ABSTRACT
OBJECTIVE: Adult-type granulosa cell tumors (GCT) are sex cord-stromal tumors and often accompanied with abdominal distention and hyperestrogenism-related symptoms. Adult-type GCT-presenting ascites and pleural effusion is extremely rare. CASE REPORT: A 56-year-old perimenopausal woman presented with abdominal distention and abnormal vaginal spotting. Ultrasound and abdominal computed tomography showed a complex cystic mass in the left ovary accompanied with bilateral pleural effusion and ascites. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, left pelvic lymph node dissection, omentectomy and appendectomy. Final histopathological diagnosis was adult-type GCT. The patient had postoperative hormone and anti-angiogenesis agent therapy with free of disease. CONCLUSION: Ovarian cystic complex mass accompanied with ascites and pleural effusion often results from malignant ovarian tumors or benign ovarian fibroma. Based on the aforementioned report, the rare types of ovarian tumors, such as adult-type granulosa cell tumor of the ovary should be taken into consideration.

Frontline intraperitoneal chemotherapy (IPCT) in the treatment of epithelial ovarian cancer has been well established. However, the role of second-line IPCT is yet to be confirmed. With a view to implementing IPCT to treat recurrent disease, a prerequisite is to perform a cytoreductive procedure to minimize residual tumor size. However, the role of cytoreductive procedure is still in debate due to a higher chance of complications. A matched retrospective cohort study was conducted. From 2008 to 2015, we adopted a relatively simple and safe tumor drilling technique to maximize tumor exposure to second-line IPCT. Patients who received tumor drilling followed by second-line IPCT constituted the cohort group. Concurrently, patients who received standard second-line systemic chemotherapy were selected as the comparison group. After propensity score matching, 85 patients in each group entered into the final analysis. The median progression-free survival was 7.3 months (95% confidence interval [CI], 6.2-7.8) for the cohort group versus 4.1 months (95% CI, 4.0-4.3) for the comparison group (hazard ratio = 0.25 [95% CI, 0.17-0.36]; P < .001, by log-rank test). The median overall survival was 33.6 months (32.1-36.6) for the cohort group versus 25.9 months (20.5-26.9) for the comparison group (hazard ratio = 0.33 [95% CI, 0.23-0.48]; P < .001, by log-rank test). Toxicities in the cohort group were not different from those that were published in reports of IPCT for ovarian cancer. The most commonly observed toxicity was gastrointestinal origin (51.7%), and it may be attributed to the intraperitoneal pharmacokinetic clearance of cisplatin and taxol and we also discussed the mechanism of gastrointestinal toxicity. Tumor drilling followed by second-line IPCT may confer a survival advantage over standard second-line systemic chemotherapy in the treatment of recurrent ovarian cancer.

Here we report a case of type A thymoma with adenoid cystic pattern, which extended to the lower anterior neck and clinically mimicked a nontoxic thyroid goiter. The cytologic smears of fine-needle aspiration showed cohesive fragments of short spindle cells with finely granular chromatin and inconspicuous nucleoli. Scant interspersed lymphocytes were present. On air-dried Liu stained preparation, there were many magenta-colored hyaline globules wrapped by spindle tumor cells. The cytomorphologic findings correlated with the adenoid cystic pattern in histology. The cytologic differential diagnosis and the prognostic aspects of type A thymoma were briefly discussed.

Background. All published reports concerning secondary cytoreductive surgery for relapsed ovarian cancer have essentially been observational studies. However, the validity of observational studies is usually threatened from confounding by indication. We sought to address this issue by using comparative effectiveness methods to adjust for confounding. Methods. Using a prospectively collected administrative health care database in a single institution, we identified 1,124 patients diagnosed with recurrent epithelial, tubal, and peritoneal cancers between 1990 and 2009. Effectiveness of secondary cytoreductive surgery using the conventional Cox proportional hazard model, propensity score, and instrumental variable were compared. Sensitivity analyses for residual confounding were explored using an array approach. Results. Secondary cytoreductive surgery prolonged overall survival with a hazard ratio (95% confidence interval) of 0.76 (range 0.66-0.87), using the Cox proportional hazard model. Propensity score methods produced comparable results: 0.75 (range 0.64-0.86) by nearest matching, 0.73 (0.65-0.82) by quintile stratification, 0.71 (0.65-0.77) by weighting, and 0.72 (0.63-0.83) by covariate adjustment. The instrumental variable method also produced a comparable estimate: 0.75 (range 0.65-0.86). Sensitivity analyses revealed that the true treatment effects may approach the null hypothesis if the association between unmeasured confounders and disease outcome is high. Conclusions. This comparative effectiveness study provides supportive evidence for previous reports that secondary cytoreductive surgery may increase overall survival for patients with recurrent epithelial, tubal, and peritoneal cancers.

