    Full Text Available Objective: carcinoid tumors (CTs represent the commonest neuroendocrine tumors. Those in the gastrointestinal tract are diagnosed in surgical specimens, clinically, and using imaging techniques (endoscopy, echoendoscopy, CT, Octreoscan, etc.. The goal of this retrospective study was to review a personal series of gastrointestinal carcinoid tumors, and to compare it to those in the literature. Patients and methods: the medical records of 40 Caucasian patients with over 50 gastrointestinal carcinoid tumors (including multiple cases who were seen for a period of 16 years (1994-2009 were reviewed. Results: mean age at presentation was 52 years, 50% were females, and mean tumor size was 9.9 mm. Most were gastroduodenal (42.5% or rectal (30%, and were treated endoscopically. Metastases and carcinoid syndrome (CS were seen in 5% of patients. Survival at study endpoint was 85%. Conclusions: age and gender were consistent with the literature. There was an increase in gastroduodenal (multifocal and rectal carcinoids, likely because the series was essentially endoscopical in nature (bias. There was a lower rate of CS and higher survival, likely due to earlier diagnosis and treatment.Objetivo: los tumores carcinoides (TC son los tumores neuroendocrinos más frecuentes.

  5. Scintiscans and carcinoid tumors

    International Nuclear Information System (INIS)

    The presence of somatostatin receptors on carcinoid tumors mediate imaging of tumor extent and inhibition of tumor's marker secretion and growth. This prospective study aimed to evaluate radiolabelled somatostatin analogues scans in the therapeutical work-up of carcinoids. Twenty-one patients with carcinoids underwent 26 scans with iodine octreotide or indium pentetreotide. The results for tumor and metastase imaging were analysed and compared to those of a short inhibition test of marker secretion and to those of MIBG scan. The sensitivity for imaging the overall 43 tumor sites was 72%. We had no false positive. Unknown tumors were discovered in three patients. The results were slightly better with indium pentetreotide and in metastase imaging. A positive scan did not always preclude responsiveness to the functional effect of octreotide. Results of somatostatin analogue scans were better than those with MBG. The two techniques showed complementary in one patient. Treatment decision making in patients with carcinoid tumors should benefit from functional inhibition test by octreotide as well as from indium pentreotide and MIBG scans.

    Full Text Available Carcinoid tumors are rare tumors in practice of doctors of various specialties. These tumors are histological findings in the most cases because they are masked by clinical and morphological features of neoplastic and non-neoplastic diseases. In some cases, carcinoid tumors generally remain undetected due to lack of awareness among physicians about clinical and morphological characteristics of such disease. Believe it is important to recall the features of this tumor. The article presents the literature data and own observations from practice of carcinoid tumor of rare localization: bronchus, colon, mammary gland. In all three of our observations, where cancer was clinically suspected, the diagnosis of carcinoid tumor was made only after histology. Only complications have led to the surgical intervention, and, unfortunately, the diagnosis of carcinoid was made after death. In the latter case carcinoid most likely played an important role in thanatogenesis. Unification of efforts of doctors in various fields will make progress in the diagnosis and treatment of carcinoid tumors, extending the lives of patients suffering from this disorder.

    Full Text Available Carcinoid tumors are rare. They may appear in the entire gastrointestinal and respiratory tracts, with single or multiple occurrences. Prognosis is dependent on the size and location. Symptoms may appear in carcinoid syndrome, related to active substances, especially serotonin. One important aspect associated with these tumors and usually ignored is fibrogenesis. This is a case report of a patient with carcinoid tumor of the terminal ileum, treated by laparoscopy, associated with fat and fibrosis infiltration.Tumores carcinoides são pouco frequentes, podem surgir em todo o trato gastrointestinal e respiratório, podem ser únicos ou múltiplos. O prognóstico depende do tamanho e da localização do tumor. Podem ocorrer sintomas relacionados à síndrome carcinoide, decorrente da produção de substâncias ativas, em especial serotonina. Um aspecto comumente ignorado associado a estes tumores é a estimulação da fibrogênese.

    To compare intraluminal ultrasonographic (ILUS) findings with histological findings of rectal carcinoid tumors, 35 patients with rectal carcinoid tumors were reviewed. The results were as follows: 1) The rectal wall was visualized as a seven- or nine-layer structure by means of ILUS in 81% of the patients. 2) The possibility that the thin hyperechoic third layer above the tumor on ILUS corresponds to the muscularis mucosae and fibrointerstitium above the tumor histologically. 3) In cases with relatively high internal echoes, the amount of fibrointerstitium exceeded that of tumor cells histologically. 4) In cases with nonuniform internal echo patterns, tumor cells were separated by thick fibrointerstitium forming nodular nests.

    Although carcinoid tumors are labeled as neuroendocrine tumors they can also originate in tissue lacking neuroendocrine cells, such as that in the middle ear. Symptoms of a carcinoid tumor in the middle ear are common ear symptoms such as fullness, pain and hearing loss. Carcinoid tumors have also been considered to be slow-growing. Both these aspects can easily lead to a relatively late diagnosis of carcinoid tumor of the middle ear. The diagnosis is made histologically, and the tumor is primarily treated surgically. In the follow-up of patients, octreotide scanning has proved to be a sensitive method in cases of both recurrence and metastasis. Our patient was a 34-year-old, otherwise healthy female with left-sided acute otitis media and facial palsy in her left ear. She had also suffered from the same symptoms 4 years earlier. She was treated with an operation, and the histologic diagnosis was a carcinoid tumor. In the follow-up of the patient we used octreotide scanning.

    Directory of Open Access Journals (Sweden)

    George C. Nikou

    2012-01-01

    Full Text Available Gastric carcinoid tumors (GCs are rare lesions representing less than 10% of carcinoid tumors and less than 1% of all stomach neoplasms. There are three distinct types of gastric carcinoids; type I includes the vast majority (70–85% of these neoplasms that are closely linked to chronic atrophic gastritis. Type II which accounts for 5–10 %, is associated with Zollinger-Ellison syndrome and often occurs in the context of multiple endocrine neoplasia type 1. Type III, finally, represents 15–25% of gastric carcinoids and is characterized by a far more aggressive course. The optimal clinical approach to GCs remains to be elucidated, depending upon type, size, and number of carcinoids. While there is universal agreement about the surgical treatment of type III GCs, current options for type I and II include simple surveillance, endoscopic polypectomy, surgical excision associated with or without surgical antrectomy, or total gastrectomy. Moreover, the introduction of somatostatin analogues could represent another therapeutic option.

    Full Text Available Carcinoid tumors conform less than 1% of all testicular tumors and most of them are neuroendocrine tumors which are primarily seen in testes. They are in the form of testicular metastasis from other organs. Carcinoid tumors may occur from differentiation of malignant teratomas. The main distinguishing feature of carcinoid tumors from other germ tumors is that they can be seen in all age groups. Histopathologically they have been described in two forms: well-differentiated and moderately differentiated. We aimed to discuss about a primary testicular carcinoid tumor in a 29 year old male patient.

CT scan showed a multilocular cyst (5 cm in diameter) with a solid tumor in the left kidney which was enhanced with contrast. There was no evidence of extrarenal invasion or distant metastasis. We performed retroperitoneal laparoscopic radical nephrectomy. Pathological examinations revealed a cellular arrangement specific to carcinoid tumor and positive for CD56 (NCAM) and neuron-specific enolase. The cell proliferation rate was estimated to be under 2% with Ki67 staining. The pathological diagnosis was renal neuroendocrine tumor (carcinoid). At the 9-month follow up, he had no evidence of local recurrence or metastasis.

    The patient is an 82 year-old female with a history of osteoarthritis, hypothyroidism and anemia for 14 years (receiving blood transfusions). She was admited to our hospital with a nine months history of malaise, anorexia, fatigue and weakness, associated with intermitten episodes of abdominal pain. She was diagnosed anemia and occult blood positive stools. Physical examination revealed a patient in generally fair condition, obese, with mild edema of lower limbs, no changes in the evaluation of chest, cardiovascular, abdomen, etc. Laboratory data was unremarkable, except for iron deficiency anemia. The upper endoscopy showed duodenal ulcer scar, fundic polyposis and chronic gastritis. Colonoscopy revealed some diverticula, a small sessile polyp and internal hemorrhoids. The diagnosis of obscure gastrointestinal bleeding was made. The CT scan of the abdomen showed gallstones and fatty liver; a radiograph of intestinal transit detected a lesion apparently protruded intestinal loop for distal jejunum; enteroscopy was performed (with one team ball) anterograde and retrograde achieving assess distal jejunum and distal ileum without observing any injuries. The study of capsule endoscopy showed a polypoid tumor intestinal with evidence of having bleeding. Surgery detected the tumor in proximal ileum. The surgical specimen findings showed three tumors 0.7 mm, 10 mm and 15 mm on the proximal ileum. The microscopic examination revealed that these lesions were neuroendocrine tumors (carcinoid). The Ileal carcinoid tumor may rarely presented with obscure gastrointestinal bleeding. PMID:21544161

  2. Endoscopic Management of a Primary Duodenal Carcinoid Tumor

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available Carcinoids are rare, slow-growing tumors originating from a variety of different neuroendocrine cell types. They are identified histologically by their affinity for silver salts and by positive reactions to neuroendocrine markers such as neuron-specific enolase, synaptophysin and chromogranin. They can present with various clinical symptoms and are difficult to diagnose. We present the case of a 43-year-old woman who was referred for evaluation of anemia. Upper endoscopy showed a duodenal bulb mass around 1 cm in size. Histopathological and immunohistochemistry staining were consistent with the diagnosis of a carcinoid tumor. Further imaging and endoscopic studies showed no other synchronous carcinoid lesions. Endoscopic ultrasound (EUS revealed a 1 cm lesion confined to the mucosa and no local lymphadenopathy. Successful endoscopic mucosal resection of the mass was performed. Follow-up surveillance 6 months later with EUS and Octreoscan revealed no new lesions suggestive of recurrence. No consensus guidelines exist for the endoscopic management of duodenal carcinoid tumors. However, endoscopic resection is safe and preferred for tumors measuring 1 cm or less with no evidence of invasion of the muscularis layer.

  3. Bronchial carcinoid tumors: clinical and radiological findings in 21 patients

    International Nuclear Information System (INIS)

    Bronchial carcinoid tumors are neoplasms that range from typical carcinoid s to the more aggressive atypical ones with similar imaging features. Considering the low prevalence of the tumor, we reviewed 21 patients. Patients and methods: in this retrospective observational study, we reviewed the clinical, pathological and imaging findings in 21 patients diagnosed with bronchial carcinoid tumors who were admitted to National Research Institute of Tuberculosis and Lung Disease in a 6 years period. Plain radiography and CT scan of patients were reviewed. Results: 52.4% of the patients were male and 47.6 % female. The mean age of patients was 39.1 years. The most frequent clinical symptoms were cough (n=15; 71.4%), hemoptysis (n.13; 61.9%). dyspnea (n=12; 57.1%). and pleuritic chest pain (n.7; 19%). Most of the lesions (68%) were in the right lung, 24% in the left lung. 8% in the trachea, and 19% were bilateral. Right upper lobe and right intermediate bronchus (24% and 32% respectively) were the most frequent sites of tumor. In radiologic examination, two cases (9.5%) had normal CXRs. Pulmonary collapse (52.4%) and mass (23.8%) were the most frequent findings. Reviewing CT scans showed endobronchial lesion in three (15%) and mass in 11 (55%) patients. The mass was well defined in 8 cases (72%) and ill-defined in 3 (28%). Other findings were: mediastinal invasion (45%), atelectasis (55%). post obstructive pneumonitis (2 0%) and eccentric calcification (15%). Pathological examination revealed typical (n=18: 86% ) and atypical (n.3: 14%) carcinoid tumors. Conclusion: although rare, bronchial carcinoid tumors should be considered a differential diagnosis in adult patients with cough, hemoptysis, dyspnea, and pleuritic chest pain. Chest xray and CT scan can help with diagnosis. Major imaging findings are central, round or ovoid well-defined mass, and obstruction signs like at electasis. Diagnosis and classification should be confirmed by pathological examination on sample

    Background Ki-67 is nuclear protein with essential role in the control and timing of cell proliferation, largely studied in neuroendocrine tumors, but yet without clear clinical implications. A difference of percentage of Ki-67 labeling index (LI) was observed in different neuroendocrine tumors. This study intended to determine difference of Ki-67 LI between typical (TC) and atypical lung carcinoid (AC) using imunohistochemical methods, and to correlate clinical parameters with percentage of Ki-67 LI in TC and AC. Methods and participants A total of 49 specimens of TC and AC between year 2007 and 2009 were retrieved from our archive. Minimum follow-up period was 5 years. The clinical parameters included age, gender, tumor size, node and metastasis stage, recurrence of disease, therapy and overall survival (OS). Ki-67 was evaluated in the areas of highest positivity, and expressed as percentage of 400 tumor cells. Results Median value Ki-67 LI for atypical carcinoid was 17.1 (min 1.5, max 61.5). Median value Ki-67 LI for typical carcinoid was 3.8 (min 0.3, max 16). Although there is statistical difference in an average tumor size between AC and TC (P=0.02), there was no correlation between tumor size and Ki-67 expression. There was statistical difference between AC and TC concerning recurrence/metastatic disease (P=0.01) and OS (P=0.004), but none is in any relation with Ki-67 LI. The 5-year OS for typical carcinoid is 97.4% (95% CI: 97.3-97.5). The 5-year OS for atypical carcinoid is 60% (95% CI: 30-90). Conclusions Our study showed that Ki-67 LI was useful in dividing TC and AC, which is in concordance with published data. We also demonstrated that lower Ki-67 LI correlated with survival of the patients, regardless of carcinoid type. This study did not show any significant difference between AC and TC and Ki-67 LI in regards with age, gender, tumor size, recurrence/metastatic disease, therapy and overall survival, probably because small number of participants.

    Biopsy of rectal carcinoid tumor is commonly taken before endoscopic resection. However the preceding biopsy can inhibit complete resection by causing blurred tumor border and fibrosis of the tissue. The objective of the study was to investigate the effect of preceding biopsy on complete endoscopic resection in rectal carcinoid tumor. It was also determined if rectal carcinoid tumors can be macroscopically distinguished by endoscopy. We reviewed retrospectively the records of patients with re...

    Neuromyelitis optica (NMO), or Devic's syndrome, is an autoimmune central nervous system demyelinating disorder primarily affecting the spinal cord and the optic nerves. It is characterized by the presence of NMO antibodies, alongside clinical and radiological findings. NMO and NMO-spectrum disorders (NMO-SD) have been reported in autoimmune disorders, and are infrequently described as a paraneoplastic syndrome with cancers of lung, breast, and carcinoid tumors of the thyroid. We report a patient who presented with severe vomiting, blurring of vision, vertigo, diplopia, left hemiparesis and hemisensory loss and ataxia. She was found to have a longitudinally-extensive demyelinating lesion extending from the medulla to the upper cervical spinal cord on MRI. Her gastric endoscopy revealed carcinoid tumor of the stomach, and classic paraneoplastic antibodies in the serum were negative. She had extremely high serum gastrin level and high titer of NMO IgG autoantibody. The patient made an excellent recovery with tumor resection and immunotherapy, with both clinical and radiological improvement. On rare instances, NMO or NMO-SD may present as a paraneoplastic neurological syndrome associated with carcinoid tumor of the stomach.

    Gastrointestinal stromal tumor is the most common mesenchymal tumor in the gastrointestinal tract. It may coexist with other type of cancers, and if so, the tumors usually involve the stomach. The most common associated cancers are gastrointestinal carcinomas. We report a 65-year-old woman with a history of gastric gastrointestinal stromal tumor who had undergone subtotal segmental gastrectomy. New polypoid lesions were detected on a follow-up gastroscopy one year later. The lesions were biopsied and found to be carcinoid tumors. There was serum hypergastrinemia, and type 1 gastric carcinoid tumor was diagnosed. A total gastrectomy was performed. Pathologic examination revealed both carcinoid tumors and a recurrent gastrointestinal stromal tumor.

    Carcinoid tumors have been reported in a wide range of organs but most frequently involve the gastrointestinal tract; however, duodenal carcinoid tumors are rare. We report a 50-year-old male patient complaining of multiple melenas for 3 wk. The panendoscopy and endoscopic retrograde cholangiopancreaticography revealed swelling accessory papilla with an ulcer. The biopsy taken showed a carcinoid tumor. The lesion was removed by wide resection. Patient was found to have an abnormal blood cell count during the follow-up period with elevated levels of hemoglobin and hematocrit of 21.2 g/dL and 63.5%,respectively, thrombocytosis of 501 000/μL, and leukocytosis of 20 410/μL. He was diagnosed as a polycythemia vera by a hematologist after further evaluation. He received periodic phlebotomy and hydroxyurea treatment. The response was good and his hematocrit was stabilized by periodic phlebotomy in the range of 44-49% during the last 2 years. The possible origin of UGI bleeding by a duodenal carcinoid tumor, although rare, should be considered. There has been one case report of a duodenal carcinoid tumor that involved accessory papilla of the pancreas divisum and one case report of metastatic carcinoid tumor associated with polycythemia vera. It is different in our patient as compared with the latter report, which mentioned a polycythemia vera patient who was found to have a metastatic carcinoid in the 17 years follow-up period. Chemotherapy had been given before the carcinoid tumor was revealed. Our patient had no previous chemotherapy for polycythemia vera before he was found to have duodenal carcinoid tumor; this excludes the possibility of chemotherapy induced carcinoid tumor, although it had been suspected in the previous report. In our patient, the existence of both diseases may be by predisposition of each other since both diseases have an increased incidence of other neoplasm, or they may be coexistent incidentally.

    Purpose: To describe the imaging presentation of carcinoid tumors of the small-bowel at 64-section CT-enteroclysis and determine the sensitivity of this technique for tumor detection. Patients and methods: The 64-section CT-enteroclysis examinations of 22 patients with histopathologically proven small-bowel carcinoid tumors and those of 6 patients with suspected recurrence after small-bowel resection for carcinoid tumor were reviewed. Images were analyzed with respect to imaging presentation. Sensitivity, specificity, and accuracy, of 64-section CT-enteroclysis for the diagnosis of carcinoid tumor of the small-bowel were estimated with 95% confidence intervals (CIs). Results: Twenty-five carcinoid tumors were confirmed in 22 patients (prevalence, 22/28; 79%). Overall sensitivity for carcinoid tumor detection was 76% (19/25; 95%CI: 55–91%) on a per-lesion basis. On a per-patient basis, 64-section CT-enteroclysis had a sensitivity of 86% (19/22; 95%CI: 65–97%), a specificity of 100% (6/6; 95%CI: 54–100%) and an accuracy of 89% (25/28; 95%CI: 72–98%) for the diagnosis of carcinoid tumor. Focal small-bowel wall thickening, mesenteric stranding, and mesenteric mass were found in 20/22 (91%), 18/22 (82%) and 15/22 (68%) patients with pathologically confirmed tumors. Conclusion: 64-Section CT-enteroclysis shows highly suggestive features for the diagnosis of carcinoid tumor of the small-bowel and achieves high degrees of sensitivity for tumor detection.

    Type T gastric carcinoid tumors result from hypergastrinemia in 1%-7% of patients with pernicious anemia. We diagnosed pernicious anemia in a 48-year-old female patient with complaint of fatigue for three months.She had no gastrointestinal symptoms. Endoscopic examination ot the upper gastrointestinal tract revealed atrophic gastritis and a polypoid lesion in the corpus of 3-4 mm in size. Endoscopic polypectomy was performed.Histopathological examination of the specimen revealed positive chromogranin A and synaptophysin stainings compatible with the diagnosis of a carcinoid tumor. Serum gastrin level was increased, urinary 5-hydroxyindoleacetic acid was within the normal range.There was no other symptom, sign, or laboratory finding of a carcinoid syndrome in the patient. No metastasis was found with indium-111 octreotide scan, computed tomographies of abdomen and thorax. Type Ⅰ gastric carcinoid tumors are only rarely solitary and patients with tumors < 1 cm in size may benefit from endoscopic polypectomy.

    I-131 MIBG, a specific radiopharmaceutical agent for scintigraphic imaging and treatment of pheochromocytoma and neuroblastoma may be useful for detection of apudomas. Scintigraphy with I-123 radiolabeled MIBG was performed in a patient with metastatic carcinoid tumor from the rectum. I-123 MIBG scintigraphic findings showed multiple areas of abnormal tumor uptake of hepatic and bone metastases from the rectal carcinoid. Bone scintigraphy demonstrated multiple metastatic lesions. Computed tomography revealed multiple solid tumors of the liver. This report describes accumulation of I-123 MIBG in the liver and bone metastases from the rectal carcinoid. Radioiodine MIBG scintigraphy may be useful for detecting metastatic lesions, for evaluating postoperative recurrence, and also for the treatment of the carcinoid tumor. PMID:7788995

    In recent years, transoral robotic surgery has been introduced as an efficient and a reliable method for excision of selected oral cavity, tongue base, and supraglottic tumors in otolaryngology. In this case report, a 39-year-old woman with a history of hoarseness and dysphagia for approximately 6 months is presented. The patient was diagnosed with atypical carcinoid tumor on the laryngeal aspect of the epiglottis, and excision of the tumor was performed through transoral robotic surgery using the robotic da Vinci surgical system, a 0-degree three-dimensional endoscope, 5-mm microinstruments compatible with the da Vinci robot, and a Feyh-Kastenbauer/Weinstein-O'Malley retractor. The mass was removed completely, and no complications occurred. The patient recovered without a need for tracheotomy. Findings of the 1-year clinical follow-up revealed no locoregional recurrence or distant metastasis. This case shows, once again, that transoral robotic surgery could be used safely and effectively regardless of pathologic diagnosis in the supraglottic region tumors. PMID:24220389

    Full Text Available Context: Carcinoid tumors represent a group of well-differentiated tumors originating from the diffuse endocrine system outside the pancreas and thyroid. The overall prevalence of carcinoid tumors in the United States is estimated to be one to two cases per 100,000 persons. Various sites of origin of this neoplasm are appendix - 30-45%, small bowel - 25-35% (duodenum 2%, jejunum 7%, ileum 91%, multiple sites 15-35%, rectum 10-15%, caecum - 5%, and stomach - 0.5%. Liver metastases from jejunal and ileal carcinoids are generally hypervascular. Case report: Here we report a case of primary jejunal carcinoid tumor in a 66-year-old woman metastasizing to liver with ultrasonography, computed tomography, and diffusion-weighted magnetic resonance imaging (DWI findings. Conclusion: Primary jejunal carcinoid tumor is a rare entity. DWI can help in the differential diagnosis of hepatic hypervascular metastatic mass lesions from benign ones, as well as in the diagnosis of carcinoid tumor.

    Few clinical studies have demonstrated an anti-proliferative activity of somatostatin (SST) analogs in carcinoids. We report the case of a woman with liver metastases of neuroendocrine tumor and no evidence of the primary tumor. The liver metastases were characterized by high proliferation indes, immunoreactiviy for somatostatin receptor (SSTR) -1,2,3 and 5and positive octreoscan. Urinary 5-hydrozyindolacetic acid, serum serotonin and chromogranin A were elevated. Slow release lanretoide (SR-LAN) therapy for 3 mo controlled clinical and biochemical signs of carcinoid tumor and caused a clear-cut reduction in the diameter of two liver metastases and disappearance of another lesion, with further reduction after 6 and 18 mo. We demonstrated a Clear-cut long-lasting antioccult carcinoid with high proliferation index and immunoreactivity for SSTR-1,2,3, and 5. Immunohistochemistry for SSTRs could be a suitable method for the selection of patients with metasatic carcinoid that may benefit from SST analog therapy.

    Neuroendocrine tumors of the appendix(NET-A), formerly called appendiceal carcinoids, are rare tumors of the gastrointestinal tract.Appendiceal tumors have also been associated with infertility. However, in many of these cases, significant abdominal pathology, specifically pseudomyxoma peritonei, was identified during definitive surgical intervention.A34-year-old nulligravid woman undergoing infertility evaluation presented to an academic tertiary care fertility center. An abnormal mass was identified on hysterosalpingogram andCT confirmed appendiceal mass. Surgical removal of the mass was performed and histopathology was consistent with anNET-A with negative margins extending to the serosa.Two months after surgical intervention, the patient spontaneously conceived pregnancy and subsequently delivered a normal infant.This case exemplifies the importance of careful inspection of radiologic films by the gynecologic physician. Of added interest, this case describes an asymptomaticNET-A associated with primary infertility. To our knowledge, this is the first report of an incidentally indentifiedNET-A that resulted in primary infertility.

    AIM: Rectal carcinoid tumors smaller than 10 mm can be resected with local excision using endoscopy. In order to remove rectal carcinoid tumors completely, we evaluated endoscopic mucosal resection with a ligation device in this pilot control randomized study.METHODS: Fifteen patients were diagnosed with rectal carcinoid tumor (less than 10 mm) in our hospital from 1993 to 2002. There were 9 males and 6 females,with a mean age 61.5 years (range, 34-77 years).The patientshad no complaints of carcinoid syndrome symptoms. Fifteen patients were randomly divided into 2 groups: 7 carcinoid tumors were treated by conventional endoscopic resection, and 8 carcinoid tumors were treated by endoscopic resection using a ligation device.RESULTS: All rectal carcinoid tumors were located at the middle to distal rectum. The size of the tumors varied from 3 mm to 10 mm and background characteristics of the patients were not different in the two groups.The rate of complete removal of carcinoid tumors using a ligation device (100%, 8/8) was significantly higher than that of conventional endoscopic resection (57.1%,4/7). The three patients had tumor involvement of deep margin, for which additional treatment was performed.No complications occurred during or after endoscopic resection using a ligation device. All patients in the both groups were alive during the 3-year observation period.CONCLUSION: Endoscopic resection using a ligation device is a useful and safe method for resection of small rectal carcinoid tumors.

    BACKGROUND: Carcinoid tumors of the extrahepatic biliary tree are extremely rare malignancies, accounting for 0.2%-2%of all gastrointestinal carcinoid tumors, while carcinoids of the cystic duct are an uncommon entity and an extremely unusual cause of bile duct obstruction. METHODS: After an extensive literature review, we retrospectively analysed 61 cases of carcinoid tumor of the biliary tree as well as one additional case of a 60-year-old female with symptoms and laboratory/imaging examination ifndings compatible with those of a malignant biliary tract obstruction. At laparotomy, resection of the gallbladder and common bile duct was performed. Histological study revealed a well-differentiated neuro-endocrine carcinoma of the cystic duct. The patient remained disease-free at 16 months. RESULTS: Our presentation is the seventh case reported in the world literature. Compared to cholangiocarcinoma, analysis of the reviewed group indicates an increased incidence of extrahepatic carcinoid tumors in younger persons along with a slight female predominance. Statistically, the most common anatomic location is the common bile duct, followed by the perihilar region and the cystic duct. Jaundice is the most common ifnding. Curative surgery was realized in the majority of cases and long-term disease-free survival was achieved when surgery was curative. CONCLUSIONS: Carcinoid tumors obstructing the biliary tree are extremely dififcult to diagnose preoperatively, and nearly impossible to differentiate from non-neuroendocrine tumors. As surgery offers the only potential cure for both biliary carcinoids and cholangiocarcinoma, we recommend aggressive surgical therapy as the treatment of choice in every case of potentially resectable biliary tumor.

    Goblet cell carcinoid tumor of the appendix (GCTA) is a tumor with histological features of both adenocarcinoma and carcinoid tumors. The most common clinical presentation of GCTA is acute appendicitis, although small bowel obstruction has been reported as a rare clinical symptom of GCTA. However, to the best of our knowledge, the CT feature of small bowel obstructions in patients with GCTA has not been reported to date. Here, we present a case of small bowel obstruction in a patient with GCTA caused by extensive tumor infiltration at the terminal ileum and distal ileum.

  2. The role of somatostatin receptor scintigraphy in the diagnosis and treatment of carcinoid tumors

    International Nuclear Information System (INIS)

    Somatostatin receptor scintigraphy is a new fascinating approach in the diagnosis of carcinoid tumors. Using iodine-123 or indium-111 labeled somatostatin analogues, SRS turned out to be a highly sensitive diagnostic tool in the localization of primary tumors and their metastases. Due to the specifity of the receptor-ligand-binding and some distinct pharmacokinetic properties, SRS enables the localization of very small neuroendocrine tumors (≤1.5 cm) and the detection of previously unknown metastases. Based on previous reports in the literature and our own experience in 110 patient studies in carcinoid tumors, SRS can be recommended for (1) localizing primary neuroendocrine tumors; (2) determining the extent of the disease in endocrine carcinoids; (3) monitoring the further course of the disease.

    We report the case of a 49-year-old woman who presented a tailgut cyst lined by a variety of epithelium including squamous, columnar and transitional. Fortuitously a microscopic carcinoid tumor expressing immunohistochemically neuroendocrine markers was identified in the cystic wall. Tailgut cysts are congenital abnormalities located in the presacrococcygeal area occurring usually in adult patients. Clinical diagnosis is difficult because they are often asymptomatic. Patients may present symptoms resulting from local mass effects or complications. The differential diagnoses include rectal duplication cysts, cystic sacrococcygeal teratomas, epidermal cysts, epidermoid cysts, anal duct or gland cysts. Magnetic resonance imaging has recently become the modality of choice to image the cyst. Malignant transformation is rare; 23 cases including 10 carcinoid tumors have been reported in the literature. To our knowledge, this is the eleventh case of carcinoid tumor arising in a tailgut cyst. PMID:16136488

    A 45-year-old Japanese woman complained of uncontrolled hypertension and face swelling. She was diagnosed with Cushing's syndrome with secretion of adrenocorticotropic hormone. Fluorodeoxyglucose positron emission tomography-computed tomography revealed a 2 × 2 cm mass in her left lung, with high standardized maximum uptake value. She underwent bronchoscopy with endobronchial ultrasound via a guide-sheath. Surgical resection of her left upper lung was performed, and pathological examination showed a typical carcinoid tumor. After lung resection, she recovered from her subjective symptoms. Diagnosis of peripheral carcinoid tumor of the lung is generally difficult. Here, we introduce a case of peripheral pulmonary carcinoid tumor diagnosed by endobronchial-ultrasound-guided bronchoscopy. PMID:26839693

    We have encountered an unusual case of gastric carcinoid tumor. Gastroscopic examination of this 32-year-old male patient showed a smooth protrusion at the greater curvature of the gastric body with a central depression,identified by subsequent biopsy as carcinoma. The patient had a normal serum gastrin level and was negative for anti-parietal cell antibody. Histological examination of the resected gastric tissues showed that the tumor was a carcinoid, 0.3 cm×0.3 cm in size with only one regional lymph node metastasis. We reviewed the pathogenesis,clinical presentation, diagnosis and treatment of gastric carcinoids and raise the possibility of being a lymph vesselrelated metastasis even for a minute carcinoid tumor.Sentinel lymph node biopsy is recommended for surgery of minute carcinoid tumors.

    Cytologic findings of pulmonary carcinoid have been well described. We report new cytological findings in a case of carcinoid tumor. The patient is a 36-year-old man presenting with hemoptysis of about six months in duration. Chest CT scans showed a well-defined round polypoid lesion measuring 1 × 1 cm within the right upper lobe of the bronchus with hyperinflation of the right upper lobe. Trans-bronchial fine needle aspiration and biopsy were done. Cytologic smears showed isolated and loose clusters of uniform round to spindle shape cells with round centrally located nuclei, fine granular (salt and pepper) chromatin and pale cytoplasm. Intranuclear pseudo-inclusions and grooves were seen in some tumor cells. No mitotic figures or necrosis were evident. A cytological diagnosis of carcinoid tumor was made and histopathologic examination and subsequent immunohistochemical study confirmed the diagnosis. Carcinoid tumor may be reliably diagnosed on fine needle aspiration cytology smears. Intranuclear pseudo-inclusions and grooves may be evident in tumor cells. PMID:26838088

    Small-bowel carcinoid tumors are the most common form(42%) of gastrointestinal carcinoids, which by themselves comprise 70% of neuroendocrine tumors. Although primary small bowel neoplasms are overall rare(3%-6% of all gastrointestinal neoplasms), carcinoids still represent the second most common(20%-30%) primary small-bowel malignancy after small bowel adenocarcinoma. Their imaging evaluation is often challenging. State-of-the-art high-resolution multiphasic computed tomography together with advanced postprocessing methods provides an excellent tool for their depiction. The manifold interactive parameter choices however require knowledge of when to use which technique. Here, we discuss the imaging appearance and evaluation of duodenal, jejunal and ileal carcinoid tumors, including the imaging features of the primary tumor, locoregional mesenteric nodal metastases, and distant metastatic disease. A protocol for optimal lesion detection is presented, including the use of computed tomography enterography, volume acquisition, computed tomography angiography and three-dimensional mapping. Imaging findings are illustrated with a series of challenging cases which illustrate the spectrum of possible disease in the small bowel and mesentery, the range of possible appearances in the bowel itself on multiphase data and extraluminal findings such as the desmoplastic reaction in mesentery and hypervascular liver metastases. Typical imaging pitfalls and pearls are illustrated.

