Abstract
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.

Abstract
We have analysed the predictive and prognostic information in preoperatively collected serum levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in patients clinically evaluated as operable non-small cell lung cancer (NSCLC). Fifty-eight patients with operable NSCLC were included. VEGF and bFGF levels in serum were analysed using enzyme linked immunosorbent assays (Quantikine human VEGF and Quantikine HS human FGF basic, R&D Systems). Univariate analysis demonstrated that tumour volume, platelet counts, VEGF and bFGF were significant prognostic factors. However, only bFGF remained significant in the multivariate analysis (P=0.014). Significant correlation's were demonstrated between VEGF levels and tumour volume (r=0.33; P=0.012) and platelet count (r=0.43; P=0.001). bFGF levels correlated significant with recurrent disease (r=0.34; P=0.01), platelet count (r=0.53, P<0.001) and performance status (r=0.29; P=0.029). Furthermore, bFGF levels and VEGF levels correlated significantly (r=0.44; P<0.001). We conclude that elevated circulating angiogenic cytokines correlate with tumour volume, higher relapse risk and poorer survival in patients with operable non-small cell lung cancer.

Abstract
BACKGROUND Fluorometric microculture cytotoxicity assay (FMCA) is a short-term semi-automatic method, based on dye-inclusion of surviving cells. The assay was developed for investigations of drug resistance on tumour cells from biopsy material. In the present study, this short-term assay was evaluated, regarding usefulness in determining radio-sensitivity. MATERIALS AND METHODS Eight human lung cancer cell lines were used. There were five small cell lung cancer (SCLC and three non-small cell lung cancer (NSCLC cell lines. Results were compared with the corresponding data derived from the clonogenic assay and/or the extrapolation method. RESULTS The surviving fraction (SF) after 2, 5 and 10 Gy compared with data from the clonogenic assay were not in accordance for 5 of the 8 cell lines. The FMCA assay overestimated SF- values for the SCLC cell lines. CONCLUSION The FMCA assay is not useful as a quick screening method for the radioresponsiveness in vitro of human tumour cell lines.

Abstract
BACKGROUND Oesophageal carcinoma is one of the more aggressive cancers and the patients usually seek medical attention only when the disease is already advanced. Therefore it is important to have a tool, which is simple and fast, to measure and to predict the prognosis for these patients. Mutations in the p53 gene are among the most common genetic abnormalities in oesophageal carcinoma. The present study is the first study, to our knowledge, in which the relationship between the presence of p53 autoantibodies in the serum and survival has been investigated in patients with oesophageal carcinoma. PATIENTS AND METHODS Serum from patients with oesophagal carcinoma was collected between 1996 and 1999 at the Department of Oncology, Uppsala University Hospital, Sweden. The serum samples were analysed for the presence of p53 autoantibodies using a sandwich ELISA. RESULTS In a multivariate analysis, the presence of p53 autoantibodies was associated with decreased survival (p=0.047). Patients with extensive disease had a poor prognosis and time to death was decreased in these patients (p=0.000022). The one-year survival was 0% for these patients if they had p53 autoantibodies compared to 36% for patients with no p53 autoantibodies and extensive disease. CONCLUSION We conclude that the presence of serum p53 autoantibodies is associated with decreased survival for patients with oesophageal carcinoma.

Abstract
BACKGROUND Micronuclei arise from chromosomal, acentric, fragments or whole chromosomes that are not incorporated into the daughter nuclei at mitosis. The micronuclei assay is technically simple and requires only one mitosis in order to obtain information concerning the amount of micronuclei. This study was performed to investigate whether the formation of micronuclei could be used as a marker for intrinsic radiation sensitivity in lung cancer patients. MATERIALS AND METHODS Two human lung cancer cell lines, a non-small cell lung cancer (NSCLC) cell line (U-1810) and a small cell lung cancer (SCLC) cell line (U-1906L), were used. Radiosensitivity data on the survival fraction at 2 Gy were obtained from the clonogenic assay. Radiation was delivered as one-fraction doses: 0, 1, 2, 4, 10 and 20 Gy. After irradiation, the cells were incubated for 0, 24, 48, 60, 72 and 96 hours before fixation and staining. RESULTS The frequency of micronuclei in U-1906L was clearly elevated after 96 hours in the 20 Gy fraction. The frequency of micronuclei reached 5.5%. For U-1810 the micronuclei had a peak clearly different than the other settings after 48 hours in the 10 Gy fraction. The frequency of micronuclei was 1.2%. CONCLUSION Counting micronuclei is not sensitive enough for estimation of radiosensitivity in clinical doses. However, our results demonstrated a distinct difference between NSCLC and SCLC cell lines at higher doses. This difference might be due to different repair fidelity, so future studies with this assay should aim to investigate this hypothesis.

