In silico designed mRNA vaccines targeting CA-125 neoantigen in breast and ovarian cancer.

Somatic mutation-derived neoantigens are associated with patient survival in breast and ovarian cancer. These neoantigens are targets for cancer, as shown by the implementation of neoepitope peptides as cancer vaccines. The success of cost-effective multi-epitope mRNA vaccines against SARS-Cov-2 in the pandemic established a model for reverse vaccinology. In this study, we aimed to develop an in silico pipeline designing an mRNA vaccine of the CA-125 neoantigen against breast and ovarian cancer, respectively. Using immuno-bioinformatics tools, we predicted cytotoxic CD8+ T cell epitopes based on somatic mutation-driven neoantigens of CA-125 in breast or ovarian cancer, constructed a self-adjuvant mRNA vaccine with CD40L and MHC-I -targeting domain to enhance cross-presentation of neoepitopes by dendritic cells. With an in silico ImmSim algorithm, we estimated the immune responses post-immunization, showing IFN-γ and CD8+ T cell response. The strategy described in this study may be scaled up and implemented to design precision multi-epitope mRNA vaccines by targeting multiple neoantigens.

Treatment delay and treatment pattern modifications among epithelial ovarian cancer patients during the COVID-19 pandemic: A retrospective cohort study.

BACKGROUND AND OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic disrupted healthcare access and medical treatment, including oncological care. Treatment delay in ovarian cancer could impact survival. We aimed to assess if there were delays and treatment changes in a cohort of epithelial ovarian cancer patients. METHODS: A retrospective cohort of epithelial ovarian cancer patients included cases diagnosed during the first 22 months of the COVID-19 pandemic in the state of Sao Paulo and those diagnosed in the 22 months preceding the outbreak. Time-to-treat was measured in days. In each group, surgery and chemotherapy proportions were assessed according to healthcare insurance status. RESULTS: A 56.2% reduction in epithelial ovarian cancer diagnosis was identified during the pandemic group compared to the prepandemic group; fewer patients were diagnosed in stage I (p < 0.01). Time-to-treat increased from 18.9 to 23 days (p < 0.01). Surgery in the public sector fell from 74.6% to 65.3% during the pandemic, compared to 87.1% to 68.8% in the private sector. CONCLUSION: There were fewer overall diagnoses, reduced stage I diagnosis, increased time-to-treat, and a reduction in the proportion of patients submitted to surgery. Brazil's public healthcare system demonstrated a higher resiliency to treatment change than the private sector.

Electronic patient-reported monitoring of symptoms during follow-up of ovarian cancer patients: a feasibility study.

BACKGROUND: Ovarian cancer patients require monitoring for relapse. Innovative follow-up methods are increasingly being explored. An electronic patient-reported outcome (ePRO) follow-up pathway was developed for women treated for ovarian cancer. This feasibility study explored patient acceptability and compliance. METHODS: A single-arm non-blinded prospective feasibility study was undertaken at two hospitals. Participants were women who had completed treatment for ovarian cancer whose clinician was happy for them to be monitored remotely. Automated 3-monthly reminders were sent to participants to complete an ePRO questionnaire and obtain blood tests. Participants were reviewed over the phone by their clinical nurse specialist instead of attending clinic-based follow-up. The primary outcome was compliance (expected ePRO completions/blood tests) across the 12-month study period. Secondary outcomes were recruitment, attrition, resource use, symptom severity/alerts and patient acceptability. RESULTS: Twenty-four women consented (50% consent rate), and 13 remained on study at 12 months. Seven women relapsed, 3 chose to withdraw, and 1 withdrew for other clinical reasons. ePRO compliance was high and consistent at 75-82%, although the two hospitals differed. Adherence to the clinical protocol was evident for blood tests and contacts with staff (fewer visits, more phonecalls compared to an earlier audit). End-of-study feedback indicated high patient satisfaction. CONCLUSIONS: Remote ePRO follow-up for ovarian cancer is feasible and acceptable to patients who are able and willing to participate. However, the low recruitment rate (ineligible + declined) indicate it is not suitable/acceptable to all patients immediately post-treatment. Further large-scale research and implementation work is required, especially in a post-COVID era. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT02847715 (first registered 19/05/2016).

