In 36 patients with neoplastic diseases 72 episodes of hypercalcaemia with serum-calcium levels greater than or equal to 2.75 mmol/l were treated (19 breast carcinoma; 9 bronchial or lung carcinoma; 5 multiple myeloma; 1 each jejunal carcinoid, malignant lymphoma, phaeochromocytoma). Cardinal symptoms were mental, neuromuscular and renal during the hypercalcaemic episodes. Mithramycin is preferred to other methods (infusion of sodium chloride and frusemide, prednisone, sodium-potassium-phosphate infusion) of treating acute or subacute hypercalcaemia. Mithramycin in a single injection of 20-25 microgram/kg body-weight intravenously is usually sufficient to counteract a hypercalcaemic phase for at least 7-10 days, often much longer. There was a highly significant fall in serum-calcium levels from two days onwards after mithramycin injection. Toxic side-effects were minimal and restricted to transitory increase in transaminase levels, initially 5-6 times normal with a maximum on the third day and normalisation on the fifth day after mithramycin administration.

Interferons produced by recombinant DNA technology began phase I trials little more than a decade ago. Today interferon alfa-2 is a mainstay in the treatment of hairy cell leukemia, and has demonstrated benefit in the more common chronic myelogenous leukemia. Interferon alfa-2 also has activity in other hematologic malignancies, including indolent non-Hodgkin's lymphomas, cutaneous T-cell lymphomas, T-cell lymphoma, and multiple myeloma, and in solid tumors such as disseminated melanoma, renal cell carcinoma, Kaposi's sarcoma, endocrine pancreatic tumors, and malignant carcinoid tumors. Interferon alfa, beta, and gamma remain under investigation to define potential roles in ovarian, breast, bladder, and cervical carcinomas and gliomas. The greatest value of the interferons will be in prolonging the disease-free interval when used in combination with other treatment modalities, including surgery, radiation, chemotherapy, and other biologic agents.

Interferons are currently the most widely used biological response modifiers. They are of high clinical value in haematological malignancies (chronic myelogenous leukaemia, multiple myeloma, non-Hodgkin lymphoma), in solid tumours (malignant melanoma, hypernephroma, pancreas neoplasms, carcinoid tumours, Kaposi's sarcoma, glioma, in ovarium, cervix and bladder carcinoma, and in basalioma) and in infectious diseases (chronic hepatitis B, chronic non-A/non-B hepatitis, chronic delta hepatitis, AIDS, Papova virus and Rhinovirus infections, leishmaniasis, leprosy) and some other conditions. Although the mechanism of action of interferons has not been explained in every detail these agents are promising therapeutic means in a number of diseases.

POEMS syndrome, a rare multisystem disease, is a variant of osteosclerotic myeloma and is characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal proteins, and skin changes. Presented herein is a case of POEMS syndrome with flushing. The flushing was intermittent, involving the face and upper third of the trunk, and was associated with hypotension and bronchospasm. Final diagnosis was made by biopsy examination of an axillary lymph node, which showed angiofollicular hyperplasia that stained strongly and selectively for lambda light chains. The patient had most of the typical features of POEMS syndrome but was unique in that her most striking finding was carcinoid-like flushing. The flushing improved with steroid therapy, as did some of the other clinical features of her disease. This case suggests that idiopathic flushing can be added to the skin changes observed in POEMS syndrome.

In the past decade, interferon, the first of a new class of biologic response modifiers, has undergone extensive Phase I and II clinical evaluation in a broad spectrum of cancers, including hematologic malignancies, lymphomas, and solid tumors. Interferon has been found to have important clinical activity in hairy-cell leukemia, low-grade non-Hodgkin's lymphoma, cutaneous T cell lymphoma, chronic myelogenous leukemia, previously untreated multiple myeloma, acquired immunodeficiency syndrome-related Kaposi's sarcoma, malignant carcinoid tumors, intravesically treated superficial bladder cancer, intraperitoneally treated ovarian carcinoma, renal cell carcinoma, and malignant melanoma. Recombinant DNA technology has produced molecules such as the interferons, which are antigenic and can induce antibody formation as part of a generalized immune response. The frequency of antibody occurrence, the magnitude of the antibody response, and the type of antibody induced by the interferons is thought to be related to several factors. These include the specific type of neoplasm for which interferon was administered; the specie of interferon administered; the dose, route, schedule, and duration of interferon administered; and the assay method and sampling time used to determine the antibody titer. Opinions and clinical observations about how these antibodies affect the clinical course of a disease vary among investigators. Some studies have demonstrated that antibody formation is associated with an abrogation of the clinical response, while others have not found any effects on the clinical course of a disease due to antibody presence.

The interferons are the first of a new class of biologic response modifiers that include, among others, the interleukins, colony-stimulating factors, erythropoietin, additional growth factors, and monoclonal antibodies. Interferons have exhibited important clinical activity in hematologic malignancies, lymphomas, and solid tumors. Specific diseases responding to interferons include hairy-cell leukemia (HCL), chronic myelogenous leukemia (CML), low-grade non-Hodgkin's lymphoma, cutaneous T-cell lymphoma, multiple myeloma, superficial bladder carcinoma, malignant carcinoid, acquired immunodeficiency syndrome (AIDS)-related Kaposi's sarcoma, ovarian carcinoma, renal cell carcinoma, and malignant melanoma. The potentially antigenic nature of the recombinant interferons can result in the formation of antibodies. These antibodies have been associated with the abrogation of some of the clinical responsiveness of some patients treated with interferons. It is hoped that the controversy existing over the role of antibody formation in treatment efficacy can be resolved by prospective trials using standardized methodology in such areas as assay type, sampling time, route of drug administration, treatment schedule, cumulative dose, and duration of treatment.

