Impact of Preoperative Intervertebral Disc Degeneration on Patient-Reported Outcome Measures After Lumbar Fusion.

OBJECTIVE: The Pfirrmann scoring system classifies lumbosacral disc degeneration based on MRI signal intensity. The relationship between pre-existing disc degeneration and PROMs after one-level lumbar fusion is not well documented. The purpose of this study was to investigate the relationship between the severity of preoperative intervertebral disc degeneration and pre- and postoperative patient-reported outcome measures (PROMs) in patients undergoing one-level lumbar fusion. METHODS: All adult patients underwent posterior lumbar decompression and fusion (PLDF) or transforaminal lumbar interbody fusion (TLIF) between 2014-2022 were included. Patient demographics, and comorbidities were extracted from medical records. Lumbar intervertebral discs on sagittal MRI T2-weighted images were assessed by two independent graders utilizing Pfirrmann criteria. Grades I-III were categorized as low-grade disc degeneration, while IV-V were considered high-grade. Multivariable linear regression assessed the impact of disc degeneration on PROMS. RESULTS: A total of 150 patients were included, of which, 69 (46%) had low grade disc degeneration, while 81 (54%) had high grade degeneration. Patients with high-grade degeneration had increased preoperative VAS-Leg scores (6.10 vs. 4.54, p=0.005) and displayed greater one-year postoperative improvements in VAS-Back scores (-2.11 vs -0.66, p=0.002). Multivariable regression demonstrated Pfirrmann scores as independent predictors for both preoperative VAS-Leg scores (p=0.004) and postoperative VAS-Back improvement (p=0.005). CONCLUSIONS: In patients undergoing one-level lumbar fusion, higher Pfirmann scores were associated with increased preoperative leg pain and greater one-year postoperative improvement in back pain. Further studies into the relationship of pre-operative disc degeneration and their impact on postoperative outcomes may help guide clinical decision making and patient expectations.

Topical 5-fluorouracil 1% for moderate to extensive ocular surface squamous neoplasia in 73 consecutive patients: Primary versus secondary treatment.

IMPORTANCE: Ocular surface squamous neoplasia (OSSN) is a spectrum of malignancies that generally includes conjunctival intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC). OSSN can be treated with topical therapies including interferon α-2b (IFN), mitomycin C (MMC), or 5-fluorouracil 1% (5FU). Recently, due to unavailability of IFN and toxicity associated with MMC, therapy has shifted towards 5FU. OBJECTIVE: Herein, we compare the use of 5FU 1% as a primary versus (vs) secondary treatment regimen in eyes with moderate to extensive OSSN. DESIGN SETTING AND PARTICIPANTS: Retrospective cohort study of 73 consecutive patients with unilateral moderate to extensive OSSN treated at a single tertiary ocular oncology center from 2016 to 2023. Mean follow up time was 478.2 days overall, with 283.0 days for primary 5FU group and 860.3 days for secondary 5FU group. INTERVENTION: Topical 5FU 1% 4 times daily for 2 weeks with option for 2-weekly extension until tumor control, either as primary treatment or as secondary treatment to surgical resection, topical IFN or topical MMC, or cryotherapy. MAIN OUTCOMES: Outcome measures included tumor response, need for additional surgery, complications, and visual outcomes. RESULTS: A comparison (primary vs secondary treatment) revealed no difference in mean tumor basal dimension (19.6 vs 17.2 mm, P = 0.46), thickness (3.7 vs 3.4 mm, P = 0.64), or tumor extent (4.4 vs 4.5 clock hours, P = 0.92). The primary treatment group showed greater complete tumor control (77% vs 38%, P = 0.04). Multivariable analysis comparison (primary vs secondary treatment) showed primary treatment more likely to achieve complete tumor control (P = 0.01). There was no difference in the complication rate from 5FU treatment between the groups. There was no difference in visual outcome, and no tumor-related metastasis (0%) or death (0%). CONCLUSION AND RELEVANCE: Topical 5FU 1% is efficacious and safe as a primary or secondary treatment for moderate to extensive OSSN. Tumors treated with primary 5FU 1% demonstrated more complete resolution. In patients with moderate to extensive OSSN, primary treatment with topical 5FU 1% may be warranted.

Clinical Outcomes of Faricimab in Patients with Previously Treated Neovascular Age-Related Macular Degeneration.

PURPOSE: To assess the anatomic and functional outcomes in eyes with neovascular age-related macular degeneration (nAMD) previously treated with anti-VEGF therapy in response to intravitreal faricimab. DESIGN: Retrospective, interventional, consecutive case series. SUBJECTS: Patients with previously treated nAMD who received ≥ 4 consecutive injections of faricimab were included. The study period was from March through November 2022. METHODS: Clinical and imaging data were extracted from the electronic medical record. Central foveal thickness (CFT), maximum fibrovascular pigment epithelial detachment (fvPED) height, and Snellen visual acuity (VA) were obtained. Generalized estimating equations were used to analyze the change in CFT, maximum fvPED height, and logarithm of the minimum angle of resolution VA. MAIN OUTCOME MEASURES: Change in CFT, maximum fvPED height, and Snellen VA before faricimab and after ≥ 4 faricimab intravitreal injections. RESULTS: During the study period, 218 eyes of 191 patients met inclusion criteria. Mean age was 79.9 (range, 70.6-89.2) years. The mean number of intravitreal anti-VEGF injections received before faricimab was 34.2 (range, 6.4-62). The following results were found after ≥ 4 faricimab injections. Mean logarithm of the minimum angle of resolution VA before switching to faricimab was 0.58 (Snellen VA ∼20/76; range, 20/22-20/264) and was 0.55 (Snellen VA ∼20/71; range, 20/21-20/235; P = 0.20) after switching. Mean maximum fvPED height was 195.0 (range, 50.2-339.8) µm before switching to faricimab and improved to 165.0 (range, 33.6-296.4; P < 0.001) µm after switching. Mean CFT was 354.8 (range, 184.7-524.9) µm before switching to faricimab and improved to 306.6 (range, 144.4-468.8; P < 0.001) after switching. The proportion of eyes with intraretinal fluid was 36.7% (80/218 eyes) before switching, and decreased to 24.8% (54/218 eyes, P < 0.001) after switching. The proportion of eyes with subretinal fluid was 53.2% (116/218 eyes) before switching and decreased to 26.6% (58/218 eyes, P < 0.001) after switching. CONCLUSIONS: Intravitreal faricimab may improve anatomic outcomes in patients with previously treated nAMD, while maintaining VA in the short-term.
