Multiple myeloma is a rare malignancy that exhibits a wide range of possible clinical presentations. In recent years, with the advent of stem cell transplantation, the prognosis of patients with multiple myeloma has been increasing. We searched the literature for reports of atypical myeloma presentations to aid clinicians in formulating differential diagnoses and to increase the number of cases diagnosed early. There have been a number of reports of early ocular symptoms, including, but not limited to, proptosis, optic neuropathy, vision loss, retinal hemorrhage, and detachment. Neurological presentations included cranial nerve palsies, vertigo related to cerebellar involvement, and diabetes insipidus related to pituitary involvement. Among gastrointestinal manifestations, there are a number of reports of multiple myeloma presenting as acute and chronic pancreatitis. Mesenteric ischemia due to amyloidosis, acute abdomen, and hepatosplenomegaly were also among reported presentations. When it comes to renal involvement, while acute renal failure and proteinuria are typical, there are reports of patients presenting with both nephritic and nephrotic forms of glomerular disease, as well as end-stage renal disease requiring dialysis. We believe that it is essential for clinicians to keep reporting atypical multiple myeloma presentations and consider it as a possible diagnosis in a patient with serious, atypical symptoms.
Extracorporeal membrane oxygenation (ECMO) is used to provide respiratory and/or circulatory support for critically ill patients. In people suffering from hematologic malignancies (HMs), acute respiratory failure often necessitates intensive care. Whereas initial studies reported that these patients generally have poor outcomes, studies conducted within the last 10 years have shown that ECMO is quite beneficial for patients with HMs. This review showcases data from 2010 to 2019 demonstrating the utility of ECMO in cancer patients. Retrospective studies revealed long-term disease-free survival, particularly when ECMO served as a bridge through chemotherapy. Case reports suggested strong evidence of mortality benefit from ECMO, especially in patients with aggressive lymphomas. However, a systematic approach is needed to better quantify and validate these findings. Studies with larger sample size and prospective cohorts are needed to help create well-defined guidelines for physicians approaching the treatment of cancer patients on ECMO.
The Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become the most talked-about clinical entity in early 2020. As an infection that spreads easily and has a significant mortality rate, it has caused global panic rarely seen before. Many of the measures taken by governments worldwide will have longlasting impacts on the wellbeing of the population at large. It has been widely reported that the most vulnerable patients have been most negatively affected by SARS-CoV-2 (COVID-19). In this study, we have tried to search the currently available data on the outcomes of infected cancer patients. Most of the data points to the very challenging nature of treating such patients. Their overall outcomes seem to be worse than in the general population, and it may be difficult to differentiate which potential complications are a result of the primary oncologic disease versus the infection. Management presents its own set of challenges, including but not limited to, deciding whether postponing cancer treatment until the infection resolves is going to benefit the patient and how to organize all aspects of patient care when social contact is as limited as it is for patients newly diagnosed with COVID-19. We believe that as more data becomes available, it is going to be necessary to publish detailed guidelines on how to approach this unique clinical challenge.
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.
