RÉSUMÉ

CAR-T cell therapy offers a promising way for prolonged cancer remission, specifically in the case of blood cancers. However, its application in the treatment of solid tumors still faces many limitations. This review paper provides a comprehensive overview of the challenges and strategies associated with CAR-T cell therapy for solid tumors, with a focus on gynecological cancer. This study discusses the limitations of CAR-T therapy for solid tumor treatment, such as T cell exhaustion, stromal barrier, and antigen shedding. Additionally, it addresses possible approaches to increase CAR-T efficacy in solid tumors, including combination therapies with checkpoint inhibitors and chemotherapy, as well as the novel approach of combining CAR-T with oncolytic virotherapy. Given the lack of comprehensive research on CAR-T combination therapies for treating gynecological cancers, this review aims to provide insights into the current landscape of combination therapies for solid tumors and highlight the potential of such an approach in gynecology.

RÉSUMÉ

OBJECTIVE: To investigate the effects of the combined application of percutaneous vertebroplasty and zoledronic acid on bone mineral density (BMD), bone metabolism, neuropeptide Y (NPY) and prostaglandin E2 (PGE2) in elderly patients with osteoporotic lumbar vertebral compression fracture (OVCF). METHODS: The medical records of 118 elderly patients with OVCF who received treatment at our hospital from March 2018 to March 2020 were collected and analyzed retrospectively. Vertebral body height, spinal function, pain degree, and lumbar BMD were compared between the two groups upon admission and three years after the operation. Additionally, the levels of bone-specific alkaline phosphatase (BALP), 25-hydroxyvitamin D (25-(OH)D), beta collagen degradation fragments (ß-CTx), neuropeptide Y (NPY), and prostaglandin E2 (PGE2) in the two groups were measured at admission and three years after the operation. Furthermore, complications in the two groups within three years after the operation were documented. RESULTS: After three years post-operation, the combination group showed a significantly greater improvement in vertebral body height compared to the control group (P<0.05). Moreover, the combination group exhibited a significantly lower Oswestry Disability Index (ODI) score compared to the control group (P<0.05). CONCLUSION: In elderly patients with OVCF, the combined use of zoledronic acid and percutaneous vertebroplasty is effective in improving lumbar function, BMD, and bone metabolism indices, while reducing pain and the levels of NPY and PGE2.

RÉSUMÉ

MIBC is a highly lethal disease, and the patient survival rate has not improved significantly over the last decades. UPPL is a cell line that can be used to recapitulate the luminal-like molecular subtype of bladder cancer and to discover effective treatments to be translated in patients. Here, we investigate the effects of combinational treatments of radiotherapy and immunotherapy in this recently characterized UPPL tumor-bearing mice. We first characterized the baseline tumor microenvironment and the effect of radiation, anti-PD-L1, and combinatorial treatments. Then, the mice were re-challenged with a second tumor (rechallenged tumor) in the contralateral flank of the first tumor to assess the immunological memory. Radiation slowed down the tumor growth. All treatments also decreased the neutrophil population and increased the T cell population. Anti-PD-L1 therapy was not able to synergize with radiation to further delay tumor growth. Furthermore, none of the treatments were able to generate immune memory. The treatments were not sufficient to induce a significant and lasting pool of memory cells. We show here that anti-PD-L1 treatment added to radiotherapy was not enough to achieve T cell-mediated memory in UPPL tumors. Stronger T cell activation signals may be required to enhance radiation efficacy in luminal-like bladder cancer.

