NET-02 trial protocol: a multicentre, randomised, parallel group, open-label, phase II, single-stage selection trial of liposomal irinotecan (nal-IRI) and 5-fluorouracil (5-FU)/folinic acid or docetaxel as second-line therapy in patients with progressive poorly differentiated extrapulmonary neuroendocrine carcinoma (NEC).

INTRODUCTION: Poorly differentiated (PD), extrapulmonary (EP), neuroendocrine carcinomas (NECs) are rare but aggressive neuroendocrine neoplasms. First-line treatment for advanced disease is an etoposide and platinum-based chemotherapy combination. There is no established second-line treatment for patients with PD-EP-NEC, and this is an area of unmet need. METHODS AND ANALYSIS: NET-02 is a UK, multicentre, randomised (1:1), parallel group, open-label, phase II, single-stage selection trial of liposomal irinotecan (nal-IRI)/5-fluorouracil (5-FU)/folinic acid or docetaxel as second-line therapy in patients with progressive PD-EP-NEC. One hundred and two eligible participants will be randomised to receive either nal-IRI/5-FU/folinic acid or docetaxel. The primary objective is to determine the 6-month progression-free survival (PFS) rate. The secondary objectives of this study are to determine PFS, overall survival, objective response rate, toxicity, quality of life and whether neuron-specific enolase is predictive of treatment response. If either treatment is found to have a 6-month PFS rate of at least 25%, that treatment will be considered for a phase III trial. If both treatments meet this target, prespecified selection criteria will be applied to establish which treatment to take forward. ETHICS AND DISSEMINATION: This study has ethical approval from the Greater Manchester Central Research Ethics Committee (reference no. 18/NW/0031) and clinical trial authorisation from the Medicine and Healthcare Products Regulatory Agency. Results will be published in peer-reviewed journals and uploaded to the European Union Clinical Trials Register. TRIAL REGISTRATION NUMBERS: ISRCTN10996604, NCT03837977, EudraCT Number: 2017-002453-11.

Outcomes in patients ≥ 80 years with a diagnosis of a hepatopancreaticobiliary (HPB) malignancy.

Older patients are underrepresented in oncological clinical trials. The incidence of hepatopancreaticobiliary (HPB) malignancies is higher in older patients, but data on outcomes are lacking. This study assessed patient outcomes in those < 80 and ≥ 80 years with a HPB malignancy seen at a tertiary referral centre, The Christie NHS Foundation Trust. Data on patients with a HPB malignancy were collected retrospectively between 2012 and 2017 via on-line case-note review. Survival was calculated using the Kaplan-Meier method and prognostic factors using log-rank analysis. Of 1421 patients, 10% were ≥ 80 years. Of patients < 80 and ≥ 80 years, 56% and 57% had pancreas cancer, 39% and 36% biliary tract cancer, and 5% and 7% had hepatocellular carcinoma, respectively. Amongst patients ≥ 80 years, 75% had an Eastern Cooperative Oncology Group performance status (ECOG PS) 0-2. Patients ≥ 80 years had higher rates of comorbidity; 28% received systemic anti-cancer therapy (SACT), compared with 62% of patients < 80 years. Best supportive care (BSC) was instituted in 44% of older patients, compared with 13% in those < 80 years. Of patients ≥ 80 years who received SACT, 82% received monotherapy. Median overall survival (OS) for patients receiving palliative SACT was 10.07 months (95% CI 8.89-11.08) and 10.10 months (95% CI 6.30-12.30) in patients < 80 and ≥ 80 years, respectively, p 0.41; ECOG PS (p < 0.001) was prognostic for OS in older patients but Adult Comorbidity Evaluation-27 comorbidity score (p = 0.07, when comparing groups of ACE score ≤ 1 and > 1) was not. Baseline factors were similar in both age cohorts, but more comorbidities were present in older patients. Older patients were less likely to receive SACT, but when they did, they had an equivalent benefit in OS to younger patients.

[Imaging before and after endoscopic lung volume reduction]. / Bildgebung vor und nach endoskopischer Lungenvolumenreduktion.

The treatment of symptomatic lung emphysema by lung volume reduction has become established over the last 15 years. While surgical partial lung resection has profited from improved and less invasive surgical techniques, various endoscopic interventional procedures have been developed and are now available for use. All treatment approaches are dependent on individual anatomical variants and a regional distribution of the lung emphysema, which is why no procedure can be designated as the gold standard for all patients. High-resolution computed tomography can be qualitatively evaluated and provides decisive information for treatment, which is why radiologists play a particularly important role in treatment planning and aftercare of an intervention for reduction of the lung volume. This article presents the various endoscopic techniques, names the demands of the treating physician on the advising radiologist and finally describes how a treatment decision is derived from the results obtained.

