Abstract
Cancer therapy, especially for tumors near sensitive areas, demands precise treatment. This review explores photodynamic therapy (PDT), a method leveraging photosensitizers (PS), specific wavelength light, and oxygen to target cancer effectively. Recent advancements affirm PDT's efficacy, utilizing ROS generation to induce cancer cell death. With a history spanning over decades, PDT's dynamic evolution has expanded its application across dermatology, oncology, and dentistry. This review aims to dissect PDT's principles, from its inception to contemporary medical applications, highlighting its role in modern cancer treatment strategies.

[PMID: 37455974 PMCID: PMC10338968 DOI: 10.1016/j.heliyon.2023.e17100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 06/05/2023] [Accepted: 06/07/2023] [Indexed: 07/18/2023] Open
Abstract
Background Over the past 30 years, numerous studies have focused on the treatment of cholangiocarcinoma (CCA), and these treatments have greatly evolved. Objectives To better understand the research trends, we evaluated the most influential publications and attempted to identify their characteristics using bibliometric methods. Methods The most influential publications were identified from the Clarivate Analytics Web of Science Core Collection database. The general characteristics of included papers were identified, and the research trends were explored via the bibliometric method. Results The average total number of citations for of the listed publications were 312 (range from 165 to 1922). The highest number of papers were published during period II (2001-2010, n = 50), followed by period III (2011-2020, n = 28), and period I (1991-2000, n = 22). The United States and Germany have made remarkable achievements in this field. Institutionally, Mayo Clinic and Memorial Sloan-Kettering Cancer Center were the leading institutions, with Blumgart and Zhu from the United States being the most influential authors. Close collaboration was established between the leading countries, institutions, and authors. The Annals of Surgery contributed the most to the papers with the highest total number of citations. Surgery predominated during period I (n = 14, 63.6%), with a gradual decline occurring during periods II (n = 19, 41.3%, P = 0.085) and period III (n = 3, 9.4%, P = 0.002). Contrastingly, the number of publications related to systemic therapy has increased significantly since period II and peaked in period III. Conclusions Surgery remains the most important treatment for CCA. However systemic therapy has become a research and clinical application hotspot. These findings will contribute to the translation of treatments for CCA and provide researchers with relevant research directions.

Abstract
Referral to an endoscopist is often done once curative resection is no longer an option for cholangiocarcinoma management. In such cases, palliation has become the main objective of the treatment. Photodynamic therapy and radiofrequency ablation can be performed to achieve palliation, with both procedures associated with improved stent patency and survival. Despite the greatly increased cost and association with photosensitivity, photodynamic therapy allows transmission to the entire biliary tree. In contrast, radiofrequency ablation is cheaper and faster to apply, but requires intraductal contact. This paper reviews both modalities and compares their efficacy and safety for bile duct cancer palliation.

Abstract
BACKGROUND AND AIM Extrahepatic unresectable cholangiocarcinoma carries a dismal prognosis. In addition to biliary drainage by stent placement; photodynamic therapy (PDT) and radiofrequency ablation (RFA) have been tried to prolong survival. In this meta-analysis, we appraise the current known data on the use of PDT, RFA in the palliative treatment of extrahepatic unresectable cholangiocarcinoma. METHODS We searched multiple databases from inception through July 2020 to identify studies that reported on PDT and RFA. Pooled rates of survival, stent patency, 30-, 90-day mortality, and adverse events were calculated. Study heterogeneity was assessed using I2% and 95% prediction interval. RESULTS A total of 55 studies (2146 patients) were included. A total of 1149 patients underwent treatment with PDT (33 studies), 545 with RFA (22 studies), and 452 patients with stent-only strategy. The pooled survival rate with PDT, RFA, and stent-only groups was 11.9 [95% confidence interval (CI): 10.7-13.1] months, 8.1 (95% CI: 6.4-9.9) months, and 6.7 (95% CI: 4.9-8.4) months, respectively. The pooled time of stent patency with PDT, RFA, and stent-only groups was 6.1 (95% CI: 4.2-8) months, 5.5 (95% CI: 4.2-6.7) months, and 4.7 (95% CI: 2.6-6.7) months, respectively. The pooled rate of 30-day mortality with PDT was 3.3% (95% CI: 1.6%-6.7%), with RFA was 7% (95% CI: 4.1%-11.7%) and with stent-only was 4.9% (95% CI: 1.7%-13.1%). The pooled rate of 90-day mortality with PDT was 10.4% (95% CI: 5.4%-19.2%) and with RFA was 16.3% (95% CI: 8.7%-28.6%). CONCLUSION PDT seemed to demonstrate better overall survival and 30-day mortality rates than RFA and/or stent-only palliation.

Abstract
BACKGROUND Photodynamic therapy (PDT) is a therapy evaluated for the treatment of cancers resistant to standard oncological treatments. PDT might be beneficial for the palliation of hilar cholangiocarcinoma. AIM To evaluate the efficacy and safety of PDT for treating hilar cholangiocarcinoma. METHODS PubMed, Embase, the Cochrane Library, and Web of Science were searched for articles published up to May 2021. The patients were grouped as PDT+stent vs. stent alone. The outcomes were survival, quality of life, and adverse events (AEs). Data were summarized using hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs). RESULTS Six studies were included in this meta-analysis. There were 235 and 211 patients in the PDT+stent and stent groups, respectively. The 1-year survival rate of the PDT+stent group was 0.56, and that of the control group was 0.25. The 2-year survival rate of the PDT+stent group was 0.16, and that of the control group was 0.07. PDT significantly prolonged overall survival compared to the controls (P = 0.002). No differences were detected in the occurrence of cholangitis (P = 0.996) and all other AEs (early complications, stent malfunction, total AEs, acute pancreatitis, liver abscess, and biliary hemorrhage) between the two groups. CONCLUSION PDT in patients with hilar cholangiocarcinoma could improve survival without additional AEs. Large-scale randomized controlled trials are needed to confirm the findings.

Abstract
PURPOSE Patient-reported outcomes including health-related quality of life (HRQoL) are important oncological outcome measures. The validation of HRQoL instruments for patients with hepatocellular and cholangiocellular carcinoma is lacking. Furthermore, studies comparing different treatment options in respect to HRQoL are sparse. The objective of the systematic review and meta-analysis was, therefore, to identify all available HRQoL tools regarding primary liver cancer, to assess the methodological quality of these HRQoL instruments and to compare surgical, interventional and medical treatments with regard to HRQoL. METHODS A systematic literature search was conducted in MEDLINE, the Cochrane library, PsycINFO, CINAHL and EMBASE. The methodological quality of all identified HRQoL instruments was performed according to the COnsensus-based Standards for the selection of health status Measurements INstruments (COSMIN) standard. Consequently, the quality of reporting of HRQoL data was assessed. Finally, wherever possible HRQoL data were extracted and quantitative analyses were performed. RESULTS A total of 124 studies using 29 different HRQoL instruments were identified. After the methodological assessment, only 10 instruments fulfilled the psychometric criteria and could be included in subsequent analyses. However, quality of reporting of HRQoL data was insufficient, precluding meta-analyses for 9 instruments. CONCLUSION Using a standardized methodological assessment, specific HRQoL instruments are recommended for use in patients with hepatocellular and cholangiocellular carcinoma. HRQoL data of patients undergoing treatment of primary liver cancers are sparse and reporting falls short of published standards. Meaningful comparison of established treatment options with regard to HRQoL was impossible indicating the need for future research.

