OBJECTIVES To determine the prevalence and predicting factors of ovarian metastasis, and evaluate the histology of other ovarian neoplasms in women with early-stage cervical cancer. METHODS The medical records of women with cervical cancer stage IA-IIA who underwent primary surgical treatment at Siriraj Hospital, Mahidol University from January 2007 to December 2011 were used for the study. Demographic, clinical and histopathologic data of the women who underwent salpingo-oophorectomy were reviewed. RESULTS Of 264 women, the mean age was 52.3 years. The types of hysterectomy procedures were composed of 210 radical hysterectomy, 9 modified radical hysterectomy, 40 simple hysterectomy, and 5 abandoned hysterectomy. The prevalence of ovarian metastasis was 0.76% (2/264). All of ovarian metastatic patients were older than 60 years old, postmenopause, and had macroscopical stage IB1 cervical cancer. Others ovarian tumors were found in 7 patients including 1 synchronous ovarian carcinoma, 1 serous cystadenoma, 1 fibroma, and 4 teratoma. CONCLUSIONS In cases of early-stage cervical carcinoma of the population studied, ovarian preservation could be another option in <60-year-old patients, with non-neuroendocrine cell type, stage IA, and no extracervical or ovarian lesions.

AIM To evaluate the operative, oncologic and obstetric outcomes of the loop electrosurgical excision procedure (LEEP) in cases with cervical neoplasia. MATERIALS AND METHODS A retrospective cohort study was conducted on patients who were suspected of cervical neoplasia and therefore undergoing LEEP at Siriraj Hospital, Mahidol University, Thailand, during 1995-2000. Outcome measures included operative complications in 407 LEEP patients and long-term outcomes in the 248 patients with cervical intraepithelial neoplasia (CIN) who were treated with only LEEP. RESULTS There were 407 patients undergoing LEEP; their mean age was 39.7±10.5 years. The histopathology of LEEP specimens revealed that 89 patients (21.9%) had lesions ≤CIN I, 295 patients (72.5%) had CIN II or III, and 23 patients (5.6%) had invasive lesions. Operative complications were found in 15 patients and included bleeding (n=9), and infection (n=7). After diagnostic LEEP, 133 patients underwent hysterectomy as the definite treatment for cervical neoplasia. Of 248 CIN patients who had LEEP only, seven (2.8%) had suffered recurrence after a median of 16 (range 6-93) months; one had CIN I, one had CIN II, and five had CIN III. All of these recurrent patients achieved remission on surgical treatment with re-LEEP (n=6) or simple hysterectomy (n=1). A significant factor affecting recurrent disease was the LEEP margin involved with the lesion (p=0.05). Kaplan-Meier analysis showed 5-year and 10-year disease-free survival (DFS) estimates of 99.9%. Twelve patients became pregnant a total of 14 times, resulting in 12 term deliveries and two miscarriages - one of which was due to an incompetent cervix. CONCLUSIONS LEEP for patients with cervical neoplasia delivers favorable surgical, oncologic and obstetric outcomes.

BACKGROUND To determine rates of residual disease along with influencing factors in women with stage IA to IB1 cervical carcinoma after conization. MATERIALS AND METHODS A retrospective study was conducted of medical records of 198 stage IA to IB1 cervical carcinoma patients who had undergoing cervical conization followed by primary surgical treatment during 2006-2013. Independent factors correlating with residual carcinoma in subsequent surgical specimens were analyzed by stepwise regression analysis. RESULTS Mean age was 48.9 years. Cone specimens demonstrated free margins in 36 women (18.8%). In case of having disease at margin, high-grade cervical intraepithelial neoplasia (CIN) and carcinoma were evidenced in 58 and 97 women, respectively. Pathology of subsequent specimens revealed residual carcinoma in 78 women (39.4%), high-grade CIN or adenocarcinoma in situ (AIS) in 45 (22.7%), and no residual pathology in 75 (37.9%). Age more than 35 years, postmenopausal status, having symptoms, diseases or invasive lesions at conization margins or disease on endocervical aspect, and higher stage were significantly correlated with residual cancer in surgical treatment specimens. On regression analysis, postmenopause and stage were independent factors associated with residual carcinoma. CONCLUSIONS Patient and tumor characteristics are predictive factors for residual cancer in the studied group of women.

