Hypertrophic osteoarthropathy(HOA) is a systemic disorder characterized by proliferative periostitis of long bone and polysynovitis. Clubbing of the fingers and toes usually accompanies HOA. This syndrome is most frequently with lung cancer. Although disappearance of HOA with removal of the tumor is well known, very few typical cases are reported in Korea We report case of lung cancer with HOA, which was dramatically relieved after the surgical resection of the tumor.

Objectives: The purpose of this study is to report the effect of combination treatment of Traditional Korean medicine (TKM) and chemotherapy on a ovarian cancer with lung metastasis patient. Methods: One ovarian cancer with lung metastasis patient was treated by TKM in conjunction with Carboplatin/paclitaxel since Feb. 2020. Repeat cycle every 3 weeks for 6 times. The patient has been treated with TKM at the same time. To evaluate the patient, symptoms were measured by Numeric Rating Scale (NRS), Eastern Cooperative Oncology Group (ECOG) and tumor size was measured by scanning with Computed Tomography (CT). Blood tests including cancer biomarker were conducted during treatment. Adverse events were evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), version 5.0. Results: After treatment with Carboplatin/paclitaxel and TKM during 2 months, the size of the ovarian cancer was decreased(Partial Response, PR), size and malignant pleural effusion at right lung disappeared. And no evidence of newly developed metastatic lesions. After 2 months, the tumor response was stable disease while improving the performance and other symptoms. Conclusions: This case provides us conjunctive treatment with Conventional and Eastern medicine may have substantial benefit for patients with end-stage ovarian cancer.

Objective: This long-term case report details a case of pancreatic cancer with lung metastasis suppressed by integrative cancer medicine (IMT). Methods: A 64-year-old woman diagnosed with pancreatic cancer visited a Korean medicine hospital complaining about the side effects of chemotherapy for lung metastasis. She received IMT involving Korean traditional medicine and Western immunotherapy from May 2017 to June 2023. Tumor dimensions were assessed through computed tomography (CT) and positron-emission tomography/CT scans, while tumor markers and safety were monitored by laboratory tests. Results: IMT suppressed the progression of cancer, as observed by imaging and laboratory tests. The patient achieved 5-year survival, even after discontinuing chemotherapy. Conclusion: This case presents a potential therapeutic alternative for patients who are ineligible for chemotherapy or surgical interventions.

Background: About 30% to 40% of the patients with pathologic stage I non-small cell lung cancer (NSCLC) die within 5 years after complete resection. The identification of poor prognostic factors and the application of additional treatment are very important to improve the survival rate in resected stage I NSCLC. Materials and methods: Sixty-eight(68) patients who had been diagnosed postoperatively between Janury 1989 and December 1995 as having stage I non-small cell lung cancer according to the TNM classification were studied. The postoperative 5-year survival rate was calculated with the Kaplan-Meier method, and clinico- histopathologic factors including age, sex, operative method, type of tumor cell, T factor, grade of the differentiation in a squamous cell carcinoma, invasion of blood vessel and expression of the nm23-H1 protein were investigated and analyzed. Results: The median survival of the entire group of patients was 58$\pm$3 months, with a 5-year survival of 58.9%. In univariate analysis, invasion of blood vessel and poor differentiation of the tumor cell in a squamous cell carcinoma significantly worsened the survival. In multivariate analysis, invasion of blood vessel and grade of the differentiation of the tumor cells in a squamous cell carcinoma remained independent prognostic factors. High expression of the nm23-H1 protein was related to a high postoperative 5-year survival in comparision with low expression of the nm23-H1 pretein (73.0% vs 50.7%), but there was no statistical significance. Conclusions: These results highlight the negative prognostic value of poor differentiation of tumor cells in a squamous cell carcinoma and invasion of blood vessel in stage I non-small cell lung cancer. Also, further studies are necessary to be determined prognostic value of the T factor and expression of the nm23 protein in non-small cell lung cancer.

