Of 602 patients treated for non-Hodgkin's lymphomas, 9 developed overt acute nonlymphocytic leukemia or preleukemia with refractory cytopenia and cytogenetic abnormalities of the bone marrow. A Kaplan-Meier estimate of the cumulative probability of leukemic complications was 6.3 +/- 2.6% (mean +/- SE) 7 years after start of treatment. All 9 patients with leukemic complications belong to a major subgroup of 498 patients treated with alkylating agents, predominantly cyclophosphamide. The risk of leukemic complications in this subgroup was compared with the risk in 312 patients treated with other alkylating agents for Hodgkin's disease, and with the risk in 553 patients treated with dihydroxybusulfan for ovarian carcinoma. Cumulative 9-year risks were 8.0 +/- 3.3%, 12.8 +/- 3.5%, and 7.1 +/- 1.9%, respectively. The general risk of secondary leukemia after long-term treatment with alkylating agents ranges from 1% to 1.5% per year from 2 to at least 9 years after start of treatment.

Three types of interferon preparation (alpha, beta and gamma) have been used in the treatment of tumours in vivo. At the time of writing no information is available on IFN-gamma treatment of tumour patients. Treatments with IFN-alpha and IFN-beta have been undertaken at many clinical centres. Both types of preparation can exert side effects. Both types have also been able to cause regression of certain tumours in individual patients. At our hospital, IFN-alpha has been given to tumour patients over the last decade. Antitumour effects have been registered on patients with juvenile laryngeal papillomatosis, Hodgkin's disease, myelomatosis, ovarian carcinoma, hypernephroma and glioblastoma. Further study is needed on how therapy with IFN should best be undertaken and also how such treatment compares with other treatments of various tumour diseases. IFN therapy should also be combined with other such treatments.

Rosenberg et al discovered in the coordination complexes of platinum a new, novel type of potential antitumor agent. Cisplatin [cis-dichlorodiammine platinum (II)4 proved active against a variety of rodent tumors and acted synergistically when combined with other chemotherapeutic agents. Initial clinical tests by Hill et al in 1971, showed cisplatin to be active against malignant lymphoma, Hodgkin's disease, and certain other malignancies. Significant nephrotoxicity, nausea, and vomiting were noted. Since then, cisplatin has been tested alone and in combination chemotherapy and has proven an efficacious anticancer agent in squamous cell carcinoma of head and neck, ovarian carcinoma, disseminated testicular cancer, and others. Its therapeutic value was acknowledged when approved in 1978 by the U.S. FDA for treatment of the latter cancer. The current clinical literature indicates clearly that the full potential of this drug has not yet been realized. Hydration and diuresis have served to mitigate much of the nephrotoxicity, while significant strides toward amelioration of the nausea and vomiting have also been achieved. Literally, thousands of chemically-related congeners have been synthesized, and many have shown marked potency against rodent tumors. Very few, however, have been evaluated clinically, vis-a-vis malonato trans(-)-1,2-diaminocyclohexane platinum(II); this appears a most promising and fertile area of future investigation.

A phase II study of vindesine in 41 evaluable patients demonstrated the drug to be active in heavily pretreated patients with breast cancer, non-Hodgkin's lymphoma, and other tumors. There were two partial responses in 11 patients with breast cancer (18%) and five partial responses and one complete response in 11 patients with non-Hodgkin's lymphoma (40%). Other responses were seen in small cell carcinoma of the lung, ovarian carcinoma, and Hodgkin's disease. Prior vinca exposure did not adversely affect the response rate. Neutropenia was dose-limiting. Neurotoxic effects occurred in 10% of the patients. A high incidence of local tissue reactions at the injection site (27%) could be reduced by a careful administration technique. Vindesine should be studied further in combination with other agents.

