Abstract
Objectives: The objective of this study was to evaluate the efficacy of lidocaine spray in reducing the pain during colposcopy-directed cervical biopsy (CDB). Methods: From December 2017 to February 2019, 312 women undergoing CDBs were enrolled. The participants were randomized to three groups: group 1 (lidocaine spray), in which lidocaine spray was applied thoroughly to the cervix; group 2 (placebo), in which normal saline was applied thoroughly to the cervix; and group 3 (control), in which no anesthetic agent was applied to the cervix. Each woman completed a 10 cm visual analog scale to classify the subjective pain experience at three time points: baseline, immediately after biopsy, and 10 min after the procedure. The primary outcome of this study was the biopsy pain score. Results: The 312 enrolled women were randomly assigned to the three groups, amounting to 104 women per group. The clinical and pathological characteristics of the participants in all groups were comparable. The baseline, the biopsy, and the post-procedure pain scores were comparable among the three groups. There was a significant increase in the pain score from baseline to biopsy and from baseline to post-procedure in each group. The pain-score changes from baseline to biopsy in the lidocaine spray group significantly decreased when compared with the normal saline group (<0.001), and tended to decrease, though not significantly (p = 0.06), when compared with the control group. No complication with the intervention was observed. Conclusions: The application of lidocaine spray to the cervix has the benefit of reducing the pain associated with CDBs by a small amount. However, the intervention is safe and may be considered in nulliparous and/or overly anxious women undergoing the procedure.

Abstract
INTRODUCTION To date, there is limited data regarding the incidence and risk prediction of cancer-associated thrombosis among South-East Asian patients who do not receive thromboprophylaxis. MATERIALS AND METHODS This was a prospective cohort study conducted at a tertiary medical center from June 2020 to December 2021 in Thailand. We enrolled cancer patients aged ≥ 18 years, with ECOG score ≤ 1, scheduled to receive the first cycle of chemotherapy. We measured incidence of venous thromboembolism (VTE), all-cause mortality and performance of risk prediction scores. RESULTS A total of 457 patients were included with a mean age of 58.18 ± 12.60 years. By the end of 6 months period, VTE had occurred in 30 patients (6.56 %, 95%CI 4.36-9.21). The median time to the first thrombosis was 1.94 months (IQR 0.26-3.19). Cancer associated thrombosis incidence was 14.58 % for Khorana score ≥ 3, 6.67 % for scores 1-2 and 2.13 % for score 0. C-statistics were 0.50 (95%CI 0.41-0.60) for Khorana score cut-off ≥ 2, 0.57 (95%CI 0.49-0.65) for Khorana score ≥ 3, 0.55 (95%CI 0.46-0.65) for PROTECHT score ≥ 3, and 0.57 (95%CI 0.49-0.65) for CONKO score ≥ 3. Classifying cholangiocarcinoma as very-high-risk increased the Khorana score cut-off ≥ 3's C-statistic to 0.62 (95%CI 0.53-0.71). CONCLUSIONS A significant proportion of ambulatory South-East Asian cancer patients without thromboprophylaxis developed VTE. Further prospective studies investigating the benefit of thromboprophylaxis in high-risk patients with active cancer are warranted.

Abstract
OBJECTIVE This study was aimed at evaluating FYN expression among different histologic types of epithelial ovarian cancer (EOC) and its associated prognostics. METHODS The FYN expression levels using quantitative real-time PCR method were evaluated in 98 primary EOC. Receiver operating characteristic curve were used to select an optimal cut-off value for determining the presence or absence of a disease progression. RESULT The median level of FYN expression varied among different EOC types, being the highest in high-grade serous carcinomas and the lowest in clear cell carcinomas (CCC). Using the cutoff FYN value to predict disease progression, the FYN-positive group had a poorer progression-free survival (PFS) compared to the FYN-negative group (p = 0.001). In multivariate Cox regression analysis, FYN expression was an independent predictor for disease progression (Hazard ratio = 2.30; 95% CI: 1.21- 4.38; p = 0.011). In subgroup analysis, FYN expression was significantly associated with lower PFS in early stage CCC patients (p = 0.009). CONCLUSION FYN expression is variable among different types of EOC while impacting on the prognostic values in patients with early stage CCC.

Abstract
BACKGROUND Malignant ovarian germ cell tumors (MOGCT) are rare and frequently occur in women of young and reproductive age and the oncologic and reproductive outcomes after fertility-sparing surgery (FSS) for this disease are still limited.
AIM To evaluate the oncology and reproductive outcomes of MOGCT patients who underwent FSS.
METHODS All MOGCT patients who underwent FSS defined as the operation with a preserved uterus and at least one side of the ovary at our institute between January 2005 and December 2020 were retrospectively reviewed.
RESULTS Sixty-two patients were recruited for this study. The median age was 22 years old and over 77% were nulliparous. The three most common histology findings were immature teratoma (32.2%), dysgerminoma (24.2%), and yolk sac tumor (24.2%). The distribution of stage was as follows; Stage I, 74.8%; stage II, 9.7%; stage III, 11.3%; and stage IV, 4.8%. Forty-three (67.7%) patients received adjuvant chemotherapy. With a median follow-up time of 96.3 mo, the 10-year progression-free survival and overall survival were 82.4% and 91%, respectively. For reproductive outcomes, of 43 patients who received adjuvant chemotherapy, 18 (41.9%) had normal menstruation, and 17 (39.5%) resumed menstruation with a median time of 4 mo. Of about 14 patients who desired to conceive, four were pregnant and delivered good outcomes. Only one case was aborted. Therefore, the successful pregnancy rate was 28.6%
CONCLUSION The oncology and reproductive outcomes of MOGCT treated by FSS are excellent. Many patients show a long survival time with normal menstruation. However, the obstetric outcome is not quite satisfactory.

Abstract
OBJECTIVE To examine the effectiveness of applying the recommended enhanced recovery after surgery (ERAS) protocol compared with our usual care in women with gynecologic malignancy undergoing elective laparotomy. METHODS From June 2020 to May 2021, 93 women with gynecologic cancers (cervix, endometrium, and ovary) undergoing elective laparotomy at our institution were randomly assigned into an intervention group (ERAS protocol, 46 women) or control group (usual care, 47 women). For the intervention group, each woman was brought through the pre-specified ERAS protocol starting from preoperative counseling to postoperative management. For the control group, participants underwent routine standard care. The primary outcomes were length of hospital stay and postoperative pain. RESULTS The intervention group demonstrated shorter hospital stay by 20 h (47.48 h vs 67.17 h, P = 0.02) with lower postoperative pain score at postoperative day 0 (1.58 vs 4.00, P < 0.01) and day 1 (1.00 vs 2.67, P < 0.01) while having decreased opioid consumption (P < 0.01). The intervention group also had faster recovery of gastrointestinal function. Overall, good compliance to most of the ERAS pathway domains was obtained. CONCLUSION The ERAS protocol demonstrates benefits on shortening hospital stay, reducing pain, and bowel function recovery without increasing complications in our population. CLINICAL TRIAL REGISTRATION The present study was registered at clinicaltrials.gov (NCT04201626) on December 3, 2019. Initial participant enrollment began on June 1, 2020.

