Summary

This dataset was generated to train models for research in the Radiation Planning Assistant (RPA), aimed at auto-contouring cervical lymph node levels in the head and neck.

  • Patients: Training = 32 (31 unique); Test = 15
  • Acquisition Protocol: See accompanying spreadsheet (TCIA_RPA_HN_LNs_Aquisition_Protocols) for more details. All patients were imaged supine with head holder and thermoplastic mask specified in our institution’s simulation protocol for radiotherapy head and neck.
  • Scanner Details: Philips/Brilliance Big Bore (89.4%) | SIEMENS/SOMATOM Definition Edge (10.6%)
  • Patient Inclusion Criteria: CT scans of 46 unique patients who retrospectively received head and neck radiotherapy at MD Anderson Cancer Center from April 2019 to June 2021 were curated. All data was gathered under an approved institutional review board protocol. These patients received definitive radiotherapy to the oropharynx with no nodal dissection.
  • Segmentation Generation: First, five head and neck sub-specialized radiation oncologists manually contoured seven lymph node levels (IA, IB, II, III, IV, V, RP (Retropharyngeal or VIIA)) on 3 patients each, totaling 15 patients. This resulted in a collection of 105 lymph node level contours (5 physicians x 3 patients x 7 contours). Left and right contours for each nodal level were combined into one volume to prevent misclassification from left-right flipping augmentations. Contours were anatomically drawn without margin according to institutional practice. This dataset was comprised of images and contours of definitive Oropharynx Cancer (OPX) patients only and did not contain images and contours of those who had nodal level dissections at the time of radiotherapy. These 15 patients’ contours were used to train an initial model. This initial model was then used to generate lymph node level contours on 32 additional CT scans (31 unique patients), which were subsequently edited and reviewed for quality by a radiation oncology resident to be training data for the final model. The 15-patient cohort was then used as test data for the final model. The contours were split into left and right contours in post-processing.
    • Structures of interest: LN_Neck_IA_L, LN_Neck_IA_R, LN_Neck_IB_L, LN_Neck_IB_R, LN_Neck_II_L, LN_Neck_II_R, LN_Neck_III_L, LN_Neck_III_R, LN_Neck_IV_L, LN_Neck_IV_R, LN_Neck_V_L, LN_Neck_V_R, LN_Neck_RP_L, LN_Neck_RP_R
  • Note: In processing the image data, a single patient was accidentally anonymized more than once. The dataset for this model used a duplicate of one of those patients as 2 training subjects. The duplication was discovered after the journal publication. The duplicate anonymized patient IDs are RPA-HN-Lymph-Nodes-006 and RPA-HN-Lymph-Nodes-017. The duplicate was removed from the TCIA dataset; RPA-HN-Lymph-Nodes-006 was removed. Patient ID RPA-HN-Lymph-Nodes-017 may be used twice if the user wishes to duplicate the findings in the journal publication.
