Hodgkin's disease with a mediastinal mass greater than 10 cm: results of four different treatment approaches.

BACKGROUND: Management of Hodgkin's disease (HD) and large mediastinal adenopathy (LMA) usually includes intensive chemotherapy (CT) with or without radiation therapy (XT) regardless of stage. PATIENTS AND METHODS: One hundred and eighteen evaluable patients received one of four treatment regimens: (1) 6 cycles of MOPP or similar CT and XT; (2) 2 of MOPP followed by XT; (3) 6 of CVPP/ABDIC (cyclophosphamide, vincristine, procarbazine, prednisone/doxorubicin, bleomycin, decarbazine, prednisone, lomustine) followed by XT; or (4) 3 of NOVP (mitoxantrone, vincristine, vinblastine, procarbazine) and XT. XT doses included 30-40 Gy to areas of nodal involvement noted prior to therapy. RESULTS: Complete remission (CR) rates for groups 1, 2, 3, and 4 were 100%, 85%, 87%, and 96%. Respective 3-year freedom from progression (FFP) results were 88%, 66%, 82%, and 88%, and 3-year freedom from tumor mortality (FTM) results were 100%, 84%, 84%, and 100%. The presence of B symptoms and stage IV disease was correlated with lower CR and 3-year FFP rates but similar 3-year survival. CONCLUSIONS: Results of this study suggest that patients with stage I-III Hodgkin's disease and LMA greater than 10 cm treated with 3 NOVP and XT have results similar to those obtained for a similar group of patients treated with 2 to 6 MOPP or 6 CVPP/ABDIC and XT. NOVP has also been reported to produce limited toxicity in this trial and should be considered as an alternative to MOPP or doxorubicin-containing regimens in treatment of patients with early-staged disease and LMA greater than 10 cm.

Growth inhibition of follicular small-cleaved-cell lymphoma cells in short-term culture by interleukin-3.

BACKGROUND: The role of interleukin-3 (IL-3) in stimulating the growth of early myeloid progenitor cells is very well established. Therefore, IL-3 has been incorporated into many post-bone-marrow transplantation and intensive chemotherapy programs for the treatment of solid tumors and hematologic malignancies, including lymphomas. However, the effect of IL-3 on normal and malignant lymphocytes has not been well studied. PURPOSE: The purpose of this study was to evaluate the in vitro effect of IL-3 on the growth of follicular small-cleaved-cell lymphoma (FSCCL). MATERIALS AND METHODS: IL-3 receptor expression on the surface of CD19+ cells was determined by two-color flow cytometry measuring the receptor-binding of biotinylated IL-3 to CD19+ B-cells. Seven cases of FSCCL were compared to six normal controls. Cell proliferation was evaluated by [3H]thymidine incorporation into cells grown in suspension cultures. RESULTS: All seven cases of FSCCL expressed the IL-3 receptor on the surface of CD19+ cells, whereas all six cases of CD19+ cells isolated from the peripheral blood of normal donors did not express IL-3 receptors. IL-3 had antiproliferative activity against FSCCL as manifested by a decrease in [3H]thymidine incorporation and a decrease in the total number of cells after 72 hours of culture. CONCLUSION: IL-3 inhibits the growth of FSCCL cells in vitro. Clinical trials to evaluate the in vivo effect of IL-3 in patients with FSCCL are warranted.

Primary mediastinal large cell lymphoma is characterized by an inverted pattern of large tumoral mass and low beta 2 microglobulin levels in serum and frequently elevated levels of serum lactate dehydrogenase.

BACKGROUND: Primary mediastinal large cell lymphoma (PMLCL) is an emerging entity. New parameters can help define it. MATERIALS AND METHODS: Retrospective analysis of medical records from 35 patients treated at The University of Texas M.D. Anderson Cancer Center from 1985 to 1990. Immunohistochemical evaluation of tissue specimens. Determination of survival (S) and time to treatment failure (TTF). RESULTS: The median age was 34 years and 69% were females. Eight-three percent presented with symptoms of mediastinal involvement. While 100% of the patients presented with bulky mediastinal disease and 72% had elevated pretreatment serum lactate dehydrogenase, only 6% presented with an elevated pretreatment serum beta 2 microglobulin. The lymphoma cells lacked CD21 staining. For the 18 patients treated initially at M.D. Anderson Cancer Center, S and TTF curves rates after doxorubicin-based regimens (plus radiotherapy in 14 cases) were 72% and 61%, respectively, at 5 years follow-up (median, 42 months). Four out of six patients who received autologous bone marrow transplant as salvage therapy are currently alive without disease at follow-up times of 21, 25, 32, and 54 months. CONCLUSION: Primary mediastinal large cell lymphoma has characteristic clinicopathological features to which another can be added, that of an inverted pattern of bulky disease, high LDH and low beta 2 M in serum. The response to therapy is comparable to that of intermediate-grade lymphomas, although the numbers in the study are small. Our preliminary data suggest a possible role for autologous bone marrow transplantation (ABMT) as salvage therapy.

