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.

Objective: There is no research regarding the appropriate antiemetic agents for female patients, especially those receiving moderately emetogenic chemotherapy (MEC). We evaluated the antiemetic efficacy of a combination of 5-HT3 receptor with/ without aprepitant in patients with gynecological cancer treated with the TC (paclitaxel and carboplatin) regimen of MEC. Methods: We enrolled 38 patients diagnosed with gynecologic cancer and scheduled to receive the TC regimen. The patients were randomly assigned to receive a 5-HT3 receptor antagonist, either palonosetron in the first cycle followed by granisetron in the second cycle or vice versa. In the third cycle, all patients received a combination of the 5-HT3 receptor and dexamethasone with/without aprepitant. Results: When three drugs were administered, palonosetron consistently produced an equivalent complete response (CR) rate to granisetron in the acute phase (89.5% vs. 86.8%, p=0.87) and delayed phase (60.5% vs. 65.8%, p=0.79). With regard to the change in dietary intake, palonosetron exhibited similar efficacy to granisetron in the acute phase (92.1% vs. 89.4%, p=0.19) and delayed phase (65.7% vs. 68.4%, p=0.14). However, in the delayed phase, the addition of aprepitant therapy with a 5-HT3 receptor antagonist and dexamethasone produced a higher CR rate than a 5-HT3 receptor antagonist with dexamethasone (93.3% vs. 47.8%, p<0.001) and allowed the patients to maintain a higher level of dietary intake (93.3% vs. 56.5%, p<0.001). Conclusion: The addition of aprepitant therapy was more effective than the control therapy of a 5-HT3 receptor antagonist, and dexamethasone in gynecological cancer patients treated with the TC regimen.
