We report a patient who developed orbital MALT lymphoma after autologous peripheral blood stem cell transplantation for follicular lymphoma as relapse of diffuse large B-cell lymphoma. A 54-year-old woman with systemic lymphadenopathy was diagnosed with diffuse large B-cell lymphoma by left supraclavicular lymph node biopsy, and underwent 6 courses of R-CHOP chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone, leading to complete response. Five years later in the follow-up, an abdominal mass with abnormal uptake was found by whole-body 2-[(18)F]fluoro-2-deoxy-D-glucose positron emission tomography, and computed tomography-guided biopsy demonstrated follicular lymphoma...

Viral pneumonias in patients with hematologic malignancies and recipients of hematopoietic stem cell transplantation cause significant morbidity and mortality. Advances in diagnostic techniques have enabled rapid identification of respiratory viral pathogens from upper and lower respiratory tract samples. Lymphopenia, myeloablative and T-cell depleting chemotherapy, graft-versus-host disease, and other factors increase the risk of developing life-threatening viral pneumonia. Chest imaging is often nonspecific but may aid in diagnoses...

BACKGROUND: The intensity of conditioning chemotherapy and radiotherapy in hematopoietic stem cell transplantation (HSCT) varies according to several factors including the patient’s age, pre-existing conditions and performance status. Myeloablative conditioning (MA) increases transplant related mortality and reduces survival in older patients. Reduced intensity conditioning (RIC) is a good option for these patients. AIM: To report our experience with HSCT in patients of different ages with acute leukemia...

A specialized bone marrow microenvironment (niche) regulates hematopoietic stem cell (HSC) self-renewal and commitment. For successful donor-HSC engraftment, the niche must be emptied via myeloablative irradiation or chemotherapy. However, myeloablation can cause severe complications and even mortality. Here we report that the essential amino acid valine is indispensable for the proliferation and maintenance of HSCs. Both mouse and human HSCs failed to proliferate when cultured in valine-depleted conditions...

PURPOSE OF REVIEW: Measurable ('minimal') residual disease in acute myeloid leukemia during first complete morphologic remission (MRD CR1) identifies patients with particularly high relapse risk and short survival. Here, we examine the evidence regarding optimal postremission treatment strategy for such patients. RECENT FINDINGS: With chemotherapy alone or chemotherapy/autologous hematopoietic cell transplantation (HCT), disease recurrence appears inevitable in patients with MRD CR1...

Treating Hodgkin lymphoma by using chemotherapy with or without radiotherapy is highly successful, with substantially fewer deaths from lymphoma than from other causes in recent studies of both early-stage and advanced-stage disease. Long-term toxicity is a major consideration in this context, and recent trials have used functional imaging with [(18)F]fluorodeoxyglucose (FDG) positron emission tomography early in the course of treatment (interim PET) to assess response and modulate subsequent therapy. In early-stage disease, this has allowed omission of consolidation radiotherapy after a good response to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy, and trials have shown that this can be done without detriment to overall survival, despite a small increase in rates of recurrence of ∼5%...

It is necessary to employ myeloablative irradiation or chemotherapy to deplete the HSC niche to optimize hematopoietic stem cell transplantation. In a recent issue of Science, Taya and colleagues provide evidence for an alternative to the toxic chemoirradiative procedure by showing that a valine-restricted diet is sufficient to empty the bone marrow niche.

Primary T-cell lymphoblastic lymphoma (T-LBL) in the eye region is very rare. The present study described a unique case of T-LBL involving the extraocular muscles. A 22-year-old male patient presented with a 3-week history of headache, reduced visual acuity and edema of the left eye. Clinical examination revealed left-sided exophthalmus, periorbital edema, chemosis, and reduced motility of the left eye. A magnetic resonance imaging scan revealed thickening of the left orbital muscles and a positron emission tomography-computed tomography scan also demonstrated activity in a subclavicular lymph node...

Since the early beginnings, in the 1950s, hematopoietic stem cell transplantation (HSCT) has become an established curative treatment for an increasing number of patients with life-threatening hematological, oncological, hereditary, and immunological diseases. This has become possible due to worldwide efforts of preclinical and clinical research focusing on issues of transplant immunology, reduction of transplant-associated morbidity, and mortality and efficient malignant disease eradication. The latter has been accomplished by potent graft-versus-leukemia (GvL) effector cells contained in the stem cell graft...

Solid tumors represent one of the most widespread causes of death in children across the world. Neuroblastoma (NB) constitutes about 8% of all childhood tumors, yet accounts for more than 15% of death, with an unacceptable overall survival rate. Despite the current multimodal therapeutic approaches involving surgery, radiation, chemotherapy with myeloablative therapy and hematopoietic stem cell rescue, there is growing realization of the limitations of conventional agents to improve the outcome in high risk metastatic disease...

