Natural killer/natural killer-like T-cell lymphoma, CD56+, presenting in the skin: an increasingly recognized entity with an aggressive course.

PURPOSE: To describe and identify the clinical and pathologic features of prognostic significance for natural killer (NK) and NK-like T-cell (NK/T-cell) lymphoma presenting in the skin. PATIENTS AND METHODS: This study was a retrospective review of 30 patients with CD56+ lymphomas initially presenting with cutaneous lesions, with analysis of clinical and histopathologic parameters. RESULTS: The median survival for all patients was 15 months. Those with extracutaneous manifestations at presentation (11 patients) had a shorter median survival of 7.6 months as compared with those without extracutaneous involvement (17 patients), who had a more favorable median survival of 44.9 months (P =.0001). Age, gender, extent of cutaneous involvement, and initial response to therapy had no statistically significant effect on survival. Seven patients (24%) had detectable Epstein-Barr virus (EBV) within neoplastic cells. The patients with tumor cells that coexpress CD30 (seven patients) have not yet reached a median survival after 35 months of follow-up as compared with those with CD30- tumor cells (20 patients), who had a median survival of 9.6 months (P <.02). Routine histopathologic characteristics had no prognostic significance nor did the presence of CD3epsilon, EBV, or multidrug resistance. CONCLUSION: NK/T-cell lymphoma is an aggressive neoplasm; however, a subset with a more favorable outcome is identified in this study. The presence of extracutaneous disease at presentation is the most important clinical variable and portends a poor prognosis. The extent of initial skin involvement does not reliably predict outcome. Patients from the United States with NK/T-cell lymphoma presenting in the skin have a low incidence of demonstrable EBV in their tumor cells. Patients with coexpression of CD30 in CD56 lymphomas tend to have a more favorable outcome.

Clinical characteristics and outcome of patients with extracutaneous mycosis fungoides.

PURPOSE: To identify prognostic factors predictive of outcome in patients with extracutaneous (stage IV) mycosis fungoides (MF) and to evaluate the risk of progression to extracutaneous disease by initial extent of skin involvement. PATIENTS AND METHODS: One hundred twelve patients with extracutaneous disease at presentation or with progression and 434 patients with initial cutaneous-only disease were identified. Actuarial survival curves were plotted according to the Kaplan-Meier technique. RESULTS: The median survival of all stage IV patients was 13 months from the date of first treatment for stage IV disease. Sex, race, age, extent of skin involvement, and peripheral blood Sezary cell involvement were not significant to survival outcome. Eleven patients (10%) had a complete response to therapy resulting in a significantly improved median survival compared with patients with a partial or no response (1.70 v 0.91 years, P =.047 and 1.70 v 0.57 years, P =.011, respectively). At 20 years from diagnosis, the risk for progression to extracutaneous disease by initial extent of skin involvement was 0% for limited patch/plaque, 10% for generalized patch/plaque, 35.5% for tumorous disease, and 41% for erythrodermic involvement. CONCLUSION: This was a larger scale study over a longer time period than had been completed previously on extracutaneous MF. Prognostic factors important in the cutaneous stages of disease are no longer significant once extracutaneous disease develops. Patients who had a more favorable response to therapy may have had a biologically less aggressive disease than their less fortunate counterparts. The risk of developing stage IV MF is highest in patients presenting with tumorous or erythrodermic skin disease and is lowest in patients with limited skin involvement.

High-dose therapy and autologous bone marrow transplantation for follicular lymphoma in first complete or partial remission: results of a phase II clinical trial.

Advanced stage follicular small cleaved and mixed cell lymphoma is characterized by relapse from remission and survival ranging from 6 to 12 years. Because young patients have the greatest compromise in longevity, the efficacy and toxicity of high-dose radiochemotherapy and bone marrow transplantation after conventional chemotherapy was evaluated in a prospective phase II clinical trial. Thirty-seven patients in a minimal disease state after conventional chemotherapy received fractionated total body irradiation and high-dose etoposide and cyclophosphamide, followed by purged autologous bone marrow. A reference sample of 188 patients of similar age, stage, and histology managed at this institution before 1988 was identified for comparison of patient characteristics and outcomes. Compared with reference patients, transplant recipients had a higher tumor burden at diagnosis. With a median follow-up of 6.5 years, the estimated 10-year survival after transplantation was 86%. There was a single lymphoma death yielding a 10-year disease-specific survival of 97%. There were 2 early transplant-related deaths and 2 late acute leukemia deaths. Ten patients relapsed, one with microscopic disease only. High tumor burden at diagnosis and incomplete response to chemotherapy adversely influenced survival in the reference but not in the transplanted patients. The estimated risk of death of 14% and relapse of 30% at 10 years in our transplanted follicular lymphoma patients, the majority of whom had high tumor burdens, compares favorably with our observations in appropriately matched reference patients.

