Trends in classification, referral and treatment and the effect on outcome of patients with glioma: a 20 year cohort.

This retrospective audit was conducted to examine the changes in patient characteristics, referral, treatment and outcome over a 20-year period in a large regional neuro-oncology centre, focusing on the impact of the changes in pathological classification of gliomas. Using the Edinburgh Cancer Centre (ECC) database all cases of glioma were identified and patient, tumour and treatment characteristics noted. Survival was calculated from date of surgery or, if no operation was performed, the date of referral. Comparison was made between four periods 1988-1992 (c1), 1993-1997(c2), 1998-2002(c3) and 2003-2007 (c4). During the 20 years, 1175 patients with a glioma were referred to ECC. The median age increased from 53 years to 57 years (p < 0.001) but the proportion without pathology remained unchanged (10%). The distribution of pathological grades changed over time Grade I-II: 24, 6, 6, and 6%, Grade III: 42, 27, 17, and 13% and Grade IV: 24, 61, 68, and 68% in c1, c2, c3 and c4, respectively (p < 0.001). Immediate RT was given to 68% (c1), 70% (c2), 78% (c3) and 79% (c4). Median interval from resection to RT reduced from 43 days (c1) to 36 days (c4) (p < 0.001). 5-year overall survival for patients with Grade III lesions increased: 21% (c1), 35% (c2), 37% (c3), 33% (c4) as did 1-year overall survival for Grade IV lesions: 18% (c1), 26% (c2), 29% (c3), 27% (c4)). This improvement probably reflects the change in pathological classification rather than a change in management. Proportional hazards analysis of grade IV 1993-2007 only (to reduce pathological variation) showed that younger age, frontal lesions, excision, higher RT dose had reduced hazard of death. Interval from surgery to RT had no impact on survival in this series.

Three years of erlotinib in routine practice for non-small cell lung cancer in South East Scotland.

We present a review of 111 patients who were treated over an initial 3-year period with erlotinib. The median treatment time was 68 days and 59% of patients had stopped treatment within the first 3 months. However, 20 patients were on erlotinib for more than 12 months. Performance status and smoking history were the significant prognostic factors. The overall 3-year survival in patients who had never smoked was 26%.

Non-small-cell lung cancer dimensions: CT-pathological correlation and interobserver variation.

The aim of the study was to identify the most accurate CT window level setting for the measurement of non-small-cell lung cancer to optimise CT planning for radiotherapy treatment. 27 patients who underwent resection for non-small-cell lung cancer in a single institution were studied. The maximal superior-inferior, anteroposterior and mediolateral dimensions of the resected tumours were measured by a consultant pathologist. Two radiologists made corresponding measurements using pre-operative CT scans independently of each other and of the pathologist's findings. The measurements were obtained using four different CT window settings. The mean pathological size of the superior-inferior tumours, the anteroposterior tumours and the mediolateral tumours was 32 mm, 28 mm and 25 mm, respectively. A total of 648 CT measurements were taken, of which 321 were within +/-5 mm of the pathological size (49.5%). There was significant interobserver variability between the two radiologists. There was poor correlation between the pathological and radiological measurements of tumour size. Significant interobserver variability was noted between the two radiologists and no window setting could be identified as being superior in accurately assessing the tumour size.

Improving outcomes for limited stage small cell lung cancer patients in Scotland with concomitant chemoradiation.

AIMS: To determine whether the introduction of early concomitant chemoradiotherapy for patients with limited stage small cell lung cancer (LS-SCLC) has resulted in acceptable outcomes and toxicity in a UK practice. MATERIALS AND METHODS: The case records of all patients with LS-SCLC treated with chemoradiotherapy from July 2001 to 2004 were reviewed, and subjected to descriptive statistics and proportional hazards analysis. RESULTS: Concomitant chemoradiotherapy was delivered to 30 patients and sequential chemoradiotherapy was delivered to 36 patients. The former patients tended to be younger (mean 58.9 vs 64.1 years, P=0.01); the latter patients tended to have bulkier disease. There was no difference in performance status, but cisplatin was given more often in the former group (90% vs 44%, P<0.0001). Grade 3 acute oesophagitis occurred in less than 10% of either group and there were no cases of grade 3 or greater pneumonitis. Two-year actuarial survival for the concomitant group was 53% (95% confidence interval 36-71%) and 36% (95% confidence interval 20-52%) for the sequential group (P=0.018). Proportional hazards analysis showed an increased hazard of death with increasing performance status and age, sequential therapy and the use of cisplatin with sequential therapy. CONCLUSION: Concomitant chemoradiotherapy can be safely given in a UK population with outcomes comparable with those reported in North American series.

Symptom control and quality of life in people with lung cancer: a randomised trial of two palliative radiotherapy fractionation schedules.

AIMS: To determine whether palliation of chest symptoms from a 10 Gy single fraction (regimen 1) was equivalent to that from 30 Gy in 10 fractions (regimen 2). MATERIALS AND METHODS: Patients with cytologically proven, symptomatic lung cancer not amenable to curative therapy, with performance status 0-3, were randomised to receive either 30 Gy in 10 fractions or a 10 Gy single fraction. Local symptoms were scored on a physician-assessed, five-point categorical scale and summed to produce a total symptom score (TSS). This, performance status, Hospital Anxiety and Depression (HAD) score and Spitzer's quality-of-life index were noted before treatment, at 1 month after treatment and every 2 months thereafter. Palliation was defined as an improvement of one point or more in the categorical scale. Equivalence was defined as less than 20% difference in the number achieving an improvement in the TSS. RESULTS: We randomised 149 patients and analysed 74 in each arm. According to the design criteria, palliation was equivalent between the two arms. TSS improved in 49 patients (77%) on regimen 1, and in 57 (92%) patients on regimen 2, a difference of 15% (95% confidence interval [CI] 3-28) in the proportion improving between the two regimens. A complete resolution of all symptoms was achieved in three (5%) on regimen 1, and in 14 (23%) patients on regimen 2 (P < 0.001), a difference in the proportion between the two regimens of 21% (95% CI 10-33). A significantly higher proportion of patients experienced palliation and complete resolution of chest pain and dyspnoea with regimen 2. No differences were observed in toxicity. The median survival was 22.7 weeks for regimen 1 and 28.3 weeks for regimen 2 (P = 0.197). CONCLUSIONS: Although this trial met the pre-determined criteria for equivalence between the two palliative regimens, significantly more patients achieved complete resolution of symptoms and palliation of chest pain and dyspnoea with the fractionated regimen.
