Abstract
The widespread use of (18)F-FDG PET-CT scanning in oncological patients has allowed to demonstrate the existence of metabolically active brown fat, also called brown adipose tissue (BAT), in adult humans, and specifying its anatomical distribution in vivo. As physiological determinants to BAT (18)F-FDG uptake has been identified gender, age, temperature, and body mass index. We have observed extensive activation of the BAT, including the mesenteric region, in a patient with a catecholamine-secreting para-vesical paranganglioma. The extensive BAT activation could be secondary to adrenergic stimulation due to excess of circulating norepinephrine concentration.

Abstract
Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare entity that accounts for less than 5% of the cases of Hodgkin lymphoma (HL) with morphological, immunophenotypical, genetic and clinical behavior traits different from the classic HL. In a minority of patients, the NLPHL course is complicated by a transformation to a non-Hodgkin diffuse large B-cell lymphoma (NHDLBCL) with prognostic and therapeutic implications. Early metabolic changes observed by (18)F-FDG PET in patients with HL and NHL, after 1-3 cycles of chemotherapy, predict the final response to treatment and progression-free survival. In the case we are presenting herein, whether NLPHL is transformed to NHDLBCL or the two types of lymphoma co-exist in the same patient, the (18)F-FDG PET/CT scan was crucial for the identification of tumor resistance to first line chemotherapy and to guide a second biopsy decision and therefore modify the chemotherapy regimen.

Abstract
We present the case of a patient with breast cancer who underwent selective sentinel lymph node biopsy. An intramammary sentinel lymph node was identified with SPECT/CT in the preoperative lymphoscintigraphy. We describe our diagnostic and therapeutic procedure regarding this finding and the literature review to evaluate the clinical significance of their identification and metastases, especially in regards to more appropriate axillary management. Further studies with more statistical significance are necessary to elucidate the most suitable attitude when an intramammary sentinel lymph node is identified with the lymphoscintigraphy.

Abstract
AIM The aim of this study was to evaluate the role of (99m)Tc-MIBI parathyroid scintigraphy and radioguided parathyroidectomy on the diagnosis and treatment of primary hyperparathyroidism (PHP) due to ectopic adenomas. METHODS We reviewed 105 consecutive patients who underwent radioguided parathyroidectomy due to adenomas between March 2004 and December 2008. Of this group we studied 20 patients (19%) with ectopic adenomas. All patients had biochemical evidence of PHP, a positive parathyroid scintigraphy, radioguided detection with histolopathological confirmation of adenoma and at least 1 year-follow up. The parathyroid scintigraphy consisted on dual-phase planar and tomographic images (SPECT or SPECT/CT). During the parathyroidectomy, intraoperative PTH determinations (0, 7, 15 and 30 min after the parathyroidectomy) were done. The follow up consisted on blood examinations of PTH, calcium, phosphorus and vitamin D and assessment of renal function. RESULTS Parathyroid scintigraphy detected all adenomas. Scintigraphic and surgical findings were coincident in 18 cases (90%). The final adenoma localization was paraesophagic in 9 patients, cervicothymic in 5, posterior cervicomediastinal in 4, anterior mediastinal in 1 and parathymic in 1. The parathyroidectomy consisted on 12 minimally invasive surgeries, 2 unilateral cervicotomies, 4 bilateral cervicotomies and 2 sternotomies. No case of persistent or recurrent PHP was observed during the follow up. CONCLUSIONS Parathyroid scintigraphy (SPECT/CT) and radioguided surgery are effective methods on the localization and treatment of PHP due to ectopic adenomas. In our study the radioguided parathyroidectomy was successful in all cases and there was no evidence of persistent or recurrent hyperparathyroidism on the follow up.

