Abstract
Background Cervical cancer is one of the leading causes of cancer death in women, even though it is a preventable disease. Most deaths occur in low- and middle-income countries. In addition to early detection and receipt of standard treatments, survivorship is an important component of high quality of care across the cancer continuum. Objective To assess the survival status of advanced-stage cervical cancer patients after cancer treatment has started. Methods and Materials A one-year prospective cohort study was employed to assess the survival status of women with advanced stages of cervical cancer. A total of 180 cervical cancer patients were recruited, and the study was conducted from January 10, 2022, to September 20, 2023. Data entry and analysis were done in the SPSS 29 version. Descriptive statistics were used to examine participant characteristics. The Kaplan-Meier procedure and log rank test were used to estimate the duration of survival. Bivariate and multivariate Cox regression analyses were computed for predictor variables with survival status. Results Patients receiving cancer treatment at FIGO stages IVA and IVB had survived by 56% and 24%, respectively, whereas patients receiving treatment at stages IIB and IIIA had survived by 100%. The estimated mean survival time at one-year follow-up was 5.706 months (95% CI: 3.785-7.627) for patients with FIGO stage IVB, but 11.537 months (95% CI: 11.199-11.887) for those with stages II and III (P < 0.001). Women over 60 years old had a 1.5-fold higher risk of death than those under 60 (HR: 1.482, P = 0.040). Conclusion The one-year cumulative survival rate among advanced-stage cervical cancer patients was 77%. Major factors associated with survival were age, cancer stage, the presence of anemia, and waiting time for treatment.

Delays in treatment initiation and conclusion in women with stage IA to IIIB cervical cancer: A survival study in a hospital-based cohort from a developing country. Cancer Epidemiol 2023; 86:102450. [PMID: 37678095 DOI: 10.1016/j.canep.2023.102450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 08/24/2023] [Accepted: 08/31/2023] [Indexed: 09/09/2023]
Abstract
AIM To evaluate the effect of delays in stage IA to IIIB cervical cancer treatment initiation and conclusion on hospital-based survival among Brazilian women. METHODS A retrospective follow-up study was conducted in a stage IA to IIIB cervical cancer cohort treated from 2012 and 2014 and followed until December 31, 2017 in Rio de Janeiro. Delay in treatment initiation definition was defined based on the Brazilian law of 60 days for treatment initiation after diagnosis. Delay in treatment conclusion was defined based on the literature and sample distributions: < 120/121-200/> 200 days. The endpoint was death(from all causes or cervical cancer). Death causes and dates were obtained by a record linkage procedure between the hospital cancer registry and the Mortality Information System. Global 36-month survival and HRs were estimated by the KaplanMeier method and proportional Cox regression models, respectively. RESULTS From 865 patients, 269(31.1%) died over the median follow-up time of 27 months. Delay on treatment initiation(>60-days) was 92.8%, while the delay in treatment conclusion(>120 days) was 87.5%. Overall survival was 61.3% (<60-days:62.6%; 61-90 days:63.5%). Among stage IIB-IIIB, women treated < 60-days presented 40.1% survival, while 61-90-days had 52.5%, and > 90-days had 53.3%. Delays in treatment conclusion significantly reduced survival[72.2%(<120-days) to 60.7%(>200-days)]. Multivariate analysis showed that delays in treatment initiation did not affect 36-month death risk. Compared to women concluding treatment in < 120-days, those taking 121-200-days or > 200-days showed increases in death risk of 89%(95%CI:1.10-3.24) and 111%(95%CI:1.31-3.39), respectively, regardless of age, stage, treatment protocol, and time to treatment initiation. CONCLUSION Delays in cervical cancer treatment conclusion (but not treatment initiation) affected 36-month survival and death risk among Brazilians.

