We determined O6-alkylguanine-DNA alkyltransferase (AGT) activity in the peripheral blood lymphocytes (PBLs) of normal controls and patients with Hodgkin's disease or non-Hodgkin's lymphoma and compared these values with those of Epstein-Barr virus (EBV)-transformed cell lines prepared from the same PBL samples. PBLs have an AGT level characteristic of the individual from whom the cells were obtained. The AGT activity of lymphoblastoid cell lines obtained from a control group of PBLs was significantly correlated with the activity of the PBLs from which they were derived (r = 0.742). There was no significant correlation between PBLs and EBV-transformed lines derived from these PBLs in Hodgkin's disease/non-Hodgkin's lymphoma patients (r = 0.407, -0.225, and 0.270 for patients prior to, during, or after therapy, respectively). The lack of significant correlation between lines and PBLs was not due to random fluctuations in AGT activity, because multiple lines prepared from the same PBL sample were found to be highly correlated in AGT activity. In order to account for these results, we suppose that PBLs from a given individual are a heterogeneous population with respect to AGT activity. In normal individuals, the AGT activity of early passages of the multi-clonal EBV-transformed cell lines reflect the AGT activity of the PBLs from which they were derived. Malignancy and/or treatment with chemotherapeutic agents may selectively affect those lymphocytes which are targets for EBV-transformation so that the resultant cell line is no longer representative (with respect to AGT activity) of the total PBL population. Long-term culture of lymphoblastoid cell lines results in changes in AGT activity in some but not all cell lines suggesting that with time in culture, subsets with different AGT activities may be selected. There appears to be no growth advantage of low AGT activity and only rarely have we obtained lines with no measurable AGT activity, even after long periods in culture.

The prognostic significance of the DNA Malignancy Grade (DNA-MG) was tested for 83 malignant non Hodgkin lymphoma patients in comparison with three different subjective morphological classification systems (New Working Formulation for Clinical Usage, Rappaport and Kiel Classification). Monolayer smears prepared from paraffin embedded tissue and imprint smears from fresh cut lymph-nodes were investigated. Feulgen staining was performed automatically. The scalar DNA-MG was determined by rapid interactive DNA-cytometry, using an automatic microscope and a TV-image analysis system. A strong influence of the DNA-MG on length of survival was found. Compared with morphological classification systems, the DNA-MG was of greater prognostic validity as revealed by different statistical tests. Significant differences of survival probabilities between some groups with differences of 0.5 DNA-MG only were found. The interobserver reproducibility of this new prognostic index was found to be 95% within a range of +/-0.4 DNA-MG.

The mortality experience of 5,406 men (cohort I) employed at one aluminum smelter on Jan. 1, 1950, and 485 men employed at a second plant (cohort II) on Jan. 1, 1951, is reported. For each man, the total number of years of exposure to tars, the number of years since first exposure to tars, and an index of exposure to tars expressed in tar-years were calculated. More than 99% of the men in the first cohort and 98% of the men in the second cohort were traced. Of the 1,539 men in cohort I who were deceased as of December 31, 1977, death certificates were obtained for 1,432 (93%). Of the 92 men in cohort II who were deceased as of December 31, 1977, death certificates were obtained for 80 (87%). The results showed that men in cohort I died of the following causes at approximately the same rate as or less frequently than men of similar age in the Province of Quebec: tuberculosis; circulatory disease; hypertensive heart disease; trauma; leukemia and aleukemia; and malignant neoplasms of the pancreas, genital organs, brain, intestine, and rectum and other abdominal areas. There were no deaths from pneumoconiosis or Alzheimer's disease. Although the observed and expected numbers of deaths in some of the cause-of-death categories were small, men in cohort I died of the following causes more frequently than did men of similar age in the Province of Quebec: respiratory disease; pneumonia and bronchitis; malignant neoplasms (all sites); malignant neoplasms of the stomach and esophagus, bladder, and lung; other malignant neoplasms; Hodgkin's disease; and other hypertensive disease. Mortality from malignant neoplasms of the bladder and lung was meaningfully related to numbers of tar-years and of years of exposure. Exposure-response relationships were less clear for malignant neoplasms of the esophagus and stomach and for other malignancies. Mortality from respiratory disease for men with 21 or more tar-years of exposure was approximately twice that of persons never exposed to tars. The apparent excess of other hypertensive disease was restricted to men never exposed to tars. Malignant neoplasm of the lung was the only cause of death in cohort II that was in excess of that expected at Quebec provincial rates.

