Development and validation of a patient-reported outcome measure to assess symptom burden after chimeric antigen receptor T-cell therapy.

This cross-sectional study aimed to develop and validate a patient-reported outcomes (PROs) assessment tool to assess symptom burden and daily functioning in patients after chimeric antigen receptor (CAR) T-cell therapy, the MD Anderson Symptom Inventory (MDASI-CAR). The items were generated based on literature review, content elicitation interviews with patients, and clinician's review. The patients completed the MDASI core and module, single-item quality-of-life (QoL) measure and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29). The psychometric validation analysis was based on the acceptability after item reduction process. The final 10 MDASI-CAR module items included tremors, fever/chills, headache, balance, dizziness, attention, difficulty speaking, coughing, sexual dysfunction, and diarrhoea with high internal consistency (Cronbach's alpha: MDASI Core, 0.865; MDASI Interference, 0.915; CAR-T module, 0.746). The MDASI-CAR has excellent known-group validity that was demonstrated by differentiate patients based on patient's performance status (Cohen's d for MDASI core = -1.008, interference = -0.771, module = -0.835). Criterion validity was demonstrated by the significant correlations between the MDASI-CAR composite score, the single QoL item and the relevant domains on PROMIS-29 (all p < 0.05). This study established the MDASI-CAR module as a reliable and valid PRO tool for monitoring symptom burden after CAR T-cell therapy in patients with haematological malignancies. The findings need to be validated with a longitudinal design.

Patient-reported symptoms at discharge and risk of complications after gynecologic surgery.

OBJECTIVE: Current gaps in knowledge limit clinicians from fully implementing patient-reported outcomes in routine post-operative care. METHODS: This prospective study assessed symptoms via the gynecologic module of the MD Anderson Symptom Inventory (MDASI-PeriOp-GYN) in patients who underwent open laparotomy. RESULTS: At discharge, patient-reported moderate to severe (≥4 on a 0-10 scale) abdominal bloating or abdominal cramping, combined with length of stay of ≥4 days, were found to be associated with a higher risk of 30-day post-operative grade II-IV complications by the Clavien-Dindo system (all p values <0.01). Also, length of stay of ≥4 days and moderate to severe urinary urgency at discharge were found to be associated with the need for re-admission (all p values <0.01). CONCLUSION: This study defined the clinically meaningful symptoms that related to the risk of developing important complications after discharge from major open gynecological surgery.These findings support the integration of assessment of patient-reported outcomes into patient-centered post-operative care.

Estimating the optimal linear combination of predictors using spherically constrained optimization.

BACKGROUND: In the context of a binary classification problem, the optimal linear combination of continuous predictors can be estimated by maximizing the area under the receiver operating characteristic curve. For ordinal responses, the optimal predictor combination can similarly be obtained by maximization of the hypervolume under the manifold (HUM). Since the empirical HUM is discontinuous, non-differentiable, and possibly multi-modal, solving this maximization problem requires a global optimization technique. Estimation of the optimal coefficient vector using existing global optimization techniques is computationally expensive, becoming prohibitive as the number of predictors and the number of outcome categories increases. RESULTS: We propose an efficient derivative-free black-box optimization technique based on pattern search to solve this problem, which we refer to as Spherically Constrained Optimization Routine (SCOR). Through extensive simulation studies, we demonstrate that the proposed method achieves better performance than existing methods including the step-down algorithm. Finally, we illustrate the proposed method to predict the severity of swallowing difficulty after radiation therapy for oropharyngeal cancer based on radiation dose to various structures in the head and neck. CONCLUSIONS: Our proposed method addresses an important challenge in combining multiple biomarkers to predict an ordinal outcome. This problem is particularly relevant to medical research, where it may be of interest to diagnose a disease with various stages of progression or a toxicity with multiple grades of severity. We provide the implementation of our proposed SCOR method as an R package, available online at https://CRAN.R-project.org/package=SCOR .

COVID-19 infection and its consequences among surgical oncology patients: A systematic analysis, meta-analysis and meta-regression.

We conducted this meta-analysis to address the outcomes in cancer patients after oncologic surgery during COVID-19 pandemic. The primary endpoint was the COVID-19-related mortality rate. Higher body mass index was significantly and negatively associated with higher all-cause mortality and in-hospital COVID-19 infection rates. Male sex, preoperative respiratory disease, and smoking history were positively and significantly associated with increased all-cause mortality rates. Furthermore, male sex was positively and significantly associated with the COVID-19 infection rate.

