Background: Most patients with cancers of the nasal cavity or paranasal sinuses are candidates of radiation therapy either due incomplete resection or technical inoperability. Local control in this disease is dose dependent but technically challenging due to close proximity of critical organs and accompanying toxicity. Modern techniques such as IMRT improve toxicity rates while local control remains unchanged. Raster-scanned carbon ion therapy with highly conformal dose distributions may allow higher doses at comparable or reduced side-effects.Methods/design: The IMRT-HIT-SNT trial is a prospective, mono-centric, phase II trial evaluating toxicity (primary endpoint: mucositis ≥ CTCAE°III) and efficacy (secondary endpoint: local control, disease-free and overall survival) in the combined treatment with IMRT and carbon ion boost in 30 patients with histologically proven (≥R1-resected or inoperable) adeno-/or squamous cell carcinoma of the nasal cavity or paransal sinuses. Patients receive 24 GyE carbon ions (8 fractions) and IMRT (50 Gy at 2.0 Gy/fraction).Discussion: The primary objective of IMRT-HIT-SNT is to evaluate toxicity and feasibility of the proposed treatment in sinonasal malignancies.Trial Registration: Clinical trial identifier NCT 01220752. © 2011 Jensen et al; licensee BioMed Central Ltd.


Background: Long-term locoregional control in locally advanced squamous cell carcinoma of the head and neck (SCCHN) remains challenging. While recent years have seen various approaches to improve outcome by intensification of treatment schedules through introduction of novel induction and combination chemotherapy regimen and altered fractionation regimen, patient tolerance to higher treatment intensities is limited by accompanying side-effects. Combined radioimmunotherapy with cetuximab as well as modern radiotherapy techniques such as intensity-modulated radiotherapy (IMRT) and carbon ion therapy (C12) are able to limit toxicity while maintaining treatment effects. In order to achieve maximum efficacy with yet acceptable toxicity, this sequential phase II trial combines induction chemotherapy with docetaxel, cisplatin, and 5-FU (TPF) followed by radioimmunotherapy with cetuximab as IMRT plus carbon ion boost. We expect this approach to result in increased cure rates with yet manageable accompanying toxicity.Methods/design: The TPF-C-HIT trial is a prospective, mono-centric, open-label, non-randomized phase II trial evaluating efficacy and toxicity of the combined treatment with IMRT/carbon ion boost and weekly cetuximab in 50 patients with histologically proven locally advanced SCCHN following TPF induction chemotherapy. Patients receive 24 GyE carbon ions (8 fractions) and 50 Gy IMRT (2.0 Gy/fraction) in combination with weekly cetuximab throughout radiotherapy. Primary endpoint is locoregional control at 12 months, secondary endpoints are disease-free survival, progression-free survival, overall survival, acute and late radiation effects as well as any adverse events of the treatment as well as quality of life (QoL) analyses.Discussion: The primary objective of TPF-C-HIT is to evaluate efficacy and toxicity of cetuximab in combination with combined IMRT/carbon ion therapy following TPF induction in locally advanced SCCHN.Trial Registration: Clinical Trial Identifier: NCT01245985 (clinicaltrials.gov).

Background: Compliance and persistence are often overlooked in adjuvant breast cancer treatment. Patients and methods: PACT was a prospective, multicenter, randomized, open, parallel-group study assessing whether educational materials (EMs) enhanced compliance with aromatase inhibitor (AI) therapy in postmenopausal women with early, hormone-receptor-positive (HR+) breast cancer. The primary end points were compliance (proportion taking ≥80% anastrozole) at 12 months and persistence (proportion reporting anastrozole intake during the study period). Results: Four thousand eight hundred and forty-four patients were randomly assigned 1:1 to receive standard therapy or standard therapy with EMs. There was no difference between arms in compliance (N = 2740; 88.5%/88.8%, respectively, P = 0.81) or persistence rates (N = 2740; 40.5%/43.0%, respectively, P = 0.18). Modified end point analyses found no differences in compliance between arms based on the classification of: (i) patients with missing documentation or follow-up visit <9 months as non-compliant (N = 4397, P = 0.15); (ii) patients with early (=292 days) 12-month follow-up documentation excluded (N = 4091, P = 0.19); (iii) patients reaching ≥80% compliance during individual follow-up as compliant (N = 4397, P = 0.26). Modified persistence analyses found no difference between arms (N = 4397, P = 0.37). Conclusions: Addition of EMs to standard therapy did not significantly affect compliance and persistence with adjuvant anastrozole.

Background: Local control in malignant salivary gland tumours is dose dependent. High local control rates in adenoid cystic carcinomas could be achieved by highly conformal radiotherapy techniques and particle (neutron/carbon ion) therapy. Considering high doses are needed to achieve local control, all malignant salivary gland tumours probably profit from the use of particle therapy, which in case of carbon ion treatment, has been shown to be accompanied by only mild side-effects.Methods/design: The COSMIC trial is a prospective, mono-centric, phase II trial evaluating toxicity (primary endpoint: mucositis ≥ CTCAE°3) and efficacy (secondary endpoint: local control, disease-free survival) in the combined treatment with IMRT and carbon ion boost in 54 patients with histologically proved (≥R1-resected, inoperable or Pn+) salivary gland malignancies. Patients receive 24 GyE carbon ions (8 fractions) and IMRT (50 Gy at 2.0 Gy/fraction).Discussion: The primary objective of COSMIC is to evaluate toxicity and feasibility of the proposed treatment in all salivary gland malignancies. © 2010 Jensen et al; licensee BioMed Central Ltd.