AIM To report long term outcomes of laser conization for high grade cervical intraepithelial neoplasia (CIN) in Thai women. MATERIALS AND METHODS A retrospective cohort study was conducted in patients undergoing laser conization due to abnormal cervical cytology suggesting neoplasia during 1989 to 1994 and having follow-up data until December 2010. Conization was performed under colposcopy using a 0.5-mm CO2 laser beam with power density of 18,000-20,000 watts/cm2, and the surgical base was vaporized using a low power defocused beam. The follow-up protocol included cervical cytology and colposcopy. Long term outcome measures were failure rate (persistence and recurrence), post-conization status of transformation zone, and obstetric outcomes. RESULTS Of 104 patients undergoing conization, 71 had therapeutic conization for high grade CIN and were followed up for a median time of 115 (range 12-260) months. There was one case of persistent and one of recurrent disease comprising a failure rate of 2.8%. The post treatment transformation zone was well visualized in 68.3% of 63 patients with an intact uterus. Sixteen patients achieved 25 pregnancies; none had second trimester miscarriage. The obstetric outcomes were unremarkable. CONCLUSIONS Laser conization under colposcopic visualization for the treatment of high grade CIN in Thai women has a low failure rate of 2.8%. The post-conization transformation zone could not be evaluated completely in approximately 30% of cases; therefore the follow-up protocol should include both cytology and colposcopy. Obstetric outcomes are not adversely affected by this therapeutic procedure.

OBJECTIVES The purposes of this study were to determine the prevalence and predictive value to detect significant neoplasia and invasive lesions, and to evaluate the correlation between clinical and histopathology of women with squamous cell carcinoma (SCCA) on Siriraj liquid-based cervical cytology (Siriraj-LBC). METHODS The computerized database of women who underwent Siriraj-LBC at Siriraj Hospital, Mahidol University from January 2007 to December 2010 were retrieved. The hospital records of women with SCCA cytology were reviewed. RESULTS The prevalence of SCCA cytology was 0.07%. A total of 86 women, mean age was 58.1 years. Sixty-one women (70.9%) were post-menopausal. Overall significant pathology and invasive gynecologic cancer were detected in 84 women (97.7%) and 71 women (82.5%), respectively. The positive predictive values for detection of significant neoplasia and invasive lesion were 97.7% and 82.6%, respectively. The cervical cancer was diagnosed in 69 women and among these 58 women were SCCA. Thirteen women (15.1%) had cervical intraepithelial neoplasia (CIN) 3 and two women (2.3%) had cervicitis. The sensitivity and specificity of colposcopy for cervical cancer detection in SCCA cytology were 83.3% and 75%, respectively. Median follow up period was 17.6 months and 64 patients were alive without cytologic abnormality. CONCLUSIONS The final histopathology of SCCA cytology in our populations demonstrated a wide variety, from cervicitis to invasive cancer and the most common diagnosis was invasive cervical cancer. Colposcopy with biopsy and/or endocervical curettage and loop electrosurgical excision procedure should be undertaken to achieve histologic diagnosis.

Objectives The aim of this study was to evaluate the rate, clinical characteristics, and survival outcomes of an undiagnosed uterine malignancy in patients who underwent surgical treatment for presumed leiomyomas. Methods Medical records of patients who underwent surgical treatment for presumed leiomyomas, from January 2004 to September 2013, were retrospectively reviewed, and the data were followed until September 2016. Demographic data, tumor characteristics, oncologic treatment, and response rate were analyzed by descriptive statistics. Kaplan-Meier method was used for survival analysis. This study includes follow-up data through December 31, 2016. Results A total of 11,258 medical records of presumed leiomyoma patients undergoing hysterectomy during the studied period were reviewed. Pathology of uterine sarcoma was found in 22 patients (0.2%), all of whom were included. Nineteen patients had leiomyosarcoma, and 3 had endometrial stromal sarcoma. Mean age of patients was 48.3 ± 6.9 years. All patients underwent total abdominal hysterectomy, with 20 patients undergoing concurrent bilateral salpingo-oophorectomy. Uterine sarcoma was classified as stage IB in 21 patients and stage IIIC in 1 patient. Fifteen patients were prescribed the following adjuvant treatment: chemotherapy in 13 patients and megestrol acetate in 2 patients. Thirteen patients had recurrent disease, and 3 patients died of their disease. The mean progression-free survival was 50.1 ± 41.3 months, and overall survival was 59.3 ± 43.0 months. Conclusions One in 512 patients who underwent hysterectomy because of presumed uterine leiomyomas had inadvertent uterine sarcomas. Even with adjuvant therapy, treatment outcome was rather poor, with almost 60% recurrence rate and median progression-free survival and overall survival of less than 5 years.

