Abstract
In order to achieve long-term and controllable release of anti-tumor drugs at specific sites, temperature/pH responsive nanoparticles encapsulating 5-fluorouracil and methotrexate in situ are prepared through dispersion photopolymerization under green LED irradiation. The physicochemical properties of nanoparticles are characterized by scanning electron microscopy, Fourier transform infrared, dynamic light scattering, thermogravimetric/differential scanning calorimetry, and X-ray diffraction. In vitro drug release at different temperatures and pH values is examined to ascertain the release pattern of two drugs, which can be well described by Korsmeyer-Peppas kinetic model. The cytotoxicity evaluation illustrates that the tumor cells could be more effectively killed by the drug-loaded nanoparticles, and the improved therapeutic effect is attributed to the controllable and sustainable drug release as well as the enhanced cellular uptake. The blood safety and good biocompatibility of nanoparticles are further confirmed by hemolysis assay, indicating the prepared nanoparticles are potential candidates for effective tumor treatment.

Abstract
The present study establishes the phytochemical screening, TLC profiling, in-vitro radical scavenging, and anticancer activities in the successive extracts of whole plant of L. tenuifolia Blume. The preliminary phytochemical screening followed by quantitative estimation of bioactive secondary metabolites revealed higher abundance of phenolic (13.22 ± 0.21 mg GAE/g of extract), flavonoid (8.09 ± 0.13 mg QE/g of extract), and tannin (7.53 ± 0.08 mg GAE/g of extract) contents in ethyl acetate extract of L. tenuifolia which might be attributed to the difference in the polarity and efficacy of the solvents used in successive Soxhlet extraction. Antioxidant activity assessed by DPPH assay and ABTS assay revealed that the ethanol extract exhibited the highest radical scavenging activity with an IC50 value of 18.7 µg/mL and 33.83 µg/mL respectively. FRAP assay carried out on the extracts showed the maximum reducing power exhibited by the ethanol extract with a FRAP value of 1162.30 ± 20.73 FeSO4 E mg/g dw. MTT assay showed that the ethanol extract exhibited promising cytotoxic effect in A431 human skin squamous carcinoma cells with an IC50 value of 24.29 µg/mL. Collectively, our findings strongly suggest that the ethanol extract and its one or more active phytoconstituent can be used as a potential therapeutic to treat skin cancer.

Abstract
While the gold standard treatment for cutaneous squamous cell carcinomas (cSCCs) is surgical removal, there is a risk of infection, cosmetic and functional deficits. Intralesional 5-fluorouracil (5-FU) has been shown to be a potential non-surgical treatment modality for cSCCs in the literature. The aim was to investigate the safety and feasibility of using intralesional 5-FU to treat cSCCs. A literature review was conducted and a retrospective case series analysed patients who commenced intralesional 5-FU treatment for at least one cSCC between 1 January 2018 and 1 January 2019 at a private clinic in Orange, Australia. Inclusion criteria include: at least one cSCC was treated; only intralesional 5-FU was used; and treatment was ceased due to complete or inadequate remission, or adverse effects. There were 15 patients (7 female, 8 male, 60-99 years) and 20 out 21 cSCC lesions (82.6%) cleared while one lesion (4.3%) recurred. Six lesions (26.1%) ulcerated, four lesions became infected (17.4%) and one patient had an allergic reaction. The average number of treatments required for clearance was four (range 1-35), and the average 5-FU dose used was 75 mg (range 50-150 mg). Across 25 studies, 656 out of 708 lesions cleared (92.66%). Adverse effects were self-limiting and mostly well-tolerated. Intralesional 5-FU is an affordable and non-invasive non-surgical treatment modality that appears feasible to use for cSCCs and has a relatively low treatment-associated morbidity. Future clinical trials can help develop a protocol to guide clinicians in its use.

Abstract
Melanoma is one of the deadliest skin tumors, accounting for almost 90% of skin cancer mortality. Although immune therapy and targeted therapy have dramatically changed the prognosis of metastatic melanoma, many patients experience disease progression despite the currently available new treatments. Skin metastases from melanoma represent a relatively common event as first sign of advanced disease or a sign of recurrence. Skin metastases are usually asymptomatic, although in advanced stages, they can present with ulceration, bleeding, and superinfection; furthermore, they can cause symptoms related to compression on nearby tissues. Treatments vary from simple surgery resections to topical or intralesional local injections, or a combination of these techniques with the most recent systemic immune or target therapies. New research and studies should focus on the pathogenesis and molecular mechanisms of the cutaneous metastases of melanoma in order to shed light on the mechanisms underlying the different behavior and prognoses of different patients.

