A pilot investigation on impact of participation in a long-term follow-up clinic (LTFU) on breast cancer and cardiovascular screening among women who received chest radiation for Hodgkin lymphoma.

BACKGROUND: Women treated with chest radiation for Hodgkin lymphoma (HL) are at significantly increased risk of breast cancer and cardiovascular disease. HL survivors are recommended to have annual dual screening with mammogram (MMG) and breast magnetic resonance imaging (MRI). They are also recommended to undergo echocardiogram (echo) 5 years after completion of radiation. We performed a pilot study to characterize the women who are and are not receiving proper dual screening for breast cancer and baseline echo, and to examine the impact of a LTFU clinic consultation on screening. METHODS: A retrospective chart review of 114 women treated for HL at University of Minnesota (UMN) between 1993 and 2009 was performed. Demographics, disease and treatment history (age at diagnosis, stage, radiation dose and field, chemotherapy, recurrence) were assessed, as well as screening practices (MMG, MRI, both and echo), participation in LTFU clinic, and recommendations from providers. Data was summated in yes/no (y/n) format; statistical analysis was performed using chi-squared and Fisher's exact tests. Breast cancer and cardiovascular screening outcomes were compared by participation in the LTFU clinic (y/n) using Fisher's exact tests. P values < 0.05 were considered statistically significant. RESULTS: Forty-one of 114 women met inclusion criteria and had follow-up data for analysis. Median age at diagnosis was 29 years; 67.6% were diagnosed at stage IIa. Median dose of radiation was 3570 cGy. 56.1% participated in the LTFU clinic at the UMN. 36.6% had dual screening with both MMG and MRI, 41.5% had screening with only MMG, and 19.5% had no screening performed. Women were more likely to have dual screening if they were seen in LTFU clinic vs not seen in LTFU clinic (52.2 vs 16.7%, p = 0.02). 67.5% of women were screened with echo; women were also more likely to have screening with echo if seen in LTFU clinic vs not seen (86.4 vs 44.4%, p = 0.007). CONCLUSION: Many women are not getting the proper dual screening for breast cancer despite their increased risk, with only 36.6% of our study sample getting dual screening. Having a consultation in a LTFU clinic increases dual screening for breast cancer and echo screening for cardiovascular disease. Proper screening allows for detection of secondary breast cancer at earlier stages where treatment can be local therapy. Diagnosing CV disease early could allow for proper preventative treatment or intervention.

Post-transplant lymphoproliferative disorders in lung transplant recipients: 20-yr experience at the University of Minnesota.

Post-transplant lymphoproliferative disorders (PTLD) are potentially fatal complications of solid organ transplantation. The natural history of PTLD varies considerably among the different types of organs transplanted. While lung transplant recipients are highly susceptible to PTLD, there are only a few small studies that detail PTLD in this setting. We undertook this study to better describe the characteristics and treatment response in PTLD after lung transplantation. We conducted a retrospective chart review of lung and heart/lung-transplant recipients between 1985 and 2008. A total of 32 cases (5%) of PTLD were identified in 639 patients. The median interval after transplantation to the diagnosis was 40 (3-242) months. Eight patients (25%) were diagnosed within one yr of transplantation and had PTLD predominantly within the thorax and allograft. Twenty-four patients (75%) were diagnosed more than one yr after transplantation and their tumors mainly affected the gastrointestinal tract. Monomorphic PTLD, diffuse large B-cell lymphoma, was diagnosed in 91%. Treatment of PTLD varied according to stage and clinical circumstances. Twenty-four patients (75%) have died. The median overall survival was 10 (0-108) months. PTLD after lung transplantation remains a challenge as a result of its frequency, complexity and disappointing outcome.

Recombinant interferon-alpha2b added to oral cyclophosphamide either as induction or maintenance in treatment-naive follicular lymphoma: final analysis of CALGB 8691.

