Imaging Evaluation of Ovarian Masses RadioGraphic

  1. Ovarian tumors can be categorized as epithelial, germ cell, sex cord-stromal, or metastatic. Epithelial tumors are the most common histopathologic type of malignant ovarian tumor (85% of cases) (, Fig 1) (, 5 6). Subtypes of epithelial tumors include serous, mucinous, endometrioid, clear cell, and Brenner tumors
  2. ant or specific imaging features may be present in some types of ovarian tumors
  3. The ovarian tumors can be divided in to three major categories— surface epithelial-stromal tumors, sex cord-stromal tumors, and germ cell tumors—according to the anatomic structures from which they arise. Each category is further divided into subtypes
  4. Ovarian malignant germ cell tumors (OMGCTs) are heterogeneous tumors that are derived from the primitive germ cells of the embryonic gonad

There are three main types of ovarian tumors: Epithelial tumors - derived from the cells on the surface of the ovary. This is the most common form of ovarian cancer and occurs primarily in adults. Germ cell tumors - derived from the egg producing cells within the body of the ovary Most tumors of the ovary can be placed into one of three major categories— surface epithelial-stromal tumors, sex cord-stromal tumors, and germ cell tumors (Fig. 1)—according to the anatomic structures from which the tumors presumably originate. Each category includes a number of subtypes The International Ovarian Tumor Analysis (IOTA) group ultrasound rules for ovarian masses are a simple set of ultrasound findings that classify ovarian masses into benign, malignant or inconclusive masses Sohaib SA, Reznek RH (2007) MR imaging in ovarian cancer.

  2. Ovarian serous neoplasms are the commonest of four general types of the epithelial ovarian tumors, and are more prevalent than the mucinous ovarian tumors.. Serous ovarian neoplasms are subdivided into benign, borderline, and malignant lesions according to their malignant potential and clinical behavior (see Pathology - Classification section below)
  3. Ovarian neoplasms range from benign to malignant and may be primary or secondary. Usually, they are classified by tissue of origin (surface epithelial, germ cell and sex-cord stromal) and metastatic (one secondary) (Table 1)
  4. Ovarian Malignant Germ Cell Tumors: Cellular Classification and Clinical and Imaging Features1 Ovarian malignant germ cell tumors (OMGCTs) are heteroge-neous tumors that are derived from the primitive germ cells of the embryonic gonad. OMGCTs are rare, accounting for about 2.6% of all ovarian malignancies, and typically manifest in adolescence
  5. Ovarian cancer is the second most common of all gynecologic malignancies. It is the leading cause of death in this category of diseases, frequently presenting as a complex cystic mass. The finding of an adnexal cyst causes considerable anxiety in women due to the fear of malignancy
  6. Ovarian epithelial tumors account for the majority of all ovarian tumors (60-70%) and their malignant forms represent >90% of ovarian cancers 1. They can range from being benign to highly malignant

  5. Borderline tumors fall under ovarian epithelial tumors. They tend to develop in an exophytic growth pattern, on the surface of the ovary, without invading the underlying stroma. Papillary projections are characteristic and may be more of a feature with borderline than malignant serous cystadenocarcinoma of the ovary
  6. Background: Diagnosis of secondary ovarian tumors originating from colorectal cancer has previously been based upon history of malignancy and radiological findings of bilateral masses with a stained glass appearance. The purpose of this study was to perform a detailed investigation of the radiological and macroscopic features of ovarian metastases originating from colorectal cancer, which.
  7. Dr. Balachandran is an Assistant Professor and Dr. Iyer is an Associate Professor, Department of Diagnostic Imaging, UT MD Anderson Cancer Center, Houston, TX.. Ovarian cancer is the second most common gynecologic malignancy and is the fifth leading cause of cancer death in women. 1 Nearly 75% of women with ovarian cancer present with advanced stage disease, which is associated with a poor.

Ovarian teratomas are the most common type of germ cell tumors. There are three major subtypes of ovarian teratomas including mature, immature, and monodermal teratomas. Ultrasound, computed tomography and magnetic resonance imaging can demonstrate specific imaging findings for mature teratoma Overall, however, the imaging features overlap with both benign and malignant ovarian tumors. Despite this, it is important for the radiologist to be familiar with the imaging appearances of borderline tumors because they can present in younger patients and may benefit from different clinical/surgical management Example of discordant classification by classification according to Society of Radiologists in Ultrasound (SRU) criteria and International Ovarian Tumor Analysis (IOTA) simple rules. Cyst was classified as indeterminate at imaging according to SRU criteria because of papillary projections along posterior wall that did not have any Doppler flow. 25.

