Depth Of Infiltration

Obesity is a well-known factor that leads to many diseases including endometrial cancer. The adipose tissue is a heterogeneous organ of internal secretion. Visfatin is a newly discovered protein produced by fat tissues. The purpose of this work was to evaluate serum level concentrations of visfatin in patients with endometrial cancer based on clinical progression and histopathological tumor differentiation. The diagnostic capabilities of visfatin protein in high differentiation (FIGO III and IV) from a lower (FIGO I and II) clinical stage and prognostic degree of cell differentiation (G1 versus G2, G2 versus G3) on the basis of the analysis of the area under the ROC curve are as follows: 0.87, 0.81, and 0.86. Significantly higher concentrations of visfatin have been observed in patients with invasion of the blood vessels (p=0.02) and lymph node metastases (p=0.01) in reference to the depth of infiltration of the endometrium (p=0.004), as well as the size of the tumor (p=0.003). Visfatin serum concentrations did not differ due to the invasion of the lymphatic vessels only. Visfatin seems to be a good marker of endometrial cancer progress. High visfatin serum level predicts poor prognosis in endometrial cancer patients.

This study includes 183 patients with clinical stage I endometrial cancer subjected to peritoneal cytology, total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic and para-aortic lymphadenectomy and omental biopsy during a 12-year period in a single institution. The factors analyzed were age, menopausal state, cell type, grade, mitotic activity, myometrial invasion, lymphovascular space invasion, cervical involvement, microscopic vaginal metastases, adnexal metastases, peritoneal cytology, presence of concomitant endometrial hyperplasia and lymph node status. The overall incidences of pelvic and para-aortic lymph node metastases were found to be 15.3% (28/183) and 9.3% (17/183), respectively. In five of 17 patients (29.4%) with para-aortic nodal metastases, pelvic nodes were free of tumor. The most significant prognostic factors for positive pelvic and/or para-aortic nodes were found to be the depth of myometrial invasion, grade of tumor and age.

Background. In addition to the widely known effect of vitamin D3 (vitD3) on the skeleton, its role in the regulation of the immune response was also confirmed. Aim. The assessment of biochemical and densitometric markers of calcium-phosphate metabolism in the groups of patients with relapsing-remitting multiple sclerosis (RRMS) selected due to the serum level of vitamin D3. Methods. The concentrations of biochemical markers and indices of lumbar spine bone densitometry (DXA) were determined in 82 patients divided into vitamin D3 deficiency (VitDd), insufficiency (VitDi), and normal vitamin D3 level (VitDn) subgroups. Results. The highest level of the parathyroid hormone (PTH) and the highest prevalence of hypophosphatemia and osteopenia were demonstrated in VitDd group compared to VitDi and VitDn. However, in VitDd, VitDi, and VitDn subgroups no significant differences were observed in the levels of alkaline phosphatase (ALP) and ionized calcium (Ca2+) and in DXA indices. A negative correlation was observed between the level of vitamin D3 and the Expanded Disability Status Scale (EDSS) in the whole MS group. The subgroups were significantly different with respect to the EDSS scores and the frequency of complaints related to walking according to the EQ-5D. Conclusions. It is necessary to assess calcium-phosphate metabolism and supplementation of vitamin D3 in RRMS patients. The higher the clinical stage of the disease assessed with the EDSS, the lower the level of vitamin D3 in blood serum. Subjectively reported complaints related to difficulties with walking were reflected in the EDSS in VitDd patients.

Objective: This article reports on patients with early stage prostate cancer treated with single plus one port robotic radical prostatectomy (SPORP). Materials and methods: Since January 2014, we performed SPORP in 8 patients with localized prostate cancer. Age of patients, clinical stage, operation time, intraoperative and postoperative complications, blood loss, histopathological evaluation, postoperative continence, serum level of PSA were evaluated. Results: Mean age of the 8 patients was 59.85 years. All operations were completed without conversion to standard robotic procedure or open surgery. No intra operative complications occurred. Mean operating time was 143 minutes; prostate excision 123 minutes and urethrovesical anastomosis 20 minutes. Mean blood loss was 45 ml. Preoperative Gleason scores were (3 + 4) in one patient and (3 + 3) in 7 patients. Postoperative Gleason scores were (3 + 4) in 2 patients, and (3 + 3) in 6 patients. All these 8 cases were in T1c clinical stage. Early postoperative complications were drain leakage (n = 1), atelectasis (n = 1), wound infection (n = 1) and fever (n = 1). There was no positive surgical margin. The serum level of PSA was less than 0.2 ng/ml and no other complications happened during the 4 to 12 months follow-up period. Postoperative continence and cosmetic results were excellent. Conclusions: It is relatively easy for urologists who are skilled in traditional laparoscopic and robotic surgeries to master SPORP. However long-term outcomes of this surgery need further investigations.