Photodynamic Therapy Using Hippo Pathway Inhibitor Verteporfin: A Potential Dual Mechanistic Approach in Treatment of Soft Tissue Sarcomas. Cancers (Basel) 2021; 13:cancers13040675. [PMID: 33567506 PMCID: PMC7915813 DOI: 10.3390/cancers13040675] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 02/02/2021] [Accepted: 02/05/2021] [Indexed: 12/30/2022] Open
Abstract
Simple Summary Advanced sarcomas have yet to undergo improved outcomes seen in other cancer subtypes. Verteporfin has the potential to show landmark change in sarcoma due to its anti-proliferative properties: inhibition of the Hippo pathway and as photodynamic therapy. The effect of verteporfin on the Hippo pathway is reviewed specifically in the setting of sarcoma due to increased activation of this pathway in multiple subtypes. Role and efficacy of photodynamic therapy in other malignancies is also reviewed, with additional discussion of preclinical studies demonstrating synergistic effects of photodynamic therapy within current sarcoma standard of care treatment. Future investigations of the feasibility of incorporating verteporfin into sarcoma treatment are discussed. Abstract Sarcoma is a widely varied and devastating oncological subtype, with overall five-year survival of 65% that drops to 16% with the presence of metastatic disease at diagnosis. Standard of care for localized sarcomas is predicated on local control with wide-local resection and radiation therapy, or, less commonly, chemotherapy, depending on tumor subtype. Verteporfin has the potential to be incorporated into this standard of care due to its unique molecular properties: inhibition of the upregulated Hippo pathway that frequently drives soft tissue sarcoma and photodynamic therapy-mediated necrosis due to oxidative damage. The initial anti-proliferative effect of verteporfin is mediated via binding and dissociation of YAP/TEAD proteins from the nucleus, ultimately leading to decreased cell proliferation as demonstrated in multiple in vitro studies. This effect has the potential to be compounded with use of photodynamic therapy to directly induce cellular necrosis with use of a clinical laser. Photodynamic therapy has been incorporated into multiple malignancies and has the potential to be incorporated into sarcoma treatment.

Abstract
Distal biliary strictures (DBS) are common and may be caused by both malignant and benign pathologies. While endoscopic procedures play a major role in their management, a comprehensive review of the subject is still lacking. Our consensus statements were formulated by a group of expert Asian pancreatico-biliary interventional endoscopists, following a proposal from the Digestive Endoscopy Society of Taiwan, the Thai Association for Gastrointestinal Endoscopy, and the Tokyo Conference of Asian Pancreato-biliary Interventional Endoscopy. Based on a literature review utilizing Medline, Cochrane library, and Embase databases, a total of 19 consensus statements on DBS were made on diagnosis, endoscopic drainage, benign biliary stricture, malignant biliary stricture, and management of recurrent biliary obstruction and other complications. Our consensus statements provide comprehensive guidance for the endoscopic management of DBS.

Abstract
Biliary obstruction is common in pancreatobiliary malignancies and has a negative impact on the patient’s quality of life, postoperative complications, and survival rates. Particularly in the last decade, there has been enormous progress regarding the diagnostic and therapeutic options in patients with malignant biliary obstruction. Endoscopy has given a new insight in this direction and novel techniques have been developed for the better characterization and treatment of malignant strictures. We herein summarize the available data on the different endoscopic techniques, and clarify their role in the diagnosis and treatment of malignant biliary obstructive disease. Finally, we propose an algorithm that can facilitate management decisions in these patients.

Abstract
There are several types of surgeries which use lasers in the operating room. Surgeons use lasers in general surgery or surgical specialties to cut, coagulate, and remove tissue. In modern medicine, the application of laser therapy is an attractive subject due to its minimal invasive effect. Today lasers are widely used in the treatment and diagnosis of many diseases such as various cancers, lithotripsy, ophthalmology, as well as dermatology and beauty procedures. Depending on the type of lasers, the wavelength and the delivery system, most lasers have replaced conventional surgical instruments for better wound healing results. Over time, by using many different tools and devices, new lasers have been created; as a result, they are used in a wide range of medical special cases. In this review, laser applications in surgery and its beneficial effects compared to previous surgeries with the aim of providing appropriate therapeutic and non-invasive solutions with minimal side effects after surgery are investigated.

Two cases of bile duct carcinoma patients who underwent the photodynamic therapy using talaporfin sodium (Laserphyrin ®). Clin J Gastroenterol 2019; 13:102-109. [PMID: 31222455 DOI: 10.1007/s12328-019-01006-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Accepted: 06/14/2019] [Indexed: 12/17/2022]
Abstract
The efficacy of adjuvant photodynamic therapy (PDT) using the new photosensitizer, talaporfin sodium (TPS) has been clinically examined in some patients with bile duct carcinoma (BDC). Based on our previous cohorts, a prospective clinical trial was attempted; however, only two cases were ultimately enrolled in 27 months. A 664-nm semiconductor laser (100 J/cm2) was applied through an endoscope to the tumor lesion within 6 h of an intravenous injection of 40 mg/m2 TPS according to the protocol for lung cancer. Case 1 was an 82-y.o. female patient with BDC at the left hepatic duct with biliary obstruction, percutaneous transhepatic biliary drainage (PTBD) was achieved, and the patient did not consent to surgery. She was followed up for 15 months to search for non-surgical treatments and eventually received PDT. Although mild photosensitivity occurred, she was discharged without severe adverse events. Biliary stenosis markedly extended and a PTBD tube was scheduled at 1 month. However, cancer immediately metastasized to the liver and she died 155 days after PDT. Case 2 was a 70-y.o. female with perihilar BDC and multiple biliary stenoses. Multiple biliary stenting was considered to be difficult. She received PDT and no adverse events were observed. Biliary stenoses markedly improved and multiple stenting was successfully performed. On day 132, she died of cancer progression. These two cases demonstrated the safety and efficacy of biliary malignant stenosis soon after PDT; however, long-term survival and a sufficient quality of life were not achieved. The combination of the PDT protocol and system chemotherapy or brachytherapy needs to be examined in clinical trials for advanced stage BDC.

