AMIGO2 expression as a predictor of recurrence in cervical cancer with intermediate risk.

Patients with recurrent cervical cancer have limited treatment options and are often considered to be incurable. Since the expression of amphoterin-induced gene and open reading frame 2 (AMIGO2) in clinical samples is a prognostic factor for colorectal cancer and gastric cancer, the present aimed to elucidate whether it is also a prognostic factor for cervical cancer. Patients with primary cervical cancer who underwent radical hysterectomy or radical trachelectomy at our institution (Faculty of Medicine, Tottori University, Yonago, Japan) between September 2005 and October 2016 were retrospectively collected. Immunohistochemical analysis using a specific antibody against AMIGO2 was performed on 101 tumor samples, and the clinical characteristics, disease-free survival (DFS) and overall survival (OS) of the patients were examined. Patients in the AMIGO2-high group had a shorter 5-year DFS and OS than those in the AMIGO2-low group (P<0.001). Furthermore, AMIGO2 was an independent prognostic factor for DFS in multivariate analysis (P=0.0012). Patients in the AMIGO2-high group exhibited obvious recurrence compared with those in the AMIGO2-low group in the high-(P=0.03) and intermediate-risk groups (P=0.003). Positive lymph node metastasis, and parametrial, stromal and lymph vascular space invasion were significantly more common in AMIGO2-high patients. Taken together, AMIGO2 expression may be a predictive marker of recurrence for cervical cancer. In particular, it may be an indicator to determine the need for postoperative adjuvant therapy in intermediate-risk group patients.

"Welcome to OBGYN World!" A novel recruitment event for medical students organized by the Japan Society of Obstetrics and Gynecology.

"Welcome to OBGYN World!" A novel recruitment event for medical students organized by the Japan Society of Obstetrics and Gynecology. Since 2012, the number of doctors in Japan who specialize in obstetrics and gynecology has shown a decreasing trend. To increase the number of doctors majoring in obstetrics and gynecology, the Japanese Trainees in Obstetrics and Gynecology subcommittee developed a new recruitment event called Welcome to OBGYN World! (WOW!); the aim of this event was to focus on lower grades of medical students. The present report describes the content of WOW! and the results of a post-event questionnaire administered to participating students and tutors. WOW! was held online in order to avoid the risk of Coronavirus Disease 2019 infection for participants. Sixty of the 82 medical schools nationwide (73.2%) participated in this event. Overall, there were 285 participating students, ranging from first to fourth grade in medical school, and 106 tutors were involved to teach material at the event. In the post-event questionnaire survey, 97.6% (248/254) and 100% of the participants stated they now had a high degree of interest in obstetrics and gynecology and found the specialty attractive, respectively. Furthermore, 93.6% (90/94) of the tutors stated that WOW! had helped recruitment activities in their universities. Based on this outcome, members of the Japanese Trainees of Obstetrics and Gynecology subcommittee will now try to increase the number of doctors specializing in obstetrics and gynecology by holding WOW! annually.

Association of online activities with obstetrics and gynecology specialty choice: a nationwide online survey.

Objectives: To investigate the association between online activities and the number of new obstetrics and gynecology senior residents. Methods: A nationwide web-based, self-administered anonymous survey was conducted to investigate recruitment and clerkship activities during the coronavirus disease 2019 pandemic. An online questionnaire was sent to 576 obstetrics and gynecology training institutions in Japan between December 21, 2020, and January 31, 2021. Overall, 334 institutions that gave valid responses were included (response rate: 58.0%). Multivariate logistic regression analysis examined the association between online activities, including recruitment and clerkship activities, and the number of new obstetrics and gynecology senior residents in 2021. The stratified analysis by implementing face-to-face activities was conducted to clarify the association. Results: The number of new senior residents increased in 187 facilities (56.0%) and decreased in 147 facilities (44.0%). The facilities that implemented face-to-face and online activities were 185 (55.4%) and 120 (35.9%), respectively. In multivariate logistic regression analysis, an increased number of new obstetrics and gynecology senior residents was significantly associated with face-to-face activities (adjusted odds ratio (AOR)=2.58, 95% confidence interval (CI): 1.11-5.97, p<.001) but not with online activities. In the stratified analysis, online activities were significantly associated with an increased number of new obstetrics and gynecology senior residents among the facilities without face-to-face activities (AOR=3.81, 95% CI: 1.40-10.32, p=.009) but not among those with face-to-face activities (AOR=0.87, 95% CI: 0.42-1.78). Conclusions: Online activities were associated with an increased number of new obstetrics and gynecology senior residents among the facilities that did not conduct face-to-face activities.