Abstract
PURPOSE The purpose of this study is to assess the dose-dependent immunohistopathological effects of intradermal microneedle-delivered 5-fluorouracil (5-FU) for postincisional wound healing in a murine model. METHODS A prospective experimental study was performed. Twelve hairless mice were randomized into 4 treatment groups for postincisional wound treatment: microneedling with topical saline, or microneeding with topically-applied 5-FU at concentrations of 25 mg/ml, 50 mg/ml, or 100 mg/ml. Two surgical wounds were created on each animal. Combination wound treatments were performed on postoperative days 14 and 28, and cutaneous biopsies were obtained on day 56. Specimens were analyzed by a dermatopathologist, blinded to the treatment group, for collagen thickness, lymphocytic infiltration, histiocytic response, sub-epidermal basement membrane zone thickness, and myofibroblast density. RESULTS Histopathologic evaluation showed increased collagen thickness, lymphocyte infiltration, and granuloma density in the groups undergoing microneedling treatment with 5-FU, compared to saline. Immunohistochemical analysis revealed a trend toward thicker basement membranes with higher concentrations of 5-FU used, reaching statistical significance between controls and those treated with 100 mg/ml 5-FU ( p = 0.0493). A trend toward decreasing myofibroblast density with increasing doses of 5-FU was noted. No postincisional or treatment complications were observed. CONCLUSIONS Our results demonstrate that microneedling is an effective topical subepithelial drug delivery system, and further suggest a beneficial dose-dependent immunomodulatory effect of 5-FU on intermediate wound healing when used in combination with microneedling. We recommend a 5-FU dose at the mid-range 50 mg/ml concentration to simultaneously maximize efficacy and minimize complication risk.

Abstract
BACKGROUND Inflammation of actinic keratoses (AK) was originally described with systemic 5-fluorouracil, and led to the development of topical fluorouracil. Similar observations using different chemotherapeutics may point to other drugs with a potential for repositioning. OBJECTIVE The aim of this systematic review is to evaluate chemotherapeutic agents linked to inflammation-induced cure of AK. METHODS This systematic review was registered in PROSPERO (CRD42022346168) and followed PRISMA guidelines. A comprehensive literature search for eligible original articles written in English and published in peer-reviewed journals until July 13, 2022 was conducted in MEDLINE and Embase. RESULTS 28 articles met inclusion criteria accounting for 36 patients (mean age 68.4 ± 8.3 years) with inflamed AK, exposed to 21 different chemotherapeutic agents - 21/36 (58.3%) received monotherapy and 15/36 (41.7%) received multidrug combinations. Regression was complete in 13/28 (46.4%) and partial in 14/28 (50.0%) of inflamed AK. Cure rates of inflamed AK in multidrug combinations were not superior to monotherapies (p = 0.252), leading to observation that the majority of the former (14/15; 93.3%) encompassed one of five chemotherapeutic agents linked to AK inflammation also as a monotherapy. CONCLUSION Overall, inflammation partially/completely cured AK in 96.4% of patients (27/28). Taxanes, pemetrexed and doxorubicin might have potential for the management of AK.

Abstract
Plenty of factors affect the oncogenesis and progression of colorectal cancer in the tumor microenvironment, including various immune cells, stromal cells, cytokines, and other factors. Chemokine is a member of the cytokine superfamily. It is an indispensable component in the tumor microenvironment. Chemokines play an antitumor or pro-tumor role by recruitment or polarization of recruiting immune cells. Meanwhile, chemokines, as signal molecules, participate in the formation of a cross talk among signaling pathways and non-coding RNAs, which may be involved in promoting tumor progression. In addition, they also function in immune escape. Chemokines are related to drug resistance of tumor cells and may even provide reference for the diagnosis, therapy, and prognosis of patients with colorectal cancer.

Abstract
5-Fluorouracil (5-FU) is an antimetabolite drug widely used for the treatment of skin cancer. Despite its proven efficacy in treating malignancies, its systemic administration is limited due to severe side effects. To address this issue, topical delivery of 5-FU has been proposed as an alternative approach for the treatment of skin cancer, however, the poor permeability of 5-FU through the skin is still a challenge. Here, we introduced a pH-responsive micellar hydrogel system based on deoxycholic acid micelle (DCA Mic) and carboxymethyl chitosan hydrogel (CMC Hyd) to enhance 5-FU efficacy against skin cancer and reduce its systemic side effects by improving its delivery into the skin. The properties of the Mic/Hyd system were determined by Fourier-transform infrared spectroscopy (FT-IR), dynamic light scattering (DLS), zeta sizer, atomic force microscopy (AFM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Drug release studies showed pH-dependent properties of the Hyd. The final formulation was demonstrated to have enhanced anticancer activity than 5-FU against the growth of melanoma cells. The 5-FU@Mic-Hyd could be a promising delivery platform with enhanced efficacy in the management of skin cancer without systemic toxicity.

