Radiation therapy for gynecologic malignancies during the COVID-19 pandemic: International expert consensus recommendations

Clinical outcomes of abbreviated high dose-rate brachytherapy in locally advanced cervical cancer: lessons from the COVID pandemic for high dose-rate fractionation

PURPOSE

To evaluate outcomes of cervical cancer patients treated with abbreviated high dose rate brachytherapy (HDR-BT) that used 2-implants and delivered 4-5 fractions over 7-12 days rather than 21-28 days.

MATERIALS AND METHODS

Patients with stage IB2-IVA cervical cancer, treated with external beam radiation (EBRT) ± chemotherapy followed by abbreviated MR/CT-based HDR-BT were included. The planning aim was to achieve > 70Gy equivalent doses in 2Gy (EQD210Gy) at Point A dose in patients undergoing intracavitary BT (ICBT) and > 85Gy EQD210Gy to the HRCTV in intracavitary-interstitial BT (IC-ISBT). The dose constraints to 2 cc of bladder, rectum and sigmoid were restricted to < 90Gy3, < 75Gy3 and < 75Gy EQD23Gy respectively.

RESULTS

From 2020 to 2022, 245 patients were treated with EBRT followed by MR/CT-based HDR-BT. Median OTT was 57 days. The median HRCTV volume was 35.5cc with higher HRCTV in MR than CT-based (42.3cc vs. 32.8cc). The median dose to Point-A, HRCTV-D90, B2cc, R2cc and S2cc for ICBT was 78.1, 86.2, 87, 70.2 and 70.4Gy respectively. For IC-ISBT cohort, the median dose to HRCTV-D90, B2cc, R2cc, and S2cc was 86.1, 88.6, 70 & 66.7Gy respectively. The 3-years local control, pelvic control, locoregional, disease free and overall survival was 90%, 88%, 83.7%, 75.5% and 85% respectively. Late ≥ grade III gastrointestinal and genitourinary toxicities were 7.3% and 1.6% respectively with marginally higher toxicity in CT based cohort.

CONCLUSION

Accelerated HDR-BT schedule of 2-implants 4-5 fractions is radiobiological iso-effective and clinically safe with comparable oncological outcomes and adverse events.

Impact of the COVID-19 Pandemic on Tumor Stage and Pathohistological Parameters of Vulvar Cancer

Background/Objectives: Vulvar cancer (VC) comprises a small fraction of female neoplasms with notable high-incidence clusters among German regions. Despite a proposed impact of nationwide lockdowns in response to the COVID-19 pandemic on oncological diseases, the effect on VC staging and tumor characteristics remains yet to be resolved; therefore, analyzing pathological data from patients with squamous cell VC pre-, during, and post-COVID in a high-incidence region may offer insights into potential epidemiological and clinical trends. Methods: We identified a total of 90 patients who were diagnosed at the Institute of Pathology, University Hospital Saarland, between 2018 and 2023, and defined three distinct cohorts: a pre-COVID cohort (2018-2019), a COVID cohort (2020-2021), and a post-COVID cohort (2022-2023). Histomorphological data were collected from the individual patient reports and statistically analyzed using Fisher's exact test or the Kruskal-Wallis test. Results: Although we found no statistically significant differences in age, T-stage, perineural infiltration, blood vessel infiltration, resection status, grading, or resection margin between our three cohorts, surprisingly, we determined a greater extent of lymphovascular infiltration (Fisher's exact test; p = 0.041), as well as deeper tumor infiltration depth (Kruskal-Wallis test; p < 0.001) before the COVID-19 pandemic. Furthermore, we did not identify any soft indications of abnormalities in patient care within our center (unchanged status of the resection margins across all three cohorts). Conclusions: Our results clearly do not support a negative affection of clinical or pathobiological characteristics of VC during or after the pandemic. However, final assessments regarding the pandemic's effect on VC require additional study approaches in various regions, preferably with future extended timeframes of a longer follow-up.

Impact of the COVID-19 pandemic on brachytherapy and cancer patient outcomes: A systematic review

PURPOSE/OBJECTIVE(S)

To assess the impact of the COVID-19 pandemic on the use of brachytherapy in patients with gynecologic and prostate cancers including treatment delays, increased burden of mortality, and associated clinical outcomes.

MATERIALS/METHODS

A comprehensive search of PubMed, Cochrane Library, CINAHL, Scopus, and Web of Science was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Databases were searched for studies published through September 2023 using MeSH terms and keywords related to "COVID and brachytherapy." Inclusion criteria included all studies reporting on the impact of COVID-19 on treatment delay, treatment omission, recurrence rates, and clinical outcomes in patients requiring brachytherapy for prostate or gynecologic cancers from December 2019 to September 2023. Data were extracted by two independent reviewers (LH, IV).