    Twelve cases of carcinoid tumors of the thymus were reviewed in terms of clinicopathologic, histochemical, and immunohistochemical features and DNA ploidy patterns. The collective consisted of nine male and three female patients, aged 34 to 74 years, of whom five (42%) had symptoms. Eleven patients underwent surgical resection, and one with systemic metastases was autopsied. In the 11 resected patients, tumors had invaded surrounding structures in four cases, and mediastinal lymph node metastases were detected in six. Recurrence occurred in two of the resected patients (18%), and the 5-year survival rate was 82%. Histologically, all tumors showed an organoid growth pattern with delicate fibrovascular stroma. In addition, three tumors had unusual morphologic features such as combined features of carcinoid tumor and thymoma and solid growth pattern with occasional large tumor cells. Mitotic counts ranged from 1 to 14 per 10 high-power fields with a mean count of 4.9. Central necrosis within solid nests was observed in nine tumors. Classification of this series using the WHO histologic classification system resulted in categorization of all 12 tumors as atypical carcinoids. All tumors were positive for Grimelius staining and for cytokeratin. Immunohistochemical staining documented the presence of moderately to strongly positive neuroendocrine markers such as neuron-specific enolase, chromogranin A, synaptophysin, and neural cell adhesion molecule. No correlation between proliferative activity based on the Ki67 labeling index and prognosis or lymph node metastasis was found. Concerning DNA ploidy patterns, only one tumor with multiple lymph node metastases was considered to be aneuploid. In conclusion, although all of our cases were histologically classified as atypical carcinoid tumors of the thymus, most were diploid, and the patients enjoyed a relatively good prognosis.

    Full Text Available We report a primary hepatic carcinoid tumor occurring in a 47-year-old man. The patient consulted our hospital complaining of epigastralgia. Abdominal ultrasonography, computed tomography scanning, and magnetic resonance imaging showed a large mass in the right lobe of the liver. FDG-PET revealed 18F-FDG uptake by the right hepatic lobe. The tumor was a solid mass with cystic components, approximately 15 cm in diameter. We conducted an extended right lobectomy of the liver. The resected specimen was a solid tumor with cystic components and hemorrhagic lesion. Microscopic findings showed that the tumor cells had round nuclei and formed trabecular patterns. Immunohistologically, tumor cells were stained positive for chromogranin A, neuron specific enolase, CD56, and S-100. Careful examinations before and after the operation revealed no other possible origin of the tumor. Based on these findings, the tumor was diagnosed as a primary hepatic carcinoid. This is a report of a rare case of a primary hepatic carcinoid tumor with a discussion of several other relevant reports.

    A man in his early thirties presented to our clinic with right lower abdominal pain. Computed tomography (CT) and ultrasonography (US) revealed a swollen appendix and an appendicolith. Abscess formation was not observed but ongoing appendiceal rupture was not ruled out. Three months after successful conservative therapy, the lumen of the apical portion was kept dilated and laparoscopic interval appendectomy was performed. No tumorous findings were observed macroscopically. However, histology revealed many tiny nests infiltrating the submucosa, muscular layer, and subserosa at the root of the appendix. An appendiceal neuroendocrine tumor G1 (NET G1; carcinoid) was diagnosed immunohistologically. Neither CT nor US visualized the tumor because of its non-tumor-forming but infiltrative growth. In conclusion, after successful conservative treatment, interval appendectomy should be considered to uncover a possible appendiceal NET G1 (carcinoid), particularly when dilatation of the distal lumen is kept under observation.

    Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate. The shortcomings of this method are the inability to fix the knife to the target lesion, and compression of the lesion. These can lead to major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using electrosurgical current. Colonoscopy on a 55-year-old woman revealed a 10-mm rectal submucosal nodule. The histological diagnosis of the specimen obtained by biopsy was carcinoid tumor. Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement. It was safely and accurately resected without unexpected incision by ESD using a GSF. No delayed hemorrhage or perforation occurred. Histological examination confirmed the carcinoid tumor was completely excised with negative resection margin.

    2008-01-01

    Van Hippel-Lindau syndrome (VHL) is a rare autosomal dominant, inherited familial cancer syndrome. Hemangioblastomas, pheochromocytomas and renal carcinoma are the frequent reported VHL tumors. Neuroendocrine tumors have also been described, mostly in the pancreas and rarely in the biliary trees. We report the second case of bile duct carcinoid in a 31-year-old VHL woman. She underwent right adrenalectomy for a pheochromocytoma in the past. She also had a positive family history of phenotypic expression of VHL syndrome. The patient presented with biliary colic. Endoscopic retrograde cholangio-pancreatography showed intra luminal bile duct mass. Surgical exploration identified a beige nodular lesion that was a carcinoid tumor on histology. This new association should be clarified by further genetic investigations.

    Full Text Available Abstract Background Carcinoid tumors are characteristically low grade malignant neoplasms with neuroendocrine differentiation that arise in various body sites, most commonly the lung and gastrointestinal tract, but less frequently the kidneys, breasts, ovaries, testes, prostate and other locations. We report a case of a carcinoid of renal origin with synchronous single liver metastases on radiological studies. Case presentation A 45 year-old patient who presented with abdominal pain was found on CT scan to have lesions in the right ovary, right kidney, and left hepatic lobe. CA-125, CEA, and CA 19-9 were within normal limits, as were preoperative liver function tests and renal function. Biopsy of the liver mass demonstrated metastatic neuroendocrine tumor. At laparotomy, the patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, radical right nephrectomy with lymphadenectomy, and left hepatectomy. Pathology evaluation reported a right ovarian borderline serous tumor, well-differentiated neuroendocrine carcinoma of the kidney (carcinoid with 2 positive retroperitoneal lymph nodes, and a single liver metastasis. Immunohistochemistry revealed that this lesion was positive for synaptophysin and CD56, but negative for chromogranin as well as CD10, CD7, and CD20, consistent with a well-differentiated neuroendocrine tumor. She is doing well one year after her initial surgery, with no evidence of tumor recurrence. Conclusion Early surgical intervention, together with careful surveillance and follow-up, can achieve successful long-term outcomes in patients with this rare malignancy.

    AIM: To report the experience of the CHU Sart Tilman,appendiceal carinoid tumor.METHODS: A retrospective review of 1237 appendectomies performed in one single centre from January 2000 to May 2004, was undertaken. Analysis of demographic data, clinical presentation, histopathology, operative reports and outcome was presented.RESULTS: Among the 1237 appendectomies, 5 appendiceal carcinoid tumors were identified (0.4%) in 4 male and 1 female patients, with a mean age of 29.2 years (range: 6-82 years). Acute appendicitis was the clinical presentation for all patients. Four patients underwent open appendectomy and one a laparoscopic procedure.One patient was reoperated to complete the excision of mesoappendix. All tumors were located at the tip of the appendix with a mean diameter of 0.6 cm (range: 0.3-1.0cm). No adjuvant therapy was performed. All patients were alive and disease-free during a mean follow-up of 33 mo.CONCLUSION: Appendiceal carcinoid tumor most often presents as appendicitis. In most cases, it is found incidentally during appendectomies and its diagnosis is rarely suspected before histological examination. Appendiceal carcinoid tumor can be managed by simple appendectomy and resection of the mesoappendix, if its size is ≤ 1cm.

    Full Text Available Context Duodenal carcinoids are extremely rare, and their characteristics and biological behavior have not been fully elucidated. Objective To analyze the clinicopathological characteristics of patients with resected duodenal carcinoids. Methods Twenty patients (12 females and 8 males were investigated. Their average age was 66.4 ± 5.8 years old (43 to 88 years old. The data corresponding to the clinical picture, diagnosis, treatment, and prognosis of patients with duodenal carcinoid tumors subjected to resection over a period of 18 years (1993-2011 were analyzed. Results The most common symptoms were dyspepsia (50% and epigastric pain (45% followed by weight loss (10% and vomiting (5%. Carcinoid syndrome was not observed in any patient. The lesion was located on the first part of the duodenum in 15 (75% patients, the second part in 4 (20% patients, and the third part in 1 (5% patient. The diagnosis of a carcinoid tumor was established through an endoscopic excision biopsy in 19 (95% patients and an histopathological examination of the surgical specimen in 1 (5% patient. The average tumor size was 1.1 cm ± 0.4 cm (0.3 cm to 6.0 cm. Nineteen (95% patients were initially treated by endoscopic resection of the duodenal lesion. One patient (5%, whose tumor was on the third part of the duodenum underwent a duodenectomy of the third and fourth duodenal parts and duodenojejunal anastomosis. The duodenal carcinoid resection margin was involved in four (20% patients. Four (20% patients were subjected to a partial gastrectomy to fully remove the lesion. The tumor was restricted to the submucosal layer in 16 (80% cases, and it penetrated into the muscular layer in 4 (20% cases. All patients exhibited positive chromogranin A, neuron-specific enolase, and/or synaptophysin immunostaining. The average duration of the follow-up period was 39.6 months (3 to 96 months.

    Antecedentes: los tumores apendiculares se encuentran en cerca de 1% de las apendicectomías y representan 0.5% de las neoplasias intestinales. El tipo de tumor más frecuente es el carcinoide apendicular, que casi siempre es un hallazgo durante la apendicectomía por otro motivo. Su pronóstico es excelente y la supervivencia es mayor de 95% a cinco años de la intervención. Objetivo: reportar una serie de casos y analizar la supervivencia media a cinco años posteriores a la identificación el tumor. Material y métodos: análisis retrospectivo (1990-2010) de pacientes con tumor carcinoide apendicular intervenidos en el servicio de Cirugía General y del Aparato Digestivo del Hospital Universitario Virgen del Rocío, Sevilla, España. Se analizaron: la supervivencia a cinco años, la necesidad de tratamiento complementario y las pruebas para seguimiento en la consulta. Resultados: se encontraron 42 pacientes intervenidos por tener un tumor carcinoide apendicular. En 38 pacientes la operación fue de urgencia, la mayoría por sospecha de apendicitis aguda, sin que en ninguno se hubiera establecido el diagnóstico de tumor carcinoide antes de la operación. El síntoma predominante al ingreso fue el dolor abdominal. El tratamiento quirúrgico fue: apendicectomía en 34 pacientes (12 por laparoscopia), en el intraoperatorio siete pacientes requirieron resecciones colónicas mayores debido a la afectación del colon; sólo uno requirió la reintervención para completar la hemicolectomía derecha. Al momento del diagnóstico dos pacientes tenían enfermedad diseminada (metástasis hepáticas). La supervivencia a cinco años fue superior a 95%, sin recidivas o tratamiento posterior de la enfermedad. Conclusiones: el tumor carcinoide apendicular difícilmente se diagnostica antes del procedimiento quirúrgico. La apendicectomía suele ser suficiente aunque en algunos pacientes las resecciones colónicas son necesarias por diseminación. La supervivencia a 5 años es

    We report a patient with a hepatic neuroendocrine tumor showing an extraordinary change of the tumor's humoral manifestations from a clinically documented extrapituitary acromegaly and a typical carcinoid syndrome toward a hyperinsulinemic hypoglycemia syndrome. At the primary manifestation of the tumor, an increased serum level of insulin-like growth factor I due to overproduction of GHRH and an increased urinary excretion of 5-hydroxyindoleacetic acid were found. The clinical manifestation of the GHRH excess was an arthralgia, which resolved completely after operative tumor debulking and normalization of insulin-like growth factor I and GHRH serum levels. The secretion of serotonin from the tumor resulted in a typical carcinoid syndrome including right-sided valvular heart disease. On the later course of the disease, the humoral manifestations of the tumor were supplemented by the secretion of insulin, leading to recurrent severe hyperinsulinemic hypoglycemia. The hepatic origin of hyperinsulinism was demonstrated by selective arterial calcium stimulation. Moreover, tumor cells revealed insulin and C-peptide immunoreactivity in the immunohistochemical analysis. The patient died 8 yr after the initial diagnosis of the tumor, and a carefully performed autopsy procedure confirmed the absence of any extrahepatic tumor manifestation.

    Full Text Available Introduction. Coexistence of carcinoid tumor inside a mature cystic teratoma is an extremely rare phenomenon, especially in young women. We present the case of a 28-year-old woman diagnosed with a right ovarian carcinoid and treated uneventfully with conservative surgical approach. Case Report. A 28-year-old woman, gravid 0, parity 0, presented to our department for her annual gynecological examination and Pap smear test. During her examination, a mobile cystic mass was detected in the right lower abdomen. Ultrasound indicated a right ovarian mass 10.5 × 6.3 cm, confirmed by CT scan. Further investigation revealed AFP levels (1539 ng/mL. The ovarian mass was excised by laparoscopy, leaving intact the remaining right ovary. Frozen sections showed a mature cystic teratoma. However, paraffin sections revealed the presence of a small carcinoid within the teratoma’s gastric-type mucosa. The patient was set to a close followup. Nine months postoperatively, ultrasound pelvis imaging and CT scan of the abdomen as well as serum tumor markers have shown no evidence of recurrence disease. Conclusion. Despite the weak evidence, fertility spare surgical approach for women wanting to preserve their genital tract might be a reasonable option.

    Tailgut cysts are uncommon developmental cysts that form in the presacral space. Complications of tailgut cysts include benign reactive lesions associated with infection and inflammation, and malignant transformation. Six cases of carcinoid tumor arising in tailgut cysts have been reported in the medical literature to date. Here we report another case of carcinoid tumor arising in a tailgut cyst. Because six of seven cases occurred in females, we postulate that these tumors are hormone-associated. This hypothesis is supported by the present study. We found strong estrogen receptor immunoreactivity of the benign squamous and columnar cyst-lining cells as well as carcinoid tumor cells, in addition to neuroendocrine differentiation in the tumor cells and scattered cyst-lining cells. We speculate that estrogen receptor may be a potential therapeutic target in patients with this condition. PMID:18787681

    Full Text Available Abstract Background Primary carcinoid tumor arising within mature teratoma of the kidney is extremely rare, and their clinicopathologic features are not well described. Our objective was to further define the clinical features and pathologic spectra of primary carcinoid tumor arising within mature teratoma of the kidney. Methods Six previously reported case reports were identified using MEDLINE and a subsequent bibliographic search of all pertinent reports and reviews was performed. We also searched the electronic medical archival records of our institution and identified one additional unreported case. Data were extracted on the demographics, predisposing factors, clinical presentation, radiographic features, gross pathology, microscopic pathology, immunophenotype, therapy, and outcome of each of these seven cases. Results Primary carcinoid tumor arising within mature teratoma of the kidney was found at a mean age of 41.4 years. Of the 7 cases, 3 were female and 4 were male. Two of the 7 cases (28.6% were associated with horseshoe kidney. It typically presented with abdominal pain without carcinoid syndrome. It typical radiologic appearance was well circumscribed partly calcified Bosniak II-III lesion. Histologically, the carcinoid tumor showed monotonous small round cells arranged in classic anastomosing cords/ribbons intermixed with solid nests. Surgery was curative, no additional treatment was required, no local recurrences occurred, and no metastases occurred in all 7 cases. The 3 cases with available outcome data were alive at the time of publication of their respective cases (mean, 5 months. Conclusion Primary carcinoid tumor arising within mature teratoma of the kidney is a rare tumor that typically presents with abdominal pain without carcinoid syndrome. It is not associated with local recurrence and metastasis, is surgically curable, and has excellent prognosis.

    Middle ear carcinoid tumor (MEC T) is rare. Only 46 cases of MECT have been reported in the literature since the first case of MECT was described in 1980. We present here a case of primary MECT initially diagnosed as inflammatory aural polyp. The case was a 43-year-old women complaining of right ear chronic otorrhea and hearing loss over a period of five years, with a blockage sensation in the right ear for two years. Audiometry showed conductive hearing loss in the right ear. Physical examination and CT scans showed a mass in the right external auditory canal and middle ear, surrounding the ossicular chain. Pathologic study of surgically removed specimen revealed features of carcinoid tumor with positive staining to chromogranin A and synaptophysin in tumor cells. Local radiation of 60 Gy was applied. The patient has been followed up for more than one year. Postoperative histopathological examination showed no evidence of MECT recurrence one year after surgery, but inflammatory changes in the middle ear. Relevant literatures were reviewed. Clinical, histopathological, immunohistochemical and ultrastructural features of MECT, and strategies in MECT diagnosis and management are discussed.

El paciente era un varón de 64 años con historia reciente de diarreas al que se diagnosticó una ictericia obstructiva. Histopatológicamente el tumor resecado mostraba dos neoplasias independientes. Una de ellas constituida por cordones sólidos de células neuroendocrinas que afectaba pared duodenal. La otra está formada por un adenocarcinoma bien diferenciado procedente del páncreas. Ambas neoplasias fueron confirmadas inmunohistoquímicamente. Según la literatura anglosajona revisada tan sólo hemos encontrado seis casos de esta rara coexistencia neoplásica.We report the case of a periampullary collision tumor, in which a duodenal-wall carcinoid and an adenocarcinoma of the head of the pancreas coexisted. We describe the case of a 64-year-old man with a recent history of diarrhea, who was diagnosed with obstructive jaundice. A duodeno-pancreatectomy was performed, and the specimen showed two independent neoplasms in the histopathologic study. Solid cords and nests of neuroendocrine cells in the duodenal wall formed the carcinoid tumor, whereas the other neoplasm was made up of a well-differentiated adenocarcinoma of the pancreas. Both were confirmed by immunohistochemical analysis. According to the literature reviewed, this is the sixth reported case of this rare neoplastic association.

    Somatostatin receptors have been identified in many tissues throughout the human body. Alterations in the expression of somatostatin receptors have been reported in many disease states including both tumorous and nontumorous conditions. Somatostatin receptor scintigraphy utilizing OctreoScan (Mallinckrodt Medical, Inc., St. Louis, MO), a radiolabled form of octreotide, has been reported to be a highly sensitive imaging technique for identifying pathology, such as neuroendocrine tumors, that are somatostatin receptor dense. Unfortunately, many conditions cause an increase in the quantity of somatostatin receptors and therefore may cause false positive Octreoscans. In this report, we discuss the alterations in somatostatin receptors that occur with Crohn's disease and describe a case of an OctreoScan-positive inflammatory mass mimicking a carcinoid tumor.

    SS receptors are overexpressed in many tumors, mainly of neuroendocrine origin, thus enabling the treatment with SS analogs. The clinical experience of receptor radionuclide therapy with the new analog [90Y-DOTA0-Tyr3 ]-octreotide [90Y-DOTATOC] has been developed over the last decade and is gaining a pivotal role in the therapeutic workout of these tumors. It is well known that some procedures performed in diagnostic and therapeutic management of endocrine tumors, such as agobiopsy and hepatic chemoembolization, can be associated with the occurrence of symptoms related to the release of vasoactive amines and/or hormonal peptides from tumor cell lysis. This is the first report of a severe carcinoid crisis developed after receptor radionuclide therapy with 90Y-DOTATOC administered in a patient affected by liver metastases from bronchial neuroendocrine tumor (atypical carcinoid). Despite protection with H1 receptor antagonists, octreotide and corticosteroids, few days after the therapy the patient complained of persistent flushing of the face and upper trunk, severe labial and periocular oedema, diarrhoea and loss of appetite. These symptoms increased and required new hospitalisation. The patient received iv infusion of octreotide associated with H1 and H2 receptor antagonists and corticosteroid therapy, which induced symptom remission within few days. The case here reported confirms that radionuclide therapy is highly effective in determining early rupture of metastatic tissue and also suggests that pre-medication should be implemented before the radiopeptide administration associated with a close monitoring of the patient in the following days.

    Full Text Available Surgical resection is the first choice for treatment of a thymic carcinoid tumor and radiotherapy is often performed as adjuvant therapy. Here, we report a case of an unresectable and chemoresistant thymic carcinoid tumor that was treated successfully using standalone proton beam therapy (PBT. The patient was a 66-year-old woman in whom surgical resection of the tumor was impossible because of cardiac invasion. Therefore, chemotherapy was administered. However, the tumor grew to 15 cm in diameter and she developed severe superior vena cava (SVC syndrome. She was referred to our hospital and received PBT at a dose of 74 GyE in 37 fractions. PBT was conducted without severe early toxicities. After PBT, the tumor mildly shrunk to 13 cm in diameter and SVC syndrome almost disappeared. Subsequently, the tumor has continued to decrease in size slowly over the last 2 years and late toxicities have not been observed. Our experience with this case suggests that PBT may be effective for an unresectable thymic carcinoid tumor.

    Full Text Available Abstract Background Overdiagnosis of bronchopulmonary carcinoid tumors together with overtreatment can cause serious postoperative consequences for the patient. We report of a patient with a typical bronchopulmonary carcinoid tumor, which was initially misdiagnosed and treated as an adenocarcinoma of the lung. GnrH receptors and the associated Raf-1/MEK/ERK-1/2-pathway are potential targets for analogs in cancer treatment. We suspected a correlation between the lack of tumor growth, application of leuprolide and the Raf-1/MEK/ERK-1/2-pathway. Therefore, we examined GnrH receptor status in the examined specimen. Case presentation In 2010 a 77 year-old male patient was shown to have a tumor mass of about 1.7 cm diameter in the inferior lobe of the left lung. Since 2005, this tumor had hitherto been known and showed no progression in size. The patient suffered from prostate cancer 4 years ago and was treated with TUR-P, radiation therapy and the application of leuprolide. We conducted an explorative thoracotomy with atypical segment resection. The first histological diagnosis was a metastasis of prostate cancer with lymphangiosis carcinomatosa. After several immunohistochemical stainings, the diagnosis was changed to adenocarcinoma of the lung. We conducted a re-thoracotomy with lobectomy and systematic lymphadenectomy 12 days later. The tumor stage was pT1 N0 MX G2 L1 V0 R0. Further immunohistochemical studies were performed. We received the results 15 days after the last operation. The diagnosis was ultimately changed to typical carcinoid tumor without any signs of lymphatic vessel invasion. The patient recovered well from surgery, but still suffers from dyspnea and lack of physical performance. Lung function testing revealed no evidence of impairment. Conclusion The use of several immunohistochemical markers, careful evaluation of hematoxylin-eosin sections and the Ki-67 labelling index are important tools in discriminating between carcinoids

    Pulmonary carcinoid tumor with Cushing's syndrome is comparatively rare disease. It is difficult to make an early diagnosis due to small size lesion in its early stage. We report a case of pulmonary carcinoid tumor with Cushing's syndrome successfully localised by positron emission tomography/computed tomography and was resected in the early stage. The levels of serum cortisol and adrenocorticotropic hormone( ACTH) decreased immediately after surgery, and the symptoms of Cushing's syndrome were relieved.

    Strumal carcinoid develops in a germ cell tumor characterized by an intimate mixture of thyroid and carcinoid. Unlike other carcinoid tumors, most patients with strumal carcinoid have no symptoms of carcinoid syndrome; few are reported to cause severe constipation. We report a case of a 60-year-old female patient presenting with severe progressive constipation and painful defecation for last few years. A right ovarian tumor was discovered during clinical examination. CT scan revealed a large ...

    Full Text Available Abstract Carcinoid is a rare malignancy originating from enterochromaffin cells and is clinically characterized by flushing, diarrhea and bronchospasm, due to secretion of vasoactive substances. A dreaded complication is carcinoid heart disease, which mainly affects right cardiac chambers, resulting in thickened, immobile and retracted tricuspid and pulmonary valves. In the current report, a case of a 60-year old female presenting with symptoms of right heart failure is described. Transthoracic two-dimensional and real-time three-dimensional echocardiography findings, as well as biochemical markers, including pro-BNP and NT-pro-BNP, were consistent with carcinoid syndrome. The histological diagnosis of carcinoid was confirmed after surgical resection of an ovarian mass.

    Full Text Available Introduction: usually found in the gastrointestinal tract, carcinoids are the most frequent neuroendocrine tumors. Most of these lesions are located in areas that are difficult to access using conventional endoscopy (small intestine and appendix; carcinoid tumors found in the gastroduodenal tract and in the large intestine can be studied endoscopically; in these cases, if localized disease is confirmed, local treatment by endoscopic resection may be the treatment of choice. Since endoscopic ultrasonography has been shown to be the technique of choice for the study of tumors exhibiting submucosal growth, the selection of patients who are candidates for a safe and effective local resection should be based on this technique. Patients and method: we selected patients with gastrointestinal carcinoid tumors who were endoscopically treated between 1997 and 2002. Those patients with tumors measuring less than 10 mm, which had not penetrated the muscularis propria, and those with localized disease were considered candidates for endoscopic resection. The endpoints of this study were to assess the effectiveness (complete resection and safety (complications of the technique. Follow-up consisted of eschar biopsies performed one month and twelve months after the resection. Results: during the aforementioned period, we resected endoscopically 24 tumors in 21 patients (mean age: 51.7 years; 71.5% males. Most lesions were incidental discoveries made during examinations indicated for other reasons. Resection was indicated in most cases as a result of the suspected presence of a carcinoid tumor after endoscopic ultrasonography. Endoscopic ultrasonography also enabled us to clearly identify the layer where the lesion had originated, as well as the size of the lesion. The carcinoid tumor was removed in 13 cases (54.2% by using the conventional snare polypectomy technique, in 9 cases (37.5% assisted by a submucosal injection of saline solution and/or adrenaline, and

    Tailgut cysts are developmental hamartomas found in the presacral space. They are usually detected incidentally during physical examinations or imaging studies. However, they may cause symptoms due to compression of nearby organs. Due to their potential malignant transformation, surgical resection is warranted, while routine biopsy is considered controversial because of the concern about infection of the tailgut cyst and needle-track implantation of malignant cells. The co-existence of a carcinoid in a tailgut cyst is extremely rare. Only 16 cases have been reported previously, the vast majority of which were found in females. We herein present the case of a carcinoid in a tailgut cyst found in a male patient, discuss the potential pathogenesis of tailgut carcinoids, and underline the fact that their previous consideration of the condition as a female-restricted entity should be rejected.

    Bronchial carcinoid tumors are neuroendocrine neoplasms capable of expressing somatostatin receptors and of secreting neuromediators such as ACTH and chromogranins. Radiologic appearance is usually non-specific and has to be distinguished from benign pulmonary nodules and other malignant diseases. Standard radiological techniques have limited accuracy in the evaluation of such lesions. Radioisotopic imaging techniques may increase the specificity of diagnostic assessment. The role of immunoscintigraphy with anti-chromogranin A and B monoclonal antibodies (MoAbs) and of 111In-Octreoscan scintigraphy is evaluated in two cases of bronchial carcinoid tumors associated to Cushing syndrome.

    Neuroendocrine tumors (NETs; syn. carcinoid tumors) are highly or moderately differentiated neoplasms. They comprise a large variety of rare and heterogeneous tumors with an estimated incidence of 3-5/100,000/year. They can arise in virtually every internal organ, but mainly occur in the gastroenteropancreatic and bronchopulmonary systems. Around 25% of the NETs are localized in the bronchopulmonary system. Approximately 2% of all lung tumors are NETs. According to the World Health Organization (WHO) classification of lung tumors, bronchopulmonary NETs are subdivided into typical carcinoids (TCs) and atypical carcinoids (ACs). The parameter with the highest impact on NET behavior and prognosis is the histological classification and staging according to the tumor/node/metastasis (TNM) system. The diagnosis of NETs is established by histological examination and the immunohistochemical detection of general neuroendocrine markers, such as chromogranin A (CgA) and synaptophysin. Serum markers and the use of functional imaging techniques are important additive tools to establish the diagnosis of a NET. The only curative option for lung NETs is complete surgical resection. Beyond that, the currently available interdisciplinary therapeutic options are local ablation, biotherapy (somatostatin analogues), or chemotherapy. New therapeutic options such as peptide receptor radionuclide therapy (PRRT) and molecularly targeted therapies achieve promising results and are under further evaluation. This report is a consensus summary of the interdisciplinary symposium 'Neuroendocrine Tumors of the Lung and of the Gastroenteropancreatic System (GEP NET) - Expert Dialogue' held on February 25-26, 2011 in Weimar, Germany. At this conference, a panel of 23 German experts shared their knowledge and exchanged their thoughts about research, diagnosis, and clinical management of NETs, whereby special attention was paid to NETs of the respiratory tract.

    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin. Additionally, the

    Well-differentiated neuroendocrine tumors (carcinoids) arising in the presacral space are rare neoplasms that can arise in association with either sacrococcygeal teratomas or tailgut cysts. Although tumors arising in tailgut cysts are more frequent than those associated with teratomas, they are still very rare, and only 13 cases have been reported in the literature. We describe the first case of a carcinoid composed of ghrelin-producing cells arising in a tailgut cyst. Ghrelin production was demonstrated using immunohistochemistry, electron microscopy, and reverse transcription-polymerase chain reaction methods. A 73-year-old woman with back and pelvic pain was found to have a presacral mass histologically diagnosed, on needle biopsy, as a well-differentiated neuroendocrine tumor. Workup did not show another primary tumor or metastatic disease. The patient underwent laparoscopic resection of the mass, and the pathological diagnosis of the surgical specimen was of a tailgut cyst-associated carcinoid composed of ghrelin-producing cells. In addition, we have accurately reviewed the literature on presacral carcinoids, associated or unassociated with tailgut cysts, to give the reader a comprehensive overview of these very rare tumor types.

    Tailgut cyst is a rare congenital presacral lesion and is believed to arise from the persistent remnants of the postanal gut. Malignancy occurring in a tailgut cyst is extremely rare, and to our knowledge only 5 cases of carcinoid tumor arising in a tailgut cyst have been reported in the literature to date. We report a sixth case of carcinoid tumor arising in a tailgut cyst. The patient was a 41-year-old woman who presented with perianal pain. Sigmoidoscopy showed a 2-cm submucosal mass located 4 cm above the anal verge. The mass was a multilocular cyst with gray-tan solid portions. The cyst was lined by ciliated columnar, squamous, and transitional epithelia with small foci of carcinoid tumor in the cystic wall. The carcinoid tumor showed a trabecular growth pattern with uniform oval or round cells containing fine chromatin and positive immunoreactivity for chromogranin, synaptophysin, and cytokeratin. This case was unique because the tumor occurred at the anorectal junction, not in the retrorectal space, and unlike previously reported cases showed aggressive behavior and distant metastases.

  5. Biokinetics of 111In-DTPA-D-Phe1-octreotide in nude mice transplanted with a human carcinoid tumor

    International Nuclear Information System (INIS)

    The long time biokinetics of the radiolabeled somatostatin analogues 111In-DTPA-D-Phe1-octreotide was studied in nude mice transplanted with the human carcinoid tumor, GOT1. The results were compared with those from the patient with the original tumor. This patient has been diagnosed and later treated with 111In-DTPA-D-Phe1-octreotide. The animals received about 2 MBq 111In-DTPA-D-Phe1-octreotide (0.1 μg) by injection into a tail vein. The animals were killed 0.5 h-14 d after injection of the radiopharmaceutical. Tumor tissue and normal tissues were collected and weighed and measured for 111In activity. The 111In uptake in the tumor was higher than in all normal tissues except the kidneys. The tumor-to-normal-tissue activity concentration, TNC, increased with time for all normal tissues studied. These data were similar to those observed for the original tumor in the patient. The similar biokinetics for 111In-DTPA-D-Phe1-octreotide in the tumor-bearing mice and the patient makes this animal model suitable as a model for evaluation of therapy of somatostatin receptor (sstr) expressing tumors with radiolabeled somatostatin analogues. Furthermore, the increase with time of TNC both in mice and the patient indicates that long-lived radionuclides are preferred for therapy with radiolabeled somatostatin analogues

    Full Text Available Ovarian teratomas rarely undergo new neoplastic transformation and account for a small percentage of malignant ovarian germ cell neoplasms. Here we report a case of a 51-year-old woman with multiple endocrine neoplasia type I (MEN I who was found to have an ependymoma and neuroendocrine tumor (trabecular carcinoid associated with mature cystic teratoma of her left ovary. The ependymoma component displayed cells with round nuclei and occasional small nucleoli which were focally arranged in perivascular pseudorosettes and true rosettes. Rare mitoses were identified. No necrosis was present. Immunohistochemical staining was positive for S-100 and GFAP. The Ki67 proliferation index was very low (2-3%. In contrast, the endocrine tumor component was composed of small uniform cells with eosinophilic cytoplasm, round nuclei, and speckled chromatin. Immunohistochemical staining was positive for synaptophysin and focally positive for chromogranin. This rare case illustrates that MEN I may have an influence on the pathogenesis of ovarian teratomas as they undergo malignant transformation.