Clinical research in ovarian cancer: consensus recommendations from the Gynecologic Cancer InterGroup.

The Gynecologic Cancer InterGroup (GCIG) sixth Ovarian Cancer Conference on Clinical Research was held virtually in October, 2021, following published consensus guidelines. The goal of the consensus meeting was to achieve harmonisation on the design elements of upcoming trials in ovarian cancer, to select important questions for future study, and to identify unmet needs. All 33 GCIG member groups participated in the development, refinement, and adoption of 20 statements within four topic groups on clinical research in ovarian cancer including first line treatment, recurrent disease, disease subgroups, and future trials. Unanimous consensus was obtained for 14 of 20 statements, with greater than 90% concordance in the remaining six statements. The high acceptance rate following active deliberation among the GCIG groups confirmed that a consensus process could be applied in a virtual setting. Together with detailed categorisation of unmet needs, these consensus statements will promote the harmonisation of international clinical research in ovarian cancer.

Resilience in the Face of Pandemic: The Impact of COVID-19 on the Psychologic Morbidity and Health-Related Quality of Life Among Women With Ovarian Cancer.

PURPOSE: The COVID-19 pandemic has created new challenges for ovarian cancer survivors. This study aims to evaluate the psychologic morbidity and alterations in medical care caused by the pandemic. METHODS: Advanced-stage ovarian cancer survivors at our institution were contacted for participation in a cross-sectional telephone-based quantitative survey study assessing pandemic-related psychologic morbidity. Psychologic domains using validated measures were explored: health-related quality of life (HRQOL; functional assessment of cancer therapy [FACT-G7]), anxiety (generalized anxiety disorder-7 [GAD7]), depression (Patient Health Questionnarie-2 [PHQ2]), global health Patient-Reported Outcomes Measurement Information System - Global Physical Health/Global Mental Health (PROMIS-GMH/GPH), resilience (brief resilience scale), and loneliness (English Longitudinal Study on Aging). Novel COVID-19 pandemic questions were drawn from a larger survey developed in our department. RESULTS: Fifty-nine percent (61 of 104) of contacted patients completed the survey. One quarter of respondents had high resilience, with only 10% reporting low resilience. Only one patient screened positive for depression, and two for anxiety. Increased loneliness was reported by 43% of respondents. Patients' overall HRQOL was good (median = 21; range = 6-28). Few patients experienced treatment delays, with only four experiencing chemotherapy interruption and two reporting surgical delays. Multiple regression analyses revealed that high FACT-G7 HRQOL was predicted by age > 65 years, high self-reported mental health, high resilience, and being off chemotherapy. Lower COVID-19 concern was predicted by recurrent cancer and high resilience. CONCLUSION: Despite the far-reaching impact of the COVID-19 pandemic, ovarian cancer survivors' HRQOL has been maintained. Older age, high resilience, high mental health, and being off chemotherapy predicted better HRQOL. Ovarian cancer survivors remain resilient in the face of the pandemic, and the support of clinicians to preserve this invaluable personal resource is critical for well-being.

The "collateral damage" of the war on COVID-19: impact of the pandemic on the care of epithelial ovarian cancer.

