Cost-effectiveness analysis of tumor molecular classification in high-risk early-stage endometrial cancer.

PURPOSE: Tumor molecular analyses in endometrial cancer (EC) includes 4 distinct subtypes: (1) POLE-mutated, (2) mismatch repair protein (MMR) deficient, (3) p53 mutant, and (4) no specific molecular profile. Recently, a sub-analysis of PORTEC-3 demonstrated notable differences in treatment response between molecular classification (MC) groups. Cost of testing is one barrier to widespread adoption of MC. Therefore, we sought to determine the cost-effectiveness of MC in patients with stage I and II high-risk EC. METHODS: A Markov decision model was developed to compare tumor molecular classification (TMC) vs. no testing (NT). A healthcare payor's perspective and 5-year time horizon were used. Base case data were abstracted from PORTEC-3 and the molecular sub-analysis. Cost and utility data were derived from public databases, peer-reviewed literature, and expert input. Strategies were compared using the incremental cost-effectiveness ratio (ICER) with effectiveness in quality-adjusted life years (QALYs) and evaluated with a willingness-to-pay threshold of $100,000 per QALY gained. Sensitivity analyses were performed to test model robustness. RESULTS: When compared to NT, TMC was cost effective with an ICER of $25,578 per QALY gained; incremental cost was $1780 and incremental effectiveness was 0.070 QALYs. In one-way sensitivity analyses, results were most sensitive to the cost of POLE testing, but TMC remained cost-effective over all parameter ranges. CONCLUSIONS: TMC in early-stage high-risk EC is cost-effective, and the model results were robust over a range of parameters. Given that MC can be used to guide adjuvant treatment decisions, these findings support adoption of TMC into routine practice.

Patterns of Medical Care Cost by Service Type for Patients With Recurrent and De Novo Advanced Cancer.

OBJECTIVES: There is limited knowledge about the cost patterns of patients who receive a diagnosis of de novo and recurrent advanced cancers in the United States. METHODS: Data on patients who received a diagnosis of de novo stage IV or recurrent breast, colorectal, or lung cancer between 2000 and 2012 from 3 integrated health systems were used to estimate average annual costs for total, ambulatory, inpatient, medication, and other services during (1) 12 months preceding de novo or recurrent diagnosis (preindex) and (2) diagnosis month through 11 months after (postindex), from the payer perspective. Generalized linear regression models estimated costs adjusting for patient and clinical factors. RESULTS: Patients who developed a recurrence <1 year after their initial cancer diagnosis had significantly higher total costs in the preindex period than those with recurrence ≥1 year after initial diagnosis and those with de novo stage IV disease across all cancers (all P < .05). Patients with de novo stage IV breast and colorectal cancer had significantly higher total costs in the postindex period than patients with cancer recurrent in <1 year and ≥1 year (all P < .05), respectively. Patients in de novo stage IV and those with recurrence in ≥1 year experienced significantly higher postindex costs than the preindex period (all P < .001). CONCLUSIONS: Our findings reveal distinct cost patterns between patients with de novo stage IV, recurrent <1-year, and recurrent ≥1-year cancer, suggesting unique care trajectories that may influence resource use and planning. Future cost studies among patients with advanced cancer should account for de novo versus recurrent diagnoses and timing of recurrence to obtain estimates that accurately reflect these care pattern complexities.

Cost-effectiveness of radioguided occult lesion localization using 125I seeds versus hookwire localization before breast-conserving surgery for non-palpable breast cancer.

BACKGROUND: The aim was to determine the cost-effectiveness of radioguided occult lesion localization using 125I-labelled seeds (125I seeds) versus hookwire localization in terms of incremental cost per reoperation avoided for women with non-palpable breast cancer undergoing breast-conserving surgery. METHODS: This study was based on a multicentre RCT with eight study sites comprising seven public hospitals and one private hospital. An Australian public health system perspective was taken. The primary effectiveness outcome for this study was reoperations avoided. Cost-effectiveness was expressed as an incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were used to explore uncertainty. The willingness to pay (additional cost of localization using 125I seeds justified by reoperation cost avoided) was set at the weighted, top-down cost of reoperation. Costs were in 2019 Australian dollars ($1 was equivalent to €0.62). RESULTS: The reoperation rate was 13.9 (95 per cent confidence interval 10.7 to 18.0) per cent for the 125I seed group and 18.9 (14.8 to 23.8) per cent for the hookwire localization group. The ICER for 125I seed versus hookwire localization was $4474 per reoperation averted. The results were most sensitive to uncertainty around the probability of reoperation. Accounting for transition probability and cost uncertainty for 125I seed localization, there was a 77 per cent probability that using 125I seeds would be cost-effective, with a willingness to pay of $7693 per reoperation averted. CONCLUSION: Radioguided occult lesion localization using 125I seeds is likely to be cost-effective, because the marginal (additional) cost compared with hookwire localization is less than the cost of reoperations avoided.