RÉSUMÉ

BACKGROUND: Nephrectomy is the surgical removal of all or part of a kidney. When the aim of nephrectomy is to reduce tumor burden in people with established metastatic disease, the procedure is called cytoreductive nephrectomy (CN). CN is typically combined with systemic anticancer therapy (SACT). SACT can be initiated before or immediately after the operation or deferred until radiological signs of disease progression. The benefits and harms of CN are controversial. OBJECTIVES: To assess the effects of cytoreductive nephrectomy combined with systemic anticancer therapy versus systemic anticancer therapy alone or watchful waiting in newly diagnosed metastatic renal cell carcinoma. SEARCH METHODS: We performed a comprehensive search in the Cochrane Library, MEDLINE, Embase, Scopus, two trial registries, and other gray literature sources up to 1 March 2024. We applied no restrictions on publication language or status. SELECTION CRITERIA: We included randomized controlled trials (RCTs) that evaluated SACT and CN versus SACT alone or watchful waiting. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies and extracted data. Primary outcomes were time to death from any cause and quality of life. Secondary outcomes were time to disease progression, treatment response, treatment-related mortality, discontinuation due to adverse events, and serious adverse events. We performed statistical analyses using a random-effects model. We rated the certainty of evidence using the GRADE approach. MAIN RESULTS: Our search identified 10 records of four unique RCTs that informed two comparisons. In this abstract, we focus on the results for the two primary outcomes. Cytoreductive nephrectomy plus systemic anticancer therapy versus systemic anticancer therapy alone Three RCTs informed this comparison. Due to the considerable heterogeneity when pooling across these studies, we decided to present the results of the prespecified subgroup analysis by type of systemic agent. Cytoreductive nephrectomy plus interferon immunotherapy versus interferon immunotherapy alone CN plus interferon immunotherapy compared with interferon immunotherapy alone probably increases time to death from any cause (hazard ratio [HR] 0.68, 95% confidence interval [CI] 0.51 to 0.89; I²= 0%; 2 studies, 326 participants; moderate-certainty evidence). Assuming 820 all-cause deaths at two years' follow-up per 1000 people who receive interferon immunotherapy alone, the effect estimate corresponds to 132 fewer all-cause deaths (237 fewer to 37 fewer) per 1000 people who receive CN plus interferon immunotherapy. We found no evidence to assess quality of life. Cytoreductive nephrectomy plus tyrosine kinase inhibitor therapy versus tyrosine kinase inhibitor therapy alone We are very uncertain about the effect of CN plus tyrosine kinase inhibitor (TKI) therapy compared with TKI therapy alone on time to death from any cause (HR 1.11, 95% CI 0.90 to 1.37; 1 study, 450 participants; very low-certainty evidence). Assuming 574 all-cause deaths at two years' follow-up per 1000 people who receive TKI therapy alone, the effect estimate corresponds to 38 more all-cause deaths (38 fewer to 115 more) per 1000 people who receive CN plus TKI therapy. We found no evidence to assess quality of life. Immediate cytoreductive nephrectomy versus deferred cytoreductive nephrectomy One study evaluated CN followed by TKI therapy (immediate CN) versus three cycles of TKI therapy followed by CN (deferred CN). Immediate CN compared with deferred CN may decrease time to death from any cause (HR 1.63, 95% CI 1.05 to 2.53; 1 study, 99 participants; low-certainty evidence). Assuming 620 all-cause deaths at two years' follow-up per 1000 people who receive deferred CN, the effect estimate corresponds to 173 more all-cause deaths (18 more to 294 more) per 1000 people who receive immediate CN. We found no evidence to assess quality of life. AUTHORS' CONCLUSIONS: CN plus SACT in the form of interferon immunotherapy versus SACT in the form of interferon immunotherapy alone probably increases time to death from any cause. However, we are very uncertain about the effect of CN plus SACT in the form of TKI therapy versus SACT in the form of TKI therapy alone on time to death from any cause. Immediate CN versus deferred CN may decrease time to death from any cause. We found no quality of life data for any of these three comparisons. We also found no evidence to inform any other comparisons, in particular those involving newer immunotherapy agents (programmed death receptor 1 [PD-1]/programmed death ligand 1 [PD-L1] immune checkpoint inhibitors), which have become the backbone of SACT for metastatic renal cell carcinoma. There is an urgent need for RCTs that explore the role of CN in the context of contemporary forms of systemic immunotherapy.

RÉSUMÉ

BACKGROUND: The total glucoside of paeony (TGP) is recognized for its immunomodulatory properties and anti-inflammatory effects. This study evaluates the efficacy of TGP combined with oral mini-pulse therapy (OMP) and narrow-band ultraviolet B (NB-UVB) in treating active nonsegmental vitiligo (NSV). MATERIALS AND METHODS: The combination therapy was contrasted against those from a group treated solely with OMP and NB-UVB. Data from 62 patients undergoing TGP combination treatment and 55 without were analyzed over a 3-month period. After 6 months, the differences in recurrence rate were investigated by follow-up. RESULTS: The findings indicate that integrating TGP may yield superior outcomes compared to OMP + NB-UVB alone. Moreover, the patient's oxidative stress makers were significantly reduced after the treatment. The majority of patients in the TGP cohort exhibited enhanced skin pigmentation over the duration. Notably, no increase in side effects or recurrence was observed in this group. Especially, patients with vitiligo on their head and neck experienced pronounced improvements. CONCLUSION: The efficacy of the combination treatment group was better than that of the control group at 2 and 3 months, and there was no difference in recurrence rate and side effects, suggesting that TGP may continue to show efficacy in NSV for a longer period of time by reducing the level of oxidative stress, and is especially suitable for patients with head and neck lesions.

