Insights into ovarian cancer: chemo-diversity, dose depended toxicities and survival responses. Med Oncol 2023; 40:111. [PMID: 36871128 DOI: 10.1007/s12032-023-01976-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 02/09/2023] [Indexed: 03/06/2023]
Abstract
Ovarian cancer has been one of the serious concerns for female health and medicinal practitioner all over the world. The wellness of over cancer patient is associated with survival responses which depends on many factors including chemotherapeutic diversity; treatment protocol; dose-dependent toxicity such as hematological toxicity and non-hematological toxicity. We found that the studied treatment regimens (TRs) (1-9) showed varying degree of hematological toxicities like moderate neutropenia (< 20%) critical neutropenia (> 20%), negligible leucopenia, critical leucopenia (> 20%), moderate thrombocytopenia (< 20%), critical thrombocytopenia (> 20%), moderate anemia (< 20%) and critical anemia (> 20%). The studied TRs showed varying degree of non-hematological toxicities like moderate nausea-vomiting (< 20%), critical nausea-vomiting (> 20%), moderate alopecia (< 20%), critical alopecia (> 20%), moderate fatigue (< 20%), critical fatigue (> 20%), moderate neurotoxicity (< 20%), critical neurotoxicity (> 20%), moderate diarrheas (< 20%). The studied TRs showed varying degree of survival responses like critical partial response (> 35%), remarkable overall responses (> 60%), critical overall responses (< 60%), remarkable stable disease (> 20%), critical stable disease (< 20%) and moderate progressive disease (< 20%). Out of the studied TRs 1-9, in case of TR 6, moderate non-hematological toxicity (NHT) and effective survival response (SR) is being diluted by critical hematological toxicity (HT). On the other hand, TR 8, 9 is showing critical HT, NHT and SR. Our analysis revealed that the toxicity of the existing therapeutic agents can be controlled through judicious decision of drug administration cycles and combination therapies.

Abstract
Ascites is defined as the accumulation of fluid in the peritoneal cavity, following an imbalance between production and reabsorption; it is detectable from 50 mL on ultrasound. Three mechanisms have been classically implicated, according to Starling's forces: an increase in the hydrostatic pressure gradient (increased portal venous pressure), a reduction in the oncotic pressure gradient (loss of total proteins, especially albumin), and an increase in peritoneal capillary permeability. This latter mechanism, plus the difference between lymph production and excretion (which favors the accumulation of exudate), explains some of the most notable causes of non-hypertensive ascites (according to the serum albumin in ascites gradient (SAAG)), including peritoneal carcinomatosis and tuberculosis. We present the case of a young man, originally from a tuberculosis endemic area, in whom the study of ascitic fluid guided the workup and the definitive diagnosis, which was unexpected for his age. Finally, a practical approach to non-hypertensive ascites is provided.

Endoscopic ultrasound guided fine needle biopsy (EUS-FNB) from peritoneal lesions: a prospective cohort pilot study. BMC Gastroenterol 2021; 21:400. [PMID: 34689752 PMCID: PMC8542287 DOI: 10.1186/s12876-021-01953-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Accepted: 09/29/2021] [Indexed: 11/10/2022] Open
Abstract
Background Diagnostic laparoscopy is often a necessary, albeit invasive, procedure to help resolve undiagnosed peritoneal diseases. Previous retrospective studies reported that EUS-FNA is feasible on peritoneal and omental lesions, however, EUS-FNA provided a limited amount of tissue for immunohistochemistry stain (IHC). Aim This pilot study aims to prospectively determine the effectiveness of EUS-FNB regarding adequacy of tissue for IHC staining, diagnostic rate and the avoidance rate of diagnostic laparoscopy or percutaneous biopsy in patients with these lesions. Methods From March 2017 to June 2018, patients with peritoneal or omental lesions identified by CT or MRI at the King Chulalongkorn Memorial Hospital, Bangkok, Thailand were prospectively enrolled in the study. All Patients underwent EUS-FNB. For those with negative pathological results of EUS-FNB, percutaneous biopsy or diagnostic laparoscopy was planned. Analysis uses percentages only due to small sample sizes. Results A total of 30 EUS-FNB passes were completed, with a median of 3 passes (range 2–3 passes) per case. For EUS-FNB, the sensitivity, specificity, PPV, NPV and accuracy of EUS-FNB from peritoneal lesions were 63.6%, 100%, 100%, 20% and 66.7% respectively. Adequate tissue for IHC stain was found in 25/30 passes (80%). The tissues from EUS results were found malignant in 7/12 patients (58.3%). IHC could be done in 10/12 patients (83.3%). Among the five patients with negative EUS results, two underwent either liver biopsy of mass or abdominal paracentesis, showing gallbladder cancer and adenocarcinoma. Two patients refused laparoscopy due to advanced pancreatic cancer and worsening ovarian cancer. The fifth patient had post-surgical inflammation only with spontaneous resolution. The avoidance rate of laparoscopic diagnosis was 58.3%. No major adverse event was observed. Conclusions EUS-FNB from peritoneal lesions provided sufficient core tissue for diagnosis and IHC. Diagnostic laparoscopy can often be avoided in patients with peritoneal lesions. Supplementary Information The online version contains supplementary material available at 10.1186/s12876-021-01953-9.