High-dose therapy and autologous hematopoietic-cell transplantation for follicular lymphoma beyond first remission: the Stanford University experience.

A retrospective analysis was performed to investigate the outcome of high-dose therapy (HDT) and autologous hematopoietic cell transplantation in patients with follicular lymphomas beyond first remission. Ninety-two patients with primary induction failure or relapsed follicular low-grade lymphoma (FLGL), follicular large cell lymphoma (FLCL), and transformed follicular lymphoma (TFL) were treated with myeloablative therapy consisting of etoposide (60 mg/kg), cyclophosphamide (100 mg/kg), and either carmustine (BCNU;15 mg/kg) or fractionated total body irradiation (FTBI; 1200 cGy) followed by transplantation of purged autologous bone marrow or peripheral blood hematopoietic cells. For the 49 patients with relapsed FLGL, the median age was 49 years and the median interval from diagnosis to HDT was 30 months. The 4-year estimate of overall survival (OS) was 60% (95% confidence interval [CI], 45%-75%) and of disease-free survival (DFS) was 44% (95% CI, 29%-59%). Treatment with the FTBI-containing HDT regimen was associated with significantly longer DFS (P = .04) and OS (P = .04) in our multivariate analysis. OS was also significantly longer among those treated with 3 or fewer chemotherapy regimens. For the 26 FLCL patients, the median age was 51 years and in 31% the indication for HDT was primary induction failure. For FLCL patients, the 4-year estimate of OS was 58% (95% CI, 37%-79%) and of DFS was 51% (95% CI, 30%-72%). Among the 17 patients with TFL, 13 (76%) transformed at first relapse, and only 6 patients (35%) achieved complete remission with salvage therapy prior to HDT. For TFL patients, the 4-year estimate of OS was 50% (95% CI, 24%-76%) and of DFS 49% (95% CI, 20%-78%). There were 3 occurrences of myelodysplasia (1 after treatment with TBI, 2 after BCNU treatment), yielding an estimated incidence of 7% (95% CI, 0%-16%) at 56 months. This analysis shows that relapsed FLGL patients treated with 3 or fewer different chemotherapy regimens show inferior survival. The HDT regimen containing FTBI appears to be superior to the BCNU-based regimen for relapsed FLGL, although longer follow-up is needed to evaluate late effects. Lastly, patients with TFL or induction failure and relapsed FLCL can achieve survival outcome comparable to those observed with the indolent follicular lymphomas.

Toxicity of high-dose sequential chemotherapy and purged autologous hematopoietic cell transplantation precludes its use in refractory/recurrent non-Hodgkin's lymphoma.

We conducted a pilot study in 20 patients with high-risk or recurrent/refractory non-Hodgkin's lymphoma (NHL) using high-dose sequential chemotherapy (HDSC) and autologous hematopoietic cell transplantation (AHCT). After cytoreduction with standard salvage therapy, HDSC/AHCT was administered in 4 phases at 2- to 4-week intervals. Phase 1 consisted of cyclophosphamide 7 g/m2 followed by granulocyte colony-stimulating factor (G-CSF) at 10 microg/kg per day and leukapheresis upon recovery from white blood cell nadir. The hematopoietic cell product was enriched by Percoll gradient separation and purged with a B-cell or T-cell monoclonal antibody panel and complement. Phase 2 consisted of methotrexate 8 g/m2 with leucovorin rescue and vincristine 1.4 mg/m2. Phase 3 was etoposide 2 g/m2 with G-CSF 5 microg/kg per day. In phase 4, the preparative regimen of mitoxantrone 60 mg/m2 and melphalan 180 mg/m2 was administered followed by AHCT. The NHL histologies were diffuse large cell, follicular/diffuse mixed, small noncleaved cell, T-cell-rich B-cell, lymphoblastic, and peripheral T cell. The remission status was first partial remission (PR1; n = 1) or beyond first complete remission (post-CR1; n = 19). Of the 20 patients enrolled, 11 proceeded through all 4 phases. Nine were removed from the study after the first or second phase because of progressive disease (n = 5), poor hematopoietic cell mobilization (n = 1), excessive toxicity (n = 2), and chronic active hepatitis C (n = 1). Treatment-related toxicities in the remaining 11 transplant recipients were cardiomyopathy, hemorrhagic cystitis, persistent cytopenias, acute renal failure, abnormal liver function test results, and infectious complications. There were no treatment-related deaths. Eight of the 11 transplant recipients were alive, 6 without disease, at a median follow-up of 2.7 years. The estimated median 2-year event-free survival was 55%, and overall survival was 70%. We conclude that HDSC/AHCT in refractory/recurrent NHL is associated with considerable acute and chronic toxicities. Given the toxicity profile, efficacy data were not sufficiently promising to warrant further study.

