The coronavirus disease caused by the SARS- CoV-2 Virus, announced in early 2020, killed 600,000 people in one year ( 1 ). The coronavirus not only resulted in a high mortality disease, but it caused social functioning changed and view of health in all areas of life entirely ( 2 , 3 ). As the process progresses, the increasing morbidity and mortality of Covid-19, which is associated with many diseases, has led to changes in the understanding of medicine ( 4 , 5 ). Some Covid- 19 preventive practices were implemented by the scientific committee established in our country ( 6 , 7 ). Some of these included: the constant wearing of masks, social distancing restrictions, no crowded meetings, limiting the number of stores, and temporary closure of restaurants ( 8 , 9 ). In hospitals, regulations such as visitor restriction, reduction in elective surgery,removal of systemic treatment, change of chemotherapy regimens, extension of intervals between cycle and implementation Üof teleconsultations were introduced ( 10 ). Although these measures proved very beneficial and reduced the number of infected individuals, with Covid-19 mortality, many patients with cancer had to change places where they received systemic treatment, resulting in varying proportions of anxiety ( 11 ). According to recent studies, the pandemic has been shown to cause various mental changes such as intense posttraumatic stress, depression, insomnia, fear, and anxiety that reduce patients' quality of life and adversely affect compliance with medical treatment ( 12 ). Especially the patients in the obstetrics clinics, which consisted of female patients, were significantly affected by the process ( 13 ). Cancer patients followed up in this patient group were also affected by the devastating effect of the Covid-19 process ( 14 ).

The study evaluates the relationship between anxiety and SARS-CoV-2-related anxiety in obstetrics & gynecology patients who received systemic anticancer therapy and did not receive any treatment through questionnaires measuring stress through different methods.

This non-invasive observational survey study was conducted between February 2017 and June 2021. The study was approved by the local ethics committee (date: 27/01/2021 - ID: 2021-01/908). This study was carried out in accordance with the Declaration of Helsinki.

All patients have signed a written consent for treatment and data analysis. The treatment has not been changed by the design of this study. Eligible patients at the obstetrics clinic were selected from adults 18 years of age and older with histopathologic confirmation of malignant neoplasm who received systemic oncological therapy and at least one treatment cycle during the study. Patients who could not complete the questionnaires on their own and those with an unclear diagnosis of psychiatric disorders were excluded from the study. Demographic and clinical data such as age, gender, type of cancer, and type of treatment were collected from the patients' medical histories. Patients were asked to participate in the STAI-1, 2, C19S, and DT questionnaires to measure their fear/anxieties about the SARS-CoV-2 corona virus. Chemotherapy (CT) and Radiotherapy (RT) were recorded and analyzed for each.

The questionnaire we describe here, in a cohort of participants with healthy and with cancer who received anticancer treatment for different cancer types in gynecology clinics, examined the course of anxiety and fear symptoms and quality of life compared to the treatments they received during the SARS-CoV-2 pandemic. Consistent with our hypothesis, we found evidence of a clinically significant increase in mental health symptoms and a clinically significant increase in anxiety values in the cancer and healthy patient groups. Therefore, cancer patients were affected in terms of mental health and anxiety values during the pandemic.

