Technique For Treatment Of Cancer Research Articles

Dissecting the anti-pancreatic cancer mechanism of gold nanorods mediate photothermal therapy through quantitative proteomics analysis.

Gold nanorods (GNRs) mediated photothermal therapy (PTT) represents a promising technique for cancer treatment, utilizing GNRs in conjunction with near-infrared (NIR) laser irradiation to convert energy into heat. In the present study, we employed PTT to induce apoptosis in pancreatic cancer cells and investigated its underlying mechanisms through quantitative proteomics analysis. Initially, we established that temperatures ranging from 47 to 51°C significantly enhance cellular apoptosis without inducing necrosis. Furthermore, we identified key pathways involved in cell apoptosis, including apoptosis, oxidative stress, and proteasome pathways. Notably, thermal stimulation also resulted in the upregulation of proteins involved in autophagy, which intriguingly contribute to cellular apoptosis via autophagy regulation. Collectively, our findings demonstrate that GNRs-PTT is an effective therapeutic option for pancreatic cancer and provide a theoretical foundation for the clinical application of photothermal therapy. The mass spectrometry proteomics data have been deposited to the ProteomeXchange Consortium (https://proteomecentral.proteomexchange.org) via the iProX partner repository with the dataset identifier PXD058930.

Surgical Outcomes in Laparoscopic Hysterectomy, Robotic-Assisted, and Laparoscopic-Assisted Vaginal Hysterectomy for Uterine and Cervical Cancers: A Systematic Review.

This systematic review aimed to evaluate the outcomes of minimally invasive techniques in gynecological cancer surgery, specifically laparoscopic hysterectomies (LHs), robotic-assisted hysterectomies (RHs), and laparoscopic-assisted vaginal hysterectomies (LAVHs). We conducted a comprehensive search of electronic databases including PubMed and MedLine from January 2010 to August 2024. The search included randomized controlled trials (RCTs) and observational studies. Studies were selected based on inclusion criteria such as a focus on LHs, RHs, or LAVHs, and reporting on key outcomes like recovery rates, overall survival (OS) rates, disease-free survival (DFS), postoperative complications, and surgery time. Exclusion criteria were applied to omit non-randomized studies, non-English publications, and those lacking relevant data. The analysis included 35 studies on gynecological cancers and surgical procedures, conducted across multiple countries. Among them, 8 were RCTs from countries like the Netherlands and Italy, while 20 were retrospective cohort studies from China and the USA. The studies varied in design, cancer type, and participant age, highlighting diverse surgical approaches and the adaptation of minimally invasive techniques in gynecological cancer treatment. LH and RH demonstrated similar oncological safety with comparable OS and DFS rates. RH was associated with reduced blood loss, but longer operative times compared to LH. LAVH showed favorable perioperative outcomes, including shorter hospital stays and faster recovery, but was less frequently studied in advanced-stage cancers. Complication rates were generally lower in minimally invasive surgeries compared to open procedures. The findings support the efficacy of LH and RH as viable alternatives to open surgery, with specific advantages depending on patient and disease characteristics. Minimally invasive techniques in gynecological cancer surgery offer significant advantages in terms of recovery and complication rates. Despite these benefits, further research is needed to confirm their oncological safety and overall effectiveness compared to traditional open surgeries.

Trends of mapping knowledge structure and themes of cancer sonodynamic therapy: a text-mining study.

