Pulmonary large cell neuroendocrine carcinoma (lcnec) is a subtype of lung cancer with neuroendocrine morphology, neuroendocrine differentiation on immunohistochemistry, a high mitotic rate (>10 mitosis·2 mm −2) and nonsmall cell cytological features [].lcnec is rare and accounts for ∼3% of all lung cancers, but the proportion of lung.
Large cell neuroendocrine lung cancer. New molecular classification of large cell neuroendocrine carcinoma and small cell lung carcinoma with potential therapeutic impacts. I had surgery the end of october to remove the left upper lobe of my lung. Large cell neuroendocrine carcinomas of the lung display morphologic and immunohistochemical characteristics common to neuroendocrine tumors and the morphologic features of large cell carcinomas.
It is also classified as a pulmonary neuroendocrine tumor. Recently my dad was diagnoseed w stage 4 large cell neuroendocrine. Ln the lung, neuroendocrine cancer can arise from the carcinoid cells, or it can appear as small cell lung cancer (sclc) or large cell neuroendocrine carcinoma.
Large cell neuroendocrine carcinoma stage 4. Had surgury to remove part of the tumor in the brain but half of the tumor was around the brain stem. The large cell neuroendocrine carcinoma (lcnec) of the lung was first reported in detail by travis et al.
Due to the rarity of lcnec, there are no large randomized trials that define the optimal treatment approach for either localized or advanced disease [ 1 ].

They are rare and usually develop slowly over some years. Patients with lcnec are predominantly male, older, and heavy smokers. Restrict diagnosis of large cell carcinoma to resected tumors that lack any clear morphologic or immunohistochemical differentiation (j thorac oncol 2015;10:1243) immunohistochemical markers can reclassify many cases of large cell carcinoma as neuroendocrine, glandular or squamous carcinoma (virchows arch 2014;464:61, am j clin.
