  • Metastatic tumors to the eyes are probably the most common type of intraocular malignancies. The most common metastatic tumor is the breast cancer overall and lung cancer in men. An eyeball metastasis from lung cancer has a poor prognosis. Differentiating an eyeball metastasis from the primary malignant melanoma is important. Eyeball metastasis of a lung adenocarcinoma confirmed by pathology has not reported in Korea. Here we report a case of a metastatic lung adenocarcinoma to the eyeball confirmed by enucleation and a transbronchial lung biopsy with a review of the relevant literature.

  • Background : Thyroid Transcription Factor-1(TTF-1) acts as a tissue specific transcription factor in the regulation of lung specific gene expression and as morphogenic protein during lung organogenesis. Currently, there is very little information on the cis-acting sequences and transcription factors that direct the TTF-1 gene expression. DNAse 1 hypersensitive (DH) sites represent a marker for active or potentially active chromatin and are likely to be especially important in gene regulation, being associated with many DNA sequences that regulate gene expression. It is clear that DH regions correlate with genetic regulatory loci and binding for sequence-specific DNA-binding proteins. Methods : We have used DH site assays to identify putative distal regulatory elements in H441 lung adenocarcinoma cells, which express the TTF-1 gene and HeLa cells. Results : There are four DH sites 5' of the TTF-1 gene. These sites are located at base pair approximately +150, -450, -800, and -1500 from the start of transcription. Conclusion : These data suggest that there may be at least one intragenic site and regulatory region 5' prime to the promotor region.

  • A 23-year old woman was admitted to our hospital with hemoptysis. The chest X-ray showed reticulonodular opacity and multiple cysts throughout the entire lung field. The chest CT scan revealed numerous bilateral cysts with various sizes, some of them with thickened walls. An open lung wedge resection was performed. The resected specimen showed scattered small nodules, 0.3 to 0.6 cm in size. Microscopically, each nodule was composed of atypical glands with an occasional papillary architecture spreading to the alveolar septa, which were morphologically consistent with a papillary adenocarcinoma with a bronchioloalveolar carcinoma growth pattern. Immunochemically, the tumor cells were negative for the S-100 protein. The patient was diagnosed with an adenocarcinoma of the lung. A variety of diseases can produce or mimic multiple, thin-walled cysts in the lung. Lung cancer with multiple cysts is quite rare. Nevertheless, adenocarcinoma should be a diagnostic consideration. We report a case of a multiple cystic adenocarcinoma of the lung.

  • Idiopathic pulmonary fibrosis (IPF) is strongly associated with lung cancer compared with the general population. However, other types of idiopathic interstitial pneumonia (IIP) are rarely associated with lung cancer. We describe a case of a primary lung cancer associated with IIP other than IPF, which was considered to be nonspecific interstitial pneumonia (NSIP), and NSIP disappeared spontaneously after treating the primary lung cancer.

  • Background : Tumor size in lung cancer is not as good a prognostic factor for adenocarcinoma as it is for other types of lung cancer; therefore it is difficult to estimate the prognosis preoperative. However, there have recently been some reports on the radiologic findings correlating to the clinicopathologic prognostic factors in peripheral small adenocarcinoma of lung. We tried to evaluate the prognostic importance of High-Resolution CT (HRCT) findings of such adenoearcinoma, Material and Method: One houndred and seventy-six surgically resected small peripheral adenocarcinoma measuring 3 cm or less in greatest dimension were reviewed radiologically and clinicopathologically. Result: The patients with greater extent of ground-glass attenuation (GGA) had better clinico-pathological factors. The tumors with gross appearance of GGA or bubble-like shape showed better clinicopathological prognostic factors than scar-like or solid shape. Conclusion: HRCT findings of small peripheral adenocarcinomas of the lung correlated well with the histologic and clinical prognostic factors. We can predict the post-operative prognosis with the radiologic findings.

  • Bone metastases represent an important and frequent clinical problem in patients with advanced cancers. Especially, painful bone metastases are common features in these patients. Radiotherapy is an effective tool for palliative aim of painful metastatic osseous lesions. Various treatment results have been previously reported. The present retrospective study was aimed to evaluate the efficacy of palliative irradiation on pain relief, with the goal of selecting appropriate irradiation dose schedule. Radiotherapy consisted of 5times a week with a various fractional dose between 180 and 400cGy. The response of pain relief and the survival time after completion of radiotherapy are related to total dose and most of the patients have shown a similar response by the end of radiotherapy. The higher dose and the more aggressive multimodality treatment, the better pain control and the longer survival time.

