Abstract:
Objective To study the clinical features, diagnosis and treatment of multiple primary cancer of digestive tract (MPCDT). Methods The clinical data of 33 cases of MPCDT were analysed retrospectively. Results The incidence of MPCDT was 2.7% in all patients with primary cancer of digestive tract. 24 cases was synchronous carcinoma (SC), of whom, 20 was misdignosis. All the cases of SC received comprehensive treatment, including radical resection, traditional medicine and radiotherapy respectively. 9 cases were metachronous carcinoma (MC), of them, only 1 case misdiagnosed. All the MC cases received radical resection, palliative resection and radiotherapy. The 5-year survival rate in cases of MPCDT, SC and MC were 45.4%, 37.5% and 55.5% respectively. Conclusions The incidence of MPCDT is low, but misdiagnosis rate is hight. For MPCDT, comprehensive treatment, and radical resection and re-operation should be done. It is advisable not to diagnose MC as recurrence or metastasis.