Recombinant granulocyte colony-stimulating factor (rhG-CSF) has been shown to hasten granulocyte recovery after autologous BMT. In current protocols, rhG-CSF treatment starts 1 day after BM reinfusion. Our study retrospectively examined the effects on haematological recovery of a day 6 delayed administration. Seventy-eight patients receiving autologous BMT for malignant lymphoma (21 non-Hodgkin's lymphoma and 9 Hodgkin's disease) or solid tumors (33 breast carcinoma and 5 ovarian carcinoma) were split up into three study groups. Two groups receiving a 5 micrograms/kg/day of rhG-CSF starting either 1 day (day +1 group, n = 25 patients) or 6 days (day +6 group, n = 24 patients) after BM reinfusion were compared with 29 historical control patients. Granulocyte recovery to 0.5 x 10(9)/l was 12 days in day +6 and day +1 groups versus 16 days in control group (p < 0.005) without any difference in other hematological parameters, infectious complications or length of hospitalisation between the three groups. The day +6 administration allows elimination of a median of 7 days rhG-CSF. It has been concluded that the day +6 administration gives the same clinical benefit as day +1 administration with consequent cost reductions.

Renal function was prospectively analysed in 26 patients treated with radiotherapy for various types of malignancies. In patients with gastric non-Hodgkin's lymphoma stage I-II (gNHL, n = 5), the 99mTc-diethylene-triamine-penta-acetic acid (99mTc-DTPA) renal uptake and the relative 99mTc-dimercapto-succinyl acid (99mTc-DMSA) accumulation decreased gradually and concomitantly in the high-dose, whole-volume irradiated left kidney (40 Gy/5, 5 weeks), down to 25 +/- 10% (mean +/- 1 S.E.M.) and 31 +/- 11%, respectively, after 6-9 years. The absolute 99mTc-DMSA uptake in the left kidney declined down to 33 +/- 12% whereas in the low-dose, whole-volume irradiated right kidney (12-13 Gy/3 weeks) it increased up to 187 +/- 11%. When considering renal volume changes with single photon emission computed tomography, the left kidney in the gNHL patients was reduced to 30 +/- 13%, with, surprisingly, a contralateral enlargement up to only 119 +/- 7% (P < 0.05). The overall renal function in this group of patients, as assessed by creatinine clearance and by [125I]iothalamate/[131I]hippuran clearance was reduced to 48-68%. In the Hodgkin's disease patients (HD, n = 7) given 40 Gy in 4 weeks to 30-50% of the left kidney, the 99mTc-DTPA filtration and the relative 99mTc-DMSA uptake in the left kidney was reduced to 75 +/- 4% and 81 +/- 3%, respectively. The absolute 99mTc-DMSA changes were 78 +/- 10% and 135 +/- 13%, respectively. No significant renal functional alterations were observed in patients with either ovarian carcinoma (n = 7) or seminoma (n = 7). These data suggest a significant, compensatory response of the non-irradiated or low-dose irradiated kidney which, however, appears to be incomplete after contralateral, whole-volume, high-dose irradiation. Such compensatory response might be overestimated when considering only relative or absolute changes in radioactivity uptake.

Radiolabeled monoclonal antibodies (MAbs), by virtue of their tumor specificity, offer the prospect of localized, highly targeted radiation treatment of malignant tumors. To date, a large number of radioimmunotherapy (RIT) studies have been reported in experimental and clinical settings showing the potential of this therapeutic strategy. This includes RIT-trials in hepatoma, cholangiocarcinoma, ovarian carcinoma, brain tumors, melanoma, neuroblastoma and especially Hodgkin's and non-Hodgkin's lymphomas. Despite very promising results in some of these studies, radioimmunotherapy is currently still in a developmental status. Selective accumulation of MAbs at tumor sites-a prerequisite for effective radioimmunotherapy-is a complex process. Many factors such as antigen heterogeneity, distinct antibody features (affinity, subclass, fragment size, etc.), labeling techniques, tumor physiology and competing antigens were identified in the last years using theoretical and experimental tumor models. Strategies to improve these critical parameters are currently under investigation in order to increase the efficacy of radioimmunotherapy.

