RESUMO

BACKGROUND: Opportunistic salpingectomy at the time of hysterectomy or as an alternative to bilateral tubal ligation may reduce the incidence of ovarian cancer, because it has been demonstrated that most serous ovarian cancers begin in the fallopian tubes. However, salpingectomy at the time of sterilization is not always financially covered by third-party payers, and this represents a barrier to adoption. Routine salpingectomy has become more common but is not always practiced at the time of hysterectomy. OBJECTIVE: This study aimed to determine the impact of opportunistic salpingectomy as an alternative tubal ligation and routine salpingectomy at the time of hysterectomy on ovarian cancer mortality and overall cost. STUDY DESIGN: An 8-state Markov state transition model was constructed, including hysterectomy, tubal ligation, and ovarian cancer. Transition probabilities were informed by previously reported population data and include age-adjusted rates of elective sterilization and hysterectomy. This model was used to predict ovarian cancer incidence and the cost effectiveness of opportunistic salpingectomy. Testing of this model suggested that it accurately predicted overall life expectancy and closely predicted the rate of hysterectomy in the population. The model may underestimate the rate of tubal sterilization, making it conservative with respect to the benefits of salpingectomy. RESULTS: The recursive Markov model was run from ages 20 to 85 years in 1-year intervals with a half step correction and included age-adjusted rates of tubal ligation, hysterectomy (with and without oophorectomy), and ovarian cancer. The model predicts that opportunistic salpingectomy at the time of tubal ligation will reduce ovarian cancer mortality by 8.13%. Opportunistic salpingectomy at the time of hysterectomy will reduce ovarian cancer mortality by 6.34% for a combined decrease of 14.5%. Both strategies are cost effective when considering only the cost of the opportunistic salpingectomy. The excess cost of opportunistic salpingectomy at the time of tubal ligation was $433.91 with an incremental cost-effective ratio of $6401 per life-year and $5469 per quality-adjusted life year gained when adjusting for ovarian cancer with a utility of 0.64. The incremental cost-effective ratio for opportunistic salpingectomy during hysterectomy at a cost of $124.70 was $2006 per life-year and $1667 per quality-adjusted life year. When considering the impact of ovarian cancer prevention with respect to the cost of ovarian cancer treatment, opportunistic salpingectomy may produce a substantial healthcare savings. Utilizing a 3% discount rate, it is estimated that the total savings for universal salpingectomy could be as high as $445 million annually in the United States. A sensitivity analysis around the benefit of opportunistic salpingectomy suggests that this procedure will be cost effective even if salpingectomy provides only a modest reduction in the risk of ovarian cancer. CONCLUSION: It is estimated that universal opportunistic salpingectomy may prevent 1854 deaths per year from ovarian cancer and may reduce healthcare costs. Given these data, universal opportunistic salpingectomy should be considered at the time of tubal ligation and hysterectomy and covered by third-party payers.

