With the emergence of second wave of COVID-19 infection globally, particularly in India in March-April 2021, protection by massive vaccination drive has become the need of the hour. Vaccines have been proved to reduce the risk of developing severe illness and are emerging as vital tools in the battle against COVID-19. ⋯ Nevertheless, a considerable degree of doubt, hesitancy and misconceptions are noted regarding the administration of vaccines particularly during active immuno-suppressant treatment. This review article highlights the added vulnerability of cancer patients to the COVID-19 infection and has explored the immunological challenges associated with malignancy, anticancer treatment and COVID-19 vaccination.

Prostate-specific membrane antigen (PSMA; also termed glutamate carboxypeptidase II (GCP II)) is abundantly expressed in prostate cancer. It has been shown recently that PSMA is expressed in neovasculature of differentiated thyroid cancer. In this study, we show that 18F-DCFPyl might detect neovasculature in advanced, metastatic differentiated thyroid cancer (DTC). ⋯ In the second imaged patient, 18F-DCFPyl showed intense uptake in the L3 vertebra (not seen on the post treatment 131I scan or the 18F-FDG PET/CT). MRI of the lumbar spine confirmed the presence of sclerotic-lytic lesion at the location, consistent with metastatic disease. Our exploratory study is proof of principle, that the prostate cancer imaging agent 18F-DCFPyl may prove useful for the localization of metastases, in patients with metastatic RAI-refractory DTC by detecting neoangiogenesis within the tumor.

Questions asked through two examples of dilemmas of publication ethics in the process of COVID-19.
The COVID-19 pandemic is a kind of global disaster caused by the new coronavirus-19, the SARS-CoV-2 virus. Since the first eruption of this pandemic, which adversely affected the world in many ways, a large number of publications have been presented to the world of science. In this article, possible publication ethical dilemmas related to scientific articles increasing in number during the COVID-19 pandemic were tried to be reminded through two examples of articles.

Management of patients with head and neck cancers (HNCs) is challenging for the Radiation Oncologist, especially in the COVID-19 era. The Italian Society of Radiotherapy and Clinical Oncology (AIRO) identified the need of practice recommendations on logistic issues, treatment delivery and healthcare personnel's protection in a time of limited resources. A panel of 15 national experts on HNCs completed a modified Delphi process. ⋯ There was agreement or strong agreement across the majority (93%) of proposed items including treatment strategies, use of personal protection devices, set-up modifications and follow-up re-scheduling. Guaranteeing treatment delivery for HNC patients is well-recognized in Radiation Oncology. Our recommendations provide a flexible tool for management both in the pandemic and post-pandemic phase of the COVID-19 outbreak.

The COVID-19 pandemic has deeply impacted the activity of interventional oncology in cancer centers. Since the first COVID case was diagnosed in Italy on February 21st, our Hospital, located in Milan downtown, has been at the frontline to manage this emergency and to try to ensure essential services. In the present article, we discuss the changes that need to be done for the organization, safety, and patient management in interventional oncology.