RESULTS

Of the 292 screened records, 10 studies (9 retrospective, 1 prospective single-arm exploratory noninferiority) were included. Hypofractioned regimens were the preferred approach in radiation treatment (RT) centers, with 6 of 10 studies noting shift towards hypofractionation. For cervical cancer, intracavitary brachytherapy was limited to 3-4 fractions, reducing personnel and patient exposure. Treatment delays influenced by COVID-19 ranged between 19% and 53% and treatment omissions ranged between 2% and 28%. These disruptions arose from factors such as patient fear of contracting COVID-19, COVID-19 infection, barriers to accessing care, and operating room closures. Three studies reported on a single-application (SA) rather than a multiple application (MA) approach for cervical cancer. They reported excellent local control, shorter overall treatment time at the expense of higher grade ≥2 vaginal, genitourinary, and gastrointestinal events. For cervical cancer patients, overall treatment time (OTT) was significantly impacted by COVID-19 as reported by 2 studies from India. OTT > 60 days occurred in 40-53% of patients.

CONCLUSION

This is the first systematic review to assess the impact of the COVID-19 pandemic on brachytherapy in patients with gynecologic and prostate cancers. Although many expert consensus recommendations have been published during the pandemic regarding radiation therapy, few studies evaluated its clinical impact on brachytherapy delivery and patient outcomes. The COVID-19 pandemic resulted in treatment delays, omissions in brachytherapy, and further adoption of hypofractionated regimens. Early results demonstrate that despite increased toxicities, local control rates with hypofractionated treatment are similar to standard fractionation. The impact of the pandemic on gynecologic and prostate cancers is yet to be determined as well as the long-term outcomes on patients treated during the lockdown period.

Hypofractionated Radiotherapy in Gynecologic Malignancies-A Peek into the Upcoming Evidence

Radiotherapy (RT) has a fundamental role in the treatment of gynecologic malignancies, including cervical and uterine cancers. Hypofractionated RT has gained popularity in many cancer sites, boosted by technological advances in treatment delivery and image verification. Hypofractionated RT uptake was intensified during the COVID-19 pandemic and has the potential to improve universal access to radiotherapy worldwide, especially in low-resource settings. This review summarizes the rationale, the current challenges and investigation efforts, together with the recent developments associated with hypofractionated RT in gynecologic malignancies. A comprehensive search was undertaken using multiple databases and ongoing trial registries. In the definitive radiotherapy setting for cervical cancers, there are several ongoing clinical trials from Canada, Mexico, Iran, the Philippines and Thailand investigating the role of a moderate hypofractionated external beam RT regimen in the low-risk locally advanced population. Likewise, there are ongoing ultra and moderate hypofractionated RT trials in the uterine cancer setting. One Canadian prospective trial of stereotactic hypofractionated adjuvant RT for uterine cancer patients suggested a good tolerance to this treatment strategy in the acute setting, with a follow-up trial currently randomizing patients between conventional fractionation and the hypofractionated dose regimen delivered in the former trial. Although not yet ready for prime-time use, hypofractionated RT could be a potential solution to several challenges that limit access to and the utilization of radiotherapy for gynecologic cancer patients worldwide.

A two-center experience: The impact of COVID-19 on two brachytherapy programs in Ontario - virtual care, service suspension and radiation therapy workflow

INTRODUCTION

Most brachytherapy (BT) procedures require general anesthesia and are therefore considered aerosol generating medical procedures (AGMPs). The COVID-19 pandemic impacted BT as services were prioritized by balancing the harm associated with COVID-19 infection versus the effect of delay of potentially curative treatment. This article summarizes the impact of the pandemic on BT programs in two cancer centers in a Canadian province.

METHODS

As part of a quality assurance project, a retrospective study was conducted for the first five months of the pandemic (March 1 to July 31, 2020). Chart review and COVID-19 related mitigation strategies were identified by BT Clinical Specialist Radiation Therapists (bCSRT) in each center using electronic medical records, departmental reports, policies and procedures.

RESULTS

Impact included start of virtual care (VC), shortened fractionation, suspension of services and workflow changes.  Both centers implemented VC strategies to reduce clinic visits: "same-day size and treat" strategy for post-operative endometrial cancer patients and virtual patient education for all patients. BT services that were suspended were low-dose-rate and high-dose-rate (HDR) prostate treatments (Center 1), lung and esophagus HDR treatments (Center 2).  Workflow changes that affected staff and patients in both centers included COVID-19 screening and the use of personal protective equipment. The centers were marginally different in workflow adjustments for AGMP procedures.  Those considered high-risk AGMP and low-risk cancer were suspended temporarily with alternate treatment strategies sought for some patients. Others had temporizing treatment such as androgen deprivation therapy to facilitate oncological safe deferral of procedures.

CONCLUSION

Both BT programs delivered treatment to most patients with minimal delays and cancellations, where feasible. Some of the pandemic workflow changes continued to the current state of the pandemic. Long-term follow-up is needed to assess the impact of COVID-19 and treatment interruptions on oncologic outcomes.

Effect of COVID-19 on Gynecologic Oncology Care: A Survey of Practicing Gynecologic Radiation Oncologists in the United States

Purpose

The COVID-19 pandemic has placed demands and limitations on the delivery of health care. We sought to assess the effect of COVID-19 on the delivery of gynecologic oncologic care from the perspective of practicing radiation oncologists in the United States.

