797. A COMPARATIVE ANALYSIS ON THE EFFECTIVENESS OF DIFFERENT TREATMENT MODALITIES FOR ESOPHAGEAL CARCINOMA; A SYSTEMATIC REVIEW

Abstract Background Esophageal carcinoma; sixth most common cancer worldwide, presents a significant clinical challenge due to its aggressive nature and often late-stage diagnosis, resulting in poor prognosis and limited treatment options. Various treatment modalities, including surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy, are utilized in clinical practice. However, the optimal treatment strategy remains uncertain, as the comparative effectiveness of these modalities is not well-defined. Past studies have provided conflicting evidence, necessitating a comprehensive evaluation to guide clinical decision-making. Therefore, this systematic review aims to compare the efficacy and safety of different treatment modalities for esophageal carcinoma, with the objective of informing evidence-based treatment approaches and improving patient outcomes. Methods Total 350 publications from PubMed, EMBASE, Cochrane, Google Scholar and Semantic Scholar databases were identified on the effectiveness of different treatment modalities for esophageal carcinoma between 2000 and 2024. Following deduplication, two independent reviewers initially screened the articles for eligibility with titles and abstracts, and then, with complete articles. Bias assessment using GRADE guidelines for observational studies was done. Non-English studies, case-series/case-reports/essays/book-chapters/conference-abstracts/editorials/thesis/dissertations and studies without full-texts were excluded. Results Overall, the effectiveness of each treatment modality for esophageal carcinoma depends on various factors, including tumor stage, histology, patient characteristics, and treatment regimen. Combination approaches, such as chemoradiotherapy or multimodal therapy, are often used to maximize treatment efficacy and improve patient outcomes. Conclusion Multidisciplinary collaboration, personalized treatment approach, integration of novel therapies, such as immunotherapy and targeted therapy, into standard treatment regimens, survivorship care and advocate for further research to identify optimal treatment sequencing, identify predictive biomarkers of treatment response, and explore novel therapeutic targets to improve outcomes for patients with esophageal carcinoma is recommended.

Effects of different treatments for obstructive sleep apnea on temporomandibular joint: a randomized clinical trial

BackgroundIn recent years, obstructive sleep apnea (OSA) has been increasingly recognized as a significant health concern. No previous studies assessed the effect of recommended treatment modalities of patients with OSA on the temporomandibular joint (TMJ). The current study aimed to evaluate the effect of different treatment modalities of OSA, such as continuous positive airway pressure (CPAP), mandibular advancement device (MAD), and oral myofunctional therapy (OMT) on subjective symptoms, clinical, and radiographic signs of temporomandibular disorders.Patients & MethodsThis hospital-based prospective randomized controlled clinical trial study was approved by the institutional review board and formal patient consent, 39 OSA patients, ranging in age from 19 to 56 after confirmation with full night Polysomnography (PSG) with healthy TMJ confirmed clinically and radiographically with magnetic resonance imaging (MRI) were randomly allocated into three treatment groups. Group 1: 13 patients were managed with CPAP after titration, group 2: 13 patients were managed with digitally fabricated MAD, and group 3: 13 patients were managed with OMT. The following parameters were evaluated before and 3 months after the intervention. Pain using a visual analogue scale (VAS), maximum inter-incisal opening (MIO), lateral movements, and clicking sound of TMJ. MRI was done before and 3 months after the intervention.ResultsOut of the 83 patients enrolled, 39 patients completed the treatment. There were no statistically significant differences in lateral jaw movements or clicking, and no significant difference in MRI findings between the three studied groups before and after the intervention. The OMT group showed a statistically significant difference in pain (p = 0.001), and MIO (p = 0.043) where patients experienced mild pain and slight limitation in mouth opening after 3 months of follow-up in comparison to MAD and CPAP groups.ConclusionCPAP and MAD are better for preserving the health of TMJ in the treatment of OSA patients. While OMT showed mild pain and slight limitation of MIO (that is still within the normal range of mouth opening) compared to CPAP and MAD.Trial registrationThe study was listed on www.clinicaltrials.gov with registration number (NCT05510882) on 22/08/2022.

Adherence to Short-Duration Treatment (3HP) for Latent Tuberculosis among International Migrants in Manaus, Amazonas: Evaluation of the Efficacy of Different Treatment Modalities.

