RESUMO

BACKGROUND: Unresectable cholangiocarcinoma has a poor prognosis and treatment options are limited. Combined systemic and intrahepatic chemotherapy may improve local control and enable downsizing. The aim of this study was to determine the maximum tolerated dose (MTD) of intravenous gemcitabine combined with intravenous cisplatin and hepatic arterial infusion (HAI) with floxuridine (FUDR) in patients with unresectable intrahepatic or hilar cholangiocarcinoma. METHODS: Twelve patients were treated within a 3 + 3 dose escalation algorithm with 600, 800, or 1,000 mg/m2 gemcitabine and predefined doses of cisplatin 25 mg/m2 on days 1 and 8, q21, for 4 cycles, and FUDR 0.2 mg/kg on days 1-14 as continuous HAI, q28, for 3 cycles. Safety and toxicity as well as resectability rates after 3 months and preliminary survival data are reported. RESULTS: The determined MTD for gemcitabine was 800 mg/m2. Dose limiting toxicities were neutropenic fever and biliary tract infections. In total, 27% of the patients showed partial remission and 73% stable disease. Although none of the patients achieved resectability after 3 months, the 3-year overall survival rate was 33%, median overall survival 23.9 months (range 1-49), and median progression-free survival 10.1 months (range 2-40). CONCLUSIONS: Intravenous gemcitabine/cisplatin plus HAI-FUDR is feasible and appears effective for disease control. Larger prospective studies evaluating this triplet combination are warranted.

RESUMO

BACKGROUND: High rates of venous thromboembolic events (VTEs), mainly in advanced disease, are reported for patients with cancer of the upper gastrointestinal tract (stomach, pancreas) and for treatment with cisplatin. METHODS: Exploratory analysis of VTEs reported as adverse events and serious adverse events in a prospective, randomised, multicentre, multimodal phase III trial according to VTEs reported as adverse events and severe adverse events. Patients with resectable oesophageal cancer (T2N1-3, T3-4aNx) were randomized to 2 cycles of chemotherapy with docetaxel 75 mg/m2, cisplatin 75 mg/m2 followed by chemo-radiotherapy (CRT) and subsequent surgery (control arm) or the same treatment with addition of cetuximab (investigational arm). RESULTS: VTEs occurred in 26 of 300 patients included in the trial, resulting in an incidence rate (IR) of 8.7% [95% CI 5.7-12.4%]. A total of 29 VTEs were reported:13 (45%) VTEs were grade 2, 13 (45%) grade 3 and three (10%) fatal grade 5 events. 72% (21/29) of all VTEs occurred preoperatively (IR 6.7%): 14% (4/29) during chemotherapy and 59% (17/29) during CRT. In multivariable logistic regression only adenocarcinoma (IR 11.1%, 21/189 patients) compared to squamous cell cancer (IR 4.5%, 5/111 patients) was significantly associated with VTE-risk during treatment, OR 2.9 [95%CI 1.0-8.4], p = 0.046. Baseline Khorana risk score was 0 in 73% (19/26), 1-2 in 23% (6/26) and 3 in only 4% (1/26) of patients with VTEs. CONCLUSION: A high incidence of VTEs during preoperative therapy of resectable oesophageal cancer is observed in this analysis, especially in patients with adenocarcinoma. The role of prophylactic anticoagulation during neoadjuvant therapy in resectable esophageal cancer should be further evaluated in prospective clinical trials. According to our data, which are in line with other analysis of VTE-risk in patients with oesophageal cancer patients treated with neoadjuvant cisplatin-based chemotherapy and CRT, prophylactic anticoagluation could be considered balanced against individual bleeding risks, especially in patients with adenocarcinoma. In addition to the established risk factors, oesophageal adenocarcinoma treated with neoadjuvant cisplatin-based therapy may be regarded as a high-risk situation for VTEs. TRIAL REGISTRATION: Registered at clinicaltrials.gov, NCT01107639, on 21 April 2010.