RESUMO

BACKGROUND: Bisphosphonates reduce the risk of fractures associated with osteoporosis but increase the risk of atypical subtrochanteric femur fractures. After unilateral atypical femur fracture, there is risk of contralateral fracture, but the indications for prophylactic fixation are controversial. QUESTIONS/PURPOSES: The purpose of this study is to use Markov modeling to determine whether contralateral prophylactic femur fracture fixation is cost-effective after a bisphosphonate-associated atypical femur fracture and, if so, what patient-related factors may influence that determination. METHODS: Markov modeling was used to determine the cost-effectiveness of contralateral prophylactic fixation after an initial atypical femur fracture. Simulated patients aged 60 to 90 years were included and separated into standard and high fracture risk cohorts. Patients with standard fracture risk were defined as those presenting with one atypical femur fracture but without symptoms or findings in the contralateral femur, whereas patients with high fracture risk were typified as those with more than one risk factor, including Asian ethnicity, prodromal pain, femoral geometry changes, or radiographic findings in the contralateral femur. Outcome probabilities and utilities were derived from studies matching to patient characteristics, and fragility fracture literature was used when atypical femur fracture data were not available. Associated costs were largely derived from Medicare 2015 reimbursement rates. Sensitivity analysis was performed on all model parameters within defined ranges. RESULTS: Prophylactic fixation for a 70-year-old patient with standard risk for fracture costs USD 131,300/quality-adjusted life-year (QALY) and for high-risk patients costs USD 22,400/QALY. Sensitivity analysis revealed that prophylaxis for high-risk patients is cost-effective at USD 100,000/QALY when the cost of prophylaxis was less than USD 29,400, the probability of prophylaxis complications was less than 21%, or if the patient was younger than 89 years old. The parameters to which the model was most sensitive were the cost of prophylaxis, patient age, and probability of prophylaxis-related complications. CONCLUSIONS: Prophylactic fixation of the contralateral side after unilateral atypical femur fracture is not cost-effective for standard-risk patients but is cost-effective among high-risk patients between 60 and 89 years of age with a high risk for an atypical femur fracture defined by patients with more than one risk factor such as Asian ethnicity, prodromal pain, varus proximal femur geometry, femoral bowing, or radiographic changes such as periosteal beaking and a transverse radiolucent line. However, our findings are based on several key assumptions for modeling such as the probability of fractures and complications, the costs associated for each health state, and the risks of surgical treatment. Future research should prospectively evaluate the degree of risk contributed by known radiographic and demographic parameters to guide management of the contralateral femur after a patient presents with an atypical femur fracture. LEVEL OF EVIDENCE: Level III, economic and decision analyses.

RESUMO

OBJECTIVE: To assess the usefulness of risk reduction salpingo-oophorectomy in cases with mutation of the BRCA1 gene in Colombia. MATERIAL AND METHODS: Cost-effectiveness analysis in which three processes are incorporated: a. Patients with screening tests for breast and ovarian cancer. b. Risk reduction surgery in the fallopian tubes and ovaries c. Reductive surgery in the fallopian tubes and ovaries with bilateral mastectomy. The outcome is evaluated as the gain in years of survival. RESULTS: The cohort with risk reduction surgery in the fallopian tubes and ovaries and bilateral mastectomy is the one with the highest gain with 13 years, while the risk reduction surgery in the fallopian tubes and ovaries gain 4.95 years with respect to the follow-up group. CONCLUSIONS: The three options evaluated are acceptable, but of them the one with the greatest gain in survival is the combination of risk-reducing surgery in the fallopian tubes and ovaries with bilateral mastectomy.

RESUMO

OBJECTIVE: Ovarian cancer is the most lethal gynaecologic cancer. Disease prevention may be the only method to reduce the incidence of ovarian cancer. The Society of Gynecologic Oncology advised that salpingectomies may be an appropriate and feasible strategy for ovarian cancer risk reduction. This study conducted an economic evaluation from a societal perspective of bilateral salpingectomies versus conventional sterilization techniques in the prevention of ovarian cancer. STUDY DESIGN: We performed a micro-cost analysis comparing laparoscopic tubal coagulation, tubal clips and bilateral salpingectomies at the Michael Garron Hospital, formerly the Toronto East General Hospital, from 2015 to 2016. A Markov model was used in the cost-effectiveness and cost-utility analyses on these surgical procedures in ovarian cancer prevention. Costs were derived for the number ovarian cancer cases observed per sterilization method, cancer treatment, and associated procedural costs over each cancer patient's lifetime. The number of bilateral salpingectomies required to prevent an additional ovarian cancer case with the recommended treatment was also estimated. RESULTS: Bilateral salpingectomies performed at the Michael Garron Hospital generated savings of $7823 per life-year gained (95% CI $3248-$10 190; incremental cost [ΔC] -$907, incremental effect [ΔE] 0.11 life-years gained) compared with tubal clips and savings of $6315 per life-year gained (95% CI -$6360 to $9342; ΔC -$755, ΔE 0.11 life-years gained) compared with tubal coagulation. Most importantly, for every 150 bilateral salpingectomies performed, one case of ovarian cancer may be prevented. CONCLUSION: Laparoscopic bilateral salpingectomy is the dominant, cost-effective surgical strategy when compared to tubal clips and tubal coagulation to prevent ovarian cancer. Laparoscopic bilateral salpingectomies reduce costs and enhance quality-adjusted life-years relative to the two alternative treatments.