Background: Docetaxel is a widely used cytotoxic agent. This study evaluates the impact of docetaxel toxicities on patient's health-related quality of life (QoL). Patients and methods: We conducted a multicenter, prospective, non-interventional trial, in which the QoL was assessed using the EORTC QLQ-C30 questionnaires at baseline and every 4 weeks up to 40 weeks in patients receiving a docetaxel-based chemotherapy for metastatic disease. Treatment-related adverse events were correlated with the corresponding QoL scores. Uni-and multivariate analyses were applied. Results: From January 2008 to June 2011, a total of 2659 patients were included. The majority of patients (48.1%) had prostate cancer, followed by breast (17.1%) and non-small-cell-lung cancer (15.8%). Patients received a median of 5 docetaxel cycles with the median dose of 75 mg/m2. The presence of grade 3/4 diarrhea showed the strongest effect on global health status/QoL average scores (50.91 versus 33.06), followed by vomiting (50.91 versus 35.17), dyspnea (50.94 versus 35.81), mucositis/stomatitis (50.88 versus 36.41), nausea (50.91 versus 36.68), infection (50.90 versus 37.14), fatigue (50.90 versus 43.82) and anemia (50.91 versus 41.03), P < 0.05 for all comparisons. Grade 3/4 leukopenia/neutropenia, alopecia, constipation, neurotoxicity and nail disorders had no significant impact on the global health status/QoL or other items. Conclusion: In this large non-interventional trial, docetaxel-associated grade 3 or 4 toxicities were shown to have a strong detrimental effect on patient's QoL. Notably, diarrhea and vomiting had the strongest negative impact on QoL measures. This has to be kept in mind while making therapeutic decisions and providing optimized supportive treatment measures.

Purpose: Very few reliable clinical data about the use of radioimmunotherapy in aggressive B-cell lymphoma exist. Methods: Patients with aggressive B-cell lymphoma registered in the international RIT-Network were analysed with regard to prior treatment, response and side effects. The RIT-Network is a web-based registry that collects observational data from radioimmunotherapy-treated patients with malignant lymphoma across 13 countries. Results: This analysis included 215 with aggressive B-cell lymphoma out of 232 patients registered in the RIT-Network. Histological subtypes were as follows: 190 diffuse large B-cell, 15 primary mediastinal, 9 anaplastic large cell, and 1 intravascular lymphoma. The median age of the patients was 62 years (range 17 - 88), with 27 % above the age of 70 years. Radioimmunotherapy was mainly used as consolidation after first-line or second-line chemotherapy (56.1 %), as part of third-line to eighth-line therapy for relapse (16.4 %), and in refractory disease (12.2 %). Grade IV neutropenia and thrombopenia and grade III anaemia were observed. The median time to recovery of blood count was 81 days (range 0 - 600 days). The overall response rate was 63.3 %. The complete response rate was 76.4 % in patients treated as part of first-line therapy, and 44.3 % in patients with relapse. Mean overall survival in first-line therapy patients was 32.7 months and 14.0 months in patients with relapse or refractory disease, respectively. Conclusion: Most patients with aggressive B-cell lymphoma in the RIT-Network received radioimmunotherapy as consolidation after first-line therapy with excellent complete remission and overall survival rates compared to published data. In relapsed aggressive B-cell lymphoma, radioimmunotherapy is a safe and feasible treatment leading to satisfactory response rates with acceptable toxicity. © 2014 Springer-Verlag.

Background: The prognosis of patients with recurrent, platinum-resistant epithelial ovarian cancer (EOC) is poor. There is no standard treatment available. Emerging evidence suggests a major role for antiangiogenic treatment modalities in EOC, in particular in combination with the metronomic application of low dose chemotherapy. The novel, investigational oral antiangiogenic agent pazopanib targeting vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR) and c-kit is currently being studied in different tumour types and is already used as first line therapy in recurrent renal cell carcinoma. A combined therapy consisting of pazopanib and metronomic oral cyclophosphamide may offer a well-tolerable treatment option to patients with recurrent, pretreated EOC.Methods/design: This study is designed as a multicenter phase I/II trial evaluating the optimal dose for pazopanib (phase I) as well as activity and tolerability of a combination regimen consisting of pazopanib and metronomic cyclophosphamide in the palliative treatment of patients with recurrent, platinum-resistant, pre-treated ovarian cancer (phase II). The patient population includes patients with histologically or cytologically confirmed diagnosis of EOC, cancer of the fallopian tube or peritoneal cancer which is platinumresistant or -refractory. Patients must have measurable disease according to RECIST criteria and must have failed available standard chemotherapy. Primary objectives are determination of the optimal doses for pazopanib (phase I) and the overall response rate according to RECIST criteria (phase II). Secondary objectives are time to progression, overall survival, safety and tolerability. The treatment duration is until disease progression or intolerability of study drug regimen (with a maximum of 13 cycles up to 52 weeks per subject).Discussion: The current phase I/II trial shall clarify the potential of the multitargeting antiangiogenic tyrosinkinaseinhibitor GW 786034 (pazopanib) in combination with oral cyclophosphamide as salvage treatment in patients with recurrent, pretreated ovarian cancer.Trial registration: ClinicalTrials.gov: NCT01238770. © 2011 Eichbaum et al; licensee BioMed Central Ltd.

