Background: Prophylactic Bilateral Salpingo-Oophorectomy (PBSO) reduces the risk of developing ovarian cancer. However, the psychological mechanisms that may affect post-surgery Quality of Life (QoL) among patients who underwent PBSO are still largely unknown. Thus, this study aimed at exploring the direct and indirect associations of satisfaction with medical communication and cancer anxiety on post-surgery QoL among women at high risk of developing ovarian cancer.
Method: Fifty-nine women (mean age: 50.64 ± 6.7 years) who underwent PBSO took part in this cross-sectional study, filling out a sociodemographic and clinical questionnaire, a battery of validated psychological measures and an ad hoc developed scale for the assessment of cancer anxiety. We first examined the correlations among all variables of interest, and then tested if cancer anxiety mediated the association between satisfaction with medical communication and post-surgery psychological QoL, controlling both for time from surgery and education.
Results: Post-surgery psychological QoL was unrelated from any sociodemographic or clinical variable. Cancer anxiety had a significant direct negative effect on psychological QoL, while satisfaction with medical communication had a significant positive direct effect on it. Finally, cancer anxiety significantly mediated the association between satisfaction with medical communication and post-surgery psychological QoL.
Discussion: Results suggest that post-surgery psychological QoL of patients who underwent PBSO may be increased with interventions, delivered in a genetic counselling setting, targeting quality of medical communication and cancer anxiety.
Introduction
Each year, ovarian cancer accounts for an estimated 239,000 new cases and 152,000 deaths worldwide (Ferlay et al., 2015). Despite recent improvements in detection and treatment, mortality is still high and data relating to its distribution are still alarming. In this context, genetic tests that evaluate the inherited tendency to develop ovarian cancer are particularly useful, as they allow to prevent cancer’s onset and, consequently, to reduce the mortality rates (Bleiker et al., 2003). In the gynecological field, recent studies have shown that women with the BRCA (BReast CAncer) gene 1 or 2 mutation have a significantly increased lifetime risk of developing both breast (from 39 to 85%) and/or ovarian cancer (from 10 to 63%)(Ford et al., 1998; Meijers-Heijboer et al., 2001; Antoniou et al., 2003). In case of a family history of breast\gynecological cancer or of a BRCA 1/2 mutation, the medical team may recommend (based on age, the desire for parenting, and other clinical considerations for that specific patient) an intensive screening or even perform a prophylactic surgery. In some cases, surgery (i.e., prophylactic mastectomy and/or prophylactic bilateral salpingo-oophorectomy) is recommended as it substantially reduces the risk of developing breast or ovarian cancer (Schrag et al., 1997; Meijers-Heijboer et al., 2001).
Quality of Life After PBSO
Despite the significant psychological impact that performing a Prophylactic Bilateral Salpingo-Oophorectomy (PBSO) may represent, few studies have examined the patients’ post-surgery Quality of Life (QoL), reporting mixed results. That is, women who underwent PBSO report a reduction of both worry related to the risk of developing cancer and psychological distress after the surgery (i.e., a higher positive wellbeing and a reduction in anxious or depressive symptoms), but at the same time they often show menopausal symptoms, an alteration of body image (including feeling less physically attractive), a reduced sexual functioning (i.e., satisfaction with sexual functioning, libido reduction, vaginal dryness, reduced sexual arousal, and lubrification) and vitality, poorer physical and social functioning, physical role limitations, and higher pain intensity (Meiser et al., 2000; Elit et al., 2001; Tiller et al., 2002; van Oostrom et al., 2003; Aziz et al., 2005; Madalinska et al., 2005; Bresser et al., 2007a; Fang et al., 2009; Michelsen et al., 2009; Razzaboni et al., 2012; Finch et al., 2013; Borreani et al., 2014; D’Alonzo et al., 2018; Hickey et al., 2021a; Islam et al., 2021; Kershaw et al., 2021; Philp et al., 2021). However, in most cases, the negative effects of PBSO (i.e., vaginal discomfort and impairment of quality of life) significantly decrease after 6 months or 1 year after surgery, even if a smaller percentage of patients experience long-term impairments, such as cancer-related distress (from 18% to 22/27%) and anxiety (19%), which need to be further investigated (Bresser et al., 2007a; Fang et al., 2009; Finch et al., 2013). Interestingly, Hickey et al. (2021b) found an increase in depressive and anxious symptoms after a PBSO surgery. During the 12-months post-surgery follow-up depressive symptoms persisted while anxiety symptoms returned to baseline (Hickey et al., 2021b).