Migration, a multifaceted phenomenon, has a significant impact on health. Migrants perform similar movement patterns within their country of origin, in transit, and in the country of destination, thus making it difficult to monitor TB treatment throughout the journey. The objective was to compare the effectiveness of different treatment modalities in adherence to the short-term regimen for LTBI (3HP) among international migrants and refugees. This is a quasi-experimental study conducted in Manaus-AM. The study population was made up of international migrants. The certification and monitoring of medication intake employed three strategies: self-administration (SA), directly observed conventional therapy (DOT), and Video Telemonitoring System for Tuberculosis Treatment (VDOT). The VDOT group and SA group exhibited the lowest rate of treatment dropout or interruption at 16.1%, followed by the DOT group at 23.1%. The results suggest that the most effective strategy for ensuring adherence among migrants and refugees was VDOT (OR_adj 0.26; CI 0.7-0.94), suggesting that migrants may be more likely to adhere to and complete their treatment. The results show that relying on different treatment strategies, adapted to the individuals' needs and risk factors, is a viable and effective way of providing person-centered TB care.

Effectiveness of Different Treatment Modalities in Initial and Chronic Phases of Thyroid Eye Disease: A Systematic Review With Meta-analysis.

Thyroid eye disease (TED), a common extrathyroidal manifestation of Graves disease, poses significant management challenges due to potential disfigurement, visual impairment, and decreased quality of life. Uncertainties remain about the optimal treatment approach, especially regarding TED duration and its impact on outcomes. This meta-analysis evaluates the effects of various treatments on inflammatory markers and severity endpoints in TED, stratified by disease duration, distinguishing between treatments initiated within the first 6 months (initial phase) and those initiated thereafter (subacute/chronic phase). Following PRISMA guidelines, a systematic search of multiple electronic databases yielded 26 studies meeting predefined inclusion criteria. Methodological quality was assessed, and data were meticulously extracted and analyzed. In the initial phase, treatments like corticosteroids and teprotumumab showed significant improvements in clinical activity score, proptosis, and diplopia. In the subacute/chronic phase, the efficacy of methylprednisolone and teprotumumab is reduced. A "critical window" effect was observed, with treatments showing diminished efficacy after 6 months of TED duration. This meta-analysis highlights the importance of tailoring treatment strategies based on TED duration, emphasizing early interventions to maximize benefits. The findings guide clinicians in selecting optimal treatments and underscore the need for further research to refine evidence-based approaches, ultimately enhancing patient outcomes and quality of life.

Statistical Analysis on the Effect of Treatment on Blood Pressure Before and After Treatment in General Hospital Takum Using Paired T-Test

Hypertension is a preval_ent health condition worldwide, posing a significant risk for cardiovascular diseases. This study investigates the effect of treatment on blood pressure in individuals with hypertension, aiming to compare blood pressure levels before and after treatment, eval_uate the effectiveness of different treatment modalities, and assess the impact of treatment on other health outcomes. A quasi-experimental design is utilized, with participants recruited through convenience sampling. Data on blood pressure measurements are collected from medical records, and descriptive statistics and paired t-tests are used for data analysis. The results indicate a significant decrease in blood pressure levels after treatment, supporting the effectiveness of lifestyle modifications and pharmacological interventions in managing, emphasizing the importance of early detection and individualized treatment plans. Future research should focus on exploring the long-term effect of treatment and optimizing treatment strategies for specific patient populations.

Effects of different treatment modalities on cardiovascular disease in ARR-positive hypertensive patients.

Data on the prognosis of clinically undiagnosed hypertensive patients who are aldosterone-to-renin ratio (ARR) positive are still scarce. Therefore, we investigated the clinical characteristics of clinically undiagnosed hypertensive patients who were ARR-positive and the influence of their different treatments on the occurrence and development of complications. A total of 285 hypertensive patients data with ARR ≥ 3.8 in the Second People's Hospital of Huai'an from January 2019 to December 2021 were collected, and 135 undiagnosed hypertensive patients were ultimately included in the analysis. According to their treatment strategy in various clinical departments, 135 patients were divided into the operation, spironolactone and control groups. Then, the clinical characteristics and the occurrence and development of complications in the three groups were compared. The results suggested that: (1) Only 34 (11.9%) of 285 hypertensive patients with ARR ≥ 3.8 were clearly diagnosed with Primary aldosteronism (PA) through functional tests, and the blood pressure (BP) compliance rate was only 50.30% during follow-up. (2) Based on exclusion criteria, 135 undiagnosed hypertensive patients were eventually included in the analysis. Patients in the surgery group had lower blood potassium levels and higher aldosterone levels than those in the other two groups, and their risk of new cerebrovascular complications was lower than that of the patients in the spironolactone group. (3) The risk of new cerebrovascular complications in the spironolactone group was 9.520 times higher than that of the control group, and this risk mainly occurred in patients with ARR values of 3.8-5.7. On the whole, surgery remains a good option for hypertensive patients with severe hyperaldosteronism and hypokalemia and those unable to undergo confirmatory tests; however, spironolactone therapy in patients with clinically undiagnosed hypertension, especially those with 3.8 ≤ ARR < 5.7, confered a higher risk of new cerebrovascular complications.