Abstract
The common sequence variants that have recently been associated with cancer risk are particular to a single cancer type or at most two. Following up on our genome-wide scan of basal cell carcinoma, we found that rs401681[C] on chromosome 5p15.33 satisfied our threshold for genome-wide significance (OR = 1.25, P = 3.7 x 10(-12)). We tested rs401681 for association with 16 additional cancer types in over 30,000 cancer cases and 45,000 controls and found association with lung cancer (OR = 1.15, P = 7.2 x 10(-8)) and urinary bladder, prostate and cervix cancer (ORs = 1.07-1.31, all P < 4 x 10(-4)). However, rs401681[C] seems to confer protection against cutaneous melanoma (OR = 0.88, P = 8.0 x 10(-4)). Notably, most of these cancer types have a strong environmental component to their risk. Investigation of the region led us to rs2736098[A], which showed stronger association with some cancer types. However, neither variant could fully account for the association of the other. rs2736098 corresponds to A305A in the telomerase reverse transcriptase (TERT) protein and rs401681 is in an intron of the CLPTM1L gene.

Abstract
OBJECTIVE Establish the usefulness of scintimammography (SM) in day-to-day clinical practice. MATERIAL AND METHODS We have evaluated 308 SM consecutively performed in our Department. The diagnosis was established by way of biopsy or clinical and mammography follow-up (minimum 18 months). In all cases we evaluated the kind of lesions (palpable or non-palpable) and their degree of suspicion of malignancy in the mammography (BIRADS). We determined the number of fine-needle aspiration cytology (FNAC) or biopsies performed in dependence of kind of lesions, mammography and SM results. RESULTS Final diagnosis was cancer in 18 % of the patients, and 71 % of the lesions were non palpable. Negative predictive value (NPV) of SM was 96 %. Pathological diagnosis was performed in 100 % of lesions with SM+ and 16 % of lesions with SM-. According to the kind of lesion, FNAC and/or biopsy was performed in 62 % of palpable lesions and in 20 % of non-palpable lesions; and according to the mammography in 21 % of lesions BIRADS I-II, 14 % in BIRADS III, 70 % in BIRADS IV and 100 % in BIRADS V. The number of FNAC and/or biopsies performed is significantly higher in all cases when SM is positive (p > 0,001), excepting in BIRADS V lesions. CONCLUSIONS In day-to-day clinical practice SM is generally performed in low prevalence of breast cancer population, in the evaluation of non-palpable lesions with a low suspicion of malignancy. SM has a high NPV, increase the diagnostic accuracy of the mammography and has repercussion on patient management, except in BIRADS V lesions.

Abstract
PURPOSE The purpose of this study was to retrospectively evaluate the hypothyroidism rate, persistence of hyperthyroidism and the complications after the administration of 131I in 3 cohorts defined according to the activity of 131I administered. METHODS We consecutively treated 659 patients diagnosed with Graves-Basedow disease (GBD) with 131I. The activity was determined on the basis of a protocol that we called "modulated fixed activity". A total of 45 patients (Group 1) who had previously undergone surgery were given small 131I activities of between 111-185 MBq (3-5 mCi), 247 patients (Group 2) with normal or almost normal-sized thyroids were given activities of between 222-333 MBq (6-9 mCi) and the 367 patients with diffuse goiters (Group 3) activities of between 370-555 MBq (10-15 mCi). RESULTS A total of 69.2 % of the patients presented hypothyroidism at the end of the follow-up period. By groups, the percentages of hypothyroidism at the end of the follow-up period were 69 %, 68.8 % and 69.6 % respectively. The average time for the patients to present hypothyroidism was 2.7 years with a maximum de 12.3 years and a minimum of 2 months. No severe precocious complications after the administration of 131I were noted. CONCLUSION The choice of the modulated fixed doses of 131I for treatment of the GBD is a simple method and permit treatment in only one day.

Abstract
10782 Background: Sentinel lymph node is a minimally invasive and accurate staging procedure for patients with invasive breast cancer. Histological SLN involvement with cancer cells requires regional lymph node dissection. Aim: To verify if subgroups of patients with sentinel lymph node involvement in which the risk of histological involvement of additional regional lymph nodes is minimal can be identified. Methods: Ninety six consecutive patients with invasive breast cancer and tumour size less than two centimeters by mammography, had lymphoscintigraphy with colloidal 99Tc and radioisotope-guided sentinel lymph node biopsy in the University Hospital of Zaragoza from 1999 to 2005.Pathological assessment included serial sections of the sentinel lymph node with inmunohistochemistry for cytokeratins in selected cases.39 patients had histological involvement and are presented in this analysis. Results: All 39 patients were females. Median tumour size was 20 mm (range 5–52) Median number of resected sentinel lymph node was 2 (range 1–5) Median number of involved sentinel lymph node was 1 (range 1–4) Regional lymph node dissection was performed in all patients (Axillary dissection in 31; internal mammary dissection in 1, both in 7). Median number of nodes was 13 (range 2–34) At least 1 additional involved lymph node was found in 19 patients (48%) We have correlated patient age, menopausal status, pathological tumour size, histological grade, estrogen receptors, progesterone receptors and Her2 with the risk of histological lymph node involvement in regional lymph node dissection. Conclusions: Tumour size was significantly associated to such risk: No significant financial relationships to disclose.

