Patients' expectations and experiences of rehabilitation following lung transplantation.

INTRODUCTION: Exercise rehabilitation is a key element of care following lung transplantation; however, little is known about the patients' experience of rehabilitation, or whether it meets the needs of this complex patient group. This qualitative study explored patients' expectations of a supervised exercise rehabilitation program following lung transplantation. METHODS: Participants undertook two semi-structured interviews, one before and one after the rehabilitation program. Interviews were digitally recorded, and themes were developed using line-by-line iterative thematic analysis and grounded theory. RESULTS: Eighteen adults (11 females) with mean age of 52 participated in a mean of 26 sessions of exercise training. Themes were (i) desire for normalcy including resuming family roles and performing everyday activities; (ii) the importance of rehabilitation as the mechanism for how this transformation occurred; (iii) the benefits of exercising in a group setting; and (iv) the limitations on rehabilitation that were imposed by comorbidities, either existing pre-transplant or occurring as a postoperative sequelae. CONCLUSION: Post-transplant exercise rehabilitation was perceived as a highly valuable tool that assisted recipients to return to "normal life." Group exercise was motivational, offered peer support, and therefore was advantageous to assist patients to achieve their desired physical performance level following transplantation.

Long-term results with radiotherapy for Stage I-II follicular lymphomas.

PURPOSE: To analyze the long-term results with radiotherapy (RT) for early-stage, low-grade follicular lymphomas. METHODS AND MATERIALS: From 1960 to 1988, 80 patients with Stage I (n = 33) or II (n = 47), World Health Organization Grade 1 (n = 50) or 2 (n = 30) follicular lymphoma were treated with RT. The lymph nodes or spleen were involved in 97% of cases. The maximal tumor sizes ranged from 0.5 to 11.0 cm (median 2.0). The RT fields encompassed only the involved Ann Arbor nodal region (involved-field RT) in 9% of the patients. The fields also included 1-3 adjacent, grossly uninvolved nodal regions (regional RT) in 54% of patients but were smaller than mantle or whole abdominopelvic fields. Mantle or whole abdominopelvic fields encompassing up to 6 grossly uninvolved regions (extended-field RT) were used in the remaining 37% of patients. The total RT doses ranged from 26.2 to 50.0 Gy given in daily 1.0-3.0-Gy fractions. RESULTS: The follow-up of the surviving patients ranged from 3.5 to 28.7 years (median 19.0). No recurrences were found >17.0 years after RT, with 13 patients free of disease at their last follow-up visit 17.6-25.0 years after treatment. In 58% of cases, death was not from follicular lymphoma. The 15-year local control rate was 100% for 44 lymphomas <3.0 cm treated with only 27.8-30.8 Gy (median 30.0 in 20 fractions). Progression-free survival was affected by the maximal tumor size at the start of RT (15-year rate 49% vs. 29% for lymphomas <3.0 cm vs. > or =3.0 cm, respectively, p = 0.04) and Ann Arbor stage (15-year rate 66% vs. 26% for Stages I and II, respectively, p = 0.006). Ann Arbor stage also affected the cause-specific survival (15-year rate 87% vs. 54% for Stages I and II, respectively, p = 0.01). No significant difference was found in overall survival between those treated with extended-field RT and those treated with involved-field RT or regional RT (15-year rate 49% and 40%, respectively, p = 0.51). The 15-year incidence rate of Grade 3 or greater late complications according to the Subjective, Objective, Management, and Analytical scale in patients treated with 26.2-30.8 Gy vs. 30.9-50.0 Gy was 0% and 6%, respectively. CONCLUSIONS: RT can cure approximately one half of Stage I and one quarter of Stage II, World Health Organization Grade 1 or 2 follicular lymphomas. Follicular lymphomas <3.0 cm can be controlled locally with doses of 27.8-30.8 Gy, and there is a trend toward a higher incidence of late complications with doses of >30.8 Gy. Doses of 25-30 Gy delivered in 15-20 fractions should be examined prospectively in patients with follicular lymphomas of <3.0 cm.

Recovery of sperm production following radiation therapy for Hodgkin's disease after induction chemotherapy with mitoxantrone, vincristine, vinblastine, and prednisone (NOVP).