Twenty cases of metastatic neoplasms in the breast were identified in a series of 1,034 fine-needle aspirations (FNAs) of the breast, of which 389 were malignant. Patients with breast carcinomas in whom metastasis to the contralateral breast developed were excluded from this study. This series consisted of 17 women and 3 men, ranging in age from 28 to 63 years (mean, 49 years). The tumors included oat cell carcinoma (three), melanoma (three), ovarian serous carcinoma (one), bronchogenic adenocarcinoma and squamous carcinoma (four and two, respectively), lymphoma (two), carcinoid (two), transitional cell carcinoma (one), plasma cell myeloma (one), and rhabdomyosarcoma (one). In two patients, the breast mass was the first manifestation of an extramammary cancer (two adenocarcinoma of the lung). Eleven patients died of disseminated cancer shortly after the breast metastasis was diagnosed. In most cases, the aspirates displayed the cytologic features characteristic of the primary tumors, thereby establishing the metastatic nature of the neoplasm. In four cases (two carcinoids, one myeloma, and one rhabdomyosarcoma), the cytologic features were difficult to differentiate from a primary breast carcinoma; however, the final diagnosis was established by electron microscopic examination and immunocytochemical studies on the aspirates. One case (adenocarcinoma of the lung) was misdiagnosed as primary breast carcinoma on both FNA and mastectomy specimen. Because metastatic neoplasms in the breast may mimic primary breast tumors, the authors recommend the following: (1) Evaluation of FNA of breast should be done with complete knowledge of the patient's clinical history. (2) The possibility of metastasis should be suspected in lesions with unusual cytologic patterns. (3) Ancillary studies on FNA can be helpful in interpreting selected cases.

Seventeen patients with mediastinal malignant tumors (four neurogenic tumors, four thymomas, three germ cell tumors, two malignant lymphomas and one each of carcinoid, malignant melanoma, multiple myeloma and carcinoma simplex) were examined for the evaluation of percutaneous fine needle biopsy. In 16 cases of them, adequate materials for cytodiagnosis were obtained. Fifteen of the 17 cases (88%) were positive for malignant cells, and 1 case was negative. As for the histological types, 9 cytological diagnoses (60%) were compatible and 4 diagnoses (27%) were not. Regarding complications of percutaneous fine needle biopsy, 1 case of subcutaneous needle tract implantation was noted. Percutaneous fine needle biopsy is strongly recommended for diagnosis of mediastinal tumors.

A distilled water lavage is sometimes used during tumor surgery in an effort to kill tumor cells spilled into a cavity or wound. To test the efficacy of this technique, a model study utilized nine different human tumor cell lines, subjected in vitro to hypotonic exposure for 1 to 10 minutes. Only the carcinoid, multiple myeloma, leiomyosarcoma cell lines, and normal lymphocytes were destroyed by the treatment. Although breast, ovarian, gastric, bladder, and melanoma cell lines were damaged to varying degrees, viable cells persisted in all cases. These data suggest that hypotonic shock is not an effective method to kill human tumor cells.

Two human small cell lung carcinoma cell lines, NCI-H69 and NCI-H128, were used as alternating sources of immunogen to generate monoclonal antibodies to small cell lung carcinoma-associated antigens. BALB/c mice were sensitized with seven injections of live tumor cells, four with NCI-H69 cells and three with NCI-H128 cells. Somatic cell hybridization was performed by fusion of the immune murine splenocytes using syngeneic myeloma cells from the SP2/0 Ag14 cell line. Hybridoma colonies were screened against small cell lung carcinoma cells and normal lung fibroblasts with an enzyme-linked immunosorbent assay. Compared to animals immunized with only NCI-H69 or NCI-H128 cells, alternate immunization resulted in the generation of a significantly higher number of hybridomas that reacted selectively with both tumor cell lines. Monoclonal antibodies from two reactive hybrid clones generated by alternate immunization, SCLC 2051 and SCLC 5023, were uniformly negative to normal human tissues including lung, kidney, liver, spleen, breast, thyroid, brain, small intestine, and colon. While both monoclonal antibodies were nonreactive to paraffin-embedded, formalin-fixed, nonmalignant lung biopsies, the monoclonal antibody SCLC 5023 reacted with tumor cell infiltrates in biopsies from small cell lung carcinoma patients (14 of 14 cases positive), using the immunoperoxidase technique. This monoclonal reagent also reacted with other lung tumor cell types, including atypical carcinoid (5 of 5 positive), epidermoid (4 of 6 positive), undifferentiated and bronchoalveolar (3 of 4 cases each positive) carcinomas. By contrast, monoclonal antibody SCLC 2051 apparently identified an antigen expressed preferentially on small cell lung carcinoma cells (12 of 14 positive) and only rarely reacted with other lung tumor cell types (2 of 34 positive). Both monoclonal antibodies were negative to colon carcinoma, epidermoid carcinoma of the floor of the mouth, breast adenocarcinoma, and B- and T-cell leukemia and lymphoma cells, as determined by the enzyme-linked immunosorbent assay, indirect immunofluorescence, and immunoperoxidase techniques. These observations suggest that SCLC 2051 and SCLC 5023 may be of value in identifying tumor-associated antigens expressed in small cell and other lung carcinomas. In addition, the generation of antibody-producing cells towards common tumor-associated antigens may be enhanced by immunization with multiple tumor cell lines of the same histological type.
