The lung cancer in patients under 40 years old is rare and reported to be more rapidly fatal than in older persons. We reviewed the records of 18 cases who younger than 40 years with histologically proven lung cancer between 1959 and 1992 at department of Thoracic Surgery in National Medical Center. There were 12 male and 6 female patients. Two male and all female patients had never smoked. The 17 cases had respiratory symptoms for a mean duration of 3 months. The squamous carcinoma was found in 7 cases[38.9%], small cell carcinoma in 4 cases[22.2%], mixed cell carcinoma in 4 cases[22.2%], adenocarcinoma in 2 cases[11.1%] and bronchoalveolar cell carcinoma in 1 case. Among the 6 resected tumors, one case was stage I, two cases were stage II and three cases were stage IIIa. The operation was considered complete and curative in 6 patients and noncurative in 6 pations because of an exploratory thoracotomy. We conclude that lung cancer in young persons is virulent and that diagnosis is frequently delayed.

Objective : In this study, the medicine herbs above were directly treated to cultured normal lung cells and lung carcinoma cells, and the effects were investigated to develope new cancer treatments with increased anti-cancer efficiency as well as decreased side-effects and to suggest more useful clinical therapies. Materials and Methods : In the experiment, WI-26 VA lung normal cell line and A-427 lung carcinoma cell line were cultured. To observe the morphological change of the treated cells, were subjected to Giemsa staining and observed under Reflected Fluorescence microscope. To examine whether cell death occurred, cells observed under Reflected Fluorescence microscope, To investigate the degree of cell death in the nucleus, cells were screened by Laser cytometry ACAS 570. Results : Samgibopye-tang(Shenqibufei-tang) stimulated not only the growth of the normal cells but also that of the carcinoma cells, Wikyeung-tang(Weijing-tang) induced morphological change such as cytoplasmic constriction in the normal cells and the carcinoma cells, but it did not show any strong inhibitory effect on the cell growth. Samso-eum(Shensu-yin) caused severe cell damage in both cell lines, Eunkyo San(Yinqiao-san) significantly damaged the nuclei and caused weak cytoplasmic constriction in both cell lines, Normal cells treated with Gilgyeung-tang(Jingeng-tang) did not show any significant morphological change while some Gilgyeung-tang(Jingeng-tang) treated carcinoma cells were observed to have a normal cell-like shape, interestingly, conclusions : As the results above, Samgibopye-tang(Shenqibufei-tang), Wikyeung-tang(Weijing-tang), and Gilgyeung-tang(Jingeng-tang) helped the growth of both cell lines, and especially Samgibopye-tang(Shenqibufei-tang) showed the best effect, However, Samso-eum(Shensuyin) and Eunkyo-san(Yinqiao-san) caused lethal damage in the normal cells and also showed strong toxicity in the carcinoma cells.

International Ass ciation for the Study of Lung Cancer(IASLC) recommended the following classification of small cell lung carcinoma(SCLC) : (1) Small cell carcinoma (2) Mixed small cell/large cell carcinoma (3) Combined small cell carcinoma. Combined small cell carcinomas contain a squamous cell carcinoma or adenocarcinoma component. The prognostic significance of these elements is not known, but since the frequency and extent of non-small cell elements are considerably greater in posttherapy and autopsy tissues, it is possible that the non-SCLC elements are more resistant to therapy than the SCLC cells. Metaplasia & dysplasia of the bronchial surface epithelium are frequently observed in the bronchial biopsy specimens that contain small cell carcinoma of the lung. We report a case of combined small cell carcinoma with squamous element associated with microinvasive squamous cell carcinoma of the bronchial surface epithelium in 68 year old male patient, stage was IIIa. The two lesion are not connected n serial sections.