    2009-01-01

    Full Text Available Introduction. Carcinoid tumors are very common tumors of gastro-intestinal tract even though they are very rare in pancreatic area. A large number of patients with pancreatic carcinoma have non-specific symptoms of disease which is the main cause of late operative treatment of advanced tumors as well as for a low rate of 5-years surviving (28,9%±16%. Case report. A 69-year-old female patient was operated for a 7 cm large carcinoid in pancreatic corpus. Prior to the operation the patient did not have any symptoms of disease. Serotonin and 5-HIAA level was normal before the operation as well as afterwards. In this case distal hemipancreatectomy was done along with celiac, hepatic and lienal lymphadenoctomy. Liver metastasis was not found. The diagnosis of carcinoid was varified by postoperative histopathologic and imunohistochemical analysis. Discussion. According to the experience of other authors, the operative treatment of pancreatic carcinoid is very often undertaken when dimensions of tumor exceed 7 cm. In this stage of disease distant metastases are present in more than 60% of patients. Only 23% of examinated patients have had carcinoid syndrome symptoms. According to this conclusion, the main role of diagnostic procedures is attributed to the computer tomography of abdomen as well as ERCP. The radical resection of pancreas with lympahdenectomy is recommended in order to have a precise histological examination and detect occult lymph node metastases. With radical surgical procedures even at this stage of disease the operation may be curative. Conclusion. Any kind of radical surgical treatment (depending of localizations of tumor, proximal or distal is the main therapeutic procedure in pancreatic carcinoid.

    Full Text Available Abstract Introduction The diagnostic efficacy of somatostatin receptor scintigraphy labeling with 111 indium in the localization of tumors has been assessed in a limited number of patients with contradictory outcomes. Here, we describe the case of a patient with an ectopic adrenocorticotropic hormone-producing bronchial carcinoid tumor diagnosed preoperatively using technetium-99m-labeled octreotide acetate scintigraphy. Case presentation A 29-year-old Asian man presented to our hospital with the typical clinical features of Cushing's syndrome, which he had had for a duration of 18 months. The results of a biochemical evaluation revealed he had adrenocorticotropic hormone-dependent Cushing's syndrome. The results of a spiral abdominal computed tomography scan showed he had bilateral adrenal hypertrophy. A magnetic resonance image of the patient's brain showed he had a normal hypophysis. Whole body technetium-99m-labeled octreotide acetate scintigraphy was performed to check for the presence of an ectopic adrenocorticotropic hormone-producing tumor. The scan results showed a small focal increase in uptake in the lower lobe of our patient's right lung, just above his diaphragm. A spiral chest computed tomography scan also revealed a small non-specific lesion in the same region. A transthoracic biopsy was then performed. Pathological evaluation confirmed the diagnosis of a carcinoid tumor, of the adrenocorticotropic hormone-producing type. After surgical removal, the patient's symptoms resolved and significant clinical improvement was achieved. Conclusions This case report shows that technetium-99m-labeled octreotide acetate scintigraphy can effectively detect an ectopic adrenocorticotropic hormone-producing bronchial carcinoid.

    Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology but with an age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment area of the cases. Histological review performed by a reference pathologist left 99 cases for study; 84 cases and 2070 population controls were interviewed. The industries most closely associated (a twofold or more odds ratio [OR]) with SBC, taking into account a 10-year time lag after exposure were, among women, employment in wholesale industry of food and beverages (OR, 8.2; 95% confidence interval [CI], 1.9 to 34.9]) and among men, manufacture of motor vehicle bodies (OR, 5.2; 95% CI, 1.2 to 22.4), footwear (OR, 3.9; 95% CI, 0.9 to 16.1), and metal structures (OR, 3.3; 95% CI, 1.0 to 10.4). The identified high-risk occupations with an OR above 2 were shoemakers, structural metal preparers, construction painters and other construction workers, bookkeepers, machine fitters, and welders (men). The OR for regular occupational use of organic solvents for at least half a year was 2.0 (95% CI, 1.0 to 4.2). Exposure to rust-preventive paint containing lead was suggested as another potential occupational exposure (OR, 9.1; 95% CI, 0.8 to 107). This explorative study suggests an association between certain occupational exposures and SBC, but some of these associations could be attributable to chance. All findings should be regarded as tentative. PMID:12085477

    General introduction Carcinoids are rare slowly growing, neuroendocrine tumors. In 1907 Obendorfer was the first to use the term carcinoid (Karzinoide)1. He described an ileal tumor with a much slower progression than expected from denocarcinomas. The traditional classification of the carcinoids according to their embryonal site of origin was introduced in 1963.2 It comprises foregut-(in the lung, thymus, stomach, pancreas and proximal duodenum) midgut- (from the distal duodenum to proximal c...

    Central nervous system (CNS) tumors are the most common solid neoplasms in childhood and the second most common malignancies after leukemia in the pediatric age group. Supratentorial tumors are more common in children younger than 2 years old and in adolescents, whereas in patients between 2 and 12 years of age brain tumors originating in the posterior fossa dominate. This implies a relationship between the type of tumor, its location and the age of the patient, which has to be considered in differential diagnoses. Medulloblastoma represents the most common malignant brain tumor in childhood. In the posterior fossa medulloblastomas are approximately as frequent as astrocytomas. Supratentorial astrocytomas are by far the main tumor type. In this report some typical CNS neoplasms in children are discussed and their neuroradiological features are demonstrated. (orig.) [German] Hirntumoren sind die haeufigsten soliden Tumoren des Kindesalters und repraesentieren nach den Leukaemien die zweithaeufigsten malignen Erkrankungen bei Kindern. Waehrend bei Kleinkindern und Adoleszenten supratentorielle Hirntumoren ueberwiegen, ist bei Patienten zwischen 2 und 12 Jahren haeufiger die hintere Schaedelgrube Ursprungsort dieser Malignome. Daraus geht hervor, dass gewisse Tumortypen eine gewisse Alterspraedilektion aufweisen, was neben der radiologischen Morphologie der Raumforderung fuer differenzialdiagnostische Ueberlegungen ueberaus hilfreich sein kann. Das Medulloblastom ist das haeufigste ZNS-Malignom des Kindesalters und repraesentiert zusammen mit zerebellaeren Astrozytomen auch den haeufigsten Tumortyp der hinteren Schaedelgrube. Supratentoriell stehen die Astrozytome ganz im Vordergrund. In dieser Arbeit werden einige typische kindliche infra- und supratentorielle Hirntumoren diskutiert und ihre neuroradiologischen Merkmale dargestellt. (orig.)

    Carcinoid tumors of the midgut arise from the distal duodenum, jejunum, ileum, appendix, ascending and right transverse colon. The appendix and terminal ileum are the most common location. The majority of carcinoid tumors originate from neuroendocrine cells along the gastrointestinal tract, but they are also found in the lung, ovary, and biliary tracts. We report the first case of elective laparoscopic cholecystectomy in which we found a suspicious lesion at the tip of the appendix and proceeded to perform a laparoscopic appendectomy. The lesion revealed a carcinoid tumor of the appendix. PMID:10323177

    There are four types of gastric carcinoid tumors, classified according to their histology and malignant potential. Only a few cases of carcinoid tumors in patients infected with Helicobacter pylori (H. pylori ) have been reported so far. We report a patient infected with H. pylori presenting with a small solitary gastric carcinoid tumor with very low proliferative rate and normal gastrin levels. The tumor was endoscopically removed and the patient received an eradication therapy against H. pylori . No signs of metastatic disease have been found so far during more than 3 year of follow-up. Infection with H. pylori may cause chronic gastritis with normal or elevated gastrin levels, leading to the development of gastric carcinoids by mechanisms unrelated to gastrin. Enterochromaffin-like cell tumors related to a chronic H. pylori infection may be considered as a distinct type of gastric carcinoid tumors.

    2011-01-01

    Carcinoid tumors are the most common neuroendocrine tumors. Gastric carcinoids represent 2% of all carcinoids and 1% of all gastric masses. Due to the widespread use of Esophagogastroduodenoscopy for evaluating a variety of upper gastrointestinal symptoms, the detection of early gastric carcinoids has increased. We highlight an alternative management of a young patient with recurrent type 1 gastric carcinoids with greater than 5 lesions, as well as lesions intermittently greater than 1 cm. Gastric carcinoids have a variable presentation and clinical course that is highly dependent on type. Type 1 gastric carcinoids are usually indolent and have a metastasis rate of less than 2%, even with tumors larger than 2 cm. There are a number of experts as well as organizations that recommend endoscopic resection for all type 1 gastric carcinoid lesions less than 1 cm, with a follow-up every 6-12 mo. They also recommend antrectomy for type 1 gastric carcinoids with greater than 5 lesions, lesions 1 cm or greater, or refractory anemia. However, the American Society of Gastrointestinal Endoscopy guidelines state that type 1 gastric carcinoid surveillance is controversial based on the evidence and could not make an evidence-based position statement on the best treatment modality. Our report illustrates a rare cause of iron deficiency anemia in a young male (without any medical history) due to multiple recurrent gastric carcinoid type 1 lesions in the setting of atrophic gastritis causing hypergastrinemia, and in the absence of a vitamin B12 deficiency. Gastric carcinoid type 1 can present in young males without an autoimmune history, despite the known predilection for women aged 50 to 70 years. Type 1 gastric carcinoids can be managed by endoscopic resection in patients with greater than 5 lesions, even with lesions larger than 1 cm. This course of treatment enabled the avoidance of early antrectomy in our patient, who expressed a preference against more invasive measures at his

    @@ Introduction Neuroendocrine tumor covers a wide range of neoplasms that originate in the neuroendocrine cells which spread throughout the body.Carcinoid tumor, and neuroendocrine tumor are low-grade malignant tumors, their growth is slow, and mainly in the gastrointestinal epithelium. Esophageal adenocarcinoma tumor is a big problem in esophageal cancer. Combined esophageal adenocarcinoma and carcinoid tumor both as primary tumors is very rare[1]. Neuroendocrine tumors of the esophagus are derived from the diffuse neuroendocrine system in the gastrointestinal tract. Neuroendocrine tumors in the esophagus can be distinguished from other mesenchymal tumors by immunostaining for synaptophysin and chromogranin-A. Both carcinoid of the esophagus and adenocarcinoma of the esophagus are malignant tumors and considered to have a specifi c molecular pathogenesis. This paper presents a rare case diagnosed as carcinoid of the esophagus concomitant with an adenocarcinoma of the esophagus, a review of the literature is also presented here.

    Endoscopic ultrasonography with fine needle infusion (EUS-FNI) of alcohol is the most reported method for EUS-guided tumor ablation. Several studies have reported successful EUS-guided ablation of pancreatic neuroendocrine tumors. However, these tumors have been relatively small (tumor with a large porta hepatis mass was referred to our clinic for EUS-guided ethanol ablation. After two separate EUS-FNI ablations, there was a 36 % reduction in tumor size (9.0 × 11.4 cm to 6.7 × 9.8 cm) with associated tumor lysis syndrome. Chromogranin A levels decreased from 460 to 132 ng/mL. The patient reported complete resolution of abdominal pain within 2 weeks, but only mild improvement in flushing and diarrhea. In conclusion, large metastatic neuroendocrine tumors can be successfully treated with EUS-guided ethanol ablation. Evidence-based guidelines are needed with regard to the appropriate volume of ethanol injected in EUS-guided ablation to promote the efficacy and safety of this emerging procedure. PMID:26135103

    We encountered a 6S-year-old man with a carcinoid tumor of the minor duodenal papilla. Since he had liver cirrhosis and completely refused surgery, we performed an endoscopic snare papillectomy. The papillectomy was performed successfully without procedure-related complication. The specimens revealed a carcinoid tumor showing that the margin of the tumor was positive. One week later, upper GI endoscopy was performed and the biopsy specimens obtained from base of ulcer showed no neoplastic cells. We performed a duodenoscopy and CT 3, 6 and 18 mo later, and there was no macroscopic or microscopic evidence of tumor recurrence after more than 4 years.

    Inflammatory myofibroblastic tumor is a rare benign neoplasm and most commonly involves the lung but occurs in extrapulmonary locations. To present imaging findings in inflammatory myofibroblastic tumors in children based on a single-centre experience. We retrospectively reviewed CT and MRI findings of children diagnosed with inflammatory myofibroblastic tumor in a single institution. We identified 15 children (range: 1-17 years) with inflammatory myofibroblastic tumor. The tumor was localized to the lung (n = 5), mediastinum (n = 3), trachea (n = 1), bronchus (n = 1), abdomen (n = 2) and orbit (n = 3). All the extraorbital tumors were solid masses with homogeneous or heterogeneous enhancement. Four lung tumors and one posterior mediastinal tumor contained calcification. Local recurrence following surgical removal occurred in two children with invasion of the esophagus and of the left atrium in one. Localized masses were seen in all children with orbital tumour. Two of these had episcleritis and perineuritis; one had episcleritis, tendonitis, perineuritis, myositis and dacryoadenitis. The locations and imaging features of inflammatory myofibroblastic tumors are variable. (orig.)

  10. Childhood kidney tumors - the relevance of imaging

    International Nuclear Information System (INIS)

    Kidney tumors represent 6.2% of malignant tumors in children. History, clinical course and radiological findings are necessary elements in the differential diagnosis of the different renal tumors. In the case of nephroblastoma, chemotherapy is based solely on the radiological diagnosis without prior histology. In therapy-optimizing studies of the Society of Pediatric Oncology and Hematology, preoperative chemotherapy is performed. Therapy monitoring is performed in the course of and after preoperative chemotherapy to verify tumor response. Radiological staging plays a significant role in deciding on further treatment and in operative planning. Three-dimensional visualization of the abdominal situs can assist preoperative planning. In summary, diagnostic imaging in renal tumors in children plays a role in differential diagnosis, staging, monitoring of therapy, and surgical planning. (orig.)

    Full Text Available Teratomas are neoplasms comprising of tissues derived from more than one germ layer. Most common sites are gonads, sacrococcygeal, mediastinal, retroperitoneal, and pineal region. Here, we report a case of 2 -year-old previously healthy female toddlerwho presented with fever and right upper quadrant abdominal pain. Magnetic resonance imaging (MRI of the abdomen revealed a right suprarenal nonenhancing cystic mass. Focal calcification was seen in the inferomedial aspect of the cyst. Complete surgical resection of the right adrenal gland was done. The patient had an uneventful postoperative course and was free of recurrence at 8 months follow-up. Primary retroperitoneal teratomas of the adrenal gland are very uncommon (4% of all primary teratomas and can mimic a primary adrenal tumor, hence should be included in the differential diagnosis of adrenal masses.

    Adult survivors of childhood brain tumors experience multiple, significant, lifelong deficits as a consequence of their malignancy and therapy. Current survivorship literature documents the substantial impact such impairments have on survivors' physical health and quality of life. Psychosocial reports detail educational, cognitive, and emotional limitations characterizing survivors as especially fragile, often incompetent, and unreliable in evaluating their circumstances. Anecdotal data suggest some survivors report life experiences similar to those of healthy controls. The aim of our investigation was to determine whether life satisfaction in adult survivors of childhood brain tumors differs from that of healthy controls and to identify potential predictors of life satisfaction in survivors. This cross-sectional study compared 78 brain tumor survivors with population-based matched controls. Chi-square tests, t tests, and linear regression models were used to investigate patterns of life satisfaction and identify potential correlates. Results indicated that life satisfaction of adult survivors of childhood brain tumors was similar to that of healthy controls. Survivors' general health expectations emerged as the primary correlate of life satisfaction. Understanding life satisfaction as an important variable will optimize the design of strategies to enhance participation in follow-up care, reduce suffering, and optimize quality of life in this vulnerable population.

    2015-01-01

    Full Text Available Lung carcinoids tumors are uncommon tumors that start in the lung. They tend to grow slower than other types of lung cancers. Carcinoids tumors start from cells of the diffuse neuroendocrine system. It is widely recognized that cytology is superior to small biopsy in diagnosing small cell lung carcinoma since the crush artefacts limiting small biopsy interpretation is minimized in cytology. Similarly, carcinoids can be accurately diagnosed in cytology and small biopsy specimen. A correct preoperative cytological diagnosis helps in planning early and optimal surgery. We received the fine-needle aspiration cytology sample of bronchial mass of 46-year-old patient presenting with cough and hemoptysis for 2 months. Diagnosis of carcinoid tumor was given on cytology that was confirmed on histopathology and immunohistochemistry.

    1984-03-01

    The CT findings in 10 patients with carcinoid tumors of the lung are reported. The tumors were located in the hilar region, in the perihilar region and in the periphery of the lung. Dystelectasis and atelectasis of the lung with poststenotic inflammation were found in 4 patients. Infiltrating tumor growth with lymph node metastases were detected only once. This tumor was not able to be differentiated from other malignant space occupying lesions. There were no reliable CT criteria for bronchial carcinoids. Compared to conventional radiography the CT examination has the following advantages: better demonstration of size and location of the tumor, and the exlusion of infiltrating tumor growth, enlarged lymph nodes and calcified lung nodules.

    Full Text Available Introduction. Teratomas are tumors derived from pluripotent germ cells, and they appear most frequently in ovaries. Strumal carcinoid belongs to the group of monodermal teratomas. Strumal carcinoid is characterized by the presence of carcinoid tumor, intermingled with thyroid tissue. Case report. A 52-year-old postmenopausal woman was referred to the Department of Gynecology and Obstetrics, Clinical Center of Vojvodina, Novi Sad with complex right adnexal mass for surgery. Laparotomy revealed tumor arising from the right ovary, of firm consistency and intact capsule. On gross examination, yellowish brown tumor was 26 x 17 x 10 cm, with vague nodularity. The cut sections revealed predominantly solid mass with two cystic areas, and one of the cysts showed a tuft of hair. On histopathological examination, the cystic spaces were lined with skin and mucinous epithelium. The solid areas showed a population of monomorphic cells with eosinophilic cytoplasm and nuclei with ”salt and pepper” chromatin, arranged in acinar and trabecular patterns, respectively. In addition, focally follicular structures with central eosinophilic colloid-like material were seen. Based on the presence of these two components, a diagnosis of Strumal Carcinoid was made and confirmed on immunohistochemistry. The tumor cells were diffusely immunopositive for synaptophysin, chromogranin, and the follicles including the central colloid were immunopositive for thyroglobulin and Thyroid transcription factor-1. Neither proliferative or mitotic activity nor capsular or angiolymphatic invasion were noticed. At 3 year follow up the patient was disease free. Conclusion. In order to diagnose this rare tumor a team, consisting of a pathologist, surgeon and radiologist, is needed. Diagnosis of strumal carcinoid has to be confirmed on immunohistochemistry.

    Carcinoid tumors generally appear as yellow/gray or tan submucosal nodules. We experienced a case of pedunculated rectal carcinoid showing a mushroom-like appearance. The case was a forty years old woman who was admitted to our hospital due to rectal bleeding. Colonoscopy revealed a pedunculated polyp presenting a mushroom-shaped appearance measuring 13 mm in diameter in the rectum.The histological diagnosis of specimens obtained by biopsy was adenocarcinoma and transanal ultrasonography revealed the tumor localization within the submucosal layer in the rectum. Endoscopic mucosal resection (EMR) was performed.Histopathological examination established the diagnosis of carcinoid tumor in the rectum. Frequencies of the pedunculated type in rectal carcinoids were reported to be 2.4 % to 7.1% in the literature. Because of its rarity,pedunculated configuration may confuse the endoscopic diagnosis of carcinoids. Treatment for carcinoids of 1 to 1.5 cm in size remains controversial. Although such tumors are technically respectable by EMR, careful attention must be paid in dealing with these tumors because there may be unexpected behaviors of the tumors.

    Full Text Available Monodermal teratomas of the ovary can take the form of carcinoid tumors of which there are several types, mucinous carcinoid being the least common. Very few cases of primary mucinous carcinoid of the ovary have been reported in the literature and the behavior of these tumors over the long term is unclear. We describe a case of primary mucinous carcinoid of the ovary in a 39-year-old woman treated with unilateral salpingo-oophorectomy, where a metastasis occurred in the contralateral ovary ten years later. This case demonstrates that mucinous carcinoid of the ovary can metastasize even after a long interval, and careful follow-up of patients, particularly those treated conservatively, is appropriate.

    One hundred forty-three patients who received radiation therapy for childhood tumors, and survived to the age of skeletal maturity, were studied by retrospective review of oncology records and roentgenograms. Diagnoses for the patients were the following: Hodgkin's lymphoma (44), Wilms's tumor (30), acute lymphocytic leukemia (26), non-Hodgkin's lymphoma (18), Ewing's sarcoma (nine), rhabdomyosarcoma (six), neuroblastoma (six), and others (four). Age at the follow-up examination averaged 18 years (range, 14-28 years). Average length of follow-up study was 9.9 years (range, two to 18 years). Asymmetry of the chest and ribs was seen in 51 (36%) of these children. Fifty (35%) had scoliosis; 14 had kyphosis. In two children, the scoliosis was treated with a brace, while one developed significant kyphosing scoliosis after laminectomy and had spinal fusion. Twenty-three (16%) patients complained of significant pain at the radiation sites. Twelve of the patients developed leg-length inequality; eight of those were symptomatic. Three patients developed second primary tumors. Currently, the incidence of significant skeletal sequelae is lower and the manifestations are less severe than reported in the years from 1940 to 1970. The reduction in skeletal complications may be attributed to shielding of growth centers, symmetric field selection, decreased total radiation doses, and sequence changes in chemotherapy.

    Full Text Available Abstract Background Goblet cell carcinoid (GCC of the appendix is a rare neoplasm that share histological features of both adenocarcinoma and carcinoid tumor. While its malignant potential remains unclear, GCC's are more aggressive than conventional carcinoid. The clinical presentations of this neoplasm are also varied. This review summarizes the published literature on GCC of the appendix. The focus is on its diagnosis, histopathological aspects, clinical manifestations, and management. Methods Published studies in the English language between 1966 to 2004 were identified through Medline keyword search utilizing terms "goblet cell carcinoid," "adenocarcinoid", "mucinous carcinoid" and "crypt cell carcinoma" of the appendix. Results Based on the review of 57 published papers encompassing nearly 600 diagnosed patients, the mean age of presentation for GCC of the appendix was 58.89 years with equal representation in both males and females. Accurate diagnosis of this neoplasm requires astute observations within an acutely inflamed appendix as this neoplasm has a prominent pattern of submucosal growth and usually lacks the formation of a well-defined tumor mass. The mesoappendix was involved in 21.64% followed by perineural involvement in 2.06%. The most common clinical presentations in order of frequency were acute appendicitis in 22.5%; asymptomatic in 5.4%; non-localized abdominal pain in 5.15% and an appendicular mass in 3.09%. The most common surgical treatment of choice was appendectomy with right hemicolectomy in 34.70% followed by simple appendectomy in 24.57%. Concomitant distant metastasis at diagnosis was present in 11.16% of patients with the ovaries being the most common site in 3.60% followed by disseminated abdominal carcinomatosis in 1.03%. Local lymph node involvement was seen in 8.76% of patients at the time of diagnosis. The reported 5-year survival ranges from 60 % to 84%. GCC's of the appendix remains a neoplasm of unpredictable

    2006-01-01

    Carcinoids involving the ampulla of Vater are rare lesions that may produce painless jaundice. The published data indicate that these tumors, in contrast to their midgut counterparts, metastasize in approximately half of cases irrespective of primary tumor size. Therefore,radical excision in the form of pancreaticoduodenectomy is recommended regardless of tumor size. As with other gastrointestinal carcinoid tumors, biological treatment with octreotide analogues can be applied to symptomatic patients. Tumor-targeted radioactive therapy is a newly emerging treatment option. We here report case of a carcinoid tumor of the ampulla of Vater presenting as painless jaundice in a 65-year old man and review the relevant literature, giving special attention to the morphologic features, clinical characteristics, and treatment modalities associated with this disease process.

    We report a case of multiple duodenal, pancreatic, and gastric carcinoids. A 67-year old woman was admitted to our hospital for treatment of a duodenal carcinoid.Laboratory tests revealed that the patient was associated with macrocytic anemia and hypergastrinemia, and type A gastritis was shown by gastrofiberscopy.During surgery, another tumor was incidentally found in the head of the pancreas. The tumors in the duodenum and pancreas were completely excised by pancreatoduodenectomy and immunohistologically diagnosed as gastrin-and serotonin-producing carcinoids,respectively. Pathological examination revealed that in addition to the grossly found carcinoids, there were subclinical carcinoids, one of which was an endocrine cell micronest, located in the stomach and duodenum.The tumors in the duodenum, pancreas, and stomach showed different characteristics from one another morphologically and immunochemically. Although no definitive evidence has been obtained, some sort of genetic anomaly may have been involved in this case,and hypergastrinemia due to duodenal gastrinoma may induce multiple gastric carcinoids.

    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

    We describe 2 cases of endobronchial pulmonary carcinoid tumor with superimposed Aspergillus colonization. The Aspergillus hyphae were associated with fibrin, ulcer debris, and granulomatous inflammation in part masking the carcinoid tumor. Presence of necrotic debris made diagnosis on biopsy difficult, and atypical carcinoid could not be ruled out. The association of carcinoid tumor with aspergillosis is rare and has been reported in 4 other cases thus far. A review of the literature reveals at least 35 cases of lung carcinoma with coexisting Aspergillus upon presentation. Most of these carcinomas are either cavitary squamous cell or adenocarcinomas harboring an aspergilloma. The other carcinomas are associated with bronchial obstruction as in carcinoids or are a minor component of a preexisting cavity raising the possibility of "scar carcinoma." As in aspergillomas not associated with carcinoma, upper lobe involvement predominates. Diagnosis can be challenging with delayed discovery of underlying neoplasm leading to suboptimal treatment.

    The somatostatin analogue octreotide may be used in the diagnosis of carcinoid and other neuroendocrine tumours. Radionuclide scanning following intravenous injection of 111Indium-labelled octreotide (111In-DTPA-pentetreotide) provides a sensitive, non-invasive method of localising somatostatin-positive tumours. The technique may also be used to identify patients who may respond to 'cold' octreotide therapy and to monitor therapeutic efficacy.

    Carcinoid tumors are neuroendocrine tumors with a very unpredictable clinical behavior. In the setting of hepatic metastases, the tumor's release of bioactive substances into the systemic circulation results in carcinoid syndrome: a constellation of symptoms among which cutaneous flushing, gastrointestinal hypermotility, and cardiac involvement are the most prominent. Cardiac manifestations, also known as carcinoid heart disease, are secondary to a severe fibrotic reaction which frequently involves the right-sided valves and may extend towards the subvalvular apparatus leading to valve thickening and retraction. Left-sided involvement is rare and mostly observed in the presence of an interatrial shunt, endobronchial tumor localization, and high tumor activity. Echocardiographic techniques often reveal noncoaptation of the valves, which are fixed in a semiopen position. In patients with advanced lesions and severe valvular dysfunction, surgery is currently the only definitive treatment to potentially improve quality of life and provide survival benefit. Although cardiac surgery has been traditionally reserved for those patients with symptomatic right ventricular failure, a significant trend towards improved surgical outcomes has triggered a more liberal referral for valve replacement. Carcinoid heart disease poses two distinct challenges for the anesthesiologist: carcinoid crisis and low cardiac output syndrome secondary to right ventricular failure. Carcinoid crisis, characterized by flushing, hypotension, and bronchospasm, may be precipitated by catecholamines and histamine releasing drugs used routinely in patients undergoing valve surgery. Although a broader utilization of octreotide have significantly simplified the anesthetic and perioperative management of these patients, a very balanced anesthetic technique is required to identify and manage low cardiac output syndrome.

  16. Partitioning of bronchopulmonary carcinoids in two different prognostic categories by Ki-67 score

    Full Text Available Introduction: Histological distinction between typical and atypical bronchopulmonary carcinoids is based on mitotic activity and necrosis. Regardless of these two parameters, outcome after surgery is often unpredictable. In this study the prognostic value of different clinico-pathological factors was retrospectively analyzed in a large series of patients with bronchopulmonary carcinoid.Patients & Methods: The long-term postsurgical outcome of 106 radically treated patients affected by bronchopulmonary carcinoid from 2 Italian centers was correlated with tumor characteristics assessed by combining conventional histology with a panel of immunohistochemical markers of neuroendocrine differentiation (chromogranin-A, NSE and proliferation activity (Ki-67 score. Results: Carcinoids were assessed as typical (TC=75; 70.8% and atypical (AC=31; 29.2%. Mean follow-up was 8.3 years (range: 0-20; median: 8.0. All cases expressed neuroendocrine markers. At univariate analysis, tumor recurrence [14/75 TC (18.7%, 15/31 AC (48.4%] correlated with carcinoid histotype (P = 0.003, tumor size (P = 0.012, mitotic index (P = 0.044, Ki-67 score (P < 0.0001, and synchronous node metastasis (P = 0.037. Of these, Cox multivariate analysis confirmed only Ki-67 score as independent predictor of disease recurrence (P = 0.009. The best cut-off for Ki-67 score (calculated by ROC curves discriminating recurrent versus non recurrent disease was 4% (sensitivity 79.3%; specificity 83.8%; area under the curve 0.85. By stratifying patients according to this cut-off, a significantly different disease-free survival was found (log-rank test P < 0.0001.Conclusions: Ki-67 score accurately separates bronchopulmonary carcinoids in two well-distinct histo-prognostic categories. Ki-67 score predicts the patient’s outcome better than mitotic count, histotype and tumor stage and it is therefore helpful in establishing the appropriate follow-up.

    Full Text Available Ovarian tumors of childhood and adolescence constitute the most frequent and special group of gynaecologic tumors due to clinical and histopathological peculiarities and age specific therapeutic implications related to physically, hormonally and immunologically immature host. Pathologic features of ovarian tumors of children and adolescents diagnosed in our department in ten-year period, constitute the perspective of this report. Macroscopical, microscopical, immunohistochemical, and cytopathological features of ovarian tumors under 21-years-of age, and diagnosed in 1997-2006 are re-evaluated.Fourty-two cases (9.7% belong to the young patients among 391 primary ovarian tumors diagnosed in tenyears. Germ-cell tumors were the most frequent (54.8% while epithelial tumors were 38.1% and sexcord- stromal tumors was 7.1%. Malignancy rate was 28.6% among all subtypes while epithelial malignancy were 4.8%. Malignancy under 16 years was 31.3% while it was 26.9% in adolescence. Epithelial tumors in childhood was 18.8% while it was 50% over 16 years; the difference was significant (p=0.043. In our series, 60.9% of germ cell tumors were mature cystic teratomas. Malignancy rate within this group was 39.1%. There were four pure dysgerminomas, three mixed germ cell tumors and two immature teratomas within the malignant germ cell tumors. The mean tumor diameter was 92.1 mm. in benign tumors while it was 172.9 mm. in malignant tumors, and the difference was significant (p=0.001. Most of the solid tumors were malignant (p=0.002.As the malignancy potential among the young was considerably high, a detailed clinical and pathological evaluation is mandatory for abdominopelvic masses.

