The aim of this study was to evaluate serial determinations of CYFRA 21-l in the follow-up of patients treated surgically for non- small cell lung cancer in order to predict the risk of turnour recurrence. SerumIevelsofCYFRA21-1 weremeasurcdusinganimmunoradiometric assay (CIS bio) in 57 patients with operable non-small cell lung cancer (NSCLC): 2.5 with squamous cell carcinoma (SqCC), 20 with adenocarcinoma (AC), 12 with large cell carcinoma (LCC).and 30 with nonmalignant lung diseases. Elevated preoperative CYFRA21-1 levels were identified in 44% of all patients with NSCLC. The diagnostic specificity of the assay was 97%. Positive CYFRA 21-1 levels was observed in 30% of stage I, 33% of stage II, and 55% of stage IIIa. Statistically significant differences were obtained between stages I and IIIa, II and IIIa, but not between stages I and II. During follow-up recurrence wasobserved in 19 of 57 (33 46) NSCLC patients. Recurrence- free survival probability for patients with elevated serum CYFRA 21- 1 levels before surgery was 52% (13/25), versus 81% (26/32) for patients with normal serum CYFRA 21-l levels (p < 0.01). In 15 patients with increased trend forCYFRA21-1, elevatedserum CYFRA 21-I levels preceded (13 patients) or coincided (2 patients) with the clinical detection of tumour recurrence, providing a predictive value of an increased trend of 87 96. In the multivariate analysis the association of the increase of CYFRA 21-1 level with a higher risk of recurrence is statistically significant (p < 0.001). Our results indicate that serial determination of CYFRA 21-1 may be of value in assessing the efficacy to surgical treatment of patients with NSCLC.

Background - The incidence of metastases to mediastinal lymph nodes was evaluated in patients with normal sized mediastinal nodes on thecomputed tomographic (CT) scan who underwent thoracotomy. The useof hilar lymph nodes in predicting mediastinal lymph node metastases was also assessed. Methods - Ninety patients with non-small cell lung cancer who later underwent thoracotomy were prospectively examined by CT scanning. Lymph nodes with a short axis diameter of 10 mm or more were considered abnormal. Results - Mediastinal lymph node metastases werepresent at thoracotomyin 19patients (21%). In 14 these Iymph node metastases were misdiagnosed because the nodes were normal in size on the CT scan. In only one of the 19 patients with N2 nodes was an N 1 lymph node enlarged, and four of the 19 patients with N2 nodes had metastases to these mediastinal nodes without Nl disease (‘skipping metastaaes’). Conclusionr - Metastases in normal sized nodes seen on the CT scan are a major problem in staging.