The covid-19 pandemic has impacted the management of non-covid-19 illnesses. Epithelial ovarian cancer (EOC) requires long-duration multidisciplinary treatment. Teleconsultation and shared care are suggested solutions to mitigate the consequences of the pandemic. However, these may be challenging to implement among patients who come from the lower economic strata. We report the disastrous impact of the pandemic on the care of EOC by comparing patients who were treated during the pandemic with those treated in the previous year. We collected the following data from newly diagnosed patients with EOC: time from diagnosis to treatment, time for completion of planned chemotherapy, and proportion of patients completing various components of therapy (surgery and chemotherapy). Patients treated between January 2019 and September 2019 (Group 1: Pre-covid) were compared with those treated between January 2020 and December 2020 (Group 2: During covid pandemic). A total of 82 patients were registered [Group 1: 43(51%) Group 2: 39(49)]. The median time from diagnosis to start of treatment was longer in group 2 when compared to group 1 [31(23-58) days versus 17(11-30) days (p = 0.03)]. The proportion of patients who had surgery in group 2 was lower in comparison to group 1 [33(77%) versus 21(54%) (p = 0.02)]. Proportion of patients who underwent neoadjuvant (NACT) and surgery were fewer in group 2 in comparison to group 1 [9(33%) versus 18(64%) p = 0.002]. Among patients planned for adjuvant chemotherapy, the median time from diagnosis to treatment was longer in group 2 [28(17-45) days, group 1 versus 49(26-78) days, group 2 (p = 0.04)]. The treatment of patients with EOC was adversely impacted due to the COVID-19 pandemic. There was a compromise in the proportion of patients completing planned therapy. Even among those who completed the treatment, there were considerable delays when compared with the pre-covid period. The impact of these compromises on the outcomes will be known with longer follow-up.

Challenges and opportunities for ovarian cancer management in the epidemic of Covid-19: lessons learned from Wuhan, China.

China and the rest of the world are experiencing an outbreak of the 2019 novel coronavirus disease (COVID-19). Patients with cancer are more susceptible to viral infection and are more likely to develop severe complications, as compared to healthy individuals. The growing spread of COVID-19 presents challenges for the clinical care of patients with gynecological malignancies. Ovarian debulking surgery combined with the frequent need for chemotherapy is most likely why ovarian cancer was rated as the gynecologic cancer most affected by COVID-19. Therefore, ovarian cancer presents a particular challenging task. Concerning the ovarian cancer studies with confirmed COVID-19 reported from large-scale general hospitals in Wuhan, we hold that the treatment plan was adjusted appropriately and an individualized remedy was implemented. The recommendations discussed here were developed mainly based on the experience from Wuhan. We advise that the management strategy for ovarian cancer patients should be adjusted in the light of the local epidemic situation and formulated according to the pathological type, tumor stage and the current treatment phase. Online medical service is an effective and convenient communication platform during the pandemic.

Adapting and avoiding coping strategies for women with ovarian cancer during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic has resulted in unprecedented challenges for people living with cancer, impacting not only physical health but psychological well-being. The psychological response affects the individual as well as the community and can persist long after the outbreak. We aim to assess coping strategies employed by women with ovarian cancer during the COVID-19 pandemic. METHODS: Women with a current or prior diagnosis of ovarian cancer completed an online survey which included a query about coping strategies during the COVID-19 pandemic. The survey was distributed from March 30th through April 13, 2020 through survivor networks and social media. RESULTS: Six hundred and three women visited the survey website during the study period and 555 (92.0%) completed the survey. Four hundred and eight (73.5%) provided information on coping strategies utilized during COVID-19. Among those who responded, the median age was 58 years (range 20-85) and 150 participants (40.8%) were undergoing active cancer treatment. Commonly utilized adaptive coping strategies included emotional support (159, 39.0%), self care (148, 36.3%), hobbies (139, 34.1%), planning (87, 21.3%), positive reframing (54, 13.2%), religion (50, 12.3%) and instrumental support (38, 9.3%). Many participants also relied on avoidance coping strategies including self distraction (111, 27.2%) and substance use (19, 4.7%). CONCLUSIONS: Most ovarian cancer survivors are using adaptive, problem-focused coping strategies during the COVID-19 pandemic, however many are practicing avoidance strategies as well. As coping mechanisms profoundly impact quality of life, oncology providers must assist patients in identifying coping strategies that optimize physical and psychological well-being.

Awareness and perceptions related to COVID-19 among cancer patients: A survey in oncology department.

