A long-term survival case following salvage stereotactic radiotherapy for local recurrence after definitive chemoradiotherapy for stage III non-small cell lung cancer
2020
A 56-year-old male with stage IIIA (UICC 7th) non-small cell lung cancer (adenocarcinoma) received
radiotherapy with 66 Gy/33 fractions concomitant with CBDCA and PTX. A partial response was achieved after chemoradiotherapy and the tumor continued to shrink over a period of 1 year; however, regrowth of the tumor attached to the aortic arch was observed without any other residual tumor or metastases. We diagnosed recurrence with slightly increased 18F-FDG uptake (maximum standardized uptake value: 12.2). Stereotactic radiotherapy was performed for the relapsed lesion with 60 Gy/10 fractions. The patient has survived for more than 5 years after stereotactic radiotherapy without recurrence or metastases, although he has been suffering from chest pain that has required treatment with a low dose of oxycodone.
