ABSTRACT

ABSTRACT To establish the profile of patients who developed antiangiogenic agent-related osteonecrosis of the jaws, and identify the treatments currently used in dental management. We searched the PubMed®/Medline® and Scopus databases using the words "osteonecrosis AND antiangiogenic therapy", with the following inclusion criteria: articles published in English, case reports, available online, and for an unlimited period. Of the 209 articles retrieved, 18 were selected, for a total of 19 case reports, since one article included two cases that met the inclusion criteria for this study. Medication-related osteonecrosis of the jaws is characterized by exposure of necrotic bone in the oral cavity that does not heal over a period of 8 weeks in patients with no previous history of radiation therapy. Antiangiogenic drugs are indicated in the treatment of certain tumors, since they stop the formation of new blood vessels, controlling tumor growth and the chance of metastasis. Dental prevention is essential in patients who will be put on antiangiogenic agents, to minimize the risk for osteonecrosis.


RESUMO Traçar o perfil dos pacientes que desenvolveram osteonecrose dos maxilares associada a agentes antiangiogênicos e identificar os tratamentos realizados atualmente no manejo odontológico. Foi realizada busca nas bases de dados PubMed®/Medline® e Scopus por meio dos descritores "osteonecrosis AND antiangiogenic therapy", sendo utilizados os critérios de inclusão: artigos publicados em inglês, relato de caso, disponíveis on-line e por período ilimitado. Após análise dos 209 artigos encontrados, foram selecionados 18 artigos para este estudo, resultando em 19 relatos de caso, visto que um dos artigos apresentou dois casos que se enquadravam nos critérios de inclusão. A osteonecrose dos maxilares associada a medicamentos é caracterizada pela exposição de osso necrótico na cavidade oral que não cicatriza em um período de 8 semanas em pacientes que não foram submetidos à radioterapia. Os medicamentos antiangiogênicos são indicados no tratamento de alguns tumores, pois impedem o crescimento de novos vasos sanguíneos, controlando o crescimento do tumor e a chance de metastização. Torna-se imprescindível a realização de prevenção odontológica do paciente a ser submetido a uso de antiangiogênicos visando a minimizar as chances de desenvolvimento da osteonecrose.

ABSTRACT

ABSTRACT Primary osseous angiosarcoma is a rare entity with variable biological behavior and poor prognosis. Little is known about the oncologic treatment and its etiology is still unknown. This study presents a case of lytic lesion in the right femur with dissemination to other bones, such as the vertebral column and skull, and to the lungs and central nervous system. Orthopedic surgery was performed in order to improve quality of life. Surgical specimen confirmed the diagnosis of high-grade malignant osseous angiosarcoma. Despite oncologic and orthopedic treatment, the patient had rapid and aggressive progression with a poor outcome.


RESUMO O angiossarcoma ósseo (AO) é uma patologia rara de comportamento biológico variável e com prognóstico reservado. Pouco se conhece sobre o seu tratamento oncológico e sua etiologia ainda é desconhecida. Os autores apresentam um caso de lesão lítica em fêmur proximal que se disseminou para outros ossos (tais como coluna e crânio), pulmão e sistema nervoso central. Foi instituído tratamento ortopédico, com vistas a uma melhoria da qualidade de vida e ao conforto do paciente. O diagnóstico de AO maligno de alto grau foi confirmado pelo espécime cirúrgico. Apesar disso e do tratamento oncológico feito, o paciente apresentou uma evolução rápida e agressiva com desfecho desfavorável.

ABSTRACT

Objectives To evaluate the clinical efficacy and safety of hypofractionated radiotherapy for cancer patients with hepatic metastases. Methods From May 2007 to November 2016,45 patients ( male:female=20:25) with inoperable hepatic metastases were enrolled in this investigation. The median age was 58 years old ( range:25-83).The median Karnofsky performance score ( KPS) was 80.Primary colorectal cancer was detected in 14 patients,primary breast cancer in 9 and primary lung cancer in 6 cases. Twenty-one patients had extrahepatic metastases. A total of 52 lesions were treated. Thirty-four cases received radiotherapy for one single lesion. The fractional dose was 45 Gy/3 fractions and 60 Gy/10-15 fractions. The median gross tumor volume (GTV) was 10. 1 cm3(0. 3-175. 2 cm3) and 29. 8 cm3(5. 0-209. 6 cm3) for planning target volume ( PTV).Seventeen CT images were fused with MRI and IMRT was adopted in 43 cases. The median dose of PTV was 60 Gy (40-60 Gy) and 90 Gy (60-132 Gy) for bioequivalent dose (BED). Results The median follow-up time was 23. 5 months and the median survival time was 26. 0 months (95%CI:21.4-30.6 months).The 1-year local control (LC),disease-free survival (DFS) and overall survival ( OS ) were 94%, 27% and 91%, respectively. Six cases died of liver metastases and abnormal liver function. Conclusion Hypofractionated radiotherapy is an efficacious and safe local treatment for inoperable hepatic metastases.

