The comparison of 1988 and 2009 FIGO staging system for uterine sarcoma in King Chulalongkorn Memorial Hospital during 1999-2008

Abstract

Backgrounds: Uterine sarcoma was staged previously according to the 1988 FIGO staging system for endometrial adenocarcinoma. However, in 2009 a new staging system for uterine sarcoma has been developed.

Objectives: The purpose of this study was to compare the survival between traditional and new FIGO staging system.

Materials and methods: The medical records of uterine sarcoma patients who received primary treatment at King Chulalongkorn Memorial Hospital, Thailand between 1999 and 2008 were reviewed. The survival curves were generated by Kaplan-Meier method. A comparison of survival between groups was assessed by the log-rank test.

Results: Thirty-three patients were included. The incidence of uterine sarcoma was 0.8% and 4.4% of all gynecologic cancers and uterine cancer, respectively. A comparison between these two staging systems showed that four patients (12.1%) were down-staged and none was up-staged. The 5-year disease-free survival (DFS) and overall survival (OS) were 40.4% and 56.0%, respectively. Age, parity, histology, tumor size, lymph node dissection, and adjuvant treatments were not significant prognostic factors. Patients with early stage had significantly longer survival than those with advanced stage. Mean DFS in early stage according to 1988 and 2009 FIGO staging system were 80 and 77 months, respectively. Mean OS were 97 months and 91 months, respectively. Mean DFS in advanced stage were 34 months and 15 months, respectively. Median OS were 12 months and 10 months, respectively. There was no difference in survival between these two staging systems.

Conclusions: Stage is the only independent prognostic factor. There was no difference in survival between these two staging systems.

Proportion of vulvar premalignant and malignant lesions in overall vulvar specimens in Thailand

Abstract

Background

Vulvar lesion is one of the common gynecologic problems.

Objective

To assess the proportion of vulvar premalignant and malignant lesions in overall vulvar specimens and to evaluate the clinicopathologic features of each vulvar lesion in King Chulalongkorn Memorial Hospital (KCMH).

Methods

Pathological microscopic slides and medical records of the patients who underwent vulvar-related operations between January 1, 2002 and December 31, 2015 were reviewed. Patients’ clinical characteristics and pathologic features were evaluated and analyzed.

Results

A total number of 700 patients were included. The proportion of malignant and premalignant lesions in overall vulvar specimens were 16.3% and 8.4%, respectively. Squamous cell carcinoma was the most common malignant vulvar lesion (48.2%), whereas vulvar intraepithelial neoplasia 1 (VIN1) (33.9%) was the most common lesion in the premalignant group. On multivariate analysis, four clinical factors were significantly associated with malignancy risk: increased parity (odds ratio [OR] 1.19, P = 0.010), large tumor size (OR 2.00, P < 0.001), lesion at clitoris (OR 16.67, P = 0.002), and erythematous lesion (OR 2.41, P = 0.026).

Conclusions

The proportion of malignant and premalignant lesions in overall vulvar specimens was 24.7% in KCMH. Increased parity, large tumor size, clitoris-located lesion, and erythematous lesion were associated with increasing malignancy risk.