Urgent need for consensus: international survey of clinical practice exploring use of platinum-etoposide chemotherapy for advanced extra-pulmonary high grade neuroendocrine carcinoma (EP-G3-NEC).

BACKGROUND: Platinum-etoposide (PE) chemotherapy (CH) is a globally established combination for extra-pulmonary high grade neuroendocrine carcinoma (EP-G3-NEC); the optimal schedule has not been established. METHODS: An international survey was designed, and completed by clinicians with an expertise in the field to assess consistency in clinical practice. RESULTS: Seventy-five replies were received (June-Nov'17). A minority of physicians (13; 17.6%) did not take Ki-67 or morphology (9; 12.0%) into consideration for selection of CH. Most (72; 96.0%) selected PE-CH as first-line treatment for EP-G3-NEC. CH schedules varied: cisplatin-based (37/71; 52.1%), carboplatin-based (34/71; 47.9%); intravenous etoposide (64/71; 90.1%), oral etoposide (7/71; 9.9%). Choice of second-line CH depended on time to progression on PE-based first-line: if > 6 months, re-challenge with PE was the preferred choice (34; 45.9%); if < 6 months, alternative combinations such as fluoropyrimidine/irinotecan (21; 29.2%) or temozolomide/capecitabine (22; 30.6%) were used. CONCLUSION: Significant variation in PE regimen employed exists. Standardising clinical practice would facilitate clinical trial development.

Phase III randomized study of second line ADI-PEG 20 plus best supportive care versus placebo plus best supportive care in patients with advanced hepatocellular carcinoma.

Background: Arginine depletion is a putative target in hepatocellular carcinoma (HCC). HCC often lacks argininosuccinate synthetase, a citrulline to arginine-repleting enzyme. ADI-PEG 20 is a cloned arginine degrading enzyme-arginine deiminase-conjugated with polyethylene glycol. The goal of this study was to evaluate this agent as a potential novel therapeutic for HCC after first line systemic therapy. Methods and patients: Patients with histologically proven advanced HCC and Child-Pugh up to B7 with prior systemic therapy, were randomized 2 : 1 to ADI-PEG 20 18 mg/m2 versus placebo intramuscular injection weekly. The primary end point was overall survival (OS), with 93% power to detect a 4-5.6 months increase in median OS (one-sided α = 0.025). Secondary end points included progression-free survival, safety, and arginine correlatives. Results: A total of 635 patients were enrolled: median age 61, 82% male, 60% Asian, 52% hepatitis B, 26% hepatitis C, 76% stage IV, 91% Child-Pugh A, 70% progressed on sorafenib and 16% were intolerant. Median OS was 7.8 months for ADI-PEG 20 versus 7.4 for placebo (P = 0.88, HR = 1.02) and median progression-free survival 2.6 months versus 2.6 (P = 0.07, HR = 1.17). Grade 3 fatigue and decreased appetite occurred in <5% of patients. Two patients on ADI-PEG 20 had ≥grade 3 anaphylactic reaction. Death rate within 30 days of end of treatment was 15.2% on ADI-PEG 20 versus 10.4% on placebo, none related to therapy. Post hoc analyses of arginine assessment at 4, 8, 12 and 16 weeks, demonstrated a trend of improved OS for those with more prolonged arginine depletion. Conclusion: ADI-PEG 20 monotherapy did not demonstrate an OS benefit in second line setting for HCC. It was well tolerated. Strategies to enhance prolonged arginine depletion and synergize the effect of ADI-PEG 20 are underway. Clinical Trial number: www.clinicaltrials.gov (NCT 01287585).

Identification of clinical biomarkers for patients with advanced hepatocellular carcinoma receiving sorafenib.

