BACKGROUND: It has been reported that younger patients with lung cancer have characteristic features that differ from those in older patients. The prognosis for young patients with this disease is controversial. This study aimed to determine the clinicopathological characteristics, the survival rate, and the risk factors associated with the overall survival rate in younger patients with lung cancer. METHODS: The records of 120 young(age≤40) patients with histologically confirmed lug cancer in the Korea Cancer Center Hospital(KCCH) between Jan. 1992 to 1998, 120 older(age>40) patients were randomly selected as the controls. RESULTS: More female patients(45.0% vs. 20.0%, p<0.001) and more adenocarcinoma cases(64.2% vs. 38.3%, p<0.001) were found in the younger group, when compared to the older patients. In NSCLC, advanced disease(stage III B and IV) was more common in the younger patients(90.2%) than in the older patients(62.7%) (p<0.001). The Median survival was 8.6 months in the younger patients and 12.2 months in the older(p=0.003). In a multivariate analysis, only the advanced-stage was an independent negative prognostic factor. CONCLUSION: Lung cancer in the younger age group presents with a more advanced stage resulting in a poor survival rate, which suggests that lung cancer in this population is more aggressive than in older patients.

Atopic dermatitis is an well-known skin disease showing inflammatory, chronically relapsing, non-contagious and pruritic symptoms. The aims of this study were to investigate the effects of Liriope platyphylla (LP) on atopic dermatitis of NC/Nga mice. To achieve this, NC/Nga mice were treated with four different conditions including vehicle, phthalic anhydride (PA), PA+5% LP and PA+10% LP, and the changes of immune-related factors were detected after 2 weeks. The pathological phenotypes of atopic dermatitis such as erythema, ear thickness, edema, scab and discharge were significantly decreased in PA+10% LP cotreated groups compare to PA treated group. Also, the weight of lymph node and thymus in immune organs were gradually decreased in LP treated groups, while the weight of spleen was slightly increased in same group. Furthermore, toluidine blue staining analysis, a method used to specifically identify the mast cell, showed that the decrease of master cell infiltration into the dermis were statistically observed in PA+5% LP and PA+10% LP5% cotreated groups. Especially, the decrease of IgE concentration was detected only PA+10% LP cotreated group, although this level was maintained in PA+5% LP cotreated group. Therefore, these results suggested that the water extracts of LP may contribute the relieve of atopic dermatitis symptoms and be considered as an excellent candidate for a atopic dermatitis-therapeutic drug.

Ultraviolet (UV) irradiation is an environmental factor that causes skin aging, and is also a major factor leading to cumulative alterations of skin structure, function and appearance. To investigate the effects of Selenium (Sel) on UV-induced skin aging, hairless mice were treated for 4 weeks with UV irradiation and topical application of Sel. Then, the effects of Sel were measured in the skin of these mice via histological analysis and Western blotting. According to the results of wrinkle formation analysis, the topical application of Sel induced a reduction in wrinkling formation in the damaged skin of the UV-irradiated mice. Additionally, our histological analysis demonstrated that the skin thickness in the Sel-treated group was less than in the UV-irradiated group. Furthermore, in an effort to investigate the mechanisms underlying the effects of Sel, the expression levels of matrix-metalloproteinase (MMP) and MAPK protein were assessed in both groups. The application of Sel induced a reduction in MMP-1 expression levels to the levels observed in the non-irradiated group. However, the expression level of MMP-9 was increased slightly in the Sel application group as compared with the vehicle application group. Additionally, the levels of ERK phosphorylation were increased by the application of Sel, but the levels of JNK and p38 were not altered by Sel treatment. These results suggest the possibility that Sel should be considered as a skin aging-protective and therapeutic drug candidate, which functions via the regulation of MMP expression levels.

Spontaneous regression may occur in malignancies such as hypernephroma, neuroblastoma, malignant melanoma, choriocarcinoma, and bladder tumor, but yet it is extremely rare in carcinoma of the stomach. So far, 19 cases have been reported in the English literature and the mechanisms underlying this intriguing phenomenon remain unknown. A 48-year-old man with histologically-verified advanced gastric carcinoma had received no treatment since its diagnosis. However, gastric carcinoma was no longer detectable by endoscopy and histology after 4 years. Thus, we report a case of spontaneous regression of carcinoma of the stomach with a brief review of relevant literatures.

