8535 Background: US-guided-FNAC prior to surgical SN staging is emerging as a possible cost-effective addition to the staging of melanoma patients (pts). Formerly, sensitivity (sens) rates of lymph node US in melanoma were disappointing (20–40%). The introduction of the Berlin Morphology Criteria has significantly improved sens rates for US-FNAC (J Clin Oncol 2010;28(5):847-52). The aim of the current study was to report on 1000 patients the sens, specificity (spec), positive (PPV) and negative (NPV) predictive value rates of US-FNAC from our prospective database with prolonged follow-up. Methods: Since 2001, >1000 stage I / II consecutive melanoma pts have undergone US-FNAC prior to SN. All patients underwent lymphoscintigraphy. Peripheral Perfusion (PP), Loss of Central Echoes (LCE), Balloon Shaped (BS) were the Berlin Morphology Criteria which were registered. FNAC was performed in case of presence of any of these factors. SN tumor burden was measured according to the Rotterdam Criteria. All patients underwent SN or LND in case of positive FNAC. Results: Mean/median Breslow thickness was 2.56 / 1.57 mm (0.2 – 44 mm).Mean/median follow-up was 39 / 32 months (0 – 115). Ulceration was present in 24 %. SN positivity rates were 20 % (202 / 1000). Sens was 51 %. Spec, PPV and NPV were 99%, 91% and 89%. Sensitivity was highest for T4 tumors (77%). PP, LCE, BS had sens of 69%, 24%, 25%. SN tumor burden > 1 mm in largest diameter according to the Rotterdam Criteria was identified by US-FNAC in 86%. Threshold for positive FNAC was 0.4 mm in maximum diameter. Conclusions: The new criterion of Periferal Perfusion is of key importance to achieve the high sensitivity of US-FNAC according to the Berlin Morphology Criteria (J Clin Oncol 2010; 28:847-852) to identify lymph node metastases. Especially for T4 patients and in patients with advanced SN tumor burden it can reduce significantly the need for surgical SN staging. The EORTC Melanoma Group will launch the prospective validation study, USE FNAC, in 2012.

Abstract Introduction: Thyroglobulin evaluation in the washout of fine-needle aspiration (FNA-Tg) is an accurate diagnostic method of lymph node metastases (LNM) of differentiated thyroid carcinoma (DTC). Serum anti-thyroglobulin antibodies (AATg) may cause falsely low serum Tg values, but their effect on FNA-Tg has not been well established. There are also concerns about the possibility that suppressed TSH results in false-negative FNA-Tg. Our objectives were to evaluate the effect of serum AATg and TSH level on FNA-Tg of LNM of DTC and to determine the presence of AATg on the washout of fine needle aspiration (FNA-AATg). Methods: Retrospective analysis of patients who underwent FNA-Tg assay in LNM of DTC. The sample was divided in two groups according to the presence of serum AATg at the time of FNA-Tg evaluation (Group 1: positive AATg, n =47; Group 2: negative AATg, n =50). Results: There was no significant difference in the FNA-Tg between the two groups ( p =0.066), although it was lower in Group 1 (1428 ng/mL) than in Group 2 (14842 ng/mL). FNA-Tg was able to identify 10.3% LNM of DTC that would not be diagnosed based solely on cytology. FNA-AATg evaluation was positive in 12.8% of the Group 1 patients and did not seem to interfere with FNA-Tg value ( p =0.732). There were no differences in the median FNA-Tg measurements between those on levothyroxine suppressive therapy and those on substitutive therapy ( p =0.800). Conclusion: FNA-Tg assay appears to be a good diagnostic tool even in patients with positive serum AATg and those under suppressive levothyroxine therapy.

