Treatment discontinuation following low-dose TKIs in 248 chronic myeloid leukemia patients: Updated results from a campus CML real-life study. Front Pharmacol 2023; 14:1154377. [PMID: 37033642 PMCID: PMC10076530 DOI: 10.3389/fphar.2023.1154377] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 03/14/2023] [Indexed: 04/11/2023] Open
Abstract
TKIs long-term treatment in CML may lead to persistent adverse events (AEs) that can promote relevant morbidity and mortality. Consequently, TKIs dose reduction is often used to prevent AEs. However, data on its impact on successful treatment-free remission (TFR) are quite scarce. We conducted a retrospective study on the outcome of CML subjects who discontinued low-dose TKIs from 54 Italian hematology centers participating in the Campus CML network. Overall, 1.785 of 5.108 (35.0%) regularly followed CML patients were treated with low-dose TKIs, more frequently due to relevant comorbidities or AEs (1.288, 72.2%). TFR was attempted in 248 (13.9%) subjects, all but three while in deep molecular response (DMR). After a median follow-up of 24.9 months, 172 (69.4%) patients were still in TFR. TFR outcome was not influenced by gender, Sokal/ELTS risk scores, prior interferon, number and last type of TKI used prior to treatment cessation, DMR degree, reason for dose reduction or median TKIs duration. Conversely, TFR probability was significantly better in the absence of resistance to any prior TKI. In addition, patients with a longer DMR duration before TKI discontinuation (i.e., >6.8 years) and those with an e14a2 BCR::ABL1 transcript type showed a trend towards prolonged TFR. It should also be emphasized that only 30.6% of our cases suffered from molecular relapse, less than reported during full-dose TKI treatment. The use of low-dose TKIs does not appear to affect the likelihood of achieving a DMR and thus trying a treatment withdrawal, but might even promote the TFR rate.

European LeukemiaNet 2020 recommendations for treating chronic myeloid leukemia. Leukemia 2020; 34:966-984.

Abstract
The therapeutic landscape of chronic myeloid leukemia (CML) has profoundly changed over the past 7 years. Most patients with chronic phase (CP) now have a normal life expectancy. Another goal is achieving a stable deep molecular response (DMR) and discontinuing medication for treatment-free remission (TFR). The European LeukemiaNet convened an expert panel to critically evaluate and update the evidence to achieve these goals since its previous recommendations. First-line treatment is a tyrosine kinase inhibitor (TKI; imatinib brand or generic, dasatinib, nilotinib, and bosutinib are available first-line). Generic imatinib is the cost-effective initial treatment in CP. Various contraindications and side-effects of all TKIs should be considered. Patient risk status at diagnosis should be assessed with the new EUTOS long-term survival (ELTS)-score. Monitoring of response should be done by quantitative polymerase chain reaction whenever possible. A change of treatment is recommended when intolerance cannot be ameliorated or when molecular milestones are not reached. Greater than 10% BCR-ABL1 at 3 months indicates treatment failure when confirmed. Allogeneic transplantation continues to be a therapeutic option particularly for advanced phase CML. TKI treatment should be withheld during pregnancy. Treatment discontinuation may be considered in patients with durable DMR with the goal of achieving TFR.

