Radiotherapy during COVID-19 pandemic. How to create a No fly zone: a Northern Italy experience.

BACKGROUND: SARS-CoV-2 pandemic represents a troubling health emergency but also a main challenge for the clinical governance of the system. Discontinuation of radiation treatments is not desirable and potentially life-threatening. On the other hand, accesses to hospital expose cancer patients to an increased risk of COVID-19 infection. We report our extended protocol, draft to manage clinical activities in our radiotherapy department, by minimizing contagion risks. METHODS: We used telephonic screening to assess the need for patient admission. A telephonic triage was performed to identify the presence of COVID-19 infection risk factors or symptoms. New treatments were stratified according to priority codes. A reserved entrance to radiotherapy department was assured for patients and staff. Surgical disposable mask was required for patients and caregivers. The activities were distributed during the whole workday, avoiding overlap to reduce aggregation. RESULTS: From 1st February 2020 to 31 March 2020, we reported an increase in the number of first medical examinations and treatments, compared to the same period of the previous year. Outpatients first medical examinations have been spread over the 12 working hours. No COVID-19 cases were detected. CONCLUSION: During COVID-19 pandemic, we introduced procedures that allowed us to ensure the continuity in oncological cares, with limited risks of infection for patients and staff.

Policies for reirradiation of recurrent high-grade gliomas: a survey among Italian radiation oncologists.

PURPOSE: To assess the contribution of Italian radiation oncologists in the current management of recurrent high-grade gliomas (HGG), focusing on a reirradiation (reRT) approach. METHODS: In 2015, the Reirradiation and the Central Nervous System Study Groups on behalf of the Italian Association of Radiation Oncology (AIRO) proposed a survey. All Italian radiation oncologists were individually invited to complete an online questionnaire regarding their clinical management of recurrent HGG, focusing on a reRT approach. RESULTS: A total of 37 of 210 questionnaires were returned (18% of all centers): 16 (43%) from nonacademic hospitals, 14 (38%) from academic hospitals, 5 (13%) from private institutions, and 2 (6%) from hadron therapy centers. The majority of responding centers (59%) treated ≤5 cases per year. Performance status at the time of recurrence, along with a target diameter <5 cm and an interval from primary radiation ≥6 months, were the prevalent predictive factors considered for reRT. Sixty percent of reirradiated patients had already received a salvage therapy, either chemotherapy (40%) or reoperation (20%). The most common approach for reRT was fractionated stereotactic radiotherapy to a mean (photon) dose of 41.6 Gy. CONCLUSIONS: Although there were wide variations in the clinical practice of reRT across the 37 centers, the core activities were reasonably consistent. These findings provide a basis for encouraging a national collaborative study to develop, implement, and monitor the use of reRT in this challenging clinical setting.

Epstein-Barr Virus-Positive Mucocutaneous Ulcer Mimicking Rectal Carcinoma at 18F-FDG PET/CT.

We report focally intense F-FDG PET/CT rectal activity (SUVmax = 25) with a horseshoe distribution in an 81-year-old man with B-cell chronic lymphocytic leukemia and suspected Richter transformation. While imaging findings were typical for rectal adenocarcinoma, histology revealed Epstein-Barr virus-positive mucocutaneous ulcer.

Oral toxicity management in head and neck cancer patients treated with chemotherapy and radiation: Dental pathologies and osteoradionecrosis (Part 1) literature review and consensus statement.

Radiotherapy alone or in combination with chemotherapy and/or surgery is the typical treatment for head and neck cancer patients. Acute side effects (such as oral mucositis, dermatitis, salivary changes, taste alterations, etc.), and late toxicities in particular (such as osteo-radionecrosis, hypo-salivation and xerostomia, trismus, radiation caries etc.), are often debilitating. These effects tend to be underestimated and insufficiently addressed in the medical community. A multidisciplinary group of head and neck cancer specialists met in Milan with the aim of reaching a consensus on clinical definitions and management of these toxicities. The Delphi Appropriateness method was used for developing the consensus, and external experts evaluated the conclusions. This paper contains 10 clusters of statements about the clinical definitions and management of head and neck cancer treatment sequels (dental pathologies and osteo-radionecroses) that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecroses (10 clusters of statements), whereas this second part deals with trismus and xerostomia.

Dysphagia in head and neck cancer patients treated with radiotherapy and systemic therapies: Literature review and consensus.

BACKGROUND: Head and neck cancer (HNC) and its therapy are associated with acute and late swallowing dysfunction. Consensus guidelines regarding evaluation and management are lacking. To address this gap, a multidisciplinary team of experts (oncologists, practitioners, deglutologists, etc.) met in Milan 17-18 February 2013 with the aim of reaching a consensus on the management of swallowing difficulties in HNC patients treated with radiotherapy with or without systemic therapies (such as chemotherapy and targeted agents). The consensus was focused particularly on those statements with limited evidence. The results of the literature review and the statements that obtained a consensus are reported and discussed in this paper. MATERIALS AND METHODS: The Delphi Appropriateness Method was used for this consensus. External expert reviewers then evaluated the conclusions carefully according to their area of expertise. RESULTS: This paper contains 6 clusters of statements about the management of swallowing problems in radio-treated HNC patients and a review of the recent literature on these topics. CONCLUSIONS: Dysphagia assessment and its management are difficult and require a multi-team cooperation (ENT specialists, radiation and medical oncologists, deglutologists, etc.).

Response criteria for malignant lymphoma.

In the last 35 years, many attempts have been made to define criteria for the assessment of treatment response in malignant lymphoma. These systems, with respect to both morphological and molecular imaging, aim to standardize scan results, in order to simplify the interpretation of findings, facilitate multicentric research trials, and compare published data. Unfortunately, there is no consensus among the main international hematological associations on which criteria are the most appropriate. This detailed and comprehensive description of all classifications intends to focus attention on this topic.

Predictive factors for oropharyngeal mycosis during radiochemotherapy for head and neck carcinoma and consequences on treatment duration. Results of mycosis in radiotherapy (MIR): a prospective longitudinal study.

BACKGROUND AND PURPOSE: Oropharyngeal mycosis (OPM) is a complication of radiotherapy (RT) treatments for head and neck (H&N) cancer, worsening mucositis and dysphagia, causing treatment interruptions and increasing overall treatment time. Prophylaxis with antifungals is expensive. Better patient selection through the analysis of prognostic factors should improve treatment efficacy and reduce costs. MATERIALS AND METHODS: A multicentre, prospective, controlled longitudinal study, with ethics committee approval, examined H&N cancer patients who were candidates for curative treatments with radio-chemotherapy. Patients were divided in groups according to OPM appearance: before the starting of RT (cases), during RT (new cases) and never (no cases). RESULTS: Of 410 evaluable patients, 20 were existing cases, 201 new cases and 189 did not report OPM. In our study OPM appears in 42.4% of people >70years and in 58.2% of younger individuals (p=0.0042), and in 68.6% of women versus 50.8% of men (p=0.0069). Mucositis and dysphagia were higher and salivation reduced among people with OPM (p<0.0000). Patients with OPM had longer hospitalization (p=0.0002) and longer (>12days) treatment interruptions (p=0.0288). CONCLUSIONS: Patients with OPM had higher toxicity and a greater number of long treatment interruptions. Analyses of prognostic factors can help clinicians understand OPM distribution and select patients with the highest probability of OPM for antifungal prophylaxis.
