Case report: Physical findings, physical therapy practice, and characteristics of disability of activities of daily living caused by obturator nerve palsy after neurotmesis.

The obturator nerve originates from the lumbar plexus and innervates sensation in the thigh and movement of the adductor muscle group of the hip. Reports on physical therapy for patients with obturator nerve injuries have been limited due to insufficient injuries, and there have been no reports on rehabilitation after neurotmesis. Furthermore, there are no reports on the status of activities of daily living (ADL) and details of physical therapy in patients with paralysis of the adductor muscle group. In this study, we reported on a patient with adductor paralysis due to obturator neurotmesis, including the clinical symptoms, characteristics of ADL impairment, and effective movement instruction. The patient is a woman in her 40's who underwent laparoscopic total hysterectomy, bilateral adnexectomy, and pelvic lymph node dissection for uterine cancer (grade-2 endometrial carcinoma). During pelvic lymph node dissection, she developed an obturator nerve injury. She underwent nerve grafting during the same surgery by the microsurgeon. Donor nerve was the ipsilateral sural nerve with a 3-cm graft length. Due to obturator nerve palsy, postoperative manual muscle test results were as follows: adductor magnus muscle, 1; pectineus muscle, 1; adductor longs muscle, 0; adductor brevis muscle, 0; and gracilis muscle, 0. On postoperative day 6, the patient could independently perform ADL; however, she was at risk of falling toward the affected side when putting on and taking off her shoes while standing on the affected leg. The patient was discharged on postoperative day 8. Through this case, we clarified the ADL impairment of a patient with adductor muscle palsy following obturator neurotmesis, and motion instruction was effective as physical therapy for this disability. This case suggests that movement instruction is important for acute rehabilitation therapy for patients with hip adductor muscle group with obturator neurotmesis.

Comparison of Surgical Results and Postoperative Recurrence Rates by Laparoscopic Sacrocolpopexy with Other Surgical Procedures for Managing Pelvic Organ Prolapse.

OBJECTIVES: Pelvic organ prolapse (POP) is relatively high for a gynecologic disease. Laparoscopic sacrocolpopexy (LSC) is currently the main surgical option for managing POP. The priority of the surgical treatment is preventing recurrence after the surgery. We presented the surgical outcome and recurrence rate of LSC and compared the data of LSC with that of other surgical procedures for managing POP to examine the effectiveness of LSC over other them. MATERIALS AND METHODS: We compared the results of 138 cases of LSC with other conventional procedures, namely 30 cases of total vaginal hysterectomy (TVH) combined with colporrhaphy anterior and posterior, 66 cases of the Manchester operation, and 68 cases of colpocleisis. We compared the age, body mass index, operative time, blood loss volume, postoperative hospital stay duration, rate of complications, recurrence rate, reoperation rate, and the cumulative recurrence rate after 10 years. RESULTS: The complication rate of LSC, TVH, the Manchester operation, and colpocleisis was 2.2%, 3.3%, 3.0%, and 4.4%; the recurrence rate 2.8%, 3.5%, 4.5%, and 8.7%; and the cumulative recurrence rate after 10 years 3.7%, 4.6%, 8.8%, and 18.2%. There was no significant difference between LSC and the other three groups. CONCLUSION: LSC seems to be an effective surgical option that requires a higher skill level than other surgical methods and has a longer operative time, lesser operative invasion, and a lower long-term recurrence rate. We will actively recommend LSC to those when appropriate.

Ovarian cyst elevation using a metreurynter for laparoscopic cystectomy of a benign ovarian cyst during pregnancy.

BACKGROUND: A uterine manipulator cannot be used to elevate the ovary in benign ovarian surgery during pregnancy. This report describes our method of elevation of the ovary using a metreurynter with the success rate of the procedure and a comparison of surgical results and pregnancy outcomes between the successful and unsuccessful cases. METHODS: Between August 2003 and February 2020, 11 pregnant patients with a tumor found sunk in the Cul-de-sac underwent laparoscopic cystectomy for a benign ovarian cyst with a metreurynter. The surgical results, success and failure of the elevation by a metreurynter, pregnancy outcomes, and fetal status at delivery were evaluated. RESULTS: Elevation of ovarian tumors with a metreurynter was successful in nine cases. However, it was unsuccessful in the remaining two cases wherein the ovary was lifted with forceps while the uterus was in a compressed state. The operative time was also longer in these cases. The pregnancy prognosis, however, was good for both, successful and unsuccessful cases. CONCLUSIONS: The metreurynter is an inexpensive and practical obstetric device, and its optimal use allows the performance of a procedure with minimal burden on a pregnant uterus. Therefore, we recommend the appropriate use of this method to enable effective laparoscopic cystectomy of ovarian tumors during pregnancy.

