Abstract
Chemotherapy resistance is a bottleneck for ovarian cancer treatment; therefore, revealing its regulatory mechanism is critical. In the present study, we found that prostate tumor overexpressed-1 (PTOV1) was upregulated significantly in ovarian cancer cells and tissues. Patients with high PTOV1 levels had a poor outcome. In addition, PTOV1 overexpression increased CDDP (cisplatin) resistance, while PTOV1 knockdown inhibited CDDP resistance, as determined using cell viability assays, apoptosis assays, and an animal model. Mechanistic analysis showed that PTOV1 increased nuclear factor kappa B (NF-κB) pathway activity, reflected by increased nuclear translocation of its p65 subunit and the phosphorylation of inhibitor of nuclear factor kappa-B kinase subunits alpha and beta, which are markers of NF-κB pathway activation. Inhibition of the NF-κB pathway in PTOV1-overexpressing ovarian cancer cells increased CDDP-induced apoptosis, suggesting that PTOV1 promoted chemotherapy resistance by activating the NF-κB pathway. In summary, we identified PTOV1 as a prognostic factor for patients with ovarian cancer. PTOV1 might be a target for inhibition of chemotherapy resistance.

Systemic complications of the bidirectional intraoperative chemotherapy with intravenous ifosfamide and hyperthermic intraperitoneal chemotherapy (HIPEC) using cisplatin plus doxorubicin. Pleura Peritoneum 2019; 4:20190025. [PMID: 31799375 PMCID: PMC6881663 DOI: 10.1515/pp-2019-0025] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 10/09/2019] [Indexed: 01/23/2023] Open
Abstract
Background Ifosfamide has recently used as the intravenous component of bidirectional intraoperative chemotherapy (BDIC) with hyperthermic intraperitoneal chemotherapy (HIPEC) using cisplatin plus doxorubicin. Little is known about the systemic toxicities of this BDIC regimen. Therefore, this study aimed to assess the toxicities of this treatment. Methods A prospective, cohort study, of patients who underwent the BDIC using intravenous ifosfamide 1,300 mg/m2 and a HIPEC regimen of cisplatin 50 mg/m2 plus doxorubicin 15 mg/m2, at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. Incidences and severity of leukopenia, neutropenia, thrombocytopenia, and erythrocytopenia were assessed over 45 days after BDIC. Nephrotoxicity was assessed according to the RIFLE (Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease) classification system. Haemorrhagic cystitis was assessed by cystoscopy. Results A total of 18 patients were enrolled in the study. Grade 1 leukopenia developed in 11.1% of the patients, with 5.5% developed neutropenia. Thrombocytopenia developed in 61.1% of patients; it was grade 1 or 2 in most patients, but grade 3 in 1 (5.5%) patient. All patients developed erythrocytopenia after BDIC. Leukopenia, neutropenia, and thrombocytopenia resolved without treatment in all patients. Nephrotoxicity developed in 33.3% of the patients. One patient progressed to the End-stage kidney disease classification. No patient developed haemorrhagic cystitis. Conclusions Intravenous ifosfamide combined with HIPEC using cisplatin plus doxorubicin yielded low rates of mild leukopenia. Mild thrombocytopenia was frequent, but severe suppression of platelets was uncommon. Nephrotoxicity developed in one-third of the patients, and haemorrhagic cystitis was absent.

Abstract
OBJECTIVE Leiomyosarcoma of the fallopian tube is a rare malignant gynecologic neoplasm with poor prognosis. It is important to share experience and to collect more cases to improve the understanding of the disease. CASE REPORT We reported three patients with leiomyosarcoma of the fallopian tube who were treated in Fudan University Shanghai Cancer Center (Shanghai, China) from 2012 to 2016. Although the three cases shared the same diagnosis, they varied in the presentations, treatments, and outcomes. CONCLUSION Leiomyosarcoma of the fallopian tube seems to have some particularities in imaging manifestations and immunohistochemical results. It has a progressive course with limited therapeutic options such as surgery, chemotherapy or radiotherapy.