Abstract
BACKGROUND Optimal treatment of cervical cancer is based on disease stage; therefore, an understanding of the global epidemiology of specific stages of locally advanced disease is needed. OBJECTIVE This systematic literature review was conducted to understand the global and region-specific proportions of patients with cervical cancer with locally advanced disease and to determine the incidence of the locally advanced disease. METHODS Systematic searches identified observational studies published in English between 2010 and June 10, 2020, reporting the proportion of patients with, and/or incidence of, locally advanced stages of cervical cancer (considered International Federation of Gynecology and Obstetrics (FIGO) IB2-IVA). Any staging criteria were considered as long as the proportion with locally advanced disease was distinguishable. For each study, the proportion of locally advanced disease among the cervical cancer population was estimated. RESULTS The 40 included studies represented 28 countries in North or South America, Asia, Europe, and Africa. Thirty-eight studies reported the proportion of locally advanced disease among populations with cervical cancer. The estimated median proportion of locally advanced disease among all cervical cancer was 37.0% (range 5.6-97.5%; IQR 25.8-52.1%); estimates were generally lowest in North America and highest in Asia. Estimated proportions of ≥50% were reported in nine studies from Asia, Europe, Brazil, and Morocco; estimates ≤25% were reported in six studies from Asia, United States, Brazil, and South Africa. Locally advanced disease was reported for 44% and 49% of women aged >70 and ≥60 years, and 5-100% of younger women with cervical cancer. A greater proportion of locally advanced disease was reported for Asian American (19%) versus White women (8%) in one United States study. Two of five studies describing the incidence of locally advanced disease reported rates of 2-4/100 000 women among different time frames. CONCLUSION This review highlights global differences in proportions of locally advanced cervical cancer, including regional variance and disparities according to patient race and age.

Abstract
Background: Cervical cancer can be invasive and advanced at diagnosis causing devastating suffering and premature death. The cancer stage at presentation is related to survival evaluation and several factors determine stage. The aim of the study was to examine predictors covariates associated with cervical cancer stage at diagnosis and its impact on patient prognosis and survival. Methods: This retrospective cross-sectional study was carried out at Khartoum oncology hospital, Sudan. Participants were 239 cervical cancer patients diagnosed and treated between 2011-2015. Patients’ pathological and socio-demographic data were extracted from their medical files and survival times were calculated from follow-up. Chi-square, Kaplan-Meier, Log-rank test and Cox regression model were used to examine relationships between demographic and clinical variables and survival outcome. Results: The mean age of the participants was 56.91 years and the majority were ≥45 years. Cancer survival analysis showed that the stage at diagnosis had limited association with socio-demographic factors, except where patients reside. Multivariate regression using the Cox proportional hazard model confirmed strongly that stage (p=0.035), chemotherapy (p=0.000) and radiotherapy (p=0.001) were the most likely predictor covariates of patient prognosis and survival time. Conclusions: The results of this study suggest cancer stage at diagnosis and certain treatments are the most important factors impacting the prognosis and survival of patients with cervical cancer. Early detection and vaccination of women against HPV infection provide enormous opportunities for early diagnosis, more effective treatment and better chances of survival.

Abstract
OBJECTIVE The objective of this study was to verify whether the parameters of the blood count and the fasting glucose level before treatment are related to prognosis and survival in cervical cancer (IIB-IVB staging). METHODS Patients with cervical cancer (stages IIB-IVB) were evaluated (n=80). Age, parity, staging, histological grade, histological type, hemoglobin, red blood cells, hematocrit, neutrophil, lymphocyte and platelet counts, red blood cell distribution width, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, fasting glucose levels, overall survival, and disease-free survival were evaluated. The results of laboratory parameters were compared using the Mann-Whitney U test. Receiver operating characteristic curve was used to obtain the area under the curve and determine the best cutoff values for each parameter. Survival was verified by using the Kaplan-Meier method, followed by the log-rank test. The level of significance was ≤0.05. RESULTS Regarding staging, lower hemoglobin values (p=0.0013), red blood cells (p=0.009), hematocrit (p=0.0016), higher leukocytes (p=0.0432), neutrophils (p=0.0176), platelets (p=0.0140), red blood cell distribution width (RDW) (p=0.0073), neutrophil-lymphocyte ratio (p=0.0039), platelet-lymphocyte ratio (p=0.0006), and fasting glucose level (p=0.0278) were found in IIIA-IVB compared with IIB staging. Shorter disease-free survival was associated with hemoglobin ≤12.3 g/dl (p=0.0491), hematocrit ≤38.5% (p=0.05), neutrophil-lymphocyte ratio >2.9 (p=0.0478), and platelet-lymphocyte ratio >184.9 (p=0.0207). Shorter overall survival was associated with hemoglobin ≤12.3 g/dl (p=0.0131), hematocrit ≤38.5% (p=0.0376), neutrophil-lymphocyte ratio >2.9 (p=0.0258), and platelet-lymphocyte ratio >184.9 (p=0.0038). CONCLUSION The analysis of these low-cost and easily accessible parameters could be a way to monitor patients in order to predict treatment failures and act as early as possible.

