Significance of tumor size and number of positive nodes in patients with FIGO 2018 stage IIIC1 cervical cancer.

OBJECTIVE: This study aimed to investigate the prognostic significance of tumor size and number of positive pelvic lymph nodes (PLN) in International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IIIC1 cervical cancer patients. METHODS: Clinical data from 626 women with cervical cancer treated at Osaka International Cancer Center in 2010-2020 were retrospectively reviewed. Using the cutoff value obtained on the receiver operating characteristic analysis, the prognostic significance of tumor size and number of positive PLN in stage IIIC1 patients was first evaluated via uni- and multivariate analyses. Then, the impact of incorporating tumor size and number of positive PLN into the FIGO staging system was investigated using the Kaplan-Meier method. RESULTS: Among 196 women with Stage IIIC1 disease, larger tumors (>4 cm) and multiple PLN metastases (≥4) were independent predictors of progression-free survival (PFS) in patients with stage IIIC1 cervical cancer. The PFS of patients with stage IIIC1 disease was inversely associated with the number of risk factors. Although patients with stage IIIC1 disease had significantly increased survival rates compared to those with stage IIIA or IIIB disease in the original FIGO 2018 staging system, this reversal phenomenon was resolved by incorporating larger tumors (>4 cm) and multiple PLN metastases (≥4) into the revised staging system. CONCLUSIONS: Incorporating tumor size and number of metastatic lymph nodes into the FIGO staging system allows additional risk stratification for women with stage IIIC1 cervical cancer and improves survival prediction performance.

Twenty-five-year mortality trends of four major histological subtypes of cervical cancer: a population-based study using the Osaka cancer registry data.

Objective: To assess the mortality trends of four major histological subtypes of cervical cancer diagnosed between 1994 and 2018. Methods: This population-based retrospective cohort study was conducted using the Osaka Cancer Registry data from 1994 to 2018. A total of 12,003 patients with cervical cancer, squamous cell carcinoma (SCC), adenocarcinoma (A), adenosquamous cell carcinoma (AS), or small cell neuroendocrine carcinoma (SCNEC) were identified. Patients were classified into groups according to the extent of disease (localized, regional, or distant), year of diagnosis (1994-2002, 2003-2010, or 2011-2018), and histological subtype (SCC, A/AS, or SCNEC). Then, their survival rates were assessed using univariate and multivariate analyses. Results: Overall, improved survival rates were observed according to the year of diagnosis in patients with local, regional, and distant cervical cancers. When examined according to the histological subtypes, improved survival rates according to the year of diagnosis were observed in patients with local, regional, and distant SCCs and in those with local and regional A/AS. In patients with distant A/AS, the survival rates did not improve since 2003. In patients with cervical cancer with SCNEC, the survival rates did not improve since 1994 irrespective of the extent of the disease. In the multivariate analysis, non-SCC histology was found to be an independent prognostic factor for OS. Conclusion: In contrast to SCC histology associated with improved survival between 1994 and 2018, SCNEC histology and advanced (stage IVB) A/AS remain to be the unmet medical needs for the management of cervical cancer.

Population-Based Survival Analysis of Stage IVB Small-Cell Neuroendocrine Carcinoma in Comparison to Major Histological Subtypes of Cervical Cancer.

The aim of the current study is to investigate the survival outcome of stage IVB SCNEC of the uterine cervix in comparison to major histological subtypes of cervical cancer. A population-based retrospective cohort study was conducted using the Osaka Cancer Registry data from 1994 to 2018. All FIGO 2009 stage IVB cervical cancer patients who displayed squamous cell carcinoma (SCC), adenocarcinoma (A), adenosquamous cell carcinoma (AS), or small-cell neuroendocrine carcinoma (SCNEC) were first identified. The patients were classified into groups according to the types of primary treatment. Then, their survival rates were examined using the Kaplan-Meier method. Overall, in a total of 1158 patients, clearly differential survival rates were observed according to the histological subtypes, and SCNEC was associated with shortest survival. When examined according to the types of primary treatments, SCNEC was associated with significantly decreased survival when compared to SCC or A/AS, except for those treated with surgery. In patients with FIGO 2009 stage IVB cervical cancer, SCNEC was associated with decreased survival when compared to SCC or A/AS. Although current treatments with either surgery, chemotherapy or radiotherapy have some therapeutic efficacies, to improve the prognosis, novel effective treatments specifically targeting cervical SCNEC need to be developed.

