Objective:To investigate the clinical efficacy and safety of different combination therapies with aminolevulinic acid photodynamic therapy (ALA-PDT) in the treatment of facial basal cell carcinoma in the elderly.Methods:A retrospective analysis was conducted on 131 elderly patients with facial basal cell carcinoma who visited Shanghai Skin Disease Hospital from August 2020 to October 2023. According to the depth of the lesions, the patients were divided into 3 groups to receive intensive pretreatment with curettage (41 cases), CO 2 laser therapy (35 cases), and narrow-margin excision surgery without sutures (55 cases) respectively, all followed by ALA-PDT. During the follow-up period of 17.7 ± 9.0 months, the efficacy was evaluated and adverse reactions were recorded in each group. Results:The total remission rates were 100%, 100%, and 96.4% in the curettage + ALA-PDT group, CO 2 laser + ALA-PDT group, and narrow-margin excision surgery without sutures + ALA-PDT group, respectively. The patients experienced mild pain and local erythematous swelling during ALA-PDT treatment, which were temporary and fully tolerable, and no wound infections or difficulties in healing were observed. After treatment, scar formation was observed in 3 cases of basal cell carcinoma on the nose and nasolabial folds in the narrow-margin excision surgery without sutures + ALA-PDT group, but the rest of the patients retained a good facial appearance. Conclusions:In this preliminary exploration study on PDT for basal cell carcinoma of different depths, ALA-PDT combined with curettage, CO 2 laser or narrow-margin excision surgery without sutures all exhibited definite efficacy and minimal damage, providing effective treatment options for facial basal cell carcinoma in the elderly.

Objective:To explore the application of 16-words formula " resection surrounding the proximal part of seminal colliculus, lateral tunnel, plane extending and bladder neck preservation" in transurethral enucleation resection of prostate with plasma rod electrode (TUERP).Methods:The clinical data of 88 patients with benign prostatic hyperplasia (BPH) admitted to our department from May 2018 to July 2019 were retrospectively analyzed. The age of patients was (67.0±8.6)years, and the volume of prostate was (51.0±27.3)ml. All patients were treated with TUERP using transurethral plasma rod electrodes according to the above 16-words formula. The perioperative clinical data and follow-up results at the 3rd month postoperation were statistically analyzed.Results:All operations were successfully completed. The operation time was (49.7±17.7)min, including gland enucleation time (16.8±6.7)min, tissue resection time (33.0±12.3)min, enucleated tissue weight (45.5±24.4)g, intraoperative blood loss (10.2±2.9)ml, postoperative continuous bladder irrigation time (1.9±0.8)d, postoperative hospital stay (4.1±0.7)d. There were no significant changes in hemoglobin and sodium concentration at 2 hours after operation ( P>0.05). The International Prostate Symptom Score (IPSS), quality of life score (QOL), maximum urinary flow rate (MFR) and residual bladder urine were significantly improved at 3 months after operation ( P<0.05). The patients were followed up for 3 to 14 months (average 6.8 months). There were 6 cases of Clavien grade Ⅰ complications, 1 case of Clavien Ⅱ complications, 1 case of Clavien Ⅲ complications, and no Clavien Ⅳ-Ⅴ complications occurred. Conclusions:The TUERP with plasma rod electrode according to the 16-words formula is an ideal choice for BPH treatment, which has the advantages of simple operating, high efficiency of enucleation, less blood loss, fast recovery and satisfied improvement of urination symptom.
