RESUMO
BACKGROUND: Unnecessary D2-gastrectomy and associated costs can be prevented after detecting non-curable gastric cancer, but impact of staging on treatment costs is unclear. This study determined the cost impact of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18FFDG-PET/CT) and staging laparoscopy (SL) in gastric cancer staging. MATERIALS AND METHODS: In this cost analysis, four staging strategies were modeled in a decision tree: (1) 18FFDG-PET/CT first, then SL, (2) SL only, (3) 18FFDG-PET/CT only, and (4) neither SL nor 18FFDG-PET/CT. Costs were assessed on the basis of the prospective PLASTIC-study, which evaluated adding 18FFDG-PET/CT and SL to staging advanced gastric cancer (cT3-4 and/or cN+) in 18 Dutch hospitals. The Dutch Healthcare Authority provided 18FFDG-PET/CT unit costs. SL unit costs were calculated bottom-up. Gastrectomy-associated costs were collected with hospital claim data until 30 days postoperatively. Uncertainty was assessed in a probabilistic sensitivity analysis (1000 iterations). RESULTS: 18FFDG-PET/CT costs were 1104 including biopsy/cytology. Bottom-up calculations totaled 1537 per SL. D2-gastrectomy costs were 19,308. Total costs per patient were 18,137 for strategy 1, 17,079 for strategy 2, and 19,805 for strategy 3. If all patients undergo gastrectomy, total costs were 18,959 per patient (strategy 4). Performing SL only reduced costs by 1880 per patient. Adding 18FFDG-PET/CT to SL increased costs by 1058 per patient; IQR 870-1253 in the sensitivity analysis. CONCLUSIONS: For advanced gastric cancer, performing SL resulted in substantial cost savings by reducing unnecessary gastrectomies. In contrast, routine 18FFDG-PET/CT increased costs without substantially reducing unnecessary gastrectomies, and is not recommended due to limited impact with major costs. TRIAL REGISTRATION: NCT03208621. This trial was registered prospectively on 30-06-2017.

OBJECTIVE: The radiopharmaceuticals radium-223 and the pharmacy preparation 177Lu-PSMA-I&T are reimbursed in the Netherlands for metastatic castration-resistant prostate cancer (mCRPC) treatment. Although shown to be life-prolonging in patients with mCRPC, the treatment procedures associated with these radiopharmaceuticals can be challenging for both patients and hospitals. This study investigates the costs of mCRPC treatment in Dutch hospitals for currently reimbursed radiopharmaceuticals with a demonstrated overall survival benefit. METHODS: A cost model that calculated the direct medical per-patient costs of radium-223 and 177Lu-PSMA-I&T was developed, following clinical trial regimens. The model considered six 4-weekly administrations (i.e. ALSYMPCA regimen) of radium-223. Regarding 177Lu-PSMA-I&T, the model used both the VISION regimen (i.e. five 6-weekly administrations) and the SPLASH regimen (i.e. four 8-weekly administrations). Based on health insurance claims, we also estimated the coverage a hospital would receive for providing treatment. No fitting health insurance claim for 177Lu-PSMA-I&T is currently available; therefore, we calculated a break-even value for a potential health insurance claim that would exactly counterbalance the per-patient costs and coverage. RESULTS: Radium-223 administration is associated with per-patient costs of 30,905, and these costs are fully covered by the coverage a hospital receives. The per-patient costs of 177Lu-PSMA-I&T range between 35,866 and 47,546 per administration period, depending on the regimen. Current healthcare insurance claims do not fully cover the costs of providing 177Lu-PSMA-I&T: hospitals must pay 4,414-4,922 for each patient out of their own budget. The break-even value for the potential insurance claim covering 177Lu-PSMA-I&T administration with a VISION (SPLASH) regimen is 1,073 (1,215). CONCLUSION: This study shows that, without consideration of the treatment effect, radium-223 treatment for mCRPC leads to lower per-patient costs than treatment with 177Lu-PSMA-I&T. The detailed overview of the costs associated with radiopharmaceutical treatment provided by this study is relevant for both hospitals and healthcare insurers.
Prostate cancer is the most common form of cancer among men in the Netherlands, and its treatment is increasingly expensive. Given the limited hospital budget, it is important to consider costs in the treatment of prostate cancer. Radiopharmaceuticals are one of the multiple treatment options for metastatic prostate cancer. The current study looked at the costs of two radiopharmaceuticals, radium-223 and 177Lu-PSMA-I&T, while using multiple treatment regimens.The cost of radium-223 treatment is 30,905 per patient and is fully covered by insurance. The cost of 177Lu-PSMA-I&T treatment ranges from 35,866 to 47,546 per patient and is partially paid from the budget of the hospitals considering current reimbursement amounts. The study shows that, without consideration of the treatment effects, radium-223 treatment for prostate cancer leads to lower per-patient costs than treatment with 177Lu-PSMA-I&T. The detailed overview of the costs associated with radiopharmaceutical treatment provided by this study is relevant for both hospitals and healthcare insurers to manage prostate cancer treatment costs.