Has the Affordable Care Act Been Associated with Increased Insurance Coverage and Early-stage Diagnoses of Bone and Soft-tissue Sarcomas in Adults?

BACKGROUND: Treatment of bone and soft-tissue sarcomas can be costly, and therefore, it is not surprising that insurance status of patients is a prognostic factor in determining overall survival. Furthermore, uninsured individuals with suspected bone and/or soft-tissue masses routinely encounter difficulty in obtaining access to basic healthcare (such as office visits, radiology scans), and therefore are more likely to be diagnosed with later stages at presentation. The Patient Protection and Affordable Care Act (ACA) mandate of 2010 aimed to increase access to care for uninsured individuals by launching initiatives, such as expanding Medicaid eligibility, subsidizing private insurance, and developing statewide mandates requiring individuals to have a prescribed minimum level of health insurance. Although prior reports have demonstrated that the ACA increased both coverage and the proportion of early-stage diagnoses among patients with common cancers (including breast, colon, prostate, and lung), it is unknown whether similar improvements have occurred for patients with bone and soft-tissue sarcomas. Understanding changes in insurance coverages and stage at diagnosis of patients with bone and soft-tissue sarcomas would be paramount in establishing policies that will ensure orthopaedic cancer care is made equitable and accessible to all. QUESTIONS/PURPOSES: (1) Has the introduction of the ACA been associated with changes in insurance coverage for adult patients with newly diagnosed bone and soft-tissue sarcomas? (2) Did the introduction of health reforms under the ACA lead to an increased proportion of sarcoma diagnoses occurring at earlier disease stages? METHODS: The 2007 to 2015 Surveillance, Epidemiology and End Results database was queried using International Classification of Diseases for Oncology codes for primary malignant bone tumors of the upper and lower extremity (C40.0 to C40.3), unspecified or other overlapping bone, articular cartilage, and joint and/or ribs, sternum, or clavicle (C40.8 to C40.9, C41.3, and C41.8 to C41.9), vertebral column (C41.2), pelvis (C41.4, C41.8, and C41.9), and soft-tissue sarcomas of the upper or lower extremity and/or pelvis (C49.1, C49.2, and C49.5). A total of 15,287 patients with newly diagnosed cancers were included, of which 3647 (24%) were malignant bone tumors and 11,640 (76%) were soft-tissue sarcomas. The study sample was divided into three cohorts according to specified time periods: pre-ACA from 2007 to 2010 (6537 patients), pre-Medicaid expansion from 2011 to 2013 (5076 patients), and post-Medicaid expansion from 2014 to 2015 (3674 patients). The Pearson chi square tests were used to assess for changes in the proportion of Medicaid and uninsured patients across the specified time periods: pre-ACA, pre-expansion and post-expansion. A differences-in-differences analysis was also performed to assess changes in insurance coverage for Medicaid and uninsured patients among states that chose to expand Medicaid coverage in 2014 under the ACA's provision versus those who opted out of Medicaid expansion. Since the database switched to using the American Joint Commission on Cancer (AJCC) 7th edition staging system in 2010, linear regression using data only from 2010 to 2015 was performed that assessed changes in cancer stage at diagnosis from 2010 to 2015 alone. After stratifying by cancer type (bone or soft-tissue sarcoma), Pearson chi square tests were used to assess for changes in the proportion of patients who were diagnosed with early, late, and unknown stage at presentation before Medicaid expansion (2011-2013) and after Medicaid expansion (2014-2015) among states that chose to expand versus those who did not. RESULTS: After stratifying by time cohorts: pre-ACA (2007 to 2010), pre-expansion (2011 to 2013) and post-expansion (2014 to 2015), we observed that the most dramatic changes occurred after Medicaid eligibility was expanded (2014 onwards), with Medicaid proportions increasing from 12% (pre-expansion, 2011 to 2013) to 14% (post-expansion, 2014 to 2015) (p < 0.001) and uninsured proportions decreasing from 5% (pre-expansion, 2011 to 2013) to 3% (post-expansion, 2014 to 2015) (p < 0.001). A differences-in-differences analysis that assessed the effect of Medicaid expansion showed that expanded states had an increase in the proportion of Medicaid patients compared with non-expanded states, (3.6% [95% confidence interval 0.4 to 6.8]; p = 0.03) from 2014 onwards. For the entire study sample, the proportion of early-stage diagnoses (I/II) increased from 56% (939 of 1667) in 2010 to 62% (1137 of 1840) in 2015 (p = 0.003). Similarly, the proportion of unknown stage diagnoses decreased from 11% (188 of 1667) in 2010 to 7% (128 of 1840) in 2015 (p = 0.002). There was no change in proportion of late-stage diagnoses (III/IV) from 32% (540 of 1667) in 2010 to 31% (575 of 1840) in 2015 (p = 0.13). CONCLUSION: Access to cancer care for patients with primary bone or soft-tissue sarcomas improved after the ACA was introduced, as evidenced by a decrease in the proportion of uninsured patients and corresponding increase in Medicaid coverage. Improvements in coverage were most significant among states that adopted the Medicaid expansion of 2014. Furthermore, we observed an increasing proportion of early-stage diagnoses after the ACA was implemented. The findings support the preservation of the ACA to ensure cancer care is equitable and accessible to all vulnerable patient populations. LEVEL OF EVIDENCE: Level III, therapeutic study.