Ovarian Cancer •Only a minority of the frequently encountered adnexal masses in clinical practice are malignant •5% -10% of women undergo surgery and only 13% - 21% have ovarian carcinoma NIH Consensus Conference. Ovarian cancer. Screening, treatment, and follow-up. NIH Consensus Development Panel on Ovarian Cancer JAMA 199 The results showed that the new classification of ovarian tumor has a better method. The diagnostic accurate rate is 90.9%. In addition, we described the characteristic feature of five groups of ovarian tumors by sonography and discussed the role in early diagnosis of malignant ovarian tumors and improvement five year survival rate Histologic Tumor Grading. Independent of tumor stage, tumor grade is an important predictor of disease outcome with higher grade tumors behaving more aggressively. Grade is usually based on microscopic features, including nuclear features. The more closely the tumor resembles normal tissue, the lower the tumor grade and the less aggressive it will behave Tumors were classified according to the World Health Organization International Classification of Ovarian Tumors . Borderline tumors were defined as malignant in the present study since patients with borderline epithelial tumors have the same surgical intervention as malignant ovarian tumors [ 22 ] Precise histological classification of epithelial ovarian cancer (EOC) has immanent diagnostic and therapeutic consequences, but remains challenging in histological routine. The aim of this pilot study is to examine the potential of matrix‐assisted laser desorption/ionization (MALDI) imaging mass spectrometry in combination with machine.

blood. Many women with ovarian cancer have high levels of CA-125. This test can be useful as a tumor marker to help guide treatment in women known to have ovarian cancer, because a high level often goes down if treatment is working. But checking CA-125 levels has not been found to be as useful as a screening test for ovarian cancer IntroductionMolecular pathological research has contributed to improving the knowledge of different subtypes of ovarian cancer. In parallel with the implementation of the new FIGO staging classification, the WHO classification was revised. The latter is mainly based on the histopathological findings and defines the actual type of tumor. It has, therefore, also an important impact on prognosis. In ovarian cancer MALDI‐Imaging studies have been concerned to individual single markers distinguishing stroma and tumor tissue. 36 They indicate tumor characteristics such as proliferation or modulation of immune response. 37 Furthermore, Meding et al. demonstrate that tryptic peptide datasets generated by complementary liquid chromatography. Epithelial tumors represent 60% of all ovarian tumors and 85% of malignant tumors .They originate from the surface epithelium of the ovary. Their classification depends both on the cell type of the epithelium, of which there are five (serous, mucinous, endometrioid, clear cell and Brenner cell), and on the histological degree of malignancy (benign, borderline and malignant) 20% of all benign ovarian tumors. Women usually between 20 - 60 years. Present clinically as cystic adnexal masses. Increasing abdominal girth. 15% are bilateral. Imaging findings. Average 5-10cm (frequently grow larger) May be indistinguishable from simple cysts. Or they may have thin septations and occasionally papillary projections

Ovarian masses present a special diagnostic challenge when imaging findings cannot be categorized into benign or malignant pathology. Ultrasonography (US), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) are currently used to evaluate ovarian tumors. US is the first-line imaging investigation for suspected adnexal masses. Color Doppler US helps the diagnosis identifying. Ovarian cancer is the most frequent cause of death from gynaecological malignancy 1 and in the UK there were 7,116 new cases diagnosed in 2011.1 There has been a 56% increase in the incidence of ovarian cancer in women aged 15- 39 since the mid-1970s.1 Neoplasms of surface epithelial origin account for 90% of malignant ovarian tumours, most.

