The impact of peritoneal lavage cytology in biliary tract cancer (KHBO1701): Kansai Hepato-Biliary Oncology Group.
Article in Cancer reports (Hoboken, N.J.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundOnly few studies in literature have analyzed the clinical effects of peritoneal lavage status in biliary tract cancers.
aimWe aimed to assess the effect of cytology-positive peritoneal lavage on survival for patients with biliary tract cancer who underwent curative resection.
methodsThe KHBO1701 study was a multi-institutional retrospective study that assessed the clinical effects of peritoneal lavage cytology in biliary tract cancers. Using clinicopathological data from 11 Japanese institutions, we compared long-term outcomes between patients with cytology-positive and cytology-negative peritoneal lavage.
resultsOf 169 patients who underwent curative resection, 164 were cytology-negative, and five were cytology-positive. The incidence of portal invasion and preoperative carbohydrate antigen 19-9 levels were higher in the cytology-positive group than in the cytology-negative group. The incidence of peritoneal metastatic recurrence was also higher, and overall survival tended to be worse in the cytology-positive group. In contrast, recurrence-free survival was similar between the cytology-negative and cytology-positive groups.
conclusionsThe positive status of peritoneal lavage cytology could moderately affect the survival of patients with biliary tract cancers. Given that surgical resection is the only curative treatment option, it may be acceptable to resect biliary tract cancers without other non-curative factors, regardless of peritoneal lavage cytology status.