Methods and Materials

An anonymous online survey was created and distributed to preidentified radiation oncologists in the United States with clinical expertise in the management of gynecologic patients. The survey consisted of demographic questions followed by directed questions to assess specific patterns of care related to the COVID-19 pandemic.

Results

A total of 47 of 96 invited radiation oncologists responded to the survey for a response rate of 49%. Fifty-six percent of respondents reported an increase in locally advanced cervical cancer with no similar increase for endometrial, vulvar, or vaginal patients. Most respondents (66%) reported a pause in surgical management, with a duration of 1 to 3 months being most common (61%). There was a reported increased use of shorter brachytherapy regimens during the pandemic. Most providers (61%) reported caring for at least 1 patient with a positive COVID-19 test. A pause or delay in treatment due to COVID-19 positivity was reported by 45% of respondents, with 55% reporting that patients chose to delay their own care because of COVID-19-related concerns. Total treatment times >8 weeks for patients with cervical cancer were observed by 33% of respondents, but occurred in >25% of patients.

Conclusions

Data from this prospectively collected anonymous survey of practice patterns among radiation oncologists reveal that the COVID-19 pandemic resulted in delays initiating care, truncated brachytherapy treatment courses, and a reported increase in locally advanced cervical cancer cases at presentation. These data can be used as a means of self-assessment to ensure appropriate decision making for gynecologic patients during the endemic phase of COVID-19.

Radiation therapy for vulvar cancer: consensus technical guidelines of the GINECOR working group of the Spanish Society of Radiation Oncology. Part 2: radiotherapy recommendations

PURPOSE

The present consensus statement was developed by the GINECOR working group on behalf of the Spanish Society of Radiation Oncology (SEOR). This document provides an up-to-date review of the technical aspects in radiation treatment of vulvar cancer.

METHODS

A two-round modified Delphi study was conducted to reach consensus on the appropriateness of technical aspects of external beam radiotherapy and brachytherapy. Three clinical scenarios were proposed: adjuvant treatment of vulvar cancer, radiation treatment of locally advanced vulvar carcinoma and locoregional recurrences. After the first round, an extensive analysis of current medical literature from peer-reviewed journal was performed to define evidence-based treatment options. In the second round, participants were asked to indicate their level of agreement with the preliminary recommendations according to the GRADE (Grade of Recommendation, Assessment, Development, and Evaluation) criteria, as follows: strongly agree; agree; neither agree nor disagree; disagree and strongly disagree.

RESULTS

The main recommendations on external beam radiotherapy and brachytherapy, both in adjuvant setting and local advanced disease are summarized. Recommendations include treatment technique, treatment volume, and doses in target and organs at-risk. Taking into consideration the different clinical scenarios of recurrent disease, the radiation treatment should be individualized.

CONCLUSIONS

In the absence of robust clinical data, these recommendations may help to select the optimal radiotherapy approach for this relatively rare cancer.

Early outcomes of abbreviated multi-fractionated brachytherapy schedule for cervix cancer during COVID-19 pandemic

PURPOSE

Brachytherapy (BT) for cervix cancer was listed as a level I priority and reduced number of implants and multiple fractions were recommended during COVID-19 pandemic. We present early clinical outcome of this approach.

METHODS AND MATERIALS

Patients treated with (chemo)radiotherapy and BT with single implant and multiple fractions BT were included. Treatment protocol included 3-5 fractions of 5-8.5 Gy with an aim to achieve point A dose of 70 Gy EQD2_10Gy (or HRCTV dose of >80 Gy EQD2_10Gy) in those undergoing intracavitary (IC) and HRCTV dose >85 Gy EQD2 10Gy in patients undergoing Intracavitary-Interstitial (IC/IS) whereas maintaining bladder (B2cc), rectum (R2cc), sigmoid (S 2cc) doses of 90, 75, and 75 Gy EQD2_3Gy. Time to event analysis was used to report oncological endpoints. Toxicity was reported using crude proportions.

RESULTS

From April 2020 to March, 2021, 64 patients with stage IB2-IV received single implant and multi-fraction BT after external radiation of 45 Gy/25 fractions/5 weeks. Only 76.7% (n = 49) received concurrent chemotherapy. Median overall treatment time (OTT) was 56 days (38-131 days). Overall, 62.5% (n = 40) patients received IC and 37.5% (n = 24) received IC+IS. The median HRCTV was 34.7 cc (IQR 25-41). Median (IQR) point A dose, HRCTV D90, B2cc, R2cc, and S2cc for those undergoing IC was 74 Gy (71-78), 80 Gy (73-84), 86 Gy (82-89), 70 Gy (65-74), 65 Gy (59-73) respectively. For the IC+IS cohort, HRCTV D90, B2cc, R2cc, and S2cc was 84 Gy (78-89 Gy), 89 Gy (86-92), 70 Gy (67-74), 68 Gy (59-76). At a median follow-up of 16 months (5-27) the 2-year local control, pelvic control, cause specific and overall survival was 88%, 85.3%, 92.2%, and 81.3% respectively. Late gastrointestinal and genitourinary grade ≥III toxicities were 14% and 1.5% each.

