Role of transvaginal ultrasound-guided biopsy in gynecology.

BACKGROUND: Ultrasound-guided biopsy is an easy technique for obtaining tissue samples. It is commonly used for different types of tumors, such as breast and prostate cancers, in order to plan early and adequate treatment. OBJECTIVE: To evaluate the indications, adequacy, and safety of transvaginal ultrasound-guided biopsy in women with pelvic lesions suspected of gynecologic malignancy. METHODS: A retrospective study including all patients who had undergone transvaginal ultrasound-guided biopsy between April 2015 and May 2018 was carried out at the division of gynecologic oncology. Inclusion criteria were the presence at imaging of abdominal or pelvic tumors in patients considered not ideal candidates for primary gynecological surgery, or the origin and/or nature of the tumor was unclear and further management required histological verification. Patients with planned surgery were excluded from the study. Transvaginal biopsies were performed with a 18 G/25 cm core-cut biopsy needle and histology was obtained. Tru-cut biopsies were performed using an automatic bioptic gun with a 18 G/25 cm core-cut biopsy needle. Results are presented as absolute frequency (percentage) for nominal variables and as median (range) for continuous variables. RESULTS: A total of 62 women were analyzed. An adequate sample for histological analysis was obtained in all cases. Histopathological examinations showed 24 (38.7%) benign lesions (fibrosis, inflammation, uterine or ovarian myoma) and 38 (61.3%) malignant tumors, distributed as follows: 34 (89.5%) malignant gynecological lesions and 4 (10.5%) non-gynecological malignant tumors. Among the malignant lesions, there were 12/38 (31.6%) primary tumors, 24/38 (63.2%) recurrent tumors, and 2/38 (5.3%) metastases from non-genital cancer. Ten patients eventually underwent surgery. Final histology was not in agreement with the results from transvaginal ultrasound-guided biopsy in 2 of 10 patients (20%); in particular, benign disease at transvaginal ultrasound-guided biopsy was malignant at final histology (two cases of recurrence of cervical cancer). Three patients (4.8%) had pain during the procedure, which was controlled by oral analgesic therapy and lasted for no longer than 10 min. No major complications were registered. CONCLUSIONS: Transvaginal ultrasound-guided biopsy is a minimally invasive method to obtain adequate material for histological diagnosis and could avoid unnecessary surgical procedures, costly CT-guided procedures, or prolonged waiting times.

Ultrasound features and clinical outcome of patients with malignant ovarian masses diagnosed during pregnancy: experience of a gynecological oncology ultrasound center.

OBJECTIVE: The number of women diagnosed with ovarian masses during pregnancy has increased in recent years and the management of these women can be controversial. We aim to describe ultrasound characteristics and clinical outcomes of patients with malignant ovarian masses diagnosed during pregnancy. METHODS: Patients with a histological diagnosis of malignant ovarian mass detected during pregnancy who underwent pre-operative ultrasound by experienced ultrasound examiners between December 2000 and November 2017 were included in this retrospective observational study. Ultrasound characteristics of the masses were described using International Ovarian Tumor Analysis terminology. Patients with ovarian masses but without histopathological reports were excluded. Results are presented as absolute frequency (percentage) for nominal variables and as median (range) for continuous variables. Results A total of 22 patients were included in the analysis. The median age was 32.5 (range 23-42) years and median gestational age at diagnosis was 13.5 (range 4-30) weeks. Eight (36.4%) patients had a serous/endocervical-type borderline tumor, seven (31.8%) patients had a primary epithelial ovarian carcinoma, five (22.8%) patients had a metastatic tumor to the ovary, and two (9%) patients had a mucinous borderline tumor. At ultrasound, mucinous borderline tumors were multilocular (1/2, 50%) or multilocular-solid (1/2, 50%) lesions. Serous/endocervical-type borderline tumors were unilocular-solid (3/8, 37.5%) or multilocular-solid (5/8, 62.5%) masses and all had papillary projections. Most invasive epithelial ovarian cancers were multilocular-solid masses (5/7, 71.4%). All metastatic tumors appeared as solid masses. No patients with borderline tumors had a cesarean section due to disease, whereas most patients with epithelial ovarian carcinomas (4/7, 57.2%) and with ovarian metastases (3/5, 60%) had a cesarean section due to disease. No neonatal complication was reported for patients with borderline tumors or epithelial ovarian carcinomas, whereas two of three newborns of patients with metastatic tumor died of the disease. CONCLUSION: At ultrasound, morphological features of malignant ovarian masses detected during pregnancy are similar to those described in non-pregnant patients. The likelihood of undergoing cesarean section increases with malignant disease in the ovary.

Role of ultrasound in advanced peritoneal malignancies.