Abstract
Abstract
Background and aim
The study of prevalence and risk factors of postoperative lower limb deep vein thrombosis (DVT) in Thai gynecologic patients was limited. The present study was conducted to evaluate this issue.
Methods
The patients were age > 15 years old without a history of DVT or pulmonary emboli (PE) scheduled for laparotomy or vaginal gynecologic surgery between May and November 2020 were invited to participate. All of these patients were scheduled for a complete duplex ultrasound to detect lower limb DVT 72 h before and within 14 days after the operation. The patients without DVT were scheduled for an interview by telephone about DVT symptoms 30 days after the operation. The clinical variables were compared using univariate and multivariate analysis to identify the independent factors related to the development of DVT.
Results
One hundred and twelve patients met the inclusion criteria. Of these patients, 44 cases (39.3%) were diagnosed as malignancy and 102 patients underwent a hysterectomy. Post-operative DVTs were detected in six patients (5.4%) and all except one had a malignancy. Thus, the prevalence of DVT in malignancy cases was five in 44 patients (11.4%). The independent risk factors for postoperative DVT were age > 60-year-old and receiving a perioperative blood transfusion. Five of six DVT patients received low molecular-weight heparin for treatment of DVT and none developed PE. The rest of the participants reported no symptom-related DVTs from the interview 30 days after the operation.
Conclusion
The prevalence of postoperative DVT in gynecologic patients was 5%, and the independent risk factors were elderly patients and receiving a perioperative blood transfusion.

Abstract
Background and Objective: To investigate the efficacy of listening to music on pain reduction during colposcopy-directed cervical biopsy (CDB). Materials and Methods: From June 2020 to November 2021, 240 women undergoing CDB were enrolled. The participants were randomized into three groups: Group 1, colposcopic examination while wearing headphones and listening to music; Group 2, colposcopy while wearing headphones but not listening to music; Group 3 (control group), colposcopy while neither listening to music nor wearing headphones. All participating women completed a 10 cm visual analog scale for subjective pain at three time points: baseline, immediately after cervical biopsy, and 15 min after the procedure. The primary endpoint was the biopsy pain score. Result: Of the 240 women, a sample size of 80 was randomly assigned per group. The clinical–pathological and procedure-related characteristics of the participants in all groups were similar. The mean baseline pain score between each group was not significantly different (2.83 in the music group, 2.54 in group 2, and 2.94 in the control group, p = 0.47). There were no significant differences between each group in terms of mean biopsy pain score (4.21 in the music group, 4.24 in group 2, and 4.30 in the control group, p = 0.98). The differences in changes between the baseline pain score and the biopsy pain score were not statistically significant (1.39 in the music group, 1.70 in group 2, and 1.36 in the control group, p = 0.69). In the multiple comparison analysis, the differences in changes between the biopsy pain score and the baseline pain score between each group were also not statistically significant. There were no complications with the intervention observed. Conclusion: This study demonstrated that there was no beneficial effect of listening to music on pain reduction during colposcopy-directed cervical biopsies.

Abstract
Radical hysterectomy is a recommended treatment for early-stage cervical cancer. However, the procedure is associated with significant morbidities resulting from the removal of the parametrium. Parametrial cancer invasion (PMI) is found in a minority of patients but the efficient system used to predict it is lacking. In this study, we develop a novel machine learning (ML)-based predictive model based on a random forest model (called iPMI) for the practical identification of PMI in women. Data of 1112 stage IA-IIA cervical cancer patients who underwent primary surgery were collected and considered as the training dataset, while data from an independent cohort of 116 consecutive patients were used as the independent test dataset. Based on these datasets, iPMI-Econ was then developed by using basic clinicopathological data available prior to surgery, while iPMI-Power was also introduced by adding pelvic node metastasis and uterine corpus invasion to the iPMI-Econ. Both 10-fold cross-validations and independent test results showed that iPMI-Power outperformed other well-known ML classifiers (e.g., logistic regression, decision tree, k-nearest neighbor, multi-layer perceptron, naive Bayes, support vector machine, and extreme gradient boosting). Upon comparison, it was found that iPMI-Power was effective and had a superior performance to other well-known ML classifiers in predicting PMI. It is anticipated that the proposed iPMI may serve as a cost-effective and rapid approach to guide important clinical decision-making.

Abstract
Background: The prognostic factors for survival in squamous cell carcinoma (SCCA) of vulva cancer such as groin node involvement, postmenopausal status, tumor size, margin status, tumor grade, lymph vascular space invasion (LVSI) were reported in the past. However, with limited data from Southeast - Asian population, the present study was conducted to evaluate the clinicopathological prognostic factors for survival outcomes of this disease after treatment with surgery. Methods: All SCCA vulva cancer patients who underwent surgery between January 2006 and December 2017 were reviewed. The clinicopathological factors were analyzed to identify the prognostic factors for the progression-free survival (PFS) and overall survival (OS) using the Kaplan- Meier method and Cox-Proportional Hazard model. Results: One hundred twenty-five patients were recruited. The independent poor prognostic factors for PFS were groin node-positive and pathologic tumor diameter of more than 25 mm. Whereas postmenopausal status and groin node positive were independent poor prognostic factors for OS. Conclusion: Groin node-positive was the only one independent poor prognostic factor for both PFS and OS. In addition, the tumor diameter longer than 25 mm. was independent poor prognostic factors for PFS while postmenopausal status was independent poor prognostic factors for OS. Special adjuvant treatment for patients with these factors should be further investigated.

Abstract
Background and Objective: Borderline ovarian tumor (BOT) is a distinct but heterogeneous group of tumors defined by histopathology as atypical epithelial proliferation without stromal invasion. Women with BOT are usually younger than those with invasive carcinoma. This study aimed to evaluate the survival outcomes and prognostic factors of patients with BOT in a single institute in the northern region of Thailand. Methods: The medical records of patients with BOT who were treated at Chiang Mai University Hospital between January 1, 2008 and December 31, 2019 were reviewed. The survival outcomes were analyzed by the Kaplan-Meier method and prognostic factors were analyzed by univariate and multivariate approaches. Results: 168 patients with BOT were enrolled in the study. The median age was 48.8 years. At the median follow-up time of 25.4 months, 9 patients (5.3%) developed recurrence and 2 (1.1%) experienced progression to invasive carcinoma. The 5-year progression-free survival (PFS) and overall survival were 93.2% and 97.4%, respectively. By univariate analysis, advanced stage (p=0.02), tumor size smaller than 10 cm (p=0.03), conservative surgery (p=0.03), and bilateral tumors (p=0.07) were significantly associated with worse PFS. Hysterectomy was a protective factor for recurrence with the hazard ratio of 0.09 (95% CI, 0.01 – 0.77; p= 0.03). Cell types, pelvic lymphadenectomy, micro-invasion, and non-invasive peritoneal implant did not significantly affect PFS. By multivariate analysis, early stage (p=0.01), tumor size larger than 10 cm (p=0.04), and hysterectomy (p=0.03) were significantly associated with better survival. Conclusion: Patients with BOT had excellent survival outcomes. Tumor size of larger than 10 cm, early-stage disease, and hysterectomy were significant prognostic factors for better survival outcomes. Conservative surgery should be offered to patients who desire to preserve future fertility and long-term follow-up is needed to assure recurrence - free.

