Abstract Background Talaporfin sodium photodynamic therapy (tPDT) is an effective salvage treatment for local failure after chemoradiotherapy for esophageal cancer. Repeated tPDT could also be indicated for local recurrence or residue after the first salvage tPDT. However, the safety and efficacy of repeated tPDT have not been elucidated. Methods We reviewed 52 patients with esophageal cancer who were treated with the first tPDT at Kyoto University Hospital between October 2015 and April 2020. Results Among 52 patients, repeated tPDT after the first tPDT was indicated for 13 patients (25%), of which six had residual tumor, four had local recurrence after complete response (CR) after the first tPDT at the primary site, and six had metachronous lesion. The total session of repeated tPDT was 25; 16 were for primary sites and nine were for metachronous sites. Among them, six patients (46.2%) achieved local (L)-CR and nine lesions (56.3%) achieved lesion L-CR. By session, 10 sessions (40%) achieved L-CR. There were no severe adverse events except for one patient; this patient showed grade 3 esophageal stenosis and perforation after the third tPDT on the same lesion that was previously treated with porfimer sodium photodynamic therapy four times. Conclusion Repeated tPDT could be an effective and safe treatment for local failure even after salvage tPDT for esophageal cancer.

Abstract Background Although surgical resection is the best way for curing cancer, there has been a certain portion of patients who could not undergo surgery because of various reasons. We experienced 9 cases of photodynamic therapy for esophageal cancer patients with inoperable conditions, and investigated the feasibility and safety of photodynamic therapy. Methods Medical records of patients of esophageal cancers who received photodynamic therapies in Korea University Anam Hospital were reviewed retrospectively. Survival, complication rates and treatment results were evaluated. Results A total of 9 patients (all men) with esophageal cancer had been received photodynamic therapy between 2007 and 2015. Average age at the time of treatment was 70.9 (± 4.62, ranging 64 to 78) and average follow-up periods were 18.2 (± 16.59, ranging 3.8 to 53.6). The average Charlson Comorbidity Index (CCI) were 7.3 (± 2.29, ranging 4 to 10). During the follow-up periods, 5 patients died, and only one death was related with the distant metastasis progression. There was one case of skin reaction and no other complications were appeared. There were no complication related deaths. Complete remission of esophageal cancer showed in 6 patients (66.7%) and partial remission showed in 3 patients (33.3%). Two patients with partial remission showed loco-recurrence. One patient with complete remission had to undergo surgery because of preexisting esophageal stenosis. In patients with complete remission, no recurrence was observed. Conclusion Photodynamic therapy is feasible and safe with acceptable rates of complications. For esophageal cancer patients with inoperable condition or refusal of surgery, photodynamic therapy could provide alternative way to treatment.

We present a new family of porphyrin-functionalized coordination star polymers prepared through combination of coordination-driven self-assembly and post-assembly polymerization. Their self-assembly behaviour in water and potential for photodynamic therapy were demonstrated.
