∅ Изучены исходные (до лечения) уровни VEGF в сыворотке крови 248 больных РМЖ в T1-2N0M0 стадиях и у 55 практически здоровых женщин (группа контроля). Средний показатель VEGF в сыворотке крови общей группы больных РМЖ достоверно выше, чем в контроле. При T2N0M0 стадии РМЖ отмечено более частое (25,0 %), по сравнению с T1N0M0 стадией (13,2 %), выявление повышенных уровней VEGF относительно его порогового значения (≥ 300 пг/мл). Полагаем, что показатель VEGF до лечения в сыворотке крови больных РМЖ при T2N0M0 стадии можно использовать с целью уточнения прогноза развития раннего (в первые 3 года наблюдения) рецидива заболевания как дополнительного маркера наряду с общепринятыми клинико-морфологическими признаками болезни.
Basal (pretreatment) serum VEGF levels were measured in 248 T1-2N0M0 breast cancer patients and 55 practically healthy women (control group). Mean VEGF level in the total group of breast cancer patients was significantly higher than in control. In T2N0M0 breast cancer patients serum VEGF concentrations exceeding the threshold level (300 pg/ml) were found more frequently (25 %) than in T1N0M0 patients (13 %). VEGF levels in breast cancer patients were not associated with their age and menopausal status, and tumor receptor (ER, PgR) status. VEGF levels were significantly higher in patients with lobular invasive cancer than in those with ductal cancer, and in patients with poorly differentiated cancer than in those with moderately and highly differentiated tumors. High (≥300 pg/ml) VEGF levels were more frequently found in breast cancer patients that relapsed in the first 3 years of follow-up than in patients with no relapse during this period (p = 0.001). We suggest that pretreatment serum VEGF determination in T2N0M0 breast cancer patients could be used for adjustment of early (in the first 3 years) relapse prognosis as a complement marker to traditional clinico-pathological disease characteristics.