Indwelling Peritoneal Catheter for Ascites Management in a UK District General Hospital: A Cohort Study. Healthcare (Basel) 2021; 9:healthcare9101254. [PMID: 34682934 PMCID: PMC8536105 DOI: 10.3390/healthcare9101254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 09/16/2021] [Accepted: 09/17/2021] [Indexed: 11/17/2022] Open
Abstract
Background: There is no national or local guidance for management of malignancy-related ascites (MRA). Modalities can include large volume paracentesis (LVP) and indwelling peritoneal catheter (IPeC) insertion. Objectives: We set up a local IPeC service and performed a retrospective review with local ethical (Caldicott) approval. We hypothesized that an IPeC service would reduce inpatient stay related to MRA management, would be acceptable to patients, and have minimal complications. Methods: Notes of all patients requiring IPeC insertion were reviewed. Descriptive statistical methodology was applied with continuous data presented as mean (standard deviation (SD); range) and categorical variables as frequencies or percentages. Integrated Palliative Care Outcome Scale (IPOS) scores were collected for IPeC patients. Results: Thirty-four patients were identified. They were predominantly female, with a mean age of 66.6 years and a wide range of cancer diagnoses. Twenty-nine were inserted as day case procedures, and 31 had preceding paracenteses (mean 2). Main complications were leakage (6(17%)), peritonitis (2(5.8%)), and skin infection (1(3%)). IPOS scores showed consistent improvement in symptoms. Conclusions: An IPeC service for malignant-related ascites is acceptable to patients and is associated with manageable complication rates. We present the development of our service and hope for widespread application.

Abstract
One of the common indications of ascitic fluid examination in gynecological oncopathology is the detection and classification of malignant cells, especially in cases of clinically suspicious tubo-ovarian masses. The present study was undertaken to assess and validate the diagnostic utility of cell blocks (CBs) and compare its results with the corresponding conventional smears, prepared from effusion samples. CBs were prepared by thromboplastin technique in 220 cases. In 208 cases, diagnostic concordance between results obtained from smears and corresponding CBs was evaluated. Various antibody markers were tested, as per individual case. The average age of patients was 52.2 years. Positive immunohistochemical (IHC) staining for various markers was observed in 182 cases (82.7%) The most frequently positive antibody marker was PAX8 (101/134), followed by p53 (85/92) [mutation type (either diffusely positive or completely negative)], WT1 (tumor cells) (80/112), calretinin (2/87) (diffuse), BerEP4 (21/49), CA125 (21/24), CK7 (31/39) and CK20 and CDX2, together (5/16). Various other IHC markers utilized, including their positive expression, were TTF1 (1/10), p40 (3/3), p63 (2/4), ER (21/29), HBME1 (1/7), GATA3 (1/4), and MIC2 (1/1). Complete diagnostic concordance between CBs and smears was observed in 170/208 cases (81.7%). There were 20 major discordances, 10 minor and 8 cases with sampling errors. IHC was useful in classifying 158/182 (86.8%) cases, including serous or Müllerian adenocarcinoma (n = 123), mostly high-grade (121); metastatic squamous carcinoma (3); gastrointestinal-type adenocarcinoma (8); pulmonary adenocarcinoma (1); breast adenocarcinoma (1); Ewing sarcoma (1); and mesothelioma (2). CBs are complementary to smears in the detection of gynecological malignancies, mostly high-grade serous adenocarcinomas. These provide an opportunity for testing several IHC markers, for a precise diagnosis, including in various uncommon case scenarios, associated with significant therapeutic implications.

Clinicopathological Study of 117 Body Fluids: Comparison of Conventional Smear and Cell Block Technique. CURRENT HEALTH SCIENCES JOURNAL 2020; 46:336-343. [PMID: 33717507 PMCID: PMC7948013 DOI: 10.12865/chsj.46.04.03] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 11/22/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND Cell block method (CB) has emerged as an invaluable tool for diagnosis of effusions. It can help overcome the problems faced by conventional smear (CS) by differentiating between reactive, inflammatory and malignant cells. The aim of the study is to compare and correlate the CB diagnosis with the CS findings of various pathological conditions including malignancy. MATERIALS AND METHODS Two years prospective cross-sectional study of 117 fluids received for routine examination and/or for cytology was conducted. CS as well as CB was simultaneously prepared from the fluid and the results were correlated and tabulated for statistical analysis. RESULTS Mean age of presentation was 43±21.1 years and male: female ratio was 1.3:1. Ascitic fluid (46.2%) was the most common followed by pleural (40.2%). Among malignancies, primary ovarian and lung carcinoma were the most common to present with malignant ascites (33.3%) and pleural effusion (66.7%) respectively. Six suspicious for malignancy on CS were provided a definitive diagnosis of malignancy on CB. Overall, CB increased the yield of malignancy by 8.3%. The agreement between CB and CS for malignant effusions and suspicious for malignancy were 41.7% and 14.3% respectively. Sensitivity of CS method when compared to CB, for malignant peritoneal and pleural effusions was 90% and 75% respectively while the specificity was 68% and 79% respectively. CONCLUSION CB has a better diagnostic yield of malignancy and helps in providing a definitive diagnosis for cases that are suspicious for malignancy on CS. Hence, CB should be routinely employed along with CS for all effusions.

