Abstract
Doxorubicin is a commonly used chemotherapeutic agent to treat several malignancies, including aggressive tumors like triple-negative breast cancer. It has a limited therapeutic index owing to its extreme toxicity and the emergence of drug resistance. As a result, there is a pressing need to find innovative drugs that enhance the effectiveness of doxorubicin while minimizing its toxicity. The rationale of the present study is that combining emerging treatment agents or repurposed pharmaceuticals with doxorubicin might increase susceptibility to therapeutics and the subsequent establishment of improved pharmacological combinations for treating triple-negative breast cancer. Additionally, combined treatment will facilitate dosage reduction, reducing the toxicity associated with doxorubicin. Recently, the third-generation retinoid adapalene was reported as an effective anticancer agent in several malignancies. This study aimed to determine the anticancer activity of adapalene in TNBC cells and its effectiveness in combination with doxorubicin, and the mechanistic pathways in inhibiting tumorigenicity. Adapalene inhibits tumor cell growth and proliferation and acts synergistically with doxorubicin in inhibiting growth, colony formation, and migration of TNBC cells. Also, the combination of adapalene and doxorubicin enhanced the accumulation of reactive oxygen species triggering hyperphosphorylation of Erk1/2 and caspase-dependent apoptosis. Our results demonstrate that adapalene is a promising antitumor agent that may be used as a single agent or combined with present therapeutic regimens for TNBC treatment.

Evaluation of cardioprotective effects of carvedilol in dogs receiving doxorubicin chemotherapy: A prospective, randomized, double-blind, placebo controlled pilot study. Res Vet Sci 2021; 135:532-541. [PMID: 33221037 DOI: 10.1016/j.rvsc.2020.11.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 11/05/2020] [Accepted: 11/10/2020] [Indexed: 01/04/2023]
Abstract
The aim of this pilot study was to evaluate the cardioprotective effects of carvedilol in dogs receiving doxorubicin chemotherapy and provide suggestions to future studies based on results and limitations of our study. Thirteen dogs were randomized into two experimental groups: 6 dogs in carvedilol group and 7 dogs in placebo group. In carvedilol group, 0.39 mg/kg ± 0.04 twice-daily oral carvedilol was started on the day of the first doxorubicin treatment and continued throughout the chemotherapy protocol until the final cardiological evaluation. Cardiological evaluations were performed before the first doxorubicin administration and then 10 to 15 days after each subsequent dose. Troponin I and oxidative stress tests were performed with serum collected from dogs at the initial and final cardiological evaluation. Carvedilol produced some echocardiographic and electrocardiographic changes (reduced E velocity and E/IVRT ratio, as well reduced heart rate and increased PR and QT interval) due to its beta-block effect. In placebo group Doppler study showed a significant increase in mitral flow deceleration time (EDT), as well increased amplitude of the S wave in the right, and R wave in the left, precordial chest leads. There were significant difference in the EDT, E/IVRT and A' velocity, as well heart rate, PR interval and R wave in V4/CV6LU precordial chest lead between groups. In conclusion, some indexes of diastolic function and in precordial chest leads were less affected by doxorubicin in carvedilol than in control group. This suggests that carvedilol may have a beneficial effect in canine cancer patients receiving doxorubicin.

Effectiveness of doxorubicin-based and liposomal doxorubicin chemotherapies for patients with extra-abdominal desmoid-type fibromatosis: a systematic review. Jpn J Clin Oncol 2020; 50:1274-1281. [PMID: 32700733 DOI: 10.1093/jjco/hyaa125] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 06/22/2020] [Accepted: 06/25/2020] [Indexed: 12/27/2022] Open
Abstract
OBJECTIVE The treatment modality for desmoid-type fibromatosis has shifted from surgery to conservative treatment. The guideline committee for clinical care of extra-abdominal desmoid-type fibromatosis in Japan conducted a systematic review of treatment with doxorubicin-based chemotherapy for desmoid-type fibromatosis. METHODS We searched the pertinent literature. Two reviewers evaluated and screened it independently for eligibility and extracted data. They rated each report according to the grading of recommendations development and evaluation methodology. Based on the 'body of evidence', which the reviewers created, the clinical guideline committee decided a recommendation for the clinical question, 'Is doxorubicin-based chemotherapy effective for patients with extra-abdominal desmoid-type fibromatosis?' RESULTS Fifty-three articles were extracted by the literature search, and one from hand search. After the first and second screenings, five articles were subjected to the final evaluation. There were no randomized controlled trials. According to response evaluation criteria in solid tumors criteria, the response rates of doxorubicin-based regimens and liposomal doxorubicin were 44% (28.6-54) and 33.3% (0-75) on average, respectively. In two reports, the response rates of doxorubicin-based regimens were higher than those of non-doxorubicin-based ones; 54% vs 12%, 40% vs 11%, respectively. The rates of G3 or G4 complications according to common terminology criteria for adverse events were 28% and 13% with doxorubicin-based and liposomal doxorubicin chemotherapy, respectively, including neutropenia or cardiac dysfunction. None of the reports addressed the issue of QOL. CONCLUSION Although the evidence level was low in the evaluated studies, doxorubicin-based and liposomal doxorubicin chemotherapy was observed to be effective. However, doxorubicin-based chemotherapy is associated with non-ignorable adverse events, and is not covered by insurance in Japan. We weakly recommend doxorubicin-based chemotherapy for patients with extra-abdominal desmoid-type fibromatosis in cases resistant to other treatments.

