Comparison of total nodal irradiation versus combined sequence of mantle irradiation with mechlorethamine, vincristine, procarbazine, and prednisone in clinical stages I and II Hodgkin's disease: experience of the European Organization for Research and Treatment of Cancer

The H5 study of supradiaphragmatic Hodgkin's disease in clinical stages I-II consisted of two controlled trials adapted to patients considered to have either favorable or unfavorable characteristics, based on prognostic factors identified in two former studies by the European Organization for Research and Treatment of Cancer. Of 494 patients, 257 who were classified as having unfavorable prognosis qualified for the more intensive treatment and consequently were spared a staging laparotomy. They were randomized either to total nodal irradiation (TNI) (132 patients) or to treatment with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) alternated with mantle irradiation (MOPP X 3-mantle irradiation-MOPP X 3; 3M) (125 patients). In complete responders (96%), the 6-year relapse-free survival was 77% in the TNI arm and 91% in the 3M arm (P = .02). Relapses in the initially involved and irradiated mantle area were less frequent in patients started on MOPP. The 6-year actuarial total survival (TS) (TNI, 82%, and 3M, 89%; P = .05) appeared to favor the 3M arm, but this difference disappeared when patients dying from causes unrelated to cancer were excluded from analysis. In men less than or equal to 40 years old, there was no difference in relapse-free survival, freedom from disease progression, or TS between the groups receiving TNI and 3M. Thus, TNI is a short and appealing treatment, especially because it preserves fertility. The same observation was true in women less than or equal to 40 years old. In addition, even irradiation less than TNI, which is meant to spare the ovaries, provided a TS similar to that for 3M.     

The EORTC treatment of early stages of Hodgkin's disease: the role of radiotherapy

Since 1964, the European Organisation for Research and Treatment of Cancer has conducted three subsequent clinical trials on clinical Stages (CS) I + II Hodgkin's disease (HD) in which 1059 patients have been entered. The first trial compared regional radiotherapy (RT) with mantle field or inverted Y, versus the same RT followed by a weekly injection of vinblastine for 2 years. The relapse free survival (RFS) and overall survival (S) were higher in patients treated by RT and chemotherapy (CT). This benefit, however, was significant only in patients with a mixed cellularity histologic type. The second trial compared the therapeutic efficacy of splenic irradiation versus splenectomy and found that in both arms, RFS and S were identical. Moreover, it was found that splenic involvement was correlated with an increased incidence of relapse in extranodal sites and in non irradiated lymphatic areas. In this trial, CT was given only to patients with poor histologic types, mixed cellularity or lymphocytic depletion. In the third trial, staging laparotomy was performed only to further delineate a good prognostic group which could be treated by RT alone. In this limited treatment group, there was no difference in RFS and S between mantle field and mantle field + para-aortic RT. In the extensive treatment group, total nodal irradiation (TNI) was compared with RT + MOPP. The RFS was slightly lower in the TNI arm, but there was no significant difference in S. The data of the 3 trials underline the importance of prognostic factors in the choice of optimal treatment and show that their significance depends upon the type of treatment. Multivariate statistical analyses showed that the main prognostic factors, which can help to identify the subsets of patients who can be treated by RT alone, are (1) systemic symptoms and elevated erythrocyte sedimentation rate (ESR), (2) the number of involved lymphatic areas, and (3) staging laparotomy. Extended RT (mantle + para-aortic + spleen treatment) gives satisfactory results in patients without systemic symptoms and/or elevated ESR and one or two involved sites, whereas TNI or combined modality treatment becomes mandatory for patients with 3 or more involved sites or splenic involvement and/or systemic symptoms. With proper adjustment of the irradiated volume, a very large proportion of CS I + II patients can be best treated by RT alone.     

