RESUMO
This study evaluated the influence of positive peritoneal cytology (PPC) on the prognosis of patients with stage IA endometrial cancer, and the usefulness of adjuvant chemotherapy in their treatment. We retrospectively analyzed the data of patients with stage IA endometrial cancer admitted in our hospital between 2005 and 2015. Among 989 patients who underwent peritoneal cytology, 135 (13.7%) had PPC. Multivariate analysis extracted several independent risk factors for recurrence in stage IA patients, including those with PPC. Adjuvant chemotherapy did not cause a significant difference in the 5-year relapse-free survival rate in patients with PPC (p = 0.78). Similarly, the 5-year recurrence-free survival rate with or without chemotherapy was not different among type II cancer patients (p = 0.11). However, the baseline risk of 5-year relapse-free survival without chemotherapy in patients with PPC and type II was very low (66.7%). While PPC was an independent risk factor for recurrence in stage IA endometrial cancer, adjuvant chemotherapy did not influence the survival rate in patients with PPC. While it is controversial whether adjuvant chemotherapy should be administered in stage IA uterine cancer with only PPC as a prognostic factor, it should be considered for early-stage patients who have multiple risk factors for recurrence.

AIM: It is uncertain whether curative surgical treatment or a less radical surgery with adjuvant treatment should be provided to preserve function in patients with vulvar squamous cell carcinoma (SCC) that is adjacent to the urethra, anus, and vagina. The aim of this study was to investigate the surgical margin in patients with vulvar SCC with regard to local recurrence and overall survival. METHODS: Thirty-four patients were identified as having a diagnosis of vulvar SCC without distant metastasis. They had been treated surgically with curative intent at the Cancer Institute Hospital. Clinical data were analyzed retrospectively. RESULTS: Rates of 5-year local recurrence-free survival among patients with positive, <3-mm, <5-mm, <8-mm, and ≥8-mm surgical margins were 32%, 30.3%, 42.5%, 55.5%, and 73%, respectively. Rates of 5-year overall survival of patients with positive, <3-mm, <5-mm, <8-mm, and ≥8-mm surgical margins were 15.5%, 53.8%, 58.8%, 67.6%, and 83.3%, respectively. In the multivariable analysis, a tumor size of more than 2-cm (hazard ratio [HR] = 17.7, 95% confidence interval [CI] = 1.39-226) and a positive surgical margin (HR = 0.0092, 95% CI = 0.011-0.53) were risk factors for local recurrence, and a lymph node involvement (HR = 1.41, 95% CI = 0.31-6.43) and a positive surgical margin (HR = 0.0046, 95% CI = 0.011-0.53) were significant risk factors for overall mortality. CONCLUSIONS: To improve the prognosis, thorough resection with an adequate surgical margin is needed. But narrow surgical margin may be acceptable, particularly to preserve the function of adjacent organs.

BACKGROUND: To clarify the clinical as well as pathological outcomes in Japanese women with germline pathogenic BRCA1/2 variants who underwent risk-reducing salpingo-oophorectomy (RRSO). METHODS: This prospective study examined the rate of occult cancer and primary peritoneal cancer after RRSO at our institution in the period from 2011 to 2020. Clinical records of genetically confirmed patients with germline pathogenic BRCA1/2 variants who desired to undergo RRSO were reviewed. Specimens obtained during RRSO were pathologically diagnosed as per SEE-FIM protocol. All the participants underwent magnetic resonance imaging (MRI) about 1 month preoperatively. RESULTS: One hundred and seventeen women underwent RRSO during this period. Of these, the numbers of women with germline pathogenic BRCA1 and BRCA2 variants were 72 and 45, respectively. The mean observational time after RRSO was 35.8 months. Despite negative preoperative screening results, three (2.6%) serous tubal intraepithelial carcinoma and three (2.6%) invasive carcinomas were identified. Of the three invasive carcinomas cases, two were International Federation of Gynecology and Obstetrics (FIGO) stage I primary fallopian tube cancer, and the third case was double cancer (ovarian cancer and fallopian tube cancer) with FIGO stage IC3. CONCLUSIONS: The rate of occult neoplasms was similar to those reported by studies performed in other countries. Although women with occult cancer were diagnosed with FIGO stage I, the MRI performed 1 month preoperatively did not show any such malignant findings. Thus, RRSO is the only promising method that can improve the prognosis in women with germline pathogenic BRCA1/2 variants.