Abstract
OBJECTIVES Ovarian borderline tumors (OBT) represent a heterogeneous group of lesions with specific management for each histological subtype. Thus, the correct histological diagnosis is mandatory. MATERIAL AND METHODS References were searched by PubMed from January 2000 to January 2018 and original articles in French and English literature were selected. RESULTS AND CONCLUSIONS OBT should be classified according to the last WHO classification. Any micro-invasion (foci<5mm) or microcarcinoma (foci<5mm with nuclear atypia and desmoplastic stromal reaction) should be indicated in the pathology report. In case of serous OBT, variants (classical or the micropapillary/cribriform) should be indicated (grade C). The peritoneal implants associated with OBT, should be classified as invasive or noninvasive, according to the extension into the underlying adipous tissue. If no adipous tissue is seen the term undetermined should be used (grade B). In case of mucinous OBT bilateral and/or with peritoneal implants or peritoneal pseudomyxoma a search for primitive gastrointestinal, appendiceal or biliopancreatic tumor should be performed (grade C). In case of OBT, a thorough sampling of the tumor is recommended, with 1 block/cm and 2 blocks/cm in case of mucinous OBT, serous OBT micropapillary variant, OBT with intraepithelial carcinoma or/and micro-invasion. Peritoneal implants should be examined in toto. Omentum without macroscopic lesion should be sampled in 4 to 6 blocks (grade C). In case of ovarian cyst suspicious for OBT, fine needle aspiration is not recommended (grade C). In case of ovarian tumor suspicious for OBT, intraoperative examination should be performed by a gynecological pathologist (grade C).

Diffusion-Weighted Magnetic Resonance Imaging as a Noninvasive Parameter for Differentiating Benign and Malignant Intraperitoneal Collections. ACTA ACUST UNITED AC 2020; 56:medicina56050217. [PMID: 32369983 PMCID: PMC7279298 DOI: 10.3390/medicina56050217] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 04/26/2020] [Accepted: 04/29/2020] [Indexed: 12/15/2022]
Abstract
Background and Objective: The imaging differentiation of benign from malignant intraperitoneal collections (IPCs) relies on the tumoral morphological modifications of the peritoneum, which are not always advocating for malignancy. We aimed to assess ascitic fluid with the apparent diffusion coefficient (ADC) to determine non-invasive, stand-alone, differentiation criteria for benign and malignant intraperitoneal effusions. Materials and Methods: Sixty-one patients with known IPCs who underwent magnetic resonance examinations for reasons such as tumor staging, undetermined abdominal mass and disease follow up were retrospectively included in this study. All subjects had a final diagnosis of the fluid based on pathological examinations, which were divided into benign (n = 37) and malignant (n = 24) IPCs groups. ADC values were measured separately by two radiologists, and the average values were used for comparing the two groups by consuming the independent samples t-test. The receiver operating characteristic analysis was performed to test the ADC values' diagnostic ability to distinguish malignant from benign collections. Results: The differentiation between benign and malignant IPCs based on ADC values was statistically significant (p = 0.0034). The mean ADC values were higher for the benign (3.543 × 10-3 mm2/s) than for the malignant group (3.057 × 10-3 mm2/s). The optimum ADC cutoff point for the diagnosis of malignant ascites was <3.241 × 10-3 mm2/s, with a sensitivity of 77.78% and a specificity of 80%. Conclusions: ADC represents a noninvasive and reproducible imaging parameter that may help to assess intraperitoneal collections. Although successful in distinguishing malignant from benign IPCs, further research must be conducted in order to certify if the difference in ADC values is a consequence of the physical characteristics of the ascitic fluids or their appurtenance to a certain histopathological group.

Abstract
Background: Micronucleus (MN) is an extranuclear body within the cell formed due to failure of incorporation of whole chromosomes or their fragments during cell division. MN scoring can be done to identify malignant effusions. Aims: This study aimed to score micronuclei to distinguish malignant effusion from benign effusions and to correlate MN score with type of malignant effusion. Methods and Materials: A retrospective study was conducted on 30 malignant and 30 benign effusions. The number of micronucleated cells per 1,000 cells was counted in effusion smears stained with Papanicolaou stain under oil immersion (1,000×). Results: The mean MN score in malignant effusions was 3.77 with standard deviation (SD) of 2.13. The mean MN score in benign effusions was 0.50 with SD of 0.57. The difference in MN score between malignant and benign effusions is statistically significant (P < 0.001). A cut-off MN score of 6.5 was seen to distinguish malignant and benign effusions with 100% specificity and 100% sensitivity in this study. Conclusions: MN score is higher in malignant effusions when compared with benign effusions. This can be used to differentiate malignant effusions from benign effusions in low resource setting.