FD-2, an Anticervical Stenosis Device for Patients Undergoing Radical Trachelectomy or Cervical Conization.

This study aimed to introduce FD-2, a newly developed anticervical stenosis device for patients with cervical cancer undergoing radical trachelectomy. Using ethylene-vinyl acetate copolymers, we developed FD-2 to prevent uterine cervical stenosis after radical trachelectomy. The tensile test and extractables and leachables testing were performed to evaluate FD-2's safety as a medical device. FD-2 was indwelled in three patients with cervical cancer during radical trachelectomy and its utility was preliminarily evaluated. FD-2 consists of a head (fish-born-like structure), neck (connecting bridges), and body (tubular structure); the head is identical to FD-1, an intrauterine contraceptive device. FD-2 passed the tensile test and extractables and leachables testing. The average time required for the application or removal of FD-2 in cervical cancer patients was less than 10 s. The median duration of FD-2 indwelling was 8 weeks. No complications, including abdominal pain, pelvic infections, or hemorrhages, associated with FD-2 indwelling were reported. At the 3-12-month follow-up after the radical trachelectomy, no patients developed cervical stenosis or experienced dysmenorrhea. In conclusion, we developed FD-2, a novel device that can be used for preventing cervical stenosis after radical trachelectomy for uterine cervical cancer.

Systematic Review of the Survival Outcomes of Neoadjuvant Chemotherapy in Women with Malignant Ovarian Germ Cell Tumors.

Randomized clinical trials assessing the efficacy of neoadjuvant chemotherapy (NACT) for advanced epithelial ovarian cancer have predominantly included women with high-grade serous carcinomas. The response rate and oncological outcomes of NACT for malignant ovarian germ cell tumors (MOGCT) are poorly understood. This study aimed to examine the effects of NACT on women with MOGCT by conducting a systematic review of four public search engines. Fifteen studies were identified, and a further descriptive analysis was performed for 10 original articles. In those studies, most women were treated with a bleomycin, etoposide, and cisplatin regimen, and one to three cycles were used in most studies. Four studies comparing NACT and primary debulking surgery showed similar complete response rates (n = 2; pooled odds ratio [OR] 0.90, 95% confidence interval [CI] 0.15-5.27), comparable overall survival (n = 3; 87.0-100% versus 70.0-100%), disease-free survival (n = 3; 87.0-100% versus 70.0-100%), recurrence rate (n = 1; OR 3.50, 95%CI 0.38-32.50), and adverse events rate from chemotherapy between the groups. In conclusion, NACT may be considered for the management of MOGCT; however, possible candidates for NACT use and an ideal number of NACT cycles remain unknown. Further studies are warranted to validate the efficacy of NACT in advanced MOGCT patients.

Comparison of the Survival Outcomes of Minimally Invasive Surgery with Open Surgery in Patients with Uterine-Confined and Node-Negative Cervical Cancer: A Population-Based Study.

We aimed to compare the oncological outcomes between Japanese women with uterine-confined and node-negative cervical cancer who underwent open surgery and those who underwent minimally invasive surgery (MIS). A population-based retrospective cohort study was conducted using data from the Osaka Cancer Registry that ranged from 2011 to 2018. A total of 2279 patients who underwent surgical treatment for uterine-confined and node-negative cervical cancer were identified. The patients were classified into groups according to surgery type (open and MIS groups) and year of diagnosis (group one, 2011-2014; group two, 2015-2018). The oncologic outcomes were compared between the MIS and open groups. When the MIS group (n = 225) was compared with open group (n = 2054), overall, there was no significant between-group difference in terms of overall survival. Based on Kaplan-Meier estimates, the probability of overall survival at four years was 99.5% in the MIS group and 97.2% in the open group (p = 0.1110). When examined according to the year of diagnosis, there were no significant between-group differences in the overall survival in both groups one and two. In this population-based cohort study, MIS did not compromise survival outcomes when compared with conventional open surgery in Japanese patients with uterine-confined and node-negative (FIGO 2018 stage I) cervical cancer.

