[Clinical features of mucosa-associated lymphoid tissue lymphoma in head and neck].

Objective:To summarize the clinical features, diagnosis and treatment of mucosa-associated lymphoid tissue(MALT) lymphoma in head and neck. Method:The clinical data of 22 hospitalizedpatients with MALT lymphoma in head and neck during the recent 18 years were analyzed retrospectively. Result: Among the 22 cases, 13 patients showed salivary gland lesions, 4 showed larynx and trachea lesions,3 showed nasopharynx lesions and 2 showed thyroid gland lesions. The clinical manifestation was occupying or compression. Among them,12 patients received chemotherapy or chemoradiotherapy,5 received surgery plus chemotherapy,3 received surgery plus radiotherapy, 1 received surgery alone and 1 received radiotherapy alone; complete response(CR) occurred in 15 patients, partial response(PR) occurred in 6 patients, and 1 was stable disease(SD). The mean follow-up time was 92(8-211) months. During the follow-up period, 18 patients survived, 4 died, the three year progression free survival(PFS) and overall survival(OS) were both 95.2%, and the fiveyear PFS and OS were 79.4% and 89.6% respectively. Conclusion:The prognosis of MALT lymphoma in head and neck was good. MALT lymphoma has no specific clinical manifestations. Chemotherapy was the main treatment. Local treatment can be conducted for patients with localized lesions. .
