Andrew A Fanous, Dheerendra Prasad, David Mathieu, Andrew J Fabiano
Stereotactic radiosurgery (SRS) is the use of a single high dose of radiation, stereotactically directed to an intracranial region of interest, in order to create a lesion or obliterate a preexisting one. This technology has evolved over the years into the use of multiple radiation sources oriented at a variety of angles, thus permitting the creation of various treatment target shapes. This allows for non-open surgical treatment of intracranial pathologies, which significantly decreases the risk of morbidity...

Osteosarcoma is a common and highly malignant tumour in children and teenagers that is characterized by drug resistance and high metastatic potential. Patients often develop pulmonary metastasis and have a low survival rate. However, the mechanistic basis for pulmonary metastasis remains unclear. To identify key gene and pathways associated with pulmonary metastasis of osteosarcoma, the authors downloaded the gene expression dataset GSE85537 and obtained the differentially expressed genes (DEGs) by analyzing high‑throughput gene expression in primary tumours and lung metastases...

Tae-Hun Kim, Sung-Gook Cho
Kisspeptin is a protein encoded by the KISS1 gene, which has been reported to suppress the metastatic capabilities of various types of cancer cells, through the activation of its G‑protein coupled receptor GPR54. However, the molecular mechanisms underlying the involvement of kisspeptin‑mediated signaling in the inhibition of cancer cell migration and invasion have yet to be elucidated. The present in vitro cell proliferation, migration and invasion assays and in vivo experimental metastasis studies demonstrated that kisspeptin‑induced eukaryotic translation initiation factor 2α kinase 2 (EIF2AK2) activation suppressed the metastatic capabilities of several types of cancer cells...

OBJECTIVE: Malignant melanomas presenting with unknown primaries are uncommon. In the majority of cases metastases of occult melanoma were detected in skin or in lymph nodes. Melanoma can rarely occur as a primary or metastatic intramammary tumor. CASE REPORT: We report the case of a 58-year-old Caucasian woman who came to our department with a voluminous mass in her right breast. Histopathological examination found metastasis of epithelioid melanoma with unknown primary lesion...

Mucosal melanoma is a rare aggressive cancer with a very poor prognosis. Clinical and pathological characteristics of mucosal melanoma differ from those of cutaneous melanoma and there are no established management guidelines for mucosal melanoma. Complete surgical excision is one of the most effective treatments for localized lesions, while targeted therapies and immunotherapies, such as monoclonal antibodies that target cytotoxic T-lymphocyte-associated molecule-4, and the programmed death (PD)-1/PD-ligand 1 pathway inhibitors, are treatment options for unresectable or metastatic lesions...

Nano-Pulse Stimulation (NPS) as a developing technology has been studied for minimally invasive, non-thermal local cancer elimination for more than a decade. Here we show that a single NPS treatment results in complete regression of the poorly immunogenic, metastatic 4T1-Luc mouse mammary carcinoma. Impressively, spontaneous distant organ metastases were largely prevented, even in those animals with incomplete tumor regression. All tumor-free mice were protected from secondary tumor cell challenge, demonstrating a vaccine-like effect...

A 41-year-old female presented with a pedunculated mass in the upper esophagus and bilateral lymphadenopathy. Biopsies suggested a neuroendocrine tumor, possibly carcinoid, and ensuing imaging revealed cervical lymph node metastases. The esophageal mass was removed endoscopically and discovered by pathologists to closely resemble medullary thyroid carcinoma (MTC) on immunohistochemistry staining. Following surgery, further work up demonstrated very high serum calcitonin levels, suggestive of medullary thyroid carcinoma, however the thyroid gland was normal on ultrasound...

Ameloblastoma is a rare low-grade odontogenic tumor of epithelial origin. The World Health Organization (WHO) has defined malignant ameloblastoma (MA) as a histologically benign-appearing ameloblastoma that has metastasized. Treatment of the primary ameloblastoma usually consists of radical excision of the tumor and adjuvant radiotherapy. Chemotherapy should be used to treat metastases due to its indolent clinical course. Presented here is the case of a 43-year-old woman who was admitted to a hospital in 2006 with a large mass involving the neck and left mandible...

