Membrane expression of trail receptors DcR1 and DcR2 in the normal endometrium, endometrial atypical hyperplasia and endometrioid endometrial cancer.

We aimed to evaluate the membrane expression of DcR1 and DcR2 in the normal endometrium (NE), endometrial atypical hyperplasia (EAH) and endometrioid endometrial cancer (EEC). The study comprised 101 patients: 20 NE, 14 EAH and 67 EEC. Membrane expression of DcR1 and DcR2 was examined and presented as total score (TS). The membrane expression of both DcR1 and DcR2 was more common in EEC than in NE (p < 0.001; p < 0.001). A strong correlation was found between type of endometrial tissue (NE/EAH/EEC) and the TS of DcR1 (p = 0.001) and DcR2 (p < 0.001). In EEC, the TS of DcR1 and DcR2 was not related to grading and survival. The TS of DcR1 negatively correlated with staging (p = 0.018), but DcR2 did not. The membrane expression of decoy receptors for TRAIL DcR1 and DcR2 is greater in NE than EEC. In EEC patients, membrane expression of DcR1 and DcR2 are not independent predictors of survival.

Membrane expression of the death ligand trail receptors DR4 and DR5 in the normal endometrium, endometrial atypical hyperplasia and endometrioid endometrial cancer.

To assess membrane expression of DR4 and DR5 in the normal endometrium (NE), endometrial atypical hyperplasia (EAH) and endometrioid endometrial cancer (EEC), the study examined 101 patients: 20 NE, 14 EAH and 67 EEC. The expression of DR4 and DR5 was examined and presented as the total score (TS). DR4 expression was seen in 18 NE, 11 EAH and 10 EEC. DR5 expression was seen in 20 NE, 13 EAH and 21 EEC. A strong correlation between type of endometrial tissue and TS of both receptors was identified. In EEC TS of DR4 and DR5 was not related to grading, staging or survival. Malignant transformation in the endometrium is related to reduction of membrane DR4 and DR5 expression. The level of membrane staining of the receptors in EEC is not dependent on grading and staging, and is not sufficient to predict survival in EEC patients.

Central nervous system metastases from epithelial ovarian cancer.

The aim of the study was to assess the clinical features and prognosis in patients with epithelial ovarian cancer (EOC) metastasised to the central nervous system (CNS). A total of 15 patients were studied retrospectively. Clinical and pathological data and follow-up were analysed. It was found that at the diagnosis of primary EOC, the patients were 41-69 years old (56.6 ± 8.3). The interval from diagnosis of primary EOC until the relapse was 2-39 months (19.1 ± 10.5). Palliative radiotherapy was the treatment of the CNS relapse in 13 patients (86.7%). The follow-up after CNS relapse varied 0.5-15 months (4.7 ± 4.2). At the time of retrospective analysis, none of the patients were still alive. Multifocality of the CNS metastases, the presence of synchronous extracranial metastases and locations in the brain were not associated with survival. It was concluded that the development of the CNS metastases seems to be not uncommon in patients with advanced ovarian cancer. Despite oncological treatment, they are indicators of poor prognosis, and most of the patients do not survive beyond the first year of follow-up.

Bone metastases from gynaecological epithelial cancers.

The aim of this study was to investigate the clinical features and prognosis in patients with gynaecological epithelial cancers metastasised to bones. A total of 26 patients were studied retrospectively. Clinical and pathological data were analysed along with a follow-up. It was found that the interval from primary diagnosis of cancer until bony relapse varied between 0 and 163 months (31.4 ± 36.8). Bone metastases were solitary in 11 cases and multifocal in 15 cases. A total of 14 patients demonstrated only bony metastases while 12 had both bony and non-bony metastases. The time to follow-up from the diagnosis of osseous relapse varied between 1 and 43 months (10.0 ± 10.4). During follow-ups, 13 patients died and 13 patients survived. In both univariate and multivariate analyses, synchronous non-bony metastases and symptomatic treatment without oncological therapy impaired prognosis. It was concluded that even in the presence of multiple bone metastases, some patients may benefit from radiotherapy, chemotherapy or a combination of both, rather than palliative care alone, providing they do not have additional soft tissue metastases.

