Radiation Therapy for Relapsed or Refractory Diffuse Large B-Cell Lymphoma: What Is the Right Regimen for Palliation? Adv Radiat Oncol 2022; 7:101016. [PMID: 36420208 PMCID: PMC9677220 DOI: 10.1016/j.adro.2022.101016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 06/23/2022] [Indexed: 01/25/2023] Open
Abstract
Purpose To report objective response rates (ORR), time to local failure (TTLF), and overall survival (OS) among patients with relapsed or refractory diffuse large B-cell lymphoma after salvage- or palliative-intent radiation therapy (RT) and to investigate whether outcomes differed with conventional versus hypofractionated (≥2.5 Gy/fraction) RT. Methods and Materials A single-institution observational cohort study was performed for patients who completed a course of RT for relapsed or refractory diffuse large B-cell lymphoma between January 1, 2008, and April 1, 2020. Predictors of ORR, TTLF, and OS were calculated using univariable and multivariable regression models. The Kaplan-Meier method was used to estimate TTLF and OS, and log-rank analysis was used to compare outcomes. Equivalent dose in 2 Gy fractions (EQD2) was calculated using an α/β of 10. Results One-hundred and sixty-nine patients were treated with 205 RT courses (73 [36%] salvage, 132 [64%] palliative), and hypofractionated RT was used in 100 RT courses (49%). Median RT dose was 30 Gy (range, 8-60 Gy). ORR was 60% for the total cohort (53% and 69% for palliative and salvage cohorts, respectively). Over a median follow-up time of 4 months, median OS in all patients was 5 months (3 and 22 months for palliative and salvage cohorts, respectively). No statistically significant differences in ORR, TTLF, and OS were observed with hypofractionation compared with conventional fractionation. EQD2 ≥35 Gy was associated with improved ORR (odds ratio, 3.79 [1.19-12.03]; P = .024) and prolonged TTLF (0.39 [0.18-0.87]; P = .022), while double-hit receptor status (8.18 [1.08-62.05]; P = .042), cell of origin (3.87 [1.17-8.74]; P = .0012), and bulky disease (≥7.5 cm; 2.12 [1.18-3.81]; P = .012) were associated with inferior TTLF. In the palliative-only cohort, a low-dose regimen of 8 Gy in 2 fractions was associated with similar ORR compared with other fractionation schema but trended towards inferior TTLF (P = .36). Conclusions Hypofractionation is not associated with differences in disease outcomes for patients with relapsed or refractory diffuse large B-cell lymphoma, while higher RT dose (EQD2 ≥35 Gy) may improve ORR and TTLF. Future work is warranted to elucidate the ideal dose and fractionation schema for such patients who will likely also undergo novel systemic agents and cellular therapies.

Abstract
Objectives Few studies on prognostic indicators for primary thyroid lymphoma (PTL) have been presented due to the uncommon nature of the tumor. This is the first study to explore the independent prognostic factors in the 2 PTL subtypes. Methods We retrospectively reviewed 1,653 cases of PTL. The cases comprised 28 Chinese patients from a local cohort and 1,625 patients from the Surveillance, Epidemiology, and End Results database from 1973 to 2013. Statistical analysis was performed to determine the demographics and prognostic factors of PTL patients. Results The disease-specific survival (DSS) and prognostic indicators were significantly different between patients with extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) and patients with diffuse large B-cell lymphoma (DLBCL). Patients with MALT lymphoma were younger (P=0.011) and had lower clinical stage (P=0.014) compared to patients with DLBCL. Cox regression analysis revealed that age, treatment modalities employed, clinical stage, and number of other types of cancer were independent prognostic factors for DLBCL patients. Conclusion PTL demonstrates specific clinical features and is associated with a relatively good prognosis. Older age is associated with poor DSS in both MALT patients and DLBCL patients. Additionally, combination of different treatment modalities is associated with improved DSS in DLBCL patients.

EXCLI JOURNAL 2017; 16:1233-1248. [PMID: 29285019 PMCID: PMC5735338 DOI: 10.17179/excli2017-805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2017] [Accepted: 10/17/2017] [Indexed: 11/10/2022]
Abstract
Patients with advanced aggressive B-cell non-Hodgkin lymphomas (NHL) are usually treated with rituximab in combination with chemotherapy. However, disease relapse rates are high. Radiotherapy (RT) has been shown to be efficacious in treating early-stage NHL but its role in advanced stage diseases is unclear. We performed a systematic review of randomized controlled trials (RCTs) comparing chemotherapy with RT to chemotherapy alone in patients with newly diagnosed advanced aggressive NHL. We searched online databases and pooled similar outcome estimates. For time-to-event outcomes, we estimated hazard ratios (HR) for overall survival (OS) and event-free survival (EFS) using the fixed-effect model. Two RCTs involving 254 patients met inclusion criteria. The trials were single-centre RCTs with follow-up period of five and ten years. Both trials were conducted in the pre-rituximab era. Patients treated with consolidation RT had better OS (HR for mortality 0.61; 95 % CI 0.38 to 0.97) and EFS (HR for mortality 0.67; 95 % CI 0.46 to 0.98) compared to those who received no RT. There was an apparent benefit of RT on local control (OR 0.09; 95 % CI 0.04 to 0.20); although this was estimated as a dichotomous rather than time-to-event outcome. Limited evidence shows benefits of consolidation RT in advanced aggressive NHL. However, we were not able to estimate the effect size with confidence due to small number of trials and sample size. We cannot recommend routine consolidation RT in advanced aggressive NHL. More RCTs with the inclusion of rituximab and PET-CT monitoring are needed.

Validity of reduced radiation dose for localized diffuse large B-cell lymphoma showing a good response to chemotherapy. JOURNAL OF RADIATION RESEARCH 2014; 55:359-363. [PMID: 24187329 PMCID: PMC3951084 DOI: 10.1093/jrr/rrt122] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/27/2013] [Revised: 09/04/2013] [Accepted: 09/19/2013] [Indexed: 06/02/2023]
Abstract
To evaluate the validity of a decrease in the radiation dose for patients who were good responders to chemotherapy for localized diffuse large B-cell lymphoma (DLBCL), 91 patients with localized DLBCL who underwent radiotherapy after multi-agent chemotherapy from 1988-2008 were reviewed. Exclusion criteria were as follows: central nervous system or nasal cavity primary site, or Stage II with bulky tumor (≥10 cm). Of these patients, 62 were identified as good responders to chemotherapy. They were divided into two groups receiving either a higher or a lower radiation dose (32-50.4 Gy or 15-30.6 Gy, respectively). There were no statistically significant differences between the lower and higher dose groups in progression-free survival, locoregional progression-free survival or overall survival. Adaptation of decreased radiation dose may be valid for localized DLBCL patients who show a good response to chemotherapy.