Demographic and Clinicopathologic Factors of Patients With Hepatocellular Carcinoma in a Safety Net Hospital.

BACKGROUND: Safety net hospitals have historically cared for a disproportionate number of patients of low socioeconomic status, racial and ethnic minorities, and patients with cancer. These innate challenges make safety net hospitals important in understanding how to improve access to cancer care in order to fit the needs of vulnerable patients and ultimately improve their outcomes. The purpose of this study is to characterize the current state and treatment of hepatocellular carcinoma (HCC) at Ben Taub Hospital, a safety net hospital in Houston, Texas. MATERIALS AND METHODS: A retrospective chart review was performed to review the demographic characteristics, clinicopathologic data, treatment strategies, and outcomes of HCC patients at Ben Taub Hospital between January 2012 and December 2014. RESULTS: Two-hundred twenty-six men and 78 women with a mean age of 58 y underwent evaluation. Most (87%) were either uninsured or covered by Medicaid. The majority (69%) of patients presented with advanced (stage 2 or more) disease, with 58% of patients presenting with multiple lesions. Of the 40% that presented with a solitary lesion, the average size was 4.97 cm. Transarterial chemoembolization was used in 37% of patients and sorafenib was given to 26% of patients. Five patients underwent successful transplant. One hundred seventeen (38%) patients died of their disease, 25 patients are alive with no evidence of disease, and 159 patients have been lost to follow-up. CONCLUSIONS: Most patients with HCC presented to this safety net hospital with advanced disease; however, multiple local and systemic treatments were offered. Screening programs to detect HCC at an earlier stage are essential for successful long-term outcomes in a resource-strapped hospital with limited access to liver transplantation.

Limited Role for Routine Restaging After Neoadjuvant Therapy in Locally Advanced Rectal Cancer.