Neuroblastoma is the most common extracranial solid tumour occurring in childhood and has a diverse clinical presentation and course depending on the tumour biology. Unique features of these neuroendocrine tumours are the early age of onset, the high frequency of metastatic disease at diagnosis and the tendency for spontaneous regression of tumours in infancy. The most malignant tumours have amplification of the MYCN oncogene (encoding a transcription factor), which is usually associated with poor survival, even in localized disease...

Gonadal dysfunction and infertility are major endocrinological late effects among childhood cancer survivors. Chemotherapy and radiation have gonadotoxic effects and diminish the ovarian reserve. The serum concentration of anti-Müllerian hormone (AMH) is a useful marker of ovarian reserve in survivors. We conducted a longitudinal study to investigate the variations of AMH in evaluating the acute and chronic effects of cancer therapy on the ovary. Three young female patients with different hematological diseases were registered, and their medical records were reviewed...

BACKGROUND: Activating mutations of the receptor tyrosine kinase FLT3 (fms-related tyrosine kinase 3) reflect the most frequent molecular aberration in acute myeloid leukemia (AML). In particular, FLT3 internal tandem duplications (FLT3-ITD) are characterized by an unfavorable prognosis and allogeneic stem cell transplantation (allogeneic SCT) in first complete remission is recommended. In case of imminent or frank relapse following allogeneic SCT, treatment with FLT3 tyrosine kinase inhibitors (TKI) constitutes a promising clinical approach to induce hematologic remission without conventional chemotherapy...

To assess the long-term safety of administering growth hormone (GH) in patients with GH deficiency due to treatment for childhood medulloblastoma and primitive neuroectodermal tumor (PNET). Data were retrospectively retrieved on children receiving GH supplementation, assessing their disease-free and overall survival outcomes and risk of secondary malignancies using Kaplan-Meier and Cox models. Overall 65 children were consecutively collected from May 1981 to April 2013. All patients had undergone craniospinal irradiation (total dose 18-39 Gy), and subsequently received GH for a median (interquartile range, IQR) of 81 (50...

Neuroblastoma is the most common extra-cranial malignancy of childhood, with the highest incidence in children younger than 4 years. The prognosis depends on many factors, such as age at diagnosis, stage of disease and molecular genetic subtype. More than 50% of children who present with the disease are deemed to have high-risk neuroblastoma. The standard therapy for children with high-risk neuroblastoma consists of intensive chemotherapy, surgery, radiotherapy, myeloablative consolidation with autologous haematopoietic stem cell rescue followed by the treatment of minimal residual disease with 13-cis-retinoic acid...

Treosulfan (TREO) has an established position in chemotherapy of advanced ovarian cancer but has been also applied in uveal melanoma patients. Moreover, it is used as an orphan drug for a myeloablative conditioning prior to stem cell transplantation. In this paper, biodistribution of prodrug TREO and its active monoepoxide (S,S-EBDM) and diepoxide (S,S-DEB) into aqueous humor of the eye was studied for the first time. For that purpose, alone TREO and the mixture of TREO, S,S-EBDM and S,S-DEB were administered intravenously to New Zealand White rabbits...

Acute kidney injury and long-term renal dysfunction are common problems following bone morrow transplantation (BMT) and highly related to mortality. The frequency and risk of renal dysfunction are directly related to the method of BMT, with myeloablative allogeneic BMT being associated to the highest risk followed by non-myeloablative allogeneic and myeloablative autologous BMT. The type of BMT is, thus, more important than co-factors such as advanced age, comorbidities, or high baseline serum creatinine. The causes for renal failure are multiple and include chemotherapy and high-dose radiation with fluid loss by diarrhea or vomiting, sepsis or nephrotoxic drugs such as calcineurin inhibitors and antimicrobials...

Gene therapy (GT) approaches based on autologous hematopoietic stem cell (HSC) corrected ex vivo have shown therapeutic benefit in a number of inherited disorders. GT bares the advantage of allowing each patient to be her/his own donor while reducing the risks of immune-mediated complications as compared with allogeneic hematopoietic stem cells transplantation (HSCT). In order to achieve stable engraftment of HSC, patients undergoing transplantation of allogeneic or autologous HSC receive a chemotherapy- and/or radiotherapy-based preparation...

Tumor-specific immune tolerance represents an obstacle for the development of effective anti-tumor immune responses through cancer vaccines. We here evaluated the efficacy of chemo-immunotherapy in breaking tumor-specific immune tolerance in an almost incurable mouse model of spontaneous carcinogenesis.Transgenic HER-2/neu mice bearing large mammary tumors received the adoptive transfer of splenocytes and serum isolated from immune donors, with or without pre-conditioning with cyclophosphamide. Treatment efficacy was assessed by monitoring tumor growth by manual inspection and by magnetic resonance imaging...
