1/52. Malignant haemangioendothelioma of bone in a HbSC disease patient--a case report.We report here a 35-year-old man with sickle cell disease (SCD), who presented in 1989 with pain in the (R) hip of 7 years duration and swelling of the (R) calf of 3 months duration. Clinical examination revealed a hard tender mass in the (R) calf. histology of the (R) calf mass revealed haemangioendothelioma (HE), similar to the histology of the (R) iliac bone mass obtained in another institution previously. He was treated with external radiotherapy with the 1.25 megavoltage beam to antero-posterior fields of the (R) hemipelvis and (R) calf, with good response. Chemotherapy was subsequently administered using 6 cycles of VAC regime. The patient remained in remission for 12 months. In 1991 he had lymphoedema of (R) lower limb and received further radiotherapy and chemotherapy after an isotope bone scan had revealed disease activity in the (R) hemipelvis, (R) femur and (L) upper tibia. He responded again with complete regression of the lymphoedema and remained well until April 1993 when the lymphoedema recurred. He died while being evaluated for further treatment. Although there is no evidence to suggest that SCD confers any protection from development of neoplasms, the co-existence of SCD with a neoplasm is not common. We consider the occurrence of HE of bone, a rare malignancy, in a HbSC patient worthy of reporting.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
2/52. adult T-cell leukemia/lymphoma in which the pathohistological diagnosis was identical to that of Ki-1 positive anaplastic large cell lymphoma.A 65-year-old man developed severe lumbago and a loss of appetite two months before presentation. A computerized tomograph at admission revealed soft tissue masses destroying the Th12, L4 and L5 vertebral bones. We diagnosed the lesions to be metastatic bone tumors, but the primary focus could not be determined. Just after the irradiation treatment, abnormal lymphocytes were detected in the peripheral blood cells. Under the suspicion of adult T-cell leukemia/ lymphoma (ATL), we thus performed a lymph node biopsy. The specimens were histologically composed of Ki-1 positive anaplastic large cell lymphoma (ALCL). The lymphoma cells demonstrated a biclonal integration of HTLV-1 proviral dna. After 6 cycles of chemotherapy, the patient has demonstrated a partial and favorable remission from ATL.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
3/52. Third malignancy after treatment of Hodgkin's disease.We present a case of 36-year-old man who was treated for IIB supradiaphragmatic lymphocyte-predominant Hodgkin's disease in 1972 (at the age of 11). The patient remained relapse-free after combined radiotherapy (irradiation of the right supraclavicular field) and chemotherapy (six MOPP cycles) and a 3-year supporting chemotherapy (Velbe). In 1993 he underwent spinal cord surgery for a right-sided "hour glass" schwannoma at C4-5 level. In 1996 a large formation histologically verified as "chondrosarcoma" occurred in the right supraclavicular and axillary regions. The pathogenesis of the second and third malignancies may be attributed to the histologic pattern of HD with long-term survival and increased cumulative risk, non-alternating MOPP courses and continued supporting therapy and radiotherapy given to the involved fields.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
4/52. Langerhans cell histiocytosis after therapy for a malignant germ cell tumor of the central nervous system.Langerhans cell histiocytosis (LCH) is a clonal neoplastic disorder that results in a spectrum of clinical manifestations. Known to be associated with a variety of malignant diseases, LCH may precede, coincide with, or develop after the diagnosis of cancer. A child with a malignant germ cell tumor of the brain who subsequently experienced LCH is reported. The 8-year-old boy was treated for an immature teratoma of the posterior fossa with gross total resection and craniospinal irradiation preceding bleomycin, etoposide, and vinblastine chemotherapy for four cycles. Seven months after completion of therapy, he experienced multifocal bone disease with LCH.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
5/52. Osteoid osteomas with chromosome alterations involving 22q.cytogenetic analysis was performed in two osteoid osteomas. In both, the modal chromosome number was 46. One of the cases presented a del(22)(q13.1) as the sole clonal chromosome alteration. The other had clonal monosomies of chromosomes 3, 6, 9, 17, 19, and 21, as well as a del(22)(q13.1) was detected as a non-clonal chromosome alteration. There is only one osteoid osteoma reported so far showing clonal karyotypic alterations. The cytogenetic behavior of osteoid osteomas described here was different from that of the osteoid osteoma of the literature. Numerical alterations of chromosomes 3, 6, 9, 17, 19, 21 and 22 have been described in several neoplasias including bone tumors. The breakpoint of chromosome 22 involves a region where important genes for the regulation of the cell cycle have been mapped.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
6/52. Metastatic breast cancer in pregnancy: first case of chemotherapy with docetaxel.The focus of this paper is a case study of a woman in the first trimester of pregnancy who presented with metastatic breast cancer. The bony spread of the metastases was rapid and it was necessary to treat the patient as soon as possible after the period of organogenesis (days 18-60 of human gestation). This stage is the phase of greatest sensitivity of teratogens and the malformations are observed most often. Yet, the choice of third-line chemotherapy was difficult because of anthracycline-resistant metastatic breast cancer. The world literature reported cytotoxic combinated regimens as the standard of care for the management of the metastases. The development of new antitumoral strategies with less toxicity and their encouraging results led us to the approval of docetaxel for the treatment of the patient even though it had never been tested in pregnancy. Docetaxel is a potent inhibitor of microtubule depolymerization and has a unique ability to alter certain classes of microtubules. The monochemotherapy was administered once every 3 weeks for a total of three cycles until 30 weeks of gestation. During the 32nd week of pregnancy the patient delivered a female infant whose birthweight and apgar score were normal. The infant did not have any anomalies. The woman finished her treatment in puerperium and she received three cycles of docetaxel. The patient has been receiving vinorelbine (one cycle every 2 weeks) for 2 years; her last follow-up was good and showed that the progression of the metastases had stopped. The daughter's psychophysical development was normal.- - - - - - - - - - ranking = 3keywords = cycle (Clic here for more details about this article) |
