| Popis: | e18753 Background: Vaccination against COVID-19 decreases the risk of severe COVID 19 disease, hospitalization and death. Despite widespread recommendation from different cancer societies, vaccine hesitancy remains an issue in developing countries. Methods: Records of patients with cancer who received COVID-19 vaccination from March 1, 2021 and December 1, 2021, at Todua Clinic were analyzed retrospectively. Patient reported adverse effects (AE), vaccine related treatment interruptions, COVID -19 infection, and hospitalization rates were recorded. Results: A total of 1728 patients with cancer were treated at Todua Clinic during the study period. Of 177 (10%) patients who received Covid-19 vaccine, 63% were female and 34% were male. All patients were White. Mean age was 62 years. Majority of patients had solid cancer (93%) and only 7% had hematologic malignancies. A total of 76 (43%) patients had metastatic disease. Nearly half (47%) of patients were receiving cytotoxic chemotherapy, while others were receiving different treatment modalities (hormone therapy (33%), concurrent chemo-radiation (9%), chemo-immunotherapy (4%), targeted therapy (3%), immune therapy (2%), radiation therapy (2%)). Majority of the patients were vaccinated during the treatment process (61%), while 18% received covid-19 vaccine prior to treatment initiation and 21% patients received the vaccine after completion of treatment. A total of 124 patients (70%) were vaccinated with Pfizer-BioNTech, 33(19%) patients had received Sinopharm (Beijing), 14(8%) patients were vaccinated with The Oxford/AstraZeneca and 6 (3%) patients with Sinovac/CoronaVac. Only 13 (7%) patients received a booster dose (BD). Injection site pain was main AE for all vaccines (AstraZeneca 50%, Pfizer 33%, Sinopharm 45%, Sinovac 50%). Fever was reported in 14% of patients vaccinated with AstraZeneca, and 2% of those who received Pfizer vaccine. There were isolated cases of lymphadenopathy, fatigue, loss of appetite, joint and muscle pain after Pfizer vaccine and one case of polyneuropathy after a booster dose (Pfizer). No treatment interruptions were attributed to vaccination. Only 23 patients (13%) had confirmed COVID-19 infection (post AstraZeneca 1, Pfizer 13, Sinopharm 8, Sinovac 1). Only 1 case of hospitalization was reported after Sinopharm vaccine. No death was reported due to COVID-19 infection. Majority of patients (80%) were vaccinated following recommendation from their treating oncologist. Conclusions: In our study, COVID-19 vaccination was found to be safe for patients with cancer, and performed well with only one COVID-19 related hospitalization and no deaths. Vaccination rates among cancer patients are marginal in Georgia, and institutional and national policies are needed. |
