Comparison of in vivo probe-based confocal laser endomicroscopy with histopathology in lung cancer: A move toward optical biopsy.

Background And Objective: The development of novel technologies has increased the yield from transbronchial biopsies while preserving patient safety by guiding biopsies to the area of interest. Other technologies have helped identify pre-cancerous or sessile lesions in the endobronchial space by utilizing interactions between tissue and light at varying wavelengths. Probe-based confocal laser endomicroscopy (pCLE) is a new technology that encompasses the benefits of both guided biopsies and novel optical imaging in one device.

Response to spray cryotherapy in a patient with adenocarcinoma in the parietal pleura.

Malignancies of the parietal pleura, whether primary or metastatic, are a therapeutic challenge, and current therapies target their symptoms and not their tumor burden. Therefore, alternatives to standard approaches seem warranted. A patient with a parietal pleura-based adenocarcinoma was treated with low-pressure spray cryotherapy after failing more traditional approaches.
