Abstract:
e15570 Background: Ramucirumab is the first anti-angiogenic targeted agent to demonstrate improved survival as monotherapy or in combination with CT among patients with disseminated stomach cancer. Methods: Under our supervision there were 24 patients: 12 men (50%) and 12 women (50%), from 29 to 72 years old, the median age was 52 years (95% CI 43.56-60.32). The median time to diagnosis of the 4th stage of the disease was 2 months (95% CI 0-11.44). All patients received 1 line of treatment; the median duration of 1-line therapy was 5 months (95% CI 4.00-6.83). Results: The duration of therapy with ramucirumab ranged from 2 to 16 months; median duration was 5.0 months (95% CI 3.00-7.44). The therapy with ramucirumab in 11 patients (45.83%) was followed by SD, in 3 patients (12.50%) - PR, in 4 patients (16.67%) - PD, and in 6 patients (25 , 00%) assessment of the effectiveness of therapy was not conducted due to the deterioration of the general condition during treatment. Thus, the ORR was 58.33%. The median overall survival was 18 months (95% CI 14–23). In order to identify adverse factors affecting overall survival, we constructed a Cox's regression model showing the dependence of overall survival on unfavourable prognosis factors. In general, the constructed model was reliable - p = 0.0013. The gender of the patients (p = 0.0642), the time before staging the 4th stage of the disease (p = 0.4312) and the duration of the 1st line therapy (p = 0.8675) did not have a significant effect on the survival of patients. Such factors as the patients' age (p = 0.0121), the localisation of the primary tumor (p = 0.0441), the differentiation of the tumor (p = 0.0095), the fact of removal of the primary tumor (p = 0.0133) had a significant impact, general status on the ECOG scale (p = 0.0250), the presence of anemia (p = 0.0192), damage to the peritoneum (p = 0.0022) and damage to metastases of more than 3 organs (p = 0.0062). Conclusions: An increase in OS in patients who received a combination of ramucirumab and paclitaxel can be considered clinically significant for this patient population and will allow considering this therapeutic regimen as a new standard of second line treatment of patients with poor prognosis of gastric cancer.
