Perceptions of the COVID-19 vaccine among patients with cancer: a single-institution survey.

Aims: This paper reports the results of a survey assessing the acceptance of the COVID-19 vaccine among patients with cancer. Patients and methods: In total, 111 adult patients with cancer from a single institution were asked to complete a questionnaire designed to assess their knowledge about the vaccine, their readiness to be vaccinated and the determinants of their decision. Results: 61.3% of the patients considered themselves more vulnerable to COVID-19 than the general population. Television, radio and newspapers were the major sources of information about the vaccine. A total of 55% of the patients were ready to be vaccinated and 14.4% refused the vaccine. The main reason for refusal was incompatibility with patients' disease or treatment. Conclusion: Most of the patients in this institutional sample accepted the COVID-19 vaccine. Better communication of information with patients is needed to decrease vaccine hesitancy.

Lay abstract Major cancer societies consider vaccinating patients with cancer against COVID-19 a priority. The investigators conducted a survey assessing perceptions of the vaccine among patients with cancer. A total of 111 patients were asked to complete a questionnaire evaluating their knowledge about the vaccine, their readiness to be vaccinated and the determinants of their decision. Most (61.3%) patients considered themselves more susceptible to COVID-19 than the general population. Television, radio and newspapers were the major sources of information about the vaccine. The majority of patients (55%) were ready to be vaccinated and 14.4% refused the vaccine. The main reason for refusal was incompatibility with patients' disease or treatment. Better communication with patients is needed to decrease vaccine hesitancy.

Molecular pathogenesis of hereditary lung cancer: a literature review.

Among all cancer types, pulmonary cancer has the highest mortality rate. Tobacco consumption remains the major risk factor for the development of lung cancer. However, many studies revealed a correlation between inherited genetic variants and predisposition to lung cancer, especially in nonsmokers. To date, genetic testing for the detection of germline mutations is not yet recommended in patients with lung cancer and testing is focused on somatic alterations given their implication in the treatment choice. Understanding the impact of genetic predisposition on the occurrence of lung cancer is essential to enable the introduction of accurate guidelines and recommendations that might reduce mortality. In this review paper, we describe familial lung cancer, and expose germline mutations that are linked to this type of cancer. We also report pathogenic genetic variants linked to syndromes associated with lung cancer.

Immune checkpoint inhibitors for advanced or metastatic basal cell carcinoma: how much evidence do we need?

Basal cell carcinoma (BCC) is one of the most frequent and most curable tumors at its early stages. BCC rarely metastasizes and its treatment in this setting is still challenging. Hedgehog inhibitors showed an activity in advanced or metastatic disease. However, there is an unmet need for new agents. Immune checkpoint inhibitors have been assessed in melanoma and other cutaneous tumors, and very recently an anti-PD1 was approved for advanced BCC. In this paper, available data are reviewed on experimental and preclinical studies evaluating immunotherapy in BCC, as well as on the clinical evidence supporting the efficacy and safety of immune checkpoint inhibitors for advanced or metastatic BCC based on case reports, case series and clinical trials.

First advanced course on biomarkers in molecular and immuno-oncology in the Middle East.

The first 'advanced course on biomarkers in molecular and immuno-oncology' in the Middle East took place in Beirut, Lebanon, as a hybrid meeting on 11 December 2020. The aim of this seminar was to discuss biomarker development, implications and detection modalities and to highlight advances in molecular technologies as well as the clinical applicability of biomarkers in oncology. The seminar consisted of five sessions, each discussing a special topic in the biomarker field. It also included a competition in the form of a quiz following each session. This was followed by a plenary session presented by well-known national and international speakers, highlighting various aspects of biomarkers in immuno-oncology.

Cancer management during the COVID-19 pandemic: Choosing between the devil and the deep blue sea.

COVID-19 was declared a "Public Health Emergency of International Concern" in March 2020. Since then, drastic measures were implemented to reduce the virus spread. These measures prevented cancer patients from receiving prompt medical care. A delay in testing and treating cancer patients is thought to protect them from serious COVID-19 complications but exposes them at the same time to the risk of disease progression and cancer related mortality. Healthcare providers are therefore facing the dilemma of choosing between two unpleasant scenarios. To shed light upon the matter, we present in this review article, based on an extensive search of the literature, an overview of the delay in the management of cancer patients, possible contributors to this delay and its benefits and risks on cancer patients' health.

