OBJECTIVEThe purpose of this study was to classify the diffuse large B-cell lymphoma (DLBCL) into different prognostic subgroups according to four different detection methods of the expression of CD138, CD10, bcl-6, and MUM1. In particular to investigate the significance of CD138 in immunohistochemical profiles and its correlation with prognosis in DLBCL.
METHODSImmunohistochemical EnVision method was used to detect the expression of CD138, CD10, bcl-6 and MUM1 in 106 cases of DLBCL and reconstructed into four different subtyping algorithms. Algorithm-1, according to the expression of CD10, bcl-6 and MUM1, the cases were assigned to GCB and non-GCB groups. Algorithm-2, according to the expression of CD138, CD10, bcl-6 and MUM1, the cases were assigned to A, B, C, D groups. Algorithm-3, according to the expression of CD10 and MUM1, the cases were assigned to GCB and non-GCB groups. Algorithm-4, according to the expression of CD138, CD10, bcl-6 and MUM1, the cases were assigned to GCB and non-GCB groups. Following up was included as well. Statistical analysis was performed using the SPSS 13.0 and differences were considered significant at P < 0.05.
RESULTSCD138, MUM1, CD10 and bcl-6 were positive in 15.1% (16/106), 56.6% (60/106), 21.7 (23/106) and 26.4% (28/106), respectively. The expression of CD10 and bcl-6 was associated with favorable OS (P = 0.001 and 0.041, respectively), whereas the expression of CD138 was associated with unfavorable OS (P = 0.003). Using multivariate Cox proportional hazards regression analysis, algorithm-1 and -4 were almost at the same level for prognosis of OS (OR = 0.259, 0.255) and PFS (OR = 0.248, 0.244).
CONCLUSIONSBoth Hans's algorithm and Colombo's algorithm including CD138 detection are associated with the prognosis of DLBCL patients. The two algorithms have similar OR value according to Cox analysis. However, positive expression of CD138 is of minor significance in prediction of the prognosis in DLBCL patients.

OBJECTIVETo study the inhibitory effect of zoledronic acid (ZA) on the growth and CD138 expression of myeloma cell line KM3.
METHODSKM3 cells were treated with different concentrations of ZA The growth of KM3 cells was measured by trypan blue dye exclusion, and the changes of apoptosis rate, cell cycle and expression of CD138 induced by ZA by flow cytometry.
RESULTSWithin the concentration of 10(-5)-10(-3) mol/L, ZA obviously inhibited the growth of KM3 cells in a dose dependent manner. IBN at 10(-5)-10(-4) moL/L increased Annexin V positive rate, blocked cells at the S/G2 boundary, reduced the expression of CD138 and its fluorescence intensity.
CONCLUSIONZA can inhibit the growth of KM3 cells in a dose-dependent manner and inhibited CD138 expression. The mechanism is probably related to induction cell cycle accumulation in S phase and apoptosis.

OBJECTIVETo investigate the prevlance of 1q21 amplification in patients with multiple myeloma (MM) and its correlation with the progression and prognosis of the disease.
METHODS1q21 amplification was detected in 48 patients with MM using cytoplasmic light chain immunofluorescence with fluorescence in situ hybridization analysis (cIg-FISH) and interphase fluorescence in situ hybridization (I-FISH) analysis combined with CD138 immunomagnetic cell sorting (MACS).
RESULTS1q21 amplification (≥ 3 red signals) was detected in 26/48(54.2%) cases by cIg-FISH and 31/48 (64.6%) cases by I-FISH combined with CD138 MACS. There was a good consistency between the two methods (P>0.05). The mortality of patients with 1q21 amplification was significantly higher than those without (P< 0.05). No significant difference was detected in terms of sex, age, Durie-Salmon stage, subgroup and international staging system (ISS) stage between patients with 1q21 amplification and those without (P>0.05).
CONCLUSIONThe frequency of 1q21 amplification in MM is high. There was also an association between the amplification and poor prognosis. cIg-FISH is consistent with CD138 MACS combined with I-FISH.

