Quality of life and adverse events after radiotherapy in gynecologic cancer survivors: a cohort study

Survivorship research in advanced gynecological cancer: A scoping review of cohort studies

BACKGROUND

Recent calls to action highlight the need to address gaps in our understanding of survivorship for those living with advanced gynecological cancer to support optimal care. To ensure future research fills these knowledge gaps, we need to understand the breadth of existing survivorship research in this patient group, including the outcomes assessed, the populations included and the duration and retention in follow-up.

METHODS

We conducted a systematic scoping review searching PubMed, PsychINFO, and CINAHL during the month of November 2022 to identify prospective cohort studies measuring survivorship outcomes among participants with advanced (stage III-IV) gynecological cancer, or in cohorts in which ≥50% of participants had advanced cancer, or which provide results separately for patients with advanced cancer. Articles were screened, and data extracted using a standard form.

RESULTS

We assessed 33 articles from 21 unique studies, which overall included 6023 participants with gynecological cancer. Of these, 45% had cervical cancer, 44% ovarian, 10% endometrial/uterine, and 1% vaginal/vulvar cancer. The most frequently measured survivorship outcome was quality of life. Of the 33 articles, most reported on participant age (n = 31), but relatively few reported on comorbidities (n = 10), physical status (n = 6), ethnic background (n = 4), the country of birth (n = 2), or the area of participant residence (n = 2). None included details on indigenous status. Recruitment proportions ranged from 48% to 100%. Retention proportions ranged from 15% to 97%.

CONCLUSION

Our findings highlight gaps in survivorship research for advanced gynecological cancers and emphasize the need for future studies to include and describe the experiences of diverse and underrepresented groups.

Sexual Dysfunction in Cervical Cancer Survivors: A Scoping Review

Sexual function in cervical cancer survivors declines significantly after treatments irrespective of the modality used. Only a few studies have looked at their psychosexual needs, perception, and acceptance of psychosexual support. This review summarizes findings of current qualitative as well as quantitative studies to understand the plight of cervical cancer survivors regarding sexual dysfunction and the management issues. The effect of gynecologic cancers on sexuality depends on multiple factors such as psychosexual factors, biologic factors, and age. Younger patients have poorer outcomes with a more pronounced impact on sexual well-being. Radicality of surgery has direct correlation with sexual dysfunction. Low or no sexual interest, lack of lubrication, dyspareunia, and reduced vaginal caliber are frequently found. For too long, researchers have focused on defining the prevalence and types of sexual problems after various cancer treatments. The area that continues to be neglected is the evaluation of effective interventions to prevent or treat cancer-related sexual dysfunction. In particular, mental health and medical specialists need to collaborate to create cost-effective treatment programs. Collaborative intervention with gynecologists, sexologists, radiotherapists, and nursing staff would be beneficial to optimize the sexual wellness of cancer survivors and their spouses.

Healing effects of a protein scaffold loaded with adipose-derived mesenchymal stem cells on radiation-induced vaginal injury in rats

Objectives

Cervical cancer, the most common female cancer after breast cancer, is typically treated using radiotherapy. However, pelvic radiotherapy can cause irreversible damage to the vagina, seriously affecting patients’ quality of life. In this study, protein scaffolds loaded with rat adipose-derived mesenchymal stem cells (ADSCs) were implanted into irradiated tissue to assess their healing potential.

Methods

We established a rat model of radiation-induced vaginal injury. Complexes (consisting of protein scaffolds loaded with ADSCs) were implanted into injury sites. Histological analysis were used to assess regeneration of the vaginal epithelium. RNA sequencing was used to study the therapeutic mechanism of the complexes.

Results

The complexes promoted vaginal epithelial cell regeneration, vaginal tissue repair and improved vaginal stenosis and contracture. Compared with rats transplanted with ADSCs, rats transplanted with complexes achieved better therapeutic effects.

Conclusions

Protein scaffold-ADSC complexes had a beneficial therapeutic effect on radiation-induced vaginal injury in rats and may serve as the basis of a novel therapeutic approach for radiation dermatitis.

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

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.

Factors of sexual quality of life in gynaecological cancers: a systematic literature review

Background

The impact of cancer diagnosis and treatment on sexual quality of life (SQoL) is a well-established survivorship issue for gynaecological cancer survivors (GCS), yet little is known on how to intervene.

Purpose

The aim of this systematic review was to identify the factors explaining the variability in SQoL for GCS.

