The 10-year cardiovascular risk of physicians estimated by the Thai CV risk score and its association with current coronary artery disease: A retrospective study.

Background and Aims: To assess the 10-year cardiovascular disease (CVD) risk among Thai physicians. The risk compared to the general population and their relationship with the current coronary artery disease (CAD) were also examined. Methods: This retrospective study collected data of Thai physicians who underwent cardiovascular assessments between February 14, 2022, and October 31, 2022. The CVD risk was calculated using the Thai CVD risk (TCVR) score, which incorporated variables of age, gender, smoking, diabetes mellitus, blood pressure, and total cholesterol. Additional collected data included family history of CAD, weekly work hours, fiber diet, exercise, body mass index, coronary artery calcium (CAC) score, and presence of CAD. The association between the risk levels with presence of CAD and clinical features including CAC score were analyzed. Results: Of 1225 physicians, the risk for CVD development was categorized as low in 80.0%, moderate in 11.2%, high in 4.9%, and very high in 3.9%. Among these, 33.6% were found to have higher relative risk compared to the general population of the same age and gender. The overall prevalence of CAD was 11.2%. This prevalence was escalated by risk or relative risk groups: 4.9% in low-, 33.8% in moderate-, 35.1% in high-, and 46.8% in very high-risk groups or 7.2% in lower risk, 8.0% the same risk, and 18.4% higher relative risk groups. Conclusions: Approximately, 20% of Thai physicians in the study exhibited a moderate to very high 10-year risk of CVD. Furthermore, 33.6% of the physicians had higher risk than individuals of the same age and gender in the general population. The prevalence of CAD increased with higher CVD risk and higher relative risk.

Clinical Performance of Self-collected Specimen HPV-DNA vs Clinician- collected Specimen HPV-mRNA to Detect High-risk HPV and High-grade Cervical Lesions and Cancer.

OBJECTIVE: Self- collected specimens to detect high-risk (hr) HPV and high-grade cervical lesions (CIN2+) has been introduced aiming to increase cervical cancer screening coverage. The performance of self- collected specimen  compared to clinician collected specimen is one major concern. This study aimed to compare self-sampling HPV-DNA and clinician-sampling HPV-mRNA to detect hr-HPV and high-grade cervical lesions. METHODS: Women with abnormal cervical cytology and/ or positive hr-HPV who attended the colposcopy clinics in 10 tertiary hospitals in Bangkok were enrolled. Self-collected specimens were evaluated for  HPV DNA using Cobas® 4800 HPV test prior to the clinician-collected specimens which were tested for HPV mRNA with APTIMA® HPV Assay. Subsequent colposcopy with biopsy was performed. The detection rates of hr-HPV from both HPV tests and their performance to detect high-grade lesions pathology were compared. RESULTS: Data from 497 women's specimens were analyzed. Both samplings had 86.8% concordance rate in detecting hr-HPV (Kappa 0.670; 95% confidence interval [CI] 0.599-0.746, P value < 0.001). The sensitivity (95% CI) of self-collected specimen HPV DNA and clinician- collected specimen HPV-mRNA to detect high-grade lesions were 91.8% (85.4%-96.0%) and 90.2% (83.6%-94.9%) respectively. The corresponding negative predictive values (95% CI) were 91.9% (85.6%-96.0%) and 91.7% (86.0%-95.7%) respectively. CONCLUSION: HPV DNA testing from self-collected specimen to detect HR-HPV demonstrates high concordance with HPV mRNA testing from clinician-collected specimen. The sensitivity and negative predictive value of both tests to detect high-grade lesions are comparable.

Exercise and associated features with low-level exercise among doctors.