Abstract
10787 Background: Patients with breast cancer in which sentinel lymph node biopsy is histologically negative for tumor cells, have a low probability of having involvement of additional regional lymph nodes. Lymph node dissection may be avoided in these cases. Methods: Ninety-six consecutive patients with invasive breast cancer and tumour size less than 2 centimeters by mammography, had lymphoscintigraphy with colloidal 99Tc and radioisotope-guided sentinel lymph node biopsy in the University Hospital of Zaragoza from 1999 to 2005.Pathological assessment included serial sections of the sentinel lymph node with immunohistochemistry for cytokeratins in selected cases. Results: Sentinel lymph node biopsy was negative in 57 patients. There were 56 females and 1 male. Median age was 57 years (range 24–87). Median pathological tumor size was 15 mm (range 5–31). Location of the sentinel lymph node was axillary in 47patients, internal mammary in 0 patients, and both in 10 patients. Median number of resected lymph nodes was 2 (range 1–4). With median follow-up of 33 months, no local or systemic relapses have occurred. Conclusions: Avoidance of regional lymph node dissection is safe in patients with breast cancer and histologically negative sentinel lymph node biopsy. No significant financial relationships to disclose.

Abstract
AIMS To evaluate the response to Sm153-EDTMP treatment in patients with metastatic bone pain and the existence of differences in the response according to the scintigraphic pattern (99mTc-MDP) and the primary tumor. MATERIAL AND METHODS We have evaluated the response to Sm153-EDTMP treatment in 32 patients (17 male and 15 female) who received 38 doses (1 mCi/kg). The primary tumor was prostate cancer in 15 patients, breast in 13, lung in 2, intestinal carcinoid in one and unknown in one. Two types of response were considered: a) effective and b) non-effective. Patients were classified into 3 groups according to the metastatic pattern: 1) Superscan (SS), 2) Generalized metastases (GM) and 3) Regional metastases (RM). RESULTS There was effective response in 24 doses (63.15%) and non-effective in 14 (36.84%). The mean duration of the response was 12.08 weeks. Patients with GM pattern showed 16 effective responses (76.19%) and 5 non-effective (23.8%). In SS pattern there were 6 effective responses (60%) and 4 non-effective (40%) and 2 effective (28.57%) and 5 non-effective (71.53%) in RM pattern. These differences did not reach statistical significance (p > 0.05). We did not find differences in the response between prostate cancer (12 effective and 6 non-effective) and breast cancer (10 effective and 6 non-effective) (p = 0.79968). CONCLUSIONS Sm153-EDTMP treatment is efficacious in patients with metastatic bone pain with effective response in 63.15% of the treatments. The response percentage was lower in patients with RM pattern but the differences did not reach statistical significance. There were no differences in the response between prostate and breast cancer patients.

