Antiserum was generated in rabbits to the RPMI 8226 tissue culture line of human myeloma cells, and its reactions with fixed smears of bone marrow aspirates from patients with multiple myeloma, macroglobulinemia, benign monoclonal gammopathy (BMG), leukemia, and nonneoplastic plasmacyosis was assessed by indirect immunofluorescence. After absorption with preparations of bone marrow from normal individuals, the antiserum reacted to a significantly higher titer with a specific subpopulation of plasma cells in smears from 81% of patients having multiple myeloma and 50% of patients having BMG than with cells in smears of bone marrow aspirates from normal individuals or patients having leukemia or nonneoplastic plasmacytosis, or than with cells in smears of peripheral blood from patients having Hodgkin's and non-Hodgkin's lymphoma. Absorption of the antiserum with RPMI 8226 cells or with a bone marrow preparation from a patient with multiple myeloma but not the Jijoye line of Burkitt's lymphoma reduced reactivity for cells in myeloma bone marrow. The antiserum reacted at a lower titer with the Jijoye and EB-3 lines of Burkitt's lymphoma, the RPMI 4098 cell line of normal human lymphocytes, and culture lines of human
melanoma
and
osteogenic sarcoma
than with the RPMI 8226 cells or bone marrow from certain patients having multiple myeloma. Approximately 50% of the cells reactive with antiserum to RPMI 8226 cells in the bone marrow of patients with multiple myeloma were not producing immunoglobulin, as assessed by double immunofluorescence assay. The data suggested that a subpopulation of plasma cells in the bone marrow of patients with multiple myeloma possesses a tumor-associated antigen.

Whole lung computed tomography (CT) was performed on 25 patients with clinical diagnoses including
osteogenic sarcoma
. Ewing's sarcoma, rhabdomyosarcoma, fibrosarcoma, and
melanoma
in whom conventional tomography had revealed from one to four parenchymal nodules in one lung deemed resectable for either staging or treatment purposes. Thoracotomy was performed within 3 weeks after conventional and computed whole lung tomography. All palpable nodules were resected, measured at the time of surgery, mapped by anatomic segment, and submitted for individual histologic evaluation. CT defined more nodules than conventional tomography in 48% of cases. The additional nodules were usually pleural or subpleural and 3--6 mn in diameter. CT identified 78% of all resected nodules greater than 3 mm in diameter, compared to 59% using conventional tomography. CT was also of value in detecting bilateral nodules earlier than conventional tomography and in documenting small nodule growth on successive examination. However, 60% of the additional nodules defined by CT and resected proved to be benign granulomas and pleural-based nodes at thoracotomy.

Studies were made to determine if examination with multiple radiopharmaceuticals would improve the sensitivity and specificity of colloid liver spleen scans. Increased uptake of Ga-67 citrate and In-111 bleomycin was found in most Tc-99m sulfur colloid scan defects caused by hepatocellular hepatoma or lymphoma. Increased uptake of these agents was found in some defects caused by
malignant melanoma
, breast carcinoma and carcinoma of the lung, and was rarely seen in defects caused by cholangiocarcinoma or gastrointestinal neoplasms. Gallium was useful in the followup of patients with hepatoma. Procedures designed to evaluate the gall bladder fossa, renal impression, or blood pool activity of an apparent tumor were found to be helpful and simple to perform. Iodine-131 as NaI was useful in studying functioning liver metastases from thyroid carcinoma as were bone scanning agents in evaluating hepatic metastases from
osteogenic sarcoma
. Multiple radiopharmaceutical evaluation of the physiologic and biochemical characteristics of liver lesions supplements current radiologic examinations and increases diagnostic specificity.

Cancer chemotherapy was purely palliative until the early sixties. Tumor cures have been since obtained, first in malignant trophoblastoma and Burkitt's lymphoma, and more recently in Hodgkin's disease, diffuse histiocytic lymphoma, acute lymphocytic leukemia in children, Wilms's tumor and
osteosarcoma
. Preliminary data are suggestive of tumor cures in testicular teratomas and, possibly, in small cell carcinoma of the lung. Five patients with trophoblastoma, Hodgkin's disease,
melanoma
, chronic myelocytic leukemia and anaplastic carcinoma of the lung are briefly presented, all without evidence of tumor relapse 3 years or more after chemotherapy. Theoretical bases for improvement of the curative effect of cancer chemotherapy are discussed, including the development of new agents, and new pharmacological problems concerning drug interactions, complexes of drugs with macromolecules or immunoglobulins and liposomes are considered.