Effect of different treatment modalities on the prognosis of stage IV epithelial ovarian cancer: analysis of the SEER database

BackgroundThe prognosis of advanced ovarian cancer is often poor. Although there are several treatment options for stage IV epithelial ovarian cancer, it is not clear which treatment will benefit the patient’s prognosis.We conducted an analysis using the SEER database to compare the impact of different treatment modalities on the prognosis of advanced ovarian cancer.MethodsThe present study conducts a retrospective analysis of relevant data from the SEER database pertaining to patients diagnosed with stage IV epithelial ovarian cancer between 2011 and 2020 (n = 5345). Statistical methods including Kaplan-Meier curves, log-rank tests, and Cox regression analysis are employed to ascertain the impact of different treatment regimens on the prognosis of patients with stage IV epithelial ovarian cancer.ResultsAmong patients with stage IV epithelial ovarian cancer, age ≥ 60 and the presence of lung metastases or multiple metastases were identified as poor prognostic factors. Conversely, being Asian or Pacific Islander, married, and testing negative for CA125 were associated with favorable prognoses. In terms of the choice of treatment for patients, surgery plus chemotherapy was the best treatment modality, and timely surgery could significantly improve the prognosis of patients, but there was no difference between chemoradiotherapy alone and the surgery group among patients with lung metastases.ConclusionThe prognosis of patients with stage IV epithelial ovarian cancer is influenced by many factors. In terms of the choice of treatment, patients with surgery plus chemotherapy have the best prognosis. In cases where lung metastases are inoperable, a combination of radiotherapy and chemotherapy can be used. In other cases, radiotherapy does not improve outcomes in patients with stage IV epithelial ovarian cancer. This study provides a basis for the choice of treatment for patients with stage IV epithelial ovarian cancer.

An NCDB analysis of patient treatment trends in soft tissue angiosarcoma.

e23563 Background: Angiosarcoma is a rare subtype of soft tissue sarcoma associated with a generally poor prognosis and high mortality rate. Median survival of patients with angiosarcoma typically ranges from 15 to 24 months, with a 5-year survival of 12-33%. Angiosarcomas have a high propensity for local recurrence, metastasis, and multiple organ involvement as they originate from vascular endothelial cells. Though surgical excision currently plays a central role in the treatment of angiosarcoma, no significant study has analyzed NCDB for treatment trends in these patients. This study aims to characterize the effect of different treatment modalities on overall survival of angiosarcoma patients. Methods: The National Cancer Database (NCDB) was used to identify patients diagnosed with angiosarcoma from 2004 to 2020 using histology code 9120 as assigned by the Commission on Cancer Accreditation program. Kaplan-Meier, ANOVA, Chi-Square, Cox Proportional Hazards and Logistic Regression tests were performed, and data were analyzed using SPSS version 29. Statistical significance was set at α = 0.05. Results: 3560 patients with angiosarcoma of the soft tissue were queried. The most common primary site for a tumor was the head, neck, or face (920 patients, 31.3%). Of the initial sample, 1889 ( 53.1%) patients received surgery alone, 450 ( 12.6%) patients received adjuvant chemotherapy, 55 ( 1.54%) received adjuvant radiation, and 30 ( 0.84%) patients received adjuvant chemoradiation. Surgery alone conferred the greatest median survival; no surgery conferred the least ( 31.4 months vs. 7.2 months; p &lt; 0.001). In the crude and adjusted logistic regression models, combined chemoradiation (OR = .210; 95% CI:.100-.400) and surgery alone were associated with the lowest odds of death (OR = .271; 95% CI: .224-.329) relative to no surgical procedure of the primary site. This finding persisted once the model was adjusted for age, stage, and tumor size. Surgery alone conferred the lowest hazard ratio (HR = .352; 95% CI: .323-.384) relative to no surgery. Conclusions: In angiosarcoma patients, surgical excision at the primary site alone was associated with the greatest median survival and the lowest hazard ratio. Additionally, angiosarcoma patients who did not receive surgery had the least median survival. Surgery with adjuvant chemoradiation and surgery alone had the lowest odds of death. These findings affirm that surgical excision at the site of the primary tumor plays a key role in increasing the survival of angiosarcoma patients. Further research is necessary in characterizing treatment trends in angiosarcoma patients to supplement current standardized treatment protocols and improve the mortality of this lethal cancer.

