    • Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) have both been implicated to have roles in tumour angiogenesis. In the present retrospective study, serum VEGF and bFGF from patients with locally advanced non-small cell lung cancer (NSCLC) were analysed before, during and after treatment. Seventy-three patients and a total of 460 serum samples were analysed for VEGF and 443 serum samples were analysed for bFGF. Pre-treatment bFGF levels in patients with normal platelet counts, were correlated to poorer survival, P-value = 0.047. During chemotherapy, each rise of one unit bFGF corresponded to a hazard ratio of 4.06 (P=0.022). In patients with normal platelet counts, VEGF levels after radiotherapy significantly correlated to good prognosis (P=0.023), during radiotherapy VEGF levels indicated the same correlation (P=0.085). We conclude that serum VEGF and especially bFGF are of clinical interest as prognostic factors, especially in patients presenting with normal platelet counts.

  • Concurrent cetuximab and radiotherapy after docetaxel-cisplatin induction chemotherapy in stage III NSCLC : Satellite-A phase II study from the Swedish Lung Cancer Study Group
  • 2011
  • Ingår i: Lung Cancer. - : Elsevier BV. - 0169-5002 .- 1872-8332. ; 71:2, s. 166-172

    • Background: Several attempts to increase the locoregional control in locally advanced lung cancer including concurrent chemotherapy, accelerated fractionation and dose escalation have been made during the last years. As the EGFR directed antibody cetuximab has shown activity concurrent with radiotherapy in squamous cell carcinoma of the head and neck, as well as in stage IV NSCLC combined with chemotherapy, we wanted to investigate radiotherapy with concurrent cetuximab in locally advanced NSCLC, a tumour type often over expressing the EGF-receptor. Methods: Between February 2006 and August 2007 75 patients in stage Ill NSCLC with good performance status (PS 0 or 1) and adequate lung function (FEV1 > 1.0) were enrolled in this phase II study at eight institutions. Treatment consisted of 2 cycles of induction chemotherapy, docetaxel 75 mg/m(2) and cisplatin 75 mg/m(2) with 3 weeks interval. An initial dose of cetuximab 400 mg/m(2) was given before start of 3D-CRT to 68 Gy with 2 Gy per fraction in 7 weeks concurrent with weekly cetuximab 250 mg/m(2). Toxicity was scored weekly during radiotherapy (CTC 3.0), and after treatment the patients were followed every third month with CT-scans, toxicity scoring and QLQ. Results: Seventy-one patients were eligible for analysis as four were incorrectly enrolled. Histology: adenocarcinoma 49%, squamous cell carcinoma 39% and other NSCLC 12%. The majority had PS 0 (62.5%), median age 62.2 (42-81), 50% were women and 37% had a pre-treatment weight loss > 5%. Toxicity: esophagitis grade 1-2: 72%; grade 3:1.4%. Hypersensitivity reactions grade 3-4: 5.6%. Febrile neutropenia grade 3-4: 15.4%. Skin reactions grade 1-2: 74%; grade 3: 4.2%. Diarrhoea grade 1-2: 38%; grade 3: 11.3%. Pneumonitis grade 1-2: 26.8%; grade 3: 4.2%; grade 5:1.4%. The median follow-up was 39 months for patients alive and the median survival was 17 months with a 1-, 2- and 3-year OS of 66%, 37% and 29% respectively. Until now local or regional failure has occurred in 20 patients and 22 patients have developed distant metastases. Weight loss, PS and stage were predictive for survival in univariate as well as in multivariate analysis. Conclusion: Induction chemotherapy followed by concurrent cetuximab and RT to 68 Gy is clearly feasible with promising survival. Toxicity, e.g. pneumonitis and esophagitis is low compared to most schedules with concurrent chemotherapy. This treatment strategy should be evaluated in a randomised manner vs. concurrent chemoradiotherapy to find out if it is a valid treatment option.

  • Regional differences in treatment and outcome in non-small cell lung cancer : a population-based study (Sweden)
  • 2009
  • Ingår i: Lung Cancer. - : Elsevier BV. - 0169-5002 .- 1872-8332. ; 63:1, s. 16-22
  • Tidskriftsartikel (refereegranskat)abstract
    • In the recent decade uniform treatment guidelines for non-small cell lung cancer (NSCLC) have been introduced in Sweden. The objective of this study was to examine time trends and differences in treatment intensity for NSCLC between county clinical centres in Central Sweden. A second aim was to investigate whether any differences in treatment of NSCLC were associated with differences in survival. 4345 patients with a diagnosis of NSCLC between 1995 and 2003 were identified in the population-based Lung Cancer Register of Central Sweden. Multivariate logistic regression was used to estimate odds ratios to analyse the likelihood of receiving different treatment modalities for NSCLC. Cox proportional hazard models estimating relative hazard ratios were used to identify factors related to death (by any cause). Of all patients, 33.4% received no treatment, and 17.5% underwent surgery. Between 1995 and 2003, the proportion of patients receiving chemotherapy rose from 14.6% to 55%. There were pronounced differences between county centres in treatment policies, especially concerning surgery and radiotherapy. The likelihood of receiving treatment for NSCLC was highest at county centre A where both surgical treatment and chemotherapy were given more often. Compared to this reference county, the risk of death was between 20% and 40% higher in the other counties after adjusting for age, stage, gender, time period, smoking status and histopathological type. When analyses were adjusted for treatment, county of residence was no longer a prognostic factor. Despite common guidelines there were marked differences in treatment activity between the counties. Treatment activity was associated with survival. Survival benefits may follow improvement in compliance to guidelines.

  • Educational level and management and outcomes in non-small cell lung cancer. A nationwide population-based study
  • 2019
  • Ingår i: Lung Cancer. - : ELSEVIER IRELAND LTD. - 0169-5002 .- 1872-8332. ; 131, s. 40-46
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: We examined associations between educational level and clinical presentation, patterns of management and mortality in patients with non-small cell lung cancer (NSCLC) in Sweden, a country with a National Health Care System. Materials and Methods: We identified 39,671 patients with a NSCLC diagnosis 2002-2016 in Lung Cancer Data Base Sweden (LCBaSe), a population-based research database. In analyses adjusted for comorbidity and other prognostic factors, odds Ratios (OR) and hazard Ratios (HR) were estimated to examine associations between patients' educational level and aspects of management and mortality. Results: Stage at diagnosis and waiting times did not differ between educational groups. In multivariable analysis, the likelihood to undergo PET/CT and assessment in a multidisciplinary team setting were higher in patients with high compared to low education (aOR 1.14; CI 1.05-1.23 and aOR 1.22; CI 1.14-1.32, respectively). In patients with early stage IA-IIB disease, the likelihood to undergo stereotactic radiotherapy was elevated in patients with high education (aOR 1.40; CI 1.03-1.91). Both all-cause (aHR 0.86; CI 0.77-0.92) and cause specific mortality (aHR 0.83; CI 0.74-0.92) was lower in patients with high compared to low education in early stage disease (IA-IIB). In higher stage NSCLC no differences were observed. Patterns were similar in separate assessments stratified by sex and histopathology. Conclusions: While stage at diagnosis and waiting times did not differ between educational groups, we found socioeconomic differences in diagnostic intensity, multidisciplinary team assessment, stereotactic radiotherapy and mortality in patients with NSCLC. These findings may in part reflect social gradients in implementation and use of novel diagnostic and treatment modalities. Our findings underscore the need for improved adherence to national guidelines.