Phase I study of the combination of fludarabine, mitoxantrone, and dexamethasone in low-grade lymphoma.

PURPOSE: Fludarabine is an active agent for patients with low-grade lymphoma (LGL) but has mainly been used as a single agent. This trial was designed to define the maximum-tolerated dose (MTD) of a combination of fludarabine, mitoxantrone, and dexamethasone (FND), to identify the toxicities of these agents in combination, and to make preliminary observations about the efficacy of this combination. PATIENTS AND METHODS: Twenty-one patients with recurrent LGL or follicular large-cell lymphoma were treated, in cohorts of three, at stepwise escalating doses. Patients were required to have adequate marrow function and normal renal, hepatic, and cardiac function. RESULTS: The MTD of the combination was found to be as follows: fludarabine, 25 mg/m2/d (days 1 to 3); mitoxantrone, 10 mg/m2 (day 1); and dexamethasone, 20 mg/d (days 1 to 5). Each course was administered monthly, and up to eight courses were given. Dose-limiting toxicities were neutropenia and infections. Thrombocytopenia was modest. Nonhematologic toxicity was very modest. Responses were seen at every dose level. The overall response rate was 71%, with a 43% complete remission (CR) rate. The median duration of CR was 18 months (with follow-up duration from 13 to 28+ months). CONCLUSION: FND was well tolerated in this population. While our primary aim was to define the MTD, our preliminary observations on the efficacy of the regimen were favorable. The overall response rate was high, there was a high fraction of CRs, and our early impression is that these responses are durable.

ESHAP--an effective chemotherapy regimen in refractory and relapsing lymphoma: a 4-year follow-up study.

PURPOSE: This study attempted to determine the efficacy of the combination of etoposide (VP-16), methyl-prednisolone, and cytarabine (Ara-C) with or without cisplatin in relapsing and refractory adult lymphoma patients. PATIENTS AND METHODS: The first 63 patients were randomized to receive VP-16 40 mg/m2/d for 4 days, methylprednisolone 500 mg intravenously daily for 5 days, and Ara-C 2 g/m2 intravenously over 2 to 3 hours on day 5 with or without cisplatin 25 mg/m2 IV administered by 24-hour infusion for 4 days (ESHA +/- P). Markedly different responses between ESHA (33%) and ESHAP (75%) led to deletion of the ESHA arm. A total of 122 patients on the ESHAP regimen were studied. RESULTS: Forty-five patients (37%) attained a complete remission (CR) and 33 (27%) attained a partial remission (PR), for a total response rate of 64%. The median duration of CR was 20 months, with 28% of remitters still in CR at 3 years. The overall median survival duration was 14 months; the survival rate at 3 years was 31%. Overall time to treatment failure (TTF) showed 10% of all patients to be alive and disease-free at 40 months. Response and survival rates were similar in patients with low-grade (n = 34), intermediate-grade (n = 67), transformed (n = 18), and high-grade (n = 3) lymphoma. The most significant factors for response and survival by multivariate analysis were the serum lactic dehydrogenase (LDH) level, tumor burden, and age (when analyzed as a continuous variable), while prior CR was highly significant by univariate analysis. A significant difference in survival was noted for patients with normal LDH levels and low- or intermediate-tumor burden or patients with low tumor burden and elevated LDH levels (55% 3-year survival rate) versus patients with elevated LDH levels and intermediate or high tumor burden (< 20%). Major toxicities included myelosuppression, with a median granulocyte count of 500/microL and platelet count of 70,000/microL. CONCLUSION: ESHAP was found to be an active, tolerable chemotherapy regimen for relapsing and refractory lymphoma. Applying a prognostic model based on tumor burden and serum LDH level shows significant differences in survival in this patient population.