Efficacy and safety of laser-assisted combination chemotherapy: A follow-up study of treatment with 5-fluorouracil and cisplatin for basal cell carcinoma. Lasers Surg Med 2021; 54:113-120. [PMID: 34865224 DOI: 10.1002/lsm.23497] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 11/10/2021] [Accepted: 11/12/2021] [Indexed: 11/08/2022]
Abstract
BACKGROUND AND OBJECTIVES There is a growing need for effective topical treatments for basal cell carcinoma (BCC). By altering the skin barrier, ablative fractional lasers (AFLs) enhance cutaneous uptake of the synergistic chemotherapeutic agents, cisplatin, and 5-fluorouracil (5-FU). In our recently reported clinical trial, AFL-assisted delivery of cisplatin and 5-FU showed favorable short-term clearance rates of 95% with good cosmetic results at 3 months. This follow-up study assessed sustained tumor clearance, safety, and cosmesis in the same patient cohort, observed 6- and 12-months posttreatment. MATERIALS AND METHODS This follow-up study assessed AFL-assisted cisplatin and 5-FU in low-risk BCC. Among the 18/19 patients who achieved clinical tumor clearance in our 3-months primary trial, all were included for a 6-months follow-up. At 12 months, 17/19 were included due to one 6-month residual. During follow-up visits, treated areas were evaluated for signs of recurrent tumour by clinical inspection and optical coherence tomography (OCT). Residual tumors were confirmed histologically. Cosmetic outcome was evaluated at both follow-up visits by patients and physicians. RESULTS Overall, complete tumor clearance was 89% (17/19) and 79% (15/19) at 6 and 12 months, respectively. Clearance rate for superficial BCCs (sBCCs) 1 year after treatment was 100% (6/6) and lower for nodular BCC (nBCC) at 69% (9/13). Among recurrent tumors, 67% (2/3) had received only a single treatment and all were of the nodular subtype, situated in the head and neck area. All histologically confirmed BCC recurrences were identified by OCT. Cosmetic outcomes were similarly rated "good" or "excellent" by patients and evaluators (p = 0.289 and p = 0.250). Treatment-related local skin reactions were mild and tolerable, consisting of persisting erythema in two patients at the end of the study. Dyspigmentation was commonly observed at both follow-up visits, while the appearance of scarring resolved in the majority of patients between 6 months (56%; 10/18) and 12 months (76%; 13/17). CONCLUSION AFL-assisted cisplatin + 5-FU in double sessions represents an acceptable and safe treatment strategy for low-risk sBCC, while clearance rates following single treatment or for nBCC seem inferior. This intensified topical strategy may be best suited to cases of multiple lesions or in instances where surgical excision or extended courses of at-home therapy is challenging.

Abstract
BACKGROUND Colon cancer treatments include surgery, radiotherapy, and chemotherapy. Chemotherapy using 5-fluorouracil (5-FU) has been widely applied to treat colorectal cancer (CRC). However, it is important to explore the use of chemotherapy drugs in combination with other agents to decrease severe adverse effects. PURPOSE This study aimed to investigate the effects of curcumin in combination with 5-FU on the proliferation, migration, and apoptosis of CRC SW620 cell line both in vitro and in vivo. METHODS Flow cytometry was used to study the effect of curcumin on chemotherapy-induced apoptosis in CRC cells. The mechanism of curcumin's enhanced antitumor effect in vivo was investigated using gene knockdown, TUNEL, western blot, qRT-PCR and immunohistochemistry. RESULTS The results showed a synergistic effect of the two compounds on CRC cells. Considerable reduction in the proliferation and migration of SW620 cells was observed in the combination treatment group. Significantly increased apoptosis rate extended the survival of immunodeficient mice in the combination group as compared to that of the 5-FU group (p < 0.05). The results showed that curcumin significantly inhibited pERK signaling and downregulated L1 expression in SW620 cells. CONCLUSIONS We conclude that curcumin promotes chemosensitivity of CRC cells to 5-FU by downregulating L1 expression. Our findings provide experimental evidence for the synergism between curcumin and 5-FU, which can be utilized in clinical applications for reducing the toxicity and adverse effects of 5-FU.

