RESUMO

Robotic-assisted surgery enables precise manipulations with magnified vision, stereoscopic vision, and forceps with multi-joint functions. It requires unique procedures such as position setting, port placement, roll-in, and docking, which lead to prolonged operation and anesthesia time. Five conditions described below were established at our institution to reduce the time to the initiation of console: (1) changing the patients' position from the flat lithotomy position to the spread legs position; (2) attaching a Hasson cone to hold the umbilical cannula stable; (3) changing the cannula's obturator (inner tube) from blunt to bladeless; (4) fixing the team, and (5) conducting regular docking training. These outcomes were examined in this study. The study included 77 patients who underwent robotic-assisted total hysterectomy for benign uterine disease and stage IA uterine cancer at our individual institution between April 2019 and July 2022. We compared the median time from anesthesia to console initiation between the first half group (cases 1-40) and the second half group (cases 41-77). The former required 91.5 (53-131) minutes, whereas the latter required 59 (37-126) minutes. Appropriate equipment selection and team education can reduce the time to console initiation.

RESUMO

Adenocarcinoma, HPV-independent, mesonephric type (hereafter referred to as "mesonephric carcinoma") arising from the cervix is rare, its treatment has not been established, and its sensitivity to chemotherapy has not been fully investigated. Here we report on a 30-year-old female patient who presented at our hospital with a chief complaint of abnormal genital bleeding. We suspected cervical cancer. Based on examination, biopsy, and imaging, she was diagnosed with stage IIA2 adenocarcinoma of the cervix and was scheduled for surgery. Because she had a SARS-COV-2 infection, she was given two courses of paclitaxel-carboplatin (TC) therapy, based on the then-current surgical risk assessment after SARS-COV-2 infection, with a waiting period of at least 8 weeks. The patient was deemed to have a partial response and was treated with paclitaxel and carboplatin, after which she was deemed to have a partial response and underwent total hysterectomy. A diagnosis of stage IIA2 mesonephric carcinoma, ypT1b2N0M0, was made after histopathologic examination of an excised specimen. The patient was treated with 4 additional courses of TC therapy after surgery, and has had no recurrence in 13 months. We report a first case of response to neoadjuvant chemotherapy with TC regimen in a patient with mesonephric carcinoma of the cervix.

RESUMO

Most cases of tubo-ovarian abscess (TOA) are due to transvaginal infection, while other internal diseases may also be associated with TOAs. We experienced a case of ovarian clear cell carcinoma and rectal carcinoma that was discovered to be a result of TOA. A 46-year-old woman was diagnosed with TOA and referred to our hospital. Laparoscopic abscess drainage was performed, and pathological findings confirmed the presence of ovarian clear cell carcinoma inside the abscess. The tumor marker carcinoembryonic antigen (CEA) was elevated, and rectal cancer was diagnosed by a gastrointestinal endoscopy. Abdominal computed tomography (CT) showed a left adnexal abscess with an air image inside, and penetration of the abscess wall and rectal cancer were observed. Histopathologically, there was an accumulation of neutrophils around the rectal tumor cells. We concluded that the rectal cancer had penetrated the existing ovarian tumor and formed TOA. Non-gynecological diseases may be associated with TOA. It is necessary to consider the possibility that other clinical diseases may be associated with the trigger of TOA.

RESUMO

Giant cell tumor is a highly aggressive tumor characterized by a marked proliferation of pleomorphic, bizarre giant cells usually observed in the lungs. The importance of histopathological imaging and the clinical course of this tumor are unknown. The objective of our report was to investigate whether these components affect treatment outcomes and prognosis compared to conventional cancers. A 40-year-old woman with cervical cancer showed leukocytosis and elevated granulocyte colony simulating factor (G-CSF). The patient underwent a radical abdominal hysterectomy. Pathology revealed a poorly differentiated squamous cell carcinoma of the cervix, similar to giant cell carcinoma. The patient recovered from the disease and is alive 37 months after concurrent chemoradiotherapy (CCRT). Leukocytosis and G-CSF were normalized after treatment. This was our second case of giant cell carcinoma of the cervix. Cumulative data on giant cell carcinoma are limited, thus we considered the prognostic significance of the presence of giant cell carcinoma in uterine carcinoma.

