Hello!
I fed that bit of you report into chatGPT this is what it reported:
Tumor invades adventitia and/or perigastric adipose tissue
Adventitia:
This is the outermost layer of tissue surrounding organs like the stomach or esophagus.

If a tumor reaches the adventitia, it means it has penetrated all the way through the wall of the organ.

Perigastric adipose tissue:
This is the fat tissue that surrounds the stomach.

If tumor cells are found here, it means the cancer has spread into the fatty tissue around the stomach.

🧾 What this usually means:
The cancer is not confined to just the lining or wall of the stomach or esophagus—it has invaded nearby tissues, which may indicate a more advanced stage.

This kind of invasion is often consistent with T3 or T4 in TNM staging (Tumor, Node, Metastasis), depending on the exact structures involved.

🩺 Why it matters:
The extent of tumor invasion helps determine the stage of cancer.

This staging helps doctors decide the best treatment options (surgery, chemo, radiation) and gives some idea about prognosis.