Behavioral, Biochemical and Histopathological effects of Standardised Pomegranate extract with Vinpocetine, Propolis or Cocoa in a rat model of Parkinson's disease.

INTRODUCTION: Parkinsonism is a neurodegenerative disorder. Pomegranate (POM) has been previously shown to have a dopaminergic neuroprotective effect against parkinsonism. OBJECTIVE: The aim of the current study is to investigate the possible effect of POM in combination with each of vinpocetine, propolis, or cocoa in the treatment of parkinsonism disease even without being given as adjuvant to L-dopa . METHODS: Rats were divided into seven groups, one normal and six RT model groups. One of the RT groups (2.5 mg/kg/48 h/10 doses sc), for 20 days served as non-treated parkinsonism model, whereas the others were treated with either L-dopa (10 mg/kg, p.o./day) or with POM (150 mg/kg, p.o./day) together with each of the following; vinpocetine (VIN) (20 mg/kg, p.o./day), propolis (300 mg/kg, p.o./day), cocoa (24 mg/kg, p.o./day). Motor and cognitive performances were examined using four tests (catalepsy, swimming, Y-maze, open field). Striatal dopamine, norepinephrine, serotonin, GABA, glutamate, acetylcholinesterase, GSK-3ß, BDNF levels were assessed as well as MDA, SOD, TAC, IL-1ß, TNF-α, iNOs, and caspase-3. Also, histopathological examinations of different brain regions were determined. RESULTS: Treatment with L-dopa alone or with all POM combination groups alleviated the deficits in locomotor activities, cognition, neurotransmitter levels, acetylcholinesterase activity, oxidative stress, and inflammatory markers as well as caspase-3 expression induced by RT. CONCLUSION: Combinations of POM with each of VIN, propolis, or cocoa have a promising disease-modifying antiparkinsonian therapy even without being given as an adjuvant to L-dopa.

Assessment of physical function by subjective and objective methods in patients undergoing open gynecologic surgery.

OBJECTIVE: To evaluate the utility of patient-reported outcomes (PROs) to measure physical functioning in perioperative care for patients with gynecological (GYN) tumors. METHODS: 180 patients with GYN tumors undergoing open surgery participated in this longitudinal study. The physical functioning was measured by a subjective PRO tool, the Interference subscales of the MD Anderson Symptom Inventory (MDASI-I); as well as by an objective tool, the Timed Up & Go test (TUGT), perioperatively. Longer time (>20 s) needed to complete the TUGT was defined as "Prolonged". Patients completed EuroQoL-5D as well. The association between the scores of MDASI-I items and TUGT was assessed via the Spearman correlation coefficient. The known-group validity was assessed using the t-test and Cohen's D effect size. RESULTS: Compliance rates at preoperative, discharge and postoperative time points of MDASI-I were 98%, 95%, 96%; while TUGT completion rates were 92%, 75%, and 80%, respectively. Patients who had refused TUGT at discharge reported a significantly worse "MDASI-general activity" score compared to patients who completed TUGT (mean score of 7.00 vs. 5.38, P = 0.020). Patient-reported "Walking" on MDASI-I significantly differentiated patients with prolonged vs. those with frail/normal TUGT at discharge (mean score of 4.89 vs. 2.79, Cohen's d effect size = 0.82, P < 0.001). MDASI-I demonstrated excellent known-group validity per performance status and for the EuroQoL-5D subscales. CONCLUSION: Patient-reported physical functioning impairment after GYN surgery correspond with observed worse scores of the objective functioning measure test (TUGT). MDASI-I assessment represents a feasible and valid tool to evaluate functional status and warrants further implementation in the perioperative setting.

Self-Reported Trismus: prevalence, severity and impact on quality of life in oropharyngeal cancer survivorship: a cross-sectional survey report from a comprehensive cancer center.