Introduction Intracranial tumors (ICTs) are a diverse group of malignancies that pose an immediate threat to patients' lives, no matter their local or metastatic origin, benign or malignant nature. These lesions have severe clinical courses and need to be diagnosed and treated as soon as possible, with pathological verification being the pivotal moment in the process of determining curative modalities. Aim The aim of this study was to compare the incidence of histologically confirmed ICTs in Eastern Bulgaria, based on their type (primary, metastatic, and non-volume occupying lesions (NVOL)), their respective subtypes, and incidence in a descriptive manner...

Pulmonary large-cell neuroendocrine carcinoma (LCNEC) is a rare and malignant form of lung cancer with a poor prognosis for patients. The common sites of metastases are the liver, adrenal glands, bone and brain. LCNEC rarely metastasizes to the small intestine, ovaries, tonsils, mandible, vulva or spine. To the best of our knowledge, there have been no reports of leptomeningeal metastasis of LCNEC to date. The present case report describes an unusual case of leptomeningeal metastasis from pulmonary LCNEC alongside a review of the literature...

The metastatic spread of breast carcinoma to the stomach is rare. There are a small number of previous studies that report metastases from the breast to the stomach and these provide limited information regarding this infrequent event. Consequently, the clinicopathological features, clinical outcomes and the optimal treatment for these patients remain to be elucidated. In the present study, 78 cases of gastric metastases from breast cancer, including the current case, were identified from previous studies between 1960 and 2015...

Breast cancer is the most common malignant disease occurring in women. Conservative breast cancer surgery followed by radiation therapy is currently the standard treatment for this type of cancer. The majority of metastases occur within the scar, which initiated a series of studies. As a result, clinical trials aimed to assess whether localized radiotherapy, as intraoperative radiotherapy (IORT), may more effective in inhibiting the formation of local recurrence compared with the standard postoperative whole breast radiotherapy...

Intercellular adhesion molecule (ICAM)-1, is a transmembrane glycoprotein of the immunoglobulin (Ig)-like superfamily, consisting of five extracellular Ig-like domains, a transmembrane domain and a short cytoplasmic tail. ICAM-1 is expressed in various cell types, including endothelial cells and leukocytes, and is involved in several physiological processes. Furthermore, it has additionally been reported to be expressed in various cancer cells, including melanoma, colorectal cancer and lymphoma. The majority of studies to date have focused on the expression of the ICAM-1 on the surface of tumor cells, without research into ICAM-1 expression at sites of metastasis...

A 61-year-old man who had undergone total nephrouretectomy eight months earlier for right ureteral carcinoma was referred for the investigation of elevated serum hepatobiliary enzymes. Computed tomography revealed a small mass invading the lower bile duct. Duodenoscopy revealed a central ulcerative tumor near the major papilla, and a biopsy histologically confirmed metastatic ureteral carcinoma. Endoscopic biliary stenting ameliorated the cholangitis, and gemcitabine-based chemotherapy was initiated. The patient was stable for a year until a duodenal stenosis developed and required duodenal stenting...

We report an 80-year-old woman with EGFR-mutant lung adenocarcinoma with multiple brain metastases (BMs). All lesions including BM showed a successful resolution after initiating daily 150 mg erlotinib. However, a grade 2 bilirubin-increase developed, and it was necessary to reduce the dose of erlotinib to 50 mg every other day, which aggravated BM. Switching erlotinib to afatinib led to the resolution of BM without an increase in the bilirubin level. Our results indicate that afatinib is an important treatment option when erlotinib-induced hepatotoxicity develops, regardless of the patients' age...

REVIEW
Sean Robinson Smith, Ashish Khanna, Eric M Wisotzky
Lung cancer is the number one cause of cancer-related death worldwide, and is often detected in the later stages. Use of low-dose chest computed tomography in at-risk patients provides earlier detection and is being adopted as the standard screening tool, replacing less precise methods of radiography and sputum cytology. In the past, late detection of disease meant that rehabilitation interventions attempted to salvage function and to improve aerobic capacity to the point where patients could tolerate the sometimes-extensive oncologic treatment, including lobectomy or pneumonectomy...
