There are few reports about the prognosis of patients or the course of the disease after surgery.OBJECTIVES: To clarify the clinical course of the disease after surgery and factors influencing the prognosis.METHODS: We retrospectively assessed 27 patients receiving surgery for small cell carcinoma (22 cases) and large neuroendocrine carcinoma (5 cases) from January 2005 through January 2015 at our hospital.RESULTS: Patients were all male, with an average age of 70.9 years. Of the 27 patients, 22 had received postoperative adjuvant chemotherapy. Median progression-free survival (PFS) and overall survival (OS) were 1.1 and 5.5 years, respectively. Ten patients were recurrence-free. Ten patients who underwent surgery within 60 days after the diagnosis demonstrated a better prognosis regarding OS (p<0.01) than those operated on after 60 days. The size of the tumor, titer of tumor markers, chemotherapy, smoking history, and age did not influence PFS or OS.CONCLUSIONS: Early surgical resection for high-grade neuroendocrine carcinoma stage I may lead to a better prgonosis.