BACKGROUND: Identification of patients with advanced HCC-deriving preferential benefit from sorafenib is desirable, and treatment-related adverse events are potential clinical biomarkers. METHODS: Survival and toxicity data for patients with HCC treated with sorafenib at the Christie NHS Foundation Trust from 11/09 to 02/15 were collected retrospectively. RESULTS: Eighty-five eligible patients were identified. The most common grade 3 or 4 treatment-related toxicities were hypertension (HTN, 45 %), fatigue (8 %), and hand-foot syndrome (HFS, 8 %). Any-grade HFS and/or worsening HTN (HFS/HTN) were experienced by 58 % of patients. Estimated median progression-free and overall survival (OS) were 4.6 (95 % CI 2.8-5.2) and 6.5 (95 % CI 4.9-8.01) months, respectively. Child-Pugh score (p value <0.001) and the development of HFS/HTN were independent prognostic factors impacting on OS on multivariable analysis. Patients who developed HFS/HTN had median OS of 8.2 months (95 % CI 6.5-12.4) compared with 4.1 (95 % CI 2.7-5.4) for those without this toxicity (Hazard Ratio (HR) 0.4, 95 % CI 0.2-0.7, p value 0.003). The prognostic impact of HFS/HTN was confirmed by landmark analyses limited to patients who lived a minimum of 2 months (p value 0.019) or who developed HFS/HTN in the first 3 months of treatment (p value 0.006). CONCLUSION(S): The development of toxicities specific to sorafenib is associated with prolonged survival in a UK-based HCC patient series; prospective assessment of their significance is required.

Sorafenib for the Treatment of Advanced Hepatocellular Cancer - a UK Audit.

AIMS: Sorafenib is the current standard treatment for advanced hepatocellular carcinoma. We carried out a national audit of UK patients treated with sorafenib as standard-of-care and those treated with systemic therapy in first-line trials. MATERIALS AND METHODS: Sorafenib-treated and trial-treated patients were identified via the Cancer Drugs Fund and local databases. Data were collected retrospectively from medical records according to a standard case report form. The primary outcome measure was overall survival, estimated by the Kaplan-Meier method. RESULTS: Data were obtained for 448 sorafenib-treated patients from 15 hospitals. The median age was 68 years (range 17-89) and 75% had performance status ≤ 1. At baseline, 77% were Child-Pugh A and 16.1% Child-Pugh B; 38% were albumin-bilirubin grade 1 (ALBI-1) and 48% ALBI-2; 23% were Barcelona Clinic Liver Classification B (BCLC-B) and 72% BCLC-C. The median time on sorafenib was 3.6 months, with a mean daily dose of 590 mg. The median overall survival for 448 evaluable sorafenib-treated patients was 8.5 months. There were significant differences in overall survival comparing Child-Pugh A versus Child-Pugh B (9.5 versus 4.6 months), ALBI-1 versus ALBI-2 (12.9 versus 5.9 months) and BCLC-B versus BCLC-C (13.0 versus 8.3 months). For trial-treated patients (n=109), the median overall survival was 8.1 months and this was not significantly different from the sorafenib-treated patients. CONCLUSION: For Child-Pugh A patients with good performance status, survival outcomes were similar to those reported in global randomised controlled trials. Patients with ALBI grade > 1, Child-Pugh B or poor performance status seem to derive limited benefit from sorafenib treatment.

Prognostic factors for disease relapse in patients with neuroendocrine tumours who underwent curative surgery.

AIM: Surgery is the only modality of cure in patients diagnosed with neuroendocrine tumours (NETs). The aim of this study was to identify prognostic factors associated with disease relapse in patients with NETs treated by potentially-curative surgery. METHODS: Sequential patients registered in The Christie European NET Society (ENETS) Centre of Excellence, with grade (G)1 or G2 NETs who had undergone curative surgery (February 2002-June 2014) were included. Investigated prognostic factors for relapse were: age, gender, TNM stage, tumour-localisation, functionality, genetic predisposition, presence of multiple NETs, second malignancy, grade (Ki-67-based), presence of vascular and/or perineural invasion, necrosis, surgical margin (R0/R1), Eastern Cooperative Oncology Group performance status and Adult Comorbidity Evaluation co-morbidity score. RESULTS: One hundred and eighty-eight patients were identified [median age of 60 years (range 16-89)]. With a median follow-up of 2.6 years, 43 relapses occurred. The estimated median relapse-free survival (RFS) for the entire cohort was 8.0 years (95% confidence interval [CI] 5.9-10.0 years). In univariate analysis, primary NET location (p = 0.01), ENETS T-(HR-1.4; 95%-CI 1.0-2.0, p = 0.026), N-(HR-2.0, 95%-CI 1.1-3.9, p = 0.026) and M-stage (HR-2.6, 95%-CI 1.1-6.3, p = 0.052), grade (Ki-67%-based) (HR-2.5; 95%-CI 1.4-4.7; p = 0.003) and perineural invasion (HR-2.1; 95%-CI 1.1-3.9; p = 0.029) were prognostic for relapse. Factors remaining significant after multivariable analysis were tumour size (HR-1.67; 95%-CI 1.04-2.70; p = 0.03), nodal involvement (HR-2.61; 95%-CI 1.17-5.83; p = 0.013) and Ki-67 at the time of diagnosis (HR-1.93; 95%-CI 1.24-3.0; p = 0.002). CONCLUSION: Size of tumour, lymph node involvement and Ki-67 were independent prognostic factors for relapse after potentially curative surgery in NET.