RESUMO

Vinorelbine combined with filgrastim at a dose of 10 µg/kg of body weight (BW) per day is a reliable and well-tolerated regimen for mobilization of hematopoietic progenitor cells (HPCs) in patients with multiple myeloma. This prospective, randomized, phase II study was initiated to assess the feasibility of a reduced filgrastim dosage. Vinorelbine was combined with either standard-dose filgrastim (10 µg/kg BW per day) or reduced-dose filgrastim (5 µg/kg BW per day). Leukapheresis sessions were planned to start at day 8 and were continued until the predefined target amount of 4 × 106 HPCs/kg BW was collected. The study demonstrated the feasibility of vinorelbine combined with reduced daily filgrastim with a mean of 1.29 leukapheresis sessions necessary per patient (95% confidence interval, .95 to 1.7). All patients could start leukapheresis as planned at day 8, and the collection success rate was 100% for the whole patient collective after a maximum of 2 leukapheresis sessions. No statistically significant differences with regard to the amount of HPCs collected between the 2 groups were observed (P = .99). Accordingly, no differences were seen with regard to length of hospitalization for autotransplant (P = .34) and duration of neutrophil (P = .93) and platelet engraftment (P = .42). Patients receiving reduced-dose filgrastim reported significantly lower peak pain values in a numeric analogue scale (P = .01), and the costs were significantly lower than in patients undergoing standard-dose chemomobilization (P = .001). Vinorelbine 35 mg/m2 plus filgrastim 5 µg/kg BW once per day until completion of HPC collection is feasible and appears to be advantageous with respect to the severity of pain intensity and treatment costs.

RESUMO

BACKGROUND: Pathologic response to neoadjuvant chemotherapy (neoCTX) is a prognostic factor in many cancer types, and early prediction would help to modify treatment. In patients with gastric and esophagogastric junction (AEG) cancer, the accuracy of FDG PET-CT to predict early pathologic response after neoadjuvant chemotherapy (neoCTX) is currently not known. METHODS: From a consecutive cohort of 72 patients, 44 patients with resectable, locally-advanced gastric cancer or AEG Siewert type II and III received neoCTX after primary staging with endoscopic ultrasound, PET-CT and laparoscopy. Overall, 14 patients did not show FDG uptake, and the remaining 30 were restaged by PET-CT 14 days after the first cycle of neoCTX. Metabolic response was defined as decrease of tumor standardized uptake value (SUV) by ≥35%. Major pathologic regression was defined as less than 10% residual tumor cells. RESULTS: Metabolic response after neoCTX was detected in 20/30 (66.7%), and non-response in 10/30 (33.3%) patients. Among metabolic responders, n = 10 (50%) showed major and n = 10 (50%) minor pathologic regression. In non-responders, n = 9 (90%) had minor and 1 (10%) a major pathologic regression. This resulted in a sensitivity of 90.9%, specificity 47.3%, positive predictive value 50%, negative predictive value 90% and accuracy of 63.3%. CONCLUSION: Response PET-CT after the first cycle of neoCTX does not accurately predict overall pathologic response. However, PET-CT reliably detects non-responders, and identifies patients who should either immediately proceed to resection or receive a modified multimodality therapy. TRIAL REGISTRATION: The trial was registered and approved by local ethics committee PB_2016-00769.

