RESUMEN
AIM: We investigated the frequency of early recurrence of vaginal intraepithelial neoplasia grade 2/3 (VaIN 2/3) (within 2 years) after hysterectomy for cervical intraepithelial neoplasia grade 3 (CIN3). The characteristics of the clinicopathological factors common to them were explored including different surgical methods. METHODS: As a retrospective observational study, a total of 647 CIN3 patients were divided into a conization and hysterectomy group (C group, n = 492; H group, n = 155), and HSIL (CIN2/3 or VaIN2/3) recurrence within 2 years after surgery was evaluated. A stratified analyses was performed. Surgical methods were divided into trans-abdominal, trans-vaginal, and laparoscopic. RESULTS: The recurrence of VaIN3 was detected in four cases (2.6%) in the H group, which was similar to that of CIN2/3 in the C group, 12 out of 491 patients (2.4%). The patients who developed VaIN3 were significantly older than those who did not (median, VaIN3: 71.0; VaIN1 and less: 48.0; p < 0.0001). All VaIN3 cases were detected within 5 months, although majority of cases were negative in the margin (3/4 cases; margin negative). The method of hysterectomy was not related to the VaIN3 recurrence. CONCLUSION: For CIN3 patients for whom hysterectomy is the main treatment, VaIN3 can develop in 2.6% within very shortly after operation even if surgical margin was negative. The elder the age, the higher the risk of early recurrence could be. Laparoscopic surgery is considered to be acceptable methods of hysterectomy.

Polypoid endometriosis (PE) is a rare distinctive variant of endometriosis with morphological features resembling malignant tumors. Although a surgical procedure is usually performed for the treatment and diagnosis of PE, fertility preservation is usually desired in cases of reproductive age. However, there have been no reports of fertility-preserving treatments resulting in live births. In this study, we report three cases of PE that were diagnosed preoperatively or intraoperatively, leading to fertility preservation. Intraoperative pathological diagnosis, hysteroscopy, and hormone therapy before treatment were useful for preoperative diagnosis in the three cases. Two of the three patients got pregnant and the pregnancy progressed to a live birth. We also performed a literature review to identify the clinical characteristics indicative of the preoperative diagnosis of PE.

STUDY OBJECTIVE: To describe a direct approach to the deep uterine vein in laparoscopic radical hysterectomy. DESIGN: Demonstration of the laparoscopic technique with narrated video footage. SETTING: Securing sufficient radicality is extremely important when performing a radical hysterectomy for cervical cancer, either by laparotomy or by minimally invasive surgery. The nerve-sparing Okabayashi radical hysterectomy (NS-RH) was originally aimed at achieving both radical resection and function preservation [1-3]. A key procedure when performing NS-RH is intraoperative identification of the relationship between the deep uterine vein and pelvic splanchnic nerve fibers [4]. With this in mind, a safe and easy method for identifying the crossing point of the deep uterine vein and pelvic splanchnic nerve in the initial phase of the surgery may greatly improve the safety and efficacy of functional preservation in NS-RH. Herein, we describe a minimally invasive "direct approach" to the deep uterine vein. INTERVENTIONS: Before undergoing the pelvic lymphadenectomy, all steps of laparoscopic radical hysterectomy were performed. First, we identified the ureter on the posterior peritoneum, and the peritoneum was dissected just above the ureter. By continuously exploring the pelvic cavity along the ureter, especially through the opening of the space below the ureter in a cranial to caudal direction, we could easily identify the deep uterine vein. This procedure also exposed the fibers of the hypogastric nerve, clarifying the relationship of these structures. CONCLUSION: Because the relationship between the deep uterine vein and nerve fibers is the most important guidepost of this surgery, their identification in the early phase of the surgery enables us to perform the subsequent procedure precisely and securely. This direct approach to the deep uterine vein can be easily and safely performed.