Abstract
Background Abdominal paracentesis is a routine diagnostic procedure for assessment of patients with recent onset or worsening of ascites. Objectives The objective of the study is to (1) review clinically confirmed cases of malignancy with negative, atypical, and suspicious cytology reports and provide reasoning for discrepancies and (2) recalculate sensitivity, specificity, and predictive values after review. Materials and Methods Papanicolaou smears of ascitic fluid paracentesis samples received over one calendar year were reviewed retrospectively by an expert in cytopathology blinded to the final clinical and/or histopathological diagnoses. Cases with discrepancies after review were noted. Sensitivity, specificity, and predictive values were calculated before and after review of slides. Data were analyzed using SPSS version 16. Results Malignant etiology was identified in 49/115 cases (42.6%) with female genital tract being the most common site of malignancy (22, 44.8%). The remaining 66 (57.4%) had a benign etiology with hepatic cirrhosis in 42 cases (63.6%). A review revealed discrepancies in five cases, three of which were earlier called negative for malignant cells (one case each of ovarian adenocarcinoma, cecal adenocarcinoma, and cholangiocarcinoma). Two cases of ovarian adenocarcinoma that were reported as atypical/reactive mesothelial hyperplasia showed malignant cells upon review. Sensitivity and specificity after review were 69.4% and 100%, respectively, with 100% positive predictive value. Conclusion Being a minimally invasive procedure, abdominal paracentesis continues to be an important diagnostic tool in guiding patient management. A proper morphological assessment with adequate clinical information and correlation with other investigations can be used to arrive at a definitive diagnosis in most cases. The term "atypical" can be misleading and is often used for want of clinical information and is best avoided.

Abstract
RATIONALE Lymphoma with an initial manifestation of ascites and peritoneal invasion is rare. PATIENT CONCERNS A 65-year-old woman presented to the emergency department with a 3-week history of abdominal distention, anorexia, and night sweating, and a 2-week history of melena. She was a silent hepatitis B virus carrier. Abdominal ultrasound showed massive ascites without cirrhosis. Abdominal computed tomography revealed ascites, infiltrative peritoneal lesions with omental cake appearance, and lymphadenopathies. DIAGNOSIS We performed paracentesis and the ascites cytology was obtained. The patient also underwent esophagogastroduodenoscopy, which showed ulcerative tumors in the stomach. Both ascites cytology and pathology of the gastric tumors confirmed the diagnosis of B-cell lymphoma. INTERVENTIONS This patient received 7 cycles of chemotherapy. OUTCOMES Follow-up imaging studies revealed partial remission of lymphoma, but an enlargement of residual tumors in omentum and mesentery, which resulted in intractable ascites and rapid deterioration of performance status. Despite a change of regimen of chemotherapy, this patient expired 10 months after diagnosis. LESSONS Lymphoma should be one of the differential diagnoses in patients with intractable ascites not attributable to other comorbidities.

Abstract
OBJECTIVES Ovarian carcinomas represent a heterogeneous group of lesions with specific therapeutic management for each histological subtype. Thus, the correct histological diagnosis is mandatory. MATERIAL AND METHODS References were searched by PubMed from January 2000 to January 2018 and original articles in French and English literature were selected. RESULTS AND CONCLUSIONS In case of ovarian mass suspicious for cancer, a frozen section analysis may be proposed, if it could impact the surgical management. A positive histological diagnosis of ovarian carcinoma (type and grade) has to be rendered on histological (and not cytological) material before any chemotherapy with multiples and large sized biopsies. In case of needle biopsy, at least three fragments with needles>16G are needed. Histological biopsies need to be formalin-fixed (4% formaldehyde) less than 1h after resection and at least 6hours fixation is mandatory for small size biopsies. Tissue transfer to pathological labs up to 48hours under vacuum and at +4°C (in case of large surgical specimens) may be an alternative. Gross examination should include the description of all specimens and their integrity, the site of the tumor and the dimension of all specimens and nodules. Multiples sampling is needed, including the capsule, the solid areas, at least 1 to 2 blocks per cm of tumor for mucinous lesions, the Fallopian tube in toto, at least 3 blocks on grossly normal omentum and one block on the largest omental nodule. WHO classification should be used to classify the carcinoma (type and grade), with the use of a panel of immunohistochemical markers. High-grade ovarian carcinomas (serous and endometrioid) should be tested for BRCA mutation and in case of a detectable tumor mutation, the patient should be referred to an oncogenetic consultation.

Targeted deep sequencing of effusion cytology samples is feasible, informs spatiotemporal tumor evolution, and has clinical and diagnostic utility. Genes Chromosomes Cancer 2017; 57:70-79.

Abstract
During the course of disease, many cancer patients eventually present with metastatic disease including peritoneal or pleural spread. In this context, cytology specimens derived from ascites or pleural effusion may help to differentiate malignant from benign conditions and sometimes yield diagnosis of a malignancy. However, even when supported by immunohistochemistry, cytological interpretation can be challenging, especially if tumor cellularity is low. Here, we investigated whether targeted deep sequencing of formalin-fixed and paraffin embedded (FFPE) cytology specimens of cancer patients is feasible, and has diagnostic and clinical impact. To this end, a cohort of 20 matched pairs was compiled, each comprising a cytology sample (FFPE cell block) and at least one biopsy/surgical resection specimen serving as benchmark. In addition, 5 non-malignant effusions were sequenced serving as negative-controls. All samples yielded sufficient libraries and were successfully subjected to targeted sequencing employing a semiconductor based next-generation sequencing platform. Using gene panels of different size and composition, including the Oncomine Comprehensive Assay, for targeted sequencing, somatic mutations were detected in the tissue of all 20 cases. Of these, 15 (75%) harbored mutations that were also detected in the corresponding cytology samples. In four of these cases (20%), additional private mutations were detected in either cytology or tissue samples, reflecting spatiotemporal tumor evolution. Of the five remaining cases, three (15%) showed wild type alleles in cytology material whereas tumor tissue had mutations in interrogated genes. Two cases were discordant, showing different private mutations in the cytology and in the tissue sample, respectively. In summary, sequencing of cytology specimens (FFPE cell block) reflecting spatiotemporal tumor evolution is feasible and yields adjunct genetic information that may be exploitable for diagnostics and therapy.

