Bone marrow autotransplantation involves the administration of very high doses of chemotherapy or radiation therapy, or both, followed by infusion of autologous hematopoietic stem cells. This treatment was used in the past as a salvage therapy for patients with end-stage cancers. Occasional cures in patients with chemotherapy-responsive malignancies encouraged oncologists to utilize this treatment earlier when a better result might be achieved. This has led to a substantial number of long-term disease-free survivors in non-Hodgkin's lymphoma, Hodgkin's disease, acute leukemia, and neuroblastoma. Studies are currently ongoing in the treatment of breast cancer, multiple myeloma, testicular cancer, and ovarian cancer. Important areas for future investigation include the identification of optimal criteria for patient selection and timing of the therapy, the need for infusion of hematopoietic stem cells as cloned hematopoietic growth factors become available, the identification of the most effective high-dose regimens, and the need for "purging" tumor cells from the marrow before re-infusion. Successfully addressing these issues will increasingly require large comparative trials.

The occurrence of treatment-related hematologic malignancies after adjuvant therapy with alkylating agents for gastrointestinal cancers, ovarian carcinoma, and breast cancer and after treatment for Hodgkin's disease, non-Hodgkin's lymphoma, germ-cell tumors, and multiple myeloma has been well documented. Adjuvant chemotherapy is frequently used for the treatment of early stage breast cancer, and to date there has been no increase in the incidence of secondary myelodysplastic syndromes or acute leukemia after cyclophosphamide-based regimens when compared with surgical controls. This report describes two patients who developed acute myelocytic leukemia only after exposure to cyclophosphamide, methotrexate, and 5-fluorouracil adjuvant therapy. These two cases of acute leukemia, which developed 3 years after diagnosis of breast cancer and initiation of chemotherapy, were characterized by trilineage dysplasia and pancytopenia, and had abnormalities of chromosomes 5 and 7: characteristics consistent with treatment-related leukemia. Many women are diagnosed with early stage breast cancer each year who are potential candidates for adjuvant therapy. Although certain subgroups of patients have been shown to benefit from adjuvant therapy, continued efforts must be directed at identifying responders so that others will not be exposed to the additional risks of chemotherapy.

Splenic erythropoiesis was demonstrated by surface counting of 59Fe in 129 of 1,350 ferrokinetic studies performed over a 15 year period. These 129 studies were carried out in 108 patients, including 40 with chronic myelogenous leukemia (CML), 24 with agnogenic myeloid metaplasia (AMM), 18 with polycythemia vera (PV), six with a myelodysplastic syndrome, five with acute leukemia, three with prostate or breast carcinoma, two each with aplastic anemia or Hodgkin's disease, and one each with idiopathic thrombocythemia, multiple myeloma, chronic renal failure, or treated hypopituitarism. Splenomegaly was present in 83% of the studies and hepatomegaly in 72%. Grade II-III myelofibrosis was demonstrated in 62% of the cases. Hepatic erythropoiesis was present in 77% of the studies (only 38% in PV), and marrow erythropoiesis was undetectable in 33%. Total erythropoiesis was about twice normal (range 0.2 to 8 times normal) but was ineffective to varying degrees in 86% of the studies. Relationships between organomegaly, myelofibrosis, and extramedullary erythropoiesis, as well as differences among clinical disorders, are discussed. Differences observed between CML in chronic or blastic phase suggested that the erythroid cell line was involved in the proliferative process. It is concluded that splenic erythropoiesis 1) is encountered in a variety of clinical conditions; 2) is not necessarily associated with splenomegaly or myelofibrosis, even in the myeloproliferative disorders; 3) is part of a predominantly extramedullary (in the liver as well as in the spleen), expanded, and largely inefficient total erythropoiesis; and 4) can be evaluated in a semiquantitative manner by surface counting.

We studied the height growth of 96 children presenting with acute leukemia or non Hodgkin lymphoma, together with an investigation of GH and TSH in 41 of them. There were 2 groups: group I consisting of 19 patients without brain irradiation and group II consisting of 77 patients with prophylactic brain irradiation. Initial average height was identical in both groups. Growth rate was significantly decreased in group II but not in group I (p less than 0.01). There is a correlation between the decrease of growth rate and the decrease of GH to arginine stimulation test (p less than 0.03). A lack of response to GRF-44 was noted in 4 of 11 investigated patients. TSH and prolactin secretions were unchanged.

Simultaneous involvement of bands 8p11 and 16p13 in a primary, even though rare, chromosomal translocation recently described in acute nonlymphocytic leukemia may be of crucial interest in some subtypes of this acute leukemia, particularly in the monocytic form. In the present report we describe this translocation in acute nonlymphoblastic leukemia FAB M4, possibly secondary to Hodgkin's disease, though it is also possible that the leukemia may have developed de novo. The aberration t(8;16)(p11;p13) was present in 100% of direct and cultured bone marrow cell preparations. A very high frequency of cells with nonclonal structural chromosome aberrations was also observed in peripheral blood cultures (more than 53%). Random translocations and deletions constituted most of the observed alterations. These findings are discussed with regard to the relationships between secondary leukemias and intensive polychemotherapeutic treatments of primary neoplasias.

