Impact of background music listening on anxiety in cancer patients undergoing initial radiation therapy: a randomized clinical trial.

BACKGROUND: Patients undergoing radiation therapy (RT) often experience anxiety, which may jeopardize the treatment success. The efficacy of music interventions in reducing anxiety remains contentious. This randomized trial aimed to evaluate the impact of music listening on anxiety symptoms in patients undergoing initial RT. METHODS: First-time RT patients were randomly allocated to experimental and control groups. The Brief Symptom Rating Scale (BSRS-5), Distress Thermometer (DT), and Beck Anxiety Inventory (BAI-C) were administered pre- and post-RT. Changes in physiological anxiety symptoms were monitored over 10 consecutive days starting from the first day of RT. The experimental group received music during RT; the control group did not. The generalized linear mixed model was used to estimate the pre-post difference in the BSRS-5, DT, and BAI-C scores between the music intervention and control group. RESULTS: This study included 50 patients each in the experimental and control groups. BSRS-5 and DT scores were significantly reduced in the experimental group post-RT (p = 0.0114 and p = 0.0023, respectively). When music listening was discontinued, these scores rebounded. While the posttest BAI-C score was significantly lower in the experimental group (p < 0.0001), the pre-post difference between the two groups was not significant (p = 0.0619). On cessation of music listening, the BAI-C score also rebounded. CONCLUSIONS: For cancer patients undergoing initial RT, music listening intervention significantly reduced anxiety symptoms measured using the BSRS-5, DT, and BAI-C scores after two weeks. Our results demonstrate the effectiveness of music listening intervention in reducing anxiety symptoms, thereby potentially improving the quality of life of cancer patients undergoing RT.

CSMed® wound dressing for prophylaxis and management of radiation dermatitis in breast and head-neck cancer patients: a single hospital prospective clinical trial.

PURPOSE: CSMed® wound dressing, a dressing with various herb extracts, was tested for its therapeutic effect in radiation dermatitis of breast and head-and-neck cancer patients. METHODS: This study included 20 breast cancer patients and 10 head-and-neck cancer patients. Half of the irradiated area was covered with CSMed® and the other half was under routine treatment. The severity of radiation dermatitis was evaluated with radiation therapy oncology group (RTOG) grade throughout the treatment and the follow-up period. The RTOG grade between the dressed and undressed area were compared to illustrate the therapeutic effect of CSMed® dressing. RESULTS: The results showed that CSMed® dressed area had significant lower RTOG score at 3-7 weeks and final record during the treatment, and 1-3 weeks during follow-up than undressed area. CONCLUSIONS: This indicated that CSMed® can delay the onset, reduce the severity, and enhance healing of radiation dermatitis. CSMed® can be used for prophylaxis and management of radiation dermatitis.

Synergistic Effect of Ginsenoside Rh2 Combines with Ionizing Radiation on CT26/luc Colon Carcinoma Cells and Tumor-Bearing Animal Model.

BACKGROUND: The local tumor control rate of colon cancer by radiotherapy is unsatisfactory due to recurrence and radioresistance. Ginsenoside Rh2 (Rh2), a panoxadiol saponin, possesses various antitumor effects. METHODS: CT26/luc murine colon carcinoma cells and a CT26/luc tumor-bearing animal model were used to investigate the therapeutic efficacy of Rh2 combined with ionizing radiation and the underlying mechanisms. RESULTS: Rh2 caused cell cycle arrest at the G1 phase in CT26/luc cells; however, when combined with ionizing radiation, the cells were arrested at the G2/M phase. Rh2 was found to suppress the activity of NF-κB induced by radiation by inhibiting the MAPK pathway, consequently affecting the expression of effector proteins. In an in vivo study, the combination treatment significantly increased tumor growth delay time and overall survival. Furthermore, the combination treatment significantly reduced NF-κB and NF-κB-related effector proteins, along with PD-1 receptor expression. Additionally, Rh2 administration led to increased levels of interleukin-12, -18, and interferon-γ in the mice's sera. Importantly, biochemical analysis revealed no toxicities associated with Rh2 alone or combined with radiation. CONCLUSIONS: The combination of Rh2 with radiation may have potential as an alternative to improve the therapeutic efficacy of colorectal cancer.

Effectiveness of multimedia courses in improving self-care among patients with breast cancer undergoing radiotherapy.

