Leptomeningeal metastasis, which results from metastasis of tumors to the arachnoid and pia mater, can lead to the dissemination of tumor cells throughout the subarachnoid space via the cerebral spinal fluid, and frequently with a poor prognosis. The primary tumor in adults is most often breast cancer, lung cancer, or melanoma. Although leptomeningeal metastasis due to cholangiocarcinoma has been reported, to the best of our knowledge there is no cytologically confirmed report of leptomeningeal metastasis from hepatocellular carcinoma. We herein report a case of leptomeningeal metastasis from hepatocellular carcinoma in a 53-year-old woman with concomitant systemic metastases to the lung, bone, brain, kidney, adrenal gland, subcutaneous tissues, and abdominal pelvis. The neurological symptoms of the patient were relieved after treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy. To our knowledge this is the first report of leptomeningeal metastasis from hepatocellular carcinoma confirmed by cytology. Treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy was effective

Full Text Available Introduction. Brain metastases from epithelial ovarian cancer (EOC are rare events. We present a rare case of single ovarian cancer metastasis to the brain treated with gamma-knife radiosurgery (GKRS. Case Outline. A 65-year-old woman with advanced EOC presented with severe neurologic symptoms. A single brain metastasis of 3.2 cm with surrounding edema in the left parietal lobe was detected by brain magnetic resonance imaging (MRI scan during the work-up. The decision to perform GKRS was due to a surgical inaccessibility of intracranial lesion. Twelve weeks after the procedure, the MRI scan showed reduction in the diameter of brain metastasis and surrounding edema and the patient returned to good mental and motor performance. The patient survived for 22 months following treatment and died from a progressive intra-abdominal disease. Prognosis of ovarian cancer patients with brain metastases is generally poor regardless of treatment. Conclusion. Our case shows that GKRS as primary treatment modality for the control of ovarian cancer metastases to the brain was effective and can be considered as a treatment of choice if international selection criteria are followed.

During childhood, neuroblastoma is a relatively common malignant neoplasm which commonly metastasizes to other organs. Metastasis to the central nervous system from an extracranial neuroblastoma is rare, however, and brain parenchymal metastasis is very rare. We describe a case of brain parenchymal metastasis from primary abdominal neuroblastoma, and review the literature

Brain metastasis from breast cancer generally represents a catastrophic event yet demonstrates substantial biological heterogeneity. There have been limited studies solely focusing on the prognosis of patients with such metastasis. In this study, we carried out a comprehensive analysis in 108 consecutive patients with breast cancer brain metastases between 1997 and 2012 to further define clinicopathological factors associated with early onset of brain metastasis and survival outcomes after development of them. We found that lobular carcinoma, higher clinical stages at diagnosis, and lack of coexisting bone metastasis were significantly associated with a worse brain relapse-free survival when compared with brain-only metastasis. High histologic grade, triple-negative breast cancer, and absence of visceral involvement were unfavorable prognostic factors after brain metastasis. Furthermore, high histologic grade, advanced tumor stages, and lack of coexisting bone involvement indicated a worse overall survival. Thus, the previously established prognostic factors in early stage or advanced breast cancers may not entirely apply to patients with brain metastases. Furthermore, the prognostic significance of the clinicopathological factors differed before and after a patient develops brain metastasis. This knowledge might help in establishing an algorithm to further stratify patients with breast cancer into prognostically significant categories for optimal prevention, screening, and treatment of their brain metastasis.

Brain tuberculosis is still prevalent in many developing countries, especially Asian countries. Tuberculomas should always be considered in the differential diagnosis of enhancing intra-axial lesions of the brain. Brain tuberculomas can present in many different clinical and radiological patterns clinically like headache, fits, cranial nerve palsies and very rarely as brain tuberculomas. We describe the case of a 48 years old male patient presenting with persistent headache and fits, referred for workup of brain metastasis or primary brain neoplasm. On further imaging, it turned out to be multiple tuberculomas of brain which resolved on anti-tuberculous treatment along with symptoms relief. (author)

Komaki, R.; Cox, J.D.; Stark, R.

1983-01-01

From January 1970 through December 1981, 469 patients with histologically or cytologically proven adenocarcinoma (AC) (349) and large cell carcinoma (LC) (120) of the lung were seen at the Department of Radiation Oncology, Medical College of Wisconsin Affiliated Hospitals. One quarter (126/469) of these patients had brain metastasis: 48 patients presented with brain metastasis and 78 patients subsequently developed brain metastasis. Brain was the dominant site of metastasis in 82 patients who received only cranial + thoracic irradiation; 37 patients (17 simultaneous, 20 metachronous) also required irradiation of other sites of metastasis. All 17 patients with LC, and 47/61 (77%) with AC who developed metachronous brain metastasis did so within one year. The cumulative probability of brain metastasis increased with survival to the levels predicted by autopsy studies. Therapeutic brain irradiation may result in long-term survival in patients with single organ brain metastasis. Since patients with AC and LC so frequently develop brain metastasis and the brain may be the only site of metastasis, prophylactic cranial irradiation may significantly reduce morbidity and mortality from these diseases

The incidence of brain metastasis from hepatocellular carcinoma (HCC) is expected to increase as a result of prolonged survival due to the recent advances in HCC treatment. However, there is no definite treatment strategy for brain metastasis from HCC mainly due to its rarity and dismal prognosis. To provide helpful recommendations in treatment of brain metastasis from HCC, the authors aimed to identify prognostic factors that influence survival rates with a review of the recently published data. Thirty-three cases of brain metastasis, whose incidence was 0.65%, were selected from a total of 5015 HCC patients and reviewed retrospectively in terms of clinical and radiological features. Median overall survival time after diagnosis of brain metastasis was 10.4 weeks (95% confidence interval [CI], 5.1-15.7 weeks) with 1-, 6- and 12-month survival rates, of 79%, 24% and 6%, respectively. Median survival of the patients treated with surgical resection or surgical resection followed by whole-brain radiation therapy (WBRT) (25.3 weeks; range, 15.8-34.8 weeks) was longer than that of the patients treated with gamma knife surgery (GKS), WBRT, or GKS followed by WBRT (10.4 weeks; range, 7.5-13.3 weeks) as well as that of patients treated with only steroids (1 week; range, 0.0-3.3 weeks) (p < 0.001). Child-Pugh’s classification A group had a longer median survival time than Child-Pugh’s classification B or C group (14.4 weeks vs 8.4 weeks, p = 0.038). RPA class I & II group had also a longer median survival time than RPA class III group did (13.4 weeks vs 2.4 weeks, p = 0.001). Surgical resection (hazard ratio [HR] 0.23, 95% CI 0.08-0.66, p = 0.006) and good liver function at the time of brain metastasis (HR 0.25, 95% CI 0.09-0.69, p = 0.007) were found to be the powerful prognostic factors for favorable survival in the multivariate analysis. In addition, presence of intratumoral hemorrhage was a statistically significant prognostic factor for survival. Although HCC

Retrospective analysis of the influence of clinical and technical factors on local control and survival after radiosurgery for brain metastasis. From january 1994 to December 1996, 42 patients presenting with 71 metastases underwent radiosurgery for brain metastasis. The median age was 56 years and the median Karnofsky index 80. Primary sites included: lung (20 patients), kidney (seven), breast (five), colon (two), melanoma (three), osteosarcoma (one) and it was unknown for three patients. Seventeen patients had extracranial metastasis. Twenty-four patients were treated at recurrence which occurred after whole brain irradiation (12 patients), surgical excision (four) or after both treatments (eight). Thirty-six sessions of radiosurgery have been realized for one metastasis and 13 for two, three or four lesions. The median metastasis diameter was 21 mm and the median volume 1.7 cm 3 . The median peripheral dose to the lesion was 14 Gy, and the median dose at the isocenter 20 Gy. Sixty-five metastasis were evaluable for response analysis. The overall local control rate was 82% and the 1-year actuarial rate was 72%. In univariate analysis, theoretical radioresistance (P = 0.001), diameter less than 3 cm (P = 0.039) and initial treatment with radiosurgery (P 0.041) were significantly associated with increased local control. Only the first two factors remained significant in multivariate analysis. No prognostic factor of overall survival was identified. The median survival was 12 months. Six patients had a symptomatic oedema (RTOG grade 2), only one of which requiring a surgical excision. In conclusion, 14 Gy delivered at the periphery of metastasis seems to be a sufficient dose to control most brain metastases, with a minimal toxicity. Better results were obtained for lesions initially treated with radiosurgery, theoretically radioresistant and with a diameter less than 3 cm. (authors)

Full Text Available Gallbladder cancer is a common malignancy in Northern India, and it accounts for 2-4% of all malignant gastrointestinal tumors. It is an aggressive tumor with early dissemination to liver and lymph nodes and associated with poor prognosis. Systemic metastases from gall bladder carcinoma (Ca frequently occur; however, metastatic involvement of the central nervous system is rare and late manifestation and remains an ominous sign. Initial presentation of gall bladder Ca with brain metastasis is rare. We report a case of 65-year-old women who initially presented with a solitary brain metastasis from an adenocarcinoma of the gallbladder, which was diagnosed incidentally when the patient presented with headache, vomiting, and right temporal region swelling. Palliative chemotherapy and cranial radiotherapy were prescribed. She is symptom-free from 3 months after the completion of the treatment.

Full text: Introduction: Because brain metastasis from well differentiated thyroid carcinoma is rare, management of patients presenting with this condition lacks consensus. A recent review of the literature found 17 reports of 75 cases from 1966-2001 in which 28 metastasis were from the brain, 5 from the spinal cord, 2 to both brain and spinal cord, We report our 5 cases with a focus on the last patient. Clinical presentation: A 66-year-old female treated by us for the past 10 years for papillary carcinoma of the thyroid with metastasis to bone. She presented in July 2003 with sudden onset of seizure. A non contrast CT scan demonstrated a solitary lesion in the right anterior high parietal region with a possible second lesion. Intervention: She underwent right frontal craniotomy to expose superior sagittal sinus. An inter-hemispheric approach demonstrated a tumor in the supra-meningeal gyrus that was attached to the calloso-meningeal artery. The histopathology of the surgical specimen confirmed a follicular variant of papillary carcinoma of the thyroid. She then received 11100 MBq 1-131 irradiation, Conclusion: the best therapeutic option for brain metastasis seems to be surgical resection with or without post operative Irradiation with 1-131. Central nervous system metastasis should always be investigated and treated aggressively to improve patients' long term outcome. (author)

The brain microenvironment imposes a particularly intense selective pressure on metastasis-initiating cells, but successful metastases bypass this control through mechanisms that are poorly understood. Reactive astrocytes are key components of this microenvironment that confine brain metastasis without infiltrating the lesion. Here, we describe that brain metastatic cells induce and maintain the co-option of a pro-metastatic program driven by signal transducer and activator of transcription 3 (STAT3) in a subpopulation of reactive astrocytes surrounding metastatic lesions. These reactive astrocytes benefit metastatic cells by their modulatory effect on the innate and acquired immune system. In patients, active STAT3 in reactive astrocytes correlates with reduced survival from diagnosis of intracranial metastases. Blocking STAT3 signaling in reactive astrocytes reduces experimental brain metastasis from different primary tumor sources, even at advanced stages of colonization. We also show that a safe and orally bioavailable treatment that inhibits STAT3 exhibits significant antitumor effects in patients with advanced systemic disease that included brain metastasis. Responses to this therapy were notable in the central nervous system, where several complete responses were achieved. Given that brain metastasis causes substantial morbidity and mortality, our results identify a novel treatment for increasing survival in patients with secondary brain tumors.

A 33-year-old woman had been operated on for a tumor of the thyroid gland in December of 1976, and was admitted to Saku Central Hospital in April of 1983 because of pulmonary and ovarian metastases. She underwent surgical removal of the metastatic ovarian tumor and chemotherapy, but developed headaches in June of 1983. Computed tomography (CT) scan revealed a well-defined, homogeneously enhanced mass in the right occipital region. Angiography showed a homogeneous, well-defined tumor stain supplied by the right posterior cerebral artery, the posterior branch of the middle meningeal artery, and the meningeal branch of the occipital artery. The tumor was removed in July of 1983. It was situated in the right occipital lobe and was supplied by numerous small meningeal vessels. Histologically, it was composed of small, oval-shaped cells, some with mitotic figures, and giant cells, occasionally forming a follicular structure. Three months later, the headaches reappeared, and a recurrence of brain metastasis was demonstrated by CT. In October of 1983, the second metastatic brain tumor and the dural bed were removed and local radiation therapy was administered. In this case, meningioma-like features were demonstrated by CT scan and angiography, and these findings may be characteristic of brain metastasis of follicular carcinoma of the thyroid gland.

Full Text Available Although extrahepatic metastases from hepatocellular carcinoma (HCC are present in only 5–15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma. After admission, cranial computed tomography revealed an intraparenchymal hemorrhage area with surrounding edema in the right frontal lobe. An angioresonance requested showed a large extra-axial mass lesion located in the right frontal region with well-defined contours and predominantly hypointense signal on T2 sequence. At first, the radiological findings suggested meningioma as the first diagnostic hypothesis. However, the patient underwent surgery. The tumor was completely removed, and the morphological and immunohistochemical findings were consistent with metastatic hepatocarcinoma associated with meningioma. In postoperative care, the patient did not recover from the left hemiparesis and manifested Broca’s aphasia. He had a survival time of 24 weeks, presenting acute liver failure as his cause of death. There is a lack of evidence supporting a specific management of patients with brain metastasis from HCC. Furthermore, there are no studies that evaluate different modalities of therapeutics in brain metastasis of HCC due to the rarity of this condition. Therefore, management must be individualized depending on probable prognostic factors in these patients.

2014-01-01

Full Text Available Background. Uterine leiomyosarcoma is a rare and aggressive gynecologic malignancy with an overall poor prognosis. Lungs, bones, and brain are common sites of metastases of uterine leiomyosarcoma. Metastases of uterine leiomyosarcoma to the small bowel are extremely rare, and only four case reports have been published to date. Case presentation. A 55-year-old Saudi woman diagnosed with a case of uterine leiomyosarcoma treated with total abdominal hysterectomy (TAH and bilateral salpingooophorectomy (BSO presented in emergency room after sixteen months with acute abdomen. Subsequent work-up showed a jejunal mass for which resection and end-to-end anastomosis were performed. Biopsy confirmed the diagnosis of small bowel metastasis from uterine leiomyosarcoma. Further staging work-up showed wide spread metastasis in lungs and brain. After palliative cranial irradiation, systemic chemotherapy based on single agent doxorubicin was started. Conclusion. Metastatic leiomyosarcoma of small bowel from uterine leiomyosarcoma is a rare entity and is sign of advanced disease. It should be differentiated from primary leiomyosarcoma of small bowel as both are treated with different systemic chemotherapeutic agents.

