Clinical trials

Pediatric radiotherapy is an anxiety-provoking situation that can, on one hand, impair the child's cooperation and require sedation, and on the other hand,burden the care pathway by generating significant anxiety in both the child and their parents. Companion robots represent an innovative avenue for patient support, but they have never been evaluated in the context of radiotherapy. This study examines the effect of MIROKI, the first social robot capable of communication through a Large Multimodal Model (LMM), on children's state anxiety during radiotherapy. An experimental single-case design (SCED) will compare phases with and without the robot (withdrawal/reversal), both in the waiting room and in the irradiation bunker. The primary outcome variable is anxiety, assessed in several ways: through questionnaires at the beginning and end of treatment; through an objective measure of cardiac activity (heart rate in bpm) during the radiotherapy session, with or without the MIROKI robot; and through an observational grid assessing the child's behavior. The intensive repeated measure (bpm) constitutes the preferred variable in this SCED design, while behavioral observation and anxiety questionnaires will support interpretation. The results could pave the way for reducing sedation and improving the overall care pathway in pediatric radiotherapy.

Diffuse gliomas are among the most common tumors of the central nervous system, with high morbidity and mortality and very limited therapeutic possibilities. The diffuse glioma are characterized by significant variability in terms of age at diagnosis, histological and molecular features, classification, ability to transform to a higher grade and/or to disseminate in the brain, response to treatment and patient outcome. One of the main challenges in the management of diffuse gliomas is related to tumor heterogeneity within the same subgroup. Establishing an accurate tumor classification is of paramount importance for selecting personalized therapy or avoiding unnecessary treatment. At present, the main diagnostic methods for detecting gliomas are based on histopathological features and mutation detection. Yet difficulties remain, due to tumor heterogeneity and sampling bias for tumors obtained from small biopsies. In particular, grade 2 (low-grade) and grade 3 (high-grade) gliomas cannot be easily distinguished, as intra-tumoral tumor grade heterogeneity is not uncommon in patients treated with extensive surgical resection. Another challenge in the field of gliomas is longitudinal monitoring of disease progression, which is currently mainly based on repeated brain Magnetic Resonance Imaging (MRI). New tools to detect tumor changes before the onset of imaging changes would be useful. Several genetic, epigenetic, metabolic and immunological profiles have been established for gliomas. Recently, the world of RiboNucleic Acid (RNA) has emerged as a promising area to explore for cancer therapy, especially since the (re)discovery of RNA chemical modifications. To date, more than 150 types of post-transcriptional modifications have been reported on various RNA molecules. This complex landscape of chemical marks embodies a new, invisible code that governs the post-transcriptional fate of RNA: stability, splicing, storage, translation.

