Abstract
INTRODUCTION Systemic chemotherapy improves survival in oesophagogastric cancer however no standard second-line regimen exists due to a paucity of randomised data. Docetaxel combined with irinotecan (DI) provides a suitable option due to the lack of cross-reactivity with first-line therapeutics and a tolerable toxicity profile. METHODS We retrospectively reviewed a cohort of patients with advanced oesophagogastric cancer in two institutions treated with the combination of docetaxel 35 mg/m(2) plus irinotecan 60 mg/m(2) day 1 and day 8 every 21 days, following progression with first-line platinum-based therapy. RESULTS Between January 2000 and September 2009, 41 eligible patients were identified. Median age was 58 years, male:female 25:16, adenocarcinoma:squamous cell carcinoma 37:4, oesophageal:oesophagogastric junction:gastric 7:10:24. Locally advanced:metastatic disease 6:35. Previous radical surgery:radiotherapy:both 6:4:7. 27/41 had progressed within 90 days of receiving platinum-based therapy. Median number of chemotherapy cycles: 3 (range 1-12). Eight patients required dose reductions due to DI toxicity. 10/28 evaluable patients had a response, median progression-free survival (PFS) was 11 weeks (95% confidence intervals (CI): 9-13 weeks) with median overall survival 24 weeks (95%CI: 12-35 weeks). No significant prognostic factors were identified. CONCLUSION Weekly docetaxel combined with irinotecan has acceptable safety and modest efficacy in the second-line treatment of advanced oesophagogastric cancer. Further prospective evaluation of this regimen is warranted.

Abstract
Angiogenesis plays a key role in glioblastoma biology and antiangiogenic agents are under clinical investigation with promising results. However, the angiogenic profiles of patients with glioblastoma and their clinical significance are not well understood. Here we characterize the serum angiogenic profile of patients with glioblastoma, and examine the prognostic significance of individual angiogenic factors. Serum samples from 36 patients with glioblastoma were collected on admission and simultaneously assayed for 48 angiogenic factors using protein microarrays. The data were analyzed using hierarchical cluster analysis. Vessel morphology was assessed histologically after immunostaining for the pan-endothelial marker CD31. Tumor samples were also immunostained for tissue inhibitor of metalloproteinase-1 (TIMP-1). Cluster analysis of the serum angiogenic profiles revealed 2 distinct subtypes of glioblastoma. The 2 subtypes had markedly different tumor microvessel densities. A low serum level of TIMP-1 was associated with significantly longer survival independent of patient age, performance status, or treatment. The serum angiogenic profile in patients with glioblastoma mirrors tumor biology and has prognostic value. Our data suggest the serum TIMP-1 level as an independent predictor of survival.

Abstract
Abstract
Background: Routine clinical practice and a growing body of evidence support the continuation of trastuzumab (T) in patients with HER-2 positive (+ve) advanced breast cancer progressing on previous T-based therapy. Despite this, recent UK clinical guidance advises against continuing T on evidence of disease progression (PD) in the absence of brain metastases. This retrospective study therefore evaluated the outcome of patients (pts) with HER-2+ve locally advanced (LA) or metastatic breast cancer (MBC) who continued T beyond PD, treated in our Unit. Patients and methods: HER-2+ve pts receiving T for LA or MBC were identified from our prospectively maintained database and pharmacy records. Those receiving T beyond PD after adjuvant or one line of T for advanced disease were assessed for response and outcome. From thetimepoint of T continuation beyond PD we calculated the overall disease control rate (response or stable disease), time to progression (TTP), and overall survival (OS).
Results: 114 pts with HER-2+ve LA or MBC treated with T beyond PD were identified. At the time of analysis 35 (31%) pts were still alive with a median follow up of 20 months (mo). The main site of disease was visceral in 84 (74%) pts, including 37 (32%) pts with CNS involvement. 30 (26%) pts had soft tissue or bone metastases only. Fifty nine (52%) pts had received adjuvant chemotherapy and 13 (11%) pts had received adjuvant T. Seventy six (66%) pts had 1 line of chemotherapy prior to continuation of T beyond PD and 21 (19%) had 2 or more lines. Fifty three (46%) pts had previously received taxanes + T for their LA or MBC. Post-progression, 66 (58%) pts received T combined with chemotherapy; 12 (11%) taxane-based, 32 (28%) capecitabine and 22 (19%) vinorelbine. Information regarding response was not available in 21(18%) pts. Of the ninety three (82%) pts with documented clinical (n=16) or radiological (n=77) response evaluation, 68 (60%) pts were considered as having stable disease (SD) or better and 25 (22%) as having PD. The median duration of T was 10 mo (95% CI: 8-11 mo), the median TTP was 24wks (95% CI: 21-28 wks) and the median OS was 19 mo (95% CI:12-24mo). In a sub-group analysis of the 81(71%) pts who received T as first-line Rx or relapsed within 12 wks of adjuvant T, overall disease control was achieved in 50 (61%) pts, the median TTP was 25wks (95% CI:18-33 wks) and the median OS was 22 mo(95% CI:17-27mo). In terms of safety, only 6 (5%) pts overall had to discontinue T secondary to decline in left ventricular ejection fraction.
Conclusion: Our results from an unselected group of patients are supported by positive results from other studies and provide additional evidence that continuation of trastuzumab beyond disease progression is of clinical benefit.

