FOLFOXIRI Chemotherapy Alone as Neoadjuvant Treatment for Circumferential Radial Margin (CRM) Positive Rectal Cancer

FOLFOXIRI Chemotherapy Alone as Neoadjuvant Treatment for MRI-defined Circumferential Radial Margin (CRM) Positive Rectal Cancer

Neoadjuvant 5-Fu based chemoradiation followed by surgery is a standard treatment for locally advanced rectal cancer. However, radiation-related side effects could not be neglected. But this multimodality strategy failed to improve survival. Neoadjuvant chemotherapy alone may be an alternative strategy to minimize treatment-related toxicities without compromising the oncology outcome. Thus, patients with MRI-defined CRM-positive rectal cancer will receive 6 cycles of neoadjuvant treatment with FOLFOXIRI followed by surgery. The purpose of the study is to evaluate the efficacy of FOLFOXIRI alone as neoadjuvant treatment in treating patients with locally advanced rectal cancer.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Preoperative chemoradiotherapy has been considered for years the standard treatment to patients with locally advanced rectal cancer. However, this multi-modality treatment has been questioned since more evidences suggested that radiotherapy may not be a necessary component of this treatment, and by omitting radiotherapy it have the advantage of reducing acute and late treatment-related toxicities. Given the high anti-tumor of systemic chemotherapy alone, any patients with CRM involvement could be theoretically deemed candidate for an approach in which radiotherapy is delivered preoperatively if a substantial tumor downsizing is not achieved after upfront systemic chemotherapy or postoperatively if the pathologic CRM is involved. This single phase Ⅱ trial was aimed to evaluate the efficacy of FOLFOXIRI in treating patients with MRI-defined CRM-positive rectal cancer. All patients will receive the regimen every 2 weeks for 3 cycles. MRI of the pelvic will be performed after 3 cycles of chemotherapy to assess clinical response. If the tumor responds after 3 cycles of treatment, the patient will continue for another 3 cycles of treatment before surgery under the decision of MDT. On the contrary, if the tumor shows no response, radiotherapy will be given before operation. After surgery and pathologic CRM is not involved, 6 cycles of mFOLFOX6 will be given as adjuvant chemotherapy, otherwise postoperative radiotherapy will be given if the pathologic CRM is involved.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 66 years (Adult, Older Adult)