Hyper-activation of Aurora kinase a-polo-like kinase 1-FOXM1 axis promotes chronic myeloid leukemia resistance to tyrosine kinase inhibitors. J Exp Clin Cancer Res 2019; 38:216. [PMID: 31122263 PMCID: PMC6533706 DOI: 10.1186/s13046-019-1197-9] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Accepted: 04/25/2019] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Chronic myeloid leukemia (CML) is a myeloproliferative disease caused by the constitutive tyrosine kinase (TK) activity of the BCR-ABL1 fusion protein. Accordingly, TK inhibitors have drastically changed the disease prognosis. However, persistence of the transformed hematopoiesis even in patients who achieved a complete response to TK inhibitors and the disease relapse upon therapy discontinuation represent a major obstacle to CML cure. METHODS Thiostrepton, Danusertib and Volasertib were used to investigate the effects of FOXM1, AKA and Plk1 inhibition in K562-S and K562-R cells. Apoptotic cell death was quantified by annexin V/propidium iodide staining and flow cytometry. Quantitative reverse transcription (RT)-PCR was used to assess BCR-ABL1, FOXM1, PLK1 and AURKA expression. Protein expression and activation was assessed by Western Blotting (WB). Clonogenic assay were performed to confirm K562-R resistance to Imatinib and to evaluate cells sensitivity to the different drugs. RESULTS Here we proved that BCR-ABL1 TK-dependent hyper-activation of Aurora kinase A (AURKA)-Polo-like kinase 1 (PLK1)-FOXM1 axis is associated with the outcome of Imatinib (IM) resistance in an experimental model (K562 cell line) and bone marrow hematopoietic cells. Notably, such a biomolecular trait was detected in the putative leukemic stem cell (LSC) compartment characterized by a CD34+ phenotype. Constitutive phosphorylation of FOXM1 associated with BCR-ABL1 TK lets FOXM1 binding with β-catenin enables β-catenin nuclear import and recruitment to T cell factor/lymphoid enhancer-binding factor (TCF/LEF) transcription complex, hence supporting leukemic cell proliferation and survival. Lastly, the inhibition of single components of AURKA-PLK1-FOXM1 axis in response to specific drugs raises the expression of growth factor/DNA damage-inducible gene a (GADD45a), a strong inhibitor of AURKA and, as so, a critical component whose induction may mediate the eradication of leukemic clone. CONCLUSIONS Our conclusion is that AURKA, PLK1 and FOXM1 inhibition may be considered as a promising therapeutic approach to cure CML.

Abstract
Background High-dose chemotherapy (HDC) with hematopoietic progenitor cell transplantation is a standard option for relapsed/refractory testicular germ-cell tumor (GCT), but only few data have been reported in female patients with GCT. We conducted a retrospective analysis of female patients with GCT treated with HDC and registered with the European Society for Blood and Marrow Transplantation. Patients and methods Between 1985 and 2013, 60 registered female patients with GCT, median age 27 years (range 15-48), were treated with salvage HDC. Forty patients (67%) had primary ovarian GCT, 8 (13%) mediastinal, 7 (12%) retroperitoneal and 5 (8%) other primary sites/unknown. Twenty-two patients (37%) received HDC as second-line therapy, 29 (48%) as third-line, and 9 (15%) as fourth- to sixth-line. Nine of 60 patients (15%) received HDC as late-intensification with no evidence of metastasis before HDC. The conditioning HDC regimens comprised carboplatin in 51 of 60 cases (85%), and consisted of a single HDC cycle in 31 cases (52%), a multi-cycle HDC regimen in 29 (48%). Results Nine cases who underwent late intensification HDC were not evaluable for response. Of the other 51 assessable patients, 17 (33%) achieved a complete response (CR), 8 (16%) a marker-negative partial remission (PRm-), 5 (10%) a marker-positive partial remission, 5 (10%) stable disease, and 13 (25%) progressive disease. There were 3 toxic deaths (6%). With an overall median follow-up of 14 months (range 1-219), 7 of 9 (78%) patients with late intensification and 18 of the 25 patients (72%) achieving a CR/PRm- following HDC were free of relapse/progression. In total, 25 of 60 patients (42%) were progression-free following HDC at a median follow-up of 87 months (range 3-219 months). Conclusions Salvage HDC based on carboplatin represents a therapeutic option for female patients with relapsed/refractory GCT.

Abstract
Primary lymphoma of the central nervous system (CNS) represents a pathology that is no longer considered rare, also in the light of its high correlation with the human immunodeficiency virus (HIV) syndrome reported recently. Often the correct diagnosis of the disease is difficult to reach, owing to the wide spectrum of non-lymphoma pathologies from which it should be differentiated and the invasiveness of some diagnostic techniques. The biologic aggressiveness of the neoplasm often makes a combined radio-chemotherapeutic approach necessary. In contrast, surgical resection does not seem to provide any significant benefit. The clinical experience reported here, together with a review of the most recent literature, lead the authors to suggest the opportunity of treating primary lymphoma of the CNS with the most active and modern chemotherapeutic protocols in association with traditional treatments to obtain an improvement in overall survival.

