1/11. Malignant melanoma occurring within a previously irradiated area.The commonest radiation-induced neoplasms are sarcomas. Ionizing radiation is not usually associated with the development of malignant melanoma. We report two patients with malignant melanoma occurring within a previously irradiated area. There is evidence to support radiation in the pathogenesis of melanoma but the family histories, especially in one patient, suggest that genetic mutations may also have played a role, particularly in relation to the short latent period.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
2/11. smooth muscle tumor developing in an immunocompromised child after therapy for leukemia.We report a 5.5-year-old boy who underwent autologous peripheral blood stem cell transplantation for high-risk acute lymphoblastic leukemia and who had two abdominal masses develop 6 months later. Macroscopically complete resection of the abdominal tumors was performed and revealed a well-differentiated leiomyosarcoma. Smooth muscle tumors, benign or malignant, are increasingly recognized in children with various immunodeficiencies; the association with acute lymphoblastic leukemia is rarely described.- - - - - - - - - - ranking = 0.0083474076462023keywords = leukemia (Clic here for more details about this article) |
3/11. leiomyosarcoma in poland's syndrome. A case report.We describe a 56-year-old female with absence of the right pectoralis muscles, aplasia of the right breast, and skeletal deformities of the right hand, typical of poland's syndrome. Following complaints of lower abdominal pain, a CT examination revealed an 8-cm mass in the right anterior pelvic wall. Surgical resection of the mass revealed a high-grade, poorly differentiated leiomyosarcoma. poland's syndrome is known to be associated with a high incidence of leukemia but this is the first description of its association with leiomyosarcoma. Although we cannot exclude the possibility of a chance association, it is reasonable to assume that, similar to other syndromes with multiple congenital anomalies, the association with an increased incidence of malignancy is an integral part of the underlying genetic abnormality.- - - - - - - - - - ranking = 0.0013912346077004keywords = leukemia (Clic here for more details about this article) |
4/11. Postradiotherapy intratesticular leiomyosarcoma.We report what we believe to be the first case of high-grade, radiation-induced, intratesticular leiomyosarcoma in a 30-year-old man who had had testicular relapse of acute lymphoblastic leukemia at age 12 years that was treated with standard testicular field radiation (2400 cGy) and chemotherapy. radiation-induced tumors of this type are rare, have a median latency of 10 years, and are usually dose dependent (around 5000 cGy). Testicular leiomyosarcoma, especially high grade, remains to be fully characterized. After radical orchiectomy, patients should be followed up with serial germ cell tumor markers and imaging to monitor for metastatic spread. The use of retroperitoneal lymph node dissection and chemotherapy remains controversial but is probably not indicated.- - - - - - - - - - ranking = 1.0013912346077keywords = radiation-induced, leukemia (Clic here for more details about this article) |
5/11. Metastatic disease in the breast from nonmammary neoplasms.breast cancer is the leading cause of death from cancer in women. The metastatic involvement of the breast from nonmammary neoplasms is a relatively rare condition. female patients are affected five to six times more frequently than male patients. We present seven patients with metastasis in the breast from extramammary tumors. Females seemed to be more frequently affected (6 women and 1 man) and included a wide range of ages (17-70 years old). All female patients had suspicious-looking abnormalities (B1-RADS 4) or lesions highly suspicious of malignancy (BI-RADS 5) in the mammography, without a confirmative fine needle aspiration cytology. The primary malignancies were equally distributed between non-hematological (1 renal adenocarcinoma, 1 melanoma, 1 leiomyosarcoma) and hematological (1 non-Hodgkin's, 2 Hodgkin's lymphomas and 1 leukemia). Treatment is therefore modified, taking into consideration the treatment and prognosis of the primary disease.- - - - - - - - - - ranking = 0.0013912346077004keywords = leukemia (Clic here for more details about this article) |
6/11. Secondary leukemia after treatment with paclitaxel and carboplatin in a patient with recurrent ovarian cancer.The occurrence of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) has been reported after treatment with cytotoxic alkylating agent-based chemotherapy for solid tumors. We report a patient with metastatic ovarian carcinoma treated with carboplatin and paclitaxel, who developed secondary acute erythroid leukemia. The overall survival of patients with stage III and IV ovarian cancer has increased in the past decade. Monitoring of the long-term outcome of paclitaxel- and platinum-based regimens is warranted, particularly with regard to monitoring the development of secondary MDS and/or AML. The incidence and outcome of secondary leukemia in the setting of active ovarian carcinoma is reviewed.- - - - - - - - - - ranking = 0.0097386422539026keywords = leukemia (Clic here for more details about this article) |