Imaging ovarian cancer. Clinical features of imaging techniques are described in Table 1. Ultrasound imaging. Pelvic transvaginal sonography (TVS) together with abdominal and pelvic transabdominal sonography is the most important procedure for the morphological evaluation of OC with the use of the Doppler and color Doppler to study mass. The ovaries are mainly made of three types of cells, and each type can develop into a different type of tumor. Epithelial tumors- These tumors start from cells that cover the surface of the ovary. Epithelial tumors account for nearly 85%-90% of all ovarian malignancies. 5. Germ cell tumors- These tumors start from the cells that produce the eggs Ovarian cancer treatments may also cause side effects, such as nausea, constipation, diarrhea, fatigue, and weight loss. Types of Ovarian Cancer. Because there are many types of cells that make up the ovary, there are many types of ovarian cancer. Tumors may form from any of the three main ovarian cell types This is based on the results of a physical exam, biopsy, and imaging tests done before surgery. For more information see Cancer Staging. The system described below is the most recent AJCC system effective January 2018. It is the staging system for ovarian cancer, fallopian tube cancer, and primary peritoneal cancer

Leg swelling. Diagnosis of ovarian cancer often begins with a pelvic exam, blood tests and a transvaginal ultrasound, an imaging procedure used to detect tumors in the ovaries. Often at CT scan follows to evaluate the entire abdominal cavity. If cancer is suspected, a surgical biopsy of the tumor, needle aspiration to remove fluid, or surgery. Despite the correlation of clinical outcome and molecular subtypes of high-grade serous ovarian cancer (HGSOC), contemporary gene expression signatures have not been implemented in clinical practice to stratify patients for targeted therapy. Hence, we aimed to examine the potential of unsupervised matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) to stratify. High-grade serous ovarian cancer (HGSOC) is the most common histological subtype of ovarian cancer to be diagnosed clinically. Due to a lack of adequate early-stage detection, HGSOC accounts for a majority of ovarian cancer-related deaths [].Treatment with platinum-based chemotherapy following primary debulking surgery will initially lead to a complete response in most patients Type I and type II tumors in ovarian carcinoma.

Over the past decade, medical imaging has played an increasingly valuable role in the diagnosis, staging, and treatment planning of the disease. In this Focus on Molecular Imaging review, we seek to provide a brief yet informative survey of the current state of the.

Low-grade serous carcinoma (LGSC) is an infrequent subtype of ovarian cancer, corresponding to 5% of epithelial neoplasms. This subtype of ovarian carcinoma characteristically has molecular features, pathogenesis, clinical behaviour, sensitivity to chemotherapy, and prognosis distinct to high-grade serous carcinoma (HGSC). Knowing the difference between LGSC and other ovarian serous tumours is. Ovarian Leydig cell tumors have been divided into two subtypes by some pathologists, the hilus cell tumor and the Leydig cell tumor, nonhilar type. The former, which is much more common, originates in the ovarian hilus from hilar Leydig cells, which have been identified in 80-85% of adult ovaries Ovarian cancer is one of the most common gynecologic malignancies. Accurate classification of ovarian cancer types (serous carcinoma, mucous carcinoma, endometrioid carcinoma, transparent cell carcinoma) is an essential part in the different diagnosis. Computer-aided diagnosis (CADx) can provide useful advice for pathologists to determine the diagnosis correctly 0:00 / 2:27. Live. •. The nationally renowned gynecologic oncology program at Siteman Cancer Center is the largest in the Midwest. Beyond our gynecologic cancer physicians, our team includes radiation oncologists, pathologists, nurses, a psychologist, a social worker and genetic counselors. These specialists meet weekly to discuss patient. Other imaging tests - such as chest X-rays, magnetic resonance imaging (MRIs) or colonoscopies - may be used to determine if ovarian cancer has spread. Blood tests. Elevated levels of certain tumor markers may be present in the blood of ovarian cancer patients. CA-125 is a protein that is often found on the surface of ovarian cancer cells

Ovarian cancer is the most common cause of cancer death from gynecologic tumors in the United States. Around the world, more than 200,000 women are estimated to develop ovarian cancer every year and about 100,000 die from the disease. The lifetime risk of a woman developing epithelial ovarian cancer is 1 in 70 Even though the test performance of any biochemical or radiological diagnostic test appears to increase after excluding borderline ovarian tumors and non-gynecological primary tumors, such as of the gastrointestinal tract or breast, we included in our literature assessment studies addressing all types of adnexal tumor, as this is a better. In a recent meta-analysis studying borderline or malignant ovarian cancer vs. benign ovarian lesions, the pooled likelihood ratio for the occurrence of a positive MRI result was 6.6 (95% CI: 4.7-9.2) and the post-test probability for borderline or malignant diagnosis was 77% (95% CI: 70-82) . The specificity in our study is low (52%), as all.

