Histological subtypes oral cancer

Daniel P Hollern, Matthew R Swiatnicki, Eran R Andrechek
Human breast cancer has been characterized by extensive transcriptional heterogeneity, with dominant patterns reflected in the intrinsic subtypes. Mouse models of breast cancer also have heterogeneous transcriptomes and we noted that specific histological subtypes were associated with particular subsets. We hypothesized that unique sets of genes define each tumor histological type across mouse models of breast cancer. Using mouse models that contained both gene expression data and expert pathologist classification of tumor histology on a sample by sample basis, we predicted and validated gene expression signatures for Papillary, EMT, Microacinar and other histological subtypes...

Diffuse Large B-Cell Lymphoma (DLBCL) is the most common histological subtype of Non-Hodgkin's Lymphoma (NHL). Primary retroperitoneal DLBCL is uncommon and has seldom been reported. Extrinsic compression of the duodenum due to lesions originating from the retroperitoneum is also rare. We present a case of a 39-year-old man who presented with inability to tolerate oral intake, abdominal pain, an upper abdominal mass and postprandial bilious vomiting caused by a large DLBCL arising from the retroperitoneum causing extrinsic compression of the duodenum...

BACKGROUND: Invasive lobular breast tumors display unique reproductive risk factor profiles. Lobular tumors are predominantly Luminal A subtype, and it is unclear whether reported risk factor associations are independent of molecular subtype. METHODS: Polytomous logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the associations between risk factors and histologic subtype [ductal (n = 2,856), lobular (n = 326), and mixed ductal-lobular (n = 473)] in the Carolina Breast Cancer Study (1993-2013)...

Myofibroblasts are differentiated contractile cells that can secrete extracellular matrix components, cytokines, proteases, and proangiogenic factors. In neoplastic processes such as oral squamous cell carcinoma (OSCC), myofibroblasts are recognized as cancer-associated fibroblasts (CAFs) and actively participate in tumor progression. As the presence of myofibroblasts in the stroma may be an important parameter of invasion and proliferation, the aim of this study was to evaluate the presence of CAFs in OSCC by immunophenotyping and their association with histologic classification and clinicopathologic parameters...

BACKGROUND: For many years, first-line treatment for locally advanced or metastatic soft-tissue sarcoma has been doxorubicin. This study compared gemcitabine and docetaxel versus doxorubicin as first-line treatment for advanced or metastatic soft-tissue sarcoma. METHODS: The GeDDiS trial was a randomised controlled phase 3 trial done in 24 UK hospitals and one Swiss Group for Clinical Cancer Research (SAKK) hospital. Eligible patients had histologically confirmed locally advanced or metastatic soft-tissue sarcoma of Trojani grade 2 or 3, disease progression before enrolment, and no previous chemotherapy for sarcoma or previous doxorubicin for any cancer...

OBJECTIVE: : Oral squamous-cell carcinoma (OSCC) accounts for >90% of oral cancers affecting adults mostly between the fourth to seventh decades of life. The most common OSCC treatment is concomitant chemoradiotherapy (CCRT) having both loco-regional and distant control, but CCRT has acute and chronic toxic effects on adjacent normal tissue. This study aimed to determine the side effects of CCRT on the oral mucosa and to characterize the clinicopathology of oral lesions in patients with OSCC...

Colon polyps represent precursor lesions of colon cancers and their malignant potential varies according to histological subtype. A rare subtype of colon polyps is the Peutz-Jeghers (PJ) polyp. PJ polyps mostly occur in the context of Peutz-Jeghers syndrome, which is characterized by the development of multiple polyps in the intestinal tract and hyperpigmentation of oral mucosa and lips. Peutz-Jeghers is an autosomal dominant disorder caused by pathogenic variants of the serine threonine kinase STK11. PJ polyps very rarely occur outside of the syndrome and are then referred to as solitary PJ polyps...

Patients with relapsed or refractory (R/R) non-Hodgkin lymphoma (NHL) have a poor prognosis and limited treatment options. We evaluated selinexor, an orally bioavailable, first-in-class inhibitor of the nuclear export protein XPO1, in this phase 1 trial to assess safety and determine a recommended phase 2 dose (RP2D). Seventy-nine patients with various NHL histologies, including diffuse large B-cell lymphoma, Richter's transformation, mantle cell lymphoma, follicular lymphoma, and chronic lymphocytic leukemia, were enrolled...

PURPOSE: Survival following ovarian cancer diagnosis is generally low; understanding factors related to prognosis could be important to optimize treatment. The role of previously diagnosed comorbidities and use of medications for those conditions in relation to prognosis for ovarian cancer patients has not been studied extensively, particularly according to histological subtype. METHODS: Using pooled data from fifteen studies participating in the Ovarian Cancer Association Consortium, we examined the associations between history of hypertension, heart disease, diabetes, and medications taken for these conditions and overall survival (OS) and progression-free survival (PFS) among patients diagnosed with invasive epithelial ovarian carcinoma...

