Aim To determine the role of scrape cytology in the diagnosis of ovarian neoplasm Material and method This was a prospective study at jlnmc duration of study was from nov 2019 to march 2020 on 100 solid/solid-cystic ovarian neoplasms sent in 10% buffered formalin, then stained with hematoxylin and eosin or Papanicolaou stains. Cytological results were compared with the histological diagnosis taking the latter as the gold standard. Result Among the 100 cases, the standard histopathological diagnosis confirmed 61 as benign, 5 as borderline and 34 as malignant lesion. The diagnostic concordance between cytological and histo pathological study was observed in 97 of the 100 cases. Characteristic cytological pattern was noted in various types of surface epithelial, sex cord stromal and germ cell tumors. The technique had limited value in mucinous tumors to distinguish borderline cases from invasive carcinoma. Conclusions IOC is a good complement to histopathology in the study of ovarian neoplasms, particularly in developing countries like ours, where the facility of frozen sections is often not available. Adequate knowledge on cyto-histological correlation of ovarian scrape cytology may phase out the use of cryostat in intraoperative diagnosis of ovarian neoplasms.

Primary ovarian neoplasms constitute a heterogenous group of benign and malignant tumors of epithelial, sex cord–stromal, mesenchymal and germ cell origin. Secondary tumors constitute a minority. The management of benign and malignant ovarian neoplasms varies and it is here that imprint cytology plays a crucial role in diagnosis. It provides a rapid intraoperative diagnosis which will decide further treatment course for the patient. Imprint cytology of ovarian neoplasms is simple, inexpensive, challenging and provides a rapid diagnosis with excellent cellular details. The aim of the present study is to determine the role of imprint cytology in the diagnosis of ovarian neoplasms. A retrospective study was conducted in the department of pathology. A total of 53 cases were included in the study. In 48 cases, the imprint cytology findings correlated with the histopathological diagnosis. 5 cases did not correlate. Epithelial ovarian tumors accounted for the majority, (85%) followed by germ cell tumors (9.4%) and sex cord stromal tumors (5.6%). The sensitivity and specificity were 93.75% and 100% respectively. Thus imprint cytology is an effective cytological method in the diagnosis of ovarian neoplasms. Knowledge of specific cytological features for each tumor type helps in accurate diagnosis which in turn is valuable in immediate appropriate treatment and management of patients with benign or malignant neoplasms.

Aims: To assess the adequacy of intraoperative scrape cytology during percutaneous vertebroplasty by correlating results with corresponding histopathology. Settings and Design: Vertebroplasty is a procedure increasingly used to treat painful vertebral compression fractures. The history and presentation of osteoporotic fractures are straightforward, but difficulty arises in differentiating infective from neoplastic lesions, especially in cases where the magnetic resonance imaging is equivocal. The procedure involves injection of polymethyl methacrylate (bone cement) into the pathological vertebral body and gives dramatic pain relief. It is indicated in osteoporotic and neoplastic lesions but contraindicated in infections. Hence, intraoperative evaluation of a specimen is essential to aid in the decision of performing vertebroplasty. Subjects and Methods: A total of 128 patients with vertebral lesions underwent core biopsy and scrape cytology from June 2006 to June 2015. Based on the findings of cytological examination, malignant lesions were subjected to vertebroplasty. In lesions with infective etiology, vertebroplasty was abandoned and antibiotic or antituberculous therapy started. Results: The overall diagnostic accuracy of scrape cytology was excellent with 97.58% cases correlating with the final histopathological diagnosis. Specificity was 100%, positive predictive value was 100% and negative predictive value was 33.33%. Conclusion: Scrape cytology is a simple, rapid, accurate cytodiagnostic technique and should be routinely utilized in vertebral lesions for intraoperative consultation and decision making during vertebroplasty.

