EURAMOS-1, an international randomised study for osteosarcoma: results from pre-randomisation treatment.

BACKGROUND: Four international study groups undertook a large study in resectable osteosarcoma, which included two randomised controlled trials, to determine the effect on survival of changing post-operative chemotherapy based on histological response. PATIENTS AND METHODS: Patients with resectable osteosarcoma aged ≤40 years were treated with the MAP regimen, comprising pre-operatively of two 5-week cycles of cisplatin 120 mg/m(2), doxorubicin 75 mg/m(2), methotrexate 12 g/m(2) × 2 (MAP) and post-operatively two further cycles of MAP and two cycles of just MA. Patients were randomised after surgery. Those with ≥10% viable tumour in the resected specimen received MAP or MAP with ifosfamide and etoposide. Those with <10% viable tumour were allocated to MAP or MAP followed by pegylated interferon. Longitudinal evaluation of quality of life was undertaken. RESULTS: Recruitment was completed to the largest osteosarcoma study to date in 75 months. Commencing March 2005, 2260 patients were registered from 326 centres across 17 countries. About 1334 of 2260 registered patients (59%) were randomised. Pre-operative chemotherapy was completed according to protocol in 94%. Grade 3-4 neutropenia affected 83% of cycles and 59% were complicated by infection. There were three (0.13%) deaths related to pre-operative chemotherapy. At definitive surgery, 50% of patients had at least 90% necrosis in the resected specimen. CONCLUSIONS: New models of collaboration are required to successfully conduct trials to improve outcomes of patients with rare cancers; EURAMOS-1 demonstrates achievability. Considerable regulatory, financial and operational challenges must be overcome to develop similar studies in the future. The trial is registered as NCT00134030 and ISRCTN 67613327.

What is the role of routine follow-up for localised limb soft tissue sarcomas? A retrospective analysis of 174 patients.

BACKGROUND: There are neither prospective data nor agreement on the optimal routine follow-up procedures in patients treated for soft tissue sarcoma of the limb. METHODS: Data on 174 consecutive patients with a soft tissue sarcoma of the limb undergoing follow-up by oncologists at a single centre from 2003 to 2009 were included in this analysis. The rate and site of recurrence and mode of detection were analysed. Outcome of the patients was assessed. RESULTS: Eighty-two patients (47%) experienced relapse of any type. Isolated local recurrence occurred in 26 patients and local relapse with synchronous pulmonary metastases in five patients. Local recurrences were detected clinically in 30 of these 31 patients; magnetic resonance imaging identified only one local recurrence. Twenty-eight patients developed isolated lung metastases; in nine patients these were amenable to resections, seven of whom are currently free of disease after treatment. Lung metastases were detected by chest x-ray (CXR) in 19 patients, computed tomography scanning in 3 patients, and clinically in 11 patients. Twenty-three patients developed non-pulmonary metastases. More than 80% of relapses occurred in the first 2 years of follow-up; however, later recurrences were also observed. CONCLUSIONS: Routine follow-up CXR can detect lung metastases suitable for surgical resection, although the optimal interval of imaging has yet to be defined. Local relapse is almost always detected by patients or physicians, and routine scanning of the primary site is of doubtful benefit. Patient and physician education to detect local relapse may be helpful. Prospective evaluation of follow-up is recommended.

ENCCA WP17-WP7 consensus paper on teenagers and young adults (TYA) with bone sarcomas.

Teenagers and young adults (TYA) cancer contributes substantially to morbidity and mortality in a population with much to offer society. TYA place distinct challenges upon cancer care services, many reporting feeling marginalized and their needs not being met in adult or paediatric cancer services. Bone tumours such as osteosarcoma and Ewing sarcoma, because of their age at presentation and the complexity of their care, are where challenges in managing (TYA) with cancer have often been most readily apparent. Bone sarcomas may be managed by paediatric or medical oncologists, and require fastidious attention to protocol. A lack of recent improvement in survival in TYA with bone tumours may be linked to a lack of specialist care, poor concordance with therapy in some situations and TYA-specific pharmacology. Participation in clinical trials, particularly of young adults, is low, hindering progress. All these requirements may be best met by a concerted effort to create collaborative care between adult and paediatric experts in bone sarcoma, working together to meet TYA patients' needs.

