Treatment changes in prostate cancer patients on active treatment during the COVID-19 pandemic in a community cancer center in New York City.

Abstract

e18750 Background: The surge of the SARS coronavirus-2 (COVID-19) pandemic posed great challenges in the oncology community for optimal management of cancer patients. We sought to analyze the treatment changes experienced by the prostate cancer patients in March, April and May 2020 and to compare these treatment decisions to the published guidelines. Methods: We focused on patients currently receiving androgen deprivation therapy (ADT) with leuprolide acetate, and/or oral anti-androgen agents (Androgen receptor axis targeted agent, ARAT), or chemotherapy. Electronic medical records were reviewed, and the oncologists and nurse practitioners were interviewed to understand the decision-making process. Results: Seventy-five patients were included, median age 72 years old (range 47-95). All were taking ADT, and 21 were also taking ARAT, and 3 were also receiving chemotherapy. The incidence and indications for their ADT treatments and schedule changes are shown in the table below. Twenty-seven patients (36%) experienced delays in their ADT treatment, and the percentage of treatment change was similar in categories of metastatic hormone sensitive prostate cancer (mHSPC), metastatic castration resistant cancer (mCRPC), biochemical recurrence as well as stage IVA post surgery. Four patients were receiving neoadjuvant ADT planned prior to definitive radiation, and none had schedule change. One patient with mHSPC and 2 patients with mCRPC continued chemotherapy as planned. One patient declined recommended chemotherapy for mCRPC. Two patients were given q 3 months dose of ADT instead of q 1m, while all the rest were already receiving q3 months dosing. Among the 27 patients who had schedule change, 12 (44.4%) patients had a discussion with their providers first, and 15 patients (55.6%) did not keep their treatment appointment. Conclusions: About one third of patients changed ADT injection schedule with a similar percentage in patients with mHSPC, or mCRPC or Biochemical recurrence, or IVA after surgery. Every 3 months dosing of ADT recommended by NCCN significantly decreases exposure to COVID -19, delaying or skipping treatment was still encountered due to health concern or travel limitations. On the other hand, all patients receiving neoadjuvant ADT, or chemotherapy stayed on schedule. Although NCCN guideline recommended delaying myelosuppressive therapy, palliative chemotherapy for symptomatic, refractory patients may still be a priority.[Table: see text]