RESUMO

BACKGROUND: Population-based BRCA1/BRCA2 founder-mutation testing has been demonstrated as cost effective compared with family history based testing in Ashkenazi Jewish women. However, only 1 of the 3 Ashkenazi Jewish BRCA1/BRCA2 founder mutations (185delAG[c.68_69delAG]), 5382insC[c.5266dupC]), and 6174delT[c.5946delT]) is found in the Sephardi Jewish population (185delAG[c.68_69delAG]), and the overall prevalence of BRCA mutations in the Sephardi Jewish population is accordingly lower (0.7% compared with 2.5% in the Ashkenazi Jewish population). Cost-effectiveness analyses of BRCA testing have not previously been performed at these lower BRCA prevalence levels seen in the Sephardi Jewish population. Here we present a cost-effectiveness analysis for UK and US populations comparing population testing with clinical criteria/family history-based testing in Sephardi Jewish women. STUDY DESIGN: A Markov model was built comparing the lifetime costs and effects of population-based BRCA1 testing, with testing using family history-based clinical criteria in Sephardi Jewish women aged ≥30 years. BRCA1 carriers identified were offered magnetic resonance imaging/mammograms and risk-reducing surgery. Costs are reported at 2015 prices. Outcomes include breast cancer, ovarian cancer, and excess deaths from heart disease. All costs and outcomes are discounted at 3.5%. The time horizon is lifetime, and perspective is payer. The incremental cost-effectiveness ratio per quality-adjusted life-year was calculated. Parameter uncertainty was evaluated through 1-way and probabilistic sensitivity analysis. RESULTS: Population testing resulted in gain in life expectancy of 12 months (quality-adjusted life-year = 1.00). The baseline discounted incremental cost-effectiveness ratio for UK population-based testing was £67.04/quality-adjusted life-year and for US population was $308.42/quality-adjusted life-year. Results were robust in the 1-way sensitivity analysis. The probabilistic sensitivity analysis showed 100% of simulations were cost effective at £20,000/quality-adjusted life-year UK and the $100,000/quality-adjusted life-year US willingness-to-pay thresholds. Scenario analysis showed that population testing remains cost effective in UK and US populations, even if premenopausal oophorectomy does not reduce breast cancer risk or if hormone replacement therapy compliance is nil. CONCLUSION: Population-based BRCA1 testing is highly cost effective compared with clinical criteria-driven approach in Sephardi Jewish women. This supports changing the paradigm to population-based BRCA testing in the Jewish population, regardless of Ashkenazi/Sephardi ancestry.

RESUMO

Ovarian cancer remains to be the most lethal of all gynecologic malignancies. There is no effective screening test proven to reduce the mortality associated with this disease. Costs of treating ovarian cancer are substantial and among the highest of all cancer types. Therefore, it is essential to pursue strategies to prevent ovarian cancer that are cost-effective in the context of our health care system. There are 2 subgroups of women for whom ovarian cancer prevention strategies have been evaluated for effectiveness and costs: (1) general population at risk, and (2) BRCA mutation carriers with a high lifetime risk.

