Objective: While cytology-based screening programs have significantly reduced mortality and morbidity from cervical cancer, the global consensus is that primary human papillomavirus (HPV) testing increases detection of high-grade cervical intraepithelial neoplasia (CIN) and invasive cancer. However, the optimal triage strategy for HPV+ women to avoid over-referral to colposcopy may be setting specific. We compared absolute and relative risk (RR) of >CIN2/3 within 12 months of a negative cytologic result in women HPV16/18+ compared to those with a 12-other high-risk HPV (hrHPV) genotype to identify women at greatest risk of high-grade disease and permit less aggressive management of women with other hrHPV infections. Methods: Participants were 14,160 women aged 25–69 years with negative cytology participating in the COMparison of HPV genotyping And Cytology Triage (COMPACT) study. Women who were HPV16/18+ were referred to colposcopy. Those with a 12-other hrHPV type underwent repeat cytology after 6 months and those with >abnormal squamous cells of undetermined significance went to colposcopy. Results: Absolute risk of >CIN2 in HPV16/18+ women was 19.5% (95% CI=12.4%–29.4%). In women 25–29 years and HPV16+ it was 40.0% (95% CI=11.8%–76.9%). Absolute risk of >CIN3 in women HPV16/18+ was 11.0% (95% CI=5.9%–19.6%). For women 30–39 years and HPV16+ it was 23.1% (95% CI=5.0%–53.8%). Overall risk of >CIN2, >CIN3 in women with a 12-other hrHPV HPV type was 5.6% (95% CI=3.1%–10.0%) and 3.4% (95% CI=1.6%–7.2%) respectively. RR of >CIN2, >CIN3 in HPV16/18+ vs. 12-other hrHPV was 3.5 (95% CI=1.7–7.3) and 3.3 (95% CI=1.2–8.8), respectively. Conclusion Primary HPV screening with HPV16/18 partial genotyping is a promising strategy to identify women at current/future risk of >CIN2 in Japan without over-referral to colposcopy.

Precision cancer surgery is a system that integrates the accurate evaluation of tumor extension and aggressiveness, precise surgical maneuvers, prognosis evaluation, and prevention of the deterioration of quality of life (QoL). In this regard, nerve-sparing radical hysterectomy has a pivotal role in the personalized treatment of cervical cancer. Various types of radical hysterectomy can be combined with the nerve-sparing procedure. The extent of parametrium and vagina/paracolpium excision and the nerve-sparing procedure are tailored to the tumor status. Advanced magnetic resonance imaging technology will improve the assessment of the local tumor extension. Validated risk factors for perineural invasion might guide selecting treatment for cervical cancer. Type IV Kobayashi (modified Okabayashi) radical hysterectomy combined with the systematic nerve-sparing procedure aims to both maximize the therapeutic effect and minimize the QoL impairment. Regarding the technical aspect, the preservation of vesical nerve fibers is essential. Selective transection of uterine nerve fibers conserves the vesical nerve fibers as an essential piece of the pelvic nervous system comprising the hypogastric nerve, pelvic splanchnic nerves, and inferior hypogastric plexus. This method is anatomically and surgically valid for adequate removal of the parametrial and vagina/paracolpium tissues while preserving the total pelvic nervous system. Local recurrence after nerve-sparing surgery might occur due to perineural invasion or inadequate separation of pelvic nerves cutting through the wrong tissue plane between the pelvic nerves and parametrium/paracolpium. Postoperative management for long-term maintenance of bladder function is as critical as preserving the pelvic nerves.

OBJECTIVE: Rikkunshito, an herbal medicine, is widely prescribed in Japan for the treatment of anorexia and functional dyspepsia, and has been reported to recover reductions in food intake caused by cisplatin. We investigated whether rikkunshito could improve chemotherapy-induced nausea and vomiting (CINV) and anorexia in patients treated with cisplatin. METHODS: Patients with uterine cervical or corpus cancer who were to receive cisplatin (50 mg/m² day 1) and paclitaxel (135 mg/m² day 0) as first-line chemotherapy were randomly assigned to the rikkunshito group receiving oral administration on days 0–13 with standard antiemetics, or the control group receiving antiemetics only. The primary endpoint was the rate of complete control (CC: no emesis, no rescue medication, and no significant nausea) in the overall phase (0–120 hours). Two-tailed p<0.20 was considered significant in the planned analysis. RESULTS: The CC rate in the overall phase was significantly higher in the rikkunshito group than in the control group (57.9% vs. 35.3%, p=0.175), as were the secondary endpoints: the CC rate in the delayed phase (24–120 hours), and the complete response (CR) rates (no emesis and no rescue medication) in the overall and delayed phases (63.2% vs. 35.3%, p=0.095; 84.2% vs. 52.9%, p=0.042; 84.2% vs. 52.9%, p=0.042, respectively), and time to treatment failure (p=0.059). Appetite assessed by visual analogue scale (VAS) appeared to be superior in the rikkunshito group from day 2 through day 6. CONCLUSION: Rikkunshito provided additive effect for the prevention of CINV and anorexia.

