Antibody Response to COVID-19 mRNA Vaccine in Patients With Lung Cancer After Primary Immunization and Booster: Reactivity to the SARS-CoV-2 WT Virus and Omicron Variant.

Purpose: To examine COVID-19 mRNA vaccine-induced binding and neutralizing antibody responses in patients with non-small-cell lung cancer (NSCLC) to SARS-CoV-2 614D (wild type [WT]) strain and variants of concern after the primary 2-dose and booster vaccination.

Methods: Eighty-two patients with NSCLC and 53 healthy volunteers who received SARS-CoV-2 mRNA vaccines were included in the study. Blood was collected longitudinally, and SARS-CoV-2-specific binding and neutralizing antibody responses were evaluated by Meso Scale Discovery assay and live virus Focus Reduction Neutralization Assay, respectively.

Two distinct histological Richter's transformations 23 years apart in a patient with chronic lymphocytic leukaemia.

A 53-year-old man with a 1-year history of chronic lymphocytic leukaemia (CLL) presented with a left bicep mass. Biopsy and staging workup revealed Richter's transformation (RT) Ann Arbor stage 1E diffuse large B-cell lymphoma in the bicep. The patient was treated with combination chemotherapy with cyclophosphamide, doxorubicin, Vincristine and prednisone followed by site radiation and did well thereafter.

Directed Therapies in Anaplastic Lymphoma Kinase-rearranged Non-small Cell Lung Cancer.

Anaplastic lymphoma kinase (ALK) rearrangements were first implicated as driving mutations in non-small cell lung cancer in 2007. Since then, a number of novel, small-molecule inhibitors directed against the ALK receptor have demonstrated superiority over standard chemotherapies in the treatment of ALK rearrangement-positive lung cancer. Of considerable importance when considering such therapies is the ability of each to overcome mutations conferring acquired resistance, as well as penetrate the central nervous system (CNS), the most common site of metastasis and traditionally the most difficult to breach.

Abiraterone is effective and should be considered for the treatment of metastatic castrate-naïve prostate cancer.

Androgen deprivation therapy (ADT) has been the standard of care for the treatment of newly diagnosed metastatic prostate cancer for the past 70 years. Furthermore, adding docetaxel chemotherapy to ADT significantly improved patient survival, and thus became the new standard for patients with high volume disease. However, recent evidence has called this treatment strategy into question since a published study has shown that the drug abiraterone has a similar benefit to docetaxel in a similar patient population group but with less toxicity.