A phase II window study of irinotecan (CPT-11) in high risk Ewing sarcoma: a Euro-E.W.I.N.G. study.

BACKGROUND: The prognosis for patients with nonpulmonary metastatic Ewing sarcoma remains poor with survival in the order of 15-20%. The need to introduce effective new agents into clinical practice is clear. Based on a preclinical rationale of responses in xenografts and backed by a phase I study in children, the Euro-E.W.I.N.G consortium planned a phase II window study of irinotecan in newly diagnosed high risk metastatic patients with Ewing sarcoma. PROCEDURES: Patients were recruited between April 2004 and December 2007. Two courses of irinotecan were administered at a dose of 600 mg/m(2) as a 1 hour infusion at 21 day intervals. Response evaluation was determined after the second course of treatment by radiological assessment of primary and metastatic sites and, where appropriate bone marrow sampling. RESULTS: Twenty-three patients were recruited. Two patients were deemed inevaluable for response. Five patients (24%) demonstrated a partial response. Grade 3 or 4 diarrhoea was seen in 4/43 course of treatment and was managed with loperamide. CONCLUSIONS: This is the first report of single agent irinotecan activity in an untreated population of patients with Ewing sarcoma. In common with other paediatric tumours and other camptothecin analogues such as topotecan, single agent activity is only modest. The exact role for the use of irinotecan in patients with ES, dose schedule and combinations with other agents still requires further investigation.

Survival from high-grade localised extremity osteosarcoma: combined results and prognostic factors from three European Osteosarcoma Intergroup randomised controlled trials.

BACKGROUND: Neoadjuvant chemotherapy improves outcome in osteosarcoma. Determination of optimum regimens for survival, toxicity and prognostic factors requires randomised controlled trials to be conducted. PATIENTS AND METHODS: Between 1983 and 2002, the European Osteosarcoma Intergroup recruited 1067 patients with localised extremity osteosarcoma to three randomised controlled trials. Standard treatment in each was doxorubicin 75 mg/m(2) and cisplatin 100 mg/m(2). Comparators were addition of methotrexate (BO02/80831), a multidrug regimen (BO03/80861) and a dose-intense schedule (BO06/80931). Standard survival analysis methods were used to identify prognostic factors, temporal and other influences on outcome. RESULTS: Five- and 10-year survival were 56% (95% confidence interval 53% to 59%) and 52%, respectively (49% to 55%), with no difference between trials or treatment arms. Median follow-up was 9.4 years. Age range was 3-40 years (median 15). Limb salvage was achieved in 69%. Five hundred and thirty-three patients received the standard arm, 79% completing treatment. Good histological response to preoperative chemotherapy, distal tumour location (all sites other than proximal humerus/femur) and female gender were associated with improved survival. CONCLUSIONS: Localised osteosarcoma will be cured in 50% of patients with cisplatin and doxorubicin. Large randomised trials can be conducted in this rare cancer. Failure to improve survival over 20 years argues for concerted collaborative international efforts to identify and rapidly test new treatments.

Trends in the incidence and survival of cancer in teenagers and young adults: regional analysis for South East England 1960-2002.

AIMS: This study aimed to describe trends in the incidence and survival of cancer in teenagers and young adults in South East England between 1960 and 2002, and the influence of socioeconomic status upon survival. MATERIALS AND METHODS: Data on 1788 patients aged 15-24 years were extracted from the Thames Cancer Registry, assigning each to a diagnostic group using the Birch and Marsden classification. Age-specific incidence rates in 5-year periods for the age groups 15-19 and 20-24 years were calculated for each diagnosis. Five-year relative survival estimates by diagnostic group were calculated for both age groups using 5-year periods of follow-up and non-overlapping years of diagnosis. To calculate overall survival estimates by socioeconomic group, the 10-year follow-up period 1993-2002 was used. RESULTS: Overall incidence rates were 162 per million person-years in 15-19 year olds and 261 in 20-24 year olds. We found a higher overall incidence in males, in 20-24 year olds and an increasing incidence over the last four decades, particularly in this age group. In both the 15-19 and 20-24 years age groups lymphomas were most common. The 5-year relative survival improved for all diagnostic groups, except bone tumours in the older age group, particularly for leukaemia and slightly more for the 20-24 than 15-19 years age group. Teenagers aged 15-19 years and living in more deprived areas had a significantly lower survival than those in more affluent areas. CONCLUSIONS: These findings confirm the increased incidence and improved outcome of cancer in teenagers and young adults. Future analyses should investigate trends in bone tumour survival across regions, survival by socioeconomic status and the influence of specialised care on further improvements in survival.

