OBJECTIVES: Peptide receptor radionuclide therapy (PRRT) with lutetium-177 (Lu)-DOTATATE is regarded as a safe treatment option with promising results for patients with neuroendocrine neoplasia (NEN). We aimed to study the absorbed organ and tumor doses, the renal and hematological toxicity as well as their mutual interaction. Another aim was the identification of adverse effects as possible predictors which may affect survival. METHODS: A total of 30 (14 female and 16 male) patients with inoperable/metastatic NEN were treated with 7...

Ga-DOTATATE, a positron-emitting somatostatin analog, has been approved by the Food and Drug Administration for imaging neuroendocrine tumors (NETs). The presence of a second primary malignancy is common in NETs; however, synchronous primary malignancy in the thyroid has rarely been reported. The value of Ga-DOTATATE in medullary thyroid cancer is being investigated and is currently recommended for use when treatment with somatostatin analogs is an option. We present a 55-year-old man with abdominal pain associated with well-differentiated NET liver metastases and incidental medullary thyroid carcinoma demonstrated on a Ga-DOTATATE PET/CT...

Pancreatic cancer represents one of the most aggressive types of cancer, resulting in a late diagnosis and rapid death (poor overall survival). After adenocarcinoma (counting almost 80% of cases of pancreatic cancer), the second category, as frequency, is represented by the family of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Pancreatic cancer is characterized by genetic heterogeneity and may results in different evolution among metastases, which may acquire driver mutations with the ability to transform under the action of several cancer treatments...

Background: Since the early 1990s, the minimally invasive image-guided therapies used in interventional oncology to treat hepatocellular carcinoma have continued to evolve. Additionally, the range of applications has been expanded to the treatment of hepatic metastases from colorectal cancer, neuroendocrine tumors, cholangiocarcinoma, breast cancer, melanoma, and sarcoma. Methods: We searched the literature to identify publications from 1990 to the present on various image-guided intraarterial therapies and their efficacy, as well as their role in the management of primary and secondary liver malignancies...

In this review, we outline the biology and management of patients with carcinosarcomas and related malignancies, which are often included under the broader concept of sarcomatoid carcinomas. Carcinosarcomas are unusual tumors that are commonly gynecologic in origin, where they are referred to as malignant mixed Müllerian tumors, but may appear in any anatomic site. Although a variety of hypotheses have been presented as to the biphasic nature of these tumors, carcinosarcomas seem to represent the best example in human cancers of the concept of epithelial-mesenchymal transition (EMT), in which the two parts of the tumor are genomically related to one another, as opposed to the mesenchymal component that represents a second neoplasm or (benign) reactive process...

In cancer of unknown primary (CUP), metastases are clinically and histologically confirmed, but the primary tumor site remains elusive after extensive work-up. CUPs make up for 2-3% of all epithelial malignancies. The two prevailing histologies are adenocarcinomas and undifferentiated carcinomas, whereas squamous cell carcinomas, neuroendocrine carcinomas and rare histologies account for the remaining 10%. The diagnostic work-up in CUP relies strongly on a detailed immunohistological (IHC) analysis in order to characterize the tumor type, nowadays aided by molecular techniques...

Bronchopulmonary (BP) neuroendocrine tumors (NETs) comprise a spectrum of tumors that develop from respiratory neuroendocrine cells and represent ~20% of all lung neoplasia and ~30% of all NETs. The only curative treatment is surgical resection. For well-differentiated forms (typical and atypical carcinoids), medical therapy ranges from bioactive agents (e.g., somatostatin analogs), to biotherapy (e.g., everolimus), standard chemotherapy and peptide receptor radionuclide therapy (PRRT). PRRT with radiolabeled somatostatin analogs is an innovative treatment for inoperable or metastasized, well/moderately differentiated, NET...

Primary neuroendocrine tumors of the thymus (NETTs) are rare and biologically very aggressive neoplasms, usually located in the anterior mediastinal space. They are more frequently observed in males, in their fourth/fifth decades of life. In 50% of cases, NETTs are associated with endocrinopaties [Cushing's syndrome, acromegaly or Multiple Endocrine Neoplasia-1 (MEN-1) syndrome]. NETTs very often present with invasion of the surrounding mediastinal anatomical structures. Surgery, even in advanced stages, is the mainstay of treatment: a compete resection through a median sternotomy or a combined access (sternotomy + thoracotomy) should be always attempted...

