The Study
Case 1
- The first case was a 76-year-old female who was newly diagnosed with stage IIA cervical clear cell adenocarcinoma. The patient had a large cervical mass, measuring 10 cm. In February 2020, the patient had her first RT consult due to vaginal bleeding and underwent radiation therapy. During the radiation therapy treatment, the patient began showing difficulty breathing, with an ox…
Case 2
- The second case was a 70-year-old female who has unresectable squamous cell carcinoma of the vulva. The patient noted she had a painful vulvar bump, and after several scans, the doctor recommended RT. The patient started her treatment in March 2020 for five days. When she returned to therapy in April 2020, she was diagnosed with COVID-19 after developing shortness …
Case 3
- The third case was a 65-year-old female with stage IV endometrial carcinoma with sarcomatoid features. The patient was admitted to the hospital between April and May 2020. The patient’s cancer has already spread, and given her metastatic disease, palliative chemotherapy was proposed. The patient has undergone an RT course, but while being treated, she developed a co…
Case 4
- The last case was a 76-year-old male with prostate cancer. He received pelvic RT for his illness and had metastatic disease in 2015. In January 2020, he received his second RT course. Five months after, he tested positive with COVID-19 during a hospital admission due to back pain. The patient finished his RT treatment and responded with improved pain control. There were no adve…
Study Implications
- The study presented four cases of cancer patients who were subsequently diagnosed with COVID-19 and received RT. The researchers noted that these patients had outcomes that do not seem to be affected by the viral infection. In fact, the patients had no acute and unexpected adverse effects of RT. The researchers noted that the case study was the first to report COVID-19 infecte…