BACKGROUND: The aim of this study was to investigate the safety and clinical usefulness of early oral feeding (EOF) after rectosigmoid resection with anastomosis for the treatment of primary ovarian cancer. METHODS: We performed a retrospective review of all consecutive patients who had undergone rectosigmoid resection with anastomosis for primary ovarian, tubal, or peritoneal cancer between April 2012 and March 2019 in a single institution. Patient-related, disease-related, and surgery-related data including the incidence of anastomotic leakage and postoperative hospital stay were collected. EOF was introduced as a postoperative oral feeding protocol in September 2016. Before the introduction of EOF, conventional oral feeding (COF) had been used. RESULTS: Two hundred and one patients who underwent rectosigmoid resection with anastomosis, comprised of 95 patients in the COF group and 106 patients in the EOF group, were included in this study. The median number of postoperative days until the start of diet intake was 5 (range 2-8) in the COF group and 2 (range 2-8) in the EOF group (P < 0.001). Postoperative morbidity was equivalent between the groups. The incidence of anastomotic leakage was similar (1%) in both groups. The median length of the postoperative hospital stay was reduced by 6 days for the EOF group: 17 (range 9-67) days for the COF group versus 11 (8-49) days for the EOF group (P < 0.001). CONCLUSION: EOF provides a significant reduction in the length of the postoperative hospital stay without an increased complication risk after rectosigmoid resection with anastomosis as a part of cytoreductive surgery for primary ovarian cancer.

After pelvic lymphadenectomy (PLA), pelvic vessels, nerve, and ureter are skeletonized. Internal hernias beneath the skeletonized pelvic structure following pelvic lymphadenectomy (IBSPP) are a rare complication following PLA. To the best of our knowledge, only 12 IBSPP cases have been reported and clinical details on such hernias remain unknown. The aim of the study was to investigate the incident and etiology of IBSPP. 1313 patients who underwent open or laparoscopic pelvic lymphadenectomy were identified from our database. A retrospective review was performed. Mean follow-up period was 33.9 months. A total of 12 patients had IBSPP. Multivariate analysis of laparoscopic surgeries group as compared to open surgeries group, para-aortic lymphadenectomy rate, number of dissected lymph nodes by PLA, antiadhesive material use rate, and blood loss were lower in laparoscopic surgeries group: odd ratio (OR) = 0.13 [95% confidence interval (CI) 0.08-0.19], and OR = 0.70 [95% CI 0.50-0.99], OR = 0.17 [95% CI 0.10-0.28], OR = 0.93 [95% CI 0.92-0.94]. However, no significant difference was observed in the incidence of IBSPP between laparoscopic surgery (1.0%) and open surgery (0.8%). All IBSPP occurred in the right pelvic space. These findings may contribute to the development of prevention methods for this disease.

OBJECTIVE: Surgery is the only treatment for cervical cancer recurrence in a previously irradiated field. Pelvic exenteration (PE) and laterally extended endopelvic resection (LEER) are indicated for select patients; however, morbidity and mortality rates remain high, and new treatment modalities are required. Laparoscopy optimizes visualization and allows meticulous dissection while also reducing intraoperative blood loss and postoperative complications without worsening the outcomes. We aimed to clarify the feasibility and outcomes of laparoscopic PE and LEER for previously irradiated recurrent cervical cancer. METHODS: We prospectively investigated the outcomes of laparoscopic PE and LEER in 28 patients with recurrent cervical carcinoma after radiotherapy. RESULTS: Seventeen laparoscopic PEs for central recurrences and 11 laparoscopic LEERs for lateral recurrences were performed. The median operation time and blood loss were 454mins and 285 mL in the PE group, and 562mins and 325 mL in the LEER group, respectively, with no conversions to laparotomy. R0 resection was achieved in all patients in the PE group and 73% in the LEER group. The morbidity and mortality rates were 41% and 0% in PE group, and 55% and 0% in LEER group, respectively. The 2-year disease-free survival and overall survival were 68.9% and 76% in the PE group, and 27.3% and 29.6% in the LEER group, respectively. CONCLUSION: Laparoscopic PE is feasible for previously irradiated central recurrent cervical cancer and has acceptable outcomes. Laparoscopic LEER is also feasible for lateral recurrence, but oncologic outcome may be modest in this limited preliminary study. Further studies using a larger sample size with a longer follow-up period is warranted to determine the indications for laparoscopic LEER.

