In an attempt to decrease catheter drainage of pancreatic pseudocysts, a combined regimen of percutaneous drainage and administration of octreotide acetate was used in eight symptomatic patients. Indications for the combined therapy were pseudocyst recurrence (four patients), pancreatic fistula from percutaneous drainage (two patients), or elective treatment to restrict pancreatic drainage. Octreotide acetate was administered subcutaneously in doses of 50-1,000 micrograms three times a day. The drug was well tolerated and produced only limited adverse effects in four patients: pain at the injection site, hypoglycemia, diarrhea, headaches, and lower-extremity edema (more than one adverse effect was experienced by each patient). The combined use of percutaneous drainage and administration of octreotide was effective in seven patients and failed in one patient who had distal pancreatic duct occlusion. In five patients, catheter drainage decreased to no measurable amount by a mean of 13.8 days. These results suggest octreotide is effective in decreasing the output from pancreatic pseudocysts drained percutaneously.

In this pilot study, the predictive value of Octreotide scintigraphy (Octreoscan) and/or Chromogranin-A (CgA) was investigated in patients with hormone-refractory prostate cancer treated with Octreotide acetate. In total, 20 patients with progressive disease and bone metastases entered the trial. At baseline Octreoscan, CgA, PSA, alkaline phosphates (ALP) and two self-administered questionnaires (EORTC QLQ C-30 (v3) and brief pain index) were performed and a diary of the pharmaceutical was started. The treatment consisted of Octreotide (Sandostatin LAR) acetate 30 mg intramuscular injection every month. The blood samples and questionnaires were repeated every month until 3 months. Clinical responder was defined as a patient with increased global health score more than 10 units and stable or decreased pain score without an increase in analgesic. In all, 17 patients were treated per protocol, and four were assessed as clinical responders. Six patients developed a reduction in ALP (median -26%, range -5 to -78%). All patients increased in PSA. At baseline, three patients had a negative Octreoscan and the patients with positive lesions, demonstrated uptake of low intensity. At baseline the CgA was elevated above the normal range in 15 of the patients, and during treatment five patients decreased their CgA to the normal range. Neither baseline Octreoscan nor CgA could identify the clinical reponders. A minority of patients improves their health-related quality of life. The decrease and normalization of CgA levels in five patients during therapy indicates therapeutic activity but Octreoscan and CgA could not identify clinical responders.

Symptoms of malignant bowel obstruction in patients with recurrent ovarian cancer lead to a poor quality of life. Sandostatin LAR Depot (LAR) is an intramuscular, monthly administered, long-acting form of octreotide. LAR's safety and utility were evaluated in a pilot study enrolling 15 advanced ovarian cancer patients with bowel dysfunction. Once safety with subcutaneous (SQ) octreotide was assessed, patients were given 30 mg LAR on Day 1 and octreotide SQ for 2 weeks. Of 13 evaluable patients, three patients had a major response to LAR treatment with reduction in bowel obstruction symptoms, two had a minor response, four had no response, and four had progressive symptoms. Three patients remained on LAR for more than 9 months. No significant toxicities were attributable to octreotide or LAR. Because three patients received nine or more monthly injections of LAR, possible direct antitumor effects of LAR or synergy with chemotherapy needs to be explored.

Octreotide acetate was developed as a pharmacologically stable, long-acting analogue of the hormone somatostatin. Mimicking the actions of somatostatin, octreotide has been used for its antisecretory effects. Randomized control trials have established the efficacy of octreotide for malignant bowel obstruction and for chemotherapy-induced diarrhea. Octreotide has proven to be an effective agent for symptoms of carcinoid syndrome. Newer uses include for bone marrow transplantation, infectious diarrheal syndromes, and management of hepatic metastases. More evidence is needed for the establishment of its efficacy for hypercalcemia, pain, pleural effusions, diarrhea after celiac plexus block, and malignant ascites.
