再発・転移をきたしたがん治療の主体は化学療法であるが,少数個の場合はこの限りでない。
Retrospective analyses were performed for 113 patients who had 1-5 abdominal/pelvic lymph node oligometastases and received salvage radiotherapy. Using the equivalent dose in 2 Gy fractions(EQD2)at D50%, EQD2≥60 Gy was defined as the high-dose radiotherapy. The rate of 2-year overall survival(OS)was 63.1%, and that of local control(LC)59.7%. Solitary oligometastasis was significantly associated with favorable OS, and high-dose radiotherapy with LC. Whereas high-dose radiotherapy did not significantly improve OS in the entire cohort, it did in the subgroup of solitary oligometastasis. No significant association between the irradiation dose and adverse event incidence was found.
