OBJECTIVE: Meningiomas are one of the most frequently occurring brain tumors and can be curatively treated with gross-total resection. A subtotal resection increases the chances of recurrence. The intraoperative identification of invisible tumor remnants by using a fluorescent tracer targeting an upregulated biomarker could help to optimize meningioma resection. This is called molecular fluorescence-guided surgery (MFGS). Vascular endothelial growth factor α (VEGFα) has been identified as a suitable meningioma biomarker and can be targeted with bevacizumab-IRDye800CW.
METHODS: The aim of this prospective phase I trial was to determine the safety and feasibility of bevacizumab-IRDye800CW for MFGS for intracranial meningiomas by administering 4.5, 10, or 25 mg of the tracer 2-4 days prior to surgery. Fluorescence was verified during the operation with the standard neurosurgical microscope, and tissue specimens were postoperatively analyzed with fluorescence imaging systems (Pearl and Odyssey CLx) and spectroscopy to determine the optimal dose. Uptake was compared in several tissue types and correlated with VEGFα expression.
RESULTS: No adverse events related to the use of bevacizumab-IRDye800CW occurred. After two interim analyses, 10 mg was the optimal dose based on ex vivo tumor-to-background ratio. Although the standard intraoperative imaging revealed no fluorescence, postoperative analyses with tailored imaging systems showed high fluorescence uptake in tumor compared with unaffected dura mater and brain. Additionally, tumor invasion of the dura mater (dural tail) and invasion of bone could be distinguished using fluorescence imaging. Fluorescence intensity showed a good correlation with VEGFα expression.
CONCLUSIONS: Bevacizumab-IRDye800CW can be safely used in patients with meningioma; 10 mg bevacizumab-IRDye800CW provided an adequate tumor-to-background ratio. Adjustments of the currently available neurosurgical microscopes are needed to achieve visualization of targeted IRDye800CW intraoperatively. A phase II/III trial is needed to methodically investigate the benefit of MFGS with bevacizumab-IRDye800CW for meningioma surgery in a larger cohort of patients.

BACKGROUND: Breast cancer stands as a leading contributor to global cancer-related mortality. Progressing Research and Medical Innovations Elevate Treatment Choices and Results for Breast Cancer. Among these, Peimine, a natural steroid inherent in plants, notably within the Fritillaria species, demonstrates the capability to trigger apoptosis in breast cancer cells through the mitochondrial membrane permeation pathway. Nevertheless, its impact on an appropriate cancer model remains an area necessitating further exploration.
OBJECTIVE: This study explored the in vivo anticancer effects of peimine on MRMT-1 Cell-line induced breast cancer in rats.
METHODS: Cancer was induced by the administration of MRMT-1 (6 x 106 cells) cells in the mammary pads of SD rats. The daily drug treatmentcommenced on day 14 and continued till 39 days. Peimine was administered in two doses (0.24 mg/kg and 0.48 mg/kg p.o) to examine its efficacy in curing breast cancer while tamoxifen was used as standard.
RESULTS: A reduction in tumour size was observed in the peimine-treated groups. Peimine can correct the changed blood cell count in addition to its anti-tumour activity. In peimine-treated rats, imbalanced immune marker IgE, serum oxidative marker, and tissue apoptotic markers like cytochrome c and calcium level were shown to be restored significantly.
CONCLUSIONS: Our findings imply that quinine has beneficial effects as an anti-neoplastic medication for breast cancer, most likely through its apoptotic activity. More research is necessary to thoroughly understand their mechanisms of action, ideal dose, and potential side effects.

OBJECTIVE: The objective of this study was to develop a nomogram to predict long-term facial nerve (FN) function after vestibular schwannoma (VS) resection.
METHODS: A retrospective cohort study of two tertiary academic skull base referral centers was performed. Consecutive adults > 18 years of age with sporadic unilateral VS who underwent resection between September 2016 and May 2021 were included. FN function in the immediate postoperative period and at the most recent evaluation was measured.
RESULTS: A total of 306 patients (mean age 49 years, 63% female) were included, with a mean follow-up of 18 months. The mean maximum tumor diameter was 19 mm (range 1-50 mm), and 80 (26.1%) tumors were > 25 mm. Overall, 85% of patients showed good immediate postoperative FN function (House-Brackmann [HB] grade I or II) and 89% maintained good FN function at > 12 months of follow-up. An intraoperative FN electromyographic (EMG) response ≥ 100 µV to 0.05 mA of stimulation (OR 18.6, p < 0.001) was the strongest predictor of good HB grade in the immediate postoperative period. EMG response ≥ 100 µV (OR 5.70, p < 0.001), tumor size ≤ 25 mm (OR 3.09, p < 0.05), and better immediate postoperative HB grade (OR 1.48, p = 0.005) predicted good long-term FN function on multivariable analysis. A point-of-care nomogram based on these data predicted long-term FN function with a sensitivity of 89% and specificity of 69%.
CONCLUSIONS: Better immediate postoperative HB grade, intraoperative FN EMG response ≥ 100 µV, and tumor size ≤ 25 mm strongly predicted good long-term FN function after VS resection. A point-of-care nomogram based on these variables could serve as a useful tool for postoperative counseling and prognosis of long-term FN recovery.