Literature has identified several risk and protective factors for long-term post-surgery QoL outcomes among women who undergo BPSO. For example, being a BRCA mutation carrier, having younger children, the loss of a relative due to breast/ovarian cancer, limited open communication about the test results within the family, changes in relationships with relatives, being in premenopausal status at operation, doubting about the validity of the test results, a greater risk perception, higher educational level, and occupying an executive position are important predictors of lower post-surgery general QoL (Fry et al., 2001; van Oostrom et al., 2003; Bresser et al., 2007b; Touboul et al., 2011; Tucker et al., 2016). Conversely, positive coping strategies like having comforting thoughts are predictive of higher post-surgery general QoL (Bresser et al., 2007b). In addition, anxiety and cancer anxiety (i.e., anxiety symptomatology specifically related to the worry of developing cancer) may also play a significant role in affecting post-surgery QoL.
Medical Communication and Post-surgery Outcomes
One could argue that satisfaction with medical communication about the genetic counselling, procedures related to the surgery, and post-surgery recovery may constitute an important protective factor for a good post-surgery psychological QoL and recovery. It is well known that an efficient and good communication—characterized by a positive patient-physician alliance, information sharing, and by a greater ability to foster patient’s feelings of control and mastery—has an overall positive effect on the psychological wellbeing of patients (Hack et al., 2005). In particular, a good medical communication influences the perception of control about the treatment, the overall compliance with the treatment, frequency of symptoms, self-management skills, engagement in preventive health behaviors, satisfaction for the surgery’s choice, QoL, anxiety, and depression (Kretsch et al., 2014). To date, literature has highlighted that women at high risk for cancer frequently claim for insufficient information to make an informed decision about the choice to carry out the surgery (Hallowell, 1998). The study of Trister et al. (2021) found that 43% of the women undergoing BSO did not feel well informed about what to expect post-operatively.
They further report the need for supportive communications (Babb et al., 2002), in particular relative to the effects of surgical menopause, the link between Hormone Replacement Therapy (HRT) and breast cancer (Meiser et al., 2000), and potential physical and emotional effects of the surgery (Hallowell, 1998).
Literature Limitations and Current Study
Literature on this population has several shortcomings. In accordance with Finch and Narod (2011), well performed follow-up studies on the long-term health and quality of life consequences of BPSO are still missing. Furthermore, to date, very few studies focused on the role of medical communication in the field of genetic counselling or prophylactic surgery, and no studies focused on cancer anxiety after BPSO, nor on the relationship between anxiety and QoL in this population.
In order to overcome these limits, we tested a mediation model in a population of PBSO patients, where the association between satisfaction with medical communication (i.e., the level of satisfaction regarding the medical communication received during the surgery pathway) and post-surgery psychological QoL is mediated by cancer anxiety. In accordance with Stark and House (2000), we hypothesized that a greater satisfaction with medical communication will reduce the overall levels of cancer anxiety, leading to a greater post-surgery psychological QoL.
Materials and Methods
Participants and Procedure
A total of 59 consecutive women (mean age: 50.64 ± 6.7 years) who underwent PBSO volunteered for this retrospective study. Participants were recruited from January to July 2019 in two hospitals located in North Italy and were approached during their yearly follow-up visit after the PBSO surgery (median time from surgery: 2 years). We included women aged 18+ years, who underwent PBSO in the last 5 years for different reasons (i.e., history of breast cancer, BRCA 1/2 genetic mutation, presence of ovarian diseases, or a family history of cancer), free of past or concurrent neurological and psychiatric diseases or severe medical conditions, and proficient in written and spoken Italian. Sociodemographic and clinical data, including means and standard deviations for all psychological variables, have been reported in Table 1. The majority of the participants attended high school (54.2%), was married (74.6%), and was currently working (72.9%). From a clinical point of view, they were mostly diagnosed with a BRCA 1/2 genetic mutation (81.6%) or had a history of breast cancer (67.8%) treated with a mastectomy (66.1%).

