The purpose to study the risk factors for elderly women with left breast cancer at the stage of chemotherapy and radiotherapy in the context of daily clinical practice for early detection of possible cardiovascular complications and optimization of therapy. Material and methods. 69 women with HER2 neu negative left breast cancer without severe cardiovascular disease were examined. The first group included 39 elderly patients (67.7 3.8 years). The second group consisted of 34 middle-aged patients (49.8 5.7 years). In addition to the risk assessment according to the Score scale, additional factors including psychosocial factors were studied. The examination was carried out before the start of treatment, after the end of the course of doxorubicin in a cumulative dose of up to 360 mg/m2 and after the completion of radiation therapy 3D conformal radiation therapy SOD 39 Gr. Results. In elderly patients, risk factors such as obesity, increased cholesterol, and hypertension were significantly more common. In both study groups, low physical activity was revealed associated with both cancer itself and the treatment. All examined patients had moderate reactive anxiety on the Spielberger-Hanin scale. Elderly patients showed high level of personal anxiety; the number of points scored 49.3 3.6. According to the Score scale, a moderate risk was detected in 18 (58.1%) and a high risk in 13(41.9%) elderly patients. After doxorubicin treatment asymptomatic systolic dysfunction was detected in 8 (20.5%) patients (decrease in EF50%), 21 (75%) diastolic dysfunction with relaxation slowdown (E/A1). In 9 (23.1%) of the women without reducing the EF fibrotic changes in the myocardium of the left ventricle was revealed. In 8 (20.5%) women a thickening of the pericardial layer was revealed. Conclusion. The findings suggest the need for a personalized approach and assessment of risk factors in patients of different age groups with left breast cancer at the stage of preparation and conduct of chemoradiotherapy. This highlights the need for enhanced history collection and consideration of not only key but also additional risk factors. The results of the study can be used in the work of practical health care institutions for the planning, development, implementation and control of chemoradiography safety in terms of preventing cardiovascular complications.
Материал посвящен новому междисциплинарному направлению «Кардиоонкология». Пациенты с онкологическими заболеваниями имеют повышенный риск развития сердечно -сосудистых осложнений, связанных с проводимой противоопухолевой терапией. В статье описаны исторические этапы применения противоопухолевого лечения, сопровождающегося возможным эффектом кардиотоксичности, представлено современное состояние проблемы и рассмотрены перспективы дальнейшего развития. Приведены данные российских и зарубежных исследований в этой области. The material is devoted to a new interdisciplinary direction “Cardioncology”. Patients with oncological diseases have an increased risk of developing cardiovascular complications associated with antitumor therapy. The article describes the historical stages of the use of antitumor treatment leading to the development of cardiotoxicity, presents the current state of the problem and considers the prospects for further development. The data of russian and foreign studies in this area are presented.
BACKGROUND: Arterial hypertension is one of the key risk factors for the development of cardiotoxicity in cancer patients. The importance for patients with left breast cancer is due to the possibility of the heart getting into the radiation area during treatment. The use of a method for assessing the quality of life and symptoms of anxiety can help improve treatment in such patients by increasing the interaction between a physician and a patient. AIM: The aim of the study is to assess the quality of life and the level of anxiety in patients with breast cancer, depending on the presence of arterial hypertension. MATERIALS AND METHODS: 67 patients with HER2neu negative cancer of the left breast have been examined. The average age is 42 (47; 63). All the patients after radical mastectomy and a course of chemotherapy with the inclusion of doxorubicin in a cumulative dose of no more than 360 mg/m2 have been hospitalized for 3D conformal radiation therapy. The first group included 32 patients with grade III comorbid hypertension; the second group included 35 patients without hypertension. The examination included an assessment of the status of an oncological patient according to the ECOG scale, echocardiography with an assessment of diastolic function, determination of the level of reactive and personal anxiety according to the Spielberger Khanin scale and quality of life using the SF-36 questionnaire. RESULTS: In the group of the patients with combined hypertension, left ventricular hypertrophy has been detected in 48 % of cases. In the patients of both groups with preserved ejection fraction, type I diastolic dysfunction has been detected (E/A 1): in the patients of the first group in 59.4 % of cases, in the patients of the second 31.4 % of cases. The difference obtained is due to the effect of hypertension on the left ventricular relaxation disorder. The level of reactive anxiety was significantly higher in the patients of the first group and amounted to 43.8 (41.2; 46.2) versus 38.4 (32.7; 42.6) points in the second group. The level of personal anxiety was high in the patients of both groups, which can be explained by the predominant influence of cancer. In the patients of both groups, there was a decrease in indicators according to the SF-36 questionnaire on all scales. The most significant changes have been obtained on the scales of physical functioning, role-based physical functioning, pain, vitality and general health. Cancer patients with concomitant hypertension rated their health status lower, while they are more likely to note a decrease in daily role activity as a result of their emotional state. CONCLUSIONS: The data obtained indicate that arterial hypertension has a significant negative effect on the level of reactive anxiety and quality of life indicators of breast cancer patients, which is of great importance in the formation of a patient-oriented approach to the therapeutic support of specific treatment in such patients.
Purpose. Detection of adherence to a healthy lifestyle (HLS) and evaluation of behavioral risk factors for cardiovascular complications (CVC), including psychosocial, in patients with left breast cancer at the stage of chemoradiotherapy in daily clinical practice. Materials and methods. The patients were hospitalized for 3D conformal radiation therapy on the bed of the left breast with a total radiation dose (TRD) of 39 Gy (equivalent to 48 Gy of conventional fractionation). All the patients had a Madden mastectomy at the previous stages followed by doxorubicin therapy at a cumulative dose not exceeding 360 mg/m2. Determination of all components of a healthy lifestyle was carried out according to the data of interviewing the participants. The risk category of cardiovascular complications was assessed according to the SCORE scale. Additional characteristics including psychosocial factors were assessed. The examination included ECG and echocardiography. Results. At the initial examination, 58% of middle-aged patients and 74% of elderly patients showed comorbidity, while 18% of middle-aged patients and 29% of elderly patients had multiple comorbidities. Low adherence to healthy lifestyle in the patients was primarily associated with low physical activity due to the existing pain syndrome caused by both the tumor process itself and the surgical intervention. Physical activity in both groups was significantly lower than in the general population. High risk of CVC was significantly more common in the elderly patients. Systolic and diastolic dysfunction as a manifestation of cardiotoxicity after the previous stage of doxorubicin therapy were detected in middle-aged patients in 35.7% of the cases, in the elderly patients in 56.5% of the cases (HR 0.643, 95% CI 0.470-0.880). Psychosocial factors such as acute chronic stress and family problems were the most common. All the examined patients showed moderate reactive anxiety. The elderly patients showed a high level of personal anxiety. Conclusions. The obtained data suggest that in breast cancer patients, low adherence to HLS is primarily associated with low physical activity and unhealthy diet and to a much lesser extent smoking, which is of great importance in the formation of a healthy lifestyle in these patients in the future. In elderly patients, the study significantly more often identified risk factors such as obesity, high blood pressure, hypercholesterolemia and hyperglycemia. These patients revealed increased level of personal anxiety. This highlights the need for an expanded study of not only the main but also additional risk factors.
