Metabolic Markers

ObjectiveMetabolic pathway alterations in cancer are thought to be dependent upon tumor type–specific oncogenic activation and local nutrient and oxygen supply during disease progression. In serous ovarian cancer, the typical peritoneal spread of disease is caused by shedding of tumor cells into the abdominal cavity, often along with ascites formation. Not much is known about the metabolic features of these detached serous tumor cells. In this study, we investigate the messenger RNA (mRNA) expression of GAPDH (glycolytic glyceraldehyde 3-phosphate dehydrogenase) and PKM2 (pyruvate kinase isoform M2), ATP5B (mitochondrial β-F1-ATPase), and heat shock protein 60 in matched serous solid tumor and corresponding ascites.Materials/MethodsFresh samples from solid tumor and corresponding ascites were prospectively collected from 40 patients undergoing primary surgery for suspected advanced ovarian cancer. Of these, 25 met the study eligibility criteria, that is, stage IIC to IV disease of the serous (24) or endometrioid (1) subtype with solid and ascites specimens containing 50% or more tumor cells and with good quality and quantity mRNA yield. All but 2 patients (92%) had type II disease. GAPDH, PKM2, ATP5B, and HSP60 mRNA expressions were assessed by real-time polymerase chain reaction. For each marker, the mRNA expression in solid tumor was pairwise compared with the corresponding expression in ascites using the Wilcoxon matched pairs signed rank sum test.ResultsIn contrast to our hypothesis, the mRNA expression of analyzed metabolic markers and HSP60 did not significantly differ between matched solid tumor and malignant ascites.ConclusionsOur results indicate that further expression changes in genes related to glycolysis or oxidative phosphorylation are not a prerequisite for serous cancer cell survival after detachment.

AbstractSplenosis is a rare disease, which is often discovered incidentally years after surgical procedures on the spleen or traumatic splenic lesions. Through injury of the splenic capsule, splenic cells are able to spread and autoimplant in a fashion similar to the process of metastatic cancer. Here we present the case of a 62-year-old female patient with a palpable tumor of the lower abdomen. Her medical history was unremarkable, except for splenectomy after traumatic splenic lesion in her childhood. Clinical examination and diagnostic imaging raised the suspicion of advanced ovarian cancer, which was further substantiated by the typical presentation of adnexal masses and disseminated peritoneal metastases during the following staging laparotomy. Surprisingly, we also found peritoneal implants macroscopically similar to splenic tissue. Microscopic examination of tissue specimens by intrasurgical frozen section confirmed the diagnosis of intra-abdominal splenosis. The patient then underwent cytoreductive surgery with complete resection of all cancer manifestations, sparing the remaining foci of splenosis to avoid further morbidity. This case demonstrates the rare coincidence of intra-abdominal carcinoma and splenosis, which could lead to intraoperative difficulties by misinterpreting benign splenic tissue. Therefore, splenosis should be considered in patients with medical history of splenic lesions and further diagnostic imaging like Tc-99m-tagged heat-damaged RBC scan could be used for presurgical distinguishing between tumor spread in the abdominal cavity and disseminated splenosis. The presented case report should not only raise awareness for the rare disease splenosis, but also emphasize the need to consider the possibility of simultaneous incidence of benign and malignant intra-abdominal lesions, as to our knowledge this is the first published case of simultaneous peritoneal carcinomatosis and splenosis.