OBJECTIVE: To study the efficacy and side-effect profile of topical 5-Fluorouracil (5-FU) in the treatment of ocular surface squamous neoplasia (OSSN).
METHODS: Retrospective study of 101 eyes of 100 patients treated with 5-FU with one week on and 3 weeks off regimen.
RESULTS: Of the 100 patients (101 eyes), the mean age at diagnosis of OSSN was 49 (median, 52 years; range, 11-87 years). History of prior intervention was noted in 6 (6%) eyes. Tumor epicenter included bulbar conjunctiva (n = 54; 53%), limbus (n = 27; 27%), and cornea (n = 20;20%). Mean number of cycles of topical 5-FU administered was 3 (median, 3; range, 1-8). Complete tumor regression was achieved with topical 5-FU in 89 (88%) eyes with a mean number of 2 cycles (median, 2; range, 1-6) of 5-FU. The remaining 12 (12%) lesions underwent additional treatment including excisional biopsy (n = 7), extended enucleation (n = 3), and topical Interferon alpha 2b (n = 2) for complete tumor control. Over a mean follow-up period of 6 months (median, 5 months; range, 1-36 months) following treatment, tumor recurrence was noted in 2 (2%) patients, and side-effects were noted in 7 (7%) eyes including conjunctival hyperemia (n = 1), punctal stenosis (n = 1), sterile keratitis (n = 4), and limbal stem cell deficiency (n = 1).
CONCLUSIONS: Topical 5-FU is an effective non-invasive therapy for OSSN with a minimal side-effect profile.

METHODS: Retrospective Cohort Study.
OBJECTIVE: Scoring systems for metastatic disease of the spine are used to select patients for surgical treatment based on survival estimation, but it is unknown whether they can be used to predict the outcome of surgery. This study aims to investigate the association between two widely used prognostic scores and the neurologic function after surgery.
METHODS: Retrospective analysis of 204 patients with thoracolumbar metastases treated with decompressive surgery at Karolinska University Hospital (2001-2020). Modified Bauer and Tokuhashi scores were categorized based on surgical indication, and post-operative neurological function was assessed using the Frankel scale at two different post-surgery intervals.
RESULTS: Modified Bauer scores ≥2 yielded higher late follow-up Frankel scores (3.9 ± 1.1) than scores <2 (3.5 ± 1.1), P = .03. Modified Tokuhashi scores ≥9 correlated with higher Frankel scores (4.5 ± .9) than scores <9 (3.5 ± 1.1), P < .0001. Both scoring systems positively predicted neurological outcomes at late follow-up, with odds ratios of 1.6 (P = .03) for Bauer and 9.2 (P < .0001) for Tokuhashi. However, only Tokuhashi predicted ambulatory function at late follow-up (P < .0001), demonstrating its utility in prognosticating post-surgical mobility.
CONCLUSIONS: Higher modified Bauer and Tokuhashi scores were associated with better neurologic function at last follow-up, as well as greater likelihood of being able to walk again. The Tokuhashi score was found to be more accurate than the modified Bauer score in predicting the neurological outcome after surgery.