Each year in France, nearly 59,000 new cases of breast cancer are diagnosed, and approximately 22,000 mastectomies are performed. Among these patients, 30% choose to undergo breast reconstruction. Breast cancer leads to numerous physical and psychological changes. The need to strengthen patient support around breast reconstruction has been highlighted, and it is one of the priorities of the national Ten-Year Cancer Control Strategy. The growing number of patients living after cancer makes the management of post-treatment sequelae essential. The rate of reconstruction is increasing thanks to improvements in technique and better access to information. Among the available options, the latissimus dorsi (LD) flap has been a standard technique for immediate and delayed breast reconstruction for over 25 years. The LD technique offers several advantages: high reliability, feasibility even in irradiated thoraxes, low rates of postoperative complications, and satisfactory aesthetic outcomes. Its versatility and reliability have made it a cornerstone of breast surgery. However, this technique can lead to short- and long-term functional sequelae, which persist in 10% of patients. To reduce these side effects, an optimized version-the lipofilled mini-latissimus dorsi flap (mLD)-was developed by a team in Strasbourg. This quicker and less muscle-invasive technique is mainly used for immediate reconstruction or to replace implant-based reconstruction, with systematic lipofilling. However, no objective functional assessment of this method has yet been carried out, justifying a stratification according to the type of procedure for randomization in future studies. According to a prospective Icelandic study involving 15 patients, full recovery can be expected, but patients must be informed of the time and effort required to achieve it. The authors also concluded that further research is necessary to better understand the limits of long-term recovery. A study of 450 LD reconstructions showed that pain and the main functional sequelae were located in the back and shoulder, with 10% of patients experiencing significant long-term pain. In addition, according to this study, around 40% of patients consider postoperative sequelae and scarring burdensome. However, regret rates remain low, at under 3%. In view of these findings, preventing pain and functional impairment has become a key research focus to improve patients' quality of life. Postoperative rehabilitation plays a crucial role in managing pain, reducing functional impairment, and optimizing aesthetic outcomes. The addition of mechanostimulation (MS) has been shown to improve scar appearance, shoulder function, and functional well-being compared with rehabilitation alone. MS is delivered using a device equipped with motorized rollers and suction to mobilize tissues. In physiotherapy, it helps relieve pain and improve mobility. Prehabilitation, a rapidly expanding concept in surgery, aims to prepare patients before their procedure. However, to date, no prehabilitation approach combining physiotherapy and MS has been considered prior to LD flap surgery. One study highlighted improved tissue trophicity after tissue preparation with MS before lipomodelling. The objective of our study is to evaluate the benefit of prehabilitation through physiotherapy incorporating MS to prepare tissues (in particular skin and muscle) on shoulder pain and functional outcomes in patients undergoing breast reconstruction with a latissimus dorsi flap. Additionally, due to the heterogeneity and sometimes limited access to specialized postoperative physiotherapy, extensive patient follow-up has been planned in order to describe, on an exploratory basis, real-world rehabilitation practices.

Rectal cancer presents a significant global health challenge. Despite improvements in clinical outcomes, significant disparities persist across Europe. These differences are explained not only by the heterogeneity of risk factors and screening strategies, but also by variations in diagnostic and therapeutic approaches, which are highly dependent on medical imaging. Standard treatment for locally advanced rectal cancer based on staging MRI is neoadjuvant treatment (NAT), for tumour downsizing and downstaging, followed by total mesorectal excision. In a significant proportion of cases, radical surgery leads to substantial long-term complications like sexual and urinary dysfunction, fecal incontinence, and impairment in daily activities. Given that up to 42% of patients show complete tumor regression at pathology (i.e. pathological complete response pCR), to avoid unnecessary radical surgery, non-operative management has become an attractive alternative when there are no signs of viable tumour after NAT (i.e. clinical complete response cCR). Such patients are candidates for Watch-and-Wait (W\&W), an established active surveillance policy in specialized centers worldwide relying on clinical examination, endoscopy and MRI. On the other hand, W\&W carries a risk of local regrowth (persistence of microscopic residual disease despite apparent cCR). Even in expert hands, assessment of tumor response is not perfect and local regrowth based on current selection methods occurs in \~30% of cases. Although deferred surgery is a successful treatment with no apparent negative impact on local disease control, an increased rate of distant metastases has been recently reported. Therefore, there is a critical unmet clinical need to detect complete responses after NAT and avoid unnecessary surgery with its associated morbidity and quality of life impairment risks, while also improving sensitivity for residual microscopic disease that will result in local regrowth and associated reduced disease-free survival. Rectal cancer poses a burden not only on healthcare systems, but also on patient well-being. Patients frequently suffer from feelings of isolation and helplessness when faced with unpredicted disease-related situations, given the common difficulties to access high quality information and communicate with attending physicians. As such, there is a clear need to unburden healthcare facilities from unnecessary hospital visits, while improving patient outcomes, engagement, support and care.

