RESUMO

RESEARCH QUESTION: What are ovarian stimulation cycle outcomes and acceptance rates of an oocyte accumulation programme in young women with benign ovarian tumour (BOT)? DESIGN: Retrospective cohort study conducted at the Academic Assisted Reproductive Technology and Fertility Preservation Centre, Lille University Hospital, between January 2016 and December 2019. The number of metaphase II oocytes per cycle and per patient after accumulation were evaluated. Two groups were identified for the analysis: endometrioma ('endometrioma') and dermoid, mucinous or serous cyst ('other cysts'). RESULTS: A total of 113 fertility-preservation cycles were analysed in 70 women aged 27.9 ± 4.8 years. Almost all women had undergone previous ovarian surgery before fertility preservation (89%). Mean anti-Müllerian hormone levels before ovarian stimulation was 12.5 ± 8.7 pmol/l. A total of 6.4 ± 3.4 oocytes were retrieved, and 4.3 ± 3.4 metaphase II (MII) oocytes were vitrified per cycle. All agreed to the oocyte accumulation programme and all underwent at least one cycle. To date, 36 (51%) patients achieved two or three fertility- preservation cycles. After accumulation, 7.0 ± 5.23 MII oocytes were vitrified per patient. No difference was found in ovarian response and oocyte cohort between the 'endometrioma' and 'other cysts' groups. Questionnaires completed after oocyte retrieval revealed abdominal bloating and pelvic pain in most patients, with no difference according to the type of cyst. No serious adverse events occurred. CONCLUSIONS: Oocyte accumulation should be systematically offered to young women with BOT irrespective of histological type, as it seems to be well-tolerated. Long-term follow-up is needed to assess the efficiency of oocyte accumulation to optimize the chances of subsequent pregnancies.

RESUMO

BACKGROUND/OBJECTIVES: Pancreatic cystic neoplasms (PCNs) are common, among which 13%-23% are serous cystic neoplasms (SCNs). However, diffuse and multifocal variants of SCNs are extremely rare. The differential diagnosis of SCNs from other PCNs is important as the former entities are benign and do not become invasive. OBJECTIVE: This study analyzes the clinical characteristics of multifocal/diffuse SCN through a systematic review of the literature and a case report. METHODS: A comprehensive literature search was executed in the Ovid MEDLINE, Embase, and Google Scholar databases. The search strategy was designed to capture the concept of multifocal/diffuse SCN cases with sufficient clinical information for detailed analysis. Using the final included articles, we analyzed tumor characteristics, diagnostic modalities used, initial management and indications, and patient outcomes. RESULTS: A review of 262 articles yielded 19 publications with 22 cases that had detailed clinical information. We presented an additional case from our institution database. The systematic review of 23 cases revealed that the diffuse variant is more common than the multifocal variant (15 vs 8 cases, respectively). Patients were managed with surgical intervention, conservative treatment, or conservative treatment followed by surgical intervention. Indications for surgery following conservative management mainly included new onset or worsening of symptoms. Only one case reported significant tumor growth after attempting an observational approach. No articles reported recurrence of SCN after pancreatectomy, and no articles reported mortality related to multifocal/diffuse SCNs. CONCLUSION: Despite their expansive-growing and space-occupying characteristics, multifocal/diffuse SCNs should be treated similarly to their more common unifocal counterpart.

RESUMO

Cystic neoplasms of the pancreas are being identified at an increasing frequency largely due to the increased use of abdominal cross-sectional imaging. These neoplasms represent a heterogeneous group of tumors with various genetic alterations, molecular features, and risks of malignancy. Despite the use of high-resolution radiographic studies, endoscopic evaluation, cyst fluid analysis, and novel molecular diagnostics, many of these lesions remain difficult to classify without operative resection. These diagnostic challenges are coupled with an improving but limited understanding of the natural history of these neoplasms. Treatment of pancreatic cystic neoplasms therefore remains controversial but consists largely of a selective tumor-specific approach to surgical resection. Future research remains necessary to better discriminate the biological behavior of these tumors in order to more appropriately select patients for operative intervention.

