Case report of partial response on second line with Ramucirumab and FOLFIRI in treatment of 74 year old male with metastatic HER2-negative gastric adenocarcinoma

Abstract

According to the data of the world statistics, gastric cancer (GC) occupies the 5th place by morbidity and the 3rd one by mortality among malignant neoplasms. A significant proportion of patients are elderly patients, the proportion of which in real clinical practice can reach up to 60%. Ramucirumab is among the standards of second-line drug therapy both in monotherapy and in combination with paclitaxel. The feasibility of prescribing ramucirumab to patients with disseminated cancer of the elderly and its satisfactory tolerability is shown in a subgroup analysis of the REGARD and RAINBOW studies. The use of paclitaxel, included in the standard first-line regimens, may be limited by persistent neurotoxicity, a side effect of platinum derivatives. In this regard, the effectiveness of the combination of ramucirumab with the FOLFIRI regimen as a second-line therapy began to be studied. The article presents a clinical case of achieving a partial effect on the second-line therapy with ramucirumab with FOLFIRI regimen in a 74-year-old patient with HER2-negative gastric adenocarcinoma while registering rapid progression after 4 courses of first-line chemotherapy in XELOX regimen. Tolerability of the second line was acceptable: asthenia grade 1, stomatitis grade 1-2, neutropenia grade 3 were observed, so the irinotecan dose was reduced to 165 mg/m2. By June 2021, there were 10 28-day cycles of treatment, which is ongoing. The duration of disease control in the second line therapy was 11+ months, of which 9+ months – on the background of FOLFIRI regimen drug therapy with ramucirumab.