BACKGROUND: Physical activity had been reported among doctors-in-training, with very few focusing on attending doctors. This study aimed to evaluate the physical activity, particularly exercise, of Thai doctors and features associated with low-level exercise. MATERIALS AND METHODS: Thai doctors who participated in the hospital's CSR service, which was conducted between Feb 14, 2022, to Oct 31, 2022, were verbally informed along with an information sheet about this parallel study. The doctors who consented to participate provided their personal data on diets, work hours, illnesses, health surveillance, stress, state of well-being, and exercise. To investigate the association with clinical features, the exercise level was categorized as low-level (≤ 2 days/week) or high-level (≥ 3 days/week). RESULTS: The median age of 1187 doctors was 45.0 years. Slightly over half were female (55.4%) or worked ≤ 40 hours/week (55.3%). The presence of illnesses was found in 55.9%, irregular health surveillance in 29.0%, no/low fiber diet in 19.2%, overweight/obesity in 28.0%, and moderate/severe stress in 25.9%. Among the doctors who provided exercise data, 29.8% had a high-level of exercise and 49.0% had a low-level. Independent features associated with low-level exercise were no/low fiber diet (aOR = 3.01), irregular health surveillance (aOR = 2.41), age ≤ 60 years (aOR = 1.82), female gender (aOR = 1.79), and work > 40 hours/week (aOR =  1.76). CONCLUSIONS: Only 30% of Thai doctors had a high level of exercise. The significant independent factors for low-level exercise were younger age, female, working load, irregular health surveillance, and no/ low fiber diet.

Abstract Background: Physical activity had been reported among doctors-in-training, with very few focusing on attending doctors. This study aimed to evaluate the physical activity, particularly exercise, of Thai doctors and features associated with low-level exercise. Materials and methods: Thai doctors who participated in the hospital's CSR service, which was conducted between Feb 14, 2022, to Oct 31, 2022, were verbally informed along with an information sheet about this parallel study. The doctors who consented to participate provided their personal data on diets, work hours, illnesses, health surveillance, stress, state of well-being, and exercise. To investigate the association with clinical features, the exercise level was categorized as low-level (≤ 2 days/week) or high-level (≥ 3 days/week). Results: The median age of 1187 doctors was 45.0 years. Slightly over half were female (55.4%) or worked ≤ 40 hours/week (55.3%). The presence of illnesses was found in 55.9%, irregular health surveillance in 29.0%, no/low fiber diet in 19.2%, overweight/obesity in 28.0%, and moderate/severe stress in 25.9%. Among the doctors who provided exercise data, 29.8% had a high-level of exercise and 49.0% had a low-level.

Conclusions: Only 30% of Thai doctors had a high level of exercise. The significant independent factors for low-level exercise were younger age, female, working load, irregular health surveillance, and no/ low fiber diet.

Maternal characteristics and pregnancy outcomes among illicit drug-using women in an urban setting.

OBJECTIVE: To identify characteristics and pregnancy outcomes among pregnant illicit drug users living in an urban area, and to describe trends in drug use over an 8-year period. MATERIALS AND METHODS: Data on pregnant women living in the Bangkok Metropolitan Region who delivered at our institution during 2008-2015 were studied. Women with drug use (n = 197) and women without drug use (n = 787) were compared in terms of maternal characteristics and pregnancy outcomes. RESULTS: The pregnant drug user rate markedly rose from 0.46% in 2008 to 1.28% in 2015. All pregnant drug users consumed amphetamine-type stimulants (ATS). The most important factor related to drug use was smoking (adjusted odds ratio [aOR] 41.03, 95% confidence interval [CI] 18.90-89.04). Other significant characteristics were teenage pregnancy (aOR 1.78, 95% CI 1.01-3.18), low level of education (aOR 4.97, 95% CI 1.18-20.90 for secondary school and aOR 5.61, 95% CI 1.28-24.49 for primary school or lower), and inadequate number of antenatal visits (aOR 2.20, 95% CI 1.16-4.17 for 1-3 visits and aOR 14.05, 95% CI 7.54-26.16 for no visit). Women of non-Thai ethnicity were less likely to use drugs (aOR 0.15, 95% CI 0.04-0.54). Pregnant drug users had a significantly higher risk of anemia (aOR 1.73, 95% CI 1.05-2.85), preterm delivery (aOR 2.35, 95% CI 1.29-4.29), low birth weight (aOR 2.26, 95% CI 1.23-4.17) and small for gestational age infants (aOR 3.19, 95% CI 1.39-7.33), but lower risk of cesarean section (aOR 0.43, 95% CI 0.21-0.86) than non-drug users. CONCLUSION: Compared to urban pregnant women without drug use, women who consumed drugs were younger, had lower level of education, poorer self-care and poorer pregnancy outcomes. ATS was the single most commonly used drug.

Prevalence and Associated Factors of Abnormal Cervical Cytology and HighRisk HPV DNA among Bangkok Metropolitan Women.

