RESUMEN

Hyperthermic intraperitoneal chemotherapy's role in ovarian cancer remains controversial, hindered by limited understanding of hyperthermia-induced tumor cellular changes. This limits developing potent combinatory strategies anchored in hyperthermic intraperitoneal therapy (HIPET). Here, we perform a comprehensive multi-omics study on ovarian cancer cells under hyperthermia, unveiling a distinct molecular panorama, primarily characterized by rapid protein phosphorylation changes. Based on the phospho-signature, we pinpoint CDK1 kinase is hyperactivated during hyperthermia, influencing the global signaling landscape. We observe dynamic, reversible CDK1 activity, causing replication arrest and early mitotic entry post-hyperthermia. Subsequent drug screening shows WEE1 inhibition synergistically destroys cancer cells with hyperthermia. An in-house developed miniaturized device confirms hyperthermia and WEE1 inhibitor combination significantly reduces tumors in vivo. These findings offer additional insights into HIPET, detailing molecular mechanisms of hyperthermia and identifying precise drug combinations for targeted treatment. This research propels the concept of precise hyperthermic intraperitoneal therapy, highlighting its potential against ovarian cancer.

RESUMEN

Background: Human breast carcinoma is a complex disease, affecting 1 in 8 women worldwide. The seriousness of the disease increases when the definite cause of the disease remains obscure, thus making prognosis challenging. Researchers are emphasizing on adapting more advanced and targeted therapeutic approaches to address the multifaceted impacts of the disease. Hence, modern multi-omics systems have gained popularity among clinicians, as they offer insights into the genomic, pharmacogenomic, metabolomic, and microbiomic factors, thus allowing researchers to develop targeted and personalized approaches for breast cancer prevention and early detection, and eventually improving patient outcomes. Aim: The primary focus of this study is to elucidate, through the integration of multi-omics research findings, the inherent molecular origins of diverse subtypes of breast cancer and to evaluate the effectiveness of these findings in reducing breast cancer-related mortalities. Methods: Thorough investigation was conducted by reviewing reputable and authoritative medical journals, e-books, and online databases dedicated to cancer research. The Mendelian inheritance in man database (OMIM) was used to scrutinize specific genes and their respective loci associated with the development of different types of breast cancer. Results: Our present research revealed the holistic picture of sundry molecular, genomic, pharmacogenomic, metabolomic, and microbiomic features of breast cancer. Such findings, like genetic alterations in highly penetrant genes, plus metabolomic and microbiomic signatures of breast cancer, unveil valuable insights and show great potential for multi-omics research in breast oncology. Conclusion: Further research in omics sciences pertaining to breast cancer are at the forefront of shaping precise treatment and bolstering patient survival.

RESUMEN

OBJECTIVES: To examine guideline-concordant care (GCC) for ovarian cancer, identify its predictors, and evaluate the associations between GCC and survival, health care expenditures, and utilization. STUDY DESIGN: A retrospective cohort study using Surveillance, Epidemiology, and End Results-Medicare data. METHODS: Women aged 66 to 90 years who received a diagnosis of stage II or higher epithelial ovarian cancer during 2011-2015 were included (N = 3237). The National Comprehensive Cancer Network clinical practice guidelines were used to identify GCC. Logistic regression was conducted to identify predictors of GCC, a Cox proportional hazards model was used to examine mortality, and generalized linear models were used to examine mean monthly Medicare expenditures and health care utilization. RESULTS: Approximately 57% of women received GCC and 11.6% of women did not receive any cancer-specific treatment. Women who were relatively older (adjusted odds ratio [AOR], 0.272; 95% CI, 0.210-0.351), had Census tract income of $50,000 or less (AOR, 0.709; 95% CI, 0.551-0.913), had a psychiatric condition (AOR, 0.655; 95% CI, 0.464-0.923), and had adenocarcinoma histology (AOR, 0.564; 95% CI, 0.441-0.721) were significantly less likely to receive GCC. Race/ethnicity was not found to be a significant predictor of GCC. Women who received surgery only or chemotherapy only had a significant higher hazard of all-cause mortality and ovarian cancer-specific mortality compared with those who received GCC (surgery only: adjusted HR [AHR], 2.307; chemotherapy only: AHR, 1.802). Receiving chemotherapy only was associated with 45% (P < .0001) higher mean monthly expenditures compared with those who received GCC. CONCLUSIONS: Non-GCC was associated with worsened survival, higher health care utilization, and increased expenditures. It is important to highlight that women who received GCC were associated with better survival likely due to favorable prognostic clinical factors.

