Several haematological findings (especially the values of serum LDH and its isoenzymes) were compared with changes in the gastrin level in pernicious anaemia. While vitamin B12 substitution therapy led to normalization of the anaemia and of the enzyme levels, gastric atrophy and, hence, the elevation in serum gastrin levels remained unchanged. Determination of serum gastrin, therefore, provides a valuable tool for the verification of the diagnosis of pernicious anaemia in treated cases.

A few recent reports suggest the protective effect of antacids against gastric mucosal injury. This study was aimed to examine the influence of some antacids on ethanol induced gastric mucosal damage in rats. We have found that Polish antacids (Alugastrin, Gelatum Aluminii Phosphorici, Gastrin) and calcium carbonate diminished gastric mucosal lesions produced by ethanol. Moreover, Alugastrin and Gelatum Aluminii Phosphorici decreased volume of gastric contents, and its pH, as well as lowered sodium, potassium and protein levels and decreased LDH activity in gastric contents. These findings indicate that antacids protect rat gastric mucosa against injury caused by ethanol. We have found also that aspirin given prior to Alugastrin abolished the protective ability of Alugastrin. This suggest that prostaglandins might be involved in antacid cytoprotection. Our studies indicate that antacids can be used prophilactically in the gastric mucosal injuries.

Blood enzymatic activities in gastric carcinoma depend on the release from carcinomatous tissues, surrounding non-neoplastic tissues, increased permeability and necrosis of carcinomatous tissues. However, those enzymatic activities did not parallel the extent and macroscopic appearance of the tumor. Various enzyme proteins and gastrointestinal hormones concerning gastric carcinoma and intestinal metaplasia including pepsin, LDH, AFP, beta-glucuronidase, rGTP, lysozyme, ferritin, sialic acid, polyamine, CEA, Ca 19-9, collage, gastrin, immunoglobulin are discussed in this paper. The variation of enzymes and proteins occurring in gastric carcinoma and intestinal metaplasia are well documented. Some of them would be a useful indicator of diagnosis and treatment as a tumor marker.

This retrospective study aimed at determining the prognostic significance of neuroendocrine markers chromogranin A (CgA), pro-gastrin releasing peptide (ProGRP) and neuron-specific enolase (NSE), together with the cytokeratin 19 marker CYFRA 21-1 in small cell lung cancer (SCLC). A total of 148 histologically proven and previously untreated SCLC patients were included. Among them 118 patients received a cisplatin-etoposide combination or cisplatin-etoposide-cyclophosphamide-4'-epidoxorubicin combination. All tumour markers were tested using immunoradiometric assays except for ProGRP which was tested using an enzyme-linked immunosorbent assay. The thresholds for marker serum titrations were 53 pg/ml, 65, 17, and 3.6 ng/ml for ProGRP, CgA, NSE and CYFRA 21-1 respectively. Univariate analysis showed that patients affected by one of the following characteristics proved to have a significant shorter survival in comparison with the opposite status of each variable: age over 63 years, extensive-stage, serum LDH level higher than 600 U/l, serum NSE level higher than 17 ng/ml, serum CgA level higher than 65 ng/ml and serum CYFRA 21-1 level higher than 3.6 ng/ml. In addition, there was a trend towards a statistical significance for a high serum alkaline phosphatase level and a performance status equal to or worse than two. The following variables were independent determinants of a poor outcome: a poor performance status (hazard ratio [95% confidence interval]: 1.51 [1.02-2.22]), a high CgA level (HR: 1.61 [1.06-2.45]), a high CYFRA 21-1 level (HR: 2.10 [1.40-3.14]) and an age older than 63 years (HR: 1.68 [1.14-2.48]). When the multivariate analysis was restricted to patients receiving a cisplatin-etoposide-based chemotherapy, the same variables were prognostic determinants with nearly similar hazard ratios. In conclusion, aside classical variables such as age and performance status, high serum CYFRA 21-1 and high serum CgA level in SCLC are both prognostic determinants of prognosis, in particular in patients receiving conventional chemotherapy consisting of cisplatin and etoposide-based combinations.