The effects of erlotinib combined with celecoxib in a lung cancer xenograft model were here explored with a focus on possible mechanisms. A xenotransplanted lung cancer model was established in nude mice using the human lung cancer cell A549 cell line and animals demonstrating tumour growth were randomly divided into four groups: control, erlotinib, celecoxib and combined (erotinib and celecoxib). The tumor major axis and short diameter were measured twice a week and after 40 days tissues were collected for immunohistochemical analyses of Bcl-2 and Bax positive cells and Western-blotting analyses for the epidermal growth factor recepto (EGFR), P-EGFR, and cyclooxygenase-2 (COX-2). Tumor size in the combined group was smaller than in the others (p<0.01) and the percentage of Bcl-2 positive cells was fewer in most cases (p<0.01), while that of Bax positive cells was greater than in the erlotinib and celecoxib groups (P>0.05). Western blotting showed decreased expression of P-EGFR and COX-2 with both erlotinib and celecoxib treatments, but most pronouncedly in the combined group (P<0.05). Simultaneous blockage of the EGFR and COX-2 signal pathways exerted stronger growth effects in our human xenotransplanted lung cancer model than inhibition of either pathway alone. The anti-tumor effects were accompanied by synergetic inhibition of tumor cell apoptosis, activation of p-EGFR and expression of COX-2.

Background: Video-thoracoscopy is known to be an useful method to provide accurate pre-resectional staging in patients with lung cancer in addition to the conventional radiologic studies and mediastinoscopy, for the pleural cavity is inspected directly and biopsy specimens call be obtained. This study is undertaken to evaluate how video-thoracoscopy can be used in deciding pre-resectional stage Material and Method: Video-thoracoscopy was performed in patients with lung cancer who were scheduled for surgical resection based on the radiologic staging and mediastinoscopic biopsy. 37 patients were included in this study. Pre-thoracoscopically 18 cases were in TNM stage 1, 7 in stage 2, and 12 in stage 3. Result: In 15 of 37 cases, video-thoracoscopy could not be performed effectively due to heavy adhesions in the pleural cavity, diaphragmatic and chest wall invasion of tumor and bulky tumor mass es. Mediastinal lymph nodes were positive postresectionally in 6 of these 15 cases. In 22 cases, video-thoracoscopy was performed as usual. Positive mediastinal lymph nodes were identified in 2 cases and exploratory thoracotomy was prevented. Surgical resection were carried out in remaining 20 cases and 5 cases among them had positive mediastinal lymph nodes. Conclusion: We believe that it is difficult to perform pre-thoracotorny video-thoracoscopy for all lung cancer patients for there were many cases that thoracoscory could not be undertaken doe to heavy adhesions in the pleural cavity, tumor involvement of the chest wall and/or diaphragm and bulky tumor mass. However we think it is helpful in preventing unnecessary exploratory thoracotomy for some patients with lung cancer whom pre-thoracotomy video-thoracoscopy was carried out.

Background : The moot important prognostic factor in non-small cell lung cancer is the TNM stage. Even after complete resection in early non-small cell lung cancer, the five-year survival rate is still low. However, new prognostic factors, including molecular biologic factors, have recently been found to guide the treatment of patients with non-small cell lung cancer. We evaluated the prognostic value of the loss of blood-group antigen A in tumor tissue, which has been implicated as an important prognostic factor for overall survival and the timing of the disease progression. Methods : The loss of blood-group antigen A was assessed immunohistochemically in paraffin-embedded tumor samples from 26 patients with blood types A or AB, who had undergone curative surgery. Monoclonal antibody was used to detect the blood group antigen A expression. Results : Fifteen patients (58%) expressed antigen A in their tumor tissue, whereas 11 patients (42%) did not show antigen A. The median survival time of the blood A antigen positive group was 11 months, while the median survival time of the blood A antigen negative group was 18 months. The difference in survival between the two groups was not statistically significant. Conclusion : The loss of blood-group antigen A in tumor tissue was not found to be a significant prognostic factor in patients with non-small cell lung cancer. This study needs to be extended for further evaluation.