CONCLUSIONS

Abbreviated BT outcomes are encouraging for oncological outcomes despite delays in overall treatment time and omission of chemotherapy. Further mature follow up is needed.

From Alpha to Omicron: A Radiation Oncology Network's Biocontainment-Based COVID-19 Experience

Purpose

To develop the safest possible environment for treating urgent patients with COVID-19 requiring radiation, we describe the unique construction of negative air pressure computed tomography simulator and linear accelerator treatment vaults in addition to screening, delay, and treatment protocols and their evolution over the course of the COVID-19 pandemic.

Methods and Materials

Construction of large high-efficiency particulate air filter air-flow systems into existing ductwork in computed tomography simulator rooms and photon and proton treatment vaults was completed to create negative-pressure rooms. An asymptomatic COVID-19 screening protocol was implemented for all patients before initiation of treatment. Patients could undergo simulation and/or treatment in the biocontainment environments according to a predefined priority scale and protocol. Patients treated under the COVID-19 protocol from June 2020 to January 2022 were retrospectively reviewed.

Results

Negative air-flow environments were created across a regional network, including a multi-gantry proton therapy unit. In total, 6525 patients were treated from June 2020 through January 2022 across 5 separate centers. The majority of patients with COVID-19 had radiation treatment deferred when deemed safe. A total of 42 patients with COVID-19, who were at highest risk of an adverse outcome should there be a radiation delay, were treated under the COVID-19 biocontainment protocol in contrast to those who were placed on treatment break. For 61.9% of patients, these safety measures mitigated an extended break during treatment. The majority of patients (64.3%) were treated with curative intent. The median number of biocontainment sessions required by each patient was 6 (range, 1-15) before COVID-19 clearance and resumption of treatment in a normal air-flow environment.

Conclusions

Constructing negative-pressure environments and developing a COVID-19 biocontainment treatment protocol allowed for the safe treatment of urgent radiation oncology patients with COVID-19 within our department and strengthens future biopreparedness. These biocontainment units set a high standard of safety in radiation oncology during the current or for any future infectious outbreak.

Covid-19 and radiotherapy: a systematic review after 2 years of pandemic

Introduction

Following the Covid-19 pandemic spread, changes in clinical practice were necessary to limit the pandemic diffusion. Also, oncological practice has undergone changes with radiotherapy (RT) treatments playing a key role.Although several experiences have been published, the aim of this review is to summarize the current evidence after 2 years of pandemic to provide useful conclusions for clinicians.

Methods

A Pubmed/MEDLINE and Embase systematic review was conducted. The search strategy was "Covid AND Radiotherapy" and only original articles in the English language were considered.

Results

A total of 2.733 papers were obtained using the mentioned search strategy. After the complete selection process, a total of 281 papers were considered eligible for the analysis of the results.

Discussion

RT has played a key role in Covid-19 pandemic as it has proved more resilient than surgery and chemotherapy. The impact of the accelerated use of hypofractionated RT and telemedicine will make these strategies central also in the post-pandemic period.

Impact of the First Wave of COVID-19 Pandemic on Radiotherapy Practice at Tata Memorial Centre, Mumbai: A Longitudinal Cohort Study

PURPOSE

Delivery of cancer care during the pandemic required adopting various changes in the standard management. We analyzed the impact of the first wave of the COVID-19 pandemic on radiation oncology treatment practices at Tata Memorial Hospital in India.

MATERIALS AND METHODS

From March 1 to October 31, 2020, all consecutive patients who attended the radiation oncology department for radiotherapy treatment were included in this study. Electronic medical records, patient files, and telephonic consult were used to collect patient's data including changes in the standard treatment practice, COVID-19 testing and its results, and subsequent impact on radiotherapy treatment. Comparison was done with the same period data of 2019 for the number of the caseload, radiotherapy regimen, referral rates, and noncompliance rates.

RESULTS

Our study included 4,256 patients with a median age of 52 years (interquartile range 41-61 years). There was a significant drop in the new-patient registrations (approximately 63%), radiotherapy consultations (44.9%), and referrals to other centers (27.8%). The reduction in the caseload was highest for genitourinary cases (-58.5%) and the lowest for breast cases (-11.5%) when compared with the 2019 cohort. Among those treated with radical intent, the noncompliance rate was 15%. Hypofractionation was the commonly adopted regimen across all sites. Compared with 2019, the maximum reduction in the average fractions per patient was seen in the breast cancer cases (-8.2 fraction), followed by genitourinary cases (-4.9 fraction). Of the 27.8% of patients tested for COVID-19, 13.4% turned positive and 3.4% died due to the disease.

CONCLUSION

The COVID-19 pandemic adversely affected the number of radiotherapy consultations and treatments at our institute. However, our department offered uninterrupted services despite grave challenges. Hypofractionated regimen was used across disease sites to minimize patient visits and allow planned treatment completion. Radiotherapy was delivered safely, and patients experienced low rates of COVID positivity during radiotherapy and even lower mortality.

