Trial summary

Neoadjuvant chemoradiation (CRT), is considered the standard treatment of locally advanced rectal cancer with a positive impact on locoregional control and survival.However, patients with T4 rectal cancer show high risk of local recurrence after conventional treatment. Read more about this study

About this study

Official title: Concurrent Chemoradiation With Concomitant Boost In Locally Advanced Rectal Cancer: A Phase II Study.

Neoadjuvant chemoradiation (CRT), is considered the standard treatment of locally advanced rectal cancer with a positive impact on locoregional control and survival.However, patients with T4 rectal cancer show high risk of local recurrence after conventional treatment. Therefore investigators designed a prospective Phase II study on patients with locally advanced rectal cancer or locally recurrences, to evaluate the efficacy in terms of pathological response and resectability of concomitant boost RT (55 Gy/5 weeks) with concurrent Raltitrexed and Oxaliplatin (Tom-Ox) chemotherapy.

Read the detailed description

Neoadjuvant chemoradiation (CRT), is considered the standard treatment of locally advanced rectal cancer with a positive impact on locoregional control and survival. However, patients with T4 rectal cancer show high risk of local recurrence (LR) after conventional treatment. This was a prospective Phase II study on patients with locally advanced rectal cancer or locally recurrences, to evaluate the efficacy in terms of pathological response and resectability of concomitant boost RT (55 Gy/5 weeks) with concurrent Raltitrexed and Oxaliplatin (Tom-Ox) chemotherapy. The primary aim was to assess the pathological complete response rate. Key secondary aim was the resectability. Secondary aims were evaluation of treatment-related acute and late toxicity, local control, disease-free survival and overall survival (OS). The follow-up period of each subjects started after the radiochemotherapy treatment and ended after a maximum of 36 months of observation or until death.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RadiotherapyRadiation

    Radiotherapy was applied as conformal 3-D technique and was delivered with photon energies of 10 - 15 MV. The beams were delivered by an Elekta Precise Linac equipped with standard multi leaf collimators (MLC). A daily online check of isocenter position was performed using portal imaging, with set-up correction in case of displacement > 0.5 cm in any direction. Radiation dose delivered to PTV2 was 45 Gy (1.8 Gy/fraction) with a concomitant boost dose to the PTV1 of 10 Gy with accelerated fractionation at 2.2 Gy/fraction, five consecutive days for week.

  • Tom-OXDrug

    Also called Tomudex ®, Eloxatin ®

    The concurrent chemotherapy consisted of 15 min intravenous infusion Raltitrexed (Tomudex ®) 3 mg/m2 and a two-hours intravenous infusion of Oxaliplatin (Eloxatin ®) at 130 mg/m 2, 20 min after raltitrexed, on days 1, 17, 35.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of patients defined as good responders (G1 or G2) according to the Mandard regression grading system.

    Pathologic responses of the primary tumours were defined according to the Mandard regression grading system: grade 1 was recorded when no tumour cells remained in the primary tumour and lymph nodes (pCR); grade 2 was characterized by the presence of rare residual cancer cells scattered through the fibrosis; grade 3 was characterized by an increase in the number of residual cancer cells, but fibrosis still predominated; grade 4 showed residual cancer outgrowing fibrosis; and grade 5 was characterized by an absence of regressive changes. Good responders were defined those patients with a pathologic response with Mandard G1 or G2 and poor responder patients with Mandard G3, G4 or G5.

    Measured: 8 weeks after chemo-radiotherapy

Secondary outcomes (4)
  1. Number of patients in which a surgical resection was feasible

    Measured: 8 weeks after chemo-radiotherapy

  2. Number of participants with treatment-related adverse events as assessed by CTCAE v3.0

    CTCAE v 3.0 was used to score acute and late radiation toxicity.

    Measured: Up to 36 months. In details, follow-up examinations were performed 4 weeks after surgery and every 6 months until the established length of follow-up or death.

  3. The number of patients without disease (i.e. rectal cancer) during the follow-up.

    The disease-free survival (DFS) was defined as the time from the diagnosis to the documented local or distant recurrence or last follow-up.

    Measured: Up to 36 months.

  4. The number of patients still alive at the end of follow-up

    The overall-survival (OS) was defined as the time from the diagnosis until death for any cause or the last follow-up.

    Measured: Up to 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Radiotherapy and Tom-OX in people with Rectal Neoplasms, run by IRCCS Azienda Ospedaliero-Universitaria di Bologna.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of patients defined as good responders (G1 or G2) according to the Mandard regression grading system. (time frame: 8 weeks after chemo-radiotherapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2016.