Background: Concurrent chemo-radiotherapy is the recommended standard treatment modality for patients with locally advanced lung cancer. The purpose of three-dimensional conformal radiotherapy (3DCRT) is to minimize normal tissue damage while a high dose can be delivered to the tumor. The most common dose limiting side effect of thoracic RT is radiation pneumonia (RP). In this study we evaluated the relationship between dose-volume histogram parameters and radiation pneumonitis. This study targeted prediction of the possible development of RP and evaluation of the relationship between dose-volume histogram (DVH) parameters and RP in patients undergoing 3DCRT. Materials and Methods: DVHs of 41 lung cancer patients treated with 3DCRT were evaluated with respect to the development of grade ${\geq}2$ RP by excluding gross tumor volume (GTV) and planned target volume (PTV) from total (TL) and ipsilateral (IPSI) lung volume. Results: Were admitted statistically significant for p<0.05. Conclusions: The cut-off values for V5, V13, V20, V30, V45 and the mean dose of TL-GTV; and V13, V20,V30 and the mean dose of TL-PTV were statistically significant for the development of Grade ${\geq}2$ RP. No statistically significant results related to the development of Grade ${\geq}2$ RP were observed for the ipsilateral lung and the evaluation of PTV volume. A controlled and careful evaluation of the dose-volume histograms is important to assess Grade ${\geq}2$ RP development of the lung cancer patients treated with concurrent chemo-radiotherapy. In the light of the obtained data it can be said that RP development may be avoided by the proper analysis of the dose volume histograms and the application of optimal treatment plans.

Objective: Specific promoters could improve efficiency and ensure the safety of gene therapy. The aim of our study was to screen examples for lung cancer. Methods: The firefly luciferase gene was used as a reporter, and promoters based on serum markers of lung cancer were cloned. The activity and specificity of seven promoters, comprising CEACAM5 (carcinoembryonic antigen, CEA), GRP (Gastrin-Releasing Peptide), KRT19 (cytokeratin 19, KRT), SFTPB (surfactant protein B, SP-B), SERPINB3 (Squamous Cell Carcinoma Antigen, SCCA), SELP (Selectin P, Granule Membrane Protein 140kDa, Antigen CD62, GMP) and DKK1 (Dickkopf-1) promoters were compared in lung cancer cells to obtain cancer-specific examples with strong activity. Results: The CEACAM5, DKK1, GRP, SELP, KRT19, SERPINB3 and SFTPB promoters were cloned. Furthermore, we successfully constructed recombinant vector pGL-CEACAM5 (DKK1, GRP, SELP, KRT19, SERPINB3 and SFTPB) contained the target gene. After cells were transfectedwith recombinant plasmids, we found that the order of promoter activity from high to low was SERPINB3, DKK1, SFTPB, KRT19, CEACAM5, SELP and GRP and the order for promoters regarding specificity and high potential were SERPINB3, DKK1, SELP, SFTPB, CEACAM5, KRT19 and GRP. Conclusion: The approach adopted is feasible to screen for new tumour specific promoters with biomarkers. In addition, the screened lung-specific promoters might have potential for use in lung cancer targeted gene therapy research.

Immunohistochemical stains for RB and p53 tumor suppressor gene products were performed on 72 cases of resected primary lung cancer tissues to study the correlation between their expressions and the histologic types, the clinical stage, and the survival rate. The results were as follows. 1. The RB protein was altered or absent in 38 cases (52.8%), and the mutant p53 protein was detected in 35 cases (48.6%). 2. The incidences of RB and p53 protein expression were significantly different among the histologic types (p＜0.05) but were not correlated with the clinical stages of lung cancer (p＞0.05). 3. The two year survival rate of patients with alteration of both RB and p53 genes (RB-/p53＋) was 22. 4%, and that with no alteration of both genes (RB+/p53-) was 63.1%. This difference was statistically significant (p=0.01). 4. It was shown that alteration of RB protein greatly affects the prognosis of lung carcinoma by multivariate analysis of prognostic factors. The presence or absence of RB and mutant p53 protein in tumor cells is closely related to the survival of primary lung cancer patients, and it is suggested that RB gene expression is an independent prognostic factor of primary lung cancer.