Abstract
Objective To examine the efficacy of different radiation doses after achievement of a complete response to chemotherapy in diffuse large B-cell lymphoma (DLBCL). Methods Patients with stage I-IV DLBCL treated from 1995–2009 at Duke Cancer Institute who achieved a complete response to chemotherapy were reviewed. In-field control, event-free survival, and overall survival were calculated using the Kaplan-Meier method. Dose response was evaluated by grouping treated sites by delivered radiation dose. Results 105 patients were treated with RT to 214 disease sites. Chemotherapy (median 6 cycles) was R-CHOP (65%), CHOP (26%), R-CNOP (2%), or other (7%). Post-chemotherapy imaging was PET/CT (88%), gallium with CT (1%), or CT only (11%). The median RT dose was 30 Gy (range, 12–40 Gy). The median radiation dose was higher for patients with stage I-II disease compared with patients with stage III-IV disease (30 versus 24.5 Gy, p < 0.001). Five-year in-field control, event-free survival, and overall survival for all patients was 94% (95% CI: 89-99%), 84% (95% CI: 77-92%), and 91% (95% CI: 85-97%), respectively. Six patients developed an in-field recurrence at 10 sites, without a clear dose response. In-field failure was higher at sites ≥ 10 cm (14% versus 4%, p = 0.06). Conclusion In-field control was excellent with a combined modality approach when a complete response was achieved after chemotherapy without a clear radiation dose response.

Abstract
PURPOSE To evaluate outcomes of patients treated for aggressive non-Hodgkin lymphoma (NHL) with combined modality therapy based on [(18)F]fluoro-2-deoxy-2-d-glucose positron emission tomography (FDG-PET) response. METHODS AND MATERIALS We studied 59 patients with aggressive NHL, who received chemotherapy and radiation therapy (RT) from 2001 to 2008. Among them, 83% of patients had stage I/II disease. Patients with B-cell lymphoma received R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone)-based chemotherapy, and 1 patient with anaplastic lymphoma kinase-negative anaplastic T-cell lymphoma received CHOP therapy. Interim and postchemotherapy FDG-PET or FDG-PET/computed tomography (CT) scans were performed for restaging. All patients received consolidated involved-field RT. Median RT dose was 36 Gy (range, 28.8-50 Gy). Progression-free survival (PFS) and local control (LC) rates were calculated with and without a negative interim or postchemotherapy FDG-PET scan. RESULTS Median follow-up was 46.5 months. Thirty-nine patients had negative FDG-PET results by the end of chemotherapy, including 12 patients who had a negative interim FDG-PET scan and no postchemotherapy PET. Twenty patients were FDG-PET-positive, including 7 patients with positive interim FDG-PET and no postchemotherapy FDG-PET scans. The 3-year actuarial PFS rates for patients with negative versus positive FDG-PET scans were 97% and 90%, respectively. The 3-year actuarial LC rates for patients with negative versus positive FDG-PET scans were 100% and 90%, respectively. CONCLUSIONS Patients who had a positive interim or postchemotherapy FDG-PET had a PFS rate of 90% at 3 years after combined modality treatment, suggesting that a large proportion of these patients can be cured with consolidated RT.

Abstract
PURPOSE To assess the effect of stereotactic body radiotherapy (SBRT) dose and tumor volume on outcomes in patients with recurrent, previously irradiated squamous cell carcinoma of the head and neck. MATERIALS AND METHODS A total of 96 patients with recurrent, previously irradiated squamous cell carcinoma of the head and neck were treated with SBRT using Cyberknife and Trilogy-intensity-modulated radiosurgery. Kaplan-Meier survival analyses were used to estimate locoregional control (LRC) and overall survival rates. Response was evaluated using positron emission tomography/computed tomography or computed tomography and detailed physical examination. RESULTS The median follow-up for all patients was 14 months (2-39 months). The median dose of prior radiation was 68.4 Gy (32-170 Gy). Patients were divided into 4 SBRT dose groups: I (15-28 Gy/n = 29), II (30-36 Gy/n = 22), III (40 Gy/n = 18), and IV (44-50 Gy/n = 27). The median gross tumor volume (GTV) was 24.3(3) cm (2.5-162 cm). For GTV ≤25 cm(3) (n = 50), complete response rates were 27.8%/30%/45.5%/45.5%, and for GTV >25 cm(3) (n = 46), complete response rates were 20%/25%/42.8%/50% for SBRT groups I-IV, respectively. The 1-/2-/3-year LRC rates for doses 40 to 50 Gy were 69.4%/57.8%/41.1%, respectively, whereas for 15 to 36 Gy, they were 51.9%/31.7%/15.9%, respectively (P = 0.02). The overall 1- and 2-year overall survival rates were 58.9% and 28.4%, respectively. Treatment was well tolerated with no grade 4/5 toxicities. CONCLUSIONS Dose escalation up to 50 Gy in 5 fractions is feasible with SBRT for recurrent head and neck squamous cell carcinoma. Higher SBRT doses were associated with significantly higher LRC rates. Large tumor volume required higher SBRT doses to achieve optimal response rates compared with smaller tumor volume.

Abstract
OBJECTIVES The aim of this study was to assess the safety and outcome of stereotactic body radiotherapy (SBRT) in patients with recurrent previously irradiated squamous cell carcinoma of the head and neck (rSCCHN). METHODS We reviewed our experience with 85 patients who received SBRT for rSCCHN between January 2003 and May 2008. The mean dose of SBRT was 35 Gy (range: 15-44 Gy). The following end points were evaluated: tumor response, time-to-progression, acute and late toxicities, local control (LC) rates and impact of tumor dose and tumor size on LC, and overall survival. RESULTS The median follow-up of all patients was 6 months (range: 1.3-39 months). For those patients who were alive at last follow-up (40%) the median follow-up was 17.6 months. The mean total dose of prior radiation to the primary site was 74 Gy (range: 32-170 Gy). Those patients who received SBRT <35 Gy had significantly lower LC than those with > or =35 Gy at 6 months the median follow-up time (P = 0.014). Tumor responses were 34% complete response, 34% partial response, 20% stable disease, and 12% progressive disease. Among those with an initial tumor response followed by progression (58 patients), there was a median interval of 5.5 months for time-to-progression. The 1-year and 2-year LC and overall survival rates for all patients were 51.2% and 30.7%, and 48.5% and 16.1%, respectively. Overall, the median survival for all patients was 11.5 months (range: 3-51). Treatment was well-tolerated with no grade 4 or 5 treatment-related toxicities. CONCLUSIONS SBRT is feasible and safe with minimal toxicities for treatment of rSCCHN patients with prior radiation therapy deemed to be poor candidates for re-irradiation by conventional means.

Abstract
The role of adjuvant radiotherapy to sites of nodal bulky disease in patients with aggressive diffuse large cell lymphoma (DLCL), and stage IV remain undefined. We began a prospective controlled clinical trial to evaluate impact in event free survival (EFS) and overall survival (OS) in a large cohort of patients with a longer follow-up. Between 1989 and 1995; 341 patients with aggressive DLCL and presence of nodal bulky disease (tumor mass > 10 cm) in pathological proven complete response after intensive chemotherapy were randomized to received either radiotherapy (involved fields, 40 Gy) or not. The 5-year EFS and OS in radiated patients were respectively: 82% (95% Confidence interval (CI): 70-89%) and 87% (95% 80-99%), that were statistically significant to control group: 55% (41-64%) (P < 0.001) and 66% (95% CI: 51-73%) (P < 0.01) respectively. Radiotherapy was well tolerated, acute toxicity was mild and until now late toxicity did not appear. The use of adjuvant radiotherapy improve EFS and OS and probably the possibility of cure in patients diffuse large cell lymphoma with worse prognostic factors. Thus, we felt that adjuvant radiotherapy will be considered as part of the initial treatment in this setting of patients.

