Daily Vaginal Dilator Use During Radiation for Women With Squamous Cell Carcinoma of the Anus: Vaginal Wall Dosimetry and Patient-Reported Sexual Function. Pract Radiat Oncol 2024; 14:e105-e116. [PMID: 37898354 DOI: 10.1016/j.prro.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/19/2023] [Accepted: 10/12/2023] [Indexed: 10/30/2023]
Abstract
PURPOSE At our institution, we treat patients with a daily vaginal dilator (VD) during chemoradiation (CRT) for squamous cell carcinoma of the anus (SCCA). We evaluated compliance with daily VD use, radiation dose to the vaginal wall (VW), and anterior vaginal wall (AVW), and patient-reported long-term sexual function. METHODS AND MATERIALS We included women with SCCA who received definitive, intensity-modulated radiation therapy-based CRT. Women who were alive without evidence of disease received a patient-reported outcome survey, which included the Female Sexual Function Index (FSFI). We identified factors associated with FSFI, such as radiation dose to the VW and AVW using linear regression models and used Youden index analysis to estimate a dose cutoff to predict sexual dysfunction. RESULTS Three hundred thirty-nine consecutively treated women were included in the analysis; 285 (84.1%) were treated with a daily VD. Of 184 women alive without disease, 90 patients (49%) completed the FSFI, and 51 (56.7%) were sexually active with valid FSFI scores. All received therapy with a daily VD. Forty-one women (80%) had sexual dysfunction. Univariate analysis showed higher dose to 50% (D50%) of the AVW correlated with worse FSFI (β -.262; P = .043), worse desire FSFI subscore (β -.056; P = .003), and worse pain FSFI subscore (β -.084; P = .009). Younger age correlated with worse pain FSFI subscale (β .067; P = .026). Age (β .070; P = .013) and AVW D50% (β -.087; P = .009) were significant on multivariable analysis. AVW D50% >48 Gy predicted increased risk of sexual dysfunction. CONCLUSIONS Daily VD use is safe and well tolerated during CRT for SCCA. Using a VD during treatment to displace the AVW may reduce the risk for sexual dysfunction. Limiting the AVW D50% <48 Gy may further reduce the risk but additional data are needed to validate this constraint.

Abstract
PURPOSE OF REVIEW This review provides evidence-based updates for the first-line management approaches for pelvic floor disorders in patients with gynecologic malignancies, as well as important provider considerations when referring for pelvic floor physical therapy. RECENT FINDINGS Currently, there is strong evidence to recommend pelvic floor muscle training as initial treatment for urinary incontinence and for pelvic organ prolapse; some evidence to recommend a more targeted pelvic floor muscle training program for fecal incontinence; and mostly expertise-based evidence to recommend vaginal gels or estrogen to aid with dyspareunia causing sexual dysfunction. More research is greatly needed to understand the role of overactive pelvic floor muscles in survivors with chronic pelvic pain and the treatment of post-radiation pelvic complications such as vaginal stenosis and cystitis. While pelvic floor disorders are common concerns in gynecologic cancer survivors, there are evidence-based initial noninvasive treatment approaches that can provide relief for many individuals.

Abstract
Objective To investigate the compliance and clinical efficacy of vaginal dilators (VDs) as an educational intervention in patients receiving pelvic radiation therapy (RT) for endometrial and cervical malignancies. Material and methods This is a single institution, retrospective chart review. Patients undergoing pelvic RT for endometrial or cervical cancer at our center were educated about the use of a VD starting 1 month after completion of RT. The patients were assessed after 3 months of prescribing VD. The demographic details and physical examination findings were extracted from medical records. Results We identified 54 female patients at our institution during the 6-month duration. The median mean age of patients was 54 ± 9.9 years. Twenty-four (44.4%) had endometrial cancers and 30 (55.6%) were diagnosed with cervical cancers. All patients received external beam RT, 38 (70.4%) received a dose of 45 Gy, and 16 (29.6%) patients received 50.4 Gy. Brachytherapy was also received by all patients, 28 (51.9%) received 5 Gy × 2 fractions, 4 (7.4%) received 7 Gy × 3 fractions and 22 (40.7%) received 8 Gy × 3 fractions. The compliance with VD use was 36 (66.6%) patients. Twenty-two (40.7%) used 2-3 times a week, 8 (14.8%) used <2 times per week and 6 (11.9%) used only once a month, and 18 (33.3%) did not use the VD post-treatment. Per vaginal (PV) examination findings of the patient's vagina with normal mucosa were evaluated in 32 (59.3%) and adhesions were found in 20 (37.0%) and 2 (3.7%) were unable to examine due to dense adhesions. During examination 12 (22.2%) had bleeding PV, however, the majority of the patients, 42 (77.8%) experienced no bleeding PV. Out of the 36 patients who used a VD, it was found to be efficacious in 29 (80.6%) of patients. Upon stratification of efficacy with a frequency of VD, 72.4% (n = 21) efficacy was seen in patients using frequent VD as prescribed 2-3 times per week. Conclusion The compliance and efficacy of VD use after radiation to pelvic in cervical and endometrial cancers at 3 months follow-up were found to be 66.6% and 80.6%, respectively. This shows that VD therapy is an effective interventional tool and patients should receive specialist education about vaginal stenosis as toxicity at the outset of treatment.