Is Adjuvant Chemotherapy Necessary in Patients with Early Endometrial Cancer?

BACKGROUND: We investigated whether there was a difference in prognosis between patients with stage IA endometrial cancer with and without lymphovascular space invasion. METHODS: We enrolled patients with stage IA (pT1aN0M0) endometrial cancer admitted to our hospital from 2009 to 2018. All patients underwent hysterectomy, bilateral salpingo-oophorectomy, and systematic pelvic lymphadenectomy. We immunopathologically evaluated the presence or absence of lymphovascular space invasion in the tumor tissue using hematoxylin and eosin, Elastica-van Gieson, and podoplanin staining. We analyzed disease-free and overall survival and calculated patients' survival distribution using the Kaplan-Meier method and log-rank test. The multivariate analysis was performed to determine the prognostic factors. RESULTS: A total of 116 patients were included. The median age of the patients was 57 (range, 30-78) years, and the histological subtype revealed 98 and 18 cases of types 1 and 2, respectively. The median follow-up period was 71.9 (range, 10.8-149) months, and the 3-year disease-free and 3-year overall survival rates were 94% and 99%, respectively. The disease-free and overall survival rates were significantly shorter in type 2 patients than in type 1 patients (type 2 vs. type 1; 77% vs. 97%, P < 0.01, 94% vs. 100%, P = 0.014, respectively). The univariate and multivariate analyses showed that there were no significant differences in disease-free survival between the lymphovascular space invasion-positive and -negative groups among type 1 cases. CONCLUSION: There was no difference in prognosis between patients with stage IA and type 1 endometrial cancer with and without lymphovascular space invasion.

A simplified procedure of nerve-sparing radical hysterectomy.

AIM: We devised a simplified nerve-sparing radical hysterectomy that is simpler than commonly used procedures. METHODS: We retrospectively examined 16 cases of classical non-nerve-sparing radical hysterectomy (non-nerve-sparing group) and 16 cases of simplified nerve-sparing radical hysterectomy (nerve-sparing group) performed between 2019 and 2020. We examined and compared the duration of surgery, blood loss, perioperative complications, postoperative urinary function (presence or absence of urinary sensation, number of days with residual urine measurement, and frequency and duration of oral sustained release urapidil capsules and self-catheterization), and short-term prognosis between the two groups. RESULTS: Compared to conventional non-nerve-sparing radical hysterectomy, the duration of surgery for nerve-sparing radical hysterectomy was significantly shorter (407 [339-555] min vs. 212 [180-356] min; p < 0.001), and blood loss was significantly less. Compared to the nerve-sparing group, the non-nerve-sparing group had more cases of oral urapidil use and a higher frequency of clean intermittent catheterization. Clean intermittent catheterization was required in two cases in the nerve-sparing group; however, it was withdrawn at 180 and 240 days. Conversely, clean intermittent catheterization was still required in three cases in the non-nerve-sparing group. There were no statistically significant differences in progression-free survival and overall survival between the two groups. CONCLUSION: The simple nerve-sparing radical hysterectomy resulted in shorter duration of surgery and less blood loss as well as in a clear improvement in the postoperative urinary status and short-term prognosis. This technique simplifies nerve-sparing radical hysterectomy, which is commonly thought to be complicated, making it easier to understand.

