e15505 Background: Inflammation seems to be significant factor in carcinogenesis and tumor progression of numerous cancers. Blood calculated neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP), lactate dehydrogenase (LDH), international normalized ratio (INR) can be evaluated as systemic inflammation markers and prognostic biomarker for many aims: survival outcomes, lymph node metastasis and recurrence, treatment responses in a variety of cancers. The purpose of this study was to investigate baseline associations between blood test parameters (NLR, PLR, LDH, CRP, INR) and their prognostic biomarker role for patient with metastatic gastric cancer, undergoing first-line chemotherapy Methods: Potential baseline inflammatory markers (platelets, neutrophils, lymphocytes, the platelet-lymphocyte ratio, the neutrophil-lymphocyte ratio, the serum C-reactive protein [CRP], the serum LDH, INR) were retrospectively analyzed in 32 patients with metastatic gastric cancer, IV stage (median of age – 60,50). Multivariate analyses were used to identify prognostic factors for overall survival (OS). Baseline values were compared with tumor characteristic and median survival times (MSTs). Results: Multivariate analysis identified due to Cox proportional-hazards regression showed significant longest OS in patients with: localization of primary tumor in antral part of gastric (HR 0,45, 95% CI 0,25-0,80, p = 0,0065); low baseline’s level of WBC (HR 1,17, 95% CI 1.02 - 1,35, p = 0,0219); low baseline’s level of neutrophil (HR 1,18, 95% CI 1.02 - 1,34, p = 0,0251). Level of LDH, CRP, INR didn’t show significant ratio for this cohort of patient. Peritoneum metastatic also didn’t significant affect on OS in patient with metastatic gastric cancer. Patients with low baseline’s platelet to lymphocyte ratio (HR 1,004, 95% CI 1,0009-1,0072, p = 0,0125) and low (from 0 to 3,0) neutrophil to lymphocyte ratio (HR 1,81, 95% CI 1,09-2,99, p = 0,0212) had a significantly longest OS time. Conclusions: Inflammatory markers can predict overall survival in stage IV gastric cancer. Simple and useful.
The purpose of the research. To study prognostic significance of indicators of systemic inflammation of peripheral blood and relative indicators: neutrophil‑lymphocytic and platelet‑lymphocytic ratio, the course of squamous cell carcinoma of the oral mucosa and gastric adenocarcinoma.Materials and methods. Prospective analysis of patients with squamous cell carcinoma of the oral mucosa and disseminated gastric adenocarcinoma was performed. Patients with verified diagnosis, without signs of inflammatory diseases in anamnesis, not receiving antibacterial and immunomodulatory therapy were selected. Overall survival and survival without progression were considered as the main estimated parameters.Results. The selection criteria were met by 32 patients with disseminated gastric adenocarcinoma and 60 patients with squamous cell carcinoma of the oral mucosa. The prognostic value of relative indicators is determined: overall survival of patients with gastric adenocarcinoma with a low value of the neutrophil‑lymphocytic index is significantly higher than that of the rest of the cohort of patients: 16 months vs. 8 and 7 months (95 % CI (confidence interval) from 12 to 23 months, p=0.0382). Overall survival of patients with low platelet‑lymphocytic index was also higher: 16 months vs. 8 months (95 % CI from 11 to 24 months, р=0,0026). Different relapse‑free survival was noted in the group of patients with squamous cell head and neck cancer: patients with low index value it is 7 months vs. 2 months (95 % CI from 5 to 9 months, p=0.0499).Conclusions. The results show the possibility of using immunological microenvironment of the tumor and indices, characterizing the systemic inflammation, for prognosis of gastric adenocarcinoma and squamous cell carcinoma of the oral mucosa.
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.