Abstract
Supplemental digital content is available in the text. Objective Primary platinum-resistant epithelial ovarian cancer (EOC) is an area of unmet medical need. There is limited evidence from small studies that platinum-based combinations can overcome “resistance” in a proportion of patients. We investigated the efficacy and toxicity of platinum-based combination chemotherapy in the platinum-resistant and platinum-refractory setting. Methods Epirubicin, cisplatin, and capecitabine (ECX) combination chemotherapy was used at our institution for the treatment of relapsed EOC. From the institutional database, we identified all patients with primary platinum-refractory or platinum-resistant relapse treated with ECX as second-line therapy between 2001 and 2012. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used logistic and Cox regression models to identify predictors of response and survival respectively. Results Thirty-four 34 patients (8 refractory, 26 resistant) were treated with ECX. Response Evaluation Criteria In Solid Tumors (RECIST) response rate was 45%, median progression-free survival (PFS) was 6.4 months, and overall survival (OS) was 10.6 months. Platinum-resistant patients had better outcomes than did platinum-refractory patients (response rate, 54% vs 0%, P = 0.047; PFS 7.2 vs 1.8 months, P < 0.0001; OS 14.4 vs 3 months, P < 0.001). In regression models, time to progression after first-line treatment and platinum-refractory status were the strongest predictors of response and PFS or OS, respectively. Patients with time to progression after first-line treatment longer than 3 months showed PFS and OS of 7.9 and 14.7 months, respectively. Toxicity was manageable, with only 13% of cycles administered at reduced doses. Conclusions Epirubicin, cisplatin, and capecitabine seems to be active in platinum-resistant relapsed EOC with manageable toxicity. Further prospective investigation of platinum-anthracycline combinations is warranted in patients who relapse 3 to 6 months after first-line platinum-taxane treatment.

Oridonin effectively reverses cisplatin drug resistance in human ovarian cancer cells via induction of cell apoptosis and inhibition of matrix metalloproteinase expression.

Abstract
Cisplatin is a first generation platinum‑based chemotherapeutic agent, however, the extensive application of cisplatin inevitably results in drug resistance, which is a major obstacle in cancer chemotherapy. The aim of the present study was to investigate the efficiency of reversing cisplatin‑resistance with the use of combination therapy with oridonin and cisplatin in human ovarian cancer cells, and attempt to reduce the side effects of the therapeutic agents when used alone. The half maximal inhibitory concentration (IC50) values of cisplatin were determined in cisplatin‑sensitive and cisplatin‑resistant ovarian cancer cells using an MTT assay. IC50 values of cisplatin in A2780, A2780/DDP, SKOV3 and SKOV3/DDP cells were significantly decreased in a time‑dependent manner. The antitumor effect of oridonin in A2780/DDP cells was also detected by the MTT assay and the inhibitory effects of oridonin increased in a dose‑ and time‑dependent manner. A2780/DDP cells were treated with 20 µM oridonin in combination with increasing concentrations of cisplatin for 48 h, and the result demonstrated that oridonin synergistically increased the antitumor effects of cisplatin in A2780/DDP cells. Notably, the combination treatment of oridonin and cisplatin effectively reversed cisplatin resistance and the IC50 values were significantly decreased from 50.97 µM and 135.20 to 26.12 µM and 73.00 µM in A2780/DDP and SKOV3/DDP cells at 48 h, respectively. Furthermore, oridonin induced cell apoptosis in a dose‑dependent manner and promoted cell‑cycle arrest at the G0/G1 phase in ovarian cancer cells. Oridonin and cisplatin synergistically increased the cell apoptosis rate of A2780/DDP cells, which was detected by fluorescence‑activated cell sorting analysis. Downregulated expression levels of Bcl‑2 and upregulated the expression of Bax protein were demonstrated by western blot analysis, further indicating increased apoptosis. In addition, the expression levels of matrix metalloproteinase (MMP)‑2 and MMP‑9 decreased in a dose‑dependent manner with oridonin treatment. The results from the present study demonstrated that oridonin exerted a synergistic effect with cisplatin to inhibit proliferation and induce cell apoptosis in cisplatin‑resistant ovarian cancer cells. Thus, combination therapy with oridonin and cisplatin effectively reversed cisplatin resistance in human ovarian cancer cells, which may have useful clinical applications.

Abstract
Cellular pathways are numerous and are highly integrated in function in the control of cellular systems. They collectively regulate cell division, proliferation, survival and apoptosis of cells and mutagenesis of key genes that control these pathways can initiate neoplastic transformations. Understanding these pathways is crucial to future therapeutic and preventive strategies of the disease. Ovarian cancers are of three major types; epithelial, germ-cell, and stromal. However, ovarian cancers of epithelial origin, arising from the mesothelium, are the predominant form. Of the subtypes of ovarian cancer, the high-grade serous tumors are fatal, with low survival rate due to late detection and poor response to treatments. Close examination of preserved ovarian tissues and in vitro studies have provided insights into the mechanistic changes occurring in cells mediated by a few key genes. This review will focus on pathways and key genes of the pathways that are mutated or have aberrant functions in the pathology of ovarian cancer. Non-genetic mechanisms that are gaining prominence in the pathology of ovarian cancer, miRNAs and epigenetics, will also be discussed in the review.