Background: Touch/ imprint cytology has been utilized for intraoperative evaluations of tumors to complement frozen sections in order to reach diagnosis prior to histopathology diagnosis. The main aim of this study is to find role of touch imprint in determining histopathology diagnosis of ovarian neoplasm. Materials and Methods: All together one hundred three cases were evaluated using both touch/imprint and histopathology diagnosis. The histopathology diagnoses consisted of Benign (n=85), borderline (n=4), and malignant (n=12). Touch imprint cytology consists of Negative for malignancy (n=90), Positive for malignancy (n=11) and inadequate (n=2). Inadequate smear was excluded from the study. Results: Both touch / imprint cytology were able to diagnose benign and malignant ovarian neoplasm. Out of 103 cases, in cytology showed 89.1% patients were negative and 10.9% patients were positive. Histopathology shows 84.2% of benign ovarian neoplasm, 3.9% borderline neoplasm and 11.9% of malignant. Diagnostic accuracy of touch/ imprint was 99% with sensitivity 100% and specificity was 91.67%. Positive predictive value was 98.89% and negative predictive value was 100%. Conclusion: Touch/ imprint cytology examination is simple, rapid and useful test in evaluation of ovarian neoplasms. It plays very important role in preliminary intraoperative diagnosis of benign and malignant ovarian neoplasms.

Background: Ovarian neoplasms are a distinct entity in women health care and are increasingly contributing to morbidity and mortality among women. The burden is not only related to the increasing incidence but also to the varied pathological features depending on the tissue of origin and pathogenesis. The study was carried out to find the prevalence and determine the clinical presentation and histo-pathological distribution of ovarian neoplasms. Management options were also noted.Methods: It is a retrospective study carried out at Goa Medical College between January 2013 to December 2015. All patients diagnosed and treated for ovarian neoplasm were included in the study. Data was tabulated using Microsoft Excel and descriptive statistical analysis was carried out using SPSS version 23.Results: A total of 3111 patients were admitted in gynecology at Goa Medical College during the specified time period. Of these 358 cases were diagnosed with ovarian neoplasm. On histopathology 196 were benign tumors and 162 were reported to be malignant. Commonest presenting symptom was abdominal distention seen in 51.1% of the patients, pain in 44.4%, followed by dyspepsia in 26.85%. Epithelial tumors were most common (Benign - 39.3%, Malignant - 41%) followed by sex cord stromal tumors and germ cell tumors in 7.26% of cases.Conclusions: Surface epithelial tumors were most common neoplasm. An alarming high no. of malignant tumors (45.25%) was found in present study. 44.4% tumors presented in 41-50 years age group. Presenting complaints were vague and nonspecific leading to delay in diagnosis. Histological type correlates with prognosis; therefore, preponderance of histological type will guide treatment options and patient education with respect to epidemiology.

Gross Examination

Intraoperative pathologic consultation plays an essential role in therapeutic decision making, possibly avoiding under or overtreatment of the patient. Common indications for intraoperative consultation include obtaining a diagnosis in an unknown pathology, ruling out malignancy, confirming a provisional diagnosis, and assessing margin status. Fifty patients undergoing surgery for soft tissue tumors or tumor-like lesions were included in the present prospective study to evaluate the role of intraoperative pathologic consultation by imprint and scrape cytology. Careful and quick gross examination of the specimen was performed, followed by processing for imprint and scrape smears. The prepared smears were evaluated by three pathologists and the cytological diagnosis compared subsequently with final histopathological diagnosis. Intraoperative consultation was primarily requested to make or confirm preoperative diagnosis. In 44.0% cases, no previous tissue/cytological diagnosis was available. In 56.0% cases, previous pathological diagnosis was available, but the reports were inconclusive or were reported from outside our institute. The diagnostic yield of imprint smears was 24% (5 malignant, 6 benign, and 1 inconclusive), and scrape smears was 100% (10 malignant, 38 benign, and 2 inconclusive). Paraffin-embedded sections yielded diagnosis in 100% cases (11 malignant, 38 benign, and 1 nonneoplastic). Imprint smears alone were not of much help in intraoperative diagnosis. Scrape smears were found to be superior to imprint smears in terms of diagnostic yield and accuracy. Combined imprint and scrape smear cytology did not provide any advantage in intraoperative provisional tissue diagnosis in soft tissue tumors.