Sonodynamic therapy (SDT) is a non-invasive cancer treatment technique stemming from photodynamic therapy (PDT) and has garnered escalated interest among researchers in recent years. Numerous aspects of cancer SDT remain contentious, and the global research trajectory within this domain remains insufficiently explored. This study seeks to delineate the comprehensive knowledge framework, developmental trends, and pivotal research focal points concerning cancer SDT. The study retrieved documents on cancer SDT from the Web of Science Core Collection (WoSCC) database spanning from 1 January 2000 to 7 December 2023. Bibliometric visualization was carried out through the utilization of CiteSpace 6.2 R6, VOSviewer 1.6.20, and an online analytical platform. Several bibliometric techniques including co-authorship, co-citation, co-occurrence, cluster, as well as burst analysis were used. A total of 672 publications including 603 articles and 69 reviews were included. The annual publication count exhibited a steady increase over time, notably experiencing a surge, particularly in recent years. In terms of contributors, China has maintained its prominent position with the highest outputs and the most financial support. Chinese Academy of Sciences contributed the most articles. Materials Science was the most investigated research areas. Breast cancer emerged as the most extensively studied tumor, succeeded by sarcoma, hepatocellular carcinoma, melanoma, pancreatic cancer, glioma. According to co-cited references, "harnessing nanomaterial", "sonodynamic precision tumor therapy" and "metal-organic framework" denote the current and emerging research focuses within the field. In tandem with the results from keywords co-occurrence and burst, we identified the following research topics including mechanism of induced cell death (ferroptosis, immunogenic cell death), nano-related research (nanoplatform, nanozymes, nanomaterials, nanosheets, metal-organic frameworks (MOFs), nanocomposites, nanoparticles, nanosonosensitizers, liposomes, nanocarriers), combination therapies (chemodynamic therapy, immunotherapy, radiotherapy, photothermal therapy), and tumor microenvironment (hypoxia, singlet oxygen, oxidative stress), that may remain the research hotspots and receive sustained attention in the near future. For the first time, this bibliometric analysis not only presents a comprehensive portrayal of the knowledge framework, but also delineates shifts in research focal points related to cancer SDT within the last two decades. This systematic summarization offers a comprehensive and lucid comprehension of cancer SDT, providing valuable insights for further investigations in this domain.

Implementation of OSL nanoDot dosimetry in different treatment techniques for head and neck cancer.

In recent decades, technological advances have been made in the field of radiotherapy and with it the emergence of new dosimetric systems for their calibration and commissioning, among other uses. Such is the case of the measurement in the build-up region, where there is no charged-particle equilibrium, which is reflected in the increase in surface dose for patient treatments and potential skin toxicities as a secondary effect. This study utilizes optically stimulated dosemeters (nanoDot) and the radiochromic film (EBT3) to measure skin doses in patients with head and neck cancer who received radiotherapy. Accurately depicting 15 patients with different diagnoses from 3 linear accelerators using 3D, intensity modulated radiation therapy, or volumetric arc therapy/RapidArc technology, these results were compared with those calculated in the treatment planning system (TPS) and obtaining a percentage of variation for the EBT3 ranged from 0.30% to 6.15%, while that observed for the nanoDot was from 0.51% to 4.88%. This difference may be attributed to the reproducibility of placement in patients. Therefore, for clinical use, nanoDot dosemeters are a viable alternative for in vivo dosimetry where rapid validation of planning system results is required.

Oncological and Surgical Outcomes of Oncoplastic Reduction Mammoplasty: A Single-centre Retrospective Study.

Breast-conserving surgery is the preferred treatment for early-stage breast cancer but can often result in unsatisfactory cosmetic outcomes. Oncoplastic surgery aims to improve both oncologic and aesthetic outcomes by combining local excision with plastic surgery techniques. Using breast reduction techniques in breast cancer treatment has been shown to allow for wider margins of excision, leading to enhanced oncological safety and reduced recurrence rates without causing significant asymmetry. This study aimed to analyze the surgical and oncological outcomes of a large cohort of patients undergoing oncoplastic reduction mammoplasty (ORM). A retrospective analysis of postoperative surgical and oncological outcomes of all patients who underwent ORM at a single center between January 2018 and December 2023 was performed. Preoperative patient characteristics, operative and post-operative outcomes were recorded and analyzed. A total of 67 patients that underwent oncologic breast reduction were included in the final analysis - representing a total of 71 ORM, with a mean (SD) age of 53.1 (10.5) years and a mean (SD) BMI of 28.8 (5.9) kg/m2 A superomedial pedicle-based technique was the most frequently used (36.6%), followed by inferior pedicle-based technique (28.1%). A complication rate of 18.3% on the ipsilateral side was observed. Salvage surgery was necessary in five cases (7.0%) due to positive margins - with one patient (1.4%) requiring margin expansion surgery and four (5.6%) a completion mastectomy. This monocentric retrospective study shows that ORM is safe, with a complication rate on par with conventional breast reduction and offers satisfactory oncological outcomes.