Abstract
Developments in the evaluation and systemic management of diffuse large B-cell lymphoma (DLBCL) require ongoing assessment of the role of external beam radiotherapy in management. This review assesses data regarding the use of radiotherapy in the initial management of early stage and advanced DLBCL, and considers the implications of bulky and residual disease, and the contribution of PET scanning, to decisions regarding the use of radiotherapy after chemotherapy. Limited R-CHOP plus radiotherapy, or full dose R-CHOP alone, are both likely to cure approximately 90% of patients with low risk early stage disease. The choice of therapy will depend on considerations of acute and late toxicity of the two approaches, taking into account individual patient risk profiles and preferences. Unfavorable early-stage and advanced-stage disease require treatment with full dose R-CHOP. The presence of bulky disease predicts for a higher risk of relapse, which may be partly ameliorated by the addition of radiotherapy. The rapidity of response on PET scanning, the presence of a posttherapy residual mass, the potential toxicity of radiotherapy and the available salvage options all need to be considered on a patient by patient basis, when considering the use of radiotherapy for advanced disease.

Int J Radiat Oncol Biol Phys 2006; 64:1183-7. [PMID: 16376490 DOI: 10.1016/j.ijrobp.2005.09.030] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2005] [Revised: 09/26/2005] [Accepted: 09/27/2005] [Indexed: 11/17/2022]
Abstract
PURPOSE Patients with chemotherapy-resistant lymphoma have rapidly progressive disease and a poor prognosis. Local symptoms are treated with radiotherapy (RT) for local control. We have reviewed local control and toxicity in patients treated with hyperfractionated accelerated RT. METHODS AND MATERIALS A total of 34 patients received hyperfractionated RT between 1997 and 2003. The radiation dose was 39.9-40.5 Gy in 30 fractions. The median treatment time was 22 days with twice-daily involved-field RT. The median follow-up was 4.4 years. Response was assessed <3 months after RT and was classified as a complete response, a complete response-unconfirmed, a partial response, or no response. Local control was defined as maintenance of local complete response, complete response-unconfirmed, or lack of local progression with a partial response. Recurrence or progression outside the RT volume was regarded as distant disease. RESULTS The median age was 53 years; 20 patients were men and 14 were women. The initial diagnosis was Stage I-II in 56% and Stage III-IV in 44%. The disease bulk was > or =10 cm in 35% (n = 12). The histologic features at diagnosis were follicular in 11 (Grade 1 in 4, Grade 2 in 3, and Grade 3 in 4), diffuse large B-cell in 14, peripheral T-cell lymphoma in 2, Burkitt-like in 1, mantle cell in 2, natural killer cell in 2, plasmacytoma/lymphoma in 1, and T-cell lymphoblastic in 1. The initial treatment was chemotherapy in 32 patients (94%); 71% were refractory to initial chemotherapy and 29% developed a relapse after an initial response. The RT response was complete in 24% (n = 8), complete, unconfirmed in 26% (n = 9), partial in 47% (n = 16), and none in 3% (n = 1). The local control rate was 73% at 1, 2, and 3 years. Grade 1 dermatitis was the most common side effect. CONCLUSION Hyperfractionated RT provided good local control and was well tolerated. This encouraging result requires additional study with comparison to conventional fractionation regimens.

Abstract
Primary T-cell non-Hodgkin's lymphoma (NHL) occurring in the context of acquired immune deficiency syndrome (AIDS) is uncommon. Here, we report and discuss such a case presenting in the rectum, and review relevant literature. Although typical in some respects, the case is, in other ways, somewhat unusual for an AIDS-related NHL (ARL); ARL tends to be B cell and advanced stage and our case was T cell and stage IE. In addition, the patient suffered from concomitant cirrhosis related to hepatitis C. Chemotherapeutic options for ARL were limited early in the AIDS epidemic due to poor tolerability. Although this has largely been mitigated by the advent of highly active antiretroviral therapy, our patient eventually suffered complications of chemotherapy, apparently related more to his liver disease than to either his lymphoma or AIDS, that ultimately brought about his demise.

Abstract
Previous reports have revealed modest results in the management of thyroid lymphoma with radiotherapy alone. This retrospective report evaluates the outcome of patients treated for thyroid lymphoma with radiotherapy alone and with combined modality therapy (chemotherapy and radiotherapy) at a single institution. Twenty-seven patients with stages IE and IIE non-Hodgkin's lymphoma of the thyroid gland were treated between 1960 and 1998 at Barnes-Jewish Hospital, of which 14 patients were stage IE and 13 patients were stage IIE. The median age at diagnosis was 67 years, and there were 21 females and 6 males evaluated. The median follow-up time was 38 months (range: 3-279 months). All patients had histologically proven non-Hodgkin's lymphoma, of which 22 patients (81%) were intermediate grade. Treatment consisted of radiotherapy alone in 19 patients and a combined modality therapy in 8 patients. The median radiation dose to the thyroid bed was 44 Gy, and most patients received a doxorubicin-containing regimen administered prior to radiotherapy. Patient, tumor, and treatment-related characteristics were evaluated using Cox regression analysis. Local-regional tumor control, disease-free survival (DFS), and overall survival (OS) were calculated using the Kaplan-Meier method. Four patients had local relapse in this series, with a crude local tumor control rate of 85%. No factor was determined to be significant for local tumor control. The actuarial 5-year DFS and OS for the entire cohort were 57%, and 56%, respectively. In terms of DFS, both age and stage were statistically significant. The 5-year actuarial DFS for patients less than age 65 years was 83% versus 37% for those more than this age (p = 0.024). Furthermore, the 5-year actuarial DFS for patients with stage I and II disease was 69% and 45%, respectively (p = 0.022). In multivariate analysis, age continued to be significant for DFS (p = 0.049). Overall survival analysis revealed age, local tumor control, and stage to be significant in univariate analysis. Multivariate analysis was further carried out using Cox proportional hazard model, and it revealed age (p = 0.006) and local tumor control (p = 0.007) to be significant. Primary thyroid gland lymphomas have a favorable outcome with appropriate therapy, but prognosis depends on both clinical stage and age at presentation. Because of the risk of both local-regional and distant failure, combined modality approaches that use chemotherapy with radiotherapy are warranted for intermediate- and high grade thyroid lymphoma.

Abstract
Many physicians administer involved field radiation therapy (RT) following brief chemotherapy for localized aggressive non-Hodgkin's lymphoma. Involved field irradiation usually implies treatment to the involved nodal regions with and without the contiguous lymphatic region, however, there is no agreements about its definition. Here we assess the appropriateness of RT irrespective of lymph node regions (localized field) following chemotherapy for patients with early stage diffuse large B-cell lymphoma. The localized field encompassed all original gross tumor volumes before chemotherapy with at least a 2- to 3-cm margin irrespective of lymphatic regions. We also evaluated the suitable radiation dose on the basis of response to chemotherapy. Twenty five eligible patients were treated with 3 cycles of chemotherapy (CHOP) followed by RT. All 25 patients had disease confined to Waldeyer's ring and/or cervical lymph nodes. Twenty two patients in complete response following chemotherapy received 30 Gy, and the remaining 3 in partial response received 40 Gy. With a median follow up of 42 months, both event free and overall survival rates at 2 years were 96.0%. There were no in-field recurrences, however, two patients experienced relapses. One developed central nervous system involvement and subsequently died of his disease. The other had mediastinal and submental lymph node relapse at 32 months, and is alive after salvage chemotherapy. Our study demonstrated that it should be possible to reduce treatment volume to less than the conventional involved field, and to limit the dose of RT in the range of 30-40 Gy.