Recombinant interferon alpha-2b (IFN-alpha2) has direct and indirect antiproliferative effects in lymphoma, and may augment cytotoxicity when combined with chemotherapy. CALGB 8691 is a randomized study of daily oral cyclophosphamide (CPA) at 100 mg/m2 with or without IFN-alpha2 at 2 x 106 IU/m2 three times per week, followed by a second randomization between IFN-alpha2 maintenance (2 x 106 IU/m2 three times weekly) versus observation in treatment-naïve patients with follicular lymphoma (FL). Five hundred eighty-one patients were randomized to either CPA (n = 293) or CPA plus IFN-alpha2 (n = 288). One hundred five responding patients were randomized to observation and 99 to maintenance IFN-alpha2. With a median follow-up of 11.5 years, the median event-free and overall survival (OS) for CPA induction alone were 2.5 years (95% CI 2.2, 3.0) and 9 years (95% CI 7.7, 10.2), compared to 2.4 years (95% CI 2.1, 3.1) and 8.4 years (95% CI 7.5, 11.1) for the combination arm (p = NS). Patients with a partial response (PR) and randomized to observation had the worst outcome (event-free survival (EFS) 1.8 years versus 3.9 years; p = 0.002). Patients with a PR randomized to IFN-alpha2 had a similar EFS to compared to patients with complete response (CR), but this did not translate into a survival advantage. Myelosuppression was increased in IFN-alpha2-containing arms. Despite the small benefit in EFS in patients with PR randomized to IFN-alpha2 maintenance, we conclude that the addition of low dose IFN-alpha2 did not significantly improve the response rate, duration of response, event-free, or OS obtained with single-agent daily oral CPA in patients with previously untreated FL.

Prognostic factors in follicular lymphoma: a single institution study.

Recently developed prognostic models for follicular lymphoma have proven useful in predicting overall survival (OS), but most have used data from multiple centers. Our goal was to look at prognostic factors within a single institution. We conducted a retrospective study on 77 newly diagnosed patients with follicular lymphoma, focussing on clinical characteristics, symptom duration before diagnosis, pathologic findings, including grade, laboratory data, imaging studies at initial presentation and management. The study population was 53% male. Ages ranged from 25 to 87 years (median 51). By Ann Arbor classification 4% were stage I, 8% stage II, 18% stage III and 69% stage IV. Initial therapy was deferred in 39%. The remaining patients received stage-appropriate therapy. Survival was measured from time of diagnosis to death. Prognostic factors at initial diagnosis that were statistically significant in univariate log-rank comparisons of Kaplan-Meier survival curves were used to build a multi-variate proportional hazard regression model of OS. Median OS for these patients was 10.3 years. OS differed only with high (>12 g/dl) versus low (<12 g/dl) hemoglobin (p=0.001) and in younger (<60 years) versus older (>60 years) patients (p=0.05), as indicated by univariate log-rank tests. Both hemoglobin and age were also significant in a multivariate proportional hazards analysis. Low hemoglobin and increased age were independent predictors of lower OS with hazard ratios of 6.6 (95% CI, 2.2-20.1) and 3.7 (95% CI, 1.2-11.7), respectively. Median survival for older patients who also had anemia was only 3.1 years. A test for interaction between age and hemoglobin was negative (p=0.35). The estimated hazard ratio for an older individual with low hemoglobin was 24.7 (95% CI, 4.0-153.3). To assess the proportional hazards assumption we tested for an interaction between time and both age (p=0.92) and hemoglobin (p=0.66) and found no evidence against proportionality. A hemoglobin <12 g/dl and age >60 years at diagnosis are significant predictors of worse OS.

Phase III randomized intergroup trial of subtotal lymphoid irradiation versus doxorubicin, vinblastine, and subtotal lymphoid irradiation for stage IA to IIA Hodgkin's disease.

PURPOSE: The management of early-stage Hodgkin's disease in the United States is controversial. To evaluate whether staging laparotomy could be safely avoided in early-stage Hodgkin's disease and whether chemotherapy should be a part of the treatment of nonlaparotomy staged patients, a phase III intergroup trial was performed. PATIENTS AND METHODS: Three hundred forty-eight patients with clinical stage IA to IIA supradiaphragmatic Hodgkin's disease were randomized without staging laparotomy to treatment with either subtotal lymphoid irradiation (STLI) or combined-modality therapy (CMT) consisting of three cycles of doxorubicin and vinblastine followed by STLI. RESULTS: The study was closed at the second, planned, interim analysis because of a markedly superior failure-free survival (FFS) rate for patients on the CMT arm (94%) compared with the STLI arm (81%). With a median follow-up of 3.3 years, 10 patients have experienced relapse or died on the chemoradiotherapy arm, compared with 34 on the radiotherapy arm (P <.001). Few deaths have occurred on either arm (three deaths on CMT and seven deaths on STLI). Treatment was well tolerated, with only one death on each arm attributed to treatment. CONCLUSION: These results demonstrate that it is possible to obtain a high FFS rate in a large group of stage IA to IIA patients without performing staging laparotomy and that three cycles of chemotherapy plus STLI provide a superior FFS compared with STLI alone. Extended follow-up is necessary to assess freedom from second relapse, overall survival, late toxicities, patterns of treatment failure, and quality of life.

