Abstract: Our aim was to summarize the current relevant literature on concomitant psychiatric symptoms with a focus on anxiety/depression in a population with gynecologic cancer; to identify the predictors, associated factors, and prevention strategies of psychiatric disorders; to examine psychiatric disorders in a population with recurrent gynecologic cancer; and to describe the limitations of the literature and future research areas. Little is known about attending psychiatric disorders in patients with gynecologic and other malignant diseases like cervical or breast cancer. However, patients suffering from other types of gynecologic cancer (eg, genital/cervical cancer) may also have an increased risk of psychiatric symptoms. In this review, we identify the potential information deficits in this field. A two-rater independent literature search was conducted using the PubMed/Google Scholar search engines to systematically evaluate the literature on the research objectives, followed by a critical reflection on the results. Of the 77 screened studies, 15 met the criteria for inclusion in this review. Patients with gynecologic malignancies, especially cervical cancer, had a very high prevalence of psychiatric symptoms including depression (33%–52%). Additionally, the risk groups facing higher rates of concomitant reduced quality of life and increased psychiatric symptoms such as depression were identified. Specifically, low socioeconomic status, sexual inactivity, absence of a partner, and physical symptoms were correlated with an increased risk. Patients suffering from recurrent gynecologic cancer should receive particular attention because of their significantly increased risk of depressive symptoms. Screening programs are needed to detect psychiatric symptoms in cervical cancer patients and the associated high-risk groups. Regular screening should be implemented, and psychosocial care should be provided during follow-up.

Mental disorders, defined as specific impairments in domains such as affect, perception, and (social) interaction, are common diseases. Somatic and/or social stressors impact the functioning of mental and physiological systems, which are attuned to complex interactions among social, cultural, and interactional factors. In the European Study of the Epidemiology of Mental Disorders, 14% of the general European population reported a lifetime history of some type of mood disorder and 13.6% reported a lifetime history of anxiety.1 Probands with somatic diseases such as cancer are known to be at risk of concomitant psychiatric symptoms such as depression and anxiety, as well as reduced quality of life (QoL). In the general cancer population, the prevalence of depression ranges from 8%–24% (depending on the type of instrument used, the type of cancer, and the treatment phase).2 There is a significant overlap between psychiatric symptoms and cancer with somatic symptoms such as fatigue, pain, poor sleep, and concentration.3,4 Breast cancer is the most common malignant disease in women, with 458,000 affected women in Europe for an age-standardized incidence of 71 per 100,000 women and high mortality (16 per 100,000 European women). In addition, the mortality from this malignancy is higher than that from any other cancer.5 Breast cancer is also the type of cancer in which concomitant psychiatric symptoms such as anxiety/depression, impaired QoL, and psychosocial impairments have been studied the most.6,7 According to systematic reviews and meta-analyses, the prevalence of depression in breast cancer patients ranges from 20% to over 50%, which is much higher than the rate in the normal population.8–11 Indeed, studies have postulated that women with breast cancer may have an increased risk of depression.12–14 The therapeutic approach to breast cancer is based on a large body of evidence,15–18 and there is increasing interest but still very limited data regarding attending psychiatric diseases in female patients with gynecologic, genital, and cervical cancer.19–21 Patients suffering from different types of gynecologic cancer (genital/cervical cancer) may also have an increased risk of developing an attending psychiatric disease, but little is known about attending psychiatric disorders in patients with cancers other than breast cancer, such as gynecologic cancer.
In total, 185,000 women in Europe newly develop genital/cervical cancer each year.22–24 Therefore, with disparities between ethnic and geographical regions, cervical cancer is the most common genital malignancy in women worldwide, with an incidence of 500,000 cases/year and a very high mortality of at least 300,000 deaths/year.25–27
Therefore, the aim of this mini-review, which was based on a current literature search, was to investigate the current knowledge on attending psychiatric disorders in a group of women with gynecologic cancer.
