Vesicle size and composition are a critical parameter for determining the circulation half-life of liposomes. Size influences the degree of drug encapsulation in liposomes. The geometry, size, and properties of liposomes in an aqueous environment have to be described to enable potential applications of liposome systems as drug carriers. The characteristics of multiple thermotropic phase transitions are also an important consideration in liposomes used for analytical and bioanalytical purposes. The aim of this study was to evaluate the physicochemical properties of liposomes which accommodate hydrophilic and amphiphilic drugs used in cancer therapy. The studied liposomes were prepared with the involvement of the modified reverse-phase evaporation method (mREV). The prepared liposomes had a diameter of 70-150 nm. The analyzed compounds were 1-β- d-arabinofuranosylcytosine, cyclophosphamide, and ifosfamide. In literature, there is no information about simultaneous incorporation of cytarabine, ifosfamide, and cyclophosphamide, in spite of the fact that these drugs have been used for more than 30 years. A combination of the examined drugs is used in CODOX-M/IVAC therapy. CODOX-M/IVAC (cyclophosphamide, doxorubicin, high-dose methotrexate/ifosfamide, etoposide, and high-dose cytarabine) is one of the currently preferred intensive-dose chemotherapy regimens for Burkitt lymphoma (BL). The present research demonstrates the pioneering studies of incorporation of ifosfamide into liposome vesicles, location of and competition between the analyzed drugs and liposome vesicles. The applied methods were nuclear magnetic resonance (NMR), atomic force microscopy (AFM), differential scanning calorimetry (DSC).

Patients with intracranial germ cell tumor (IGCT) often present with pituitary dysfunction, including diabetes insipidus (DI). Recent protocols have used pre-radiation chemotherapy with combinations of etoposide, carboplatin and/or cisplatin, and ifosfamide. Management of DI in these patients requires monitoring of electrolytes and fluids during chemotherapy and hyperhydration. All consecutive patients treated with chemotherapy for an IGCT during the period 1990-2007 at the Hospital for Sick Children, Toronto were reviewed. Out of 32 patients who received chemotherapy, 21 had DI. Only cycles containing cisplatin and/or ifosfamide and hyperhydration were considered. DI and non-DI patients were compared for each cycle of chemotherapy. Patients were studied for number of days in hospital per chemotherapy course, daily fluid input and output, changes in dose, schedule and route of administration of desmopressin (DDAVP) during chemotherapy, daily variations in sodium level, electrolyte monitoring requirements per day, and complications related to fluid and electrolyte disturbances. Fifty-four cycles of chemotherapy in DI patients were compared to 25 cycles in non DI patients. All 21 patients with DI required daily change in dosage and schedule of DDAVP. Marked variations in daily sodium level were observed in the DI group. Seventeen courses required prolonged admission in the DI group (one in non DI patients) and 6 patients experienced serious complications. In conclusion, DI is a risk factor for complications when cisplatin and/or ifosfamide based protocols are used. The role of these agents in the management of ICGT should be carefully evaluated and guidelines for management of DI established.

The Southwest Oncology Group did a limited institutional pilot study of the combination of doxorubicin and ifosfamide in the treatment of previously treated adult patients with acute leukemia. Thirty-four patients received one or two courses of the combination. All patients had received prior chemotherapy and 32 had received prior anthracycline chemotherapy. Three patients died before their responses could be fully evaluated. Fourteen patients achieved complete remission (41%) and one patient achieved partial remission. The complete remission rate was 27% for patients with acute myeloblastic leukemia (myelomonoblastic leukemia, monoblastic leukemia, and erythroleukemia) and 89% for patients with acute lymphocytic and undifferentiated leukemia (ALL). Toxic effects included severe hematologic reactions in 33 of 34 patients, hematuria in six patients, altered sensorium in one patient, and congestive heart failure in one patient. The safety of the combination was established and toxic side effects of this therapy were tolerable. The 89% complete remission rate for previously treated patients with ALL suggests that the combination of doxorubicin and ifosfamide may be particularly effective in ALL.

Neutrophil gelatinase associated lipocalin (NGAL) have been used with great success in acute renal failure and in some cases in chronic nephrotoxicity. In this work, we aimed to investigate urinary NGAL as an early marker of chronic renal failure (CRF). We investigated urinary NGAL of 29 children treated with ifosfamide chemotherapy and compared them with those of 12 healthy children. Urinary β2 microglobulin, serum cystatin C, and creatinine clearance analyses were also studied. The median age was 11 years (4-21) and median remission time was 4.3 years (1.8-14.4). The cumulative dose of ifosfamide was 36 g. Glomerular filtration rate was decreased in 41.4% and urine β2 microglobulin levels and serum cystatin C levels were elevated in 31% of the patients. As the remission time increased, serum creatinine and cystatin C levels were also increased. The sensitivity for β2 microglobulin and cystatin C in demonstrating CRF was 35.2% and 23% and specificity was 33.2% and 50% respectively. The 24-hour urine NGAL cut-off level for demonstrating CRF was found to be 1.065 ng/mL/24 hours. The sensitivity and specificity for this cut-off value were 83% and 77%, respectively. NGAL levels were significantly higher in the study group as compared with the control group. Although ifosfamide treatment was suggested to be safe with no complication of renal failure under a dose of 80 g/m2, chronic renal failure and deficits in glomerular and tubular function could be seen when the remission time increased. Elevated NGAL levels may be a good option in determining CRF.

Patients with large, high-grade extremity soft tissue sarcoma (STS) are at high risk for both local and distant recurrence. RTOG 95-14, using a regimen of neoadjuvant interdigitated chemoradiotherapy with mesna, doxorubicin, ifosfamide, and dacarbazine followed by surgery and 3 cycles of adjuvant mesna, doxorubicin, ifosfamide, and dacarbazine, demonstrated high rates of disease control at the cost of significant toxicity (83% grade 4, 5% grade 5). As such, this regimen has not been widely adopted. Herein, we report our institutional outcomes utilizing a modified interdigitated chemoradiotherapy regimen, without dacarbazine, and current radiotherapy planning and delivery techniques for high-risk STS. Adults with large (≥5 cm; median, 12.9 cm), grade 3 extremity STS who were prospectively treated as part of our institutional standard of care from 2008 to 2016 are included. Neoadjuvant chemoradiotherapy consisted of 3 cycles of mesna, doxorubicin, and ifosfamide (MAI) and 44 Gy (22 Gy in 11 fractions between cycles of MAI) after which patients underwent surgical resection and received 3 additional cycles of MAI. Twenty-six patients received the MAI treatment protocol. At a median follow-up of 47.3 months, 23 (88.5%) patients are still alive. Three year locoregional recurrence-free survival, disease-free survival, and overall survival are 95.0%, 64.0%, and 95.0%, respectively. There have been no therapy-related deaths or secondary malignancies. The nonhematologic grade 4 toxicity rate was 7.7%. Neoadjuvant interdigitated MAI radiotherapy followed by resection and 3 cycles of adjuvant MAI has resulted in acceptable and manageable toxicity and highly favorable survival in patients at greatest risk for treatment failure.

The aim of this study was to develop topical self-microemulsifying drug delivery systems (SMEDDS) containing antitumor agents (bleomycin, cisplatin and ifosfamide) and to investigate their inhibitory potential in SMEDDS on human cervical cancer HeLa cells. The physicochemical properties of cytostatic drug loaded SMEDDS were characterized. The cytotoxicity of main components of SMEDDS was also investigated. Their IC50 values were determined. HeLa cells were treated by different concentrations of cisplatin, bleomycin and ifosfamide alone and in various SMEDDS. The inhibitory effect on cell growth was analyzed by MTT cell viability assay. Inflammation is a driving force that accelerates cancer development. The inhibitory effect of these antitumor agents has also been tested on HeLa cells in the presence of inflammatory mediators (IL-1-β, TNF-α) as an in vitro model of inflamed human cervix. Significant differences in the cytotoxicity of cytostatic drugs alone and in SMEDDS have been found in a concentration-dependent manner. The self-micro emulsifying system may potentiate the effectiveness of bleomycin, cisplatin and ifosfamide topically. The effect of SMEDDS containing antitumor agents was decreased significantly in the presence of inflammatory mediators. According to our experiments, the optimal SMEDDS formulation is 1:1:2:6:2 ratios of Isopropyl myristate, Capryol 90, Kolliphor RH 40, Cremophor RH40, Transcutol HP and Labrasol. It can be concluded that SMEDDS may increase the inhibitory effect of bleomycin, ifosfamide and cisplatin on human cervical cancer HeLa cells. Inflammation on HeLa cells hinders the effectiveness of SMEDDS containing antitumor agents. Our results might ensure useful data for development of optimal antitumor formulations.

Chemotherapy options for resistant advanced-stage sarcomas are limited and in most cases disappointing. In a phase II study, we treated 26 consecutive patients with refractory advanced sarcoma with ifosfamide and etoposide combination chemotherapy. All patients had received prior doxorubicin- and/or cyclophosphamide-based chemotherapies. Seventeen patients were male and 9 were female. The patients' median age was 35 years (range: 19-67 years). A total of 24 patients were eligible for evaluation of responses. Seven patients had a complete response (CR) (29.1%), 3 had a partial response (PR) (12.5%), 3 had stable disease (SD) (12.5%), and 11 had progressive disease (PD) (45.9%). An overall 41.6% objective response was achieved. Median time to treatment failure was 13.3 months. A total of 108 cycles of therapy were evaluable for evaluation of toxicity. Myelosuppression, observed in 55.5% of the treatment courses, was the major dose-limiting toxicity. Nausea and vomiting, seen in 64% of the courses, were the most important nonhematological side effects. Alopecia was almost universal. Hemorrhagic cystitis was observed in only 1 patient. We have concluded that the combination of ifosfamide, mesna, and etoposide is effective in advanced refractory sarcomas, and has acceptable toxicity.

Soft tissue sarcomas (STSs) are a group of rare tumors accounting for less than 1% of all adult malignant tumors, a heterogeneous group of more than 50 histological subtypes. Five percent to 30% of STS patients experience local recurrence and 10%-38% present with clinically detectable metastases. Doxorubicin either alone or in combination with ifosfamide has been used as first-line chemotherapy for advanced disease. After failure of first-line chemotherapy, high-dose ifosfamide, gemcitabine + docetaxel, and dacarbazine may be applicable, although high-level evidence is lacking. Trabectedin is a synthetic, marine-derived alkylating agent derived from the Caribbean tunicate, Ecteinascidia turbinata. Several clinical trials have shown that trabectedin has a favorable toxicity profile and is an alternative therapeutic option in adult patients with advanced STS who have not responded to treatment with doxorubicin and ifosfamide. Several clinical trials also recommend the 24-hour intravenous infusion every 3 weeks regimen. The most frequently reported grade 3/4 adverse events were neutropenia and elevated serum levels of AST/ALT. Steroid pretreatment is an effective way of reducing the extent of hepatotoxicity, and steroids are now given routinely before trabectedin administration. Further studies are ongoing to evaluate the efficacy and safety of combination therapy of trabectedin with other agents.

A prospective study of the effectiveness of ifosfamide as a single agent in the management of previously untreated patients with Evans stage IV neuroblastoma was undertaken. Eighteen children aged more than 1 year were treated with ifosfamide (IFX) 3 g/m2 daily for 2 days immediately after diagnosis and 3 weeks later. Treatment was continued with combination chemotherapy using vincristine, cyclophosphamide, cisplatinum and etoposide (OPEC) or a variant. Mesna (2-mercaptoethane sulphonate) was given to all patients during IFX treatment to prevent urotoxicity. Eight of the 18 patients (44%) responded to IFX. Nine had greater than 66% reduction in baseline tumor volume. Of 15 evaluable patients with raised pre-treatment urinary catecholamine excretion, six (40%) achieved greater than 50% reduction in pretreatment levels. Two of 10 patients evaluable for bone marrow response had complete clearance. Toxicity was mild in all patients. Upon completing 'first line' therapy, only four patients (22%) achieved a good partial remission (GPR) or complete response (CR). Median survival was 11 months. There was a lower rate of attaining GPR and shortened median survival in patients receiving phase II IFX before OPEC or variant, compared to patients with similar pre-treatment characteristics treated with OPEC from diagnosis in an earlier study.

High-dose chemotherapy with autologous stem cell rescue is commonly used for the treatment of relapsed germ cell tumors. We report the first case of delayed rhabdomyolysis with paclitaxel, ifosfamide, carboplatin, and etoposide regimen. We report a case of a 21-year-old African-American man diagnosed with relapsed non-seminomatous germ cell tumor who received high-dose chemotherapy with carboplatin and etoposide following TIGER trial arm B off-protocol. His course was complicated by muscle pain and rhabdomyolysis after cycle 4 on day +12 after infusion of autologous stem cells. To the best of our knowledge, this complication has not been reported with this regimen. A differential diagnosis of sepsis and neutropenic fever along with side effects of high-dose chemotherapy were considered, but based on the timing of events, it was concluded that the etiology of rhabdomyolysis is high-dose chemotherapy. Rhabdomyolysis was successfully treated with hydration and did not recur during subsequent cycle 5. Delayed rhabdomyolysis after high-dose chemotherapy with paclitaxel, ifosfamide, carboplatin, and etoposide regimen has not been previously reported and needs to be considered for preventive strategy and prompt diagnosis and treatment to avoid renal complications. Physicians should have a low threshold to check creatine kinase enzymes in patients with unexplained muscle pain or renal insufficiency after high-dose chemotherapy.

Renal Fanconi syndrome occurs in about 1-5% of all children treated with Ifosfamide (Ifo) and impairment of renal phosphate reabsorption in about 20-30% of them. Pathophysiological mechanisms of Ifo-induced nephropathy are ill defined. The aim has been to investigate whether Ifo metabolites affect the type IIa sodium-dependent phosphate transporter (NaPi-IIa) in viable opossum kidney cells. Ifo did not influence viability of cells or NaPi-IIa-mediated transport up to 1 mM/24 h. Incubation of confluent cells with chloroacetaldehyde (CAA) and 4-hydroperoxyIfosfamide (4-OH-Ifo) led to cell death by necrosis in a concentration-dependent manner. At low concentrations (50-100 microM/24 h), cell viability was normal but apical phosphate transport, NaPi-IIa protein, and -mRNA expression were significantly reduced. Coincubation with sodium-2-mercaptoethanesulfonate (MESNA) prevented the inhibitory action of CAA but not of 4-OH-Ifo; DiMESNA had no effect. Incubation with Ifosfamide-mustard (Ifo-mustard) did alter cell viability at concentrations above 500 microM/24 h. At lower concentrations (50-100 microM/24 h), it led to significant reduction in phosphate transport, NaPi-IIa protein, and mRNA expression. MESNA did not block these effects. The effect of Ifo-mustard was due to internalization of NaPi-IIa. Cyclophosphamide-mustard (CyP-mustard) did not have any influence on cell survival up to 1000 microM, but the inhibitory effect on phosphate transport and on NaPi-IIa protein was the same as found after Ifo-mustard. In conclusion, CAA, 4-OH-Ifo, and Ifo- and CyP-mustard are able to inhibit sodium-dependent phosphate cotransport in viable opossum kidney cells. The Ifo-mustard effect took place via internalization and reduction of de novo synthesis of NaPi-IIa. Therefore, it is possible that Ifo-mustard plays an important role in pathogenesis of Ifo-induced nephropathy.

We designed a phase I-II trial of three active agents, paclitaxel, ifosfamide, and vinorelbine, in advanced non-small-cell lung cancer (NSCLC) to: 1) define the dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of paclitaxel with filgrastim (G-CSF) support; and 2) determine the overall response rate and median survival of patients treated on this regimen. We treated cohorts of patients with stage IIIB or IV NSCLC with ifosfamide 1.2-1.6 g/m2/day x 3 and vinorelbine 20-25 mg/m2/day x 3 and escalating doses of paclitaxel at 100-175 mg/m2 on day 2 with G-CSF support on a 21-day cycle. One prior experimental single-agent chemotherapy regimen was allowed. Fifty-six patients, were enrolled on this trial: 27 on the phase I portion of the study and an additional 29 at the recommended phase II dose (RPTD). Thirteen patients had received prior chemotherapy. Paclitaxel doses of 175 mg/m2 and 150 mg/m2 produced dose-limiting myelosuppression, and the RPTD was determined to be paclitaxel 135 mg/m2 with ifosfamide 1.2 g/m2/day on days 1-3 and vinorelbine 20 mg/m2/ day on days 1-3 with G-CSF support. The overall response rate was 18%, with a median survival of 6.1 months. Six of 35 patients (17%) treated at the RPTD achieved a partial response to therapy. Grade IV neutropenia was observed in 19 of 35 patients at this dose, with eight patients suffering febrile neutropenia. This non-cisplatin-containing three-drug regimen has substantial toxicity and low activity in advanced NSCLC, and does not seem to improve on prior regimens. It is unclear whether the lack of efficacy relates to an antagonistic reaction between the specific drugs, administration schedule, or to subtherapeutic doses of the individual agents.

The ifosfamide, mesna and epirubicin (IMEpi) combination is administered to 16 patients having advanced metastatic breast carcinoma as second-line chemotherapy. We observed complete response in 6%, partial response in 44% (total overall response rate of 50%), stable disease in 12% and progressive disease in the remaining 38% of the patients. The median remission duration in responders was calculated to be 9.6 months. IMEpi regimen had a tolerable toxicity profile including alopecia, nausea and vomiting, microscopic hematuria, leukopenia and neurotoxicity in which serious complications necessitating discontinuation of the chemotherapy were not encountered. It might be concluded that IMEpi chemotherapy combination is an effective alternative among schedules in the management of patients with stage IV breast carcinoma without serious side effects.

Anthracycline and ifosfamide-based chemotherapy represents a widely used regimen both in early and advanced settings in soft tissue sarcoma (STS). Prophylaxis with granulocyte colony-stimulating factor (G-CSF) reduces the severity of chemotherapy-induced neutropenia. The aim of this study was to assess the efficacy and safety of biosimilar G-CSF in these patients. Between 2003 and 2013, 67 patients with soft tissue tumors under epirubicin and ifosfamide (EI) treatment receiving biosimilar filgrastim (Zarzio®), originator filgrastim (Granulokine®, Neupogen®), and lenograstim (only originator Myelostim®) as primary prophylaxis for a total of 260 cycles of therapy were retrospectively analyzed. Baseline patient characteristics were summarized in a propensity score (PS). The incidence of febrile neutropenia (FN) was 44.0 % in biosimilar filgrastim, 40.0 % in originator filgrastim, and 45.5 % in the lenograstim groups (p = 0.935). All grade and G4 neutropenia were similar in the three groups with the same safety profile. The use of biosimilar filgrastim achieved cost savings of €225.25 over originator filgrastim and €262.00 over lenograstim. Biosimilar G-CSF was effective in preventing FN and in reducing the need for hospitalization in STS patients undergoing EI treatment. It also proved comparable to its reference products from both a clinical and cost-effective standpoint.

A randomized Phase II/III trial was planned to commence in March 2014. Perioperative chemotherapy with adriamycin plus ifosfamide is the current standard treatment for T2bN0M0 high-grade non-round cell soft tissue sarcoma. The purpose of this study is to confirm the non-inferiority of perioperative chemotherapy with gemcitabine and docetaxel to adriamycin plus ifosfamide for patients with T2bN0M0 or any TN1M0 non-round cell soft tissue sarcoma in the extremities and body wall. A total of 140 patients will be accrued from 28 Japanese institutions over 6 years. The primary endpoint in the Phase II part is the proportion of completion of pre-operative chemotherapy without progressive disease and overall survival in the Phase III part. The secondary endpoints are progression-free survival, response rate of pre-operative chemotherapy, pathological response rate, proportion of preservation of diseased limbs, disease control rate and proportion of adverse events.

The main objective was to evaluate the impact of two methods aiming at reducing hazardous drug environmental contamination: the centralization of the priming of IV tubing in the pharmacy and the use of a closed-system transfer device. The secondary objective was to evaluate the satisfaction of pharmacy technicians using a survey. Sites in the hematology-oncology satellite pharmacy and care unit were analyzed for the presence of cyclophosphamide, ifosfamide and methotrexate before and after the centralization of the priming of IV tubing in the pharmacy and before and after using a closed-system transfer device. The limits of detection for cyclophosphamide, ifosfamide and methotrexate were, respectively, of 0.0015 ng/cm(2), 0.0012 ng/cm(2) and 0.0060 ng/cm(2). The pharmacy technician satisfaction was evaluated using a questionnaire. A total of 225 samples was quantified. After the centralization of priming in the pharmacy, no significant difference was found in the proportion of positive samples for cyclophosphamide, ifosfamide and methotrexate. Traces of cyclophosphamide found on the floor in patient care areas was significantly reduced (median[min-max] 0.08[0.06-0.09]ng/cm(2) vs. 0.03[0.02-0.05], p < 0.0001). After using a closed-system transfer device, a significant difference was found for the proportion of cyclophosphamide positive samples (15/45(33%) vs. 0/45(0%), p < 0.0001), but no significant difference was found for ifosfamide (12/45(27%) vs. 5/45(11%), p = 0.059) and methotrexate (1/45(2%) vs. 2/45(4%), p = 0.557). Pharmacy technicians raised issues following the centralization of priming (e.g. workload) and the use of closed-system transfer devices (e.g. spills, particles, workload and handling difficulties). The centralization of the priming of IV tubing in the pharmacy reduced floor contamination in patient care areas without increasing surface contamination in the pharmacy. Closed-system transfer devices reduced contamination in pharmacy, but handling issues were raised by pharmacy technicians. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

This study was conducted to compare the efficacy and safety of ifosfamide plus etoposide plus platinum (IEP) to that of etoposide plus platinum (EP) in patients with previously untreated small-cell lung cancer (SCLC). The Cochrane Library, Embase, MEDLINE and Chinese Biomedical Literature databases were searched to identify all randomized controlled trials comparing IEP to EP in patients with histologically proven SCLC. Two investigators independently assessed the quality of the relevant trials and extracted data. We analyzed the data using Review Manager software, version 4.2.8. A total of 4 trials with 447 previously untreated SCLC patients were included in this meta-analysis. The results of the meta-analysis indicated that there were no significant differences in the overall response [relative risk (RR) = 1.07, 95% confidence interval (CI): 0.97-1.19], 1-year survival rate (RR=1.22, 95% CI: 0.96-1.55) and 2-year survival rate (RR=1.52, 95% CI: 0.75-3.07) between the IEP and EP regimens. However, there were significant differences between the IEP and EP regimens regarding the incidence of grade 3/4 neutropenia (RR=1.52, 95% CI: 1.07-2.17) and grade 3/4 vomiting (RR=1.78, 95% CI: 1.02-3.11). In conclusion, our results suggested that IEP is not superior to EP regimen for the treatment of previously untreated SCLC, whereas the IEP regimen is associated with more severe hematological and gastrointestinal toxicities compared to EP. Therefore, the use of ifosfamide in multimodality treatment regimens requires further investigation. PMID:25798279

A total of 4 trials with 447 previously untreated SCLC patients were included in this meta-analysis. The results of the meta-analysis indicated that there were no significant differences in the overall response [relative risk (RR) = 1.07, 95% confidence interval (CI): 0.97-1.19], 1-year survival rate (RR=1.22, 95% CI: 0.96-1.55) and 2-year survival rate (RR=1.52, 95% CI: 0.75-3.07) between the IEP and EP regimens. However, there were significant differences between the IEP and EP regimens regarding the incidence of grade 3/4 neutropenia (RR=1.52, 95% CI: 1.07-2.17) and grade 3/4 vomiting (RR=1.78, 95% CI: 1.02-3.11). In conclusion, our results suggested that IEP is not superior to EP regimen for the treatment of previously untreated SCLC, whereas the IEP regimen is associated with more severe hematological and gastrointestinal toxicities compared to EP. Therefore, the use of ifosfamide in multimodality treatment regimens requires further investigation.

The antitumor drug, ifosfamide (IFO), requires activation by cytochrome P450 (CYP) to form the active metabolite, 4-hydroxyisfosfamide (4-OHIFO), leading to toxic by-products at high dose. In order to overcome these drawbacks, preactivated ifosfamide derivatives (RXIFO) were designed to release 4-OHIFO without CYP involvement. A high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed for the simultaneous quantification of 4-OHIFO, IFO and four derivatives RXIFO in mouse plasma using multiple reaction monitoring. Because of its instability in plasma, 4-OHIFO was immediately converted to the semi-carbazone derivative, 4-OHIFO-SCZ. For the six analytes, the calibration curves were linear from 20 to 5000ng/mL in 50μL plasma and the lower limit of quantitation was determined at 20ng/mL with accuracies within ±10% of nominal and precisions less than 12%. Their recoveries ranged from 62 to 96% by using liquid-liquid extraction. With an improved assay sensitivity compared to analogues, the derivative 4-OHIFO-SCZ was stable in plasma at 4°C for 24h and at -20°C for three months. For all compounds, the assay was validated with accuracies within ±13% and precisions less than 15%. This method was applied to a comparative pharmacokinetic study of 4-OHIFO from IFO and three derivatives RXIFO in mice. This active metabolite was produced by some of the novel conjugates with good pharmacokinetic properties. Copyright © 2015 Elsevier B.V. All rights reserved.

This paper reports a typical synthesis of a nanocomposite of functionalized graphene quantum dots and imprinted polymer at the surface of screen-printed carbon electrode using N-acryloyl-4-aminobenzamide, as a functional monomer, and an anticancerous drug, ifosfamide, as a print molecule (test analyte). Herein, graphene quantum dots in nanocomposite practically induced the electrocatalytic activity by lowering the oxidation overpotential of test analyte and thereby amplifying electronic transmission, without any interfacial barrier in between the film and the electrode surface. The differential pulse anodic stripping signal at functionalized graphene quantum dots based imprinted sensor was realized to be about 3- and 7-fold higher as compared to the traditionally made imprinted polymers prepared in the presence and the absence of graphene quantum dots (un-functionalized), respectively. This may be attributed to a pertinent synergism in between the positively charged functionalized graphene quantum dots in the film and the target analyte toward the enhancement of electro-conductivity of the film and thereby the electrode kinetics. In fact, the covalent attachment of graphene quantum dots with N-acryloyl-4-aminobenzamide molecules might exert an extended conjugation at their interface facilitating electro conducting to render the channelized pathways for the electron transport. The proposed sensor is practically applicable to the ultratrace evaluation of ifosfamide in real (biological/pharmaceutical) samples with detection limit as low as 0.11ngmL -1 (S/N=3), without any matrix effect, cross-reactivity, and false-positives.

[Indication of chemotherapy according to histological type of musculoskeletal sarcomas].

In high-grade musculoskeletal sarcomas, adjuvant chemotherapy is often performed to prevent distant metastases. As the efficacy of chemotherapy varies according to the histological type of sarcoma, its indication is determined according to the histological type and the stage. Prognoses are poor in patients with osteosarcoma, Ewing's sarcoma, or rhabdomyosarcoma, when surgery alone is performed. However, because these sarcomas are chemosensitive, their prognoses are improved with adjuvant chemotherapy, so it is absolutely necessary. Drugs commonly used for osteosarcoma include adriamycin, cisplatin, methotrexate, vincristine, and ifosfamide. For Ewing's sarcoma and rhabdomyosarcoma, vincristine, actinomycin-D, cyclophosphamide, etoposide, and ifosfamide are commonly used. On the other hand, the efficacy of chemotherapy is unclear in most of the non-round cell sarcomas, e. g., malignant fibrous histiocytoma, pleomorphic liposarcoma, and leiomyosarcoma, so adjuvant chemotherapy is relatively indicated and often performed preoperatively. The efficacy is evaluated by reduction of the tumor volume as a surrogate marker. Postoperative chemotherapy is performed when the preoperative chemotherapy is effective. Nowadays, several kinds of antitumor agents are usually used for non-round cell sarcomas, and many authors have reported various kinds of regimens and their clinical results. Among them, the key drugs are adriamycin and ifosfamide. Recently, taxanes and gemcitabine are sometimes used. For chemoresistant sarcomas, e. g., chondrosarcoma, chordoma, alveolar soft part sarcoma, chemotherapy is rarely indicated, even if the tumor is histologically high grade and large. Low-grade musculoskeletal sarcomas, e. g., low-grade chondrosarcoma, central low-grade osteosarcoma, parosteal osteosarcoma, well-differentiated liposarcoma, and dermatofibrosarcoma protuberans, are well cured only by surgical excision, and adjuvant chemotherapy is therefore not indicated. Superficially-located, small-size non-round cell sarcomas, even though histologically high grade, are well healed only by surgical excision, and adjuvant chemotherapy is rarely indicated.

Local control rate for inflammatory breast cancer (IBC) is < 50% with standard chemotherapy-radiotherapy regimen. Nineteen women (age range 40-65, median 50 years) with IBC (18 patients) or with a primary tumour of > 10 cm (one patient) received a novel treatment comprising hyperfractionated radiotherapy (HFRT) sandwiched between two cycles of infusional chemotherapy using vincristine, ifosfamide and epirubicin (VIE). The primary endpoint was local control. VIE was continuously infused for six weeks via a Hickman's line using a Deltec CADD-1 ambulatory pump. Ifosfamide (3 gm/m2) mixed with equi-dose mesna was infused for seven days and alternated every week with an infusion of epirubicin (50 mg/m2) mixed with vincristine (1.5 mg/m2). HFRT consisted of 1.5 Gy twice daily for 34 frct (51 Gy) followed by a boost of 15 Gy in 10 frct. The total treatment time was less than 22 weeks. Median follow-up was 37 months. Local control rate was 58%. Three patients failed to respond initially and five relapsed in the breast at a median time of 36.8 months. Median overall and disease-free survival was 18 and 25.3 months respectively. Toxicity from VIE was minimal (WHO gd 3 emesis--two patients, gd 3 mucositis--one patient, neutropenic sepsis--three patients). Radiotherapy caused moist desquamation in 17/19 patients. Twenty-four central lines were complicated by seven line infections, three thromboses, and one extravasation. The local control rate of 58% with VIE + HFRT appears similar to reported chemoradiotherapy regimen, although the treatment time of 22 weeks is much shorter than other regimens which take up to 12 months. Toxicity is acceptable. Hickman-related complications need to be reduced. The study is ongoing.

Phase II trial in metastatic urothelial carcinoma using a novel combination chemotherapy regimen consisting of vinblastine, ifosfamide, and gallium nitrate (VIG). Twenty-seven patients were entered onto this phase II study. Dosages were vinblastine 0.11 mg/kg days 1 and 2, ifosfamide 1.2 gm/m2 days 1 through 5 (with mesna), and gallium 300 mg/m2 as a 24-hour infusion days 1 through 5, with calcitriol (1,25-dihydroxycholecalciferol) 0.5 microgram/d orally starting 3 days before each course (except the first) and continuing throughout gallium administration, plus recombinant human granulocyte colony-stimulating factor (rhG-CSF) (filgrastim) 5 micrograms/kg/d days 7 through 16. Courses were repeated every 21 days for a maximum of six cycles. The major toxicity was granulocytopenia. Fifteen patients (55.6%) had grade 3 or 4 granulocytopenia, including eight patients with granulocytopenic fevers. Eleven patients had grade 3 or 4 anemia and four had grade 3 or 4 nephrotoxicity, which was reversible. Other grade 3 to 4 toxicities included hypocalcemia (three patients), thrombocytopenia (two), encephalopathy (one), and temporary blindness (one). There was one treatment-related mortality. Toxicity was more severe in patients older than 70 years and those with prior pelvic irradiation, prior cisplatin adjuvant therapy, or prior nephrectomy. We now decrease VIG by 20% in this patient population. Eighteen patients (67%) achieved an objective response, including 11 (41%) who attained a disease-free status (five with VIG alone and six with subsequent surgery). Median duration of remission was 20 weeks, with five patients still in remission at 22+ to 56+ weeks. VIG combination chemotherapy is very active in patients with metastatic urothelial carcinoma. Toxicity was significant but manageable.

Purpose: To evaluate the effectiveness of concurrent chemoradiation therapy (CCRT) with 40 Gy followed by consolidation chemotherapy for localized extranodal natural killer (NK)/T-cell lymphoma (ENKTL), nasal type. Methods and Materials: From August 2004 to August 2012, 62 patients with newly diagnosed stage IE to IIE ENKTL underwent CCRT followed by consolidation chemotherapy. The median RT dose was 40 Gy. Cisplatin, 30 mg/m{sup 2}, was administered weekly during the RT course. Responders to CCRT were encouraged to undergo consolidation chemotherapy. Three different consolidation chemotherapy regimens were used consecutively: VIPD (etoposide, ifosfamide, cisplatin, and dexamethasone); VIDL (etoposide, ifosfamide, and dexamethasone followed by intramuscular injection ofmore » L-asparaginase); and MIDLE (methotrexate, etoposide, ifosfamide, mesna, and L-asparaginase). Results: The median follow-up period was 49 months (range 8-112). After completion of CCRT, 56 patients (90.3%) had a complete response, 4 (6.4%) had a partial response, 1 (1.6%) had stable disease, and 1 patient (1.6%) had progressive disease (PD). Consolidation chemotherapy was recommended to 61 patients, after excluding the patient with PD, but was actually delivered to 58. Of these 58 patients, 56 (96.5%) had a complete response and 2 (3.5%) had PD. During the follow-up period, 17 patients (including 3 with PD) experienced progression. The median interval to progression was 11 months (range 1-61). Local failure developed in 6 patients, of whom, 2 had developed progression outside the RT field. For all patients, the 3-year overall survival, progression-free survival, and local control rates were 83.1%, 77.1%, and 92.4%, respectively. Grade ≥3 nonhematologic toxicity developed in only 3 patients (4.8%). Conclusions: Excellent clinical outcomes were achieved using CCRT with 40 Gy followed by consolidation chemotherapy. Additional investigation, however, is warranted to confirm our findings.« less

Good local control of high-grade non-small round cell soft tissue sarcomas (NSRCSTSs) has been achieved with significant advances in surgical techniques and radiotherapy. However, the role of chemotherapy remains controversial. Our aim was to investigate the efficacy, feasibility and adverse effects of neoadjuvant and adjuvant chemotherapy with modified mesna, adriamycin, ifosfamide and dacarbazine (MAID) regimen for NSRCSTSs. We conducted a retrospective review of 40 consecutive patients (29 men, 11 women; median age 47 years) with high-grade NSRCSTSs treated in two referral centers between 2004 and 2009 (median follow-up 38.5 months). Patients with distant or nodal metastases at diagnosis were excluded. The regimen consisted of ifosfamide 2,500 mg/m(2)/6 h (days 1-3), mesna 2,500 mg/m(2)/6 h (days 1-3), tetrahydropyranyl adriamycin 20 mg/m(2)/0.5 h (days 1-3), and dacarbazine 300 mg/m(2)/1 h (days 1-3). Among the 26 evaluable patients, there were 8 with a partial response, 15 with stable disease, and 3 with progressive disease. Two- and 5-year overall survival rates were 92 and 86%, respectively, and corresponding disease-free survival rates were 80 and 77%. All relapses were metastases without local recurrence. Grade 3-4 neutropenia, anemia and thrombocytopenia were observed in 38, 18, and 21 patients, respectively. No serious infectious complications occurred due to the administration of granulocyte colony-stimulating factor and prophylactic antibiotics. No other life-threatening serious adverse events were observed. The modified MAID regimen achieved a better outcome with less serious adverse events than previously reported and is a potential option in the management of NSRCSTSs. Further evaluation with long-term follow-up is required.

Paclitaxel, ifosfamide, cisplatin (TIP) is commonly used as salvage for malignant germ cell tumors (MGCT) in adults; however, additional administration of cisplatin at a young age could cause significant short- and long-term toxicities in a group of patients with high expected salvage. Because carboplatin has been shown to be effective in pediatric MGCT with less toxicity, the TIP regimen was modified by substituting carboplatin for cisplatin. The Children's Oncology Group conducted a phase II trial between November 2007 and June 2011 evaluating "TIC" (paclitaxel 135 mg/m 2 /day Day 1, ifosfamide 1,800 mg/m 2 /dose Days 1-5 and carboplatin with AUC 6.5 Day 1) in children < 21 years with relapsed MGCT. The endpoint of the trial was response after two cycles, incorporating RECIST response and marker decline. Twenty patients (12 male, median age 13.5 years) were enrolled. Seventeen patients had tumor markers ≥10 times above normal. After two cycles, by RECIST criteria, 8 patients achieved a partial response (response rate 40%), 10 had stable disease, and 2 had progressive disease. A ≥ 1 log reduction was achieved in 10/17 patients (58.8%) with elevated markers. By study defined criteria, combining response by RECIST and marker decline, the response rate was 44%. TIC is active in relapsed pediatric MGCT and should be considered for salvage therapy in children. In adolescents and older adults with relapse MGCT, TIP or high-dose chemotherapy with stem cell remain the standard therapy. © 2018 Wiley Periodicals, Inc.

Primary spinal germ cell tumors are rare, and spinal nongerminomatous germ cell tumors represent an even rarer subset for which no standard therapy has been established. The authors report the case of a 24-year-old woman with multifocal primary spinal germ cell tumors scattered from T-12 to L-5 that consisted of yolk sac tumor and mature teratoma. After diagnostic partial resection, the patient was treated with 30 Gy of craniospinal irradiation and 30 Gy of local spinal irradiation, followed by 8 courses of chemotherapy based on ifosfamide, cisplatin, and etoposide (ICE). Salvage surgery was also performed for residual mature teratoma components after the third course of ICE chemotherapy. Chemotherapy was continued after the operation, but ifosfamide was entirely eliminated from the ICE regimen because severe myelosuppression was observed after previous courses. The patient remains recurrence free as of more than 5 years after the completion of chemotherapy. This case suggests that this treatment strategy is an effective option for primary spinal yolk sac tumor.

Tandem mass spectrometric analysis of cyclophosphamide, ifosfamide and their metabolites.

A detailed multi-stage (MSn) fragmentation study of cyclophosphamide (CP), ifosfamide (IF) and their major metabolites, using an ion-trap mass spectrometer and a Q-TOF mass spectrometer, was performed with the aid of specifically deuterium-labeled analogs. The analytes showed good responses in positive-ion electrospray mass spectrometry as [MH]+ ions. Tandem mass spectra revealed a wealth of structurally specific ions, allowing characterization of the fragmentation pathways of these analytes. The major fragmentation pathways of the protonated CP and IF are elimination of ethylene from C5 and C6 of 1,3,2-oxazaphosphorine-2-oxide via a McLafferty rearrangement, and cleavage of the P-N bond. However, their activated 4-OOH and 4-OH metabolites primarily underwent hydrogen peroxide elimination and dehydration, respectively, followed by fragmentation pathways similar to those of CP and IF. These results should prove useful in structural elucidation of future analogs of CP and IF, and/or of their metabolites. Copyright (c) 2005 John Wiley & Sons, Ltd.

Twenty patients with advanced sarcomas entered a pilot study with ifosfamide (IF) and mercaptoethane sulfonate sodium (Mesna) as a second-line treatment for six planned cycles. All patients had received prior doxorubicin- and cyclophosphamide-based chemotherapies. IF was administered at a dose of 3 g/m2 given as continuous intravenous infusion for 24 hr on day 1-5 with Mesna. In the absence of disease progression, chemotherapy was planned to be repeated every 4 weeks for six consecutive cycles. Following chemotherapy, only 2 patients (11%) achieved partial response with response durations of 6 and 9 months. There was no complete response. When considered for only high-grade tumors, the response rate reached up to 22%. Toxicity was reported for 48 cycles and the dose-limiting toxicities were myelosuppression (22%) and encephalopathy (17%). Chemotherapy protocol was changed after two or three courses in 16 patients with stable or progressive disease. IF/Mesna chemotherapy at this dose and schedule was not found to be very promising in refractory sarcomas as a second-line chemotherapy.

