We evaluated levels of insulin-like growth factor-I and interleukin-1 alpha and beta in patients with pancreatic cancer; the role of these substances in tumor spread and in hyperglycemia was also investigated. Thirty pancreatic cancer patients (21 with hyperglycemia) were compared with others with diseases causing hyperglycemia [liver cirrhosis (14 cases, 12 with hyperglycemia), chronic pancreatitis (20 cases, 12 with hyperglycemia),
type I diabetes mellitus
(13 cases, all hyperglycemic)]. Insulin-like growth factor-I was significantly reduced in patients with liver cirrhosis, probably due to a reduced hepatic capacity for synthesis. It was increased in 6 of 30 pancreatic cancer patients; in these subjects it was correlated with alanine aminotransferase and C-peptide, but not with tumor diameter or the presence of metastases. Interleukin-1 alpha and beta were both elevated in pancreatic cancer patients. The former was high, while the latter was low when
liver metastases
were present. Neither was related to glucose or C-peptide levels. In summary, insulin-like growth factor-I levels are increased in some pancreatic cancer patients but this does not seem to favor tumor spread; however IGF-I could be involved influencing glucose homeostasis. Interleukin-1 alpha increased, while interleukin-1 beta decreased in pancreatic cancer patients with metastases, suggesting a different involvement of these two substances in pancreatic cancer spread.

The pathogenetic mechanism underlying glucose intolerance in pancreatic cancer is still unclear. We studied the pattern of three glucose regulating hormones (C-peptide, glucagon and GH) in pancreatic cancer patients with (N = 34) and without (N = 8) hyperglycemia, and compared the findings made with those from subjects with other hyperglycemic conditions of well-known origin [
type I diabetes mellitus
(8 cases) and diabetes mellitus secondary to chronic pancreatitis (13 cases) or liver cirrhosis (4 cases)]. In hyperglycemic pancreatic cancer patients, C-peptide was absent in 26% of the cases, reduced in 24%, elevated in 29% and within the normal range in the remaining 21%. In normoglycemic pancreatic cancer this hormone was reduced in two cases (25%) and within the normal range in all the others. GH was within the normal range in all cases: glucagon was below the normal range in some hyperglycemic pancreatic cancer patients (41%) or within the normal range in all the remaining patients. No correlations were found between the three hormones when findings from subjects were considered all together. However, in pancreatic cancer C-peptide and glucagon presented consensual variations. C-peptide, glucagon and GH levels were not related to tumor volume; glucagon was found to be associated with
liver metastases
. C-peptide was correlated with serum ALT and ALP. We may conclude that hyperglycemia associated with pancreatic cancer may be caused by different mechanisms. In some cases a reduced secretion of both insulin and glucagon was observed, as occurs in chronic pancreatitis. In the majority of patients, beta cell function appears normal, and the hyperglycemic state may depend on an altered peripheral sensitivity to insulin due to the pancreatic pathology itself or to consensual liver involvement.

A 68 year old Ecuadorian man was investigated for polyuria, polydipsia and weight loss of 3 kg during the previous two months.
Insulin dependent diabetes mellitus
was diagnosed 10 year before admission and treated with appropriate diet and insulin (35 U/d). 18 months before was diagnosed in El Ecuador of "multiple liver nodes non-suggestive of malignancy". Physical examination showed a large multinodular petrous hepatomegaly. There was no evidence of skin lesions. Results of laboratory studies included a basal plasma glucose level that ranged between 275-367 mg/dl (N=60-100), glycosylated haemoglobin of 8.9% (N<5) and a serum albumin of 2.8 gr./dl (N=3.4-4.8). At admission non-other laboratory alterations were detected. Computed tomography showed a mass on the head of the pancreas with loco-regional lymph nodes and
liver metastases
. Tumor markers were normal. Fine-needle aspiration cytology of the liver masses revealed the presence of
liver metastases
of a non-differentiated malignant tumor. A 111In-DTPAOC scintigraphy revealed the presence of somatostatin receptors in the
liver metastases
, also detecting the presence of multiple bone metastases in the axial and appendicular skeleton. Plasma glucagon level was 678 pg/ml (N<250). A diagnosis of metastatic glucagonoma was established and therapy with streptozocin, 5-FU, insulin and synthetic somatostatin analogs was initiated. Three months after the therapy initiation the patient was symptom free. Some weeks after the patient suffered from left hip pain, and a control 111In-DTPA scintigraphy showed progression of his bone metastases. In conclusion, glucagonoma must be suspected in all diabetic patients with metastatic liver, even in absence of necrotic migratory erythema. In these circumstances, plasmatic glucagon level and somatostatin receptors scintigraphy will be a useful tool for establishing the final diagnosis.

Blood mononuclear cells consist of T cells and monocyte derived cells. Beside immunity, the blood mononuclear cells belong to the complex tissue control system (TCS), where they exhibit morphostatic function by stimulating proliferation of tissue stem cells followed by cellular differentiation, that is stopped after attaining the proper functional stage, which differs among various tissue types. Therefore, the term immune and morphostatic system (IMS) should be implied. The TCS-mediated morphostasis also consists of vascular pericytes controlled by autonomic innervation, which is regulating the quantity of distinct tissues
in vivo
. Lack of proper differentiation of tissue cells by TCS causes either tissue underdevelopment,
e.g
., muscular dystrophy, or degenerative functional failures,
e.g
.,
type 1 diabetes
and age-associated diseases. With the gradual IMS regression after 35 years of age the gonadal infertility develops, followed by a growing incidence of age-associated diseases and cancers. Without restoring an altered TCS function in a degenerative disease, the implantation of tissue-specific stem cells alone by regenerative medicine can not be successful. Transfused young blood could temporarily restore fertility to enable parenthood. The young blood could also temporarily alleviate aging diseases, and this can be extended by substances inducing IMS regeneration, like the honey bee propolis. The local and/or systemic use of honey bee propolis stopped hair and teeth loss, regressed varicose veins, improved altered hearing, and lowered high blood pressure and sugar levels. Complete regression of stage IV ovarian cancer with
liver metastases
after a simple elaborated immunotherapy is also reported.
