Long-term cancer survival is increasing and, as a consequence, so is the prevalence of secondary malignancies. This study evaluated the patient and tumour characteristics of 117 patients with multiple primary malignant neoplasms (MPMN). The incidence of MPMN in children and adults was 0.28% and 1.23%, respectively. The male : female ratio was 1.7 : 1. The mean ± SE age at tumour diagnosis was 60.56 ± 1.18 years. Overall, the top three tumour sites were the larynx, bladder and breast. Among secondary tumours, lung cancer was the most frequent, followed by breast and colon cancer. Among males, the leading primary and secondary tumour sites were the larynx (30.1%) and lung (50.7%), respectively. Among females, the breasts were both the leading primary (32.6%) and secondary (37.2%) cancer site. The mean ± SE overall survival was 97.2 ± 15.0 months. During follow-up, the brain was the most commonly observed site of metastasis. The occurrence and characteristics of MPMN reported in the literature are also reviewed. The present study contributes towards increasing understanding and treatment of MPMN in a different population group.

The radioprotective effect of lycopene against liver damage was investigated in 80 female Sprague Dawley rats (10 per group). Early-group rats included: controls (group 1), lycopene (group 2), radiotherapy alone (group 3), and lycopene + radiotherapy (group 4). Lycopene (5 mg/kg per day) was administered orally for 7 days; single-fraction 8 Gy abdominopelvic radiotherapy was administered on day 8. Early-group rats were sacrificed on day 10. Late-group rats (groups 5-8) underwent treatment with the same regimens but, in groups 6 and 8, lycopene was administered until all rats were sacrificed, 60 days postradiotherapy. Liver malondialdehyde levels increased significantly and glutathione (GSH) levels, GSH-peroxidase (GSH-Px) and superoxide dismutase (SOD) activity decreased significantly in radiotherapy versus control groups. In lycopene + radiotherapy groups, malondialdehyde levels decreased significantly and GSH levels, GSH-Px and SOD activity increased significantly compared with radiotherapy groups. No significant between-group histo pathological differences were observed in early groups; in late groups, histopathological changes increased significantly in the radiotherapy group versus control group. A significant decrease in histopathological changes occurred in the lycopene + radiotherapy group compared with the radiotherapy group. Lycopene supplementation significantly reduced radiotherapy-induced oxidative liver injury.

The aim of this study was to investigate the frequency with which cancer patients engage in religious and spiritual practices, the methods used, the reasons for such a search, and the levels of depression and hopelessness in patients who seek spiritual assistance. One hundred and ten radiation oncology patients, who gave voluntary informed consent were included in this study. Questionnaires about religious and spiritual practices were administered, along with the Beck Depression and Beck Hopelessness scales. Twenty percent of the patients preferred spiritual practices. Female gender, lower education levels, and higher depression and hopelessness scores were associated with this preference. The frequency of depression was 18.2%, and the frequency of hopelessness was 20.9%. A significant number of cancer patients engaged in religious and spiritual practices. We recommend that practitioners offer their patients brief but sufficient information about religious and spiritual support and determine their patients' depression and hopelessness levels.

BackgroundThe concept of genetic factors playing a role in the pathogenesis of lung cancer has gained increased attention. The present study was undertaken to examine the question of HLA association with lung cancer and to investigate the effects of HLA on survival time.MethodsThe distribution of HLA class I (A, B, C) antigens and class II (DR, DQ) alleles were studied in 81 unrelated Turkish patients with lung cancer. The HLA status of patients was compared with that of a control group consisting of 117 ethnically matched healthy donors. HLA class I antigens were studied by Terasaki’s microlymphocytotoxicity test and HLA class II alleles were studied by polymerase chain reaction with the sequence specific primer (PCR-SSP) low resolution method.ResultsOnly the frequencies of HLA-B51 and -DRB1 *15 were lower in the lung cancer group compared with the healthy control patients. In a univariate analysis, age (P=0.03), Karnofsky Performance Status (P=0.0001 ), stage (P=0.01), HLA A24(9) (P=0.008), HLA B53 (P=0.0006), HLA B63(15) (P=0.01), HLA B64(14) (P=0.01), HLA B65(14) (P=0.01) and HLA CW5 (P=0.01) were significant prognostic factors. In a multivariate analysis, Karnofsky Performance Status (P=0.001), stage (P=0.02), HLA B53 (P=0.03) and HLA B64(14) (P=0.03) were independent prognostic variables.ConclusionsThis study demonstrates different HLA types among patients with lung cancer and healthy control subjects. Our results suggest that HLA antigens might affect the prognosis in lung cancer. Further investigations are warranted to delineate any possible role of the HLA system in the pathogenesis and prognosis of lung cancer.