Abstract
OBJECTIVE The objective was to determine how often peritoneal cytology is positive for malignancy in women with known ovarian cancer. Knowing this fact would help determine the usefulness of diagnostic paracentesis. METHODS Records of all women diagnosed with invasive epithelial ovarian cancer from 2004 to 2012 were examined to correlate presence of ascites, cytologic, and pathologic findings. RESULTS A total of 313 patients were included in analysis. A total of 210 of 313 patients (67.1%) with ascites had cytology positive for malignancy. This left 103 patients with ascites and cancer without malignant cells found in the ascites removed at the time of surgery. CONCLUSIONS Except in a few cases, paracentesis is not recommended for the diagnosis of ovarian cancer because of the potential spreading of cancer. Furthermore, with only just over two thirds of cases of known cancer and ascites having cytology positive for malignancy, the value of paracentesis for diagnosis of ovarian cancer is minimal.

Abstract
PURPOSE To determine the efficacy and safety of percutaneous omental biopsy. METHODS Retrospective review was performed of all 181 percutaneous omental biopsies performed at a single institution between 9/18/2002 and 2/12/2016. Mean patient age was 67 (±14) years, and 114 (63%) patients were female. Biopsy results were compared to subsequent surgical pathology and paracentesis cytology, when available, and cases were further evaluated based on the imaging appearance of the omental abnormality. Complications were classified using Society of Interventional Radiology (SIR) consensus guidelines. RESULTS Of the 181 cases, histopathology was positive for malignancy in 166 (92%) patients and showed benign inflammation/fibrosis in 15 (8%) patients. Seventy-three (40%) patients underwent subsequent surgery, and omental malignancy was diagnosed in every case. Percutaneous omental biopsy and surgical pathology results were concordant in all but 1 case (diagnostic accuracy of 99%). In contrast, the accuracy of paracentesis cytology in surgically confirmed malignant cases was only 76% (p = 0.004). Biopsy was positive for malignancy in 95% of patients with omental caking, 92% with omental nodularity, 80% with a single omental nodule, and 20% with omental thickening (p = <0.001). In 118 (65%) patients, a previously unknown (new or additional) malignancy was diagnosed. No clinically significant complications occurred. CONCLUSIONS Percutaneous biopsy is an effective and safe method to evaluate omental abnormalities. Omental biopsy is more sensitive than paracentesis cytology for determining malignancy. Omental malignancy is more likely as the abnormality advances through the spectrum of imaging appearances from omental thickening to omental caking.

Diagnostic and prognostic value of SHOX2 and SEPT9 DNA methylation and cytology in benign, paramalignant, and malignant ascites. Clin Epigenetics 2016; 8:24. [PMID: 26937257 PMCID: PMC4774089 DOI: 10.1186/s13148-016-0192-7] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2015] [Accepted: 02/25/2016] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Cytology remains the gold standard for the detection of malignant cells in ascites. However, its sensitivity is limited. The aim of this study was to evaluate DNA methylation biomarkers for the differential diagnosis of benign (ascites in patients without malignancy), malignant (ascites in cancer patients directly caused by malignancy), and paramalignant (ascites in cancer patients caused by comorbidities but not by malignancy) ascites. METHODS A cohort of 283 patients (134 cancer patients, 149 patients with benign diseases) presenting with ascites was prospectively enrolled. Ascites was evaluated by means of cytopathological investigation and DNA methylation of SHOX2 and SEPT9 in the cell-free and cellular fraction. DNA methylation in bisulfite-converted DNA was determined using quantitative methylation specific real-time PCR. Cytopathological and DNA methylation results were evaluated with regard to diagnosis and overall survival (OS). RESULTS Patients with positive DNA methylation had a poor overall survival compared to methylation-negative patients (hazard ratio: HR = 1.97, p = 0.001). In multivariate survival analysis, DNA methylation was an independent prognostic parameter (p = 0.003) together with age (HR = 1.03, p < 0.001) and the presence of malignant disease (HR = 1.87, p < 0.001). The combination of methylation with cytopathological analyses led to a 42 % increase in the detection rate of malignant ascites, resulting in 37 % positively diagnosed cancer patients and a specificity of 97 %. Among cancer patients, patients with DNA methylation-positive ascites showed an adverse clinical course (HR = 1.63, p = 0.039). CONCLUSIONS DNA methylation testing adds diagnostic and prognostic information and might constitute an effective ancillary method for the differential diagnosis of malignant, paramalignant, and benign ascites.