Routine measurement of plasma chromogranin B has limited clinical utility in the management of patients with neuroendocrine tumours.

OBJECTIVE: Chromogranin A (CgA) and B (CgB) are markers for monitoring disease status in patients with gastroenteropancreatic neuroendocrine tumours (NETs). These are specialized diagnostic tests often necessitating referral of specimens to a supraregional assay service (SAS) laboratory for analysis. The aim of this audit was to assess whether measurement of either plasma CgA or CgB alone provides sufficient clinical information in comparison with the current practice of measuring both markers together. DESIGN: A retrospective analysis was undertaken for all chromogranin tests requested for patients with a known NET diagnosis. Results were categorized based on whether plasma concentrations were elevated for one or both CgA and CgB. RESULTS: A total of 325 sequential patients with a NET diagnosis had plasma chromogranin levels measured during the period of review. Baseline CgA was elevated in 60·9% of patients. Isolated elevations in CgA (with normal CgB) were found in 44·9% of patients, whilst combined elevations in both CgA and CgB were found in 16% of patients. Combined CgA and CgB concentrations within the normal range were observed for 38·5% of patients. Only two patients (0·6%) had an isolated elevation in CgB at baseline. Both patients had a diagnosis of pancreatic NET and were radiologically stable. Plasma CgA and CgB corresponded with disease stage (localized vs metastatic). CgB in addition to CgA did not provide any significant improvement in diagnostic performance for identification of metastatic disease compared to CgA alone. CONCLUSIONS: Based on this NET population and specific assay performance characteristics, CgA alone provides sufficient information for the management of NET patients; the routine estimation of CgB in all patients is not informative in clinical practice.

Second-line chemotherapy in advanced biliary cancer: a systematic review.

The randomized NCRN phase III ABC-02 trial provided level-A evidence for first-line chemotherapy with cisplatin and gemcitabine combination in advanced biliary cancer (ABC). This systematic literature review aims to evaluate the level of evidence for the use of second-line chemotherapy for patients with ABC in terms of overall survival (OS), response, toxicity and quality of life. Eligible studies were identified using Medline, ASCO, ESMO and the World Gastrointestinal Congress databases. Searches were last updated on 15 December 2013. Eligible studies reported survival and/or response data for patients with ABC receiving second-line systemic chemotherapy. This systematic review was registered in the PROSPERO database (No. CRD42013004205). Five hundred and fifty-eight studies were identified from the searches in Medline (n = 342), ASCO (n = 160), ESMO (n = 27) and World Gastrointestinal Congress (n = 29). Twenty-five studies were eligible: 14 phase II clinical trials, 9 retrospective analyses and 2 case reports. In total, data from 761 patients were reported with median number of patients included in each study of 22 (range 9-96). The mean OS was 7.2 months [95% confidence interval (CI) 6.2-8.2] [phase II: 6.6 (95% CI 5.1-8.1); retrospective analysis: 7.7 (95% CI 6.5-8.9)]. The mean progression-free survival (PFS), response rate (RR) and disease control rate were 3.2 months (95% CI 2.7-3.7), 7.7% (95% CI 4.6-10.9) and 49.5% (95% CI 41.4-57.7), respectively. The best correlations were between OS and PFS for all studies (r = 0.54; P = 0.01) and between OS and PFS (r = 0.61; P = 0.04) and OS and RR (r = 0.62; P = 0.03) for phase II studies, respectively. Biliary tract cancer is known to be a chemo-responsive disease. There is insufficient evidence (level C) to recommend a second-line chemotherapy schedule in ABC, although the available data suggest that a cohort of patients may benefit. Further prospective and randomized studies are needed to clarify the relative value of second-line chemotherapy in this setting.

Influence of co-morbidity on renal function assessment by Cockcroft-Gault calculation in lung cancer and mesothelioma patients receiving platinum-based chemotherapy.

