Abstract
PURPOSE To evaluate mediators of resumption of menses (ROM) in adolescents with anorexia nervosa (AN). METHODS Anthropometrics, body composition by dual-energy X-ray absorptiometry, hormonal studies, and responses to mental health screens were obtained at 6-month intervals for 18 months in 37 adolescents with AN randomized to the placebo arm of a double-blind treatment trial. Outcomes were compared between subjects with menstrual recovery and those without. RESULTS Twenty-four subjects (65%) had ROM. Higher percentage body fat was associated with ROM (odds ratio, 1.19; 95% confidence interval, 1.06, 1.33; p < .01), as was body mass index and percent median body weight. Estradiol ≥30 ng/mL alone did not predict menses (p = .08) but was associated with ROM when coupled with percent mean body weight (odds ratio, 2.49; 95% confidence interval, 1.09, 5.65; p = .03). Changes in leptin, cortisol, and mental health were not associated with return of menses. CONCLUSIONS Percentage body fat may be an additional, useful clinical assessment to follow in caring for adolescents with AN.

Abstract
Young children are disproportionately exposed to interpersonal trauma (maltreatment, witnessing intimate partner violence [IPV]) and appear particularly susceptible to negative sequelae. Little is known about the factors influencing vulnerability to traumatic stress responses and other negative outcomes in early life. This study examined associations among interpersonal trauma exposure, sociodemographic risk, developmental competence, and posttraumatic stress disorder (PTSD) symptoms in 200 children assessed from birth to first grade via standardized observations, record reviews, and maternal and teacher interviews. More severe PTSD symptoms were predicted by greater trauma exposure (r = .43), greater sociodemographic risk (r = .22), and lower developmental competence (rs=−.31 and −.54 for preschool and school-age developmental competence, respectively). Developmental competence partially mediated the association between trauma exposure and symptoms. Trauma exposure fully mediated the association between sociodemographic risk and symptoms. Neither sociodemographic risk nor developmental competence moderated trauma exposure effects on symptoms. The findings suggest that (a)exposure to maltreatment and IPV has additive effects on posttraumatic stress risk in early life, (b) associations between sociodemographic adversity and poor mental health may be attributable to increased trauma exposure in disadvantaged populations, and (c) early exposures have a negative cascade effect on developmental competence and mental health.

Abstract
BACKGROUND Peanut allergy is a major public health problem that affects 1% of the population and has no effective therapy. OBJECTIVE To examine the safety and efficacy of oral desensitization in peanut-allergic children in combination with a brief course of anti-IgE mAb (omalizumab [Xolair]). METHODS We performed oral peanut desensitization in peanut-allergic children at high risk for developing significant peanut-induced allergic reactions. Omalizumab was administered before and during oral peanut desensitization. RESULTS We enrolled 13 children (median age, 10 years), with a median peanut-specific IgE level of 229 kU(A)/L and a median total serum IgE level of 621 kU/L, who failed an initial double-blind placebo-controlled food challenge at peanut flour doses of 100 mg or less. After pretreatment with omalizumab, all 13 subjects tolerated the initial 11 desensitization doses given on the first day, including the maximum dose of 500 mg peanut flour (cumulative dose, 992 mg, equivalent to >2 peanuts), requiring minimal or no rescue therapy. Twelve subjects then reached the maximum maintenance dose of 4000 mg peanut flour per day in a median time of 8 weeks, at which point omalizumab was discontinued. All 12 subjects continued on 4000 mg peanut flour per day and subsequently tolerated a challenge with 8000 mg peanut flour (equivalent to about 20 peanuts), or 160 to 400 times the dose tolerated before desensitization. During the study, 6 of the 13 subjects experienced mild or no allergic reactions, 5 subjects had grade 2 reactions, and 2 subjects had grade 3 reactions, all of which responded rapidly to treatment. CONCLUSIONS Among children with high-risk peanut allergy, treatment with omalizumab may facilitate rapid oral desensitization and qualitatively improve the desensitization process.

Abstract
PURPOSE To investigate the associations between momentary social context and glucose monitoring adherence in adolescents with type 1diabetes (T1D). METHODS For 14 days, patients (14-18 years old, T1D duration >1 year) of a pediatric diabetes clinic carried handheld computers that prompted them to report their location, companionship, and attitudes toward companions at the times they usually checked their glucose, and again 30 minutes later to report whether they checked their glucose and, if not, why. Associations between social context factors and checking glucose (adherence) were analyzed using logistic generalized estimating equations and adjusted for age, sex, duration of T1D, and pump use. RESULTS Thirty-six participants (mean age 16.6 ± 1.5 years, mean duration of T1D 8.7 ± 4.4 years) completed 971 context and 1,210 adherence reports, resulting in 805 paired reports. Median signal response rate was 63%. The odds of checking glucose was higher when participants expressed very strong desire to blend in (adjusted odds ratio [AOR] = 2.30, 95% confidence interval 1.07-4.94, p = .03). Strong desire to impress others was associated with decreased likelihood of checking glucose (AOR = .52, 95% confidence interval .28-.97, p = .04.) Location, solitude, type of companion, and attitudes toward companions were not significantly associated with checking glucose. CONCLUSIONS Desire to blend in may support glucose monitoring adherence and desire to impress others may impede this behavior in adolescents with T1D. Other dimensions of social context were not linked to checking glucose in this study.

