Objectives: To study variation in T lymphocyte subgoups and its clinical significance in non-small cell lung cancer (NSCLC). Methods: Levels of CD3+, CD4+, CD8+, CD4+/CD8+, NK and Treg cells in peripheral blood of NSCLC cases and healthy adults were determined by flow cytometry. Results: CD3+, CD4+ and CD4+/CD8+ ratio and NK cells in NSCLCs were decreased significantly in comparison with the control group (P < 0.01), and decreased with increase in the clinical stage of NSCLC, while CD8+ cells demonstrated no significant change (P > 0.05). Treg cells were significantly more frequent than in the control group (P < 0.01), and increased with the clinical stage of NSCLC. Conclusion: The cellular immune function of the NSCLC patients is lowered. It is important to detect change of T lymphocyte subgroups by flow cytometry for the diagnosis, treatment and prognostic assessment of NSCLC patients.

The objective of this retrospective study was to investigate prognostic factors associated with survival of patients with extensive stage small cell lung cancer (ES-SCLC). Included were 200 patients admitted to the Liberation Army General Hospital with a diagnosis of ES-SCLC. The demographics of patients, disease characteristics, pre-treatment biochemical parameters and therapeutic plan were assessed or evaluated. Univariate analysis found that second-line chemotherapy, radiotherapy, and no liver metastasis were associated with improved survival. Tumor response to first-line chemotherapy and normal initial hemoglobin levels were also associated with a survival benefit (all P-values ${\leq}$ 0.0369). Multivariate Cox regression analysis indicated that liver metastasis and the total number of all chemotherapy cycles were independent prognostic factors of survival. The morbidity risk in patients with liver metastasis was 2.52-fold higher than that in patients without liver metastasis (hazard ratio (HR)=2.52 (1.69-3.76); P<0.0001). However, one unit increase in the total number of chemotherapy cycles decreased the risk of death by 0.86-fold (HR=0.86 (0.80-0.92); P<0.0001). Absence of liver metastasis and ability of a patient to receive and tolerate multiple lines of chemotherapy were associated with longer survival.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. Standard treatment such as chemotherapy, radiotherapy, and surgery have many limitations in the treatment of this disease. Therefore, new molecular-targeted therapies needed and being developed. Patients with advanced NSCLC have a short life expentancy; therefore, in addition to increasing their survival, improving their quality of life (QoL) is also an important treatment goal. In this case report, we introduce NSCLC patient treated with Allergen Removed Rhus Verniciflua Stokes(aRVS). In this case, survival time incresed as traditional korean medicine using aRVS. And the general condition of the patient became better. Further case study will be needed in order to determine the effects of aRVS on NSCLC.

Background: Lung cancer is one of the commonest and most lethal cancers throughout the world. The majority of the patients present at advance stage and are not suitable for curative intent treatment. Even among patients with localized disease, there has been underutilization of curative treatment modalities. The aim of this study was to analyze the radical treatment utilization rates in patients with non small cell lung cancer (NSCLC) treated at our centre. Materials and Methods: We analyzed case records of 104 patients with a pathologically confirmed diagnosis of NSCLC having stage 1-3B disease who were treated at our centre over last 3 years, to assess the utilization of curative treatment modalities i.e. surgery or radical radiotherapy. Results: The median age of this cohort was 58 years. Out of 104 patients only 33 (31.7%) received curative intent treatment, 14 undergoing curative resection and 19 receiving radical doses of radiotherapy. The baseline characteristics of both the groups (with or without radical treatment) were not different. Major factors associated with underutilization with curative treatment were progressive disease or loss of follow up after chemotherapy and inappropriate use of TKI and/or palliative radiotherapy in patients with stage 1-3B disease. Patients who did not receive radical treatment had inferior PFS and OS than those who received radical treatment. Conclusions: In our practice we observed gross underutilization of curative intent treatment modalities in patients with NSCLCs which is associated with inferior survival.

Lung cancer is the most common primary tumor of brain metastasis. Metastasis to the brain is a frequent complication of non-small cell lung cancer (NSCLC) occuring in 12 ~ 18% of patient. The incidence of brain metastasis is rising because of longer survival of cancer patients as a result of the increase in early diagnosis of primary tumors and aggressive management, and improvements in imaging quality and accessibility such as widespread use of MRI. The most common symptoms are gradual onset of headache, focal weakness, and mental changes. Surgery, chemotherapy, radiotherapy and steroid therapy are treatment of NSCLC with brain metastasis. We report a patient with NSCLC metastasis to the brain. This patient underwent chemotherapy, radiotherapy and steroidtherapy. However, the patient requested oriental medical treatment for the patient's continuous headache and disease. We administered Banhabaekchulchoenma-tang gagambang with Allergen-removed Rhus Verniciflua Stokes(aRVS). The patient showed remarkable improvement in terms of frequency and severity of headache. Further study will be needed in order to determine the long-term effectiveness of oriental medical treatment on cancer patient with headache.