Methods

We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework and the software Covidence. Electronic databases Scopus, Web of Science, PUBMED and CINAHL were searched for original research on GCS published between 2002 and 2018. We performed a two-stage screening process against selection criteria and quality assessment of individual studies. The Salutogenic Theory and the PRECEDE–PROCEED model were used as theoretical frameworks to identify and categorise factors.

Results

The initial search yielded 3,505 articles resulting in a total of 46 studies used to examine the association between factors of SQoL and gynaecological cancers. Our findings suggested that SQoL varies across subgroups based on age, menopausal status, relationship status, and treatment modality. Protective factors included clinicians’ knowledge and confidence, preventive medical approach, risk and needs assessment, patient–clinician communication, relationship quality, psychosocial support, symptom management, accessibility of psychosexual care, and self-efficacy in the rediscovery of sexuality.

Conclusion

Despite the high incidence and long-term impact of sexual health issues on quality of life, supportive care needs are not being met. A better understanding of the evidence base around the factors of SQoL can help health professionals take steps to protect and improve SQoL in GCS.

Pelvic floor muscle assessment by digital palpation and translabial ultrasound of women with cervical or endometrial cancer after pelvic radiotherapy: a cross-sectional study

INTRODUCTION AND HYPOTHESIS

We hypothesized that anatomical changes in the pelvic floor muscles (PFM) could be detected using four-dimensional translabial ultrasound (4D TLUS) in patients with cervical (CC) or endometrial cancer (EC) who underwent pelvic radiotherapy (RT) as digital palpation may present sensitivity limitations.

METHODS

This was a cross-sectional study that included 64 women (26 with CC and 38 with EC). PFM function was assessed by digital palpation, grading muscle strength according to the Modified Oxford Scale and by 4D TLUS. Ultrasonographic variables were: levator plate angle, hiatal area, puborectalis muscle thickness, puborectalis strain and levator ani muscle integrity. These variables were also correlated with clinical and sociodemographic data from all these patients. A 5% significance level was adopted.

RESULTS

When assessed by digital palpation, no significant difference was found in PFM strength between women with CC and those with EC (p = 0.747). However, when assessed by 4D TLUS, women with CC presented greater thickening of the left (p = 0.039) and right (p = 0.014) lower portion of the puborectalis muscle during PFM contraction compared to those with EC. After pooling the groups, higher cancer staging (p = 0.028) was associated with smaller narrowing in the symphysis-levator distance, and shorter RT finishing duration (< 60 months) was associated with higher thickening in the left (p = 0.029) and right (p = 0.013) upper portion of the puborectalis muscle during PFM contraction as well as a shorter menopause duration (p = 0.007 and p = 0.002, respectively).

CONCLUSIONS

Anatomical changes in the puborectalis muscle during PFM contraction were detected by 4D TLUS within gynecological cancer patients after pelvic RT.

Health Services, Socioeconomic Indicators, and Primary Care Coverage in Mortality by Lower Genital Tract and Breast Neoplasias in Brazilian Women during Reproductive and Non-Reproductive Periods

Women's health assistance at the low-complexity level is focused on the most common diseases and can be affected by primary health care coverage, particularly in areas far away from large urban centers. Thus, in this work, we aim to analyze the relationship between socioeconomic status, health care indicators, and primary care coverage in mortality from neoplasms of the lower genital tract and breast in Brazilian women during reproductive and non-reproductive periods. We conducted an ecological study at the Gynecology Discipline, Medicine School, University of São Paulo. Secondary data were collected from women according to reproductive periods and mortality data from the Mortality Information System based on International Classification of Disease-10th edition regarding breast and lower genital tract neoplasms in 2017. The health service and socioeconomic indicators were obtained from the Informatics Department of the Unified Health System and Brazilian Institute of Geography and Statistics. Our results showed that primary care coverage and health service indicators were not associated with mortality from breast cancer and the female lower genital tract, both in reproductive and non-reproductive periods. Sociodemographic indicators were found to be associated with mortality from breast cancer and the female lower genital tract, with income being associated with reproductive period (β = -0.4; 95% CI, -0.8 to -0.03) and educational level in the non-reproductive period (β = 9.7; 95% CI, 1.5 to 18.0).

Factors associated with changes in vaginal length and diameter during pelvic radiotherapy for cervical cancer

OBJECTIVES

This study reports the incidence and factors associated with vaginal stenosis and changes in vaginal dimensions after pelvic radiotherapy for cervical cancer.

