Abstract The purpose of this study was to develop a consensus-based computed tomographic (CT) atlas that defines lymph node stations in radiotherapy for lung cancer based on the lymph node map of the International Association for the Study of Lung Cancer (IASLC). A project group in the Japanese Radiation Oncology Study Group (JROSG) initially prepared a draft of the atlas in which lymph node Stations 1–11 were illustrated on axial CT images. Subsequently, a joint committee of the Japan Lung Cancer Society (JLCS) and the Japanese Society for Radiation Oncology (JASTRO) was formulated to revise this draft. The committee consisted of four radiation oncologists, four thoracic surgeons and three thoracic radiologists. The draft prepared by the JROSG project group was intensively reviewed and discussed at four meetings of the committee over several months. Finally, we proposed definitions for the regional lymph node stations and the consensus-based CT atlas. This atlas was approved by the Board of Directors of JLCS and JASTRO. This resulted in the first official CT atlas for defining regional lymph node stations in radiotherapy for lung cancer authorized by the JLCS and JASTRO. In conclusion, the JLCS–JASTRO consensus-based CT atlas, which conforms to the IASLC lymph node map, was established.

AbstractOBJECTIVESThe International Association for the Study of Lung Cancer (IASLC) proposed further subdivisions of pathological N1 (pN1) and pN2 by including the location and the number of involved lymph node (LN) stations. We adopted the subdivided N descriptors and reclassified them according to the involved LN zones or LN stations, and compared the discrimination abilities of the 2 classifications.METHODSA retrospective analysis was carried out on patients who underwent complete resection with systematic LN dissection for non-small cell lung cancer diagnosed as pathological stages I–III between 2006 and 2015. N classification was grouped into 6 categories: no LN involvement, single-station N1, multiple-station N1, single-station N2 without N1, single-station N2 with N1 and multiple-station N2. LN zones were defined by grouping the LN stations: peripheral or hilar for N1 nodes, and upper mediastinal, lower mediastinal, aortopulmonary and subcarinal for N2 nodes.RESULTSA total of 3971 patients (2451 men, median age: 63 years) were analysed. Median follow-up was 59 months. A multivariable analysis showed that the subdivided N descriptors based on LN station and zone were both independent prognostic factors in terms of both overall survival and freedom from recurrence. Whether multiple LN involvements were confined within a single LN zone was a significant prognostic factor in the multiple-station N2 group. A zone-based classification showed similar discrimination ability to the station-based classification.CONCLUSIONSBoth LN station- and zone-based classifications showed favourable prognostic discrimination abilities. The new N classifications could be considered for future revisions of tumour, node and metastasis (TNM) staging system for lung cancer.
