  • A prospective clinical study of        class="a-plus-plus">18 F-FAZA PET-CT hypoxia
           imaging in head and neck squamous cell carcinoma before and during
           radiation therapy
    • Abstract: Purpose Hypoxia in head and neck squamous cell carcinoma (HNSCC) is associated with poor prognosis and outcome. 18 F-Fluoroazomycin arabinoside (FAZA) is a positron emission tomography (PET) tracer developed to enable identification of hypoxic regions within tumor. The aim of this study was to evaluate the use of 18 F-FAZA-PET for assessment of hypoxia before and during radiation therapy. Methods Twelve patients with locally advanced HNSCC underwent 18 F-FAZA-PET scans before and at fraction 7 and 17 of concomitant chemo-radiotherapy. A hypoxic voxel was defined as a voxel expressing a standardized uptake value (SUV) equal or above the SUVmean of the posterior contralateral neck muscles plus three standard deviations. The fractional hypoxic volume fraction (FHV) and the spatial move of hypoxic volumes during treatment were analyzed. Results A hypoxic volume could be identified in ten patients before treatment. FAZA-PET FHV varied from 0 to 54.3 % and from 0 to 41.4 % in the primary tumor and in the involved node, respectively. Six out of these ten patients completed all the FAZA-PET-computed tomography (CT) during the radiotherapy. In all patients, FHV and SUVmax values decreased. All patient presented a spatial move of hypoxic volume, but only three patients had newborn hypoxic voxels after 17 fractions. Conclusion This study indicated that 18 F-FAZA-PET could be used to identify and quantify tumor hypoxia before and during concomitant radio-chemotherapy in patients with locally advanced HNSCC. In addition to the information on prognostic value, the use of 18 F-FAZA-PET allowed the delineation of hypoxic volumes for dose escalation protocols. However, due to fluctuation of hypoxia during treatment, repeated scan will have to be performed (i.e. adaptive radiotherapy).

  • HER2-positive breast cancer:        class="a-plus-plus">18F-FDG PET for early
           prediction of response to trastuzumab plus taxane-based neoadjuvant
           chemotherapy
    • Abstract: Purpose To investigate the value of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET/CT) to predict a pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in women with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Material and methods Fifty-seven consecutive women with HER2-positive breast cancer, treated with trastuzumab plus taxane-based NAC, were prospectively included. Maximum Standardized Uptake Value of the primary tumor and axillary nodes were measured at baseline (PET1.SUVmax) and after the first course of NAC (PET2.SUVmax). Tumor metabolic volumes were assessed to determine Total Lesion Glycolysis (TLG). The tumor metabolic response (ΔSUVmax and ΔTLG) was calculated. Results In univariate analysis, negative hormonal receptor status (p = 0.04), high tumor grade (p = 0.03), and low tumor PET 2 .SUVmax (p = 0.001) were predictive of pCR. Tumor ΔSUVmax correlated with pCR (p = 0.03), provided that tumors with low metabolic activity at baseline were excluded. ΔTLG did not correlate with pCR. In multivariate analysis, tumor PET2.SUVmax < 2.1 was the best independent predictive factor (Odds ratio =14.3; p = 0.004) with both negative and positive predictive values of 76 %. Although the metabolic features of the primary tumor did not depend on hormonal receptor status, both the baseline metabolism and early response of axillary nodes were higher if estrogen receptors were not expressed (p = 0.01 and p = 0.03, respectively). Conclusion In HER2-positive breast cancer, very low tumor residual metabolism after the first cycle of NAC (SUVmax < 2.1) was the main predictor of pCR. These results should be further explored in multicenter studies and incorporated into the design of clinical trials.