Abstract
PURPOSE To evaluate the outcome according to treatment modality and prognostic factors in clinical Stage I and II intermediate- or high-grade B-cell lymphomas of the head and neck. METHODS AND MATERIALS We analyzed 155 patients treated between 1983 and 1997, excluding those with the Working Formulation low-grade lymphomas. Of these patients, 88 had Stage I and 67 had Stage II disease. Forty-one patients were treated with radiotherapy (RT) alone, and 114 patients were treated with a combination of RT and chemotherapy. Most of the chemotherapy regimens included anthracycline derivatives. More patients with Stage I disease and more patients with poor performance status were treated with RT alone. The treatment results were evaluated according to the new prognostic index B-ALPS, consisting of tumor bulk, age, lactate dehydrogenase level, performance status, and stage. RESULTS The 5-year overall and failure-free survival rate was 71.5% and 68.3%, respectively, for all 155 patients. The 5-year survival rate was 67% for those treated with RT alone and 73% for those treated with radiochemotherapy (p = 0.13). Among the various potential prognostic factors, age >60 years, World Health Organization performance status 2-4, and tumor size >or=6 cm were associated with poorer survival. The 5-year survival rate was 82% for those with no or one B-ALPS factor, 66% for those with two factors, and 49% for those with three or more factors (p <0.0001). The B-ALPS index appeared to predict the prognosis of these patients better than did the International Prognostic Index. No single prognostic factor was useful to identify patient groups more suitable to treatment with RT alone, but in patients with two B-ALPS risk factors, those treated with radiochemotherapy had a better survival rate and tended to have a better failure-free survival rate than those treated with RT alone. CONCLUSION A proportion of patients with clinical Stage I or II head-and-neck B-cell lymphoma may be successfully treated with RT alone. B-ALPS is a useful prognostic index in this disease.

Abstract
We retrospectively analyzed the clinical outcome of localized aggressive lymphoma treated with chemotherapy and adjuvant radiotherapy. Between 1982 and 1998, 77 patients who were diagnosed as having aggressive lymphoma stage I-II were treated with chemotherapy followed by radiation therapy. The median radiation dose was 44.4 Gy (range, 30-64 Gy). Some patients who achieved complete response after chemotherapy received limited-field radiation to reduce toxicity. Several prognostic factors were analyzed in the overall (OAS) and relapse-free survival (RFS) by both uni- and multivariate analysis. The 5-year rates of OAS and RFS were 74.6% and 70.8%, respectively. Patient age (p = 0.016), radiation dose (p = 0.043), and prognostic score proposed by the Japan Lymphoma Radiation Therapy Group (JLRTG; p = 0.0073) were significant predictive factors for OAS. As for RFS, predictive factors were patient age (p = 0.042), elevated level of serum lactic dehydrogenase (p = 0.046), and JLRTG score (p = 0.05). At the multivariate level, only patient age greater than 60 years was a significantly adverse variable for both OAS (p = 0.0079) and RFS (p = 0.0198). Our treatment strategy was thought to be acceptable with satisfactory outcomes. Limited-field radiation may have possible advantages in toxicity if it does not lead to worsening of the outcome, although a conclusive result could not be obtained by the current analysis.

Abstract
PURPOSE To examine the opinions of radiation oncology experts on the management of lymphomas with respect to staging procedures, treatment plan, radiation target volume, and dose prescription. Our aim was to identify the patterns of practice and areas of controversy that may need to be resolved and be amenable to prospective clinical trials. MATERIALS AND METHODS Radiation oncology experts in lymphoma management were identified from academic centers in the United States, Europe, and Canada. A sample of individuals with a publication record and/or participation in the design and execution of lymphoma clinical trials (n = 33) were mailed a questionnaire of five case scenarios. The experts were asked to specify their approaches to staging investigations, treatment plan, radiation target volume, and dose prescription for each scenario. Radiation fields were indicated by the respondents on a schematic anatomy diagram on the questionnaire. The response rate to the survey was 82% (27/33). RESULTS Staging of lymphomas relied on the use of imaging, because computed tomography of the abdomen and pelvis was recommended in all cases, and computed tomography of the uninvolved thorax was advocated by 70% of respondents. A lymphangiogram and a gallium scan were suggested by, respectively, 26% and 25% of respondents. The overall treatment plan was uniform for the four cases of localized presentations of lymphoma. However, the details of chemotherapy and radiation target volume varied significantly. Variations were observed in recommendations regarding the number of courses of chemotherapy and the extent of radiotherapy. The survey documented significant differences in the recommended radiation therapy (RT) dose (30-50 Gy). The scenario of leptomeningeal relapse in diffuse large B-cell lymphoma documented the most diverse treatment recommendations. These varied from whole-brain radiation alone to systemic and intrathecal chemotherapy, radiation with craniospinal coverage, and high-dose chemotherapy with bone marrow transplantation. CONCLUSIONS This survey demonstrated a high degree of consensus regarding the overall management plan of localized lymphomas among the sampled expert radiation oncologists. However, the recommendations regarding the specifics of chemotherapy and RT remain variable. There is clearly no agreement on the most appropriate RT dose and volume. The large variation in the treatment of leptomeningeal relapse of diffuse large B-cell lymphoma suggests that the optimal treatment in this situation is poorly defined, and the clinical outcome with RT, as well as the rationale for decision making, should be examined in more detail.

Abstract
The purpose of this report was to study the results of external beam radiotherapy for patients with extranodal stage IA non-Hodgkin's lymphoma (NHL). A retrospective review was carried out on 27 patients seen between 1984 and 1998 with stage IA NHL of extranodal sites, and followed up for a minimum of 1 year. Sites involved included eye/orbit (seven), parotid (five), breast (four), Waldeyer ring (four), thyroid (three), other head and neck (two), stomach (one), and prostate (one). All patients had biopsy-proven disease and underwent staging workup to rule out other sites of disease. Histologic analysis revealed 16 patients with low-grade NHL, 9 with intermediate-grade, and 2 with high-grade. Ten patients received chemotherapy before radiation therapy, and eight of them had a complete response. The remaining 17 patients were treated with external beam radiation therapy alone. Radiation was directed to the involved field at 1.8 Gy to 2.0 Gy per fraction to a median dose of 40 Gy (range: 20-50.4 Gy). The median patient age was 71 years (range: 39-85 years); 55% were female, and 45% were male. A complete response was attained in all 27 patients after radiation therapy. There were five failures (all in uninvolved distant sites), and two deaths during the follow-up. Median disease free survival (DFS) and overall survival (OS) have not been reached. The 5-year DFS and OS are 85% and 94%, respectively. Older age at presentation showed a trend toward worse outcome (p = 0.07), but because of the relatively few events, other factors (radiation dose, grade of disease, sex, or the use of chemotherapy) showed no statistical differences among the patients. External beam radiation therapy is a highly effective treatment for stage IA NHL found in extranodal sites.