Purpose: Whole-brain radiation therapy (WBRT) is the standard of care after resection of a brain metastasis. However, concern regarding possible neurocognitive effects and the lack of survival benefit with this approach has led to the use of stereotactic radiosurgery (SRS) to the resection cavity in place of WBRT. We report our initial experience using an image-guided linear accelerator-based frameless stereotactic system and review the technical issues in applying this technique. Methods and Materials: We retrospectively reviewed the setup accuracy, treatment outcome, and patterns of failure of the first 18 consecutive cases treated at Brigham and Women’s Hospital. The target volume was the resection cavity without a margin excluding the surgical track. Results: The median number of brain metastases per patient was 1 (range, 1–3). The median planning target volume was 3.49 mL. The median prescribed dose was 18 Gy (range, 15–18 Gy) with normalization ranging from 68% to 85%. In all cases, 99% of the planning target volume was covered by the prescribed dose. The median conformity index was 1.6 (range, 1.41–1.92). The SRS was delivered with submillimeter accuracy. At a median follow-up of 12.7 months, local control was achieved in 16/18 cavities treated. True local recurrence occurred in 2 patients. No marginal failures occurred. Distant recurrence occurred in 6/17 patients. Median time to any failure was 7.4 months. No Grade 3 or higher toxicity was recorded. A long interval between initial cancer diagnosis and the development of brain metastasis was the only factor that trended toward a significant association with the absence of recurrence (local or distant) (log-rank p = 0.097). Conclusions: Frameless stereotactic irradiation of the resection cavity after surgery for a brain metastasis is a safe and accurate technique that offers durable local control and defers the use of WBRT in select patients. This technique should be tested in larger prospective

2016-01-01

Full Text Available Brain metastasis (BM has been universally recognized as a poor prognostic factor in non-small cell lung cancer (NSCLC. Epidermal growth factor receptor (EGFR tyrosine kinase inhibitors (TKIs have shown efficacy in treating BM with an EGFR mutation. This paper reports a case of BM patient with EGFR-mutated NSCLC. According to the findings, a complete remission (CR of the BM was achieved by icotinib treatment without conducting a radiotherapy, which was followed by a resection of the primary lung cancer lesion and lymph nodes. After one-year follow-up, the disease progressed to liver metastasis and liver lesion biopsy showed a T790M mutation. The patient responded well to the combination treatment of AZD9291 and icotinib after the failure of transcatheter arterial chemoembolization (TACE. This case report suggests that icotinib has a sustainable anticancer response to BM and the combination with icotinib and AZD9291 is effective for liver metastasis with T790M.

Simultaneous meningioma and brain metastasis from renal cell carcinoma – a rare presentation. Case report

Full Text Available ABSTRACT CONTEXT: Brain metastases are the most common tumors of the central nervous system. Because of their high frequency, they may be associated with rare situations. Among these are tumor-to-tumor metastasis and an even a rarer situation called simultaneous brain tumors, which are more related to primary tumors of the reproductive and endocrine systems. CASE REPORT: A 56-year-old male patient with a history of renal cell carcinoma (which had previously been resected presented with a ventricular lesion (suggestive of metastatic origin and simultaneous olfactory groove lesion (probably a meningioma. First, only the ventricular lesion was dealt with, but after a year, the meningothelial lesion increased and an occipital lesion appeared. Therefore, both of these were resected in a single operation. All the procedures were performed by the same neurosurgeon. The patient evolved without neurological deficits during the postoperative period. After these two interventions, the patient remained well and was referred for adjuvant treatment. CONCLUSIONS: This study provides the first description of an association between these two tumors. Brain metastases may be associated with several lesions, and rare presentations such as simultaneity with meningioma should alert neurosurgeons to provide the best oncological treatment.

The vascular basement membrane as "soil" in brain metastasis.

Directory of Open Access Journals (Sweden)

W Shawn Carbonell

2009-06-01

Full Text Available Brain-specific homing and direct interactions with the neural substance are prominent hypotheses for brain metastasis formation and a modern manifestation of Paget's "seed and soil" concept. However, there is little direct evidence for this "neurotropic" growth in vivo. In contrast, many experimental studies have anecdotally noted the propensity of metastatic cells to grow along the exterior of pre-existing vessels of the CNS, a process termed vascular cooption. These observations suggest the "soil" for malignant cells in the CNS may well be vascular, rather than neuronal. We used in vivo experimental models of brain metastasis and analysis of human clinical specimens to test this hypothesis. Indeed, over 95% of early micrometastases examined demonstrated vascular cooption with little evidence for isolated neurotropic growth. This vessel interaction was adhesive in nature implicating the vascular basement membrane (VBM as the active substrate for tumor cell growth in the brain. Accordingly, VBM promoted adhesion and invasion of malignant cells and was sufficient for tumor growth prior to any evidence of angiogenesis. Blockade or loss of the beta1 integrin subunit in tumor cells prevented adhesion to VBM and attenuated metastasis establishment and growth in vivo. Our data establishes a new understanding of CNS metastasis formation and identifies the neurovasculature as the critical partner for such growth. Further, we have elucidated the mechanism of vascular cooption for the first time. These findings may help inform the design of effective molecular therapies for patients with fatal CNS malignancies.

Polychlorinated biphenyls (PCBs) are environmental toxicants that cause vascular inflammation and facilitate the development of brain metastases. The crucial event in metastasis formation is adhesion of blood-borne tumor cells to the vascular endothelium, followed by their transcapillary migration. The aim of the present study was to examine the mechanisms of PCB118-induced brain metastasis formation at the blood-brain barrier level with the focus on tumor cell adhesion to the brain endotheli...

Introduction: The differentiated thyroid cancer is the most common endocrine neoplasia. The major manifestation belongs to the papillary variant (65-90%). The prognosis tends to be very favorable, with a mortality rate of 1.8 % and a disease-free rate up to 10 years of around 90-95 %. The distant metastasis in brain accounts for 0.1-5 %. There are no established protocols for the management of brain metastasis. Therapeutic options are: surgery, stereotactic radiotherapy / radiosurgery, and "1"3"1I. The successful management of this case is an option for brain metastasis from thyroid papillary carcinoma. Case report: A 77 year-old female begins with double vision (diplopia). She underwent twice a surgery for brain tumor with a histopathological report on thyroid papillary tissue. The endocrine evaluation determines euthyroid state except thyroglobulin (TG) 2300 ng/ml. Total thyroidectomy with classic thyroid papillary carcinoma. A diagnostic "1"3"1I scan after surgery shows for first time brain metastasis uptake. The patient receives 25 mCi of "1"3"1I as initial therapeutic dose, and subsequent therapeutic doses (50, 50, 75, 75, 50 mCi) in 2 years, in accordance with the evolution of magnetic resonance, clinic, endocrine lab, hematological analysis, and "1"3"1I scintigraphy, that shows the possible remission of the disease. The follow-up was carried out by means of a clinical control, thyroglobulin values, U.S., "1"3"1I scans, and magnetic resonance. The patient is at the present time over 11 years survival and 8 years disease-free. Discussion: Even though the distant metastasis is not very common in brain and is generally associated with aggressive variants of tumor, our case started with a metastatic brain tumor in an euthyroid patient with no thyroid pathology background and with low-risk post-thyroidectomy criterion. The "1"3"1I scan turned positive in brain metastasis when the patient was thyroidectomized. This detail must be considered important, since it

Full Text Available INTRODUCTION: The incidence of brain metastasis due to breast cancer is increasing, and prognosis is poor. Treatment is challenging because the blood-brain barrier (BBB limits efficacy of systemic therapies. In this work, we develop a clinically relevant whole brain radiotherapy (WBRT plan to investigate the impact of radiation on brain metastasis development and BBB permeability in a murine model. We hypothesize that radiotherapy will decrease tumor burden and increase tumor permeability, which could offer a mechanism to increase drug uptake in brain metastases. METHODS: Contrast-enhanced magnetic resonance imaging (MRI and high-resolution anatomical MRI were used to evaluate BBB integrity associated with brain metastases due to breast cancer in the MDA-MB-231-BR-HER2 model during their natural development. Novel image-guided microirradiation technology was employed to develop WBRT treatment plans and to investigate if this altered brain metastatic growth or permeability. Histology and immunohistochemistry were performed on whole brain slices corresponding with MRI to validate and further investigate radiological findings. RESULTS: Herein, we show successful implementation of microirradiation technology that can deliver WBRT to small animals. We further report that WBRT following diagnosis of brain metastasis can mitigate, but not eliminate, tumor growth in the MDA-MB-231-BR-HER2 model. Moreover, radiotherapy did not impact BBB permeability associated with metastases. CONCLUSIONS: Clinically relevant WBRT is not curative when delivered after MRI-detectable tumors have developed in this model. A dose of 20 Gy in 2 fractions was not sufficient to increase tumor permeability such that it could be used as a method to increase systemic drug uptake in brain metastasis.

Colorectal cancer (CRC) is a leading cause of death in the elderly and about 20% of these patients present metastasis at diagnosis, most often in the liver. Other common metastatic sites include: lung, bone and brain. Isolated splenic metastases are rare, and they are usually a sign of widespread disease. The authors report a case of the rare occurrence of synchronous isolated splenic metastasis, diagnosed by computed tomography in the preoperative staging of a patient with CRC.O câncer color...

MicroRNA and protein profiling of brain metastasis competent cell-derived exosomes.

Directory of Open Access Journals (Sweden)

Laura Camacho

Full Text Available Exosomes are small membrane vesicles released by most cell types including tumor cells. The intercellular exchange of proteins and genetic material via exosomes is a potentially effective approach for cell-to-cell communication and it may perform multiple functions aiding to tumor survival and metastasis. We investigated microRNA and protein profiles of brain metastatic (BM versus non-brain metastatic (non-BM cell-derived exosomes. We studied the cargo of exosomes isolated from brain-tropic 70W, MDA-MB-231BR, and circulating tumor cell brain metastasis-selected markers (CTC1BMSM variants, and compared them with parental non-BM MeWo, MDA-MB-231P and CTC1P cells, respectively. By performing microRNA PCR array we identified one up-regulated (miR-210 and two down-regulated miRNAs (miR-19a and miR-29c in BM versus non-BM exosomes. Second, we analyzed the proteomic content of cells and exosomes isolated from these six cell lines, and detected high expression of proteins implicated in cell communication, cell cycle, and in key cancer invasion and metastasis pathways. Third, we show that BM cell-derived exosomes can be internalized by non-BM cells and that they effectively transport their cargo into cells, resulting in increased cell adhesive and invasive potencies. These results provide a strong rationale for additional investigations of exosomal proteins and miRNAs towards more profound understandings of exosome roles in brain metastasis biogenesis, and for the discovery and application of non-invasive biomarkers for new therapies combating brain metastasis.

Patients with brain metastasis from melanoma have poor outcomes. Radiation is used both for prognostic and symptomatic value. We aimed to further clarify the role of stereotactic radiosurgery (SRS) and whole brain radiotherapy (WBRT) as well as the prognostic implication of various sites of extracranial disease. The records of 73 consecutive patients treated at the University of Rochester Medical Center for brain-metastatic melanoma from January 2004 to October 2013 were reviewed. The median overall survival (OS) was 3.0 months. Patients treated with WBRT alone had decreased OS compared to those treated with SRS alone (HR = 0.38, p = 0.001) or WBRT and SRS (HR = 0.51, p = 0.039). The mean number of brain metastasis differed (p = 0.002) in patients in patients who received WBRT (4.0) compared to those who did not (2.0). Among patients with extracranial disease (n = 63), bone metastasis (HR = 1.86, p = 0.047, n = 15) was a negative prognostic factor; liver (HR = 1.59, p = 0.113, n = 17), lung (HR = 1.51, p = 0.23, n = 51) and adrenal metastasis (HR = 1.70, p = 0.15, n = 10) were not. In patients with concurrent brain and lung metastasis, those with disease limited to those two sites (OS = 8.7 mo, n = 13) had improved OS (HR = 0.44, p = 0.014) compared to those with additional disease (OS = 1.8 mo, n = 50). Based on this hypothesis-generating retrospective analysis, SRS may offer survival benefit compared to WBRT alone in patients with brain metastatic melanoma. Bone metastasis appears to confer a particularly poor prognosis. Those with disease confined to the lung and brain may represent a population with improved prognosis.

Stereotactic radiotherapy for brain metastasis

2012-01-01

Stereotactic radiosurgery is now well implanted in the radiotherapy treatment tools of brain metastasis. The dose can be delivered in one or multiple sessions. Results seem equivalent. CT scan and MRI imaging are required to delineate and calculate dosimetry. Doses are variable according to the size of the metastases, localization, pathology or equipment. Stabilization or reduction of tumour size is the rules after stereotactic treatment. Impact in terms of overall survival is more difficult to apprehend because of the general context of the disease. Many questions remain unresolved, such as the usefulness of whole brain irradiation, adaptation of the treatment schedule to tumour pathophysiology, role of stereotactic treatment after surgery of metastases, etc. (authors)

Objective: To investigate the pathway and MRI findings of meningeal metastasis original from lung cancer. Methods: 44 cases with cerebro-spinal meningeal metastasis original from lung cancer proven by clinical and pathology were retrospectively reviewed. All cases undergone plain MRI scan and Gd-DTPA enhanced MRI scan on brain and/or spine. Results: MRI plain scan indicated 28 cases with brain metastases, 3 cases with meningeal nodosity or irregularly patchy abnormal signal, 1 case with nodule in left cavernous sinus, 10 cases with abnormal signal in spine, 2 cases with abnormal signal in spinal dura mater. 34 cases with cerebro meningeal metastases were found in MRI enhancement scan. Among them, 11 cases displayed cerebral dura mater-arachnoid enhancement, 17 cases revealed cerebral pia mater-arachnoid enhancement and 6 cases with mixed typed enhancement. Osteoclasia in skull was found in 4 cases, spinal metastasis was revealed in 17 cases, and patchy abnormal enhancement in spinal dura mater was showed in 12 cases. Conclusion: Hematogenous metastasis is a main route of meningeal metastasis caused by lung cancer and enhanced MRI scan is of important diagnostic value. (authors)