Abstract
BACKGROUND In locally advanced non-small cell lung cancer (NSCLC), studies demonstrating advantages with hyperfractionated accelerated radiotherapy versus conventional radiotherapy have been published, so have studies demonstrating the value of chemotherapy concomitantly with radiotherapy. However, the value of non-conventional fractionation together with concomitant chemotherapy has not been investigated. MATERIALS AND METHODS Consecutive patients from a single institution were studied in a retrospective non-randomised fashion. Inclusion criteria were stage III NSCLC, treatment with curative intent and a total dose above 50 Gy. RESULTS Eighty-two patients were included and further divided into four different treatment groups. Multivariate analysis indicated a survival advantage with non-conventional radiotherapy (NCRT), especially if combined with concomitant chemotherapy. Toxicity was feasible, however there was a trend towards higher toxicity, mainly esophagitis, in patients given concomitant chemotherapy with NCRT. CONCLUSION Our results suggest that accelerated hyperfractionated radiotherapy with concomitant chemotherapy could be an interesting test-arm in a future prospective study.

Abstract
We have developed a method to isolate and analyze nascent human reticulocytes in peripheral blood for the presence of micronuclei (MN). For a very short time peripheral reticulocytes show residual expression of the transferrin receptor. Using immunomagnetic separation of cells expressing the transferrin receptor, a population of immature reticulocytes (Trf-Ret) was isolated from peripheral blood. In humans, the spleen actively removes micronucleated erythrocytes but during the short lifetime of the isolated Trf-Ret only a fraction (less than about 20%) of the MN-containing reticulocytes will have been eliminated. Cells were stained with the fluorescent dyes Thiazole Orange for RNA and Hoechst 33342 for DNA and analyzed by flow cytometry and fluorescence microscopy. Baseline frequencies of MN-Trf-Ret on a group of healthy donors were found to be 1.1% for males and 1.4% for females; however, the gender difference was not significant. The frequency of MN-Trf-Ret in the studied group increased with age, and was dependent on blood group. In three donors studied over 4 months, the baseline level remained stable. In cancer patients treated with radiation or chemotherapy, the frequency of MN-Trf-Ret increased 10- to 20-fold after 1-4 days, depending on the treatment. A high correlation between flow and manual analysis of MN-Trf-Ret was seen. We believe the method has a high potential as a sensitive and rapid method for biological monitoring in presumed exposed groups and individuals.

Abstract
BACKGROUND In this study we investigated if the newly developed monoclonal antibodies against Cytokeratin 8 and 18 fragments (Cyk 8/18) have prognostic information in patients with non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Serum from 69 patients with NSCLC was investigated using a sandwich ELISA, Cyk 8/18, provided by IDL Biotech, Sollentuna Sweden. RESULTS Cyk 8/18 levels varied between 0.34-14.2 ng/mL, compared with a cut-off value of 1.0 ng/mL for healthy individuals (95% specificity). Using that cut-off value, 80% of NSCLC patients had elevated levels. A statistically significant diminished survival was found for Cyk 8/18 values of 8.0 ng/mL or higher (p = 0.0001). When survival data and Cyk 8/18 levels were analysed according to continuous Cox regression analysis, increased levels of Cyk 8/18 were significantly related to decreased survival (p = 0.016). CONCLUSIONS The Cyk 8/18 monoclonal antibody had in this study prognostic information regarding survival in patients with NSCLC.

Abstract
The purpose of this study was to analyse objective modalities of ankle joint function after an acute ankle sprain and to see whether treatment with an air-cushioned ankle brace could enhance the restoration of function compared with a traditionally used compression bandage. The study included 73 consecutive patients between 15 and 55 years of age with an acute grade II or III ankle sprain, who sought medical care within 24 h of the time of injury. Patients with recurrent sprain were excluded. The patients were allocated at random to treatment with compression bandage or an air-cushioned ankle brace (Air-Stirrup, Aircast). The regimen included early motion and weight-bearing in both groups. The patients were examined initially within 24 h, after 3-5 days, 2, 4 and 10 weeks after the injury by the following tests: clinical examination including range of motion, recording of postural sway by stabilometry, joint position sense test, isokinetic eversion-inversion muscle torques and figure-of-eight running. A decreased active range of motion in eversion-inversion was observed during the entire follow-up period. Increased postural sway was registered when standing on the injured foot up to 4 weeks after the injury, as were a deficit in evertor muscle peak torque and an evertor-invertor muscle imbalance compared with the uninjured side. Women demonstrated a greater impairment in postural sway than men. A longer curve running time with the injured ankle at the outside of the curve was noted at the 10-week follow-up. With the exception of running in a figure of eight, these measures were not influenced by treatment with a semi-rigid ankle brace. The methods used in the present study are well suited for further studies of objective modalities of ankle joint function, with the possible exception of the joint position sense test.