Measures
Primary Measures
Satisfaction With Medical Communication
Satisfaction with medical communication received in relation to the surgery was assessed through a single item on a Likert-type scale (i.e., from 0 = “completely unsatisfied” to 10 = “completely satisfied”). The item asked patients “From 0 (completely unsatisfied) to 10 (completely satisfied), how much satisfied are you with the medical information you received before and after the prophylactic surgery?”
Quality of Life
Post-surgery QoL (physical, psychological, and social; α ranges in the current study: 0.71 to 0.84) was assessed using the Italian version of the World Health Organization Quality of Life -bref (WHOQoL-bref; De Girolamo et al., 2000). The WHOQoL-bref is a self-administered questionnaire comprising 26 questions on the individual’s perceptions of their health and wellbeing over the previous 15 days. Responses are on a 5-point Likert-type scale (from 1 = “disagree”\"not at all” to 5 = “completely agree”\"extremely”). The scale covers four domains, namely Physical health (seven items), Psychological QoL (six items), Social relationships (three items), and Environment QoL (eight items). There are also two items that are examined separately: question 1 asks about an individual’s overall perception of quality of life and question 2 asks about an individual’s overall perception of their health. In the present study, the Environment subscale was not included in the protocol. The total scores of each subscale range from 4 to 20, with higher scores indicating a greater QoL in that specific domain. Each score is calculated through a detailed syntax described in the manual of the instrument (World Health Organization, 1996).
Cancer Anxiety
Cancer anxiety was examined through an ad hoc developed cancer anxiety scale, composed by two Likert-type items investigating both “Cancer rumination” and “Cancer risk perception.” The items asked patients to rate from 0 (“not at all”) to 10 (“very much”) how much they experienced the following mental states: (a) “I have recurring thoughts about cancer” (Cancer rumination); “I have the perception that my life is constantly threatened” (Cancer risk perception). Cancer anxiety total score is calculated by the mean of the two items and ranges from 0 to 10. Higher scores indicate higher cancer anxiety.
Secondary Measures
Sociodemographic and clinical information were collected using a structured ad-hoc self-report questionnaire.
Sexual Functioning
Sexual functioning was assessed through the Italian version of the Female Sexual Function Index (FSFI; α in the current study: 0.96; Filocamo et al., 2014). The FSFI is a 19-items scale aimed at targeting the six domains of female sexual functioning: desire (two items, range 2–10), arousal (four items, range 0–20), lubrication (four items, range 0–20), orgasm (three items, range 0–15), satisfaction (three items, range 2–15), and pain (three items, range 0–15). Items of all subscales, except for desire and satisfaction, are rated on a 6-point Likert-type scale (from 0 to 5), while the items of the subscales desire and satisfaction are rated on a 5-point Likert-type scale (from 1 to 5). Items 14, 15, and 16 are reverse-scored. The total score ranges from 4 to 95, with higher scores indicating a better sexual functioning.
Sexual Distress
Sexual distress was investigated through the Female Sexual Distress—revised (FSDS-r; α in the current sample: 0.97; Derogatis et al., 2008), a 13-items scale aimed at assessing distress related to sexuality. Respondents indicate how often each of the listed sexual-related problems (e.g., absence of desire and feeling of guilty) has caused distress in the previous 7 days on a Liker-type scale from 0 (“never”) to 4 (“always”). Total score ranges from 0 to 52, with higher scores indicating greater sexual distress. The Italian translated version provided by the authors (copyright: American Foundation for Urological Disease Inc.) has been used in this research study.
Body Image Distress
Body image distress was assessed through the Italian version of the Body Image Scale (BIS; α in the current sample: 0.93; Cheli et al., 2016). The BIS is a 10-item measure of different dimensions of body image in cancer patients. It uses a 4-point response scale (from 0 = “not at all,” to 3 = “very much”). Total scores range from 0 to 30, with higher scores indicating worse symptoms and distress or more body image concerns. In this study, we aimed at assessing body image beliefs in the last week and in relation to surgery consequences.