BACKGROUND/AIM: Chemotherapy with additional bevacizumab is the standard treatment for primary and recurrent ovarian cancer. We aimed to investigate the clinical utility and safety of bevacizumab when used in combination with chemotherapy after disease progression. PATIENTS AND METHODS: This retrospective, observational study recruited patients treated for recurrent ovarian cancer from 2014 to 2016. We evaluated the effects of bevacizumab with chemotherapy in patients whose disease had progressed following treatment with bevacizumab. We assessed progression-free survival and adverse events. RESULTS: Thirty-three patients received post-progression treatment with bevacizumab. The median progression-free survival was 8.7 months (95% confidence interval=5.5-11). The progression-free survival was compared pre- and post-progression treatment, and was longer in platinum-resistant than platinum-sensitive cases after treatment (p=0.06). The most common non-hematological toxicity was proteinuria. The incidence of serious adverse events was low. CONCLUSION: Continuous administration of bevacizumab may be beneficial for ovarian cancer patients after disease progression.

OBJECTIVE: Definitive radiation therapy (RT), using external beam RT and/or brachytherapy, is a standard treatment option for primary vaginal carcinoma. However, this treatment has poor prognosis when applied to vaginal nonsquamous cell carcinoma (non-SCC). We aimed to clarify treatment outcome and surgical safety in early-stage primary vaginal non-SCC. METHODS: After receiving approval from the institutional review board, we retrospectively reviewed the clinical records and pathological samples of patients treated at our hospital between 1991 and 2018. Among 49 patients with primary vaginal carcinoma, 12 with histologically confirmed early-stage primary vaginal non-SCC were included in this study. RESULTS: In total, 40% of patients with primary vaginal carcinoma treated at our hospital had primary vaginal non-SCC. The average observation time was 34 months (median 53.3 months). Three patients had local recurrence: 2 in pelvic lymph nodes and 1 in the vagina. Furthermore, 2 patients died of their disease. Five-year local control rate of stage I and stage II non-SCC was 75% and 100%, respectively. Disease-specific survival rate of stage I and stage II non-SCC was 81.8% and 100%, respectively. No major morbidity was observed. Three patients required allogeneic blood transfusion, whereas 1 underwent autotransfusion. None of the 12 patients were discharged with self-catheterization. CONCLUSION: Five-year local control and disease-specific survival rates of patients surgically treated for vaginal non-SCC were favorable. Therefore, surgery could be a safe and reasonable option for early-stage primary vaginal non-SCC.

