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

backgroundPatients with localized (that is non-metastatic) pancreatic ductal adenocarcinoma with an inadequate response or toxicity to first-line chemotherapy may benefit from chemotherapy switch. The aim was to explore the available data on the use and effect of chemotherapy switch, as reported in the literature.

methodsA systematic search was conducted in Embase, MEDLINE (Ovid), the Web of Science, Cochrane, and Google Scholar on 1 December 2023. The main outcomes were the proportion of patients who underwent chemotherapy switch and the carbohydrate antigen 19-9 response and resection, R0 resection, and ypN0 resection rates after chemotherapy switch. Data were pooled using a random-effects model.

resultsA total of five retrospective studies, representing 863 patients with localized pancreatic ductal adenocarcinoma, were included and 226 of the 863 patients underwent chemotherapy switch. In four studies, first-line chemotherapy consisted of 5-fluorouracil/leucovorin/irinotecan with oxaliplatin ('FOLFIRINOX') and patients were switched to gemcitabine with nab-paclitaxel. Reasons for chemotherapy switch included an inadequate biochemical, clinical, or radiological response, or toxicity. Three studies compared patients who underwent chemotherapy switch with patients who only received first-line chemotherapy and found that the proportion of patients who underwent chemotherapy switch was 20.5% (95% c.i. 10.5% to 36.3%). The pooled resection rate after chemotherapy switch was 42.0% (95% c.i. 16.6% to 72.5%). Two studies compared the chance of resection after chemotherapy switch versus first-line chemotherapy alone and found a risk ratio of 0.88 (95% c.i. 0.65 to 1.18). Two studies, with a combined total of 576 patients, found similar postoperative survival for patients who underwent chemotherapy switch and patients who only received first-line chemotherapy.

conclusionOne in five patients with localized pancreatic ductal adenocarcinoma underwent chemotherapy switch after an inadequate response or toxicity to first-line chemotherapy. The pooled resection rate after chemotherapy switch was 42% and similar in overall survival compared with first-line chemotherapy only. Three ongoing trials are investigating chemotherapy switch in patients with an inadequate radiological or carbohydrate antigen 19-9 response.