  • Characterizing IgG4-related disease with        class="a-plus-plus">18F-FDG PET/CT: a prospective
           cohort study
    • Abstract: Purpose IgG4-related disease (IgG4-RD) is an increasingly recognized clinicopathological disorder with immune-mediated inflammatory lesions mimicking malignancies. A cohort study was prospectively designed to investigate the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in characterizing IgG4-RD. Methods Thirty-five patients diagnosed with IgG4-RD according to the consensus criteria were enrolled with informed consent. All patients underwent baseline 18F-FDG PET/CT evaluation. Among them, 29 patients underwent a second 18F-FDG PET/CT scan after 2 to 4 weeks of steroid-based therapy. Results All 35 patients were found with 18F-FDG-avid hypermetabolic lesion(s); 97.1 % (34/35) of these patients showed multi-organ involvement. Among the 35 patients, 71.4 % (25/35) patients were found with more organ involvement on 18F-FDG PET/CT than conventional evaluations including physical examination, ultrasonography, and computed tomography (CT). 18F-FDG PET/CT demonstrated specific image characteristics and pattern of IgG4-RD, including diffusely elevated 18F-FDG uptake in the pancreas and salivary glands, patchy lesions in the retroperitoneal region and vascular wall, and multi-organ involvement that cannot be interpreted as metastasis. Comprehensive understanding of all involvement aided the biopsy-site selection in seven patients and the recanalization of ureteral obstruction in five patients. After 2 to 4 weeks of steroid-based therapy at 40 mg to 50 mg prednisone per day, 72.4 % (21/29) of the patients showed complete remission, whereas the others exhibited > 81.8 % decrease in 18F-FDG uptake. Conclusion F-FDG PET/CT is a useful tool for assessing organ involvement, monitoring therapeutic response, and guiding interventional treatment of IgG4-RD. The image pattern is suggested to be updated into the consensus diagnostic criteria for IgG4-RD.

  • Integrated 18F-FDG
           PET/perfusion CT for the monitoring of neoadjuvant chemoradiotherapy in
           rectal carcinoma: correlation with histopathology
    • Abstract: Purpose The aim of this study was to prospectively monitor changes in the flow-metabolic phenotype (ΔFMP) of rectal carcinoma (RC) after neoadjuvant chemoradiotherapy (CRT) and to evaluate whether ΔFMP of RC correlate with histopathological prognostic factors including response to CRT. Methods Sixteen patients with RC (12 men, mean age 60.7 ± 12.8 years) underwent integrated 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/perfusion CT (PET/PCT), followed by neoadjuvant CRT and surgery. In 13 patients, PET/PCT was repeated after CRT. Perfusion [blood flow (BF), blood volume (BV), mean transit time (MTT)] and metabolic [maximum and mean standardized uptake values (SUVmax, SUVmean)] parameters as well as the FMP (BF × SUVmax) were determined before and after CRT by two independent readers and correlated to histopathological prognostic factors of RC (microvessel density, necrosis index, regression index, vascular invasion) derived from resected specimens. The diagnostic performance of ΔFMP for prediction of treatment response was determined. Results FMP significantly decreased after CRT (p < 0.001), exploiting higher changes after CRT as compared to changes of perfusion and metabolic parameters alone. Before CRT, no significant correlations were found between integrated PET/PCT and any of the histopathological parameters (all p > 0.05). After CRT, BV and SUVmax correlated positively with the necrosis index (r = 0.67/0.70), SUVmax with the invasion of blood vessels (r = 0.62) and ΔFMP with the regression index (r = 0.88; all p < 0.05). ΔFMP showed high accuracy for prediction of histopathological response to CRT (AUC 0.955, 95 % confidence interval 0.833–1.000, p < 0.01) using a cut-off value of −75 %. Conclusion In RC, ΔFMP derived from integrated 18F-FDG PET/PCT is useful for monitoring the effects of neoadjuvant CRT and allows prediction of histopathological response to CRT.

  • Thyroid nodules with indeterminate cytology: molecular imaging with
                  class="a-plus-plus">99mTc-methoxyisobutylisonitrile
           (MIBI) is more cost-effective than the Afirma® gene expression
           classifier
    • Abstract: Purpose To compare the cost-effectiveness of 99mTc-methoxyisobutylisonitrile (MIBI) thyroid scintigraphy and the Afirma® gene expression classifier for the assessment of cytologically indeterminate thyroid nodules. Methods A decision tree model was used. Costs were calculated from the perspective of the German health insurance system. The robustness of the results was assessed with probabilistic sensitivity analyses using a Monte Carlo simulation. Results Life expectancy was 34.3 years (estimated costs per patient €1,459 – €2,224) for the MIBI scan and 34.1 years (estimated costs €3,560 – €4,071) for the molecular test. These results were confirmed by the Monte Carlo simulation. Conclusion MIBI thyroid scintigraphy is more cost-effective than the gene expression classifier.