Intramuscular Diphenhydramine Does Not Affect Acute Doxorubicin Infusion-Related Arrhythmia Number or Severity in a Prospective Crossover Study in Canine Lymphoma: A Pilot Study. Front Vet Sci 2020; 7:368. [PMID: 32766291 PMCID: PMC7379900 DOI: 10.3389/fvets.2020.00368] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Accepted: 05/27/2020] [Indexed: 11/13/2022] Open
Abstract
Background: Doxorubicin (DOX) is one of the most effective chemotherapeutics for canine high-grade lymphoma. In addition to dose-dependent chronic cardiotoxicity, DOX can trigger acute cardiac arrhythmias during drug infusion. Diphenhydramine premedication is commonly used, as histamine release is a proposed mechanism for DOX-associated arrhythmogenesis. Hypothesis/Objectives: The study objectives were to evaluate the incidence and severity of DOX infusion-related cardiac arrhythmias in dogs with high-grade lymphoma and evaluate the effect of diphenhydramine premedication on arrhythmia frequency and severity during and after DOX infusion. Animals: Twenty-two client-owned dogs with cytologically/histopathologically confirmed high-grade lymphoma were recruited, of which 19 were enrolled and 9 completed the study. Methods: Dogs were screened by echocardiogram and concurrent electrocardiogram for this randomized prospective crossover study. Group A received no premedication for DOX #1 and was premedicated with diphenhydramine for DOX #2; Group B received diphenhydramine with DOX #1 and no premedication for DOX #2. For both visits, Holter monitor data were collected for 1 h pre-DOX and 3 h post-DOX administration. Results: Nineteen dogs were enrolled and 9 dogs [Group A (5), Group B (4)] completed the protocol. There was no statistical difference between the DOX alone and DOX + diphenhydramine when evaluating the total number of ventricular premature complexes (VPCs, P = 0.34), change in VPCs/hour (P = 0.25), total number of atrial premature complexes (APCs, P = 0.5), change in APCs/hour (P = 0.06), or ventricular arrhythmia severity score (P > 0.99). Conclusions and clinical importance: This study demonstrates that in these dogs with rigorous pretreatment cardiovascular screening, DOX infusion did not induce significant arrhythmias. Furthermore, these data suggest that, with this screening approach, diphenhydramine may not alter the arrhythmia number or severity in canine DOX recipients.

Abstract
Background Soft-tissue sarcoma (sts) represents a rare group of mesenchymal neoplasms comprising more than 50 heterogeneous subtypes. Great efforts have been made to increase the understanding of the treatment of advanced sts (unresectable or metastatic disease). We set out to determine whether outcomes for patients with advanced sts have improved over time and to assess the current evidence for systemic therapy. Methods In a scoping review, we evaluated the contemporary evidence for systemic treatment of advanced sts in adults (>18 years of age). Phase i, ii, and iii studies of systemic therapy for advanced sts published in the English language were included. After abstract and full-text review of seventy-seven studies, sixty-two trials met the inclusion criteria. Results The number of clinical trials conducted and published in advanced sts has increased over the last 30 years. Although median overall survival has increased, attempts at improving first-line therapy through dose intensification, doublet chemotherapy, or alternative backbones have not been successful. The optimal therapy beyond anthracyclines remains a challenge, especially given the heterogeneity that grouping multiple sts subtypes within clinical trials creates. However, increasing numbers of agents are being studied, and several studies had shown isolated benefit in progression-free or overall survival. Summary First-line systemic therapy with an anthracycline remains the standard of care for advanced sts. However, choice of subsequent therapy beyond anthracyclines remains challenging. Novel systemic therapies, use of molecular diagnostics to direct therapy, subtype-specific trials, and learnings from real-world retrospective data are all important for improving outcomes in patients with advanced sts.

Abstract
Anthracyclines are integral components of antileukemic treatment. Apart from cardiotoxicity, myelosuppression and infectious complications have been described for doxorubicin (DOX) and daunorubicin (DNR) as predominant side effects, but little is known about their differential toxicities. To address the question whether DNR is associated with a lower rate of infectious complications compared with DOX, 307 children with newly diagnosed acute lymphoblastic leukemia, enrolled in trial CoALL 08-09, were randomized to receive either DOX 30 mg/m2 (n = 153) or DNR 36 mg/m2 (n = 154) in delayed intensification. Hematologic toxicities and stomatitis were less frequent in the DNR group resulting in a significantly lower rate of infections in the DNR arm (27% vs. 59%, p < .0001). Survival was equal in both arms (95% SE 2%) (p = .55), with an insignificant difference in the relapse rate (RR 0.12 (SE = 0.03) in the DOX arm vs. 0.16 (SE = 0.04) in the DNR arm; p = .37; Hazard ratio 1.3; 95% confidence interval 0.7-2.6). In conclusion, DNR given in delayed intensification is associated with a lower incidence of infectious complications without loss of efficacy.

Abstract
The paper reports the results of a prospective controlled study with two drug combinations (adriamycin plus bleomycin versus cyclophosphamide plus vincristine) in 34 consecutive patients with advanced or recurrent carcinoma of uterine cervix. Despite adequate dosage, the incidence of complete and partial remission was low (10% vs 20%) and not superior to that usually obtained with single agent chemotherapy. By adding objective improvement, the over all response rate was 47% and 26%, respectively. The duration of complete plus partial remission was 7.5 and 7.2 months, the median survival for responders 19 and 8.3 months, respectively. After cross over, adriamycin plus bleomycin yielded response in 4/10 patients, cyclophosphamide plus vincristine objective improvement in 1/3 patients. Since the control of advanced cervical carcinoma remains difficult, a combined modality approach with radiotherapy plus adjuvant chemotherapy for stages IIB and III appears worth of trial.

Abstract
This paper reviews the effects of adriamycin (ADM) observed in a series of 485 patients (419 adults and 66 children) treated at the Istituto Nazionale Tumori, Milan, from September 1968 to December 1973. Nine two patients were insufficiently treated to provide meaningful information on drug effects. The drug was administered by rapid intravenous injection through 6 dose schedules. In the last two schedules ADM was administered every 3 weeks at the dose of 20–25 mg/m2 for 3 consecutive days (schedule E) or of 60–75 mg/m2 in a single injection (schedule F). With schedules E and F there was an appreciable decrease in the incidence of stomatitis and of severe myelosuppression. Thrombocytopenia occurred in about 10 % of patients. The overall incidence of cardiomyopathy was 1.9 %. As observed by American investigators, cardiomyopathy occurred especially after a total dose exceeding 600 mg/m2 (17 %) and 4/9 patients died of irreversible heart failure. Congestive failure occurred in 7/9. In 6/9 patients showing cardiomyopathy ADM was administered through schedules E or F. One patient was a child 3 years old and 8 were adults with a mean age of 39 years. Non specific electrocardiographic abnormalities were present in about 10 % of patients during treatment with ADM but only exceptionally were they able to predict subsequent cardiomyopathy. The therapeutic results were promising in several types of previously treated and untreated neoplastic disease. The best responses (complete plus partial remission greater than 50 %) were observed in the group of malignant lymphomas (44%) especially in histiocytic lymphoma (67 %), in Ewing's sarcoma (41 %), Wilms's tumor (55 %), carcinoma of thyroid (45 %), testicular tumors (39 %), neuroblastoma (38 %), naso-pharyngeal carcinoma (29 %), breast cancer (26 %), as well as in the small series of acute and chronic myeloproliferative disorders. Significant regressions were also obtained in transitional carcinoma of urinary bladder (2/6) ovarian carcinomas (29 %), in soft tissue sarcomas (22 %) and in mesothelioma (25 %). A lower rate of substantial tumor response was seen in bronchogenic (15 %) and gastrointestinal carcinomas (22 %) as well as in epidermoid carcinomas of head and neck (10 %). No significant regression was noted in osteogenic sarcomas, chondrosarcoma, renal carcinoma and malignant melanoma. In responsive patients the mean duration of response was usually short. This could be in part explained by the fact that (41 %) of patients had previously been treated with conventional drugs. Our experience shows that ADM is useful in a number of neoplastic diseases, where it produces a prompt tumor regression in responsive patients. The successful results achieved with ADM as a single agent indicate that the drug should be incorporated in several protocols of combination chemotherapy and of combined treatment modalities provided the total dose does not exceed 550 mg/m2.