PURPOSE: The effect on human male fertility of radiotherapy following chemotherapy for the treatment of Hodgkin's disease (HD) is unknown. The impact of radiation therapy, given after mitoxantrone, vincristine, vinblastine, and prednisone (NOVP) chemotherapy, on sperm production is the focus of this study. PATIENTS: Serial semen analyses were performed on 34 patients with HD Stages I-III before NOVP chemotherapy, after chemotherapy prior to radiation, and after radiation therapy. The most inferior radiation portals for patients were: mantle, 1 patient; paraaortic-spleen, 3 patients; upper abdomen, 24 patients; abdominal spade, 4 patients; and pelvic, 2 patients. Testicular radiation dose measurements were available for 20 of these patients. RESULTS: Before the start of radiation, 90% of patients were normospermic. The magnitude of the decline in sperm counts was related to the measured testicular dose and/or radiation fields employed. The minimum postradiotherapy counts, expressed as a fraction of pretreatment counts, for the various treatment groups are as follows: paraaortic-spleen, 20%; upper abdomen, testicular dose < 30 cGy, 4%; upper abdomen, testicular dose 30-39 cGy, 0.9%; abdominal spade, 0.02%; and pelvis, 0%. The time to nadir of sperm counts averaged 4.5 months. Recovery to normospermic levels occurred in 96% of patients, with most recovering to that level within 18 months. CONCLUSION: The effect of radiation following NOVP chemotherapy on sperm counts was no greater than would be expected with radiation therapy alone. In most patients, sperm counts recovered to levels compatible with normal fertility.

Validation of an XML-based process to automatically web-enable clinical practice guidelines: experience with the smoking cessation guideline.

OBJECTIVES: To validate the ease by which a Clinical Practice Guideline (CPG) can be web-enabled using an XML-based semi-automated process. DESIGN AND IMPLEMENTATION: An XML DTD for Clinical Practice Guidelines and an MS Word authoring template were created in an earlier project. We took an existing guideline, Bedside Smoking Cessation Intervention, placed it into the MS Word template, converted it into XML, and then to HTML for deployment over the Kaiser Permanent intranet. CONCLUSIONS: We were able to use the MS Word authoring template and automatically generate both an XML representation of our guideline, and an HTML representation, which we have deployed on our intranet. The Bedside Smoking Cessation Intervention guideline was automatically merged into the online guidelines collection. Placing it on our intranet allowed for rapid and easy access by physicians and other health care providers throughout the Kaiser Permanente Medical Care Program.

Primary non-Hodgkin lymphoma of the small bowel.

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.

Hodgkin's disease with lymphocyte predominance: long-term results based on current histopathologic criteria.

PURPOSE: To define the disease course, therapeutic strategies, patterns and rates of relapse and causes of death for patients with Hodgkin's disease with lymphocyte predominance (LPHD) and to assess prognostic factors including nodular and diffuse histologic patterns. PATIENTS AND METHODS: The records of all previously untreated patients with LPHD who received initial treatment at the University of Texas M. D. Anderson Cancer Center (UTMDACC) from 1960 through 1992 were reviewed. Clinical and histopathologic characteristics, specifically nodular and diffuse LPHD, and treatment groups were assessed by overall and relapse-free survival, patterns of relapse, and causes of death. RESULTS: Of 70 patients, 58 (83%) had nodular LPHD and 12 (17%) had a diffuse pattern: clinical characteristics were similar between the two subtypes. The median age of all patients was 25 years, 79% were male, 96% presented with stage I or II disease and 93% were free of B symptoms. Laparotomy (23 patients) failed to upstage any patient with a negative lymphogram. With a median follow-up of 12.3 years for alive patients, 19 (27%) patients have relapsed. All 3 relapses among the patients with diffuse subtype occurred within 3 years while 9 of 16 relapses occurred after 5 years with nodular subtype. However, we did not detect any statistically significant difference in relapse free survival or survival between the subtypes in our patient population. There was some suggestion that patients aged 40 and older experienced shorter survival; no other pretreatment characteristics were noted to be associated with relapse free survival or survival. Though there were no relapses within the radiation fields, no effect of extent of radiation therapy on relapse rate was observed. Thirteen (19%) patients have died, 6 (8.6%) of whom succumbed to LPHD. Two patients developed diffuse large cell lymphoma. CONCLUSIONS: Patients with LPHD usually present with localized and asymptomatic disease. Laparotomy is unnecessary if the lymphogram is negative. Nodular histology occurred in the majority of patients. Though all relapses from diffuse subtype occurred within 3 years in contrast to some late relapses observed for nodular subtype, there was no statistically significant difference in relapse free survival or survival between the subtypes. The extent of irradiation had no effect on relapse free survival or survival. We could not find any evidence that LPHD should be treated any different from the classical Hodgkin's disease at this point despite suggestions that it be classified as a non-Hodgkin's B-cell lymphoma.