Brief-duration high-intensity chemotherapy for patients with small noncleaved-cell lymphoma or FAB L3 acute lymphocytic leukemia: results of cancer and leukemia group B study 9251.

PURPOSE: To define the activity and feasibility of brief-duration high-intensity chemotherapy for adults with small noncleaved, non-Hodgkin's lymphoma (SNC) and the L3 variant of acute lymphocytic leukemia (L3 ALL). PATIENTS AND METHODS: Seventy-five adults with either SNC or L3 ALL (median age, 44 years) were treated with an aggressive regimen that consisted of one cycle of cyclophosphamide and prednisone followed by cycles containing either ifosfamide or cyclophosphamide; high-dose methotrexate, vincristine, dexamethasone, and either doxorubicin or etoposide/cytarabine; or intrathecal triple therapy with prophylactic CNS irradiation. RESULTS: All 24 patients with L3 ALL and the 30 of 51 patients with SNC confirmed by central histologic review were included in this analysis. Forty-three of 54 patients achieved complete response (CR) (18 of 24 with ALL and 25 of 30 with SNC), and 28 are alive and in continuous CR with a median follow-up of 5.1 years. Hematologic toxicity was profound, and nonhematologic toxicity was notable, with 10 of 75 patients treated developing significant neurologic toxicity consisting of transverse myelitis in five patients, CNS toxicity in three, and severe peripheral neuropathy in two. All patients who did not achieve CR died of the disease, and all recurrences occurred within 16 months of the end of treatment. Responses and toxicities were similar in the patients with both lymphoma and leukemia. CONCLUSION: Aggressively delivered chemotherapy is potentially curative in as many as half of patients with SNC and the L3 ALL variant. This treatment regimen had considerable neurologic toxicity and has been modified.

Dose-escalated cyclophosphamide, doxorubicin, vincristine, prednisone, and etoposide (CHOPE) chemotherapy for patients with diffuse lymphoma: Cancer and Leukemia Group B studies 8852 and 8854.

BACKGROUND: To address the feasibility and outcome of moderate dose intensification with granulocyte-colony stimulating factor (G-CSF) for patients with aggressive non-Hodgkin lymphoma (NHL), the Cancer and Leukemia Group B (CALGB) conducted two studies evaluating dose-escalated cyclophosphamide and etoposide in the cyclophosphamide, doxorubicin, vincristine, prednisone, etoposide (CHOPE) regimen. METHODS: Eligibility criteria included histologically documented, diffuse small cleaved, diffuse mixed, diffuse large cell, or immunoblastic lymphoma, Stage III--IV or bulky Stage II disease, and an ECOG performance status of 0--1. CALGB 8852, a group-wide study, accrued 227 patients: 120 patients in the pilot study to determine the maximum tolerated dose (MTD) without G-CSF and 107 in the pilot study of dose-escalated CHOPE with G-CSF. CALGB 8854, a limited-institution, Phase I study, enrolled 38 patients and determined the MTD of CHOPE with G-CSF to be used in CALGB 8852. The MTD in both studies was defined as the dose at which 50% of patients had 1) Grade 4 neutropenia or thrombocytopenia lasting 7 days or more, or 2) Grade 3--4 hemorrhage or nonhematologic toxicity (excluding alopecia, nausea, and emesis), or 3) were prevented from receiving 100% of drug on Day 22. RESULTS: The MTD of CHOPE without G-CSF was cyclophosphamide 1000 mg/m(2) on Day 1 and etoposide 100 mg/m(2) on Days 1--3 with doxorubicin 50 mg/m(2) on Day 1, vincristine 1.4 mg/m(2) (maximum, 2 mg) on Day 1, and prednisone 100 mg on Days 1--5. With the addition of G-CSF at 200 microg/m(2) on Days 5--19, the MTD was cyclophosphamide 1500 mg/m(2) and etoposide 160 mg/m(2) on Days 1-3 with standard doses of doxorubicin, vincristine, and prednisone. Increasing the dose of G-CSF from 200 microg/m(2) to 400 microg/m(2) did not allow for further dose escalation. The primary toxicity in all cohorts was neutropenia. Four toxic deaths occurred on CALGB 8852. The 5-year failure free survival (FFS) and overall survival (OS) rates for eligible patients on CALGB 8852 were 31% (95% confidence interval [95%CI], 23--39) and 48% (95%CI, 40--57), respectively. The 5-year FFS and OS rates for eligible patients on CALGB 8854 were 34% (95%CI, 17--52) and 51% (95%CI, 33--70), respectively. CONCLUSIONS: Moderate dose escalation with G-CSF is feasible. However, response and survival rates of patients who receive dose-escalated CHOPE, even with the addition of G-CSF, appear similar to the rates reported with standard-dose CHOP.