Statistical Analysis
We performed an a priori power analysis (F test family and linear multiple regression with two predictors as statistical test) using the software G*POWER 3.1. We first extracted effect sizes from a similar study on QoL of women at high risk for breast cancer who underwent a prophylactic surgery (f2 = 0.17; Brandberg et al., 2008). The a priori power analysis evidenced that 60 participants were required to detect a medium-high effect size (f2 = 0.17) on psychological QoL (α = 0.05; Power = 0.80). Hence, our study had adequate power.
Data were initially screened for assumptions. Thus, we tested for the presence of univariate and multivariate outliers, and examined the univariate normality of all variables of interest (Tabachnick and Fidell, 2007). We then investigated the possible relationships between sociodemographic, clinical, and psychological variables, and post-surgical psychological QoL, through Pearson’s or Spearman’s r correlation coefficients.
We tested our main hypothesis on the mediating effect of cancer anxiety on the association between satisfaction with medical communication (i.e., the independent variable) and post-surgery psychological QoL (i.e., the dependent variable), while controlling both for time from surgery and educational level (grouped into “low education” and “high education,” with a cut-off of 8 years of education), through a bootstrapped test of mediation analysis. The analysis was conducted by using Hayes’ PROCESS Mediation Model version 3.4, which is a conditional process modeling program that utilizes an ordinary least squares-based path analytical framework to test for both indirect and direct effects (Hayes, 2017). Our hypothesis was tested adopting Model 4 in PROCESS (i.e., a simple mediator model; see Figure 1). We used random sampling with replacement to generate 5,000 bootstrap samples. This approach produces bias-corrected estimates of the standard errors of parameter estimates and a bias-corrected 95% confidence interval (CI) of the mediation effects. If the 95% CI for the hypothesized indirect effect does not include zero, the indirect effect is significant at p ≤ 0.05 (Hayes, 2017). Effect sizes were reported and interpreted according to guidelines (Cohen, 1988).

All analyses were run with SPSS version 26 (SPSS, 2019). All tests were two tailed, and a value of p ≤ 0.05 was considered significant.
Results
Preliminary Analyses
Preliminary analyses evidenced that all variables were normally distributed, while no univariate or multivariate outliers were identified. Further, the cancer anxiety scale specifically developed for this study evidenced good psychometric properties: a Principal Component Analysis with one extracted component explained 93.65% of the variance, and both items had a saturation of 0.97 with the factor “cancer anxiety.” The internal consistency was also good, with a Cronbach’s α of 0.93.
Correlational analyses (see Table 2) suggested positive associations between post-surgery psychological QoL and social QoL (r = 0.631; p < 0.001), physical QoL (r = 0.724; p < 0.001), and satisfaction with medical communication (r = 0.365; p < 0.001), with medium-to-large effects. In addition, post-surgery psychological QoL was negatively correlated with body image distress (r = −0.406; p < 0.001) and cancer anxiety (r = −0.490; p < 0.001), with medium effects. Finally, post-surgery psychological QoL was unrelated from sociodemographic and clinical variables, nor from the time passed since prophylactic surgery (see Table 2).

Mediation Model
We tested our main hypothesis on the mediating effect of cancer anxiety (i.e., the mediator) on the association between satisfaction with medical communication (i.e., the independent variable) and post-surgery psychological QoL (i.e., the dependent variable), while controlling both for time from surgery and educational level. Our mediation model (see Figure 1) evidenced that the satisfaction with medical communication was a significant negative direct predictor of cancer anxiety (β = −0.285, p = 0.032), with medium effects. Further, cancer anxiety had a significant negative direct effect on post-surgical psychological QoL (β = −0.392, p = 0.001), while satisfaction with medical communication was a significant positive predictor of the dependent variable (β = 0.345, p = 0.004), with medium effects. Finally, cancer anxiety mediated the association between satisfaction with medical communication and post-surgical psychological QoL (β = 0.112, SE = 0.058, 95% CI [0.023, 0.245]), with medium effects This model accounted for approximately 35% of the variance in the dependent variable.
