[Prevalence of malignancy in preoperatively undetermined solid round lesions]

|February 1, 1990
Summary
Solitary pulmonary nodules often require surgery for diagnosis when biopsies are inconclusive. This study shows 35% of these unclear nodules in patients over 50 are malignant, indicating surgery is often necessary.
Area of Science:
- Pulmonology
- Thoracic Surgery
- Oncology
Context:
- Solitary pulmonary nodules (SPNs) present a diagnostic challenge when preoperative biopsy is insufficient.
- Patients undergoing evaluation for SPNs are typically middle-aged or older.
Purpose:
- To evaluate the diagnostic yield and necessity of surgical intervention for solitary pulmonary nodules lacking preoperative diagnosis.
- To determine the malignancy rate of SPNs that are not amenable to diagnosis via biopsy.
Summary:
- Twenty patients (average age 53.9 years) with SPNs underwent surgery due to inconclusive preoperative biopsy results.
- Surgical exploration revealed that 35% of these indeterminate solitary lesions were malignant.
- Thoracotomy is indicated for surgical clarification in this patient group, assuming acceptable medical risk.
Impact:
- Highlights the significant rate of malignancy in diagnostically challenging SPNs.
- Supports the role of surgical intervention in the management of indeterminate SPNs in older adults.
- Informs clinical decision-making regarding the workup of solitary pulmonary nodules.