Effect of different treatment modalities on the prognosis of patients with stage IIIC cervical cancer.

To compare the effects of different treatments on the prognosis of patients with stage IIIC cervical cancer and to identify the main influencing factors to predict the outcomes of patients. In this study, a total of 1763 patients with stage IIIC cervical cancer from 2010-2015 were retrospectively analyzed, and these patients were divided into the radical radiotherapy ± chemotherapy group (877 patients) and the radical surgery + radiotherapy ± chemotherapy group (886 patients) according to the treatment methods. The survival differences between the two groups were compared using the Kaplan-Meier method. Unifactorial and multifactorial COX analyses screened the clinical factors affecting the prognosis. The nomogram was constructed, and the accuracy of the line graph was verified using the C-index, calibration, and ROC (receiver operator characteristic curve, ROC). Age, race, T-stage, pathologic type, mass size, whether or not they underwent surgery, and whether or not they received radiotherapy were independent factors affecting Overall Survival (OS). For all patients with TxN1M0 in cervical cancer stage IIIC, radical synchronized radiotherapy was better than the radical surgery group (p<0.0001). After comparing the tumor size breakdown, it could be found that in the T1N1M0, T2N1M0, and T3N1M0 groups, none of the OS in the surgical group achieved an improvement in OS compared with that in the non-surgical group (p>0.05). In patients with stage IIIC cervical cancer, OS did not improve in the radical surgery group compared with the radical simultaneous radiotherapy group. And surgery did not benefit patients' survival regardless of tumor size.

Effect of Different Treatment Modalities for Condylar Fractures in Childhood on Mandibular Symmetry and Temporomandibular Joint Function: A Retrospective Study.

In a retrospective study of the effects of different treatment modalities of condylar fractures in childhood on mandibular symmetry and temporomandibular function, the cases selected for this article were adult patients who had sustained a condylar fracture in childhood. The aim was to investigate the effects of condylar fractures in children on the development and function of the mandible and their specific manifestations after the completion of mandibular development. According to the different treatment modalities, the patients were divided into the conservative treatment group and the open surgical treatment group, and the effects of the 2 treatment modalities on the patients' condylar healing, the difference in growth ability, and the symmetry of the jaws were evaluated. The effects of different treatment modalities of children's condylar fracture on the growth, development, and function of the mandible were investigated using the Ai and Di, the grading of the imaging results, and the 3-dimensional CT fixation measurements from the aspects of both clinical examination and imaging examination. The 2 groups had condylar malalignment and condylar morphology abnormality, and there was one case of joint ankylosis in the surgical treatment group. There was a statistical difference in the evaluation of condylar reconstruction between the 2 groups, and the condylar reconstruction in the surgical treatment group was better than that in the conservative treatment, and there was a statistical difference between the condylar length, condylar width, condylar height, and depth of TMJ fossa between the healthy side and the affected side in the closed treatment group. There was a statistical difference in the height of the mandibular ascending branch between the healthy side and the affected side, and the unilateral condylar fracture was treated conservatively; the difference in the bony chin point deviation between the 2 groups was not statistically significant. In children, after conservative treatment of condylar fracture, the growth of condylar process is poor, and the condylar shape and position are not as good as surgical repositioning, but through the proliferation of temporomandibular joint fossa, it can make up for the insufficient height of condylar process, which has no effect on the symmetry of the mandible, and the surgical treatment can achieve good anatomical repositioning, which has a greater effect on the symmetry of the mandible than the conservative treatment.