RESUMO

A combination chemotherapy of paclitaxel plus carboplatin (TC) is the most frequently used regimen for gynecological malignancies. As long as it is effective, a carboplatin-containing combination chemotherapy is used for every relapse. This implies that the number of platinum administrations and the frequency of hypersensitivity reaction (HSR) increase as the prognosis improves. When a patient develops HSR to carboplatin, we have three options: 1) desensitizing and continuing to use carboplatin, 2) switching to other platinum drugs, or 3) changing to a non-platinum drug. Here we report an experience of an HSR to carboplatin in a patient with recurrent uterine carcinosarcoma. The patient was treated by surgery and TC therapy initially, resulting in no residual disease. The patient relapsed 18 months after the completion of the first-line chemotherapy and was treated with TC therapy again as second-line. An HSR to carboplatin occurred at the 10th cycle of TC in total. We replaced the carboplatin with cisplatin. A chemotherapy including cisplatin and adriamycin was repeated without further HSR. We reviewed the literature regarding HSR to carboplatin and in this paper we summarize the management for dealing with it.

RESUMO

Endometrioid carcinoma is the most common histological type of concurrent synchronous cancers of the uterus and ovary. Here we report a case of synchronous seromucinous carcinoma of the ovary and mucinous carcinoma of the endometrium with a literature review. A 51-year-old multiparous female complained of irregular bleeding and shortness of breath. Computed tomography revealed a large pelvic mass that consisted of cystic and solid components, a tumor of the endometrium, and a large amount of pleural effusion. An endometrial biopsy indicated adenocarcinoma, and adenocarcinoma cells were found in the pleural fluid. The patient with advanced ovarian cancer or endometrial cancer with massive pleural effusion received three courses of neoadjuvant chemotherapy (NAC) with paclitaxel and carboplatin followed by interval debulking surgery (IDS). The NAC was effective, and IDS was performed with no gross residual lesions. The post-operative diagnosis was seromucinous carcinoma of the ovary in FIGO (2014) stage IVA (ypT3cNxM1a) and mucinous carcinoma of the endometrium in FIGO (2008) stage IA (ypT1aNXM0). Three courses of postoperative TC therapy were performed, and maintenance therapy with Bevacizumab is ongoing. The patient is well without evidence of recurrence, sixteen months after surgery.

RESUMO

Adventitial cystic disease (ACD) is a rare condition in which a mucinous cyst forms within the adventitia, usually in arteries but rarely in veins. A 79-year-old patient presented with stomachache and nausea. Computerized tomography showed pelvic cysts on either side of the pelvis. The right tumor was 120×100 mm, and the left tumor was 45×35 mm. Our diagnosis was bilateral ovarian tumors and we performed laparoscopic tumor resection. In the abdominal cavity, we saw that the left ovary was swollen by about 3-4 cm and the right ovary was normal size. There was a mucous cyst located in the right retroperitoneal cavity that adhered around and bordered the right external iliac vein and the right obturator nerve. We peeled the adhesion away carefully and resected the tumor but the operation caused temporary obturator nerve paralysis. From pathological examination, we diagnosed the right retroperitoneal cyst to be venous ACD originating from the right external iliac vein. We found that venous ACD can grow as large as a pelvic tumor and is difficult to distinguish from an ovarian tumor, which is why we chose laparoscopic surgery. In this case, we performed the operation laparoscopically and no sequelae or recurrent tumor appeared during a 1-year follow-up. However, graft replacement is sometimes necessary for ACD, thus venous ACD should be considered a differential diagnosis and a surgical strategy should be developed when pelvic tumors are observed.

