Diagnostic biopsy of lymph nodes of the neck, axilla and groin: rhyme, reason or chance?

Abstract

Introduction: Improving patient pathways of care is becoming increasingly important in the delivery of timely, appropriate surgical care. With this aim, we analysed the referral and management pathway of patients undergoing diagnostic superficial lymph node biopsy.

Patients and methods: A retrospective review of case notes of patients undergoing diagnostic superficial lymph node biopsy over 3 years, 1998-2000 at the Bradford Hospitals NHS Trust. Indication for surgical biopsy was based on clinical suspicion following assessment in the out-patient clinic for the majority, and arrangement of investigations as deemed appropriate. There were no clinical algorithms in use during the study period.

Results: There was no evidence for the use of explicit protocols for referral or management. Biopsy was often delayed. Of 268 patients referred from primary care, referral was made to any of 14 hospital Department with 39% (105 of 268) attending more than one outpatient appointment, and 155 (41 of 268) attending more than one department. Eighteen percent (47 of 268) of patients were informed of their diagnosis within 6 weeks of referral and 42% (113 of 268) within 3 months of referral. Nine percent (24 of 268) underwent pre-operative fine needle aspiration cytology. Of patients with enlarged neck nodes, 29% (52/180) had examination of the upper aero-digestive tract.

Conclusions: The study supports the introduction of co-ordinated problem-based referral and management pathways for the management of patients with enlarged superficial lymph nodes supported by regular audits of practice.
