer based on a longitudinal design is necessary.

Combined laparoscopic-assisted nephrectomy and complete mesocolic excision for synchronous renal and colon cancers.

Cancers of the colon and kidney are common malignancies, however, the occurrence of primary synchronous neoplasms of these two organs is uncommon. To the best of our knowledge, this is the first case report of a laparoscopic radical left nephrectomy and extended right complete mesocolic excision (CME) for a patient with synchronous renal and colon cancers. While a radical nephrectomy has long been the standard of care for a renal malignancy, CME has only recently been used. Combined surgeries provide the patient with various benefits such as decreased hospital stay, less postoperative pain and morbidity, early return to work and better cosmoses.

Is routine triple endoscopy cost-effective in head and neck cancer?

The multicentric occurrence of tumors of the upper aerodigestive tract has been well described, with an incidence ranging from 5 to 16 percent. Detection of a synchronous primary tumor at the time of initial work-up is crucial both for management and final outcome. However, there is a diversity of opinions regarding the extent of the work-up to search for a second primary tumor. Some investigators consider routine panendoscopy to be essential for every patient with a head and neck primary tumor. Routine esophagoscopy and bronchoscopy with bronchial washings in the absence of specific symptoms appear to have minimal benefit and high cost. In our study of 140 consecutive patients with primary squamous cell carcinoma of the head and neck seen over a period of 3 years, detailed history, thorough head and neck examination, routine chest radiograph, and barium swallow when indicated were sufficient to identify 18 patients (13 percent) with a second primary tumor in the upper aerodigestive tract. The synchronous tumors of eight patients were in the head and neck area, seven patients had carcinoma of the lung, and three patients had a second primary in the esophagus. Two patients had three synchronous primaries. Follow-up of these patients ranged from 1 to 4 years. Panendoscopy with cytologic washings was performed routinely. We questioned the cost-effectiveness of routine triscopy in every patient with head and neck cancer.

Socioeconomic impact of modern multidisciplinary management of retinoblastoma.

OBJECTIVE: Our objective for this study was to examine the impact of the modern management of intraocular retinoblastoma on the patient and the family. METHODS: This study comprises a retrospective, noncomparative case series of 25 consecutive patients with multifocal, intraocular retinoblastoma that was treated with primary systemic chemotherapy. Medical charts were reviewed, and the following data were extracted: patients' age and gender, laterality of disease, and Reese-Ellsworth classification of each eye as well as the number of central venous lines placed, cycles of chemotherapy received, outpatient appointments, examinations under anesthesia, focal therapies administered, computed tomography/MRI, radiation treatments, anesthetic procedures administered, and miles traveled. RESULTS: Twenty patients with bilateral and 5 with unilateral intraocular retinoblastoma (median age: 9.3 months) had 895 outpatient appointments and underwent 698 examinations under anesthesia with 230 focal therapies, 347 days of radiotherapy, 226 computed tomography scans/MRIs, and 38 central venous line placements. A total of 1272 anesthetic procedures (median: 50) were performed with no major complication. In all, patients traveled 822312 miles (median: 22214 miles) to receive their care. The median follow-up was 82 months. CONCLUSIONS: Successful retinoblastoma management requires close surveillance, aggressive consolidation, and numerous anesthetic procedures, all of which the patients and the families must endure. There is a significant impact on the patient, the family, and hospital resources.
