ABSTRACT: Adjuvant treatments following breast-conserving surgery (BCS) are essential to reduce the risk of local recurrences in patients with breast cancer. However, current adjuvant treatments are based on ionizing radiation, which brings radiation-induced damage and amplifies the risk of death. Here we explore the feasibility of using non-ionizing light to induce photothermal therapy as an adjuvant treatment to BCS. In an orthotopic breast cancer mice model, we demonstrate that adjuvant photothermal therapy (aPTT) decreases the incidence of local recurrences after BCS with no expense of cosmetic outcome. In comparison with conventional photothermal therapy, the technique used in aPTT provides more uniformly distributed light energy and less risk of skin burns and local recurrences. Overall, this work represents a departure from the traditional concept of using PTT as an alternative to surgery and reveals the potential of using PTT as an alternative to adjuvant radiation therapy, which is valuable especially for patients susceptible to radiation damage.

Since the vast majority of local recurrences that developed in patients who did not receive WBRT are in the vicinity of the primary tumor, WBRT is supposed to exert its primary effect on the residual malignant cells left in the tumor beds.8−10 Thus, it is reasonable to explore other modalities of treatment which are more localized to the tumor beds as alternatives to WBRT. Recently, serval phase II and III clinical trials show accelerated partial breast irradiation (APBI),7,11 a radiation therapy that focuses specifically on the part of the breast where the tumor is removed, is as effective as WBRT for patients with early stage breast cancer. The use of APBI also shortens the course of treatment and reduces the radiation dose to healthy

reast cancer is the most common cancer diagnosed in women, and 61% of patients are diagnosed at the early stage in the United States.1 For these patients, breastconserving surgery (BCS) is strongly recommended by the NCCN guidelines as a good and safe alternative to total mastectomy for its equivalent therapeutic effect and better cosmetic result.2 BCS is usually followed by whole-breast radiotherapy (WBRT) to lower the incidence of local recurrences after BCS and increase the survival of patients in the long term.3,4 However, the ionizing radiation used in WBRT amplifies the risk of death due to the radiation-induced heart disease and secondary malignant disease.4,5 For these concerns, up to 50% of patients in the United States who are clinically eligible for BCS choose to undergo total mastectomy with the goal to omit radiation therapy.6,7 © 2017 American Chemical Society

tissues.12−14 Nonetheless, APBI is still a technique based on ionizing radiation and cannot completely omit the damage to healthy tissues from high-energy radiation. Therefore, it is in great demand to develop adjuvant therapies based on nonionizing irradiation for patients qualified for the treatment with BCS. Photothermal therapy (PTT) is an emerging therapeutic modality utilizing the heat generated by certain kinds of nanoparticles upon near-infrared (NIR) light irradiation to kill cancers.15−21 As compared with radiation therapy, the advantages of PTT include: (1) free of ionizing radiation damage and (2) dualselectivity from the tumor-targeting accumulation of nanoparticles and the spatially confined delivery of light. It is noted that the penetration depth of the NIR light in tissues is about 1 cm,22 which is close to the margin width required irradiation in the APBI treatment.13,23 Thus, PTT may serve as an alternative to the adjuvant APBI treatment to control local recurrences postsurgery with no radiation damage and superior tumor selectivity. However, to the best of our knowledge, there are no previous reports to explore the feasibility of using PTT as an adjuvant treatment followed BCS. Herein, we report the application of PEGylated gold nanobipyramids (GBP-PEG) in adjuvant photothermal therapy (aPTT) followed BCS in an orthotopic breast cancer mice model. The production of gold nanobipyramids (GBPs) with high purity is realized by synthetic approaches very recently.24−26 Previous reports showed GBPs have stronger and narrower localized surface plasmonic resonance (LSPR) than other shapes of gold nanoparticles,27,28 thus they are supposed to convert light energy into heat more efficiently. Our results showed that the obtained GBP-PEG had superior photothermal conversion efficacy over that of nanorods. More important, we found the GBP-PEG-mediated aPTT significantly decreased the likelihood of local recurrences after BCS

with no expense of cosmetic outcomes. In contrast, BCS and conventional photothermal therapy (cPTT) alone failed to control the local recurrences. The risk of adverse cosmesis was even escalated in mice treated by cPTT because of the overheating of healthy tissues resulting from maldistributed light energy.