RESUMO

BACKGROUND: BK-UM (CRM197) is a mutant form of diphtheria toxin and a specific inhibitor of heparin-binding epidermal growth factor-like growth factor (HB-EGF). We assessed the safety, pharmacokinetics, recommended dose, and efficacy of BK-UM in patients with recurrent ovarian cancer (OC) or peritoneal cancer (PC), and measured HB-EGF levels in serum and abdominal fluid after BK-UM administration. METHODS: Eleven patients with advanced or recurrent OC or PC were enrolled and treated with BK-UM via the intraperitoneal route. The dose was escalated (1.0, 2.0, 3.3, and 5.0 mg/m2) using a 3 + 3 design. RESULTS: Eight of 11 patients completed treatment. No dose-limiting toxicity (DLT) was experienced at dose levels 1 (1.0 mg/m2) and 2 (2.0 mg/m2). Grade 3 transient hypotension as an adverse event (defined as a DLT in the present study) was observed in two of four patients at dose level 3 (3.3 mg/m2). Treatment with BK-UM was associated with decreases in HB-EGF levels in serum and abdominal fluid in seven of 11 patients and five of eight patients, respectively. Clinical outcomes included a partial response in one patient, stable disease in five patients, and progressive disease in five patients. CONCLUSIONS: BK-UM was well tolerated at doses of 1.0 and 2.0 mg/m2, with evidence for clinical efficacy in patients with recurrent OC or PC. A dose of 2.0 mg/m2 BK-UM is recommended for subsequent clinical trials. TRIAL REGISTRATION: This trial was prospectively performed as an investigator-initiated clinical trial. The trial numbers are UMIN000001002 and UMIN000001001, with registration dates of 1/30/2008 and 2/4/2008, respectively. UMIN000001001 was registered as a trial for the continuous administration of BK-UM after UMIN000001002 .

RESUMO

Dienogest is a novel progestin with potent oral progestational activity that inhibits the clinical symptoms of endometriosis. We herein evaluated the effect of dienogest on ovarian endometriotic cysts via immunohistochemistry. Ovarian endometriotic cyst specimens were collected from 12 patients treated with dienogest and 20 patients not treated with hormones (controls). The expression of estrogen receptor (ER)-α, progesterone receptor A (PRA), and Ki-67 was studied by immunohistochemistry. As compared with the controls, the cell proliferation index was significantly reduced in both epithelial and stromal cells of the endometriotic cysts following the use of dienogest (P = 0.022 and P = 0.004, respectively). However, there was no significant difference between endometriotic cysts with and without the use of dienogest in the expressions of ER-α and PRA in the epithelial and stromal cells. Irrespective of the use of dienogest, the expression levels of ER-α and PRA in the epithelial cells were low (median: 32% and 8%, respectively). Conversely, the expression levels of ER-α and PRA in the stromal cells were well preserved (median: 68% and 92%, respectively). In the controls, there was no significant difference between endometriotic cysts in the expression levels of Ki-67, ER-α and PRA in epithelial and stromal cells during the proliferative and secretory phases. The finding of a reduction in the cell proliferation index by the use of dienogest with no change in the expressions of hormonal receptors may not support the direct progestational effect of dienogest on ovarian endometriotic cysts.

RESUMO

A 31-year-old nulligravid woman with a 3 year history of infertility visited our hospital. After consultation and a transvaginal ultrasound and MR imaging, her uterine anomaly was identified as complete septate uterus: class V (a) by the American Fertility Society (AFS). She had a doubled uterine cervix and a vaginal septum. Hysteroscopic metroplasty was performed with the aid of a laparoscopy. Both tubal patencies were confirmed with indigocarmine in a laparoscopic image. Laparoscopic electronic cautery was also done on the left ovarian endometrioma (stage 1 endometriosis; the revised American Society for Reproductive Medicine (rASRM) classification 4 point minimal). We distrained an intrauterine device in the uterine cavity and removed it after two cycles of menstruation. The patient subsequently became pregnant during her third menstrual cycle and the current progress of her pregnancy is favorable.