Abstract
Carrier-free nanodrugs, generated via the straightforward small-molecule self-assembly of anticancer drugs, provide a promising route for cancer chemotherapy. However, their low structural stability, lack of targeting specificity, and poor stimulus responsiveness are still limiting their therapeutic effect. Inspired by Watson-Crick G[triple bond, length as m-dash]C base pairing, the FDA-approved chemo-drug methotrexate (MTX, which can bind with folate receptors) and 5-fluorouracil (5-FU, a DNA/RNA synthetase inhibitor) were adopted for direct assembly into self-recognizing MTX-5-FU nanoparticles via "Watson-Crick-like base pairing"-driven precise supramolecular assembly. Sequentially, our synthesized weak acidity-responsive polyethylene glycol (PEG) was inserted onto the nanoparticle surface to temporarily shield the self-targeting function of MTX and prolong the blood circulation time. Once PEG-MTX-5-FU nanoparticles reached the weakly acidic tumor microenvironment, the PEG corona could be cleaved from their surface and then MTX could be re-exposed to recover its self-recognition ability and significantly elevate tumor cell uptake; furthermore, the de-PEGylated MTX-5-FU nanoparticles could respond to the stronger acidity of lysosome, triggering core disassembly and thus the burst release of both MTX and 5-FU. Further in vitro and in vivo studies consistently confirmed that the nanodrugs exhibited preferable accumulation at the tumor sites with highly synergistic chemotherapeutic effects. The supramolecular recognition-inspired, cascade-triggered self-targeting and controlled release of nanodrugs could be a promising strategy to improve synergistic chemotherapy.

Abstract
Recent studies have demonstrated that aural cholesteatoma features intense DNA turnover in the germinati ve layer of the matrix and an immune response in the wall of the cyst, which trigger a chain reaction. 5-Fluorouracil, an antimetabolitic agent that is also effective topically, was applied to the cyst wall in initial cholesteatoma, in relapsing cholesteatoma (even transtympanically) and in large exudative cavities resulting from attico-antrectomy: in all cases, it inhibited the formation of keratin and reduced the mucous hypersecretion. These results have persisted even after 12 months of suspending treatment.

Abstract
BACKGROUND Cancer treatment in the 21st century has seen immense advances in optical imaging and immunotherapy. Significant progress has been made in the bioengineering and production of immunoconjugates to achieve the goal of specifically targeting tumors. DISCUSSION In the 21st century, antibody drug conjugates (ADCs) have been the focus of immunotherapeutic strategies in cancer. ADCs combine the unique targeting of monoclonal antibodies (mAbs) with the cancer killing ability of cytotoxic drugs. However, due to random conjugation methods of drug to antibody, ADCs are associated with poor antigen specificity and low cytotoxicity, resulting in a drug to antibody ratio (DAR) >1. This means that the cytotoxic drugs in ADCs are conjugated randomly to antibodies, by cysteine or lysine residues. This generates heterogeneous ADC populations with 0 to 8 drugs per an antibody, each with distinct pharmacokinetic, efficacy, and toxicity properties. Additionally, heterogeneity is created not only by different antibody to ligand ratios but also by different sites of conjugation. Hence, much effort has been made to find and establish antibody conjugation strategies that enable us to better control stoichiometry and site-specificity. This includes utilizing protein self-labeling tags as fusion partners to the original protein. Site-specific conjugation is a significant characteristic of these engineered proteins. SNAP-tag is one such engineered self-labeling protein tag shown to have promising potential in cancer treatment. The SNAP-tag is fused to an antibody of choice and covalently reacts specifically in a 1:1 ratio with benzylguanine (BG) substrates, eg, fluorophores or photosensitizers, to target skin cancer. This makes SNAP-tag a versatile technique in optical imaging and photoimmunotherapy of skin cancer. CONCLUSION SNAP-tag technology has the potential to contribute greatly to a broad range of molecular oncological applications because it combines efficacious tumor targeting, minimized local and systemic toxicity, and noninvasive assessment of diagnostic/prognostic molecular biomarkers of cancer.

Abstract
Several case reports and retrospective studies have demonstrated that intralesional methotrexate (MTX) could be a very effective and safe alternative treatment of keratoacanthoma (KA). Here, we report a rapid clinical efficacy of two intralesional MTX injections (total dose 40 mg) that were performed 1 week apart in the treatment of a large KA lesion of the dorsal hand in a 99-year-old woman. The lesion, with a 3-cm major axis diameter and a thickness of 2 cm with a central ulceration had rapidly appeared on the right dorsal hand. A 3-mm punch biopsy confirmed the diagnosis of a well-differentiated KA-type spinous cellular carcinoma. Due to the presence of comorbidities (arterial hypertension and atrial fibrillation) and chronic treatment with antihypertensive and oral anticoagulant drugs, treatment with intralesional MTX was proposed to the patient. Two intralesional MTX injections of 20 mg each were performed 1 week apart. A very fast resolution of the lesion was observed after the first injection. A week after the second injection a full resolution of the skin lesion was observed, with a nearly complete resolution of the central ulceration. The treatment was very well tolerated. No local or systemic side effects were observed. This case report confirms that intralesional MTX could be considered an effective and safe treatment of KA also in very old subjects.

