Dendritic cells (DCs) play an important role in immune reactions. This study was designed to identify the distribution patterns of DCs and regulatory T-cells (Tregs) in cutaneous lymphomas.
Immunohistochemistry was used to determine langerin expression on Langerhans cells, CD11b on inflammatory DCs, CD209 and CD11c on dermal DCs, CD303 on plasmacytic DCs, and Foxp3 on Tregs in 81 cases of cutaneous lymphomas.
Various DCs and Tregs were identified in most cutaneous lymphomas. Plasmacytic DCs, inflammatory DCs and Tregs were identified mainly in tumor areas, whereas dermal DCs were distributed both in the tumor and stromal areas. Among DCs, dermal DCs were most prominently identified in the cutaneous lymphomas not only in the tumor area but also in the stroma. The intense stromal infiltration of dermal DCs was consistent finding in T-cell lymphomas. Diffuse large B-cell lymphoma (DLBCL), not otherwise specified also showed intense stromal infiltration of dermal DCs, but stromal infiltration in DLBCL, leg type was relatively scant.
The results suggest that all types of DCs and Tregs are involved in cutaneous lymphoma tumor immunity. Among them dermal DCs may play a dominant role.

Growing tumors adapt to a hypoxic environment and increase anaerobic glycolysis. This metabolic switch is related to aggressive behavior. We investigated the relationship between glycolytic metabolism biomarkers associated with hypoxia-inducible factor (HIF)-1alpha and prognosis.
We performed immunohistochemical staining of HIF-1alpha, pyruvate dehydrogenase kinase (PDK) 1 and lactate dehydrogenase (LDH) 5 in 74 patients with oral squamous cell carcinoma (SCC) who had received curative radical resection.
High reactivity of HIF-1alpha, PDK 1 and LDH 5 was observed in 29 (39.2%), 32 (43.2%) and 54 (73.0%) patients, respectively. Expression levels of the three biomarkers were significantly correlated. All three markers were highly expressed in 16 (21.6%) patients. Elevated expression of the three markers was associated with increased invasiveness (p = 0.043) and recurrence (p = 0.017) of tumors. In survival analysis, upregulation of the three markers was additionally associated with shorter disease free survival (DFS, p = 0.001) and overall survival (OS, p = 0.002). High expression of all three markers was a strong independent prognostic factor for DFS (p = 0.030) and OS (p = 0.026).
Oral SCC with altered glycolytic metabolism exhibits a more invasive and aggressive phenotype. Our results indicate that glycolytic metabolism biomarkers related to HIF-1alpha may be independent prognostic factors in patients with oral SCC.

AbstractAbstract PDF
: Mucin phenotypic markers and CDX2 are widely expressed in gastric carcinomas, however, recent studies have produced conflicting results regarding whether the expression patterns of these markers have clinicopathologic significance.
: We examined samples from 217 gastric carcinoma patients immunohistochemically to determine if the expression of mucin phenotypic markers and CDX2 was correlated with postoperative survival and other clinicopathologic factors.
: All tumors were phenotypically classified as gastric (type G, 81 cases), gastric and intestinal mixed (type GI, 55 cases), intestinal (type I, 43 cases), or unclassified (type U, 38 cases). The occurrence of type G and GI tumors was positively correlated with tumor progression whereas that of type U tumors was negatively correlated with tumor progression. CDX2 expression was correlated with type I tumors. Tumors that expressed MUC5AC or MUC6 had a better prognosis than those that did not. When the relationship between phenotype and prognosis was considered, type GI had the best prognosis, followed by type G, then type U.
: The mucin phenotypic markers may be useful for predicting tumor progression and survival in patients with gastric carcinomas. Additionally, CDX2 may play an important role in gastric carcinogenesis of type I tumors.