Stage I Hodgkin disease: radiation therapy and chemotherapy at the University of Texas M. D. Anderson Cancer Center, 1996-1997.

PURPOSE: To summarize 30 years of experience in treatment of and prognosis for stage I Hodgkin disease. MATERIALS AND METHODS: The authors reviewed retrospectively the cases of 196 patients seen and followed up at one institution from 1967 to 1997. All patients were treated with radiation therapy, and 46 also received combination chemotherapy as part of their initial treatment. Radiation therapy techniques included involved or regional-field irradiation in 83 patients, extended field irradiation (mantle or inverted Y) in 74, and subtotal nodal irradiation in 39 (median radiation doses for subclinical and clinical disease were 30 and 40 Gy, respectively, at 1.5-2.0 Gy per fraction). Of 46 patients treated with combination and radiation therapy, 26 received subtotal nodal irradiation; in the remaining 20, chemotherapy was combined with more limited-field radiation therapy. Follow-up ranged from 3 to 356 months (median, 144 months). RESULTS: The actuarial overall survival, disease-specific survival, and freedom from progression at 10 and 20 years were 82% and 66%, 94% and 91%, and 77% and 70%, respectively. In multivariate analysis, age adversely influenced overall survival, and female sex favorably affected freedom from progression. Mixed cellularity histology and mantle field technique adversely influenced disease-specific survival. Laparotomy significantly influenced disease-specific survival but not overall survival. CONCLUSION: Radiation therapy results in an excellent outcome in patients with favorable stage I Hodgkin disease. Pathologic staging is no longer necessary.

Subdiaphragmatic stage I & II Hodgkin's disease: long-term follow-up and prognostic factors.

PURPOSE: To report long-term follow-up results and to analyze prognostic factors for overall and disease-free survival in patients with subdiaphragmatic Stage I & II Hodgkin's disease. METHODS AND MATERIALS: From September 1962 to April 1995, 109 patients presented at the M. D. Anderson Cancer Center with subdiaphragmatic Hodgkin's disease. The medical records of these patients were retrospectively reviewed; 22 patients who received no treatment at the M. D. Anderson Cancer Center or who had radiation therapy at other institutions were excluded. The remaining 87 patients formed the basis of this study. The median age of our group was 33 years with a male: female ratio of 3.3:1. The histological subtypes were nodular sclerosis in 21 (24.1%) patients, mixed cellularity in 31 (35.6%), lymphocyte predominance in 33 (37.9%), lymphocyte depletion in 1 (1.1%) and unclassified histology in 1 (1.1%). Of the patients, 32 (36.8%) underwent laparotomy for diagnosis or staging purpose, 74 (85.1%) had lymphangiography, and 35 (40.2%) had computerized tomography of the abdomen and pelvis. Among the patients, 22 (25%) had more than three sites of nodal involvement at presentation, 56 (64.4%) had pelvic or abdominal disease, and 14 (18.4%) had bulky disease that was defined as disease with the largest dimension > or = 7 cm. Stage distribution was IA in 33.3%, IIA in 39.1%, and IIB in 27.6%. Treatment was radiotherapy alone in 60 (69%) patients, chemotherapy and radiation in 23 (26.4%), and chemotherapy alone in 4 (4.6%). RESULTS: The 10- and 20-year actuarial overall survival rates for all patients were 74.6% and 55.3%, and the corresponding disease-free survival rates were 72.4% and 67.5%, respectively. On univariate analysis, age > 40 years, B symptoms, nodular sclerosis or mixed cellularity histology, and decreased albumin or hemoglobin levels were statistically significant adverse pretreatment factors for overall survival. B symptoms, decreased albumin level, more than 3 sites of disease at presentation, and Stage II were statistically significant negative pretreatment prognostic factors for disease-free survival. Only B symptoms and decreased albumin level predicted worse outcome in both overall and disease-free survivals. On multivariate analysis, age > 40 years, nodular sclerosis and mixed cellularity histology, and decreased hemoglobin levels were three independent risk factors for overall survival. An analysis of the pattern of failure revealed that the majority of the patients with central Stage II disease who did not receive mantle radiation failed in the supradiaphragmatic area. Late complications of radiation were infrequent. CONCLUSIONS: Long-term follow-up of this group of patients revealed similar overall and disease-free long-term survival, as would be expected from supradiaphragmatic Hodgkin's disease. For patients with central Stage II disease, it is anticipated that supradiaphragmatic radiation therapy would improve the disease-free survival.