Extramedullary plasmacytoma of the pancreas is a rare entity. Although this condition is uncommon, it should be considered in the differential diagnosis of solid mass in the pancreas, especially in patients with underlying multiple myeloma. We report a case of pancreatic plasmacytoma in a 56-year-old woman with newly diagnosed multiple myeloma. We highlight this rare manifestation of multiple myeloma among other better recognised presentations.

OBJECTIVETo investigate the expression of Notch1 on the membrane of bone marrow CD38(+)CD138(+) plasma cells in the patients with multiple myeloma (MM), and explore the importance of Notch signaling pathway in the formation and progression of MM.
METHODSThirty three MM patients and 15 healthy controls were enrolled in this study. The expression of Notch1 on the membrane of bone marrow CD38(+)CD138(+) and CD38(+)CD138(-) plasma cells were analyzed by flow cytometry. The clinical data of MM patients were also analyzed.
RESULTSThe ratio of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients was (60.21 ± 25.06)% which was significantly higher than those of CD38(+)CD138(-) plasma cells of MM patients (39.84 ± 18.94)% (P = 0.000) and controls (38.34 ± 19.39)% (P = 0.004). There was no statistical difference between the two latter groups (P > 0.05). The expression of Notch1 on CD38(+)CD138(+)plasma cells from 24 newly diagnosed MM patients was correlated to the level of malignant plasma cells in there bone marrow (r = 0.914, P = 0.000), serum level of lactate dehydrogenase (LDH) (r = 0.754, P = 0.007), and β(2)-MG(r = 0.716, P = 0.013). The ratio of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients who had renal dysfunction was correlated to their abnormal serum creatinine levels. The expression of Notch1 on CD38(+)CD138(+) plasma cells from 17 MM patients who received VD (bortezamib and dexamethasone) chemotherapy was correlated to the ratio of plasma cell reduction after the first VD chemotherapy (r = 0.842, P = 0.000).
CONCLUSIONThe expression of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients was significantly higher than those of CD38(+)CD138(-) plasma cells of MM patients and controls. Notch1 overexpressed plasma cells were sensitive to the early VD therapy, and correlated to the progression and long term outcome of MM.

Glycosaminoglycans are important structural components in the skin and exist as various proteoglycan forms, except hyaluronic acid. Heparan sulfate (HS), one of the glycosaminoglycans, is composed of repeated disaccharide units, which are glucuronic acids linked to an N-acetyl-glucosamine or its sulfated forms. To investigate acute ultraviolet (UV)-induced changes of HS and HS proteoglycans (HSPGs), changes in levels of HS and several HSPGs in male human buttock skin were examined by immunohistochemistry and real-time quantitative polymerase chain reaction (qPCR) after 2 minimal erythema doses (MED) of UV irradiation (each n = 4-7). HS staining revealed that 2 MED of UV irradiation increased its expression, and staining for perlecan, syndecan-1, syndecan-4, CD44v3, and CD44 showed that UV irradiation increased their protein levels. However, analysis by real-time qPCR showed that UV irradiation did not change mRNA levels of CD44 and agrin, and decreased perlecan and syndecan-4 mRNA levels, while increased syndecan-1 mRNA level. As HS-synthesizing or -degrading enzymes, exostosin-1 and heparanase mRNA levels were increased, but exostosin-2 was decreased by UV irradiation. UV-induced matrix metalloproteinase-1 expression was confirmed for proper experimental conditions. Acute UV irradiation increases HS and HSPG levels in human skin, but their increase may not be mediated through their transcriptional regulation.