RESUMO

INTRODUCTION: Herlyn-Werner-Wunderlich syndrome (HWWS) is characterized by uterine didelphys, unilateral cervical obstruction, and ipsilateral renal defects. Owing to its rarity, no standard surgical approach exists. PRESENTATION OF CASE: An 11-year-old girl with severe dysmenorrhea had a duplicated uterus, a right cervical hemorrhagic cyst, and right ipsilateral kidney agenesis, indicative of HWWS. As transvaginal surgery was challenging, we turned to laparoscopic surgery for abdominal cavity inspection and surgical assistance. A longitudinal incision was made on the right uterus, followed by inserting a catheter tube fixed to an intrauterine device (IUD) into the right cervical canal from the anterior wall of the right uterine horn. Subsequently, the right external cervical os was inverted to prevent restenosis. Postoperatively, the hemorrhagic cyst at the right cervix disappeared. The patient had no symptom recurrence 24 months after the surgery. DISCUSSION: The preoperative diagnosis for female genital malformations is complicated, and transvaginal manipulation is often difficult in adolescent girls. Laparoscopy is a valuable tool for evaluating female genital malformations, allowing for a thorough diagnosis and safe surgical treatment. In cases of female genital malformation with cervical obstruction, as in this case, reconstruction of the uterine cervix is important to prevent restenosis after surgery. CONCLUSION: In female genital malformations, laparoscopy provides a comprehensive evaluation of the malformation, assisting in a precise diagnosis and safe surgical treatment. Insertion of the catheter tube with IUD into the uterus and reconstruction of the cervix contribute to preventing restenosis.

RESUMO

Cytokine release syndrome (CRS) is a systemic inflammatory condition caused by an excessive immune response and cytokine overproduction. CRS is a life-threatening condition that is often associated with chimeric antigen receptor T-cell therapy. Despite the increased use of immune checkpoint inhibitors (ICIs), ICI-induced CRS remains rare. The present study describes a case of CRS that occurred after the administration of ICIs for recurrent adenocarcinoma of the uterine cervix. A 49-year-old woman received paclitaxel, carboplatin and pembrolizumab for recurrent cervical adenocarcinoma. On day 27 of the third cycle, the patient was admitted with a fever and suspected pyelonephritis. The following day, hypotension, upper respiratory symptoms and myalgia of the extremities were noted, and the left ventricular ejection fraction (LVEF) was decreased to 20%. Multiorgan failure (MOF) occurred, and the patient received ventilator support and continuous hemodiafiltration. Rhabdomyolysis, pancreatitis, erythema multiforme and enteritis were observed. CRS was diagnosed based on elevated ferritin and IL-6 levels. Steroid pulse therapy was administered; however, the MOF did not improve and the anti-IL-6-receptor monoclonal antibody tocilizumab (TOC) was administered. Subsequently, the LVEF improved to 50%, and the patient was removed from the ventilator on day 4 and from the continuous hemodiafiltration unit on day 6 after TOC administration. The patient was discharged on day 21. In conclusion, considering that ICI-induced CRS is a rare but severe complication, fever and other systemic conditions following ICI administration should be monitored.

RESUMO

There is currently controversy regarding the criteria for low and intermediate risk of cervical cancer (CC) after surgery. In the present study, the Gynecology Oncology Group (GOG) score was used to detect intermediate risk. Adjuvant radiotherapy was applied in the case of a GOG score >120. The present study aimed to evaluate the validity of the recurrence risk classification using the GOG score for stage IB-IIA node-negative CC. All cases of stage IB-IIA node-negative CC who underwent radical surgery between February 2007 and December 2015 were retrospectively reviewed. The GOG scores were determined from clinical and pathological findings and accordingly, subjects were divided into 4 groups: A, ≤40; B, >40 and ≤70; C, >70 and ≤120; and D, >120. Overall survival (OS) and recurrence-free survival (RFS) curves were generated using the Kaplan-Meier method. The log-rank test produced an estimated P-value by comparing the OS and RFS of group A (low-score group) with those of others. The present study included 61 patients (mean age, 47.82 years; age range, 22-76 years) and the median follow-up was 79 (39-149) months. Of these, 60 patients were observed for at least 60 months. During the follow-up period, the OS and RFS rates of group C were 94.7 and 84.2%, respectively, while those of group D were 100 and 91.7%, respectively; the OS and RFS of groups A and B were 100%. Log-rank tests for all OS and RFS indicated no significant differences compared to group A. It was indicated that a GOG score ≤70 does not require adjuvant therapy; however, a GOG score >70 requires consideration of adjuvant therapy based on the risk factors which constitute the score.

