Two colonic mucoid adenocarcinomas in tamarins from the German Primate Centre are reported. A mucinous mucoid adenocarcinoma occurred in the ascending and transversal colon of a Saguinus oedipus male more than 8 years old, with metastases in the regional lymph nodes and the pancreas. The tumour corresponded to colon cancer in cotton-topped tamarins of other colonies. The second tumour, a well differentiated tubular mucoid adenocarcinoma, developed at the ileocaecal valve of a 14½ year old Saguinus fuscicollis male with metastases to the local lymphatic system.

Chemokines are important in the development and progression of tumors. We investigated the expression of CXCL14 and CXCL16 in colon cancer. Expression of mRNA was assessed in primary tumors and lymph nodes and CXCL16 mRNA levels were correlated to patient’s survival. Protein expression was investigated by two-color immunofluorescence and immunomorphometry. CXCL14 and CXCL16 mRNA levels and protein expression were significantly higher in colon cancer primary tumors compared to apparently normal colon tissue. Positive cells were tumor cells, as revealed by anti-CEA and anti-EpCAM staining. CXCL16, but not CXCL14, mRNA levels were significantly higher in hematoxylin and eosin positive (H&E(+)) compared to H&E(−) colon cancer lymph nodes or control nodes (P < 0.0001). CXCL16 mRNA was expressed in 5/5 colon cancer cell lines while CXCL14 was expressed significantly in only one. Kaplan-Meier analysis revealed that colon cancer patients with lymph nodes expressing high or very high levels (7.2 and 11.4 copies/18S rRNA unit, respectively) of CXCL16 mRNA had a decreased mean survival time of 30 and 46 months at the 12-year follow-up (P = 0.04, P = 0.005, respectively). In conclusion, high expression of CXCL16 mRNA in regional lymph nodes of colon cancer patients is a sign of a poor prognosis.

Abstract BackgroundDistribution of regional lymph nodes (LNs) is decisive for the lymphadenectomy boundary in radical resection of a right-sided colon cancer (RCC). Currently, the data of LNs in central area remains ambiguous and scarce. Herein we aim to provide a more detailed anatomical research on LNs surrounding the superior mesenteric vessels for RCC and investigated the metastasis rate.MethodsCarbon Nanoparticles (CNs) or Indocyanine Green (ICG) were used as dye and we laparoscopically observed the stained LNs distribution pattern and analyzed the harvested LNs combined with pathology report. Lastly, 137 RCC patients who received a “superior mesenteric artery (SMA)-oriented” hemicolectomy from September 2016 to September 2020 were included to calculate the probability of LNs metastasis in our target area.Results20 patients diagnosed as RCC (mean age 55.55 years, 13 male) were included. 13 patients underwent CNs injection and 7 patients consented to the ICG, while 4 cases suffered from imaging failure. The unequal number of the regional LNs located between SMV and SMA was detected in 17 cases (85%), posterior to SMV area in 6 cases (30%), and anterior to SMA in 11 cases (55%), respectively. The presence of LNs posterior to SMV was associated with the crossing pattern of ileocolic artery (²= 5.38, p= 0.020). The probability of LNs metastasis in the above areas (target areas) was 2.19% (3/137). No dyed LNs occurred when the SMA sheath was exposed. What’s more, the number of total harvested LNs in patients with dye injection was significant more than dye-free RCC patients (22.44±13.78 vs 43.20±22.70, p<0.01). ConclusionRight-hemi colon-draining lymphatic vessels anteriorly/posteriorly traversed the SMV and arrived at the surface of SMA near the middle colonic artery (MCA) level, which highlights the potential need of CME to place the internal border anterior to SMA and the removal of mesenteric tissue in our target area on lymphatic resection.

The utility of mRNA and protein determinations of G protein-coupled receptor 35, that is, GPR35a (GPR35 V1) and GPR35b (GPR35 V2/3), as indicators of outcome for colon cancer patients after curative surgery was investigated. Expression levels of V1 and V2/3 GPR35, carcinoembryonic antigen and CXCL17 mRNAs were assessed in primary tumours and regional lymph nodes of 121 colon cancer patients (stage I–IV), colon cancer cell lines and control colon epithelial cells using real-time quantitative reverse transcriptase-polymerase chain reaction. Expression of G protein-coupled receptor 35 was investigated by two-colour immunohistochemistry and immunomorphometry. GPR35 V2/3 mRNA, but not V1 mRNA, was expressed in colon cancer cell lines, primary colon tumours and control colon epithelial cells. Haematoxylin and eosin positive (H&E(+)), but not H&E(–), lymph nodes expressed high levels of GPR35 V2/3 mRNA ( P<0.0001). GPR35b and carcinoembryonic antigen proteins were simultaneously expressed in many colon cancer tumour cells. Kaplan–Meier and hazard ratio analysis revealed that patients with lymph nodes expressing high levels of GPR35 V2/3 mRNA and, in particular, in the group of patients with lymph nodes also expressing carcinoembryonic antigen mRNA, had a short disease-free survival time, 67 months versus 122 months at 12-year follow-up (difference: 55 months, P = 0.001; hazard ratio: 3.6, P = 0.002). In conclusion, high level expression of G protein-coupled receptor 35 V2/3 mRNA in regional lymph nodes of colon cancer patients is a sign of poor prognosis.