Abstract
BACKGROUND Dietary and physical activity (PA) behaviors can predict disordered weight control behaviors (DWCB) among youth. This study examines dietary and PA correlates of DWCB and differences by race/ethnicity and weight status in a diverse sample of youth. METHODS Self-reported data on dietary weight management behaviors, strengthening/toning exercises, moderate-to-vigorous physical activity, and DWCB (vomiting, taking laxatives, and/or taking diet pills without a prescription) were obtained from 15,260 sixth to eighth graders in 47 middle schools participating in the Massachusetts Healthy Choices Study at baseline (2005). Generalized estimating equations were used to estimate odds of DWCB associated with dietary and PA behaviors and to examine for differences by race/ethnicity and weight status, adjusting for covariates and clustering of individuals within schools. RESULTS Disordered weight control behaviors were reported by 3.6% of girls and 3.1% of boys. Youth who engaged in strengthening/toning exercises 7 days per week versus 0-3 days per week had increased odds of DWCB (girls odds ratio [OR] = 1.9; 95% confidence interval [CI] = 1.3 - 3.0; boys OR = 1.5; 95% CI = 1.0 - 2.2). Dietary weight management behaviors were associated with increased odds of DWCB (girls OR = 1.2; 95% CI = 1.1 - 1.3; boys OR = 1.3; 95% CI = 1.2 - 1.4) for each additional behavior. These associations did not differ by race/ethnicity or weight status. CONCLUSIONS Persons promoting healthy dietary and PA behaviors among youth should consider the co-occurrence of strengthening/toning and dietary weight management behaviors with DWCB and the consistency in these associations across racial/ethnic and weight status groups.

Abstract
BACKGROUND The purpose of the present study was to determine if the duration of symptoms affects outcomes following the treatment of intervertebral lumbar disc herniation. METHODS An as-treated analysis was performed on patients enrolled in the Spine Patient Outcomes Research Trial (SPORT) for the treatment of intervertebral lumbar disc herniation. Randomized and observational cohorts were combined. A comparison was made between patients who had had symptoms for six months or less (n = 927) and those who had had symptoms for more than six months (n = 265). Primary and secondary outcomes were measured at baseline and at regular follow-up intervals up to four years. The treatment effect for each outcome measure was determined at each follow-up period for the duration of symptoms for both groups. RESULTS At all follow-up intervals, the primary outcome measures were significantly worse in patients who had had symptoms for more than six months prior to treatment, regardless of whether the treatment was operative or nonoperative. When the values at the time of the four-year follow-up were compared with the baseline values, patients in the operative treatment group who had had symptoms for six months or less had a greater increase in the bodily pain domain of the Short Form-36 (SF-36) (mean change, 48.3 compared with 41.9; p < 0.001), a greater increase in the physical function domain of the SF-36 (mean change, 47.7 compared with 41.2; p < 0.001), and a greater decrease in the Oswestry Disability Index score (mean change, -41.1 compared with -34.6; p < 0.001) as compared with those who had had symptoms for more than six months (with higher scores indicating less severe symptoms on the SF-36 and indicating more severe symptoms on the Oswestry Disability Index). When the values at the time of the four-year follow-up were compared with the baseline values, patients in the nonoperative treatment group who had had symptoms for six months or less had a greater increase in the bodily pain domain of the SF-36 (mean change, 31.8 compared with 21.4; p < 0.001), a greater increase in the physical function domain of the SF-36 (mean change, 29.5 compared with 22.6; p = 0.015), and a greater decrease in the Oswestry Disability Index score (mean change, -24.9 compared with -18.5; p = 0.006) as compared with those who had had symptoms for more than six months. Differences in treatment effect between the two groups related to the duration of symptoms were not significant. CONCLUSIONS Increased symptom duration due to lumbar disc herniation is related to worse outcomes following both operative and nonoperative treatment. The relative increased benefit of surgery compared with nonoperative treatment was not dependent on the duration of the symptoms.

Abstract
The current study examined associations between maternal posttraumatic stress disorder (PTSD) symptoms and infant emotional reactivity and emotion regulation during the first year of life in a primarily low-income, urban, ethnic/racial minority sample of 52 mother-infant dyads. Mothers completed questionnaires assessing their own trauma exposure history and current PTSD and depressive symptoms and their infants' temperament when the infants were 6 months old. Dyads participated in the repeated Still-Face Paradigm (SFP-R) when the infants were 6 months old, and infant affective states were coded for each SFP-R episode. Mothers completed questionnaires assessing infant trauma exposure history and infant current emotional and behavioral symptoms when the infants were 13 months old. Maternal PTSD symptoms predicted infants' emotion regulation at 6 months as assessed by (a) infant ability to recover from distress during the SFP-R and (b) maternal report of infant rate of recovery from distress/arousal in daily life. Maternal PTSD symptoms also predicted maternal report of infant externalizing, internalizing, and dysregulation symptoms at 13 months. Maternal PTSD was not associated with measures of infant emotional reactivity. Neither maternal depressive symptoms nor infant direct exposure to trauma accounted for the associations between maternal PTSD symptoms and infant outcomes. These findings suggest that maternal PTSD is associated with offspring emotion regulation difficulties as early as infancy. Such difficulties may contribute to increased risk of mental health problems among children of mothers with PTSD.

