Feasibility and Toxicity of Chemoembolization for Children With Liver Tumors
Authors: Malogolowkin Marcio H. , Stanley Philip , Steele David A. , Ortega Jorge A.
Published: February 2017

PURPOSE: To determine the feasibility, toxicity, and efficacy of hepatic arterial chemoembolization (HACE) in pediatric patients with refractory primary malignancies of the liver.

PATIENTS AND METHODS: Six patients with hepatoblastoma (HB), three with hepatocellular carcinoma (HCC), and two with undifferentiated sarcoma of the liver were treated with HACE every 2 to 4 weeks until their tumors became surgically resectable or they showed signs of disease progression. All but one newly diagnosed patient with HCC had previously received systemic chemotherapy.

RESULTS: All patients with HB and HCC responded to HACE, as measured by imaging studies and alpha-fetoprotein levels. Surgical resection (complete or microscopic residual disease) was feasible in five of 11 patients, and three patients remain alive with no evidence of disease. Elevated liver transaminase and bilirubin levels were seen after each one of the 46 courses of HACE. Other toxicities included fever, pain, nausea, vomiting, and transient coagulopathy.

CONCLUSION: HACE is feasible, well tolerated, and effective in inducing surgical resectability of primary hepatic tumors in children.

Published: February 2017

PURPOSE: To evaluate the usefulness of fluorescence in situ hybridization (FISH) on peripheral-blood specimens to evaluate the cytogenetic response to treatment in patients with chronic myeloid leukemia (CML).

PATIENTS AND METHODS: In a first attempt, we analyzed 62 bone marrow specimens using interphase FISH and compared the results with those of conventional cytogenetics. In a second step, we analyzed 60 paired sets of bone marrow and peripheral-blood specimens with interphase FISH.

RESULTS: The results of interphase FISH agreed with conventional cytogenetics on bone marrow for most patients, and only minor differences were found (r = .98). The comparison of interphase FISH on bone marrow versus peripheral-blood specimens showed a strong correlation between these two specimen sources (r = .97).

CONCLUSION: Our results confirmed that FISH is a sensitive technique for the evaluation of response to treatment in patients with CML. Moreover, our study suggests that follow-up of cytogenetic response to therapy can be evaluated on peripheral-blood specimens, thus enabling an easier and more frequent evaluation of patients. The next step will be to evaluate this technique in a large prospective trial to define the prognostic value of complete remissions evaluated by FISH.
Role of Isolated Locoregional Recurrence of Breast Cancer: Results of Four Prospective Studies
Authors: Schmoor Claudia , Sauerbrei Willi , Bastert Gunter , Schumacher Martin ,   for the German Breast Cancer Study Group
Published: February 2017

PURPOSE: We evaluated the effect on future prognosis of an isolated locoregional recurrence (ILRR) after the primary diagnosis of breast cancer. Using data from four prospective studies of the German Breast Cancer Study Group, we investigated factors influencing prognosis after ILRR and defined a simple classification of patients into groups with different prognoses.

PATIENTS AND METHODS: From 1983 to 1989, 2,746 patients were recruited into four studies comparing different treatments in primary breast cancer. After a median follow-up time of 8 years, 337 patients developed an ILRR as the first event. The influence of ILRRs on disease progression was examined. The effects of different prognostic factors on progression-free survival (PFS) and overall survival after ILRR were analyzed after a median follow-up time of 4.5 years.

RESULTS: ILRRs increased the risk with respect to distant recurrence and death. After ILRR, 185 events occurred with respect to the PFS end point, and 171 patients died. Primary nodal status, tumor grade, estrogen receptor status of the primary tumor, and length of the disease-free interval (DFI) until the time of the ILRR had a significant prognostic impact.

CONCLUSION: Determinants of prognosis after the ILRR should be taken into account for designing future risk-adapted clinical studies for these patients. Risk strata can be defined by a simple classification scheme based on primary nodal status and DFI.
Drug Interactions in Palliative Care
Authors: Bernard Stephen A. , Bruera Eduardo
Published: February 2017

PURPOSE: This review of drug interactions in palliative care examines the relevant literature in this area and summarizes the information on interactions of drugs, nutrients, and natural products that are used in the palliative care setting. Particular emphasis is placed on describing the newer information on the cytochrome P450 (CYP) system and the interactions of opioids, antidepressants, and the antitussive, dextromethorphan.

METHODS: We performed a search of the MEDLINE database of the time period from 1966 until April 1998, using medical subject headings such as the names of selective serotonin reuptake inhibitors and other relevant medications in palliative care. Literature reviewed included both human and animal articles as well as non-English literature. Bibliographies of these articles and the personal libraries of several palliative care specialists were reviewed. Software developed by The Medical Letter—The Drug Interaction Program was also used.

RESULTS: Drug interactions can be categorized in several ways. Drug-drug interactions are the most well known and can be kinetic, dynamic, or pharmaceutical. Pharmacokinetic interactions can involve CYP 2D6, which acts on drugs such as codeine and is responsible for its conversion to morphine. Poor metabolizers, either genotypic or due to phenocopying, are at risk for undertreatment if not recognized. Pharmacodynamic interactions with dextromethorphan may produce serotonin syndrome.

