Chao YK, et al. - In this study, researchers sought to assess the factors that could affect the diagnostic accuracy of post-neoadjuvant chemoradiotherapy (nCRT) endoscopic biopsy in patients with esophageal squamous cell carcinoma (ESCC). they recognized a higher diagnostic accuracy of the endoscopic biopsies performed ≥45 days after nCRT. This time cutoff could serve as a reference to inform the choice of the optimal treatment strategy following nCRT. This was particularly noted among complete responders in whom surgery withholding was being considered.