Hodgkin's disease: study of treatment intensities and incidences of second malignancies.

BACKGROUND: Advances in radiotherapy and chemotherapy have gradually increased cure rates for patients with Hodgkin's disease. With improved long-term survivals, increases in observed second malignancies over those of the general population have been reported as early as 1972. Recently, a number of investigators have suggested that the relative importance of recognized risk factors contributing to the development of acute myelogenous leukemia (AML), non-Hodgkin's lymphomas, and solid tumors may be different. Our study is concerned with the influence of various risk factors on patients who have been treated with modern radiotherapy and combination chemotherapy between 1966 and 1987. PATIENTS AND METHODS: We reviewed the records of 1,022 patients with Hodgkin's disease of whom 1,013 had sufficient data for analysis. Kaplan-Meier methodology was used to calculate overall and determinate survivals and occurrences of acute myelogenous leukemia, non-Hodgkin's lymphoma, and solid tumors. The observed to expected incidences, calculated from the SEER incidence and population files for 1976, were compared. Using Cox's proportional hazards model, the following were analyzed singly for risk significance for the entire population: age, stage, splenectomy, treatment modality, treatment intensity, and number of treated relapses. Separate analyses were performed to determine the relative risks for subsets of the population. These included pelvic radiotherapy for those with stage III disease and specific alkylating agents for patients who were treated with chemotherapy only. RESULTS: Sixty-six instances of second malignancy were documented as follows: AML 14, non-Hodgkin's lymphoma 14, and solid tumors 38. The overall incidence of second malignancy was significantly greater than the expected incidence of 21.75 (p = 0.0001) and it was also significant for AML, non-Hodgkin's lymphoma and solid tumors. Analyses for risk of second malignancy demonstrated that age > or = 40 years, stage III or stage IV disease, and treatment with chemotherapy only were all associated with a significantly higher risk of second malignancy than any of the other factors. However, only treatment with regimens containing nitrogen mustard had a significantly higher risk for second malignancy. Treatment intensity and number of treated relapses had no specific effect on risk. Joint modeling of age, stage, and treatment showed that the combination of age and stage was the most significant risk factor for AML and non-Hodgkin's lymphoma (p = < 0.0003). However, only age was important for solid tumors. CONCLUSIONS: Our analysis suggests that the most critical host factor for developing a second malignancy was age. The fact that patients with stages III and IV disease had an increased risk of second malignancy regardless of age suggests that biologic factors related to the tumor also may have been significant. However, it is possible that the effect of treatment was hidden by stage.

CHOP-Bleo plus interferon for stage IV low-grade lymphoma.

BACKGROUND: Alpha interferon (IFN) is an effective single agent for patients with low-grade lymphoma, but until 1982 had not been integrated with standard chemotherapy for these patients. Since relapse from complete remission (CR) is the rule for patients with advanced stage low-grade lymphoma, a maintenance IFN schedule was explored for patients in CR. PATIENTS AND METHODS: From 1982-1987, 127 patients with stage IV low-grade lymphoma were treated with cyclophosphamide, doxorubicin, vincristine, prednisone, and bleomycin (CHOP-Bleo) for 9-18 mo. (median 13 mo.), followed by interferon alfa-n-1 (Wellferon) maintenance therapy for 24 mo. for CRs. RESULTS: The overall response rate for the entire treatment program was 73% CR and 23% partial remission. The median follow up was 59 months. At 5 years, survival was 74%, failure-free survival (FFS) 47%, and FFS of CRs 60%. Compared to a group of 96 patients with similar pretreatment clinical features treated with CHOP-Bleo from 1972-1982, this represents a significant improvement for both overall FFS (p = 0.01) and FFS of CRs (P < 0.01). Toxicity from the IFN maintenance was generally acceptable, but even at the modest dose employed in this trial (3 x 10(6) U/m2 three times weekly), dose modification was required in more than 30% of patients, usually because of fatigue. CONCLUSIONS: The integration of IFN and conventional chemotherapy is feasible and effective. Maintenance IFN prolongs remission duration for patients with stage IV low-grade lymphoma.

Prognostic role of serum beta 2-microglobulin in Hodgkin's disease.