METHODS

A descriptive longitudinal study with 139 women with cervical cancer was conducted from January 2013 to November 2015. The outcome variables were vaginal stenosis assessed using the Common Terminology Criteria for Adverse Events (CTCAE v3.0) and changes in vaginal diameter and length after the end of radiotherapy. Independent variables were the characteristics of the neoplasm, clinical and sociodemographic data. Bivariate analysis was carried out using χ ², Kruskal-Wallis and Mann-Whitney's test. Multiple analysis was carried out using Poisson regression and a generalized linear model.

RESULTS

Most women (50.4%) had stage IIIB tumors. According to CTCAE v3.0 scale, 30.2% had no stenosis, 69.1% had grade 1 and 0.7% had grade 2 stenosis after radiotherapy. Regarding changes in vaginal measures, the mean variation in diameter was - 0.6 (± 1.7) mm and the mean variation in length was - 0.6 (± 1.3) cm. In the final statistical model, having tumoral invasion of the vaginal walls (coefficient + 0.73, p < 0.01) and diabetes (coefficient + 1.16; p < 0.01) were associated with lower vaginal stenosis and lower reduction of vaginal dimensions. Advanced clinical stage (coefficient + 1.44; p = 0.02) and receiving brachytherapy/teletherapy (coefficient - 1.17, p < 0.01) were associated with higher reduction of vaginal dimensions.

CONCLUSIONS

Most women had mild vaginal stenosis with slight reductions in both diameter and length of the vaginal canal. Women with tumoral invasion of the vagina have an increase in vaginal length soon after radiotherapy due to a reduction in tumoral volume.

Development and validation of an individualized survivorship care plan (ISCP) for women with endometrial cancer during the transition of the end of active treatment to the cancer survivorship

Many cancer survivors finish their treatment without knowing the associated health risks and few are prepared to handle their health needs in the survivorship phase. Moreover, practical guides for follow- up care are not available and survivors' psychological and social needs often go unassessed. In this article, we propose the development and implementation of an individualized follow-up care plan (IFCP) after active treatment for women with endometrial cancers (WEC) to meet their needs for information and to facilitate the transition to the survivorship phase.

Background

The after-treatment phase is a distinct phase that is still neglected in the oncological continuum of care. It is the transition between two phases in the care trajectory-treatment and survivorship-that gives rise to many challenges for survivors, care providers and the healthcare system alike.

Research goal

Aiming to facilitate the transition between the end of active treatment and the cancer survivorship phases, we pursued two objectives: 1) Develop an individualized follow-up care plan (IFCP) based on both the literature and the perspective of WEC, healthcare professionals involved with the target clientele and oncology outreach managers, and 2) Have this IFCP validated by an interdisciplinary team.

Methodology

For the first objective, WEC-related needs at the end of active treatment (immediate end, three months and six months), as well as the perceptions of health professionals and oncology outreach managers were gathered by interview and group discussion on the benefit of an IFCP, its content and desired format. A content analysis of the interview data was performed using the Miles and Huberman approach (2003). For the second objective, an iterative consultation process with health professionals allowed for validation by consensus. These two objectives are the first qualitative phase of a mixed-methods sequential exploratory design that will make the development of an IFCP possible. In the second phase, we conducted a feasibility study of the implementation of the IFCP during the end of active treatment transition to cancer survivorship transition. This will be the subject of a second article.

Results

The interviews (n=47) revealed WECs' lack of preparation for the transition from the end of active treatment to the cancer survivorship. The following needs were specified: information (80%), emotional support, particularly to overcome their fear of recurrence (75%), the management of physical symptoms (45%), and support for adapting to change (45%). The data gathered from healthcare professionals and outreach managers support the utility of an IFCP in meeting these needs. The iterative validation process by the interdisciplinary team made consensus on the format and content possible. The final version of the IFCP is seen as a tool for information and communication in the survivorship phase. Some obstacles to its transfer to clinical practice are reported.

Conclusion

This study presents the entire process that led to the development of an IFCP that integrates both the needs of endometrial cancer survivors and the opinions of healthcare professionals and the oncology outreach managers organizing this care. Indications on how the IFCP could be implemented within this organization are also formulated.

Pelvic radiotherapy and sexual function in women

BACKGROUND

During the past decade there has been considerable progress in developing new radiation methods for cancer treatment. Pelvic radiotherapy constitutes the primary or (neo) adjuvant treatment of many pelvic cancers e.g., locally advanced cervical and rectal cancer. There is an increasing focus on late effects and an increasing awareness that patient reported outcomes (PROs) i.e., patient assessment of physical, social, psychological, and sexual functioning provides the most valid information on the effects of cancer treatment. Following cure of cancer allow survivors focus on quality of life (QOL) issues; sexual functioning has proved to be one of the most important aspects of concern in long-term survivors.