  • Bispecific antibody complex pre-targeting and targeted delivery of polymer
           drug conjugates for imaging and therapy in dual human mammary cancer
           xenografts
    • Abstract: Introduction Doxorubicin, a frontline chemotherapeutic agent, limited by its cardiotoxicity and other tissue toxicities, was conjugated to N-terminal DTPA-modified polyglutamic acid (D-Dox-PGA) to produce polymer pro-drug conjugates. D-Dox-PGA or Tc-99 m labeled DTPA-succinyl-polylysine polymers (DSPL) were targeted to HER2-positive human mammary carcinoma (BT-474) in a double xenografted SCID mouse model also hosting HER2-negative human mammary carcinoma (BT-20). Methods After pretargeting with bispecific anti-HER2-affibody-anti-DTPA-Fab complexes (BAAC), anti-DTPA-Fab or only phosphate buffered saline, D-Dox-PGA or Tc-99 m DSPL were administered. Positive therapeutic control mice were injected with Dox alone at maximum tolerated dose (MTD). Results Only BT-474 lesions were visualized by gamma imaging with Tc-99 m-DSPL; BT-20 lesions were not. Therapeutic efficacy was equivalent in mice pretargeted with BAAC/targeted with D-Dox-PGA to mice treated only with doxorubicin. There was no total body weight (TBW) loss at three times the doxorubicin equivalent MTD with D-Dox-PGA, whereas mice treated with doxorubicin lost 10 % of TBW at 2 weeks and 16 % after the second MTD injection leading to death of all mice. Conclusions Our cancer imaging and pretargeted therapeutic approaches are highly target specific, delivering very high specific activity reagents that may result in the development of a novel theranostic application. HER/2 neu specific affibody-anti-DTPA-Fab bispecific antibody pretargeting of HER2 positive human mammary xenografts enabled exquisite targeting of polymers loaded with radioisotopes for molecular imaging and doxorubicin for effective therapy without the associating non-tumor normal tissue toxicities.

  • Radioimmunotherapy for first-line and relapse treatment of aggressive
           B-cell non-Hodgkin lymphoma: an analysis of 215 patients registered in the
           international RIT-Network
    • Abstract: Purpose Very few reliable clinical data about the use of radioimmunotherapy in aggressive B-cell lymphoma exist. Methods Patients with aggressive B-cell lymphoma registered in the international RIT-Network were analysed with regard to prior treatment, response and side effects. The RIT-Network is a web-based registry that collects observational data from radioimmunotherapy-treated patients with malignant lymphoma across 13 countries. Results This analysis included 215 with aggressive B-cell lymphoma out of 232 patients registered in the RIT-Network. Histological subtypes were as follows: 190 diffuse large B-cell, 15 primary mediastinal, 9 anaplastic large cell, and 1 intravascular lymphoma. The median age of the patients was 62 years (range 17 –  88), with 27 % above the age of 70 years. Radioimmunotherapy was mainly used as consolidation after first-line or second-line chemotherapy (56.1 %), as part of third-line to eighth-line therapy for relapse (16.4 %), and in refractory disease (12.2 %). Grade IV neutropenia and thrombopenia and grade III anaemia were observed. The median time to recovery of blood count was 81 days (range 0 – 600 days). The overall response rate was 63.3 %. The complete response rate was 76.4 % in patients treated as part of first-line therapy, and 44.3 % in patients with relapse. Mean overall survival in first-line therapy patients was 32.7 months and 14.0 months in patients with relapse or refractory disease, respectively. Conclusion Most patients with aggressive B-cell lymphoma in the RIT-Network received radioimmunotherapy as consolidation after first-line therapy with excellent complete remission and overall survival rates compared to published data. In relapsed aggressive B-cell lymphoma, radioimmunotherapy is a safe and feasible treatment leading to satisfactory response rates with acceptable toxicity.