Abstract
To explore the clinical applicability of the Goldie and Coldman hypothesis, we treated 28 patients with metastatic breast cancer with alternating non-cross-resistant chemotherapy. The patients received cyclophosphamide, 600 mg/m2, 5-fluorouracil, 600 mg/m2, methotrexate, 40 mg/m3, alternated every three weeks with adriamycin, 60 mg/m2, and mitomycin C, 10 mg/m2. Only one patient had previously received palliative chemotherapy. Six patients had received adjuvant CMF, and 17 patients had been pretreated with endocrine therapy (13 for advanced disease, 4 as adjuvant). Fourteen patients had bone involvement, and 10 had visceral metastases. A mean of 12 cycles was given to 24 evaluable patients. The objective response rate was 67%: 11 patients (46%) achieved complete and 5 (21%) partial remission. Response rate in soft tissues was 83.3%, in bone 50%, in liver 100%, and in lung 80%. The median duration of response was 14 months, with 7 patients still in remission. No life-threatening toxicity was observed. Our preliminary results support the validity of this approach and the efficacy of this combination chemotherapy. A large-scale randomized study is warranted.

Abstract
Two patients with germ cell testicular cancer were submitted to radioimmunotherapy (RIT) by using the monoclonal antibody 131I-radiolabelled (MoAb) H17E2, raised against placental alkaline phosphatase (PLAP). Both patients had been previously treated with repeated chemotherapy regimens assisted by autologous bone marrow transplant (ABMT), that, in the end were unsuccessful, thus necessitating further experimental treatment. RIT was well tolerated and the targeting of multiple neoplastic lesions was satisfactory. Nevertheless, the clinical results of treatment were minimal owing to the extension of the tumour. The data obtained suggest the possibility of applying this form of treatment in patients with minimal residual disease after previous traditional chemotherapy regimens.

Abstract
Bone marrow biopsies by Jamshidi needle were performed in 106 breast cancer female patients. Sixty-four of them were in follow-up after mastectomy, and neoplastic involvement of marrow was found in 21 patients (32.8%). Among the 42 women undergoing staging before mastectomy, the incidence of marrow involvement was 11.9% (5 women, all with radiographic positivity). Of the 37 women, either in follow-up or in the staging phase, with bone metastases detected by roentgenographic and isotopic examination, the bone biopsy was positive in 23 (62.1%), and 7 histologically had micrometastases. Three women, without any radiographic or isotopic sign of metastases, had positive biopsies. A good correlation was found between the hydroxyproline:creatinine ratio and neoplastic involvement of bone marrow.

Abstract
About 40% of patients with advanced cancer develop metastases in the central nervous system (CNS), mainly from primary tumors of lung, breast and melanoma. In most of cases there are multiple CNS metastases, making surgery or localized radiosurgery not feasible. The current standard of care for these patients is radiation therapy, which can improve neurologic symptoms but does not have any impact on the patient's overall survival. Temozolomide, capecitabine and gefitinib are safe and active in the treatment of CNS metastases from melanoma/recurrent gliomas, breast carcinoma and lung cancer, respectively. New, orally administered drugs hold a great potential for patients with CNS metastases.

Abstract
Most reports on chronic myeloid leukaemia (CML) treatment with tyrosine kinase inhibitors (TKIs) focus on efficacy, particularly on molecular response and outcome. In contrast, adverse events (AEs) are often reported as infrequent, minor, tolerable and manageable, but they are increasingly important as therapy is potentially lifelong and multiple TKIs are available. For this reason, the European LeukemiaNet panel for CML management recommendations presents an exhaustive and critical summary of AEs emerging during CML treatment, to assist their understanding, management and prevention. There are five major conclusions. First, the main purpose of CML treatment is the antileukemic effect. Suboptimal management of AEs must not compromise this first objective. Second, most patients will have AEs, usually early, mostly mild to moderate, and which will resolve spontaneously or are easily controlled by simple means. Third, reduction or interruption of treatment must only be done if optimal management of the AE cannot be accomplished in other ways, and frequent monitoring is needed to detect resolution of the AE as early as possible. Fourth, attention must be given to comorbidities and drug interactions, and to new events unrelated to TKIs that are inevitable during such a prolonged treatment. Fifth, some TKI-related AEs have emerged which were not predicted or detected in earlier studies, maybe because of suboptimal attention to or absence from the preclinical data. Overall, imatinib has demonstrated a good long-term safety profile, though recent findings suggest underestimation of symptom severity by physicians. Second and third generation TKIs have shown higher response rates, but have been associated with unexpected problems, some of which could be irreversible. We hope these recommendations will help to minimise adverse events, and we believe that an optimal management of them will be rewarded by better TKI compliance and thus better CML outcomes, together with better quality of life.