Increased risk of secondary acute nonlymphocytic leukemia after extended-field radiation therapy combined with MOPP chemotherapy for Hodgkin's disease

The purpose of this study was to evaluate the influence of the number of mechlorethamine, vincristine, procarbazine, and prednisolone (MOPP) cycles and the extent of irradiation on the risk of secondary acute nonlymphocytic leukemia (SANLL) after a single combined treatment for Hodgkin's disease (HD). Between April 1972 and May 1980, 462 patients with HD clinical stage (CS) I, II, and III were prospectively treated with three or six cycles of MOPP and supra- and/or infradiaphragmatic irradiation (40 Gy). Four hundred forty-one patients achieved complete remission (CR). By January 1988, 237 patients had been followed-up in first CR for at least 10 years. Ten patients developed SANLL between the 34th and 123rd month of CR. The 15-year SANLL risk is 3.5% +/- 2.7%. Cox's stepwise regression analysis performed with all initial and treatment covariates (sex, age, histology, splenectomy, MOPP chemotherapy, and irradiation extent) showed that the only significant explanatory variable of SANLL risk was the irradiation extent (P less than .002). Using the log-rank test, SANLL risk ranged from 2.2% for supradiaphragmatic irradiation alone to 9.1% for subtotal (STNI) or total nodal irradiation (TNI) (P less than .001). These results strongly suggest that extended high-dose irradiation and MOPP chemotherapy should not be combined for the treatment of HD.     

Stages IIB and IIIB Hodgkin's disease. Results of combined modality treatment.

Between April 1969, and December 1974, 23 IIB and 26 IIIB surgically staged patients with Hodgkin's disease were treated at the Joint Center for Radiation Therapy. Stage IIB patients received either mantle and para-aortic-splenic pedicle, or total modal irradiation (TNI) alone or with the addition of combination chemotherapy. Relapse-free survival is 83% and overall survival 88%. Eleven patients received combination chemotherapy in addition to mantle and para-aortic irradiation, and both the relapse-free and overall survival are 100%. Of the stage IIIB patients, seven received TNI alone with four relapses, and 19 were treated with TNI and MOPP with two relapses. These relapse rates are significantly different (p less than 0.05). The relapse-free and overall survival for all stage IIIB patients is 66% and 84% respectively. These data imply that irradiation alone is not adequate treatment for stage IIIB Hodgkin's disease, and that with the addition of combination chemotherapy both the disease-free and overall survival is similar to that of early stage Hodgkin's disease without systemic symptoms. The ideal management of stage IIB Hodgkin's disease is less certain; it is our plan to study the efficacy of combined modality treatment.     

206例成人早期霍奇金病的放射治疗

目的：探讨成人早期（Ⅰ、Ⅱ期）霍奇金病（HD）放射治疗野的规范使用。方法：回顾性分析1984年1月至1997年12月中国肿瘤收治的206例初治的膈上型早期霍奇金病成人患者（≥15岁）,其中130例单纯放射治疗（称为单放组,76例行放射治疗＋化疗（称为综合治疗组）。放射治疗采用累及野（IF）照射7例、斗蓬野（MF）照射34例、次全淋巴结照射（STNI）140例、全淋巴结照射（TNI）25例。Kaplan-Meier法行生存分析、Logrank法行显著性检验。结果：①全组5、10年总生存率分别为85．1％和73．2％,5、10年无瘤生存率分别为68．0％和63．6％。②单放组中接受MF、STNI和TNI照射的5年生存率分别为69．2％、93．3％、和94．4％;5年无瘤生存率分别为54．2％、79．2％、79．9％（P＜0．05）。③综合治疗组中接受IF（MF）照射和STNI（TNI）和5年总生存率分别为75．7％和90．6％,5年无瘤生存率分别为43．1％,和73．3％,P＜0．05）。结论：除了少数预后极好的IA期患者可给予单纯MF照射外,其它期别的患者在采用单纯放射治疗时宜选用STNI,盲目缩小放射治疗野将会导致无瘤生存率甚至总生存率的下降,预后不利的患者应给予放射治疗＋化疗综合治疗。     

Stage III Hodgkin's disease: improved survival with combined modality therapy as compared with radiation therapy alone