Discussion
This study sought to investigate if cancer anxiety mediated the association between satisfaction with medical communication and post-surgery psychological QoL, in a sample of women who underwent PBSO. Findings suggested that, among patients who underwent PBSO, a greater satisfaction with medical communication decreases cancer anxiety, which in turn improves post-surgical psychological QoL. To the best of our knowledge, very few studies have investigated QoL after BPSO, and even fewer examined the predictors of long-term post-surgery QoL within this sample. Our study provided a significant contribution to this emerging topic, focusing on the needs and shortcomings of the current literature.
We found that post-surgery psychological QoL was unrelated from any sociodemographic and clinical (i.e., BPSO or health related) factors. That is, the psychological QoL of women who underwent BPSO seems to be modulated by other individual factors, such as the psychological ones. Our results differ from those reported by Touboul et al. (2011) where the post-surgical QoL of women who underwent BPSO was positively associated with higher education and an executive working position. We also found that menopause status before surgery, BRCA 1/2 genetic mutation diagnosis, history of breast cancer, and of previous cancer treatments were not associated with post-surgery psychological QoL. These results are similar to most of those reported both in Finch et al. (2013) and Touboul et al. (2011), even if Finch et al. (2013) found that a history of breast cancer predicted a lower physical QoL after BPSO.
Furthermore, we found that body image distress was negatively associated with post-surgery psychological QoL. Therefore, post-surgery psychological QoL may be partially explained by the perceived body image resulted from the surgery (i.e., distress for weight gain and scars). This finding is particularly interesting and need further investigation since most of the current literature has focused exclusively on body image distress after a mastectomy (Aygin and Cengiz, 2018; Huang and Chagpar, 2018).
Counselling and quality of communication in this field are important. Trister et al. (2021) highlighted that, despite patients usually receive pre-surgery counselling, there is a need to provide supplemental patient materials in preparing patients for what to expect after surgery. We provided more information about the significant role of counselling in this context. Indeed, we found that satisfaction with medical communication significantly affect both post-surgery cancer anxiety and psychological QoL. In particular, our result suggested that a greater satisfaction with medical communication directly increases post-surgery psychological QoL and reduces cancer anxiety. In turn, reduced cancer anxiety leads to a greater psychological QoL. In accordance with Kretsch et al. (2014), we hypothesize that a greater quality of medical communication, focused on providing accurate information on (i) the risk condition or genetic predisposition, (ii) possible prophylactic surgeries, and (iii) post-surgery recovery, using an emphatic and patient-centered style, may be associated with a greater satisfaction with medical communication. This, in turn, may enhance both the patients’ self-efficacy competencies and their focus on an internal locus of control (i.e., the beliefs that the outcomes of one own’s actions are results of one own abilities and choices). Thus, thanks to a greater satisfaction with medical communication, patients who underwent PBSO may experience psychological changes that promote psychological QoL and reduce perceived risk and rumination on cancer.
Limitations
Despite the clinical significance of our findings, the limited sample size, the retrospective assessment of the satisfaction with medical communication, and the use of an ad-hoc measure of cancer anxiety may limit the generalizability of our findings. The retrospective assessment of the satisfaction with medical information could have been affected by a recall bias, even if we tried to partially control for this systematic error entering time from surgery as a covariate in our mediation model. In addition, satisfaction with medical communication and quality of medical communication are partially overlapping—but still distinct—dimensions. Indeed, the former may be influenced by other personal or clinical factors (e.g., personal expectations, complications related to the surgery, previous surgery for breast cancer, symptomatology perception, and the impact of induced menopause), not per se reflecting the quality of the communication. Finally, satisfaction with medical communication may also be affected by health literacy and education, even if we tried to partially control for this including educational level as covariate in the mediation model.
Conclusion
Findings support the importance to guarantee high quality of counselling provided to women undergoing PBSO. To reach this goal, it could be helpful (i) to include mental health practitioners within the genetic screening procedure or as part of the pre-surgical evaluation team and (ii) to deliver specific communication-based trainings for the medical team aimed at reducing the cancer anxiety experienced by patients. High-quality medical communication and greater patients’ satisfaction could help those who undergo PBSO to better cope with the long-term psychological sequelae of prophylactic surgery, reducing the possible distress, and increasing—in the long run—their overall sense of wellbeing and QoL. Better satisfaction with BPSO and subsequent greater QoL might be in turn related to a wider diffusion of prophylactic surgical treatments and the maximization of ovarian cancer prevention.