Abstract
The aim of this study was to investigate the effects of a non-standard, intermittent imatinib treatment in elderly patients with Philadelphia-positive chronic myeloid leukaemia and to answer the question on which dose should be used once a stable optimal response has been achieved. Seventy-six patients aged ⩾65 years in optimal and stable response with ⩾2 years of standard imatinib treatment were enrolled in a study testing a regimen of intermittent imatinib (INTERIM; 1-month on and 1-month off). With a minimum follow-up of 6 years, 16/76 patients (21%) have lost complete cytogenetic response (CCyR) and major molecular response (MMR), and 16 patients (21%) have lost MMR only. All these patients were given imatinib again, the same dose, on the standard schedule and achieved again CCyR and MMR or an even deeper molecular response. The probability of remaining on INTERIM at 6 years was 48% (95% confidence interval 35-59%). Nine patients died in remission. No progressions were recorded. Side effects of continuous treatment were reduced by 50%. In optimal and stable responders, a policy of intermittent imatinib treatment is feasible, is successful in about 50% of patients and is safe, as all the patients who relapsed could be brought back to optimal response.

Abstract
For almost 10 years imatinib has been the therapeutic standard of chronic myeloid leukemia. The introduction of other tyrosine kinase inhibitors (TKIs) raised a debate on treatment optimization. The debate is still heated: some studies have protocol restrictions or limited follow-up; in other studies, some relevant data are missing. The aim of this report is to provide a comprehensive, long-term, intention-to-treat, analysis of 559 newly diagnosed, chronic-phase, patients treated frontline with imatinib. With a minimum follow-up of 66 months, 65% of patients were still on imatinib, 19% were on alternative treatment, 12% died and 4% were lost to follow-up. The prognostic value of BCR-ABL1 ratio at 3 months (⩽10% in 81% of patients) was confirmed. The prognostic value of complete cytogenetic response and major molecular response at 1 year was confirmed. The 6-year overall survival was 89%, but as 50% of deaths occurred in remission, the 6-year cumulative incidence of leukemia-related death was 5%. The long-term outcome of first-line imatinib was excellent, also because of second-line treatment with other TKIs, but all responses and outcomes were inferior in high-risk patients, suggesting that to optimize treatment results, a specific risk-adapted treatment is needed for such patients.

Abstract
BACKGROUND The incidence of chronic myeloid leukemia (CML) increases with age, but it is unclear how the characteristics of the disease vary with age. In children, where CML is very rare, it presents with more aggressive features, including huge splenomegaly, higher cell count and higher blast cell percentage. PATIENTS AND METHODS To investigate if after childhood the disease maintains or loses these characteristics of aggressiveness, we analyzed 2784 adult patients, at least 18 years old, registered by GIMEMA CML WP over a 40-year period. RESULTS Young adults (YAs: 18-29 years old) significantly differed from adults (30-59 years old) and elderly patients (at least 60 years old) particularly for the frequency of splenomegaly (71%, 63% and 55%, P < 0.001), and the greater spleen size (median value: 4.5, 3.0 and 1.0 cm, P < 0.001). According to the EUTOS score, that is age-independent, high-risk patients were more frequent among YAs, than among adult and elderly patients (18%, 9% and 6%, P < 0.001). In tyrosine kinase inhibitors-treated patients, the rates of complete cytogenetic and major molecular response were lower in YAs, and the probability of transformation was higher (16%, 5% and 7%, P = 0.011). CONCLUSIONS The characteristics of CML or the host response to leukemia differ with age. The knowledge of these differences and of their causes may help to refine the treatment and to improve the outcome. CLINICAL TRIAL NUMBERS NCT00510926, NCT00514488, NCT00769327, NCT00481052.