Brain metastases among lung cancer patients can impair cognitive and functional ability, complicate care, and reduce survival. This study focuses on the economic burden of brain metastasis in lung cancer-direct healthcare costs to payers and indirect costs to patients, payers, and employers-in the US. Retrospective study using claims data from over 60 self-insured Fortune 500 companies across all US census regions (January 1999-March 2013). Adult, non-elderly lung cancer patients with brain metastasis were evaluated over two study periods: (1) pre-diagnosis (≤30 days prior to first observed lung cancer diagnosis to ≤30 days prior to first-observed brain metastasis diagnosis) and (2) post-diagnosis (≤30 days prior to first observed brain metastasis diagnosis to end of continuous eligibility or observation). Healthcare costs to payers and resource utilization, salary loss to patients, disability payouts for payers, and productivity loss to employers. A total of 132 patients were followed for a median of 8.4 and 6.6 months in the pre- and post-diagnosis periods, respectively. At diagnosis of brain metastasis, 21.2% of patients were on leave of absence and 6.1% on long-term disability leave. Substantial differences were observed in the pre- vs post-diagnosis periods. Specifically, patients incurred much greater healthcare utilization in the post-diagnosis period, resulting in $25,579 higher medical costs per-patient-per-6-months (PPP6M). During this period, patients missed significantly more work days, generating an incremental burden of $2853 PPP6M in salary loss for patients, $2557 PPP6M in disability payments for payers, and $4570 PPP6M in productivity loss for employers. Type of primary lung cancer and extent of brain metastasis could not be assessed in the data. The analysis was also limited to patients with comprehensive disability coverage. Development of brain metastasis among lung cancer patients is associated with a substantial economic burden to payers

Purpose: The effectiveness of stereotactic irradiation (STI) alone without whole-brain irradiation (WBI) for a single metastatic brain tumor was analyzed retrospectively. Methods and Materials: Forty-four patients with this condition were treated using radiosurgery (RS) alone or fractionated stereotactic radiotherapy (FSR) without WBI. Results: The initial response rate was 92% and the overall local control rate was 84% (37 of 44 patients). A total of 39% (18 of 44) of patients experienced intracranial relapse outside the initial target area. Forty-eight percent (21 of 44) of patients required salvage treatment for intracranial relapse. All 7 patients who received WBI as salvage treatment required no further salvage treatment, but 5 of the 14 patients who received salvage STI without WBI required three to four treatments for brain metastasis. Late radiation damage was not seen with initial treatment but was observed with retreatment. The overall median survival time was 261 days, with a standard error of 64 days. Actuarial survival at 12 and 24 months was 34% and 9%, respectively. The actuarial survival rate was significantly affected by the existence of active extracranial disease (p = 0.041). Conclusion: The high response rate and short treatment period of STI alone are advantageous in the treatment of single brain metastasis in patients with active extracranial disease with WBI reserved for relapse. Because of the low complication rate, STI alone may be also useful in patients with good prognosis, without extracranial disease

Full Text Available Abstract Background The prognosis for patients with breast tumor metastases to brain is extremely poor. Identification of prognostic molecular markers of the metastatic process is critical for designing therapeutic modalities for reducing the occurrence of metastasis. Although ubiquitously present in most human organs, large-conductance calcium- and voltage-activated potassium channel (BKCa channels are significantly upregulated in breast cancer cells. In this study we investigated the role of KCNMA1 gene that encodes for the pore-forming α-subunit of BKCa channels in breast cancer metastasis and invasion. Methods We performed Global exon array to study the expression of KCNMA1 in metastatic breast cancer to brain, compared its expression in primary breast cancer and breast cancers metastatic to other organs, and validated the findings by RT-PCR. Immunohistochemistry was performed to study the expression and localization of BKCa channel protein in primary and metastatic breast cancer tissues and breast cancer cell lines. We performed matrigel invasion, transendothelial migration and membrane potential assays in established lines of normal breast cells (MCF-10A, non-metastatic breast cancer (MCF-7, non-brain metastatic breast cancer cells (MDA-MB-231, and brain-specific metastatic breast cancer cells (MDA-MB-361 to study whether BKCa channel inhibition attenuates breast tumor invasion and metastasis using KCNMA1 knockdown with siRNA and biochemical inhibition with Iberiotoxin (IBTX. Results The Global exon array and RT-PCR showed higher KCNMA1 expression in metastatic breast cancer in brain compared to metastatic breast cancers in other organs. Our results clearly show that metastatic breast cancer cells exhibit increased BKCa channel activity, leading to greater invasiveness and transendothelial migration, both of which could be attenuated by blocking KCNMA1.

This study was conducted to compare the effects of whole brain radiotherapy (WBRT) and stereotactic radiotherapy (SRS) in treatment of brain metastasis.A systematical retrieval in PubMed and Embase databases was performed for relative literatures on the effects of WBRT and SRS in treatment of brain metastasis. A Bayesian network meta-analysis was performed by using the ADDIS software. The effect sizes included odds ratio (OR) and 95% confidence interval (CI). A random effects model was used for the pooled analysis for all the outcome measures, including 1-year distant control rate, 1-year local control rate, 1-year survival rate, and complication. The consistency was tested by using node-splitting analysis and inconsistency standard deviation. The convergence was estimated according to the Brooks-Gelman-Rubin method.A total of 12 literatures were included in this meta-analysis. WBRT + SRS showed higher 1-year distant control rate than SRS. WBRT + SRS was better for the 1-year local control rate than WBRT. SRS and WBRT + SRS had higher 1-year survival rate than the WBRT. In addition, there was no difference in complication among the three therapies.Comprehensively, WBRT + SRS might be the choice of treatment for brain metastasis.

Full Text Available Malignant melanoma of the vagina, a very rare malignancy, has a notoriously aggressive behavior associated with a high risk of local recurrence and distant metastasis. At present, there are various treatment options for this disease but no standard guideline. We describe a case of a 54-year-old woman with a locally advanced melanoma of the vagina, who underwent radical surgery, biochemotherapy with interferon-α-2b, chemotherapy, radiotherapy, and repeat excision of local recurrent lesions and brain metastasis. In conclusion, malignant melanoma of the vagina has a high risk for local recurrence. Repeated local excision followed by biochemotherapy is a tolerable treatment.

Breast cancer brain metastasis is resistant to therapy and a particularly poor prognostic feature in patient survival. Altered metabolism is a common feature of cancer cells but little is known as to what metabolic changes benefit breast cancer brain metastases. We found that brain-metastatic breast cancer cells evolved the ability to survive and proliferate independent of glucose due to enhanced gluconeogenesis and oxidations of glutamine and branched chain amino acids, which together sustain the non-oxidative pentose pathway for purine synthesis. Silencing expression of fructose-1,6-bisphosphatases (FBPs) in brain metastatic cells reduced their viability and improved the survival of metastasis-bearing immunocompetent hosts. Clinically, we showed that brain metastases from human breast cancer patients expressed higher levels of FBP and glycogen than the corresponding primary tumors. Together, our findings identify a critical metabolic condition required to sustain brain metastasis, and suggest that targeting gluconeogenesis may help eradicate this deadly feature in advanced breast cancer patients.

Transitional cell carcinoma (TCC) of the female urethra is a rare urological malignancy, and intracranial metastasis of this cancer has not yet been reported in the literature. This review is intended to present a case of multiple intracranial metastasis in a female patient with a remote history of primary urethral TCC. A 49-year-old woman, presented with a prolapsed mass in urethral orifice that was diagnosed as primary urethral TCC with distant lung and multiple bone metastases. The patient subsequently underwent chemotherapy under various regimens. A year later, the patient developed headache and vomiting which as was found to be due to multiple intracranial metastasis. The patient underwent surgical resection of the largest lesion located on the cerebellum, and consecutively gamma knife radiosurgery was performed for other small-sized lesions. Pathological examination of the resected mass revealed a metastatic carcinoma from a known urethral TCC. Serial work-up of systemic metastasis revealed concomitant aggravation of lung, spleen, and liver metastasis. The patient died of lung complication 2 months after the diagnosis of brain metastasis. To the best of our knowledge, this is the first reported case of cerebral metastasis from primary urethral TCC, with pathological confirmation. As shown in intracranial metastasis of other urinary tract carcinoma, this case occurred in the setting of uncontrolled systemic disease and led to dismal prognosis in spite of aggressive interventional modalities

Questions about both the place and the role of surgery on brain metastasis from breast cancer are arising more and more frequently in practice due to the increase of brain metastasis in patients suffering from a form of cancer recognized as one of the most recurrent cancers in adults but also one of the most sensitive to general treatments of the systemic disease. With improvements in anaesthesia, in surgical instruments, and in global care, neurosurgery has taken advantage of new techniques such as pre- and even per-operative imagery and also neuronavigation. These techniques enable radical and effective surgical intervention with a high level of safety for the patient, making neurosurgery perfectly competitive with other therapeutic modalities, particularly on functional grounds. As for symptomatic treatments or other anti-metastasis treatments, most situations allow a reflection on the global therapeutic strategy which can be adapted to individual cases depending on the patient's general prognosis. In developing this global therapeutic strategy, surgical treatment is still as relevant as ever.

The prognosis of patients diagnosed with stage IV nonsmall cell lung cancer that have brain and brainstem metastasis is very poor, with less than a third surviving a year past their initial date of diagnosis. We present the rare case of a 57-year-old man who is a long-term survivor of brainstem and recurrent brain metastasis, after aggressive treatment. He is now five and a half years out from diagnosis and continues to live a highly functional life without evidence of disease. Four separate Gamma Knife stereotactic radiosurgeries in conjunction with two craniotomies were utilized since his initial diagnosis to treat recurrent brain metastasis while chemoradiation therapy and thoracic surgery were used to treat his primary disease in the right upper lung. In his situation, Gamma Knife radiosurgery proved to be a valuable, safe, and effective tool for the treatment of multiply recurrent brain metastases within critical normal structures. PMID:23056973

Long planning time in volumetric-modulated arc stereotactic radiotherapy (VMA-SRT) cases can limit its clinical efficiency and use. A vector model could retrieve previously successful radiotherapy cases that share various common anatomic features with the current case. The prsent study aimed to develop a vector model that could reduce planning time by applying the optimization parameters from those retrieved reference cases. Thirty-six VMA-SRT cases of brain metastasis (gender, male [n = 23], female [n = 13]; age range, 32 to 81 years old) were collected and used as a reference database. Another 10 VMA-SRT cases were planned with both conventional optimization and vector-model-supported optimization, following the oncologists' clinical dose prescriptions. Planning time and plan quality measures were compared using the 2-sided paired Wilcoxon signed rank test with a significance level of 0.05, with positive false discovery rate (pFDR) of less than 0.05. With vector-model-supported optimization, there was a significant reduction in the median planning time, a 40% reduction from 3.7 to 2.2 hours (p = 0.002, pFDR = 0.032), and for the number of iterations, a 30% reduction from 8.5 to 6.0 (p = 0.006, pFDR = 0.047). The quality of plans from both approaches was comparable. From these preliminary results, vector-model-supported optimization can expedite the optimization of VMA-SRT for brain metastasis while maintaining plan quality.

2017-10-01

Full Text Available Pulmonary squamous cell carcinoma is the second most common non–small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding.

Purpose: To compare the outcome of surgical resection followed by whole brain radiotherapy (WBRT) with WBRT alone in patients treated for single brain metastasis. Methods and Materials: The data from 195 patients with single brain metastases were retrospectively evaluated. Of the 195 patients, 99 underwent resection of the metastasis followed by WBRT and 96 underwent WBRT alone. Seven additional potential prognostic factors were investigated: age, gender, Eastern Cooperative Oncology Group performance score, tumor type, interval between initial tumor diagnosis and WBRT, extracranial metastases, and recursive partitioning analysis class. Both treatment groups were well balanced for these factors. Results: On multivariate analysis, improved survival was associated with resection (relative risk [RR], 1.20; 95% confidence interval [CI], 1.11-1.31; p < 0.001), lower recursive partitioning analysis class (RR, 1.58; 95% CI, 1.22-2.06; p < 0.001), age ≤61 years (RR, 1.79; 95% CI, 1.23-2.61; p = 0.002), Eastern Cooperative Oncology Group performance score of 0-1 (RR, 2.47; 95% CI, 1.70-3.59; p < 0.001), and the absence of extracranial metastases (RR, 1.99; 95% CI, 1.41-2.79; p < 0.001). Improved local control was associated with resection (RR, 1.25; 95% CI, 1.11-1.41; p < 0.001) and age ≤61 years (RR, 1.77; 95% CI, 1.09-2.88; p = 0.020). Improved brain control distant from the original site was associated with lower recursive partitioning analysis class (RR, 1.65; 95% CI, 1.03-2.69; p < 0.035), age ≤61 years (RR, 1.81; 95% CI, 1.12-2.96; p = 0.016), and the absence of extracranial metastases (RR, 2.42; 95% CI, 1.52-3.88; p < 0.001). Improved control within the entire brain was associated with surgery (RR, 1.24; 95% CI, 1.12-1.38; p < 0.001) and age ≤61 years (RR, 1.83; 95% CI, 1.21-2.77; p = 0.004). Conclusion: In patients with a single brain metastasis, the addition of resection to WBRT improved survival, local control at the original metastatic site, and control

A 58-year-old man underwent right lower lobectomy for lung adenocarcinoma in June 1998. Since a high level of tumor marker CEA persisted after surgery, chemotherapy was additionally performed, and the CEA level subsequently normalized. However, the CEA level increased in April 1999, and brain metastasis was found in the left occipital lobe, and the first gammaknife irradiation was performed. Multiple brain metastases were found when CEA increased again in August 1999, and the second gammaknife irradiation was performed. Moreover, brain metastases were found in the left frontal and occipital lobes in February 2000, and the third gammaknife irradiation was performed. CEA normalized thereafter, but increased in February 2001. Brain metastasis was found in the right occipital lobe, and the fourth gammaknife irradiation was performed. CEA has remained within the normal range for about 4 years thereafter. Long-term survival was possible by repeated gammaknife irradiation for brain metastases. Monitoring of CEA played an important role in finding recurrent brain metastasis in this patient.

Patients with metastatic tumors to the brain have a very poor prognosis. Increased metastatic potential has been associated with the fibrinolytic system. We investigated the role of the fibrinolytic enzyme plasmin in tumor cell migration across brain endothelial cells and growth of brain metastases in an experimental metastatic melanoma model. Metastatic tumors to the brain were established by direct injection into the striatum or by intracarotid injection of B16F10 mouse melanoma cells in C57Bl mice. The role of plasminogen in the ability of human melanoma cells to cross a human blood-brain barrier model was studied on a transwell system. Wild type mice treated with the plasmin inhibitor epsilon-aminocaproic acid (EACA) and plg -/- mice developed smaller tumors and survived longer than untreated wild type mice. Tumors metastasized to the brain of wild type mice treated with EACA and plg -/- less efficiently than in untreated wild type mice. No difference was observed in the tumor growth in any of the three groups of mice. Human melanoma cells were able to cross the human blood-brain barrier model in a plasmin dependent manner. Plasmin facilitates the development of tumor metastasis to the brain. Inhibition of the fibrinolytic system could be considered as means to prevent tumor metastasis to the brain

The brain is a metastatic organ that is most prone to lung adenocarcinoma (LAC). However, the prognosis of patients with brain metastasis remains very poor. In this study, we evaluated the efficacy of icotinib plus whole brain radiation therapy (WBRT) for treating patients with brain metastasis from epidermal growth factor receptor (EGFR)-mutated LAC. All patients received standard WBRT administered to the whole brain in 30 Gy in 10 daily fractions. Each patient was also instructed to take 125 mg icotinib thrice per day beginning from the first day of the WBRT. After completing the WBRT, maintenance icotinib was administered until the disease progressed or intolerable adverse effects were observed. Cranial progression-free survival (CPFS) and overall survival (OS) times were the primary endpoints. A total of 43 patients were enrolled in this study. Two patients (4.7%) presented a complete response (CR), whereas 20 patients (46.5%) presented a partial response (PR). The median CPFS and OS times were 11.0 and 15.0 months, respectively. The one-year CPFS rate was 40.0% for the patients harboring EGFR exon 19 deletion and 16.7% for the patients with EGFR exon 21 L858R (P=0.027). The concurrent administration of icotinib and WBRT exhibited favorable effects on the patients with brain metastasis. EGFR exon 19 deletion was predictive of a long CPFS following icotinib plus WBRT.