BACKGROUND: Primary hyperparathyroidism historically necessitated bilateral neck exploration to remove abnormal parathyroid tissue. Improved localization allows for focused parathyroidectomy with lower complication risks. Recently, positron emission tomography using radiolabeled 18F-fluorocholine demonstrated high accuracy in detecting these lesions, but its cost-effectiveness has not been studied in the United States. METHODS: A decision tree modeled patients who underwent parathyroidectomy for primary hyperparathyroidism using single preoperative localization modalities: (1) positron emission tomography using radiolabeled 18F-fluorocholine, (2) 4-dimensional computed tomography, (3) ultrasound, and (4) sestamibi single photon emission computed tomography (SPECT). All patients underwent either focused parathyroidectomy versus bilateral neck exploration, with associated cost ($) and clinical outcomes measured in quality-adjusted life-years gained. Model parameters were informed by literature review and Medicare costs. Incremental cost-utility ratios were calculated in US dollars/quality-adjusted life-years gained, with a willingness-to-pay threshold set at $100,000/quality-adjusted life-year. One-way, 2-way, and threshold sensitivity analyses were performed. RESULTS: Positron emission tomography using radiolabeled 18F-fluorocholine gained the most quality-adjusted life-years (23.9) and was the costliest ($2,096), with a total treatment cost of $11,245 or $470/quality-adjusted life-year gained. Sestamibi single photon emission computed tomography and ultrasound were dominated strategies. Compared with 4-dimentional computed tomography, the incremental cost-utility ratio for positron emission tomography using radiolabeled 18F-fluorocholine was $91,066/quality-adjusted life-year gained in our base case analysis, which was below the willingness-to-pay threshold. In 1-way sensitivity analysis, the incremental cost-utility ratio was sensitive to test accuracy, positron emission tomography using radiolabeled 18F-fluorocholine price, postoperative complication probabilities, proportion of bilateral neck exploration patients needing overnight hospitalization, and life expectancy. CONCLUSION: Our model elucidates scenarios in which positron emission tomography using radiolabeled 18F-fluorocholine can potentially be a cost-effective imaging option for primary hyperparathyroidism in the United States. Further investigation is needed to determine the maximal cost-effectiveness for positron emission tomography using radiolabeled 18F-fluorocholine in selected populations.

BACKGROUND: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) represent a heterogenous group of tumors. Findings from the phase III NETTER-1 trial showed that treatment of unresectable/metastatic progressive gastrointestinal (GI) NETs with 177Lu-Dotatate resulted in a significant improvement in progression-free survival (PFS) and overall survival (OS) compared with best supportive care (BSC) with high dose octreotide long-acting repeatable (LAR) 60 mg. A health economic analysis was performed using input data from clinical studies and data derived from an indirect comparison to determine the cost-effectiveness of 177Lu-Dotatate in the treatment of GI-NETs and pancreatic NETs (P-NETs) in Scotland. METHODS: Cost-effectiveness analysis was performed from the payer perspective using a three-state partitioned survival model. In the base case 177Lu-Dotatate was compared with BSC in gastrointestinal (GI)-NETs using clinical data from the NETTER-1 trial. A secondary analysis comparing 177Lu-Dotatate with BSC, everolimus or sunitinib in patients with P-NETs was also performed using hazard ratios inferred from indirect comparisons. The base case analysis was performed over a 20-year time horizon with an annual discount rate of 3.5% for both costs and clinical outcomes. RESULTS: For unresectable/metastatic progressive GI-NETs treatment with 177Lu-Dotatate led to a gain in quality-adjusted life expectancy of 1.33 quality-adjusted life years (QALYs) compared with BSC due to extended PFS and OS. Mean total lifetime costs were GBP 35,701 higher with 177Lu-Dotatate, leading to an incremental cost-effectiveness ratio (ICER) of GBP 26,830 per QALY gained. In analyses in patients with P-NETs 177Lu-Dotatate was associated with ICERs below GBP 30,000 per QALY gained in comparisons with BSC, sunitinib and everolimus. CONCLUSIONS: Cost-effectiveness analyses demonstrated that, in Scotland, from the payer perspective, 177Lu-Dotatate at the set acquisition cost is a cost-effective treatment option for patients with unresectable or metastatic progressive GI-NETs or P-NETs.