Abstract
Objective: To evaluate the prevalence and potential factors related to irreversible chemotherapy-induced amenorrhea (CIA) in premenopausal women with breast cancer. Methods: First diagnosis breast cancer women in Stages I-III who had menstruation within three months before receiving chemotherapy and completed a course of treatment were interviewed about the menstrual cycle after a complete course of chemotherapy and the subsequent menstrual status. Clinical data were retrospectively reviewed. Age at starting chemotherapy was calculated for an optimal cut-off point by using the receiver operating characteristic curve to predict irreversible CIA. The clinicopathological variables were compared using univariate and multivariate analysis to identify the independent factors related to irreversible CIA. Results: One hundred and fifty-four premenopausal breast cancer women who met the inclusion criteria were interviewed. They were treated with chemotherapy between October 1999 and September 2018. The median age at the start of treatment was 43.5 years. One hundred forty-two patients (92.2%) developed CIA and 37 cases subsequently resumed menstruation (RM). Thus, the prevalence of irreversible CIA was 68.2%. The group > 45 years of age, estrogen receptor-positive, progesterone receptor-positive and maintenance treatment with tamoxifen significantly developed irreversible CIA in univariate analysis. However, only the > 45-year-old group was an independent factor for the CIA with an adjusted odds ratio of 23.04. Conclusion: Nearly 70% of premenopausal breast cancer women developed irreversible CIA and the independent factor for this event was being older than 45-years-old when receiving chemotherapy.

Abstract
Background and objective: Ovarian, fallopian tube, or primary peritoneal cancer patients with BRCA gene mutation have enhanced sensitivity to platinum-based regimens and PARP inhibitors. However, the knowledge regarding BRCA mutation in Thai patients is limited. This study aimed at identifying the prevalence and characteristics of somatic and germline BRCA 1 and 2 mutations in Thai patients with these cancers. Materials and Methods: The paraffin blocks of tumors with histology of high grade serous, high grade endometrioid, or clear cell carcinoma obtained between June 2016 and December 2017 were analyzedto evaluate BRCA mutation using next-generation sequencing system. Blood or normal tissue paraffin blocks of positive patients were further tested for germline BRCA mutation. Results: Tissue paraffin blocks of 178 patients were collected but only 139 were analyzed. Positive BRCA mutation was identified in 24 patients (17.3%): BRCA1 in 13 cases, BRCA2 in 10 cases, and BRCA1 and 2 in the rest one. Germline mutation study in blood or normal tissue in 23 positive patients revealed BRCA mutation in 14 cases, BRCA1 in 8 cases and BRCA 2 in 6 cases. Overall, the prevalence of somatic and germline mutation was 6.5% (9 out of 138 patients) and 8.7% (14 out of 138 patients), respectively. The most common histology associated with BRCA mutation was high grade serous cancer (27.3%). No significant difference was found between patients with or without BRCA mutation in terms of stage, outcome, platinum status, and survival outcome. Conclusion: BRCA mutation was demonstrated in less than 10% of Thai ovarian cancer patients. Higher rate of mutation was found in high grade serous cancer.

Abstract
Background: Side effects of chemotherapy usually disturbed the daily life of patients. During chemotherapy, quality of life of patients is affected by the severity of symptoms experienced. Objective: To evaluate the side effects experienced by gynecologic cancer patients receiving chemotherapy.Methods: Gynecologic cancer patients receiving chemotherapy (at least 1 cycle with standard premedication that included antiemetic drugs) between 18 June and 25 September 2019 were invited to this study. Participants were interviewed by our team for personal data and attitudes toward their disease and treatment. In addition, the Edmonton Symptom Assessment System (ESAS-Thai version) tool, and Multinational Association for Supportive Care in Cancer (MASCC) antiemetic tool were used to assess the symptoms during chemotherapy. Results: One hundred sixty-five participants entered this study. The mean age was 53.5. The three most common type of cancer were ovarian (37.6%), cervical (37.6%) and uterine cancer (21.8%). Most common chemotherapy was carboplatin plus paclitaxel (64.8%). Two-thirds of the participants believed they could be cured. The most common severe symptom from the ESAS tool was pain (20.6%), followed by fatigue (18.8%), appetite change (16.4%) and numbness (10.3%). In addition, 10.9% of patients experienced nausea/vomiting in acute phase, while 20.6% experienced it in the delayed phase. Conclusion: Our participants revealed positive attitudes toward cancer and treatment. Some patients experienced nausea and vomiting despite using antiemetic drugs. The most frequent self-reported symptom was pain. Therefore, pain control was necessary to improve their quality of life.

Abstract
Objective: Our goal was to determine the ex-vivo drug resistance assay, as well as the cytokine production, in
response to platinum-based chemotherapy treatment in primary culture cells established from the tumor tissue of ovarian
or fallopian tube carcinoma patients, and to predict the clinical responses to chemotherapy. Methods: Sensitivity to
the platinum-based drug was analyzed in two ovarian cancer cell lines and 19 tumor samples using the primary cell
culture obtained from 19 patients having ovarian or fallopian tube cancer that had undergone surgery from 2014 to 2017.
Results: Our findings in the ovarian cancer cell lines showed that SKOV3 cells displayed 10-fold greater resistance
to cisplatin and 5.8 times more resistance to carboplatin than A2780 cells. SKOV3 cells displayed platinum-induced
IL-6 and IL-8 overproduction whereas wild type A2780 displayed no detectable cytokine production. Regarding the
primary cell culture obtained from patients, ex-vivo drug resistance assay results revealed that although extreme drug
resistance was correlated with late stage ovarian cancer (P= 0.031), it could not independently predict or alter the
outcomes of patients with ovarian or fallopian tube cancer. No relationship was found between basal cytokine secretion
and the clinical parameters. However, carboplatin-induced IL-6 and IL-8 production had a significant association with
the clinical response to chemotherapy (P=0.016 and P=0.038 respectively). Carboplatin-induced IL-8 overproduction
was correlated with FIGO staging III-IV (P=0.026), but no correlation between carboplatin-induced IL-6 and FIGO
staging (P= 0.061) was noted. Conclusion: These results suggest that cytokine production in response to platinum-based
chemotherapy in primary culture cells may be useful as a predictive marker for the therapeutic outcomes among ovarian
or fallopian tube cancer patients.

