Objectives:
Investigating relationships between potential occupational risk factors and lymphoid malignancy (LM).
Methods:
We conducted a multicenter hospital-based case-control study in France between 2000 and 2004, including 824 incident cases of non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), multiple myeloma, and "lymphoproliferative syndrome" and 752 frequency-matched controls. Data were collected through face-to-face standardized and detailed interviews.
Results:
Farming was significantly associated with NHL (odds ratio [OR] = 1.4 [1.0 to 2.0]) and, although not significantly, with lymphoproliferative syndrome and multiple myeloma. ORs were higher for longest durations of exposure. Self-declared exposure to pesticides was significantly associated with NHL (OR = 1.8 [1.2 to 2.7]) and HL (OR = 2.2 [1.0 to 4.7]). Neither solvent-related jobs nor self-reported exposure to solvents were related to LM. Systematic screening based on job titles did not evidence any other association.
Conclusions:
The results support the hypothesis that farming plays a role in most types of LM.

01:15Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
01:27Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
