Edward B Stelow, Hadi Yaziji
Pathologists use immunohistochemistry is their day-to-day practices to assist in distinguishing site of origin of metastatic carcinomas. Here, the work-up is discussed neuroendocrine carcinomas, squamous cell carcinomas and adenocarcinomas with particular attention to tumor incident rates and predictive values of the best-performing immunohistochemical markers.

Cosmetic injection of dermal fillers is common, with late complications increasingly recognized. Herein, we report a granulomatous reaction to hyaluronic acid filler occurring during the use of neratinib. A woman in her fifties, with metastatic adenocarcinoma of unknown primary involving the skin and bones, was referred for new-onset facial swelling. Notable past medical history included progression of disease on carboplatin/paclitaxel and a hemithyroidectomy for papillary thyroid cancer. This article is protected by copyright...

PURPOSE: High thoracotomy allows access to the anterior cervicothoracic and upper thoracic vertebrae; however, traditional techniques transect shoulder girdle muscles, leading to postoperative shoulder dysfunction. Muscle-sparing techniques diminish this concern, but often sacrifice the quality of exposure. We describe a novel muscle-sparing, high thoracotomy approach for the treatment of ventral cervicothoracic and upper thoracic spine lesions. METHODS: A novel muscle-sparing, high thoracotomy approach is described, utilizing a midline posterior incision with lateral extension from the lateral decubitus position...

OBJECTIVES/HYPOTHESIS: The unknown primary of the neck is commonly encountered by the head and neck surgeon. Despite the exhaustive diagnostic tools employed in traditional detection protocols, many unknown primaries are not found, and the patient is subjected to wide-field radiation and chemotherapy during treatment. Localizing the primary tumor has demonstrated therapeutic benefits, improved quality of life, and overall survival. The authors' objective was to determine the efficacy of a new management protocol for unknown primaries of the head and neck...

BACKGROUND: Extrapulmonary neuroendocrine carcinomas (NECs) are poorly studied and are managed similar to lung NECs, which may not account for differences between the 2 groups of tumors as well as the heterogeneity within extrapulmonary NEC. METHODS: Data from the Surveillance, Epidemiology, and End Results program between 1973 and 2012 were used to estimate the relative percentages of lung NECs and subgroups of extrapulmonary NECs, epidemiological patterns at these sites, and the median and 5-year overall survival rates...

BACKGROUND: Treatment for squamous cell carcinoma (SCC) of unknown primary consists of radiotherapy (RT) +/- chemotherapy or neck dissection +/- adjuvant RT/chemoradiotherapy (CRT). We compared these strategies and identified prognostic factors. METHODS: From 1993 to 2015, 75 patients with SCC of unknown primary had RT-based or surgery-based treatment. Primary endpoints were overall survival (OS) and disease-free survival (DFS). Event-time distributions were estimated using the Kaplan-Meier method...

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...

Neuroendocrine neoplams (NENs) are mostly relatively indolent malignancies but a significant number have metastatic disease at diagnosis mainly to the liver. Although in the majority of such cases the primary origin of the tumor can be identified, in approximately 11-22% no primary tumor is found and such cases are designated as NENs of unknown primary origin (UPO). This has significant therapeutic implications with respect to potentially resectable hepatic disease and/or application of appropriate medical therapy, either chemotherapeutic agents or targeted treatment, as the response to various treatments varies according to the origin of the primary tumor...

BACKGROUND: Establishing the cancer type and site of origin is important in determining the most appropriate course of treatment for cancer patients. Patients with cancer of unknown primary, where the site of origin cannot be established from an examination of the metastatic cancer cells, typically have poor survival. Here, we evaluate the potential and limitations of utilising gene alteration data from tumour DNA to identify cancer types. METHODS: Using sequenced tumour DNA downloaded via the cBioPortal for Cancer Genomics, we collected the presence or absence of calls for gene alterations for 6640 tumour samples spanning 28 cancer types, as predictive features...

Treatment of patients with neck lymph node metastasis of squamous cell carcinoma (SCC) from unknown primary tumor (NSCCUP) is challenging due to the risk of missing occult tumors or inducing toxicity to unaffected sites. Human papillomavirus (HPV) is a promising biomarker given its causal link to oropharyngeal SCC and superior survival of patients with HPV-driven oropharyngeal SCC and NSCCUP. Identification of HPV-driven NSCCUP could focus diagnostic work-up and treatment on the oropharynx. For the first time, we assessed HPV antibodies and their prognostic value in NSCCUP patients...

Background: The incidence of human papillomavirus- (HPV-) related oropharyngeal squamous cell carcinoma (OPSCC) has been rapidly increasing worldwide. HPV is reported in approximately 50% cases of OPSCC in Japan. However, there are few reports of synchronous bilateral HPV-positive tonsillar carcinoma, and, in almost all those cases, carcinoma was detected using positron emission tomography/computed tomography and/or bilateral tonsillectomy. Methods and Results: We report the case of a 63-year-old male with bilateral tonsillar carcinoma detected using transoral endoscopic examination with narrow-band imaging (NBI)...

BACKGROUND: Cancer stem cells (CSCs) are considered to be the major factor in tumor initiation, progression, metastasis, recurrence and chemoresistance. Maintaining the stemness and promoting differentiation of these cells involve various factors. Recently, long non-coding RNAs (lncRNAs) have been identified as new regulatory factors in human cancer cells. However, the function of lncRNAs in colon CSCs is still unknown. METHODS: Primary colon cancer cells were maintained in serum-free medium to form spheres and CD133+/CD166+/CD44+ spheroid cells were selected using FACS technique...
