OBJECTIVE: To examine the effect of diagnosis year, defined as contemporary (2010-2014), intermediate (2006-2009) and historical (2001-2005) on cancer-specific mortality (CSM) in patients with metastatic renal cell carcinoma (mRCC). METHODS: Within Surveillance, Epidemiology, and End Results registry (2001-2014), we identified patients with mRCC. Cumulative incidence and competing risks regression (CRR) models examined CSM, after accounting for other-cause mortality...

OBJECTIVE: To describe the course of disease of patients surgically treated for locally recurrent renal cell carcinoma (LRRCC) after nephrectomy and to identify potential predictive factors for long-term survival. PATIENTS AND METHODS: We, retrospectively, identified 54 patients who underwent surgical resection of LRRCC after open nephrectomy for localized kidney cancer. The median age at time of surgery for LRRCC was 65 years. Survival rates were determined with the Kaplan-Meier method...

A rat model of sarcomatoid mesothelioma, mimicking some of the worst clinical conditions encountered, was established to evaluate the therapeutic potential of intracavitary curcumin administration. The M5-T1 cell line, selected from a collection established from F344 rats induced with asbestos, produces tumors within three weeks, with extended metastasis in normal tissues, after intraperitoneal inoculation in syngeneic rats. The optimal concentration/time conditions for killing M5-T1 cells with curcumin were first determined in vitro...

The most comprehensive sequencing effort of sarcomatoid renal cell carcinoma (sRCC) to date reinforces the notion that the sarcomatoid component is closely related to the epithelial component of the cancer. This work also challenges the notion that sRCC evolves from low grade RCC and identifies potential mediators of sarcomatoid differentiation.

Objectives: Accurate diagnosis of malignant peripheral nerve sheath tumor (MPNST) is often challenging on fine-needle aspiration (FNA) or core needle biopsy. Recurrent mutations in EED and SUZ12, which encode subunits of polycomb repressive complex 2 (PRC2), have been identified in 70% to 92% of MPNSTs; PRC2 inactivation leads to loss of trimethylation of lysine 27 of histone H3 (H3K27me3). We evaluated the utility of H3K27me3 immunohistochemistry for distinguishing MPNST from its cytomorphologic mimics...

A 47-year-old male presented with haematuria and flank pain for two weeks. Ultrasonography and renal scan revealed a poorly functioning left kidney with multiple calculi. Simple nephrectomy was performed and the specimen revealed a mass in his renal pelvis which showed both carcinomatous and sarcomatous components on microscopy. The sarcomatous component consisted of diffuse pleomorphic osteoblasts with intervening lacy osteoid, giving an osteosarcoma-like appearance. These areas of tumour were strongly positive for vimentin and osteopontin...

OBJECTIVE/HYPOTHESIS: There are limited treatment options beyond surgical salvage for patients who fail nonoperative treatment for laryngeal squamous cell carcinoma. In this study, we examine the failure patterns after surgical salvage and the potential pathologic and clinical prognostic variables that might guide further postoperative intensification investigation. STUDY DESIGN: Retrospective analysis at a tertiary academic referral center. METHODS: From an institutional review board-approved institutional head and neck cancer registry, a consecutive series of 147 patients who underwent salvage laryngectomy for squamous cell cancer recurrence or persistence after radiotherapy with or without chemotherapy between May 1995 and May 2016 were identified...

With the objective of finding an avenue for development of magnetic hyperthermia as an effective mesothelioma treatment, the influence of heating by magnetite nanoparticles (MNPs) with a diameter of ~40nm, which were incorporated into cells and then subjected to AC magnetic field, on induction of cell death was investigated in all three histological subtypes of human mesothelioma cells (i.e., epithelioid NCI-H28, sarcomatoid NCI-H2052, and biphasic MSTO-211H cells). Cellular uptake of MNPs was observed in all cell types, but the amount of MNPs incorporated per cell into MSTO-211H cells was smaller than in NCI-H28 and NCI-H2052 cells...