Adipose tissue-derived hormones known as adipokines, like leptin, have multiple bioactions. Notwithstanding the key roles of leptin in regulating energy homeostasis and metabolism, its cardiovascular functions are complex and not fully understood. This study aimed to investigate the association between serum concentrations of leptin and lipid profiles in patients with valve calcification. Seventy-two patients with valve calcification and 72 healthy individuals participated in this case-control study. The serum levels of biochemical markers and leptin were measured by the standard enzymatic methods and enzyme-linked immunosorbent assay (ELISA) technique, respectively. Significantly increased serum concentrations of FBS (P=0.001), urea (P<0.0001), creatinine (P=0.018), P (P<0.0001), LDL-C (P=0.011) and lower Ca (P=0.006), and HDL-C (P<0.0001) levels were observed in patients compared to controls. There was no significant difference in the serum level of TG and TC of patients than controls. Systolic and diastolic blood pressures were significantly increased in patients relative to controls (P<0.0001). However, a significantly diminished serum level of leptin was observed in patients than controls (P<0.0001). The correlation analysis demonstrated that the serum leptin concentration is negatively correlated with creatinine, but it is positively correlated with systolic blood pressure (P=0.0302, P=0.0362, respectively). There was no statistically significant association between serum levels of leptin and lipid profiles. Our findings indicated dyslipidemia and reduced serum leptin concentrations in patients with valve calcification, suggesting the role of lipid abnormalities and reduced leptin levels in the development and pathogenesis of valve calcification diseases.

Node Metastases

Cancer cells metastasize from primary tumors to regional lymph nodes and distant sites via the lymphatic and blood vascular systems, respectively. Our prior work has demonstrated that in primary breast tumors, cancer cells utilize a three-cell complex (known as tumor microenvironment of metastasis, or TMEM) composed of a perivascular macrophage, a tumor cell expressing high levels of the actin-regulatory protein mammalian enabled (Mena), and an endothelial cell as functional “doorways” for hematogenous dissemination. Here, we studied a well-annotated case–control cohort of human invasive ductal carcinoma of the breast and metastatic lymph nodes from a separate breast cancer cohort. We demonstrate that in primary breast tumors, blood vessels are always present within tumor cell nests (TCNs) and tumor-associated stroma (TAS), while lymphatic vessels are only occasionally present in TCN and TAS. Furthermore, TMEM doorways not only exist in primary tumors as previously reported but also in lymph node metastases. In addition, we show that TMEM intravasation doorways are restricted to the blood vascular endothelium in both primary tumors and lymph node metastases, suggesting that breast cancer dissemination to distant sites from both primary tumors and metastatic foci in lymph nodes occurs hematogenously at TMEM doorways. TMEMs are very rarely detected at lymphatic vessels and do not confer clinical prognostic significance, indicating they are not participants in TMEM-associated hematogenous dissemination. These findings are consistent with recent observations that hematogenous dissemination from lymph nodes occurs via blood vessels.

The levels of soluble interleukin-2 receptors (sIL-R2) were measured in the serum of 52 patients with epithelial ovarian carcinoma as well as in 25 age and sex-matched normal controls. The mean serum level of sIL-2R was increased in 37 patients (71.2%). Comparison of these levels to those of normal controls showed a highly statistically significant difference (p<0.001). Serum sIL-2R levels were not related to histology, clinical stage or the presence of ascites (p-0.58, p=0.32 and p=0.67, respectively), nor did they follow disease activity or response to chemotherapy. However, patients with higher pretreatment sIL-2R levels (more than 1200 U/ml) were found to have a longer survival (p<0.02), possibly explained by the presence of activated lymphocytes and a better immune surveillance. We conclude that the serum level of sIL-2R: a) is elevated in ovarian cancer patients, b) has no relationship with histological subtypes, tumor burden or the presence of ascites, c) cannot serve as a valuable tumor marker for the monitoring of patient treatment, and d) has a prognostic value for survival.