Colorectal cancers and ovarian cancers are respectively the 2nd and 5th cause of cancer mortality in France. Surgical resection is a crucial step in the therapeutic management of colorectal cancers. For advanced ovarian cancers, the objective of cytoreductive surgery is to obtain complete macroscopic resection with no visible residual disease. One or more digestive resections are often required to achieve this goal of complete surgery (usually a modified posterior pelvic exenteration with colorectal resection). A ligation of the inferior mesenteric artery at its origin is classically performed in left colectomies and rectal resection for colorectal cancers. This allows the resection of the colorectal segment with a complete mesocolic lymphadenectomy until the origin of the inferior mesenteric artery and a good mobilization of the descending colon to allow its anastomosis to the underlying rectal stump. This ligation of the inferior mesenteric artery at its origin is also frequently performed in cases of modified posterior pelvic exenteration for ovarian cancer. Recently, several studies suggest that arterial ligation of the inferior mesenteric artery could be performed below the emergence of the left colic artery. Its preservation requiring a meticulous vascular dissection would allow a better vascularization of the descending colon and of the colorectal anastomosis without affecting the carcinologic quality of the resection and the number of resected lymph-nodes. Indeed, the most feared complication during colorectal anastomosis is the anastomotic leakage whose rates are on average 15% in rectal cancer with low anastomosis and 6% in ovarian cancers. Verifying the adequate vascularization of the descending colon before performing the colorectal anastomosis is a crucial step in reducing the risk of postoperative fistula. However, quantifying this vascularization is challenging, and several techniques can be used to assess it. The gold standard technique involves measuring arterial pressure using a catheter inserted into the marginal artery of the descending colon. Other non-invasive techniques also use Doppler studies to calculate pressure in the marginal artery or assess oxygen saturation using a sterile sensor. Studies have shown that the use of indocyanine green in colorectal surgery, particularly to evaluate perfusion before the creation of an anastomosis, significantly reduces the rate of anastomotic leakage. Indocyanine green is a fluorescent dye that, after intravenous injection, binds to plasma proteins and allows tissue perfusion to be visualized using a fluorescence system. The objective of this project is to show that the preservation of the left colic artery is possible and allows a better vascularization of the descending colon before colorectal anastomosis.

Chemotherapy-induced peripheral neuropathy (CIPN) (including taxanes, platinum, al pervenche from Madagascar alkaloids...), is a frequent secondary effect of treatments: 68% at 1-month post-chemotherapy, 60% at 3 months and 30% after 6 months. Symptoms associated with CIPN are usually symmetric and bilateral (typical distribution in "gloves and socks") inducing sensory alterations, paresthesias, dysesthesias, numbness and pain. Neuropathic Pain (NP) is an important characteristic of CIPN, affects 25-80% of patients with CIPN, and reduces quality of life (e.g., concomitant psychological distress, risks of falls, risks of neurocognitive impairments, and sleep disorders). In severe cases, it is even necessary to delay and/or reduce the dose of chemotherapy. The benefit of drug interventions on NP remains limited. To date, there are no proven preventive strategies and few evidence-based treatment options for CIPN. Also, the use of complementary or non-pharmacological interventions are common, including photobiomodulation (PBM). PBM is the therapeutic use of non-ionizing laser light for its anti-inflammatory and regenerative effects. Its use is currently recommended only for the prevention of oral mucositis related to cancer treatments. Recent preliminary clinical evidence suggests that PBM may be beneficial to established CIPN, with safety and improvement beyond the intervention. However, to date, clinical trials are rare, have methodological weaknesses, and/or focus on global CIPN. The overall objectives of the study are therefore to assess the effectiveness, feasibility and safety of the PBM for treating NP in the CIPN.

In France, since the reimbursement of Lutathera®, this treatment is allowed for retreatment if patients still fulfill the criteria of its indication and 4 news cycles could be proposed. However, clinical practices are heterogeneous regarding the number of new cycles and most teams perform only two additional cycles (every 8 weeks). Therefore, the coordinator propose to evaluate the efficacy of two additional cycle of Lutathera® versus active surveillance in patients already retreated with two cycles Lutathera® for a new progression of intestinal neuroendocrine tumor and who previously received the 4 cycles of treatment with a clinical benefit.