In this review, we discuss recent advancements and challenges in various cancer therapies.

Perfusable Plasma‐Activated Saline for Oxidative Stress Delivery to Induce Tumor Cell Apoptosis in Nonmuscle‐Invasive Bladder Cancer

ABSTRACTNonmuscle‐invasive bladder cancer (NMIBC) is a common urologic malignancy. Currently, conventional postoperative perfusion therapy for NMIBC still has high side effects and recurrence rates. Cold atmospheric plasma is a fledgling reactive oxygen species (ROS)–based therapeutic technique for cancer treatment. In this study, we examined the feasibility of plasma‐activated saline (PAS) perfusion for treating NMIBC. The results show that underwater bubble plasma can generate abundant ROS in PAS. In vitro studies revealed that PAS could trigger apoptosis in bladder cancer T24 cells by activating the ROS‐mediated caspase‐3 cascade reaction. In vivo tests revealed that intravesical PAS perfusion effectively inhibited nonmuscle‐invasive T24 tumor growth without significant side effects. Therefore, our results suggest that intravesical PAS perfusion may be a novel treatment option for NMIBC.

Revolutionizing cancer treatment: an in-depth exploration of CAR-T cell therapies.

Cancer is a leading cause of fatality worldwide. Due to the heterogeneity of cancer cells the effectiveness of various conventional cancer treatment techniques is constrained. Thus, researchers are diligently investigating therapeutic approaches like immunotherapy for effective tumor managements. Immunotherapy harnesses the inherent potential of patient's immune system to achieve desired outcomes. Within the realm of immunotherapy, CAR-T (Chimeric Antigen Receptor T) cells, emerges as a revolutionary innovation for cancer therapy. The process of CAR-T cell therapy entails extracting the patient's T cells, altering them with customized receptors designed to specifically recognize and eradicate the tumor cells, and then reinfusing the altered cells into the patient's body. Although there has been significant progress with CAR-T cell therapy in certain cases of specific B-cell leukemia and lymphoma, its effectiveness is hindered in hematological and solid tumors due to the challenges such as severe toxicities, restricted tumor infiltration, cytokine release syndrome and antigen escape. Overcoming these obstacles requires innovative approaches to design more effective CAR-T cells, which require a competent and diverse team to develop and implement. This comprehensive review addresses numerous therapeutic issues and provides a strategic solution while providing a deep understanding of the structural intricacies and production processes of CAR-T cells. In addition, this review explores the practical aspects of CAR-T cell therapy in clinical settings.

MicroRNA-enriched exosome as dazzling dancer between cancer and immune cells.

Exosomes are widely recognized for their roles in numerous biological processes and as intercellular communication mediators. Human cancerous and normal cells can both produce massive amounts of exosomes. They are extensively dispersed in tumor-modeling animals' pleural effusions, ascites, and plasma from people with cancer. Tumor cells interact with host cells by releasing exosomes, which allow them to interchange various biological components. Tumor growth, invasion, metastasis, and even tumorigenesis can all be facilitated by this delicate and complex system by modifying the nearby and remote surroundings. Due to the existence of significant levels of biomolecules like microRNA, exosomes can modulate the immune system's stimulation or repression, which in turn controls tumor growth. However, the role of microRNA in exosome-mediated communication between immunological and cancer cells is still poorly understood. This study aims to get the most recent information on the "yin and yang" of exosomal microRNA in the regulation of tumor immunity and immunotherapy, which will aid current cancer treatment and diagnostic techniques.

