The clinical efficacy and safety of equipment-assisted intravesical instillation of mitomycin C after transurethral resection of bladder tumour in patients with nonmuscular invasive bladder cancer: A meta-analysis.
BACKGROUND
This review and meta-analysis aimed to systematically evaluate the clinical efficacy and safety of equipment-assisted intravesical instillation of mitomycin C (MMC) in patients with nonmuscular invasive bladder cancer (NMIBC) after transurethral resection of bladder tumour (TURBT).
METHODS
The Embase, PubMed, CNKI, CBM, WANGFANG, VIP, Cochrane Library, and Clinicaltrial.com databases were searched for articles published before April 2022. The experimental group was treated with intravesical instillation of MMC assisted by equipment, including radiofrequency-induced thermochemotherapy, conductive thermochemical therapy, electromotive drug administration, or locoregional hyperthermia. The control group was treated with simple MMC perfusion. The outcomes of interest in the meta-analysis were recurrence, progression, side-effects, gross haematuria, and bladder irritation.
RESULTS
A total of 15 studies that enrolled 1,190 patients were included in the meta-analysis. Compared to that of the control group, device-assisted intravesical instillation of MMC significantly reduced both tumour recurrence (odds ratio [OR] = 0.32, 95% confidence interval [CI] [0.24, 0.42], P <0.00001) and progression (OR = 0.29, 95% CI [0.12, 0.67], P = 0.004). There were no significant differences between the two groups in terms of safety (OR = 1.21, 95% CI [0.66,2.21], P = 0.54), bladder irritation (OR = 1.06, 95% CI [0.72,1.55], P = 0.78), or gross haematuria (OR = 1.11, 95% CI [0.64,1.94], P = 0.72).
CONCLUSIONS
Equipment-assisted intravesical instillation of MMC significantly reduced the recurrence and progression of patients with NMIBC who underwent TURBT and improved their quality of life. Given the significant heterogeneity in research quality and sample size among earlier studies, more prospective, multicentre, large sample randomized controlled trials are needed to supplement and verify this in the future.

Review
The aim of this study was to determine the prophylactic effect of intravesical chemotherapy. Furthermore, it aimed to compare the efficacy of regimens on the prevention of bladder recurrence, after nephroureterectomy, for upper tract urothelial carcinoma by systematic review and network meta-analysis. A comprehensive literature search was conducted to search for studies published before 22 December 2016 using PubMed, Embase, and Scopus. All studies comparing nephroureterectomy alone with prophylactic intravesical chemotherapy after nephroureterectomy were included. The primary outcome was intravesical recurrence-free survival rate. In addition, we conducted indirect comparisons among regimens using network meta-analysis, as well as three randomized controlled trials (RCTs) on multicenter setting, and one large retrospective study with a total of 532 patients were analyzed. The pooled hazard ratio (HR) of bladder recurrence was 0.54 (95% CI: 0.38-0.76) in intravesical instillation patients. On network meta-analysis, pirarubicin was ranked the most effective regimen, while maintenance therapy of mitomycin C (MMC) with Ara-C and induction therapy of MMC were ranked as the second and third most effective regimens, respectively. Our study demonstrates that intravesical chemotherapy can prevent bladder recurrence in patients with upper tract urothelial carcinoma after nephroureterectomy. It also suggests that a single instillation of pirarubicin is the most efficacious intravesical regimen.