Abstract
PURPOSE To clarify the role of radiotherapy and chemotherapy in the treatment of patients with localized aggressive non-Hodgkin's lymphomas (NHL) originating in the nasal cavity. METHODS AND MATERIALS The survey, administered at 25 Japanese institutes in 1998, enabled us to collect the clinical data for 787 patients with localized aggressive NHL who were treated between 1988 and 1992. RESULTS There were 42 patients (5%) with nasal lymphomas. Twelve of these patients received radiotherapy alone, and 30 were treated with a combination of radiotherapy and chemotherapy. The median radiation dose was 47 Gy (22-66). Twelve patients were reviewed histopathologically according to REAL (Revised European-American Classification of Lymphoid neoplasms) classification. T-cell or natural killer (NK) cell lymphomas were detected in 9 patients (75%), and diffuse large B-cell lymphomas in 3 (25%). The 5-year overall and disease-free survival (DFS) rates of all patients were 57% and 59%, respectively. The 5-year DFS rate for the 30 patients treated with the combined therapy was 64% and that for the 12 patients treated with radiotherapy alone was 46% (p = 0.021). For the 34 patients with stage-modified International Prognostic Index (m-IPI) 0-1, the 5-year DFS rates of those treated with the combined therapy and radiotherapy alone were 68% and 45%, respectively (p = 0.020), but there was no difference in DFS rate among the two groups of patients with m-IPI 2-3. The 5-year local control rates of the patients who received >46 Gy (n = 22) and < or =46 Gy (n = 20) were 95% and 76% (p = 0.087), respectively. There was no significant difference among the 5-year DFS rates (62% vs. 67%) and local control rates (87% vs. 100%) of the patients with T-cell or NK-cell lymphoma and diffuse large B-cell lymphoma. CONCLUSIONS Patients with nasal lymphomas (m-IPI 0-1) should be treated with combined therapy. For the patients with high risk (m-IPI 2-3), the effectiveness of combined therapy was not clarified because of the small number of the patients. A high radiation dose >46 Gy may need to be used to achieve good local control.

Abstract
PURPOSE To test the hypothesis that prechemotherapy tumor size affects the dose of radiation that should be delivered to intermediate-grade and large-cell immunoblastic lymphomas that have completely responded to cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP)-based induction chemotherapy. METHODS AND MATERIALS From September 1988 through December 1996, 294 patients with newly diagnosed, Stage I-IV, intermediate-grade or large-cell immunoblastic lymphomas were enrolled on 2 prospective protocols at the M. D. Anderson Cancer Center. Treatment consisted of CHOP-based chemotherapy with or without involved field radiotherapy. One hundred seventy-two patients, with 178 nodal sites and 87 nonbony, extranodal sites of disease achieved a complete response to 2-6 cycles of chemotherapy and underwent involved field radiotherapy. Total radiation doses ranged from 30.0 to 50.4 Gy (mean +/- standard deviation: 39.7 +/- 2.5 Gy) over 22-49 days using a daily fraction size of 1.3-2.3 Gy. Because various fraction sizes were delivered, the linear-quadratic model was used to convert total radiation doses to biologically equivalent doses given at 1.8 Gy per fraction (D1.8). An alpha/beta ratio of 10 Gy was used for the lymphomas, resulting in D1.8 ranging from 29.1 to 50.8 Gy. Regression tree analysis was performed on nodal sites of disease to determine which of the following factors were predictive of local control: age, tumor size, D1.8, total radiation dose, and duration of radiotherapy. Based on the results of the regression tree analysis, Kaplan-Meier analysis was used to determine the probability of local control per site as a function of tumor size and D1.8. Regression tree analysis was also performed on patients with nonbony disease who received D1.8 = 29.1-39.1 Gy to determine if small lymphomas could be locally controlled with relatively low doses of radiation. The log-rank test was used to compare local control curves. RESULTS The median length of follow-up among survivors was 63 months. Regression tree analysis of nodal sites identified 3 distinct groups: (a) lymphomas < or = 10 cm and D1.8 = 29.1-39.1 Gy; (b) lymphomas < or = 10 cm and D1.8 = 39.2-50.8 Gy; and (c) lymphomas > 10 cm. For nonbony lymphomas that measured < 3.5 cm, low doses of radiation resulted in excellent local control (5-year rates: 96% vs. 97% for D1.8 = 29.1-39.1 Gy vs. D1.8 = 39.2-50.8 Gy; p = 0.610). For 3.5-10.0 cm lymphomas, higher doses of radiation resulted in better local control (5-year rates: 40% versus 98% for D1.8 = 29.1-39.1 Gy versus D1.8 = 39.2-50.8 Gy, p < 0.0001). A narrow dose range (D1.8 = 39.2-40.7 Gy) was delivered to the 8 lymphomas measuring > 10 cm that completely responded to 6 cycles of chemotherapy, resulting in a 5-year local control rate of only 70%. There was no difference in local control for nodal versus nonbony, extranodal sites of disease. CONCLUSION D1.8 ranging from 29.1 to 39.1 Gy yielded excellent local control for nonbony lymphomas measuring < 3.5 cm that had completely responded to a median of 3 cycles of CHOP-based chemotherapy. D1.8 ranging from 39.2 to 50.8 Gy yielded excellent local control for nonbony lymphomas measuring 3.5-10.0 cm that completely responded to either 3 or 6 cycles of chemotherapy. For nonbony lymphomas measuring > 10 cm that completely responded to 6 cycles of chemotherapy, D1.8 ranging from 39.2 to 40.7 Gy yielded suboptimal local control, suggesting that higher doses of radiation are indicated.

Abstract
PURPOSE Mucosa-associated lymphoid tissue (MALT) lymphoma commonly presents in the gastrointestinal (GI) tract. Supradiaphragmatic MALT lymphoma is less common and its natural history is not well defined. This study was conducted to understand the natural history, to determine the frequency of synchronous disease in the GI tract, and to understand the patterns of disease progression after treatment for supradiaphragmatic MALT lymphoma. PATIENTS AND METHODS We retrospectively reviewed the medical records of 39 patients who presented with supradiaphragmatic MALT lymphoma between 1991 and 1997. RESULTS The median age of patients was 58 years (range, 25-90 years) with 16 male and 23 female patients. The most common primary site was salivary gland followed by ocular adnexa, lung, oral cavity, and others. Sixteen patients underwent esophagogastroduodenoscopy and biopsy (EGD + Bx) and 4 were found to have gastric involvement. Ann Arbor stages were the following: IEA, 17; IIEA, 5, IIEB, 1; and IVA, 16. The initial treatments were: involved field radiation therapy (n = 10), chemotherapy (n = 14), combination of radiation therapy and chemotherapy (n = 9), observation after biopsy (n = 4), antibiotics only (n = 1), and patient refusal of further intervention (n = 1). Seven patients received antibiotics as a part of the initial treatment. Every patient except for 1 was alive at a median follow-up of 39.5 months (range, 3-83 months). Thirty-six patients achieved complete response (CR) to the initial treatment. The actuarial 5-year progression-free survival rate was 83%. Progression of the disease occurred in 4 patients, with 2 in the stomach. Salvage attempts were made to 4 and were successful in 3. Of the 2 patients who relapsed in the stomach, 1 had negative EGD + Bx at the time of initial diagnosis. An EGD + Bx was not done in the second patient. CONCLUSION Supradiaphragmatic MALT lymphoma appears to have a favorable prognosis. However, routine evaluation of the stomach is recommended for patients who present with supradiaphragmatic MALT lymphoma at the time of initial evaluation and at the time of relapse. Patients who failed initial therapy can be successfully salvaged with further treatment.

