Chemotherapy Treatment Modifications During the COVID-19 Outbreak at a Community Cancer Center in New York City.

ABSTRACT

PURPOSE: As a result of their immunocompromised status associated with disease and treatment, patients with cancer face a profound threat for higher rates of complications and mortality if they contract the coronavirus disease 2019 infection. Medical oncology communities have developed treatment modifications to balance the risk of contracting the virus with the benefit of improving cancer-related outcomes. METHODS: We systemically examined our community cancer center database to display patterns of change and to unveil factors that have been considered with each decision. We studied a cohort of 282 patients receiving treatment and found that 159 patients (56.4%) had treatment modifications. RESULTS: The incidence of treatment modification was observed in patients undergoing adjuvant and neoadjuvant (41.4%), palliative (62.9%), or injectable endocrine or bone-modulating only (76.0%) treatments. Modifications were applied to regimens with myelosuppressive (56.5%), immunosuppressive (69.2%), and immunomodulating (61.5%) potentials. These modifications also affected intravenous (54.9%) and subcutaneous injectable treatments (62.5%) more than oral treatments (15.8%). Treatment modifications in 112 patients (70.4%) were recommended by providers, and 47 (29.6%) were initiated by patients. The most common strategy of modification was to skip or postpone a scheduled treatment (49%). Among treatment with no modifications, treatment regimens were maintained in patients who tolerated treatment well (37.0%), in treatments with curative intent (22%), and in symptomatic patients who required treatment (14%). CONCLUSION: Our observation and analysis suggested that the primary goal of treatment modification was to decrease potential exposure. The pattern also reflected the negative impact of the pandemic on health care providers who initiated these changes. Providers have to consider individualized recommendations incorporating multiple factors, such as tolerance, potential toxicity, treatment nature and route, and disease severity.
