An increase in the serum copper (Cu++) level has been described as a sensitive index of disease activity in several hematologic and nonhematologic malignancies. In order to explore the diagnostic value of Cu++ compared to other hematochemical parameters frequently abnormal in malignancies, Cu++, serum alpha2 globulin (alpha2), plasmatic fibrinogen (Fibr), the erythrocyte sedimentation rate (ESR), and serum iron (Fe++) have been detected and evaluated in 267 patients affected with the following diseases: Hodgkin's lymphoma (HL), non-Hodgkin's Lymphomas (NHL), Acute Leukemias (AL), Chronic Myeloid Leukemia (CML), Chronic Lymphocytic Leukemia (CLL), Myeloma (MM), and Breast Cancer (BC). The best correlation between Cu++ increase and disease activity has been found in HL, NHL, AL, and BC. In these diseases, when the considered parameters were compared, Cu++ and ESR showed a similar pattern, i.e., a high frequency of abnormalities in active disease. It is concluded that Cu++ represents a good complement to some other aspecific parameters in evaluating the activity and diffusion of neoplasias and the therapeutic results, particularly in HL, NHL, AL and BC.

14 patients with osteolytic bone disease due to breast cancer or myeloma, 7 of whom had hypercalcaemia, received oral treatment with (3-amino-1-hydroxypropylidene)-1, 1-bisphosphonate (A.P.D.). Serum-calcium dropped to low normal values in all 14 patients, accompanied by a decrease in urine calcium and hydroxyproline excretion-rate. The results show that A.P.D. may inhibit tumour-induced osteolysis.

Urinary adenosine -3' ,5' - cyclic monophosphate was measured in 14 patients with hypercalcaemia not caused by primary hyperparathyroidism. Increased levels were found in patients with malignant disease without bone metastases and believed to be examples of paraendocrine syndrome. Decreased levels were found in patients with metastatic carcinoma involving bone, and in patients with multiple myeloma, lymphoma and immobilisation after fracture. Results obtained during treatment for hypercalaemia are described in three patients. In two hypercalcaemic patients (one with hyperthyroidism and one with breast cancer with bone metastases) normal levels were found. This measurement is a useful substitute for assay of serum parathyroid hormone and is of value in the diagnosis of hypercalcaemia, in monitoring effects of treatment and in revealing underlying mechanisms.

The 25,000 dalton protein of Mason-Pfizer monkey virus (MPMV) was isolated by gel filtration chromatography. In agreement with results from other laboratories, antisera to type-C and the non-type-C bovine leukemia and equine infectious anemia viruses did not precipitate 125I-labelled MPMV p25. In addition, these viruses did not cross-react in a competition radioimmunoassay for MPMV p25. Twenty-one human tissues (15 breast carcinomas, 2 normal breasts, 3 acute myelogenous leukemias and 1 sarcoma) were fractionated by detergent solubilization, ammonium sulfate precipitation, and DE-52 anion exchange chromatography. These methods were shown to be highly effective for purification of MPMV p25. Under assay conditions which minimized incubation damage to the 125I-MPMV p25, all tissues failed to react in the competition radioimmunoassay (RIAT). Two hundred and two human sera or plasma specimens, including those from patients with breast cancer and 33 age-matched controls, from 50 patients with hematologic malignancies, from 12 patients with amyotrophic lateral sclerosis, and from 14 patients with systemic lupus erythematosis, were examined for antibodies to MPMV p25. With the exception of two multiple myeloma plasma which produced artifactual false positive reactions based on hypergammaglobulinemia, a known complication of salt precipitation radioimmunoassays, the remainder of the specimens were negative for evidence of MPMV p25 antibodies.

Ferritins are a group of isometric proteins having an important function in iron storage and metabolism and are found in high concentration in the liver, spleen and bone marrow. Acidic isoferritins are found in human fetal liver, primary mammary, gastric and pancreatic carcinomas, and are termed carcinofetal ferritins. Elevated levels of serum ferritin were found in patients with various malignant diseases such as Hodgkin's disease, chronic myeloblastic, granulocytic and lymphatic leukemias and myeloblastosis, in patients with breast cancer, multiple myeloma, malignant lymphoma, carcinoma of the gastro intestinal tract and germinal cell tumors of the testis. Recently a subpopulation of circulating T lymphocytes bearing surface ferritin was found in patients with breast cancer and untreated Hodgkin's disease. No such lymphocytes were demonstrated in normals or in patients with benign breast disease. The appearance of such subpopulation in the circulation is an early manifestation of the neoplastic disease, and its identification may provide a tool of potential diagnostic and prognostic importance in the management of Hodgkin's disease and breast cancer.

From the Third National Cancer Survey (TNCS) Interview Study of 7,518 incident cases, lifetime histories of occupations and industries were studied for associations with specific cancer sites and types while controlling for age, sex, race, education, use of cigarettes or alcohol, and geographic location. Lung cancer patients were found more often than expected among several categories including trucking, air transportation, wholesaling, painting, building construction, building maintenance, and manufacturing (furniture, transportation equipment, and food products). Controlling for cigarette smoking did not change these associations. Leukemia and multiple myeloma were associated with sales personnel of both sexes, whereas lymphomas and Hodgkin's disease were excessive among women working in the medical industry. Other associations included rectal cancer with several retail industries; prostate cancer with ministers, farmers, plumbers, and coal miners; malignant melanoma with school teachers; and invasive cervical cancer with women working in hotels and restaurants. Breast cancer patients were more common among women who were teachers or other professionals and who worked in business and finance (even after controlling for education). Many other findings are presented in detailed tables. Results are reported mainly as a research resource for use by other investigators doing work in this field. Suggestions are given for future studies.