Cervical cancer does not initially cause pain, and only occasional spotting is reported. Because of these lack of symptoms, it is rarely detected in the early stage.26 From the moment the cancer is diagnosed, treatment for cervical cancer includes multiple modalities such as surgery, chemotherapy, and radiation and leads to changes in the affected woman. These patients may experience difficulties with changes in hormonal and sexual function (sexual inactivity or loss of sexual desire). Some patients may even repress their desire to have children due to a cervical cancer diagnosis.27
Considering these changes, it is not surprising that gynecologic cancer patients suffer from psychosocial restrictions. However, whether these restrictions are part of the disease itself or whether they are caused by therapy remains unknown. Regardless, the treatment for gynecologic malignancies focuses on the (physical) prolongation of life. Although studies have fortunately begun to focus on the QoL of affected female patients,28 little is known about these patients’ mechanisms of managing the disease (coping) or their resilience (among other aspects).
Finally, when considering other cancers, psychiatric symptoms such as depression and anxiety are one of the most prevalent cancer-related symptoms. The existence of these psychiatric disorders likely influences the prognosis of the underlying disease by affecting the patient’s QoL or the success of the therapy.29 To address these objectives, we closely examined the incidence of attending psychiatric disorders in patients with different types of gynecologic cancer, especially cervical cancer, in comparison with the incidence in general cancer patients. We hope to identify possible gaps in the literature. Furthermore, the findings should provide a foundation for future research in this field and should enhance the understanding of the psychosocial situation of women with gynecologic malignancies.
In conclusion, the central objectives that motivated this paper were as follows:
- to summarize the relevant literature on attending psychiatric disorders in a gynecologic cancer population;
- to identify the predictors, associated factors, and prevention strategies of psychiatric disorders;
- to present the current knowledge on psychiatric symptoms in a population with recurrent gynecologic cancer;
- to describe the limitations of the literature and identify future research areas; and
- to enhance the development and implementation of earlier and better diagnoses in the long term.
In this review, we systematically identified and evaluated the literature concerning our research questions. We used the search engines PubMed and Google Scholar to identify relevant publications. Our search included the keywords “gynecologic cancer”, “genital/cervical cancer”, “cervical cancer”, “psychiatric disorders”, “depression”, “anxiety”, “quality of life”, “coping”, “recurrence”, and “resilience” in different combinations. The references of the chosen publications were also examined to identify additional relevant studies.
This web-based literature search was conducted independently by two of the authors (HHOM, SK) in December 2016 and January 2017. The exclusion/inclusion criteria and selected publications were determined by all of the other authors according to the Cochrane recommendations and with regard to the relevance of the literature to the topic of this mini-review.
In total, 106 studies that matched the screening criteria were evaluated, and the studies reported in this review were selected from this initial sample. The studies were evaluated individually and comparatively among themselves or in the context of the current literature.
The studies provided different observations and reports of attending psychiatric disorders in gynecologic cancer patients with a primary focus on including studies with female genital/cervical cancer patients. The publication period of all studies was 1992–2016. These publications predominantly utilized prospective questionnaire-based methods (either self-administered or interviewer-administered) and are also discussed from that methodological perspective. An overview of relevant studies is provided in Tables 1 and 2.

Occurrence of psychiatric disorders
We closely examined the prevalence of depression and anxiety disorders in cervical cancer patients and then compared these results with the prevalence in other types of gynecologic cancer. Next, other components such as QoL, self-esteem/self-confidence, and coping mechanisms were evaluated.
In terms of depression and anxiety as attending psychiatric symptoms in patients with cervical cancer, most of the studies showed comparable results.