RESULTS First, PEGylated gold nanobipyramids (GBP-PEG) were prepared, purified, and characterized. Transmission electronic microscopy (TEM) images display GBP-PEG have a uniform length of 77.2 ± 3.3 nm and width of 23.0 ± 1.8 nm (Figure 1a,b). The selective area electronic diffraction (SAED) pattern of GBP-PEG additionally revealed their high crystallinity (Figure S1). UV−vis absorbance showed the LSPR of GBPPEG peaked at 808 nm. Successful purification was identified by the dramatically reduced absorbance in the spectral region from 500 to 600 nm (Figure 1c). Zeta potential measurement exhibited a decrease of surface charge from +39.0 ± 1.4 mV to −2.0 ± 2.1 mV after PEGylation, implying the attached surfactants on crude GBPs were replaced by mPEG-SH molecules. Dynamic light scattering (DLS) measurement showed the hydrodynamic diameter of GBP-PEG is 41.7 ± 1.0. This diameter is not consistent with the size measured on TEM images because of the anisotropic structure of nanobipyramids. The size of GBP-PEG remained stable in PBS for up to 1 week (Figure S2), suggesting the dense PEG layer protects GBP-PEG from aggregation. Thermal images show the temperature of GBP-PEG solutions increases rapidly upon 808 nm laser irradiation at 1 W·cm−2 and the maximum equilibrium temperature of solutions is correlated directly to the concentration of GBP-PEG. As for the ultrapure water itself, no significant change of temperature was observed during the irradiation (Figure 1d,e). It is noted that the photothermal conversion efficacy of GBP-PEG is higher than 663

(b) Cell viability of MDA-MB-231 and MCF 10A cells after incubation with various concentrations of GBP-PEG for 48 h without laser irradiation. P values 50% of the intensity of the primary tumor. Conventional Photothermal Therapy Procedure. Tumorbearing mice were i.v. injected with 150 μL of GBP-PEG (3.75 mg/ kg) and anesthetized with isoflurane after 24 h. The tumor was then irradiated by an 808 nm laser at 2.5 W·cm−2 for 10 min. The laser was output from an optical fiber with a divergence angle of 16°. The temperature of mice during treatment was monitored by an IR camera. Breast-Conserving Surgical Procedure. Tumor-bearing mice were anesthetized by inhaling isoflurane. The skin over the tumors was sterilized by 70% alcohol. A 5−10 mm sagittal cut was performed medial to the skin−tumor interface, and the mammary fat pad was exposed. The exposed encapsulated tumor was carefully separated and removed. No skin or muscle was removed to mimic the breast-

the cosmetic outcome, aPTT might be particularly useful for patients who are susceptible to radiation damage, such as those with collagen vascular disease or that underwent radiation therapy before. To mimic the clinical situation, the surgical procedure we used in this study was established according to the standard for BCS in the management of invasive breast cancer.47 The incision was placed near the tumor with adequate size to remove the tumor in one piece. The tumors were removed with a rim of healthy tissue without excessive sacrifice of surrounding tissues. The muscles and skin were preserved. The success of gross tumor removal was defined as a resection with microscopically tumor-negative margin according to the consensus guideline on margins for BCS from the Society of Surgical Oncology and American Society for Radiation Oncology.23 All of the surgery was done by one operator under the guidance of an experienced surgeon to minimize the variations in the extent of breast resection. Compared to the rate of local recurrences in patients undergoing BCS, the likelihood of local recurrences was significantly higher in our animal model, which is probably due to the immune deficiency of the nude mice and the absence of adjuvant systematic treatment like chemotherapy.