RESUMO

OBJECTIVES: Serous cystic neoplasm (SCN) is a cystic neoplasm of the pancreas whose natural history is poorly known. The purpose of the study was to attempt to describe the natural history of SCN, including the specific mortality. DESIGN: Retrospective multinational study including SCN diagnosed between 1990 and 2014. RESULTS: 2622 patients were included. Seventy-four per cent were women, and median age at diagnosis was 58 years (16-99). Patients presented with non-specific abdominal pain (27%), pancreaticobiliary symptoms (9%), diabetes mellitus (5%), other symptoms (4%) and/or were asymptomatic (61%). Fifty-two per cent of patients were operated on during the first year after diagnosis (median size: 40 mm (2-200)), 9% had resection beyond 1 year of follow-up (3 years (1-20), size at diagnosis: 25 mm (4-140)) and 39% had no surgery (3.6 years (1-23), 25.5 mm (1-200)). Surgical indications were (not exclusive) uncertain diagnosis (60%), symptoms (23%), size increase (12%), large size (6%) and adjacent organ compression (5%). In patients followed beyond 1 year (n=1271), size increased in 37% (growth rate: 4 mm/year), was stable in 57% and decreased in 6%. Three serous cystadenocarcinomas were recorded. Postoperative mortality was 0.6% (n=10), and SCN's related mortality was 0.1% (n=1). CONCLUSIONS: After a 3-year follow-up, clinical relevant symptoms occurred in a very small proportion of patients and size slowly increased in less than half. Surgical treatment should be proposed only for diagnosis remaining uncertain after complete workup, significant and related symptoms or exceptionally when exists concern with malignancy. This study supports an initial conservative management in the majority of patients with SCN. TRIAL REGISTRATION NUMBER: IRB 00006477.

RESUMO

BACKGROUND/AIMS: The aim of this study is to compare the distribution of anatomic sites of first recurrence in African American (AA) patients with ovarian carcinoma compared to Caucasians. METHODS: Patients diagnosed with high-grade epithelial ovarian, fallopian tube or peritoneal carcinoma from 2007 to 2013 were identified. Patterns of recurrence were compared for AA and Caucasian patients. Progression-free survival (PFS) and overall survival (OS) were compared. RESULTS: A total of 238 patients were included - 210 Caucasians and 28 AAs. At a follow-up time of 28 months, AAs were more likely to have multiple anatomic sites of recurrence rather than a single site when compared to Caucasians (63.6 vs. 35.5%, p = 0.01). Time to first recurrence was shorter for AA patients (12 vs. 18 months, p < 0.01). PFS and OS did not differ. AA patients with multiple sites of first recurrence had a significantly shorter OS than Caucasian patients with multiple sites of first recurrence (24 vs. 30 months, p = 0.022). CONCLUSION: Patterns of first recurrence differ between AAs and Caucasians. AAs have shorter times to first recurrence and are more likely to have multiple anatomic sites involved. AA patients with multiple sites of recurrence have a shorter OS than Caucasian patients with multiple sites.

RESUMO

The number of patients diagnosed with cystic pancreatic neoplasms (CPN) has increased significantly during the last decade due to the widespread use of cross-sectional imaging. These CPN consist of a heterogeneous group of neoplastic and non-neoplastic lesions with variable histopathological features, clinical presentation, and outcome. Until now we are not able to reliably identify all CPNs that require additional analysis, surgical resection or surveillance. Hence, physicians and surgeons are confronted with a difficult dilemma as they do not want to miss a diagnosis of pancreatic carcinoma, but this often leads to the risk of over- or misuse of diagnostic examinations with a risk of complications and increased health care costs. Currently, four expert consensus guidelines on cystic lesions of the pancreas are available. Unfortunately, recommendations vary considerably between these guidelines. The purpose of this review therefore was to compare the different guidelines and elaborate upon the topics where these guidelines disagree.