In 1992, Corney et al examined 138 women with cancer of the cervix and vulva to gain insight into their psychosocial adjustment after major gynecological surgery.30 These authors used the Hospital Anxiety and Depression Scale (HADS), which is a screening test for mild forms of psychiatric disorders, and conducted further interviews on self-esteem/self-confidence and self-perception of physical attractiveness. The HADS showed that 41% of the women were either doubtful (with a cut-off of 8 points) or definite (with a cut-off of 11 points) cases.
Similar results were demonstrated by Kim et al using the same questionnaire (eg, the authors showed a prevalence of anxiety of 39.5% and a prevalence of depression of 34.6%).31 The highest prevalence of depression and anxiety disorders was reported by Yang et al (HADS, prevalence 52.2%).32
Klee et al,33 observed a sample over time (up to 24 months) using the Center for Epidemiologic Studies Depression Scale and the Profile of Mood States questionnaires and found a decrease after 6 months from the initially high scores for depression and worry to the lower scores of the control group. Bradley et al conducted a follow-up over 5 years and showed the same results.
Other studies used other questionnaires (Spielberger State Trait Anxiety Inventory, Beck Depression Inventory) but obtained the same results (Cull et al [33% prevalence of depression] and Lau et al [37% prevalence of depression and anxiety]).35,36
When examining other gynecologic cancers such as ovarian cancer, Bodurka-Bevers et al37 found a 21% prevalence of depression and a 29% prevalence of anxiety in 2000. In 2004, Fowler et al examined gynecologic cancer patients (not specifically defined) from a national cancer institute and showed a 42% prevalence of depression and a 30% prevalence of anxiety.38
The only study with lower values for the prevalence of depression was conducted by Hengrasmee et al.39 These authors found a prevalence of depression in gynecologic cancer patients of 13.4%, which is lower than the lifetime prevalence of depression in the general population of 16%–20%;40–43 these authors proposed that the different types of psychological instruments administered (they used the Health-Related Self-Report questionnaire) could have been responsible for the lower results obtained. A study conducted by Jacob et al44 also found slightly lower rates of depression and anxiety in genital/cervical cancer patients.
Regarding other components, such as QoL, a study by Distefano et al45 showed that locally advanced cervical cancer patients had lower QoL scores than not only the general population but also patients with ovarian, endometrial, and other cancers. In 2000, Klee et al33 described the psychological and social reactions of 118 women with advanced-stage cervical cancer and found similar results. Regarding coping mechanisms, the patients’ coping abilities seemed nearly stable.
Bradley et al34 showed that QoL improved over time and did not significantly differ from that of healthy women after 5 years, although cervical cancer survivors more frequently reported a negative mood (dysphoria, anger, and confusion). Comparisons between endometrial and cervical cancer survivors showed that endometrial cancer survivors exhibited better social well-being and social functioning.34
Additionally, Corney et al30 assessed self-esteem/self-confidence and self-perception of physical attractiveness in their sample and found that more than half of the women felt the same as before their operations; however, 30%–40% felt that there had been negative changes.
Furthermore, these authors asked the patients about when they had experienced the most distress; this period seemed to coincide with the period of the most uncertainty (between the first medical indication and the diagnosis or between diagnosis and surgery).
Interestingly, life stress, depressive symptoms, and QoL prior to surgery were not associated with all-cause mortality according to Telepak et al.46
Finally, Ye et al47 obtained similar conclusions in their review concerning the treatment outcome of cervical cancer patients; specifically, QoL and sexual function were reduced in cervical cancer patients compared to the general population and should be treated with higher priority.
Predictors, associated factors, and prevention strategies
The examination of the possible predictors and associated factors of attending psychiatric disorders highlighted three factors in particular because of their association with poorer outcomes of cervical cancer patients:
- physical symptoms,
- lower socioeconomic status,
- sexual inactivity.