  2. Introduction. Early detection and characterization of ovarian lesions is of utmost importance for adequate management (1,2).Ovarian cancer accounts for 3.3% of all cancers in women worldwide but has only a 5% of female cancer deaths because of low survival rates ().Its late detection, due to the fact that early ovarian cancer is usually asymptomatic, causes advance disease and high mortality.
  3. A rare form of ovarian tumor that develops in the connective tissue cells, called granulosa and theca cells, that hold the ovaries together. Over 90% of these stromal tumors are called granulosa cell tumors; the other types are Sertoli-Leydig cell tumors and steroid cell tumors. Fallopian tube cancer. We now know that most cancers previously.

Diagnostic Tests. To help diagnose ovarian cancer, our doctors may order imaging tests and blood tests. If ovarian cancer is suspected, our doctor may also perform a biopsy—the removal of tissue for examination under a microscope for signs of cancer—during surgery. Rarely, another type of biopsy called a needle or core biopsy may be necessary The 2014 WHO Classification of ovarian neoplasms introduced a new entity of seromucinous tumors associated with endometriosis. These tumors encompassed a spectrum from benign to malignant and included seromucinous cystadenoma/ cystadenofibroma, seromucinous borderline tumor/atypical proliferative seromucinous tumor and seromucinous carcinoma Adnexal masses are common, resulting in a significant clinical workload related to diagnostic imaging, surgery, and pathology. 1,2 Most adnexal masses are benign, and most masses can be accurately categorized as benign or malignant on ultrasonography. 3,4 However, between 18% and 31% of adnexal masses remain indeterminate following.

Introduction. Ovarian cancer is the sixth most common tumour in women. More than 200,000 new cases are diagnosed each year worldwide. Each year, it constitutes 4% of all cancers diagnosed in women, and there are 6.6 new cases per 100,000 women per year [1, 2].Its history has been known scientifically for over 150 years; during this time, its mortality rate has not changed but its incidence has. Epithelial ovarian cancer (EOC) is the most common histo-logical type of ovarian cancer and accounts for 90% of them.1 The histological types of ovarian cancer arising from sex cord stromal cells and germ cells account for the rest. Among the EOC, high-grade serous ovarian carcinomas account for 70 to 80% and present with late stage disease Ovarian germ cell tumor is a disease in which malignant (cancer) cells form in the germ (egg) cells of the ovary. Germ cell tumors begin in the reproductive cells (egg or sperm) of the body. Ovarian germ cell tumors usually occur in teenage girls or young women and most often affect just one ovary. The ovaries are a pair of organs in the female.

  1. Ovarian tumors represent a remarkably heterogeneous group of benign, borderline, and malignant neoplasms that usually result in significant diagnostic challenges to radiologists, surgeons, and pathologists [1-3].The preoperative qualitative diagnosis and accurate characterization of ovarian tumors are the key steps for an optimal clinical treatment strategy, which is also helpful for.
  2. Ovarian teratomas are a rare type of tumor in the ovaries that are made up of developed tissues and organs such as the hair, teeth, muscle, and bone.When viewed under a microscope, ovarian teratomas look like three layers of a developing embryo. Teratomas can occur in newborns, children, and adults and are most common in women in their 20s
  3.

Reference Image-Guided Percutaneous Thermal Ablation of Oligometastatic Ovarian and Non-Ovarian Gynecologic Tumors
  4. Researchers at MIT and Massachusetts General Hospital have developed a way to improve the accuracy of surgery to remove ovarian tumors. Using carbon nanotubes and a near-infrared imaging system, they could find and remove tumors as small as 0.3 millimeters during surgery in mice, resulting in a 40 percent enhancement in median survival
  5. The type of treatment recommended depends on the location and stage of the cancer. Below are standard treatments currently used. Surgery: Surgery to remove the cancer is the most common treatment for ovarian germ cell tumors. One ovary and fallopian tube may be removed in a procedure called unilateral salpingo-oophorectomy.More invasive cases may require a total hysterectomy, to remove the.
  6. For example, imaging tests can show if the cancer has spread. Imaging tests show pictures of the inside of the body. Doctors may also do tests to learn which treatments could work best. For most types of cancer, a biopsy is the only sure way for the doctor to know if an area of the body has cancer. In a biopsy, the doctor takes a small sample.