CONCLUSION: Drug interactions are important in palliative care as in other aspects of medicine. These interactions are similar to those seen in other areas of medical care but have significant consequences in pain management. Failure to recognize these interactions can lead to either overdosing or undertreatment.
Early Detection of Relapse by Hypermetaphase Fluorescence In Situ Hybridization After Allogeneic Bone Marrow Transplantation for Chronic Myeloid Leukemia

Published: February 2017

PURPOSE: Standard G-band cytogenetic analysis (CG) provides information on approximately 25 metaphases for monitoring the presence of Philadelphia chromosome positive (Ph+) cells in chronic myelogenous leukemia (CML) patients, making the detection of a low frequency of Ph+ cells problematic. The purpose of this study was to improve the detection of a low frequency of Ph+ cells.

PATIENTS AND METHODS: We combined fluorescence in situ hybridization (FISH) with long-term colcemid exposure, capturing several hundred metaphases in bone marrow cultures (hypermetaphase FISH [HMF]). Using probes that identify Ph+ cells, HMF was compared with CG analysis in the follow-up evaluations of 51 patients with CML at various time points after allogeneic bone marrow transplant (BMT).

RESULTS: Thirty-five patients never showed the presence of Ph+ cells by either method. In four patients, high frequencies of Ph+ cells were detected by both methods. In the remaining 12 patients, Ph+ cells were detected by HMF at time points after BMT when they were not detected by CG. In seven of the 12 patients, low but statistically significant frequencies of Ph+ cells (0.37% to 5.20%) were detected 3 months or later after BMT, and when no intervention was initiated, all seven patients later relapsed. Based on those data, an eighth patient with mixed chimerism and a similar HMF-detected Ph+ frequency (1.8% at 27 months after BMT) was reinfused with donor lymphocytes and achieved remission with 0% Ph+ cells studied by HMF (up to 50 months after BMT). Ph+ cells detected by HMF but not by CG less than 3 months after BMT disappeared on later examination in two of four patients. After detection of Ph+ cells by HMF only, the median time to cytogenetic progression (detection of Ph+ cells by CG) was 101 days.

CONCLUSION: The results demonstrate the ability of HMF to detect low but clinically relevant levels of leukemic cells not detected by CG in transplant patients. The data indicate that HMF can detect low levels of Ph+ cells before standard cytogenetics at a time that may be useful in monitoring disease status and planning clinical interventions.
Alpha Hemolytic Streptococcal Infection During Intensive Treatment for Acute Myeloid Leukemia: A Report From the Children’s Cancer Group Study CCG-2891
Authors: Gamis Alan S. , Howells William B. , DeSwarte-Wallace Joetta , Feusner James H. , Buckley Jonathan D. , Woods William G.
Published: February 2017

PURPOSE: Past reports indicate that alpha hemolytic streptococcal (AHS) organisms are a common cause of infection among acute myeloid leukemia (AML) patients. This study was intended to ascertain the population incidence and rate (infections per 100 patient-days of treatment) of AHS and to identify associated risk factors.

PATIENTS AND METHODS: Patients (n = 874 with 151,350 days of risk) enrolled on the Children’s Cancer Group (CCG) protocol for newly diagnosed AML, CCG-2891, which randomly assigned intensity of induction and intensification, were prospectively evaluated for infectious complications.

RESULTS: AHS occurred in 21% of patients, was primarily blood borne (86%), made up 21% of bacteremic infections, and had a recurrent incidence of 31% during subsequent therapy. AHS was more often life-threatening (59%) than other infections (41%) (P = .001). AHS rates increased with age less than 10 years (odds ratio [OR], 2.0; P = .007), intensively timed induction (OR, 1.8 to 1.9; P = .02), and high-dose cytarabine intensification (OR, 3.7; P < .0001). Among all courses, the greatest incidence (19%) and rate (0.41) were associated with the use of high-dose cytarabine. Gastrointestinal toxicity correlated significantly with AHS bacteremia (P < .01). Infection with AHS resulted in increased hospital days (P = .0001). Only among bone marrow transplant patients were overall survival (OR, 2.8; P = .0001) and disease-free survival (OR, 2.1; P = .008) decreased after AHS bacteremia.

CONCLUSION: This study, the first to prospectively examine AHS incidence among uniformly treated patients in multiple institutions, established that as the intensity of AML therapy has increased, so has the rate of AHS. Young children, those with previous AHS bacteremias, and those receiving high-dose cytarabine are at particularly high risk of AHS bacteremia.
Loss of Heterozygosity at 1p36 Independently Predicts for Disease Progression But Not Decreased Overall Survival Probability in Neuroblastoma Patients: A Children’s Cancer Group Study
Authors: Maris John M. , Weiss Matthew J. , Guo Chun , Gerbing Robert B. , Stram Daniel O. , White Peter S. , Hogarty Michael D. , Sulman Erik P. , Thompson Patricia M. , Lukens John N. , Matthay Katherine K. , Seeger Robert C. , Brodeur Garrett M.
Published: February 2017

PURPOSE: To determine the independent prognostic significance of 1p36 loss of heterozygosity (LOH) in a representative group of neuroblastoma patients.