More precisely, the most reported physical symptoms were fatigue, gynecologic/menopausal symptoms, and pain.31,35,36,38 A lower socioeconomic status implies a low income, potentially unemployment, and a lower education level, which act as risk factors for depression in cancer patients.31,34,39,45 In regards to sexual inactivity, Cull et al showed that in their sample of 83 women, 61 were sexually active before the diagnosis, while almost half of the subjects reported deterioration in sexual function after cancer treatment;35 similar findings were reported in three other publications.30,31,36
Furthermore, one more factor was mentioned by three studies. Fowler et al,38 Bradley et al,34 and Corney et al30 found a link between the absence of a partner or the breakdown of a relationship and the occurrence of psychiatric disease.
Finally, some additional factors seemed to have minor significance but were mentioned nonetheless. These factors included age (younger patients [<50 years] were more likely to be depressed and had a lower QoL than older patients),36,37 poor performance status (which quantified cancer patients’ general well-being and activities of daily life),37,39 history of psychiatric illness,36 ethnicity, and language (Spanish-speaking Latinas seemed to be a particularly vulnerable group, potentially due to their socioeconomic status).48
Therefore, these factors could be predictors of attending psychiatric disorders; these findings are interesting because they were not specifically identified in general cancer studies49,50 but may indicate particularly vulnerable groups.
After analyzing different studies, we found no evidence of a connection between the treatment modality (eg, surgery and radiation) or complications over time (eg, post-operative) and the occurrence of psychiatric disorders;34,35,45 this finding is consistent with those of other cancer studies.12,13
Yang et al32 found that prevention strategies such as increasing hope, optimism, and general self-efficacy were positive influencing variables. These three variables as a whole showed even stronger predictive value than each one alone, potentially indicating that an integrated measure of multiple variables may be more realistic and effective than an individual construct.
Telepak et al46 found that greater use of active coping prior to surgery was related to a lower probability of all-cause mortality; however, it is important to consider that the use of different coping strategies depends on the patient’s cultural background,48 and thus we cannot specify a certain strategy.
Petersen and Quinlivan51 examined the effect of counseling and a relaxation intervention in patients with gynecologic cancer. These authors interviewed patients using the HADS and the General Health Questionnaire-28 and found that the intervention (conscious breathing, body scans, progressive muscle relaxation, and guided imagery) was associated with a significant reduction in the total scores of both questionnaires.
Psychiatric disorders in a population with gynecologic cancer recurrence
Thornton et al52 conducted a qualitative study of coping with recurrence in breast and gynecologic cancer patients. The patients participated in an individual or a group interview, and the authors observed notable differences in their responses to the initial diagnosis as opposed to the recurrence.52 The most important themes discussed were as follows:
- occurrence of depressive symptoms,
- decreased size of social networks (with passing years),
- additional losses from the erosion of social support networks.
In another study, the authors developed a psychological intervention for women with cancer recurrence and assessed independent variables (eg, hope and mindfulness) and psychological outcomes (eg, depression, negative mood, worry, and symptoms of generalized anxiety disorder) pretreatment and after 2, 4, and 7 months.53 The results showed that the negative factors (distress, anxiety, and negative affect) decreased, whereas the positive factors (positive affect, mental health-related QoL, hope, and mindfulness) increased over the course of treatment.
To summarize, patients with gynecologic malignancies, such as cancer of the cervix, clearly show an increased risk of attending psychiatric symptoms, mainly depressive mood alterations. The main limitation of this review, which in some aspect is caused by methodology, is that it only included a small number of papers that specifically addressed psychologic impairments other than somatic symptoms. Therefore, the cervical cancer population should first be compared to other gynecologic cancer populations using one consistent (prospective) study design, which should compare those diagnosed with ovarian or endometrial cancer to matched patients with breast cancer, as the most common type of cancer in females. The scores should integrate self-reported and interview-based ratings as direct clinical diagnoses to obtain robust results.
