This is the first study
to evaluate the activity of the serum senescence marker GAL in colon cancer patients with a history of alcohol and nicotine dependence, as a potential factor of worse cancer prognosis.
Material and Methods: The material was serum of 18 colon cancer patients and 10 healthy volunteers. Ten colon cancer patients met alcohol and nicotine XMU-MP-1 mw dependence criteria. The activity of beta-galactosidase (pkat/ml) was determined by the colorimetric method. Comparisons between groups were made using the Kruskal-Wallis analysis and differences evaluated using the Mann-Whitney U test. Spearman’s rank correlation coefficient was used to measure the statistical dependence between two variables.
Results: The activity of serum GAL was significantly higher in colon cancer patients with a history of alcohol and nicotine dependence, in comparison to colon cancer patients without a history of drinking/smoking (p=0.015; 46% increase), and the controls (p=0.0002; 81% increase). The activity of serum GAL in colon cancer patients without a history of alcohol/nicotine dependence was higher
than the activity in the controls (p=0.043; 24% increase).
Discussion/Conclusion: 5-Fluoracil in vitro Higher activity of beta-galactosidase may potentially reflect the accelerated growth of the cancer, invasion, metastases, and maturation, when alcohol and nicotine dependence coincide with colon cancer. For a better prognosis of colon cancer, alcohol and nicotine withdrawal seems to be required.”
“OBJECTIVE: To estimate the risk for nodal metastasis in women with endometrial cancer based on uterine
characteristics on pathology.
METHODS: From a study of staging for uterine cancer, women were identified as being at low risk for nodal metastasis based on three specific criteria on final pathology reports: 1) less than 50% invasion, 2) tumor size less than 2 cm, and 3) well or moderately differentiated endometrioid histology. If the uterine specimen did not meet all three criteria, it was viewed as high risk for nodal metastasis.
RESULTS: Nine hundred seventy-one women were included in this analysis. Approximately 40% (or 389 of 971) of patients in this study were found to be at low risk, with a rate of nodal metastasis of only 0.8% (3 of 389; exact 95% confidence interval [CI] 0.16-2.2). No statistical differences in median Neuronal Signaling inhibitor age, body mass index, race, performance status, missing clinical data, or open or minimally invasive techniques were found among the patients with and without nodal metastases. Patients with high-risk characteristics of their uterine specimens compared with those with low-risk characteristics have 6.3 times the risk of nodal metastasis (95% CI 1.67-23.8, P=.007).
CONCLUSION: Low-risk endometrioid uterine cancer criteria may be used to help guide treatment planning for reoperation in patients with incomplete surgical staging information. (Obstet Gynecol 2072;119:286-92) DOI: 10.