The first National AIDS Malignancy Conference was held sixteen years after the first outbreak of Kaposi's sarcoma (KS) was noted in the medical press. The conference was devoted to the spectrum of malignancies that occur with AIDS. Researchers were divided on whether KS is tumorigenic or not. Other controversial topics included the use of standard-dose chemotherapy in patients with late-stage HIV infection, screening and aggressive treatments used for precancerous cervical changes, the management of AIDS-related malignancies in patients who are responding well to HIV treatments, and whether some AIDS-related malignancies will be classified as AIDS-defining conditions. The Centers for Disease Control and Prevention (CDC) currently considers KS, lymphoma, and cervical cancer as AIDS-defining malignancies. Specific sections of the conference dealt with pediatric cancers, squamous cell carcinoma, testicular cancer, lung cancer, and Hodgkin's disease.

Malignancy is the most common cause of tracheoesophageal fistulas. The malignancies commonly implicated in the development of tracheoesophageal fistulas are primary bronchial or esophageal carcinomas. Hodgkins disease rarely leads to such a fistula. We report a case of Hodgkin's disease with a tracheoesophageal fistula as well as a left recurrent nerve palsy at presentation. This presentation has no precedent in literature. The patient was treated with systemic chemotherapy and involved field radiotherapy. On follow up 1 year after the completion of treatment, he was clinically and radiologically disease free.

The prognosis for higher risk childhood B-cell non-Hodgkin lymphoma has improved over the past 20 years but the optimal intensity of treatment has yet to be determined. Children 21 years old or younger with newly diagnosed B-cell non-Hodgkin lymphoma/B-cell acute lymphoblastic leukemia (B-NHL/B-ALL) with higher risk factors (bone marrow [BM] with or without CNS involvement) were randomized to standard intensity French-American-British/Lymphoma Malignancy B (FAB/LMB) therapy or reduced intensity (reduced cytarabine plus etoposide and deletion of 3 maintenance courses M2, M3, M4). All patients with CNS disease had additional high-dose methotrexate (8 g/m2) plus extra intrathecal therapy. Fifty-one percent had BM involvement, 20% had CNS involvement, and 29% had BM and CNS involvement. One hundred ninety patients were randomized. The probabilities of 4-year event-free survival (EFS) and survival (S) were 79% +/- 2.7% and 82% +/- 2.6%, respectively. In patients in remission after 3 cycles who were randomized to standard versus reduced-intensity therapy, the 4-year EFS after randomization was 90% +/- 3.1% versus 80% +/- 4.2% (one-sided P = .064) and S was 93% +/- 2.7% versus 83% +/- 4.0% (one-sided P = .032). Patients with either combined BM/CNS disease at diagnosis or poor response to cyclophosphamide, Oncovin [vincristine], prednisone (COP) reduction therapy had a significantly inferior EFS and S (P < .001). Standard-intensity FAB/LMB therapy is recommended for children with high-risk B-NHL (B-ALL with or without CNS involvement).

Bone marrow necrosis is a rare cause of bone marrow failure. Malignancy is the most frequent cause of bone marrow necrosis. Among malignancies, non-Hodgkin lymphoma (NHL) accounts for 10% of cases of bone marrow necrosis. Virtually all reported cases of NHL-associated bone marrow necrosis have developed in immunocompetent hosts. We report on a case of bone marrow necrosis complicating post-transplant lymphoproliferative disorder (PTLD) and resolving after rituximab monotherapy. This case report provides the first evidence of (i) bone marrow necrosis as a complication of PTLD; (ii) rapid resolution of NHL-associated bone marrow necrosis after rituximab treatment.