Merkel cell carcinoma is a rare skin tumor of neural crest origin and is part of the amine precursor uptake and decarboxylase system. It typically occurs on the face of elderly people. Distant metastasis is almost uniformly fatal. Choroidal metastasis, to our knowledge, has not been described. We report a patient with Merkel cell carcinoma who had a synchronous solid choroidal tumor and a biopsy-proven brain metastasis. Our 56-year-old patient presented with a rapidly growing, violaceous preauricular skin tumor. Computed tomography of the head disclosed incidental brain and choroidal tumors. Light and electron microscopy of biopsy specimens of both the skin and the brain lesions showed Merkel cell carcinoma. Ophthalmoscopy, fluorescein angiography, and A and B echography revealed a solid choroidal mass. The brain and skin tumors responded well to irradiation. A radioactive episcleral plaque was applied subsequently to the choroidal tumor. All tumors regressed, and the patient was doing well 28 months later. To our knowledge this is the first case of presumed choroidal metastasis of Merkel cell carcinoma

Metastatic brain tumors from colorectal cancers are relatively rare. In previous reports, the incidence ranged from 3 to 5 percent of all metastatic brain tumors. We report 7 cases of metastatic brain tumors from colorectal cancers. The time interval from the diagnosis of the primary tumors to the brain metastasis was 3 years on the average. Metastasis to the lung and liver were also found in 6 cases at the time of the diagnosis of the brain metastasis. The CEA levels in the serum were highly elevated in all cases. Solitary metastasis was found in all cases; cancers tend to metastasize in the deep area of the cerebrum or cerebellum. On a plain CT scan, tumors were demonstrated as ring-type, with a high-density mass, and ring-like enhancement was seen in 6 cases. Prognosis was very poor in most cases. The median survival time from diagnosis of brain metastasis was 4.5 months in the 2 cases with surgery and 3.5 months in the 4 cases without surgery.

Glioblastoma multiforme (GBM) is characterized by extensive local invasion, which is in contrast with extremely rare systemic metastasis of GBM. Molecular mechanisms inhibiting systemic metastasis of GBM would be a novel therapeutic candidate for GBM in the brain. Patient-derived GBM cells were primarily cultured from surgical samples of GBM patients and were inoculated into the brains of immune deficient BALB/c-nude or NOD-SCID IL2Rgamma(null) (NSG) mice. Human NK cells were isolated from peripheral blood mononucleated cells and expanded in vitro. Patient-derived GBM cells in the brains of NSG mice unexpectedly induced spontaneous lung metastasis although no metastasis was detected in BALB/c-nude mice. Based on the difference of the innate immunity between two mouse strains, NK cell activities of orthotopic GBM xenograft models based on BALB/c-nude mice were inhibited. NK cell inactivation induced spontaneous lung metastasis of GBM cells, which indicated that NK cells inhibit the systemic metastasis. In vitro cytotoxic activities of human NK cells against GBM cells indicated that cytotoxic activity of NK cells against GBM cells prevents systemic metastasis of GBM and that NK cells could be effective cell therapeutics against GBM. Accordingly, NK cells transplanted into orthotopic GBM xenograft models intravenously or intratumorally induced apoptosis of GBM cells in the brain and showed significant therapeutic effects. Our results suggest that innate NK immunity is responsible for rare systemic metastasis of GBM and that sufficient supplementation of NK cells could be a promising immunotherapeutic strategy for GBM in the brain.

Full Text Available Most breast masses arise from the breast. Metastasis to the breast is fairly uncommon, but can occur in breast skin and parenchyma. In particular, leukemia and lung cancers, and MM may metastasize to the breast. Breast metastasis might be the first symptom or may occur during the course of other malignancies. Our case presented with a fixed mass in the upper-medial quadrant of her left breast during regular follow-up visits. The mean time to breast metastasis in patients with MM is 62 months (13-178. In our case this time was 48 months. In a case series with 7 patients hematological malignancies (Hodgkin lymphoma, non-Hodgkin lymphoma, and leukemia were the leading cause of breast metastasis, whereas in only 1 case the cause was MM. In another case series of 15 MM patients with metastasis to the breast, the primary tumor was frequently localized to the upper extremities and trunk. In a report of 250 conjunctival MM cases the mortality rate was significantly higher in patients with tumors >4 mm in vertical thickness. In another 45-case MM series tumors with a diameter >10 mm were associated with higher mortality rates. In our case the thickness of the tumor was 5 mm. In conclusion, histopathological evaluation should be mandatory in patients with known primary malignancies in order to differentiate new primary tumors, metastases, and benign tumors.

Brain metastasis (BM) is common in patients with breast cancer. Predicting patient survival is critical for the clinical management of breast cancer brain metastasis (BCBM). The present study was designed to develop and evaluate a prognostic model for patients with newly diagnosed BCBM. Based on the clinical data of patients with BCBM treated in the Affiliated Hospital of Academy of Military Medical Sciences (Beijing, China) between 2002 and 2014, a nomogram was developed to predict survival using proportional hazards regression analysis. The model was validated internally by bootstrapping, and the concordance index (c-index) was calculated. A calibration curve and c-index were used to evaluate discriminatory and predictive ability, in order to compare the nomogram with widely used models, including recursive partitioning analysis (RPA), graded prognostic assessment (GPA) and breast-graded prognostic assessment (Breast-GPA). A total of 411 patients with BCBM were included in the development of this predictive model. The median overall survival time was 14.1 months. Statistically significant predictors for patient survival included biological subtype, Karnofsky performance score, leptomeningeal metastasis, extracranial metastasis, the number of brain metastases and disease-free survival. A nomogram for predicting 1- and 2-year overall survival rates was constructed, which exhibited good accuracy in predicting overall survival with a concordance index of 0.735. This model outperformed RPA, GPA and Breast-GPA, based on the comparisons of the c-indexes. The nomogram constructed based on a multiple factor analysis was able to more accurately predict the individual survival probability of patients with BCBM, compared with existing models.

The clinical course and prognostic factors of HER2-positive breast cancer patients with brain metastases are not well known because of the relatively small population. The aim of this study was to determine prognostic factors associated with HER2-positive patients who develop brain metastases. This retrospective study assessed the largest dataset to date of 432 HER2-positive patients who were diagnosed with brain metastases from 24 institutions of the Japan Clinical Oncology Group, Breast Cancer Study Group. The median age of the 432 patients was 54 years (range, 20-86 years). Of the patients, 162 patients (37.5 %) had ER-positive/HER2-positive (ER+HER2+) breast cancer, and 270 (62.5 %) had ER-negative/HER2-positive (ER-HER2+) breast cancer. The median brain metastasis-free survival period from primary breast cancer was 33.5 months in both groups. The median survival after developing brain metastasis was 16.5 and 11.5 months in the ER+HER2+ and ER-HER2+ groups, respectively, (p = 0.117). Patients with >3 brain metastases had significantly shorter overall survival in both ER+HER2+ (p developing brain metastases was not associated with survival duration after developing brain metastases (p = 0.571). However, patients treated with both trastuzumab and lapatinib after developing metastasis had significantly longer survival than patients treated with trastuzumab alone, lapatinib alone, or no HER2-targeting agent (p brain metastases, regardless of the use of trastuzumab before developing brain metastasis, treatment with both trastuzumab and lapatinib might improve survival.

2013-01-01

Full Text Available Treatment outcomes for a patient with solitary brain metastasis after long-term relapse-free follow-up of invasive lung carcinoma were presented. Brain metastasis without other signs of disease progression was diagnosed 10 years after combined modality treatment for stage II lung cancer. Removal of intracerebral metastasis with intraoperative photodynamic therapy was performed. Histology microspecimens of the primary tumor and metastasis were similar. No signs of disease progression in the brain 9 months after surgery were found. This case demonstrates that it is important to increase cancer suspicion for patients with long-term relapse-free follow-up. The use of intraoperative photodynamic therapy with photoditazine as a sensitizer in the treatment of cerebral metastases results in a favorable anti-tumor effect, thus improving life quality of patients

Management of lung cancer brain metastasis: An overview

Himanshu Srivastava

2017-01-01

Full Text Available With the improvements in systemic treatment for lung cancer, distant metastasis to sanctuary sites such as brain has become an increasingly more important issue. The management of these patients consists of supportive care and disease-directed treatment. Combined modality treatment (surgical resection or radiosurgery, followed by whole brain radiotherapy of brain metastases has greatly improved the local control of disease in patients with single lesion, good functional performance status, and controlled extracranial disease as demonstrated in prospective randomized studies. For patients with multiple brain metastases, conventional fractionated whole brain radiotherapy continues to be a standard and efficacious treatment. At present, experience with the use of molecularly targeted tyrosine kinase inhibitors in nonsmall cell lung cancer patients with activating mutations in the epidermal growth factor receptor gene and anaplastic lymphoma kinase gene is growing. However, their effectiveness in patients with brain metastases is not well established. In the arena of targeted therapies, vascular endothelial growth factor pathway inhibitors such as bevacizumab have shown some activity in brain metastases. Further prospective studies are necessary to facilitate selection of patient subpopulation for targeted agents in future studies.

Brain metastases confer significant morbidity and a poorer survival in non-small cell lung cancer (NSCLC). Vascular endothelial growth factor-targeted antiangiogenic therapies (AAT) have demonstrated benefit for patients with metastatic NSCLC and are expected to directly inhibit the pathophysiology and morbidity of brain metastases, yet patients with brain metastases have been excluded from most clinical trials of AAT for fear of intracranial hemorrhage (ICH). The underlying risk of ICH from NSCLC brain metastases is low, but needs to be quantitated to plan clinical trials of AAT for NSCLC brain metastases. Data from MD Anderson Cancer Center Tumor Registry and electronic medical records from January 1998 to March 2006 was interrogated. Two thousand one hundred forty-three patients with metastatic NSCLC registering from January 1998 to September 2005 were followed till March 2006. Seven hundred seventy-six patients with and 1,367 patients without brain metastases were followed till death, date of ICH, or last date of study, whichever occurred first. The incidence of ICH seemed to be higher in those with brain metastasis compared with those without brain metastases, in whom they occurred as result of cerebrovascular accidents. However, the rates of symptomatic ICH were not significantly different. All ICH patients with brain metastasis had received radiation therapy for them and had been free of anticoagulation. Most of the brain metastasis-associated ICH's were asymptomatic, detected during increased radiologic surveillance. The rates of symptomatic ICH, or other cerebrovascular accidents in general were similar and not significantly different between the two groups. In metastatic NSCLC patients, the incidence of spontaneous ICH appeared to be higher in those with brain metastases compared with those without, but was very low in both groups without a statistically significant difference. These data suggest a minimal risk of clinically significant ICH for NSCLC

Brain metastasis is a common cause of mortality in cancer patients, yet potential therapeutic targets remain largely unknown. The type I insulin-like growth factor receptor (IGF-IR) is known to play a role in the progression of breast cancer and is currently being investigated in the clinical setting for various types of cancer. The present study demonstrates that IGF-IR is constitutively autophosphorylated in brain-seeking breast cancer sublines. Knockdown of IGF-IR results in a decrease of phospho-AKT and phospho-p70s6k, as well as decreased migration and invasion of MDA-MB-231Br brain-seeking cells. In addition, transient ablation of IGFBP3, which is overexpressed in brain-seeking cells, blocks IGF-IR activation. Using an in vivo experimental brain metastasis model, we show that IGF-IR knockdown brain-seeking cells have reduced potential to establish brain metastases. Finally, we demonstrate that the malignancy of brain-seeking cells is attenuated by pharmacological inhibition with picropodophyllin, an IGF-IR-specific tyrosine kinase inhibitor. Together, our data suggest that the IGF-IR is an important mediator of brain metastasis and its ablation delays the onset of brain metastases in our model system.

Control of non-small-cell lung cancer (NSCLC) with brain metastasis is clinically challenging. This study retrospectively evaluated the efficacy of different adjuvant therapies for 776 cases of advanced NSCLCs with brain metastasis who treated with chemotherapy, chemotherapy plus bevacizumab, tyrosine kinase inhibitor (TKI) alone, or supportive care. The median progression-free survival (mPFS) and median overall survival (mOS) of patients treated with chemotherapy plus bevacizumab were 8.5 and 10.5 months, respectively, which were better than those of patients treated with other three therapies(P chemotherapy plus bevacizumab but was significantly better than that of other therapies. Moreover, for patients with EGFR wild-type NSCLC, the mPFS and mOS after chemotherapy plus bevacizumab were greater than those with other two therapies (P Chemotherapy plus bevacizumab was more effective for NSCLC patients with brain metastasis. Further studies will investigate the benefit of TKI alone for patients with EGFR-mutated. For patients with EGFR wild-type, chemotherapy plus bevacizumab did improve PFS and OS. Furthermore, regimens including pemetrexed led to a greater RR.

Glioblastoma is the most common primary malignant brain tumor. Extraneural metastases are rarely reported in the literature. We report a case of a 38-year-old patient who was diagnosed with glioblastoma in 2015. Four months after surgery, local relapse was found and the patient received a second surgery. After another 4 months, we found a hard mass in the right posterior neck when she admitted to our department for fourth cycle of adjuvant chemotherapy. Immunohistochemical investigation supported the diagnosis of glioblastoma metastases to the neck after resection of the right neck mass. A few days later, spinal vertebral magnetic resonance imaging (MRI) confirmed multiple metastases in the thoracic, lumbar, sacral, and bilateral iliac bones. Glioblastoma is the most common primary malignant brain tumor. Whole tumor resection and early radiotherapy and chemotherapy can delay recurrence and prolong survival. Extracranial metastases are extremely rare. We report this case with the aim of bringing attention to extracranial metastasis of brain glioma.