Patient reported improvement in sexual health outcomes following care in a sexual health clinic for women with cancer. Support Care Cancer 2023; 31:171. [PMID: 36795172 DOI: 10.1007/s00520-023-07635-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 02/05/2023] [Indexed: 02/17/2023]
Abstract
PURPOSE Sexual health concerns are common among female cancer survivors. Few data exist regarding patient-reported outcomes following interventions in this population. We aimed to determine patient-reported adherence and impact of interventions provided in an academic specialty clinic for treatment of sexual health problems. METHODS A cross-sectional quality improvement survey regarding sexual problems, adherence with recommended therapies, and improvement following intervention was administered to all women seen at the Women's Integrative Sexual Health (WISH) program at the University of Wisconsin-Madison between November 2013 and July 2019. Descriptive and Kruskal-Wallis tests were used to explore differences between groups. RESULTS Two hundred twenty women (median age at first visit = 50 years, 53.1% breast cancer) were identified; N =113 surveys were completed (response rate = 49.6%). The most common presenting complaints were pain with intercourse (87.2%), vaginal dryness (85.3%), and low libido (82.6%). Menopausal women were more likely than premenopausal women to present with vaginal dryness (93.4% vs. 69.7%, p = .001) and pain with intercourse (93.4% vs. 76.5%, p = .02). Nearly all women adhered to recommendations for vaginal moisturizers/lubricants (96.9-100%) and vibrating vaginal wands (82.4-92.3%). A majority found recommended interventions helpful regardless of menopausal status or cancer type and reported persistent improvement. Nearly all women had improvement in understanding sexual health (92%) and would recommend the WISH program to others (91%). CONCLUSION Women with cancer report integrative sexual health care to address sexual problems that are helpful and result in long-term improvement. Patients are overall highly adherent to recommended therapies, and nearly all would recommend the program to others. IMPLICATIONS FOR CANCER SURVIVORS Dedicated care to address sexual health in women after cancer treatment improves patient-reported sexual health outcomes across all cancer types.

Vaginal dilator use more than 9 months is a main prognostic factor for reducing G2‑late vaginal complications in 3D‑vaginal‑cuff brachytherapy (interventional radiotherapy)? Clin Transl Oncol 2023; 25:1748-1755. [PMID: 36752959 DOI: 10.1007/s12094-023-03099-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 12/31/2022] [Indexed: 02/09/2023]
Abstract
PURPOSE Analyse the impact of different prognostic factors on G2-late vaginal complications after vaginal brachytherapy (VBT) ± external beam radiotherapy (EBRT) in postoperative endometrial cancer (PEC). METHODS One hundred and twenty-six PEC patients treated with VBT ± EBRT were retrospectively analysed considering age, body mass index, applicator diameter, clinical target volume (CTV), use of dilators, chemotherapy and EQD2(α/β=3) at the most exposed 2 cm3 of the CTV as prognostic factors for vaginal complications. Late vaginal complications were evaluated using objective LENT-SOMA criteria. STATISTICS descriptive analysis, Chi-square, Fisher and Student tests were applied. Univariate and multivariate analyses were performed with the Baptista-Pike exact method and multiple logistic regression. RESULTS Mean age was 65 years (SD ± 10), and median follow-up was 66 months (8-104). 19/126 patients (15%) showed G2-late vaginal complications, and 107/126 (85%) G0-G1. Univariate analysis showed: CTV ≤ 9 cm3 (p = 0.036), use of dilators < 9 months (p = 0.015), and total ≥ 68 Gy EQD2 received by 2 cm3 of CTV (p = 0.039) were associated with G2-late vaginal toxicity. Multivariate analysis showed the use of dilators < 9 months as an independent prognostic factor for G2-late vaginal toxicity (p = 0.043, OR 8.59, CI 1.59-159.9). CONCLUSION The use of dilators < 9 months in VBT ± EBRT for PEC was an independent prognostic factor for G2-late vaginal toxicity. The use of vaginal dilators ≥ 9 months requires further analysis in studies evaluating late vaginal toxicity.