Hodgkin's disease: correlation of clinical characteristics with probabilities for negative lymphangiogram vs. negative laparotomy findings in patients with Stage I supradiaphragmatic presentations vs. those in patients with Stage II.

PURPOSE: At a time both when late complications and second malignancies have become a growing concern and when staging laparotomy has been largely abandoned and comparative studies for staging Hodgkin's disease by state of the art computed tomography (CT) vs. lymphangiography have revealed minimal differences in results for these procedures, our purpose for undertaking this study was twofold. Our initial reason was to determine and compare probabilities for negative abdominal findings for patients with Stage I presentations with those for patients with Stage II as determined by lymphangiography and subsequently by laparotomy for those patients who had negative lymphangiograms. Our second reason, being an extension of the first, was to create a resource that can be used in conjunction with other information for arriving at appropriate treatment decisions including giving either more or particularly less than standard institutional therapy and especially with respect to the abdomen. METHODS AND MATERIALS: Data on 714 patients with prelymphangiogram Stage I-II upper torso presentations of Hodgkin's disease were entered prospectively in our database between 1968 and 1987. Twenty-eight with lymphocyte predominant disease, who had both negative lymphangiogram and negative laparotomy findings and 17 with questionable diagnoses of lymphocyte-depleted or unclassified disease were excluded from subsequent analyses of 669 patients with nodular sclerosis (NS) and mixed cellularity (MC) diagnoses. RESULTS: Stage I: in final logistic models, negative lymphangiogram findings were associated strongly with a combination of no constitutional symptoms and nodular sclerosis histology, whereas negative laparotomy findings correlated strongly with a combination of no constitutional symptoms and female sex. Predicted probabilities depended on the ratios of favorable to unfavorable characteristics. Stage II: in final logistic models, negative lymphangiogram findings were associated strongly with a combination of no constitutional symptoms, nodular sclerosis histology, age <40 years, and <4 involved sites, whereas negative laparotomy findings correlated strongly with a combination of <4 involved sites and mediastinal disease. Predicted probabilities again depended on the ratios of favorable to unfavorable characteristics. CONCLUSION: This study demonstrated that probabilities for negative abdominal findings for patients with supradiaphragmatic presentations of NS and MC Hodgkin's disease depended on: 1) whether the disease presented as Stage I or as Stage II; 2) whether staging was limited to a lymphangiogram or whether it included a laparotomy; and 3) or whether the clinical features associated with the presenting stage and methods of staging were favorable or unfavorable.

Rapid recovery of spermatogenesis after mitoxantrone, vincristine, vinblastine, and prednisone chemotherapy for Hodgkin's disease.

PURPOSE: Because the effects of mitoxantrone on human male fertility were unknown, we determined prospectively the effects of three courses of mitoxantrone (Novantrone), vincristine (Oncovin), vinblastine, prednisone (NOVP) chemotherapy on the potential for fertility of men with Hodgkin's disease (HD). PATIENTS AND METHODS: Semen analyses were performed on 58 patients with stages I-III HD before, during, and after chemotherapy and after the sperm count recovered from the effects of abdominal radiotherapy that was given after chemotherapy. RESULTS: Before the initiation of treatment, 84% of the patients were normospermic. Sperm counts declined significantly within 1 month after the start of NOVP chemotherapy. In the month after chemotherapy, 38% of patients were azoospermic, 52% had counts < 1 million/ mL, and 10% had counts between 1 and 3 million/mL. Between 2.6 and 4.5 months after the completion of chemotherapy, sperm counts recovered rapidly to normospermic levels in 63% of patients. In the remaining patients who were followed up for at least 1 year after standard upper abdominal radiotherapy, counts also recovered to normospermic levels. CONCLUSION: NOVP chemotherapy, like most other regimens, produced marked temporary effects or spermatogenesis. However, sperm production recovered very rapidly, within 3 to 4 months after the end of NOVP chemotherapy. This pattern was caused by killing differentiating spermatogenic cells, but there was little cytotoxicity or inhibition of stem cells from mitoxantrone or the other drugs. After the combination of NOVP plus abdominal radiotherapy, sperm counts and motility were restored in most patients to pretreatment levels, which were compatible with normal fertility.

