Seven patients with multiple myeloma who developed a second neoplasm are presented. There were four patients with acute leukemia and three patients with non-hematologic neoplasms. The patients with acute leukemia were among the longest survivors (median duration approximately 72 months) and the response to anti-leukemic therapy in these patients was generally poor. Of the three patients with non=hematologic neoplasms, one patient was observed with simultaneous renal cell carcinoma and the other two patients developed adenocarcinoma of the colon and lung subsequently. In addition, two patients with mammary carcinoma who subsequently developed multiple myeloma were included. Literature was reviewed and the possibility that multiple myeloma itself might be a risk factor for the development of other malignancies was discussed.

A sixty-eight-year-old male was found to have renal carcinoma after seven months of constitutional symptoms. Initial study of the patient showed a puzzling array of laboratory abnormalities. These led initially to a search for gastrointestinal malignancy and then later to consideration of multiple myeloma. This case serves as a reminder of the propensity of early renal carcinoma to produce striking constitutional symptoms and marked hematologic and serum protein abnormalities. These may occur in the absence of metastases and are frequently reversible as shown in this case with resection of the primary lesion.

Plasmacytoma, a localized extramedullary mass of plasma cells, is one manifestation of multiple myeloma. Renal plasmacytomas are rare lesions with neovascularity on arteriogram. This may cause confusion with the much more common renal cell carcinoma unless the clinician is aware of this entity. A case is presented, the literature reviewed, and problems in management discussed.

Virtually any malignancy may lead to hypercalcemia, but carcinoma of the breast, myeloma, and carcinoma of the lung are especially frequent offenders. A more difficult diagnostic problem is posed by the "silent" tumor which secretes a substance causing hypercalcemia. Foremost in this category are bronchogenic carcimona and hypernephroma.

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 proteins with antiviral, antiproliferative, and immune-regulating activity. They are classified as alfa, beta, or gamma on the basis of antigenicity and biologic properties. Alfa interferons as single-agent therapy produce clinical improvement in approximately 90 percent of patients with hairy-cell leukemia, and up to 70 percent of patients with chronic myelogenous leukemia (CML) in early-stage disease. Prolonged suppression or elimination of the leukemic cell clone by interferon may ultimately increase survival of patients with CML. Interferon is not effective single-agent therapy for multiple myeloma, but improves response rate when combined with conventional agents. AIDS-associated Kaposi's sarcoma demonstrates a 40 percent objective response rate to interferon, with less risk of immune system suppression than conventional cytotoxics. Other applications of alfa interferon include malignant melanoma and renal cell carcinoma. Beta interferon is similar to the alfa subtype and may have utility in treatment of brain tumors. Gamma interferon is an important immune regulator with qualitative and quantitative differences in its efficacy and toxicity when compared with alfa interferon.

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.

We report on a patient with metastatic renal adenocarcinoma that had been detected following evaluation for monoclonal gammopathy associated with osteolytic lesions. When the foregoing associated conditions present, we must discard the presence of a myeloma. No objective data relating gammopathy with tumor behaviour are currently available.

The sternum is known as a common site of bone metastasis in a variety of neoplasms. Sternal metastasis is usually visualized as hot spot on bone scintigraphy. However, photon deficiency in the sternum on bone scintigraphy is reported in few cases with malignancy. We undertook a retrospective analysis to clarify the clinical significance of photon deficiency in the sternum in 12 patients with malignancy. Twelve patients (five breast cancer, two multiple myeloma, one lung cancer, one renal cell cancer, one hepatocellular carcinoma, one malignant lymphoma, and one thyroid cancer) showing cold sternal metastasis on bone scintigraphy were identified among 9,430 patients in whom bone scintigraphy was performed. Except for two cases with pathologically confirmed sternal metastasis, all patients showed lytic change in the sternum on tomography or CT scan. Six cases of solitary sternal metastasis showed partial effect of systemic therapy (chemotherapy, humoral therapy, and radiation therapy) and surgical treatment. It is necessary to keep in mind that this type of lesion may occur as a manifestation of metastatic disease.

Hypercalcemia is one of the most serious metabolic disorders associated with cancer. The incidence and clinical circumstances associated with hypercalcemia vary in different types of cancer. Hypercalcemia is the most frequent metabolic complication of breast cancer and is usually related to widespread osteolytic metastases; however, local and systemic humoral factors mediating bone resorption have been described. In some patients with breast cancer, hypercalcemia results from treatment with estrogens, antiestrogens, androgens, or progestins. Coexisting primary hyperparathyroidism rarely confounds the diagnosis. In patients with lung cancer, the incidence of hypercalcemia varies with histology and is often unrelated to bone metastases. Hypercalcemia may occur either late or early in the disease but is seldom a presenting symptom. In patients with cancers of the head and neck region, hypercalcemia is most often associated with advanced recurrent and terminal disease, presumably humorally mediated. In renal cell carcinoma, hypercalcemia is also an adverse prognostic indicator, commonly mediated by humoral factors. On the other hand, almost all patients with multiple myeloma have extensive osteolytic bone destruction and hypercalcemia is frequently a presenting symptom. Hypercalcemia is uncommon in most lymphomas; however, it is usually a prominent feature of adult T-cell lymphomas and also occurs in some large cell, diffuse B-cell lymphomas. Awareness of the setting in which hypercalcemia of malignancy occurs will lead to its prompt diagnosis and institution of appropriate therapy.
