SCRT Sequential Penpulimab in Combination With CAPEOX in the Neoadjuvant Treatment of MSS Locally...

Rectal CancerLocally Advanced

The goal of this phase 2 study is to learn about the efficacy and safety of short-course radiotherapy (SCRT) sequential Penpulimab in combination with CAPEOX in the neoadjuvant treatment of microsatellite stable (MSS) locally advanced rectal cancer. The main question it aims to answer is the role of immune checkpoint inhibitors in the neoadjuvant treatment of MSS rectal cancer. Participants will receive neoadjuvant treatment of SCRT sequential Penpulimab in combination with CAPEOX. Participants will undergo a clinical re-staging assessment at the end of neoadjuvant therapy to determine whether to adopt a watch-and-wait strategy or undergo radical surgery.

The Clinical Efficacy of Drug Sensitive Neoadjuvant Chemotherapy Based on Organoid Versus Traditional...

Neoadjuvant Therapy

This is a prospective multicenter randomized controlled trial study. According to the enrollment criteria, patients with locally advanced rectal cancer who need neoadjuvant therapy before radical surgery were randomly divided into the organoids drug sensitivity group and the standard whole-course neoadjuvant therapy group. The Organoids drug sensitivity group was treated with personalized neoadjuvant therapy under the guidance of tumor organoids drug sensitivity technology combined with standard long-term radiotherapy. The standard whole-course neoadjuvant therapy group was treated with neoadjuvant simultaneous radiotherapy and chemotherapy (Total Neoadjuvant Therapy, TNT) based on guidelines and clinical experience. The tumor pathological complete remission rate (pCR), postoperative complication rate, postoperative tumor withdrawal grade, postoperative recurrence rate, treatment tolerance rate, R0 resection rate, and sphincter preservation rate were observed and compared.

Neoadjuvant Chemoradiotherapy Versus Total Neoadjuvant Therapy in the Treatment of T3 Rectal Cancer...

Rectal Cancer

The gold standard treatment for locally advanced, non-metastatic rectal cancer includes neoadjuvant chemoradiotherapy (NACRT), total mesorectal excision (TME) and adjuvant chemotherapy (AC). The primary goal of treatment is to achieve local disease control, reduce tumour volume and minimise the risk of distant metastases. While this multimodal treatment approach has offered improvements in local control and sphincter preservation, it has had little effect on distant recurrence and overall survival. We aim to compare NACRT and TME using the following endpoints: Primary -->To compare the effects neoadjuvant chemoradiotherapy versus total neoadjuvant therapy (TNT) for T3 rectal cancer on overall survival. Secondary --> To compare the effects neoadjuvant chemoradiotherapy (NARCT) and total neoadjuvant therapy (TNT) for cT3 rectal cancer on clinical outcomes: Clinical complete response (cCR) Pathological complete response (pCR) Disease-free survival (DFS) Organ preservation Overall morbidity / mortality Treatment-related morbidity / mortality Peri-operative outcomes

Performance of Spectral CT-scan in Patients With Metastatic Colorectal Cancer: a Prospective Multicentre...

Colo-rectal Cancer

Spectral CT is a rapidly expanding imaging modality that allows a reduction in iodine dose and irradiation compared to conventional scanning. It uses the difference in attenuation of the material according to the two different energy levels of the incident x-ray beams. The dual-energy scanner has a wide range of clinical applications, particularly in abdominal imaging.

Treating Locally Advanced Rectal Cancer With TAS-102 Chemotherapy Plus Neoadjuvant Radiotherapy...

Rectal Cancer

The goal of this Phase 2 trial is to evaluate a neoadjuvant treatment mode for locally advanced rectal cancer (LARC), consisting of radiotherapy and concurrent Trifluridine/Tipiracil (TAS-102). The main questions it aims to answer are: (i) whether TAS-102 is effective in treating LARC, when combined with radiotherapy; (ii) whether TAS-102 is safe in combination with radiotherapy. Participants will receive one cycle of TAS-102 chemotherapy and neoadjuvant radiotherapy based on intensity-modulated technique. Then the ones with a possibility of R0 resection will receive radical surgery followed by 6 cycles of adjuvant XELOX (capecitabine plus oxaliplatin) chemotherapy.