Abstract
Background Endobiliary stenting is standard practice for palliation of obstructive jaundice due to biliary tract cancer (BTC). Photodynamic therapy (PDT) may also improve biliary drainage and previous small studies suggested survival benefit. Aims To assess the difference in outcome between patients with BTC undergoing palliative stenting plus PDT versus stenting alone. Methods 92 patients with confirmed locally advanced or metastatic BTC, ECOG performance status 0-3 and adequate biliary drainage were randomised (46 per group) to receive porfimer sodium PDT plus stenting or stenting alone. The primary end point was overall survival (OS). Toxicity and progression-free survival (PFS) were secondary end points. Treatment arms were well balanced for baseline factors and prior therapy. Results No significant differences in grade 3-4 toxicities and no grade 3-4 adverse events due to PDT were observed. Thirteen (28%) PDT patients and 24 (52%) stent alone patients received subsequent palliative chemotherapy. After a median follow-up of 8.4 months, OS and PFS were worse in patients receiving PDT compared with stent alone group (OS median 6.2 vs 9.8 months (HR 1.56, 95% CI 1.00 to 2.43, p=0.048) and PFS median 3.4 vs 4.3 months (HR 1.43, 95% CI: 0.93 to 2.18, p=0.10), respectively). Conclusion In patients with locally advanced or metastatic BTC, PDT was associated with worse outcome than stenting alone, explained only in part by the differences in chemotherapy treatments. We conclude that optimal stenting remains the treatment of choice for malignant biliary obstruction and the use of PDT for this indication cannot be recommended outside of clinical trials.

Abstract
Radiofrequency ablation (RFA) is a well-established treatment for several benign, premalignant, and malignant disorders. Although the role of RFA has been clearly defined, new indications for luminal and extraluminal applications of endoscopic RFA-directed therapies have emerged. RFA has recently produced promising results in patients with a variety of gastrointestinal and hepatopancreatobiliary pathologies. For example, endoscopic RFA has been used to treat patients with gastric antral vascular ectasia, chronic radiation proctitis, malignant biliary strictures, and ampullary adenomas with intraductal extension. Furthermore, endoscopic ultrasound-guided RFA appears to be an effective, minimally invasive treatment for ablation of solid and cystic lesions-particularly in the pancreas. We review the newer indications for RFA and discuss potential limitations of endoscopic RFA.

Abstract
The primary goal of nursing care in cases of endoscopic photodynamic therapy (PDT) for digestive tract carcinoma is to prevent phototoxicity by the intravenous administration of photosensitizers. The adequate protocol and management of patients should be conducted under the instruction of expert physicians. Our experiences of administering porfimer sodium and talaporfin sodium during clinical PDT provide insight regarding the specific management protocol of each photosensitizer during an in-hospital stay. We herein report our nursing protocol based on 15 years of experience. Under adequate management, PDT can be safely performed.

Abstract
Biliary tract cancer accounts for <1% of all cancers and affects chiefly an elderly population, with predominance in men. We distinguish cholangiocarcinoma (intrahepatic, hilar and distal) and gallbladder cancer, with different pathogenesis and prognosis. The treatment is based on surgery (whenever possible), radiotherapy in selected cases, and chemotherapy. The standard cytotoxic treatment for advanced/metastatic disease is represented by the combination of gemcitabine and cisplatin, whereas fluoropyrimidines are generally administered in second line setting. At the present time, no biologic drug demonstrated a clear efficacy in this cancer, although the molecular characterisation could provide a promising basis for experimental treatments. A good supportive care and an early palliative care are warranted in most patients and should be delivered as a part of a global approach.

Abstract
BACKGROUND The available evidence of Photodynamic therapy (PDT) combined with stent placement treatment for unresectable extrahepatic cholangiocarcinoma (EHCC) is still insufficient. It also remains unclear whether PDT influences systemic inflammatory response. AIM To explore the clinical efficacy and safety of the combination treatment and the systemic inflammatory response in patients with EHCC. METHODS Patients with unresectable EHCC underwent either the combined treatment using Hematoporphyrin PDT and stent placement (PDT+stent group, n=12) or stent-only (stent group, n=27). The primary end-point was overall survival. Tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels were measured. Quality of life was assessed using the Karnofsky performance scale (KPS) every 3 months. RESULTS Average survival time (13.8 vs. 9.6 months), and 6-month (91.7% vs. 74.1%), and 1-year (58.3% vs. 3.7%) survival rates of PDT+stent group were significantly increased compared with the stent group. KPS scores in the PDT+stent group were significantly improved. TNF-α and IL-6 levels were significantly increased in the PDT+stent group. CONCLUSION Hematoporphyrin-PDT combined with stent placement is an effective and safe treatment for EHCC. The treatment might promote systemic inflammatory response.

Abstract
BACKGROUND Photodynamic therapy (PDT) is a palliative treatment for malignant biliary obstruction. OBJECTIVE The objective of this article is to assess the feasibility and safety of this technique. METHODS In this nationwide, retrospective study of prospectively collected clinical data, all patients treated with PDT using polyhematoporphyrin in Austria from March 2004 to May 2013 were included. Feasibility, adverse events, stent patency and mortality rates were investigated. RESULTS Eighty-eight patients (54 male, 34 female, median age 69 years) underwent 150 PDT procedures at seven Austrian referral centers for biliary endoscopy. The predominant underlying disease was Klatskin tumor (79/88). All PDT procedures were feasible without technical issues. Cholangitis was the most frequent adverse event (21/88). Stent patency was 246 days (95% CI 203-289) median and was significantly longer for metal than for plastic stents (269 vs. 62 days, p < 0.01). The median survival was 12.4 months (95% CI 9.7-14.9 m) calculated from first PDT and 15.6 months (95% CI 12.3-18.7 m) calculated from initial diagnosis. In patients suffering from biliary tract cancer, Cox regression revealed the number of PDT treatment sessions as the only independent predictor of survival at a multivariate analysis (p = 0.048). CONCLUSION PDT using polyhematoporphyrin was feasible and safe in this nationwide analysis. Survival data suggest a benefit of PDT in this unselected real-life patient population. Prospective trials comparing PDT to other palliative treatments will help to define its role in the management of malignant biliary obstruction. The study is registered at ClinicalTrials.gov number: NCT02504957.

