Filter by:The goal of this prospective phase II study was to determine whether personalized planning-based nCRT for LARC would indeed decrease small bowel dose, and whether selected plans, specifically prioritizing lower dose to small bowel, would result in lower rates of acute GI toxicity compared with previously reported rates.
In previous studies, the investigators found that five factors were effective in predicting the probability of locally advanced cervical cancer with para-aortic lymph node metastasis.A retrospective study was conducted to explore the influence of 5 factors on PFS in patients with locally advanced cervical cancer receiving radiotherapy and chemotherapy.
To determine whether older patients who underwent esophagectomy had better outcome survival than those who were non-surgically treated.
To evaluate the intervention effect of triple pre-rehabilitation on head and neck cancer patients with radiotherapy, and process evaluation to further optimize the intervention program. The pre-rehabilitation intervention was develped previously based on the process of evidence-based-nursing, including interventions of nurtrtion, exercise, and psychology.
The treatment guideline for locally advanced resectable oral squamous cell carcinoma (LAROSCC) is surgery + postoperative radiotherapy/chemoradiotherapy. Though the treatment is intensive with serious harm to quality of life, the survival of patients is poor. Neoadjuvant therapy has been evaluated in a number of clinical trials for LAROSCC, but failed to directly improve the overall survival. On the other hand, de-escalation of treatment followed by neoadjuvant is also been explored with some promising results. This study is to retrospectively include patients with LAROSCC who received neoadjuvant therapy and surgery. Survival between patients in two cohorts (cohort 1: received postoperative radiotherapy, cohort 2: received no postoperative radiotherapy) are to be compared.
Bowel dysfunction is common after a restorative rectal cancer resection. Neoadjuvant radiotherapy is an influential factor that impairs bowel function and quality of life. However, almost half patients who have received primary surgery with preoperative radiotherapy are able to restore a good or moderate bowel function in the long term. This multicenter observational study aims to identify the risk factors of severe bowel dysfunction after rectal cancer resection and neoadjuvant radiotherapy, in accordance with the LARS score, and to build a model that predicts long-term major LARS in the early stage of follow-up. Development and validation cohorts are enrolled from tertiary hospitals in China.
The aim of the study is to evaluate whether the preoperative level of myeloid-derived suppressor cells is associated with postoperative complications classified by Clavien-Dindo categories. Levels of all MDSC, polymorphonuclear MDSC (PMNMDSC), monocytic MDSC (MMDSC), early-stage MDSC (EMDSC) and monocytic to polymorphonuclear MDSC ratio (M/PMN MDCS) were established and compared in patients with postoperative complications, severe postoperative complications (>= IIIA according to Clavien-Dindo) and severe septic complications.
Bone marrow is one of the organs at risk of complications during irradiation due to its radiosensitivity. Hematopoietic toxicity remains one of the main toxicities during irradiation of pelvic lymph node areas, especially when concomitant chemotherapy is used, volume of bone marrow irradiated is large and dose to the bone marrow is high. There is a lack of prospective studies and comparative trials to customize the constraints according to the presence or absence of chemotherapy and correlated to the patient's bone marrow potential. This multicentric and prospective study conducted by Strasbourg Europe Cancerology Institute aims to evaluate hematological toxicity (anemia, thrombocytopenia, leukopenia) in patients treated with pelvic irradiation for prostate, rectum, anal canal, endometrium, cervix cancer or vaginal cancer. One hundred patients will be included in the study, including patients treated with exclusive radiotherapy, radiochemotherapy, or radiohormonal therapy. The primary objective is to quantify the relationship between acute hematological toxicity and delivered doses and irradiated volumes in pelvic bone marrow for pelvic cancers. Hematological toxicity will be measured by weekly blood count during radiotherapy and at one month and three months after the end of radiotherapy. Secondary endpoints are the evaluation of viral, bacterial and fungal infections during and for three months following radiotherapy, as well as the evaluation of the impact of radiation-induced hematological toxicity on the administration of chemotherapy for the concerned patients. The aim of this study is to improve and optimize radiotherapy if a dose limit or volume constraint is imposed by the results of the study.
Prostate cancer (PCa) is among the most widespread in the male population and represents 19% of all cancers diagnosed from the age of fifty, in Italy. Androgen deprivation therapy (ADT) and Radiotherapy (RT) are used for increase survival. However, both therapies are associated with significant side effects, such as fatigue, loss of muscle mass and strength, cognitive decline that together lead to an increase risk of accidental falls and fractures. Guidelines for cancer survivors recommend Physical Exercise (PE) as a strategy to reduce several side effects of therapies. However, most people living with cancer do not meet current exercise recommendations. Indeed, an effective PE program requires the application of long-term, moderate to high intensity activity. Thus it may be difficult to implement this type of recommendation in patient with PCa. Therefore, this study aims to develop an experimental PE intervention testing their feasibility and safety and the patients' satisfaction, aimed at improving the health conditions of the patients with PCa receiving ADT and RT. Furthermore, long-term falls and fracture events will be monitored.
This project's goal is to develop and test an application that uses Artificial Intelligence (AI) to improve consistency and quality of Radiation Treatment (RT) plans for prostate cancer. By understanding expert planner preferences in structure contouring and treatment planning, and combining this framework with planning data and outcomes amassed in NRG clinical trials, AI models may be trained to produce contours and treatment plans that are indistinguishable or even potentially deemed superior to those produced by individual experts. At the conclusion of this contract, the awardees will provide a software product which, when given the input of a description of desired anatomical target volumes and target doses along with a patient's CT scans, will generate target volumes and radiation treatment plans based upon a "gold standard" amalgamated from the input of multiple experts, thereby achieving desired doses to target volumes while meeting or exceeding the dose-volume constraints imposed by adjacent normal tissues.
