A prospective study of 149 patients suffering from adenocarcinoma of unknown primary site (ACUPS) of bone was carried out. The tumors are classified as 63 extraspinal, 67 spinal and 19 mixed involvement. Upon meticulous physical examination, Virchow's node was detected in 15 cases, rectal shelf in 11 cases and hepatomegaly in 44 cases. Blood chemistry showed elevation of alkaline phosphatase (> 3 sigma units) in 98 cases and chest roentgenogram showed pulmonary lesions in 23 cases. Treatment was surgery and radiotherapy in 64 and two cases respectively. In all of these patients histological findings of the biopsy or resection specimen had confirmed the diagnosis of adenocarcinoma. Among 124 evaluable patients, overall survival was analysed using Kaplan-Meier life table analysis. Survival rates at one, two and four months after diagnosis were 80.7, 60.5 and 25 per cent with a mean and median survival times of 90 and 77 days respectively. Statistical analysis was also performed to ascertain the prognostic importance of the following variables: age, gender, Virchow's node, rectal shelf, hepatomegaly, serum alkaline phosphatase, pulmonary lesion, and multiplicity and site of the osseous lesions. The presence of pulmonary lesion or hepatomegaly significantly produced unfavorable impact on the duration of survival (p = 0.0004 and 0.0150, respectively) while other remaining factors had not.

We report on our experience investigating the serum levels of the soluble domain of p185 and the neu protein expression in the corresponding tumour tissue in patients with advanced gastrointestinal carcinomas. The study included 32 patients who were treated with palliative chemotherapy. The serum levels of the neu protein were investigated by immunosorbent assay techniques. We used the alkaline phosphatase/anti-(alkaline phosphatase) method for investigating the corresponding tumour tissue immunohistochemically. Increased serum neu protein levels were found in 8 of 22 (36%) patients with colorectal carcinomas and in 2 patients with advanced abdominal adenocarcinoma of unknown primary. All other patients with advanced gastrointestinal cancers were serum-neu-protein-negative. All serum-neu-protein-positive patients with colorectal carcinomas showed also an elevated neu protein expression. The extent of serum neu protein expression corresponded to the clinical course and the tumour marker CA 19-9. The serum neu protein may be useful for monitoring patients with advanced colorectal carcinomas, particularly in cases of immunohistochemical neu-protein-positive primary tumours.