Objective: Endometriosis is associated with various symptoms, but their severity varies from case to case. In this study, we investigated the reality of symptoms presented by patients with clinically early-stage endometriosis-associated ovarian cancer (EAOC) and explored the relationship between symptoms and laboratory/imaging findings, pathological findings, and prognosis. Materials and Methods: This was a retrospective case-control study of patients who received initial surgical treatment and were diagnosed with clinically early-stage EAOC, including ovarian endometrioid carcinoma (OEC), ovarian clear cell carcinoma (OCCC), and seromucinous borderline tumor (SMBT). Patients with OEC/OCCC diagnosed between 2006 and 2016 and those with SMBT diagnosed between 2006 and 2020 were included. Chi-square and Kaplan-Meier estimates were used for statistical analyses. Results: One hundred-seven patients (OEC, n=31; OCCC, n=39; SMBT, n=37) were included. Fifty-nine (55.1%) patients presented with symptoms, and the proportion of patients with OEC who presented with symptoms was significantly higher than that of others (OEC, 77.4%; OCCC, 43.6%; SMBT, 48.6%). The details of symptoms differed significantly among the pathological types (lower abdominal pain/abdominal discomfort/abnormal bleeding, OEC: 11/8/9; OCCC: 6/12/1; SMBT: 15/5/3). Only in the OEC group did symptomatic patients show significantly higher white blood cell (WBC) count and neutrophil/lymphocyte (N/L) ratio (symptomatic vs. asymptomatic, median: WBC count: 7250 vs. 5000, p=0.008; N/L ratio: 4.6 vs. 1.7, p=0.013). None of the asymptomatic patients showed recurrence during follow-up. Conclusion: Patients with EAOC show varying symptoms depending on the histological type of the tumor. Laboratory findings underlying symptoms also vary by histopathological type, which may reflect differences in the carcinogenesis process.
RESUMEN
Uterine adenosarcoma is a rare gynecologic malignancy, and 10-25% of the cases exhibit clinically aggressive behaviors. Although TP53 mutations are frequently identified in high-grade adenosarcomas of the uterus, definitive gene alterations have not been identified in uterine adenosarcomas. Specifically, no reports have described mutations in homologous recombination deficiency-related genes in uterine adenosarcomas. This study presents a case of uterine adenosarcoma without sarcomatous overgrowth but with TP53 mutation that exhibited clinically aggressive behaviors. The patient had an ATM mutation, which is a gene associated with homologous recombination deficiency, and exhibited a good response against platinum-based chemotherapy and possible therapeutic target by poly(ADP-ribose) polymerase inhibitors.
RESUMEN
Para-ovarian cysts are occasionally encountered in clinical practice; however, malignant tumors derived from them are rare. Due to its rarity, the characteristic imaging findings of para-ovarian tumors with borderline malignancy (PTBM) are largely unknown. Herein, we report a case of PTBM, along with imaging findings. A 37-year-old woman came to our department with a suspected malignant adnexal tumor. Pelvic contrast-enhanced magnetic resonance imaging (MRI) revealed a solid part within the cystic tumor with a decrease in the apparent diffusion coefficient (ADC) value (1.16 × 10-3 mm2/s). We also performed Positron Emission Tomography-MRI and showed a strong accumulation of 18F-fluorodeoxyglucose (FDG) in the solid part (SUVmax = 14.8). In addition, the tumor appeared to develop independently of the ovary. Because tumor was derived from para-ovarian cyst, we suspected PTBM preoperatively and planned fertility sparing treatment. Pathological examination revealed a serous borderline tumor and PTBM was confirmed. PTBM can have unique imaging characteristics, including a low ADC value and high FDG accumulation. When a tumor appears to develop from para-ovarian cysts, borderline malignancy can be suspected, even if imaging findings suggest malignant potential.
RESUMEN
There is no consensus on the use of hormone replacement therapy (HRT) after treatment of advanced corpus cancer. We report a case of advanced corpus cancer at a young age, in which HRT was initiated 7 years after surgery, and regional lymph node recurrence was later detected. The patient was 35 years old at the time of initial treatment in X year, when she was diagnosed with stageIIIC2 corpus cancer and underwent a hysterectomy with bilateral salpingo-oophorectomy and a retroperitoneal lymphadenectomy. HRT was started at X + 7 years, and at X + 9 years, a 25 × 12-mm-sized mass was found in the hilum of the right kidney. A laparoscopic resection revealed regional lymph node recurrence of the corpus cancer. A retrospective study further revealed that a tumor measuring 12 × 3 mm was found at X + 3 years and grew to 18 × 7 mm in X + 6 years, just before the start of the HRT. We hypothesize that HRT did not induce tumor recurrence; instead, it allowed for long-term follow-up and early diagnosis.
RESUMEN
Background: Radiological evaluation of para-aortic lymph node metastasis in patients with locally advanced cervical cancer (LACC) possess the risk of missing microscopic metastasis. We commenced laparoscopic para-aortic lymphadenectomy (Lap-PAN) on patients with LACC for surgical staging in 2016. We assessed the feasibility of Lap-PAN in patients with LACC. Methods: We retrospectively reviewed the records of 31 patients with LACC who were staged at International Federation of Gynecology and Obstetrics (FIGO) 2009 IIB to IVA without enlargement of the para-aortic lymph nodes who underwent radiation therapy in our hospital between January 1, 2011 and December 31, 2018. The postoperative outcomes of Lap-PAN were analyzed, and distinct parameters for each patient, including sites of recurrence and disease-free survival, were compared between the Lap-PAN (n = 12) and no surgery (n = 19) groups. Results: The average operation time for Lap-PAN was 167 min, and the estimated blood loss was less than 50 ml in all patients. There were no perioperative complications. The average number of excised lymph nodes was 25, and no pathological metastases were observed. There was no difference in disease-free survival rates between the Lap-PAN and no surgery groups (p = 0.42). During the follow-up period, there were two cases of recurrence in the cervix in the Lap-PAN group, and three and four cases of lung and para-aortic lymph node recurrence, respectively in the no-surgery group. Conclusions: Lap-PAN was safely performed as a pretherapeutic staging method for LACC without worsening patient prognosis. Although Lap-PAN requires a high level of skill, it may be a method to avoid excessive radiation for LACC.

