Abstract
Peritoneal spread is frequent in gastric cancer (GC) and a palliative condition. After failure to systemic chemotherapy (sCTx) remaining therapeutic options are very limited. We evaluated the feasibility and efficacy of locoregional chemotherapy (RegCTx) in peritoneal metastatic GC. In total, 38 (23 male and 15 female) patients with peritoneal metastatic GC after failure of previous sCTx and unresectable disease were enrolled in this study. Using the hypoxic abdominal stop-flow perfusion, upper abdominal perfusion and intraarterial infusion technique in total 114 cycles with Cisplatin, Adriamycin and Mitomycin C were applied. No significant procedure related toxicity was noticed- especially no Grade 3 or 4 toxicity occurred. With the RegCTx approach a median overall survival of 17.4 months was achieved. Patients who had undergone previously resection of the GC the median overall survival was even better with 23.5 months. RegCTx is a promising, safe and efficient approach in diffuse metastatic GC. The evaluation of RegCTx in the setting of multimodal treatment approach at less advanced stages is also warranted.

Enhanced therapeutic index of liposomal doxorubicin Myocet locally delivered by fibrin gels in immunodeficient mice bearing human neuroblastoma. Pharmacol Res 2021; 163:105294. [PMID: 33217536 DOI: 10.1016/j.phrs.2020.105294] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 09/30/2020] [Accepted: 11/02/2020] [Indexed: 12/12/2022]
Abstract
Caelyx and Myocet are clinically used liposomal forms of doxorubicin (Dox). To explore ways to improve their therapeutic index, we have studied their activity in vitro and in vivo when locally delivered by fibrin gels (FBGs). In vivo local toxic and anti-tumour activities of loaded FBGs were assessed in two immunodeficient mouse orthotopic human neuroblastoma (NB) models after application in the visceral space above the adrenal gland, either still tumour-bearing or after tumour removal. In parallel, in vitro assays were used to mimic the in vivo overlaying of FBGs on the tumour surface. FBGs were prepared with different concentrations of fibrinogen (FG) and clotted in the presence of Ca2+ and thrombin. The in vitro assays showed that FBGs loaded with Myocet possess a cytotoxic activity against NB cell lines generally greater than those loaded with free Dox or Caelyx. In vivo FBGs loaded with Myocet showed lower general and local toxicities as compared to gels loaded with Caelyx or free Dox, and also to free Dox administered i.v. (all treatments with Dox at 2.5 mg/Kg). The anti-tumour activity, evaluated in the two mouse orthotopic NB models of adjuvant and neo-adjuvant therapy, resulted in a better performance of FBGs loaded with Myocet compared to the other local (FBGs loaded with Caelyx or free Dox) or systemic (free Dox) treatments (administered at 2.5 and 5 mg/Kg Dox). Specifically, the application of FBGs at 40 mg/mL in the adjuvant model caused 92 % tumour volume reduction, while by the neo-adjuvant application of FBGs at 22 mg/mL a re-growing tumour volume reduction of 89 % was obtained. Taken together, our in vitro and in vivo results indicate a significantly higher activity for the FBGs loaded with Myocet. In particular, the lower toicity coupled with the higher anti-tumour activity on both the local treatment modalities strongly suggest a better therapeutic index when Myocet is administered through FBGs. Therefore, FBGs loaded with Myocet may be considered as a possible new tool for the loco-regional treatment of NB or even other tumour histotypes treatable by loco-regional chemotherapy.

Abstract
UNLABELLED In photodynamic therapy (PDT), the light activation of a photosensitizer leads to the generation of reactive oxygen species that can trigger various mechanisms of cell death. Harnessing this process within cancer cells enables minimally invasive yet targeted cancer treatment. With this rationale, here we demonstrate tumor-targeted delivery of a highly hydrophobic photosensitizer Pc 4 loaded within biocompatible poly(ethylene glycol)-poly(ɛ-caprolactone) block co-polymer micelles. The micelles were surface-modified with epidermal growth factor receptor (EGFR)-targeting GE11 peptides for active targeting of EGFR-overexpressing cancer cells, in vitro. Pc 4-loaded EGFR-targeted micelles were incubated with EGFR-overexpressing A431 epidermoid carcinoma cells for various time periods, to determine Pc 4 uptake by epifluorescence microscopy. The cells were subsequently photoirradiated, and PDT-induced cell death for various incubation periods was determined by MTT assay and fluorescence Live/Dead assay. Our results indicate that active EGFR targeting of the Pc 4-loaded micelles accelerates intracellular uptake of the drug. Consequently, this enhances the PDT-induced cytotoxicity within shorter time periods. FROM THE CLINICAL EDITOR Photodynamic cancer therapy using Pc 4, a light activated and highly hydrophobic photosensitizer is demonstrated in this paper in vitro. Pc 4 was delivered in block-copolymer micelles surface-modified with GE11 peptides targeting EGFR-overexpressing cancer cells.
