- Extrauterine choriocarcinoma is uncommon and may be mistaken for a ruptured ectopic pregnancy. Rapid diagnosis is essential, as massive intraperitoneal bleeding can be fatal. Once histologically diagnosed, choriocarcinoma is highly chemosensitive. This case describes a 38-year-old woman who presented with sudden lower abdominal pain. Six weeks after her last menstrual period, serum human chorionic gonadotropin (hCG) was 28,834 mIU/mL. No intra-uterine gestational sac was found, and intraperitoneal bleeding was observed, suggesting an ectopic pregnancy. An emergency laparoscopic surgery revealed a blood clot and active bleeding on the peritoneal surface near the ileocecal region, which was resected. Histology revealed sheets of syncytiotrophoblasts and intermediate trophoblast cells without villi, and immunohistochemistry was diffusely positive for Ki-67 and hCG, confirming primary peritoneal choriocarcinoma. Staging imaging revealed no other lesions. The patient received four cycles of MEA chemotherapy (methotrexate, etoposide, actinomycin D) at three-week intervals, resulting in sustained hCG normalization and no evidence of recurrence at follow-up. Primary peritoneal choriocarcinoma should be considered in the differential diagnosis of intraperitoneal bleeding during early pregnancy. Even when ectopic pregnancy is suspected, the excised tissue must be submitted for histopathological examination so that chemotherapy can be initiated promptly in case of choriocarcinoma.2025年06月, Cureus, 17(6) (6), e86529, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: The effectiveness of local treatment in lymph node metastasis from uterine cancer has been proven; the standard treatment is surgical intervention. Although radiotherapy, including particle radiotherapy (PRT), is an alternative local treatment, its application is often contraindicated owing to its proximity to the gastrointestinal tract. Combination treatment with spacer placement surgery followed by PRT is a potential solution to this problem. This study aimed to evaluate the outcomes of this combination treatment of lymph node metastases from uterine cancer. PATIENTS AND METHODS: Between December 2007 and March 2023, ten consecutive patients who underwent combination treatment comprising spacer placement surgery and subsequent PRT were assessed for treatment outcomes. RESULTS: The median survival time was 53.5 months; the 3- and 5-year overall survival rates were 76.2% and 38.1%, respectively. The 3- and 5-year local control rates in all patients were both 88.9%. The median volume irradiated at 95% of the treatment planning dose (V95%) of the gross tumor volume, clinical target volume, and planning target volume were 100.0%, 99.8%, and 92.2%, respectively. The median dose intensity covering 95% of the target volume (D95%) of the gross tumor volume/planned dose, clinical target volume/planned dose, and planning target volume/planned dose were 98.9%, 99.0%, and 87.2%, respectively. CONCLUSIONS: Spacer placement surgery contributed to the optimized PRT dose distribution and might have contributed to favorable local control and survival rates. This innovative combination treatment might have a significant effect on the treatment of lymph node metastases from uterine cancers.2025年06月, Annals of surgical oncology, 32(6) (6), 4313 - 4321, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: The Geriatric-8 (G8) is a validated screening tool for identifying frailty in elderly cancer patients. Although minimally invasive surgery (MIS) is increasingly performed in older adults with gynecologic malignancies, few studies have evaluated the association between G8 scores and perioperative complications in this setting. METHODS: This single-center retrospective study included patients aged ≥ 65 years who underwent MIS for gynecologic malignancies between January 2019 and March 2024. G8 scores were retrospectively calculated using medical records, with