Primary non-Hodgkin lymphoma of the large bowel.

PURPOSE: To characterize the natural history of primary non-Hodgkin lymphoma of the large bowel and identify prognostic factors. MATERIALS AND METHODS: Twenty-three patients with primary non-Hodgkin lymphoma according to strict criteria were identified. Seventeen patients underwent resection, and six patients underwent biopsy. Among 19 patients with intermediate- or high-grade lymphoma, 13 had diffuse large cell lymphoma. Ann Arbor stage was I in 15 cases, II in seven cases, and IV in one case. In 15 patients, the International Prognostic Index was available: 0, eight patients; 1, six patients; and 3, one patient. Postoperatively, six patients received combined chemotherapy and radiation therapy, eight patients received chemotherapy, and six patients received radiation therapy. Overall and relapse-free survival were calculated actuarially, and univariate analysis was performed with regard to stage, treatment, extent of surgery, and the International Prognostic Index. RESULTS: Median follow-up was 144 months. Two patients' disease recurred. Overall and relapse-free survival at 10 years were 61% and 82%, respectively. The International Prognostic Index was the only significant prognostic factor for overall survival (P = .03, log-rank test). CONCLUSION: The prognosis of primary non-Hodgkin lymphoma appears to be as good as that of low- or intermediate-grade lymphoma. The only significant prognostic factor for overall survival is the International Prognostic Index.

Long-term outcome of treatment for Ann Arbor stage 1 Hodgkin's disease: patterns of failure, late toxicity and second malignancies.

PURPOSE: Radiation therapy results in excellent short-term survival in patients with early-stage Hodgkin's disease. However, the optimal therapeutic scheme that achieves the highest disease-free survival with the minimum long-term toxicity is yet to be determined. An analysis of the patterns of failure and late complications after radiation therapy was conducted to address this question. METHODS AND MATERIALS: A retrospective study was conducted of 145 patients with Stage I Hodgkin's disease treated at M. D. Anderson Cancer Center from 1967 through 1987. Follow-up extended from a minimum of 30 to 339 months, with a median period of observation of 16.5 years. All the patients were treated with radiation therapy and, and 16 received combination MOPP-based chemotherapy as part of their initial treatment. The radiotherapy technique, was involved/regional in 71 (49%), extended in 62 (43%), and subtotal nodal irradiation in 12 patients. The median total dose was 40 Gy. RESULTS: The actuarial freedom from progression at 10 and 20 years was 76% and 69%, respectively. Forty of 145 patients relapsed (27.6%). The site of primary disease was cervical adenopathy in 30 (75%), axillary in 7 (17.5%), mediastinal in 2 patients and subdiaphragmatic in one patient. Twenty-two patients were treated with involved/regional technique (55%), 17 with extended (42.5%), and 1 with subtotal nodal irradiation technique. There were three in field and four marginal recurrences. Six relapses occurred in non-irradiated nodal regions at the same side of the diaphragm and 17 in non-irradiated transdiaphragmatic lymph nodes (57.5%). Nine patients (22.5%) relapsed with visceral disease. Nineteen patients (47.5%) relapsed within the first 2 years, 15 (37.5%) 3 to 10 years after diagnosis and the remaining 6 (15%) after 10 years. Eleven of 40 patients died of disease after the first or subsequent relapses (27.5%). Three of six patients with late relapses had progression in viscera but only two died with disease. Thirty-eight of 145 patients developed late toxicity from the treatment (26.2%). Twenty-three patients experienced ischemic heart disease (15.9%), only 13 of whom received mediastinal irradiation (9%). Fifteen patients developed secondary malignant solid tumors (10.3%). Nine of those (6.2%) occurred within the irradiation field (two were also treated with chemotherapy). Two additional patients, one of whom received chemotherapy as part of the initial treatment, died of acute myelogenous leukemia. Non-Hodgkin's lymphoma and lung cancer were the most common second malignancies. CONCLUSIONS: Limited field radiotherapy results in a significant number of relapses in non-irradiated, especially transdiaphragmatic lymph nodes. Subtotal nodal irradiation can prevent some relapses and therefore improve freedom from progression. Careful design of the treatment fields may decrease the risk of morbidity and mortality from coronary artery disease and second malignancies in early-stage Hodgkin's disease. Careful long-term surveillance may permit early detection and management of late relapses and treatment complications.