RESUMEN

Rectal cancer is the most common tumor of digestive tract. For female patients, ovarian metastasis ranks the second place in intraperitoneal organ metastasis. Its symptoms are occult, easily missed and insensitive to systemic treatment, so the prognosis is poor. Surgery is the treatment of choice for patients with rectal ovarian metastases, whether R0 resection is possible or not, and reducing tumor load is associated with better prognosis. With the continuous development of hyperthermic intraperitoneal chemotherapy (HIPEC), tumor reduction can reach the cellular level, which can significantly improve survival. Prophylactic ovariectomy remains a controversial issue in patients at high risk of ovarian metastasis. In this review, we summarize the diagnosis, treatment and prevention strategies of rectal cancer ovarian metastases, hoping to provide some reference for clinical practice.

RESUMEN

PURPOSE OF REVIEW: Integrative oncology (IO) services provide a wide range of complementary medicine therapies, many of which can augment the beneficial effects of conventional supportive and palliative care for patients with ovarian cancer. This study aims to assess the current state of integrative oncology research in ovarian cancer care. RECENT FINDINGS: We review the clinical research both supporting the effectiveness of leading IO modalities in ovarian cancer care as well as addressing potential safety-related concerns. There is growing amount of clinical research supporting the use of IO and implementation of integrative gynecological oncology models of care within the conventional supportive cancer care setting. Additional research is still needed in order to create clinical guidelines for IO interventions for the treatment of female patients with ovarian cancer. These guidelines need to address both effectiveness and safety-related issues, providing oncology healthcare professionals with indications for which these patients can be referred to the IO treatment program.

RESUMEN

Objective:Magnetic fluid hyperthermia (MFH) is a still experimental technique found to have a potential application in the treatment of cancer. The method aims to reach around 41 °C-47 °C in the tumor site by exciting magnetic nanoparticles with an externally applied alternating magnetic field (AMF), where cell death is expected to occur. Applying AMFs with high spatial resolution is still a challenge. The AMFs from current and prospective MFH applicators cover relatively large areas; being not suitable for patients having metallic implants near the treatment area. Thus, there will be a clinical need for smaller magnetic field applicators. To this end, a laparoscopic induction heater (LIH) and a transrectal induction heater (TRIH) were developed.Methods:Miniature 'pancake' coils were wound and inserted into 3D printed enclosures. Ovarian (SKOV-3, A2780) and prostate (PC-3, LNCaP) cancer cell lines were used to evaluate the instruments' capabilities in killing cancer cellsin vitro, using Synomag®-D nanoparticles as the heat mediators. NIH3T3 normal cell lines were also used with both devices to observe if these cells tolerated the conditions applied.Results:Magnetic field intensities reached by the LIH and TRIH were 42.6 kA m-1at 326 kHz and 26.3 kA m-1at 303 kHz, respectively. Temperatures reached in the samples were 41 °C by the LIH and 43 °C by the TRIH. Both instruments successfully accomplished killing cancer cells, with minimal effects on normal cells.Conclusion:This work presents the first line of handheld medical induction heaters and have the potential to be a complement to existing cancer therapies.Significance:These instruments could enable the development of MFH modalities that will facilitate the clinical translation of this thermal treatment.