Abstract
An accidental extravasation of anthracycline-containing chemotherapy is a feared complication that may lead to necrosis and severe tissue destruction. For four decades, much effort has been done to prevent and treat this devastating condition. Savene™ has recently been proved to be very effective, and is the only approved treatment against anthracyline extravasation. It is thus now widely recommended. The present article represents a comprehensive review of, and historical insight to, the experimental and clinical studies of surgical and non-surgical treatments of extravasation during forty years of clinical anthracycline treatment.

Abstract
To ensure genomic integrity, living organisms have evolved diverse molecular processes for sensing and repairing damaged DNA. If improperly repaired, DNA damage can give rise to different types of mutations, an important class of which are genomic structural variants (SVs). In spite of their importance for phenotypic variation and genome evolution, potential contributors to SV formation in Saccharomyces cerevisiae (budding yeast), a highly tractable model organism, are not fully recognized. Here, we developed and applied a genome-wide assay to identify yeast gene knockout mutants associated with de novo deletion formation, in particular single-strand annealing (SSA)-mediated deletion formation, in a systematic manner. In addition to genes previously linked to genome instability, our approach implicates novel genes involved in chromatin remodeling and meiosis in affecting the rate of SSA-mediated deletion formation in the presence or absence of stress conditions induced by DNA-damaging agents. We closely examined two candidate genes, the chromatin remodeling gene IOC4 and the meiosis-related gene MSH4, which when knocked-out resulted in gene expression alterations affecting genes involved in cell division and chromosome organization, as well as DNA repair and recombination, respectively. Our high-throughput approach facilitates the systematic identification of processes linked to the formation of a major class of genetic variation.

Abstract
INTRODUCTION Globally, breast cancer is the most common life-threatening malignant disease among women. Adjuvant chemotherapeutic treatment of anthracycline-based chemotherapy (e.g., doxorubicin) has been shown to be more advantageous over non-anthracycline-based therapies, yet possess the tenacity of developing resistance and potential side effects which have limited its use in the clinical setting. These reasons necessitate combining doxorubicin with emerging photodynamic treatment regimens. Areas covered: In this review, the authors have concisely explained doxorubicin chemotherapy and the photobiological processes of phthalocyanine triggered photodynamic therapy (PDT). A literature search was conducted and reports demonstrating the use of doxorubicin and photodynamic therapy as a treatment modality for breast cancer were identified. More emphasis was made on studies demonstrating the efficacy and improved anticancer effect of combining chemotherapy with photodynamic therapy. However, it was concluded that for this combination therapy, still in it's infancy, it could be relevant when integrated into standard treatment. Expert Commentary: To these effects, comprehensive models based on experimental evaluations are needed for rational design of anthracycline-based chemotherapy and PDT to be integrated into the clinical setting.

Abstract
The process of karyotype evolution in Cervidae from a common ancestor (2n = 70, FN = 70) has been marked by complex chromosomal rearrangements. This ancestral karyotype has been retained by the current species Mazama gouazoubira (Fischer 1814), for which a chromosomal polymorphism (Robertsonian translocations and the presence of B chromosomes) has been described, presumably caused by a chromosome fragility. Thus, this study has identified doxorubicin-induced chromosome aberrations and mapped the regions involved in breaks, which may be related to the chromosome evolution process. G-banding pattern showed that 21 pairs of chromosomes presented chromosomal aberrations, 60% of the total chromosome number of the species M. gouazoubira. Among chromosomes that carry aberrations, the region where they were most frequently concentrated was distal relative to the centromere. These data suggest that certain chromosomal regions may be more susceptible to chromosome fragility and consequently could be involved in karyotype differentiation in species of the family Cervidae.

Abstract
Breast cancer is the most common cause of cancer and cancer death worldwide. Although most patients present with localized breast cancer and may be rendered disease-free with local therapy, distant recurrence is common and is the primary cause of death from the disease. Adjuvant systemic therapies are effective in reducing the risk of distant and local recurrence, including endocrine therapy, anti-HER2 therapy, and chemotherapy, even in patients at low risk of recurrence. The widespread use of adjuvant systemic therapy has contributed to reduced breast cancer mortality rates. Adjuvant cytotoxic chemotherapy regimens have evolved from single alkylating agents to polychemotherapy regimens incorporating anthracyclines and/or taxanes. This review summarizes key milestones in the evolution of adjuvant systemic therapy in general, and adjuvant chemotherapy in particular. Although adjuvant treatments are routinely guided by predictive factors for endocrine therapy (hormone receptor expression) and anti-HER2 therapy (HER2 overexpression), predicting benefit from chemotherapy has been more challenging. Randomized studies are now in progress utilizing multiparameter gene expression assays that may more accurately select patients most likely to benefit from adjuvant chemotherapy.

Abstract
Animal models are of great importance for medical research. They have enabled analysis of the aetiology and pathogenesis of complex congenital malformations and have also led to major advances in the surgical and therapeutic management of these conditions. Animal models allow us to comprehend the morphological and molecular basis of disease and consequently to discover novel approaches for both surgical and medical therapy. The anthracycline antibiotic adriamycin was incidentally found to have teratogenic effects on rats, producing a range of defects remarkably similar to the VACTERL association of congenital anomalies in humans, providing a reproducible animal model of this condition. VACTERL association is a spectrum of birth defects which includes vertebral, anal, cardiovascular, tracheo-oesophageal, renal and limb anomalies. In recent years, adriamycin rodent models of VACTERL have provided valuable insights into the pathogenesis of this complex association, particularly in relation to tracheo-oesophageal malformations. The adriamycin rat model and adriamycin mouse model are now well established in the investigation of the morphology of faulty organogenesis and the regulation of gene expression in tracheo-oesophageal anomalies.

