The management of CML in pregnancy is challenging with the need to balance disease control against potential teratogenic effects of TKI therapy. In this multi-center case-cohort study of 16 women in chronic phase, CML ceased TKI treatment pre- or post-conception during their first pregnancy. Thirteen patients were on imatinib; 9 ceased their TKI prior to conception and 7 ceased at pregnancy confirmation.

We sought to determine the utility of surveillance positron emission tomography-computed tomography (PET-CT) in patients with TrIL achieving complete metabolic remission (CMR) after primary therapy. We performed a retrospective analysis of patients with TrIL treated at Peter MacCallum Cancer Centre between 2002 and 2012 who achieved CMR after primary therapy who had ≥1 subsequent surveillance PET-CT.

This issue was addressed in a randomized trial aiming to double the DI of myelosuppressive drugs. Between 1994 and 1999, 250 patients with previously untreated aggressive NHL were randomized to treatment with six cycles of 3-weekly standard (s) or intensive (i) chemotherapy: s-CEOP-cyclophosphamide 750, epirubicin 75, vincristine 1.

Methods: We performed a retrospective review of our database between 2002 and 2009 for patients with de novo DLBCL who underwent surveillance PET-CT after achieving complete metabolic response (CMR) following primary therapy.
Results: Four-hundred and fifty scans were performed in 116 patients, with a median follow-up of 53 (range 8-133) months from completion of therapy.
We report results from a study exploring the combination of romidepsin, bortezomib, and dexamethasone for the treatment of patients with multiple myeloma (MM) previously treated with > 1 prior therapy. The primary objective was to determine the maximum tolerated dose (MTD) of the combination using a novel accelerated dose-escalation schedule in patients with relapsed or refractory MM. The secondary objective was to determine overall response (OR), time to progression (TTP), and overall survival (OS).

However, the presence and significance of prolonged cytopenias after completion of treatment have not been thoroughly quantified.
Methods: Sixty-one patients receiving initial therapy with fludarabine-based regimens were categorised according to the presence of post-treatment cytopenias (haemoglobin <110-130 g/l depending on sex and age, neutrophils <2.
We conducted a trial in 103 patients with newly diagnosed chronic phase chronic myeloid leukemia (CP-CML) using imatinib 600 mg/day, with dose escalation to 800 mg/day for suboptimal response. The estimated cumulative incidences of complete cytogenetic response (CCR) by 12 and 24 months were 88% and 90%, and major molecular responses (MMRs) were 47% and 73%. In patients who maintained a daily average of 600 mg of imatinib for the first 6 months (n = 60), MMR rates by 12 and 24 months were 55% and 77% compared with 32% and 53% in patients averaging less than 600 mg (P = .

Patients And Methods: The records of 28 patients with MCL who had a total of 123 [18F]fluorodeoxyglucose (FDG) PET scans between March 1999 and November 2005 were reviewed. Nine patients had staging scans.
Residual 2-fluoro-2-deoxyglucose (FDG) - positron emission tomography (PET) positivity during treatment of patients with diffuse large B-cell lymphoma (DLBLC) prospectively identifies a subgroup at high likelihood of subsequent treatment failure. A single institution clinical audit of FDG-PET performance for this indication was undertaken for patients with DLBCL treated with anthracycline-based chemotherapy +/- radiotherapy. Of 45 eligible patients, 14 (31%) were PET-positive after a median of three chemotherapy cycles (range 1 - 5), of which 10 (71%) progressed at a median of 6.

Unlike typical hairy cell leukemia (HCL) where the complete response (CR) rate to 2-chlorodeoxyadenosine and 2'-deoxycoformycin can approach about 90%, in HCL-v CR is rare and partial response (PR) occurs in approximately 50% with these agents. Rituximab treatment in relapsed or refractory HCL results in a CR of 13% to 53%, but its use in HCL-v has not been reported in the literature to our knowledge.

In this study, we evaluated the safety and tolerability of a milk-derived growth factor extract (PV701 mouthwash) intended to prevent oral mucositis (OM) after carmustine, etoposide, cytosine arabinoside, and melphalan (BEAM) chemotherapy.