Preliminary results of a vaginal constraint for reducing G2 late vaginal complications after postoperative brachytherapy in endometrial cancer: a prospective analysis. Clin Transl Oncol 2021; 24:875-881. [PMID: 34854030 PMCID: PMC9013320 DOI: 10.1007/s12094-021-02737-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 11/17/2021] [Indexed: 11/15/2022]
Abstract
Purpose To evaluate the preliminary results of the use of 68 Gy EQD2(α/β=3 Gy) as a dose limit to the lowest dose in the most exposed 2 cm3 of the vagina in order to reduce G2 late vaginal problems in postoperative endometrial carcinoma (EC).
Methods From November 2016 to October 2019, 69 postoperative EC patients receiving vaginal brachytherapy (VBT) ± external beam radiotherapy (EBRT) were prospectively analyzed. The median EBRT dose was 45 Gy (range: 44–50.4 Gy), 1.8−2 Gy/day, 5 fractions(Fr)/week. VBT was administered with the following schedule: 1Fr of 7 Gy after EBRT and 2 daily Fr × 7.5 Gy in exclusive VBT. The dose was prescribed at 0.5 cm from the applicator surface with an active length of 2.5 cm; 56 patients were treated with vaginal cylinders (49–3.5 cm, 6–3 cm, and 1–2.5 cm) and 13 with the colpostat technique. The overall VBT dose was adjusted to meet the vaginal restriction of < 68 Gy EQD2(α/β=3 Gy) at 2 cm3. Late toxicity was prospectively assessed using RTOG scores for bladder and rectum, and the objective LENT-SOMA criteria for vagina.
Results With a median follow-up of 31.0 months, no vaginal-cuff recurrences were found. Late toxicity: only 1G1(1.4%) rectal toxicity; 21G1(30.4%) and 3G2(4.3%) vaginal complications. Only one (1.4%) of 3 G2 manifested as vaginal shortening.
Conclusions In postoperative EC patients treated with VBT, only one developed G2 vaginal stenosis with the use of 68 Gy EQD2(α/β=3 Gy) as a dose constraint. These preliminary results seem to indicate the value of this dose limit for reducing G2 vaginal stenosis. Nonetheless, these findings should be confirmed in a larger number of patients with longer follow-up.

Abstract
OBJECTIVE In women with cervical cancer (CC), treatment with radiation causes changes in vaginal biomechanical properties, anatomy and function. The aims of the current study were to objectively assess effects of radiotherapy (RT) on vaginal elasticity, wall mobility and contraction strength; and to evaluate associations of these changes with sexual function. STUDY DESIGN This prospective cohort study was approved by our Institutional Review Board. Between May 2018 and June 2020, women with CC who were candidates for RT were eligible to participate. Participants underwent vaginal tactile imaging (VTI) evaluation and were asked to fill the Female Sexual Function Index (FSFI) questionnaire at the time of first RT session and at a 6-month post-treatment follow up visit. Women who underwent radical hysterectomy, or had pelvic side-wall, pelvic or distant organ metastasis were not included. RESULTS A total of 25 women with locally advanced CC were included in the final analysis. The mean age was 39 ± 2.7 years, the mean BMI was 24.8 ± 2.2 kg/m2 and the median parity was 2 (range: 1-5). Following RT, the mean scores for vaginal elasticity and vaginal tightening were significantly lower than at pre-treatment: 11.3 ± 2.5 vs. 28.3 ± 9, P < 0.0001 and 2.6 ± 0.7 vs. 16.7 ± 3, P < 0.0001, respectively. Following RT, significant decreases were demonstrated in vaginal wall mobility and pelvic muscle contraction strength: from 1.77 ± 0.34 to 0.36 ± 0.15, P < 0.0001 and from 2.55 ± 0.48 to 0.52 ± 0.23, P < 0.0001, respectively. Compared to pre-treatment, post-RT vaginal length was significantly shorter (3.30 ± 0.22 vs. 7.64 ± 0.63, P = 0.0023) and sexual intercourse frequency significantly lower: 1 (range 1-2) vs. 2 (range 1-4), P = 0.014). The mean total FSFI score was significantly lower following RT (6.7 ± 1 vs. 14.5 ± 2.7, P < 0.0001). CONCLUSIONS Women with locally advanced CC who have been treated with RT exhibit persistent vaginal biomechanical changes that compromise sexual activity and result in considerable distress.