Abstract
OBJECTIVE The aim of this study has been to retrospectively assess the usefulness of 111In-DTPAOC scintigraphy in the detection of bone metastases (BM) in patients diagnosed of carcinoid tumour (CaT). MATERIALS AND METHODS Between June 1995 and April 2003 78 111In-DTPAOC studies were consecutively performed in 58 patients, 31 females and 27 males, 28 to 73 years old, with a histological diagnosis of CaT. Moreover, whole body bone scans (BS) using 99mTc-MDP were performed in 13 of these patients. The patients were classified into three groups: Group A: Initial CaT staging (n = 23); Group B: CaT staging after surgery (n = 14); and Group C: Post-treatment CaT re-staging (n = 29). In this last group, 6 patients of group A and 2 patients of group B were included. In only 2 patients the diagnoses of bone metastases were established before the 111In-DTPAOC scan. RESULTS Twenty six (44.8 %9 of the 58 patients with CaT had metastatic disease: 15 patients with hepatic metastases, associated with BM in 4 of them, 10 patients with hepatic and extra-hepatic metastases, abdominal and/or thoracic, associated with BM in 4 and in one patient, the BMs were the only metastases detected. The global incidence of BM in patients diagnosed with CaT was 15.5 % (9/58), whereas the incidence of BM in patients with metastasic disease was 34.6 % (9/26). Significant differences (p = 0.0035) were found on the incidence of BM in patients with or without hepatic metastases. In 4 patients, BMs were detected during the initial staging (group A), whereas in 5 patients, BMs were detected during the post-treatment re-staging (group C). During diagnosis, 4 of the 9 patients with BM had bone pain. BM were multiples in 8 patients, affecting axial skeleton in 4 and axial and appendicular skeleton in 4. One patient had a diffuse infiltration of bone marrow. BS was positive in 8 of the 9 patients with BM. In these 8 patients with abnormal BS, 111In-DTPAOC scintigraphy provides similar information to the BS in one patient, shows a greater number of bone lesions in 3, whereas BS was superior in 5 patients. Four of the patients with BM died between 6 and 47 months after diagnosis (mean: 29.7 months). CONCLUSIONS BMs are preferably located on axial skeleton, can be asymptomatic and are associated with hepatic metastases. Although the 111In-DTPAOC scintigraphy is able to detect some BM earlier than BS, the information provided by both studies is complementary. In patients with CaT, any invasive therapy on the hepatic metastases make it necessary to exclude extrahepatic metastases, including bone ones, and the somatostatin receptor scintigraphy is the diagnostic method of choice.

Abstract
PURPOSE We report a case of a rectal carcinoid tumor that was treated using endoscopic resection. This case highlights the usefulness of using somatostatin receptor scintigraphy in the postresection endoscopy of the tumor and the intraoperative use of a gamma probe detector for the surgical resection of metastatic adenopathy that had not been detected using computed tomography (CT) scanning. METHODS The patient was studied using CT scanning, somatostatin receptor scintigraphy (SRS), and rectal endoscopic ultrasonography (EUS). A gamma probe detector was scheduled for use during the subsequent surgical intervention. RESULTS The SRS demonstrated a pelvic metastatic lymphatic node that had not been detected on CT scanning. Additional EUS did not show regional metastatic lymph nodes. Histopathology following removal of retroperitoneal and presacral lymphatic nodes confirmed the diagnosis of metastatic carcinoid tumor. At follow up at 6 months, SRS and rectoscopy were normal. CONCLUSION Somatostatin receptor scintigraphy is very useful in identifying the presence of lymph node metastases, even with a small rectal carcinoid tumor. This is of considerable importance when scheduling surgery and the CT and EUS are normal. The use of an intraoperative gamma-probe detector assists in the surgical excision of the metastatic lymphatic nodes, especially because they had been detected only using SRS, and when their exact location is uncertain.

Abstract
The aim of this work has been to evaluate the clinical usefulness of 99mTc-MIBI scintimammography, used as a complement to mammography, in the study of patients with suspected breast cancer. We performed prone breast scintigraphy in 253 patients (268 lesions) with suspected breast cancer. The size and degree of the suspected breast cancer was evaluated by mammography. Diagnosis was established by biopsy. Malignancy was diagnosed in 155 lesions and benign diseases in 113. The results of the scintimammography were a sensitivity of 91%, a specificity of 71%, PPV=81% and NPV=85%. In lesions smaller than 1 cm, sensitivity and specificity were 57% and 100%; in lesions with a diameter of between 1 and 2 cm, these figures were 90% and 72% respectively, and in lesions of more than 2 cm the sensitivity was 99% and the specificity 50%. On mammography, 155 lesions were considered as having a high suspicion of malignancy, whilst 72 were indeterminate and 41 had a low probability. In lesions with a low or indeterminate suspicion of malignancy on mammography, the sensitivity and NPV of the scintimammography were 97% and 98%. Scintimammography is a useful technique in the study of lesions where breast cancer is suspected. Scintimammography results are closely related to tumour size and the degree of mammographic suspicion. Scintimammography can be useful where mammography identifies lesions with a low or indeterminate suspicion of malignancy.

