Prognostic Significance of Retroperitoneal Lymphadenectomy, Preoperative Neutrophil Lymphocyte Ratio and Platelet Lymphocyte Ratio in Primary Fallopian Tube Carcinoma: A Multicenter Study / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The purpose of this study is to evaluate the prognostic role of preoperative neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) and the need for para-aortic lymphadectomy in patients with primary fallopian tube carcinoma (PFTC). MATERIALS AND METHODS: Ninety-one patients with a diagnosis of PFTC were identified through the gynecologic oncology service database of six academic centers. Clinicopathological, surgical, and complete blood count data were collected. RESULTS: In univariate analysis, advanced stage, suboptimal surgery, and NLR > 2.7 were significant prognostic factors for progression-free survival, whereas in multivariate analysis, only advanced stage and suboptimal surgery were significant. In addition, in univariate analysis, cancer antigen 125 > or = 35 U/mL, ascites, advanced stage, suboptimal surgery, NLR > 2.7, PLR > 233.3, platelet count > or =400,000 cells/mm3, staging type, and histological subtype were significant prognostic factors for overall survival (OS); however, in multivariate analysis, only advanced stage, suboptimal surgery, NLR > 2.7, and staging type were significant. Inclusion of pelvic and para-aortic lymphadenectomy in surgery showed significant association with longer OS, with a mean and median OS of 42.0 months and 35.5 months (range, 22 to 78 months), respectively, vs. 33.5 months and 27.5 months (range, 14 to 76 months), respectively, for patients who underwent surgery without para-aortic lymphadenectomy (hazard ratio, 3.1; 95% confidence interval, 1.4 to 5.7; p=0.002). CONCLUSION: NLR (in both univariate and multivariate analysis) and PLR (only in univariate analysis) were prognostic factors in PFTC. NLR and PLR are inexpensive and easy tests to perform. In addition, patients with PFTC who underwent bilateral pelvic and para-aortic lymphadenectomy had longer OS.

Granulocyte-colony stimulating factor decreases the extent of ovarian damage caused by cisplatin in an experimental rat model / 부인종양

OBJECTIVE: To investigate whether granulocyte-colony stimulating factor (G-CSF) can decrease the extent of ovarian follicle loss caused by cisplatin treatment. METHODS: Twenty-one adult female Sprague-Dawley rats were used. Fourteen rats were administered 2 mg/kg/day cisplatin by intraperitoneal injection twice per week for five weeks (total of 20 mg/kg). Half of the rats (n=7) were treated with 1 mL/kg/day physiological saline, and the other half (n=7) were treated with 100 microg/kg/day G-CSF. The remaining rats (n=7, control group) received no therapy. The animals were then euthanized, and both ovaries were obtained from all animals, fixed in 10% formalin, and stored at 4degrees C for paraffin sectioning. Blood samples were collected by cardiac puncture and stored at -30degrees C for hormone assays. RESULTS: All follicle counts (primordial, primary, secondary, and tertiary) and serum anti-Mullerian hormone levels were significantly increased in the cisplatin+G-CSF group compared to the cisplatin+physiological saline group. CONCLUSION: G-CSF was beneficial in decreasing the severity of follicle loss in an experimental rat model of cisplatin chemotherapy.

Thrombopoietin: a novel candidate tumor marker for the diagnosis of ovarian cancer / 부인종양

OBJECTIVE: To investigate the decisive role of preoperative serum thrombopoietin levels in the discrimination of benign and malignant ovarian pathologies and its value in the evaluation of treatment response. METHODS: Fifty patients with diagnoses of adnexal masses (25 benign, 25 malignant) were included in the study. Blood samples were collected from all cases preoperatively. Age, menopausal status, adnexal mass size, preoperative CA-125 level, platelet count, the stage of the disease (FIGO stage), tumor grade, histologic subgroup, the residual tumor mass, ascites cytology, surgical procedures, and postoperative treatments were recorded for the malignant group. Response to treatment was evaluated based on the revised RECIST guideline. RESULTS: The preoperative serum thrombopoietin levels of the malignant cases (median, 98; range, 7 to 768) were significantly higher when compared with those of benign cases (median, 27; range, 13 to 131; p=0.004). The positive predictive value of CA-125 was found to be 79%, when it was used as a single marker; however it had risen to 85% when both CA-125 and thrombopoietin levels were used. There was no significant relationship between preoperative serum thrombopoietin levels and tumor grade, ascites cytology, presence of residual mass, and response to treatment. The preoperative serum thrombopoietin levels were significantly higher in stage III-IV cases and cases with serous histology. The post-treatment serum thrombopoietin levels in the malignant group were significantly lower as compared with the preoperative thrombopoietin levels. CONCLUSION: Thrombopoietin can play an additive role for prediction of ovarian cancer.