RESUMO

BACKGROUND: Serous cystadenoma is a benign pancreatic cystic neoplasm. Conservative management is favored. We studied the clinical characteristics and course of serous cystadenoma in patients undergoing surgery or conservative management only at an academic referral center. METHODS: Patients presenting with serous cystadenoma in the years 2000-2013 were selected. Hospital records were evaluated for patient and serous cystadenoma characteristics. RESULTS: A total of 22 patients with serous cystadenoma were identified. Mean age at diagnosis was 63 years and 82% were women. Diagnosis was incidental in 59%, and 18% presented with unspecific abdominal pain, 14% unexplained weight loss, 4.5% gastrointestinal obstructive symptoms, and 4.5% cholangitis. Location was pancreas body 36%, head 32%, tail 23%, and uncinate 9%. Mean serous cystadenoma diameter at diagnosis was 37 ± 23 mm. After diagnosis five patients underwent surgery. Initial size was similar between surgical and follow-up groups (p = 0.9). Four cases were lost to follow-up; 13 continued conservative management with a mean follow-up time of 54 ± 27 months. The initial and last serous cystadenoma size in the follow-up group remained similar (p = 0.9). Six cases presented significant tumor growth during follow-up (p > 0.05). All patients remained asymptomatic throughout follow-up. No malignancy or serous cystadenoma-related death occurred. CONCLUSIONS: Size change of serous cystadenoma was minimal and patients remained asymptomatic during follow-up. Surgery should be limited to symptomatic and selected cases.

RESUMO

Number of newly diagnosed cystic pancreatic tumors is permanently increasing. This fact is primarily related to the development of new diagnostic methods. The main representative ones are: serous cystadenoma, mucinous cystic neoplasm, intraductal papillary mucinous neoplasm and solid pseudopapillar tumor. Because of the malignant potential of these lesions, proper indication of surgical treatment is extremely important. The article highlights and describes our experience in diagnostics and therapy of cystic pancreatic tumors diagnosed in the General Teaching Hospital Prague in the period: 1/ 2008- 12/ 2012. All patients were investigated by computerised tomography and endoscopic ultrasound with fine -  needle aspiration biopsy. Thirty seven patients in total were diagnosed with cystic pancreatic tumors: 19 with serous cystadenoma, 5 with mucinous cystic neoplasm, 5 with mucinous cystadenocarcinoma, 5 with intraductal papillary mucinous neoplasm and 3 with solid pseudopapillar tumor. In 14 cases patients were indicated for surgery, in 1 case signs of malignant transformation were found. Determination of the optimal strategy for diagnostic and therapeutic procedures in patients with cystic pancreatic tumors requires the dia-gnosis, treatment and followup observation in adequately equiped specialized centers.

RESUMO

BACKGROUND AND AIMS: The natural history and growth pattern of pancreatic serous cystic neoplasms (SCNs) are not well understood. This study was designed in order to get insight into the growth rate of SCNs and to suggest recommendations for their management. METHODS: Patients with well-documented incidentally discovered or minimally symptomatic SCNs who underwent yearly surveillance MRI were analysed using a linear mixed model. The growth rate and the effects of different fixed factors (sex, personal history of other non-pancreatic malignancies, radiological pattern, clinical presentation, tumour site) and random factors (age and tumour diameter at the time of diagnosis) on tumour growth were investigated. RESULTS: Study population consisted of 145 patients. Estimated overall mean growth rate was 0.28 cm/year, but the growth curve analysis showed a different trend between the first 7 years after the baseline evaluation (growth rate of 0.1 cm/year) and the subsequent period (years 7 to 10, growth rate of 0.6 cm/year, p<0.0001). Tests for fixed effects demonstrated that an oligocystic/macrocystic pattern and a personal history of other tumours are significant predictors of a more rapid mean tumour growth (p<0.0001 and 0.022, growth rates of 0.34 cm/year). Furthermore, tumour growth significantly increased with age (p = 0.0001). CONCLUSION: Overall, SCNs grow slowly, and an initial non-operative approach is feasible in all the asymptomatic or minimally symptomatic patients. The oligocystic/macrocystic variant, a history of other non-pancreatic malignancies and patients' age impact on tumour growth. In any case, a significant growth is unlikely to occur before 7 years from the baseline evaluation. Tumour size at the time of diagnosis should not be used for decisional purposes.