Abstract
BACKGROUND Photodynamic therapy with the placement of a biliary stent may improve the prognosis in patients with unresectable cholangiocarcinoma. The aim of this research is to determine the hazard ratio of photodynamic therapy with stent compared to biliary stenting alone or other therapies for the treatment of cholangiocarcinoma. METHODS Several databases were searched from inception to December 31 2013 for trials comparing photodynamic therapy+stent vs. stent-only or other treatments for cholangiocarcinoma. The outcomes of interest included patient survival, the changes of serum bilirubin levels, the quality of life (Karnofsky performance status), and adverse events. The hazard ratios (HR) were extracted from the survival curves using Tierney's Method. LnHR and its variance were pooled using an inverse variance-weighted average. Inconsistency was quantified using I(2) statistics. RESULTS In all, 8 trials comparing PDT+stent with other therapeutic methods were selected. We made a meta-analysis based on the 7 trials, which compared the result of PDT+stent and the stent-only group. HR summarizes the survival for the two groups. Overall survival was significantly better in patients who received photodynamic therapy than those who did not [HR=0.49, 95% confidence interval (CI), 0.33∼0.73, P=0.0005]. Among the 8 trials (642 subjects), 5 assessed the changes of serum bilirubin levels, and/or Karnofsky performance status, as other indications for improvement. In all, the incidence for phototoxic reaction is 11.11%. The incidence for other events in photodynamic therapy and the stent-only group was 13.64% and 12.79%, respectively. CONCLUSION The palliative treatment of cholangiocarcinoma, with photodynamic therapy, is associated with an increased survival benefit, an improved biliary drainage, and a better quality of life. However, the quality of this evidence is low.

Abstract
Hilar cholangiocarcinoma (CC) is non-resectable in the majority of patients often due to intrahepatic extension along bile duct branches/segments, and even after complete resection (R0) recurrence can be as high as 70%. Photodynamic therapy (PDT) is an established palliative local tumor ablative treatment for non-resectable hilar CC. We report the long-term outcome of curative resection (R0) performed after neoadjuvant PDT for downsizing of tumor margins in seven patients (median age 59 years) with initially non-resectable hilar CC. Photofrin(®) was injected intravenously 24-48 h before laser light irradiation of the tumor stenoses and the adjacent bile duct segments. Major resective surgery was done with curative intention six weeks after PDT. All seven patients had been curatively (R0) resected and there were no undue early or late complications for the neoadjuvant PDT and surgery. Six of seven patients died from tumor recurrence at a median of 3.2 years after resection, the five-year survival rate was 43%. These results are comparable with published data for patients resected R0 without pre-treatment, indicating that neoadjuvant PDT is feasible and could improve overall survival of patients considered non-curatively resectable because of initial tumor extension in bile duct branches/segments--however, this concept needs to be validated in a larger trial.

Temoporfin improves efficacy of photodynamic therapy in advanced biliary tract carcinoma: A multicenter prospective phase II study. Hepatology 2015; 62:1456-65.

Abstract
UNLABELLED Photodynamic therapy using porfimer (P-PDT) improves palliation and survival in nonresectable hilar bile duct cancer. Tumoricidal penetration depth of temoporfin-PDT (T-PDT) is twice that of P-PDT. In a single-arm phase II study we investigated the safety, efficacy, survival time, and adverse events of T-PDT compared with previous data on P-PDT. Twenty-nine patients (median 71 [range 47-88] years) with nonresectable hilar bile duct cancer were treated with T-PDT (median 1 [range 1-4] sessions) plus stenting and followed up every 3 months. The PDT was well tolerated. In patients with occluded segments at baseline (n=28) a reopening of a median of 3 (range 1-7) segments could be achieved: n=16 local response and n=11 stable local disease, one progressive disease. Cholestasis and performance significantly improved when impaired at baseline. Time to local tumor progression was a median of 6.5 (2.7-41.0) months. Overall survival time was a median of 15.4 (range 4.4-62.4) months. Patients died from tumor progression (55%), cholangitis (18%), pneumonia (7%), hemobilia (7%), esophagus variceal hemorrhage (3%), and vascular diseases (10%). Adverse events were cholangitis (n=4), liver abscess (n=2), cholecystitis (n=2), phototoxic skin (n=5), and injection site reactions (n=7). Compared to previous P-PDT, T-PDT shows prolonged time to local tumor progression (median 6.5 versus 4.3 months, P<0.01), fewer PDT treatments needed (median 1 versus 3, P<0.01), a higher 6-month survival rate (83% versus 70%, P<0.01), and a trend for longer overall median survival (15.4 versus 9.3 months, P=0.72) yet not significantly different. The risk of adverse events is not increased except for (avoidable) subcutaneous phototoxicity at the injection site. CONCLUSION Temoporfin-PDT can safely be delivered to hilar bile duct cancer patients and results in prolonged patency of hilar bile ducts, a trend for longer survival time, and similar palliation as with P-PDT.

Abstract
Cholangiocarcinoma comprises 3% of all gastrointestinal malignancies. Prognosis is poor as the disease is locally advanced at the time of its presentation. Biliary endoprosthesis are widely used for biliary decompression, however, they only provides temporary relief. Photodynamic therapy and Radiofrequency ablation are two innovative approaches performed endoscopically to locally destruct the malignant tissue. This chapter focuses on their application and appropriate use along with their benefits and complications.

Abstract
Photodynamic therapy (PDT) is an effective local treatment modality as a cancer-specific laser ablation in malignancy of some organs including digestive tracts or bile duct. In Japan, PDT has been applied at the early period after the first clinical induction in 1980’s. Although the useful efficacy was clarified, PDT has not been fully applied because of the phototoxicity of the porfimer sodium. The next generated talaporfin-sodium was used for PDT, in which phototoxicity was reduced and, however, the clinical efficacy for digestive tract malignancy has not yet been clarified. By proceeding the experimental and clinical trials, it is necessary to clarify the evidence of efficacy as a local powerful treatment with the conventional surgery, brachiotherapy and chemotherapy in the future step.

Abstract
Background/Aims Patients with cholangiocarcinoma usually present at an advanced stage, and more than 50% of cases are not resectable at the time of diagnosis. Recently, photodynamic therapy (PDT) has been proposed as a palliative and neoadjuvant modality. We evaluated whether combination of PDT and chemotherapy is more effective than PDT alone. Methods In total, 161 patients with cholangiocarcinoma diagnosed between February 1999 and September 2009 were evaluated. Sixteen patients were treated with PDT and chemotherapy (group A), and 58 were treated with PDT (group B). Results The median survival was 538 days (95% confidence interval [CI], 475.3 to 600.7) in group A and 334 days (95% CI, 252.5 to 415.5) in group B (p=0.05). Lymph node metastasis status, serum bilirubin of pretreatment, tumor node metastasis stage, treatment method (PDT with chemotherapy vs PDT alone), time to PDT and the number of PDT sessions were prognostic factors with statistical significance in the univariate analysis. A multivariate analysis showed that PDT with chemotherapy and more than two sessions of PDT were significant independent predictors of longer survival in advanced cholangiocarcinoma (hazard ratio [HR], 2.23; 95% CI, 1.18 to 4.20; p=0.013 vs HR, 1.79; 95% CI, 1.044 to 3.083; p=0.034). Conclusions PDT with chemotherapy results in longer survival than PDT alone.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) is a malignancy with a poor 5-year survival rate (5%-10%). ERCP-directed radiofrequency ablation (RFA) or photodynamic therapy (PDT) can be performed as palliative therapy for unresectable CCA. ERCP with PDT is associated with improved survival compared with stent placement alone. However, ERCP-directed RFA has not been directly compared with PDT in patients with CCA. OBJECTIVE To compare overall survival in patients with unresectable CCA who underwent palliative ERCP-directed RFA versus PDT. DESIGN Retrospective cohort study. SETTING Tertiary-care academic medical center. PATIENTS Forty-eight patients with unresectable CCA who underwent ERCP-directed ablative therapy for palliation of unresectable CCA. INTERVENTIONS ERCP-directed RFA or PDT. MAIN OUTCOME MEASUREMENTS Overall survival by Kaplan-Meier analysis after initial treatment with either RFA or PDT. RESULTS Patients who underwent RFA (n = 16) demonstrated an overall survival similar to that of those who underwent PDT (n = 32), with a median survival of 9.6 versus 7.5 months, respectively (P = .799). Patient age (P = .45), sex (P = .52), and lead time (P = .59) from presentation to initial RFA or PDT had no significant association with survival. The presence of distant metastasis was inversely associated with survival (hazard ratio 3.55; 95% confidence interval, 1.29-9.77; P = .014). Patients who underwent RFA (compared with PDT) had a lower mean number of plastic stents placed per month (0.45 vs 1.10, P = .001) but also had more episodes of stent occlusion (0.06 vs 0.02, P = .008) and cholangitis (0.13 vs 0.05, P = .008) per month. LIMITATIONS Retrospective, single-center design. CONCLUSIONS Survival after ERCP-directed RFA and PDT was not statistically different in patients with unresectable CCA. A randomized, controlled trial is warranted to validate these preliminary results.

