Abstract

Introduction: The development of nanoparticles as computed tomography contrast agents has increased significantly. However, few reports have been published on the use of silver and platinum nanoparticles as contrast agents. These nanomaterials are a good candidatefor contrast agents because of their high atomic number and high durability against corrosion. Material and Methods: Experimentally, a Nd:YAG laser (1064 nm, 45 m], 10 Hz) was focused on a high-purity metal plate including Ag and Pt plates, which are placed in deionized water medium. Colloidal nanoparticles of Ag and Pt were then mixed to obtain a mixture composition of Ag and Pt with ratios of Ag:Pt of 75:25%, 50:50%, 25:75%,

respectively.The Ag, Pt, and Ag-Pt NPs mixture were then examined as contrast agents in CT scan.

Results: The imaging results of the quantitative analysiswere measured in the Hounsfield Unit(HU), showing 13.5, 12.8, 13.3, 14.1, and 17.3 HU for colloidal 100% AgNPs, colloidal Ag and Pt NPs with volume ratios of Ag:Pt of 75:25%, 50:50%, 25:75%, and colloidal 100%Pt NPs, respectively. Conclusion: Results reveal the highest absorbent power was found in the colloidal contrast agent of Pt NPs 100% is 17.3 HU, followed by the 25:75% Ag-Pt NPs is 14.1 HU. The higher HU value for platinum can be attributed to its

Introduction: Photodynamic therapy (PDT) can be considered as a non-invasive method for cancer treatment. One of the most commonly of a water-soluble dye photosensitizer (PS) used in photothermal therapy (PTT) and PDT is Indocyanine Green (ICG). However, high cytotoxicity in high concentration and instability in aqueous media were limited its application. It was shown that using nanoparticles or plant extracts in combination with PS could improve PDT efficiency. In this study, anti-cancer properties of crocetin (Crt) loaded PLGA (Poly lactic-co-glycolic acid) nanoparticles (NPs) were utilized to increase the PDT efficacy with ICG on the MCF-7 cells.

Material and Methods: Crt was encapsulated into PLGA NPs and its particle size distribution and encapsulation efficiency were evaluated. IC10 of Crt, PLGA-Crt NPs and ICG was determined by MTT assay in MCF-7 cancer cells. At these concentrations, the cells were pre-treated with Crt or PLG-Crt, then treated with ICG and finally exposure to near infrared (NIR) laser with 2.5 W powers at different times. The cells viability was evaluated by the MTT assay.

Results: The findings showed no dark cytotoxicity due to ICG (12.9 μM), Crt or PLGA-Crt alone. But NIR laser irradiation in the presence of ICG after cells pre-treatment by the Crt or PLGA-Crt NPs leads to induce cell death to (61.6 ±7) % and (75.5 ±5) %, respectively (P<0.05).

Conclusion: The results demonstrated that PLGA-Crt NPs in combination with ICG could improve PDT outcomes more efficiently in comparison with Crt and ICG. Therefore, this method could be effective in breast cancer therapy with low cytotoxicity.

Introduction

Photodynamic therapy (PDT) has attracted considerable attention as a non-invasive therapeutic technique for cancer because of low cost, short treatment time and low systemic toxicity properties [1-4]. In this method, a light-sensitive agent named photosensitizer (PS) conducts to cancer cells and after stimulation by specific wavelength, singlet oxygen converts into various reactive oxygen species (ROS) that led to the death of tumor cells [5-8]. The effect of PS on cancer cells could be influenced by different factors such as the type or concentration of Ps [9] and the amount of light radiation [10]. On the other hand, the combination of PDT and a secondary treatment can be designed to increase the effectiveness of PDT [7] and reduce toxicity due to the use of a lower dose of PS. recently, more attention has been focused on the using of plant extracts in combination with PDT for cancer treatment [3, 11]. Another approach to enhance PDT is using nanoparticles (NPs) to improve the solubility of hydrophobic PSs, controlled release and increase the concentration of PSs at desired sites

[12, 13]. Various types of NPs such as liposomes, quantum dots, gold NPs, polymers, micelles, magnetic NPs, dendrimers, and carbon-based NPs have been developed to improve PSs efficiency [12].

One of the most commonly used PS is Indocyanine green (ICG) or 4, 5-Benzoindotricarbocyanine, a tricarbocyanine dye with amphiphilic molecular structure [14, 15]. This PS is approved by the U.S.

Food and Drug Administration (FDA) [10, 16].

Compared to other sensitizers, ICG shows the unique specifications such as strong absorption (between 700 and 800 nm) and emission peaks at the NIR region [10], high accumulation in tumor tissue and water solubility [17, 18]. The problems associated with ICG are high cytotoxicity at high concentration [19] and instability in aqueous media [17].

Recently, the attention to medicinal herbs has been paid, significantly in the treatment of tumors. Saffron, as coloring for foods in plant Crocus sativus L, has been suggested to treat different diseases, especially cancer [20-22]. Crocetin (Crt) is a carboxylic

Introduction: Dose reduction to the duodenum is important to decrease gastrointestinal toxicities in patients with locally advanced pancreatic cancer (LAPC) treated with definitive chemoradiotherapy. We aimed to compare dynamic wave arc (DWA), a volumetric-modulated beam delivery technique with simultaneous gantry/ring rotations passing the waved trajectories, with coplanar VMAT (co-VMAT) with respect to dose distributions in LAPC cases.

Material and Methods: DWA and co-VMAT plans were created for 13 patients with LAPC. The prescribed dose was 45.6 or 48 Gy in 15 fractions. The dose volume indices (DVIs) for target volumes and organs at risk were compared between the corresponding plans. Gamma passing rate, monitor unit (MU), and beam-on time were also compared.

Results: DWA significantly reduced the duodenal V39Gy, V42Gy, and V45Gy by 1.1, 0.8, and 0.2 cm3, and increased the liver mean dose and D2cm3 of the spinal cord planning volume by 1.0 and 1.5 Gy, respectively.

Meanwhile, there was no significant difference in the target volumes except for D2% of PTV (111.5% in DWA vs. 110.5% in co-VMAT). Further, the gamma passing rate was similar in both plans. MU and beam- on time increased in DWA by 31 MUs and 15 seconds, respectively.

Conclusion: DWA generated significantly lower duodenal doses in LAPC cases, albeit with slight increasing liver and spinal cord doses and increasing MU and the beam delivery time. Further evaluation is needed to know how the dose differences would affect the clinical outcomes in chemoradiotherapy for LAPC.

Introduction

Pancreatic cancer has poor prognosis and is one of the leading causes of cancer-related deaths worldwide [1]. Surgical resection is the standard treatment for early stage pancreatic cancer, but 30-35% of patients are in a locally advanced stage upon diagnosis [2].

These patients with locally advanced pancreatic cancer (LAPC) are commonly treated with systemic chemotherapy, but the median overall survival is only 11.9-13.6 months [3]. A previous study on LAPC patients treated with first-line chemotherapy reported that 41% of the patients died without developing any

distant metastases [4]. Chemoradiotherapy plays an important role in the treatment of LAPC [5].

Delivering high doses to the target organ while avoiding the organs-at-risk (OARs) is important in radiotherapy. The pancreas is surrounded by radiosensitive organs, such as the duodenum, stomach, liver, colon, and kidneys. During irradiation to the irregularly shaped target volume using three- dimensional conformal radiation therapy (3D-CRT), it is inevitable for these radiosensitive organs to be irradiated with high doses, thus causing gastrointestinal (GI) toxicities such as ulcer,
