Objective: The purpose of this study is to report the case of a patient with non-small cell lung adenocarcinoma (NSCLC) with anaplastic lymphoma kinase (ALK) mutation treated by Samchilchoongcho-Jung in conjunction with Crizotinib. Methods: An NSCLC patient diagnosed with multiple pleural and lymph nodes metastasis has been taking Crizotinib (500 mg/day) since January 2014. The patient has been treated with Samchilchoongcho-Jung (1,500 mg/day) since June 2014. The tumor size was measured by computed tomography (CT) and laboratory analysis was conducted. Adverse events were evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0. Results: After combining treatment, stable disease was shown on CT. The tumor marker (CEA, Cyfra 21-1) levels were maintained. NCI-CTCAE 5.0 showed no adverse events. Conclusion: This case study suggests that Samchilchoongcho-Jung may contribute to tumor response, in conjunction with Crizotinib on the treatment of patients with NSCLC.

We have experienced 120 non-small cell primary carcinomas of the lung between June, 1974 and December, 1984, at Seoul National University Hospital. They were 107 males and 13 females. 95% of all were ranged from 40 years to 69 years of age with 56 years of mean age. They were composed of 70 [66.7%] squamous cell ca., 20 [19%] adenoca., 6 [5.7%] undifferentiated large cell ca., 4 [3.8%] undifferentiated small cell ca., and 5 [4.8%] mixed adenosquamous cell ca. 41 [36%] and 35 [30.7%] patients have received pneumonectomies and lobectomies with a 66.7% resectability rate. Of the 36 stage I and 21 stage II patients, 56 were resectable but only 20 [31.7%] of the 63 stage III patients were resectable. This informed us the significance of the stage of the disease at the time of operation. The actuarial survival rate in 70 patients was as follow: 1, 3, 5 year survival rate of the patients in stage I were 80%, 80%, and 60% respectively. Both 1, 3 year survival rate of patients in stage II were 84%. But 1, 2, 3 year survival rate of patients in stage III were 40%, 11%, and 5% respectively. By dividing the patients in stage III into resectable group and nonresectable one, both 1, 2 year survival rate of the former were 37% and those of the latter were 42% and 7%. According to the cell type of the cancer, 1, 3, 5 year survival rate of the squamous cell ca. were 63%, 40%, and 26% respectively. 1, 3 year survival rate of the adenoca. were 43% and 34%. Hospital death were only 2 cases with a 1.7% operative mortality rate. We had acceptable long-term survival rate and have convinced the necessity and hope of the early detection and resection of the lung carcinoma.

BACKGROUND/OBJECTIVES: Perilla frutescens Britton leaves are a commonly consumed vegetable in different Asian countries including Korea. Cancer is a major cause of human death worldwide. The aim of the current study was to investigate the inhibitory effects of ethanol extract of perilla leaf (PLE) against important characteristics of cancer cells, including unrestricted growth, resisted apoptosis, and activated metastasis, using human cancer cells. MATERIALS/METHODS: Two human cancer cell lines were used in this study, HCT116 colorectal carcinoma cells and H1299 non-small cell lung carcinoma cells. Assays using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide were performed for measurement of cell growth. Soft agar and wound healing assays were performed to determine colony formation and cell migration, respectively. Nuclear staining and cell cycle analysis were performed for assessment of apoptosis. Fibronectin-coated plates were used to determine cell adhesion. RESULTS: Treatment of HCT116 and H1299 cells with PLE resulted in dose-dependent inhibition of growth by 52-92% (at the concentrations of 87.5, 175, and $350{\mu}g/ml$) and completely abolished the colony formation in soft agar (at the concentration of $350{\mu}g/ml$). Treatment with PLE at the $350{\mu}g/ml$ concentration resulted in change of the nucleus morphology and significantly increased sub-G1 cell population in both cells, indicating its apoptosis-inducing activity. PLE at the concentration range of 87.5 to $350{\mu}g/ml$ was also effective in inhibiting the migration of H1299 cells (by 52-58%) and adhesion of both HCT116 and H1299 cells (by 25-46%). CONCLUSIONS: These results indicate that PLE exerts anti-cancer activities against colon and lung cancers in vitro. Further studies are needed in order to determine whether similar effects are reproduced in vivo.