As much as 50% of patients treated with hormonotherapy (HT) for breast cancer (BC) suffer from osteoarticular pain during treatment. Secondary effects have become a real issue because of their consequences on the patients' quality of life, but also on treatment efficacy and survival when they induce dose reduction or premature withdrawal of treatment. Additional medicines (acupuncture, hypnosis, yoga) have become more and more popular these last years. 48 to 80% of patients with BC eventually choose them. A review comparing efficacy of various therapies to decrease osteoarticular pain concludes to a highest efficacy of anti-inflammatory treatments, paracetamol and yoga. It thus appears innovative to complete this care with a patient educational project (PEP) in postural yoga instructed by a trained physical therapist, which will enable patients to practice yoga postures at home by themselves. The investigators conducted a pilot study "SKYPE" with 24 algic patients treated with HT after BC, whose results are very promising. The investigators now propose in the continuity of the pilot study a multicenter randomized controlled study comparing the efficacy of SKYPE care on pain reduction, an educative care combining physical therapy and yoga, to a control group in patients treated with HT for a BC with osteoarticular and/or musculoskeletal pain. Furthermore, in order to examine whether yoga interventions may influence inflammation through their effects on the level of a wide range of pro- and anti-inflammatory cytokines (30), the investigators will Change in circulating cytokines' level between baseline level (T0) and post-treatment level (T2) in both groups will be analyzed and if so correlation will be established.

Development of a clinico-biological database allowing the provision of clinical data and corresponding biological materials to the medical and scientific community.

The aim of this study is to evaluate the efficacy of sequential treatment (Gabrinox) comprising Gembrax regimen (Gemcitabine -Abraxane) followed by the Folfirinox regimen (5FU, Oxaliplatin and Irinotecan) compared to folfirinox alone in patients treated in first metastatic line pancreatic cancer

This study evaluates the capacity of the NovaGray RILA Breast® test to predict the toxicity linked to radiotherapy and the impact of implant breast reconstruction.

In patients with cancer associated with human papillomavirus (HPV), the physical effects of treatment, combined with the psychosexual impact linked to HPV status, can further impair the quality of sexual life. However, few studies have examined the specific effect of HPV status (or knowledge of status) on the recovery/quality of sexuality following radiotherapy. It is against this backdrop that we propose a prospective longitudinal study specifically dedicated to investigating the sexual quality of life of women with HPV-positive pelvic cancer. This type of study will enable better quantification and description of sexual dysfunction occurring after treatment, and assessment of the impact of HPV carriage, with the future aim of guiding new prevention and management strategies.

The innovative nature of this project lies in the combination of three types of intervention: tobacco addiction treatment, music therapy and therapeutic education. Three disciplines that work together. 1. Tobacco addiction treatment: reducing consumption, quitting, 2. Music therapy: acting on emotions and reward circuits, 3. Therapeutic education: promoting independent healthy practices. Patients learn to use the soundtrack independently to help them manage withdrawal symptoms caused by reducing or stopping tobacco consumption. In this programme, patients play an active role on several levels: * working with the music therapist to create a personalised 'soundtrack'; * identifying situations in which music can help them manage withdrawal symptoms; * using music independently in their everyday lives. The music therapy protocol will be proposed in this study, the soundtrack is co-created by the music therapist and the patient based on the patient's musical tastes and needs. The fact that the patient can use the musical tool independently also gives them significant leverage in their withdrawal process, allowing them to act on withdrawal symptoms and the main factors contributing to relapse.