PATIENTS AND METHODS: Diagnostic tumor specimens from 238 patients registered onto the most recent Children’s Cancer Group phase III clinical trials were assayed for LOH with 13 microsatellite polymorphic markers spanning chromosome band 1p36. Allelic status at 1p36 was correlated with other prognostic variables and disease outcome.

RESULTS: LOH at 1p36 was detected in 83 (35%) of 238 neuroblastomas. There was a correlation of 1p36 LOH with age at diagnosis greater than 1 year (P = .026), metastatic disease (P < .001), elevated serum ferritin level (P < .001), unfavorable histopathology (P < .001), and MYCN oncogene amplification (P < .001). LOH at 1p36 was associated with decreased event-free survival (EFS) and overall survival (OS) probabilities (P < .0001). For the 180 cases with single-copy MYCN, 1p36 LOH status was highly correlated with decreased EFS (P = .0002) but not OS (P = .1212). Entering 1p36 LOH into a multivariate regression model suggested a trend toward an independent association with decreased EFS (P = .0558) but not with decreased OS (P = .3687). Furthermore, allelic status at 1p36 was the only prognostic variable that was significantly associated with decreased EFS in low-risk neuroblastoma patients (P = .0148).

CONCLUSION: LOH at 1p36 is independently associated with decreased EFS, but not OS, in neuroblastoma patients. Determination of 1p36 allelic status may be useful for predicting which neuroblastoma patients with otherwise favorable clinical and biologic features are more likely to have disease progression.

Authors: Herfarth Klaus K. , Debus Jürgen , Lohr Frank , Bahner Malte L. , Rhein Bernhard , Fritz Peter , Höss Angelika , Schlegel Wolfgang , Wannenmacher Michael F.
Published: February 2017

PURPOSE: To investigate the feasibility and the clinical response of a stereotactic single-dose radiation treatment for liver tumors.

PATIENTS AND METHODS: Between April 1997 and September 1999, a stereotactic single-dose radiation treatment of 60 liver tumors (four primary tumors, 56 metastases) in 37 patients was performed. Patients were positioned in an individually shaped vacuum pillow. The applied dose was escalated from 14 to 26 Gy (reference point), with the 80% isodose surrounding the planning target volume. Median tumor size was 10 cm3 (range, 1 to 132 cm3). The morbidity, clinical outcome, laboratory findings, and response as seen on computed tomography (CT) scan were evaluated.

RESULTS: Follow-up data could be obtained from 55 treated tumors (35 patients). The median follow-up period was 5.7 months (range, 1.0 to 26.1 months; mean, 9.5 months). The treatment was well tolerated by all patients. There were no major side effects. Fifty-four (98%) of 55 tumors were locally controlled after 6 weeks at the initial follow-up based on the CT findings (22 cases of stable disease, 28 partial responses, and four complete responses). After a dose-escalating and learning phase, the actuarial local tumor control rate was 81% at 18 months after therapy. A total of 12 local failures were observed during follow-up. So far, the longest local tumor control is 26.1 months.

CONCLUSION: Stereotactic single-dose radiation therapy is a feasible method for the treatment of singular inoperable liver metastases with the potential of a high local tumor control rate and low morbidity.
Treatment of Orbital Rhabdomyosarcoma: Survival and Late Effects of Treatment—Results of an International Workshop
Authors: Oberlin Odile , Rey Annie , Anderson James , Carli Modesto , Raney R. Beverley , Treuner Joern , Stevens Michael C.G. ,   the Intergroup Rhabdomyosarcoma Study Group,,   the Italian Cooperative Soft Tissue Sarcoma Group, and,   the German Collaborative Soft Tissue Sarcoma Group
Published: February 2017

PURPOSE: Orbital rhabdomyosarcoma (RMS) historically has been associated with an excellent survival rate. The majority of patients are cured with the use of both chemotherapy and radiation therapy, but a significant number experience important late sequelae of treatment. In an attempt to determine optimal therapy in relation both to cure and to sequelae, the experience of the four international collaborative groups (Intergroup Rhabdomyosarcoma Study Group [IRSG], International Society of Paediatric Oncology [SIOP] Sarcoma Committee, German Collaborative Soft Tissue Sarcoma Group [CWS], and Italian Cooperative Soft Tissue Sarcoma Group [ICG] studies) was shared at an international workshop.

PATIENTS AND METHODS: A total of 306 eligible patients were identified from group records (186 from IRS, 43 from SIOP MMT, 40 from CWS, and 37 from ICG). Median age was 6.8 years, and median follow-up was 6.5 years. Eighty percent of patients received radiation therapy (RT) as part of primary therapy, but there were significant differences in the use of RT between the individual groups (93% in IRSG, 76% in ICG, and 70% in CWS, but only 37% in the SIOP MMT group).