Abstract
STUDY DESIGN As-treated analysis of the Spine Patient Outcomes Research Trial. OBJECTIVE To compare baseline characteristics and surgical and nonoperative outcomes in degenerative spondylolisthesis (DS) and spinal stenosis (SpS) patients stratified by predominant pain location (i.e., leg vs. back). SUMMARY OF BACKGROUND DATA Evidence suggests that DS and SpS patients with predominant leg pain may have better surgical outcomes than patients with predominant low back pain (LBP). METHODS The DS cohort included 591 patients (62% underwent surgery), and the SpS cohort included 615 patients (62% underwent surgery). Patients were classified as leg pain predominant, LBP predominant, or having equal pain according to baseline pain scores. Baseline characteristics were compared between the 3 predominant pain location groups within each diagnostic category, and changes in surgical and nonoperative outcome scores were compared for 2 years. Longitudinal regression models including baseline covariates were used to control for confounders. RESULTS Among DS patients at baseline, 34% had predominant leg pain, 26% had predominant LBP, and 40% had equal pain. Similarly, 32% of SpS patients had predominant leg pain, 26% had predominant LBP, and 42% had equal pain. DS and SpS patients with predominant leg pain had baseline scores indicative of less severe symptoms. Leg pain predominant DS and SpS patients treated surgically improved significantly more than LBP predominant patients on all primary outcome measures at 1 and 2 years. Surgical outcomes for the equal pain groups were intermediate to those of the predominant leg pain and LBP groups. The differences in nonoperative outcomes were less consistent. Conclusion. Predominant leg pain patients improved significantly more with surgery than predominant LBP patients. However, predominant LBP patients still improved significantly more with surgery than with nonoperative treatment.

Abstract
PURPOSE To characterize the inter- and intraobserver variability of qualitative, non-disk contour degenerative findings of the lumbar spine at magnetic resonance (MR) imaging. MATERIALS AND METHODS The case accrual method used to perform this institutional review board-approved, HIPAA-compliant retrospective study was the random selection of 111 interpretable MR examination cases of subjects from the Spine Patient Outcomes Research Trial. The subjects were aged 18-87 years (mean, 53 years +/- 16 [standard deviation]). Four independent readers rated the cases according to defined criteria. A subsample of 40 MR examination cases was selected for reevaluation at least 1 month later. The following findings were assessed: spondylolisthesis, disk degeneration, marrow endplate abnormality (Modic changes), posterior anular hyperintense zone (HIZ), and facet arthropathy. Inter- and intraobserver agreement in rating the data was summarized by using weighted kappa statistics. RESULTS Interobserver agreement was good (kappa = 0.66) in rating disk degeneration and moderate in rating spondylolisthesis (kappa = 0.55), Modic changes (kappa = 0.59), facet arthropathy (kappa = 0.54), and posterior HIZ (kappa = 0.44). Interobserver agreement in rating the extent of Modic changes was moderate: kappa Values were 0.43 for determining superior anteroposterior extent, 0.47 for determining superior craniocaudal extent, 0.57 for determining inferior anteroposterior extent, and 0.48 for determining inferior craniocaudal extent. Intraobserver agreement was good in rating spondylolisthesis (kappa = 0.66), disk degeneration (kappa = 0.74), Modic changes (kappa = 0.64), facet arthropathy (kappa = 0.69), and posterior HIZ (kappa = 0.67). Intraobserver agreement in rating the extent of Modic changes was moderate, with kappa values of 0.54 for superior anteroposterior, 0.60 for inferior anteroposterior, 0.50 for superior craniocaudal, and 0.60 for inferior craniocaudal extent determinations. CONCLUSION The interpretation of general lumbar spine MR characteristics has sufficient reliability to warrant the further evaluation of these features as potential prognostic indicators.

Abstract
PURPOSE Limited previous data suggest that heterogeneity exists in the treatment approaches for women with ductal carcinoma in situ (DCIS). We sought in a longitudinal cohort study of women with DCIS to assess the attitudes and management approaches toward DCIS among physicians who provide care to women. MATERIALS AND METHODS Eligible physicians were invited to participate in a 1-time mailed survey. A financial incentive and reminders were used to enhance the response rate. Physician perception of risks associated with DCIS for patients and management approaches were evaluated. RESULTS Two hundred and eight physicians were identified, and 151 (73%) completed the survey. Respondents had a median age of 49 years (range, 32-75 years), and most were surgeons or medical oncologists (66%). Eighty-eight percent reported seeing an average of >or= 1 new patient with DCIS per month. In a multivariable model, physicians who cared for proportionately fewer patients with breast cancer were more likely to view DCIS as a riskier disease to a patient's overall health compared with physicians who cared for more women with breast cancer (odds ratio, 2.2; 95% CI, 1.1-4.6; P = .036). Physicians exhibited differences in management approaches when considering theoretical patients with DCIS and did not use consistent terms when speaking with patients with DCIS. CONCLUSION Substantial variation exists among physicians regarding perceptions and management approaches for women with DCIS. In some settings, risks of physician-recommended therapy might outweigh benefits. Further evaluation of the effects of physician management approaches and attitudes about DCIS on patient outcomes is warranted.

