Summary
Superficial esophageal carcinoma with basaloid features (BE) shows a better prognosis than squamous cell carcinoma (SCC). BE carcinoma has a lower risk of nodal metastasis and improved survival rates, warranting distinct clinicopathological consideration.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Esophageal carcinoma presents a significant health challenge.
- Superficial esophageal carcinoma, limited to mucosa or submucosa, requires precise classification for prognostic accuracy.
Purpose of the Study:
- To investigate the clinicopathological features and prognostic implications of different histological types of superficial esophageal carcinoma.
- To determine if basaloid features (BE) in superficial esophageal carcinoma are associated with a better prognosis compared to conventional squamous cell carcinoma (SCC).
Main Methods:
- Retrospective review of 200 surgically resected esophageal carcinomas.
- Identification and classification of 50 superficial esophageal carcinomas into SCC, BE, mixed, and other types.
- Analysis of clinicopathological parameters including invasion depth, tumor size, histological type, nodal metastasis, and survival rates.
Main Results:
- Superficial esophageal carcinoma with basaloid features (BE) demonstrated a statistically significant difference in maximum longitudinal diameter compared to mixed types.
- None of the BE superficial carcinomas showed nodal metastasis, contrasting with 12.0% in SCC and 62.5% in mixed types.
- Cumulative survival rates were significantly better for BE superficial carcinoma than for mixed types.
Conclusions:
- The basaloid feature (BE) type of superficial esophageal carcinoma exhibits a better prognosis.
- BE superficial esophageal carcinoma should be distinguished from ordinary SCC with infiltrative growth due to significant clinicopathological and prognostic differences.