Preclinical models that mimic pathological and molecular features of solitary fibrous tumour (SFT) represent an important tool to select effective regimes and novel compounds to be tested in the clinic. This study was aimed at developing two preclinical models of SFT, assessing their predictive value in the clinic and selecting potential novel effective treatments. Two dedifferentiated-SFT (D-SFT) models obtained from patients' biopsies were grown in immunodeficient mice. The antitumour activity on these models of doxorubicin, dacarbazine (DTIC), ifosfamide (monotherapy or combination), trabectedin and eribulin was tested. Twelve SFT patients were treated with doxorubicin and DTIC. Response by RECIST, progression-free survival and overall survival were retrospectively evaluated, distinguishing malignant-SFT (M-SFT) and D-SFT. Two D-SFT patient-derived xenografts (PDXs) that represent the first available preclinical in vivo models of SFT were developed and characterised. Doxorubicin/DTIC, DTIC/ifosfamide, doxorubicin/ifosfamide combinations consistently induced better antitumour activity than the single-agents. Particularly, doxorubicin/DTIC combination caused a max tumour volume inhibition >80% in both models. Doxorubicin/DTIC combo showed activity also in the case-series. Best RECIST responses were: 6 responses (M-SFT = 2 of 7, D-SFT = 4 of 5), 1 stable disease, 5 progressions, with a 6-month median progression-free survival (M-SFT = 6, D-SFT = 10 months). The PDXs were very sensitive to trabectedin and eribulin. Doxorubicin plus DTIC combination was effective in our two D-SFT mice models and appeared to be active also in the clinic, especially in high-grade D-SFT patients. Among additional drugs tested in the PDXs, trabectedin and eribulin were highly effective, providing a rational to test these drugs in D-SFT patients. Copyright © 2017 Elsevier Ltd.

One half of high-risk germ cell tumor (HRGCT) patients relapse after standard chemotherapy. This phase II study evaluated prospectively the toxicity and efficacy in first-line of the paclitaxel-ifosfamide-cisplatin combination (TIP) in HRGCT patients and tried to identify biomarkers that may allow patient-tailored treatments. Between October 1997- September 2000, 28 chemo-naive HRGCT patients were enrolled. Patients received 4 cycles of TIP (paclitaxel 175 mg/m(2) day 1/; ifosfamide 1.2 g/m(2)/day, days 1-5; Mesna 1.2 g/m(2)/day, days 1-5; and cisplatin 20 mg/m(2)/day, days 1-5 every 3 weeks). A non-randomized comparison was made between HRGCT patients treated in the same period with first-line TIP and bleomycin-etoposide-cisplatin (BEP) (28 patients vs 20). In 17 HRGCT patients treated between 1998-2006, ERCC1, Topoisomerase 1 and 2A, p53 and HER-2 expression was retrospectively analysed by immunohistochemistry (IHC) (7 patients with TIP, 10 with BEP), and correlations were made with response to chemotherapy and survival. With a median follow-up of 72 months [range 48+...89+], 5-year disease free survival (DFS) was 55%, with 95% CI 36-72, and the overall survival (OS) was 63%, with 95% CI 44-78. In June 2015, with a median follow-up of 196.47 months (range 177.30-209.27) (>15 years), 12 [%?] patients were alive and disease-free, and 16 [%?] had died (12 specific causes). There was no significant correlation between the expression of ERCC1, Topoisomerase 1 and 2A, HER-2 and p53 and response to treatment. Long-term follow-up showed no difference in OS between TIP vs BEP as first-line therapy. Both regimens had mild toxicity.

Forty-seven previously untreated patients with histologically or cytologically proven non-small cell lung cancer were treated with ICE (ifosfamide/cisplatin/etoposide). Patients received ifosfamide 4 g/m2 with mesna uroprotection on day 1, and cisplatin 25 mg/m2/d and etoposide 100 mg/m2/d on days 1, 2, and 3; courses were repeated every 28 days. Premedication with prochlorperazine, dexamethasone, and high-dose metoclopramide was given to prevent nausea; lorazepam was added on days 2 and 3 only. Thirty-four men and 13 women (median age, 60 years) received a total of 146 treatment cycles. One patient had stage IIIA disease, seven had IIIB disease, and 39 had hematogenous metastases. Forty-six patients were evaluable for response and toxicity. One patient suffered a myocardial infarction on day 7 that was judged unrelated to treatment. Two patients suffered early death from toxicity and have been classified as nonresponders. Three patients achieved complete response (median, 42+ weeks) and 14 patients achieved partial response (median, 29+ weeks; range, 10 to 82+), for an overall response rate of 37% (95% confidence limits, 23% to 51%). The median survival of the entire group is 26 weeks (1 to 82+). The median nadir granulocyte count was 0.275 x 10(9)/L (range, 0 to 2.3 x 10(9)/L), and there were 14 episodes (in 11 patients) or neutropenia-associated fever, one of which resulted in death. Seven of these patients had not had the required protocol dose reduction for nadir neutrophil count in the preceding cycle. The median nadir platelet count was 120 x 10(9)/L (range, 13 to 385 x 10(9)/L), and three patients required platelet transfusions. Eleven patients had RBC transfusions. Only ten patients had grade 2 gastrointestinal toxicity. Five patients had microscopic hematuria, and one patient had central nervous system toxicity.

Occurrence and fate of the cytostatic drugs cyclophosphamide and ifosfamide in wastewater and surface waters.

The two oxazaphosphorine compounds cyclophosphamide and ifosfamide are important cytostatic drugs used in the chemotherapy of cancer and in the treatment of autoimmune diseases. Their mechanism of action, involving metabolic activation and unspecific alkylation of nucleophilic compounds, accounts for genotoxic effects described in the literature and is reason for environmental concern. The occurrence and fate of cyclophosphamide and ifosfamide were studied in wastewater treatment plants (WWTPs) and surface waters in Switzerland, using a highly sensitive analytical method based on solid-phase extraction and liquid chromatography tandem mass spectrometry. The compounds were detected in untreated and treated wastewater at concentrations of <0.3-11 ng/L, which corresponded well with concentrations predicted from consumption data and typical renal excretion rates. Weekly loads determined in influent and effluent wastewater were comparable and suggested a high persistence in WWTPs. Furthermore, no degradation was observed in activated sludge incubation experiments within 24 h at concentrations of approximately 100 ng/L. Processes that may be relevant for elimination in natural waterbodies were studied with a set of incubation experiments in the laboratory. After extrapolation to natural conditions in surface waters, a slow dark-chemical degradation (half-lives on the order of years) is the most important transformation process. Degradation by photochemically formed HO* radicals may be of some relevance only in shallow, clear, and nitrate-rich waterbodies but could be further exploited for elimination of these compounds by advanced oxidation processes, i.e., in a treatment of hospital wastewater. In surface waters, concentrations ranged from < or =50 to 170 pg/L and were thus several orders of magnitude lower than the levels at which acute ecotoxicological effects have been reported in the literature (mg/L range). However, due to a lack of studies on chronic effects on aquatic organisms and data on occurrence and effects of metabolites, a final risk assessment cannot be made.

Purpose Paclitaxel, ifosfamide, and cisplatin (TIP) achieved complete responses (CRs) in two thirds of patients with advanced germ cell tumors (GCTs) who relapsed after first-line chemotherapy with cisplatin and etoposide with or without bleomycin. We tested the efficacy of first-line TIP in patients with intermediate- or poor-risk disease. Patients and Methods In this prospective, multicenter, single-arm phase II trial, previously untreated patients with International Germ Cell Cancer Collaborative Group poor-risk or modified intermediate-risk GCTs received four cycles of TIP (paclitaxel 240 mg/m2 over 2 days, ifosfamide 6 g/m2 over 5 days with mesna support, and cisplatin 100 mg/m2 over 5 days) once every 3 weeks with granulocyte colony-stimulating factor support. The primary end point was the CR rate. Results Of the first 41 evaluable patients, 28 (68%) achieved a CR, meeting the primary efficacy end point. After additional accrual on an extension phase, total enrollment was 60 patients, including 40 (67%) with poor risk and 20 (33%) with intermediate risk. Thirty-eight (68%) of 56 evaluable patients achieved a CR and seven (13%) achieved partial responses with negative markers (PR-negative) for a favorable response rate of 80%. Five of seven achieving PR-negative status had seminoma and therefore did not undergo postchemotherapy resection of residual masses. Estimated 3-year progression-free survival and overall survival rates were 72% (poor risk, 63%; intermediate risk, 90%) and 91% (poor risk, 87%; intermediate risk, 100%), respectively. Grade 3 to 4 toxicities consisted primarily of reversible hematologic or electrolyte abnormalities, including neutropenic fever in 18%. Conclusion TIP demonstrated efficacy as first-line therapy for intermediate- and poor-risk GCTs with an acceptable safety profile. Given higher rates of favorable response, progression-free survival, and overall survival compared with prior first-line studies, TIP warrants further study in this population. PMID:27185842

Comparative pharmacokinetics of ifosfamide, 4-hydroxyifosfamide, chloroacetaldehyde, and 2- and 3-dechloroethylifosfamide in patients on fractionated intravenous ifosfamide therapy.

The initial metabolism of the oxazaphosphorine cytostatic ifosfamide (IF) consists of two different pathways: ring oxidation at carbon-4 forms the cytostatically active metabolite 4-hydroxyifosfamide (4-OH-IF, "activated ifosfamide"), whereas side-chain oxidation with liberation of the presumably neurotoxic compound chloroacetaldehyde (CAA) that may also be responsible for IF-associated nephrotoxicity results in the formation of the cytostatically inactive metabolites 2-dechloroethylifosfamide (2-DCE-IF) and 3-dechloroethylifosfamide (3-DCE-IF). The pharmacokinetics of IF and its metabolites were investigated in 11 patients with bronchogenic carcinoma receiving IF on a 5-day divided-dose schedule (1.5 g/m2 daily). Blood samples were drawn on days 1 and 5 for up to 24 h after the start of the IF infusion. IF, 2-DCE-IF, and 3-DCE-IF were simultaneously quantified by gas chromatography (GC) with an NIP flame-ionization detector (NPFID), CAA was determined by GC with an electron-capture detector (ECD), and the highly unstable compound 4-OH-IF was measured using a high-performance liquid chromatography (HPLC) assay with fluorometric detection of 7-OH-quinoline, which is formed by the condensation of 4-OH-IF-derived acrolein with m-aminophenol. As compared with the values obtained on day 1, on day 5 the terminal half-life and AUC values determined for IF were reduced by 30% (6.36 vs 4.06 h and 1781 vs 1204 nmol h ml-1, respectively), whereas the maximal concentration (Cmax) values were not affected significantly (199.1 vs 181.1 nmol ml-1). This known phenomenon is explained by autoinduction of hepatic IF metabolism and was paralleled by increased metabolite levels. The mean Cmax values determined for 4-OH-IF, CAA, 3-DCE-IF, and 2-DCE-IF (on day 1/on day 5) were 1.51/2.59, 2.69/4.85, 12.9/26.5, and 8.6/16.7 nmol ml-1, respectively. The corresponding AUC values were 11.3/16.5, 30.3/34.3, 146/354, and 111/209 nmol h ml-1, respectively. As calculated by intraindividual comparison, the mean Cmax (day 5): Cmax (day 1) ratios for 4-OH-IF, CAA, 3-DCE-IF, and 2-DCE-IF were 1.94*, 2.05*, 2.52*, and 2.33*, respectively; the corresponding AUC (day 5): AUC (day 1) ratios were 1.51*, 1.29, 2.34*, and 2.23*, respectively (* P < 0.05). These data reveal that during fractionated-dose IF therapy the cancerotoxic effect of the drug increases. If the assumed role of CAA in IF-associated neurotoxicity and nephrotoxicity is a dose-dependent phenomenon, the probability of developing these side effects would also increase during prolonged IF application.

Fifty-one patients with non-Hodgkin's lymphoma refractory or relapsing after CHOP-like regimen, underwent a salvage chemotherapy by VPH: etoposide 100 mg/m2/d, D1 to D3, cisplatin 20 mg/m2/d, D1 to D5, ifosfamide 1 g/m2/d D1 to D5, mesna 1.2 g/m2/d D1 to D5, every 4 weeks. Among 46 evaluable patients for efficacy, 21 (45.6%) achieved complete or partial response according to WHO criteria and 25 (54.3%) failed, while five cases (9.8% of all patients) were not evaluable (two initial complete remission before VPH, two early toxic deaths and one confusional syndrome). Thirty-five patients (68.6%) died of lymphoma, three (5.8%) of acute toxicity and 13 (25.5%) are alive: five in complete remission. The toxicity is mainly myelo-suppression, digestive and renal but could be managed as usually. Although the follow-up is short, this regimen appears effective in these circumstances after CHOP failure but it should be used early, before overt chemoresistance. It does not hinder a bone marrow transplantation programme.

This work presents a study about the elimination of anticancer drugs, a group of pollutants considered recalcitrant during conventional activated sludge wastewater treatment, using a biological treatment based on the fungus Trametes versicolor. A 10-L fluidized bed bioreactor inoculated with this fungus was set up in order to evaluate the removal of 10 selected anticancer drugs in real hospital wastewater. Almost all the tested anticancer drugs were completely removed from the wastewater at the end of the batch experiment (8 days) with the exception of Ifosfamide and Tamoxifen. These two recalcitrant compounds, together with Cyclophosphamide, were selected for further studies to test their degradability by T. versicolor under optimal growth conditions. Cyclophosphamide and Ifosfamide were inalterable during batch experiments both at high and low concentration, whereas Tamoxifen exhibited a decrease in its concentration along the treatment. Two positional isomers of a hydroxylated form of Tamoxifen were identified during this experiment using a high resolution mass spectrometry based on ultra-high performance chromatography coupled to an Orbitrap detector (LTQ-Velos Orbitrap). Finally the identified transformation products of Tamoxifen were monitored in the bioreactor run with real hospital wastewater. Copyright © 2015 Elsevier Ltd. All rights reserved.

A marginal interaction between sex and the type of alkylating agent was observed for event-free survival in the Euro-EWING99-R1 randomized controlled trial (RCT) comparing cyclophosphamide and ifosfamide in Ewing sarcoma. To further evaluate this interaction, we performed an individual patient data meta-analysis of RCTs assessing cyclophosphamide versus ifosfamide in any type of cancer. A literature search produced two more eligible RCTs (EICESS92 and IRS-IV). The endpoints were progression-free survival (PFS, main endpoint) and overall survival (OS). The hazard ratios (HRs) of the treatment-by-sex interaction and their 95% confidence interval (95% CI) were assessed using stratified multivariable Cox models. Heterogeneity of the interaction across age categories and trials was explored. We also assessed this interaction for severe acute toxicity using logistic models. The meta-analysis comprised 1,528 pediatric and young adult sarcoma patients from three RCTs: Euro-EWING99-R1 (n = 856), EICESS92 (n = 155), and IRS-IV (n = 517). There were 224 PFS events in Euro-EWING99-R1 and 200 in the validation set (EICESS92 + IRS-IV), and 171 and 154 deaths in each dataset, respectively. The estimated treatment-by-sex interaction for PFS in Euro-EWING99-R1 (HR = 1.73, 95% CI = 1.00-3.00) was not replicated in the validation set (HR = 0.97, 95% CI = 0.55-1.72), without heterogeneity across trials (P = 0.62). In the pooled analysis, the treatment-by-sex interaction was not significant (HR = 1.31, 95% CI = 0.89-1.95, P = 0.17), without heterogeneity across age categories (P = 0.88) and trials (P = 0.36). Similar results were observed for OS. No significant treatment-by-sex interaction was observed for leucopenia/neutropenia (P = 0.45), infection (P = 0.64), or renal toxicity (P = 0.20). Our meta-analysis did not confirm the hypothesis of a treatment-by-sex interaction on efficacy or toxicity outcomes. © 2017 Wiley Periodicals, Inc.

Occupational Exposure to Chemotherapy of Pharmacy Personnel at a Single Centre

2015-01-01

Background: Cyclophosphamide is one of the most commonly used chemotherapy drugs worldwide. Data concerning environmental contamination and biological exposure of pharmacy personnel to this and other chemotherapy drugs are limited. Objectives: To determine whether pharmacy personnel involved in preparing and checking cyclophosphamide doses were more likely to have detectable levels of this drug in their urine than non-oncology pharmacy personnel with no known contact with the drug, and to compare the degree of surface contamination with cyclophosphamide, methotrexate, and ifosfamide in the oncology pharmacy of a tertiary care pediatric hospital, where chemotherapy doses were prepared, and the main (control) pharmacy in the same institution, where no chemotherapy was prepared. Methods: Biological exposure to cyclophosphamide was compared between pharmacy personnel who did and did not handle this drug by determining whether participants had detectable amounts of cyclophosphamide in their urine. Environmental exposure to chemotherapy drugs was assessed by using surface wipes to determine the degree of surface contamination with various chemotherapy agents in the oncology pharmacy and the main (control) pharmacy. Results: On initial testing, cyclophosphamide was detected in the urine of all pharmacy personnel (n = 7 oncology personnel, n = 5 control personnel). However, it was determined that all control personnel had been exposed to the oncology pharmacy on the day of testing. Repeat testing of these individuals revealed no positive samples among those not exposed to the oncology pharmacy on the day of repeat testing. The sole positive result on retesting of control personnel was for a participant who had been exposed to the oncology pharmacy on the retest day. Surface wipe testing revealed contamination of the oncology pharmacy with cyclophosphamide and methotrexate before and after cleaning, as well as contamination with ifosfamide after cleaning. The main (control) pharmacy showed no evidence of contamination with cyclophosphamide, methotrexate, or ifosfamide. Conclusions: The findings suggest that environmental contamination plays a role in biological exposure to cyclophosphamide. Measures to reduce environmental contamination from chemotherapy and biological exposure of pharmacy personnel when handling chemotherapy agents should be identified and implemented as a priority.

This study examined the degradation behavior of polycyclic musks (PMs) and antineoplastic drugs (ADs) and the absorbance spectra of effluent organic matter (EfOM) in municipal wastewater by ozone. Specific ozone doses used in the experiments ranged from 0 to 1mg O3/mg dissolved organic matter (DOC). The examined PMs included galaxolide, tonalide, celestolide, traseolide and phantolide. ADs included busulfan, chlorambucil, cyclophosphamide, dacarbazine, flutamide, ifosfamide, tamoxifen and methotrexate. Strong monotonic albeit nonlinear correlations were found to exist between relative changes of EfOM absorbance at 254 nm (i.e. ΔA254/A(0)254) and the degradation of the selected PMs and ADs. This result was interpreted based on the concept of the simultaneous oxidation of EfOM and, on the other hand, PMs and ADs. This interpretation showed that PMs were degraded primarily via OH radical attack, with tonalide and phantolide being less reactive compared with the other PMs. ADs such as cyclophosphamide, ifosfamide and busulfan were also determined to undergo oxidation by OH radicals. Comparison of the behavior of the radical probe para-chlorobenzoic acid and the examined ADs and PMs allowed evaluating corresponding reaction rate constants for reactions between these species and OH radicals.

To explore the clinical effect and toxicity of (cisplatin, etoposide, ifosfamide & dexamethasone) DECP combination chemotherapy in the treatment of relapsing and refractory multiple myeloma (MM) with extramedullary plasmacytomas. A total of 20 relapsed and refractory MM patients with extramedullary plasmacytomas treated with DECP regimen from May 2005 to May 2013 were analyzed retrospectively. DECP protocols included cisplatin 20 mg/m(2), Day 1-3; etoposide 100 mg/d,Day 1-3; ifosfamide 500 mg·m(-2)·d(-1), Day 1-4; dexamethasone 20 mg/d, Day 1-4. Efficacy was evaluated after 2 therapeutic cycles. After 2 therapeutic cycles, the objective response rate (ORR) was 55% (11/20). After 3 therapeutic cycles, the ORR was 7/12.Seven patients completed 4 cycles with an ORR of 4/7. Two patients had finished 6 cycles and continued to maintain partial remission. The most common adverse events included gastrointestinal reaction and myelosuppression. The median follow-up time was 30 (12-80) months. The median time of overall survival (OS) was 30 (9-121) months. The 1-year OS was 73%, 2-year OS 28% and 3-year OS 21%. The DECP chemotherapy is both effective and safe in the treatment of relapsed and refractory MM patients with extramedullary plasmacytomas.

Based on recent directed evolution of P450 2B1, six P450 2B11 mutants at three positions were created in an N-terminal modified construct termed P450 2B11dH and characterized for enzyme catalysis using five substrates. Mutant I209A demonstrated a 3.2-fold enhanced kcat/Km for 7-ethoxy-4-trifluoromethylcourmarin O-deethylation, largely due to a dramatic decrease in Km (0.72 vs. 18 μM). I209A also demonstrated enhanced selectivity for testosterone 16β-hydroxylation over 16α-hydroxylation. In contrast, V183L showed a 4-fold increased kcat for 7-benzyloxyresorufin debenzylation and a 4.7-fold increased kcat/Km for testosterone 16α-hydroxylation. V183L also displayed a 1.7-fold higher kcat/Km than P450 2B11dH with the anti-cancer prodrugs cyclophosphamide and ifosfamide, resulting from a ~4-fold decrease in Km. Introduction of the V183L mutation into full-length P450 2B11 did not enhance the kcat/Km. Overall, the re-engineered P450 2B11dH enzymes exhibited enhanced catalytic efficiency with several substrates including the anti-cancer prodrugs. PMID:17254539

To describe the pharmacokinetics of R- and S-Ifosfamide (IFF), and their respective 2 and 3 N-dechloroethylated (DCE) metabolites (R2-, R3-, S2, S3-DCE-IFF) in cancer patients. (R,S)-IFF was administered (1.5 g/m2) daily for 5 days in 13 cancer patients. Plasma and urine samples were collected and analyzed using an enantioselective GC-MS method. An average of 97 observations per patient were simultaneously fitted using a pharmacokinetic-metabolism (PK-MB) model. A population PK analysis was performed using an iterative 2-stage method (IT2S). Auto-induction of IFF metabolism was observed over the 5 day period. Increases were seen in IFF clearance (R: 4 vs. 7 L/h; S: 5 vs. 10 L/h), and in the formation of DCE (R: 7 vs. 9%; S: 14 vs. 19%) and active metabolites (4-OHM-IFF; R: 71 vs. 77%; S: 67 vs. 71%). A novel finding of this analysis was that the renal excretion of the DCE metabolites was also induced. This population PK-MB model for (R,S)-IFF may be useful in the optimization of patient care, and gives new insight into the metabolism of (R,S)-IFF.

High-dose melphalan (HDM) and autologous blood stem cell transplantation (ABSCT) is an effective treatment for transplantation-eligible patients with systemic light chain (AL) amyloidosis. Whereas most centers use granulocyte colony-stimulating factor (G-CSF) alone for mobilization of peripheral blood stem cells (PBSC), the application of mobilization chemotherapy might offer specific advantages. We retrospectively analyzed 110 patients with AL amyloidosis who underwent PBSC collection. Major eligibility criteria included age <70 years and cardiac insufficiency New York Heart Association ≤III°. Before mobilization, 67 patients (61%) had been pretreated with induction therapy, including 17 (15%) patients who had received melphalan. Chemo-mobilization was performed with either cyclophosphamide, doxorubicin, dexamethasone (CAD)/G-CSF (n = 78, 71%); ifosfamide/G-CSF (n = 14, 13%); or other regimens (n = 8, 7%). AL amyloidosis patients with predominant heart involvement and/or status post heart transplantation were mobilized with G-CSF only (n = 10, 9%). PBSC collection was successful in 101 patients (92%) at first attempt. The median number of CD34 + cells was 8.7 (range, 2.1 to 45.5) × 10 6 CD34 + /kg collected in a median of 1 leukapheresis (LP) session. Compared with G-CSF-only mobilization, a chemo-mobilization with CAD/G-CSF or ifosfamide/G-CSF had a positive impact on the number of collected CD34 + cell number/kg per LP (P <.001, multivariate). Melphalan-containing previous therapy and higher age had a significant negative impact on quantity of collected CD34 + cells. Median common toxicity criteria (CTC) grade of nonhematologic toxicity was II (range, 0 to IV). Life-threatening CTC grade IV adverse events were observed in 3 patients with no fatalities. Cardiovascular events were observed in 17 patients (22%) upon CAD/G-CSF mobilization (median CTC: grade 3; range, 1 to 4). Toxicity in patients undergoing ifosfamide/G-CSF mobilization was higher than in with those who received G-CSF-only mobilization. HDM and ABSCT were performed in 100 patients. Compared with >6.5 × 10 6 transplanted CD34 + cells/kg, an ABSCT with <3 × 10 6 CD34 + cells/kg was associated with a longer duration to leukocyte reconstitution >1 × 10 9 /L and a reduced platelet count <150 × 10 9 /L 1 year after ASCT. Our results show that CAD chemotherapy is very effective in PBSC mobilization and has a tolerable toxicity profile in AL amyloidosis patients. A further toxicity reduction by omission of doxorubicin might be considered. Because of advanced nonhematologic toxicity, ifosfamide administration cannot be recommended. However, G-CSF mobilization alone is also safe and effective. Considering the hematopoietic reconstitution and long-term stem cell function, our results provide a rationale to collect and transplant as many as >6.5 × 10 6 CD34 + cells/kg, if feasible with reasonable effort.

Ewing's sarcoma is usually diagnosed in adolescents and young adults, peak of incidence is around 15 years of age. Primary localization is mostly in the skeleton of long bones and chest wall. Primary extraosseous involvement rarely occurs, incidence increases with age. We present a case report of a 57-year-old patient with locally advanced tumors of the cervix, clinical stage IIB. Due to histological and molecular genetic examination revealing EWS -ERG fusion gene, Ewing's sarcoma was diagnosed. CT revealed pathological pelvic lymphadenopathy and multiple pulmonary bilateral methastases, scintigraphy did not prove any affection of skeleton. The patient underwent a two-stage intensive chemotherapy regimens VIDE (vincristine, ifosfamide, doxorubicin, etoposide) and VAI (vincristine, actinomycin D, ifosfamide). During the second phase, concomitant radiotherapy of pelvis was aplied. According to PET/CT, complete remission was achieved. Whole-lung irradiation was applied in consolidation of the result. Primary Ewing's sarcoma of the cervix is an extremely rare disease. To our knowledge, only 12 cases was presented until this time. The average age at time of dia-gnosis was 35 years. Unlike the previous reports, we initially diagnosed distant metastases. The treatment was led according to the protocol Ewing 2008 designed for primary skeletal Ewing's sarcoma. Currently, 18 months after the therapy, the patient is without signs of disease. However, long-term follow-up is necessary.

Bladder carcinoma (BC), due its high morbidity and relapsing course, generates significant economic and health care costs. Accordingly, review the environmental nonoccupational risk factors (RF), more or less evidence-based, in the etiology and pathogenesis of BC, because the involvement of urologists is essential for prevention. Review of the peer-reviewed literature (1987-2012) on nonoccupational environmental RF associated with BC retrieved from Medline, Embase and Science Citation Index. The search profiles have been "Risk factors/Epidemiology/Tobacco-smoking/Diet-nutrition-water-liquids/Radiation/Infectious/Farmacological drugs" and "Bladder cancer". Smoking was associated with 50% of BC in both sexes. Smokers have a 2-5 times higher risk than nonsmokers, directly proportional to the amount and duration of addiction. Drinking water contaminated with arsenic and chromium chlorination byproducts increases the risk of BC. High consumption of red meat and saturated fat may increase the risk, while high intake of fruits and vegetables decreases it. Patients treated with cyclophosphamide, ifosfamide and ionizing radiation have an increased risk of BC. Frequent and prolonged use of hair dyes and Schistosoma haematobium infestation increases the risk of BC. The reduction or the cessation of smoking decrease BC. The contaminant-free water consumption with the increase of vegetal foods favour BC prevention. Cancer survivors treated with cyclophosphamide, ifosfamide and radiation therapy should be monitored for early diagnosis of BC. Copyright © 2013 AEU. Published by Elsevier Espana.

Ifosfamide was administered to 21 patients with recurrent or disseminated lung cancer at a dose of 4.0 gm/M2 iv every 3 weeks. The response rate was 33% with an additional 14% showing no response or stable disease. At a dose of 1.2 gm/M2 daily for 5 days every 4 weeks, 57% of 14 patients responded with 35% showing no response or stable disease. The majority of the patients (28) had epidermoid carcinoma. Two (7%) had complete response with 9 (32%) showing partial responses. Other responses included 1/2 oat cell carcinomas and 3/6 large cell undifferentiated carcinomas. Toxicity was equal in both regimens for nausea, vomiting, increased serum LDH and neutropenia but the 5 day program had significantly less hemorrhagic cystitis. Survival was greatly influenced by response. There was no statistical difference in overall length of response between responders and the non responding/stable disease patients. But these two groups had a very significant survival advantage when compared to those patients with increasing disease. Similarly, there was a significant improvement in response duration for the low dosage regimen. Therefore, the low dose 5 day regimen is recommended because of its response rate, it has less hemorrhagic cystitis and it has better patient acceptance in that it can be given as an outpatient and does not require a Foley catheter.

A total of 15 patients with relapsed or resistant Hodgkin's disease were treated with a combination of etoposide (VP16), ifosfamide, mitozantrone and dexamethasone (VIM-D). The regime was well tolerated, the only major toxicity being myelosuppression. Complete remissions (CRs) were obtained in 4 patients and were maintained for 2, 4, 10 and 14 months. 10 subjects subsequently received an autologous bone marrow transplant with high-dose chemotherapy (ABMT). Previous exposure to VIM-D did not appear to predict for or prejudice the response to subsequent ABMT.

Cytostatic drug residues in the aqueous environment are of concern due to their possible adverse effects on non-target organisms. Here we report the occurrence and removal efficiency of cyclophosphamide (CP) and ifosfamide (IF) by biological and abiotic treatments including advanced oxidation processes (AOPs). Cyclophosphamide was detected in hospital wastewaters (14-22,000 ng L(-1)), wastewater treatment plant influents (19-27 ng L(-1)) and effluent (17 ng L(-1)), whereas IF was detected only in hospital wastewaters (48-6800 ng L(-1)). The highest removal efficiency during biological treatment (attached growth biomass in a flow through bioreactor) was 59 ± 15% and 35 ± 9.3% for CP and IF, respectively. Also reported are the removal efficiencies of both compounds from wastewater using hydrodynamic cavitation (HC), ozonation (O3) and/or UV, either individually or in combination with hydrogen peroxide (H2O2). Hydrodynamic cavitation did not remove CP and IF to any significant degree. The highest removal efficiencies: 99 ± 0.71% for CP and 94 ± 2.4% for IF, were achieved using UV/O3/H2O2 at 5 g L(-1) for 120 min. When combined with biological treatment, removal efficiencies were >99% for both compounds. This is the first report of combined biological and AOP treatment of CP and IF from wastewater with a removal efficiency >99%. Copyright © 2015 Elsevier B.V. All rights reserved.

A phase II trial was performed to evaluate the efficacy and toxicity of a combination of cisplatin (CDDP) and ifosfamide (IFX) as neoadjuvant chemotherapy in advanced cervical carcinoma (ACC). Between August 1991 and September 1993, 57 untreated patients with stages IIB to IVA were entered into this study. Median age was 44 years (range, 25 to 74 years). The distribution by stages (International Federation of Gynecology and Obstetrics) was as follows: IIB, 31 patients; IIIB, 21 patients; and IVA, 5 patients. Therapy consisted of IFX 2000 mg/m(2) 1-h i.v. infusion days 1 to 3; mesna 400 mg/m(2) i.v. bolus at hours 0 and 4, and 800 mg p.o. at hour 8; and CDDP 100 mg/m(2) on day 3. Cycles were repeated every 28 days for a total of three courses. Both staging and response assessment were performed by a multidisciplinary team. An objective response was observed in 30 of 56 patients (54%; 95% confidence interval, 41 to 67%). Four patients (7%) had a complete response (CR) and 26(46%) had a partial response (PR). Patients with CR or operable PR underwent surgery, otherwise received definitive radiotherapy. Toxicity was mild to moderate. There were no toxicity related deaths. These results indicate that IFX/CDDP is an active combination for ACC with mild toxicity. The results of phase III studies that evaluate the real impact of neoadjuvant chemotherapy are awaited.

There is no proven benefit of adjuvant treatment of uterine sarcoma (US). SARCGYN phase III study compared adjuvant polychemotherapy followed by pelvic radiotherapy (RT) (arm A) versus RT alone (arm B) conducted to detect an increase ≥ 20% of 3-year PFS. Patients with FIGO stage ≤ III US, physiological age ≤ 65 years; chemotherapy: four cycles of doxorubicin 50 mg/m² d1, ifosfamide 3 g/m²/day d1-2, cisplatin 75 mg/m² d3, (API) + G-CSF q 3 weeks. Study was stopped because of lack of recruitment. Eighty-one patients were included: 39 in arm A and 42 in arm B; 52 stage I, 16 stage II, 13 stage III; 53 leiomyosarcomas, 9 undifferenciated sarcomas, 19 carcinosarcomas. Gr 3-4 toxicity during API (/37 patients): thrombopenia (76%), febrile neutropenia (22%) with two toxic deaths; renal gr 3 (1 patient). After a median follow-up of 4.3 years, 41/81 patients recurred, 15 in arm A, 26 in arm B. The 3 years DFS is 55% in arm A, 41% in arm B (P = 0.048). The 3-year overall survival (OS) is 81% in arm A and 69% in arm B (P = 0.41). API adjuvant CT statistically increases the 3 year-DFS of patients with US.

Context Bladder carcinoma (BC), due its high morbidity and relapsing course, generates significant economic and health care costs. Accordingly, we reviewed the environmental nonoccupational risk factors (RF), more or less evidence-based, in the etiology and pathogenesis of BC, because the involvement of urologists is essential for prevention. Acquisition of evidence Review of the peer-reviewed literature (1987–2012) on nonoccupational environmental RF associated with BC retrieved from Medline, Embase and Science Citation Index. The search profiles have been “Risk factors/Epidemiology/Tobacco-smoking/Diet-nutrition-water-liquids/Radiation/Infectious/Farmacological drugs” and “Bladder cancer”. Synthesis of evidence Smoking was associated with 50% of BC in both sexes. Smokers have a 2–5 times higher risk than nonsmokers, directly proportional to the amount and duration of addiction. Drinking water contaminated with arsenic and chromium chlorination byproducts increases the risk of BC. High consumption of red meat and saturated fat may increase the risk, while high intake of fruits and vegetables decreases it. Patients treated with cyclophosphamide, ifosfamide and ionizing radiation have an increased risk of BC. Frequent and prolonged use of hair dyes and Schistosoma haematobium infestation increases the risk of BC. Conclusions The reduction or the cessation of smoking decrease BC. The contaminant-free water consumption with the increase of vegetal foods favors BC prevention. Cancer survivors treated with cyclophosphamide, ifosfamide and radiation therapy should be monitored for early diagnosis of BC. PMID:23618510

The aim of this study was to evaluate prognostic factors, survival rate and the efficacy of the treatment modalities used in patients with extraskeletal Ewing's sarcoma. Data of patients with extraskeletal Ewing's sarcoma followed up at our center between 1997 and 2010 were retrospectively analyzed. The median age of 27 patients was 24 years (range, 16-54 years). The median follow-up was 31.8 months (range, 6-144 months). Tumor size was between 1.5 and 14 cm (median: 8 cm). Eighty-five percent of patients had localized disease at presentation and 15% had metastatic disease. Local therapy was surgery alone in 16% of patients, surgery combined with radiotherapy in 42% and radiotherapy alone in 27%. All patients were treated with vincristine, doxorubicin, cyclophosphamide and actinomycin-D, alternating with ifosfamide and etoposide every 3 weeks. In patients with localized disease at presentation, the 5-year event-free survival and overall survival were 59.7 and 64.5%, respectively. At univariate analysis, patients with tumor size ≥ 8 cm, high serum lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy and positive surgical margin had significantly worse event-free survival. The significant predictors of worse overall survival at univariate analysis were tumor size 8 ≥ cm, high lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy, radiotherapy only as local treatment and positive surgical margin. Prognostic factors were similar to primary osseous Ewing's sarcomas. Adequate surgical resection, aggressive chemotherapy (vincristine, doxorubicin, cyclophosphamide and actinomycin-D alternating with ifosfamide and etoposide) and radiotherapy if indicated are the recommended therapy for patients with extraskeletal Ewing's sarcoma.

Background: Refractory or relapsed Hodgkin's disease (HD) occurs in 10-50% of patients. The treatment of choice for these patients is high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT). Response to salvage chemotherapy (SCT) partial remission (PR) is necessary before HDCT with ASCT. However, its applicability is restricted mostly to patients responding to salvage chemotherapy. Optimal salvage regimen for these patients is unclear. In this study, our aim was to compare the efficacy profiles of ifosfamide, carboplatin, and etoposide (ICE) and etoposide-steroid-cytarabine-cisplatin (ESHAP) (cytosine arabinoside, cisplatin, and dexamethasone) regimens in the salvage treatment of relapsed or refractory HD. Materials and Methods: In this retrospective analysis, 114 patients with primary refractory or relapsed HD who received ICE or ESHAP salvage regimen were included. Results: Of 114 patients, 47 (41.2%) were females and the median age was 31.5 years. Response could be evaluated in 114 patients. Of 114 patients, 38 (33%) achieved complete remission (CR) and 21 (18.4%) achieved PR, leading to an overall response rate (ORR: CR + PR) of 51.4%. In the evaluable ICE group (n = 41), rates of CR, PR, and ORR were 21.9%, 17.1%, and 39% and in the ESHAP group (n = 73), rates of CR, PR, and ORR were 39.7%, 19.2%, and 58.9% (for ORR, P = 0.04), respectively. Conclusion: In patients with relapsed or refractory HD, treatment with ESHAP seems to have higher rates of response than ICE regimen does. PMID:28401077

The use of neoadjuvant and adjuvant chemotherapy in soft tissue sarcomas is controversial. This is a report of long-term (≥5 years) follow-up in patients with high-grade, high-risk soft tissue sarcomas treated with neoadjuvant chemotherapy, preoperative radiotherapy (RT), and adjuvant chemotherapy. Patients with high-grade soft tissue sarcoma≥8 cm in diameter of the extremities and body wall received 3 cycles of neoadjuvant chemotherapy (mesna, doxorubicin, ifosfamide, and dacarbazine) and preoperative RT (44 grays administered in split courses), and 3 cycles of postoperative chemotherapy (mesna, doxorubicin, ifosfamide, and dacarbazine). Sixty-four of 66 patients were analyzed. After chemotherapy and RT, 61 patients had surgery; 58 had R0 resections (5 amputations), and 3 had R1 resections. Ninety-seven percent experienced grade 3 or higher toxicity, including 3 deaths. These toxicities were short term. With a median follow-up of 7.7 years in surviving patients, the 5-year rates of locoregional failure (including amputation), and distant metastasis were 22.2% (95% confidence interval [CI], 11.8-32.6) and 28.1% (95% CI, 17.0-39.2). The most common site of metastasis was lung. Estimated 5-year rates of disease-free survival, distant disease-free survival, and overall survival were 56.1% (95% CI, 43.9-68.3), 64.1% (95% CI, 52.3-75.8), and 71.2% (95% CI, 60.0-82.5), respectively. Although the toxicity was significant, it was limited in its course and for the most part resolved by 1 year. The long-term outcome was better than might be expected in such high-risk tumors.

We evaluated the efficacy and toxicity of the novel combination of ifosfamide (IFX) and vinorelbine (VNB) as first-line chemotherapy in patients with stage IIIB and IV non-small cell lung cancer (NSCLC). Between March 1993 and November 1994, 44 patients (17 stage IIIB; 27 stage IV) received a regimen consisting of IFX, 2 g/m2 in a 1-h infusion, days 1-3; mesna, 400 mg/m2 in an i.v. bolus at hours 0 and 4 and 800 mg orally at hour 8, days 1-3; and VNB, 35 mg/ m2 in a 20-min infusion, days 1 and 15. During the first course only, a half dose of VNB (17.5 mg/m2) was administered on days 8 and 22. Courses were repeated every 28 days. Forty patients were fully evaluable for response, and 44 were assessable for toxicity. Objective regression was recorded in 13 of 40 patients (33%). No patient achieved a complete response. Thirteen patients presented a partial response (33%); 17 (42%) had no change; and progressive disease was observed in 10 (25%). The median duration of response was 10 months, and the median time to treatment failure for the whole group was 4 months. Median survival was 11 months. The dose-limiting toxic effect was myelosuppression. Leukopenia occurred in 25 patients (57%) and was grade 3 or 4 in 8 patients (18%). Twelve patients (27%) developed peripheral neurotoxicity, while five had mild IFX-induced CNS toxicity. Phlebitis was observed in 15 of 30 patients (50%) who did not have central implantable venous systems. The IFX-VNB combination exhibited an activity against NSCLC that was among the highest reported for non-cisplatin-containing regimens, with a toxicity profile that was easily managed.

