Lymphovascular space invasion and cervical stromal invasion are independent risk factors for nodal metastasis in endometrioid endometrial cancer

Abstract: Aims The purpose of this study was to investigate the potential roles of pathological variables in the prediction of nodal metastasis in women with endometrioid endometrial cancer (EC). Materials and Methods Women who underwent surgery for endometrioid EC between 1995 and 2012 were retrospectively reviewed. Those who underwent prior neoadjuvant chemotherapy or radiotherapy and inadequate lymphadenectomy as well as those with nonendometrioid histology, synchronous cancers, International Federation of Gynecology and Obstetrics stage IV disease, gross uterine serosal and/or gross adnexal involvement were excluded. Lymph node dissemination was defined as occurring in the following circumstances: (i) when nodal metastasis with pelvic and/or para-aortic (P/PA) lymph node dissection (LND) was performed or (ii) when there was recurrence in the P/PA lymph nodes after a negative LND or when LND was not performed. Univariate and multivariate logistic regression models were used to identify the pathological predictors of lymphatic dissemination. Results A total of 827 women with endometrioid EC were assessed; 516 (62.4%) of whom underwent P/PA LND and 205 (24.8%) underwent P LND. Sixty-seven (13%) women in the P/PA LND group and 5 (2.4%) in the P LND group had positive lymph nodes. Multivariate analysis confirmed cervical stromal invasion (OR 4.04, 95% CI 2.02–8.07 (P < 0.001)) and lymphovascular space invasion (LVSI) (OR 110.18, 95% CI 38.43–315.87 (P < 0.001)) as independent predictors of lymphatic dissemination. Conclusion Cervical stromal invasion and LVSI are highly associated with LN metastasis. These markers may serve as a surrogate for nodal metastasis.

The influence of religious fasting on basal tear secretion and tear break-up time

Abstract: Muslims abstain from food and drink from dawn to sunset during the holy month of Ramadan. An extended strict fasting may influence tear secretion and quality. We investigated changes in basal tear secretion (BTS) and tear break-up time (BUT) at the beginning and at the end of fasting on 32 healthy male patients with a mean age of 22.3 ± 2.9 years. Body weight and urine specific gravity were also determined to assess the extent of dehydration due to fasting. Each case lost 0.1–1.25 kg of body weight while urine specific gravity changes were statistically insignificant. Mean BTS amount was 19.9 ± 10.9 mm at the initial examination and 19.7 ± 11.5 mm at the end of fasting (p=0.9). BUT values were 20.1 ± 9.3 sec at the beginning of fasting and 23.5 ± 14.9 sec at the end of fasting (p=0.19). We found that religious fasting in the winter season does not seem to affect BTS and BUT values in healthy individuals.