Abstract
OBJECTIVE The objective of this study was to examine patterns of care and outcomes of female cancer patients treated for sexual and menopausal symptoms following pelvic radiotherapy (PRT) at our institution's multidisciplinary Sexuality, Intimacy, and Menopause (SIMS) Program. MATERIALS AND METHODS We performed a retrospective review of 69 female patients who received PRT for gynecologic or gastrointestinal malignancies and were referred for SIMS Program intervention. Indications for referral and treatment patterns were summarized. Preintervention and postintervention, patients were screened at follow-up visits, and symptoms were recorded. Statistics were performed using Stata 13.1. RESULTS Cancer types included cervical (53.6%), endometrial (31.9%), anorectal (5.8%), and vulvar/vaginal (8.7%). The median age was 48 years (interquartile range: 38 to 58 y). Patients were educated on vaginal lubricants, moisturizers, and dilator therapy both before and after PRT. Reasons for SIMS referral included persistent menopausal symptoms (50.7%), dyspareunia (40.6%), vaginal dryness (37.7%), decreased libido (17.4%), intimacy concerns (17.4%), and/or physical examination alterations (27.5%). SIMS interventions included vaginal estrogen (77.3%), nonhormonal climacteric interventions (53%), systemic hormone therapy (31.8%), dehydroepiandrosterone (4.6%), testosterone cream (4.6%), and/or psychological pharmacotherapy or counseling (13.6%). With a median follow-up of 36 months (interquartile range: 18 to 58 mo), sexual symptoms improved or were stable in 83.6%, while menopausal symptoms improved or were stable in 80.5%. CONCLUSIONS This study highlights the importance of multidisciplinary care in improving the sexual and menopausal symptoms of women after PRT. Future work examining the impact of intervention timing with respect to PRT and measures of patient satisfaction is warranted.

Vaginal stenosis in women with cervical or endometrial cancer after pelvic radiotherapy: a cross-sectional study of vaginal measurements, risk for sexual dysfunction and quality of life. Int Urogynecol J 2021; 33:637-649. [PMID: 33891152 DOI: 10.1007/s00192-021-04798-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Accepted: 04/09/2021] [Indexed: 12/24/2022]
Abstract
INTRODUCTION AND HYPOTHESIS Radiotherapy (RT) for cervical (CC) and endometrial cancer (EC) is known to lead to vaginal stenosis (VS), but the comparison between vaginal anatomical measurements and the risk of sexual dysfunction presents a wide variety of results among the literature. Thus, we sought to assess the prevalence of VS, vaginal measurements, sexual dysfunction and QOL in women with CC and EC submitted to pelvic RT with or without previous surgery. METHODS Cross-sectional study that included 61 women with CC and 69 with EC. VS was classified by the Common Terminology Criteria for Adverse Effects version 5.0 (CTCAE v5.0), sexual function by the validated Female Sexual Function Index (FSFI) and QOL by the validated World Health Organization questionnaire (WHOQOL-BREF). Acrylic cylinders were used for vaginal measurements. Uni-/multivariate analyses to address factors associated with VC in both groups were performed. RESULTS The prevalence of VS was 79% and 67% within patients with CC and EC, respectively. Vagina length was decreased in both groups without statistical difference (7.2 ± 1.7 vs. 6.6 ± 1.8;p = 0.072). Vaginal diameter was significantly higher (p = 0.047) in women with EC (25.4 ± 6.3) than in those with CC (23.1 ± 5.7). Sexual dysfunction was highly prevalent for both CC and EC (88% vs. 91%; p = 0.598). There was no difference in all WHOQOL-BREF domains between women with CC and EC. CONCLUSIONS VS is highly prevalent in CC and EC patients, with vaginal length decreased in both groups but with a higher vaginal diameter in those with EC. Nevertheless, sexual dysfunction is highly prevalent in both groups.

