About this study
Official title: Phase I /II Study of Postoperative Chemoradiation in Patients With Node-positive Esophageal Squamous Cell Carcinoma
This is a unicentered phase I/II study to explore the dose of paclitaxel and cisplatin with radiation therapy, and to document the adverse events for further clinical trial.
Read the detailed description
Although preoperative chemoradiation therapy followed by surgery is the most common approach for patients with resectable esophageal cancer, the considerable number of esophageal cancer patients received operation as the first treatment modality. Accordingly, postoperative treatments have been playing an important role because of the poor survival rates of the patients with pathologically positive lymph nodes who have been treated with resection alone. The investigators have proved the value of prophylactic radiation therapy after radical esophagectomy for esophageal carcinoma with positive lymph node metastases under the conventional 2-dimensional radiotherapy methods in subset analysis of prospective randomized clinical trial. For patients with positive lymph nodes, 5 year survival after surgery alone was 28.4%, median overall survival was 24 months, recurrence occurred 34.6% in mediastinal lymph nodes,13.3% in supraclavicular lymph nodes,10% in abdominal lymph nodes. Distant metastases occurred in 21% patients. Adjuvant radiotherapy significantly reduced the recurrence in mediastinal lymph nodes(13.4%), supraclavicular lymph nodes (6.1%). However distant metastases rate increased to 30.7%. Chemotherapy may be vital for these patients. Chen reported that the 5 year overall survival rates for the chemoradiotherapy group and radiotherapy group were 47.4% and 38.6% (P=0.03). Based on the investigators' studies, treatment failure occurred in 8% patients because of celiac metastases. Small radiation field by omitting celiac axis lymph node basin may ensure 5-6 cycles of concurrent chemotherapy for lower toxicity.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Paclitaxel, Cisplatin and Radiation in people with Esophageal Neoplasms, run by Chinese Academy of Medical Sciences at 1 site in China.
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 5 inclusion and 6 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 24 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Maximum tolerated dose of weekly paclitaxel and cisplatin with concurrent radiation(Phase I endpoint) (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02446574, which also lists 11 linked publications.
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 24 Oct 2017.
