Objectives: The purpose of this study was to evaluate for prognostic significance of VEGF expression and tumor angiogenesis in papillary carcinomas of the thyroid. Materials and Methods: The materials were 79 cases of papillary thyroid carcinomas, and age, sex, tumor size, multiplicity of tumor, capsular invasion, lymph node metastasis, recurrence, TNM stage, DeGroot stage and AMES scale were evaluated. An immunohistochemical stains for CD 34 to estimate microvessel density (MVD), and VEGF were done. MVD was defined as an average count of vessels per ×400 power field in the most vascularized area. VEGF expression was interpreted as 1+ and 2+ according to staining intensity and percentages of positive cells. Results: Mean score of MVD was 39.7±16.9. MVD were significantly higher in cases with capsular invasion (p=0.0001), lymph node metastasis (p=0.0001), TNM stage III (p=0.0022), DeGroot stage III (p=0.0163) and high risk group by AMES scale (p=0.0001). VEGF 2+ expression rate was significantly increased in cases with capsular invasion and lymph node metastasis (p=0.0006, p=0.0013), and in cases with TNM stage III, DeGroot stage III and high risk group by AMES scale (p=0.0236, p=0.0003, p=0.0293). In VEGF 2 + expression group, MVD was significantly higher than in VEGF 1 + group (p=0.0008), and MVD showed positive relation to VEGF 2 + expression (r=0.4616). Conclusion: VEGF expression and high MVD were significantly correlated to capsular invasion, lymph node metastasis, TNM stage III, DeGroot stage III and high risk group by AMES scale. The expression of VEGF and high MVD could be considered to be one of prognostic factor in papillary thyroid carcinomas.

심재성 낭종성 직장염의 수술적 치료 1례 : Surgical treatment of proctitis cystica profunda
강헌대,배기범,신진용,홍관희 白中央醫療院 2004 仁濟醫學 Vol.25 No.1
Proctitis cystica profunda (PCP) is a rare benign disease of the colon and rectum in which mature glandular epithelium extends into the tissue beneath the muscularis mucosa. It is important that the lesion be differentiated from a mucinous adenocarcinoma. Patients with this condition usually present with a palpable rectal mass, tenesmus and bloody mucoid diarrhea. The diagnosis is suspected usually on the basis of clinical symptoms, endoscopic appearance and histology. Definite diagnosis is made histopathology. The histologic findings are usually typical and it may be possible to differentiate this disorder from malignancy on tissue biopsy. In cases of the difficulty of histologic confirmation, more extirpative excision may be considerd. We report one case of proctitis cystica profunda managed surgically.