PURPOSE: To evaluate the role of serum beta 2-microglobulin (beta 2M) in the prognosis of patients with Hodgkin's disease. PATIENTS AND METHODS: One hundred sixty previously untreated patients with Hodgkin's disease had serum beta 2M levels determined before initiation of treatment. Serum beta 2M was tested for its correlation with known prognostic factors for patients with Hodgkin's disease. These variables, including beta 2M, were correlated with complete remission (CR) rate and time to treatment failure (TTF). Univariate and multivariate analyses were performed. RESULTS: Serum beta 2M levels greater than 2.5 mg/L were found in 29% of patients. Such elevation was more common in patients with more advanced-stage disease. Elevated serum beta 2M was an independent and powerful factor in the prediction of lower response rate and shorter TTF. Its impact appeared to be more significant in patients with advanced disease. CONCLUSION: Serum beta 2M appears to correlate with tumor stage in patients with Hodgkin's disease and elevated serum levels of this polypeptide predict a less favorable prognosis.

Radiotherapy during pregnancy for clinical stages IA-IIA Hodgkin's disease.

Between 1956 and 1990, 775 women were treated for Hodgkin's disease at The University of Texas M.D. Anderson Cancer Center. Of these, 25 (3.2%) were pregnant at diagnosis. Seven of these women were in the first trimester, 10 in the second, and eight in the third. Prior to treatment, three women in the third trimester had normal deliveries, and six patients in the first trimester had abortions. Sixteen patients received radiotherapy for supradiaphragmatic presentations during their pregnancies. All these patients had nodular sclerosing Hodgkin's disease: Two had clinical stage IA presentations and 14 had clinical stage IIA. In two patients radiotherapy (35 Gy) was limited to the neck, three patients were treated definitively to the neck and mediastinum (40 Gy), and 11 patients received mantle irradiation (40 Gy). Four to five half-value layers of lead were used to shield the uterus during radiotherapy. The dose to the fetus was estimated individually in nine patients, using a combination of an Alderson-Rando and a water phantom. The estimated total dose to the mid-fetus ranged from 1.4 to 5.5 cGy for treatment with 6 MV photons, and from 10 to 13.6 cGy for Cobalt 60. All 16 patients subsequently delivered full-term, normal infants. Following delivery, all of the patients had further staging procedures; eight received additional treatment. Subsequently, the disease relapsed in four patients; two eventually died of Hodgkin's disease. The 10-year determinant and overall survival rates were 83% and 71%, respectively. Currently, all offspring are physically and mentally normal, and none has developed a malignancy. Radiotherapy is an appropriate initial treatment for supradiaphragmatic presentations of Hodgkin's disease during the second and third trimesters of pregnancy, provided special attention is paid to treatment and shielding techniques. The outcome for women treated with irradiation for clinical stage I and II Hodgkin's disease during pregnancy has not been shown to be adversely affected by pregnancy, and after the first 8 weeks of gestation, the risk to the fetus appears to be minimal.

NOVP and radiotherapy for early-staged Hodgkin's disease: an interim analysis.

Modern treatment plans for early staged Hodgkin's disease must focus on optimal disease-free survival results without laparotomy, minimal acute toxicity, and reduced long-term complications. We have treated 69 adult patients with stage I-II Hodgkin's disease, 40 of whom had bulky disease, B symptoms, or hilar disease, and 22 with stage III disease with 3 cycles of NOVP (Novantrone, vincristine, vinblastine, prednisone) and radiotherapy. Only patients with stage III1 disease involving the celiac axis without para-aortic or pelvic involvement, had to undergo laparotomy prior to treatment. Three patients did not respond to NOVP: two of these did not respond to MOPP or ABDIC, and two are currently without relapse following bone marrow transplant. With a median follow-up of 18 months, 62 with stage I-II and 19 with stage III remain without relapse, and 91 patients are alive. Tolerance to therapy was excellent with minimal nausea, myalgias, and alopecia. We conclude that this regimen for Hodgkin's disease provides good results for clinically staged I-III disease, but longer follow-up may demonstrate prognostic factors which will influence our results.

Therapy of relapsed or refractory low-grade follicular lymphomas: factors associated with complete remission, survival and time to treatment failure.