RESUMO

BACKGROUND: Population-based BRCA1/BRCA2 testing has been found to be cost-effective compared with family history-based testing in Ashkenazi-Jewish women were >30 years old with 4 Ashkenazi-Jewish grandparents. However, individuals may have 1, 2, or 3 Ashkenazi-Jewish grandparents, and cost-effectiveness data are lacking at these lower BRCA prevalence estimates. We present an updated cost-effectiveness analysis of population BRCA1/BRCA2 testing for women with 1, 2, and 3 Ashkenazi-Jewish grandparents. STUDY DESIGN: Decision analysis model. METHODS: Lifetime costs and effects of population and family history-based testing were compared with the use of a decision analysis model. 56% BRCA carriers are missed by family history criteria alone. Analyses were conducted for United Kingdom and United States populations. Model parameters were obtained from the Genetic Cancer Prediction through Population Screening trial and published literature. Model parameters and BRCA population prevalence for individuals with 3, 2, or 1 Ashkenazi-Jewish grandparent were adjusted for the relative frequency of BRCA mutations in the Ashkenazi-Jewish and general populations. Incremental cost-effectiveness ratios were calculated for all Ashkenazi-Jewish grandparent scenarios. Costs, along with outcomes, were discounted at 3.5%. The time horizon of the analysis is "life-time," and perspective is "payer." Probabilistic sensitivity analysis evaluated model uncertainty. RESULTS: Population testing for BRCA mutations is cost-saving in Ashkenazi-Jewish women with 2, 3, or 4 grandparents (22-33 days life-gained) in the United Kingdom and 1, 2, 3, or 4 grandparents (12-26 days life-gained) in the United States populations, respectively. It is also extremely cost-effective in women in the United Kingdom with just 1 Ashkenazi-Jewish grandparent with an incremental cost-effectiveness ratio of £863 per quality-adjusted life-years and 15 days life gained. Results show that population-testing remains cost-effective at the £20,000-30000 per quality-adjusted life-years and $100,000 per quality-adjusted life-years willingness-to-pay thresholds for all 4 Ashkenazi-Jewish grandparent scenarios, with ≥95% simulations found to be cost-effective on probabilistic sensitivity analysis. Population-testing remains cost-effective in the absence of reduction in breast cancer risk from oophorectomy and at lower risk-reducing mastectomy (13%) or risk-reducing salpingo-oophorectomy (20%) rates. CONCLUSION: Population testing for BRCA mutations with varying levels of Ashkenazi-Jewish ancestry is cost-effective in the United Kingdom and the United States. These results support population testing in Ashkenazi-Jewish women with 1-4 Ashkenazi-Jewish grandparent ancestry.

RESUMO

BACKGROUND: Fallopian tubes are commonly removed during laparoscopic and open hysterectomy to prevent ovarian and tubal cancer but are not routinely removed during vaginal hysterectomy because of perceptions of increased morbidity, difficulty, or inadequate surgical training. OBJECTIVE: We sought to quantify complications and costs associated with a strategy of planned salpingectomy during vaginal hysterectomy. STUDY DESIGN: We created a decision analysis model using TreeAgePro. Effectiveness outcomes included ovarian cancer incidence and mortality as well as major surgical complications. Modeled complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. We also modeled subsequent benign adnexal surgery beyond the postoperative window. Those whose procedures were converted from a vaginal route were assumed to undergo bilateral salpingectomy, regardless of treatment group, following American College of Obstetricians and Gynecologists guidelines. Costs were gathered from published literature and Medicare reimbursement data, with internal cost data from 892 hysterectomies at a single institution used to estimate costs when necessary. Complication rates were determined from published literature and from 13,397 vaginal hysterectomies recorded in the National Surgical Quality Improvement Program database from 2008 through 2013. RESULTS: Switching from a policy of vaginal hysterectomy alone to a policy of routine planned salpingectomy prevents a diagnosis of ovarian cancer in 1 of every 225 women having surgery and prevents death from ovarian cancer in 1 of every 450 women having surgery. Overall, salpingectomy was a less expensive strategy than not performing salpingectomy ($7350.62 vs $8113.45). Sensitivity analysis demonstrated the driving force behind increased costs was the increased risk of subsequent benign adnexal surgery among women retaining their tubes. Planned opportunistic salpingectomy had more major complications than hysterectomy alone (7.95% vs 7.68%). Major complications included transfusion, conversion to laparotomy or laparoscopy, abscess/hematoma requiring intervention, ileus, readmission, and reoperation within 30 days. Therefore, routine salpingectomy results in 0.61 additional complications per case of cancer prevented and 1.21 additional complications per death prevented. A surgeon therefore must withstand an additional ∼3 complications to prevent 5 cancer diagnoses and ∼6 additional complications to prevent 5 cancer deaths. CONCLUSION: Salpingectomy should routinely be performed with vaginal hysterectomy because it was the dominant and therefore cost-effective strategy. Complications are minimally increased, but the trade-off with cancer prevention is highly favorable.