METHODS

An updated literature search in PubMed was performed on pelvic radiotherapy and female sexual functioning/dysfunction. Studies on gynaecological, urological and gastrointestinal cancers were included. The focus was on the period from 2010 to 2014, on studies using PROs, on potential randomized controlled trials (RCTs) where female sexual dysfunction (FSD) at least constituted a secondary outcome, and on studies reporting from modern radiotherapy modalities.

RESULTS

The literature search revealed a few RCTs with FSD evaluated as a PRO and being a secondary outcome measure in endometrial and in rectal cancer patients. Very limited information could be extracted regarding FSD in bladder, vulva, and anal cancer patients. The literature before and after 2010 confirms that pelvic radiotherapy, independent on modality, increases the risk significantly for FSD both compared to data from age-matched healthy control women and compared to data on patients treated by surgery only. There was only very limited data available on modern radiotherapy modalities. These are awaited during the next five years. Several newer studies confirm that health care professionals are still reluctant to discuss treatment induced sexual dysfunction with patients.

CONCLUSIONS

Pelvic radiotherapy has a persistent deteriorating effect on the vaginal mucosa impacting negatively on the sexual functioning in female cancer patients. Hopefully, modern radiotherapy modalities will cause less vaginal morbidity but results are awaited to confirm this assumption. Health care professionals are encouraged to address potential sexual dysfunction both before and after radiotherapy and to focus more on quality than on quantity.

A prospective study in the evaluation of quality of life after vulvar cancer surgery

OBJECTIVE

The aim of this study was to prospectively monitor the patients' quality of life (QoL) after vulvar cancer surgery.

DESIGN

The design was prospective clinical study.

SETTING

The study was set in the Department of Obstetrics and Gynecology, 2nd Medical Faculty of the Charles University and University Hospital Motol, Prague, Czech Republic.

METHODS

A group of 36 patients underwent vulvar cancer surgery: 24 patients were subject to inguinofemoral lymphadenectomy (RAD) and 12 to sentinel lymph node biopsy. To evaluate QoL, the European Organisation for Research and Treatment of Cancer, QoL questionnaires (QLQ-C30 and QLQ-CX24) were administered to patients before and 6 and 12 months after surgery.

RESULTS

In patients with vulvar cancer after inguinofemoral lymphadenectomy, increased fatigue and impaired lymphedema were observed. In the group of patients after sentinel lymph node biopsy, none of the QoL variables worsened postoperatively. Comparing both groups 12 months after surgery, the RAD group had significantly worse outcomes in body image and cognitive functioning than the sentinel lymph node biopsy group.Patients in the RAD group, who received adjuvant radiotherapy (n = 13), had worse QoL in symptom experience (P < 0.05) at 6 and 12 months after the surgery than patients without radiotherapy (n = 11).

CONCLUSIONS

Less radical surgery showed objectively better QoL results.

Biopsychosocial predictors of pain among women recovering from surgery for endometrial cancer

OBJECTIVE

This study investigated post-surgical changes in pain among endometrial cancer patients, as well as the extent to which emotional distress and inflammatory and regulatory cytokine levels were associated with pain.

METHODS

Women (N=71) who underwent surgery for endometrial cancer completed questionnaires assessing pain intensity and interference, depression, and anxiety at 1week, 4weeks, and 16weeks post-surgery. Participants also provided a blood sample for the analysis of a panel of 7 cytokines at the same time points.

RESULTS

Participants showed significant declines in pain intensity and pain interference from 1week to 4weeks post-surgery, after which pain remained stable. After adjusting for time since surgery, surgery type, adjuvant therapy, disease stage, age, and BMI, mixed-effects linear regression models indicated that greater depression and anxiety were associated with both greater pain intensity and interference. Higher levels of circulating IL-6 were also correlated with greater pain intensity, but not interference. Fixed-effects linear regression models indicated that temporal variation in depression, anxiety, and IL-6 within individual patients was associated with corresponding changes in pain. Pain symptoms were maximal when anxiety, depression, and IL-6 were highest. No other cytokines were associated with changes in pain.

CONCLUSION

These findings indicate that depression, anxiety, and IL-6 may exacerbate pain during the recovery period following surgery for a gynecologic malignancy. Targeting these psychological processes and the proinflammatory cytokine IL-6 in women with more severe and persistent pain may help to reduce suffering and improve post-surgical recovery.

Sexual function and quality of life in women with cervical cancer before radiotherapy: a pilot study

PURPOSE

To achieve a better understanding of issues related to sexual function and quality of life (QOL) of women with cervical cancer before radiotherapy treatment.

