OBJECTIVE To explore the clinical features and surgical treatment of tumors associated with Castleman's disease (CD). METHODS The clinical profiles of 19 patients with neck giant lymph node hyperplasia were analyzed retrospectively. There were 8 males and 11 females with a median age of 40 years old (range: 7 - 74). The tumor locations were neck (n = 12), neck & mediastinal cavity (n = 2), axillary fossa (n = 2), retroperitoneal area (n = 2) and abdominal cavity (n = 1). RESULTS Eighteen of them underwent surgical resection of tumor or lymph nodes. All were diagnosed as CD by pathological examinations. There were 16 localized CD (LCD) including hyaline vascular type (HV type, n = 11), mixed type (mix type, n = 4) and plasma cell type-Hodgkin's disease (n = 1). Among 3 multicentric CD (MCD), there were 2 case of plasma cell type (PC type) and 1 case of mixed type (mix type). Long-term survival was achieved in 19 cases among which 1 case of plasma cell type MCD survived for 5 years and underwent a second operation and postoperative chemotherapy of CVP (cyclophosphamide, vincristine & prednisone) regimen for 3 cycles due to recurrence in 2 years and 1 case of plasma cell type LCD-Hodgkin's disease survived for 15 months and underwent a second operation and postoperative chemotherapy of ABVD (adriamycin, bleomycin, vinblastine & dacarbazine)regimen for 6 cycles due to recurrence in 6 months. One case of plasma cell type MCD in abdominal cavity on chemotherapy of CHOP (cyclophosphamide, hydroxydaunorubicin, vincristine & prednisone) regimen for 6 cycles was discharged after a successful management of intestinal obstruction. CONCLUSIONS The major clinical symptom of CD is a gradually enlarging painless mass. Surgical resection of tumor remains the first-line treatment for localized CD and the prognosis is excellent. Multicentric and plasma cell type CDs are prone to recurrence and transformation to lymphoma. And their first-line therapeutic should encompass multi-modality regimens of surgery and adjuvant chemotherapy. However, the clinical prognosis is still poor.
