Daily practices in chemotherapy for advanced gastric or gastroesophageal junction adenocarcinoma: METESTOMAC French prospective cohort.
Article in Cancer medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAround 50% of gastric cancers are diagnosed at an advanced stage. Several chemotherapy regimens are now internationally validated. Few data are available on the routine daily management of advanced gastric or gastroesophageal junction cancers. We aimed to describe chemotherapy practices, tolerance, and efficacy overall survival (OS) and Progression free survival (PFS) in a prospective French cohort.
methodsPatients starting palliative chemotherapy were prospectively enrolled in 49 French centres. The primary objective was to report and describe patients' characteristics and treatment strategies. Secondary objectives were OS, PFS, objective response rate, adverse events rate, performance status deterioration during the chemotherapy.
resultsA total of 182 patients were included; 179 were analysed. Most patients received platinium-based chemotherapy as the first treatment and FOLFIRI as second; 62.0% of patients received a second line, and 32.4% a third line. More than two thirds of Her2-positive patients were first treated with trastuzumab. The FOLFIRI regimen was the most frequently used second-line therapy. Median OS was 13.3 months, similar whatever the chemotherapy or combinations used in the first line. One- and 2-year OS increased with the number of chemotherapy lines received, from respectively 24.7% and 5.7% (1 line), to 46.9% and 12.4% (2 lines) and 88.1% and 29.9% (3 or more lines) (p < 0.0001).
conclusionOur study showed that treatment strategies in France are based on a succession of doublets, making it possible to offer a second and third line of treatment more often. This treatment strategy must be taken into account for future trials with immunotherapy combinations.