Breast cancer is a common malignancy in women and frequently metastasizes to various organs such as liver, lung, brain, bone and so on. But metastasis to gastrointestinal tract is rare. We describe a 73-year-old woman with small intestinal metastasis of breast cancer. She was diagnosed as right breast cancer in stage I, received modified radical mastectomy 6 years ago and had been followed up without any evidence of residual disease. During investigation for lower abdominal pain and weight loss of 9 kg, we found a small bowel mass. The histology of the tissue taken from small bowel mass was adenocarcinoma, poorly differentiated. The immunohistochemical stain of this specimen showed 75% positivity of estrogen receptor and 90% positivity of progesterone receptor. This is a case of small bowel metastasis from breast cancer and we report this case with a review of literatures.

PURPOSE: The purpose of our study was to evaluate the outcome of intensified induction therapy using the Vanderbilt regimen in patients with a poor prognosis non-Hodgkin's lymphoma (NHL). MATERIALS AND METHODS: We retrospectively analyzed the results of two pilot studies, which enrolled the patients aged 60 years or less, with a previously untreated NHL of intermediate grade on the Working formulation, having 2 or 3 adverse prognostic factors on the age- adjusted International Prognostic Index. Patients received an intensified induction, with the regimen described by the Vanderbilt group. RESULTS: Thirty-five patients were analyzed. After induction, 29 patients (83%) achieved more than partial response (PR): 22 (63%) complete response (CR) and 7 (20%) PR. Three of the PRs were subsequently converted to CR following consolidation therapy. The overall CR rate, following the completion of treatment, was 71%. The 3-year overall survival (OS) rate of all patients was 53%. In the univariate analysis, age (

Extraskeletal Ewing's sarcomas (EES) are rare. Recently, Ewing's sarcoma of the bone, primitive neuroectodermal tumor (PNET), Askin tumor and EES have been included into the family of Ewing's tumors, due to the overlapping features relating to their clinico-pathological and cytogenetic appearance. We experienced a case of an EES arising from the duodenum in a 14-year-old girl who presented with hematemesis and epigastric discomfort. A duodenal biopsy specimen revealed the infiltration of small round cells and rich vasculatures, with immunohistochemical finding of MIC-2 (CD99) (+), vimentin (+), CD56 (NCAM) (+), LCA (-), T-cell (-), B-cell (-), CD43 (-) and CD68 (-). She was treated with several cycles of multiagent chemotherapy, and achieved an initial partial response, but rapid progression of tumor followed, so she was treated with surgical excision. This is the first case report of an EES arising from the duodenum in the literature.

BACKGROUND: Since the bioavailability of itraconazole capsule is influenced by patients gastric acidity, it results in treatment failure due to its low dissolution and subsequent low absorption when administered in fasting. Itraconazole Melt-Extrusion tablet has been lately developed in order to improve its dissolution profile. It is the first clinical study to evaluate the efficacy and safety of itraconazole Melt-Extrusion tablet in Korea. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of itraconazole melt-extrusion tablet 400mg daily for 1 week(pulse therapy) for hyperkeratotic type of tinea pedis and manus. METHODS: A clinical and mycological investigation was made of 812 outpatients with hyperkeratotic type of tinea pedis and/or tinea manus who had visited at 52 general hospitals under the lead of the Korean Dermatological Association from June to December, 1998. Patients confirmed by clinically and microscopically as hyperkeratotic type of tinea pedis and/or tinea manus were administered 2 tablets twice a day for one week and followed up for 8 weeks from the start of the medication. RESULTS: The results were summarized as follows; 1. Clinical symptoms of hyperkeratotic type of tinea pedis and/or tinea mauns were significantly improved at the end of study, week 8(p<0.001). 2. Clinical response rate, defined as more than 50% decrease of the sum of the clinical symptom scores, was 79.3%(512/646). 3. Mycological cure rate, dafined as both culture and KOH negative at week 8, was 78.2%(244 /312). 4. 40(5.5%) patients, of the 727 patients evaluable for drug safety evaluation, were reported to have adverse event. CONCLUSION: Itraconazole Melt-Extrusion tablet 400mg/day for 1 week (pulse therapy) is effective and safe in the treatment of hyperkeratotic type of tinea pedis and/or tinea manus.