Abstract
Radiation-induced vaginal stenosis (VS) is a common side effect of pelvic radiotherapy (RT). RT-induced VS may have various negative effects on women’s quality of life, in particular dyspareunia, decreased vaginal lubrication and difficulties in sexual intercourse. This narrative review provides the aspects of RT-induced VS pathogenesis, incidence, evaluation and associated risk factors. Available treatment modalities are discussed in the article, putting the focus on preliminary, although promising, experience in the use of hyaluronic acid and laser therapy in cancer survivors after pelvic RT.

Diagnostic Methods for Vaginal Stenosis and Compliance to Vaginal Dilator Use: A Systematic Review. J Sex Med 2021; 18:493-514. [PMID: 33526400 DOI: 10.1016/j.jsxm.2020.12.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 12/10/2020] [Accepted: 12/25/2020] [Indexed: 01/22/2023]
Abstract
BACKGROUND Vaginal stenosis (VS) is a common side effect of pelvic radiotherapy for gynecological cancer in women. It has a high incidence variability, likely due to unstandardized and subjective assessment methods. Furthermore, even though the worldwide standard treatment for VS is vaginal dilation, low compliance rates have been noted. AIM To evaluate the parameters used to diagnose VS and to assess whether the lack of an objective measure of VS hampers vaginal dilator use. METHODS A systematic review in accordance with the PRISMA reporting guidelines was conducted. PubMed, EMBASE, and Web of Science databases were searched. Randomized trials and prospective, retrospective, and cross-sectional studies published from January 2011 to February 2020 were included. OUTCOMES The main outcome of this study was a review of the published literature on assessment methods for VS and compliance to vaginal dilator use. RESULTS Of the 28 articles obtained, only 7 used objective methods to measure the vaginal volume. 3 studies have demonstrated patient's concern with VS development and showed a high compliance to dilator use, whereas others reported several barriers to dilator use. CLINICAL IMPLICATIONS Lack of an objective assessment method can be a predisposing factor for uncertain VS incidence rates and impair compliance to vaginal dilator therapy, leading to long-term VS and sexual dysfunction. STRENGTHS & LIMITATIONS This is the first systematic review on the heterogeneity of VS evaluation methods and compliance to vaginal dilator use. All studies were comprehensively evaluated by 2 reviewers. The limitations included the heterogeneity of the study designs and the unstandardized criteria used to classify stenosis or to evaluate compliance to dilator use. Although 3 well-known databases were used, the inclusion of more data sources could have increased the number of publications included in this review. CONCLUSION VS is frequently diagnosed using subjective parameters. Few unstandardized objective methods are used to evaluate this condition. Regarding compliance to vaginal dilator use, there was a high dropout rate during follow-up and no consensus on starting time or ideal usage. Haddad NC, Soares Brollo LC, Pinho Oliveira MA, et al.