BACKGROUND: Although many patients with locally advanced rectal cancer undergo restaging imaging after neoadjuvant chemoradiotherapy and before surgery, the benefit of this practice is unclear. The purpose of this study was to examine the impact of reimaging on outcomes. MATERIALS AND METHODS: We performed a retrospective analysis of consecutive patients with stage 2 and 3 rectal adenocarcinoma treated with neoadjuvant chemoradiotherapy between May 2005 and April 2018. Patient and disease characteristics, imaging, treatment, and oncologic outcomes were compared between those who underwent restaging and those who went directly to surgery. Predictors of outcomes and cost effectiveness of restaging were determined. RESULTS: Of 224 patients, 146 underwent restaging. Six restaged patients had findings leading to a change in management. There was no difference in freedom from recurrence (P = 0.807) and overall survival (P = 0.684) based on restaging. Pretreatment carcinoembryonic antigen level >3 ng/mL (P = 0.010), clinical T stage 4 (P = 0.016), and pathologic T4 (P = 0.047) and N2 (P = 0.002) disease increased the risk of death, whereas adjuvant chemotherapy decreased the risk of death (P < 0.001) on multivariate analysis. Disease recurrence was lower with pelvic exenteration (P = 0.005) and in females (P = 0.039) and higher with pathologic N2 (P = 0.003) and N3 (P = 0.002) disease. The average cost of reimaging is $40,309 per change in management; however, $45 is saved per patient when downstream surgical costs are considered. CONCLUSIONS: Imaging restaging after neoadjuvant chemoradiotherapy in patients with locally advanced rectal cancer rarely changes treatment and does not improve survival. In a subset of patients at higher risk for worse outcome, reimaging may be beneficial.

Cost-Effectiveness of Sentinel Lymph Node Biopsy for Head and Neck Cutaneous Squamous Cell Carcinoma.

BACKGROUND: Sentinel lymph node biopsy (SLNB) has shown promise in identifying subclinical nodal metastasis in patients with high-risk cutaneous squamous cell carcinoma. However, low metastasis rates may indicate that performing such a procedure in all patients may be unnecessary and costly. MATERIALS AND METHODS: A decision model was developed to analyze costs and survival in patients with head and neck cutaneous squamous cell carcinoma based on their tumor and nodal metastasis staging and whether or not they received an SLNB. Incremental cost-effectiveness ratios were calculated based on the change in quality-adjusted life years (QALYs) and costs (US$) between the different options, with a threshold of $100,000 to determine the most cost-effective strategy. One-way, two-way, and probabilistic sensitivity analyses were performed to validate the results. RESULTS: Not performing an SLNB results in 12.26 QALYs and a cost of $3712.98. Performing an SLNB resulted in a 0.59 decrease in QALYs and an increase in cost of $1379.58 for an incremental cost-effectiveness ratio of -2338.27. This trend remained the same across all tumor stages and remained consistent within most sensitivity analyses. CONCLUSIONS: In patients with head and neck cutaneous squamous cell carcinoma, the most cost-effective strategy is to not perform SLNBs, regardless of the patient's stage. Low rates of nodal metastasis in addition to low disease-specific death rates were the significant factors in this outcome. Increasing the sensitivity of SLNB would not impact this recommendation unless the rate of nodal metastasis was significantly higher.

EBUS: Faster, cheaper and most effective in lung cancer staging.

The use of endobronchial ultrasound trans-bronchial needle aspiration (EBUS-TBNA) as the initial diagnostic and staging procedure in patients with suspected, non-metastatic lung cancer has gained substantial support, and is now recommended by numerous guidelines. Whereas considerable attention has been pointed to the reductions in costs achieved by EBUS-TBNA, that has not been the case for some of its more significant benefits, namely the reduction of the diagnostic work-up time and its ability to accurately assess and restage lymph nodes, which were previously stated incorrectly by CT or PET scan. Both these benefits translate into improved outcomes for patients, as delays are reduced, futile surgeries are prevented and curable operations can be performed on patients previously excluded by CT or PET scan. Indeed, the use of EBUS as the initial diagnostic and staging procedure has been proven to significantly increase survival, compared with conventional diagnostic and staging procedures, in a pragmatic, randomised controlled trial (Navani N. et al, 2015). The instalment of EBUS will have the greatest effect on overwhelmed, suboptimally functioning national healthcare systems, by decreasing the number of required diagnostic and staging procedures, therefore reducing both treatment delays and costs. The improved selection of surgical candidates by EBUS will result in improved patient outcomes. The latest findings regarding the benefits of EBUS are outlined in this review, which, to the best of our knowledge, is the first to emphasise the impact of the procedure, both on timing and costs of lung cancer staging, as well as on survival.

Cost-effectiveness of sentinel node biopsy and pathological ultrastaging in patients with early-stage cervical cancer.

