With the introduction of X-rays of higher energy that have higher penetrability, it has become possible to treat the deep-seated tumor with increased local control rate. But at the same time it has incrased the damage to the deep seated organs, especially to the lung which is known to be the less radiotolerable tissue in the body. This study analyses the 66 patients who were exposed to the irradiation of the lung, and examines the development of radiation pneumonitis and its related factors. The results of the study are summarized as follows: 1, The 66 patients were consisted of 40 cases of lung cancer, 15 cases of breast cancer and 11 cases of mediastinal tumors. There were 37 males and 29 females with the male to female ratio 1.3: 1. A male to female ratio in the lung cancer was 3: 1. 2. Among 66 patients, 26 patients $(39\%)$ developed the radiographical changes of acute radiation pneumonitis and 13 out of 26 patients $(50\%)$ showed the clinical features of acute radiation pneumonitis. 3. The onest of acute radiation pneumonitis ranged from 10 days to 6 months after the completion of radiotherapy. 4. There was a statistically significant close relationship between the development of radiation pneumonitis and the radiation dose. 5. As the irradiated lung volume increased, the development of radiation pneumonitis increased. But the statistical significance was not strong. 6. The increased incidence of radiation pneumonitis was observed when the chemotherapy was given before or concomittantly with radiotherapy. 7 There was no significant correlation between the development of radiation pneumonitis and the age, smoking and the presence of underlying lung disease.

Background: Docetaxel is one of the standard treatments for advanced non-small cell lung cancer. Docetaxel is usually administered in a 3-week schedule, but there is significant toxicity. In this phase II clinical study, we investigated the efficacy and safety of a 4-weekly schedule of docetaxel monotherapy, as first-line chemotherapy for advanced squamous cell carcinoma in elderly lung cancer patients. Methods: Patients with stage IIIB/ IV lung squamous-cell carcinoma age 70 or older, that had not undergone cytotoxic chemotherapy were enrolled. Patients received docetaxel $25mg/m^2$ on days 1, 8, and 15, every 4 weeks. Primary endpoint was the objective response rate (ORR). Secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity profiles. Results: A total of 19 patients were enrolled. Among 19 patients, 17 were for evaluated efficacy and safety. In the intent-to-treat population, ORR and disease control rate (DCR) were 11.8% and 47.1%, respectively. In the response evaluable population, ORR was 16.7% and DCR was 66.7%. Median PFS and OS were 3.1 months and 3.3 months, respectively. There were three adverse grade 3/4 events. Grade 1 neutropenia was reported in one patient. Conclusion: Our data failed to demonstrate efficacy of a 4-weekly docetaxel regimen, in elderly patients with a poor performance status. However, incidence of side effects, including neutropenia, was lower than with a 3-week docetaxel regimen, as previously reported.

Background: No consensus exists regarding whether volatile anesthetics are superior to intravenous anesthetics for reducing postoperative pulmonary complications (PPCs) in patients undergoing general anesthesia for surgery. Studies of this issue focused on anatomic pulmonary resection are lacking. This study compared the effects of total intravenous anesthesia (TIVA) versus volatile anesthesia on PPCs after anatomic pulmonary resection in patients with lung cancer. Methods: This retrospective study examined the medical records of patients with lung cancer who underwent lung resection at our center between January 2018 and October 2020. The primary outcome was the incidence of PPCs, which included prolonged air leak, pneumonia, acute respiratory distress syndrome, empyema, atelectasis requiring bronchofiberscopy (BFS), acute lung injury (ALI), bronchopleural fistula (BPF), pulmonary embolism, and pulmonary edema. Propensity score matching (PSM) was used to balance the 2 groups. In total, 579 anatomic pulmonary resection cases were included in the final analysis. Results: The analysis showed no statistically significant difference between the volatile anesthesia and TIVA groups in terms of PPCs, except for prolonged air leak. Neither of the groups showed atelectasis requiring BFS, ALI, BPF, pulmonary embolism, or pulmonary edema after PSM. However, the length of hospitalization, intensive care unit stay, and duration of chest tube indwelling were shorter in the TIVA group. Conclusion: Volatile anesthetics showed no superiority compared to TIVA in terms of PPCs after anatomical pulmonary resection in patients with lung cancer. Considering the advantages of each anesthetic modality, appropriate anesthetic modalities should be used in patients with different risk factors and situations.

