  • Swyer-James syndrome is a rare disease with patients presenting with unilateral hyperlucent lungs and hypoperfusion due to hypoplasia of the pulmonary artery and bronchiolitis obliterans. A unilateral hyperlucent lung generally develops after a lower respiratory tract infection during early childhood. In extremely rare cases, an association of bronchogenic carcinoma with Swyer-James syndrome has been reported. We report a case of bronchogenic squamous cell carcinoma associated with Swyer-James syndrome that performed right upper lobectomy and lymph node dissection with a relevant literature review.

  • 방광종양은 비뇨기 영역에서 가장 빈번히 발생하는 종양이며 그의 대부분은 이행 상피세포암이다. 요로상피세포암은 왜 상피세포내암ㆍ표재성암ㆍ침윤성암 등의 서로 다른 형태를 나타내는지, 또 암이 부분적으로 계속 존재할 것인지 또는 전신으로 퍼져나갈 것인지 예상을 하지 못하고 있다.

  • Immunohistochemical staining for keratin proteins may be useful as a diagnostic parameter in head and neck neoplasm. Our study evaluates the keratin antibody staining properties of normal tissues and squamous cell carcinoma of the vocal folds from surgical procedures performed on 27 cases. In normal epithelia, low molecular weight cytokeratins were strongly positive in basal layer but apparently reduced in suprabasal layers and completely negative in superficial layer. In invasive squamous cell carcinomas, low molecular weight anti-ck Ab were positive in all carcinoma cells of poorly differentiated carcinomas. On the other hand, high molecular weight anti-ck Ab were positive in almost carcinoma cells of well differentiated carcinomas.

  • Medicinal plants with synergistic effects on growth inhibition of canter cells under oxidative stress were screened in this study. Methanol extracts from 51 natural medicinal plants which were reported to have anticancer effort on hepatoma stomach cancer or colon cancers which are frequently found in Korean, were prepared and screened for their synergistic activity on growth inhibition of cancer cells under chemically-induced oxidative stress by using MTT assay. Twenty seven samples showed synergistic activity on the growth inhibition in various extent under chemically-induced oxidative stress. Among those samples, eleven samples such as Melia azedarach, Agastache rugosa, Catalpa ovata, Prunus persica, Sinomenium acutum Pulsatilla koreana, Oldenlandia diffusa, Anthriscus sylvestris, Schizandra chinensis, Gieditsia sinensis, Cridium officinale, showed decrease in $IC_{50}$ values more than 50%, other 16 samples showed decrease in $IC_{50}$ values between 50-25%, compared with the value acquired when medicinal plant sample was used alone. Among those 11 samples, extract of Catalpa ovata showed the highest activity. $IC_{50}$ values were decrease to 61% and 28% when carcinoma cells were treated with Catalpa ovata extract in combination of 75 and 100 uM of hydrogen peroxide, respectively.

  • Basalold squamous carcinoma (BSC) is a rare, aggressive neoplasm of the upper aerodigestive tract or esophagus. It is characterized by a biphasic pattern in which basaloid tumor is intimately associated with a neoplastic squamous component which can be either Invasive r in situ. Despite its characteristic histologic appearance, the BSC of the esophagus has been confused with esophageal neoplasm variously reported as adenoid cystic carcinoma or carcinoma with adenoid cystic differentiation Their distinction is important because genuine adenoid cystic carcinoma is much less as- gressive than BSC. The biologic course of BSC is similar to that of the more frequent squamous cell carcinoma of the esophagus. We have experienced a case of BSC of the esophagus in a 60-year-old male patient. The lesion was located in the middle third of the esophagus. The patient was treated with surgery followed by radio- therapy.

  • Background: Cytokeratin 19 is 40KD acidic molecule whose distribution is restricted to simple or pseudo-stratified epithelia, such as the epithelial layer of the bronchial tree. Immunohistochemical study have shown that cytokeratin 19 is overexpressed in lung carcinoma tissue. An immunoradiometric assay, CYFRA 21-1 has been developed using two monoclonal antibody, BM 19-21 and KS 19-1, reactive to different epitopes on cytokeratin 19. We studied the diagnostic value of CYFRA 21-1 in lung cancer. Method: The serum CYFRA 21-1 level using immunoradiometric kit(ELSA-CYFRA 21-1) was measured in 54 patients who admit to Yeungnam University Hospital from April, 1993 to August, 1994. Lung cancer group was 39 primary lung cancer patients(19 patients with squamous cell carcinoma, 11 patients with adenocarcinoma and 9 patients with small cell carcinoma). Control group was 15 patients with non malignant lung diseases(8 patients with pulmonary tuberculosis, 3 patients with chronic obstructive pulmonary disease, 2 patients with pneumonia and 2 patients with chronic obstructive pulmonary disease combined with pulmonary tuberculosis). Results: The mean serum value of CYFRA 21-1 was $20.2{\pm}4.7ng/ml$ in squamous cell carcinoma, $7.2{\pm}1.6ng/ml$ in adenocarcinoma and $15.5{\pm}4.7ng/ml$ in non-small cell lung cancer. The serum value of CYFRA 21-1 in control group was $1.7{\pm}0.5ng/ml$. All of the serum values of 3 histologic types were significantly higher than that of control group(p<0.01). The serum value of CYFRA 21-1 of squamous cell carcinoma was significantly higher than that of adenocarcinoma(p <0.05). Serum value of CYFRA 21-1 in small cell lung cancer was $2.9{\pm}0.9ng/ml$ and not significantly different compared with control group. Using cut off value of 3.3ng/ml, sensitivity and specificity was 11.1%, 65.2% in small cell lung cancer, 70.0%, 62.5% in non-small cell lung cancer, 73.7%, 75% in squamous cell carcinoma and 63.6%, 78.9% in adenocarcinoma, respectively. Conclusion: The serum levels of CYFRA 21-1 may be useful in diagnosis of non-small cell lung carcinoma, especially in squamous cell carcinoma with its high specificity.
