Predictors of poor precautionary practices towards COVID-19 among cancer patients.

Objective: Our study goal was to evaluate the behavioral response and practices of cancer patients to the coronavirus disease 2019 (COVID-19) pandemic in the Middle East and north Africa. Methods: A cross-sectional study was conducted using a validated anonymous 45-question survey administered via SurveyMonkey® to cancer patients in 13 centers in Algeria, Egypt, Jordan, Kuwait, Morocco and Saudi Arabia. Results: During the study period (from 21 April to 30 May 2020), 3642 patients participated in the study. The majority of patients (84.81%) were worried about contracting the infection. The reported strict adherence to precautions included avoiding the following actions: hand-shaking (77.40%), hugging and kissing (82.89%), social gathering (90.09%), meeting friends (84.68%) and visiting markets (75.65%). In a multivariate analysis, patients with poor precautionary practices were about twice as likely to cancel their medical appointment or a treatment session. Conclusion: Improving cancer patients' knowledge of and adherence to precautionary measures is needed not just to reduce the risk of acquiring infection but also to minimize the interruption of their medical care.

Lay abstract COVID-19 poses a higher risk for patients with cancer than other patients; therefore, it is prudent that they adhere to precautionary measures to protect themselves from the infection. We conducted a study to evaluate the behaviors and practices of these patients in response to the COVID-19 pandemic in the Middle, East and North Africa. We developed a survey of 45 questions that was distributed in 13 centers in Algeria, Egypt, Jordan, Kuwait, Morocco and Saudi Arabia between 21 April and 30 May 2020. About 85% of the 3642 patients who participated in the study were worried about contracting the infection. A substantial percentage of them (10­30%) were not adhering to various precautions and social distancing rules. On the other hand, 16% of them canceled medical appointments and 12% canceled treatment sessions. Our study showed the need for better adherence of patients with cancer to the infection precautions and most importantly, the need to have a better compliance with their treatment plans, such as keeping their scheduled appointments, to avoid harms from treatment delays.

Clinico-pathological relationship between androgen receptor and tumour infiltrating lymphocytes in triple negative breast cancer.

BACKGROUND: Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer (BC) with ill-defined therapeutic targets. Androgen receptor (AR) and tumour-infiltrating lymphocytes (TILs) had a prognostic and predictive value in TNBC. The relationship between AR, TILs and clinical behaviour is still not fully understood. METHODS: Thirty-six TNBC patients were evaluated for AR (positive if ≥1% expression), CD3, CD4, CD8 and CD20 by immunohistochemistry. Stromal TILs were quantified following TILs Working Group recommendations. Lymphocyte-predominant breast cancer (LPBC) was defined as stromal TILs ≥ 50%, whereas lymphocyte-deficient breast cancer (LDBC) was defined as <50%. RESULTS: The mean age was 52.5 years and 27.8% were ≥60 years. Seven patients (21.2%) were AR+. All AR+ cases were postmenopausal (≥50 years old). LPBC was 32.2% of the whole cohort. Median TILs were 37.5% and 10% (p = 0.1) and median CD20 was 20% and 7.5% (p = 0.008) in AR- and AR+, respectively. Mean CD3 was 80.7% and 93.3% (p = 0.007) and CD8 was 75% and 80.8% (p= 0.41) in AR- and AR+, respectively. All patients who were ≥60 years old expressed CD20. LDBC was found to be significantly higher in N+ versus N- patients (p = 0.03) with median TILs of 20% versus 50% in N+ versus N-, respectively (p = 0.03). LDBC was associated with higher risk of lymph node (LN) involvement (odds ratio = 6; 95% CI = 1.05-34.21; p = 0.04). CONCLUSIONS: AR expression was evident in older age (≥50 years). Median CD20 was higher in AR- TNBC, while mean CD3 was higher in AR+ tumours. LDBC was associated with higher risk of LN involvement. Larger studies are needed to focus on the clinical impact of the relation between AR and TILs in TNBC.