Abstract
Background: Tumor budding has recently been reported as an independent adverse prognostic factor for
colorectal adenocarcinomas and other types of carcinoma in the digestive tract. This study aimed to evaluate the
prognostic value of tumor budding in patients with early-stage cervical adenocarcinomas and any associations
with other clinical and pathological features. Methods: Histological slides of patients with early-stage (IB-IIA)
usual-type endocervical adenocarcinoma who underwent radical hysterectomy and pelvic lymph node dissection,
without preoperative chemotherapy, between January 2006 and December 2012 were reviewed. Tumor budding
was evaluated in routinely-stained sections and defined as detached single cells or clusters of fewer than 5 cells in a
tumor invasive front and was stratified based on the number of bud counts in 10-high-power fields as low (<15 buds)
and high (≥15 buds). Correlations between tumor bud count and other clinical and pathological variables including
follow-up outcomes were assessed. Results: Of 129 patients, a high tumor bud count was observed in 15 (11.6%),
positively associated with histologic grade 3 (p<0.001), invasive pattern C (Silva System) (p=0.004), lymph node
metastasis (p=0.008), stage IB2-IIA (p=0.016), and tumor size >2 cm (p=0.036). Kaplan-Meyer analysis showed a
significant decrease in both disease-free survival and cancer-specific survival for patients with a high tumor bud count
(p=0.027 and 0.031, respectively). On multivariate analysis, histologic grade 3 was the only independent predictor for
decreased disease-free survival (p=0.004) and cancer-specific survival (p=0.003). Conclusions: A high tumor budding
count based on assessment of routinely-stained sections was found to be associated with decreased disease-free and
cancer-specific survival in patients with early-stage cervical adenocarcinomas. However, it was not found to be an
independent prognostic predictor in this study.

Abstract
Objective: To compare the incidence rate of carboplatin hypersensitivity reactions (HSRs) in gynecologic cancer
patients receiving one-hour or two-hour carboplatin retreatment infusions. Setting: A Prospective Randomized
Controlled Trial. Methods: Recurrent gynecologic cancer patients 25 to 80-years of age who were scheduled to receive
carboplatin retreatment after previously receiving at least six cycles of carboplatin without a history of platinum allergy
were invited to enroll. They were randomized to receive either a one-hour or two-hour carboplatin infusion in each
cycle. The nurses recorded any occurrence of HSR. Patients who developed carboplatin HSR were discontinued from
the study. Results: Forty-five patients were enrolled and randomized to receive either a one-hour carboplatin infusion
arm in 69 cycles or a two-hour infusion arm in 67 cycles. Both groups were well balanced regarding median age, body
mass index, type of cancer, history of drug allergy, median platinum free interval time, median total number of previous
carboplatin cycles, premedication type, regimen and median total dose of carboplatin. Five (3.67%) of the 136 cycles
resulted in carboplatin HSR, all of which were Grade 1. Of these, four cycles developed HSR during the one-hour
infusion and only one cycle with a two-hour infusion (P=0.37). The onset of carboplatin HSR occurred within 30-105
minutes after infusion start. Conclusion: Extending the carboplatin infusion time to two hours from one hour did not
significantly decrease carboplatin HSR.

Abstract
Metastatic gestational trophoblastic neoplasia (GTN) is an uncommon cancer. The principal treatment consists of chemotherapy with or without surgery or radiotherapy. We here retrospectively reviewed the outcomes of metastatic GTN treated at our institute between January, 1999 and December, 2013. Sixty-three patients met the criteria. The median age was 30.0 years and almost 90% were referral cases. Nearly 40% of the studied patients presented with vaginal bleeding while 22.2% were asymptomatic. The most common antecedent pregnancy was hydatidiform mole (57.1%) followed by term pregnancy (20.6%). The median interval time from antecedent pregnancy to the development of GTN was three months and the median pretreatment B-hCG was 58,274 mIU/ ml. Stage III (74.6%) was the most common staging followed by stage IV (20.6%) and stage II (4.8%). The most frequent surgery was hysterectomy (31.7%). Thoracotomy and craniotomy were performed in three and two patients, respectively. The most common first line chemotherapy regimen was methotrexate and folinic acid (36.5%) followed by EMA (etoposide, methotrexate, actinomycin D) (34.9%), EMACO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine) (17.5%) with the remission rate of 66.7%. Nearly one-third of the patients were given a subsequent chemotherapy regimen after failure with the first line therapy and showed a final response rate of 73.0%. However, in stage IV, the response to first line treatment was only 38.5%. In conclusion, the outcomes of metastatic GTN were poor especially with the higher stages.

Abstract
Background: Cervical cancer is a major public health problem worldwide. There have been several studies
indicating that risk is associated with geographic location and that the incidence of cervical cancer has changed over
time. In Thailand, incidence rates have also been found to be different in each region. Methods: Participants were
women living or having lived in upper Northern Thailand and subjected to cervical screening at Maharaj Nakorn
Chiang Mai Hospital between January 2010 and December 2014. Generalized additive models with Loess smooth
curve fitting were applied to estimate the risk of cervical cancer. For the spatial analysis, Google Maps were employed
to find the geographical locations of the participants’ addresses. The Quantum Geographic Information System was
used to make a map of cervical cancer risk. Two univariate smooths: x equal to the residency duration was used in the
temporal analysis of residency duration, and x equal to the calendar year that participants moved to upper Northern
Thailand or birth year for participants already living there, were used in the temporal analysis of the earliest year. The
spatial-temporal analysis was conducted in the same way as the spatial analysis except that the data were split into
overlapping calendar years. Results: In the spatial analysis, the risk of cervical cancer was shown to be highest in
the Eastern sector of upper Northern Thailand (p-value <0.001). In the temporal analysis of residency duration, the
risk was shown to be steadily increasing (p-value =0.008), and in the temporal analysis of the earliest year, the risk
was observed to be steadily decreasing (p-value=0.016). In the spatial-temporal analysis, the risk was stably higher in
Chiang Rai and Nan provinces compared to Chiang Mai province. According to the display movement over time, the
odds of developing cervical cancer declined in all provinces. Conclusions: The risk of cervical cancer has decreased
over time but, in some areas, there is a higher risk than in the major province of Chiang Mai. Therefore, we should
promote cervical cancer screening coverage in all areas, especially where access is difficult and/or to women of lower
socioeconomic status.

Abstract
Background Testing for high-risk human papillomavirus DNA (HPV test) has gained increasing acceptance as an alternative method to cytology in cervical cancer screening. Compared to cytology, HPV test has a higher sensitivity for the detection of histologic high-grade squamous intraepithelial lesion or worse (HSIL+), but this could lead to a large colposcopy burden. Genotyping for HPV16/18 has been recommended in triaging HPV-positive women. This study was aimed to evaluate the screening performance of HPV testing and the role of genotyping triage in Northern Thailand. Methods A population-based cervical screening program was performed in Chiang Mai (Northern Thailand) using cytology (conventional Pap test) and HPV test (Hybrid Capture 2). Women who had abnormal cytology or were HPV-positive were referred for colposcopy. Cervical samples from these women were genotyped using the Linear Array assay. Results Of 5,456 women, 2.0% had abnormal Pap test results and 6.5% tested positive with Hybrid Capture 2. Of 5,433 women eligible for analysis, 355 with any positive test had histologic confirmation and 57 of these had histologic HSIL+. The sensitivity for histologic HSIL+ detection was 64.9% for Pap test and 100% for Hybrid Capture 2, but the ratio of colposcopy per detection of each HSIL+ was more than two-fold higher with Hybrid Capture 2 than Pap test (5.9 versus 2.8). Genotyping results were available in 316 samples. HPV52, HPV16, and HPV58 were the three most common genotypes among women with histologic HSIL+. Performance of genotyping triage using HPV16/18/52/58 was superior to that of HPV16/18, with a higher sensitivity (85.7% versus 28.6%) and negative predictive value (94.2% versus 83.9%). Conclusions In Northern Thailand, HPV testing with genotyping triage shows better screening performance than cervical cytology alone. In this region, the addition of genotyping for HPV52/58 to HPV16/18 is deemed necessary in triaging women with positive HPV test.