Abstract
BACKGROUND Photodynamic therapy (PDT) is a promising treatment option for local control of remnant cancer after surgical resection or biliary stenosis by the unresectable tumor in patients with bile duct carcinomas (BDC). To achieve effective tumor necrosis, an appropriate approach to laser irradiation is necessary. METHODS The efficacy of endoscopy-guided PDT using porfimer (n=12) or talaporfin sodium (n=13) was investigated by evaluating the transhepatic biliary routes and endoscopic retrograde biliary (ERB) routes in 25 patients with BDC. RESULTS Diseases included perihilar intrahepatic cholangiocarcinoma (ICC) in four patients, extrahepatic BDCs in 19 and ampular carcinoma (AC) in two patients. Adjuvant PDT after surgical resection was performed in 18 patients, and PDT for tumor biliary stenosis was performed in seven. In patients undergoing surgical resections, the mean period between the operation and PDT was 87±42 days. In patients who underwent prior surgical resections, the transhepatic route was used in five (28%), the jejunal loop was used in 11 (61%), the T-tube route was used in one, and the endoscopic retrograde cholangiography (ERC) route via papilla Vater was used in one. In unresectable BDC, the ERC route was used in four patients (57%), and the transhepatic biliary route was used in three (43%). Endoscopic-guided PDT could not be performed in one patient because of a technical failure. Except for the complication of photosensitivity, endoscopy-related complications were not observed in any patients. Patients undergoing PDT with porfimer sodium had a significantly longer admission period compared to patients undergoing PDT with talaporfin sodium (36 vs. 5 days, respectively) (P<0.01). CONCLUSIONS PDT was safely and definitively performed using the endoscopy-guided approach via the transhepatic or ERC route. By considering the disadvantages of both routes, PDT must be adequately achieved for local control of BDC.

Abstract
Photodynamic therapy (PDT) is a new therapeutic approach for the palliative treatment of malignant bile duct obstruction. In this study, we designed photosensitizer-embedded self-expanding nonvascular metal stent (PDT-stent) which allows repeatable photodynamic treatment of cholangiocarcinoma without systemic injection of photosensitizer. Polymeric photosensitizer (pullulan acetate-conjugated pheophorbide A; PPA) was incorporated in self-expanding nonvascular metal stent. Residence of PPA in the stent was estimated in buffer solution and subcutaneous implantation on mouse. Photodynamic activity of PDT-stent was evaluated through laserexposure on stent-layered tumor cell lines, HCT-116 tumor-xenograft mouse models and endoscopic intervention of PDT-stent on bile duct of mini pigs. Photo-fluorescence imaging of the PDT-stent demonstrated homogeneous embedding of polymeric Pheo-A (PPA) on stent membrane. PDT-stent sustained its photodynamic activities at least for 2 month. And which implies repeatable endoscopic PDT is possible after stent emplacement. The PDT-stent after light exposure successfully generated cytotoxic singlet oxygen in the surrounding tissues, inducing apoptotic degradation of tumor cells and regression of xenograft tumors on mouse models. Endoscopic biliary in-stent photodynamic treatments on minipigs also suggested the potential efficacy of PDT-stent on cholangiocarcinoma. In vivo and in vitro studies revealed our PDT-stent, allows repeatable endoscopic biliary PDT, has the potential for the combination therapy (stent plus PDT) of cholangiocarcinoma.

Abstract
Cholangiocarcinoma is a challenge to manage; mortality rate is nearly as high as the incidence. Unless curative resection is performed, these tumours are rapidly fatal because they respond poorly to current therapies. Symptoms occur late in cholangiocarcinoma and curative resection can be performed in less than half of the patients. In non-resectable disease, endoprostheses insertion can relieve jaundice and improve quality of life, provided that tumour extension does not lead to diffuse intrahepatic stenoses of ductal system. However, tumour growth cannot be influenced and therefore, prognosis remains dismal. Despite the fact, that radiotherapy and chemotherapy could reduce tumour volume and growth, no survival advantage has yet been shown. Photodynamic therapy has been evaluated as an new additional, palliative option. A randomised trial comparing photodynamic therapy plus endoprostheses insertion versus endoprostheses insertion alone, indicates a considerably benefit on survival time, cholestasis and quality of life in large, advanced cholangiocarcinoma. Furthermore, few specific side effects occurred. Since photodynamic therapy is the first approach leading to an improvement of prognosis, it should be offered to patients with non-resectable cholangiocarcinoma.

Abstract
Cholangiocarcinomas are often locally advanced or have metastasized, and at the time of diagnosis individuals often have a poor prognosis. Endoscopic treatment options traditionally include biliary decompression via stenting to allow for systemic chemotherapy and radiotherapy, with self-expanding metal biliary stents being preferred. Recent developments in locoregional therapy delivered endoscopically, such as photodynamic therapy and radiofrequency abalation, have shown promising results in improving patient survival.

Abstract
Cholangiocellular carcinoma (CCC) is a very aggressive tumor, which remains highly resistant to current chemoradiation therapies. Death is usually caused by the tumor burden. However, biliary obstruction, which leads to cholangitis and liver failure, is also a cause of death. Therefore, relief of biliary obstruction is one of the key palliative treatment options for patients with hilar or distal CCC. Radiologic or endoscopic insertions of stents (plastic or self-expanding metal) are definite biliary drainage options. Whereas stents alone can help achieve relief of bile duct obstruction, endoscopic ablative interventions with photodynamic therapy or radiofrequency ablation are also useful in destroying intraluminal tumor. Destroying the tumor leads to an increase in the luminal diameter of the obstructed bile duct, allowing for placement of more or larger diameter stents, and thus improving bile flow. Besides decreasing morbidity associated with obstruction, ablative therapies such as photodynamic therapy have also been associated with improved survival in a sub-group of patients with CCC and should therefore be incorporated into the treatment algorithm of any center treating patients with CCC.

