Background: Patients with squamous cell carcinoma of the head and neck constitute a high risk group for synchronous and metachronous tumours.Objective: This study aimed to investigate the usefulness of white light and autofluorescence bronchoscopy in the evaluation of pre-malignant and early neoplastic lesions in patients with laryngeal cancer, who are at high risk of concomitant lung cancer.Methods: This prospective, cross-sectional study included 30 patients who had undergone total laryngectomy for squamous cell carcinoma of the larynx. The tracheobronchial system was investigated for the presence of pre-malignant and malignant lesions, using a combination of white light and autofluorescence bronchoscopy. Biopsies were obtained from areas with a pathological appearance, and histopathological studies were performed.Results: All patients had a permanent tracheostomy. Light and autofluorescence bronchoscopy indicated that the tracheobronchial system was normal in 11 patients. A total of 27 biopsies was taken from the remaining 19 patients, and revealed invasive squamous cell carcinoma in one patient and pre-malignant changes in six.Conclusion: Bronchoscopy is a valuable and practical tool for screening patients at high risk of lung cancer, and requires minimal intervention especially in patients with a permanent tracheostomy. Of the various bronchoscopic techniques becoming available, autofluorescence bronchoscopy shows promise for the detection of pre-invasive malignant changes of the tracheobronchial system in patients previously operated upon for laryngeal cancer.

Background: Non-small cell lung cancer (NSCLC) accounts for approximately 80% of new diagnoses of pulmonary carcinoma. This study investigated the correlation between 18 F-fluorodeoxyglucose uptake in computerized tomography integrated positron emission tomography and tumor size, lymph node metastasis, and distant metastasis in patients with NSCLC. Methods: The records of 151 NSCLC patients (139 male, 12 female; mean age 59.60 years) were evaluated retrospectively. Results: Forty-one cases were adenocarcinomas; 45 squamous cell carcinomas; and 65 unspecified NSCLC. When the cases were categorized according to tumor size (group 1, ≤ 3 cm; group 2, > 3 and≤5 cm; group 3, > 5 cm), the maximum standardized uptake value (SUVmax) was significantly lower in groups 1 and 2 compared with group 3 (p = 0.006 for each). Considering all cases, tumor SUVmax was not correlated with age, gender, or histopathological type. Lymph node metastases were pathologically proven in 24 cases: 24% of these were adenocarcinomas, 6% squamous cell carcinomas, and 16% unspecified NSCLC. Neither lymph node involvement nor distant metastases were correlated with tumor SUVmax, although lymph node size was positively correlated with lymph node SUVmax (r = 0.775; p>< 0.001). Conclusions: SUVmax was significantly associated with tumor size, but not with distant metastases or lymph node involvement. Therefore, SUVmax on positron emission tomography is not predictive of the presence of metastases. © 2013 Özgül et al.