Abstract
PURPOSE To identify the prognostic factors that specifically predict survival rates of patients with localized aggressive non-Hodgkin's lymphoma (NHL). METHODS AND MATERIALS The survey was carried out at 25 radiation oncology institutions in Japan in 1998. The 5-year event-free (EFS) and overall survival rates (OAS) were calculated, and univariate and multivariate analyses were done to identify which of the following factors, namely, gender, age, performance status (PS), serum lactate dehydrogenase (LDH) level, Stage (I vs. II), tumor bulk (maximum diameter), and treatment, were significant from the viewpoint of prognosis. RESULTS A total of 1141 patients with Stage I and II NHL were treated by the Japanese Lymphoma Radiation Therapy Group between 1988 and 1992. Of them, 787 patients, who were treated using definitive radiotherapy with or without chemotherapy for intermediate- and high-grade lymphomas in working formulation, constituted the core of this study. Primary tumors arose mainly from extranodal organs (71%) in the head and neck (Waldeyer's ring: 36% and sinonasal cavities: 9%). The factors associated with poorer prognosis were age over 60 years old (p < 0. 0001), radiation therapy alone (p < 0.0001), PS = 2-4 (p = 0.0011), (sex male, p = 0.0078), a bulky tumor more than 6 cm in maximum diameter (p = 0.0088), elevated LDH (p = 0.0117), and stage II (p = 0.0642). A median dose of 42 Gy was delivered mainly to the involved fields. Short-course chemotherapy was provided in 549 (70%) patients. The 5-year OAS and EFS rates for all patients were 71% and 67%, respectively. According to the stage-modified International Prognostic Index, the 5-year EFS of the patients with risk factors from 0 to 1 was 76%, 61% for patients with two risk factors, and 26% for patients with three or more risk factors. CONCLUSION Extranodal presentation, especially Waldeyer's ring and sinonasal cavities, is encountered more frequently in Japan than in Western countries. Tumor bulk is an important prognostic factor in patients with localized aggressive extranodal NHL. Short course chemotherapy followed by radiation therapy was associated with prolonged survival in patients with localized aggressive NHLs of extranodal origin and 0-1 risk factor.

Abstract
PURPOSE Primary mediastinal large B-cell lymphoma (PML) has clinicopathologic features distinct from those of other diffuse large-cell lymphomas. However, the optimal treatment for this tumor is evolving, and in particular, the role of radiation therapy remains undefined. We conducted a retrospective review to evaluate the role of radiation therapy in this disease. METHODS AND MATERIALS The medical records of 40 consecutive patients with Ann Arbor Stage I or II PML treated at our institution from January 1980 to December 1995 were reviewed. There were 18 patients with Stage I disease and 22 patients with Stage II disease; 62.5% were women and 37.5% were men. The median age was 32.4 years (range, 17-74 years). The tumor scores were 0 in 1 patient, I in 5 patients, II in 13 patients, III in 7 patients, IV in 4 patients, and unknown in 10 patients. The International Prognostic Index (IPI) was 0 in 10 patients, I in 26 patients, II in 2 patients, and unknown in 2 patients. All patients were treated with doxorubicin-based chemotherapy, and 35 patients received radiation therapy. For most patients who received radiation therapy, an involved field or a modified-mantle field was used, and a dose of 40 Gy in 20 fractions or 39.6 Gy in 22 fractions was administered. Univariate analysis was performed to identify prognostic factors. RESULTS The median follow-up in surviving patients was 56 months (range, 19-194 months). The actuarial 5-year relapse-free survival (RFS) rate and overall survival (OS) rate for all patients were 67% and 72%, respectively. Thirty-five patients achieved a complete response; 32 of these patients received radiation therapy. The patterns of failure for the complete responders were as follows: locoregional failure alone for 1 patient (at the margin of the radiation field); distant failure alone for 5 patients; and both locoregional (in-field) and distant failure for 1 patient. There were no failures after 2.5 years. None of the 5 patients who never achieved a complete response had local control, and all died with disease. Only 2 of the 5 completed the planned course of radiation therapy; both had massive mediastinal disease. There was no treatment-related death from the initial chemotherapy or radiation therapy. One patient developed a second malignancy (sarcoma) within the radiation field after 13 years. The tumor score was a significant predictor of RFS (p = 0.016) and OS (p = 0.006), but the IPI did not prove to be a significant predictor. CONCLUSION We recommend consolidative radiation therapy in view of the excellent local control and the lack of significant toxicity. Modified mantle or involved field appears to be an adequate volume, and 39.6-40 Gy appears to be an adequate dose. The tumor score is a significant prognostic factor.

Abstract
Treatment of localized (stages I, IE, non-bulky II and IIE) aggressive histologies of non-Hodgkin's lymphoma has evolved over the past 20 years. Prior to 1980, these diseases were shown to be locally controlled with radiotherapy, but systemic relapse and death were common. With the discovery of potentially curative doxorubicin- containing chemotherapy, pilot studies during the 1980s demonstrated the utility of combination chemotherapy as initial therapy by increasing the proportion of cured patients. In the 1990s, two large randomized, prospective trials set the benchmark for future comparisons by establishing initial chemotherapy followed by radiation therapy (combined modality therapy) as the best available current treatment strategy.

Abstract
PURPOSE Management of follicular lymphoma after chemotherapy failure has been controversial and has ranged from watchful waiting to high-dose chemotherapy. High-dose chemotherapy with bone marrow reconstitution may produce clinical and molecular complete responses at the risk of serious morbidity and mortality. It has been previously reported that central lymphatic irradiation (CLI) can achieve long-term relapse-free survival in patients with Stage I, II, or III follicular lymphoma. Therefore, we investigated the feasibility of treating patients in whom front-line chemotherapy failed with salvage CLI instead of instituting more intensive chemotherapy. METHODS AND MATERIALS Salvage CLI with curative intent for patients with follicular lymphoma was started at The University of Texas M. D. Anderson Cancer Center in 1992. Eleven patients whose disease showed poor response to or relapsed after chemotherapy were managed with this approach. The median age of the patients was 61 years. Criteria for exclusion included bone marrow involvement or other evidence of Ann Arbor Stage IV disease at any time during the course of the disease. Overall survival and relapse-free survival were calculated from the first day of CLI. RESULTS Ten patients were alive at a median follow-up of 25 months (range 9-73 months). The treatment was well tolerated in general. Two patients could not complete CLI: one 75-year-old patient owing to prolonged platelet count depression and deterioration in general medical condition, and a 66-year-old patient because of exacerbation of preexisting pancytopenia and worsening of heart disease. Everyone who completed CLI remains in remission at the time of this report, except for one patient who had a relapse in the right lacrimal gland at 32 months. This patient was treated with local radiation therapy and is free of disease. Eventual recovery of the blood counts was observed for the patients who completed CLI. CONCLUSION These results demonstrate for the first time that with CLI, it is possible to achieve complete remission of acceptable quality in follicular lymphoma patients who experience a chemotherapy failure. The main toxicity is limited to transient depression in hematological profiles. The treatment is fairly well tolerated and seems to carry little risk compared with high-dose chemotherapy and bone marrow rescue. Salvage CLI may not necessarily compromise future treatment with chemotherapy, including autologous bone marrow or stem cell transplantation, because the patients' blood counts recover.