    Full Text Available The aim of this paper is to determine the influence of Ki-67 proliferation index on somatostatin receptor scintigraphy (SSRS with Tc-99m-EDDA-HYNIC-TOC (Tc-99m-Tektrotyd somatostatin analogue in patients with carcinoid tumors. Sixty-one patients (31 female, 30 male; age range: 33-76 years were examined: 13 patients highly suspected of having a carcinoid, and 48 patients who had undergone the surgical removal of the tumor. Whole body SSRS at 4 h postinjection, spot scintigrams and SPECT of the selected regions were obtained for all patients. Tc-99m-Tektrotyd scintigraphy was classified as true positive in 26 out of 30 and true negative in 24 out of 28 patients. The sensitivity of Tc-99mTc-Tektrotyd scintigraphy was found to be as high as 94.74% in the group of patients with low mitotic index Ki67 (20%. The likelihood of Tc-99m-Tektrotyd scan being positive when a carcinoid is present was found to be inversely proportional to the value of Ki67 proliferation index. The results showed that Tc-99m-Tektrotyd SSRS is a sensitive method for diagnosing and staging patients with well-differentiated carcinoid tumors. However, in poorly differentiated tumors with high Ki67 proliferation index, additional analyses are necessary for precise staging.

    Cushing's syndrome occurred in 1-5% of cases of bronchial carcinoids. In this paper we describe a case of typical bronchial carcinoid in a nonsmoker young male with clinical manifestations mimicking a Cushing's syndrome. The patient performed chest radiograph and computed tomography. Fiberoptic bronchoscopy revealed the presence of an endobronchial mass occluding the bronchus intermedius. A rigid bronchoscopy was necessary for the conclusive diagnosis and for partial resection of the intraluminal tumor. Despite of the presence of Cushingoid features, the normal blood levels of ACTH and cortisol excluded the coexistence of a Cushing's syndrome.

    Hedinger syndrome refers to carcinoid valvular heart disease. The disease is believed to be triggered by vasoactive substances that result in valvular fibrosis. It classically occurs in patients with metastatic carcinoid and preferentially involves the right sided cardiac valves. Affected valves become thickened and retracted, exhibiting regurgitation and sometimes, stenosis. Echocardiography is recommended in patients with carcinoid syndrome and a follow up study is advisable in those who develop a murmur or other symptoms or signs of valvular heart disease. For appropriately selected patients, valve replacement surgery appears to improve outcomes.

    Brain tumors are the second most common childhood malignancy. Between 1975 and 1985, 462 newly diagnosed patients were treated at the Children's Hospital of Philadelphia; 207 (45%) tumors arose in the posterior fossa and 255 (55%) appeared supratentorially. A wide variety of histological subtypes were seen, each requiring tumor-specific treatment approaches. These included primitive neuroectodermal tumor (n = 86, 19%), astrocytoma (n = 135, 30%), brainstem glioma (n = 47, 10%), anaplastic astrocytoma (n = 32, 7%), and ependymoma (n = 30, 6%). Because of advances in diagnostic abilities, surgery, radiotherapy, and chemotherapy, between 60% and 70% of these patients are alive today. Diagnostic tools such as computed tomography and magnetic resonance imaging allow for better perioperative management and follow-up, while the operating microscope, CO/sub 2/ laser, cavitron ultrasonic aspirator and neurosurgical microinstrumentation allow for more extensive and safer surgery. Disease specific treatment protocols, utilizing radiotherapy and adjuvant chemotherapy, have made survival common in tumors such as medulloblastoma. As survival rates increase, cognitive, endocrinologic and psychologic sequelae become increasingly important. The optimal management of children with brain tumors demands a multidisciplinary approach, best facilitated by a neuro-oncology team composed of multiple subspecialists. This article addresses incidence, classification and histology, clinical presentation, diagnosis, pre-, intra- and postoperative management, long-term effects and the team approach in posterior fossa tumors in childhood. Management of specific tumor types is included as well. 57 references.

    Refior, H.J.; Stuerz, H.

    1982-09-01

    Skeletal changes leading to a suspicion of the presence of a tumour frequently occur in childhood with the roentgenological manifestation of a cyst. X-ray morphology can differ depending upon the localisation and the course. In childhood, however such findings are mainly classified as tumour-like bone lesions. This group comprises, inter alia, the juvenile bone cyst, the aneurysmatic bone cyst and fibrous dysplasia. However, it is necessary to exclude by differential diagnosis - even though the main age of manifestation is after completion of growth - genuine bone tumours with cystic phenomena, such as the giant cell tumour, chondroma or chondroblastoma. Verification of the diagnosis can be effected via radiologic-diagnostic methods such as tomography and angiography as well as computerized tomography. The use of scintigraphy of the skeleton can likewise be indicated. Numerous laboratory parameters can be used in individual cases to exclude certain diagnoses. Taking these aspects into consideration, the article reviews differential diagnosis of the most frequent skeletal affections in childhood. Great emphasis is given to the ranking and importance of the individual diagnostic methods.

However, recent epidemiologic studies on the cancer risks among children who received repeated CT scans, radiotherapies and A-bomb have revealed that low-to-moderate dose of ionizing radiation is effective to induce brain tumors. Ionizing radiation is more strongly associated with risk for meningiomas and schwannomas compared to gliomas. While risk of meningiomas is independent of age at the time of exposure, that of gliomas is profoundly high after neonatal and infantile exposures. Inherited susceptibility to brain tumors is suggested by family history or cancer prone syndromes. People with certain gene mutations such as RB, NF1 or PTCH1 are associated with enhanced cancer risk after radiotherapies. Genetic polymorphism of cancer-related genes on brain tumor risk deserves further investigation. (author)

  16. Specific aspects of radiotherapy of malignant tumors in childhood

    International Nuclear Information System (INIS)

    Based on the experience with radiotherapy of malignant tumors in 1839 children treated at the Oncological Clinic in Prague from 1946 to 1985, the conclusion is arrived at that some specific aspects of radiotherapy of tumors in children, such as kinetics and biological features are so important that it can be considered a special sub-discipline of clinical radiotherapy. An opinion is expressed about the application of irradiation in non-malignant affections in children. (author). 2 figs., 4 tabs., 25 refs

  17. An ileal endometrioma: of carcinoids and cadherin.

    2007-02-01

    A 38-year-old woman with history of prior adrenalectomy for Cushing's syndrome presented with intermittent right lower quadrant (RLQ) abdominal pain, nausea, bloating, and non-bloody diarrhea for 2 months. Symptoms were not related to her menstrual periods. Examination revealed only an ill-defined mass in the RLQ. Investigations for infectious causes, inflammatory bowel disease, and carcinoid tumor were negative. Computed tomography (CT) demonstrated a terminal ileal mass with mesenteric stranding and dilatation of the proximal bowel. At laparotomy, a fibrotic, terminal ileal mass with matted adhesions involving the mesentery and retroperitoneum was resected. Histopathological examination identified multiple foci of endometriosis extending from the serosal surface into the mucosa of the terminal ileum. Immunostaining revealed E- and P-cadherin, but not N-cadherin immuno-positivity. Mucosal involvement without cyclical menstrual symptoms and intestinal obstruction is an unusual presentation of intestinal endometriosis. Although the mechanism of endometriosis is not clear, the role of cell adhesion molecules such as cadherins has received attention. Increased expression of E- and P-cadherin and decreased N-cadherin expression in our patient demonstrates differential expression of these cadherins in endometriotic tissue. Future studies may investigate patterns of differential expression of these cadherins in a series of cases to elucidate the mechanisms of migration of endometriotic tissue. PMID:17390177

  18. Radiotherapy in osseous metastasizing carcinoid

    International Nuclear Information System (INIS)

    In an 51-year old patient with a disseminately metastasizing bronchus carcinoid, percutaneous radiotherapy was employed as a palliative measure against most severe pain in the region of bone metastases. In all irradiated regions (entire vertebral column and both shoulders) good pain relief was achieved in 2 weeks, lasting until the end of the follow-up period (18 months after irradiation), by application of 30 Gy photon radiation. Correlated with the subjective pain relief was a reduction of the required quantity of analgesics, a reduction of the greatly increased activity of alkaline phosphatase in the serum, and roentgenological sclerosing of the metastatic bone lesions. This case report is intended to point to the possibility of employing radiotherapy in similar cases where medication has finally proved futile, since the rare reports in literature are mostly negative.

    2012-08-01

    Full Text Available In the duodenum, mixed exocrine-endocrine tumors exhibiting both neuroendocrine and glandular differentiations [cf. appendiceal goblet cell carcinoids (GCCs] are rare. We present a Japanese case with a duodenal GCC that was found during pathologic examination of a gastrectomy specimen removed for gastric mucosal cancer. The tumor was widely distributed within both the first portion of the duodenum and the gastric antrum, although mucosal involvement was observed only in the duodenum. The tumor cells formed solid nests, trabeculae, or tubules, and some displayed a goblet cell appearance. They were immunoreactive against antibodies for both serotonin and somatostatin, and showed an argentaffin reaction (similar to a “midgut” enterochromaffin cell carcinoid. Ultra-structurally, the tumor cells had an amphicrine nature. Physicians encounter GCC in the duodenum only rarely, and its discovery may be incidental. Its diagnosis will be challenging and will require careful clinical and pathologic examinations.

    The authors analyze the magnetic resonance imaging (MRI) as the imaging modality of choice for evaluation of patients with bone tumors or soft tissue tumors. The advent of such a sensitive imaging modality is fortuitous and coincides with a recent change in the therapeutic approach to primary bone tumors. MRI is extremely valuable in monitoring the tumor response to the initial chemotherapy and is accurate defining the margins of tumor, facilitating planning of limb salvage surgical procedures.

    Ampullary carcinoid is a rare tumor that can present with gastrointestinal bleeding, obstructive jaundice or pancreatitis. Some of these tumors are associated with Von Recklinghausen disease. The usual surgical options are a biliary-enteric anastomosis, Whipple procedure or rarely a local resection. The mean survival dges not appear to be much different after a pancreaticoduodenectomy versus local surgical excision.We report a very rare case of a non-metastatic ampullary carcinoid causing upper gastrointestinal bleeding, which was managed by endoscopic ampullectomy.

    Significant advances have been made over the past 25 years in our understanding of the most common adult solid tumors such as breast, colon, lung and prostate cancer. Much less is known about childhood solid tumors because they are rare and because they originate in developing organs during fetal development, childhood and adolescence. It can be very difficult to study the cellular origins of pediatric solid tumors in developing organs characterized by rapid proliferative expansion, growth factor signaling, developmental angiogenesis, programmed cell death, tissue reorganization and cell migration. Not only has the etiology of pediatric cancer remained elusive because of their developmental origins, but it also makes it more difficult to treat. Molecular targeted therapeutics that alter developmental pathway signaling may have devastating effects on normal organ development. Therefore, basic research focused on the mechanisms of development provides an essential foundation for pediatric solid tumor translational research. In this article, we describe new resources available for the developmental biology and oncology research communities. In a companion paper, we present the detailed characterization of an orthotopic xenograft of a pediatric solid tumor derived from sympathoadrenal lineage during development. PMID:26068307

  6. Pituitary tumors in childhood: update of diagnosis, treatment and molecular genetics.

    2008-04-01

    Pituitary tumors are rare in childhood and adolescence, with a reported prevalence of up to one per 1 million children. Only 2-6% of surgically treated pituitary tumors occur in children. Although pituitary tumors in children are almost never malignant and hormonal secretion is rare, these tumors may result in significant morbidity. Tumors within the pituitary fossa are mainly of two types: craniopharyngiomas and adenomas. Craniopharyngiomas cause symptoms by compressing normal pituitary, causing hormonal deficiencies and producing mass effects on surrounding tissues and the brain; adenomas produce a variety of hormonal conditions such as hyperprolactinemia, Cushing disease and acromegaly or gigantism. Little is known about the genetic causes of sporadic lesions, which comprise the majority of pituitary tumors, but in children, more frequently than in adults, pituitary tumors may be a manifestation of genetic conditions such as multiple endocrine neoplasia type 1, Carney complex, familial isolated pituitary adenoma and McCune-Albright syndrome. The study of pituitary tumorigenesis in the context of these genetic syndromes has advanced our knowledge of the molecular basis of pituitary tumors and may lead to new therapeutic developments.

    Full Text Available Objective: In this study, we aimed to give a documentation of 37 cases of childhood fibroblastic/myofibroblastic tumors retrieved from the archives of 6 reference centers in Ankara along with a comprehensive review on the subject.Material and Method: A retrospective archive search was carried out for the period between 2006-2010 in 6 reference centers in Ankara covering patients with ages ranging between 0-18 years. All the tumors categorized under fibroblastic and myofibroblastic group according to World Health Organization criteria were collected.Results: The study comprised 407 soft tissue tumors in total. Fibroblastic/myofibroblastic tumors constituted 9,1 % (37 cases of these tumors. According to histopathology; 16 cases were categorized as fibromatosis, 8 cases as inflammatory myofibroblastic tumor, 6 cases as infantile fibrous hamartoma, 3 cases as nodular fasciitis and 2 cases as infantile myofibroblastic tumor/myofibromatosis and 1 case as cranial fasciitis. The only malignant case was an infantile fibrosarcoma.Conclusion: Infantile fibrosarcoma was lower than reported series and a male predominance was noted. The low incidence of newly described entities as well suggests that these tumors may have been unrecognized.

    Full Text Available PURPOSE: Metastatic neuroendocrine tumors secrete serotonin and other vasoactive substances that are responsible for carcinoid syndrome and carcinoid heart disease. We sought to evaluate the discriminatory utility of diagnostic biomarkers in determining the presence and severity of carcinoid heart disease in patients with metastatic neuroendocrine tumors. PATIENTS AND METHODS: A cross-sectional study of patients with neuroendocrine tumors with documented liver metastases and/or carcinoid syndrome between April 2009-October 2012 in 5 tertiary referral centers. Serum was analyzed for Chromogranin A, Chromogranin B and N-terminal pro Brain Natriuretic Peptide (NT-proBNP. Plasma was analyzed for Neurokinin A and 5-Hydroxyindoleacetic acid (5HIAA. Echocardiography was used to determine the presence and severity of carcinoid heart disease. Non-parametric receiver operating characteristic curves were constructed for biomarkers, and the area under the curve determined. The severity of cardiac involvement was correlated with the concentration of each biomarker. RESULTS: A total of 187 patients were identified of whom 37 (20% had carcinoid heart disease. Significantly higher median values of all biomarkers were found in the patients with cardiac involvement. NT-proBNP and plasma 5HIAA had the highest areas under the curve for the prediction of carcinoid heart disease [NT-proBNP 0.82 (95% confidence interval 0.74-0.90, p<0.0001 and 5HIAA 0.85 (95% confidence interval 0.78-0.92, p<0.0001]. NT-proBNP was moderately correlated (r = 0.48, p<0.001 whereas plasma 5HIAA was only weakly correlated (r = 0.34, p<0.001 with the echocardiographic severity score. CONCLUSION: NT-proBNP and plasma 5HIAA are both sensitive and specific biomarkers for the presence of carcinoid heart disease whereas only NT-proBNP is moderately correlated with disease severity.

  10. Radiological diagnostics of malignant tumors of the musculoskeletal system in childhood and adolescence

    International Nuclear Information System (INIS)

    Rhabdomyosarcoma, osteosarcoma and Ewing's sarcoma are the most common malignant tumors of the musculoskeletal system in childhood and adolescence representing about 10% of newly diagnosed cancers in children and adolescents. In the last two decades the prognosis of patients with such malignancies improved significantly. On the one hand because of the advances in chemotherapy and orthopedic surgery, on the other hand also because of the innovations in radiological diagnostics. The precise pre-therapeutical staging of tumors of the musculoskeletal system provides important prognostic information and has impact on the entire therapy management. During respectively after therapy, imaging is extremely important in the follow-up and in diagnosing a possible recurrent disease. Modern imaging diagnostics of musculoskeletal tumors basically consist of conventional X-ray, of computed tomography (CT) and magnetic resonance imaging (MRI), and of modalities of nuclear medicine such as szintigraphy, positron emission tomography (PET) and PET CT.

    Full Text Available Cushing’s syndrome occurred in 1–5% of cases of bronchial carcinoids. In this paper we describe a case of typical bronchial carcinoid in a nonsmoker young male with clinical manifestations mimicking a Cushing’s syndrome. The patient performed chest radiograph and computed tomography. Fiberoptic bronchoscopy revealed the presence of an endobronchial mass occluding the bronchus intermedius. A rigid bronchoscopy was necessary for the conclusive diagnosis and for partial resection of the intraluminal tumor. Despite of the presence of Cushingoid features, the normal blood levels of ACTH and cortisol excluded the coexistence of a Cushing’s syndrome.

  16. Combination of carbonic anhydrase inhibitor, acetazolamide, and sulforaphane, reduces the viability and growth of bronchial carcinoid cell lines

    International Nuclear Information System (INIS)

    Bronchial carcinoids are pulmonary neuroendocrine cell-derived tumors comprising typical (TC) and atypical (AC) malignant phenotypes. The 5-year survival rate in metastatic carcinoid, despite multiple current therapies, is 14-25%. Hence, we are testing novel therapies that can affect the proliferation and survival of bronchial carcinoids. In vitro studies were used for the dose–response (AlamarBlue) effects of acetazolamide (AZ) and sulforaphane (SFN) on clonogenicity, serotonin-induced growth effect and serotonin content (LC-MS) on H-727 (TC) and H-720 (AC) bronchial carcinoid cell lines and their derived NOD/SCID mice subcutaneous xenografts. Tumor ultra structure was studied by electron microscopy. Invasive fraction of the tumors was determined by matrigel invasion assay. Immunohistochemistry was conducted to study the effect of treatment(s) on proliferation (Ki67, phospho histone-H3) and neuroendocrine phenotype (chromogranin-A, tryptophan hydroxylase). Both compounds significantly reduced cell viability and colony formation in a dose-dependent manner (0–80 μM, 48 hours and 7 days) in H-727 and H-720 cell lines. Treatment of H-727 and H-720 subcutaneous xenografts in NOD/SCID mice with the combination of AZ + SFN for two weeks demonstrated highly significant growth inhibition and reduction of 5-HT content and reduced the invasive capacity of H-727 tumor cells. In terms of the tumor ultra structure, a marked reduction in secretory vesicles correlated with the decrease in 5-HT content. The combination of AZ and SFN was more effective than either single agent. Since the effective doses are well within clinical range and bioavailability, our results suggest a potential new therapeutic strategy for the treatment of bronchial carcinoids

    Full Text Available Background: Childhood cancers represent an important global public health problem. Survival is still dismal in most low income countries. Materials and Methods: A prospective study of childhood cancers diagnosed at AKTH, Kano was undertaken from January 2003 to December 2009 to determine the pattern, socio-economic and geographical features. Results: Malignant lymphomas constituted 46.5% of all cases, of which 30.1% were Burkitt′s lymphoma, 9.8% were Non-Hodgkin (non Burkitt′s lymphoma and 6.6% were Hodgkin lymphoma. Retinoblastoma was the second most common malignancy constituting 15.2% of all cases, followed by Nephroblastoma 12.5% and acute leukemia′s accounted for 14.1% of all cases. Others were Neuroblastoma 5.5%, Rhabdomyosarcoma 1.9% and CNS and Hepatissc tumors 4.3%. About 80% of parents of these children are very poor and could not afford the cost of treatment. Fifty one percent of the patients were alive at 12 months and the mortality was 24%. Conclusion: Childhood cancer is common in Kano. Free treatment is what is required since majority of the parents could not afford the cost of treatment.

    Physiologic bowel activity on In-111 octreotide imaging is commonly seen. However, on occasion, normal bowel activity may mimic lesions in the abdomen, which can be very difficult to differentiate, particularly after surgical intervention. We report a case of focal bowel activity simulating a lesion in a patient who had an In-111 octreotide scan (Octreoscan), postoperatively, looking for recurrent carcinoid. SPECT/CT demonstrated that the uptake was localized in the anterior abdomen, and corresponded to a loop of bowel within a ventral hernia at the site of surgical incision. The correlation with CT as well as the precise localization made possible by the fusion images helped avoid misinterpretation of this finding as possible recurrent carcinoid. PMID:21637071

    A case of middle ear mass in a young female from Ireland is described, who presented with left ear hearing loss and intermittent bloody discharge from the same ear. Examination under microscope revealed occlusive polyp in the left ear and a biopsy had been taken under general anaesthesia. Histopathology report described an adenoma \\/ carcinoid tumour of the middle ear confirmed by positive immunohistochemical staining. CT temporal bones revealed the extension of the disease. The patient underwent left tympanotomy and excision of the tumour. In general, these tumours are regarded as benign but may be mistaken for adenocarcinomas because of their histological heterogenecity.

    Childhood central nervous system tumor survivors (CCNSTS) are at risk for adverse health issues. Little research has been conducted to explore the role of parental factors in weight management to mitigate adverse health outcomes. We conducted 9 group interviews (n=20) with CCNSTS, their parents, and health care providers to ascertain parental factors that may influence weight management practices in CCNSTS. Three main themes were identified: parenting style, parent-child connectedness, and food and physical activity (PA) environment. Although most parents adopted an authoritative parenting style related to diet and PA practices, some adopted a permissive parenting style. Participants expressed high levels of connection that may hinder the development of peer relationships and described the food and PA environments that promote or hinder weight management through parental modeling of healthy eating and PA and access to healthy food and activities. Weight management interventions for CCNSTS may experience greater benefit from using a family-focused approach, promoting positive food and PA environments, parental modeling of healthy eating and exercise, and partnering with youth to adopt weight management behaviors.

    Full Text Available We report a rare case of a laparoscopic splenectomy performed for a carcinoid metastasis. The patient represented with pleuritic left-sided chest pain from pleural deposits 9 years following resection of a primary lung carcinoid tumour. They were found to have a 4.7 cm splenic lesion on CT with a probable left acetabular metastasis demonstrated on Gallium PET scan. The patient underwent laparoscopic splenectomy for debulking treatment of the splenic lesion that was confirmed to be a splenic metastasis of the resected carcinoid lung tumour. Following an uncomplicated recovery, the patient was discharged on the second postoperative day. On discharge, she received adjuvant therapy with Lutetium 177 DOTATATE. This is the first report of a carcinoid splenic metastasis successfully treated with laparoscopic splenectomy.

    2016-01-01

    Carcinoid tumour is a well-known primary endobronchial lung neoplasm. Although calcifications may be seen in up to 30% of pulmonary carcinoid tumours, near complete ossification of these tumours is an unusual finding. Such lesions can prove diagnostically challenging at the time of intraoperative frozen section as the latter technique requires thin sectioning of the lesion for microscopic assessment. We present an unusual case of endobronchial carcinoid tumour with extensive ossification in a 45-year-old male. Preliminary intraoperative diagnosis was achieved through the alternative use of cytology scrape smears. The final diagnosis was confirmed after decalcification of the tumour. The prognostic implications of heavily ossified carcinoid tumours remain elusive. Long-term clinical follow-up of these patients is recommended. PMID:27610135

    Data from 1218 cases of childhood brain tumors (CBT) diagnosed between 1976 and 1994 and 2223 matched controls from the general population were included in an analysis of maternal beauty product exposure and beauty-related employment in 9 centers in 7 countries. A 50% increased odds ratio (OR) [95% confidence interval (CI) = 1.0-2.1] for CBT was observed among children of mothers who were exposed via personal use of and/or possible ambient contact with beauty products during the 5 years preceding the index child's birth compared with children of mothers never exposed to beauty products during this time period. Overall maternal personal use of hair-coloring agents in the month before or during the pregnancy of the index child's birth was not associated with CBT (OR = 1.0, CI = 0.83-1.3) or with astroglial (OR = 1.1, CI = 0.85-1.4), PNET (OR = 1.0, CI = 0.71-1.5) and other glial subtypes (OR = 1.0, CI = 0.62-1.0). Similarly, no statistically increased ORs or discernable pattern of risk estimates were observed for period of use or for number of applications per year for maternal personal use of hair-coloring agents overall or by histologic type. Among children born on or after 1980, increased ORs for CBT were associated with maternal non-work-related exposure to any beauty products (OR = 2.6, CI = 1.2-5.9), hair-dyes (OR = 11, CI = 1.2-90), and hair sprays (OR = 3.4, CI = 1.0-11). No overall increased OR for CBT was observed among children of mothers employed in beauty-related jobs during the 5 years preceding the index child's birth compared with those who reported no beauty-related employment. In general, other specific beauty product-related exposures were not associated with increased ORs for CBT. Data from our study provide little evidence of an increased risk for CBT with mothers' exposures to beauty products.

    2016-01-01

    Carcinoid tumours arise in cells of the diffuse neuroendocrine system and can develop in a number of anatomical sites including the lungs and the gastrointestinal tract. There has been a move away from the use of the term carcinoid tumour to the more appropriate use of neuroendocrine tumour (NET) to highlight the potential for invasion and metastasis associated with some NETs. Although most cases are sporadic, 15-20% of cases are related to a hereditary syndrome, the most common of these being multiple endocrine neoplasia 1 (MEN1). Other hereditary syndromes include the following: von Hippel-Lindau (VHL), neurofibromatosis 1 and tuberous sclerosis complex (TSC), which are all associated with a germline mutation of the associated tumour suppressor gene and an autosomal dominant inheritance pattern. Familial small intestinal NET (SI NET) is a recently described condition which is also inherited in an autosomal dominant manner. There appears to be more than one causative gene; thus far, only the IPMK gene has been identified as a causative germline mutation. This was identified by carrying out whole-exome sequencing of germline and tumour DNA in a family with multiple members diagnosed with SI NET. Identification of NET predisposition genes in other families via these methods will allow the development of dedicated NET gene panels which can be used to screen NET patients and at-risk relatives for hereditary mutations. Close surveillance of at-risk individuals is important to detect NETs early when curative surgery can be offered and the morbidity and mortality of metastatic NETs can be avoided. PMID:27075353

    To present a patient diagnosed with pancreatic carcinoid that was extremely rare and produced an atypical carcinoid syndrome.We reported a 58-year old male patient who presented with long standing,prominent cervical lymphadenopathy and occasional watery diarrhea.Pathohistological and immunohistochemical examination of lymph node biopsy showed a metastatic neuroendocrine tumor,which was histological type A of carcinoid (EMA+,cytokeratin+,CEA-,NSE+,chromogranin A+,synaptophysin+,insulin-).Bone marrow biopsy showed identical findings.Primary site of the tumor was pancreas and diagnosis was made according to cytological and immunocytochemical analysis of the tumor cells obtained with aspiration biopsy of pancreatic mass (12 mm in diameter) under endoscopic ultrasound guidance.However,serotonin levels in blood and urine samples were normal.It is difficulty to establish the precise diagnosis of a "functionally inactive" pancreatic carcinoid and aspiration biopsy of pancreatic tumor under endoscopic ultrasound guidance can be used as a new potent diagnostic tool.

Specifically, disruption of brain white matter integrity and its relationship to intellectual outcomes in adult survivors of childhood brain tumors needs to be better understood.Fifty-four participants underwent diffusion tensor imaging in addition to structural MRI and an intelligence test (IQ. Voxel-wise group comparisons of fractional anisotropy calculated from DTI data were performed using Tract Based Spatial Statistics (TBSS on 27 survivors (14 treated with radiation with and without chemotherapy and 13 treated without radiation treatment on average over 13 years since diagnosis and 27 healthy comparison participants. Whole brain white matter fractional anisotropy (FA differences were explored between each group. The relationships between IQ and FA in the regions where statistically lower FA values were found in survivors were examined, as well as the role of cumulative neurological factors.The group of survivors treated with radiation with and without chemotherapy had lower IQ relative to the group of survivors without radiation treatment and the healthy comparison group. TBSS identified white matter regions with significantly different mean fractional anisotropy between the three different groups. A lower level of white matter integrity was found in the radiation with or without chemotherapy treated group compared to the group without radiation treatment and also the healthy control group. The group without radiation treatment had a lower mean FA relative to healthy controls. The white matter disruption of the radiation with or without chemotherapy treated survivors was positively correlated with IQ and cumulative neurological factors.Lower long-term intellectual outcomes of childhood brain tumor survivors are associated with lower white

Although reports have been published regarding carcinoid syndrome occurring alongside rheumatoid arthritis, no reports have been made on such a case. Initial presentation of carcinoid syndrome in this patient was insidious and atypical with few symptoms, including shortness of breath and long standing abdominal bloating. Several years later a sudden change in bowel habit prompted a colonoscopy with biopsy that revealed a carcinoid rectal polyp. The case we report describes a rare presentation of carcinoid syndrome in chronic psoriatic arthropathy.

    2012-01-01

    Acute kidney injury (AKI) is a rare complication of carcinoid syndrome. A 61-year-old man developed carcinoid syndrome 51 months after pneumonectomy for bronchial carcinoid, and 8 episodes of AKI 101 to 118 months after pneumonectomy. Serum chromogranin A and urine 5-hydroxyindoleacetic acid levels were elevated for more than 1 year before AKI occurred. Each episode was characterized by flushing, facial edema, mild diarrhea, necrosis of hepatic metastatic nodules, mild oliguria, hyponatremia, acidosis, hypokalemia, hypomagnesemia and hyperphosphatemia. He did not have elevated urine sodium levels or osmolality, hypotension or hypertension. Plasma levels of dopamine, epinephrine and norepinephrine, measured during a single episode, were markedly elevated. Serum creatinine levels returned to normal after most episodes. Hyponatremia persisted but was more severe during AKI. Elevated plasma levels of vasoactive substances other than 5-hydroxytryptamine, perhaps dopamine or other catecholamines, could explain recurrent AKI. The natriuretic effect of elevated plasma dopamine levels could explain chronic hyponatremia. PMID:22008780

    AIM: To assess the results of endoscopic mucosal resection with a ligation device (EMR-L) combined with three dimensional endoscopic ultrasonography (3D-EUS) using an ultrasonic probe for rectal carcinoids. In addition, diagnosis of the depth and size of lesions by EUS was evaluated.METHODS: Between January 2003 and March 2007,20 patients underwent EMR-L with 3D-EUS using an ultrasonic probe (group A). 3D-EUS was combined with EMR-L at the time of injection of sterile physiological saline into the submucosal layer. For comparison, 14 rectal carcinoids that had been treated by EMR-L with-out 3D-EUS between April 1998 and December 2002 were evaluated as historical controls (group B). EUS was conducted for all of the patients before treatment to evaluate tumor diameter and depth of invasion. The percentage of complete resection and the vertical resection margin were compared between the two groups.RESULTS: The depth of invasion upon histopathological examination was in complete agreement with the pre-operative findings by EUS. The tumor diameter determined by EUS approximated that found in the tissue samples. There were no significant differences in the gender, tumor sites or tumor diameters between the two groups. The rate of complete resection for groups A and B was 100% and 71%, respectively (P<0.05). The vertical resection margin of group A was longer than that of group B.CONCLUSION: EMR-L is effective as an endoscopic treatment for rectal carcinoids. In combination with 3D-EUS, safe and complete resection is further assured.

It differs from other primary pancreatic tumours in cytoarchitecture, immunocytochemistry and biologic behaviour. Recognition of this rare entity is of vital importance having considerable therapeutic and prognostic implications. We report a case of an exophytic, pancreatic body carcinoid tumour in a man who presented with abdominal pain. The diagnosis was established by histopathological examination of the core biopsy specimen. A surgical resection of the lesion was done successfully and the patient made a satisfactory recovery from the operation.

    A best evidence topic in cardiac surgery was written according to a structured protocol. We addressed the following question: in patients who are diagnosed with carcinoid heart disease (CHD), do valvular surgeries improve their prognosis? Fifty percent of the patients with clinically diagnosed carcinoid syndrome had cardiac involvement which was present either as valvular dysfunction or as cardiac metastases. These patients often require surgery due to their heightened risk of cardiac disease. Altogether 217 relevant papers were identified as a result of the below-mentioned search, of which 10 papers represented the best evidence to answer the question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses were tabulated. Of the patients who were identified to have carcinoid heart disease in different studies, 193 patients had valve procedure, mainly replacements at tricuspid, mitral and aortic valve positions and either valvuloplasty or replacement at pulmonary valve. Tricuspid and pulmonary valves represented the majority of the excised valves among patients undergoing valvular surgery for CHD. The pathology of carcinoid valve was attributed to the presence of plaque, causing thickening and retraction. Pure regurgitation was the most common finding in all the valves except pulmonary valve which had both stenosis and insufficiency. Thirty-day mortality was 17% (range 1-63%) and long-term survivors were reported to be alive at an average of 58 months (28-80 months) after the valve surgery. The evidence demonstrates that surgical intervention can lead to improved prognosis and reduce the symptoms of heart failure. Postoperative mortality was mainly due to the carcinoid disease itself and not as a complication of the surgery. Therefore, surgery could be considered for symptomatic palliation in carefully selected individuals.

