Abstract
OBJECTIVE Mode of delivery has long-term implications on the mother, including recent data regarding the level of transmission of fetal microchimeric cells (FMc) and their possible effect on cancer development. We aimed to evaluate the association between cesarean section (CS) and future risk for neoplasms. STUDY DESIGN A population-based cohort analysis comparing the long-term risk for neoplasms between patients that delivered only by CS to those that delivered only vaginally (VD). Neoplasms were pre-defined based on ICD-9 codes. Deliveries occurred between the years 1991-2017 in a tertiary medical center. Kaplan-Meier survival curves were used to compare the cumulative incidence of neoplasms and Cox proportional hazards models were constructed to control for confounders. RESULTS During the study period 105,992 patients met the inclusion criteria; 14150 (13.4%) of patients had only CS and 91842 (86.6%) had VD (comparison group). The CS group had significantly higher incidence of benign and malignant neoplasms (4.73 per 1000 patient-years versus 3.88 per 1000 patient-years, OR = 1.26, 95% CI 1.16-1.37; p = 0.001; 2.19 per 1000 patient-years of follow up versus 1.93 per 1000 patient-years, OR = 1.16, 95% CI 1.03-1.31; p = 0.013). Specifically, the CS group had higher incidence of uterine cancer (1.2 versus 0.06 per 1000 patient-years, OR = 1.97, 95% CI 1.14-3.39; p = 0.013). The cumulative incidence of benign, malignant and uterine neoplasms was significantly higher in the CS group (Log rank test p = 0.001; 0.036 and 0.014; respectively). Importantly, no significant association was found with breast and ovarian malignancies." When performing a Cox regression model controlling for confounders, the risk for malignancy-related hospitalizations remained significant (adjusted HR = 1.22, 95% CI 1.01-1.48; p = 0.031) but not for uterine cancer (adjusted HR = 1.6, 95% CI 0.9-2.8; p = 0.103). CONCLUSION Our findings provide support to linkage between delivery by cesarean section and future maternal malignancy.

[PMID: 37480027 PMCID: PMC10362563 DOI: 10.1186/s12905-023-02535-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 07/09/2023] [Indexed: 07/23/2023] Open
Abstract
BACKGROUND Uterine cancer remains a serious medical problem worldwide. This study aimed to explore the global time trends of uterine cancer burden using the age-period-cohort model and forecast incidence to 2044. METHODS Data were downloaded from the Global Burden of Disease 2019. The age-period-cohort model was used to estimate age, period and birth cohort effects. We also predict uterine cancer incidence to 2044. RESULTS Globally, there were 435,041 incident cases (95% UI: 245,710 to 272,470) and 91,640 deaths of uterine cancer (95% UI: 39,910 to 44,140) in 2019. During the past 30 years, the age-standardized incidence and death rates increased by 15.3% and decreased by 21.6%, respectively. Between 1990 and 2019, the high-sociodemographic index region had the highest overall annual percentage changes. The age effect showed the uterine cancer incidence rate first increased and then decreased with age. The period and cohort relative rate ratio showed upward trends during the study period. Incident cases of uterine cancer may increase to more than six hundred thousand in 2044. CONCLUSION Uterine cancer causes a high disease burden in high-income regions and the global incidence may continue to increase in the future. Improving awareness of risk factors and reducing the proportion of the obese population are necessary to reduce future burden.

Abstract
BACKGROUND Pre-eclampsia may be associated with the development of endometrial cancer; however, previous findings have been conflicting. OBJECTIVES To investigate if pre-eclampsia is associated with an increased risk of endometrial cancer. METHOD Two independent reviewers screened titles and abstracts of studies identified in MEDLINE, Embase, and Web of Science databases from inception until March 2022. Studies were included if they investigated pre-eclampsia and subsequent risk of endometrial cancer (or precursor lesions). Random-effects meta-analysis was used to calculate pooled hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between pre-eclampsia during pregnancy and endometrial cancer risk. MAIN RESULTS There were seven articles identified which investigated endometrial cancer, of which one also investigated endometrial cancer precursors. Overall, the studies include 11,724 endometrial cancer cases. No association was observed between pre-eclampsia and risk of endometrial cancer with moderate heterogeneity observed (pooled HR 1.07, 95% CI 0.79-1.46, I2 = 34.1%). In sensitivity analysis investigating risk of endometrial neoplasia (atypical hyperplasia, carcinoma in situ, or cancer), there was some evidence that pre-eclampsia was associated with an increased risk (HR 1.34, 95% CI 1.15-1.57, I2 = 29.6%). CONCLUSIONS Pre-eclampsia was not associated with an increased risk of endometrial cancer. Additional large studies with information on pre-eclampsia sub-type aiming to investigate endometrial cancer precursor conditions are merited.