RESUMO

BACKGROUND: Biliary tract cancer (BTC) is a dismal disease, even after curative intent surgery. We conducted this prospective, non-randomized phase II study to evaluate the feasibility and efficacy of cisplatin and gemcitabine as adjuvant treatment in patients with resected BTC. METHODS: Patients initially received gemcitabine 1000 mg/m2 alone on days 1, 8 and 15 every 28-days for a total of six cycles (single agent cohort), and after protocol amendment a combination therapy with gemcitabine 1000 mg/m2 and cisplatin 25 mg/m2 on days 1 and 8 was administered every 21 days for a total of eight cycles (combined regimen cohort). Treatment was planned to start within eight weeks after curative intent resection. Adverse events, disease-free survival and overall survival were assessed. RESULTS: Overall 30 patients were enrolled in the study from August 2008 and last patient was enrolled at 2nd December 2014. The follow-up of the patients ended at 31st December 2016. The first 9 patients received single-agent gemcitabine. The interim analysis met the predefined feasibility criteria and, from September 2010 on, the second group of 21 patients received the combination of cisplatin plus gemcitabine. In the single-agent cohort with gemcitabine the median relative dose intensity (RDI) was 100% (IQR 88.3-100). Patients treated with the combination cisplatin-gemcitabine received an overall median RDI of 100% (IQR 50-100) for cisplatin and 100% (IQR 75-100) for gemcitabine respectively. The most significant non-hematological adverse events (grade 3 or 4) were fatigue (20%), infections during neutropenia (10%), and two cases of biliary sepsis (7%). Abnormal liver function was seen in 10% of the patients. One patient died due to infectious complications during treatment with cisplatin and gemcitabine. The median disease-free survival (DFS) was 14.9 months (95% CI 0-33.8) with a corresponding 3-year DFS of 43.1 ± 9.1%. The median overall survival (OS) was 40.6 months (95% CI 18.8-62.3) with a 3-year OS of 55.7 ± 9.2%. No statistically significant differences in survival were seen between the two treatment cohorts. CONCLUSION: Adjuvant chemotherapy with gemcitabine with or without cisplatin was well tolerated and resulted in promising survival of the patients. TRIAL REGISTRATION: The study was retrospectively registered on 25th June 2009 at clinicaltrials.gov ( NCT01073839 ).

RESUMO

Standard of care for untreated mantle cell lymphoma (MCL) is still debated. At the University Hospital Zurich, advanced MCL in physically fit patients is treated either with rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone induction followed by consolidating high-dose chemotherapy and autologous stem cell support (R-CHOP/HD-ASCT), or with rituximab plus fractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone alternating with high-dose methotrexate-cytarabine (R-hyper-CVAD/MTX-AraC) without consolidating HD-ASCT upon physicians' and patients' choice. We retrospectively analysed the outcome and therapy tolerance in patients with MCL treated with R-CHOP/HD-ASCT or R-hyper-CVAD/MTX-AraC at the University Hospital Zurich between January 1996 and January 2016. Forty-three patients were included; 29 patients received R-CHOP/HD-ASCT and 14 patients R-hyper-CVAD/MTX-AraC. Mean age at diagnosis was 54.4 years (range 38-68 years). Thirty-five patients (81.4%) completed the entire first-line therapy (n = 24 in the R-CHOP/HD-ASCT group, n = 11 in the R-hyper-CVAD group). Of those, all patients responded and 97% achieved a complete remission (CR). With a mean follow-up of 5.7 years 10-year progression-free survival (PFS) for all patients was 32% and overall survival (OS) was 76%, with no difference between the two therapy groups. Complication-induced hospitalisation rate, haematological toxicity and economic burden were significantly higher in the R-hyper-CVAD therapy group. In contrast, quality of life and global health state were better in the R-hyper-CVAD therapy group. Both first-line therapies showed similar outcome with a median OS longer than 10 years. Due to significantly lower haematological toxicity and lower economic burden, we recommend R-CHOP/HD-ASCT as first-line therapy in fit adult patients with advanced MCL.