Relationship between Abnormal Placenta and Obstetric Outcomes: A Meta-Analysis.

The placenta has several crucial physiological functions that help maintain a normal pregnancy. Although approximately 2-4% of pregnancies are complicated by abnormal placentas, obstetric outcomes remain understudied. This study aimed to determine the outcomes and prevalence of patients with abnormal placentas by conducting a systematic review of 48 studies published between 1974 and 2022. The cumulative prevalence of circumvallate placenta, succenturiate placenta, multilobed placenta, and placenta membranacea were 1.2%, 1.0%, 0.2%, and 0.004%, respectively. Pregnancies with a circumvallate placenta were associated with an increased rate of emergent cesarean delivery, preterm birth (PTB), and placental abruption compared to those without a circumvallate placenta. The succenturiate lobe of the placenta was associated with a higher rate of emergent cesarean delivery, whereas comparative results were observed in terms of PTB, placental abruption, and placenta previa in comparison to those without a succenturiate lobe of the placenta. A comparator study that examined the outcomes of multilobed placentas found that this data is usually unavailable. Patient-level analysis (n = 15) showed high-rates of abortion (40%), placenta accreta spectrum (40%), and a low term delivery rate (13.3%) in women with placenta membranacea. Although the current evidence is insufficient to draw a robust conclusion, abnormal placentas should be recognized as a high-risk factor for adverse outcomes during pregnancy.

Evaluation of survival outcomes between minimally invasive and open surgery in the treatment of early-stage endometrial cancer: a population-based study in Osaka Japan.

OBJECTIVE: To compare the oncological outcomes between Japanese women who underwent minimally invasive surgery and those who underwent open surgery for early-stage endometrial cancer. METHODS: This population-based retrospective cohort study was conducted using data from the Osaka Cancer Registry from 2011 to 2018. Surgically treated patients for localized (uterine-confined) endometrial cancer were identified. Patients were classified into two groups according to the type of surgery (minimally invasive surgery group and open-surgery group), pathological risk factors (low-risk and high-risk), and year of diagnosis (Group 1, 2011-14; Group 2, 2015-18). Overall survival was compared between the minimally invasive surgery and open-surgery groups. RESULTS: In the analyses including all patients, there was no difference in overall survival between the minimally invasive surgery and open-surgery groups (P = 0.0797). The 4-year overall survival rate was 97.1 and 95.7% in the minimally invasive surgery and open-surgery groups, respectively. When investigated according to pathological risks, there were no differences in overall survival between the minimally invasive surgery and open-surgery groups in both the low- and high-risk groups. In the low-risk group, the 4-year overall survival rates in the minimally invasive surgery and open-surgery groups were 97.7 and 96.5%, respectively. In the high-risk group, the 4-year overall survival rates in the minimally invasive surgery and open-surgery groups were 91.2 and 93.2%, respectively. Similarly, there were no differences in overall survival between the minimally invasive surgery and open-surgery groups in both Group 1 (P = 0.4479 in low-risk and P = 0.1826 in high-risk groups) and Group 2 (P = 0.1750 in low-risk and P = 0.0799 in high-risk groups). CONCLUSION: Our study provides epidemiological evidence that minimally invasive surgery is an effective alternative to open surgery in Japanese patients with early-stage endometrial cancer.

[Safety and Efficacy of Robot-Assisted Surgery for Early Uterine Cancer in Our Institution over Five Years Since Its Introduction].