Management of breast cancer after Hodgkin's disease.

PURPOSE: To evaluate the incidence, detection, pathology, management, and prognosis of breast cancer occurring after Hodgkin's disease. PATIENTS AND METHODS: Seventy-one cases of breast cancer in 65 survivors of Hodgkin's disease were analyzed. RESULTS: The median age at diagnosis was 24.6 years for Hodgkin's disease and 42.6 years for breast cancer. The relative risk for invasive breast cancer after Hodgkin's disease was 4.7 (95% confidence interval, 3.4 to 6. 0) compared with an age-matched cohort. Cancers were detected by self-examination (63%), mammography (30%), and physician exam (7%). The histologic distribution paralleled that reported in the general population (85% ductal histology) as did other features (27% positive axillary lymph nodes, 63% positive estrogen receptors, and 25% family history). Although 87% of tumors were less than 4 cm, 95% were managed with mastectomy because of prior radiation. Two women underwent lumpectomy with breast irradiation. One of these patients developed tissue necrosis in the region of overlap with the prior mantle field. The incidence of bilateral breast cancer was 10%. Adjuvant systemic therapy was well tolerated; doxorubicin was used infrequently. Ten-year disease-specific survival was as follows: in-situ disease, 100%; stage I, 88%; stage II, 55%; stage III, 60%; and stage IV, zero. CONCLUSION: The risk of breast cancer is increased after Hodgkin's disease. Screening has been successful in detecting early-stage cancers. Pathologic features and prognosis are similar to that reported in the general population. Repeat irradiation of the breast can lead to tissue necrosis, and thus, mastectomy remains the standard of care in most cases.

Assessment of the stanford V regimen and consolidative radiotherapy for bulky and advanced Hodgkin's disease: Eastern Cooperative Oncology Group pilot study E1492.

PURPOSE: This study was performed, in a multi-institutional setting, to evaluate the efficacy and feasibility of the Stanford V chemotherapy regimen plus radiotherapy to bulky Hodgkin's disease sites. PATIENTS AND METHODS: A two-stage design was implemented in a phase II study involving 47 patients with bulky mediastinal stage I/II or stage III/IV Hodgkin's disease. Twelve weeks of the Stanford V chemotherapy regimen were given with consolidative radiotherapy (36 Gy) to lymph nodes >/= 5 cm and/or macroscopic splenic disease. Treatment was administered in one of five institutions participating in the Eastern Cooperative Oncology Group. RESULTS: With a median follow-up of 4.8 years, 45 patients are alive and 40 have been continuously disease-free. The estimated freedom from progression was 87% at 2 years and 85% at 5 years. Overall survival was 96% at 2 and 5 years. There was one death from Hodgkin's disease and one death from an M5 acute leukemia. Six of seven relapsed patients received high-dose therapy and autologous stem-cell transplantation. The freedom from second progression for the seven relapsed patients was estimated at 98% at 3 years. CONCLUSION: Stanford V chemotherapy and consolidative radiotherapy to bulky disease is effective in bulky and advanced Hodgkin's disease in a multi-institutional setting. On this basis, an Intergroup study comparing doxorubicin, bleomycin, vinblastine, and dacarbazine with the Stanford V regimen has been initiated.

What is the significance of nasal involvement in nasopharyngeal carcinoma?

