Factors involved in the delay of treatment initiation for cervical cancer patients
Medicine, 2016
Cervical cancer ranks as the fourth leading cause of cancer death in women worldwide. In Taiwan, although the universal health insurance system has achieved 99.9% coverage and ensured easy access to medical care, some cervical cancer patients continue to delay initiation of definitive treatment after diagnosis. This study focused on cervical cancer patients who delayed treatment for at least 4 months, and examined the characteristics, related factors, and survival in these patients.

Objective: The objective of this study was to determine the five-year survival among patients with cervical cancer treated in Hospital Universiti Sains Malaysia. Methods: One hundred and twenty cervical cancer patients diagnosed between 1 st July 1995 and 30 th June 2007 were identified. Data were obtained from medical records. The survival probability was determined using the Kaplan-Meier method and the log-rank test was applied to compare the survival distribution between groups. Results: The overall five-year survival was 39.7% [95%CI (Confidence Interval): 30.7, 51.3] with a median survival time of 40.8 (95%CI: 34.0, 62.0) months. The log-rank test showed that there were survival differences between the groups for the following variables: stage at diagnosis (p=0.005); and primary treatment (p=0.0242). Patients who were diagnosed at the latest stage (III-IV) were found to have the lowest survival, 18.4% (95%CI: 6.75, 50.1), compared to stage I and II where the five-year survival was 54.7% (95%CI: 38.7, 77.2) and 40.8% (95%CI: 27.7, 60.3), respectively. The five-year survival was higher in patients who received surgery [52.6% (95%CI: 37.5, 73.6)] as a primary treatment compared to the non-surgical group [33.3% (95%CI: 22.9, 48.4)]. Conclusion: The five-year survival of cervical cancer patients in this study was low. The survival of those diagnosed at an advanced stage was low compared to early stages. In addition, those who underwent surgery had higher survival than those who had no surgery for primary treatment.

PURPOSETo estimate treatment delays and associated factors among women diagnosed with cervical cancer who were treated at the main cancer center in Rio de Janeiro, Brazil.MATERIALS AND METHODSA retrospective cohort study was performed comprising 865 women newly diagnosed with cervical cancer between 2012 and 2014. Times from diagnosis to treatment initiation (less than or equal to 60 days) and from diagnosis to treatment ending (less than or equal to 120 days) were analyzed according to the Brazilian law for the treatment of patients with cancer. Associations between treatment delays and sociodemographic, economic, lifestyle, clinical, and treatment variables were estimated using logistic regression models, with 95% CIs.RESULTSThe average age was 48 (± 13.7) years, and the median age was 47 years; 36.2% of patients had stage IIIB to IVA disease. The median time from diagnosis to treatment initiation was 114 days, which was statistically higher among women with stage IIB to IVA (105....
Survival Rate of Cervical Cancer in National Referral Hospital in 2012 - 2014
Acta medica Indonesiana, 2019
BACKGROUND cervical cancer is the third leading cause of female deaths worldwide, and it is the leading cause of female deaths in developing countries. A routine survival evaluation is required to imply the result of the treatment. The aim of this study was to determine the cervical cancer patient survival rate at the Cipto Mangunkusumo hospital as national referral hospital in Indonesia. METHODS our retrospective cohort study utilized the medical records of cervical cancer patients from 2012 to 2014 using total population sampling method. The data analysis was conducted using the Kaplan-Meier curve, log rank test and Cox regression to determine significant associations between variables. RESULTS there were 1,303 subjects with overall survival rates of cervical cancer up to the fifth year of 76%, 65%, 59%, 43% and 34%, respectively, with a median survival of 1,316 days. There were significant differences of hazard ratio for cancer stage variables (p<0.001), and the Cox regression...

Background Cervical cancer is a growing public health problem globally. Despite the availability of management options, the progression of the disease as a function of waiting time may challenge the effort to attain a desired outcome. There is a conflicting report on the role of waiting time to initiate an appropriate treatment in improving patients’ survival. Objective This review aims to evaluate the association between delayed time to initiate any treatment indication with survival in patients with cervical cancer. Methods An internet-based literature search will be performed using text words, MESH terms and truncated words in databases, namely MEDLINE, Cochrane CENTRAL, EMBASE, Web of Science and Scopus. Grey literature searches in Google Scholar, Networked Digital Library of Theses and Dissertations (NDLTD) and Dissertations and Theses Global will be made. All articles published until 30th of December 2021 on human subjects will be searched without a language restriction. Studi...

