Obesity and Gynecologic Cancer Etiology and Survival

Author(s):  
Penelope M. Webb

The prevalence of overweight and obesity in the United States and elsewhere has increased dramatically in recent decades. It has long been known that obese women have an increased risk of developing endometrial cancer, but recent studies suggest this association is strongest for the most common low-grade endometrioid endometrial cancers and weaker for the other histologic subtypes. There are insufficient data to assess whether obesity affects endometrial cancer-specific survival or whether the relation with all-cause mortality is similar to that seen in the general population. Recent data suggest obesity also increases risk of ovarian cancer, although it may not influence risk of the high-grade serous cancers that account for the majority of ovarian cancer deaths, and that it is also associated with poorer outcomes. There is currently insufficient evidence to draw any clear conclusions regarding the relation between obesity and risk of/survival from other gynecologic cancers although there are suggestions that obesity may increase risk of cervical cancer, particularly adenocarcinoma, and perhaps vulvar cancer. Possible mechanisms whereby obesity might influence gynecologic cancer risk and survival include: its strong association with endogenous estrogen levels among postmenopausal women, its effects on glucose metabolism, its effects on the wide range of adipocytokines and inflammatory mediators that are produced by adipose tissue and altered in concentration among obese individuals, and its potential effects on patient management, particularly with regard to chemotherapy dosing.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States and is the country’s fifth most common cause of cancer mortality in women. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. These NCCN Guidelines discuss cancers originating in the ovary, fallopian tube, or peritoneum, as these are all managed in a similar manner. Most of the recommendations are based on data from patients with the most common subtypes─high-grade serous and grade 2/3 endometrioid. The NCCN Guidelines also include recommendations specifically for patients with less common ovarian cancers, which in the guidelines include the following: carcinosarcoma, clear cell carcinoma, mucinous carcinoma, low-grade serous, grade 1 endometrioid, borderline epithelial, malignant sex cord-stromal, and malignant germ cell tumors. This manuscript focuses on certain aspects of primary treatment, including primary surgery, adjuvant therapy, and maintenance therapy options (including PARP inhibitors) after completion of first-line chemotherapy.

This chapter focuses on the three types of gynecologic cancer—epithelial cancer of the ovary, cancer of the uterine cervix, and cancer of the endometrium (uterine cancer)—and reviews their epidemiology, diagnosis, differential diagnosis, surgical features, and staging, as well as their risk factors and clinical features. Also discussed are methods of treatment and the management of relapse. Epithelial ovarian cancer occurs at a mean age of 60 years in the United States and is the most lethal of gynecologic tract tumors. However, a recent trial has demonstrated a survival advantage through the use of intraperitoneal chemotherapy for appropriate patients with optimally debulked ovarian cancer. Invasive cervical cancer is uncommon in developed countries, partly because of the effectiveness of Pap smear screening. Nevertheless, cancer of the uterine cervix is the third most common gynecologic cancer diagnosis and cause of death among gynecologic cancers in the United States. However, for women with early-stage cervical cancer, data from several randomized trials indicate an improvement in response rate and survival through the use of combination platinum-based regimens for platinum-sensitive relapse. Also noted is an improvement in survival using combined-modality chemoradiation in appropriate patients with locally advanced cervical cancer. Endometrial cancer is the most frequent tumor of the gynecologic tract; it is estimated that it occurred in over 46,000 women and caused more than 8,000 deaths in the United States in 2011. Recent data indicate improvement in survival using adjuvant platinum-based chemotherapy in appropriate patients with high-risk endometrial cancer. Tables in this chapter review the common histologic types of epithelial ovarian cancer, selected signs and symptoms of ovarian cancer, the International Federation of Gynecology and Obstetrics (FIGO) staging system for epithelial ovarian cancer, differential diagnosis of a complex cyst detected by transvaginal sonography, selected adverse prognostic factors in epithelial ovarian cancer, common chemotherapy agents used in the treatment of epithelial ovarian cancer, the FIGO surgical staging of endometrial cancer, and postoperative management considerations for patients with uterine cancer. Figures illustrate the four histologic subtypes of epithelial ovarian cancer, the intraoperative appearance of stage III epithelial ovarian cancer, and FIGO staging of cervical cancer. This review contains 6 highly rendered figures, 8 tables, and 150 references.