This paper presents an update from the Late Effects Study Group on 292 cases of second malignant neoplasms (SMN) occurring in individuals who were diagnosed with their first neoplasm in childhood. Data are presented regarding the types of first and second neoplasm, the therapy administered, and the predisposing factors. Of the 292 cases (308 SMN), the most common primary was retinoblastoma followed by Hodgkin's disease, soft-tissue sarcomas, and Wilms' tumor. This is not similar to the relative frequency of these cancers in children but rather reflects specific risk factors. Bone sarcomas were the most common SMN among the 208 SMN developing in previously irradiated sites while acute leukemia was the most common SMN unassociated with radiation. Known predisposing conditions to cancer were present in 73 cases; retinoblastoma was the most common of these, followed by neurofibromatosis. There were ten patients with three and three patients with four malignant neoplasms. In 14 patients, the cause of SMN was not suggested by known risk factors as these patients had negative family histories and received no radiation or chemotherapy. We note, therefore, that although most cases of SMN in survivors of childhood cancer can be attributed to radiation, genetic disease, chemotherapy, or combinations of these, unrecognized predisposition or chance may also play a role.

Epirubicin (4'-epidoxorubicin) is an antineoplastic agent derived from doxorubicin. The compounds differ in the configuration of the hydroxyl group at the 4' position. Epirubicin, like doxorubicin, exerts its antitumor effects by interference with the synthesis and function of DNA and is most active during the S phase of the cell cycle. Epirubicin is administered by intravenous (IV) injection. It is metabolized by the liver and primarily eliminated in the bile. About 10% of the drug is eliminated in the urine. Dosage adjustments are recommended for patients with liver metastases or elevated liver function tests. The elimination half-life of epirubicin is 30 to 40 hours. Clinical studies indicate activity in breast cancer, non-Hodgkin's lymphomas, ovarian cancer, soft-tissue sarcomas, and pancreatic cancer. There is also evidence of activity against gastric cancer, small-cell lung cancer, and acute leukemia. Epirubicin has limited activity as a single agent against head and neck tumors or non-small-cell lung cancer, but may be beneficial in combination with other agents. The overall activity of epirubicin appears to be comparable with that of doxorubicin. However, more studies are needed to define its role in combination chemotherapeutic regimens. The acute dose-limiting toxicity of epirubicin is myelosuppression. Nausea, vomiting, and alopecia are also common. Epirubicin may cause transient cardiac arrhythmias and alterations of the electrocardiogram. Chronic therapy is limited, but available data indicate that epirubicin can be administered in higher cumulative doses than doxorubicin before cardiotoxicity limits further therapy.

The goal of this review is to provide a readable and exhaustive reference in three major areas of geriatric oncology: complications of chemotherapy and radiotherapy, responsiveness of cancer to systemic treatment, social issues in the care of elderly patients with terminal illnesses. The conclusions of this study are: 1. Progressive deterioration of renal function is the most consistent change of aging. Adjustment of doses of renally excreted drugs to individual creatinine clearance may prevent life-threatening myelotoxicity in the elderly. 2. Intensive chemotherapy regimens (acute leukemia, non Hodgkin's lymphoma) cause more serious and prolonged myelotoxicity in the elderly. Elderly are more susceptible than younger patients to cardiotoxicity and central and peripheral neurotoxicity. Age is a poor predictor of complications in other organs or systems. 3. The prognosis of patients with Hodgkin's disease worsens with aging, possibly due to increased prevalence of mixed cellularity histology. It is controversial whether the prognosis of other neoplasias is poorer. Prognosis is not age-related in multiple myeloma. In general, elderly in good performance status may benefit from systemic cancer treatment to the same extent as younger patients, except for Hodgkin's disease. 4. The Informal Support Network, epitomized by the family, appears the most suitable environment to care for the elderly with cancer.

Many patients with Hodgkin's disease, acute leukemia, non-Hodgkin's lymphoma, testicular cancer, and other tumors now regularly achieve sustained clinical remissions and cures. Drugs used in the treatment of cancer have profound and often lasting effects on the testis and ovary. Germ cell production and endocrine function may both be altered with the magnitude of the effect related to the age, pubertal status, and menstrual status of the patient as well as to the particular drug, dosage, or combination administered. The primary testicular lesion caused by all antitumor agents studied thus far is depletion of the germinal epithelium lining the seminiferous tubules. Combination chemotherapy regimens that include alkylating agents produce germinal aplasia and permanent infertility in the majority of patients. The risk of ovarian injury following combination chemotherapy is clearly related to the age of the patient at the time of treatment. Overall, 40 to 50% of women treated with combination chemotherapy become amenorrheic, although the frequency of amenorrhea in women older than 35 years may be as high as 90%. Interventions to protect the gonads from the effects of chemotherapy have not yet been developed; thus, male patients should be offered an opportunity to store semen prior to treatment and all patients should be counseled concerning the potential gonadal toxicity of cancer chemotherapy.

Autologous bone marrow reinfusion rapidly repopulates severely damaged bone marrow thus shortening the period of myelosuppression following high-dose chemotherapy programs. This strategy has been successfully employed in several hematologic malignancies such as acute leukemia, Hodgkin's disease, non-Hodgkin's lymphoma, and chronic myelogenous leukemia. More recently a number of clinical trials have investigated the role of high-dose chemotherapy with autologous bone marrow transplant in solid tumors. This strategy, when used in patients with advanced refractory metastatic breast cancer, results in a high objective response rate (30-70%) but most of these remissions are of short duration (3-4 months). When using high-dose single agents complete remissions are rare; with combination chemotherapy they are more frequent (20-50%). The utilization of high-dose chemotherapy with autologous marrow transplant as a consolidation after achieving a partial or complete remission with standard chemotherapy has shown more promising results with complete remissions approaching 70% in some series. The impact of any of these strategies on overall survival of patients with metastatic breast cancer remains to be demonstrated. The optimal patient selection criteria and strategies for additional development of this field are discussed.