PURPOSE: The purpose of this study was to differentiate the patterns of nasal fossa involvement in nasopharyngeal carcinoma (NPC) and to clarify its prognostic influence on local control and survival after radiation therapy. METHODS AND MATERIALS: Between November 1989 and July 1991, 218 patients with histologically proven local-regional NPC were treated with radiotherapy following the protocol at the Department of Radiation Oncology, Cancer Hospital, Shantou University School of Medicine. All patients had pretreatment CT scans. Fiberoptic endoscopic examination was performed every week during treatment and at the time of every follow-up visit to define the initial extent of disease and to evaluate treatment response. No chemotherapy or brachytherapy was given. RESULTS: Of the 218 patients, 87 had nasal involvement. Sixty of them had a pattern of mucosal infiltration (MI), another 27 had an exophytic protruding (EP) component. The likelihood of residual disease after irradiation, the local relapse rate, 5-year freedom from progression rate (FFP), and death rate associated with local relapse (DRALR) of MI and EP were 36.7% vs. 3.7%, 30.0% vs. 7.4%, 26.7% vs. 51.8%, and 25.0% vs. 3.7% with p<0.004, p<0.005, p<0.02, and p<0.03, respectively. Multivariate analysis in this selected group demonstrated that infiltration of nasal fossa mucosa was an independent prognostic factor on primary control and freedom from progression. CONCLUSION: Differentiation of nasal fossa involvement according to MI or EP is of value in predicting the outcome of treatment. We suggest that only the MI group should be considered as nasal involvement in the staging of NPC.

Total skin electron beam therapy with or without adjuvant topical nitrogen mustard or nitrogen mustard alone as initial treatment of T2 and T3 mycosis fungoides.

PURPOSE: To compare the efficacy of total skin electron beam therapy (TSEBT) with or without adjuvant topical nitrogen mustard (+/- HN2) with topical nitrogen mustard (HN2) alone as initial management of T2 and T3 mycosis fungoides (MF). METHODS AND MATERIALS: A retrospective analysis of 148 patients presenting to Stanford from January, 1970 through January, 1995 within 4 months of pathologic diagnosis of MF. Fifty-five patients with T2 and 27 with T3 disease received TSEBT +/- HN2. Fifty-four patients with T2 and 12 with T3 disease received HN2 alone. Boosts with radiotherapy were usually administered to cutaneous tumors of patients with T3 disease. RESULTS: TSEBT +/- HN2 yielded significantly higher complete response (CR) rates than did HN2 alone in patients with T2 and T3 disease (76% vs 39%, p = 0.03 for T2, and 44% vs 8%, p < 0.05 for T3, respectively). In T2 disease, treatment with adjuvant HN2 was associated with a longer freedom from relapse following TSEBT when compared to observation following a CR to TSEBT (p = 0.068). However, no significant differences in survival were observed for different management programs for T2 or T3 disease. In T2 disease, both TSEBT and HN2 were as effective as salvage therapy as when utilized as initial therapy. However, salvage therapy in T3 disease was rarely effective. Limited tumor involvement in T3 disease did not correlate with improved survival compared to more generalized tumorous disease. MF contributed to 27% and 68% of deaths in patients with T2 and T3 disease, respectively. CONCLUSION: Because of high response rates, management of significantly symptomatic or extensive T2 MF should include TSEBT, and adjuvant HN2 should be administered after a CR to TSEBT. Patients with T2 disease who fail TSEBT or HN2 can be salvaged with the other modality. TSEBT is also an effective treatment for T3 disease. The small subset of patients with limited T3 disease may also be treated with HN2 and local radiotherapy to the tumors. Further investigations are necessary to improve the overall outcome for T3 mycosis fungoides.

Results of the 1988-1989 Patterns of Care Study process survey for Hodgkin's disease.