Larger sample sizes and comparable results regarding the mentioned impairments are needed in these populations. The prevalence of depression among cervical cancer patients ranges from 33%–52%, and this rate among other gynecologic cancer populations is approximately 21%. To interpret these results, it could be useful to consider the following numbers: the prevalence of depression in the general population at any point in the past 12 months is 7.7%–17.6%;54 therefore, the rates of depression are at least two times higher in the examined group than in the general population, emphasizing the need for extensive depressive/anxiety screening in cervical cancer patients.41
Regarding QoL, the lowest scores were also reported to occur in the cervical cancer population,45 and social well-being and social functioning also seemed to be worse in patients with cervical cancer than in those with other gynecologic cancers. These results indicate that women diagnosed with cervical cancer may be especially vulnerable, eg, due to lifestyle factors associated with the epidemiology of this cancer (younger age, absence of a partner, and lower educational level). This finding supports the need for systematic examinations, as previously discussed in this context. The high rates of comorbid anxiety (anxiety disorder itself and not situation-specific fears) and depression in genital/cervical cancer patients, ranging from 33%–45%, are also much higher than the rates in the normal population (rates reported up to 15%).55–57
QoL can improve over time in gynecologic cancer patients and increase to that of healthy women;34 however, the results indicate significant room for improvement with a variety of therapeutic and psychosocial approaches such as social support and psychological intervention. Effective, validated psychosocial approaches and interventions for other types of cancer are well known. However, only a few studies have addressed the preliminary results on the effects of these interventions in genital/cervical cancer patients, and the current findings cannot be safely interpreted to indicate effectiveness because of the non-comparable intervention types or the therapeutic goals that did not persist in follow-up examinations.58–63
Comorbid patients tend to have severe symptoms, poorer outcomes, and greater use of health care resources than those with a single disorder. Furthermore, these patients have a higher suicidal risk; therefore, it is very important to detect and treat both disorders.64,65
Additionally, certain factors have been shown to predict the onset of attending psychiatric disorders. Therefore, certain high-risk patient groups (lower socioeconomic status, sexual inactivity, and/or absence of a partner) are especially in need of screening programs for psychiatric co-therapy. Furthermore, patients in groups classified as high risk, which is a negative predictor of lower psychosocial outcome, should receive special psychological support before an attending psychiatric disorder can occur.
Finally, patients suffering from recurrent gynecologic cancer warrant particular attention because of their reports of increased depressive symptoms, which are much greater compared with the common population1,2 and comparable to cancer patients, and of concomitant impairments such as reduced social networks and additional losses from the deterioration of their social support network.
The small number of studies included in this analysis is certainly a major limitation, but the findings provide a foundation for further research in this field.
Recommendation for future research
Extending the research approaches reported here to other fields, such as attending psychiatric disorders in patients with precursors of gynecologic cancer, is highly recommended.
In the future, more studies are needed concerning the epidemiology, patho-mechanisms, and treatment of different psychiatric disorders in patients with gynecologic cancer, especially in under-recognized patients with genital/cervical cancer. In this context, differentiation between the applied therapeutic and psychosocial interventions is also needed.
Moreover, it would be interesting to explore different coping mechanisms and then assess the regular, systematic coping strategies or interventions in these women. Little research has been conducted concerning the resilience of these patients. Thus, it would be useful to identify the deficits in the resilience structure of patients with gynecologic cancer to offer better support.
Therefore, future research should establish standardized and regular screening programs for psychiatric disorders in gynecologic cancer patients, especially after each genital/cervical cancer diagnosis, given the limited data concerning psychologic alterations in this group of patients.
These screening programs should include standardized screening questionnaires distributed regularly by gynecologists after a genital/cervical cancer diagnosis to patients in the specific reported high-risk subgroups (those with imminent depressive symptoms, diminished social networks and social support, physical symptoms concurrent with the disease, sexual inactivity, or low socioeconomic status). Patients who screen positive should be further assessed using a clinical interview to determine whether a psychiatric diagnosis is warranted and, if appropriate, to provide specialized treatment to improve the psychosocial outcome of these patients.