Quality-of-Life Outcomes and Toxic Effects Among Patients With Cancers of the Uterus Treated With Stereotactic Pelvic Adjuvant Radiation Therapy: The SPARTACUS Phase 1/2 Nonrandomized Controlled Trial

IMPORTANCE

Adjuvant radiation plays an important role in reducing locoregional recurrence in patients with uterine cancer. Although hypofractionated radiotherapy may benefit health care systems and the global community while decreasing treatment burden for patients traveling for daily radiotherapy, it has not been studied prospectively nor in randomized trials for treatment of uterine cancers, and the associated toxic effects and patient quality of life are unknown.

OBJECTIVE

To evaluate acute genitourinary and bowel toxic effects and patient-reported outcomes following stereotactic hypofractionated adjuvant radiation to the pelvis for treatment of uterine cancer.

DESIGN, SETTING, AND PARTICIPANTS

The Stereotactic Pelvic Adjuvant Radiation Therapy in Cancers of the Uterus (SPARTACUS) phase 1/2 nonrandomized controlled trial of patients accrued between May 2019 and August 2021 was conducted as a multicenter trial at 2 cancer centers in Ontario, Canada. In total, 61 patients with uterine cancer stages I through III after surgery entered the study.

INTERVENTIONS

Stereotactic adjuvant pelvic radiation to a dose of 30 Gy in 5 fractions administered every other day or once weekly.

MAIN OUTCOMES AND MEASURES

Assessments of toxic effects and patient-reported quality of life (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires C30 and endometrial EN24) were collected at baseline, fractions 3 and 5, and at 6 weeks and 3 months of follow-up. Descriptive analysis was conducted, calculating means, SDs, medians, IQRs, and ranges for continuous variables and proportions for categorical variables. Univariate generalized linear mixed models were generated for repeated measurements on the quality-of-life scales.

RESULTS

A total of 61 patients were enrolled (median age, 66 years; range, 51-88 years). Tumor histologic results included 39 endometrioid adenocarcinoma, 15 serous or clear cell, 3 carcinosarcoma, and 4 dedifferentiated. Sixteen patients received sequential chemotherapy, and 9 received additional vault brachytherapy. Median follow-up was 9 months (IQR, 3-15 months). Of 61 patients, worst acute gastrointestinal tract toxic effects of grade 1 were observed in 33 patients (54%) and of grade 2 in 8 patients (13%). For genitourinary worst toxic effects, grade 1 was observed in 25 patients (41%) and grade 2 in 2 patients (3%). One patient (1.6%) had an acute grade 3 gastrointestinal tract toxic effect of diarrhea at fraction 5 that resolved at follow-up. Only patient-reported diarrhea scores were both clinically (scores ≥10) and statistically significantly worse at fraction 5 (mean [SD] score, 35.76 [26.34]) compared with baseline (mean [SD] score, 6.56 [13.36]; P < .001), but this symptom improved at follow-up.

CONCLUSIONS AND RELEVANCE

Results of this phase 1/2 nonrandomized controlled trial suggest that stereotactic hypofractionated radiation was well tolerated at short-term follow-up for treatment of uterine cancer. Longer follow-up and future randomized studies are needed to further evaluate this treatment.

Gynecologic radiation therapy in low and middle income countries during the COVID-19 pandemic

The COVID-19 pandemic has forever affected healthcare and posed an incredible challenge to our society to care for our sick. Patients with cancer were found early on to have higher rates of complications with COVID-19. Radiation therapy is an integral part of treatment for many types of gynecologic cancer and adaptation on its utilization during the pandemic varied across the globe. In this review, we detail certain guidelines for the use of radiation in gynecologic cancers during the pandemic as well as real world accounts of how different countries adapted to these guidelines or created their own based on individualized resources, staffing, government restrictions, and societal norms. Critically, this review demonstrates the breadth of fractionation schemes and technologies used when resources were limited but highlights the importance of long term follow-up for many of our patients during this time.

Increasing global accessibility to high-level treatments for cervical cancers

Human papillomaviruses (HPV)-related gynecological cancers are a major health care issue, and a leading cause of cancer death in low- and middle-income countries (LMIC). In 2020, the World Health Organization launched a program aimed at cervical cancer elimination, by screening and vaccination strategies. Offering the best possible care to women diagnosed with invasive cancer is a complementary objective. Treatment of cervical cancer as per modern standards is complex and multimodal, mainly relying on surgery, external-beam radiotherapy (+/-chemotherapy) and brachytherapy. In parallel with the pivotal role of multidisciplinary discussion, international societies provide guidance to define the most effective and least toxic anti-cancer strategy, homogenize treatment protocols and provide benchmark quality indicators as a basis for accreditation processes. The challenge is to offer the appropriate diagnostic workup and treatment upfront and to avoid non- evidence-based treatment that consumes resources, impairs quality of life (QoL), and compromises oncological outcome. Various strategies may be applied for improving treatment quality: development of surgical mentorship, companion-training programs and international cooperation. The lack of radiotherapy/brachytherapy facilities is a major concern in LMIC. Reinforcing international support in terms of education, training, research and development and technical cooperation with national projects is required to increase access to minimum requirements but also introduce modern techniques, upgrade radiotherapy/brachytherapy services, and expand access to modern systemic treatments. In countries with robust economies, compliance to standards should also be increased. Integrative cancer care and multidisciplinary approaches are needed to tackle the dual challenge of increasing cure rates while minimizing QoL impairment. Appropriate dimensioning of the resources to avoid harmful treatment delays and access to expert referral centers is also a priority.