Exploring the knowledge gap of immune checkpoint inhibitors in chronic renal failure: A systematic review of the literature.

Targeting the immune system with immune checkpoint inhibitors (ICI) to treat cancer has been lately adopted with a significant improvement of patients' survival. In parallel, the incidence of malignancy in chronic kidney disease (CKD) patients is increasing, but solid evidence concerning the efficacy and safety of ICI in this population is lacking. Moreover, the use of these agents as immunity boosters in kidney graft recipients treated with immunosuppressors is still controversial. We present in this article a review of the pharmacological properties of these drugs and their behavior with kidney failure and dialysis, as well as evidence of their use in different populations of CKD. Most of the available data are limited to case reports and case series. These drugs appear to be safe without dose adjustment in CKD patients and patients on dialysis. A major concern with this therapy in transplanted patients remains the risk of graft rejection.

Poly-(ADP-ribose) polymerase inhibitors: paradigm shift in the first-line treatment of newly diagnosed advanced ovarian cancer.

Debulking surgery associated with chemotherapy represent the backbone of ovarian cancer therapy. Adding bevacizumab has improved survival. Recently, PARP inhibitors were added in the first line as maintenance treatment for the patients who achieve a complete or partial response. These drugs act by blocking the activity of the PARP enzyme responsible for base-excision repair, and have shown positive responses when used for tumors lacking homologous recombination. Olaparib, niraparib and veliparib were evaluated and showed an increase in the duration of progression-free survival: 22.1 months (hazard ratio [HR] = 0.59), 13.8 (HR = 0.62) and 23.5 (HR = 0.68) with olaparib, niraparib and veliparib, respectively. This review describes the benefit of PARP inhibitors as maintenance therapy and discusses the efficacy according to breast cancer gene and homologous recombination status.

Cancer patients and research during COVID-19 pandemic: A systematic review of current evidence.

The novel coronavirus, also known as SARS-Cov-2 or COVID-19 has become a worldwide threat and the major healthcare concern of the year 2020. Cancer research was directly affected by the emerging of this disease. According to some Chinese studies, cancer patients are more vulnerable to COVID-19 complications. This observation led many oncologists to change their daily practice in cancer care, without solid evidence and recommendations. Moreover, the COVID-19 manifestations as well as its diagnosis are particular in this special population. In this review paper we expose the challenges of cancer management in the era of SARS-CoV-2, the epidemiological, clinical, pathological and radiological characteristics of the disease in cancer patients and its outcomes on this population. Finally, we focus on strategies that are followed in cancer management with review of national and international guidelines.

The emerging use of immune checkpoint blockade in the adjuvant setting for solid tumors: a review.

The use of immune checkpoint inhibitors has been approved in the advanced and metastatic setting for many types of solid tumors. Nonetheless, their role in the adjuvant setting is limited to the treatment of surgically resected melanoma. Ipilimumab was the first immune checkpoint inhibitor approved for this indication, followed by nivolumab and pembrolizumab. Many ongoing trials are evaluating these molecules in the postoperative setting, alone or in combination with other therapies. Preliminary results are promising regarding the treatment of other cutaneous tumors, lung cancers, head and neck squamous cell carcinomas, bladder cancer and renal cell carcinomas. Some data assessing their use for the adjuvant treatment of esophageal, colorectal, ovarian cancer and other solid tumors are similarly emerging.

The Therapeutic use of human albumin in cancer patients' management.

Human albumin (HA) has been widely used in clinical practice due to its unique physiological characteristics and pharmacokinetics. However, with the absence of clear institutional recommendations, its uncontrolled prescription remains largely controversial. An extensive review on the albumin chemistry, pharmacology, physiology and pathology was performed, and data on commercially available HA, its cost, medical usage and the related available guidelines, particularly in oncology patients were gathered. Studies assessing the appropriate use and safety of HA in cancer patients are lacking. A retrospective survey of the appropriateness of HA infusions according to the SIMTI guidelines (2009) was performed in our department. Among 53 patients who received HA infusions, only 5.7% of the indications were appropriate for HA administration. Occasionally appropriate and inappropriate indications were considered in 10% and 84.3% of the prescriptions respectively with a relatively high cost. The adoption of strict guidelines may substantially reduce the inappropriate use and the subsequent healthcare costs.