  • 18F-FDG uptake as a
           prognostic variable in primary differentiated thyroid cancer incidentally
           detected by PET/CT: a multicentre study
    • Abstract: Purpose Our aim was to investigate the association between 18F-fluorodeoxyglucose (FDG) uptake and event-free survival in patients in whom a differentiated thyroid cancer (DTC) was detected by 18F-FDG positron emission tomography (PET)/CT. Methods Among 884 focal 18F-FDG PET thyroid incidentalomas referred to our 4 Nuclear Medicine Departments, we investigated 54 patients in whom a DTC was confirmed and a clinical follow-up was available. The ratio between maximum standardized uptake value (SUVmax) of DTC and SUVmean of the liver (SUV ratio) was recorded for each scan. All patients underwent total thyroidectomy and 131I remnant ablation. After a median follow-up of 39 months we assessed the outcome. The association between disease persistence/progression, 18F-FDG uptake and other risk factors (T, N, M and histological subtype) was evaluated through univariate and multivariate analyses. Results Of the 54 patients, 39 achieved complete remission. The remaining 15 showed persistence/progression of disease. High 18F-FDG uptake, i.e. SUV ratio ≥3, showed a low positive predictive value (48 %). Low 18F-FDG uptake (SUV ratio < 3) displayed a high negative predictive value (93 %). The median of SUV ratios in T1–T2 (2.2), in M0 (2.7) and in non-virulent subtypes (2.7) were significantly lower (p < 0.03) than in T3–T4 (5.0), M1 (7.3) and virulent subtypes (6.0). Kaplan-Maier analysis showed a significant association between high 18F-FDG uptake and disease persistence/progression (p = 0.001). When we adjusted risk estimates by using a multivariate Cox model, only T (p = 0.05) remained independently associated with disease persistence/progression. Conclusion An intense 18F-FDG uptake of the primary DTC is associated with persistence/progression of disease. However, when all other prognostic factors have been taken into account, 18F-FDG uptake does not add further prognostic information.

  • Role of 18F-FDG
           PET/CT in the diagnosis of infective endocarditis in patients with an
           implanted cardiac device: a prospective study
    • Abstract: Purpose Infective endocarditis (IE) is widely underdiagnosed or diagnosed after a major delay. The diagnosis is currently based on the modified DUKE criteria, where the only validated imaging technique is echocardiography, and remains challenging especially in patients with an implantable cardiac device. The aim of this study was to assess the incremental diagnostic role of 18F-FDG PET/CT in patients with an implanted cardiac device and suspected IE. Methods We prospectively analysed 27 consecutive patients with an implantable device evaluated for suspected device-related IE between January 2011 and June 2013. The diagnostic probability of IE was defined at presentation according to the modified DUKE criteria. PET/CT was performed as soon as possible following the clinical suspicion of IE. Patients then underwent medical or surgical treatment based on the overall clinical evaluation. During follow-up, we considered: lead cultures in patients who underwent extraction, direct inspection and lead cultures in those who underwent surgery, and a clinical/instrumental reevaluation after at least 6 months in patients who received antimicrobial treatment or had an alternative diagnosis and were not treated for IE. After the follow-up period, the diagnosis was systematically reviewed by the multidisciplinary team using the modified DUKE criteria and considering the new findings. Results Among the ten patients with a positive PET/CT scan, seven received a final diagnosis of “definite IE”, one of “possible IE” and two of “IE rejected”. Among the 17 patients with a negative PET/CT scan, four were false-negative and received a final diagnosis of definite IE. These patients underwent PET/CT after having started antibiotic therapy (≥48 h) or had a technically suboptimal examination. Conclusion In patients with a cardiac device, PET/CT increases the diagnostic accuracy of the modified Duke criteria for IE, particularly in the subset of patients with possible IE in whom it may help the clinician manage a challenging situation.

  • Nuclear medicine training and practice in the Czech Republic
    • Abstract: Abstract Nuclear medicine in the Czech Republic is a full specialty with an exclusive practice. Since the training program was organized and structured in recent years, residents have had access to the specialty of nuclear medicine, starting with a two-year general internship (in internal medicine or radiology). At present, nuclear medicine services are provided in 45 departments. In total, 119 nuclear medicine specialists are currently registered. In order to obtain the title of Nuclear Medicine Specialist, five years of training are necessary; the first two years consist of a general internship in internal medicine or radiology. The remaining three years consist of training in the nuclear medicine specialty itself, but includes three months of practice in radiology. Twenty-one physicians are currently in nuclear medicine training and a mean of three specialists pass the final exam per year. The syllabus is very similar to that of the European Union of Medical Specialists (UEMS), namely concerning the minimum recommended numbers for diagnostic and therapeutic procedures. In principle, the Czech law requires continuous medical education for all practicing doctors. The Czech Medical Chamber has provided a continuing medical education (CME) system. Other national CMEs are not accepted in Czech Republic.
