Head and neck radiotherapy amid the COVID-19 pandemic: practice recommendations of the Italian Association of Radiotherapy and Clinical Oncology (AIRO)

Nursing Care for Metastatic Bone Cancer: Trends for the Future

To effectively treat patients and minimize viral exposure, oncology nurses and radiology departments during COVID-19 had to re-examine the ability to offer palliative radiation treatments to people with metastatic bone cancer. Decreasing potential exposure to the virus resulted in extra measures to keep patients and personnel safe. Limiting radiotherapy treatments, social distancing, and limiting caregivers were a few of the ways that oncology patients were impacted by the pandemic. Hypofractionated radiation therapy (HFRT), or the delivery of fewer higher-dose treatments, was a method of providing care but also limiting exposure to infection for immunocompromised patients as well as healthcare staff. As oncology radiation centers measure the impact of patient care during the pandemic, a trend toward HFRT may occur in treating the painful symptoms of bone cancer. In anticipation that HFRT may be increasingly used in patient treatment plans, oncology nurses should consider patient perspectives and outcomes from the pandemic to further determine how to manage future trends in giving personalized care, and supportive care.

Good clinical practice and the use of hypofractionation radiation schedules as weapons to reduce the risk of COVID-19 infections in radiation oncology unit: A mono-institutional experience

BACKGROUND

After coronavirus disease outbreak emerged in 2019, radiotherapy departments had to adapt quickly their health system and establish new organizations and priorities. The purpose of this work is to report our experience in dealing with COVID-19 emergency, how we have reorganized our clinical activity, changed our priorities, and stressed the use of hypofractionation in the treatment of oncological diseases.

MATERIALS AND METHODS

The patients' circuit of first medical examinations and follow-up was reorganized; a more extensive use of hypofractionated schedules was applied; a daily triage of the patients and staff, use of personal protective equipment, hand washing, environment sanitization, social distancing and limitations for the patients' caregivers in the department, unless absolutely essential, were performed; patients with suspected or confirmed COVID-19 were treated at the end of the day. In addition, the total number of radiotherapy treatment courses, patients and sessions, in the period from February 15 to April 30, 2020, comparing the same time period in 2018 were retrospectively investigated. In particular, changes in hypofractionated schedules adopted for the treatment of breast and prostate cancer and palliative bone metastasis were analyzed.

RESULTS

Between February 15, and April 30, 2020, an increased number of treatments was carried out: Patients treated were overall 299 compared to 284 of the same period of 2018. Stressing the use of hypofractionation, 2036 RT sessions were performed, with a mean number of fractions per course of 6.8, compared to 3566 and 12.6, respectively, in 2018. For breast cancer, the schedule in 18 fractions has been abandoned and treatment course of 13 fractions has been introduced; a 27% reduction in the use of 40.5 Gy in 15 fractions, (67 treatments in 2018-49 in 2020) was reported. An increase of 13% of stereotactic body radiation therapy for prostate cancer was showed. The use of the 20 Gy in 4 or 5 sessions for the treatment of symptomatic bone metastasis decreased of 17.5% in favor of 8 Gy-single fraction. Three patients results COVID-19 positive swab: 1 during, 2 after treatment. Only one staff member developed an asymptomatic infection.

CONCLUSIONS

The careful application of triage, anti-contagion and protective measures, a more extensive use of hypofractionation allowed us to maintain an effective and continuous RT service with no delayed/deferred treatment as evidenced by the very low number of patients developing COVID-19 infection during or in the short period after radiotherapy. Our experience has shown how the reorganization of the ward priority, the identification of risk factors with the relative containment measures can guarantee the care of oncological patients, who are potentially at greater risk of contracting the infection.

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 COVID-19 Pandemic on Patterns of Care and Outcome of Head and Neck Cancer: Real-World Experience From a Tertiary Care Cancer Center in India

The COVID-19 pandemic has caused unprecedented health, social, and economic unrest globally, particularly affecting resource-limited low-middle–income countries. The resultant curfew had made the access to and delivery of cancer care services an arduous task. We have reported the patterns of care and 1-year outcome of head and neck squamous cell carcinoma (HNSCC) treatment before and during COVID-19 lockdown at our institution.

COVID-19 manifestation in the oral cavity - a narrative literature review

COVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a recently discovered coronavirus, which in 2020 led to a global pandemic. Clinical manifestations of COVID-19 are very diverse and symptoms range from mild to severe. Correlated symptoms might also manifest in the oral cavity, which is a potential pathway for viral infection, and therefore might be a potential pathway for SARS-CoV-2. In recent research among patients with SARS-CoV-2 infection, taste and olfactory disorders, dry mouth, drones and inflammation of mouth, bitter taste in mouth, difficulty in swallowing and burning sensations have been reported. There have been cases of oral mucosal lesions in patients diagnosed with COVID-19 disease. Some correlations between periodontitis and severity of COVID-19 disease have also been observed. Oral mucosa, due to occurrence of ACE2 receptors, is highly susceptible to SARS-CoV-2 infection. The occurrence of changes on oral mucosa should increase the alertness of dental practitioners. However, knowledge in this area is still limited and in the field of oral manifestations of COVID-19 more research and patient observations are required.

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.

Universal testing for COVID-19 in patients undergoing cancer treatment during the second outbreak in Brescia

BACKGROUND

The impact of coronavirus disease 2019 (COVID-19) has been overwhelming on patients with cancer, who may be at higher risk of developing severe disease. During the second COVID-19 outbreak in Italy, we planned universal microbiologic screening for patients scheduled for antineoplastic treatment.

METHODS

All patients with planned active treatment at Brescia University Radiation Oncology Department were screened for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA with repeated nasopharyngeal swabs (NPS) from October 31, 2020. Treatment continuation, suspension, or delay was modulated for patients testing positive according to clinical presentation.