COVID-19 and Gynecologic Oncology: What Have We Learned?

COVID-19 has transformed the care we provide to gynecologic oncology patients. In addition to directly impacting the diagnosis and treatment of women with gynecologic cancer, it has affected our patient’s ability to undergo recommended surveillance and has made an impact on every caregiver providing care during this time. Herein we review the current literature on the impact of COVID-19 on gynecologic oncology and highlight new approaches and innovations that have resulted in gynecologic cancer care as a result of the pandemic. The impact of COVID-19 on the field of gynecologic oncology has been profound. In addition to directly impacting the diagnosis and treatment of women with cancer, it has also challenged the very ethics with which we practice medicine. The equitable distribution of resources is paramount to upholding the Hippocratic Oath which we all invoke. The COVID-19 pandemic has stripped this oath down to its very core, forcing all medical practitioners to scrutinize who gets what resources and when. As the pandemic continues to unfold, the question remains — in the setting of a strained and overburdened healthcare system, how do we maximize beneficence to one group of patients, while maintaining non-maleficence to others? As gynecologic oncologists, we are responsible for advocating for our patients to ensure that the quality of their cancer care is not compromised, while also not overutilizing resources that are sorely needed for the care of COVID-19 victims, and not making them more likely to succumb to COVID-19 by the very nature of the treatment we provide. The effects of the pandemic are far-reaching and broad, and many of these are yet to be determined. Future studies are needed to analyze how the above-utilized strategies in GYN cancer care during the pandemic will impact the long-term outcomes of our patients.

Effect of COVID-19 Pandemic on Gynecological Cancer Radiation During Complete Nationwide Lockdown: Observations and Reflections From Tertiary Care Institute in India

PURPOSE

To report real-world compliance to radiation in gynecologic cancers during the complete lockdown phase of COVID-19 pandemic.

METHODS AND MATERIALS

From March 23, 2020, until June 30, 2020, complete lockdown was imposed in India. During this period there was restructuring of cancer care and radiation oncology department due to operational policies prevalent in the institution, and the care for gynecological cancer was based on the evolving international recommendations. Institutional review board approval was obtained to audit patterns of care during the complete lockdown phase. Descriptive variables were used to report on patient characteristics, compliance, delays, toxicity, and observed deviations in recommended care.

RESULTS

During the lockdown period spanning 100 days, treatment of 270 and telephonic follow-up of 1103 patients with gynecological cancer was undertaken. Of 270 new patients, due to travel restrictions, 90 patients were referred to the facilities in vicinity of their residence. Of the remaining 180 patients, 138 were planned for complete treatment at our institution and 42 were referred to our center for brachytherapy. Of 138 patients, only 106 (76%) completed the planned external radiation. Twenty-four (26%) patients completed full course of concurrent chemotherapy, 11 (12%) received chemotherapy dose reduction, and 57 (62%) received no concurrent chemotherapy. Treatment delay of up to 3 weeks was noted in 8.6% patients due to COVID-19 infection. No grade 4 to 5 acute sequelae were observed. No excess adverse effects were observed in high-risk population. Low rate of symptom burden was observed among 1103 patients on telephonic follow-up. With 100 (9.6%) patients reporting symptoms, among these, 54% (54 of 100) had complete resolution of symptoms within 4 weeks of teleconsultation, and 10% had disease progression.

CONCLUSIONS

Low compliance with planned treatment was observed for radiation and concurrent chemotherapy due to lockdown and fear of contracting COVID-19 and will likely lead to increased risk of cancer-related mortality. Rapid restructuring of care is needed to prevent the same as COVID-19 pandemic further evolves.

Patterns of care and outcomes of radiotherapy or hormone therapy in patients with medically inoperable endometrial adenocarcinoma

OBJECTIVE

The optimal treatment for medically inoperable endometrioid endometrial adenocarcinoma is unknown. The goal of this study was to evaluate the patterns of care and efficacy of radiotherapy (RT) or hormone therapy (HT) in the treatment of these patients.

METHODS

We performed a query of the National Cancer Database (NCDB) of patients with medically inoperable endometrioid adenocarcinoma of the endometrium diagnosed between 2004 and 2016 and treated with either RT or HT. A multivariate Cox regression model and propensity weighted analyses were used to evaluate overall survival after controlling for confounding variables. A multinomial logistic regression model was used to assess predictors of RT or HT use.