Review
INTRODUCTION
Vascularized composite allotransplantation (VCA) is the transplantation of multiple tissue types as a solution for devastating injuries. Despite the highly encouraging functional outcomes of VCA, the consequences of long-term immunosuppression remain the main obstacle in its application. In this review, we provide researchers and surgeons with a summary of the latest advances in the field of cell-based therapies for VCA tolerance.
METHODS
Four electronic databases were searched: PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature , and Web of Science. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analysis as the basis of our organization.
RESULTS
Hematopoietic stem cells prolonged VCA survival. A combination of immature dendritic cells and tacrolimus was superior to tacrolimus alone. T cell Ig domain and mucin domain modified mature dendritic cells increased VCA tolerance. Bone marrow-derived mesenchymal stem cells prolonged survival of VCAs. A combination of adipose-derived mesenchymal stem cells, cytotoxic T-lymphocyte antigen 4 immunoglobulin, and antilymphocyte serum significantly improved VCA tolerance. Ex-vivo allotransplant perfusion with recipient's bone marrow-derived mesenchymal stem cells increased VCA survival. Recipient's adipose-derived mesenchymal stem cells and systemic immunosuppression prolonged VCA survival more than any of those agents alone. Additionally, a combination of peripheral blood mononuclear cells shortly incubated in mitomycin and cyclosporine significantly improved VCA survival. Finally, a combination of donor recipient chimeric cells, anti-αβ-T cell receptor (TCR), and cyclosporine significantly prolonged VCA tolerance.
CONCLUSIONS
Evidence from animal studies shows that cell-based therapies can prolong survival of VCAs. However, there remain many obstacles for these therapies, and they require rigorous clinical research given the rarity of the subjects and the complexity of the therapies. The major limitations of cell-based therapies include the need for conditioning with immunosuppressive drugs and radiation, causing significant toxicity. Safety concerns also persist as most research is on animal models. While completely replacing traditional immunosuppression with cell-based methods is unlikely soon, these therapies could reduce the need for high doses of immunosuppressants and improve VCA tolerance.

Meta-Analysis Review
Photorefractive keratectomy (PRK) is considered a safe approach laser procedure with a clinical significance in correcting myopia results. PRK requires removing the whole superficial epithelium. The integrity of the epithelial basement membrane and the deposition of abnormal extracellular matrix can put the cornea in a probable situation for corneal haze formation. Mitomycin C (MMC) is applied after excimer laser ablation as a primary modulator for wound healing, limiting corneal haze formation. We aim to summarize the outcomes of MMC application after laser ablation. We searched Scopus, PubMed, Cochrane CENTRAL, and Web of Science till December 2020 using relevant keywords. The data were extracted and pooled as mean difference (MD) or risk ratio (RR) with a 95% confidence interval (CI), using Review Manager software (version 5.4). Our analysis demonstrated a statistically significant result for MMC application over the control group in terms of corneal haze formation postoperatively (RR = 0.29, 95% CI: [0.19, 0.45], P < 0.00001). Regarding corrected distance visual acuity (CDVA), no significant difference was observed between the MMC group and the control group (MD = 0.02; 95% CI: [-0.04, 0.07]; P = 0.56). Regarding the uncorrected distance visual acuity (UDVA), the analysis favored the MMC application with (MD -0.03, 95% CI: [-0.06, -0.00]; P = 0.05). There was no statistically significant increase in complications with MMC. In conclusion, MMC application after PRK is associated with a lower incidence of corneal haze formation with no statistically significant side effects. The long term effect can show improvement regarding UDVA favoring MMC. However, there is no significant effect of MMCs application regarding CDVA, and SE.

