Nonfunctioning pancreatic neuroendocrine carcinoma (NPNEC) is a poorly differentiated neuroendocrine carcinoma and a rare type of pancreatic cancer. Computed tomography (CT)-based imaging is currently the most effective method for diagnosing and classifying NPNEC. The present study investigated the clinical features and CT manifestations of this disease. The CT manifestations and clinical data of 13 patients with NPNEC, confirmed by surgery or needle biopsy, were retrospectively analyzed. None of the 13 patients exhibited endocrine-related symptoms and a single lesion with a variable position in the pancreatic was observed in all patients...

Synchronous bilateral breast cancer is rare, and oncocytic carcinoma is an even rarer breast cancer histological subtype. In general, oncocytic tumors are defined as neoplasms with eosinophilic granular cytoplasm and have been reported in various organs. Oncocytic carcinoma of the breast was first documented by Gădăleanu and Craciun in 1987, and 48 cases have since been reported. The present study reports a case of synchronous bilateral breast oncocytic carcinoma. The patient was a 78-year-old woman. Although she exhibited no symptoms, chest computed tomography revealed three multinodular breast tumors: Two in the right breast and one in the left...

The inhibitor of growth family, member 3 (ING3) protein may be capable of blocking the cell cycle via activating p53-transactivated promoters of p21 and Bcl2-associated X protein, and may induce apoptosis via a Fas/caspase-8-dependent signaling pathway. In the present study, immunohistochemistry was performed in order to characterize the expression profile of ING3 protein in tissue microarrays containing mouse and human normal tissue, human hepatocellular (n=62), renal clear cell (n=62), pancreatic (n=62), esophageal squamous cell (n=45), cervical squamous cell (n=31), breast (n=144), gastric (n=196), colorectal (n=96), ovarian (n=208), endometrial (n=96) and lung carcinoma (n=192)...

The current study documents an unusual case of iris metastasis as the first sign of small cell lung cancer (SCLC) and reviews the relevant literature to increase understanding and awareness of this rare condition. A 59-year-old male chronic smoker presented with a painful and red right eye without any disturbance of vision. The patient also complained of associated chronic cough and anorexia. Upon examination, an exfoliative, pinkish-white lesion of the right iris was observed. A systemic work-up was performed, which incidentally detected metastatic SCLC in the lower lobe of the right lung and was confirmed by histopathological examination...

Tumor-to-meningioma metastasis (TMM) is a fairly uncommon phenomenon. Only 7 cases of prostate cancer with TMM have previously been described in the literature. The present study aimed to report a case of prostate cancer TMM, and to discuss the relevant clinical and neuroimaging aspects of this condition. A 68-year-old patient presented with headaches, poor visual acuity in the left eye and ipsilateral eyelid droop 3 years after a Simpson II resection of a left sphenoid wing meningioma. Computed tomography revealed a hyperdense area suggestive of a recurrent left sphenoid wing meningioma...

Lung cancer is the leading cause of cancer-associated mortality worldwide. The present study investigated the effects of K9(C4H4FN2O2)2Nd(PW11O39)2·25H2O (FNdPW), a chemically synthesized polyoxometalate that contains rare earth elements, on lung cancer growth, and explored the mechanism underlying its actions. The effects of FNdPW on the cell viability and apoptosis of human lung cancer A549 cells were measured using MTT assay, acridine orange/ethidium bromide staining and electron microscopy. The expression of apoptosis-related proteins, including B-cell lymphoma (Bcl)-2-associated death promoter (Bad), phosphorylated (p)-Bad, X-linked inhibitor of apoptosis (XIAP), apoptosis-inducing factor (AIF), Bcl-2-associated X protein (Bax) and Bcl-2, was determined by western blotting...

Glioma is the most common human brain cancer and has poor prognosis. Messenger RNA profiling identified that sineoculis homeobox homolog 1 (Six1) is dysregulated in glioma tumor progenitor cells from glial progenitor cells isolated from normal white matter. However, the expression and role of Six1 in glioma remains unclear. The purpose of the present study was to investigate the expression level of Six1 in glioma tissues and the association between Six1 expression and clinicopathological characteristics and prognosis of gliomas...

Gemcitabine is frequently used for the treatment of a number of different cancer types. Gemcitabine-related thrombotic microangiopathy (TMA) has rarely been described, but it is a life-threatening complication. The incidence of the complication varies between 0.015 and 1.4%. The present study reports the case of a 63-year-old Caucasian male who was treated with 3 cycles of carboplatin plus gemcitabine, followed by 7 cycles of gemcitabine only, and developed clinical symptoms that, together with laboratory findings, were compatible with a diagnosis of hemolytic uremic syndrome TMA...

BACKGROUND: Younger breast cancer survivors face a unique set of treatment-related issues that have enormous impact on quality of life and psychological well-being. Although there is often a profound and distressing impact of treatment on self-image and sexual function, women rarely receive any attention for these issues. Unfortunately, most clinicians receive no training on how to inquire about these problems and most clinicians feel unprepared to discuss them. Often this silence is due to a lack of ready resources and uncertainty of appropriate strategies for rehabilitation...

