Transl Oncol 2021 Apr 14;14(7):101087. Epub 2021 Apr 14.

Department of Mechanical and Industrial Engineering, College of Engineering, Qatar University, 2713 Doha, Qatar; Biomedical Research Center (BRC), Qatar University, PO Box 2713 Doha, Qatar. Electronic address:

Metastasis is the major reason for most brain tumors with up to a 50% chance of occurrence in patients with other types of malignancies. Brain metastasis occurs if cancer cells succeed to cross the 'blood-brain barrier' (BBB). Moreover, changes in the structure and function of BBB can lead to the onset and progression of diseases including neurological disorders and brain-metastases. Read More

Local and Regional Recurrences of Clinically Localized Renal Cell Carcinoma after Nephrectomy: A 15 Year Institutional Experience with Prognostic Features and Oncologic Outcomes.

Urology 2021 Apr 14. Epub 2021 Apr 14.

Department of Urology, The James Buchanan Brady Urological Institute, Johns Hopkins University School of Medicine, Baltimore, MD. Electronic address:

Objective: To evaluate outcomes for patients with local recurrence (LR) of clinically localized renal cell carcinoma (RCC) without concurrent systemic metastasis from our institution, an event that occurs rarely (1-3%) after surgery. LR may be a harbinger of poor outcomes, and the best management of these patients is unclear.

Materials/methods: We retrospectively reviewed patients surgically treated for clinically localized RCC (cT1-2N0M0) with subsequent LR (in the partial or radical nephrectomy bed) and/or regional recurrence (RR; in the abdomen distant from the direct site of surgery) without concurrent metastasis from our institutional database (2004-2018).

Modeling of Tumor Control Probability in Stereotactic Body Radiation Therapy for Adrenal Tumors.

Int J Radiat Oncol Biol Phys 2021 May;110(1):217-226

Department of Radiation Oncology, Icahn School of Medicine at Mount Sinai, New York, New York.

Purpose: Stereotactic body radiation therapy (SBRT) in the management of adrenal metastases is emerging as a well-tolerated, effective method of treatment for patients with limited metastatic disease. SBRT planning and treatment utilization are widely variable, and publications report heterogeneous radiation dose fractionation schemes and treatment outcomes. The objective of this analysis was to review the current literature on SBRT for adrenal metastases and to develop treatment guidelines and a model for tumor control probability of SBRT for adrenal metastases based on these publications.

Brain Metastases: An Update on Multi-disciplinary Approach of Clinical Management.

Neurochirurgie 2021 Apr 14. Epub 2021 Apr 14.

Department of Neurosurgery, University of Wisconsin School of Medicine & Public Health, UW Carbone Cancer Center, Madison, WI, USA. Electronic address:

Importance: Brain metastasis (BM) is the most common malignant intracranial neoplasm in adults with over 100,000 new cases annually in the United States and outnumbering primary brain tumors 10:1.

Observations:  The incidence of BM in adult cancer patients ranges from 10-40%, and is increasing with improved surveillance, effective systemic therapy, and an aging population. The overall prognosis of cancer patients is largely dependent on the presence or absence of brain metastasis, and therefore, a timely and accurate diagnosis is crucial for improving long-term outcomes, especially in the current era of significantly improved systemic therapy for many common cancers.

Am J Hematol 2021 Apr 17. Epub 2021 Apr 17.

Neurology, APHP, Sorbonne Université, Paris, France.

The treatment of primary vitreoretinal lymphoma (PVRL) remains controversial regarding the use of local, systemic, or combined treatments. The aim of this study was to analyze the efficacy and toxicity of intravenous high-dose methotrexate (IV HD-MTX) based systemic therapy in a uniformly treated population of PVRL patients. From a nationwide French database, we retrospectively selected 59 patients (median age: 70 years, median Karnofsky Performance Status: 90%) with isolated PVRL at diagnosis who received first-line treatment with HD-MTX between 2011-2018.