OBJECTIVE: To examine the association between surgical volume and survival of women with early-stage cervical cancer who underwent radical hysterectomy. METHODS: This is a nationwide multicenter retrospective study examining consecutive women with clinical stage IB1-IIB cervical cancer who underwent radical hysterectomy and pelvic lymphadenectomy from 2004 to 2008 (N=5,964). The surgical volume per site over the 5-year period was defined as low-volume (fewer than 32 surgeries, 46 [39.7%] institutions, n=649 [10.9%]), mid-volume (32-104 surgeries, 60 [51.7%] institutions, n=3,662 [61.4%]), and high-volume (105 surgeries or more, 10 [8.6%] institutions, n=1,653 [27.7%]). Surgical volume-specific survival was examined with multivariable analysis and propensity score matching. RESULTS: The median number of surgeries per site was 44 (interquartile range, 17-65). The 5-year disease-free survival rates among stage IB1-IIB disease were 77.2%, 79.9%, and 84.5% for low-, mid-, and high-volume groups, respectively. On multivariable analysis, women in high-volume centers had a decreased risk of recurrence (adjusted hazard ratio [HR] 0.69, 95% CI 0.58-0.82, P<.001) and all-cause mortality (adjusted HR 0.73, 95% CI 0.59-0.90, P=.003) compared with those in mid-volume centers. Specifically, women in high-volume centers had a decreased risk of local recurrence (adjusted HR 0.62, 95% CI 0.49-0.78, P<.001) but not distant recurrence (adjusted HR 0.85, 95% CI 0.67-1.06, P=.142) compared with those in mid-volume centers. Among 1,700 women with clinical stage IB1 disease treated with surgery alone, surgery at high-volume centers was associated with a decreased risk of recurrence (adjusted HR 0.45, 95% CI 0.25-0.79, P=.006) and all-cause mortality (adjusted HR 0.29, 95% CI 0.11-0.76, P=.013) compared with surgery at mid-volume centers on multivariable analysis. After propensity score matching, surgery at high-volume centers remained an independent prognostic factor for decreased recurrence (adjusted HR 0.69, 95% CI 0.57-0.84, P<.001) and all-cause mortality (adjusted HR 0.75, 95% CI 0.59-0.95, P=.016) compared with surgery at mid- and low-volume centers on multivariable analysis. CONCLUSION: Hospital volume for radical hysterectomy may be a prognostic factor for early-stage cervical cancer. Surgery at high-volume centers is associated with decreased local recurrence risk and improved survival.

IMPORTANCE: The efficacy of taxane plus platinum regimens has been demonstrated for advanced or recurrent endometrial cancer; however, it has not been assessed in postoperative adjuvant chemotherapy for endometrial cancer. OBJECTIVE: To evaluate the clinical benefit of taxane plus platinum compared with standard doxorubicin plus cisplatin as postoperative adjuvant chemotherapy in endometrial cancer. DESIGN, SETTING, AND PARTICIPANTS: In this multicenter, open-label, phase 3 randomized clinical trial, patients with endometrial cancer at high-risk stage I or II or stage III or IV that did not extend beyond the abdominal cavity and had 2 cm or greater residual tumor were included from 118 institutions in Japan from November 24, 2006, to January 7, 2011. Data was analyzed from March 15, 2017, to June 30, 2017. INTERVENTIONS: Eligible patients were randomly assigned (1:1:1) to receive 6 cycles of doxorubicin, 60 mg/m2, plus cisplatin, 50 mg/m2, on day 1; docetaxel, 70 mg/m2, plus cisplatin, 60 mg/m2, on day 1; or paclitaxel, 180 mg/m2, plus carboplatin (area under the curve, 6.0 mg/mL × min) on day 1 every 3 weeks. MAIN OUTCOMES AND MEASURES: The primary end point was progression-free survival. Secondary end points were overall survival, occurrence of adverse events, tolerability, and status of lymph node dissection. RESULTS: Among 788 eligible patients, the median (SD) age was 59 (22-74) years; 263 patients were assigned to doxorubicin plus cisplatin treatment, 263 patients to docetaxel plus cisplatin treatment, and 262 patients to paclitaxel plus carboplatin treatment. The number of patients who did not complete 6 cycles was 53 (20.1%) for the doxorubicin plus cisplatin group, 45 (17.1%) for the docetaxel plus cisplatin group, and 63 (24.0%) for the paclitaxel plus carboplatin group. Tolerability of these regimens were not statistically different. After a median follow-up period of 7 years, there was no statistical difference of progression-free survival (doxorubicin plus cisplatin, 191; docetaxel plus cisplatin, 208; paclitaxel plus carboplatin, 187; P = .12) or overall survival (doxorubicin plus cisplatin, 217; docetaxel plus cisplatin, 223; paclitaxel plus carboplatin, 215; P = .67) among the 3 groups. The 5-year progression-free survival rate was 73.3% for the doxorubicin plus cisplatin group, 79.0% for the docetaxel plus cisplatin group, and 73.9% for the paclitaxel plus carboplatin group, while the 5-year overall survival rates were 82.7%, 88.1%, and 86.1%, respectively. CONCLUSIONS AND RELEVANCE: There was no significant difference of survival among patients receiving doxorubicin plus cisplatin, docetaxel plus cisplatin, or paclitaxel plus carboplatin as postoperative adjuvant chemotherapy for endometrial cancer. Because each regimen showed adequate tolerability but different toxic effects, taxane plus platinum regimens may be a reasonable alternative to treatment with doxorubicin plus cisplatin.