a threshold of ≤ 12.5 indicating geriatric risk. Perioperative complications were defined as either (1) Clavien-Dindo classification or CTCAE version 5 grade II or higher within 30 days postoperatively or (2) the need for rehabilitation intervention due to a decline in activities of daily living (ADL). Univariate and multivariate logistic regression analyses were conducted to identify associated factors. RESULTS: A total of 68 patients were included (median age: 72.5 years). The median G8 score was significantly lower in the complication group than in the non-complication group (12.5 vs. 14.5, p = 0.008). In multivariate analysis, a G8 score ≤ 12.5 was independently associated with perioperative complications (OR: 4.02, 95% CI: 1.38-11.70, p = 0.011). No significant associations were found for operative time, hysterectomy, or lymphadenectomy. CONCLUSION: A low G8 score was independently associated with perioperative complications and may be useful for preoperative risk assessment in elderly patients undergoing MIS for gynecologic malignancies.2025年, Asian journal of endoscopic surgery, 18(1) (1), e70098, 英語, 国内誌研究論文(学術雑誌)
- Macrophages in the tumor microenvironment, termed tumor-associated macrophages (TAMs), promote the progression of various cancer types. However, many mechanisms related to tumor-stromal interactions in epithelial ovarian cancer (EOC) progression remain unclear. High-grade serous ovarian carcinoma (HGSOC) is the most malignant EOC subtype. Herein, immunohistochemistry was performed on 65 HGSOC tissue samples, revealing that patients with a higher infiltration of CD68+, CD163+, and CD204+ macrophages had a poorer prognosis. We subsequently established an indirect co-culture system between macrophages and EOC cells, including HGSOC cells. The co-cultured macrophages showed increased expression of the TAM markers CD163 and CD204, and the co-cultured EOC cells exhibited enhanced proliferation, migration, and invasion. Cytokine array analysis revealed higher YKL40 secretion in the indirect co-culture system. The addition of YKL40 increased proliferation, migration, and invasion via extracellular signal-regulated kinase (Erk) signaling in EOC cells. The knockdown of integrin β4, one of the YKL40 receptors, suppressed YKL40-induced proliferation, migration, and invasion, as well as Erk phosphorylation in some EOC cells. Database analysis showed that high-level expression of YKL40 and integrin β4 correlated with a poor prognosis in patients with serous ovarian carcinoma. Therefore, the YKL40/integrin β4 axis may play a role in ovarian cancer progression.2024年10月, International journal of molecular sciences, 25(19) (19), 英語, 国際誌研究論文(学術雑誌)
- OBJECTIVE: This study elucidated the efficacy of Relugolix (REL) on the reduction of uterine volume and clinical symptoms for the treatment of adenomyosis. METHODS: We conducted a retrospective cohort study of patients who received REL (40 mg for about 20 weeks) and who underwent a hysterectomy for adenomyosis or fibroids. We divided patients into two groups: adenomyosis coexisting with fibroids (Group A) and fibroids only (Group B); the groups were determined by a postoperative pathological examination. The primary end points were the percent reduction in uterine volume, adenomyotic lesion, and the largest fibroid volume at week 16. The secondary end points were the rate of amenorrhea, pelvic pain, and anemia at week 12. RESULTS: A total of 56 patients participated in the current study: 20 in Group A and 36 in Group B. Regarding the largest fibroid volume, there was no significant difference between the two groups. Uterine volume after REL treatment was significantly decreased in Group A (43%), as compared to Group B (27%) (p = .00972), In Group A, adenomyotic lesion was decreased by 61%. Irrespective of the group, adenomyosis showed a significant reduction compared to uterine fibroids (p < .001). There was no statistically significant difference in the mitigation of symptoms (amenorrhea, pelvic pain, and anemia) between the two groups. CONCLUSIONS: REL is more effective in reducing adenomyotic lesion than uterine fibroids and in relieving symptoms (amenorrhea, pelvic pain, and anemia). It can be expected that REL will also be used as a preoperative treatment for adenomyosis.2023年12月, Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 39(1) (1), 2237121 - 2237121, 英語, 国際誌研究論文(学術雑誌)