Changes in the gene mutation profiles of circulating tumor DNA detected using CAPP-Seq in neoadjuvant chemotherapy-treated advanced ovarian cancer.

Cancer Personalized Profiling by deep Sequencing (CAPP-Seq) is a novel ultrasensitive next-generation sequencing-based approach that is used to detect circulating tumor DNA (ctDNA). The aim of the present study was to compare the gene mutation profiles and blood tumor mutation burden (bTMB) measured between pre- and post-neoadjuvant chemotherapy (NAC), utilizing CAPP-seq for plasma ctDNA in patients with advanced ovarian cancer. The current study included 10 patients (6 NAC-sensitive and 4 NAC-resistant) clinically diagnosed as having stage III or IV ovarian cancer and were administered NAC between May 2017 and February 2019. The plasma ctDNA samples were collected at pre- and post-NAC, and comprehensive gene mutation analysis was performed using CAPP-seq. In 5 out of 6 NAC-sensitive cases, the variant allele frequency (VAF) of non-synonymous somatic mutations decreased following NAC. In 2 out of the 4 NAC-resistant cases, the VAF of non-synonymous somatic mutations increased, and new somatic mutations emerged following NAC. In regard to TP53 mutation, the rate of TP53 mutation in the NAC-resistant cases was significantly higher compared with NAC-sensitive cases. Finally, the bTMB decreased significantly after NAC treatment in the NAC-sensitive cases, even though there were no significant differences in the pretreatment bTMB levels between the NAC-sensitive and NAC-resistant cases. These results indicated that gene mutation can be profiled and monitored using liquid biopsy-based CAPP-Seq in patients with advanced ovarian cancer with NAC treatment, and TP53 mutation in the ctDNA and bTMB may be novel biomarkers that can be used for patient monitoring during NAC treatment.

Laparoscopically resected Castleman's disease in the pelvic retroperitoneum: A case report.

Castleman's disease is a rare benign disorder of unknown etiology characterized by proliferation of lymphoid tissues. Castleman's disease arising from pelvic retroperitoneum is clinically rare. The present case report describes a rare case of laparoscopically resected Castleman's disease in the pelvic retroperitoneum associated with benign ovarian cyst. A 47-year-old woman, gravida 5, para 3, was referred to to the Department of Obstetrics and Gynecology of Wakayama Medical University with a suspected pelvic tumor. Magnetic resonance imaging revealed that the solid tumor was localized in the retroperitoneal space at the right side of the pelvis. The patient underwent laparoscopic surgery for the resection of the pelvic retroperitoneal tumor, with complete tumor resection. Postoperative pathological examination established the diagnosis of Castleman's disease. The postoperative course was uneventful, with no evidence of local recurrence or systemic disease 6 months after diagnosis.

Laparoscopic Repair for Vesicoperitoneal Fistula with Vesicouterine Abscess.

Vesicoperitoneal fistula (VPF) is a rare form of urogenital fistulas. It is usually associated with an accidental trauma or iatrogenic injury including postoperative complications. Although it is difficult to heal the fistula conservatively, a laparoscopic repair is one of the effective methods. We report a case of VPF with vesicouterine abscess and repaired it laparoscopically. The transvaginal sonography showed the vesicouterine abscess, and a cystoscopy revealed a fistula between the vesicouterine abscess and the bladder. The abovementioned condition was confirmed at the time of laparoscopic surgery, and the fistula tract was closed laparoscopically.

Liquid biopsy-based comprehensive gene mutation profiling for gynecological cancer using CAncer Personalized Profiling by deep Sequencing.