Photodynamic therapy provides local control of cholangiocarcinoma in patients awaiting liver transplantation. Am J Transplant 2014; 14:466-71. [PMID: 24373228 DOI: 10.1111/ajt.12597] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2013] [Revised: 10/21/2013] [Accepted: 11/14/2013] [Indexed: 01/25/2023]
Abstract
Many transplant centers use endoscopically directed brachytherapy to provide locoregional control in patients with otherwise incurable cholangiocarcinoma (CCA) who are awaiting liver transplantation (LT). The use of endoscopic retrograde cholangiopancreatography (ERCP)-directed photodynamic therapy (PDT) as an alternative to brachytherapy for providing locoregional control in this patient population has not been studied. The aim of this study was to report on our initial experience using ERCP-directed PDT to provide local control in patients with unresectable CCA who were awaiting LT. Patients with unresectable CCA who underwent protocol-driven neoadjuvant chemoradiation and ERCP-directed PDT with the intent of undergoing LT were reviewed. Four patients with confirmed or suspected CCA met the inclusion criteria for protocol LT. All four patients (100%) successfully underwent ERCP-directed PDT. All patients had chemoradiation dose delays, and two patients had recurrent cholangitis despite PDT. None of these patients had progressive locoregional disease or distant metastasis following PDT. All four patients (100%) underwent LT. Intention-to-treat disease-free survival was 75% at mean follow-up of 28.1 months. In summary, ERCP-directed PDT is a reasonably well tolerated and safe procedure that may have benefit by maintaining locoregional tumor control in patients with CCA who are awaiting LT.

Randomised phase II trial of photodynamic therapy plus oral fluoropyrimidine, S-1, versus photodynamic therapy alone for unresectable hilar cholangiocarcinoma. Eur J Cancer 2014; 50:1259-68. [PMID: 24485665 DOI: 10.1016/j.ejca.2014.01.008] [Citation(s) in RCA: 69] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2013] [Revised: 01/02/2014] [Accepted: 01/08/2014] [Indexed: 12/15/2022]
Abstract
BACKGROUND Hilar cholangiocarcinoma is an uncommon cancer and its overall incidence is increasing. Photodynamic therapy (PDT) has been proposed as palliative management for unresectable hilar cholangiocarcinoma (UHC). To date, little is known about the role of the addition of systemic chemotherapy to PDT for UHC. We performed a prospective, randomised, phase II trial to compare PDT plus S-1 and PDT alone for UHC. METHODS Patients with UHC were randomly assigned (in a 1:1 ratio) to PDT plus S-1 or PDT alone. The primary end-point was overall survival. The secondary end-points were progression-free survival, complications, re-intervention rate and quality of life. This trial is registered with clinicalTrials.gov, number NCT00869635. FINDINGS Between February 2009 and May 2012, we randomly assigned 21 patients to receive PDT plus S-1 and 22 to receive PDT alone. The UHC patients treated with PDT plus S-1 showed higher 1-year survival rate compared with the patients treated with PDT alone (76.2% versus 32%, P=0.003) and prolonged overall survival (median 17 months, 95% confidence interval [CI]: 12.6-21.4, versus 8 months, 95% CI: 6-10, P=0.005, hazard ratio [HR], 0.36; 95% CI: 0.17-0.75). Regarding the secondary end-points, PDT plus S-1 was associated with prolonged progression-free survival compared with PDT alone (median 10 months [95% CI: 4.1-16] versus 2 months [95% CI: 0.4-3.5], P=0.009 (HR for progression 0.39, 95% CI: 0.19-0.83). There were no differences in the number of PDT sessions, the frequency of cholangitis, overall adverse events or the quality of life in either group. INTERPRETATIONS PDT plus S-1 was well tolerated and was associated with a significant improvement of overall survival and progression-free survival compared with PDT alone in patients with UHC. These findings warrant further clinical investigation of PDT plus S-1 in patients with UHC.

Abstract
Hilar cholangiocarcinoma (HC) is a rare tumor that causes devastating disease. In the late stages, this carcinoma primarily invades the portal vein and metastasizes to the hepatic lobes; it is associated with a poor prognosis. HC is diagnosed by its clinical manifestation and results of imaging techniques such as ultrasound, computed tomography, magnetic resonance cholangiopancreatography, endoscopic retrograde cholangiography, and percutaneous transhepatic cholangiography. Preoperative hepatic bile drainage can improve symptoms associated with insufficient liver and kidney function, coagulopathy, and jaundice. Surgical margin-negative (R0) resection, including major liver resection, is the most effective and potentially curative treatment for HC. If the tumor is not resected, then liver transplantation with adjuvant management can improve survival. We conducted a systematic review of developments in imaging studies and major surgical hepatectomy for HC with positive outcomes regarding quality of life.

Abstract
Malignant biliary obstruction can arise from intrahepatic, extrahepatic, and hilar locations from either primary or metastatic disease. Biliary-enteric surgical bypass has been surpassed in the last 20 years by endoscopic balloon dilation and stenting. The goal of stenting for biliary decompression is to palliate obstructive symptoms; it has not been shown that survival is affected by stenting alone. Novel endoscopic therapies, including photodynamic therapy and radiofrequency ablation, have been evaluated and show promise. Both therapies seem to be safe and effective in the treatment of malignant bile duct strictures but are in need of prospective studies of longer duration.

Abstract
The most common form in bile duct cancers is a highly desmoplastic cancer with a growth pattern characterized by periductal extension and infiltration. The prognosis of bile duct cancers, especially hilar cholangiocarcinoma, is limited by tumor spread along the biliary tree leading to refractory obstructive cholestasis, cholangitis, and liver failure. Although biliary endoprosthesis improves occlusion rates and reduces the number of therapeutic interventions, median survival time is not ameliorated. Photodynamic therapy (PDT) is a local photochemical tumor treatment that consists of a photosensitizing agent in combination with laser irradiation of a distinct wavelength. Tumor ablation with PDT combined with biliary stenting reduces cholestasis and significantly improves median survival time in selected patients with bile duct cancers.