BACKGROUND: Creatinine clearance (CrCl) estimation by Cockcroft-Gault calculation (CG) often replaces measurement of glomerular filtration rate (GFR) by [(51)Cr]-ethylenediaminetetraacetic acid clearance (EDTA). Co-morbidity, age, and renal impairment influence the accuracy of CG, whilst the relationship between CG and EDTA has been poorly assessed in lung cancer patients, a population significantly affected by these covariates. METHODS: Retrospective analysis of co-morbidity, nephrotoxic drug use, chemotherapy toxicity, and correlation between paired CG and EDTA, in 388 lung cancer and mesothelioma patients receiving platinum-based chemotherapy. RESULTS: Potentially nephrotoxic co-morbidity or medication use occurred in 47% of patients, and was twice as likely in those aged >70 years (OR=2.07; 95%CI: 1.25-3.44, p=0.003). Patients with co-morbidity or nephrotoxic medication use had a lower EDTA compared to those without these baseline factors (p=0.02), but were not significantly more likely to experience chemotherapy toxicity. CG and EDTA correlation was high (r(2)=0.68), but reduced in patients with ETDA<50 ml/min (r(2)=0.26, p=0.02) or >120 ml/min (r(2)=0.32, p=0.09), and in those with CG>120 ml/min (r(2)=0.20, p=0.01). The correlation between CG and EDTA was not significantly altered in patients with co-morbidity or nephrotoxic medication use. CG bias (mean percentage error) and precision (mean absolute percentage error, MAPE) were 7% and 26%, respectively, and precision was impaired in patients with abnormally raised serum creatinine (MAPE 65%, p<0.0001). CONCLUSION: CG estimation of CrCl is accurate and safe in lung cancer patients with potentially nephrotoxic co-morbidity or concomitant medication, but should not be used when values are outside the range 50-120 ml/min, or with abnormally elevated serum creatinine.

Histology classification is not a predictor of clinical outcomes in advanced non-small cell lung cancer (NSCLC) treated with vinorelbine or gemcitabine combinations.

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.

Folate and colorectal cancer prevention.

Anti-folate chemotherapy agents such as methotrexate and fluorouracil reduce proliferation of neoplastic cells by inhibiting DNA synthesis. Paradoxically epidemiological data suggests an inverse relationship between dietary folate intake and incidence of colorectal cancer (CRC). On the basis of this and other putative health benefits around 35% of the North American population take folic acid supplements, in addition to natural food folates and fortified flour and cereal grains. Recently, randomised controlled trials investigating folic acid as a secondary preventative agent in colorectal neoplasia have shed further light on the relationship between folate and colorectal carcinogenesis, corroborating data from animal models indicating opposing effects dependent on the timing of exposure in relation to the development of neoplastic foci. A 'dual-modulator' role for folate in colorectal carcinogenesis has been proposed in which moderate dietary increases initiated before the establishment of neoplastic foci have a protective influence, whereas excessive intake or increased intake once early lesions are established increases tumorigenesis. Functional polymorphic variants in genes encoding key enzymes in the folate metabolic pathway add a further layer of complexity to the relationship between folate and CRC risk. Here, we review the evidence concerning the efficacy and safety of folate as a potential CRC chemopreventive agent.

Guidelines for the transfusion of red cells.

The following recommendations, which aim at standardising and rationalising clinical indications for the transfusion of red cells in Belgium, were drawn up by a working group of the Superior Health Council. To this end, the Superior Health Council organised an expert meeting devoted to "Guidelines for the transfusion of red cells" in collaboration with the Belgian Hematological Society. The experts discussed the indications for red cell transfusions, the ideal red cell concentrate, the practical issues of administering red cells, and red cell transfusions in patients in a critical condition. The recommendations formulated by the experts were validated by the working group with the purpose of harmonising red cell transfusion in Belgian hospitals.

Thymidylate synthase polymorphisms, folate and B-vitamin intake, and risk of colorectal adenoma.