Expanded analysis for patients with acute cholecystitis indicates outcomes vary based on COVID-19 status and treatment modality

BackgroundThe impact of different phases of COVID-19 infection on outcomes from acute calculous cholecystitis is not well understood. Therefore, we examined outcomes of acute cholecystitis during the COVID-19 pandemic, comparing the effect of different treatment modalities as well as COVID-19 infection status. We hypothesized that acute COVID-19 patients would have worse outcomes than COVID-negative patients, but there would be no difference between COVID-negative and COVID-recovered patients. MethodsWe utilized 2020-2023 National COVID Cohort Collaborative data to identify adults with acute calculous cholecystitis. Treatment (antibiotics-only, cholecystostomy tube, or cholecystectomy), and COVID-19 status (negative, active, or recovered) were collected. Treatment failure of non-operative managements was noted. Adjusted analysis using a series of generalized linear models controlled for confounders (age, sex, BMI, Charlson comorbidity index, severity at presentation, and year) to better assess differences in outcomes between treatment groups, as well as between COVID-19 groups. ResultsIn total, 32,433¥ patients were included: 29,749 COVID-negative, 2,112 COVID-active, and 572¥ COVID-recovered. COVID-active had higher rates of sepsis at presentation. COVID-negative more often underwent cholecystectomy. Unadjusted, COVID-active had higher 30-day mortality, 30-day complication, and longer LOS than COVID-negative and COVID-recovered. Adjusted analysis revealed cholecystectomy carried lower odds of mortality for COVID-active and COVID-negative patients, compared with antibiotics or cholecystostomy. COVID-recovered patients’ mortality was unaffected by treatment modality. Treatment failure from antibiotics was more common for COVID-negative patients. ConclusionsAcute cholecystitis outcomes are impacted by phase of COVID-19 infection and treatment modality. Cholecystectomy does not lead to worse outcomes for COVID-active and COVID-recovered patients, compared with non-operative treatments, thus these patients can be considered for cholecystectomy if their physiology is not prohibitive.

Prevalence and clinical outcome of isolated aortic stenosis: A single-center experience

ABSTRACT Background: There is a paucity of data regarding the prevalence and clinical outcomes of patients with isolated aortic stenosis (AS) in Saudi Arabia. Aim: Study investigates the prevalence AS and the effects of different treatment modalities on patients’ symptoms. Materials and Methods: This retrospective cohort study included patients diagnosed with isolated trileaflet AS between October 2015 and October 2018. Of 2300 patients who presented to our institution with valvular heart disease, 107 (4.7%) had isolated trileaflet AS. Results: The patients’ median age was 76 years (range 67–82). Dyspnea was the most common presenting symptom (n = This 86, 80.4%). The mean aortic valve area was 0.995 ± 0.35 mm2. Six patients (5.6%) had mild, 44 (41.1%) had moderate, and 57 (53.3%) had severe AS. Twenty-three patients with moderate/severe AS underwent surgery (22.8%), 24 patients underwent transcatheter valve intervention (TAVI) (23.8%), and 54 patients received medical treatment (53.5%). Marked symptom improvement was observed in patients who had surgery (n = 20, 86.96%), TAVI (n = 18, 75%), and medical treatment (n = 11, 18.33%) (P &lt; 0.001). The factors affecting symptom improvement were surgery (odds ratio [OR] 21.97 [95% confidence interval (CI): 4.79–100.7]; P &lt; 0.001) and TAVI (OR 9.27 [95% CI: 2.38–36.08]; P = 0.001). Conclusions: A prevalence of 4.7% was found for isolated trileaflet AS in patients who presented to our institution with valvular heart disease. Symptoms improved in patients who received interventional approaches compared with those who received medical management. Medical management should be strictly reserved for patients who cannot tolerate surgical or transcatheter aortic valve replacement.

Spontaneous and Treatment-Related Changes of Serum Calcitonin in Medullary Thyroid Cancer: Long-Term Experience in a Patient With Multiple Endocrine Neoplasia Type 2B.

Medullary thyroid carcinoma (MTC) in MEN2B syndrome is associated with germline RET mutation. Patients harboring de novo mutations are usually diagnosed at more advanced disease stages. We present a young woman with Met918Th mutation diagnosed with stage IV MTC at age 10 years. The disease progressed despite total thyroidectomy and multiple surgical interventions for cervical lymph node recurrences, leading to distant metastases in the fifth year after the initial diagnosis. Subsequently, she underwent five different types of tyrosine kinase inhibitor (TKI) treatments. The 17-year disease course was divided into periods defined by four surgical interventions and sequential treatment intervals with four multikinase (sunitinib, vandetanib, cabozantinib, and lenvatinib) and one RET-selective TKI (selpercatinib). Tumor growth for different phases of spontaneous development and drug treatment intervals was characterized by changes in serial log-transformed calcitonin measurements (n = 114). Three operations (one for calcitonin-producing adrenal pheochromocytoma) were associated with drops in calcitonin levels. All of the nonselective TKIs were stopped due to adverse effects. As reflected by the negative calcitonin doubling rate, the best treatment response was observed with selpercatinib, which was associated with an initial large drop followed by a decreasing calcitonin trajectory over 514 days without any major side effects. This case of MEN2B medullary thyroid cancer with long-term survival presents how the effectiveness of different treatment modalities can be estimated using log-transformed calcitonin levels. Furthermore, our experience supports the view that serial calcitonin measurements may be more sensitive than radiological follow-up in advanced MTC. Our patient also represents a new case of rarely reported calcitonin-producing pheochromocytomas.

