Family-oriented care and health-related quality of life for women with gynaecological cancer: A cross-sectional mixed-method study.

AIMS: This study aims to describe the experiences of women with gynaecological cancer regarding family-oriented care (FOC) and how they rated their health-related quality of life (HRQoL) using a 15D instrument (15D©). DESIGN: A cross-sectional mixed-method study. METHODS: The data were collected by electronic surveys of two Finnish cancer associations from gynaecological cancer patients (n = 53). The qualitative data were analysed using thematic analysis. The HRQoL answers were analysed statistically using IBM SPSS Statistics (Version 27). RESULTS: The results emphasized that FOC is not yet part of the care process. Furthermore, comprehensive encounters are lacking, and the experience of being a woman is forgotten during the care process. The results of the HRQoL analysis suggest that distress and the discomfort and symptoms of cancer patients are perceived as significant factors affecting their quality of life during different phases of treatment. Family status also has an impact on perceived quality of life, whereby those living alone gave worse ratings for the depression and vitality dimensions. CONCLUSION: In part, the quantitative and qualitative data supported each other, but the descriptions provided a more comprehensive view of issues that affect women in a more multidimensional way, such as sexual health issues. More research on the effectiveness of FOC is needed to develop the capacity for effective healthcare. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: This study was able to identify important areas for improvement in clinical practice from the perspective of patients and their families. REPORTING METHOD: This study was prepared and reported according to the STROBE checklist. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Microvessels in Epithelial Ovarian Tumors: High Microvessel Density Is a Significant Feature of Malignant Ovarian Tumors.

BACKGROUND/AIM: Examine features of blood and lymphatic vessels in ovarian tumors and their significance to prognosis of ovarian cancer. PATIENTS AND METHODS: A total of 139 women with epithelial ovarian tumors were included: 86 malignant, 17 borderline and 36 benign. Density, percentage, mean size and number of blood microvessels in tumors were measured by immunohistochemistry with antibodies against CD34 and CD105. Lymphatic vessel density was assayed using the D2-40 antibody against podoplanin. RESULTS: Angiogenesis was most profuse in malignant tumors. Small size of lymph vessels predicted 26% shorter 5-year survival of ovarian cancer patients. Further, high percentage of lymphatic vessels in tumors was associated with lymph node metastasis, and high density with cancer recurrence. Lower number of microvessels, as assessed by CD34 staining, predicted shorter progression-free survival. Additionally, the large size of microvessels assessed by CD34 and the high number of vessels assessed by CD105 were related to residual tumor >1 cm at primary surgery and also, large vessel size was associated with stage III, as assessed by CD105 staining. CONCLUSION: CD34 and CD105 define different characteristics of microvessels. Parameters of lymph vessels may predict the prognosis of ovarian cancer.

High expression of Tie-2 predicts poor prognosis in primary high grade serous ovarian cancer.

BACKGROUND: Antiangiogenic therapy, although part of standard treatment in ovarian cancer, has variable efficacy. Furthermore, little is known about the prognostic biomarkers and factors influencing angiogenesis in cancer tissue. We evaluated the expression of angiopoietin-2 and two endothelial tyrosine kinase receptors, Tie-1 and Tie-2, and assessed their value in the prediction of survival in patients with malignant epithelial ovarian cancer. We also compared the expression of these factors between primary high grade serous tumors and their distant metastasis. MATERIALS AND METHODS: We evaluated 86 women with primary epithelial ovarian cancer. Matched distal omental metastasis were investigated in 18.6% cases (N = 16). The expression levels of angiogenic factors were evaluated by immunohistochemistry in 306 specimens and by qRT-PCR in 111 samples. RESULTS: A high epithelial expression level of Tie-2 is a significant prognostic factor in primary high grade serous ovarian cancer. It predicted significantly shorter overall survival both in univariate (p<0.001) and multivariate survival analyses (p = 0.022). Low angiopoietin-2 expression levels in primary ovarian tumors were significantly associated with shorter overall survival (p = 0.015) in the univariate survival analysis. A low expression of angiopoietin-2 was also significantly related to high grade tumors, size of residual tumor after primary surgery and the recurrence of cancer (p = 0.008; p = 0.012; p = 0.018) in the whole study population. The expression of angiopoietin-2 and Tie-2 was stronger in distal omental metastasis than in primary high grade serous tumors in matched-pair analysis (p = 0.001; p = 0.002). CONCLUSIONS: The angiogenic factor, angiopoietin-2, and its receptor Tie-2 seem to be significant prognostic factors in primary epithelial ovarian cancer. Their expression levels are also increased in metastatic lesions in comparison with primary tumors.

