Salivary gland carcinomas (SGC) are a rare and variable group of head and neck cancers with historically poor response to cytotoxic chemotherapy and immunotherapy in the recurrent, advanced, and metastatic settings. In the last decade, a number of targetable molecular alterations have been identified in SGCs including HER2 upregulation, androgen receptor overexpression, Notch receptor activation, NTRK gene fusions, and RET alterations which have dramatically improved treatment outcomes in this disease. Here, we review the landscape of precision therapy in SGC including current options for systemic management, ongoing clinical trials, and promising future directions.
Coronavirus disease 2019 (COVID-19) can cause acute respiratory distress syndrome (ARDS) that is associated with high mortality among patients requiring invasive mechanical ventilation. We present a case of a 56-year-old male with hypertension and obesity who presented with chest pain from COVID-19. The patient required endotracheal intubation due to worsening hypoxia and remained intubated for 33 days. Tracheostomy placement was delayed in part due to persistent COVID-19 positive testing until hospital day 37. The patient required a total of 52 days in the ICU prior to discharge to a rehabilitation facility. This case highlights the extensive resources needed for critically ill patients with COVID-19 and the long duration that patients may test positive for the virus after onset of symptoms. It also raises questions about the timing and safety of tracheostomy placement among those patients requiring mechanical ventilation from COVID-19.
Combination treatment regimens including a proteasome inhibitor (PI), an immunomodulatory agent (IMiD) and a corticosteroid are standards of care for initial treatment of multiple myeloma (MM). We aimed to evaluate if a sequential treatment program using PI induction followed by IMiD based consolidation and maintenance could achieve similar outcomes with reduced toxicities. This phase 2 study was designed to assess the safety and efficacy of the Car-BiRd regimen: carfilzomib and dexamethasone (Kd) induction until maximum response, followed by lenalidomide, clarithromycin and dexamethasone (BiRd) consolidation until next maximum response, then lenalidomide maintenance in patients with newly diagnosed MM. Seventy-two patients, including both transplant eligible and ineligible patients, were enrolled and evaluated for response. The overall response rate to the Car-BiRd regimen was 94% with 83% of patients achieving a ≥ VGPR and 35% achieving a CR/ sCR. The rate of CR/sCR increased from 7% with Kd induction to 21% with BiRd consolidation and 35% with lenalidomide maintenance. These results did not meet the study's target endpoint of a CR rate of 55%. The median PFS using this deferred transplant approach was 37.3 months (95% CI 27.9, 52.7) and median OS was not reached with a median follow-up of 60 months. Toxicities were primarily low grade and manageable. Hematologic toxicities were lower than those expected with a combination PI/IMiD protocol. The sequential Car-BiRd regimen is an effective and safe approach for the upfront treatment of MM including patients unfit for transplant.
Lenalidomide is an IMiD drug which has been associated with a variety of potential immune related complications. We describe the case of a patient with newly diagnosed multiple myeloma along with a history of systemic mastocytosis who developed evidence of an autoimmune enteropathy shortly after initiating lenalidomide based therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
