according to an editorial set to be published in European Urology.

“Regimens with a clear survival advantage should be prioritized, with curative treatments remaining mandatory,” wrote Silke Gillessen Sommer, MD, of Istituto Oncologico della Svizzera Italiana in Bellizona, Switzerland, and Thomas Powles, MD, of Barts Cancer Institute in London.
However, it may be appropriate to stop or delay therapies with modest or unproven survival benefits. “Delaying the start of therapy ... is an appropriate measure for many of the therapies in urology cancer,” they wrote.
Timely recommendations for oncologists
The COVID-19 pandemic is limiting resources for cancer, noted Zachery Reichert, MD, PhD, a urological oncologist and assistant professor at the University of Michigan, Ann Arbor, who was asked for his thoughts about the editorial.
Dr. Zachery Reichert
Oncologists and oncology nurses are being shifted to care for COVID-19 patients, space once devoted to cancer care is being repurposed for the pandemic, and personal protective equipment needed to prepare chemotherapies is in short supply.
Meanwhile, cancer patients are at increased risk of dying from the virus (Lancet Oncol. 2020;21:335-7), so there’s a need to minimize their contact with the health care system to protect them from nosocomial infection, and a need to keep their immune system as strong as possible to fight it off.
To help cancer patients fight off infection and keep them out of the hospital, the editorialists recommended growth factors and prophylactic antibiotics after chemotherapy, palliative therapies at doses that avoid febrile neutropenia, discontinuing steroids or at least reducing their doses, and avoiding bisphosphonates if they involve potential COVID-19 exposure in medical facilities.
The advice in the editorial mirrors many of the discussions going on right now at the University of Michigan, Dr. Reichert said, and perhaps other oncology services across the United States.
It will come down to how severe the pandemic becomes locally, but he said it seems likely “a lot of us are going to be wearing a different hat for a while.”
Patients who have symptoms from a growing tumor will likely take precedence at the university, but treatment might be postponed until after COVID-19 peaks if tumors don’t affect quality of life. Also, bladder cancer surgery will probably remain urgent “because the longer you wait, the worse the outcomes,” but perhaps not prostate and kidney cancer surgery, where delay is safer, Dr. Reichert said.
Prostate/renal cancers and germ cell tumors
The editorialists noted that oral androgen receptor therapy should be preferred over chemotherapy for prostate cancer. Dr. Reichert explained that’s because androgen blockade is effective, requires less contact with health care providers, and doesn’t suppress the immune system or tie up hospital resources as much as chemotherapy. “In the world we are in right now, oral pills are a better choice,” he said.