RESULTS: At 10 years, event-free and overall survival for the whole cohort were 77% (range, 71% to 81%) and 87% (range, 82% to 92%), respectively. There was no difference in overall survival between the collaborative groups regardless of differences in the use of initial RT. In total, 34 (12%) of 273 survivors had not received RT, although this varied between the different groups (41% in the SIOP MMT group, 20% in CWS, 7% in ICG, and 6% in IRSG). There was no difference in overall survival for the whole cohort regardless of whether radiotherapy was used as part of initial therapy (86% at 10 years for both).

CONCLUSION: These data suggest that a subset of patients with orbital RMS can be cured without systematic local therapy, although the total burden of treatment (primary therapy and treatment for relapse) must be taken into account when assessing the implications for late sequelae.
Effect of Endocrine Treatment on Sexuality in Premenopausal Breast Cancer Patients: A Prospective Randomized Study
Authors: Berglund Gunilla , Nystedt Marianne , Bolund Christina , Sjödén Per-Olow , Rutquist Lars-Erik
Published: February 2017

PURPOSE: To study the sexual effects of the 2-year adjuvant goserelin (Zoladex [Zeneca AB, Södertälje, Sweden]) alone, tamoxifen alone, and Zoladex and tamoxifen in combination (ZT) versus no adjuvant endocrine therapy among premenopausal breast cancer patients with or without chemotherapy in a controlled clinical trial (a European multicenter trial: Zoladex in Premenopausal Breast Cancer Patients).

PATIENTS AND METHODS: This prospective study examined several aspects of sexuality through the use of self-administered questionnaires, which were completed by patients at seven points of assessment for 3 years after randomization.

RESULTS: Patients treated with chemotherapy had a higher level of sexual dysfunction than did patients who received no systemic treatment. The addition of endocrine treatment did not alter this result. In contrast, among patients who did not receive chemotherapy, Zoladex and ZT produced a significantly higher level of dysfunction from 1 to 2 years after inclusion, as compared with those who received no endocrine treatment. Tamoxifen alone did not produce side effects. After termination of endocrine treatment, sexual dysfunction began to diminish. Those with chemotherapy had high and frequently increasing levels of dysfunction even after 2 to 3 years of independent of endocrine treatment. Zoladex had a negative effect on sexual fear, which was reduced by the addition of tamoxifen.

CONCLUSION: Zoladex increased sexual dysfunction during treatment among patients without chemotherapy, but the disturbances of sexual functioning were reversible. The use of adjuvant chemotherapy was associated with continued sexual problems, even at 3 years after randomization.
Psychosocial Characteristics of Individuals With Non–Stage IV Melanoma

Published: February 2017

PURPOSE: Melanoma is the fastest growing solid tumor among men and women and accounts for 79% of skin cancer–related deaths. Research has identified that distress is frequently associated with a diagnosis of cancer and may slow treatment-seeking and recovery, increasing morbidity and even mortality through faster disease course. Given that the 5-year survival rates for individuals with melanoma are determined primarily by the depth and extent of spread, distress that interferes with seeking treatment has the potential to be life-threatening.

PATIENTS AND METHODS: The current study was designed to identify levels of distress present in individuals seeking treatment at a large, Midwestern, multidisciplinary melanoma clinic. It also focused on determining the quality of life, level of anxiety, and coping strategies used by individuals with melanoma before treatment. Given that the course of treatment and outcome for patients with stage IV disease is vastly different from that of patients with stages I to III disease, they were excluded from the study.

RESULTS: Results indicated that most individuals who are presenting to a melanoma clinic do not report a clinically significant level of distress. However, there is some variability in this, with 29% of patients reporting moderate to high levels of distress. Moreover, analyses suggest that distressed individuals are more likely to use maladaptive coping strategies, such as escape-avoidance coping, and to have poorer quality of life.

CONCLUSION: Although most individuals do not present with significant levels of distress, a significant minority are distressed and rely more heavily on coping strategies that do not benefit them. Such individuals would likely benefit most from psychological intervention.
Phase I/II Trial of the Multidrug-Resistance Modulator Valspodar Combined With Cisplatin and Doxorubicin in Refractory Ovarian Cancer
Authors: Baekelandt Mark , Lehne Gustav , Tropé Claes G. , Szántó István , Pfeiffer Per , Gustavssson Bengt , Kristensen Gunnar B.
Published: February 2017

PURPOSE: To determine the maximum-tolerated dose (MTD) of doxorubicin when given in combination with cisplatin and the multidrug-resistance (MDR) modulator valspodar and the remission rate induced by this combination in patients with platinum- and anthracycline-resistant ovarian cancer.

PATIENTS AND METHODS: Fifty-nine patients who had failed prior platinum- and anthracycline-based chemotherapy were enrolled. During the dose-finding phase, patients received a loading dose of valspodar (1.5 or 2 mg/kg) via 2-hour intravenous (IV) infusion on day 1 and continuous IV infusion (CIVI) of valspodar (2, 4, or 10 mg/kg/d) over 3 days. Doxorubicin (starting from 20 up to 50 mg/m2) and cisplatin (50 mg/m2) were administered via 15- to 20-minute IV infusions on day 3. During the efficacy phase, patients received at least two treatment cycles unless toxicity was unacceptable, and responding patients and those with stable disease received four to six cycles.