Myeloablative therapy with autologous bone marrow transplantation as consolidation therapy for recurrent follicular lymphoma.

PURPOSE: To assess myeloablative therapy with autologous bone marrow transplantation (ABMT) in younger patients with follicular lymphoma in the hope of prolonging remission duration and survival. PATIENTS AND METHODS: Since June 1985, 64 patients with follicular lymphoma have received cyclophosphamide (CY) 60 mg/kg x 2 and total-body irradiation (TBI) 2 Gy x 6 supported by ABMT as consolidation of second or subsequent remission. The marrow mononuclear cell (MNC) fraction was treated in vitro with three cycles of the monoclonal antibody (MAb) anti-CD20 and baby rabbit complement before cryopreservation. At the time of treatment, 34 patients were in complete remission (CR), and 30 had residual disease present. RESULTS: The median time to engraftment was 28 days (range, 15 to 46) for both a neutrophil count greater than 0.5 x 10(9)/L and a platelet count greater than 20 x 10(9)/L. Engraftment did not occur in one patient who died at 12 weeks, and three patients (excluded from the range) have had delayed recovery (> 6 months) of RBCs and platelets. Fifty two patients are alive; three died as a consequence of the transplant procedure, two died in remission from other causes, and seven died of recurrent lymphoma. There was a significant correlation between survival and the total number of episodes of treatment required during the course of the illness (< or = to three v > three, P = .01). With a median follow-up duration of 3 1/2 years, 35 patients continue in remission between 1 and 8 years, and 24 have developed recurrent lymphoma, five with evidence of transformation to high-grade histology. Freedom from recurrence did not correlate with the time from diagnosis, the number of previous treatments, the presence or absence of residual disease at the time of treatment, or during which specific remission the treatment was given (second v > second). However, comparison with an age-matched, remission-matched, historical control group shows a significant advantage in favor of treatment with CY plus TBI plus ABMT (P = .001); currently, there is no difference in survival. CONCLUSION: These results are encouraging, although preliminary; it remains to be established whether this treatment prolongs survival.

Patterns of survival in patients with recurrent follicular lymphoma: a 20-year study from a single center.

PURPOSE: To examine outcome of treatment for patients with recurrent follicular lymphoma. PATIENTS AND METHODS: Two hundred twelve newly diagnosed follicular lymphoma patients were studied. One hundred seventy-nine were initially treated successfully. Recurrent or progressive lymphoma developed in 116. Treatment was given according to disease stage and current protocols, mostly with single alkylating agents. A policy of repeated lymph node and bone marrow biopsy was pursued. RESULTS: The overall median survival duration was 9 years, with a median follow-up duration of 12 years. Following recurrence, the median survival duration was 4 1/2 years. Only eight of 116 patients with recurrent disease died of causes unrelated to lymphoma. The overall response rate to first re-treatment was 78% and showed slight decline with successive recurrences, reaching 48% after the fourth treatment. The median duration of second remission was 13 months, (v 31 months for first remission), with the only significant predictive factor being quality of remission. Multivariate analysis showed only age at recurrence and number of prior treatments to correlate with survival after first recurrence. Survival after second remission was only correlated with age and quality of response: Kaplan-Meier estimates gave 53% of patients reaching second complete remission alive 10 years later, compared with 28% in partial remission. CONCLUSION: Age and previous and continuing responsiveness of follicular lymphoma to therapy are the principal determinants of survival following recurrence. Improvement in survival with new treatments will be demonstrated most readily in older patients, while more intensive approaches should be tested in younger patients in whom remission is achieved with difficulty.

