Neoadjuvant chemoradiation therapy application in radical esophagectomy surgery: Safety and feasibility: A descriptive study in Vietnam.
Observational study in 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
Esophageal cancer (EC) ranks as the 7th most prevalent form of cancer and the 6th leading cause of cancer-related mortality globally. Neoadjuvant therapy, encompassing neoadjuvant chemotherapy or chemoradiotherapy, has shown promise in reducing the staging of EC and mitigating the risk of early systemic spread. This study seeks to assess the safety and viability of implementing neoadjuvant chemoradiotherapy (nCRT) in conjunction with radical esophagectomy surgery for Vietnamese patients diagnosed with locally advanced EC. Safety was evaluated based on the incidence of grade ≥3 treatment-related adverse events, while feasibility was assessed through indicators such as pathological complete response, major pathological response, and R0 resection rates. The study analyzed data from 30 patients, following specific inclusion criteria. Baseline characteristics analysis revealed a participant cohort entirely composed of males, wherein 83.3% were identified as smokers, with tumors predominantly located in the middle (46.7%) and lower (53.3%) regions of the thoracic esophagus. The predominance of clinical stages II and III was observed. The nCRT protocol resulted in a substantial reduction in dysphagia score, with a statistically significant P < .001. The median duration from the conclusion of radiation treatment to surgery was 62 days, with a median operative time of 302 minutes and a median estimated blood loss of 189 mL. Surgical complications primarily included anastomotic leakage and pneumonia, occurring in 23.3% and 16.7% of cases, respectively. R0 resection was achieved in 29 (96.7%) patients, with 43.4% attaining pathological complete response and 56.7% demonstrating tumor complete response. The study's outcomes emphasize the safety and feasibility of employing esophagectomy subsequent to nCRT in Vietnamese patients, as evidenced by the absence of mortality, low complication rates, and favorable surgical results. It also suggests the potential advantages of utilizing a lower daily Gy dose for enhanced safety and considering squamous cell carcinoma as a specific criterion for nCRT.