BACKGROUND: Ninety percent of patients receiving radiation therapy experience side effects. Busy schedules and intensive health education programs may lead to incomplete education content delivery and inaccurate patient self-care implementation. This study investigated whether multimedia health education improves the accuracy of patient self-care implementation compared with paper-based education. METHODS: From March 11, 2020 to February 28, 2021, 110 patients were randomly divided into experimental and control groups, each comprising 55 participants. Paper-based materials were used along with multimedia materials. Radiology self-care awareness questionnaires were administered to both groups before the first treatment and on day 10. The differences in radiology self-care awareness between the two groups was analyzed with inferential statistics, independent t tests, categorical data, and Pearson's chi-squared test. Differences between the two groups were considered significant at a p value of < 0.05. RESULTS: The treatment accuracy rate improved from 10.9 to 79.1% in the control group and from 24.8 to 98.5% in the experimental group, indicating an improvement in both groups. The difference was significant. These results indicate that the intervention could improve the effectiveness of self-care. CONCLUSIONS: Participants who used pretreatment multimedia health education exhibited a higher rate of having a correct understanding of treatment self-care than did the control group. These findings can inform the development of a patient-centered cancer treatment knowledge base for improved quality of care.

Association between ESR1 rs2234693 single nucleotide polymorphism and uterine fibroids in Taiwanese premenopausal and postmenopausal women.

BACKGROUND: Uterine fibroids (UFs) are uterine smooth muscle neoplasms that affect women, especially during the reproductive stage. Both genetic and lifestyle factors affect the onset of the disease. We examined the association between the estrogen receptor 1 (ESR1) rs2234693 variant (whose genotypes are TT, TC, and CC) and UFs in Taiwanese premenopausal and postmenopausal women. METHODS: We linked individual-level data of 3588 participants from the Taiwan Biobank to the National Health Insurance Research Database at the Health and Welfare Data Science Center. The association of the ESR1 rs2234693 variant and other variables with UFs was determined by multiple logistic regression, and the results were presented as odds ratios and 95% confidence intervals (CIs). RESULTS: The 3588 participants comprised 622 cases and 2966 controls. In all the participants, the ESR1 rs2234693 TC and CC genotypes compared to the reference genotype (TT) were associated with a lower risk of UFs. However, the results were significant only for the CC genotype (OR; 95% CI = 0.70; 0.52-0.93). Noteworthy, the association of TC and CC with UFs was dose-dependent (p-trend = 0.012). Based on menopausal status, both TC and CC were significantly and dose-dependently associated with a lower risk of UFs in premenopausal women (OR; 95% CI = 0.76; 0.59-0.98 for TC and 0.64; 0.43-0.95 for CC: p-trend = 0.010). CONCLUSION: The TC and CC genotypes of the ESR1 rs2234693 variant may reduce susceptibility to UFs, especially in premenopausal women.

Interval changes of histogram-derived diffusion indices predict treatment response to induction chemotherapy in head and neck cancer: a feasibility study.

Background: This retrospective study investigated whether the interval change of apparent diffusion coefficient (∆ADC) [baseline and after the first cycle of induction chemotherapy (ICT)] can be used as a valid predictive imaging biomarker of the treatment response to ICT in head and neck cancer (HNC). Methods: A total of 19 consecutive patients with HNC who underwent diffusion-weighted magnetic resonance imaging (DWI) at baseline and after the first cycle of ICT were included. Whole-tumor ADC histogram parameters (mean, median, kurtosis, skewness, entropy, minimal, maximum, 25th percentile, and 75th percentile) were obtained. The correlations of ∆ADC histogram parameters, volume, T-stage, N-stage, and age with the treatment response were examined using the Mann-Whitney U test. The predictive value of histogram parameters was examined using receiver operating characteristic (ROC) curves. Results: Responders showed significantly higher values of ∆ADC25 (0.19±0.23) and ∆ADCmin (1.78±2.98) than non-responders (-0.09±0.15 and -0.73±0.36; P=0.035 and 0.009, respectively). When ∆ADC25 and ∆ADCmin were used for predicting the treatment response, the area under the ROC curve was 0.850/0.933 with a sensitivity of 73.3%/80.0% and specificity of 100%/100% (P=0.036 and 0.009, respectively). Conclusions: ∆ADC25 and ∆ADCmin derived from whole-tumor histogram analysis are valuable imaging biomarkers for the early prediction of the ICT response in HNC.

