ObjectiveTo detect level of circulating tumor cells (CTCs) in peripheral venous blood of fasting patients with gastric cancer (GC) and to analyze relationships between CTCs and clinicopathologic features and prognosis of patients with GC.MethodsOne hundred patients with GC were selected (GC group), who underwent the surgery and confirmed by the histopathology in the 940 Hospital of Joint Service of PLA, from August 2015 to December 2016. Thirty-eight patients with gastric benign lesions who were treated in this hospital at the same time were selected as the control group. The 7 mL peripheral venous blood of the elbow in the morning was taken from the fasting patients and the CTCs were detected by the immunomagnetic microparticle negative enrichment combined with immunofluorescence in situ hybridization within 24 h. The positive rate of CTCs was calculated and its relationships with the clinicopathologic features (tumor location, tumor invasion depth, degree of differentiation, TNM stage, lymph node metastasis, and vascular tumor thrombus) and the progression-free survival of the patients with GC were analyzed.ResultsThe positive rate of peripheral venous blood CTCs in the GC group was 89.0% (89/100), which was higher than that in the control group (10.5%, 4/38), and the difference was statistically significant (P<0.001). The levels of CTCs in the patients with GC were significantly correlated with the tumor invasion depth (P=0.017), lymph node metastasis (P=0.038), and TNM stage (P=0.016), which were not associated with the age, gender, tumor location, degree of differentiation, and vascular tumor thrombus (P>0.050). The predictive value of CTCs for the diagnosis of GC was significantly superior to that of the tumor markers CEA, CA19-9, or CA125. The progression-free survival of patients with low CTCs expression was significantly longer than that in the patients with high CTCs expression (χ2=5.172, P=0.023).ConclusionsDetecting CTCs of patients with GC by immunomagnetic particle negative enrichment combined with immunofluorescence in situ hybridization has a high sensitivity. And it can improve early diagnosis of patients with GC. Preoperative CTCs detection has a certain value in guiding staging of GC and predicting prognosis of patients with GC.
Objective To explore the feasibility and safety of tension-free vaginal tape-obturator for female stress urinary incontinence under the daytime surgical mode based on the concept of enhanced recovery after surgery. Methods The clinical data of female patients with stress urinary incontinence at the First Affiliated Hospital of Kunming Medical University between June 2019 and June 2023 were retrospectively analyzed. According to the perioperative management mode of patients, they were divided into daytime surgery group and routine surgery group. The basic, intraoperative, and postoperative conditions of two groups of patients were compared. Results Finally, 183 patients were included, including 91 in the routine surgery group and 92 in the daytime surgery group. All patients successfully completed the surgery. There was no statistically significant difference in age, preoperative comorbidities, surgeon in chief, or operation duration between the two groups of patients (P>0.05). The preoperative waiting time after hospitalization [(0.00±0.00) vs. (2.42±0.58) d], hospitalization expenses [(13815.10±2906.01) vs. (18095.21±3586.67) yuan], total surgical expenses [(3961.36±707.35) vs. (4440.19±1016.31) yuan], anesthesia expenses [(718.53±61.06) vs. (755.30±74.65) yuan], western medicine expenses [(818.07±259.30) vs. (1282.14±460.75) yuan], total hospitalization duration [(1.11±0.31) vs. (5.77±1.30) d], and postoperative hospitalization duration [(1.11±0.31) vs. (3.35±1.42) d] in the daytime surgery group were lower than those in the routine surgery group (P<0.05). There was no significant difference between the two groups in postoperative complications (respiratory complications, fever, nausea and vomiting, vaginal bleeding, urinary retention, peritonitis), satisfaction, postoperative pain or self perception of symptom improvement (P>0.05). Conclusion The daytime surgery for female stress urinary incontinence based on the concept of enhanced recovery after surgery is safe and feasible, which can shorten hospitalization duration and reduce hospitalization costs.