BACKGROUND: The objective of this study was to determine the cost-effectiveness of radical hysterectomy (RH) and sentinel lymph node biopsy (SLNB) for the management of early-stage cervical cancer (stage IA2-IB1). METHODS: A simple decision tree model was developed to follow a simulated cohort of patients with early-stage cervical cancer treated with RH and 1 of 3 lymph node assessment strategies: systematic pelvic lymph node dissection (PLND), SLNB using technetium 99 (Tc99) and blue dye, and SLNB using Tc99 only. SLNB using indocyanine green (ICG) was used as an exploratory strategy. Relevant studies were identified to extract the probability data and utility parameters and to estimate quality-adjusted life-years (QALYs) and absolute life-years (ALYs). Only direct medical costs were modeled, and the time horizon for the study was 5 years. RESULTS: SLNB using Tc99 and blue dye cost $21,089 and yielded 4.54 QALYs and 4.90 ALYs. PLND cost $22,353 and yielded 4.47 QALYs and 4.91 ALYs. SLNB using blue dye and Tc99 was the most cost-effective strategy when ALYs were considered with an incremental cost-effectiveness ratio (ICER) of $144,531. When QALYs were considered, the SLNB technique using Tc99 and blue dye dominated all other strategies. SLNB using ICG cost $20,624 and yielded 4.90 ALYs and 4.54 QALYs. It was clinically superior to and less expensive than all other strategies when QALYs were the outcome of interest and had an ICER of $221,171 per ALY in comparison with RH plus PLND. CONCLUSIONS: SLNB using Tc99 and blue dye with ultrastaging is considered the most cost-effective strategy with respect to 5-year progression-free survival and morbidity-free survival. Although it was included only as an exploratory strategy in this study, SLNB with ICG has the potential to be the most cost-effective strategy.

AUA Policy Statement on the Use of Multiparametric Magnetic Resonance Imaging in the Diagnosis, Staging and Management of Prostate Cancer.

PURPOSE: We summarize the available data about the clinical and economic effectiveness of magnetic resonance imaging in the diagnosis and management of prostate cancer, and provide practical recommendations for its use in the screening, diagnosis, staging and surveillance of prostate cancer. MATERIALS AND METHODS: A panel of clinicians with expertise in the diagnosis and management of prostate cancer evaluated the current published literature on the use and effectiveness of magnetic resonance imaging for this disease. When adequate studies were available for analysis, recommendations were made on the basis of data and when adequate studies were not available, recommendations were made on the basis of expert consensus. RESULTS: At this time the data support the use of magnetic resonance imaging in patients with a previous negative biopsy and ongoing concerns about increased risk of prostate cancer. The data regarding its usefulness for initial biopsy suggest a possible role for magnetic resonance imaging in some circumstances. There is currently insufficient evidence to recommend magnetic resonance imaging for screening, staging or surveillance of prostate cancer. CONCLUSIONS: Although it adds cost to the management of prostate cancer, magnetic resonance imaging offers superior anatomic detail, and the ability to evaluate cellular density based on water diffusion and blood flow based on contrast enhancement. Imaging targeted biopsy may increase the diagnosis of clinically significant cancers by identifying specific lesions not visible on conventional ultrasound. The clinical indications for the use of magnetic resonance imaging in the management of prostate cancer are rapidly evolving.

Use of Lymph Node Ultrasound Prior to Sentinel Lymph Node Biopsy in 384 Patients with Melanoma: A Cost-Effectiveness Analysis. / Valor de la ecografía ganglionar previa a la biopsia del ganglio centinela en 384 pacientes con melanoma: análisis de coste-efectividad.

BACKGROUND AND OBJECTIVES: Locoregional lymph node ultrasound is not typically included in guidelines as part of the staging process prior to sentinel lymph node biopsy (SLNB). The objective of the present study was to make a clinical and economic analysis of lymph node ultrasound prior to SLNB. MATERIALS AND METHODS: We performed a retrospective study of 384 patients with clinical stage I-II primary melanoma who underwent locorregional lymph node ultrasound (with or without ultrasound-guided biopsy) prior to SLNB between 2004 and 2015. We evaluated the reliability and cost-effectiveness of the strategy. RESULTS: Use of locorregional lymph node ultrasound avoided SLNB in 23 patients (6%). Ultrasound had a sensitivity of 46% and specificity of 76% for the detection of metastatic lymph nodes that were not clinically palpable. False negatives were significantly more common in patients aged over 60 years and in tumors with a thickness of less than 2mm. The staging process using SLNB and ultrasound with ultrasound-guided biopsy produced an increase of €16.30 in the unit price. Our cost-effectiveness analysis identified the staging protocol with ultrasound and SLNB as the dominant strategy, with a lower cost-effectiveness ratio than the alternative, consisting of SLNB alone (8,095.24 vs. €28,605.00). CONCLUSIONS: Ultrasound with ultrasound-guided biopsy for the diagnostic staging of melanoma prior to SLNB is a useful and cost-effective tool. This procedure does not substitute SLNB, though it does allow to avoid SLNB in a not insignificant proportion of patients.

