          Abstract.

          Significance

          This third biennial intraoperative molecular imaging (IMI) conference shows how optical contrast agents have been applied to develop clinically significant endpoints that improve precision cancer surgery.

          Aim

          National and international experts on IMI presented ongoing clinical trials in cancer surgery and preclinical work. Previously known dyes (with broader applications), new dyes, novel nonfluorescence-based imaging techniques, pediatric dyes, and normal tissue dyes were discussed.

          Approach

          Principal investigators presenting at the Perelman School of Medicine Abramson Cancer Center’s third clinical trials update on IMI were selected to discuss their clinical trials and endpoints.

          Results

          Dyes that are FDA-approved or currently under clinical investigation in phase 1, 2, and 3 trials were discussed. Sections on how to move benchwork research to the bedside were also included. There was also a dedicated section for pediatric dyes and nonfluorescence-based dyes that have been newly developed.

          Conclusions

          IMI is a valuable adjunct in precision cancer surgery and has broad applications in multiple subspecialties. It has been reliably used to alter the surgical course of patients and in clinical decision making. There remain gaps in the utilization of IMI in certain subspecialties and potential for developing newer and improved dyes and imaging techniques.

          Second near-infrared photothermal materials for combinational nanotheranostics

          This review summarizes the recent development of second near-infrared photothermal combinational nanotheranostics for cancer, infectious diseases and regenerative medicine. Second near-infrared photothermal therapy (NIR-II PTT, 1000–1500 nm) has recently emerged as a new phototherapeutic modality with the advantages of deeper penetration, less energy dissipation and minimal normal-tissue toxicity over traditional first NIR PTT (750–1000 nm). However, suboptimal photothermal conversion and limited therapeutic efficacy remain the major challenges for NIR-II PTT. With the convergence in materials science, nanomedicine and biology, multifunctional NIR-II photothermal inorganic or organic materials have been extensively developed to combine NIR-II PTT with other therapeutic modalities for improved efficacies in treating life-threatening diseases including cancer and infection. This review summarizes the recent advances of NIR-II photothermal combinational theranostics pertinent to chemotherapy, immunotherapy, radiotherapy, and photodynamic, sonodynamic, chemodynamic, gene, gas, ionic, vascular and magnetothermal therapy. Potential obstacles and perspectives for future research and clinical translation of this new theranostic modality are also discussed.

            Latest developments in molecular tracers for fluorescence image-guided cancer surgery

            Real-time intraoperative guidance is essential during oncological surgery for complete and safe tumour resection. Fluorescence imaging in the near-infrared spectrum has shown potential for guiding surgeons during complex interventions. Recently, there has been a shift towards the use of fluorescence contrast agents for molecular imaging. The first targeted fluorescent agents, of which most consist of approved therapeutic antibodies conjugated to a fluorescent dye, have been evaluated in several early-phase clinical trials. Moreover, advances in protein engineering and drug design have led to the development of a variety of tracers suitable for molecular fluorescence image-guided surgery. In this Review, we discuss preclinical and clinical evidence, ongoing clinical trials, and the latest developments in the field of molecular near-infrared tracers for fluorescence-guided cancer surgery.

              Long-term results of a prospective randomized trial of adjuvant brachytherapy in soft tissue sarcoma.

              This trial was performed to evaluate the impact of adjuvant brachytherapy on local and systemic recurrence rates in patients with soft tissue sarcoma. In a single-institution prospective randomized trial, 164 patients were randomized intraoperatively to receive either adjuvant brachytherapy (BRT) or no further therapy (no BRT) after complete resection of soft tissue sarcomas of the extremity or superficial trunk. The adjuvant radiation was administered by iridium-192 implant, which delivered 42 to 45 Gy over 4 to 6 days. The two study groups had comparable distributions of patient and tumor factors, including age, sex, tumor site, tumor size, and histologic type and grade. With a median follow-up time of 76 months, the 5-year actuarial local control rates were 82% and 69% in the BRT and no BRT groups (P = .04), respectively. Patients with high-grade lesions had local control rates of 89% (BRT) and 66% (no BRT) (P = .0025). BRT had no impact on local control in patients with low-grade lesions (P = .49). The 5-year freedom-from-distant-recurrence rates were 83% and 76% in the BRT and no BRT groups (P = .60), respectively. Analysis by histologic grade did not demonstrate an impact of BRT on the development of distant metastasis, despite the improvement in local control noted in patients with high-grade lesions. The 5-year disease-specific survival rates for the BRT and no BRT groups were 84% and 81% (P = .65), respectively, with no impact of BRT regardless of tumor grade. Adjuvant brachytherapy improves local control after complete resection of soft tissue sarcomas. This improvement in local control is limited to patients with high-grade histopathology. The reduction in local recurrence in patients with high-grade lesions is not associated with a significant reduction in distant metastasis or improvement in disease-specific survival.