Abstract
Egg white intake during chemotherapy is common advice for cancer patients for the prevention of leukopenia. However, the benefit is uncertain. We conducted this prospective study to identify the relationship of egg white intake for gynecologic cancer patients who received carboplatin and paclitaxel and the occurrence of leukopenia. Between January 2014 and January, 2015, 81 patients were interviewed regarding their intake of egg whites before receiving subsequent chemotherapy. The basic data, the details of egg white intake and the grade of leukopenia in the previous cycle were recorded. The mean age was 54.1 years and 80% of the patients had a diagnosis of ovarian or endometrial cancer. The patients were interviewed at cycles 1-3 in 45 cases, 4-6 in 45 cases and 7-9 in two cases. Subsequent dose reduction was found in 6.2% and granulocyte-stimulating growth factors was given at 4.9%. All the patients ate egg whites with variations in the number of eggs per day as follows: less than one (3), one to two (56), three to four (14) and five to six (8). Over 70% were recommended by nurses to eat egg whites and about 63% of patients received other supplemental food. Some 44.1% of the patients who ate less than or equal to two eggs per day and 36.4% who ate more than two eggs per day developed grade 2-4 leukopenia, P = 0.61. In conclusion, the data did not provide evidence in support of the conclusion that a greater egg white intake could significantly reduce the occurrence of leukopenia.

Abstract
BACKGROUND To investigate the characteristics of allelic distribution of IGF2 and H19 gene polymorphisms in molar tissues compared to normal placentas. MATERIALS AND METHODS Forty-nine specimens of molar tissues as well as 100 control normal placental tissues, delivered on the same days, were collected. Polymerase chain reaction (PCR) with restriction fragment length polymorphism (RFLP) on 2% agarose gel electrophoresis was conducted to determine the allelic distribution. The ApaI polymorphism within exon 9 of IGF2 and the RsaI polymorphism within exon 5 of H19 were employed to identify the allelic distribution of the IGF2 and H19 genes, respectively. Then the data for these genes in the molar and normal placenta tissues were compared. RESULTS The allelic distribution of IGF2 genes found in molar tissue were 21 (42.9%) aa (undigested), 10 (20.4%) ab (heterozygous) and 18 (36.7%) bb (digested), while in normal placenta tissue the values were 22 (22%) aa, 51 (51%) ab, and 27 (27%) bb. The allelic distribution of H19 in molar tissues was 8 (16.2%) aa (undigested), 8 (16.3%) ab (heterozygous) and 33 (67.4%) bb (digested) and in normal placental tissue was 16 (16%) aa, 36 (36%) ab and 48 (48%) bb in normal placenta tissue. These results were significantly different with P values of 0.001 and 0.037 for the allelic distribution of IGF2 and H19, respectively. CONCLUSIONS Molar tissues showed significant differences of allelic distribution of IGF2 and H19 from normal placenta tissues.

Abstract
The objective of this study was to determine the prevalence of significant lesions defined as high grade squamous intraepithelial lesions (HSIL), adenocarcinoma in situ (AIS) and invasive carcinoma in women who had HPV-positive and cytology negative co-testing screening results. This retrospective study was conducted in Chiang Mai University Hospital between May, 2013 and August, 2014. Hybrid capture 2 (HC2) was used for HPV testing and conventional Pap smears for cytologic screening. A repeat liquid-based cytology (LBC) was performed in women with such co-testing results followed by colposcopy. Random biopsy was performed in cases of normal colposcopic findings. Further investigations were carried out according to the biopsy or the repeat LBC results. During the study period, 273 women met the criteria and participated in the study. The mean age of these women was 46.4 years with 30% of them reporting more than one partner. The median interval time to colposcopy was 165 days. About 40% showed an abnormality in the repeat cytology. Significant cervical lesions were found in 20 (7.3%) women, including 2 invasive cancers. Of interest was that only 2 of 20 significant lesions were diagnosed by colposcopic examination while the remainder were initially detected by cervical biopsy and abnormal repeat cytology. In conclusion, the prevalence of significant cervical lesions in HPV positive and cytology negative women in Northern Thailand was 7.3%. Further diagnostic work up with repeat cytology follow by colposcopy is recommended. Random biopsy should be performed even when the colposcopic findings are normal.

Abstract
BACKGROUND Minor cervical cytologic abnormalities include atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL). Approximately 10-20% of women with minor cytologic abnormalities have histologic high-grade squamous intraepithelial or worse lesions (HSIL+). In Thailand, women with minor cytologic abnormalities have a relatively high risk of cervical cancer, and referral for colposcopy has been suggested. A triage test is useful in the selection of women at risk for histologic HSIL+ to reduce the colposcopy burden. The aim of this study was to assess the performance of high-risk HPV DNA test in triage of women with minor cytologic abnormalities in northern Thailand. MATERIALS AND METHODS All women with ASC-US/LSIL cytology who were referred to our colposcopy clinic from October 2010 to February 2014 were included. HPV DNA testing was performed using Hybrid Capture 2 (HC2). All patients received colposcopic examination. Accuracy values of HC2 in predicting the presence of histologic HSIL+ were calculated. RESULTS There were 238 women in this study (121 ASC-US and 117 LSIL). The HC2 positivity rate was significantly higher in the LSIL group than in ASC-US group (74.8% versus 41.0%, p<0.001). Histologic HSIL+ was detected in 9 women (7.4%) in the ASC-US group and 16 women (13.7%) in the LSIL group (p=0.141). There was no histologic HSIL+ detected among HC2-negative cases (sensitivity and negative predictive value of 100%). The performance of HC2 triage was highest among women aged >50 years with ASC-US cytology. An increase in the cut-off threshold for positive HC2 resulted in a substantial decrease of sensitivity and negative predictive value. CONCLUSIONS HPV DNA testing with HC2 shows very high sensitivity and negative predictive value in triage of women with minor cervical cytologic abnormalities in northern Thailand. An increase of the cut-off threshold for HC2 triage is not recommended in this region.

Abstract
To assess survival outcomes in a retrospective study, recurrent epithelial ovarian cancer patients were divided into three groups according to the platinum free interval as follows: platinum refractory that included the patients with tumor progression during treatment; platinum resistant and platinum sensitive that included the patients with tumor progression less than or more than six months, respectively. Clinical data for tumor progression in epithelial ovarian cancer patients treated at Chiang Mai University Hospital between January, 2006 and December, 2010 were reviewed. Thirty-nine patients were in the platinum refractory group while 27 were in the platinum resistant group and 75 in the platinum sensitive group. The mean age, the parity, the administration of neoadjuvant chemotherapy and the serous type did not significantly different across groups while the mean total number of chemotherapy regimens, the early stage patients, the patients with complete surgery and the surviving patients were significant more frequent in the platinum sensitive group. Regarding subsequent treatment after tumor recurrence, 87.2% underwent chemotherapy. With the median follow up time at 29 months, the median overall survival rates were 20 months, 14 months and 42 months in platinum refractory, platinum resistant and platinum sensitive groups, respectively (p<0.001). In addition, when the platinum sensitive patients developed the next episode of tumor progression, the median progression free interval time was only three to four months. In conclusion, the outcomes for platinum refractory the and platinum resistant groups was poorer than the platinum sensitive group. However, subsequent progression in the platinum sensitive group was also associated with a poor outcome.