Abstract
BACKGROUND The anthracyclines daunorubicin (DNR) and doxorubicin (DOX) are among the most important drugs in the treatment of childhood acute lymphoblastic leukemia, however there are conflicting in vitro data about the comparative efficacy and equivalent doses of both anthracyclines. To address the question of in vivo efficacy of both anthracyclines, patients enrolled in the CoALL 07-03 trial were randomized to receive one single dose of either doxorubicin 30 mg/m(2) , daunorubicin 30 mg/m(2) , or daunorubicin 40 mg/m(2) upfront induction therapy. PROCEDURE Children with newly diagnosed B-Precursor ALL or T-ALL were eligible for the randomized comparison. From the percentage of blasts and the white blood cell count (WBC) the absolute number of leukemic cells per µl peripheral blood (PB) was calculated and the initial value before DOX/DNR infusion equated as 100%. Main target criterion of this study was the leukemic cell decrease from Day 0 to Day 7. RESULTS Seven hundred forty three patients were randomized: 247 to the DOX; 252 to the DNR 30 mg/m(2) ; and DNR to the 40 mg/m(2) arm. The in vivo response was similar in all three treatment arms with a comparable blast decline in the peripheral blood. The percentages of patients with a clear non-response (M3 marrow) and moreover, the level of minimal residual disease (MRD) on Day 15 or at the end of induction were similar. CONCLUSION In vivo efficacy of a single dose daunorubicin 30 or 40 mg/m(2) is similar to that of doxorubicin given in a dose of 30 mg/m(2) .

Abstract
We searched for a drug capable of sensitization of sarcoma cells to doxorubicin (DOX). We report that the dual PI3K/mTOR inhibitor PI103 enhances the efficacy of DOX in several sarcoma cell lines and interacts with DOX in the induction of apoptosis. PI103 decreased the expression of MDR1 and MRP1, which resulted in DOX accumulation. However, the enhancement of DOX-induced apoptosis was unrelated to DOX accumulation. Neither did it involve inhibition of mTOR. Instead, the combination treatment of DOX plus PI103 activated Bax, the mitochondrial apoptosis pathway, and caspase 3. Caspase 3 activation was also observed in xenografts of sarcoma cells in nude mice upon combination of DOX with the specific PI3K inhibitor GDC-0941. Although the increase in apoptosis did not further impact on tumor growth when compared to the efficient growth inhibition by GDC-0941 alone, these findings suggest that inhibition of PI3K may improve DOX-induced proapoptotic effects in sarcoma. Taken together with similar recent studies of neuroblastoma- and glioblastoma-derived cells, PI3K inhibition seems to be a more general option to sensitize tumor cells to anthracyclines.

Abstract
PURPOSE MMT95 was the fourth of a series of International Society of Pediatric Oncology (SIOP) collaborations for children with high-risk nonmetastatic soft tissue sarcoma (STS). The principal objective was to explore survival advantage for an intensified chemotherapy strategy in a randomized trial. PATIENTS AND METHODS From July 1995 to June 2003, 457 previously untreated patients with incompletely resected embryonal rhabdomyosarcoma (RMS), undifferentiated sarcoma, and soft tissue primitive neuroectodermal tumor at all sites except paratesticular, vagina, and uterus, or with alveolar RMS were randomly assigned to receive either ifosfamide, vincristine, and dactinomycin (IVA) or a six-drug combination (IVA plus carboplatin, epirubicin, and etoposide) both delivered over 27 weeks. Cumulative doses were as follows: ifosfamide 54 g/m(2) (both arms), epirubicin 450 mg/m(2), etoposide 1,350 mg/m(2) (six-drug regimen). Poor responders after three courses of IVA were to be switched to the other arm. Delivery of radiotherapy was determined according to site and/or response to chemotherapy with or without surgery. RESULTS Overall survival (OS) for all patients was 81% (95% CI, 77% to 84%) at 3 years. No significant difference in outcome in either OS or event-free survival was noted between the two arms (3-year OS: 82% [95% CI, 76% to 86%] for IVA and 80% [95% CI, 74% to 85%] for the six-drug arm). Toxicity was significantly greater (infection, myelosuppression, and mucositis) in the six-drug arm. Overall burden of local therapy was consistent with data from previous SIOP studies and showed no difference between the two chemotherapy regimens. CONCLUSION Intensification of chemotherapy for nonmetastatic RMS and other chemotherapy-sensitive STS provides no survival advantage or reduction in the intensity of local therapy and adds toxicity.

Abstract
Ewing sarcoma, a rare malignancy of childhood and adolescence, has become a model of advances in diagnosis, treatment, and outcome through long-standing research efforts in multinational clinical trials. With modern multimodal regimens consisting of local surgery and/or radiotherapy plus intensive systemic chemotherapy, survival can be achieved for ≈ 70% of patients with localized disease. However, in the last decade, improvement in survival curves has slowed down. Also, a relapse rate of ≈ 30% remains unacceptable, since salvage strategies for Ewing sarcoma recurrence are discouraging and prognosis is unfavorable in most cases. Metastatic disease at diagnosis poses a similar challenge, since even if remission is achieved, relapse frequently occurs despite the most intensive treatment. Urgently needed, novel biology-driven treatment options are now beginning to emerge on the horizon, but have not yet reached the standard of care. An overview of the current clinical state-of-the-art is provided in this article.

Abstract
The role of doxorubicin in treatment of rhabdomyosarcoma (RMS) has been controversial for 30 years. Despite its known activity in RMS, because of its risk of cardiotoxicity, its use is not justified in low-risk patients who have an excellent chance of cure with vincristine, actinomycin with or without cyclophosphamide, and primary tumor treatment. For patients with intermediate and high risks, the risk/benefit ratio must be carefully considered. In addition, the peak incidence of RMS is in toddlers, with whom the risk of cardiotoxicity of anthracyclines is higher. A number of trials both in North America and Europe, which are reviewed in this article, have investigated the role of doxorubicin in RMS, with no conclusive outcomes. In addition, differences in risk-group assignment on two sides of the Atlantic further complicate comparisons and analyses. The current European EpSSG 2005 study for high-risk RMS (by the European definition) may come closest to giving an answer to the role of doxorubicin in RMS.

