Granulocytic sarcoma.(chloroma) is a localized tumor mass composed of immature cells of the granulocytic series infiltrating an extramedullary site. The tumor may involve anywhere in the body, especially orbit, bone, epidural space and lymph node, but there is no case involved the esophagus. In a 34-year-old male presented with sudden anset of dysphagia, esophagoscopic examination revealed concentric narrowing of the esophageal lumen wirith alight granular mucosa in the midesophagus, which hiatologically proved to b a granulocytic sarcoma. Peripheral blood and bone marrow aspiration smears showed blastic crisis of chronic myelocytic leukemia. After the systemic chemotherapy, dysphagia and mid-esophageal luminal narrowing disappeared completely.

PURPOSE: To evaluate the effect of postoperative adjuvant radiation therapy and chemotherapy on the survival, pattern of failure and complication for locally advanced rectal carcinoma MATERIALS AND METHODS: From October 1992 to September 1995, twenty eight patients with rectal carcinoma were treated by postoperative adjuvant radiation therapy and chemotherapy. Radiation therapy was delivered with 6MV and 15MV linear accelerator, 180cGy fractions 5 day per week. Total radiation doses were 5040cGy in B2+3 and 5580cGy in C2+3. Within 4 weeks after radical surgery, 5-FU(400mg/m2/day) and Leucovorin(20mg/m2/day) were administered by intravenous injection for 4 days during the first and fifth week of radiation therapy. The median follow up was 19 months with a range 2 to 47 months. RESULTS: The 2 year overall survival and disease free survival rates were 78.6% and 70.8%, respectively. The 2 year overall survival was 93.0% in B2+3 and 76.2% in C2+3(p=0.11). The 2 year disease free survival was 79.4% in B2+3 and 69.2% in C2+3(p=0.13). The overall failure rate was 21.4%(6/28) including 10.7%(3/28) locoregional recurrence, 3.6%(1/28) distant metastasis and 7.1%(2/28) locoregional recurrence with distant metastasis. The overall locoregional recurrence rate was 17.9%(5/28). The 2 year locoregional recurrence rates were 13.3%(2/15) and 23.1%(3/13) for respectively for B2+3 and C2+3. The difference between the locoregional recurrence of B2+3 and C2+3 patients was not significant(p=0.07). Complications developed in 13 patients(46.4%), including 8 dermatitis, 7 loose stool, 6 leukopenia, 4 tenesmus, 2 diarrhea. In Univariate analysis, there was no statistically significant factor except for tumor grade in locoregional recurrence, disease free survival and overall survival rate(p=0.04, 0.05, 0.04). CONCLUSION: This study suggests that postoperative adjuvant radiation therapy and chemotherapy is effective in patients with locally advanced rectal cancer. Therefore these results need to be confirmed with a long term follow-up and larger number of patients with the further clinical trials including prospective controlled studies.

Three external quality assesment trials which composed of 16 control materials(12 chemical materials and four sets of microscopic photograph of urinary sediment) for interlaboratory quality control assesment in urinalysis were performed with 796, 823, and 841 participants, in each, in the year of 2009. The response rate were 97.1% (796/820), 95.5% (823/862) and 97.1% (841/866), in the first, the second and the third trials, in each. The test items include pH, glucose, protein, ketone, bilirubin, blood, urobilinogen, nitrite, leukocyte estrase, specific gravity and four microscopic photographs of urinary sediment. The survey results are summarized as follows: 1. The chemical quality control test in urinalysis revealed generally good concordance. 2. The percentage of using urinalysis analyzer was slightly decreased as 82.3% and the distribution of using reagent strip was similar to the previous year. 3. The percentage of response rate of microscopic photographs of urinary sediment was 83.5% (702/841) and the percentage of good performance of these tests ware 83.6% to 99.1%.
