Upper abdominal computerized tomography scanning in staging non-small cell lung carcinoma

Area of Science:

• Oncology
• Radiology
• Surgical Oncology

Background:

• Accurate preoperative staging is crucial for non-small cell lung carcinoma (NSCLC) treatment planning.
• Adrenal gland metastases can significantly alter treatment strategies, potentially precluding curative surgery.
• Computed tomographic (CT) scanning is a standard imaging modality for cancer staging.

Purpose of the Study:

• To evaluate the utility of upper abdominal computed tomographic (CT) scanning in detecting occult adrenal metastases in patients with non-small cell lung carcinoma (NSCLC).
• To assess the impact of CT findings on surgical candidacy and treatment decisions.

Main Methods:

• Upper abdominal computed tomographic (CT) scanning was performed in 38 patients diagnosed with NSCLC.
• Patients with suspected adrenal metastases on CT underwent percutaneous fine-needle aspiration cytology.
• Treatment decisions, including thoracotomy, were based on staging and cytology results.

Main Results:

• Five out of 38 patients (13%) demonstrated suspected adrenal metastases on upper abdominal CT.
• Percutaneous fine-needle aspiration cytology confirmed metastatic carcinoma in both patients who underwent the procedure.
• These two patients, initially considered surgical candidates, were deemed ineligible for thoracotomy due to confirmed adrenal metastases.

Conclusions:

• Upper abdominal CT scanning is a valuable tool for identifying occult adrenal metastases in selected NSCLC patients.
• CT-detected adrenal metastases can significantly impact preoperative staging and alter surgical management plans.
• This imaging technique may help optimize patient selection and avoid unnecessary invasive procedures like thoracotomy.
