Abstract

Bronchoscopy plays a major role in the histological diagnosis of stage III lung cancer and the choice among bronchoscopic techniques may very according to the central or peripheral localization of the lesion. To obtain the histological diagnosis, percutaneous needle aspiration and bronchoscopic procedures are rather complementary. In staging of bronchogenic carcinoma, bronchoscopy may confirm neoplastic involvement of the main carina (T4), involvement within 2 cm of the main carina (T3) or involvement of mediastinal nodes (N2 or N3) by the use of transbronchial needle aspiration. Extension of lung cancer to intrathoracic lymph nodes is better assessed by mediastinoscopy. The use of thoracoscopy in staging has been increasing in particular in cases of concomitant pleural effusion.

Non-radical diagnostic biopsies do not negatively influence melanoma patient survival.

BACKGROUND: In fair-skinned Caucasian populations both the incidence and mortality rates of cutaneous melanoma have been increasing over the past decades. With adjuvant therapies still being under investigation, early detection is the only way to improve melanoma patient survival. The influence of incisional biopsies on melanoma patient survival has been discussed for many years. This study investigates both the influence of diagnostic biopsy type and the presence of residual tumor cells in the re-excision specimen on disease free and overall survival. METHODS: After (partial) removal of a pigmented skin lesion 471 patients were diagnosed with stage I/II melanoma and underwent re-excision and a sentinel node biopsy. All patients were followed prospectively, mean follow up >5 years. Patients were divided according to their diagnostic biopsy type (wide excision biopsy, narrow excision biopsy, excision biopsy with positive margins and incisional biopsy) and the presence of residual tumor cells in their re-excision specimen. Survival analysis was done using Cox's proportional hazard model adjusted for eight important confounders of melanoma patient survival. RESULTS: The diagnostic biopsy was wide in 279 patients, narrow in 109 patients, 52 patients underwent an excision biopsy with positive margins and 31 patients an incisional biopsy. In 41 patients residual tumor cells were present in the re-excision specimen. Both the diagnostic biopsy type and the presence of tumor cells in the re-excision specimen did not influence disease free and overall survival of melanoma patients. CONCLUSIONS: Non-radical diagnostic biopsies do not negatively influence melanoma patient survival.
