BACKGROUND: So far there's no tumor maker applied in diagnosis and treatment of thymic epithelial tumors. This study is to assess the correlation between serum cytokine 19 fragment (Cyfra 21-1) and clinicopathological features and prognosis of thymic epithelial tumors (TETs). METHODS: The clinical data of 159 patients with TETs in Shanghai Chest Hospital was retrospectively analysed. Patients were divided into groups according to different tumor stages and histotypes. Serum Cyfra 21-1 was thus compared. In addition, the possible relationship between perioperative serum Cyfra 21-1 level and the recurrent status was carrid out. RESULTS: Preoperative Cyfra 21-1 serum concentrations in patiants with advanced stage (T4) and thymic carcinomas were significantly higher than that in others (P<0.001, P<0.001, respectively). When the preoperative serum level exceeds the out-off of 1.66 ng/mL, it possibly indicates the recurrence during follow up. Furthermore, the sensitivity, specificity, and positive as well as negative predictive value (PPV and NPV) of postoperative Cyfra 21-1 to predict tumor recurrence were evaluated. At a cut-off of Cyfra 21-1 of 2.66 ng/mL, the sensitivity was 0.7, the specificity was 0.925, the PPV was 0.5 and the NPV was 0.966. CONCLUSIONS The elevated level of preoperative serum Cyfra 21-1 indicates an advanced stage of tumor or a more malignant histotype (thymic carcinoma). It also probably suggests a higher risk of tumor recurrence. During the oncological follow up, in addition to regular imaging examinations, the blood test of serum Cyfra 21-1 is also suggested to improve the diagnosis of tumor recurrence in order to improve the prognosis.

This study is a multi-center clinical study, which aimed to compare CA125, HE4, and risk of ovarian malignancy algorithm (ROMA) in predicting epithelial ovarian cancer of Korean women with a pelvic mass. Prospectively, serum from 90 Korean women with ovarian mass was obtained prior to surgery. For control group, serum from 79 normal populations without ovarian mass was also obtained. The HE4 and CA125 data were registered and evaluated separately and ROMA was calculated for each sample. Total 67 benign tumors and 23 ovarian cancers were evaluated. Median serum levels of HE4 and CA125, and ROMA score were significantly higher in patients with ovarian cancer than those with benign ovarian tumor and normal population (P < 0.001). In ROC curve analysis for women with a pelvic mass, area under the curve (AUC) for HE4 and ROMA was higher than CA125. Statistical differences in each study compared to CA125 were marginal (P compared to CA125; 0.082 for HE4 and 0.069 for ROMA). Sub-analysis revealed that AUC for HE4 and ROMA was higher than AUC for CA125 in post-menopausal women with a pelvic mass, but there were no statistically significant differences (P compared to CA125; 0.160 for HE4 and 0.127 for ROMA). Our data suggested that both HE4 and ROMA score showed better performance than CA125 for the detection of ovarian cancer in women with a pelvic mass. HE4 and ROMA can be a useful independent diagnostic marker for epithelial ovarian cancer in Korean women.

OBJECTIVE: The purpose of this study was to evaluate the expression of epidermal growth factor-like domain 7 (EGFL7) in epithelial ovarian cancer, and to assess its relevance to clinicopathological characteristics and patients' survival. METHODS: A total of 177 patients with epithelial ovarian cancer were enrolled in the current study. For each patient, a retrospective review of medical records was conducted. Immunohistochemical staining for EGFL7 was performed using tissue microarrays made with paraffin-embedded tissue block. EGFL7 expression levels were graded on a grade of 0 to 3 based on the percentage of positive cancer cells. We analyzed the correlations between the expression of EGFL7 and various clinical parameters, and also analyzed the survival outcome according to the EGFL7 expression. RESULTS: The expression of EGFL7 in ovarian cancer tissues was observed in 98 patients (55.4%). High expression of EGFL7 (grade 2 or 3) was significantly correlated with pathologic type, differentiation, stage, residual tumor after debulking surgery, lymphovascular space involvement, lymph node metastasis, high cancer antigen 125, peritoneal cytology, and ascites. Among these clinicopathologic factors, differentiation was significantly correlated with EGFL7 expression in multivariate analysis (p<0.05). Survival analysis showed that the patients with high EGFL7 expression had a poorer disease free survival than those with low EGFL7 expression (p=0.002). CONCLUSION: Our data suggest that EGFL7 expression is a novel predictive factor for the clinical progression of epithelial ovarian cancer, and may constitute a therapeutic target for antiangiogenesis therapy in patients with epithelial ovarian cancer.

OBJECTIVE: Fertility-sparing surgery (FSS) is becoming an important technique in the surgical management of young women with early-stage epithelial ovarian cancer (EOC). We retrospectively evaluated the outcome of laparoscopic FSS in presumed clinically early-stage EOC. METHODS: We retrospectively searched databases of patients who received laparoscopic FSS for EOC between January 1999 and December 2012 at Samsung Medical Center. Women aged < or =40 years were included. The perioperative, oncological, and obstetric outcomes of these patients were evaluated. RESULTS: A total of 18 patients was evaluated. The median age of the patients was 33.5 years (range, 14 to 40 years). The number of patients with clinically stage IA and IC was 6 (33.3%) and 12 (66.7%), respectively. There were 7 (38.9%), 5 (27.8%), 3 (16.7%), and 3 patients (16.7%) with mucinous, endometrioid, clear cell, and serous tumor types, respectively. Complete surgical staging to preserve the uterus and one ovary with adnexa was performed in 4 patients (22.2%). Two out of them were upstaged to The International Federation of Gynecology and Obstetrics stage IIIA1. During the median follow-up of 47.3 months (range, 11.5 to 195.3 months), there were no perioperative or long term surgical complications. Four women (22.2%) conceived after their respective ovarian cancer treatments. Three (16.7%) of them completed full-term delivery and one is expecting a baby. One patient had disease recurrence. No patient died of the disease. CONCLUSION: FSS in young patients with presumed clinically early-stage EOC is a challenging and cautious procedure. Further studies are urgent to determine the safety and feasibility of laparoscopic FSS in young patients with presumed clinically early-stage EOC.
