[Therapeutic Effect and Adverse Events of Ramucirumab in Patients with Gastric Cancer in Our Hospital].

From January 2016 through December 2017, 18 patients received paclitaxel plus ramucirumab combination therapy and 1 patient received ramucirumab monotherapy. Thus, a total of 19 patients were analyzed in terms of both therapeutic effect and adverse events. The response evaluation of the targeted lesion was as follows; CR: 0, PR: 1, SD: 16, PD: 2. The median of overall survival and progression-free survival of the combination therapy was 9.9 months and 4.2 months, respectively. Although more than half of the patients were enforced after tertiary therapy in our department, the therapeutic effect of paclitaxel plus ramucirumab combination therapy was considerably satisfactory. Neutropenia as an adverse event was observed in 13(68.4%)out of 19 patients, and 8 patients(42.1%)had neutropenia greater than Grade 3. Non -hematologic toxicity was observed in 17 cases(89.5%), and anorexia, nausea, diarrhea, dysgeusia, peripheral neuropathy, hair loss, and fatigue were determined to be either Grade 1 or 2. Alternatively, 1 patient developed Grade 3 interstitial pneumonia, and 3 patients(15.8%)had complicated Grade 3 high blood pressure. Only 2 patients who had severe adverse events, one was interstitial pneumonia and the other was high blood pressure, discontinued paclitaxel plus ramucirumab combination therapy.

Malignant lymphoma occurring in the residual stomach following gastrectomy: plus discussion based on the literature in Japan.

Malignant lymphoma of the remnant stomach was diagnosed in a 53-year-old man 8 years after gastrectomy for a perforated gastric ulcer. Endoscopic examination demonstrated protruding lesions spreading over the entire residual stomach, and biopsy revealed malignant lymphoma. Rectal cancer was diagnosed simultaneously. The residual stomach was completely excised, with splenectomy, in parallel with low anterior resection of the rectum. Histological studies revealed that the lesion in the residual stomach was a lymphoma of the diffuse, large-cell type, according to the Lymphoma-Leukemia Study Group (LSG) classification, with positivity for CD20 and CD45RA, leading to a diagnosis of B-cell lymphoma. Helicobacter pylori microorganisms were found on the luminal surface of the tumor. Despite postoperative chemotherapy, the patient died of disseminated lymphoma 34 months later. Although malignant lymphoma occurring in the residual stomach following gastrectomy is rare, particular attention should be given to the possible presence of a malignant tumor when examining the residual stomach following gastrectomy.