The effects of polymorphisms in genes coding for key folate metabolism enzymes such as thymidylate synthetase (TS) on colorectal neoplasia risk are likely to be influenced by gene-gene and gene-nutrient interactions. We investigated the combined effects of three polymorphisms in the TS gene region, TSER, TS 3R G>C, and TS 1494del6, dietary intakes of folate and other B vitamins, and genotype for other folate metabolism variants, in a colorectal adenoma (CRA) case-control study. Individuals homozygous for TS 1494del6 del/del were at significantly reduced CRA risk compared to those with either ins/del or ins/ins genotypes (odds ratio 0.52; 95% confidence interval: 0.31-0.85, P=0.009). We also observed evidence of interactions between TS 1494del6 genotype and intake of folate, and vitamins B6 and B12, and MTHFR C677T genotype, with the reduction in risk in del/del homozygotes being largely confined to individuals with high nutrient intakes and MTHFR 677CC genotype (P interaction=0.01, 0.006, 0.03, and 0.07, respectively). TSER genotype, when considered either alone or in combination with TS 3R G>C genotype, did not significantly influence CRA risk. These findings support a role for TS in colorectal carcinogenesis, and provide further evidence that functional polymorphisms in folate metabolism genes act as low-risk alleles for colorectal neoplasia and participate in complex gene-gene and gene-nutrient interactions.

Combination chemotherapy with carboplatin, capecitabine and epirubicin (ECarboX) as second- or third-line treatment in patients with relapsed ovarian cancer: a phase I/II trial.

Platinum-based combination chemotherapy has been proven to be superior to single-agent platinum in the treatment of relapsed ovarian cancer after a treatment-free interval of more than 6 months. A response rate of 41% was previously reported by our group using a combination of epirubicin, cisplatin and 5-FU in patients who relapsed within 12 months, we therefore assessed a similar, but more convenient combination of epirubicin, carboplatin and capecitabine in this phase-I/II trial. In total, 18 patients with recurrent epithelial ovarian carcinoma, who had not received more than two lines of chemotherapy and the treatment-free interval exceeded 6 months were treated with carboplatin AUC5, epirubicin 50 mg m(-2) and capecitabine at several dose levels on continuous 21 day cycles and 14 of 21 day cycles. Patients were assessed for toxicity and by CT and CA-125 for response. The overall response rate was 61.1%, with three complete and eight partial responses. Grade 3/4 haematological toxicity was seen in 10 out of 18 patients and caused dose reductions and treatment delays. The combination of epirubicin, carboplatin and capecitabine showed good activity but caused excessive toxicity. A phase-II trial using carboplatin and capecitabine is underway.

Bisphosphonates' use in metastatic bone disease.

Bisphosphonates already have an established role in the management of the skeletal complications of metastatic bone disease. The development of new, highly potent compounds has led to investigation into their use as preventive agents in the adjuvant setting. The aim of the paper is to evaluate the evidence for their use in prevention and treatment.

Fast T1- and T2-weighted pulmonary MR-imaging in patients with bronchial carcinoma.

PURPOSE: A prospective study to evaluate the diagnostic potential and limitations of three fast MRI sequences in patients with bronchial carcinoma based on the comparison with spiral CT. MATERIAL AND METHODS: Three fast chest MRI sequences from 20 patients with central or peripheral bronchial carcinoma were evaluated by two observers for relation of tumour to adjacent structures, lymph node enlargement, additional pulmonary lesions and artefacts. The information from MR-imaging was compared with the results from spiral CT. MRI comprised a T1-3D-GRE breath-hold examination ("VIBE", TR/TE 4.5/1.9 ms, flip-angle 12 degrees , matrix 502 x 512, 2.5 mm coronal slices), a breath-hold, T2-HASTE sequence (TR/TE 2000/43 ms, matrix 192 x 256, 10 mm coronal slices) and a respiration-triggered T2-TSE sequence (TR/TE 3000-6000/120 ms, matrix 270 x 512, 6 mm transverse slices). The FOV was adapted individually (380-480 mm). RESULTS: The presence of the primary bronchial carcinoma and infiltration of thoracic structures by tumour tissue could be demonstrated by all sequences. VIBE sequence was more suitable for detecting small pulmonary nodules than the other MRI examinations, but compared to CT still 20% of these lesions were missed. Contrary to VIBE and T2-weighted TSE scans, HASTE sequence was limited in imaging mediastinal lymph nodes due to missing relevant findings in 2/20 patients. HASTE images significantly provided the lowest rate of artefacts in imaging lung parenchyma (P < 0.001 in peripheral parenchyma), but spatial resolution was limited in this sequence. Concerning the differentiation between tumour and adjacent atelectasis (n = 8), T2-weighted TSE imaging was superior to CT and VIBE in all cases and to HASTE sequence in 4/8 patients. CONCLUSION: The combination of VIBE and HASTE sequence allows for an adaequate imaging of thoracic processes in patients with bronchial carcinoma, limited only in visualizing small pulmonary nodules. To obtain more detail resolution and to differentiate tumour tissue from adjacent atelectasis, T2-TSE examination may be added in selected cases.
