CA125 is an antigenic determinant recognized by monoclonal antibody CA125 raised against a serous ovarian cancer cell line. Elevation of this antigen has been reported in over 80% of women with epithelial ovarian cancer and many other diseases including both malignant and non-malignant ones. However, in non-Hodgkin's lymphoma (NHL) only a few reports have focused on this topic thus interesting us. In order to exploit its possible role in this field, a total of 61 eligible patients with a diagnosis of NHL were studied. Serum CA125 was measured by radioimmunoassay (RIA) prior to any operative procedures or chemotherapy. Serum CA125 above 35 U/ml was seen in 47.7% of nodal NHL (n = 44) and 70.6% of extranodal NHL (n = 17) with an overall positive rate at 54.1%. The elevation of serum CA125 correlates well with the presence of peritoneal involvement and therefore, with disease extent to some degree. No correlation between it and the histological type or with the B symptom was the rule. Avidin-biotin peroxidase stain by anti-CA125 MoAb was applied to identify the tissue content of this antigen in 15 cases of whom 11 had CA125 well above 35 U/ml. None of the 15 cases examined showed positive result. In conclusion, serum CA125 is probably no more than an indicator of peritoneal stimulation released by tumor invasion rather than a tumor product. The possible role in disease follow-up remains to be elucidated.

The present study investigated the possible clinical significance of serum CA125 levels in patients with non-Hodgkin's lymphoma (NHL) and the mechanism of secretion. Serum CA125 levels in 335 patients with NHL were measured by enzyme-linked immunosorbent assay. The tissue CA125 expression in 22 patients with NHL was performed on paraffin section by immunohistochemical methods. One hundred and ninety-eight cases (59.1%) were found to have elevated serum CA125 levels. Serum CA125 levels were associated with clinical stage, effusions, high serum lactate dehydrogenase and beta2-M levels, and response to therapy. Microscopically, immunohistochemical staining revealed that malignant tumor cells demonstrated negative CA125 expression in all of the 22 cases. Our results suggested that serum CA125 levels could be an interesting tumor marker in NHL. The immunohistochemical study suggested that CA125 appeared not to be secreted by lymphoma cells directly.

We aimed to evaluate the prognostic value of the combination of three serum tumor markers (LDH, beta2-M and CA 125) in patients with non-Hodgkin's lymphoma (NHL). Clinical and pathological variables including the levels of these markers were measured in 415 NHL patients. Statistical analysis showed that increased levels of all three markers were associated with stage, B symptoms, effusions, bone marrow involvement, and International Prognostic Index (IPI) in NHL patients (p<0.05). Overall survival and event-free survival rates were associated not only with LDH but also with beta2-M and CA125 (p<0.001). Response to treatment and overall survival rates were different in three groups with elevated LDH; in particular, the combination of three or two elevated markers seemed to identify a group of patients at higher risk of treatment failure and/or relapse than the group with a high LDH level only. Furthermore, multiple Cox regression analysis showed that IPI score complemented by the additional serum markers beta2-M and CA125 was a better prognosticator of overall and event-free survival than LDH alone. This result suggests that if the combination of three elevated serum tumor markers is included as a parameter in the IPI instead of LDH alone, the prognostic value of IPI can be improved.

The initial aim of this study was to identify novel serum diagnostic markers for the human ovarian granulosa cell tumor (GCT), a tumor that represents up to 5% of all ovarian cancers. To circumvent the paucity of human tissues available for analyses, we used the Ctnnb1(tm1Mmt/+);Pten(tm1Hwu/tmiHwu);Amhr2(tm3(cre)Bhr/+) transgenic mouse model, which features the constitutive activation of CTNNB1 signaling combined with the loss of Pten in granulosa cells and develops GCTs that mimic aggressive forms of the human disease. Proteomic profiling by mass spectrometry showed that vinculin, enolase 1, several heat shock proteins, and valosin containing protein (VCP) were more abundantly secreted by cultured mouse GCT cells compared to primary cultured GC. Among these proteins, only VCP was present in significantly increased levels in the preoperative serum of GCT cancer patients compared to normal subjects. To determine the specificity of VCP, serum levels were also measured in ovarian carcinoma, non-Hodgkin's lymphoma and breast, colon, pancreatic, lung, and prostate cancer patients. Increased serum VCP levels were observed in the majority of cancer cases, with the exception of patients with lung or prostate cancer. Moreover, serum VCP levels were increased in some GCT, ovarian carcinoma, breast cancer, and colon cancer patients who did not otherwise display increased levels of widely used serum tumor markers for their cancer type (e.g. inhibin A, inhibin B, CA125, CEA, or CA15.3). These results demonstrate the potential use of VCP as highly sensitive serum marker for GCT as well as several other human cancers.