Abstract
AIM Since the introduction of chemotherapy, survival in localised high-grade osteosarcoma has improved considerably. However, there is still no worldwide consensus on a standard chemotherapy approach. In this systematic review evidence for effectiveness of each single drug and the role of response guided salvage treatment of adjuvant chemotherapy are addressed, whereas in a meta-analysis the number of drugs in current protocols is considered. METHODS A systematic literature search for clinical studies in localised high-grade osteosarcoma was undertaken, including both randomised and non-randomised trials. Historical clinical studies from the pre-chemotherapy era were included for comparison purposes. RESULTS Nine historical studies showed a long-term survival of 16% after only local treatment. Fifty single agent phase II studies showed high response rates for adriamycin (A, 43%), ifosfamide (Ifo, 33%), methotrexate (M, 32%), cisplatin (P, 26%) but only 4% for etposide (E). In 19 neo-adjuvant studies the mean 5-year event free survival (EFS) was 48% for 2-drug regimens and 58% for ⩾3 drug regimens, with a 5-year overall survival (OAS) of 62% and 70%, respectively. Meta-analysis showed that ⩾3 drug regimens including methotrexate plus adriamycin plus cisplatin (plus ifosfamide) (MAP(Ifo)) had significant better outcome (EFS: HR=0.701 (95% confidence interval [95% CI]: 0.615-0.799); OAS: HR=0.792 (95% CI: 0.677-0.926) than 2-drug regimens, but there was no significant difference between MAP and MAPIfo (or plus etoposide). Salvage of poor responders by changing drugs, or intensifying treatment postoperatively has not proven to be useful in this analysis. CONCLUSION Meta-analysis in patients with localised high-grade osteosarcoma shows that 3-drug regimens, for example MAP are the most efficacious drug regimens.

Abstract
Cardiotoxicity remains the limiting factor for many forms of cancer therapy and is the focus of growing research and clinical emphasis. This article outlines the current clinical evidence for left ventricular dysfunction and heart failure for the two most important classes of cardiotoxic chemotherapeutic agents, examines the potential pitfalls that have led to underestimated rates of left ventricular dysfunction from these agents, and reviews strategies for screening for and providing prophylaxis against chemotherapy-associated left ventricular dysfunction.

Abstract
Rhabdomyosarcoma is a typical tumor of childhood, characterized by a high grade of malignancy, local invasiveness and a marked propensity to metastasize, but also a generally good response to chemotherapy and radiotherapy. Multimodal therapy is essential to cure rhabdomyosarcoma patients, but different uses of surgery, radiotherapy and chemotherapy, and their intensity, need to be selected and modulated to different patient risk groups. This article attempts to give an account of the current treatment options, the open and debated issues and the potential novel strategies for the near future.

[PMID: 20416367 DOI: 10.1016/j.ijpharm.2010.04.018] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2009] [Revised: 04/14/2010] [Accepted: 04/15/2010] [Indexed: 02/05/2023]
Abstract
In our previous study, we developed a novel cationic liposome, which was modified with truncated human basic fibroblast growth factor (tbFGF) peptide. This tbFGF-mediated cationic liposome could deliver chemotherapeutic agents or gene specifically to FGFRs on tumors and obtained higher transfection efficiency than plain cationic liposomes. In order to investigate whether this novel cationic liposome could achieve a synergistic/combined anti-tumor effect as a co-delivery system, we simultaneously delivered doxorubicin (DOX) and the plasmid encoding the phosphorylation-defective mouse survivin threonine 34-->alanine mutant (Msurvivin T34A plasmid) to the same cells through this cationic liposome. As a result, an enhanced antiproliferative activity in vitro has been achieved by delivering DOX and DNA simultaneously to the Lewis lung carcinoma cells (LLC) using this liposome. The concentration of DOX in the co-delivery system which caused 50% killing was nearly 3-fold lower than that of the free DOX. Furthermore, the co-delivery system suppressed tumor growth more efficiently than either DOX or the Msurvivin T34A plasmid alone in the Lewis lung carcinoma-bearing C57BL/6 mice. After 18 days of treatment with the co-delivery system, the average tumor volume in mice was decreased by 80%, which was higher than liposomal DOX (70%, P<0.05) and Msurvivin T34A plasmid (41%, P<0.01). The co-delivery system also caused 15 days delay of tumor growth, which was longer than the other treatment groups. In conclusion, this novel cationic liposome is an efficient vector to simultaneously deliver drugs and DNA to the same cells in vitro and in vivo.

Abstract
Nuclear factor of activated T cells (NFAT), a family of transcription factors, has been implicated in many cellular processes, including some cancers. Here, we characterize, for the first time, the role of NFAT3 in doxorubicin (DOX)-mediated apoptosis, migration, and invasion in SNB19 and U87 glioma cells. This study demonstrates that the specific knockdown of NFAT3 results in a dramatic inhibition of the apoptotic effect induced by DOX and favors cell survival. Inhibition of NFAT3 activation by shNFAT3 (shNF3) significantly downregulated tumor necrosis factor (TNF)-alpha induction, its receptor TNFR1, caspase 10, caspase 3, and poly (ADP-ribose) polymerase, abrogating DOX-mediated apoptosis in glioma cells. DOX treatment resulted in NFAT3 translocation to the nucleus. Similarly, shNF3 treatment in SNB19 and U87 cells reversed DOX-induced inhibition of cell migration and invasion, as determined by wound healing and matrigel invasion assays. Taken together, these results indicate that NFAT3 is a prerequisite for the induction of DOX-mediated apoptosis in glioma cells.

Abstract
BACKGROUND AND PURPOSE Doxorubicin evokes oxidative stress and precipitates cell apoptosis in testicular tissues. The aim of this study was to investigate whether the Ginkgo biloba extract 761 (EGb), a widely used herbal medicine with potent anti-oxidant and anti-apoptotic properties, could protect testes from such doxorubicin injury. EXPERIMENTAL APPROACH Sprague-Dawley male rats (8 weeks old) were given vehicle, doxorubicin alone (3 mg kg(-1) every 2 days for three doses), EGb alone (5 mg kg(-1) every 2 days for three doses), or EGb followed by doxorubicin (each dose administered 1 day after EGb). At 7 days after the first drug treatment oxidative and apoptotic testicular toxicity was evaluated by biochemical, histological and flow cytometric analyses. KEY RESULTS Compared with controls, testes from doxorubicin-treated rats displayed impaired spermatogenesis, depleted haploid germ cell subpopulations, increased lipid peroxidation products (malondialdehyde), depressed antioxidant enzyme activities (superoxide dismutase, glutathione peroxidase and glutathione), reduced antioxidant enzyme expression (superoxide dismutase) and elevated apoptotic indexes (pro-apoptotic modulation of Bcl-2 family proteins, intensification of p53 and Apaf-1, release of mitochondrial cytochrome c, activation of caspase-3 and increase of terminal deoxynucleotidyl transferase nick-end labelling/sub-haploid cells), while EGb pretreatment effectively alleviated all of these doxorubicin-induced abnormalities in testes. CONCLUSIONS AND IMPLICATIONS These results demonstrate that EGb protected against the oxidative and apoptotic actions of doxorubicin on testes. EGb may be a promising adjuvant therapy medicine, potentially ameliorating testicular toxicity of this anti-neoplastic agent in clinical practice.