OBJECTIVE: The purpose of this study was to estimate prevalence/severity of self-reported trismus, determine association with quality of life (QOL), and examine clinical risk factors in a large population of patients treated for oropharyngeal cancer. MATERIALS AND METHODS: A cross-sectional survivorship survey was conducted among patients who completed definitive treatment for oropharyngeal carcinoma, disease-free ≥ 1-year post-treatment (median survival, 7 years among 892 survivors). Associations between trismus and QOL were also analyzed using MDASI-HN, EQ-5D, and MDADI. Dietary and feeding tube status were also correlated to trismus status. RESULTS: Trismus was self-reported in 31%. Severity of trismus positively correlated (r = 0.29) with higher mean interference scores reflecting a moderate association with quality of life (p < 0.0001). There was a negative correlation for MDADI composite scores (r = - 0.33) indicating increased perceived dysphagia related to trismus severity (p < 0.0001). EQ-5D VAS scores were also negatively correlated with trismus severity (r = - 0.26, p < 0.0001). Larger T-stage (p ≤ 0.001), larger nodal stage (p = 0.03), tumor sub-site (p = 0.05), and concurrent chemoradiation (p = 0.01) associated with increased prevalence of trismus. Diet negatively correlated (r = - 0.27) with trismus severity (p = < 0.0001), and survivors with severe trismus were also more likely to be feeding tube-dependent. CONCLUSION: Severity of trismus appears to negatively impact quality of life and associate with various adverse functional outcomes in long-term oropharyngeal cancer survivorship. Trismus remains associated with advanced disease stages, tumor sub-site (tonsil), and addition of chemotherapy. Further investigation is merited for the dose-effect relationship to the muscles of mastication.

Minocycline for symptom reduction in patients with multiple myeloma during maintenance therapy: a phase II placebo-controlled randomized trial.

BACKGROUND: Patients with multiple myeloma (MM) experience substantial cancer/treatment-related symptom burden during maintenance therapy. This is a phase II randomized, double-blinded, placebo-controlled clinical trial to examine the effect of minocycline for symptom reduction by its potential anti-inflammatory effect. METHODS: Eligible MM patients for maintenance therapy were randomized to receive minocycline (100 mg twice daily) or placebo. The MD Anderson Symptom Inventory for MM (MDASI-MM) was used to assess multiple symptoms weekly during the trial. Clinician-rated toxicities and blood samples were prospectively collected. The effect size, area under the curve (AUC), and t tests were used to determine the symptom burden between treatment groups and identify the 5 most-severe MDASI-MM symptoms. The longitudinal analysis compared the changes in symptom severity and associated inflammatory markers between groups over time. RESULTS: Sixty-nine evaluable MM patients (33 from the intervention group and 36 from the placebo group) were included. No grade 3+ adverse events related to study medication were noted. The AUCs for the 5 worst MDASI-MM symptoms (fatigue, pain, disturbed sleep numbness/tingling, and drowsiness) were not significantly different between two arms. Regardless of group assignment, pain reduction was positively associated with decreased serum levels of soluble tumor necrosis factor-α receptors 1 and 2 during therapy (all P < 0.05). CONCLUSIONS: This pPhase II randomized study observed no statistically significant positive signal impact from minocycline on symptom reduction or inflammatory markers during maintenance therapy for MM, although using minocycline was feasible and had a low toxicity profile.

Symptom burden and its functional impact in patients with "symptomatic" relapsed or refractory multiple myeloma.

PURPOSE: Relapsed or refractory multiple myeloma (RRMM) is labeled "symptomatic" based on laboratory values, but not relevant to quantitative measure of patient's perspectives. This study aimed to describe symptom burden, health status, and quality of life in RRMM patients. METHODS: The cross-sectional study included 184 MM patients (141 RRMM cases and 43 MM patients on follow-up without diagnosis/treatment of RRMM disease as controls), while 64 RRMM patients also provided longitudinal patient-reported outcomes (PROs) data. Symptomatic status was based on clinical measures of disease activity. PROs included the MD Anderson Symptom Inventory multiple myeloma module (MDASI-MM), single-item quality of life (SIQOL), and EuroQol-5D (EQ-5D). Wilcoxon rank test and effect size were used for comparisons. Regression models were used to describe symptom trajectory and to identify predictors of high symptom burden during 3 months of RRMM therapy. RESULTS: Most patients were clinically identified as symptomatic (93%). RRMM patients tended to report more severe symptoms, with significantly lower QOL scores and more severe fatigue, poor appetite, and lower enjoyment of life compared with controls (all p < 0.05). In RRMM patients, lower hemoglobin and higher B-2 microglobulin levels significantly correlated with higher burdens of fatigue, pain, and muscle weakness and also with lower QOL and EQ-5D scores (all p < 0.05). During RRMM therapy, being female, with any comorbidity, ≥ 65 years old, and ≥ 5 years MM history, contributed to high symptoms burden and poor QOL status (each p < 0.05). CONCLUSIONS: MDASI-MM modules were sensitive to detect the RRMM-related symptoms burden, which correlated with objective clinical measures. RRMM patients reported a more compromised QOL.