Cervical cancer is the third most common cancer among women in Malaysia. The objective of this study was to estimate the effect of explanatory variables on survival time of cervical cancer patients receiving treatment at a hospital in Malaysia. In this retrospective record review study, cervical cancer data obtained from Hospital UniversitiSains Malaysia (HUSM) was analysed. The data comprises of 120 patients who had been diagnosed as cervical cancer between 1(st) July 1995 and 30(th) June 2007, and obtained treatment from the hospital. The outcome variable was survival time (in months) from cervical cancer diagnosis to death. A stratified Weibull model was applied to study the effect of explanatory variable on survival time when there was time-dependent covariate in the model. Stage of disease and metastases were important prognostic variables. However, metastasis had been stratified because this variable did not satisfy the proportional hazard assumption. In without metastasis str...
Prognostic model for survival in patients with early stage cervical cancer
Cancer, 2011
BACKGROUND: In the management of early stage cervical cancer, knowledge about the prognosis is critical. Although many factors have an impact on survival, their relative importance remains controversial. This study aims to develop a prognostic model for survival in early stage cervical cancer patients and to reconsider grounds for adjuvant treatment. METHODS: A multivariate Cox regression model was used to identify the prognostic weight of clinical and histological factors for disease-specific survival (DSS) in 710 consecutive patients who had surgery for early stage cervical cancer (FIGO [International Federation of Gynecology and Obstetrics] stage IA2-IIA). Prognostic scores were derived by converting the regression coefficients for each prognostic marker and used in a score chart. The discriminative capacity was expressed as the area under the curve (AUC) of the receiver operating characteristic. RESULTS: The 5-year DSS was 92%. Tumor diameter, histological type, lymph node metastasis, depth of stromal invasion, lymph vascular space invasion, and parametrial extension were independently associated with DSS and were included in a Cox regression model. This prognostic model, corrected for the 9% overfit shown by internal validation, showed a fair discriminative capacity (AUC, 0.73). The derived score chart predicting 5-year DSS showed a good discriminative capacity (AUC, 0.85). CONCLUSIONS: In patients with early stage cervical cancer, DSS can be predicted with a statistical model. Models, such as that presented here, should be used in clinical trials on the effects of adjuvant treatments in high-risk early cervical cancer patients, both to stratify and to include patients.

Variations in survival for invasive cervical cancer among European women, 1978-89
1999
Objectives: To analyze cervical cancer survival trends in 10 European countries using models that estimate the proportion of cured patients (having the same life expectancy as the general population) and the survival of fatal cases (who die from cervical cancer). Methods: We considered 40,906 cases diagnosed over 12 years (1978±89) collected from cancer registries participating in EUROCARE. Results: From 1978 to 1989, 5-year relative survival in Europe improved (60%®63%). The proportion of cured patients increased slightly but signi®cantly (53%®55%, p = 0.05). For countries with poorer survival at the end of the 1970s the proportion of cured patients increased faster than average, particularly evident in England (49%®56%) and Scotland (44%®53%). By contrast, in Finland, Sweden and Germany with organized screening, 5-year survival and cure rate did not improve, but incidence declined to very low levels. Conclusions: Cervical screening can explain the trends in cervical cancer survival: this identi®es premalignant lesions, reduces incidence and selectively prevents less aggressive cancers. The decreased proportion of the latter means that survival does not improve in countries with low incidence of cervical cancer. The increased proportion of cured patients with time shows that survival improvement was not due simply to earlier diagnosis with no patient advantage.

PURPOSE In Tanzania, cancer of cervix is the most commonly diagnosed cancer and is the leading cause of cancer-related deaths. There are very little data about survival of patients with cervical cancer after treatment in Tanzania. The aims of this study were to determine 5-year overall survival (OS) rate and its predictors among patients with cervical cancer treated at Ocean Road Cancer Institute (ORCI) from January to December 2012. MATERIALS AND METHODS This was retrospective study done at ORCI by reviewing medical charts of 202 patients with cervical cancer treated at ORCI from January to December 2012. A structured questionnaire was used to extract information about characteristics of the respondents. Survival curves were estimated by using Kaplan-Meir analysis and were compared by using log-rank test. RESULTS The 5-year OS rate was 26%. The mean and median survival times were 33.9 and 19 months, respectively. Factors that were positively associated with 5-year OS rate include t...