Abstract
AIMS The objective of this study was to investigate whether a cytoprotective herb-derived agent, Ginkgo biloba extract (EGb) 761, could have a beneficial effect on doxorubicin-induced cardiac toxicity in vitro and in vivo. METHODS AND RESULTS Primary cultured neonatal rat cardiomyocytes were treated with the vehicle, doxorubicin (1 microM), EGb761 (25 microg/mL), or EGb761 plus doxorubicin. After 24 h, doxorubicin upregulated p53 mRNA expression, disturbed Bcl-2 family protein balance, disrupted mitochondrial membrane potential, precipitated mitochondrion-dependent apoptotic signalling, induced apoptotic cell death, and reduced viability of cardiomyocytes, whereas EGb761 pretreatment suppressed all the actions of doxorubicin. Similarly, rats treated with doxorubicin [3 mg/kg intraperitoneally (i.p.) three doses every other day] displayed retarded growth of body and heart as well as elevated apoptotic indexes in heart tissue at both 7 and 28 days after exposure, whereas EGb761 pretreatment (5 mg/kg i.p. 1 day before each dose of doxorubicin) effectively neutralized the aforementioned gross and cellular adverse effects of doxorubicin. CONCLUSION Doxorubicin impairs viability of cardiomyocytes at least partially by activating the p53-mediated, mitochondrion-dependent apoptotic signalling. EGb761 can effectively and extensively counteract this action of doxorubicin, and may potentially protect the heart from the severe toxicity of doxorubicin.

Abstract
PURPOSE Many cooperative groups have reported on the chemo-sensitivity of rhabdomyosarcoma (RMS). Doxorubicin has been tested but remains a controversial treatment option. We report here the results of the up-front evaluation of the efficacy of doxorubicin in children and adolescents with high-risk metastatic RMS. PATIENTS AND METHODS Patients younger than 18 years of age (>6 months) with newly diagnosed, histologically confirmed high-risk metastatic RMS were required to have measurable disease, to have undergone no prior chemotherapy or radiation therapy and to have normal liver, renal and cardiac function before treatment. Doxorubicin was administered intravenously over 48h to a total dose of 60mg/m2. Two courses were given separated by a 21day interval. Response to therapy was assessed by diagnostic imaging after the second course. The study was designed as a two-stage procedure according to the multistep plan described by Fleming. RESULTS Twenty patients were eligible for analysis. Median age at diagnosis was 9.8 years (range from 2 to 16). Thirteen of the 20 patients treated in the first step responded to treatment, corresponding to an overall response to doxorubicin of 65% [95% confidence interval (CI), 44-85%]. The rates of CR and PR were 5% [95% CI, 0-14%] and 60% [95% CI, 39-81%], respectively. Four (20%) patients had progressive disease, corresponding to a progression rate of 20% [95% CI, 2-38%]. CONCLUSION This window study provides the definitive demonstration of the efficacy of doxorubicin in untreated RMS. Given the inconclusive results obtained from previous studies using differing schedules chemotherapy incorporating doxorubicin, the next step should be a randomised study testing dose intensity in high-risk localised RMS. This issue is being addressed in a current European study (EpSSG RMS 2005).

Abstract
BACKGROUND Over 50% of patients with rhabdomyosarcoma (RMS) have intermediate risk disease, with a 3-year failure-free survival (FFS) of 50%-70% depending on histology. Doxorubicin is active against RMS, but its role in improving outcome remains controversial. Ifosfamide is as active as cyclophosphamide in RMS, with the Fourth Intergroup RMS Study (IRS-IV) showing equivalent outcomes for patients treated with ifosfamide for the first 28 weeks compared to cyclophosphamide. Treatment with alternating cycles of non-cross-resistant chemotherapy has been used in a number of diseases with good results. PROCEDURE The results of a pilot study utilizing alternating courses of vincristine, doxorubicin, cyclophosphamide, and etoposide/ifosfamide (VDC/IE) were compared for outcome and patient characteristics to a group of similar matched patients treated on IRS-IV. RESULTS The 5-year FFS for patients with parameningeal (PM) primaries on IRS-IV and the VDC/IE study were 72% and 82%, respectively (P = 0.26); for patients with non-PM primaries, the estimated risk of failure for VDC/IE study versus IRS-IV was 0.54. Combining all disease sites and performing analysis for relative risk of failure for 46 VDC/IE patients and 342 IRS-IV patients, the relative risk of failure for the VDC/IE study compared to the IRS-IV study is 0.5 (P = 0.06). CONCLUSIONS VDC/IE is as effective therapy for intermediate risk RMS as IRS-IV therapy. It is being explored along with irinotecan in relapsed patients and newly diagnosed high-risk patients.

Abstract
Spermatogenic cells constitute one of the body tissues that are susceptible to doxorubicin-induced oxidative stress and apoptosis. To explore whether doxorubicin toxicity to these male germ cells could be prevented by adjuvant medication, this study was designed to examine the possible ameliorating action of doxycycline, an antibiotic with anti-oxidant property, on doxorubicin-induced oxidative and apoptotic effects in mouse testes. Male mice at 5-week of age were treated with vehicles, doxorubicin alone (3 mg/kg, i.p. every other day for 3 doses), doxycycline alone (2.5 mg/kg, i.p. every other day for 3 doses), or doxycycline plus doxorubicin (each dose given 1 day post-doxycycline). After 28 days, mice treated with doxorubicin alone displayed smaller body and testicular weights, reduced sperm counts, impaired spermatogenic capability (scarcer spermatids and spermatocytes), increased oxidative stress (malondialdehyde levels), decreased anti-oxidant activity (superoxide dismutase and glutathione peroxidase), and elevated apoptotic indexes (upregulation of Bax and Bad, downregulation of Bcl-2 and Bcl-xL, release of cytochrome c from mitochondria to cytosol, activation of caspase-3, and increase of cleaved caspase-3 abundance and TUNEL positive cells), while doxycycline pretreatment could effectively prevent nearly all of these abnormalities. These results provide firm evidence that doxycycline pretreatment would offset the oxidative and apoptotic impact imposed by doxorubicin, and imply doxycycline to be a promising adjuvant agent that may attenuate the toxicity of doxorubicin on testicular tissues in clinical practice.

