  • Paraneoplastic neurologic syndrome is a group of assorted disorders resulting from damage to the nervous system in cancer, remote from primary site, and not related to metastasis, infection, or metabolic disorder associated with cancer. Patient with small cell lung cancer sometimes shows various neurological syndromes, but patient with non-small cell lung cancer rarely shows neurologic syndromes and few antineuronal antibodies have been found. Here, we report a case of 53-year-old male patient who developed ptosis and extraocular muscular limitation of left eye due to third and forth cranial nerve palsy in non-small cell lung cancer without brain metastasis. These neurologic symptoms improved after lobectomy without any other treatment immunotherapy.

  • During the period of 10 years from July, 1976 to July, 1986, 154 cases of primary carcinoma of the lung - by the cell type, stage, operability, and survival rate in the resectable cases - are analyzed at the Dept. of Thoracic Surgery, Paik Hospital in Seoul. The results are as follows: 1] Histopathological types are squamous cell carcinoma 49% [76 cases], adenocarcinoma 25% [39 cases], undifferentiated large cell carcinoma 9% [14 cases], undifferentiated small cell carcinoma 6% [9 cases], bronchioloalveolar carcinoma 4% [6 cases] and adenosquamous carcinoma 3% [4 cases]. 2] Peak incidence is observed in the 4th decade of life [33%], then 5th [29%] and 3rd [21%] respectively. Male to female ratio is 4 to 1. 3] Evidence of inoperability is observed in 64% [99 cases] by clinical staging workup. Thirty six percent [55 cases] were operated. Of these, post-surgical stage I was 5% [3 cases], stage II, 64% [35 cases] and stage III, 31% [17 cases]. Among total 17 cases of stage III, 14 cases were unresectable with evidence of T2N2M0, while 3 cases were resectable. Resectability is 27%, [41 cases] from the total number of 154 cases. And the resectability for the ex 55 cases is 75% [41 cases]. 4] By cell type, highest resectabitity is the squamous cell carcinoma, 49% [20 cases]. Adenocarcinoma is 32% [13 cases] and bronchioloalveolar, 12% [5 cases]. 5] Survival rate is evaluated for 38 cases of 41 resectable stage I, II and III. Overall 5 year survival rate is 24%, 3 year 32% and 10 year 8%. Survival rate in stage II for 5 year is 25%. In squamous cell type for, 5 year is 42%. Authors believe when surgeons continuous effort of early detection is met with patients early visit, 5 year survival rate for the stage I K II resectable patients will improve more effectively. As well, When the efforts are added to combined modality with radiotherapy and chemotherapy for the stage III selected cases of non-small cell carcinoma patients, the enhancement in survival rate is expected.

  • Adenosquamous carcinoma of the lung is a rare disease entity and its clinical characteristics, treatment, and prognosis are poorly described. Stage I disease are amenable to operation as in bronchogenic carcinoma of non-small cell type, but stage III adenosquamous carcinoma shows highly aggressive behavior with rapid progression. We have experienced a case of stage III adenosquamous carcinoma of the lung in a 38-year-old male with a large mass in the right upper lobe with multiple metastasis in the mediastinal lymph nodes. Interestingly, all of the metastatic lymph nodes proved to be adenous component histologically. After right pneumonectomy and extensive lymph node dissection, the patient had received one cycle of chemotherapy. However, clinical signs of distant metastasis to bone and brain were discovered within 5 months postoperatively.

  • Locally advanced non-small cell lung cancer (LA-NSCLC) is composed of heterogeneous subgroups that require a multidisciplinary team approach in order to ensure optimal therapy for each patient. Since 2010, the National Comprehensive Cancer Network has recommended chemoradiation therapy (CRT) for bulky mediastinal disease and surgical combination for those patients with single-station N2 involvement who respond to neoadjuvant therapy. According to lung cancer tumor boards, thoracic surgeons make a decision on the resectability of the tumor, if it is determined to be unresectable, concurrent CRT (CCRT) is considered the next choice. However, the survival benefit of CCRT over sequential CRT or radiotherapy alone carries the risk of additional toxicity. Considering severe adverse events that may lead to death, fit patients who are able to tolerate CCRT must be identified by multidisciplinary tumor board. Decelerated approaches, such as sequential CRT or high-dose radiation alone may be a valuable alternative for patients who are not eligible for CCRT. As a new treatment strategy, investigators are interested in the application of the innovative radiation techniques, trimodality therapy combining surgery after high-dose definitive CCRT, and the combination of radiation with targeted or immunotherapy agents. The updated results and on-going studies are thoroughly reviewed in this article.