Abstract
In this study the entire p53 complementary DNA has been sequenced in 20 non-small cell lung carcinomas (NSCLC) and the results correlated with chemosensitivity, immunohistochemistry and clinical data. Ten patients had mutations in p53, 8 missense mutations and 2 nonsense mutations. The method discovered two mutations never described previously and two other mutations that have never been described before in connection with NSCLC tumours. Chemosensitivity data, according to a short-term assay (FMCA), indicated that tumours with p53 mutation were more resistant to cisplatin and cyclophosphamide. Immunohistochemical studied demonstrated a 70% concordance between over-expression of p53 protein and mutation in p53. No conclusions or trends could be drawn from the immunohistochemical studies of Bcl-2 and Bax.

Abstract
Using the comet assay, radiation-induced DNA strand breaks were evaluated in human lung cancer cell lines with different radiosensitivity (U-1285, U-1906E, U-1752 and U-1810). Single strand breaks were more sensitive indicators of the radiation-induced damage than double strand breaks. However, there was no consistent pattern in the way the various cell lines responded to 1-5 Gy of gamma-irradiation and all cell lines showed a remarkably efficient DNA repair after 1 h. In a separate study of the repair kinetics of DNA double strand breaks, the radioresistant cell line U-1810 showed a more efficient initial strand rejoining than the radiosensitive cell line U-1285 after irradiation at 2 Gy. The latter finding suggests that the detection of early DNA repair may be useful when monitoring the intrinsic radiosensitivity of human lung cancer cells.

Abstract
BACKGROUND In this study we investigated whether the presence of p53 antibodies in sera before of during/after radiation therapy can predict increased survival in patients with non-small cell lung cancer. PATIENTS AND MATERIALS Sera from 67 patients with a histopathologically confirmed diagnosis of nonsmall cell lung cancer have been investigated using sandwich ELISA (Dianova, Hamburg, Germany). Sera was collected before or during/after radiation therapy. RESULTS Antibodies were detected in 18 (27%) patients. 46/67 (69%) of the sera had been taken before start of radiation therapy and the presence of p53 antibodies was a statistically significantly good prognostic factor in terms of increased survival (p = 0.025). CONCLUSION p53 antibodies in sera, before the start of radiation therapy, can predict increased survival after radiation treatment in patients with non-small cell lung cancer.

Abstract
A total of 94 patients with brain metastases from lung carcinomas were treated with irradiation of their brain metastases. Two fractionation schedules were applied, a non-conventional one (76 patients) mixing hypofractionation and accelerated hyperfractionation to a total dose of 47 Gy and a conventional one (18 patients), with 3 Gy once a day to a total dose of 30 or 36 Gy. No benefit was found for the non-conventional treatment schedule over the conventional one. A difference in survival was demonstrated between patients whose brain metastases originated from adenocarcinoma or squamous cell carcinoma of the lung with a median survival of 3.5 and 1.9 months, respectively (P = 0.006). Median survival of patients with brain metastases from small cell lung cancer (SCLC) was 2.8 months, and when compared with the squamous cell carcinoma group, there was no statistically improved survival (P = 0.12). There were indications of a better palliative effect in adenocarcinomas compared with squamous or large cell carcinomas. In a few patients (1/22 adenocarcinoma and 7/32 SCLC), the patients were free from malignant cells in the brain at autopsy, demonstrating that irradiation of brain metastases might be efficient in certain patients.

Abstract
BACKGROUND The formation of new microvessels from the existing vascular bed is known as angiogenesis and is normally under the tight regulatory control of angiogenic factors. This control is lost in malignant tumours. Previous studies have correlated increased microvessel density with poor prognosis in patients with primary lung cancer. MATERIALS AND METHODS Our group measured levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in sera from 68 patients with non-small cell lung cancer (NSCLC) and compared elevated levels of VEGF and bFGF with clinical outcome. Serum basic FGF and VEGF were measured using commercially available enzyme- linked immunosorbent assays (R & D Systems Inc., Minneapolis, MN USA). RESULTS In 26/68 (38%) patients we found that elevated circulating levels of bFGF and in 27/68 (39%) serum samples levels of VEGF were elevated. Elevated bFGF values in sera was a statistically significant good prognostic factor, p- value = 0.048, when adjusted to stage and there was a trend in that patients with elevated levels of bFGF had a higher fraction of adenocarcinomas compared with squamous epithelial carcinomas (chi 2 = 2.0). No significant correlations could be demonstrated when elevated levels of VEGF in serum was present. Elevated levels of both VEGF and bFGF was present in 45% of the patients. CONCLUSIONS We found that elevated levels of bFGF is a good prognostic factor when measured in sera from NSCLC patients. As this result disagrees with earlier studies on other malignancies the results from our study needs to be further investigated in a prospective study.