Evaluation of aromatase inhibitor on radiation induced pulmonary fibrosis via TGF- ß/Smad 3 and TGF- ß/PDGF pathways in rats.

Radiation-induced pulmonary fibrosis (RIPF) is a known complication in cancer patients after getting thoracic radiotherapy. Aromatase inhibitors (AIs) as anastrozole have been used instead of tamoxifen for adjuvant endocrine treatment of postmenopausal women with hormone sensitive breast cancer. This study is to evaluate the concurrent treatment of anastrozole and RIPF in rats. Twenty four female Wistar rats were distributed into 4 groups: Control (C), Radiation group (R) (total dose 30 Gy in 10 fractions, 5 fractions/week), anastrozole group (A) (0.003 mg/200 g body weight) orally for 14 consecutive days, and Radiation + anastrozole group (R + A). Radiation exposure resulted in a significant increase (p < 0.05) in pulmonary Transforming growth factor-beta 1 (TGF-ß), SMAD family member 3 (Smad3), Platelet-derived growth factor (PDGF), malondialdehyde (MDA), Total nitrate/nitrite (NO), interleukin 1ß (IL-1ß) and interleukin 6 (IL-6) compared to the control group. While, significant decreases (p < 0.05) in superoxide dismutase (SOD) activity, reduced glutathione (GSH) and connective tissue growth factor (CTGF) were observed in lung tissue. These alterations were minimized by anastrozole intervention. Also, anastrozole markedly hindered the lung histopathological changes observed after radiation. Concomitant use of anastrozole with radiation seems to attenuate radiation-induced pulmonary toxicity via TGF-ß/Smad 3 and TGF-ß/PDGF pathways in rats.

Distance learning impact on the English language teaching during COVID-19.

These days, distance learning has almost completely replaced traditional teaching methods due to the COVID-19 pandemic and the introduction of quarantine measures. A sharp rise in interest in distance learning methodology has raised a number of new questions and challenges. This research examines changes in the training process and cognitive abilities and academic performance during the coronavirus pandemic. Students of the I.M. Sechenov University and Al Ain University were surveyed (103) during classroom and distance English learning before and during the COVID-19. Three samples of the average values of the respondents' self-assessment of academic performance, cognitive abilities (namely concentration and memory), progress in performing oral assignments, progress in performing written assignments, ability to absorb information while reading and by ear; general health condition during the training and were obtained and tested for the Gaussian distribution law compliance. All of the rates studied fell during distance learning during a pandemic compared to distance learning outside a pandemic. However, it should be noted that they still turned out to be higher than the marks obtained in classroom teaching. Students were interviewed for possible factors influencing the reviewed teaching modes effectiveness (the survey showed that these factors are an increase in the amount of leisure time, ability to take breaks more often, more comfortable learning environment, no need to spend time on the road to the university).

Single-item discrimination of quality-of-life-altering dysphagia among 714 long-term oropharyngeal cancer survivors: Comparison of patient-reported outcome measures of swallowing.

BACKGROUND: Two patient-reported outcomes (PROs) of swallowing and their correlation to quality of life (QOL) were compared in long-term survivors of oropharyngeal cancer (OPC). METHODS: Scores on the single dysphagia item from the 28-item, multisymptom MD Anderson Symptom Inventory-Head and Neck (MDASI-HN-S) were compared with scores on the dysphagia-specific composite MD Anderson Dysphagia Inventory (MDADI) and the EuroQol visual analog scale (EQ-VAS) in 714 patients who had received definitive radiotherapy ≥12 months before the survey. An MDASI-HN-S score ≥6 and an MDADI composite score <60 were considered representative of moderate/severe swallowing dysfunction. RESULTS: Moderate/severe dysphagia was reported by 17% and 16% of respondents on the MDASI-HN-S and the composite MDADI, respectively. Both swallow PROs were predictive of QOL, and the MDASI-HN-S model was slightly more parsimonious for the discrimination of EQ-VAS scores compared with MDADI scores (Bayesian information criteria, 6062 vs 6076, respectively). An MDASI-HN-S cutoff score of ≥6 correlated best with a declining EQ-VAS score (P < .0001) and was associated with increased radiotherapy dose to several normal swallowing structures. CONCLUSIONS: In this cohort, the single-item MDASI-HN-S performed favorably for the discrimination of QOL compared with the multi-item MDADI. A time-efficient model for PRO measurement of swallowing is proposed in which the MDADI may be reserved for patients who score ≥6 on the MDASI-HN-S.