The latency period, success rate, and minimal cell inoculum size required for transplantation of continuously passaged human tumor lines into congenitally athymic (nude) mice, antilymphocyte serum (ALS)-treated congenitally athymic (nude) mice, and congenitally athymic-asplenic (lasat) mice were compared. The 11 tumor lines studied included examples of breast adenocarcinoma, transitional cell carcinoma,
osteosarcoma
, fibrosarcoma, Hodgkin's disease,
malignant melanoma
, and rhabdomyosarcoma. Of these 11 tumor lines, 3 were successfully transplanted into nude mice, compared to 5 of 10 tumor lines in ALS-treated nude mice and 9 of 11 lines in lasat mice. Moreover, the latency period was shorter and the minimal cell inoculum size was lower for lasat mice than for either nude or ALS-treated nude mice. Despite this enhancement of heterotransplantation into lasat mice and despite the growth of large local masses, no evidence of distant metastases was found.

An apparently normal, healthy 3-year-old boy developed redness of the left eye. An ophthalmologist discovered an intraocular tumor which he believed arose from the choroid. The child's 17-year-old mother developed
osteosarcoma
of the right femur during pregnancy and died a short while after his birth. Because of the rarity of
malignant melanoma
of the choroid in this age group, an exhaustive study was made resulting in firm evidence that this was probably a
melanoma
. The eye was enucleated. Pathologic study demonstrated a
malignant melanoma
with unusually pleomorphic cells.

We reviewed the records of 1,323 patients with retinoblastoma treated here between 1922 and 1978. Twenty-eight patients underwent bilateral enucleation alone and received no additional treatment for their advanced tumors. Of the 28 patients, 22 (92%) survived. Four patients were lost to follow-up, and two died of metastatic retinoblastoma. Of 22 survivors of bilateral retinoblastoma treated with enucleation alone, three developed second tumors at a mean of 15.3 years after bilateral enucleation. One patient developed a rhabdomyosarcoma in the left temple region, the second patient developed an
osteogenic sarcoma
of the right femur, and the third developed a
malignant melanoma
of the left thigh. All three patients died of their disease. The incidence of second tumors in patients who survived bilateral retinoblastoma treated without radiation was 14% (three patients), which is comparable to a series previously reported in which patients were treated with enucleation and irradiation.

In the Oncocytological Center of Zala Country were investigated in the recent years 2378 cases from effusions of pleural cavity. Ten of the tested cases had been proved to be metastases of sarcomatous lesions. Three of them were myosarcoma, two of them were
malignant melanoma
and one fibromyosarcoma, reticulosarcoma,
osteosarcoma
and sarcomatous stage of Hodgkin disease, each. The author gives a review of the cytological characteristics of metastatic sarcomatous lesions. Up to the opinion of the author there are some characteristics which can help in the typing.

In the 1970s chemotherapy has been successfully incorporated into curative primary treatment programs for various adult malignancies so that it is no longer solely palliative treatment for advanced disease. For at least three malignancies and tentatively a fourth (breast and colon carcinoma,
osteosarcoma
, and
melanoma
), certain groups of patients have had longer disease-free survival produced by the use of chemotherapy after surgical removal of the primary lesion. The potential impact on cancer mortality from these treatment results is obvious. We review here the fundamental laboratory concepts that have led to human trial of multimodal primary therapy regimens. Data from numerous clinical trials are analyzed, with delineation of the problems encountered in the interpretation of their results.

1,4-Dihydroxy-5,8-bis(((2[(2-hydroxyethyl)amino]ethyl)amino))-9,-10-anthracenedione dihydrochloride (CL 232315; NSC 301739D), a representative of a new chemical class of compounds with antineoplastic properties, has been evaluated for antitumor activity in experimental mouse tumor systems. The compound produced significant increases in life span (ILS) and long-term survivors when tested against the P388 and L1210 leukemias as well as the solid neoplasms, B16
melanoma
and Colon Tumor 26. The optimal treatment regimens resulted in a 173 to greater than 200% ILS with 20 to 80% 60-day survivors in mice with P388 leukemia, A 205% ILS with 55% 60-day survivors in mice with L1210 leukemia, and an ILS of greater than 300% with 80% 90-day survivors in mice with B16
melanoma
. In contrast to Adriamycin, CL 232315 was active against the i.v. implanted L1210 leukemia and demonstrated moderate activity against P388/Adria, a subline of P388 resistant to Adriamycin. The compound was ineffective when tested against the Lewis lung carcinoma and the Ridgway
osteogenic sarcoma
. CL 232315 was active i.p., s.c., and i.v., but p.o. activity was not demonstrated. Schedule dependency was not observed when the compound was administered once daily for nine days, once every four days, or as a single dose.