Background: Diffuse uterine leiomyomatosis is a rare disease in which countless, poorly defined, and small nodules are present in most parts of the uterine myometrium. It frequently occurs in fertile women and causes infertility. A deep, median, longitudinal incision of the uterine corpus with the opening of the endometrial cavity, "extensive myomectomy," is required to restore fertility. However, myomectomy may also be a risk factor for perinatal complications. We present a rare case of adhesive small bowel obstruction after extensive myomectomy for diffuse uterine leiomyomatosis. Case: A 37-year-old primigravida presented with sharp epigastric pain and vomiting at 21-week gestation. The patient had a history of extensive myomectomy for diffuse uterine leiomyomatosis. Abdominal radiography revealed moderate air fluid levels in the small intestine, and the patient was diagnosed with adhesive small bowel obstruction. The patient was also diagnosed with placenta previa. Bowel rest with intestinal tube was continued until delivery. Cesarean section was performed at 32-week gestation due to (i) prolonged fasting and total parenteral nutrition for conservative treatment and (ii) fear of sudden massive bleeding from placenta previa. Because the ileum was strongly adherent to the uterine scar from the previous myomectomy, adhesiolysis and enterectomy were performed. The placenta was uncomplicatedly delivered and the hemorrhage was well-controlled. Conclusions: Pregnancy with a history with extensive myomectomy for diffuse uterine leiomyomatosis should be carefully monitored because of the occasional occurrence of adhesive small intestine obstruction during pregnancy.
RESUMEN
It is challenging to preserve the fertility of female patients with B-cell acute lymphoblastic leukemia (B-ALL) before allogeneic hematopoietic stem cell transplantation (allo-HSCT) while maintaining treatment intensity. We report two cases of female patients with Philadelphia chromosome-negative (Ph -) B-ALL whose oocytes were retrieved after controlled ovarian stimulation during and after blinatumomab treatment. The first patient was a 30-year-old woman with relapsed Ph-B-ALL who received prednisolone (PSL) and cytoreductive chemotherapy with cyclophosphamide, vincristine, doxorubicin, and dexamethasone, followed by three courses of blinatumomab bridging to allo-HSCT. Ovarian stimulation was performed twice during blinatumomab administration, and two oocytes were retrieved during each course. The second patient was a 26-year-old woman with newly diagnosed Ph-B-ALL who received PSL, one course of conventional chemotherapy, and one course of high-dose methotrexate and cytarabine followed by two courses of blinatumomab bridging to allo-HSCT. Immediately after completion of the first course of blinatumomab, ovarian stimulation was performed, and three oocytes were retrieved. Use of a 2-week rest period enabled ovarian stimulation and oocyte retrieval to be performed without delaying treatment. Blinatumomab may be an option for preserving fertility while maintaining treatment intensity.

Mature cystic teratoma of the ovary (MCT) occasionally undergoes malignant transformation (MT) that is resistant to chemotherapy and has a poor prognosis. We experienced a case of clinically aggressive MCT-MT that invades surrounding organs and tissues. Although tumor was resected entirely, a rapid tumor recurrence occurred during postoperative chemotherapy (paclitaxel + ifosfamide + cisplatin). The results of comprehensive genomic profiling test performed early in the postoperative period showed a high tumor mutational burden of 23 mutations/Mb. Treatment with nivolumab monotherapy has promptly been initiated and has been very successful for more than one year.
RESUMEN
We report a case of torsion in an otherwise-normal ovary with a giant hematosalpinx. A 23-year-old woman presented with complaints of abdominal pain and nausea. At initial visit, there was few abnormal findings of imaging tests, and we made a diagnosis of ovarian hemorrhage. Three days later, she came back with increased symptoms, and we detected the mass of a complex solid cystic structure with a unilocular cyst much larger than solid component. A diagnostic laparoscopy was performed immediately, and we could make a diagnosis of torsion in an otherwise-normal ovary with a giant hematosalpinx. We performed a salpingectomy and could preserve her ovary. This is the first case of torsion in an otherwise-normal ovary with a giant hematosalpinx which enlarged to a greater extent than the ovary.
RESUMEN
AIM: To ascertain the actual outcomes of oncofertility care in young women to provide more appropriate care. MATERIALS & METHODS: We analyzed the data of 67 female patients under 43 years of age who underwent oncofertility care between January 2015 and September 2019. RESULTS: There were 28 patients with breast cancer, 19 patients with hematologic cancer and 20 patients with other cancer diagnoses. Breast cancer patients tended to take longer than hematologic cancer patients to initiate oncofertility treatment. Despite undergoing oncofertility care, seven of nine pregnant patients did not choose assisted reproductive technology (ART). CONCLUSION: As spontaneous pregnancies were more common than ART pregnancies in our study, pregnancy by not only ART but also non-ART method is a viable option for young cancer survivors.