Cyclophosphamide, doxorubicin, vincristine, prednisone, and etoposide (CHOPE) for advanced-stage Hodgkin's disease: CALGB 8856.

Successful treatment of advanced-stage Hodgkin's disease (HD) may critically depend on dose intensity. Because mechlorethamine, Oncovin, procarbazine, and prednisone (MOPP), and Adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) are not suitable for major dose escalation, we evaluated the activity and toxicity of combined cyclophosphamide, doxorubicin, vincristine, prednisone, and etoposide (CHOPE) in advanced HD, here used at conventional dose intensity, as a preparatory study prior to using this regimen at higher dose intensity. Ninety-two patients were treated with CHOPE (cyclophosphamide, 750 mg/m2, day 1; doxorubicin, 50 mg/m2, day 1; vincristine, 1.4 mg/m2, days 1 and 8; prednisone, 100 mg/day, days 1-5; and etoposide, 80 mg/m2, days 1, 2, and 3) every 21 days. All had advanced HD with no prior chemotherapy with 46% stage IV, 63% with B symptoms, and 57% with bulky disease (> 5 cm). Radiation and growth factor support were not permitted. Full-dose vincristine (not capped at maximum 2 mg/dose) was used in the first 33 patients. An initial cohort of 41 patients was treated with four cycles of CHOPE to evaluate safety and efficacy followed by four cycles of ABVD. A second cohort of 51 patients was treated with 6-8 cycles of CHOPE alone. Toxicity was generally acceptable and primarily hematologic, with neutrophils < 500 in 63% of cohort I and 90% of cohort II, and platelets < 25,000 in 7% of cohort I and 8% of cohort II. The long-term neurotoxicity of full-dose, high-intensity vincristine was acceptable and largely reversible. In cohort I, 92% of patients achieved a complete response (CR) or partial response (PR) with four cycles of CHOPE and 85% were in CR after four additional cycles of ABVD. In cohort II, 77% achieved a CR with 6-8 cycles of CHOPE alone. FFS was 76% in cohort I and 59% in cohort II, with a median follow-up of 8.2 and 5.7 years, respectively. CHOPE, at conventional dose intensity as used here, is an effective first-line regimen for the treatment of advanced-stage HD and may warrant evaluation using higher doses of cyclophosphamide and etoposide with granulocyte colony stimulating factor (G-CSF) support.

Persistent symptoms among survivors of Hodgkin's disease: an explanatory model based on classical conditioning.

Persistent symptoms of nausea, distress, and vomiting triggered by reminders of cancer treatment were examined among 273 Hodgkin's disease survivors, 1 to 20 years posttreatment. Prevalence rates were high for distress and nausea but low for vomiting. Retrospective report of anticipatory symptoms during treatment was the strongest predictor of persistent symptoms, suggesting that treatment-induced symptoms are less likely to persist if conditioning does not occur initially. Time since treatment was also a significant predictor, with patients more recently treated more likely to experience persistent symptoms. Thus, an explanatory model based on classical conditioning theory successfully predicted presence of persistent symptoms. Symptoms also were associated with ongoing psychological distress, suggesting that quality of life is diminished among survivors with persistent symptoms. Recommendations for prevention and treatment of symptoms are discussed.

High dose cyclophosphamide plus recombinant human granulocyte-colony stimulating factor (rhG-CSF) in the treatment of follicular, low grade non-Hodgkin's lymphoma: CALGB 9150.