Abstract
BACKGROUND Surgery for spinal stenosis is widely performed, but its effectiveness as compared with nonsurgical treatment has not been shown in controlled trials. METHODS Surgical candidates with a history of at least 12 weeks of symptoms and spinal stenosis without spondylolisthesis (as confirmed on imaging) were enrolled in either a randomized cohort or an observational cohort at 13 U.S. spine clinics. Treatment was decompressive surgery or usual nonsurgical care. The primary outcomes were measures of bodily pain and physical function on the Medical Outcomes Study 36-item Short-Form General Health Survey (SF-36) and the modified Oswestry Disability Index at 6 weeks, 3 months, 6 months, and 1 and 2 years. RESULTS A total of 289 patients were enrolled in the randomized cohort, and 365 patients were enrolled in the observational cohort. At 2 years, 67% of patients who were randomly assigned to surgery had undergone surgery, whereas 43% of those who were randomly assigned to receive nonsurgical care had also undergone surgery. Despite the high level of nonadherence, the intention-to-treat analysis of the randomized cohort showed a significant treatment effect favoring surgery on the SF-36 scale for bodily pain, with a mean difference in change from baseline of 7.8 (95% confidence interval, 1.5 to 14.1); however, there was no significant difference in scores on physical function or on the Oswestry Disability Index. The as-treated analysis, which combined both cohorts and was adjusted for potential confounders, showed a significant advantage for surgery by 3 months for all primary outcomes; these changes remained significant at 2 years. CONCLUSIONS In the combined as-treated analysis, patients who underwent surgery showed significantly more improvement in all primary outcomes than did patients who were treated nonsurgically.

Abstract
BACKGROUND Since 1992, pharmaceutical industry support has surpassed National Institutes of Health funding for clinical research in the United States. In this study, the authors sought to evaluate the impact of this shift in funding from public to private sponsors on the nature of published breast cancer clinical research. METHODS All published breast cancer clinical trials from 2003, 1998, and 1993 were reviewed from 10 select English-language medical journals to evaluate pharmaceutical involvement over time and the association between sponsorship, trial design, and results. Clinical studies that reported disease-specific outcomes from medical therapy for breast cancer were eligible for analysis. Pharmaceutical involvement was defined as reported pharmaceutical industry funding, provision of drug, and/or authorship for each publication. RESULTS In total, 140 eligible studies were identified, including 45 studies that were published in 1993, 39 studies that were published in 1998, and 56 studies that were published in 2003. Among those, 67 publications (48%) reported pharmaceutical industry involvement, 36 publications (26%) had at least >/=1 pharmaceutical industry author, And 100 publications (71%) were considered positive. Pharmaceutical involvement was identified in 44% of the studies published in 1993, in 38% of the studies published in 1998, and in 58% of the studies published in 2003. Pharmaceutical authorship was reported in 22% of the 1993 studies, in 21% of the 1998 studies, and in 34% of the 2003 studies. For studies that were published in 2003, those that reported pharmaceutical involvement were more likely to be positive (84% vs 54%; P = .02; Fisher exact test), to be single-arm studies (66% vs 33%; P = .03), and to evaluate metastatic disease (72% vs 46%; P = .06). CONCLUSIONS Pharmaceutical involvement in published clinical breast cancer research may affect study design, focus, and results. Further research is warranted, including analysis of unpublished studies, to evaluate the impact of increasing pharmaceutical industry involvement on clinical research.

Abstract
Chromosomal hyperdiploidy is the defining genetic signature in 40-50% of myeloma (MM) patients. We characterize hyperdiploid-MM (H-MM) in terms of its clinical and prognostic features in a cohort of 220 H-MM patients entered into clinical trials. Hyperdiploid-myeloma is associated with male sex, kappa immunoglobulin subtype, symptomatic bone disease and better survival compared to nonhyperdiploid-MM (median overall survival 48 vs 35 months, log-rank P = 0.023), despite similar response to treatment. Among 108 H-MM cases with FISH studies for common genetic abnormalities, survival is negatively affected by the existence of immunoglobulin heavy chain (IgH) translocations, especially those involving unknown partners, while the presence of chromosome 13 deletion by FISH did not significantly affect survival (median overall survival 50 vs 47 months, log-rank P = 0.47). Hyperdiploid-myeloma is therefore a unique genetic subtype of MM associated with improved outcome with distinct clinical features. The existence of IgH translocations but not chromosome 13 deletion by FISH negatively impacts survival and may allow further risk stratification of this population of MM patients.

Abstract
This multicenter, open-label, randomized phase 2 study evaluated 2 dose regimens of lenalidomide for relapsed, refractory myeloma. Seventy patients were randomized to receive either 30 mg once-daily or 15 mg twice-daily oral lenalidomide for 21 days of every 28-day cycle. Patients with progressive or stable disease after 2 cycles received dexamethasone. Analysis of the first 70 patients showed increased grade 3/4 myelo-suppression in patients receiving 15 mg twice daily (41% versus 13%, P = .03). An additional 32 patients received 30 mg once daily. Responses were evaluated according to European Group for Blood and Marrow Transplantation (EBMT) criteria. Overall response rate (complete, partial, or minor) to lenalidomide alone was 25% (24% for once-daily and 29% for twice-daily lenalidomide). Median overall survival in 30-mg once-daily and twice-daily groups was 28 and 27 months, respectively. Median progression-free survival was 7.7 months on once-daily versus 3.9 months on twice-daily lenalidomide (P = .2). Dexamethasone was added in 68 patients and 29% responded. Time to first occurrence of clinically significant grade 3/4 myelosuppression was shorter in the twice-daily group (1.8 vs 5.5 months, P = .05). Significant peripheral neuropathy and deep vein thrombosis each occurred in only 3%. Lenalidomide is active and well tolerated in relapsed, refractory myeloma, with the 30-mg once-daily regimen providing the basis for future studies as monotherapy and with dexamethasone.