RESUMO

A 73-year-old woman visited our hospital for a treatment of pancreatic tumor that increased steadily in size of 6 cm in diameter in 1999 to 13 cm in 2008, while remaining in asymptomatic condition throughout this follow-up time. The tumor was big and flowed from many vessels such as portal and superior mesenteric veins and the celiac and superior mesenteric arteries. These were critical for determining tumor respectability and the risk of massive intra-operative hemorrhage was felt to be considerable. Therefore, preoperative embolization of the tumor-feeding arteries arising from the celiac axis (gastroduodenal, splenic and dorsal pancreatic arteries) was performed on the previous day of operation. Tumor resection with pancreaticoduodenectomy and partial resection of portal vein and reconstruction were performed. We got to SMA with the use of "paraduodenal mesenteric approach", we called, and we finished the operation without a blood transfusion. The final pathology confirmed the diagnosis of serous microcystic adenoma.

RESUMO

RATIONALE: Gastric-type endocervical adenocarcinoma (GAS) is a rare type of cervical adenocarcinoma that is a mucinous adenocarcinoma with a variety of gastral patterns. To date, there are no systematic clinical diagnosis and treatment guidelines. PATIENT CONCERNS: In our case, a 49-year-old woman underwent pelvic magnetic resonance imaging (MRI) due to a pelvic mass, and cervical lesions were unexpectedly found. After receiving relevant surgical treatment, the pathological results showed the particularity of the tumor type-cervical gastric adenocarcinoma with a borderline serous tumor of both appendages and the right ovary. DIAGNOSES: Postoperative routine pathological examination showed mucoepithelial metaplasia accompanied by a borderline serous tumor. INTERVENTIONS: After gynecological/urinary ultrasound, blood tests, MRI, cervical biopsy, and uterine curettage, "robot-assisted laparoscopic radical hysterectomy + bilateral salpingectomy-ovariectomy + pelvic lymph node dissection + pelvic adhesiolysis" were performed. After the surgery, the patient was treated with radiotherapy and concurrent chemotherapy. OUTCOMES: After the operation, radiotherapy, and chemotherapy, the patient had no tumor recurrence and is still in good condition. LESSONS: The diagnosis of GAS is relatively difficult, its clinical manifestations lack specificity, and the pathogenesis has nothing to do with human papillomavirus infection. The patient was misdiagnosed with vaginitis at a local hospital. However, we found that MRI and pathological examination were helpful for the diagnosis of the disease. Although there are no relevant guidelines to explain the treatment principles of GAS, we believe that early surgery is conducive to the prognosis of the disease because GAS has a certain tolerance to radiotherapy and chemotherapy.

RESUMO

Estrogen and progestin are involved in ovarian carcinogenesis. Change in nm23-H1 expression and the PIK3/AKT pathway are involved in carcinogenesis, development, invasion and metastasis of ovarian cancers. Therefore, it is critical to understand the signaling pathways that regulate hormone-induced cell migration and invasion in ovarian cancer. We investigated nm23-H1, AKT and pAKT expression by using immunohistochemical staining in ovarian clear cell adenocarcinoma, ovarian benign, borderline and malignant serous tumors and analyzed their relationship with prognostic factors. Using ES-2 and SKOV-3 ovarian cancer cell lines, we studied the modulation of estrogen and progestin on cell migration and invasion as well as their effect on AKT, pAKT and nm23-H1 expression. Furthermore, the signaling pathways were examined using pharmacological inhibitors (LY294002 and PD98059) or AKT siRNA combined with estrogen or progestin in the two cell lines. Weak nm23-H1 and high AKT and pAKT expression was observed in ovarian serous adeno-carcinoma and ovarian clear cell adenocarcinoma. Our data demonstrated that the expression of nm23-H1 was negatively correlated with tumor stage and grade and lymph node metastasis, whereas the expression of AKT/pAKT was positively correlated with these clinic factors. Estrogen up-regulated pAKT expression and reduced nm23-H1 expression, which ultimately resulted in increased cell migration and invasion. In contrast, progestin reduced pAKT expression and increased nm23-H1 expression, which inhibited cell migration. PIK3 kinase inhibitor LY294002 antagonized the effect of estrogen. On the other hand, it reinforced the effect of progestin. Our data suggest that AKT and pAKT are unfavorable prognostic factors for ovarian serous adenocarcinoma and clear cell carcinomas whereas nm23-H1 expression predicates favorable patient prognosis. Estrogen down-regulates nm23-H1 expression and promotes cell migration and invasion by activating the PIK3/AKT pathway. Progestin has an opposing effect.