RESUMEN

Ovarian cancer (OC) remains a clinical challenge for its difficulty in early diagnosis and insensitivity to treatments. Gut microbiota modulate multiple carcinoma progression through immunoregulation. The relationship between OC and gut microbiota has not been fully characterized. We find that the feces of patients with OC demonstrate different characteristics from benign controls. After fecal microbiota transplantation (FMT) from patients with OC into OC-bearing mice, the tumor development accelerates. Further, an Akkermansia supplementation with FMT significantly suppresses OC progression in mice. RNA sequencing of tumors shows that T cell activation pathways are upregulated after Akkermansia supplementation with FMT. Moreover, acetate accumulation accompanies Akkermansia abundance elevation, which is associated with enhanced interferon γ (IFNγ) secretion of CD8+ T cells and also its tumor-killing property. This work highlights the importance of protective gut microbiome in immune surveillance of OC, which connects accumulation of acetate and the cytotoxic function of CD8+ T cells by increasing IFNγ secretion.

RESUMEN

Photothermal therapy (PTT), as a noninvasive and local treatment, has emerged as a promising anti-tumor strategy with minimal damage to normal tissue under spatiotemporally controllable irradiation. However, the necrosis of cancer cells during PTT will induce an inflammatory reaction, which may motivate tumor regeneration and resistance to therapy. In this study, polyoxometalates and a chloroquine diphosphate (CQ) co-loaded metal-organic framework nanoplatform with hyaluronic acid coating was constructed for efficient ovarian cancer therapy and anti-inflammation. Our results demonstrated that this nanoplatform not only displayed considerable photothermal therapeutic capacity under 808 nm near-infrared laser, but also had an impressive anti-inflammatory capacity by scavenging reactive oxygen species in the tumor microenvironment. CQ with pH dependence was used for the deacidification of lysosomes and the inhibition of autophagy, cutting off a self-protection pathway induced by cell necrosis-autophagy, and achieving the synergistic treatment of tumors. Therefore, we combined the excellent properties of these materials to synthesize a nanoplatform and explored its therapeutic effects in various aspects. This work provides a promising novel prospect for PTT/anti-inflammation/anti-autophagy combinations for efficient ovarian cancer treatment through the fine tuning of material design.

RESUMEN

OBJECTIVES: We report the 20-year experience of the largest Australian unit performing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for ovarian cancer and reflect on learning opportunities. METHODS: A retrospective review of all cases of CRS for ovarian cancer at St George Peritonectomy Unit from Jan 1998 to Jan 2018 was performed. Prospectively collected data include age, stage, histology, disease extent (PCI), completeness of cytoreduction (CC score), HIPEC regime, 30-day surgical morbidity, disease recurrence, and death. Survival was computed using Kaplan-Meier method and analysed using log-rank tests and Cox-proportional hazards models. RESULTS: Forty-one women with advanced ovarian cancer (11 primary stage III/IV, 30 recurrent) underwent CRS, 29 (71%) with HIPEC. Most (68%) had high-volume disease (PCI > 15). In 98%, CC0/CC1 (residual < 2.5 mm) was achieved. Fourteen (34%) had grade 3/4 complications, 1 patient (2%) died within 30 days and 2 patients (5%) died within 90 days. Progression-free and median overall survival was 30.0 and 67.0 months for primary cancer, and 6.7 and 18.1 months for recurrent cancer. Survival was associated with platinum-sensitivity, PCI ≤ 15, and CC score 0, but not HIPEC. CONCLUSION: This study reports outcomes for patients with advanced ovarian cancer patients treated in an Australian centre offering CRS and HIPEC. Whilst survival and morbidity outcomes were good for primary disease, they were poorer than predicted from the literature for cases of recurrent disease. The incorporation of evidence-based predictors of survival and multidisciplinary input are essential to achieve the best survival outcomes.