Intestinal neuroendocrine tumors (NETs) constitute a heterogeneous group with duodenal, small intestinal, colonic and rectal NETs. They constitute more than half of all NETs, with the highest frequencies in the rectum, small intestine, and colon. The tumor biology varies with the location of the primary tumor as well as with the grade and staging of the tumor. Small intestinal NETs usually present low proliferation and are treated in the first line with somatostatin analogs according to current guidelines. If progression occurs, one can add interferon alpha or change the treatment to everolimus...

Although the majority of neuroendocrine tumors of the small intestine (siNETs) classified as low-grade G1 or G2 show slow local growth, they are frequently diagnosed at an advanced stage of metastatic disease. The surgical treatment is curative in stages I-III or palliative in stage IV in an attempt to avoid local complications of bowel obstruction and ischemia of the small bowel by unremoved lymph node metastases. Individualized surgical procedures performed by experienced surgeons considering tumor multifocality and the primary extent of lymph node metastases along the mesenteric vessels are recommended to remove as much tumor volume as possible, while avoiding major complications intraoperatively and small bowel syndrome postoperatively...

INTRODUCTION: Neuroendocrine tumors (NETs) are a heterogeneous group of tumors. NET of colon represent less than 1% of colonic tumors. Synchronous liver metastases, present in 75-80%, are considered significant adverse prognostic indicators. Liver is the second commonest site for metastasis in patients with colorectal neuroendocrine tumors. Available treatment options include surgical resection, chemotherapy, biotherapy. Surgery is the gold standard for curative therapy and it is strictly related to the localization, the grade of tumor, and the stage of disease...

BACKGROUND: Radioembolization (RE) with intra-arterial administration of (90)Y microspheres is a promising technique for the treatment of liver metastases from small intestinal neuroendocrine tumors (SI-NET) not amenable to surgery or local ablation. However, studies comparing RE to other loco-regional therapies are lacking. The aim of this randomized study was to compare the therapeutic response and safety after RE and bland hepatic arterial embolization (HAE), and to investigate early therapy-induced changes with diffusion-weighted MRI (DWI-MRI)...

BACKGROUND & AIMS: Survival times vary among patients with neuroendocrine tumors (NETs)-even among those with the same site, stage, and grade of primary tumor. This makes it difficult to select treatment for patients with unresectable NETs, because some patients can survive decades without treatment. 68Gallium-DOTATATE positron emission tomography with computed tomography (68Ga-DOTATATE PET/CT) is a sensitive imaging technique for detection of NETs. We investigated the prognostic accuracy of 68Ga-DOTATATE PET/CT analysis of tumor volume in patients with NETs...

Neuroendocrine tumors (NET) represent the variability of almost benign lesions either secreting hormones occurring as a single lesion up to malignant lesions with metastatic potential. Treatment of NET is usually performed by surgical resection. Due to the rarity of NET, surgical treatment is mainly based on the experience and recommendations of experts and less on the basis of prospective randomized studies. In addition, the development and establishment of new surgical procedures is made more difficult by their rarity...

Thyroid carcinoma (TC) represents 1-2 % of all human tumors, and is the seventh most common tumor. Women are in large majority among new patients. For women, this is the fifth most common tumor. In the Czech Republic, 1 143 new cases of TC were diagnosed in 2015. It is the tumor with the highest increase in incidence. Among newly diagnosed tumors, most of those are differentiated thyroid gland carcinomas (DTCs) originating from follicular thyroid cells. These tumors are follicular and papillary carcinomas and Hurthle carcinoma, accounting for 95 % of new cases...

Diagnostic imaging of jejuno-ileal neuroendocrine tumors (NETs) has been described as challenging. Follow-up requires the detection of metastatic spread as well as screening for local recurrence. Multimodal imaging concepts must often be applied.We report the case of a 45-year-old man with a history of ileal NET. At 2 points in follow-up of our patient, information provided by high-end ultrasound changed prognosis and treatment considerably: when positron emission tomography/computed tomography newly detected suspected hepatic metastases, contrast-enhanced ultrasound correctly identified the lesions as intrahepatic vascular shunts...

Metastatic tumors to the breast are rare but constitute a major diagnostic dilemma. Of these, non-mammary carcinomatous metastases to the breast are particularly challenging and, without a clinical history, may be extremely difficult to distinguish from primary breast carcinoma (PBC). We specifically studied metastatic tumors of pulmonary origin, as the lung is one of the major primary sites for carcinomatous metastasis to breast. Sixteen metastatic lung tumors to the breast were identified in our archives between 1996 and 2017 including 12 non-small cell lung carcinomas (NSCLC), one large-cell neuroendocrine, one atypical carcinoid, and two small-cell carcinomas...