RESULTS: All patients completed at least one cycle of combined treatment. The MTD of doxorubicin was determined to be 35 mg/m2 when administered with valspodar at 2 mg/kg loading dose and 10 mg/kg/d CIVI plus 50 mg/m2 cisplatin. At these doses, valspodar blood concentrations known to reverse MDR in vitro were reached in all patients. Valspodar was well tolerated at all dose levels. Dose-limiting toxicities of the combination were primarily hematologic and included febrile neutropenia and prolonged leucopenia. The addition of valspodar to the treatment did not worsen cisplatin-related toxicity. Among 33 patients treated at the MTD for doxorubicin, one (3%) had a complete response, and four (12%) had a partial response. An additional seven patients experienced a stabilization of their previously progressive disease. The survival rates at 6 and 12 months were 59% and 19%, respectively.

CONCLUSION: Valspodar can be safely coadministered with doxorubicin and cisplatin. Although the regimen used in this trial produced renewed responses in patients with heavily pretreated, refractory ovarian cancer, the value of valspodar in reversing resistance mediated by P-glycoprotein remains to be determined.

Published: February 2017

PURPOSE: To determine the relationship between multiple genetic features, tumor morphology, and prognosis in neuroblastoma.

PATIENTS AND METHODS: The genetic alterations and morphologic features that underpin three histopathologic risk classifications were analyzed in 108 neuroblastoma patients. Tumors were subdivided into four groups based on the three most frequent and prognostically significant genetic alterations (17q gain, 1p deletion, and MYCN amplification), and all other genetic, morphologic, and clinical data were analyzed with respect to these groups.

RESULTS: Our analyses identify three nonoverlapping tumor types with distinct genetic and morphologic features, defined here as types 1, 2, and 3. Type 1 tumors show none of the three significant genetic alterations and have good prognosis. Both type 2 (17q gain only or 17q gain and 1p del) and type 3 (17q gain, 1p del, and MYCN amplification) tumors progress. However, these tumor types are distinguished clinically by having significantly different median age at diagnosis and median progression-free survival (PFS). Multivariate analysis indicates that 17q gain is the only independent prognostic factor among all genetic, histopathologic, and clinical factors analyzed. Among histopathologic risk systems, the International Neuroblastoma Pathology Classification was the best predictor of PFS.

CONCLUSION: Our results indicate that specific combinations of genetic changes in neuroblastoma tumors contribute to distinct morphologic and clinical features. Furthermore, the identification of two genetically and morphologically distinct types of progressing tumors suggests that possibilities for different therapeutic regimens should be investigated.
Phase III Trial Comparing Two Dose Levels of Epirubicin Combined With Cyclophosphamide With Cyclophosphamide, Methotrexate, and Fluorouracil in Node-Positive Breast Cancer

Published: February 2017

PURPOSE: To compare a full-dose epirubicin-cyclophosphamide (HEC) regimen with classical cyclophosphamide, methotrexate, and fluorouracil (CMF) therapy and with a moderate-dose epirubicin-cyclophosphamide regimen (EC) in the adjuvant therapy of node-positive breast cancer.

PATIENTS AND METHODS: Node-positive breast cancer patients who were aged 70 years or younger were randomly allocated to one of the following treatments: CMF for six cycles (oral cyclophosphamide); EC for eight cycles (epirubicin 60 mg/m2, cyclophosphamide 500 mg/m2; day 1 every 3 weeks); and HEC for eight cycles (epirubicin 100 mg/m2, cyclophosphamide 830 mg/m2; day 1 every 3 weeks).

RESULTS: Two hundred fifty-five, 267, and 255 eligible patients were treated with CMF, EC, and HEC, respectively. Patient characteristics were well balanced among the three arms. One and three cases of congestive heart failure were reported in the EC and HEC arms, respectively. Three cases of acute myeloid leukemia were reported in the HEC arm. After 4 years of median follow-up, no statistically significant differences were observed between HEC and CMF (event-free survival [EFS]: hazards ratio [HR] = 0.96, 95% confidence interval [CI], 0.70 to 1.31, P = .80; distant-EFS: HR = 0.97, 95% CI, 0.70 to 1.34, P = .87; overall survival [OS]: HR = 0.97, 95% CI, 0.65 to 1.44, P = .87). HEC is more effective than EC (EFS: HR = 0.73, 95% CI, 0.54 to 0.99, P = .04; distant-EFS: HR = 0.75, 95% CI, 0.55 to 1.02, P = .06; OS HR = 0.69, 95% CI, 0.47 to 1.00, P = .05).

CONCLUSION: This three-arm study does not show an advantage in favor of an adequately dosed epirubicin-based regimen over classical CMF in the adjuvant therapy of node-positive pre- and postmenopausal women with breast cancer. Moreover, this study confirms that there is a dose-response curve for epirubicin in breast cancer adjuvant therapy.
Toxicity, Efficacy, and Pharmacology of Suramin in Adults With Recurrent High-Grade Gliomas
Authors: Grossman Stuart A. , Phuphanich Surasak , Lesser Glenn , Rozental Jack , Grochow Louise B. , Fisher Joy , Piantadosi Steven ,   for the New Approaches to Brain Tumor Therapy CNS Consortium
Published: February 2017

PURPOSE: To determine the toxicity, efficacy, and pharmacology of suramin in patients with recurrent or progressive recurrent high-grade gliomas.