To evaluate the efficacy and toxicity of the combination of ifosfamide (IFX) and vinorelbine (VNB) as first-line chemotherapy in metastatic breast cancer (MBC). Between August 1993 and August 1995, 45 patients with untreated MBC received a regimen that consisted of IFX 2 g/m2 by 1-hour intravenous (i.v.) infusion on days 1 to 3, mesna 400 mg/m2 by i.v. bolus at hours 0 and 4 and 800 mg/m2 orally at hour 8 on days 1 to 3, and VNB 35 mg/m2 by 20-minute i.v. infusion on days 1 and 15. Courses were repeated every 28 days. During the first course only, half-dose VNB (17.5 mg/m2) was administered on days 8 and 22. The median age was 53 years and 30 patients (67%) were postmenopausal. Dominant sites of disease were soft tissue in nine patients, bone in seven, and visceral in 29. Objective responses (ORs) were recorded in 25 of 43 assessable patients (58%; 95% confidence interval, 43% to 73%). Complete remissions (CRs) occurred in six patients (14%) and partial remissions (PRs) in 19 (44%). No change (NC) was recorded in 10 patients (23%) and progressive disease (PD) in eight patients (19%). The median time to treatment failure was 12 months and the median survival duration 19 months. Myelosuppression was the limiting toxicity, mainly leukopenia in 32 patients (74%). In contrast, anemia and thrombocytopenia were mild. Other significant toxicities included peripheral neuropathy in nine patients (21%), constipation in 15 (35%), and myalgias in 11 (26%). IFX/VNB is an active combination against MBC with moderate toxicity and deserves further evaluation.

A phase II trial was performed to evaluate the efficacy and toxicity of a combination of ifosfamide (IFX) and mitoxantrone (MXN) as first-line chemotherapy for metastatic breast carcinoma. Between January 1990 and August 1991, 48 patients with metastatic breast cancer were entered onto the study. Therapy consisted of IFX 2 g/m2 given as a 1-hour intravenous (IV) infusion on days 1 to 3; mesna 400 mg/m2 as an IV bolus immediately before and 4 hours after IFX administration and 2,000 mg orally 8 hours after IFX administration on days 1 to 3; and MXN 12 mg/m2 as an i.v. bolus on day 3. Cycles were repeated every 21 days until progressive disease (PD) or severe toxicity developed. One patient was considered not assessable for response. Objective regression (OR) was observed in 28 of 47 patients (60%; 95% confidence interval, 46% to 74%). Six patients (13%) had a complete response (CR) and 22 (47%) had a partial response (PR). The median time to treatment failure for the whole group was 9 months (range, 1 to 28); median survival was 19 months (range, 2 to 28). There were no treatment-related deaths. The limiting toxicity was myelosuppression. Leukopenia occurred in 37 patients (77%) and was grade 3 or 4 in 19 patients (40%). Nausea and vomiting were observed in 38 patients (80%), mucositis in 16 patients (33%), and grade 2 hematuria in two patients (4%). Eight patients (16%) developed mild neurotoxicity. The combination of IFX plus MXN is an active regimen against metastatic breast cancer with moderate toxicity that deserves further evaluation.

Because of the relative lack of overlapping toxicity, carboplatin (PPL) and cisplatin (CDDP) can be easily combined for treatment of ovarian cancer to increase total platinum dose intensity. Ifosfamide (IFO), one of the most effective single agents in ovarian cancer, has a low hematological toxicity when administered in continuous infusion. From January 1991 to December 1993, 34 patients with advanced ovarian cancer, previously untreated with chemo- or radiotherapy, were enrolled in a phase I-II study with the aim of determining the maximum tolerated dose (MTD) of CDDP (on day 8 of a 28-day cycle) in combination with PPL (300 mg/m2 on day 1) and IFO (4,000 mg/m2/24 h by continuous infusion on day 1). The initial dose level of CDDP was 40 mg/m2, which was continuously increased by 10 mg/m2 up to the MTD defined as one dose level below that inducing dose-limiting toxicity (DLT) in at least two-thirds of treated patients; no dose escalation was allowed in the same patient. Grade 3-4 leukopenia and thrombocytopenia were observed in 54 and 49% of patients, respectively. The DLT was reached at 70 mg/m2 and therefore the dose recommended for the phase II study was 60 mg/m2. Complete (CR) plus partial response was observed in 88% of patients with a 21% pathological CR. With a minimum follow-up of 32 months (median 40 months), median progression-free survival and overall survival were 21 and 39 months, respectively. In conclusion, the combination of CDDP, PPL, and IFO provides an effective regimen for ovarian cancer with an acceptable toxicity profile.

The purpose of this study was to evaluate the toxicity and response efficacy of fixed-dose oral ifosfamide (OI)-mesna (M) in advanced, non-small-cell lung cancer (NSCLC). OI was given in four different fractionated-dose treatment schedules with a total dose per cycle of either 3.0 g/m2, 6.0 g/m2, 7.5 g/m2 or 10 g/m2 (equivalent to a daily dose of either 750 mg, 1000 mg or 1250 mg.) M was given p.o. by drinking ampules. In the 64 patients (pts) included, a total of 305 treatment cycles were administered with no evidence of severe neurotoxicity. Twenty-two pts (37%) developed mild to moderate CNS toxicity. Neither myelosuppression, alopecia, gastrointestinal toxicity nor urotoxicity were clinical problems. On schedule 2 (6 g/m2), 3 of 14 evaluable pts (21%) had partial remissions (PR), and on schedule 3 (7.5 g/m2) 4 pts (25%) showed PRs. The median duration of response was 9 months (mts) for pts on schedule 2, and 8 mts for pts on schedule 3. We conclude that OIM can easily be tolerated in the same dose usually given intravenously (7.5 g/m2/mts), when patients at high risk for developing CNS toxicity have been previously excluded from therapy. In order to reduce CNS toxicity, it is suggested that the total dose per cycle should not exceed 7.5 g/m2 (1000 mg daily) within a fractionated-dose, 14-day treatment schedule. We further conclude that the tumor response efficacy of OIM in NSCLC is comparable to the one achieved by intravenously-administered IM, whereby the total monthly OI dose should not be less than 6.0 g/m2 (750 mg daily).

Thirty-five consecutive patients with small cell bronchogenic carcinoma (SCBC) received chemoimmunotherapy with VP-16-213, Ifosfamide, vincristine, Adriamycin, and Corynebacterium parvum. Of 33 evaluable patients, 26 (79%) responded with complete (55%) or partial (24%) remissions. Complete remissions were more common among patients with limited disease (11/14 patients, 79%) compared with those with extensive disease (7/19 patients, 37%) and among patients (11/14 patients, 79%) compared with those with extensive disease (7/19 patients, 37%) and among patients who were ambulatory prior to therapy (16/25 patients, 64%) compared with those who were nonambulatory (2/8 patients, 25%). Myelosuppression consisted primarily of neutropenia. Eight percent of themore » treatment courses in 29% of the patients were associated with hematuria and/or documented episodes of infection during neutropenia. There were three deaths possibly related to treatment, in two of which there was no evidence of disease at post-mortem examination. Six patients relapsed in the central nervous system (CNS). In four instances, CNS relapse was the only site of tumor progression. Central nervous system relapse was more common among evaluable patients who did not receive prophylactic brain irradiation (5/17 patients, 29%, vs. 1/15 patients, 7%; P . 0.23). The median survival duration for all patients was 63 weeks, being slightly longer for patients with limited disease than for those with extensive disease (70.9 weeks vs. 56 weeks; P . 0.18). This was also true for patients who achieved complete rather than partial remissions (71 weeks vs. 50 weeks; P . 0.09). Patients receiving prophylactic brain irradiation experienced longer survival (100.8 weeks vs. 48 weeks; P . 0.01).« less

The therapeutic outcomes of patients with advanced vulvar cancer are poor. Multi-modality treatments including concurrent chemoradiation or different regimens of neoadjuvant chemotherapy (NACT), and surgery have been explored to reduce the extent of surgery and morbidity. The present single-institution trial aimed to evaluate the efficacy and toxicity of paclitaxel and cisplatin in locally advanced vulvar cancer. From 2002 to 2009, 10 patients with stage III-IV locally advanced squamous cell carcinoma of the vulva were prospectively treated with 3 courses of paclitaxel-ifosfamide-cisplatin or paclitaxel-cisplatin. Nine of them subsequently underwent radical local excision or radical partial vulvectomy and bilateral inguino-femoral lymphadenectomy. The clinical response rate of all enrolled patients was 80%, whereas the pathological responses included 1 case with complete remission, 2 with persistent carcinoma in situ, and 6 invasive cancer cases with tumor shrinkage of more than 50%. Four patients had positive nodes. Forty percent of patients experienced grade 3-4 bone marrow toxicity, which was successfully managed with granulocyte-colony stimulating factor, even in cases of elderly patients. Median progression-free survival after surgery was 14 months (range, 5 to 44 months). Six of the 7 recurrent cases were local, and 3 of them were treated with salvage surgery while the other 3 received radiation with or without chemotherapy. After a median follow-up period of 40 months (range, 5 to 112 months), 55.5% of patients remained alive with no evidence of disease, including 2 long-term survivors after recurrence at 5 and 9 years. Based on the high response rate and manageable toxicity, NACT with paclitaxel and cisplatin with or without ifosfamide followed by surgery could be considered as a therapeutic option for locally advanced vulvar cancer.

Sequential chemotherapy with doxorubicin and gemcitabine (AG) followed by ifosfamide, paclitaxel, and cisplatin (ITP) was previously demonstrated to be well tolerated in patients with advanced transitional cell carcinoma (TCC). This study sought to evaluate the efficacy and to additionally define toxicity. Sixty patients with advanced TCC received AG every 2 weeks for five or six cycles followed by ITP every 21 days for four cycles. Granulocyte colony-stimulating factor was given between cycles. Myelosuppression was seen with 68% of patients who experienced grades 3 to 4 neutropenia and with 25% who experienced febrile neutropenia. Grade 3 or greater nonhematologic toxicities were infrequent. Forty (73%) of 55 evaluable patients (95% CI, 59% to 84%) demonstrated a major response (complete, n = 19; partial, n = 21) and had a median response duration of 11.3 months (range, 1.7 to >or= 105.6 months). Twenty-seven (79%) of 34 patients with locally advanced disease (ie, T4, N0, M0) or with regional lymph node involvement (ie, T3-4, N1, M0) and 10 (56%) of 18 patients with distant metastases achieved a major response. The median progression-free survival was 12.1 months (95% CI, 9.0 to 14.8 months), and the median overall survival was 16.4 months (95% CI, 14.0 to 22.5 months). At a median follow-up of 76.4 months, seven (11.7%) patients remain alive, and all were disease free. AG plus ITP is an active regimen in previously untreated patients with advanced TCC; however, it is associated with toxicity and does not clearly offer a benefit compared with other nonsequential, cisplatin-based regimens.

Objective: To investigate the possible protective effect of a single dose of ketamine and the synergistic effect between ketamine and 2-mercaptoethane sulfonate (mesna) against ifosfamide-induced hemorrhagic cystitis. Materials and Methods: 35 adult female wistar rats were divided into five groups and pretreated with ketamine at 10 mg/kg and/or mesna 400 mg/kg 30 minutes before intraperitoneal injection of IFS (400 mg/kg) or with saline (control group). Hemorrhagic cystitis was evaluated 24 hours after IFS injection according to bladder wet weight (BWW), and microscopic changes, i.e. edema, hemorrhage, cellular infiltration, and urothelial desquamation. The markers of oxidative damage including nitric oxide (NO) and malondialdehyde (MDA) levels and the expressions of tumor necrosis factor alpha (TNF-α), interleukin 1-beta (IL-1β), inducible nitric oxide synthase (i-NOS) and endothelial nitric oxide synthase (e-NOS) were also assayed in the bladder tissues. Results: Pretreatment with ketamine alone or ketamine in combination with mesna reduced the IFS-induced increase of BWW (58,47% and 63,33%, respectively, P < 0.05). IFS- induced microscopic alterations were also prevented by ketamine with or without mesna (P < 0.05). In addition, also statistically insignificant, the bladder tissue expressions of IL-1β were lower in ketamine and/or mesna-receiving groups (P > 0,05). The parameters of oxidative stress, the NO and the MDA contents of the bladder tissues of the study groups were not different. Conclusion: The results of the present study suggest that a single dose of ketamine pretreatment attenuates experimental IFS-induced bladder damage. It is therefore necessary to investigate ketamine locally and systematically with various dosing schedulesin order to reduce the bladder damage secondary to oxazaphosphorine-alkylating agents and these results may widen the spectrum of ketamine.

The aims of the study were to quantify levels of dermal and inhalation exposure to antineoplastic drugs in an industrial laundry service in the Netherlands and to test the removal efficiency of the washing procedure for removal of antineoplastic drugs. During four workdays dermal and inhalation exposure to eight frequently used antineoplastic drugs (cyclophosphamide, ifosfamide, methotrexate, 5-fluorouracil, etoposide, cytarabine, gemcitabine and chlorambucil) were measured for all job titles involved in handling unwashed laundry. To test the removal efficiency of the washing procedure, 10 x 10 cm sections were excised before and after the washing procedure. These sections were taken from 15 bed sheets that were collected in hospitals of patients who were treated with one of the selected antineoplastic drugs. During none of the four measurement days, detectable levels of any of the eight antineoplastic drugs (cyclophosphamide, ifosfamide, methotrexate, 5-fluorouracil, etoposide, cytarabine, gemcitabine, or chlorambucil) were found on workers' skin of hands or in any of the air samples. Only four out of the 15 bed sheets from patients that were treated with antineoplastic drugs appeared to be contaminated with detectable levels of antineoplastic drugs before the washing procedure (range 13.0-3,060 ng/100 cm(2)). After the pre-washing and after the complete washing procedure, no detectable levels of any of the eight antineoplastic drugs were found anymore in the selected bed sheets. The implementation of guidelines for working with antineoplastic drugs seems to be successful in reducing exposure to antineoplastic drugs of workers in this laundry facility to an acceptable, non-detectable level and to remove antineoplastic drug contamination from bed linen.

The central nervous system toxicity of ifosfamide (IFF), a chiral antineoplastic agent, is thought to be dependent on its N-dechloroethylation by hepatic cytochrome P-450 (CYP) enzymes. The purpose of this study was to identify the human CYPs responsible for IFF-N-dechloroethylation and their corresponding regio- and enantioselectivities. IFF exists in two enantiomeric forms, (R) - and (S)-IFF, which can be dechloroethylated at either the N2 or N3 positions, producing the corresponding (R,S)-2-dechloroethyl-IFF [(R, S)-2-DCE-IFF] and (R,S)-3-dechloroethyl-IFF [(R,S)-3-DCE-IFF]. The results of the present study suggest that the production of (R)-2-DCE-IFF and (S)-3-DCE-IFF from (R)-IFF is catalyzed by different CYPs as is the production of (S)-2-DCE-IFF and (R)-3-DCE-IFF from (S)-IFF. In vitro studies with a bank of human liver microsomes revealed that the sample-to-sample variation in the production of (S)-3-DCE-IFF from (R)-IFF and (S)-2-DCE-IFF from (S)-IFF was highly correlated with the levels of (S)-mephenytoin N-demethylation (CYP2B6), whereas (R)-2-DCE-IFF production from (R)-IFF and (R)-3-DCE-IFF production from (S)-IFF were both correlated with the activity of testosterone 6beta-hydroxylation (CYP3A4/5). Experiments with cDNA-expressed P-450 and antibody and chemical inhibition studies supported the conclusion that the formation of (S)-3-DCE-IFF and (S)-2-DCE-IFF is catalyzed primarily by CYP2B6, whereas (R)-2-DCE-IFF and (R)-3-DCE-IFF are primarily the result of CYP3A4/5 activity.

Aggressive chemotherapy protocols for non-metastatic limb osteosarcoma have improved histological response without affecting prognosis. This study evaluated the toxicity and outcome of a dose-intensive, high-dose 3- to 5-drug pilot protocol, SCOS 89. The cohort included 26 patients (14 male; ages 6.5-22 years) with non-metastatic limb osteosarcoma treated at a tertiary pediatric medical center between 1989 and 2013. Preoperatively, patients received two courses of once-weekly pulses of high-dose methotrexate (12-30 g/m(2)) for 2 weeks; doxorubicin (90 mg/m(2)) with dexrazoxane, combined with cisplatin (200 mg/m(2)), was added in week 3. Following methotrexate, 760 mg/m(2) of folinic acid was administered. Postoperative chemotherapy was continued to a total of 14 courses of methotrexate, doxorubicin (up to a total dose of 360 mg/m(2)), and cisplatin (up to a total dose of 560 mg/m(2)). If toxicity occurred or <90 % tumor necrosis, ifosfamide (12 g/m(2)) plus etoposide (500 mg/m(2)) was substituted for doxorubicin, cisplatin, or methotrexate. Toxicity and death rates were calculated. All patients underwent definitive limb salvage surgery. Six patients died of infection, recurrent disease, or secondary malignancy. Median follow-up was 100 months (range 2-290). Event-free and overall survival rates, respectively, were 88 and 96 % at 2 years, 80 and 87.6 % at 5 years, 80 and 78 % at 10 years. Eleven patients required ifosfamide/etoposide substitution. One patient had a transient decreased left ventricular ejection fraction. Two patients developed acute nephrotoxicity during therapy, but no neurotoxicity. Seven patients had hearing impairment. The SCOS 89 yields a high event-free survival rate with reduced nephro-/neuro-/cardiotoxicity in patients with non-metastatic limb osteosarcoma.

One hundred and seven patients (61 with diffuse large B-cell non-Hodgkin's lymphomas and 46 with Hodgkin's disease) in relapse or following of primary therapy received ifosfamide 3 g/m2 i.v. daily for 3 days in combination with epirubicin 50 mg/m2 i.v. day 1 and etoposide 200 mg/m2 i.v. days 1-3. Of the 46 patients with Hodgkin's disease (28 male, 18 female, and a median age of 28 years) 85% of patients had a response to treatment, with 17 achieving complete remission and 11 good partial remission. Twenty-eight proceeded to autologous bone marrow or peripheral blood stem cell transplantation. Twenty-three patients remain alive in continuous remission with a follow-up of 12-61 months. The median overall survival time for all patients in this group is 36 months. Haematological toxicity, particularly WHO Grade IV neutropenia, occurred in all patients but improved over the three courses of treatment. There was no major non-haematological toxicity. Further trials of this regimen in this clinical situation are indicated. The patients with non-Hodgkin's lymphomas in this study had diffuse large B-cell lymphomas and had only received first-line treatment. Twenty had primarily refractory disease, 15 had only achieved partial remissions (PR), and 26 had developed relapse following primary treatment. The overall response rate was 43%; it was 60% for those who had achieved initial PR, 58% for those in relapse after an initial CR or very good PR following initial therapy, but only 10% for those with primarily refractory disease. Tolerance to the regimen was similar to that observed in treatment of the patients with Hodgkin's disease and many were able to undergo stem cell collection, following mobilization with this regimen. The 2-year overall survival result was 22% for patients with some response to first-line treatment but 0% for primary refractory patients.

Ifosfamide (IFO) is considered an essential drug for the treatment of pediatric, adolescent and young adult patients with solid tumors. Hemorrhagic cystitis (HC) is one of the dose-limiting toxicity of IFO. However, there are insufficient evidence for risk factor and supportive care of IFO-induced HC. In this retrospective study, patients (<30-year-old) with malignant solid tumors who had been treated with IFO-based chemotherapy, were categorized according to the presence or absence of HC, and were analyzed possible risk factors for IFO-induced HC. In our institution, continuous hydration to increase urine output and intravenous 2-mercaptethane sulfonate (mesna) are used for prophylaxis of IFO-induced HC. Increased hydration and dosage of mesna are administered to patients who develop IFO-induced HC; they also receive 24-h continuous infusion of mesna in subsequent treatment cycles. Nine treatment regimens were used in the 70 study patients. The range of daily IFO dosage was 1.2-3.0 g/m(2). HC occurred in 14/425 IFO-based chemotherapy cycles (3.3%). The daily IFO dosages (mean ± SD) in patients with or without HC were 2.23 ± 0.58 g/m(2) and 1.85 ± 0.50 g/m(2), respectively (P = 0.006). Only one of the nine patients who developed IFO-induced HC had experienced this complication in a subsequent cycle of treatment. The incidence of IFO-induced HC may be associated with the dosage of IFO. When administering IFO higher than 2.0 g/m(2)/day, the volume of hydration, dosage of mesna and duration of mesna infusion should be increased to prevent HC. © The Author 2016.

A phase II trial was performed to assess the efficacy and toxicity of a combination of ifosfamide (IFX), cisplatin (CDDP), and vinorelbine (VNB) as neoadjuvant chemotherapy (NAC) for untreated advanced cervical carcinoma (ACC). Between October 1995 and February 1998, 40 patients were entered in this study. Their median age was 43 years (range: 23-74 years). International Federation of Gynecology and Obstetrics stages were: IIB, 23; IIIB, 13; and IVA, 4. Therapy consisted of: IFX 2,000 mg/m2 1-hour (H) IV infusion days 1 to 3; 2-mercaptoethanesulfonic acid sodium salt (mesna) 400 mg/m2 IV bolus H 0 and 4, and 800 mg/m2 by mouth H 8, days 1 to 3; VNB 25 mg/m2 20-minute IV infusion days 1 and 8; and CDDP 75 mg/m2 IV day 3. Cycles were repeated every 28 days for a total of three courses. Both staging and response (R) assessment were performed by a multidisciplinary team. An objective response (OR) was observed in 24 of 40 patients (60%; 95% confidence interval, 45-75%). Four patients achieved complete response (CR) (10%); 20 partial response (50%); 12 patients stable disease (30%); and 4 progressive disease (10%). Eight of 24 patients (33%) with OR underwent radical surgery, and histologic CRs were recorded in 2 of them. The remaining patients received definitive radiotherapy after NAC. The dose-limiting toxicity was myelosuppression. Leukopenia occurred in 32 patients (80%) and was grade III or IV in 14 patients (36%). Peripheral neuropathy occurred in 9 patients (22%), whereas myalgias occurred in 10 (25%). Constipation was observed in 9 patients (23%); emesis occurred in 35 patients (88%). There were no therapy-related deaths. These results indicate that IFX/CDDP/VNB is an active combination for ACC with moderate toxicity. Implementation of this regimen in a multimodal therapy protocol deserves further study.

Background The aim of this study was to compare nutrition-related adverse events and clinical outcomes of ifosfamide, carboplatin, and etoposide regimen (ICE therapy) and ranimustine, carboplatin, etoposide, and cyclophosphamide regimen (MCEC therapy) instituted as pretreatment for autologous peripheral blood stem cell transplantation. Material/Methods We enrolled patients who underwent autologous peripheral blood stem cell transplantation between 2007 and 2012. Outcomes were compared between ICE therapy (n=14) and MCEC therapy (n=14) in relation to nutrient balance, engraftment day, and length of hospital stay. In both groups, we compared the timing of nutrition-related adverse events with oral caloric intake, analyzed the correlation between length of hospital stay and duration of parenteral nutrition, and investigated the association between oral caloric intake and the proportion of parenteral nutrition energy in total calorie supply. Five-year survival was compared between the groups. Results Compared with the MCEC group, the ICE group showed significant improvement in oral caloric intake, length of hospital stay, and timing of nutrition-related adverse events and oral calorie intake, but a delay in engraftment. Both groups showed a correlation between duration of parenteral nutrition and length of hospital stay (P=0.0001) and between oral caloric intake (P=0.0017) and parenteral nutrition energy sufficiency rate (r=−0.73, P=0.003; r=−0.76, P=0.002). Five-year survival was not significantly different between the groups (P=0.1355). Conclusions Our findings suggest that compared with MCEC therapy, ICE therapy improves nutrition-related adverse events and reduces hospital stay, conserving medical resources, with no significant improvement in long-term survival. The nutritional pathway may serve as a tool for objective evaluation of pretreatment for autologous peripheral blood stem cell transplantation. PMID:29398693

Based on the results of the ISG/OS-1 study, the MAP regimen (methotrexate [MTX], doxorubicin [ADM] and cisplatin [CDP] with the addition of ifosfamide [IFO] in poor-responder patients) was investigated in patients with nonmetastatic osteosarcoma of the extremity (ISG/OS-Oss study). Compared with the ISG/OS-1 study (cumulative doses: ADM 420 mg/m(2), MTX 120 g/m(2), CDP 600 mg/m(2), IFO 30 g/m(2)), the ISG/OS-Oss study reduced the number of MTX cycles from 10 to 5 (cumulative MTX dose: 60 g/m(2)) in order to diminish treatment duration and toxicity. From January 2007 to June 2011, 171 patients (median age 16 years, 60% males) were registered. The limb salvage rate was 94% and the good pathologic response rate 51% (these figures were 92% and 48%, respectively, in the ISG/OS-1 study). At a median follow-up of 39 months (range, 4-80), the 5-year overall survival rate was 80% (95% CI, 73%-87%) and the event-free survival was 50% (95% CI, 39%-59%). For comparison, the 5-year overall and event-free survival rates in ISG/OS-1 were 73% (95% CI, 65%-81%) and 64% (95% CI, 56%-73%), respectively. This study confirms that in nonmetastatic osteosarcoma of the extremity, conservative surgery in more than 90% and a good pathologic response rate of 50% can be expected with primary chemotherapy based on the MAP regimen. The response and resection rates in the ISG/OS-Oss study are in the same range as those of the previous study, whereas the event-free survival is lower than that previously achieved. Since the only difference between the two studies was the cumulative dose of postoperatively given MTX, our data support the importance of the cumulative dose of MTX in the MAP regimen.

We have reported the efficacy of the salvage chemotherapy P-IMVP16/CBDCA for patients with diffuse large B cell lymphoma (DLBCL) who had previously received CHOP before the availability of rituximab (R). Here, we confirmed the efficacy of R combined with P-IMVP16/CBDCA as a salvage chemotherapy for patients with DLBCL, who had previously received R-CHOP. We retrospectively analysed 59 patients with relapse or refractory DLBCL (38 male patients and 21 female patients) presenting between June 2004 and June 2013. The patients received R 375 mg/m 2 on day 1, methylprednisolone 1000 mg/body for 3 days (from day 3 to day 5), ifosfamide 1000 mg/m 2 for 5 days (from day 3 to day 7), methotrexate 30 mg/m 2 on day 5 and day 12, etoposide 80 mg/m 2 for 3 days (from day 3 to day 5), and carboplatin 300 mg/m 2 on day 3 every 21 days. Patients aged 70 years or older were given 75% of the standard dose. The overall response rate (complete response + partial response) was 64.4%. The 2-year overall survival rate was 55.3%. The 2-year progression free survival rate was 34.7%. The 2-year overall survival rate was 61.5% for the relapse patients, and 15.6% for the refractory patients (p < 0.0001). One patient died because of sepsis related to the treatment regimen. Non-hematological adverse effects were mild and tolerable. The R-P-IMVP-16/CBDCA regimen displayed a significant activity in relapsed DLBCL, with acceptable toxicity, and should be considered a candidate for salvage chemotherapy.

Purpose This study was conducted to determine whether there is contamination on exterior drug packaging using shipping totes from the distributor and carousel storage bins as surrogate markers of external packaging contamination. Methods A two-part study was conducted to measure the presence of 5-fluorouracil, ifosfamide, cyclophosphamide, docetaxel and paclitaxel using surrogate markers for external drug packaging. In Part I, 10 drug distributor shipping totes designated for transport of hazardous drugs provided a snapshot view of contamination from regular use and transit in and out of the pharmacy. An additional two totes designated for transport of non-hazardous drugs served as controls. In Part II, old carousel storage bins (i.e. those in use pre-study) were wiped for snapshot view of hazardous drug contamination on storage bins. New carousel storage bins were then put into use for storage of the five tested drugs and used for routine storage and inventory maintenance activities. Carousel bins were wiped at time intervals 0, 8, 16 and 52 weeks to measure surface contamination. Results Two of the 10 hazardous shipping totes were contaminated. Three of the five-old carousel bins were contaminated with cyclophosphamide. One of the old carousel bins was also contaminated with ifosfamide. There were no detectable levels of hazardous drugs on any of the new storage bins at time 0, 8 or 16 weeks. However, at the Week 52, there was a detectable level of 5-FU present in the 5-FU carousel bin. Conclusions Contamination of the surrogate markers suggests that external packaging for hazardous drugs is contaminated, either during the manufacturing process or during routine chain of custody activities. These results demonstrate that occupational exposure may occur due to contamination from shipping totes and storage bins, and that handling practices including use of personal protective equipment is warranted.

This multicentric study aimed to bring neuroblastoma patients together under IPOG-NBL-92 protocol and evaluate the results within the period between 1992 and 2001 in Izmir. Sixty-seven neuroblastoma patients from 4 pediatric oncology centers in Izmir were included in the study. IPOG-NBL-92 protocol modified from German Pediatric Oncology (GPO)-NB-90 protocol was applied: Patients in stage 1 received only surgery, while surgery plus 4 chemotherapy courses (cisplatin, vincristine, ifosfamide) were given in stage 2 and surgery plus 6 chemotherapy courses (cisplatin, vincristine, ifosfamide, epirubicin, cyclophosphamide) were given in stages 3 and 4 patients. In patients who were kept in complete remission (CR), a maintenance therapy of one year was applied. Radiotherapy was given to the primary site following induction chemotherapy plus surgery in stages 3 and 4 patients with partial remission (PR). The stages of the patients were as follows: 5% in stage 1, 39% in stage 3, 49% in stage 4, and 7% in stage 4S. Primary tumor site was abdomen in 88% of cases. CR rates were as 100% in stage 1, 76% in stage 3, 35% in stage 4, and 75% in stage 4S. Relapse was observed in 32% of patients in a median of 19 months. The median follow-up time for survivors was 33 (17-102) months. Five-year OS rate was 31% and the EFS rate was 30% in all patients. Five-year overall and event-free survival rates were 63 and 30% in stage 3, but 6 and 5%, respectively, in stage 4 patients. Univariate analysis established that the age, stage, primary tumor site, and high LDH and NSE levels conferred a significant difference. The IPOG-NBL-92 protocol has proved to be satisfactory with tolerable toxicity and reasonable CR and survival rates. However, more effective treatments suitable to Turkey's social and economic conditions are urgently needed for children over 1 year of age with advanced neuroblastoma.

2016-01-01

Background. Ewing sarcoma (ES) is a high-grade malignant tumor that has skeletal and extraskeletal forms and consists of small round cells. In the head and neck region, reported localization of extraskeletal ES includes the larynx, thyroid gland, submandibular gland, nasal fossa, pharynx, skin, and parotid gland, but not the external ear canal. Methods. We present the unique case of a 2-year-old boy with extraskeletal ES arising from the external ear canal, mimicking auricular hematoma. Results. Surgery was performed and a VAC/IE (vincristine, adriamycin, cyclophosphamide alternating with ifosfamide, and etoposide) regimen was used for adjuvant chemotherapy for 12 months. Conclusion. The clinician should consider extraskeletal ES when diagnosing tumors localized in the head and neck region because it may be manifested by a nonspecific clinical picture mimicking common otorhinolaryngologic disorders.

Case reports have suggested that treatment with high-dose etoposide can result in development of a unique secondary leukemia. This study was designed to estimate the risk of developing leukemia for patients receiving conventional doses of etoposide along with cisplatin and bleomycin. We reviewed the records at Indiana University of all untreated patients entering clinical trials using etoposide at conventional doses (cumulative dose, 2000 mg/m2 or less) for germ cell cancer between 1982 and 1991. The records of all patients who received a chemotherapy regimen containing etoposide, ifosfamide, or cisplatin after failing to respond to primary chemotherapy were also reviewed. Between 1982 and 1991, 538 patients entered serial clinical trials with planned cumulative etoposide doses of 1500-2000 mg/m2 in combination with cisplatin plus either ifosfamide or bleomycin. Of these 538 patients, 348 received an etoposide combination as initial chemotherapy and 190 received etoposide as part of salvage treatment. To date, 315 patients are alive, with median follow-up of 4.9 years, and 337 patients have had follow-up beyond 2 years. Two patients (0.37%) developed leukemia. One developed acute undifferentiated leukemia with a t(4;11) (q21;q23) cytogenetic abnormality 2.0 years after starting etoposide-based therapy, and one developed acute myelomonoblastic leukemia with no chromosome abnormalities 2.3 years after beginning chemotherapy. During this period, several hundred patients were treated with etoposide-based chemotherapy and did not enter clinical trials. Three of these patients are known to have developed hematologic abnormalities, including one patient with acute monoblastic leukemia with a t(11;19)(q13;p13) abnormality. Secondary leukemia after treatment with a conventional dose of etoposide does occur, but the low incidence does not alter the risk-to-benefit ratio of etoposide-based chemotherapy in germ cell cancer. The reports of leukemia associated with high doses of etoposide emphasize the need for diligent follow-up of patients and make careful risk-to-benefit analysis imperative.

Certain amount of anticancer drugs is excreted in the urine of patients receiving anticancer drugs, and urinary scattering including anticancer drugs at excretion has become a route of anticancer drug contamination. Therefore, we developed an active carbon sheet (HD safe sheet-U) that prevented diffusion by adsorbing anticancer drugs including that excreted in urine. The present study conducted a performance evaluation of this sheet. The adsorption performance of active carbon to anticancer drug in the urine was evaluated by determining concentration changes in the active carbon suspension (5 mg/mL) of 14 kinds of anticancer drugs (cyclophosphamide, ifosfamide, carboplatin, cisplatin, methotrexate, 5-fluorouracil, cytarabine, gemcitabine, doxorubicin, epirubicin, paclitaxel, docetaxel, etoposide, and irinotecan) diluted with artificial urine. Adhesion of the anticancer drug dropping on the sheet to a slipper sole was evaluated because urine including anticancer drugs is scattered on the floor, which can spread by adhering to shoe soles of patients and healthcare workers. The performance of the active carbon sheet was compared with two other types of medical adsorption sheets used as control sheets. Anticancer drugs diluted with artificial urine (1 mL) were dropped on the active carbon sheet and the two control sheets. The sheets were trod with slippers made by polyvinyl chloride. The adhered anticancer drug was wiped off and its quantity was determined. A remarkable decrease in anticancer drug concentrations, except for cisplatin, was detected by mixture of active carbon in the artificial urine (0-79.6%). The quantity of anticancer drug adhesion to slipper soles from the active carbon sheet was significantly lower compared with that observed for the two control sheets for eight kinds of anticancer drugs (cyclophosphamide, ifosfamide, carboplatin, methotrexate, cytarabine, gemcitabine, doxorubicin, and docetaxel). There was no adhesion in cyclophosphamide and docetaxel. Furthermore, the quantities of adhesion in cytarabine, gemcitabine, doxorubicin, paclitaxel, and irinotecan were lower than determination limit. Active carbon might be effective in adsorbing urinary anticancer drugs. The active carbon sheet adsorbed urinary excreted anticancer drugs, and use of such sheets might prevent diffusion of contamination due to urinary excreted anticancer drugs.

Osteosarcoma is the most common malignant bone tumour. Due to the high metastasis rate and drug resistance of this disease, multi-drug regimens are necessary to control tumour cells at various stages of the cell cycle, eliminate local or distant micrometastases, and reduce the emergence of drug-resistant cells. Many adjuvant chemotherapy protocols have shown different efficacies and controversial results. Therefore, we classified the types of drugs used for adjuvant chemotherapy and evaluated the differences between single- and multi-drug chemotherapy regimens using network meta-analysis. We searched electronic databases, including PubMed (MEDLINE), EmBase, and the Cochrane Library, through November 2016 using the keywords "osteosarcoma", "osteogenic sarcoma", "chemotherapy", and "random*" without language restrictions. The major outcome in the present analysis was progression-free survival (PFS), and the secondary outcome was overall survival (OS). We used a random effect network meta-analysis for mixed multiple treatment comparisons. We included 23 articles assessing a total of 5742 patients in the present systematic review. The analysis of PFS indicated that the T12 protocol (including adriamycin, bleomycin, cyclophosphamide, dactinomycin, methotrexate, cisplatin) plays a more critical role in osteosarcoma treatment (surface under the cumulative ranking (SUCRA) probability 76.9%), with a better effect on prolonging the PFS of patients when combined with ifosfamide (94.1%) or vincristine (81.9%). For the analysis of OS, we separated the regimens to two groups, reflecting the disconnection. The T12 protocol plus vincristine (94.7%) or the removal of cisplatinum (89.4%) is most likely the best regimen. We concluded that multi-drug regimens have a better effect on prolonging the PFS and OS of osteosarcoma patients, and the T12 protocol has a better effect on prolonging the PFS of osteosarcoma patients, particularly in combination with ifosfamide or vincristine. The OS analysis showed that the T12 protocol plus vincristine or the T12 protocol with the removal of cisplatinum might be a better regimen for improving the OS of patients. However, well-designed randomized controlled trials of chemotherapeutic protocols are still necessary.

Single-agent taxanes are commonly used as salvage systemic therapy for patients with advanced urothelial carcinoma (UC). To study the impact of combination chemotherapy delivering a taxane plus other chemotherapeutic agents compared with single-agent taxane as salvage therapy. Individual patient-level data from phase 2 trials of salvage systemic therapy were used. Trials evaluating either single agents (paclitaxel or docetaxel) or combination chemotherapy (taxane plus one other chemotherapeutic agent or more) following prior platinum-based therapy were used. Information regarding the known major baseline prognostic factors was required: time from prior chemotherapy, hemoglobin, performance status, albumin, and liver metastasis status. Cox proportional hazards regression was used to evaluate the association of prognostic factors and combination versus single-agent chemotherapy with overall survival (OS). Data were available from eight trials including 370 patients; two trials (n=109) evaluated single-agent chemotherapy with docetaxel (n=72) and cremophor-free paclitaxel (n=37), and six trials (n=261) evaluated combination chemotherapy with gemcitabine-paclitaxel (two trials, with n=99 and n=24), paclitaxel-cyclophosphamide (n=32), paclitaxel-ifosfamide-nedaplatin (n=45), docetaxel-ifosfamide-cisplatin (n=26), and paclitaxel-epirubicin (n=35). On multivariable analysis after adjustment for baseline prognostic factors, combination chemotherapy was independently and significantly associated with improved OS (hazard ratio: 0.60; 95% confidence interval, 0.45-0.82; p=0.001). The retrospective design of this analysis and the trial-eligible population were inherent limitations. Patients enrolled in trials of combination chemotherapy exhibited improved OS compared with patients enrolled in trials of single-agent chemotherapy as salvage therapy for advanced UC. Prospective randomized trials are required to validate a potential role for rational and tolerable combination chemotherapeutic regimens for the salvage therapy of advanced UC. This retrospective study suggests that a combination of chemotherapy agents may extend survival compared with single-agent chemotherapy in selected patients with metastatic urothelial cancer progressing after prior chemotherapy.

Based on the randomised Euro-EWING99-R1 trial, vincristine, adriamycin, cyclophosphamide (VAC) may be able to replace vincristine, adriamycin, ifosfamide (VAI) in the treatment of standard-risk Ewing sarcoma. However some heterogeneity of treatment effect by gender was observed. The current exploratory study aimed at investigating the influence of gender on treatment efficacy and acute toxicity. Impact of gender on event-free survival (EFS), acute toxicity by course, switches between treatment arms and cumulative dose of alkylating agents was evaluated in multivariable models adjusted for age including terms to test for heterogeneity of treatment effect by gender. The analysis of the EFS was performed on the intention-to-treat population. EFS did not significantly differ between the 509 males and 347 females (p=0.33), but an interaction in terms of efficacy was suspected between treatment and gender (p=0.058): VAC was associated with poorer EFS than VAI in males, hazard ratio (HR) (VAC/VAI)=1.37 [95% confidence interval (CI), 0.98-1.90], contrasting with HR=0.81 [95%CI, 0.53-1.24] in females. Severe toxicity was more frequent in females, whatever the toxicity type. Thirty patients switched from VAI to VAC (9/251 males, 4%, and 21/174 females, 12%) mostly due to renal toxicity, and three from VAC to VAI (2/258 males, 0.8%, and 1/173 females, 0.6%). A reduction of alkylating agent cumulative dose >20% was more frequent in females (15% versus 9%, p=0.005), with no major difference between VAC and VAI (10% versus 13%, p=0.15). Differences of acute toxicity rate and cumulative doses of alkylating agents could not explain the marginal interaction observed in the Euro-EWING99-R1 trial data. Effects of gender-dependent polymorphism/activity of metabolic enzymes (e.g. known for CYP2B6) of ifosfamide versus cyclophosphamide should be explored. External data are required to further evaluate whether there is heterogeneity of alkylating agent effect by gender. NCT00987636 and EudraCT 2008-003658-13. Copyright © 2015 Elsevier Ltd.

