Among 41,109 women diagnosed with breast cancer between 1935 and 1982 in Connecticut, 3,984 developed a second cancer, whereas 2,426 were expected [relative risk (RR) = 1.64; 95% CI = 1.6-1.7]. This increased risk persisted for 30 years and was highest in women under 55 years of age at the time of breast cancer diagnosis. Second primary breast cancers (RR = 3.0) accounted for almost one-half of all new neoplasms. However, if subsequent breast cancers were excluded, the risk for all other second cancers was only 1.15 (95% CI = 1.10-1.20), and no excess risk was seen among women over age 55 at initial breast cancer. Significant risks were found for cancers of the ovary (RR = 1.7) and uterine corpus (RR = 1.4), possibly linked with shared reproductive factors such as nulliparity or late age at menopause. Malignant melanoma (RR = 1.5), thyroid cancer (RR = 1.6), and colon cancer (RR = 1.2) were also significantly elevated; possible shared risk factors remain to be elucidated. Significant deficits of multiple myeloma and chronic lymphocytic leukemia were noted. Women who received initial radiotherapy compared with those who did not were at slightly higher risk of developing a second cancer, most notably acute nonlymphocytic leukemia, non-Hodgkin's lymphoma, and cancers of the esophagus, kidney, and connective tissue, although the nature of the associations was not always clear. Some of the soft tissue sarcomas were lymphangiosarcomas of the arm, a consequence of the lymphedema that may complicate radical mastectomy (Stewart-Treves syndrome). Women treated with radiation were at higher risk of developing a second breast neoplasm (RR = 3.9) than nonirradiated women (RR = 2.8). Further investigation should focus on the mechanisms underlying the relationships between breast, genital tract, and colon cancers, and on the effects of treatment modalities on the risk of subsequent neoplasms.

We have studied the incidence pattern of childhood cancers in Korea. Although the incidence of many tumors in Korea is similar to that in other countries, the incidence of acute myelogenous leukemia, non-Hodgkin's lymphoma and hepatoma is greater in Korean children. Yonsei Cancer Center commenced a study of multi-modality treatment of childhood cancers in July 1974. The most striking improvement of survival rate was seen in patients with acute lymphocytic leukemia (50% at 5 years), Wilms' tumor (65% at 5 years), neuroblastoma (45% at 2 years), osteogenic sarcoma (55% at 2 years) and malignant histiocytosis (20% at 5 years). This study is an attempt to create a basic framework providing the best possible treatment of childhood cancer in Korea. The data obtained in Korea are briefly compared with those in Japan and the United States.

Thirty-eight pretreated patients with Hodgkin's disease (HD) and malignant non-Hodgkin's lymphoma were given combination chemotherapy with VM-26, Adriamycin, bleomycin, and prednisone. Four of 15 evaluable patients with HD achieved a partial remission (PR), with a median duration of 8 months. Of 12 patients with diffuse poorly differentiated lymphocytic lymphoma, one achieved a complete remission (30+ months) and five achieved a PR (median, 6 months). One of three patients with histiocytic lymphoma had a PR of 1.5 months. There was one drug-related death. Five patients developed life-threatening hematologic toxicity. Two HD responders died of acute nonlymphocytic leukemia.

The toxic effects of high-dose busulfan (16 mg/kg) and cyclophosphamide (200 mg/kg) with autologous or syngeneic bone marrow rescue were evaluated in 19 patients (11 with acute myelocytic leukemia, one with acute lymphocytic leukemia, one with acute myelofibrosis, two with chronic myelocytic leukemia, one with Hodgkin's disease, and three with non-Hodgkin's lymphoma). Their mean age was 26 years (range, 6-50); nine patients had syngeneic and ten had autologous bone marrow rescue (six of whom had in vitro bone marrow incubation with 4-hydroperoxycyclophosphamide). Severe myelosuppression was expected and was seen in all patients; leukocyte and platelet count recovery occurred at a median of 19 days (range, 11-59) and 30 days (range, 20-89), respectively. Nausea, vomiting, and diarrhea were frequent but readily managed with vigorous medical therapy. Stomatitis was severe in 14 patients. Skin, renal, cardiac, pulmonary, and CNS complications directly attributable to drug-related toxic effects were transient and non-life-threatening. Hepatic function abnormalities were common but tended to be transient. Most patients tolerated high-dose busulfan and cyclophosphamide with manageable side effects. Hepatic veno-occlusive disease was fatal in two patients, while diffuse interstitial pneumonitis with disseminated herpes virus infection was fatal in three patients with lymphoma. All patients treated in relapse or without previous therapy had a complete tumor response. Further studies with this regimen should be pursued.

A clinical study of a new semisynthetic podophyllotoxin etoposide (NK 171) was performed in patients with various hematological malignancies refractory to standard chemotherapies. The drug was given intravenously in a dose of 100-130 mg/m2/day for five days or orally in a dose of 130-170 mg/m2/day for five days. Out of 9 patients with non-Hodgkin's lymphoma, 2 CR and 4 PR were obtained; out of 4 acute nonlymphoblastic leukemias, 1 CR, and out of 4 chronic myerogenous leukemias 2 CR and 1 PR, were obtained. The dose limiting factor was leukopenia, and alopecia was frequent while other hematologic and gastrointestinal toxicities were mild. Etoposide (NK 171) had no clinical cross resistance to other antitumor agents, thus warranting further clinical trials, in combination chemotherapy against NHL, ANLL and CML-BC.