Yield of Computed Tomography at Baseline Staging of Melanoma.

BACKGROUND: Current guidelines call for baseline imaging only for very high-risk (T4b) primary cutaneous melanomas. OBJECTIVES: To estimate the frequency of computed tomography (CT) at baseline staging of primary cutaneous melanoma and the diagnostic yield of CT; and to describe the types and frequencies of incidentaloma findings. MATERIAL AND METHODS: Cross-sectional study of cutaneous melanoma cases (tumor classifications Tis to T4bN0M0) attended between 2008 and 2014 in a specialized melanoma unit. Reports of CT scans performed during baseline staging were reviewed to determine the frequency of positive scan results, incidentaloma findings, unit cost for detection of metastasis, and factors associated with the decision to order CT. RESULTS: CT results were available for 310 of the 419 patients included (73.99%). The tumor classifications were as follows: Tis, 17; T1, 137; T2, 71; T3, 48; and T4, 37. The CT results were negative in 81.61%, and incidentalomas were found in 18.06%. Additional primary tumors were found in 2 patients (0.64%), and metastasis was identified in one patient (0.32%). The cost of finding the case of metastasis was €71,234.90. A T2 tumor classification (odds ratio [OR], 8.73) and age under 70 years (OR, 3.53) were associated with greater likelihood of CT being ordered. Excision of the primary tumor in the melanoma unit (OR, 0.08) was associated with less likelihood of ordering CT. CONCLUSIONS: The results for this patient series support current recommendations restricting CT at baseline to cases where there is high risk of metastasis (stagesiiC-iii).

Evaluation of patient registries supporting reimbursement decisions: the case of oxaliplatin for treatment of stage III colon cancer.

BACKGROUND: Access with evidence development has been established for expensive intramural drugs in The Netherlands. The procedure involves a 4-year period of conditional reimbursement. During this period, additional evidence has to be gathered usually through a patient registry. Given the costs and time involved in gathering the data, it is important to carefully evaluate the registry. OBJECTIVES: This study aimed to develop a model for the regular evaluation of patient registries during an access with evidence development process and find the optimal length of the registry period. METHODS: We used data from a recent registry in The Netherlands on oxaliplatin as a treatment option for stage III colon cancer. We added simulated follow-up data to the empirical data available and applied value of information analysis to balance the gains of extending the period and amount of data gathering against the costs of registering patients. RESULTS: We show that given the assumptions on cohort size, follow-up time, and purpose of the registry, the current (partly simulated) registry was not very efficient. Notably, the observation period could have been stopped to make a definite reimbursement decision after a maximum of 2 years rather than the fixed 4-year period. CONCLUSIONS: Patient registries may be an efficient way to gather data on new medical treatments, but they need to be carefully designed and evaluated, in particular regarding their follow-up time. For each purpose, data gathering can be tailored to make sure decisions are taken at the moment that sufficient data are available.

[Treatment costs of malignant cervical cancer in Poland in 2011-2012--the case of Silesian Voivodeship]. / Koszty leczenia nowotworów zlosliwych szyjki macicy w Polsce w latach 2011-2012 na przykladzie województwa slaskiego.