Background: It is well known that skin cancer and precancerous disease develop more frequently in patients undergoing solid organ transplantation than normal populations in the normal population in Western countries. However, to date, the clinical and demographic features of skin cancer and precancerous disease after solid organ transplantation are not established in Asian countries. We evaluated the clinical and demographic features of primary skin cancer and precancerous lesions after solid organ transplantation and compared these with the trends observed in Western countries. Methods: We retrospectively reviewed the medical records of patients who underwent kidney, liver, heart, and lung transplantation between January 1995 and April 2017 and who developed skin cancer or precancerous lesions after transplantation. The various lesions observed were squamous and basal cell carcinoma, malignant melanoma, Kaposi sarcoma, Bowen's disease, and actinic keratosis. Results: We identified 4604 patients who received organ transplant. The mean age of patients was 44.8 years (male, 64.6%; female, 35.4%), and the sum of the person-year of observation time was 31,024 person-years. The incidence rate per 100,000 person-years was 29.01 for squamous cell carcinoma, 19.34 for basal cell carcinoma, 6.45 for malignant melanoma 3.22 for Kaposi sarcoma, and 74.17 for Bowen's disease and actinic keratosis. The incidence rate per 100,000 person-years was the highest in patients undergoing heart transplantation (610.50), followed by those who underwent kidney transplantation (136.54) and liver transplantation (90.15). Koreans showed lower incidence rates than those observed in Westerners. Conclusion: The incidence of primary skin cancer and precancerous lesions after solid organ transplantation in Koreans was lower than that in Westerners. Squamous cell carcinoma was the most common skin cancer in patients undergoing solid organ transplantation and the incidence rate of skin cancer and precancerous lesions was the highest in patients undergoing heart transplantation.

A total of 178 patients with primary lung cancer who had undergone complete resection of the tumor in combination with complete mediastinal lymphadenectomy were reviewed at the Department of Thoracic and Cardiovascular Surgery of Yonsei Medical Center from January 1980 through July 1989. Materials; 1. There were 45 men and 33 women ranging of age from 25 to 78 years with a mean age of 55.4 years. 2. Histological types were squamous carcinoma in 115 cases [64.6%] adenocarcinoma in 42 cases [23.6 %], bronchioloalveolar carcinoma in 9 cases [5.1%], large cell carcinoma in 8 cases [4.5 %] and small cell carcinoma in 4 cases [2.2%] Results were summarized as follows: 1. The size of primary tumor was not directly proportional to the frequency of mediastinal lymph node metastasis. [P =0.0567] 2. The histologic types of the primary tumor did not related to the incidence of mediastinal lymph node metastasis. [P >0.19] 3. The chance of mediastinal lymph node metastasis in the case with lung cancer located in right middle lobe[31.8%, N=22] and left lower lobe [31.4%, N=32] were the highest and the lowest was the one located in right lower lobe, while over all incidence of mediastinal lymph node metastasis in this series was 25.4 % [N=55]. 4. The rate of mediastinal lymph node metastasis without evidence of regional and hilar lymph node metastasis was 13%. [N=23] The chance of mediastinal lymph node involvement without N1 lymph node metastasis was 16.3 % [N=17] in both upper lobes and 8.2 % [N=6] in both lower lobes. It was statistically significant that the tumors in the upper lobes had greater chance of the mediastinal lymph node metastasis without N1 than the tumors in the lower lobes. 5. In this series majority of the patients with lung cancer the mediastinal lymph node metastasis from the tumor in each pulmonary lobes usually occurs via ipsilateral tracheobronchial and paratracheal lymphatic pathway. Especially the lung cancer located in lower lobes can metastasize to subcarinal, paraesophageal and inferior pulmonary ligamental lymph node through the lymphatic pathway of inferior pulmonary ligament. It can be speculated that in some cases of this series otherwise mediastinal lymph node metastasis can also occur with direct invasion to the parietal pleura and to the mediastinal lymph node via direct subpleural lymphatic pathway .

