32P is effective therapy for polycythemia and primary thrombocytosis. The Polycythemia Vera Study Group is comparing radioactive phosphorus with alkylating agents to determine relative efficacy. Less well investigated is the effectiveness of 32P vs. busulfan in chronic granulocytic leukemia. Endolymphatic administration of radiopharmaceuticals may play a role in the therapy of infradiaphragmatic lymphoma. Among the radionuclides that have at times been used in hematology are 32P, 198Au 24Na, 76As, 89Sr, 52Mb, 54Mn, 91Y, 95Zr, 95Cb, 111Ag, 109Pd, 131I, 185W, and 192Ir. As stated, 32P has proven single most efficacious agent. The hematologic diseases that have been treated include both malignant and benign conditions. Among the malignant conditions are polycythemia vera, agnogenic myeloid metaplasia, thrombocythemia, leukemia, Hodgkin's disease, and multiple myeloma. Hemophilia, and Osler--Weber--Rendu disease are among the benign entities in which the agents have been tried. Polycythemia and thrombocythemia remain those in which the greatest success has been achieved.

Present knowledge of the HL-A system as it relates to lymphoproliferative disease is reviewed briefly. Preliminary results from a current study demonstrate an elevated frequency of Aw33 and depressed frequency of B17 associated with non-Hodgkin's lymphoma-leukemia. In somewhat weaker association, Aw24 and Aw33 are elevated in follicular-center-cell lymphomas, while Bw44 is depressed. It is concluded that more specific subclassification of the lymphomas according to immunologic concepts may aid in correlating the disease with HL-A type as it has for Hodgkin's disease.

In vitro production of interferon by blood leukocytes from patients with lymphosarcoma, lymphogranulomatosis, leukemia, cancer tumours, pneumonia, as well as by leukocytes of mice with Rauscher leukemia, and mice in the condition of hyporeactivity to interferon inducer was studied. Alongside with quantitative differences in interferon production, biological differences in the properties of interferons produced of normal and sick humans and animals were revealed. The biological differences consist in that the interferon produced by leukocytes from cancer and leukemia patients interacting with homologous cell culture is conducive to more rapid formation of resistance to the indicator virus than the interferon produced by normal leukocytes. Thus, resistance of the homologous cell culture to the infection with the indicator vesicular stomatitis virus developed within 1--2 hours after contact with leukocyte interferon from patients and only within 5--6 hours after contact with that of normal subjects. This finding is not specific for cancer and leukemia, as the same was observed with specimens from patients with pneumonia and from mice hyporeactive to interferon inducer. It is suggested that patients with cancer and leukemia have a state of interferon hyporeactivity.

Malignant cells from 49 children with lymphoid neoplasms other than Hodgkin disease were evaluated by surface marker and morphologic studies. We classified the patients into three groups: 36 patients (74%) with acute lymphocytic leukemia; 7 (14%) classified as convoluted lymphocytic lymphoma/leukemia; and 6 (12%) with small noncleaved follicular center cell lymphoma/leukemia. Diffuse marrow involvement was present at diagnosis in some patients in the latter two groups, but their clinical course was not characteristic of the patients with acute lymphocytic leukemia. Male predominance, poor prognosis, and high incidence of central nervous system disease characterized patients in the convoluted lymphocytic and follicular center cell lymphoma/leukemia groups. Clinical presentation in these two groups differed. Proliferations of convoluted lymphocytes were associated with mediastinal masses and proliferations of follicular center cells with intraabdominal tumors. The high incidence of CNS disease in children with neoplasms of convoluted lymphocytes and follicular center cells suggests that these processes have a predilection for the CNS and that patients with them may benefit from CNS prophylaxis.

The value of splenectomy is assessed from diagnostic and therapeutic viewpoints in a series of 80 patients with various syndromes marked by hypersplenia. In the congestive type of splenomegaly, splenectomy resulted in complete normalization of the blood picture in all cases but one, and in primary splenic congestion it even proved curative in the majority of the cases. In leukaemia, non-Hodgkin's lymphomas, in myelofibrosis, and first of all in immuncytopenia, splenectomy was also of benefit, and had generally a palliative effect in non-autoimmune hypersplenia as well. In non-haematological syndromes associated with hypersplenia, namely, splenic tuberculosis, Boeck's sarcoid, SLE, haemorchromatosis and splenic vein thrombosis, splenectomy had generally a palliative, and combined with other therapeutic measures, a curative effect, depending on the primary disease. In a number of patients with hypersplenia associated with splenomegaly, it was only with the aid of splenectomy that the primary disease could be diagnosed.