High vs. low radiotherapy dose in locally advanced esophageal squamous cell carcinoma patients treated with neoadjuvant concurrent chemoradiotherapy: an endemic area population-based study.

BACKGROUND: The optimal radiotherapy dose for locally advanced esophageal squamous cell carcinoma in endemic areas treated with neoadjuvant concurrent chemoradiotherapy is unclear. METHODS: Eligible patients diagnosed between 2010 and 2019 were identified via the Taiwan Cancer Registry. We used propensity score (PS) weighting to balance observable potential confounders. The hazard ratio (HR) of death was compared between high dose (50-50.4 Gy) and low dose (40-41.4 Gy) radiotherapy. We also evaluated other outcomes and performed supplementary analyses via an alternative approach. RESULTS: Our study population consisted of 644 patients. The PS weight-adjusted HR of death was 0.92 (95% confidence interval: 0.7-1.19, p = 0.51). There were no statistically significant differences for other outcomes or supplementary analyses. CONCLUSIONS: In this population-based study from an endemic area, we found no significant difference in overall survival between high vs. low radiotherapy doses.

Impact of Genetic Variants of Long Noncoding RNA Metastasis-Associated Lung Adenocarcinoma Transcript 1 on Uterine Cervical Cancer.

Genetic variants of long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (lncRNA MALAT1) have been reported to be associated with several cancers. Until now, no study reveals the associations between lncRNA MALAT1 polymorphisms and cervical cancer (CC). The objectives of this study were to explore the correlations among MALAT1 polymorphisms and occurrence and clinicopathological parameters of CC, as well as patient 5 years survival in Taiwanese women. The study recruited 116 patients with cervical invasive cancer and 89 patients with cervical precancerous lesions, as well as 268 non-cancer control women. LncRNA MALAT1 polymorphisms rs3200401, rs619586 and rs1194338 were selected and their genotypic frequencies were defined by real-time polymerase chain reaction. Our results revealed that there are no relationships between lncRNA MALAT1 genetic variants and occurrence of CC. The independent factor among lncRNA MALAT1 genetic variants and clinicopathological parameters were positive pelvic lymph node metastasis (p=0.001, HR: 10.94, 95% CI: 2.65-45.23). In conclusions, lncRNA MALAT1 genetic variants are not related to occurrence and clinicopathological characteristics of CC and patient 5 years survival in Taiwanese women. Pelvic lymph node metastasis could independently predict the patient 5 years survival among various MALAT1 polymorphisms and clinicopathological factors in CC.

Risk of uterine leiomyoma based on BET1L rs2280543 single nucleotide polymorphism and vegetarian diet.

BACKGROUND: Bet1 Golgi vesicular membrane trafficking protein-like (BET1L) rs2280543 single nucleotide polymorphism (SNP) and diet have been independently associated with uterine leiomyoma (UL). However, whether the SNP and diet could jointly influence the risk of UL is yet to be assessed. Therefore, we investigated the independent and interactive effects of vegetarian diet and BET1L rs2280543 on uterine fibroids in Taiwanese women. METHODS: We linked participants' electronic data in the Taiwan Biobank (TWB) database to their medical records in the National Health Insurance Research Database (NHIRD). The TWB had genotypic, lifestyle, and biochemical data between 2008 and 2015 and the NHIRD had data on disease diagnoses between 1998 and 2015. In this study, we included 1997 premenopausal women with complete data. RESULTS: Compared  to participants with the BET1L rs2280543 CC genotype (wildtype), those with CT/CC genotype had an odds ratio (OR) of 0.69 and a 95% confidence interval (CI) of 0.51-0.93. Vegetarian diet and UL were not significantly associated: OR = 1.09 and 95% CI = 0.77-1.55. However, the test for interaction between rs2280543 and vegetarian diet was significant (p = 0.046). Compared to individuals with the CC genotype, the risk of UL was lower among vegetarians with the CT/TT genotype: OR (95% CI) = 0.15 (0.05-0.47). CONCLUSION: The BET1L rs2280543 CT/TT genotype was associated with a lower risk of UL especially among vegetarians.

Evaluating environmental radiations of the tomotherapy facility by optimizing full factorial design of the TLD technique.