Abstract
Introduction 5-Fluorouracil is a fluoropyrimidine antineoplastic medication that is used to topically treat actinic keratoses. Although local adverse effects to the drug are common and anticipated, distant skin reactions are rare and unexpected. In this case report, we describe a patient who developed seborrheic dermatitis-like eruption at a distant site after topical application of 5-fluorouracil to his arms. Case report A 63-year-old man with actinic keratoses on his arms developed a facial seborrheic dermatitis-like reaction after topically applying 5-fluorouracil 5% cream twice daily to actinic keratoses on his forearms for 7 days. The facial dermatosis resolved shortly after discontinuation of the 5-fluorouracil; upon rechallenge of topical 5-fluorouracil on his arms, the facial seborrheic dermatitis recurred. Discussion Several case reports have been published which describe exacerbations of preexisting seborrheic dermatitis with local topical 5-fluorouracil. Additionally, one case series describes the development of scrotal dermatitis in two patients after distant treatment with 5-fluorouracil. The pathogenesis that causes this distant reaction is unclear. Conclusion We describe a patient with a seborrheic dermatitis eruption after topical application of 5-fluorouracil at a distant site. The etiologic association between the drug and adverse effect was confirmed with multiple cycles of application and discontinuation of the offending agent.

Abstract
Interleukin-6 (IL-6) is a key player in inflammation and the main factor for the induction of acute phase protein biosynthesis. Further to its central role in many aspects of the immune system, IL-6 regulates a variety of homeostatic processes. To interfere with IL-6 dependent diseases, such as various autoimmune diseases or certain cancers like multiple myeloma or hepatocellular carcinoma associated with chronic inflammation, it might be a sensible strategy to target human IL-6 receptor (hIL-6R) presenting cells with aptamers. We therefore have selected and characterized different DNA and RNA aptamers specifically binding IL-6R. These IL-6R aptamers, however, do not interfere with the IL-6 signaling pathway but are internalized with the receptor and thus can serve as vehicles for the delivery of different cargo molecules like therapeutics. We succeeded in the construction of a chlorin e6 derivatized aptamer to be delivered for targeted photodynamic therapy (PDT). Furthermore, we were able to synthesize an aptamer intrinsically comprising the cytostatic 5-Fluoro-2′-deoxy-uridine for targeted chemotherapy. The α6β4 integrin specific DNA aptamer IDA, also selected in our laboratory is internalized, too. All these aptamers can serve as vehicles for targeted drug delivery into cells. We call them charomers—in memory of Charon, the ferryman in Greek mythology, who ferried the deceased into the underworld.

Abstract
5-Fluorouracil (5-Fu) commonly use in the treatment of different kinds of cancer, but limited cellular uptake and death is still a problem. Herein, we report a simple process for the synthesis of pressure-sensitive nanogels that indicate to be appropriate in the delivery of 5-Fu. The hydrogels (Al-CD) prepare by crosslinking of alginate (Al) with modified beta Cyclodextrin (β-CD) as Crosslinker. Next, nanoparticles obtaine by an emulsification method. 5-Fu as model drug loades into the Al-CD nanogels easily by mixing it in aqueous solution with the nanoparticles. The results revealed that the Al-CD nanogels are cytocompatible. They have also a noticeable drug encapsulation (82.1 ±5.7%) while they can release (in vitro controlled) 5-Fu in conditions that imitate the intravascular pressure conditions. These nanogels can rapidly be taken up by HT-29 cells (a colon cell line). In addition, a higher 5-Fu intracellular accumulation and a significant cell death extension by apoptosis mechanism is notice when compare with free 5-Fu. Accordingly, the developed nanogels can be employe as an excellent candidate to overcome the inefficiency of 5-Fu in anticancer treatments and possibly can employe for further evaluation as a chemotherapical agent in applications beyond cancer. © 2017 Wiley Periodicals, Inc.