Long-term outcome of treatment for Ann Arbor Stage I Hodgkin's disease: prognostic factors for survival and freedom from progression.

PURPOSE: The earliest stages of Hodgkin's disease are associated with excellent short-term survival with radiation therapy. This has led to controversies regarding pretreatment evaluation, the extent of irradiation, the role of chemotherapy, and the relative importance of prognostic factors. Long-term results were sought to address these controversies. METHODS AND MATERIALS: A retrospective study was conducted of patients with Stage I Hodgkin's disease treated at the M. D. Anderson Cancer Center from 1967 through 1987. The median age at presentation of 145 patients was 31 years, and the male-to-female ratio was 1.8. Pretreatment evaluation included lymphangiography and bone marrow aspiration and biopsy in all patients. Laparotomy was performed in 101 of the 145 patients (70%). There were 133 patients with supradiaphragmatic presentations; 12 patients had infradiaphragmatic adenopathy. Only five patients had B symptoms (3.5%). Histologic subtypes of the disease included lymphocyte predominance 17.9%, nodular sclerosis 40.7%, mixed cellularity 40.7%, and one unclassified Hodgkin's disease with primary splenic involvement. All patients were treated with radiotherapy, and 16 (11%) also received combination chemotherapy as part of their initial treatment. Radiotherapy techniques included involved/regional field in 49%, extended field in 42.7% (mantle or inverted Y), and subtotal nodal irradiation in 8.3%. Follow-up extended from a minimum of 30-339 months, with a median period of observation of 16.5 years. RESULTS: The median survival was 13.7 years. The 10- and 20-year survival rates were 83% and 66%, respectively. The only factor important for decreased survival was age >40 years at diagnosis (p < 0.0001). Out of 43 deaths, 11 were the result of Hodgkin's disease and the remaining 32 resulted from intercurrent disease, including treatment-related causes. Median freedom from progression was 10.5 years, and the 10- and 20-year freedom from progression were 76% and 69%, respectively. Out of 39 relapses, 5 (13%) occurred beyond 10 years. Women had higher freedom from progression (p = 0.0534) than men. Age, histology, bulk of disease, site of involvement including the mediastinal presentations, and the addition of chemotherapy did not influence the freedom of progression. Although very few patients (12 of 145) received subtotal nodal irradiation, the freedom from progression at 10 years was 91.7% for this group versus 64.7% for the group of patients who were treated with more limited techniques. CONCLUSION: Treatment with radiation therapy for patients with Stage I Hodgkin's disease leads to an excellent outcome, but patients require long-term surveillance as late relapses are not rare. Age is the only factor that affects survival, and gender marginally affects freedom from progression. Subtotal nodal irradiation may improve freedom from progression; further investigation of this treatment is justified.

High rate of prolonged remissions following combined modality therapy for patients with localized low-grade lymphoma.

PURPOSE: Involved field (IF) radiation can cure as many as 40% to 50% of patients with stage I-II low-grade lymphoma. We sought to improve these results by prospectively evaluating the combination of IF radiation and chemotherapy consisting of 10 courses of cyclophosphamide, vincristine, prednisone, and bleomycin, with doxorubicin added in a risk-adapted manner (COP/CHOP-Bleo). PATIENTS AND METHODS: From 1984 until December 1992, 91 patients, median age 56 years (range 28 to 77 years), with clinical stage I-II low-grade lymphoma were treated. No patients were excluded on the basis of age or organ function. RESULTS: A complete response was attained in 99% of evaluable patients. Treatment-related toxicity was mild, and no deaths occurred during therapy. With a median follow-up of 60 months, there have been only 16 relapses. The actuarial freedom from relapse rate at five years is 82% (95% confidence interval 71% to 89%) and at 10 years is 73%. At five years the overall survival rate is 90% (95% confidence interval 81% to 95%) and at ten years it is 82%. Of the clinical features examined, only older age (> 56 years; p = 0.07) was associated with shorter survival. No features examined were predictive of disease relapse. CONCLUSION: The combination of IF radiation and risk-adapted COP/CHOP-Bleo chemotherapy is well-tolerated, produces a very high rate of complete remission, and with a median follow-up of five years, has produced lower rates of relapse and better overall survival than has been reported for IF radiation alone in patients with clinically-staged I-II low-grade lymphoma.