Usefulness of surveillance imaging in patients with head and neck cancer who are treated with definitive radiotherapy.

BACKGROUND: The current study was performed to assess the efficacy of surveillance imaging in patients with head and neck cancer (HNC) who are treated definitively with radiotherapy. METHODS: Eligible patients included those with a demonstrable disease-free interval (≥1 follow-up imaging procedure without evidence of disease and a subsequent visit/imaging procedure) who underwent treatment of HNC from 2000 through 2010. RESULTS: A total of 1508 patients were included. The median overall survival was 99 months, with a median imaging follow-up period of 59 months. Of the 1508 patients, 190 patients (12.6%) experienced disease recurrence (107 patients had locoregional and 83 had distant disease recurrence). A total of 119 patients (62.6%) in the group with disease recurrence were symptomatic and/or had an adverse clinical finding associated with the recurrence. Approximately 80% of patients with locoregional disease recurrences presented with a clinical finding, whereas 60% of distant disease recurrences were detected by imaging in asymptomatic patients. Despite the earlier detection of disease recurrence via imaging, those patients in the group of patients with clinically detected disease recurrence were significantly more likely to undergo salvage therapy compared with those whose recurrence was detected on imaging (odds ratio, 0.35). There was no difference in overall survival noted between those patients with disease recurrences that were detected clinically or with imaging alone. Approximately 70% of disease recurrences occurred within the first 2 years. In those patients who developed disease recurrence after 2 years, the median time to recurrence was 51 months. After 2 years, the average number of imaging procedures per patient for the detection of a salvageable recurrence for the imaging-detected group was 1539. CONCLUSIONS: Surveillance imaging in asymptomatic patients with HNC who are treated definitively with radiotherapy without clinically suspicious findings beyond 2 years has a low yield and a high cost. Physicians ordering these studies must use judicious consideration and discretion.

Modeling symptom drivers of oral intake in long-term head and neck cancer survivors.

PURPOSE: This study examined the relationship between self-reported symptom severity and oral intake in long-term head and neck cancer (HNC) survivors. METHODS: An observational survey study with retrospective chart abstraction was conducted. HNC patients who had completed an MD Anderson Symptom Inventory-Head and Neck (MDASI-HN) questionnaire and also had clinician graded oral intake ratings (Functional Oral Intake Scale [FOIS]) were included. Correlation coefficients were computed. FOIS scores were regressed on MDASI-HN symptom items using stepwise backwards elimination for multivariate models. RESULTS: One hundred and fifty-two survey pairings were included in the analysis (median 44 months follow-up, range 7-198). Per FOIS, 28% of survivors maintained a total oral diet with no restrictions, 67% reported a restricted oral diet (without tube), 3% were partially tube-dependent with some oral intake, and 2% were NPO. Of the 22 symptom items, the most severe items in decreasing order were dry mouth, difficulty swallowing\chewing, problems with mucus, tasting food, and choking/coughing. Significant bivariate correlations, after Bonferroni correction for multiple comparisons, were present for 8 of 22 symptoms with FOIS. On multivariate analysis, symptom severity for difficulty swallowing and problems with teeth/gums remained significantly associated with FOIS. CONCLUSIONS: Oral intake in HNC survivorship is a multidimensional issue and functional outcome that is impacted not only by dysphagia but also by dental status. Symptom drivers of oral intake likely differ in acute survivorship. Nonetheless, these findings highlight the lack of specificity in this end point and also the need for multidisciplinary supportive care to optimize oral intake in survivors.

Outcomes of patients diagnosed with carcinoma metastatic to the neck from an unknown primary source and treated with intensity-modulated radiation therapy.