Liquid biopsies of circulating tumor DNA (ctDNA) have recently been used as a non-invasive diagnostic tool for detecting tumor-specific mutations. We present a study of ctDNA liquid biopsies in gynecological cancer using an ultrasensitive next-generation sequencing-based method for ctDNA detection named CAncer Personalized Profiling by deep Sequencing (CAPP-Seq). We performed CAPP-Seq with plasma-ctDNA obtained from 16 patients with gynecological cancer. In all cases, at least one non-synonymous somatic mutation was detected in the ctDNA. In the pre-treatment ctDNA, 4 of 16, 4/16, 5/16, 2/16, 2/16, and 2/16 patients had TP53, KRAS, APC, PIK3CA, BRCA1, and EGFR mutations, respectively. MET gene copy-number gains were detected in the ctDNA of 2 of 16 patients, and FISH analysis of the paired tumor samples confirmed these results. In 2 neoadjuvant chemotherapy-treated ovarian cancer patients, the changes in gene mutation patterns were associated with the treatment response. These findings suggest that CAPP-Seq-based liquid biopsies can be used for the genetic characterization of independent gynecological cancers with high frequency, and might be clinically useful for non-invasive tumor genotyping and therapeutic response monitoring.

Short term outcomes of helical tomotherapy during concurrent chemoradiotherapy for advanced cervical cancer.

The aim of the present study was to clarify the feasibility and efficacy of helical tomotherapy during concurrent chemoradiotherapy for treating cervical cancer. The medical records of 13 patients who underwent oncurrent chemoradiotherapy using helical tomotherapy for cervical cancer at Wakayama Medical University Hospital between 2013 and 2015 were retrospectively reviewed. A total of 15 patients who underwent oncurrent chemoradiotherapy using conventional radiotherapy (CRT) between 2008 and 2013 at our institution were also examined for comparison. The median age of patients treated with helical tomotherapy was 60 (range, 35-71), and the median age of patients treated with CRT was 57 (range, 43-77). The median follow-up period was 27 months (range, 3-46) in the tomotherapy group and 35 months (range, 7-88) in the CRT group. The frequency of G3/4 thrombocytopenia in the tomotherapy group was significantly higher than that in the CRT group (P=0.049). However, the platelet count spontaneously recovered without transfusion. There were no significant differences between the groups in terms of frequency of G3/4 neutropenia, diarrhea or late intestine injury. The rate of complete response in the tomotherapy group and the CRT group was 84.6 and 73.3%, respectively, and there was no significant difference in the response rate between the groups. There were no significant differences in the progression-free survival or progression-free rate in the irradiation field between the groups. Adverse events from concurrent chemoradiotherapy using helical tomotherapy were acceptable and clinically controllable. The present results suggest that helical tomotherapy is efficient during concurrent chemoradiotherapy for treatment of advanced cervical cancer.

Programmed cell death ligand 1 disruption by clustered regularly interspaced short palindromic repeats/Cas9-genome editing promotes antitumor immunity and suppresses ovarian cancer progression.

Programmed cell death ligand 1 (PD-L1) on tumor cells suppresses anti-tumor immunity and has an unfavorable prognostic impact in ovarian cancer patients. We herein report the pathophysiological and therapeutic impacts of PD-L1 disruption in ovarian cancer. PD-L1 was genetically disrupted in the murine ovarian cancer cell line ID8 using clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9-mediated genome editing. PD-L1 knockout (KO) and control ovarian cancer cells were intraperitoneally inoculated into syngeneic mice, and survival and tumor dissemination were evaluated. Survival times were significantly longer in the PD-L1-KO ID8-inoculated groups than in their control groups, and its therapeutic benefit was enhanced in combination with the cisplatin treatment. Tumor weights and ascites volumes were significantly lower in the PD-L1-KO ID8 groups than in their control groups. Immunohistochemical and immunofluorescence analyses showed that intratumoral CD4+ T cells, CD8+ T cells, NK cells and CD11c+ M1 macrophages were significantly increased, whereas regulatory T cells were significantly decreased in the PD-L1-KO ID8 groups compared with those in their control groups. The intratumoral mRNA expression of interferon-γ, tumor-necrosis factor-α, interleukin (IL)-2, IL-12a, CXCL9 and CXCL10 was significantly stronger, while that of IL-10, vascular endothelial growth factor, CXCL1 and CXCL2 was significantly weaker in the PD-L1-KO ID8 groups. These results indicate that CRISPR/Cas9-mediated PD-L1 disruption on tumor cells promotes anti-tumor immunity by increasing tumor-infiltrating lymphocytes and modulating cytokine/chemokine profiles within the tumor microenvironment, thereby suppressing ovarian cancer progression. These results suggest that PD-L1-targeted therapy by genome editing may be a novel therapeutic strategy for ovarian cancer.

Live birth following laparoscopic fertility-sparing surgery for papillary thyroid carcinoma arising from mature ovarian cystic teratoma: A case report.

