Dynamic esophageal manometry reveals pseudoachalasia secondary to metastatic breast cancer: A case report.
Article in World journal of clinical oncology, 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
backgroundPseudoachalasia mimics primary achalasia in symptoms and diagnostic findings, as observed in gastroscopy and barium swallow studies. However, pseudoachalasia, often associated with malignancies like metastatic breast cancer, requires prompt differentiation to avoid misdiagnosis and inappropriate treatment. This report highlights a rare case of pseudoachalasia secondary to metastatic breast cancer and highlights the diagnostic value of esophageal motility changes. CASE SUMMARY: A 52-year-old woman presented with a one-year history of intermittent dysphagia following breast cancer surgery. Initial examinations suggested achalasia, but the patient's high-resolution manometry (HRM) results showed a rapid shift from ineffective esophageal motility to type II achalasia within four months. Further investigations revealed metastatic adenocarcinoma of the cardia, originating from the breast.
conclusionIn patients with a history of malignancy, rapidly evolving esophageal motility abnormalities should raise suspicion of pseudoachalasia. HRM plays a crucial role in differentiating between primary and secondary achalasia. Early diagnosis through advanced imaging and pathology is essential for proper management.