Oncogeriatric: a collaboration between oncologists and geriatricians which aims to ensure that all elderly cancer patients receive treatment adapted to their condition, thanks to a multidisciplinary and multi-professional approach. This project aims to gain a better understanding of the motivational determinants of PA and nutrition in elderly cancer patients. It has a dual objective: 1. to identify clusters/groups in patients on the basis of daily motivational factors focusing on PA and nutrition 2. on the basis of the results obtained in (1), to propose an interventional study based on the previously established clusters, in order to examine the effects of a behavioral intervention on patients' adherence to PA and nutrition, both agreed according to an individualized goal and defined in agreement with the patient and the multidisciplinary team, taking into account the recommendations.

Our objective is based on a personalized approach of adjuvant breast radiotherapy by selecting patients according to tumor recurrence and toxicity risk.

Pulmonary tumors, whether primary or metastatic, represent a major challenge in oncology. Primary lung cancers are responsible for nearly 37,000 deaths per year in France, highlighting the critical importance of their management. Moreover, secondary pulmonary lesions are present in 20% of solid cancers and show wide variability in prognosis. Oligometastatic disease (≤ 3 to 5 lesions) is associated with a better prognosis, justifying the development of local treatments for these lesions, particularly stereotactic radiotherapy. During the COVID-19 pandemic, single-fraction protocols (30-34 Gy) were implemented to limit patient exposure, showing outcomes equivalent to multi-fraction regimens for both primary and secondary lesions. However, the impact of these treatments on quality of life remains poorly documented-especially for non-small cell lung carcinoma-and needs to be further explored to optimize their integration into routine clinical practice. The primary objective of this study is to assess the impact of single-fraction stereotactic body radiotherapy (SBRT) for pulmonary lesions on quality of life. To this end, patients will complete a standardized French-language quality of life questionnaire, the EORTC QLQ-C30 and LC-29, before treatment and at 1 month (M1), 3 months (M3), 6 months (M6), 9 months (M9), and 12 months (M12) after treatment. This validated, disease-specific questionnaire comprises 59 items: 30 assessing overall quality of life (QLQ-C30) and 29 addressing aspects related to lung cancer treatments (LC-29). It includes questions on respiratory symptoms, chest pain, fatigue, and the functional impact of the treatment.

There is little scientific data concerning the use of negative pressure therapy after immediate breast reconstruction. That strategy of treatment-reconstruction has expanded increasingly since the last years. The current literature reports only 3 studies on the use of preventive negative pressure therapy in oncologic breast surgery. Moreover, all three are retrospective, case-control studies with serious limitations. The largest published series reports a reduction in the overall complication rate from 15.9% to 8.5%, and a significant reduction in several criteria: infection, scar dehiscence and necrosis. However, the study presents significant biases, with non-comparable populations in terms of comorbidities, surgical procedure performed, inclusion periods (and therefore experience in performing oncological surgery). There was also a high probability of under-assessment or postponement of post-operative complications, which is typical of published retrospective surgical studies. The published results therefore strongly encourage further investigation of negative pressure therapy in oncological breast surgery.

Locally advanced rectal carcinoma raise the issue of both the oncological control, local and general, and the therapeutic morbidity. Surgery alone can cure only one out of two patients, radiochemotherapy improves the local control but the metastatic risk remains about 30% with enhanced postoperative morbidity and poor functional results. The tumor response to preoperative treatment is the major prognostic factor which revealed the aggressiveness of the tumor. To this day, there are no biologic predictive markers for tumor response. The purpose of this trial is to tailor the management according to the early tumoral response after short and intensive induction chemotherapy. MRI volumetric tumor response will be used to distinguish between good responders and bad responders. "Very good" responders will be randomized to either immediate surgery or radiochemotherapy followed by surgery (Standard arm: Cap 50).

to analyze the feasibility for patients with early luminal breast cancer to be compliant with a diet modification - ketogenic or proteins restricted diet - during 9 +/- 1 days, before breast cancer surgery. It's a Pilot study, monocentric, randomized

The investigator proposes to use the cardiac coherence technique to diminish anxiety before the surgery of a peritoneal carcinosis of colon or stomach or ovary and pseudomyxoma or peritoneal mesothelioma.