Purpose: To investigate whether it is safe to use leucogen tablets 60 mg three times per day (180 mg for a day) and whether this regimen could reduce the incidence of febrile neutropenia caused by chemotherapy. Methods: This prospectively designed study focused on the safety and effectiveness of leucogen tablets 60mg three times per day for a group of cancer patients during chemotherapy for mainly lung or gastric cancers. The tablets were administered from 5 days before until the termination of chemotherapy. Neutropenia and other healthcare encounters were defined as events and occurrence was estimated for comparison. Results: We identified 39 patients receiving leucogen tablets 60mg three times per day, including 11 with gastric, 12 with lung and 16 with other sites of cancer. The mean age was 65 (29-75) years and there were 27 male and 12 female patients. The mean duration of leucogen tablets intake was 59 days. Eighteen patients were treated with taxane-based, 4 with irinotecan-based and 17 with other chemotherapy. The incidence of febrile neutropenia was 0%. Twelve patients were found severe neutropenia (grade III/IV), and the duration of severe neutropenia (grade III/IV) was 5 days. Treatment-emergent adverse events were attributable to complications of myelosuppressive chemotherapy or the primary disease (i.e., alopecia, nausea, asthenia, neutropenia, and severe hepatic renal dysfunction). No chemotherapy was delayed and no treatment related death was observed. Conclusions: This study suggested that leucogen tablets 60mg three times per day (180mg for a day) are safe and could be effective for preventing febrile neutropenia in patients with chemotherapy.

배경: 비소세포폐암에서 전폐절제술은 총 시행 술식 중 $20 {\~}35\%$를 차지하고 있으며 특히 우측 전폐 절제술의 경우 $10{\~}25\%$의 높은 사망률이 보고되고 있다. 이에 저자들은 전폐 절제술 후 일어날 수 있는 합병증의 양상을 알아보고 술식에 따른 합병증의 양상과 원인, 그리고 사망률에 미치는 원인을 알아보고자 하였다. 대상 및 방법: 1987년 8월부터 2002년 4월까지 원자력병원 흥부외과에서 비소세포폐암으로 전폐절제술을 시행 받은 환자들의 의무기록을 후향적으로 조사하였다. 결과: 총 386예의 전폐 절제술을 시행하였으며 좌측 238예, 우측 148예였으며 표준술식 207예, 확장술식 179예였다. 이중 115예의 합병증($28.5\%$)이 발생하였고, 12예에서 사망하여 $3.1\%$의 수술 사망률을 보였다. 이는 같은 기간에 시행된 폐엽 절제술의 수술사망률($2.1\%$)과 비슷하였다. 사망 예를 좌우로 구분해보면 좌측2예($0.5\%$), 우측 10예($2.6\%$)였다. 합병증을 증상별로 분류하면 애성 42예, 폐렴 및 급성호흡부전 17예(9예), 농흉 8예, 기관지-늑막루 5예(1예), 재수술을 요하는 출혈 5예(1예), 부정맥 5예, 폐 부종 1예(1예), 기타 25예이었다(괄호 안은 그 합병증에 의한 사망예). 수술사망에 영향을 미치는 요인으로는 먼저 확장 술식 6예($3.3\%$), 표준 술식 6예($2.9\%$)의 수술 사망을 보여 두 군간의 유의 있는 차이는 보이지 않았다(p=0.812). 그리고 60세 미만군(n=204)에서 2예($1.0\%$), 60세 이상 군(n=182)에서 10예($5.5\%$)가 사망하여 의미 있는 차이를 보였으며(p=0.016), 좌우를 비교했을 때 우측의 사망률이 5배정도 높았으며 통계적으로도 의미 있는 차이를 보였다(p=0.002). 호흡기계 합병증에 영향을 미치는 요인을 보면 60세 이상 군에서 20예($11.0\%$)와 60세 미만 군에서 7예($3.4\%$)로 60세 이상 군에서 의미 있는 차이를 보였으며(p=0.005), 좌측 전폐 절제술 군에서 10예($4.2\%$)와 우측 전폐 절제술 군에서 17예($11.5\%$)로 우측에서 의미 있는 차이를 보였다(p=0.008). 결론: 본 연구에서 전폐절제술의 수술사망과 호흡기계합병증은 60세 이상의 고령과 우측 전폐절제술 시 높아진다. 따라서 고 위험군의 수술 시에 수술대상환자의 선별과 수슬전 후 환자관리가 중요할 것으로 생각한다. 그러나 전폐절제술의 수술 사망률은 폐엽 절제술과 비슷하므로 폐암의 완전절제를 위해서는 전폐절제술은 안전하게 시행될 수 있는 술식으로 생각한다.