OBJECTIVES: As far as health economics is concerned, it is hard to determine the only useful tool which would disclose the actual costs associated with cancer. We analyzed hospitalization costs, which create the highest rate among all malignant cervical cancer-related medical costs. The main aim of the study was to evaluate the real costs of medical treatment in the case of patients diagnosed with cervical cancer based on the group with the primary and coexisting diagnoses. MATERIAL AND METHODS: The analyzed data from 2011-2012 were obtained from the Silesian branch of the National Health Fund, which financed medical expenses due to the diagnosis of cancer in health facilities which have the agreement for such treatment. RESULTS: A total of 4 540 hospitalization-related health benefits were realized, with the final total cost was PLN 8 766 547, in the presented group of 2261 patients. The most popular procedures in patients with the diagnosis from the C53 group, included chemotherapy together with oncological hospitalization (over 62%). The vast majority of the realized procedures were treatments of the reproductive system (38%) and teleradiotherapy (about 31%). CONCLUSIONS: Lack of efficient procedures of data collection for cancer advancement hinders the economic analyses, which should constitute the foundation for the discussion about cost effectiveness of selected procedures. Adequate methods for the monitoring of direct and indirect costs associated with cervical cancer treatment ought to be created.

A composite measure of personal financial burden among patients with stage III colorectal cancer.

BACKGROUND: Despite improved survival with chemotherapy for stage III colorectal cancer (CRC), patients may suffer substantial economic hardship during treatment. Methods for quantifying financial burden in CRC patients are lacking. OBJECTIVE: To derive and validate a novel patient-reported measure of personal financial burden during CRC treatment. DATA COLLECTION: Within a population-based survey of patients in the Detroit and Georgia Surveillance, Epidemiology and End Results regions diagnosed with stage III CRC between 2011 and 2013, we asked 7 binary questions assessing effects of disease and treatment on personal finances. DATA ANALYSIS: We used factor analysis to compute a composite measure of financial burden. We used χ tests to evaluate relationships between individual components of financial burden and chemotherapy use with χ analyses. We used Mantel-Haenszel χ trend tests to examine relationships between the composite financial burden metric and chemotherapy use. RESULTS: Among 956 patient surveys (66% response rate), factor analysis of 7 burden items yielded a single-factor solution. Factor loadings of 6 items were >0.4; these were included in the composite score. Internal consistency was high (Cronbach α=0.79). The mean financial burden score among all respondents was 1.72 (range, 0-6). The 812 (85%) who reported chemotherapy use had significantly higher financial burden scores than those who did not (mean burden score 1.88 vs. 0.88, P<0.001). CONCLUSIONS: Financial burden is high among CRC patients, particularly those who use adjuvant chemotherapy. We encourage use of our instrument to validate our measure in the identification of patients in need of additional financial support during treatment.

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.

Intended versus inferred management after PET for cancer restaging: analysis of Medicare claims linked to a coverage with evidence development registry.

BACKGROUND: The National Oncologic PET Registry (NOPR) ascertained changes in the intended management of cancer patients using questionnaire data obtained before and after positron emission tomography (PET) under Medicare's coverage with evidence development policy. OBJECTIVE: To assess the concordance between intended care plans and care received as ascertained through administrative claims data. RESEARCH DESIGN: Analysis of linked data of NOPR participants from 2006 to 2008 and their corresponding Medicare claims. SUBJECTS: Consenting patients aged older than 65 years having their first PET for restaging of bladder, kidney, ovarian, pancreas, prostate, small cell lung, or stomach cancer. MEASURES: : Agreement (positive predictive values and κ) between NOPR post-PET intended management plans for treatment (systemic therapy, radiotherapy, surgery, or combinations), biopsy, or watching as compared to claims-inferred care 30 days after PET. RESULTS: A total of 8460 patients with linked data were assessed. A total of 43.5% had metastatic disease and 45.3% had treatment planned (predominantly systemic therapy only), 11.1% biopsy and 43.5% watching. Claims-confirmed intended plans (positive predictive value) for single-mode systemic therapy in 62.0%, radiation in 66.0%, surgery in 45.6%, and biopsy in 55.7%. A total of 25.7% of patients with a plan of watching had treatment claims. By cancer type, κ ranged for systemic therapy only from 0.17 to 0.40 and for watching from 0.21 to 0.41. Agreement rates varied by cancer types but were minimally associated with patient age, performance status, comorbidity, or stage. CONCLUSIONS: Among elderly cancer patients undergoing PET for restaging, there was moderate concordance between their physicians' planned management and claims-inferred actions within a narrow time window. When higher accuracy levels are required in future coverage with evidence development studies, alternative designs will be needed.

