Background: To study the incidence of non-endometrioid carcinoma of endometrium and compare the clinical characteristics and treatment outcomes with endometrioid carcinoma patients. Materials and Methods: This study included 236 patients with endometrial carcinoma at Siriraj Hospital whom were diagnosed and treated from 2003 through 2006. The clinical characteristics, pathological features, treatment and clinical outcomes were collected from the medical records. The 5-year survival was calculated according to 2009 FIGO staging. Results: Non-endometrioid carcinoma of endometrium accounted for 10.2% of all endometrial carcinomas (24/236 patients). The 5-year survival rate was significantly lower in the non-endometrioid group compared to the endometrioid group (77.3% vs 96%, p<0.001) and clinical data pointed to greater malignancy. Conclusions: Non-endometrioid carcinoma of endometrium is relative rare but is more aggressive, has more distant metastasis at diagnosis with a worse survival rate than endometrioid carcinoma. Only patients in stage IA with no residual disease on a hysterectomy specimen may not need adjuvant treatment.

Background: Hemoglobin A1c(HgA1c) is a marker of poor gylcemic control and elevation HgA1c is associated with increased risk of many cancers. We aimed to determine the HgA1c levels in endometrial cancer cases and any relationship with stage and grade of disease. Materials and Methods: A retrospective data review was performed between June 2011 and October 2012 at a tertiary referral center in Turkey. The study included 35 surgically staged endometrial cancer patients and 40 healthy controls. Preoperative HgA1c levels drawn within 3 months before surgery were compared. Also the relationships between HgA1c levels and stage, grade and hystologic type of cancer cases were evaluated. Results: The mean HgA1c levels were statistically significantly higher at $6.19{\pm}1.44$ in endometrial cancer cases than the $5.61{\pm}0.58$ in controls (p=0.027). With endometrial cancer cases, the mean HgA1c level was found to be $6.62{\pm}1.40$ for stage I and $6.88{\pm}1.15$ for stages II-IV (p=0.07). The figures were $6.74{\pm}1.65$ for endometrioid and $6.63{\pm}1.41$ for non-endometrioid type tumors (p=0.56). Mean HgA1c levels of $6.72{\pm}1.14$ for grade 1 and $6.62{\pm}1.42$ for grade 2-3 were observed (p=0.57). Conclusions: HgA1c levels in endometrial cancer patients were statistically higher than healthy controls. However, HgA1c did not show any significant correlation with stage, grade and histologic type in endometrial cancer cases.

Background: Endometrial cancer is the most common gynecological malignancy among females worldwide, approximately 320,000 women being diagnosed with the disease each year and 76,000 dying. To date, there is limited knowledge of endometrial cancer in Malaysia. Objectives: To identify the epidemiological profile and prognostic factors of survival. Materials and Methods: A list of endometrial cancer patients in 2000-2011 was obtained from the hospital Record Department. Only cases confirmed by histopathology examination were included. We excluded those with incomplete medical records or referral cases. Simple and multiple Cox regression approaches were used for data analysis. Results: Only 108 cases were included with a mean (SD) age of 62.7 (12.3) years, with 87.0% Malay ethnicity. Grade of cancer was: 29.1% grade 1, 43.7% grade 2 and 27.2% grade 3. The majority of patients had non-endometrioid type (60.2%), with myometrial invasion (82.2%) and lymphovascular invasion (57.3%). The significant prognostic factors were age (HR 1.05; 95% CI: 1.02, 1.08, p=0.002) and having lymphovascular invasion (HR 2.15; 95% CI: 1.08, 4.29; p=0.030). Conclusions: Endometrial cancer patients should be diagnosed earlier to reduce the risk of mortality. The public should be given education on the signs and symptoms of the disease.

Background: Endometrial carcinoma is the most common malignant tumor of the female genital tract and the fourth most common cancer in Iranian women after breast, colorectal and lung cancers. Various genetic alterations appear to be early events in the pathogenesis of endometrial carcinoma and it seems that PTEN is the most commonly mutated gene in the endometrioid subtype. The aim of the present study was to investigate the correlation between mutations in exon 7 of PTEN gene and endometrial carcinoma. Materials and Methods: Seventy-five patients with endometrial carcinoma and 75 females whose underwent hysterectomy for non tumoral indication were selected for evaluation of PTEN mutations in exon 7 by PCR-SSCP and sequencing. Correlations between the frequency and type of mutation and the pathologic findings of the cancer (tumor subtype, stage and grade) were assessed. Results: All of the samples were obtained from Iranian patients. 60 % (45 cases) of the tumors were endometriod and 40% (30 cases) were of serous type. The grade distributions of the 75 cases according to the FIGO staging system were as follows: low grade, 20 cases; high grade 55 cases, low stage, 41 cases; high stage 34 cases. For exon 7 of the PTEN gene, the analysis showed that there were no mutations in our cases. Conclusions: Our findings in the present study suggest that exon 7 of PTEN does not play any significant role in the development of endometrial carcinoma in Iranian cases.

This study evaluated the relationship between pretreatment hemoglobin (Hb) and prognostic factors in Thai patients with endometrial cancer. Medical records of 228 patients who had undergone surgery between January 2005 and December 2007 were retrospectively reviewed. Associations between clinicopathological variables and pretreatment Hb levels were described using Pearson's chi square test or two-tailed Fisher's exact test. Survival analysis was performed with Kaplan-Meier estimates. Univariate and Cox-regression models were used to evaluate the prognostic impact of various factors, including Hb levels, in term of disease-free survival. The median duration of follow-up was 38.2 months. Eighty-nine patients (39%) had a preoperative Hb level of <12 g/dL, these having significantly higher rates of non-endometrioid histology, advanced FIGO stage, lymphovascular space invasion, cervical involvement, adnexal involvement, positive peritoneal cytology, and lymph node involvement than patients with Hb ${\geq}12$ g/dL. The 5-year disease-free and overall survival were significantly lower in patients with pretreatment Hb levels <12 g/dL compared with those with Hb ${\geq}12$ g/dL (79.3% vs. 89.2%, p=0.044 and 87.6% vs. 99.3%, p<0.001, respectively). In the multivariate analysis only histology, myometrial invasion, and lymphovascular invasion proved to be independent prognostic factors, whereas tumor grading, stage, cervical involvement, adnexal involvement, positive peritoneal cytology, lymph node involvement, and low Hb were not. In conclusion, presence of anemia before treatment may reflect poor prognostic factors in patients with endometrial cancer and low pretreatment hemoglobin level may have a prognostic impact on clinical outcome.