RESUMEN

Background: Epithelial ovarian cancer (EOC) remains the leading cause of gynecologic cancer death worldwide due to the high recurrence rate. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is an alternative modality for platinum-sensitive recurrent EOC. The latest studies demonstrate homologous recombination-related (HRR) mutation status increases the sensitivity to platinum-based chemotherapy drugs in EOC. However, the molecular analysis of recurrent EOC patient benefits from HIPEC is unknown. Thus, we aimed to evaluate the efficacy and safety of CRS combined with HIPEC for platinum-sensitive in recurrent EOC with HRR mutation. Methods: This is a phase III randomized controlled clinical trial in patients with platinum-sensitive recurrent EOC. Participants were divided into 2 groups based on the HRR mutation status and randomized to receive CRS + HIPEC. The patients then received periodic chemotherapy and follow-up. Results: The primary objective of this study was to evaluate the effect of CRS + HIPEC compared to CRS alone in patients with a platinum-sensitive recurrent EOC stratified for HRD status. We hypothesize that the addition of HIPEC to CRS improves the progression-free survival (PFS) of platinum-sensitive recurrent EOC patients with HRR mutation compared with patients without HRR mutation. Conclusion: Recurrent EOC has a poor prognosis due to implantation and metastasis in the abdominal cavity. Intraperitoneal chemotherapy reduced seeding by removing free tumor cells. HIPEC utilizes physical and biological properties to significantly increase the clearance rate of tumors. Van Driel WJ et al proposed that HIPEC using platinum-based chemotherapy improves the survival of patients with ovarian cancer. HRR mutation, as a common pathogenic mutation in ovarian cancer, has a predictive effect on the platinum sensitivity of ovarian cancer patients. Whether lobaplatin-based HIPEC will play a greater role in ovarian cancer patients with HRR mutations is currently unknown.

RESUMEN

Ovarian cancer is the first cause of death by gynecological cancer. Most of the patients are diagnosed with peritoneal carcinomatosis that represents a therapeutic challenge. Its management implies maximal cytoreductive surgery with survival benefit. Over the last three decades, several strategies of intra-peritoneal chemotherapy have been investigated. This includes intra-peritoneal adjuvant chemotherapy that is used mainly in North America, hyperthermic intraperitoneal chemotherapy (HIPEC) and more recently pressurized intraperitoneal aerosol chemotherapy (PIPAC). In the current article, we review the evidence in favor of each therapeutic approach, and we propose treatment algorithms depending on the clinical situation of ovarian cancer patients: upfront, platinum-sensitive and platinum-resistant relapse.


Le cancer de l'ovaire est la première cause de décès par cancer gynécologique. La plupart des patientes sont diagnostiquées au stade de carcinose péritonéale qui représente un défi thérapeutique. Sa prise en charge chirurgicale implique une cytoréduction maximaliste. Au cours des 30 dernières années, plusieurs stratégies de chimiothérapie intrapéritonéale ont été testées afin d'améliorer le contrôle de la carcinose péritonéale. Il s'agit des chimiothérapies intrapéritonéale adjuvante utilisée surtout en Amérique du Nord, hyperthermique intrapéritonéale (CHIP) et intrapéritonéale pressurisée en aérosols (PIPAC). Dans cet article, nous reprenons les données de la littérature sur chacune de ces trois approches thérapeutiques et proposons des algorithmes décisionnels selon la situation clinique des patientes traitées pour un cancer de l'ovaire : au diagnostic, récidive platine-sensible et platine-résistante.