INTRODUCTION: Ovarian cancer is the seventh most common cancer among women in the developed world, and most women with ovarian cancer are diagnosed at an advanced stage of disease, when large intraperitoneal dissemination has already occurred. An accurate preoperative assessment of the tumor dissemination is pivotal for adequate counseling among risks and benefits of an aggressive surgical procedure, often required to achieve a complete cytoreduction. When performed by an experienced sonographer, ultrasound has an invaluable role in the primary diagnosis of gynecological cancer, in the assessment of tumor extent in the pelvis and abdominal cavity; however, there is a paucity of data on its use in the evaluation of the extent of disease of such patients. EVIDENCE ACQUISITION: The search retrieved 208 articles in the best matching results list. Selection by abstract and full-text, yielded 15 publications that contained information on the role of ultrasound examination in the assessment of diffused peritoneal malignancies. EVIDENCE SYNTHESIS: Sonographic appearance of metastatic nodules in peritoneum and omentum were firstly analyzed in preliminar descriptive studies, together with a systematic method to scan the abdomen and pelvis in in the staging of diffused gynecological malignancies. To date, three prospective studies mainly focused on the specific role of ultrasound (without comparison with other imaging modalities) in the evaluation of intra-abdominal tumor extension in ovarian cancer patients. In these studies, authors were in agreement to conclude that ultrasound has a very reliable role in the staging of ovarian cancer. In particular, ultrasound examination showed a high sensitivity (range 81.4-91%) and specificity (range 88-96%) in the diagnosis of peritoneal carcinomatosis, as well as in omental involvement (sense 67-94%, specificity 90%). In a recent prospective study ultrasound shows similar accuracy of CT scan in the staging of ovarian cancer patients (71% vs. 75%) when compared with surgical results. CONCLUSIONS: Even if ultrasound is a largely diffuse and practice imaging technique, there is a paucity of data in literature on its use in the evaluation of the extent of disease in ovarian cancer patiens. Nevertheless, this review has demonstrated that ultrasound has a high accuracy in staging advanced ovarian cancer patients. In certain settings, ultrasound has already replaced CT scan in the pre-operative evaluation of pelvic and abdominal disease. Finally, ultrasound allows to perform a biopsy in patients with peritoneal carcinomatosis obtaining an adequate specimen for histologic diagnosis.

Laparoscopy vs. laparotomy for advanced ovarian cancer: a systematic review of the literature.

INTRODUCTION: In the last decade, laparoscopy has been progressively introduced in the management of advanced-stage ovarian cancer (AOC) to evaluate tumor resectability, avoiding an explorative laparotomy, to identify non-responders to submit to second-line chemotherapy and to perform primary or interval minimally invasive debulking surgery in selected patients. This review aims to deeply focus on the differences between laparoscopy and laparotomy in the management of advanced ovarian cancer. EVIDENCE ACQUISITION: The electronic database search provided a total of 80 results. Out of these, 63 results were excluded because considered not relevant to the review, for linguistic reasons or case reports. A total of 17 articles were considered eligible for the review. EVIDENCE SYNTHESIS: Many studies have assessed the value of laparoscopy in predicting the optimal resectability of AOC patients avoiding exploratory laparotomies. More recently, its role in primary and interval cytoreduction has been investigated for selected patients in terms of safety, feasibility and oncological outcomes. Published data are comparable to the standard laparotomic management in terms of oncological outcomes but with improved perioperative and psychological results. The selection of patients is crucial to perform a successful surgery. CONCLUSIONS: To date, laparoscopy has replaced the primary laparotomic approach in the evaluation of optimal resectability. As far as primary and interval minimally invasive debulking surgery are concerned, instead, most of the works report an overlap of oncological outcomes compared to traditional surgery. The selection of patients is a crucial point to reach a successful minimally invasive surgical treatment, taking into account surgical complexity and surgical adequacy.

Needleoscopic Conservative Staging of Borderline Ovarian Tumor.

STUDY OBJECTIVE: To investigate the safety and technical feasibility of needleoscopic fertility-sparing staging of borderline ovarian tumors. DESIGN: Video article and review of the literature (Canadian Task Force classification Level III). SETTING: This 29-year-old woman had a right ovarian cyst suspicious for borderline ovarian tumor on preoperative magnetic resonance imaging and ultrasound showing the presence of a right unilocular ovarian cyst with a papillary projection. Informed consent for abdominal or laparoscopic approach was obtained from the patient in accordance with the local legislation. The patient also provided informed consent to use images and videos of the procedure. Institutional Review Board approval was not required for this kind of procedure. INTERVENTIONS: Treatment involved conservative staging with right ovarian cystectomy, peritoneal biopsies, infracolic omental biopsy, and peritoneal cytology. Instrumentation included two 2.4-mm needleoscopic instruments. The total operative time was 62 minutes, and estimated blood loss was <10 mL. No intraoperative complications were recorded. At the end of the surgical procedure, the outer diameter of the incision was increased by only up to 3 mm. The patient was discharged the day after the procedure. Histopathological analysis confirmed a serous borderline ovarian tumor. A 30 days postoperative follow-up, a satisfactory cosmetic result was reported by both the patient (score of 10 of out of a possible 10) and the surgeon (10 of 10). CONCLUSION: To the best of our knowledge, there are no previously published reports of needleoscopic treatment of borderline ovarian tumor, which represents a great challenge for ultra-minimally invasive approaches [1-3]. Based on our initial experience, the needleoscopic instruments could prove to be a beneficial tool in adnexal benign or borderline disease. At present, only a hybrid operative setting should be considered to overcome the lack of bipolar energy [4-6]. Further studies are needed to define the benefits, advantages, and costs of this novel approach.

Imaging techniques for the evaluation of cervical cancer.

Improvements in the treatment of cervical carcinoma have made it possible to offer optimal and personalised treatment. Cervical cancer staging is based on clinical examination and histological findings. Many diagnostic methods are used in clinical practice. Magnetic resonance imaging is considered the optimal method for staging cervical carcinoma because of its high accuracy in assessing local extension of disease and distant metastases. Ultrasound has gained increased attention in recent years; it is faster, cheaper, and more widely available than other imaging techniques, and is highly accurate in detecting tumour presence and evaluating local extension of disease. Magnetic resonance imaging and ultrasound are often used together with computed tomography or positron emission tomography combined with computed tomography to assess the whole body, a more accurate detection of pathological lymph nodes and metabolic information of the disease.