Abstract
Gestational trophoblastic neoplasia (GTN) is the malignant form of gestational trophoblastic disease. In non-metastatic GTN, the outcomes of treatment are impressive with methotrexate (MTX) or actinomycin D. We retrospectively reviewed the outcomes of non-metastatic GTN treated at our center from January, 1999 to December, 2013. One hundred and nine patients were recruited to the study. The median age was 33.1 years and over 90% were referral cases. Abnormal vaginal symptoms developed in 37.6% while 56.4% were asymptomatic. The most common antecedent pregnancy was a complete mole (92.7%) with the median interval time from antecedent pregnancy to GTN development being 2.0 months. The median pretreatment B-hCG was 5,624 mIu/ ml. The most common first line treatment was methotrexate (MTX) and folinic acid (91.7%) followed by weekly MTX (4.6%), etoposide+ MTX+actinomycin D (EMA) (2.8%), and actinomycin D (0.9%), with the median number of cycles at 5.0. The positive response to first line chemotherapy was 73.8%. The patients were given subsequent chemotherapeutic regimens after resistance to the first line therapy and showed a final remission rate of 89.9%.The significant factor that was frequently found in patients who were non-responders to the first line treatment was a hysterectomy procedure. Two patients developed lung metastasis and brain metastasis at one and four years after the first treatment, respectively. In conclusion, the outcomes of non-metastatic GTN were excellent. However, the patients need long term follow up due to the possibility of developing multiple organ metastases.

Abstract
The gynecologic oncology patients surveillance network program was conducted with the collaboration of 5 provincial hospitals located in the north of Thailand (Chiang Rai, Lamphun Nan, Phayao and Phrae). The aim was to identify ways of reducing the burden and the cost to the gynecologic cancer patients who needed to travel to the tertiary care hospital for follow up. The clinical data of each patient was transferred to the provincial hospital by the internet via the website www.gogcmu.or.th. All the general gynecologists who participated in this project attended the training course set up for the program. From January 2011 to February 2014, 854 patients who were willing to have their next follow-up at the network hospitals close to their home were enrolled this project. Almost of them were residents in Chiang Rai province and the most common disease was cervical cancer. After the project had been running for 1 year, 604 of the enrolled patients and 21 health-care personnel who had participated in this project were interviewed to assess its success. Some 85.3% of the patients and 100% of the health-care personnel were satisfied with this project. However, 60 patients had withdrawn, the most common reason being the lack of confidence in the follow up at the local provincial hospital. In conclusion, it is possible to initiate a gynecologic oncology patients' surveillance network program and the initiation could reduce the problems associated with and the cost the patients incurred as they journeyed to the tertiary care hospital.

Abstract
The Reid colposcopic index (RCI) helps physicians for interpret the results of colposcopic examination. To compare the accuracy of RCI in colposcopic evaluation between general and oncologic gynecologists, this prospective trial was conducted by invited women over 20 years of age who were scheduled for a colposcopy at Chiang Mai University Hospital between August, 2008 and May, 2014 to participate. Pregnant patients or those having a history of hysterectomy or conization were excluded. During the colposcopy, all patients were simultaneously evaluated by general and oncologic gynecologists utilizing the RCI. Further management with either a biopsy or LEEP in each patient was dependent on the decision of the attending oncologic gynecologist. The accuracy of the RCI in diagnosing HSIL or more was calculated by the comparison with the final histology. Finally, 135 patients were recruited into this study. The sensitivity, specificity, PPV, NPV, and accuracy of RCI in diagnosing HSIL or more in general gynecologists were 45.2%, 80.7%, 41.1%, 83.2% and 72.6% while in the oncologic gynecologists were 51.6%, 85.6%, 51.6%, 85.6% and 77.8%, respectively. The difference in accuracy between evaluator groups was not significant (p-value=0.28). Of 3 patients with invasive cervical cancer, all were undetected by the general gynecologists using RCI while only 1 invasive cervical cancer was missed via RCI by the oncologic gynecologists. We conclude that RCI could be used by general gynecologists in provincial hospitals with major concerns about missing invasive cervical cancer. A short training period regarding colposcopy might help to resolve this problem.

Abstract
BACKGROUND Northern Thailand is a region with a high cervical cancer incidence. Combined high-risk HPV (hrHPV) DNA testing and cytology (co-testing) has increasingly gained acceptance for cervical cancer screening. However, to our knowledge, data from a population-based screening using co-testing have not been available in this region. This study therefore aimed to evaluate the performance of cytology and hrHPV test in women in northern Thailand. MATERIALS AND METHODS Cervical samples were collected for hybrid capture 2 (HC2) testing and liquid-based cytology from women aged 30 to 60 years who were residents in 3 prefectures of Chiang Mai in northern Thailand between May and September 2011. Women with positive cytology were referred to colposcopy, while women with positive for HC2 only were followed for 2 years. RESULTS Of 2,752 women included in this study, 3.0% were positive in both tests, 4.1% for HC2 only, and 1.3% had positive cytology only. At baseline screening, positive HC2 was observed in 70.6% among cytology-positive women compared with 4.3% among cytology-negative women. The prevalence of positive HC2 or cytology peaked in the age group 35-39 years and was lowest in the age group 55-60 years. High-grade squamous intraepithelial lesion or worse lesions (HSIL+) were histologically detected in 23.5% of women with positive baseline cytology and in 9.8% of women with positive baseline HC2 only on follow-up. All women with histologic HSIL+ had positive baseline HC2. CONCLUSIONS The hrHPV test is superior to cytology in the early detection of high-grade cervical epithelial lesions. In this study, the prevalence of histologic HSIL+ on follow-up of women with positive hrHPV test was rather high, and these women should be kept under careful surveillance. In northern Thailand, hrHPV testing has a potential to be used as a primary screening test for cervical cancer with cytology applied as a triage test.

Abstract
BACKGROUND This study aimed to develop a prognostic model in patients with early-stage cervical squamous cell carcinoma based on clinicopathological features, including invasive margin characteristics. MATERIALS AND METHODS Clinicopathological features and outcomes of 190 patients with FIGO stage IB-IIA cervical squamous cell carcinoma treated by surgery were collected and analyzed for factors associated with tumor recurrence. In addition to well-recognized pathological risk factors, the pathological characteristics of invasive margin (type of invasive pattern and degree of stromal desmoplasia and peritumoral inflammatory reaction) were also included in the analysis. Multiple scoring models were made by matching different clinicopathological variables and/ or different weighting of the score for each variable. The model with the best performance in the prediction of recurrence and decreased survival was selected. RESULTS The model with the best performance was composed of a combined score of invasive pattern, lymphovascular space invasion (LVSI), and degree of inflammatory reaction and stromal desmoplasia (total score =10). Compared to those with score ≤ 8, the patients with score 9-10 had a significantly higher recurrence rate in the overall group (p<0.001) and the subgroup without adjuvant therapy (p<0.001), while the significance was marginal in the subgroup with adjuvant therapy (p=0.069). In addition, the patients with score 9-10 had a higher rate of tumor recurrence at distant sites (p=0.007). The disease-free survival was significantly lower in the patients with score 9-10 than those with score ≤ 8 among the overall patients (p<0.001), in the subgroup without adjuvant therapy (p<0.001), and the subgroup with adjuvant therapy (p=0.047). CONCLUSIONS In this study, a prognostic model based on a combination of pathological characteristics of invasive margin and LVSI proved to be predictive of tumor recurrence and decreased disease-free survival in patients with early-stage cervical squamous cell carcinoma.

