Summary

Primary esophageal small-cell carcinoma (PESC) is highly malignant with early metastasis and poor prognosis. Surgical indications depend on TNM staging, with non-surgical therapy for advanced stages.

Area of Science:

  • Oncology
  • Gastroenterology
  • Surgical Pathology

Context:

  • Primary esophageal small-cell carcinoma (PESC) is a rare and aggressive malignancy.
  • Understanding its clinical characteristics is crucial for effective treatment strategies.

Purpose:

  • To elucidate the clinical biocharacteristics of PESC.
  • To identify prognostic factors and guide surgical and therapeutic decisions.

Summary:

  • PESC exhibits high resectability (93.6%) with low morbidity (17%) and 30-day mortality (2.1%), similar to ESCC and PEAC.
  • TNM staging and lymph node metastasis significantly impact survival; tumor length, invasion depth, and operation type have minimal influence.
  • The 5-year survival rate for PESC (7.5%) is considerably lower than for ESCC and PEAC (P < 0.01), with metastasis and recurrence being primary causes of death. Adjuvant chemotherapy showed no survival benefit.

Impact:

  • PESC is characterized by early lymphatic and hematogenous spread, leading to a poorer prognosis compared to ESCC and PEAC.
  • Lymph node metastasis is identified as the key prognostic determinant.
  • Recommendations include surgical resection for Stages 0, I, and IIa PESC, and non-surgical combined therapy for Stages IIb, III, and IV.