Abstract
Gynecological cancers, the most common cancer among women worldwide, disrupt the function of women's reproductive system, significantly impacting the quality of life. The epidemiological patterns of gynecological cancers differ in various regions and alter over time. The main challenge to deal with women's cancers is focusing on potential plans to improve patient outcomes. The epidemiology and general risk elements of gynecological cancers are important in the management of these cancers, so all of the reported risk factors in gynecological cancers have been evaluated in the present review. Due to the role of gynecological cancers in women's health, preventive measures and modifiable lifestyles together with early detection in high-risk groups are effective strategies that can reduce mortality rates. This review summarizes the epidemiology and global risk factors of gynecological cancers alongside others to better management of these malignancies and improve the quality of life in the affected patients.

Abstract
IMPORTANCE Results of this work may provide some guidance for subsequent ovarian cancer screening in women with preeclampsia and provide new directions for future studies. OBJECTIVE This study investigated the difference in cancer risk between women with preeclampsia and women with a normal pregnancy. EVIDENCE REVIEW Electronic databases, namely PubMed, Embase, and the Cochrane Library, were searched for relevant studies from database inception to February 4, 2021. The results are expressed as risk ratios (RRs). FINDINGS The study included 13 cohort studies comprising 5,254,150 participants. The difference in the total cancer risk between the control and preeclampsia groups was statistically nonsignificant. However, breast cancer (BC) risk was lower in the preeclampsia group (RR = 0.88, 95% confidence interval (CI) = 0.83-0.93; I2 = 57.2%). A subgroup analysis stratified by reproductive factors demonstrated that BC risk in the preeclampsia population decreased in parous women (RR = 0.79, 95% CI = 0.72-0.87; I2 = 0%), women with full-term pregnancies (RR = 0.79, 95% CI = 0.75-0.84; I2 = 0%), and women with increasing parity. Furthermore, BC risk reduced in women with preeclampsia regardless of their menopausal status and the sex of their offspring. CONCLUSIONS AND RELEVANCE Overall, women with preeclampsia have a decreased BC risk and increased ovarian cancer risk compared with the normal population. A subgroup analysis stratified by reproductive factors demonstrated that BC risk decreased in the preeclampsia population in parous women, women with full-term pregnancies, and women with increasing parity regardless of their menopausal status and the sex of their offspring.

Abstract
Macrosomia, usually defined as infant birth weight of ≥4000 g, does not consider gestational age, sex, or country/region-specific differences in mean birth weight and maternal body weight. This issue is particularly relevant for Asia, where 60% of the world's population lives, due to variations in maternal size and birth weights across populations. Large for gestational age (LGA), defined as birth weight > 90th centile, is a more sensitive measure as it considers gestational age and sex, though it is dependent on the choice of growth charts. We aimed to review reporting of macrosomia and LGA in Asia. We reviewed the literature on prevalence and risk of macrosomia and LGA in Asia over the last 29 years. Prevalence of macrosomia ranged from 0.5% (India) to 13.9% (China) while prevalence of LGA ranged from 4.3% (Korea) to 22.1% (China), indicating substantial variation in prevalence within and between Asian countries. High pre-pregnancy body mass index, excessive gestational weight gain, and impaired glucose tolerance conferred risk of macrosomia/LGA. Incidence of macrosomia and LGA varies substantially within and between Asian countries, as do the growth charts and definitions. The latter makes it impossible to make comparisons but suggests differences in intrauterine growth between populations. Reporting LGA, using standardized country/regional growth charts, would better capture the incidence of high birth weight and allow for comparison and identification of contributing factors. Better understanding of local drivers of excessive intrauterine growth could enable development of improved strategies for prevention and management of LGA.