BACKGROUND: There are few published studies to guide the treatment of carcinoma metastatic to the neck from an unknown primary (CUP). In this regard, the objective of the current study was to share the authors' current experience treating patients with CUP using intensity-modulated radiation therapy (IMRT), which principally targeted both sides of the neck, the nasopharynx, and the oropharynx. METHODS: This was a retrospective study in which an institutional database search was conducted to identify patients with CUP who received IMRT. Data analysis included frequency tabulation, survival analysis, and multivariable analysis. RESULTS: Two-hundred sixty patients met inclusion criteria. The most common lymph node category was N2b (54%). IMRT volumes included the entire pharyngolaryngeal mucosa in 78 patients, the nasopharynx and oropharynx in 167 patients, and treatment limited to the involved neck in 11 patients. Eighty-four patients underwent neck dissections. The 5-year overall survival, regional control, and distant metastases-free survival rates were 84%, 91%, and 94%, respectively. Over 40% of patients had gastrostomy tubes during therapy, and 7% patients were diagnosed with chronic radiation-associated dysphagia. Higher lymph node burden was associated with worse disease-related outcomes, and in subgroup analysis, patients with human papillomavirus-associated disease had better outcomes. No therapeutic modality was statistically associated with either disease-related outcomes or toxicity. CONCLUSIONS: Comprehensive IMRT with treatment to both sides of the neck and to the oropharyngeal and nasopharyngeal mucosa results in high rates of disease control and survival. The investigators were unable to demonstrate that treatment intensification with chemotherapy or surgery added benefit or excessive toxicity. Cancer 2018;124:1415-27. © 2018 American Cancer Society.

Characteristics and Outcomes of Stem Cell Transplant Patients during the COVID-19 Era: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aims to identify the outcomes of stem cell transplant (SCT) patients during the COVID-19 era. Pooled event rates (PER) were calculated, and meta-regression was performed. A random effects model was utilized. In total, 36 eligible studies were included out of 290. The PER of COVID-19-related deaths and COVID-19-related hospital admissions were 21.1% and 55.2%, respectively. The PER of the use of hydroxychloroquine was 53.27%, of the receipt of immunosuppression it was 39.4%, and of the use of antivirals, antibiotics, and steroids it was 71.61%, 37.94%, and 18.46%, respectively. The PER of the time elapsed until COVID-19 infection after SCT of more than 6 months was 85.3%. The PER of fever, respiratory symptoms, and gastrointestinal symptoms were 70.9, 76.1, and 19.3%, respectively. The PER of acute and chronic GvHD were 40.2% and 60.9%, respectively. SCT patients are at a higher risk of severe COVID-19 infection and mortality. The use of dexamethasone improves the survival of hospitalized SCT patients with moderate to severe COVID-19 requiring supplemental oxygen or ventilation. The SCT patient group is a heterogeneous group with varying characteristics. The quality of reporting on these patients when infected with COVID-19 is not uniform and further prospective or registry studies are needed to better guide clinical care in this unique setting.

Patient-reported outcomes after oncologic hepatic resection predict the risk of delayed readiness to return to intended oncologic therapy (RIOT).

BACKGROUND: Optimal surgical recovery is critical to readiness to return to intended oncologic therapy (RIOT). The current study defined the value of patient-reported outcomes (PROs) in predicting the risk for delayed RIOT after oncologic hepatic resection. METHODS: In a prospective longitudinal study, perioperative symptoms were assessed using a valid PRO assessment tool, the MD Anderson Symptom Inventory module for hepatectomy perioperative care (MDASI-PeriOp-Hep), for 4 weeks after surgery. The timed up and go test (TUGT) was administered before surgery, by discharge day, and at the first postoperative follow-up visit. Multivariate logistic regression analysis assessed the predictive value of PROs for delayed RIOT. RESULTS: We enrolled 210 patients and analyzed 148 patients who received adjuvant chemotherapy and contributed more than 3 PRO assessments postoperatively. About 36 percent of the patients had delayed RIOT (>5 weeks, range 1-14 weeks). MDASI scores for drowsiness, fatigue, dry mouth, and interference with general activity, walking, and work on day 7 after discharge and MDASI scores for incisional tightness, fatigue, dry mouth, shortness of breath, and interference with work on day 14 after discharge were associated with delayed RIOT (all P < 0.05). Walking and general activity items on the MDASI-Interference subscale on day 7 after discharge were highly correlated with prolonged TUGT scores at discharge (P < 0.01). CONCLUSION: We defined clinically meaningful PROs on MDASI-PeriOp-Hep after hepatic resection that predicted increased risk of delayed RIOT. These findings highlight the importance PROs for monitoring symptoms and functioning 1-2 weeks after discharge to be implementing into perioperative care.