- INTRODUCTION AND IMPORTANCE: A case of Low-grade endometrial stromal sarcoma (LG-ESS) invading the great vessels is rare. CASE PRESENTATION: A 34-year-old female who had no past history presented to a previous hospital with abdominal distension. Magnetic resonance imaging revealed a 15 cm pelvic mass beside the uterus, and only the pelvic mass was removed at the surgery. The tumor was judged to be a LG-ESS. The patient chose to be observed to preserve her fertility, and no adjuvant treatment was undertaken. Two years later, she was referred to our hospital due to recurrence of the pelvic mass. Enhanced computed tomography revealed a large tumor in the vena cava which extended from the left internal iliac vein and which originated from the pelvic tumor. An operation was performed by a multidisciplinary team. Complete resection of the tumor was achieved with a radical hysterectomy, bilateral salpingo-oophorectomy, removal of recurrent pelvic masses and the intravascular tumor. We diagnosed a recurrence of LG-ESS. She received a postoperative adjuvant therapy of LG-ESS. CLINICAL DISCUSSION: Patients with fertility-sparing treatment had higher recurrence rates. In cases of tumor intravenous extension, we should make every effort to extract the tumor to avoid sudden death. CONCLUSION: This case highlights the importance of a multidisciplinary approach in treating this rare tumor with intravascular extension. In particular, patients with LG-ESS who receive fertility-sparing surgery should undertake postoperative chemotherapy or radiotherapy in order to reduce the risk of recurrence, as was in this case.2023年10月, International journal of surgery case reports, 111, 108857 - 108857, 英語, 国際誌研究論文(学術雑誌)
- Intramural pregnancy is a rare form of ectopic pregnancy. It is defined by a gestation within the uterine wall, completely surrounded by myometrium and separated from the uterine cavity and the fallopian tube. We report a rare case of intramural ectopic pregnancy. If a patient has a history of intrauterine surgery or myomectomy, the possibility of intramural pregnancy, although rare, should not be ruled out.2023年01月, Asian journal of endoscopic surgery, 英語, 国内誌[査読有り]
- BACKGROUND: Serous endometrial intraepithelial carcinoma (SEIC) is now considered to represent an early stage of uterine serous carcinoma (USC). It is an intraepithelial lesion but has been reported to cause extrauterine metastases. We report a case of SEIC with serous ovarian carcinoma and lymph node metastasis. CASE PRESENTATION: A 57-year-old post-menopausal woman (gravida 3, para 2, SA1) was referred to our hospital with lower abdominal pain. An ultrasound and MRI showed that the ovary had swollen to 8 cm in size and had a solid lesion. The uterus was normal. The patient underwent exploratory laparoscopy on the suspicion of torsion of the ovarian tumor. Intraoperative findings showed a right ovarian tumor, but no ovarian tumor torsion was observed. A small amount of bloody ascites was found in the Douglas fossa, and bleeding was observed from the tumor itself. A right salpingo-oophorectomy was then performed. Histopathological results revealed a high-grade serous carcinoma. Forty days after the first surgery, we performed a staging laparotomy: a total abdominal hysterectomy, left salpingo-oophorectomy, systematic pelvic and paraaortic lymphadenectomy, and a partial omentectomy. A complete cytoreduction was achieved. In the pathological examination, the invasion of the serous carcinoma was