About this trial
This is a pragmatic clinical trial that will study the effect of a radiomics-based computer-aided diagnosis (CAD) tool on clinicians' management of pulmonary nodules (PNs) compared to usual care. Adults aged 35-89 years with 8-30mm PNs evaluated at Penn Medicine PN clinics will undergo 1:1 randomization to one of two groups, defined by the PN malignancy risk stratification strategy used by evaluating clinicians: 1) usual care or 2) usual care + use of a radiomics-based CAD tool.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Male or female, aged 35-89 years
Scheduled to be evaluated at a UPHS PN clinic
Newly discovered solid or part-solid indeterminate PN 8-30mm in maximal diameter on CT imaging within 60 days of index clinic visit
Chest CT imaging meeting the technical requirements for compatibility with Optellum Virtual Nodule Clinic software
Disqualifiers
Chest CT imaging with discrete mediastinal or hilar lymphadenopathy by CT size criteria (>10mm in maximal short-axis diameter on axial CT images)
PNs with popcorn calcification (consistent with benign etiology)
Pure ground-glass subsolid PNs (may be associated with lower risk of clinically significant malignancy)
PN previously seen on CT imaging >60 days prior to most recent CT

Treatments tested in this trial
Optellum Virtual Nodule Clinic
DeviceThe Optellum Virtual Nodule Clinic is an FDA-approved (Class II) device for risk stratification of pulmonary nodules. It uses a convolutional neural network to evaluate CT imaging data to provide an estimate of malignancy risk for indeterminate pulmonary nodules.
Treatment groups
Trial outcomes
Primary outcomes
Appropriate management of pulmonary nodule
The composite proportion of benign pulmonary nodules managed with imaging surveillance and malignant pulmonary nodules managed with biopsy or empiric treatment. Final pulmonary nodule diagnosis will be categorized as malignant or benign based on pathologic evaluation. If pathology is unavailable or inconclusive (i.e., the biopsy was non-diagnostic), pulmonary nodule resolution, shrinkage, or diameter stability at 12 months will be defined as a benign diagnosis.
Secondary outcomes
Timeliness of care
For patients with malignant pulmonary nodules, defined as the number of days between the index clinic visit and diagnosis of malignancy and receipt of treatment for malignancy (i.e., surgical resection, radiation therapy).
Adverse events
For patients undergoing biopsy, defined as procedural complications related to pulmonary nodule biopsy.
Diagnostic yield
Using information found in pathology reports, defined as the proportion of biopsies with a definitive histopathologic diagnosis, for each type of diagnostic biopsy procedure.
Healthcare costs
The costs of all imaging studies and diagnostic testing associated with the pulmonary nodule diagnostic process, based on Medicare allowed amounts (amount paid by Medicare and the amount paid by the beneficiary and/or third parties).