OBJECTIVE: To understand urethral secondary malignancies among patients treated with brachytherapy (BRT) for primary prostate cancer. METHODS: Institutional retrospective review identified 13 patients evaluated from 2003-2014 with urethral cancer and prior history of BRT monotherapy for prostate cancer. All patients were biochemically free of their primary disease and developed histologically distinct RASM from primary tumor via pathologic confirmation. BRT characteristics, patient age, presentation, staging work-up and clinical course were evaluated...

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC), originally known as HPV-related carcinoma with adenoid cystic carcinoma-like features, is a peculiar neoplasm that is restricted to the sinonasal tract, exhibits features of both a surface-derived and salivary gland carcinoma (particularly adenoid cystic carcinoma), and is associated with high-risk HPV. Given the limited number of published cases, the full clinicopathologic spectrum of this neoplasm is unclear. Here, we present an updated experience of 49 cases...

BACKGROUND: Patients with sarcomatoid renal-cell carcinomas (sRCC) have poor outcomes and limited treatment options. Preclinical and clinical data suggest susceptibility to cytotoxic agents and vascular endothelial growth factor-targeted therapies. We designed a phase 2 trial to evaluate the efficacy and safety of capecitabine, gemcitabine, and bevacizumab in sRCC. PATIENTS AND METHODS: Patients with metastatic or unresectable sRCC were eligible for inclusion. Patients received oral capecitabine 800 mg/m(2) twice daily on days 1 to 21 of a 28-day cycle, intravenous gemcitabine 900 mg/m(2) on days 1 and 15, and intravenous bevacizumab 10 mg/kg on days 1 and 15...

AIMS: Renal cell carcinoma, unclassified (RCCU) is a category that includes a morphologically and biologically heterogeneous group of tumors that are unable to be diagnosed as other well-defined entities. We aim to describe the morphologic findings of tumors within this category and to determine the most frequent morphologic features leading to classification difficulty. METHODS AND RESULTS: One hundred and thirty-six cases of RCCU were examined. Patients ranged in age from 23 to 87 years...

BACKGROUND: The immune profile of sarcomatoid renal cell carcinoma (sRCC), including the programmed cell death ligand 1 (PD-L1) and programmed cell death 1 (PD-1) status, has not been well characterized. METHODS: An immunohistochemical digital analysis of PD-L1, PD-1, CD4, and CD8 was performed on nephrectomy specimens from 118 sRCC patients and 92 nonsarcomatoid clear cell renal cell carcinoma (ccRCC) patients. The clinical characteristics of the population were compared between sRCC and ccRCC...

The association of sarcomatoid carcinoma (SC) with small cell carcinoma (SCC) has not been systematically studied. We identified 39 consult cases between 2001-2016 with available slides for review in 28 cases. There were 19 men and 9 women [mean age: 78years (51-89)]. In 26 (92.8%) cases, the sarcomatoid component had nonspecific malignant spindle cells, 4 (14%) chondrosarcoma, 2 (7%) myxoid sarcomatous, 1 (3.5%) osteosarcoma, and 1 (3.5%) rhabdomyosarcoma. The predominant component was in 11 (39%) cases SCC, 6 (21%) urothelial carcinoma, 3 (10%) sarcomatoid, and 8 (29%) equal sarcomatoid and SCC...

BACKGROUND: Oral squamous cell carcinoma (OSCC) is usually diagnosed at an advanced stage and is commonly preceded by oral premalignant lesions. The mortality rates have remained unchanged (50% within 5 years after diagnosis), and it is related to tobacco smoking and alcohol intake. Novel molecular markers for early diagnosis are urgently needed. The purpose of this study was to evaluate the diagnostic value of methylation level in a set of 18 genes by bisulfite next-generation sequencing...

Diffuse malignant mesothelioma of the pleura is a highly aggressive tumor typically associated with short survival. ALCAM (CD166), a type I transmembrane protein, is a member of the immunoglobulin superfamily. In normal cells, ALCAM regulates physiological processes such as angiogenesis and immune response. In cancer, it is associated with neoplastic progression, including invasion, migration, and metastasis. Furthermore, ALCAM is considered one of the cancer stem cell markers such as ALDH1 (ALDH1A1) and SALL4...