We report on feasibility of preoperative chemotherapy with or without radiation therapy (RT) in the context of a phase III randomized clinical trial involving localized, high-risk, soft tissue sarcomas. Of 321 eligible patients, 161 were randomly assigned to three preoperative cycles of epirubicin 120 mg/m(2) plus ifosfamide 9 g/m(2), and 160 were randomly assigned to three preoperative plus two postoperative cycles. Among them, 303 patients were included in this analysis; 169 were male and 134 were female, with a median age of 48 years (range, 15 to 79 years). One hundred fifty-two patients received concurrent RT preoperatively at a total dose of 44 to 50 Gy. Preoperative chemotherapy-related hematologic toxicity and early postoperative complications were reported. The influence of RT, age, and sex on hematologic grade 3 or 4 toxicities and wound complications was analyzed. Chemotherapeutic dose intensity (DI) was analyzed. Among the patients, 61.4%, 22.4%, and 23.8% experienced, grade 4 leucopenia, grade 3 or 4 anemia, and grade 3 or 4 thrombocytopenia, respectively. Respective rates were 66.4%, 24.3%, and 31.6% when RT was added preoperatively, and 56.3%, 20.5%, and 15.9% when preoperative chemotherapy was administered alone. Patient age affected grade 3 or 4 thrombocytopenia. Grade 4 leucopenia and grade 3 or 4 anemia presented 2.5 times more frequently in female patients than in male patients. Wound complications were observed in 13.5% of patients: 17% with preoperative RT and 10% without. Chemotherapeutic DI was greater than 90%, even in patients receiving preoperative RT and in patients age 65 years or older. This preoperative chemotherapy is feasible and can also be proposed for selected elderly patients. Grade 3 or 4 hematologic toxicity was common, but DI was excellent. Concurrent preoperative RT is safe, although an increased rate of grade 4 thrombocytopenia and limited increase in wound complications may be observed. © 2015 by American Society of Clinical Oncology.

In this study we explored whether a standard chemotherapy regimen consisting of mitoguazone, ifosfamide, methotrexate and etoposide (MIME) combined with 5 micrograms/kg or 10 micrograms/kg G-CSF was capable of mobilizing peripheral blood progenitor cells (PBPC) in lymphoma patients. Thirty-three patients with Hodgkin's disease (HD) and 108 patients with non-Hodgkin's lymphoma (NHL) were mobilized with MIME/G-CSF. Most patients were heavily treated with different chemotherapy regimens receiving a median of 11 cycles (range 3-40) of chemotherapy prior to mobilization. Eight of 141 patients failed to mobilize PBPC and bone marrow was harvested. In addition, 10 patients obtained a harvest of < 2.0 x 10(6) CD34+ cells/kg. More than 2.0 x 10(6) CD34+ cells/kg were achieved in all HD patients and in 83% of the NHL patients. Fifty-eight per cent of the patients harvested > or = 5 x 10(6) CD34+ cells/kg. Eleven per cent of the patients developed neutropenic fever during the mobilization and 3% had nadir platelet values below 20 x 10(9)/L. An inverse correlation was observed in high-grade NHL (H-NHL) patients between the number of chemotherapy cycles given before mobilization and yield of CD34+ cells. Such an association was not seen among patients with HD, transformed and low-grade NHL. When G-CSF 10 micrograms/kg was used in combination with MIME, this correlation was no longer seen in patients with H-NHL. There was also association between CD34+ cell yield and prior radiotherapy in patients with HD or transformed NHL or low-grade NHL. These results demonstrate that an ordinary salvage chemotherapy regimen, such as MIME combined with G-CSF, can be successfully used to mobilize PBPC. Although no significant effect of increased dose of G-CSF was found, our data suggest that MIME/G-CSF 10 micrograms/kg should preferentially be used to mobilize PBPC in H-NHL patients pre-treated with > or = 12 cycles of chemotherapy, in irradiated HD patients and in all low-grade and transformed lymphomas.

Previous trials from our group suggested an overall survival benefit with five cycles of adjuvant full-dose epirubicin plus ifosfamide in localised high-risk soft-tissue sarcoma of the extremities or trunk wall, and no difference in overall survival benefit between three cycles versus five cycles of the same neoadjuvant regimen. We aimed to show the superiority of the neoadjuvant administration of histotype-tailored regimen to standard chemotherapy. For this international, open-label, randomised, controlled, phase 3, multicentre trial, patients were enrolled from 32 hospitals in Italy, Spain, France, and Poland. Eligible patients were aged 18 years or older with localised, high-risk (high malignancy grade, 5 cm or longer in diameter, and deeply located according to the investing fascia), soft-tissue sarcoma of the extremities or trunk wall and belonging to one of five histological subtypes: high-grade myxoid liposarcoma, leiomyosarcoma, synovial sarcoma, malignant peripheral nerve sheath tumour, and undifferentiated pleomorphic sarcoma. Patients were randomly assigned (1:1) to receive three cycles of full-dose standard chemotherapy (epirubicin 60 mg/m 2 per day [short infusion, days 1 and 2] plus ifosfamide 3 g/m 2 per day [days 1, 2, and 3], repeated every 21 days) or histotype-tailored chemotherapy: for high-grade myxoid liposarcoma, trabectedin 1·3 mg/m 2 via 24-h continuous infusion, repeated every 21 days; for leiomyosarcoma, gemcitabine 1800 mg/m 2 on day 1 intravenously over 180 min plus dacarbazine 500 mg/m 2 on day 1 intravenously over 20 min, repeated every 14 days; for synovial sarcoma, high-dose ifosfamide 14 g/m 2 , given over 14 days via an external infusion pump, every 28 days; for malignant peripheral nerve sheath tumour, intravenous etoposide 150 mg/m 2 per day (days 1, 2, and 3) plus intravenous ifosfamide 3 g/m 2 per day (days 1, 2, and 3), repeated every 21 days; and for undifferentiated pleomorphic sarcoma, gemcitabine 900 mg/m 2 on days 1 and 8 intravenously over 90 min plus docetaxel 75 mg/m 2 on day 8 intravenously over 1 h, repeated every 21 days. Randomisation was stratified by administration of preoperative radiotherapy and by country of enrolment. Computer-generated random lists were prepared by use of permuted balanced blocks of size 4 and 6 in random sequence. An internet-based randomisation system ensured concealment of the treatment assignment until the patient had been registered into the system. No masking of treatment assignments was done. The primary endpoint was disease-free survival. The primary and safety analyses were planned in the intention-to-treat population. We did yearly futility analyses on an intention-to-treat basis. The study was registered with ClinicalTrials.gov, number NCT01710176, and with the European Union Drug Regulating Authorities Clinical Trials, number EUDRACT 2010-023484-17, and is closed to patient entry. Between May 19, 2011, and May 13, 2016, 287 patients were randomly assigned to a group (145 to standard chemotherapy and 142 to histotype-tailored chemotherapy), all of whom, except one patient assigned to standard chemotherapy, were included in the efficacy analysis (97 [34%] with undifferentiated pleomorphic sarcoma; 64 [22%] with high-grade myxoid liposarcoma; 70 [24%] with synovial sarcoma; 27 [9%] with malignant peripheral nerve sheath tumour; and 28 [10%] with leiomyosarcoma). At the third futility analysis, with a median follow-up of 12·3 months (IQR 2·75-28·20), the projected disease-free survival at 46 months was 62% (95% CI 48-77) in the standard chemotherapy group and 38% (22-55) in the histotype-tailored chemotherapy group (stratified log-rank p=0·004; hazard ratio 2·00, 95% CI 1·22-3·26; p=0·006). The most common grade 3 or higher adverse events in the standard chemotherapy group (n=125) were neutropenia (107 [86%]), anaemia (24 [19%]), and thrombocytopenia (21 [17%]); the most common grade 3 or higher adverse event in the histotype-tailored chemotherapy group (n=114) was neutropenia (30 [26%]). No treatment-related deaths were reported in both groups. In agreement with the Independent Data Monitoring Committee, the study was closed to patient entry after the third futility analysis. In a population of patients with high-risk soft-tissue sarcoma, we did not show any benefit of a neoadjuvant histotype-tailored chemotherapy regimen over the standard chemotherapy regimen. The benefit seen with the standard chemotherapy regimen suggests that this benefit might be the added value of neoadjuvant chemotherapy itself in patients with high-risk soft-tissue sarcoma.

Agrawal, D; Lahiri, T K; Lakhotia, S; Singh, Deepak

2014-01-01

Haemangiopericytoma is a rare soft tissue tumour characterised by tightly packed tumour cells situated around thin walled endothelial lined vascular channels, ranging from capillary sized vessels to large gaping sinusoidal spaces. The tumour cells are surrounded by reticulin and are negative for muscle, nerve and epithelial markers. The diagnosis of extra-pulmonary intra-thoracic, extra-pleural mediastinal mass is difficult. It constitutes only 6% of all primary tumours and cysts of the mediastinum. We report the rare occurrence of primary intra-thoracic, extra-pulmonary mediastinal haemangiopericytoma of mesenchymal origin with perivascular localisation. The patient underwent right postero-lateral thoracotomy and post-operatively received chemotherapy with adriamycin (60 mg/m2) on day 1 and ifosfamide (1.5 g/m2) on day 1 to 3. Thirty-seven months after the operation, the patient has been well with evidence of a single recurrence in the left lower lobe.

Primary rhabdomyosarcoma of the breast is very rare disease with poor prognosis and no definitive treatment has yet been established. A 17-year-old girl presented with right breast mass without distant metastasis in image study. The result of core needle biopsy was intraductal carcinoma; however, histopathologic finding after mastectomy was primary rhabdomyosarcoma of breast. Adjuvant chemotherapy was recommended because resection margin was involved by tumor cells, but she did not visit the clinic anymore. Five months later, tumor recurred with local invasion and chemotherapy of vincristine, doxorubicin, and cyclophosphamide alternating with ifosfamide and etoposide (VAC/IE) was done. In the course of chemotherapy and sequential follow-up, there was no tumor growth until now. Primary breast rhabdomyosarcoma is an uncommon disease, as a result diagnosis is often delayed. For the same reason, there is little information about treatment. This report may be helpful for managing the disease.

Serviço de Oncologia Médica. Instituto Português de Oncologia Francisco Gentil. Porto. Portugal. A 27-year-old man, smoker, presented with three months history of fever. A left pulmonary mass inseparable from the heart was identified and serum alpha-fetoprotein was 4160 ng/ml. The morphologic aspects and immunohistochemistry of the biopsy specimen, in conjunction with the clinical findings were compatible with a diagnosis of pulmonary blastoma with germ cell differentiation. The tumour was considered unresectable. The patient was submitted to two cycles of primary chemotherapy with bleomycin, etoposide and cisplatin. Despite a reduction in serum alpha-fetoprotein, the tumor did not regress. Second line chemotherapy (with paclitaxel, ifosfamide and cisplatin) was instituted, but progressive disease was identified after 2 cycles. Six months after the diagnosis cerebral metastases were found and the patient died. This case illustrates a rare situation of difficult diagnosis and treatment.

Multiple mechanisms of drug resistance contribute to treatment failure. Although high-dose therapy attempts to overwhelm these defenses pharmacologically, this approach is only successful in a fraction of treated patients. Many drug resistance mechanisms are shared between malignant and normal cells, but the expression of various drug resistance mechanisms associated with hypoxia is largely confined to tumor tissue. Thus, reversal of this mechanism is likely to provide a therapeutic advantage to the host. This study was designed to define the dose-limiting toxicities and maximum tolerated dose of etanidazole when it is given concurrently with high-dose ifosfamide, carboplatin, and etoposide (ICE), with hematopoietic stem cell support. The maximum tolerated doses of high-dose ICE were administered concurrently with dose escalations of etanidazole, a hypoxic cell sensitizer. All agents were given by 96-h continuous i.v. infusion beginning on day -7. Mesna uroprotection was provided. Autologous marrow and cytokine mobilized peripheral blood progenitor cells were reinfused on day 0. Granulocyte colony-stimulating factor was administered following reinfusion until the granulocytes recovered to > 1000/microliter. Fifty-five adults with advanced malignancies were enrolled in cohorts of five to nine patients. Four dose levels of etanidazole between 3 and 5.5 g/m2/day (12, 16, 20, and 22 g/m2 total doses) and two doses of carboplatin (1600 and 1800 mg/m2 total doses) were evaluated. Seven patients died of organ toxicity (13%); two each from veno-occlusive disease of liver and sepsis; and one each from sudden death, renal failure, and refractory thrombocytopenic hemorrhage. Five deaths occurred at the top dose level. One additional patient suffered a witnessed cardiorespiratory arrest from ventricular fibrillation and was resuscitated. Dose-dependent and largely reversible peripheral neuropathy was observed consisting of two syndromes: severe cramping myalgic/neuralgic pain, predominantly in stocking glove distribution, occurring between day -3 and day 0, and a sensory peripheral neuropathy with similar distribution peaking around day +60. The maximal achievable dose of etanidazole (16 g/m2 dose level) resulted in a mean serum level of 38 micrograms/ml (25-55 micrograms/ml). Etanidazole significantly enhanced host toxicity of high-dose ICE. Effective modulatory doses of etanidazole could not be given with acceptable toxicity using this schedule.

The case of a 27-year-old Hispanic female who presented with an occipito-parietal tumor after suffering trauma to the area. A physical examination revealed no tenderness to palpation and with evidence of healing ulcerations. The biopsy was consistent with a synovial sarcoma. A wide excision of the mass (15cm x 14cm x 6cm) followed by a pericranial flap was performed. A follow-up CT showed recurrence involving the parietal sagittal sinus. After a second biopsy the mass was determined to be a small-cell sarcoma, consistent with Ewing's sarcoma. Chemotherapy included 8 cycles of doxorubicin, vincristine, and cyclophosphamide, with alternating cycles of etoposide and ifosfamide. A year later, a second wide excision of the mass was performed, followed by bilaminate skin substitute and skin graft placement for reconstruction of the soft-tissue defect. After chemotherapy, a follow-up PET scan showed no signs of re-uptake in any soft tissue or skeletal structures. After 2 years, the patient remains in complete remission.

Hemorrhagic cystitis (HC) is a known complication of oxazophosphorine chemotherapy. BK virus (BKV) has been commonly found to be associated with hematuria in stem cell transplant patients; however, it has rarely been reported after cyclophosphamide chemotherapy alone. The authors present 3 cases of BK viruria with HC in nontransplant pediatric oncology patients. The 3 patients with BKV had more prolonged hematuria (14 to 16 wk) compared with 1 patient with BKV-negative HC (10 wk). The HC necessitated chemotherapy delays and also prolonged supportive care. One patient was treated with intravenous cidofovir with resolution of BK viruria and hematuria. BKV may have an association with the development of HC in nonstem cell transplant patients receiving high-dose oxazophosphorine chemotherapy. HC may present early and be more prolonged in patients with BK viruria. Patients with HC after cyclophosphamide or ifosfamide with negative bacterial cultures should be studied for BKV. Cidofovir may be beneficial in certain patients with BK viruria and HC; however, definitive data will require a clinical trial.

Cellular and Molecular Actions of Methylene Blue in the Nervous System

Methylene Blue (MB), following its introduction to biology in the 19th century by Ehrlich, has found uses in various areas of medicine and biology. At present, MB is the first line of treatment in methemoglobinemias, is used frequently in the treatment of ifosfamide-induced encephalopathy, and is routinely employed as a diagnostic tool in surgical procedures. Furthermore, recent studies suggest that MB has beneficial effects in Alzheimer's disease and memory improvement. Although the modulation of the cGMP pathway is considered the most significant effect of MB, mediating its pharmacological actions, recent studies indicate that it has multiple cellular and molecular targets. In the majority of cases, biological effects and clinical applications of MB are dictated by its unique physicochemical properties including its planar structure, redox chemistry, ionic charges, and light spectrum characteristics.

This study was aimed to evaluate the efficacy of G-CSF (Granulocyte colony stimulating factor) administration to 37 patients with neutropenia following intensive combination chemotherapy. The patients were divided into two subgroups including solid tumors given ifosfamide and etoposide combination chemotherapy (IMET subgroup) and acute myeloid leukemia (AML) patients treated with mitoxantrone and cytarabine. Control group consisted of 31 acute myeloid leukemia patients. G-CSF was started on the first day of absolute neutropenia until the absolute neutrophil count was above 1000/mm(3) for two consecutive days. G-CSF was found to be effective for early recovery of neutrophil count. Expected response was achieved within 14 days in 91.5% of the courses with a median of fifth day of G-CSF treatment. In conclusion, this study showed the efficacy of G-CSF in early recovery of neutrophil count without any reduction in the incidence of febrile episodes and documented rates of bacterial and fungal infections in patients with acute myeloid leukemia.

Primitive neuroectodermal tumors (PNET) represent 1% of sarcomas. Head and neck peripheral PNETs have an intermediate prognosis between abdominopelvic disease and extremities. We here report the case of a 40-year old male who presented with primitive neuroectodermal tumor of the thyroid and was treated by multimodal treatment, including surgery, chemotherapy and intermediate dose radiotherapy. The patient is alive and fit with a functional larynx at 27 months. Multimodal treatments yield five-year survival rates of about 60%. Major drug regimens use vincristine, doxorubicin, ifosfamide or cyclophosphamide, dactinomycin and/or etoposide. Complete surgical excision is undertaken whenever possible to improve long-term survival. However, the relative radiosensitivity of tumors of the Ewing family, suggest multimodal treatment including adjuvant conformal radiotherapy in case of positive margins or poor response to chemotherapy rather than resection with 2-3 cm margins, which would imply laryngeal sacrifice for thyroid tumors. The role of expert rare tumor networks is crucial for optimal decision-making and management of such rare tumors on a case by case basis.

The effects of a novel salvage regimen, IDEA (ifosfamide, cytosine arabinoside, etoposide and dexamethasone), which does not include anthracycline or platinum, in patients with non-Hodgkin's lymphoma (NHL) were examined. Thirty-four patients with refractory or relapsed NHL were treated with IDEA. The overall remission and complete remission rates were 67.6% and 35.3%, respectively. The toxicity of IDEA was tolerable. With a median follow-up of 14 months, one-year overall survival (OS) and progression-free survival rates were 75.1% and 43.7%, respectively. Adequate numbers of CD34(+) cells were obtained in 77.8% of the patients assigned to receive autologous peripheral blood stem cell (PBSC) transplantation. High-dose chemotherapy with autologous PBSC transplantation was carried out in 14 patients; their 3-year OS was 75.0%, with a median follow-up of 38 months. IDEA is an effective second-line chemotherapy regimen for NHL patients and has an excellent PBSC-mobilizing effect.

Natural killer/T-cell lymphoma (NKTCL) and its presentation with extranodal orbital involvement as a single lesion are extremely rare. The aim of this article was to describe the presentation, diagnosis, and systemic treatment of a primary orbital NKTCL. A 67-year-old Caucasian woman presented with left exophthalmos, pain, periorbital swelling, and limited extrinsic ocular motility. Orbital cellulitis was suspected, but finally orbital biopsy was performed due to no response to initial antibiotic and anti-inflammatory standard treatment. The pathologic diagnosis was NKTCL. Systemic evaluations were negative. CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy was initiated, but after 2 cycles of treatment, tumoral progression was observed. SMILE (dexamethasone, methotrexate, ifosfamide, L-asparaginase, etoposide) rescue chemotherapy was then administered. Lymphoma progression was inevitable. She died 10 months later. Although more nasal NKTCL cases have been described, the nonnasal primary orbital NKTCL is an uncommon neoplasm with high mortality rate, despite the recent use of more potent chemotherapy regimens.

Background Uterine carcinosarcomas are uncommon with about 35% not confined to the uterus at diagnosis. The survival of patients with advanced uterine carcinosarcoma is poor with pattern of failure indicating greater likelihood of upper abdominal and distant metastatic recurrence. Objectives To evaluate the effectiveness and safety of radiotherapy and/or systemic chemotherapy in the management of stage III-IV persistent or recurrent uterine carcinosarcoma. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL, The Cochrane Library 2010, Issue 2, MEDLINE and EMBASE to May 2010. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials comparing adjuvant radiotherapy and/or chemotherapy in women with uterine carcinosarcoma. Data collection and analysis We independently abstracted data and assessed risk of bias. We pooled hazard ratios (HRs) for overall and progression-free survival and risk ratios (RRs) comparing adverse events in women who received radiotherapy and/or chemotherapy in meta-analyses. Main results Three trials (579 women, of whom all were assessed at the end of the trials) met the inclusion criteria. Two trials (373 women with stage III-IV persistent or recurrent disease) found that women who received combination therapy had a significantly lower risk of death and disease progression than women who received single agent ifosfamide. There was no statistically significant difference in all reported adverse events, with the exception of nausea and vomiting, which affected significantly more women in the combination therapy group than in the ifosamide group. One trial found no statistically significant difference in the risk of death and disease progression in women who received whole abdominal irradiation and chemotherapy, after adjustment for age and FIGO stage (HR = 0.71, 95% CI 0.48 to 1.05 and HR = 0.79, 95% CI 0.53 to 1.18 for overall survival and progression-free survival respectively). There was no statistically significant difference in all reported adverse events, with the exception of haematological and neuropathy morbidities, which affected significantly fewer women in the whole body irradiation group than in the chemotherapy group (RR = 0.02, 95% CI 0.00 to 0.16). Authors’ conclusions The results of this review are limited to two trials. In the primary treatment/first line therapy of advanced stage metastatic uterine carcinosarcoma, as well as in recurrent disease, adjuvant combination chemotherapy with ifosfamide and paclitaxel should be considered. None of the included studies reported on quality of life. PMID:21249682

We report on the efficacy and toxicity of a sequential high-dose therapy with peripheral blood stem cell (PBSC) support in 85 patients with high-risk stage II/III breast cancer. There were 71 patients with more than nine tumour-positive axillary lymph nodes. An induction therapy of two cycles of ifosfamide (total dose, 7.5 g m−2) and epirubicin (120 mg m−2) was given, and PBSC were harvested during G-CSF-supported leucocyte recovery following the second cycle. The PBSC-supported high-dose chemotherapy consisted of two cycles of ifosfamide (total dose, 12 000 mg m−2), carboplatin (900 mg m−2) and epirubicin (180 mg m−2). Patients were autografted with a median number of 3.7 × 106 CD34+ cells kg−1 (range, 1.9–26.5 × 106) resulting in haematological reconstitution within approximately 2 weeks following high-dose therapy. The toxicity was moderate in general, and there was no treatment-related toxic death. Twenty-one patients relapsed between 3 and 30 months following the last cycle of high-dose therapy (median, 11 months). The probability of disease-free and overall survival at 4 years were 60% and 83%, respectively. According to a multivariate analysis, patients with stage II disease had a significantly better probability of disease-free survival (74%) in comparison to patients with stage III disease (36%). The probability of disease-free survival was also significantly better for patients with oestrogen receptor-positive tumours (70%) compared to patients with receptor-negative ones (40%). Bone marrow samples collected from 52 patients after high-dose therapy were examined to evaluate the prognostic relevance of isolated tumour cells. The proportion of patients presenting with tumour cell-positive samples did not change in comparison to that observed before high-dose therapy (65% vs 71%), but a decrease in the incidence and concentration of tumour cells was observed over time after high-dose therapy. This finding was true for patients with relapse and for those in remission, which argues against a prognostic significance of isolated tumour cells in bone marrow. In conclusion, sequential high-dose chemotherapy with PBSC support can be safely administered to patients with high-risk stage II/III breast cancer. Further intensification of the therapy, including the addition of non-cross resistant drugs or immunological approaches such as the use of antibodies against HER-2/NEU, may be envisaged for patients with stage III disease and hormone receptor-negative tumours. © 1999 Cancer Research Campaign PMID:10188897

Cyclosporin A and doxorubicin-ifosfamide in resistant solid tumours: a phase I and an immunological study.

In order to test whether circumvention of clinical resistance can be obtained in common solid tumours by targeting different drug resistance mechanisms, a phase I clinical and immunological study was designed. The purpose of the study was to determine the dose of cyclosporin A (CsA), in combination with doxorubicin (DOX) and ifosfamide (IFX), needed to achieve steady-state whole-blood levels of 2000 ng ml-1 and the associated toxicity of this combination. Treatment consisted of CsA 5 mg kg-1 as a 2 h loading infusion, followed by a CsA 3 day continuous infusion (c.i.) (days 1-3) at doses that were escalated from 10 to 18 mg kg-1 day-1. Chemotherapy consisted of DOX 55 mg m-2 by i.v. 24 h c.i. (day 2) and IFX 2 g m-2 i.v. over 1 h on days 1 and 3. Treatments were repeated every 4 weeks. Eighteen patients with previously treated resistant solid tumours received 39 cycles. Mean steady-state CsA levels > or = 2000 ng ml-1 were reached at 5 mg kg-1 loading dose followed by a 3 day c.i. of 16 mg kg-1 day-1 or greater. Haematological toxicity was greater than expected for the same chemotherapy alone. One patient died of intracranial haemorrhage due to severe thrombopenia. Other observed toxicities were: asymptomatic hyperbilirubinaemia (46% cycles), mild nephrotoxicity (20% cycles), hypomagnesaemia (72% cycles), mild increase in body weight (100% cycles), hypertension (15% cycles) and headache (15% cycles). Overall the toxicity was acceptable and manageable. No alterations in absolute lymphocyte number, the lymphocyte subsets studied (CD3, CD4, CD8, CD19) or CD4/CD8 ratio were observed in patients receiving more than one treatment cycle, although there were significant and non-uniform variations in the values of the different lymphocyte subsets studied when pre- and post-treatment values were compared. There was also a significant increase in the CD4/CD8 ratio. Tumour regressions were observed in two patients (epidermoid carcinoma of the cervix and Ewing's sarcoma). The CsA dose recommended for phase II trials is a 5 mg kg-1 loading dose followed by a 3-day c.i. of 16 mg kg-1 day-1 simultaneously with DOX and IFX at the doses administered in this study.

Patients with relapsed lymphoma can be cured with high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HSCT). New therapeutic approaches with better cytoreductive capacity are needed for relapsed patients to keep their chance for cure with transplantation. We report 30 patients with relapsed lymphoma, median age 43 years, treated with IIVP salvage regimen consisting of ifosfamide, mesna, idarubicin, and etoposide for 2 or 3 cycles. Seventeen patients had non-Hodgkin lymphoma (NHL) and 13 patients had Hodgkin disease (HD). Fourteen (47%) patients were at their first relapse. Overall response rate was 86.6% (n = 26) with 19 patients (63.3%) achieving complete response. Overall response rate was 92% in patients with HD and 82% in NHL. The most frequent side effects observed were grade III-IV neutropenia (87%) and thrombocytopenia (73%). IIVP regimen is a highly effective salvage therapy for patients with relapsed HD or NHL who are candidates for autologous HSCT. Close follow up is necessary because of the high incidence of grade III-IV hematologic toxicity.

A large-scale study was carried out in order to determine the contamination level of antineoplastic drugs in pharmacies and to investigate the suitability and effects of wipe sample monitoring at regular intervals. A specific study design was developed. The 130 participating pharmacies were divided into a study and a control group, carrying out five and two wipe sampling cycles, respectively. The work practice was analyzed using questionnaires to identify factors that influence the contamination level. From 1269 wipe samples, 774 (61%) were contaminated with at least one of the analyzed cytotoxic drugs: cyclophosphamide, docetaxel, etoposide, 5-fluorouracil, gemcitabine, ifosfamide, methotrexate, and paclitaxel. A significant decrease of the contamination with cyclophosphamide and 5-fluorouracil was observed in the study group. The Monitoring-Effect Study of Wipe Sampling in Pharmacies method has proven to be a reliable and affordable tool for contamination control. Based on the 90th percentile of the contamination values, a substance-independent performance-based guidance value of 0.1ng cm(-2) has been derived.

Synovial sarcoma (SVS) of the thyroid gland is exceedingly rare. We report the case of a 55-year-old man with a rapidly growing 7-cm neck mass. Because of suspicion of anaplastic thyroid carcinoma, a total thyroidectomy was planned, without preoperative cytology. During surgery, the tumor ruptured, leading to fragmented and incomplete resection. The morphological and immunohistochemical aspects suggested thyroid SVS, which was confirmed by fluorescent in situ hybridization (SYT gene rearrangement). The patient experienced immediate local relapse in close contact with large vessels and the thyroid cartilage and was referred to our institution. Doxorubicin-ifosfamide chemotherapy led to a minor response that authorized secondary conservative surgery. Because of microscopically incomplete resection, adjuvant radiotherapy was chosen and is ongoing 10 months after initial surgery. The prognosis of thyroid SVS is associated with a high risk for local and metastatic relapses. Pretreatment diagnosis is fundamental and may benefit from molecular analysis. Margin-free monobloc surgical excision is the best chance for cure, but adjuvant chemotherapy and radiotherapy deserve to be discussed. PMID:24575008

Extraskeletal Ewings sarcoma are rare tumors for which there is no consensus on optimal management. A retrospective review of the clinical features, treatment and outcome of patients with extraskeletal Ewings sarcoma who reported to a single institution between January 1992-December 2003 is reported. A total of 19 patients with extraskeletal Ewings sarcoma were identified. Of these, 4 patients had metastatic disease at presentation and 15 patients with non-metastatic disease received combined modality treatment with primary combination chemotherapy followed by local treatment with radiotherapy or surgery. Disease free survival and overall survival for patients with non metastatic disease after combined modality treatment were 60% and 30% respectively. The significant predictors for prolonged disease free survival and overall survival were high haemoglobin (p = 0.002), low lactate dehydrogenase (p = 0.028), chemotherapy with Vincristine, Adriamycin, Cyclophosphamide, Ifosfamide and Etoposide regime (p = 0.008) and complete response to chemotherapy (p = 0.001). Aggressive combination chemotherapy followed by complete surgery or radiotherapy to a dose of more than 50 Gy is essential to confer optimal outcome for patients with extraskeletal Ewings sarcoma.

Hirschsprung disease is a developmental disorder of the enteric nervous system that is characterized by absence of ganglion cells in the distal intestine, and it occurs in approximately 1 in every 500,000 live births. Hepatoblastoma is a malignant liver neoplasm that usually occurs in children aged 6 months to 3 years, with a prevalence of 0.54 cases per 100,000. A boy diagnosed with intestinal atresia in the first week of life progressed to a diagnosis of comorbid Hirschsprung disease. Congenital cataracts and sensorineural deafness were diagnosed. A liver mass developed and was subsequently confirmed to be a hepatoblastoma, which was treated by means of surgical resection of 70% of the liver volume and neoadjuvant chemotherapy (ifosfamide, cisplatin and doxorubicin). It is known that Hirschsprung disease may be associated with syndromes predisposing towards cancer, and that hepatoblastoma may also be associated with certain congenital syndromes. However, co-occurrence of hepatoblastoma and Hirschsprung disease has not been previously described. We have reported a case of a male patient born with ileal atresia, Hirschsprung disease and bilateral congenital cataract who was later diagnosed with hepatoblastoma.

A 59-year-old man presented with polyuria and polydipsia immediately following his sixth cycle of rituximab and bendamustine for chronic lymphocytic leukemia. He initially compensated by increasing his oral fluid intake at home, but later developed septic shock and was admitted with orders to be kept nil per os (NPO). This prompted an episode of acute hypernatremia during which he exhibited continued polyuria with inappropriately dilute urine. Desmopressin challenge yielded no response in the urine osmolality, indicating a nephrogenic source of his diabetes insipidus (DI). He had no known exposure to other causative agents and had demonstrated a robust response to chemotherapy. The patient became eunatremic once oral intake was resumed and his infection was treated. Two months after presentation, he remained symptomatic. A trial with hydrochlorothiazide resulted in a significant increase in urine osmolality and subsequent decrease in urine output. To our knowledge, this is the first case of nephrogenic diabetes insipidus after rituximab and bendamustine exposure. We propose that bendamustine, similar to the alkylating agent ifosfamide, is toxic to the glomerulus and proximal tubule cells and is the most likely cause of the patient's nephrogenic DI.

Encephalopathy due to hepatic or renal failure, electrolyte disturbances, or the administration of benzodiazepines and narcotics is commonly encountered, well reviewed in the literature, and, therefore, not usually missed. This article focuses on encephalopathies that were previously well described but may be overlooked by modern clinicians, as well as those that are still taught in the classroom but seldom thought of in practice. Due to the presumed relative rarity of these cases and emphasis on the well-memorized "classic" clinical presentations, these often treatable, and perhaps not so rare, encephalopathies due to systemic medical illness may go undiagnosed and untreated. Pancreatic encephalopathy, Wernicke's encephalopathy, and pellagra encephalopathy are reviewed in detail; cefepime and ifosfamide encephalopathies are discussed as examples of specific medication-induced encephalopathies. Septic encephalopathy, central pontine myelinolysis, and fat embolism syndrome are briefly reviewed. The encephalopathies reviewed have the potential for devastating neurological consequences if recognition and, therefore, treatment are delayed. Clinical improvement for many of these syndromes depends on prompt intervention. This article highlights some representative examples of less-commonly diagnosed metabolic and toxic encephalopathies.

Leiomyosarcoma: Principles of management.

PubMed

Martin-Liberal, Juan

2013-11-01

The term soft-tissue sarcomas (STS) embraces more than 50 different sub-types that are often associated with poor prognosis. Only a very limited number of agents are active against STS. Doxorubicin and ifosfamide are widely accepted as the most effective compounds. However, their low response rates and poor impact on the overall survival of the patients illustrate the need for new treatment options. Among them, leiomyosarcomas are one of the most frequently occurring subtypes. In spite of the relatively high incidence of leiomyosarcomas, the overall effectiveness of the currently available systemic treatments is still poor. The heterogeneity of its biological origin, clinical behavior and responsiveness to chemotherapy, together with the scarcity of successful clinical trials, makes the treatment of leiomyosarcoma especially challenging. In addition, the evidence-based treatment for leiomyosarcoma comes from trials in which, in the majority of cases, no distinctions have been made among the different STS sub-types. As a result, every therapeutic decision should be made on an individual basis in collaboration with the patient. The results of new specific histology-designed clinical trials should aid decision making in this complex field.

Mycosis fungoides is the most common form of cutaneous T-cell lymphoma. Both large-cell transformed mycosis fungoides and mycosis fungoides bullosa are rare presentations and predict unfavorable prognosis. We report the case of a 61-year-old woman who presented with generalized erythematous scaly annular plaques, and histopathology confirmed the diagnosis of mycosis fungoides. She was treated with various conventional therapies but only achieved partial response and always relapsed after discontinuation of treatment. Her last treatment was combined chemotherapy (CHOP regimen) followed by romidepsin. However, 1 month after the last cycle of romidepsin, she developed multiple ulcerative masses and nodules. Skin biopsy was compatible with CD30+ large cell transformation, and she was treated with a new combination of chemotherapy (ifosfamide, carboplatin, etoposide). One day after receiving chemotherapy, multiple tense bullae on normal-appearing skin and mycosis fungoid plaques erupted. A histological study demonstrated subepidermal blistering with epidermotropism of atypical lymphocytes. Direct immunofluorescence study was negative. The results confirmed the diagnosis of mycosis fungoides bullosa. We present the first reported case of large-cell transformed mycosis fungoides coexisting with mycosis fungoides bullosa.

Basidiocarp of Agaricus blazei (=Agaricus brasiliensis; =Agaricus subrufescens) is used as teas or capsules due to its antineoplastic effect but there are few reports of using mycelium for this purpose. The objective of this study was to evaluate the antineoplastic activity on sarcoma 180 cells implanted in mice of two forms of preparation of the mycelium from two A. blazei strains grown in culture medium with different concentrations of isolated soy protein. Mycelia were grown in Pontecorvo medium with different concentrations of isolated soybean protein (ISP). Mycelial hot water extract, moistened mycelial powder, hot water extract of green tea, Ifosfamida(®) (ifosfamide drug), and saline solution were administered daily by gavage in mice with sarcoma 180 cells to evaluate antineoplastic activity. It was concluded that antineoplastic activity was the same for both strains, except when used as moistened mycelial powder, which rules out the use of mycelial powder in capsules. Mycelial hot water extract had high antineoplastic activity with lower metabolic demand on the spleen and maintenance of normal blood parameters. Mycelial growth in different ISP concentrations had the same antineoplastic activity. Also the vegetative mycelium was as effective as the basidiocarp for sarcoma 180 tumor inhibition. Green tea was as effective as mycelial hot water extract.

Late renal toxicity of treatment for childhood malignancy: risk factors, long-term outcomes, and surveillance.

PubMed

Skinner, Roderick

2018-02-01

Chronic glomerular and tubular nephrotoxicity is reported in 20-50% and 20-25%, respectively, of children and adolescents treated with ifosfamide and 60-80% and 10-30%, respectively, of those given cisplatin. Up to 20% of children display evidence of chronic glomerular damage after unilateral nephrectomy for a renal tumour. Overall, childhood cancer survivors have a ninefold higher risk of developing renal failure compared with their siblings. Such chronic nephrotoxicity may have multiple causes, including chemotherapy, radiotherapy exposure to kidneys, renal surgery, supportive care drugs and tumour-related factors. These cause a wide range of chronic glomerular and tubular toxicities, often with potentially severe clinical sequelae. Many risk factors for developing nephrotoxicity, mostly patient and treatment related, have been described, but we remain unable to predict all episodes of renal damage. This implies that other factors may be involved, such as genetic polymorphisms influencing drug metabolism. Although our knowledge of the long-term outcomes of chronic nephrotoxicity is increasing, there is still much to learn, including how we can optimally predict or achieve early detection of nephrotoxicity. Greater understanding of the pathogenesis of nephrotoxicity is needed before its occurrence can be prevented.

Neoadjuvant chemotherapy in soft tissue sarcomas: latest evidence and clinical implications

PubMed Central

Pasquali, Sandro; Gronchi, Alessandro

2017-01-01

Soft tissue sarcomas are a rare and multifaceted group of solid tumours. Neoadjuvant chemotherapy is increasingly used to limit loss of function after wide surgical excision with the ultimate aim of improving patient survival. Recently, advances in the identification of effective treatment strategies and improvements in patient risk stratification have been reached. A randomized trial demonstrated that neoadjuvant epirubicin and ifosfamide improves survival of patients affected by five high-risk soft tissue sarcoma histologies of trunk and extremities, including undifferentiated pleomorphic sarcoma, myxoid liposarcoma, synovial sarcoma, malignant peripheral nerve sheath tumours, and leiomyosarcoma. Selection of patients for these treatments is expected to be improved by the eighth edition of the American Joint Committee on Cancer (AJCC) TNM staging system, as it tailors T-stage categories on primary tumour site and considers a prognostic nomogram for retroperitoneal sarcoma, which also includes soft tissue sarcoma histology and other patient and tumour features not directly included in the TNM staging. Within this framework, this article will present neoadjuvant treatment strategies for high-risk soft tissue sarcoma, emphasizing the most recent advances and discussing the need for further research to improve the effectiveness of neoadjuvant treatments.

This study investigated the TiO2 photocatalytic degradation and transformation of the oxazaphosphorines ifosfamide (IFO), cyclophosphamide (CP) and trofosfamide (TRO). Under the optimum conditions of TiO2=100mg/L, IFO=100μg/L and solution pH=5.5, IFO was completely removed within 10min (k=0.433min(-1)). The results indicated that OHfree radicals generated by valence holes in the bulk solution were the predominant species for the degradation of IFO. At higher initial concentrations of oxazaphosphorines (20mg/L), >50% of TOC remained after 6h of reaction time, indicating that parent compounds were transformed to byproducts, which exhibit higher Microtox acute toxicities; chlorinated byproducts were likely the source of toxicity. Photocatalytic degradation pathways of the three oxazaphosphorines were proposed. IFO, CP and TRO follow very similar pathways and bond-breaking processes: ketonization and breaking of the CCl bond, the PN bond and the CN bond (N-dechloroethylation). Chloride (Cl(-)) release is likely the first and primary step in the decomposition process. Several of the identified byproducts were also metabolites, which implies that photocatalytic oxidation proceeds through pathways that are similar to metabolic pathways.