Targeted Therapy Directed by Genetic Testing in Treating Patients With Advanced Refractory Solid...

Advanced Malignant Solid NeoplasmBladder Carcinoma48 more

This phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

Validation of the French Version of the Low Anterior Resection Syndrome (LARS) Among Rectal Cancer...

Rectal Cancer Patients

Oncological rectal cancer outcomes have improved considerably because of optimal surgery by total mesorectal excision in conjunction with multidisciplinary team management by selective multimodal therapy (ie, neo-adjuvant chemo-radiotherapy). The 5-year survival has increased to more than 50% and local recurrence has been reduced to less than 10%. These advancements have resulted in more patient receiving sphincter-preserving surgery (SPS). With an increasing number of rectal cancer survivors, the investigators observe a rising attention to the disordered bowel function after SPS, called "low anterior resection syndrome" (LARS). LARS appear immediately after surgery, becoming most pronounced during the first few months, and improved thereafter, reaching a steady state after around two years. However, up to 60% of patients with SPS suffer from LARS which impaired their quality of life (QoL). The prevalence and severity of LARS is difficult to assess due to heterogeneity of the assessment tools. A group of Danish authors have recently developed and validated a five-item instruments for evaluation of LARS (LARS score). It represents to date the best questionnaire to capture anorectal postoperative function and consists of five items: incontinence for flatus, incontinence for liquid stool, frequency of bowel movements, clustering of stools, and urgency. It allows a categorization of patients into 3 groups: no LARS (0-20 points), minor LARS (21-29 points), and major LARS (30-42 points). Developed in Danish, it is now internationally validated with translations in Chinese, English, German, Spanish and Swedish. To our knowledge, French version of the LARS score is not yet available. The aim of our study will be to adapt the LARS scale questionnaire to the French language (LARS-F), and assess its psychometric properties. Inclusion criteria will be patients 18 years old or above who were operated for rectal cancer from 2007 to 2015. Exclusion criteria will include the presence of stoma and/or known disseminated or recurrent disease. Patients will be identified through local databases by the local investigators at each of the participating centers with a minimum duration of 24 months after surgery to allow their bowel function to have regained stability. This study will be supported by the French Research Group of Rectal Cancer Surgery in order to allow the feasibility of the project. After translation/back-translation procedures in accordance with the permission from the original authors, the LARS-F score and the whole translation process will be then sent to the original authors for approval. Then a pilot study will be conducted. The French questionnaire (LARS-F score) will be then administered to 100 patients in order to verify the adequacy and degree of comprehension of the questions. Reproducibility will be investigated by a test-retest procedure. A randomly selected subgroup of participants (n= 400) will be sent the LARS-F score questionnaire twice (with an interval of two weeks). The test-retest reliability of the questionnaire will be assessed by the Cohen's Kappa (no, minor and major LARS scores) or by intra-class correlation coefficient, ICC (quantitative LARS score). Then, eligible patients will receive a postal invitation to complete the LARS-F score and the l'European Organization for Research and treatment of Cancer (EORTC) QLQ-C30 and QLQ-CR29, respectively. The validity of the LARS-F score will be tested by using the indicators of convergent validity and discriminant validity. The convergent validity will be determined notably in this study by computing the correlations between the LARS-F score and the EORTC QLQ-C30 and QLQ-CR29 domains. For discriminant validity testing, the investigators will use known variables to affect bowel function after SPS, such as gender, age, neo-adjuvant radiation therapy, distance of the tumor from the anal verge, prior temporary stoma, and length of postoperative period. The validation of the French version of the LARS score will allow to use a scientific instrument in order to assess both prevalence and severity of LARS. This instrument will allow to develop a future research and clinical practice in France. It will be used in the daily clinical practice to identify patients with LARS score. It will hopefully lead to improve the awareness of clinicians, in order to improve the prevention and the treatment of bowel dysfunction, as well as the information given to patients. In the future, the investigators will able to develop a new patient-led follow-up program based on symptom burden and health-related QoL.
