Filter by:To compare the pathological effect between 2 cycles and 4 cycles of Capox regimen as neoadjuvant chemotherapy for low/ intermediate risk stage II/III rectal cancer.
In patient with complete pathological response, surgery could be omitted without compromising progression-free or overall survival. A powerful prediction model is needed to guide management of this population. Radiomics features provide complementary information about tumor heterogenity. The aim of the investigators is to develop a model combining clinical and radiomic criteria able to predict complete pathological response.
Background The current management on rectal cancer based on TNM staging has some limitations. In locally advanced rectal cancer after neoadjuvant therapy the persistence of a complete response to therapy cannot be accurately predicted by the simple tumor regression grade. The current guidelines recommend the complete rectal resection with a total mesorectal excision. The implications for patients' quality of life are evident even in case of sphincter sparing surgery. Moreover, in both cases the cancer sample available for the analysis can be small or inexistent. Hypothesis The main hypothesis underlying our research is that the aggressiveness of rectal cancer is determined by the complex interactions between the malignant cells and their immune microenvironment. The second hypothesis is that relevant trace of this cross talk between tumor cells and immune microenvironment can be detected in the normal mucosa surrounding the cancer according to the concept of field cancerization. Aims The aim of this project is to analyze the healthy rectal mucosa surrounding the cancer to identify traces of immunosurveillance mechanisms and of field cancerization and to use them to obtain a composite prognostic test to predict recurrence after complete response at neoadjuvant therapy in case of locally advanced rectal cancer. Experimental Design This prognostic test will be constructed on the combinatory analysis of the transcriptome, immune and epithelial cells cross-talk, immune checkpoints and miRNA expression in normal rectal mucosa surrounding cancer. The project aim is to identify, among locally advanced rectal cancer, those with sustained complete response to neoadjuvant chemo/radiotherapy. The study is articulated in two steps. In step A, we will retrospectively analyze archival tissue samples in order to identify the most performing biomarkers; in step B, we will validate the prognostic performance of the markers identified in phase I through a prospective analysis of rectal mucosa specimen.
This study will assess if the CARES (Cancer Advocacy, Resources, Education and Support) intervention improves time to start of treatment after diagnosis and time to treatment completion for solid tumors (ex: lung, head, neck, thyroid, cervical, breast, bladder, colon, and rectal cancers) in rural patients.
ABSTRACT Background The current management on rectal cancer based on TNM staging has some limitations. In early rectal cancer T stage can be not sufficient to predict the nodal status and, in locally advanced rectal cancer after neoadjuvant therapy the persistence of a complete response to therapy cannot be accurately predicted by the simple tumor regression grade. For both cases the current guidelines recommend the complete rectal resection with a total mesorectal excision. The implications for patients' quality of life are evident even in case of sphincter sparing surgery. Moreover, in both cases the cancer sample available for the analysis can be small or inexistent. Hypothesis The main hypothesis underlying our research is that the aggressiveness of rectal cancer is determined by the complex interactions between the malignant cells and their immune microenvironment. The second hypothesis is that relevant trace of this cross talk between tumor cells and immune microenvironment can be detected in the normal mucosa surrounding the cancer according to the concept of field cancerization. Aims The aim of this project is to analyze the healthy rectal mucosa surrounding the cancer to identify traces of immunosurveillance mechanisms and of field cancerization and to use them to obtain a composite prognostic test to predict nodal metastasis in early rectal cancer and recurrence after complete response at neoadjuvant therapy in case of locally advanced rectal cancer. Experimental Design This prognostic test will be constructed on the combinatory analysis of the transcriptome, immune and epithelial cells cross-talk, immune checkpoints and miRNA expression in normal rectal mucosa surrounding cancer. The aim is to predict the presence of nodal metastasis in patients with early rectal cancer. In step A, we will retrospectively analyze archival tissue samples in order to identify the most performing biomarkers; in step B, we will validate the prognostic performance of the markers identified in phase I through a prospective analysis of rectal mucosa specimen. Expected Results The anticipated outcome of this project is to generate one or different combination of markers to optimize rectal management and to predict rectal cancer patients outcome more accurately than traditional TNM staging or tumore regression grade. We expect to obtain a prognostic test from normal tissue that accurately predicts rectal cancer behavior even in case when the tumor samples are scarce (early rectal cancer) or absent (complete response to therapy) to avoid unnecessary total rectal excision. Impact On Cancer An immunoscore specific for rectal cancer may predict tumor progression and clinical outcome more accurately and may contribute to better design a personalized therapeutic algorithm. Moreover, nowadays patients with early rectal cancer without nodal involvement and patients with potential complete response to neoadjuvant therapy still undergo total rectal excision which is a risky procedure that impairs quality of life. The use of this new prognostic test may make possible to adopt a minimally invasive approach or even simple observation if nodal involvement or residual disease are reasonably excluded.