2008-01-01

Ewing's sarcoma is a malignant bone tumor that can occur anywhere in the body, but it is most commonly observed in the long bones of the arms and legs, the pelvis and in the chest. The predominant sites of metastasis include the lung (38%), bone (including the spine; 31%), and the bone marrow (11%). Metastasis of Ewing's sarcoma to the central nervous system (CNS) is relatively rare, and most of the previous reports have demonstrated involvement of the bony calvarium or brain parenchyma. We describe here the imaging findings of dural metastasis of Ewing's sarcoma, and these imaging findings have not been previously reported on in the medical literature. In conclusion, dural metastasis of Ewing's sarcoma is very rare and its imaging characteristics are similar to those of a primary tumor, which mimic the findings of a schwannoma or meningioma. Despite its rarity, secondary Ewing's sarcoma may be included in the differential diagnosis of extra-axial dural masses

Invasive lobular carcinomas are the second most common type (5% to 15%) of invasive breast carcinomas. The most frequent sites of breast cancer metastasis are the local and distant lymph nodes, brain, lung, liver, and bones; metastasis to the gastrointestinal system, especially to the stomach, is rare. When a mass is detected in an unusual place in a patient with invasive lobular carcinoma, it should be kept in mind that such a mass may be either a second primary carcinoma or the metastasis of an invasive lobular carcinoma. In this report, we present a case of gastric metastasis from triple-negative invasive lobular breast cancer. It is important to make an accurate diagnosis by distinguishing gastric metastasis from breast cancer in order to select the best initial treatment for systemic diseases of breast cancer. Considering our case, healthcare professionals should take into account that cases with invasive lobular breast cancer may experience unusual metastases.

Other malignant tumor metastasis to the kidney is very unusual. Primary cervical cancer metastasis to adjacent pelvic organs and lymph nodes are well known followed by abdominal solid organs such as the liver and adrenal glands. However, reported primary cervical cancer metastasis to the kidney is extremely rare and mostly appeared as bilateral multiple renal masses. We report here on a rare case of unilateral single renal metastasis from primary cervical cancer after concur- rent chemoradiotherapy.

Metastasis to the pituitary gland is extremely rare and is often detected incidentally by symptoms associated with endocrine dysfunction. Breast and lung cancer are the most common primary metastasizing to pituitary gland. Metastasis from hepatocellular carcinoma to the pituitary gland is extremely rare, with only 10 cases having been previously reported. We present here the first case of pituitary metastasis of hepatocellular carcinoma presenting with panhypopituitarism diagnosed by magnetic resonance imaging. We report the case of an 80-year-old Japanese woman who presented with the sudden onset of hypotension and bradycardia after having previously been diagnosed with hepatocellular carcinoma. Based on low levels of pituitary hormones, she was diagnosed with panhypopituitarism caused by metastasis of the hepatocellular carcinoma to the pituitary gland. Magnetic resonance imaging with arterial spin-labeling was effective in the differential diagnosis of the intrasellar tumor. The patient died despite hormone replacement therapy because of hypovolemic shock. Metastasis to the pituitary gland causes various non-specific symptoms, so it is difficult to diagnose. The present case emphasizes the importance of diagnostic imaging in identifying these metastases. Clinicians should consider the possibility of pituitary metastasis in patients with malignant tumors who demonstrate hypopituitarism

Full Text Available Although splenic metastasis is fairly common in disseminated cancer, solitary splenic metastasis in the absence of diffuse dissemination is rare. We report a case of 44 year-old man who developed isolated splenic metastasis of colon cancer. The patient had undergone right sided hemicolectomy for colon cancer in 1988. In 2001, he underwent reoperation because of local recurrence of tumor in the anastomotic site. The patient was admitted to our hospital on Sep 2003 with abdominal pain. Chest X-ray was normal. Abdominal CT scan showed a large cystic lesion in the spleen. Splenectomy was performed for the patient. The spleen was enlarged, firm and irregular. Histological examination showed metastatic mucinous adenocarcinoma. Based on this case, we recommend that clinicians consider possibility of metastasis in cystic lesions of spleen, especially in patients with a history of a malignant disease.

Radiosurgery is a noninvasive procedure where spatially accurate and highly conformal doses of radiation are targeted at brain lesions with an ablative intent. Recently, radiosurgery has been established as an effective technique for local treatment of brain metastasis. After radiosurgery, magnetic resonance (MR) imaging plays an important role in the assessment of the therapeutic response and of any complications. The therapeutic approach depends on the imaging findings obtained after radiosurgery, which have a role in the decision making to perform additional invasive modalities (repeat resection, biopsy) to obtain a definite diagnosis and to improve the survival of patients. Conventional MR imaging findings are mainly based on morphological alterations of tumors. However, there are variable imaging findings of radiation-induced changes including radiation necrosis in the brain. Radiologists are sometimes confused by radiation-induced injuries, including radiation necrosis, that are seen on conventional MR imaging. The pattern of abnormal enhancement on follow-up conventional MR imaging closely mimics that of a recurrent brain metastasis. So, classifying newly developed abnormal enhancing lesions in follow-up of treated brain metastasis with correct diagnosis is one of the key goals in neuro-oncologic imaging. To overcome limitations of the use of morphology-based conventional MR imaging, several physiological-based functional MR imaging methods have been used, namely diffusion-weighted imaging, perfusion MR imaging, and proton MR spectroscopy, for the detection of hemodynamic, metabolic, and cellular alterations. These imaging modalities provide additional information to allow clinicians to make proper decisions regarding patient treatment.

Full Text Available Metastatic tumors account for 1% of all oral malignancies. Metastasis to jaw bones is common, particularly in the mandible, rare in the oral soft tissues, and account for only 0.1% of oral malignancies. The majority of metastatic cases (70% reported in the literature have primary tumors located in the lung, breast, kidney, and colon. Metastasis is a biological complex process that involves detachment from the surrounding cells, regulation of cell motility, invasion, survival, proliferation, and evasion of the immune system. Clinical presentation of metastatic tumors is variable, which may create diagnostic dilemma or may lead to erroneous diagnosis. Metastatic tumors clinically mimic as dental infections. Metastasis to the oral soft tissue from lung cancer, especially gingiva is a rare condition. Metastasis to the gingiva can affect the oral function, speech, and nutrition. Most of the cases in the literature reported that lesion presented in oral soft tissues before the diagnosis of primary tumors. Here we report a case of 62-year-old male patient with metastasis from lung to the gingiva, where the metastasis was detected before primary tumor.

We reported a case of port site metastasis in a 57-year-old patient who underwent video-assisted thoracic surgery (VATS) resection of pulmonary metastasis from breast cancer. Port site metastasis after VATS is very rare in patients with breast cancer. However, when suspicious lesions are detected near the port site in patients who have undergone VATS for pulmonary metastasis, port site metastasis should be considered in the differential diagnosis.

To compare and evaluate the possible advantages related to the use of VMAT and helical IMRT and two different modalities of boost delivering, adjuvant stereotactic boost (SRS) or simultaneous integrated boost (SIB), in the treatment of brain metastasis (BM) in RPA classes I-II patients. Ten patients were treated with helical IMRT, 5 of them with SRS after whole brain radiotherapy (WBRT) and 5 with SIB. MRI co-registration with planning CT was mandatory and prescribed doses were 30 Gy in 10 fractions (fr) for WBRT and 15Gy/1fr or 45Gy/10fr in SRS or SIB, respectively. For each patient, 4 "treatment plans" (VMAT SRS and SIB, helical IMRT SRS and SIB) were calculated and accepted if PTV boost was included in 95 % isodose and dose constraints of the main organs at risk were respected without major deviations. Homogeneity Index (HI), Conformal Index (CI) and Conformal Number (CN) were considered to compare the different plans. Moreover, time of treatment delivery was calculated and considered in the analysis. Volume of brain metastasis ranged between 1.43 and 51.01 cc (mean 12.89 ± 6.37 ml) and 3 patients had double lesions. V95% resulted over 95 % in the average for each kind of technique, but the "target coverage" was inadequate for VMAT planning with two sites. The HI resulted close to the ideal value of zero in all cases; VMAT-SIB, VMAT-SRS, Helical IMRT-SIB and Helical IMRT-SRS showed mean CI of 2.15, 2.10, 2.44 and 1.66, respectively (optimal range: 1.5-2.0). Helical IMRT-SRS was related to the best and reliable finding of CN (0.66). The mean of treatment time was 210 s, 467 s, 440 s, 1598 s, respectively, for VMAT-SIB, VMAT-SRS, Helical IMRT-SIB and Helical IMRT-SRS. This dosimetric comparison show that helical IMRT obtain better target coverage and respect of CI and CN; VMAT could be acceptable in solitary metastasis. SIB modality can be considered as a good choice for clinical and logistic compliance; literature's preliminary data are confirming also a

Purpose: Iodine-enhanced radiotherapy is an innovative treatment combining the selective accumulation of an iodinated contrast agent in brain tumors with irradiations using monochromatic medium energy x-rays. The aim of this study is to compare dynamic stereotactic arc-therapy and iodineenhanced SSRT. Methods: Five patients bearing brain metastasis received a standard helical 3D-scan without iodine. A second scan was acquired 13 min after an 80 g iodine infusion. Two SSRT treatment plans (with/without iodine) were performed for each patient using a dedicated Monte Carlo (MC) treatment planning system (TPS) based on the ISOgray TPS. Ten coplanar beams (6×6 cm2, shaped with collimator) were simulated. MC statistical error objective was less than 5% in the 50% isodose. The dynamic arc-therapy plan was achieved on the Iplan Brainlab TPS. The treatment plan validation criteria were fixed such that 100% of the prescribed dose is delivered at the beam isocentre and the 70% isodose contains the whole target volume. The comparison elements were the 70% isodose volume, the average and maximum doses delivered to organs at risk (OAR): brainstem, optical nerves, chiasma, eyes, skull bone and healthy brain parenchyma. Results: The stereotactic dynamic arc-therapy remains the best technique in terms of dose conformation. Iodine-enhanced SSRT presents similar performances to dynamic arc-therapy with increased brainstem and brain parenchyma sparing. One disadvantage of SSRT is the high dose to the skull bone. Iodine accumulation in metastasis may increase the dose by 20–30%, allowing a normal tissue sparing effect at constant prescribed dose. Treatment without any iodine enhancement (medium-energy stereotactic radiotherapy) is not relevant with degraded HDVs (brain, parenchyma and skull bone) comparing to stereotactic dynamic arc-therapy. Conclusion: Iodine-enhanced SSRT exhibits a good potential for brain metastasis treatment regarding the dose distribution and OAR criteria.

Purpose: Metastatic cancer to the brain is a major problem for the patients with bronchogenic carcinoma, and most of these patients have a limited survival expectancy. To increase tumor control and/or to decrease late morbidity with possible shortening in over-all treatment period, multiple daily fraction technique for brain metastasis was performed. The author represented the results of accelerated fractionation radiotherapy in patients with brain metastases from non-small cell lung cancer. Materials and Methods: Twenty-six patients with brain metastases from non-small cell lung cancer between 1991 and 1993 received brain radiotherapy with a total dose of 48 Gy, at 2 Gy per fraction, twice a day with a interfractional period of 6 hours, and delivered 5 days a week. The whole brain was treated to 40 Gy and boost dose escalated to 8 Gy for single metastatic lesion by reduced field. Twenty-four of the 26 patients completed the radiotherapy. Radiotherapy was interrupted in two patients suggesting progressive intracerebral disease. Results: This radiotherapy regimen appears to be comparable to the conventional schema in relief from symptoms. Three of the 24 patients experienced nausea and or vomiting during the course of treatment because of acute irradiation toxicity. The author observed no excessive toxicity with escalating dose of irradiation. An increment in median survival, although not statistically significant (p>0.05), was noted with escalating doses(48 Gy) of accelerated fractionation (7 months) compared to conventional treatment(4.5 months). Median survival also increased in patients with brain solitary metastasis(9 months) compared to multiple extrathoracic sites(4 months), and in patients with good performance status(9 months versus 3.5 months), they were statistically significant(p<0.01). Conclusion: The increment in survival in patients with good prognostic factors such as controlled primary lesion, metastasis in brain only, and good performance status

Full Text Available Bone and soft tissue malignancies account for a small portion of brain metastases. In this review, we characterize their incidence, treatments, and prognosis. Most of the data in the literature is based on case reports and small case series. Less than 5% of brain metastases are from bone and soft tissue sarcomas, occurring most commonly in Ewing’s sarcoma, malignant fibrous tumors, and osteosarcoma. Mean interval from initial cancer diagnosis to brain metastasis is in the range of 20–30 months, with most being detected before 24 months (osteosarcoma, Ewing sarcoma, chordoma, angiosarcoma, and rhabdomyosarcoma, some at 24–36 months (malignant fibrous tumors, malignant peripheral nerve sheath tumors, and alveolar soft part sarcoma, and a few after 36 months (chondrosarcoma and liposarcoma. Overall mean survival ranges between 7 and 16 months, with the majority surviving < 12 months (Ewing’s sarcoma, liposarcoma, malignant fibrous tumors, malignant peripheral nerve sheath tumors, angiosarcoma and chordomas. Management is heterogeneous involving surgery, radiosurgery, radiotherapy, and chemotherapy. While a survival advantage may exist for those given aggressive treatment involving surgical resection, such patients tended to have a favorable preoperative performance status and minimal systemic disease.

Choroidal metastasis from colorectal cancer is rare, and there have been no reported cases of such metastasis from early colorectal cancer. We report a case of choroidal metastasis from early rectal cancer. A 61 year-old-man experienced myodesopsia in the left eye 2 years and 6 months after primary rectal surgery for early cancer, and was diagnosed with left choroidal metastasis and multiple lung metastases. Radiotherapy was initiated for the left eye and systemic chemotherapy is initiated for the multiple lung metastases. The patient is living 2 years and 3 months after the diagnosis of choroidal metastasis without signs of recurrence in the left eye, and continues to receive systemic chemotherapy for multiple lung metastases. Current literatures have few recommendations regarding the appropriate treatment of choroidal metastasis from colorectal cancer, but an aggressive multi-disciplinary approach may be effective in local regression. This is the first report of choroidal metastasis from early rectal cancer. We consider it important to enforce systemic chemotherapy in addition to radiotherapy for choroidal metastasis from colorectal cancer. Copyright © 2014 The Authors. Published by Elsevier Ltd..

A 65-year-old woman underwent surgery for right breast cancer (TIN1aM0) in December 2005. In March 2011, the breast cancer recurred with multiple lung and lymph node metastases. In February 2013, because of multiple brain metastases whole-brain radiation therapy was performed. In January 2014, she developed paralysis of the left leg. Spinal cord magnetic resonance imaging revealed a mass lesion (Th12 to L1 level) in the spinal cord, and she was diagnosed with intramedullary spinal cord metastasis (ISCM) from the breast cancer. Spinal cord irradiation reduced the metastasis and improved her paralysis. Although pharmacotherapy was continued, her metastases, with the exception of ISCM, progressed and she died of the disease in November 2014. It is necessary to diagnose ISCM at the time of its onset. Additionally immediate therapeutic intervention can significantly reduce the volume of ISCM, resulting in symptomatic relief from neurological deficit; in this case, radiation therapy was effective.