7/52. A case report of recurrent epithelial ovarian cancer metastatic to the sternum, diaphragm, costae, and bowel managed by aggressive secondary cytoreductive surgery without postoperative chemotherapy.BACKGROUND: Ovarian epithelial cancer typically presents in advanced stage and has been traditionally managed by a combination of cytoreductive surgery followed by adjuvant systematic chemotherapy. The management of recurrent ovarian cancer has been individualized: surgical resection of intraabdominal and/or pelvic disease has been performed when technically feasible and usually followed with chemotherapy. CASE: This case describes aggressive surgical management of recurrent ovarian cancer metastatic to the lower ribs, sternum, and diaphragm. A clear cell, Stage IIIA ovarian cancer was successfully resected in a 73-year-old female. The patient had total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy followed by six cycles of adjuvant chemotherapy, consisting of cyclophospamide and carboplatinum. A period of 8 years elapsed before recurrent disease was detected; there were two separate metastatic sites. A secondary cytoreductive surgery without further chemotherapy has been the mainstay of treatment. A combination of exploratory laparotomy and en bloc resection revealed the metastatic deposits, a 5-cm mass involving the diaphragm, the lower aspect of the manubrium sternum, and four right lower ribs. The second deposit was identified in the left paracolic gutter invading the sigmoid colon. CONCLUSION: At 47 months of follow-up, the patient is alive and without any evidence of measurable disease by exam and confirmed by CT scans of chest, abdomen, and pelvis. To our knowledge, this is one of the few reported cases managed successfully by surgical approach and is recommended in selected patients with metastatic ovarian cancer.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
8/52. Successful treatment of extracranially metastasized pineal gland germinoma with high-dose methotrexate.germinoma of the pineal gland is a rare disease usually confined to the brain which responds well to radiotherapy. Spinal seeding occurs in approximately 4% of cases and distant metastases are extremely rare. We report on a 27-year-old female with an intracranially metastasized pineal gland germinoma, meningeal carcinomatosis and distant bone metastases. Treatment was initiated with intrathecal methotrexate (MTX) and continued with high-dose intravenous MTX. The therapy was very well tolerated apart from reversible hepatic toxicity requiring a dose reduction. The patient was in complete remission after three courses followed by two consolidation cycles; the patient has now been in continuous complete remission for more than 22 months. This is the first report to show that MTX is a potent drug in treating pineal gland germinoma. Long-term side effects of radiotherapy such as reduced mental function or hypopituitarism can probably be avoided. Single-agent high-dose MTX may provide high efficacy with limited adverse effects, especially at a more advanced tumor stage with spinal seeding and extracranial disease.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
9/52. osteosarcoma after bone marrow transplantation for acute lymphoblastic leukemia.A male patient initially diagnosed with acute lymphoblastic leukemia at age 9 years received chemotherapy (total body irradiation, 12 Gy) followed by allogeneic bone marrow transplantation. Since then, he had been in complete remission. Three years after the bone marrow transplantation, he complained of increasing pain in the right knee. Radiological and histological examinations led to a diagnosis of conventional osteosarcoma. We performed intensive chemotherapy and wide local excision of the osteosarcoma. Intensive chemotherapy was accomplished as planned, although recovery from myelosuppression was delayed during some cycles. polymerase chain reaction-single-strand conformation polymorphism analysis revealed a p53 gene mutation in exon 7 in the tumor cells, but not in skin or blood cells. This is an extremely rare case of osteosarcoma after bone marrow transplantation.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
10/52. Active chemotherapy for bone metastasis in sarcomatoid renal cell carcinoma.Sarcomatoid renal cell carcinoma (SRCC) is associated with an aggressive course, high incidence of bone metastasis, and an extremely poor prognosis. There are a few case reports concerning the effectiveness of chemotherapy on metastasis in SRCC. To our knowledge, however, there are no reports describing its effectiveness on bone metastasis. We report a 22-year-old woman with an 8-cm x 7-cm left renal mass. Left nephrectomy was done. The pathological diagnosis was SRCC, INF-beta, pT3aN2. Although, she received continuous infusion of interferon alpha-2a (INFalpha-2a) and interleukin-2 (IL-2) as adjuvant therapy, liver metastasis appeared 2 months later. Resection of the liver metastasis was done. After resection of the metastasis, multiple bone metastases appeared, in both humeri, the left chest wall, the left fourth rib, and the left iliac bone. The patient was treated with gemcitabine, 1000 mg/m(2) (days 1, 8), docetaxel 80 mg/m(2) (day 1), and carboplatin 300 mg/m(2) (day 1). A computed tomography (CT) scan after the first cycle revealed that the multiple osteolytic bone tumors had significantly decreased in size. Her ability of daily life (ADL) improved and this continued for almost 2 months. A second course of chemotherapy, with gemcitabine and IL-2 was given, but it was ineffective, and the patient died approximately 16 months after the initial diagnosis of SRCC. Combination chemotherapy with gemcitabine, docetaxel, and carboplatin was effective for the bone metastasis of SRCC.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