RESUMO

OBJECTIVES: Data suggesting a link between the fallopian tube and ovarian cancer have led to an increase in rates of salpingectomy at the time of pelvic surgery, a practice known as opportunistic salpingectomy (OS). However, the potential benefits, risks and costs for this new practice are not well established. Our objective was to assess the cost-effectiveness of opportunistic salpingectomy at the time of laparoscopic permanent contraception or hysterectomy for benign indications. METHODS: We created two models to compare the cost-effectiveness of salpingectomy versus usual care. The hypothetical study population is 50,000 women aged 45 undergoing laparoscopic hysterectomy with ovarian preservation for benign indications, and 300,000 women aged 35 undergoing laparoscopic permanent contraception. SEER data were used for probabilities of ovarian cancer cases and deaths. The ovarian cancer risk reduction, complication rates, utilities and associated costs were obtained from published literature. Sensitivity analyses and Monte Carlo simulation were performed, and incremental cost-effectiveness ratios (ICERs) were calculated to determine the cost per quality adjusted life year (QALY) gained. RESULTS: In the laparoscopic hysterectomy cohort, OS is cost saving and would yield $23.9 million in health care dollars saved. In the laparoscopic permanent contraception cohort, OS is cost-effective with an ICER of $31,432/QALY compared to tubal ligation, and remains cost-effective as long as it reduces ovarian cancer risk by 54%. Monte Carlo simulation demonstrated cost-effectiveness with hysterectomy and permanent contraception in 62.3% and 55% of trials, respectively. CONCLUSIONS: Opportunistic salpingectomy for low-risk women undergoing pelvic surgery may be a cost-effective strategy for decreasing ovarian cancer risk at time of hysterectomy or permanent contraception. In our model, salpingectomy was cost-effective with both procedures, but the advantage greater at time of hysterectomy.

RESUMO

OBJECTIVE: To estimate the survival benefit and cost-effectiveness of performing hysterectomy during risk-reducing salpingo-oophorectomy (RRSO) for BRCA1 mutation carriers. METHODS: Based on a recent prospective cohort study indicating an elevated incidence of serous/serous-like uterine cancers among BRCA1 mutation carriers, we constructed a modified Markov decision model from a payer perspective to inform decisions about performance of hysterectomy during RRSO at age 40. We assumed patients had previously undergone a risk-reducing mastectomy and had a residual risk of death from breast or ovarian cancer. Disease-specific survival, age-adjusted competing hysterectomy rates, and deaths from other causes were incorporated. Costs of risk-reducing surgery, competing hysterectomy, and care for serous/serous-like uterine cancer were included. RESULTS: A 40year old woman who undergoes RRSO+Hysterectomy gains 4.9 additional months of overall survival (40.38 versus 39.97 undiscounted years) compared to RRSO alone. The lifetime probabilities of developing or dying from serous/serous-like uterine cancer in the RRSO group are 3.5% and 2%, respectively. The RRSO alone strategy has an average cost of $9013 compared to $8803 for RRSO+Hysterectomy, and is dominated (less effective and more costly) when compared to RRSO+Hysterectomy. In an alternative analysis, delayed hysterectomy remains a cost-effective prevention strategy with an ICER of less than $100,000/year for up to 25years following RRSO at age 40. CONCLUSIONS: The addition of hysterectomy to RRSO in a 40year old BRCA1 mutation carrier results in a mean gain of 4.9 additional months of life and is cost-effective.

RESUMO

OBJECTIVES: Risk-reducing surgeries are a feasible option for mitigating the risk in individuals with inherited susceptibility to cancer, but are the procedures cost-effective in the current health-care system in Germany? This study compared the health-care costs for bilateral risk-reducing mastectomy (BRRM) and risk-reducing (bilateral) salpingo-oophorectomy (RRSO) with cancer treatment costs that could potentially be prevented. PATIENTS AND METHODS: The analysis is based on interdisciplinary consultations with individuals with a high familial risk for breast and ovarian cancer at the University Breast Center for Franconia (Germany) between 2009 and 2013 (370 consultations; 44 patients with BRCA1 mutations and 26 with BRCA2 mutations). Health-care costs for risk-reducing surgeries in BRCA mutation carriers were calculated as reimbursements in the German diagnosis-related groups (DRG) hospital pricing system. These costs for the health-care system were compared with the potential cancer treatment costs that could possibly be prevented by risk-reducing surgeries. RESULTS: Long-term health-care costs can be reduced by risk-reducing surgeries after genetic testing in BRCA mutation carriers. The health-care system in Germany would have saved € 136,295 if BRRM had been performed and € 791,653 if RRSO had been performed before the development of cancer in only 50% of the 70 mutation carriers seen in our center. Moreover, in patients with combined RRSO and BRRM (without breast reconstruction), one further life-year for a 40-year-old BRCA mutation carrier would cost € 2,183. CONCLUSION: Intensive care, including risk-reducing surgeries in BRCA mutation carriers, is cost-effective from the point of view of the health-care system in Germany.