PATIENTS AND METHODS: Fifty adults were to receive suramin. However, if no responses were seen in the first ten patients, the study was to be terminated. A total of 12 patients were enrolled onto this trial. Ten patients had glioblastoma multiforme, and 11 had received prior nitrosoureas.

RESULTS: Drug-related toxicities were modest and reversible. Three patients developed grade 3 to 4 neutropenia, constipation, diarrhea, or nausea. No CNS bleeding was observed. Median time to progression was 55 days (range, 17 to 242 days) and median survival was 191 days (range, 42 to 811 days). No partial or complete responses were seen at 12 weeks. However, the clinical outcome of three patients suggests that evidence of suramin activity may be delayed. One patient who “progressed” after 12 weeks of suramin had a subsequent marked reduction in tumor size and has maintained an excellent partial response for over 2 years without other therapy. Two others had disease stabilization and lived for 16 and 27 months. Pharmacokinetics from 11 patients revealed that all reached target suramin concentrations.

CONCLUSION: This study demonstrates that suramin is well tolerated by patients with recurrent high-grade gliomas and may have efficacy in this disease. Its pharmacology seems unaffected by anticonvulsants. As a result of this data, suramin and radiation are now being administered concurrently to patients with newly diagnosed glioblastoma multiforme, with survival as the primary outcome.

Published: February 2017

PURPOSE: To analyze the impact of pre- and posttransplantation factors on the outcome of allogeneic transplantation after nonmyeloablative conditioning regimens.

PATIENTS AND METHODS: Ninety-two allogeneic transplantations after nonmyeloablative preparative regimens were reported to the Société Française de Greffe de Moelle Registry registry. Initial diagnoses were lymphoid diseases (n = 22), myeloma (n = 14), acute leukemia and myelodysplasia (n = 41), chronic myelogenous leukemia (n = 12), and solid tumors (n = 3). Forty-six patients had previously received a transplant, and 49 had progressive disease before transplantation. Three types of conditioning regimens were used with fludarabine or antithymocyte globulins. Eighty-nine patients underwent transplantation, 60 from peripheral-blood progenitor cells. Eighty-six patients received graft-versus-host disease (GHVD) prophylaxis for a median duration of 53 days.

RESULTS: Seventy-nine patients engrafted, with 40 complete and 21 mixed chimerisms. The acute GHVD rate at 3 months was 50% ± 11%. Fifty-two patients achieved complete remission and 12, partial remission. At 18 months after transplantation, the overall survival (OS) and the transplant-related mortality (TRM) were 32% ± 12% and 38% ± 14%, respectively. Initial diagnosis and disease status before transplantation significantly influenced survival. Age and GHVD prophylaxis type significantly influenced TRM. We also showed an impact of GHVD prophylaxis duration on OS and TRM. In multivariate analysis, three factors remained of prognostic value on OS: initial diagnosis, disease status at transplantation, and GHVD prophylaxis duration.

CONCLUSION: This series shows encouraging results from nonmyeloablative conditioning regimens before allotransplantation and demonstrates the impact of some pre- and posttransplantation factors on outcome after transplantation.

Authors: Saylors Robert L. , Stine Kimo C. , Sullivan Jim , Kepner James L. , Wall Donna A. , Bernstein Mark L. , Harris Michael B. , Hayashi Robert , Vietti for the Pediatric Oncology Group Teresa J.
Published: February 2017

PURPOSE: To determine the response rate of the combination of cyclophosphamide and topotecan in pediatric patients with recurrent or refractory malignant solid tumors.

PATIENTS AND METHODS: A total of 91 pediatric patients, 83 of whom were fully assessable for response and toxicity, received cyclophosphamide (250 mg/m2/dose) followed by topotecan (0.75 mg/m2/dose), each given as a 30-minute infusion daily for 5 days. All patients received filgrastim (5 mcg/kg) daily until the absolute neutrophil count (ANC) was ≥ 1,500 μL after the time of the expected ANC nadir.

RESULTS: A total of 307 treatment courses were given to the 83 fully assessable patients. Responses (complete response plus partial response) were seen in rhabdomyosarcoma (10 of 15 patients), Ewing’s sarcoma (six of 17 patients), and neuroblastoma (six of 13 patients). Partial responses were seen in two of 18 patients with osteosarcoma and in one patient with a Sertoli-Leydig cell tumor. Twenty-three patients had either minor responses (n = 6) or stable disease (n = 17); the median number of courses administered to patients with partial or complete response was six (range, two to 13 courses), and the median administered to those with stable disease was three (range, one to 11 courses). The toxicity of the combination was limited principally to the hematopoietic system. Of 307 courses, 163 (53%) were associated with grade 3 or 4 neutropenia, 84 (27%) with grade 3 or 4 anemia, and 136 (44%) with grade 3 or 4 thrombocytopenia. Despite the severe myelosuppression, only 34 (11%) of 307 courses were associated with grade 3 or 4 infection. Nonhematopoietic toxicity of grades ≥ 3 was rare and consisted of nausea and vomiting (two courses), perirectal mucositis (one course), transaminase elevation (one course), and hematuria (two courses).