Abstract
PURPOSE/OBJECTIVE To assess local (in-field) disease control, identify potential prognostic factors, and elucidate the optimal radiotherapy dose in various clinical settings of Stage I and II non-Hodgkin's lymphoma (non-CNS). MATERIALS & METHODS A total of 285 consecutive patients with Stage I and II non-Hodgkin's lymphoma were treated with curative intent, including 159 with radiotherapy (RT) alone and 126 with combined-modality therapy (CMT). Of these, 72 patients had low-grade lymphomas (LGL), 92 had intermediate or high-grade lymphomas (I/HGL), and 21 had unclassified lymphomas. Clinical and treatment variables with potential prognostic significance for in-field disease control, freedom from relapse (FFR), and absolute survival (AS) were evaluated by univariate and multivariate analyses. RESULTS The 5-, 10-, and 20-year actuarial AS rates were 73%, 46%, and 33% for patients with LGL and 64%, 44%, and 18% for patients with I/HGL, respectively. The 5-, 10-, and 20-year actuarial FFR rates were 62%, 59%, and 49% for patients with LGL and 66%, 57%, and 57% for patients with I/HGL, respectively. Significant prognostic factors identified by the multivariate analysis were age, tumor size, and histology for AS; tumor size and treatment for FFR; and only tumor size for in-field disease control. There were 95 total failures, with only 12 occurring infield. Most failures (65%) were in contiguous unirradiated sites. All 4 in-field failures in patients with LGL occurred after RT doses < 30 Gy, although none occurred in 10 patients with small-volume LGL of the orbit treated with doses < 30 Gy. The 8 in-field failures in patients with I/HGL were distributed evenly throughout the RT dose range; 5 occurred in patients treated with CMT, all with tumors > 6 cm, and 4 with less than a complete response (CR) to chemotherapy. CONCLUSION Our analysis suggests that the overwhelming problem in the treatment of non-Hodgkin's lymphoma is not in-field failure but, rather, failure in contiguous unirradiated sites. A dose of 20-25 Gy may be sufficient for small-volume LGL of the orbit. A dose of 30 Gy is sufficient for LGL in general, as well as for patients with nonbulky (< or = 6 cm) I/HGL treated with CMT who have a CR. However, patients with I/HGL treated with CMT for tumors > 6 cm and/or without a CR may benefit from doses > or = 40 Gy.

Abstract
BACKGROUND Outcome in previously untreated patients with non-Hodgkin's lymphoma of the head and neck needed to be assessed. METHODS A retrospective review was performed of 79 patients with stage I or II non-Hodgkin's lymphoma of the head and neck treated between 1964 and 1994 with radiotherapy (RT) or combined modality therapy (CMT) at the University of Florida. Freedom from relapse, cause-specific survival, and absolute survival were analyzed by the Kaplan-Meier method. Patterns of failure were defined, and the relationship between dose and infield recurrence was studied. Histology was classified as low grade or intermediate/high grade. RESULTS At 10 years, absolute survival for patients with low-grade lymphoma treated with RT was 45%; absolute survival for patients with intermediate/high-grade lymphoma was 41% for those treated with RT and 57% for those who received CMT. Twenty-seven patients had a recurrence of lymphoma after initial treatment. Twenty patients (74%) had recurrences outside the radiation treatment field; 90% of these failures were in predictable sites that would be included in comprehensive lymphatic irradiation fields (Waldeyer's ring, mantle, and whole abdomen). No clear dose response was observed. Multivariate analysis showed that patients with tumors <5 cm in diameter had improved cause-specific survival, absolute survival, and freedom from relapse compared with patients with tumors > or = 5 cm in diameter. CONCLUSIONS Patients with non-Hodgkin's lymphoma in the head and neck with tumors > or = 5 cm in diameter appear to have a worse prognosis than those with smaller tumors. The patterns of failure suggest that initial treatment with comprehensive lymphatic irradiation fields could potentially eliminate the majority of treatment failures.

Abstract
PURPOSE To clarify the natural history of primary lymphoma of the small bowel and identify preferred treatments for it. MATERIALS AND METHODS A retrospective analysis of 61 patients with primary lymphoma of the small bowel was performed. The Ann Arbor stages were I in 20 patients, II in 28, and IV in 13. After resection or biopsy, 15 patients were treated with radiation therapy, 26 with chemotherapy, and 16 with combined-modality therapy. Four patients underwent no adjuvant treatment after resection. RESULTS The actuarial 10-year overall survival and relapse-free survival for the patients with intermediate- and high-grade lymphoma were 47% and 53%, respectively. For the patients with low-grade lymphoma, these rates were 81% and 62%. For patients who underwent radiation therapy, combined-modality therapy, or chemotherapy, the recurrence rates inside the abdomen or pelvis were one of 12, two of 15, and five of 20, respectively, and those outside the abdomen or pelvis were four of 12, one of 15, and zero of 20, respectively. Four of the five abdominopelvic recurrences of disease in the chemotherapy group were among the nine patients who had Ann Arbor stage II disease. CONCLUSION Chemotherapy lowered the recurrence rate outside the abdomen or pelvis. Patients with stage II disease may benefit most from radiation therapy.

Abstract
This report clarifies the prognostic factors for survival in localized non-Hodgkin's lymphoma (NHL) of the head and neck and defines optimal regimens for this disease. One hundred-seven untreated patients with Stage I or II NHL of the head and neck were treated with involved field radiation therapy for orbital, nasal, or paranasal lymphoma and extended field radiation for Waldeyer's ring or neck lymphoma. Radiation doses were 39-48 Gy. In the latter half of the study, adjuvant chemotherapy was administered. Of 107 patients, 95 achieved complete response (CR). Of the 12 patients that did not achieve CR, 9 had nasal T-cell lymphoma (NTL) of the lethal midline granuloma type (LMG-NTL). Only one patient who obtained CR relapsed in a previously irradiated area. Age, sex, stage, bulky mass, number of involved sites, LMG-NTL, histologic subtypes, radiation dose, and adriamycin dose were analyzed for prognostic significance for disease-specific survival in NHL by multivariate analysis. LMG-NTL was the most significant prognostic factor (P < 0.001). Patients with higher age also experienced a higher relative risk than patients of > or =60 years of age (P = 0.0063). Dose of adriamycin reached the borderline significance (P = 0.0600). Radiotherapy is excellent for obtaining local control of head and neck NHL. Randomized trials are required to determine the appropriate radiation field and dose in patients previously treated with chemotherapy. LMG-NTL and age were the significant prognostic factors for disease-specific survival.