Single center experience of a new intensive induction therapy for ewing's family of tumors: feasibility, toxicity, and stem cell mobilization properties.

PURPOSE: To examine the feasibility, tolerability, and toxicity of an intensified induction regimen (vincristine, ifosfamide, doxorubicin, and etoposide [VIDE]) in patients with newly diagnosed Ewing's family of tumors (EFT); to assess ability to maintain dose-intensity, and predictability of peripheral-blood stem cell mobilization. PATIENTS AND METHODS: Thirty patients were treated with vincristine 1.4 mg/m2 (maximum 2 mg) on day 1, doxorubicin 20 mg/m2, ifosfamide 3 g/m2 plus mesna and etoposide 150 mg/m2 on days 1 to 3. Cycles were given every 21 days for up to six cycles. RESULTS: One-hundred and seventy cycles of VIDE were given. The median treatment interval was 21 days (21 to 42) and nadir count: hemoglobin 8.3 (6.3 to 11.9), neutrophils 0.045 (0.0 to 2.1), and platelets 45 (3 to 343). There were 96 episodes of infection requiring hospitalization (56%). Growth factor support reduced infectious complications by 34%. Etoposide dose was reduced, or omitted, in 24% of cycles. Four patients did not complete six cycles due to unacceptable toxicity and one patient progressed on treatment. Twenty patients underwent peripheral-blood stem cell harvesting, 15 after cycle 3, and five after cycle 4. Median CD34+ yield was 4.6 x 106/kg per patient (1.8 to 14.5). Overall response to treatment, measured in 24 patients, was 88%. Seven of 11 patients undergoing surgery achieved greater than 90% necrosis of tumor (64%). CONCLUSION: VIDE is an effective induction regimen with substantial but acceptable toxicity that allows predictable mobilization of stem cells. Maintenance of dose-intensity is feasible in the majority of patients. Growth factors play a role in maintaining dose-intensity and reduce infectious complications.

Short term therapy (STT) for acute myelogenous leukaemia (AML).

Between 1978 and 1988 (median follow up 5 1/2 years), 396 newly diagnosed adults with AML (age range 14-59 years, median 44) received STT comprising daily Adriamycin: 25mg/m2 for 3 days, Cytosine arabinoside (ara-C): 100mg/m2 bd and 6-thioguanine: 100mg/m2 bd, each for 7 days. A maximum of 6 cycles was administered with as short an intercycle time as possible. No further treatment was given. Complete remission (CR) was achieved in 243/396 patients (62%), 71 patients (18%) having resistant leukaemia and 82 (21%) dying within 6 weeks. Antecedent myelodysplasia and advanced age correlated unfavourably with achievement of CR (p = less than 0.001 and 0.005 respectively). Sixty nine patients continue in first remission between 2 1/2 and 12 years; the median duration of remission was 1 year. M3 morphology (p = 0.005) and absence of hepatosplenomegaly (p = 0.001) correlated favourably with duration of remission. Ninety one patients remain alive with an actuarial survival of 22% at 5 years. More recently, additional consolidation comprising high-dose ara-C and total body irradiation (TBI) with autologous bone marrow transplantation (ABMT) has been evaluated in an open study. CR has been achieved in 41/66 patients under the age of 50 but only 19/41 have proceeded to ara-C + TBI + ABMT. Twenty two have not (early recurrence 10, allogeneic BMT 4, debility 6, refusal 2). 11/19 who proceeded to ablative therapy continue in remission (4 treatment related deaths, 4 recurrences) as compared to 9/22 who did not. Currently the overall median duration of remission for the 41 patients intended to proceed is identical to that of age-matched historical controls illustrating the difficulties inherent in demonstrating benefit for the use of myeloablative therapy and ABMT in patients with AML in first remission.

Mitoxantrone and cytosine arabinoside as treatment for acute myelogenous leukemia (AML) at first recurrence.

