AbstractTo analyze the effectiveness and toxicities of radiotherapy in indolent non-Hodgkin’s lymphoma (iNHL) patients treated in our institution. Patients with iNHL treated with radiotherapy between 1999 and 2016 were included. The primary endpoint was progression-free survival (PFS). Secondary endpoints were local control (LC), overall survival (OS) and toxicities. PFS, LC, and OS were analyzed using Kaplan–Meier method. Log-rank test was used to investigate the differences between subgroups. Cox proportional hazard model was used for univariate continuous analysis. Seventy-five patients were identified in our institutional database between 1999 and 2016. Fifty-eight (77.3%) had stage I after Ann-Arbor and 17 patients (22.7%) had stage II. The median follow-up was 87 months (95% CI 72–102 months). Median single dose per fraction was 2.0 Gy (range 1.5–2 Gy) and median total dose was 30.6 Gy (range 16–45 Gy). Radiotherapy was performed in 2D (n = 10; 13.3%), 3D (n = 63; 84.0%) and VMAT (n = 2; 2.7%) techniques, respectively. The median PFS was 14.0 years (95% CI 8.3–19.7 years). The estimated PFS after 5 and 10 years were 73.0% and 65.5% in Kaplan–Meier analysis, respectively. The 5- and 10-year LC were 94.9% and 92.3%, respectively. The 5- and 10-year OS were 88.6% and 73.9%. In univariate analyses of PFS, younger patients (≤ 60 years old) had significantly superior PFS to those older than 60 years old (5-year PFS 81.9% vs. 65.1%, p = 0.021). Dose escalation > 36.0 Gy had no prognostic influence in term of PFS (p = 0.425). Extranodal involvement, stage and histology had no prognostic impact on PFS. Depending on the site of lymphomas, the most common acute side effects were: dermatitis CTCAE° I–II (8.0%), xerostomia CTC° I (8.0%), cataract CTC° I (12.0%) and dry eyes CTC° I–II (14.6%). No adverse event CTC° III was reported. Most acute side effects recovered at 3 to 6 months after radiotherapy except for CTC° I cataract and xerostomia. Local Radiotherapy was highly effective for treatment of early stage iNHL with no serious side effects in our cohort. The most acute CTCAE° I–II side effects recovered 3 to 6 months later. Technique advances seem to have further improved effectiveness and tolerability of radiotherapy.Trial registration: Local ethics committee of Ludwig-Maximilian-University (LMU) Munich approved this retrospective analysis on the May 7th, 2019 (Nr. 19–137).

Abstract Purpose/Objective: We performed a systematic review and meta-analysis of chemotherapy alone compared to chemotherapy plus radiation in the management of adult early stage aggressive non-Hodgkin’s lymphoma (NHL). Overall survival (OS) and disease-free survival (DFS) at 5 years were evaluated. Materials/Methods: Randomized trials published after 1990 comparing chemotherapy alone to chemotherapy plus radiation therapy in the management of adult aggressive NHL were identified through searches of MEDLINE and CANCERLIT databases. In addition, a search of ASTRO, ASCO, and ASH Proceedings from 1999 to the present was performed to identify updates of published articles and abstracts. Studies that were limited to GI sites only were excluded. Only studies employing CHOP or CHOP-like regimens and radiation therapy to a minimum dose of 30 Gy were deemed acceptable. Chemotherapy alone regimens had to consist of a minimum of 4 cycles of therapy. All trials reported OS and DFS at 5 years. A meta-analysis was performed using STATA statistical software, including tests for homogeneity and publication bias. Trials were analyzed by risk ratio (RR) method. Results: Five randomized trials (n = 1933, range for individual studies 215 to 647) were identified that met all inclusion criteria. The 5-yr OS and DFS RRs for the addition of radiation therapy to chemotherapy are presented in Figures 1 and 2, respectively. Three studies suggested an OS and DFS benefit with the addition of radiation to chemotherapy and two suggested an improved OS and DFS among patients treated with chemotherapy alone. Only two of the studies reported patterns of relapse (Aviles et al and Horning et al). These studies showed improved local control with combined modality therapy (16 – 23% vs. 4 – 5%). Risk ratios for OS ranged from 0.90 to 1.56. DFS estimates range from 0.89 to 1.82. A meta-analysis was conducted to estimate the overall treatment effects for this group of studies for both OS and DFS. Due to the high degree of heterogeneity among these trials (p-value for heterogeneity <0.001 for both OS and DFS), summarizing these results with a pooled estimate of effect would be inappropriate. Heterogeneity was decreased only marginally with the exclusion of any individual study from the pooled estimate. Conclusions: It remains unclear whether early stage aggressive NHL patients benefit from the addition of radiation to CHOP-based chemotherapy. However, at this time we are not able to delineate those patients who will benefit from radiotherapy from those who will not. Currently CHOP-based chemotherapy plus radiation remains a standard of care in the US for early stage aggressive NHL. However, controversy remains regarding the role of radiation in light of conflicting results. Our ability to draw firm conclusions based on this review is limited due to the study heterogeneity. Differences among study populations may largely account for this heterogeneity.