Gefitinib은 진행성 비소세포성 폐암에 사용이 증가되고 있는 새로운 표적 항암 치료제로써 대부분이 경미한 부작용을 보이나 심각한 약제 유발성 간질성 폐렴이 발생 할 수 있다. 발생 빈도가 높은 일본에서는 유병률이 3.5%까지도 보고 된 바 있으나 현재 우리나라에서는 EAP에서 확인된 1건을 제외하고는 보고가 거의 없어 gefitinib로 인한 간질성 폐렴에 대한 낮은 인지도와 감별 진단의 어려움 등이 문제가 되는 것으로 판단된다. 저자들은 gefitinib에 의한 간질성 폐렴 2례를 경험하였기에 이를 보고하는 바이다.

Background: Lung cancer is the most common cause of cancer-related death worldwide. The incidence of lung cancer is aproximately 7-8 thousand percent in Turkish women. In this study, we aimed to evaluate the clinical, pathological properties and survival data of female patients with lung cancer who were treated in our center. Materials and Methods: From 2007 to 2012, 50 women with lung cancer were enrolled. Patient data were evaluated retrospectively. Results: The median age was 61 (40-81). Forty patients (80%) were diagnosed with non small cell lung cancer (NSCLC), 10 patients (20%) were small cell carcinoma (SCC). Twelve (24%) patients were smokers and 13 of 16 non-smokers had a history of exposure to asbestos. The most common histologic subtype was adenocarcinoma (46%) and this accounted for 71% in patients with exposure to asbestos. The most common initial Eastern Cooperative Oncology Group (ECOG) performance score was 1 (24 patients, 48%) and initial stage was IV (25 patients, 50%) in the study group. During the median 15 months (1-96 months) followup period: 1 year overall survival (OS) was 68%, 2year overall survival was 36% and the median survival time was 19 months. According to univariate analysis, poor ECOG performance status, advanced stage, anemia and weight loss at time of diagnosis were negative prognostic factors. However, adenocarcinoma sub-type was a positive prognostic factor. Conclusions: In this study NSCLC sub-type, poor ECOG performance score, advanced stage, anemia and weight loss were prognostic factors in Turkish women with lung cancer.

A total of 134 patients with stage 1 of non-small cell lung cancer treated by carbon ion beam of HIMAC NIRS were investigated for control rate and delivered dose. The delivered dose of every patient was converted to biological effective dose (BED) of LQ model using fraction number, dose per fraction and alpha beta ratio which shows the maximum correlation between BED and tumor control. The BED of every patient was classified to establish a BED response curve for control. Assuming fraction numbers, dose response curves were introduced from BED response curve. The total doses to realize several control rates were obtained for the treatment of small fraction number.

Purpose: Currently lung cancer ranks second in cancer for incidence rate and is a disease that ranks first for a death rate by cancerous growth because it is already advanced at the time of diagnosis. The purpose of this paper was to analyze the factors that affect the effectiveness of and rash occurrence by Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR TKI) in patients with non-small cell lung cancer. Methods: A retrospective chart review of 100 patients, who took EGFR TKI (erlotinib, gefitinib) among patients who were diagnosed with non-small cell lung cancer in a Hospital in Korea between May 2005 and February 2008, was conducted. The drug effectiveness was evaluated by Response Evaluation Criteria In Solid Tumor. Results: EGFR mutation was the only factor associated with drug response (complete response and partial response). When stable disease was added to drug response as the evaluation parameter, ECOG and rash as well as EGFR mutation were found to be important factors. Survival, however, was not affected by EGFR mutation. The factors influenced on survival were older age (${\geq}65$), low ECOG ($1{\sim}2$), adenocarcinoma and rash. In the case of rash, group with EGFR mutation or low ECOG showed significantly higher chance of occurrence. There was no significant difference in rash occurrence between gefitinib and erlotinib groups. Conclusions: Based on the results, EGFR mutation positive and low ECOG ($1{\sim}2$) were significantly important factors for both effectiveness of EGFR TKI and rash occurrence. Also, rash itself was found to be an independently significant factor for the disease control and survival. Therefore, while administering EGFR TKI, patients who have the factors associated with rash occurrence should be closely monitored for effective and safe drug therapy.