Assessment of an onco-sexology support and follow-up program in cervical or vaginal cancer patients undergoing brachytherapy. Support Care Cancer 2021; 29:4311-4318. [PMID: 33411047 DOI: 10.1007/s00520-020-05898-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 11/16/2020] [Indexed: 11/27/2022]
Abstract
PURPOSE Women's sexual health and wellbeing with cervical or vaginal cancer may be largely affected by complications from external beam radiotherapy (EBRT) and utero-vaginal brachytherapy (BT), of which vaginal stenosis is the main complication. The objective of this study was to assess the impact of support by a nurse sexologist on sexuality, vaginal side-effects, and the quality of clinical follow-up in patients treated with brachytherapy for cervical or vaginal cancer. METHODS We performed a retrospective study of the sexuality of women treated for cervical or vaginal cancer. Data from patients with cervical or vaginal cancer who underwent brachytherapy between 2013 and 2017 were collected at Institut Universitaire de Cancer de Toulouse-Oncopôle (IUCT-Oncopôle). Patients were divided into two groups: group A (intervention group) received support from a nurse sexologist and group B (control group) did not. The chi-square test and a logistic multivariate model were used for data analysis. RESULTS A total of 156 patients were included in this study, including 57.7% who were followed by a nurse sexologist. We observed low compliance in using vaginal dilators after brachytherapy and/or radiotherapy over time regardless of the group, and patients' sexual activity was inadequately addressed. Information regarding the resumption of sexuality 2 months after treatment was missing in 1.1% of patients in group A and in 36.4% of patients in group B. Multivariate analysis showed that patients in group A had a lower risk of developing vaginal stenosis with OR crude = 0.5 (95% CI = 0.25-0.92) and OR adj. = 0.5 (95% CI = 0.26-1.09) compared with those in group B. CONCLUSION This retrospective study highlights the lack of information collected by physicians during follow-up concerning the sexuality of patients with cervical or vaginal cancer treated by EBRT and BT. The support offered by nurse sexologists in improving patients' sexual activity and reducing their physical side-effects such as vaginal stenosis is likely to be beneficial. A prospective study is currently being conducted to validate the present findings.

EQD2 Analyses of Vaginal Complications in Exclusive Brachytherapy for Postoperative Endometrial Carcinoma. Cancers (Basel) 2020; 12:cancers12103059. [PMID: 33092163 PMCID: PMC7589275 DOI: 10.3390/cancers12103059] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 10/08/2020] [Accepted: 10/16/2020] [Indexed: 11/28/2022] Open
Abstract
Simple Summary Vaginal complications in exclusive vaginal-cuff brachytherapy (EVCBT) have not been analyzed in terms of the dose received by a vaginal volume of 2 cm3. The aim of this work was to analyze the vaginal dose and complications in EVCBT. In the present analysis, we found that all the patients receiving < 68Gy equivalent dose 2Gy/day at 2 cm3 of the most exposed area to the dose of the vagina only developed G0–G1 and 1G2 without vaginal stenosis complications and without relapses. This dose limit could eliminate G2 vaginal stenosis and is the hypothesis of a new analysis in our center. Abstract Background: To evaluate whether EQD2(α/β = 3Gy) at 2 cm3 of the most exposed area of the vagina is related to late vaginal toxicity in postoperative endometrial cancer (PEC) patients (p) treated with exclusive brachytherapy (BT). Methods: From 2014 to 2017, 43p were included in this study. BT was administered: 3-fractions of 6Gy in 37p and 2-fractions of 7.5Gy in 6p. The dose was prescribed at a depth of 5 mm from the applicator surface with dose-point optimization based on distance. The active treatment length was 2.5 cm. CTV-D90 and the dose to the most exposed 2 cm3 of the vagina was calculated for each patient. Late toxicity of the bladder and rectum was assessed using Radiation Therapy Oncology Group (RTOG) criteria, and vaginal toxicity by objective Late Effects Normal Tissue Task Force (LENT)-Subjective, Objective, Management, Analytic (SOMA) (LENT-SOMA) criteria. Statistics: frequency tables, mean, median, range, standard deviation, and box plot. Results: The median follow-up was 51 months (12–68). 20 p (46.5%) and 2 p (4.7%) developed G1 and G2 vaginal complications, respectively. Only 1/2 p-G2 receiving EQD2(α/β = 3Gy) at 2 cm3 >68Gy presented vaginal shortening and 18/20 p-G1 received doses < 68Gy. Conclusions: PECp receiving exclusive brachytherapy with doses < 68Gy EQD2(α/β = 3Gy) at 2 cm2 of the vagina presented only G0–G1 vaginal toxicity, except for one with bleeding telangiectasias. Larger prospective studies are necessary to confirm the present results.