RESULTS

A total of 1036 patients were included in this cohort, and 73% (n = 759) were treated with RT alone. Patients who received definitive HT compared to RT were more likely to be older, diagnosed in the earlier years of this analysis, treated at lower-case volume centers, diagnosed with high-grade disease, or located outside of metropolitan areas. On multivariate analysis, treatment with HT alone versus RT alone was associated with significantly worse overall survival in the multivariate Cox model but not on propensity score weighted analysis. Interaction effect testing revealed that older patients and those treated at lower-volume centers had improved survival with RT compared to HT.

CONCLUSIONS

We identified factors associated with the receipt of RT or HT in medically inoperable endometrial cancer patients. Treatment with RT correlated with improved survival compared to HT in older patients and those treated at lower-volume centers.

COVID-19 Pandemic-Adapted Radiotherapy Guidelines: Are They Really Followed?

BACKGROUND

In our department, we provided guidelines to the radiation oncologists (ROs) regarding the omission, delay, or shortening of radiotherapy (RT). The purpose was to reduce the patients' exposure to the hospital environment and to minimize the departmental overcrowding. The aim was to evaluate the ROs' compliance to these guidelines.

METHODS

ROs were asked to fill out a data collection form during patients' first visits in May and June 2020. The collected data included the ROs' age and gender, patient age and residence, RT purpose, treated tumor, the dose and fractionation that would have been prescribed, and RT changes. The chi-square test and binomial logistic regression were used to analyze the correlation between the treatment prescription and the collected parameters.

RESULTS

One hundred and twenty-six out of 205 prescribed treatments were included in this analysis. Treatment was modified in 61.1% of cases. More specifically, the treatment was omitted, delayed, or shortened in 7.9, 15.9, and 37.3% of patients, respectively. The number of delivered fractions was reduced by 27.9%. A statistically significant correlation (p = 0.028) between younger patients' age and lower treatment modifications rate was recorded.

CONCLUSION

Our analysis showed a reasonably high compliance of ROs to the pandemic-adapted guidelines. The adopted strategy was effective in reducing the number of admissions to our department.

Radiotherapy based management during Covid-19 pandemic - A systematic review of presented consensus and guidelines

Treatment management of cancer patients in the radiation oncology departments during the current COVID-19 pandemic is challenging. A systematic review of published consensus/guidelines on the role of radiotherapy prioritization, suggested treatment protocols, and set up management was undertaken based on the PRISMA protocol and through PubMed/PMC, Scopus, Google Scholar, Web of Science databases until 01/20/2021. One hundred and sixty-eight publications or regional consensus were included. Summary of recommendations contained: (1) using hypo-fractionated (Hypo-F) regimens for therapeutic/palliative indications, (2) delaying radiotherapy for several weeks or until pandemic over, (3) omitting radiotherapy by replacement of alternative therapies or active surveillance, (4) applying safer patients' setup and preparation protocols, (5) developing telemedicine/telehealth service. To conclude, it is essential to carefully weigh the risk of exposure to COVID-19 infection and the benefit of treating cancer patients during the pandemic. Trying to have a global guideline facing this or any other probable crisis is crucial for health care service.

Palliative Radiotherapy for Advanced Cancers: Indications and Outcomes

Palliative radiotherapy (PRT) is well-tolerated, effective treatment for pain, bleeding, obstruction, and other symptoms/complications of advanced cancer. It is an important component of multidisciplinary management. It should be considered even for patients with poor prognosis, because it can offer rapid symptomatic relief. Furthermore, expanding indications for treatment of noncurable disease have shown that PRT can extend survival for select patients. For those with good prognosis, advanced PRT techniques may improve the therapeutic ratio, maximizing tumor control while limiting toxicity. PRT referral should be considered for any patient with symptomatic or asymptomatic sites of disease where local control is desired.

Association between definitive chemoradiotherapy wait-time and survival in locally-advanced cervical cancer: Implications during the coronavirus pandemic

OBJECTIVE

The current coronavirus pandemic caused a significant decrease in cancer-related encounters resulting in a delay in treatment of cancer patients. The objective of this study was to examine the survival effect of delay in starting concurrent chemo-radiotherapy (CCRT) in women with locally-advanced cervical cancer.

METHODS

This is a retrospective observational study querying the National Cancer Database from 2004 to 2016. Women with stage IB2-IVA squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the uterine cervix who received definitive CCRT with known wait-time for CCRT initiation after cancer diagnosis were eligible (N=13,617). Cox proportional hazard regression model with restricted cubic spline transformation was fitted to assess the association between CCRT wait-time and all-cause mortality in multivariable analysis.

RESULTS

The median wait-time to start CCRT was 6 (IQR 4-8) weeks. In a multivariable analysis, older age, non-Hispanic black and Hispanic ethnicity, recent year of diagnosis, Medicaid and uninsured status, medical comorbidities, and absence of nodal metastasis were associated with longer CCRT wait-time (P<.05). Women with aggressive tumor factors (poorer differentiation, large tumor size, nodal metastasis, and higher cancer stage) were more likely to have a short CCRT wait-time (P<.05). After controlling for the measured covariates, CCRT wait-time of 6.1-9.8 weeks was not associated with increased risk of all-cause mortality compared to a wait-time of 6 weeks. Similar association was observed when the cohort was stratified by histology, cancer stage, tumor size, or brachytherapy use.