    Childhood brain tumors (CBT) are the second most common childhood cancers, yet their etiology is largely unknown. We investigated whether maternal gestational intake of folate and vitamins B6 and B12 was associated with CBT risk in a nationwide case-control study conducted 2005-2010. Case children 0-14 years were recruited from all 10 Australian pediatric oncology centers. Control children were recruited by national random digit dialing, frequency matched to cases on age, sex, and state of residence. Dietary intake was ascertained using food frequency questionnaires and adjusted for total energy intake. Data from 293 case and 726 control mothers were analyzed using unconditional logistic regression. The odds ratio (OR) for the highest versus lowest tertile of folate intake was 0.70 [95% confidence interval (CI): 0.48, 1.02]. The ORs appeared lower in mothers who drank alcohol during pregnancy (OR = 0.45, 95% CI: 0.22, 0.93), mothers who took folic acid (OR = 0.67, 95% CI: 0.42, 1.06) or B6/B12 supplements (OR = 0.51, 95% CI: 0.25, 1.06) and in children younger than 5 years (OR = 0.50, 95% CI: 0.27, 0.93). These findings are consistent with folate's crucial role in maintenance of genomic integrity and DNA methylation. Dietary intake of B6 and B12 was not associated with risk of CBT. PMID:24897174

    Full Text Available We report a 19-year-old female admitted to the Emergency Room with excruciating right lower abdominal pain of 1-day duration. The abdominal examination revealed a soft, lax abdomen with rigidity and guarding in her right iliac fossa without abdominal defense. Apart from a leukocytosis of 18.3/mm3, the rest of her baseline investigations and imaging, including abdominal X-rays, abdominal and pelvic ultrasound and abdominal CT scan were unremarkable. Patient′s persistent pain prompted the treating surgeon to undertake exploratory laparotomy, which disclosed an inflamed Meckel′s diverticulum and a normal-looking appendix. Meckel′s diverticulectomy along with appendectomy was performed. The histopathological report demonstrated carcinoid tumor in the Meckel′s diverticulum with free resection margins, whereas appendix was reported to be normal. The patient had an uneventful recovery and was discharged home on the sixth postoperative day.

    Background: Pediatric primary spinal tumors (PST) are fairly uncommon, with little available data regarding incidence and outcomes. Materials and Methods: We conducted a retrospective review of the 22 consecutive patients less than 18 years old diagnosed with PST between March 1997 and May 2011 and treated at Chang Gung Children Hospital. All patients had undergone magnetic resonance imaging (MRI) for pre-operative evaluation and operations for PST. The extent of tumor removal was assessed by surgical report by the neurosurgeon or by post-operative MRI if available. Results: Ten of them had intramedullary tumors and 12 had intradural extramedullary tumors. All patients were treated with surgery to the primary site. A total of 15 patients underwent gross total tumor resection and seven patients received post-operative radiotherapy. Five patients received adjuvant chemotherapy for their primary tumor. Fourteen patients (64%) survived from study entry without tumor progression. Conclusions: PST encompassed a diverse group of pathologic entities that differ markedly based on the location and age of the children. Total resection of pediatric PST in children could be performed with acceptable risk and satisfactory long-term results.

    Kidney tumors represent 6.2% of malignant tumors in children. History, clinical course and radiological findings are necessary elements in the differential diagnosis of the different renal tumors. In the case of nephroblastoma, chemotherapy is based solely on the radiological diagnosis without prior histology. In therapy-optimizing studies of the Society of Pediatric Oncology and Hematology, preoperative chemotherapy is performed. Therapy monitoring is performed in the course of and after preoperative chemotherapy to verify tumor response. Radiological staging plays a significant role in deciding on further treatment and in operative planning. Three-dimensional visualization of the abdominal situs can assist preoperative planning. In summary, diagnostic imaging in renal tumors in children plays a role in differential diagnosis, staging, monitoring of therapy, and surgical planning. (orig.) [German] 6,2% der kindlichen Tumorerkrankungen betreffen die Nieren. Anamnese, Klinik und radiologischer Befund fuehren zur Differenzialdiagnose der verschiedenen Nierentumoren.

Im Rahmen der Therapieoptimierungsstudien der Gesellschaft fuer Paediatrische Onkologie und Haematologie wird eine praeoperative Chemotherapie durchgefuehrt. Waehrend und nach der praeoperativen Chemotherapie erfolgt bildgebend ein Therapiemonitoring, um ein Ansprechen des Tumors auf die Therapie zu belegen. Das radiologische Staging hat grosse Bedeutung fuer die weitere Therapie und beeinflusst die Operationsplanung. Die praeoperative Planung wird durch 3D-Visualisierung erleichtert. Die Relevanz der radiologischen Diagnostik von Nierentumoren im Kindesalter ergibt sich zusammenfassend aus Differenzialdiagnostik, Staging, Therapiemonitoring und Operationsplanung. (orig.)

  13. Amplification of 9q34 in childhood adrenocortical tumors: a specific feature unrelated to ethnic origin or living conditions

    Figueiredo B.C.

    2000-01-01

    Full Text Available Adrenocortical tumors (ACT in children under 15 years of age exhibit some clinical and biological features distinct from ACT in adults. Cell proliferation, hypertrophy and cell death in adrenal cortex during the last months of gestation and the immediate postnatal period seem to be critical for the origin of ACT in children. Studies with large numbers of patients with childhood ACT have indicated a median age at diagnosis of about 4 years. In our institution, the median age was 3 years and 5 months, while the median age for first signs and symptoms was 2 years and 5 months (N = 72. Using the comparative genomic hybridization technique, we have reported a high frequency of 9q34 amplification in adenomas and carcinomas. This finding has been confirmed more recently by investigators in England. The lower socioeconomic status, the distinctive ethnic groups and all the regional differences in Southern Brazil in relation to patients in England indicate that these differences are not important to determine 9q34 amplification. Candidate amplified genes mapped to this locus are currently being investigated and Southern blot results obtained so far have discarded amplification of the abl oncogene. Amplification of 9q34 has not been found to be related to tumor size, staging, or malignant histopathological features, nor does it seem to be responsible for the higher incidence of ACT observed in Southern Brazil, but could be related to an ACT from embryonic origin.

    International Nuclear Information System (INIS)

    In order to estimate the influence of radiotherapy on the intellectual development of children with brain tumor, we investigated the educational level of 21 patients with germ cell tumor who had undergone radiotherapy. They were divided into three groups in accordance with their age at the time of radiation; under school age group (under 6 years of age), elementary school age group (from 7 to 12 years of age), and junior high and high school age group (from 13 to 18 years of age). There were 2 cases in the under school age group, one of them graduated from high school and the other is presently a junior high school student. There were 5 cases in the elementary school age group. Three of these graduated from university, 1 is presently a university student and 1 is a high school student. There were 14 cases in the junior high and high school age group. Two of these are university students, 7 graduated from high school, 1 is presently a junior high school student, and 4 died because of tumor progression. The mean period of hospitalization of the patients who have been admitted to university was 63.0 days, and that of patients who have not been admitted university was 135 days. There is a statistical difference (p<0.05). It could be concluded that the period of hospitalization rather than radiotherapy seemed to influence the educational status of children with brain tumor.

    Full Text Available Purpose. The aim of this study was to evaluate long-term outcomes of sacrococcygeal germ cell tumors (SC-GCTs over a 15-year period. Materials and Methods. A retrospective review was conducted of all pediatric patients treated for SC-GCTs at our hospital from 1998 to 2012. Results. Fifty-seven patients were treated for SC-GCTs with the most common in Altman’s classification type I. Age at surgery ranged from one day to 5.6 years. Tumor resection and coccygectomy were primarily performed in about 84% of the cases. Pathology revealed mature, immature, malignant sacrococcygeal teratomas (SCTs, and endodermal sinus tumors (ESTs in 41 (72%, 4 (77%, 6 (10.5%, and 6 (10.5%, respectively. Recurrence of discase occurred in 3 of 41 patients with mature teratomas (7.3%; 2 recurrences with mature teratomas and one recurrence with EST. Five of 6 malignant SCTs and 3 of 6 ESTs responded well to the treatment. Alpha-fetoprotein (AFP level was elevated in both malignant teratomas and ESTs. No immediate patient death was noted in any of the 57 cases, but 4 patients with malignant tumors and distant metastasis succumbed at home within 2 years of the initial treatment. Conclusion. Benign SCTs have a significant recurrence rate of approximately 7%. Close follow-up with serial AFP level monitoring should be done for 5 years after initial tumor resection and coccygectomy. The survival rate for malignant SC-GCTs with distant metastasis was unfavorable in the present study.

  4. Brain Magnetic Resonance Imaging After High-Dose Chemotherapy and Radiotherapy for Childhood Brain Tumors

    International Nuclear Information System (INIS)

    Purpose: Brain necrosis or other subacute iatrogenic reactions has been recognized as a potential complication of radiotherapy (RT), although the possible synergistic effects of high-dose chemotherapy and RT might have been underestimated. Methods and Materials: We reviewed the clinical and radiologic data of 49 consecutive children with malignant brain tumors treated with high-dose thiotepa and autologous hematopoietic stem cell rescue, preceded or followed by RT. The patients were assessed for neurocognitive tests to identify any correlation with magnetic resonance imaging (MRI) anomalies. Results: Of the 49 children, 18 (6 of 25 with high-grade gliomas and 12 of 24 with primitive neuroectodermal tumors) had abnormal brain MRI findings occurring a median of 8 months (range, 2-39 months) after RT and beginning to regress a median of 13 months (range, 2-26 months) after onset. The most common lesion pattern involved multiple pseudonodular, millimeter-size, T1-weighted unevenly enhancing, and T2-weighted hyperintense foci. Four patients with primitive neuroectodermal tumors also had subdural fluid leaks, with meningeal enhancement over the effusion. One-half of the patients had symptoms relating to the new radiographic findings. The MRI lesion-free survival rate was 74% ± 6% at 1 year and 57% ± 8% at 2 years. The number of marrow ablative courses correlated significantly to the incidence of radiographic anomalies. No significant difference was found in intelligent quotient scores between children with and without radiographic changes. Conclusion: Multiple enhancing cerebral lesions were frequently seen on MRI scans soon after high-dose chemotherapy and RT. Such findings pose a major diagnostic challenge in terms of their differential diagnosis vis-a-vis recurrent tumor. Their correlation with neurocognitive results deserves further investigation

  5. Crossing of the physis by bone tumors and osteomyelitis in childhood

    International Nuclear Information System (INIS)

    We report five children, in whom MR imaging demonstrated early crossing of the physis and spread of the disease from the metaphysis to the epiphysis. Follow-up in three children with osteomyelitis showed that antibiotic therapy resulted in almost complete resolution of the changes in the physis, epiphysis and metaphysis. These observations challenge the concept of the physis as a barrier against the spread of tumors and infection. (orig./MG)

    Full Text Available Ependymal tumors are the third most common group of brain tumors in children, accounting for about 10% of all primary brain neoplasms. According to the current WHO classification, they comprise four entities with the most frequent ependymoma and anaplastic ependymoma. The most of pediatric tumors are located within the posterior fossa, with a tendency to infiltrate the vital brain structures. This limits surgical resection and poses a considerable clinical problem. Moreover, there are no appropriate outcome prognostic factors besides the extent of surgical resection. Despite definition of molecular subgroups, the majority of childhood ependymomas present a balanced genome, which makes it difficult to establish molecular prognostic factors.The purpose of our study was to explore whether miRNA expression could be used as prognostic markers in pediatric infratentorial ependymomas. We also performed a mRNA expression pattern analysis of NELL2 and LAMA2 genes, with immunohistochemical illustrations of representative cases. The miRNA and mRNA expression was measured in 53 pediatric infratentorial ependymomas using a real-time quantitative PCR.Three miRNAs were shown to efficiently differentiate between grade II and III ependymomas: miR-17-5p, miR-19a-3p, and miR-106b-5p. Survival analysis showed that the probabilities of overall (p = 0.036 and event-free survival (p = 0.002 were reduced with higher than median miRNA expression levels of miR-17-5p. Using multivariate analysis adjusted for patient's age, sex, tumor grade and localization, we showed statistically significant associations with event-free survival (p = 0004 and borderline statistical significance with overall survival (p = 0.057 for miR-17-5p. Correlation analysis of miR-19a, miR-17-5p, miR-106b revealed that their expression levels were significantly correlated with EZH2 expression, suggested marker of PFA ependymomas. Furthermore, lower expression level of LAMA2 mRNA was shown to be

    Full Text Available Context. Primary renal carcinoid tumours are rare. Their pathogenesis is unknown and the clinical presentation is similar to other renal tumours thus posing diagnostic dilemmas for clinicians. Objectives. To review the literature for case reports of primary renal carcinoids. Methods. Literature was extensively searched for case reports for primary renal carcinoids. Reports of metastatic carcinoids to the kidneys were excluded. Results. Approximately less than 90 cases of primary carcinoid tumours of the kidney have been reported in the literature. A total of 29 cases of primary renal carcinoids were reviewed. The mean age of presentation was 48 years (range 29–75 with both right kidney (48.3% and left kidney (44.8% being equally affected. 28.6% of the cases reviewed were diagnosed as an incidental finding. The mean followup time was 20 months with 73.1% of patients without evidence of disease after surgical treatment (radical or partial nephrectomy. Primary carcinoid tumours of the kidney are often well differentiated tumours. They are often misdiagnosed because of their rarity and similar presentation with other renal tumours. Conclusions. Primary carcinoid tumours of the kidney are rare tumours with an indolent course with frequent metastasis. Metastatic work up and followup is required in their management.

    We describe a case of meningeous malignancy in childhood, diagnosed by the Pediatric Department of the Cancer Hospital in Sao Paulo, Brazil, and do revise the world literature as well. The meningeous sarcoma (M S) is an extremely aggressive tumor, which appears in the central nervous system, at any age, but mainly in children. They represent a tiny percentage of brain tumors in children and sporadic cases are related in the world literature. Consequently, there are not enough clinical experiences about this distinct entity to allow the conclusion about which is the best therapeutic approach. (author)

    Metastasis of neuroendocrine tumor to the myocardium is rare. We present a case of 64-year-old woman, who presented initially with abdominal pain and large adnexal mass. The image-guided biopsy showed low-grade neuroendocrine tumor with Ki67 less than 2% within the ovarian tissue. CT staging revealed bilateral adnexal masses, liver metastases, and primary lesion in the terminal ileum. Octreoscan showed marked tracer uptake within the lower esophagus not related to obvious mass on CT scan; the echocardiography confirmed the presence of a 2.7 cm LV/LA mass. In this case, close correlation between ECHO and the octreoscan obviated need for myocardial biopsy. PMID:26164175

    Full Text Available Background : Endoscopic third ventriculostomy (ETV the main alternative to ventriculoperitoneal shunt (VPS is just beginning to have a foothold in West Africa. It provides a great opportunity for a hydrocephalic child to be shunt free. The purpose of this paper is to compare outcome following ETV and VPS (using the cheap Chhabra shunt in children with noncommunicating non-tumoral hydrocephalus in an environment where late presentation is the norm. Materials and Methods : Sixty-three pediatric patients (< 6 years with hydrocephalus who underwent a VPS or ETV at our hospital were included in this study. The study period was of 30 months (January 2006 till June 2008. Clinically successful outcome was defined as no event occurring during or after surgery that resulted in an alternate surgical procedure, or significant post-operative complication that includes death. All complications related to the procedures were also analyzed. Results : The outcome of surgical intervention was not significantly related to the gender, age of the patient at surgery, or type of surgery. The post-operative complication rate was similar in both groups. Conclusions : The clinical outcome of ETV is comparable to that of VPS, with the added benefit of no shunt-related problems; and being a short procedure, patient anesthesia and operation time, hospital stay, and cost are significantly reduced. We consider ETV to be the procedure of choice for the treatment of noncommunicating nontumoral hydrocephalus in the pediatric population.

    Full Text Available Testicular carcinoid tumours (TCT account for less than 1% of all testicular neoplasms. A 17-year-old male underwent radical orchiectomy for a painful indurated and increased in size right testicle; a mixed echogenic mass, with a central homogeneous area surrounded by a hypoechoic edge with calcifications was found at ultreasound with increased vascularity at color Doppler examination. Biochemical markers were within normal limits. These symptoms are not specific and the majority of TCT are only diagnosed on histopathology. Patients should undergo long-term biochemical and radiological follow-up given potential for delayed metastases, in one case 17 years after primary treatment.

    Pediatric focal low-grade brainstem tumors are associated with excellent prognosis. Surgical resection and conformal radiation therapy are front-line treatment options; radiation therapy (RT) serves as an excellent treatment for disease progression. Given high survival rates and limited research regarding functional outcomes, the current study examined neurocognitive outcomes in a group of low-grade brainstem glioma survivors. Forty-three survivors of focal low-grade brainstem gliomas underwent neurocognitive assessment (58 % male; median = 6.9 years at diagnosis; median = 14.9 years at latest assessment). Treatment included combinations of surgery, chemotherapy, and RT with 70 % ultimately receiving RT. Neurocognitive outcomes were evaluated through retrospective chart review. Intellectual and academic performance were significantly different from normative expectations (full scale IQ = 86.5 ± 16.8; reading comprehension = 91.3 ± 16.4; math reasoning = 88.2 ± 18.9; reference group = 100 ± 15). Further, the percentage performing below average exceeded the expected 16 % in the normative sample (full scale IQ = 43 %; reading comprehension = 37 %; math reasoning = 50 %). Mean parent ratings did not reflect concerns regarding internalizing and externalizing behaviors or executive functioning (internalizing = 54.9 ± 12.7; externalizing = 51.6 ± 14.6, global executive composite = 57.1 ± 16.0; reference group = 50 ± 10); however, the proportion with clinically elevated scores was higher than the expected 16 % (internalizing = 42 %; externalizing = 26 %; global executive composite = 38 %). Mean performance fell below average for visual-motor coordination (81.8 ± 13.2) and parent ratings of adaptive functioning (73.4 ± 24.2), with 65 and 62 % falling outside the average range, respectively. There were no significant differences between

    Carcinoid tumours arising in the presacral region are extremely rare and they are usually benign. We report the case of a 37-year-old black man with a clinically malignant carcinoid tumour (well differentiated endocrine carcinoma) occurring in a sacrococcygeal teratoma and already metastasised to pelvic nodes, liver and bone at the time of the initial diagnosis. Such an aggressive behaviour of the presacral carcinoid tumours has never been described. The derivation of these tumours from hindgut rests with reference to embryological development of the tailgut cysts is discussed. PMID:15788213

    Full Text Available We report herein a rare case of typical carcinoid occurring primarily in the epiglottis. The patient was a 70-year-old man. On initial examination, a polypoid lesion with irregular surface near the center right-hand side of the laryngeal surface of the epiglottis was observed, and a biopsy was performed. Pathological examination of the specimen suggested the possibility of adenocarcinoma. Surgical excision was performed by means of laryngomicrosurgery. A Weerda-type laryngoscope was used to open the larynx, supplemented by rigid nasal sinus surgery endoscopes, and the right-hand half of the epiglottis were excised was ensured using a CO2 laser. Postoperative pathological diagnosis was negative for adenocarcinoma and squamous cell cancer; typical carcinoid was diagnosed according to the World Health Organization criteria. Aspiration occurred postoperatively, swallowing training was therefore provided, and the patient was discharged from hospital 2 months after surgery when he was able to eat normally. As of 4 years after surgery, the patient remains under follow-up observation by means of PET-CT and neck, thoracic, and abdominal CT administered at appropriate intervals, but no findings indicating obvious recurrence or metastasis have been observed, and the patient displays good swallowing function.

    Tailgut cysts are developmental cysts that arise from remnants of the embryonic postanal gut and are typically located within the presacral, retrorectal space. Isolated cases of aberrant locations, including prerectal, perirenal, perianal, retrovesical, and subcutaneous locations, have been reported. Malignant transformations with the presence of adenocarcinomas or carcinoids have been recognized within these entities. It is well recognized that anterior sacrococcygeal abnormalities are present and are frequently caused by the slow-growing nature of the tailgut cysts and related mass effect; however, the authors are aware of no reports in the literature of isolated tailgut cysts within the thecal sac in direct contact with neural elements, without extension into the peritoneal cavity. In this case, a 28-year-old woman presented with progressive back pain, frequent urinary tract infections, and bowel dysfunction. She was found to have a purely intradural tailgut cyst with malignant transformation consistent with carcinoid. No peritoneal extension of her disease was found. The authors hypothesize that this is a rare developmental aberration that has not been commonly recognized and potentially has implications for embryological development. PMID:21250817

    The current WHO classification of neuroendocrine tumors (NET) differentiates between typical carcinoids (low grade NET), atypical carcinoids (intermediate grade NET) and small cell and large cell carcinomas (high grade NET) according to the prognosis. Neuroendocrine neoplasms (NEN) of the gastrointestinal tract and the pancreas are graded in an identical way. Together with the TNM system this enables a preoperative estimation of the prognosis in biopsies and fine needle aspirates. Well-differentiated tumors are graded into G1 tumors by the number of mitoses, tumors (2-20 mitoses/10 HPF, Ki-67 3-20 %). Discrepancies between the number of mitoses and the Ki-67 index are not uncommon and in these cases the higher value of the two should be applied. The more differentiated tumors of the G3 type have to be differentiated from undifferentiated carcinomas of the small cell type and large cell type with a much poorer prognosis. Prognosis relevant grading of thyroid cancers is achieved by special subtyping so that the G1-G3 system is not applicable. The rare cancers of the parathyroid gland and of the pituitary gland are not graded. Adrenal tumors also have no grading system. The prognosis is dependent on the Ki-67 index and with some reservations on the established scoring systems. PMID:27379621

    Full Text Available We report a case of large primary mesenteric carcinoid tum or which was 7x7x4 cm. The 60 yr s old patient presented with the complaint of an abdominal mass since 1 yr. On radiology she was found to have a complex density mass surrounded by mesenteric fat with clear planes. On histopathology it was confirmed to be a carcinoid tumour of benign natur e. Primary mesenteric carcinoid tumor is very rare. 90% of them are found in GI tract with secondary involvement of mesentry in 40 - 80% cases when the size is larger than 2 cm. In this case it was a primary mesenteric tumour as there was no evidence of any o ther tumor. And second distant metastasis rate reported as 80% to 90% when they are larger than 2cm. The large size, primary mesenteric location and no metastasis despite large size make our case unique and rare.

    Atypical teratoid/rhabdoid tumor rarely occurs in the CNS, though is most common in infants under two years of age. It is characterized by unique histologic features, has an extremely aggressive natural course, and is located mainly in the infratentorial region. Radiologically, it is difficult to distinguish from primitive neuroectodermal tumor or medulloblastoma. We report the radiologic findings of two cases of atypical teratoid/rhabdoid tumor.

    Neuroendocrine tumors may develop throughout the human body with the majority being found in the gastrointestinal tract and bronchopulmonary system. Neuroendocrine tumors are classified according to the grade of biological aggressiveness (G1–G3) and the extent of differentiation (well-differentiated/poorly-differentiated). The well-differentiated neoplasms comprise typical (G1) and atypical (G2) carcinoids. Large cell neuroendocrine carcinomas as well as small cell carcinomas (G3) are poorly-differentiated. The identification and differentiation of atypical from typical carcinoids or large cell neuroendocrine carcinomas and small cell carcinomas is essential for treatment options and prognosis. Pulmonary neuroendocrine tumors are characterized according to the proportion of necrosis, the mitotic activity, palisading, rosette-like structure, trabecular pattern and organoid nesting. The given information about the histopathological assessment, classification, prognosis, genetic aberration as well as treatment options of pulmonary neuroendocrine tumors are based on own experiences and reviewing the current literature available. Most disagreements among the classification of neuroendocrine tumor entities exist in the identification of typical versus atypical carcinoids, atypical versus large cell neuroendocrine carcinomas and large cell neuroendocrine carcinomas versus small cell carcinomas. Additionally, the classification is restricted in terms of limited specificity of immunohistochemical markers and possible artifacts in small biopsies which can be compressed in cytological specimens. Until now, pulmonary neuroendocrine tumors have been increasing in incidence. As compared to NSCLCs, only little research has been done with respect to new molecular targets as well as improving the classification and differential diagnosis of neuroendocrine tumors of the lung.

    Objective: To distinguish healthy from pathological tissues in pediatric patients with posterior cranial fossa tumors using calculated textural parameters from magnetic resonance images. Materials And Methods: We evaluated 14 pediatric patients with posterior cranial fossa tumors using the software MaZda to define the texture parameters in selected regions of interest representing healthy and pathological tissues based on T2-weighted magnetic resonance images. Results: There was a statistically significant difference between normal and tumoral tissues as well as between supposedly normal tissues adjacent and distant from the tumoral lesion. Conclusion: Magnetic resonance textural evaluation is an useful tool for determining differences among various tissues, including tissues that appear apparently normal on visual analysis. (author)

    Soft tissue tumors of the knee are rare in childhood. Modern imaging modalities are very useful to evaluate these tumors. Their diagnosis has to be considered in view of the clinical content, their precise location and imaging features. Succinct review of the normal anatomy of the knee is made. We offer a diagnostic approach to these tumors in children including conventional radiology, ultrasound and MRI. We discuss the role of the different imaging techniques available for the diagnosis of these lesions, including pseudo-tumors such as popliteal cysts, hematoma, ossifying myositis, extra-articular benign and malignant tumors, as well as intra-articular lesions, synovial lipoma, osteochondromatosis and pigmented villo-nodular synovitis. MRI is particularly useful to evaluate the extent of the malignant tumors. (authors)

    The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF). MOBI-Kids, a multinational case–control study, investigates the potential effects of childhood and adolescent exposure to EMF from mobile communications technologies on brain tumor risk in 14 countries. The study, which aims to include approximately 1,000 brain tumor cases aged 10–24 years and two individually matched controls for each case, follows a common protocol and builds upon the methodological experience of the INTERPHONE study. The design and conduct of a study on EMF exposure and brain tumor risk in young people in a large number of countries is complex and poses methodological challenges. This manuscript discusses the design of MOBI-Kids and describes the challenges and approaches chosen to address them, including: (1) the choice of controls operated for suspected appendicitis, to reduce potential selection bias related to low response rates among population controls; (2) investigating a young study population spanning a relatively wide age range; (3) conducting a large, multinational epidemiological study, while adhering to increasingly stricter ethics requirements; (4) investigating a rare and potentially fatal disease; and (5) assessing exposure to EMF from communication technologies. Our experience in thus far developing and implementing the study protocol indicates that MOBI-Kids is feasible and will generate results that will contribute to the understanding of potential brain tumor risks associated with use of mobile phones and other wireless communications technologies among young people.

    Martos, R

    2012-02-01

    INTRODUCTION: Carcinoid heart disease is a rare condition in adults. Its diagnosis can be easily missed in a patient presenting to a primary care setting. We revised the advantages of using coronary multidetector computed tomography (MDCT) and cardiac magnetic resonance imaging (MRI) in diagnosing this condition. MATERIALS AND METHODS: We studied a 65-year-old patient with carcinoid heart disease and right heart failure using transthoracic Doppler-echocardiogram, cardiac MDCT and MRI. Cardiac echocardiogram revealed marked thickening and retraction of the tricuspid leaflets with dilated right atrium and ventricle. Cardiac MDCT and MRI demonstrated fixation and retraction of the tricuspid leaflets with delayed contrast hyperenhancement of the tricuspid annulus. CONCLUSION: This case demonstrates fascinating imaging findings of cardiac carcinoid disease and highlights the increasing utility of contrast-enhanced MRI and cardiac MDCT in the diagnosis of this interesting condition.

    2012-02-01

    BACKGROUND: Synchronous midgut carcinoids with gastrointestinal adenocarcinoma are a rare but recognised association. CASE PRESENTATION: The patient, a 74 year old woman, underwent anterior resection for a low rectal adenocarcinoma. Intra-operatively 3 serosal deposits of tumour were noted in the distal ileum. Histology revealed these to be ileal carcinoids. CONCLUSION: During resection of a gastrointestinal tumour, a thorough inspection of the abdominal cavity should be undertaken to investigate the possibility of metastatic secondaries or a synchronous tumour as is reported in this case.

    A malignant neuroendocrine tumour (carcinoid) of the spleen was diagnosed on post-mortem examination of a 3-year-old, male African pygmy hedgehog (Atelerix albiventris). The animal presented with a history of inappetence, weight loss, lethargy, a wide-based gait and a palpable abdominal mass. The gross pathological, histopathological, histochemical and immunohistochemical findings are described. Primary splenic carcinoids are reported rarely in the human medical literature and this is believed to be the first report in a non-human animal. PMID:27212029

    Rhabdomyosarcoma, osteosarcoma and Ewing's sarcoma are the most common malignant tumors of the musculoskeletal system in childhood and adolescence representing about 10% of newly diagnosed cancers in children and adolescents. In the last two decades the prognosis of patients with such malignancies improved significantly. On the one hand because of the advances in chemotherapy and orthopedic surgery, on the other hand also because of the innovations in radiological diagnostics. The precise pre-therapeutical staging of tumors of the musculoskeletal system provides important prognostic information and has impact on the entire therapy management. During respectively after therapy, imaging is extremely important in the follow-up and in diagnosing a possible recurrent disease. Modern imaging diagnostics of musculoskeletal tumors basically consist of conventional X-ray, of computed tomography (CT) and magnetic resonance imaging (MRI), and of modalities of nuclear medicine such as szintigraphy, positron emission tomography (PET) and PET CT. (orig.) [German] Das Rhabdomyosarkom, das Osteosarkom und das Ewing-Sarkom sind die am haeufigsten auftretenden malignen Tumoren des Muskuloskelettalsystems im Kindes- und Adoleszentenalter. Diese Erkrankungen repraesentieren etwa 10% der bei Kindern und Jugendlichen neu diagnostizierten Tumoren. In den letzten beiden Jahrzehnten hat sich insgesamt die Prognose der Patienten mit solchen Malignomen deutlich gebessert. Einerseits aufgrund der Fortschritte in der Chemotherapie und orthopaedischen Tumorchirurgie, andererseits nicht zuletzt aufgrund der zahlreichen Innovationen der radiologischen Diagnostik. Das praezise praetherapeutische Staging von Tumoren des Muskuloskelettalsystems liefert wichtige prognostische Informationen und beeinflusst das gesamte Therapiemanagement. Waehrend bzw. nach erfolgter Therapie ist die Bildgebung ganz entscheidend im Follow-up und bei der Diagnostik einer moeglichen Rezidiverkrankung. Die moderne

  6. Fertility and Pregnancy Outcome After Abdominal Irradiation That Included or Excluded the Pelvis in Childhood Tumor Survivors

    International Nuclear Information System (INIS)

    Purpose: To evaluate fertility after abdominal and/or pelvic irradiation in long-term female survivors. Methods and Materials: Puberty and pregnancy outcome were analyzed in female survivors of childhood cancer (aged <18 years) treated with abdominal and/or pelvic radiotherapy (RT) at one of two French centers (Nancy and Lyon) between 1975 and 2004. Data were obtained from medical records and questionnaires sent to the women. Results: A total of 84 patients who had received abdominal and/or pelvic RT during childhood and were alive and aged more than 18 years at the time of the study made up the study population. Of the 57 female survivors treated with abdominal RT that excluded the pelvis, 52 (91%) progressed normally through puberty and 23 (40%) had at least one recorded pregnancy. Of the 27 patients treated with pelvic RT, only 10 (37%) progressed normally through puberty and 5 (19%) had at least one recorded pregnancy. Twenty-two women (seventeen of whom were treated with pelvic RT) had certain subfertility. A total of 50 births occurred in 28 women, with one baby dying at birth; one miscarriage also occurred. There was a high prevalence of prematurity and low birth weight but not of congenital malformations. Conclusions: Fertility can be preserved in patients who undergo abdominal RT that excludes the pelvis, taking into account the other treatments (e.g., chemotherapy with alkylating agents) are taken into account. When RT includes the pelvis, fertility is frequently impaired and women can have difficulty conceiving. Nevertheless, pregnancies can occur in some of these women. The most important factor that endangers a successful pregnancy after RT is the total dose received by the ovaries and uterus. This radiation dose has to be systematically recorded to improve our ability to follow up patients.

    Opinion statement Neuroendocrine tumors (NETs) are a heterogeneous group of malignancies characterized by variable but most often indolent biologic behavior. Well-differentiated NETs can be broadly classified as either carcinoid or pancreatic NET. Although they have similar characteristics on routine histologic evaluation, the 2 tumor subtypes have different biology and respond differently to treatment, with most therapeutic agents demonstrating higher response rates in pancreatic NETs compar...