ABSTRACT

Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2%) were males and 49 (45.8%) were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years. Of the 107 lymph node biopsies, 34 cases (31.8%) were reactive lymphadenitis, 41 cases (38.3%) were tuberculosis, 2 cases (1.9%) were non-caseous granuloma, 6 cases (5.6%) were Hodgkin lymphoma, 8 cases (7.5%) were non-Hodgkin lymphoma, 12 cases (11.2%) were metastatic neoplasm and 4 cases (3.7%) were other specific lesions. Conclusion: The commonest cause of cervical lymphadenopathy was tuberculosis, followed by reactive lymphadenitis, lymphoma and metastatic neoplasm.

ABSTRACT

Background: Lymphadenopathy is a common manifestation of a large variety of disorders, both benign and malignant. It is essential to define the pattern of disorders presenting primarily as lymph node enlargement in a particular environment. Histopathological examination of the lymph node biopsies is a gold standard test in the distinction between reactive and malignant lymphoid proliferations as well as for detailed subtyping of lymphomas. We designed this study in our population for histopathological evaluation of lymph nodes that might be helpful for clinical management of these lesions. Objective: Histopathological evaluation of lymphadenopathy from excised specimen, in relation to age and sex of the patients, and distribution of the lymph nodes. Materials and Methods: It was a retrospective cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. Lymph node biopsies of all patients of both sexes and all age groups were included. Metastatic lymph nodes associated with evidence of primaries elsewhere in the body were excluded from the study. Total 191 lymph node biopsies were selected for histopathological evaluation. Among these 90 (47.12%) were from males and 101 (52.88%) were from females with male to female ratio being 1:2.1. The age of the patients ranged from 2 to 85 years with a mean age of 35.73 ± 18 years. Results: Cervical lymph nodes were the most common (56%) biopsied group. Of the 191 cases 59 cases (30.89%) were reactive lymphadenitis, 64 cases (33.5%) were tuberculosis, 2 cases (1.05%) were non-caseous granuloma, 11 cases (5.76%) were Hodgkin lymphoma, 22 cases (11.52%) were non-Hodgkin lymphoma, 24 cases (12.57%) were metastatic neoplasm and 9 cases (4.7%) were other lesions. Conclusion: Tuberculosis was the most common cause of lymphadenopathy, followed by reactive lymphadenitis and the cervical group of lymph nodes was most frequently affected.

ABSTRACT

Extrahepatic metastasis of hepatocellular carcinoma (HCC) can be found in various organs, but metastasis to the female genital tract is extremely rare. A 48-year-old woman who had undergone curative left lobectomy for small HCC 4 years earlier was admitted because of sequential alpha-fetoprotein elevation. Upon abdominal MRI and hepatic angiography, no evidence of HCC recurrence was found in the remnant liver. However, a positron emission tomography CT scan showed a hypermetabolic lesion in the uterine fundus, which was revealed as metastatic HCC after total hysterectomy. This is, to our knowledge, the first documented case of metastatic uterine tumor that originated from HCC without intrahepatic recurrence.

ABSTRACT

Objective To analyze the significance of urinary type Ⅰ collagen cross-linked N-telopeptides (uNTX) for the prognosis and response to therapy of bone metastatic neoplasms.Methods The subjects were divided into 3 groups: A,B and C.The levels of uNTX were measured by enzymatic immunoassay kit,and the activity of serum alkaline phosphatases(AKP) and calcium concentration were measured simultanuously.Results uNTX levels positively correlated with bone metastatic neoplasms,and were markedly high in the patients with extensive bone collagen breakdown.Conclusions uNTX is more sensitive than the activity of serum AKP and plasma calcium concentration for bone metastasis of neoplasms,so it is significant in differentiating and monitoring bone metastatic neoplasms.The measurement of uNTX is an early objective methods for evaluation of prognostic response to therapy of bone metastatic neoplasms.