Abstract
The biological and clinical implications of p16 gene methylation in multiple myeloma (MM) are still unclear despite previous studies. In this comprehensive study, using methylation-specific PCR (MS-PCR), we show that p16 methylation is relatively common and occurs in monoclonal gammopathy of undetermined significance (MGUS; n=17), smoldering multiple myeloma (SMM; n=40), and MM (n=522) at a prevalence of 24%, 28%, and 34%, respectively. However, p16 methylation does not appear to affect gene expression level. In a large cohort of patients with long-term follow-up information (n=439), there was no difference in overall survival between patients with or without p16 methylation. We also found no association between p16 methylation and the main cytogenetic categories, although it was more common among patients with 17p13.1 deletions (p53 locus), a genetic progression event in MM. In addition, p16 methylation has no apparent effect on the cycle because there was also no difference in the plasma cell labeling index (a direct measurement of proliferation) between patients with and without p16 methylation. Our results question a major role for p16 methylation in the oncogenesis of the PC neoplasm, and we now believe p16 methylation may be a marker for overall epigenetic changes associated with disease progression, with no obvious direct biological or clinical consequences.

Abstract
17516 Background: The p53 tumor suppressor is commonly inactivated by mutations. Even in tumors without mutations, there are defects in the response to p53 activation. In MM, the prognostic significance of p53 mutation is unknown, while there has been no systematic study of p53 function. We seek to address these issues in this study. Methods: p53 mutation was studied by conformation sensitive gel electrophoresis with primers encompassing exons 1 to 10 followed by sequencing of DNA fragments with altered electrophoretic pattern in newly diagnosed MM patients entered into ECOG E9486 trial where patients were randomized to receive variations of melphalan-based conventional chemotherapy (VBMCP). Fisher’s exact tests were used to compare variables between patients. Kaplan-Meier survival curves were compared using the log-rank test. To investigate p53 function, we analyzed the expression of p53, and 3 of its transcriptional targets, APAF1, p21 and MDM2, in a separate cohort of 15 normal plasma cells (PC), 14 MGUS, 13 smoldering myeloma (SMM) and 101 MM (73 new and 28 relapsed) from the Mayo Clinic who had gene expression profiling performed on the Affymetrix U133A chip (Santa Clara, Ca). Results: Two hundred and sixty-eight patients had enough materials for study and were included in the analysis. The prevalence of p53 mutation was 3% (n = 9). Five of the 9 patients (56%, p = 0.001) with mutations also had p53 deletion (studied by fluorescent in-situ hybridization) resulting in bi-allelic loss of p53. Soft tissue plasmacytomas (37% v 7%, p = 0.018), and among the common translocations, t(4;14) and t(14;16) (50% v 18%) were more common in patients with p53 mutations. Despite similar response to treatment, those with p53 mutation had very short OS (16.7 v 41.4 months, p < 0.001). There was induction of p53 expression in MGUS and SMM with concurrent induction of APAF1, p21 and MDM2 whereas loss of this pattern was frequent in MM (45% in new MM and 60% in relapse MM compared to 15% in MGUS/SMM (p = 0.03)). Conclusions: p53 mutations are relatively rare in newly diagnosed MM patients but portend a short survival. However, functional abnormalities of p53 are prevalent and may be important in progression from MGUS/SMM to MM. [Table: see text]

Abstract
7621 Background: Thalidomide (Thal) in combination with dexamethasone (Dex) is an effective therapy for myeloma (MM). Though initially evaluated in MM because of its anti-angiogenic properties, it is not clear how much this contribute to its anti-MM effects. We examined whether the degree of angiogenesis influences response to Thal + Dex, as well as effect of therapy on marrow angiogenesis. We also examined whether expression of angiogenic cytokines by MM cells affect response to therapy. Methods: A total of 207 pts with newly diagnosed MM were randomized on the ECOG phase III trial (E1A00) to either Thal-Dex or Dex alone. Bone marrow microvessel density (MVD) was determined on 88 pts at diagnosis and at 4 mos after therapy in 25 pts. Expression of fibroblast growth factor (FGF) and vascular endothelial growth factor (VEGF) by MM cells was determined by RTPCR on 60 pts at diagnosis and on 22 pts at 4 mos. In addition, the percentage of marrow PCs in apoptosis was determined at diagnosis and 4 mos in 43 pts. A decrease in the serum M protein by 50% or in its absence, a decrease in urine M protein by 50% was considered a response. Results: The median BM MVD at diagnosis was 33 (3–118), and was similar in the pts responding to therapy (36.4) and in the non responders (45.4). We also separately looked at those receiving the combination vs. Dex alone, and did not find any correlation. The expression of FGF and VEGF in the PCs did not predict response to therapy with either the combination or Dex. Among the 17 responding pts, MVD decreased by a mean of 12 compared to an increase in the mean MVD of 3 among the non responders (P = NS). There was no significant correlation between the level of FGF or VEGF expression and the marrow MVD. There was no correlation between the percentage of myeloma cells in apoptosis at baseline and response to therapy. Conclusion: While the anti-angiogenic activity of Thal may play a role in its anti-myeloma effect, baseline MVD or tumor cell expression of angiogenic cytokines do not predict resistance or response to Thal-Dex or Dex alone. The findings here confirm previous observations that marrow angiogenesis is not related to the degree of secretion of angiogenic cytokines by individual cells, but rather the cumulative effect of the tumor mass. No significant financial relationships to disclose.