Abstract
A 68 year old Ecuadorian man was investigated for polyuria, polydipsia and weight loss of 3 kg during the previous two months. Insulin dependent diabetes mellitus was diagnosed 10 year before admission and treated with appropriate diet and insulin (35 U/d). 18 months before was diagnosed in El Ecuador of "multiple liver nodes non-suggestive of malignancy". Physical examination showed a large multinodular petrous hepatomegaly. There was no evidence of skin lesions. Results of laboratory studies included a basal plasma glucose level that ranged between 275-367 mg/dl (N=60-100), glycosylated haemoglobin of 8.9% (N<5) and a serum albumin of 2.8 gr./dl (N=3.4-4.8). At admission non-other laboratory alterations were detected. Computed tomography showed a mass on the head of the pancreas with loco-regional lymph nodes and liver metastases. Tumor markers were normal. Fine-needle aspiration cytology of the liver masses revealed the presence of liver metastases of a non-differentiated malignant tumor. A 111In-DTPAOC scintigraphy revealed the presence of somatostatin receptors in the liver metastases, also detecting the presence of multiple bone metastases in the axial and appendicular skeleton. Plasma glucagon level was 678 pg/ml (N<250). A diagnosis of metastatic glucagonoma was established and therapy with streptozocin, 5-FU, insulin and synthetic somatostatin analogs was initiated. Three months after the therapy initiation the patient was symptom free. Some weeks after the patient suffered from left hip pain, and a control 111In-DTPA scintigraphy showed progression of his bone metastases. In conclusion, glucagonoma must be suspected in all diabetic patients with metastatic liver, even in absence of necrotic migratory erythema. In these circumstances, plasmatic glucagon level and somatostatin receptors scintigraphy will be a useful tool for establishing the final diagnosis.

Abstract
UNLABELLED Somatostatin receptor scintigraphy has become an essential tool in the treatment planning of patients with carcinoid tumor (CaT) and pancreatic neuroendocrine tumors (PNET). However, the contribution of SPECT images in the diagnosis and staging of these tumors has not been well established. OBJECTIVE 1) To find out if SPECT improves the sensitivity of planar imaging and adds any value to tumor diagnosis, and 2) To determine under which circumstances SPECT images must be obtained. MATERIAL AND METHODS We have evaluated 49 patients, 26 females and 23 males, using both planar and SPECT 111In-DTPAOC images. The patients were classified into three groups according to their clinical indication: Group A: Indolent symptoms of CaT or PNET (n = 9); Group B: Known or functioning CaT or PNET tumors (n = 22); Group C: Post-surgical follow-up (n = 18). The total number of SPECT studies were 51 (37 abdomen, 13 thorax and 1 brain). In all cases SPECT was performed 24 hours after 111In-DTPAOC injection. Scintigraphic images were compared with surgical findings in 17 patients and with a synthesis of biochemical, clinical and CT findings in the other patients. RESULTS 16 primary lesions were detected with planar images whereas SPECT detected 18. The two tumors detected only by SPECT were a bronchial CaT and an insulinoma located in the pancreatic tail. Planar and SPECT image sensitivities were 66.6% and 75% respectively. Twenty one patients developed metastatic disease. Sensitivities of planar and SPECT images for metastases were 76.1% and 90.4% respectively. Furthermore, SPECT helps planar images in the evaluation of six patients with uncertain images (lesions with low receptor density or with an uncertain scintigraphic localization). Therefore, in 15.6% of patients with primary or metastatic tumors, planar images were normal whereas SPECT was abnormal and SPECT provided an added value in 21.8% of the studies with abnormal planar images. CONCLUSIONS We recommend the use of SPECT images in: 1) Patients with specific functional clinical syndrome or with a known CaT or PNET and normal planar images. 2) When planar images are abnormal only in primary tumor. 3) In order to confirm the absence of other metastases in patients with known liver metastases. 4) In order to enhance the detection of lesions with low receptor density and uncertain planar images and 5) In order to determine exactly the anatomic location of some lesions
