Vaginal changes, sexual functioning and distress of women with locally advanced cervical cancer treated in the EMBRACE vaginal morbidity substudy

The impact of gynecologic cancer on female sexuality in Europe and MENA (Middle East and North Africa): a literature review

INTRODUCTION

Gynecologic cancer has a negative impact on the sexuality of women who are or have been affected by this disease. In fact, gynecologic cancers cause negative changes in female sexuality, affecting body image and psychophysical well-being, with serious consequences for women's sex lives.

OBJECTIVES

The aim of this study is to analyze the differences in sexuality among women who have or have had gynecologic cancer in Europe and in the Middle East and North Africa (MENA). We also explored possible factors that may influence women's sexuality in the 2 populations compared.

METHODS

The literature search was carried out using PubMed and Google Scholar, considering the 10-year period of 2013 to 2023. Studies were initially selected according to the criterion that the title and abstract were in English. We then reviewed all the articles selected in the first phase and analyzed the following information: author, year of publication, type of gynecologic cancer, country in which the study was conducted, design, and materials used. Finally, we defined the inclusion criteria for the present paper: women 18 years of age or older, diagnosed with gynecologic cancer, and who had undergone treatment (surgery, chemotherapy, radiotherapy). The studies reviewed were conducted between 2013 and 2023 in Europe and MENA, and all analyzed sexual function after the disease, understood as a general dimension that includes physiological and psychological aspects.

RESULTS

The results of this research show that patients in both geographical areas (Europe and MENA) report changes in sexuality as a result of the cancer. Studies show that cancer reduces, interrupts, and impairs women's sexual activity, resulting in experiences of discomfort, anxiety, guilt, inadequacy, pain, and poorer quality of life.

CONCLUSIONS

The data analyzed in this review show that cancer causes changes and deterioration in sexuality in both populations studied. No cultural or social factors were found to cause differences between the variables studied in the 2 populations. In the future, it may be interesting to carry out further studies to improve the treatment of women with gynecologic cancer, as sexuality is a very important part of a person's life.

Predictive Factors for Toxicity After Primary Chemoradiation for Locally Advanced Cervical Cancer: A Systematic Review

PURPOSE

Women with locally advanced cervical cancer (LACC) undergoing primary platinum-based chemoradiotherapy and brachytherapy often experience toxicities. Normal-tissue complication probability (NTCP) models quantify toxicity risk and aid in optimizing radiation therapy to minimize side effects. However, it is unclear which predictors to include in an NTCP model. The aim of this systematic review was to provide an overview of the identified predictors contributing to gastrointestinal (GI), genitourinary (GU), and vaginal toxicities and insufficiency fractures for LACC.

METHODS AND MATERIALS

A systematic search was performed and articles evaluating the relationship between predictors and toxicities in women with LACC treated with primary chemoradiation were included. The Quality In Prognosis Studies tool was used to assess risk of bias, with high-risk studies being excluded from further analysis. Relationships between dose-volume parameters, patient and treatment characteristics, and toxicity endpoints were analyzed.

RESULTS

Seventy-three studies were identified. Twenty-six had a low or moderate risk of bias and were therefore included. Brachytherapy-related dose-volume parameters of the GI tract, including rectum and bowel equivalent dose in 2 Gy fractions (EQD2) D2 cm3, were frequently related to toxicities, unlike GU dose-volume parameters. Furthermore, (recto)vaginal point doses predicted toxicities. Few studies evaluated external beam radiation therapy dose-volume parameters and identified rectum EQD2 V30 Gy, V40 Gy, and V55 Gy, bowel and bladder EQD2 V40 Gy as toxicity predictors. Also, total reference air kerma and vaginal reference length were associated with toxicities. Relationships between patient characteristics and GI toxicity were inconsistent. The extent of vaginal involvement at diagnosis, baseline symptoms, and obesity predicted GU or vaginal toxicities. Only 1 study evaluated insufficiency fractures and demonstrated lower pretreatment bone densities to be associated.

CONCLUSIONS

This review detected multiple candidate predictors of toxicity. Larger studies should consider insufficiency fractures, assess dose levels from external beam radiation therapy, and quantify the relationship between the predictors and treatment-related toxicities in women with LACC to further facilitate NTCP model development for clinical use.