Abstract
PURPOSE To determine if thalidomide plus dexamethasone yields superior response rates compared with dexamethasone alone as induction therapy for newly diagnosed multiple myeloma. PATIENTS AND METHODS Patients were randomly assigned to receive thalidomide plus dexamethasone or dexamethasone alone. Patients in arm A received thalidomide 200 mg orally for 4 weeks; dexamethasone was administered at a dose of 40 mg orally on days 1 to 4, 9 to 12, and 17 to 20. Cycles were repeated every 4 weeks. Patients in arm B received dexamethasone alone at the same schedule as in arm A. RESULTS Two hundred seven patients were enrolled: 103 were randomly assigned to thalidomide plus dexamethasone and 104 were randomly assigned to dexamethasone alone; eight patients were ineligible. The response rate with thalidomide plus dexamethasone was significantly higher than with dexamethasone alone (63% v 41%, respectively; P = .0017). The response rate allowing for use of serum monoclonal protein levels when a measurable urine monoclonal protein was unavailable at follow-up was 72% v 50%, respectively. The incidence rates of grade 3 or higher deep vein thrombosis (DVT), rash, bradycardia, neuropathy, and any grade 4 to 5 toxicity in the first 4 months were significantly higher with thalidomide plus dexamethasone compared with dexamethasone alone (45% v 21%, respectively; P < .001). DVT was more frequent in arm A than in arm B (17% v 3%); grade 3 or higher peripheral neuropathy was also more frequent (7% v 4%, respectively). CONCLUSION Thalidomide plus dexamethasone demonstrates significantly superior response rates in newly diagnosed myeloma compared with dexamethasone alone. However, this must be balanced against the greater toxicity seen with the combination.

Abstract
Hyperdiploid and non-hyperdiploid multiple myeloma represents distinct biological entities characterized by different patterns of genetic changes. We sought to determine whether ploidy category (non-hyperdiploid versus hyperdiploid) remains stable over time from diagnosis to progression. Of the 43 patients studied (39 by flow cytometry DNA index and 4 by a FISH-based index), only five (12%) altered their ploidy status at progression. In three of these patients, the change may possibly be attributable to technical artifacts because of the low absolute change in DNA index. For those who retain their ploidy subtypes, the DNA index change minimally (3.75+/-4.87%). It would appear that the initiating genetic events underlying hyperdiploid and non-hyperdiploid MM that marks them out as distinct entities continue to dominate and persist during disease evolution and progression.

Abstract
Two major genetic categories of multiple myeloma (MM) exist. Hyperdiploid MM (48 to 74 chromosomes, median 53 chromosomes) is associated with trisomies especially of chromosomes 3, 7, 9, 11, 15, and 19, whereas the nonhyperdiploid (< 48 chromosomes or more than 74 chromosomes) MM is associated with primary translocations such as t(11;14), t(4;14), and t(14;16). Whether this dichotomy exists in monoclonal gammopathy of undetermined significance (MGUS) is uncertain due to limitations of current methods in the study of ploidy. This is especially true in MGUS where the number of clonal plasma cells is small. In this study, we derived a fluorescent in situ hybridization (FISH)-based trisomy index from pooled cytogenetic data (karyotype analysis) from 2 large cohorts of patients with MM with abnormal karyotype, and then validated it in 2 independent cohorts of patients who had known ploidy status either by karyotyping or DNA content measurement using flow cytometry. Using the criteria of 2 or more trisomies from a 3-chromosome combination, hyperdiploid myeloma can be detected with high specificity. Applying this index on 28 patients with smoldering multiple myeloma (SMM) or MGUS (11 SMM, 17 MGUS) who had normal karyotype, 11 cases of hyperdiploid SMM/MGUS were detected. This percentage (40%) is remarkably similar to the percentage of hyperdiploid MM reported in the literature, suggesting that hyperdiploid MM may originate early during disease evolution.

Abstract
PURPOSE To determine the long-term prognosis of patients who develop a local recurrence (LR) after conservative surgery (CS) and radiation therapy (RT) for early-stage invasive breast cancer. METHODS AND MATERIALS Between 1970 and 1987, 2102 patients with clinical Stage I-II breast cancer were treated with CS+RT. LR was defined as any recurrence within the ipsilateral breast with or without simultaneous regional nodal or distant metastasis. Patients were at risk for a LR until the first of distant metastases, second nonbreast malignancy, or death (DF/S/D). The final study population comprised 341 patients with LR. The median time to LR was 72 months. The median follow-up time after LR was 85 months. A proportional hazards model of time from LR to DF/S/D was done to investigate the influence of factors at initial diagnosis and at LR on subsequent outcome. RESULTS The actuarial freedom from DF/S/D 5 years after LR was 65% and the survival was 81%. Variables significantly associated with time to DF/S/D were: LR histology (invasive vs. ductal carcinoma in situ, hazard ratio [HR] = 4.1, p < 0.0001); local therapy for LR (none vs. mastectomy or unknown, HR = 3.2, p < 0.0001; and CS +/- RT vs. mastectomy or unknown, HR = 2.0, p = 0.02); time to LR (< or =2 years vs. >5 years, HR = 2.6, p < 0.0001; and 2-5 years vs. >5 years, HR = 1.8, p = 0.006); and age at initial diagnosis (> or =60 vs. <60, HR = 1.6, p = 0.01). CONCLUSIONS Many patients with LR after CS+RT have prolonged distant disease-free survival, particularly those able to be treated with mastectomy. Patients with a noninvasive LR, longer interval to LR, or age <60 had a longer time to distant failure, second malignancy, or death than other patients.