Evaluation of the effect of different kinds of treatment modalities for temporomandibular joint pain and its relevance to chronic cervical pain: A randomized controlled trial.

The aim of this study was to evaluate the effect of different treatment modalities for temporomandibular joint (TMJ) pain and their relevance to chronic cervical pain after 12 months. This was a randomized controlled trial. Forty-eight participants with chronic cervical and TMJ pain were selected using research diagnostic criteria and randomized into four groups (n = 12), which included control, soft splints, transcutaneous electrical nerve stimulation (TENS), and low-level laser (LLL). The cervical and TMJ pain was recorded using visual analog scale (VAS) scores at baseline, 3 months, 6 months, and 12 months. Occlusal equilibration was done for all groups except for the control. The mean pain scores were statistically analyzed using one-way analysis of variance and posthoc test. The mean VAS scores in TMJ pain patients between the four groups at baseline and at final follow-up were 7.27 ± 1.29 in Group 1, 7.53 ± 0.70 in Group 2, 7.76 ± 0.80 in Group 3, and 7.61 ± 0.61 in Group 4. The mean difference between Groups 1 and 3, Groups 1 and 4, and Groups 2 and 3 was statistically significant (P < 0.00). Pearson correlation test yielded a mild and negative correlation between TMJ and cervical pain. TENS and LLL were found to be equally effective in reducing pain in the jaw joint region, followed by soft splints, and there was no correlation between TMJ and cervical pain.

Uncovering a novel DNA repair-related radiosensitivity model for evaluation of radiotherapy susceptibility in uterine corpus endometrial cancer

BackgroundUterine corpus endometrial cancer (UCEC) exhibit heterogeneity in their DNA repair capacity, which can impact their response to radiotherapy. Our study aimed to identify potential DNA repair-related biomarkers for predicting radiation response in UCEC. MethodsWe conducted a thorough analysis of 497 UCEC samples obtained from TCGA database. Using LASSO-COX regression analysis, we constructed a radiosensitivity signature and subsequently divided patients into the radiosensitive (RS) and the radioresistant (RR) groups based on their radiosensitivity index. The GSVA and GSEA were performed to explore functional annotations. The CIBERSORT and ESTIMATE algorithms were utilized to investigate the immune infiltration status of the two groups. Additionally, we utilized the Tumor Immune Dysfunction and Exclusion (TIDE), Immunophenotype Score (IPS), and pRRophetic algorithms to predict the effectiveness of different treatment modalities. ResultsWe constructed a radiosensitivity index consists of four DNA repair-related genes. Patients in the RS group demonstrated significantly improved prognosis compared to patients in the RR group when treated with radiotherapy. We observed that the RS group exhibited a higher proportion of the POLE ultra-mutated subtype, while the RR group had a higher proportion of the copy number high subtype. GSVA enrichment analysis revealed that the RS group exhibited enrichment in DNA damage repair pathways. Notably, the RS group demonstrated a higher proportion of naïve B cells and follicular helper T cells, while regulatory T cells (Tregs) and memory B cells were more abundant in the RR group. Furthermore, patients in the RS-PD-L1-high subgroup exhibited enrichment in immune-related pathways and increased sensitivity to immunotherapy, which is likely to contribute to their improved prognosis. Additionally, we conducted in vitro experiments to validate the expression of radiosensitivity genes in non-radioresistant (AN3CA) and radioresistant (AN3CA/IR) endometrial cancer cells. ConclusionsIn conclusion, our research successfully constructed a radiosensitivity signature with robust predictive capacity. These findings shed light on the association between immune activation, PD-L1 expression, and the response to immunotherapy in the context of radiotherapy.