RESUMEN

INTRODUCTION: Small-bowel involvement in patients with ovarian cancer has been strongly correlated with the possibility of cytoreduction and thus with survival. The main objective of this study was to evaluate the prognostic significance of small-bowel involvement in patients undergoing optimal-complete interval cytoreductive surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC). METHODS: We included a series of patients diagnosed with stage IIIC-IVA (pleural effusion) high-grade serous epithelial ovarian cancer and in whom CRS + HIPEC was indicated after neoadjuvant systemic chemotherapy (NACT). The study period extended from January 2008 to January 2020, with a minimum follow-up of 12 months from the inclusion of the last patient. A multivariate analysis using Cox regression allowed us to identify the variables that were independently related to disease-free survival. RESULTS: A total of 144 patients were selected, 13 (9%) of whom were excluded from the analysis, because their disease was considered unresectable. The study included a series of 131 patients with a median age of 62 years (34-79 years) and a median Peritoneal Cancer Index (PCI) calculated during surgery of 9 (1-35). The median PCI of bowel areas 9-12 (SB-PCI) was 3 (1-10). Performance of a CC-1 cytoreduction (HR: 1.93, 95% CI: 1.02-3.64, p = 0.042) and SB-PCI greater than 3 (HR: 2.25, 95%CI: 1.13-4.48, p = 0.21) were independent factors associated with shorter disease-free survival. CONCLUSION: Small-bowel involvement, even in patients with a macroscopically complete resection, showed a correlation with worse prognostic outcomes and could be considered as a variable in the postoperative management of these patients.

RESUMEN

Ovarian cancer is one of the most fatal gynecological cancers. For most ovarian cancer patients, nutritional risk or malnutrition may accompany them for life. Regular nutritional risk screening, timely nutritional assessment and necessary nutritional treatment play an extremely important role in the process of comprehensive treatment of ovarian cancer. The nutritional status and influence of ovarian cancer patients, preoperative screening and assessment of nutritional risk, preoperative and postoperative nutritional treatment indicate that nutritional treatment of ovarian cancer is one of the key factors in the treatment of cancer. We have summarized the status and progress of nutritional support therapy for ovarian cancer. We are aimed to improve the understanding of the impact of nutritional support therapy for ovarian cancer and to guide the clinical work.

RESUMEN

BACKGROUND: Treatment outcomes remain poor in recurrent platinum-resistant ovarian cancer. Enadenotucirev, a tumor-selective and blood stable adenoviral vector, has demonstrated a manageable safety profile in phase 1 studies in epithelial solid tumors. METHODS: We conducted a multicenter, open-label, phase 1 dose-escalation and dose-expansion study (OCTAVE) to assess enadenotucirev plus paclitaxel in patients with platinum-resistant epithelial ovarian cancer. During phase 1a, the maximum tolerated dose of intraperitoneally administered enadenotucirev monotherapy (three doses; days 1, 8 and 15) was assessed using a 3+3 dose-escalation model. Phase 1b included a dose-escalation and an intravenous dosing dose-expansion phase assessing enadenotucirev plus paclitaxel. For phase 1a/b, the primary objective was to determine the maximum tolerated dose of enadenotucirev (with paclitaxel in phase 1b). In the dose-expansion phase, the primary endpoint was progression-free survival (PFS). Additional endpoints included response rate and T-cell infiltration. RESULTS: Overall, 38 heavily pretreated patients were enrolled and treated. No dose-limiting toxicities were observed at any doses. However, frequent catheter complications led to the discontinuation of intraperitoneal dosing during phase 1b. Intravenous enadenotucirev (1×1012 viral particles; days 1, 3 and 5 every 28-days for two cycles) plus paclitaxel (80 mg/m2; days 9, 16 and 23 of each cycle) was thus selected for dose-expansion. Overall, 24/38 (63%) patients experienced at least 1 Grade ≥3 treatment-emergent adverse event (TEAE); most frequently neutropenia (21%). Six patients discontinued treatment due to TEAEs, including one patient due to a grade 2 treatment-emergent serious AE of catheter site infection (intraperitoneal enadenotucirev monotherapy). Among the 20 patients who received intravenous enadenotucirev plus paclitaxel, 4-month PFS rate was 64% (median 6.2 months), objective response rate was 10%, 35% of patients achieved stable disease and 65% of patients had a reduction in target lesion burden at ≥1 time point. Five out of six patients with matched pre-treatment and post-treatment biopsies treated with intravenous enadenotucirev plus paclitaxel had increased (mean 3.1-fold) infiltration of CD8 +T cells in post-treatment biopsies. CONCLUSIONS: Intravenously dosed enadenotucirev plus paclitaxel demonstrated manageable tolerability, an encouraging median PFS and increased tumor immune-cell infiltration in platinum-resistant ovarian cancer. TRIAL REGISTRATION NUMBER: NCT02028117.