Concanavalin: A Loaded Chitosan Nanoparticles Synthesis and Characterization to Inhibit the Proliferation of Lung Cancer

Background Non-small-cell lung cancer is the most ubiquitous malignancy, and the present treatments do not offer the most effective outcomes for therapy. Natural drug therapy, which directly targets tumor cells, is now recognized as a safe technique for cancer treatment. The use of tailored nanoparticles also improves the efficacy of cancer therapy. Purpose To synthesize, characterize, and evaluate the natural drug concanavalin A (ConA) coated with chitosan nanoparticles (ConA-CS NPs) for cytotoxicity against lung cancer cell line (NCI-H358). Methods The current study demonstrates the development of ConA-CS NPs as well as their unique characteristics, anticancer processes, and possible applications in treatment. Using UV–Vis, Fourier transform infrared, X-ray diffraction, field emission scanning electron microscopy, and dynamic light scattering studies, ConA-CS NPs were generated and evaluated. The mitochondrial toxicity test assay was used to examine ConA-CS NP-induced cytotoxicity. Dual (acridine orange/ethidium bromide) staining was performed to examine apoptotic modifications, and mitochondrial membrane potential levels in NCI-H358 cells were examined using the appropriate fluorescence staining assays. Results and Conclusion The use of ConA-CS NPs for enhanced tumor treatment, which combines natural drugs to eradicate the tumor and prevent relapses, is supported by in vitro investigations. The ability of ConA-encapsulated CS NPs to impede human lung carcinoma cell growth has not yet been investigated. Therefore, this investigation may provide a new paradigm for cancer detection and therapy, and the results may surely help to enhance the quality of life for cancer patients.

Cancer Detection and Treatment Using Explainable AI

Cancer detection and treatment is one of the most difficult tasks in modern medicine, hence it has become a priority for researchers to study and develop specific and targeted procedures to patient outcomes. Just recently, the most promising direction is the humanization of explainable AI (XAI) which is a crucial tool for enhancing AI-based decision making in terms of transparency, and understandability. This paper starts out by describing conventional AI techniques for cancer detection and pointing out the informational gaps then delves into XAI's foundations. It explores the role of XAI in cancer detection and treatment by looking at its potential impact on this topic. It first presents the diagnosis of medical imaging data, then a discussion how patients' data will be interpreted by a XAI system and how treatment strategies that are tailored to the individual patient will be developed by optimizing the therapeutic interventions. This paper also presents comprehensive study of the changing side cancer treatment rendered by XAI and explain why further research and cooperation are getting to be of paramount importance in order for it to be fully exploited. Implementation of XAI in screening and treatment techniques for cancer comes to the conclusion of not only revolutionizing precision medicine, but also aiding in the improvement of patient care and will determine oncology practice in future.

Pilot robotic mastectomy in Singapore (PRoMiSing I) study: first safety and feasibility prospective cohort trial in South East Asia.

Robotic mastectomy has been performed worldwide since 2015. The advantages of the robotic approach in nipple-sparing mastectomy have been proven with better visualization and preservation of blood supply to the nipple-areolar complex, with a lower incidence of necrosis. It also allows smaller incisions for both mastectomy and immediate breast reconstruction. To date, no centers in Singapore and Southeast Asia offer robotic mastectomy. We believe that robotic mastectomy is a feasible and safe technique that our population can utilize. This study aimed to ascertain the surgical outcomes and perform a learning curve analysis in patients undergoing robotic mastectomy in a multi-ethnic South East Asian population. A single-arm prospective pilot study of eligible patients aged 21-70 years old with early breast cancer or high-risk patients indicated for risk-reducing mastectomy who were eligible and consented to robotic mastectomy were enrolled in this trial from December 22, 2022 to December 15, 2023. A total of 29 consecutive robotic mastectomies were performed. The mean total operative time was 95±10.2min. The average blood loss was 5.7±1.9ml, and the average length of stay was 1.05 days. The mean mastectomy specimen weight was 251g, and there was no conversion to conventional mastectomy in any case. Furthermore, there were no 30-day morbidity or complications in terms of wound infection requiring intervention, flap, and nipple-areolar complex necrosis, and postoperative hematoma/bleeding requiring intervention. This study contributes to the current evidence that robotic mastectomy is a safe and feasible option and could prove to be a great alternative to conventional mastectomy. Further prospective trials examining the long-term oncological outcomes of robotic mastectomy will be performed to establish the oncologic safety of this technique in breast cancer treatment.

