Hilum...defined.......

In my evening of searching about any and all things concerning hilum, what I have surmised is that it is a particular section of a lymph node. So what I am possibly looking at is a cancerous node ? Is this close or way off base...I am simply getting a full grasp of who what when where how and why before the trip to Vandy and Onc concerning protocols...This is what I have found that leads me to believe that it is a particular area of a single node....Someone correct me if I am wrong....You will not upset me, I am here for the input..What I think I have is activity around the effluent end of a node...if this being the case is it not feasible to simply (well maybe not simply) remove the infected nodes ...just asking, Im not sure about anything.....in any case ....here is the literature......and thank you all.......


Lymph nodes are small bean-shaped structures that are usually less than 2.5 cm in length. They are widely distributed throughout the body along the lymphatic pathways where they filter the lymph before it is returned to the blood. Lymph nodes are not present in the central nervous system. There are three superficial regions on each side of the body where lymph nodes tend

to cluster. These areas are the inguinal nodes in the groin, the axillary nodes in the armpit, and the cervical nodes in the neck.

The typical lymph node is surrounded by a connective tissue capsule and divided into compartments called lymph nodules. The lymph nodules are dense masses of lymphocytes and macrophages and are separated by spaces called lymph sinuses. Several afferent lymphatic vessels, which carry lymph into the node, enter the node on the convex side. The lymph moves through the lymph sinuses and enters an efferent lymphatic vessel, which carries the lymph away from the node. Because there are more afferent vessels than efferent vessels, the passage of lymph through the sinuses is slowed down, which allow time for the cleansing process. The efferent vessel leaves the node at an indented region called the hilum.

    From Wikipedia
    "Above and behind the cardiac impression is a triangular depression named the hilum, where the structures which form the root of the lung enter and leave the viscus. These include the pulmonary artery, superiormost on the left lung, the superior and inferior pulmonary veins, lymphatic vessels and the bronchus, with bronchial vessels surrounding it. The pulmonary ligament droops down from the hilum of the lung and terminates in a free, or falciform, edge.

    The area around the hilum is called "perihilar"."

    hilar lymph node
    Buzz,

    It is my hilar lymph node in my right lung that is affected. It has grown and lit up, shrunk and not lit up, and now it's lighting up again. Amazingly, it is the only lymph node that has ever shown up on any of my scans. Even upon my stage IV diagnosis, no lymph nodes were ever found to be affected. They think it initially metastasized through my blood stream, not lymph nodes.

    Anyhow, yes, it is a lymph node. I was told I'm not a candidate for cyberknife or nanoknife or surgery on my lungs because of how very many nodules I have in both lungs. I still wonder if the lymph node being affected could make the possibility of further spread more likely than the other nodules. Hmmm.... something to ask about.

    I like that you're researching all your possibilities. Best wishes to you and prayers always-

    Hugs,
    Lisa

    If in fact it turns out to be the hilar node and it is the only one affected , is there surgery options ? or cyber, nanno, or just chemo treatment ? Im not sure what my best options would be not being real knowledgeble on the hilar yet...assuming that is what it is..would you guess that chemo to try and destroy it would be the best route or maybe a first try at a resolution?...buzz

    This might work
    Buzz,

    I am not sure where I heard this but the chemo Folfiri (with avastin or erbitux) seems to be better at resolving lymph nodes. I am not sure if this is true or not, but mine completely resolved on this treatment. I have also heard that they do not have to be removed and usually won't be unless there is another reason to have surgery. I had three or four lymph nodes that were calcified after treatment and my onc. said no need to remove. The body takes care of that.

    I am praying for you, Buzz. I know you will get through this.

    Hugs,
