Approach to Lung Neoplasm-Primary vs Metastasis: Short Review

摘要

Lung cancer is a very serious problem of the Indian subcontinent, especially in the lower socioeconomic subgroups. As per the ICMR registry of 2002, in Indian population lung cancer is the 5th most common tumour and 2nd most common tumour in the males. It accounts for 6.9% of new cancer cases detected each year. Since lung is a metastatic site for almost all the cancers in the body there is a great confusion in diagnosing a primary from metastasis or pleural tumour. Hence, this short review aims to throw some light on the salient features and the approach. All pubmed indexed articles present online and in English were read and then summarised in this paper. There were many overlaps morphologically in pleural tumours, lung primary and metastasis and morphology apart IHC and molecular factors play a great role in its diagnosis as is discussed in the article.