A specimen volume of ≥80 mL improves cytologic sensitivity for malignant ascites: a retrospective analysis of 2665 cases. J Am Soc Cytopathol 2016; 5:301-305. [PMID: 31042507 DOI: 10.1016/j.jasc.2016.04.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2016] [Revised: 04/14/2016] [Accepted: 04/14/2016] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Although paracentesis simultaneously allows cytologic evaluation of peritoneal fluid and symptomatic relief, its utility is limited by a paltry 50% to 60% sensitivity for malignancy. Specimen volume has recently been shown to affect cytologic diagnosis in other body fluids, but its role has never been examined in ascites. This study evaluates how specimen volume impacts cytologic diagnosis of malignant ascites. MATERIALS AND METHODS We identified 2665 consecutive paracentesis specimens with documented numeric volumes collected at our institution between 1994 and 2013. We separated the cases into 10 bins of roughly equivalent sample size and compared the percentage of cases that received malignant diagnoses across each cutoff volume. When follow-up pathology was available, we also compared the sensitivity of cytology with the gold standard of surgical pathology. RESULTS The peritoneal fluids had a mean volume of 760.2 mL (range: 1-10,000). Just 11.3% of specimens with volumes <80 mL were diagnosed as malignant, while 20.1% were malignant at volumes ≥80 mL (P < 0.001, OR = 0.51, 95% CI = 0.39-0.64). Lower volume specimens also had more indeterminate and nondiagnostic results. Cytologic sensitivity increased from 56.7% for specimens <80 mL to 75.4% for volumes ≥80 mL (P = 0.03, OR = 0.43, 95% CI = 0.19-0.94). CONCLUSIONS A specimen volume of ≥80 mL is associated with increased cytologic sensitivity for malignant ascites and a higher rate of malignant diagnoses. The disparate sensitivity at lower volumes likely stems from inadequate sampling of larger specimens. Although fluids should not be summarily rejected based on volume, a specimen volume of ≥80 mL minimizes the influence of specimen size on diagnostic adequacy in paracentesis specimens.

Ascites in Ovarian Carcinoma - Reliability and Limitations of Cytological Analysis. W INDIAN MED J 2015; 64:236-40. [PMID: 26426176 DOI: 10.7727/wimj.2014.230] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2014] [Accepted: 12/11/2014] [Indexed: 02/06/2023]
Abstract
OBJECTIVE The objective of this study was to examine the validity of ascitic fluid cytology in the detection of pathological findings, to examine the percentage of false positive and false negative results in the cytology of ascitic fluid and to determine the validity of peritoneal cytology in relation to the histopathological type of the ovarian tumour. METHODS This retrospective study included 170 peritoneal cytology findings. The study was conducted from January 2010 to December 2012. The experimental group included 76 cytology findings obtained from patients diagnosed with ovarian carcinoma, whereas the control group was composed of 94 cytology findings of benign ovarian tumours and liver cirrhosis ascites. The patients with ovarian carcinoma had grades III, as well as grades I and IIc but only in cases where operative and pathological finding indicated a ruptured or perforated tumour capsule. RESULTS The sensitivity of peritoneal cytology is 68.92%, specificity is 93.61%, positive predictive value is 89.65% and negative predictive value is 78.57%. In 30.02% of patients, the peritoneal cytology showed false negative results, while in 6.38%, the results were false positive. The highest percentage of false negative findings was 77%, found in endometrioid carcinoma. CONCLUSION Peritoneal cytology of ascitic fluid is highly specific but has relatively low sensitivity, particularly in the case of endometrioid ovarian carcinoma. In order to increase sensitivity, peritoneal cytology should be combined with monoclonal antibodies and other biochemical and immunohistochemical markers.

Positive peritoneal cytology at interval surgery is a poor prognostic factor in patients with stage T3c advanced ovarian carcinoma: A retrospective study. J Obstet Gynaecol Res 2014; 41:755-62. [PMID: 25421004 DOI: 10.1111/jog.12616] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2014] [Accepted: 09/08/2014] [Indexed: 01/02/2023]
Abstract
AIM The purpose of our study is to investigate clinically significant prognostic factors at the time of interval surgery (IS), comprising interval look surgery and interval debulking surgery, for T3c (International Federation of Gynecology and Obstetrics stage IIIc to IV) advanced ovarian cancer (AOC) patients during primary treatment. METHODS We reviewed records of patients with T3c AOC who underwent IS following neoadjuvant chemotherapy or up-front primary debulking surgery with adjuvant chemotherapy at our institution between January 1996 and December 2010. For analysis of prognostic factors, cytology of peritoneal exfoliative cells at IS was added to clinicopathological variables. RESULTS A retrospective analysis was performed on 50 cases. The median age was 61.1 years (range, 38-78), with median follow-up of 45.9 months (range, 12-122). Macroscopic tumors were completely resected in 32 cases (64%) at IS. Univariate analyses of clinicopathological factors for IS identified preoperative serum cancer antigen-125 levels (≥20 IU/mL; P = 0.0539), number of residual lesions at IS (≥20; P = 0.0554), incomplete surgery at IS (P = 0.0171) and positive peritoneal cytology at IS (P = 0.0015) as significant factors for prognosis regarding progression-free survival (PFS). Multivariate analysis identified positive peritoneal cytology (P = 0.0303) as a unique independent predictor of poor prognosis in PFS. CONCLUSION Positive peritoneal cytology at IS appears to be a significant factor for poor prognosis in PFS, which may provide useful information for post-IS chemotherapy planning. IS in the treatment of AOC may be useful for not only complete resection, but also for identification of patients with poor prognosis.