  • Objectives : This study was designed to investigate the antiproliferative activity of the water extract of Samgibopae-tang (SGBPT) in NCI-H460 and A549 non-small-cell lung cancer cell lines Methods : In this study, we measured the subsistence, form of NCI-H460 and A549 non-small-cell lung cancer cell by hemocytometer and DAPI staining. In each cell, we analyzed DNA fragmentation. reverse transcription-polymerase chain reaction and measured activity of caspase-3, caspase-8 and caspase-9. Results and Conclusions : We found that exposure of A549 cells to SGBPT resulted in growth inhibition in a dose-dependent manner. butSGBPT did not affect the growth of NCI-H460 cells. The antiproliferative effect by SGBPT treatment in A549 cells was associated with morphological changes. SGBPT treatment partially induced the expression of DR5 cells and the expression of Faswas markedly increased in both transcriptional and translational levels in A549 cells. SGBPT treatment partially induced the expression of Bcl-2, Bcl-XL and the expression of Bid was markedly decreased in translational levels in A549 cells. However, SGBPT treatment did not affect the expression of IAP family in A549 orNCI-H460 cells. SGBPT treatment partially induced the expression of caspase-3, caspase-8, caspase-9 activity which markedly increased in a dose-dependent manners in A549 cells. The fragmental development of PARP and ${\beta}$-catenin protein was observed in A549 cells by SGBPT treatment. SGBPT treatment induced the expression of PLC-${\gamma}1$ protein which decreased in A549 cells. SGBPT treatment partially induced the expression of DFF45/ICAD which markedly increased in a dose-dependent manner in A549 cells. Taken together. these findings suggested that SGBPT-induced inhibition of human lung carcinoma did not affect NCI-H460 cell growth. However, SGBPT-induced inhibition of human lung carcinoma A549 cell growth was associated with the induction of death receptor and mitochondrial pathway. The results provided important new insights into the possible molecular mechanisms of the anti-cancer activity of SGBPT.

  • Lymphoepithelioma-like carcinoma (LELC) of the lung is a very rare tumor. Originally described in the nasopharynx as lymphoepithelioma, this carcinoma has also been found in the stomach, esophagus, thymus, cervix, urinary bladder, skin, and salivary glands. Histologically, it is an undifferentiated carcinoma that has a syncytial appearance with tumor cells and is infiltrated by numerous lymphocytes, macrophages, and plasma cells. LELC of the lung occurs more commonly in Asians, particularly Chinese. Many studies have reported the association between Epstein-Barr virus (EBV) and LELC of the lung in Asian patients. A 45-year-old man had a solitary pulmonary nodule on a routine chest X-ray examination. As a malignant tumor was suspected, surgical resection was performed to establish the correct diagnosis. The pathology of the excised tumor demonstrated LELC of the lung. This is the first report of LELC of the lung in Korea.

  • Interferon-gamma (IFN-${\gamma}$) has been used to treat various malignant tumors. However, the molecular mechanisms underlying the direct anti-proliferative activity of IFN-${\gamma}$ are poorly understood. In the present study, we examined the in vitro antitumor activity of IFN-${\gamma}$ on two human non-small-cell lung carcinoma (NSCLC) cell lines, H322M and H226. Our findings indicated that IFN-${\gamma}$ treatment caused a time-dependent reduction in cell viability and induced apoptosis through a FADD-mediated caspase-8/tBid/mitochondria-dependent pathway in both cell lines. Notably, we also postulated that IFN-${\gamma}$ increased indoleamine 2,3-dioxygenase (IDO) expression and enzymatic activity in H322M and H226 cells. In addition, inhibition of IDO activity by the IDO inhibitor 1-MT or tryptophan significantly reduced IFN-${\gamma}$-induced apoptosis and death receptor 5 (DR5) expression, which suggests that IDO enzymatic activity plays an important role in the anti-NSCLC cancer effect of IFN-${\gamma}$. These results provide new mechanistic insights into interferon-${\gamma}$ antitumor activity and further support IFN-${\gamma}$ as a potential therapeutic adjuvant for the treatment of NCSLC.