observed in the left ovarian ligament, and lymph node metastasis was found in the paraaortic lymph nodes. Atypical columnar cells formed irregular papillary lesions which had proliferated in the endometrium, and this was diagnosed as SEIC. The final diagnosis was serous ovarian cancer, FIGO stage IIIA1(ii), pT2bN1M0, with SEIC. CONCLUSION: We report a case of SEIC with synchronous serous carcinoma of the adnexa uteri. Both were serous carcinomas and, thus, it was difficult to identify the primary lesion. The distinction between metastatic cancer and two independent primary tumors is important for an accurate diagnosis and tumor staging. Histological diagnostic criteria remain controversial, and further development of a method for differentiating between both diseases is required.2021年06月, Journal of ovarian research, 14(1) (1), 87 - 87, 英語, 国際誌研究論文(学術雑誌)
- Human herpesvirus 6 (HHV-6) infects over 90% of people. The HHV-6 subtype, HHV-6B in particular, is often associated with exanthem subitum in early childhood. Exanthem subitum is usually self-limiting and good prognosis disease; however, some infants primarily infected with HHV-6B develop encephalitis/encephalopathy, and half of the patients developed encephalopathy reported to have neurological sequelae. Furthermore, after primary infection, HHV-6B remains in a latent state and sometimes reactivated in immunosuppressed patients, causing life-threatening severe encephalopathy. However, effective immunotherapies or vaccines for controlling HHV-6B infection and reactivation have not yet been established. Recently, we have found that the HHV-6B tetrameric glycoprotein (g) complex, gH/gL/gQ1/gQ2 is a promising vaccine candidate, and currently under preclinical development. To confirm our vaccine candidate protein complex induce detectable T-cell responses, in this study, we comprehensively screened CD4+ and CD8+ T-cell epitopes in the gH/gL/gQ1/gQ2 tetrameric complex protein in mice immunisation model. Both BALB/c and C57BL/6 mice were immunised with the tetrameric complex protein or plasmid DNA encoding gH, gL, gQ1, and gQ2, and then restimulated with 162 20-mer peptides covering the whole gH/gL/gQ1/gQ2 sequences; multiple CD4+ and CD8+ T-cell-stimulating peptides were identified in both BALB/c and C57BL/6 mice. Our study demonstrates that gH/gL/gQ1/gQ2 tetramer-targeted vaccination has potential to induce T-cell responses in two different strains of mice and supports the future development and application of T-cell-inducing vaccine and immunotherapies against HHV-6B.2020年, Journal of immunology research, 2020, 4697529 - 4697529, 英語, 国際誌研究論文(学術雑誌)
- Primary peritoneal carcinosarcomas which arise from extragenital locations are extremely rare. Carinosarcomas contain both carcinomatous and sarcomatous elements and can be mainly detected in the female genital tract. We herein report a case of primary peritoneal carcinosarcoma diagnosed by laparoscopic surgery and treated with olaparib. A 62-year-old woman referred to our hospital due to abdominal distension. From imaging findings, we suspected advanced primary peritoneal carcinoma, and laparoscopic surgery was thereafter performed. The pathological diagnosis was carcinosarcoma, and the patient received chemotherapy with docetaxel and carboplatin. After three cycles of chemotherapy, the interval debulking surgery was attempted but resulted in suboptimal results. Because the bilateral ovaries were observed with a normal size and normal findings, we considered that the most likely diagnosis was primary peritoneal carcinosarcoma. After the additional chemotherapy and a 6-month observation period, the tumor relapsed. The patient received chemotherapy again, and the peritoneal carcinosarcoma was judged to be a platinum-sensitive tumor. Oral administration of olaparib was thus initiated. Although a dose reduction was needed due to anemia, olaparib was effective, and the patient could continue the drug for another 7 months. This is the first report of primary peritoneal carcinosarcoma treated with olaparib and shows that it could be a treatment option for platinum-sensitive tumors.2020年, Case reports in obstetrics and gynecology, 2020, 9106390 - 9106390, 英語, 国際誌