Ovarian cancer (OC) is able to develop implantation metastases in the abdominal cavity. Ascites is potentially useful for evaluating cancer features. The aim of the study was to assess the content of stem-like tumor cells and inflammatory mediators in ascites of OC. The prospective study included 11 patients with primary OC having ascites, 8 patients with benign ovarian tumors having ascites and 22 healthy women. In ascitic fluid obtained by laparocentesis, the populations of tumor stem-like cells were determined on a Cytoflex S` flow cytometer (Beckman Coulter, USA) and CytExpert Software using monoclonal antibodies to CD45, CD44 and CD133. The cytokine profiles of ascitic fluid and blood serum (IL-1β, IL-18, IL-4, IL-10 and VEGF) were assessed by ELISA. Stem-like cells were found in all samples. 5 cell populations were evaluated. The number of cells expressing both markers: CD44 + and CD133+, was the lowest. The highest, about 32%, was the number of CD44+ cells. The number of cells CD45-CD44+CD133- in ascites strongly positively correlated with the content of IL-10 in ascites, and the numbers of CD45-CD133+ and CD45-CD44-CD133+ - with the level of VEGF in blood serum. No correlations were found between the numbers of stem-like cells and the disease stage or the level of CA125 in blood. The combination of IL-4 and IL-10 in ascites had the greatest significance in predicting the disease stage. These results suggest a relationship between the levels of VEGF, IL-10, and cancer stem cells in the OC ascites. Stem-like cells in OC ascites are heterogeneous and are present even at an early stage of the disease. It seems promising to study cell populations and cytokine profile of ascites together, to assess the biomarker potential of their combination.

Ovarian cancer is the seventh most common gynaecologic malignancy seen in women. Majority of the patients with ovarian cancer are diagnosed at the advanced stage making prognosis poor. The standard management of advanced ovarian cancer includes tumour debulking surgery followed by chemotherapy. Various types of chemotherapeutic regimens have been used to treat advanced ovarian cancer, but the most promising and the currently used standard first-line treatment is carboplatin and paclitaxel. Despite improved clinical response and survival to this combination of chemotherapy, numerous patients either undergo relapse or succumb to the disease as a result of chemotherapy resistance. To understand this phenomenon at a cellular level, various macromolecules such as DNA, messenger RNA and proteins have been developed as biomarkers for chemotherapy response. This review comprehensively summarizes the problem that pertains to chemotherapy resistance in advanced ovarian cancer and provides a good overview of the various biomarkers that have been developed in this field.

American Cancer Society identifying ovarian carcinoma as the gynecologic malignancy with the highest case-to-fatality. Ovarian carcinoma metastasizes either by direct extension from the ovarian/fallopian tumor to neighboring organs (bladder/colon) or when cancer cells detach from the primary tumor. Exfoliated tumor cells are transported throughout the peritoneum by physiological peritoneal fluid and disseminate within the abdominal cavity. Extensive seeding of the peritoneal cavity by tumor cells is often associated with ascites, particularly in advanced, high-grade serous carcinomas. CD70 (encoded by the TNFSF7 gene) is a co-stimulatory factor present on B-cells, activated T-cells, and dendritic cells. CD70 is over expressed in tumor cells of various solid cancers including ovarian carcinoma, recently reported the role of CD70 expression as a predictive marker of resistance to chemotherapy in ovarian cancers. We evaluated the expression of CD70 level in the pathogenesis of metastasis ovarian cancer cell. Seventy five tissue samples from metastatic ovarian carcinoma were evaluated by quantitative real-time PCR for CD70 and statistical analyses were performed using the Mann-Whitney test. Further, humanized anti-CD70 antibodies were investigated in xenograft mice models of ovarian cancer. Increasing expression of CD70 level was associated with increased risks for disease progression (HR = 1.04; 95% CI, 1.03 to 1.14) and death (HR = 1.13; 95% CI, 1.09 to 1.2). expression of CD70 was associated with a worse PFS and OS compared with non- expression of CD70 carcinomas. Furthermore, humanized anti-CD70 antibodies have shown significant antitumor activity in preclinical xenograft models of ovarian cancer cell.