Background and Objective: Lung cancer is one of the malignant diseases which most seriously threat humansurvival and development. This study aimed to assess osteopontin (OPN) expression in non-small cell lung cancer (NSCLC) and any relationship with clinicopathological features. Methods: Immunohistochemistry was used to determine OPN expression and microvascular density (MVD) in 120 cases of NSCLC also undergoing clinical assessment. Results: Moderately positive expression of OPN was found in 34.6% (41/120) and strong expression in 47.5% (57/120) of the NSCLCs; OPN expression in carcinomas was higher than in pericarcinoma tissues (P<0.05). While no obvious association was observed with NSCLC patient age, gender, maximum diameter of the tumor and pathological type, OPN expression was more commonly detected in poorly differentiated carcinoma tissue and lymph node metastasis as well as at advanced clinical stage (P<0.05); OPN expression in cancer tissue was positively correlated with MVD (r = 0.839, P = 0.000). Conclusion: OPN plays an important role in promoting tumor angiogenesis and progress of NSCLCs and has the possibility to become the new target for therapy.

Purpose: Stereotactic radiosurgery (SRS) has been introduced for small-sized single and oligo-metastases in the brain. The aim of this study is to assess treatment outcome, efficacy, and prognostic variables associated with survival and intracranial recurrence. Materials and Methods: This study retrospectively reviewed 123 targets in 64 patients with non-small cell lung cancer (NSCLC) treated with SRS between January 2006 and December 2012. Treatment responses were evaluated using magnetic resonance imaging. Overall survival (OS) and intracranial progression-free survival (IPFS) were determined. Results: The median follow-up was 13.9 months. The median OS and IPFS were 14.1 and 8.9 months, respectively. Fifty-seven patients died during the follow-up period. The 5-year local control rate was achieved in 85% of 108 evaluated targets. The 1- and 2-year OS rates were 55% and 28%, respectively. On univariate analysis, primary disease control (p < 0.001), the Eastern Cooperative Oncology Group (ECOG) performance status (0-1 vs. 2; p = 0.002), recursive partitioning analysis class (1 vs. 2; p = 0.001), and age (<65 vs. ${\geq}65$ years; p = 0.036) were significant predictive factors for OS. Primary disease control (p = 0.041) and ECOG status (p = 0.017) were the significant prognostic factors for IPFS. Four patients experienced radiation necrosis. Conclusion: SRS is a safe and effective local treatment for brain metastases in patients with NSCLC. Uncontrolled primary lung disease and ECOG status were significant predictors of OS and intracranial failure. SRS might be a tailored treatment option along with careful follow-up of the intracranial and primary lung disease status.

$O^6-methylguanine-DNA$ methyltransferase (MGMT) is a DNA repair protein that protects cells against the carcinogenic effects of alkylating agents. The loss of MGMT expression was commonly known due to hypermethylation of CpG islands in its promoter region. We evaluated the expression of MGMT by immunohistochemistry in order to examine the relationship between loss of MGMT expression and clinicopathological characteristics in 74 Korean patients with non-small cell lung cancers. Loss of MGMT was detected in 25 (33.8%) of 74 cases. The loss of MGMT expression was frequently seen in the adenocarcinoma than in the squamous cell carcinoma (p=0.021). However, there was no significant differences between loss of MGMT expression and other clinicopathological characteristics, including age, gender, smoking status, tumor size, tumor T stage, and lymph node metastasis (p>0.05). In conclusion, loss of MGMT expression was related with the histologic type of lung cancer. Further methylation study of MGMT promoter is needed to evaluate the relationships with immunohistochemical expression of MGMT and to clarify the role of MGMT in lung cancer.

Background: Acyl protein thioesterase-1 (APT1) is a cytosolic protein that may function in the depalmitoylation of numerous proteins, including the Ras family. However, the clinical role of depalmitoyl thioesterase in human cancer is not known. We evaluated the APT1 expression in lung cancer tissue and its clinicopathological findings according APT1 expression pattern. Methods: APT1 expression was examined by immunohistochemistry in the tumor tissue from 79 patients, who had undergone curative surgical removal of the primary lesion; all patients had been diagnosed with stage I non-small cell lung cancer between 1993 and 2004, at Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Korea. Results: The APT1 expression was seen in 50 out of 79 (63.3%) cases. The positive APT1 expression was significantly related with histologic subtype and T stage, but was not influenced by differentiation. The positive APT1 expression was not significantly related to patient age, gender, or smoking history. The median follow-up duration was 10.0 years; the 5-year survival rate was 71.0%. The positive APT1 expression group showed significantly worse overall survival and worse disease-free survival without statistical significance. Conclusion: We conclude that positive APT1 expression in stage I lung cancer after surgery is closely associated with overall survival. To evaluate APT1 as a prognostic marker in lung cancer, comprehensive studies on advanced stage cases are needed.

