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

backgroundThe best management of patients who have unresectable mucinous appendiceal cancer (MAC) with peritoneal spread after a failed attempt at cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is unclear. This study aimed to assess outcomes after systemic chemotherapy (SCT) for patients with unresectable peritoneal metastases from high-grade MAC.

methodsA single-center retrospective cohort study was conducted using a prospective CRS/HIPEC database. The study included high-grade MAC patients with peritoneal carcinomatosis who were deemed surgical candidates, but had an aborted CRS/HIPEC or only palliative HIPEC due to unresectable disease. Overall survival (OS) was compared.

resultsOf 72 identified patients, 20 received SCT and 52 did not (NoCT). The groups were balanced by age (p = 0.299), sex (p = 0.930), histopathologic subtype (p = 0.096), preoperative chemotherapy (p = 0.981), and postoperative major complication rates (p = 0.338). Both groups had extensive disease (median peritoneal cancer index at exploration, 39 vs 39). The median number of cycles was 12 (interquartile range [IQR], 6-15), and the median time between the procedure and SCT was 7 weeks (IQR, 5-10 weeks). The median follow-up period was 65 months. The median OS was significantly higher for the SCT group (26 months; 95 % confidence interval [CI], 10.8-41.5 months) than for the NoCT group (12 months; 95 % CI, 9.6-14.4 months) (p < 0.001), with hazard ratio (HR) of 0.22 (95 % CI, 0.08-0.66; p = 0.007) after adjustment for other factors.

conclusionSystemic chemotherapy is associated with improved OS for high-grade MAC patients with unresectable peritoneal metastases who are deemed surgical candidates but underwent an unsuccessful CRS/HIPEC attempt. Further prospective studies with a larger sample are required to identify patient subgroups who benefit the most from SCT.
