Objective: Our objective was to determine the feasibility and detection rates and clarify the most effective combination of injected tracer types for sentinel lymph node (SLN) mapping in uterine cervical cancer in patients who have undergone laparoscopic surgery or neoadjuvant chemotherapy (NAC). Methods: A total of 119 patients with cervical cancer underwent SLN biopsy at radical hysterectomy using three types of tracers. The various factors related to side-specific detection rate, sensitivity, and false negative (FN) rate were analyzed. Results: The SLN detection rates using 99m-technetium (99mTc)-tin colloid, indigo carmine, and indocyanine green (ICG) were 85.8%, 20.2%, and 61.6%, respectively. The patients with ≥2-cm-diameter tumors and those who received NAC had lower detection rates than those with <2-cm-diameter tumors (75.7% vs. 91.5%, p<0.01) and those who did not receive NAC (67.9% vs. 86.3%, p<0.01), respectively. Laparoscopic procedures had a higher detection rate than laparotomy (100.0% vs. 77.1%, p<0.01). No factors significantly affected the sensitivity; however, the patients with ≥2-cm-diameter tumors (86.0% vs. 1.4%, p<0.01), NAC (19.4% vs. 2.2%, p<0.01), and those who underwent laparotomy (7.4% vs. 0%, p<0.01) had an unfavorable FN rate. Conclusion: Among the examined tracers, 99mTc had the highest detection of SLN mapping in patients with uterine cervical cancer. Patients with local advanced cervical cancer with/without NAC treatment might be unsuited for SLN mapping. SLN mapping is feasible and results in an excellent detection rate in patients with <2-cm-diameter cervical cancer. Laparoscopic surgery is the best procedure for SLN detection in patients with early-stage disease.

Human-like Patient Robot with Chaotic Emotion for Injection Training
Yoshiro Kitagawa,Tomohito Ishikura,Wei Song,Yasushi Mae,Mamoru Minami,Kanji Tanaka 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
In this paper, we present a system of patient robot developed with the aim at improving abilities of nursing student’s medical treatment, such as injection to vein. We propose to realize variable emotion of patient robot by using chaosorbit of non-linear time-differentiation equation. To evaluate the effectiveness of the robot through actual injec-tion training, we measure heart beat rate of nurse student during the injection training, proving the effects of the robot’s similarity to human. To make the patient robot to be self-contained for the training, we propose a 3-D injector pose recognition method of patient robot to help that the robot be have autonomously along with the injection procedures of the nurse studens trainings.