RESUMO

Biosimilars are increasingly being licensed as equipotent drugs, although efficacy and safety data are not available for all clinical indications. Accordingly, the efficacy of the biosimilar filgrastim Zarzio® combined with vinorelbine for chemo-mobilization of CD34+ hematopoietic progenitor cells (HPC) in patients with multiple myeloma has not been evaluated yet. We compared the efficacy of vinorelbine combined with this biosimilar filgrastim for HPC mobilization to vinorelbine plus original filgrastim (Neupogen®). Overall, 105 multiple myeloma patients received vinorelbine 35 mg/m2 intravenously on day 1 and either original filgrastim (n = 61;58%) or biosimilar filgrastim (n = 44;42%) at a dose of 5 µg per kg body weight (BW) twice daily subcutaneously starting day 4 until the end of the collection procedure. Leukapheresis was scheduled to start on day 8 and performed for a maximum of three consecutive days until at least 4 × 106 HPC/kg BW were collected. All patients proceeded to leukapheresis. In 102 (97%) patients the leukapheresis sessions were started as planned at day 8. The median number of collected HPC was 7.3 × 106 /kg BW (0.2-18.3) with original filgrastim compared to 9 × 106 /kg BW (4.2-23.8) with the biosimilar filgrastim (P = 0.16). HPC collection was successful in 57 (93%) of 61 patients of the original group and in all 44 (100%) patients of the biosimilar group (P = 0.14). No differences were observed regarding side effects. Duration of neutrophil engraftment after autologous HPC transplantation was similar between the two groups (P = 0.17). Biosimilar and original filgrastim achieve comparable results in combination with vinorelbine regarding HPC mobilization and transplantation outcome in multiple myeloma patients. J. Clin.

RESUMO

An increasing number of older patients are suffering from aggressive lymphoma. Effective and more tolerable treatment regimens are urgently needed for this growing patient population. Patients with aggressive lymphoma not eligible for anthracycline-based first-line therapy or intensive salvage regimens were treated with the rituximab-bendamustine-lenalidomide (R-BL) regimen (rituximab 375 mg/m(2)  day 1, bendamustine 70 mg/m(2)  d 1, 2, lenalidomide 10 mg d 1-21) for six cycles every 4 weeks. Forty-one patients with a median age of 75 (range 40-94) years were enrolled: 33 patients had substantial co-morbidities. 13 patients were not eligible for anthracycline-based first-line chemotherapy, 28 patients had relapsed/refractory disease. The primary endpoint, overall response, was achieved by 25 (61%) patients (95% confidence interval 45-76%). Grade ≥ 3 toxicity comprised haematological (59%), skin (15%), constitutional (15%) and neurological (12%) events. 9 patients died during trial treatment: 5 from lymphoma progression, 2 from toxicity, 2 with sudden death. After a median follow-up of 25·9 (interquartile range 20·4-31·6) months, 13 patients were still alive. Median overall survival was 14·5 months. In conclusion, R-BL can be considered a treatment option for elderly patients with treatment naïve or relapsed/refractory aggressive lymphoma not eligible for standard aggressive regimens.

RESUMO

BACKGROUND: Solid tumors, such as hepato-pancreato-biliary cancer, develop tumor hypoxia with tumor growth. Despite advances in surgery, a majority of these patients are in an unresectable condition. At this stage standard cytotoxic chemotherapy regimens are applied with limited success. Novel biological treatment options based on an antiangiogenic mechanism of action neglect other hypoxia mediated mechanisms (e.g. epithelial-mesenchymal transition, Warburg effect, and immunological response) leading to an increased invasiveness with a poor outcome. The novel antihypoxic molecule myo-inositoltrispyrophosphate (ITPP, OXY111A) acts as an allosteric effector of hemoglobin and promotes normoxia in hypoxic tumors. In preclinical studies, tumor growth was reduced and survival prolonged. Additionally, a beneficial side effect profile was observed. METHODS: In this first Ib/IIa clinical trial we will assess safety and tolerability of OXY111A as well as a proof of concept regarding efficacy in patients with non-resectable primary and secondary tumors of the liver, pancreas, and biliary tract. The study design is exploratory, prospective, open-labelled and mono-centric. The study is divided in a dose escalation part with a maximum of 48 subjects and an extension part, in which 21 subjects will be included. DISCUSSION: The novel antihypoxic compound OXY111A has been tested in several cancer animal models showing beneficial effects for both survival and low side effect profiles. This first in patient application of OXY111A will reveal potential beneficial outcomes if anti-hypoxic therapy is added to standard cytotoxic treatment in patients with primary and secondary hepatopancreatobiliary tumors.