  • Purpose: This study investigates the alterations in A549 human non-small-cell lung cancer (NSCLC) cells exposed to Citrus junos extract (CJE). We further examine the antiproliferative and apoptotic effects of CJE on NSCLC cells. Methods: Inhibition of proliferation was examined by applying the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) colorimetric assay on CJE-treated A549 NSCLC cells. The lactate dehydrogenase (LDH) assay was performed to measure the degree of toxicity of CJE on NSCLC cells. The effect on migratory proliferation was confirmed using the scratch wound healing assay. The antiproliferative effect of the CJE on human lung cancer cells was verified through morphological observation, fluorescence microscopy, and caspase-3 colorimetry. Results: Exposure of NSCLC cells to CJE resulted in a dose- and time-dependent decrease in cell activity and increased toxicity to the cells. In addition, microscopic observation revealed a reduced ability of the cancer cells to migrate and proliferate after exposure to the CJE, with simultaneous morphological apoptotic changes. Fluorescence staining and microscopic examination revealed that this death was a process of self-programmed cell death of NSCLC cells. Compared to unexposed NSCLC cells, the expression of caspase-3 was significantly increased in cells exposed to CJE. Conclusion: Exposure of A549 human NSCLC cells to CJE inhibits the proliferation, increases the cytotoxicity, and decreases the ability of cells to migrate and grow. Moreover, the expression of caspase-3 increases after CJE treatment, suggesting that the apoptosis of NSCLC cells is induced by a chain reaction initiated by caspase-3. These results indicate that Citrus junos is a potential therapeutic agent for human non-small-cell lung cancer.

  • Background: The human lung serves as a niche for a unique and dynamic bacterial community related to the development and aggravation of multiple respiratory diseases. Therefore, identifying the microbiome status is crucial to maintaining the microecological balance and maximizing the therapeutic effect on lung diseases. Therefore, we investigated the histological type-based differences in the lung microbiomes of patients with lung cancer. Methods: We performed 16S rRNA sequencing to evaluate the respiratory tract microbiome present in bronchoalveolar lavage fluid. Patients with non-small cell lung cancer were stratified based on two main subtypes of lung cancer: adenocarcinoma and squamous cell carcinoma (SqCC). Results: Among the 84 patients analyzed, 64 (76.2%) had adenocarcinoma, and 20 (23.8%) had SqCC. The α- and β-diversities showed significant differences between the two groups (p=0.004 for Chao1, p=0.001 for Simpson index, and p=0.011 for PERMANOVA). Actinomyces graevenitzii was dominant in the SqCC group (linear discriminant analysis [LDA] score, 2.46); the populations of Haemophilus parainfluenza (LDA score, 4.08), Neisseria subflava (LDA score, 4.07), Porphyromonas endodontalis (LDA score, 3.88), and Fusobacterium nucleatum (LDA score, 3.72) were significantly higher in the adenocarcinoma group. Conclusion: Microbiome diversity is crucial for maintaining homeostasis in the lung environment, and dysbiosis may be related to the development and prognosis of lung cancer. The mortality rate was high, and the microbiome was not diverse in SqCC. Further large-scale studies are required to investigate the role of the microbiome in the development of different lung cancer types.

  • The diffuse nodular lung lesion has a diagnostic problem and should be made differential diagnosis. A chest X-ray of 62-year-old male patient with dyspnea showed small-sized scattered multinodular lesion on entire lung field. Bronchoalveolar lavage and transbronchial needle aspiration showed the non-specific findings, so open lung biopsy was done and revealed bronchioloalveolar cell carcinoma.
