PURPOSE: To report a case of retinal detachment with a macular hole following photodynamic therapy (PDT) using verteporfin and intravtreal bevacizumab injection in the treatment of myopic choroidal neovasclarization (CNV). METHODS: A 58 -year-old woman was diagnosed with myopic CNV and treated with a combination of PDT with verteporfin and intravitreal bevacizumab injection that same day. She received the second injection of intravitreal bevacizumab four weeks after the initial treatment. RESULTS: The patient developed a sudden decline in vision one week after the second injection; and was subsequently diagnosed with retinal detachment associated with a macular hole. She underwent standard three-port pars plana vitrectomy with internal limiting membrane peeling, fluid-air exchange and silicone oil injection. The retina was still firmly attached at the patient's final follow-up visit. CONCLUSIONS: PDT and intravitreal bevacizumab injection used for the treatment of myopic CNV can be associated with retinal detachment with a macular hole. Patients need to be informed about this potential complication, and a higher index of suspicion may be warranted in patients who report sudden vision loss after the treatment.

OBJECTIVETo investigate the efficacy and safety of photodynamic therapy (PDT) with topical 5-aminolaevulinic acid (ALA) on cervical condylomata acuminata.

METHODSPatients with cervical condylomata (n=30) were allocated into primary and recurrent group, and were given topical ALA under occlusive dressing for 3 hours followed by irradiation with semiconductor laser at a dose of 100 Jcm(-2) and a power of 100 mW. The treatment was repeated 7 days later if the lesion was not completely removed after the first treatment. Complete response rate and recurrence rate of wart lesions as well as rate of adverse reaction were analyzed.

RESULTSThe total complete response rate of PDT was 100% and the total recurrence rate was 5% after 3 months of follow-up. Recurrence rate of recurrent group was significantly lower than that of prior managements (100%, P<0.01). The side effects of PDT in patients mainly included mild burning and/or stinging restricted to the illuminated areas, and was significant lower than their own control (25% vs. 100%, P<0.05).

CONCLUSIONCompared with conventional therapies, topical application of ALA-PDT is a simple, effective, safe, well-tolerated, and low recurrence rate treatment for cervical condylomata acuminata.

OBJECTIVEThis study investigated the hypothesis that 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) might alleviate acute graft-versus-host disease (GVHD) following allogenic bone marrow transplantation (allo-BMT) in mice.

METHODSAcute GVHD model following allo-BMT was established in 40 recipient BALB/C mice. Fifty C57BL/6J mice were used as donors and another 10 BALB/C mice as blank control without any intervention. Recipients received a lethal dose of 8.5 Gy (60)Co radiation for 10 minutes before transplantation and then were randomly divided into four groups of 10 mice (A-D). Group A was injected with normal saline injection and served as controls. Group B received pure donor bone marrow and spleen cell infusion. Group C received donor bone marrow and mixed donor-recipient spleen cell infusion. Group D was administered with an infusion of donor bone marrow cells and mixed donor-recipient spleen cells treated with ALA-PDT. The 28th day survival rate, incidence of acute GVHD and hematological and pathological changes after transplantation were examined.

RESULTSAll the mice from the Blank control group survived. The survival rates for Groups A-D on the 28th day were 0, 0, 10% and 60% respectively. Group D showed a significantly higher survival rate than the other three groups (P < 0.01). Most of the mice in Groups B and C developed GVHD but only two developed in Group D. Moreover Group D had less severe hematological and pathological changes when compared with Groups B and C.

CONCLUSIONSALA-PDT significantly alleviated GVHD and increased the 28th day survival rate for allo-BMT mice. ALA-PDT may be a promising therapy for GVHD following allo-BMT. Future studies should focus on the underlying mechanism of its therapeutic effect.

OBJECTIVETo use partial differential -aminolevulinic acid induced photodynamic therapy (ALA-PDT) increasingly in treating skin cancers and other diseases in many countries and to explore the efficacy of ALA-PDT for skin cancers in China.

METHODSEighty-eight patients, including 34 cases of basal cell carcinoma (BCC), 32 cases of squamous cell carcinoma (SCC), two cases of basal-squamous cell carcinoma (BSCC), one case of verrucuous carcinoma, nine cases of Bowen disease, two cases Paget disease of the nipple and eight cases of extramammary Paget disease, were treated by the partial differential alpha-aminolevulinic acid induced photodynamic therapy first in China from 1997 to 2000.

RESULTSAll BCC, including 11 cases of superficial lesions and 29 solid lesions, achieved complete reaction (CR) by 1-4 times of the ALA-PDT. Except one patient with adenoid SCC (grade III), all SCC (grade I and grade II) patients achieved complete remission by 3-6 times of ALA-PDT. All Bowen diseases achieved complete reaction by 1-4 times. Although for Paget diseases it could not cure the disease simply by ALA-PDT, it could control the symptoms. The recurrence rates were 11% (4/34) for BCC, and 22% (7/32) for SCC by following up 1-3 years after the therapy. The continuous therapy is still effective.