    2015-01-01

    Full Text Available Purpose: To report a case of vitrectomy performed in a child with dense massive vitreous hemorrhage due to secondary acute myelogenous leukemia (AML and tumor lysis syndrome. Case: A 4-year-old boy with clear-cell renal cell carcinoma was successfully treated with chemotherapy in 2011. However, in May 2012, he developed secondary AML. Although he was treated with combined chemotherapy and radiation, tumor lysis syndrome occurred with renal and heart failure complications. After an ultrasound examination by pediatricians found bilateral subretinal protrusions, he was referred to our clinic. Fundus examinations confirmed that the protrusions were bilateral subretinal or choroidal hemorrhages. A few weeks later, dense vitreous hemorrhages occurred bilaterally, and he completely lost vision in both eyes. Electroretinograms were extinguished in both eyes. After improvement of his general condition, we performed a 25-gauge vitrectomy combined with lens extraction in his left eye in December 2012. After removal of the vitreous hemorrhage, we found the subretinal hemorrhage had already been absorbed, leaving a mottled fundus color. However, the optic disc was not pale. Nine months after the surgery, his best-corrected visual acuity finally improved to 0.1. Conclusion: We successfully treated a case of severe vitreous hemorrhage secondary to leukemia therapy and tumor lysis syndrome using 25-gauge vitrectomy. This procedure may be safe and effective to perform, even in children with complications.

    Objective of this article is to appraise diagnostic aspects and treatment modalities in childhood ovarian tumor in background of available evidence. Literature search on Pubmed revealed various aspects of epidemiology, histopathological diagnosis, and treatment of pediatric ovarian tumor. 85 % of childhood tumors are germ cell tumors. The varied histopathological picture in germ cell tumors poses a diagnostic and therapeutic challenge. Immunohistochemistry and newer genetic markers like SALL4 and karyopherin-2 (KPNA2) have been helpful in differentiating ovarian yolk sac tumor from dysgerminoma, teratomas, and other pictures of hepatoid, endometrioid, clear cell carcinomatous, and adenocarcinomatous tissues with varied malignant potential. Before platinum therapy, these tumors were almost fatal in children. Fertility-conserving surgery with bleomycin, etoposide, and cisplatin has dramatically changed the survival rates in these patients. This modality gives cancer cure with healthy offspring to female patients with childhood ovarian tumor. Evidence also supports this protocol resulting in successful pregnancy rates and safety of cytotoxic drugs in children born to these patients. PMID:24757335

    Peptide receptor radionuclide therapy (PRRT) for the treatment of neuroendocrine tumours (NET) has been explored for almost two decades, but there are still few trials that have exclusively investigated well-differentiated and moderately differentiated NET arising from the respiratory tree. Thus, the aim of this study was to explore the outcome in patients affected by bronchopulmonary carcinoid (BPC) following PRRT. We retrospectively analysed 114 patients with advanced stage BPC consecutively treated with PRRT at the European Institute of Oncology, Milan, from 1997 to 2012 and followed until October 2014. The objective responses, overall survival (OS) and progression-free survival (PFS) were rated, and three different PRRT protocols ({sup 90}Y-DOTATOC vs. {sup 177}Lu-DOTATATE vs. {sup 90}Y-DOTATOC + {sup 177}Lu-DOTATATE) were compared with regard to their efficacy and tolerability. The median OS (evaluated in 94 of the 114 patients) was 58.8 months. The median PFS was 28.0 months. The {sup 177}Lu-DOTATATE protocol resulted in the highest 5-year OS (61.4 %). Morphological responses (partial responses + minor responses) were obtained in 26.5 % of the cohort and were associated with longer OS and PFS. The {sup 90}Y-DOTATOC + {sup 177}Lu-DOTATATE protocol provided the highest response rate (38.1 %). Adverse events were mild in the majority of patients. However, haematological toxicity negatively affected survival. No severe (grade 3/4) serum creatinine increase was observed. Patients treated with {sup 90}Y-DOTATOC alone more frequently showed a mild/moderate decrease in renal function. In patients treated with chemotherapy before PRRT had a shorter OS and PFS, and a higher risk of developing nephrotoxicity. In a large cohort of patients with advanced BPC treated in a ''real-world'' scenario and followed up for a median of 45.1 months (range 2 - 191 months), PRRT proved to be promising in prolonging survival and delaying disease progression.

    Tumor lysis syndrome (TLS) occurs in malignancies with high proliferative potential and tumor burden, such as lymphomas and leukemias. TLS syndrome is an oncologic emergency, requiring prompt intervention. The metabolic derangements cause acute kidney failure and may lead to cardiac arrhythmias, seizures, and death. With the advent of rasburicase, a recombinant urate oxidase, there has been a decline in the TLS-mediated renal failure and the need for dialysis. The recommended regimen and doses pose a heavy financial burden for patients in developing countries like India. With data and studies proving a similar efficacy for the reduced dose and lesser number of rasburicase, we report here a case series of seven children with acute leukemias, whose TLS was managed by a single dose of rasburicase. A retrospective analysis of case records of seven children with acute lymphoblastic leukemia and TLS, admitted to our Pediatric Oncology Unit of our Hospital between the period 2011 and 2013, was done. All our patients responded to a single dose, indicating that in appropriately monitored patients, single dose followed by as-needed dosing can be cost-saving. PMID:25838646

    Full Text Available Abstract Introduction Multiple endocrine neoplasia type 1 (MEN-1 patients are prone to develop carcinoid tumors. Few cases report the development of gastrointestinal carcinoid tumors in patients with MEN-1 syndrome related tumors. This is the first paper to report the occurrence of an intestinal carcinoid tumour in association with a pituitary adenoma. Case presentation A sixty eight year old female presented with intestinal obstruction four years after transphenoidal pituitary resection for pituitary adenoma. During surgical exploration and lysis of adhesions, we accidentally discovered an intestinal carcinoid tumour. Resection of the involved small bowel segment and the draining lymph nodes was undertaken. Postoperative follow up showed no biochemical or radiological evidence of residual tumor. Neuroendocrine tumors (NETs may occur as part of familial endocrine cancer syndromes including MEN-1. It is recommended that clinicians search thoroughly for MEN-1 in patients presented with NETs, however, there is no current consensus for screening patients suspected to have MEN-1 to rule out NET. Conclusion We recommend screening patients suspected to have any familial type of endocrine tumors for the presence of NET.

    Full Text Available Ectopic ACTH-syndrome is the most diagnostically challenging  variant of endogenous hypercortisolism. Particularly difficult differential diagnosis of this syndrome is from Cushing's disease (CD, as currently there is no single test sufficiently accurate to differentiate accurately ectopic ACTH production from the pituitary. The main functional tests are based on the fact that the vast majority of ectopic ACTH production is autonomous and suppresses one from pituitary. But in some cases this is not observed, and then the data obtained all necessary laboratory and instrumental research evidence in favor of central genesis of CD in a patient with ACTH ectopic secretion, which can lead to inappropriate treatment. If you confirm the ectopic ACTH-syndrome, it may take quite a long time of searching for the pathological focus, as there is no sufficiently precise imaging and diagnostic method for determining the localization of ectopic source of ACTH production. Thus, the differential diagnosis of ACTH-dependent hypercortisolism and localization of the ectopic tumor is the cornerstone of early and radical treatment of patients. We present a difficult clinical case of a patient having a pituitary hyperplasia with excessive ACTH expression with primary ectopic ACTH syndrome caused by lung carcinoid.

  18. Thyroid-Stimulating Hormone Suppression for Protection Against Hypothyroidism Due to Craniospinal Irradiation for Childhood Medulloblastoma/Primitive Neuroectodermal Tumor

    International Nuclear Information System (INIS)

    Purpose: Hypothyroidism is one of the earliest endocrine effects of craniospinal irradiation (CSI). The effects of radiation also depend on circulating thyroid-stimulating hormone (TSH), which acts as an indicator of thyrocyte function and is the most sensitive marker of thyroid damage. Hence, our study was launched in 1998 to evaluate the protective effect of TSH suppression during CSI for medulloblastoma/primitive neuroectodermal tumor. Patients and Methods: From Jan 1998 to Feb 2001, a total of 37 euthyroid children scheduled for CSI for medulloblastoma/primitive neuroectodermal tumor underwent thyroid ultrasound and free triiodothyronine (FT3), free thyroxine (FT4), and TSH evaluation at the beginning and end of CSI. From 14 days before and up to the end of CSI, patients were administered L-thyroxine at suppressive doses; every 3 days, TSH suppression was checked to ensure a value <0.3 μM/ml. During follow-up, blood tests and ultrasound were repeated after 1 year; primary hypothyroidism was considered an increased TSH level greater than normal range. CSI was done using a hyperfractionated accelerated technique with total doses ranging from 20.8-39 Gy; models were used to evaluate doses received by the thyroid bed. Results: Of 37 patients, 25 were alive a median 7 years after CSI. They were well matched for all clinical features, except that eight children underwent adequate TSH suppression during CSI, whereas 17 did not. Hypothyroidism-free survival rates were 70% for the 'adequately TSH-suppressed' group and 20% for the 'inadequately TSH-suppressed' group (p = 0.02). Conclusions: Thyroid-stimulating hormone suppression with L-thyroxine had a protective effect on thyroid function at long-term follow-up. This is the first demonstration that transient endocrine suppression of thyroid activity may protect against radiation-induced functional damage

    2014-02-01

    A 49-year-old man was referred with constipation that had lasted for a few months. On colonoscopy, a subepithelial tumour more than 4 cm in size was seen in the rectum. He underwent endoscopic ultrasound and pelvic magnetic resonance imaging. He was preoperatively diagnosed with a rectal duplication cyst based on imaging studies. However, the final histopathologic diagnosis after transanal excision of the rectal mass was rectal carcinoid tumour with tailgut cyst. Tailgut cysts are very rare congenital lesions in the presacral area and are most often discovered incidentally in middle-aged women. It is difficult to distinguish the imaging appearance of tailgut cysts from that of many other retrorectal cysts. Malignant transformation of tailgut cysts has been estimated to occur in 2 to 13% of cases. We report the diagnostic difficulties encountered in a case of carcinoid tumour arising from a tailgut cyst in a male patient. PMID:24434858

    2007-01-01

    Full Text Available Background/Aim. Autoimmune atrophic fundic gastritis induces the pernicious anemia (PA, as well as the changes in both epithelium and endocrine cells of gastric mucosa. The most important complications are: achlorhydria, hypergastrinemia, gastric cancer and enterochromaffin-like ( ECL carcinoid. The aim of this study was to examine ECL carcinoid histogenesis in A-gastritis associated with PA. Methods. During the period from 2000−2006, 65 patients with PA and 30 patients of the control group were examined. Histopathological examination was done in endoscopical biopsies of gastric mucosa fixed in 10% formaldehyde. Paraffin sections were stained with classic hematoxylin-eosin (HE; histochemical AB-PAS (pH 2.5, cytochemical argyrophilic Servier-Munger′s and immunocytochemical PAP methods for G cell identification and chromogranin A antibodies - specific marker for neuroendocrine ECL cells. Both G and ECL cells were counted per 20 fields, of surface 0.0245312 mm2 by a field. Basal gastrin serum levels were also examined by using radioimmunoassay (RIA method. The obtained results were statisticaly calculated by using Student΄s t test. Results. Marked antral G cell hyperplasia associated with corporal ECL hyperplasia was found. ECL cell hyperplasia was of simplex, linear, adenomatoid type to the pattern of intramucous ECL cell carcinoid. An average number of G cells was statistically significant in the patients with PA as compared to the control group (p < 0.05 as well as an average number of ECL cells. Conclusion. We concluded that antral G cell hyperplasia accompanied by gastrinemia induces ECL hyperplasia and ECL corporal carcinoid in A-gastritis and that their histogenesis develops trough simple, linear and adenomatoide hyperplasia. .

  3. Unraveling tumor grading and genomic landscape in lung neuroendocrine tumors.

    2014-06-01

    Currently, grading in lung neuroendocrine tumors (NETs) is inherently defined by the histological classification based on cell features, mitosis count, and necrosis, for which typical carcinoids (TC) are low-grade malignant tumors with long life expectation, atypical carcinoids (AC) intermediate-grade malignant tumors with more aggressive clinical behavior, and large cell NE carcinomas (LCNEC) and small cell lung carcinomas (SCLC) high-grade malignant tumors with dismal prognosis. While Ki-67 antigen labeling index, highlighting the proportion of proliferating tumor cells, has largely been used in digestive NETs for assessing prognosis and assisting therapy decisions, the same marker does not play an established role in the diagnosis, grading, and prognosis of lung NETs. Next generation sequencing techniques (NGS), thanks to their astonishing ability to process in a shorter timeframe up to billions of DNA strands, are radically revolutionizing our approach to diagnosis and therapy of tumors, including lung cancer. When applied to single genes, panels of genes, exome, or the whole genome by using either frozen or paraffin tissues, NGS techniques increase our understanding of cancer, thus realizing the bases of precision medicine. Data are emerging that TC and AC are mainly altered in chromatin remodeling genes, whereas LCNEC and SCLC are also mutated in cell cycle checkpoint and cell differentiation regulators. A common denominator to all lung NETs is a deregulation of cell proliferation, which represents a biological rationale for morphologic (mitoses and necrosis) and molecular (Ki-67 antigen) parameters to successfully serve as predictors of tumor behavior (i.e., identification of pathological entities with clinical correlation). It is envisaged that a novel grading system in lung NETs based on the combined assessment of mitoses, necrosis, and Ki-67 LI may offer a better stratification of prognostic classes, realizing a bridge between molecular alterations

    Full Text Available Abstract Background Transarterial Chemoembolization (TACE has been recognized as a successful way of managing symptomatic and/or progressive hepatic carcinoid metastases not amenable to surgical resection. Although it is a fairly safe procedure, it is not without its complications. Case presentation This is a case of a 53 year-old woman with a patent foramen ovale (PFO and mild pulmonary hypertension who underwent TACE for progressive carcinoid liver metastases. She developed acute heart failure, due to a severe inflammatory response; this resulted in pneumatosis intestinalis due to non-occlusive mesenteric ischemia. We describe the successful non-operative management of her pneumatosis intestinalis and the role of a PFO in this patient's heart failure. Conclusion TACE remains an effective and safe treatment for metastatic carcinoid not amenable to resection, this case illustrates the complexity of complications that can arise. A multi-disciplinary approach including ready access to advanced critical care facilities is recommended in managing such complex patients.

  5. Acute Inflammatory Bowel Disease Complicating Chronic Alcoholism and Mimicking Carcinoid Syndrome

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available We report the case of a woman with a history of chronic alcohol abuse who was hospitalized with diarrhea, severe hypokalemia refractory to potassium infusion, nausea, vomiting, abdominal pain, alternations of high blood pressure with phases of hypotension, irritability and increased urinary 5-hydroxyindoleacetic acid and cortisol. Although carcinoid syndrome was hypothesized, abdominal computed tomography and colonoscopy showed non-specific inflammatory bowel disease with severe colic wall thickening, and multiple colic biopsies confirmed non-specific inflammation with no evidence of carcinoid cells. During the following days diarrhea slowly decreased and the patient’s condition progressively improved. One year after stopping alcohol consumption, the patient was asymptomatic and serum potassium was normal. Chronic alcohol exposure is known to have several deleterious effects on the intestinal mucosa and can favor and sustain local inflammation. Chronic alcohol intake may also be associated with high blood pressure, behavior disorders, abnormalities in blood pressure regulation with episodes of hypotension during hospitalization due to impaired baroreflex sensitivity in the context of an alcohol withdrawal syndrome, increased urinary 5-hydroxyindoleacetic acid as a result of malabsorption syndrome, and increased urinary cortisol as a result of hypothalamic-pituitary-adrenal axis dysregulation. These considerations, together with the regression of symptoms and normalization of potassium levels after stopping alcohol consumption, suggest the intriguing possibility of a alcohol-related acute inflammatory bowel disease mimicking carcinoid syndrome.

    Somatostatin analogs are used in the control of hormonal hypersecretion and tumor growth of patients with acromegaly, islet cell carcinomas and carcinoids. Recently we showed that somatostatin receptor positive tumors can be visualized in vivo after the administration of radionuclide-labeled somatostatin analogs. Receptor imaging was positive in 18/21 islet cell tumors, 32/37 carcinoids, 26/28 paragangliomas, 9/14 medullary thyroid carcinomas, and 5/7 small cell lung cancers. Somatostatin receptor imaging is an easy, harmless and painless diagnostic method. It localizes multiple and/or metastatic tumors, predicts the successful control of hormonal hypersecretion by octreotide and seems to be of prognostic value in certain types of cancer. This scintigraphic method might help in patient selection for clinical trials with somatostatin analogs in the treatment of neuroendocrine cancers. (orig.).

  12. Childhood proptosis

    International Nuclear Information System (INIS)

    Proptosis in children is a hallmark of orbital diseases which can present a diagnostic challenge requiring thoughtful investigation. The aim of this review is to provide the reader an overview of the subject of childhood proptosis with an emphasis on the systematic and practical approach for the work-up of proptosis in children. Use of proper imaging studies is essential for the correct diagnosis. Computed tomography is a good screening test for any space occupying lesion of the orbit. Proptosis describes eye prominence due to space occupying orbital lesions. Congenital lesions usually present in the first decade of life. Acquired orbital lesions such as lymphangiomas, orbital varix, rhabdomyosarcoma and neural tumors may present at the end of the first decade of life. Metastatic tumors to the orbit, adenocarcinoma of lacrimal gland and rapidly growing masses may present with proptosis associated with pain. Visual loss can be the presenting symptoms in the patients with optic nerve (ON) gliomas, orbital meningiomas and posteriorly located tumors. Cystic lesions of the orbit may be congenital or acquired, dermoid cysts being the most common congenital orbital lesions. Some of the vascular lesions of the orbit include capillary hemangiomas, lymphangiomas, orbital varix, and arteriovenous malformations. Inflammatory process of the orbit in children include cellulitis and pseudotumor. Neural tumors such as neurofibromas, ON gilomas and meningiomas are less common causes of proptosis in children. Rhabdomyosarcoma is the most common primary orbital malignancy in children which can present with acute proptosis and is one of the few life-threatening diseases seen initially by an ophthalmologist. Secondary orbital tumors invade the orbit from adjacent sinuses, cranium or extended from the eye itself. The most common distant metastases in children include neuroblastoma and Ewing's sarcoma. Although many orbital processes can be diagnosed based on history, clinical

    Central sensitization defines a state of amplified sensory input within the nervous system across many organ systems; it overlaps syndromes as fibromyalgia, chronic fatigue, irritable bowel, and interstitial cystitis. Commonly, individuals will experience multiple syndromes during the course of their lifetime. A 62-year-old patient presented for evaluation of multiple medically unexplained symptoms postsurgically including chronic left chest wall and flank pain with concomitant diarrhea, abdominal pain, and facial flushing. After extensive multidisciplinary evaluations, he was diagnosed as having central sensitization in which the initial presentation mimicked carcinoid syndrome. He was subsequently treated with extensive multidisciplinary pain rehabilitation, and it did well. PMID:27144900

  20. Bronchoplasty for Primary Broncho-Pulmonary Tumors

    Parenchyma-sparing procedures are widely used in patients with low-grade malignancies of the airway when anatomically suited lesions exist. This study was conducted to evaluate the short-term and the long-term results of bronchoplastic procedures for patients with centrally located primary bronchopulmonary tumors. Methods: Between 2000 and 2009, 36 patients with primary lung tumors required bronchoplasty were retrospectively analyzed. Preoperative assessment included computed tomography (CT) of the chest, bronchoscopy, and spirometry. Pre operative diagnosis was achieved by bronchoscopy for all patients, mediastinoscopy was done for patients with primary lung cancer. Neo adjuvant chemotherapy was given for 6 patients with non small cell lung cancer (NSCLC). Results: We had 15 males and 21 female, the mean age was 37 years and the mean hospital stay was 7.2 days. Operative procedures performed were:Sleeve lobectomy in 30 patients (13 right, 17 left), partial sleeve right pneumonectomy in 3 and bronchial resection with re-anastomosis in 3 (2 left, 1 right). Twelve patients (33.3%) suffered post-operative problems. There was one operative related mortality. Post operative pathology revealed: 27 patients with typical carcinoid, 2 with atypical carcinoid, 4 with squamous cell carcinoma, 2 with adenocarcifioma and one with hamartoma. Pathological TNM staging revealed: 17 patients with stage 1A, 11 with IB, 5 with IIA and 2 with stage IIIA. Follow-up data were available for all patients except two. Two patients died with disseminated disease 1.5 year and 2 years after surgery. The patient with hamartoma developed local recurrence 5 years later and re-excision was done. One patient with lung cancer developed bone metastases and was alive with disease, while the remaining 30 patient's were alive and disease free. The overall 5 years survival was 83.3%. Conclusion: Bronchoplastic resections achieve local control and long-term survival comparable to the standard resections in

    Full Text Available Neuroendocrine gastroenteropancreatic (GEP tumors are rather rare neoplasms with an incidence of 1-2 cases per 100,000 people [1, 2, 3, 4]. They originate from any of the various cell types belonging to the neuroendocrine system. A general characteristic of GEP endocrine tumors is that the vast majority produce and secrete a multitude of peptide hormones and amines. Several syndromes can be associated with GEP endocrine tumors, caused by hyperproduction of a specific hormone, and usually liver metastases are pre sent in patients because of the malignancy of the tumors [5, 6, 7, 8, 9, 10]. The syndromes include: carcinoid syndrome [10], Zollinger- Ellison syndrome [6], the so-called "insulinoma syndrome" [5], "glucagonoma syndrome" [7], Verner-Morrison syndrome, which is brought about by high circulating levels of vasointestinal peptide (VIP [8], and finally the "somatostatinoma syndrome" [9].

    Objective: To describe key imaging findings in a series of cases of primary neuroendocrine tumors of the lung (NTLs), with emphasis on computed tomography changes. Materials And Methods: Imaging studies of 22 patients (12 men, mean age 60 years) with histopathologically confirmed diagnosis, evaluated in the author's institution during the last five years were retrospectively reviewed by two radiologists, with findings being consensually described focusing on changes observed at computed tomography. Results: The authors have described five typical carcinoids, three atypical carcinoids, three large-cell neuroendocrine carcinomas (LCNCs), and 11 small-cell lung cancers (SCLCs). Only one typical carcinoid presented the characteristic appearance of central endobronchial nodule with distal pulmonary atelectasis, while the others were pulmonary nodules or masses. The atypical carcinoids corresponded to peripheral heterogeneous masses. One out of the three LCNCs was a peripheral homogeneous mass, while the others were ill-defined and heterogeneous. The 11 SCLCs corresponded to central, infiltrating and heterogeneous masses with secondary pleuropulmonary changes. Calcifications were absent both in LGNCs and SCLCs. Metastases were found initially and also at follow-up of all the cases of LCNCs and SCLCs. Conclusion: Although some imaging features may be similar, radiologic findings considered together with clinical information may play a relevant role in the differentiation of histological types of NTLs.

    Full Text Available Neuroendocrine tumors (NET represent approximately 20% of all primary neoplasms of the lung. Histologic confirmation is important for treatment and prognosis determination. NET are classified according to four subtypes in the lung: typical carcinoid tumor (TC, atypical carcinoid tumor (AC, small cell carcinoma (SCC, and large cell neuroendocrine carcinoma (LCNEC. TC is low-grade, AC is intermediate-grade, and SCC and LCNEC are high-grade malignancies. Case report: A 57 years old woman, affected by a cervical anterior tumor and a proliferative tissue below the glottis was referred to our Endocrinology Department from ENT service for a second opinion. An ultrasound scan of the neck showed a polynodular goiter with bilaterally lymph nodes enlargement with suspicious malignancy characters. She had undergone surgery for the cervical anterior mass and for the laryngeal biopsy. Histopathological examination results were consistent with a SCC; neoplastic cells showed immunoreactivity to synaptophysin, neuron specific enolase and chromogranin. The serum levels of serotonin, cromogranin A, calcitonin, carcinoembryonic antigen, ACTH, PTH, TSH, FT4 were normal. Fine needle aspiration biopsy of her left thyroid lobe nodule was performed and the cytopathological exam was compatible with a neuroendocrine tumor metastasis. Thoracic and abdominal computed tomography was normal at that moment. Chest CT revealed the primary pulmonary tumor at 6 months after presentation. The therapeutic option for advanced or metastatic NETs is mainly palliation of symptoms; options need to be individualized and, therefore, rely on the knowledge of multidisciplinary teams.

    CONCLUSION: It is concluded that the expression of PRAME and WT1 genes are indicators of favorable prognosis and can be useful tools for monitoring minimal residual disease (MRD in acute leukemia especially in patients without known genetic markers. Differential expression between acute leukemia patients and healthy volunteers suggests that the immunogenic antigens (PRAME and WT1 are potential candidates for immunotherapy in childhood acute leukemia.

    Full Text Available A case of a glomus tumor originating from the lung is reported. A 43-year-old female had undergone resection of a right lung tumor following a clinical diagnosis of carcinoid, sclerosing hemangioma, or other sarcoma. Histologically, the tumor comprised uniform small round to oval cells with centrally located nucleus, a clear cytoplasm, and apparent cell borders. The tumor also showed a focally hemangiopericytomatous pattern with irregularly branching or dilated vessels. Electron microscopy revealed smooth muscle differentiation of the tumor cells. Immunostaining further revealed that the tumor cells expressed smooth muscle actin, h-caldesmon, muscle specific actin (HHF-35, but not cytokeratin, epithelial membrane antigen, synaptophysin, or chromogranin A. Based on these findings, a diagnosis of primary pulmonary glomus tumor was established. Glomus tumors of the lung are very rare and only 21 cases have been reported to date. The histological features of the present tumor and the relevant literature are discussed.

  14. Radiation dose and relapse are predictors for development of second malignant solid tumors after cancer in childhood and adolescence: A population-based case-control study in the five Nordic countries

    International Nuclear Information System (INIS)

    The aim of the study was to assess the risk with radiation therapy and chemotherapy of the first cancer in childhood and adolescence for the development of a second malignant solid tumor (SMST). Also, the role of relapse of the primary tumor was studied. It is a nested case-control study within a Nordic cohort of patients less than 20 years of age at first diagnosis 1960-1987. SMSTs were diagnosed in 1960-1991. There were 196 cases and 567 controls. The risk was increased only for radiotherapy given more than five years before the development of the SMST. A significantly increased relative risk of 1.8 was found already at doses below 1 Gy. The risk increased rapidly up to a maximum of 18.3 for doses above 30 Gy. Chemotherapy alone did not increase the risk to develop an SMST. However, in combination with radiotherapy, chemotherapy showed a significant potentiating effect. Relapse was found to be an independent risk factor for development of an SMST, with a higher relative risk for females than for males

    1998-01-01

    We present the case of a 52-year old patient diagnosed with carcinoid tumour of the rectum with liver metastases in which treatment with somatostatin analogues (octreotide) proved very effective in the disappearance of the symptomatology and dramatic efficacy in the regression of the tumour. Imaging by octreoscan was always negative. The role of octreotide in the treatment of carcinoid tumour and the usefulness of In-111-pentetreotide (octreoscan) in the localization and prediction of the response to treatment with octreotide is discussed. We conclude that the negative result of the scintigraphic image with octreoscan does not necessarily suppose the inefficacy of octreotide treatment. We believe that this may constitute an important issue since some patients may be denied octreotide treatment in the absence of a positive octreoscan result. PMID:9710364

    The paper reviews the 2016 WHO classification of prostate tumors, notes the alterations made, and describes approaches to the diagnosis of cancer types and grades. It also gives original photomicrographs from the authors' collection. The main alterations were as follows: - The types of prostate adenocarcinoma were added by pleomorphic giant-cell carcinoma; oncocytic (8290/3) and lymphoepithelial (8082/3) carcinomas were excluded. - Grade III prostatic intraepithelial neoplasia (PIN) was substituted for high grade PIN (8148/2). - Intraductal carcinoma (8500/2) was added. - Basal cell adenoma (8147/0) was excluded. - Carcinoids were referred to as low-grade neuroendocrine tumors according to the current terminology; large cell neuroendocrine cancer (8013/3) was added. - Paraganglioma (8613/3) and neuroblastoma (9500/3) were excluded. Stromal tumors were grouped with mesenchymal neoplasms. -Malignant fibrous histiocytoma, malignant peripheral nerve sheath tumor, chondroma, and hemangiopericytoma were excluded. - Synovial sarcoma (9040/3), inflammatory myofibroblastic tumor (8825/1), osteosarcoma (9180/3), undifferentiated pleomorphic sarcoma (8802/3), solitary fibrous tumor (8815/1), and malignant solitary fibrous tumor (8815/3) were added. The section of lymphoproliferative diseases was extended. The tumors of unknown origin included paraganglioma and neuroblastoma from a group of neuroendocrine tumors. The TNM staging was completely consistent with the 2010 AJCC version. PMID:27600780

    The study describes the results of Octreoscan SPET (OCTSPET) qualitative and semi-quantitative evaluation in 38 patients with suspected pancreatic neuroendocrine tumors. SPET studies were acquired at 4 and 24 hours after the injection of 111-220 MBq of 111-In-pentetreotide (Octreoscan). Qualitative and semi-quantitative evaluations were performed. The semi-quantitative approach was based on the time course of Tumor/Non Tumor ratios (TNTinc) from 4 and 24 hours. The OCTSPET results were true positive in 18 of 19 patients (10 gastrinoma, 5 insulinoma, 1 neuroendocrine tumor, 1 glucagonoma and 1 carcinoid) and false negative in one insulinoma. Besides, 20 of 38 patients (52%) had clinical plans modified after OCTSPET; OCTSPET was the only positive diagnostic test in 14 of 19 patients (73%) and guided the surgery decision in 14 of 25 patients (56%). In conclusion, these data indicate that Octreoscan represents an excellent tool for the diagnosis of pancreatic neuroendocrine tumors. PMID:11789028

    Full Text Available Objective: We aimed to evaluate the value of somatostatin receptor imaging (SRI with In-111 octreotide and Ga-68 DOTATATE in localizing ectopic ACTH producing tumors. Methods: Nineteen patients who had In-111 octreotide somatostatin receptor scintigraphy (SRS and/or Ga-68 DOTATATE PET-CT to localize ectopic ACTH producing tumors between the years 2000 and 2012 were included retrospectively in our study. The results of SRI were compared with clinical onset, radiological findings and surgical data of the patients. Results: Sixteen In-111 octreotide SRS and five Ga-68 DOTATATE PET-CT were performed in 19 patients. In eight out of 19 patients, ectopic ACTH secretion site could be detected. In five patients, SRS showed pathologic uptake. In four of these patients, surgery revealed pulmonary carcinoid tumors and in one patient pancreatic neuroendocrine tumor. In one patient, Ga-68 DOTATATE PET-CT revealed pathologic uptake in lung nodule which came out to be pulmonary carcinoid tumor. In another patient who had resection of metastases of atypical carcinoid tumor prior to scans, new metastatic foci were detected both with SRS and Ga-68 DOTATATE PET-CT imaging. In one patient, although SRS was negative, CT which was performed three years later showed a lung nodule diagnosed as pulmonary carcinoid tumor. In 11 patients, ectopic ACTH secretion site could not be detected. In 10 of those patients, scintigraphic and radiological imaging did not show any lesions and in one patient, Ga-68 DOTATATE PET-CT was false positive. Conclusion: SRI has a complementary role with radiological imaging in localizing ectopic ACTH secretion sites. PET-CT imaging with Ga-68 peptide conjugates is a promising new modality for this indication.

  3. Common Diagnostic Challenges in the Histopathologic Diagnosis of Neuroendocrine Lung Tumors: A Case Report

    Directory of Open Access Journals (Sweden)

    Monica Valente

    2010-07-01

    Full Text Available Bronchopulmonary neuroendocrine tumors are an uncommon group of neoplasms, accounting for about 20% of all lung carcinomas, arising from stem cells of the bronchial epithelium known as Kulchitsky cells. In the past, these tumors were grouped among benign or less aggressive malignant pulmonary tumors. Currently, according to the 2004 World Health Organization categorization, these tumors are separated into 4 subtypes characterized by increasing biologic aggressiveness: low-grade (typical carcinoid; TC, intermediate-grade (atypical carcinoid; AC and high-grade (large-cell neuroendocrine carcinoma, LCNEC, and small-cell lung carcinoma, SCLC. They differ by morphologic, immunohistochemical and structural features. At histopathologic analysis, these tumors share progressive increase in a number of mitotic figures per 10 high-power fields and in the extent of necrosis, with TC having the lowest values and SCLC having the highest. TCs and ACs make up approximately 1–2% of all primary lung tumors. Differentiating ACs from TCs or LCNEC and SCLC is clinically important because the treatment modalities and prognoses for these types of tumors are different. We report a case of misdiagnosis of bronchopulmonary neuroendocrine tumor in a young woman which has heavily influenced her clinical history.