Abstract
INTRODUCTION More than a third of children with ependymoma experience relapse, and despite multimodal treatment, less than 25% of them can then achieve long-term survival. Prognostic factors for patients who relapse have not been extensively analyzed. PATIENTS AND METHODS We retrospectively analyzed 82 patients from four pediatric oncology European institutions in order to identify prognostic factors and influence of treatment modalities in relapsed ependymoma. RESULTS First relapse occurred after a median of 19 months (1 month-16 years). Five-year progression-free survival and overall survival of the cohort were 17% and 27.6%, respectively. Survival was statistically significantly higher for patients achieving gross total resection. No survival benefit was seen for children receiving chemotherapy whereas patients who were amenable to some form of re-irradiation had a better outcome. Objective responses were found in more than 25% of patients receiving oral etoposide, temozolomide, or vincristine/etoposide/cyclophosphamide regimens. Multivariate analysis confirmed that patients with mixed relapses, no surgery at relapse, and receiving chemotherapy did worse (hazard ratio = 3.6, 3.3, and 1.7, respectively, all p < 0.05). DISCUSSION Relapsed ependymoma carries a very poor prognosis with an indolent chronic course, leading to death in approximately 90% of the patients. Complete surgical resection whenever possible should be encouraged. Radiation therapy of the relapsed lesions can provide some minor benefit whereas chemotherapy despite the occasional responses provides no benefit in the final outcome which is dismal. Efforts have to be orchestrated internationally to enroll these patients on clinical trials using biology-based therapies.

Abstract
Single agent capecitabine is effective and well tolerated in metastatic breast cancer (MBC). We have retrospectively analysed capecitabine outcome as 1st, 2nd or 3rd line chemotherapy in 89 elderly patients ≥70 years with locally advanced or MBC treated in our Unit, 55 (62%) as 1st line and 34 (38%) as 2nd or 3rd line. Starting dose was 1000 mg/m(2) twice daily, days 1-14 every 3 weeks, but 36 (41%) started on a 25% dose reduction because of frailty and 12 (13%) reduced dose after the 1st or the 2nd cycle. Overall response rate (ORR) was 45% (95% CI: 35-55%). A further 19 (21%) achieved stable disease (SD) for ≥6 months. Median time to progression (TTP) and overall survival (OS) were 30 (95% CI: 23-37) and 61 (95% CI: 44-77) weeks, respectively. The ORR for 1st line treatment was 51% compared with 35% for 2nd and 3rd line treatment (p = 0.03). No significant difference in efficacy was seen between patients receiving the full versus reduced dose. Capecitabine was well tolerated, although 35% had treatment delays and 57% required dose reduction. Grade 3-4 toxicities were hand-foot syndrome in 11%, lethargy 9% and diarrhoea 2%. Capecitabine is an effective and well-tolerated drug in elderly patients with MBC including for 1st line treatment. Dose reduction is frequently required but does not appear to affect outcome.

Abstract
BACKGROUND The global lapatinib expanded access programme provided access to lapatinib combined with capecitabine for women with HER2-positive metastatic breast cancer (MBC) who previously received anthracycline, taxane and trastuzumab. METHODS Progression-free survival (PFS) and safety data for 356 patients recruited from the United Kingdom are reported. Efficacy was assessed in 162 patients from the five lead centres, including objective tumour response rate (ORR), time to disease progression (TTP) and efficacy in those with central nervous system (CNS) metastases. Correlation of PFS and ORR with previous capecitabine treatment was also documented. RESULTS Overall, PFS for the 356 UK patients was 21 weeks (95% CI: 17.6-24.7). In the 162 assessable patients, ORR was 21% (95% CI: 15-27%) and median TTP was 22 weeks (95% CI: 17-27). Efficacy was greater in capecitabine-naive patients (ORR 23 vs 16.3%, P=0.008). For 34 patients with CNS metastases, ORR was 21% (95% CI: 9-39%), with evidence of improvement in neurological symptoms, and median TTP was 22 weeks (95% CI: 15-28). CONCLUSIONS Lapatinib combined with capecitabine is an active treatment option for women with refractory HER2-positive MBC, including those with progressive CNS disease.