Patients with digestive tract malignancy often experience severe and unremitting abdominal pain that negatively affects physical, emotional, and social function, as well as health related quality of life (HRQOL). Therapeutic virtual reality (VR) has emerged as a promising and evidence-based treatment modality for cancer pain. Users of VR wear a pair of goggles with a close-proximity screen in front of the eyes that creates a sensation of being transported into lifelike, three-dimensional worlds. To date, VR has been limited to short-term clinical trials for cancer pain. Moreover, limited research exists on theory-based VR modalities beyond mere distraction, such as VR that employs acceptance and commitment therapy (ACT) with components of biofeedback and mindfulness. To bridge these gaps, this study seeks to: (1) assess the impact of immersive VR on patient-reported outcomes (PROs), including pain, activity metrics, and opioid use among patients with visceral pain from a digestive tract malignancy; (2) assess differences in PROs, activity metrics, and opioid use between skills-based VR therapy vs. distraction VR therapy; and (3) determine patient-level predictors of VR treatment response in visceral cancer pain. To address these aims, the study will measure PROs and opioid use in 360 patients randomized among 3 groups and follow them for 60 days after enrollment: (1) an enhanced VR group receiving skills-based VR; (2) a distraction-based VR group receiving patient-selected VR videos; and (3) a VR sham control group using a VR headset with 2-D content. The results will inform best practices for the implementation of VR for visceral cancer pain management and guide selection of patient-tailored experiences.
There have been many high-quality research publications, including the TNT model of short-term radiotherapy combined with consolidation chemotherapy, and the TNT model of three-drug combination with neoadjuvant chemotherapy with higher treatment intensity combined with CRT. All have achieved better tumor regression and tumor regression than the standard CRT model. The higher pCR rate reduces the recurrence and metastasis events, improves the prognosis, and strives for more opportunities for organ function preservation. Can the TNT model combined with immunotherapy further increase the cCR rate? Whether immunotherapy can bring further survival benefits to patients who develop CR after neoadjuvant therapy (especially W&W after cCR), it is also necessary to carry out corresponding clinical research. We designed this study for patients with mid-to-low and locally advanced rectal cancer who want to be able to preserve the anus. TNT mode combined with PD-1 immunotherapy is given before surgery, and TME surgery is performed on patients who have not reached cCR or who still require surgery. It provides sufficient evidence for the safety and effectiveness of preoperative neoadjuvant therapy for PD-1 in low- and middle-level locally advanced rectal cancer.
Exploration of the experiences and needs of patients with the low anterior resection syndrome, their informal caregiver and health care professionals. This is a qualitative study where semi-structured interviews will be conducted with patients and informal caregivers. next to that focus groups will be performed with healthcare professionals from different professions.
Advances in rectal cancer management have significantly reduced morbidity and mortality. The most commonly performed operation for rectal cancer is restorative proctectomy (RP), leaving up to 70% with long-term bowel dysfunction called Low Anterior Resection Syndrome (LARS). LARS manifests as stool frequency, incontinence and difficult defecation. LARS, along with other functional impairments such as sexual and urinary dysfunction (SUD), can impact quality of life (QoL) and cause emotional distress. High-quality longitudinal data on these sequalae are lacking, leading to variable estimates of their prevalence, risk factors and prognosis. Most studies are European, cross-sectional, lack pre-treatment evaluation and long-term follow-up, and use inconsistent assessment measures. Thus, a North American study that evaluates patients longitudinally from diagnosis will provide quality data to fill this knowledge gap. The main aim of the proposed study is to contribute evidence regarding the impact of LARS, SUD, emotional/financial distress, and patient activation on long-term post-treatment QoL in North American rectal cancer after RP. This multicenter North American, observational, prospective cohort study relies on validated patient reported outcome measures (PROMs) at diagnosis, during and post-treatment. Patients from 20 sites will be recruited over 2 years and followed for 3 years. The primary endpoint is QoL as measured by the European Organization for Research & Treatment of Cancer QoL questionnaire. We anticipate accrual of 1200 patients. Factors associated with QoL will be explored. Impact of patient activation in relation to functional outcomes on QoL over time will be explored using a difference-in-differences approach. The study involves a multidisciplinary team who will provide expertise in research methodology, nursing, oncology and surgery. The main contributions of this study are 1) provision of reference baseline North American values for important rectal cancer PROMs for clinical and research use, 2) an understanding of the evolution of functional outcomes and QoL post-treatment to counsel patients peri-operatively and throughout survivorship, and 3) to provide the basis for future tailored programs to support rectal cancer survivors.