7/11. Genealogy of cancer in a family.Three brothers had separate childhood cancers--osteogenic sarcoma, acute lymphoblastic leukemia, and bilateral malignant neurilemoma. Comprehensive family history showed a total of 16 cases of cancer among the descendants of the proband's great-great-great-grandmother, including a previously unsuspected cluster of similar neoplasms in an distant branch. The constellation of tumors in the family included bony and soft-tissue sarcomas, brain and neural tumors, leukemia, and breast carcinoma, occurring in a pattern suggesting the action of an incompletely penetrant autosomal dominant gene with pleiotropic effects. In some cases the genetic predisposition may have interacted with environmental determinants to produce particular tumors.- - - - - - - - - - ranking = 0.0027824692154008keywords = leukemia (Clic here for more details about this article) |
8/11. Uterine tumors in ataxia-telangiectasia.Roughly one-third of patients with ataxia-telangiectasia (AT) develop malignant tumors, usually of lymphoid origin. AT patients also exhibit progeric changes. We describe three patients, between the ages of 27 and 32 years, with uterine tumors: one with a frank leiomyosarcoma and chronic T-cell leukemia, one with a multilobulated leiomyoma of uncertain malignant potential, and one with an unremarkable leiomyoma. Thus, the spectrum of tumors in AT patients beyond adolescence includes nonlymphoid malignancies and precocious, benign leiomyomas.- - - - - - - - - - ranking = 0.0013912346077004keywords = leukemia (Clic here for more details about this article) |
9/11. radiation-induced leiomyosarcoma of the great vessels presenting as superior vena cava syndrome.A patient with a pleomorphic intravascular leiomyosarcoma of the great vessels of the neck and mediastinum presented clinically with a superior vena cava syndrome. A latent period of 29 years elapsed between receiving orthovoltage radiation to the neck and right side of chest to treat recurrent ganglioneuroblastoma, and the appearance of a leiomyosarcoma and subsequent recurrences. The patient underwent partial resection of the tumor, received adjunct chemotherapy, and was shown to be free of disease by clinical tests and by magnetic resonance imaging (MRI) 17 months after completion of chemotherapy. The criteria for the diagnosis of radiation-induced sarcomas are reviewed in relation to the present case. The critical role of magnetic resonance imaging in both the diagnosis and continued follow-up of the patient is described. This would appear to be the first reported case of radiation-induced intravascular leiomyosarcoma of the great vessels of the neck and mediastinum presenting as a superior vena cava syndrome.- - - - - - - - - - ranking = 2keywords = radiation-induced (Clic here for more details about this article) |
10/11. Adoptive chemoimmunotherapy using ex vivo activated memory T-cells and cyclophosphamide: tumor lysis syndrome of a metastatic soft tissue sarcoma.Adoptively transferred immune cells in combination with chemotherapeutic agents form the basis for adoptive chemoimmunotherapy (ACIT) of neoplastic disease. Autolymphocytes (ALT-cells) are ex vivo activated peripheral blood lymphocytes (PBL) from tumor-bearing hosts (TBH) that consist primarily of tumor-specific CD45RO (memory) T-cells. These ALT-cells combined with cimetidine (CIM) as autolymphocyte therapy (ALT), have previously been demonstrated to be a safe and active form of outpatient adoptive immunotherapy (AIT) in human TBH with metastatic renal cell cancer (RCC). We have previously described an effective ACIT protocol using ALT and cyclophosphamide (CY) for patients with relapsed and refractory non-RCC solid tumors. We now report a case of a patient with a metastatic gastric leiomyosarcoma to the liver, who developed a clinical picture consistent with a tumor-lysis syndrome (TLS), following salvage therapy for his tumor with ACIT using ALT and CY. TLS is a well-known complication resulting from the treatment of rapidly proliferating hematopoietic tumors such as Burkitt's lymphoma and acute lymphocytic leukemia. TLS has also been rarely described in chronic lymphocytic leukemia, as well as certain solid tumors such as breast cancer, small cell lung cancer, and medulloblastoma. However, there have been no previous reports of TLS occurring either secondary to immunotherapy or in sarcomas. The nature of these unusual findings is discussed.- - - - - - - - - - ranking = 0.0027824692154008keywords = leukemia (Clic here for more details about this article) |