Background: Lung cancer has a high incidence worldwide, and most lung cancer-associated deaths are attributable to cancer metastasis. Although several medicinal properties of Panax ginseng Meyer have been reported, the effect of ginsenosides Rk1 and Rg5 on epithelial-mesenchymal transition (EMT) stimulated by transforming growth factor beta 1 (TGF-β1) and self-renewal in A549 cells is relatively unknown. Methods: We treated TGF-β1 or alternatively Rk1 and Rg5 in A549 cells. We used western blot analysis, real-time polymerase chain reaction (qPCR), wound healing assay, Matrigel invasion assay, and anoikis assays to determine the effect of Rk1 and Rg5 on TGF-mediated EMT in lung cancer cell. In addition, we performed tumorsphere formation assays and real-time PCR to evaluate the stem-like properties. Results: EMT is induced by TGF-β1 in A549 cells causing the development of cancer stem-like features. Expression of E-cadherin, an epithelial marker, decreased and an increase in vimentin expression was noted. Cell mobility, invasiveness, and anoikis resistance were enhanced with TGF-β1 treatment. In addition, the expression of stem cell markers, CD44, and CD133, was also increased. Treatment with Rk1 and Rg5 suppressed EMT by TGF-β1 and the development of stemness in a dose-dependent manner. Additionally, Rk1 and Rg5 markedly suppressed TGF-β1-induced metalloproteinase-2/9 (MMP2/9) activity, and activation of Smad2/3 and nuclear factor kappa B/extra-cellular signal regulated kinases (NF-kB/ERK) pathways in lung cancer cells. Conclusions: Rk1 and Rg5 regulate the EMT inducing TGF-β1 by suppressing the Smad and NF-κB/ERK pathways (non-Smad pathway).

This paper presents the most recent data on cancer rates and the burden of cancer in the ASEAN region. Epidemiological data were sourced from GLOBOCAN 2008 and disability adjusted life years (DALYs) lost were estimated using the standard methodology developed within the World Health Organization's Global Burden of Disease study. Overall, it was estimated there were over 700,000 new cases of cancer and 500,000 cancer deaths in ASEAN in the year 2008, leading to approximately 7.5 million DALYs lost in one year. The most commonly diagnosed cancers were lung (98,143), breast (86,842) and liver cancers (74,777). The most common causes of cancer death were lung cancer (85,772), liver cancer (69,115) and colorectal cancer (44,280). The burden of cancer in terms of DALYs lost was highest in Laos, Viet Nam and Myanmar and lowest in Brunei, Singapore and the Philippines. Significant differences in the patterns of cancer from country to country were observed. Another key finding was the major impact played by population age distribution on cancer incidence and mortality. Cancer rates in ASEAN are expected to increase with ageing of populations and changes in lifestyles associated with economic development. Therefore, ASEAN member countries are strongly encouraged to put in place cancer-control health care policies, focussed on strengthening the health systems to cope with projected increases in cancer prevention, treatment and management needs.

Objective : This study aimed to investigate differential cancer incidence among Sasangin comparing to healthy subjects in the Republic of Korea. Methods : The medical records of 169 patients who had taken diagnosis of Sasang constitution from October 2004 to January 2007 at the East-West Cancer Center in Dunsan Oriental Hospital of Daejeon University were reviewed. Diagnosis was done by Questionnaire for Sasang Constitution ClassificationII (QSCCII). Results : Among the 169 patients, 37.9%, 22.5% and 39.6% belonged to Soyangin, Taeumin and Soeumin, respectively. This is significantly different from the distribution rate of Sasang in amonghealthy subjects (29.1%, 46.9% and 24.0% respectively to Soyangin, Taeumin and Soeumin). This pattern appeared in a similar way among individual cancer analysis: breast cancer (37.5%, 21.9%, 40.6%), colon cancer (41.7%, 20.8% 37.5%), and HCC (35.0%, 20.0%, 45.0%). Stomach cancer typically showed remarkable incidence in Soeumin as high as 50.0% and lung cancer showed in Soyangin as high 46.7%, but it didn't have statistical significance. The mean age of 50.9 years was higher than for healthy people (46.3). Conclusion : Sasang distribution of cancer patients is different from that of healthy subjects. Further study is needed on individual cancers.