PURPOSE: To document national standards of care for patients receiving radiotherapy as part of curative treatment for Hodgkin's disease. MATERIALS AND METHODS: A national survey was conducted of 61 institutions treating 275 patients with Stages I-III Hodgkin's disease and representing six facility type strata. Pretreatment evaluation, radiotherapy treatment parameters, and use of combined modality therapy were assessed. RESULTS: Ann Arbor stage for the 275 patients was as follows: IA, 69 (25%); IB, 7 (3%); IIA, 123 (45%); IIB, 36 (13%); IIIA 23 (8%), IIIB, 14 (5%); unknown, 3 (1%). Pretreatment evaluation included complete blood count for 93%, sedimentation rate in 29%, chest CT in 88%, abdominal CT scan in 87%, and bone marrow biopsy in 81%. Lymphangiograms were obtained in 50% of cases; laparotomy was performed in 46%. The yield of positive findings in the spleen at laparotomy was 6.5 % overall. Facility differences with respect to staging were seen only for the use of gallium scans, which were more commonly used in academic centers (44% vs. 15-23% elsewhere, p<0.001). Radiotherapy was delivered with a linear accelerator in 94% of cases. Treatment simulation was performed for 94% and individualized blocks constructed for 95% overall; however, freestanding facilities had a lower rate of performance of these procedures (78% vs. 98-99% for simulation and 88% vs. 96-99% for customized blocking, p<0.001). The mean supradiaphragmatic dose was 36.74 Gy and the mean subdiaphragmatic dose was 33.81 Gy. Planned combined modality therapy was given in 36% of patients. The use of combined modality therapy by stage was as follows: IA, 11%; IB, 43%; IIA, 30%; IIB, 68%; IIIA, 57%; IIIB, 100%. Chemotherapy was completed prior to radiation in 80% of cases and generally consisted of ABVD (32%), an alternating regimen (25%), or MOPP (22%). Among Stage I/II patients, use of chemotherapy was associated with reduced radiation doses (mean supradiaphragmatic dose 34.53 Gy vs. 38.43 Gy and mean subdiaphragmatic dose 31.27 Gy vs. 34.51 Gy), and reduced volumes of treatment (87% vs. 28% treated to one side of the diaphragm only). Laparotomy was not associated with decreased supra- or subdiaphragmatic radiation doses or decreased volumes of treatment. CONCLUSIONS: With the exception of gallium scans, pretreatment evaluation is relatively uniform across facility strata. Increased understanding of prognostic factors in Hodgkin's disease and greater use of planned combined modality therapy for higher risk patients appears to have contributed to a decreased use of and low yield of positive findings for laparotomy. Laparotomy was not associated with reduced radiation volumes or doses. Freestanding radiation facilities had a lower rate than other facility types for the performance of treatment simulation and customized patient blocking.

Clinical characteristics and long-term outcome of patients with generalized patch and/or plaque (T2) mycosis fungoides.

OBJECTIVES: To study the long-term results of treatment of patients with generalized patch and/or plaque mycosis fungoides and to identify clinical characteristics predictive of survival and response to treatment. DESIGN: A single-center, 35.5-year retrospective cohort analysis. SETTING: Private referral medical center. PATIENTS: One hundred seventy-six patients with generalized patch and/or plaque (T2) mycosis fungoides. MAIN OUTCOME MEASURES: Long-term actuarial survival and freedom-from-relapse results as calculated by the Kaplan-Meier method. RESULTS: The long-term (35.5-year) survival of patients with T2 mycosis fungoides is worse than the expected survival of a race-, age-, and sex-matched control population (P<.001). The median survival of the T2 group is 11.7 years. Patients younger than 58 years (median age) at presentation have a more favorable overall and disease-specific survival than the patients who are 58 years or older (P<.001 vs P<.025). Patient sex or race had no significant effect on overall survival. Patients who presented with palpable clinically significant lymph nodes (stage IIA) had long-term survival results similar to those without lymphadenopathy (stage IB), despite improved freedom-from-relapse outcome for patients with stage IB. Twenty-four percent of patients who progressed to more advanced disease had a lower complete response rate to initial therapy than did other patients (21% vs 65%) (P<.001). Patients who received total skin electron beam therapy had a better complete response rate than patients treated with topical mechlorethamine hydrochloride alone; the relapse-free results were superior in patients with a total dose of 30 Gy or higher and in patients who received topical mechlorethamine as adjuvant therapy following total skin electron beam therapy. Despite differences in freedom-from-relapse results among different treatment groups, long-term overall or disease-specific survivals were not significantly different. CONCLUSIONS: A significant proportion (24%) of patients with generalized patch and/or plaque (T2) mycosis fungoides experience disease progression to a more advanced clinical stage, and nearly 20% eventually die of the disease. Younger patients have a more favorable disease-specific long-term outcome than patients who are older. Presence of lymphadenopathy (stage IIA) at diagnosis does not predict worse long-term survival outcome. Clinical features predictive of disease progression include initial lymphadenopathy (stage IIA) and lack of complete response to initial treatment. Despite superior complete response rate to a 30-Gy or higher dose of total skin electron beam therapy, topical mechlorethamine proves to be a cost-effective initial treatment for patients with T2 disease. The concept of an adjuvant therapy after irradiation is appealing, although it may not lead to improved long-term survival.

Epidermotropic cutaneous B-cell lymphoma mimicking mycosis fungoides.