ObjectiveThe aim of this study was to assess the use of the pathological response to neoadjuvant chemotherapy (NAC) for predicting disease prognosis in patients with advanced ovarian cancer who received neoadjuvant dose-dense weekly paclitaxel and carboplatin (dd-TC) therapy.MethodsWe retrospectively investigated patients with advanced epithelial ovarian, tubal, or peritoneal carcinoma treated at our hospital from July 2004 to October 2014. Patients received dd-TC therapy as NAC followed by interval debulking surgery (IDS). Specimens resected during IDS were divided into 4 groups based on pathological response: grade 1, most tumor cells appeared to be viable; grade 2a, most tumor cells had disappeared, whereas the remaining tumor cells were vacuolated or degenerated; grade 2b, small numbers of viable tumor cells were observed; and grade 3, small aggregations of macrophages were seen.ResultsSixty-eight patients were enrolled. The median number of NAC cycles was 3 (range, 2–6), and 51 patients (75.0%) achieved complete resection at IDS. Regarding pathological response, 7 (10.3%) patients were classified as grade 1, 11 (16.2%) as grade 2a, 46 (67.7%) as grade 2b, and 4 (5.9%) as grade 3. In univariate and multivariate analyses, grades 2b and 3 pathological responses were significant favorable prognostic factors for progression-free survival (P = 0.028; hazard ratio, 0.48; 95% confidence interval, 0.26–0.92).ConclusionsAlthough the pathological complete response rate to NAC was low in this study, both complete and good pathological responses to NAC might be favorable prognostic factors for PFS in patients with advanced ovarian cancer who receive dd-TC.

Abstract Most advanced ovarian cancer patients experience recurrence and develop resistance to platinum-based agents. However, the diagnosis of platinum resistance based on platinum-free interval is not always accurate and timely. In this study, we employed laser ablation inductively coupled plasma mass spectrometry to visualize platinum distribution in the tissues at the time of interval debulking surgery following neoadjuvant chemotherapy. Twenty seven patients with advanced high grade serous ovarian cancer were enrolled. Two distinct patterns of platinum distribution were observed. Type A (n = 16): platinum accumulation at the adjacent stroma but little in the tumor; type B (n = 11): even distribution of platinum through tumor and adjacent stroma. Type A was significantly correlated with worse prognosis (P = 0.031). Patients classified in type A and treated with platinum-based adjuvant chemotherapy after operation were significantly shorter period of recurrence after last platinum-based chemotherapy (P = 0.020) and diagnosed with “platinum-resistant recurrence”. Treatment with non-platinum-based chemotherapy after operation could be effective for the patients who were classified in type A. Our data indicate that the platinum resistance can be predicted prior to recurrence with platinum distribution. Thus, we will be able to select more appropriate adjuvant chemotherapy, which may possibly lead to improve patient’s prognosis.

5580 Background: Ovarian cancer has a different prognosis between early (I and II) and advanced stage (III and IV). The mechanism of disease progression is unknown, but patients with advanced disease may have a higher propensity for seeding of the abdominal cavity early in the disease process than those with early stage. Theoretically if this is so, then patients with advanced stage should have smaller sized tumors than patients with early stage. Methods: This was a retrospective chart review of patients in the tumor registry in 2003 to 2006. Patients had epithelial ovarian cancer, other cell types were excluded. Only cases with documentation of surgical and pathologic staging and measured dimensions on pathologic specimen were included. Patient stage and all available dimensions measured on diseased ovaries were recorded. The dimensions for each patient were averaged into a single dimension for that patient, and then these measurements were totaled and averaged. Results: There were 110 patients analyzed: 85 with advanced disease, 25 with early stage. The average measurement was 4.8 cm in advanced disease, and was 10.7 cm in early stage disease. This difference was statistically significant (p < 0.001). Conclusions: Overall, patients with early stage ovarian cancer have diseased ovaries that are more than twice as large as those found in advanced disease. This finding supports the fact that early versus advanced ovarian cancer are 2 separate disease processes. Early stage grows locally and does not disseminate, and advanced stage disseminates while the tumor is still relatively small. Theoretically there may be a factor that separates these 2 into different diseases, where advanced disease patients have a substance produced by their tumor that allows for early dissemination, and early stage lacks this substance and only grows locally. Basic science research comparing the tissue microarrays of early versus advanced stage disease may be able to identify this difference. If the difference is found, perhaps therapy can be targeted against this difference. No significant financial relationships to disclose.

