Angioleiomyoma is a benign tumour arising from the vascular smooth muscle of blood vessel walls. It usually occurs in the lower extremities of females as a slow-growing, firm and occasionally painful mass. Only 8.5~10% of angioleiomyoma have been reported to occur on the head and neck area. Furthermore, to the best of our knowledge only 9 cases of angioleiomyoma have been reported to occur on the ear. Herein, we report a case of angioleioyoma in a 66 year-old woman who presented with a 4 year history of a painless, nontender nodule on the anti-helix of the ear, an unusual site of occurrence.

PURPOSE: Combined chemoradiotherapy is standard management for locally advanced non-small cell lung cancer (LA-NSCLC), but standard treatment for elderly patients with LA-NSCLC has not been confirmed yet. We evaluated the feasibility and efficacy of concurrent chemoradiotherapy (CCRT) for elderly patients with LA-NSCLC. MATERIALS AND METHODS: Among patients older than 65 years with LA-NSCLC, 36 patients, who underwent CCRT were retrospectively analyzed. Chemotherapy was administered 3-5 times with 4 weeks interval during radiotherapy. Thoracic radiotherapy was delivered to the primary mass and regional lymph nodes. Total dose of 54-59.4 Gy (median, 59.4 Gy) in daily 1.8 Gy fractions and 5 fractions per week. RESULTS: Regarding the response to treatment, complete response, partial response, and no response were shown in 16.7%, 66.7%, and 13.9%, respectively. The 1- and 2-year overall survival (OS) rates were 58.2% and 31.2%, respectively, and the median survival was 15 months. The 1- and 2-year progression-free survivals (PFS) were 41.2% and 19.5%, respectively, and the median PFS was 10 months. Regarding to the toxicity developed after CCRT, pneumonitis and esophagitis with grade 3 or higher were observed in 13.9% (5 patients) and 11.1% (4 patients), respectively. Treatment-related death was not observed. CONCLUSION: The treatment-related toxicity as esophagitis and pneumonitis were noticeably lower when was compared with the previously reported results, and the survival rate was higher than radiotherapy alone. The results indicate that CCRT is an effective in terms of survival and treatment related toxicity for elderly patients over 65 years old with LA-NSCLC.

BACKGROUND: Thymidine phosphorylase (TP) is an enzyme catalyzing the reversible phosphorolysis of thymidine to thymine and 2-deoxyribose-1-phosphate. TP plays a role in angiogenesis. Evidences suggest that infiltrating inflammatory cells adjacent cancer cells may affect tumor cell behavior. To evaluate each of these significances of TP expression in cancer cell and cancer-infiltrating inflammatory cells, we investigated TP expression patterns in cancer cells and infiltrating inflammatory cells adjacent cancer cells separately and the relationship between TP expression and angiogenesis or survival. METHODS: Immunohistochemistry assays were performed with anti-TP monoclonal antibody (Roche Japan) and anti-factor VIII polyclonal antibody (Dako) on 92 paraffin-embedded tissue samples from stomach cancer patients. A single pathologist scored the slides for percent positivity of tumor cells, intensity, localization and distribution of expression. TP reactivity in tumor cells (cancer) and infiltrating mononuclear cells adjacent cancer cells (matrix) was separately accessed. According to the pattern of TP expression, subjects were divided into 4 groups for further analysis: cancer(C;+)/matrix(M;+), cancer(+)/matrix(-), cancer(-)/matrix(+) and cancer(-)/matrix(-). With these 4 subsets of TP expression patterns, we evaluated cancer cell differentiation, intratumoral microvessel density, extent of tumor invasion, LN stage, and patient survival to find any differences among the subsets. RESULTS: Of 92 stomach cancer tissue, C/M(+/+), C/M(+/-), C/M(-/+), and C/M(-/-) were observed in 33patients, 19, 30, and 10, respectively. Microvessel density scores were higher in cancer(+)/matrix(-) group compared in cancer(-)/matrix(-) group (p=0.02). Of 4 TP expression subsets, other clinical factors such as histology, extent of tumor invasion, and LN metastasis were not associated with TP expression. CONCLUSION: This study suggested the TP in cancer-infiltrating inflammatory cell as well as cancer cells themselves may play an important role in angiogenesis as co-active factors in stomach cancer.

Tendon and ligament (T/L) have been known to be obviously different from each other in tissue level. However, due to the overlapping gene markers, distinction in cellular level has not been clearly verified yet. Recently, the use of nuclear magnetic resonance (NMR) spectroscopy has shown the potential to detect biological markers in cellular level. Therefore, in this study we applied a non-invasive technique based on NMR spectroscopy to establish biomarkers to distinguish between T/L fibroblasts. In addition the cellular morphologies and gene expression patterns were also investigated for comparison through optical microscopy and real-time polymerase chain reaction (PCR). No difference was observed from morphology and real-time PCR results, either as expected. However, we found clear differences in their metabolomic spectra using ¹H NMR spectroscopy. The calculated integral values of fatty acids (with chemical shifts at ~0.9, 1.26, 1.59, 2.05, 2.25, and 2.81 ppm), lactate (~1.33 ppm), and leucine (~2.72 ppm) were significantly different between the two types of fibroblasts. To be specific tendon group exhibited higher level of the metabolite than ligament group. In conclusion, in-cell metabolomic evaluation by NMR technique used in this study is believed to provide a promising tool in distinguishing cell types, especially T/L cells, which cannot be classified by conventional biological assays.