Papillary thyroid carcinoma arising from ovarian mature cystic teratoma is clinically rare. We herein present a case of live birth following two laparoscopic surgeries for papillary thyroid carcinoma arising in a mature ovarian cystic teratoma. A 30-year-old female patient, gravida 1 para 1, was treated by laparoscopic bilateral ovarian cystectomy for suspicion of bilateral mature cystic teratoma. The diagnosis of papillary thyroid carcinoma arising from right ovarian mature cystic teratoma was established based on postoperative pathological examination of the tumor. Such rare neoplasms may be difficult to diagnose preoperatively based on radiological examinations alone. The patient underwent laparoscopic fertility-preserving unilateral (right) salpingo-oophorectomy. Following an extensive discussion with the patient and her family, appropriate informed consent was obtained for the treatment option and the patient and her family chose to preserve her fertility. She could have a baby following the treatment and no evidence of disease for 6 years. Gynecologists should be aware of the possibility of such rare cases, and the available surgical interventions should be fully discussed with patients who wish to preserve their fertility. Laparoscopic fertility-sparing surgery may be a feasible option when encountering such a rare condition.

A comprehensive gene mutation analysis of liquid biopsy samples from patients with metastatic colorectal cancer to the ovary: A case report.

Liquid biopsies of circulating tumor DNA (ctDNA) can detect molecular alterations, including tumor-specific mutations, and have recently been used as a non-invasive diagnostic, prognostic, and predictive tool. However, this technique is not commonly used in the gynecological field. Gene mutation profiling of liquid biopsy samples was performed using CAncer Personalized Profiling by deep Sequencing (CAPP-Seq), a novel next-generation sequencing-based approach to ultrasensitive ctDNA detection, in order to make it possible to molecularly diagnose metastatic colorectal cancer to the ovary. Liquid biopsy (plasma) samples and formalin-fixed paraffin-embedded tumor samples were obtained from two patients with ovarian tumors, who had a history of surgery for colorectal cancer, and comprehensive gene mutation profiling was conducted using CAPP-Seq. In patient 1, mutations were identified in the same three regions in both the ovarian tumor and preoperative plasma sample (in the KRAS G13D, APC E1306*, and TP53 H193Y genes). In patient 2, mutation was identified in the same one region in all the primary colorectal tumor, the ovarian tumor, and preoperative plasma sample (in APC R216* gene). These mutations are well-known genetic signatures of colorectal cancer, suggesting that the ovarian tumor was metastatic. Tthe gene mutation patterns of colorectal cancer were examined by subjecting liquid biopsy samples from patients with suspected metastatic ovarian tumors to CAPP-Seq. Gene mutation profiling of liquid biopsy samples can contribute to the preoperative differential diagnosis of metastatic ovarian cancer and its subsequent personalized treatment.

Prevention of lipopolysaccharide-induced preterm labor by the lack of CX3CL1-CX3CR1 interaction in mice.

Preterm labor (PTL) is the most common cause of neonatal death and long-term adverse outcome. The pharmacological agents for PTL prevention are palliative and frequently fail to prevent PTL and improve neonatal outcome. It is essential to fully understand the molecular mechanisms of PTL in order to develop novel therapeutic methods against PTL. Several lines of evidence indicate some chemokines are expressed in gestational tissues during labor or PTL. To reveal the pathophysiological roles of the CX3CL1-CX3CR1 axis in PTL, we performed present study using LPS-induced PTL mice model in CX3CR1-deficient (Cx3cr1-/-) mice. We indicated that PTL was suppressed in Cx3cr1-/- mice and immunoneutralization of CX3CL1 in WT mice. From immunohistochemical and the gene expression analyses, the CX3CL1-CX3CR1 axis has detrimental roles in PTL through intrauterine recruitment of macrophages and the enhancement of macrophage-derived inflammatory mediators. Thus, the CX3CL1-CX3CR1 axis may be a good molecular target for preventing PTL.

Levels of serum-circulating angiogenic factors within 1 week prior to delivery are closely related to conditions of pregnant women with pre-eclampsia, gestational hypertension, and/or fetal growth restriction.