Abstract
Waldenström macroglobulinemia (WM) is a low-grade lymphoplasmacytic lymphoma that strongly expresses CD20 on the cell surface. This study was undertaken to determine the response rate of patients with untreated or previously treated WM to the monoclonal antibody rituximab, which is directed against CD20+ expressed by B-cell lymphomas. Thirty-four untreated and thirty-five previously treated patients received rituximab 375 mg/m2 weekly for 4 consecutive weeks by intravenous infusion on days 1, 8, 15, and 22. Sixty-nine patients were evaluable for response; 19 (27.5%) achieved an objective response and 17 (24.6%) achieved a minor response. The overall response rate was 52.2% (90% CI [41.6%, 62.6%]). Of previously untreated patients 35.3% vs. 20% of previously treated patients achieved an objective response. Median response duration was not significantly different between previously untreated (27 months) and previously treated patients (not reached, P = 0.8). Rituximab produced objective or minor responses in 52.2% of patients and is an active agent in the treatment of WM. Grade 4 toxicity was seen in 11%.

Abstract
OBJECTIVES To determine the progression-free survival at 12 weeks, to evaluate the toxic effects, and to analyze the biological activity of thalidomide in patients with relapsed multiple myeloma (MM) after high-dose chemotherapy and stem cell transplantation. PATIENTS AND METHODS From 1999 to 2001, we performed a multicenter prospective phase 2 study in patients with MM that relapsed after high-dose chemotherapy and stem cell transplantation to evaluate the efficacy of oral thalidomide, with dose escalation from 200 to 600 mg/d over 12 weeks and a subsequent maintenance phase of 200 mg/d for up to 1 year. Outcome was correlated with serum and plasma levels of vascular endothelial growth factor and serum levels of tumor necrosis factor alpha, soluble intercellular adhesion molecule 1, interferon gamma, interleukin (IL) 2, and IL-6 during treatment. RESULTS Thirty patients were treated (19 men and 11 women; median age, 58 years). The median number of prior therapies was 5, and the median duration from diagnosis of MM to study enrollment was 4.3 years. The 12-week progression-free survival rate was 67% (95% confidence interval [CI], 48%-86%). The observed response rate (partial response plus minor response) was 43% (95% CI, 28%-60%) with a median duration of 6 months. Attributable toxicities included constipation, fatigue, rash, and neuropathy, which was dose limiting in 8 patients (27%). Dose escalation from 200 to 600 mg/d was achieved in 50% of patients. Although responses were observed with lower doses, possibly eliminating the need to escalate the dose, responses were also seen in patients who completed the dose escalation. Some patients had disease progression while receiving the maintenance dose of 200 mg/d. Analysis of biomarker assays did not identify any biomarker associated with greater response, but a significant increase in levels of soluble intercellular adhesion molecule 1, IL-2, and interferon gamma was seen with thalidomide therapy. CONCLUSION The optimal thalidomide dose varies, and adverse effects can be dose limiting. The dose of thalidomide therapy should be based on the individual patient to ensure that it is well tolerated and that a response is achieved.

Abstract
Stem cell transplantation was introduced as a new therapeutic modality for amyloidosis. The purpose of the current study was to determine the feasibility and toxicity of stem cell transplantation for amyloidosis in a cooperative group setting in which most participating institutions would have limited experience in managing the disorder. A total of 30 patients with biopsy-proven amyloidosis shown to be immunoglobulin light-chain type were enrolled on this trial. The protocol required mobilization of a minimum of 6 x 10(8) mononuclear cells/kg or 5 x 10(6) CD34(+) cells/kg ideal body weight. These targets had to be achieved within seven collections. Patients with advanced hepatic, renal, or cardiac failure were excluded. End points included objective response rate and overall survival. The secondary end point of the protocol was nonhematologic toxicity. Accrual to the study was faster than expected. The overall response rate (hematologic and organ) was 64%, with three treatment-related deaths. Another patient died before day 30 of sudden cardiac death not treatment related. The median follow-up of surviving patients is 30.3 months. Median survival has not been reached. Stem cell transplantation for selected patients with amyloidosis is feasible in a cooperative group setting. A multicenter phase 3 trial of high-dose therapy is indicated.

Abstract
Despite recent interest on the part of advocates and researchers of oncology clinical trials in sharing study results, participants in these trials are not routinely informed about the results. We identified oncology physicians and nurses through the Cancer and Leukemia Group B database and surveyed them about sharing clinical trial results with participants. Of 1977 eligible members, 796 (40.3%) responded to the mailed survey, 497 (62.4%) of whom reported that they offer trial results to participants less than one-fifth of the time. A total of 576 (72.4%) of responders believed that most patients want to know the results of studies, and 634 (79.7%) of responders expressed willingness to offer results to most study participants in the future, believing that most patients want to know trial results and that routinely offering results would not have a negative effect on patients. Concerns of some responders about routinely offering trial results included negative emotional effect on patients, patient difficulty understanding the information, and resources required to offer the results. Of concern, 16.2% (129/796) of responders believed an obligation to offer results to study participants would make them less likely to enroll patients on studies. Future studies should consider sharing trial results with patients and evaluating the process and its effect on both patients and clinicians.