About 75% of advanced epithelial ovarian cancer (EOC) patients respond to first-line surgery and chemotherapy but most relapse and ultimately acquire platinum resistance which soon leads to death. Relapsed high grade serous ovarian cancer (HGSOC) is the single main cause of EOC-related morbidity and mortality (despite the fact that HGSOC is highly chemosensitive). We hypothesize that the primary tumour includes a small population of resistant cells that are ultimately responsible for relapse and that by targeting this population front-line we may prolong disease-free survival or even achieve cure. OCTIPS will use unique retrospective and novel prospective paired tumour samples collected at the time of diagnosis and relapse to identify and validate molecules and pathways responsible for relapse. This identification will employ cutting edge high throughput multiplatform analyses such as next generation sequencing, mRNA and miRNA expression arrays and SNP array. Known and newly defined molecules or pathways will be evaluated in innovative integrated cancer model systems, utilising cell lines and avian egg and murine xenografts. New therapies to target these molecules and pathways will be developed and validated in these model systems. In order to translate these findings into patient benefit, agents that target the relapsing cell population will be tested for tolerability, efficacy, ability to combine with first line chemotherapy and then in randomised first line trials by the OCTIPS consortium. By translating the clinical observation of treatment failures into innovative cancer models that mimic relapsed ovarian cancer, we will validate improved front-line therapeutic strategies to help prolong patient survival. The impact of this application is that it defines a highly rigorous approach to integrate the bedside to bench to bedside paradigm, leading to novel prognosis-changing strategies for the treatment of ovarian cancer patients.

Data on routine systemic treatment of patients with ovarian cancer are currently available only to a limited degree. The alkylating agent treosulfan is approved in oral (p.o.) and intravenous (i.v.) form for the treatment of ovarian carcinoma. The present non-interventional study analyzed the clinical use of treosulfan in Germany, evaluating the mode of application, toxicity, and response and survival rate.Two hundred and forty-eight ovarian cancer patients in 57 Centers, who received treosulfan mainly either i.v. (5,000-8,000 mg/m(2) d1, q21d or q28d) or p.o. (400-600 mg/m(2) d1-14 or 21, q28d) for at least one therapy cycle were evaluable and were included in the study.With a median age of 70 years (range=36-92 years), predominantly elderly patients received treosulfan treatment. Most participants presented serous histology (131, 52.8%) and advanced-stage FIGO III (122, 49%) or IV (55, 22%) disease. Median ECOG status was 1 (range=0-2), whereas cardiac co-morbidity was common (31%). Treosulfan was usually administered as second- (26%), third- (21%) or fourth-line (17%) therapy. Two hundred and one patients received i.v. and 47 p.o.The most common reason for dose modifications was due to hematological toxicity (46%). The main reason for a therapy discontinuation was progressive disease (38.5%). Response was observed in 25.8% of participants, disease stabilization in 28.6 % and progress in 45.6%. The median progression-free and overall survival was 196 and 405 days, respectively.In predominantly elderly and heavily pre-treated patients with recurrent ovarian cancer, treosulfan featured a clinical relevant efficacy and well-manageable, mostly hematological, toxicity, which resulted in a positive therapeutic index.

The Patients Anastrozole Compliance to Therapy (PACT) program is a large randomized study designed to assess whether the provision of educational materials (EM) could improve compliance with aromatase inhibitor therapy in postmenopausal women with early, hormone receptor-positive breast cancer.The PACT study presented a large, homogeneous dataset. The baseline analysis included patient demographics and initial treatments and patient perceptions about treatment and quality of life.Overall, 4,923 patients were enrolled at 109 German breast cancer centers/clinics in cooperation with 1,361 office-based gynecologists/oncologists. 4,844 women were randomized 1:1 to standard therapy (n = 2,402) or standard therapy plus EM (n = 2,442). Prior breast-conserving surgery and mastectomy had been received by 76% and 24% of the patients, respectively. Radiotherapy was scheduled for 85% of the patients, adjuvant chemotherapy for 38%. Reflecting the postmenopausal, hormone-sensitive nature of this population, only 285 patients (7%) had received neoadjuvant chemotherapy.A comparison with epidemiological data from the West German Breast Center suggests that the patients in the PACT study are representative of a general postmenopausal early breast cancer population and that the findings may be applicable to real-world Germany and beyond. Compliance data from PACT are eagerly anticipated.