Abstract
Malignant ovarian germ cell tumors (MOGCT) are rare neoplasms that most frequently occur in women at a young reproductive age. There have been limited data regarding this disease from Southeast Asian countries. We therefore conducted a retrospective study to analyze the clinical characteristics and the treatment outcomes of MOGCT treated at our institute between January, 2003 and December, 2012. Seventy-six patients were recruited from this period with the mean age of 21.6 years and 11.8% were pre-puberty. The two most common symptoms were pelvic mass and pelvic pain. Two-thirds of the studied patients presented at an early stage. The most common histology was immature teratoma (34.2%) followed by endodermal sinus tumor (28.9%), dysgerminoma (25%), mixed type (10.5%) and choriocarcinoma (1.3%). Over 80% of these patients received fertility sparing surgery and about 70% received adjuvant chemotherapy with the complete response rate at 73.3% and partial response at 11.1%. The most frequent chemotherapy was BEP regimen (bleomycin, etoposide, cisplatin). With the mean follow up time at 56.0 months, 12 patients (15.8%) developed recurrence and only an advanced stage was the independent prognostic factor. The ten year progression free survival (PFS) and overall survival rate of our study were 81.9% and 86.2%, respectively. In conclusion, MOGCT often occurs at a young age. Treatment with fertility sparing operations and adjuvant chemotherapy with a BEP regimen showed a good outcome. An advanced stage is a significant prognostic factor for recurrence.

Abstract
BACKGROUND Clarifying the prognostic impact of histological type is an essential issue that may influence the treatment and follow-up planning of newly diagnosed cervical cancer cases. This study aimed to evaluate the prognostic impact of histological type on survival and mortality in patients with cervical squamous cell carcinoma (SCC), adenocarcinoma (ADC) and small cell neuroendocrine carcinoma (SNEC). MATERIALS AND METHODS All patients with cervical cancer diagnosed and treated at Chiang Mai University Hospital between January 1995 and October 2011 were eligible. We included all patients with SNEC and a random weighted sample of patients with SCC and ADC. We used competing-risks regression analysis to evaluate the association between histological type and cancer-specific survival and mortality. RESULTS Of all 2,108 patients, 1,632 (77.4%) had SCC, 346 (16.4%) had ADC and 130 (6.2%) had SNEC. Overall, five-year cancer-specific survival was 60.0%, 54.7%, and 48.4% in patients with SCC, ADC and SNEC, respectively. After adjusting for other clinical and pathological factors, patients with SNEC and ADC had higher risk of cancer-related death compared with SCC patients (hazard ratio [HR] 2.6; 95% CI, 1.9-3.5 and HR 1.3; 95% CI, 1.1-1.5, respectively). Patients with SNEC were younger and had higher risk of cancer-related death in both early and advanced stages compared with SCC patients (HR 4.9; 95% CI, 2.7-9.1 and HR 2.5; 95% CI, 1.7-3.5, respectively). Those with advanced-stage ADC had a greater risk of cancer-related death (HR 1.4; 95% CI, 1.2-1.7) compared with those with advanced-stage SCC, while no significant difference was observed in patients with early stage lesions. CONCLUSION Histological type is an important prognostic factor among patients with cervical cancer in Thailand. Though patients with SNEC were younger and more often had a diagnosis of early stage compared with ADC and SCC, SNEC was associated with poorest survival. ADC was associated with poorer survival compared with SCC in advanced stages, while no difference was observed at early stages. Further tailored treatment-strategies and follow-up planning among patients with different histological types should be considered.

Abstract
BACKGROUND This study was undertaken to evaluate the surgical outcomes of patients with stage IA2 cervical cancer treated with radical hysterectomy. Data for 58 patients who underwent modified radical hysterectomy or radical hysterectomy with pelvic lymphadenectomy between January 2003 and December 2012 at Chiang Mai University Hospital were retrospectively reviewed. The analysis included clinico-pathological risk factors (nodal metastasis, parametrial involvement), adjuvant treatment, 5-year disease-free survival and 5-year overall survival. All pathologic slides were reviewed by a gynecologic pathologist. Follow-up methods included at least cervical cytology and colposcopy with directed biopsy if indicated. Univariate analysis was performed to identify factors associated with median survival. At the median follow up time of 73 months, the 5-year disease-free survival and the 5-year overall survival were 97.4% and 97.4%, respectively. Two (3.4%) patients had pelvic lymph node metastases. In a univariate analysis, there was no statistically significant association between survival and prognostic factors such as age, histological cell type, lymph-vascular space invasion, vaginal margin status and lymph node status. Surgical and survival outcomes of women with stage IA2 cervical cancer are excellent. No parametrial involvement was detected in our study. Patients with stage IA2 cervical cancer may be treated with simple or less radical hysterectomy with pelvic lymphadenectomy.

Abstract
BACKGROUND To evaluate the pathological characteristics of invasive margins in early-stage cervical squamous cell carcinomas and their association with other clinicopathological features including clinical outcomes. MATERIALS AND METHODS Patients with FIGO stage IB-IIA cervical squamous cell carcinomas who received surgical treatment and had available follow-up information were identified. Their histological slides were reviewed for prognostic variables including tumor size, grade, extent of invasion, lymphovascular invasion, involvement of vaginal margin or parametrium, and lymph node metastasis. The characteristics of invasive margins including invasive pattern (closed, finger-like, or spray-like type), degree of stromal desmoplasia, and degree of peritumoral inflammatory reaction were evaluated along the entire invasive fronts of tumours. Associations between the characteristics of invasive margins and other clinicopathological variables and disease-free survival were assessed. RESULTS A total of 190 patients were included in the study with a median follow-up duration of 73 months. Tumour recurrence was observed in 18 patients (9%). Spray-like invasive pattern was significantly more associated as compared with closed or finger-like invasive pattern (p=0.005), whereas the degree of stromal desmoplasia or peritumoral inflammatory reaction was not. Low degree of peritumoral inflammatory reaction appeared linked with lymph node metastasis (p=0.021). In multivariate analysis, a spray-like invasive pattern was independently associated with marked stromal desmoplasia (p=0.013), whilst marked desmoplasia was also independently associated with low inflammatory reactions (p=0.009). Furthermore, low inflammatory reactions were independently associated with positive margins (p=0.022) and lymphovascular invasion (p=0.034). The patients with spray-like invasive pattern had a significantly lower disease-free survival compared with those with closed or finger-like pattern (p=0.004). CONCLUSIONS There is a complex interaction between cancer tissue at the invasive margin and changes in surrounding stroma. A spray-like invasive pattern has a prognostic value in patients with early-stage cervical squamous cell carcinoma.

