One patient with acute nonlymphocytic leukemia (ANLL) in remission was given intensive chemotherapy (DAT regimen) as late intensification treatment. Seven leukaphereses were performed during the period of marrow recovery following aplasia induced by the DAT regimen. High numbers of nucleated cells (7.8 X 10(8)/kg) and granulocyte-macrophage precursors (9.5 X 10(4)/kg) were collected and then cryopreserved and stored in liquid nitrogen. When he relapsed, the patient was treated with etoposide (600 mg/m2), cyclophosphamide (120 mg/kg), and total body irradiation (1000 rad), followed by the transfusion of thawed autologous leukocytes. The time to reach 0.5 X 10(9) granulocytes/liter and 50 X 10(9) platelets/liter was 16 and 35 days, respectively. This observation demonstrates that circulating hemopoietic stem cells are capable of complete hemopoietic reconstitution after marrow-ablative therapy with supralethal doses of chemoradiotherapy.

Alkylating agents have caused acute nonlymphocytic leukemia (ANLL), probably bladder cancer, and possibly other solid tumors. Phenacetin also has enhanced risk of bladder cancer, and probably also carcinoma of the renal pelvis. Topical nitrogen mustard, potassium arsenite, tar ointments, and methoxsalene have been related to development of nonmelanotic skin cancers. Immunosuppression by azathioprine, usually with prednisone, has enhanced risks of non-Hodgkin's lymphomas, hepatobiliary cancers, and various mesenchymal tumors. Liver cancers have been reported in users of androgenic anabolic steroids, and both hepatic cell adenomas and carcinomas have been associated with use of combined oral contraceptives. These contraceptives reduce risks of endometrial and ovarian carcinomas. Estrogens increase risk of endometrial cancer. Exposure to diethylstilbestrol in utero can result in clear cell carcinomas of the vagina and cervix, and possibly testicular carcinomas.

A simple, rapid and effective technique using the IBM (Cobe)-2991 cell processor for the concentration of buffy coat cells from large volume marrow has been well adopted (n = 16). Only about one-eighth of the original volume was obtained while retaining more than 90% of the total nucleated cells to be cryopreserved in polyolefine bags with TC-199 culture medium and final 10% dimethylsulfoxide (DMSO) (n = 9), processed by a computerized Nicool ST-20 (France) programmed freezer and stored in a vapor phase of liquid nitrogen at -196 degrees C. Stem cell assay by CFU-GM after thawing yielded a mean of 50.39 +/- 19.54% which has been satisfactory for clinical implementation. So far, three cases with hematological malignancies had been rescued by autologous cryopreserved marrow after supralethal doses of chemoradiotherapy. Two patients with acute nonlymphocytic leukemia transplanted in 1st remission as of Oct. 31 had been disease free for 178+ and 157+ days, respectively, after transplant which was taken at the corresponding age of 53 and 42 years. The other patient who was a victim of Hodgkin's disease, stage IV, and was transplanted in 3rd remission, expired on the 59th day because of the complication of idiopathic interstitial pneumonitis despite excellent granulocytopoietic reconstitution. The preliminary results are encouraging for further exploitation, especially for those who would otherwise be candidates for allogeneic bone marrow transplantation but are limited by age or lack of an HLA-identical sibling to serve as marrow donors.

Children undergoing ABMT, a procedure which entails massive doses of chemotherapy along with total-body irradiation, are candidate to develop severe gastrointestinal toxicity and prolonged anorexia requiring administration of Parenteral Nutrition (PN) for variable periods. We report a series of 35 consecutive children affected by malignancies who underwent 37 courses of PN after ablative therapy followed by ABMT. Age ranged from 8 months to 17 years; 16 were females, 19 males. There were 23 cases of neuroblastoma, 5 of Wilms' tumor, 3 of acute myelogenous leukemia, 2 of Ewing's sarcoma, 1 case each of rhabdomyosarcoma and acute lymphoblastic leukemia. All patients developed severe neutropenia for 9-42 days (median 18 d). Fever occurred in all patients; sepsis was documented in 10. Duration of PN ranged from 10 to 64 days (23 +/- 9; mean +/- SD). PN solution, containing crystalline L-Aminoacids (8.5%) mixed with 33% glucose, minerals, trace elements and vitamins provided for children a caloric intake of 49.8 +/- 17.3 Kcal/Kg/day with a nitrogen intake of 0.26 +/- 0.27 g/Kg/day. Nutritional assessment, utilizing percent ideal body weight, serum protein electrophoresis, C3, pseudocholinesterase and fibrinogen, was performed at the beginning and at the completion of each course of PN. Mean percent ideal body weight was 95.8 before PN, 98.5 on last day of PN (p less than 0.0005). Other parameters did not change significantly. No metabolic complication nor severe electrolyte imbalance were observed except for 5 patients who developed hypokalemia in coincidence with administration of Amphotericin B.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty-eight patients with advanced Hodgkin disease were treated with a combination of cyclophosphamide, vinblastine, procarbazine, and prednisone (CVPP) from 1970 to 1973 and followed prospectively. Long-term results after a median follow-up of 14 years are reported. Seventeen of the 28 complete responders (61%) survived more than 10 years from the initiation of chemotherapy. At the current time, 12 of the 28 patients (43%) are continuously disease-free 12.8 to 15.3 years after completing induction chemotherapy. Two additional patients are alive in third and fifth remissions. All relapses occurred within 5.5 years of completing induction chemotherapy. Late complications included sterility, aseptic osteonecrosis, severe pulmonary fibrosis, and chronic uveitis. Four of the complete responders (14%) developed second neoplasms, including acute myelogenous leukemia, non-Hodgkin lymphoma and small cell carcinoma of the lung. All second malignancies were fatal and developed 5-13 years after initiation of induction chemotherapy. Our data confirm that cure is possible with alternative regimens to MOPP (nitrogen mustard, vincristine, procarbazine, and prednisone).