Nuclear medicine has come a long way since 2007 when Adrian Nunn pointed out the approval of radiopharmaceuticals was at an all-time low with all the major radiopharmaceutical agents in use having been approved over 10 years ago. Challenges being the prohibitively high cost of drug development and the large number of drugs failing in clinical trials. Proceed to today where molecular imaging is fast-tracking the drug discovery process by reducing both the time and cost to screen candidates by quantitating the drugs effect on the target and toxicity to normal tissues. Nuclear medicine is now leading medical practice in personalized medicine using the theragnostic approach. Theragnostics is defined as the use of molecular diagnostic techniques in real time to stratify patients to guide treatment decisions such as the choice of drug, the dose of administration, and the timing of drug delivery for a given patient. Enabling visualization and quantitation of in vivo function of the whole body and thus patient heterogeneity and variability informs the physician on how to treat an individual patient. Recent successes such as the Food and Drug Administration approval of Lutathera and NETSPOT have resulted in an increasing number of pharmaceutical companies pursing theragnostics further heightened by the purchase of Advanced Accelerator Applications for 3.9 billion by Novartis and Endocyte, Inc for 2.1 billion. Theragnostics are further aiding drug development by showing which agents are most viable and reducing the overall cost of bringing a drug to clinical trials and regulatory approval. This is indeed a renaissance for nuclear medicine in which the acceptance of imaging to inform and monitor therapy has been embraced and even required by the Food and Drug Administration for the clinical evaluation of targeted therapeutic radiopharmaceuticals showing there is indeed a viable business model for targeted theragnostic radiopharmaceuticals and personalized medicine.

Until recently, it has been challenging to engage Wall Street and large pharmaceutical companies in radiopharmaceutical opportunities. The modest economic prospects of most diagnostic radiopharmaceuticals have not attracted keen interest from the broader business community, despite the rapid advancement of diagnostic imaging capabilities and their increasingly crucial role in the therapeutic process. Similarly, compelling science supporting select radiopharmaceutical therapies in oncology has been overshadowed by the unique challenges posed by this class of drugs and historical commercial failures that serve as sobering reminders of risk. Fortunately, a few notable successes in the targeted radioligand therapeutic space are changing this dynamic, fueling a new flow of investor capital into these technologies and inciting increased merger and acquisition activity that has yielded significant value creation for investors. If the nuclear medicine industry is able to continue to effectively manage historical challenges, then there is significant opportunity for a new and promising wave of radioligand therapies to significantly change the oncology treatment paradigm and elevate the profile of the entire nuclear medicine sector.

PURPOSE: To analyze the cost-effectiveness of radioembolization in the treatment of intrahepatic cholangiocarcinoma (ICC) using the Surveillance, Epidemiology, and End Results (SEER) Medicare cancer database. MATERIALS AND METHODS: Cost as measured by total treatment-related reimbursement in patients diagnosed with ICC who received chemotherapy alone or chemotherapy and yttrium-90 radioembolization was assessed in the SEER Medicare cancer database (1999-2012). Survival analysis was performed, and incremental cost-effectiveness ratios were generated. RESULTS: The study included 585 patients. Average age at diagnosis was 71 years (standard deviation: 9.9), and 52% of patients were male. Twelve percent of patients received chemotherapy with radioembolization (n = 72), and 88% of patients (n = 513) received only chemotherapy. Median survival was 1043 days (95% confidence interval [CI]: 894-1244) for chemotherapy plus radioembolization and 811 days (95% CI: 705-925) for chemotherapy alone (P = .02). Patients who received combination therapy were slightly younger (71 vs 69 years, P = .03). No significant differences were observed between treatment groups in age at treatment, sex, race, or city size. Multivariable analysis showed a hazard ratio for progression for combination therapy versus chemotherapy alone of 0.76 (95% CI: 0.59-0.97, P = .029). The incremental cost-effectiveness ratio, a measure of cost of each added year of life, was $50,058.65 per year (quartiles: $11,454.63, $52,763.28). CONCLUSIONS: Combination therapy of ICC with chemotherapy and radioembolization is associated with higher median survival and can be a cost-effective treatment, with a median cost of $50,058.65 per additional year of survival.

