What is Transcoelomic spread?

Transcoelomic spread refers to a route of tumor metastasis across a body cavity, such as the peritoneal cavity, as in the case of ovarian cancer.

What is hematologic spread?

(HEE-muh-TAH-jeh-nus) Originating in the blood or spread through the bloodstream.

What is meaning of metastatic spreading?

(meh-TAS-tuh-sis) The spread of cancer cells from the place where they first formed to another part of the body. In metastasis, cancer cells break away from the original (primary) tumor, travel through the blood or lymph system, and form a new tumor in other organs or tissues of the body.

How does Transcoelomic spread occur?

Transcoelomic spread describes the spread of a malignancy into body cavities that occurs via penetrating the surface of the peritoneal, pleural, pericardial, or subarachnoid spaces. For example, ovarian tumors can spread transperitoneally to the surface of the liver.

What is a hematogenous spread?

distributed or spread by way of the bloodstream, as in metastases of tumors or in infections; blood-borne.

How do cancers spread?

When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.

Does metastatic mean malignant?

Metastasis means that cancer spreads to a different body part from where it started. When this happens, doctors say the cancer has “metastasized.” Your doctor may also call it “metastatic cancer,” “advanced cancer,” or “stage 4 cancer.” But these terms can have different meanings.

What is lymphatic permeation?

Permeation is the growth of a colony of tumor cells along the course of the lymphatic vessel. This commonly occurs in the skin lymphatics in carcinoma of the breast and in the perineural lymphatics in carcinoma of the prostate.

What is hematogenous seeding?

Hematogenous osteomyelitis originates in the metaphysis of tubular long bones adjacent to the epiphyseal growth plate. Thrombosis of the low-velocity sinusoidal vessels from trauma or embolization is considered the focus for bacterial seeding in this process.
