Abstract
PURPOSE/OBJECTIVE(S) Chemoradiation (CRT) remains the standard of care for locally advanced cervical cancer. As recent large phase III trials (OUTBACK, CALLA) reported no difference in primary survival outcomes when novel agents were added to CRT, technological advancements continue to be a focus for improving outcomes. Daily imaging has enabled margin reduction on the cervix, uterus and lymph nodes, which can lower radiation dose to bowel and potentially reduce RT-related symptoms. Daily adaptive RT (ART) combines daily imaging with online dosimetry replanning, allowing for decreased margins on the target. A pre-planning study showed bowel V40Gy and V45Gy reductions of 252 cc to140 cc and 167 cc to 43 cc, respectively. ARTIA-Cervix is a single-arm, prospective, multi-institutional, international clinical trial investigating the potential of ART to decrease patient-reported acute gastrointestinal (GI) toxicity. MATERIALS/METHODS Planned enrollment is 125 subjects with up to 8 sites participating. Eligibility criteria include locally advanced node-negative cervical cancer FIGO stages IB2-3B. Treatment will consist of cisplatin-based CRT with daily ART, followed by image-guided brachytherapy. Subjects will receive 25 fractions ART at 1.8 Gy per day for a total of 45 Gy. The primary study objective is reduction of patient-reported GI toxicity as measured by PRO-CTCAE score ≥3 at the conclusion of ART. Secondary objectives include patient-reported GU toxicity and sexual quality of life, the development of radiation dosimetry models predicting toxicity, physician-reported toxicities, 2-year disease free survival, and adaptive workflow metrics. Powering of the study and sample size calculation are based on the hypothesis that ART will decrease patient-reported acute GI toxicity from historical rates of 33% to 20% (13% effect size). RESULTS This study opened to enrollment on April 28th, 2022. The total study duration will be approximately 5 years. CONCLUSION ARTIA-Cervix is an international, prospective clinical trial designed to evaluate reduction of treatment-related GI toxicity through daily online ART. The results of this clinical study will add to the growing body of evidence supporting clinical decisions about utilization of ART technologies.

Abstract
PURPOSE/OBJECTIVE(S) Concurrent chemo-radiotherapy is commonly prescribed for muscle-invasive bladder cancer (MIBC). Post hoc analysis of two large, randomized trials found that hypofractionation improves loco-regional control (LRC) vs. standard fractionation in this population. A challenge in traditional image-guided radiotherapy of the bladder is that daily changes in bladder position and size requires large margins to ensure target coverage. This makes it difficult to spare uninvolved bladder from high-dose treatment, increases the risk of bowel toxicity, and results in historical rates of acute G3+ toxicity exceeding 20-30%. Daily online adaptive RT (ART) may enable reduced, personalized margins that maintain target coverage while reducing dose to OARs. This prospective clinical trial will test whether: 1) participants undergoing ART for MIBC have a lower rate of acute G3+ GI/GU toxicity compared with the 31% historical control rate (Stage III BC2001 trial), and 2) 2-year LRC with ART will be non-inferior to historical controls (75%). MATERIALS/METHODS This multi-national trial will enroll 165 adult subjects with stage cT2-T4aN0M0 urothelial MIBC. Subjects will have undergone an attempt at maximal transurethral resection of bladder tumor. Patients with clinically involved nodes or G2+ GI or G3+ GU symptoms/conditions at baseline are ineligible. Concurrent with chemotherapy, participants will receive (at the discretion of the investigator) either 55 Gy in 20 fx to whole-bladder or 46 Gy in 20 fx to whole-bladder plus simultaneous in-field boost of 55 Gy in 20 fx to tumor bed. A personalized ITV will be derived for each subject based on bladder expansion, as assessed on two CT simulations separated by 30 min. Daily ART will be attempted for all subjects. The primary endpoint is acute G3+ GI/GU toxicity. Secondary endpoints are LRC; quality of life (EORTC QLQ-BLM30, EPIC 26 bowel and urinary); global function (EQ-5D-5L ); 2-year disease-free, bladder intact event-free, and overall survival; 2-year bladder cancer-specific mortality; NTCP model of acute GI toxicity for hypofractionated bladder RT; workflow feasibility of ART; improved target coverage ± reduced dose to critical OARs vs. non-ART dosimetry; acute G3+ GI/GU toxicity rate in subjects with ≥75% of their treatments as ART; and acute G3+ GI/GU toxicity in the cohort treated with partial bladder boost. Exploratory translational and correlative endpoints will also be examined. RESULTS This trial opened to enrollment on Feb 2, 2023; the study duration is expected to be 4-5 years. CONCLUSION This prospective clinical trial will provide robust clinical data to inform healthcare providers' decisions on the use of daily online ART and hypofractionation as a bladder preservation strategy for this population.