BACKGROUND
Glaucoma is the leading cause of irreversible blindness. Minimally invasive surgical techniques, such as ab interno trabecular bypass surgery, have been introduced to prevent glaucoma from progressing. OBJECTIVES: In light of the potential benefits for people with open-angle glaucoma and the widespread uptake of the technique, it is important to critically evaluate the evidence for whether treatment with ab interno trabecular bypass surgery with Trabectome is both efficacious and safe.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL; which contains the Cochrane Eyes and Vision Trials Register; 2020, Issue 7); Ovid MEDLINE; Ovid Embase; the ISRCTN registry; ClinicalTrials.gov and the WHO ICTRP. The date of the search was 17 July 2020.
SELECTION CRITERIA
We searched for randomised controlled trials (RCTs) of ab interno trabecular bypass surgery with Trabectome compared to other surgical treatments (other minimally invasive glaucoma device techniques, trabeculectomy), laser treatment, or medical treatment. We also included trials in which these devices were combined with phacoemulsification compared to phacoemulsification in combination with other glaucoma surgery or alone.
DATA COLLECTION AND ANALYSIS
We used the standard methodological procedures expected by Cochrane. Our primary outcome was proportion of participants who were medication-free (not using eye drops). Secondary outcomes included mean change in intraocular pressure (IOP), proportion of participants who required further glaucoma surgery, mean change in quality of life, proportion of participants who achieved an IOP of 21 mmHg or less, 17 mmHg or less, or 14 mmHg or less and rate of visual field progression. Adverse effects were the proportion of participants experiencing intra- and postoperative complications. All outcomes were measured in the short term (6 to 18 months), medium term (18 to 36 months), and long term (36 months or longer).
MAIN RESULTS
In this update, we included one RCT which had previously been identified as an ongoing study in our 2016 publication. This trial was a single-centre, single-surgeon RCT set in Canada with 19 participants. Participants were adults who had open-angle glaucoma, open angles, and had inadequately controlled IOP that required surgical intervention. The study was terminated before the intended sample size was reached 'due to slow recruitment and increasing lack of clinical equipoise over time'. This reduced the power of the study to detect clinically important effects. We assessed the trial as being at high risk of attrition, reporting, and other potential sources of biases. The risks of performance and detection bias are unclear. The intervention group of 10 people had Trabectome ab interno trabeculotomy combined with cataract extraction (phaco-AIT) and the comparator group of 9 people had trabeculectomy with mitomycin C combined with cataract extraction (phaco-Trab), one of whom was lost to follow-up. Seven of 10 participants in the phaco-AIT group and 4 of 8 in the phaco-Trab group were medication-free (not using drops) at 12 months (odds ratio (OR) 2.33, 95% confidence interval (CI) 0.34 to 16.2; very low-certainty evidence). At 12 months, the mean change in IOP was worse for phaco-AIT than for phaco-Trab, but this evidence was very uncertain (mean difference (MD) 3.70 mmHg, 95% CI -1.44 to 8.84; very low-certainty evidence) in the phaco-AIT group, as was the difference in the mean number of IOP-lowering drops taken per day (MD -0.41, 95% CI -1.22 to 0.40; very low-certainty evidence). Only one participant in the phaco-AIT group required further glaucoma surgery. The study protocol declared that quality of life and visual field progression were measured, but they were not reported All 8 participants with complete data in the phaco-Trab group and 8 of 10 in the phaco-AIT had at least one early or late postoperative complication (e.g. day 1 IOP spike, hypotony, choroidal effusion, bleb leak or encapsulation, uveitis, or peripheral anterior synechiae). The evidence was very low-certainty due to high risk of bias for several domains for this study and for large imprecision of all estimates. We also identified one ongoing study, identified from the International Clinical Trials Registry Platform (ICTRP): a multicentre, open, RCT comparing Trabectome to ab interno trabeculectomy using microhook. The study investigators plan to recruit 120 adults between 20 and 90 years of age. The primary outcome is duration of treatment success. Secondary outcomes include postoperative IOP, number of anti-glaucoma medications, and adverse events.
AUTHORS' CONCLUSIONS
There is currently no high-quality evidence for the outcomes of ab interno trabecular bypass surgery with Trabectome for open-angle glaucoma. Properly designed RCTs are needed to assess the long-term efficacy and safety of this technique.

Meta-Analysis Review
BACKGROUND
Hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) following cytoreductive surgery (CRS) has been applied for peritoneal metastasis (PM) from colorectal cancer (CRC). This study aimed to compare oxaliplatin (OX) with mitomycin C (MMC) in HIPEC for PM from CRC in surgical and survival outcomes.
METHODS
A systematic literature search was performed in PubMed and Ovid databases for studies comparing OX with MMC in HIPEC for PM from CRC. The last search was performed on June 21, 2020.
RESULTS
Eleven articles published between 2006 and 2020 with 2091 patients were included. When compared with MMC group, the OX group showed significantly higher rate of major complications (P = 0.006, OR = 1.57, 95% CI [1.14, 2.16], I = 0%). Besides, no significant difference was observed between the two groups for survival outcomes, regardless of 3-year overall survival (P = 0.98, OR = 1.00, 95% CI [0.83, 1.22], I = 0%), 3-year disease-free survival (P = 0.98, OR = 1.00, 95% CI [0.83, 1.22], I = 0%), or 5-year overall survival (P = 0.91, OR = 1.01, 95% CI [0.81, 1.26], I = 0%).
CONCLUSION
OX and MMC could achieve comparable survival in HIPEC for PM from CRC. However, in consideration of the high incidence of major complication in OX group, MMC might be the safer one in clinical routines.