All-in-One Nanohybrids Combining Sonodynamic Photodynamic and Photothermal Therapies.

A wide variety of methods are being developed to ultimately defeat cancer; while some of these strategies have shown highly positive results, there are serious obstacles to overcome to completely eradicate this disease. So, it is crucial to construct multifunctional nanostructures possessing intelligent capabilities that can be utilized to treat cancer. A possible strategy for producing these multifunctional nanostructures is to combine various cancer treatment techniques. Based on this point of view, we successfully synthesized multifunctional HCuS@Cu2S@Au-P(NIPAM-co-AAm)-PpIX nanohybrids. The peculiarities of these thermosensitive polymer-modified and protoporphyrin IX (PpIX)-loaded hollow nanohybrids are that they combine photodynamic therapy (PDT), sonodynamic therapy (SDT), and photothermal therapy (PTT) with an intelligent design. As an all-in-one nanohybrids, HCuS@Cu2S@Au-P(NIPAM-co-AAm)-PpIX nanohybrids were employed in the SDT-PDT-PTT combination therapy, which proved to have a synergistic therapeutic effect for in vitro tumor treatments against breast tumors.

Exploiting the role of O6-methylguanine-DNA-methyltransferase (MGMT) in gastrointestinal cancers.

Gastrointestinal (GI) cancer is a prevalent disease and is recognized as the primary cause of cancer-related mortality globally. Therefore, there is an urgent need for novel diagnostic and treatment approaches for GC. The methylation of the O(6)-methylguanine DNA methyltransferase (MGMT) gene promoter is a significant factor in the development of colorectal cancer (CRC), namely in roughly 30-40% of cases where the cancer has spread. MGMT plays a role in the repair of DNA damage caused by methylating drugs like temozolomide (TMZ) and chloroethylating compounds like carmustine. As a result, it contributes to the resistance of chemotherapy when these agents are utilized. Although MGMT's role in the development of CRC is well established, its prognostic significance remains a subject of debate. Only a limited number of research have been conducted to examine the prognostic significance of MGMT methylation, yielding varying outcomes. This review explores the structural functions and repair processes of MGMT, focusing on the putative structural and functional significance of the N-terminal domain of MGMT. It also investigates the advancement of cancer treatment techniques that specifically target MGMT.

Microwave dielectric properties of normal, fibroelastotic, and malignant human lung tissue

Technological development of microwave treatment and detection techniques for lung cancer requires accurate and comprehensive knowledge of the microwave dielectric properties of human lung tissue. We characterize the dielectric properties of room temperature human lung tissue from 0.5 to 10 GHz for three lung tissue groups: normal, fibroelastotic, and malignant. We fit a two-pole Debye model to the measured frequency-dependent complex permittivity and calculate the median Debye parameters for the three groups. We find that malignant lung tissue is approximately 10% higher in relative permittivity and conductivity compared to normal lung tissue; this trend matches previously reported normal versus malignant data for other biological tissues. There is little contrast between benign lung tissue with fibroelastosis and malignant lung tissue. We extrapolate our data from room temperature to 37 °C using a temperature-dependence model for animal lung tissue and use the Maxwell-Garnett dielectric mixing model to predict the dielectric properties of inflation-dynamic human lung tissue; both approximations correspond with previously reported dielectric data of bovine and porcine lung tissue.

CT-Guided Percutaneous Cryoablation of Breast Cancer: A Single-Center Experience.