UNASSIGNED: Brain tumors are common, requiring physicians to have a precise understanding of them for accurate diagnosis and treatment. Considering that various histological tumor types present different cellularity, we conducted this research to examine the role of apparent diffusion coefficient (ADC) values in the differential diagnosis and pathologic grading of brain tumor types.
UNASSIGNED: In this cross-sectional study, we gathered pathology reports of histological samples of adult brain tumors. The tissue sample of brain tumors were examined histologically by a pathologist. The magnetic resonance imaging data of these patients were interpreted by a neuroradiologist. The measured ADC values and ADC ratios were calculated. Standard mean ADC values were expressed as 10- 6 mm2/s. The findings were compared according to the histological diagnosis of each tumor.
UNASSIGNED: Sixty-eight patients were included in the study: 34 (50%) were male, and 34 (50%) were female. The average age of the patients was 51.69 + 16.40 years. In the examination of tumor type, 16 (23.5%) were astrocytoma, 9 (13.2%) were oligodendroglioma, 20 (29.4%) were glioblastoma, 4 (5.9%) were medulloblastoma, and 19 (27.9%) were metastatic tumors. the average value of ADC was statistically significantly different according to the pathological type of tumor (p < 0.001). The two-by-two comparison of average ADC among tumor types revealed significant differences, except for oligodendroglioma and glioblastoma (p-value = 0.87) and glioblastoma and medulloblastoma (p-value = 0.347). The average value of ADC and ADC ratio was statistically significantly different according to the pathological grade of the tumor (p < 0.001). In the two-by-two comparison of average ADC between all pathological grades of the tumor showed a significance difference except for Grade I and Grade II (p-value = 0.355). The mean value of ADC and ADC ratio for glioblastoma and metastatic tumors showed no significant difference.
UNASSIGNED: The assessment of brain tumor grade through ADC examination will help to estimate prognosis and devising suitable therapeutic strategies.

UNASSIGNED: Comorbidities in patients with cancer can affect treatment, and should, therefore, be prioritized and managed.
UNASSIGNED: Our primary aim was to assess the prevalence of comorbidities among patients with cancer. The secondary objective was to identify the association of comorbidities with various sociodemographic and clinical variables.
UNASSIGNED: This was a cross-sectional study conducted between December 2019 and March 2020 among patients with cancer, seeking treatment at Malabar Cancer Center, in Kannur District of northern Kerala in South India. Semi-structured interviews were conducted, and comorbidities were assessed using the Charlson Comorbidity Index. The anthropometric measurements were recorded using a standardized instrument and protocol.
UNASSIGNED: We enrolled 242 patients in this study. There were 148 (61.2%) female patients; 106 (43.8%) were aged between 41 and 50 years. Cancers of the head-and-neck and breast accounted for the majority of cases (23.1% each, n = 56), followed by the digestive system (18.6%, n = 45) and female reproductive system (11.2%, n = 27). The most common primary cancers in the head-and-neck, digestive, and female reproductive systems were oral, colorectal, and cervical, respectively. The prevalence of comorbidities among patients with cancer was 70.2% (n = 170). Common comorbidities were hypertension (n = 82 ; 33.9%), arthritis (n = 57; 23.6%), and diabetes (n = 53; 21.6%). After controlling for potential confounders, the factors noted to be independently associated with the presence of comorbidities were advanced age, family history of comorbidity, normal weight or underweight, and cancer treatment for more than 6 months\' duration.
UNASSIGNED: The high prevalence of comorbidities among patients with cancer suggests the need for an integrated system of care and management as the comorbidities affect the overall management of cancer treatment and care.

UNASSIGNED: Inflammation has been associated with an increased risk for cancer development, while innate immune system activation could counteract the risk for malignancies. Familial Mediterranean fever (FMF) is a severe systemic inflammatory condition and also represents the archetype of innate immunity deregulation. Therefore, the aim of this study is to investigate the risk for cancer development in FMF.
UNASSIGNED: The risk ratio (RR) for malignancies was separately compared between FMF patients and fibromyalgia subjects, Still\'s disease patients and Behçet\'s disease patients. Clinical variables associated with cancer development in FMF patients were searched through binary logistic regression.
UNASSIGNED: 580 FMF patients and 102 fibromyalgia subjects, 1012 Behçet\'s disease patients and 497 Still\'s disease patients were enrolled. The RR for the occurrence of malignant neoplasms was 0.26 (95% Confidence Interval [CI.] 0.10-0.73, p=0.006) in patients with FMF compared to fibromyalgia subjects; the RR for the occurrence of malignant cancer was 0.51 (95% CI. 0.23-1.16, p=0.10) in FMF compared to Still\'s disease and 0.60 (95% CI. 0.29-1.28, p=0.18) in FMF compared to Behçet\'s disease. At logistic regression, the risk of occurrence of malignant neoplasms in FMF patients was associated with the age at disease onset (β1 = 0.039, 95% CI. 0.001-0.071, p=0.02), the age at the diagnosis (β1 = 0.048, 95% CI. 0.039-0.085, p=0.006), the age at the enrolment (β1 = 0.05, 95% CI. 0.007-0.068, p=0.01), the number of attacks per year (β1 = 0.011, 95% CI. 0.001- 0.019, p=0.008), the use of biotechnological agents (β1 = 1.77, 95% CI. 0.43-3.19, p=0.009), the use of anti-IL-1 agents (β1 = 2.089, 95% CI. 0.7-3.5, p=0.002).
UNASSIGNED: The risk for cancer is reduced in Caucasic FMF patients; however, when malignant neoplasms occur, this is more frequent in FMF cases suffering from a severe disease phenotype and presenting a colchicine-resistant disease.