RESULTS

From October 31, 2020, to February 6, 2021, 636 patients were enrolled and 1243 NPS were performed, of which 28 (2.25%) were positive. The infection rate was 2.52%; 81.3% of the patients with a positive NPS were asymptomatic, 2 had mild disease, and 1 severe disease that led to death. All patients already on treatment with mild or asymptomatic COVID-19 carried on the therapy with no or minimal delay. Median delay for patients with infection detected before treatment start was 16.5 days.

CONCLUSIONS

Detected incidence of COVID-19 was lower during the second outbreak in our patients (2.52% vs 3.23%), despite the extensive testing schedule, and substantiates the high rate of asymptomatic infections and the low mortality among patients with COVID-19 (6.3% vs 38.5% during the first outbreak). Universal SARS-CoV-2 screening for all patients with planned treatment might allow early identification of patients with COVID-19, resulting in timely management that could improve clinical outcomes and prevent spread of the infection.

Uncertainty in the positioning of patients receiving treatment for brain metastases and wearing surgical mask underneath thermoplastic mask during COVID-19 crisis

Thermoplastic masks, used along with surgical masks, enable immobilization methods to reduce the risk of infection in patients undergoing intracranial stereotactic radiosurgery and stereotactic radiotherapy (SRS/SRT) during the COVID‐19 crisis. The purpose of this study was to investigate the feasibility of thermoplastic mask immobilization with a surgical mask using an ExacTrac system. Twelve patients each with brain metastases were immobilized using a thermoplastic mask and a surgical mask and only a thermoplastic mask. Two x‐ray images were acquired to correct (XC) and verify (XV) the patient’s position at a couch angle of 0°. Subsequently, the XC and XV images were acquired at each planned couch angle for non‐coplanar beams. When the position errors were detected after couch rotation for non‐coplanar beams, the errors were corrected at each planned couch angle until a clinically acceptable tolerance was attained. The position errors in the translational and rotational directions (vertical, lateral, longitudinal, pitch, roll, and yaw) were retrospectively investigated using data from the ExacTrac system database. A standard deviation of XC translational and rotational position errors with and without a surgical mask in the lateral (1.52 vs 2.07 mm), longitudinal (1.59 vs 1.87 mm), vertical (1.00 vs 1.73 mm), pitch (0.99 vs 0.79°), roll (1.24 vs 0.68°), and yaw (1.58 vs 0.90°) directions were observed at a couch angle of 0°. Most of patient positioning errors were less than 1.0 mm or 1.0° after the couch was rotated to the planned angle for non‐coplanar beams. The overall absolute values of the translational and rotational XV position errors with and without the surgical mask were less than 0.5 mm and 0.5°, respectively. This study showed that a thermoplastic mask with a surgical mask is a feasible immobilization technique for brain SRS/SRT patients using the ExacTrac system.

Delphi Project on the trends in Implant Dentistry in the COVID-19 era: Perspectives from Latin America

AIM

To establish trends in Implant Dentistry in Latin America in the COVID-19 pandemic.

MATERIAL AND METHODS

A steering committee and an advisory group of experts in Implant Dentistry were selected among eighteen countries. An open-ended questionnaire by Delphi methodology was validated including 64 questions, divided in 7 topics, concerning the various trends in dental implantology. The survey was conducted in two rounds, which provided the participants in the second round with the results of the first. The questionnaires were completed on August 2020, and the online meeting conference was held on September 2020. The final prediction was developed through consensus by a selected group of experts.

RESULTS

A total of 197 experts from Latin America answered the first and second questionnaire. In the first round, the established threshold for consensus (65%) was achieved in 30 questions (46.87%). In the second round, performed on average 45 days later, this level was achieved in 47 questions (73.43%). Consensus was completely reached on the item "Diagnostic" (100%), the field with the lowest consensus was "Demand for treatment with dental implants" (37.5%).

CONCLUSIONS

The present study in Latin America has provided relevant and useful information on the predictions in the education and practice of Implant Dentistry in the COVID-19 era. The consensus points toward a great confidence of clinicians in the biosecurity protocols used to minimize the risk of SARS-CoV-2 transmission. It is foreseen as an important change in education, with introduction of virtual reality and other simulation technologies in implant training.

Recurrent Nasopharyngeal Cancer: Critical Review of Local Treatment Options Including Recommendations during the COVID-19 Pandemic

Simple Summary

Options for the curative treatment of locally recurrent nasopharyngeal carcinoma include surgery or re-irradiation. Both approaches have been scientifically explored, yet there is no consensus on the indication or definitive preference of the above two salvage treatments. The aim of this review is to summarize the current evidence on the local treatment of recurrent nasopharyngeal carcinoma. The feasibility, safety, and efficacy of salvage surgery and radical re-irradiation are discussed. Recommendations on treatment modifications during the coronavirus disease 2019 pandemic are included as well.

Abstract

Recurrent nasopharyngeal carcinoma represents an extremely challenging therapeutic situation. Given the vulnerability of the already pretreated neurological structures surrounding the nasopharynx, any potential salvage retreatment option bears a significant risk of severe complications that result in high treatment-related morbidity, quality of life deterioration, and even mortality. Yet, with careful patient selection, long-term survival may be achieved after local retreatment in a subgroup of patients with local or regional relapse of nasopharyngeal cancer. Early detection of the recurrence represents the key to therapeutic success, and in the case of early stage disease, several curative treatment options can be offered to the patient, albeit with minimal support in prospective clinical data. In this article, an up-to-date review of published evidence on modern surgical and radiation therapy treatment options is summarized, including currently recommended treatment modifications of both therapeutic approaches during the coronavirus disease 2019 pandemic.
