Endorectal power Doppler ultrasonography is a reliable method for evaluation of rectal cancer angiogenesis.

OBJECTIVE: We aimed to assess the preoperative rectal cancer angiogenesis with Endorectal Power Doppler Ultrasonography by using the Power Doppler Vascularity Index (PDVI) calculated by imaging analysis software, and to compare it with the microvessel density (MVD) in surgical specimens PATIENTS AND METHODS: This study included 110 patients (39 females; mean age 61.5 years) with rectal cancer. Immunohistochemical staining of surgical specimens with anti-CD-31 antibody was used for MVD evaluation. The PDVI of each tumor was calculated using Endorectal Power Doppler with computer-assisted quantification of colour pixels. RESULTS: Mean MVD - 163 ± 69 microvessels/mm2 (50-328) was used as a cutoff point, differentiating two groups of tumors with high (> 160 mm2) and low (≤ 160 mm2) angiogenic activity. Mean PDVI of 8.9 ± 6.0% (0-27.3) was used as a cutoff point, dividing two groups of tumors with high (> 8%) and low (≤ 8%) PDVI. The MVD and the PDVI showed a good positive correlation (r = 0.438, p = 0.002). Patients with low PDVI had 25 months longer overall survival (p < 0.05) than patients with high PDVI. Patients with low MVD had 36 months longer survival (p < 0.05). CONCLUSIONS: Endorectal Power Doppler Ultrasonography is a reliable and noninvasive method for assessment of the extent of rectal cancer angiogenesis. Tumor angiogenesis assessed by the PDVI correlated with histological MVD determination and could predict survival rates. Endorectal Power Doppler examination is a useful and reproducible method for in vivo preoperative quantitative assessment of tumor vascularization.

Patients from across Europe have similar views on patient-centred care: an international multilingual qualitative study in infertility care.

BACKGROUND: International patient centredness concepts were suggested but never conceptualized from the patients' perspective. Previously, a literature review and a monolingual qualitative study defined 'patient-centred infertility care' (PCIC). The present study aimed to test whether patients from across Europe value the same aspects of infertility care. METHODS: An international multilingual focus group (FG) study with 48 European patients from fertility clinics in Austria, Spain, the UK and Belgium, with deductive content analysis. RESULTS: All specific care aspects important to participants from all countries could be allocated to the 10 dimensions of PCIC, each discussed in every FG, including: 'information provision', 'attitude of and relationship with staff', 'competence of clinic and staff', 'communication', 'patient involvement and privacy', 'emotional support', 'coordination and integration', 'continuity and transition', 'physical comfort' and 'accessibility'. Most specific care aspects (65%) were discussed in two or more countries and only a few new codes (11%) needed to be added to the previously published coding tree. Rankings from across Europe clearly showed that 'information provision' is a top priority. CONCLUSIONS: The PCIC-model is the first patient-centred care (PCC) model based on the patients' perspective to be validated in an international setting. Although health-care organization and performance differ, the similarities between countries in the infertile patients' perspective were striking, as were the similarities with PCC models from other clinical conditions. A non-condition specific international PCC model and a European instrument for the patient centredness of infertility care could be developed. European professionals can learn from each other on how to provide PCC.

Preoperative diagnosis of jejunal adenocarcinoma--a case report.

We report herein the case of a preoperatively diagnosed small bowel adenocarcinoma. A 57-year-old man was hospitalized twice for a month in the Gastroenterology Clinic due to complaints lasting a year before hospitalization and consisting of heaviness and spastic pain in the left upper abdomen. None of the numerous methods used in this case (fibrogastroduodenoscopy, ileocolonoscopy, barium series and CT) could reveal a tumor. Ultrasound (US) examination showed a polycyclic formation in the left hypochondrium with enlarged regional lymph nodes. An US-guided fine (20 gauge) needle aspiration (FNA) cytology of the mass was performed and showed moderately differentiated adenocarcinoma of intestinal origin. Thanks to Doppler US guidance during FNA a massive bleeding from an identified arterial vessel with high systolic speed was avoided. On surgical exploration a jejunal tumor of high consistency was found, located 15 cm distantly from the Treitz ligament, infiltrating up to 2/3 of the bowel circumference and partly obstructing its lumen. The histological evaluation of the resected material showed highly to moderately differentiated adenocarcinoma with 5 regional lymph node metastases. The combination of US with Doppler and FNA established preoperatively the malignant small bowel disease.