The main objectives of this study were to determine the feasibility of administering high doses of cyclophosphamide plus recombinant human granulocyte-colony stimulating factor (rhG-CSF) every 14-21 days to patients with follicular small cleaved cell lymphoma. For each patient, the treatment was not considered feasible if fewer than four cycles of cyclophosphamide chemotherapy could be administered on schedule (i.e. at least every 29 days) or (1) hospitalization of the patient for longer than three days was necessary for neutropenic fever (38 degrees C) or bacteriologically documented infection in > 50% of the cycles, or (2) grade > or = 2 hemorrhage in association with thrombocytopenia of grade > or = 3 severity occurred in > 50% of the cycles or (3) non-hematologic toxicity (excluding nausea/vomiting and alopecia) of grade > or = 3 occurred in > 50% of cycles. The goal was to have a treatment program feasible in 75% or more of the treated patients. The secondary objectives were to determine the toxicities, the complete and partial response rates, and the time to treatment failure (TTF). The trial also attempted to assess the effectiveness of this treatment program in eradicating Bcl-2 rearrangements by PCR, and to assess complete remission duration in relationship to PCR results in patients who respond to this chemotherapy program. Patients were required to have histologically documented non-Hodgkin's lymphoma of the subtypes follicular, predominantly small cleaved cell (IWF-B) or follicular mixed, (IWF-C). Patients were required to have Stage IV disease including histologic evidence of bone marrow involvement. Measurable disease was required and patients were also required to have one of the following risk factors: > or = 2 extranodal sites, node or nodal group > or = 5 cm. Submission of fresh bone marrow for molecular genetic studies for the presence of Bcl-2-Ig fusion DNA was mandatory in previously untreated patients. Patients had to be between 18 and physiologic age 55 years (carefully selected patients over age 55 years were also eligible), expected survival > 2 years, performance status 0-1, and have adequate renal, hepatic and bone marrow function, and a cardiac ejection fraction > or = 50%. Cyclophosphamide 4.5 g/m2 i.v. was given with mesna every 14 days with rhG-CSF support. Twenty-nine patients were accrued to this trial. The median follow-up time is 5.0 years, with a range of 2.5-6.7 years. The overall response rate was 75% (9 CRs 37.5%, 9PRs 37.5%). The median duration of survival is 5.53 years. The 1-year estimated probability of freedom from treatment failure was 50% and of survival at 1 year was 92%. No strong association was observed between TTF and age, symptomatic stage, histology performance status, number of extranodal sites or baseline Bcl-2 status. At 3 years the survival of all patients was 78% and failure free survival was 17%. 15 (62%) of the 24 eligible previously untreated patients met the criteria for feasibility specified in the protocol. The 95% CI for the feasibility rate is (44 and 82%). Twenty-two of the 24 (92%) previously untreated patients had specimens submitted for testing for Bcl-2 rearrangements. Thirteen of the 22 (59%) were found to have rearrangements at baseline. Post-treatment specimens were submitted for seven of the 13 patients. Four of the seven converted to Bcl-2 negative following treatment. Eight of 13 Bcl-2 positive patients (62%) had a clinical response to treatment. The 95% exact binomial CI for the total response rate in this subgroup is (28 and 88%). This study demonstrates that repetitive doses of cyclophosphamide at 4.5 g/m2 every two weeks with rhG-CSF support can be administered to selected younger patients with advanced follicular lymphoma with morphologic involvement of the bone marrow with acceptable non-hematologic toxicity.

Phase II study of infusional chemotherapy with doxorubicin, vincristine and etoposide plus cyclophosphamide and prednisone (I-CHOPE) in resistant diffuse aggressive non-Hodgkin's lymphoma: CALGB 9255. Cancer and Leukemia Group B.