We report a rare case of adult T cell leukemia/lymphoma (ATLL) in which cardiac invasion was clinically demonstrated and treated effectively. A 45-year-old female was admitted because of exertional dyspnea and cervical tumors. The leukocyte count was 19,100/microliters with 20% of flower cells. HTLV-I antibody was positive. She was diagnosed as ATLL and treated with VEPA. She got remission for a short duration which was followed by relapse. OPEC was started as salvage therapy. In the course, extensive pericardial effusion was found in chest X-P. Pericardial puncture demonstrated ATLL cells and high titer of free IL-2 receptor (57,400U/ml) in the effusion. It was diagnosed as pericardial invasion of ATLL cells. Chemotherapy was started with new combination of drugs (cisplatin, mitoxantrone, ifosfamide, and prednisolone). Concomitantly pericardial drainage was performed and the drugs were administered directly into the pericardial cavity. The clinical improvement was obtained and pericardial effusion did not appear thereafter. She died 4 months after the diagnosis of cardiac invasion. On autopsy myocardial invasion was identified. The pericardium widely adhered and effusion measured 42 ml.

Uterine sarcomas are relatively rare tumors that account for approximately 1-3% of female genital tract malignancies and between 4-9% of uterine cancers. Less than 8% of all cases are Mullerian adenosarcoma, a distinctive uterine neoplasm characterized by a benign, but occasionally atypical, epithelial and a malignant, usually low-grade, stromal component, both of which should be integral and neoplastic constituents of the tumor. Mullerian adenosarcoma with sarcomatous overgrowth (MASO) is a very aggressive variant, associated with post-operative recurrence, metastases, even when diagnosed in early stage. We present a fourth MASO case derived from uterine cervix in a 72-year-old woman with metrorrhagia and a polypoid mass protruding through the cervical ostium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, systematic pelvic lymph node dissection, omental biopsy and appendectomy were performed. Surgery treatment was associated with adjuvant whole-pelvis radiation (45 Gy) and adjuvant chemotherapy (cisplatin/ifosfamide). After nine months of follow up, the patient was free of tumor. The rarity of MASO of the cervix involves a management difficult. Most authors recommend total abdominal hysterectomy, usually accompanied by bilateral salpingo-oophorectomy. There is no common agreement on staging by lymphadenectomy during primary surgery and adjuvant chemo-radio therapy.

Drug selection, the key for chemotherapy, is one of the most difficult decision-making in clinic for the treatment of malignant tumors. How to choose is undetermined. Here a new strategy--predictive molecule-targeted chemotherapy (PMTC)--is put forward to choose relatively sensitive chemotherapeutic drugs and to avoid relatively resistant traditional drugs according to the expression of predictive molecules in individual tumor tissue. For example, paclitaxel is regarded as a relatively sensitive drug and may be chosen for the tumors with high expression of p53, while it is predicted as relatively resistant drug and should be avoided for the tumors with high expression of P-glycoprotein (P-gp). Here, we reviewed the predictive values of a variety of molecules, such as p53, P-gp, topoisomerase-1, topoisomerase-2, MSI, BRCA-1, ERCC1, FANC, hMHL1/2, XPD, Bcl-2, ErbB-2, MGMT, dihydropyridine dehydrogenase (DPD), thymidylate synthetase (TS), deoxycytidine kinase (dCK), Ras, Bax, Cyclin A, tubulin proteins, and so on, for the efficacy of some traditional chemotherapeutic drugs, such as platinum, oxaliplatin, cyclophosphamide, ifosfamide, dacarbazine, methotrexate, 5-flurouracil, gemcitabine, vincristine, vinorelbine, paclitaxel, etoposide, irinotecan, topotecan, and so on.

Ombrabulin (AVE8062) disrupts the vasculature of established tumours and has shown preclinical synergistic anti-tumour activity when combined with cisplatin. In this phase 3 trial, we aimed to assess the efficacy and safety of ombrabulin plus cisplatin compared with placebo plus cisplatin in patients with advanced soft-tissue sarcomas. We did this multinational, randomised, double-blind, placebo-controlled phase 3 study at 44 centres in ten countries. Patients aged 18 years and older with metastatic soft-tissue sarcomas, an Eastern Cooperative Oncology Group performance status of 0-2, and who had previously received treatment with anthracycline and ifosfamide were randomly assigned (1:1) to intravenous infusion of ombrabulin 25 mg/m(2) plus cisplatin 75 mg/m(2) or intravenous infusion of placebo plus cisplatin 75 mg/m(2) every 3 weeks. Patients were allocated to treatment using a permuted blocks randomisation scheme (block size of four) via an interactive voice-response system, and stratified by histological subtype. Patients, medical staff, study investigators, and individuals who handled and analysed the data were masked to treatment assignment. Our primary endpoint was median progression-free survival in the intention-to-treat population. Safety analyses were done on all randomised patients who received at least one dose of study drug. This trial is now closed, and is registered with ClinicalTrials.gov, number NCT00699517. Between June 13, 2008, and April 26, 2012, we randomly assigned 355 patients to ombrabulin plus cisplatin (n=176) or placebo plus cisplatin (n=179). Median duration of follow-up was 27·9 (IQR 20·9-33·2) in the placebo group and 30·5 months (20·7-37·6) in the ombrabulin group. Progression-free survival was slightly, but significantly, improved in the ombrabulin group compared with the placebo group (median 1·54 months [95% CI 1·45-2·69] vs 1·41 [1·38-1·58] months; hazard ratio 0·76 [95% CI 0·59-0·98]; p=0·0302). Grade 3 or 4 adverse events occurred more frequently in individuals in the ombrabulin group than in those in the placebo group and included neutropenia (34 [19%] in the ombrabulin group vs 14 [8%] in the placebo group) and thrombocytopenia (15 [8%] vs six [3%] for placebo). Adverse events leading to death occurred in 18 patients in the ombrabulin group and 10 patients in the placebo group. The combination of ombrabulin and cisplatin significantly improved progression-free survival; however, it did not show a sufficient clinical benefit in patients with advanced soft-tissue sarcomas to support its use as a therapeutic option. Predictive biomarkers are needed for the rational clinical development of tumour vascular-disrupting drugs for soft-tissue sarcomas. Sanofi. Copyright © 2015 Elsevier Ltd. All rights reserved.

The influence of oxazaphosphorines alkylating agents on autonomic nervous system activity in rat experimental cystitis model.

PubMed

Dobrek, Łukasz; Baranowska, Agnieszka; Thor, Piotr J

2013-01-01

The oxazaphosphorines alkylating agents (cyclophosphamide; CP and ifosfamide; IF) are often used in common clinical practice. However, treatment with CP/IF is burdened with the risk of many adverse drug reactions, especially including hemorrhagic cystitis (HC) that is associated with bladder overactivity symptoms (OAB). The HC pathophysiology is still not fully displayed; it seems that autonomic nervous system (ANS) functional abnormalities play important role in this disturbance. The aim of our study was to reveal the potential ANS differences in rat experimental HC model, evoked by CP and IF by an indirect ANS assessment--heart rate variability (HRV) study. We carried out our experimental research in three essential groups: control group (group 1), cyclophosphamide-induced HC (CP-HC; group 2) one and ifosfamide-induced HC (IF-HC; group 3) one. CP was i.p. administrated four times in dose of 75 mg/kg body weight while IF-treated rats received i.p. five drug doses; 50 mg/kg body weight. Control rats were administrated i.p. vehicle in appropriate volumes as CP/IF treated animals. HRV studies were performed the next day after the last oxazaphosphorines dose. Standard time- and spectral (frequency) domain parameters were estimated. We confirmed the HC development after both CP/IF in macroscopic assessment and bladder wet weight measurement; however, it was more aggravated in CP-HC group. Moreover, we demonstrated HRV disturbances, suggesting ANS impairment after both studied oxazaphosphorines, however, consistent with the findings mentioned above, the autonomic dysfunction was more emphasized after CP. CP treatment was also associated with changes of non-normalized HRV spectral components percentage distribution--a marked very low frequency--VLF [%] increase together with low frequency--LF [%] and high frequency--HF [%] decrease were observed. Taking into consideration the next findings, demonstrating the lack of both normalized power spectral components (nLF and nHF) values, the VLF percentage change seems to be of special meaning. IF produced smaller autonomic disturbances, and gentler bladders histological abnormalities comparing to CP. However, similar to CP, VLF [%] relative augmentation together with LF [%] and HF [%] drop accompanied the global ANS activity decrease. Additionally, in the case of IF treatment, a slight trend of nLF increase with nHF decrease was noted, suggesting the possible functional rearrangement between sympathetic (nLF) and parasympathetic (nHF) tension. It seems possible that the vagal withdrawal and--as a consequence--sympathetic overactivity, reflected by VLF [%] enlargement and HF and LF [%] diminishing (as well as LF and HF values decrease), may be an evidence of impaired anti-inflammatory cholinergic pathway, aggravating bladder inflammatory lesions. To sum up, our study showed ANS impairment in both CP- and IF-evoked experimental HC that was reflected in HRV recordings. HRV study, thus, may be considered to be a diagnostic tool for CP/IF treated patients, estimating autonomic abnormalities, associated with the HC development risk and its clinical course.

Due to the rarity and the variety of histological types of sinonasal cancers, there is a paucity of data regarding strategy for their optimal treatment. Generally, outcomes of advanced and higher grade tumors remain unsatisfactory, despite the employment of sophisticated surgical approaches, technical advances in radiation techniques and the use of heavy ion particles. In this context, we critically evaluated the role of systemic therapy as part of a multidisciplinary approach to locally advanced disease. Induction chemotherapy has shown encouraging activity and could have a role in the multimodal treatment of patients with advanced sinonasal tumors. For epithelial tumors, the most frequently employed chemotherapy is cisplatin, in combination with either 5-fluorouracil, taxane, ifosfamide, or vincristine. Only limited experiences with concurrent chemoradiation exist with sinonasal cancer. The role of systemic treatment for each histological type (intestinal-type adenocarcinoma, sinonasal undifferentiated carcinoma, sinonasal neuroendocrine carcinoma, olfactory neuroblastoma, sinonasal primary mucosal melanoma, sarcoma) is discussed. The treatment of SNC requires a multimodal approach. Employment of systemic therapy for locally advanced disease could result in better outcomes, and optimize the therapeutic armamentarium. Further studies are needed to precisely define the role of systemic therapy and identify the optimal sequencing for its administration in relation to local therapies. Copyright © 2015 Elsevier Ltd.

200 cancer patients who were due to receive fractionated chemotherapy (cisplatin greater than or equal to 15, ifosfamide greater than or equal to 1.2 or etoposide greater than or equal to 120, all mg/m2 per day) for 5 days, entered a multicentre study. Patients were randomised single-blind to receive either prophylactic intravenous granisetron (40 micrograms/kg) or alizapride (4 mg/kg followed by 4 mg/kg at 4 and 8 h post-treatment) plus dexamethasone 8 mg. Granistron was superior to the combination in preventing nausea and vomiting (54% vs. 43% complete responders). The differences were in the cisplatin-treated group. The time to first episode of moderate to severe nausea was significantly longer in the granisetron group (P = 0.03). Dosing with granisetron was more simple, with over 85% of patients requiring only a single prophylactic dose. Fewer patients receiving granisetron experienced adverse events (48% vs. 62%, P = 0.047). The frequency of constipation was, as expected, significantly higher in the granisetron group. Extrapyramidal effects, which were not noted by any granisetron patient, occurred in 5.3% of comparator patients.

Extravascular use of drug-eluting beads: A promising approach in compartment-based tumor therapy

Intraperitoneal carcinomatosis (PC) may occur with several tumor entities. The prognosis of patients suffering from PC is usually poor. Present treatment depends on the cancer entity and includes systemic chemotherapy, radiation therapy, hormonal therapy and surgical resection. Only few patients may also benefit from hyperthermic intraperitoneal chemotherapy with a complete tumor remission. These therapies are often accompanied by severe systemic side-effects. One approach to reduce side effects is to target chemotherapeutic agents to the tumor with carrier devices. Promising experimental results have been achieved using drug-eluting beads (DEBs). A series of in vitro and in vitro experiments has been conducted to determine the suitability of their extravascular use. These encapsulation devices were able to harbor CYP2B1 producing cells and to shield them from the hosts immune system when injected intratumorally. In this way ifosfamide - which is transformed into its active metabolites by CYP2B1 - could be successfully targeted into pancreatic tumor growths. Furthermore DEBs can be used to target chemotherapeutics into the abdominal cavity for treatment of PC. If CYP2B1 producing cells are proven to be save for usage in man and if local toxic effects of chemotherapeutics can be controlled, DEBs will become promising tools in compartment-based anticancer treatment.

The pineal anlage tumor is a very infrequent malign neoplasm. Even though it has been documented in literature, it is not listed yet in the World Health Organization's last nervous system classification (2007). It is a primitive pineal tumor with neuroepithelial and ectomesenchyme differentiation. Due to its low frequency, the understanding of its biological behavior and a suitable treatment are incomplete. In a search performed in PubMed with the term pineal anlage tumor, only seven informed cases were identified between 1989 and 2011. An 8-month-old infant was brought to medical attention because he had a progressive enlargement of the cephalic perimeter, and convergent strabismus of two months of evolution. A pineal tumor was identified. The histology showed glial tissue, ganglia cells, pigmented neuroepithelium and striate muscle cells. A ventriculoperitoneal derivation was done to diminish hydrocephalic pressure and also to led the complete surgical resection. The patient was treated with two courses of chemotherapy with carboplatine, ifosfamide and mesna. One year after the treatment, the patient is asymptomatic. This is the first case reported in Spanish language. Given that it is a really infrequent tumor, it could be misdiagnosed as teratome, melanotic or mesoblastic medulloblastoma, or a melanotic neuroectodermal tumor of childhood (melanotic prognoma).

Mediastinal germ cell tumours (M-GCT) are rare forms of neoplasms compared with other tumours of the same location. They are classified in seminomas, malignant non-seminomatous GCT and teratomas. The malignant transformation of the somatic component of the teratoma, with sarcomatous or carcinomatous degeneration, is even more uncommon. We report the clinical case of a 32 year old man who presented with severe chest pain on the right hemithorax. The image exams revealed the existence of a large heterogeneous lesion with a diameter of 7.7 cm, with areas of lipomatous density and a calcic image with the appearance of a tooth, in the right projection of the anterior mediastinum, in the vicinity of the large vessels, compatible with teratoma. The transthoracic biopsy (CT guided) showed morphologic aspects of sarcoma. The patient was operated on with the en bloc resection of the mediastinal mass, right lung, a segment of the pericardium and the thymus. The pathological studies showed a teratoma with malignant transformation of the mesenquimatous component, with muscular differentiation into leiomiosarcoma and rabdomiosarcoma. After surgery, the patient was treated with a scheme of doxorubicin and ifosfamide. The most prominent concepts related to this clinical entity, as well as its treatment, are debated in this article, based on the most recent publications dedicated to the subject.

To evaluate the activity and tolerability of dimethylsulfoxide (DMSO) in the prevention of soft tissue toxicity after extravasation of cytotoxic drugs. From June 1991 to December 1994, all patients who had an extravasation during intravenous (IV) infusion of cytotoxic drugs in our institution were considered for an open, prospective study of preventive treatment with 99% DMSO, applied topically on the extravasation site every 8 hours for 7 days. Intermittent local cooling (for 1 hour three times daily) on the first 3 days was also used. One hundred forty-four patients with extravasations of doxorubicin (n = 11), epirubicin (n = 46), mitomycin (n = 5), mitoxantrone (n = 13), cisplatin (n = 44), carboplatin (n = 6), ifosfamide (n = 14), and fluorouracil (n = 5) entered the study; 127 were assessable. Only one patient suffered an ulceration. The treatment was well tolerated, with mild local burning and a characteristic breath odor being the only side effects of DMSO application, even in cases in which treatment continued for up to 6 weeks to obtain remission of the symptoms of extravasation. Topical DMSO is an effective and safe antidote that may be used with local cooling after extravasations of vesicant drugs other than those drugs for which standard interventions are defined.

A 24-year-old man was referred to our hospital with a painless mass on the left side of his neck. Ultrasonography detected right testicular tumor and computerized tomography scanning revealed a left supraclavicular lymph node mass and bulky retroperitoneal lymph node mass. He initially underwent right high orchiectomy, combination chemotherapy and retroperitoneal lymph node dissection for advanced testicular non-seminomatous germ cell tumor. Six years later, late relapse was detected in the lung. After complete remission of the lung metastasis with chemotherapy, the serum alpha-fetoprotein began to increase because of superior vena caval thrombus extending into the right atrium. Emergency surgical excision was performed successfully using extracorporeal circulation to prevent pulmonary embolism and the resected specimen pathologically revealed adenocarcinoma interpreted as teratoma malignant transformation. Adjuvant chemotherapy consisting of paclitaxel, ifosfamide and nedaplatin were administered for subsequent slight elevation of serum F-human chorionic gonadotropin beta, resulting in successful normalization again. Later, he suddenly died of cerebral infarction without any evidence of recurrence 138 months after his initial presentation. We report herein an extremely uncommon case of advanced testicular germ cell tumor with development of superior vena caval thrombus extending into the right atrium.

Background: Most chemotherapeutic drugs are known to cause nephrotoxicity. Therefore, new strategies have been considered to prevent chemotherapy-induced nephrotoxicity. It is of note that Nigella sativa (NS), or its isolated compound Thymoquinone (TQ), has a potential role in combating chemotherapy-induced nephrotoxicity. AIM: To analyze and report the outcome of experimental animal studies on the protective effects of NS/TQ on chemotherapy-associated kidney complications. Design: Standard systematic review and narrative synthesis. Data Sources: MEDLINE, EMBASE databases were searched for relevant articles published up to March 2017. Additionally, a manual search was performed. Criteria for a study’s inclusion were: conducted in animals, systematic reviews and meta-analysis, containing data on nephroprotective effects of NS/TQ compared to a placebo or other substance. All strains and genders were included. Results: The database search yielded 71 studies, of which 12 (cisplatin-induced nephrotoxicity 8; methotrexate-induced nephrotoxicity 1; doxorubicin-induced nephrotoxicity 2; ifosfamide-induced nephrotoxicity 1) were included in this review. Conclusions: Experimental animal studies showed the protective effect of NS, or TQ, on chemotherapy-induced nephrotoxicity. These effects are caused by decreasing lipid peroxidation and increasing activity of antioxidant enzymes in renal tissue of chemotherapy-treated animals. PMID:28629150

Developing drugs to treat the toxic effects of lethal toxin (LT) and edema toxin (ET) produced by B. anthracis is of global interest . We utilized a computational approach to score 474 drugs/compounds for their ability to reverse the toxic effects of anthrax toxins. For each toxin or drug/compound, we constructed an activity network by using its differentially expressed genes, molecular targets, and protein interactions. Gene expression profiles of drugs were obtained from the Connectivity Map and those of anthrax toxins in human alveolar macrophages were obtained from the Gene Expression Omnibus. Drug rankings were based on the ability of a drug/compound's mode of action in the form of a signaling network to reverse the effects of anthrax toxins; literature reports were used to verify the top 10 and bottom 10 drugs/compounds identified. Simvastatin and bepridil with reported in vitro potency for protecting cells from LT and ET toxicities were computationally ranked fourth and eighth. The other top 10 drugs were fenofibrate, dihydroergotamine, cotinine, amantadine, mephenytoin, sotalol, ifosfamide, and mefloquine; literature mining revealed their potential protective effects from LT and ET toxicities. These drugs are worthy of investigation for their therapeutic benefits and might be used in combination with antibiotics for treating B. anthracis infection.

In patients with Ewing sarcoma and some distinct subgroups of soft tissue sarcoma (STS), a quantitatively sufficient autologous peripheral blood stem cell (PBSC) collection for stem cell support might facilitate treatment continuation, dose-intensification, and high-dose chemotherapy. Here, we provide a detailed evaluation of PBSC collection upon vincristine, ifosfamide, doxorubicin, and etoposide (VIDE) chemomobilization. Mobilization and collection parameters of 42 sarcoma patients (Ewing sarcoma n = 35, other STS n = 7) were analyzed retrospectively. Data were evaluated with regard to the number of previous VIDE therapy cycles. All patients reached the collection goal of ≥2.0 × 10 6 CD34 + cells/kg body weight (bw) upon VIDE/G-CSF mobilization, in the majority of cases with one single leukapheresis (LP) session (n = 29, 69%). No significant differences were identified with regard to mobilization and collection variables or the number of previous induction VIDE therapy cycles. However, upon 5 cycles of VIDE, we found the highest relative proportion of patients who required two or three LP sessions. Our data demonstrate the feasibility of successful PBSC collection upon VIDE chemomobilization even after up to five cycles of induction therapy, while at the same time the increasing risk of bone marrow exhaustion with every consecutive cycle is outlined. © 2017 John Wiley & Sons A/S.

Degradation of 40 selected pharmaceuticals by UV/H2O2.

The occurrence of pharmaceuticals in source waters is increasing. Although UV advanced oxidation is known to be an effective barrier against micropollutants, degradation rates are only available for limited amounts of pharmaceuticals. Therefore, the degradation of a large group of pharmaceuticals has been studied in this research for the UV/H2O2 process under different conditions, including pharmaceuticals of which the degradation by UV/H2O2 was never reported before (e.g., metformin, paroxetine, pindolol, sotalol, venlafaxine, etc.). Monochromatic low pressure (LP) and polychromatic medium pressure (MP) lamps were used for three different water matrices. In order to have well defined hydraulic conditions, all experiments were conducted in a collimated beam apparatus. Degradation rates for the pharmaceuticals were determined. For those compounds used in this research that are also reported in literature, measured degradation results are in good agreement with literature data. Pharmaceutical degradation for only photolysis with LP lamps is small, which is increased by using a MP lamp. Most of the pharmaceuticals are well removed when applying both UV (either LP or MP) and H2O2. However, differences in degradation rates between pharmaceuticals can be large. For example, ketoprofen, prednisolone, pindolol are very well removed by UV/H2O2, whereas metformin, cyclophosphamide, ifosfamide are very little removed by UV/H2O2. Copyright © 2013 Elsevier Ltd.

The kinetics of the ozone consumption for the pretreatment of hospital wastewater has been analysed in order to determine the reaction rate coefficients between the ozone and the readily oxidisabled organic matter and cytostatic compounds. The wastewater from a medium size hospital was treated with ozone and peroxone methodologies, varying the ozone concentration, the reaction time and the hydrogen peroxide doses. The analysis shows that there are four cytostatic compounds, i.e. irinotecan, ifosfamide, cyclophosphamide and capecitabine, detected in the wastewaters and they are completely removed with reasonably short times after the ozone treatment. Considering the reactor geometry, the gas hydrodynamics, the mass transfer of ozone from gas to liquid and the reaction of all oxidisable compounds of the wastewater it is possible to determine the chemical ozone demand, COzD, of the sample as 256mgO3L(-1) and the kinetic rate coefficient with the dissolved organic matter as 8.4M(-1)s(-1). The kinetic rate coefficient between the ozone and the cyclophosphamide is in the order of 34.7M(-1)s(-1) and higher for the other cytostatics. The direct economic cost of the treatment was evaluated considering this reaction kinetics and it is below 0.3€/m(3) under given circumstances. Copyright © 2016 Elsevier B.V. All rights reserved.

To evaluate the role of biochemical investigations (BI) and diagnostic tools (DT) in ADR detection. An observational prospective cross-sectional study was done using suspected ADR data collection form. A total of 2381 ADR related events were recorded in two years. Total number/percentage of biochemical abnormalities (BA) related ADR detection rate was 14.57% and of DT was 1.091% in contrast to 84.33% recorded with clinical presentation. Maximum cases were inward patients (87.13%), 67.02% were recorded by active surveillance. ADR detection rate at one point & detection on follow up was 56.31% Vs 46.38%. ADR detection rate of ECG, endoscopy, X-ray were 0.57%, 0.22%, 0.22% and of CT scan, MRI, DEXA scan, USG and biopsy was 0.04% each. Maximum ADRs were severe/serious, latent and Type-A in nature. Anemia (4.6%), followed by liver dysfunction (2.8%), renal dysfunction, electrolyte imbalance, hyperglycemia (1.1% each), abnormal coagulation profile (1%), decrease platelet count (0.8%), hypoglycemia (0.7%) were the most common BAs. Anti retroviral drugs (ART), tirofiban and methotrexate accounted for anemia, ART and anti tubercular drugs for liver & renal dysfunction, insulin for hypoglycemia, tirofiban, paclitaxel, capecipabine and ifosfamide for thrombocytopenia, hematuria by enoxaparin & dyslipidemia with ART were common ADRs. BI and DT can play very important role in ADR detection.

Ewing sarcoma has recently been reported to be sensitive to poly(ADP)-ribose polymerase (PARP) inhibitors. Searching for synergistic drug combinations, we tested several PARP inhibitors (talazoparib, niraparib, olaparib, veliparib) together with chemotherapeutics. Here, we report that PARP inhibitors synergize with temozolomide (TMZ) or SN-38 to induce apoptosis and also somewhat enhance the cytotoxicity of doxorubicin, etoposide, or ifosfamide, whereas actinomycin D and vincristine show little synergism. Furthermore, triple therapy of olaparib, TMZ, and SN-38 is significantly more effective compared with double or monotherapy. Mechanistic studies revealed that the mitochondrial pathway of apoptosis plays a critical role in mediating the synergy of PARP inhibition and TMZ. We show that subsequent to DNA damage-imposed checkpoint activation and G2 cell-cycle arrest, olaparib/TMZ cotreatment causes downregulation of the antiapoptotic protein MCL-1, followed by activation of the proapoptotic proteins BAX and BAK, mitochondrial outer membrane permeabilization (MOMP), activation of caspases, and caspase-dependent cell death. Overexpression of a nondegradable MCL-1 mutant or BCL-2, knockdown of NOXA or BAX and BAK, or the caspase inhibitor N-benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone (zVAD.fmk) all significantly reduce olaparib/TMZ-mediated apoptosis. These findings emphasize the role of PARP inhibitors for chemosensitization of Ewing sarcoma with important implications for further (pre)clinical studies. ©2015 American Association for Cancer Research.

Introduction Prostate embryonal rhabdomyosarcoma (ERMS) is a common tumour in infants and children, with a median occurrence age of 5 years, but it is rare in adults. It is characterized by a high degree of malignancy, both local rapid growth with formation of large pelvic masses, often leading to renal failure due to urethral obstruction, and systemic spread, commonly to the lungs, liver and bone. Several therapeutic approaches have been employed in the effort to treat prostate ERMS, but all of them have failed to gain a significant survival benefit in adult patients. Case report We report on a case of a stage IV prostate ERMS, approached with combined-modality treatment, with the administration of 5 courses of doxorubicin, ifosfamide and 2-mercaptoethane sulfonate sodium (mesna), and, subsequent radiotherapy to the prostatic bed (60 Gy/30 fxs). The patient remained free of progression of disease for about 1 year to finally experience a systemic relapse with multiple lung metastases and pleural effusion. The patient died for metastatic disease 27 months following the initial diagnosis. Conclusion While it remains questionable which therapeutic approach for prostate ERMS in adults is the most appropriate, our report demonstrates that a chemo-radiation combined treatment can control the prostate disease, reducing the symptoms and improving the quality of life of these patients, for the most part destined to die for systemic progression of disease.

Anti-angiogenesis target therapy for advanced osteosarcoma

Xie, Lu; Ji, Tao; Guo, Wei

2017-01-01

Osteosarcomas (OS), especially those with metastatic or unresectable disease, have limited treatment options. The greatest advancement in treatments occurred in the 1980s when multi-agent chemotherapy, including doxorubicin, cisplatin, high-dose methotrexate, and, in some regimens, ifosfamide, was demonstrated to improve overall survival compared with surgery alone. However, standard chemotherapeutic options have been limited by poor response rates in patients with relapsed or advanced cases. It has been reported that VEGFR expression correlates with the outcome of patients with osteosarcoma and circulating VEGF level has been associated with the development of lung metastasis. At present, it seems to us that progress has not been made since Grignani reported a phase II cohort trial of sorafenib and sorafenib combined with everolimus for advanced osteosarcoma, which, in a sense, have become a milestone as a second-line therapy for osteosarcoma. Although the recognization of muramyltripepetide phosphatidyl-ethanolamine has made some progress based on its combination with standard chemotherapy, its effect on refractory cases is controversial. Personalized comprehensive molecular profiling of high-risk osteosarcoma up to now has not changed the therapeutic prospect of advanced osteosarcoma significantly. Thus, how far have we moved forward and what therapeutic strategy should we prefer for anti-angiogenesis therapy? This review provides an overview of the most updated anti-angiogenesis therapy in OS and discusses some clinical options in order to maintain or even improve progression-free survival. PMID:28656259

A three-dimensional micro-scale perfusion-based two-chamber (3D-μPTC) tissue model system was developed to test the cytotoxicity of anticancer drugs in conjunction with liver metabolism. Liver cells with different cytochrome P450 (CYP) subtypes and glioblastoma multiforme (GBM) brain cancer cells were cultured in two separate chambers connected in tandem. Both chambers contained a 3D tissue engineering scaffold fabricated with biodegradable poly(lactic acid) (PLA) using a solvent-free approach. We used this model system to test the cytotoxicity of anticancer drugs, including temozolomide (TMZ) and ifosfamide (IFO). With the liver cells, TMZ showed a much lower toxicity to GBM cells under both 2D and 3D cell culture conditions. Comparing 2D, GBM cells cultured in 3D had much high viability under TMZ treatment. IFO was used to test the CYP-related metabolic effects. Cells with different expression levels of CYP3A4 differed dramatically in their ability to activate IFO, which led to strong metabolism-dependent cytotoxicity to GBM cells. These results demonstrate that our 3D-μPTC system could provide a more physiologically realistic in vitro environment than the current 2D monolayers for testing metabolism-dependent toxicity of anticancer drugs. It could therefore be used as an important platform for better prediction of drug dosing and schedule towards personalized medicine. PMID:22429982

2011-03-15

Zebrafish embryos have been shown to be a useful model for the detection of direct acting teratogens. This communication presents a protocol for a 3-day in vitro zebrafish embryo teratogenicity assay and describes results obtained for 10 proteratogens: 2-acetylaminofluorene, benzo[a]pyrene, aflatoxin B(1), carbamazepine, phenytoin, trimethadione, cyclophosphamide, ifosfamide, tegafur and thio-TEPA. The selection of the test substances accounts for differences in structure, origin, metabolism and water solubility. Apart from 2-acetylaminofluorene, which mainly produces lethal effects, all proteratogens tested were teratogenic in zebrafish embryos exposed for 3 days. The test substances and/or the substance class produced characteristic patterns of fingerprint endpoints. Several substances produced effects that could be identified already at 1 dpf (days post fertilization), whereas the effects of others could only be identified unambiguously after hatching at ≥ 3 dpf. The LC₅₀ and EC₅₀ values were used to calculate the teratogenicity index (TI) for the different substances, and the EC₂₀ values were related to human plasma concentrations. Results lead to the conclusion that zebrafish embryos are able to activate proteratogenic substances without addition of an exogenous metabolic activation system. Moreover, the teratogenic effects were observed at concentrations relevant to human exposure data. Along with other findings, our results indicate that zebrafish embryos are a useful alternative method for traditional teratogenicity testing with mammalian species.

The objective was to evaluate response rate, response duration, and toxicity after systemic and intraventricular chemotherapy in primary CNS lymphoma (PCNSL).
 From September 1995 to September 1998, 20 consecutive patients with PCNSL (median age 64, range 27 to 71 years) were enrolled in a pilot study evaluating chemotherapy without radiotherapy. A high dose methotrexate (MTX) (cycles 1, 2, 4, 5) and cytarabine (ara-C) (cycles 3, 6) based systemic therapy (including dexamethasone, vinca alkaloids, ifosfamide, and cyclophosphamide) was combined with intraventricular MTX, prednisolone, and ara-C.
 Complete response was achieved in 11 and partial remission in two patients; in one response could not be determined. Four patients showed progressive disease and two (70, 71 years) died from treatment related complications. Observation time was 2 to 59 months (median 31.5 months). Kaplan-Meier estimate for median time to treatment failure (TTF) was 20.5 months, and for median survival 54 months. Systemic toxicity was mainly hematological. Ommaya reservoir infection occurred in four patients and acute transient MTX induced encephalopathy in two (subacute in another). Cognitive dysfunction possibly due to treatment was seen in only one patient after relapse and after a total of 12 cycles (six at relapse).
 In conclusion, primary chemotherapy based on high dose MTX and ara-C is highly efficient in PCNSL. Toxicity is manageable in patients younger than 70years.

Background: Myxofibrosarcoma (MFS), formerly considered as a myxoid variant of malignant fibrous histiocytoma, is the most common sarcoma of the extremities in adults and is characterized by a high frequency of local recurrence. The clinical behavior of MFS is unpredictable and the efficacy of chemotherapy is still not well documented. Furthermore, given the relatively recent recognition of MFS as a distinct pathologic entity its cellular and molecular biology has still not been extensively studied in patient-derived preclinical models. We examined the molecular biology and treatment outcomes of high-grade, patient-derived MFS primary cultures. Methods: A total of three patient-derived MFS primary cultures were analyzed. We evaluated the role of CD109 expression and also looked for a correlation between transforming growth factor-beta (TGF-β) expression and sensitivity of the primary cultures to different drugs. Results: CD109 was a promising marker for the identification of more aggressive high-grade MFS and a potential therapeutic target. The results also highlighted the potential role of TGF-β in chemoresistance. Pharmacological analysis confirmed the sensitivity of the cultures to chemotherapy. The most active treatments were epirubicin alone and epirubicin in combination with ifosfamide, the latter representing the current standard of care for soft tissue sarcomas (STSs), including MFS. Conclusions: Our results provide a starting point for further research aimed at improving the management of MFS patients undergoing chemotherapy. PMID:29449896

In order to assess the true impact of each single enantiomer of pharmacologically active compounds (PACs) in the environment, highly efficient, fast and sensitive analytical methods are needed. For the first time this paper focuses on the use of ultrahigh performance supercritical fluid based chromatography coupled to a triple quadrupole mass spectrometer to develop multi-residue enantioselective methods for chiral PACs in environmental matrices. This technique exploits the advantages of supercritical fluid chromatography, ultrahigh performance liquid chromatography and mass spectrometry. Two coated modified 2.5 μm-polysaccharide-based chiral stationary phases were investigated: an amylose tris-3,5-dimethylphenylcarbamate column and a cellulose tris-3-chloro-4-methylphenylcarbamate column. The effect of different chromatographic variables on chiral recognition is highlighted. This novel approach resulted in the baseline resolution of 13 enantiomers PACs (aminorex, carprofen, chloramphenicol, 3-N-dechloroethylifosfamide, flurbiprofen, 2-hydroxyibuprofen, ifosfamide, imazalil, naproxen, ofloxacin, omeprazole, praziquantel and tetramisole) and partial resolution of 2 enantiomers PACs (ibuprofen and indoprofen) under fast-gradient conditions (<10 min analysis time). The overall performance of the methods was satisfactory. The applicability of the methods was tested on influent and effluent wastewater samples. To the best of our knowledge, this is the first feasibility study on the simultaneous separation of chemically diverse chiral PACs in environmental matrices using ultrahigh performance supercritical fluid based chromatography coupled with tandem mass spectrometry.

Non-target analysis has become an important tool in the field of water analysis since a broad variety of pollutants from different sources are released to the water cycle. For identification of compounds in such complex samples, liquid chromatography coupled to high resolution mass spectrometry are often used. The introduction of ion mobility spectrometry provides an additional separation dimension and allows determining collision cross sections (CCS) of the analytes as a further physicochemical constant supporting the identification. A CCS database with more than 500 standard substances including drug-like compounds and pesticides was used for CCS data base search in this work. A non-target analysis of a wastewater sample was initially performed with high performance liquid chromatography (HPLC) coupled to an ion mobility-quadrupole-time of flight mass spectrometer (IM-qTOF-MS). A database search including exact mass (±5 ppm) and CCS (±1 %) delivered 22 different compounds. Furthermore, the same sample was analyzed with a two-dimensional LC method, called LC+LC, developed in our group for the coupling to IM-qTOF-MS. This four dimensional separation platform revealed 53 different compounds, identified over exact mass and CCS, in the examined wastewater sample. It is demonstrated that the CCS database can also help to distinguish between isobaric structures exemplified for cyclophosphamide and ifosfamide.

Due to the current analytical processes that are not able to measure all the pharmaceutical molecules and to the high costs and the consumption of time to sample and analyze PhACs, models to calculate Predicted Environmental Concentrations (PECs) have been developed. However a comparison between MECs and PECs, taking into account the methods of calculations and peculiarly the parameters included in the calculation (consumption data, pharmacokinetic parameters, elimination rate in STPs and in the environment), is necessary to assess the validity of PECs. MEC variations of sixteen target PhACs [acetaminophen (ACE), amlodipine (AML), atenolol (ATE), caffeine (CAF), carbamazepine (CAR), doxycycline (DOX), epoxycarbamazepine (EPO), fluvoxamine (FLU), furosemide (FUR), hydrochlorothiazide (HYD), ifosfamide (IFO), losartan (LOS), pravastatin (PRA), progesterone (PROG), ramipril (RAM), trimetazidine (TRI)] have been evaluated during one hydrological cycle, from October 2011 to October 2012 and compared to PECs calculated by using an adaptation of the models proposed by Heberer and Feldmann (2005) and EMEA (2006). Comparison of PECs and MECS has been achieved for six molecules: ATE, CAR, DOX, FUR, HYD and PRA. DOX, FUR and HYD present differences between PECs and MECs on an annual basis but their temporal evolutions follow the same trends. PEC evaluation for these PhACs could then be possible but need some adjustments of consumption patterns, pharmacokinetic parameters and/or mechanisms of (bio)degradation. ATE, CAR and PRA are well modeled; PECs can then be used as reliable estimation of concentrations without any reserve. Copyright © 2014 Elsevier Ltd. All rights reserved.

Chemotherapy has cachectic effects, but it is unknown whether cytostatic agents alter skeletal muscle proteolysis. We hypothesized that chemotherapy-induced alterations in protein synthesis should result in the increased incidence of abnormal proteins, which in turn should stimulate ubiquitin-proteasome-dependent proteolysis. The effects of the nitrosourea cystemustine were investigated in skeletal muscles from both healthy and colon 26 adenocarcinoma-bearing mice, an appropriate model for testing the impact of cytostatic agents. Muscle wasting was seen in both groups of mice 4 days after a single cystemustine injection, and the drug further increased the loss of muscle proteins already apparent in tumor-bearing animals. Cystemustine cured the tumor-bearing mice with 100% efficacy. Surprisingly, within 11 days of treatment, rates of muscle proteolysis progressively decreased below basal levels observed in healthy control mice and contributed to the cessation of muscle wasting. Proteasome-dependent proteolysis was inhibited by mechanisms that include reduced mRNA levels for 20S and 26S proteasome subunits, decreased protein levels of 20S proteasome subunits and the S14 non-ATPase subunit of the 26S proteasome, and impaired chymotrypsin- and trypsin-like activities of the enzyme. A combination of cisplatin and ifosfamide, two drugs that are widely used in the treatment of cancer patients, also depressed the expression of proteasomal subunits in muscles from rats bearing the MatB adenocarcinoma below basal levels. Thus, a down-regulation of ubiquitin-proteasome-dependent proteolysis is observed with various cytostatic agents and contributes to reverse the chemotherapy-induced muscle wasting.