BACKGROUND: Many strategies are required for cervical cancer reduction e.g. provision of education cautious sexual behavior, HPV vaccination, and early detection of preinvasive cervical lesions and invasive cancer. Basic health data for cervical cytology/ HPV DNA and associated factors are important to make an appropriate policy to fight against cervical cancer. AIMS: To assess the prevalence of abnormal cervical cytology and/or HPV DNA and associated factors, including sexual behavior, among Bangkok Metropolitan women. MATERIALS AND METHODS: Thai women, aged 25to65 years old, had lived in Bangkok for ≥5 years were invited into the study. Liquidbased cervical cytology and HPV DNA tests were performed. Personal data were collected. MAIN OUTCOMES MEASURES: Rates of abnormal cytology and/ or highrisk HPV (HRHPV) and factors associated with abnormal test(s) were studied. RESULTS: Abnormal cytology and positive HRHPV were found in 6.3% (279/4442 women) and 6.7% (295/4428), respectively. The most common abnormal cytology was ASCUS (3.5%) while the most common HRHPV genotype was HPV 16 (1.4%) followed by HPV 52 (1.0%), HPV 58 (0.9%), and HPV 18 and HPV 51 at equal frequency (0.7%). Both tests were abnormal in 1.6% (71/4428 women). Rates of HRHPV detection were directly associated with severity of abnormal cytology: 5.4% among normal cytology and 13.0%, 30.8%, 40.0%, 39.5%, 56.3% and 100.0% among ASCUS, ASCH, AGCNOS, LSIL, HSIL, and SCC, respectively. Some 5% of women who had no HRHPV had abnormal cytology, in which 0.3% had ≥ HSIL. Factors associated with abnormal cytology or HRHPV were: age ≤40 years, education lower than (for cytology) or higher than bachelor for HRHPV), history of sexual intercourse, and sexual partners ≥2. CONCLUSIONS: Rates for abnormal cytology and HRHPV detection were 6.3% and 6.7% HRHPV detection was directly associated with severity of abnormal cytology. Significant associated factors were age ≤40 years, lower education, history of sexual intercourse, and sexual partners ≥2.

Timing of elective cesarean delivery at term and its impact on maternal and neonatal outcomes among Thai and other Southeast Asian pregnant women.

AIM: The impact of timing of elective cesarean delivery (CD) at term on maternal and neonatal outcomes among Thai and other Southeast Asian pregnancies was investigated. The rate of spontaneous labor before the scheduled CD, as well as maternal characteristics predicting spontaneous labor, was also evaluated. METHODS: Data on maternal and neonatal outcomes of 1221 singleton pregnancies scheduled for either an elective repeat CD or an elective primary CD at 37-40 weeks of gestation were studied. The association between maternal characteristics and the risk of spontaneous labor was evaluated by univariate and multivariate analyses. RESULTS: There were no significant differences in severe maternal complications between performing an elective CD at 39 weeks and at the other gestational ages. Severe neonatal complications were significantly decreased when a CD was performed electively from 38 weeks onwards. A total of 503 women (41.2 %) went into spontaneous labor before the scheduled CD. Using 39 weeks as the reference group, scheduling a CD at 37 or 38 weeks decreased the risk of spontaneous labor (6.67-fold and 4.55-fold, respectively) while scheduling a CD at 40 weeks had a 2.54-fold increased risk. A history of previous CD and teenage pregnancy were also predictors of spontaneous labor; adjusted odds ratios were 14.27 and 3.93, respectively. CONCLUSION: The timing of elective CD at term had impacts on pregnancy outcomes among Thai and other Southeast Asian women. Gestational age at scheduled CD, a previous CD and teenage pregnancy were predictors of spontaneous labor.

Interval debulking surgery for advanced epithelial ovarian cancer.