D-dimer level significance for deep vein thrombosis screening in the third trimester: a retrospective study.

BACKGROUND: Venous thromboembolism often develops after surgery and childbirth, resulting in death in some cases. Although early deep vein thrombosis (DVT) detection can predict pulmonary thromboembolism, there is no early screening method for DVT in pregnant women. Lack of consensus regarding significance or setting and cut-off value interpretation of D-dimer levels further impedes venous thromboembolism screening in pregnant women. This study aimed to examine the utility of third-trimester serum D-dimer levels as a screening test for DVT during pregnancy and to determine the frequency of asymptomatic DVT using lower-limb compression ultrasonography. METHODS: This single-center retrospective study included 497 pregnant women who underwent elective cesarean section at term in our hospital between January 2013 and December 2019. Serum D-dimer levels were preoperatively measured at 32-37 weeks' gestation. The presence or absence of DVT in patients with serum D-dimer levels ≥ 3.0 µg/ml, the cut-off value, was examined using compression ultrasonography. In all patients, the presence or absence of clinical venous thrombosis (symptoms such as lower-limb pain, swelling, and heat sensation) was examined within 4 postoperative weeks. The Royal College of Obstetricians and Gynecologists Guideline 2015 was referred to determine risk factors for the onset of venous thrombosis during pregnancy. Among those, we examined the risk factors for DVT that result in high D-dimer levels during pregnancy. RESULTS: The median age and body mass index were 35 (20-47) years and 21.2 (16.4-41.1) kg/m2, respectively. Further, the median gestational age and D-dimer levels were 37 weeks and 2.1 (0.2-16.0) µg/ml, respectively. Compression ultrasonography was performed on 135 (26.5%) patients with a D-dimer level ≥ 3.0 µg/ml, with none of the patients showing DVT. All patients were followed up for 4 postoperative weeks, with none presenting with venous thromboembolism. Multivariate analysis showed that hypertensive disorders of pregnancy are an independent risk factor for venous thromboembolism that causes high D-dimer levels (odds ratio: 2.48, 95% confidence interval: 1.05-6.50, P = 0.04). CONCLUSION: There may be low utility in screening for DVT using D-dimer levels in the third trimester. Further, prepartum asymptomatic DVT has a low frequency, indicating the low utility of compression ultrasonography.

Changes in serum D-dimer level and effect of enoxaparin sodium after a cesarean section: a retrospective study.

BACKGROUND: Pregnancy increases the risk of venous thromboembolism (VTE). During pregnancy and a post-cesarean section, an increase in D-dimer levels can be observed. However, to date, the usefulness of the D-dimer level measurement for thrombosis in pregnant women has not been determined. OBJECTS: We aimed to evaluate the changes in D-dimer levels after a cesarean section, the risk factors of high D-dimer levels, and enoxaparin sodium's preventive effects on VTE. METHODS: This retrospective study enrolled 160 pregnant women who underwent a cesarean section. D-dimer levels were measured on postoperative day (POD)1 and POD6. If on POD1, the D-dimer levels were ≥10 µg/mL, enoxaparin sodium was administered until POD7. Regardless of enoxaparin administration, when the D-dimer levels on POD6 were ≥10 µg/mL, lower-limb venous ultrasonography was performed. After a cesarean section, patients were screened for the following: factors causing high D-dimer levels, incidence of deep vein thrombosis (DVT), and need for enoxaparin. RESULTS: The median D-dimer levels on POD1 and POD6 were 7.5 µg/mL (1.1-34.1) and 4.2 µg/mL (0.02-31.4), respectively. Enoxaparin sodium was administered to 56 patients (35%). The D-dimer levels on POD6 decreased more significantly than on POD1. The median D-dimer levels in the enoxaparin administration group significantly dropped from 14.3 (POD1) to 3.9 (POD6) (p<.001). The D-dimer levels on POD1 were higher in patients aged ≥35 years and with a hospitalization history of threatened preterm labor. In addition, on POD6, patients aged ≥35 years and with a high body mass index had high D-levels. Following a multivariate analysis, the elderly represent an independent factor for high D-levels. DVT was not observed. CONCLUSION: When the D-dimer levels on POD1 after a cesarean section are ≥10 µg/mL, enoxaparin reduces D-dimer levels six days after cesarean section. Moreover, patients aged ≥35 years represent an independent factor for high D-levels. These findings should be validated by further studies.

