ObjectiveTo evaluate the clinicopathologic characteristics and prognostic factors of ovarian granulosa cell tumors.MethodsMedical records of 113 patients presenting between January 1995 and December 2007 were retrospectively reviewed.ResultsOne-hundred two patients had adult type disease, with a mean age of 46.2 years (range, 18 to 83 years) and a mean follow-up period of 54.7 months (range, 1 to 155 months). The distribution of FIGO stages was 86 patients at stage I, 11 at stage II, and 5 at stage III. During follow-up, ten patients recurred at a mean time of 48 months (range, 4 to 109 months). Among them, three patients died after a mean of 57 months (range, 25 to 103 months). In recurrence analysis, advanced stage (p=0.032) and presence of residual disease (p=0.012) were statistically significant, and age<40 years, premenopause and positive washing cytology were marginally significant (p<0.1). In multivariate analysis, stage was the only factor associated with recurrence; adjuvant chemotherapy and fertility-sparing surgery were not statistically significant. Among 36 patients with fertility-sparing operations, eight patients had nine pregnancies and delivered seven babies. Eleven patients had juvenile type tumors; the mean age was 20.0 years (range, 8 to 45 years) and the mean follow-up period was 69.8 months (range, 20 to 156 months). The distribution of FIGO stage was nine patients at stage I and two at stage III. There were no recurrences or deaths reported. Four patients had seven pregnancies and delivered six babies.ConclusionStage is the only factor associated with disease-free survival, and fertility-sparing surgery may be a treatment option for women with early-stage disease who want to retain fertility.

Laparoscopic radical hysterectomy is a feasible and safe treatment modality in early and even locally advanced cervical cancer without decreasing survival. Surgical outcome was improved with experience, and the complication rate related to operation of group 1 was higher than that of group 2. There was no significant difference in survival between the 2 groups.

In endometrial endometrioid adenocarcinoma (EEC), the depth of myometrial invasion (MI) is an important parameter for determining whether additional treatment is warranted. The present study investigated the association between MI patterns, cancer stem cell (CSC) phenotypes, and their clinicopathological significance in EEC. A total of 73 cases of EEC with MI were examined in this study. Haematoxylin and eosin-stained tissue specimens were analysed for MI pattern, which was categorised as infiltrating; expansile; adenomyosis (AM)-like; or microcystic, elongated, and fragmented (MELF)-type. The expression of CSC markers such as cluster of differentiation (CD)44, CD133, and Nanog1, as well as oestrogen receptor (ER) and progesterone receptor (PR) was examined by immunohistochemistry. Clinicopathological features including age, DOI, MI pattern, LVI, lymph node (LN) metastasis, disease progression, and survival outcome were recorded. Most examined cases (45/73) were International Federation of Gynecology and Obstetrics (FIGO) stage I. MI showed infiltrating (49.3%), AM-like (26.3%), MELF (15.1%), and expansile (9.6%) patterns. Tumours with the infiltrating pattern were associated with high FIGO grade (P = 0.002), reduced ER and PR, and CD44 expression (P = 0.014, 0.026, and 0.030, respectively); those with a MELF pattern showed LN metastasis (P < 0.001), lymphovascular invasion (P = 0.011), and reduced ER, CD44, and CD133 expression (P = 0.036, 0.006, and 0.016, respectively). EEC with infiltrating/MELF patterns of MI is associated with worse prognosis. These results suggest that CSC expression profiles are an unfavourable indicator of EEC.
