Assessment of sexual function and quality of life in breast cancer patients before and after the occurrence of therapy-related skin changes

Background Patients with breast cancer (BC) who receive adjuvant chemotherapy or other treatment modalities may potentially benefit from an enhanced prognosis of survival. Physical or aesthetic complications may, nevertheless, result in significant distress as a consequence of adverse dermatologic responses. There has been a heightened focus on matters related to quality of life (QoL) as the number of BC survivors has risen. Sexual disorders are reported by as many as 75% of women who undergo treatment for BC. Despite this, the majority of oncologists lack the necessary training to identify patients who are particularly susceptible to developing sexual disorders. Patients diagnosed with BC frequently experience female sexual dysfunction. Objective To compare and evaluate the impact of skin changes induced by different treatment modalities in BC patients on their sexual function and QoL. Patients and methods This is a prospective cohort research on 58 cases diagnosed with BC, which was conducted in the outpatient clinic of the Clinical Oncology department, Faculty of Medicine, Menoufia University from April 2022 to February 2023. The calculated sample size for the current study using Epi info 7 programs was 56 women. The power of the study is 80% with a confidence level of 95% as determined by the Public Health and Community Medicine Department, Faculty of Medicine, Menoufia University. Both sexual function and QoL were assessed before and 3-6 months after the occurrence of skin changes related to different treatment modalities using validated questionnaires irrespective of their tumor stage. Results Of the 58 patients, there was statistically significant variance regarding dermatological life quality index (DLQI) (P<0.001), with 8.6% of patients experiencing a very large influence on their QoL, which increased to 19%. However, the number of patients having an extremely large influence on their quality of life changed from 0 to 5.2%. There was statistically significant variance (P<0.001) regarding female sexual function index values among the six domains of female sexual function index before and after the occurrence of skin changes. There is a negative correlation between DLQI score and desire, arousal, lubrication, orgasm, and satisfaction scores, while there is a positive correlation between DLQI score and pain score. QoL was negatively affected by the occurrence of such skin lesions. Conclusion There was a significant negative impact of skin changes induced by different treatment modalities in BC patients on their sexual function and QoL.