RESUMO

BACKGROUND: The past decade has seen an increasing prevalence of prophylactic mastectomy with decreasing ages of patients treated for breast cancer. Data are limited on the fiscal impacts of contralateral prophylactic mastectomy trends, and no study has compared bilateral prophylactic mastectomy with reconstruction to surveillance in high-risk patients. METHODS: Lifetime third-party payer costs over 30 years were estimated with 2013 Medicare reimbursement rates. Costs were estimated for patients choosing contralateral or bilateral prophylactic mastectomy versus surveillance, with immediate reconstructions using a single-stage implant, tissue expander, or perforator-based free flap approach. Published cancer incidence rates predicted the percentage of surveillance patients that would require mastectomies. Sensitivity analyses were conducted that varied cost growth, discount rate, cancer incidence rate, and other variables. Lifetime costs and present values (3 percent discount rate) were estimated. RESULTS: Lifetime prophylactic mastectomy costs were lower than surveillance costs, $1292 to $1993 lower for contralateral prophylactic mastectomy and $15,668 to $21,342 lower for bilateral prophylactic mastectomy, depending on the reconstruction. Present value estimates were slightly higher for contralateral prophylactic mastectomy over contralateral surveillance but still cost saving for bilateral prophylactic mastectomy compared with bilateral surveillance. Present value estimates are also cost saving for contralateral prophylactic mastectomy when the modeled contralateral breast cancer incidence rate is increased to at least 0.6 percent per year. CONCLUSIONS: These findings are consistent with contralateral and bilateral prophylactic mastectomy being cost saving in many scenarios, regardless of the reconstructive option chosen. They suggest that physicians and patients should continue to receive flexibility in deciding how best to proceed clinically in each case.

RESUMO

BACKGROUND: For patients with BRCA mutations, a simultaneous procedure that combines risk-reducing operation of the ovaries with mastectomy and breast reconstruction is an attractive option. The purpose of this study was to assess the outcomes and associated cost of performing simultaneous mastectomy, free flap breast reconstruction (FFR), and gynecologic procedure. METHODS: A retrospective chart review was performed on patients who underwent bilateral FFR from 2005 to 2012. Four hundred twenty-two patients were identified who underwent bilateral breast reconstruction without a simultaneous gynecologic procedure. Forty-two patients were identified who underwent simultaneous FFR and gynecologic procedure. Clinical outcomes, medical and surgical complications, and hospital costs were analyzed and compared between the 2 groups. RESULTS: A total of 928 free flaps were performed on 464 patients. Forty-two patients had a simultaneous gynecologic procedure at the time of breast reconstruction. Twenty-three (54.8%) patients within the study group underwent simultaneous bilateral salpingo oophorectomy (BSO), whereas the other 19 (45.2%) underwent both total abdominal hysterectomy and BSO. Eighty-four free flaps were performed in this cohort (n = 48 muscle-sparing transverse rectus abdominis myocutaneous, n = 28 deep inferior epigastric perforator, n = 4 superficial inferior epigastric perforator, n = 4 transverse upper gracilis). Mean operative time was 573 minutes. Mean hospitalization was 5.3 days. Postoperatively, 4 patients experienced an anastomotic thrombosis; 2 patients had an arterial thrombosis and 2 patients had a venous thrombosis. There were 2 flap failures, 2 patients with mastectomy skin flap necrosis, 11 patients who developed breast wound healing complications, and 6 patients who developed abdominal wound healing complications. Surgical and medical complication rates did not differ significantly between those who had simultaneous procedures, and those who did not. There was a statistically significant difference in the average total cost when comparing the group of patients receiving prophylactic mastectomy/FFR/total abdominal hysterectomy and/or BSO versus the patients who did not have combined gynecologic procedures at the time of reconstruction ($22,994.52 vs $21,029.23, P = 0.0004). CONCLUSIONS: For the high-risk breast cancer patient, a combined mastectomy, free flap reconstruction, and gynecologic procedure represents an attractive and safe option.