RÉSUMÉ

To evaluate the safety and efficacy of combining EW-7197 with irreversible electroporation (IRE) for improving wound healing, 16 male Sprague-Dawley rats were randomly divided into four groups of four rats each after dorsal excisional wound induction: sham control group; oral administration of EW-7197 for 7 days group; one-time application of IRE group; and one-time application of IRE followed by oral administration of EW-7197 for 7 days group. Measurement of wound closure rate, laser Doppler scanning, histological staining (hematoxylin and eosin and Masson's trichrome), and immunohistochemical analyses (Ki-67 and α-SMA) were performed to evaluate the efficacy. Fifteen of 16 rats survived throughout the study. Statistically significant differences in wound closure rates were observed between the combination therapy group and the other three groups (all P < 0.05). The degrees of inflammation, α-SMA, and Ki-67 were reduced in the EW-7197 and IRE monotherapy groups; however, not statistically significant. The fibrosis score exhibited significant reduction in all three treatment groups, with the most prominent being in the combination therapy group. This study concludes that oral administration of EW-7197 combined with IRE demonstrated effectiveness in improving skin wound in a rat excisional model and may serve as a potential alternative for promoting healing outcomes.

RÉSUMÉ

BACKGROUND: Non-invasive brain stimulation (NIBS) combined with cognitive training (CT) may have shown some prospects on improving cognitive function in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). However, data from clinical trials or meta-analysis involving NIBS combined with CT have shown controversial results. The aim of this systematic review and meta-analysis was to evaluate short-term and long-term effects of NIBS combined with CT on improving global cognition and other specific cognitive domains in patients with AD and MCI. METHODS: This systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five electronic databases including PubMed, Web of Science, EBSCO, Cochrane Library and Embase were searched up from inception to 20 November 2023. The PEDro scale and the Cochrane's risk of bias assessment were used to evaluate risk of bias and methodological quality of included studies. All statistical analyses were conducted with Review Manager 5.3. RESULTS: We included 15 studies with 685 patients. The PEDro scale was used to assess methodological quality with a mean score of 7.9. The results of meta-analysis showed that NIBS combined with CT was effective on improving global cognition in AD and MCI (SMD = 0.52, 95% CI (0.18, 0.87), p = 0.003), especially for patients accepting repetitive transcranial magnetic stimulation (rTMS) combined with CT (SMD = 0.46, 95% CI (0.14, 0.78), p = 0.005). AD could achieve global cognition improvement from NIBS combined with CT group (SMD = 0.77, 95% CI (0.19, 1.35), p = 0.01). Transcranial direct current stimulation (tDCS) combined with CT could improve language function in AD and MCI (SMD = 0.29, 95% CI (0.03, 0.55), p = 0.03). At evaluation follow-up, rTMS combined with CT exhibited larger therapeutic responses to AD and MCI in global cognition (SMD = 0.55, 95% CI (0.09, 1.02), p = 0.02). AD could achieve global cognition (SMD = 0.40, 95% CI (0.03, 0.77), p = 0.03) and attention/working memory (SMD = 0.72, 95% CI (0.23, 1.20), p = 0.004) improvement after evaluation follow-up from NIBS combined with CT group. CONCLUSIONS: Overall, NIBS combined with CT, particularly rTMS combined with CT, has both short-term and follow-up effects on improving global cognition, mainly in patients with AD. tDCS combined with CT has advantages on improving language function in AD and MCI. Future more studies need evaluate cognitive effects of NIBS combined with CT on other specific cognitive domain in patients with cognitive deterioration.

