摘要: The main curative therapy for patients with nonsmall cell lung cancer is surgery. Despite this, the survival rate only 50%, therefore it important to more efficiently diagnose and predict prognosis patients. Raman spectroscopy useful in diagnosis of malignant premalignant lesions. aim this study investigate ability microscopy from surgically resected tissue sections, these Tumor sections resections are mapped by spectra analzsed using multivariate techniques. Spectra tumor samples also compared their outcome data define prognostic significance. Using principal component analysis random forest classification, differentiates normal tissue. Principal 34 predicts early postoperative recurrence a sensitivity 73% specificity 74%. Spectral reveals elevated porphyrin levels DNA samples. can be technique receiving surgery, elucidating biochemical properties tumors.