During the period of 4 years from August 1975 to August 1979 one hundred and forty seven cases of lung cancer were seen at Paik Foundation Hospital in Seoul, Korea. Among these 147 cases, 104 patients had primary carcinoma of the lung and the remainder was metastatic carcinoma to the lung. Among these 104 primary carcinoma patients, 73 cases were proven histologically as primary carcinoma of the lung. There were three cases of alveolar cell carcinoma [Table 1 ]. This clinical observation is based on those 73 cases including three case reports of the alveolar cell carcinoma. 1. Peak incidence was observed in the 5th decade of life. Male to female ratio was 2 to 1 [Fig. 1]. 2. Pathological classifications were as follows: epidermoid carcinoma, 24 cases [32.9%]; undifferentiated carcinoma, 20 cases [27.4%]; adenocarcinoma, 15 cases [20.5%]; bronchioloalveolar carcinoma [5.5%] and positive cytology, 10 cases [13.7%] [Fig. 2]. 3. Evidence of inoperability was observed in 55 patients [75% of the 73 cases] [Table 3]. 4. Among those 73 cases, operability was evaluated in 18 patients or 25%. One patient refused operation and 17 patients [23.6%] were explored. In 11 [15%] out of 17 patients, thoracotomies were performed. Six cases were pneumonectomies and 5 cases were lobectomies or bilobectomies [Fig. 3]. 5. First case of alveolar cell carcinoma was a 46 year-old housewife complaining of cough and hemoptysis for one year. The plain chest X-ray and bronchogram showed characteristic pictures as Figures 4 and 5. A pneumonectomy was carried out. Histologically, a beautiful alveolar carcinoma consisted of the characteristic tall columnar epithelial cells, which were lining the alveolar spaces as seen in Figures 6, 7, 8, and 20. 6. In the second case of 41 year old male, predominant clinical feature was single, well defined mass in the right lower lobe [Fig. 10 and 11] on chest X-ray. Bilobectomized specimen showed fragile, soft and hard tissue containing mucoid secretions and focal yellowish necrosis with pigmentation on cut surface [Fig. 12]. Slides showed tumor cells lined up along the alveolar septa with papillary projections [Fig. 13 and 14]. 7. Third case of alveolar cell carcinoma was a 50-year-old housewife with hemoptysis. An outstanding clinical picture was a round to lobulated mass in the right upper lobe [Fig. 16]. She is living now, 2 years and 1 month post-operatively, but has arrived at terminal stage with military nodular disseminations to the contralateral lung [Fig. 19].

SCY1-like 1-binding protein 1 (SCYL1BP1) is a newly identified transcriptional activator domain containing protein with many unknown biological functions. Recently emerging evidence has revealed that it is a novel regulator of the p53 pathway, which is very important for the development of human cancer. However, the effects of SCYL1BP1 on human lung squamous carcinoma cell biological behavior remain poorly understood. In this study, we present evidence that SCYL1BP1 can promote the degradation of MDM2 protein and further inhibit the G1/S transition of lung squamous carcinoma cell lines. Functional assays found that reintroduction of SCYL1BP1 into lung squamous carcinoma cell lines significantly inhibited cell proliferation, migration, invasion and tumor formation in nude mice, suggesting strong tumor suppressive function of SCYL1BP1 in lung squamous carcinoma. Taken together, our data suggest that the interaction of SCYL1BP1/MDM2 could accelerate MDM2 degradation, and may function as an important tumor suppressor in lung squamous carcinomas.

The mucoepidermoid carcinoma is a rare tumor in the lung. A case of bronchial mucoepidermoid carcinoma diagnosed by fine needle aspiration cytology is presented. The smear showed many intermediate cells with occasional mucus-secreting cells. Malignant squamous cells were not present. The cellular arrangement of intermediate cells was overlapping and grouped in ball-like fashion. These cytologic features are unique for diagnosis of this tumor.

The mucoepidermoid carcinoma is a rare tumor in the lung for less than 1% of all pulmonary neoplasm. It is mostly presented as a solitary pulmonary nodule at a large bronchial tree on bronchoscope. But more peripheral located tumor that not accessible to the bronchoscope are rarely reported on literature. The cytologic findings of these tumors are discribed as a mixture of squamous cells, mucous cells, and intermediate cells with overlapped cellular clusters. We experienced a case of peripheral mucoepidermoid carcinoma of lung diagnosed by fine needle aspiration cytology. The smear showed many cellular clusters on mucoid background. They consisted of many intermediate cells with occasional mucus-secreting cells, but malignant squamous cells were not present.

Objectives : We studied Effect of Platycodon grandiflorum on Lung carcinoma Methods : By using cDNA microarray technique, we analyzed the effects of AEPG(aqueous extract of Platycodon grandiflorum) on the gene expression profile. Results : Out of 384 genes screened associated with growth inhibition of carcinoma cell, 9 genes were founded to be affected in their expression levels by more than 1.2-fold after treatment with AEPG. And 67 genes were changed the expression level 0.5 times more than that of reference RNA after treatment of AEPG. Conclusions: These findings suggest that P. grandiflorum has strong potential for development as an agent for prevention and treatment against human lung cancer.
