    Aim: To assess the anxiety levels of breast cancer patients during the COVID-19 pandemic. Materials & methods: A total of 298 patients completed the State-Trait Anxiety Inventory (STAI-S and STAI-T) and the Visual Analogue Scale for Anxiety (VAS) and VAS for Anxiety in COVID-19 (VAS-CoV). Results: 144 patients were in the high anxiety category for STAI-S, and 202 patients were in the high anxiety category for STAI-T. STAI-T score was significantly high in the metastatic group (p = 0.017). VAS-CoV score in the hormonotherapy group was significantly higher than in the no-treatment group (p = 0.023). There was a positive correlation between VAS-CoV and VAS levels (r = 0.708, p < 0.001), VAS-CoV and STAI-S and STAI-T scores (r = 0.402, p < 0.001; r = 0.185, p = 0.001, respectively), and a negative correlation between education years and STAI-T scores (r = -0.172, p = 0.003). Conclusion: The COVID-19 pandemic is related to high anxiety levels in breast cancer patients.

    Introduction Breast cancer is the most frequently diagnosed cancer in women worldwide. Ribociclib is now frequently used in the treatment of metastatic hormone-positive and human epidermal growth factor receptor 2 (HER 2)-negative breast cancer. Case Report A 54-year-old woman with breast cancer presented at a clinic in November 2017 with multiple lung and bone metastases. After receiving multiple lines of treatment due to disease progression, ribociclib and fulvestrant were initiated. Grade 4 toxicity was observed due to ribociclib during follow-up, and ribociclib was discontinued permanently. Management & Outcome: Given that liver transaminases and bilirubin elevation persisted despite discontinuation of the treatment, other reasons for liver toxicity were investigated. Abdominal MRI showed no liver metastases, although there was acute hepatitis. A liver biopsy was performed to determine the etiology. The pathology result was compatible with drug-induced acute fulminant toxic hepatitis. After liver biopsy, prednisolone treatment was initiated, after which the laboratory findings normalized. Discussion Although there are reported cases showing improvement in liver enzymes after ribociclib discontinuation, in our case, no recovery from hepatotoxicity was noticed. The treatment was changed to another hormonal pathway therapy option, exemestane. To the best of our knowledge, this is the first case in the literature reporting this rare side effect of ribociclib, which is a liver biopsy-proven fulminant hepatitis.

    The efficacy of BNT162b2 (Pfizer-BioNTech) and CoronaVac vaccines in patients with cancer

    Although vaccination is efficacious and prevents infection in the general population, there is limited data about Coronavirus disease-19 (Covid-19) occurrence after vaccination in cancer patients. It was aimed to evaluate the efficacy of BNT162b2 (Pfizer-BioNTech) and CoronaVac vaccines against Covid-19 in patients with cancer. In this single-center, retrospective, cross-sectional, and descriptive study, the data of cancer patients referred to the medical oncology clinic of a university hospital were analyzed. The sample of the study consisted of cancer patients who had Covid-19 or were vaccinated against Covid-19. A total number of 2578 patients were included in the study. Of the patients, 2000 have never been infected with severe acute respiratory syndrome coronavirus and 578 patients have had a positive reverse-transcription polymerase chain reaction (RT-PCR) for Covid-19. It was found that 2094 patients (81.2%) were fully vaccinated, and 484 patients (18.8%) did not receive full-dose vaccination. A statistically significant difference in Covid-19 occurrence was found between the patients who had full-dose vaccination or not (p = 0.000). In in-group comparisons of full-dose vaccinated patients, while no difference was observed between two doses of BNT162b2 (Pfizer-BioNTech) and three doses of CoronaVac (p = 0.432), a statistically significant difference was observed between all other groups (p < 0.005). When the data of 578 patients who experienced Covid-19 was analyzed, a statistically significant difference was observed between the groups who were full-dose vaccinated and those who were not (p = 0.000). It is recommended that this vulnerable patient group should be prioritized in vaccination programs, and full-dose vaccination (at least two doses of vaccines) should be completed as soon as possible.