Calcified Ovarian Fibromas Complicated with Basal Cell Nevus Syndrome.

Basal cell nevus syndrome (BCNS) is a rare neurocutaneous syndrome characterized by tumorigeneses such as basal cell carcinomas, jaw cysts, ovarian fibromas, and cardiac fibromas. We present a 24-year-old female with calcified ovarian fibromas associated with BCNS. She had a surgical history of the maxillary cyst and was diagnosed with BCNS due to the cutaneous pits. Magnetic resonance imaging indicated an 8-cm mass and a 4-cm mass, which had been suspected to be a subserosal myoma and a fibroma, respectively. GnRH agonist was preoperatively administered; however, the size of the masses did not change. In laparoscopy, a tumor consisting of 8- and 5-cm masses in the right ovary was identified, and tumorectomy was performed. Because both tumors were extraordinarily rigid and could not be morcellated with scalpels or scissors, we removed them by the Luer Bone Rongeurs with minilaparotomy. The histopathological diagnosis was the ovarian fibromas with marked calcification.

Re-classification of uterine cervical cancer cases treated with radical hysterectomy based on the 2018 FIGO staging system.

OBJECTIVE: We re-classified patients with stage IB-II disease (based on the 2008 system) and compared the outcomes with those obtained after using the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system. MATERIALS AND METHODS: We reviewed the data of 154 patients with cervical cancer who underwent radical hysterectomy at our hospital during 2006-2016. Pathological, histological, and radiographic data were used to re-classify the cases based on the 2018 FIGO system. We compared these outcomes to those obtained after using the 2008 FIGO assignments. Overall survival (OS) was calculated from primary therapy initiation until death or the last follow-up examination. RESULTS: The histological types were squamous cell carcinoma (108 cases) and others (46 cases). The 2008 FIGO system assignments were stage IB1, IB2, IIA1, IIA2, and IIB (87, 27, seven, five, and 28 patients, respectively). The new 2018 FIGO system assignments were stage IB1, IB2, IB3, IIA1, IIA2, IIB, and IIIC1 (52, 26, 16, six, three, 21, and 30 patients, respectively). Re-classification to stage IIIC1 disease was observed for previously assigned stage IB1, IB2, IIA1, IIA2, and IIB cases (10, seven, two, two, and nine cases, respectively). The median OS durations based on the 2018 FIGO system were 71.7, 61.1, and 62.3 months for patients with stage IB1, IB2, and IB3 (p = 0.04) disease, respectively. The new stage IB3/IIA2/IIB cases had longer OS than the old stage IB2/IIA2/IIB cases. A positive computed tomography (CT) finding of nodal involvement was observed in 37% of cases with pathological confirmation of pelvic lymph node (LN) involvement. Using CT to identify pelvic LN metastasis had a sensitivity of 37% and specificity of 93%. CONCLUSION: The 2018 FIGO staging system for cervical cancer after radical hysterectomy showed a better ability to differentiate survival outcomes. However, the image evaluation method should be reconsidered.

Differential expression of estrogen receptor subtypes in ovarian high-grade serous carcinoma and clear cell carcinoma.

