RESUMO

Objective To investigate the standardized treatment of 33 children with thalassemia and their family financial burden registered in Bao'an district, Shenzhen city, and to provide basic information for formulating health policy for the government. Methods In 2009, preliminary investigations on 39 registered families with thalassemia children were conducted by telephone, and a household survey was made to collect treatment and economic status by questionnaire on 33 children. Results Among 33 cases of thalassemia children, 21 cases(63.7%) were severe anemia, 5 cases( 15.1%) in need of care or special care, and 25 cases(75.8%) were difficult or unable to maintain standardized treatment. The average family monthly income and expenditure was (4060 ± 2002) and (4926 ± 2991) yuan, respectively. The average monthly treatment costs were (2665 ± 1872) yuan, and the average debt amounted to (64 600 ± 53 940) yuan. Fifteen families[60.0%(15/25)] would reduce the times of blood transfusions or iron transpirations when they encountered revenue deficiency. Conclusions The heavy economic burdens on families with children thalassemia result in inadequate or interrupted treatment on sick children and affect their survival and quality of life, which should be taken more attention and social care.

RESUMO

<p><b>OBJECTIVE</b>The phosphatidylinositol-3-kinase (PI3K)-AKT signaling pathway is considered to play an important role in tumorigenesis. Frequent somatic mutations in the PI3K subunit p110a (PIK3CA) occur in a variety of cancer types. The purpose of this study was to determine the relationship between PIK3CA mutation in breast cancer and pathological features and outcome of patients.</p><p><b>METHODS</b>The PIK3CA mutations in exons 7, 9, 20 were screened in 250 primary breast cancers using PCR and fluorescent (F)-SSCP, and the results were analyzed according to their cliniopathological data.</p><p><b>RESULTS</b>The frequency of PIK3CA mutations among the 250 cases was 35.2% (88/250), point mutations in exon 7 were found in 8 (3.2%) cases,40 (16.0%) cases in exon 9 and 47 (18.8%) cases in exon 20. No significant correlation between PIK3CA mutation and age, histological type, differentiation, and lymph node metastasis was observed. Mutations were associated with larger tumor size (P = 0.004) and positive estrogen receptor status (P = 0.008). Patients with PIK3CA mutations showed a significantly worse survival (P = 0.004), particularly in those with positive estrogen receptor expression or non-amplified HER-2 (both P = 0.002).</p><p><b>CONCLUSIONS</b>PIK3CA mutations may play an important role in the carcinogenesis and development of breast cancer. The association with large tumor size, ER+ and poor survival indicates that PIK3CA mutation could be an independent factor for tumor malignant phenotype and prognosis.</p>