RESUMO

Breast cancer prevention can be provided by using SERMs or aromatase inhibitors depending on the ovarian status, with a global risk reduction of 50 to 60%. Prophylactic annexectomy offered to reduce ovarian risk in BRCA mutation carriers also lowers breast cancer risk by 50%. Main side effects include deep vein thrombosis for SERMs, hot flushes and joint pain (although less frequently than initially suspected) with aromatase inhibitors. Other strategies based on progesterone, insulin or prolactin signaling modulation may be offered in the future. Criteria for candidate selection remain to be established.

RESUMO

BACKGROUND: The role of routine prophylactic central neck dissection (CND) in papillary thyroid cancer (PTC) remains controversial. The aim of this study was to evaluate the cost utility of the addition of routine CND in patients with low-risk PTC compared with total thyroidectomy (TT) alone. METHODS: A Markov model for low-risk PTC was constructed with a treatment algorithm based on the American Thyroid Association guidelines for well-differentiated thyroid carcinoma. Utilities and outcome probabilities were derived from published medical literature. US 2010 costs were examined from a society perspective using Medicare reimbursement rates and opportunity loss based on published US government data. Monte Carlo simulation and sensitivity analysis were used to examine the uncertainty of probability, cost and utility estimates. RESULTS: Initial TT alone is more cost-effective than TT with CND, resulting in a cost savings of US $5763 per patient with slightly higher effectiveness per patient (0·03 QALY) for a cost savings of $285 per QALY. Sensitivity analysis shows that TT alone offers no advantage when radioactive iodine (RAI) becomes more detrimental to a patient's state of health, when the incidence of non-neck recurrence increases above 5% in patients undergoing TT alone or decreases below 3·9% in patients undergoing TT with CND or when the rate of permanent hypocalcaemia rises above 4%. CONCLUSIONS: TT with CND is not a cost-effective strategy in low-risk PTC. Initial TT alone is favourable because of the low complication rates and low recurrence rates associated with the initial surgery. Alternative strategies such as unilateral prophylactic neck dissection require additional study to assess their cost-effectiveness.

RESUMO

BACKGROUND: There has been a notable improvement in the outcome of stage 1 palliation for hypoplastic left heart syndrome (HLHS) in recent years. Nevertheless, developing a new Norwood program requires a steep learning curve, especially in emerging economies where rapid population growth brings a high volume of patients but, on the other hand, resources are limited. In this paper we aimed to summarize the initial results of a single center. METHODS: Hospital records of 21 patients were reviewed for all patients having a stage 1 palliation procedure for HLHS between May 2011 and May 2013. There were 13 male (62%) and 8 female (38%) patients. Median age was 14 days (range, 4-74 days) and median weight was 3030 g (2600-3900 g). HLHS was defined as mitral or aortic stenosis or atresia (or both) in the presence of normally related great vessels and a hypoplastic left ventricle. Transthoracic echocardiography was the diagnostic modality used in all patients. All procedures but one were performed using an antegrade selective cerebral perfusion method and moderate hypothermia. Cerebral perfusion was monitored with cerebral oximetry in all patients. Modified ultrafiltration was routinely used in all patients. RESULTS: Overall hospital mortality was 47.6% (n = 10). Mortality rates considerably decreased from the first year to second year (69% and 12.5% respectively). No risk factors were identified for mortality. CONCLUSIONS: Surgical palliation of neonates with hypoplastic left heart syndrome continues to be a challenge. To decrease the overall mortality nationwide and improve outcomes, a referral center with a dedicated team is necessary in emerging economies.