PURPOSE: Combined modality therapy including chemotherapy, surgery and radiotherapy is considered the standard of care for the treatment of stage III non-small cell lung cancer (NSCLC). This study was conducted to evaluate the efficacy of paclitaxel and cisplatin with induction chemotherapy followed by concurrent chemoradiotherapy for stage IIIB NSCLC. MATERIALS AND METHODS: Between July 2000 and October 2005, thirty-nine patients with stage IIIB NSCLC were treated with two cycles of induction chemotherapy followed by concurrent chemoradiotherapy. The induction chemotherapy included the administration of paclitaxel (175 mg/m2) by intravenous infusion on day 1 and treatment with cisplatin (75 mg/m2) by intravenous infusion on day 1 every 3 weeks. Concurrent chemoradiotherapy included the use of paclitaxel (60 mg/m2) plus cisplatin (25 mg/m2) given intravenously for 6 weeks on day 43, 50, 57, 71, 78 and 85. Thoracic radiotherapy was delivered with 1.8 Gy daily fractions to a total dose of 54~59.4 Gy in 6~7 weeks (median: 59.4 Gy). RESULTS: The follow up period was 6~63 months (median: 21 months). After the induction of chemotherapy, 41.0% (16 patients) showed a partial response and 59.0% (23 patients) had stable disease. After concurrent chemoradiotherapy, 10.3% (4 patients) had a complete response, 41.0% (16 patients) had a partial response, and the overall response rate was 51.3% (20 patients). The 1-, 2-, 3-year overall survival rates were 66.7%, 40.6%, and 27.4% respectively, with a median survival time of 20 months. The 1-, 2-, 3-year progression free survival rates were 43.6%, 24.6%, and 24.6%, respectively, with median progression free survival time of 10.7 months. Induction chemotherapy was well tolerated. Among 39 patients who completed the entire treatment including chemoradiotherapy, 46.3% (18 patients) had esophagitis greater than grade 3 and 28.2% (11 patients) had radiation pneumonitis greater than grade 3. CONCLUSION: Paclitaxel and cisplatin with induction chemotherapy followed by concurrent chemoradiotherapy for stage IIIB NSCLC seems to be an effective treatment. Occurrence of esophagitis and pneumonitis represents a significant morbidity and suggests a modification of the treatment regimen, either with the chemotherapy schedule or with radiotherapy treatment planning.

PURPOSE: We evaluated the effect of early chemoradiotherapy on the treatment of patients with limited stage small cell lung cancer (LS-SCLC). MATERIALS AND METHODS: Between January 2006 and December 2011, thirty-one patients with histologically proven LS-SCLC who were treated with two cycles of chemotherapy followed by concurrent chemoradiotherapy and consolidation chemotherapy were retrospectively analyzed. The chemotherapy regimen was composed of etoposide and cisplatin. Thoracic radiotherapy consisted of 50 to 60 Gy (median, 54 Gy) given in 5 to 6.5 weeks. RESULTS: The follow-up period ranged from 5 to 53 months (median, 22 months). After chemoradiotherapy, 35.5% of the patients (11 patients) showed complete response, 61.3% (19 patients) showed partial response, 3.2% (one patient) showed progressive disease, resulting in an overall response rate of 96.8% (30 patients). The 1-, 2-, and 3-year overall survival (OS) rates were 66.5%, 41.0%, and 28.1%, respectively, with a median OS of 21.3 months. The 1-, 2-, and 3-year progression free survival (PFS) rates were 49.8%, 22.8%, and 13.7%, respectively, with median PFS of 12 months. The patterns of failure were: locoregional recurrences in 29.0% (nine patients), distant metastasis in 9.7% (three patients), and both locoregional and distant metastasis in 9.7% (three patients). Grade 3 or 4 toxicities of leukopenia, anemia, and thrombocytopenia were observed in 32.2%, 29.0%, and 25.8%, respectively. Grade 3 radiation esophagitis and radiation pneumonitis were shown in 12.9% and 6.4%, respectively. CONCLUSION: We conclude that early chemoradiotherapy for LS-SCLC provides feasible and acceptable local control and safety.