METHODS

A pilot study with 80 women with cervical cancer from Jan/2013 to Mar/2014. The outcome variables were sexual function assessed using the Female Sexual Function Index (FSFI) and QOL, assessed using the World Health Organization questionnaire. Independent variables were clinical and sociodemographic data. Statistical analysis was carried out using Student's t test, Mann-Whitney test, ANOVA and multiple linear regression.

RESULTS

The mean age was 48.1 years, 57.5 % were premenopausal and 55 % had clinical stage IIIB. Thirty percent had been sexually active in the 3 months prior to their interviews. The main adverse events during sexual intercourse were bleeding (41.7 %), lack of pleasure (33.3 %), dyspareunia (25 %), and vaginal dryness (16.7 %). The 18 women who had been sexually active in the previous month showed significant sexual dysfunction (total mean FSFI score = 25.6). Advanced clinical stage, using any chronic medication and not having undergone surgery for cancer were negatively correlated with QOL. Higher family income, a longer duration of schooling and no smoking were positive correlated with QOL.

CONCLUSIONS

One-third of women with cervical cancer were sexually active 3 months prior to their interviews, but have concomitant significant sexual dysfunction. Factors related to the disease are primarily responsible for the deterioration of sexual function. QOL is influenced not only by factors related to the cancer itself, but also by lifestyle habits, comorbidities, and sociodemographic characteristics.

Bladder and bowel symptoms in cervical and endometrial cancer survivors

BACKGROUND

Previous studies likely underestimate the prevalence of bowel and bladder symptoms in gynecologic cancer survivors. We sought to estimate the prevalence of these symptoms in cervical and endometrial cancer survivors who had completed treatment 1 year previously compared with non-cancer controls, and to examine factors associated with more severe symptoms in survivors.

METHODS

As part of a larger quality of life study, survivors who were 1-year posttreatment for cervical or endometrial cancer (n = 104) completed measures of bladder and bowel symptoms. An age-matched and race/ethnicity-matched sample of women with no history of cancer was recruited for comparison purposes.

RESULTS

Survivors reported a higher prevalence of bladder symptoms, specifically storage and incontinence symptoms, than non-cancer controls. Prevalence rates for bowel symptoms in survivors were higher than those reported in previous studies. Greater symptom severity was associated with younger age, lower annual incomes, and less education. Other correlates included higher body mass index and history of smoking. As hypothesized, more severe symptoms were associated with radical hysterectomy and pelvic radiation.

CONCLUSIONS

Bladder and bowel symptoms are more prevalent in cervical and endometrial cancer survivors than non-cancer controls. Future research should replicate these findings in a larger, prospective study.

Quantity vs. quality: an exploration of the predictors of posttreatment sexual adjustment for women affected by early stage cervical and endometrial cancer

INTRODUCTION

Women with early stage cervical and endometrial cancer may experience complex posttreatment changes to their sexual function, but clinical practice and past research have focused more on the quantity than the perceived quality of sexual life.

AIM

The aims of this prospective study were to explore the following: (i) the relative importance of quantity vs. quality of sexual life over the first year posttreatment; (ii) the psychological and sexual predictors of overall sexual function; and (iii) the relationship between sexual function and quality of life (QoL).

METHODS

Fifty-three cancer patients completed standardized measures at baseline, with follow-up at 6 and 12 months posttreatment. Analyses were based on prespecified linear mixed models with overall sexual function and QoL as outcomes, and quality and quantity of sexual life, anxiety, and depression as the main predictors of interest. Radiotherapy, age, and relationship satisfaction were controlled for as potential confounders.

MAIN OUTCOME MEASURES

Derogatis Sexual Functioning Inventory subscales to assess quantity (Drive) and quality (Satisfaction) of sexual life, and overall sexual function (Global Sexual Satisfaction Index); Functional Assessment of Cancer Therapy--General to assess QoL; Hospital Anxiety and Depression Scale to assess psychological distress; and Relationship Satisfaction Interaction Scale to assess relationship satisfaction.

RESULTS

The models demonstrated that: (i) overall sexual function was predicted more strongly by the perceived quality than the quantity of sexual interactions, (ii) a small change in perceived quality had a large impact on overall sexual function, and (iii) overall sexual function was a predictor of QoL.

CONCLUSION

This study found that quality rather than quantity of sexual life is the best predictor of overall sexual function among women treated for early stage cervical and endometrial cancer, indicating the importance of including quality indices in posttreatment sexual assessment in clinical practice and research studies.