BACKGROUND: Interval debulking surgery (IDS), following induction or neoadjuvant chemotherapy, may have a role in treating advanced epithelial ovarian cancer (stage III to IV) where primary debulking surgery is not an option. OBJECTIVES: To assess the effectiveness and complications of IDS for women with advanced stage epithelial ovarian cancer. SEARCH METHODS: We searched the Cochrane Gynaecological Cancer Group's Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) 2012, Issue 6, MEDLINE and EMBASE for the original review in to June 2012. We updated the searches in June 2009, 2012 and 2015 for the review updates. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing survival of women with advanced epithelial ovarian cancer, who had IDS performed between cycles of chemotherapy after primary surgery with survival of women who had conventional treatment (primary debulking surgery and adjuvant chemotherapy). DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. Searches for additional information from study authors were attempted. We performed meta-analysis of overall and progression-free survival (PFS), using random-effects models. MAIN RESULTS: Three RCTs randomising 853 women, of whom 781 were evaluated, met the inclusion criteria. Meta-analysis of three trials for overall survival (OS) found no statistically significant difference between IDS and chemotherapy alone (hazard ratio (HR) = 0.80, 95% confidence interval (CI) 0.61 to 1.06, I² = 58%). Subgroup analysis for OS in two trials, where the primary surgery was not performed by gynaecologic oncologists or was less extensive, showed a benefit of IDS (HR = 0.68, 95% CI 0.53 to 0.87, I² = 0%). Meta-analysis of two trials for PFS found no statistically significant difference between IDS and chemotherapy alone (HR = 0.88, 95% CI 0.57 to 1.33, I² = 83%). Rates of toxic reactions to chemotherapy were similar in both arms (risk ratio = 1.19, 95% CI 0.53 to 2.66, I² = 0%), but little information was available for other adverse events or quality or life (QoL). AUTHORS' CONCLUSIONS: We found no conclusive evidence to determine whether IDS between cycles of chemotherapy would improve or decrease the survival rates of women with advanced ovarian cancer, compared with conventional treatment of primary surgery followed by adjuvant chemotherapy. IDS appeared to yield benefit only in women whose primary surgery was not performed by gynaecologic oncologists or was less extensive. Data on QoL and adverse events were inconclusive.

Risk score comprising maternal and obstetric factors to identify late preterm infants at risk for neonatal intensive care unit admission.

AIM: The aim of this study was to develop and validate an antepartum risk score based on maternal and obstetric characteristics to predict the requirement for neonatal intensive care unit (NICU) admission among late preterm infants. MATERIAL AND METHODS: A chart review was performed of 455 singleton late preterm deliveries at our institution between July 2010 and December 2011. Logistic regression analysis was used to develop a risk score, which was derived from ß coefficients of the significant variables. A receiver-operator curve was plotted to determine the optimal cut-off score for predicting NICU admission. Validation of the score was tested in another cohort of 450 women who delivered a singleton late preterm infant between January 2012 and June 2013. RESULTS: A total of 98 infants (21.5%) in the development cohort were admitted to the NICU. The significant factors for NICU admission included: premature rupture of membranes, antepartum hemorrhage, medical disorders during pregnancy, prenatal estimation of fetal weight, gestational age at delivery, and mode of delivery. These six variables were integrated into a risk-scoring model, which ranged from -2 to 9 points. A cut-off score of ≥1 produced the maximum area under the receiver-operator curve of 0.764. At this cut-off point, the sensitivity was 79.6% and specificity was 73.1%. When the risk score was tested in the validation cohort, similar results were demonstrated. CONCLUSION: An antepartum risk score was developed to predict the requirement for NICU admission among late preterm infants and was validated in an independent cohort.

Adjuvant chemotherapy after concurrent chemoradiation for locally advanced cervical cancer.

