Incidental findings on single-photon emission computed tomography/computed tomography (SPECT/CT) lymphoscintigraphy in breast cancer: the proposed Westmead SPECT/CT incidental findings classification.
Article in ANZ journal of surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe aim of this study is to determine the prevalence of incidental radiological findings detected on SPECT/CT performed as part of pre-operative lymphoscintigraphy for sentinel lymph node biopsy (SLNB) in patients undergoing breast cancer surgery and development of a modified classification to workup these lesions.
methodsA retrospective audit was performed of all SPECT/CT performed in combination with lymphoscintigrams in breast cancer patients presenting with clinically node negative axillae and operated on by breast surgeons at the Westmead Breast Cancer Institute over a 12-month period.
resultsFour hundred and nineteen patients were included in the study. In 149 patients (35.6%), there was a total of 205 incidental findings. The most common findings were, pulmonary abnormalities (38.5%), abdominal findings (27.8%), thyroid nodules (14.6%), cardiac abnormalities (10.7%) and others (8.3%). Using our proposed Westmead SPECT/CT incidental findings (WSIF) classification, 7.8% were known, 17.6% were major findings, 48.3% were minor findings, 15.1% were minimal findings and 11.2% were equivocal findings. 17.6% (n = 36) underwent further workup and investigation and 3.4% of patients (n = 5) required therapeutic intervention, including chemotherapy for primary lung cancer(n = 1) and surgeries (thoracotomy, n = 1; thyroidectomy, n = 2; colonoscopy, n = 1). 93.8% (n = 393) had at least one SLN mapped, most commonly located in Level 1 of the axilla.
conclusionThe incidental findings on SPECT/CT in combination with lymphoscintigraphy is within the range of previous studies (27.3-59.5%). A small proportion of patients required significant major interventions (3.4%). We propose that all incidental findings should be assessed according to our WSIF classification to aid in triaging need for further investigation and management.