This is a retrospective analysis of 120 patients with pathologically stage IIIA and IIIB Hodgkin's disease treated from April 1969 to December 1982. The median follow-up was 108 months. Treatment consisted of radiation therapy (RT) alone in 54 patients and combined radiation therapy and MOPP (nitrogen mustard, vincristine, procarbazine, prednisone) chemotherapy (CMT) in 66 patients. Stage III patients treated with CMT have an improved actuarial 12-year survival as compared with patients treated with RT alone with MOPP reserved for relapse (80% v 64%; P = .026). The 12-year actuarial freedom from first relapse by treatment for stage III patients is 83% and 40%, respectively (P less than .0001). Improved survivals following combined modality therapy are seen for the following subgroups of stage III patients: stage III2, 66% (CMT) v 44% (total nodal irradiation; TNI), P = .04; stage III1, 97% (CMT) v 73% (TNI), P = .05; stage III mixed cellularity or lymphocyte depletion histology, 94% (CMT) v 65% (TNI), P = .007; and stage III extensive splenic involvement, 77% (CMT) v 58% (TNI), P = .02. These survival differences are not seen in patients with nodular sclerosis or lymphocyte predominance histology or in patients with minimal splenic involvement. These data indicate that the initial use of CMT in stage III Hodgkin's disease results in an improved survival as compared with initial treatment with RT with MOPP reserved for relapse. Patients with limited Stage IIIA disease may still be candidates for radiation therapy alone.     

Extended-field radiotherapy is superior to MOPP chemotherapy for the treatment of pathologic stage I-IIA Hodgkin's disease: eight-year update of an Italian prospective randomized study.

PURPOSE: To compare the effectiveness of chemotherapy (CHT) with extended-field radiotherapy (RT) in the treatment of early-stage Hodgkin's disease (ESHD), we report an 8-year updated analysis of a study in which treatment with six cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) CHT was randomly compared with extended-field RT. PATIENTS AND METHODS: From August 1979 to December 1982, 89 adult patients with pathologic stage I-IIA Hodgkin's disease (HD) were randomly allocated to receive either RT with mantle field followed by periaortic irradiation (n = 45) or six monthly courses of MOPP CHT (n = 44). RESULTS: All patients in the RT arm and 40 of 44 in the CHT arm achieved complete remission. Twelve relapses occurred in each group. Eight patients treated with MOPP and two of the RT arm died of HD. Three other patients of the CHT group died because of a second cancer. With a median follow-up greater than 8 years, the overall survival rate is significantly higher in the RT than in the CHT group (93% v 56%; P less than .001), whereas the rates of freedom from progression and relapse-free survival (RFS) were similar in the two groups (76% v 64% and 70% v 71%, respectively). Of the 12 patients relapsing after RT, 11 (92%) achieved a second CR, compared with only six of the 12 (50%) in the MOPP group. Analysis of the response rate to salvage treatments showed that the type of relapse in the MOPP group was a prognostic indicator for the achievement of a second CR, whereas in the RT group, a second CR was obtained regardless of the characteristics of the relapses. At 80 months, the probability of survival of relapsing patients calculated from time of relapse was 85% and 15% in the RT and CHT groups, respectively (P = .02). CONCLUSION: We conclude that RT alone is the treatment of choice for adult patients with ESHD with favorable prognostic factors.     

An evaluation of total nodal irradiation as treatment for stage III A Hodgkin's disease.

Between April 1969 and December 1974, 37 patients with surgically staged III A Hodgkin's disease were treated with total nodal irradiation (TNI). Their probability of relapse-free survival at 7 years is 51% and overall survival 82% with the majority of patients remaining disease free after retreatment with MOPP (10 of 16). In contrast, 21 stage III B patients treated with TNI and MOPP chemotherapy over the same time period have a relapse-free survival of 74% and overall survival of 91%. Because of superior results in treating stage III B patients with combined modality treatment, we fell that a relapse-free survival of 51% may not justify continuation of TNI as the only modality of treatment for patients with stage III A disease, and we have initiated a trial of combined radiation therapy and MOPP chemotherapy in these patients. The most effective treatment of stage III A Hodgkin's disease, however, remains uncertain and depends both on the ultimate risk of combined modality treatment and the success of retreatment following relapse after radiation.     