Patients with relapsed low-grade follicular lymphomas (LGFL) frequently respond to subsequent therapy and can have long survival, but are rarely cured. Factors associated with complete remission (CR) rate, length of survival, and time to treatment failure (TTF) after relapse are not well known. We assessed such factors by multivariate analysis in a retrospective review of 95 patients with relapsed LGFL treated with investigational chemotherapy regimens at our institution. The CR rate after therapy was 22%; the likelihood of achieving CR was inversely associated with the number of previous treatment failures (P less than 0.001) and serum LDH level (P less than 0.05). Both the presence of constitutional symptoms and a history of more than two previous treatment failures were associated with shortened survival and TTF. Hemoglobin level was also significantly associated with survival. Prognostic models for survival and TTF were derived to define patient groups with different projected outcomes after therapy for relapsed disease. The results of this study can be used to select patients for new investigational treatments and to evaluate the outcome of such therapies.

A proposal for a simple staging system for intermediate grade lymphoma and immunoblastic lymphoma based on the 'tumor score'.

A new staging system for intermediate grade lymphomas and immunoblastic lymphomas is described. This system is based on the tumor score which consists of assigning a point to each one of five variables that have been previously shown to have a high prognostic value. Ann Arbor stages III-IV, presence of bulky mass, elevation of B-2 microglobulin and LDH as well as presence of 'B' symptoms are the variables utilized in this system. When we applied this tumor score system to a population of 144 patients uniformly treated with CHOP/Bleo/CMED protocol, we observed that this system can accurately divide the population into two prognostic groups without an intermediate category. The first group is made up of those patients with a score of 0-2 points while the second group consists of patients with a score of > or = 3 points. The first group has a time-to-treatment failure (TTF) of 83% at three years in contrast to the second group whose TTF was 24%. If we compare this system with other commonly used systems in our institution, such as Ann Arbor, M.D. Anderson clinical staging system, and M.D. Anderson serological staging system, we observed that the tumor score system is not only more specific and sensitive than the others but also was capable of eliminating an intermediate risk group, thus facilitating therapeutic choices. This tumor score system is easy to apply and potentially reproducible in any institution.

Phase II trial of fludarabine phosphate in lymphoma: an effective new agent in low-grade lymphoma.

PURPOSE: In a phase II trial we investigated fludarabine phosphate (FAMP) as therapy for patients with relapsed lymphoma to determine its effectiveness and toxicity in this disease. PATIENTS AND METHODS: The 67 assessable patients had a median age of 56 years and had received a median of three chemotherapy regimens before treatment with FAMP. The starting dose was 25 mg/m2 administered intravenously over 30 minutes daily for 5 days every 3 to 4 weeks. RESULTS: High response rates were observed for follicular small cleaved-cell lymphoma (FSCCL) (62%), follicular mixed small- and large-cell lymphoma (80%), and follicular large-cell lymphoma (FLCL) (100%). Responses also occurred in small lymphocytic lymphoma (SLL) (33%), transformed lymphoma (33%), mycosis fungoides (40%), and Hodgkin's disease (25%). No responses were observed in other intermediate- or high-grade lymphomas (N = 20). Overall, there were five patients with a complete response, 23 patients with a partial response, and an overall response rate of 37%. Toxicity was primarily hematologic and infectious. No significant gastrointestinal, hepatic, renal, or neurologic toxicity occurred. CONCLUSIONS: We conclude that FAMP has major activity in follicular lymphoma. Fundamental research is needed to understand this differential efficacy in low-grade lymphoma yet lack of efficacy in intermediate- and high-grade lymphoma. Clinical investigations should be done using FAMP in varying dose schedules and in combination regimens.

Prognostic value of serum beta-2 microglobulin in low-grade lymphoma.

OBJECTIVE: To evaluate serum beta-2 microglobulin (beta-2M) and other prognostic indicators in previously untreated low-grade lymphoma. DESIGN: Cohort study of 80 patients with uniformly treated low-grade lymphoma, followed for a median of 21 months. These 80 patients, all of whom had serum beta-2M drawn within 2 weeks before starting therapy, were derived from a cohort of 119 previously untreated patients entered into one of three clinical trials. SETTING: Tertiary referral cancer center. PATIENTS: Eighty previously untreated stage I to IV patients (mean age, 55 years). INTERVENTION: Treatment was given according to Ann Arbor stage: Patients in stage IV were treated with CHOP-bleomycin and maintained on interferon therapy; those in stage III received CHOP-bleomycin and radiotherapy; and those in stages I and II received COP-bleomycin and radiotherapy. MEASUREMENTS: Outcome was determined by assessing complete remission rate and time to treatment failure. Univariate and multivariate analyses were used. RESULTS: The complete remission rate for patients with a beta-2M level of 3.0 mg/L or greater was 36% compared with 71% for those with a level of less than 3.0 mg/L. Using multivariate analysis that tested beta-2M as a continuous variable, it was selected as the most significant factor for complete response. The adjusted odds ratio was 0.285 (95% CI, 0.101 to 0.809). The Ann Arbor stage had marginal significance (adjusted odds ratio, 0.435; CI, 0.150 to 1.263). For time to treatment failure, beta-2M was the only variable retained in the multivariate model. At 42 months, no patient with a beta-2M level of 3.0 mg/L or greater was projected to be in remission as compared with 85% of patients with a beta-2M level of less than 3.0 mg/L. CONCLUSIONS: The serum beta-2M level is a good predictor of complete response and time to treatment failure. A larger number of patients should be studied to clarify the role of other potentially independent variables such as stage and age.