CONCLUSION: The combination of cyclophosphamide and topotecan is active in rhabdomyosarcoma, neuroblastoma, and Ewing’s sarcoma. Stabilization of disease was seen in osteosarcoma, although objective responses were rare in this disease. The therapy can be given with acceptable hematopoietic toxicity with the use of filgrastim support.

PURPOSE: To determine the prevalence of suspected disease in the mediastinum and internal mammary (IM) node chain by 18fluorodeoxyglucose (FDG) positron emission tomography (PET), compared with conventional staging by computed tomography (CT) in patients with recurrent or metastatic breast cancer.

PATIENTS AND METHODS: We retrospectively evaluated intrathoracic lymph nodes using FDG PET and CT data in 73 consecutive patients with recurrent or metastatic breast cancer who had both CT and FDG PET within 30 days of each other. In reviews of CT scans, mediastinal nodes measuring 1 cm or greater in the short axis were considered positive. PET was considered positive when there were one or more mediastinal foci of FDG uptake greater than the mediastinal blood pool.

RESULTS: Overall, 40% of patients had abnormal mediastinal or IM FDG uptake consistent with metastases, compared with 23% of patients who had suspiciously enlarged mediastinal or IM nodes by CT. Both FDG PET and CT were positive in 22%. In the subset of 33 patients with assessable follow-up by CT or biopsy, the sensitivity, specificity, and accuracy for nodal disease was 85% , 90%, and 88%, respectively, by FDG PET; 54% , 85%, and 73%, respectively, by prospective interpretation of CT; and 50%, 83%, and 70%, respectively, by blinded observer interpretation of CT. Among patients suspected of having only locoregional disease recurrence (n = 33), 10 had unsuspected mediastinal or IM disease by FDG PET.

CONCLUSION: FDG PET may uncover disease in these nodal regions not recognized by conventional staging methods. Future prospective studies using histopathology for confirmation are needed to validate the preliminary findings of this retrospective study.

PURPOSE: We sought to determine whether therapy with single-agent fludarabine compared with chlorambucil alone or the combination of both agents had an impact on the incidence and spectrum of infections among a series of previously untreated patients with B-cell chronic lymphocytic leukemia (CLL).

PATIENTS AND METHODS: Five hundred fifty-four previously untreated CLL patients with intermediate/high-risk Rai-stage disease were enrolled onto an intergroup protocol. Patients were randomized to therapy with chlorambucil, fludarabine, or fludarabine plus chlorambucil. Data pertaining to infection were available on 518 patients. Differences in infections among treatment arms were tested with the Kruskal-Wallis, Wilcoxon, and χ2 tests.

RESULTS: A total of 1,107 infections (241 major infections) occurred in 518 patients over the infection follow-up period (interval from study entry until either reinstitution of initial therapy, therapy with a second agent, or death). Patients treated with fludarabine plus chlorambucil had more infections than those receiving either single agent (P < .0001). Comparing the two single-agent arms, there were more infections on the fludarabine arm (P = .055) per month of follow-up. Fludarabine therapy was associated with more major infections and more herpesvirus infections compared with chlorambucil (P = .008 and P = .004, respectively). Rai stage and best response to therapy were not associated with infection. A low serum immunoglobulin G was associated with number of infections (P = .02). Age was associated with incidence of major infection in the combination arm (P = .004).

CONCLUSION: Combination therapy with fludarabine plus chlorambucil resulted in significantly more infections than treatment with either single agent. Patients receiving single-agent fludarabine had more major infections and herpesvirus infections compared with chlorambucil-treated patients.

PURPOSE: Children younger than 24 months with small (< 550 g), favorable histology (FH) Wilms tumors (WTs) were shown in a pilot study to have an excellent prognosis when treated with nephrectomy only.

PATIENTS AND METHODS: A study of nephrectomy only for the tratment of selected children with FH WT was undertaken. Stringent stopping rules were designed to insure closure of the study if the true 2-year relapse-free survival rate was 90% or lower.

RESULTS: Seventy-five previously untreated children younger than 24 months with stage I/FH WTs for which the surgical specimen weighed less than 550 g were treated with nephrectomy only. Three patients developed metachronous, contralateral WT 1.1, 1.4, and 2.3 years after nephrectomy, and eight patients relapsed 0.3 to 1.05 years after diagnosis (median, 0.4 years; mean, 0.51 years). The sites of relapse were lung (n = 5) and operative bed (n = 3). The 2-year disease-free (relapse and metachronous contralateral WT) survival rate was 86.5%. The 2-year survival rate is 100% with a median follow-up of 2.84 years. The 2-year disease-free survival rate (excluding metachronous contralateral WT) was 89.2%, and the 2-year cumulative risk of metachronous contralateral WT was 3.1%.

