De-escalation of surgical and radiation treatment in elderly luminal breast cancer patients, single institution report and review of the evidence.

Background: De-intensification of anti-cancer therapy without significantly affecting outcomes is an important goal. Omission of axillary surgery or breast radiation is considered a reasonable option in elderly patients with early-stage breast cancer and good prognostic factors. Data on avoidance of both axillary surgery and radiation therapy (RT) is scarce and inconclusive.

Squamous cell carcinoma arising in chronically damaged skin (Marjolin's Ulcer): still an unmet need in the era of immunotherapy.

Background: Cutaneous squamous cell carcinoma (cSCC) is characterized by a high tumor mutational burden due to solar damage and a favorable response to anti-PD-1 immunotherapy. Yet, we encounter tumors arising in areas with minimal sun exposure, such as cSCC that develops in chronically inflamed skin, also known as Marjolin's Ulcer (MU). The response of MU-SCC to immunotherapy remains unknown.

The effect of long-standing lymphopenia after radiation therapy on survival in rectal cancer.

Background: Lymphopenia and high neutrophil-to-lymphocyte ratio are known negative prognostic factors in rectal cancer. Until recently, however, lymphopenia was regarded as a minor sequela following radiation therapy (RT). The immune system's influence on rectal cancer treatment outcomes led us to evaluate the impact of lymphopenia at various time points, before, during, and following radiotherapy.

The prognostic value of beta-1 blockers in patients with non-small-cell lung carcinoma treated with pembrolizumab.

Background: Immune checkpoint inhibitors (ICIs) such as pembrolizumab have revolutionized the treatment of metastatic non-small cell lung cancer (mNSCLC). Beta-adrenergic activation contributes to cancer initiation and progression. While non-selective beta-blocker were found to improve the efficacy of ICIs therapy, the role of beta-1 (β)-selective -blocker (βB) in lung cancer patients is unknown.

Association between diabetes mellitus and reduced efficacy of pembrolizumab in non-small cell lung cancer.

Background: Diabetes mellitus (DM) is a highly prevalent chronic metabolic disorder. Although DM has been associated with immune dysfunction, the effect of DM on the efficacy of immunotherapy is unknown. This study aimed to evaluate the impact of DM on the efficacy of pembrolizumab in metastatic non-small cell lung cancer (NSCLC).

Real-life daily activity: the impact of misbeliefs on quality of life among cancer patients.

Background: While side-effects and health-related quality of life (QoL) are routinely assessed in clinical trials, commonly used tools do not measure patients' ability to maintain normal daily activities. QoL can be severely affected directly by the disease, the treatment side-effects and by personal and societal misconceptions promoting avoidance from activities perceived as dangerous for cancer patients. We examined practices of actively treated patients with cancer.

Immunogenicity and Safety of the BNT162b2 mRNA COVID-19 Vaccine Among Actively Treated Cancer Patients.

Background: Activity and safety of the SARS-CoV-2 BNT162b2 vaccine in actively treated patients with solid tumors is currently unknown.

Methods: We conducted a retrospective study of 326 patients with solid tumors treated with anticancer medications to determine the proportion of cancer patients with immunogenicity against SARS-CoV-2 following 2 doses of the BNT162b2 vaccine. The control group comprised 164 vaccinated healthy adults.

Rapid Implementation of Telemedicine During the COVID-19 Pandemic: Perspectives and Preferences of Patients with Cancer.

Introduction: The use of telemedicine in oncology practice is rapidly expanding and is considered safe and cost effective. However, the implications of telemedicine on patient-physician interaction, patient satisfaction, and absence of the personal touch have not been studied to date. Following the spread of COVID-19, telemedicine services were rapidly incorporated at the Oncology Division of Tel Aviv Medical Center.