Glucocorticoids are often included with other agents in cancer treatment although the mode of action is not clear. They are useful in the primary combination chemotherapy of both acute and chronic lymphocytic leukaemias, Hodgkin's and non-Hodgkin's lymphomas, multiple myeloma and breast cancer. Other uses for glucocorticoids in cancer patients include an anti-inflammatory action for the oedema of cranial and spinal metastases, a weak antihypercalcaemic effect and the ability to suppress tumour-related fever.

Intracisternal A particles (IAPs) are retrovirus-like structures consistently observable in a variety of mouse tumor cells such as myeloma and hybridoma and in early embryonic cells derived from rodents but nothing is known of their infectivity. Mouse IAPs contain a gag-like protein, a reverse transcriptase and a polyadenylated RNA molecule (IAP RNA). DNA sequences complementary to IAP RNA (IAP genome) are interspersedly present in rodent such as mice, rats, Chinese hamsters and Syrian hamsters at several hundred to a thousand copies per haploid genome. Molecularly cloned IAP genomes from two species Mus and Syrian hamster were 6 to 8 kb in length with LTRs of about 0.4 kb long. The nucleotide sequence of the Syrian hamster IAP genome, H18, predicted a typical LTR-gag-prt-pol-env-LTR structure, although many stop codons were present in the region corresponding to env. The comparison of the deduced amino acid sequences of the pol region showed IAP (type A), mouse mammary tumor virus (MMTV) (type B), and squirrel monkey retrovirus (SMRV) (type D) genomes to be closely related. By using a DNA fragment encoding the pol region of the Syrian hamster IAP genome, human endogenous retroviruses termed HERV-K, were cloned from a fetal human liver gene library. Typical HERV-K genome was 9.5 kb in length having LTRs of about 1.0 kb. The HERV-K provirus could encode gag (666 codons), prt (334 codons), pol (937 codons), and env (618 codons) genes. HERV-K was shown to be closely related to types A, B and D retroviruses. The HERV-K genomes are present at about 50 copies per haploid human genome. In several human tumor cell lines, the HERV-K genome was expressed as 8.8 kb poly(A)+ RNA which appeared to be a full-size transcript of this genome. In the human breast cancer cell line T47D, stimulation of HERV-K genome expression was observed following female steroids treatment. In a detailed investigation on the organization of HERV-K proviruses in human genome, we found repetitive sequences homologous to the LTR region of the HERV-K genome. They were about 630 bp in length with an A rich tail at 3' end and found to be a SINE type nonviral retroposon. These elements were present at 4,000 to 5,000 copies per haploid human genome.

Mitoxantrone is a dihydroxyanthracenedione derivative which as intravenous mono- and combination therapy has demonstrated therapeutic efficacy similar to that of standard induction and salvage treatment regimens in advanced breast cancer, non-Hodgkin's lymphoma, acute nonlymphoblastic leukaemia and chronic myelogenous leukaemia in blast crisis; it appears to be an effective alternative to the anthracycline component of standard treatment regimens in these indications. Mitoxantrone is also effective as a component of predominantly palliative treatment regimens for hepatic and advanced ovarian carcinoma. Limited studies suggest useful therapeutic activity in multiple myeloma and acute lymphoblastic leukaemia. Regional therapy of malignant effusions, hepatic and ovarian carcinomas has also been very effective, with a reduction in systemic adverse effects. Mitoxantrone inhibits DNA synthesis by intercalating DNA, inducing DNA strand breaks, and causing DNA aggregation and compaction, and delays cell cycle progression, particularly in late S phase. In vitro antitumour activity is concentration- and exposure time-proportional, and synergy with other antineoplastic drugs has been demonstrated in murine tumour models. Leucopenia may be dose-limiting in patients with solid tumours, whereas stomatitis may be dose-limiting in patients with leukaemia. Other adverse effects are usually of mild or moderate severity although cardiac effects, particularly congestive heart failure, may be of concern, especially in patients with a history of anthracycline therapy, mediastinal irradiation or cardiovascular disease. Mitoxantrone displays an improved tolerability profile compared with doxorubicin and other anthracyclines, although myelosuppression may occur more frequently. Thus, mitoxantrone is an effective and better tolerated alternative to the anthracyclines in most haematological malignancies, in breast cancer and in advanced hepatic or ovarian carcinoma. Further studies may consolidate its role in the treatment of these and other malignancies.

BCA200 has been described as a 200,000 Mr monomeric cell surface glycoprotein associated with human breast cancer. Since the physical properties and cellular distribution of BCA200 resemble those of c-erbB-2, antibodies to BCA200 were tested for the ability to bind a recombinant protein containing the c-erbB-2 extracellular domain (erbB-2 ECD). Three antibodies to distinct epitopes of BCA200 reacted with erbB-2 ECD but not with a control protein expressed in a similar baculovirus lysate. Control myeloma proteins and antibodies to four other antigens did not react with erbB-2 ECD. A protein with the expected molecular weight for erbB-2 ECD was also immunoprecipitated by anti-BCA200 antibody 520C9. We conclude that BCA200 is another synonym for c-erbB-2.