CONCLUSION: Children younger than 24 months treated with nephrectomy only for a stage I/FH WT that weighed less than 550 g had a risk of relapse, including the development of metachronous contralateral WT, of 13.5% 2 years after diagnosis. All patients who experienced relapse on this trial are alive at this time. This approach will be re-evaluated in a clinical trial using a less conservative stopping rule.

PURPOSE: The ability to prescribe treatment based on relative risks for normal tissue injury has important implications for oncologists. In non–small-cell lung cancer, increasing the dose of radiation may improve local control and survival. Changes in plasma transforming growth factor beta (TGFβ) levels during radiotherapy (RT) may identify patients at low risk for complications in whom higher doses of radiation could be safely delivered.

PATIENT AND METHODS: Patients with locally advanced or medically inoperable non–small-cell lung cancer received three-dimensional conformal RT to the primary tumor and radiographically involved nodes to a dose of 73.6 Gy (1.6 Gy twice daily). If the plasma TGFβ level was normal after 73.6 Gy, additional twice daily RT was delivered to successively higher total doses. The maximum-tolerated dose was defined as the highest radiation dose at which ≤ one grade 4 (life-threatening) late toxicity and ≤ two grade 3 to 4 (severe life-threatening) late toxicities occurred.

RESULTS: Thirty-eight patients were enrolled. Median follow-up was 16 months. Twenty-four patients were not eligible for radiation dose escalation beyond 73.6 Gy because of persistently abnormal TGFβ levels. Fourteen patients whose TGFβ levels were normal after 73.6 Gy were escalated to 80 Gy (n = 8) and 86.4 Gy (n = 6). In the 86.4-Gy group, dose-limiting toxicity was reached because there were two (33%) grade 3 late toxicities.

CONCLUSION: It is feasible to use plasma TGFβ levels to select patients for RT dose escalation for non–small-cell lung cancer. The maximum-tolerated dose using this approach is 86.4 Gy.

PURPOSE: To review and assign attribution for the causes of early deaths on two National Cancer Institute-sponsored cooperative group studies involving irinotecan and bolus fluorouracil (5-FU) and leucovorin (IFL).

PATIENTS AND METHODS: The inpatient, outpatient, and research records of patients treated on Cancer and Leukemia Group B protocol C89803 and on North Center Cancer Treatment Group protocol N9741 were reviewed by a panel of five medical oncologists not directly involved with either study. Each death was categorized as treatment-induced, treatment-exacerbated, or treatment-unrelated.

RESULTS: The records of 44 patients who experienced early deaths on C89803 (21 patients) or N9741 (23 patients) were reviewed. Patients treated with irinotecan plus bolus 5-FU/leucovorin had a three-fold higher rate of treatment-induced or treatment-exacerbated death than patients treated on the other arm(s) of the respective studies. For C89803, these rates were 2.5% (16 of 635) for IFL versus 0.8% (five of 628) for bolus weekly 5-FU and leucovorin. For N9741, these rates were 3.5% (10 of 289) for IFL, 1.1% (three of 277) for oxaliplatin plus bolus and infusional 5-FU and leucovorin, and 1.1% (three of 275) for oxaliplatin plus irinotecan. Multiple gastrointestinal toxicities that often occurred together were characterized into a gastrointestinal syndrome. Sudden, unexpected thromboembolic events were characterized as a vascular syndrome. The majority of deaths in both studies were attributable to one or both of these syndromes.

CONCLUSION: Close clinical monitoring, early recognition of toxicities and toxicity syndromes, aggressive therapeutic intervention, and withholding therapy in the presence of unresolved drug-related toxicities is recommended for patients receiving IFL or other intensive chemotherapy regimens.

PURPOSE: Kaposi’s sarcoma (KS) is the most common AIDS-related malignancy. Pulmonary involvement by KS (PKS) has carried a poor prognosis with median reported survival ranging from 3 to 10 months. We studied whether the introduction of highly active antiretroviral therapy (HAART; triple antiretroviral therapy including a protease inhibitor and two reverse transcriptase inhibitors) has been associated with improved survival for AIDS patients with PKS.

PATIENTS AND METHODS: A retrospective study was performed of 37 consecutive patients with PKS and human immunodeficiency virus infection in the tumor registry at a large municipal hospital in New York City between 1994 to 1997. There were 16 patients from 1994 to 1995 (pre-HAART period) and 21 patients from 1996 to 1997 (post-HAART period). The primary end point was survival, which was defined as time from start of chemotherapy until death from any cause.

RESULTS: Patients were analyzed by the date of diagnosis (pre- v post-HAART period) and whether or not they received HAART. Kaplan-Meier analysis showed significantly better survival in patients diagnosed in the post-HAART period (P = .0025). Additional Kaplan-Meier analysis indicated that patients on HAART had substantially better survival (P < .0001). Cox multivariate analyses showed that HAART therapy was associated with a reduced risk of death (hazard ratio = 0.09; 95% confidence interval, 0.03 to 0.69).

CONCLUSION: In patients with AIDS-associated PKS and undergoing chemotherapy, administration of HAART was associated with increased survival.
