ObjectiveTo establish new criteria for the omission of lymphadenectomy in patients with endometrioid carcinoma.Methods We retrospectively reviewed 185 cases of histologically confirmed endometrioid carcinoma by hysterectomy at Jichi Medical University Hospital between January 2006 and December 2011. We reviewed patient medical records to detect risk factors for lymph node metastasis to identify the optimum criteria for lymphadenectomy omission.ResultsUnivariate analysis revealed risk factors for lymph node metastasis to be a large tumor size (volume index ≥40 cm³) (p<0.0001), tumor diameter >2 cm (p=0.0003), myometrial invasion ≥50% based on pre-operative MRI (p=0.0366), elevated serum CA125 (pre-menopausal value ≥70 U/mL, post-menopausal value ≥25 U/mL) (p=0.0004), and lymphadenopathy on pre-operative CT scans (p=0.0002). Multivariate analysis indicated that tumor volume index, tumor diameter, elevated serum CA125, and CT scans positive for lymphadenopathy were independent risk factors for lymph node metastasis. Thus, we set tumor diameter >2 cm, elevated serum CA125, and CT scans positive for lymphadenopathy as risk factors. In cases with no risk factors, the rate of lymph node metastasis was 2.1%, which rose to 8.9%, 30.4%, and 58.3% for those with one, two, and three risk factors, respectively. The rate of para-aortic lymph node metastasis rose from 0% to 2.5%, 10.9%, and 41.7% among those with zero, one, two, and three risk factors, respectively.ConclusionsWe propose that lymphadenectomy can be omitted in cases of endometrioid carcinoma that do not have any of the following risk factors: tumor diameter >2 cm, elevated serum CA125, and a CT scan positive for lymphadenopathy. We believe that these new criteria will limit inter-institutional differences as they are all objective factors. Further, they are useful in predicting lymph node metastasis, including para-aortic lymph node metastasis, based on the number of risk factors present.
Dietary fiber content of foodstuffs commonly used for diabetics was determined by the sum of neutral detergent fiber plus pectin. The increasing interest in dietary fiber and its relation to human health and disease has created a great need for dietary fiber content of foods. Neutral detergent fiber values were given as the residues after Van Soest neutral detergent fiber treatment. Pectin values were determined by Ca-Pactate method.
Key Clinical Message Pregnancy complicated by ankylosing spondylitis is rare. Labor assistance and instrumental delivery may be difficult due to hip stiffness. Restriction in lumbar flexion may cause difficulties in administering neuraxial analgesia. Difficult intubation for general anesthesia due to limited neck mobility is another potential risk that must be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