CONCLUSIONS In summary, we reported the GBP-PEG-mediated PTT as an adjuvant therapy following breast-conserving surgery in an orthotopic breast cancer mice model. The GBP-PEG exhibited superior photothermal conversion efficacy and excellent biocompatibility. The GBP-PEG-mediated aPTT can decrease the incidence of local recurrences after surgery without worsening the cosmetic results. The strategy outlined here represents a departure from the traditional concept of using PTT as an alternative to surgery and reveals the potential of using PTT as an alternative to adjuvant radiation therapy, which is valuable especially for patients with collagen vascular disease or that underwent radiation therapy before. The comparison between adjuvant radiation therapy and aPTT on animal models is underway to fully understand the effect of aPTT in vivo. METHODS Materials. Gold(III) chloride trihydrate (HAuCl44·3H2O), silver nitrate (AgNO3), sodium borohydride (NaBH), ascorbic acid, trisodium citrate, and thiazolyl blue tetrazolium bromide (MTT) were purchased from Sigma-Aldrich. Cetyltrimethylammonium chloride (CTAC), cetyltrimethylammonium bromide (CTAB), hydrogen peroxide (H2O2), and ammonium hydroxide (NH3·H2O) were purchased from Aladdin Chemical. Methoxy-PEG-thiol (mPEGSH, MW = 5000 Da). MDA-MB-231/Luc (breast cancer cell lines expressing luciferase) was purchased from Shanghai Bioray Biotechnology, Co. Ltd. Synthesis of GBP-PEG. Crude GBP were obtained by a modified method reported in previous studies. Briefly, the gold seeds were synthesized by adding 150 μL of 0.01 M freshly prepared ice-cold NaBH4 in the mixture of 125 μL of 0.01 M HAuCl4, 250 μL of 0.01 M citrate sodium, and 9.625 mL of ultrapure water under stirring at 1400 rpm. After the mixture turned to pink, the gold seeds were aged for at least 2 h without stirring. The growth solution was prepared by adding 2000 μL of 0.01 M HAuCl4, 400 μL of 0.01 M AgNO3, 800 μL of 1 M HCl, and 320 μL of freshly prepared 0.1 M ascorbic acid to 40 mL of 0.1 M CTAB solution. Then 150 μL aged seed solution was gently mixed with the growth solution by inversion. The reaction solution was left in 30 °C water bath undisturbed overnight. 668

ACS Nano conserving surgery. The incision was closed by clips. The removed tumors were fixed for hematoxylin and eosin (H&E) staining. Adjuvant Photothermal Therapy Procedure. Tumor-bearing mice were i.v. injected with 150 μL of GBP-PEG (3.75 mg/kg) 24 h prior surgery. When the incision was closed, the surgical area was irradiated by an 808 nm laser at 1 W·cm−2 for 5 min. The laser was transformed to plane wave by a homemade lens system to gain a uniform intensity distribution in the irradiated area (Figure S13). The size of irradiation field was controlled by an aperture stop. The temperature of mice during treatment was monitored by an IR camera. Biodistribution Studies in Vivo. Tumor-bearing mice were i.v. injected with 150 μL of GBP-PEG (3.75 mg/kg). The mice were sacrificed 6, 24, and 48 h postinjection (three mice per group). Tumors and major organs including heart, liver, spleen, lung, and kidney were collected. All of the samples were weighed and digested to estimate the gold concentration by inductively coupled plasma atomic emission spectroscopy (ICP-AES) measurement. Biocompatibility Studies in Vivo. Healthy female nude mice were randomly divided into two groups (six mice per group) and followed by i.v. injection of 150 μL of saline or GBP-PEG (3.75 mg/ kg). The mice were sacrificed 18 days later. The blood and major organs of mice were collected for biochemical examinations and H&E staining. Statistical Analysis. Data are expressed as mean ± SD. For the in vitro experiments and biocompatibility studies, the comparison between two groups was calculated by two-tailed Student’s t test. For the in vivo experiments, statistical significance was determined by one-way ANOVA for Gaussian distributed data followed by Tukey post hoc statistical test or by Kruskal−Wallis test for non-Gaussian distributed data followed by Dunn’s post hoc statistical test. To compare the trend of local tumor recurrences, a Kaplan−Meier survival curve statistical analysis was performed and followed by a logrank test. To compare the rate of skin scar formation, statistical significance was calculated by Fisher’s exact test. Differences between all groups were considered significant at a value below 0.05 except for the log-rank test, in which the significance threshold was adjusted to 0.0167 by Bonferroni correction.