Introduction: Recurrent oculomotor nerve palsies are extremely rare clinical conditions. Case report: Here, we report on a unique case of a short-lasting recurrent unilateral incomplete external and complete internal oculomotor nerve palsy. The episodic palsies were probably caused by an ipsilateral mesencephalic metastasis of a breast carcinoma and occurred after successful brain radiation therapy. Discussion: While the pathogenic mechanism remains unclear, the recurrent sudden onset and disappearance of the palsies and their decreasing frequency after antiepileptic treatment suggest the occurrence of epilepsy-like brainstem seizures. A review of case reports of spontaneous reversible oculomotor nerve palsies is presented. PMID:25104947

Full Text Available We report a case of pregnancy-associated breast cancer with metastasis to the brain, likely resulting from hereditary breast and ovarian cancer (HBOC. A 35-year-old woman (gravida 2, para 0-1-0-1 underwent a right mastectomy and right axillary dissection after a cesarean section at 30 years of age; her mother died at 47 years of age due to breast cancer. Histopathological examination indicated an invasive ductal carcinoma with triple-negative cancer (cancer stage 2B [pT3N0M0]. The patient refused adjuvant therapy because of the risk of infertility. After 4 years, she became pregnant naturally. At 18 weeks’ gestation, she experienced aphasia and dyslexia due to brain metastasis. The pregnancy was terminated at 21 weeks’ gestation after thorough counseling. Her family history, young-onset disease, and histopathological findings suggested HBOC. She declined genetic testing for BRCA1/2, though genetic counseling was provided. In cases of pregnancy-related breast cancer, consideration must be given to whether the pregnancy should be continued and to posttreatment fertility. HBOC should also be considered. Genetic counseling should be provided and the patient should be checked for the BRCA mutation, as it is meaningful for the future of any potential children. Genetic counseling should be provided even if the cancer is advanced or recurrent.

Full Text Available Papillary thyroid carcinoma (PTC metastasis to distant organs is rare and mainly includes lung and bone. Metastasis affecting oral and maxillofacial region is extremely rare. We describe a case of PTC metastasis to cheek. The patient presented with a painless swelling of the left cheek with a history of total thyroidectomy for papillary carcinoma thyroid 5 years back. Cheek metastasis from papillary carcinoma thyroid is extremely rare. To the best of our knowledge, this is the first recorded instance of cheek metastasis from PTC. Common malignancies can metastasize to unusual sites and although infrequent, may be the presenting feature. The successful management of such cases may be achieved by a multidisciplinary approach.

In 113 of 422 patients with metastatic/recurrent breast cancer (MBC who were treated in our hospital after 2001, brain/meningeal metastasis was detected. In 240 patients who died, the overall incidence of brain/meningeal metastasis was 36.3% (n=87). With respect to hormone receptor (HR) and HER2 presence, metastasis was detected in 32 (58.2%) of 55 patients showing HR(-) and HER2(+), 17 (39.5%) of 43 patients showing HR(-) and HER2(-), 19 (31.5%) of 54 patients showing HR(+) and HER2(+), and 17 (20%) of 85 patients showing HR(+) and HER2(-) (brain metastasis was detected in 2 of 3 patients in whom HR or HER2 was unclear); the incidence was significantly higher in HR(-) or HER2(+) patients. Of our series including surviving patients, asymptomatic brain metastasis was detected using contrast-enhanced MRI in 24 HER2(+) patients. In the above 113 patients, the median survival time (MST) after diagnosis was 10 months. However, it was 17 months in 24 patients who underwent screening. For treatment, whole brain radiotherapy (WBRT) or stereotactic radiosurgery (SRS) mainly with a gamma knife was performed. During a follow-up of more than 12 months, 1 to 4 sessions of treatment (mean: 2.39, median: 2) were required. In 50% of the patients, both WBRT and SRS were performed. There were no HR- or HER2- related differences in survival after brain metastasis. However, the MST was 34 months in 7 patients in whom the 1st relapse site involved the brain. In the future, the usefulness of early treatment via brain metastasis screening should be reviewed in HR(-) and HER2(+) patients. (author)

Melanoma brain metastases presenting as delirium: a case report

Full Text Available Abstract Background Metastatic tumours sometimes present with neuropsychiatric symptoms, however psychiatric symptoms as rarely the first clinical manifestation. Cutaneous melanoma is the third most common cause of brain metastasis, with known risk factors increasing the chance of such central nervous system metastization. Objectives We present a clinical report of delirium as the first clinical manifestation of melanoma brain metastases, illustrating the relevance of an adequate and early differential diagnosis. Methods In addition to describing the clinical case, searches were undertaken in PubMed and other databases using keywords such as “brain metastasis”, “melanoma”, “agitation”, “psychiatric” and “delirium”. Results We here report the case of a 52-year-old female patient evaluated by Liaison Psychiatry after sudden onset of delirium while admitted at the Gastroenterology Department to study a hypothesis of pancreatitis. A head CT scan identified brain metastases, and after further examination, including brain biopsy, melanoma brain metastization was confirmed. Discussion Some of the diagnostic challenges of psychiatric symptoms associated with secondary brain tumours are discussed, underlining the importance of an adequate differential diagnosis when working in Psychiatry Liaison.

Usually, left colon cancer metastasis concerns liver, abdominal lymph nodes and lungs. Other localizations are quite rare occurrences. In spite of this, some uncommon metastasis sites are reported in literature, such as: peritoneum, ovaries, uterus, kidney testis, bones, thyroid, oral cavity and central nervous system. We report two cases of unusual localizations of left colon cancer metastasis localization, one into the retroperitoneal space and the other at the left axillary lynphnodes and between liver and pancreas. In the first reported case the diffusion pathway may have been the lymphatic mesocolic vessels, partially left in place from the previous surgery. In the second case the alleged metastatic lane may have been through the periumbilical lymph nodes to the parasternal lymph nodes and then to the internal mammary ones, finally reaching the axillary limph nodes.

Full Text Available The incidence of secondary neoplasms of the testis during autopsies is approximately 2.5%. Although most secondary testicular metastases are due to prostate cancer, only a few patients with prostate cancer have clinically manifested testicular metastasis. We report the case of a prostate cancer patient with testicular metastasis who was diagnosed after the presence of a palpable mass in the right testis. A 56-year-old Japanese male presented to our hospital with an elevated serum prostate-specific antigen (PSA level of 137 ng/ml. He was diagnosed with stage IV (T3N1M1b prostate cancer and received androgen deprivation therapy, followed by various hormonal manipulations. His serum PSA level was undetectable for 1 year. No distant metastases were detected during imaging examinations. He received radiation therapy; however, his serum PSA level increased gradually. Four months later, he presented with right testicular swelling. Computed tomography revealed a heterogenous mass in the right testis and a right high inguinal orchiectomy was performed. Histopathological analysis showed that the right testis was infiltrated with metastatic adenocarcinoma with a Gleason score of 8. This is a rare case of right testicular metastasis in a patient with prostate cancer. Testicular metastasis of prostate cancer can be aggressive and metastasize.

Cerebral Metastasis from a Previously Undiagnosed Appendiceal Adenocarcinoma

Full Text Available Brain metastases arise in 10%–40% of all cancer patients. Up to one third of the patients do not have previous cancer history. We report a case of a 67-years-old male patient who presented with confusion, tremor, and apraxia. A brain MRI revealed an isolated right temporal lobe lesion. A thorax-abdomen-pelvis CT scan showed no primary lesion. The patient underwent a craniotomy with gross-total resection. Histopathology revealed an intestinal-type adenocarcinoma. A colonoscopy found no primary lesion, but a PET-CT scan showed elevated FDG uptake in the appendiceal nodule. A right hemicolectomy was performed, and the specimen showed a moderately differentiated mucinous appendiceal adenocarcinoma. Whole brain radiotherapy was administrated. A subsequent thorax-abdomen CT scan revealed multiple lung and hepatic metastasis. Seven months later, the patient died of disease progression. In cases of undiagnosed primary lesions, patients present in better general condition, but overall survival does not change. Eventual identification of the primary tumor does not affect survival. PET/CT might be a helpful tool in detecting lesions of the appendiceal region. To the best of our knowledge, such a case was never reported in the literature, and an appendiceal malignancy should be suspected in patients with brain metastasis from an undiagnosed primary tumor.

Brain metastasis (BM) is a life-threatening event in breast cancer patients. Identifying patients at a high risk for BM can help to adopt screening programs and test preventive interventions. We tried to identify the incidence of BM in different stages and subtypes of breast cancer. We reviewed the clinical records of 2193 consecutive breast cancer patients who presented between January 1999 and December 2010. We explored the incidence of BM in relation to standard clinicopathological factors, and determined the cumulative risk of BM according to the disease stage and phenotype. Of the 2193 included women, 160 (7.3%) developed BM at a median follow-up of 5.8 years. Age younger than 60 years (P = .015), larger tumors (P = .004), lymph node (LN) positivity (P < .001), high tumor grade (P = .012), and HER2 positivity (P < .001) were associated with higher incidence of BM in the whole population. In patients who presented with locoregional disease, 3 factors independently predicted BM: large tumors (hazard ratio [HR], 3.60; 95% confidence interval [CI], 1.54-8.38; P = .003), axillary LN metastasis (HR, 4.03; 95% CI, 1.91-8.52; P < .001), and HER2 positivity (HR, 1.89; 95% CI, 1.0-3.41; P = .049). A Brain Relapse Index was formulated using those 3 factors, with 5-year cumulative incidence of BM of 19.2% in those having the 2 or 3 risk factors versus 2.5% in those with no or 1 risk factor (P < .001). In metastatic patients, 3 factors were associated with higher risk of BM: HER2 positivity (P = .007), shorter relapse-free interval (P < .001), and lung metastasis (P < .001). Disease stage and biological subtypes predict the risk for BM and subsequent treatment outcome. Copyright © 2017 Elsevier Inc. All rights reserved.

The purpose of this study was to compare Turbo-FLAIR imaging, T 2 -weighted imaging, and double-dose gadolinium-enhanced MR imaging in the detection of brain metastasis. Using the three sequences, 20 consecutive patients with brain metastases were prospectively studied with a 1.5-Tesla system. Three independent, blinded readers assessed the images for the presence, size, number, and location of metastatic lesions. In the detection of large lesions (>0.5 cm), Turbo-FLAIR imaging (38/48, 79%) was not significantly different from gadolinium-enhanced imaging (42/48, 88%) (p=0.273). T 2 -weighted imaging (31/48, 65%), however, was inferior to gadolinium-enhanced imaging (p<0.05). There was no difference between Turbo-FLAIR imaging and gadolinium-enhanced imaging in the accuracy of detecting solitary brain metastasis (4/4, 100%). In conclusion, Turbo-FLAIR imaging is a useful, noninvasive screening modality for brain metastasis. Its use may lead to cost savings in the diagnosis of brain metastases and may impact positively the cost-effectiveness of treatment. (author)

Anal metastasis from colorectal cancer rarely occurs, but it severely impairs the patient's quality of life, often requiring wide resection including the anal sphincter with permanent colostomy. This lesion can be misdiagnosed as a perianal fistula or an abscess, and it can be overlooked at the time of surgery because it is not included in the routine surgical extent of low anterior resection. We report two rare cases of anal metastasis from colorectal cancer. In both cases, perianal nodules with an internal solid portion were detected on preoperative rectal magnetic resonance imaging and additional local excisions of the anal lesions were performed during the process of treatment. Anal metastasis was pathologically confirmed by histology and immunohistochemical staining.

This study aimed to investigate the potential use of icotinib as first-line treatment to prevent brain metastasis from advanced lung adenocarcinoma. This investigation was designed as a retrospective nonrandomized controlled study. Enrolled patients received either icotinib or traditional chemotherapy as their first-line treatment. The therapeutic efficacy was compared among patients with advanced. (stages IIIB and IV) lung adenocarcinoma with epidermal growth factor receptor (EGFR)-sensitive mutation. The primary endpoint was the cumulative incidence of brain metastasis, whereas, the secondary endpoint was overall survival(OS). Death without brain metastasis was considered a competitive risk to calculate the cumulative risk of brain metastasis. Survival analysis was conducted using the Kaplan-Meier method and statistical significance was determined using the log-rank test. The present study included 396 patients with 131 in the icotinib group and 265 in the chemotherapy group. Among those with EGFR-sensitive mutation, the cumulative risk of brain metastasis was lower in the icotinib group than in the chemotherapy group. However, no significant difference in OS was observed between the two groups. Icotinib can effectively reduce the incidence of brain metastasis and therefore improve prognosis in advanced lung adenocarcinoma patients with EGFR.sensitive mutation.

Combined Therapy for Distant Metastasis of Sacral Chordoma

2015-01-01

Full Text Available Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40% of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, we will report a sacral chordoma case in which an intraperitoneal distant metastasis occurred and discuss the surgical approach.

To compare and evaluate the possible advantages related to the use of VMAT and helical IMRT and two different modalities of boost delivering, adjuvant stereotactic boost (SRS) or simultaneous integrated boost (SIB), in the treatment of brain metastasis (BM) in RPA classes I-II patients. Ten patients were treated with helical IMRT, 5 of them with SRS after whole brain radiotherapy (WBRT) and 5 with SIB. MRI co-registration with planning CT was mandatory and prescribed doses were 30 Gy in 10 fractions (fr) for WBRT and 15Gy/1fr or 45Gy/10fr in SRS or SIB, respectively. For each patient, 4 “treatment plans” (VMAT SRS and SIB, helical IMRT SRS and SIB) were calculated and accepted if PTV boost was included in 95 % isodose and dose constraints of the main organs at risk were respected without major deviations. Homogeneity Index (HI), Conformal Index (CI) and Conformal Number (CN) were considered to compare the different plans. Moreover, time of treatment delivery was calculated and considered in the analysis. Volume of brain metastasis ranged between 1.43 and 51.01 cc (mean 12.89 ± 6.37 ml) and 3 patients had double lesions. V95% resulted over 95 % in the average for each kind of technique, but the “target coverage” was inadequate for VMAT planning with two sites. The HI resulted close to the ideal value of zero in all cases; VMAT-SIB, VMAT-SRS, Helical IMRT-SIB and Helical IMRT-SRS showed mean CI of 2.15, 2.10, 2.44 and 1.66, respectively (optimal range: 1.5–2.0). Helical IMRT-SRS was related to the best and reliable finding of CN (0.66). The mean of treatment time was 210 s, 467 s, 440 s, 1598 s, respectively, for VMAT-SIB, VMAT-SRS, Helical IMRT-SIB and Helical IMRT-SRS. This dosimetric comparison show that helical IMRT obtain better target coverage and respect of CI and CN; VMAT could be acceptable in solitary metastasis. SIB modality can be considered as a good choice for clinical and logistic compliance; literature’s preliminary data are confirming

Thymic carcinomas are rare tumors that arise in the anterior mediastinum. Most of these malignancies develop local metastases limited in the thorax. Splenic metastases from thymic carcinomas are extremely rare. Here we report a case of isolated splenic metastasis from a 38-year-old female patient with Stage IV thymic carcinoma, who was treated with chemoradiotherapy. At twenty-2 months follow-up, the patient was found to have an isolated spleen metastasis, which was treated by Cyberknife with a reduced size of the metastasis, representing a partial response. Although splenic metastasis is a rare phenomenon, physicians need to be aware of the possibility of such metastases.