RÉSUMÉ

Therapeutic options for acne scars include subcision and suction with microdermabrasion, but these treatment modalities have not been studied in conjunction. To compare effectiveness of subcision alone versus subcision with suction for the treatment of facial acne scars. Randomized, split-faced, evaluator-blinded control trial. Participants underwent one subcision treatment on both sides of the face followed by 10 sessions of suction to one side. Photographs at baseline, 1-month, and 4-months were assessed. Primary outcome measures were the validated Acne Scar Severity Scale (ASSS) (0 = no acne scarring, 4 = severe), Acne Scar Improvement Grading Scale (ASIGS) (-100 to 100%), and modified Quantitative Global Scarring Grades (QGSG) (point-based questionnaire instrument), as well as subject preference. Twenty-eight treatment areas and 154 treatments were analyzed. Dermatologist raters found no differences between subcision alone and subcision-suction at 1-month or 4-months. Mean subject-assessed percent improvement for subcision-suction was higher than that for subcision alone at 1-month (37% versus 24%, p = 0.04) but not at 4-months (p = 0.37). Subjects preferred combination therapy to monotherapy at 1-month (50% vs. 21%) and 4-months (43% vs. 21%). While blinded raters did not detect significant differences, subjects perceived combination treatment as working more quickly than monotherapy, and preferred combination treatment at all time points.Clinical trial registration NCT01696513 on Clinicaltrials.gov.

RÉSUMÉ

Loss and absence of melanocytes due to a number of factors is responsible for vitiligo; known to be the commonest disorder of pigmentation. The aim of the current work was to compare the efficacy and safety of excimer light with topical tacrolimus ointment 0.1% versus excimer light with topical bimatoprost gel 0.01% in treatment of facial vitiligo. The study was carried out on 48 patients presented with facial vitiligo. The patients were divided randomly using sealed envelope method into two groups (24 patients each). Group 1 were treated with excimer light plus topical tacrolimus ointment 0.1% and group 2 treated with excimer light plus topical bimatoprost gel 0.01%. Clinical improvement based on the quartile grading scale at the end of treatment did not show any statistically significant difference between groups. The majority of subjects in both groups experienced good to excellent improvement. Only 20.9% of patients in group 1 and 33.3% of subjects in group 2 achieved less than 50% repigmentation (p = 0.889). Our study demonstrated that 0.01% topical bimatoprost gel in combination with excimer light is considered safe and effective as treatment of nonsegmental facial vitiligo with comparable results to 0.1% tacrolimus.

RÉSUMÉ

Post-acne erythema (PAE) is a bothering skin condition that emerges from inflammatory acne and persists after its resolution. It is characterized by telangiectasia and erythematous macules. the role of 1064-nm Nd: YAG when combined with low-dose isotretinoin in the acne erythema treatment. forty-eight PAE patients were involved in the study. They were divided into two groups; group (A) patients administering a low dose of oral isotretinoin (10 mg/day) and underwent a total of six two-week interval sessions of 1064 ND-YAG laser treatment, group (B) patients administering a low dose of oral isotretinoin (10 mg/day) only. All adverse effects experienced during the course of therapy were documented, and photos were taken before the start of the treatment and following the end of the treatment duration. Following the completion of the therapeutic intervention, a significant improvement in clinical condition was observed in both groups, with more improvement in group (A) compared to group (B) as evidenced by a notable improvement in the score on the Clinician Erythema Assessment Scale (CEAS) and also a significant decrease in the mean value of optical density of the erythema. combined 1064-nm Nd: YAG with low-dose isotretinoin may be an efficient and secure line in the PAE treatment. Also, the combined therapy had superior results when compared to low-dose isotretinoin alone.

RÉSUMÉ

BACKGROUND: Macrovascular lesions are the main cause of death and disability in diabetes mellitus, and excessive accumulation of cholesterol and lipids can lead to long-term and repeated damage of vascular endothelial cells. Umbilical cord mesenchymal stem cells (UCMSCs) can attenuate vascular endothelial damage in type 1 diabetic mice, while Fufang Xueshuantong capsule (FXC) has a protective effect on endothelial function; however, whether FXC in combination with UCMSCs can improve T2DM macrovascular lesions as well as its mechanism of action are not clear. Therefore, the aim of this study was to reveal the role of FXC + UCMSCs in T2DM vasculopathy and their potential mechanism in the treatment of T2DM. METHODS: The control and T2DM groups were intragastrically administered with equal amounts of saline, the UCMSCs group was injected with UCMSCs (1×106, resuspended cells with 0.5 mL PBS) in the tail vein, the FXC group was intragastrically administered with 0.58 g/kg FXC, and the UCMSCs + FXC group was injected with UCMSCs (1×106) in the tail vein, followed by FXC (0.58 g/kg), for 8 weeks. RESULTS: We found that FXC+UCMSCs effectively reduced lipid levels (TG, TC, and LDL-C) and ameliorated aortic lesions in T2DM rats. Meanwhile, Nrf2 and HO-1 expression were upregulated. We demonstrated that inhibition of Nrf-2 expression blocked the inhibitory effect of FXC+UCMSCs-CM on apoptosis and oxidative stress injury. CONCLUSION: Our data suggest that FXC+UCMSCs may attenuate oxidative stress injury and macroangiopathy in T2DM by activating the Nrf-2/HO-1 pathway.