Abstract
Nanoparticle drug formulations have been extensively investigated, developed, and in some cases, approved by the Food and Drug Administration (FDA). Synergistic combinations of drugs having distinct tumor-inhibiting mechanisms and non-overlapping toxicity can circumvent the issue of treatment resistance and may be essential for effective anti-cancer therapy. At the same time, co-delivery of a combined regimen by a single nanocarrier presents a challenge due to differences in solubility, molecular weight, functional groups and encapsulation conditions between the two drugs. This review discusses cellular and microenvironment mechanisms behind treatment resistance and nanotechnology-based solutions for effective anti-cancer therapy. Co-loading or cascade delivery of multiple drugs using of polymeric nanoparticles, polymer-drug conjugates and lipid nanoparticles will be discussed along with lipid-coated drug nanoparticles developed by our lab and perspectives on combination therapy.

Abstract
BACKGROUND Topical 5-Fluorouracil (5-FU) exhibits suboptimal efficacy for non-melanoma skin cancer, attributed to insufficient intracutaneous penetration. This study investigates the impact of ablative fractional laser (AFXL) at different laser-channel depths on cutaneous 5-FU pharmacokinetics and biodistribution. METHODS In vitro porcine skin underwent AFXL-exposure using a fractional 10,600 nm CO2-laser, generating microscopic ablation zones (MAZ) reaching the dermoepidermal junction (MAZ-ED), superficial-(MAZ-DS), or mid-dermis(MAZ-DM). 5-FU in AFXL-exposed and control skin was measured in Franz diffusion cells at 4 and 24 hours (n = 55). HPLC quantified 5-FU in full-thickness skin, specific skin depths of 100μm-1500μm, and transcutaneous receiver-compartments. Qualitative matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) visualized 5-FU in selected samples. RESULTS Overall, AFXL enhanced and accelerated 5-FU uptake versus unexposed controls, with increased accumulation in deep skin layers (p < 0.01). While total, 24-hour 5-FU uptake in control skin was 0.096 mg/cm3 (0.19% of applied concentration), AFXL delivered up to 4.707 mg/cm3 (MAZ-DM; 9.41% uptake, 49-fold enhancement) (p = 0.002; 24 hours). Indicating accelerated delivery, 5-FU in laser-exposed samples at 4 hours was at least 10-fold that of 24-hour controls (p = 0.002). Deeper laser-channels increased delivery throughout the skin (MAZ-ED vs. MAZ-DM; p<0.01). MALDI-MSI confirmed enhanced, accelerated, deeper and more uniform 5-FU distribution after AFXL versus controls. CONCLUSIONS AFXL offers laser-channel depth-dependent, enhanced and accelerated 5-FU uptake, with increased deposition in deep skin layers.

Abstract
PURPOSE To determine the efficacy of topical 5-fluorouracil 1% (5-FU) as a primary treatment of ocular surface squamous neoplasia (OSSN). DESIGN Retrospective study. PARTICIPANTS Topical 5-FU was used as primary therapy in 44 patients with OSSN. METHODS 5-Fluorouracil 1% administered topically 4 times daily for 1 week followed by a drug holiday of 3 weeks. Patients were identified through a pharmacy database. Patients were excluded if 5-FU was used as adjuvant therapy, if they did not complete therapy, or if they were still actively receiving treatment for OSSN at the time of last follow-up. MAIN OUTCOME MEASURES The primary outcome measures were the frequency of complete resolution with topical 5-FU treatment and the rate of OSSN recurrence. RESULTS Of the 44 patients identified, 32 were men and 12 were women. The mean age was 68 years. Complete resolution of OSSN was noted in 82% of patients (36/44); 18% (8/44) were considered treatment nonresponders. Patients were treated with a median of 4 cycles (range, 2-9 cycles). Nasal location was the only risk factor identified for nonresponse to therapy (P = 0.04). The median follow-up after resolution was 10 months (range, 2-77 months). In the 36 patients who showed complete resolution, 4 experienced tumor recurrence. Recurrence rates at 1 and 2 years were 6% and 15%, respectively, using Kaplan-Meier survival analysis. At least 1 side effect from the medication was reported by 61% of patients (21/44), but only 1 patient discontinued the medication because of intolerance. The most common side effect was pain (n = 17; 39%), followed by tearing (n = 10; 23%), photophobia (n = 6; 14%), itching (n = 4; 9%), swelling (n = 2; 5%), and infection (n = 1; 2%). No long-term complications were reported. CONCLUSIONS 5-Fluorouracil is effective and well tolerated as a primary treatment for OSSN, with 82% of tumors responding completely to therapy.