PURPOSE: To investigate the role of estrogen receptors (ERs) in high-grade serous carcinoma (HGSC) and clear cell carcinoma (CCC) of the ovary and evaluate ERs as prognostic biomarkers for ovarian cancer. METHODS: This study included 79 patients with HGSC (n = 38) or CCC (n = 41) treated at our institution between 2005 and 2014. Immunohistochemistry examined protein expression of ERα, ERß, and G protein-coupled estrogen receptor-1 (GPER-1); relationships between ERα, ERß, and GPER-1 with patient survival were evaluated. Additionally, cell proliferation assay and phosphokinase proteome profiling were performed. RESULTS: In HGSC patients, expression of ERα, cytoplasmic GPER-1, or nuclear GPER-1 was associated with poor progression-free survival (PFS) (P = .041, P = .010, or P = .013, respectively). Cytoplasmic GPER-1 was an independent prognostic factor for PFS in HGSC patients (HR = 2.83, 95% CI = 1.03-9.16, P = .007). ER expressions were not associated with prognosis in CCC patients. GPER-1 knockdown by siRNA reduced the cells number to 60% of siRNA-control-treated cells (P < .05), and GPER-1 antagonist, G-15 inhibited two HGSC cell lines proliferation (KF and UWB1.289) in a dose-dependent manner. Phosphoprotein array revealed that GPER-1 silencing decreased relative phosphorylation of glycogen synthase kinase-3. CONCLUSIONS: High GPER-1 expression is an independent prognostic factor for PFS in HGSC patients, and GPER-1 may play a role in HGSC cell proliferation.

Evaluating the efficacy and safety of ureteral stent placement as a preoperative procedure for gynecological cancer surgeries: A retrospective cohort study.

AIM: To evaluate the efficacy and safety of ureteral stent placement (USP) as a preoperative procedure for gynecological cancer surgeries. METHODS: This was a single-institution retrospective cohort study of 259 patients with gynecological cancer who underwent laparotomy. In 126 patients (USP+ group), a ureteral stent was inserted into the bilateral ureters after the induction of general anesthesia. The remaining 133 patients (USP- group) did not undergo USP. We compared operation time, blood loss, and frequency of laparotomy-related perioperative urinary complications between the groups. The stent was removed 5-7 days postoperatively. Patients were evaluated for signs of hydronephrosis at discharge. The Fisher's exact test was used to investigate the significance of differences in patient characteristics, and multivariate analysis was performed using a Cox proportional hazards model. A p-value of <0.05 was considered statistically significant. RESULTS: There were no significant differences in age and body mass index between the groups. Two patients in the USP- group experienced intraoperative ureteral injury. Total operation time and blood loss were significantly increased in the USP+ group. The risk of bladder tamponade and postoperative hydronephrosis was influenced by USP. USP was unaffected by a history of abdominal surgery, stage of tumor progression, lymphadenectomy type, or hysterectomy type. CONCLUSIONS: The incidence of bladder tamponade and hydronephrosis postoperatively was significantly higher in patients with USP than in those without USP.

Effects of pretreatment radiological and pathological lymph node statuses on prognosis in patients with ovarian cancer who underwent interval debulking surgery with lymphadenectomy following neoadjuvant chemotherapy.

AIM: To analyze whether radiological and pathological lymph node statuses affected prognosis in patients with epithelial ovarian cancer who underwent neoadjuvant chemotherapy followed by interval debulking surgery. METHODS: In total, 82 patients undergoing interval debulking surgery, including systematic retroperitoneal lymphadenectomy, were eligible for this study. We retrospectively analyzed the association among radiological diagnosed retroperitoneal lymphadenopathy by computed tomographic scan before (rLN) and after (yrLN) neoadjuvant chemotherapy, pathological lymph node metastasis (pLN) and prognosis. Patient survival distribution was calculated using the Kaplan-Meier method. RESULTS: There were 36 rLN+ cases (44%); there were no significant differences between rLN+ and rLN- with respect to progression-free survival and overall survival. Progression-free survival and overall survival did not differ between yrLN+ cases and yrLN- cases. Thirty-nine cases (47.5%) were pLN+, and both progression-free survival and overall survival were significantly shorter in pLN+ cases than in pLN- cases (P < 0.001 and P = 0.004, respectively). In univariate analysis, FIGO stage, pLN and surgical completion were prognostic factors for overall survival. Moreover, in multivariate analysis, pLN+ was the independent prognostic factor for progression-free survival (P = 0.001, 95% confidence interval: 1.911-15.69), and pLN and surgical completion were the only independent prognostic factors for overall survival (P = 0.046, P = 0.012). CONCLUSION: Radiological lymph node status may not be a prognostic factor in patients with ovarian cancer who underwent neoadjuvant chemotherapy followed by interval debulking surgery. Pathological lymph node metastasis affects progression-free survival and overall survival.