BACKGROUND: Current standard treatment for patients with cervical cancer who have locally advanced stage disease (International Federation of Gynecology and Obstetrics (FIGO) stage IIB to IVA) is concurrent chemoradiation therapy (CCRT). However, less than two-thirds of patients in this group survive for longer than five years post treatment. Adjuvant chemotherapy (ACT) can be given in an attempt to improve survival by eradicating residual disease in the pelvis and treating occult disease outside the pelvic radiation field. However, inconsistency in trial design, inclusion criteria for participants, interventions and survival benefit has been noted among trials of ACT after CCRT for locally advanced cervical cancer (LACC). OBJECTIVES: To evaluate the effect of adjuvant chemotherapy (ACT) after concurrent chemoradiation (CCRT) on survival of women with locally advanced cervical cancer compared with CCRT alone. SEARCH METHODS: We searched the Cochrane Gynaecological Review Group Trial Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and conference proceedings to March 2014. We handsearched citation lists of relevant studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing CCRT alone versus CCRT plus ACT were included. Patients were diagnosed with cervical cancer FIGO stage IIB to IVA with a histopathology of squamous cell carcinoma, adenosquamous cell carcinoma, adenocarcinoma or undifferentiated carcinoma. DATA COLLECTION AND ANALYSIS: Two review authors (ST, KK) selected relevant trials, extracted data, assessed risk of bias independently, compared results and resolved disagreements by discussion. MAIN RESULTS: We identified two RCTs involving 978 women with cervical cancer stage IIB to IVA. As the trials were significantly different clinically, we did not perform meta-analyses. One industry-funded trial involving 515 women compared CCRT (cisplatin) versus CCRT (cisplatin and gemcitabine) plus ACT (two additional cycles). This trial reported significant improvement in progression-free survival (PFS) and overall survival (OS) in women who were given CCRT plus ACT compared with those treated with CCRT alone: Three-year PFS was 74.4% versus 65.0% (hazard ratio (HR) 0.68, 95% confidence interval (CI) 0.49 to 0.95, P value 0.027), and three-year OS was 80% versus 69% (HR 0.68, 95% CI 0.49 to 0.95, P value 0.022). However, as the CCRT chemotherapy differed between the two arms, we considered the findings to be at high risk of bias.The second trial was a four-arm study from which we extracted data on 463 women in two study arms receiving CCRT (intravenous mitomycin C and oral 5-fluorouracil (5-FU)) or CCRT plus ACT (oral 5-FU for three cycles). The HR for OS in women who received ACT after CCRT compared with the HR for OS in those who were given CCRT alone was 1.309 (95% CI 0.795 to 2.157), and the HR for disease-free survival (DFS) was 1.125 (95% CI 0.799 to 1.586).Haematological adverse events were more common in the ACT arms of both trials. Quality of life (QoL) was not reported in either trial. AUTHORS' CONCLUSIONS: With limited data from only two trials, we found insufficient evidence to support the use of ACT after CCRT. Future large trials are required to demonstrate efficacy, toxicities and QoL.

Cost-utility analysis of treatments for stage IB cervical cancer.

OBJECTIVE: To analyze the cost-utility of two common clinical practices for stage IB cervical cancer patients from provider and societal viewpoints. METHODS: A DECISION TREE MODEL WAS CONDUCTED TO EXAMINE VALUE FOR EXPENDITURE BETWEEN THE FOLLOWING: (1) radical hysterectomy with pelvic lymph node dissection (RHPLND) with or without postoperative adjuvant therapy according to the risk of recurrence and (2) concurrent chemoradiotherapy (CCRT). The relevant studies were identified to extract the probability data, and meta-analysis was performed. Direct medical costs were estimated from hospital database and medical records review. Direct non-medical costs and utility parameters were obtained through interviews with patients to estimate quality-adjusted life years (QALYs) outcome. The time horizon was according to the life expectancy of Thai women. RESULTS: From provider viewpoint, RHPLND and CCRT resulted in approximate costs of US $5,281 and US $5,218, respectively. The corresponding costs from societal viewpoint were US $6,533 and US $6,335, respectively. QALYs were 16.40 years for RHPLND and 15.94 years for CCRT. The estimated incremental cost effectiveness ratio of RHPLND in comparison to CCRT from provider and societal viewpoints were US $100/QALY and US $430/QALY, respectively. RHPLND had more cost-effectiveness than CCRT if patients did not need adjuvant therapy. The most effective parameter in model was a direct medical cost of CCRT. At the current ceiling ratio in Thailand, RHPLND provides better value for money than CCRT, with a probability of 75%. CONCLUSION: RHPLND is an efficient treatment for stage IB cervical cancer. This advantage is only for patients who require no adjuvant treatment.

The rate and mortality of postoperative venous thromboembolism of moderate risk surgery in Asian patients without thrombo-prophylaxis: systematic review with meta-analysis.

