ABSTRACT

Objective To study the clinical and pathological features of rectal carcinoid and factors influencing the prognosis.Methods Data of 33 rectal carcinoid patients were analyzed retrospectively. 29 patients were followed up postoperatively. Primary tumors were classified by size (2*!cm) and muscularis invasion respectively.Results The main symptoms were changes in bowel habits(17/33,52%) and hematochezia (14/33, 42%), or rectal mass (14/33,42%), asymptomatic patients were detected during a survey.Only 4(12%) patients had tumors larger than 2 cm and tumors invading muscularis.The 10 year survival rate was 84% for all patients( n =29), and 94% for those with tumors 2*!cm( n =3) died in 5 years( P = 1 0?10 -9 ) and only one out of the 4 with muscularis invasion lived longer than 5 years( P =1 2?10 -5 ).Conclusions Most rectum carcinoid are at early stage suitable for local excision.