RÉSUMÉ

BACKGROUND: Acupuncture has been used for the treatment of chronic migraine, but high-quality evidence is scarce. We aimed to evaluate acupuncture's efficacy and safety compared to topiramate for chronic migraine. METHODS: This double-dummy randomized controlled trial included participants aged 18-65 years diagnosed with chronic migraine. They were randomly assigned (1:1) to receive acupuncture (three sessions/week) plus topiramate placebo (acupuncture group) or topiramate (50-100 mg/day) plus sham acupuncture (topiramate group) over 12 weeks, with the primary outcome being the mean change in monthly migraine days during weeks 1-12. RESULTS: Of 123 screened patients, 60 (mean age 45.8, 81.7% female) were randomly assigned to acupuncture or topiramate groups. Acupuncture demonstrated significantly greater reductions in monthly migraine days than topiramate (weeks 1-12: -2.79 [95% CI: -4.65 to -0.94, p = 0.004]; weeks 13-24: -3.25 [95% CI: -5.57 to -0.92, p = 0.007]). No severe adverse events were reported. CONCLUSIONS: Acupuncture may be safe and effective for treating chronic migraine. The efficacy of 12 weeks of acupuncture was sustained for 24 weeks and superior to that of topiramate. Acupuncture can be used as an optional preventive therapy for chronic migraine.

RÉSUMÉ

BACKGROUND: In absence of drug therapy options, standard treatment for spinocerebellar ataxia consists of symptomatic physiotherapy and speech therapy. New therapeutic options are urgently needed. Transcranial magnetic stimulation is a promising therapeutic option, but applicability is limited by lengthy duration of stimulation protocols. METHODS: In this randomized sham controlled clinical trial, patients were assigned to verum (n = 15) or sham (n = 18) cerebellar transcranial magnetic stimulation. To yield best possible treatment effects, both intervention groups received intensified physiotherapy for the duration of the study. RESULTS: Ataxia severity was reduced by 1.6 points on the Scale for assessment and Rating of Ataxia among patients in the verum group (p < 0.001). Clinical improvement was significantly larger in the verum group, compared to the sham group (p < 0.01). The treatment effect was mainly carried by improved appendicular coordination. Patients in the verum group also significantly improved in the 8 Meter Walk Test (p < 0.05) and PATA rate (p < 0.01). CONCLUSIONS: Cerebellar rTMS ameliorates ataxia severity in patient with spinocerebellar ataxia. Condensing treatment duration to only 5 days without reduction of treatment effects facilitates applicability and therefore broadens availability to larger patient populations.