STUDY OBJECTIVE: To show total laparoscopic complete resection of a recurrent low-grade endometrial sarcoma. DESIGN: Step-by-step demonstration of the technique of laparoscopic anterior pelvic exenteration with super radical parametrectomy, including the explanation of detailed pelvic anatomy (Canadian Task Force classification III). SETTING: Low-grade endometrial stromal sarcoma (LGESS) is a rare malignancy that makes up around 0.2% of all uterine malignancies [1]. Total abdominal hysterectomy and bilateral salpingo-oophorectomy is a standard treatment; however, the recurrence risk is quite high [2]. For a recurrent LGESS that is resistant to hormone therapy and chemotherapy, complete resection with negative surgical margins (R0 resection) can be the most promising method [3]. PATIENT: The patient had undergone total abdominal hysterectomy and bilateral salpingo-oophorectomy because of a LGESS. Almost 20 years later, a recurrent LGESS was detected at the vaginal stump, and the patient underwent several rounds of chemotherapy and hormonal therapy. These treatments were inefficacious, and the recurrent tumor progressed. An abdominal computed tomographic scan revealed that the recurrent tumor occupied the vaginal stump, involved the bladder and the left ureter, and extended to the left pelvic sidewall. INTERVENTIONS: Anterior pelvic exenteration with super radical parametrectomy was performed laparoscopically with no blood transfusion. R0 resection could be achieved without any intraoperative and postoperative complications. Without any adjuvant treatment, there has been no sign of recurrence during the 12 months that have passed since the surgery. This video obtained institutional review board approval through our local ethics committee in the Cancer Institutional Hospital (institutional review board number 2016-1007). CONCLUSION: The good visualization and meticulous dissection provided during laparoscopic surgery can make the approach advantageous and may contribute to R0 achievement.

STUDY OBJECTIVE: To show a novel combination laparoscopic and open perineal approach to complete resection of aggressive angiomyxoma. DESIGN: Step-by-step video demonstration of the combination approach (Canadian Task Force classification III). SETTING: Combined laparoscopic and open perineal approach was performed in the tertiary center. PATIENT: A 46-year-old woman presented with an 8-cm vulvar mass, diagnosed as an aggressive angiomyxoma. The patient, who strongly desired to preserve her uterus and ovaries, provided informed consent for resection of the tumor by our combination approach, also approved by our Institutional Review Board. INTERVENTION: Combined laparoscopic and open perineal approach. MEASUREMENTS AND MAIN RESULTS: Aggressive angiomyxoma is a rare mesenchymal neoplasm that occurs most often in the female pelviperineal region [1]. Aggressive angiomyxoma is locally infiltrative, and high postoperative local recurrence rates (36%-72%) due to incomplete resection have been reported [2]. Therefore, until recently, wide surgical excision with tumor-free margins have been the most commonly accepted treatment. However, aggressive angiomyxoma is a benign, slow-growing tumor, and because extensive surgical resection, which is associated with high operative morbidity rates, has not been shown to have a significant effect on prognosis, a more conservative procedure may be preferable [3]. The mass was located mainly at the left ischiorectal fossa, but it extended above the pelvic diaphragm and was attached to internal obturator muscle, vagina, bladder, urethra, and rectum. We excised the tumor completely and without complications by a combined laparoscopic and open perineal approach. Twelve months have passed since the surgery, and there has been no adjuvant treatment and no sign of recurrence. CONCLUSION: Our combination approach to aggressive angiomyxoma in the pelviperineal region is technically feasible, and the good visualization and meticulous dissection provided during the laparoscopic portion of the surgery contribute to complete resection.