Expression profiles of VEGF-A, VEGF-D and VEGFR1 are higher in distant metastases than in matched primary high grade epithelial ovarian cancer.

BACKGROUND: In many malignancies including ovarian cancer, different angiogenic factors have been related to poor prognosis. However, data on their relations to each other or importance as a prognostic factor in ovarian cancer is missing. Therefore, we investigated the expressions of VEGF-A, VEGF-C, and VEGF-D, and the receptors VEGFR1, VEGFR2, and VEGFR3 in patients with malignant epithelial ovarian neoplasms. We further compared expression levels between primary tumors and related distant omental metastases. METHODS: This study included 86 patients with malignant ovarian epithelial tumors and 16 related distant metastases. Angiogenic factor expression was evaluated using immunohistochemistry (n = 102) and qRT-PCR (n = 29). RESULTS: Compared to primary high grade serous ovarian tumors, the related omental metastases showed higher expressions of VEGF-A (p = 0.022), VEGF-D (p = 0.010), and VEGFR1 (p = 0.046). In univariate survival analysis, low epithelial expression of VEGF-A in primary tumors was associated with poor prognosis (p = 0.024), and short progression-free survival was associated with high VEGF-C (p = 0.034) and low VEGFR3 (p = 0.002). The relative expressions of VEGF-D, VEGFR1, VEGFR2, and VEGFR3 mRNA determined by qRT-PCR analyses were significantly correlated with the immunohistochemically detected levels of these proteins in primary high grade serous ovarian cancer and metastases (p = 0.004, p = 0.009, p = 0.015, and p = 0.018, respectively). CONCLUSIONS: The expressions of VEGF receptors and their ligands significantly differed between malignant ovarian tumors and paired distant metastases. VEGF-A, VEGF-D, and VEGFR1 protein expressions seem to be higher in distant metastases than in the primary high grade serous ovarian cancer lesions.

Antiangiogenic gene therapy with soluble VEGF-receptors -1, -2 and -3 together with paclitaxel prolongs survival of mice with human ovarian carcinoma.

We compared effects of antiangiogenic gene therapy with a combination of soluble sVEGFR-1, sVEGFR-2 and sVEGFR-3 to chemotherapy with carboplatin and paclitaxel and to antiangiogenic monoclonal anti-VEGF-antibody bevacizumab in an intraperitoneal ovarian cancer xenograft model in mice (n = 80). Gene therapy was also combined with chemotherapy. Therapy was initiated when sizable tumors were confirmed in magnetic resonance imaging (MRI). Adenovirus-mediated gene transfer was performed intravenously (2 × 109 pfu), while chemotherapy and monoclonal anti-VEGF-antibody were dosed intraperitoneally. The study groups were as follows: AdLacZ control (n = 21); combination of AdsVEGFR-1, -2 and -3 (n = 21); combination of AdsVEGFR-1, -2, -3 and paclitaxel (n = 9); bevacizumab (n = 14); paclitaxel (n = 9) and carboplatin (n = 5). Effectiveness was assessed by survival time and surrogate measures such as sequential MRI, immunohistochemistry, microvessel density and tumor growth. Antiangiogenic gene therapy combined with paclitaxel significantly prolonged the mean survival of mice (25 days) compared to the controls (15 days) and all other treatment groups (p = 0.001). Bevacizumab treatment did not have any significant effect on the survival. Tumors of the mice treated by gene therapy were significantly smaller than in the control group (p = 0.021). The mean vascular density and total vascular area were also significantly smaller in the tumors of the gene therapy group (p = 0.01). These results show potential of the antiangiogenic gene therapy to improve efficacy of chemotherapy with paclitaxel and support testing of this approach in a phase I clinical trial for the treatment of ovarian cancer.