RESUMEN

Cell-membrane-coated nanoparticles are widely studied due to their inherent cellular properties, such as immune escape and homologous homing. A cell membrane coating can also maintain the relative stability of nanoparticles during circulation in a complex blood environment through cell membrane encapsulation technology. In this study, we fused a murine-derived ID8 ovarian cancer cell membrane with a red blood cell (RBC) membrane to create a hybrid biomimetic coating (IRM), and hybrid IRM camouflaged indocyanine green (ICG)-loaded magnetic nanoparticles (Fe3O4-ICG@IRM) were fabricated for combination therapy of ovarian cancer. Fe3O4-ICG@IRM retained both ID8 and RBC cell membrane proteins and exhibited highly specific self-recognition of ID8 cells in vitro and in vivo as well as a prolonged circulation lifetime in blood. Interestingly, in the bilateral flank tumor model, the IRM-coated nanoparticles also activated specific immunity, which killed homologous ID8 tumor cells but had no effect on B16-F10 tumor cells. Furthermore, Fe3O4-ICG@IRM showed synergistic photothermal therapy, resulting in the release of whole-cell tumor antigens by photothermal-induced tumor necrosis, which further enhanced antitumor immunotherapy for primary tumor and metastatic tumor by activating CD8+ cytotoxic T cells and reducing regulatory Foxp3+ T cells. Together, the biomimetic Fe3O4-ICG@IRM nanoparticles showed synergistic photothermal-immunotherapy for ovarian cancer.

RESUMEN

ABSTRACT: Women with ovarian cancer are reported to fatigue over time. Moderate to severe levels of cancer-related fatigue is fluent in Han Chinese patients with cancer. Comprehensive Cancer Network guidelines are recommending exercise and cognitive behavioral therapy to reduce cancer-related fatigue. Exercise is an easy, cost-effective, and non-pharmacological approach. The objective of the study was to evaluate the effectiveness of nurse-led exercise and cognitive-behavioral care against nurse-led usual care in Han Chinese women of ovarian cancer regarding cancer-related fatigue, depressive symptoms, and sleep quality.Han Chinese women with moderate to severe levels of cancer-related fatigue have received 30 minutes, 5 times/week nurse-led exercise and 60 min/week cognitive-behavioral care (EC cohort, n = 118) or nurse-led usual care regarding educations and recommendations only (UC cohort, n = 126) or have not received nurse-led exercise, cognitive-behavioral care, educations, and recommendations (NC cohort, n = 145) between and after chemotherapy cycles. The Piper Fatigue Scale, the Zung Self-rating Depression Scale, and Pittsburgh Sleep Quality Index questionnaires were evaluated at the start and the end of non-pharmacological treatment.At the end of treatment as compared to the start of treatment, only women of EC cohort had decrease Piper Fatigue Scale (5.40 ±â€Š1.49/woman vs 6.06 ±â€Š1.49/woman, P < .0001, q = 4.973) and Zung Self-rating Depression Scale score (48.67 ±â€Š4.24/woman vs 49.93 ±â€Š4.29/woman, P = .001, q = 3.449). Also, at the end of treatment, as compared to the start of treatment, only women of EC cohort have increased Pittsburgh Sleep Quality Index score (14.76 ±â€Š2.18/woman vs 13.94 ±â€Š2.90/woman, P = .045, q = 3.523). Only exercise and cognitive-behavioral care were successful in a decrease in the numbers of women with depression (the Mandarin Chinese version of the Zung Self-rating Depression Scale score >53, 32 vs 16, P = .015).Nurse-led exercise and cognitive-behavioral care can help Han Chinese women with ovarian cancer to decrease cancer-related fatigue and depression. Also, it can improve the quality of sleep.Evidence Level: 4.Technical Efficacy: Stage 5.