A total of 107 patients with newly diagnosed acute myeloblastic leukemia (AML) were referred to the ICRF Department of Medical Oncology at St Bartholomew's Hospital between August 1986 and July 1989. Of those referred, 92 (87%) were treated with remission induction chemotherapy comprising: Adriamycin, cytosine arabinoside (ara-C) and 6-thioguanine if aged < 60 years (57 patients) or mitoxantrone (MTN) and ara-C if aged > 60 years (35 patients). Of those treated, 54 (58%) entered complete remission (CR). Recurrent AML developed in 38 out of these 54 patients (70%) of whom 25 aged 19-73 years (median 50 years) subsequently received MTN and ara-C as reinduction therapy. The 19 younger patients (under 60 years old) received MTN at 12 mg/m2, intravenously, daily for 5 days and ara-C at 100 mg/m2, intravenously, twice daily for 7 days. The six older patients received the same ara-C schedule but the dose of MTN was reduced to 10 mg/m2 for 5 days. Second CR was achieved in 16 out of 25 patients (64%) [12/19 (63%) and 4/6 (67%) for patients aged under or over 60 years, respectively]. Eight of the patients in whom second CR was achieved were aged under 50 years and were thus eligible for additional consolidation comprising myeloablative therapy with autologous bone marrow transplantation (ABMT). Four patients actually received the latter treatment: two remain in second CR at 21 and 46 months. Three of the remaining eight patients aged > 50 years in whom second CR was achieved remain in second CR 8 to 43 months later. Censored for myeloablative therapy + ABMT, the overall median duration of second CR was 5 months. Although remissions tended to be short, in younger patients the possibility of proceeding to myeloablative therapy with autologous bone marrow support makes the regimen worthwhile and, even in older patients, it was sometimes possible to achieve prolonged second remissions.

Fatal radiation myelopathy after high-dose busulfan and melphalan chemotherapy and radiotherapy for Ewing's sarcoma: a review of the literature and implications for practice.

Radiation myelopathy is a rare, devastating, late effect of radiotherapy to the spinal cord. Spinal cord tolerance is currently accepted as about 50 Gy in 1.8-2 Gy fractions. However, the effect of chemotherapy on cord tolerance is unclear. This issue is important, given the increasing use of chemotherapy in combination with radiotherapy. We describe the case of a 17-year-old boy with a right apical paraspinal Ewing's tumour in the neck treated with induction chemotherapy, high-dose chemotherapy (busulfan and melphalan) with peripheral stem-cell rescue and, 4 months later, radiotherapy to the primary tumour site (cervical cord received 50 Gy in 30 fractions). After a latent period of 4 months, he developed a progressive, severe and ultimately fatal radiation myelopathy, which we suggest was due to a synergistic interaction between the high-dose chemotherapy and the radiotherapy. The use of such chemotherapy regimens in Ewing's tumours should be carefully considered, particularly when radiotherapy encompassing the spinal cord is an essential component of management.

Trends in survival for teenagers and young adults with cancer in the UK 1992-2006.

BACKGROUND: Although relatively rare, cancer in teenagers and young adults (TYA) is the most common disease-related cause of death and makes a major contribution to years of life lost in this age group. There is a growing awareness of the distinctive needs of this age group and drive for greater understanding of how outcomes can be improved. We present here the latest TYA survival trends data for the United Kingdom (UK). METHODS: Using national cancer registry data, we calculated five-year relative survival for all 15-24 year olds diagnosed with cancer or a borderline/benign CNS tumour in the UK during the periods 1992-1996, 1997-2001 and 2002-2006. We analysed trends in survival for all cancers combined and for eighteen specified groups that together represent the majority of TYA cancers. We compared our data with published data for Europe, North America and Australia. RESULTS: Five-year survival for all cancers combined increased from 75.5% in 1992-1996 to 82.2% in 2002-2006 (P<0.001). Statistically significant improvements were seen for all disease groups except osteosarcoma, rhabdomyosarcoma, non-gonadal and ovarian germ cell tumours and ovarian and thyroid carcinomas. During the earliest time period, females had significantly better survival than males for five of the twelve non-gender-specific disease groups. By the latest period, only melanomas and non-rhabdomyosarcoma soft tissue sarcomas had differential survival by gender. Survival in the UK for the most recent period was generally similar to other comparable countries. CONCLUSION: Five-year survival has improved considerably in the UK for most cancer types. For some disease groups, there has been little progress, either because survival already approaches 100% (e.g. thyroid carcinomas) or, more worryingly for some cancers with poor outcomes, because they remain resistant to existing therapy (e.g. rhabdomyosarcoma). In addition, for a number of specific cancer types and for cancer as a whole males continue to have worse outcomes than females.