OBJECTIVE: We aimed to develop and reinforce a clinical management regimen for atypical endometrial cell (ATEC) categories within the descriptive reporting format for endometrial cytology. METHODS: Between January 2013 and December 2014, 215 samples, for which histological examination was performed immediately or within 3 months after cytology, were cytologically diagnosed as ATEC. For these samples, the medical records were retrospectively reviewed to identify risk factors for malignancy. RESULTS: Among 152 samples diagnosed as ATEC, of undetermined significance, 19 (12.5%) were malignant. In the younger group (age <55 years), the χ2 values of body mass index (BMI) ≥25 kg/m2 (5.85), gravidity (5.64) and parity (5.15) were relatively high, suggesting that these were risk factors for malignancy. Of the nulligravida patients, those with BMI ≥25 kg/m2 , 28% were diagnosed with malignant disease. In the older group (≥55 years), endometrial thickening (6.84), atypical genital bleeding (6.43) and BMI ≥25 kg/m2 (3.79) were found to be risk factors for malignancy. Of the patients with endometrial thickening and atypical genital bleeding, 67% were diagnosed with malignant disease. Among 63 samples diagnosed as ATEC, cannot exclude atypical endometrial hyperplasia or more, 35 (55.6%) samples were positive for malignancy. CONCLUSIONS: High-risk patients diagnosed with ATEC, of undetermined significance were identified. Endometrial biopsy should be considered for nulligravida patients aged <55 years with a BMI ≥25 kg/m2 .

OBJECTIVE: This multicenter phase II Japanese Gynecologic Oncology Group study (JGOG1067) was designed to evaluate the efficacy and safety of postoperative chemotherapy in patients with node-positive cervical cancer. METHODS: Patients with stage IB-IIA squamous cervical cancer who underwent radical hysterectomy and were confirmed to have pelvic lymph node metastasis were eligible for this study. The patients postoperatively received irinotecan (CPT-11; 60mg/m2 intravenously on days 1 and 8) and nedaplatin (NDP; 80mg/m2 intravenously on day 1). Chemotherapy administration commenced within 6weeks after surgery and was repeated every 28days for up to 5cycles. The primary endpoint of this study was the 2-year recurrence-free survival (RFS) rate. The secondary endpoints were the 5-year overall survival (OS) rate, 5-year RFS rate, and adverse events such as complications of chemotherapy and lower-limb edema. RESULTS: Sixty-two patients were analyzed according to our protocol, among whom 55 (88.7%) completed 5cycles of scheduled treatment. The median follow-up period was 66.1months (range, 16.8-96.6months). The 2-year and 5-year RFS rates were 87.1% (95% confidence interval [CI]: 75.9-99.3) and 77.2% (95% CI: 64.5-85.8), respectively. Fourteen patients (22.5%) experienced recurrence during the follow-up period, 8 of whom died of the disease. The 5-year OS rate in this study was 86.5% (95% CI: 74.8-93.0). Only 9.7% of the patients experienced lymphedema in their legs. CONCLUSION: Postoperative chemotherapy without radiotherapy was found to be very effective in high-risk patients with node-positive cervical cancer.

Pegylated liposomal doxorubicin (PLD) has a good safety profile, but long-term use has been associated with development of squamous cell carcinoma of the tongue and oral cavity (SCCTO) in some patients. The study objective was to estimate the prevalence of oral leukoplakia, a known precursor of SCCTO, in patients with ovarian cancer and long-term PLD use.After approval of the institutional review board, medical record of 114 patients who were treated with PLD at our institution between January 2010 and December 2016 were retrospectively reviewed. All those patients have been referred for routine monitoring of oral mucositis every time before administration by a dentist. The patient characteristics included in the evaluation were age, smoking and drinking habits, the PLD dose and schedule, and presence or absence of oral leukoplakia and SCCTO at each oral examination. The relationships of the incidence of oral leukoplakia and patient characteristics were analyzed.The median total PLD dose was 160 (range 40-1550)âmg/m. Oral leukoplakia was seen in 6 (5.3%) patients. The median PLD dose, at the time of oral leukoplakia diagnosis, was 685 (range 400-800)âmg/m. SCCTO was not found. Univariate analysis revealed that age, Brinkman index, and habitual drinking were not considered as risk factors for oral leukoplakia, and only total PLD dose (OR, 1.470; 95% CI, 1.19-1.91; Pâ<â.001) remained as a significant independent risk factor for oral leukoplakia. The ROC curve analysis indicated that the optimal cutoff value of the total PLD dose to predict development of oral leukoplakia was 400âmg/m. The sensitivity was 100% and the specificity was 88.8%. No patient discontinued PLD because of oral leukoplakia or SCCTO.The 2 most important clinical observations were the occurrence of oral leukoplakia in patients with long-term PLD use and that the development of oral leukoplakia was related to a total cumulative dose ≥400âmg/m. Routine oral surveillance is recommended, particularly when the cumulative total dose exceeds 400âmg/m.