Abstract Purpose/Objective: To evaluate patterns of recurrence in patients with Hodgkin’s (HL) and non-Hodgkin’s lymphoma (NHL) who subsequently undergo autologous stem cell transplant (ASCT). In this population that has declared itself as high risk, we evaluated time to and sites of relapse relative to initial sites of disease and radiation therapy (RT). This information might enhance understanding of the natural history of these diseases in the setting of modern therapy, influence treatment strategies, and assist in screening decisions. Materials/Method: We analyzed the records of all 281 consecutive patients with refractory or recurrent HL and NHL (indolent and aggressive, as defined at initial diagnosis) who underwent ASCT in our center between 5/92–7/03. Patients were initially diagnosed between 1979–2003 at a median age of 44 years (8–70). 25 patients were unevaluable due to insufficient data, and 68 patients were excluded from analysis because their disease was refractory to initial and salvage therapy. HL patients were segregated according to initial staging (I/II vs. III/IV). Results: Early stage HL patients relapsed at a median of 2.0 years (0.5–10.3) with 87% relapsing in initial disease site(s); 13% (95% CI 3.8–30.1%) relapsed only in new sites. Advanced stage HL patients relapsed at a median of 1.4 years (0.6–10.5) with 96% relapsing in initial site(s); 4% (95% CI 0.1–21.9%) relapsed only in new sites. Indolent histology NHL patients relapsed at a median of 2.1 years (0.5–14.9) with 83% relapsing in initial site(s); 17% (95% CI 7.3–32.8%) relapsed only in new sites. Aggressive histology NHL patients relapsed at a median of 1.0 year (0.3–8.0) with 64% relapsing in initial site(s); 36% (95% CI 26.2–46.2%) relapsed only in new sites. For early stage HD patients, recurrences were predominantly local, and uniformly so in those unirradiated. For all other groups, fewer patients were irradiated than unirradiated and local recurrences predominated regardless of therapy. Conclusions: Almost all patients with HL who relapse and subsequently undergo ASCT initially recur in previous disease sites. Although patients with aggressive histology NHL are more likely to relapse in new sites than patients with indolent NHL, local recurrences predominate in both groups. The median time to recurrence is brief (1–2.1 years). In a population defined by recurrent disease, it is expected that relapses will occur in irradiated sites. Relative protection by RT of local recurrence cannot be determined until all patients, regardless of relapse status, are analyzed. However, these data support an emphasis on local control and suggest that the frequency of screening be most rapid in the early post-therapy years.

PURPOSE: To evaluate a chemotherapy regimen that consisted of ifosfamide administered as an infusion with bolus carboplatin, and etoposide (ICE) supported by granuloctye colony-stimulating factor (G-CSF) for cytoreduction and stem-cell mobilization in transplant-eligible patients with primary refractory or relapsed non-Hodgkin's lymphoma (NHL).PATIENTS AND METHODS: One hundred sixty-three transplant-eligible patients with relapsed or primary refractory NHL were treated from October 1993 to December 1997 with ICE chemotherapy at Memorial Sloan-Kettering Cancer Center. Administration of three cycles of ICE chemotherapy was planned at 2-week intervals. Peripheral-blood progenitor cells were collected after cycle 3, and all patients who achieved a partial response (PR) or complete response (CR) to ICE chemotherapy were eligible to proceed to transplantation. Event-free and overall survival, ICE-related toxicity, and the number of CD34+cells collected after treatment with ICE and G-CSF were evaluated.RESULTS: All 163 patients were assessable for response, and there was no treatment-related mortality. A major response (CR/PR) was evident in 108 patients (66.3%); 89% of the responding patients underwent successful transplantation. Patient who underwent transplantation and achieved a CR to ICE had a superior overall survival to that of patients who achieved a PR (65% v 30%; P = .003). The median number of CD34+cells/kg collected was 8.4 × 106. The dose-limiting toxicity of ICE was hematologic, with 29.4% of patients developing grade 3/4 thrombocytopenia. There were minimal nonhematologic side effects.CONCLUSION: ICE chemotherapy, with ifosfamide administered as a 24-hour infusion to decrease CNS side effects, and the substitution of carboplatin for cisplatin to minimize nephrotoxicity, is a very effective cytoreduction and mobilization regimen in patients with NHL. Furthermore, the quality of the clinical response to ICE predicts for posttransplant outcome.

Twelve patients with lymphocytic lymphoma (L.L.), and 9 patients with histiocytic lymphoma (H.L.), stage III and IV, were treated as outpatients with combination chemotherapy including six courses of cyclophosphamide (Endoxan), Methotrexate, and vincristine (M.E.V. regimen). Marrow depression and side-effects were moderate. In the 12 patients with L.L., there were 6 complete remissions (C.R.), 3 incomplete remission (I.R.), and 3 partial failures (P.F.). In the 9 patients with H.L., there were 7 C.R., 1 I.R. and 1 P.F. Median survival from the end of the therapy is 7 + mos. for the L.L. patients, and 10 + mos. for H.L. patients, all patients being alive but one.