INTRODUCTION: Today, COVID-19 pandemic is still the most critical problem in the global health agenda. Since the awareness of the public in general and particularly awareness of those with comorbidities, such as cancer, determine the rate of mortality, the primary goal of this study was to assess the knowledge, perceptions and attitude of the patients with cancer towards the COVID-19 pandemic. The secondary objective of this study was also to measure the effect of COVID-19 on cancer patients' ongoing treatments. METHODS: This study recruited 300 oncology patients through an outpatient community-based oncology clinic in one of the 30 major cities of Turkey, which had taken a lockdown at weekends during April 2020. A questionnaire measuring the knowledge, attitudes and preventive behaviour was completed by each patient either face-to-face or through telephone survey. RESULTS: In general, participants had a positive attitude towards protective measures. No delay for current cancer treatments or appointments has been observed in 98% of patients. More than half of the patients(52.3%) were using some kind of nutritional supplement to increase their body resistance. Nearly two-third of patients could not identify the three most common symptoms of COVID-19 (fever, cough, dyspnoea), and half of them were not aware of the routes of transmission (by contact and droplets). It was observed that patients with stage 1 cancer were tend to stay at home, while patients with stage 4 cancer were prone to leave their houses for the hospital at a higher ratio. The rate of people leaving houses was significantly higher for male patients and for patients with a university degree, whereas patients who were older than 65 were tend to go only to the hospital when they leave their houses. CONCLUSION: This study suggests that routine follow-up and guidance for cancer patients seems to provide significant benefit to increase the knowledge and awareness of patients with cancer.

ESMO management and treatment adapted recommendations in the COVID-19 era: gynaecological malignancies.

The rapid spread of severe acute respiratory syndrome coronavirus 2 infection and its related disease (COVID-19) has required an immediate and coordinate healthcare response to face the worldwide emergency and define strategies to maintain the continuum of care for the non-COVID-19 diseases while protecting patients and healthcare providers. The dimension of the COVID-19 pandemic poses an unprecedented risk especially for the more vulnerable populations. To manage patients with cancer adequately, maintaining the highest quality of care, a definition of value-based priorities is necessary to define which interventions can be safely postponed without affecting patients' outcome. The European Society for Medical Oncology (ESMO) has endorsed a tiered approach across three different levels of priority (high, medium, low) incorporating information on the value-based prioritisation and clinical cogency of the interventions that can be applied for different disease sites. Patients with gynaecological cancer are at particular risk of COVID-19 complications because of their age and prevalence of comorbidities. The definition of priority level should be based on tumour stage and histology, cancer-related symptoms or complications, aim (curative vs palliative) and magnitude of benefit of the oncological intervention, patients' general condition and preferences. The decision-making process always needs to consider the disease-specific national and international guidelines and the local healthcare system and social resources, and a changing situation in relation to COVID-19 infection. These recommendations aim to provide guidance for the definition of deferrable and undeferrable interventions during the COVID-19 pandemic for ovarian, endometrial and cervical cancers within the context of the ESMO Clinical Practice Guidelines.

Alternative management for gynecological cancer care during the COVID-2019 pandemic: A Latin American survey.

OBJECTIVE: To determine the acceptance rate of treatment alternatives for women with either preinvasive conditions or gynecologic cancers during the COVID-19 pandemic among Latin American gynecological cancer specialists. METHODS: Twelve experts in gynecological cancer designed an electronic survey, according to recommendations from international societies, using an online platform. The survey included 22 questions on five topics: consultation care, preinvasive cervical pathology, and cervical, ovarian, and endometrial cancer. The questionnaire was distributed to 1052 specialists in 14 Latin American countries. A descriptive analysis was carried out using statistical software. RESULTS: A total of 610 responses were received, for an overall response rate of 58.0%. Respondents favored offering teleconsultation as triage for post-cancer treatment follow-up (94.6%), neoadjuvant chemotherapy in advanced stage epithelial ovarian cancer (95.6%), and total hysterectomy with bilateral salpingo-oophorectomy and defining adjuvant treatment with histopathological features in early stage endometrial cancer (85.4%). Other questions showed agreement rates of over 64%, except for review of pathology results in person and use of upfront concurrent chemoradiation for early stage cervical cancer (disagreement 56.4% and 58.9%, respectively). CONCLUSION: Latin American specialists accepted some alternative management strategies for gynecological cancer care during the COVID-19 pandemic, which may reflect the region's particularities. The COVID-19 pandemic led Latin American specialists to accept alternative management strategies for gynecological cancer care, especially regarding surgical decisions.