BACKGROUND: Patients with resistant diffuse aggressive non-Hodgkin's lymphoma (DA-NHL) have a poor prognosis. Studies have suggested infusional therapy may be beneficial. PATIENTS AND METHODS: This trial used an infusional regimen called I-CHOPE in resistant patients who had previously received only bolus CHOPE or CHOP regimen. Resistance was defined as: a) primary refractory disease, b) progression on therapy, c) partial response, d) complete remission lasting less than one year. Eligibility criteria included a diagnosis of DA-NHL (IWF E-H), no prior irradiation and adequate organ function. RESULTS: Thirty-seven patients were entered and twenty-nine were eligible. Reasons for ineligibility were incorrect histology (5) and other (3). The median age was 57 years (range 29-81) with 21 males. The performance status scores were: 0 (12 patients); 1 (9 patients); 2 (8 patients). Prior therapy consisted of standard CHOP (26 patients), bolus CHOPE (2 patients), high dose CHOP (1 patient). Therapy consisted of a 120 hour continuous intravenous infusion of doxorubicin 10 mg/m2/day, vincristine 0.28 mg/m2/day (maximum 0.4 mg/day), and etoposide 48 mg/m2/day. Cyclophosphamide 750 mg/m2 was given as an i.v. bolus day 6 and prednisone was given at 100 mg/day p.o. on days 1-5. G-CSF was allowed for myelosuppression. The overall response rate was 48% (CR 17%; PR 31%). Freedom from progression was 24% at six months and 8% at one year. Survival was 69% at six months and 40% at one year. In an exploratory analysis a prior CR or PR predicted response to I-CHOPE. Twelve of sixteen patients who had a CR/PR on previous therapy responded while two of thirteen who had no prior response, responded to I-CHOPE (P = 0.003). The toxicity was tolerable with grade 3-4 hematologic toxicity being leucopenia 94% and thrombocytopenia 41%. The grade 3-4 non-hematologic toxicities were infection in 28%, phlebitis in 11%, and stomatitis in 15%. CONCLUSIONS: I-CHOPE can induce responses in this group of patients with a poor prognosis, but most were seen in those who had previously had a response to bolus chemotherapy.

Response criteria for NHL: importance of 'normal' lymph node size and correlations with response rates.

BACKGROUND: Oncologic literature cites many different definitions of critical response measurements. PATIENTS AND METHODS: Response criteria (RC) for non-Hodgkin's lymphoma (NHL) were developed by lymphoma experts, endorsed by international lymphoma clinicians, and applied to a 166-patient rituximab (Rituxan, MabThera) trial by a third-party, blinded panel of NHL experts (LEXCOR). Retrospectively, we analyzed this data using variations of the original RC and comparing with recently published RC. RESULTS: The definition of a 'normal' lymph node affected the complete response (CR) rate (< or = 1.0 x 1.0 cm, 6%; < or = 1.5 x 1.5 cm, 18%; < or = 2.0 x 2.0 cm, 28%); overall response rate (ORR) was not affected. CR rates increased progressively without > or = 28 days response confirmation: 12% vs. 6% (< or = 1.0 x 1.0 cm), 26% vs. 18% (< or = 1.5 x 1.5 cm), and 36% vs. 28% (< or = 2.0 x 2.0 cm). CR rate and duration of response (DR) were unaffected when only the six largest, rather than all lesions, were measured. When the new RC were applied, CR rate (32%) was higher and DR (13.9 months) and time to progression (15.6 months) were shorter in complete responders. CONCLUSIONS: Standard RC must be consistently and rigorously applied for accurate comparisons between studies.

The effects of an educational intervention on calcium intake and bone mineral content in young women with low calcium intake.

PURPOSE: This study evaluated whether a combined behavioral and dietary intervention would affect young women's calcium intake and bone mineral content (BMC). DESIGN: The design was a two by three mixed design with one between-subjects factor (treatment vs. control) and one within-subjects factor (time--baseline, 3-month, and 6-month). SETTING: The study was conducted in a university setting in Memphis, Tennessee. PARTICIPANTS: A total of 80 premenopausal women (ages 18 to 30) with low baseline calcium intake (< 700 mg/d) were included in the analyses. There were 40 women in the treatment group and 40 women in the control group. MEASURES: Hertzler and Frary's rapid assessment questionnaire was employed to evaluate calcium intake, and dual-energy x-ray absorptiometry (DEXA) was employed to assess BMC. RESULTS: Repeated measures analysis of variance (RM ANOVA) was employed to analyze results. Results indicated that women in the treatment group made greater increases in total calcium intake and supplemental calcium than women in the control group and that all women made significant increases in dietary calcium intake. Additionally, analyses of BMC revealed that women in the treatment group did not experience significant changes in total BMC, and women in the control group experienced significant losses in total BMC. CONCLUSIONS: In the current study, women were losing BMC, and the women who made the largest increases in calcium intake were able to retard this bone loss. There is increasing evidence that dietary calcium intake in young people is extremely low, and the results of the current study highlight the need for much more intensive evaluations investigating the factors that are positively associated with premenopausal bone mineral change.

Current treatment of follicular low-grade lymphomas.