Evaluation of therapeutic modalities in the control of Hodgkin's disease

The results achieved in three different studies carried out on patients affected by Hodgkin's disease are discussed. In study No. 1, 58 patients with pathological Stage I-II were treated with only a "Mantle" field irradiation. The complete remission (CR) rate was 98% with an actuarial overall survival of 90%, and a median of follow-up of 80 months. Thirty-one percent of patients relapsed. In study No. 2, 42 patients were randomly allocated to receive only MOPP chemotherapy versus extended field irradiation; CR rate was 68 and 95%, respectively (p less than 0.05). The overall survival rate was 100% in the radiotherapy group and 82% in the MOPP group. No relapses have been observed in patients treated with MOPP. In study No. 3, 218 patients affected by advanced Stage HD were randomly treated with 6 cycles of MOPP chemotherapy versus 6 cycles of ABVD chemotherapy. In the MOPP group the CR rate, the relapse-free survival rate (RFS), and overall survival (OS) rates at 60 months were 77, 68, and 76% respectively, whereas, in the ABVD group the CR, the RFS, and OS rates at 60 months were 75, 77 and 80% respectively, (p less than 0.05). These data and statistical comparisons are analyzed.     

Stages I--III Hodgkin's disease in children: results of staging and treatment.

Fifty-two children with clinical stages I-III Hodgkin's disease were evaluated for disease extent between April 1969 and March 1975. All underwent laparotomy and splenectomy. Two patients with liver involvement were excluded. Thirty of 31 patients with pathologically staged IA-IIA disease have been continuous complete remission after mantle and para-aortic irradiation. There have been no extensions into the untreated pelvis. Fourteen of 15 patients with pathologic stages IIB and IIIB disease show no evidence of relapse after TNI and MOPP. Three of four patients with stage IIIA disease developed nodal relapse after irradiation; all are alive without evidence of disease after re-irradiation (3) and MOPP (2). Thus 45 of 50 patients (90%) have remained continuously free of disease after completion of the planned treatment, and overall 49 of 50 (98%) are alive, without evidence of disease. Such results justify continuation of our staging and treatment philosophy in children with Hodgkin's disease.     

The adjuvant role of two cycles of MOPP and low-dose lung irradiation in stage IA through IIB Hodgkin's disease: preliminary results

Fifty-eight laparotomy-staged I and II patients with upper torso presentations of Hodgkin's disease and 8 patients with lymphangiogram-staged lower torso disease were treated with radiotherapy alone or with 2 cycles of MOPP and radiotherapy. Patients with upper torso disease with either no mediastinal or only small mediastinal disease without hilar involvement and with no "B" symptoms were treated with mantle radiotherapy alone. Patients with large mediastinal masses or hilar disease were treated with 2 cycles of MOPP followed by definitive mantle irradiation and low dose lung irradiation. Those for whom "B" symptoms were the only adverse prognostic feature received 2 cycles of MOPP and mantle radiotherapy. Patients with lower torso disease were treated with radiotherapy alone if the disease was limited to the pelvis. Those with more extensive disease received 2 cycles of MOPP prior to radiotherapy. The 4-year survival for all 66 patients was 97%. The corresponding disease-free and freedom from second relapse figures were 77% and 92%. Survival for the patients with unfavorable presentations who received 2 cycles of MOPP and radiotherapy was 100%. It was 92% for the group with favorable presentations who were treated with radiotherapy only.     