BACKGROUND/AIMS: The role of [18F]-f luorodeoxyglucose positron emission tomography-computed tomography (PET/CT) in patients with diffuse large B-cell lymphoma (DLBCL) in first remission is unclear. METHODS: Medical costs within the first 3 years of treatment completion and clinical outcomes of 118 patients with DLBCL in first remission with and without surveillance PET/CT (PET/CT [+] group [n = 76] and PET/CT [-] group [n = 42], respectively) were retrospectively analyzed. RESULTS: In a propensity matched cohort with adjustment for International Prognostic Index risk and relapse, the PET/CT (+) group was shown to have similar medical costs as the PET/CT (-) group. Relapse-free survival (RFS) and overall survival (OS) were comparable between the two groups (median RFS not reached [NR] for both groups, p = 0.133; median OS NR, p = 0.542). Among 76 patients with surveillance PET/CT, 31 (40.8%) had findings suggestive of recurrence and 16 of these (51.6%) were later confirmed to have recurrent disease. Fifteen patients (48.4%) were confirmed to not have recurrence after follow-up CT or PET/CT evaluation (n = 10) and biopsy (n = 4). None of the patients with negative PET/CT findings had disease recurrence. Sensitivity, specificity, positive predictive value, and negative predictive value of PET/CT for detection of recurrence were 1, 0.75, 0.52, and 1, respectively. CONCLUSION: Surveillance PET/CT resulted in similar clinical outcomes and medical costs compared to no surveillance PET/CT. Approximately half of patients with PET/CT findings of recurrence had no recurrence after follow-up imaging and biopsy, which would not have been carried out if PET/CT had not been performed in the first place.

INTRODUCTION: Between 2009 and 2012, 68 Ga-somatostatin analogue PET-CT progressively replaced 111 In-octreotide scintigraphy for imaging neuroendocrine tumours in WA public hospitals due to published literature demonstrating improved diagnostic accuracy and increased availability. Despite significantly improved sensitivity and specificity, 68 Ga-somatostatin analogue PET is currently unfunded in Australia. This study sought to undertake cost analysis of the two modalities in a public hospital setting and to compare them with regard to patient factors such as imaging time and radiation dose. METHODS: This analysis was based on retrospective clinical data from 95 111 In-octreotide scintigraphies performed in 2007 and 2008 at Sir Charles Gairdner (SCGH) and Royal Perth (RPH) hospitals and 219 68 Ga-somatostatin analogue PET-CT studies performed in 2013 at SCGH. Whole body effective radiation dose was derived from the radiopharmaceutical and low-dose CT scan. The cost analysis included radiopharmaceutical and imaging costs. RESULTS: The median imaging time for an 111 In-octreotide scintigraphy was 152 min at SCGH, 100 min at RPH and 20 min for a 68 Ga-somatostatin analogue PET-CT scan. The mean effective radiation dose for 111 In-octreotide scintigraphy was 18.1 mSv at SCGH and 13.8 mSv at RPH. The effective dose for 68 Ga-somatostatin analogue PET-CT was 8.7-10.8 mSv. The average cost of 68 Ga-somatostatin analogue PET-CT was four times less than 111 In-octreotide scintigraphy. CONCLUSION: 68 Ga-somatostatin analogue PET-CT is not only more accurate than 111 In-octreotide scintigraphy, this study has also shown that it is significantly less expensive, delivers a lower radiation dose to patients and requires less imaging time for patients and staff. 68 Ga-somatostatin PET-CT provides an important combination of both reduced cost and improved clinical care for patients.