    Ninety three patients with obstructing tracheobronchial tumors were treated with Neodymium: Yttrium - Aluminum - Garnet (Nd:YAG) laser photocoagulation over a period of six years. There were sixty seven Males and 26 Females with a mean age of 44.3 years (range 6- 79 years). 21 benign and 72 malignant lesions were treated with a total 212 sessions of laser photocoagulation (mean 2.4 sessions). The anatomical distribution of lesions were as follows; larynx 9 (three benign and 6 malignant) trachea 39 (27 benign and 12 malignant) left main bronchus 27 (14 malignant) right main bronchus 24 (14 malignant) and vocal cords - 9 (three malignant). There were 21 patients with squamous cell carcinoma, two adenocarcinomas, one adenoid cystic carcinoma, 7 cases of locally infiltrating tumors from thyroid and esophagus, 6 cases of carcinoid tumor and 16 benign lesions. Twenty one patients had a tracheostomy tube in place when treatment was started. Eighteen of the 21 patients with tracheostomy were weaned off the tube in a mean of 5.5 days from the start of treatment. Lumen was restored in 31 (79.4%) patients. In the other eight (20.6%), lumen was achieved, but not sustained. Complications included bleeding in three cases which were managed conservatively, two cases of pneumothorax, and four cases of bronchospasm. There were six deaths during the follow up but none attributable to the procedure. Laser photocoagulation offered effective treatment in the majority of patients with obstructing tracheobronchial tumors, with acceptable morbidity.

    Full Text Available Neuroendocrine tumors most frequently involve the gastrointestinal tract and bronchopulmonary system. Few cases of presumed primary neuroendocrine tumors in the orbit have been reported so far and most of the orbital cases are actually metastatic. We describe the unusual occurrence of this tumor in the orbit of a 16-year-old boy. The lesion was initially thought to be primary; however, the diagnosis of a metastatic orbital lesion was later supported by the histopathological appearance of his orbital biopsy, characteristic immunohistochemical profile and the presence of a primary mediastinal tumor. The patient did not have any symptoms suggestive of a carcinoid syndrome during the course of his disease. Unfortunately, tests showed lymph node involvement and distant metastatic lesions and he died from these a few months later while on palliative therapy.

    Primary carcinoid tumor (well-differentiated neuroendocrine tumor) of the bone involving the sacrum is extremely rare. We report the case of a 72-year-old man who presented with a 20-year history of intermittent low back pain and was found to have an intraosseous sacral mass on imaging. A needle biopsy revealed that this lesion was a well-differentiated neuroendocrine tumor. Workup did not show any primary tumor or other metastatic disease. There was no associated tailgut cyst or sacrococcygeal teratoma. The lesion was treated with radiation therapy because a surgical approach was rejected. The patient is free of metastatic disease after 28 years evolution of the lesion, retrospectively seen to be present on a conventional radiography performed in 1980. A review of the literature revealed 20 case reports of neuroendocrine tumors arising from the presacral region (with or without associated tailgut cyst or sacrococcygeal teratoma) and sometimes extending to the sacrum. One additional case was located within the neural canal and involved the sacrum, the presacral region, and the rectal wall. Our case is the only tumor arising primarily from the sacrum. The long evolution of this lesion without any other location makes metastatic disease very improbable and this case appears to be a unique example of primary intraosseous sacral carcinoid tumor.

    Formerly named carcinoids, neuroendocrine tumors originate from diffuse endocrine cells, can involve any part of the gastrointestinal tract, endocrine pancreas and bronchopulmonary (BP) tree, and have a wide range of malignant potential. This chapter summarizes the data available on the epidemiology of neuroendocrine neoplasia (NEN) from around the world, including the relative frequency according to organ of origin, annual incidence rates (IR) and trends in IR at the various anatomic sites, age and stage at presentation, racial and gender differences in IR and 5-year survival rates. Over time, changes have been made in the classification and registration of NEN, both in the same registry and across the globe, thus confounding the possibility to draw conclusions as to the true rise in IR of NEN that is observed all over the world. BP NEN has become the most common site in many western countries, while NEN of the rectum is more common in the Far East. In some countries, appendiceal NEN is the most common site in females. When compared to adenocarcinoma of the same location, the prognosis of NEN patients is better. Five-year survival rates are highest for NEN originating in the rectum and appendix, but lower in small intestinal and pancreatic NEN. Future research is needed to understand the contribution of genetic and environmental factors to NEN epidemiology. PMID:26303701

    Purpose. Tailgut cysts with malignant transformation are rare entities. We discuss the diagnostic strategy and treatment of a malignancy within a tailgut cyst. Methods. In this study we report on the case of a 61-year-old man with a malignant neuroendocrine tumour arising within a tailgut cyst and an overview of the literature emphasising the histopathological characteristics and differential diagnosis. Results. Our patient presented with lower back pain, rectal pain, and increased urgency of defecation. MRI scan and CT-guided biopsy on histological analysis revealed a diagnosis of carcinoid tumour of the presacral space. The patient subsequently underwent an abdominoperineal excision of the rectum. Conclusions. This case highlights the importance of tailgut cysts as a differential diagnosis of presacral masses. It is a rare congenital lesion developing from remnants of the embryonic postanal gut and is predominantly benign in nature. Approximately half of cases remain asymptomatic; therefore, diagnosis is often delayed. Magnetic resonance imaging is the investigation of choice and an awareness of the possibility of malignant potential is critical to avoiding missed diagnosis and subsequent morbidity. Complete surgical excision allows accurate diagnosis, confirmation of oncological clearance, and prevention of mortality. PMID:25478281

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.

    Full Text Available Abstract Background Carcinoid heart disease, a known complication of neuroendocrine tumors, is characterized by right heart fibrotic lesions. Carcinoid heart disease has traditionally been defined by the degree of valvular involvement. Right ventricular (RV dysfunction due to mural involvement may also be a manifestation. Connective tissue growth factor (CCN2 is elevated in many fibrotic disorders. Its role in carcinoid heart disease is unknown. We sought to investigate the relationship between plasma CCN2 and valvular and mural involvement in carcinoid heart disease. Methods Echocardiography was performed in 69 patients with neuroendocrine tumors. RV function was assessed using tissue Doppler analysis of myocardial systolic strain. Plasma CCN2 was analyzed using an enzyme-linked immunosorbent assay. Mann-Whitney U, Kruskal-Wallis, Chi-squared and Fisher's exact tests were used to compare groups where appropriate. Linear regression was used to evaluate correlation. Results Mean strain was -21% ± 5. Thirty-three patients had reduced RV function (strain > -20%, mean -16% ± 3. Of these, 8 had no or minimal tricuspid and/or pulmonary regurgitation (TR/PR. Thirty-six patients had normal or mildly reduced RV function (strain ≤ -20%, mean -25% ± 3. There was a significant inverse correlation between RV function and plasma CCN2 levels (r = 0.47, p Conclusions Elevated plasma CCN2 levels are associated with RV dysfunction and valvular regurgitation in NET patients. CCN2 may play a role in neuroendocrine tumor-related cardiac fibrosis and may serve as a marker of its earliest stages.

  18. Bone tumors: Nursing care

    International Nuclear Information System (INIS)

    Bone tumors represent approximately 5% of childhood malignancies. osteosarcoma is the primary malignant bone tumor, accounting for 60% of cancer with peak incidence in the 2nd decade of life. Ewing's sarcoma is the second most common bone cancer with peak at a slightly younger age. This presentation discusses similarities and differences in the diagnosis and treatment of these two malignancies. Diagnostic procedures include plain radiographs, CT and MRI of the primary site, plain x-ray and CT of the chest, bone scan, and biopsy of the primary tumor. For patients diagnosed with Ewing's sarcoma, a bone marrow aspirate and biopsy will also be required. Our current approach to the treatment of bone tumors includes preoperative combination chemotherapy and en bloc surgical removal of the tumor followed by postoperative chemotherapy. In the case of Ewing's sarcoma, radiation therapy may be employed in addition to surgery, if margins are questionable of instead of surgery, if the tumor is not resectable

    Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses. Features of a mature cystic teratoma were seen very focally. Immunohistochemistry revealed strong, diffuse positivity for CD56 and synaptophysin. Chromogranin immunonegativity was noted and there was an absence of nuclear β-catenin accumulation. Ki-67 index was 10-12%. Although there is no established diagnostic framework for primary ovarian carcinoid tumors, this case was diagnosed as a well-differentiated neuroendocrine tumor, Grade 2 (intermediate grade), arising in association with a mature cystic teratoma/dermoid cyst. This case highlights the need to develop ovarian diagnostic criteria in this area. PMID:27508272

  3. Effect of somatostatin analogue 201-995 on blood flow to endocrine tumors

    International Nuclear Information System (INIS)

    The analogue of somatostatin inhibits gastroenteropancreatic tumor hormone secretions and may inhibit tumor growth, but no direct actions have been observed. The authors postulate that the effects of somatostatin are mediated by reducing tumor blood flow. This was evaluated with angiography before and after administration of somatostatin in five patients: two with gastrinomas, one with carcinoid, one with Vipoma, and one with an occult insulinoma. In three patients with hepatic metastases and one with a primary benign intrahepatic gastrinoma, a subcutaneous dose of 100 μg of somatostatin decreased tumor blood flow, an effect observed within 45 minutes and persisting for up to 2 hours. Parallel reductions in hormone secretion, symptoms, and tumor size were observed. The Vipoma infarcted within 3 months of treatment. In contrast, somatostatin had no vascular effects on a primary pancreatic carcinoma. The authors' data suggest that somatostatin may slow the rate of tumor growth or even cause regression by reducing blood flow

    Full Text Available Childhood vitiligo is often encountered in dermatological practice. When present in infancy or early childhood, various nevoid and hereditary disorders are to be differentiated. In many cases, familial aggregation of the disease is seen and other autoimmune disorders may be associated. Segmental presentation is more common, and limited body surface area involvement is usual in this age group. Children with vitiligo often suffer from anxiety and depression because of their unusual appearance. Management of vitiligo in children is difficult as therapeutic options are restricted when compared to that in adult patients. Selection of treatment should be careful in these patients with the aim to achieve best results with minimal side effects as well as relieving patients′ and parents′ anxiety.

    Although the function of zinc finger and BTB domain containing 16 (ZBTB16) in spermatogenesis is well documented, expression of ZBTB16 in germ cell tumors has not yet been studied. The aim of this study was to investigate the immunohistochemical expression and diagnostic utility of ZBTB16 in germ cell tumors. A total of 67 adult germ cell tumors were studied (62 testicular germ cell tumors, 2 ovarian yolk sac tumors, 1 mediastinal yolk sac tumor, and 2 retroperitoneal metastatic yolk sac tumors). The 62 testicular primary germ cell tumors are as follows: 34 pure germ cell tumors (20 seminomas, 8 embryonal carcinomas, 2 teratomas, 1 choriocarcinoma, 1 carcinoid, and 2 spermatocytic tumors) and 28 mixed germ cell tumors (composed of 13 embryonal carcinomas, 15 yolk sac tumors, 15 teratomas, 7 seminomas, and 3 choriocarcinomas in various combinations). Thirty-five cases contained germ cell neoplasia in situ. Yolk sac tumor was consistently reactive for ZBTB16. Among the 15 testicular yolk sac tumors in mixed germ cell tumors, all displayed moderate to diffuse ZBTB16 staining. ZBTB16 reactivity was present regardless of the histologic patterns of yolk sac tumor and ZBTB16 was able to pick up small foci of yolk sac tumor intermixed/embedded in other germ cell tumor subtype elements. Diffuse ZBTB16 immunoreactivity was also observed in 2/2 metastatic yolk sac tumors, 1/1 mediastinal yolk sac tumor, 2/2 ovarian yolk sac tumors, 2/2 spermatocytic tumors, 1/1 carcinoid, and the spermatogonial cells. All the other non-yolk sac germ cell tumors were nonreactive, including seminoma (n=27), embryonal carcinoma (n=21), teratoma (n=17), choriocarcinoma (n=4), and germ cell neoplasia in situ (n=35). The sensitivity and specificity of ZBTB16 in detecting yolk sac tumor among the germ cell tumors was 100% (20/20) and 96% (66/69), respectively. In conclusion, ZBTB16 is a highly sensitive and specific marker for yolk sac tumor. PMID:26916077

    Acute pancreatitis is a rare finding in childhood but probably more common than is generally realized. This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. Patients with hereditary pancreatitis are at high risk for pancreatic cancer.

    One hundred and ten cases of thymic tumors were intervened surgically, including 92 thymoma, 8 thymie earcinoid, and 10 thymic carcinoma. In this series, 50. 9 % of the cases were complicated with various syndromes, 44. 5 % with myasthenia gravis (MG). Resection rate was correlated with the size and invasion of the tumor. There was significant difference in resection rate among thymoma, thymic carcinoid and thymic carcinoma. The degree of invasiorl undoubtely influenced on resection. The 3-, 5- and 10- year suvival rate of the thymoma were 82. 7 %, 68. 1 % and 40. 0 %, respectively. The prognosis depended on the pathoioglcal classification and the severity of the neighbouring invasion, but MG had no sianificant effect on prognosis. Recurrence and metastasis of the tumor were the main cause of late death.

Entre las neoplasias malignas se incluyen el tumor carcinoide bronquial, carcinoma mucoepidermoide, linfoma pulmonar, blastoma pleuropulmonar y las metástasis. El diagnóstico de las neoplasias primarias pulmonares frecuentemente es tardío, por su baja incidencia y la falta de sospecha clínica o por su presentación atípica.

Psoriasis in children has been reported to differ from that among adults being more frequently pruritic; plaque lesions are relatively thinner, softer, and less scaly; face and flexural involvement is common and guttate type is the characteristic presentation. Whether onset in childhood predicts a more severe form of psoriasis is a matter of controversy, it may cause significant morbidity particularly if it keeps relapsing. Most children have mild form of psoriasis which can be generally treated effectively with topical agents such as emollients, coal tar, corticosteroids, dithranol, calcipotriol etc. according to age and the sites affected. Narrow band UVB is the preferred form of phototherapy in children for moderate to severe disease or in patients not responding to topical therapy alone. Systemic therapies are reserved for more severe and extensive cases that cannot be controlled with topical treatment and/or phototherapy such as severe plaque type, unstable forms like erythrodermic and generalized pustular psoriasis and psoriatic arthritis. There are no controlled trials of systemic therapies in this age group, most experience being with retinoids and methotrexate with favorable results. Cyclosporine can be used as a short-term intermittent crisis management drug. There is an early promising experience with the use of biologics (etanercept and infliximab in childhood psoriasis. Systemic treatments as well as phototherapy have limited use in children due to cumulative dose effects of drugs, low acceptance, and risk of gonadal toxicity. More evidence-based data is needed about the effectiveness and long-term safety of topical

    The results of CT in 100 patients with acute hemiplegia in childhood are reported here. The etiology was various: 2 patients had infratentorial brain tumors, 56 had cerebral vascular diseases, 3 had head injuries, 16 had intracranial infectious diseases, one had postinfectious encephalomyelitis, one had multiple sclerosis, 2 had epilepsy, and the diagnosis of 19 were unknown. Eleven patients had a normal CT and a good prognosis. As for the type of onset, there were patients of type 1 with fever and 42 with convulsions and unconsciousness; those of type 2 with convulsions and unconsciousness were 12, and those of type 3 without fever and convulsions were 46. This classification is assumed to be useful, as the type of onset is characteristic of the etiology. Six patients were diagnosed correctly by repeated examinations, although the first CT did not reveal any remarkable findings. Capsular infarction, occlusion of the posterior cerebral artery in acute hemiplegia in childhood, abnormal findings of the internal capsule, thalamus, and midbrain in a patient with postinfectious encephalomyelitis, and a diffuse low density in the CT of the unilateral hemisphere in the patients with acute encephalopathy and acute hemiplegia of an obscure origin have been found after the introduction of computerized tomography.

  16. Successful and unsuccessful approaches to imaging carcinoids: comparison of a radiolabelled tryptophan hydroxylase inhibitor with a tracer of biogenic amine uptake and storage, and a somatostatin analogue

    International Nuclear Information System (INIS)

    A mouse mastocytoma model was used to determine the biodistribution and tumour uptake of four radiopharmaceuticals developed to target the serotonin synthetic pathway in carcinoid tumours. Three of the compounds were competitive inhibitors of the rate-limiting enzyme of serotonin synthesis, tryptophan hydroxylase. Radiolabelled iodo-DL-phenylalanine (iodine-131 PIPA) was found to have the highest uptake and tumour-to-liver ratio. Four patients with known carcinoid tumours were then injected with 0.5 mCi 131I-PIPA and imaged at 1, 4, 24 and 48 h post-injection. The radiopharmaceutical, however, failed to localize in the known tumour sites. This result was in contrast to the authors' experience of 131I- and 123I-MIBG imaging of carcinoid tumours. Seven patients with known metastatic carcinoid tumours, two patients with symptoms of recurrence following tumour resection, one patient with completely resected disease, and two patients with a flushing syndrome of uncertain aetiology were studied with 131I-MIBG. Three of the seven patients with known metastatic disease had positive 131I-MIBG scans. Both patients with clinical evidence of recurrent disease had negative scans, as did the patient who was considered to have had complete resection of her primary tumour. The two patients with idiopathic flushing syndrome also had negative scans. Among seven patients imaged with 123I-MIBG there were four true-negative scans and one false-negative, the latter in a patient with biochemical and CT evidence of recurrence. In a seventh patient with distant metastases there was variable uptake in some of the lesions. Four patients were studied with indium-111 pentetreotide. Two patients with metastatic carcinoid disease had positive scans, although hepatic metastases were not seen in one. Another two with idiopathic flushing syndrome had normal studies. (orig./MG)

    Full Text Available Central nervous system tumors are the second most common type of childhood cancer in Turkey. Germinomas constitute two thirds of intracranial germ cell tumors. The granulomatous inflammation occurring around germinomas can cause histological diagnostic difficulty. We present a 12-year-old girl with a diagnosis of germinoma in the corpus callosum associated with granulomatous reaction to emphasize the diagnostic challenge which may occur during stereotactic biopsy interpretation or intraoperative consultation.

  18. Endocrine tumor of the digestive tract - clinical case study

    International Nuclear Information System (INIS)

    Introduction: Endocrine tumors of the digestive tract (ETDT) are neoplasms which stem from the APUD (amine precursors uptake and decarboxylation) cells. There are neuroendocrine pancreatic and gastroenteral carcinoid tumors which stand for 2% of digestive tract tumors, 0,5% of all human malignant neoplasms. All of them have secretion granulations in the cytoplasm. That is why a number of immune histochemic techniques is used in search for biogenic amines and hormones such as gastrin, CCK, GIP, VIP, motilin, glucagon, GRP, PP, GHRH and the others. In the majority of cases neuroendocrine tumors of the rectum are described as dysfunctional, which means that specific clinical symptoms are not connected with their hormonal overproduction. Material and methods: We describe a case of fifty seven years old male patient admitted to the Department of General and Transplant Surgery for the diagnosis and treatment of the rectal tumor. Per rectum examination revealed hard tumor. The pathologic examination of the biopsy taken from the lesion and CT scanning confirmed the presence of endocrine tumor of the digestive tract. Results: Anterior resection of the rectum was performed, the postoperative course was uneventful. At present patient is subjected to complementary treatment with the use of somatostatin analogue of the prolonged action. Conclusion: The endocrine tumors of the rectum are extremely rare, they occur in this localization in 0,26-0,52 out of 100.000 all rectal tumors. Diagnosis is usually made upon the microscopic examination and the immune histochemic reactions. (author)

    1999-11-01

    Psoriasis is a common skin disease in infants, children, and adolescents. A review of the clinical, epidemiologic, genetic, and therapeutic aspects of childhood psoriasis is presented. Population studies indicate that the first signs of psoriatic lesions occur in the pediatric age group, birth to 18 years of age, and that both genetic and environmental factors interact to precipitate the development of psoriasis. Koebner reactions are the result of external or internal triggering factors, such as physical injury to the skin, low humidity, and certain drugs. The most frequently observed variant to psoriasis is the plaque type, followed by guttate psoriasis, and juvenile psoriatic arthritis. Pustular psoriasis and erythrodermic psoriasis are rare forms of the disease, but are seen in children from infancy to adolescence. The scalp is the most frequently affected site of involvement in pediatric psoriasis, followed by the appearance of lesions on the extensor surfaces of the extremities, trunk, and nails. Although not common in adult psoriasis, the face and ears are often involved. Topical medications such as corticosteroids, calcipotriol, coal tar preparations, anthralin formulations, and ultraviolet B are recommended in monotherapy or in combination therapy, whereas psoralen plus ultraviolet A, methotrexate, and retinoids should only be administered in crisis situations. The treatment objectives in childhood psoriasis are to preserve skin surfaces, to afford physical relief from the disease, and to employ treatments that do not endanger the health or future development of the child.

    Many childhood cancer survivors have psychosocial late effects. We studied the risks for cohabitation and subsequent separation. Through the Danish Cancer Register, we identified a nationwide, population-based cohort of all 1877 childhood cancer survivors born from 1965 to 1980, and in whom cancer was diagnosed between 1965 and 1996 before they were 20 years of age. A sex-matched and age-matched population-based control cohort was used for comparison (n=45,449). Demographic and socioeconomic data were obtained from national registers and explored by discrete-time Cox regression analyses. Childhood cancer survivors had a reduced rate of cohabitation [rate ratio (RR) 0.78; 95% confidence interval (CI): 0.73-0.83], owing to lower rates among survivors of both noncentral nervous system (CNS) tumors (RR 0.88; 95% CI: 0.83-0.95) and CNS tumors (RR 0.52; 95% CI: 0.45-0.59). Male CNS tumor survivors had a nonsignificantly lower rate (RR 0.47; 95% CI: 0.38-0.58) than females (RR 0.56; 95% CI: 0.47-0.68). The rates of separation were almost identical to those of controls. In conclusion, the rate of cohabitation was lower for all childhood cancer survivors than for the population-based controls, with the most pronounced reduction among survivors of CNS tumors. Mental deficits after cranial irradiation are likely to be the major risk factor.

    Full Text Available Intracranial tumors are the second cause of malignancies in childhood following leukemia. The overall incidence varies between 1:20000 and 1:100000 in different series. They are the most common solid tumors that occur in childhood .The most important diagnostic feature of an intracranial mass is its location. They can be supratentorial or infratentorial. With the exception of the first year of life, infratentorial brain tumors are more frequent than supratentorial tumors in the first decade of life. In particular, these are cerebellar low-grade astrocytomas, medulloblastomas, brain stem gliomas and ependymomas of the fourth ventricle. .Posterior fossa tumors also are readily identified with both CT and MRI. Spectroscopy in the analysis of brain tumors has recently come on the scene but may be of limited practical value when it comes to differentiating tumors. However, CT and especially MRI are the primary imaging modalities for the investigation of brain tumors. Sonography can be used in the neonates. With modern imaging, it is relatively easy to detect the presence of a tumor in most patients. The purpose of this essay is to illustrate the imaging features of various infratentorial brain tumors to make a clue for differentiation them by these features.

    Full Text Available Abstract Background The aim was to investigate HRQoL and psychosocial function among patients with carcinoid tumours, longitudinally and prospectively, and to compare HRQoL among patients with carcinoid tumours to that of the Swedish general population. The aim was also to investigate the prevalence of distress during the first year after diagnosis. Methods At four assessments during the first year after diagnosis, HRQoL was measured by the EORTC QLQ-C30 3.0, anxiety and depression by the HADS, and prevalence, and worst aspects of distress by an interview guide. ANOVA was performed in order to study changes over time with regard to HRQoL, anxiety and depression. Comparisons regarding HRQoL between patients and the Swedish population were made by the use of one-sample t-tests and changes over time regarding the prevalence of distress was investigated by means of Cochran's Q. Results High levels of physical-, emotional-, cognitive-, and social function and somewhat lower levels of role function and global quality of life were reported at all assessments. Role- and emotional function increased over time. Patients reported lower role function and global quality of life and more problems with fatigue and diarrhoea than the Swedish general population, at all assessments. Fatigue, limitations to work and pursue daily activities, and worry that the illness will get worse were among the most prevalent aspects at all assessments. At all assessments the majority reported worrying about the family's situation, the ability to care for the family, and worrying before the check-up. Conclusion It is concluded that HRQoL and psychosocial function among patients with carcinoid tumours remains stable during the first year, that the patients report a lower HRQoL than the Swedish general population, and that a majority of the patients report a number of aspects of emotional distress. In the clinical care, it should be considered that the majority of patients report

    1990-01-01

    The distribution of the proopiomelanocortin-derivated amidated joining peptide (JP-N) was examined in the human pituitary gland, adrenal gland, gut and in three bronchial carcinoids. Double immunostaining showed coexistence of immunoreactive JP-N and other proopiomelanocortin derivatives, e......-N was costored with somatostatin in endocrine cells. Using radioimmunoassay, JP-N was found in higher concentrations than ACTH and alpha-MSH in the gut but not in the adrenal gland. Gel chromatography of gastric antrum and adrenal gland extracts showed three and two dominating components of immunoreactive JP......-N, respectively, but under reduced conditions most of the immunoreactive material appeared as of low molecular weight in both extracts. In conclusion, immunoreactive JP-N is a major product from the processing of proopiomelanocortin in human extrapituitary tissues. The molecular forms of immunoreactive JP...

  7. Somatostatin receptor scintigraphy. A new imaging method for the specific identification of carcinoids of the small intestine

    International Nuclear Information System (INIS)

    Scintigraphy with a radiolabelled somatostatin analog represents a new highly specific approach in the diagnostic work-up of receptor-positive APUD tumours and their metastases. We present our preliminary results with somatostatin receptor scintigraphy in 15 patients with histologically proven midgut-carcinoid. 5 out of 6 primary tumour sites (83%) and 90% of the known metastatic lesions could be detected; unknown metastatic lesions were seen in 5 patients. Compared with other nuclear medicine procedures somatostatin receptor scintigraphy is able to detect all tumour sites within hours. This advantage will promote the acceptance of this sensitive and specific imaging modality by the clinicians with regard to preoperative work-up and symptomatic therapy with a somatostatin analog.

    Medulloblastoma accounts for 15-20% of childhood nervous system tumours. The risk of dying was reduced by 30% in the last twenty years. Patients are divided in risk strata according to post-surgical disease, dissemination, histology and some molecular features such as WNT subgroup and MYC status. Sixty to 70% of patients older than 3 years are assigned to the average-risk group. High-risk patients include those with disseminated and/or residual disease, large cell and/or anaplastic histotypes, MYC genes amplification. Current and currently planned clinical trials will: (1) evaluate the feasibility of reducing both the dose of craniospinal irradiation and the volume of the posterior fossa radiotherapy (RT) for those patients at low biologic risk, commonly identified as those having a medulloblastoma of the WNT subgroup; (2) determine whether intensification of chemotherapy (CT) or irradiation can improve outcome in patients with high-risk disease; (3) find target therapies allowing tailored therapies especially for relapsing patients and those with higher biological risk.