Abstract
BACKGROUND Cervical cancer survival is marked by socioeconomic and demographic inequalities. We investigated differences in survival across health regions in Minas Gerais, Brazil, in cervical cancer patients who underwent treatment in the Brazilian Public Health System. METHODS From a database developed through probabilistic and deterministic linkage of data from information systems of the Brazilian Public Health System, we identified cervical cancer cases, diagnosed between 2002 and 2010, who underwent radiation and/or chemotherapy and lived in Minas Gerais, Brazil. Five-year overall and cause-specific survivals were estimated by the Kaplan-Meier method and compared using the log-rank test. We used extended Cox models to assess the relationship between the health region of residence and the overall and cause-specific death risk, adjusting for relevant variables. RESULTS We included 5613 patients with a median age of 55.0 years. Median follow-up time was 70.0 months. Five-year overall and cause-specific survivals were 56.3 % and 63.6 %, respectively. Across the 13 health regions, 5-year survival ranged from 46.6%-64.2% (p < 0.001) in the overall analysis and from 52.0% to 72.0% (p < 0.001) in the cause-specific analysis. Multivariate models revealed a significantly higher death risk for most health regions in comparison to the reference health region (Norte). Adjustment by age, tumor stage, comorbidity, treatment, travel time, and year of diagnosis had little effect on the association. CONCLUSION We found regional disparities in cervical cancer survival that persisted after relevant adjustments. Uneven regional provision of health services might be implicated in these disparities, affecting timely access to treatment for cervical cancer patients.

Analysis of the effects of the age-period-birth cohort on cervical cancer mortality in the Brazilian Northeast. PLoS One 2020; 15:e0226258.

Abstract
Cervical cancer (CC) is a public health problem with a high disease burden and mortality in developing countries. In Brazil, areas with low human development index have the highest incidence rates of Brazil and upward temporal trend for this disease. The Northeast region has the second highest incidence of cervical cancer (20.47 new cases / 100,000 women). In this region, the mortality rates are similar to rates in countries that do not have a health system with a universal access screening program, as in Brazil. Thus, this study aimed to analyze the effects of age, period and birth cohorts on mortality from cervical cancer in the Northeast region of Brazil. Estimable functions predicted the effects of age, period and birth cohort. The average mortality rate was 10.35 deaths per 100,000 women during the period analyzed (1980-2014). The highest mortality rate per 100,000 women was observed in Maranhão (24.39 deaths), and the lowest mortality rate was observed in Bahia (11.24 deaths). According to the period effects, only the state of Rio Grande do Norte showed a reduction in mortality risk in the five years of the 2000s. There was a reduction in mortality risk for birth cohorts of women after the 1950s, except in Maranhão State, which showed an increasing trend in mortality risk for younger generations. We found that the high rates of cervical cancer mortality in the states of northeastern Brazil remain constant over time. Even after an increase in access to health services in the 2000s, associated with increased access to the cancer care network, which includes early detection (Pap Test), cervical cancer treatment and palliative care. However, it is important to note that the decreased risk of death and the mortality rates from CC among women born after the 1960s may be correlated with increased screening coverage, as well as increased access to health services for cancer treatment observed in younger women.

Abstract
OBJECTIVE To determine the distribution of sociodemographic, reproductive, clinical and lifestyle habits in the cohort of women diagnosed with cervical cancer, assisted at Inca between 2012 and 2014, according to the histological type. METHODS Retrospective observational study of a hospital cohort of 1,004 women diagnosed with cervical cancer. Data were obtained from the Inca hospital cancer registry, physical and electronic records. RESULTS The most frequent histological type was squamous cell carcinoma (83.9%). Approximately 70% of the women aged more than 40 years. The study includes non-white women (67.4%), with less than 8 years of education (51.9%), with onset of sexual activity up to 16 years of age (40.7%), who were pregnant before (95.5%), with more than one pregnancy (82.9%), and more than two children (52.7%); 45.8% of the women were smokers or former smokers. Cervical adenocarcinoma was positively associated with earlier staging (IA-IIA) (OR = 1.79; 95%CI 1.03–3.13), as well as women with ≥ 12 years of education (OR = 6.30; 95%CI 1.97–20,13), who had no children (OR = 3.81; 95%CI 1.20 – 12,08) or who had up to two children (OR = 1.74; 95%CI 1.05 – 2,87). CONCLUSIONS The difference between histological types is highlighted, suggesting that women with cervical adenocarcinoma may represent a distinct clinical entity of cervical neoplasia, which may require different approaches from those used in squamous cell carcinoma.

