Treatment rechallenge is safe and leads to better survival in pancreatic cancer patients with interstitial pneumonitis.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
aimsInterstitial pneumonitis is a potentially fatal complication of cancer-related therapy. However, data regarding the risk factors, prognosis and safety and benefit of rechallenge treatment are scarce.
methodsPatients diagnosed with pancreatic cancer were retrospectively enrolled, and those with pneumonitis were identified. We investigated the incidence and etiology of pneumonitis, potential risk factors, and impact of treatment rechallenge on clinical outcomes.
resultsA total of 809 patients were diagnosed with pancreatic cancer, among whom 62 (7.7%) were diagnosed with interstitial pneumonitis. Risk factors identified through competing risk analysis included nab-paclitaxel, gemcitabine, erlotinib, and previous lung diseases such as pre-existing ILD, asthma, chronic obstructive pulmonary disease, tuberculosis, primary lung cancer, metastasis, or pneumonia. Among these patients, 33 experienced acute respiratory distress syndrome, resulting in 15 deaths during pneumonitis episodes. After rechallenge therapy in 33 patients, pneumonitis recurred in 3 (9%). The median overall survival was longer in patients with pneumonitis than in those without. Subgroup analysis further revealed that overall survival was significantly better in the rechallenge group.
conclusionsMost cases of pneumonitis are not directly induced by cancer therapy. Therefore, treatment rechallenge is considered a reasonable approach, potentially resulting in improved survival outcomes.
