Curcumol is a sesquiterpene originally isolated from curcuma rhizomes, a component of herbal remedies commonly used in oriental medicine. Its beneficial pharmacological activities have attract significant interest recently. In this study, anti-cancer activity of curcumol was examined with both in vitro and in vivo models. It was found that curcumol exhibited time- and concentration-dependent anti-proliferative effects in SPC-A-1 human lung adenocarcinoma cells with cell cycle arrest in the G0/G1 phase while apoptosis-induction was also confirmed with flow cytometry and morphological analyses. Interestingly, curcumol did not display growth inhibition in MRC-5 human embryonic lung fibroblasts, suggesting the anti-proliferative effects of curcumol were specific to cancer cells. Anti-neoplastic effects of curcumol were also confirmed in tumor bearing mice. Curcumol (60 mg/ kg daily) significantly reduced tumor size without causing notable toxicity. In conclusion, curcumol appears a favorable anti-cancer candidate for further development.

Alpha-fetoprotein(AFP) is a plasma protein produced in the fetal liver, yolk sac and gastrointestinal tract. The plasma level of AFP decreases markedly 1 year after birth. The AFP level is usually increased in hepatocellular carcinoma and yolk sac tumor but is rare in a primary lung cancer. We report a case of primary adenocarcinoma of lung producing high levels of AFP.

The lung is one of the most frequent sites of metastasis for extrathoracic tumors. Certain malignancies show a particular tendency to metastasize to lung, and in 15 to 25% of these cases, lung involvement is the only manifestation of metastatic disease. The most common presentation is the form of multiple bilateral nodules or masses of varying sizes. Lymphangitic metastasis is comprising 6 to 8% of all pulmonary metastasis. A striking variant of parenchymal involvement occures when dyscohesive tumor cells fill alveoli to produce a tumoral pneumonia. Carcinomatous lymphangitis of prostate origin is infrequent and usually carries a poor prognosis, and tumoral pneumonia of it is extremely rare. We report herein a case of prostate carcinoma metastasizing to lung, simulates atypical pneumonia, and disclosed by acute chest illness.

Paraneoplastic limbic encephalitis is a rare disorder that is characterized by personality changes, irritability, depression, seizures, memory loss and dementia, and is commonly associated with small cell lung cancer. The cause is unknown but it is believed to be an autoimmune disorder that develops secondary to a carcinomatous process. We report a patient with the clinical feature consistent with limbic encephalitis. A 64-year-old women developed disorientation, memory loss and general weakness. She was diagnosed with NSCLC (adenocarcinoma) with a brain metastasis 1 year earlier and was treated with radiation and chemotherapy. Although the lung mass and brain metastatic lesions had improved, the brain T2-weighted MRI showed high signal intensity in the right temporal region. This lesion consisted of with limbic encephalitis and was negative to the other viral and immune markers. The patient's symptoms did not improve after steroid treatment. Our case demonstrated that a NSCLC (adenocarcinoma) also can be associated with paraneoplastic limbic encephalitis.

Trace elements are important components in the biological system, as a structural material and metabolic controller. Neutron activation analysis (NAA) with high neutron flux and high energy resolution Ge (Li) detector coupled to multichannel analyzer (MCA) has been one of the most accurate method for the determination of ultra-trace level components, and is applicable to biological material. In human body, the NAA can be used for quantitation of trace elements in various organs and tissue with endocrinological and metabolic disease and industrial metal poisoning. In this study, Triga Mark III nuclear reactor in Korea Atomic Research Institute was used for quantitation of trace eleement in human lung cancer tissues by neutron activation analysis. In the squamous cell carcinoma tissues, Br, Hg, La, Sb, Sc, Cl, Fe and I content were lower than normal lung tissues, and K, Rb and Se content were higher. In the adenocarcinoma tissues, Fe, Au, La, Sc and Zn content were lower than normal lung tissues, and Rb, Co and Se content were higher. Rb content was higher in the adenocarcinoma tissues than in the squamous cell carcinoma tissues. Fe and Na content were higher in the squamous cell carcinoma tissues than in the adenocarcinoma tissues.

Background: Adenocarcinoma (ADC) is the most common histological type of lung cancer and its proportion is rising, especially in Asian non-smoking women. Recent studies suggest miR-25 may have diverse effects on the pathogenesis of different types of cancer. However, the role of miR-25 in lung cancer is still unknown. The aim of this study was to investigate the potential clinical value of miR-25 in non-smoking women with lung ADC. Patients and Methods: Quantitative RT-PCR was performed to evaluate the expression of miR-25 in 100 lung ADC tumor tissues and matched plasma samples and Pearson correlation tests were used to analyze the relationship between values. Associations of miR-25 expression with clinicopathological features were determined using the Student's t-test. To determine prognostic value, overall survival (OS) was evaluated using the Kaplan-Meier method. Univariate and multivariate analyses were performed using the Cox proportional hazard model. Results: Expression of miR-25 in tissue was found to be associated with lymph node metastasis (P=0.021) and disease stage (P=0.012). Moreover, high miR-25 expression was also associated with poorer overall survival of women with lung ADC (P=0.008). Conclusion: Tissue miR-25 expression may be associated with tumor progression and have prognostic implications in female lung ADC patients.