Long-term evaluation of renal function and neurogenic bladder following radical hysterectomy in patients with uterine cervical cancer.

OBJECTIVE: This study aimed to determine whether radical hysterectomy (RH) affects renal function. METHODS: Renal function was followed up in 83 patients with stage IB1-IIB cervical cancer who underwent RH during 2006-2015. Serum creatinine (sCre) levels were measured preoperatively and every year postoperatively. Estimated glomerular filtration rate (eGFR) was calculated using sCre levels. Patients who were unable to urinate by themselves or whose residual urine was ≥100 mL were referred to a urologist with the diagnosis of neurogenic bladder (NB). The relationship between NB occurrence and changes in sCre level or eGFR was evaluated respectively. RESULTS: Urological intervention was required in 45 patients (54.2%), and self-urethral catheterization was performed in 41 (49.3%) patients. The NB and clean intermittent catheterization (CIC) groups exhibited significant increases in sCre levels, which were not observed in the non-NB or non-CIC groups. In the non-NB group, eGFR did not change following surgery. However, in the NB group, significant decreases in eGFRs were observed at postoperative 2 and 3 years and at final follow-up. There was no difference in the incidence of cardiovascular events between patients with and without NB. CONCLUSION: In patients with NB following RH, a significant decrease in renal function was observed after postoperative 2 years.

Efficacy of panniculectomy-combined surgery in superobese patients with endometrial cancer: A case report and literature review.

INTRODUCTION: Panniculectomy is regarded as an effective approach in highly obese patients with endometrial cancer to improve surgical access or space of the surgical field. PRESENTATION OF CASE: A 66-year-old nulliparous woman was brought in from another hospital to our institute for newly diagnosed endometrial carcinoma. The patient was 158 cm in height and weighed 135.8 kg during the first visit to our hospital. Her body mass Index (BMI) was 54.4 kg/m2. Unfortunately, the patient developed an umbilical hernia and strangulation before the surgery. Emergency partial ileal resection and simple closure of the umbilical hernia were performed. We were finally able to perform simple hysterectomy, and bilateral salpingo-oophorectomy with panniculectomy. Her weight at the time of surgery was 115.5 kg which had been reduced by 20 kg from the time she was first brought in, and the BMI decreased from 54.4 to 45.3 kg/m2. The patient underwent follow-up without adjuvant therapy since she was in the low-risk group, and showed no signs of recurrence 12 months after surgery. DISCUSSION: There are various risks associated with surgery in highly obese patients. Diabetes mellitus, hypertension and smoking are reported to be risk factors of wound complication in panniculectomy, and it was reported that diabetes mellitus was an independent risk factor. CONCLUSION: The combination of panniculectomy was considered as an effective approach to perform safe surgery for obese patients.

Deep vein thrombosis and serum D-dimer after pelvic lymphadenectomy in gynecological cancer.