Abstract
We previously showed that C-phycocyanin (PC), an antioxidant biliprotein pigment of Spirulina platensis (a blue-green alga), effectively inhibited doxorubicin-induced oxidative stress and apoptosis in cardiomyocytes. Here we investigated the cardioprotective effect of PC against ischemia-reperfusion (I/R)-induced myocardial injury in an isolated perfused Langendorff heart model. Rat hearts were subjected to 30 min of global ischemia at 37°C followed by 45 min of reperfusion. Hearts were perfused with PC (10 μM) or Spirulina preparation (SP, 50 mg/l) for 15 min before the onset of ischemia and throughout reperfusion. After 45 min of reperfusion, untreated (control) hearts showed a significant decrease in recovery of coronary flow (44%), left ventricular developed pressure (21%), and rate-pressure product (24%), an increase in release of lactate dehydrogenase and creatine kinase in coronary effluent, significant myocardial infarction (44% of risk area), and TdT-mediated dUTP nick end label-positive apoptotic cells compared with the preischemic state. PC or SP significantly enhanced recovery of heart function and decreased infarct size, attenuated lactate dehydrogenase and creatine kinase release, and suppressed I/R-induced free radical generation. PC reversed I/R-induced activation of p38 MAPK, Bax, and caspase-3, suppression of Bcl-2, and increase in TdT-mediated dUTP nick end label-positive apoptotic cells. However, I/R also induced activation of ERK1/2, which was enhanced by PC treatment. Overall, these results for the first time showed that PC attenuated I/R-induced cardiac dysfunction through its antioxidant and antiapoptotic actions and modulation of p38 MAPK and ERK1/2.

Abstract
The effect of CardiPro, a polyherbal formulation, with an antioxidant property, has been studied on doxorubicin (DXR)-induced cardiotoxicity in mice. CardiPro (150 mg/kg b.w., twice daily was administered orally for 7 weeks along with four equal injections (each containing 4.0 mg/kg b.w., DXR) intraperitoneally, once weekly (cumulative dose 16 mg/kg). After a 3-week post DXR treatment period, cardiotoxicity was assessed by noting mortality, volume of ascites, liver congestion, changes in heart weight, myocardial lipid peroxidation, antioxidant enzymes and histology of heart. DXR-treated animals showed higher mortality (50%) and more ascites. Myocardial SOD and glutathione peroxidase activity were decreased and lipid peroxidation was increased. Histology of heart of DXR-treated animals showed loss of myofibrils and focal cytoplasmic vacuolization. CardiPro significantly protected the mice from DXR-induced cardiotoxic effects as evidenced by lower mortality (25%), less ascites, myocardial lipid peroxidation, normalization of antioxidant enzymes and minimal damage to the heart histologically. Our data confirm the earlier reports that DXR cardiotoxicity is associated with the free radical-induced tissue damage. Administration of CardiPro, with an antioxidant property, protected the DXR-induced cardiotoxicity in mice.

Abstract
Doxorubicin (DOX), a widely used antitumour drug, causes dose-dependent cardiotoxicity. Cardiac mitochondria represent a critical target organelle of toxicity during DOX chemotherapy. Proposed mechanisms include generation of ROS (reactive oxygen species) and disturbances in mitochondrial calcium homoeostasis. In the present study, we probed the mechanistic link between mitochondrial ROS and calcium in the embryonic rat heart-derived H9c2 cell line and in adult rat cardiomyocytes. The results show that DOX stimulates calcium/calcineurin-dependent activation of the transcription factor NFAT (nuclear factor of activated T-lymphocytes). Pre-treatment of cells with an intracellular calcium chelator abrogated DOX-induced nuclear NFAT translocation, Fas L (Fas ligand) expression and caspase activation, as did pre-treatment of cells with a mitochondria-targeted antioxidant, Mito-Q (a mitochondria-targeted antioxidant consisting of a mixture of mitoquinol and mitoquinone), or with adenoviral-over-expressed antioxidant enzymes. Treatment with GPx-1 (glutathione peroxidase 1), MnSOD (manganese superoxide dismutase) or a peptide inhibitor of NFAT also inhibited DOX-induced nuclear NFAT translocation. Pre-treatment of cells with a Fas L neutralizing antibody abrogated DOX-induced caspase-8- and -3-like activities during the initial stages of apoptosis. We conclude that mitochondria-derived ROS and calcium play a key role in stimulating DOX-induced 'intrinsic and extrinsic forms' of apoptosis in cardiac cells with Fas L expression via the NFAT signalling mechanism. Implications of ROS- and calcium-dependent NFAT signalling in DOX-induced apoptosis are discussed.

Abstract
BACKGROUND The objective of this report was to estimate long-term outcome and prognostic factors in children and adolescents who presented with metastatic osteosarcoma at diagnosis. Patients were treated in six French pediatric oncology centers with surgery and multiagent chemotherapy, mainly with high-dose methotrexate. Their medical records were reviewed retrospectively. METHODS The medical records of patients who were treated for metastatic osteosarcoma from 1987 to 2000 were reviewed. Patients were treated with the chemotherapy regimens recommended for nonmetastatic disease in children (the French Society of Pediatric Oncology OS 87 and OS 94 protocols) or, in a few patients, with other chemotherapy regimens. Surgical excision of the primary tumor and, when possible, of all metastatic sites was performed based on a personalized assessment of each patient's situation. RESULTS Seventy-eight patients age < 20 years were treated. Forty-six patients (59%) had only 1 metastatic site (35 to the lungs and 11 to bone). Twenty-eight patients (36%) achieved a complete remission after combination chemotherapy and surgery. The event-free survival and overall survival rates at 5 years were 14% and 19%, respectively. To date, 14 patients (18%) have remained alive with a median follow-up of 112 months. Pretreatment features associated with a shorter event-free survival in the multivariate analysis were metastasis to at least two organs and high alkaline phosphatase level. Patients with at least 1 of these poor prognostic factors had a 2.6% event-free survival rate at 5 years despite treatment. CONCLUSIONS The survival of patients with metastatic osteosarcoma were treated with conventional chemotherapy and surgery remained very poor. Patients should be classified into different prognostic groups and treated accordingly. New therapeutic approaches are warranted to improve the prognosis for patients with the most severe disease.