Purpose The objective of this study was to investigate the roles of the constitutive androstane receptor (CAR) in cyclophosphamide (CPA)- and ifosfamide (IFO)-mediated induction of hepatic drug-metabolizing enzymes (DME). Methods Induction of DMEs was evaluated using real-time RT-PCR and Western blotting analysis in human primary hepatocyte (HPH) cultures. Activation of CAR, pregnane X receptor (PXR), and aryl hydrocarbon receptor by CPA and IFO was assessed in cell-based reporter assays in HepG2 cells and/or nuclear translocation assays in HPHs. Results CYP2B6 reporter activity was significantly enhanced by CPA and IFO in HepG2 cells co-transfected with CYP2B6 reporter plasmid and a chemical-responsive human CAR variant (CAR1+A) construct. Real-time RT-PCR and Western blotting analysis in HPHs showed that both CPA and IFO induced the expressions of CYP2B6 and CYP3A4. Notably, treatment of HPHs with CPA but not IFO resulted in significant nuclear accumulation of CAR, which represents the initial step of CAR activation. Further studies in HPHs demonstrated that selective inhibition of PXR by sulforaphane preferentially repressed IFO- over CPA-mediated induction of CYP2B6. Conclusion These results provide novel insights into the differential roles of CAR in the regulation of CPA- and IFO-induced DME expression and potential drug-drug interactions. PMID:21487929

To evaluate response rate, event-free survival (EFS), and toxicity of two chemotherapeutic regimens for treatment of children younger than 36 months with malignant brain tumors and to estimate control intervals without irradiation in children with no residual tumor after initial surgery and induction chemotherapy and with delayed irradiation in patients with residual tumor or metastatic disease at diagnosis. Patients were randomly assigned to one of two regimens of induction chemotherapy (vincristine, cisplatin, cyclophosphamide, and etoposide v vincristine, carboplatin, ifosfamide, and etoposide). Maintenance chemotherapy began after induction in children without progressive disease. Children with no residual tumors after induction therapy and no metastatic disease at diagnosis were not to receive radiation therapy unless their tumors progressed. Two hundred ninety-nine infants were enrolled. Forty-two percent of patients responded to induction chemotherapy. At 5 years from study entry, the EFS rate was 27% +/- 3%, and the survival rate was 43% +/- 3%. There was no significant difference between the two arms in terms of response rate or EFS. For medulloblastoma, supratentorial primitive neuroectodermal tumor, ependymoma, and rhabdoid tumors, 5-year EFS rates were 32% +/- 5%, 17% +/- 6%, and 32% +/- 6%, and 14% +/- 7%, respectively. Fifty-eight percent of patients who were alive 5 years after study entry had not received radiation therapy. Intensified induction chemotherapy resulted in a high response rate of malignant brain tumors in infants. Survival was comparable to that of previous studies, and most patients who survived did not receive radiation therapy.

The external contamination and cross-contamination by cytotoxic drugs on the surface (outside and septum) of 133 vials from various manufacturers and available on the Swiss market were evaluated. All of the tested vials contained one of the following active ingredients: cyclophosphamide, cytarabine, doxorubicin, epirubicin, etoposide phosphate, gemcitabine, ifosfamide, irinotecan, methotrexate or vincristine. The validated wiping liquid chromatography-mass spectrometry method used in this study allowed for the simultaneous determination of these 10 cytotoxic drugs in less than 30 min. External contamination by cytotoxic drugs was detected on 63% of tested vials (outside and septum). The highest contamination level was observed on etoposide phosphate vials with 1896.66 ng of active ingredient on the outside of the vial. Approximately 20% of the contaminated vials had greater than 10 ng of cytotoxic drugs. Chemical contamination on the septum was detected on 38% of the vials. No contamination or very low levels of cytotoxic drugs, less than 1 ng per vial, were detected on the vials protected by plastic shrink-wrap. Traces of cytotoxic drugs different from the active ingredient were detected on 35% of the tested vials. Handling cytotoxic vials with gloves and having a procedure for the decontamination of vials are of the utmost importance for reducing exposure to cytotoxic drugs. Moreover, manufacturers must improve their procedures to provide products free from any contamination.

Suprasellar germinomas are rare intracranial neoplasms, which mainly occur in children and adolescents and manifest with endocrine symptoms and/or compression syndromes. The clinical, hormonal and morphological findings as well as treatment and complications were investigated in seven patients (six male, one female) with germinomas. Mean age at diagnosis was 19.7 years (range 15-32 years). First disease-related symptoms were diabetes insipidus (three patients), loss of libido (two patients), pseudopubertas praecox (one patient), and dwarfism (one patient). However, decisive symptoms leading to final diagnosis were visual disturbances (five patients), pubertas tarda (one patient), and hypogonadism (one patient). All patients were treated by transcranial radiation with a dose of 40-54 Gy. One patient received additional chemotherapy with cisplatin, etoposide, and ifosfamide (PEI). Patients were followed up for 14.6 years (range 7-27 years). Intracranial and pulmonary relapses were observed in two patients. Panhypopituitarism and diabetes insipidus were seen in all patients after treatment. Two patients suffered from loss of vision, two further patients from unilateral amaurosis. One patient developed epilepsy and persistent cognitive impairment. Long-term follow-up shows that two patients died from recurrent disease and decompensated liver cirrhosis, respectively. The other patients are long-term survivors. Full social integration with employment was possible in one case. Suprasellar germinomas cause endocrine symptoms during early tumor stages, however, diagnosis is generally established when ocular symptoms related to tumor compression are already present. Long-term survival is characterized by panhypopituitarism, diabetes insipidus and, partly, ocular or cerebral defects.

Pneumothorax as adverse event in patients with lung metastases of soft tissue sarcoma treated with pazopanib: a single reference centre case series.

Verschoor, Arie J; Gelderblom, Hans

2014-01-01

Recently, the phase III PALETTE study introduced pazopanib (Votrient®) as treatment for adult patients with locally advanced or metastatic non-liposarcoma soft tissue sarcoma after prior treatment with doxorubicin and/or ifosfamide. Pneumothorax was reported as adverse event in 8 of 246 treated patients (3.3%) in that study. This case series presents the incidence and clinic of this complication in the Leiden University Medical Centre. Forty-three patients were treated with pazopanib of which six patients (14.0%) developed a pneumothorax. These six patients were treated for malignant peripheral nerve sheath tumour, angiosarcoma, synovial sarcoma, fibromyxomatoid sarcoma, pleomorphic sarcoma and endometrial stromal sarcoma. All six patients had subpleural pulmonary or pleural metastases at the start of pazopanib and the pneumothorax developed during or shortly after treatment with pazopanib and was difficult to treat. The incidence reported by us is higher than the incidence in the PALETTE study. Trials with pazopanib in renal cell carcinoma, urothelial carcinoma and cervix carcinoma did not report pneumothorax as an adverse event, suggesting pneumothorax as a specific adverse event in soft tissue sarcoma patients treated with pazopanib. This may be related to the fact that there is often pleural metastatic involvement and cystic degeneration due to pazopanib treatment may add to the risk. The risk of an, often difficult to treat, pneumothorax during pazopanib therapy should be discussed with the patient before initiation of treatment for a pulmonary metastasized sarcoma and physicians should be alert to the occurrence of such an event.

To investigate the feasibility and efficacy of cyclophosphamide (CTX)-hydroxycamptothecin (HCPT) as second-line chemotherapy on advanced Ewing's sarcoma. From April 2009 to November 2010, 27 patients with advanced Ewing's sarcoma who had progressive disease after the first-line chemotherapy regimen of vincristine, dactinomycin and cyclophosphamide and ifosfamide and etoposide were retrospectively reviewed in this analysis. CTX was given (0.6 g/m(2), i.v. push day 1) and HCPT (6 mg/m(2), i.v. drip days 1-5) as second-line chemotherapy every 3 weeks. The primary end-point was overall response rate, the secondary end-point included progression-free, overall survival, disease control rate and toxicities. A total of 134 cycles were given, median four cycles per patient (range 2-6). Overall response rate was 30% and disease control rate was 82%, with two complete response (8%), six partial remission (22%) and 14 stable disease (52%). The median time to progression and overall survival time were 7 months (95% CI 3-10) and 11 months (95% CI 5-18), respectively. Major severe toxicities (grade 3 and 4) were: nausea/vomiting (17%), alopecia (17%); leukopenia (27%) in total cycles. Mild toxicities (grade 1 or 2) were leukopenia (73%), nausea/vomiting (83%), hepatic lesion (14%) and anemia (44%). A CTX-HCPT regimen can control disease progression effectively and the side effects can be tolerable for Chinese advanced Ewing's sarcoma patients. Further assessment is necessary to confirm the safety and efficacy of this treatment. © 2012 Wiley Publishing Asia Pty Ltd.

Chemotherapy for the treatment of malignant peripheral nerve sheath tumors in neurofibromatosis 1: a 10-year institutional review

PubMed Central

2013-01-01

Background Neurofibromatosis 1 (NF1) is the most common autosomal dominant disorder, with an incidence of 1 in 2,500-3,300 live births. NF1 is associated with significant morbidity and mortality because of complications, especially malignant peripheral nerve sheath tumors (MPNSTs), which mainly develop during adulthood. We evaluated our experience with management of NF1 with MPNSTs by standard chemotherapy with anthracycline and/or ifosfamide in terms of time to treatment failure and overall survival. Methods We performed a retrospective review of consecutive patients with NF1 and a diagnosis of MPNSTs between 1993 and 2003 in our referral center for NF1. Prognostic factors were evaluated by univariate analysis. Results We evaluated data for 21 patients with grade 1 (n=1), grade 2 (n=8) and grade 3 (n=12) MPNST; 16 presented localized disease and underwent surgery: margins for 6 were tumor-free (including 3 patients with amputation), 2 showed microscopic residual disease and 8 showed macroscopic residual disease. All patients received chemotherapy and 9 radiotherapy. Median time to treatment failure and overall survival were 7.8 and 17 months, respectively. Two patients were still alive at 138 and 167 months. We found no significant relationship between type of chemotherapy and time to treatment failure or overall survival. Conclusions MPNSTs are highly aggressive in NF1. Conventional chemotherapy does not seem to reduce mortality, and its role must be questioned. Recent advances in the molecular biology of MPNSTs may provide new prognostic factors and targeted therapies. PMID:23972085

Post-relapse survival (PRS) was evaluated in patients with Ewing sarcoma (EWS) enrolled in chemotherapy protocols based on the use of high-dose chemotherapy with busulfan and melfalan (HDT) as a first-line consolidation treatment in high-risk patients. EWS patients enrolled in ISG/SSG III and IV trials who relapsed after complete remission were included in the analysis. At recurrence, chemotherapy based on high-dose ifosfamide was foreseen, and patients who responded but had not received HDT underwent consolidation therapy with HDT. Data from 107 EWS patients were included in the analysis. Median time to recurrence (RFI) was 18 months, and 45 (42%) patients had multiple sites of recurrence. Patients who had previously been treated with HDT had a significantly (P = 0.02) shorter RFI and were less likely to achieve a second complete remission (CR2). CR2 status was achieved by 42 (39%) patients. Fifty patients received high-dose IFO (20 went to consolidation HDT). The 5-year PRS was 19% (95% CI 11 to 27%). With CR2, the 5-year PRS was 48% (95% CI 31 to 64%). Without CR2, median time to death was six months (range 1-45 months). According to the multivariate analysis, patients younger than 15 years, recurrence to the lung only, and RFI longer than 24 months significantly influenced the probability of PRS. Age, pattern of recurrence, RFI, and response to second-line chemotherapy influence post-relapse survival in patients with recurrent Ewing sarcoma. No survival advantage was observed from chemotherapy consolidation with HDT. © 2015 Wiley Periodicals, Inc.

In the present work, the development, optimization, and validation (including a whole stability study) of a fast, reliable, and comprehensive method for the analysis of ten anticancer drugs in hospital and urban wastewater is described. Extraction of these pharmaceutical compounds was performed using automated off-line solid-phase extraction followed by their determination by ultra-performance liquid chromatography coupled to a triple quadrupole-linear ion trap mass spectrometer. Target compounds include nine cytotoxic agents: cyclophosphamide, ifosfamide, docetaxel, paclitaxel, etoposide, vincristine, tamoxifen, methotrexate, and azathioprine; and the cytotoxic quinolone, ciprofloxacin. Method detection limits (MDL) ranged from 0.8 to 24 ng/L. Levels found of cytostatic agents in the hospital and wastewater influents did not differ significantly, and therefore, hospitals cannot be considered as the primary source of this type of contaminants. All the target compounds were detected in at least one of the influent samples analyzed: Ciprofloxacin, cyclophosphamide, tamoxifen, and azathioprine were found in most of them and achieving maximum levels of 14.725, 0.201, 0.133, and 0.188 μg/L, respectively. The rest of target cancer drugs were less frequently detected and at values ranging between MDL and 0.406 μg/L. Furthermore, a feasible, useful, and advantageous approach based on information acquisition tool (information-dependent acquisition) was used for the screening of human metabolites in hospital effluents, where the hydroxy tamoxifen, endoxifen, and carboxyphosphamide were detected.

Introduction Hodgkin's lymphoma is a highly curable disease. Autologous and reduced intensity allogeneic hematopoietic cell transplantations are alternatives to treat relapsed patients. Here, we report on the results of one service using these procedures. Methods All patients who underwent transplantations in our institution between 1996 and 2014 were retrospectively studied and demographics, toxicities and survival rate were analyzed. Results This study evaluated 24 autologous and five reduced intensity allogeneic transplantations: the median ages of the patients were 29 and 32 years, respectively. At the time of autologous transplantation, ten patients were in complete remission, nine had chemosensitive disease but were not in complete remission, three had refractory disease and the status of two is unknown. In the allogeneic group, two were in complete remission and three had chemosensitive disease. The 5-year overall survival after autologous transplantation was 42% (66% patients were in complete remission, 37% had chemosensitive disease with incomplete remission and 0% had refractory disease) and 1-year overall survival after allogeneic transplantation was 80%. Transplant-related mortality was 0% in patients conditioned with the ifosfamide/carboplatin/etoposide (ICE), carmustine/etoposide/cyclophosphamide (BEC) and carmustine/etoposide/cytarabine/melphalan (BEAM) regimens, 37% in patients conditioned with busulfan-based regimens and 20% in allogeneic transplantations. Conclusions Hematopoietic cell transplantation for relapsed Hodgkin's lymphoma is a potentially curative procedure especially in patients in complete remission at the time of autologous transplantations, and possibly after allogeneic transplantations. Further studies are necessary to clarify the role of allogeneic transplantations in the treatment of relapsed Hodgkin's lymphoma. PMID:26041421

Background We conducted a phase II clinical trial of induction chemotherapy followed by surgery ± radiotherapy for squamous cell carcinoma of the oral tongue (SCCOT) in young adults. Methods From September 2001 to October 2004, 23 patients aged 18–49 years with clinical T2-3N0-2M0 SCCOT and no prior radiotherapy, chemotherapy, or neck dissection underwent induction chemotherapy (paclitaxel, ifosfamide, and carboplatin) followed by glossectomy and neck dissection ± radiotherapy and chemotherapy. Results On final surgical pathology, 9 (39%) patients had a complete/major (2 complete) histologic response at the primary tumor site; 8 (35%) had no response or progression. Similarly, 9 (39%) patients had a complete response in the neck or remained node negative; 6 (26%) had an increase in nodal category. No treatment-associated deaths occurred, and toxicity was modest. At a median follow-up from the end of treatment of 52 months (minimum, 23 months), 10 (43%) patients developed recurrence, and all 10 died of cancer. Crude recurrence/cancer death rates were associated with ≤ a partial response at the tongue (P = .029), poor histologic differentiation (P = .012), and multiple adverse features on final surgical pathology (P = .040). Conclusions Response rates and overall survival with this induction chemotherapy regimen were limited, but complete/major response at the tongue was associated with excellent prognosis. Additionally, improved patient selection and predictive tumor biomarkers will be needed for induction chemotherapy to be routinely incorporated into the treatment of oral tongue cancer in young adults.

Acrolein (Acr) is a potent cytotoxic and DNA damaging agent which is ubiquitous in the environment and abundant in tobacco smoke. Acr is also an active cytotoxic metabolite of the anti-cancer drugs cyclophosphamide and ifosfamide. The mechanisms via which Acr exerts its anti-cancer activity and cytotoxicity are not clear. In this study, we found that Acr induces cytotoxicity and cell death in human cancer cells with different activities of p53. Acr preferentially binds nucleolar ribosomal DNA (rDNA) to form Acr-deoxyguanosine adducts, and induces oxidative damage to both rDNA and ribosomal RNA (rRNA). Acr triggers ribosomal stress responses, inhibits rRNA synthesis, reduces RNA polymerase I binding to the promoter of rRNA gene, disrupts nucleolar integrity, and impairs ribosome biogenesis and polysome formation. Acr causes an increase in MDM2 levels and phosphorylation of MDM2 in A549 and HeLa cells which are p53 active and p53 inactive, respectively. It enhances the binding of ribosomal protein RPL11 to MDM2 and reduces the binding of p53 and E2F-1 to MDM2 resulting in stabilization/activation of p53 in A549 cells and degradation of E2F-1 in A549 and HeLa cells. We propose that Acr induces ribosomal stress which leads to activation of MDM2 and RPL11-MDM2 binding, consequently, activates p53 and enhances E2F-1 degradation, and that taken together these two processes induce apoptosis and cell death.

Malignant transformation of mediastinal mature teratoma is extremely rare and worsens the prognosis of the disease. Transformation can appear synchronously to or several years after the initial diagnosis. Clinical and radiological signs can orientate the clinician but the definitive diagnosis is obtained thanks to histology. An 11 year-old boy presented with a mediastinal mature teratoma and bone and pulmonary metastases. He received six cycles of chemotherapy combining etoposide, ifosfamide, cisplatin, followed by resection of a 16×14×9cm mediastinal mass. Karyotype analysis revealed the presence of an additional sex chromosome X (47 XXY) pathognomonic of Klinefelter's syndrome. Ten years later, sciatalgia revealed malignant transformation of a pre-existing sacral bone metastasis into gastrointestinal adenocarcinoma. The patient received four cycles of chemotherapy combining oxaliplatin, 5-fluorouracil and cetuximab. This treatment was followed by a complete resection of the sacral metastasis and completed with adjuvant irradiation of 54Gy in 30 daily fractions. Twelve months after the diagnosis of relapse, the patient remained alive without disease. To our knowledge, this is the first case of adenocarcinoma developed in bone metastases of a mediastinal mature teratoma in a boy with a Klinefelter's syndrome. We propose a review of the literature and an analysis of 20 others published cases of mediastinal teratoma with malignant transformation into adenocarcinoma.

The combination of topotecan and cyclophosphamide is active in relapsed Ewing sarcoma family of tumors (ESFT). The feasibility of adding these agents combined with vincristine (vincristine-topotecan-cyclophosphamide [VTc]) to standard five-drug chemotherapy with vincristine-doxorubicin-cyclophosphamide (VDC) and ifosfamide-etoposide (IE) administered in an interval-compressed (2-week instead of 3-week intervals) schedule was investigated. Newly diagnosed patients with localized ESFT < 31 years, with good performance status and adequate organ function were eligible. Seventeen alternating cycles of chemotherapy with VTc, VDC, and IE were administered at 2-week intervals. Local control (LC) of the primary tumor occurred following six cycles. Primary endpoints were the ability to deliver chemotherapy in an interval-compressed schedule, and the rate of grade 3 or greater nonhematologic toxicity and grade 4 hematologic toxicity, which delayed chemotherapy by ≥2 weeks. Secondary endpoints were event-free survival (EFS) and overall survival (OS). Thirty-five patients with a median age of 11 years were enrolled. The mean time to last dose of chemotherapy prior to LC was 12.6 ± 1.4 weeks and 45.5% of patients received intended chemotherapy without any delay prior to LC. There were no toxic deaths or unexpected toxicities. Five-year EFS was 79.6% (95% confidence interval [CI]: 61.8-89.7%) and 5-year OS was 88% (95% CI: 71.4-95.3%). The addition of VTc to standard therapy was tolerable with sufficient interval compression compared to historical standard 3-week cycles. © 2015 Wiley Periodicals, Inc.

This paper describes a novel wipe sampling and high-performance liquid chromatography/tandem mass spectrometry (HPLC-MS/MS) method capable of simultaneously detecting 10 antineoplastic drugs (5-fluorouracil, oxaliplatin, methotrexate, vindesine, ifosfamide, cyclophosphamide, vincristine, vinblastine, docetaxel, and paclitaxel). The good overall recoveries and sensitivity values of this method along with the comparatively short run time (8 min) allows for its use in routine monitoring in health care facilities. The long-term behavior of the studied drugs on contaminated surfaces and the effect of surface roughness on drug recoveries were studied to gain insights about how these environmental variables influence the detection, cleaning, and occupational exposure of these drugs. Surfaces with higher roughness parameter (Ra) values (rougher) had the lowest recoveries while those with lower Ra (smoother) presented the highest recoveries. Long-term assessments evidence distinctive drug behaviors with oxaliplatin, vindesine, vincristine, and vinblastine being the less persistent drugs (~20% was recovered after 24 h) and docetaxel and paclitaxel the most persistent drugs with recoveries of 40% and 80% after 1 month. This information indicates the importance of collecting ancillary information about drug usage (throughput, timing, cleaning procedures, etc.) to interpret the results in the context of potential exposure. Finally, the method was successfully applied to evaluate trace surface contamination down to the single picogram per square centimeter in multiple work areas within three local health care centers on Vancouver Island, Canada. © The Author 2017.

The correct clinical staging of soft tissue sarcomas (STS) is critical for the selection of treatments. The staging system consists of histological grade of the tumors and French Federation of Cancer Center (FNCLCC) system based on mitotic count is widely used for the grading. In this study, we compared the validity and usefulness of Ki-67 grading system with FNCLCC system in JCOG0304 trial which investigated the efficacy and safety of perioperative chemotherapy with doxorubicin and ifosfamide for STS. All 70 eligible patients with STS in the extremities treated by perioperative chemotherapy in JCOG0304 were analyzed. Univariate and multivariate Cox regression analyses were conducted to investigate an influence on overall survival. The reproducibility of Ki-67 grading system in the histological grading of STS was higher than FNCLCC system (κ = 0.54 [95 % CI 0.39-0.71], and 0.46 [0.32-0.62], respectively). Although FNCLCC grade was not associated with overall survival (OS) in univariate analysis (HR 2.80 [0.74-10.55], p = 0.13), Ki-67 grading system had a tendency to associate with OS in univariate analysis (HR 4.12 [0.89-19.09], p = 0.07) and multivariate analysis with backward elimination (HR 3.51 [0.75-16.36], p = 0.11). This is the first report demonstrating the efficacy of Ki-67 grading system for the patients with STS in the prospective trial. The results indicate that Ki-67 grading system might be useful for the evaluation of histological grade of STS.

Bladder cancer.

Bladder cancer is a common and chemotherapy-responsive tumor, related to tobacco smoking, environmental arsenic exposure, industrial dye exposure, and parasitic schistosomiasis exposure. Both reduction of carcinogen exposure and chemoprevention, possibly with cyclooxygenase 2 inhibitors, should reduce the incidence. The search for the ideal screening and monitoring test continues with some promising new candidates, including survivin. Although 10-year survival can be achieved in 87% of early-stage patients with muscle-invasive disease rendered T(0) and 57% of those rendered T(1) at second look after transurethral resection bladder tumor, most still require radical cystectomy. Continued improvements in surgical techniques permit gains in quality of life after the procedure. Ten-year survival can still be achieved with cystectomy in the face of grossly positive lymph nodes in 32% of T(2) and 10% of T(3) patients. A recent meta-analysis indicates that preoperative irradiation is unlikely to be beneficial, but definitive chemoradiation can produce significant 5-year survival rates in nonoperative candidates and those desiring bladder preservation. The Intergroup now has preliminary data from a Southwest Oncology Group-based trial showing a significant benefit for neoadjuvant methotrexate, vinblastine, doxorubicin, and cisplatin. The regimen of gemcitabine and cisplatin is equally efficacious with less toxicity than methotrexate, vinblastine, doxorubicin, and cisplatin. It has been adopted as the standard arm in a phase III trial for advanced bladder cancer, comparing it with the triplet of gemcitabine, paclitaxel, and cisplatin. Other active agents in bladder cancer include ifosfamide, carboplatin, docetaxel, and vinorelbine, and various doublets of these agents are being tested in phase II trials, with promising results.

Background Attempts to improve survival outcomes of patients with high risk Ewing's sarcoma (ES) have focused on chemotherapy dose intensification strategies. Aim The objective of this study is to retrospectively evaluate clinical characteristics and outcome of pediatric patients with high risk ES treated at a single institution. Materials and methods From 1995 to 2008, seventeen patients (male:female, 14:3) were treated with dose-intensive therapy in our institution. Median age at diagnosis was 10 years (range: 2–15). Seven patients had metastases at diagnosis (lung in 6 cases and bone in one case). Eleven patients presented with unresectable disease. Fifteen (88.2%) received the Spanish Society of Pediatric Oncology protocol which includes six cycles of vincristine, doxorubicin, ifosfamide and etoposide. Two out of the six cases that were resectable received postoperative radiation. In addition, eleven patients received definitive radiation therapy. Finally, twelve (70.5%) out of 17 patients received myeloablative therapy with melphalan/etoposide. The rest of patients (N = 5) received busulfan/melphalan. Results Median follow-up was 78 months (range: 15–155 months). Initial responses were complete in all patients, but 9 of them developed progression disease. Seven patients became long-term event-free survivors. No patient died of toxicity after transplantation. The 2- and 5-year overall survival rates for all patients were 93% and 73%, respectively. Event-free survival rates were 74% and 54% at 2 and 5 years, respectively. Conclusion This single-institution experience suggests that myeloablative therapy against high risk ES is effective and safe. PMID:24376974

Primary Tumor Necrosis Predicts Distant Control in Locally Advanced Soft-Tissue Sarcomas After Preoperative Concurrent Chemoradiotherapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

MacDermed, Dhara M.; Miller, Luke L.; Peabody, Terrance D.

Purpose: Various neoadjuvant approaches have been evaluated for the treatment of locally advanced soft-tissue sarcomas. This retrospective study describes a uniquely modified version of the Eilber regimen developed at the University of Chicago. Methods and Materials: We treated 34 patients (28 Stage III and 6 Stage IV) with locally advanced soft-tissue sarcomas of an extremity between 1995 and 2008. All patients received preoperative therapy including ifosfamide (2.5 g/m2 per day for 5 days) with concurrent radiation (28 Gy in 3.5-Gy daily fractions), sandwiched between various chemotherapy regimens. Postoperatively, 47% received further adjuvant chemotherapy. Results: Most tumors (94%) were Grade 3,more » and all were T2b, with a median size of 10.3 cm. Wide excision was performed in 29 patients (85%), and 5 required amputation. Of the resected tumor specimens, 50% exhibited high (>=90%) treatment-induced necrosis and 11.8% had a complete pathologic response. Surgical margins were negative in all patients. The 5-year survival rate was 42.3% for all patients and 45.2% for Stage III patients. For limb-preservation patients, the 5-year local control rate was 89.0% and reoperation was required for wound complications in 17.2%. The 5-year freedom-from-distant metastasis rate was 53.4% (Stage IV patients excluded), and freedom from distant metastasis was superior if treatment-induced tumor necrosis was 90% or greater (84.6% vs. 19.9%, p = 0.02). Conclusions: This well-tolerated concurrent chemoradiotherapy approach yields excellent rates of limb preservation and local control. The resulting treatment-induced necrosis rates are predictive of subsequent metastatic risk, and this information may provide an opportunity to guide postoperative systemic therapies.« less

Occupational exposure to cytotoxic drugs in two UK oncology wards

Ziegler, E; Mason, H; Baxter, P

2002-01-01

Aims: To investigate the potential exposure to cytotoxic drugs of staff on two oncology wards in a large district, UK hospital under normal working conditions. Methods: Cytotoxic drug exposure was monitored in urine samples, surface wipes, and on disposable gloves by using a number of commonly used marker drugs, namely cyclophosphamide, ifosfamide, methotrexate, and the platino coordinated drugs. Questionnaire data on their work practices, potential exposure, use of protective personal equipment, and relevant training were collected from nursing, domestic, and clerical staff on two oncology wards. Results: The majority of staff were female with a mean age of 31 years. Roughly half of the staff studied were specifically trained nurses with an average of 3.5 years experience of administering cytotoxic drugs. No cytotoxic drug preparation or reconstitution was carried out on the wards. Disposable gloves, plastic armlets and aprons, but not eye protection, were invariably worn where there was potential exposure to cytotoxics. No cytotoxic drug was detected in any of the staff's urine samples. Isolated disposable latex gloves from nurses administering drugs showed some contamination, as did some surfaces within the wards' sluice rooms, but not in the ward areas where the drugs were stored and checked prior to administration. Conclusions: The risk management strategies in place, including use of personal protective equipment, staff training, and other organisational measures, have ensured that internal exposure is lower than the detection limits for the current biological monitoring methods. Levels of contamination appear significantly lower than earlier, non-UK published studies where different risk management strategies were in place and, in particular, ward staff may have been involved in some degree of cytotoxic drug reconstitution.

Patients with metastatic osteosarcoma at diagnosis or axial primary tumors have a poor prognosis. The aim of the study was to evaluate the feasibility and efficacy of intensified treatment with high-dose chemotherapy (HDCT) and stem cell rescue in this group. From May 1996 to August 2004, 71 patients were included in a Scandinavian-Italian single arm phase II study. Preoperative chemotherapy included methotrexate, doxorubicin, cisplatin and ifosfamide, and postoperative treatment consisted of two cycles of doxorubicin, one cycle of cyclophosphamide and etoposide and two courses of high-dose etoposide and carboplatin with stem cell rescue. Twenty-nine patients (43%) received two courses and 10 patients (15%) received one course of HDCT. HDCT was associated with significant toxicity, but no treatment-related deaths were recorded. Fourteen patients (20%) had disease progression before completion of the study protocol, and only 29/71 patients (41%) received the full planned treatment. Median event-free survival (EFS) was 18 months, and estimated 5-year EFS was 27%. Median overall survival (OS) was 34 months, and estimated 5-year OS was 31%. When patients who did not receive HDCT due to disease progression were excluded, there was no difference in EFS (P = 0.72) or OS (P = 0.49) between patients who did or did not receive HDCT. The administration of high-dose chemotherapy with stem cell rescue was feasible, but associated with significant toxicity. Patient outcome seemed comparable to previous studies using conventional chemotherapy. We conclude that HDCT with carboplatin and etoposide should not be further explored as a treatment strategy in high-risk osteosarcoma. © 2013 Wiley Periodicals, Inc.

To compare the survival benefit obtained with cisplatin plus gemcitabine, a cisplatin-based triplet, and nonplatinum sequential doublets in advanced non-small-cell lung cancer (NSCLC). Stage IIIB to IV NSCLC patients were randomly assigned to receive cisplatin 100 mg/m2 day 1 plus gemcitabine 1,250 mg/m2 days 1 and 8, every 3 weeks for six cycles (CG); cisplatin 100 mg/m2 day 1 plus gemcitabine 1,000 mg/m2 and vinorelbine 25 mg/m2 days 1 and 8, every 3 weeks for six cycles (CGV); or gemcitabine 1,000 mg/m2 plus vinorelbine 30 mg/m2 days 1 and 8, every 3 weeks for three cycles, followed by vinorelbine 30 mg/m2 days 1 and 8 plus ifosfamide 3 g/m2 day 1, every 3 weeks for three cycles (GV-VI). Five hundred fifty-seven patients were assigned to treatment (182 CG, 188 CGV, 187 GV-VI). Response rates were significantly inferior for the nonplatinum sequential doublet (CG, 42%; CGV, 41%; GV-VI, 27%; CG v GV-VI, P =.003). No differences in median survival or time to progression were observed. Toxicity was higher for the triplet: grade 3 to 4 neutropenia (GC, 32%; CGV, 57%; GV-VI, 27%; P <.05); neutropenic fever (CG, 4%; CGV, 19%; GV-VI, 5%; P <.0001); grade 3 to 4 thrombocytopenia (CG, 19%; CGV, 23%; GV-VI, 3%; P =.0001); and grade 3 to 4 emesis (GC, 22%; GCV, 32%; GV-VI, 6%; P <.0001). On the basis of these results, CG remains a standard regimen for first-line treatment of advanced NSCLC.

Background The objective of this randomized, prospective and controlled study was to investigate the ability of a closed-system transfer device (CSTD; BD-Phaseal) to reduce the occupational exposure of two isolators to 10 cytotoxic drugs and compare to standard compounding devices. Methods and Findings The 6-month study started with the opening of a new compounding unit. Two isolators were set up with 2 workstations each, one to compound with standard devices (needles and spikes) and the other using the Phaseal system. Drugs were alternatively compounded in each isolator. Sampling involved wiping three surfaces (gloves, window, worktop), before and after a cleaning process. Exposure to ten antineoplastic drugs (cyclophosphamide, ifosfamide, dacarbazine, 5-FU, methotrexate, gemcitabine, cytarabine, irinotecan, doxorubicine and ganciclovir) was assessed on wipes by LC-MS/MS analysis. Contamination rates were compared using a Chi2 test and drug amounts by a Mann-Whitney test. Significance was defined for p<0.05. Overall contamination was lower in the “Phaseal” isolator than in the “Standard” isolator (12.24% vs. 26.39%; p < 0.0001) although it differed according to drug. Indeed, the contamination rates of gemcitabine were 49.3 and 43.4% (NS) for the Standard and Phaseal isolators, respectively, whereas for ganciclovir, they were 54.2 and 2.8% (p<0.0001). Gemcitabine amounts were 220.6 and 283.6 ng for the Standard and Phaseal isolators (NS), and ganciclovir amounts were 179.9 and 2.4 ng (p<0.0001). Conclusion This study confirms that using a CSTD may significantly decrease the chemical contamination of barrier isolators compared to standard devices for some drugs, although it does not eliminate contamination totally.

High-dose chemotherapy with tandem or triple carboplatin and etoposide course is currently the first curative choice for relapsing GCT. The collection of an adequate amount of hematopoietic (CD34(+)) stem cells is a priority. We analyzed data of patients who underwent HDCT at 2 referral institutions. Chemotherapy followed by myeloid growth factors was applied in all cases. Uni- and multivariable models were used to evaluate the association between 2 prespecified variables and mobilization parameters. Analyses included only the first mobilizing course of chemotherapy and mobilization failures. A total of 116 consecutive patients underwent a mobilization attempt from December 1995 to November 2012. Mobilizing regimens included cyclophosphamide (CTX) 7 gr/m(2) (n = 39), cisplatin, etoposide, and ifosfamide (PEI) (n = 42), paclitaxel, cisplatin, and gemcitabine (TPG) (n = 11), and mixed regimens (n = 24). Thirty-seven percent were treated in first-line, 50% (n = 58) in second-line, 9.5% (n = 11) and 3.4% (n = 4) in third- and fourth-line settings, respectively. Six patients did not undergo HDCT because they were poor mobilizers, 2 in first- and second-line (1.9%), and 4 beyond the second-line (26.7%). In the multivariable model, third-line or later setting was associated with a lower CD34(+) cell peak/μL (P = .028) and a lower total CD34(+)/kg collected (P = .008). The latter was also influenced by the type of mobilizing regimen (P < .001). A decline in significant mobilization parameters was found, primarily depending on the pretreatment load. Results lend support to the role of CD34(+) cell mobilization in the therapeutic algorithm of relapsing GCT, for whom multiple HDCT courses are still an option, and potentially a cure.

Samples of influent (untreated) and effluent (treated) from 18 sewage treatment plants (STPs) in 14 municipalities in Canada were analyzed for residues of selected prescription and nonprescription drugs. Several neutral and acidic drugs were detected in effluents, including analgesic/anti-inflammatory agents, lipid regulators, and an antiepileptic drug, carbamazepine. Residues were extracted from effluents by solid-phase extraction, followed by either methylation and analysis of acidic drugs by gas chromatography/mass spectrometry or direct analysis of neutral drugs by liquid chromatography/tandem mass spectrometry. Analgesic/anti-inflammatory drugs such as ibuprofen and naproxen, as well as the metabolite of acetylsalicyclic acid, salicylic acid, were often detected in final effluents at microg/L concentrations. The acidic lipid regulator, clofibric acid, and the analgesic/anti-inflammatory drug diclofenac were not detected in any final effluent samples, which is not consistent with data from Europe. The precursor to clofibric acid, clofibrate, is not widely prescribed as a lipid regulator in Canada. However, the lipid regulators bezafibrate and gemfibrozil were detected in some samples of influent and effluent. The chemotherapy drugs ifosfamide and cyclophosphamide and the anti-inflammatory phenazone were not detected in influent or effluent samples, but the vasodilator drug pentoxyfylline was detected at ng/L concentrations in some final effluents. The widespread occurrence of carbamazepine at concentrations as high as 2.3 microg/L may be explained by use of this drug for other therapeutic purposes besides treatment of epilepsy and its resistance to elimination in STPs. The rates of elimination of ibuprofen and naproxen appeared to be elevated in STPs with hydraulic retention times for sewage greater than 12 h.

Untargeted metabolomics has the potential to improve the predictivity of in vitro toxicity models and therefore may aid the replacement of expensive and laborious animal models. Here we describe a long term repeat dose nephrotoxicity study conducted on the human renal proximal tubular epithelial cell line, RPTEC/TERT1, treated with 10 and 35 μmol·liter−1 of chloroacetaldehyde, a metabolite of the anti-cancer drug ifosfamide. Our study outlines the establishment of an automated and easy to use untargeted metabolomics workflow for HPLC-high resolution mass spectrometry data. Automated data analysis workflows based on open source software (OpenMS, KNIME) enabled a comprehensive and reproducible analysis of the complex and voluminous metabolomics data produced by the profiling approach. Time- and concentration-dependent responses were clearly evident in the metabolomic profiles. To obtain a more comprehensive picture of the mode of action, transcriptomics and proteomics data were also integrated. For toxicity profiling of chloroacetaldehyde, 428 and 317 metabolite features were detectable in positive and negative modes, respectively, after stringent removal of chemical noise and unstable signals. Changes upon treatment were explored using principal component analysis, and statistically significant differences were identified using linear models for microarray assays. The analysis revealed toxic effects only for the treatment with 35 μmol·liter−1 for 3 and 14 days. The most regulated metabolites were glutathione and metabolites related to the oxidative stress response of the cells. These findings are corroborated by proteomics and transcriptomics data, which show, among other things, an activation of the Nrf2 and ATF4 pathways. PMID:26055719

To investigate the dose intensity of induction chemotherapy and oncological outcomes of metastatic testicular cancer under centralized management through a regional medical network. We retrospectively analyzed the outcomes of 86 metastatic testicular cancer patients who were given induction chemotherapy at Tsukuba University Hospital and four branch hospitals between January 2000 and November 2010. Principally, management of patients with poor-prognosis disease and patients having risk factors for bleomycin, etoposide and cisplatin were referred to Tsukuba University Hospital before chemotherapy. For high-risk groups, etoposide and cisplatin or etoposide, ifosfamide and cisplatin was used as an alternative to bleomycin, etoposide and cisplatin. Overall, 56 and 30 patients were treated at Tsukuba University Hospital and branch hospitals, respectively. Forty-seven, 18 and 21 patients were classified with good-, intermediate- and poor-prognosis disease, respectively, according to the International Germ Cell Cancer Collaborative Group criteria. Eighteen of the 21 patients (86%) with poor-prognosis disease were treated at Tsukuba University Hospital from the beginning of induction chemotherapy. Induction chemotherapy with a high relative dose intensity was possible in most patients. The average relative dose intensity of each drug was >0.96. Treatment procedures other than induction chemotherapy were efficiently centralized; 74% of post-chemotherapy surgery and all second-line or subsequent chemotherapies were performed at Tsukuba University Hospital. The 5-year overall survival rates of the good-, intermediate- and poor-prognosis groups were 97, 93 and 84%, respectively. Induction chemotherapy with high relative dose intensity, post-chemotherapy surgery and salvage chemotherapy was accomplished efficiently through centralization of management. Oncological outcomes were excellent, especially in patients with poor-prognosis disease, whose 5-year OS reached 84%.

There is a paucity of literature reporting the outcome of intracranial sarcomas (IS) in children, adolescents, and young adults (CAYA). A multimodal therapeutic approach is commonly used, with no well-established treatment consensus. We conducted a retrospective review of CAYA with IS, treated at our institution, to determine their clinical findings, treatments, and outcomes. Immunohistochemistry (PDGFRA and EGFR) and DNA sequencing were performed on 5 tumor samples. A literature review of IS was also conducted. We reviewed 13 patients (median age, 7 years) with a primary diagnosis of IS between 1990 and 2015. Diagnoses included unclassified sarcoma (n = 9), chondrosarcoma (n = 2), and rhabdomyosarcoma (n = 2). Five patients underwent upfront gross total resection (GTR) of the tumor. The 5-drug regimen (vincristine, doxorubicin, cyclophosphamide, etoposide, and ifosfamide) was the most common treatment used. Nine patients died due to progression or recurrence (n = 8) or secondary malignancy (n = 1). The median follow-up period of the 4 surviving patients was 1.69 years (range 1.44-5.17 years). The 5-year progression-free survival and overall survival rates were 21 and 44 %, respectively. BRAF, TP53, KRAS, KIT, ERBB2, MET, RET, ATM, and EGFR mutations were detected in 4 of the 5 tissue samples. All 5 samples were immunopositive for PDGFRA, and only 2 were positive for EGFR. IS remain a therapeutic challenge due to high progression and recurrence rates. Collaborative multi-institutional studies are warranted to delineate a treatment consensus and investigate tumor biology to improve the disease outcome.

