Application of Rose and Wright's algorithm in the diagnosis of lacrimal gland masses: a study of 93 cases.

OBJECTIVE

To investigate the application of Rose and Wright's algorithm in diagnosing lacrimal gland masses.

DESIGN

Retrospective observational cases series.

PARTICIPANTS

A total of 93 consecutive patients with primary masses within the orbital lobe of the lacrimal gland were reviewed.

METHODS

Before treatment, patients' detailed history was collected verbally and all patients underwent image examination (computed tomography and magnetic resonance imaging). The clinical and radiological features of every patient were evaluated by experienced orbital surgeons. Based on Rose and Wright's criteria, patients were scored and then treated using surgery with radiotherapy and/or chemotherapy. The final diagnoses were based on the histopathologic results. Based on the histopathologic diagnosis, the data from Rose and Wright's algorithm were evaluated.

RESULTS

The accuracy of Rose and Wright's algorithm for benign and malignant tumour diagnoses was 75% and 50%, respectively. The diagnostic sensitivity, specificity, and accuracy of Rose and Wright's algorithm were 64%, 93%, and 86%, respectively. The algorithm demonstrated significant accuracy in the clinicoradiological criterion in differentiating between benign tumours and malignant tumours (p < 0.05).

CONCLUSIONS

Rose and Wright's algorithm has great advantages in distinguishing benign from malignant tumours within the orbital lobe of the lacrimal gland. However, the algorithm should be used with great caution because of its low diagnostic sensitivity for malignant tumours.