effects of raloxifene treatment on oxidative status in brain tissues and learning process of ovariectomized rats

The effects of estrogene on central nervous system are still controversial. We aimed to investigate the effects of raloxifene on the antioxidant enzyme [superoxide dismutase [SOD] and catalase [CAT]] activities and malondialdehyde [MDA] levels in brain homogenates of ovariectomized female rats and its effect on cognitive process of learning. Female Sprague Dawley rats [n=24] were divided into three groups. Three weeks after ovariectomy; nonovariectomized group [control group] [n=8] was given physiological saline [SP] as placebo. First ovariectomized group [n=8] received raloxifene 1mg/kg dissolved in a 1% solution of carboxymethylcellulose [CMC] subcutaneusly [sc] and second group of ovariectomized rats were given 1% CMC 1mg/kg [sc] every day for 14 days. Learning behaviors of rats were evaluated in active avoidence cage with using sound and electrical stimulation. The levels of oxidative stress [MDA] and antioxidant enzymes [SOD, CAT] in different regions of the brain homogenates were compared between three groups of decapitated rats. Raloxifene had a significant attenuating effect on the levels of MDA in brain tissues suggesting raloxifene's effect against lipid peroxidation at the end of training days. With the comparison of brain regions, cortex showed the highest average activity of SOD and CAT and cerebellum had the lowest average levels for both. Its effects on learning and cognitive process with active avoidence task were considered insignificant. Raloxifene treatment may have preventive effects for the brain against oxidative stress and lipid peroxidation in rats

Different types of variable decelerations and their effects to neonatal outcome

<p><b>OBJECTIVE</b>Although the only objective finding of intrapartum fetal distress is obtained through the measurement the fetal scalp pH, this invasive procedure is not available in every institution. The careful examination of fetal heart rate tracings for abnormalities, especially of the most commonly seen one, variable decelerations gains great importance under these circumstances. The aim of the present study is to determine the prognostic significance of variable decelerations in intrapartum fetal heart rate monitoring.</p><p><b>METHODS</b>A total of 96 fetal heart rate tracings were analysed to assess the prognostic significance of variable decelerations. Sixty-six percent (64/96) of cases exhibited atypia characterised with (1) slow return of the fetal heart rate to the baseline; (2) loss of variability during the decelerations; (3) loss of initial and/or secondary accelerations; (4) persistence of secondary acceleration (overshoot); and (5) continuation of the baseline fetal heart rate at a lower level; (6) biphasic deceleration. One and five-minute Apgar scores and umbilical artery pH were used to assess the final fetal condition.</p><p><b>RESULTS</b>Adverse fetal outcome characterised by fetal acidosis and Apgar score lower than 7 at one and five minutes were uncommon with pure variable decelerations. Typical and atypical variable decelerations were associated with low Apgar scores (< 7) at one minute in 9.3% and 54.6% of cases (p < 0.001) and at five minutes in 6.25% and 25% of cases (p < 0.05), respectively. In addition umbilical artery pH found to be lower than 7.2 in these cases ( 18.75% - p < 0.05). There was no danger for the fetal haemodynamic conditions when typical uterus contraction/variable deceleration ratios were two or more than two. However, risk of fetal hypoxia damage was quite high when this ratio was lower than two in atypical variable 5th minute low Apgar scores and pH (81.8% and 36.6% respectively). Atypical features are helpful in the identification of distress characterised by low Apgar scores in fetuses with variable decelerations. Admission to the neonatal intensive care unit was more common in patients with atypical variable decelerations in comparison with typical variable decelerations (34.3% versus 3.1%).</p><p><b>CONCLUSION</b>While typical variable decelerations are frequently harmless, atypical variations pose a significant risk of fetal hypoxia.</p>
