抄録 Struma ovarii is a rare neoplasm that accounts for approximately 0.3オ of ovarian tumors. Due to its ultrasound morphology, which is quite similar to that of malignant ovarian carcinoma, most struma ovarii cases are open operated with laparotomy rather than laparoscopy. We present 3 cases of struma ovarii, which were diagnosed preoperatively by imaging studies and removed by laparoscopic surgery. All patients were premenopausal women between ages 31‒50. The magnetic resonance imaging (MRI) findings were complex masses composed of multiple cysts and solid components with T2-hypointense regions as well as multiple T1-hyperintense cystic areas, findings that are typical for struma ovarii. A combination of plain computed tomography (CT), positron emission tomography (PET)-CT, and scintigraphy was useful for diagnosis. Laboratory examination revealed elevated serum thyroglobulin, which led to the diagnosis of struma ovarii. Laparoscopic surgeries were performed without rupturing the tumors. Although it has been difficult to differentiate between struma ovarii and malignant tumors by conventional methods, recently MRI techniques appear make it possible to diagnose struma ovarii preoperatively from the abovementioned imaging characteristic, together with laboratory data. As for treatment, we think laparoscopy could be successful for struma ovarii, but the surgeon must be careful not to rupture the tumor intra-abdominally in order to prevent dissemination, which could lead to malignancy.

抄録 The purpose of this study was to evaluate prognostic factors for epithelial ovarian cancer. We found that the pretreatment values of maximum standardized uptake (SUVmax) of the primary tumor by positron emission tomography/computed tomography (PET/CT), tumor marker CA125 and C-reactive protein (CRP) were correlated with clinical characteristics and prognosis for such patients. The clinical parameters and prognoses and their correlations with SUVmax of primary tumor, CA125 and CRP were examined for 51 patients with primary ovarian cancer. The SUVmax of the primary tumor had a statistically significant association with stage (p=0.010) and histology (p=0.001). CA125 was significant associated with stage (p=0.011), histology (p=0.005) and lymph node metastasis (p=0.025). CRP was also significantly associated with stage (p=0.049). Disease-free survival rates of patients exhibiting a high SUVmax, CA125 and CRP were significantly lower than those exhibiting a low SUVmax, CA125 and CRP levels (p=0.008, 0.034, and 0.037, respectively). Furthermore, overall survival rates of patients exhibiting a high SUVmax were significantly lower than those exhibiting a low SUVmax (p=0.049).The high SUVmax of primary tumor is an important factor for identifying ovarian cancer patients with a predictor for poor prognosis.

抄録

The insulin-like growth factor I receptor (IGF-IR) is exceptionally overexpressed in many cervicalcancer-derived cell lines. It is postulated that a decrease of p53 protein levels due to human papillomavirus (HPV) infection may contribute to the up-regulation of IGF-IR expression in cervical cancer cells because transcription of IGF-IR is strictly down-regulated by p53. To evaluate this fact in clinical cervical cancer specimens, we checked the expression levels and activated status of IGF-IR by immunohistochemistry. Formalin-fixed and paraffin-embedded specimens obtained by conization or hysterectomy were stained with anti-IGF-IR and with an antibody recognizing phosphorylated tyrosine at its c-terminus. The expression levels of IGF-IR were significantly high in cervical intraepithelial neoplasia (CIN) III and invasive cancer specimens. Phosphorylation of IGF-IR was promoted in all CIN and invasive cancer specimens, and its intensity was related to the promotion of lesions. Interestingly, IGF-IR overexpression was missing in the basal layer of CIN I and II lesions, whereas it was evenly distributed in CIN III and invasive cancer lesions. This IGF-IR overexpression pattern may be utilized in the diagnosis of HPV infection status in CIN lesions.