Objectives To determine response rate and survival outcomes of chemotherapeutic treatment in stage IVB, persistent, or recurrent cervical carcinoma patients. Methods Medical records of stage IVB or persistent or recurrent cervical carcinoma patients who received chemotherapy from January 2006 to December 2013 were retrospectively reviewed. Patients with neuroendocrine carcinoma and patients who received only 1 cycle of chemotherapy were excluded. The demographic data, tumor characteristics, chemotherapeutic agents, and response rate were reported. Factors associated with overall response rate from the first-round chemotherapeutic treatment were analyzed using χ2 test. Kaplan-Meier method and Cox proportional hazards model were used for survival analysis. Results Of 286 cervical carcinoma patients, 47 patients had stage IVB and 239 patients had persistent or recurrent disease. One hundred sixty-nine patients (59.1%) had squamous cell carcinoma (SCC). A majority of disease sites (38.8%) had both local and distant metastases. Overall response rate for first-round chemotherapeutic treatment was 37.8%, with 23.1% of patients having a complete response and 14.7% of patients having a partial response. Regarding disease response, 32.2% of patients had stable disease and 30% had disease progression. Median overall survival (OS) and progression-free survival (PFS) for first-round chemotherapeutic treatment were 11.6 (range, 0.7–108.3) months and 5.6 (range, 0.7–102.2) months, respectively. Patients with distant metastasis had a shorter OS duration with an adjusted hazard ratio (HR) of 1.78, 95% confidence interval (CI) of 1.09 to 2.90; P = 0.02. Patients with a body mass index of 25 kg/m2 or more had a longer PFS duration than those with a normal body mass index (adjusted HR, 0.72; 95% CI, 0.55–0.94; P = 0.018). Patients with non-SCC had a longer PFS duration than that of patients with SCC (adjusted HR, 0.77; 95% CI, 0.60–0.99; P = 0.041). Conclusions Response rates, median PFS, and median OS of cervical cancer patients treated by chemotherapy in our center were rather high when compared with those of previous gynecologic oncology group studies.

PURPOSE To determine the rate of lymph node metastasis, oncologic and pregnancy outcomes in apparent early-stage malignant ovarian germ cell tumor (MOGCT). MATERIALS AND METHODS Medical records of apparent early-stage MOGCT patients undergoing primary surgical treatment at Siriraj Hospital, Bangkok, Thailand, between January 2006 and December 2013, were retrospectively reviewed. RESULTS Thirty-eight patients had apparent stage I-II MOGCT. The mean age was 22.1±7.7 years (median, 20.8 years; range, 7.7-35.6 years). The mean tumor size was 17.8±6.5 cm with a median of 20 (range 4-30) cm. Three most common histopathologies were dysgerminoma (12 patients, 31.6%), immature teratoma (12 patients, 31.6%), and endodermal sinus tumor (6 patients, 15.8%). Twenty-seven of 38 patients underwent lymphadenectomy; 13 patients (48.2%) were stage IA and 8 patients (29.6%) were stage IC. The rate of retroperitoneal nodes metastasis was 7.4% (2/27 patients). At 26.1 months of median follow-up time (range 1.9-88.5 months), 9 patients retained fertility functions, with uneventful pregnancies in 3 of these. Only one patient (2.6%) had progression of disease at 4.9 months after surgery. The 5-year survival rate was 97.4%. CONCLUSION As the rate of pelvic or para-aortic node metastasis in MOGCT is considerable, lymphadenectomy should be incorporated in surgical staging procedures.