We evaluated the occurrence of second cancers among 517 patients with non-Hodgkin's lymphoma (NHL) treated at the National Cancer Institute. Nine cases of acute nonlymphocytic leukemia (ANL) were observed compared to 0.08 cases expected (ratio of observed to expected cases, 105; 95% confidence limits, 48; 199). The excess risk of ANL was 4.1 cases per 1000 patients per year; the cumulative risk of ANL at 10 years was 7.9 +/- 3.2% (S.E.). A case-control study within the NHL cohort revealed that patients treated with both radiation and chemotherapy were at greater risk of ANL than were patients who received single-modality therapy (relative risk, 6.0; p less than 0.05), especially if the therapy included total-body or hemibody radiation. A positive correlation between cumulative radiation dose to the bone marrow and risk of ANL was demonstrated, independent of chemotherapy duration. A similar correlation between chemotherapy dose and risk of ANL was suggested but could not be proven with the available data. An apparent association between ANL risk and indolent NHL histological subtypes was due to the significantly larger amounts of potentially leukemogenic therapy to which these patients were repeatedly exposed. Only one case of ANL occurred among NHL patients whose initial therapy produced a durable complete remission. Our data are compatible with a multistep model of leukemogenesis and also underscore the need for curative NHL treatment regimens which minimize the duration and quantity of therapy required for optimum patient management.

Acute myeloid leukemia or one of its variants is being reported with increasing frequency as a second neoplasm in patients being treated for multiple myeloma, Hodgkin's disease, non-Hodgkin's lymphoma and a variety of other primary neoplasms and non-neoplastic diseases. Although many of these patients were treated with both chemotherapy and radiotherapy, many received no radiotherapy at all. Drugs most frequently implicated in the causation of acute leukemia and other second neoplasms are the alkylating agents, procarbazine and the nitrosoureas. The frequency of this syndrome varies from less than 1 per cent to 7 per cent in many reported series of patients. There could develop a reluctance to use cytotoxic agents to treat malignant neoplasms for fear of inducing acute leukemia. Although one has to consider this complication, one should not, however, withhold these drugs from a patient with a neoplasm or other potentially fatal disease in whom such therapy is the treatment of choice. We seem to be faced with the paradox that patients benefiting most from chemotherapy may be at highest risk of suffering its undesirable consequences. Although the risk of leukemogenesis or carcinogenesis in man may be small, these drugs should be used with caution in patients with indolent non-neoplastic diseases such as rheumatoid arthritis.

14 patients developed acute nonlymphocytic leukemia and 1 patient developed Burkitt's leukemia following longterm chemotherapy and/or radiotherapy for other disorders. The main primary disorders included multiple myeloma, Hodgkin's disease, non-Hodgkin's lymphoma and breast carcinoma. Acute leukemia developed earlier in patients treated by chemotherapy with or without radiotherapy than in patients treated by radiotherapy alone (63 months, range 24-132 months; 201 months, range 48 months to 30 years, respectively). 13 patients presented without organomegaly and 8 were pancytopenic. Abnormalities of myeloid and erythroid cell lines were observed in the majority of the patients. A high rate of acute erythroleukemia (5 out of 14) was found. Increased reticulin fibers were found in 3 patients. The leukemia was invariably refractory to treatment with a median survival of 4 months. The possible role of preexisting abnormal marrow structure in the development of therapy-related leukemia is discussed.

A 28-year-old man developed AML 18 months after a diagnosis of non-Hodgkin's lymphoma, diffuse small cell type, clinical stage IIA. Induction therapy for the lymphoma consisted 60Co 4000 rads bilaterally to the cervical areas and 2000 rads to the right cervical area. Complete remission was attained. Nineteen courses of combination chemotherapy with Vincristine (VCR), 6-meraptopurine (6 MP), cyclophosphamide (CY) and predonisolone (pred) was added (Total dose: VCR; 26.5 mg, 6 MP; 3320 mg, CY; 3350 mg, pred; 4310 mg). Seven days after the final chemotherapeutic treatment he developed AML with DIC. Leukemic cells were peroxidase and specific esterase (naphthol AS-D chloroacetate) positive. Induction therapy for the AML consisting of DCMP (Daunomycin, Cytosine arabinosid, 6 MP and pred) and VCR (vindesine, CY and pred) was unsuccessful. The patient died of cranial hemorrhage 3 month after the diagnosis of acute leukemia. Autopsy revealed no recurrence of non-Hodgkin's lymphoma in the lymph nodes, bone marrow, spleen and liver. Seven other cases reported in the Japanese literature are reviewed.

Eight cases of acute nonlymphocytic leukemia and one case of complicating non-Hodgkin's lymphoma were seen over a 15-year period in 408 patients treated for Hodgkin's disease (actuarial risk of acute nonlymphocytic leukemia of 4.9 percent at 12 years). Two cases of leukemia occurred 11 years after diagnosis of Hodgkin's disease. All nine complications were observed in the 220 patients who received MOPP combination therapy (9.1 percent risk of acute nonlymphocytic leukemia at 12 years) either with (n = 8) or without (n = 1) radiation therapy. Patients treated with MOPP with pathologic stage IV disease (37.2 percent risk of acute nonlymphocytic leukemia at 12 years) or over the age of 40 years (33.1 percent risk), and those with failure of MOPP treatment (18.0 percent risk) were in particular jeopardy. If MOPP treatment had been restricted to patients who were under the age of 40 years and with stages I, II, and III disease, it would have been possible to use the drug combination in two thirds of those who had been so treated while eliminating all but one case of leukemia. Furthermore, leukemia was not observed in 78 patients treated with six cycles of MOPP and less than total nodal irradiation. A final decision concerning optimal management of Hodgkin's disease will require definition of the leukemia incidence curve in the second decade after MOPP treatment, and acquisition of additional knowledge of the long-term efficacy and toxicity of alternate treatment regimens.