Neighborhood socio-economic disadvantage and race/ethnicity as predictors of breast cancer stage at diagnosis.

BACKGROUND: This study investigated the role of key individual- and community-level determinants to explore persisting racial/ethnic disparities in breast cancer stage at diagnosis in California during 1990 and 2000. METHODS: We examined socio-demographic determinants and changes in breast cancer stage at diagnosis in California during 1990 and 2000. In situ, local, regional, and distant diagnoses were examined by individual (age, race/ethnicity, and marital status) and community (income and education by zip code) characteristics. Community variables were constructed using the California Cancer Registry 1990-2000 and the 1990 and 2000 U.S. Census. RESULTS: From 1990 to 2000, there was an overall increase in the percent of in situ diagnoses and a significant decrease in regional and distant diagnoses. Among white and Asian/Pacific Islander women, a significant percent increase was observed for in situ diagnoses, and significant decreases in regional and distant diagnoses. Black women had a significant decrease in distant -stage diagnoses, and Hispanic women showed no significant changes in any diagnosis during this time period. The percent increase of in situ cases diagnosed between 1990 and 2000 was observed even among zip codes with low income and education levels. We also found a significant percent decrease in distant cases for the quartiles with the most poverty and least education. CONCLUSIONS: Hispanic women showed the least improvement in breast cancer stage at diagnosis from 1990 to 2000. Breast cancer screening and education programs that target under-served communities, such as the rapidly growing Hispanic population, are needed in California.

Toluidine blue: yet another low cost method for screening oral cavity tumour margins in third world countries.

OBJECTIVE: To use toluidine blue intra-operatively to identify tumour involved margins after the removal of oral cavity squamous cell carcinoma, and to compare the findings with those of final histopathology. METHODS: The study was conducted at the Aga Khan University Hospital from December 1, 2009, to March 14, 2010, and comprised 56 consecutive patients with biopsy-proven squamous cell carcinoma of oral cavity regardless of grade and stage of tumour. Intra-operatively toluidine blue was used on the resected tumour margins and the staining patterns were assessed. Results were then compared with the final histopathology report. RESULTS: A total of 11(19.64%) margins were positive with toluidine blue staining out of which 8 (14.28%) were false positive. Sensitivity and specificity was found to be 100% and 84.9% respectively with a positive predictive value of 27.2%; a negative predictive value of 100%; and diagnostic accuracy of 85.71%. CONCLUSION: Toluidine blue costs only Rs25 (USD 0.30) and takes only 5 minutes for application and interpretation. It can be used with significant confidence in smaller lesions (T-l and T-II) as an alternative to frozen sections in developing countries where facilities are unavailable. Its use in larger lesions (T-lll and TIV) remains the topic of controversy and awaits a multi centre trial with a larger cohort.

Cost comparison of axillary sentinel lymph node detection and axillary lymphadenectomy in early breast cancer. A national study based on a prospective multi-institutional series of 985 patients 'on behalf of the Group of Surgeons from the French Unicancer Federation'.

BACKGROUND: Our objective was to assess the global cost of the sentinel lymph node detection [axillary sentinel lymph node detection (ASLND)] compared with standard axillary lymphadenectomy [axillary lymph node dissection (ALND)] for early breast cancer patients. PATIENTS AND METHODS: We conducted a prospective, multi-institutional, observational, cost comparative analysis. Cost calculations were realized with the micro-costing method from the diagnosis until 1 month after the last surgery. RESULTS: Eight hundred and thirty nine patients were included in the ASLND group and 146 in the ALND group. The cost generated for a patient with an ASLND, with one preoperative scintigraphy, a combined method for sentinel node detection, an intraoperative pathological analysis without lymphadenectomy, was lower than the cost generated for a patient with lymphadenectomy [€ 2947 (σ = 580) versus € 3331 (σ = 902); P = 0.0001]. CONCLUSION: ASLND, involving expensive techniques, was finally less expensive than ALND. The length of hospital stay was the cost driver of these procedures. The current observational study points the heterogeneous practices for this validated and largely diffused technique. Several technical choices have an impact on the cost of ASLND, as intraoperative analysis allowing to reduce rehospitalization rate for secondary lymphadenectomy or preoperative scintigraphy, suggesting possible savings on hospital resources.