Prognostic effects of different treatment modalities for hypopharyngeal squamous cell carcinoma: Experience of two tertiary hospitals in Southwestern China

BackgroundThe prognostic effects of different treatment modalities on patients with hypopharyngeal squamous cell carcinoma (HPSCC) remain unclear. MethodsHPSCC patients diagnosed and treated at either West China Hospital or Sichuan Cancer Hospital between January 1, 2009, and December 31, 2019, were enrolled in this retrospective, real-world study. Survival rates were presented using Kaplan–Meier curves and compared using log-rank tests. Univariable and multivariable Cox proportional hazards regression models were used to identify the predictors of overall survival (OS). Subgroup analyses were conducted for patients with advanced-stage HPSCC (stages III and IV and category T4). ResultsA total of 527 patients with HPSCC were included. Patients receiving SRC (surgery, radiotherapy [RT], and chemotherapy) showed the best OS (p < 0.0001). In comparison with RT alone, both surgery alone (all cases: hazard ratio [HR] = 0.39, p = 0.0018; stage IV cases: HR = 0.38, p = 0.0085) and surgery-based multimodality treatment (SBMT; all cases: HR = 0.27, p < 0.0001; stage IV cases: HR = 0.30, p = 0.00025) showed prognostic benefits, while SBMT also showed survival priority over chemoradiotherapy (CRT; all cases: HR = 0.52, p < 0.0001; stage IV cases: HR = 0.59, p = 0.0033). Moreover, patients who underwent surgery alone had comparable OS to those who underwent SBMT (all patients: p = 0.13; stage IV cases: p = 0.34), while CRT yielded similar prognostic outcomes as RT alone (all patients: p = 0.054; stage IV cases: p = 0.11). ConclusionsSurgery alone was comparable to SBMT and superior to RT/CRT in terms of OS in patients with HPSCC. We suggest that surgery should be encouraged for the treatment of HPSCC, even in patients with advanced-stage disease.

Treatment Modalities and Outcomes in Brainstem Cavernous Malformations: A Large Multicenter Observational Cohort Study.

Symptomatic brainstem cavernous malformations (BSCMs) pose a high risk of morbidity and mortality due to recurrent hemorrhage, warranting aggressive management. However, few studies have compared the effectiveness of different treatment modalities for BSCMs. We aimed to assess the association of treatment modalities with recurrent hemorrhage and neurological outcomes in patients with BSCM. We conducted a retrospective cohort study using an observational registry database covering population of southwest and southeast China. Adult patients with BSCM were included and followed up between March 1, 2011, to March 31, 2023. We compared outcomes between microsurgery and stereotactic radiosurgery (SRS) in propensity score-matched case pairs, incorporating demographic, medical history, and lesion characteristics. The outcomes studied included recurrent hemorrhage and poor prognosis (defined as a Glasgow Outcome Scale score, <4). Absolute rate differences and hazard ratios (HRs) with 95% CIs were calculated using Cox models. Among 736 diagnosed patients with BSCM, 96 (48 matched pairs) were included after exclusions and propensity score matching (mean age, 43.1 [SD, 12.1] years; 50% women). During the median 5-year follow-up, no significant differences in recurrent hemorrhage (4.2% [microsurgery] versus 14.6% [SRS], HR, 3.90 [95% CI, 0.46-32.65]; P=0.21) and poor prognosis (12.5% [microsurgery] versus 8.3% [SRS], HR, 0.29 [95% CI, 0.08-1.08]; P=0.07) were observed between microsurgery and SRS recipients. Furthermore, either microsurgery or SRS correlated with fewer recurrent hemorrhage (HR, 0.09 [95% CI, 0.02-0.39]; P=0.001; HR, 0.21 [95% CI, 0.07-0.69]; P=0.01) compared with conservative treatment. In this study, both microsurgery and SRS were safe and effective for BSCM, demonstrated comparable outcomes in recurrent hemorrhage and poor prognosis. However, interpretation should be cautious due to the potential for residual confounding. URL: https://www.chictr.org.cn/; Unique identifier: ChiCTR2300070907.

