The relative usefulness of a combination of some tumor markers, such as CEA, AFP, ferritin and NSE for the diagnosis of lung cancer was assessed by multiple logistic analysis. Serum concentration of these markers was determined in 68 patients with lung cancer (50 with NSCLC and 18 with SCLC, in 68 patients with benign lung disease and 75 normal control subjects. Ferritin proved to be the most useful in diagnosing both NSCLC and SCLC, while NSE was found to be of some help in diagnosing SCLC only. The multiple marker panel proved to be more sensitive and specific than any single marker in discriminating lung cancer from normal control tissue, but it was of limited value in discriminating malignant from benign lung disease. The results of the present study would suggest that the panel of investigated tumor markers is not of great help for the early diagnosis of lung cancer.

In 111 thyroid cancer patients consisting of 89 papillary carcinomas, 17 follicular carcinomas, 2 medullary carcinomas, 1 squamous cell carcinoma and 2 malignant lymphomas, the levels of 12 tumor markers, including thyroglobulin (Tg), were measured in the serum by radioimmunoassay and radioimmunoassay related methods. Serum levels of Tg were elevated in 58.6%, those of CA-M26 in 15.7%, CA 19-9 in 5.3%, CT in 3.6%, NSE in 3.6%, CA 15-3 in 2.6%, CA 125 in 2.6%, CEA in 0.9%, CA-M 29 in 0%, ferritin in 0%, SCC in 0% and AFP in 0% of cases. Among the patients, there was a case of thyroid carcinoma secreting thyroglobulin and CA 19-9, both of whose titer decreased after surgery. Immunohistochemical studies were carried out on 57 of the above mentioned patients plus 6 anaplastic carcinomas, 15 adenomas, 5 adenomatous goiters, 6 Hashimoto's thyroiditis, 15 Graves' disease and 15 normal subjects. CA 19-9 was positive in 58% of the papillary carcinomas, EGF in 73% of papillary carcinomas, 67% of anaplastic carcinomas, and 33% of follicular carcinomas, while EGF-R was found in 73% of the papillary carcinomas, and 33% of the follicular carcinomas. Enhanced expression of ras p 21 oncogene and (c-myc oncogene) was demonstrated in 100% (100%) of anaplastic carcinomas, in 100% (67%) of follicular carcinomas and in 63% (90%) of papillary carcinomas. Our results indicate that a better tumor marker is required and more extensive molecular oncology research should be pursued.

The usefulness of tumor-associated trypsin inhibitor (TATI) in the diagnosis of various solid tumors was compared to other tumor markers occurring in serum and urine (CEA, CA19-9, CA125, CA72-4, CA50, CA15-3, CA72-4, NSE, TPA, AFP, CK-BB and ferritin). TATI was particularly well suited for the diagnosis of tumors of the pancreas, ovary, oesophagus and bladder. For tumors of these organs TATI may be considered the marker of choice. TATI was also a good marker for distinguishing between disease with or without liver metastasis in cancer of the colon and the breast.

The prognosis of advanced neuroblastoma is extremely poor. We treated 5 patients with advanced neuroblastoma, older than 3 years, with multimodal therapy including intraoperative irradiation and autologous bone marrow transplantation. Elevated serum NSE and ferritin level and unfavorable histology according to the Shimadas histological classification, all of which are indicators of poor prognosis, were found in all of them. N-myc oncogene was amplified in 3 cases. After preoperative intensive induction chemotherapy, delayed primary operation and intraoperative irradiation (10-15 Gy) were performed. The postoperative lethal dose chemotherapy and total body irradiation (33 Gy x 3 days) were followed by autologous bone marrow transplantation. Tumor cells were purged using immunomagnetic beads method. Two cases showed recurrence (brain; 1, bone and bone marrow; 1) and a metastatic brain tumor was extirpated completely. All of them are alive during the follow up period from 6mo. to 4y8mo. (mean; 2y5mo.) with no evidence of disease except one. It may be concluded that our multimodal therapy is effective in achieving better results for advanced neuroblastoma.

A direct two-site binding assay on the basis of antibodies from sheep for the quantification of human gamma-gamma enolase is described. The antibody was produced by immunization with human NSE coupled to horse spleen ferritin. The assay shows two feature: a decreased reactivity with NSE from rat and NSE from human serum in spite of 100% recovery of purified human brain NSE. The sheep antibody seems to react with epitopes less accessible on the rat NSE and on the NSE of human serum. The assay is characterized by gamma-gamma enolase specificity, a high sensitivity (2 pg) and a precision of CV = 3-7%.