Testicular cancer (TC) is the most common neoplasm in males aged 15-40 years. The majority of patients have no evidence of metastases at diagnosis and thus have clinical stage I (CSI) disease [Oldenburg J, Fossa SD, Nuver J et al. Testicular seminoma and non-seminoma: ESMO Clinical Practice Guidelines for diagnosis, treatment and follow-up. Ann Oncol 2013; 24(Suppl 6): vi125-vi132; de Wit R, Fizazi K. Controversies in the management of clinical stage I testis cancer. J Clin Oncol 2006; 24: 5482-5492.]. Management of CSI TC is controversial and options include surveillance and active treatment. Different forms of adjuvant therapy exist, including either one or two cycles of carboplatin chemotherapy or radiotherapy for seminoma and either one or two cycles of cisplatin-based chemotherapy or retroperitoneal lymph node dissection for non-seminoma. Long-term disease-specific survival is ∼99% with any of these approaches, including surveillance. While surveillance allows most patients to avoid additional treatment, adjuvant therapy markedly lowers the relapse rate. Weighing the net benefits of surveillance against those of adjuvant treatment depends on prioritizing competing aims such as avoiding unnecessary treatment, avoiding more burdensome treatment with salvage chemotherapy and minimizing the anxiety, stress and life disruption associated with relapse. Unbiased information about the advantages and disadvantages of surveillance and adjuvant treatment is a prerequisite for informed consent by the patient. In a clinical scenario like CSI TC, where different disease-management options produce indistinguishable long-term survival rates, patient values, priorities and preferences should be taken into account. In this review, we provide an overview about risk factors for relapse, potential benefits and harms of adjuvant chemotherapy and active surveillance and a rationale for involving patients in individualized decision making about their treatment rather than adopting a uniform recommendation for all.

Abstract
The introduction of tyrosine kinase inhibitors (TKI) in the treatment of Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) has revolutionized the outcome, but the prognosis of the disease is still based on prognostic systems that were developed in the era of conventional chemotherapy and interferon (IFN)-alfa. A new prognostic score including only two variables, spleen size and basophils, was developed for the prediction of complete cytogenetic response (CCyR) and progression-free survival (PFS). The score was based on a large series of patients who were enrolled in prospective multicenter studies of first-line imatinib treatment. The prognostic value of the EUTOS (European Treatment and Outcome Study for CML) score has now been tested in an independent, multicenter, multinational series of 1288 patients who were treated first-line with imatinib outside prospective studies. It was found that also in these patients, the EUTOS prognostic score was predictive for CCyR, PFS and overall survival (OS). In addition, the prognostic value of the score was reported to be significant in seven of the eight other independent studies of almost 2000 patients that were performed in Europe, the Americas and Asia. The EUTOS risk score is a valid tool for the prediction of the therapeutic effects of TKI, particularly imatinib.

Abstract
BACKGROUND An early serum tumor marker (TM) decline during chemotherapy was shown to independently predict survival in patients with poor-prognosis disseminated non-seminomatous germ-cell tumors (NSGCTs). The aim of this study was to assess whether a TM decline (TMD) also correlates with the outcome in the salvage setting. PATIENTS AND METHODS Data regarding 400 patients with progressive or relapsed disseminated NSGCTs after first-line chemotherapy prospectively accrued onto two phase III clinical trials were obtained. Serum alpha-fetoprotein (AFP) and/or human chorionic gonadotropin (hCG) were assessed at baseline and after 6 weeks of chemotherapy. A total of 297 patients, 185 and 112 in the training and validation sets, with initially abnormal TMs for whom a change from baseline could be established were used for this analysis. RESULTS An unfavorable decline in either AFP or hCG was predictive of progression-free survival (PFS) [hazard ratio, HR = 2.15, (95% CI 1.48-3.11); P < 0.001; 2-year PFS rate: 50% versus 26%] as was the Lorch prognostic score (LPS). In the multivariate analysis, an unfavorable TMD, stratified based on the LPS, was an independent adverse prognostic factor for PFS and OS. CONCLUSION An unfavorable TMD during the first 6 weeks after chemotherapy is associated with a poorer outcome in patients with relapsed disseminated NSGCTs.

Abstract
In November 2011, the Third European Consensus Conference on Diagnosis and Treatment of Germ-Cell Cancer (GCC) was held in Berlin, Germany. This third conference followed similar meetings in 2003 (Essen, Germany) and 2006 (Amsterdam, The Netherlands) [Schmoll H-J, Souchon R, Krege S et al. European consensus on diagnosis and treatment of germ-cell cancer: a report of the European Germ-Cell Cancer Consensus Group (EGCCCG). Ann Oncol 2004; 15: 1377-1399; Krege S, Beyer J, Souchon R et al. European consensus conference on diagnosis and treatment of germ-cell cancer: a report of the second meeting of the European Germ-Cell Cancer Consensus group (EGCCCG): part I.