PURPOSE: To prospectively compare positron emission tomography (PET) imaging of regional lymph node basins to sentinel node biopsy (SNB) in patients with American Joint Committee on Cancer (AJCC) stage I, II, and III melanoma localized to the skin. METHODS: Patients with cutaneous melanoma with Breslow's depth greater than 1 mm (AJCC T2-4N0M0) or localized regional cutaneous recurrence (TxN2bM0) underwent whole-body imaging of glucose metabolism with fluorodeoxyglucose (FDG) PET followed by SNB. PET scans were interpreted in a blinded fashion and compared with histologic analyses of SNB specimens and clinical follow-up examination. Nodal tumor volumes were estimated. RESULTS: Eighty-nine lymph node basins were evaluated by FDG-PET and SNB in 70 assessable patients. Eighteen patients (25.7%) had lymph node metastases at the time of FDG-PET imaging: 17 proved by SNB (24.3%) and one by follow-up examination (1.4%). Median tumor volume in positive sentinel node basins was 4.3 mm3 (range, 0.07 to 523 mm3). Sensitivity of SNB for detection of occult regional lymph node metastases was 94.4%, specificity was 100%, positive predictive value (PPV) was 100%, and negative predictive value (NPV) was 98.6%. Sensitivity of FDG-PET was 16.7%, specificity was 95.8%, PPV was 50%, and NPV was 81.9%. At a median follow-up duration of 16.6 months, seven patients (10%) developed recurrent disease. PET predicted one recurrence (14.3%) in a node basin missed by SNB. CONCLUSION: FDG-PET is an insensitive indicator of occult regional lymph node metastases in patients with melanoma because of the minute tumor volumes in this population. FDG-PET does not have a primary role for staging regional nodes in patients with clinically localized melanoma.

9005 Background: Many studies have identified Sentinel Node (SN) tumor burden as a prognostic factor for additional non- SN (NSN) positivity and / or disease-free (DFS) and melanoma specific survival (MSS). It remains unclear if pts with minimal SN tumor burden can safely be managed without Completion Lymph Node Dissection (CLND). Pts with minimal SN tumor burden might be at risk for late recurrences (> 5 years). Methods: Slides of 595 SN positive patients were reviewed for this pan-European study collaboration in 5 major centers. Slides were reviewed for the microanatomic location and SN tumor burden according to the Rotterdam Criteria (< 0.1mm, 0.1 - 1.0mm and > 1.0 mm) for the maximum diameter of the largest metastasis. MSS, DFS and distant metastasis-free survival (DMFS) rates were calculated, as was NSN positivity. Results: In 595 SN positive pts, the mean and median Breslow thickness was 4.73 and 3.5 mm. Ulceration was present in 51% of melanomas. 67 pts had metastases < 0.1 mm (11%), 226 pts (38%) had 0.1 - 1.0 mm metastases and 302 pts had metastases > 1.0 mm (51%). Mean and median follow-up was 48 and 40 months for all patients (range 1 - 172). Patients with metastases < 0.1 mm had mean and median follow-up of 61 and 57 months, 46% (31pts) had follow up > 5 years and 25% (17 pts) had follow-up longer than 80 months (range 3 - 132). 5-year MSS rates were 94% for metastases < 0.1 mm, 70% for 0.1 - 1.0 mm and 57% for > 1.0 mm (p<0.001). 5-year DMFS rate was 91% for metastases < 0.1 mm. NSN positivity occurred in 5% of < 0.1mm, 17% of 0.1 - 1.0 and 29% of metastases > 1.0 mm (p<0.001). Conclusions: This large multicenter experience (n=595) has demonstrated that long-term follow-up of melanoma patients with minimal SN tumor burden (< 0.1 mm) indicates very low relapse rates and excellent MSS, seemingly identical to SN negative patients. With prolonged follow-up, an increase in the occurrence of relapses of any kind between 5 and 10 years follow up has not been identified, and excellent 10-year survival rates are expected. No significant financial relationships to disclose.

Abstract Introduction: Malignant paragangliomas have been well described in carriers of mutations of the succinate dehydrogenase B (SDHB) gene, but have rarely been associated with mutations in the succinate dehydrogenase D (SDHD) gene. Aim: The aim of the study was to report the different clinical expression patterns of malignant paragangliomas in five patients with SDHD (D92Y) mutations observed in approximately 200 SDHD (D92Y) mutation carriers followed in our institution. Results: Metastasis and/or local tumor invasion was documented 0 (n = 2), 1, 18, and 30 yr after the initial diagnosis of paraganglioma. Malignancy was proven by paraganglioma bone metastases (n = 2), intrathoracic paraganglioma with lymph node metastases, locally invasive head-and-neck paraganglioma with destruction of the petrosal bone, and locally invasive paraganglioma of the bladder with lymph node metastases. Four of the five patients developed catecholamine excess during follow-up due to intraadrenal paraganglioma (pheochromocytoma) (n = 1), extra adrenal paraganglioma (n = 2), and presumed subclinical disease (n = 1). Conclusion: SDHD mutations (D92Y) are associated with malignant paragangliomas and catecholamine excess with remarkable interindividual variations despite the same mutation. We estimate that the prevalence of malignancy in carriers of D92Y mutations is at least 2.5%.