BACKGROUND: The general gynecologic and neurologic surgeries are regard as carrying moderate risk for postoperative venous thromboembolism (VTE). This review analyzed the postoperative VTE rate of these surgeries in Asia. METHODS: Inclusion criteria were: prospective study; deep vein thrombosis (DVT) diagnosed by venography, ultrasonography, or radionucleotide scan; and no thromboprophylaxis. The pooled proportion was back calculated from Freeman-Tukey variant transformation, using a random effect model. RESULTS: Medline, EMBASE, Cochrane Library, and KoreaMed were searched. Fourteen studies (total population of 1,625) published from 1974 to 2008 were included. In general surgery, the pooled rate of all-sites proximal, isolated distal DVT was 13.4, 2.1, and 11.8 % (radionucleotide scan). The cancer patients carried a higher all-sites DVT rate (19.7 % radionucleotide scan and 17.4 % ultrasound). Gynecologic and neurologic surgery had 3.1 % (ultrasound) and 3.8 % (radionucleotide scan) all-sites DVT rate. For general, gynecologic, and neurologic patients, the pooled rates of symptomatic DVT were 1.5, 0.2, and 1.0 % respectively. The pooled rate of symptomatic pulmonary embolism (PE) was 0.4 % for general surgery. No patients died from PE (pooled rate 0.2 %); however, a single PE death was reported in the excluded study. CONCLUSIONS: Postoperative symptomatic VTE was relatively low in Asia. Further study is required to stratify VTE risk and the need for thromboprophylaxis in individual patients.

Endometrial carcinoma: clinical characteristic and survival rates by the new compared to the prior FIGO staging systems.

OBJECTIVE: To compare clinical characteristic features and survival rates of endometrial cancer (EMC) patients according to the new 2009 and prior 1988 FIGO staging systems. MATERIAL AND METHOD: Clinico-pathological data of EMC patients who had primary surgical treatment between 1992 and 2008 were collected. The new FIGO staging was compared to the prior assigned staging. Survivals of patients according to prior and new staging were compared RESULTS: Data from 259 patients was reviewed. Mean age was 55.4 +/- 9.9 years. Radiation was the most common adjuvant therapy after surgery, 95/106 patients (89.6%). Progression and recurrences occurred in 34 patients (16 with progression and 18 with recurrence) while 47 died (18.1%). Comparing the prior and current staging, early stage I-II was commonly found in both systems. Stages were the same in 81 patients (31.3%), lower in 177 (68.3%), and higher in one (0.4%). After a median follow-up of 57.5 months, 5-year progression-free, cancer-specific and overall survivals according to the prior and new systems were similar in stage III-IV. Survivals of new stage IA (from 16-prior stage IA, 124-IB, 12-IIA, and 1-IIIA) and stage IB (from 32-IC and 8-IIA) were worse than those of prior stage IA or IB. Survivals of the new stage II patients (11-IIB) were the same as prior stage IIB. CONCLUSION: The "new" FIGO staging system for endometrial cancer patients resulted in lower stage in a large number of patients. Survival trends were worse in the new stage I and remained similar in the other stages.

Treatment outcomes of paclitaxel for refractory or recurrent epithelial ovarian cancer patients in Thailand.

BACKGROUND: To study the response rate, toxicity profiles, and survival of refractory or recurrent epithelial ovarian cancer (EOC) patients treated with paclitaxel. MATERIALS AND METHODS: Patients with refractory or recurrent EOC who were treated with paclitaxel between January 2002 and December 2011 at the Department of Obstetrics and Gynecology, Faculty of Medicine, Vajira Hospital were identified. Clinicopathological features of the patients including detailed data of paclitaxel treatment were collected. RESULTS: During the study period, a total of 44 patients were identified, with a mean age of 52.9±8.2 years. Some 13.6% (six patients) had refractory cancer to first-line chemotherapy while 86.4% (38 patients) had recurrent cancer. Among these, 35 (79.6%) and 9 (20.4%) patients were considered as platinum-sensitive and platinum-resistant, respectively. Three patients (6.8%) received fewer than 2 cycles of paclitaxel due to loss to follow-up, leaving 41 patients evaluable for response. The overall response rate observed in all 41 patients was 41.5% (17 patients; 12 complete and five partial responses): 12.5% or 1/8 patients with refractory or platinum-resistant cancer and 48.5% or 16/33 patients with platinum-sensitive disease. Stable disease was demonstrated in 17.0% (seven patients) while progressive disease was apparent in 41.5% (17 patients). Median time to progress was 4.5 months (range, 0.67- 58.6 months). Median progression-free survival was not reached while median overall survival was 16.3 months (95% confidence interval, 11.0 months -21.6 months). Common toxicities were neutropenia, neuropathy, and alopecia. CONCLUSIONS: Paclitaxel is an active agent for refractory or recurrent EOC. Neutropenia, neuropathy and alopecia are common side effects.