BACKGROUND: Technetium-99m dimercaptosuccinic acid (DMSA) scans are often used in the evaluation of pediatric patients with febrile urinary tract infections (UTIs). Given the prevalence of febrile UTIs, we sought to quantify the cost, radiation exposure, and clinical utility of DMSA scans when compared with dedicated pediatric renal ultrasounds (RUSs). MATERIALS AND METHODS: An institutional review board approved retrospective study of children under the age of 18 years evaluated at our institution for febrile UTIs between the years 2004-2013 was conducted. The patients had to meet all of the following inclusion criteria: a diagnosis of vesicoureteral reflux, a fever >38°C, a positive urine culture, and evaluation with a DMSA scan and RUS. A chart review was used to construct a cost analysis of technical and professional fees, radiographic results, and radiation dose equivalents. RESULTS: Overall, 104 children met the inclusion criteria. A total of 122 RUS and 135 DMSA scans were performed. The technical costs of a DMSA scan incurred a 35% cost premium as compared to an RUS. The average effective radiation dose of a single DMSA scan was 2.84 mSv. New radiographic findings were only identified on 7% of those patients who underwent greater than 1 DMSA scan. CONCLUSIONS: The utility of the unique information acquired from a DMSA scan as compared to a RUS in the evaluation of febrile UTI must be evaluated on an individual case-by-case basis given the increased direct costs and radiation exposure to the patient.

OBJECTIVE: The purpose of this study was to examine additional diagnostic workup and costs generated by addition of a single molecular breast imaging (MBI) examination to screening mammography for women with dense breasts. SUBJECTS AND METHODS: Women with mammographically dense breasts presenting for screening mammography underwent adjunct MBI performed with 300 MBq (99m)Tc-sestamibi and a direct-conversion cadmium-zinc-telluride dual-head gamma camera. All subsequent imaging tests and biopsies were tracked for a minimum of 1 year. The positive predictive value of biopsies performed (PPV3), benign biopsy rate, cost per patient screened, and cost per cancer detected were determined. RESULTS: A total of 1651 women enrolled in the study. Among the 1585 participants with complete reference standard, screening mammography alone prompted diagnostic workup of 175 (11.0%) patients and biopsy of 20 (1.3%) and yielded five malignancies (PPV3, 25%). Results of combined screening mammography plus MBI prompted diagnostic workup of 279 patients (17.6%) and biopsy of 67 (4.2%) and yielded 19 malignancies (PPV3, 28.4%). The benign biopsy rates were 0.9% (15 of 1585) for screening mammography alone and 3.0% (48 of 1585) for the combination (p < 0.001). The addition of MBI increased the cost per patient screened from $176 for mammography alone to $571 for the combination. However, cost per cancer detected was lower for the combination ($47,597) than for mammography alone ($55,851). CONCLUSION: The addition of MBI to screening mammography of women with dense breasts increased the overall costs and benign biopsy rate but also increased the cancer detection rate, which resulted in a lower cost per cancer detected than with screening mammography alone.

PURPOSE: Surveillance imaging of asymptomatic patients with diffuse large B-cell lymphoma (DLBCL) in first remission remains controversial. A decision-analytic Markov model was developed to evaluate the cost-effectiveness of follow-up strategies following first-line immunochemotherapy. PATIENTS AND METHODS: Three strategies were compared in 55-year-old patient cohorts: routine clinical follow-up without serial imaging, routine follow-up with biannual computed tomography (CT) scans for 2 years, or routine follow-up with biannual [(18)F]-fluorodeoxyglucose positron emission tomography-computed tomography (PET/CT) for 2 years. The baseline model favored imaging-based strategies by associating asymptomatic imaging-detected relapses with improved clinical outcomes. Lifetime costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated for each surveillance strategy. RESULTS: Surveillance strategies utilizing 2 years of routine CT or PET/CT scans were associated with minimal survival benefit when compared with clinical follow-up without routine imaging (life-years gained: CT, 0.03 years; PET/CT, 0.04 years). The benefit of imaging-based follow-up remained small after quality-of-life adjustments (CT, 0.020 QALYs; PET/CT, 0.025 QALYs). Costs associated with imaging-based surveillance strategies are considerable; ICERs for imaging strategies compared with clinical follow-up were $164,960/QALY (95% CI, $116,510 to $766,930/QALY) and $168,750/QALY (95% CI, $117,440 to 853,550/QALY) for CT and PET/CT, respectively. Model conclusions were robust and remained stable on one-way and probabilistic sensitivity analyses. CONCLUSION: Our cost-effectiveness analysis suggests surveillance imaging of asymptomatic DLBCL patients in remission offers little clinical benefit at substantial economic costs.