Abstract
PURPOSE/OBJECTIVE(S) Radiotherapy (RT) with concurrent chemotherapy is a standard treatment for Stage III NSCLC. However, radiation pneumonitis incidence increases rapidly with volume of lung irradiated, and esophagitis increases with dose to the esophagus. Both conditions can have adverse impacts on patients' quality of life. Daily online adaptive RT (ART) may allow for reduced normal tissue doses due to smaller margins around the target, as well as target size reduction with tumor response. This prospective, randomized controlled trial tests the hypothesis that the proportion of study participants who experience score ≥3 PRO-CTCAE cough, dyspnea, or dysphagia will be at least 20% lower with daily ART than with non-adapted RT. MATERIALS/METHODS Enrollment goals are 244 subjects at up to 10 cancer centers worldwide. Eligibility criteria include stage IIIA-IIIC (AJCC v8) NSCLC; baseline grade 0-2 dyspnea, cough, and dysphagia; and no contralateral hilar or supraclavicular/cervical lymph node involvement. Subjects will be randomized (1:1) to CBCT-based daily ART or non-adapted RT using IMRT or VMAT delivering 60-66 Gy in 30-33 fractions with concurrent platinum doublet chemotherapy. Adjuvant immunotherapy with durvalumab is permitted. Follow-up for study participants will be for 1-year post-completion of chemoRT. Study endpoints include: frequency of PRO-CTCAE score ≥3 cough, dyspnea, or dysphagia from randomization to 30 days post-chemoRT; patient-reported quality of life (FACT-L and EQ-5D-5L questionnaires); percentage of lung receiving ≥20 Gy; mean doses to lung, heart, and esophagus; primary tumor response on CT or PET-CT (RECIST v1.1); local disease progression; and incidence of grade ≥2 pneumonitis within 1 year. Stratification factors are the treating institution and the presence of contralateral mediastinal lymph node metastases (associated with increased volume of irradiated lung). Interim analyses for futility and superiority will be performed when the primary endpoint data have been collected for 50% of evaluable participants. RESULTS This study opened to enrollment on 20 October 2022 and is expected to be completed in approximately 3 years. CONCLUSION This prospective, randomized clinical trial rigorously evaluates the impacts of daily online ART on radiation pneumonitis, esophagitis, and quality of life in patients with advanced NSCLC. It will collect standard tumor response and disease progression metrics to assure that reduced margins do not have an adverse impact on outcomes. Online ART is emerging as an innovative approach enabling increased sparing of normal tissues. The results of this clinical study will support evidence-based clinical decisions around ART technologies.

Does the environment affect menopause? A review of the effects of endocrine disrupting chemicals on menopause. Climacteric 2023; 26:206-215.

