Description:
This trial studies how well proton beam radiation therapy compared with intensity modulated
photon radiotherapy works in treating patients with stage I-IVA esophageal cancer. Proton
beam radiation therapy uses a beam of protons (rather than x-rays) to send radiation inside
the body to the tumor without damaging much of the healthy tissue around it. Intensity
modulated photon radiotherapy uses high-energy x-rays to deliver radiation directly to the
tumor without damaging much of the healthy tissue around it. It is not yet known whether
proton beam therapy or intensity modulated photon radiotherapy will work better in treating
patients with esophageal cancer.

Purpose
This trial studies how well proton beam radiation therapy compared with intensity modulated
photon radiotherapy works in treating patients with stage I-IVA esophageal cancer. Proton
beam radiation therapy uses a beam of protons (rather than x-rays) to send radiation inside
the body to the tumor without damaging much of the healthy tissue around it. Intensity
modulated photon radiotherapy uses high-energy x-rays to deliver radiation directly to the
tumor without damaging much of the healthy tissue around it. It is not yet known whether
proton beam therapy or intensity modulated photon radiotherapy will work better in treating
patients with esophageal cancer.
Detailed Description
PRIMARY OBJECTIVES:
I. To determine if overall survival (OS) is improved with proton beam radiation therapy (PBT)
treatment as compared to intensity modulated photon radiation therapy (IMRT) as part of
planned protocol treatment for patients with esophageal cancer.
II. To determine if OS with PBT is non-inferior to IMRT as part of planned protocol treatment
and that there will be less grade 3+ cardiopulmonary toxicity with PBT than with IMRT.
SECONDARY OBJECTIVES:
I. To compare the symptom burden and impact on functioning of patients between treatment
modalities based on Patient Reported Outcome (PRO) measures of symptoms using MD Anderson
Symptom Inventory (MDASI) and Patient-Reported Outcomes Measurement Information System
(PROMIS)-Fatigue.
II. To compare the Quality-Adjusted Life Years (QALY) using EuroQol five-dimensional
questionnaire (EQ5D) as a health outcome between PBT and IMRT, if the protocol primary
endpoint is met.
III. To assess the pathologic response rate between PBT and IMRT. IV. To assess the
cost-benefit economic analysis of treatment between radiation modalities.
V. To compare the length of hospitalization after protocol surgery between PBT and IMRT.
VI. To compare the incidence of grade 4 lymphopenia during chemoradiation between PBT and
IMRT.
VII. To compare lymphocyte nadir at first follow-up visit after completion of chemoradiation
between PBT & IMRT.
VIII. To estimate the locoregional failure, distant metastatic free survival, and
progression-free survival of patients treated with PBT versus IMRT.
IX. To compare incidence of both early (< 90 days from treatment start) and late (≥ 90 days
from treatment start) cardiovascular and pulmonary events between PBT versus IMRT.
X. To compare the Total Toxicity Burden (TTB) of IMRT versus PBT based on a composite index
of 9 individual cardiopulmonary toxicities.
EXPLORATORY OBJECTIVES:
I. To collect biospecimens for future analyses, for example to assess cardiac and
inflammatory biomarkers in association with treatment complications.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP I: Patients undergo PBT over 28 fractions 5 days a week for 5.5 weeks. Patients also
receive paclitaxel intravenously (IV) and carboplatin IV on days 1, 8, 15, 22, 29, and 36
while undergoing PBT.
GROUP II: Patients undergo IMRT over 28 fractions 5 days a week for 5.5 weeks. Patients also
receive paclitaxel IV and carboplatin IV on days 1, 8, 15, 22, 29, and 36 while undergoing
IMRT.
In both groups, within 4-8 weeks after completion of chemotherapy and radiation therapy,
patients may undergo an esophagectomy per physician discretion.
After completion of study treatment, patients are followed up every 3-6 months for 3 years
and then annually thereafter.

Primary Outcome Measures
Measure: | Overall survival (OS) |
Time Frame: | From the date of randomization to the date of death due to any cause or date of last follow-up for patients without an OS event reported. This analysis occurs after 173 deaths; estimated to occur 4 years after accrual completion |
Safety Issue: | |
Description: | Will be estimated by the Kaplan-Meier method. The distributions of OS between treatment arms will be compared using the log rank test. |
Secondary Outcome Measures
Measure: | Pathologic response rate |
Time Frame: | At time of surgery |
Safety Issue: | |
Description: | A Chi-square test will be used to compare the pathologic response rates between the treatment arms. |
Measure: | Grade 4 lymphopenia during chemoradiation |
Time Frame: | From the start of chemoradiation to the end of chemoradiation treatment assessed up to 31 days |
Safety Issue: | |
Description: | Will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. The proportion of patients experiencing grade 4 lymphopenia during chemoradiation will be compared between treatment arms using a chi-squared test. |
Measure: | Lymphocyte counts |
Time Frame: | From the last date of chemoradiation up to 8 weeks post chemoradiation |
Safety Issue: | |
Description: | Mean lymphocyte counts at first post chemoradiation follow-up will be compared between treatment arms using a t-test. If the data do not satisfy the normality assumption, a Wilcoxin test may be used instead. |
Measure: | Locoregional failure (LRF) |
Time Frame: | From the date of randomization to the date of first LRF or date of last follow-up for patients without an LRF event reported, assessed up to 8 years |
Safety Issue: | |
Description: | Will be defined as local/regional recurrence or progression. Will be estimated by the cumulative incidence method, with death as a competing risk. The distribution of LRF estimates between the two arms will be compared using Gray?s test. The Fine-Gray regression model will be used to analyze the effects of factors, in addition to treatment, which may be associated with LRF. |
Measure: | Distant metastatic-free survival (DMFS) |
Time Frame: | From the date of randomization to the date of first DMFS failure or last follow-up for patients without a reported DMFS event, assessed up to 8 years |
Safety Issue: | |
Description: | Will be defined as appearance of distant metastasis or death due to any cause. Will be estimated by the Kaplan-Meier method and estimates between the two treatment arms will be compared using the log rank test. The Cox proportional hazard regression model will be used to analyze the effects of factors, in addition to treatment, which may be associated with DMFS. |
Measure: | Progression-free survival |
Time Frame: | From the date of randomization to the date of first PFS failure or last follow-up for patients without a reported PFS event, assessed up to 8 years |
Safety Issue: | |
Description: | Will be defined as appearance of local/regional/distant failure or death due to any cause. Will be estimated by the Kaplan-Meier method and estimates between the two treatment arms will be compared using the log rank test. The Cox proportional hazard regression model will be used to analyze the effects of factors, in addition to treatment, which may be associated with PFS. |
Measure: | Quality-adjusted life years (QALY) |
Time Frame: | Assessed up to 8 years |
Safety Issue: | |
Description: | Will be evaluated and compared using EuroQol five-dimensional questionnaire (EQ-5D) only if the primary endpoint is met. |
Measure: | Cost-benefit economic analysis of treatment |
Time Frame: | Assessed up to 8 years |
Safety Issue: | |
Description: | Will be calculated by the visual analog scale (VAS) and index scores form the EQ-5D-5L only be done if primary endpoint is met. Will be compared between treatment arms using a t-test with a 2-sided significance level of 0.05. If there are significant differences, then a cost analysis will be conducted. |
