Impact of the COVID-19 epidemic at a high-volume facility in gynecological oncology in Tokyo, Japan: a single-center experience

Predictors of treatment failure for adenocarcinoma in situ of the uterine cervix: Up to 14 years of recorded follow‑up

The incidence of adenocarcinoma-in-situ (AIS) of the uterine cervix is rising, with invasive adenocarcinoma becoming increasingly common relative to squamous cell carcinoma. The present study reviewed a cohort of 84 patients first-time treated by conization for histologically-confirmed AIS from January 2001 to January 2017, to identify risk factors associated with recurrent/persistent AIS as well as progression to invasive cervical cancer. Nearly 80% of the patients were age 40 or younger at conization. Endocervical and ectocervical margins were deemed clear in 42 of the patients. All but two patients had ≥1 follow-up, with post-conization high-risk human papilloma virus (HPV) results documented in 52 patients. Altogether, 12 histopathologically-confirmed recurrences (14.3%) were detected; two of these patients had microinvasive or invasive carcinoma. In three other patients cytology showed AIS, but without recorded histopathology. Eight patients underwent hysterectomy for incomplete resection very soon after primary conization; they were not included in bivariate or multivariate analyses. Having ≥1 post-follow-up positive HPV finding yielded the highest sensitivity for histologically-confirmed recurrence: 87.5 [95% confidence interval (CI) 47.4-99.7]. Current or historical smoking status provided highest specificity: 94.4 (95% CI 72.7-99.9) and overall accuracy: 88.0 (95% CI 68.8-97.5) for histologically-confirmed recurrence. With multiple logistic regression (MLR), adjusting for age at conization and abnormal follow-up cytology, positive HPV18 was the strongest predictor of histologically-confirmed recurrence (P<0.005). Having ≥2 positive HPV results also predicted recurrence (P<0.02). Any unclear margin yielded an odds ratio 7.21 (95% CI 1.34-38.7) for histologically-confirmed recurrence adjusting for age, but became non-significant when including abnormal cytology in the MLR model. The strong predictive value of HPV, particularly HPV18 and persistent HPV positivity vis-à-vis detected recurrence indicated that regular HPV testing for patients treated for AIS is imperative. In conclusion, furthering a participatory approach, including attention to smoking with encouragement to attend needed long-term follow-up, can better protect these patients at high risk for cervical cancer.

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.

Agent-Based Simulation of Virus Testing in Certain-Exposure Time through Community Health Service Centers' Evaluation-A Case Study of Wuhan

Short-term and large-scale full-population virus testing is crucial in containing the spread of the COVID-19 pandemic in China. However, the uneven distribution of health service facilities in terms of space and size may lead to prolonged crowding during testing, thus increasing the chance of virus cross-infection. Therefore, appropriate control of crowd exposure time in large-scale virus testing should be an important goal in the layout of urban community health facilities. This paper uses the Quanta concept and Wells-Riley model to define the "certain-exposure time" under low cross-infection rate. Then, an agent-based simulation model was used to simulate the reasonable screening efficiency of community health service facilities during certain-exposure time at different stages of the COVID-19 pandemic and under different screening processes. Eventually, the screening efficiency was evaluated for all community health service centers in Wuhan. During the early period of the pandemic, 23.13% of communities failed to complete virus testing of community residents within 2 h of certain-exposure time, leaving approximately 56.07% of the population unscreened; during the later period of the COVID-19 pandemic, approximately 53% of communities and 75% of residents could not be screened. The results can pinpoint the distribution of community health service centers with inadequate screening capacity, facilitate targeted policymaking and planning, and effectively curb COVID-19 cross-infection during screening.

Age, margin status, high-risk human papillomavirus and cytology independently predict recurrent high-grade cervical intraepithelial neoplasia up to 6 years after treatment

The present study aimed to identify the factors that independently contribute to disease recurrence among women first-time treated for high-grade cervical intraepithelial neoplasia (CIN) during 4–6 years of follow-up. Overall, 529 of 530 eligible patients participated; these patients all attended a 1st follow-up appointment ~6 months post-conization, at which time high-risk human-papillomavirus (HPV) testing, liquid-based cytology and colposcopy were performed. Full data on margin excision status, other aspects of initial treatment and comorbidity were obtained. At least one subsequent follow-up was attended by 88% of patients. A total of 22 recurrent cases were detected during follow-up. Detected recurrence was the outcome of focus for multiple logistic regression analysis, with odds ratios (OR) and 95% confidence intervals (CI) computed. Four significant independent risk factors were identified: Age 45 years or above (OR=3.5, 95% CI=1.3–9.9), one or both unclear or uncertain margins (OR=5.3, 95% CI=2.0–14.2), positive HPV at 1st follow-up (OR=5.8, 95% CI=2.0–16.8), and abnormal cytology at 1st follow-up (OR=3.9, 95% CI=1.4–11.0). Bivariate analysis revealed that persistent HPV positivity was associated with recurrence (P<0.01). These findings indicated that incomplete excision of the CIN lesion may warrant more intensive subsequent screening, regardless of early post-conization HPV findings. Although early post-conization positive HPV was a powerful, independent predictor of recurrent high-grade CIN, over one-third of the patients with detected recurrence had a negative early post-conization HPV finding. These patients returned for routine screening, at which time, in most cases, HPV status was positive, thus indicating the need for repeated HPV evaluation. Especially during the on-going pandemic, home vaginal self-sampling is recommended. Particular attention is required for women aged ≥45 years. In addition, although not statistically significant, relevant comorbidities, especially autoimmune conditions, warrant consideration in clinical decision-making. Women who have been treated for high-grade CIN are at risk for recurrent disease and progression to cervical cancer; therefore, they require careful, individualized follow-up to avoid these adverse consequences.

Qualitative Interdisciplinary Learning Reviews of Non-COVID-19 Patients' Journeys During the COVID-19 Pandemic

In the early months of 2020, hospital processes were changed in response to the coronavirus disease 2019 (COVID-19) pandemic. We present one community hospital's experience in conducting a series of interdisciplinary learning reviews (ILRs) on non-COVID-19 patient's journeys during the early months of the pandemic. An ILR is a method of reviewing medical records using a system lens to identify system-level opportunities for improvement. Using the ILR method, we identified several opportunities for improvement in caring for our patients.

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.

Experiences of women with ovarian cancer during the COVID-19 pandemic: Examining intolerance of uncertainty and fear of COVID-19 in relation to psychological distress

PURPOSE

Our research aimed to examine the role of intolerance of uncertainty (IU) in psychological distress (PD) among women with ovarian cancer. Fear of COVID-19 (FCOV) was examined as a mediator, and participant health status and the reopening status of their geographic region were examined as moderators.

DESIGN

A cross-sectional quantitative design was employed.

PARTICIPANTS

Participants (n = 100) were recruited through various online sources and completed the study via Qualtrics.

METHODS

Moderated mediation models and post-hoc linear regression analyses were used to determine the role of predictor variables in PD.

RESULTS

No significant moderators or mediators were found. Despite a strong correlation between FCOV and IU, both variables explained unique variance in the anxiety and stress models, while FCOV was not significant in the depressive symptoms model.

IMPLICATIONS FOR PROVIDERS

Both IU and FCOV should be considered in helping women with ovarian cancer manage their PD during the COVID-19 pandemic.