The ovarian cancer surgery team at MSK is the nation's only group dedicated solely to the surgical treatment of all types and stages of ovarian cancer. Due to our expertise in radical debulking surgery, more than 90 percent of the women undergoing surgery for ovarian cancer at MSK have very little tumor remaining after the procedure Ovarian cancer is when cancer cells start and grow in the ovaries. The ovaries make eggs for reproduction and female hormones. There are different types of ovarian cancer. They include: Epithelial— the most common, found on the surface of the ovary. Germ cell tumors—from the reproductive cells. Stromal cancers—rare, from the connective cells CT of the abdomen and pelvis is the first line imaging modality for staging, selecting treatment options and assessing disease response in ovarian cancer. The staging CT provides disease distribution, disease burden and is the imaging surrogate for surgico-pathological FIGO staging. Optimal cyto-reductive surgery offers patients' the best chance for disease control or cure, but sub-optimal.

2. Histological Classification of Ovarian Carcinoma. EOC represents a group of heterogeneous disease entities. Five major categories of EOC exist, with differing cellular origins, hereditary implications, molecular alterations and potential for targeted therapies (Figure 1). In general, to promote consistency and uniformity, pathology review by. Types of Ovarian Cancer. Ovarian tumors can originate from different ovarian cell populations with different pathological characteristics.Therefore, understanding the ovary's microscopic anatomy is essential to understanding ovarian tumors. The ovary comprises the three main entities, made up of varying cells, which give rise to the various types of tumors

A simple blood test to measure the level of the CA-125 protein can be helpful in making a diagnosis. This tumor marker can in some cases indicate the presence of ovarian cancer, since most epithelial ovarian cancer cells release this protein. However, because other types of tissue including non-cancerous tissues can also raise the level of this protein, the test isn't usually recommended for. The prediction of non-resectability based on abdominal markers in ovarian cancer patients was based on the criteria defined by local guidelines. Results. Sixty-seven patients with ovarian cancer were enrolled between March 2016 and October 2017. In 67 patients, 51 (76%) had advanced and 16 (24%) had early stage ovarian cancer Most staging systems include information about: Where the tumor is located in the body. The cell type (such as, adenocarcinoma or squamous cell carcinoma) The size of the tumor. Whether the cancer has spread to nearby lymph nodes. Whether the cancer has spread to a different part of the body. Tumor grade, which refers to how abnormal the cancer. Epithelial ovarian cancer is the commonest cause of gynaecological cancer-associated death. The disease typically presents in postmenopausal women, with a few months of abdominal pain and distension. Most women have advanced disease (International Federation of Gynecology and Obstetrics [FIGO] stage III), for which the standard of care remains surgery and platinum-based cytotoxic chemotherapy Ovarian Stromal Tumors. These types of tumors are often diagnosed earlier than others. The most common subtypes are granulosa-theca tumors and Sertoli-Leydig cell tumors.Both are rare. Another.

Ovarian Cancer Pancreatic Cancer Prostate Cancer Skin Cancer Testicular Cancer Thyroid Cancer View Mor In the United States, ovarian cancer is the eighth most common cancer among women, according to the Centers for Disease Control and Prevention (CDC). While there are more than 30 types of ovarian cancer, all begin in one or both ovaries, or in the nearby fallopian tubes or peritoneum (the tissue that covers organs in the abdomen) If you are at a high risk for ovarian cancer, or showing signs of ovarian cancer, we may recommend the following tests to help determine if you have ovarian cancer: . Transvaginal sonography. An ultrasound performed with a small instrument that is placed in the vagina. CA-125 blood test. A blood test to determine if the level of a tumor marker called CA-125 has increased in your blood MRI for the evaluation of ovarian cysts is usually ordered with contrast, unless contraindicated. 8 In one study of MRI as second-line imaging for indeterminate cysts, contrast-enhanced MRI contributed to a greater change in the probability of ovarian cancer compared with computed tomography (CT), Doppler ultrasound, or MRI without contrast. 12.

Most ovarian cancer patients with advanced disease who are responding to six to eight cycles of chemotherapy, have a normal physical exam, a normal CA125 and a normal CT scan, will be followed by our team with an appointment every three months for the first two to three years Accurate predictions of ovarian cancer outcome possible with new classification system. The new, Oxford-developed method for subtyping ovarian cancer has been validated in a recent collaboration.