Cutaneous involvement by B-cell lymphoma is often secondary to systemic disease. Primary cutaneous B-cell lymphomas are less common, and patients generally have an excellent prognosis. We present a patient with cutaneous B-cell lymphoma with clinical and histologic features mimicking mycosis fungoides. Although the patient was initially misdiagnosed as having a T-cell lymphoma, immunophenotypic studies demonstrated that this was a B-cell lymphoma.

Mycosis fungoides and the Sézary syndrome.

Mycosis fungoides (MF) and the Sézary syndrome are a group of extranodal non-Hodgkin's lymphomas of T-cell origin with primary cutaneous involvement. The group distinguishes itself from other primary cutaneous T-cell lymphomas (CTCLs) by its unique clinical features and histopathology. In its early stages, it often resembles common benign dermatoses, and therefore, a definitive diagnosis can be delayed. The affected T cells are characterized by a predominant CD4+ phenotype with frequent loss of CD7 (pan-T-cell antigen) and often demonstrate T-cell receptor (TCR) rearrangement. The prognosis of patients with MF is highly dependent on the extent and type of skin involvement. The initial cutaneous presentation of MF can be patches, plaques, tumors, or erythroderma. Patients who present with limited patch/plaque disease have an outstanding prognosis with an overall long-term survival that is similar to the expected survival of a matched control population. It is exceedingly rare for patients who present with limited or generalized patch/plaque disease without peripheral lymphadenopathy to have extracutaneous involvement. Therefore, the staging evaluation differs for patients with MF versus patients with other non-Hodgkin's lymphomas and should be tailored to the clinical presentation. Patients who have tumorous or erythrodermic skin involvement have a less favorable prognosis, and patients who present with extracutaneous disease have a poor prognosis. There are multiple therapeutic options for patients with MF and the Sézary syndrome. Selection of a specific treatment plan is based primarily on the clinical stage of the disease. The primary therapy for patients with patch/plaque disease without extracutaneous involvement is a topical regimen, whereas chemotherapy or other aggressive systemic regimens are reserved for those with recalcitrant disease or extracutaneous involvement. There is no evidence that early aggressive systemic therapy is preferable to conservative therapy in the management of limited disease. There are newer combination topical and/or systemic regimens that result in an improved clinical response and possibly a prolonged response duration. For advanced disease, standard therapies are often palliative and successful clinical response is often very short-lived. Therefore, all patients with recalcitrant or extracutaneous disease should be considered for newer investigative therapies.

What is the prognosis for patients who relapse after primary radiation therapy for early-stage low-grade follicular lymphoma?

PURPOSE: To investigate the potential for long-term survival for patients who relapsed after primary radiation therapy (RT) for early-stage low-grade follicular lymphoma and to assess the relative importance of prognostic factors. METHODS AND MATERIALS: Records were reviewed for 79 patients with stage I (n = 32) and II (n = 47) follicular small cleaved cell (fsc, n = 48) and follicular mixed small cleaved cell and large-cell (fmx, n = 31) lymphoma who relapsed after radical RT at Stanford University. Most patients had received doses of 35 to 45 Gy to involved (n = 30) or extended fields (n = 39) or total/subtotal lymphoid irradiation (n = 9). RESULTS: Median time to relapse was 2 years. Most relapses were detected on history (30%) or physical examination (66%). Positive relapse investigations included lymphangiogram (n = 19), chest radiograph (n = 5), and bone marrow biopsy (n = 6). Known extent of relapsed disease was: stage I, n = 30; stage II, n = 26; stage III, n = 10; and stage IV, n = 8. Patients were managed with "watchful waiting" (37%), further RT (39%), chemotherapy [CT, (17%)], or RT + CT (5%). Actuarial survival rates after relapse at 5, 10, 15, and 20 years were 56%, 35%, 17%, and 17% respectively. Median survival was 5.3 years after relapse. Median survival for relapse stage I, II, III, and IV was 10.2, 5.5, 3.0, and 1.1 years respectively. Progression-free survival rates at 5, 10, 15, and 20 years after relapse were 44%, 22%, 22%, and 22% respectively. Factors associated with reduced survival were increasing age, increasing relapse stage, symptoms, histologic transformation and > or = 3 relapse sites. Survival was the same for initial management with "watchful waiting" or RT. CONCLUSION: Approximately 20% of patients experienced prolonged survival after relapse. Younger, asymptomatic patients with stage I-II relapsed disease had the best outcome but results were inferior to those for newly diagnosed stage I-II disease.