Treatment of pathologically staged IIIA Hodgkin's disease

We have reviewed the records of 37 patients with pathologically staged IIIA Hodgkin's disease, treated from 1970 to 1982. Twenty patients were staged IIIA1 and 17 staged IIIA2. Treatment consisted of total nodal irradiation in 33 patients (eight of whom received adjuvant MOPP), and mantle plus para-aortic irradiation in four patients (all of whom received adjuvant MOPP). Five-year relapse-free survival (RFS) in patients without splenic involvement was 77% versus 49% for those with splenic involvement (p = 0.43). Five-year RFS in patients treated with irradiation and chemotherapy (RT/CT) was 76% vs. 47% for patients treated with irradiation alone (p = 0.12). RFS was not influenced by sex, mediastinal involvement by tumor, or anatomic substage. Overall survival (corrected for deaths due to intercurrent disease) for the entire group of patients was 92% at 5 years and 87% at 10 years. Sex, mediastinal or splenic involvement by tumor, therapy (RT vs. RT/CT), or anatomic substage did not significantly influence survival. We currently recommend RT/CT only for those patients with extensive splenic involvement and/or Stage IIIA2 disease. We feel that the poor prognosis of these patients justifies the use of RT/CT and its risk of second malignancies.     

Long-term results of a randomised trial of involved field radiotherapy vs extended field radiotherapy in stage I and II Hodgkin lymphoma

Involved field (IF) radiation was compared with extended field (EF) radiation in Hodgkin lymphoma (HL) to ascertain whether reduced radiation fields would reduce the late sequelae of radiation without compromising disease control and survival. A total of 603 patients with stage I or II HL were entered into this trial; laparotomy was carried out in 380 (63%) patients. Stage I or IIA disease patients were randomised to receive IF or EF comprising a mantle or inverted Y fields alone. Stage I and IIB patients were randomised between mantle or inverted Y fields and total nodal irradiation (TNI). The dose was 35 Gy to uninvolved sites and 40 Gy to involved sites. The median followup of surviving patients was 25.2 years with only 3.3% lost to follow-up. The treatment failure rate at 25 years in stage IA and IIA was 44% after EF and 54% after IF (P = 0.01); in stage I and IIB this was 80% (EF) and 82% (TNI) at 25 years. No difference in overall survival between the randomised groups was seen. The incidence of second malignancies was 21% after IF and 20% after EF with a slight excess of lung cancer in the EF group. No significant differences in the causes of death between the randomised arms have emerged. In conclusion, IF radiotherapy for stage I and IIA HL results in a 11% greater risk of relapse compared with EF but has no effect on overall survival, risk of second malignancy or cause of death at 25 years.     

Hodgkin's disease in children. Results of therapy in a mixed group of 178 clinical and pathologically staged patients over 13 years

One hundred seventy-eight previously untreated children with biopsy-proven Hodgkin's disease of clinical Stages I and II were treated and followed between 1965 and 1978. Staging laparotomy was performed in 30 patients. Ninety-four percent of the patients obtained a complete remission; 24 patients have died. The actuarial survival rate for all patients was 90% at 5 years, and 81% at 10 years. The disease-free survival rate was 69% at 5 years, and 65% at 10 years. When nitrogen mustard, vincristine, procarbazine, and prednisone (MOPP) chemotherapy was added to either extended field or involved field irradiation, the relapse rate was significantly decreased as compared with the protocols without MOPP and prophylactic para-aortic irradiation. The authors believe that surgical staging may not be necessary as splenic involvement may be treated in some patients by MOPP chemotherapy alone or in association with splenic paraaortic radiotherapy. However, the side effects of MOPP need further study by other chemotherapy programs.     

ABVD plus subtotal nodal versus involved-field radiotherapy in early-stage Hodgkin's disease: long-term results.

