Patient: Description of condition (onset time, main symptoms, hospital visited, etc.): My mother is 63 years old and has a tumor under her chin, which is now surgically removed and analyzed as adenoidal cystic carcinoma. Now the doctor says he recommends another surgery to enlarge the area, because he doesn’t want to operate again because he considers the old person is not in good health at an old age. What should the expert do? Thank you! Zhang Shurong, Cancer Center of Beijing Tongren Hospital: Adenoid cystic carcinoma is a special malignant tumor, which grows slowly but has strong local invasiveness and pro-neurological growth characteristics, lymphatic metastasis is rare but hematogenous metastasis is common, mainly to lung, bone, liver and brain. Surgery is the main effective treatment, relatively insensitive to radiotherapy and chemotherapy, the first surgical treatment is very critical and has a great impact on the prognosis.