European consensus conference on diagnosis and treatment of germ-cell cancer: a report of the second meeting of the European Germ-Cell Cancer Consensus group (EGCCCG): part II. Eur Urol 2008; 53: 497-513]. A panel of 56 of 60 invited GCC experts from all across Europe discussed all aspects on diagnosis and treatment of GCC, with a particular focus on acute and late toxic effects as well as on survivorship issues. The panel consisted of oncologists, urologic surgeons, radiooncologists, pathologists and basic scientists, who are all actively involved in care of GCC patients. Panelists were chosen based on the publication activity in recent years. Before the meeting, panelists were asked to review the literature published since 2006 in 20 major areas concerning all aspects of diagnosis, treatment and follow-up of GCC patients, and to prepare an updated version of the previous recommendations to be discussed at the conference. In addition, ∼50 E-vote questions were drafted and presented at the conference to address the most controversial areas for a poll of expert opinions. Here, we present the main recommendations and controversies of this meeting. The votes of the panelists are added as online supplements.

Abstract
Background: Optimal adherence to imatinib therapy is of paramount importance to maximise treatment effectiveness in patients with chronic myeloid leukaemia (CML). The main objective of this study was to investigate patient-reported personal factors associated with adherence behaviour. Methods: Analysis was conducted on 413 CML patients receiving long-term therapy with imatinib. Adherence behaviour was measured with the Morisky Medication Adherence Scale and personal factors investigated included: quality of life, perceived social support, fatigue, symptom burden, psychological wellbeing and desire for additional information. Key socio-demographic and treatment-related factors were also taken into account. Univariate and multivariate logistic regression analyses were used to investigate factors associated with optimal adherence to therapy. Results: In all, 53% of patients reported an optimal adherence behaviour. The final multivariate model retained the following variables as independent predictors of optimal adherence to therapy: desire for more information (ref. no), odds ratio (OR)=0.43 (95% confidence interval (CI), 0.29–0.66; P<0.001), social support (higher score representing greater support), OR=1.29 (95% CI, 1.11–1.49; P<0.001) and concomitant drug burden (ref. no), OR=1.82 (95% CI, 1.18–2.80; P=0.006). Conclusion: This study suggests that a higher level of social support, satisfaction with information received and concomitant drug burden are the main factors associated with greater adherence to long-term imatinib therapy.

Abstract
The median survival of women with metastatic breast cancer (MBC) is 18-24 months, and fewer than 5% are alive and disease free at 5 years. We report toxicity and survival in a cohort of MBC patients receiving high-dose chemotherapy (HDC) with autologous hematopoietic SCT (AHSCT) in Italy between 1990 and 2005. Data set for survival analysis has been obtained for 415 patients. Clinical parameters including probability of transplant-related mortality (TRM), PFS and OS. With a median follow-up of 27 months (range 0-172), OS and PFS at 5 and 10 years in the whole population were 47/23 and 32/14%, respectively. A total 239 patients are alive with a median follow-up of 33 months (range 2-174). Survival was significantly more pronounced in patients harboring hormone receptor positive tumors (P=0.028), without visceral metastases (P=0.009) and in women with chemosensitive disease (P<0.0001). Sixty eight patients (20.4%) who received HDC in partial response, stable or progressive disease underwent conversion to CR. TRM was 2.5% overall and 1.3% since 2000. Our findings suggest that could be a role for HDC and AHSCT in delaying disease progression and possibly cure a subset of MBC patient harboring chemosensitive tumors.

Abstract
BACKGROUND Based on the high chemosensitivity of germ-cell tumors (GCTs), the concept of high-dose chemotherapy (HDCT) has been developed worldwide and investigated through many clinical trials. It has been carried out in different clinical settings, ranging from resistant or absolute refractory disease to chemosensitive relapse. HDCT with stem-cell support has been also explored as a part of first-line strategy for poor-prognosis patients. PATIENTS AND METHODS Our review summarized results from clinical trials evaluating the role of HDCT in patients with advanced GCTs. So far available data were obtained through a Medline search of English-language literature. RESULTS Several phase II trials and retrospective series have shown a possible benefit for GCT patients with recurrent disease as well as in first-line setting. Despite these results, data derived from randomized phase III studies failed to demonstrate any survival advantage for HDCT over conventional chemotherapy. CONCLUSIONS The role of HDCT in GCTs remains controversial. We need new prospective studies based on prognostic factors with multiple transplants of carboplatin and etoposide as the preferred high dose regimen. At present, based mainly on retrospective and phase II studies, HDCT may represent a therapeutic option for patients with primary refractory disease or for those with a second or further relapse.