Background: This study focused on the association between preoperative serum carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (Cyfra 21-1) levels and pathologic parameters in patients with resected non-small-cell lung cancer (NSCLC). Materials and Methods: The records of 527 patients who underwent pulmonary resection of NSCLC were reviewed. The association between preoperative serum CEA and Cyfra 21-1 levels and variables that had p-values of less than 0.05 in a t-test or one-way analyses of variance was analyzed by multiple linear regression. Results: The mean serum CEA and Cyfra 21-1 levels prior to surgery were $6.8{\pm}23.1$ mg/dL (range, 0.01 to 390.8 mg/dL) and $5.4{\pm}12.3$ mg/dL (range, 0.65 to 140.2 mg/dL). The serum CEA levels were associated with tumor (T) and lymph node (N) stage and histology. The serum Cyfra 21-1 levels were associated with T stage, tumor size, and histology. Multiple linear regression indicated that serum CEA levels were associated with T (T3/4 vs. T1: ${\beta}$=8.463, p=0.010) and N stage (N2/3 vs. N0: ${\beta}$=9.208, p<0.001) and histology (adenocarcinoma vs. squamous cell: ${\beta}$=6.838, p=0.001), and serum Cyfra 21-1 levels were associated with tumor size (${\beta}$=2.579, p<0.001) and histology (squamous cell vs. adenocarcinoma: ${\beta}$=4.420, p=0.020). Conclusion: Serum CEA level was correlated with T and N stage, and Cyfra 21-1 with tumor size. CEA and Cyfra 21-1 showed histologic correlation. CEA is mainly elevated in adenocarcinoma and Cyfra 21-1 in squamous cell carcinoma. These results might be helpful for predicting pathologic status in preoperative NSCLC.

Background: Despite advances in chemotherapy, the treatment of inoperable non-small cell carcinoma of the lung remains poor. According to the recent reports, the response rates of mitomycin, vinblastine, and cisplatin(MVP) chemotherapy are higher than those of other cisplatin based polychemotherapy and MVP chemotherapy can be used as neoadjuvant chemotherapeutic regimen. But the overall response rates of MVP chemotherapy range from 17 to 53 percent, so we studied the effect of MVP chemotherapy in advanced non-small cell lung cancer. Method: We treated forty patients with stage III or IV non-small cell lung cancer with two courses of MVP chemotherapy($8mg/m^2$ of mitomycin on day 1, $6mg/m^2$ of vinblastine on day 2 & day 14, and $100mg/m^2$ of cisplastin on day 1) at 4 weeks interval. Then all patients were evaluated the response of chemotherapy 4 weeks later, and received further chemotherapy, palliative radiotherapy or supportive therapy according to the patient's condition. We also determined the median survival time and prognostic factors. Results: 1) Nine patients(23%) had a partial reponse, 23 patients(57%) had a stable disease, and disease progressed in 8 patients(20%). There were no patients with complete response. 2) The overall median survival time was 36 weeks(range, 9 to 119+ weeks). The median survival time of responder(partial response) and non-responder(stable and progressed) groups were 60 weeks(range, 36 to 82+ weeks) and 31 weeks(range, 9 to 119+ weeks) respectively(p=0.03). 3) The median survival time of the female group was 71 weeks and significantly prolonged in comparision with 35 weeks of the male group(p=0.01). But, the other prognostic factors didn't affect the survival time and response rate. 4) The median survival times of chemotherapy group and chemotherapy with palliative radiotherapy group were not significantly different. Conclusion: MVP combined chemotherapy is unsatisfactory in improving survival in advanced non-small cell lung cancer. Therefore, further studies are needed to find more active new agents and to estabilish the efficacy of the combined treatment with radiotherapy and/or surgery.

Abraxane (nab-paclitaxel) is a member of the group of nano chemotherapeutics. It is approved for metastatic breast cancer and non small cell lung cancer. Trials for several cancer types including gynecological cancers, head and neck, and prostatic cancer are being studied. In this study, the antiproliferative and apoptotic effect of abraxane was evaluated on HeLa cell line originated from human cervix carcinoma. Three different doses ($D_1$=10 nM, $D_2$=50 nM, $D_3$=100 nM) were administered to HeLa cells for 24, 48 and 72 h. The 50 nM dose of abraxane decreased DNA synthesis from 4.62-0.08%, mitosis from 3.36-1.89% and increased apoptosis from 10.6-30% at 72 h. Additionally, tripolar metaphase plates were seen in mitosis preparations. In this study, abraxane effected cell kinetic parameters significantly. This results are consistent with other studies in the literature.