Abstract
The generation of reactive oxygen species and mitochondrial dysfunction has been implicated in doxorubicin (DOX)-induced cardiotoxicity. The aim of the present study was to determine whether Spirulina, a blue-green algae, could serve as a cardioprotective agent during DOX treatment in a mouse model. Mice were treated with DOX (4 mg/kg bw, intraperitoneally), weekly, for 4 weeks. Spirulina was administered orally for 3 days twice daily, then for 7 weeks along with the four equal injections of DOX. Cardiotoxicity was assessed, at 3 weeks after the end of the DOX-treatment period, by mortality, volume of ascites, liver congestion, oxidative stress and ultrastructural changes of heart tissue. The DOX-treated animals showed higher mortality (53%) and more ascites. Myocardial damage, as assessed by ultrastructural changes, showed loss of myofibrils, cytoplasmic vacuolization and mitochondrial swelling. Myocardial superoxide dismutase and glutathione peroxidase activities were decreased and lipid peroxidation was increased. Pretreatment with Spirulina significantly protected the mice from DOX-induced cardiotoxic effects as evidenced from lower mortality (26%), less ascites, lower levels of lipid peroxidation, normalization of antioxidant enzymes and ultrastructural studies showing minimal damage to the heart. In vitro cytotoxic studies using ovarian cancer cells demonstrated that Spirulina did not compromise the anti-tumor activity of doxorubicin. These results suggest that Spirulina has a protective effect against cardiotoxicity induced by DOX and it may, therefore, improve the therapeutic index of DOX.

Abstract
Multidrug resistance (MDR) is a major obstacle to successful clinical cancer chemotherapy. A novel doxorubicin anti-resistant Stealth liposomes (DARSLs), prepared by co-encapsulating doxorubicin (DOX) and verapamil (VER) into stealth liposomes, has been developed. The average particle size of DARSLs was 118.1+/-22.3 nm. Encapsulation efficiencies of DOX and VER in DARSLs were greater than 95% and 70%, respectively. The IC(50) of DARSLs as measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide (MTT) assay in multidrug resistant rat prostate cancer Mat-LyLu-B2 (MLLB2) cells was 0.079+/-0.017 microM, 13 fold less than that for liposomal DOX with free VER (LDFV 0.96+/-0.46 microM) but only about 2 times less than FDFV. The IC(50) cytotoxicity on MLLB2 cells of the various formulations was as follows: DARSLs approximately LDLV<FDFV<FDLV<LDFV<LD<FD, (LD: liposomal DOX; LV: liposomal VER; FD: free DOX; FV: free VER). Similar cytotoxicities were shown between DARSLs and FDFV in DOX-resistant human uterus sarcoma MES-SA/DX5 cells, reversing DOX-resistance to that shown by FD on DOX-sensitive MES-SA cells. For MLLB2 cells, DARSLs was the most cytotoxic, but its intracellular concentration of DOX, measured as mean cellular fluorescence with flow cytometry was lower (p<0.01) than that observed with the FDFV formulation. In conclusion, DARSLs was an effective DOX formulation which could overcome drug resistance in DOX-resistant tumor cells, but its mechanisms of action may be complex.

Abstract
PURPOSE To evaluate local control, event-free survival, and overall survival for patients with parameningeal (PM) rhabdomyosarcoma (RMS) treated with intensive chemotherapy and delayed irradiation. PATIENTS AND METHODS Thirteen consecutive patients with PM RMS were treated with an institutional protocol from 1992 to 1998 at the University of Washington/Children's Hospital and Regional Medical Center and Deaconess Medical Center. Patients received intensive chemotherapy consisting of vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide prior to radiotherapy. Irradiation was delayed, in contrast to current Intergroup Rhabdomyosarcoma Study Group (IRSG) recommendations. RESULTS Median follow-up was 39 months. Eleven patients had high-risk features, including five with intracranial extension. All patients responded to the intensive chemotherapy, with 38% exhibiting a complete response and the remaining 62% a partial response. Radiation was administered a median of 21 weeks from initiation of chemotherapy. The Kaplan-Meier estimate of 5-year local control was 92%, with event-free survival and overall survival rates of 83%. CONCLUSIONS With intensive induction chemotherapy, delayed irradiation for PM RMS does not compromise local control. Event-free survival and overall survival rates compare favorably with recently IRSG trials employing early irradiation. Delaying irradiation allows for intensification of chemotherapy and could permit response-based radiation volume and/or dose modifications, which could decrease treatment-related morbidity.

Abstract
Neuroblastic tumors are a broad biological and clinical spectrum of neoplastic disease that has long captured the attention of clinicians and scientists alike. It is the most common solid extracranial tumor in children and accounts for 8-10% of all childhood tumors. Tumors are derived from neural crest cells and neural differentiation is common. Neuroblastoma is unique in that it presents with at least three distinct patterns of disease. Locoregional disease (Stage 1, 2, 3) does not metastasize to bone or bone marrow. Stage 4 is a systemic disease with widespread metastasis that responds to chemotherapy but many develop resistance. Stage 4s presents in infancy, is widespread and can spontaneously regress with no intervention, leaving a focus of fibrosis or calcification. Prognosis correlates with age, stage and tumor biological profile. The goal of this review is to provide an overview of the disease and highlight diagnostic, prognostic and therapeutic advances in neuroblastoma. Recommendations and resources for the evaluation and treatment of this disease are outlined.

Abstract
OBJECTIVE To conduct a retrospective evaluation of tetrahydropyranyladriamycin (PIR)-based combination chemotherapy for osteosarcomas in comparison with doxorubicin (DOX)-based regimens to determine differences in response and toxicities between DOX- and PIR-containing regimens. METHODS Toxicities and response rates of the 2 anthracyclines given as combination chemotherapy were assessed in patients with osteosarcoma, with 19 patients receiving PIR-based and 11 receiving DOX-based regimens. RESULTS The survival of osteosarcoma patients treated with PIR was significantly better than that with DOX (p = 0.023) based on 2-year follow-up. Adverse effects such as mucositis and diarrhea were also less pronounced in the PIR cohort. CONCLUSIONS PIR-based combination chemotherapy might be a useful and safe chemotherapeutic strategy for osteosarcomas compared with DOX regimens. Further assessment is necessary to confirm the safety and efficacy of this treatment.