Abstract
Endocrine disrupting chemicals are widely distributed in our environment. Humans are exposed to these compounds not only through their occupations, but also through dietary consumption and exposure to contaminated water, personal care products and textiles. Chemicals that are persistent in the body and in our environment include dioxins and polychlorinated biphenyls. Non-persistent chemicals including bisphenol A, phthalates and parabens are equally as important because they are ubiquitous in our environment. Heavy metals, including lead and cadmium, can also have endocrine disrupting properties. Although difficult to study due to their variety of sources of exposures and mechanisms of action, these chemicals have been associated with early menopause, increased frequency of vasomotor symptoms, altered steroid hormone levels and markers of diminished ovarian reserve. Understanding the impacts of these exposures is important given the potential for epigenetic modification, which can alter gene function and result in multi-generational effects. This review summarizes findings in humans and animals or cell-based models from the past decade of research. Continued research is needed to assess the effects of mixtures of chemicals, chronic exposures and new compounds that are continuously being developed as replacements for toxic chemicals that are being phased out.

Abstract
5578 Background: Endometrial cancer at this time is predominantly being looked at as a disease of postmenopausal population. Increased obesity has been identified as an important risk factor for endometrial cancer. An overall increase incidence of endometrial hyperplasia and endometrial carcinoma in obese premenopausal women has been reported. A close examination of the relationship between trends in endometrial cancer incidence and obesity prevalence in young women will provide important information for prevention and early screening of the disease and its precursors. This study was to assess current trends in endometrial cancer incidence in women ages 20-29 and 30-39 years in relationship to obesity in the US. Methods: We used data on US adult women 20-39 years old from the National Program for Cancer Registries and Surveillance, Epidemiology, and End Results Incidence–U.S. Cancer Statistics 2001–2017 database. This database covered essentially all young female population between 2001 and 2017 in the US (Puerto Rico not included). Incidence was age adjusted to the 2020 U.S. standard population. We also examined the trends in obesity prevalence among females 18-34 years old using data from the National Health and Nutrition Examination Survey (NHANES) III and NHANES 1999-2014. Results: There were 24,446 cases of endometrial cancer among young adult women aged 20-39 years during 2001-2017. Endometrial cancer incidence increased from 0.6 per 100,000 in 2001 to 1.2 per 100,000 in 2017 (APC 3.6, 95% CI 2.9-4.4) among young women 20-29 years old, and increased from 4.6 per 100,000 in 2001 to 7.5 per 100,000 in 2017 (APC 3.0, 95% CI 2.7-3.3) among women 30-39 years old. Obesity prevalence also increased significantly from 1988-2014 among females 18-34 years old. Incidence of endometrial cancer and obesity prevalence were both higher in Hispanics than in other racial/ethnic groups. Conclusions: The significant increasing incidence in endometrial cancer among young adult women is in accordance with the concurrent increasing prevalence in obesity in young girls and women in the US. This indicates that endometrial cancer screening might need to be considered at much earlier age among patients with abnormal bleeding and certain ethnic populations.

Abstract
INTRODUCTION BRCA mutation testing has been used for screening women at high risk of breast and ovarian cancer and for selecting the best treatment for those with breast cancer. To optimize the infrastructure and medical resources allocation for genetic testing, it is important to understand the use of BRCA mutation testing in the U.S. health system. METHODS This retrospective cohort study included 53,254 adult women with insurance claims for BRCA mutation testing between 2004 and 2014 from ClinformaticsTM Data Mart Database. Data analysis was performed in 2016. This study assessed trends in the use of BRCA mutation testing in women with previously diagnosed breast or ovarian cancer and those without (unaffected women). RESULTS Between 2004 and 2014, of those receiving BRCA testing, the proportion of BRCA tests performed in unaffected women increased significantly (p<0.001), from 24.3% in 2004 to 61.5% in 2014. An increase in the proportion of BRCA tests used in unaffected women was found in each characteristic subgroup. In 2014, most subgroups had a proportion surpassing 50%, except for those aged 51-65 years and those without a family history of breast cancer. There was a much lower proportion of those aged 20-40 years among tested women with previously diagnosed breast or ovarian cancer than in unaffected women (17.6% vs 41.7%, p<0.001). CONCLUSIONS During the past decade, the role of BRCA testing has gradually shifted from being used primarily in cancer patients to being used in unaffected women in the U.S.