Lacking experience of laparoscopic surgery against gynecologic malignancies, we started performing robot-assisted surgery for uterine cancer in September 2017. Here we compared the safety and efficacy of robot-assisted surgery with those of open surgery in early-stage uterine cancer patients. The surgical time was significantly longer and the blood loss and hospital stay were significantly shorter for robot-assisted versus open surgery. No recurrence was observed after robot-assisted surgery. Robot-assisted surgery can be safely performed even in general hospitals and is an effective treatment option for early-stage uterine cancer patients.

Spontaneous bladder rupture attributable to a radical hysterectomy-associated neurogenic bladder in patients with cervical cancer: A case report and literature review.

INTRODUCTION AND IMPORTANCE: Spontaneous bladder rupture (SBR) is an extremely rare urological emergency. Herein we report a rare case of SBR in a postoperative cervical cancer patient, which was attributable to bladder distension due to a radical hysterectomy-associated neurogenic bladder. CASE PRESENTATION: A 74-year-old nulliparous Japanese patient with cervical cancer (pT1b3N0M0) presented with acute abdominal pain nine days after a radical hysterectomy. The pretreatment workup included plain computed tomography (CT) revealed the presence of ascites in the absence of gastrointestinal perforation. The patient was initially diagnosed with generalized bacterial peritonitis and treated with antibiotics. Urine outflow was noted 5 days later from the vaginal stump. Subsequent contrast-enhanced CT demonstrated a bladder wall defect with presence of contrast medium in the abdominal cavity. The patient was diagnosed with SBR and was conservatively treated with antibiotics and prolonged catheterization (4 weeks); these measures showed no signs of therapeutic efficacy. The patient was subsequently treated surgically with an ileal conduit urinary diversion. The patient is currently free of disease. CLINICAL DISCUSSION: A literature review revealed that a history of pelvic radiotherapy is the main predisposing factor for SBR in women with cervical cancer. Our case serves to alert physicians that SBR should be considered a differential diagnosis in postoperative cervical cancer patients without a history of pelvic radiotherapy who experience generalized peritonitis symptoms or present as an acute abdomen. CONCLUSION: SBR can develop in cervical cancer patients without a history of radiotherapy. This differential diagnosis should be considered in patients with a radical hysterectomy-associated neurogenic bladder.

Impact of lymphadenectomy in patients with locally recurrent or persistent cervical cancer treated with salvage hysterectomy.

AIM: To investigate the role of lymphadenectomy (LND) in locally recurrent or persistent cervical cancer patients treated with salvage hysterectomy. METHODS: Locally recurrent or persistent cervical cancer patients treated with salvage hysterectomy, with or without LND, were identified. Patients were divided into two groups according to the status of radiologic evidence of lymph node metastasis, and the impact of LND was investigated by evaluating postoperative survival. RESULTS: This study included 72 patients; 48 did not show radiological evidence of lymph node metastasis (Group 1) while 24 did (Group 2). Overall, the addition of LND to salvage hysterectomy resulted in increased postoperative complications. In Group 1, salvage hysterectomy plus LND resulted in the identification of five cases with false-negative lymph nodes (19.2%), but showed no advantage over salvage hysterectomy alone in terms of postoperative survival. In Group 2, all patients underwent LND, which resulted in the identification of eight cases with false-positive nodes (33.3%), and reasonably long postoperative survival. The estimated 3-year postoperative survival rate in this group was 39.7%. CONCLUSION: Including LND in salvage hysterectomy allows for precise lymph node staging but increases risk of postoperative complications. However, considering the inability to improve survival, LND should not be performed during salvage hysterectomy in patients without radiological evidence of lymph node metastasis. In patients with radiological evidence of lymph node metastasis, salvage hysterectomy plus LND can only be performed in those who understand the risk of postoperative complications and the limited evidence supporting its survival advantage.

The Characteristics and Obstetric Outcomes of Type II Vasa Previa: Systematic Review and Meta-Analysis.