CONCLUSIONSALA-PDT is an effective, non-traumatic treatment for patients with BCC, SCC, Bowen and Paget diseases. It is especially suitable for older and weaker patients or those who are not tolerable to other therapies. It also has a unique advantage for tumors in specific anatomical areas. It is a new alternative modality for skin cancer therapies.

OBJECTIVE: To determine the effect of photodynamic therapy (PDT) for polypoidal choroidal vasculopathy (PCV). METHODS: Eleven patients (11 eyes) with PCV who were diagnosed by fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optic coherence tomography (OCT) were given PDT. The changes of best corrected visual acuity (BCVA), fundus photography, FFA and ICGA before and after the PDT were compared. Follow-up time varied from 6 to 30 months. RESULTS: One month after the PDT, the BCVA was stable in 3 eyes, increased in 1 line in 3 eyes, increased in 2 lines in 2 eyes, and decreased in 2 lines in 3 eyes. FFA and ICGA showed no leakage in 5 eyes, leakage reduced in 3 eyes, and slight leakage in 3 eyes. At the last follow-up, the BCVA was stable in 5 eyes, increased in 1 line in 2 eyes, increased in 2 lines in 2 eyes, and decreased in 2 lines in 2 eyes. FFA and ICGA showed no leakage in 6 eyes, leakage reduced in 3 eyes, and slight leakage in 2 eyes. No severe systemic or local adverse effect was found during or after the PDT, except that 1 eye had vitreous hemorrhage 2 months after the PDT. CONCLUSION PDT may stop or reduce leakage of the lesion, facilitate the absorption of hemorrhage, edema and exudates, and stabilize or increase the patients' visual acuity. It could be a choice for PCV.

PURPOSE: To evaluate the efficacy and safety of intravitreal bevacizumab for polypoidal choroidal vasculopathy (PCV). METHODS: In this retrospective interventional pilot study, 12 eyes of 11 patients with active PCV were treated with intravitreal bevacizumab (1.25 mg) alone or in combination with photodynamic therapy (PDT) depending on the informed patient's choice. Intravitreal bevacizumab was repeated at 6-week intervals until the regression of active lesion was detected on fluorescein angiography (FA) which was done on a regular basis, Indocyanine green angiography (ICGA) and optical coherence tomography (OCT) analyses. RESULTS: Intravitreal bevacizumab was given alone in 8 eyes (Group 1) and in combination with PDT in 4 eyes (Group 2). Mean follow-up duration was 17 weeks in group 1 and 15 weeks in group 2 after bevacizumab treatment. The mean number of bevacizumab injections was 2.2 in group 1 and 2.5 in group 2. Mean BCVA improved from 20/63 to 20/40 in group 1 and 20/63 to 20/32 in group 2. Of all eyes, the BCVA improved by > or =2 lines in seven (58%) eyes and resolution of fluid and hemorrhages in clinical examination, an absence of leakage on repeat FAs, or resolved pigment epithelial detachment (PED) and/or subretinal fluid (SRF) on OCT exam was confirmed in 10 (83%) eyes. Partial or complete regression of the polypoidal vessels and interconnecting vessels was reported for most cases at the last follow-up. No significant ocular or systemic side effects were observed in both groups. CONCLUSIONS: Short-term results indicate that intravitreal bevacizumab (1.25 mg) alone or in combination with PDT is well tolerated and associated with improvement in BCVA and reduced angiographic leakage in most patients. Further evaluation of intravitreal bevacizumab therapy for the treatment of PCV is warranted.

BACKGROUND/AIMS: The aim of this non-randomized study was to determine the role of photodynamic therapy (PDT) in a multimodal approach for the palliation of advanced esophageal carcinoma. METHODS: Twenty consecutive patients with obstructing esophageal cancer were enrolled in this study. Each subject had dysphagia, and nine could not swallow fluid. External beam radiotherapy or a self-expandable metal stent was used following PDT for dysphagia due to recurrence of the malignancy. RESULTS: At 4 weeks post-PDT, a significant improvement in the dysphagia score was observed in 90% of patients, from 2.75 +/- 0.91 to 1.05 +/- 0.83 (p < 0.05). Patients with recurrent dysphagia underwent stent insertion at an average of 63 days (range, 37 to 90). The rate of major complications was 10%. Two esophageal strictures occurred, which were treated by placement of a modified expandable stent across the stricture. The median survival in these cases was 7.0 +/- 0.6 months. One patient that was treated with PDT and radiotherapy is alive and showed a complete tumor response. CONCLUSIONS: PDT as a multimodality treatment is safe and effective for relieving malignant esophageal obstruction with minimal complications.