Abstract
BACKGROUND Photodynamic therapy (PDT) combined with stenting is an effective treatment modality for palliation of nonresectable cholangiocarcinoma (CC). A drawback of standard PDT using Photofrin(®) as photosensitizer is the long lasting skin photosensitivity of up to 3 months. The aim of this study was to show the outcome of PDT of CC, potential side effects and to determine the best drug light interval (DLI) using mTHPC (Foscan(®)) at a low dose. METHODS 13 patients with nonresectable CC were treated with stenting and PDT (3mg Foscan(®) per treatment, 0.032-0.063 mg/kg body weight, 652 nm, 50 J/cm). Fluorescence measurements were performed with a single bare fiber for 5/13 patients prior to PDT at the tumor site to determine the fluorescence contrast. For another 7/13 patients, long-term fluorescence-kinetics were measured on the oral mucosa to determine the time of maximal relative fluorescence intensity. RESULTS The results so far indicate a median survival time of 13 months. Side effects such as perforations or skin phototoxicity could not be observed. Foscan(®) fluorescence within the tumor site was clearly detectable but a significant fluorescence contrast of tumor to adjacent healthy tissue could not be found. The fluorescence kinetics measured in the oral mucosa showed a maximum at 3.85 days (median) after drug administration. CONCLUSION Combined stenting and PDT performed with a low Foscan(®) dose results in equal and potentially longer survival times compared to standard Photofrin(®) PDT, while lowering the risk of side effects strongly. Thus it may improve the quality of life.

Abstract
AIM: To evaluate the effect of photodynamic therapy (PDT) on metal stent patency in patients with unresectable hilar cholangiocarcinoma (CC).
METHODS: This was a retrospective analysis of patients with hilar CC referred to our institution from December, 1999 to January, 2011. Out of 232 patients, thirty-three patients with unresectable hilar CC were treated. Eighteen patients in the PDT group were treated with uncovered metal stents after one session of PDT. Fifteen patients in the control group were treated with metal stents alone. Porfimer sodium (2 mg/kg) was administered intravenously to PDT patients. Forty-eight hours later, PDT was administered using a diffusing fiber that was advanced across the tumor by either endoscopic retrograde cholangiopancreatography or percutaneous cholangiography. After performance of PDT, uncovered metal stents were inserted to ensure adequate decompression and bile drainage. Patient survival rates and cumulative stent patency were calculated using Kaplan-Meier analysis with the log-rank test.
RESULTS: The PDT and control patients were comparable with respect to age, gender, health status, pre-treatment bilirubin, and hilar CC stage. When compared to control, the PDT group was associated with significantly prolonged stent patency (median 244 ± 66 and 177 ± 45 d, respectively, P = 0.002) and longer patient survival (median 356 ± 213 and 230 ± 73 d, respectively, P = 0.006). Early complication rates were similar between the groups (PDT group 17%, control group 13%) and all patients were treated conservatively. Stent malfunctions occurred in 14 PDT patients (78%) and 12 control patients (80%). Of these 26 patients, twenty-two were treated endoscopically and four were treated with external drainage.
CONCLUSION: Metal stenting after one session of PDT may be safe with acceptable complication rates. The PDT group was associated with a significantly longer stent patency than the control group in patients with unresectable hilar CC.

Abstract
BACKGROUND In patients with unresectable cholangiocarcinoma, photodynamic therapy (PDT) with porfimer sodium promotes biliary drainage and may improve survival and quality of life. AIM To prospectively evaluate the safety and efficacy of PDT in patients with locally advanced biliary tract carcinoma. METHODS Eligible patients had unresectable, histologically confirmed disease, a Karnofsky performance status of ≥30% and life expectancy >12 weeks. Patients received 2mg/kg i.v. of porfimer sodium, followed by endobiliary laser activation and stent replacement 48 h later. Patients were assessed clinically and radiologically before treatment and on day 28, and followed up thereafter at three-monthly intervals until death. RESULTS 36 patients were entered over an 18 months period: 14 males, 22 females, with a median age of 65 (30-79)yr and performance status of 80 (50-100). PDT was technically successful in all cases and was generally well tolerated; there was no grade 4 toxicity and no treatment-associated mortality. The median survival was 12 (1-84) months. CONCLUSIONS Porfimer sodium PDT can be delivered safely to patients with biliary tract cancer and is suitable for testing in phase III studies (UKCRN ID 1218).

Abstract
Cholangiocarcinoma is the second most common primary hepatobiliary malignancy after hepatocellular carcinoma and remains among the most difficult management problems faced by surgeons. Curative surgery is achieved in only 25% to 30% of patients. Local tumor extent, such as portal vein invasion and hepatic lobar atrophy, does not preclude resection. Long-term survival has been seen only in patients who underwent extensive liver resections, suggesting that bile-duct excision alone is less effective. The majority of patients have unresectable disease, with 20% to 30% incidence of distant metastasis at presentation. Unresectable patients should be referred for nonsurgical biliary decompression, and in potential curative resection candidates the use of biliary stents should be reduced. Liver transplantation provides the option of wide resection margins, expanding the indication of surgical intervention for selected patients who otherwise are not surgical candidates due to lack of functional hepatic reserve.

Abstract
Perihilar cholangiocarcinoma (CCA) is the second most common primary malignant tumor of the liver. In the USA, there are approximately 3000 cases of CCA diagnosed annually, with approximately 50-70% of these tumors arising at the hilar plate of the biliary tree. Risk factors include advanced age, male gender, primary sclerosing cholangitis, choledochal cysts, cholelithiasis, parasitic infection, inflammatory bowel disease, cirrhosis and chronic pancreatitis. Patients typically present with jaundice, abdominal pain, pruritus and weight loss. The mainstays of treatment include surgery, chemotherapy, radiation therapy and photodynamic therapy. Specific preoperative interventions for patients with perihilar CCA include endoscopic retrograde cholangiopancreatography, percutanteous transhepatic cholangiography and portal vein embolization. Surgical resection offers the only chance for curative therapy in perihilar CCA. R0 resection is of utmost importance and has been linked to improved survival. Major hepatic resection is needed to achieve both longitudinal and radial margins negative for tumor. Fractionated stereotactic body radiotherapy has shown promising results in CCA. Perihilar CCA typically presents with advanced disease, and many patients receive systemic therapy; however, the response to current regimens is limited. Orthotopic liver transplantation offers complete resection of locally advanced tumors in select patient groups.

Abstract
BACKGROUND Photodynamic therapy (PDT) is an effective laser treatment for locally treating advanced bile duct carcinoma (BDC). The study objective was to evaluate the synergic effect of PDT using a new photosensitizer, talaporfin sodium (Laserphyrin), in combination with conventional anticancer drug treatments. METHODS The range of the necrotic area, the percentage of apoptosis-positive cells, the vascular endothelial growth factor expression quantification, and the proliferating cell nuclear antigen-labeling index, as treatment effects, were examined in the BDC cell line (NOZ) in vitro and in vivo (4-wk-old male BALB/c mice). RESULTS Tumor viability was determined by an in vitro MTS assay. PDT with a single treatment of 5-fluorouracil, gemcitabine, oxaliplatin, and cis-diamminedichloroplatinum showed a significantly lower viability compared with the control or the PDT-alone group (P<0.05). Furthermore, administering PDT combined with two anticancer drugs showed a further decline in the tumor viability. A treatment of PDT combined with oxaliplatin and gemcitabine showed the least viability (P<0.05). Thus, this regimen was administered in the in vivo study. The tumor necrotic area, apoptosis positivity, and the vascular endothelial growth factor expression rate were higher in the PDT with anticancer drugs group compared with those of the other groups (P<0.05). The proliferating cell nuclear antigen-labeling index results in the PDT with the anticancer drugs group were significantly lower than those of the other groups (P<0.05). CONCLUSIONS A treatment of PDT combined with gemcitabine and oxaliplatin showed the best synergic effect for necrosis, apoptosis, and cytostatic alterations for the treatment of BDC.