PURPOSE: Radiation therapy (RT) alone can cure more than 80% of all patients with pathologic stage IA, IB, and IIA Hodgkin's disease, but some prognostic factors unfavorably affect treatment outcome. Combined-modality approaches improved results compared with RT, but the optimal extent of RT fields when combined with chemotherapy warranted additional evaluation. PATIENTS AND METHODS: In February 1990, we activated a prospective trial in patients with early, clinically staged Hodgkin's disease to assess efficacy and tolerability of four cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by either subtotal nodal plus spleen irradiation (STNI) or involved-field radiotherapy (IFRT). RESULTS: Main patient characteristics were fairly well balanced between the two arms. Complete remission was achieved in 100% and in 97% of patients, respectively. The 12-year freedom from progression rates were 93% (95% CI, 83% to 100%) after ABVD and STNI, and 94% (95% CI, 88% to 100%) after ABVD and IFRT, whereas the figures for overall survival were 96% (95% CI, 91% to 100%) and 94% (95% CI, 89% to 100%), respectively. Apart from three patients who developed second malignancies in the STNI arm, treatment-related morbidities were mild. CONCLUSION: Present long-term findings suggest that, after four cycles of ABVD, IFRT can achieve a worthwhile outcome. The limited size of our patient sample, however, had no adequate statistical power to test for noninferiority of IFRT versus STNI. Despite this, ABVD followed by IFRT can be considered an effective and safe modality in early Hodgkin's disease with both favorable and unfavorable presentation.     

Long-term results in patients with low-grade nodular non-Hodgkin's lymphoma. A randomized trial comparing chemotherapy plus radiotherapy with chemotherapy alone

One hundred and eighteen patients with nodular non-Hodgkin's lymphoma were randomized to receive either chemotherapy alone or chemotherapy plus radiotherapy (total nodal or involved field irradiation). Although the complete remission rate was similar in the three programs (about 90%) the relapse-free survival rate (RFS) among patients with complete remission was significantly higher in the groups treated with chemotherapy plus radiotherapy than among those treated with chemotherapy alone. The 7-year RFS in the groups treated with total node irradiation and involved field irradiation was 71% and 66% respectively, compared to only 33% in the group treated by chemotherapy alone (p less than 0.01). The results suggest that combined chemoradiotherapy may achieve complete long-term remission and potential cure in more than 60% of patients with nodular low-grade non-Hodgkin's lymphoma. Toxicity was moderate in all three arms. Bulky disease and a high level of lactic dehydrogenase were associated with a poor prognosis.     

The impact of pelvic recurrence and elective pelvic irradiation on survival and treatment morbidity in early-stage Hodgkin's disease

A retrospective analysis of patients with supradiaphragmatic Stage I-II Hodgkin's disease was performed to assess the impact of pelvic recurrence and elective pelvic irradiation on survival and treatment morbidity. One hundred twenty patients were treated with radiotherapy (RT) alone; 38 received total nodal (including pelvic) irradiation (TNI), 63 received modified total nodal (excluding pelvic) irradiation (MTNI), and 19 received involved-field or mantle irradiation only (less than MTNI). Thirty-three patients received combined-modality therapy. In laparotomy-staged (PS) patients treated with RT alone, the overall treatment failure rate was 13% after TNI, 24% after MTNI, and 43% after less than MTNI. The pelvic failure rate in PS patients was 0% after TNI, 9% after MTNI, and 29% after less than MTNI. Cause-specific deaths in patients treated with RT alone occurred in 10% following less than MTNI, 13% following MTNI, and 10% following TNI. Cause-specific deaths due to pelvic failure in patients treated with RT alone occurred in 5% following IF and 6% following MTNI, and also occurred in 7% of patients receiving combined-modality therapy. The potential disadvantages of elective pelvic irradiation in early-stage Hodgkin's disease include compromise of future tolerance of chemotherapy in the event of treatment failure, and infertility. Gonadal function was assessed in 67 patients less than 35 years old at the time of treatment. Compromise of gonadal function was correlated with the lack of special testicular shielding during pelvic irradiation and chemotherapy in the male, and with no oophoropexy before pelvic irradiation in the female. Twelve of 26 patients with recurrence after either less than MTNI or MTNI, with or without chemotherapy, were alive and without evidence of disease at greater than 2 years after completing salvage therapy, compared with 7 of 11 patients with recurrence after TNI.     