BACKGROUND AND OBJECTIVEInvasion and metastasis are the most common causes of mortality for patients with colorectal neoplasms, and blocking invasion and metastasis in a timely fashion has become a hot research focus. We investigated the expression of the messenger RNA of Syndecan-1 and HPA-1 in colorectal cancer, and their correlation with invasion and metastasis.
METHODSReal-time fluorescent quantitative polymerase chain reaction (PCR) was used to detect the expression of Syndecan-1 and HPA-1 in specimens from 49 patients with colorectal cancer, 49 paired adjacent colorectal neoplasms (2 cm from the carcinoma), and 49 surgical margins of paired normal colorectal mucosa tissue (5 cm from the carcinoma), to analyze their correlation with clinicopathologic characteristics of colorectal neoplasm.
RESULTSThe expression of HPA-1 mRNA was significantly higher in colorectal cancer (40.56 +/- 11.75) than that in the paired adjacent colorectal neoplasms (18.28 +/- 11.33) and normal colorectal mucosa tissue (10.80 +/- 10.20) (all P < 0.001). The expression of HPA-1 mRNA was significantly higher in paired adjacent colorectal neoplasms than that in normal colorectal mucosa (P < 0.05). The expression of Syndecan-1 mRNA was significantly higher in normal colorectal mucosa (61.21 +/- 12.96) than in the paired adjacent mucosa (14.35 +/- 11.06) or colorectal cancer (10.12 +/- 8.58) (all P < 0.001). The expression of Syndecan-1 mRNA was significantly higher in the paired adjacent mucosa than that in colorectal cancer (P < 0.05). The decreased expression of Syndecan-1 mRNA and the increased expression of HPA-1 were closely associated with the degree of differentiation, the depth of infiltration, lymph node metastasis, vessel metastasis, and TNM staging of colorectal cancer (all P < 0.05). Spearman rank correlation analysis demonstrated a significant correlation between Syndecan-1 and HPA-1(r = -0.405, P < 0.05).
CONCLUSIONSThe expression of Syndecan-1 mRNA was significantly highest in normal colorectal mucosa and the expression of HPA-1 mRNA was significantly highest in colorectal cancer. At the same time, the decreased expression of Syndecan-1 mRNA and the increased expression of HPA-1 mRNA can promote the invasion and metastasis of colorectal cancer. The determination of Syndecan-1 and HPA-1 may be of value in the treatment as well as in the prognosis of patients with colorectal cancer.

9.Prognostic Evaluation of Nodal Diffuse Large B Cell Lymphoma by Immunohistochemical Profiles with Emphasis on CD138 Expression as a Poor Prognostic Factor.
Journal of Korean Medical Science 2006;21(3):397-405
Recently diffuse large B cell lymphoma (DLBCLs) was reported to be subdivided into germinal center B-cell-like (GCB) and activated B-cell-like (ABC) subgroups by using cDNA microarray and immunohistochemical markers. Tissue microarray blocks were created from 51 nodal DLBCLs with control tissue. Immunohistochemical staining for the above markers were performed. The median follow-up period was 26 months. Nodal DLBCLs were subclassified into GCB [CD10+ or CD10-/Bcl-6+/MUM1-, n=17 (33%)] and non-GC subgroups [CD10-/Bcl-6- or CD10-/Bcl-6+/MUM1+, n=35 (67%)], and were alternatively subclassified into pattern A [+ for GCB marker only, n=12 (23%)], B [Co-positive for both markers, n=13 (33%)], C [+ for activation marker only, n=18 (35%)], and D [- for both markers, n=9 (17%)]. Upon survival analysis, the GCB groups showed a relatively better survival than non-GC groups (p=0.0748). Also, pattern C (p=0.0055) and CD138+ (p=0.0008) patients had significantly lower survival rates. By multivariate analysis, CD138 expression alone was considered as an independent risk factor (p=0.031). In summary, our results add to the registration of prognostic implications for previously reported DLBCL subgroups. CD138 may play an important role as a poor prognostic marker. By using immunohistochemistry, a prognostically important subclassification of DLBCLs is possible.

Extramedullary plasmacytoma of the larynx is rare, especially when coexisted with squamous cell carcinoma in situ. We report a 56-year-old woman with hoarseness for 6 months and dysphonia for a week. Fiberoptic laryngoscopic examination showed a red, smooth-surface swelling in the submucous region of the left ventricle and ventricular band of the larynx. The patient underwent vertical laryngectomy and modified left neck dissection. Postoperative pathologic examination revealed coexisting plasmacytoma and carcinoma in situ. Bone marrow biopsy and systemic radiogram showed no positive findings. The hepatic and renal functions were normal. Monoclonal immunoglobulin light chain of type kappa was detected in urine. Hence, a laryngeal extramedullary plasmacytoma with carcinoma in situ was diagnosed. No recurrence or progression was observed during a 2-year follow-up. Here, we discussed the risk factors, diagnosis, and therapy for this rare disease.
