Filter by:Patients diagnosed with locally advanced very low rectal cancer were chosen to participate in a comprehensive neoadjuvant therapy (TNT) protocol. This treatment regimen consisted of preoperative fractionated radiotherapy (5×7Gy) combined with 6 cycles of CAPOX chemotherapy and enverolimab. For patients who achieved clinical complete response (cCR) or near-clinical complete response (ncCR) after undergoing TNT, an organ-preserving strategy involving local full-thickness resection was implemented.
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.
Patients with locally advanced non-metastatic adenocarcinoma of the rectum undergoing chemoradiation therapy will be assigned to 2 groups: - the intervention group will be prescribed an individualized ketogenic eating plan to be followed throughout the treatment period - the control group will be prescribed a diet therapy plan treatment following the international guidelines of clinical nutrition, also to be followed during treatment
RectSexQoL is a study aiming at determining the prevalence of female sexual dysfunction after rectal cancer surgery. It has the goal as well to analyse the impact of an intervention given by a sexologist to such patients.
Rectal cancer is one of the most prevalent malignancies in the world, and its prevalence is rising. In more advanced cases neoadjuvant therapy is advised before to surgery, and radiotherapy is one of its cornerstones. For the treatment of rectal cancer, there are primarily two radiation techniques. Long-term radiotherapy is 50.4 Gy delivered in 28 fractions, while short-term radiotherapy is 25 Gy delivered in 5 parts. In earlier studies, these two radiation techniques were combined with various chemotherapy drugs, and a relative comparison was established. Total neoadjuvant treatment, or TNT, has been linked to a better outcome because of the significance of organ preservation. The aim of this research is to compare two TNT radiation techniques with the same regimen of treatment.
In the present study, the investigators will evaluate the efficacy, toxicities, and of online adaptive radiation therapy (ART) for patients with rectal cancer treated with neoadjuvant chemoradiotherapy.
The primary objective of this research study is to explore the barriers encountered by specific demographic groups of rectal cancer patients during the engagement in clinical trials, which historically lack diverse representation. By carefully analyzing data from various demographic perspectives, this study aims to uncover patterns that impact the experiences of future rectal cancer patients. Active involvement in this crucial research is of utmost importance, as it can offer unique insights to enhance the participation and completion rates of rectal cancer patients in clinical study.
Rectal cancer is one of the most common malignant tumors, with 9% to 23% of patients experiencing pelvic sidewall lymph node metastasis. According to the current Chinese guidelines for diagnosing and treating colorectal cancer, pelvic sidewall lymph node dissection is recommended for patients who have experienced or are suspected of having lateral lymph node metastasis. Lateral lymph node dissection can result in longer operation times, increased bleeding, and complications such as urinary and sexual dysfunction after surgery. Currently, the presence of metastasis is primarily determined by the size and enhancement characteristics of lateral lymph nodes observed through imaging studies. However, the pathological lymph node metastasis rate of specimens collected after lateral lymph node dissection based on current imaging criteria is only 20.5%. Therefore, a pressing clinical challenge is accurately determining the presence of lateral lymph node metastasis and avoiding unnecessary lateral lymph node dissection in patients who have not experienced lateral lymph node metastasis. Sentinel lymph node biopsy has been widely used in clinical practice. It has replaced traditional lymph node dissection in some breast cancer and melanoma patients, reducing surgical risks and complications and improving patients' quality of life. This study aims to use indocyanine green as a tracer for fluorescence-guided laparoscopic navigation to locate the lateral sentinel lymph nodes of rectal cancer in the pelvic cavity. By studying the accuracy, specificity, and false-negative rate of predicting lateral lymph node status using the sentinel lymph node, we can further clarify the clinical significance of the lateral sentinel lymph node.
Prospective phase II clinical study aim to explore the clinical outcome of patients with unresectable locally recurrent rectal cancer (LRRC) treated with re-irradiation by carbon ion radiotherapy (CIRT)