Trimodal therapy (TMT) consisting of transurethral resection of bladder tumors followed by radiotherapy and chemotherapy is a therapeutic alternative in patients with Muscle-Infiltrating Bladder Cancer who are inoperable or refuse surgery. One of the main challenges of TMT is the planning and delivery of radiation therapy. Indeed, the bladder is a mobile hollow organ subject to repletion, with variations in size and shape during and between radiotherapy sessions. Standard radiotherapy techniques require large planning target volume margins around the bladder, which can be responsible for irradiation of a large volume of large and small bowel with grade 2 and 3 toxicities. Adaptive radiotherapy allows for the generation of a treatment fraction personalized to a patient's anatomical modification with margin reduction and improves the dosimetric quality of the delivered plans. The hypothesis is that this improvement results in radiation-induced toxicity improvement.

Diffuse low-grade glioma are rare brain tumors affecting young subjects (median age at diagnosis 38 years for grade 2 and 49 years for grade 3). Cognitive symptoms are common in these patients, including memory, attention and executive function disorders. These disorders may have a deleterious impact on patients' professional, family and social lives, and have a negative impact on their quality of life. The benefits of cognitive rehabilitation have been demonstrated in other neurological pathologies. Furthermore, due to limited access to rehabilitation by neuropsychologists, some studies have evaluated the impact of digital cognitive rehabilitation programs. However, it cannot replace human support.

The aim of this study is to demonstrate the efficacy of intensified and sequential chemotherapy (Gabrinox) comprising Gembrax regimen (Gemcitabine-Abraxane) followed by the Folfirinox regimen (5FU, Oxaliplatin and Irinotecan) in patients with locally advanced pancreatic adenocarcinoma. The study will also demonstrate the feasibility of combining this intensified chemotherapy with MRI-guided stereotactic radiotherapy in non-progressive patients after the chemotherapy by Gabrinox regimen.

The treatment of breast cancer as well as the disease are responsible for genito-urinary symptoms that can persist over time and impair quality of life. Given the improved prognosis of breast cancer, more and more patients are confronted with specific post-cancer issues, and the care has become a major health challenge. Sexual health is a crucial component of well-being and overall quality of life. Vaginal dryness and dyspareunia are symptoms frequently found in patients treated for breast cancer, with chemotherapy and hormone therapy as risk factors. However, the treatment of sexual disorders remains underdeveloped in France. Vaginal dryness is part of a broader syndrome known as genitourinary syndrome of menopause (GSM), or vulvovaginal atrophy, which may combine vulvovaginal (dryness, irritation, burning), sexual (dyspareunia) and urinary (infections, pollakiuria, urgency) symptoms secondary to hypoestrogenemia, exacerbated by breast cancer treatments. Since hormonal treatments are contraindicated, the first-line treatment for GSM in patients treated for breast cancer is the application of non-hormonal trophic treatments (regular vaginal moisturizers, lubricants during intercourse). However, these treatments are often insufficient to provide effective relief. There is therefore growing interest in the development of second-line treatments for GSM : intra-vaginal hyaluronic acid injections, laser, photobiomodulation (PBM), etc. PBM using Light Emitting Diodes (LED) has been proposed as an alternative treatment for genitourinary syndrome of the menopause. The tissues are exposed to light sources in the visible spectrum, inducing non-thermal, non-cytotoxic biological effects that improve vaginal tissue trophicity. In line with previous studies of sexual quality of life carried out at the center, and in the context of the recent establishment of our multidisciplinary network for the 2nd-line treatment of genitourinary menopausal syndrome with Photobiomodulation, we would like to carry out a descriptive study of the sexual QoL of patients undergoing treatment for breast cancer and benefiting from this oncosexological support.