BACKGROUND: In the last 40 years, the number of deaths due to cancer has been the highest in TaiwanOBJECTIVE: To optimize the readout system of the thermoluminescent dosimeter (TLD)-100H, the radiation rates among the Tomotherapy (TOMO) facility of the Department of Radiology Oncology of Chung Shan Medical University Hospital (CSMUH) were calculated with a 32 full factorial design (FFD). METHODS: A ten-month survey of the facility was employed using the sensitive and accurate TLD method. The TLD system was optimized for maximum temperature, heat rate, and preheat temperature of Harshaw 3500 reader. Eight analyzed groups with different factors were tested. RESULTS: The TOMO facility had significantly different radiation rates. The farther away from the gantry head, environmental radiation rates. The half value layer (HVL) was also determined. These results were compared with published. No significant contributions of environmental gamma radiations were detected except in the treatment room. CONCLUSIONS: Those were far below the occupational doses recommended by ICRP 60.

Investigating surgical smoke in otolaryngology operating rooms.

Surgical smoke is a common chemical hazard produced from the use of electrocautery, laser, or ultrasonic scalpels during surgery. It has been proved harmful to medical personnel. Thus, it is important to monitor surgical smoke concentrations in the operating room. In the past decade, many researches regarding surgical smoke were discussed in different professional healthcare fields, but few showed the correlation between surgical smoke and otolaryngology surgery. In this study, the concentrations of particulate matter and formaldehyde were measured during thirty cases of several types of otolaryngology surgery in a regional research hospital in Taiwan. The concentrations of 0.3 µm and 0.5 µm particulate matter raised rapidly in the main knife range at the beginning of the electrocautery knife used, and then decreased by half after 5-10 min of use. The concentrations of formaldehyde were ranged from 1 to 2 ppm during the surgery, which is higher than the permissible exposure limit. While many medical staffs are working in the operating room and are exposed to the smoke hazard, effective strategies for collecting and eliminating the smoke should be taken in all medical facilities.

Impact of pentraxin 3 genetic variants on uterine cervical cancer clinicopathologic characteristics.

The aims of this study were to investigate the relationships among pentraxin 3 (PTX3) genetic variants and development and clinicopathological characteristics of uterine cervical cancer, and patient survival in Taiwanese women. The study enrolled 125 patients with invasive cancer and 98 patients with precancerous lesions of uterine cervix, and 325 control women. PTX3 genetic variants rs2120243, rs3816527, rs2305619 and rs1840680 were selected and their genotypic distributions were determined by real-time polymerase chain reaction. Our results indicated that patients with genotype CC in PTX3 rs2120243 and genotype GG in rs1840680 had more chance to have adenocarcinoma but not squamous cell carcinoma, as compared to those with CA/AA and those with GA/AA, respectively. No other clinicopatholgical characteristics were associated with PTX3 genetic variants. In addition, PTX3 genetic variants were not associated with 5 years survival of cervical cancer patients. In conclusions, PTX3 genetic variants are not associated with carcinogenesis and clinicopathological variables of uterine cervix and patient survival in Taiwanese women. The only independent predictor for the 5 years survival is pelvic lymph node metastasis.

Optimal radiotherapy dose in cervical esophageal squamous cell carcinoma patients treated with definitive concurrent chemoradiotherapy: A population based study.

BACKGROUND: The optimal radiotherapy dose for locally advanced cervical esophageal squamous cell carcinoma (C-ESqCC) treated with definitive concurrent chemoradiotherapy (dCCRT) is unclear. Here, we aimed to compare the survival of those treated with high dose versus standard dose via a population based approach. METHODS: Eligible C-ESqCC patients diagnosed between 2011 and 2017 were identified via the Taiwan Cancer Registry. We used propensity score (PS) weighting to balance observable potential confounders between groups. The hazard ratio (HR) of death and incidence of esophageal cancer mortality (IECM) were compared between high (60-70 Gy) and standard dose (50-50.4 Gy). We also evaluated the outcome in supplementary analyses via alternative approaches. RESULTS: Our primary analysis consisted of 141 patients in whom covariates were well balanced after PS weighting. The HR of death when high dose was compared with standard dose was 0.65 (95% confidence interval [CI]: 0.4-1.03, p = 0.07). The HR of IECM was 0.74 (p = 0.45). The HR of OS remained similarly insignificant in supplementary analyses. CONCLUSIONS: We observed a trend in favor of high radiotherapy dose versus standard dose for C-ESqCC treated with dCCRT in this population-based nonrandomized study. Further studies are needed to confirm the findings of the study.

Chemotherapy alone versus definitive concurrent chemoradiotherapy for cT4b esophageal squamous cell carcinoma: a population-based study.