Expression of estrogen receptor, progesterone receptor, and Her-2/ neu in primary and extra-corporeal endometrial cancer.

OBJECTIVE: To compare immunohistochemical (IHC) expression of estrogen receptor (ER), progesterone receptor (PR), and Her-2/neu in the primary tumors of endometrial cancer (EMC) and their extra-corporeal lesions. METHODS: Paraffin-embedded tissues of the primary and extra-corporeal tumors of EMC were retrieved for IHC study. Expression of ER, PR, and Her-2/ neu in the primary tumors and extra-corporeal lesions were compared. RESULTS: From 72 EMC patients with 87 extra-corporeal lesions, positive PR expression was significantly lower in the extra-corporeal lesions than that in the primary sites: 42.5% vs. 63.9%, respectively (p=0.007). No statistically significant differences of ER and Her-2/ neu expressions in the extra-corporeal and the primary sites were found: 42.5% and 55.6% for ER (p=0.102) and 20.7% vs. 13.9% for Her-2/ neu (p=0.262), respectively. The expression of extra-corporeal lesions were concordant to the primary tumor in 65.5% of ER (k=0.319), 71.2% of PR (k=0.445), and 83.9% of Her-2/ neu (k=0.413). From 15 cases wherein IHC from two extra-corporeal sites were studied, 73% had concordant ER expression between the two extra-corporeal lesions (k=0.412) while 93.3% had concordant PR and concordant Her-2/ neu expression (k=0.842 for PR and 0.634 for Her-2/ neu). CONCLUSION: PR expression was significantly higher in the primary tumors than the extra-corporeal sites. Higher ER and lower Her-2/ neu expressions in the primary tumors were also observed but the differences were not significant. The tumors heterogeneity suggests it may be important to study tumor tissues from both primary and extra-corporeal sites when planning treatment, especially by hormonal or targeted therapies.

Platelet to lymphocyte ratio as a prognostic factor for epithelial ovarian cancer.

OBJECTIVE: To determine whether preoperative platelets to lymphocyte ratio (PLR) could predict disease stage, surgical outcome, and survival in patients with epithelial ovarian cancer (EOC). METHODS: Medical records of EOC patients who had surgery between January 2004 and December 2010 were reviewed. Clinicopathological and complete blood count data were collected. The optimal predictive value of PLR to predict advanced stage, suboptimal surgery, and survival was determined and compared with those of thrombocytosis (≥400,000 cells/mm(3)) and neutrophil to lymphocyte ratio (NLR) ≥2.6. RESULTS: A total of 166 EOC patients were included in the study. PLR of 200 yielded better predictive values than those of thrombocytosis and NLR ≥2.6. The area under curve (AUC), sensitivity, specificity, positive and negative predictive values, and accuracy of PLR to predict advanced stage were: 0.66, 59.0%, 72.7%, 65.7%, 66.7%, and 66.3%, respectively. The corresponding values to predict suboptimal surgery were: 0.70, 70.0%, 69.8%, 50.0%, 84.4%, and 69.9%. The patients who had PLR≥200 had significantly shorter progression-free and overall survivals than those with PLR<200. Stage, grade, surgical outcome, thrombocytosis, and PLR were significant prognostic factors for survivals by univariable analyses while only stage remained significant by multivariable analysis. CONCLUSION: PLR had potential clinical value in predicting advanced stage disease or suboptimal surgery. PLR was a better prognostic indicator for survivals of EOC patients compared to thrombocytosis or NLR>2.6.

Comparison of treatment outcomes between squamous cell carcinoma and adenocarcinoma in locally advanced cervical cancer.