Ewing's sarcoma is a malignant bone tumor that can occur anywhere in the body, but it is most commonly observed in the long bones of the arms and legs, the pelvis and in the chest. The predominant sites of metastasis include the lung (38%), bone (including the spine; 31%), and the bone marrow (11%). Metastasis of Ewing's sarcoma to the central nervous system (CNS) is relatively rare, and most of the previous reports have demonstrated involvement of the bony calvarium or brain parenchyma. We describe here the imaging findings of dural metastasis of Ewing's sarcoma, and these imaging findings have not been previously reported on in the medical literature. In conclusion, dural metastasis of Ewing's sarcoma is very rare and its imaging characteristics are similar to those of a primary tumor, which mimic the findings of a schwannoma or meningioma. Despite its rarity, secondary Ewing's sarcoma may be included in the differential diagnosis of extra-axial dural masses.

2012-02-01

CONTEXT: Thyroid metastasis from pancreatic adenocarcinoma is extremely rare, with only two previous cases in the literature. We report a case of pancreatic adenocarcinoma metastasising to the thyroid. We review the incidence, diagnosis, and management of this rare occurrence. CASE REPORT: A 38-year-old man with a synchronous 6-month history of thyroid swelling, presented with epigastric pain and signs of obstructive jaundice. He was investigated by abdominal computerised tomography and endoscopic retrograde cholangiopancreatography. The diagnosis of pancreatic neoplasm was made. His thyroid neoplasm was investigated at another tertiary centre and thought to be a papillary neoplasm. He underwent a pancreaticoduodenectomy and recovered well post-operatively. Eight weeks later he had a total thyroidectomy. Histology confirmed that the thyroid mass was both morphologically and immunophenotypically similar to the pancreatic neoplasm. CONCLUSION: This case demonstrates the importance of a full investigation when a patient with suspected neoplastic history presents with a thyroid nodule. We outline the crucial role that immunohistochemistry plays in detecting and classifying primary and secondary thyroid neoplasms. The detection of a solitary thyroid metastasis from pancreatic adenocarcinoma may indicate a poor prognosis, and it is debatable whether resection of the primary should be undertaken when it presents with a solitary metastasis.

Primary urethral carcinoma is extremely rare, accounting for less than 1% of all female genitourinary tract cancers. To the best of our knowledge, this patient is the first reported case of primary urethral carcinoma presenting metastasis to eyes. The diagnosis of metastasis involving the choroids should be suspected in patient with history of carcinoma and a decreased visual acuity or any other visual symptom. Case presentation: A 43-year-old woman underwent a total hysterectomy, cystectomy and bilateral pelvic lymphadenectomy due a primary adenocarcinoma of the proximal urethra. Adjuvant pelvic radiotherapy and six cycles of chemotherapy using cisplatin were performed. The patient made follow-up with no evidence of oncologic disease. However, nine months later, the patient reported visual alterations. Ophthalmoloscopic examination showed choroid lesions in both eyes that were compatible with metastatic choroids tumor and nuclear magnetic resonance suggested bilateral retinal metastasis and left meningioma parasagittal in parietal region. She was undergoing a new palliative chemotherapy, but the disease developed and there were metastasis to bone four months later. The patient died fourteen months after the surgery. (author)

MO-FG-CAMPUS-TeP2-05: Optimizing Stereotactic Radiosurgery Treatment of Multiple Brain Metastasis Lesions with Individualized Rotational Arc Trajectories

International Nuclear Information System (INIS)

Dong, P; Xing, L; Ma, L

2016-01-01

Purpose: Radiosurgery of multiple (n>4) brain metastasis lesions requires 3–4 noncoplanar VMAT arcs with excessively high monitor units and long delivery time. We investigated whether an improved optimization technique would decrease the needed arc numbers and increase the delivery efficiency, while improving or maintaining the plan quality. Methods: The proposed 4pi arc space optimization algorithm consists of two steps: automatic couch angle selection followed by aperture generation for each arc with optimized control points distribution. We use a greedy algorithm to select the couch angles. Starting from a single coplanar arc plan we search through the candidate noncoplanar arcs to pick a single noncoplanar arc that will bring the best plan quality when added into the existing treatment plan. Each time, only one additional noncoplanar arc is considered making the calculation time tractable. This process repeats itself until desired number of arc is reached. The technique is first evaluated in coplanar arc delivery scheme with testing cases and then applied to noncoplanar treatments of a case with 12 brain metastasis lesions. Results: Clinically acceptable plans are created within minutes. For the coplanar testing cases the algorithm yields singlearc plans with better dose distributions than that of two-arc VMAT, simultaneously with a 12–17% reduction in the delivery time and a 14–21% reduction in MUs. For the treatment of 12 brain mets while Paddick conformity indexes of the two plans were comparable the SCG-optimization with 2 arcs (1 noncoplanar and 1 coplanar) significantly improved the conventional VMAT with 3 arcs (2 noncoplanar and 1 coplanar). Specifically V16 V10 and V5 of the brain were reduced by 11%, 11% and 12% respectively. The beam delivery time was shortened by approximately 30%. Conclusion: The proposed 4pi arc space optimization technique promises to significantly reduce the brain toxicity while greatly improving the treatment efficiency.

In the past three years nine cases of brain tumors with CSF seeding have been revealed by computed tomography (CT). We have been analyzing the CT pattern of CSF seeding, CSF cytology, and spinal metastasis. The brain tumors were classified as follows: five medulloblastomas, two glioblastomas, one germinoma, and one meningeal carcinomatosis. Their CT patterns were divided into three groups: 1) diffuse seeding of the basal cisterns. 2) invasion of the ventricular wall. 3) solitary metastasis in the ventricle. The subarachnoid seeding included four medulloblastomas and one meningeal carcinomatosis. The second type of seeding included two glioblastomas and one germinoma. One medulloblastoma had a single metastasis in the lateral ventricle. In the medulloblastomas, the diffuse seeding of the basal cisterns was more common than the invasion of the ventricular wall or solitary metastasis in the ventricle. Medulloblastomas were also accompanied by spinal metastasis. Because there were many cases of spinal metastasis in the first type of seeding, we concluded that there was a definite correlation between the CSF seeding of the basal cisterns and spinal metastasis. Needless to say, CT was the most important method for the diagnosis of the CSF seeding of brain tumors. However, because there was a case of CSF seeding which had not been demonstrated by CT, we also emphasized the importance of neurological examination and CSF cytology in the diagnosis of the CSF seeding of brain tumors.

It has been demonstrated that erlotinib is effective in treating patients with brain metastasis from non-small-cell lung cancer. However, the number of studies determining the erlotinib concentration in these patients is limited. The purpose of this study was to measure the concentration of erlotinib in the cerebrospinal fluid of patients with brain metastasis from non-small-cell lung carcinoma. Six patients were treated with the standard recommended daily dose of erlotinib (150 mg) for 4 weeks. All the patients had previously received chemotherapy, but no brain radiotherapy. At the end of the treatment period, blood plasma and cerebrospinal fluid samples were collected and the erlotinib concentration was determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The average erlotinib concentration in the blood plasma and the cerebrospinal fluid was 717.7±459.7 and 23.7±13.4 ng/ml, respectively. The blood-brain barrier permeation rate of erlotinib was found to be 4.4±3.2%. In patients with partial response (PR), stable disease (SD) and progressive disease (PD), the average concentrations of erlotinib in the cerebrospinal fluid were 35.5±19.0, 19.1±8.7 and 16.4±5.9 ng/ml, respectively. In addition, the efficacy rate of erlotinib for metastatic brain lesions was 33.3%, increasing to 50% in patients with EGFR mutations. However, erlotinib appeared to be ineffective in cases with wild-type EGFR. In conclusion, a relatively high concentration of erlotinib was detected in the cerebrospinal fluid of patients with brain metastases from non-small-cell lung cancer. Thus, erlotinib may be considered as a treatment option for this patient population. PMID:24649318

Brain metastasis of small cell lung carcinoma. Comparison of Gd-DTPA enhanced magnetic resonance imaging and enhanced computerized tomography

Small cell carcinoma of the lung (SCLC) frequently metastasizes into the brain, resulting in serious influences upon prognosis. Delayed brain damage caused by prophylactic cranial irradiation (PCI) is also problematic. Gadolinium diethylene triamine pentaacetic acid (Gd-DTPA) enhanced magnetic resonance imaging (MRI) was performed to detect early brain metastasis from SCLC, and its usefulness was compared with contrast computerized tomography (CT). Among 25 SCLC patients, brain metastasis was detected in 11 by MRI and in 10 by CT, although six of them were completely asymptomatic. In the 11 patients, 6.3 and 2.4 lesions were respectively detected on average by MRI and CT. The ability of MRI to detect metastatic lesions of ≥15 mm diameter did not differ from that of CT, but became different as lesions became smaller (P<0.002), and MRI had a decided advantage over CT because as many as 30 lesions of ≤5 mm diameter were detected by MRI, whereas such lesions visualized on CT numbered only one (P<0.0001). MRI was incomparably superior to CT (P<0.0004) for subtentorial lesions since 18 lesions were detected on MRI, but only three, measuring ≥25 mm in diameter, were demonstrated on CT. Gd-DTPA enhanced MRI was determined to be extremely useful in the early diagnosis of SCLC brain metastasis. MRI was thought to reduce delayed brain damage caused by PCI if performed according to an adequate schedule. (author)

Tumors metastasizing from distant regions to the oral and maxillofacial region are uncommon, comprising only 1%-2% of all malignancies. Cholangiocarcinoma is a malignancy that arises from cholangiocytes, which are epithelial cells that line the bile ducts. These cancers are difficult to diagnose and have a poor prognosis. In this paper, we report a rare case of mandibular metastasis of cholangiocarcinoma diagnosed at the primary site and discuss the radiographic findings observed in this case.

Identification and analysis of signaling networks potentially involved in breast carcinoma metastasis to the brain.

Directory of Open Access Journals (Sweden)

Feng Li

Full Text Available Brain is a common site of breast cancer metastasis associated with significant neurologic morbidity, decreased quality of life, and greatly shortened survival. However, the molecular and cellular mechanisms underpinning brain colonization by breast carcinoma cells are poorly understood. Here, we used 2D-DIGE (Difference in Gel Electrophoresis proteomic analysis followed by LC-tandem mass spectrometry to identify the proteins differentially expressed in brain-targeting breast carcinoma cells (MB231-Br compared with parental MDA-MB-231 cell line. Between the two cell lines, we identified 12 proteins consistently exhibiting greater than 2-fold (p<0.05 difference in expression, which were associated by the Ingenuity Pathway Analysis (IPA with two major signaling networks involving TNFα/TGFβ-, NFκB-, HSP-70-, TP53-, and IFNγ-associated pathways. Remarkably, highly related networks were revealed by the IPA analysis of a list of 19 brain-metastasis-associated proteins identified recently by the group of Dr. A. Sierra using MDA-MB-435-based experimental system (Martin et al., J Proteome Res 2008 7:908-20, or a 17-gene classifier associated with breast cancer brain relapse reported by the group of Dr. J. Massague based on a microarray analysis of clinically annotated breast tumors from 368 patients (Bos et al., Nature 2009 459: 1005-9. These findings, showing that different experimental systems and approaches (2D-DIGE proteomics used on brain targeting cell lines or gene expression analysis of patient samples with documented brain relapse yield highly related signaling networks, suggest strongly that these signaling networks could be essential for a successful colonization of the brain by metastatic breast carcinoma cells.

We present to our knowledge the first patient with histopathologically proven brain metastasis from extramammary Paget's disease (EMPD) and discuss the effect of brain radiation therapy for this condition. A 68-year-old man presented to our hospital with headache and gait disturbance. Brain MRI showed multiple enhancing mass lesions, and two large cystic lesions in the left cerebellum. The patient had been diagnosed with scrotal Paget's disease 3 months previously but no further management had been performed due to his refusal. The patient underwent stereotactic aspiration and biopsy of the two large cystic lesions. A histopathological examination revealed that the tumor was a metastatic adenocarcinoma. Immunohistochemical staining revealed that the tumor cells were strongly positive for cytokeratin 7 and moderately positive for carcinoembryonic antigen and gross cystic disease fluid protein 15. These findings were similar to those of his scrotal skin lesions and were consistent with metastatic EMPD. The patient underwent brain radiation therapy with a total radiation dose of 30 Gy in 10 fractions. The patient improved neurologically so as to be self-ambulatory, and a mild improvement in the metastatic tumors was found on follow-up MRI. We had planned systemic chemotherapy, but the patient died of acute respiratory failure 2 months after radiation therapy. Copyright © 2013 Elsevier Ltd. All rights reserved.

Full Text Available Abstract Introduction We present a case of nonseminomatous germ cell tumor of the testes with acute urinary retention secondary to urethral metastasis. This presentation, and similar cases of urethral metastasis from this tumor, have not been reported previously. Case presentation A 35-year-old Caucasian man presented to hospital with a history of acute urinary retention. On examination he was found to have right testicular enlargement with raised β-human chorionic gonadotrophin, serum α-fetoprotein and lactate dehydrogenase levels. He underwent radical left inguinal orchidectomy and histology confirmed a nonseminomatous germ cell tumor of the testes. Cystoscopy carried out due to urinary retention showed penile metastasis and the biopsy confirmed metastatic malignant undifferentiated teratoma. Staging computed tomography scan and magnetic resonance imaging of the pelvis showed pulmonary, pelvic nodal, ischial and penile metastasis. The diagnosis of the International Germ Cell Cancer Collaborative Group of poor prognosis metastatic nonseminomatous germ cell tumor was made, following which he received four cycles of bleomycin, etoposide and cisplatin chemotherapy with curative intent. He had a complete marker and an excellent radiological response. He is currently under follow up. Conclusion The unusual presentation of lymphovascular spread in this case of nonseminomatous germ cell tumor highlights the need to include routine pelvic imaging in the assessment and follow up of testicular cancer.

