title: Combined modality therapy for stage I-II large cell lymphoma.
abstract: Between January 1978 and December 1986, 94 patients with Stage I-II large cell lymphoma were evaluated at Stanford University Medical Center and treated with a combination of chemotherapy (CTX) and irradiation (XRT). The predominant histology was diffuse large cell (78), followed by immunoblastic (7), follicular large cell (6), and diffuse mixed small and large cell lymphoma (3). Twenty-three patients had Stage I and 71 had Stage II disease. Fifty-one had extranodal involvement (13 IE, 38 IIE), and 11 had B symptoms (2 IB, 9 IIB). Lymphoma was supradiaphragmatic in 58 patients, infradiaphragmatic in 21, and only in extranodal sites in 15. Patients received either involved (81) or extended (13) field XRT with a median dose of 40 Gy and combination CTX with 2 to 9 cycles (median 6) of either CHOP (68), M-BACOD (8), C-MOPP (8), MACOP-B (4), or other (6). Seventy-two patients remain with no evidence of disease, 21 are dead with disease, and one suffered an intercurrent death. Among the 19 patients who relapsed, there were six failures within the XRT field only, two within and outside the XRT field, and 11 outside of the XRT fields only. Actuarial survival and freedom from relapse (FFR) for the entire population were 74% and 72% at 5-years, respectively (33 month median follow-up). Stage I patients achieved 81% survival and 78% FFR, and Stage II patients had 72% survival and 70% FFR. In univariate and multivariate analyses, a favorable outcome was associated with the CTX-XRT-CTX sequence of therapy (p = 0.001), low LDH (p = 0.01), and small tumor bulk (p = 0.04). There were no relapses or deaths among the 21 patients receiving the "sandwich" sequence (CTX-XRT-CTX) of therapy. This series may serve as a comparison with single modality treatment programs for localized large cell lymphoma using either XRT or CTX alone.