Background: Lung cancer is the most common cause of cancer-related death worldwide. The incidence of lung cancer is aproximately 7-8 thousand percent in Turkish women. In this study, we aimed to evaluate the clinical, pathological properties and survival data of female patients with lung cancer who were treated in our center. Materials and Methods: From 2007 to 2012, 50 women with lung cancer were enrolled. Patient data were evaluated retrospectively. Results: The median age was 61 (40-81). Forty patients (80%) were diagnosed with non small cell lung cancer (NSCLC), 10 patients (20%) were small cell carcinoma (SCC). Twelve (24%) patients were smokers and 13 of 16 non-smokers had a history of exposure to asbestos. The most common histologic subtype was adenocarcinoma (46%) and this accounted for 71% in patients with exposure to asbestos. The most common initial Eastern Cooperative Oncology Group (ECOG) performance score was 1 (24 patients, 48%) and initial stage was IV (25 patients, 50%) in the study group. During the median 15 months (1-96 months) followup period: 1 year overall survival (OS) was 68%, 2year overall survival was 36% and the median survival time was 19 months. According to univariate analysis, poor ECOG performance status, advanced stage, anemia and weight loss at time of diagnosis were negative prognostic factors. However, adenocarcinoma sub-type was a positive prognostic factor. Conclusions: In this study NSCLC sub-type, poor ECOG performance score, advanced stage, anemia and weight loss were prognostic factors in Turkish women with lung cancer.

The purpose of this study is to report and demonstrate the effect of Korean medical treatment on a wedge resection of a lung patient with mucinous adenocarcinoma. The patient was an 84-year-old female who was diagnosed with mucinous adenocarcinoma and underwent wedge resection. The patient was treated with acupuncture and herbal medicine (Banhahubak-tang and Gamiondam-tang). The EORTC Quality of Life Questionnaire, Core 30 (EORTC QLQ-C30), EORTC Quality of Life Questionnaire, Lung Cancer 13 (EORTC QLQ-LC13), numeric rating scale (NRS), and the Global Assessment (G/A) were used to assess the changes in symptoms, including operation site pain and dyspnea. After treatment, the patient showed improvement in operation site pain and dyspnea, based on the NRS and G/A. However, dyspnea and pain were aggravated based on the EORTC QLQ-C30 and EORTC QLQ-LC13. Therefore, Korean medicine may have a substantial benefit for patients with mucinous adenocarcinoma after wedge resection of the lung.

Background: The purpose of this study was to determine the prognostic significance of the maximum standardized uptake value (SUVmax) on F-18-fluorodeoxyglucose (FDG)-positron emission tomography (PET) in patients undergoing surgical treatment for non-small cell lung cancer. Materials and Methods: Seventy-eight consecutive patients (58 with adenocarcinomas, 20 with squamous cell carcinomas) treated with potentially curative surgery were retrospectively reviewed. Results: The SUVmax was significantly higher in the patients with recurrent than with non-recurrent adenocarcinoma (p<0.01). However, among the patients with squamous cell carcinoma, there were no differences with or without recurrence (p=0.69). Multivariate analysis indicated that the SUVmax of adenocarcinoma lesions was a significant predictor of disease-free survival (p=0.04). In addition, an SUVmax of 6.19, the cut-off point based on ROC curve analysis of the patients with pathological IB or more advanced stage adenocarcinomas, was found to be a significant predictor of disease-free survival (p<0.01). Conclusions: SUVmax is a useful predictor of disease-free survival in patients with resected adenocarcinoma, but not squamous cell carcinoma. Patients with adenocarcinoma exhibiting an SUVmax above 6.19 are candidates for more intensive adjuvant therapy.

Most common metastatic tumors of the thyroid gland are squamous cell carcinoma of head and neck region, adenocarcinoma of breast and lung, malignant melanoma, and renal cell carcinoma of kidney in order of frequency. Metastasis from gastrointestinal tract to the thyroid gland rarely occurs. We experienced a case of fine needle aspiraton cytology of metastatic adenocarcinoma of both thyroid glands from the colon. Cytologic smears showed picket-fence like arrangement of nuclei of carcinoma cells and syncytial type of tissue fragments with acinar pattern on necrotic or mucoid background.
