Expectoration of tumor tissue is a rare presentation in patients with cancer. Thirty cases of various types of tumor, including primary or metastatic lung cancer, have been reported. Endobronchial metastases from various organs are most common, although 9 primary lung cancer cases have been described, including 4 squamous cell carcinomas, 2 bronchogenic carcinoids, one small cell lung carcinoma...

PURPOSE In a previous study, we found a hyaluronidase 3 (HYAL3) gene mutation in exon 2 at position 188 by genome sequencing in a lung squamous cell carcinoma patient. The mutation results in substitution of serine for alanine. The aim of the study was to screen the HYAL3 gene mutation in Chinese lung squamous cell carcinoma patients and explore the correlation between mutation of HYAL3 with cl...

Association between progressive systemic sclerosis (PSS) and lung malignancy is rare yet well recognised. In order of frequency bronchioloalveolar carcinoma (BAC) is most common followed by squamous cell carcinoma, oat cell carcinoma, anaplastic carcinoma of lung. We present a 55 year old non-smoker male patient with PSS, who presented to us with progressively increasing shortness of breath and...

Non–small-cell lung cancer (NSCLC) refers to any type of epithelial lung cancer other than small-cell lung cancer.1 The disease arises from epithelial cells of the lung, from the central bronchi to terminal alveoli. The histological type correlates with site of origin, reflecting the variation in respiratory tract epithelium by location. The most common types of NSCLC are adenocarcinoma, squamo...

abstract carcinoma of the vulva has commonly been recognized as a disease of postmenopausal women, but some cases have been reported in young women during pregnancy. medical records were reviewed for a patient with vulvar carcinoma diagnosed in pregnancy. using medline and cross references, pertinent articles were sought and reviewed. a 28-year-old afghan woman in her sixth pregnancy presented ...

Lung cancer is the second most commonly occurring non-cutaneous cancer in the United States with the highest mortality rate among both men and women. In this study, we utilized three lung cancer microarray datasets generated by previous researchers to identify differentially expressed genes, altered signaling pathways, and assess the involvement of Hedgehog (Hh) pathway. The three datasets cont...

UNLABELLED Although thallium-201 (201Tl) uptake is related to perfusion in many normal tissues, the biologic rationale for 201Tl uptake in tumors is uncertain. To determine if tumor uptake is related to cell proliferation, we correlated the relative retention of 201Tl in lung tumors with expression of Ki-67, an indicator of cell proliferation. METHODS Sixty patients with lung tumors, included...

AIMS To determine (1) the detection rate of primary carcinoma of the lung by serological assay of CEA (carcinoembryonic antigen); and (2) whether addition of seroassay of squamous cell carcinoma related antigen before treatment improves detection sensitivity. METHODS A prospective study spanning 27 months was conducted at the University Hospital, Kuala Lumpur. Serum CEA (Abbott IMx) and serum...

Immunohistochemical staining utilizing a peroxidase-antiperoxidase (PAP) technique for keratin, carcinoembryonic antigen (CEA), human chorionic gonadotropin (HCG) and alpha-fetoprotein (AFP) was performed on paraffin sections from 72 cases of lung cancer obtained at autopsy. Positive reaction was shown in 44% of the cases for keratin, 77% for CEA, and 58% for HCG. AFP was positive in only one c...

Medicinal plants have been investigated for possible anti-cancer effects. The aim of the present study was to examine the cytotoxic activity of several medicinal plants on different tumor cell lines. 11 selected plant species which have been used in folkloric prescriptions were collected from different sites of Hamedan district of Iran. The methanolic extracts of the plants were prepared and th...