Abstract
PURPOSE Successful multimodality treatment of anorectal cancers has led to increased numbers of survivors who experience permanent, life-changing side effects of treatment. Little is known about sexual dysfunction (SD) in this population. The etiology of SD after anorectal cancer treatment is complex and multifactorial. However, pelvic radiation plays a significant negative role in anatomic, hormonal, and physiological aspects of sexual function. METHODS AND MATERIALS A systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. Information was organized by key concepts useful for patient education, including (1) rates of SD after pelvic radiation for rectal cancer, (2) rates of SD after pelvic radiation for anal cancer, (3) mechanisms of SD and methods to reduce rates of SD, and (4) issues and opportunities related to patient education and discussion of SD after pelvic radiation. RESULTS SD after pelvic radiation for anorectal cancers is common in both men and women. Higher radiation doses may increase the risk for vaginal stenosis; however, it is unclear whether there are similar dose-volume relationships for men. Vaginal dilators and advanced radiation techniques can reduce the radiation dose to sexual organs at risk. Improvement is needed regarding counseling and education of patients about SD. CONCLUSIONS This review provides information from previously published studies that clinicians may use in their discussions with patients embarking on pelvic radiation for anorectal cancers. More modern, standardized, and complete data are needed to quantify the risk of SD after treatment. Some methods of sexual toxicity reduction have been studied, but further study into interventions aimed at treating postradiation sexual function are needed.

Abstract
This clinical report aimed to evaluate the effectiveness of the combination of vaginal dilator (VD) and pelvic floor muscle exercises (PFME) on vaginal stenosis, sexual health and quality of life among women undergoing radiotherapy treatment for cervical cancer; PFME were instructed prior to radiotherapy with six-month follow-up. An intention-to-treat analysis was performed for the 28 women. At four-months after radiotherapy, most of the women (90.9%) maintained/increased one size of the VD and were sexually active (81.8%). Adherence to VD was high. Regarding quality of life, there was more limitation in emotional functioning. VD and PFME were effective at preventing stenosis.

Abstract
The female reproductive tract (FRT), similar to other mucosal sites, harbours a site-specific microbiome, which has an essential role in maintaining health and homeostasis. In the majority of women of reproductive age, the microbiota of the lower FRT (vagina and cervix) microenvironment is dominated by Lactobacillus species, which benefit the host through symbiotic relationships. By contrast, the upper FRT (uterus, Fallopian tubes and ovaries) might be sterile in healthy individuals or contain a low-biomass microbiome with a diverse mixture of microorganisms. When dysbiosis occurs, altered immune and metabolic signalling can affect hallmarks of cancer, including chronic inflammation, epithelial barrier breach, changes in cellular proliferation and apoptosis, genome instability, angiogenesis and metabolic dysregulation. These pathophysiological changes might lead to gynaecological cancer. Emerging evidence shows that genital dysbiosis and/or specific bacteria might have an active role in the development and/or progression and metastasis of gynaecological malignancies, such as cervical, endometrial and ovarian cancers, through direct and indirect mechanisms, including modulation of oestrogen metabolism. Cancer therapies might also alter microbiota at sites throughout the body. Reciprocally, microbiota composition can influence the efficacy and toxic effects of cancer therapies, as well as quality of life following cancer treatment. Modulation of the microbiome via probiotics or microbiota transplant might prove useful in improving responsiveness to cancer treatment and quality of life. Elucidating these complex host-microbiome interactions, including the crosstalk between distal and local sites, will translate into interventions for prevention, therapeutic efficacy and toxic effects to enhance health outcomes for women with gynaecological cancers.

Abstract
PURPOSE Guidelines for the care of women undergoing pelvic radiation therapy (RT) recommend vaginal dilator therapy (VDT) to prevent radiation-induced vaginal stenosis (VS); however, no standard protocol exists. This review seeks to update our current state of knowledge concerning VS and VDT in radiation oncology. METHODS AND MATERIALS A comprehensive literature review (1972-2017) was conducted using search terms "vaginal stenosis," "radiation," and "vaginal dilator." Information was organized by key concepts including VS definition, time course, pathophysiology, risk factors, and interventions. RESULTS VS is a well-described consequence of pelvic RT, with early manifestations and late changes evolving over several years. Strong risk factors for VS include RT dose and volume of vagina irradiated. Resultant vaginal changes can interfere with sexual function and correlational studies support the use of preventive VDT. The complexity of factors that drive noncompliance with VDT is well recognized. There are no prospective data to guide optimal duration of VDT, and the consistency with which radiation oncologists monitor VS and manage its consequences is unknown. CONCLUSIONS This review provides information concerning VS definition, pathophysiology, and risk factors and identifies domains of VDT practice that are understudied. Prospective efforts to monitor and measure outcomes of patients who are prescribed VDT are needed to guide practice.
