두경부에 국한된 Non-Hodgkin's Lymphoma의 방사선치료 성적

Radiotherapy Results of the Non-Hodgkin's Lymphoma in the Head and Neck

1979년 2월부터 1982년 9월까지 서울대학교병원 치료방사선과에서 두경부에 국한된 Non-Hodgkin's Lymphoma환자중 근치적 방사선치료를 받은 54예를 대상으로 다음과 같은 결론을 얻었다. 1. 원발병소의 관해율은 완전관해가 $81\%$, 부분관해가 $19\%$이었다. 2. 2년 생존을 및 무병 생존율은 각각 $57\%,\;45\%$, 이었으며 병기별, 발생부위별, 임파절 종대의 앙측성 여부, 조직아형에 따라 생존율에 통제학적으로 유의한 차이가 있었다. 3. 재발율은 $54.5\%$(24예/44예)로 국소재발이 $29\%$, 원격전이가 $54\%$, 원격전이와 국소재발이 공존했던 경우가 $17\%$로 $92\%$가 2년이내에 재발하였다. 4. 원발병소의 크기가 6cm이상이지나 다발성인 경우, 원발병소가 임파절외 장기 또는 조직아형이 미만성이거나 대세포형인 경우 원격전이율이 높아 국소방사선치료후 전신적 항암요법의 추가치료가 고러되어야 한다.

This is a retrospective analysis of 54 patients with stage I or II Non-Hodgkin's lymphoma involving the head and neck region treated with curative radiotherapy in the Department of Therapeutic Radiology, Seoul National University Hospital during the period of February 1979 through September 1982. The minimum follow-up period was 24 months. The review of histologic slides was available in 36 cases. Waldeyer's ring was the most common extranodal sites $(40\%)$. $41\%$ of patients were in the stage 1 and $59\%$ in the stage II by Ann Arbor classification. Of the 44 patients who responded after radiotherapy, 24 patients$(54.4\%)$subsequently relapsed. Regional recurrence rate was $29\%$, distant metastasis was $54\%$ and simultaneous regional recurrence and distant metastasis was $17\%$. The survival rate and disease free survival at 2 years were $57\%\;and\;45\%$ respectively. Those patients with a large primary lesion (over 6cm in diameter), multiple conglomerated, extranodal site and diffuse ceil type, experienced a high rate of distant metastasis. Therefore it seems desirable to study the use of adjuvant chemotherapy in those patients with a high probability of distant metastasis.