RESUMO

BACKGROUND: Gastrointestinal and extraintestinal malignancies are long-term complications in patients with inflammatory bowel disease (IBD), likely as a result of chronic inflammation and the use of immunosuppressive medications used to control inflammation. Here, we assessed the frequency of malignancies in a large tertiary IBD centre at the University Hospital Zurich. METHODS: We performed a retrospective analysis of data from 1,026 patients from our IBD clinic treated between 2007 and 2014. RESULTS: Twenty two of the 1,026 patients developed 28 cases of malignancies, 14 patients were male and 8 patients female. The median latency between IBD diagnosis and first malignancy was 13 years (range 2-27 years). Most common malignancies were non-Hodgkin lymphoma, colorectal cancer (CRC), urothelial carcinoma, cholangiocellular carcinoma (CCC) and prostate cancer. The most common tumour type in Crohn's disease patients (13/22) was lymphoma (5 cases), in ulcerative colitis patients (9/22) CCC (2 cases) and CRC (2 cases). The observed incidence of lymphoma (32.5/100,000), bladder carcinoma (21.7/100,000) and CCC (10.8/100,000) was higher than expected and known from general population. All of the patients that developed a malignancy had received immunosuppressive therapy. Compared to a cohort of 927 IBD patients without malignancies there were no statistical differences regarding gender, antibodies targeting tumour necrosis factor and thiopurine use. CONCLUSION: Our data support the assumption that a long-standing disease course and immunosuppressive therapy increase the risk for developing malignancies in IBD patients.

RESUMO

We aimed to assess the efficacy of vinorelbine plus granulocyte colony-stimulating factor (G-CSF) for chemo-mobilization of CD34(+) hematopoietic progenitor cells (HPC) in patients with multiple myeloma and to identify adverse risk factors for successful mobilization. Vinorelbine 35 mg/m(2) was administered intravenously on day 1 in an outpatient setting. Filgrastim 5 µg/kg body weight (BW) was given twice daily subcutaneously from day 4 until the end of the collection procedure. Leukapheresis was scheduled to start on day 8 and be performed for a maximum of 3 consecutive days until at least 4 × 10(6) CD34(+) cells per kg BW were collected. Overall, 223 patients were mobilized and 221 (99%) patients proceeded to leukapheresis. Three (1.5%) patients required an unscheduled hospitalization after chemo-mobilization because of neutropenic fever and renal failure (n = 1), severe bone pain (n = 1), and abdominal pain with constipation (n = 1). In 211 (95%) patients, the leukaphereses were started as planned at day 8, whereas in 8 (3%) patients the procedure was postponed to day 9 and in 2 (1%) patients to day 10. In the great majority of patients (77%), the predefined amount of HPC could be collected with 1 leukapheresis. Forty-four (20%) patients needed a second leukapheresis, whereas only 6 (3%) patients required a third leukapheresis procedure. The median number of CD34(+) cells collected was 6.56 × 10(6) (range, .18 to 25.9 × 10(6)) per kg BW at the first day of leukapheresis and 7.65 × 10(6) (range, .18 to 25.9 × 10(6)) per kg BW in total. HPC collection was successful in 212 (95%) patients after a maximum of 3 leukaphereses. Patient age (P = .02) and prior exposition to lenalidomide (P < .001) were independent risk factors for a lower HPC amount collected in multiple regression analysis. Vinorelbine plus G-CSF enables a very reliable prediction of the timing of leukapheresis and results in successful HPC collection in 95% of the patients.