Fludarabine in low-grade lymphoma.

During the last 4 years, 88 patients with low-grade non-Hodgkin's lymphoma have received fludarabine, 25 mg/m2 daily for 5 days, repeated every 3 to 4 weeks. Fifty-one patients received fludarabine at recurrence or when the disease was deemed resistant to conventional treatment, 21 patients received the drug in the context of "minimal residual disease" in the hope of complete remission being achieved with a view to proceeding to myeloablative therapy (cyclophosphamide and total body irradiation) with autologous bone marrow transplantation, and 16 newly diagnosed patients received fludarabine as first-line therapy. Myelosuppression was the predominant toxicity, with 55% and 31% of previously treated and newly diagnosed patents, respectively, becoming neutropenic (neutrophils < or = 1.0 X 10(9)/L). The response rate (complete and partial response) was 44% for both patients with recurrent/resistant disease (20 of 45 evaluable patients) and for those with "minimal residual disease" (nine of 20 evaluable patients). In newly diagnosed patients, the response rate was 69% (11 of 16 patients). Five patients died of infection while neutropenic. These results confirm the activity of fludarabine in low-grade non-Hodgkin's lymphoma. Its precise role remains to be determined.

High-dose busulphan/melphalan with autologous stem cell rescue in Ewing's sarcoma.

Eighteen patients with poor risk Ewing's sarcoma (including 11 patients with metastatic disease at presentation) received consolidation therapy of busulphan and melphalan with autologous stem cell rescue. There were nine females. The median age at diagnosis was 14.2 years (range 2.75-30 years). There was one early death due to cytomegalovirus pneumonitis. One patient developed a single generalised convulsion during busulphan therapy. Severe renal toxicity was not encountered. One patient developed veno-occlusive disease of the liver (VOD) which eventually resolved. With a median follow up of 2 years, 13 patients survive including six with initial metastatic disease. We conclude that high-dose busulphan/melphalan is well-tolerated and should be evaluated for efficacy in a larger series of patients with high risk Ewing's sarcoma.

High dose chemotherapy with bone marrow or peripheral stem cell rescue is an effective treatment option for patients with relapsed or progressive Ewing's sarcoma family of tumours.

BACKGROUND: The outcome for patients with recurrent or progressive Ewing's sarcoma family of tumours (ESFT) is poor. High dose therapy (HDT) has been used for a number of years in an attempt to improve survival; however, evidence for the efficacy of this treatment remains limited. PATIENTS AND METHODS: Between 1992 and 2004, 33 patients with recurrent or progressive ESFT were treated with HDT with bone marrow (n=2), peripheral blood stem cell (n=30), or bone marrow and peripheral blood stem cell support (n=1), at a single institution. HDT was with busulphan and melphalan in 22 patients; melphalan and etoposide in seven patients, three with total body irradiation (TBI); melphalan in three patients (2 with TBI), and busulphan and cyclophosphamide in one patient. RESULTS: The 2 and 5 year event free survival was 42.5% (95% CI, 26-59%) and 38.2% (95% CI, 21-55%) respectively. There was one treatment related death from colitis, and grade 4 infection was observed in two patients. CONCLUSIONS: Long-term survival can be attained in patients with recurrent or refractory ESFT treated with HDT. However, this treatment is associated with severe toxicity. A need remains for prospective randomised clinical trials of HDT in this group of patients.

Cerebral metastases from malignant fibrous histiocytoma of bone.

Four patients with malignant fibrous histiocytoma of bone (MFH-B) metastasizing to brain are reported. In two cases, signs of cerebral involvement developed between 4 and 28 months after diagnosis. Both patients had known pulmonary or bony metastases. As a consequence of this experience, two further patients were subsequently identified, one with a definite cerebral metastasis and one who had an asymptomatic supratentorial lesion, possibly metastatic. It is suggested that patients with MFH-B and widespread metastatic disease at presentation or developing within a short interval should undergo cerebral imaging.
