  • Malignant pleural mesothelioma (MPM), an aggressive malignant tumor of mesothelial origin associated with asbestos exposure, shows a limited response to conventional chemotherapy and radiotherapy. Therefore, the overall survival of MPM patients remains very poor. Progress in the development of therapeutic strategies for MPM has been limited. We recently reported that the calpain inhibitor, calpeptin exerted inhibitory effects on pulmonary fibrosis by inhibiting the proliferation of lung fibroblasts. In the present study, we examined the preventive effects of calpeptin on the cell growth of MPM, the origin of which is mesenchymal cells, similar to lung fibroblasts. Calpeptin inhibited the proliferation of MPM cells, but not mesothelial cells. It also prevented 1) the expression of angiopoietin (Ang)-1 and Tie-2 mRNA in MPM cells, but not mesothelial cells and 2) the Ang-1-induced proliferation of MPM cells through an NF-kB dependent pathway, which may be the mechanism underlying the preventive effects of calpeptin on the growth of MPM cells. These results suggest potential clinical use of calpeptin for the treatment of MPM.

  • A retrospective study of 53 patients suffering from non-small cell carcinoma of lung with brain metastases is presented. They were treated in the Department of Therapeutic Radiology of Kyung Hee University Hospital from 1983 to 1990. There were 37 male and 10 female patients. The age range was 39 to 85 years (median=59). The most common histologic cell type of tumor was adenocarcinoma ($50.9\%$), followed by squamous cell carcinoma and large cell carcinoma. All patients were treated with whole-brain photon irradiation (WBI) using lateral opposing fields. The overall median survival time was 5 months. Age, sex, histologic type, and initial performance status were not prognostically important. The most important prognostic factors were the response to radiotherapy and the presence of brain metastases alone. increasing the dose of radiotherapy to the main bulk of tumor may improve the symptom-free survival or overall survival in patients who present with brain metastases as the sole site of extrathoracic disease.

  • Central diabetes insipidus (DI) is a disease caused by insufficient release of antidiuretic hormone. Central DI with lung cancer is very rare. Most of them are caused by the pituitary metastasis, and rarely, by the paraneoplastic syndromes. Central DI is diagnosed by the water deprivation test. The treatment consists of surgical resection, radiotherapy and administration of desmopressin. We report an unusual case of central DI with non-small cell lung cancer. The diagnosis was confirmed by water deprivation test. After the administration of desmopressin, the urine osmolarity was increased. The patient's symptoms and urine osmolarity were improved by intranasal desmopressin.

  • Background: Lung cancer is the most common cancer in males worldwide. The principal mode of treatment in the early stage of non-small cell lung cancer (NSCLC) is surgery. However, five-year survival is only about 15% for all stages. The aim is to investigate the effect of daily low dose cisplatin concurrently with radiation therapy in advanced NSCLC patients with poor performance status. Materials and Methods: Ten patients diagnosed as inoperable Stage IIIB NSCLC with comorbid disease were assessed retrospectively in Bezmialem Vakif University, Faculty of Medicine, Department of Radiation Oncology, between 2011 to 2013. ECOG performance status was between 3 and 4. Cisplatin was administered at $6mg/m^2$ daily, for 5 days a week concurrently with radiotherapy using 160-200 cGy daily fractions, 54 Gy being the lowest and 63 Gy being the highest dose. Results: Complete response at the primary tumour site was obtained in 20% patients. Grade I esophagitis was seen 70 percent of patients, and the grade II haematological toxicity rate was 20 %. Median survival time was 7 months. Conclusions: Median survival time was reasonable, despite the patients ECOG performance status of 3-4, which is similar to groups even without comorbid disorders in comparison to other published papers in the literature. Acceptable toxicity, high response rates and quality of life of patients are the other favourable features.

  • Postoperative radiotherapy of breast cancer makes it possible to reduce loco-regional recurrence of breast cancer. The treatment technique, which can reduce the low-dose region at the junction and lung, is required. To produce proper dose distribution of internal mammary chain and chest wall, authors tried to find the method to expose $^{60}Co\;\gamma-ray$ on internal mammary region and 7MeV electron on chest wall. Exposure time of $^{60}Co\;\gamma$ and monitor unit of 9MeV were selected so that dose of $^{60}Co$ at 4cm depth was the same as that of 7Mev electron at $80\%$ dose depth. The position and direction of electron beam were changed for $^{60}Co$ beam: $0^{\circ},\;5^{\circ}$ for 0cm seperation; $0^{\circ},\;5^{\circ},\;10^{\circ}$ for 0.5cm seperation; $5^{\circ},\;10^{\circ},\;15^{\circ}$ for 1cm seperation. The results are as followings. 1. When the seperation of two fields was increased, dose on the axis of $^{60}Co$ beam was increased and dose at the junction region decreased while the volume of lung to be exposed to high dose and hot spot size were irregularly changed. 2. The dose distribution in the target volume of internal mammary and chest wall was most ideal when the seperation of two fields was $0\~0.5cm$ and the direction of electron beam was parallel to $^{60}Co$ beam.