We conducted a retrospective cohort study to evaluate the subsequent colorectal cancer (CRC) risk for women with gynecologic malignancy using insurance claims data of Taiwan. We identified patients who survived cervical cancer (N = 25,370), endometrial cancer (N = 8149) and ovarian cancer (N = 7933) newly diagnosed from 1998 to 2010, and randomly selected comparisons (N = 165,808) without cancer, matched by age and diagnosis date. By the end of 2011, the incidence and hazard ratio (HR) of CRC were estimated. We found that CRC incidence rates were 1.26-, 2.20-, and 1.61-fold higher in women with cervical, endometrial and ovarian cancers, respectively, than in comparisons (1.09/1000 person–years). The CRC incidence increased with age. Higher adjusted HRs of CRC appeared within 3 years for women with endometrial and ovarian cancers, but not until the 4th to 7th years of follow up for cervical cancer survivals. Cancer treatments could reduce CRC risks, but not significantly. However, ovarian cancer patients receiving surgery alone had an incidence of 3.33/1000 person–years for CRC with an adjusted HR of 3.79 (95% CI 1.11–12.9) compared to patients without any treatment. In conclusion, gynecologic cancer patients are at an increased risk of developing CRC, sooner for those with endometrial or ovarian cancer than those with cervical cancer.

Whilst previous studies have reported that higher BMI increases a woman's risk of developing ovarian cancer, associations for the different histological subtypes have not been well defined. As the prevalence of obesity has increased dramatically, and classification of ovarian histology has improved in the last decade, we sought to examine the association in a pooled analysis of recent studies participating in the Ovarian Cancer Association Consortium. We evaluated the association between BMI (recent, maximum and in young adulthood) and ovarian cancer risk using original data from 15 case–control studies (13 548 cases and 17 913 controls). We combined study-specific adjusted odds ratios (ORs) using a random-effects model. We further examined the associations by histological subtype, menopausal status and post-menopausal hormone use. High BMI (all time-points) was associated with increased risk. This was most pronounced for borderline serous (recent BMI: pooled OR=1.24 per 5 kg/m2; 95% CI 1.18–1.30), invasive endometrioid (1.17; 1.11–1.23) and invasive mucinous (1.19; 1.06–1.32) tumours. There was no association with serous invasive cancer overall (0.98; 0.94–1.02), but increased risks for low-grade serous invasive tumours (1.13, 1.03–1.25) and in pre-menopausal women (1.11; 1.04–1.18). Among post-menopausal women, the associations did not differ between hormone replacement therapy users and non-users. Whilst obesity appears to increase risk of the less common histological subtypes of ovarian cancer, it does not increase risk of high-grade invasive serous cancers, and reducing BMI is therefore unlikely to prevent the majority of ovarian cancer deaths. Other modifiable factors must be identified to control this disease.

ABSTRACTRecurrentClostridium difficileinfection (rCDI) frequently complicates recovery from CDI. Accurately predicting rCDI would allow judicious allocation of limited resources, but published models have met with limited success. Thus, biomarkers predictive of recurrence have been sought. This study tested whether PCR ribotype independently predicted rCDI. Stool samples from nonpregnant inpatients ≥18 years of age with diarrhea were included from October 2010 to January 2013 after the patients tested positive forC. difficilein the clinical microbiology laboratory. Per guidelines, the rCDI was defined as a positive test forC. difficileat >2 weeks but ≤8 weeks from the index episode. For each sample, a single colony ofC. difficilewas isolated by anaerobic culture, confirmed to be toxigenic by PCR, and ribotyped. Simple logistic regression and multiple logistic regression were used to model the primary outcome of rCDI, incorporating a wide range of clinical parameters. In total, 927 patients with 968 index episodes of CDI were included, with 110 (11.4%) developing rCDI. Age and use of proton pump inhibitors or concurrent antibiotics did not increase the risk of rCDI. Low serum bilirubin levels and ribotype 027 were associated with increased risk of rCDI on unadjusted analysis, with health care-associated CDI being inversely associated. In the final multivariable model, ribotype 027 was the strongest independent predictor of rCDI (odds ratio, 2.17; 95% confidence interval, 1.33 to 3.56;P= 0.002). Ribotype 027 is an independent predictor of rCDI.IMPORTANCECDI is a major public health issue, with over 400,000 cases per year in the United States alone. Recurrent CDI is common, occurring in approximately one in five individuals after a primary episode. Although interventions exist that could reduce the risk of recurrence, deployment in all patients is limited by cost, invasiveness, and/or an undetermined long-term safety profile. Thus, clinicians need risk stratification tools to properly allocate treatments. Because prior research on clinical predictors has failed to yield a reliable, reproducible, and effective predictive model to assist treatment decisions, accurate biomarkers of recurrence would be of great value. This study tested whether PCR ribotype independently predicted rCDI, and the data build upon prior research in showing that ribotype 027 is associated with rCDI.