  • Background : This study was designed to examine how glutathione, one of the nucleophilic sulfur compounds, effects the cisplatin cellular toxicity in the non-small cell lung cancer cell lines and normal lung epithelial cell line. Materials and Methods : Three cultured cell lines, the lung adenocarcinoma cell(NCL-H23), the lung squamous carcinoma cell(SK-MES-1) and the normal lung epithelial cell(L-132) line were exposed to various concentrations of cisplatin with or without glutathione. The relative viability was estimated as a means of measuring the cisplatin cellular toxicity using the MTT method. Results : In NCI-23, the response to cisplatin was sensitive but glutathione markedly increased the relative survival of the tumor cells by removing the antitumor effect of cisplatin. In both SK-MES-1 and L-132, the responses to cisplatin were less sensitive, and the chemoprotective effect of glutathione compared to and equal cisplatin dose was significantly higher in L-132 than in SK-MES-1(p<0.05). Conclusion : The protective effectes of of glutathione on cisplatin-induced cellular toxicity is more significant in normal lung epithelial cells than in squamous carcinoma cells.

  • Cystic lesions or progressive cystic changes in adenocarcinoma of the lung have rarely been reported. We report a case of lung adenocarcinoma that progressed from ground-glass opacities (GGOs) and consolidations or nodules to extensive cystic lesions during 12 months in a young adult patient. A 29-year-old male was initially diagnosed with primary lung adenocarcinoma by transbronchial lung biopsy of the right lower lobe and lung to lung metastasis in both lungs according to imaging findings. The initial chest computed tomography (CT) scans showed multifocal GGOs, consolidations, and nodules in both lungs. Despite treatment with palliative chemotherapy, the patient's follow-up CT scans showed multiple, cystic changes in both lungs and that the lesions had progressed more extensively. He died of hypoxic respiratory failure one year after his diagnosis.

  • It is difficult to distinguish a lung cancer from a pulmonary tuberculoma or other benign nodule. It is even more difficult to identify the type of lesion if the mass shows no change in size or demonstrates slow growth. Only a pathological confirmation can possibly reveal the nature of the lesion. A 61-year-old-woman was referred for a solitary pulmonary nodule. The nodule showed no change in size for the first two years and continued to grow slowly. Pathological and immunological analyses were conducted for confirmation of the nodule. The nodule was identified as a well-differentiated primary pulmonary adenocarcinoma. An LULobectomy was performed, and the post surgical stage of the nodule was IIIA (T2N2M0). Even though there are few risk factors, there is still the possibility of a malignancy in cases of non-growing or slow growing solitary pulmonary nodules. Therefore, pathological confirmation is encouraged to obtain a firm diagnosis.

  • Background: The incidence of adenocarcinoma of the lung has been increasing worldwide, and it has been generally been accepted to be relatively unrelated to smoking with a female preponderance. The aim of this study was to examine the gender-related pathological and survival differences in patients with an adenocarcinoma of the lung. Material and Method: A retrospective review of the clinical information of patients diagnosed with an adenocarcinoma of the lung at Kosin Medical Center from January 1999 to September 2005 was performed. The patient's demographics (age, gender), smoking history, stage, serum tumor marker, pathology classification, EGFR mutation, K-ras mutation, treatment methods, and survival time were analyzed. Result: Of the 438 patients, 179 (40.9%) were female. The median age at the diagnosis was 58 years for females and 59 years for males. However, 25.8% of women and only 17.7% of men were under 50 years of age (p=0.02). The distribution of the disease stage was similar in both men and women. The bronchioloalveolar carcinoma component was diagnosed more often in women (11.2%) than in men (5.0%). The overall survival rate was higher in women than in men (p=0.01), and women had a superior therapeutic response to a combined treatment of surgery and chemotherapy. Conclusion: This study showed significant genders differences in terms of the smoking history, bronchioloalveolar carcinoma component, overall survival, and survival after combined treatment of surgery and chemotherapy. Therefore, gender differences should be considered when diagnosing and treating adenocarcinomas of the lung.
