Semi-radical chemoradiotherapy for 53 esophageal squamous cell carcinomas with supraclavicular lymph node metastasis in a single institutional retrospective study.

OBJECTIVE

Outcomes were examined for the cases that received radiotherapy (RT) for esophageal cancer with metastasis to supraclavicular lymph nodes (ScLN) in a single institutional retrospective study.

MATERIALS AND METHODS

Cases examined were 53 consecutive patients with pathologically confirmed esophageal cancer enrolled from our institution who received semi-radical RT from 2001 to 2013. Radiotherapy consisted of a total dose of from 50-50.4 Gy given in 25-28 fractions of 1.8-2.0 Gy with five fractions per week. The chemotherapy regimen included nedaplatin and 5-fluorouracil. All had ScLN metastasis, and all diseases were included in the RT field.

RESULTS

The median follow up time was 42 months for survival patients. Overall survival (OS) and progression free survival (PFS) for 1-, 2-, and 3 years were 39%, 19%, and 12% and 14%, 9%, and 6%, respectively. Acute grade 3-5 esophagitis and neutropenia was seen in 11% and 81%, respectively. Late grade 3-5 toxicity in esophagus, lung, and heart was seen in 4%, 0%, and 0%. Five patients (9%) survived more than 4 year.

CONCLUSION

Although the 2-year PFS was less than 10% and very poor, long term survival for over 4 year was seen in 9% cases. In other words, despite the poor results, the fact remains that some patients were cured with CRT.