BACKGROUND: The role of radiotherapy for cT4bNanyM0 esophageal squamous cell carcinoma (ESqCC) is relatively unclear, with both chemotherapy (C/T) alone and definitive concurrent chemoradiotherapy (dCCRT) being treatment options in the current guidelines. We aimed to compare the survival of dCCRT versus C/T for these patients via a population-based approach. METHODS: Eligible cT4b ESqCC patients diagnosed between 2011 and 2017 were identified via the Taiwan Cancer Registry. We used propensity score (PS) weighting to balance the observable potential confounders between groups. The hazard ratio (HR) of death and incidence of esophageal cancer mortality (IECM) were compared between dCCRT and C/T. We also evaluated OS in subgroups of either low or standard radiotherapy doses. RESULTS: Our primary analysis consisted of 247 patients in whom covariates were well balanced after PS weighing. The HR for death when dCCRT was compared with C/T was 0.36 (95% confidence interval 0.24-0.53, P < 0.001). Similar results were found for IECM. Statistical significance was only observed in the standard RT dose but not in the low dose in subgroup analyses. CONCLUSIONS: In this population-based nonrandomized study of cT4bNanyM0 ESqCC patients from Asia (Taiwan), we found that the use of radiotherapy with chemotherapy was associated with better overall survival than chemotherapy alone. Further studies (especially RCTs) are needed to confirm our findings.

PM2.5 exposure and DLEC1 promoter methylation in Taiwan Biobank participants.

BACKGROUND: Particulate matter (PM) < 2.5 µm (PM2.5) or fine PM is a serious public health concern. It affects DNA methylation and heightens carcinogenesis. Deleted in lung and esophageal cancer 1 (DLEC1) is a tumor suppressor gene. However, aberrant methylation of the gene is associated with several cancers. We evaluated the association between PM2.5 and DLEC1 promoter methylation in Taiwanese adults based on regular outdoor exercise. METHODS: We obtained DNA methylation and exercise data of 496 participants (aged between 30 and 70 years) from the Taiwan Biobank (TWB) database. We also extracted PM2.5 data from the Air Quality Monitoring Database (AQMD) and estimated participants' exposure using residential addresses. RESULTS: DLEC1 methylation and PM2.5 were positively associated: beta coefficient (ß) = 0.114 × 10-3; p value = 0.046. The test for interaction between exercise and PM2.5 on DLEC1 methylation was significant (p value = 0.036). After stratification by exercise habits, PM2.5 and DLEC1 methylation remained significantly associated only among those who exercised regularly (ß = 0.237 × 10-3; p value = 0.007). PM2.5 quartile-stratified analyses revealed an inverse association between regular exercise and DLEC1 methylation at PM2.5 < 27.37 µg/m3 (ß = - 5.280 × 10-3; p value = 0.009). After combining exercise habits and PM2.5 quartiles, one stratum (i.e., regular exercise and PM2.5 < 27.37 µg/m3) was inversely associated with DLEC1 methylation (ß = -5.160 × 10-3, p value = 0.007). CONCLUSIONS: We found significant positive associations between PM2.5 and DLEC1 promoter methylation. Regular exercise at PM2.5 < 27.37 µg/m3 seemingly regulated DLEC1 promoter methylation.

Osteoporosis and Stress Urinary Incontinence in Women: A National Health Insurance Database Study.

We aimed to determine the influence of osteoporosis and stress urinary incontinence in women. We hypothesized that women with osteoporosis had an increased risk of stress urinary incontinence. This retrospective study used data from the Taiwan Longitudinal Health Insurance database from 2005-2009. The study population was screened to identify women (age ≥ 40 years) newly diagnosed with osteoporosis (ICD-9-CM code = 733.0, 733.1). The osteoporosis cohort included 6125, and the non-osteoporosis cohort included 12,250 participants. The newly diagnosed stress urinary incontinence incidence was calculated to determine the influence of osteoporosis and stress urinary incontinence. We used the Cox proportional hazards model to predict the effects of stress urinary incontinence and the Kaplan-Meier analysis to estimate the cumulative incidence of stress urinary incontinence in women. Participants with osteoporosis experienced a 1.79 times higher risk than that of the non-osteoporosis group (95% CI = 1.28-2.51) for stress urinary incontinence, regardless of age. We did not observe a higher risk of stress urinary incontinence in participants with pathological fractures compared to those with simple osteoporosis. Our data emphasized that physicians and nurses should conduct urinary incontinence screening in women with osteoporosis to recommend proper treatment, medical help or to bring the disorder to light.

