e17020 Background: Treatment options for cervical cancer include surgery, radiation therapy, chemotherapy, and immunotherapy depending upon the disease stage. There is limited real-world evidence providing us with a clinical profile for a treated cervical cancer patient. The objective of this study was to compare cervical cancer patients who were currently receiving treatment versus those not receiving treatment. Methods: This was a retrospective, cross-sectional analysis of Medical Expenditure Panel Survey (MEPS) data (2006-2015). Cervical cancer cases were identified using ICD-9 CM code 180 or clinical classification software code 26. Patients receiving only chemotherapy, radiation therapy, undergoing surgery, or a combination of these treatments in a given year were regarded as “currently receiving treatment”. The comparator cohort included patients “not currently receiving treatment”. The two cohorts were compared in terms of patient clinical characteristics using bivariate analyses. Results: The analytic cohort consisted of 275,246 cervical cancer cases (mean age: 42 years, Caucasian: 88.0%, having private insurance: 55.3%) of which 115,639 (42.01%) were “currently receiving treatment”. The most common treatment option was undergoing surgery only (88.21%), followed by combination therapy (6.82%), chemotherapy only (3.84%), and radiation therapy only (1.12%). The “currently receiving treatment” cohort had a significantly higher proportion of patients having a history of myocardial infarction (4.21% vs 3.50%), congestive heart failure (2.73% vs 1.42%), chronic obstructive pulmonary disorder (29.5% vs 23.2%), connective tissue disease (20.5% vs 11.6%), renal disease (2.49% vs 0.48%), and diabetes (17.7% vs 11.7%) compared to those “not currently receiving treatment”. The latter cohort had a higher proportion of patients with moderate/severe liver disease (0.46% vs 5.32%). Conclusions: The observed real-world patient characteristics and treatment patterns were indicative of a cohort of largely early stage cervical cancer patients. Patients receiving treatment appeared to have a higher comorbidity burden which may subsequently result in poorer quality of life and activity limitations.

e18019 Background: To address the gap in US-based real-world data, this analysis described the real-world treatment patterns among newly diagnosed cervical cancer patients. Methods: Women newly diagnosed with cervical cancer between Jan 2015 – June 2018, with a confirmatory diagnosis or treatment within 2 months, and continuous enrollment for 12 months prior and 6 months post diagnosis were identified in the Optum Clinformatics DataMart database. Surgeries (hysterectomy, conization, lymphadenectomy and trachelectomy), radiation (external beam radiotherapy [EBRT]/brachytherapy) and systemic therapies (chemotherapy/immunotherapy) received after diagnosis were described by line of therapy (LOT). The start of the first LOT was the date of the first treatment. All treatments initiated within 90 days of a surgery or the end of radiotherapy, and all systemic treatment started within 28 days of any previous treatment were a part of the same LOT. Most frequently received treatments in LOT1 and 2 and time to treatment initiation were described. Results: Out of 1,004 newly diagnosed women, 655 (65.2%) received at least LOT1 and 162 (16.14%) received LOT2. Median time to first LOT was 1.5 (1.4 – 1.7) months from diagnosis. Surgery was the most common treatment in LOT1 (58.0%). Among patients receiving radiation, the majority received a combination of EBRT and brachytherapy (LOT1: 66.9%, LOT2: 58.0%). The use of chemotherapy increased with subsequent LOTs (LOT1: 53.3%, LOT2: 61.1%). Treatments received in LOT1 and LOT2 are described in the table. Conclusions: This analysis shows that newly diagnosed cervical cancer patients are primarily receiving guideline recommended treatment with surgery or chemoradiation as primary treatment. Radiation therapy includes EBRT and brachytherapy. Counts ≤ 10 are not reported (NR). [Table: see text]

AbstractDiversity of the gut microbiome is associated with higher response rates for cancer patients receiving immunotherapy but has not been investigated in patients receiving radiation therapy. Additionally, current studies investigating the gut microbiome and outcomes in cancer patients may not have adjusted for established risk factors. Here, we sought to determine if diversity and composition of the gut microbiome was independently associated with survival in cervical cancer patients receiving chemoradiation. Our study demonstrates that the diversity of gut microbiota is associated with a favorable response to chemoradiation. Additionally, compositional variation among patients correlated with short term and long-term survival. Short term survivor fecal samples were significantly enriched in Porphyromonas, Porphyromonadaceae, and Dialister, whereas long term survivor samples were significantly enriched in Escherichia Shigella, Enterobacteriaceae, and Enterobacteriales. Moreover, analysis of immune cells from cervical tumor brush samples by flow cytometry revealed that patients with a high microbiome diversity had increased tumor infiltration of CD4+ lymphocytes as well as activated subsets of CD4 cells expressing ki67+ and CD69+ over the course of radiation therapy. Modulation of the gut microbiota before chemoradiation might provide an alternative way to enhance treatment efficacy and improve treatment outcomes in cervical cancer patients.

Abstract Purpose Fractures are known to shorten life expectancy and worsen the quality of life. The risk of fractures after radiation therapy in cervical cancer patients is known to be multifactorial. In this study, we examined risk factors for fractures in cervical cancer patients, especially by evaluating bone densities and DVH parameters for fractured bones. Materials and Methods For 42 patients, clinical characteristics, pretreatment CT bone densities, and radiation dose were compared between patients with and without fractures. Results Posttreatment fractures occurred in 25 bones among ten patients. Pretreatment CT bone densities were significantly lower in patients with fractures (P < 0.05–0.01 across sites, except for the ilium and the ischium). Although DVH parameters were also significantly associated with fractures in univariate analysis, only CT densities were significantly associated with fractures in multivariate analysis. Conclusion Pretreatment CT densities of spinal and pelvic bones, which may reflect osteoporosis, have a significant impact on the risk for posttreatment fractures.

ObjectiveConventional radical hysterectomy with pelvic lymphadenectomy (RHL) for early-stage cervical cancer is associated with significant bladder, anorectal, and sexual dysfunction. Nerve-sparing modification of RHL (NS-RHL) has been developed with the aim to reduce surgical treatment-related morbidity. Postoperative radiation therapy (RT) is offered to patients with unfavorable prognostic features to improve local control. The aim of the study was to assess self-reported morbidity of various types of treatment in cervical cancer patients.MethodsSelf-reported symptoms were prospectively assessed before and 1 and 2 years after treatment by the Dutch Gynaecologic Leiden Questionnaire.ResultsIncluded were 229 women (123 NS-RHL and 106 conventional RHL). Ninety-four (41%) received RT. Up to 2 years (response rate, 81%), women reported significantly more bowel, bladder, and sexual symptoms compared with the pretreatment situation. No significant difference was found between the conventional RHL and NS-RHL with the exception of the unexpected finding that a smaller percentage in the NS-RHL group (34% vs 68%) complained about numbness of the labia and/ or thigh. Radiation therapy had a negative impact on diarrhea, urine incontinence, lymphedema, and sexual symptoms (especially a narrow/short vagina).ConclusionsIn the current longitudinal cohort study, treatment for early-stage cervical cancer was associated with worse subjective bladder, anorectal, and sexual functioning, irrespective of the surgical procedure used. Postoperative RT resulted in a significant deterioration of these functions. The results have to be interpreted with caution in view of the study design and method used.