BACKGROUND: As atypical polypoid adenomyoma (APA) has been reported to be a hormone-related tumor, we aimed to analyze the efficacy and safety of maintenance hormonal therapy after fertility-preserving treatment of these patients with medroxyprogesterone acetate (MPA). METHODS: Data were retrospectively analyzed from patients with APA who were treated with a fertility-preserving regimen including MPA between October 2001 and December 2011. Eighteen patients were treated with MPA and 14 (77.8%) achieved either a complete or a partial response after the planned treatment. Five patients took progestin for maintenance therapy. RESULTS: Eighteen patients were treated for a mean observation period of 96.7 months. While taking the maintenance therapy, no patient had APA relapse. One patient developed well-differentiated endometrioid adenocarcinoma 18 months after she stopped taking maintenance progestin. Eleven patients without maintenance therapy underwent hysterectomy, andnine of them developed well-differentiated endometrial cancer. Through univariate analysis, there was a significant difference in time to hysterectomy between patients with and without maintenance therapy (P = 0.015). Through multivariate analysis, body mass index (BMI), menstrual status before protocol therapy, maintenance treatment, and pregnancy were found to be significantly associated with a lower risk of hysterectomy. No patient had a recurrence of APA after hysterectomy during the observation period (median, 54 months; range, 2-148 months). CONCLUSION: No patient showed progression while receiving hormonal therapy, including initial protocol therapy. Maintenance hormonal therapy after treatment with MPA was highly effective and safe, particularly in patients with BMI â§24 kg/m2 and irregular menstruation cycle.

OBJECTIVE: The aim of this study was to investigate the clinical usefulness of the placement of a transanal drainage tube (TDT) to prevent anastomotic leakage after a modified posterior pelvic exenteration (MPPE) for the treatment of primary ovarian cancer. METHODS: We performed a retrospective review of all the consecutive patients who had undergone an MPPE for primary ovarian, tubal, or peritoneal cancer between October 2012 and November 2016 at our institution. Patient-related, disease-related, and surgery-related data were collected. RESULTS: One hundred five patients who underwent an MPPE were included in this study. A TDT was placed in all the patients. A diverting ileostomy was created during cytoreductive surgery in 7 patients (7%). Those who underwent a diverting ileostomy tended to have a greater degree of surgical invasiveness, as was reflected by a longer operative time, a serious loss of blood, and a large quantity of intraoperative blood transfusion. Anastomotic leakage occurred in 1 patient (1%), and a diverting ileostomy was created for this patient. CONCLUSIONS: Transanal drainage tube placement seems to be an effective and safe procedure that can decrease the rate of anastomotic leakage and the need for a diverting stoma after MPPE for ovarian cancer. However, some patients inevitably require a diverting stoma despite the TDT placement.