The follicular lymphomas are the most common subtype of indolent non-Hodgkin's lymphoma in adults, with approximately 20,000 new cases annually in the United States, most of which are disseminated at diagnosis. Despite far-advanced stage, frequently including the bone marrow, median life expectancy is relatively long compared with other common subtypes of lymphoma, falling within the range of 7 to 10 years. Follicular low-grade lymphomas respond very well to most therapeutic interventions. Overall response rates are generally above 90%, but complete response rates are quite variable, often reflecting the duration rather than the intensity of treatment. Unfortunately, the clinical course is usually characterized by multiple remissions and relapses, even after complete remissions. Regardless of the initial treatment chosen, most patients eventually die of the lymphoma. Multiple attempts have been made over the past two decades to improve the survival for patients with follicular lymphomas, and a large number of phase III trials have been reported. These have included a variety of different therapeutic interventions, such as combination chemotherapy, recombinant interferons, new cytotoxic drugs, and immunologic agents. Although some results suggest differential benefits in selected groups of patients, most studies have not demonstrated that the use of a particular therapy convincingly prolongs survival.

Sequential chemotherapy (etoposide, vinblastine, and doxorubicin) and subtotal lymph node radiation for patients with localized Hodgkin disease and unfavorable prognostic features: A phase II Cancer and Leukemia Group B Study (9051).

BACKGROUND: The aim of this study was to evaluate a regimen of sequential chemotherapy and radiotherapy for patients with Hodgkin disease. METHODS: The Cancer and Leukemia Group B conducted a Phase II study of three cycles of etoposide, vinblastine, and doxorubicin (EVA) chemotherapy followed by subtotal lymph node radiation for patients with localized Hodgkin disease and unfavorable prognostic features. Fifty-nine patients were enrolled in the study. Fifty-three patients met all study eligibility criteria; 48 of them (91%) had mediastinal disease and 29 (55%) had bulky mediastinal disease. RESULTS: A complete response (CR) occurred in 35 of the patients (66%). Of all patients who had CR, 26% had the CR after the chemotherapy and before the radiation, and 74% after the chemotherapy and radiation. Twenty percent of the patients who had CR experienced disease progression; in these patients, the progression was outside the radiotherapy field in the lung and involved widespread disease. CONCLUSIONS: EVA offers a nonbleomycin-containing alternative for patients in whom preexisting pulmonary disease may be exacerbated by bleomycin and radiation therapy. EVA, as given in this study (in three cycles), was insufficient chemotherapy for patients who had disease in areas outside the radiation fields (occult disease).

High-dose therapy and transplantation in non-Hodgkin's lymphoma.

High-dose therapy and transplantation have been explored as a therapeutic option for patients with non-Hodgkin's lymphomas (NHLs) for the past two decades, in an effort to improve the long-term outcome of this spectrum of disorders. Although a plethora of pilot and phase II studies in the various subtypes of NHL have been reported, there is a problematic lack of randomized phase III trials that would aid in answering important questions regarding the role of transplantation in these disease processes. The results of transplantation trials for these patients are also confounded by the relatively short follow-up intervals in low-grade NHL and small patient numbers in studies of transplantation for less common NHL subtypes, such as lymphoblastic, Burkitt's, and mantle cell lymphomas. The emerging late toxicities of transplantation are of increasing concern and underscore the need for more studies that address questions of relative therapeutic benefits. Fortunately, the limitations of these existing studies are recognized, and new transplantation trials presently underway or in development are beginning to address these concerns. As clinical transplantation moves into a more mature phase, these phase III studies should provide more definitive answers as to the specific role of transplantation in specific subtypes of NHL.

Comparison of psychosocial adaptation of advanced stage Hodgkin's disease and acute leukemia survivors. Cancer and Leukemia Group B.

BACKGROUND: The purpose of this study was to compare the long-term psychosocial adaptation of Hodgkin's disease and adult acute leukemia survivors. PATIENTS AND METHODS: Two hundred seventy-three Hodgkin's disease (HD) and 206 adult acute leukemia (AL) survivors were interviewed by telephone concerning their psychosocial adjustment and problems they attributed to having been treated for cancer, using identical research procedures and a common set of instruments. The following measures were used: Psychosocial Adjustment to Illness Scale (PAIS); Brief Symptom Inventory (BSI); current Conditioned Nausea and Vomiting triggered by treatment-related stimuli (CNVI); Indices of Employment, Insurance and Sexual Problems Attributed to Cancer; Negative Socioeconomic Impact of Cancer Index (NSI). All participants had been treated on one of nine Hodgkin's disease or 13 acute leukemia Cancer and Leukemia Group B (CALGB) clinical trials from 1966-1988, and had been off treatment for one year or more (mean years: HD = 5.9; AL = 5.6). RESULTS: HD survivors' risk of having a high distress score on the BSI was almost twice that found for AL survivors (odds ratio = 1.90), with 21% of HD vs. 14% of AL survivors (P < 0.05) having scores that were 1.5 standard deviations above the norm, suggestive of a possible psychiatric disorder. HD survivors reported greater fatigue (POMS Fatigue, P = 0.01; Vigor Subscales, P = 0.001), greater conditioned nausea (CNVI, P < 0.05), greater impact of cancer on their family life (PAIS Domestic Environment, P = 0.004) and poorer sexual functioning (PAIS Sexual Relationships, P = 0.0001), than AL survivors. CONCLUSIONS: Treatment-related issues may have placed HD survivors at a greater risk for problems in long-term adaptation than AL survivors.