BACKGROUND: International health policies and researchers have emphasized the value of evaluating patient-reported outcomes (PROs) in clinical studies. However, the characteristics of PROs in adult tumor clinical trials in China remain insufficiently elucidated.
OBJECTIVE: This study aims to assess the application and characteristics of PRO instruments as primary or secondary outcomes in adult randomized clinical trials related to tumors in China.
METHODS: This cross-sectional study identified tumor-focused randomized clinical trials conducted in China between January 1, 2010, and June 30, 2022. The ClinicalTrials.gov database and the Chinese Clinical Trial Registry were selected as the databases. Trials were classified into four groups based on the use of PRO instruments: (1) trials listing PRO instruments as primary outcomes, (2) trials listing PRO instruments as secondary outcomes, (3) trials listing PRO instruments as coprimary outcomes, and (4) trials without any mention of PRO instruments. Pertinent data, including study phase, settings, geographic regions, centers, participant demographics (age and sex), funding sources, intervention types, target diseases, and the names of PRO instruments, were extracted from these trials. The target diseases involved in the trials were grouped according to the American Joint Committee on Cancer Staging Manual, 8th Edition.
RESULTS: Among the 6445 trials examined, 2390 (37.08%) incorporated PRO instruments as part of their outcomes. Within this subset, 26.82% (641/2390) listed PRO instruments as primary outcomes, 52.72% (1260/2390) as secondary outcomes, and 20.46% (489/2390) as coprimary outcomes. Among the 2,155,306 participants included in these trials, PRO instruments were used to collect data from 613,648 (28.47%) patients as primary or secondary outcomes and from 74,287 (3.45%) patients as coprimary outcomes. The most common conditions explicitly using specified PRO instruments included thorax tumors (217/1280, 16.95%), breast tumors (176/1280, 13.75%), and lower gastrointestinal tract tumors (173/1280, 13.52%). Frequently used PRO instruments included the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire-30, the visual analog scale, the numeric rating scale, the Traditional Chinese Medicine Symptom Scale, and the Pittsburgh Sleep Quality Index.
CONCLUSIONS: Over recent years, the incorporation of PROs has demonstrated an upward trajectory in adult randomized clinical trials on tumors in China. Nonetheless, the infrequent measurement of the patient\'s voice remains noteworthy. Disease-specific PRO instruments should be more effectively incorporated into various tumor disease categories in clinical trials, and there is room for improvement in the inclusion of PRO instruments as clinical trial end points.

UNASSIGNED: To report the clinical presentation, anterior segment optical coherence tomography features, treatment, and outcomes of ocular surface squamous neoplasia (OSSN) associated with pterygium.
UNASSIGNED: Retrospective interventional series of 14 cases in a 28-month study period.
UNASSIGNED: OSSN was coexistent with pterygium (n = 14) in < 1% of all pterygia (n = 7384). The mean age at the presentation of OSSN with pterygium was 49 years (median, 49 years; range, 36 to 71 years). Referral diagnosis included pterygium sans OSSN (n = 7, 50%), granuloma (n = 1, 7%), actinic keratosis (n = 1, 7%), and conjunctivitis (n = 1, 7%). All OSSNs were unilateral, and six patients (43%) had bilateral pterygia. Tumors arose from the nasal (n = 8, 57%), or temporal (n = 6, 43%) quadrants. The mean tumor diameter was 4 mm (median, 4 mm; range, 2 to 6 mm), and the mean thickness was 2 mm (median, 1 mm; range, 1 to 3 mm). The delineation between OSSN and pterygium could be identified on anterior segment optical coherence tomography (AS-OCT) in all (100%) cases. All patients received 1% topical 5-fluorouracil (5-FU), and complete tumor regression was achieved in 13 (93%) cases with a mean number of 2 cycles (median, two cycles; range, 1 to 4 cycles). There were no significant adverse effects. No tumor recurrence was noted over a mean follow-up period of 11 months (median 12 months; range, 1 to 4 months).
UNASSIGNED: AS-OCT allows accurate detection and mapping of tumor extent in OSSN with coexistent pterygium, and topical 5-FU yields excellent tumor control.