Background/Aims: Serum alpha-fetoprotein (AFP) measurement is commonly included in a health check-up program in Korea. However, its benefits remain uncertain. We analyzed whether AFP measurement should be included in a general health check-up program to screen for hepatocellular carcinoma (HCC). Methods: A total of 36,552 adults aged 18 years or older-who participated in a routine health examination including AFP determination between January 2009 and December 2009 at the Health Promotion Center, Samsung Medical Center, South Korea-were analyzed...

BACKGROUND: Malignant pleural mesothelioma is a rare tumor with a dismal prognosis, usually presenting with recurrent effusions. However, the majority of malignant pleural effusions are due to lung adenocarcinoma (AdC). The distinction between these tumors has considerable therapeutic and medicolegal implications and can be very challenging both histologically and cytologically. Appropriate immunohistochemistry (IHC) is required to support the diagnosis. MicroRNA (miRNA) expression analysis could be a viable diagnostic tool for distinguishing between these tumors...

Pediatric melanoma, although rare, is the most common skin cancer in children. Our current knowledge on pediatric melanoma incidence trends is expanding, as several studies have addressed this issue with conflicting results. Known risk factors for pediatric melanoma include family history of melanoma, a previous history of malignancy, large congenital nevi, numerous melanocytic nevi, sunburns, increased UV exposure and a sun-sensitive phenotype. In younger children melanoma more often presents with atypical features, such as a changing, amelanotic or uniformly colored, often bleeding lesion, not fulfilling in most cases the conventional ABCDE criteria...

Background: Higher fruit consumption is associated with lower risk of cardiovascular disease (CVD). Substantial uncertainties remain, however, about the associations of fruit consumption with all-cause mortality and mortality from subtypes of CVD and major non-vascular diseases, especially in China. Methods: In 2004-08, the nationwide China Kadoorie Biobank Study recruited > 0.5 million adults aged 30-79 years from 10 diverse localities in China. Fresh fruit consumption was estimated using an interviewer-administered electronic questionnaire, and mortality data were collected from death registries...

Therapeutic monoclonal antibodies targeting cell surface or secreted antigens are among the most effective classes of novel immunotherapies. However, the majority of human proteins and established cancer biomarkers are intracellular. Peptides derived from these intracellular proteins are presented on the cell surface by major histocompatibility complex class I (MHC-I) and can be targeted by a novel class of T-cell receptor mimic (TCRm) antibodies that recognise similar epitopes to T-cell receptors. Humoural immune responses to MHC-I tetramers rarely generate TCRm antibodies and many antibodies recognise the α3 domain of MHC-I and β2 microglobulin (β2m) that are not directly involved in presenting the target peptide...

BACKGROUND: Brain metastases (BM) from colorectal cancer (CRC) are rare, but the incidence is suspected to rise as treatment of metastatic (m) CRC improves. The aim of this study was to identify possible biological and clinical characteristics at initial presentation of mCRC that could predict later risk of developing BM. Furthermore, we wished to estimate the incidence of BM in long-term surviving patients. MATERIAL AND METHODS: We conducted a retrospective study on a Danish multicenter cohort of patients with mCRC who received cetuximab and irinotecan (CetIri) as third-line treatment...

Breast metastases of solid extramammary tumors are very rare in comparison to primary malignancies of the breast and account for only 0.33-6.3% of all malignant neoplasms of the breast. The most common primary tumors are malignant melanoma, distant sarcomas, lung cancer, ovarian cancer, renal cell cancer and thyroid cancer in decreasing order of frequency. This review article summarizes the clinical features and the different imaging findings of breast metastases from different extramammary solid tumors. Breast metastases are often incidental findings in computed tomography (CT) or positron emission tomography CT (PET-CT) imaging...

Nasser Altorki, Sebron Harrison
The majority of patients with operable esophageal cancers present with locally advanced disease, for which surgical resection as a sole treatment modality has been historically associated with poor survival. Even following radical resection, most of these patients will eventually succumb to their disease due to distant metastasis. For this reason, there has been intense interest in the role of neoadjuvant therapy. Neoadjuvant therapy primarily consists of either chemotherapy, radiation therapy, or a combination of the two...

Mortality from esophageal cancer remains high despite advances in medical therapy. Although the incidence of squamous cell carcinoma of the esophagus remains unchanged, the incidence of the esophageal adenocarcinoma has increased over time. Gastroesophageal reflux disease (GERD and obesity are contributing factors to the development of Barrett's esophagus and subsequent development of adenocarcinoma. Early recognition of the disease can lead to resection of esophageal cancer prior to the development of lymphovascular invasion...

Adrenocortical carcinoma is a rare neoplasm with a poor prognosis. Very important advances have been made in the identification of the genetic determinants of adrenocortical carcinoma pathogenesis but our understanding is still limited about the mechanisms that determine cancer spread and metastasis. One major problem hindering preclinical experimentation for new therapies for adrenocortical carcinoma is represented by the lack of suitable animal models for metastatic disease. With the aim to overcome these limitations, in this study we tested several protocols in order to establish a mouse xenograft model of metastatic adrenocortical carcinoma...