Purpose: Evaluate treatment and outcome of 20 patients with radioinduced osteosarcoma (RIO). Because of previous primary tumor treatment, RIO protocols were different from others we used for non-RIO. Patients and Methods: Between 1983 and 1998, we treated 20 RIO patients, ages 4-36 years (mean 16 years), with chemotherapy (two cycles before surgery, three postoperatively). The first preoperative cycle consisted of high-dose Methotrexate (HDMTX)/Cisplatinum (CDP)/Adriamycin (ADM) and the second of HDMTX/CDP/Ifosfamide (IFO). The three postoperative treatments were performed with cycles of MTX/CDP; IFO was used as single agent per cycle repeated three times. Results: Two patients received palliative treatment because theirmore » osteosarcoma remained unresectable after preoperative chemotherapy. The remaining 18 patients had surgery (7 amputations, 11 resections); histologic response to preoperative chemotherapy was good in 8 patients, poor in 10. At a mean follow-up of 11 years (range, 7-22 years), 9 patients remained continuously disease-free, 10 died from osteosarcoma and 1 died from a third neoplasm (myeloid acute leukemia). These results are not significantly different from those achieved in 754 patients with conventional osteosarcoma treated in the same period with protocols used for conventional treatment. However, this later group had an 18% 3-year event-free survival after treatment of relapse vs. 0% in the RIO group. Conclusion: Treated with neoadjuvant chemotherapy RIO seem to have an outcome that is not significantly different from that of comparable patients with conventional primary high grade osteosarcoma (5-year event-free survival: 40% vs. 60%, p = NS; 5-year overall survival 40% vs. 67%, p < 0.00008.« less

Background Cyclophosphamide, an alkylating agent, is widely used for the treatment of many adult and pediatric malignancies. The stability of cyclophosphamide in aqueous- and methylcellulose-based oral suspending vehicles is currently unknown. Objectives The goals of this study were (1) to develop and validate a stability-indicating HPLC method to measure cyclophosphamide concentrations in simple syrup and Ora-Plus, and (2) to assess the 56-day chemical stability and physical appearance of cyclophosphamide in these suspensions at both room temperature and 4°C. Methods The i.v. formulation of cyclophosphamide was diluted to 20 mg/mL in normal saline, compounded 1:1 with either suspending vehicle, and stored in the dark in 3mL amber polypropylene oral syringes at 4°C and 22°C. Aliquots from each syringe were obtained on days 0, 3, 7, 14, 21, 28, 35, 42, 49, and 56 and assayed using the validated stability-indicating HPLC-UV method. A C18 analytical column was used to separate cyclophosphamide from the internal standard, ifosfamide, with a mobile phase of 21% acetonitrile in 79% sodium phosphate buffer. The suspension was examined for odor change, visually examined under normal fluorescent light for color change, and examined under a light microscope for evidence of microbial growth. Results Samples of cyclophosphamide in both simple syrup and Ora-Plus were stable when kept at 4°C for at least 56 days. At room temperature, cyclophosphamide in simple syrup and Ora-Plus had a shelf life of 8 and 3 days, respectively. No changes in color or odor or evidence of microbial growth were observed. Conclusion Cyclophosphamide can be extemporaneously prepared in simple syrup or Ora-Plus and stored at least 2 months under refrigeration without significant degradation. PMID:20103616

The aim of this study was to compare survival before and after 2004 and define the prognostic factors for high-grade osteosarcomas beyond those of typical young patients with localized extremity disease. Few studies have reported the long-term treatment outcomes of high-grade osteosarcoma in Taiwan. A total of 202 patients with primary high-grade osteosarcoma who received primary chemotherapy at Taipei Veterans General Hospital between January 1995 and December 2011 were retrospectively evaluated and compared by period (1995-2003 vs 2004-2011). Patients of all ages and tumor sites and those following or not following controlled protocols were included in analysis of demographic, tumor-related, and treatment-related variables and survival. Overall survival and progression-free survival at 5 years were, respectively, 67.7% and 48% for all patients (n = 202), 77.3% and 57.1% for patients without metastasis (n = 157), and 33.9% and 14.8% for patients with metastasis (n = 45). The survival rates of patients treated after 2004 were significantly higher (by 13%-16%) compared with those of patients treated before 2004, with an accompanying 30% increase in histological good response rate (P = .002). Factors significantly contributing to inferior survival in univariate and multivariate analyses were diagnosis before 2004, metastasis at diagnosis, and being a noncandidate for a controlled treatment protocol. By comparison with the regimens used at our institution before 2004, the current results support the effectiveness of the post-2004 regimens, which consisted of substantially reduced cycles of high-dose methotrexate and a higher dosage of ifosfamide per cycle, cisplatin, and doxorubicin, for treating high-grade osteosarcoma in Asian patients.

Background: To assess the cost-effectiveness of trabectedin compared with end-stage treatment (EST) after failure with anthracycline and/or ifosfamide in metastatic soft tissue sarcoma (mSTS). Design: Analysis was carried out using a probabilistic Markov model with trabectedin → EST and EST arms, three health states (stable disease, progressive disease and death) and a lifetime perspective (3% annual discount rate). Finnish resources (drugs, mSTS, adverse events and travelling) and costs (year 2008) were used. Efficacy was based on an indirect comparison of the STS-201 and European Organisation for Research and Treatment of Cancer trials. QLQ-C30 scale scores were mapped to 15D, Short Form 6D and EuroQol 5D utilities. The outcome measures were the cost-effectiveness acceptability frontier, incremental cost per life year gained (LYG) and quality-adjusted life year (QALY) gained and the expected value of perfect information (EVPI). Results: Trabectedin → EST was associated with 14.0 (95% confidence interval 9.1–19.2) months longer survival, €36 778 higher costs (€32 816 using hospital price for trabectedin) and €31 590 (€28 192) incremental cost per LYG with an EVPI of €3008 (€3188) compared with EST. With a threshold of €50 000 per LYG, trabectedin → EST had 98.5% (98.2%) probability of being cost-effective. The incremental cost per QALY gained with trabectedin → EST was €42 633–47 735 (€37 992–42 819) compared with EST. The results were relatively insensitive to changes. Conclusion: Trabectedin is a potentially cost-effective treatment of mSTS patients. PMID:20627875

The EUROpean Bone Over 40 Sarcoma Study (EURO-B.O.S.S.) was the first prospective international study for patients 41-65 years old with high-grade bone sarcoma treated with an intensive chemotherapy regimen derived from protocols for younger patients with high-grade skeletal osteosarcoma. Chemotherapy based on doxorubicin, cisplatin, ifosfamide, and methotrexate was suggested, but patients treated with other regimens at the investigators' choice were also eligible for the study. The present report focuses on the subgroup of 218 patients with primary high-grade osteosarcoma. With a median follow-up of 47 months, the 5-year probability of overall survival (OS) was 66% in patients with localized disease and 22% in case of synchronous metastases. The 5-year OS in patients with localized disease was 29% in pelvic tumors, and 70% and 73% for extremity or craniofacial locations, respectively. In primary chemotherapy, tumor necrosis ≥90% was reported in 21% of the patients. There were no toxic deaths; however, hematological toxicity was considerable with 32% of patients experiencing 1 or more episodes of neutropenic fever. The incidence of nephrotoxicity and neurotoxicity (mainly peripheral) was 28% and 24%, respectively. After methotrexate, 23% of patients experienced delayed excretion, in 4 cases with nephrotoxicity. In patients over 40 years of age with primary high-grade osteosarcoma, an aggressive approach with chemotherapy and surgery can offer the probability of survival similar to that achieved in younger patients. Chemotherapy-related toxicity is significant and generally higher than that reported in younger cohorts of osteosarcoma patients treated with more intensive regimens.

Chemotherapy has dramatically improved the rates of cure and survival of patients with localized and metastatic osteosarcoma. Nonetheless, the number of chemotherapeutic agents active against osteosarcoma is limited to doxorubicin, cisplatin, high-dose methotrexate, and ifosfamide. Carboplatin, a cisplatin analogue, has been tested as a single agent in patients with recurrent osteosarcoma or as part of multiagent chemotherapy in newly diagnosed patients. We tested the activity and toxicity of two cycles of intraarterial carboplatin as a "window therapy" (600 mg/m2 per cycle) in 33 consecutive patients with extremity osteosarcoma before the start of multiagent chemotherapy. Response was based on clinical (tumor diameter, local inflammatory signs, and range of motion) and radiological parameters (plain local films and arteriographic studies prior to drug administration). Patients' age ranged between 8 and 18 years (median age 13 years). Primary tumor originated from the femur (15 patients), tibia (10 patients), fibula (4 patients), humerus (3 patients), and calcaneus (1 patient). Only 7 patients (21%) had metastatic disease at diagnosis (5 in the lung and 2 in other bones). A favorable clinical and radiological response was documented in 81% and 73% of the patients, respectively. Clinical and radiological progression occurred in 12% and 9% of the patients, respectively. Seventeen of the patients remain alive and disease-free. Survival and event-free survival at 3 years for nonmetastatic patients are 71% (SE = 9%) and 65% (SE = 9%), respectively; for metastatic patients, the figures are 17% (SE = 15%) and 14% (SE = 13%), respectively. We conclude that carboplatin is an active agent in the treatment of newly diagnosed extremity osteosarcoma. Copyright 1999 Wiley-Liss, Inc.

Objectives Certain patients with seminoma and clinically atypical phenotypes—visceral metastases, elevated levels of βhuman chorionic gonadotropin (βHCG), and/or recurrent disease— have a poor prognosis. The primary goal of this pilot study was to characterize the clinical characteristics and treatment profile of these rare patients. We also wished to test whether these tumors expressed any specific biomarkers that might distinguish them as a unique subtype of seminoma. Materials and methods We retrospectively identified 25 patients with a history of seminoma plus visceral metastases, βHCG levels >200 mU/ml, and/or recurrent disease. We reviewed these patients’ histories for treatment efficacy and clinical outcome. Tissue samples were available from 6 of those patients, and we studied them for expression of the markers OCT 3/4, PLAP, CD30, TRA-1-60, c-kit, and gp200. We compared our results with the expression of those markers in tissue samples from mixed seminoma/embryonal carcinomas and classic seminomas. Results Our analysis suggested that certain chemotherapeutic regimens (such as ifosfamide, paclitaxel, and cisplatin) are efficacious for the treatment of patients with these atypical seminomas. Further, specimens from the atypical seminomas generally had staining profiles that resembled those of classic seminomas and the seminoma components in mixed germ-cell tumors, but the profiles differed from those of the embryonal carcinoma components in the same mixed germ-cell tumors. Conclusions Although these atypical seminomas tend to be resistant to chemotherapy, they may still respond to certain chemotherapeutic regimens. Our pilot immunohistochemical study also suggested that the unique phenotypes associated with these atypical seminomas do not result from any relationship with embryonal carcinomas. More study is needed to confirm these initial findings. PMID:20822932

In adolescents aged 10-15 years germ cell tumors of the testis (TGCT) are rare and information for a risk adapted therapy limited. The protocol MAHO 98 for patients (pts) with TGCTs is stratified according to age, stage and histology. Pts ≥ 10 years received after tumororchiectomy 2 courses (crs) PVB and restaging. Residual tumor was resected and therapy continued in regard to inital stage and response. Chemotherapy: PVB: cisplatin (20 mg/m²/day 1-5), vinblastine (3 mg/m²/day 1+2), and bleomycin (15 U/m²/day 1-3). For consolidation 1 crs PVB has been given to stage II patients with CR. In case of PR, 2 crs PEB (vinblastine substituted by etoposide 100 mg/m²/day 1-3) or relapse 3 crs PEI (bleomycin substituted by ifosfamide 1 500 mg/m²/day 1-5) were given. Between Jan 1998 and Dec 2005, 34 pts (≥ 10 year) were registered, 31 fulfilled the inclusion criteria. Median age: 15;6 years; months (range 13;5-20;2 ). Lugano staging: IA n=14, IB n=2, IC n=3, IIA n=4, IIB n=6, IIC n=1, IIIC n=1. The stage IIIC pt received preoperative chemotherapy, all other pts had tumororchiectomy first. Residual tumor after 2 crs PVB was detected in 4 pts and was resected. Late relapses occurred in 2 pts and were cured by additional therapy. All patients are surviving. Young patients with TGCT stage I and II have an excellent prognosis and further reduction of therapy has to be considered. © Georg Thieme Verlag KG Stuttgart · New York.

Prognosis of patients with localized nasal extranodal natural killer/T-cell lymphoma, nasal type (ENKL) has been improved by non-anthracycline-containing treatments such as concurrent chemoradiotherapy (CCRT). However, some patients experience early disease progression. To clarify the clinical features and outcomes of these patients, data from 165 patients with localized nasal ENKL who were diagnosed between 2000 and 2013 at 31 institutes in Japan and who received radiotherapy with dexamethasone, etoposide, ifosfamide, and carboplatin (RT-DeVIC) were retrospectively analyzed. Progression of disease within 2 years after diagnosis (POD24) was used as the definition of early progression. An independent dataset of 60 patients with localized nasal ENKL who received CCRT at Samsung Medical Center was used in the validation analysis. POD24 was documented in 23% of patients who received RT-DeVIC and in 25% of patients in the validation cohort. Overall survival (OS) from risk-defining events of the POD24 group was inferior to that of the reference group in both cohorts (P < .00001). In the RT-DeVIC cohort, pretreatment elevated levels of serum soluble interleukin-2 receptor (sIL-2R), lactate dehydrogenase, C-reactive protein, and detectable Epstein-Barr virus DNA in peripheral blood were associated with POD24. In the validation cohort, no pretreatment clinical factor associated with POD24 was identified. Our study indicates that POD24 is a strong indicator of survival in localized ENKL, despite the different CCRT regimens adopted. In the treatment of localized nasal ENKL, POD24 is useful for identifying patients who have unmet medical needs. © 2018 The Authors.

CIC-rearranged undifferentiated small round cell sarcoma (CIC-rearranged USRCS) is a recently established type of Ewing-like small round cell sarcomas, characterized by CIC gene rearrangement, most commonly CIC-DUX4 fusion. This report presents the second case of CIC-rearranged USRCS arising primarily in the cerebrum. A 64-year-old otherwise healthy woman presented with a 1 × 1 cm sized hemorrhagic subcortical tumor in the left temporo-parietal lobe. The tumor repeatedly recurred, and the patient underwent three surgeries, chemotherapy with doxorubicin and ifosfamide, and radiotherapy, as well as gamma knife surgery. Systemic examination revealed no other extracranial masses. Imprint cytology revealed small to moderate-sized round-to-ovoid tumor cells with mild pleomorphism and variations in size and shape. The nuclei contained finely granular chromatin, and some had easily-recognizable nucleoli. The tumor exhibited a mainly cytoplasmic pattern of CD99 immunostaining, rather than a diffuse membranous pattern. The tumor also exhibited diffuse positivity for calretinin and p16, as well as partial positivity for WT1 (nuclear and cytoplasmic staining pattern) and D2-40. FISH assessment showed CIC split signals. In conclusion, CIC-rearranged USRCSs can occur primarily in the cerebrum. It would be impossible to diagnose them through cytology alone, but cytology would be useful to rule out other small round cell brain tumors including gliomas, lymphomas, carcinomas, and germinoma. Immunohistochemical analysis including tests for CD99, calretinin, and WT1 would help to suggest CIC-rearranged USRCSs and distinguish them from Ewing sarcomas. Additionally, immunohistochemistry for p16 might be useful in the diagnosis. Diagn. Cytopathol. 2016;44:828-832. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The patient was a 74-year-old man who was found to have a cutaneous mass on his left shoulder in February 2012. Because the mass bled easily and was tending to grow, total resection of the cutaneous tumor, which measured approximately 5 cm x 3 cm, was performed in July. Histopathological examination revealed a tumor that extended from the dermis to the cutaneous adipose tissue, but no invasion of the epidermis was seen. The tumor cells were plasmacytoid cells ranging in size from small to intermediate, and there was no nuclear irregularity. They had a high nuclear-cytoplasmic ratio, and nucleoli were observed. The tumor cells were CD4-positive, CD56-positive, and CD123-positive, and they were AE1/AE3-negative, CD3-negative, CD20-negative, and myeloperoxidase-negative. (18)F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT), a bone marrow examination, etc., were performed, but no lesions were detected at other sites. Based on the above findings a diagnosis of blastic plasmacytoid dendritic cell neoplasm (BPDCN), Stage IEA, was made. Because the patient had limited-stage BPDCN and was elderly, we treated him with a simultaneous combination of low-dose DeVIC (dexamethasone, VP16, ifosfamide, and carboplatin) therapy and local radiation therapy (LRT) and sustained a complete remission for approximately 1 year. Simultaneous combination of non-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy and LRT appeared to be useful in the treatment of limited-stage BPDCN even in the elderly.

Background Radiotherapy (RT) plays an important role in the multidisciplinary management of Ewing's Sarcoma (ES), especially in unresectable cases. Aim Assessment of efficacy of RT in terms of local control in pediatric patients with primary ES of bone. Materials and methods Thirty-six patients younger than 17 years old with ES treated with combined RT and chemotherapy with (N = 14) or without (N = 22) prior surgery from 1981 to 2008 were retrospectively reviewed. Since 1995, they were all treated according to the Spanish Society of Pediatric Oncology protocol (55.5% cases). Those patients received vincristine, ifosfamide, doxorubicin and etoposide. The TNM classification was as follows: 17 T1, 18 T2 and 1 T3; 36 N0; 29 M0, 5 M1a and 2 M1b. Analysis was stratified by treatment: definitive RT or pre/postoperative RT. Results The 36 patients (21 male; 15 female) had a median age of 10 years (range 2–17 years). Median follow-up of living patients was 105 months. The 2-year local control (LC) rate for all patients was 88%. Five-year LC rates for patients treated with definitive and pre/postoperative RT were 91% and 86%, respectively. Two-year overall survival and disease-free survival rates for all patients were 68% and 66%, respectively. Low phosphatase alkaline levels and local and distant recurrences were significantly predictive of worse prognosis (P = 0.021, P = 0.011, P = 0.007, respectively). Conclusion Radiotherapy with and without surgery is a highly effective local treatment option in the multidisciplinary management of ES in pediatric patients. PMID:24376965

'Double-hit lymphomas' (DHL), defined by concurrent MYC and BCL2 (or, alternatively, BCL6) rearrangements, have a very poor outcome compared to standard-risk, diffuse large B-cell lymphomas (DLBCL). Consequently, dose-intensive (DI) therapies and/or consolidation with high-dose therapy and transplant have been explored in DHL, although benefit has been debated. This meta-analysis compared survival outcomes in DHL patients receiving dose-escalated regimens [DI: R-Hyper-CVAD (rituximab, cyclophosphamide, vincristine, doxorubicin, dexamethasone) or R-CODOX-M/IVAC (rituximab, cyclophosphamide, doxorubicin, vincristine, methotrexate/ifosfamide, etoposide, high dose cytarabine); or intermediate-dose: R-EPOCH (rituximab, etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone)] versus standard-dose regimens (R-CHOP; rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) in the first-line setting. Data were synthesized to estimate hazard ratios of dose-escalated treatments versus R-CHOP using a Weibull proportional hazards model within a Bayesian meta-analysis framework. Eleven studies examining 394 patients were included. Patients were treated with either front-line R-CHOP (n = 180), R-EPOCH (n = 91), or R-Hyper-CVAD/rituximab, methotrexate, cytarabine (R-M/C), R-CODOX-M/R-IVAC (DI) (n = 123). Our meta-analysis revealed that median progression-free survival (n = 350) for the R-CHOP, R-EPOCH and DI groups was 12·1, 22·2, and 18·9 months, respectively. First-line treatment with R-EPOCH significantly reduced the risk of a progression compared with R-CHOP (relative risk reduction of 34%; P = 0·032); however, overall survival (n = 374) was not significantly different across treatment approaches. A subset of patients might benefit from intensive induction with/without transplant. Further investigation into the role of transplant and novel therapy combinations is necessary. © 2015 John Wiley & Sons Ltd.

This study aimed to explore whether peak serum methotrexate concentration (C max ) correlated with adverse events, overall survival (OS) and event-free survival (EFS) in patients with primary extremity osteosarcoma. Patients with extremity osteosarcoma who were treated at our center between 2005 and 2015 were retrospectively studied. All the patients were Enneking stage II and had received standard perioperative chemotherapy composed of high-dose methotrexate, doxorubicin, cisplatin and ifosfamide. C max and treatment-associated toxicities of each cycle were recorded. OS and EFS were estimated and compared by Kaplan-Meier survival analysis, and Cox regression models were performed for univariate comparisons. In total, 567 patients were followed for an average of 53 months (24-104 months). The estimated 3- and 5-year EFS were 71.7 and 63.1%, and the 3- and 5-year OS were 78.2 and 72.9%, respectively. C max ranged from 527 to 2495 µmol/L with a mean value of 931 ± 106 µmol/L. No significant differences in EFS and OS (p = 0.18 and p = 0.28) were observed among patients with a mean C max  > 1500, > 1000, > 700 and < 700 µmol/L. However, patients with a mean C max  > 1500 µmol/L had significantly increased rates of grade 3-5 toxicity. In the univariate analysis, C max was not a prognostic factor for EFS (p = 0.08) or OS (p = 0.16). C max did not correlate significantly with the oncologic prognosis of non-metastatic extremity osteosarcoma patients treated by multi-agent chemotherapy; however, C max correlated closely with toxicities and complications. The persistent inclusion of methotrexate in classical multidisciplinary chemotherapy was questioned and should be examined in future trials.

Metastatic extraskeletal Ewing's sarcoma treated with trabectedin: A case report.

The Ewing's sarcoma family of tumors (ESFT) comprises a number of rare malignant tumors. Standard first-line treatment for patients with these tumors includes chemotherapy with a five-drug regimen of vincristine, doxorubicin (Adriamycin ® ) and cyclophosphamide, alternating with ifosfamide and etoposide (VAC/IE). In cases of inadequate response, there are a number of second-line regimens available. However, further treatment options are required for those patients with disease unresponsive to standard treatment. Trabectedin is a novel treatment option for patients with ESFT. The present study reports the case of a Caucasian 69-year-old female patient who presented with a soft tissue mass on the chest wall that had developed 7 months earlier. A computed tomography scan revealed a 9×8×7-cm mass on the anterior chest wall above the pectoral muscle. Histopathological evaluations and molecular analysis indicated that it was consistent with a metastatic extraskeletal Ewing's sarcoma. The patient was treated with an alternating VAC/IE regimen; however, an inadequate response was observed. The patient received second-line treatment with a gemcitabine and dacarbazine combination regimen, but the disease progressed. Subsequently, treatment with trabectedin (1.5 mg/m 2 as a 24-h continuous infusion every 3 weeks) was initiated. Trabectedin treatment resulted in long-lasting (18 months) progression-free survival. It is vital that novel drugs continue to being developed for patients with ESFT following progression subsequent to standard chemotherapy. The current report presents a case of a patient with metastatic, pre-treated Ewing's sarcoma achieving disease stabilization with trabectedin. Based on these results and the observed tolerability profile, trabectedin represents an alternative treatment for patients with ESFT. Further studies are required in order to determine the efficacy of trabectedin as monotherapy or in combination with other drugs. It is also important to identify which tumor subtypes, specific translocations and patient profiles will benefit the most from treatment with trabectedin.

Activation of the insulin-like growth factor 1 (IGF-1) pathway is involved in cell growth and proliferation and is associated with tumorigenesis, tumor progression, and therapy resistance in solid tumors. We examined whether variability in serum levels of IGF-1, IGF-2, and IGF-binding protein 3 (IGF-BP3) can predict event-free survival (EFS) and overall survival (OS) in Ewing sarcoma patients treated with chemotherapy. Serum levels of IGF-1, IGF-2, and IGF-BP3 of 22 patients with localized or metastasized Ewing sarcoma treated with six cycles of vincristine/ifosfamide/doxorubicin/etoposide (VIDE) chemotherapy were recorded. Baseline levels were compared with presixth cycle levels using paired t -tests and were tested for associations with EFS and OS. Continuous variables were dichotomized according to the Contal and O'Quigley procedure. Survival analyses were performed using Cox regression analysis. High baseline IGF-1 and IGF-BP3 serum levels were associated with EFS (hazard ratio [HR] 0.075, 95% confidence interval [CI] 0.009-0.602 and HR 0.090, 95% CI 0.011-0.712, respectively) in univariate and multivariate analyses (HR 0.063, 95% CI 0.007-0.590 and HR 0.057, 95% CI 0.005-0.585, respectively). OS was improved, but this was not statistically significant. IGF-BP3 and IGF-2 serum levels increased during treatment with VIDE chemotherapy ( P =0.055 and P =0.023, respectively). High circulating serum levels of IGF-1 and IGF-BP3 and the molar ratio of IGF-1:IGF-BP3 serum levels were associated with improved EFS and a trend for improved OS in Ewing sarcoma patients treated with VIDE chemotherapy. These findings suggest the need for further investigation of the IGF-1 pathway as a biomarker of disease progression in patients with Ewing sarcoma.

Purpose Salvage chemotherapy followed by high-dose therapy and autologous stem-cell transplantation (ASCT) is the standard treatment for relapsed diffuse large B-cell lymphoma (DLBCL). Salvage regimens have never been compared; their efficacy in the rituximab era is unknown. Patients and Methods Patients with CD20+ DLBCL in first relapse or who were refractory after first-line therapy were randomly assigned to either rituximab, ifosfamide, etoposide, and carboplatin (R-ICE) or rituximab, dexamethasone, high-dose cytarabine, and cisplatin (R-DHAP). Responding patients received high-dose chemotherapy and ASCT. Results The median age of the 396 patients enrolled (R-ICE, n = 202; R-DHAP, n = 194) was 55 years. Similar response rates were observed after three cycles of R-ICE (63.5%; 95% CI, 56% to 70%) and R-DHAP (62.8%; 95 CI, 55% to 69%). Factors affecting response rates (P < .001) were refractory disease/relapse less than versus more than 12 months after diagnosis (46% v 88%, respectively), International Prognostic Index (IPI) of more than 1 versus 0 to 1 (52% v 71%, respectively), and prior rituximab treatment versus no prior rituximab (51% v 83%, respectively). There was no significant difference between R-ICE and R-DHAP for 3-year event-free survival (EFS) or overall survival. Three-year EFS was affected by prior rituximab treatment versus no rituximab (21% v 47%, respectively), relapse less than versus more than 12 months after diagnosis (20% v 45%, respectively), and IPI of 2 to 3 versus 0 to 1 (18% v 40%, respectively). In the Cox model, these parameters were significant (P < .001). Conclusion In patients who experience relapse more than 12 months after diagnosis, prior rituximab treatment does not affect EFS. Patients with early relapses after rituximab-containing first-line therapy have a poor prognosis, with no difference between the effects of R-ICE and R-DHAP. PMID:20660832

The Asháninkas, indigenous people of Peru, use cat's claw (Uncaria tomentosa) to restore health. Uncaria tomentosa has antioxidant activity and works as an agent to repair DNA damage. It causes different effects on cell proliferation depending on the cell type involved; specifically, it can stimulate the proliferation of myeloid progenitors and cause apoptosis of neoplastic cells. Neutropenia is the most common collateral effect of chemotherapy. For patients undergoing cancer treatment, the administration of a drug that stimulates the proliferation of healthy hematopoietic tissue cells is very desirable. It is important to assess the acute effects of Uncaria tomentosa on granulocyte-macrophage colony-forming cells (CFU-GM) and in the recovery of neutrophils after chemotherapy-induced neutropenia, by establishing the correlation with filgrastim (rhG-CSF) treatment to evaluate its possible use in clinical oncology. The in vivo assay was performed in ifosfamide-treated mice receiving oral doses of 5 and 15 mg of Uncaria tomentosa and intraperitoneal doses of 3 and 9 μg of filgrastim, respectively, for four days. Colony-forming cell (CFC) assays were performed with human hematopoietic stem/precursor cells (hHSPCs) obtained from umbilical cord blood (UCB). Bioassays showed that treatment with Uncaria tomentosa significantly increased the neutrophil count, and a potency of 85.2% was calculated in relation to filgrastim at the corresponding doses tested. An in vitro CFC assay showed an increase in CFU-GM size and mixed colonies (CFU-GEMM) size at the final concentrations of 100 and 200 μg extract/mL. At the tested doses, Uncaria tomentosa had a positive effect on myeloid progenitor number and is promising for use with chemotherapy to minimize the adverse effects of this treatment. These results support the belief of the Asháninkas, who have classified Uncaria tomentosa as a 'powerful plant'. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Nephroblastoma and neuroblastoma belong to the most common abdominal malignancies in childhood. Similarities in the initial presentation may provide difficulties in distinguishing between these two entities, especially if unusual variations to prevalent patterns of disease manifestation occur. Because of the risk of tumor rupture, European protocols do not require biopsy for diagnosis, which leads to misdiagnosis in some cases. We report on a 4½-year-old girl with a renal tumor displaying radiological and laboratory characteristics supporting the diagnosis of nephroblastoma. Imaging studies showed tumor extension into the inferior vena cava and bilateral lung metastases while urine catecholamines and MIBG-scintigraphy were negative. Preoperative chemotherapy with vincristine, actinomycine D and adriamycin according to the SIOP2001/GPOH protocol for the treatment of nephroblastoma was initiated and followed by surgical tumor resection. Histopathology revealed an undifferentiated tumor with expression of neuronal markers, suggestive of neuroblastoma. MYCN amplification could not be detected. DNA-microarray analysis was performed using Affymetrix genechip human genome U133 plus 2.0 and artificial neural network analysis. Results were confirmed by multiplex RT-PCR. Principal component analysis using 84 genes showed that the patient sample was clearly clustering with neuroblastoma tumors. This was confirmed by hierarchical clustering of the multiplex RT-PCR data. The patient underwent treatment for high-risk neuroblastoma comprising chemotherapy including cisplatin, etoposide, vindesine, dacarbacine, ifosfamide, vincristine, adriamycine and autologous stem cell transplantation followed by maintenance therapy with 13-cis retinoic acid (GPOH NB2004 High Risk Trial Protocol) and is in complete long-term remission. The use of gene expression profiling in an individual patient strongly contributed to clarification in a diagnostic dilemma which finally led to a change of diagnosis from nephroblastoma to neuroblastoma. This case underlines the importance of gene-expression profiling in the correct diagnosis of childhood neoplasms with atypical presentation to ensure that adequate treatment regimens can be applied.

High dose chemotherapy with autologous stem cell transplantation (HDCT-ASCT) has been administered to patients with high-risk germ cell tumours (GCT). The role of this treatment for GCT still remains unclear, including the identification of subgroups more likely to benefit from such strategy. A retrospective review was conducted of all male patients with gonadal and extra gonadal GCT treated with HDCT-ASCT between 1996 and 2008 at the Instituto Português de Oncologia de Lisboa Francisco Gentil (IPOLFG). Twenty patients were treated with HDCT-ASCT, 17 with primary testicular tumours, two mediastinal and one retroperitoneal GCT. According to the International Germ Cell Cancer Consensus Group (IGCCCG) classification, at diagnosis three patients had good risk, four intermediate, eight poor but for the patients left the risk group could not be ascertained. In eight patients HDCT-ASCT was used upfront, after induction with first-line conventional chemotherapy, and in the remaining 12 for relapsed GCT. One patient had platinum-resistant and another platinum-refractory disease. Only two patients had Beyer score > 2. All but one patient were treated with ICE (Ifosfamide, Carboplatin, Etoposide). Six patients underwent a second HDCT-ASCT course. The 5-year overall survival and progression free survival were respectively 53% and 44%; both patients with mediastinal GCT are long term survivors. Randomized studies to date have failed to indicate a survival advantage for HDCT-ASCT in GCT. This series is small and heterogeneous which prevents us from drawing conclusions regarding the benefit of this treatment for GCT. However, we could confirm the lack of benefit of HDCT-ASCT for platinum-resistant GCT and to question the absolute contraindication to this therapeutic modality in mediastinal GCT. HDCT-ASCT should therefore be performed exclusively in experienced centers and, preferably, in the setting of clinical trials.

Exome sequencing provides unprecedented insights into cancer biology and pharmacological response. Here we assess these two parameters for the NCI-60, which is among the richest genomic and pharmacological publicly available cancer cell line databases. Homozygous genetic variants that putatively affect protein function were identified in 1,199 genes (approximately 6% of all genes). Variants that are either enriched or depleted compared to non-cancerous genomes, and thus may be influential in cancer progression and differential drug response were identified for 2,546 genes. Potential gene knockouts are made available. Assessment of cell line response to 19,940 compounds, including 110 FDA-approved drugs, reveals ≈80-fold range in resistance versus sensitivity response across cell lines. 103,422 gene variants were significantly correlated with at least one compound (at p<0.0002). These include genes of known pharmacological importance such as IGF1R, BRAF, RAD52, MTOR, STAT2 and TSC2 as well as a large number of candidate genes such as NOM1, TLL2, and XDH. We introduce two new web-based CellMiner applications that enable exploration of variant-to-compound relationships for a broad range of researchers, especially those without bioinformatics support. The first tool, “Genetic variant versus drug visualization”, provides a visualization of significant correlations between drug activity-gene variant combinations. Examples are given for the known vemurafenib-BRAF, and novel ifosfamide-RAD52 pairings. The second, “Genetic variant summation” allows an assessment of cumulative genetic variations for up to 150 combined genes together; and is designed to identify the variant burden for molecular pathways or functional grouping of genes. An example of its use is provided for the EGFR-ERBB2 pathway gene variant data and the identification of correlated EGFR, ERBB2, MTOR, BRAF, MEK and ERK inhibitors. The new tools are implemented as an updated web-based CellMiner version, for which the present publication serves as a compendium. PMID:25032700

As the efficacy of all pediatric high-grade glioma (HGG) treatments is similar and still disappointing, it is essential to also investigate the toxicity of available treatments. Prospectively recorded hematologic and nonhematologic toxicities of children treated with radiochemotherapy in the HIT GBM-C/D and HIT-HGG-2007 trials were compared. Children aged 3-18 years with histologically proven HGG (WHO grade III and IV tumors) or unequivocal radiologic diagnosis of diffuse intrinsic pontine glioma (DIPG) were included in these trials. The HIT-HGG-2007 protocol comprised concomitant radiochemotherapy with temozolomide, while cisplatinum/etoposide (PE) and PE plus ifosfamide (PEI) in combination with weekly vincristine injections were applied during radiochemotherapy in the HIT GBM-C/D protocol. Regular blood counts and information about cellular nadirs were available from 304 patients (leukocytes) and 306 patients (thrombocytes), respectively. Grade 3-4 leukopenia was much more frequent in the HIT GBM-C/D cohort (n = 88, 52%) vs. HIT-HGG-2007 (n = 13, 10%; P <0.001). Grade 3-4 thrombopenia was also more likely in the HIT GBM-C/D cohort (n = 21, 12% vs. n = 3,2%; P <0.001). Grade 3-4 leukopenia appeared more often in children aged 3-7 years (n = 38/85, 45%) than in children aged 8-12 years (n = 39/120, 33%) and 13-18 years (24/100, 24%; P =0.034). In addition, sickness was more frequent in the HIT GBM-C/D cohort (grade 1-2: 44%, grade 3-4: 6% vs. grade 1-2: 28%, grade 3-4: 1%; P <0.001). Radiochemotherapy involving cisplatinum-based polychemotherapy is more toxic than radiotherapy in combination with temozolomide. Without evidence of differences in therapeutic efficacy, the treatment with lower toxicity, i. e., radiotherapy with temozolomide should be used.

Following promising results to increase survival and reduce treatment burden in intracranial non-germinomatous germ cell tumors (NGGCTs), we conducted a European study using dose-intense chemotherapy followed by risk-adapted radiotherapy. All patients received 4 courses of cisplatin/etoposide/ifosfamide. Non-metastatic patients then received focal radiotherapy only (54 Gy); metastatic patients received 30 Gy craniospinal radiotherapy with 24 Gy boost to primary tumor and macroscopic metastatic sites. Patients with localized malignant NGGCT (n = 116) demonstrated 5-year progression-free survival (PFS) and overall survival (OS) of 0.72 ± 0.04 and 0.82 ± 0.04, respectively. Primary tumor sites were: 67 pineal, 35 suprasellar, 5 bifocal, 9 others. One patient died postsurgery in clinical remission; 3 patients progressed during treatment and 27 (23%) relapsed afterward. Fourteen were local, 6 combined, and 7 distant relapses (outside radiation field). Seventeen of the 27 relapsed patients died of disease. Patients with metastatic disease (n = 33) demonstrated 5-year PFS and OS of 0.68 ± 0.09 and 0.75 ± 0.08, respectively; 1 patient died following progression on treatment and 9 (27%) relapsed afterward (5 local, 1 combined, 3 distant). Only one metastatic patient with recurrence was salvaged. Multivariate analysis identified diagnostic alpha-fetoprotein level (serum and/or cerebrospinal fluid level >1000 ng/mL, 19/149 patients, of whom 11 relapsed; P < 0.0003) and residual disease following treatment, including after second-look surgery (n = 52/145 evaluable patients, 26 relapsed; P = 0.0002) as significant prognostic indicators in this cohort. In localized malignant NGGCT, craniospinal radiotherapy could be avoided without increased relapses outside the radiotherapy field. Chemotherapy and craniospinal radiotherapy remain the gold standard for metastatic disease. © The Author(s) 2017. Published by Oxford University Press on behalf of the Society for Neuro-Oncology.

We experienced a 38-year-old Japanese male with t(10;19) CIC-DUX4 -positive undifferentiated small round cell sarcoma in the deep abdominal wall. Three months before his first visit to our hospital, he noticed a mass in his right abdominal wall. Computed tomography on admission revealed a solid abdominal tumor 70×53mm in size and multiple small tumors in both lungs. The biopsy of the abdominal tumor revealed undifferentiated small round cell sarcoma, suggestive of Ewing sarcoma. Under the clinical diagnosis of Ewing-like sarcoma of the abdominal wall with multiple lung metastases, several cycles of ICE (ifosfamide, carboplatin and etoposide) therapy were performed. After the chemotherapy, the lung metastases disappeared, while the primary lesion rapidly grew. Additional VDC (vincristine, doxorubicin and cyclophosphamide) therapy was carried out without apparent effect. Although the surgical removal of the primary lesion was done, peritoneal dissemination and a huge metastatic liver tumor appeared thereafter. The patient died of disease progression two months after the surgery. The total clinical course was approximately one year, showing that the tumor was extremely aggressive. The tumor cells of the surgical specimen were positive for CD99, WT1, calretinin, INI1, ERG and Fli1 by immunohistochemistry. Fusion gene analyses using the frozen surgical material revealed negativity for EWSR1-Fli1, EWSR1-ERG and t(4;19) CIC-DUX4 fusions, but positivity for t(10;19) CIC-DUX4 fusion. Thus, we made a final pathological diagnosis of t(10;19) CIC-DUX4-positive undifferentiated small round cell sarcoma. To our knowledge, this is the 13th case of t(10;19) CIC-DUX4 undifferentiated small round cell sarcoma with precise clinicopathological information. Especially in our case, two types of t(10;19) CIC-DUX4 fusion transcripts were observed, both of which are in-frame and novel. Copyright © 2017 Elsevier GmbH. All rights reserved.

To clarify the significance of the International Germ Cell Cancer Collaborative Group classification in the 2000s, especially in intermediate- and poor-prognosis testicular germ cell tumor in Japan. We retrospectively analyzed 117 patients with intermediate- and poor-prognosis testicular non-seminomatous germ cell tumor treated at five university hospitals in Japan between 2000 and 2010. Data collected included age, levels of tumor markers, spread to non-pulmonary visceral metastases, treatment details and survival. The median follow-up period of all patients was 57 months. A total of 50 patients (43%) were classified as having intermediate prognosis, and 67 patients (57%) as poor prognosis according to the International Germ Cell Cancer Collaborative Group classification. As first-line chemotherapy, 92 patients (79%) received bleomycin, etoposide and cisplatin. Of all patients, 74 patients (63%) received second-line chemotherapy. The most commonly used second-line chemotherapy regimens were a combination of taxanes, ifosfamide and platinum in 49 cases (66%). Overall, 33 patients (28%) received third-line chemotherapy. A total of 88 patients (75%) underwent post-chemotherapy surgery. The 5-year overall survival for intermediate (n = 50) and poor prognosis (n = 67) was 89% and 83% (P = 0.21), respectively. In poor prognosis patients, patients with two or more risk factors (any of high lactic dehydrogenase, alpha-fetoprotein and human chorionic gonadotropin levels, and presence of non-pulmonary visceral metastases) had significantly worse survival than those with only one risk factor (71% and 91%, respectively, P = 0.01). The 5-year overall survivals of poor-prognosis testicular non-seminomatous germ cell tumor patients reached 83%. Further stratification of poor-prognosis patients based on a number of risk factors has the potential to further identify those with poorer prognosis. © 2015 The Japanese Urological Association.

