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

A 69-year-old man was clinically diagnosed as stage IV gastric cancer with peritoneal dissemination. We performed systemic chemotherapy consisting of S-1 plus oxaliplatin as a first line, and ramucirumab plus nab-paclitaxel as a second line. However, CT and EGD revealed growth of the primary tumor and the lymph nodes along the lesser curvature and adjacent to the cardia. In addition, CT revealed ascites in the rectovesical pouch. Therefore, treatment was switched to nivolumab. After 3 treatment courses, CT revealed shrinkage of lymph nodes and disappearance of ascites. After 12 courses of nivolumab, however, EGD revealed growth of the tumors in the stomach with minor hemorrhage, prompting the consideration of gastrectomy. At the time of laparotomy, the peritoneal dissemination had completely disappeared, and peritoneal cytology was negative. Therefore, total gastrectomy with D2 and paraaortic lymphadenectomy was performed, after 21 months following the initial diagnosis. To our knowledge, there are no previous reports that have demonstrated the disappearance of peritoneal dissemination and ascites in response to nivolumab, resulting in curative gastrectomy.