RESUMO

Background: Replacement of carmustine (BCNU) in the BEAM regimen (BCNU, etoposide, cytarabine, melphalan) with bendamustine (BendaEAM) before autologous stem cell transplantation (ASCT) is feasible in lymphoma. However, randomised trials are lacking. Here, we present the first trial addressing this topic. Methods: This multicentre, randomised, phase 2 study (BEB-trial) conducted at four haematological centres in Austria and Switzerland compares BEAM with BendaEAM in patients with relapsed lymphoma. Both regimens were administered intravenously before ASCT, in BEAM according to the standard protocol (300 mg/m2 BCNU on day -6), in BendaEAM, BCNU was replaced by 200 mg/m2 bendamustine given on days -7 and -6. Eligible patients were aged 18-75 years and had mantle cell lymphoma, diffuse large B-cell lymphoma, or follicular lymphoma in first or second remission or chemosensitive relapse. The primary endpoint of the study was to evaluate whether replacement of BCNU by bendamustine reduces lung toxicity, defined as a decrease of the diffusion capacity of the lung for carbon monoxide by at least 20% at three months after ASCT. Data analyses were performed on an intention-to-treat basis. This study is registered with ClinicalTrials.gov, number NCT02278796, and is complete. Findings: Between April 20, 2015, and November 28, 2018, 108 patients were enrolled; of whom 53 were randomly assigned to receive BendaEAM (36 male, 17 female) and 55 to receive BEAM (39 male, 16 female). All patients engrafted rapidly. Lung toxicity did not differ between groups (BendaEAM: n = 8, 19.5%; BEAM: n = 11, 25.6%; risk difference = -6.1%: 95% confidence interval: -23.9% to 11.7%). Acute toxicities of at least grade 3 were comparable in both groups (BendaEAM: 35.8%, BEAM: 30.9%). Overall survival (BendaEAM: 92.5%, BEAM: 89.1%) and complete remission (BendaEAM: 76.7%, BEAM: 74.3%) after 1 year (median follow-up: 369 days) were similar. No difference in quality of life was observed. Interpretation: Results were similar for both regimens in terms of survival and response rates. A phase 3 non-inferiority study is required to investigate whether BendaEAM can be considered as an alternative to BEAM. Funding: Mundipharma.

RESUMO

OBJECTIVE: To evaluate the optimal sequence for the receptor tyrosine kinase inhibitors (rTKIs) sorafenib and sunitinib in metastatic renal cell cancer. METHODS: We performed a retrospective analysis of patients who had received sequential therapy with both rTKIs and integrated these results into a pooled analysis of available data from other publications. Differences in median progression-free survival (PFS) for first- (PFS1) and second-line treatment (PFS2), and for the combined PFS (PFS1 plus PFS2) were examined using weighted linear regression. RESULTS: In the pooled analysis encompassing 853 patients, the median combined PFS for first-line sunitinib and 2nd-line sorafenib (SuSo) was 12.1 months compared with 15.4 months for the reverse sequence (SoSu; 95% CI for difference 1.45-5.12, p = 0.0013). Regarding first-line treatment, no significant difference in PFS1 was noted regardless of which drug was initially used (0.62 months average increase on sorafenib, 95% CI for difference -1.01 to 2.26, p = 0.43). In second-line treatment, sunitinib showed a significantly longer PFS2 than sorafenib (average increase 2.66 months, 95% CI 1.02-4.3, p = 0.003). CONCLUSION: The SoSu sequence translates into a longer combined PFS compared to the SuSo sequence. Predominantly the superiority of sunitinib regarding PFS2 contributed to the longer combined PFS in sequential use.

RESUMO

OBJECTIVES: To investigate physiotherapists' current knowledge and practice in the management of patients with lateral elbow tendinopathy, to explore associations between the participants' education and management preferences and to identify potential evidence-to-practice gaps by making comparisons with recent research recommendations. DESIGN: An on-line cross-sectional survey. SUBJECTS: Registered physiotherapists working in Greece with previous experience in the management of lateral elbow tendinopathy. RESULTS: Three hundred and seventy eight responses met the inclusion criteria. Most responders (70.4%-91.5%) use pain provocation tests for the diagnosis of the condition, while a limited proportion uses patient rated outcome measures (6.9%-13%). Supervised exercise is the mainstay of rehabilitation (92.6%), followed by adjunctive research recommended treatment techniques such as manual therapy (72%) and advice (59.5%). Up to 83.6% of participants use adjunctive treatment techniques that are not recommended or without research recommendation (such as electrophysical agents, ice etc.). Physiotherapists with post-graduate education in musculoskeletal physiotherapy are almost three times more likely to choose only research recommended treatment approaches. There is a lack of consensus in an optimal exercise programme (type, volume, duration etc.) in patients with lateral elbow tendinopathy. CONCLUSION: Despite research recommendations a limited use of patient rated outcome measures in lateral elbow tendinopathy is recorded. Supervised exercise is the first line treatment option for most physiotherapists, although the optimal application is still unclear. A large proportion of physiotherapists apply adjunctive treatment techniques that are either ineffective or poorly researched suggesting a substantial evidence-to-practice gap. Better access to knowledge, organisational and peer-support can potentially help to bridge this gap.