Effect of Different Treatment Modalities on Masseter Inhibitory Reflex in Patients with Sleep Bruxism: A Case-Control Study

Background: Sleep bruxism (SB) is a parafunctional oral habit that is frequently related to sleep arousals. The masseter inhibitory reflex (MIR) causes reflex inhibition of voluntary contractions of the elevator muscles induced by intense peri- or intraoral mechanical or electrical stimulations. This study aimed to investigate the changes in MIR of patients with SB, and the effect of different treatment modalities on MIR. Methods: In this case-control study, 100 individuals were randomly assigned to four groups (n=25) of conservative treatment (G1), occlusal splint treatment (G2), low-level laser therapy (LLLT) treatment (G3); and control (G4). The MIR was tested in all participants before and one month after treatment. Results: All MIR components of the patients had longer right and left SP1 and right and left SP2 latencies (P=0.017, P=0.043, P&lt;0.001, and P=0.04, respectively), and shorter right and left SP1 and right and left SP2 durations (P=0.021, P=0.021, P&lt;0.001, and P&lt;0.001, respectively) as compared to the control group. The right SP1 and SP2 latencies were prolonged in G3 versus G1 and G2 (P=0.026 and P&lt;0.001, respectively); whereas, the left SP2 latency was prolonged in G2 compared with G1. The right and left SP2 duration was not significantly different among the three treated groups. The left SP1 duration was not significantly different among the three treated groups. Gender had no effect on MIR parameters. Conclusion: SB patients had an abnormal MIR response. LLLT was the most effective compared to other treatment modalities.

Long-term Effects of Kidney Transplantation Compared With Dialysis on Intima-media Thickness in Children-Results From the 4C-T Study.

Children requiring kidney replacement therapy experience high burden of cardiovascular (CV) disease leading to increased mortality. Intima-media thickness (IMT) indicating atherosclerosis is a validated surrogate marker for future CV events. We investigated the effect of different treatment modalities (dialysis, preemptive kidney transplantation (KTx), late KTx after dialysis) on IMT by multivariable linear mixed-effect modeling. Patients were enrolled in a prospective cohort study. A total of 261 analyzed children had a mean follow-up of 3 y. Children after preemptive and late KTx had lower levels of IMT when compared with dialysis. Using an interaction term, a significant progression of IMT over time was seen during dialysis (β = 0.0053 mm/y, P = 0.004). IMT before the start of therapy was the most influential determinant in all models. Low IMT was associated with maintenance steroid treatment after preemptive KTx. High IMT on dialysis was associated with higher systolic blood pressure, lower body mass index, lower serum albumin, and lower bicarbonate. IMT remained rather stable in children several years after KTx. In contrast, children on dialysis had higher IMT values, which increased over time. In these children, blood pressure control, calorie and protein intake, and acid-base homeostasis seem important. Taken together, children might profit from early transplantation to limit accumulation of CV risk.

Effect of different treatment modalities on ovarian cancer patients with liver metastases: A retrospective cohort study based on SEER.

To examine the trends in morbidity and mortality among ovarian cancer patients with liver metastases, and investigate the impact of different treatments on both overall survival (OS) and cancer-specific survival (CSS). 2,925 ovarian cancer patients with liver metastases from Surveillance, Epidemiology, and End Results 2010-2019 were included. The primary endpoint was considered as OS and CSS. We conducted trend analysis of the incidence, OS and CSS rates of liver metastases in ovarian cancer. Univariate and multivariate COX proportional risk models were used to investigate the association between different treatment methods and OS, and univariate and multivariate competing risk models were employed to evaluate the impact of treatment methods on CSS. At the end of follow-up, 689 patients remained alive. The OS and CSS rates were 76.44% and 72.99% for all patients, respectively. There was a significant decreasing trend in the incidence [average annual percent change (AAPC) = -2.3, 95% confidence interval (CI): -3.9, -0.7], all-cause mortality (AAPC = -12.8, 95% CI: -15.6, -9.9) and specific mortality (AAPC = -13.0, 95% CI: -16.1, -9.8) rate of liver metastases in ovarian cancer. After adjusting all confounding factor, only receiving surgery was associated with OS [hazard ratio (HR) = 0.39, 95%CI: 0.31-0.48]/CSS (HR = 0.37, 95%CI: 0.30-0.47). Chemotherapy was found to be protective factor for OS (HR = 0.33, 95%CI: 0.30-0.37)/CSS (HR = 0.44, 95%CI: 0.39-0.50) of ovarian cancer patients, while not receiving surgery remained a risk factor. Additionally, the result of subgroup analyses also showed that only receiving surgery and chemotherapy still were significant protective factor of OS and CSS for patients without other distant metastases, with distant metastases to the bone, lung, brain or other organs, with bone metastasis, and with lung metastasis. Our research has elucidated a downward trend in morbidity and mortality rates among patients with liver metastases originating from ovarian cancer. Only receiving surgery and chemotherapy as therapies methods confer survival benefits to patients.