RÉSUMÉ

Background: Combination therapy offers superior therapeutic results compared to monotherapy. However, the outcomes of combination therapy often fall short of expectations, mainly because of increased toxicity from drug interactions and challenges in achieving the desired spatial and temporal distribution of drug delivery. Optimizing synergistic drug combination ratios to ensure uniform targeting and distribution across space and time, particularly in vivo, is a significant challenge. In this study, cRGD-coated liposomes encapsulating optimized synergistic cepharanthine (CEP; a chemotherapy drug) and IR783 (a phototherapy agent) were developed for combined chemotherapy and photothermal therapy in vitro and in vivo. Methods: An MTT assay was used to evaluate the combination index of CEP and IR783 in five cell lines. The cRGD-encapsulated liposomes were prepared via thin-film hydration, and unencapsulated liposomes served as controls for the loading of CEP and IR783. Fluorescence and photothermal imaging were used to assess the efficacy of CEP and IR783 encapsulated in liposomes at an optimal synergistic ratio, both in vitro and in vivo. Results: The combination indices of CEP and IR783 were determined in five cell lines. As a proof-of-concept, the optimal synergistic ratio (1:2) of CEP to IR783 in 4T1 cells was evaluated in vitro and in vivo. The average diameter of the liposomes was approximately 100 nm. The liposomes effectively retained the encapsulated CEP and IR783 in vitro at the optimal synergistic molar ratio for over 7 d. In vivo fluorescence imaging revealed that the fluorescence signal from cRGD-CEP-IR783-Lip was detectable at the tumor site at 4 h post-injection and peaked at 8 h. In vivo photothermal imaging of tumor-bearing mice indicated an increase in tumor temperature by 32°C within 200 s. Concurrently, cRGD-CEP-IR783-Lip demonstrated a significant therapeutic effect and robust biosafety in the in vivo antitumor experiments. Conclusion: The combination indices of CEP and IR783 were successfully determined in vitro in five cell lines. The cRGD-coated liposomes encapsulated CEP and IR783 at an optimal synergistic ratio, exhibiting enhanced antitumor effects and targeting upon application in vitro and in vivo. This study presents a novel concept and establishes a research framework for synergistic chemotherapy and phototherapy treatment.

RÉSUMÉ

Vitiligo is considered an autoimmune disease, and its treatment is challenging. We assessed and compared the effect of fractional erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted delivery of platelet-rich plasma versus microneedling (Mn) with platelet-rich plasma (PRP) in enhancing skin repigmentation in localized stable vitiligo patients. In total, 40 patients with localized stable vitiligo were selected in a random manner into two similar groups (20 each). Group (A) was subjected to fractional Er:YAG laser combined with platelet-rich plasma and Group (B) was subjected to microneedling combined with platelet-rich plasma. The procedure was repeated every 2 weeks for up to 6 months. Each individual was assessed clinically utilizing Vitiligo Area Scoring Index (VASI). Fractional Er:YAG + PRP group achieved better pigmentation100% (excellent 30%, very good 15%, good 30% and satisfactory 25%) which is comparable to Mn + PRP where 80% of cases demonstrate repigmentation (20% very good, 10% good and 50% mild). When comparing the VASI scores for both groups after therapy to the baseline VASI, there was a statistically significant decrease [p = 0.001 for group(A) and 0.003 for group(B)]. Regarding the treatment side effects, there was significantly (p = 0.048) side effects among cases treated with microneedling group(B) (25%) than those fractional Er:Yag laser therapy group(A) (5%). Both forms of therapy demonstrated induction of repigmentation of vitiligo, but fractional Er:YAG laser efficacy is greater when combined with platelet-rich plasma.Clinical trials.gov identifier: NCT05511493.

RÉSUMÉ

Traditional Chinese medicine (TCM) has long been used to treat various diseases, including cerebral ischemia. The specific molecular mechanism of TCM in the treatment of cerebral ischemia, however, is still unclear. This study investigated the effects of gastrodin, electroacupuncture and their combination on cerebral ischemic rats. We used Nissl staining, immunohistochemical staining and immunoblotting to detect the expression changes of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) in the frontal cortex. The results showed that the combination therapy of gastrodin and electroacupuncture significantly increased the number of Nissl-positive neurons and improved cell morphology compared with other groups. Mechanistically, we found that the combination of gastrodin and electroacupuncture treatment group can restore the abnormal morphology of neuronal cells caused by cerebral ischemia by rebalancing the expression levels of BDNF and IL-6. Our research indicates that gastrodin combined with electroacupuncture has a significant protective effect on cerebral ischemic injury in rats, possibly by regulating the expression of BDNF and IL-6. This combination therapy is superior to single-drug or electroacupuncture therapy.

RÉSUMÉ

INTRODUCTION AND PURPOSE: With a significant global impact, treatment of gastrointestinal (GI) cancers still presents with challenges, despite current multimodality approaches in advanced stages. Clinical trials are expanding for checkpoint inhibition (ICI) combined with radiation therapy (RT). This review intends to offer a comprehensive image of the current data regarding the effectiveness of this association, and to reflect on possible directions to further optimize the results. RESULTS: Several early phase studies demonstrated encouraging potential. However, translating preclinical outcomes to clinical settings proves challenging, especially in immunologically "cold" environments. GI cancers exhibit heterogeneity, requiring tailored approaches based on disease stage and patient characteristics. Current results, though promising, lack the power of evidence to influence the general practice. CONCLUSIONS: Finding biomarkers for identifying or converting resistant cancers is essential for maximizing responses, moreover in this context strategic RT parameters need to be carefully considered. Our review emphasizes the significance of having a thorough grasp of how immunology, tumour biology, and treatment settings interact in order to propose novel research avenues and efficient GI cancer therapy.

