Are para-aortic lymph nodes cancerous?
Stage IV gastric cancer with para-aortic lymph node metastasis (PALM) is considered an unresectable metastatic disease, and its prognosis remains poor after isolated surgical treatment [2]. The best clinical practice for patients with clinical PALM has remained controversial for over 10 years [3].
What causes enlarged para-aortic lymph nodes?
They may become enlarged because of primary or secondary causes. Primary causes include things like infections or cancers that develop in the lymph nodes. Secondary causes include conditions affecting nearby organs like the kidneys or pancreas.
What is para-aortic lymphadenopathy?
Introduction. The para-aortic lymph nodes (PANs) are located around the abdominal aorta and inferior vena cava and are the regional lymph nodes of the intraperitoneal organs.
Can para-aortic lymph nodes be biopsied?
Paraaortic lymph node biopsy is a controversial but proved technique to determine the extent of the spread of cancers from the uterine cervix or endometrium. Its impact on patient survival is still under extensive investigation.
How are para-aortic lymph nodes treated?
Although para-aortic lymph node metastasis is defined as distant metastasis, these patients are frequently treated with radiation therapy, which can lead to cure (5-7).
Where is a lymph node biopsy done?
A lymph node biopsy is often done in an operating room in a hospital or at an outpatient surgical center.
Can you remove para-aortic lymph nodes?
This surgery, also called lymph node dissection, may be done to examine the pelvic and para-aortic lymph nodes for endometrial cancer cells. Removing and checking the cancerous lymph nodes will let the doctor know the exact stage and grade of the cancer. And it may reduce the spread of the disease.
What is para-aortic lymph node metastasis?
Paraaortic lymph node (PAN) metastasis is considered an important prognostic factor in several abdominal and pelvic malignancies, such as stomach cancer, colorectal cancer, cholangiocarcinoma, and cervical cancer[1-4].
Can a needle biopsy detect lymphoma?
Most doctors do not use needle biopsies to diagnose lymphoma. But if the doctor suspects that your lymph node is enlarged because of an infection or by the spread of cancer from another organ (such as the breast, lungs, or thyroid), a needle biopsy may be the first type of biopsy done.
What is para aortic lymphadenectomy?
Right-sided para-aortic lymphadenectomy is performed by dissecting the lymph nodes of the precaval and paracaval area up to the level of the origin of the right ovarian vein in the inferior vena cava (IVC) or the right renal vein.
How many para aortic lymph nodes are there?

What blood work indicates lymphoma?
Complete blood count (CBC). This test measures the number of blood cells in a sample, including red blood cells, white blood cells, and platelets. A low level of red blood cells, white blood cells or platelets may indicate that the lymphoma is present in the bone marrow and/or blood.