Abstract
BACKGROUND The goal of the current study was to characterize the initial upsurge in immunoglobulin M (IgM) levels after treatment with rituximab in patients with Waldenstrom macroglobulinemia (WM). METHODS As part of a Phase II Eastern Cooperative Oncology Group study, 72 patients were treated with rituximab (375 mg/m(2) weekly for 4 weeks) between April 2000 and January 2002. IgM levels in these patients were measured at five separate time points so that any temporal changes that occurred could be characterized. RESULTS Of the 54 patients for whom the relevant IgM measurements were available, 29 (54%) experienced an increase in IgM levels between baseline and the first scheduled postbaseline time point. At 2 months, 13 of 22 evaluable patients (59%) continued to have elevated IgM levels, and at 4 months, elevated IgM levels persisted in 4 of 15 evaluable patients (27%). Overall, a nonlinear trend characterized by an initial increase in IgM levels followed by a decrease in these levels was observed (P < 0.0001). CONCLUSIONS Treating physicians should be aware that an IgM 'flare' may occur in up to 54% of patients treated with rituximab; however, most of these patients experience a decrease in IgM levels within 4 months after the initiation of therapy. Therefore, patients should not be discouraged from continuing to receive this potentially effective therapeutic agent, as responses to rituximab may develop slowly. Longer follow-up will reveal whether patients who experience an upsurge in IgM levels have poorer overall survival or shorter times to progression compared with patients who do not experience this IgM flare. Factors predicting an initial increase in IgM levels could not be identified.

Abstract
Aneuploid is ubiquitous in multiple myeloma (MM), and 4 cytogenetic subcategories are recognized: hypodiploid (associated with a shorter survival), pseudodiploid, hyperdiploid, and near-tetraploid MM. The hypodiploid, pseudodiploid, and near-tetraploid karyotypes can be referred to as the nonhyperdiploid MM. Immunoglobulin heavy-chain (IgH) translocations are seen in 60% of patients. We studied the relation between aneuploidy and IgH translocations in MM. Eighty patients with MM and abnormal metaphases were studied by means of interphase fluorescent in situ hybridization (FISH) to detect IgH translocations. We also studied a second cohort of 199 patients (Eastern Cooperative Oncology Group [ECOG]) for IgH translocations, chromosome 13 monosomy/deletions (Delta13), and ploidy by DNA content. Mayo Clinic patients with abnormal karyotypes and FISH-detected IgH translocation were more likely to be nonhyperdiploid (89% versus 39%, P <.0001). Remarkably, 88% of tested patients with hypodiploidy (16 of 18) and 90% of tested patients with tetraploidy (9 of 10) had an IgH translocation. ECOG patients with IgH translocations were more likely to have nonhyperdiploid MM by DNA content (68% versus 21%, P <.001). This association was seen predominantly in patients with recurrent chromosome partners to the IgH translocation (11q13, 4p16, and 16q23). The classification of MM into hyperdiploidy and nonhyperdiploidy is dictated largely by the recurrent (primary) IgH translocations in the latter.

Abstract
BACKGROUND Docetaxel has activity against multiple malignancies. In a previous ECOG study of untreated patients with multiple myeloma, paclitaxel was found to have mild activity, but had excessive toxicity. Docetaxel was evaluated in patients with relapsing or refractory multiple myeloma. METHOD Well-documented patients with relapsing or refractory multiple myeloma, who had received no more than two prior combination chemotherapy regimens, were treated with docetaxel 75 mgm(-2) intravenously over 1h every 3 weeks. Patients were evaluated after two and four cycles of treatment. Standard ECOG criteria were used to evaluate for response and toxicity. RESULTS The study accrued 31 patients with 28 eligible for response and 30 for toxicity analysis. No objective responses (partial or complete) were found. One patient died due to pneumonia. The majority of patients (80%) developed grade 3-4 granulocytopenia and 23% experienced grade 3-4 thrombocytopenia. The median number of cycles was three. The median survival was 9.9 months. CONCLUSION Docetaxel was inactive in patients with relapsing or refractory multiple myeloma. In addition, at 75 mgm(-2) every 3 weeks, there was extensive hematological toxicity. It is unlikely that a change in dose or a different schedule would significantly improve response, limit toxicity, and improve survival in patients with multiple myeloma.

Abstract
Nonrandom recurrent chromosomal abnormalities are ubiquitous in multiple myeloma (MM) and include, among others, translocations of the immunoglobulin heavy chain locus (IgH). IgH translocations in MM result in the up-regulation of oncogenes, and include more commonly t(11;14)(q13;q32), t(4;14)(p16;q32), and t(14;16)(q32;q23). Based on the recurrent nature of these translocations and their finding since the early stages of the plasma cell (PC) disorders, we hypothesized that they would confer biologic and clinical variability. In addition, deletions of 13q14 and 17p13 have also been associated with a shortened survival. We used cytoplasmic Ig-enhanced interphase fluorescent in situ hybridization to detect deletions (13q14 and 17p13.1), and translocations involving IgH in 351 patients treated with conventional chemotherapy entered into the Eastern Cooperative Oncology Group clinical trial E9486/9487. Translocations were frequently unbalanced with loss of one of the derivative chromosomes. The presence of t(4; 14)(p16;q32) (n = 42; 26 vs 45 months, P <.001), t(14;16)(q32;q23) (n = 15; 16 vs 41 months, P =.003), - 17p13 (n = 37; 23 vs 44 months, P =.005), and - 13q14 (n = 176; 35 vs 51 months, P =.028) were associated with shorter survival. A stratification of patients into 3 distinct categories allowed for prognostication: poor prognosis group (t(4;14)(p16;q32), t(14; 16)(q32;q23), and - 17p13), intermediate prognosis (- 13q14), and good prognosis group (all others), with median survivals of 24.7, 42.3, and 50.5 months, respectively (P <.001). This molecular cytogenetic classification identifies patients into poor, intermediate, and good risk categories. More importantly it provides further compelling evidence that MM is composed of subgroups of patients categorized according to their underlying genomic aberrations.
