RESUMO

BACKGROUND: Although locally advanced breast cancer (LABC) is more common in the elderly population, there is little data on the clinical characteristics and survival of these patients. The aim of the present study was to compare different factors affecting survival in elderly patients with LABC. METHODS: Retrospective analysis was carried out on a cohort of 80 patients aged 70 to 96 years, diagnosed with LABC defined as T3 N1, T4 N0, any N2 or N3, and M0. The prognostic impact of selected clinical parameters including age, comorbidities, tumour grade, HER2 status, tumour stage, local therapies, and systemic treatments was studied. RESULTS: The median age of the patients was 79 years. The majority (n=53; 66%) had at least one significant comorbidity according to the Charlson score evaluation. The median overall survival was 50.6 months. As expected, hormonal therapy was the dominant mode of systemic treatment, but 24% also received at least one line of chemotherapy. Local therapies including surgery and/or radiotherapy were applied in 58% of patients. CONCLUSIONS: The diagnosis of LABC in the elderly is associated with poor prognosis. Age and serious comorbidities were negative prognostic factors.

RESUMO

 Introduction and aim. Hepatocellular carcinoma (HCC) is the most common primary malignant liver tumor. It is primarily caused by hepatic cirrhosis or chronic viral hepatitis. Hepatic carcinogenesis is associated with increased oxidative stress. Thus, the aim of our study was to assess expression of the genes involved in the homeostasis of oxidative stress in patients with HCC. MATERIAL AND METHODS: The study was performed on 32 patients with primary HCC (verified by liver histology in 29 patients) and 27 control subjects (in 11 subjects, liver histology was available either with no or minimal changes in the liver tissue). Gene expressions of heme oxygenase 1 (HMOX1), biliverdin reductase A/B (BLVRA/B), NADPH oxidase 2 (NOX2) and p22phox were analyzed in the liver and peripheral blood leukocytes (PBL) in the subjects. RESULTS: Compared to controls, almost a 3 times higher mRNA level of BLVRA was detected in livers of HCC patients (p = 0.002); while those of BLVRB as well as HMOX1 were unchanged (p > 0.05). In accord with these results in the liver tissue, BLVRA mRNA levels in PBL were also significantly increased in HCC patients (p = 0.012). mRNA levels of NOX2 and p22phox in the liver tissue, although higher in HCC patients, did not differ significantly compared to control subjects (p > 0.05). Nevertheless, NOX2 mRNA level in PBL was significantly higher in HCC patients (p = 0.003). CONCLUSIONS: BLVRA mRNA levels in the liver as well as in PBL are significantly higher in HCC patients most likely as a feedback mechanism to control increased oxidative stress associated with HCC progression.

RESUMO

BACKGROUND: Second cancers are an important cause of mortality and morbidity in long-term survivors of testicular germ cell tumors (TGCTs). Studies on the impact of follow-up for the first tumor on the outcome of second malignancies are lacking. The aim of this study was to study the details of diagnosis of second cancers and the role of focused oncology follow-up. METHODS: Medical records and the electronic database of a tertiary referral center for germ cell neoplasms were searched for second cancers diagnosed in TGCT survivors. In a database of 1057 patients, 63 cases of metachronous second malignancies (26 contralateral testicular cancers and 37 nontesticular cancers) were found in 57 patients. Long-term oncology follow-up consisted of yearly history, physical examination, germ cell tumor markers, and imaging including abdominal computed tomography (CT) scans and chest x-ray. RESULTS: The second malignancies occurred after a medium follow-up of 9.9 years (range, 1.1-33 years) after the diagnosis of the first tumor. Only 17 (27%) of the 63 second tumors were detected by oncology follow-up investigations, and a further 12 (29%) were detected by nononcology physicians during a preplanned clinical visit. In 34 (54%) cases, patients themselves or their relatives initiated a clinical appointment because of symptoms. Follow-up investigations all had low yields for the detection of second malignancies, although CT imaging did detect several cases of cancer at an early stage. CONCLUSIONS: In this retrospective study, most second cancers occurring in long-term TGCT survivors were missed by regular oncology follow-up that included yearly physical examination, tumor marker, and imaging.