    Full Text Available Jaume Mora1,21Department of Oncology, 2Developmental Tumor Biology Laboratory, Hospital Sant Joan de Deu, Fundacio Sant Joan de Deu, Barcelona, SpainAbstract: Working together with medical oncologists, the question of whether a Ewing sarcoma in a 25-year-old is a pediatric tumor comes up repeatedly. Like Ewing's, some tumors present characteristically at ages that cross over what has been set as the definition of pediatrics (15 years, 18 years, or 21 years?. Pediatric oncology textbooks, surprisingly, do not address the subject of defining a pediatric tumor. They all begin with an epidemiology chapter defining the types of tumors appearing at distinct stages of childhood, adolescence, and young adulthood. Describing the epidemiology of tumors in relation to age, it becomes clear that the disease is related to the phenomenon of aging. The question, however, remains: is there a biological definition of what pediatric age is? And if so, will tumors occurring during this period of life have anything to do with such biological definition? With the aim of finding an objective definition, the fundamental concepts of what defines "pediatrics" was reviewed and then the major features of tumors arising during development were analyzed. The tumors were explored from the perspective of a host immersed in the normal process of growth and development. This physiological process, from pluripotential and undifferentiated cells, makes possible the differentiation, maturation, organization, and function of tissues, organs, and apparatus. A biological definition of pediatric tumors and the infancy–childhood–puberty classification of developmental tumors according to the infancy–childhood–puberty model of normal human development are proposed.Keywords: growth and development, pediatric tumor, infant, childhood and adolescence, pubertal tumors

    2016-01-01

    Objectives Pulmonary carcinoid (PC) is a rare tumour with good prognosis following surgical resection. However, little is known regarding patient characteristics and use of other treatments modalities. Our objective was to review patient characteristics, treatment and survival for patients with PC and contrast these results with other forms of non-small cell lung cancer (NSCLC). Setting Audit data from UK National Lung Cancer Audit (NLCA) 2008–2013. Participants 184 906 lung cancer cases were submitted to the NLCA. Outcome measures Primary outcome—survival rates between PC and NSCLC. Secondary outcome—differences in performance status, lung function and treatment modality between PC and NSCLC. Results PC histology was recorded in 1341 (0.73%) patients and non-carcinoid NSCLC histology in 162 959 (87.4%) cases. 91% of patients with PC had good performance status (Eastern Cooperative Oncology Group (ECOG) 0–1), compared with only 53% of NSCLC. 66% of PC had localised disease. Of all PC cases, 77% were treated with surgery, 6.2% received chemotherapy and 3.6% received radiotherapy, with the remainder treated with best supportive care. Overall 1-year and 3-year survival rates for PC were 92% and 84.7%, respectively. In contrast, 1-year and 3-year survival rates for NSCLC were 36.2% and 15.6%, However, 3-year survival for PC markedly decreased with worsening performance status and advanced disease to 23.8% for performance status ECOG 3–4 and 33.6% for stage IV disease. Conclusions In contrast to other forms of NSCLC, the majority of patients with PC present with good performance status, preserved lung function and early stage disease amenable to surgical resection. However, 1 in 5 patients with PC has metastatic disease which is associated with poor prognosis, as is poor performance status at presentation. We believe these data will help clinicians provide accurate prognostic predictions stratified according to patient characteristics at presentation, as

  8. Brachytherapy in childhood rhabdomyosarcoma treatment

    International Nuclear Information System (INIS)

    A retrospective study of 21 children with rhabdomyosarcoma treated by brachytherapy to the primary site of the tumor at the Radiotherapy Department of the A.C.Camargo Hospital between january/1980 to june/1993 was undertaken. The main objectives were to comprove the utility of brachytherapy in childhood rhabdomyosarcoma, to evaluate the local control and survival, in association with chemotherapy, to analyze the late effects of the treatment and to determinate the preferential technique to each clinical situation. All patients received brachytherapy to the tumor site. The radioactive isotopes employed were Gold198, Cesium137 and Iridium192. The brachytherapy techniques depended on the tumor site, period of treatment, availability of the radioactive material and stage of the disease. Patients treated exclusively by brachytherapy received 40 Gy to 60 Gy. When brachytherapy was associated with external radiotherapy the dose ranged from 20 Gy to 40 Gy. Local control was achieved in 18 of 20 patients (90%). The global survival and local control survival rates were 61.9% (13/21 patients) and 72,2% (13/18 patients) respectively. (author)

    Neoplasms of the appendix are rare, but because of their unusual presentation and unpredictable biologic behavior, it is important to diagnose them correctly. Mucinous tumors account for 58 % of malignant tumors of appendix in SEER database and the remaining are carcinoids. The mucinous appendiceal tumors have a potential to spread to the peritoneum and viscera in the form of gelatinous material with or without neoplastic cells resulting in Pseudomyxoma peritonei. (PMP) PMP is a clinical entity that has a unique biological behavior and can arise from seemingly benign tumors to frankly malignant ones. Several classifications exist for PMP of which Ronnet's classification has been the most popular. In 2010, the WHO proposed a 2 tier classification that classified PMP as either low grade or high grade based on the presence of mucin, cytological and architectural features. According to this classification when the underlying cause for PMP is an appendiceal tumor it is always a mucinous adenocarcinoma rather than a mucocoele or adenoma and these terms should no longer be used. This system of classification helps in predicting the behavior of the tumor and proper treatment strategies. The understanding of the pathogenesis of the disease has also improved with identification of newer biomarkers and molecular genetic alterations. IHC markers CK 20, CDX2 and MUC2 are found to be positive in these tumors in addition to KRAS mutation and loss of heterozygosity in some gene loci. Proper histopathologic classification and predicting the tumor behavior requires a close interaction between the pathologist and the surgeon. The use of the combined modality treatment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has led to a 5-year survival ranging from 62.5 % to 100 % for low grade, and 0 %-65 % for high grade disease. This article focuses on the etiopathogenesis, clinical behavior, diagnosis and classification of mucinous tumors of the

  11. Malignant renal tumors in pediatrics

    International Nuclear Information System (INIS)

    Introduction: Professionals who work in pediatric oncology, we see childhood cancer as a common disease, but in fact constitutes about 2% of all cancers diagnosed worldwide. Wilms tumor accounts for 6% of all childhood tumors and presentation bilateral accounts for 4-6% of all Wilms tumors diagnosed. Theoretical Framework: In the period between the year 1994-2003 period were attended in the Pediatric Hematology-Oncology Center, a total of 29 cases of malignant renal tumors, corresponding to 86% (25 cases) to Wilms tumor or nephroblastoma tumor. The Wilms is of embryonic origin, capable of metastatic spread, (85% lungs 15% liver). Very sensitive to chemotherapy and radiotherapy, which confers high cure rates (85%); having a multidisciplinary treatment model, combining surgery, chemotherapy, and radiotherapy. The role of nursing in comprehensive cancer care child is essential in the prevention and early detection of side effects or complications. Case report: S.D. currently 10 years old. In 10/1994, at 8 months of age, was diagnosed with bilateral Wilms tumor. On admission her weight was 8200gr with abdominal circumference 50cm. Conducted pre-operative MDT and 02/1995 nephrectomy of the left kidney and right kidney lumpectomy (tumor nodule 420gr. and a 250gr.). MDT begins in 03/1995 01/1996 ending. 09/2003 with abdominal pain and vomiting, and kidney failure. 10/2003 lumpectomy biopsy (sclerotic nodule associated with maturation nephroblastoma). Currently severe renal insufficiency plan enters dialysis. Nursing process: Objectives: 1) To prepare the child and family to the side effects and possible complications of chemotherapy and / or radiotherapy 2) Prevent and minimize related complications tumor and / or treatment. Care Plan comprises four stages: A) rating and customer income. B) Implement care chemotherapy C) post-operative Care D) Implement radiation care

  14. Clinic, diagnosis and therapy of tumors of the small intestine

    International Nuclear Information System (INIS)

    53 cases of tumor of the small intestine were observed, of which 23 were benign, 14 carcinomas, 10 sarcomas, 6 carcinoid tumors. The age ranged from 1 to 81 years; an incidence peak was found between 51 and 60. The ratio of male and female patients was 3 : 2. Almost all patients with malignoma came to our hospital only in an already advanced stage, 65% of the malignant tumors had already developed metastases. Preoperative diagnostics was significantly improved during the last years. Since 1972, i.e. since hypotonous duodenography, double contrast technique and endoscopy are applied, accuracy of the diagnostic methods could be increased by more than 100%. But due to the fact that these improved techniques were applied too late because of atypical symptoms and signs, prognosis of malignomas of the small intestine has been bad also in the last years. 16% of the patients died of postoperative complications and the 5-year survival rate was only 18%. From this results that prognosis cannot be improved even by applying the modern diagnostic methods, because malignant tumors of the small intestine provoke pain almost exclusively in advanced stages. There don't exist typical early symptoms or signs. (orig./ARB)

    Full Text Available Abstract Introduction Autopsy series have shown that metastasis to the thyroid gland has occurred in up to 24% of patients who have died of cancer. Neuroendocrine tumors may metastasize to thyroid gland. Case presentations Case 1 was a 17-year-old Turkish woman who was referred from our Endocrinology Department for a thyroidectomy for treatment of neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination results were consistent with a neuroendocrine tumor; neoplastic cells showed strong immunoreactivity to chromogranin A and synaptophysin, but the immunohistochemical profile was inconsistent with medullary thyroid carcinoma in that the tumor was negative for calcitonin, carcinoembryonic antigen, and thyroid transcription factor-1. Case 2 was a 54-year-old Turkish woman who presented with a 3-cm nodule on her right thyroid lobe. She had undergone surgery for a right lung mass four years previously. After a right pneumonectomy, thymectomy and lymph node dissection, a typical carcinoid tumor was diagnosed. Under ultrasonographic guidance, fine needle aspiration biopsy of her right thyroid pole nodule was performed and the biopsy was compatible with a neuroendocrine tumor metastasis. She was treated with a bilateral total thyroidectomy. Histopathological examination indicated three nodular lesions, 5 cm and 0.4 cm in diameter in her right lobe and 0.1 cm in diameter in her left lobe. The tumors were consistent with a neuroendocrine phenotype, showing strong immunoreactivity to chromogranin A and synaptophysin. Conclusion Thyroid nodules detected during follow-up of neuroendocrine tumor patients should be thoroughly investigated. A fine needle aspiration biopsy of the thyroid confirms the diagnosis in most cases and leads to appropriate management of those patients and may prevent unnecessary treatment approaches.

    Full Text Available The mTOR inhibitor everolimus has shown promising results in some but not all neuroendocrine tumors. Therefore, early assessment of treatment response would be beneficial. In this study, we investigated the in vivo and in vitro treatment effect of everolimus in neuroendocrine tumors and evaluated the performance of 18F-FDG and the proliferation tracer 18F-FLT for treatment response assessment by PET imaging.The effect of everolimus on the human carcinoid cell line H727 was examined in vitro with the MTT assay and in vivo on H727 xenograft tumors. The mice were scanned at baseline with 18F-FDG or 18F-FLT and then treated with either placebo or everolimus (5 mg/kg daily for 10 days. PET/CT scans were repeated at day 1,3 and 10.Everolimus showed significant inhibition of H727 cell proliferation in vitro at concentrations above 1 nM. In vivo tumor volumes measured relative to baseline were significantly lower in the everolimus group compared to the control group at day 3 (126±6% vs. 152±6%; p = 0.016, day 7 (164±7% vs. 226±13%; p<0.001 and at day 10 (194±10% vs. 281±18%; p<0.001. Uptake of 18F-FDG and 18F-FLT showed little differences between control and treatment groups, but individual mean uptake of 18F-FDG at day 3 correlated with tumor growth day 10 (r2 = 0.45; P = 0.034, 18F-FLT mean uptake at day 1 correlated with tumor growth day 7 (r2 = 0.63; P = 0.019 and at day 3 18F-FLT correlated with tumor growth day 7 (r2 = 0.87; P<0.001 and day 10 (r2 = 0.58; P = 0.027.Everolimus was effective in vitro and in vivo in human xenografts lung carcinoid NETs and especially early 18F-FLT uptake predicted subsequent tumor growth. We suggest that 18F-FLT PET can be used for tailoring therapy for neuroendocrine tumor patients through early identification of responders and non-responders.

    Methods: Systemic irradiation of neuroaxis is an essential part in the management of medulloblastoma, stPNET and intracranial germ cell tumors. The introduction of quality assurance programs in radiooncology assures a precise radiotherapy of target volumes and is a prerequisite to improve survival. Results: Hyperfractionated radiotherapy has the potential of increasing dose to tumor more safely without increasing the risk for late adverse effects. Pilot studies revealed excellent tumor control in medulloblastoma with acceptable acute toxicity and a long-term survival of up to 96%. In medulloblastoma stereotactic radiation techniques reveal an acceptable toxicity and promising results in tumor control in recurrent disease or as primary treatment. They are now part of future treatment protocols in case of persisting residual tumor. Radiotherapy alone in pure germinoma is continuously yielding high cure rates. In secreting germ cell tumors cisplatin containing chemotherapies in conjunction with radiotherapy achieve a long-term survival rate of 80% today. Especially in high risk medulloblastoma and secreting germ cell tumors chemotherapies are playing an increasingly important role in the interdisciplinary management. It can be expected that future developments of chemotherapeutic protocols and the introduction of new cytostatic substances will further improve the therapeutic outcome. (orig.)

    Introduction Little is known about the impact of childhood cancer on the personal income of survivors. We compared income between survivors and siblings, and determined factors associated with income. Methods As part of the Swiss Childhood Cancer Survivor Study (SCCSS), a questionnaire was sent to survivors, aged ≥18 years, registered in the Swiss Childhood Cancer Registry (SCCR), diagnosed at age 4’500 CHF), even after we adjusted for socio-demographic and educational factors (OR = 0.46, p<0.001). Older age, male sex, personal and parental education, and number of working hours were associated with high income. Survivors of leukemia (OR = 0.40, p<0.001), lymphoma (OR = 0.63, p = 0.040), CNS tumors (OR = 0.22, p<0.001), bone tumors (OR = 0.24, p = 0.003) had a lower income than siblings. Survivors who had cranial irradiation, had a lower income than survivors who had no cranial irradiation (OR = 0.48, p = 0.006). Discussion Even after adjusting for socio-demographic characteristics, education and working hours, survivors of various diagnostic groups have lower incomes than siblings. Further research needs to identify the underlying causes. PMID:27213682

    BACKGROUND: Tumor recurrence is the main cause of death for children with medulloblastoma, the most common malignant childhood brain tumor. The MYCN oncogene is a poor prognosis marker and is amplified in the molecularly defined SHH and Group 4 subgroups but rarely in WNT and Group 3 subgroups of human medulloblastoma. Recent findings on childhood brain tumor relapse mechanisms suggest spatiotemporal differences within these four subgroups. SOX9 is a transcription factor that is important for...

    Carcinoid tumors are rare neuroendocrine tumors (NETs) that are increasing in incidence. Mutation and altered expression of Wnt/β-catenin signaling components have been described in many tumors but have not been well-studied in NETs. Here, we observed accumulation of β-catenin in the cytoplasm and/or nucleus in 25% of clinical NET tissues. By mutational analysis, the mutations of β-catenin (I35S) and APC (E1317Q, T1493T) were identified in NET cells and the tissues. Expression of representative Wnt inhibitors was absent or markedly decreased in BON, a human pancreatic carcinoid cell line; treatment with 5-aza-2'-deoxycytidine (5-aza-CdR) increased expression levels of the Wnt inhibitors. Methylation analyses demonstrated that CpG islands of SFRP-1 and Axin-2 were methylated, whereas the promoters of DKK-1, DKK-3 and WIF-1 were unmethylated in four NET cells. Aberrant methylation of SFRP-1 was particularly observed in most of clinical NET tissues. In addition, the repression of these unmethylated genes was associated with histone H3 lysine 9 dimethylation (H3K9me2) in BON cells. Together, 5-aza-CdR treatment inhibited cell proliferation and decreased the protein levels of H3K9me2 and G9a. Moreover, a novel G9a inhibitor, UNC0638, suppressed BON cell proliferation through inhibition of Wnt/β-catenin pathway. Overexpression of the inhibitory genes, particularly SFRP-1 and WIF-1 in BON cells, resulted in suppression of anchorage-independent growth and inhibition of tumor growth in mice. Our findings suggest that aberrant Wnt/β-catenin signaling, through either mutations or epigenetic silencing of Wnt antagonists, contributes to the pathogenesis and growth of NETs and have important clinical implications for the prognosis and treatment of NETs.

MATERIAIS E MÉTODOS: Exames de 22 pacientes (12 homens, idade média de 60 anos avaliados nos últimos cinco anos em nosso serviço, com confirmação histopatológica, foram retrospectivamente revistos por dois médicos radiologistas e os achados foram descritos em consenso, focando as alterações tomográficas. RESULTADOS: Descrevemos 5 carcinoides típicos, 3 carcinoides atípicos, 3 carcinomas neuroendócrinos de grandes células (CNGCs e 11 cânceres pulmonares de pequenas células (CPPCs. Apenas um carcinoide típico apresentou aspecto característico de nódulo endobrônquico central com atelectasia pulmonar distal, enquanto os demais foram nódulos ou massas pulmonares. Os carcinoides atípicos eram massas pulmonares periféricas e heterogêneas. Um CNGC era massa periférica delimitada e homogênea, enquanto os demais eram mal delimitados e heterogêneos. Os 11 CPPCs eram massas centrais, infiltrativas e heterogêneas, com alterações pleuropulmonares secundárias. Calcificações estavam ausentes nos CNGCs e CPPCs. Metástases foram vistas inicialmente ou no seguimento de todos os CNGCs e CPPCs. CONCLUSÃO: Apesar de alguns aspectos semelhantes nos exames de imagem, os achados radiológicos, quando integrados às informações clínicas, podem constituir critérios importantes na diferenciação dos tipos histológicos de TNPs.

    Full Text Available Well-to-moderately differentiated neuroendocrine tumors of gastroesophageal and pancreatic origin (GEP-NETs with liver metastasis are a heterogeneous group of malignancies for which a range of therapeutic options have been employed. Surgical resection of hepatic metastases or hepatic artery embolization may be beneficial in patients with hepatic-predominant metastatic disease. Patients with “carcinoid” syndrome and syndromes associated with functional pancreatic NET (PNET can be effectively treated with somatostatin analogs. On the other hand, the efficacy of systemic chemotherapy for these patients is limited. A placebo-controlled, double-blind, prospective, and randomized study showed that octreotide LAR improves progression-free survival in patients with advanced midgut functional “carcinoids.” In patients with advanced pancreatic NET, randomized, placebo-controlled studies have recently demonstrated that treatment with the tyrosine kinase inhibitor sunitinib or with mTOR inhibitor everolimus is associated with improved progression-free survival. Based on these studies, octreotide LAR, sunitinib, or everolimus are now considered as first-line therapeutic options in patients with advanced NET. Future studies will likely further define the role of these agents in patients with carcinoid liver metastasis and pancreatic NET liver metastasis.

  7. Tumor vaccines

    International Nuclear Information System (INIS)

    Tumor vaccines have several potential advantages over standard anticancer regiments. They represent highly specific anticancer therapy. Inducing tumor-specific memory T-lymphocytes, they have potential for long-lived antitumor effects. However, clinical trials, in which cancer patients were vaccinated with tumor vaccines, have been so far mainly disappointing. There are many reasons for the inefficiency of tumor vaccines. Most cancer antigens are normal self-molecules to which immune tolerance exists. That is why the population of tumor-specific lymphocytes is represented by a small number of low-affinity T-lymphocytes that induce weak antitumor immune response. Simultaneously, tumors evolve many mechanisms to actively evade immune system, what makes them poorly immunogenic or even tolerogenic. Novel immunotherapeutic strategies are directed toward breaking immune tolerance to tumor antigens, enhancing immunogenicity of tumor vaccines and overcoming mechanisms of tumor escape. There are several approaches, unfortunately, all of them still far away from an ideal tumor vaccine that would reject a tumor. Difficulties in the activation of antitumor immune response by tumor vaccines have led to the development of alternative immunotherapeutic strategies that directly focus on effector mechanisms of immune system (adoptive tumor- specific T-lymphocyte transfer and tumor specific monoclonal antibodies).

    The term "hemangioma" refers to the common tumor of infancy that exhibits rapid postnatal growth and slow regression during childhood. It may cause confusion with venous malformations that are often incorrectly called "cavernous hemangioma". Venous malformations comprise abnormally formed channels that are lined by quiescent endothelium. Accurate diagnosis is required for selecting the appropriate treatment.

    Full Text Available This work is aimed at identifying factors associated with primary jejunum-ileal tumors malignancy, defining a prediction model with sensitivity, specificity and accuracy to distinguish malign from benign neoplasms. These tumors are rare, have highly unspecific presentation and, frequently, are diagnosed late. We reviewed the charts of 42 patients with primary jejunum-ileal tumors treated in the Department of General Surgery of Rio de Janeiro State University Hospital, Rio de Janeiro, RJ, Brazil, from 1969 to 1998. We performed bivariate analyses, based on chi² test, searching associations between tumors malignancy and demographic and clinical variables. Then logistic regression was employed to consider the independent effect of variables previously identified on malignancy risk. The malign tumors included 11 adenocarcinomas, 7 leiomyosarcomas, 5 carcinoids and 4 lymphomas; the benign tumors included 10 leiomyomas, 2 hamartomas, and single cases of adenoma, multiple neurilemoma and choristoma. The bivariate analyses indicated the association between malignancy and palpable abdominal mass (P = 0.003, period from signs and symptoms onset to diagnosis (P = 0.016, anemia (P = 0.020, anorexia (P = 0.003, abdominal pain (P = 0.031, weight loss (P = 0.001, nausea and vomit (P = 0.094, and intestinal obstruction (P = 0.066; no association with patients demographic characteristics were found. In the final logistic regression model, weight loss, anemia and intestinal obstruction were statistically associated with the dependent variable of interest. Based only on three variables -- weight loss, anemia and intestinal obstruction -- the model defined was able to predict primary jejunum-ileal tumors malignancy with sensitivity of 85.2%, specificity of 80.0%, and accuracy of 83.3%.

    Gastro-entero-pancreatic (GEP) neuroendocrine tumors (NETs) are rare neoplasms,although their prevalence has increased substantially over the past three decades.Moreover,there has been an increased clinical recognition and characterization of these neoplasms.They show extremely variable biological behavior and clinical course.Most NETs have endocrine function and secrete peptides and neuroamines that cause distinct clinical syndromes,including carcinoid syndrome; however,many are clinically silent until late presentation with mass effects.Investigation and management should be individualized for each patient,taking into account the likely natural history of the tumor and general health of the patient.Management strategies include surgery for cure or palliation,and a variety of other cytoreductive techniques,and medical treatment including chemotherapy,and biotherapy to control symptoms due to hormone release and tumor growth,with somatostatin analogues (SSAs) and alphainterferon.New biological agents and somatostatintagged radionuclides are under investigation.Advances in the therapy and development of centers of excellence which coordinate multicenter studies,are needed to improve diagnosis,treatment and therefore survival of patients with GEP NETs.(C)2008 The WIG Press.All rights reserved.

    Full Text Available How to Cite this Article: Tabatabaei SM, Seddighi A, Seddighi AS. Posterior Fossa Tumor in Children. Iran. J. Child. Neurol 2012;6(2: 19-24. Objective Primary brain tumors are the most common solid neoplasms of childhood, representing 20% of all pediatric tumors. The best current estimates place the incidence between 2.76 and 4.28/100,000 children per year. Compared with brain tumors in adults, a much higher percentage of pediatric brain tumors arise in the posterior fossa. Infratentorial tumors comprise as many as two thirds of all pediatric brain tumors in some large series. Tumor types that most often occur in the posterior fossa include medulloblastoma, ependymoma, cerebellar astrocytoma and brainstem glioma. Materials & Methods All pediatric cases of posterior fossa tumor that were considered for surgery from 1981 to 2011 were selected and the demographic data including age, gender and tumor characteristics along with the location and pathological diagnosis were recorded. The surgical outcomes were assessed according to pathological diagnosis. Results Our series consisted of 84 patients (52 males, 32 females. Cerebellar symptoms were the most common cause of presentation (80.9% followed by headache (73.8% and vomiting (38.1%. The most common histology was medulloblastoma (42.8% followed by cerebellar astrocytoma (28.6%, ependymoma (14.3%, brainstem glioma (7.2% and miscellaneous pathologies (e.g., dermoid,  andtuberculoma (7.2%. Conclusion The diagnosis of brain tumors in the general pediatric population remains challenging. Most symptomatic children require several visits to a physician before the correct diagnosis is made. These patients are often misdiagnosed for gastrointestinal disorders. Greater understanding of the clinical presentation of these tumors and judicious use of modern neuroimaging techniques should lead to more efficacious therapies.References 1.

    Full Text Available We characterized the molecular genetic consequences of a balanced chromosome translocation t(8;22(p21; q12, which occurred as the sole cytogenetic aberration in short-term cultured cells from an intrathoracic mature teratoma in a 15-year-old girl. Fluorescence in situ hybridization and reverse transcription- polymerase chain reaction disclosed that t(8;22 resulted in the fusion of the genes PPP2R2A and CHEK2, with an inserted fragment belonging to class I endogenous retrovirus-related sequences at the junction. Sequencing of the two genes did not reveal any additional mutation. None of the three detected PPP2R2A/CHEK2 fusion transcripts resulted in an in-frame PPP2R2A/CHEK2 chimerical open reading frame; however, in all of them, the known open reading frame of CHEK2 was preserved. Thus, promoter swapping leading to deregulated CHEK2 expression would be the most likely oncogenic mechanism. Whereas inactivating mutations of CHEK2 previously have been described in a variety of sporadic tumors and in inherited cancer-predisposing syndromes, PPP2R2A, encoding a regulatory subunit of the multimeric enzyme phosphatase 2, has not been directly implicated in tumorigenesis. Our findings suggest that deregulation of CHEK2 and/or PPP2R2A is of pathogenetic importance in at least a subset of germ cell tumors.

    Melanotic neuroectodermal tumor of infancy (MNTI) is a rare pigmented craniofacial tumor of newborns and infants. We report the imaging findings of a 3-month old male patient with a maxillary MNTI. Detailed discussion on imaging features on various magnetic resonance sequences and CT scan are included. Characteristic radiographic appearance is also described. MNTI, of neural crest origin, display a biphasic population of melanin containing cells and neuroblastic cells, within a moderately vascularized fibrous stroma. The child underwent complete surgical excision with no evidence of recurrence at one year follow up. MNTI is an unusual tumor occurring in early childhood with a predilection for the maxilla. Clinical findings, CT scan and MRI may allow a preoperative diagnosis. PMID:27095686

    Full text: NETs are heterogeneous group of tumors which take up amino acids, transform them into biogenic amines and store the amines in vesicles, this forms the basis of uptake of 18F-DOPA in these tumors. These tumors can be small and situated almost throughout the body and may also present as advanced disease with multiple metastatic sites. Like in management of any other tumor it is imperative to stage the status of disease in NETs for the effective management of these patients and 18F-DOPA PET/CT is one such imaging modality used in the evaluation of neuroendocrine tumors (NETs). Here is our initial experience using 18F-DOPA PET/CT imaging in these patients. Twenty-seven patients with NETs (carcinoids, medullary thyroid carcinomas, phaeochromocytomas Insulinoma) were prospectively enrolled and scheduled for 18F-DOPA PET/CT. Wherever possible, tissue diagnosis was attempted. Results obtained were compared with other conventional diagnostic procedures (mainly 18F-FDG PET/CT, and 68Ga-DOTANOC PET/CT, and with ultrasound, CT, etc) and with follow-up. 18F-DOPA PET/CT identified 17/24 positive cases in either the primary/metastatic/recurrent tumor. In case of Insulinoma 18F-DOPA was found to be most superior than other imaging modalities in localizing the disease and staging of disease

    The expression pattern of thyroid transcription factor 1 (TTF-1) and neuroendocrine markers, neuron cell adhesion molecule (NCAM; CD56), chromogranin A (CgA) and synaptophysin (Syp), of different lung cell lineages was histologically analyzed in 15 normal human fetal lungs and 12 neuroendocrine tumors (NETs) using immunohistochemical methods. During pseudoglandular phase strong nuclear TTF-1 staining was detected in the columnar nonciliated epithelial cells, while NCAM, CgA and Syp had a moderate expression in the proximal airways and mild expression in the distal airways. Neuroendocrine cells (NECs) in proximal lung airway were co-localizing TTF-1 and other neuroendocrine markers while neuroendocrine bodies (NEBs) exhibit only staining with NCAM and Syp. In the canalicular phase TTF-1 nuclear staining was expressed only in several epithelial cells in proximal airways, while budding airways epithelium showed strong TTF-1 expression. Expression of NCAM, CgA and Syp in this phase equals the one in pseudoglandular phase. NEBs cells were co-localizing TTF-1 and NCAM in proximal airways and few NECs in distal airway were co-localizing TTF-1 and Syp. TTF-1 staining in the saccular phase was limited to subsets of epithelial cells in the proximal airways with stronger positivity in the distal airways. NCAM expression is moderate only in proximal airways, while Syp and CgA show mild expression in proximal and distal airways. NECs were co-localizing TTF-1 and NCAM in proximal lung airway. With regard to NECs, all small cell lung cancer (SCLC) cells had strong TTF-1, NCAM, Syp and CgA positivity and TTF-1 co-localized with other neuroendocrine markers. All pulmonary typical carcinoids were TTF-1 negative, while pulmonary atypical carcinoids were focal positive for TTF-1 and some neoplastic cells co-localized TTF-1 with neuroendocrine markers. Our results indicate that TTF-1 expression in NECs suggests a possible role in their normal development and differentiation. Our

    Abnormalities of the short arm of chromosome 12 are relatively common in hematologic malignancies and deletions of the region. 12p12-13 are found in approximately 5% of the patients with acute lymphoblastic leukemia (ALL). As a potent inhibitor of cyclin-dependent kinases, p27KIP1 prevents the progression of the cell cycle and the gene encoding p27KIP1 represents a potential tumor-suppressor gene. Its recent assignment to the chromosomal region (12p12.3) prompted us to study the p27KIP1 gene in a series of 61 children with ALL. Microsatellite polymorphic markers flanking the p27KIP1 gene were analyzed to detect losses of heterozygosity (LOH). Eleven patients displayed LOH for at least one of the markers. The deleted are encompassed the p27KIP1 gene locus in 10 cases, but inactivation of the remaining allele by deletion, translocation, or mutation was never observed. In addition, in 1 patient, the p27KIP1 gene was situated outside of the region of LOH. Thus, p27KIP1 does not seem to be the target gene of 12p12-13 alterations. However, this study indicates that 12p12-13 alterations at the molecular level, which are present in about 27% of the children with B-lineage ALL, are much more common than had previously been reported by usual chromosome analysis. Moreover, LOH mapping allowed us to better define the location of a putative tumor-suppressor gene implicated in these malignancies and should therefore help in identifying this gene.

    Neuroendocrine tumors (NET) include a spectrum of malignancies arising from neuroendocrine cells throughout the body. The objective of this clinical investigation of retrospectively and prospectively collected data was to describe the prevalence, demographic data, clinical symptoms and methods of diagnosis of NET and the treatment and long-term follow-up of patients with NET. Data were provided by the participating centers and assessed for consistency by internal reviewers. All the cases were centrally evaluated (when necessary) by the pathologists in our group. The tissue samples were reviewed by hematoxylin and eosin and immunohistochemical staining techniques to confirm the diagnosis of NET. In total, 532 cases were documented: 461 gastroenteropancreatic-NET (GEP-NET) and 71 bronchial NET (BNET). All the tumors were immunohistochemically defined according to the World Health Organization (WHO) and European Neuroendocrine Tumor Society criteria. The most common initial symptoms in GEP-NET were abdominal pain, diarrhea, bowel obstruction, flushing, gastrointestinal bleeding and weight loss. The most common tumor types were carcinoid (58.0%), non-functional pancreatic tumor (23.0%), metastatic NET of unknown primary (16.0%) and functional pancreatic tumor (3.0%). Of the BNET, 89.0% were typical and 11.0% atypical carcinoids. Of the patients with GEP-NET, 59.2% had distant metastasis at diagnosis. The locations of the primary tumors in GEP-NET were the small bowel (26.9%), pancreas (25.2%), colon-rectum (12.4%), appendix (7.6%), stomach (6.9%), esophagus (2.8%), duodenum (2.0%) and unknown primary (16.3%). The histological subtypes based on the WHO classification were well-differentiated NET (20.1%), well-differentiated neuroendocrine carcinomas (66.5%) and poorly differentiated neuroendocrine carcinomas (10.3%). Overall, 67.3% of the patients underwent surgery, 41.2% with curative intent and 26.1% for palliative purposes. The 5-year survival rates were 65.1% (95

    A 59-year-old woman was admitted to our hospital because of recurrent follicular lymphoma (FL). Colonoscopic examination revealed a rectal submucosal tumor (SMT) without any erosions and ulcers. In this patient, it was difficult to distinguish non-Hodgkin's lymphoma (NHL) invasion from other disorders of the colon including carcinoid tumor merely based on endoscopic findings. Histopathologic and immunohistochemical studies on biopsy specimens showed an infiltration of atypical lymphocytes that were positive for CD20 and BCL2 but negative for UCHL-1. Fluorescence in situ hybridization on paraffin-embedded tissue sections (T-FISH) identified a translocation of BCL2 with IGH gene.Based on these findings, the tumor was defined as an invasion of FL. T-FISH method is useful for the detection of a monoclonality of atypical lymphocytes in an SMT of the gastrointestinal tract, and particularly for the detection of chromosomal translocations specific to lymphoma subtypes.

    Myelodysplastic syndrome (MDS) comprises of a heterogeneous group of bone marrow disorders resulting from a clonal stem cell defect characterised by cytopenias despite a relatively hypercellular marrow, ineffective hematopoiesis, morphological dysplasia in the marrow elements, no response to hematinics such as iron, B12 or folic acid and risk of progression to leukemia. Myelodysplastic syndrome in childhood is extremely rare and accounts for less than 5% of all hematopoietic neoplasms in children below the age of 14 y. The primary MDS in children, also known as de novo MDS differs from secondary MDS which generally follows congenital or acquired bone marrow (BM) failure syndromes as well as from therapy related MDS, commonly resulting from cytotoxic therapy. MDS associated with Down syndrome which accounts for approximately one-fourth of cases of childhood MDS is now considered a unique biologic entity synonymous with Down syndrome-related myeloid leukemia and is biologically distinct from other cases of childhood MDS. Refractory cytopenia of childhood (RCC) is the commonest type of MDS. Genetic changes predisposing to MDS in childhood remain largely obscure. Monosomy 7 is by-far the commonest cytogenetic abnormality associated with childhood MDS; however most cases of RCC show a normal karyotype. Complex cytogenetic abnormalities and trisomy 8 and trisomy 21 are also occasionally observed. The most effective and curative treatment is Hematopoietic stem cell transplantation and this is particularly effective in children with the monosomy 7 genetic defect as well as those displaying complex karyotype abnormalities provided it is instituted early in the course of the disease.

  9. The Contrasting Role of p16Ink4A Patterns of Expression in Neuroendocrine and Non-Neuroendocrine Lung Tumors: A Comprehensive Analysis with Clinicopathologic and Molecular Correlations.

    Nicola Fusco

    Full Text Available Lung cancer encompasses a constellation of malignancies with no validated prognostic markers. p16Ink4A expression has been reported in different subtypes of lung cancers; however, its prognostic value is controversial. Here, we sought to investigate the clinical significance of p16Ink4A immunoexpression according to specific staining patterns and its operational implications. A total of 502 tumors, including 277 adenocarcinomas, 84 squamous cell carcinomas, 22 large cell carcinomas, 47 typical carcinoids, 12 atypical carcinoids, 28 large cell neuroendocrine carcinomas, and 32 small cell carcinomas were reviewed and subjected to immunohistochemical analysis for p16Ink4A and Ki67. The spectrum of p16Ink4A expression was annotated for each case as negative, sporadic, focal, or diffuse. Expression at immunohistochemical level showed intra-tumor homogeneity, regardless tumor histotype. Enrichments in cells expressing p16Ink4A were observed from lower- to higher-grade neuroendocrine malignancies, whereas a decrease was seen in poorly and undifferentiated non-neuroendocrine carcinomas. Tumor proliferation indices were higher in neuroendocrine tumors expressing p16Ink4A while non-neuroendocrine malignancies immunoreactive for p16Ink4A showed a decrease in Ki67-positive cells. Quantitative statistical analyses including each histotype and the p16Ink4A status confirmed the independent prognostic role of p16Ink4A expression, being a high-risk indicator in neuroendocrine tumors and a marker of good prognosis in non-neuroendocrine lung malignancies. In this study, we provide circumstantial evidence to suggest that the routinary assessment of p16Ink4A expression using a three-tiered scoring algorithm, even in a small biopsy, may constitute a reliable, reproducible, and cost-effective substrate for a more accurate risk stratification of each individual patient.