Background: Recent studies showed a relevant role of hematogenous spread in ovarian cancer and the interest of circulating tumor cells (CTCs) monitoring as a prognosis marker. The aim of the present study was the characterization of CTCs from ovarian cancer patients, paying special attention to cell plasticity characteristics to better understand the biology of these cells. Methods: CTCs isolation was carried out in 38 patients with advanced high-grade serous ovarian cancer using in parallel CellSearch and an alternative EpCAM-based immunoisolation followed by RT-qPCR analysis to characterize these cells. Results: Epithelial CTCs were found in 21% of patients, being their presence higher in patients with extraperitoneal metastasis. Importantly, this population was characterized by the expression of epithelial markers as MUC1 and CK19, but also by genes associated with mesenchymal and more malignant features as TIMP1, CXCR4 and the stem markers CD24 and CD44. In addition, we evidenced the relevance of TIMP1 expression to promote tumor proliferation, suggesting its interest as a therapeutic target. Conclusions: Overall, we evidenced the utility of the molecular characterization of EpCAM+ CTCs from advanced ovarian cancer patients to identify biomarkers with potential applicability for disseminated disease detection and as therapeutic targets such as TIMP1.

IntroductionEpithelial ovarian cancer is recognized to be heterogeneous but is currently treated with a single treatment strategy. Successful patient stratification of emerging chemotherapy agents is dependent upon the availability of reliable biomarkers indicative of the entire tumor.AimThe aim of this study was to evaluate intertumor and intratumor heterogeneity within a series of epithelial ovarian cancer using homologous recombination (HR) DNA repair status.MethodsPrimary cultures generated from ascites and solid tumor from multiple intra-abdominal sites were characterized by their morphology and expression of protein markers. Results were compared with Formalin fixed paraffin embedded tissue pathology.Homologous recombination function was determined by quantification of nuclear Rad51 foci. Growth inhibition (sulforhodamine B) assays were used to calculate the GI50 for cisplatin and rucaparib.ResultsAscites with matched solid tumor were cultured from 25 patients.Concordance in functional HR status between ascites and solid tumor subcultures was seen in only 13 (52%) of 25 patients. Heterogeneity in HR status was seen even in patients with homogeneous histological subtype. Homologous recombination defective cultures were significantly more sensitive to cisplatin and rucaparib.Additionally, intertumor and intratumor heterogeneity was seen between the expression of epithelial and ovarian markers (EpCAM, cytokeratin, CA125, MOC-31, and vimentin). There was no relationship between heterogeneity of HR functional status and antigen expression.ConclusionsIntertumor and intratumor functional HR heterogeneity exists that cannot be detected using histological classification. This has implications for biomarker-directed treatment.

Abstract Background: Ovarian cancer is the most lethal gynecological cancer which is characterized by extensive peritoneal implantation metastasis and malignant ascites. Despite advances in diagnosis and treatment in recent years, the five-year survival rate is only 25 - 30%. Therefore, developing multifunctional nanomedicine with abilities of promoting apoptosis and inhibiting migration on tumor cells would be a promising strategy to improve the antitumor effect.Methods and results: In this study, we developed a novel ACaT nanomedicine composed of alendronate, calcium ions and cyclin-dependent kinase 7 (CDK7) inhibitor THZ1. With the average size of 164 nm and zeta potential of 12.4 mV, the spherical ACaT nanoparticles were selectively internalized by tumor cells and effectively accumulated in the tumor site. Results of RNA-sequencing and in vitro experiments showed that ACaT promoted tumor cell apoptosis and inhibited tumor cell migration by arresting the cell cycle, increasing ROS and affecting calcium homeostasis. Weekly intraperitoneally administered of ACaT for 8 cycles significantly inhibited the growth of tumor and prolonged the survival of intraperitoneal xenograft mice.Conclusion: In summary, this study presents a new self-assembly nanomedicine with favorable tumor targeting, antitumor activity and good biocompatibility, providing a novel therapeutic strategy for advanced ovarian cancer.