OBJECTIVE: The aim of this study was to clarify the clinical significance of isolated tumor cells (ITCs) or micrometastasis (MM) in regional lymph nodes in patients with International Federation of Gynecology and Obstetrics (FIGO) stage I to II endometrial cancer. METHODS: In this study, a series of 63 patients with FIGO stage I to II were included, who had at least one of the following risk factors for recurrence: G3 endometrioid/serous/clear cell adenocarcinomas, deep myometrial invasion, cervical involvement, lympho-vascular space invasion, and positive peritoneal cytology. These cases were classified as intermediate-risk endometrial cancer. Ultrastaging by multiple slicing, staining with hematoxylin and eosin and cytokeratin, and microscopic examination was performed on regional lymph nodes that had been diagnosed as negative for metastases. RESULTS: Among 61 patients in whom paraffin-embedded block was available, ITC/MM was identified in nine patients (14.8%). Deep myometrial invasion was significantly associated with ITC/MM (p=0.028). ITC/MM was an independent risk factor for extrapelvic recurrence (hazard ratio, 17.9; 95% confidence interval [CI], 1.4 to 232.2). The 8-year overall survival (OS) and recurrence-free survival (RFS) rates were more than 20% lower in the ITC/MM group than in the node-negative group (OS, 71.4% vs. 91.9%; RFS, 55.6% vs. 84.0%), which were statistically not significant (OS, p=0.074; RFS, p=0.066). Time to recurrence tended to be longer in the ITC/MM group than in the node-negative group (median, 49 months vs. 16.5 months; p=0.080). CONCLUSIONS: It remains unclear whether ITC/MM have an adverse influence on prognosis of intermediate-risk endometrial cancer. A multicenter cooperative study is needed to clarify the clinical significance of ITC/MM.

OBJECTIVE: According to the International Federation of Gynecology and Obstetrics staging, some surgeons perform lymphadenectomy in all patients with early stage endometrial cancer to enable the accurate staging. However, there are some risks to lymphadenectomy such as lower limb lymphedema. The aim of this study was to investigate whether preoperative assessment is useful to select the patients in whom lymphadenectomy can be safely omitted. METHODS: We evaluated the risk of lymph node metastasis (LNM) using LNM score (histological grade, tumor volume measured in magnetic resonance imaging [MRI], and serum CA-125), myometrial invasion and extrautrerine spread assessed by MRI. Fifty-six patients of which LNM score was 0 and myometrial invasion was less than 50% were consecutively enrolled in the study in which a lymphadenectomy was initially intended not to perform. We analyzed several histological findings and investigated the recurrence rate and overall survival. RESULTS: Fifty-one patients underwent surgery without lymphadenectomy. Five (8.9%) who had obvious myometrial invasion intraoperatively underwent systematic lymphadenectomy. One (1.8%) with endometrial cancer which was considered to arise from adenomyosis had para-aortic LNM. Negative predictive value of deep myometrial invasion was 96.4% (54/56). During the mean follow-up period of 55 months, one patient with deep myometrial invasion who refused an adjuvant therapy had tumor recurrence. The overall survival rate was 100% during the study period. CONCLUSION: This preoperative assessment is useful to select the early stage endometrial cancer patients without risk of LNM and to safely omit lymphadenectomy.

OBJECTIVE: The aim of this study was to investigate the prognostic factors and treatment outcome of patients with adenocarcinoma of the uterine cervix who underwent radical hysterectomy with systematic lymphadenectomy. METHODS: A total of 130 patients with stage IB to IIB cervical adenocarcinoma treated with hysterectomy and systematic lymphadenectomy from 1982 to 2005 were retrospectively analyzed. Clinicopathological data including age, stage, tumor size, the number of positive node sites, lymphovascular space invasion, parametrial invasion, deep stromal invasion (>2/3 thickness), corpus invasion, vaginal infiltration, and ovarian metastasis, adjuvant therapy, and survival were collected and Cox regression analysis was used to determine independent prognostic factors. RESULTS: An estimated five-year survival rate of stage IB1 was 96.6%, 75.0% in stage IB2, 100% in stage IIA, and 52.8% in stage IIB. Prognosis of patients with one positive-node site is similar to that of those with negative-node. Prognosis of patients with multiple positive-node sites was significantly poorer than that of negative and one positive-node site. Multivariate analysis revealed that lymph node metastasis, lymphovascular space invasion, and parametrial invasion were independent prognostic factors for cervical adenocarcinoma. Survival of patients with cervical adenocarcinoma was stratified into three groups by the combination of three independent prognostic factors. CONCLUSION: Lymph node metastasis, lymphovascular space invasion, and parametrial invasion were shown to be independent prognostic factors for cervical adenocarcinoma treated with hysterectomy and systematic lymphadenectomy.

OBJECTIVE: Few studies on the prognosticators of the patients with recurrent endometrial cancer after relapse have been reported in the literature. The aim of this study was to determine the prognosticators after relapse in patients with recurrent endometrial cancer who underwent primary complete cytoreductive surgery and adjuvant chemotherapy. METHODS: Thirty-five patients with recurrent endometrial cancer were included in this retrospective analysis. The prognostic significance of several clinicopathological factors including histologic type, risk for recurrence, time to relapse after primary surgery, number of relapse sites, site of relapse, treatment modality, and complete resection of recurrent tumors were evaluated. Survival analyses were performed by Kaplan-Meier curves and the log-rank test. Independent prognostic factors were determined by multivariate Cox regression analysis. RESULTS: Among the clinicopathological factors analyzed, histologic type (p=0.04), time to relapse after primary surgery (p=0.03), and the number of relapse sites (p=0.03) were significantly related to survival after relapse. Multivariate analysis revealed that time to relapse after primary surgery (hazard ratio, 6.8; p=0.004) and the number of relapse sites (hazard ratio, 11.1; p=0.002) were independent prognostic factors for survival after relapse. Survival after relapse could be stratified into three groups by the combination of two independent prognostic factors. CONCLUSION: We conclude that time to relapse after primary surgery, and the number of relapse sites were independent prognostic factors for survival after relapse in patients with recurrent endometrial cancer.
