Guest guest Posted March 18, 2010 Report Share Posted March 18, 2010 CLL and SLL refer to malignant B-cell lymphocytes exclusively. When you refer to T-CLL do you mean T-prolymphocytic leukemia (T-PLL)? The term T-CLL was used back in the 1980, but has been dropped. See : http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1577366/ http://www.jimmunol.org/cgi/content/abstract/126/6/2205 PLL used to be lumped in with CLL/SLL but was separated out in about 2002, since the treatments are different.

Guest guest Posted March 18, 2010 Report Share Posted March 18, 2010 Thank you for your interest, but all I have to go on is my original diagnosis letter from my Hematologist at the time. I'll quote an excerpt for you."... I thought he definitely had Chronic Lymphocytic Leukemia and appeared to have some large granular lymphocytes which are often associated with people who have Rheumatoid Arthritis. I recommended that initially we do flow cytometry of his peripheral blood, and this in fact confirmed a marked increase in Cytotoxic T-cells. I then had him get gene rearrangement studies performed of his peripheral blood, which confirmed a rearrangement in the T-cell receptor. There is no doubt that he has a T-cell CLL, and this is likely associate with his Rheumatoid Arthritis." .. I am also confused because my current Hemotologist tells me I have NK Killer Cell CLL. That based on the same lab information from 1990.This is why I believe I have T-Cell CLL. The treatments for B Cell CLL to not really apply to my form of CLL. I am still wondering why there appears to be a discrimination by not including this subset of the CLL universe in the CLL discussions.Thanks,Gerald On Mar 18, 2010, at 5:01 PM, cllcanada wrote: CLL and SLL refer to malignant B-cell lymphocytes exclusively.

Guest guest Posted March 18, 2010 Report Share Posted March 18, 2010 What a tumour is and what it is called is designated by the World Health Organization series on histological and genetic typing of tumours. All medicine follows these classifications. CLL and SLL now ONLY refer to B cell malignancies These people classify what the tumours are and which ones are lumped together. The medical report you have dates from 1990. Since then many tumours and cancers have been reclassified several times. It truly is not discrimination, but rather you are a victim of reclassification. You should go to a haematologist and get a new FLOW cytometry done as well as a FISH test. These test will nail down, in current terms, exactly what you have. Relying on report from 1990 is simply foolish. ~chris Here is the excerpt about T CLL being reclassified as T-PLL. " In 1989, the French-American-British (FAB) ative Group distinguished five subgroups of T cell leukemia, namely, T cell CLL, T cell PLL, human T lymphotropic virus type I-positive (HTLV-I+), adult T cell leukemia/lymphoma, and Sézary syndrome. When a new entity called large granular lymphocytic leukemia was defined (see Chap. 94), the existence of T cell CLL as a distinct entity became a topic of debate. Because of this finding, the World Health Organization commissioned a panel of experts to draft a new classification of the hematologic neoplasms. At a meeting in November 1997, the panel proposed a categorization of peripheral T cell neoplasms that largely was based on the Revised European-American Lymphoma (REAL) classification (see Chap. 90). However, because of its aggressive clinical behavior, T cell CLL was reclassified under the heading of T cell PLL, without regard to subtle differences in morphology. Even together they account for less than 5 percent of all chronic lymphoid leukemias.

Guest guest Posted March 18, 2010 Report Share Posted March 18, 2010 I had no idea there was a reclassification as you described below. Thanks for shedding some light on this.Since I have been in good health and in Watch and Wait for 20 years, I got rather complacent about researching my disease. Now that my Platelets are dropping below 100, I have a lot more urgency. I have subscribed to the ACOR CLL list for well over a dozen years and never really heard any such discussion about reclassifications. I am just trying to get smart enough to be able to ask all the right questions when I see my Hematologist next week. Can you provide me with any more references concerning the new classifications?Thanks,Gerald On Mar 18, 2010, at 6:43 PM, cllcanada wrote: What a tumour is and what it is called is designated by the World Health Organization series on histological and genetic typing of tumours.

Guest guest Posted March 18, 2010 Report Share Posted March 18, 2010 Gerald T-CLL is the old nomenclature. What you have is T-cell LGL leukemia. LGL stands for large granular lymphocytic. It is associated with rheumatoid arthritis and patients often have a large spleen. It is much rarer than CLL, though minor forms of it are much commoner than people realize. Fortunately most people require no treatment for it. The most likely complication is a low neutrophil count which can lay you open to bacterial infections.

Guest guest Posted March 19, 2010 Report Share Posted March 19, 2010 Gerald - CIG's position is certainly not against any other form of CLL, other than B-cell. It is simply that the overwhelming percentage are just that. So if you posted here, you might get no intelligent replies from patients, except from the docs we have on the group. So, by all mean post, and Dr. Furman our medical adviser will respond, also perhaps Dr. Hamblin who has recently joined our group. In a message dated 3/18/2010 5:42:58 P.M.

Guest guest Posted March 19, 2010 Report Share Posted March 19, 2010 Dr. Hamblin and Gerald As I have been diagnosed with CLL and finished a 6 round FCR last April. Diagnosed with CLL in June 2007. I also have Still's Disease, which started out when I was 7 and is an obscure form of juvenile rheumatoid arthritis (which the less fortunate get with a much bigger fury when they are adults rather than first getting it as children) this association between the LGL leukemia and rheumatoid arthritis is something new to me. Wow. Of course, Dr. Rai, my CLL guru, tells me that I am good fodder for a medical journal write up. Can anybody out there point me to something that I can read on this?