Intensive chemotherapy for human immunodeficiency virus (HIV)-associated non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) has resulted in durable remissions in a substantial proportion of patients. High-dose chemotherapy and autologous stem cell transplantation (AuSCT), moreover, has resulted in sustained complete remissions in selected patients with recurrent chemosensitive disease. Based on a favorable experience with dose-reduced high-dose busulfan, cyclophosphamide, and AuSCT for older patients with non-HIV-associated aggressive lymphomas, an AIDS Malignancy Consortium multicenter trial was undertaken using the same dose-reduced busulfan and cyclophosphamide preparative regimen with AuSCT for recurrent HIV-associated NHL and HL. Of the 27 patients in the study, 20 received an AuSCT. The median time to achievement of an absolute neutrophil count (ANC) of >or= 0.5 x 10(9)/L was 11 days (range, 9-16 days). The median time to achievement of an unsupported platelet count of >or= 20 x 10(9)/L was 13 days (range, 6-57 days). One patient died on day +33 posttransplantation from hepatic veno-occlusive disease (VOD) and multiorgan failure. No other fatal regimen-related toxicity occurred. Ten of 19 patients (53%) were in complete remission at the time of their day +100 post-AuSCT evaluation. Of the 20 patients, 10 were alive and event-free at a median of 23 weeks post-AuSCT. Median overall survival (OS) was not reached by 13 of the 20 patients alive at the time of last follow-up. This multi-institutional trial demonstrates that a regimen of dose-reduced high-dose busulfan, cyclophosphamide, and AuSCT is well tolerated and is associated with favorable disease-free survival (DFS) and OS probabilities for selected patients with HIV-associated NHL and HL.

Venous thrombosis (VT) is a rare condition in childhood, being usually associated with congenital predisposition or acquired risk factors. The incidence of VT among children with cancer is between 1 and 36%. The highest incidence is among children with acute lymphoblastic leukaemia, followed by those with lymphoma and solid tumours. Malignancy and/or chemotherapy complications are considered as triggering factors. We report a case of a 15-year-old girl with non-Hodgkin lymphoma who developed generalized seizures during chemotherapy. Head computed tomography revealed right transverse and sagittal sinus thrombosis. Anticoagulation treatment using heparin as well as thrombolytic treatment with recombinant human tissue plasminogen activator (rhtPA) were introduced. The immediate application of rhtPA resulted in recanalisation of initially involved vessels which led to recovery with no neurological deficits. The reported case of severe venous thrombosis suggests that systemic treatment with rhtPA is effective and safe in children with cerebral venous sinus thrombosis.

No comparative studies exist for relapsed/refractory (rel/rfr) acquired immune deficiency syndrome (AIDS)-related lymphoma (ARL). To determine practices over the last decade and to assess the outcomes of salvage chemotherapy with curative intent and autologous stem cell transplant (ASCT), we retrospectively evaluated treatment outcomes in patients with rel/rfr ARL who were treated in 13 national AIDS Malignancy Consortium (AMC) sites between 1999 and 2008 (n = 88). The most commonly used second-line therapies were ICE (ifosfamide/carboplatin/etoposide, n = 34), dose adjusted EPOCH (etoposide/prednisone/vincristine/cyclophosphamide/doxorubicin, n = 17) and ESHAP (etoposide/methylprednisolone/cytarabine/cisplatin, n = 11). The odds of achieving a response were lower for those with non-Hodgkin lymphoma (NHL) than for those with HL and for those with primary refractory disease than for those with relapse. Overall survival (OS) was significantly longer for those with relapsed disease compared to those with refractory disease and for those with non-Burkitt NHL compared to those with Burkitt. OS was longer in patients who underwent ASCT compared to those who did not (1-year OS: 63.2% vs. 37.2%). However, among 32 patients (36%) who achieved a complete or partial response (CR/PR) after second-line therapy, 1-year OS was not different between the two groups (87.5% for ASCT vs. 81.8% for non-ASCT). Long-term survival in some patients with rel/rfr ARL may be possible without transplant, although transplant remains the standard of care for chemotherapy sensitive disease.
