Immunohistochemical analyses of normal human pancreata revealed weak immunoreactivity for CB1 and CB2 in pancreatic acini, nerves, blood vessels and ductal cells data not shown.
Subsequently, CB receptor immunoreactivity on pancreatic cancer tissues was semiquantitatively evaluated and a combined score staining intensity multiplied by the percentage of the stained area was calculated.
Apart from the staining in the normal parts of the pancreatic cancer tissues, we observed CB1 and CB2 immunopositivity of stellate cells particularly in the vast areas of desmoplasia. Additionally, infiltrating mononuclear cells were immunopositive for CB2.
In cancer cells of pancreatic cancer tissue samples, heterogeneous immunoreactivity was observed: For CB2, there was a low staining score in 18 samples and a high immunoreactivity score in 19 tissues. Furthermore, cancer cells within single tissue samples showed various extents of CB1 and CB2 staining, ranging from no immunoreactivity to strong immunoreactivity Figs.
Consecutive sections which were incubated with the primary antibodies and the corresponding blocking peptide showed the specificity of the staining Figs. Cannabinoid receptor immunostaining in human pancreatic cancer tissues.
Low a , g , moderate b , h and strong c , i immunostaining for CB1 or CB2 receptors in pancreatic cancer cells, respectively. The median survival in the group with low CB1 staining in cancer cells was 16 months, versus 6 months for the group with a high combined CB1 staining score. Since all patients were resectable, none had distant metastases at the time of the operation. CB1 receptor levels correlate with survival.
CB receptor cancer cell protein levels as well as whole tissue mRNA expression levels were evaluated. These analyses confirmed the results of the immunohistochemistry and revealed that higher CB1 mRNA expression levels above median were associated with a shorter survival Fig. Figures 3 d —3 f and 3 j —3 l show the corresponding negative controls which were incubated with the primary antibodies and the corresponding blocking peptide.
The median survival of patients with low cancer cell FAAH was 10 months as compared to Similarly, patients with low MGLL survived in median only 8 months whereas patients with moderate-to-strong MGLL staining in pancreatic cancer cells had a median survival of This may be due to the low number of cancer cells in pancreatic cancer tissue specimens which mainly consist of a fibrotic reaction—desmoplasia.
Enlarged nerves in pancreatic cancer tissues were heterogeneously stained using anti-CB1 and anti-CB2 antibodies Figs. Immunoreactivity of CB1 was generally more pronounced than that of CB2, while both antibodies mainly stained the perineurium of the pancreatic nerves. In some nerves with strong CB1 staining, highly positive ganglia were found Fig. Cannabinoid receptor immunoreactivity of nerves in pancreatic cancer. Low a , g , moderate b , h and strong c , i immunostaining for CB1 or CB2 receptors, respectively, in nerves of pancreatic cancer tissues.
Median survival was 11 months for patients with low pain scores and To determine potential correlations between CB receptor levels and the extent of pain, PDAC patients were stratified according to low or high CB receptor levels in pancreatic nerves no staining: A clinical pain score was available for 27 of 40 patients.
For CB1, 18 out of 27 tissue specimens showed low receptor levels in nerves, whereas for CB2, 21 out of 27 demonstrated low receptor staining intensities. Since low CB1 receptor levels were associated with increased survival but at the same time with a high pain score, we tested a potential general relationship between pain and survival in our patient collective.
A log-rank test of patients with low and high pain scores revealed a statistically significant difference in survival median survival 11 months in the group with low pain scores versus Out of the remaining 29 samples, 11 samples showed no immunoreactivity Fig. Figures 6 d —6 f and 6 j —6 l show the corresponding negative controls for which the primary antibodies were pre-adsorbed with the respective blocking peptide.
To test whether FAAH and MGLL are associated with pain in pancreatic cancer, a quantitative evaluation of the immunoreactivities of these enzymes was carried out. Cannabinoids are used more frequently than earlier as supportive drugs in the palliative treatment of a variety of cancers.
The development of cannabinoid derivatives is a renaissance in medicine, since natural cannabinoids had been used by many societies until their prohibition at the beginning of the last century due to their addictive potential. However, the potential for addiction and psychotropic side effects seems to be by far overestimated, especially for patients with malignant tumors, for whom pain control, stable weight and quality of life are the main measures of medical therapy.
Cannabinoids have just recently been shown to exert growth inhibitory properties in pancreatic cancer. Although there was no difference in endocannabinoid levels between healthy people and patients suffering from pancreatic cancer, cannabinoid receptors, FAAH and MGLL levels showed a significant variation.
Despite heterogeneous staining intensities, levels of cannabinoid receptors were generally upregulated in pancreatic cancer suggesting an active role of these receptors in pancreatic carcinogenesis. In contrast to our findings in acute pancreatitis where there was upregulation of the endocannabinoid system, we did not find any changes in endocannabinoid levels in pancreatic cancer tissues.
This may be due to the low number of samples tested but may also reflect the strong desmoplastic reaction in pancreatic cancer. In the vast areas of peritumoral desmoplasia, the proportion of cancer cells to stroma decreases. Therefore, although the endocannabinoid system seems not to be influenced by pancreatic cancer, one may speculate that the local concentrations of endocannabinoids in the vicinity of the tumor cells might be significantly altered.