- © 2019, The Author(s). The identification of Human herpesvirus 6B (HHV-6B) epitopes that are recognized by T-cells could contribute to the development of potential vaccines and immunotherapies. Here, we identified CD4 + and H-2K d -restricted CD8 + T-cell epitopes on the glycoprotein Q1 of HHV-6B (BgQ1), which is a unique glycoprotein and essential for HHV-6B viral entry, by using in vivo electroporation with a plasmid DNA encoding BgQ1, overlapping peptides spanning the BgQ1 sequence, ELISPOT assay for quantification of gamma interferon (IFN-γ), and computer-based T-cell epitope prediction programs. The CD4 + and CD8 + T-cell epitopes identified in BALB/c mice in this study could be a good animal model system for use in the development of T-cell responses, inducing HHV-6B vaccines or immunotherapies.2019年03月, Scientific reports, 9(1) (1), 3911, 英語[査読有り]研究論文(学術雑誌)
- The aim of this nested case-control study was to evaluate clinical factors associated with the occurrence of congenital cytomegalovirus (CMV) infection in pregnant women with non-primary CMV infection. In a cohort study of CMV screening for 2193 pregnant women and their newborns, seven newborns with congenital CMV infection were identified among 1287 pregnant women with non-primary CMV infection that was defined as negative IgM and positive IgG with IgG avidity index >45%. In the 1287 women with non-primary CMV infection, clinical findings and complications were compared between pregnancies with and without congenital CMV infection. Clinical factors associated with the occurrence of congenital CMV infection were evaluated. The birth weight of newborns with congenital CMV infection was less than that of newborns without congenital infection (p < 0.05). Univariate logistic regression analyses demonstrated that threatened premature delivery (OR 10.6, 95%CI 2.0-55.0; p < 0.01) and multiple pregnancy (OR 7.1, 95%CI 1.4-37.4; p < 0.05) were associated with congenital infection. Multivariable logistic regression analyses demonstrated that threatened premature delivery (OR 8.4, 95%CI 1.5-48.1; p < 0.05) was a single risk factor for congenital CMV infection in pregnant women with non-primary CMV infection. This study revealed for the first time that threatened premature delivery was associated with the occurrence of congenital CMV infection in pregnant women with non-primary CMV infection, the pathophysiology of which may be closely associated with CMV reactivation during pregnancy.2018年09月, Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy, 24(9) (9), 702 - 706, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- 進行卵巣癌・原発性腹膜癌に対して術前化学療法(NAC)を行う際の主な診断方法として腹腔鏡下生検(LB)と体腔液の穿刺吸引細胞診がある。このうちLBは開腹手術に比べて低侵襲であり、診断の確実性からも有用な方法であるが、全身状態不良などの理由で腹腔鏡手術ですら躊躇する症例も少なくない。一方、穿刺吸引細胞診は全身状態不良な患者でも比較的安全に施行できるが、組織型の診断が困難という欠点がある。そこで、組織型の再現がしやすいcell block法(CB法)を穿刺吸引細胞診に取り入れている。今回、当院で2008〜2018年に進行卵巣癌もしくは原発性腹膜癌が疑われ治療された患者のうち、NAC施行時の診断目的にLBもしくはCB法を行い、根治手術時に病理診断が可能であった53例を対象とし、LB群(18例)とCB群(35例)に分け、「診断精度」「診断までに要した日数」「検査に伴う合併症」などについて群間比較した。結果、診断精度はLB群の全例で生検による診断と最終的な病理診断が一致していた。CB群では、漿液性癌の診断精度は高かったが、粘液性癌や癌肉腫では診断困難なケースが多かった。診断までに要した日数はLB群が平均8.9日、CB群が平均7.0日で、CB群ほうが有意に短かった。合併症の発生率に有意差は認めなかった。「産婦人科の進歩」編集室, 2020年08月, 産婦人科の進歩, 72(3) (3), 211 - 215, 日本語

- 47歳女。39歳時に腹腔鏡下子宮筋腫核出術、40歳時に甲状腺乳頭癌に対して甲状腺摘出術の既往があった。無月経、不正性器出血で受診した際に、骨盤内から後腹膜腔へ発達する巨大な腫瘍を指摘された。PET-CTでは腫瘍部位にFDGの有意な集積を認めず、有茎性漿膜下筋腫を疑った。原発不明腫瘍の診断で手術を施行した。病理組織では、腹腔鏡下子宮筋腫核出術の既往があることから、腹腔鏡下筋腫核出術後に発生した医原性parasitic myomaと推察した。当時の手術記録を取り寄せたところ、子宮後壁頸部近くの97mm大の筋腫を核出後、モルセレーターを使用し体外に摘出していた。その際の残存筋腫が栄養血管を獲得しながら発育し、後腹膜腔にまで達する巨大なparasitic myomaとなったと推測された。腫瘍および子宮頸部・体部細胞診において悪性所見は認めず、不正性器出血に関しては閉経周辺期の機能性子宮出血と考えられた。「産婦人科の進歩」編集室, 2014年10月, 産婦人科の進歩, 66(4) (4), 361 - 366, 日本語