To compare secondary cytoreductive surgery (SCS) plus chemotherapy with chemotherapy alone in Japanese patients with recurrent epithelial ovarian, tubal, or peritoneal cancer (ROC).From our institutional database, we identified 112 patients who underwent therapy for ROC between 2005 and 2013. Of the 112 patients, 77 received salvage chemotherapy alone (CT group) and 35 received SCS plus chemotherapy (SCS group). To reduce the impact of treatment selection bias on treatment outcomes, propensity score-matching analysis was used.In the entire cohort, prognostic features were poorer in the CT group than in the SCS group. The platinum-free interval was significantly lower (15.35 months vs 30.77 months), cancer antigen 125 (CA125) level was significantly higher (247.38âIU/mL vs 83.17âIU/mL), and number of solitary recurrence sites was significantly lower in the CT group than in the SCS group. The matched cohort consisted of 29 CT and 29 SCS patients with a median follow-up period of 24 and 58 months, respectively. In the matched cohort, progression-free survival (PFS) was longer in the SCS group than in the CT group (Pâ=â.02); however, overall survival did not differ (Pâ=â.23).SCS might be associated with improved PFS in ROC patients. SCS is beneficial in appropriately selected ROC patients.

STUDY OBJECTIVE: To show total laparoscopic resection of a cervical carcinoma that recurred at the left pelvic sidewall after radical hysterectomy and concurrent chemoradiotherapy (CCRT). DESIGN: A step-by-step demonstration of the technique in a surgical video, including the strategy for achieving complete surgical resection with negative margins (R0 resection) (Canadian Task Force Classification III). SETTING: For high-risk cervical carcinoma, radical hysterectomy and adjuvant CCRT is the standard treatment, but even this multimodal therapy cannot prevent recurrence. When the recurrent mass is localized in the pelvic cavity, R0 resection offers the most promise; however, for laterally recurring cervical carcinoma, the resectability rate is low, owing mainly to severe adhesion and fibrosis, and thus the morbidity and mortality rates are high. Because laparoscopy optimizes visualization and provides for meticulous dissection, laparoscopic surgery can be advantageous over open surgery for resection of cervical carcinoma recurring at the pelvic sidewall after radical hysterectomy and adjuvant CCRT. INTERVENTIONS: A 48-year-old woman with stage IB2 cervical adenocarcinoma had undergone radical hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy, and, because lymph node metastasis was found in the removed lymph nodes, adjuvant CCRT. At 6 months after completion of this multimodal therapy, a recurrent mass was detected at the left pelvic sidewall. The mass involved the left ureter, bladder, left internal iliac vessels, and endopelvic fascia, and left renal function was unrecoverable. Tumor excision and left nephroureterectomy were performed laparoscopically. The total operating time was 608 minutes, blood loss volume was 250 mL, and blood transfusion was not required. Complete tumor clearance (R0 resection) was achieved by resection of the left internal iliac vessels, left internal obturator muscle, left pubococcygeal muscle, left ureter, and bladder. There were no postoperative complications. Institutional Review Board approval was obtained through our local Ethics Committee in Cancer Institute hospital. CONCLUSION: Complete laparoscopic resection surgery for recurrent cervical carcinoma at the pelvic sidewall after radical hysterectomy and adjuvant CCRT is technically feasible. The good visualization and meticulous dissection provided during laparoscopic surgery make the approach advantageous for the management of laterally recurrent cervical carcinoma.

BACKGROUND: Though laparoscopic surgery has recently been applied in the treatment of early-stage endometrial cancer, the presence of a large uterus is a hindrance to specimen extraction from the abdominal cavity. We describe a laparoscopic surgical technique for endometrial cancer involving the extraction of the resected specimen through an umbilical zigzag incision. CASE PRESENTATION: A 63-year-old woman with endometrial cancer underwent a total hysterectomy and bilateral salpingo-oophorectomy that was performed laparoscopically. The surgical specimen was extracted through an umbilical zigzag incision. This umbilical zigzag incision created a larger fascial and peritoneal opening, facilitating the removal of the specimen. The final histopathologic results revealed stage 1A G1 endometrioid adenocarcinoma and multiple uterine leiomyomas. Three months after surgery, the wound in the umbilical region was inconspicuous, along with the inward movement of the umbilicus. CONCLUSIONS: A laparoscopic surgical technique for endometrial cancer involving the extraction of the specimen through an umbilical zigzag incision seems to reduce the difficulties associated with laparoscopic surgery and maintains cosmesis. Further analyses involving larger numbers of cases and long-term follow-up periods are warranted to evaluate this surgical method.