Review
BACKGROUND AND OBJECTIVE
Intravesical mitomycin C (MMC) instillations are recommended to prevent recurrence of intermediate-risk non-muscle-invasive bladder cancer (IR-NMIBC); however, the optimal regimen and dose are uncertain. Our aim was to assess the effectiveness of adjuvant MMC and compare different MMC regimens in preventing recurrence.
METHODS
We performed a comprehensive search in PubMed, Scopus, and Web of Science in November 2023 for studies investigating recurrence-free survival (RFS) among patients with IR-NMIBC who received adjuvant MMC. Prospective trials with different MMC regimens or other intravesical drugs as comparators were considered eligible.
KEY FINDINGS AND LIMITATIONS
Overall, 14 studies were eligible for systematic review and 11 for meta-analysis of RFS. Estimates of 1-yr, 2-yr, and 5-yr RFS rates were 84% (95% confidence interval [CI] 79-89%), 75% (95% CI 68-82%), and 51% (95% CI 40-63%) for patients treated with MMC induction plus maintenance, and 88% (95% CI 83-94%), 78% (95% CI 67-89%), and 66% (95% CI 57-75%) for patients treated with bacillus Calmette-Guérin (BCG) maintenance, respectively. Estimates of 2-yr RFS rates for MMC maintenance regimens were 76% (95% CI 69-84%) for 40 mg MMC (2 studies) and 66% (95% CI 60-72%) for 30 mg MMC (4 studies). Among the studies included, BCG maintenance provided comparable 2-yr RFS to 40 mg MMC with maintenance (78% vs 76%). RFS did not differ by MMC maintenance duration (>1 yr vs 1 yr vs <1 yr).
CONCLUSIONS AND CLINICAL IMPLICATIONS
MMC induction and maintenance regimens seem to provide short-term RFS rates equivalent to those for BCG maintenance in IR-NMIBC. For adjuvant induction and maintenance, 40 mg of MMC appears to be more effective in preventing recurrence than 30 mg. We did not observe an RFS benefit for longer maintenance regimens.
PATIENT SUMMARY
For patients with intermediate-risk non-muscle-invasive bladder cancer, bladder treatments with a solution of a drug called mitomycin C (MMC) seem to be as effective as BCG (bacillus Calmette-Guérin) in preventing recurrence after tumor removal. Further trials are needed for stronger evidence on the best MMC dose and treatment time.

Meta-Analysis
BACKGROUND
Epiphora is a common clinical sign whose primary cause is post-canalicular lacrimal obstruction. Treatment is both surgical and non-surgical. In the literature, there is some evidence to suggest that some treatments are superior to others, but there are no direct comparative data in this regard.
OBJECTIVE OF REVIEW
To analyse the success rates of all available treatments to resolve post-canalicular acquired lacrimal obstruction.
TYPE OF REVIEW
Systematic review and meta-analysis.
SEARCH STRATEGY
A literature search was conducted in the US National Library of Medicine (PubMed), EMBASE, SCOPUS and Cochrane databases with a final search performed in January 2020.
EVALUATION METHOD
The search strategy identified articles published later than 2000 with at least 50 procedures performed both surgically (external dacryocystorhinostomy [EXT-DCR], endoscopic dacryocystorhinostomy [END-DCR] and transcanalicular laser dacryocystorhinostomy [TCL-DCR]) and non-surgically (balloon dacryoplasty [DCP], probing-stenting [SP] and polyurethane stent [PoS]). The primary outcome was functional success, defined as symptom resolution or less than MUNK 2 scale; in addition to this, the influence of adjunctive treatments, such as application of mitomycin C and post-procedural silicone stenting, was evaluated.
RESULTS
In total, 14 958 papers were selected, 440 of which were reviewed after screening; 55 were included after full-text review, which involved 9337 procedures. Mean success rate was 48.9% (35.7%-62.3%) for DCP, 54.4% (41.8%-66.5%) for SP, 73.6% (59.7%-84%) for PoS, 80% (75.1%-84%) for TCL-DCR, 89.8% (83.3%-93.9%) for EXT-DCR and 89.5% (87.2%-91.5%) for END-DCR. Among all procedures, a difference was noted between DCP and END-DCR (P < .001), DCP and EXT-DCR (P < .001), SP and END-DCR (P < .001), SP and EXT-DCR (P < .001), END-DCR and PoS (P = .016), and END-DCR and TCL-DCR (P = .001); no differences were noted between END-DCR and EXT-DCR (P = 1.00), EXT-DCR and PoS (P = .121) and EXT-DCR and TCL-DCR (P = .223). Considering surgical procedures, no differences were seen if a silicone stenting was applied, whereas, due to heterogeneity of the literature data, no statistical analysis was feasible for application of mitomycin C.
CONCLUSIONS
Our analyses suggest that, among all procedures available, END-DCR and EXT-DCR should be considered as treatments of choice to resolve distal acquired lacrimal obstruction.