Vasa previa is a rare fetal life-threatening obstetric disease classified into types I and II. This study aimed to examine the characteristics and obstetric outcomes of type II vasa previa. A systematic review was performed, and 20 studies (1998-2022) were identified. The results from six studies showed that type II vasa previa accounted for 21.3% of vasa previa cases. The characteristics and obstetric outcomes (rate of assisted reproductive technology (ART), antenatal diagnosis, emergent cesarean delivery, maternal transfusion, gestational age at delivery, and neonatal mortality) were compared between type I and II vasa previa, and all outcomes of interest were similar. The association between ART and abnormal placenta (bilobed placenta or succenturiate lobe) was examined in three studies, and the results were as follows: (i) increased rate of succenturiate lobes (ART versus non-ART pregnancy; OR (odds ratio) 6.97, 95% confidence interval (CI) 2.45-19.78); (ii) similar rate of abnormal placenta (cleavage-stage versus blastocyst embryo transfer); (iii) increased rate of abnormal placenta (frozen versus fresh embryo transfer; OR 2.97, 95%CI 1.10-7.96). Although the outcomes of type II vasa previa appear to be similar to those of type I vasa previa, the current evidence is insufficient for a robust conclusion.

Surgical Management for Transposed Ovarian Recurrence of Cervical Cancer: A Systematic Review with Our Experience.

In early-stage cervical cancer, ovarian metastasis is relatively rare, and ovarian transposition is often performed during surgery. Although rare, the diagnosis and surgical approach for recurrence at transposed ovaries are challenging. This study focused on the diagnosis and surgical management of transposed ovarian recurrence in cervical cancer patients. A 45-year-old premenopausal woman underwent radical hysterectomy, bilateral salpingectomy, and pelvic lymphadenectomy following postoperative concurrent chemoradiotherapy for stage IB1 cervical cancer. During the initial surgery, the ovary was transposed to the paracolic gutter, and no postoperative complications were observed. Ovarian recurrence was diagnosed using positron emission tomography-computed tomography, and a laparoscopic bilateral oophorectomy was performed. A systematic review identified nine women with transposed ovarian recurrence with no other metastases of cervical cancer, and no studies have discussed the optimal surveillance of transposed ovaries. Of those (n = 9), four women had died of the disease within 2 years of the second surgery, and the prognosis of transposed ovarian cervical cancer seemed poor. Nevertheless, three women underwent laparoscopic oophorectomies, none of whom experienced recurrence after the second surgery. Few studies have examined the surgical management of transposed ovarian recurrence. The optimal surgical approach for transposed ovarian recurrence of cervical cancer requires further investigation.

Herlyn-Werner-Wunderlich syndrome (HWWS)-associated gynecological malignancies: A case report and literature review.

Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare congenital urogenital anomaly characterized by uterine didelphys, unilateral blind hemivagina, and ipsilateral renal agenesis. We present a very rare case of HWWS-associated cervical cancer in which the presence of a genital anomaly was not noticed until the patient experienced postmenopausal vaginal bleeding. A 74-year-old nulliparous Japanese woman presented with vaginal bleeding. Pre-treatment workup revealed uterine didelphys, obstructed hemivagina/hemicervix, renal agenesis, and cancer development from the remnant-obstructed hemivagina/hemicervix. The patient was diagnosed with HWWS and HWWS-associated vaginal or cervical cancer, treated with radical surgery, and a diagnosis of clear cell carcinoma (CCC) of the uterine cervix was histopathologically confirmed. A literature review revealed an increased incidence of CCC in women with HWWS.

Significance of the Number and the Location of Metastatic Lymph Nodes in Locally Recurrent or Persistent Cervical Cancer Patients Treated with Salvage Hysterectomy plus Lymphadenectomy.