AIM: We aimed to investigate maternal serum angiogenic marker profiles within 1 week prior to delivery in cases of gestational hypertension (GH), pre-eclampsia (PE), and/or fetal growth restriction (FGR) with different clinical conditions. METHODS: We enrolled 165 women with singleton pregnancy. The participants were classified based on three characteristics: (i) proteinuria (GH and PE); (ii) FGR (PE with FGR [PE + FGR], PE alone, and FGR alone); and (iii) onset (early onset PE [EO PE] and late-onset PE [LO PE]). All sera were obtained within 1 week prior to delivery, and soluble fms-like tyrosine kinase 1 (sFlt-1), soluble endoglin (sEng), and placental growth factor (PlGF) were measured with enzyme-linked immunosorbent assay. RESULTS: (i) In PE, a significantly increased sFlt-1, sEng, and sFlt-1 to PlGF ratio (sFlt-1/PlGF) and significantly decreased PlGF were observed compared with GH and Term control, whereas in GH, only sFlt-1/PlGF was significantly higher than Term control. (ii) In PE + FGR, similar changes were more markedly shown compared with PE alone. The FGR alone group exhibited similar tendencies as PE, although significant differences were found in PlGF and sEng levels. (iii) In EO PE, significant changes were observed in all factors compared with LO PE or Term control, while no significant change in PlGF levels was observed between LO PE and Term control. CONCLUSION: We demonstrated that the levels of circulating angiogenic factors just before delivery are correlated with the severity of hypertensive disorders of pregnancy and FGR. Profiling these specific markers may contribute to better understanding of the clinical conditions in individual patients and their pathogenesis.

Rapidly progressing large-cell neuroendocrine carcinoma arising from the uterine corpus: A case report and review of the literature.

Large-cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine tumor. LCNECs arising from the genital organs are highly malignant and rare, with <20 cases of LCNEC developing from the uterine endometrium reported to date. We herein present the case of a patient with LCNEC of the endometrium. The patient was a 52-year-old woman, who exhibited lower abdominal pain and rapid uterine enlargement during outpatient treatment for uterine myoma. The endometrial biopsy suggested a diagnosis of poorly differentiated carcinoma or carcinosarcoma. Based on magnetic resonance imaging and positron emission tomography/computed tomography, endometrial stromal sarcoma was suspected. The serum lactate dehydrogenase level was abnormally high. Due to the suspicion of stage IIIC malignant tumor of the uterine corpus, surgery was performed. The pathological diagnosis was stage IIIC2 LCNEC of the endometrium. Recurrence occurred in the vaginal stump, and concurrent chemoradiotherapy (CCRT) was initiated 1 month after the surgery. The residual lesions markedly shrank, but metastasis to the upper abdominal region and cervix subsequently developed. CCRT was attempted, but the associated adverse effects were severe and was switched to palliative treatment. The patient eventually succumbed to the disease 309 days after surgery.

Prognostic impact of primary tumor SUVmax on preoperative 18F-fluoro-2-deoxy-D-glucose positron emission tomography and computed tomography in endometrial cancer and uterine carcinosarcoma.

The objective of the present study was to investigate the usefulness of the maximum standardized uptake value (SUVmax) of the primary tumor on preoperative 18F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography and computed tomography (PET/CT) as a prognostic indicator in patients with endometrial neoplasms. A total of 75 patients with endometrial cancer or uterine carcinosarcoma who underwent surgical treatment were included in the present study. All patients underwent preoperative PET/CT, and the correlation between the SUVmax of the primary tumor and clinical outcomes was analyzed. The SUVmax was significantly higher in patients with stage II/III disease, a histology of grade 3 endometrioid adenocarcinoma and carcinosarcoma, a positive lymph node (LN) status, positive lymph-vascular space involvement (LVSI), and deep (≥1/2) myometrial invasion. Receiver operating characteristic curve analysis revealed that the optimal cut-off values of SUVmax for predicting a positive LN, LVSI and deep myometrial invasion were 7.49, 6.45 and 6.45, respectively. The overall survival (OS) and progression-free survival (PFS) of patients with a high SUVmax were significantly lower compared with those of patients with a low SUVmax using the cut-off value of 7.30. However, no significant difference was observed in the OS or PFS between the high and low SUVmax groups when analyzed in carcinosarcoma patients alone. Finally, multivariate analyses demonstrated that the SUVmax of the primary tumor was an independent prognostic factor for impaired PFS in 55 endometrioid adenocarcinoma patients; however, not in all patients, including those with carcinosarcoma. The present findings demonstrated that the SUVmax of the primary tumor may be a useful biomarker for predicting clinical outcomes of patients with endometrial cancer, although its prognostic impact appears to be limited in patients with uterine carcinosarcoma.