BACKGROUND
Induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) for non-metastatic locoregionally advanced nasopharyngeal carcinoma (NPC) has gained considerable attention. However, the most efficacious IC regimens remain investigational. We aimed to compare the survival benefits of all available IC regimens followed by CCRT in this network meta-analysis.
METHODS
All randomized-controlled trials of CCRT with or without IC in non-metastatic locoregionally advanced NPC were included, with an overall nine trials of 2,705 patients counted in the analysis. CCRT alone was the reference category. Eight IC regimens followed by CCRT were analyzed: docetaxel + cisplatin (DC), gemcitabine + carboplatin + paclitaxel (GCP), gemcitabine + cisplatin (GP), mitomycin + epirubicin + cisplatin + fluorouracil + leucovorin (MEPFL), cisplatin + epirubicin + paclitaxel (PET), cisplatin + fluorouracil (PF), cisplatin + capecitabine (PX) and cisplatin + fluorouracil (PF), cisplatin + capecitabine (PX). Fixed-effects frequentist network meta-analysis models was applied and P-score was used to rank the treatments.
RESULTS
DC, GP, and PX were the top three IC regimens with the highest probability of benefit on overall survival (OS). Their corresponding hazard ratios (HRs) (95% CIs) compared with CCRT alone were of 0.24 (0.08-0.73), 0.43 (0.24-0.77), and 0.54 (0.27-1.09) and the respective P-scores were 94%, 82%, and 68%. The first three IC regimens showing significantly improved progression-free survival (PFS) were PX, followed by GP and DC with respective HRs of 0.46 (0.24-0.88), 0.51 (0.34-0.77), and 0.49 (0.20-1.20), and P-scores of 82%, 78%, and 74%. Among the studies in the intensity-modulated radiation therapy (IMRT) era, GP and PX were the best performed IC regimens, whilst DC performed the best among non-IMRT studies. Doublet and gemcitabine-based IC regimens had better survival benefits compared to triplet and taxane-based IC regimens, respectively.
CONCLUSIONS
Given its consistent superiority in both OS and PFS, DC, GP, and PX ranked among the three most efficacious IC regimens in both the overall and subgroup analysis of IMRT or non-IMRT studies. Exploratory analyses suggested that doublet and gemcitabine-based IC regimens showed better survival performance.

OBJECTIVE
Many studies have evaluated the effectiveness of topical intraoperative mitomycin (MCC) usage in a wide range of otolaryngologic procedures with variable conclusions on effectiveness. This systematic review aims to provide a qualitative estimation of mitomycin C's treatment effectiveness in maintaining or preventing stenosis after surgical interventions.
DESIGN AND SETTING
Following the PRISMA guideline, a comprehensive systematic search of MEDLINE, EMBASE and CINAHL databases was performed including hand-searching and cross-reference checking.
PARTICIPANTS
The search was limited to humans, sample size greater than two and study designs including a comparative arm.
MAIN OUTCOME MEASURES
Outcome measures varied but included rates of restenosis, number of procedures, and post-surgical patency.
RESULTS
A total of 571 unique abstracts and 109 full articles were reviewed. Seventy-seven studies were included in the final analysis. The available evidence ranged from case series to randomized control studies. Meta-analysis was deemed inappropriate due to heterogeneity of study design. Thirty-eight studies assessed the effective of MCC in dacryocystorhinostomy, which is reported in a separate meta-analysis. All other studies were categorized into otolaryngologic site and pathology including choanal atresia (n = 5), endoscopic sinus surgery (n = 12), airway procedures (n = 9), esophageal procedures (n = 8) and other (n = 2).
CONCLUSIONS
The published literature on the effectiveness of MMC was mixed, but suggested topical MMC improved surgical outcomes in many otolaryngologic procedures compared to controls. This was the first review to assemble literature on MMC usage for different surgical procedures. Comprehensive interpretation of the data was limited due to heterogeneity in primary outcome, procedure type and study quality. High-quality prospective and randomized controlled studies are required to further confirm the positive effect of MMC use on surgical outcomes.
