Dataset Card for The Cancer Genome Atlas (TCGA) Multimodal Dataset

The Cancer Genome Atlas (TCGA) Multimodal Dataset is a comprehensive collection of clinical data, pathology reports, slide images, molecular data, and radiology images for cancer patients. This dataset aims to facilitate research in multimodal machine learning for oncology by providing embeddings generated using state-of-the-art models including GatorTron, MedGemma, Qwen, Llama, UNI, SeNMo, REMEDIS, and RadImageNet.

• Curated by: Lab Rasool

Example code for loading HF dataset into a PyTorch Dataloader. Note: Some embeddings are stored as buffers due to their multi-dimensional shape.

from datasets import load_dataset
import os
from torch.utils.data import Dataset
import numpy as np

class CustomDataset(Dataset):
    def __init__(self, hf_dataset):
        self.hf_dataset = hf_dataset

    def __len__(self):
        return len(self.hf_dataset)
    
    def __getitem__(self, idx):
        hf_item = self.hf_dataset[idx]
        embedding = np.frombuffer(hf_item["embedding"], dtype=np.float32)
        embedding_shape = hf_item["embedding_shape"]
        embedding = embedding.reshape(embedding_shape)
        return embedding

if __name__ == "__main__":
    
    # Load clinical embeddings from different models
    clinical_gatortron = load_dataset("Lab-Rasool/TCGA", "clinical", split="gatortron")
    clinical_llama = load_dataset("Lab-Rasool/TCGA", "clinical", split="llama")
    wsi_dataset = load_dataset("Lab-Rasool/TCGA", "wsi", split="uni")
    
    # Example: Access embeddings
    for index, item in enumerate(clinical_gatortron):
        embedding = np.frombuffer(item.get("embedding"), dtype=np.float32).reshape(item.get("embedding_shape"))
        print(f"GatorTron embedding shape: {embedding.shape}")  # Shape: (1024,)
        break
        
    for index, item in enumerate(clinical_llama):
        embedding = np.frombuffer(item.get("embedding"), dtype=np.float32).reshape(item.get("embedding_shape"))
        print(f"Llama embedding shape: {embedding.shape}")  # Shape: (2304,)
        break

Dataset Creation

Data Collection and Processing

The raw data for this dataset was acquired using MINDS, a multimodal data aggregation tool developed by Lab Rasool. The collected data includes clinical information, pathology reports, and whole slide images from The Cancer Genome Atlas (TCGA). The embeddings were generated using the HoneyBee embedding processing tool, which utilizes foundational models such as GatorTron, MedGemma, Qwen, Llama, and UNI.

Who are the source data producers?

The source data for this dataset was originally collected and maintained by The Cancer Genome Atlas (TCGA) program, a landmark cancer genomics project jointly managed by the National Cancer Institute (NCI).