Abstract
Combination chemotherapy is widely exploited for enhanced cancer treatment in the clinic. However, the traditional cocktail administration of combination regimens often suffers from varying pharmacokinetics among different drugs. The emergence of nanotechnology offers an unparalleled opportunity for developing advanced combination drug delivery strategies with the ability to encapsulate various drugs simultaneously and unify the pharmacokinetics of each drug. This review surveys the most recent advances in combination delivery of multiple small molecule chemotherapeutics using nanocarriers. The mechanisms underlying combination chemotherapy, including the synergistic, additive and potentiation effects, are also discussed with typical examples. We further highlight the sequential and site-specific co-delivery strategies, which provide new guidelines for development of programmable combination drug delivery systems. Clinical outlook and challenges are also discussed in the end.

Abstract
Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts), the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

Abstract
Condyloma acumianata is one of the most common virally transmitted diseases. Its prevalence has increased many fold throughout the world. Because all the currently available treatments yield low cure rates with side effects, the search for a new alternative continues. Topically, 5-fluorouracil (5-FU) has been in used for many years to treat various skin diseases. When applied topically in condyloma acuminata, 5-FU results in low cure rates with high recurrences. Therefore, intralesional 5% 5-FU is being evaluated to determine its therapeutic efficacy in condyloma acuminata.

Abstract
Nanotechnology involves the engineering of functional systems at nanoscale, thus being attractive for disciplines ranging from materials science to biomedicine. One of the most active research areas of the nanotechnology is nanomedicine, which applies nanotechnology to highly specific medical interventions for prevention, diagnosis, and treatment of diseases, including cancer disease. Over the past two decades, the rapid developments in nanotechnology have allowed the incorporation of multiple therapeutic, sensing, and targeting agents into nanoparticles, for detection, prevention, and treatment of cancer diseases. Nanoparticles offer many advantages as drug carrier systems since they can improve the solubility of poorly water-soluble drugs, modify pharmacokinetics, increase drug half-life by reducing immunogenicity, improve bioavailability, and diminish drug metabolism. They can also enable a tunable release of therapeutic compounds and the simultaneous delivery of two or more drugs for combination therapy. In this review, we discuss the recent advances in the use of different types of nanoparticles for systemic and topical drug delivery in the treatment of skin cancer. In particular, the progress in the treatment with nanocarriers of basal cell carcinoma, squamous cell carcinoma, and melanoma has been reported.

Abstract
Surgical modalities-excision, Mohs micrographic surgery, and electrodesiccation with curettage-are the preferred treatments for nonmelanoma skin cancer (NMSC). When used within guidelines, they have cure rates greater than 90%. Despite this, many other treatments have been studied and utilized for NMSC. We present a comprehensive review of the literature on these topical treatments. Photodynamic therapy (PDT) is administered under numerous and significantly varied regimens, and there are a wide range of cure rates reported. Even with aggressive regimens, PDT is not as effective as surgery is, and it is not a first-line therapy for NMSC. The cryotherapy regimen aggressive enough to adequately treat NMSC carries adverse effects and cosmetic outcomes poor enough to negate its usefulness. Topical 5-fluorouracil and imiquimod are efficacious and safe for the treatment of superficial basal cell carcinoma (BCC) but not other BCC subtypes or squamous cell carcinoma. They are self-administered twice daily for several weeks; therefore, patient and tumor selection are vital to ensuring adherence. There are currently insufficient data to support the use of topical diclofenac and ingenol mebutate for NMSC.