RESUMO

BACKGROUND/AIMS: Due to enhanced imaging modalities, pancreatic cysts are being increasingly detected, often as an incidental finding. They comprise a wide range of differing underlying pathologies from completely benign through premalignant to frankly malignant. The exact diagnostic and management pathway of these cysts remains problematic and this review attempts to provide an overview of the pathology underlying pancreatic cystic lesions and suggests appropriate methods of management. METHODS: A search was undertaken with a Pubmed database to identify all English articles using the keywords 'pancreatic cysts', 'serous cystadenoma', 'intraductal papillary mucinous tumour', 'pseudocysts', 'mucinous cystic neoplasm' and 'solid pseudopapillary tumour'. RESULTS: The mainstay of assessment of pancreatic cysts is cross-sectional imaging incorporating CT and MRI. Fine-needle aspiration (FNA) (often with endoscopic ultrasound) may provide valuable additional information but can lack sensitivity. Symptomatic cysts, increasing age and multilocular cysts (with a solid component and thick walls) are predictors of malignancy. A raised cyst aspirate CEA, CA 19-9 and mucin content (including abnormal cytology), if present, can accurately distinguish premalignant and malignant cysts from benign ones. CONCLUSION: In summary, all patients with pancreatic cystic lesions, whether asymptomatic or symptomatic, must be thoroughly investigated to ascertain the underlying nature of the cyst. Small asymptomatic cysts (<3 cm) with no suspicious features on imaging or FNA may be safely followed up. Follow-up should continue for at least 4 years, with a repeat FNA if needed. An algorithm for the management of pancreatic cystic tumours is also suggested. and IAP.

RESUMO

Serous cystadenoma of the pancreas is a diagnosis being entertained with increasing frequency. The histopathologic findings, diagnostic strategy, differential diagnosis, and treatment strategy of these generally benign but sometimes symptomatic lesions are discussed. Based on the available case series, surgical resection should be considered in good-risk patients with symptomatic tumors, with tumors at least 4 cm in maximum diameter, or in whom a more worrisome diagnosis cannot be excluded.

RESUMO

AIM: The ovarian cancer is the most malignant disease from all oncogynecological localizations. There are different scientific opinions whether the different histological types have different prognosis and survival. The aim of our research work was to evaluate if the endometrioid cancer of the ovary has a different prognosis from the serous ovarian cancer. METHODS: 84 patients were evaluated for five years period from 2003 till 2008. The patients with endometrioid ovarian cancer (42) were matched with the patients with serous ovarian cancer (42). They were matched for age, grading,stage, and level of cytoreduction. RESULTS: 84 patients (42 with endometrioid cancer and 42 with serous ovarian cancer) were evaluated for 5 years period. The five years survival of the patients with endometrioid ovarian cancer was 62% while the five years survival for patients with serous ovarian cancer was 72%. In patients with endometrioid ovarian cancer the mean survival rate was 58 months, and for patients with serous ovarian cancer 70 months (P=0.30). The estrogen receptor levels were not statistically significant between the two groups (P=0.110), while the progesteron receptor levels were statistically different (P<0.002). CONCLUSIONS: In patients with endometrioid and serous ovarian cancer, while taking into consideration the age, grading, stage and level of cytoreduction--there is no difference for the five years survival or the length of survival.