We report a prospective phase II multi-center trial of a modified DICE regimen in relapsed or refractory Hodgkin (HL) or non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL), constituting a single day of intravenous administration followed by 3 days of oral administration, aimed at reducing inpatient days without losing efficacy. Forty patients (median age 56, range 25 - 79) were included: 28 (70%) NHL, 9 (23%) HL and 3 (8%) CLL.

Cytarabine ocfosfate (YNK01) is an oral precursor of cytarabine that may overcome some of the inconvenience and toxicities associated with subcutaneous cytarabine administration.
Patients And Methods: We studied the efficacy and tolerability of combination therapy with interferon-alpha-2b and YNK01 in patients with newly diagnosed, untreated CML.
Objectives: Alemtuzumab (anti-CD52, Campath-1H) has recently been shown to be effective in the treatment of a range of hematological malignancies, including B-cell chronic lymphocytic leukemia and T-cell prolymphocytic leukemia. We undertook a phase II study to evaluate the safety, tolerability and efficacy of alemtuzumab in patients with relapsed or refractory advanced stage cutaneous T-cell lymphoma.
Patients And Methods: A total of eight patients were enrolled, seven with mycosis fungoides/Sézary syndrome (MF/SS) and one with large-cell transformation of MF.
We describe a case of successfully treated multifocal pulmonary Rhizomucor pusillus, a condition which has previously been universally fatal. A 77 year-old man had a background of chronic neutropenia due to hairy-cell leukemia, splenectomy, corticosteroid therapy and an obstructing left ureteric transitional-cell carcinoma. He was successfully treated with 3 months of high-dose liposomal amphotericin B and 7 months of granulocyte-macrophage colony-stimulating factor.

Subjects And Methods: Fifty patients had PET, gallium scanning, and conventional staging of newly diagnosed or progressive Hodgkin's disease or non-Hodgkin's lymphoma. Disease sites, stage, and treatment plans were assessed retrospectively.
The Australian Leukaemia Study Group (ALSG) investigated whether G-CSF would accelerate haemopoietic recovery after induction treatment for acute myeloid leukaemia (AML) intensified with high-dose cytarabine, and therefore improve response rates and survival. Patients were randomised to receive lenograstim (glycosylated recombinant human G-CSF) 5 microg per kg body weight subcutaneously daily from day 8 after starting chemotherapy, or no cytokine, following chemotherapy with cytarabine 3 g/m2 every 12 h on days 1, 3, 5, and 7, together with idarubicin 9 or 12 mg/m2 on days 1, 2, and 3, plus etoposide 75 mg/m2 on days 1 to 7 inclusive. Patients had untreated AML, and were aged 16 to 60 years.

Treatment was reasonably well tolerated with no deaths or intensive care admissions. Despite the advanced phase of disease and heavy pretreatment with cytotoxics and interferon-alfa, 11 of 21 patients (52%) achieved a cytogenetic response.

This randomized crossover study was designed to assess whether a lower dose of G-CSF is as effective as a standard dose of 5 microg/kg daily.
Patients And Methods: Patients who received standard-dose chemotherapy regimens expected to cause neutropenia received G-CSF (lenograstim) that started the day after chemotherapy for 14 days or until the absolute neutrophil count (ANC) recovered to greater than 10 x 10(9)/L.

A reliable measure to predict peripheral blood progenitor cell (PBPC) autograft CD34+ cell content is required to optimize the timing of PBPC collection. We prospectively examined the peripheral blood (PB) CD34+ cell count in 59 consecutive patients with various malignancies and analyzed the correlation between the PB CD34+ cell count and various parameters in the PBPC autograft. Two hundred and thirty-five collections were performed with a median of 4.

However, their prognostic value has not satisfactorily been directly compared to recognised clinical prognostic factors. One hundred and sixty-eight patients with HD had the above markers performed prior to initial treatment.

We describe a 68-year-old patient who presented with such features and developed lytic lesion in the tibia. Based on our case and a review of literature we suggest that cases like ours should be classified and treated as chronic eosinophilic leukemia (a myeloproliferative disorder) rather than as a hypereosinophilic syndrome or as an atypical chronic myeloid leukemia.