Ovarian cancer can be a frightening diagnosis, with five-year relative survival rates that range from 93% to 19% for epithelial ovarian cancer, depending on the stage when the cancer was found Ovarian cancer is a common gynecological malignancy and often diagnosed late with extensive peritoneal and nodal metastasis. Diffusion-weighted imaging (DWI) provides valuable information about the structural properties of the tissue and has shown great value in cancer imaging. Recently developed post-processing three-dimensional apparent diffusion coefficient (3D ADC) map has a significant. For all types of ovarian cancer taken together, about 3 in 4 (72.4%) women with ovarian cancer live for at least 1 year after diagnosis. Almost half (46.2%) of women with ovarian cancer are still alive at least 5 years after diagnosis. Women diagnosed when they are younger than 65 do better than older women

MRI classification and characterization of complex ovarian

Ovarian cancers (OC) include a group of diseases with variable prognoses. While most conventional imaging techniques rely on the detection of tumour burden and distant spread to identify treatment plans, more emphasis is now being placed on screening for early detection and also for more accurate staging using molecular imaging techniques. It is generally accepted that there are some. The American Cancer Society estimates that approximately 22,240 new cases of ovarian cancer are diagnosed in the United States annually. It is the ninth most common cancer among women and is the fifth leading cause of cancer deaths among women. Risk factors include: Being a woman over the age of 40. Being obese We have developed a coregistered photoacoustic and ultrasound (PAT/US) system and imaging probe for noninvasive transvaginal imaging of human ovaries, 16 - 19 and photoacoustic feature-based classification algorithms for differentiating malignant from benign ex vivo ovarian tissues. 20, 21 To overcome the challenges of light delivery and.

The European Society of Gynaecological Oncology (ESGO), the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG), the International Ovarian Tumour Analysis (IOTA) group, and the European Society for Gynaecological Endoscopy (ESGE) jointly developed clinically relevant and evidence-based statements on the pre-operative diagnosis of ovarian tumors, including imaging. Ovarian cancer is most common in older women. The average age for an ovarian cancer diagnosis is 63. Early stage ovarian cancer rarely shows symptoms, but there are some early signs and common. Ovarian tumors account for one percent of all malignant tumors found in children between birth and age 17. In girls younger than eight, four out of five ovarian tumors are benign (noncancerous). Ovarian tumors are different from ovarian cysts. Tumors are solid masses of tissue, while cysts contain fluid, tissues, or other materials

With 21,750 new diagnoses each year and an estimated 13,940 deaths expected in 2020, ovarian cancer ranks fifth in cancer deaths among women, accounting for more deaths than any other cancer of the female reproductive system. Below we dive into the types of ovarian cancer, what causes them and what symptoms to look out for. Ovarian Continue Knowing that ovarian cancer is one of the most difficult types of cancer to treat, researchers at the Massachusetts Institute of Technology (MIT; Cambridge, MA), working with surgeons and oncologists at Massachusetts General Hospital (MGH; Boston, MA), have developed a way to improve the accuracy of ovarian cancer surgery (debulking). Using a fluorescence imaging system, they were able to find. Blood flow to the ovary can also be visualized on ultrasound, which can help with the diagnosis. Other imaging, such as a CT scan or MRI, may be useful as well. The main concern with adnexal masses is whether or not they are malignant. A tumor marker called CA-125 is ordered if suspicion for ovarian cancer is high The workup for ovarian cancer includes Hematological (blood tests), biopsy and imaging studies for diagnosis and proper staging of cancer. Hematological tests. The blood tests in the setting of ovarian cancer include routine blood investigations (CBC, LFT, RFT, Serum Electrolytes) and test for tumor markers (CA-125, AFP, LDH, beta HCG, etc. Multispectral fluorescence imaging (MFI) has recently become a favorable method for cancer characterization. By utilizing MFI along with a characterized ovarian cancer mouse model and human fallopian tube histology sections, we were able to study cancer in its earliest stages with a promising modality for early disease detection Ovarian cancer is highly prevalent among European women, and is the leading cause of gynaecological cancer death. Current histopathological diagnoses of tumour severity are based on interpretation.