The development of clinical diagnostic procedures comprises early-phase and late-phase studies to elucidate diagnostic accuracy and patient outcome. Economic assessments of new diagnostic procedures compared with established work-ups indicate additional cost for 1 additional unit of effectiveness measure by means of incremental cost-effectiveness ratios when considering the replacement of the standard regimen by a new diagnostic procedure. This article discusses economic assessments of PET and PET/computed tomography reported until mid-July 2014. Forty-seven studies on cancer and noncancer indications were identified but, because of the widely varying scope of the analyses, a substantial amount of work remains to be done.

OBJECTIVE: Estimating the cost-effectiveness of 18FDG-PET/CT (positron emission tomography) compared to computer tomography (CT) followed by 18FDG-PET/CT as a confirmatory test for a positive case at the end of treatment in Hodgkin's lymphoma (HL) patients under 18 years-old. METHODS: A decision tree was built for comparing 18FDG-PET/CT to CT followed by 18FDG-PET/CT as a confirmatory test for a positive case in detecting residual lesions; outcome was measured in life years gained (LYG). The cost-effectiveness ratio was calculated; the threshold was 3 times the per capita GDP per LYG. Values were expressed in Colombian pesos for 2010 (1 US dollar=$ 1,897.89) and submitted to deterministic and probabilistic sensitivity analysis. RESULTS: Assuming a difference of 13 months in true positives' life expectancy compared to that for false negatives, the cost of an additional LYG with 18FDG-PET/CT compared to CT followed by 18FDG-PET/CT as a confirmatory test for a positive case when evaluating the end of pediatric HL patients' treatment was $ 34,508,590 (COP). CONCLUSION: If differential life-expectancy between true positives and false negatives is at least 1.03 years, then using 18FDG-PET/CT for evaluating the end of HL pediatric patients' therapy is a cost-effective strategy for Colombia.

PURPOSE: To assess cost effectiveness of radioembolization versus conventional transarterial chemoembolization. MATERIALS AND METHODS: The cost of radioembolization versus conventional transarterial chemoembolization was determined based on Medicare reimbursements. Three patient subgroups were defined based on the Barcelona Clinic Liver Cancer (BCLC) classification system (A, B, or C). Efficacy and safety outcomes after each procedure were obtained from the literature. A Monte Carlo case-based simulation was designed for 60 months in 250 patients in each subgroup. Survival was calculated based on average survival from the literature and the Monte Carlo model. The primary outcome was the cost effectiveness of radioembolization over transarterial chemoembolization by considering calculated survival. RESULTS: The costs approached $17,000 for transarterial chemoembolization versus $31,000 or $48,000 for unilobar or bilobar radioembolization, respectively. Based on the simulation, median estimated survival was greater with transarterial chemoembolization than radioembolization in BCLC-A and BCLC-B subgroups (40 months vs 30 months and 23 months vs 16 months, respectively, P = .001). However, in the BCLC-C subgroup, survival was greater with radioembolization than transarterial chemoembolization (13 months vs 17 months, P = .001). The incremental cost-effectiveness ratio of radioembolization over transarterial chemoembolization in the BCLC-C subgroup was $360 per month. The results were dependent on bilobar versus unilobar radioembolization and the total number of radioembolization procedures. CONCLUSIONS: The model suggests radioembolization costs may be justified for patients with BCLC-C disease, whereas radioembolization may not be cost effective in patients with BCLC-A disease; however, many patients with BCLC-C disease have extensive disease precluding locoregional therapies. Secondary considerations may determine treatment choice in more borderline patients (BCLC-B disease) because there is no persistent survival benefit with radioembolization.

