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

backgroundPancreatic ductal adenocarcinoma (PDAC) is among the most aggressive malignancies. The prognosis for recurrence after surgery is extremely unfavorable, and liver metastasis of PDAC confers poor prognosis despite resection. CASE PRESENTATION: A 69-year-old man was admitted to our hospital for further examination and treatment, including surgery for a pancreatic tumor. On close inspection, he was suspected to have pancreatic head cancer without enlarged lymph nodes or distant metastasis, and pancreatoduodenectomy with D2 lymph node dissection was performed. A postoperative pathological examination revealed well-differentiated invasive ductal adenocarcinoma with lymph node metastasis (stage IIB; pT2N1M0). Postoperatively, he received adjuvant chemotherapy containing gemcitabine for 1 year. Eight years after the radical surgery, his serum carbohydrate antigen 19-9 level was elevated, and computed tomography (CT) and magnetic resonance imaging revealed a well-circumscribed 10-mm mass in liver segment 5. Positron emission tomography/CT also revealed high fluorine-18-fluorodeoxyglucose uptake only in this hepatic tumor. Accordingly, the patient was diagnosed with a solitary liver metastasis of PDAC. As the liver metastasis was isolated and identified long after the initial surgery, we decided to resect it using laparoscopic partial hepatectomy of segment 5. Histopathological examination confirmed liver metastasis of PDAC and the patient received adjuvant chemotherapy containing S-1. No evidence of recurrence has been seen for 11 years since the pancreatoduodenectomy and 3 years since the hepatic resection.

conclusionsCases of metachronous liver metastasis of PDAC after radical surgery, in which patients exhibit long-term survival without recurrence after hepatectomy, are extremely rare. Hepatectomy may confer long-term survival, and the time to postoperative recurrence and the number of liver metastases may be useful criteria for deciding whether to perform hepatic resection.