Abstract
BACKGROUND Standard-of-care (SOC) cancer treatments are primarily aimed at reducing size and progression of a tumor. There is a need for successful supplemental anabolic therapies to combat cancer cachexia in addition to these SOC treatment modalities. Anabolic interventions, including testosterone and amino acid supplements, may be beneficial in reducing and/or reversing muscle wasting in these patient populations. METHODS A 48-year-old Caucasian female with recurrent cervical cancer was scheduled to receive three 21-day cycles of cisplatin and topetecan chemotherapy. She qualified, consented, and enrolled into a blinded interventional pilot study where she received daily whey protein (10 g, three times per day with meals) and a weekly injection of testosterone enanthate (100 mg intramuscular) before and during the SOC chemotherapy treatment period. Body composition, serum inflammatory markers, mixed muscle protein synthesis and breakdown rates, physical function, fatigue, and quality of life were assessed before and after the intervention period. RESULTS Body composition, as assessed by an increase in body weight and lean body mass and reduction in fat mass; physical function; fatigue; and quality of life each improved across the entire intervention period despite general increases in inflammatory markers and no improvements in muscle protein turnover towards the end of the intervention. CONCLUSIONS Concomitant treatment of oral amino acids and testosterone may be a viable therapeutic option for fighting cachexia and improving body composition and quality of life during chemotherapeutic treatment of recurrent cervical cancer. These positive outcomes may be attainable over time despite overall poor inflammatory status.

Abstract
High-risk human papillomavirus (H-HPV) infection is strongly linked to cervical neoplasia, but its role in detecting glandular lesions (GLs) is unclear. In the cervix, carbonic anhydrase IX (CA-IX) is expressed in cervical neoplasia, but rarely in the benign cervix. The diagnostic utility of these biomarkers was evaluated in women with a cytologic diagnosis of atypical glandular cells (AGC). H-HPV was detected using hybrid capture 2 (HC2) in liquid-based cytology, and CA-IX immunoreactivity was studied on conventional Pap smears. Of 403 patients, 111 (28%) were positive for significant cervical lesions (SCLs) including CIN2, CIN3, adenocarcinoma in situ or invasive carcinoma. CA-IX testing alone (n = 403) had a sensitivity of 75, 95 or 65% for SCLs, significant GLs or squamous lesions (SLs), respectively, with a specificity of 88% and a false negative rate (FNR defined as 1 minus negative predictive value) of 10%. Testing for H-HPV (n = 122) had a sensitivity of 97, 100 or 96% for SCLs, GLs or SLs, respectively, with a specificity of 87% and a FNR of 1%. The combination of CA-IX and H-HPV testing (n = 122), collectively, had the same sensitivity, specificity and FNR for SCLs, GLs or SLs as H-HPV testing alone. The conclusions of our study are that both H-HPV and CA-IX testing are useful diagnostic markers for GLs. However, H-HPV testing is a better diagnostic marker for SLs. The combination of CA-IX with H-HPV testing does not improve the diagnostic accuracy for cervical neoplasia in women with AGC diagnosis over that of H-HPV testing alone.

Abstract
Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

Abstract
The generation of electricity through the use of radioactive material at the nuclear power plant is inevitably associated with the production of wastes, some of which have potential impact on the biosphere. The objective of the present investigation was to provide information for evaluating the presumed impact of the Mexican Nuclear Power Plant "Laguna Verde" on the natural populations. Two sibling species that live in the immediate vicinity, Drosophila melanogaster and D. simulans have been studied for several traits in a long term study. The present study describes results for the desiccation resistance (DR) trait obtained during the period from 1995 to 2002. Flies were collected at two sites, one near the reactors and another farther away. The data obtained confirmed that D. melanogaster had higher DR values than D. simulans at both sites. The analysis of the results obtained from both species of the site closer to the reactor indicated that the values of the DR in the operational stage did not change, compared with those in the preoperational stage previously analyzed. Therefore, the significant differences found between the monitored sites did not seem to be associated to the operation of the reactors.