Abstract
BACKGROUND Superficial basal-cell carcinoma is most commonly treated with topical non-surgical treatments, such as photodynamic therapy or topical creams. Photodynamic therapy is considered the preferable treatment, although this has not been previously tested in a randomised control trial. We assessed the effectiveness of photodynamic therapy compared with imiquimod or fluorouracil in patients with superficial basal-cell carcinoma. METHODS In this single blind, non-inferiority, randomised controlled multicentre trial, we enrolled patients with a histologically proven superficial basal-cell carcinoma at seven hospitals in the Netherlands. Patients were randomly assigned to receive treatment with methylaminolevulinate photodynamic therapy (MAL-PDT; two sessions with an interval of 1 week), imiquimod cream (once daily, five times a week for 6 weeks), or fluorouracil cream (twice daily for 4 weeks). Follow-up was at 3 and 12 months post-treatment. Data were collected by one observer who was blinded to the assigned treatment. The primary outcome was the proportion of patients free of tumour at both 3 and 12 month follow up. A pre-specified non-inferiority margin of 10% was used and modified intention-to-treat analyses were done. This trial is registered as an International Standard Randomised controlled trial (ISRCTN 79701845). FINDINGS 601 patients were randomised: 202 to receive MAL-PDT, 198 to receive imiquimod, and 201 to receive fluorouracil. A year after treatment, 52 of 196 patients treated with MAL-PDT, 31 of 189 treated with imiquimod, and 39 of 198 treated with fluorouracil had tumour residue or recurrence. The proportion of patients tumour-free at both 3 and 12 month follow-up was 72.8% (95% CI 66.8-79.4) for MAL-PDT, 83.4% (78.2-88.9) for imiquimod cream, and 80.1% (74.7-85.9) for fluorouracil cream. The difference between imiquimod and MAL-PDT was 10.6% (95% CI 1.5-19.5; p=0.021) and 7.3% (-1.9 to 16.5; p=0.120) between fluorouracil and MAL-PDT, and between fluorouracil and imiquimod was -3.3% (-11.6 to 5.0; p=0.435. For patients treated with MAL-PDT, moderate to severe pain and burning sensation were reported most often during the actual MAL-PDT session. For other local adverse reactions, local skin redness was most often reported as moderate or severe in all treatment groups. Patients treated with creams more often reported moderate to severe local swelling, erosion, crust formation, and itching of the skin than patients treated with MAL-PDT. In the MAL-PDT group no serious adverse events were reported. One patient treated with imiquimod and two patients treated with fluorouracil developed a local wound infection and needed additional treatment in the outpatient setting. INTERPRETATION Topical fluorouracil was non-inferior and imiquimod was superior to MAL-PDT for treatment of superficial basal-cell carcinoma. On the basis of these findings, imiquimod can be considered the preferred treatment, but all aspects affecting treatment choice should be weighted to select the best treatment for patients.

Abstract
DNA methylation, catalyzed by methylases, plays a critical role in many biological processes, and many methylases have been regarded as promising targets for antimicrobial drugs. In this work, we report a stimulus responsive, self-regulating anticancer drug release platform, comprising a multifunctional DNA that upon methylation by methyltransferase (MTase) releases 5-fluorouracil (5-Fu) and in turn inhibits subsequent expression of MTase. The multifunctional DNA with anticancer drug are first methylated by DNA adenine methylation (DAM) methyltransferase (MTase) and then cut by the methylation-sensitive restriction endonuclease Dpn I. Removal of duplex from the functional DNA by the methylation/cleavage process will release the anticancer drug, resulting in inhibition of the activity of DAM in turn. Consequently, the enzyme activity of DAM MTase can be self-regulated. Furthermore, we found that the inhibition efficiency of 5-Fu significantly increase as it is functionalized with DNA.

Abstract
Albumin/drug loaded magnetic nanocomposite spheres were fabricated using an oil-in-oil emulsion/solvent evaporation method, and tested on a mouse model (experimental squamous cell carcinoma) to determine the efficacy of the drug delivery system (DDS) on skin cancer. This novel DDS consists of human serum albumin, poly(lactic-co-glycolic acid) (PLGA), 5-fluorouracil (5-Fu), magnetic nanoparticles (10 nm) and fluorescent labeling molecule (diphenylhexatriene). One of the major purposes of using albumin is that it likely provides internal binding to and retention by the inflammatory tissues to reduce the amount of magnetic nanoparticles needed in the drug loaded microspheres (750–1100 nm). This study is aimed at reducing many negative side effects of conventionally used chemotherapy drugs by localizing the chemotherapy drug, controlling the release of the therapeutic agent and encouraging uptake of the DDS into cancerous cells. A group of mice treated with (1) the magnetic targeted DDS were compared to the other three groups, including, (2) DDS without a magnet, (3) 5-Fu local injection, and (4) untreated groups. The fluorescent tracer was ubiquitously identified inside the tumor tissue, and the DDS/tumor tissue boundary presented a leaky interface. The test results clearly showed that the magnetic targeted DDS exhibited significantly superior therapeutic effects in treating the skin cancer, with the increased efficacy to halt the tumor growth.

Abstract
Topical 5-fluorouracil has proved to be a useful therapy since its discovery nearly 50 years ago for the treatment of a range of cancers (e.g. skin, colorectal, breast) and dermatological conditions (e.g. cancerous and precancerous conditions such as actinic keratosis, benign tumors, nail psoriasis, mycosis fungoides, and porokeratoses). As a result of the enduring utility in these conditions, the mechanism of action of 5-fluorouracil has been studied extensively in vivo and in vitro. This review provides an overview of the history and general mechanism of action of 5-fluorouracil and discusses the dermatological implications of the drug, including systemic absorption, selectivity for abnormal skin, targeted delivery, and skin-specific molecular effects. Considerations of 5-fluorouracil treatment in specific dermatological settings are also discussed, as well as recent findings of a role for 5-fluorouracil in the treatment of photoaging.