MOPP/ABV hybrid chemotherapy for advanced Hodgkin's disease significantly improves failure-free and overall survival: the 8-year results of the intergroup trial.

PURPOSE: To compare the efficacy of sequential mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) followed by doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) versus the MOPP/ABV hybrid regimen in advanced-stage Hodgkin's disease. PATIENTS AND METHODS: A total of 737 patients with previously untreated stages III2A, IIIB, IVA, or IVB Hodgkin's disease and patients in first relapse after radiotherapy were prospectively randomized to sequential MOPP-ABV or MOPP/ABV hybrid. Of 691 eligible patients, 344 received the sequential regimen and 347 received the hybrid. RESULTS: The overall response rate was 95%, with complete responses (CRs) in 79%: 83% on the MOPP/ABV hybrid and 75% on the sequential MOPP-ABVD arm (P = .02). With a median follow-up time of 7.3 years, the 8-year failure-free survival (FFS) rates were 64% for MOPP/ABV hybrid and 54% far sequential MOPP-ABVD (P = .01; 0.69 relative risk of failure, comparing MOPP/ABV hybrid v MOPP-ABVD). The 8-year overall survival rate was significantly better for the MOPP/ABV hybrid (79%) as compared with sequential MOPP-ABVD (71%) (P = .02; relative risk, 0.65). MOPP/ABV hybrid had significantly more life-threatening or fatal neutropenia and pulmonary toxicity than the sequential MOPP-ABVD arm, which was associated with significantly greater thrombocytopenia. Nine cases of acute myelogenous leukemia or myelodysplasia were reported on the sequential regimen as compared with only one on the hybrid (P = .01). CONCLUSION: MOPP/ABV hybrid chemotherapy was significantly more effective than sequential MOPP-ABVD. FFS and overall survival were significantly improved on the hybrid arm, which was also associated with a lower incidence of acute leukemia or myelodysplasia.

Delphi-panel analysis of appropriateness of high-dose chemotherapy and blood cell or bone marrow autotransplants in diffuse large-cell lymphoma.

Although high-dose chemotherapy and a blood cell or bone marrow autotransplant are commonly used to treat people with diffuse large-cell lymphoma, there is controversy whether this is better than conventional-dose chemotherapy. Subject-selection and time-to-treatment biases preclude comparison of data from uncontrolled trials and there are few date from randomized trials. We used a Delphi-panel group judgment process to determine appropriateness of high-dose chemotherapy and a blood cell or bone marrow transplant. Results were compared to those of randomized trials. Nine lymphoma experts from diverse geographic sites and practice settings were panelists. Boolean MEDLINE searches of lymphoma and chemotherapy and an autotransplant formed the dataset. Panelists were asked to rate appropriateness of high-dose chemotherapy and an autotransplant compared to conventional-dose chemotherapy. Clinical variables were permuted to define 80 clinical settings rated by the panelists on a 9-point ordinal scale. Results were used to determine an appropriateness index reflecting the mean and distribution of ratings. The relationship of appropriateness indices to permuted clinical variables was considered by analysis of variance and recursive partitioning. In people with initial diffuse large-cell lymphoma, autotransplants were never rated appropriate. They were rated uncertain in all settings except in people never receiving chemotherapy and in those with a complete response to chemotherapy and an international prognostic index < 3, where they were rated inappropriate. In people with recurrent lymphoma, autotransplants were rated appropriate in those with a complete or partial response to chemotherapy, uncertain in those with a less than partial response and in those not receiving re-induction chemotherapy and inappropriate in people with CNS lymphoma. These conclusions agree with results of randomized trials.