RESUMO

Particle-mediated epidermal delivery (PMED) is a potent genetic vaccination method. However, a recent report found PMED only poorly and infrequently triggered antigen-specific cytotoxic T-cells in cancer patients. Here, we show that injection of the chemotherapeutic drug Gemcitabine in mice results in improvement of the efficacy of subsequent PMED vaccination against NY-ESO-1. We found in mice and in cancer patients that administration of Gemcitabine induces a transient reduction in the percentage of regulatory T-cells among CD4-positive cells. The higher relative sensitivity of regulatory T-cells compared to other CD4-positive T-cells toward cytostatic drugs can be linked to the higher frequency of proliferating cells in the regulatory compartment compared to the nonregulatory CD4-compartment in healthy people and cancer patients. Thus, by affecting regulatory T-cells more than other lymphocyte subsets, chemotherapeutic agents can create a transient hyperimmunoreactive window. Such a window would provide an ideal timepoint to administer a vaccine expected to induce a therapeutically relevant anticancer cytotoxic T-cell response.

RESUMO

BACKGROUND: An outcome assessment was performed of patients with unresectable colorectal liver metastases (CRLM) treated in second or third line with floxuridine (FUDR)-based hepatic artery infusion (HAI). METHODS: Twenty-three patients who were pretreated with systemic (immuno)chemotherapy received FUDR-HAI alone or combined with systemic chemotherapy. We reviewed patient charts and our prospective patient database for survival and associated risk factors. RESULTS: Patients received FUDR-HAI for unresectable CRLM from January 2000 to September 2010. Twelve patients (52%) received concurrent systemic chemotherapy. Median overall survival (OS), progression-free survival (PFS), and hepatic PFS were 15.6 months (range, 2.5-55.7 months), 3.9 months (range, 0.7-55.7 months), and 5.5 months (range, 1.6-55.7 months), respectively. The liver resection rate after HAI was 35%. PFS was better in patients undergoing secondary resection than in patients without resection (hazard ratio [HR] 0.21; 95% confidence interval [95% CI] 0.07-0.66; P = 0.0034), while OS showed a trend toward improvement (HR 0.4; 95% CI 0.13-1.2; P = 0.09). No differences were observed in OS (P = 0.69) or PFS (P = 0.086) in patients who received FUDR-HAI alone compared with patients treated with combined regional and systemic chemotherapy. No statistically significant differences were seen in patients previously treated with one chemotherapy line compared with patients treated with two lines. Presence of extrahepatic disease was a negative risk factor for PFS (liver-only disease: HR 0.03; 95% CI 0.0032-0.28; P < 0.0001). Toxicities were manageable with dose modifications and supportive measures. CONCLUSIONS: FUDR-HAI improves PFS and results in a trend toward improved OS in selected patients able to undergo liver resection after tumor is downsized.