RESUMO

Pancreatic cystic lesions are a common clinical entity. The majority are neoplastic and have the potential for malignant transformation. To assist with patient management, a number of clinical guidelines have been developed over the past decade. However, controversies exist in regards to the various guidelines and treatment strategies they offer. This article will review the various clinical guidelines for management of pancreatic cysts, describe the limitations of these guidelines, and present future directions for improvement in clinical decision making for patients diagnosed with a pancreatic cystic neoplasm.

RESUMO

Pancreatic cystic neoplasms (PCNs) are being increasingly detected because of rapid advances in radiologic technology and an increased imaging demand. The management of PCNs is challenging as most of these neoplasms are asymptomatic, but have malignant potential, and surgical resection has substantial perioperative morbidity and mortality. Endoscopic ultrasonography (EUS)-guided ablation, as a minimally invasive treatment, has received increasing attention in the past few years. However, the resolution after EUS-guided ablative therapy still needs to be improved. In this case report, EUS-guided radiofrequency ablation combined with lauromacrogol ablation was applied for the first time in the treatment of PCN, and it showed complete resolution at a 3-month follow-up.

RESUMO

OBJECTIVE: The survival rate for the most common gynecologic cancer, endometrial cancer, has fallen significantly in the last 25 years. Stage III (International Federation of Gynecology and Obstetrics) disease accounts for most of the deaths. We evaluated prognostic factors, treatment-related survival, and routinely used assessments for identifying stage III disease before the operation. STUDY DESIGN: The data for patients with endometrial cancer stage III (n = 101) who had been treated at the McGill University Health Center between 1989 and 2003 were analyzed. RESULTS: Stage IIIA, IIIB, and IIIC tumors accounted for 63%, 4%, and 33% of the data, respectively. The cause-specific survival at 2, 3, and 5 years was 82%, 77%, and 67%, respectively. In multivariate analysis with an adjustment for the standard prognostic variables, the final tumor grade, adnexal involvement, and lymph node dissection were significant predictors of cause-specific survival (P = .001, .028, and .017, respectively). Of the preoperative investigations, an elevated CA-125 level was a significant predictor of cause-specific survival in multivariate analysis (P = .029). CONCLUSION: An elevated CA-125 level, adnexal involvement, the final tumor grade, and lymph node dissection were independent predictors for cause-specific survival.

RESUMO

Recently, there has been an increased recognition of neoplasms of the pancreas other than ductal adenocarcinoma. Although not as well studied or characterized as pancreatic adenocarcinoma there are many distinct lesions which exhibit diverse biological behaviors and varying degrees of malignancy. These lesions include: endocrine neoplasms, cystic tumors, solid pseudopapillary tumors, acinar cell carcinoma, squamous cell carcinoma, primary lymphoma of the pancreas, and metastatic lesions to the pancreas. These less common neoplasms are being diagnosed more frequently as the number and sensitivity of diagnostic imaging studies increase. This review article discusses the clinical course, diagnosis, and treatment of these less common, but quite relevant, neoplasms of the pancreas.

RESUMO

Hydatid disease (HD) is a commonly occurring zoonotic disease caused by tapeworms of the genus Echinococcus. It is endemic in many parts of the world and can involve almost any organ of the body. Although HD of the liver and lungs is quite common, ovarian involvement is rare. We present a case of a 24-year-old female patient who was diagnosed with multifocal hydatidosis involving the liver and bilateral ovaries on imaging. Postoperative histopathology confirmed the hydatid disease in the liver and one ovary. However, the cystic lesion in the other ovary turned out to be a borderline serous cystadenoma. This case highlights the limitation of imaging in differentiating between simple hydatid cysts and serous cystadenomas of the ovaries. Another point we learnt is that even in the presence of multifocal hydatidosis in endemic regions, serous cystadenoma needs to be considered in imaging differential diagnosis.