Abstract
BACKGROUND AND OBJECTIVES Opioid-bowel dysfunction (OBD) is a broad range of symptoms potentially associated with opioid therapy. This prospective, multicentric study assesses the prevalence of OBD in patients on analgesic therapy for the treatment of pain from any cause and identifies the factors associated with the onset of this side effect. MATERIALS AND METHODS Consecutive patients aged > 18 years, on analgesic treatment with opioids, non-steroidal anti-inflammatory drugs (NSAIDs) or other therapies for chronic pain of any aetiology were included in the study. The association of OBD with gender, age, pain aetiology and analgesic treatment was analyzed by multivariate analysis and logistic analysis. RESULTS In total, 2324 patients were included in the study. The prevalence of OBD symptoms was 63.5%, despite that the wide majority of patients (89.5%) were receiving laxatives. OBD symptoms were judged as directly correlated with analgesic therapy in 85.1% of cases. The highest prevalence of constipation was reported with morphine, whereas the lowest was observed in patients on oxycodone CR and buprenorphine TTS. Statistical analysis showed that patients on opioids have a higher likelihood of experiencing OBD symptoms than those on NSAIDs or other treatments (66.2% vs 37.0%), and this probability is even higher in those with cancer-related pain (69.3%). Female gender and age > 70 years also appeared as risk factors. The logistic analysis indicated that cancer-related pain, increased age and the use of fentanyl are positive predictors of the presence of OBD, whereas the administration of oxycodone CR was associated with a decreased incidence of these symptoms. DISCUSSION Even with the limitation of any observational experience, this study suggests, for the first time, the existence of some factors predictive of the onset of OBD symptoms in patients on analgesic treatment. Moreover, different opioids seem to be associated with a different risk of experiencing these symptoms.

Abstract
7074 Background: Nilotinib has a higher binding affinity and selectivity for Abl with respect to imatinib (IM). To investigate the efficacy and the safety of nilotinib 400 mg BID in untreated, early chronic phase (ECP) CML patients (pts), the GIMEMA CML WP is conducting a multicentric, phase II study trial (ClinicalTrials.gov NCT00481052 ). Methods: 73 pts have been enrolled between June 2007 and February 2008. The median age was 51 years (range 18–83). Median follow-up is currently 210 days (range 68–362). Results: All 73 pts and 48/73 (66%) completed 3 and 6 months on treatment, respectively. Response at 3 and 6 months (ITT): CHR rate was 100% and 98%, CCgR rate 78% and 96%, respectively. A MMR was achieved by 3% after 1 month on treatment, but this proportion rapidly increased to 22% after 2 months, 59% after 3 months and 74% after 6 months. One patient progressed at 6 months to accelerated-blastic phase with the T315I mutation. The median daily average dose was close to the intended dose, 789 mg (range 261 - 800); 34/73 pts (47%) interrupted nilotinib at least once, with a median interruption of 15 days (range 2–98). The dose of nilotinib at the last visit was 400 mg BID for 52 pts (71%), 400 mg daily for 20 pts (27%), and 200 mg daily for 1 patient (1%). AEs (grade 3/4) were manageable with appropriate dose adaptations: hematologic toxicity was recorded so far in 4 pts (5%); the most frequent biochemical laboratory abnormalities (grade 3) were total bilirubin increase (15%), GOT/GPT increase (11%), and lipase increase (4%). Only 1 episode of grade 4 lipase increase was recorded. It is noteworthy, considering the 48 cases with at least 6 months of follow-up, that the incidence of any grade 2 and 3 non-hematologic adverse event, decreased from 50% and 8% (first 3 months) to 23% and 6% (second trimester), respectively. In 16 pts (22%), transient and not clinically relevant ECG abnormalities have been recorded; 2 more pts (3%) revealed a transient and uneventful QTc prolongation (>450 but <499 msec). Conclusions: In ECP Ph-pos CML pts both cytogenetic and molecular responses to nilotinib are substantially faster than the responses to IM. Supported by: FIRB 2006.

