[Possibilities of stereotactic radiotherapy in the palliative treatment of patients with pancreatic cancer].

Morbidity and mortality from pancreatic cancer is steadily increasing. Resectable cases are not more than 20%. Conventional schemes of chemoradiation and radiation therapy are durable over the time, have toxicity and low treatment outcomes. Many foreign authors consider as promising the technique of stereotactic radiotherapy, which is often used in pancreatic cancer and permit achieving high local control. At our institution there has been developed and introduced into clinical practice a method of stereotactic radiotherapy for the palliative treatment of patients with pancreatic cancer, which improved not only the duration but also the quality of life of patients.

[Complex treatment of breast cancer patients with brain metastases].

Brain metastases in breast cancer develop for 24-32 months after the detection of the primary tumor. The study included patients with brain metastases who were divided into three groups: the first group--with early chemoradiotherapy (CRT) without induction chemotherapy (IC) by capecitabine; the second group--with delayed CRT with 4 or 8 courses of IC by capecitabine; the third group (a historical control) who received only whole brain radiation therapy. The median time to progression of intracranial metastases was 15.3, 12 and 5 months, respectively. The median time to the intracranial progression significantly less in the third group (5 months) compared with the first (15.3 months) (p = 0.0007) and the second (12 months) (p = 0.027) groups. The overall survival rate was 22.1, 15.1 and 6.8 months in three groups, respectively.