CONCLUSION

An implication of this study for the current coronavirus pandemic is that in the absence of aggressive tumor factors, a short period of wait-time to start definitive CCRT may not be associated with increased risk of mortality in women with locally-advanced cervical cancer.

How COVID-19 Pandemics Changed the Treatment Protocols for Patients with Gynecological Tumors

It was found that oncological patients are4 to 8 times more likely of developing severe forms of COVID-19 infection than other patients, so mortality is higher in patients with gyneco-logical cancer. Due to this pandemic, reported delays in diagnosis and treatment of genital cancer and changes in disease management, may influence the natural history of neoplasm. This fact adds more stress and fear for patients with neoplasms. Adequate protective measures are essen-tial for SARS CoV2 infection avoidance and lead to changes in healthcare professionals clinical practice. Prioritization is important, but direct personal interactions should be limited. However, gynecological tumors surgery, chemotherapy, and radiotherapy should continue as high priority practices, without essential modification. The conclusion is that COVID-19 pandemic has affect-ed many guides for management of diseases, especially oncological. Adaptations in clinical prac-tice may avoid viral infection and reduce mortality and severe complications.

The Impact of COVID-19 on Brachytherapy During the Pandemic: A Rutgers-Robert Wood Johnson Barnabas Health Multisite Experience

PURPOSE

This study aimed to evaluate whether the coronavirus disease of 2019 (COVID-19) pandemic resulted in treatment delays in patients scheduled for or undergoing brachytherapy.

METHODS AND MATERIALS

A retrospective cohort study was conducted across 4 affiliated sites after local institutional review board approval. The eligibility criteria were defined as all patients with cancer whose treatment plan included brachytherapy during the COVID-19 pandemic from February 24, 2020 to June 30, 2020. Treatment delays, cancellations, alterations of fractionation regimens, and treatment paradigm changes were evaluated.

RESULTS

A total of 47 patients were eligible for the analysis. Median patient age at the time of treatment was 62 years (interquartile range, 56-70 years). Endometrial, cervical, and prostate cancers were the most common sites included in this analysis. Three patients (6.4%) with cervical cancer were diagnosed with COVID-19 during the course of their treatment. Interruptions of external beam radiation therapy (EBRT), cancellations of EBRT, cancellations of brachytherapy, and treatment delays due to COVID occurred in 5 (10.6%), 3 (6.4%), 8 (17%), and 9 (19%) patients, respectively. The mean and median number of days delayed for patients who experienced treatment interruptions were 16.3 days (standard deviation: 13.9 days) and 14 days (interquartile range, 5.75-23.75 days), respectively. For patients with cervical cancer, the mean and median overall treatment times defined as the time from the start of EBRT to the end of brachytherapy were 56 and 49 days, respectively.

CONCLUSIONS

Despite the challenges the health care system faced during the pandemic, most patients with cancer were safely treated with minor treatment delays and interruptions. Long-term follow up is needed to assess the impact of COVID-19 and treatment interruptions on oncologic outcomes.

Cancer or COVID-19? A Review of Guidelines for Safe Cancer Care in the Wake of the Pandemic

In the wake of the COVID-19 pandemic, due to reasons beyond control, health care workers have struggled to deliver treatment for the patients with cancer. The concern for otherwise healthy patients with curable cancers that require timely intervention or therapy is the risk of contracting COVID-19 may outweigh the benefits of cancer treatment. Lack of international guidelines leaves health care providers with a case-to-case approach for delivering optimal cancer care in the wake of the pandemic. Transition to telemedicine has somewhat bridged the gap for in-office visits, but there is a continuing challenge of delays in cancer screening or significant decline of new diagnoses of cancers due to the pandemic. We aim to propose a balance in risk from treatment delay versus risks from COVID-19 with emphasis on treatment modality (surgery, radiation, and systemic therapy) as well as supportive care for cancer patients, and therefore have reviewed the publications and recommendations from international societies and study groups available as of October 2020.

COVID-19, Brachytherapy, and Gynecologic Cancers: a Moroccan Experience

The treatment of gynecological cancers is the main activity of brachytherapy units. However, during COVID-19 pandemic, precautions should be done in order to reduce the spread of the virus while maintaining all chances to recovery for all patients (Radiother Oncol 148, 227-228, 2020). Despite the extent of the pandemic in our country, limited data are available to establish recommendations with a sufficient level of evidence (Radiother Oncol 148, 227-228, 2020). More recently, the American Brachytherapy Society published some clarifications in this regard and international expert consensus recommendations of radiation therapy for gynecologic malignancies during the COVID-19 pandemic were published (https://www.americanbrachytherapy.org/about-abs/abs-news/abs-statement-on-coronavirus/, Gynecol Oncol 15, 2020). In this commentary, we sought to share the procedures adopted for the management of gynecological cancer patients during COVID-19 pandemic in our brachytherapy unit.