We retrospectively investigated the significance of metastatic lymph nodes in patients with locally recurrent or persistent cervical cancer in a previously irradiated field and subsequently had salvage hysterectomy. Clinical data were obtained from a chart review, and the prognostic impact of the presence, number (1-2 versus ≥3), and location (pelvic versus pelvic plus para-aortic) of lymph node metastasis was investigated by comparing recurrence and survival. In total, 50 patients were included in this study, of which 21 (42.0%) showed pathological evidence of lymph node metastasis (node-positive group). Both the univariate and multivariate analyses showed that lymph node metastasis was an independent prognostic factor for postoperative recurrence (hazard ratio (HR) 5.36; 95% CI 1.41-6.66; p = 0.0020). The predominant sites of recurrence after salvage surgery were the visceral organs and lymph nodes in the node-negative and node-positive groups, respectively. Patients with ≥3 node metastases showed similar survival to those with 1-2 node metastases. Patients with pelvic node metastasis showed similar survival to those with pelvic and para-aortic node metastases. The presence, not number or location, of lymph node metastasis was an independent poor prognostic factor for post-operative recurrence in patients who developed locally recurrent or persistent cervical cancer treated with salvage hysterectomy plus lymphadenectomy.

Assisted Reproductive Technique and Abnormal Cord Insertion: A Systematic Review and Meta-Analysis.

Abnormal cord insertion (ACI) is associated with adverse obstetric outcomes; however, the relationship between ACI and assisted reproductive technology (ART) has not been examined in a meta-analysis. This study examines the association between ACI and ART, and delivery outcomes of women with ACI. A systematic review was conducted, and 16 studies (1990-2021) met the inclusion criteria. In the unadjusted pooled analysis (n = 10), ART was correlated with a higher rate of velamentous cord insertion (VCI) (odds ratio (OR) 2.14, 95% confidence interval (CI) 1.64-2.79), marginal cord insertion (n = 6; OR 1.58, 95%CI 1.26-1.99), and vasa previa (n = 1; OR 10.96, 95%CI 2.94-40.89). Nevertheless, the VCI rate was similar among the different ART types (blastocyst versus cleavage-stage transfer and frozen versus fresh embryo transfer). Regarding the cesarean delivery (CD) rate, women with VCI were more likely to have elective (n = 3; OR 1.13, 95%CI 1.04-1.22) and emergent CD (n = 5; OR 1.93, 95%CI 1.82-2.03). In conclusion, ART may be correlated with an increased prevalence of ACI. However, most studies could not exclude confounding factors; thus, further studies are warranted to characterize ART as a risk factor for ACI. In women with ACI, elective and emergent CD rates are high.

Safety and efficacy of Ninjin'yoeito along with iron supplementation therapy for preoperative anemia, fatigue, and anxiety in patients with gynecological disease: an open-label, single-center, randomized phase-II trial.

BACKGROUND: Preoperative anemia affects perioperative outcomes and often causes fatigue and psychological disorders. Therefore, anemia should be treated before a patient undergoes surgery. Ninjin'yoeito (NYT), a Japanese Kampo medicine composed of ginseng and Japanese angelica root with the other 10 herbs, is administered for anemia, fatigue and anxiety; however, there are a few reports that have prospectively examined the effects of NYT before surgery for gynecological diseases. Hence, we tended to investigate its efficacy and safety. METHODS: In this open-label randomized trial, women with gynecological diseases accompanied by preoperative anemia (defined as < 11.0 g/dL Hemoglobin [Hb]) were randomly assigned (1:1) into the iron supplementation and NYT groups. Patients of the iron supplementation group and the NYT group received 100 mg/day iron supplementation with and without NYT (7.5 g/day) for at least 10 days before surgery. The primary endpoint was improvement in Hb levels before and after treatment, and Cancer Fatigue Scale (CFS) and Visual Analogue Scale for Anxiety (VAS-A) scores between groups. Statistical analyses were performed with Wilcoxon signed rank test, Wilcoxon rank sum test, and Fisher's exact test as appropriate. RESULTS: Forty patients were enrolled of whom 30 patients were finally analyzed after allocating 15 to each group. There was no difference in the characteristics between both groups. Hb significantly increased in both groups (iron supplementation group, 9.9 ± 0.8 g/dL vs. 11.9 ± 1.6 g/dL; NYT group, 9.8 ± 1.0 g/dL vs. 12.0 ± 1.0 g/dL); the difference in the elevations in Hb between both groups was statistically insignificant (P = 0.72). Contrarily, CFS (17.9 ± 10.2 vs. 8.1 ± 5.2) and VAS-A (56 mm (50-70) vs. 23 mm (6-48)) scores were significantly decreased only in the NYT group and these changes were greater in the NYT group (∆CFS, P = 0.015; ∆VAS-A, P = 0.014). Liver dysfunction occurred in one patient of the NYT group. CONCLUSIONS: For treating preoperative anemia in women with gynecological conditions, NYT administration along with iron supplementation safely and efficiently improved the preoperative fatigue and anxiety in addition to the recovery from anemia. TRIAL REGISTRATION: jRCT1051190012 (28/April/2019, retrospectively registered).