Effective dose for multiple and repeated radiation examinations in donors and recipients of adult-to-adult living donor liver transplants at a single center.

PURPOSE: To evaluate the effective doses received by donors and recipients, identify effective dose contributions, and make risk assessments. MATERIALS AND METHODS: It was a retrospective study. 100 Donors and 100 recipients were enrolled with an operative day from March 2016 to August 2017. The dose was analyzed for all radiation-related examinations over a period of 2 years, 1 year before and 1 year after the LDLT procedure. The effective doses of plain X-rays, CT, fluoroscopy, and nuclear medicine per patient were simulated by a Monte Carlo software, evaluated by the dose-length product conversion factors, evaluated by the dose-area product conversion factors, and evaluated by the activity conversion factors, respectively. The risks of radiation-induced cancer were assessed on the basis of the ICRP risk model. RESULTS: The median effective doses were 71 (range: 30-186) mSv for donors and 147 (32-423) mSv for recipients. The radiation examinations were mainly performed in the last three months of preoperative period to first month of postoperative period for recipients and donors. The HCC recipients received a higher effective dose, 195 (64-423) mSv, than those with other indications. The median radiation-induced cancer risk was 0.38 % in male and 0.48 % in female donors and was 0.50 % in male and 0.58 % in female recipients. CONCLUSION: Donors and recipients received a large effective dose, mainly from the CT scans. To reduce effective doses should be included in future challenges in some living donor liver transplants centers that often use CT examinations.

Unmet supportive care needs of survival patients with breast cancer in different cancer stages and treatment phases.

OBJECTIVE: This study aimed to examine the differences between patients with breast cancer (BC) at different cancer stages and treatment phases in terms of unmet supportive care needs as well as to predict the critical factors that influence the unmet needs of such patients. MATERIALS AND METHODS: A retrospective study was conducted by collecting data from the case consultation and service records of a cancer center in central Taiwan. Information extracted from the case consultation and service records included patients' age, treatment phase, cancer stage, and unmet need domains. RESULTS AND CONCLUSION: Overall, 1129 BC patients were recruited. In the prediction of critical factors influential to the health information needs of patients with BC, in-treatment patients, and those undergoing a follow-up were found to have significantly lower health information needs than patients newly diagnosed with BC. In-treatment and follow-up patients had significantly lower patient care needs than those newly diagnosed with BC. Stage II, III, and IV BC patients had significantly lower nutritional needs than stage I patients. In-treatment patients and those receiving follow-ups had significantly lower nutritional needs than patients newly diagnosed with BC. Relapse and terminal care patients had significantly higher psychosocial needs than patients newly diagnosed with BC. Thus, unmet needs of patients with cancer differ according to their age, cancer stage, and treatment phase. Appropriate and punctual tailored support provided by medical care personnel to address the unmet needs of patients can reduce the unmet supportive care needs in such patients and improve the quality of medical care services they are provided with. Ultimately, the overall quality of life of patients can be improved.

Investigation of metastasis-associated in colon cancer-1 genetic variants in the development and clinicopathologcial characteristics of uterine cervical cancer in Taiwanese women.

The objectives of this study were to define the associations among single nucleotide polymorphisms (SNPs) of metastasis-associated in colon cancer-1 (MACC1) gene, development and clinicopathological characteristics of uterine cervical cancer, and patient survival in Taiwan. Genotypic frequencies of 5 MACC1 SNPs rs975263, rs3095007, rs4721888, rs3735615 and rs1990172 were identified for 132 patients with invasive cancer, 99 with high-grade cervical intraepithelial neoplasia and 338 normal controls using real-time polymerase chain reaction. It revealed that there were no associations of these MACC1 SNPs with cervical carcinogenesis. In the meantime, cervical cancer patients with genotype GG in MACC1 SNP rs975263 tended to display more risk to have vaginal invasion than those with AA/AG (p=0.042, OR: 8.70, 95% CI: 0.81-433.22). In multivariate analysis, positive pelvic lymph node metastasis could significantly predict worse 5 years survival rate (p=0.001; HR=9.98, 95% CI=2.64-37.77) for cervical cancer patients. In conclusion, pelvic lymph node status rather than MACC1 SNPs was the only independent parameter that could significantly predict 5 years survival rate in Taiwanese women with cervical cancer.
