Trial Summary

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor to get specific guidance based on your situation.

What data supports the effectiveness of the treatment involving chemotherapy and radiotherapy for esophageal and gastric cancer?

Research shows that combining oxaliplatin, 5-fluorouracil, and leucovorin with radiotherapy is effective for treating advanced esophageal cancer. Additionally, capecitabine and oxaliplatin have been evaluated as effective alternatives for advanced esophagogastric cancer. ^{1 2 3 4 5}

Is the combination of chemotherapy and radiotherapy safe for esophageal and gastric cancer?

The combination of capecitabine, oxaliplatin, and radiotherapy has been shown to be safe for treating esophageal and gastric cancers, with common side effects including gastrointestinal issues and skin reactions. Capecitabine, in particular, has a favorable safety profile compared to other similar drugs, and prompt management of severe side effects is important. ^{1 2 6 7 8}

What makes the chemotherapy and radiotherapy treatment for esophageal and gastric cancer unique?

This treatment combines capecitabine, an oral form of 5-fluorouracil (5-FU), with radiotherapy, making it more convenient than traditional infusional 5-FU. It also includes oxaliplatin and leucovorin, which have shown safety and efficacy in treating esophageal cancer, and can be administered on an outpatient basis. ^{1 9 10 11 12}

What is the purpose of this trial?

This phase III trial studies how well the addition of radiotherapy to the usual treatment (chemotherapy) works compared to the usual treatment alone in treating patients with esophageal and gastric cancer that has spread to a limited number of other places in the body (oligometastatic disease). Radiotherapy uses high energy x-rays, gamma rays, or protons to kill tumor cells and shrink tumors. Drugs used in usual chemotherapy, such as leucovorin, 5-fluorouracil, oxaliplatin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding radiotherapy to the usual chemotherapy may work better compared to the usual chemotherapy alone in treating patients with esophageal and gastric cancer.

Findings from Research

The combination of oxaliplatin, 5-fluorouracil, and leucovorin with concurrent radiotherapy was found to be safe and effective for treating locally advanced esophageal carcinoma, with 42 patients showing promising results in a structured treatment regimen.

Patients who received preoperative concurrent chemoradiotherapy had a median survival of 28 months, with significant down-staging observed in 16 out of 24 patients, indicating the potential for improved outcomes with this treatment approach.

In a study of 1002 patients with untreated advanced esophagogastric cancer, capecitabine was found to be noninferior to fluorouracil in terms of overall survival, with a hazard ratio of 0.86, indicating it is an effective alternative.

Oxaliplatin demonstrated similar efficacy to cisplatin, with a hazard ratio of 0.92, and was associated with fewer severe side effects, making it a safer option for patients.

In a phase II trial involving 24 patients with resectable esophageal carcinoma, the combination of neoadjuvant therapy using paclitaxel, carboplatin, 5-fluorouracil, and conformal radiotherapy resulted in a 57% pathologic complete response rate, indicating significant effectiveness in shrinking tumors before surgery.

The treatment showed a median overall survival of 31 months and a disease-free survival rate of 57% at 3 years, although some patients experienced significant side effects, including esophagitis and hypotension, highlighting the need for careful monitoring during treatment.

In a study of 35 patients with advanced esophageal cancer, the combination of oxaliplatin, leucovorin, and fluorouracil demonstrated a 40% overall response rate, indicating significant anti-tumor activity.

While the treatment was effective, it also had notable side effects, including a 29% incidence of severe neutropenia and 26% experiencing significant peripheral neuropathy, highlighting the need for careful monitoring of patients.

In a clinical trial involving 142 patients with advanced esophageal squamous cell cancer, adding panitumumab to cisplatin and 5-fluorouracil (CFP) did not improve overall survival compared to CF alone, with median survival times of 10.2 months for CF versus 9.4 months for CFP.

The trial was stopped early due to interim results showing that patients receiving CFP had a higher risk of death related to disease progression, and more serious adverse events were reported in the CFP group, indicating that the addition of EGFR inhibition may not be beneficial in this patient population.

Capecitabine, an oral medication, showed at least equivalent efficacy to intravenous 5-FU plus leucovorin in treating metastatic colorectal cancer, with an overall response rate of 18.9% compared to 15.0% for 5-FU/LV among 602 patients.

Capecitabine had a more favorable safety profile, resulting in significantly lower rates of stomatitis and neutropenia, while being associated with a higher incidence of hand-foot syndrome, making it a convenient and effective alternative to traditional IV treatments.

In a study of 50 patients with nonmetastatic colorectal cancer, adverse reactions were more frequent with the XELOX regimen (capecitabine combined with oxaliplatin), particularly neurotoxicity, thrombocytopenia, and neutropenia, compared to capecitabine monotherapy.

The type of capecitabine formulation (innovative vs. generic) did not significantly affect the safety profile; instead, the chemotherapy scheme used was the main factor influencing the occurrence of adverse reactions.

Capecitabine is an effective oral prodrug for fluorouracil, providing patients with greater convenience and fewer complications compared to traditional infusion therapies, and has been extensively studied in various solid tumors with a favorable safety profile.

While capecitabine can cause gastrointestinal issues and hand-foot syndrome, its overall tolerability is better than that of fluorouracil, and ongoing clinical trials are expected to further explore its use in combination therapies for gastrointestinal and other solid tumors.

Capecitabine, an oral prodrug of 5-fluorouracil, has been shown to be an effective and convenient alternative to infusional 5-FU in the treatment of esophageal, stomach, and pancreatic cancers when combined with irradiation.

Research is ongoing into the benefits of adding a COX-2 inhibitor to treatment regimens for upper gastrointestinal cancers, as these cancers often show high levels of COX-2 expression, which may enhance therapeutic outcomes.

A modified radiochemotherapy regimen for esophageal cancer, involving leucovorin, 5-fluorouracil, and cisplatin, was well tolerated by 33 patients, with a complete response rate of 70%.

The treatment resulted in a median overall survival of 14 months and a 2-year survival rate of 40%, indicating its efficacy, while allowing for outpatient administration for more than one-third of treatment cycles.

In a Phase I study involving 12 patients with advanced esophageal cancer, the combination of UFT/leucovorin, carboplatin, and paclitaxel with radiation therapy showed preliminary efficacy, with 2 out of 3 patients achieving a pathologic complete response after treatment at the higher dose level.

The study identified maximum tolerated doses for the regimen, but also noted significant toxicity, including febrile neutropenia in multiple patients, indicating that while the treatment may be effective, it carries a risk of serious side effects.
