1 · What the graph read from it

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.

2 · The registry

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

Whether pancreatoduodenectomy or papillary resection should be performed to achieve curative treatment for neuroendocrine tumors of the minor duodenal papilla with a diameter of ≤2 cm is controversial. We report a 35-year-old male patient with a rare case of a neuroendocrine tumor of the minor duodenal papilla. The patient was referred to our hospital from a different clinic for dilatation of his minor duodenal papilla. Duodenoscopy revealed a smooth mass of 2 cm in diameter in the minor papilla, and the biopsy specimen was diagnosed as neuroendocrine tumor G1. The patient underwent subtotal stomach-preserving pancreatoduodenectomy. Histological evaluation showed a single nodule of 15 mm in diameter in the mucosa with metastasis to the regional lymph node. The tumor cells exhibited immunoactivity against synaptophysin and chromogranin A. The molecular immunology Borstel-1 index was less than 1%, and the grade was neuroendocrine tumor G1. We reviewed the characteristics of 24 cases of patients who underwent PD for NETs of the minor duodenal papilla in English literature. In 22 of these cases, the tumor depth was described. Lymph node metastasis was observed in none of the three cases (0%) in which the tumor was limited to the intra-sphincter; however, it was noted in three (30%) of the 10 cases in which the tumor had invaded the duodenal submucosa and in eight (89%) of the nine cases in which the tumor had invaded the muscularis propria, pancreas, peripancreatic/periduodenal tissues, or duodenal serosa. Making a definitive diagnosis preoperatively or intraoperatively whether the tumor invades beyond the sphincter or not and whether regional lymph node metastasis is present may not be possible. Therefore, we believe that pancreatoduodenectomy with lymphadenectomy is preferable for curative treatment of neuroendocrine tumors of the minor duodenal papilla.