BACKGROUND/AIMS: Hepatitis B virus (HBV) levels correlate with the development of hepatocellular carcinoma (HCC), but the role of viral load in HCC recurrence after tumor resection remains unclear. Herein we aimed to investigate the role of viral load in HCC recurrence following tumor resection. METHODS: From 1990 to 2002, 193 HBV-related HCC patients who underwent tumor resection in Taipei Veterans General Hospital were enrolled. Serum HBV DNA level and mutations were analyzed for association with early and late recurrence, together with other clinical variables. RESULTS: During a follow-up of 58.2+/-44 months, 134 patients had HCC recurrence. Multivariate analysis showed that multinodularity (Hazard ratio [HR], 95% confidence interval [CI]; 2.232, 1.021-4.878), macroscopic venous invasion (4.693, 1.645-13.391), AFP >20 ng/ml (3.891, 1.795-8.475), and cut margin

Endodermal sinus tumor, also known as yolk sac tumor, is a rare malignant ovarian tumor that usually occurs in the second decade of life. Here, we report a case of endodermal sinus tumor which occurred in a 14-year-old girl. She presented with lower abdominal pain for about 4 months. Initial ultrasound findings revealed a large ovarian multilocular solid tumor. Doppler study revealed multiple arteriole vessels running in the solid section of the tumor from which the lowest resistance index of 0.30 was recorded. The lactate dehydrogenase level was 261 U/L, and alpha-fetoprotein marker was 131,630 ng/mL. Axial contrast-enhanced T1-weighted magnetic resonance imaging showed a large cystic mass with solid components in the peripheral portions of the mass. The peripheral solid portions showed strong enhancement, indicating their hypervascularity. She received staging operation for malignant ovarian tumor, and the pathology reports revealed ovarian malignance of endodermal sinus tumor with omental invasion, stage IIIc. This case report suggests that in an adolescent female with elevated alpha-fetoprotein, low resistance index in the tumor mass and hypervascularity on contrast-enhanced T1-weighted magnetic resonance image, the probability of an endodermal sinus tumor should be highly suspected preoperatively.

OBJECTIVE: This study was done to evaluate the efficacy of the Pap smear, speculoscopy, and a combination of Pap smear and speculoscopy (PapSure examination) in pre- and postmenopausal women. STUDY DESIGN: All women were screened using the Pap smear and speculoscopy and combination of both (PapSure examination) in the multicenter trial. Final diagnosis of each patient was based on a histological evaluation of the colposcopic target biopsy. Results were analyzed using a proportional comparison test, sensitivity, specificity, and predictive value with significance determined at p<0.05. RESULTS: Of 1813 women screened, 1701 were eligible for analysis. Two hundred and fourteen women (12.6%) received at least one positive screening test result. Of the 1084 colposcopic biopsy specimens obtained, 24 showed low-grade squamous intraepithelial lesion (LSIL) and 19 high-grade SIL (HSIL). HSIL were considered test-positive. Rate of colposcopy was 21.5% (125/582) in the premenopausal group and 63.9% (321/502) in the postmenopausal group (p<0.001). For premenopausal women, speculoscopy (75.0%) or PapSure (91.7%) provided higher sensitivity than Pap smear (50%) (p<0.05). In postmenopausal women, no statistical significance in sensitivity existed between PapSure (85.7%) and Pap smear (57.1%). Speculoscopy (96.8%) or PapSure (96.5%) had lower specificity than Pap smear (99.6%) (p<0.001). CONCLUSION: PapSure was an accurate alternative screening method to Pap smear or speculoscopy for cervical intraepithelial lesions because of a significantly higher sensitivity along with adequate specificity for premenopausal women; however, PapSure was not a more effective cervical screening method for postmenopausal women.

OBJECTIVE: Aberrant glycosylation occurs in essentially all types of experimental and human cancers, and many glycosyl epitopes constitute tumor-associated antigens (for example, CA125). Many recent studies have indicated that some, if not all, aberrant glycosylation is a result of altered sialyltransferase (ST) expression; however, there is little known of the role of the altered mRNA expression of ST in ovarian cancers. METHODS: Alterations in ST mRNA expression in postmenopausal ovarian tissues, including those of normal controls (n=24) and malignant serous ovarian cancers (n=24), were examined by means of real-time quantitative reverse transcription-polymerase chain reaction (RTQ-PCR). Maackia Amurensis Agglutinin type 2 (MAA) specific foralpha2,3-linked NeuNAc was used for immunohistochemical staining. RESULTS: Among these five STs, the mRNA expressions of three STs, including ST3Gal III, ST3Gal IV, and ST3Gal VI, were significantly decreased in patients with ovarian cancers, compared to the normal controls (P<0.001). By contrast, the mRNA expressions of ST3Gal I and ST6Gal I were increased in ovarian cancer tissues, compared to those of the normal controls (P<0.001). The ovarian epithelial carcinoma part showed strong positivity for MAA, whereas MAA staining in the stromal part was negative. Both the epithelial part and the stromal part of postmenopausal ovarian tissue showed negativity for MAA staining. However, clinico-pathological parameters, including stage, differentiation, amount of ascites, and serum levels of CA125, did not show any correlation to mRNA expression of any given-type ST. CONCLUSIONS: Our results suggest that altered mRNA expressions of alpha2,3-sialyltransferase ST3Gal I, ST3Gal III, ST3Gal IV, ST3Gal VI, andalpha2,6-sialyltransferase ST6Gal I are of importance in malignant ovarian cancers. An increased expression of ST3Gal I may contribute directly to increased alpha2,3-linked sialylation in ovarian serous carcinoma.
