Laparoscopic biopsy and staging for locally advanced pancreatic cancer: experiences of 76 consecutive patients in a single institution.
Article in Langenbeck's archives of surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPathological diagnosis plays a critical role in the treatment of locally advanced pancreatic cancer (LAPC). However, the commonly used biopsy methods still have a number of shortcomings, such as a relatively low diagnostic accuracy and a high incidence of complications.
methodsA retrospective review was conducted to compare 76 patients with laparoscopic biopsy and staging and 11 patients with CT-guided pancreatic biopsy for LAPC between January 2017 and October 2020. Logistic regression with univariate and multivariate analyses was performed to identify preoperative predictors of occult metastasis.
resultsThe diagnostic accuracy of laparoscopic biopsy and staging for pancreatic cancer was 100%. Sixty-two patients were confirmed to have LAPC, 59 patients by pancreatic biopsy and three patients by regional lymph node biopsy. Fourteen patients were diagnosed with distant occult metastasis, three patients by liver biopsy and 11 patients by peritoneum biopsy. Nine patients with severe obstructive manifestations underwent a simultaneous bypass procedure. No postoperative hemorrhage, pancreatic fistula, intra-abdominal infection, or trocar site metastasis was observed. Laparoscopic biopsy and staging had a higher diagnostic accuracy (100% vs. 81.8%, p=0.0147) and a shorter duration to chemotherapy (3 days vs. 9 days, p=0.035) than CT-guided biopsy. Elevated CA125 levels (≥35 U/ml) were a significant preoperative predictor of occult metastasis (OR 6.482, 95% CI 1.624-25.874, p=0.008).
conclusionsLaparoscopic biopsy and staging are safe and effective methods to obtain rapid pathology and precise staging for LAPC patients, especially for patients with elevated CA125 levels.