Long term assessment of patterns of treatment failure and survival in patients with stage I or II follicular lymphoma.

BACKGROUND: Follicular lymphoma is a clearly defined type of malignant lymphoma. The many treatment approaches reported in the literature attest to the lack of agreement on its best management. The treatment experiences of patients with Stage I or II follicular lymphoma who were at risk for at least 5 years were reviewed to assess their survival, disease free survival, and patterns of failure. METHODS: Between 1974 and 1988, 144 patients with Stage I or II follicular lymphoma were treated at The University of Texas M. D. Anderson Cancer Center. Initial staging studies included lymphangiography in 87% of the patients, computerized tomography of the abdomen and pelvis in 60%, bone marrow biopsy in 98%, and diagnostic or staging laparotomy in 33%. Forty-five patients were treated with regional radiotherapy, 84 patients with combined chemotherapy and radiotherapy, and 15 patients were treated with chemotherapy alone. RESULTS: With a median follow-up of 8.7 years (range, 48-182 months) the actuarial survival rates at 5, 10, and 15 years were 81, 69, and 63%, respectively. The freedom from relapse (FFR) rates were 66, 56, and 46%, respectively. The FFR rate was better for patients treated with chemotherapy-radiotherapy than for patients treated with radiotherapy alone (63 vs. 35% at 15 years). In addition, there were no relapses after 7.5 years in patients treated with chemotherapy-radiotherapy, but relapses continued even beyond 15 years in patients treated with radiotherapy alone. Univariate analysis for each of the treatment groups revealed age to be the only significant prognostic factor. There was no significant difference in survival or disease free survival rates for the three histologic subtypes of follicular lymphoma. CONCLUSION: The addition of chemotherapy to radiotherapy may have increased the probability of cure for patients with Stages I or II follicular lymphoma.

Treatment of patients with lymphomas of the uterus or cervix with combination chemotherapy and radiation therapy.

BACKGROUND: Primary lymphomas of the uterus or cervix are so rare that treatment series of single institutions consist of very small numbers of patients, making standard treatment difficult to define. The outcome of patients treated with a combination of chemotherapy and radiation therapy was analyzed for all but patients with the most advanced disease. METHODS: From 1976 to 1992, 16 patients received definitive treatment. Thirteen patients had intact uteri (group 1) and 3 presented with paracolpal lymphomas after previous hysterectomies (group 2). Twelve of the patients received chemotherapy and external irradiation. The remaining four underwent only chemotherapy. The overall survival and freedom from disease progression were analyzed according to Kaplan-Meier methods. Prognoses were related to the International Index, Ann Arbor stage, and International Federation of Gynecology and Obstetrics stage. RESULTS: Five-year survival and freedom from disease progression were 77% and 67%, respectively, for group 1, and all patients in group 2 were cured. A statistically significant correlation of survival with scores of the International Index was found in group 1. For patients with scores in the low or low-intermediate range (n = 10), 5-year survival was 90%. All patients who scored in the high-intermediate or high range (n = 3) died by 66 months after their diagnosis (P = 0.0153). The Ann Arbor stage had less predictive value, with 5-year survival of 89% for Stage I and II patients (n = 9), compared with 50% survival for the four Stage III and IV patients (P = 0.0701). International Federation of Gynecology and Obstetrics staging did not predict outcome. CONCLUSIONS: The combination of chemotherapy and irradiation is the most effective treatment regimen for all uterine and cervical lymphomas. The International Index is most predictive of outcome.

Incidence of second cancers in patients treated for Hodgkin's disease.