  • Purpose: This study was conducted to observe the outcomes of postoperative radiotherapy (PORT) with or without concurrent chemotherapy in resected non-small cell lung cancer (NSCLC) in single institution. Materials and Methods: From 2002 to 2013, 78 patients diagnosed with NSCLC after curative resection were treated with radiotherapy alone (RT, n = 48) or concurrent chemoradiation (CCRT, n = 30). The indications of adjuvant radiation therapy were N2 node positive (n = 31), close or involved resection margin (n = 28), or gross residual disease due to incomplete resection (n = 19). The median radiation dose was 57.6 Gy (range, 29.9 to 66 Gy). Results: Median survival time was 33.7 months (range, 4.4 to 140.3 months). The 5-year overall survival (OS) rate was 49.5% (RT 46% vs. CCRT 55.2%; p = 0.731). The 3-year disease-free survival rate was 45.5% (RT 39.4% vs. CCRT 55.3%; p = 0.130). The 3-year local control rate was 68.1% (RT 64.4% vs. CCRT 77.7%; p = 0.165). The 3-year DMFS rate was 56.1% (RT 52.6% vs. CCRT 61.7%; p = 0.314). In multivariate analysis, age ${\geq}66$ years and pathologic stage III were significant poor prognostic factors for OS. Treatment failure occurred in 40 patients. Four patients had radiologically confirmed grade 3 radiation pneumonitis. Conclusion: In NSCLC, adjuvant RT or CCRT after curative surgery is a safe and feasible modality of treatment. OS gain was seen in patients less than 66 years. Postoperative CCRT showed a propensity of achieving better local control and improved disease-free survival compared to RT alone according to our data.

  • Background: Associations between elevated C-reactive protein (CRP) and cancer risk have been reported for many years, but the results from prospective cohort studies remains controversial. A meta-analysis of prospective cohort studies was therefore conducted to address this issue. Methods: Eligible studies were identified by searching the PubMed and EMBASE up to October 2012. Pooled hazard ratios (HR) was calculated by using random effects model. Results: Eleven prospective cohort studies involving a total of 194,796 participants and 11,459 cancer cases were included in this meta-analysis. The pooled HR per natural log unit change in CRP was 1.105 (95% confidence interval (CI): 1.033-1.178) for all-cancer, 1.308 (95% CI: 1.097-1.519) for lung cancer, 1.040 (95% CI: 0.910-1.170) for breast cancer, 1.063 (95% CI: 0.965-1.161) for prostate cancer, and 1.055 (95% CI: 0.925-1.184) for colorectal cancer. Dose-response analysis showed that the exponentiated linear trend for a change of one natural log unit in CRP was 1.012 (95% CI: 1.006-1.018) for all-cancer. No evidence of publication bias was observed. Conclusions: The results of this meta-analysis showed that the elevated levels of CRP are associated with an increased risk of all-cancer, lung cancer, and possibly breast, prostate and colorectal cancer. The result supports a role of chronic inflammation in carcinogenesis. Further research effort should be performed to identify whether CRP, as a marker of inflammation, has a direct role in carcinogenesis.

  • A retrospective analysis was performed or 102 patients with non-small cell lung cancer who received the curative radiotherapy from August 1985 to October 1988 at the Department of Therapeutic Radiology of Chonnam University Hospital. The follow-up period was ranged from 1 to 37 months and the median follow-up time was 15 months. The acturial 1 and 2 year survival rate of all the patients was $28\%\;and\;5\%$, respectively. The median survival was 10 months for stage II, 6 months for stage IIIA, and 9 for IIIB and the actuarial 2 year survival tate was $12.5\%,\;12.1\%,\;and\;0\%$ respectively. The treatment failure was identified in 32 patients and the locoregional failure was seen in 9 patients ($28\%$) and the distant failure in 23 patients ($72\%$). The initial performance status was related to the survival with statistical significance (p<0.01), but the survival difference by the radiation dose was not statistically significant (p>0.05).

  • From Nov. 1983 through Jan. 1986, 43 patients with nonsmall cell lung cancer were treated by radiation therapy at Inje Medical College Paik Hospital. 38 patients were available for the analysis of this study. 33 patients received definite irradiation with curative intent, while 5 patients received postoperative irradiation. Chemotherapy was added in 12 patients before, during and after radio-therapy. 28 patients were squamous cell carcinoma and 10 patients were adenocarcinoma. There were 29 men and 9 women (median age, 50 years; range 34 to 74 years). Stage 1 was 1 patient, Stage 11,7 patient, and Stage 111,30 patients. Among 33 patients who received radiotherapy with curative intent, follow up radiological study revealed complete response in 12 patients $(36\%)$, partial response, in 9 patients $(27\%)$, and minimal response, in 5 patients $(15\%)$, while 7 patients $(21\%)$ were nonresponders. Median survival for all patients was 6.9 months; squamous cell carcinoma, 7.3 months, adenocarcinoma, 5.9 months. Responders survived median 7 months, while nonresponders survived median 1.9 months. Improved complete response rate and survival were shown in high radiation dose group. As prognostic factors, age, initial performance status, sex, histology and tumor location were evaluated.

  • Lung cancer is classified into squamous cell carcinoma, adenocarcinoma. large-cell carcinoma and small-cell carcinoma by histology. Squamous cell carcinoma which is frequently reported in Korea is not effected by anti-cancer chemotherapy but effected by surgery or radiotherapy. We experienced a 70 year-old male patient who had been discharged after having been diagnosed squamous cell carcinoma(stage III) and considered of a viable period of 3 month. However 2 years' taking boiled water of paecilomyces japonica and phellinus linteus, he showed normal chest X-ray and more healthy life. So it is suggested that paecilomyces japonica and phellinus linteus should be effect on squamous cell carcinoma of lung.
