Updates

  • 02/12/2024: included GPT4o summarized prompts.

1. Usage Tutorial:

Here is a colab tutorial for model testing, please click here.

2. Descriptive Prompt Generation

Generate descriptive prompt on two levels: slide-level and patch-level. Templates for questioning on LLM (GPT-4) are:

Patch-level + Postive(EBV):

Q1: Please provide a summary of the factors found in primary tumor whole slide images that may indicate Epstein-Barr Virus (EBV)-positive subtype of Gastric cancer, along with a description of their image features in short terms, separated by semicolons. Please avoid using subtype names in your response.
Q*: Please avoid using the word "EBV" in your response.
Q*: Please give more.

Patch-level + Negative(others):

Q2: Suppose we let Gastric cancer subtypes other than Epstein-Barr Virus (EBV)-positive subtype into one group. Please provide a summary of the factors found in primary tumor whole slide images that may indicate this group of subtypes, along with a description of their image features in short terms, separated by semicolons.
Q*: Please avoid using the word "EBV" in your response.
Q*: Please give more.

Slide-level + Postive(EBV):

Q3: Summary the appearance of whole slide images of Epstein-Barr Virus (EBV)-positive subtype of Gastric cancer in short terms, separated by semicolons.
Q*: Please avoid using the word "EBV" in your response.
Q*: Please give more.

Slide-level + Negative(others):

Q4: Suppose we let Gastric cancer subtypes other than Epstein-Barr Virus (EBV)-positive subtype into one group. Summary the appearance of whole slide images of this group in short terms, separated by semicolons. 
Q*: Please avoid using the word "EBV" in your response.
Q*: Please give more.

Write these answers with format as the following: (columns="prompt_level,label,descriptive_prompt")

patch,ebv,Lymphoid stroma: Dense lymphoid stroma with infiltrating lymphocytes; lymphocytes surrounding tumor cells.
patch,ebv,Lymphoepithelioma-like appearance: Undifferentiated tumor cells with abundant lymphocytic infiltrate; tumor cells interspersed with lymphocytes.
patch,ebv,Epstein-Barr Virus (EBV)-encoded RNA (EBER) expression: Strong and diffuse nuclear staining for EBER; intense staining in the nuclei of tumor cells.
...
slide,ebv,Lymphocyte-rich infiltrate; Well-defined glandular structures; Epithelial cell apoptosis; Nuclear atypia; Syncytial growth pattern; Presence of viral-associated features; Intense lymphoid reaction; Absence of signet ring cells; Expression of viral RNA.

Next, run the helper script to parse these prompts into JSON format. The primary functions included within the helper scripts are:

  • split prompts into two file based on its level (slide vs.patch)
  • avoid using class label(or associated keywords)
  • filter the top-N concepts of patch-level prompts

Note: EXPERIMENT_NAME is the same as created in main.py.

EXPERIMENT_NAME=molecular_ebv_others_full_train python tools/parse_prompt.py