Detection of Alteration in Carotid Artery Volumetry Using Standard-of-care Computed Tomography Surveillance Scans Following Unilateral Radiation Therapy for Early-stage Tonsillar Squamous Cell Carcinoma Survivors: A Cross-Sectional Internally-Matched Carotid Isodose Analysis.

Purpose: Radiation induced carotid artery disease (RICAD) is a major cause of morbidity and mortality among survivors of oropharyngeal cancer. This study leveraged standard-of-care CT scans to detect volumetric changes in the carotid arteries of patients receiving unilateral radiotherapy (RT) for early tonsillar cancer, and to determine dose-response relationship between RT and carotid volume changes, which could serve as an early imaging marker of RICAD. Methods and Materials: Disease-free cancer survivors (>3 months since therapy and age >18 years) treated with intensity modulated RT for early (T1-2, N0-2b) tonsillar cancer with pre- and post-therapy contrast-enhanced CT scans available were included. Patients treated with definitive surgery, bilateral RT, or additional RT before the post-RT CT scan were excluded. Pre- and post-treatment CTs were registered to the planning CT and dose grid. Isodose lines from treatment plans were projected onto both scans, facilitating the delineation of carotid artery subvolumes in 5 Gy increments (i.e. received 50-55 Gy, 55-60 Gy, etc.). The percent-change in sub-volumes across each dose range was statistically examined using the Wilcoxon rank-sum test. Results: Among 46 patients analyzed, 72% received RT alone, 24% induction chemotherapy followed by RT, and 4% concurrent chemoradiation. The median interval from RT completion to the latest, post-RT CT scan was 43 months (IQR 32-57). A decrease in the volume of the irradiated carotid artery was observed in 78% of patients, while there was a statistically significant difference in mean %-change (±SD) between the total irradiated and spared carotid volumes (7.0±9.0 vs. +3.5±7.2, respectively, p<.0001). However, no significant dose-response trend was observed in the carotid artery volume change withing 5 Gy ranges (mean %-changes (±SD) for the 50-55, 55-60, 60-65, and 65-70+ Gy ranges [irradiated minus spared]: -13.1±14.7, -9.8±14.9, -6.9±16.2, -11.7±11.1, respectively). Notably, two patients (4%) had a cerebrovascular accident (CVA), both occurring in patients with a greater decrease in carotid artery volume in the irradiated vs the spared side. Conclusions: Our data show that standard-of-care oncologic surveillance CT scans can effectively detect reductions in carotid volume following RT for oropharyngeal cancer. Changes were equivalent between studied dose ranges, denoting no further dose-response effect beyond 50 Gy. The clinical utility of carotid volume changes for risk stratification and CVA prediction warrants further evaluation.

Survival difference among adult and pediatric mediastinal yolk sac tumors cases: A meta-analysis of case reports.

BACKGROUND: Mediastinal Yolk sac tumors (YST) are rare and highly malignant extragonadal germ cell tumors with rapid growth and early metastases. We sought to conduct a meta-analysis of published case reports/case series to compare differences in survival, demographics, and treatment modalities between adult and pediatric patients with YST. METHODS: Ovid Embase, Cochrane, and Ovid Medline databases were searched for primary mediastinal pure YST cases. The primary outcome was overall survival (OS). Log-rank and Cox regression were used. This study is registered on PROSPERO (CRD42022367586). RESULTS: Among 846 studies, 87 met our inclusion criteria including 130 patients (Adults: 90 and Pediatrics: 40). About 41.5% of the patients were from the United States. The median age was 23.0 (Q1-Q3: 17.0-30.0), 88.5% were males, and (32.3%) were Asian. Stage II represented almost 40%. AFP was elevated in 96.9%. Respiratory distress was the presenting symptom in 65.4%. Chemotherapy, radiotherapy, and surgery were utilized in 84.6, 23.1, and 64.7% respectively. Median OS was 24 months (Adults: 23 months, Pediatrics: 25 months, P = 0.89). 3- and 5-year OS were 34.4% and 22.9% in adults and 41.5% and 41.5% in pediatrics, respectively. On multivariate analysis, anterior location of tumors, receipt of chemotherapy, and undergoing surgery were associated with better OS. CONCLUSION: Primary mediastinal YSTs are rare, but lethal neoplasms. Our meta-analysis showed that mediastinal YSTs mimic other non-seminomatous mediastinal GCTs in terms of clinical characteristics and available treatment options. Early diagnosis, neoadjuvant chemotherapy, and surgical resection are the key points for effective management and improved outcomes.
