LUAD-CT-Survival (Long and Short Survival in Adenocarcinoma Lung CTs)

40 contrast-enhanced chest CT scans of lung adenocarcinoma patients from the H. Lee Moffitt Cancer Center, each with an expert-seeded primary-tumor segmentation and a binary survival-outcome label (long- vs short-survivor). This is the segmentation-ready HuggingFace mirror.

Dataset Details

Field	Value
Modality	CT (contrast-enhanced, pre-surgical)
Body part	Lung (primary adenocarcinoma tumor)
Task	3D binary tumor segmentation (foreground = tumor)
Cases	40 (single cohort, no official train/val/test split)
Survival labels	20 Long, 20 Short (outcome quartiles)
Image format	NIfTI .nii.gz (converted losslessly from original DICOM)
Mask format	NIfTI .nii.gz, binary {0,1} (tumor = 1)
License	CC BY 3.0
Source	TCIA, DOI 10.7937/K9/TCIA.2017.0tv7b9x1

Format note (reformatted variant)

The original TCIA distribution ships the CT images as DICOM and the tumor masks as uncompressed NIfTI with values 0/255. This mirror converts each DICOM series to .nii.gz with SimpleITK (voxel data, spacing, origin and direction preserved) and binarizes the masks to {0, 1}. Image↔mask geometry was verified identical (same shape / spacing / origin) before binarization; any case needing it has its mask nearest-neighbour resampled onto the image grid, so every masks/<id>.nii.gz is defined on exactly its images/<id>.nii.gz grid.

Ground truth

One tumor mask per case, produced by a semi-automatic region-growing algorithm with radiologist-placed seed points. There is a single annotation tier — it is the gold-standard reference (no multi-rater or auto-vs-expert variants).

⚠️ Cross-dataset overlap (benchmark-leakage hazard)

LUAD-CT-Survival is a TCIA analysis-result collection: its masks and survival labels are original, but the 40 CT image series are drawn from two other Moffitt TCIA collections:

• 37 cases — QIN LUNG CT (patient IDs R0xxx)
• 3 cases — LungCT-Diagnosis (QIN-LSC-0009, QIN-LSC-0014, QIN-LSC-0064)

patient_id in metadata.csv equals the original TCIA PatientID and is the cross-reference key. Exclude these patient IDs before benchmarking against QIN-LUNG-CT or LungCT-Diagnosis. (The NBIA API currently files all 40 series' Collection as "QIN LUNG CT"; the three QIN-LSC-* IDs trace to LungCT-Diagnosis per the source publication, recorded in source_collection.)

Structure

images/<patient_id>.nii.gz    # CT volume
masks/<patient_id>.nii.gz     # binary tumor mask (tumor = 1)
metadata.csv                  # patient_id, survival_label, source_collection,
                              #   num_slices, spacing_x/y/z, tumor_voxels
FeaturesWithLabels.csv        # original TCIA radiomic features + survival_label (verbatim)