Abstract
5086 Background: Early serum tumor marker decline during chemotherapy was previously shown to be prognostic for progression-free survival (PFS) and overall survival (OS) in patients with relapsed GCT in an analysis of the IT94 phase III trial, which compared conventional chemotherapy versus high dose chemotherapy (Massard C, ASCO 2008. Abstract No. 5085). The aim of this study was to validate this concept in an independent set of patients. Methods: Data on tumor site, response to first line chemotherapy, serum tumor markers at baseline and after two cycles of chemotherapy were obtained from 235 patients accrued in the IT94 trial (training set) and from 181 patients included in phase III prospective trials of high-dose chemotherapy conducted by the German GCT group (Lorch et al, J Clin Oncol. 2007) (validation set). The change from baseline of serum alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG) was assessed and classified into ‘favorable marker decline‘ and ‘unfavorable marker decline‘ group, as previously described (ASCO 2008. Abstract No. 5085). Results: In both series, favourable serum AFP decline was significantly associated with a better 2-year PFS (46% vs 24%; p < 0.0001) and OS (62% vs 34%; p = 0.0013) while serum hCG decline did not affect outcome. In multivariate analysis of the IT94 trial, an unfavorable AFP decline and a mediastinal primary site were adverse prognostic factors for both PFS and OS, and this was confirmed in the validation set. Among patients from the good prognostic group (favorable AFP decline and non-mediastinal primary site), those who were treated with high-dose chemotherapy had a better PFS (2-year PFS rate: 54% vs 37%; HR = 0.62; p = 0.017), and a trend for a better OS (2-year OS rate: 68% vs. 58%; HR = 0.77; p = 0.29) as compared to patients who were treated with conventional chemotherapy. In contrast, there was no difference in outcome in patients from the poor prognostic group (unfavourable AFP decline and/or mediastinal primary site), whether they received conventional chemotherapy or high-dose chemotherapy. Conclusions: AFP decline during the first 6 weeks of salvage chemotherapy and a mediastinal primary tumor site predict for PFS and OS in patients with relapsed disseminated GCT. No significant financial relationships to disclose.

Abstract
A system to purge the bone marrow of myeloma cells has been developed in our laboratories with the aim of treating with myeloablative radiochemotherapy patients suffering from advanced multiple myeloma. This system is based on the ex vivo incubation of the marrow with an immunotoxin composed of the 8A monoclonal antibody--that recognizes plasma cells and B-cell precursors--and the ribosome-inactivating protein momordin. 8 patients have so far been treated. 4 are surviving from 4 to 18 months after ABMT, whereas 4 died after 1 to 6 months, 2 from infections, 1 from relapsing disease and 1 from veno-occlusive disease. A marked tumour reduction was observed in all evaluable patients; however, none has achieved complete disappearance of the disease. The haemopoietic reconstitution was significantly delayed in 3 patients. These preliminary results show the feasibility of this approach in advanced MM patients with heavily infiltrated marrow. The place of ABMT in the treatment of MM remains to be determined; the selection of patients with still responding and less advanced disease would probably produce better results.

Abstract
17 patients with multiple myeloma (MM) received marrow transplants from their HLA-matched, MLC-negative sibling donors. 9 patients had progressive disease not responding to conventional treatments, while the other 8 patients were rated as responders. The most frequently used conditioning regimen consisted of total body irradiation and high-dose, multi-agent chemotherapy with cyclophosphamide plus either oral melphalan (5 cases) or BCNU (1 case) on both these drugs (7 cases). 12 patients were evaluable for response to BTM: 7 of them (6 responders and 1 with advanced refractory MM) entered complete remission, while 5 had a sustained decrease in tumor mass that ranged between 72% and 93%. 11 patients died of transplant-related causes, 1 of them with signs of progressive disease. The remaining 6 patients are alive and 5 of them maintain a complete remission status 4 to 67 (median 36) months after BMT. It is concluded that therapeutic benefits of transplantation in MM are still offset by the high mortality related to the procedure. A more accurate selection of patients who would most benefit from BMT and performing transplant at an earlier phase of the disease are warranted before major advances can be made in the cure of these patients.