Abstract
BACKGROUND Photodynamic therapy (PDT) with placement of a biliary stent may improve bile duct patency in patients with cholangiocarcinoma (CCA). We aimed to determine the effectiveness of biliary stenting with PDT compared to biliary stenting alone in the palliative treatment of CCA. MATERIALS AND METHODS Several databases were searched from inception to December 2011 for prospective studies comparing biliary stenting with PDT vs. biliary stenting only for CCA. Outcomes of interest included patient survival, quality of life (using Karnofsky score), and serum bilirubin levels. The relative risk (RR) for dichotomous outcomes and the weighted mean difference (WMD) for continuous outcomes were estimated using DerSimonian and Laird random-effects model. Inconsistency was quantified using I(2) statistics. The extent of publication bias was ascertained by visual inspection of funnel plots and Egger's test. RESULTS There were six studies that met inclusion criteria. A total of 170 participants received PDT and 157 had biliary stenting only. Compared with biliary stenting, PDT was associated with a statistically significant increase in the length of survival (WMD 265 days; 95% CI: 154-376; p = 0.01; I(2) = 65%), improvement in Karnofsky scores (WMD 7.74; 95% CI: 3.73-11.76; p = 0.01; I(2)= 14%), and a trend for decline in serum bilirubin (WMD -2.92 mg/dL; 95% CI: -7.54 to 1.71; p=0.22; I(2) = 94%). The pooled event rate for biliary sepsis was 15% and was similar between PDT and control groups. CONCLUSION Palliative treatment of CCA with PDT is associated with increased survival benefit, improved biliary drainage, and quality of life. However, the quality of this evidence is low.

Abstract
OBJECTIVES This study aimed to determine longterm outcomes and factors associated with increased survival after photodynamic therapy (PDT) compared with endoscopic biliary drainage alone in patients presenting with advanced hilar cholangiocarcinoma (CC). METHODS A retrospective analysis of the institutional database identifying all patients who presented with a diagnosis of hilar CC between December 1999 and January 2011 was conducted. RESULTS Of the 232 patients identified, 72 (31%) were treated with PDT (Group A) and 71 (31%) were treated with endoscopic biliary drainage alone (Group B). Median survival was 9.8 months [95% confidence interval (CI) 7.42-12.25] in Group A and 7.3 months (95% CI 4.79-9.88) in Group B (P= 0.029). On multivariate analysis, biliary drainage without PDT (P= 0.025) and higher T-stage (P= 0.002) were significant predictors of shorter survival in all patients. In a subgroup analysis of patients in the PDT group, lower pre-PDT bilirubin level (P= 0.005), multiple PDT treatments (P= 0.044) and shortened time to treatment after diagnosis (P= 0.013) were significant predictors of improved survival. Median metal stent patency was longer in Group A than in Group B (215 days vs. 181 days; P= 0.018). CONCLUSIONS Photodynamic therapy with stenting resulted in longer survival than stenting alone. Early PDT after diagnosis and multiple PDT treatments were shown to have survival benefits. Metal stent patency was longer in patients receiving PDT. Higher T-stage appears to be a predictor of early mortality in advanced bile duct cancer treated with PDT.

Abstract
Cholangiocarcinoma (CC) is a rare primary malignancy of the biliary tract with a dismal prognosis. Curative resection can only be applied to a small proportion of early diagnosed patients. Palliative biliary drainage by either percutaneous or endoscopic insertion of endoprostheses improves quality-of-life by reducing pruritis, cholangitis, and pain, but has been reported to improve survival time only slightly. Photodynamic therapy (PDT) is a relatively new local, minimally invasive palliative strategy for unresectable CC. PDT uses a photosensitive molecule that accumulates in proliferating tissue such as tumors. Activation of the photosensitizer by use of light of a specific wavelength generates reactive oxygen species leading to selective tumor-cell death. After initial feasibility studies and promising prospective phase II studies, results from two prospective randomized controlled trials comparing PDT after endoprostheses insertion with endoprostheses alone for patients with unresectable CC have been published. One study resulted in dramatically prolonged median survival in the PDT group (493 days) compared with the non-PDT group (98 days) (P < 0.0001), and significantly improved performance status (PS) in the PDT group. A second study with high baseline patients' PS confirmed the benefit of PDT for survival (630 days in the PDT group compared with 210 days for endoprostheses alone, P < 0.01). The procedures were generally well tolerated. PDT has also been reported to have a favorable outcome as adjuvant and neoadjuvant therapy for CC. Although accumulated data and local expertise are limited, PDT can be regarded as a standard palliative therapy for unresectable CC.

Abstract
Background and Aim PDT is an important palliative option for patients with unresectable extrahepatic cholangiocarcinoma (CC). However, the results published to date reported on studies with no more than 6 (mostly up to 4) PDT procedures. Furthermore, the clinical experience of PDT in combination with chemotherapy is limited. The purpose of this retrospective analysis was to evaluate the feasibility and safety of multiple (4 to 14) settings of PDT, combined with biliary drainage, and (in some cases) with chemotherapy. Methods Ten patients with unresectable extrahepatic CC were treated with biliary stenting and at least 4 PDT procedures in our department between 10/2005 and 08/2010. Results Ten patients (male/female = 5/5), mean age 68.8 years (range, 54 - 81 years) who received at least 4 PDT procedures were analyzed. All patients underwent endoscopic biliary drainage. Nine patients received metallic stents and one patient a plastic stent. In 4 patients (40%) bilateral metal stenting (JoStent SelfX®) was performed. The mean number of PDT sessions was 7.9 ± 3.9 (range: 4 - 14). Eight patients had elevated bilirubin levels with a mean bilirubin at admission of 9.9 ± 11.3 mg/dL, which had decreased to an average minimum of 1.2 ± 0.9 mg/dL after 3 months. No severe toxicity was noted. Two patients received concomitant chemotherapy (GEMCIS as 1st line, GEMOX plus cetuximab as 2nd line). The median overall survival has not been reached, whereas the estimated survival of all patients was 47.6 months, 95% CI 25.9 - 48.1. Conclusion Long-term PDT in patients with extrahepatic CC is feasible and effective and is accompanied - at least in this cohort- by a survival time of more than 2 years.