BACKGROUND: Numerous studies of treatment for Hodgkin's disease have demonstrated large increases in the incidence of leukemia in the early years following chemotherapy, although the duration of effect and the specific agents involved are not well understood. Also, some, but not all, studies have indicated that the incidence of certain solid tumors increases following treatment for Hodgkin's disease. PURPOSE: We studied the association between treatment for Hodgkin's disease and the incidence of second cancers. METHODS: We conducted a study within a cohort that included 10,472 patients from 14 cancer centers in the United States and Canada who were first diagnosed as having Hodgkin's disease at some point from 1940 through 1987. Discounting the 1st year after diagnosis, the average length of follow-up was 7.1 years per subject. RESULTS: We observed 122 leukemias and 438 solid tumors. The relative risk (RR) of leukemia following chemotherapy, compared with no chemotherapy, was 14 (95% confidence interval [CI] = 5.6-35). Increased risks of leukemia were observed after treatment with chlorambucil (RR = 2.0; 95% CI = 1.1-3.6), procarbazine (RR = 4.9; 95% CI = 2.6-9.1), vinblastine (RR = 1.7; 95% CI = 1.1-2.8), and a group of rarely used drugs that included methotrexate, vindesine, etoposide, and 22 others (RR = 3.8; 95% CI = 1.9-7.4). RRs were also estimated for various combinations of drugs, including MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) (RR = 5.9; 95% CI = 2.9-12) and ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) (RR = 1.5; 95% CI = 0.7-3.4). The RR of leukemia associated with splenectomy was 1.6 (95% CI = 1.0-2.5). The RR of solid tumors following chemotherapy was 1.4 (95% CI = 1.1-1.8). For the group of rarely used drugs, the RR of solid tumors was 3.1 (95% CI = 1.7-5.8). Chemotherapy was associated with an increased risk of cancers of the bones, joints, articular cartilage, and soft tissues (RR = 6.0; 95% CI = 1.7-20), and cancers of the female genital system (RR = 1.8; 95% CI = 1.1-3.2). In patients followed for 10 or more years after radiotherapy, increased risks were found for cancers of the respiratory system and intrathoracic organs (RR = 2.7; 95% CI = 1.1-6.8) and for cancers of the female genital system (RR = 2.4; 95% CI = 1.1-5.4). CONCLUSIONS: Procarbazine, chlorambucil, and vinblastine are associated with increased leukemia risk. Combination drug regimens have leukemogenic effects estimated as the product of RRs for individual drugs. Chemotherapy and radiotherapy increase the risk of selected solid tumors, and the effect of chemotherapy on solid tumor risk is weaker than the leukemogenic effect. IMPLICATIONS: Without doubt, the benefits of treatment of Hodgkin's disease outweigh the risk of a subsequent malignancy, but data on the carcinogenic effects of radiation and drugs beyond 10 years after treatment continue to be sparse, and future analyses should be directed at long-term survivors.

Significance of tumor size and radiation dose to local control in stage I-III diffuse large cell lymphoma treated with CHOP-Bleo and radiation.

PURPOSE: The purpose of this study was to evaluate the possible effect of adjunctive involved field (IF) radiotherapy on long-term local control for patients with Ann Arbor Stage I-III diffuse large cell lymphoma (DLCL) who achieved a complete remission on a combined modality program which included cyclophosphamide, doxorubicin, vincristine, prednisone, and Bleomycin (CHOP-Bleo). METHODS AND MATERIALS: One hundred and ninety patients with Ann Arbor Stage I-III DLCL were treated with CHOP-Bleo and radiotherapy. Analyses were undertaken to determine (a) response to treatment according to stage, extent of maximum local disease, and irradiation dose either < 40 Gy or > or = 40 Gy and (b) relapse patterns. RESULTS: A complete remission (CR) was achieved in 162 patients. Among patients who achieved a CR, local control was better for those who received tumor doses of > or = 40 Gy (97%) than for those who received < 40 Gy (83%) (p = 0.002.) Among those with extensive local disease, the corresponding control rates were 88% and 71%, respectively. A study of distant relapse patterns following a CR showed that the first relapse usually involved an extranodal site. CONCLUSION: Radiotherapy was an effective adjunctive treatment to CHOP-Bleo for patients with stage I-III DLCL who achieved a CR. Patterns of relapse suggested that total nodal irradiation (TNI) possibly could have benefited a small subset of patients.