INTRODUCTION: Venous thromboembolism prevention during the perioperative period requires comprehensive risk-level assessment. The aim of this study was to evaluate the incidence of deep vein thrombosis and to assess the cut-off levels of serum D-dimer as a screening strategy for deep vein thrombosis during the perioperative period. METHODS: A total of 205 patients (ovarian cancer: 68, endometrial cancer: 76, cervical cancer: 61) who underwent gynecological surgery, including retroperitoneal lymph node dissection, were enrolled. We retrospectively analyzed the data on the cut-off value of D-dimer assessed using area under the receiver operating characteristic curve preoperatively, and 2 or 3 months, postoperatively. All patients underwent leg vein ultrasonography regardless of the serum D-dimer level. Furthermore, CT scans were performed to evaluate both disease status and venous thromboembolism, including pulmonary thromboembolism. Statistical analyzes were performed using the Mann-Whitney U-test (D-dimer values of each cancer), Chi-square test, Fisher's exact test (incidence of deep vein thrombosis), and one-way analysis of variance (patient characteristics). RESULTS: A total of 205 patients (ovarian cancer: 68, endometrial cancer: 76, cervical cancer: 61) who underwent gynecological surgery, including retroperitoneal lymph node dissection, were included in the analysis. Deep vein thrombosis rates were significantly higher in patients with ovarian cancer (P<0.001). The postoperative D-dimer value was significantly higher than the preoperative value. Postoperative D-dimer values were also significantly higher in patients who received adjuvant chemotherapy (P=0.001). The cut-off value of D-dimer was 1.55 µg/mL preoperatively (sensitivity, 48.0%; specificity, 94.1%), and this value was higher postoperatively, at 1.95 µg/mL (sensitivity, 37.0%; specificity, 90.9%). CONCLUSION: Postoperative D-dimer values are higher not only after surgery but also in patients who received adjuvant chemotherapy. The cut-off value of D-dimer at 2 or 3 months postoperatively was higher than preoperative value.

Evaluating Chemotherapy-induced Nausea and Vomiting and Food Intake in Patients With Gynecologic Cancer.

BACKGROUND/AIM: Treatments for controlling delayed nausea after chemotherapy are inadequate, potentially inciting malnutrition. We sought to determine the incidence of nausea, anorexia, and food intake after chemotherapy. PATIENTS AND METHODS: Subjects were females with gynecological cancers who underwent chemotherapy between 2008 and 2013. Nausea, anorexia, and food intake in the acute (day 1) and delayed phases (days 2 and 3) were retrospectively evaluated. RESULTS: Subjects included 156 females. Chemotherapies were highly (HEC; n=24) and moderately emetogenic (MEC; n=132). There were no significant between-group differences for anorexia control during either the acute or the delayed phase and both groups demonstrated significantly worse control of nausea during the delayed phase. In the HEC group, food intake was significantly reduced on days 2 and 3 compared with day 1. CONCLUSION: Rates of nausea, anorexia, and food intake significantly worsened over time, particularly in the MEC group. Current supportive therapies appear inadequate and should be improved.

Retroperitoneal Endometrioid Carcinoma Arising from Ureteral Endometriosis.

Primary ureteral endometriosis is considered to be an uncommon form with an incidence of less than 0.1% in endometriosis. We reported a case of retroperitoneal endometrioid carcinoma possibly arising from ureteral endometriosis. A 52-year-old woman complained left backache. A solid mass in left retroperitoneal cavity with hydronephrosis was found. Diagnostic laparotomy with bilateral salpingo-oophorectomy and biopsy of the mass were performed. Although the primary lesion was not defined in the surgery, the histopathological diagnosis of specimen was endometrioid carcinoma. In the interval debulking surgery after the chemotherapy, tumor adjacent the left iliac vessels was observed. We resected the mass together with 5 cm left ureter and performed ureterectomy and anastomosis. The patient was diagnosed as the malignant transformation of ureteral endometriosis. Adjuvant chemotherapy is now undergoing. In case of finding the cancer tissue in women, we should take into account the malignant transformation of less common endometriosis, including ureteral endometriosis.

Serum vascular endothelial growth factor A and vascular endothelial growth factor receptor 2 as prognostic biomarkers for uterine cervical cancer.

