Filter by:In elderly patients postoperative mortality measured 3-6 months after total mesorectal excision is high. Thus, less toxic treatments may lead to a survival benefit for elderly patients even if a risk of local recurrence is slightly higher compared to the open surgery. The investigators addressed the question whether watch and wait policy is safe in clinical complete responders after (chemo)radiation for elderly patients with small or moderately advanced tumours.
Concurrent chemotherapy with external beam radiotherapy is the standard treatment of bulky or locally advanced cervical cancer, gastric cancer and rectal cancer.Despite excellent therapeutic results, acute hematologic toxicity (HT) is common with this regimen. Previous studies have founded acute HT was significantly associated the volume of pelvic (PBM) and lumbosacral bone marrow (LSBM) receiving 10 and 20 Gy radiation (RT). Therefore, reducing the volume of BM receiving low-dose RT might prevent HT. More than one-half of the body's bone marrow (BM) is located in the PBM, LSBM and proximal, where is just in the low dose of RT in patients with gastric, rectal and cervical cancer. Previous study have demonstrated highly conformal IMRT treatment plans reduced the volume of PBM irradiated resulting in less HT. We have since assumed that even better BM sparing is possible when the BM is entered as a separate constraint in the planning process. However, it is well known that hematopoietically active (red) BM is poorly visualized with computed tomography (CT). Consequently, the entire contents of the medullary canals must be entered as BM. Yet, a considerable portion of the medullary canal is comprised of inactive (yellow) marrow, which is composed primarily of fat. Contouring the entire medullary canals on CT thus overestimates the volume of active BM, unnecessarily constraining the IMRT plan. An alternative approach is the incorporation of functional BM imaging into the treatment planning process. One economical and efficiency approach involves the use of T1-weighted magnetic resonance (MR) images. Therefore, we designed this study to test whether a separate constraint of active BM identified by MR could reduce acute HT in course of concurrent chemoradiotherapy for patients with gastric and rectal cancer.
This randomized clinical trial studies the Family Caregiver Palliative Care Intervention in supporting caregivers of patients with stage II-IV gastrointestinal, gynecologic, urologic and lung cancers. Education and telephone counseling may reduce stress and improve the well-being and quality of life of caregivers of cancer patients.
Erectile dysfunction will be explored by recording R / P and self-administered questionnaire IIEF-5.
The two surgical options for lower 1/3 rectal cancer is APR and sphincter sparing procedures. Intersphincteric resection is procedure to treat very low rectal cancer within 2 cm from the dentate line to avoid permanent colostomy,improves the quality of life with better genitourinary function. Neoadjuvant chemo-radiotherapy is routine for T3 cases.
The purpose of this study is to study which genes are abnormal in rectal cancer and see if this predicts how well chemotherapy and radiation will reduce the size of cancer and whether cancer recurs after surgery.
The purpose of this study is to see whether three new types of MRI techniques used during magnetic resonance imaging (MRI) of the pelvis to look at rectal cancer can help doctors to tell if the tumor is getting better in response to the radiation and/or chemotherapy treatments.
This pilot phase II studies how well computed tomography (CT) and positron emission tomography (PET) imaging works in detecting disease in patients undergoing surgery for metastatic colorectal cancer. Diagnostic procedures, such as CT and PET scans, done before and during surgery may help find colorectal cancer and help guide surgery
The purpose of this study is to establish a reliable method for detection of rectal cancer patients with aggressive tumor at risk of metastatic disease and death by functional MRI.
Clinical objective of the study is to compare the rates of pathologic response, acute toxicity and sphincter preservation with two schedules of preoperative regiment in patients with locally advanced rectal cancer.