The clinical impact of positron emission tomography (PET) evaluation performed early during first-line therapy in patients with advanced-stage Hodgkin lymphoma, in terms of providing a rationale to shift patients who respond poorly onto a more intensive regimen (PET response-adapted therapy), remains to be confirmed. The phase II part of the multicenter HD0801 study involved 519 patients with advanced-stage de novo Hodgkin lymphoma who received an initial treatment with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and who underwent an early ifosfamide-containing salvage treatment followed by stem-cell transplantation if they showed a positive PET evaluation after two cycles of chemotherapy (PET2). The primary end point was 2-year progression-free survival calculated for both PET2-negative patients (who completed a full six cycles of ABVD treatment) and PET2-positive patients. Overall survival was a secondary end point. In all, 103 of the 512 evaluable patients were PET2 positive. Among them, 81 received the scheduled salvage regimen with transplantation, 15 remained on ABVD (physician's decision, mostly because of minimally positive PET2), five received an alternative treatment, and two were excluded because of diagnostic error. On intention-to-treat analysis, the 2-year progression-free survival was 76% for PET2-positive patients (regardless of the salvage treatment they received) and 81% for PET2-negative patients. Patients with advanced-stage Hodgkin lymphoma for whom treatment was at high risk of failing appear to benefit from early treatment intensification with autologous transplantation, as indicated by the possibility of successful salvage treatment in more than 70% of PET2-positive patients through obtaining the same 2-year progression-free survival as the PET2-negative subgroup. © 2016 by American Society of Clinical Oncology.

Hematopoietic growth factors (HGFs) have been used to reduce the neutropenic complications of cytotoxic chemotherapy so that higher doses may be given. The authors have previously shown that endogenous serum granulocyte-colony stimulating factor (G-CSF) and granulocyte-macrophage-colony stimulating factor (GM-CSF) levels at night (p.m.) were significantly higher than those in the morning (a.m.). Twenty-four patients with soft tissue or bone sarcoma who were treated with high dose ifosfamide-based chemotherapy were enrolled in this study. Patients were randomized to either a.m. or p.m. treatment. GM-CSF was administered at a dose of 5 microg/kg/day at 10 a.m. or 10 p.m., beginning 36-48 hours after the last chemotherapy dose. GM-CSF therapy was continued until the neutrophil count exceeded 1,000/mm3 for 2 consecutive days. Leukocyte, neutrophil, monocyte, and platelet counts were measured immediately before GM-CSF administration and exactly 12 hours after the first dose of GM-CSF, and every 24 hours until 3 days after the cessation of GM-CSF. The mean duration of Grade 3-4 neutropenia was 5.3 +/- 0.4 days for the a.m. treatment arm and 6.5 +/- 0.3 days for the p.m. treatment arm (P = 0.017). Although the duration of neutropenia in the a.m. arm was significantly shorter than in the p.m. arm, there were no differences related to the number of febrile neutropenic episodes or the duration of antibiotic administration. Also, there were no differences in the side effects observed in the a.m. and p.m. arms. The finding of 1.2 days' difference in the duration of Grade 3-4 neutropenia warrants further study of chronotherapy with HGFs.

Slow down to stay alive: HER4 protects against cellular stress and confers chemoresistance in neuroblastoma.

Neuroblastoma (NBL) is a common pediatric solid tumor, and outcomes for patients with advanced neuroblastoma remain poor despite extremely aggressive treatment. Chemotherapy resistance at relapse contributes heavily to treatment failure. The poor survival of patients with high-risk NBL prompted this investigation into novel treatment options with the objective of gaining a better understanding of resistance mechanisms. On the basis of previous work and on data from publicly available studies, the authors hypothesized that human epidermal growth factor receptor 4 (Her4) contributes to resistance. Her4 expression was reduced with small-hairpin RNA (shRNA) to over express intracellular HER4, and the authors tested its impact on tumor cell survival under various culture conditions. The resulting changes in gene expression after HER4 knockdown were measured by using a messenger RNA (mRNA) array. HER4 expression was up-regulated in tumor spheres compared with the expression in monolayer culture. With HER4 knockdown, NBL cells became less resistant to anoikis and serum starvation. Moreover, HER4 knockdown increased the chemosensitivity of NBL cells to cisplatin, doxorubicin, etoposide, and activated ifosfamide. In mRNA array analysis, HER4 knockdown predominately altered genes related to cell cycle regulation. In NBL spheres compared with monolayers, cell proliferation was decreased, and cyclin D expression was reduced. HER4 knockdown reversed cyclin D suppression. Overexpressed intracellular HER4 slowed the cell cycle and induced chemoresistance. The current results indicated that HER4 protects NBL cells from multiple exogenous apoptotic stimuli, including anoikis, nutrient deficiency, and cytotoxic chemotherapy. The intracellular fragment of HER4 was sufficient to confer this phenotype. HER4 functions as a cell cycle suppressor, maintaining resistance to cellular stress. The current findings indicate that HER4 overexpression may be associated with refractory disease, and HER4 may be an important therapeutic target. Copyright © 2012 American Cancer Society.

Supra-tentorial primitive neuroectodermal tumors (SPNET) are high-grade, hemispheric tumors, which account for around 2-3 % of pediatric brain tumors. We herein intend to report the clinical features and treatment outcome of patients with nonpineal SPNET treated at our institute. Clinical data were collected by retrospective chart review from 2006 to 2012. Histopathology slides were reviewed, and relevant immunohistochemistry stains were done. Overall survival (OS), recurrence-free survival (RFS) and event-free survival (EFS) were analyzed by the Kaplan-Meier product-limit method. Fifteen patients met the study criterion (male: female = 2:1). Median age at presentation was 11 years (range 3-49 years). Surgical resection was gross total in 6 (40%) and subtotal in 8 (53.33%) patients. At presentation, two patients had leptomeningeal dissemination. Radiation therapy was delivered in 11 (73.33%) patients: craniospinal irradiation in 8 (36 Gy/20 fractions/4 weeks to the craniospinal axis followed by a local boost of 20 Gy/10 fractions/2 weeks) and focal RT in 3 patients. Systemic chemotherapy (median 6 cycles; range 1-16 cycles), given in 13 (86.67%) patients, included the VAC regimen (vincristine, adriamycin, cyclophosphamide) alternating with IE (ifosfamide,etoposide). After a median follow-up of 22.6 months (mean, 24.47 months), complete response and progressive disease were noted in 8 (53.33%) and 7 (46.67%) patients, respectively. Median OS was not reached, and estimated median EFS was noted to be 4.12 years (actuarial rate of EFS at 2 years, 55.2%). Maximal safe resection followed by craniospinal irradiation and systemic chemotherapy with 6-12 cycles of an alternating regimen of VAC and IE is a reasonable treatment strategy in patients with nonpineal SPNET.

The toxicity of dose-intensive regimens used for Burkitt lymphoma prompted modification of cyclophosphamide, vincristine, doxorubicin, high-dose methotrexate/ifosfamide, etoposide, and high-dose cytarabine (CODOX-M/IVAC) for HIV-positive patients. We added rituximab, reduced and/or rescheduled cyclophosphamide and methotrexate, capped vincristine, and used combination intrathecal chemotherapy. Antibiotic prophylaxis and growth factor support were required; highly active antiretroviral therapy (HAART) was discretionary. Thirteen AIDS Malignancy Consortium centers enrolled 34 patients from 2007 to 2010. Median age was 42 years (range, 19-55 years), 32 of 34 patients were high risk, 74% had stage III to IV BL and CD4 count of 195 cells per μL (range, 0-721 cells per μL), and 5 patients (15%) had CD4 <100 cells per μL. Twenty-six patients were receiving HAART; viral load was <100 copies per mL in 12 patients. Twenty-seven patients had at least one grade 3 to 5 toxicity, including 20 hematologic, 14 infectious, and 6 metabolic. None had grade 3 to 4 mucositis. Five patients did not complete treatments because of adverse events. Eleven patients died, including 1 treatment-related and 8 disease-related deaths. The 1-year progression-free survival was 69% (95% confidence interval [CI], 51%-82%) and overall survival was 72% (95% CI, 53%-84%); 2-year overall survival was 69% (95% CI, 50%-82%). Modifications of the CODOX-M/IVAC regimen resulted in a grade 3 to 4 toxicity rate of 79%, which was lower than that in the parent regimen (100%), without grade 3 to 4 mucositis. Despite a 68% protocol completion rate, the 1-year survival rate compares favorably with 2 studies that excluded HIV-positive patients. This trial was registered at http://clinicaltrials.gov as #NCT00392834. © 2015 by The American Society of Hematology.

Treatment of Burkitt lymphoma (BL) with intensive, multi-agent chemotherapy with aggressive central nervous system (CNS) prophylaxis results in high cure rates, although no regimen is standard of care. We examined population-based survival outcomes of adults with BL treated with a modified combination of cyclophosphamide, vincristine, doxorubicin, prednisone and systemic high-dose methotrexate (MTX) (CODOX-M) with IVAC (ifosfamide, mesna, etoposide, cytarabine and intrathecal MTX) (CODOX-M/IVAC) ± rituximab over a 15-year period in British Columbia. For the 81 patients identified (including 8 with CNS involvement and 18 with human immunodeficiency virus-associated BL), 5-year progression-free survival (PFS) and overall survival (OS) were 75% [95% confidence interval (CI): 63-83%] and 77% (95% CI: 66-85%), respectively, with no treatment-related deaths. Those who completed the regimen per protocol (n = 38) had significantly improved 5-year PFS 86% (P = 0·04) and OS 92% (P = 0·008), as did those under 60 years with 5-year PFS 82% (P = 0·005) and OS 86% (P = 0·002), which remained significant in multivariate analysis [PFS: hazard ratio (HR) 3·36, P = 0·018; OS HR 4·03, P = 0·012]. Incorporation of high-dose systemic methotrexate also significantly affected multivariate survival outcomes (OS HR 0·28, P = 0·025). Stem cell transplant in first remission had no effect on OS or PFS. This large, real-world analysis of BL patients treated with CODOX-M/IVAC ± rituximab demonstrates excellent survival outcomes comparable to clinical trials. These results help to serve as a benchmark when comparing curative therapies for BL patients as novel regimens are incorporated into clinical practice. © 2018 John Wiley & Sons Ltd.

Stability of solutions of antineoplastic agents during preparation and storage for in vitro assays. General considerations, the nitrosoureas and alkylating agents.

PubMed

1985-01-01

In vitro drug sensitivity of tumour biopsies is currently being determined using a variety of methods. For these chemosensitivity assays many drugs are required at short notice, and this in turn means that the drugs must generally be stored in solution. There are, however, a number of potential problems associated with dissolving and storing drugs for in vitro use, which include (a) drug adsorption; (b) effects of freezing; (c) drug stability under the normal conditions of dilution and setting up of an in vitro assay; and (d) insolubility of drugs in normal saline (NS) or phosphate-buffered saline (PBS). These problems are considered in general, and some recommendations for use of solutions of drugs in in vitro assays are suggested. The nitrosoureas and alkylating agents are also investigated in greater detail in this respect. The nitrosoureas are found to be very labile in PBS at pH 7, with 5% degradation (t0.95) occurring in 10-50 min at room temperature. These values are increased about 10-fold on refrigeration and about 5- to 10-fold on reduction of the pH of the medium to pH 4-5. At pH 7 and room temperature, t0.95 is observed in under 1 h with the alkylating agents nitrogen mustard, chlorambucil, melphalan, 2,5-diaziridinyl-3,6-bis(2-hydroxyethylamino)-1,4-benzoquinone (BZQ), dibromodulcitol, dibromomannitol, treosulphan, and procarbazine. Of the other alkylating agents, 4-hydroperoxycylophosphamide (sometimes used in vitro in place of cyclophosphamide), busulphan, dianhydrogalactitol, aziridinylbenzoquinone (AZQ), and dacarbazine have a t0.95 of between 2 and 24 h, while ifosfamide and pentamethylmelamine are both stable in aqueous solution for greater than 7 days. About half the drugs studied in detail have been stored frozen in solution for in vitro use, although very little is known about their stability under these conditions.

This study aimed to address the insufficiency of traditional meta-analysis and provide improved guidelines for the clinical practice of osteosarcoma treatment. The heterogeneity of the fixed-effect model was calculated, and when necessary, a random-effect model was adopted. Furthermore, the direct and indirect evidence was pooled together and exhibited in the forest plot and slash table. The surface under the cumulative ranking curve (SUCRA) value was also measured to rank each intervention. Finally, heat plot was introduced to demonstrate the contribution of each intervention and the inconsistency between direct and indirect comparisons. This network meta-analysis included 32 trials, involving a total of 5,626 subjects reported by 28 articles. All the treatments were classified into six chemotherapeutic combinations: dual agent with or without ifosfamide (IFO), multi-agent with or without IFO, and dual agent or multi-agent with IFO and etoposide. For the primary outcomes, both overall survival (OS) and event-free survival (EFS) rates were considered. The multi-agent integrated with IFO and etoposide showed an optimal performance for 5-year OS, 10-year OS, 3-year EFS, 5-year EFS, and 10-year EFS when compared with placebo. The SUCRA value of this treatment was also the highest of these six interventions. However, multi-drug with IFO alone had the highest SUCRA value of 0.652 and 0.516 when it came to relapse and lung-metastasis. It was efficient to some extent, but no significant difference was observed in both outcomes. Chemotherapy, applied as induction or adjuvant treatment with radiation therapy or surgery, is able to increase the survival rate of patients, especially by combining multi-drug with IFO and etoposide, which demonstrated the best performance in both OS and EFS. As for relapse and the lung-metastasis, multiple agents with IFO alone seemed to have the optimal efficiency, although no significant difference was observed here. J. Cell.

Results of previous study showed promising but short-lived activity of sorafenib in the treatment of patients with unresectable advanced and metastatic osteosarcoma. This treatment failure has been attributed to the mTOR pathway and might therefore be overcome with the addition of mTOR inhibitors. We aimed to investigate the activity of sorafenib in combination with everolimus in patients with inoperable high-grade osteosarcoma progressing after standard treatment. We did this non-randomised phase 2 trial in three Italian Sarcoma Group centres. We enrolled adults (≥18 years) with relapsed or unresectable osteosarcoma progressing after standard treatment (methotrexate, cisplatin, and doxorubicin, with or without ifosfamide). Patients received 800 mg sorafenib plus 5 mg everolimus once a day until disease progression or unacceptable toxic effects. The primary endpoint was 6 month progression-free survival (PFS). All analyses were intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT01804374. We enrolled 38 patients between June 16, 2011, and June 4, 2013. 17 (45%; 95% CI 28-61) of 38 patients were progression free at 6 months. Toxic effects led to dose reductions, or short interruptions, or both in 25 (66%) of 38 patients and permanent discontinuation for two (5%) patients. The most common grade 3-4 adverse events were lymphopenia and hypophosphataemia each in six (16%) patients, hand and foot syndrome in five (13%), thrombocytopenia in four (11%), and fatigue, oral mucositis, diarrhoea, and anaemia each in two (5%). One patient (3%) had a grade 3 pneumothorax that required trans-thoracic drainage, and that recurred at the time of disease progression. This was reported as a serious adverse event related to the study drugs in both instances. No other serious adverse events were reported during the trial. There were no treatment-related deaths. Although the combination of sorafenib and everolimus showed activity as a further-line treatment for patients with advanced or unresectable osteosarcoma, it did not attain the prespecified target of 6 month PFS of 50% or greater.

Three-dimensional Cell Culture Devices for Cancer Migration and Drug Testing

NASA Astrophysics Data System (ADS)

Ma, Liang

Porous polymeric materials are widely used to mimic the extracellular matrix (ECM) environment for applications such as 3D cell culturing and tissue engineering. A series of comparative experiments on 3D cell cultures both in PLA porous scaffolds and alginate gels were conducted to create an in vitro tumor model. A novel 3D cell culture device based on porous polymeric material was developed to study cancer migration. Significant cell migration was observed through the porous channel within 1--2 weeks induced by 20% fetal bovine serum (FBS). A three-dimensional micro-scale perfusion-based two-chamber (3D-muPTC) tissue model system was developed to test the cytotoxicity of anticancer drugs by emulating liver metabolism effects in vitro. Hepatoma cells and glioblastoma multiforme (GBM) cancer cells were cultured in porous polymeric scaffolds in two separate chambers, representing the liver and tumor, respectively. The cytotoxic effect of temozolomide (TMZ) was first tested using this system. It was found that the GBM cells showed a much higher viability under the TMZ treatment with liver cells in the system, suggesting that the drug metabolism in liver is affecting the efficacy of the drug. The favorable metabolism effect of cytochrome P450 (CYP) was tested using a prodrug ifosfamide (IFO). Without the liver cells, IFO showed only slight toxicity to GBM cells. Moreover, it was shown that different expression levels of CYP 3A4, a major drug metabolizing enzyme, in liver cells caused significantly different levels of GBM cell viability. Simulation of the flow characteristics in the 3D-muPTC system was conducted using the finite-element analysis approach. The shear stress was predicted in the porous scaffolds under different flow rate conditions. The predicted shear stress effects agreed well with an experimental cell viability study. A low cost organic solvent free approach to fabricating tissue engineering scaffolds was developed by combining the twin-screw extrusion and particulate leaching. High porosity and interconnected porous PLA scaffolds with the pore size 50 to 200μm were fabricated with this immiscible polymer blending method. This combined extrusion and particulate leaching method provides a new technique to fabricate tissue engineering scaffolds that can be used in the 3D-muPTC device.

Liposarcoma is the most common type of soft tissue sarcoma (STS). It is divided into five groups according to histological pattern: well-differentiated, myxoid, round cell, pleomorphic, and dedifferentiated. Dedifferentiated liposarcoma most commonly occurs in the retroperitoneum, while an intraperitoneal location is extremely rare. Only seven cases have been reported in literature. Many pathologists recognize that a large number of intra-abdominal poorly differentiated sarcomas are dedifferentiated liposarcomas. We report a case initially diagnosed as undifferentiated sarcoma that was reclassified as intraperitoneal dedifferentiated liposarcoma showing an amplification of the MDM2 gene. A 59-year-old woman with abdominal pain and constipation was referred to the Department of Advanced Biomedical Sciences, University of Naples Federico II, Naples, Italy, in November 2012. On physical examination, a very large firm mass was palpable in the meso-hypogastrium. Computed tomography (CT) scan showed a heterogeneous density mass (measuring 10 × 19 cm) that was contiguous with the mesentery and compressed the third part of the duodenum and jejunum.At laparotomy, a large mass occupying the entire abdomen was found, adhering to the first jejunal loop and involving the mesentery. Surgical removal of the tumor along with a jejunal resection was performed because the first jejunal loop was firmly attached to the tumor.Macroscopic examination showed a solid, whitish, cerebroid, and myxoid mass, with variable hemorrhage and cystic degeneration, measuring 26 × 19 × 5 cm. Microscopic examination revealed two main different morphologic patterns: areas with spindle cells in a myxoid matrix and areas with pleomorphic cells. The case was initially diagnosed as undifferentiated pleomorphic sarcoma. Histological review showed areas of well-differentiated liposarcoma. Fluorescence in situ hybridization (FISH) analysis was performed and demonstrated an amplification of the MDM2 gene. Definitive diagnosis was intraperitoneal dedifferentiated liposarcoma.No adjuvant therapy was given, but 5 months after laparotomy, the patient presented with a locoregional recurrence and chemotherapy with high-dose ifosfamide was started. No guidelines are available for the management of intraperitoneal dedifferentiated liposarcoma. We report this case to permit the collection of a larger number of cases to improve understanding and management of this tumor. Moreover, this study strongly suggests that poorly differentiated sarcomas should prompt extensive sampling to demonstrate a well-differentiated liposarcoma component and, if possible, FISH analysis.

The role of chemotherapy in high-risk soft tissue sarcoma is controversial. Though many patients undergo initial curative resection, distant metastasis is a frequent event, resulting in 5-year overall survival rates of only 50-60%. Neo-adjuvant and adjuvant chemotherapy (CTX) has been applied to achieve pre-operative cytoreduction, assess chemosensitivity, and to eliminate occult metastasis. Here we report on the results of our non-randomized phase II study on neo-adjuvant treatment for high-risk STS. Patients with potentially curative high-risk STS (size ≥ 5 cm, deep/extracompartimental localization, tumor grades II-III [FNCLCC]) were included. The protocol comprised 4 cycles of neo-adjuvant chemotherapy (EIA, etoposide 125 mg/m(2) iv days 1 and 4, ifosfamide 1500 mg/m2 iv days 1 - 4, doxorubicin 50 mg/m(2) day 1, pegfilgrastim 6 mg sc day 5), definitive surgery with intra-operative radiotherapy, adjuvant radiotherapy and 4 adjuvant cycles of EIA. Between 06/2005 and 03/2010 a total of 50 subjects (male = 33, female = 17, median age 50.1 years) were enrolled. Median follow-up was 30.5 months. The majority of primary tumors were located in the extremities or trunk (92%), 6% originated in the abdomen/retroperitoneum. Response by RECIST criteria to neo-adjuvant CTX was 6% CR (n = 3), 24% PR (n = 12), 62% SD (n = 31) and 8% PD (n = 4). Local recurrence occurred in 3 subjects (6%). Distant metastasis was observed in 12 patients (24%). Overall survival (OS) and disease-free survival (DFS) at 2 years was 83% and 68%, respectively. Multivariate analysis failed to prove influence of resection status or grade of histological necrosis on OS or DFS. Severe toxicities included neutropenic fever (4/50), cardiac toxicity (2/50), and CNS toxicity (4/50) leading to CTX dose reductions in 4 subjects. No cases of secondary leukemias were observed so far. The current protocol is feasible for achieving local control rates, as well as OS and DFS comparable to previously published data on neo-/adjuvant chemotherapy in this setting. However, the definitive role of chemotherapy remains unclear in the absence of large, randomized trials. Therefore, the current regimen can only be recommended within a clinical study, and a possibly increased risk of secondary leukemias has to be taken into account.

Herbal-drug interaction induced rhabdomyolysis in a liposarcoma patient receiving trabectedin

PubMed Central

2013-01-01

Background Rhabdomyolysis is an uncommon side effect of trabectedin which is used for the second line therapy of metastatic sarcoma after anthracycline and ifosfamide failure. This side effect may be due to pharmacokinetic interactions caused by shared mechanisms of metabolism involving the cytochrome P450 (CYP) system in the liver. Here, for the first time in literature, we describe the unexpected onset of heavy toxicity, including rhabdomyolysis, after the fourth course of trabectedin in a patient with retroperitoneal liposarcoma who at the same time was taking an alternative herbal medicine suspected of triggering this adverse event. Case presentation This is the case of a 56 year old Caucasian man affected by a relapsed de-differentiated liposarcoma who, after the fourth cycle of second-line chemotherapy with trabectedin, complained of sudden weakness, difficulty walking and diffuse muscle pain necessitating complete bed rest. Upon admission to our ward the patient showed grade (G) 4 pancytopenia and a marked increase in liver lytic enzymes, serum levels of myoglobin, creatine phosphokinase (CPK) and lactate dehydrogenase. No cardiac or kidney function injuries were present. Based on these clinical and laboratory features, our conclusive diagnosis was of rhabdomyolysis induced by trabectedin. The patient did not report any trauma or muscular overexertion and no co-morbidities were present. He had not received any drugs during treatment with trabectedin, but upon further questioning the patient informed us he had been taking a folk medicine preparation of chokeberry (Aronia melanocarpa) daily during the last course of trabectedin and in the 2 subsequent weeks. One week after hospitalization and cessation of intake of chokeberry extract, CPK and other markers of myolysis slowly returned to standard range, and the patient noted a progressive recovery of muscle strength. The patient was discharged on day 14 when a blood transfusion and parenteral hydration gradually lowered general toxicity. Progressive mobilization of the patient was obtained as well as a complete normalization of the laboratory findings. Conclusions The level of evidence of drug interaction leading to the adverse event observed in our patient was 2 (probable). Thus our case underlines the importance of understanding rare treatment-related toxicities such as trabectedin-induced rhabdomyolysis and the possible role of the drug-drug interactions in the pathogenesis of this rare side effect. Furthermore, this report draws attention to a potential problem of particular concern, that of nutritional supplements and complementary and alternative drug interactions. These are not widely recognized and can cause treatment failure. PMID:23899130

A 24-year-old African American female (L.R.) with a history of smoking and gestational diabetes was diagnosed with Hodgkin lymphoma. She received multiple chemotherapies, including six cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), followed by radiation therapy to left inguinal areas for a total of 30.6 Gy in 17 fractions; she obtained complete remission. Two years later, L.R. had disease relapse in the mediastinum and received two cycles of ESHAP (etoposide, methylprednisolone, high-dose cytarabine, cisplatin) followed by etoposide and ifosfamide. She then received BEAM (carmustine, etoposide, cytarabine, and melphalan) as a conditioning regimen and underwent autologous bone marrow transplant. Her post-transplant course was complicated by cytomegalovirus antigenemia, aspergillus pneumonia, and congestive heart failure with left ventricular ejection fraction (LVEF) of 20%–25%. She was treated with an ACE inhibitor (lisinopril) and a beta-blocker (carvedilol) with improvement of her LVEF to 30%–35%. A follow-up chest x-ray showed an increase in the size of the anterior mediastinal adenopathy suspicious for relapse of lymphoma, and at the same time she was also found to be 5 weeks pregnant. Given her cardiomyopathy, significant obesity, poorly controlled diabetes, and cancer recurrence, L.R. was advised by her gynecologist that the pregnancy was very high risk and might not be viable. The oncologists advised her to terminate the pregnancy within the first trimester, as she needed salvage radiotherapy treatment to the mediastinum and chemotherapy treatments that might endanger the fetus. However, the patient decided to continue with the pregnancy. A multidisciplinary team—which included a cardiologist, oncologist, high-risk obstetrician, pharmacist, and nurse practitioner—was then involved to provide care during the pregnancy. A social worker was also solicited to help with home and financial issues because L.R. was a single mother with a 2-year-old son. L.R. was treated with carvedilol and furosemide, with monthly cardiology clinical follow-up during the first and second trimesters, then every 2 weeks starting with the 28th week, and weekly thereafter until delivery. Between visits, she notified the clinic for symptoms of heart failure exacerbation and was seen as necessary. The possible in utero effects of both medications were discussed with the patient. L.R. had a normal uncomplicated pregnancy and delivered a 6-pound, 10-ounce healthy boy at 39 weeks via vaginal delivery and was discharged home 2 days later. A week after delivery, L.R. presented to the cardiology clinic in good spirits and was excited to show pictures of her newborn baby. She had no cardiac complaints and the repeat echocardiogram showed an unchanged LVEF of 30%–35%. PMID:25031933

What is the effect of different alkylating agents used without pelvic radiation to treat childhood cancer in girls on the ovarian reserve in survivors? Ovarian reserve seems to be particularly reduced in survivors who received procarbazine (in most cases for Hodgkin lymphoma) or high-dose chemotherapy; procarbazine but not cyclophosphamide dose is associated with diminished ovarian reserve. A few studies have demonstrated diminished ovarian reserve in survivors after various combination therapies, but the individual role of each treatment is difficult to assess. Prospective cross-sectional study, involving 105 survivors and 20 controls. One hundred and five survivors aged 17-40 years and 20 controls investigated on Days 2-5 of a menstrual cycle or Day 7 of an oral contraceptive pill-free interval. ovarian surface area (OS), total number of antral follicles (AFC), serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol and anti-Müllerian hormone (AMH). Survivors had a lower OS than controls: 3.5 versus 4.4 cm(2) per ovary (P = 0.0004), and lower AMH levels: 10.7 versus 22 pmol/l (P = 0.003). Ovarian markers (OS, AMH, AFC) were worse in patients who received high-dose compared with conventional-dose alkylating agents (P = 0.01 for OS, P = 0.002 for AMH, P < 0.0001 for AFC). Hodgkin lymphoma survivors seemed to have a greater reduction in ovarian reserve than survivors of leukaemia (P = 0.04 for AMH, P = 0.01 for AFC), sarcoma (P = 0.04 for AMH, P = 0.04 for AFC) and other lymphomas (P = 0.04 for AFC). A multiple linear regression analysis showed that procarbazine but not cyclophosphamide nor ifosfamide dose was associated with reduced OS (P = 0.0003), AFC (P = 0.0007), AMH (P < 0.0001) and higher FSH levels (P < 0.0001). The small percentage of participating survivors (28%) from the total cohort does not allow conclusion on fertility issues because of possible response bias. The association between procarbazine and HL makes it impossible to dissociate their individual impacts on ovarian reserve. The number of controls is small, but ovarian volume and AMH levels in survivors were compared with published normal values and results were unchanged. Early detection and follow-up of compromised ovarian function after cancer therapy should help physicians to counsel young survivors about their fertility window. However, longitudinal follow-up is required to determine the rate of progression from low ovarian reserve to premature ovarian failure. La Ligue contre le Cancer (grant no., PRAYN7497).

The management of Ewing's sarcoma family of tumors (ESFT, Ewing's sarcoma/primitive neuroectodermal tumor) has been established as a multimodality treatment. Advances in imaging and diagnostics, chemotherapy, surgical techniques, radiotherapy and prosthetic technology have resulted in drastic changes in the outcome of this disease, with most of the recent studies having 5-year survival rates of more than 60%. The Indian patients present at a more advanced stage and the compliance of treatment is suboptimal. While there is plenty of data in the world literature on the outcome of Ewing's sarcoma, there is paucity of data in Indian patients. Therefore, we conducted the present study to analyze the outcome of multimodality treatment of ESFT of the extremities at a tertiary nonprofit institute over a decade. 34 patients who had histopathologically proven diagnosis of Ewing's sarcoma of the extremities and had received treatment at our institute from 1997 through 2007 were included for analysis. The majority of patients had involvement of the femur (35%), followed by tibia (17%), fibula and foot (15% each), humerus (12%) and soft tissue of thigh (6%). Twenty-nine patients presented with localized disease (Enneking stage II B) while five patients presented with metastases (Enneking stage III). All patients received Vincristine, Actinomycin D, Cyclofosfamide + Ifosfamide and Etoposide (VAC+IE)-based chemotherapy and local treatment was offered to all but three patients having multicentric disease. The local treatment offered were, radiation (n= 15), surgery (n= 12) both surgery and radiation (n=4). All patients were analyzed for oncological outcome (event-free and overall survival, local and systemic relapses) by clinical and imaging evaluation and functional outcome by using the musculoskeletal tumor society (MSTS) score. These outcomes were correlated with age, sex, size of tumor, stage at presentation, modality of local treatment and site of relapse. At the final follow-up (mean, 26 months; median, 17 months; range, 3-97 months), the overall and event-free survivals were 47 ± 12% and 34 ± 9%, respectively. Sixty-two percent of the patients presented with a tumor size more than 8 cm. On correlation with age, sex, size of tumor, stage at presentation, modality of local treatment and site of relapse, no correlation of survival was seen with any of the variables except event-free survival with size of the tumor. The functional outcome of all the patients was satisfactory (MSTS score >16 out of 30). No patient underwent amputation. Although the demographic profile, stage at presentation and the local and systemic treatment regimen followed in our study was similar to the world literature, the outcome of Ewing's sarcoma in Indian patients were found to be inferior to that reported in the western literature. Larger multicentric studies with longer follow-up are required to exactly determine the key areas crucial in improving this outcome.

Occupational exposure to hazardous drugs can decrease fertility and result in miscarriages, stillbirths, and cancers in healthcare staff. Several recommended practices aim to reduce this exposure, including protective clothing, gloves, and biological safety cabinets ('safe handling'). There is significant uncertainty as to whether using closed-system drug-transfer devices (CSTD) in addition to safe handling decreases the contamination and risk of staff exposure to infusional hazardous drugs compared to safe handling alone. To assess the effects of closed-system drug-transfer of infusional hazardous drugs plus safe handling versus safe handling alone for reducing staff exposure to infusional hazardous drugs and risk of staff contamination. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, OSH-UPDATE, CINAHL, Science Citation Index Expanded, economic evaluation databases, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov to October 2017. We included comparative studies of any study design (irrespective of language, blinding, or publication status) that compared CSTD plus safe handling versus safe handling alone for infusional hazardous drugs. Two review authors independently identified trials and extracted data. We calculated the risk ratio (RR) and mean difference (MD) with 95% confidence intervals (CI) using both fixed-effect and random-effects models. We assessed risk of bias according to the risk of bias in non-randomised studies of interventions (ROBINS-I) tool, used an intracluster correlation coefficient of 0.10, and we assessed the quality of the evidence using GRADE. We included 23 observational cluster studies (358 hospitals) in this review. We did not find any randomised controlled trials or formal economic evaluations. In 21 studies, the people who used the intervention (CSTD plus safe handling) and control (safe handling alone) were pharmacists or pharmacy technicians; in the other two studies, the people who used the intervention and control were nurses, pharmacists, or pharmacy technicians. The CSTD used in the studies were PhaSeal (13 studies), Tevadaptor (1 study), SpikeSwan (1 study), PhaSeal and Tevadaptor (1 study), varied (5 studies), and not stated (2 studies). The studies' descriptions of the control groups were varied. Twenty-one studies provide data on one or more outcomes for this systematic review. All the studies are at serious risk of bias. The quality of evidence is very low for all the outcomes.There is no evidence of differences in the proportion of people with positive urine tests for exposure between the CSTD and control groups for cyclophosphamide alone (RR 0.83, 95% CI 0.46 to 1.52; I² = 12%; 2 studies; 2 hospitals; 20 participants; CSTD: 76.1% versus control: 91.7%); cyclophosphamide or ifosfamide (RR 0.09, 95% CI 0.00 to 2.79; 1 study; 1 hospital; 14 participants; CSTD: 6.4% versus control: 71.4%); and cyclophosphamide, ifosfamide, or gemcitabine (RR not estimable; 1 study; 1 hospital; 36 participants; 0% in both groups).There is no evidence of a difference in the proportion of surface samples contaminated in the pharmacy areas or patient-care areas for any of the drugs except 5-fluorouracil, which was lower in the CSTD group than in the control (RR 0.65, 95% CI 0.43 to 0.97; 3 studies, 106 hospitals, 1008 samples; CSTD: 9% versus control: 13.9%).The amount of cyclophosphamide was lower in pharmacy areas in the CSTD group than in the control group (MD -49.34 pg/cm², 95% CI -84.11 to -14.56, I² = 0%, 7 studies; 282 hospitals, 1793 surface samples). Additionally, one interrupted time-series study (3 hospitals; 342 samples) demonstrated a change in the slope between pre-CSTD and CSTD (3.9439 pg/cm², 95% CI 1.2303 to 6.6576; P = 0.010), but not between CSTD and post-CSTD withdrawal (-1.9331 pg/cm², 95% CI -5.1260 to 1.2598; P = 0.20). There is no evidence of difference in the amount of the other drugs between CSTD and control groups in the pharmacy areas or patient-care areas.None of the studies report on atmospheric contamination, blood tests, or other measures of exposure to infusional hazardous drugs such as urine mutagenicity, chromosomal aberrations, sister chromatid exchanges, or micronuclei induction.None of the studies report short-term health benefits such as reduction in skin rashes, medium-term reproductive health benefits such as fertility and parity, or long-term health benefits related to the development of any type of cancer or adverse events.Five studies (six hospitals) report the potential cost savings through the use of CSTD. The studies used different methods of calculating the costs, and the results were not reported in a format that could be pooled via meta-analysis. There is significant variability between the studies in terms of whether CSTD resulted in cost savings (the point estimates of the average potential cost savings ranged from (2017) USD -642,656 to (2017) USD 221,818). There is currently no evidence to support or refute the routine use of closed-system drug transfer devices in addition to safe handling of infusional hazardous drugs, as there is no evidence of differences in exposure or financial benefits between CSTD plus safe handling versus safe handling alone (very low-quality evidence). None of the studies report health benefits.Well-designed multicentre randomised controlled trials may be feasible depending upon the proportion of people with exposure. The next best study design is interrupted time-series. This design is likely to provide a better estimate than uncontrolled before-after studies or cross-sectional studies. Future studies may involve other alternate ways of reducing exposure in addition to safe handling as one intervention group in a multi-arm parallel design or factorial design trial. Future studies should have designs that decrease the risk of bias and enable measurement of direct health benefits in addition to exposure. Studies using exposure should be tested for a relevant selection of hazardous drugs used in the hospital to provide an estimate of the exposure and health benefits of using CSTD. Steps should be undertaken to ensure that there are no other differences between CSTD and control groups, so that one can obtain a reasonable estimate of the health benefits of using CSTD.

Poor prognosis germ-cell tumours are only cured in about half of patients. We aimed to assess whether treatment intensification based on an early tumour marker decline will improve progression-free survival for patients with germ-cell tumours. In this phase 3, multicentre, randomised trial, patients were enrolled from France (20 centres), USA (one centre), and Slovakia (one centre). Patients were eligible if they were older than 16 years, had evidence of testicular, retroperitoneal, or mediastinal non-seminomatous germ cell tumours based on histological findings or clinical evidence and highly elevated serum human chorionic gonadotropin or alfa-fetoprotein concentrations that matched International Germ Cell Cancer Consensus Group poor prognosis criteria. After one cycle of BEP (intravenous cisplatin [20 mg/m(2) per day for 5 days], etoposide [100 mg/m(2) per day for 5 days], and intramuscular or intravenous bleomycin [30 mg per day on days 1, 8, and 15]), patients' human chorionic gonadotropin and alfa-fetoprotein concentrations were measured at day 18-21. Patients with a favourable decline in human chorionic gonadotropin and alfa-fetoprotein continued BEP (Fav-BEP group) for 3 additonal cycles, whereas patients with an unfavourable decline were randomly assigned (1:1) to receive either BEP (Unfav-BEP group) or a dose-dense regimen (Unfav-dose-dense group), consisting of intravenous paclitaxel (175 mg/m(2) over 3 h on day 1) before BEP plus intravenous oxaliplatin (130 mg/m(2) over 3 h on day 10; two cycles), followed by intravenous cisplatin (100 mg/m(2) over 2 h on day 1), intravenous ifosfamide (2 g/m(2) over 3 h on days 10, 12, and 14), plus mesna (500 mg/m(2) at 0, 3, 7 and 11 h), and bleomycin (25 units per day, by continuous infusion for 5 days on days 10-14; two cycles), with granulocyte-colony stimulating factor (lenograstim) support. Centrally blocked computer-generated randomisation stratified by centre was used. The primary endpoint was progression-free survival and the efficacy analysis was done in the intention-to-treat population. The planned trial accrual was completed in May, 2012, and follow-up is ongoing. This study is registered with ClinicalTrials.gov, number NCT00104676. Between Nov 28, 2003, and May 16, 2012, 263 patients were enrolled and 254 were available for tumour marker assessment. Of these 51 (20%) had a favourable marker assessment, and 203 (80%) had an unfavourable tumour marker decline; 105 were randomly assigned to the Unfav-dose-dense group and 98 to the Unfav-BEP group. 3-year progression-free survival was 59% (95% CI 49-68) in the Unfav-dose-dense group versus 48% (38-59) in the Unfav-BEP group (HR 0·66, 95% CI 0·44-1·00, p=0·05). 3-year progression-free survival was 70% (95% CI 57-81) in the Fav-BEP group (HR 0·66, 95% CI 0·49-0·88, p=0·01 for progression-free survival compared with the Unfav-BEP group). More grade 3-4 neurotoxic events (seven [7%] vs one [1%]) and haematotoxic events occurred in the Unfav-dose-dense group compared with in the Unfav-BEP group; there was no difference in grade 1-2 febrile neutropenia (18 [17%] vs 18 [18%]) or toxic deaths (one [1%] in both groups). Salvage high-dose chemotherapy plus a stem-cell transplant was required in six (6%) patients in the Unfav-dose-dense group and 16 (16%) in the Unfav-BEP group. Personalised treatment with chemotherapy intensification reduces the risk of progression or death in patients with poor prognosis germ-cell tumours and an unfavourable tumour marker decline.
