Overview

Adenocarcinoma of the lung may be classified according to WHO into 5 subtypes: mixed, acinar, papillary, bronchioloalveolar carcinoma, and solid adenocarcinoma.[1] Adenocarcinoma of the lung may be classified according to IASLC/ATS/ERS into 6 subtypes: pre-invasive lesions, atypical adenomatous hyperplasia, adenocarcinoma in situ, minimally invasive adenocarcinoma, invasive adenocarcinoma, and variants of invasive adenocarcinoma.

Classification

  • Adenocarcinomas are highly heterogeneous tumors. Several major histological subtypes are currently recognized by the WHO[1] and IASLC/ATS/ERS[2][3][4]
  • In as many as 80% of tumors that are extensively sampled, components of more than one of these subtypes will be recognized. Using increments of 5% to describe the amount of each subtype present, the predominant subtype is used to classify the whole tumor.[5] The predominant subtype is prognostic for survival after complete resection.[6]

2004 WHO classification

  • Mixed subtype
  • Acinar
  • Papillary
  • Bronchioloalveolar carcinoma
  • Non mucinous
  • Mucinous
  • Mixed
  • Solid adenocarcinoma
  • Colloid
  • Fetal
  • Mucinous cystadenocarcinoma
  • Signet-ring
  • Clear-cell

IASLC/ATS/ERS classification

  • Pre-invasive lesions
  • Atypical adenomatous hyperplasia
  • Adenocarcinoma in situ of lung
  • Non-mucinous
  • Mucinous
  • Mixed
  • Minimally invasive adenocarcinoma
  • Non-mucinous
  • Mucinous
  • Mixed

  • Papillary predominant
  • Micropapillary predominant
  • Solid predominant with mucin production
  • Variants of invasive adenocarcinoma
  • Invasive mucinous adenocarcinoma
  • Colloid
  • Fetal
  • Enteric