Abstract
OBJECTIVE To evaluate disease-free survival (DFS) after radical hysterectomy and pelvic lymphadenectomy (RHPL) among early-stage cervical cancer patients with single-node involvement versus patients with no nodal involvement. METHODS A retrospective review was conducted of the medical records of 843 patients undergoing RHPL at Chiang Mai University Hospital, Thailand, between January 1, 2002, and December 31, 2008. Neoadjuvant chemotherapy was administered when the operative schedule was more than 1 month after diagnosis and adjuvant chemoradiation was administered to high-risk patients. Five subgroups were defined on the basis of pelvic node involvement: group A (0 nodes; n=706), group B (1 node; n=65), group C (2 nodes; n=38), group D (3 nodes; n=13), and group E (≥4 nodes; n=21). RESULTS The 5-year DFS was comparable for groups A and B (94.3% versus 92.1%; P=0.454). In groups C, D, and E, the 5-year DFS was 85.9%, 75.0%, and 61.8%, respectively. The survival outcomes for groups A and B were significantly different from those of the other 3 groups (P<0.001). CONCLUSION Cervical cancer patients with single-node involvement had comparable survival outcomes to those without nodal metastases; however, patients with multiple node involvement had reduced DFS.

Abstract
Single original gemcitabine is commonly used as salvage treatment in platinum-resistant ovarian cancer, fallopian tube cancer and primary peritoneal adenocarcinoma (PPA) with a satisfactory outcome. However, efficacy data fro this regimen are limited. We therefore conducted a retrospective study to evaluate the outcome of patients who received single-agent generic gemcitabine (GEMITA) after development of clinical platinum resistance. The study period was between May 2008 and December 2010. Gemcitabine was administered intravenously in two different schedules: 1,000 mg/m2 on day 1,8, and 15 every 28 days; and on days 1 and 8 every 21 days with the same dosage. Administration was until disease progression was noted. The response rate was evaluated using the Gynecologic Cancer Intergroup (GCIG ) criteria while toxicity was evaluated according to WHO criteria. Sixty-six patients met the inclusion criteria in the study period. Two-thirds of them received gemcitabine as the second and third line regimen. The overall response rate was 12.1%. The median progression free survival and overall survival was 2 and 10 months, respectively. With the total 550 courses of chemotherapy, the patients developed grades 3 and 4 hematologic toxicity as follows: anemia, 1.5%; leukopenia, 13.7%; neutropenia, 27.3%; and thrombocytopenia, 3.0%. In conclusion, single agent generic gemcitabine revealed a modest efficacy in patients with platinum-resistant ovarian cancer, fallopian tube cancer and PPA without serious toxicity.

Abstract
OBJECTIVE To examine the relationship between the number of pelvic nodes removed and 5-year disease-free survival in early-stage cervical cancer patients who underwent radical hysterectomy and pelvic lymphadenectomy (RHPL). METHODS The medical records of 826 cervical cancer patients who underwent RHPL and who had at least 11 pelvic nodes removed at Chiang Mai University Hospital between January 2002 and December 2008 were reviewed. The patients were divided into 4 groups according to the number of nodes removed: 11-20 nodes (n=243); 21-30 nodes (n=344); 31-40 nodes (n=171); and ≥ 41 nodes (n=68). The 5-year disease-free survival of patients in each group was compared. The clinicopathological factors were analyzed using Cox regression to identify independent prognostic factors. RESULT Five-year disease-free survival was not significantly different among the 4 groups. When patients with and without nodal involvement were considered separately, the 5-year disease-free survival in all groups was not significantly different. At multivariate analysis, the number of pelvic nodes removed was not an independent prognostic factor. CONCLUSION The number of pelvic nodes removed was not associated with 5-year disease-free survival or number of positive pelvic nodes.

Abstract
All gynecologic cancer survivors require a surveillance program for the detection of recurrence and complications after the complete treatment. However, this type of surveillance program might be leading to an unseen burden for the patients. To identify this burden, 200 gynecologic cancer survivors who resided outside of Chiang Mai province were interviewed between November 2010 and February 2011. The mean age of the surveyed patients was 52 years old and most of them were diagnosed with cervical cancer. The mean travelling time was 3.6 hours with a range of one to nine hours and the mean waiting time at the hospital was 5.3 hours. Nearly one-third of the patients required overnight accommodation in Chiang Mai. The mean total cost was 643 baht (60-3,000 baht) and the mean hospital cost was 172 baht. About 44% of the surveyed patients wanted follow up at the local provincial hospital near their abode due to their own convenience. However, more than half of the surveyed patients still wanted to follow up at the tertiary care hospital because of their trust in the medical team. In conclusion, the surveillance program revealed a burden to cancer survivors, especially for the patients who lived a long distance away from the tertiary care hospital province.

Abstract
This study was undertaken to compare the survival rates of stage IB 1 versus stage IB 2 cervical cancer patients and to evaluate the prognostic factors after treatment primarily with radical hysterectomy and pelvic lymphadenectomy (RHPL). Patients with stage IB cervical cancer undergoing primary RHPL at Chiang Mai University Hospital between January 2002 and December 2009 were evaluated for survival and recurrence. Clinicopathological variables were analyzed to identify the prognostic factors affecting the survival of the patients. During the study period, RHPL was performed on 570 stage IB 1 and 110 stage IB 2 cervical cancer patients. With a median follow-up of 48 months, the 5-year disease-free survivals were 98.1% and 82.8% respectively (p<0.001). Multivariate analysis identified four significant prognostic factors affecting survival including sub-staging, non-squamous cell carcinoma histology, lymph node metastasis and the presence of lymph-vascular space invasion. In conclusion, with a primary radical hysterectomy, stage IB 1 cervical cancer patients have a significantly better survival rate than those with stage IB 2. Significant prognostic factors for stage IB cervical cancer include tumor histology, nodal status, and the presence of lymph-vascular space invasion.

Abstract
OBJECTIVE Retrospective evaluation of the outcome of stage IVB, recurrent or persistent cervical cancer treated with cisplatin and generic topotecan (CT) in a tertiary care hospital in Thailand. METHODS The medical records of patients treated with CT regimen at Chiang Mai University Hospital between January 2005 and December 2007 were reviewed and analyzed. The treatment protocol consisted of IV topotecan 0.75 mg/m(2) on days 1, 2, and 3; combined with cisplatin 50 mg/m(2) IV on day 1 and repeated every 21 days until progression or unacceptable toxicity for a maximum of 6 cycles. The outcomes were evaluated based on the response rate, progression free survival (PFS), and overall survival (OS) by using the World Health Organization criteria. The adverse effects of the treatments were also determined. RESULTS Twenty-one cervical cancer patients received the CT regimen. The tumor response rate was 28.6%. The median PFS and OS was 4 and 11 months, respectively. With 87 cycles of chemotherapy, the most common grade 3 & 4 hematologic toxicity was neutropenia (57.9%). CONCLUSION Advanced and recurrent cervical cancer patients treated with cisplatin and generic topotecan had a favorable outcome with manageable toxicity.