RESUMO

Intra-tumoral budding (ITB) has been well demonstrated to be an independent risk factor for adverse outcomes in colorectal carcinoma. This study investigated the prognostic significance of ITB in high-grade serous ovarian carcinomas (HGSOCs). The medical records and slides of 84 SOCs, including 13 with neoadjuvant chemotherapy (NAC), were retrospectively reviewed. The histopathologic examination with scoring of p53 expression showed them to be 80 HGSOCs and 4 low-grade serous ovarian carcinomas (LGSOCs). ITB was found in 64 (80.0%) of the 80 HGSOCs and 1 (25.0%) of 4 LGSOCs. The presence of ITB in HGSOC was significantly correlated with a higher level of CA125, an advanced 2014 FIGO stage, the presence of Lymph node metastasis, and the presence of lymphovascular space invasion (LVSI). The median progression-free survival (PFS) was 18 months in patients with HGSOC with ITB and 36 months in patients with HGSOC without ITB (P = 0.006), and their median overall survival (OS) was 50 months and 60 months (P = 0.060). The multivariate analysis revealed that ITB was not an independent prognostic factor. ITB is a cost-effective prognostic indicator for patients with HGSOC and ITB in ovarian tumor tissue is considered a useful histological biomarker of the progression of HGSOCs.

RESUMO

PURPOSE OF REVIEW: Therapeutics targeting the ErbB protein family receptors have not always yielded favorable or successful results in present cancer therapy. This review discusses the possibility of the clinical adaptation of targeting against heparin-binding epidermal growth factor-like growth factor (HB-EGF), one of the ligands of the ErbB system, in ovarian cancer therapy. RECENT FINDINGS: We have previously described the results of studies concerning roles of HB-EGF in tumor formation in ovarian cancer. In brief, lisophosphatidic acid (LPA) and HB-EGF are predominantly expressed in advanced ovarian cancer, and LPA-induced, a disintegrin and metalloprotease-mediated ectodomain shedding of HB-EGF was found to be critical to tumor formation. We also noted that exogenous expression of HB-EGF enhanced tumor formation but inhibition blocked both extracellular signal-related kinase and serine/threonine protein kinase activation. Finally we investigated the antitumor effects of CRM197 - a specific HB-EGF inhibitor - on ovarian cancer cells by evaluating human ovarian cancer cell proliferation. SUMMARY: We discuss alternative strategies to develop the chemotherapeutic agent based on targeting ErbB family ligands rather than their receptors. A phase I study of CRM197 for advanced ovarian cancer has already begun, which is the first approved trial of ErbB-ligand-targeted therapy. We also discuss clinical adaptations based on combination of CRM197 with other conventional chemotherapeutic agents.

RESUMO

Primary sarcoma of the fallopian tube is a very rare neoplasm. We report the case of a 69-year-old woman affected with leiomyosarcoma of the left fallopian tube. Her chief complaint was lower abdominal pain. The preoperative diagnosis was a left adnexal malignant tumor based on pelvic examination, abdominal computed tomography, and magnetic resonance imaging. Following a laparotomy, she was ultimately diagnosed with a FIGO IIc fallopian tube leiomyosarcoma. She was treated with total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymph node dissection, partial omentectomy, and low anterior resection for rectal invasion. The patient subsequently received adjuvant chemotherapy with pirarubicin and ifosfamide. Thirty months after the first therapy, a computed tomography scan revealed metastasis of the liver, lung, and supraclavicular lymph node. The patient died of the disease 39 months after the initial treatment.

RESUMO

INTRODUCTION: A high incidence of endometrial K-ras mutations has been reported in tamoxifen (TAM)-treated patients with breast cancer. We examined the changes in the frequency of the endometrial K-ras mutations after the cessation of TAM treatment. METHODS: DNA was extracted from fresh cytological or polypectomy samples of the endometrium in 28 patients who had undergone TAM treatment of breast cancer. Mutations were detected by an enriched polymerase chain reaction-enzyme-linked minisequence assay (Sumitomo Metal Industry, Inc, Tokyo, Japan). K-ras codon 12 mutations were monitored in these 28 patients. RESULTS: An initial examination detected endometrial K-ras mutations in 13 of the 28 patients. However, repeated examinations performed after cessation of TAM treatment did not detect endometrial K-ras mutations in any of these 13 patients. No endometrial K-ras mutation has been detected in the repeated examinations performed for these patients for more than 2 years since the cessation of TAM treatment. In addition, the 15 patients who did not have endometrial K-ras mutations in the initial examination did not demonstrate them in repeat examinations. CONCLUSIONS: The cessation of TAM treatment may reduce the risk of developing endometrial cancers through K-ras mutations.