Primary Fallopian Tube Carcinoma Presenting with a Massive Inguinal Tumor: A Case Report and Literature Review.

Primary fallopian tube carcinoma (PFTC) has characteristics similar to those of ovarian carcinoma. The typical course of PFTC metastasis includes peritoneal dissemination and pelvic and paraaortic lymph node metastasis, while inguinal lymph node metastasis is rare. Moreover, the initial presentation of PFTC with an inguinal tumor is extremely rare. A 77-year-old postmenopausal woman presented with a massive 12-cm inguinal subcutaneous tumor. After tumor resection, histopathological and immunohistochemical analysis showed that the tumor was a high-grade serous carcinoma of gynecological origin. Subsequent surgery for total hysterectomy with bilateral salpingo-oophorectomy revealed that the tumor developed in the fallopian tube. She received adjuvant chemotherapy with carboplatin and paclitaxel, followed by maintenance therapy with niraparib. There has been no recurrence or metastasis 9 months after the second surgery. We reviewed the literature for cases of PFTC and ovarian carcinoma that initially presented with an inguinal tumor. In compliance with the Preferred Reporting Items for Systematic Reviews guidelines, a systematic literature search was performed through 31 January 2022 using the PubMed and Google scholar databases and identified 14 cases. In half of them, it was difficult to identify the primary site using preoperative imaging modalities. Disease recurrence occurred in two cases; thus, the prognosis of this type of PFTC appears to be good.

The Effect of Surgeon Volume on the Outcome of Laser Vaporization: A Single-Center Retrospective Study.

Although laser vaporization is a popular minimally invasive treatment for cervical intraepithelial neoplasia (CIN), factors influencing CIN recurrence are understudied. Moreover, the effect of surgeon volume on patients' prognosis after laser vaporization for CIN is unknown. This single-center retrospective study evaluated the predictive value of surgeon volume and patient characteristics for laser vaporization outcomes in women with pathologically confirmed CIN2. Histologically confirmed CIN2 or higher grade after laser vaporization was defined as persistent or recurrent. Various patient characteristics were compared between women with and those without recurrence to examine the predictive factors for laser vaporization. There were 270 patients with a median age of 36 (18-60) years. The median follow-up period was 25 (6-75.5) months and the median period between treatment and persistence or recurrence was 17 (1.5-69) months. The median annual number of procedures for all seven surgeons was 7.8. There were 38 patients (14.1%) with persistent or recurrent lesions-24 had CIN2, 13 had CIN3, and one had adenocarcinoma in situ. Patient age, body mass index, surgeon volume, and history of prior CIN treatment or invasive cervical cancer were not significantly correlated with lesion persistence or recurrence. In conclusion, laser vaporization has comparable success rates and is a feasible treatment for both low- and high-volume surgeons.

Iliac artery-enteric fistula developed during bevacizumab-containing chemotherapy for recurrent cervical cancer: A case report and literature review.

An arterioenteric fistula is a devastating and life-threatening condition. As patients often present in extremis from hemorrhage shock, an early diagnosis and prompt life-saving interventions have to be performed. In this report, we describe a case of a 38-year-old Japanese woman who presented with hematochezia that rapidly progressed to hemorrhagic shock secondary to an iliac artery-enteric fistula that developed during bevacizumab-containing chemotherapy for recurrent cervical cancer. The patient underwent successful endovascular treatment with a covered stent-graft as a bridge to definitive open surgery.