Malignant fibrous histiocytomas (MFH) belong to the most frequent soft tissue tumours in adults and have to be discriminated from other tumours with similar morphology. Various tumour markers aid the differential diagnosis. Twenty cases of MFH were studied immunohistochemically using antibodies to vimentin, TPA, desmin, lysozyme, alpha 1-antitrypsin, alpha 1-antichymotrypsin, S-100 protein, neurone-specific enolase (NSE), laminin, fibronectin and ferritin. Vimentin and lysozyme were found in the tumour cells of all, alpha 1-antitrypsin of 18, alpha 1-antichymotrypsin of 19, fibronectin of 16 and ferritin of 12 cases. Antibodies of TPA, desmin, S-100 protein, NSE and laminin did not reveal positive immunoreactivity. Exclusion of spindle-cell carcinoma can be made by positive vimentin and negative TPA reactivity, of melanoma by negative S-100 reactivity, and of leio- and rhabdomyosarcoma by lack of desmin immunoreactivity. Schwannomas contain S-100 protein, but lack lysozyme, alpha 1-antitrypsin, alpha 1-antichymotrypsin and fibronectin. Pleomorphic liposarcomas cannot be distinguished from MFH on the basis of immunohistochemical staining. Vimentin, alpha 1-antitrypsin, alpha 1-antichymotrypsin and fibronectin can, therefore, be regarded as useful markers in the differential diagnosis of MFH.

Within the past few years, the measurement of serum and tissue markers has had an increasing influence on clinical decisions about initial treatment and follow-up. Lung cancer illustrates the types and importance of these various markers. This review presents data concerning the most studied and interesting markers in non-small cell (NSCLC) and small cell lung cancer (SCLC). CEA, TPA, SCC-Ag, CYFRA 21-1, ferritin, CA19-9, CA50, CA242, H-K-N-ras mutations and p53 mutation seem to be the most prolific in NSCLC, while NSE, BN/GRP, CK-BB, NCAM, IL-2R, IGF-I, transferrin, ANP, mAb (cluster 5), Le-y and c-N-L-myc mutation are markers in SCLC patients. Some of these serum markers might be useful adjuncts for monitoring response to therapy, including early detection of tumour reactivation to allow curative therapy and rapid detection of treatment failure to allow change of the regimen. The study of these markers also may lead to a better understanding of the biological characteristics of lung cancer. The information derived from these biological studies represents the most promising avenue towards new treatment strategies, as well as attempts at secondary prevention.

Of 567 children with neuroblastoma diagnosed between November 1984 and May 1993 in 21 Italian institutions, 235 (41%) have been evaluated for MYCN oncogene amplification. The amplification (3 or more copies of the gene) was found in 39 patients (17%) and was more frequent in patients aged more than one year, abdominal primary site of the tumor, advanced stages, normal urinary excretion of vanillylmandelic acid (VMA), and high level of LDH, NSE and ferritin. The five-year survival of the 235 patients (62%) was significantly better in patients with normal copy number of MYCN (69% versus 29%). By correlating genomic amplification with clinical and biochemical characteristics, MYCN amplification was found associated with a worse prognosis even when patients were subdivided for age (under and above one year), disease extension (localized operable, localized but inoperable, and disseminated) with exception for Stage IV-S, VMA and homovanillic acid excretion, serum levels of NSE and ferritin, but not of LDH. These data confirm the unfavourable prognostic meaning of MYCN amplification, but are unable to define if it represents a new independent variable.

Serum levels of CEA, NSE and ferritin were monitored during cytostatic chemotherapy in 53 small cell lung cancer patients. Complete remission of cancer was correlated with normalization of CEA and NSE but not of ferritin levels. The lack of normalization of CEA and NSE levels, but not of ferritin level were connected with bad prognosis.

Several biologic features of tumor cells correlate closely with a favorable or unfavorable outcome. To aid in assessing correlation in the various number of prognostic factors including the age, stage, VMA/HVA ratios, and the serum levels of NSE and ferritin, the histopathological features, ploidy, partial monosomy for the short arm of chromosome 1, and the tumor N-myc gene copy number, are examined. We determined the sensitivity and specificity of classical markers above the amplification of the N-myc oncogene. A striking new observation is the positive correlation between genomic amplification and some prognostic factors (stage, ferritin, NSE, pathologic anatomy and 1p deletion.