RESUMO

To reduce the duration of neutropenia after conditioning chemotherapy and autologous peripheral blood stem cell transplantation (APBSCT), granulocyte-colony stimulating factors (G-CSF) are commonly administered. We retrospectively evaluated the impact of pegfilgrastim compared to filgrastim on neutrophil engraftment, hospital stay, and supportive measures in patients with multiple myeloma after conditioning with Melphalan 200 (Mel200) followed by APBSCT. Ninety-two APBSCT after Mel200 treatment were performed in 72 patients between January 2006 and December 2009 at our institution. Patients received either single-dose pegfilgrastim (n = 46; 50%), or daily filgrastim (n = 46; 50%) after APBSCT (median duration of filgrastim use, 9 days; range, 3-14 days). Duration of neutropenia grade IV was shorter with pegfilgrastim compared with filgrastim (median, 5 days (range, 3-14 days) versus 6 days (range, 3-9 days), p = 0.0079). The length of hospitalization differed significantly (pegfilgrastim (median, 14.5 days; range, 11-47 days) versus filgrastim (median, 15.5 days; range, 12-64 days), p = 0.024). Pegfilgrastim-treated patients had less red blood cell transfusions (median, 0 transfusions (range, 0-10) versus 0.5 transfusions (range, 0-9), p = 0.00065). Pegfilgrastim was associated with reduced cost of the treatment procedure compared with filgrastim (p = 0.031). Pegfilgrastim appears to be at least equivalent to filgrastim without additional expenditure in myeloma patients treated with Mel200 and APBSCT.

RESUMO

Hypoxia is prominent in solid tumors and a recognized driver of malignancy. Thus far, targeting tumor hypoxia has remained unsuccessful. Myo-inositol trispyrophosphate (ITPP) is a re-oxygenating compound without apparent toxicity. In preclinical models, ITPP potentiates the efficacy of subsequent chemotherapy through vascular normalization. Here, we report the results of an unrandomized, open-labeled, 3 + 3 dose-escalation phase Ib study (NCT02528526) including 28 patients with advanced primary hepatopancreatobiliary malignancies and liver metastases of colorectal cancer receiving nine 8h-infusions of ITPP over three weeks across eight dose levels (1'866-14'500 mg/m2/dose), followed by standard chemotherapy. Primary objectives are assessment of the safety and tolerability and establishment of the maximum tolerated dose, while secondary objectives include assessment of pharmacokinetics, antitumor activity via radiological evaluation and assessment of circulatory tumor-specific and angiogenic markers. The maximum tolerated dose is 12,390 mg/m2, and ITPP treatment results in 32 treatment-related toxicities (mostly hypercalcemia) that require little or no intervention. 52% of patients have morphological disease stabilization under ITPP monotherapy. Following subsequent chemotherapy, 10% show partial responses while 60% have stable disease. Decreases in angiogenic markers are noted in ∼60% of patients after ITPP and tend to correlate with responses and survival after chemotherapy.

RESUMO

BACKGROUND: Sunitinib (SU) is a multitargeted tyrosine kinase inhibitor with antitumor and antiangiogenic activity. The objective of this trial was to demonstrate antitumor activity of continuous SU treatment in patients with hepatocellular carcinoma (HCC). PATIENTS AND METHODS: Key eligibility criteria included unresectable or metastatic HCC, no prior systemic anticancer treatment, measurable disease, and Child-Pugh class A or mild Child-Pugh class B liver dysfunction. Patients received 37.5 mg SU daily until progression or unacceptable toxicity. The primary endpoint was progression-free survival at 12 weeks (PFS12). RESULTS: Forty-five patients were enrolled. The median age was 63 years; 89% had Child-Pugh class A disease and 47% had distant metastases. PFS12 was rated successful in 15 patients (33%; 95% confidence interval, 20%-47%). Over the whole trial period, one complete response and a 40% rate of stable disease as the best response were achieved. The median PFS duration, disease stabilization duration, time to progression, and overall survival time were 1.5, 2.9, 1.5, and 9.3 months, respectively. Grade 3 and 4 adverse events were infrequent. None of the 33 deaths were considered drug related. CONCLUSION: Continuous SU treatment with 37.5 mg daily is feasible and has moderate activity in patients with advanced HCC and mild to moderately impaired liver dysfunction. Under this trial design (>13 PFS12 successes), the therapy is considered promising. This is the first trial describing the clinical effects of continuous dosing of SU in HCC patients on a schedule that is used in an ongoing, randomized, phase III trial in comparison with the current treatment standard, sorafenib (ClinicalTrials.gov identifier, NCT00699374).