RESUMO

Granulocyte colony-stimulating factor (G-CSF) is commonly used in clinical practice to accelerate neutropenia recovery after chemotherapy. G-CSF is a myeloid growth factor produced by monocytes, macrophages, fibroblasts and endothelial cells. Generally, aortitis and arteritis are not a known side effect of G-CSF and is thought to be extremely rare. Here, we present a case of a 77-year-old woman who underwent adjuvant chemotherapy (combined paclitaxel and carboplatin) for ovarian cancer, and then developed acute arteritis after receiving G-CSF. She developed grade 4 neutropenia on day 7 of the third chemotherapy cycle and received six G-CSF administrations. Two days after G-CSF administration, she came down with a high-grade fever that persisted for 2 weeks. Laboratory tests revealed a white blood cell count of 8700 UI, neutrophilic sequestration of 61.5%, and C-reactive protein of 8.43 mg/dl at the highest point of her fever. Considering that we were initially treating neutropenia, we diagnosed a bacterial infection, and she was treated with a course of antibiotics. However, her blood and urinalysis cultures were negative, and antibiotics were ineffective; thus, we performed a computed tomography scan to search for the cause of her persistent fever. The computed tomography scan showed remarkable thickness of the bilateral common carotid artery and the left subclavian artery consistent with arteritis. With cessation of the antibiotics course, she was followed closely without therapy, and her condition resolved in a few days. We conclude that G-CSF induced arteritis due to our exclusion of other probable etiologies.

RESUMO

OBJECTIVES: Age-related changes in the expression of hormonal receptors have not been well examined in the fallopian tube (FT). We herein report the effect of menopause on the hormone receptors in ampullae of the FTs (AFTs), in comparison with cortical inclusion cysts (CICs) of the ovary. METHODS: A total of 84 AFTs and 16 fimbriae of FTs, which were obtained from 26 premenopausal and 58 postmenopausal women; and 27 postmenopausal CICs were immunohistochemically studied for the expression of p53, Ki-67, estrogen receptor-alpha (ER-α), and progesterone receptor A (PRA). Apoptotic cells were identified using a TUNEL assay. RESULTS: Postmenopausal AFTs showed a significantly lower labeling index (LI) for Ki-67 (P<0.001), apoptosis (P=0.03), and PRA (P<0.001) than premenopausal AFTs. No significant correlation with immunohistochemical markers was found in premenopausal AFTs, but the LI for PRA was positively correlated with that for Ki-67 (P=0.004) and inversely with that for p53 (P=0.023) in postmenopausal AFTs. The expression of immunohistochemical markers was closely correlated between ampullae and fimbriae of the FT. The p53 signature (p53S) was detected in five postmenopausal AFTs (mean age: 70.2 years) and was not detected in any CICs. The immunohistochemical profile of p53S was low expression of Ki-67, apoptosis, and PRA, and high expression of ER-α. The expression of PRA in CICs was significantly higher than that in AFTs (P=0.001). CONCLUSION: The expression of PRA was significantly lower in postmenopausal AFTs than in premenopausal AFTs, whereas the expression of PRA was well preserved in postmenopausal CICs.

RESUMO

AIM: This study aimed to evaluate the efficacy of aprepitant, a neurokinin (NK)1 receptor antagonist, on chemotherapy-induced nausea and vomiting (CINV). PATIENTS AND METHODS: A randomized, open-labeled, parallel-design study was undertaken in gynecologic-cancer (GC) patients at the Fukuoka University Hospital. Twenty-three patients were divided into without (group A) or with aprepitant (Group B) in the first cycle of paclitaxel and carboplatin (TC) therapy. From the second cycle onwards, all patients used aprepitant. Statistical significance was assessed using McNemar and Chi-square tests. RESULTS: In the first cycle, the prevalence of a complete response, no episodes of nausea or food intake in group B was significantly increased compared to group A. No significant difference in the prevalence of a complete response or food intake situation was found from the second cycle onwards. CONCLUSION: Combination of aprepitant with standard anti-emetic therapy may contribute to prevention of CINV in TC therapy for GC patients.