Abstract
PURPOSE Image-guided needle biopsy represents a minimally invasive method for pathologic diagnosis of a mass. This study evaluates the diagnostic yield, accuracy, and safety of ovarian mass biopsy with combined core and fine-needle technique. MATERIALS AND METHODS Medical records of all women at least 18 years of age, referred from gynecologic oncology, who underwent image-guided ovarian mass biopsy from 2001 through 2011 were reviewed. Among 27 patients, ultrasound guidance was used in 13 (48%), six transabdominal and seven transvaginal; computed tomography guidance was used in 14 (52%), nine transabdominal and five transgluteal. Biopsy indications were suspected metastasis (n = 15; 56%), suspected ovarian cancer to be treated with neoadjuvant chemotherapy (n = 10; 37%), and relative contraindication to surgery (n = 2; 7%). Mean maximum lesion dimension was 9.9 cm (range, 2-23 cm), with solid composition in nine (33%), cystic in six (22%), and mixed in 12 (44%). Biopsy pathologic findings were compared versus those of the surgical specimen or, for masses that were not resected, versus the stability of benign masses and response to chemotherapy of malignant masses on follow-up. RESULTS All biopsies yielded a diagnosis. No biopsy-related complications were noted. Eleven patients (41%) did not undergo lesion resection and were followed for an average of 28.8 months (range, 0.3-118.4 mo). In no patient did malignancy develop during clinical follow-up after a benign biopsy diagnosis. Sensitivity and specificity for diagnosis of malignancy were 100% ± 0 (19 of 19) and 88% ± 26 (seven of eight), respectively, for cancer detection. In nine patients (33%) with final pathologic diagnosis of epithelial ovarian cancer, tumor seeding was not observed during a mean follow-up of 44.6 months (range, 1.3-110.2 mo). CONCLUSIONS Image-guided ovarian mass core needle biopsy results in a pathologic diagnosis of benign and malignant masses with high yield, accuracy, and safety.

Abstract
Analysis of ascitic fluid should help to identify and characterize malignant cells in gastrointestinal cancer. However, despite a high specificity, the sensitivity of traditional ascitic fluid cytology remains insufficient, at around 60%. Since 2004 the CellSearch
® technology has shown its advantages in the detection of circulating tumor cells (CTCs) in peripheral blood, which can perform an accurate diagnosis and molecular analysis at the same time. To our knowledge, no previous study has explored the potential utility of this technology for the detection and quantification of tumor cells in ascitic fluid samples. Herein we report a case of metastatic esophageal adenocarcinoma in a 70-year-old man presenting with dysphagia and a large amount of fluid in the peritoneal cavity. Analysis of a peripheral blood sample and ascites sample with the CellSearch
® technology both revealed the presence of putative tumor cells that were positive for epithelial cell adhesion molecule (EpCAM) and cytokeratin (CK) expression. This study confirmed the hematogenous dissemination of esophageal cancer by the detection of circulating tumor cells in the peripheral blood, and is the first to demonstrate that tumor cells can be identified in ascitic fluid by using CellSearch
® technology.

Abstract
Background Serum ascites albumin gradient (SAAG) has been recognized as a reliable marker in the differential diagnosis of ascites. The etiological background of cirrhosis is rather different between western countries and eastern countries. The threshold of SAAG in Chinese ascitic patients has not been evaluated yet. The aim of this study was to define a new reasonable threshold of SAAG in Chinese ascitic patients. Methods Adult patients with ascites admitted to the Shanghai Changzheng Hospital from Jan 2004 to Jun 2010 were retrospectively analyzed. The diagnostic criteria for cirrhotic ascites are clinical manifestations, radiological features and esophageal-gastric varicosis, or histopathology. Serum was detected by chemical method using a commercial kit. We used receiver operating characteristic (ROC) analysis to achieve maximal sensitivity and specificity of SAAG. Results The mean value of SAAG in portal-hypertension-related ascites was significantly higher than that in the non-portal-hypertension-related ascites (21.15 ± 4.38 g/L vs 7.48 ± 3.64 g/L, P = 0.002). The SAAG cut-off value under 12.50 g/L predicted portal hypertension ascites with the sensitivity of 99.20%, specificity of 95.10% and accuracy of 97.65%. Conclusions SAAG is useful to distinguish portal-hypertension-related ascites and non-portal-hypertension-related ascites, and 12.50 g/L might present as a more reasonable threshold in Chinese ascitic patients.

Abstract
Ascitic fluid samples are frequently sent to the laboratory for analysis. Although the underlying cause of the ascites is often thought to be clinically obvious, it is important to establish a definitive diagnosis. The value of a cell count and bacterial culture of the ascitic fluid is not disputed, but the role of biochemical testing is less clear. The use of ascitic fluid total protein to try to classify ascitic fluids as either an exudate or a transudate has contributed to this. The use of the physiologically based serum ascites albumin gradient to differentiate ascites caused by portal hypertension from other causes provides a better diagnostic approach. We recommend that the serum ascites albumin gradient is performed by laboratories as the first-line test and that interpretative reports are provided. Additional testing should be restricted to specific diagnostic queries and requires close collaboration between the laboratory and the clinician.

