Is a full body pet scan good in the diagnosis of lymphoma ?

Is a full body pet scan good in the diagnosis of lymphoma ?

Very good test: Pet/ct is used quite often in the initial diagnosis and restaging of many types of lymphoma. Lymphoma consumes glucose at a much higher rate than normal tissues. That makes pet/ct with f-18 fdg, which images glucose metabolism, is a great test for lymphoma. ...Read more

Can hodgkin lymphoma transform to NHL? After 4 cycle of ABVD, PET showed an area with SUV 14. Initial diagnosis was HL IIb, bulky.

Can hodgkin lymphoma transform to NHL? After 4 cycle of ABVD, PET showed an area with SUV 14. Initial diagnosis was HL IIb, bulky.

Yes it can: This change has been reported, so it is entirely possible. But only a biopsy of the new area or the growing lymph node can determine what is going on. Your oncologist should be able to help address this matter for you. Or you can seek a second opinion from another medical oncologist, if you are not totally satisfied with your current oncologist. ...Read more

What is the definition or description of: pet-ct lymphoma diagnosis?

What is the definition or description of: pet-ct lymphoma diagnosis?

PET/CT staging: Lymphoma is diagnosed by the microscopic appearance of a tumor biopsy. It is further classified by studies of the expression of molecules on the surface of tumor cells (e.g. with antibody staining) and by tumor gene mutation studies. PET/CT on the other hand, is used to determine the "stage" of the disease, meaning its location and how widespread it is. Both are important for optimal treatment. ...Read more

Hodgkin lymphoma,stage IIb, bulky. 130mm,after 8 cycle of ABVD, PET + , hypermetabolic mass and increase its size to 141mm! Why?Is Stanford V helpful?

Hodgkin lymphoma,stage IIb, bulky. 130mm,after 8 cycle of ABVD, PET + , hypermetabolic mass and increase its size to 141mm! Why?Is Stanford V helpful?

Jury not out: There is ongoing trial to answer your question but previous studies suggest ABVD superior. That said, factors such as radiotx and personal immune response to Hodgkin D need to be considered. Fail cases to conventional chemoradiotx appear to respond to immune therapy, ie.

1.5 to 1.9cm, 2 lymph nodes neat suspected thymoma in ant mediastinum. Pet suv was 3.8 for thymoma and 4.7 for 1.9 node. Could it it by lymphoma?

Hard to tell, Biopsy: Only a biopsy can tell the cause of these abnormalities. Unless you have some symptoms from these lesions in the mediastinum, i would be inclined to wait before jumping right now into this area for a biopsy. An interval repeat study pet or ct scan in 2 months would be my preference. Why were all these tests done? Do you have any pain or fever? What is your doctor's recommendation for further step. ...Read more

14 yr old sister had lymphoma 2 yrs ago and now they see something in pet scan in esophagus. What could it be? Please any ideas

See below: You can get physiologic uptake in the esophagus which is normal. It is atypical for lymphoma to recur only in the esophagus. It could periodically be in a lymph node adjacent to the esophagus. I would recommend at least getting an upper endoscopy. ...Read more

Is Full body PET scan or CT scan better for diagnosing Lymphoma? Which uses less radiation?

Is Full body PET scan or CT scan better for diagnosing Lymphoma? Which uses less radiation?

Both: The actual diagnosis of lymphoma requires tissue, usually excisional biopsy of an entire lymph node. Staging to see where other sites of disease could be is done with a combined PET/CT. The staging used to matter more many years ago when they would often give XRT or do surgery, it doesn't matter as much as it used to because almost everybody gets systemic chemotherapy for both Hodkins and non H ...Read more

Can Splenic Marginal zone lymphoma be missed in PET/CT and flow cytometry in early stages ?

Yes: If there is not impressive splenomegaly / enlarge lymph nodes and there are no / few lymphoma cells in the blood, it will be impossible to make the call, and probably not even possible to suspect the illness. ...Read more