BACKGROUND: There are few studies on serum vascular endothelial growth factors and receptors (VEGF/VEGFRs) in patients with uterine cervical cancer (CC). The aim of this study was to determine whether VEGF/VEGFRs could be used as prognostic biomarkers in patients with CC. METHODS: A total of 107 patients with stage IB to IIB CC, who underwent radical hysterectomy at Tottori University Hospital between 2006 and 2015, were included in this study. Serum samples were collected prior to radical hysterectomy, and levels of VEGF-A, VEGF-C, VEGFR-1, and VEGFR-2 were analyzed by enzyme-linked immunosorbent assays. We evaluated the association between the levels of these angiogenic factors and clinicopathologic variables. Survival analysis of 93 patients treated between 2006 and 2013 was performed. RESULTS: The levels of VEGF-A in patients with bulky tumor, pelvic lymph-node involvement (PLNI), and parametrial infiltration (PI) were significantly higher than those in patients without these factors (P = 0.022, P = 0.020, and P = 0.0013, respectively). The overall survival (OS) of patients with high VEGF-A and VEGFR-2 defined by median levels was significantly lower than the OS of patients with low levels of VEGF-A and VEGFR-2 (P = 0.014, P = 0.012, respectively). Multivariate analysis revealed that PLNI, serum VEGF-A levels, and serum VEGFR-2 levels were independent prognostic factors for OS (hazard ratio for VEGF-A 3.42, 95% CI 1.07-13.2; hazard ratio for VEGFR-2 6.37, 95% CI 1.59-43.5). CONCLUSION: Our results suggest that serum VEGF-A and VEGFR-2 may be promising prognostic biomarkers for CC.

Recurrent colon perforation after discontinuation of bevacizumab for ovarian cancer.

Bevacizumab (Bev) is an antiangiogenic drug used to treat various malignances, including ovarian cancer (OC). Bev is generally well-tolerated; however, it has a characteristic toxicity profile. In particular, gastrointestinal perforation (GIP) is a rare but serious side effect that can be lethal. A 55-year-old woman with recurrent OC had an episode of GIP during third-line chemotherapy comprising Bev and topotecan (TPT). Bev was discontinued while TPT was continued as monotherapy. Three months after discontinuation of Bev, the patient presented with left lower abdominal pain and was diagnosed with a second GIP. She had emergent surgery. One year later, she is still alive and healthy, and is continuing TPT. This is the first report of recurrent GIP after discontinuation of Bev. Our case suggests that physicians should be aware of GIP even after the discontinuation of Bev.

Significance of High-Risk Human Papillomavirus Testing for Atypical Glandular Cells on Cervical Cytology.

OBJECTIVES: The aim of this study was to evaluate the diagnostic significance of high-risk human papillomavirus (hrHPV) testing for managing women with atypical glandular cells (AGC) and to explore the distribution of hrHPV genotypes. METHODS: We analyzed cytologic and histopathologic diagnoses in patients referred to our institution due to AGC or atypical squamous cells of undetermined significance (ASC-US). All patients underwent hrHPV testing and genotyping, and positive (PPV) and negative predictive values (NPV) for cervical intraepithelial neoplasia (CIN) 2 or worse [CIN2+/adenocarcinoma in situ (AIS)+] were calculated. RESULTS: Among 41 cases previously diagnosed with AGC, 22 (53%) were classified as CIN2+ (2 squamous cell carcinomas), whereas only 2 were AIS or adenocarcinoma. Twenty-seven (65.8%) cases in the AGC group were hrHPV positive. The most frequent genotypes in both the ASC-US and AGC groups were HPV16 and HPV52. The PPV of hrHPV testing for CIN2+/AIS+ was significantly higher in the AGC than in the ASC-US group (74.1 vs. 35.0%; p = 0.0005). The NPV for CIN2+/AIS+ was significantly lower in the AGC than in the ASC-US group (74.4 vs. 100%; p = 0.0441). CONCLUSION: In patients with AGC, both glandular and squamous lesions must be monitored. hrHPV testing is useful for detecting CIN2+/AIS+ in AGC.