Persons who inject drugs (PWID) are at increased risk for overdose death (ODD), infections with HIV, hepatitis B (HBV) and hepatitis C virus (HCV), and noninfectious health conditions. Spatiotemporal identification of PWID communities is essential for developing efficient and cost-effective public health interventions for reducing morbidity and mortality associated with injection-drug use (IDU). Reported ODDs are a strong indicator of the extent of IDU in different geographic regions. However, ODD quantification can take time, with delays in ODD reporting occurring due to a range of factors including death investigation and drug testing. This delayed ODD reporting may affect efficient early interventions for infectious diseases. We present a novel model, Dynamic Overdose Vulnerability Estimator (DOVE), for assessment and spatiotemporal mapping of ODDs in different U.S. jurisdictions. Using Google® Web-search volumes (i.e., the fraction of all searches that include certain words), we identified a strong association between the reported ODD rates and drug-related search terms for 2004–2017. A machine learning model (Extremely Random Forest) was developed to produce yearly ODD estimates at state and county levels, as well as monthly estimates at state level. Regarding the total number of ODDs per year, DOVE’s error was only 3.52% (Median Absolute Error, MAE) in the United States for 2005–2017. DOVE estimated 66,463 ODDs out of the reported 70,237 (94.48%) during 2017. For that year, the MAE of the individual ODD rates was 4.43%, 7.34%, and 12.75% among yearly estimates for states, yearly estimates for counties, and monthly estimates for states, respectively. These results indicate suitability of the DOVE ODD estimates for dynamic IDU assessment in most states, which may alert for possible increased morbidity and mortality associated with IDU. ODD estimates produced by DOVE offer an opportunity for a spatiotemporal ODD mapping. Timely identification of potential mortality trends among PWID might assist in developing efficient ODD prevention and HBV, HCV, and HIV infection elimination programs by targeting public health interventions to the most vulnerable PWID communities.

This article presents reviews of literature sources on the issue of assessing the risk of developing gynecological cancer in women after an in vitro fertilization program. Infertility and infertile marriages have now become quite a big problem of modern medicine. Against the background of the unfavorable demographic situation in the Russian Federation, this problem is becoming quite urgent. The main way to solve this situation is assisted reproductive technologies, among which the most common is in vitro fertilization. The in vitro fertilization program is accompanied by a hormonal ovulation stimulation procedure to obtain a female germ cell capable of fertilization. Against the background of the active use of the in vitro fertilization procedure, many patients had concerns related to the risk of developing gynecological cancer after the IVF procedure, which is due to the use of hormonal drugs to stimulate the ovaries. Also of concern is the fact that certain types of cancer, including ovarian cancer, endometrial cancer and breast cancer, are hormone-dependent. In this regard, multiple large-scale studies were conducted, which showed that the risk of developing gynecological cancer is really increased in patients after the in vitro fertilization program. In particular, breast cancer in women after the in vitro fertilization program is more common by 10%, and in women without a history of pregnancy and over the age of 40, it is more common by 31%. The increased risk may be due to age-related vulnerability to the effects of hormones or higher doses of hormones during the IVF procedure. Ovarian cancer and endometrial cancer are also more common in patients after IVF. According to the research results, it is suggested that it is not the IVF procedure itself that causes the development of cancer, but excessive hormonal load of the body, which leads to the launch of carcinogenesis.

Endometrial cancer is the most common gynecologic cancer and is predominantly endocrine-related. The role of unopposed estrogen in the development of endometrial cancer has been investigated in numerous studies. Different reproductive factors such as younger age at menarche, late age at menopause, infertility, nulliparity, age of birth of the first child, and long-term use of unopposed estrogens during hormone replacement therapy have been associated with an increased risk of endometrial cancer. In contrast, there is a growing body of evidence for a protective role of oral contraceptives. Most of the published data on the association between infertility and polycystic ovary syndrome are inconclusive, whereas the effect of tamoxifen on the risk of endometrial cancer has been well established. With this review, we aim to summarize the evidence on the association between infertility, polycystic ovary syndrome, oral contraceptives, and tamoxifen and the development of endometrial cancer.

Endometrial cancer is the most common gynecologic malignancy in the United States and the sixth most common cancer in women worldwide. Fortunately, most women who develop endometrial cancer have low-grade early-stage endometrioid carcinomas, and simple hysterectomy is curative. Unfortunately, 15% of women with endometrial cancer will develop high-risk histologic tumors including uterine carcinosarcoma or high-grade endometrioid, clear cell, or serous carcinomas. These high-risk histologic tumors account for more than 50% of deaths from this disease. In this review, we will highlight the biologic differences between low- and high-risk carcinomas with a focus on the cell of origin, early precursor lesions including atrophic and proliferative endometrium, and the potential role of stem cells. We will discuss treatment, including standard of care therapy, hormonal therapy, and precision medicine-based or targeted molecular therapies. We will also discuss the impact and need for model systems. The molecular underpinnings behind this high death to incidence ratio are important to understand and improve outcomes.