RÉSUMÉ

Hyperthermia, the raising of tumor temperature (≥39°C), holds great promise as an adjuvant treatment for cancer therapy. This review focuses on 2 key aspects of hyperthermia: its molecular and cellular effects and its impact on the immune system. Hyperthermia has profound effects on critical biological processes. Increased temperatures inhibit DNA repair enzymes, making cancer cells more sensitive to chemotherapy and radiation. Elevated temperatures also induce cell cycle arrest and trigger apoptotic pathways. Furthermore, hyperthermia modifies the expression of heat shock proteins, which play vital roles in cancer therapy, including enhancing immune responses. Hyperthermic treatments also have a significant impact on the body's immune response against tumors, potentially improving the efficacy of immune checkpoint inhibitors. Mild systemic hyperthermia (39°C-41°C) mimics fever, activating immune cells and raising metabolic rates. Intense heat above 50°C can release tumor antigens, enhancing immune reactions. Using photothermal nanoparticles for targeted heating and drug delivery can also modulate the immune response. Hyperthermia emerges as a cost-effective and well-tolerated adjuvant therapy when integrated with immunotherapy. This comprehensive review serves as a valuable resource for the selection of patient-specific treatments and the guidance of future experimental studies.

RÉSUMÉ

BACKGROUND: Extended pleurectomy decortication for complete macroscopic resection for pleural mesothelioma has never been evaluated in a randomised trial. The aim of this study was to compare outcomes after extended pleurectomy decortication plus chemotherapy versus chemotherapy alone. METHODS: MARS 2 was a phase 3, national, multicentre, open-label, parallel two-group, pragmatic, superiority randomised controlled trial conducted in the UK. The trial took place across 26 hospitals (21 recruiting only, one surgical only, and four recruiting and surgical). Following two cycles of chemotherapy, eligible participants with pleural mesothelioma were randomly assigned (1:1) to surgery and chemotherapy or chemotherapy alone using a secure web-based system. Individuals aged 16 years or older with resectable pleural mesothelioma and adequate organ and lung function were eligible for inclusion. Participants in the chemotherapy only group received two to four further cycles of chemotherapy, and participants in the surgery and chemotherapy group received pleurectomy decortication or extended pleurectomy decortication, followed by two to four further cycles of chemotherapy. It was not possible to mask allocation because the intervention was a major surgical procedure. The primary outcome was overall survival, defined as time from randomisation to death from any cause. Analyses were done on the intention-to-treat population for all outcomes, unless specified. This study is registered with ClinicalTrials.gov, NCT02040272, and is closed to new participants. FINDINGS: Between June 19, 2015, and Jan 21, 2021, of 1030 assessed for eligibility, 335 participants were randomly assigned (169 to surgery and chemotherapy, and 166 to chemotherapy alone). 291 (87%) participants were men and 44 (13%) women, and 288 (86%) were diagnosed with epithelioid mesothelioma. At a median follow-up of 22·4 months (IQR 11·3-30·8), median survival was shorter in the surgery and chemotherapy group (19·3 months [IQR 10·0-33·7]) than in the chemotherapy alone group (24·8 months [IQR 12·6-37·4]), and the difference in restricted mean survival time at 2 years was -1·9 months (95% CI -3·4 to -0·3, p=0·019). There were 318 serious adverse events (grade ≥3) in the surgery group and 169 in the chemotherapy group (incidence rate ratio 3·6 [95% CI 2·3 to 5·5], p<0·0001), with increased incidence of cardiac (30 vs 12; 3·01 [1·13 to 8·02]) and respiratory (84 vs 34; 2·62 [1·58 to 4·33]) disorders, infection (124 vs 53; 2·13 [1·36 to 3·33]), and additional surgical or medical procedures (15 vs eight; 2·41 [1·04 to 5·57]) in the surgery group. INTERPRETATION: Extended pleurectomy decortication was associated with worse survival to 2 years, and more serious adverse events for individuals with resectable pleural mesothelioma, compared with chemotherapy alone.