BACKGROUND: Erlotinib is an EGFR tyrosine kinase inhibitor that has shown a significant but only marginally improved median overall survival when combined with gemcitabine in patients with locally advanced and metastatic pancreatic cancer. Vandetanib is a novel tyrosine kinase inhibitor of VEGFR2, RET, and EGFR, all of which are in involved in the pathogenesis of pancreatic cancer. We investigated the clinical efficacy of vandetanib when used in combination with gemcitabine in patients with advanced pancreatic cancer...

Patients suffering from advanced basal cell carcinoma (BCC) have very limited treatment options. Sonidegib selectively inhibits the growth of Hedgehog pathway-dependent tumors and can treat locally advanced BCC patients who are not candidates for surgery or radiation therapy. The BOLT clinical trials were conducted to evaluate the efficacy/potency of sonidegib in the treatment of advanced BCC or metastatic BCC. The patients were randomized in 1:2 ratios to receive 200 or 800 mg oral sonidegib daily, stratified by disease, histological subtype and geographical region...

Angiosarcomas are one of the rarest subtypes of sarcomas; those are malignant vascular tumors arising from vascular endothelial cells. Occurrence of intra-oral angiosarcoma is extremely rare (0.0077% of all cancers in Europe). We present here, to our knowledge, the first case of a 83-year-old man with gingival and both palatine tonsils localization of a grade-two angiosarcoma discovered after a two months history of a painful lesion followed by hematoma and spontaneous bleeding. Chemotherapy with paclitaxel and hemostatic radiotherapy were inefficient and he died seven months after the first symptoms...

Presently, there is no consensus regarding which chemotherapy regimen is best to administer with radiotherapy in patients with locally advanced non-small-cell lung cancer (LA-NSCLC). Herein, our aim was to compare the outcome of patients treated with either etoposide-cisplatin (EP) or docetaxel-cisplatin (DP) in this curative setting.Patients treated with either EP or DP and concurrent radiotherapy from 2004 to2012 were identified and their detailed medical records and follow-up information were obtained for analysis in this retrospective study...

PURPOSE: An understanding of the etiologic heterogeneity of ovarian cancer is important for improving prevention, early detection, and therapeutic approaches. We evaluated 14 hormonal, reproductive, and lifestyle factors by histologic subtype in the Ovarian Cancer Cohort Consortium (OC3). PATIENTS AND METHODS: Among 1.3 million women from 21 studies, 5,584 invasive epithelial ovarian cancers were identified (3,378 serous, 606 endometrioid, 331 mucinous, 269 clear cell, 1,000 other)...

BACKGROUND: Various subtypes of melanoma-associated antigens (MAGEs) are expressed in the tumor tissues of patients with head and neck squamous cell carcinoma (HNSCC). However, little data are currently available on how the gene expression of MAGEs impacts clinical patterns and oncologic outcomes. We have therefore evaluated the expression of MAGE-A1-6 (A1-6) subtypes in tumor tissues of patients with HNSCC and the clinical impact of this expression. METHODS: This was a retrospective review of 53 patients with histologically proven HNSCC of the oral cavity, oropharynx, larynx, or hypopharynx who underwent both treatment and analysis by reverse transcription (RT)-PCR assay with a common primer to identify the expression of MAGE-A1-6 subtypes in the tumor tissue...

CONTEXT: Introduction of trastuzumab, a recombinant monoclonal antibody against the extracellular domain of HER-2, is a cornerstone in the treatment of HER-2+ breast carcinoma. However, many cancers that have an initial response to trastuzumab will progress some time later. After progression on trastuzumab-based first-line treatment, there are several options. Although TDM-1 (Trastuzumab emtansine) has prolonged progression-free survival (PFS) and overall survival in patients previously treated with trastuzumab and taxane, it is still not available in Turkey...

Oral tongue squamous cell carcinoma (OTSCC) is the most common oral cancer subtype with a maximum propensity for regional spread. Our objective was to study if p53 expression might have any correlation with aggressive patterns of invasion within oral tongue cancers as well as with the histologically identified degree of oral tongue dysplasia. p53 immunoexpression was studied using immunohistochemistry in early staged OTSCCs (n=155), oral tongue dysplasias, (n=29) and oral tongue normal specimens (n=10) and evaluated for correlations with histological and clinicopathological parameters...

Non-melanoma skin cancer (NMSC) comprises basal cell carcinoma (BCC) and squamous cell carcinoma, together with a host of rare tumours. NMSC is the commonest malignancy among Caucasians and its incidence continues to rise annually. Exposure to UV radiation initiates approximately 90% of NMSC, causing malignant transformation of keratinocytes and suppression of the inflammatory response. Risk factors include sun exposure and immunosuppression. There are several subtypes of BCC, although histological overlap is common...