BACKGROUND: Both MRI and breast-specific gamma imaging are tools for surgical planning in newly diagnosed breast cancer. Breast-specific gamma imaging (BSGI) is used less frequently although it is of similar utility and lower cost. We compared the diagnostic and cost efficacy of BSGI with MRI. METHODS: Retrospective review of 1,480 BSGIs was performed in a community breast health center, 539 had a new diagnosis of cancer, 75 patients having both MRI and BSGI performed within 2 months of each other. Institutional charges for BSGI ($850) and MRI ($3,381) were noted. RESULTS: BSGI had a sensitivity of 92%, specificity of 73%, positive predictive value of 78%, and negative predictive value of 90%. This compared favorably with MRI that had sensitivity of 89%, specificity 54%, positive predictive value 67%, and negative predictive value 83%. The accuracy of BSGI was higher at 82% vs MRI at 72%. Total cost of MRI imaging was $253,575 vs BSGI at $63,750. CONCLUSIONS: BSGI is a cost-effective and accurate imaging study for further evaluation of dense breast tissue and new diagnosis of cancer.

BACKGROUND: We examined the ability of a procalcitonin (PCT) protocol to detect vesicoureteral reflux (VUR) and renal scarring (RS), evaluated procedural costs and radiation burden, and compared four representative guidelines for children with their first febrile urinary tract infection (UTI). METHODS: Children aged ≤2 years with their first febrile UTI who underwent renal ultrasonography (US), acute and late technetium-99m ((99m)Tc)-dimercaptosuccinic acid scan, and voiding cystourethrography were prospectively studied. The representative guidelines applied in a retrospective simulation included the American Academy of Pediatrics (AAP), National Institute of Clinical Excellence, top-down approach (TDA), and Italian Society of Pediatric Nephrology (ISPN). These were compared in terms of ability to detect abnormalities, procedural costs and radiation. RESULTS: Of 278 children analyzed, 172 (61.9%) had acute pyelonephritis. There was VUR in 101 (36.3%) children, including 73 (26.3%) with grades III-V VUR. RS was identified in 75 (27.0%) children. To detect VUR, TDA and PCT had the highest sensitivity for grades I-V VUR (80.2%) and III-V VUR (94.5%), respectively, whereas AAP had the highest specificity for I-V VUR (77.4%) and III-V VUR (78.0%), respectively. TDA and PCT had the highest sensitivity (100%) for detecting RS. The highest cost and radiation dose was associated with TDA, whereas AAP had the least expenditure and radiation exposure. By multivariate analysis, PCT and VUR, especially grades III-V, were independent predictors of RS. CONCLUSIONS: There is no perfect guideline for first febrile UTI children. The PCT protocol has good ability for detecting high-grade VUR and RS. If based on available imaging modalities and reducing cost and radiation burden, clinical suggestions in the AAP guidelines represent a considerable protocol.

Objetivo Estimar la costo-efectividad de 18FDG-PET/CT comparado con CT seguido de 18FDG-PET/CT como prueba confirmatoria de un caso positivo en la evaluación al final del tratamiento en pacientes menores de 18 años con Linfoma Hodgkin (LH). Métodos Se construyó un árbol de decisión donde se comparó el uso de 18FDG-PET/CT con CT seguido de 18FDG-PET/CT como prueba confirmatoria de un caso positivo en la detección de lesión residual. El resultado se midió en Años de Vida Ganados (AVG). Se calculó la razón de costo-efectividad incremental. Se utilizó como umbral 3 veces el PIB per cápita por año AVG. Valores expresados en pesos colombianos de 2010 (1 US dólar = $ 1 897,89) Se realizaron análisis de sensibilidad univariados, bivariados y probabilísticos. Resultados Suponiendo un diferencial en AVG entre verdaderos positivos y falsos negativos de 13 meses, el costo de un AVG adicional con 18FDG-PET/CT comparado con CT seguido de 18FDG-PET/CT como prueba confirmatoria de un caso positivo en la evaluación al final del tratamiento en pacientes pediátricos con LH fue $ 34 508 590. Conclusión Si el diferencial de esperanza de vida entre verdaderos positivos y falsos negativos es de al menos un 1,03 años, el uso de 18FDG-PET/CT en la evaluación al final del tratamiento de pacientes pediátricos con LH, es una estrategia costo-efectiva para Colombia.
