Is there a role for second-line platinum re-challenge in advanced biliary tract cancers?

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
The clinical benefit of second-line chemotherapy in advanced biliary tract cancers is currently unknown. We investigated the role of platinum re-challenge in a selected cohort of patients who progressed after first-line gemcitabine/cisplatin (GemCis) chemotherapy. We retrospectively analysed seventy-four patients treated between January 2008 and September 2012 at Nottingham University Hospitals. Demographics, treatment data, radiological response and survival data were captured. Univariate and multivariate analysis of survival outcomes were evaluated. Platinum sensitive disease was defined as tumours that progress after 12 weeks of completion of first-line GemCis chemotherapy. Seventy-four patients (median age = 67 years) had received first-line chemotherapy (gemcitabine alone = 21/74, Gem/Cis combination = 53/74). Best response to GemCis chemotherapy was as follows; partial response (PR) (17 %), stabilisation of disease (SD) (39.6 %), disease control rate (DCR) (56.6 %) and disease progression (43.4 %). 18/74 patients received second-line chemotherapy [GemCis (12/18), 5-FU/cisplatin (4/18), gemcitabine (2/8)]. Best response to GemCis second-line chemotherapy was as follows: PR (33.3 %), SD (33.3 %) and DCR (66.6 %). The median overall survival in patients who received second-line chemotherapy was 29 months compared to 10.6 months in patients who received first-line therapy only (p = 0.00001). The data suggest that patients who progress after 12 weeks of completion of first-line therapy may remain platinum sensitive and benefit from second-line platinum re-challenge. Prospective multicentre studies are warranted to explore this possibility further.