Abstract
BACKGROUND Until recently, histology has not been clearly or consistently described in the literature as a prognostic or predictive variable in advanced NSCLC studies. We have categorised patients treated with vinorelbine and gemcitabine based first line chemotherapy regimes for advanced NSCLC as either squamous or non-squamous, and also as either adenocarcinoma and non-adenocarcinoma, and compared outcome. MATERIAL AND METHODS 420 patients treated with platinum/gemcitabine, platinum/vinorelbine or single agent gemcitabine or vinorelbine as first line chemotherapy for advanced NSCLC were identified. The influence of pathology on progression free survival (PFS) and overall survival (OS) has been investigated by means of a Cox regression analysis. Hazard ratios with 95% CIs have been given for each pathological type after adjusting for the effects of age, gender, stage (III vs. IV), PS (0/1 vs. 2/3) and treatment type (platinum doublet vs. single agent). RESULTS Neither univariate nor multivariate analysis suggested that there was a significant difference in the response rates for adenocarcinoma vs. non-adenocarcinoma or between squamous and non-squamous pathology. There was no difference in PFS between adenocarcinoma and non-adenocarcinoma pathologies until 8 months (p = 0.98), and there was a statistically significant advantage in PFS for squamous vs. non-squamous pathologies (p = 0.04). Using multivariate Cox regression analysis to adjust for the effects of age, gender, stage, PS, and treatment type, the pathology subtype was not significant. There was no difference in OS in any group. CONCLUSIONS These results suggest that histology may not be considered as a predictor of clinical outcome using these drugs.

Abstract
The role of radiofrequency ablation (RFA) in metastatic sarcoma is not well defined. The aim of this study was to evaluate the efficacy and safety of RFA in a series of sarcoma patients. A retrospective search of a prospectively maintained database identified 13 gastrointestinal stromal tumour (GIST) patients and 12 with other histological subtypes treated with RFA. All the GIST patients received RFA for metastatic disease in the liver: 12 of these responded to the first RFA procedure and one achieved stable disease. Two GIST patients received RFA on two occasions to separate lesions within the liver and both responded to the second RFA procedure. Of the other subtypes: 7 underwent RFA to liver lesions, 5 of these responded to RFA, one progressed and 1 was not assessable for response at the time of analysis. All 5 patients with lung metastases achieved a response following their first RFA procedure. RFA was effective and well tolerated in this series of sarcoma patients. RFA may have a role in patients with GIST who have progression in a single metastasis but stable disease elsewhere. Further larger studies are required to better define the role of this technique in this patient population.

Abstract
Background: 20-yrs after starting the randomized, double-blind RMTBCPT (13-year median follow-up) 186 women developed invasive breast cancer, 82 on tamoxifen and 104 on placebo1. There was a significant reduction in the incidence of invasive ER+ but not ER- breast cancer that was significant after but not during the 8yr treatment period. The phenotype of ER+ breast cancer is highly variable. We have therefore assessed PgR, HER2, EGFR and Ki67 expression in as many as possible of these tumours.Methods: Tumour blocks were available on 154 participants, 65 on tamoxifen and 89 on placebo a similar distribution to the whole population. Staining was conducted using the following antibodies: ER, clone 6F11(Vector); PgR, clone 16 (Vector); HER2, HercepTest + K5207 (Dako), FISH PathVysion (Abbott) for IHC 2+ cases; EGFR, clone 31G7 (Invitrogen); Ki67 clone Mib1(Dako). ER and PgR were quantified as H-scores, HER2 and EGFR as + or –, and Ki67 as % cells staining.Results: There were 47 and 18 ER+ and ER- tumours in the tamoxifen arm vs 76 and 13 in the placebo arm, showing a 37% (95% CI 10- 57%, p=0.01) reduction of ER+ tumours which was essentially the same as that in the whole population1.There were 38 and 27 PgR+ and PgR- tumours in the tamoxifen arm vs 58 and 31 in the placebo arm, showing a 33% (95% CI 0-56%, p=0.05) reduction of PgR+ tumours. The distribution of ER/PgR tumours according to arm and time on trial at tumour diagnosis is shown in the table (there were no ER-PgR+ cases).The decrement in ER+ tumours was predominantly in ER+PgR+ cases after 8yrs but extended to ER+PgR- cases. It is important to note that the post 8yr tumour phenotype cannot be affected by continued exposure to tamoxifen. ER levels were significantly lower in the tamoxifen-treated group even among tumours presenting as ER+ (median H-score 123 vs 161, p=0.02). There were 9 and 6 HER2+ and 11 and 12 EGFR+ cases in the tamoxifen and placebo arms, respectively (p=NS for both). The mean (95%CI) levels of Ki67 were 8.4% (6.3-11.1) and 8.5% (6.8-10.6) in the 2 arms, respectively.Discussion: The decrement in ER+ tumours in the tamoxifen-treated women was restricted to the post-treatment period and was similar to that seen in the overall population1. Among the ER+ group there was a similar proportional reduction of PgR+ and PgR- tumours by tamoxifen.There was no evidence of enhanced HER2 or EGFR expression or increased proliferation in tumours developing in the tamoxifen arm but ER expression was reduced even among ER+ tumours.1Powles et al, JNCI, 2007;99:283-90.

