Defying the Prognostic Odds: A Case Report of Unexpected Complete Remission of Metastatic Ampullary Carcinoma With Palliative Chemotherapy.
Article in Case reports in oncological medicine, 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
Metastatic ampullary carcinoma (AC) almost always carries a poor prognosis. We present a remarkable case of a 69-year-old male with Stage IV pancreaticobiliary-type AC who achieved a complete remission after 45 months of palliative modified FOLFIRINOX chemotherapy (5-fluorouracil, oxaliplatin, leucovorin, irinotecan). This unexpected outcome challenges the conventional understanding of the natural history of advanced AC. Furthermore, molecular analysis revealed a pathogenic PALB2 mutation, along with variants of unknown significance in the POLD1 and RAD50 genes, coding for enzymes involved in various deoxyribonucleic acid (DNA) repair pathways. These findings raise questions about their potential influence on treatment response and prognosis. This case underscores the need for further investigation into the role of molecular alterations and personalized approaches in managing advanced AC.
