    Abstract As we know more about the clinical and laboratory features of COVID-19, which is now accepted as a pandemic, many questions have been raised about how to manage and monitor the treatment of cancer patients. It was determined that the incidence of lymphopenia increased in COVID-19 and there was a significant relationship between lymphopenia and mortality. This can be thought of as an unresponsive problem in how to maintain anti-cancer drugs that cause lymphopenia. This article was written for a hypothetical approach in cancer patients diagnosed with COVID-19 in order to be an idea of collecting data for treatment with anti-cancer drugs that cause lymphopenia.

    Abstract Sarcomas probably develop after malignant transformation of embryonic mesenchymal cells and have broad spectrum histopathologically since they can develop from striated skeletal muscle and smooth muscle, fat and fibrous tissue, bone, cartilage and other mesenchymal tissues. The most common histological subtypes of soft tissue sarcoma in adults are: liposarcoma, leiomyosarcoma, poorly differentiated pleomorphic sarcoma, and gastrointestinal stromal tumor. Molecular and genetic studies of soft tissue sarcomas, which are considered as heterogeneous groups in terms of their molecular and clinical characteristics, are still an important area of ​​interest The heterogeneity of the molecular and genetic alterations of these malignancies, which are mostly treated with surgery and chemotherapy, also offers hope to the researchers in terms of treatment targets. In this article, molecular biologic features of the soft tissue sarcomas including liposarcoma, rhabdomyosarcoma, leiomyosarcoma, synovial sarcoma, and angiosarcoma are discussed in the light of recent developments in molecular biology, targeted therapies and immunotherapy.

    Abstract Self-esteem is a way of coping with stress for cancer patients and this improves their quality of life. It was aimed to determine the relationship between type A personality traits and self-esteem and quality of life in women with breast cancer and to determine the effective factors. 154 women with breast cancer and 78 healthy women were included. Bortner's Rating scale, Rosenberg's Self-Esteem scale, and EORTC QOL-C30 scale were used. The relationship between the presence of hobbies, self-esteem, quality of life, and personality type was examined. Mann-Whitney U, Kruskal-Wallis, Fisher's Exact, and Spearman Rank correlation tests were performed. Independent factors affecting personality type, self-esteem, and quality of life were determined by multivariate logistic (binary) regression analysis. The p < 0.05 value was significant in the SPSS v19 program. There was no age difference between the patients (54 ± 11 years) and the control group (42 ± 8 years) (p = 0.108). The rate of type A personality was 69% in patients and 58% in controls (p = 0.093). Similarly, the rate of high self-esteem was 93% in patients and 96% in controls (p = 0.098). Besides personality type and self-esteem, there was no relationship between personality type and quality of life in cancer patients (p = 0.960 and p = 0.946, respectively). A relationship was established between self-esteem and quality of life (p = 0.018) in patients. In patients with type A personality, hobbies providing socially active communication were common (p = 0.039), and had more than two hobbies (p = 0.015). Type A personality trait was independently effective on self-esteem (p = 0.046). Hobby orientation and the number of hobbies had independent effects on self-esteem (p = 0.032, p = 0.041), quality of life (respectively, p = 0.004, p = 0.007), and personality type (respectively, p = 0.014, p = 0.027). Hobbies that provide active social communication may have important effects on changes in personality traits, self-esteem, and quality of life in patients with breast cancer.

    Abstract Background: Music and medicine can be used in patients with cancer as a palliative complementary therapy. It is aimed to show the effect of music therapy performed on anxiety, depression, and chemotherapy-related nausea/vomiting.
    Methods: A total of 62 patients with colon cancer who previously experienced grade 1 or 2 chemotherapy-related nausea and vomiting were divided into two groups as intervention and control group based on the addition of music and medicine to infusion chemotherapies and 1:1 randomized. The groups were compared in terms of the effect of music and medicine on anxiety, depression, heart rate, blood pressure, and chemotherapy-related nausea-vomiting. Statistical analysis was done using SPSS Statistics for Windows, Version 19.0. A value of P < 0.05 was found statistically significant.
    Results: The patients were evaluated in terms of study variables at the beginning and after the completion of a chemotherapy session. As a result, there was a significant decrease in systolic blood pressure (P = 0.042), diastolic blood pressure (P = 0.44), heart rate (P = 0.046), state and trait sections of the state-trait anxiety inventory scores (P = 0.047 and P = 0.046, respectively), as well as a significant decrease in anxiety degree (P = 0.036) and a significant improvement in chemotherapy-related nausea (P = 0.021) and vomiting (P = 0.038) experience in the intervention group. However, no significant effect of music and medicine on depression was detected (P = 0.218).
    Conclusion: Although it has not been shown to have an effect on depression, it was concluded that music and medicine with classical music integrated into the chemotherapy session can reduce the degree of nausea/vomiting and anxiety levels.

    Abstract Chemotherapy-induced thrombocytopenia (CIT) is the most important cause of thrombocytopenia in cancer patients. In this paper, I discussed the effect of ABO blood group on CIT in patients with stage III colon cancer. In a pilot study, a total of 131 (72 men, 55 %) eligible patients with stage III colon cancer were divided into two groups according to whether they had CIT. Both groups were compared using demographic, histopathological, and laboratory variables. CIT was detected in 51 (40 %) of 131 patients. The incidence of CIT had a significant increased in patients with 0 blood group compared to other blood groups. It was concluded that the relationship between blood group 0 and the presence of CIT in patients with stage III colon cancer is independent of other study variables (P = 0.035, OR 3.14, 95 % CI 1.16-7.01). In conclusion, I hypothesized that 0 blood group may predict to differentiate high-risk patients for CIT.

    Abstract 5-Fluorouracil is a widely used cytotoxic chemotherapeutic agent in the treatment settings particularly in patients with gastrointestinal cancer. Various studies on the cardiac adverse effects of 5-fluorouracil, reported the likelihood of altered myocardial contractility and vascular endothelial damage caused by this agent. However, the mechanism underlying 5-fluorouracil-related cardiotoxicity is not clear. In certain experimental studies, thrombotic processes occurring in microvascular field were supposed to play a role in this condition. In the light of this knowledge, the administration of 5-fluorouracil may be considered to cause renal vascular endothelial damage that may result in the altered endothelial permeability. As a result of endothelial dysfunction, increased urinary albumin excretion may be in question and no study investigating this potential direct relationship has been available in medical literature. Based on this evidence, the hypothesis of that 5-fluorouracil might cause renal vascular dysfunction and microalbuminuria, was discussed in this article along with the basic knowledge.