Abstract The goal of glioma surgery is maximal safe resection in order to provide optimal tumor control and survival benefit to the patient. There are multiple imaging modalities beyond traditional contrast-enhanced magnetic resonance imaging (MRI) that have been incorporated into the preoperative workup of patients presenting with gliomas. The aim of these imaging modalities is to identify cortical and subcortical areas of eloquence, and their relationship to the lesion. In this article, multiple modalities are described with an emphasis on the underlying technology, clinical utilization, advantages, and disadvantages of each. functional MRI and its role in identifying hemispheric dominance and areas of language and motor are discussed. The nuances of magnetoencephalography and transcranial magnetic stimulation in localization of eloquent cortex are examined, as well as the role of diffusion tensor imaging in defining normal white matter tracts in glioma surgery. Lastly, we highlight the role of stimulated Raman spectroscopy in intraoperative histopathological diagnosis of tissue to guide tumor resection. Tumors may shift the normal arrangement of functional anatomy in the brain; thus, utilization of multiple modalities may be helpful in operative planning and patient counseling for successful surgery.

The primary aim of the study was to evaluate the role of [18F]Fluciclovine PET/CT in the characterization of intra-prostatic lesions in high-risk primary PCa patients eligible for radical prostatectomy, in comparison with conventional [11C]Choline PET/CT and validated by prostatectomy pathologic examination. Secondary aims were to determine the performance of PET semi-quantitative parameters (SUVmax; target-to-background ratios [TBRs], using abdominal aorta, bone marrow and liver as backgrounds) for malignant lesion detection (and best cut-off values) and to search predictive factors of malignancy. A six sextants prostate template was created and used by PET readers and pathologists for data comparison and validation. PET visual and semi-quantitative analyses were performed: for instance, patient-based, blinded to histopathology; subsequently lesion-based, un-blinded, according to the pathology reference template. Among 19 patients included (mean age 63 years, 89% high and 11% very-high-risk, mean PSA 9.15 ng/mL), 45 malignant and 31 benign lesions were found and 19 healthy areas were selected (n = 95). For both tracers, the location of the “blinded” prostate SUVmax matched with the lobe of the lesion with the highest pGS in 17/19 cases (89%). There was direct correlation between [18F]Fluciclovine uptake values and pISUP. Overall, lesion-based (n = 95), the performance of PET semiquantitative parameters, with either [18F]Fluciclovine or [11C]Choline, in detecting either malignant/ISUP2-5/ISUP4-5 PCa lesions, was moderate and similar (AUCs ≥ 0.70) but still inadequate (AUCs ≤ 0.81) as a standalone staging procedure. A [18F]Fluciclovine TBR-L3 ≥ 1.5 would depict a clinical significant lesion with a sensitivity and specificity of 85% and 68% respectively; whereas a SUVmax cut-off value of 4 would be able to identify a ISUP 4-5 lesion in all cases (sensitivity 100%), although with low specificity (52%). TBRs (especially with threshold significantly higher than aorta and slightly higher than bone marrow), may be complementary to implement malignancy targeting.

AbstractYolk sac tumors (YSTs) are a major histological subtype of malignant ovarian germ cell tumors with a relatively poor prognosis. The molecular basis of this disease has not been thoroughly characterized at the genomic level. Here we perform whole-exome and RNA sequencing on 41 clinical tumor samples from 30 YST patients, with distinct responses to cisplatin-based chemotherapy. We show that microsatellite instability status and mutational signatures are informative of chemoresistance. We identify somatic driver candidates, including significantly mutated genes KRAS and KIT and copy-number alteration drivers, including deleted ARID1A and PARK2, and amplified ZNF217, CDKN1B, and KRAS. YSTs have very infrequent TP53 mutations, whereas the tumors from patients with abnormal gonadal development contain both KRAS and TP53 mutations. We further reveal a role of OVOL2 overexpression in YST resistance to cisplatin. This study lays a critical foundation for understanding key molecular aberrations in YSTs and developing related therapeutic strategies.
