85 Background: Adjuvant chemotherapy with gemcitabine (GEM) is standard care for resected pancreatic ductal adenocarcinoma (PDAC). Nab-paclitaxel plus gemcitabine (AG) vs gemcitabine (GEM) have shown better survival and tumor response with in advanced or metastatic PDAC. We aimed to determine the efficacy and safety of AG compared with GEM for resected PDAC. Methods: We retrospectively reviewed resectable PDAC patients (pts) who received AG or GEM as adjuvant chemotherapy from January 2013 to December 2016 at the Chinese PLA General Hospital, Bei Jing, China. Pts received nab-paclitaxel (125mg/m2) followed by GEM (1,000 mg/m2) on days 1, 8 every 3 weeks or GEM (1,000 mg/m2) alone on days 1, 8 every 3 weeks for 6 cycles unless disease progression or there was unacceptable level of adverse events. Disease free survival (DFS), overall survival (OS) and toxicity were analyzed. Results: Among 70 pts received AG or GEM as adjuvant chemotherapy, 10 pts were excluded due to the serious complication or R2 resection. The analysis was based on 30 pts in each group undergone complete macroscopic (R0 or R1) resection. Median DFS was 15.8 months (95% CI 13.1-18.5) in AG group (6 pts not arrived) compared with 12.2 months in GEM group (95% CI 9.6-14.8, P = 0.039, 3 pts not arrived). Median OS was 28.3 months (95% CI 21.9-34.6) in AG group (11 pts not arrived) as compared with 20.6 months in GEM group (95% CI 11.2-29.9, P= 0.028, 7 pts not arrived). The 2 years survival rate was 63.3% versus 43.3% in AG group versus GEM group. The most common adverse events of grade 3 or higher were leukopenia (32.3% in AG group vs. 20.7% in GEM group, P= 0.387), neutropenia (45.2% vs.31%, P= 0.298), G-CSF use (41.9% vs. 24.1%, P= 0.177), sensory peripheral neuropathy (51.6% vs. 24.1%, P= 0.036) and fatigue (3.2% vs. 3.4%, P= 0.737). Conclusions: Our results provide the evidence that the adjuvant combination of nab-paclitaxel plus gemcitabine significantly improved DFS and OS of resected PDAC.

Conclusions: Our results provide the first evidence that the adjuvant combination of nab-paclitaxel plus gemcitabine significantly improved DFS and OS of resected PDAC. Future RCTs with multi-center participation, particularly focused on adjuvant AG, can further provide information to confirm and strengthen these data.

Aim. To establish the association between pancreatic cancer precursor lesions and chronic opisthorchiasis. Materials and methods. A single center case-control study was conducted at a low-volume pancreatic surgery center in Khanty-Mansiysk. We retrospectively collected morphological data from 47 pancreatoduodenectomies performed for pancreatic ductal adenocarcinoma. The study group included 23 cases of pancreatic ductal adenocarcinoma with concomitant chronic Opisthorchis felineus invasion which were compared to 24 controls consisting of “pure” cancer. Qualitative analysis was performed using χ2 Pearson criterion. Exact Fisher test was used for small samples. Time to progression and overall survival rates were calculated using Kaplan-Meier survival analysis. Data were collected and analyzed in Statistica 7.0. Results. PanINs were seen in 41,7% pancreata resected for ductal adenocarcinoma of the head and in 95,7% cases of pancreatic cancer in background of chronic opisthorchiasis (р = 0,000; 95% CI 3,5-268). PanIN high grade were observed only in opisthorchiasis group. In mixed pathology invasive cancer component tended to be more dedifferentiated and advanced when compared to pure cancer group (p = 0,029). Median disease free survival was 9 mo. in both groups and overall survival was 13 mo. in non-opisthorchiasis group and 15,3 mo. in opisthorchiasis group (р = 0,437). Conclusion. Chronic opisthorchiasis is associated with pancreatic intraepithelial neoplasia. Pancreatic ductal adenocarcinoma in background of opisthorchiasis with preneoplastic lesions tend to be more advanced in stage and poorly differentiated. Disease free and overall survival have no statistically significant differences in patients with and without Opisthorchis felineus invasion.

Background: This study aims to identify the prognostic factors in Stage IIIA non-small cell lung cancer and to investigate whether there was a significant difference in terms of overall survival and disease-free survival among the subgroups belonging to this disease stage. Methods: Between January 2010 and December 2018, a total of 144 patients (125 males, 19 females; median age 60 years; range, 41 to 80 years) who were operated for non-small cell lung cancer in our clinic and whose pathological stage was reported as IIIA were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, histopathological diagnosis, the standardized uptake value of the mass on positron emission tomography-computed tomography, tumor diameter, type of surgery, lymph node metastasis status, visceral pleural invasion, and overall and disease-free survival rates were recorded. Results: The median survival was 39 (range, 27.8 to 46.1) months and the five-year overall survival rate was 28%. The mean tumor diameter was 4.3±2.7 cm. The median disease-free survival was 37 (range, 28.1 to 48.6) months and the five-year disease-free survival rate was 26.9%. In the multivariate analysis, overall survival and disease-free survival in T2N2M0 subgroup were significantly worse than the other subgroups. The other poor prognostic factors of survival were the standardized uptake value of the tumor, pneumonectomy, and histopathological subtypes other than squamous cell carcinoma and adenocarcinoma. Parietal pleural invasion was significantly associated with worse disease-free survival rates. Conclusion: Our results showed that there may be significant survival differences between subgroups created by tumor histopathology, lymph node invasion and the type of surgery in a heterogeneous lung cancer stage.