Abstract
INTRODUCTION One method to overcome the problem of lung tumour movement in patients treated with radiotherapy is to restrict tumour motion with an active breathing control (ABC) device. This study evaluated the feasibility of using ABC in patients receiving radical radiotherapy for non-small cell lung cancer. METHODS Eighteen patients, median (range) age of 66 (44-82) years, consented to the study. A training session was conducted to establish the patient's breath hold level and breath hold time. Three planning scans were acquired using the ABC device. Reproducibility of breath hold was assessed by comparing lung volumes measured from the planning scans and the volume recorded by ABC. Patients were treated with a 3-field coplanar beam arrangement and treatment time (patient on and off the bed) and number of breath holds recorded. The tolerability of the device was assessed by weekly questionnaire. Quality assurance was performed on the two ABC devices used. RESULTS 17/18 patients completed 32 fractions of radiotherapy using ABC. All patients tolerated a maximum breath hold time >15s. The mean (SD) patient training time was 13.8 (4.8)min and no patient found the ABC very uncomfortable. Six to thirteen breath holds of 10-14 s were required per session. The mean treatment time was 15.8 min (5.8 min). The breath hold volumes were reproducible during treatment and also between the two ABC devices. CONCLUSION The use of ABC in patients receiving radical radiotherapy for NSCLC is feasible. It was not possible to predict a patient's ability to hold breath. A minimum tolerated breath hold time of 15 s is recommended prior to commencing treatment.

Abstract
The aim of this study was to identify the effect of the installation of Premium View post-processing software on our mammographic reporting performance, in particular the effects on our recall rate, biopsy rate and cancer detection rate. The case notes and imaging of all patients discussed at the weekly indeterminate imaging multidisciplinary team meeting were reviewed retrospectively before, immediately after and at a delayed interval following the installation of Premium View post-processing software. Factors recorded included the mammographic abnormality, further investigations and final histology. The indeterminate mammogram rate increased significantly from a baseline of 5.7% (before Premium View) to 8.7% in the time period immediately after the installation of Premium View (p=0.002). The stereotactic biopsy rate also increased from 0.8% to 2.4% (p=0.001), with a significant increase in the overall cancer detection rate from 3.4% to 4.4% (p=0.02). In the follow-up period several months after the installation of Premium View, the indeterminate mammogram rate returned to a level similar to that before Premium View (6%; p=0.7). The stereotactic biopsy rate remained significantly higher at 1.6% (p=0.07), as did the overall cancer detection rate of 5.0% (p=0.003). In conclusion, the use of Premium View may lead to higher cancer detection rates, at the expense of an initial increase in recall rate. Although prospective studies are suggested, this result is of interest in light of the proposed installation of digital mammography across the NHS Breast Screening Programme.

Abstract
Accelerated (dose-dense) chemotherapy, in which the frequency of administration is increased without changing total dose or duration, may increase the efficacy of cancer chemotherapy. We performed a randomised Phase II study to assess the safety and relative toxicity of AC (doxorubicin; cyclophosphamide) vs E(epirubicin)C given by conventional or accelerated schedules as neoadjuvant or adjuvant chemotherapy for early breast cancer. Furthermore, the relative toxicity of doxorubicin and epirubicin remains uncertain. Patients were randomised to one of four arms; four courses of standard 3 weekly cyclophosphamide 600 mg m−2 in combination with doxorubicin 60 mg m−2 (AC) vs epirubicin 90 mg m−2 (EC) 3 weekly vs the same regimens administered every 2 weeks with pegfilgrastim (G-CSF). A total of 126 patients were treated, 42 with standard AC, 42 with accelerated AC, 19 with standard EC and 23 with accelerated EC. Significantly more grade 3/4 day one neutropenia was seen with standard (6/61, 10%) compared to accelerated (0/65,) regimens (P=0.01). A trend towards more neutropenic sepsis was seen in the combined standard and accelerated AC arms (12/84, 14%) compared to the combined EC arms (1/42, 2%), P=0.06. Falls in left ventricular ejection fraction were not increased with accelerated treatment. Accelerated AC and EC with pegfilgrastim are safe and feasible regimens in the treatment of early breast cancer with less neutropenia than conventional 3 weekly schedules.