Abstract
A single institution's experience with the treatment of localized primary lymphoma of the breast (PLB) was analyzed to understand the natural history of this disease and to identify major prognostic factors and optimal treatment. A retrospective analysis of 23 previously untreated patients who met the strict criteria of PLB from 1972 through 1994 was undertaken. All pathologic materials were reviewed and classified by the Working Formulation. The Ann Arbor stages (AASs) were: IE, 17 patients; IIE, five patients; IV, one patients (bilateral breast involvement without distant metastasis). Pathologic findings were: low grade, two patients; intermediate grade, 18 patients (17 with diffuse large-cell lymphoma (DLCL)); high grade, two patients; and unclassifiable, one patient. The treatments after biopsy or mastectomy were: radiation alone, two patients; chemotherapy alone, six patients; and combined-modality therapy, 13 patients. Two patients had mastectomy alone. Overall survival (OS) and relapse-free survival (RFS) were calculated actuarially. Univariate analyses were performed with patient age, treatment modality, AAS, size of the primary tumor (T stage), and International Prognostic Index (IPI) for the 17 patients with DLCL to define prognostic factors. The median follow-up for the surviving patients was 78 months (range, 45-220 months). The 5-year OS and RFS were 74% and 73%, respectively for all 23 patients, and 65% and 70%, respectively, for the 17 patients with DLCL. Statistically significant factors for OS for DLCL were AAS and IPI. Statistically significant factors for RFS were AAS and T stage. With modern staging evaluation and multiagent combination chemotherapy, localized primary non-Hodgkin lymphoma of the breast, especially diffuse large-cell type, has a prognosis as favorable as that of other DLCL. Ann Arbor stage was a significant factor for both OS and RFS.

Abstract
A long survival is rarely observed in patients demonstrating recurrent malignant lymphoma with bulky disease because of the appearance of chemoresistant tumor cells after extensive chemotherapy, and moreover the presence of bulky disease has also been consistently associated with a poorer response rate and a shortened survival, due to the fact that tumor size is the most significant factor for the treatment of non-Hodgkin's lymphoma. We herein describe a case of a 53-year-old woman presenting with the chief complaint of abdominal fullness, who underwent intraoperative radiation therapy (IORT) for recurrent bulky non-Hodgkin's lymphoma in the mesenterium. The patient has had no evidence of tumor recurrence, based on the findings of regular abdominal computed tomographic scans, 60 months after initial chemotherapy and 28 months after IORT.

BACKGROUND Lymphoma of the nasal cavity and paranasal sinuses is a rare presentation of extranodal lymphoma with a natural history that is not well characterized in this era of combination chemotherapy. The goals of this retrospective study were 1) to define the natural history of sinonasal lymphomas; 2) to compare the results of radiation therapy (XRT) alone with those of combined modality therapy (CMT) in the treatment of patients with lymphoma of the nasal cavity and paranasal sinuses; and 3) to define prognostic factors for each treatment. METHODS Between 1947 and 1993, 70 patients with newly diagnosed lymphoma of the nasal cavity and paranasal sinuses were treated. The Ann Arbor stages were: Stage IE: 42 patients; Stage IIE: 14 patients; Stage IIIE: 2 patients; and Stage IV: 12 patients. The distribution of T classifications of the primary tumors was as follows: T1: 2 patients; T2: 16; T3: 18; and T4: 34. Greater than 90% of the patients had intermediate grade lymphoma (Working Formulation), and none had follicular lymphoma. Twenty-eight patients received XRT alone, and 42 received CMT. RESULTS The actuarial 5-year freedom from progression (FFP) and overall survival (OS) rates for the entire group were 57% and 52%, respectively. For patients with localized disease (Stages IE and IIE) receiving CMT, the actuarial 5-year FFP and OS were 83% and 67%, respectively. In multivariate analysis, treatment with CMT (P = 0.0005) and stage (IE vs. IIIE-IV) (P = 0.0001) were associated with improved FFP. In the group of patients receiving XRT, extent of disease (Stage IE, T1-3 vs. Stage IE, T4 vs. Stage IIE-IV) (P = 0.0001) was the only clinical characteristic associated with improved FFP in multivariate analysis. For patients receiving CMT, International Index (0 vs. 1-3 vs. 4, 5) (P = 0.0001) was the only significant factor predictive of improved FFP in multivariate analysis. One patient failed in the central nervous system (CNS) after initial therapy as a result of a radiation therapy marginal miss. CONCLUSIONS In a Western population, patients with localized lymphoma of the nasal cavity and paranasal sinuses have a favorable prognosis when treated with CMT. FFP is significantly improved by treatment with CMT. For patients treated with XRT, extent of disease is the strongest predictor of outcome. International Index is the most significant prognostic factor for patients receiving CMT. Failure in the CNS is rare after initial therapy and is associated with local failure.

Abstract
PURPOSE A single institution's experience with the treatment of localized primary malignant lymphoma of bone (PLB) was analyzed to identify major prognostic factors, toxicity, and optimal treatment for this rare malignancy. METHODS AND MATERIALS A retrospective analysis of 45 previously untreated patients with Ann Arbor stage IE and IIE PLB from 1967 to 1992 was undertaken. All histopathologic material was reviewed. Irradiated patients received at least 40 Gy. Systemic chemotherapy was generally doxorubicin based. Overall survival (OS), progression free survival (PFS), and disease-specific survival (DSS) were calculated actuarially. RESULTS Histologically, there were 41 diffuse large cell, 2 diffuse mixed cell, 1 lymphocytic, and 1 lymphoblastic lymphomas. International Index scores were assessed on 43 patients. Thirty-six patients were treated with chemotherapy and radiation (CMT), five patients were treated with radiation only, and four patients were treated with chemotherapy only. Univariate analysis revealed significantly improved 5-year OS for those patients who had International Index scores of 0 vs. scores of 1 or 2 (85 vs. 53%, respectively, p = 0.004). Analysis failed to demonstrate a difference in OS, PFS, or DSS when comparing radiotherapy alone versus CMT, stage IE vs. stage IIE, or axial skeleton involvement vs. extremities. CONCLUSION The outcome of patients with PLB is relatively favorable in the era of CMT. Doses of radiation in the range of 46 Gy provide optimal local control with an acceptable rate of complications. The International Index is a valid prognostic tool for PLB.

Abstract
BACKGROUND Radiotherapy is part of the treatment protocols in localized low-grade lymphomas as well as localized high-grade lymphomas adjunct to polychemotherapy. Integration of radiotherapy into the treatment of disseminated high-grade lymphomas is controversial. PATIENTS AND METHOD The current literature and our own experience with radiotherapy as part of the treatment of disseminated high-grade lymphomas will be discussed. RESULTS Retrospective analysis of large clinical trials suggest the value of radiotherapy in the treatment of disseminated high-grade lymphomas. Relapse occurs more frequently in non-irradiated regions than in fields of prior radiotherapy. Integration of radiotherapy into treatment protocols seems to be beneficial in patients with bulky disease. A dose/response relationship has been described. The few randomized trials, however, could not clearly demonstrate an advantage of radiotherapy adjuvant to chemotherapy in disseminated lymphomas. A possible advantage can be seen in patients who did not receive more than 4 cycles of polychemotherapy. CONCLUSION Although the value of radiotherapy adjunct to polychemotherapy in disseminated high-grade lymphomas has not been proven in randomized studies retrospective analysis suggest an advantage. A large randomized study should clarify the role of radiotherapy.

Abstract
Great improvement in the treatment of patients with aggressive non-Hodgkin's lymphoma (NHL) has been obtained with the introduction of new combination chemotherapy regimens in the 1970s. The hope that there would be further improvement has waned during recent years due to the fact that some controlled studies did not reveal any better results using the new more intensive treatment regimens. This is the reason for the question: are we doing any better?
