The total number of confirmed COVID-19 cases worldwide has surpassed 1.4 million. With varying public health responses across countries, there is still no clear prediction for when the number of cases will peak. This severe situation creates challenges for cancer patients who still need to receive treatment and daily medical care. The following advice from the Asian Fund for Cancer Research (AFCR) may offer guidance for cancer patients dealing with the current crisis:
- Stay at home! If you do need to go out, wear a face mask. Your immune function is weaker than healthy people [1-3]. Don’t take risks that might put you in dangerous conditions!
Special Note: An ounce of prevention is better than a pound of cure—and there is currently no cure for COVID-19.
- Don’t take hydroxychloroquine and chloroquine by yourself at home without getting specific guidance from your oncologist. [4-5].
Special Note: Some cancer patients already have these drugs at home from different channels. However, they should not be taken without the instruction and guidance from your physician. Circulating information that these drugs are sure to kill coronavirus and keep you from being hospitalized is simply false.
- Call your oncologist to ask if you can keep your treatment appointment schedule .
Special Note: Delayed surgery, chemotherapy, radiation therapy or screening activities (e.g. mammography for early diagnosis of breast cancer) may lead to disease progressions and result in worse survival outcomes. Try your best to maintain your scheduled appointments or to promptly reschedule your appointments when the epidemic slows its pace.
- If you have a stable cancer, consult with your oncologist to see if you need to postpone your adjuvant chemotherapy or elective surgery.
Special Note: The risk of exposure to coronavirus significantly increases at hospitals where large numbers of COVID-19 patients are being treated . Therefore, an intentional postponing of adjuvant chemotherapy or elective surgery for a stable cancer might be an option considered by your oncologist. This decision will be highly patient- and location-specific, so it is important to have a detailed discussion with your doctor.