EUS-guided FNA of peritoneal carcinomatosis in patients with unknown primary malignancy. Gastrointest Endosc 2009; 70:1266-70. [PMID: 19640520 DOI: 10.1016/j.gie.2009.05.031] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2009] [Accepted: 05/25/2009] [Indexed: 02/08/2023]
Abstract
BACKGROUND EUS-guided FNA is a well-recognized technique for sampling the pancreas, peri-intestinal lymph nodes, and mass lesions. The role of EUS-guided FNA in the diagnosis of peritoneal carcinomatosis has not been well studied. OBJECTIVE We aimed to determine the feasibility and success in sampling lesions in the peritoneum suspicious for carcinomatosis without a primary source. DESIGN An observational study. SETTING A tertiary referral center. PATIENTS Consecutive patients who underwent EUS-guided FNA of peritoneal deposits. RESULTS During a span of 3 years, 4 patients underwent transgastric or transduodenal EUS-guided FNA of peritoneal lesions with a curvilinear echoendoscope. All of these lesions were imaged by abdominal CT scan. The EUS findings of the nodules appeared round, relatively hypoechoic to the surrounding tissue, but hyperechoic when compared with the surrounding low-volume ascites where the lesions floated. Four passes were performed per case, and the diagnosis was achieved on a median of 2 passes (range 1-4). All patients received intravenous antibiotics during the procedure. Two patients had metastatic adenocarcinoma, 1 patient had lymphoma, and 1 patient had metastatic breast carcinoma. Diagnostic laparoscopy/laparotomy was avoided in all patients. No complications, particularly peritonitis, were encountered. LIMITATIONS Observational study with a small sample size. CONCLUSIONS Transgastric or transduodenal EUS-guided FNA for peritoneal carcinomatosis is feasible and safe. In the setting of an unknown primary cancer, EUS-guided FNA facilitates acquisition of tissues for treatment allocation, thus avoiding the need for laparoscopy or laparotomy.

Abstract
PURPOSE We report the case of puerperal ascites, associated with elevated CA125 levels and secondary to a uterine myoma. The literature on pseudo-Meigs' syndrome associated with pregnancy was reviewed. CASE A 35-year-old woman complained of abdominal distension 2 days after a spontaneous vaginal delivery. A mass of 5 cm in the right uterine corner had been detected during the first trimester ultrasound and had been diagnosed as subserosal myoma. Physical examination and ultrasound revealed massive ascites. Computed tomography confirmed ascites and laboratory investigations showed CA125 raised levels. Cytology of ascitic fluid resulted negative for malignancy. A laparotomy was performed and a large pedunculated myoma was removed. A final diagnosis of atypical pseudo-Meigs' syndrome was performed, being computed tomography and chest X-ray negative for pleural effusion. CONCLUSIONS To the best of our knowledge, this is the first case of pseudo-Meigs' syndrome caused by a uterine leiomyoma described in puerperium and without hydrothorax. Though ascites is very rare in obstetrics, it should be considered when evaluating puerperal patients complaining of abdominal distension.

Abstract
In patients with suspected advanced ovarian carcinoma, a precise histological diagnosis is required before commencing neo-adjuvant chemotherapy. This study aims to determine the diagnostic accuracy and complication rate of percutaneous biopsies performed under ultrasound or computed tomography guidance. Between 2002 to 2007, 60 consecutive image-guided percutaneous biopsies were performed in patients with suspected ovarian cancer. The following variables were recorded: tissue biopsied, imaging technique, experience of operator, biopsy needle gauge, number of passes, complications, and final histology. Forty-seven patients had omental biopsies, 12 pelvic mass biopsies, and 1 para-aortic lymph node biopsy. Thirty-five biopsies were performed under ultrasound, 25 under computed tomography guidance. Biopsy needle gauges ranged from 14-20 swg with two to five passes for each patient. There were no complications. Histology was obtained in 52 (87%) patients. Percutaneous image-guided biopsy of peritoneal disease or pelvic mass is safe with high diagnostic accuracy. The large-gauge biopsy needle is as safe as the small gauge needle, but has the added value of obtaining tissue samples for immunohistochemistry and genomic studies.

Abstract
Struma ovarii is a rare ovarian teratoma consisted predominantly of mature thyroid tissue. Although the vast majority of strumas are benign, they can present mimicking malignancy. We report a case of a postmenopausal woman who presented with a large pelvic mass, ascites, and high CA125 levels. Further investigation confirmed the existence of bilateral pleural effusions. The patient underwent laparotomy, and histology revealed a benign struma ovarii. Twelve months after the removal of the tumor, the patient remained disease free, with no clinical or radiologic evidence of effusion, and normal CA125 levels. This is only the fifth case in the English literature of a benign struma ovarii presenting as pseudo-Meigs' syndrome with elevated CA125. Struma ovarii should be included in the differential diagnosis of a pelvic mass that presents with ascites, hydrothorax, and elevated tumor markers.