MOPP chemotherapy plus irradiation for Hodgkin's disease, stages IA to IIIB. Long-term results of the prospective trial H72 (1972-1976, 334 patients)

From April 1972 to December 1976, 334 patients with Hodgkin's disease, CS IA-IIIB, were prospectively treated with combined chemotherapy and radiation. The 166 stages IA and II2A were clinically staged only; the 168 other patients were randomized to clinical or pathological staging. All patients received 3 or 6 cycles of MOPP followed by Mantle field with or without mediastinal irradiation and/or inverted Y or lumbo-aortic field according to initial stage, presentation and protocol. At completion of therapy, 317 patients were in complete remission. Twenty-six patients relapsed and 43 died including 5 with leukemia and 6 with infection. Overall 12-year survival and relapse-free rates are 86.6 +/- 3.08 per cent and 91.5 +/- 3.2 per cent respectively (IA: 95.3 and 95.3 per cent; IIA: 87.8 and 92.1 per cent; IIIA: 83.3 and 100 per cent; IB, IIB: 81.7 and 89.2 per cent; IIIB: 67.8 and 73.7 per cent). The randomized comparison between clinical staging plus 6 cycles of MOPP and laparotomy staging plus 3 cycles of MOPP in final stage II3+A, IB, IIB patients showed no significant 12-year survival differences (90.8 versus 85.6 per cent). With this combined modality treatment policy, high survival rates are obtained using only 3 cycles of MOPP and radiotherapy in CS IA, II2A and in PS II3+, IB, IIB. Laparotomy staging may be unnecessary if 6 cycles of MOPP are employed before irradiation in CS IIA, IB, IIB disease and if 3 cycles of MOPP are followed by irradiation in CSIA and II2A disease. Mediastinal irradiation can be avoided in patients with supradiaphragmatic disease without mediastinal involvement.     

Phase III study comparing standard radiotherapy with or without weekly oxaliplatin in treatment of locoregionally advanced nasopharyngeal carcinoma: preliminary results.

PURPOSE: A prospective, randomized, phase III study was performed to evaluate the feasibility and efficacy of concurrent weekly oxaliplatin with radiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS: From January 2001 to January 2003, 115 patients with locoregionally advanced NPC were randomly assigned to either radiotherapy (RT) alone (56 patients) or concurrent chemoradiotherapy (CCRT; 59 patients). All patient characteristics were well balanced in both arms. CCRT with oxaliplatin 70 mg/m2 weekly was administered for six doses from the first day of RT. RESULTS: All patients were eligible for toxicity and response analysis. Compliance with the protocol treatment was excellent, with 97% of patients completing all planned doses of oxaliplatin, and a lack of high-grade toxicity was observed. After a median follow-up time of 24 months, there was a significant difference in overall survival (OS), relapse-free survival (RFS), and metastasis-free survival (MFS) in favor of the CCRT arm. The 2-year OS rates were 100% for the CCRT arm and 77% for the RT arm (P = .01). The 2-year MFS rates were 92% for the CCRT arm and 80% for the RT arm (P = .02). The 2-year RFS rates were 96% for the CCRT arm and 83% for the RT arm (P = .02). CONCLUSION: CCRT with weekly oxaliplatin is feasible and improves OS, MFS, and RFS rates in patients with locoregionally advanced NPC. Therefore, further randomized trials including oxaliplatin are warranted.     

Reduction of fatal complications from combined modality therapy in Hodgkin's disease

A total of 464 pathologically staged IA through IIIB Hodgkin's disease patients were evaluated for the risk of developing acute nonlymphocytic leukemia, non-Hodgkin's lymphoma, or a fatal infection after treatment with radiation therapy (RT) alone, initial combined radiation therapy and chemotherapy (CMT), or RT with MOPP administered at relapse. Patients received a standard six cycles of MOPP, and additional maintenance chemotherapy was not administered. Patients receiving total nodal irradiation (TNI) and MOPP chemotherapy have an 11.9% actuarial risk of developing a fatal complication at ten years, as compared to a 0.8% risk for lesser field irradiation and MOPP (P = .005). The risk with RT alone is 0.6%. Patients 40 years of age or older have a greater risk for complications. These data report a low risk for fatal complication with CMT when less than TNI is administered and when maintenance chemotherapy is not used.