OBJECTIVE: To compare the treatment outcomes between squamous cell carcinoma (SCC) and adenocarcinoma (ACA) in locally advanced cervical cancer patients. METHODS: All medical records of stages IIB-IVA of cervical cancer patients who had completed treatment between 1995 and 2008 were reviewed. ACA 1 case was matched for SCC 2 cases with clinical stage, tumor size, treatment modalities (radiation therapy (RT) vs concurrent chemoradiation (CCRT)). Treatment outcomes including response to RT/CCRT, time to complete response (CR), patterns of treatment failure and survival outcomes were analyzed. RESULTS: A total of 423 patients with stages IIB-IVA (141 ACA: 282 SCC) were included. Most of the patients (about 60%) had stage IIB. The overall complete responses (CR) between ACA and SCC were 86.5% and 94.7%, respectively (p=0.004). Median time to clinical CR from RT/CCRT of ACA were 2 months (0-5 months) compared with 1 month (0-4 months) for SCC (p=0.001). Pelvic recurrence and distant failure were found in 2.1% and 14.9% in ACA, and corresponding with 3.9% and 15.6% in SCC. The 5-year overall survival rates of ACA compared to SCC were 59.9% and 61.7% (p=0.191), respectively. When all prognostic factors are adjusted, clinical staging was the only factor that influenced overall survival. CONCLUSION: ACA in locally advanced cervical cancer had poorer response rate from treatment and also used longer time to achieve CR than SCC. However, these effects were not determinants of survival outcomes.

Visual inspection with acetic acid for detection of high grade lesion in atypical squamous cells and low grade squamous intraepithelial lesions from cervical Pap smear.

OBJECTIVE: To evaluate the value of visual inspection with acetic acid (VIA) test to detect high grade lesion in women with atypical squamous cells or low grade squamous intraepithelial lesions cervical cytology. METHODS: Women with atypical squamous cells or low grade squamous intraepithelial lesions who were scheduled to undergo colposcopy at Vajira Hospital and met inclusion criteria were included. All participants underwent VIA test prior to usual steps of colposcopy. The VIA results were interpreted as positive or negative using the criteria by the International Agency for Cancer Research. The standard colposcopic examination and appropriate investigations for cervical pathology were then continued. The diagnostic values of VIA test including sensitivity, specificity, positive predictive value, and negative predictive value were determined using high grade lesion including cervical intraepithelial neoplasia 2-3 and squamous cell carcinoma as a threshold. RESULTS: Total of 106 women was included. The VIA test was positive in 33 women (31.1%) and negative in 73 women (68.9%). Among the women with VIA test positive, 14 had high grade lesion (42.4%) while 19 had no significant lesions. Only 2/73 (2.7%) cases with negative VIA test had high grade lesion (both had cervical intraepithelial neoplasia 2). The sensitivity, specificity, positive predictive value and negative predictive value with 95% confidence interval were 87.5% (81.2 to 93.8%), 78.8% (71.1 to 86.7%), 42.4% (33.0 to 51.8%), and 97.2% (94.2 to 1.0%) respectively. CONCLUSION: VIA as the intermediate test in atypical squamous cells and low grade squamous intraepithelial lesions cytology may reduce the necessity to refer some women for colposcopy.

Treatment outcomes of concurrent weekly carboplatin with radiation therapy in locally advanced cervical cancer patients.

OBJECTIVE: To evaluate treatment outcomes of locally advanced cervical cancer patients who received concurrent weekly carboplatin with radiation therapy. METHODS: Patients with locally advanced cervical cancer who had primary radiation treatment in concurrent with weekly carboplatin (100mg/m(2) or AUC 2) from 1997 to 2008 were identified. Demographic data, chemotherapy cycles, total treatment time, toxicities, and treatment outcomes were recorded. RESULTS: One hundred and forty-eight patients with stage IIB (50.7%), IIIB (48.0%) and IVA (1.3%) cervical cancer patients were included in the study. Median total treatment time was 53.5 days (range, 45-100 days). Carboplatin was given for a median number of 6 cycles (range, 3-6 cycles). Complete response was achieved in 142 patients (95.9%) while six (4.1%) had persistent diseases. Among the 142 responders, 36 experienced recurrences: pelvic recurrences in seven (4.7%), distant failure in 25 (16.9%), and both pelvic and distant in four (2.7%). The 2-year and 5-year progression-free survival rates were 75.1% and 63.0%, respectively with the corresponding 2-year and 5-year overall survival rates of 81.9% and 63.5%. No grade 3 or 4 hematologic and non-hematologic toxicities were observed during treatment in any patients. Late grade 3-4 gastrointestinal or genitourinary toxicities were 10.1% and 0.7%, respectively. CONCLUSION: Concurrent weekly carboplatin with radiation therapy yields high response rate with modest progression-free and overall survivals in locally advanced cervical cancer. The regimen is feasible with minimal toxicities.