BACKGROUND: This research is to find out the object of Medical Phone Counsel rational and satisfactory by investigating in local clinic the actual state of Medical Phone Counsel, which is a form of medical care between doctor and patient, and by grasping the difference of expectation and recognition between doctor and patient on Medical Phone Counsel which is one of the service items of Attending Physician Registration System which is to be put into effect in near future. METHODS: This research conducted a se7-administered questionnaire targeting all practitioners to the number of forty four who gave primary care in Kangnung city from August to September in 1999, and each twenty patients Per Practitioner. This research compared and analyzed the difference of recognition between doctor and patient on the following contents of Medical Phone Counsel ; General Characteristic, Frequency, Contents, Time, Satisfiability, For or Against the Medical Phone Counsel to be executed under Attending Physician Registration System and Expectations. RESULTS: The questionnaire for doctor had a 70.5% of response rate, and the one for patient 17.2%. The 40.7% of the practitioners took a Phone Counsel actively, the 55.6% took part in Phone Counsel passively and the rest 3.7% did not participate in it. The 74.2% of them took this counsel for less than three minutes. Regarding recognition on Phone Counsel, the 48.1% of them answered that they executed it as it is their duty and the 48.4% responded that they took it reluctantly in spite of their busy business. The 3.2% answered that it is not their duty. Among those in favor of Phone Counsel under Attending Physician (or Prime Doctor) Registration System, the 28.6% agreed as it is their own duty and the 71.4% was for it subject to economic compensation. While, the 62.9% of the patients answered that they had never experienced the Phone Counsel, and the 34.4% responded that they had experienced it one or two times in a yea. Among those who had experienced Phone Counsel, the 46.4% was satisfied with it. As far as the difference of expectation and recognition between doctor and patient on Medical Phone Counsel is concerned, only 45.2% of the practitioners were in favor of Medical Phone Counsel under the Attending Physician Registration System. While, the 70.1% among the patients was in favor of its execution. These two values showed a significant difference between doctor and patient (P<0.05), And the 83.9% of the practitioners insisted that the charge should be paid against Phone Counsel and only 56.2% of the patients insisted the same. There was also a significant difference between two values. (P<0.05) CONCLUSION: The practitioners were taking part in Medical Phone Counsel at any form. To the contrary, most of the patients were not. As far as the systematization of Phone Counsel is concerned, most of the practitioners had mental reluctance if there is no economic compensation. On the other hand, most of the patients had high expectation regardless of economic matters. If Medical Phone Counsel becomes systematized, it is expected that there will be a great trouble between its supply and demand.

PURPOSE: The effect of concurrent chemoradiotherapy was analyzed in elderly patients when used in the treatment of locally advanced esophageal cancer. MATERIALS AND METHODS: The retrospective analysis included 28 elderly patients aged 65 or older, with histopathologically confirmed squamous cell carcinoma of the esophagus, underwent concurrent chemoradiotherapy from January 2001 to July 2007. The squamous cell carcinoma disease stages included 8 patients (28.8%) in stage IIa, 10 patients (35.7%) in stage IIb, and 10 patients (35.7%) in stage III. Fractionated radiotherapy was performed with a 6 MV or 10 MV X-ray for 45~63 Gy (median: 59.4 Gy). Chemotherapy was applied concurrently with the initiation of radiotherapy. A 75 mg/m2 dose of Cisplatin was intravenously administered on day 1. Further, 5-FU 1,000 mg/m2 was continuously administered intravenously from days 1 to 4. This regimen was performed twice at 3-week intervals during radiotherapy. Two cycles of consolidation chemotherapy was performed after radiotherapy. RESULTS: The follow-up period was 3~72 months (median: 19 months). The treatment responses after concurrent chemoradiotherapy included a complete response in 11 patients (39.3%), a partial response in 14 patients (50.0%), and no response in 3 patients (10.7%). The overall response rate was 89.3% (25 patients). The overall 1-, 2- and 3-year survival rates were 55.9%, 34.6% and 24.2%, respectively. The median survival time was 15 months. Two-year survival rates of patients with a complete response, partial response, and no response were 46.2%, 33.0%, and 0%, respectively. The stage and tumor response after concurrent chemoradiotherapy were statistically significant prognostic factors related with survival. No treatment-related deaths occurred in this study. CONCLUSION: Concurrent chemoradiotherapy is a relatively effective treatment without serious complications in elderly patients with locally-advanced esophageal cancer.

OBJECTIVES: Several studies have investigated the effects of serum uric acid (SUA) levels on chronic kidney disease (CKD), with discrepant results. The effect of SUA levels on CKD development was studied in the Korean rural population. METHODS: A total of 9695 participants aged ≥40 years were recruited from 3 rural communities in Korea between 2005 and 2009. Of those participants, 5577 who participated in the follow-up and did not have cerebrovascular disease, myocardial infarction, cancer, or CKD at baseline were studied. The participants, of whom 2133 were men and 3444 were women, were grouped into 5 categories according to their quintile of SUA levels. An estimated glomerular filtration rate of < 60 mL/min/1.73 m2 at the time of follow-up was considered to indicate newly developed CKD. The effects of SUA levels on CKD development after adjusting for potential confounders were assessed using Cox proportional hazard models. RESULTS: Among the 5577 participants, 9.4 and 11.0% of men and women developed CKD. The hazard ratio (HR) of CKD was higher in the highest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.60; 95% confidence interval [CI], 1.02 to 2.51) and women (adjusted HR, 1.56; 95% CI, 1.14 to 2.15). Furthermore, CKD development was also more common in the lowest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.83; 95% CI, 1.15 to 2.90). The effect of SUA was consistent in younger, obese, and hypertensive men. CONCLUSIONS: Both high and low SUA levels were risk factors for CKD development in rural Korean men, while only high levels were a risk factor in their women counterparts.