According to the results of some individual studies, a high prevalence of depressive symptoms,anxiety and stress were encountered during the pandemic ( 19 ). However, meta-analyses analysis of Ayubi et al. and Yu et al. showed lower anxiety in patients who encountered with Covid-19 ( 20 , 21 ). The meta-analysis of Robinson et al. found an increase in mental health symptoms shortly after the pandemic, which then decreased ( 22 ). According to Pinkman et al., the impact of events related to COVID-19 on mental health may need time ( 23 ). Our study progressed with 3 questionnaires and, in agreement with the majority of the literature, anxiety increased in all who had Covid-19. During the pandemic process, both gender and age factors affected the health-related behaviors and preferences of individuals. In the study of Yildirim et al. ( 24 ), and Moccia et el. ( 25 ) reported higher depression and anxiety levels in female patients. Of course, the population of this study was predominantly female, and the difference may be related to the fact that women are disadvantaged in terms of social freedom or carry a heavy burden in terms of domestic responsibilities. In the study conducted in numerical equality, Özdin et al. found the anxiety about the pandemic to be higher in women ( 26 ). Furthermore, elderly patients preferred to postpone their appointments for a while and stay at home. Zhao et al. showed that anxiety and mental disorders are more intense in areas where quarantine practices are in place ( 27 ). 302 patients participated in our survey, with a wide range of ages. 21.2% of the patients had a diagnosis of Covid-19, while 6.6% died from Covid-19. Twenty-one of the patients were receiving psychiatric medication. Merz et al. stated that sociodemographic characteristics of cancer patients, such as education and age, affect their anxiety levels more than disease-related characteristics, and stated that low education level is associated with high anxiety levels of cancer patients during the pandemic ( 28 ). But, according to our results, education, chronic illness, psychological drugs, and age did not affect anxiety scores.

The study of Hacimusalar et al. have shown that not only female gender but also carrying a chronic disease are risk factors for anxiety during the pandemic( 29 ). Treatment processes, which are especially important for cancer patients, are negatively affected by their effects on anxiety ( 30 , 31 ). Although uncertainties, such as the variable restrictions imposed by COVID- 19, cause anxiety and fear for cancer patients, studies on its psychological effects for these patients are limited. Baffert et al. investigated COVID-related anxiety in cancer patients and found a reduction in anxiety levels after quarantine ( 32 ). A study by Sigorski et al., in his study of 306 patients with breast cancer, reported that being under 65, female, and having breast cancer was associated with the highest levels of anxiety. It also reported that cancer-related anxiety was higher than COVID-related anxiety ( 33 ). In our study, cancer was diagnosed in 59.3% according to the affected regions: 20.1% endometrium, 47.5% breast, 18.4% ovary, 12.8% cervix, and 1.2% uterus. Cancer significantly affected STAI-1, STAI-2 C19S, and DT. Patients with cancer had 1.39-fold higher STAI-1 scores than those without cancer. Similarly, patients with cancer had 1.37 times higher STAI-2 than patients without cancer. In the analysis for C19S score, cancer had 1.41 times higher C19S than patients without cancer. For DT scores, this ratio was 1.65 times.

The STAI-1 scores of the patients who received CT were 1.16 times than the STAI-1 scores of the patients who had cancer but did not receive additional tx. STAI-1 scores of the patients who received RT were 1.13 times the STAI-1 scores of the patients who had cancer but did not receive additional tx is higher (p<0.001). The STAI-1 scores of patients who received CT+RT were 1.18 times more elevated than the STAI-1 scores of patients who had cancer and did not receive additional tx. The STAI-2 scores of patients with cancer who received CT+RT treatment were 1.14 times higher than patients with cancer who did not receive treatment. RT and CT had no effects on STAI-2 scores. The C19S of cancer patients who received CT, RT, and CT+RT were higher than those who did not receive treatments. The C19S of the patients who received CT were 1.22 times than the C19S of the patients who had cancer but did not receive additional tx. C19S of patients who received LT+RT were 1.26 times higher than the C19S of patients who had cancer but did not receive additional tx.

The strongest aspect of this study is that it is a unique and the detailed survey to analyze the Covid-19 impact with anxiety change. It had several limitations, especially due to the fact that it was research conducted during the pandemic. The most important limitation was that the study was conducted in only one hospital and did not include a control. It did not allow us to investigate changes in the pre-pandemic period, as it did not include baseline data before COVID-19. Although we added the groups that did not have covid-19, some patients had the disease without being diagnosed with covid-19 and we could not certain that issue. Second, the hospital where the study was conducted may differ from COVID-19 death rates around the world. Finally, we conducted the surveys in predetermined time periods and decisions can be affected by situational factors.

Cancer patients have been subject to a strong challenge in the care of mental health symptoms during the pandemic. According to our study, cancer patients were affected by this condition for anxiety, and therefore clinicians should remain vigilant for mood complications.
