Background: The increased susceptibility of cancer patients to coronavirus disease-2019 (COVID-19) infections and complications calls for special precautions while treating cancer patients during COVID-19 pandemics. Thus, oncology departments have had to implement a wide array of prevention measures.

Objectives: To address issues associated with cancer care during the COVID-19 pandemic and to assess the implementation of measures aimed at containment of COVID-19 diffusion while allowing continuation of quality cancer care.

Methods: A national survey among oncology departments in Israel was conducted between 12 April 2020 and 14 April 2020. Eighteen heads of hospital-based oncology departments completed a self-report questionnaire regarding their institute's preparedness for treatment of cancer patients during the COVID-19 pandemic.

Results: In this national survey, prevention measures against COVID-19 spread were taken prior to patients' arrival and at arrival or while staying in the departments. Most participants (78–89%) reported using a quick triage of patients and caregivers prior to their entrance to the oncology units, limiting the entrance of caregivers, and reducing unnecessary visits to the clinic. Switching to oral therapies rather than intravenous ones when possible was considered by 82% and shortage in personal protective equipment was reported by five (28%) heads of oncology departments. Some differences between large and small/medium sized medical centers were observed regarding issues related to COVID-19 containment measures and changes in treatment.

Conclusions: Oncology departments in Israel were able to prepare and adapt their services to guidelines and requirements related to the COVID-19 pandemic with little harm to their treatment capacity

Background: Radiotherapy to the prostate bed is used to eradicate residual microscopic disease following radical prostatectomy for prostate cancer. Recommendations are based on historical series. 

Objectives: To determine outcomes and toxicity of contemporary salvage radiation therapy (SRT) to the prostate bed. 

Methods: We reviewed a prospective ethics committee-approved database of 229 patients referred for SRT. Median pre-radiation prostate-specific antigen (PSA) was 0.5 ng/ml and median follow-up was 50.4 months (range 13.7–128). Treatment was planned and delivered using modern three-dimensional radiation techniques. Mean bioequivalent dose was 71 Gy (range 64–83 Gy). Progression was defined as two consecutive increases in PSA level > 0.2 ng/ml, metastases on follow-up imaging, commencement of anti-androgen treatment for any reason, or death from prostate cancer. Kaplan-Meier survival estimates and multivariate analysis was performed using STATA. 

Results: Five year progression-free survival was 68% (95%CI 59.8–74.8%), and stratified by PSA was 87%, 70% and 47% for PSA < 0.3, 0.3–0.7, and > 0.7 ng/ml (P < 0.001). Metastasis-free survival was 92.5%, prostate cancer-specific survival 96.4%, and overall survival 94.9%. Low pre-radiation PSA value was the most important predictor of progression-free survival (HR 2.76, P < 0.001). Daily image guidance was associated with reduced risk of gastrointestinal and genitourinary toxicity (P < 0.005). 

Conclusions: Contemporary SRT is associated with favorable outcomes. Early initiation of SRT at PSA < 0.3 ng/ml improves progression-free survival. Daily image guidance with online correction is associated with a decreased incidence of late toxicity.

Background: The VEGFR/PDGFR inhibitor sunitinib was approved in Israel in 2008 for the treatment of metastatic renal cell carcinoma (mRCC), based on an international trial. However, the efficacy of sunitinib treatment in Israeli mRCC patients has not been previously reported.

Objectives: To report the outcome and associated factors of sunitinib treatment in a large cohort of Israeli mRCC patients.

Methods: We conducted a retrospective study of an unselected cohort of mRCC patients who were treated with sunitinib during the period 2006–2013 in six Israeli hospitals. Univariate and multivariate analyses were performed to determine the association between treatment outcome and clinicopathologic factors.

Results: We identified 145 patients; the median age was 65 years, 63% were male, 80% had a nephrectomy, and 28% had prior systemic treatment. Seventy-nine percent (n=115) had clinical benefit (complete response 5%, n=7; partial response 33%, n= 48; stable disease 41%, n=60); 21% (n=30) were refractory to treatment. Median progression-free survival (PFS) was 12 months and median overall survival 21 months. Factors associated with clinical benefit were sunitinib-induced hypertension: [odds ratio (OR) 3.6, P = 0.042] and sunitinib dose reduction or treatment interruption (OR 2.4, P = 0.049). Factors associated with PFS were female gender [hazard ratio (HR) 2, P = 0.004], pre-sunitinib treatment neutrophil to lymphocyte ratio ≤ 3 (HR 2.19, P = 0.002), and active smoking (HR 0.19, P < 0.0001). Factors associated with overall survival were active smoking (HR 0.25, P < 0.0001) and sunitinib-induced hypertension (HR 0.48, P = 0.005). To minimize toxicity, the dose was reduced or the treatment interrupted in 39% (n=57). 

Conclusions: The efficacy of sunitinib treatment for mRCC among Israeli patients is similar to that of international data.