The histopathologic studies of 103 patients under 16-years old with Hodgkin's disease including 5 cases who had staging laparotomy during the last 10 years were reviewed. The following conclusions were drawn: 1. No significant sex differences among subtypes were noted. 2. Associated glomerulopathy, nephrotic syndromes, and amyloidosis were occasionally found. 3. In childhood, lymphomas excluding leukemia are the most frequent malignancies. Among the lymphomas, Hodgkin's disease predominates. 4. The most frequent subtype both in the original biopsy and after staging laparatomy was mixed cellularity. The nodular sclerosis type was the rarest. The subtypes generally did not change during the subsequent biopsies and in laparotomy done up to 6 months later. 5. Lymphomas were most frequently noted in cervical area. Males are affected more severely than females. The peak incidence was around 8 years. A brief review and discussion on the comparison of data from other countries are also given.

Unilateral tonsillar enlargement may result from infection, chronic inflammatory response, or neoplasm. Neoplasms that commonly produce a unilaterally enlarged tonsil include lymphomas (lymphocytic and histiocytic types) and squamous cell carcinomas. Rarer tumors include extramedullary plasmacytomas, Hodgkin's disease, leukemia, and metastatic neoplasms. Sixteen cases of unilateral tonsillar enlargement owing to causes other than squamous cell carcinoma are reviewed. When examining a patient with unilateral tonsillar enlargement, diagnosis of a neoplastic disease must be considered.

In recent literature numerous papers have been published concerning the accuracy of scintigraphic detection of liver metastases. Unfortunately however, the problem of false positive results is not particularly discussed in these papers. Because of the lack of information it was our aim to compare our own scintigraphic results with postmortem histopathological findings. Our investigations were carried out in 139 patients with various types of malignancy. Included in the investigations were 20 patients with primary liver tumor. The interval between scintigraphic examination and the histological verification ranged from 3 days to 1 year. In 62 of the patients with liver metastases, histopathology revealed liver metastases, while 77 patients showed no liver involvement. We arrived at the correct diagnosis "liver metastasis" in 50 out of 62 patients (80.6%). False negative scintigrams (19.4%) were found in most of the respective cases when diffuse malignant involvement such as leukemia and Hodgkin's disease was present, and also when the size of the metastases was less than 2 cm in diameter. Fifty six out of 77 patients (72.7%) without histopathological evidence of liver metastases revealed negative scintigrams. Twenty one (27.3%) false positive scintigrams were mostly due to (diffuse) nonmalignant disease e.g. fibrosis and cirrhosis. The overall accuracy of liver scintigraphy in our study was 76.2%. In 18 of 20 (90%) patients with focal liver disease correct diagnosis was established. 7 patients with benign liver tumors and 11 of 13 patients with hepatocellular carcinoma showed focal defects. Considering the fact that liver scintigraphy is a non-invasive procedure, it can be recommended as screening method. In connection with sonography and computer tomography liver scintigraphy can undoubtedly improve the diagnostic accuracy in detecting liver metastases and primary liver tumors.

Of 13 cancers that tend to occur at lower rates in aboriginal Americans or in the native lands of Japanese, Chinese, and Spanish-speaking persons than in United States whites, rates for all but one (laryngeal) have increased in migrants to the United States. In addition to leukemia, these 13 cancers include neoplasms that have been related, at least in part, to a diet high in animal fats or proteins (colon and rectum cancer); reproductive and endocrinologic factors and a diet high in animal fats or protein (prostate, ovary, corpus uteri, breast, and testis cancer); chemical carcinogens (lung, larynx, bladder, and pancreas cancer); and a common infectious agent that, like polio viruses, causes clinically overt disease with a frequency directly related to age of patient at initial infection (Hodgkin's disease). Of 9 cancers that occur at higher rates in aboriginal Americans or in one or more of the native lands of migrants than in United States whites, the rates of 5 tend to decrease in migrants. These include cancers that may be related to food preservation (stomach cancer); products of microorganisms that may contaminate foods (esophagus and liver cancer); and infectious agents (nasopharynx, cervix uteri, and liver cancer). In addition, rates of cancer of the thyroid are high in aboriginal Americans; those of the gallbladder are high in individuals of native American ancestry and in Japanese; incidence of salivary gland tumors is high in Alaskan natives and Colombians; and rates of kidney cancer are high in Alaskan natives. Five types of epidemiologic studies are described that should be conducted in the migrants and in their countries of origin and adoption to elucidate further the etiology of various neoplasms.

Medical observations of leukemia or Hodgkin's disease clusters in time and space have led statisticians to invent techniques to evaluate the probability that these occurrences were due to chance. A difficult computation in human genetics was simplified by a matrix devised by a non-genetical statistician, and readily adapted to newly emerging computer-processing. The experiences exemplify the special opportunity in Japan to enhance research by merging mathematical talent with biomedical observations.
