Abstract
Background: Recently the use of “two tier" grading system in which ovarian serous carcinoma was classified as low-grade or high-grade in comparing to preceding system has improved authority in prognosis and survival. This approach is simplistic, reproducible, and based on biologic evidence. In this study, we reclassified ovarian serous carcinoma by a new two-tier system for grading and then evaluation of P53 expression in these tumors by immunohistochemistry method.
Methods: We retrospectively reviewed 32 cases of ovarian serous carcinoma with previous diagnosis of well differentiated (eight cases) and moderate to poorly differentiated serous carcinoma (24 cases) and according "two tier" grading system in low-grade vs. high-grade serous carcinoma reclassified. Subsequntly all cases immunostained by P53 marker. Also clinical data related to survival of patients (with or without recurrence of tumor and death) and paraclinical findings such as presurgical blood serum level of CA125 are gathered.
Results: Out of total eight patients with previously diagnosis well diferentiated serous carcinoma and of 24 patients with moderate to poorly differentiated serous carcinoma reclassified as low-grade and high-grade ovarian serous carcinoma respectively and a statistically significant difference was found between two groups. (P<0.005) Also of total 24 cases with high grade serous carcinoma, in 12 cases (54%) P53 immunostaining was detected but in non of all low grade serous carcinoma was seen. All 8 low grade serous carcinoma were alive without recurrence of tumor. In 10 and 12 out of 24 cases with high grade serous carcinoma recurrence of tumor and death were seen respectively.
Conclusion: Since the presence of P53 negative expression in all of low-grade serous carcinoma by immunostaining and low-grade serous carcinoma accounts for small pupulation of all ovarian serous carcinoma and also few cases in our study, we did not find significant differences between P53 expression and survival in two low-grade vs high-grade serous carcinoma groups.

Abstract
Background: Ovarian sex cord-stromal tumors (SCST) account for rare ovarian malignancy. These tumors are 5-8% of all ovarian neoplasms. The most common type of sex cord ovarian tumors is granulosa cell tumor (GCT). In this study our purpose was to have a look at some of clinicopathologic aspects and treatment results of these tumors. Methods: In a retrospective study, all documents of patients with SCST was referred to tumor clinics of Ghaem and Omid Hospitals, from 1998 to 2008. The data of patients were collected and analyzed. Results: In 39 (5.9) of the 398 cases, ovarian malignancies was present in SCST. Eight Patients omitted from the study because there were not enough data for them. The commonest pathology was adult granulosa cell tumor in 25 patients (80.6%). Two patients (8.33%) had juvenile granulosa cell tumor, they were 25 and 38 years old. At time of diagnosis, 27 cases (87.1%) were in early stages (stage I). Mean age of patients was 41 years (range 16-76 years) at time of diagnosis of disease. Surgical staging of cancer was performed in 14 patients (46.7%). We did fertility sparing surgery in 12 patients (40%). Two patients were pregnant after surgery. 17 patients (54.80%) did not receive chemotherapy. Three patients (9.7%) received radiotherapy. Overall survival rates were 95% at both 2 years and 5 years. Longer survival had correlation with early stages of disease (P= 0.002). Age, conservative surgery and chemotherapy had no correlations with survival. Conclusion: The prognosis of SCST is almost good. Most of the patients were diagnosed in early stage of disease. In sex cord ovarian tumor, the only factor that have a full effect on survival, is stage of the disease. If the patients desire to preserve fertility, we can do fertility sparing surgery with minimal effect on survival.