An extremely rare presentation of relapse in endometrioid endometrial adenocarcinoma: isolated metastases to the tibia and humerus. Case report and review of the literature.

In endometrial carcinoma patients, metastases to bones are rare and isolated metastases to extremities are extremely rare. We describe the case of a 59-year-old patient who underwent surgery followed by adjuvant radiotherapy due to endometrioid endometrial adenocarcinoma (grade 2, FIGO Stage II). After intervals of nine and 18 months respectively, she was diagnosed with metastatic tumours located in the right tibia and in the left humerus. The metastases were confirmed by biopsy. Following irradiation of metastatic lesions, the relief of symptoms was observed, and the patient remains under observation. We conclude that patients presenting a history of endometrial carcinoma with chronic pain in the extremities should be carefully evaluated, because although extremely rare, the carcinoma can metastasize to bones. Treatment of bone metastasis from endometrioid endometrial carcinoma by irradiation may increase quality of life and prolong survival.

High Spatiotemporal Resolution 4D Flow MRI of Intracranial Aneurysms at 7T in 10 Minutes.

BACKGROUND AND PURPOSE: Patients with intracranial aneurysms may benefit from 4D flow MR imaging because the derived wall shear stress is considered a useful marker for risk assessment and growth of aneurysms. However, long scan times limit the clinical implementation of 4D flow MR imaging. Therefore, this study aimed to investigate whether highly accelerated, high resolution, 4D flow MR imaging at 7T provides reliable quantitative blood flow values in intracranial arteries and aneurysms. MATERIALS AND METHODS: We used pseudospiral Cartesian undersampling with compressed sensing reconstruction to achieve high spatiotemporal resolution (0.5 mm isotropic, ∼30 ms) in a scan time of 10 minutes. We analyzed the repeatability of accelerated 4D flow scans and compared flow rates, stroke volume, and the pulsatility index with 2D flow and conventional 4D flow MR imaging in a flow phantom and 15 healthy subjects. Additionally, accelerated 4D flow MR imaging with high spatiotemporal resolution was acquired in 5 patients with aneurysms to derive wall shear stress. RESULTS: Flow-rate bias compared with 2D flow was lower for accelerated than for conventional 4D flow MR imaging (0.31 ± 0.13, P = .22, versus 0.79 ± 0.17 mL/s, P < .01). Pulsatility index bias gave similar results. Stroke volume bias showed no difference for accelerated as well as for conventional 4D flow compared to 2D flow MR imaging. Repeatability for accelerated 4D flow was similar to that of 2D flow MR imaging. Increased temporal resolution for wall shear stress measurements in 5 intracranial aneurysms did not show a consistent effect for the wall shear stress but did show an effect for the oscillatory shear index. CONCLUSIONS: Highly accelerated high spatiotemporal resolution 4D flow MR imaging at 7T in intracranial arteries and aneurysms provides repeatable and accurate quantitative flow values. Flow rate accuracy is significantly increased compared with conventional 4D flow scans.

Does fecal diversion offer any chance for spontaneous closure of the radiation-induced rectovaginal fistula?

Analysis of the clinical course of patients with postirradiation rectovaginal fistula after fecal diversion. The studied group included 17 women with postirradiation rectovaginal fistula who underwent fecal diversion as a sole mode of treatment, between January 1987 and December 2002, in our department. All patients were subjected to radiotherapy due to cancer of the uterine cervix, administered 5-107 months before the fistula appearance (mean, 22.9 months). In 3 of 17 patients (18%), spontaneous closure of fistula was observed after 5, 6, and 9 months, respectively, from fecal diversion. Closure was confirmed by endoscopy. Length of follow-up after fecal diversion ranged from 0.5 to 122 months. The actuarial probability of spontaneous closure of postradiotherapy rectovaginal fistula was 0.24 at 9 months of follow-up and then remained stable thereafter. In conclusion, colostomy alone gives hardly a chance for closure of the postradiotherapy rectovaginal fistula. Additional surgical measures are necessary.

