Neoadjuvant chemotherapy with gemcitabine-based regimens improves the prognosis of node positive resectable pancreatic head cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The effectiveness of preoperative (neoadjuvant) chemotherapy (NAC) for resectable pancreatic ductal adenocarcinoma (PDAC) remains unclear. The present study retrospectively evaluated the efficacy of NAC with gemcitabine (GEM)-based regimens or GEM monotherapy for resectable PDAC. Between 2006 and 2015, NAC with GEM was performed in 52 cases (head 31, and body and tail 21) and compared with 34 resection-only cases serving as controls (head 20, and body and tail 14). According to the Response Evaluation Criteria In Solid Tumors guidelines, the treatment effect was a partial response in 5 cases, stable disease in 45 cases, and progressive disease in 2 cases. Maximum standardized uptake values and carbohydrate antigen (CA19-9) values were significantly reduced after preoperative chemotherapy. Using the Evans grading system, the treatment effect was grade I in 31 patients, grade IIa in 8, and grade IIb in 3 cases. There were significant differences in the overall survival rate between the NAC and control groups, only in the patients with node-positive pancreatic head cancer. Significantly higher CA19-9 values in peripheral blood and higher lymph node metastasis and plexus invasion rates were observed in early-recurring cases within a year. The preoperative CA 19-9 cutoff value as an early recurrence risk factor was calculated as 30 U/ml in the NAC group and 88 U/ml in the control group. NAC with GEM prolonged survival in patients with node-positive pancreatic head cancer. High CA19-9 values before operation, lymph node metastases and plexus invasion were risk factors for early tumor recurrence after surgery. Preoperative chemotherapy would be necessary for resectable pancreatic head cancer as lymph node metastasis was observed in >60% with resectable PDAC. Moreover, if normalization of CA19-9 values is not achieved with NAC, extension of preoperative chemotherapy should be considered as for borderline resectable PDAC cases.