Abstract
Abstract Objectives: to evaluate the sociodemographic, clinical, histopathological, cytopathological and microbiological profile of women with cervical cancer treated at Oncology Center in Pernambuco, located in the city of Caruaru-PE. Methods: a retrospective study was carried out to evaluate the medical records of women with cervical cancer treated for radiotherapy and/or chemotherapy between January 2014 and December 2016. For the analysis of variables, the absolute and relative frequencies were calculated. Results: there was a predominance of cases in the age range between 40 and 59 years (45.37%), non-white race/color (91.75%) and incomplete primary education (44.32%). Squamous carcinoma was present in 85.19% of the cases, with a moderately differentiated histological grade being the most common (53.41%). Most women underwent radiotherapy and associated chemotherapy (72.72%) and had 3 or more pregnancies before diagnosis (73.44%). Cytopathology has more frequently identified high-grade squamous intraepithelial lesion (HSIL) cases (45.83%) and cocci and/or bacilli (66.67%) were the most evident microorganisms. Conclusions: the results showed that the perimenopause age, low educational level, multiparity, cytopathologic result of HSIL and histopathological examination evidencing moderately differentiated squamous cell carcinoma were among the characteristics most related to cervical cancer in the population studied.

Abstract
Cervical cancer (CC) is the most common type of cancer in women and is the third leading cause of death in most developing countries, causing more than 288,000 deaths in women worldwide each year. The most favourable survival rate is in developed countries, since CC mortality has recently declined in those countries. The purpose of this study was to determine the survival rate and associated factors of CC patients at a reference hospital in the Amazon region. The patient sample included records of 339 patients with cervical cancer who had been hospitalized in Belém, Pará, Brazil from January 2005 to December 2010; the socioeconomic and clinical data were collected between June and September 2016. A survival rate of approximately 84% was observed, and it was found that disease stage (p <0.01), metastasis (p <0.01) and readmission (p <0.01) had significant influences on patient outcome. The impact of these factors on the general survival rate was higher in the Amazon region compared with other regions of Brazil, and the primary survival factors were associated with earlier stages of the disease. However, more national studies are needed on this subject. Our findings may contribute to the development of regional strategies for the prevention of cervical cancer, a reduction in its incidence and mortality rate, an increase in survival time and an improvement in the quality of life of these women.

Abstract
Overall 5-year survival and factors associated with death were evaluated in a cohort of 342 women with cervical cancer referred to radiotherapy in the Baixada Fluminense, in Greater Metropolitan Rio de Janeiro State, Brazil. Overall 5-year survival was 25.3%, reaching 60.8% in women with stage IIA or less. The model adjusted by extended Cox proportional regression showed an increase in mortality risk for patients with stages IIB-IIIB (HR = 1.89; 95%CI: 1.214; 2.957) and IVA-IVB (HR = 5.78; 95%CI: 2.973; 11.265). Cytology in asymptomatic women (HR = 0.58; 95%CI: 0.362; 0.961) and referral for first consultation in an oncology service in the Baixada Fluminense (HR = 0.60; 95%CI: 0.418; 0.875) were the main protective factors identified by the study. Waiting time (> 60 versus ≤ 60 days) was not statistically significant, but a delay of 4 days worsened the outcome. The 60-day limit for initiating radiotherapy should be respected, because delay greater than 64 days showed a significant association between all waiting time cut-off points and 5-year mortality risk.

Abstract
OBJECTIVE To describe the waiting time for radiotherapy for patients with cervical cancer. METHODS This descriptive study was conducted with 342 cervical cancer cases that were referred to primary radiotherapy, in the Baixada Fluminense region, RJ, Southeastern Brazil, from October 1995 to August 2010. The waiting time was calculated using the recommended 60-day deadline as a parameter to obtaining the first cancer treatment and considering the date at which the diagnosis was confirmed, the date of first oncological consultation and date when the radiotherapy began. Median and proportional comparisons were made using the Kruskal Wallis and Chi-square tests. RESULTS Most of the women (72.2%) began their radiotherapy within 60 days from the diagnostic confirmation date. The median of this total waiting time was 41 days. This median worsened over the time period, going from 11 days (1995-1996) to 64 days (2009-2010). The median interval between the diagnostic confirmation and the first oncological consultation was 33 days, and between the first oncological consultation and the first radiotherapy session was four days. The median waiting time differed significantly (p = 0.003) according to different stages of the tumor, reaching 56 days, 35 days and 30 days for women whose cancers were classified up to IIA; from IIB to IIIB, and IVA-IVB, respectively. CONCLUSIONS Despite most of the women having had access to radiotherapy within the recommended 60 days, the implementation of procedures to define the stage of the tumor and to reestablish clinical conditions took a large part of this time, showing that at least one of these intervals needs to be improved. Even though the waiting times were ideal for all patients, the most advanced cases were quickly treated, which suggests that access to radiotherapy by women with cervical cancer has been reached with equity.