Stages I and II diffuse large cell lymphomas: prognostic factors and long-term results with CHOP-bleo and radiotherapy.

One hundred forty-seven patients with Ann Arbor stages I and II diffuse large cell lymphoma (DLCL) were treated with combination chemotherapy consisting of cyclophosphamide, doxyrubicin, prednisone, and low-dose bleomycin (CHOP-Bleo) and involved-field radiation (IF XRT) between 1974 and 1984. A complete remission (CR) was attained by 54 of 57 patients with stage I disease and by 78 of 90 patients with stage II disease. Thirty-five patients had relapsing disease that occurred within 3 years in 31. The overall 10-year survival rate, counting all deaths, for patients with stage I was 72% as compared with 43% for patients with stage II (P less than .01). Determinate survival rates, censoring eight unrelated deaths, were similar to the overall survival rates: 77% and 51%, respectively. A multivariate analysis identified three independent prognostic factors: age, tumor extent, and serum lactic dehydrogenase (LDH) level. When the combined effect of tumor extent and LDH level were taken into consideration in the analysis, three risk groups for survival were identified. The best group, which consists of patients with minimum tumor and normal LDH levels, had a 10-year determinate survival of 79%. Patients with extensive tumors and elevated LDH levels had the poorest survival rate of 44%. An intermediate-risk group with a determinant survival of 62% was composed of patients with either extensive tumors or elevated LDH levels. These differences demonstrate the need to develop different treatment strategies based on risk factors for survival for patients with apparently localized Ann Arbor stages I/II DLCL.

Stage I-II low-grade lymphomas: a prospective trial of combination chemotherapy and radiotherapy.

Between 1984-1989, 44 patients with stage I-II low grade lymphoma were treated prospectively with sequential chemotherapy and involved-field radiotherapy. The chemotherapy was cyclophosphamide, vincristine, prednisone, and bleomycin (COP-Bleo); doxorubicin was included (CHOP-Bleo) for patients with adverse prognostic features (high LDH; extranodal sites; bulky nodes). Of the 44 patients, 37 had measurable disease and all have responded. With a median follow-up of 32 months, the 5-year survival and failure-free survival were 89% and 74%, respectively. Compared to past experience with involved-field radiotherapy alone, the failure-free survival is significantly better with COP-Bleo plus radiotherapy. The potentially cured fraction has risen from 40% to 74%.

Two cycles of MOPP and radiotherapy: effective treatment for stage IIIA and IIIB Hodgkin's disease.

Two cycles of MOPP (mechlorethamine, vincristine (Oncovin), procarbazine, prednisone) and radiotherapy were used to treat 197 patients with stage III Hodgkin's disease. Prior to 1980, radiotherapy was delivered to the mantle, abdomen and pelvis; thereafter, pelvic irradiation was deleted for patients with stage III1 disease. Complete remission rates for IIIA and IIIB presentations were 91% and 89%. The 10-year freedom from tumor mortality (FTM) rate for all patients was 81%; for IIIA, it was 87% and for IIIB, it was 72%. Results were not significantly affected by gender, age, pathology, or deletion of pelvic radiotherapy. However, a subgroup of 28 patients with a tumor burden that included pelvic disease who also had B symptoms was identified as having a poor prognosis. Their FTM was 43%, compared with 87% for all other patients combined (P = 0.002). Based on this analysis, we conclude that limited chemotherapy in combination with radiation therapy can yield results similar to programs that use more chemotherapy for all patients with IIIA disease and for most patients with stage IIIB. However, patients with tumor burdens which include pelvic disease and B symptoms require a different approach.