This study shall retrospectively evaluate the efficacy and safety of liquid-nitrogen based CT-guided cryoablation (CA) as a minimal-invasive technique for the curative treatment of primary breast cancer. A total of 45 female patients with 56 tumors were treated by CT-guided CA in analgosedation as an outpatient procedure. We used a liquid-nitrogen based system with a single cryoprobe and performed two freeze cycles with an intermediate thawing. The mean tumor diameter was 1.6 ± 0.7 cm. Follow-up was conducted via contrast-enhanced MR images of the breast. No complications were observed in all 56 ablations. Initial complete ablation was achieved in 100% of cases. Four cases of local tumor progression were reported, resulting in a rate of 8.9%, and 6 cases of intramammary distant recurrence at a rate of 13.3%. The extramammary tumor progression was observed in 7 patients at a rate of 15.6%. The mean overall survival was 4.13 years (95% CI: 3.7-4.5). The mean overall progression-free survival was 2.5 years (95% CI: 1.8-3.2) and the mean local progression-free survival was 2.9 years (95% CI: 2.3-3.6). Cryoablation is a safe and effective treatment for primary breast cancer tumors, which can be performed in analgosedation and as an outpatient procedure. However, potential for improvement exists and further evidence is necessary.

Magnetic‐Driven Hydrogel Spiral PVA/Fe3O4 Micromotors for Targeted Photothermal Therapy

AbstractPhototherapy has emerged as a promising technique for cancer treatment, offering high efficiency and minimal side effects. Nevertheless, conventional phototherapy agents suffer from low targetability and inefficient delivery. Here, a novel approach is proposed using helical hydrogel motors fabricated by combining polyvinyl alcohol, melamine, water, and Fe3O4 nanoparticles. These magnetic motors are capable of precise therapy on tumor cells driven by an external magnetic field. By converting light into heat upon near‐infrared illumination, the motors elevate the temperature of the targeted region, resulting in a significant therapeutic effect, with over 60% eradication of HeLa cells achieve under 808 nm near‐ infrared light (1.5 W cm−2). These helical micromotors exhibit excellent movement performance and biocompatibility, facilitating their in vivo applications and contributing to the advancement of biomedicine.

Trends in the surgical treatment for metastatic spinal tumor in Japanese administrative data between 2012 and 2020.

Both cancer diagnosis/treatment modality and surgical technique for the spine have been developed recently. Nationwide trends in the surgical treatment for metastatic spinal tumors have not been reported in the last decades. This study aimed to examine recent trends in the surgical treatment for spinal metastasis and in-hospital patient outcomes using nationwide administrative hospital discharge data. The Diagnosis Procedure Combination database from 2012 to 2020 was used to extract data from patients who underwent surgical procedures for spinal metastasis with the number of non-metastatic spinal surgery at the institutions that have performed metastatic spine surgeries at least one case in the same year. Trends in the surgical treatment for spinal metastasis, patients' demographics, and in-hospital mortality/outcomes were investigated. This study analyzed 10,321 eligible patients with spinal metastasis. The surgical treatment for spinal metastasis increased 1.68 times from 2012 to 2020, especially in fusion surgery, whereas the proportion of metastatic spinal surgery retained with a slight increase in the 2%s. Distributions of the primary site did not change, whereas age was getting older. In-hospital mortality and length of stay decreased over time (9.9-6.8%, p < 0.001; 37-30days, p < 0.001). Postoperative complication and unfavorable ambulatory retained stable and slightly decreased, respectively. During the last decade, surgical treatment for spinal metastasis, especially fusion surgery, has increased in Japan. In-hospital mortality and length of stay decreased. Recent advances in cancer treatment and surgical techniques might influence this trend.

A Hybrid Nanotube Stamp System in Intracellular Protein Delivery for Cancer Treatment and NMR Analytical Techniques.

In contrast to intracellular gene transfer, the direct delivery of expressed proteins is a significantly challenging yet essential technique for elucidating cellular functions, including protein complex structure, liquid-liquid phase separation, therapeutic applications, and reprogramming. In this study, we developed a hybrid nanotube (HyNT) stamp system that physically inserts the HyNTs into adhesive cells, enabling the injection of target molecules through HyNT ducts. This system demonstrates the capability to deliver multiple proteins, such as lactate oxidase (LOx) and ubiquitin (UQ), to approximately 1.8 × 107 adhesive cells with a delivery efficiency of 89.9% and a viability of 97.1%. The delivery of LOx enzyme into HeLa cancer cells induced cell death, while enzyme-delivered healthy cells remained viable. Furthermore, our stamp system can deliver an isotope-labeled UQ into adhesive cells for detection by nuclear magnetic resonance (NMR).
