Abstract:
Objective:To study the clinicopathologic features of lymphoproliferative disease by lymph node core needle biopsy(CNB)and to evaluate the diagnostic significance of CNB for lymphoproliferative disease.
Methods:The annual distribution, entity constitute, clinical finding, gross feature, morphologic change, affiliate study and repeat biopsy diagnosis of 1 013 cases of lymph node CNB diagnosed at West China Hospital of Sichuan University from January 2009 to December 2015 were investigated.
Results:(1) Proportion of lymph node CNB in total amount of biopsy specimens increased from 0.2% in 2009 to 0.8% in 2015.(2) The study cohort included 471 lymphomas, 12 atypical lymphoid hyperplasia (ALH), 136 suspected lymphomas, 372 benign lesions, and 22 cases of descriptive diagnoses. The most common types were diffuse large B cell lymphoma and T-lymphoblastic lymphoma. (3) Majority of patients were adolescents and children younger than 20 years or the elderly older than 60 years. 53.1% CNB tumor specimen consisted of ≥4 tissue cores and 40.5% were >2 cm in length. (4) 104 CNB cases with previous history of excision biopsy was included 45 carcinomas(no metastatic carcinoma was found), 32 lymphomas for treatment observation.1/14 suspicious lymphomas, 1/1 ALH and 3/22 cases benign lesions were diagnosed as lymphoma by repeat biopsy respectively. (5) 217 CNB cases were diagnosed as lymphoma by subsequent CNB (70), or subsequent excision biopsy (147) including 78.5%(73/93) suspected lymphomas, 5/7 ALH and 32.3%(20/62)benign lesions.
Conclusions:Lymph node CNB has certain clinical indications, although limited for the diagnosis of lymphoproliferative disorders. Suspected lymphomas and ALH diagnosed by CNB should be followed by repeat tissue biopsy. For the benign lesions by CNB it does not rule out additional biopsy to further investigate the lesion.