Normal cells show a limited lifespan in culture and the phenotype of cellular senescence. Tumors and tumor cell lines have typically overcome this form of growth suppression and grow continuously as immortal cell lines in culture. We have exploited the DNA virus SV40 to study the mechanism by which human fibroblasts overcome senescence and become immortal. Multiple steps have now been identified, including inactivation of cellular growth suppressors through direct interaction with SV40 large T antigen and through mutation of a gene on chromosome 6 (designated SEN6). In this study, we sublocalize the site of SEN6 to 6q26-27 based on molecular genetic analysis. Twelve SV40-immortalized fibroblast cell lines share a deletion in this area based on assessment for loss of heterozygostiy (LOH) for seven informative markers on 6q. Two immortal cell lines (AR5 and HALneo) appeared to have retained separate single copies of chromosome 6 despite the fact that they are both derived from the same preimmortal SV40-transformant and should share the same mutated allele of SEN6 (Hubbard-Smith et al., 1992). Detailed analysis by polymerase chain reaction, restriction fragment length polymorphism and fluorescence in situ hybridization shows, however, that although they differ for 17 markers from the centromere to 6q26, they share AR5 derived sequences (eight markers) distal to 6q26 including the minimal deletion region, further supporting the assignment of SEN6 to this region. Since human tumors including non-Hodgkins lymphoma, mammary carcinoma and ovarian carcinoma show LOH in 6q26-27, inactivation of SEN6 may be responsible for immortalization of these tumors as well.

We have identified three unbalanced translocations involving chromosomes 5 and 17, der(5)t(5;17), der(17)t(5;17), and dic(5;17), in the malignant cells from 17 patients with myeloid neoplasms. Six patients had a primary myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) de novo; ten patients had therapy-related MDS and/or AML (t-MDS/t-AML), and one patient had chronic myelogenous leukemia in myeloid blast phase. Two of the six patients with MDS or AML de novo had extensive exposure to industrial solvents, and one patient had Seckel syndrome. The primary diagnoses for the ten patients with t-MDS/t-AML were breast carcinoma and Hodgkin's disease in two patients each, and non-Hodgkin's lymphoma, multiple myeloma, chronic lymphocytic leukemia, ovarian carcinoma, thyroid carcinoma, and rhabdomyosarcoma in one patient each. Four patients had received both prior chemotherapy and radiotherapy, four others received prior chemotherapy only, and the remaining two patients only prior radiotherapy. Fluorescence in situ hybridization of centromere-specific probes for chromosomes 5 and 17 revealed that a dicentric rearrangement was the most common (13/16 patients examined). The genetic consequences of these chromosomal rearrangements are partial monosomy for 5q and 17p. Two of six patients examined had point mutations in TP53, suggesting that loss of function of TP53 in addition to loss of a tumor suppressor gene on 5q may be involved in the pathogenesis of the malignant disease in some of these patients.

We conducted a population-based study to determine the contribution of germline mutations in known candidate genes to ovarian cancer diagnosed at age <30 years. Women with epithelial ovarian cancer were identified through cancer registries. DNA samples were analyzed for mutations in BRCA1, the "ovarian cancer-cluster region" (nucleotides 3139-7069) of BRCA2, and the mismatch-repair genes hMSH2 and hMLH1. Probable germline mutations in hMLH1 were identified in 2 (2%; 95% confidence interval 1%-8%) of 101 women with invasive ovarian cancer diagnosed at age <30 years. No germline mutations were identified in any of the other genes analyzed. There were no striking pedigrees suggestive of families with either breast/ovarian cancer or hereditary nonpolyposis colorectal cancer (HNPCC). There was a significantly increased incidence of all cancers in first-degree relatives of women with invasive disease (relative risk [RR] = 1.6, P=.01) but not in second-degree relatives or in relatives of women with borderline cases. First-degree relatives of women with invasive disease had increased risks of ovarian cancer (RR = 4.8, P=.03), myeloma (RR = 10, P=.01), and non-Hodgkin lymphoma (RR = 7, P=.004). Germline mutations in BRCA1, BRCA2, msh2, and mlh1 contribute to only a minority of cases of early-onset epithelial ovarian cancer. Our data suggest that early-onset ovarian cancer is not associated with a greatly increased risk of cancer in close relatives.