Vaccine era measles in an adult.

Measles should be included in the differential diagnosis of patients with fever and the characteristic viral exanthem, even if a history of adequate immunization is obtained. We present the case of a 23-year-old white female who developed high fever (103 degrees F), brightly erythematous eruptions on the face, sore throat, dry cough, and myalgia 5 days after her return to the United States following a trip to Calcutta, India. The patient had extensive facial erythema from the hairline to the neck, but some areas beneath the chin were spared. Fine erythematous papules extended down the anterior neck, and white papules were seen on the buccal mucosa. The erythematous macules spread to the trunk and extremities, eventually becoming confluent and desquamating over a period of 1 week. Defervescence occurred with desquamation. Measles serology revealed the IgM antibody as positive and the IgG antibody as negative despite 2 measles, mumps, and rubella (MMR) vaccinations at ages 15 months and 7 years. Skin biopsy was consistent with viral infection.

Construction of a tissue microarray with two millimeters cores of endometrioid endometrial cancer: factors affecting the quality of the recipient block.

The tissue microarray (TMA) method currently is not used to render a primary diagnosis of cancer, but its scientific value has been proved in studies of various cancer types. TMA technology still is not used often for uterine tumors, however. We investigated the repeatability of histological diagnosis of endometrioid endometrial cancer (EEC) using conventional histology and TMA using 2 mm cores. We examined EEC tissues from 171 patients. Formalin fixed, paraffin embedded tissue donor blocks from EEC specimens were selected and examined histologically. Duplicate 2 mm tissue cores were inserted into a TMA recipient block. EEC tissues were examined as hematoxylin-eosin stained sections from the TMAs. EEC tissue was identified in the TMAs in 158 cases (92.4%) and not found in 13 cases (7.6%). On the TMA slides, both EEC positive cores were identified in 129 cases (75.4%), but only one core in 29 cases (17.0%). Among 342 biopsies of the donor blocks (each case in duplicate), EEC was found in 287 cases (83.9%) using the TMA: 124/146 (84.9%) with superficial infiltration, 153/178 (86.0%) with deep myometrial infiltration, and 10/18 (55.6%) without myometrial infiltration. We concluded that two 2 mm tissue cores from a biopsy of a donor block inserted into a TMA recipient block were sufficient to diagnose EEC in more than 90% of cases. EEC was identified in the TMAs with similar frequency with respect to superficial and deep myometrial infiltration. Cases without myometrial infiltration were identified less often.

Post-operative radiochemotherapy in patients with gastric cancer: one department's experience of 56 patients.

OBJECTIVES: Prognosis in patients with locally advanced stomach cancer undergoing surgery alone is poor. High local failure rates in gastric cancer have been reported of up to 70%. When a relapse occurs, attempts at curative treatment are generally unsuccessful. A retrospective analysis was performed in order to determine whether post-operative radiochemotherapy improves treatment results in patients with locally advanced gastric cancer. METHODS: Between November 2004 and July 2008, 56 patients with clinical Stage IB-IV cancer of the stomach underwent curative gastrectomy and adjuvant radiochemotherapy. Patients with distant metastases were excluded from the analysis. The total radiation dose was 45.0 Gy. The chemotherapy regimen comprised a 5 day cycle of 5-fluorouracil at 425 mg m(-2) and leucovorin at 20 mg m(-2). Overall survival and disease-free survival, as well as toxicity, were estimated for all patients. RESULTS: Within the study group there were 7 (13%) local recurrences, 4 (7%) distant metastases and 8 (14%) local and distant relapses. The 2 year overall survival was 48%. A total of 19 (34%) patients developed Grade 3 gastrointestinal toxicity. There were no treatment-related deaths. CONCLUSION: Post-operative radiochemotherapy is an effective and safe regimen in patients with curatively resected locally advanced gastric cancer.