Primary tumor SUVmax on preoperative FDG-PET/CT is a prognostic indicator in stage IA2-IIB cervical cancer patients treated with radical hysterectomy.

The objective of the present study was to investigate the prognostic value of 18F-fluoro-2-deoxy-D-glucose (FDG) uptake by primary tumors on positron emission tomography/computed tomography (PET/CT) in surgically resectable cervical cancer. A total of 59 patients with stage IA2-IIB cervical cancer who underwent preoperative FDG-PET/CT, followed by radical hysterectomy and lymphadenectomy, were included in the study. The maximum standardized uptake value (SUVmax) of the primary tumor was measured, and the association between the SUVmax and clinicopathological factors or patient outcomes was analyzed. The SUVmax was significantly higher in patients with an advanced stage, lymph node metastasis, lymph-vascular space involvement and large tumors. The overall survival (OS) and progression-free survival (PFS) of patients with a high SUVmax were significantly lower compared with patients with a low SUVmax, using an optimal cut-off value of 7.36 for OS and 5.59 for PFS obtained from receiver operating characteristic curve analysis. Similarly, OS and PFS in patients with a high SUVmax were significantly lower in 39 patients with stage IB using a cut-off value of 7.90 and 6.69 for OS and PFS, respectively. Finally, multivariate analyses showed that the SUVmax of the primary tumor was an independent prognostic factor for impaired PFS in all patients and those with stage IB alone. These findings demonstrated that a high SUVmax on preoperative PET/CT was correlated with unfavorable clinical outcomes in patients receiving radical hysterectomy, suggesting that the SUVmax of the primary tumor may be a prognostic indicator for surgically-treated, early-stage invasive cervical cancer.

Clinicopathologic Factors of Cervical Adenocarcinoma Stages IB to IIB.

OBJECTIVE: The aim of this study was to clarify the clinicopathologic factors of stages IB to IIB cervical adenocarcinoma. METHODS: Several clinicopathologic factors were compared between 35 patients who underwent radical hysterectomy and pelvic lymphadenectomy due to cervical adenocarcinoma stages IB to IIB and 77 patients with squamous cell carcinoma (SCC). RESULTS: In patients with adenocarcinoma, univariate analysis demonstrated that International Federation of Gynecology and Obstetrics stage, tumor size, and lymphovascular space invasion were significantly associated with progression-free survival (PFS), whereas FIGO stage, lymphovascular space invasion, and lymph node metastasis were significantly associated with overall survival (OS). However, multivariate analysis revealed that FIGO stage was the only significant factor for PFS in patients with adenocarcinoma. In patients with SCC, univariate analysis demonstrated that FIGO stage and lymph node metastasis were significantly associated with PFS, whereas FIGO stage, lymphovascular space invasion, and lymph node metastasis were significantly associated with OS. Multivariate analysis revealed that lymph node metastasis was the only significant factor for PFS and OS in patients with SCC. In 26 patients who were positive for high-risk human papillomavirus (HPV), including both adenocarcinoma and SCC patients, univariate and multivariate analyses revealed that HPV18 was significantly associated with poorer PFS compared with non-HPV18. There was a significant difference in distribution of HPV genotype between adenocarcinoma and SCC. CONCLUSIONS: Careful treatment may be necessary for the patients with lymphovascular space invasion in early-stage cervical adenocarcinoma. The presence of HPV18 may have an influence on the prognosis of early-stage cervical carcinoma.

Vaginal carcinoma in a young woman who underwent fertility-sparing treatment involving chemotherapy and conservative surgery.

Vaginal carcinoma is a rare gynecological malignancy that is usually treated by radiation therapy and/or surgery combined with chemotherapy. Here, we report a case of invasive vaginal carcinoma in a young woman who underwent fertility-sparing treatment involving neoadjuvant chemotherapy and conservative surgery. A 36-year-old non-parous woman had a solid tumor in the vagina. Positron emission tomography/computed tomography showed a tumor in the vagina with high FDG uptake (SUV = 17.33) but no metastatic lesions. The patient was diagnosed with vaginal squamous cell carcinoma, FIGO stage I, T1N0M0. Because she wished to retain her fertility, neoadjuvant chemotherapy consisting of irinotecan hydrochloride and nedaplatin was initiated. After four courses of chemotherapy, partial vaginectomy was carried out and the pathological diagnosis of the residual lesion was VAIN 3. Following two further courses of the same chemotherapy, she obtained complete response, and has shown no evidence of disease for 14 months.
