OBJECTIVES Although the chemokine CXCL12 and its receptor CXCR4 have been implicated in metastasis of non-small cell lung carcinoma, the prognostic significance of these molecules is poorly defined. This study aimed to determine whether expression of these molecules is associated with clinicopathologic features and disease-free survival in non-small cell(More)
Cervical/endocervical cytology screening has decreased morbidity and mortality, and implementing adjunctive human papilloma virus (HPV) DNA testing for atypical squamous cells of undetermined significance has improved the specificity for detecting premalignant squamous lesions. Currently, there are no guidelines to perform HPV DNA testing on(More)
Melanoma is an aggressive malignancy with a growing prevalence. Although early detection and excision offer a potential cure, recurrences and metastases are not uncommon. Fine-needle aspiration (FNA) can play a vital role in their detection as a relatively noninvasive, rapid, and economical alternative for tracking disease evolution. Prior clinical history(More)
BACKGROUND The purpose of the study was to assess the efficacy of obtaining adequate cytologic specimens by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for molecular testing of lung adenocarcinomas. METHODS This was an institutional review board-approved study of all patients who had undergone EBUS-TBNA from April 2010(More)
Duct carcinoma in situ (DCIS) is a malignant neoplasm of the breast that is limited to the glandular component. The introduction of mammographic screening allows for earlier detection of carcinoma, at the stage of DCIS, before it invades the surrounding stroma. Although DCIS has been studied extensively, its quantification remains a dilemma. Several methods(More)
CONTEXT Lung and breast carcinomas are among the most prevalent cancers. Advances in cancer therapies can provide survival benefit and be potentially curative, even in metastatic disease. Due to the high prevalence of these carcinomas, it is not unusual to encounter lung nodule(s) in a patient with breast carcinoma, and distinguishing between primary and(More)
Human papillomavirus (HPV) is recognized as a causal agent for cervical carcinomas. Assimilation of HPV oncogenes E6 and E7 into the host DNA promotes upregulation of cyclin dependent kinase inhibitor (CDKI) p16(INK4A), detectable by monoclonal antibody in the developing cervical cancer cells. The aim of this study was to 1) develop a protocol for(More)
Combined small cell lung carcinomas (CSCLCs) are small cell lung carcinomas (SCLCs) containing discrete areas of non-small cell morphologic components, found in up to 30% of SCLCs. We assessed immunophenotypic and genotypic similarity between the distinct morphologic constituents in 7 CSCLCs. Each was stained for synaptophysin, CD56, chromogranin, bcl-2,(More)
Dyspnea in a patient with cancer may have several causes, including infection, thromboembolism, metastases, and therapeutically induced cardiopulmonary disease. Pulmonary tumor embolism is an uncommon cause. Occlusion of the pulmonary microvasculature by tumor cells and associated thrombi can produce a subacute and progressive clinical picture that(More)
