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

purposeIn pancreatic surgery, a relation between surgical volume and postoperative mortality and overall survival (OS) has been recognized, with high-volume centers reporting significantly better survival rates. We aimed to explore the influence of hospital volume on administration of palliative chemotherapy and OS in the Netherlands.

methodsPatients diagnosed between 2007 and 2011 with metastatic pancreatic cancer were identified in the Netherlands Cancer Registry. Three types of high-volume centers were defined: high-volume (1) incidence center, based on the number of patients diagnosed with metastatic pancreatic cancer, (2) treatment center based on number of patients with metastatic pancreatic cancer who started treatment with palliative chemotherapy and (3) surgical center based on the number of resections with curative intent for pancreatic cancer. Independent predictors of administration of palliative chemotherapy were evaluated by means of logistic regression analysis. The multivariable Cox proportional hazard model was used to assess the impact of being diagnosed or treated in high-volume centers on survival.

resultsA total of 5385 patients presented with metastatic pancreatic cancer of which 24 % received palliative chemotherapy. Being treated with chemotherapy in a high-volume chemotherapy treatment center was associated with improved survival (HR 0.76, 95 % CI 0.67-0.87). Also, in all patients with metastatic pancreatic cancer, being diagnosed in a high-volume surgical center was associated with improved survival (HR 0.74, 95 % CI 0.66-0.83).

conclusionsHospital volume of palliative chemotherapy for metastatic pancreatic cancer was associated with improved survival, demonstrating that a volume-outcome relationship, as described for pancreatic surgery, may also exist for pancreatic medical oncology.
