METHODS: A cross-sectional study design with 113 colorectal cancer survivors (from two large public hospitals in Malaysia) was conducted. Data collection tools included the Occupational Participation Questionnaire, Engagement in Meaningful-activities, and the European Organization for Research and Treatment in Cancer Quality of Life (QOL) Questionnaire. Data analyses were conducted using SmartPLS to examine path analyses between the three measures.
RESULTS: There were independent significant relationships between (1) occupational participation, and (2) meaningful activity engagements on the dependent variable of QOL in this cohort of cancer survivors. More importantly, the result showed that "meaningful-activity" positively and significantly mediates the path between occupational participation and quality of life [β = 0.250 (0.46*0.59), ρ
CASE REPORT: We report a rare case of primary uterine angiosarcoma with unusual rhabdoid morphology in a 41-year-old female, who underwent radical hysterectomy and died of disease after 4 months of treatment.
DISCUSSION: We described the differential diagnosis of primary angiosarcoma of the uterus that can pose a diagnostic challenge.
METHODS: Immunoblotting, immunofluorescence, quantitative real-time PCR and flow cytometry assays investigated the expression of E-cadherin and CXCR3 isoforms. Intrasplenic inoculation of human prostate cancer (PCa) cells with spontaneous metastasis to the liver analyzed E-cadherin and CXCR3-B expression during cancer progression in vivo.
RESULTS: We found reciprocal regulation of E-cadherin and CXCR3 isoforms. E-cadherin surface expression promoted CXCR3-B presentation on the cell membrane, and to a lesser extent increased its mRNA and total protein levels. In turn, forced expression of CXCR3-A reduced E-cadherin expression level, whereas CXCR3-B increased E-cadherin in PCa. Meanwhile, a positive correlation of E-cadherin and CXCR3-B expression was found both in experimental PCa liver micro-metastases and patients' tissue.
CONCLUSIONS: CXCR3-B and E-cadherin positively correlated in vitro and in vivo in PCa cells and liver metastases, whereas CXCR3-A negatively regulated E-cadherin expression. These results suggest that CXCR3 isoforms may play important roles in cancer progression and dissemination via diametrically regulating tumor's phenotype.