From 20 patients with solid tumors or acute nonlymphocytic leukemia in remission, hemopoietic progenitor cells were taken and stored in liquid nitrogen, for use in autologous bone marrow transplantation. Bone marrow aspiration resulted in a volume of 920(+/- 170) ml containing 16.8(+/-6.0) x 10(9) nucleated bone marrow cells and 7.2(+/-4.4) x 10(6) myeloid progenitor cells (CFUc). With use of the Haemonetics blood cell separator a progenitor cell-enriched fraction is obtained. This fraction is depleted of 90(+/-6)% of the erythrocytes and 59(+/-15)% of the neutrophils contained in the original. The original aspirate volume is reduced to one-fifth (21 +/- 3%) while containing 88(+/-38)% of the original CFUc's and 52(+/-11)% of the nucleated bone marrow cells. This technique of bone marrow enrichment has the advantage of a minimum of open-air contact, being independent of extensive laboratory facilities and manpower. The enriched fraction is frozen in autologous plasma and a final concentration of 10% (v/v) DMSO, using a program-controlled freezer (L'Air Liquide). Materials are stored at liquid nitrogen temperature in bags (Gambro) and test vials. Total CFUc recovery in test vials after thawing was 81(+/-32)%.

The Southwest Oncology Group (SWOG) performed a randomized study (SWOG 7518, CAR 2) of chemotherapy using ten courses of nitrogen mustard, vincristine, procarbazine, and prednisone (MOPP) plus low-dose bleomycin (LDB), versus three courses of combined therapy, MOPP + LDB plus radiotherapy (XRT) from October, 1974, to April 1980, in pathologic stage III Hodgkin's disease. The present report includes data on 136 registered patients, of whom 112 are fully or partially evaluable. At this preliminary analysis, complete remission rates are 82% for chemotherapy alone and 82% for combined treatment. There are no statistically significant differences in survival or relapse-free survival between the two treatment programs, and no specific trends for stage IIIA versus IIIB. The estimated 3-year survival rate for all patients was 82%. Toxicities are comparable when considering the highest grades. There was one case of acute myeloblastic leukemia on combined treatment. Preliminary evidence suggests that patients with nodular sclerosis histologic type are more likely to relapse on chemotherapy alone than on combined treatment.

Two cases of secondary acute nonlymphocytic leukemia developing after combined chemo-radiotherapy for Hodgkin's disease (HD) are reported. The first case was a 28-year-old woman with PSIIIsA HD, treated with total lymphoid irradiation followed by combination chemotherapy that was almost entirely ABVD (Adriamycin, bleomycin, vinblastine, dacarbazine), who developed acute monoblastic leukemia three years after the diagnosis of Hodgkin's disease. We believe this to be the first reported case of secondary leukemia associated with the combination of radiotherapy and ABVD chemotherapy. The second case was a 37-year-old man with Stage IVB Hodgkin's disease, treated with radiotherapy and MOPP (nitrogen mustard, vincristine, procarbazine, prednisone) who developed acute myeloblastic leukemia five years after the diagnosis of Hodgkin's disease. Both cases showed typical changes of panmyelosis demonstrated by cytochemical and ultrastructural studies. In both cases, bone marrow cells had a dominant clone with a markedly abnormal karyotype. The nature of therapy-related secondary leukemia after Hodgkin's disease and its relationship to current modes of treatment are discussed.

Of 209 Hodgkin's disease patients treated at least 6 months with a five-drug combination of induction chemotherapy and having a complete remission, four patients developed acute myelogenous leukemia (AML) as a second malignant neoplasm. The overall relative risk for development of AML is 185.0 (P less than 0.05) and the mean time to occurrence of AML is 5.3 years (median, 5.25 years). When examining patient subgroups, the highest relative risk noted was 338.5 (P less than 0.05) for that group of patients receiving an additional 6 months of postinduction MOPP (nitrogen mustard, vincristine, procarbazine, and prednisone). Patients receiving only 6 months of induction BVCPP (BCNU, vinblastine, cyclophosphamide, procarbazine, and prednisone) had a relative risk of 166.2 (P less than 0.05). These data results are consistent with previous reports that patients treated for Hodgkin's disease are at high risk for development of AML. However, to date, no patients in this series have developed second malignancies other than AML.

Eighteen patients referred to The Johns Hopkins Oncology Center for treatment of acute myelocytic leukemia during a 2-year period had pretreatment wbc counts greater than 50,000/microliter. Despite immediate admission, aggressive supportive care, and rapid institution of chemotherapy, six patients died from complications of the high wbc count at presentation. The patients who died had significantly higher initial wbc counts, lower platelet counts, and lower arterial oxygen saturation; they were older, more likely to be female, and more likely to have abnormal serum urea nitrogen than the 12 patients who survived. Five of the six patients who died had experienced a delay of greater than 48 hours from diagnosis to referral, and only one of the 12 patients who survived was not promptly referred for treatment at the time of diagnosis (P = 0.004). A mathematical model, the logit of the fraction of the initial wbc count versus the logarithm of time after starting therapy, was used to describe the response of the wbc count to chemotherapy. This logit analysis reduced the data for individual patients to a linear function, permitting statistical description of the population as a whole. This statistical description makes possible the comparison of different approaches to lowering the wbc count in such patients and the correlation of rate of response of wbc count with the probability of achieving remission and with duration of remission.