Intramedullary spinal cord metastasis from colonic carcinoma presenting as Brown-Sequard syndrome: a case report

LENUS (Irish Health Repository)

Kaballo, Mohammed A

2011-08-02

Abstract Introduction Intramedullary spinal cord metastasis is very rare. The majority are discovered incidentally during autopsy. Most symptomatic patients present with rapidly progressive neurological deficits and require immediate examination. Few patients demonstrate features of Brown-Séquard syndrome. Radiotherapy is the gold-standard of therapy for Intramedullary spinal cord metastasis. The overall prognosis is poor and the mortality rate is very high. We present what is, to the best of our knowledge, the first case of Intramedullary spinal cord metastasis of colorectal carcinoma presenting as Brown-Séquard syndrome. Case presentation We present the case of a 71-year-old Caucasian man with colonic adenocarcinoma who developed Intramedullary spinal cord metastasis and showed features of Brown-Séquard syndrome, which is an uncommon presentation of Intramedullary spinal cord metastasis. Conclusion This patient had an Intramedullary spinal cord metastasis, a rare form of metastatic disease, secondary to colonic carcinoma. The metastasis manifested clinically as Brown-Séquard syndrome, itself a very uncommon condition. This syndrome is rarely caused by intramedullary tumors. This unique case has particular interest in medicine, especially for the specialties of medical, surgical and radiation oncology. We hope that it will add more information to the literature about these entities.

Spinal metastasis of medulloblastoma in adults: A case report

Directory of Open Access Journals (Sweden)

Živković Nenad

2014-01-01

Full Text Available Introduction. Medulloblastoma is a primitive neuro-ectodermal malignant tumor most commonly seen in childhood and rarely and uncommonly in adult age. Treatment consists of surgery followed by radiotherapy. In the case of a relapse there is no overall accepted treatment. Tumor metastasis can be seen along the neural axis, lymph nodes, soft tissues, bones and distant organs. Case Outline. In this paper we present a 45-year-old female patient with a thoraco-spinal extramedullary metastatic medulloblastoma and progressive neurological deterioration seen 11 months after the first operation and description of magnetic resonance and intraoperative finding. Conclusion. Although rare, the presence of metastasis is a poor prognostic factor. The treatment options for patients with metastases are limited and their prognosis continues to remain poor.

Skeletal muscle metastasis is a relatively rare finding in the setting of mucinous adenocarcinoma of the colon, and it typically exhibits nonspecific imaging findings. We report a case of a skeletal muscle metastasis originating from mucinous adenocarcinoma of the cecum. The skeletal lesion closely resembled intramuscular myxoma with regard to imaging findings, due to abundant mucin and internal calcification

To evaluate local control and adverse effects after postoperative hypofractionated stereotactic radiosurgery in patients with brain metastasis. We reviewed patients who had hypofractionated stereotactic radiosurgery (7.7Gy×3 prescribed to the 70% isodose line, with 2mm planning target volume margin) following resection from March 2008 to January 2014. The primary endpoint was local failure defined as recurrence within the surgical cavity. Secondary endpoints were distant failure rates and the occurrence of radionecrosis. Out of 95 patients, 39.2% had metastatic lesions from a non-small cell lung cancer primary tumour. The median Graded Prognostic Assessment score was 3 (48% of patients). One-year local control rates were 84%. Factors associated with improved local control were no cavity enhancement on pre-radiation MRI (P<0.00001), planning target volume less than 12cm 3 (P=0.005), Graded Prognostic Assessment score 2 or above (P=0.009). One-year distant cerebral control rates were 56%. Thirty-three percent of patients received whole brain radiation therapy. Histologically proven radionecrosis of brain tissue occurred in 7.2% of cases. The size of the preoperative lesion and the volume of healthy brain tissue receiving 21Gy (V 21 ) were both predictive of the incidence of radionecrosis (P=0.010 and 0.036, respectively). Adjuvant hypofractionated stereotactic radiosurgery to the postoperative cavity in patients with brain metastases results in excellent local control in selected patients, helps delay the use of whole brain radiation, and is associated with a relatively low risk of radionecrosis.

2013-01-01

Full Text Available Lung cancer represents the leading cause of cancer-related mortality throughout the world. Patients die of local progression, disseminated disease, or both. At least one third of the people with lung cancer develop brain metastases at some point during their disease, even often before the diagnosis of lung cancer is made. The high rate of brain metastasis makes lung cancer the most common type of tumor to spread to the brain. It is critical to understand the biologic basis of brain metastases to develop novel diagnostic and therapeutic approaches. This review will focus on the emerging data supporting the involvement of the chemokine CXCL12 and its receptor CXCR4 in the brain metastatic evolution of non-small-cell lung cancer (NSCLC and the pharmacological tools that may be used to interfere with this signaling axis.

Start with two cases of brain metastases from lung melanoma are presented who were diagnosed in the Neuropathology Laboratory of the Department of Anatomy Pathology, Institute of Neurology, Hospital de Clinicas, Montevideo, emphasizing the pathological diagnostic criteria and their evolution clinic. Both patients presented at the time of the initial consultation injuries amelánica respectively pigmented single brain. In both cases ruled by the morphology and the use of complementary techniques metastasis carcinoma. The main differential diagnosis of these lesions is whether is a primitive brain tumor, pigmented or not, or of a secondary tumor melanin: metastatic malignant melanoma. In both cases the patients had been studied one being in an unresectable lung injury, and in the other showed a single pulmonary nodule was resected in its entirety. the pulmonary lesions were for malignant melanoma, one with ample pigment and the other for the most part amelánico, with few areas retained pigment. He studied dermatologist, discarded the presence of a cutaneous malignant melanoma primitive. Other locations were also excluded

Purpose: To evaluate the prevalence, outcomes, and toxicities of concurrent delivery of systemic therapy with stereotactic radiosurgery (SRS) for treatment of brain metastases. Methods and Materials: We conducted a retrospective review of 193 patients treated at our institution with SRS without prior whole-brain radiation therapy (WBRT) for brain metastases between 2009 and 2014. Outcome metrics included administration of concurrent systemic therapy, myelosuppression, neurotoxicity, and survival. Results: One hundred ninety-three patients with a median age of 61 years underwent a total of 291 SRS treatments. Thirty-seven percent of SRS treatments were delivered concurrently with systemic therapy, of which 46% were with conventional myelosuppressive chemotherapy, and 54% with targeted and immune therapy agents. Myelosuppression was minimal after treatment with both systemic therapy and SRS, with 14% grade 3-4 toxicity for lymphopenia and 4-9% for leukopenia, neutropenia, anemia, and thrombocytopenia. Neurotoxicity was also minimal after combined therapy, with no grade 4 and <5% grade 3 toxicity, 34% dexamethasone requirement, and 4% radiation necrosis, all similar to treatments with SRS alone. Median overall survival was similar after SRS alone (14.4 months) versus SRS with systemic therapy (12.9 months). In patients with a new diagnosis of primary cancer with brain metastasis, early treatment with concurrent systemic therapy and SRS correlated with improved survival versus SRS alone (41.6 vs 21.5 months, P<.05). Conclusions: Systemic therapy can be safely given concurrently with SRS for brain metastases: our results suggest minimal myelosuppression and neurotoxicity. Concurrent therapy is an attractive option for patients who have both intracranial and extracranial metastatic disease and may be particularly beneficial in patients with a new diagnosis of primary cancer with brain metastasis.

Hebbar, Ashwin K; Shashidhar, K; S, Krishna Murthy; Kumar, Veerendra; Arjunan, Ravi

2014-09-01

Background and objectives Metastasis to the breast from extra mammary sites is uncommon with an incidence ranging from 1.2 to 2 % in clinical reports. Approximately 300 cases of breast metastasis from extra mammary sites have been reported, mostly in small series or as a single case report. Gastrointestinal adenocarcinoma metastasising to the breast is also very rare and only 30 cases have been reported in the literature. Metastatic deposits within the breast may be difficult to distinguish from primary breast carcinoma. Radiological features and immunohistochemistry especially for steroid hormone receptors (ER/PR) and expression of gross cystic disease fluid protein (GCDFP) and presence of other immunohistochemistry protein factors in breast metastasis which are specific to primary site may be helpful in differentiating these two conditions. Materials and methods In this series of 3 cases of breast as an unusual site of metastasis, we present different cases of adenocarcinoma of stomach, sigmoid colon and kidney with metastasis to the breast and discuss the differential diagnosis and management plans. Conclusion In conclusion, secondary tumors to the breast are rare and thus differentiating primary tumors from metastatic breast carcinoma is important for rational and optimum therapy and avoidance of unnecessary radical surgery. Palpable breast lump without typical radiological signs of primary breast carcinoma in patients with known primary should be suspected of representing metastasis.

History and current state of immunotherapy in glioma and brain metastasis.

Malignant brain tumors such as glioblastoma (GBM) and brain metastasis have poor prognosis despite conventional therapies. Successful use of vaccines and checkpoint inhibitors in systemic malignancy has increased the hope that immune therapies could improve survival in patients with brain tumors. Manipulating the immune system to fight malignancy has a long history of both modest breakthroughs and pitfalls that should be considered when applying the current immunotherapy approaches to patients with brain tumors. Therapeutic vaccine trials for GBM date back to the mid 1900s and have taken many forms; from irradiated tumor lysate to cell transfer therapies and peptide vaccines. These therapies were generally well tolerated without significant autoimmune toxicity, however also did not demonstrate significant clinical benefit. In contrast, the newer checkpoint inhibitors have demonstrated durable benefit in some metastatic malignancies, accompanied by significant autoimmune toxicity. While this toxicity was not unexpected, it exceeded what was predicted from pre-clinical studies and in many ways was similar to the prior trials of immunostimulants. This review will discuss the history of these studies and demonstrate that the future use of immune therapy for brain tumors will likely need a personalized approach that balances autoimmune toxicity with the opportunity for significant survival benefit.

A solitary tuberculous brain lesion (STBL) can be difficult to distinguish from a glioma, metastasis or other infectious disease, especially from a pyogenic brain abscess. We analyzed the clinical characteristics, diagnostic procedures and outcomes of 24 patients with STBL diagnosed in three centers from France, India and Mexico. We also reviewed 92 STBL cases previously reported in the literature. General symptoms were found in 54% of our patients, including enlarged lymph nodes in 20%. Cerebrospinal fluid was typically abnormal, with lymphocytic pleocytosis and a high protein level. The lung CT scan was abnormal in 56% of patients, showing lymphadenopathy or pachipleuritis. Brain MRI or CT was always abnormal, showing contrast-enhanced lesions. Typically, MRI abnormalities were hypointense on T1-weighted sequences, while T2-weighted sequences showed both a peripheral hypersignal and a central hyposignal. The diagnosis was documented microbiologically or supported histologically in 71% of cases. Clinical outcome was good in 83% of cases. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

1996-01-01

PURPOSE/OBJECTIVE: To assess quality of life effects of radiation therapy on patients with brain metastasis. Not only is data on this subject rare, there is also no psychometrically tested brain metastasis symptom scale. We report data using a scale of our own design. MATERIALS and METHODS: Over 200 charts of patients treated for brain metastasis from various primary sites between 1990 and 1995 were reviewed. Seventy-two patients met the criteria for evaluation. They were all treated with radiotherapy and steroids. The majority of patients received a median dose of 30 Gy (Range 20 - 55) to the whole brain. Treatment over 40 Gy was delivered via a boost, either external beam or stereotactic. Pre and post-therapy symptoms of impaired vision, speech, sensation, motor strength, gait, cranial nerves, headache, seizure, lethargy, mentation, and nausea and vomiting were scored. Each symptom was evaluated separately. Following therapy, patients were noted to have improvement, no change, or worsening symptoms. Steroid and anti-seizure medication use pre and post-therapy were also recorded. RESULTS: Patient characteristics: median age is 62 (Range 27 - 82 years); Female: Male 1.4:1; Single: Multiple metastasis = 1:2.3. The primary sites included: lung=56%, breast=15%, unknown=11%, and various=18%. The histologies included: adenocarcinoma=26%, squamous cell carcinoma=21%, small cell carcinoma=15%, infiltrating ductal=14%, and various=24%. All patients had a minimum of one month post-treatment follow up (Range 1 - 24 mths). Sixteen patients are still living. Eighty-nine percent were symptomatic at presentation and 36% presented with only one symptom. The incidence of symptoms before treatment was: altered mentation=26%, decreased motor strength=26%, headache=24%, seizure=21%, altered gait=20%, nausea/vomiting=18%, speech deficit=15%, lethargy=11%, visual change=8%, altered sensation=7%, and cranial nerve deficits=3%. A statistically significant improvement in mentation (p<0

Isolated Splenic Metastasis from Renal Cell Carcinoma: Case Report and Review

Directory of Open Access Journals (Sweden)

J.A.G. Moir

2011-04-01

Full Text Available This report presents the case of a 70-year-old woman with a previous history of a left nephrectomy for renal cell carcinoma (RCC, who developed general malaise and fatigue. Abdominal computed tomography demonstrated an enhancing 6 × 7 cm necrotic lesion in the lower pole of the spleen suggestive of a metastasis. Given the highly suspicious nature of the lesion we proceeded to splenectomy. The tumour did not breach the splenic capsule, and there was no local diaphragmatic involvement. The mass was concluded to be a true metastasis of the original RCC rather than local recurrence of the disease. The causes of isolated solid splenic lesions are wide and varied, however a past or present history of malignancy should lead to a high index of suspicion for a splenic metastasis. We report an extremely unusual case of spread from a RCC.

Radiosurgery without whole brain radiotherapy in melanoma brain metastases

1998-01-01

To evaluate the effectiveness of radiosurgery without whole brain radiotherapy in the palliative treatment of melanoma brain metastases, we retrospectively assessed the results in 35 patients: 4 with a solitary brain metastasis, 13 with a single brain metastasis and metastases elsewhere and 18 with multiple brain metastases. The local control rate was 98.2% (55/56 metastases) at 3 months. Median survival was 22 months in patients with a solitary brain metastasis, 7.5 months in patients with a single brain metastasis and metastases elsewhere, and 4 months in patients with multiple brain metastases. Complications were unusual and surgery was required in 2 of 35 patients. These results show for the first time that melanoma patients with a unique brain metastasis with or without metastases elsewhere clearly benefit from tumour control easily obtained by radiosurgery. Although the comparison of radiosurgery with surgery and/or whole brain radiotherapy cannot be adequately addressed, radiosurgery alone seems to provide similar results with lower morbidity and impact on quality of life.

2017-07-01

We investigated the potential of textural feature analysis of O-(2-[ 18 F]fluoroethyl)-L-tyrosine ( 18 F-FET) PET to differentiate radiation injury from brain metastasis recurrence. Forty-seven patients with contrast-enhancing brain lesions (n = 54) on MRI after radiotherapy of brain metastases underwent dynamic 18 F-FET PET. Tumour-to-brain ratios (TBRs) of 18 F-FET uptake and 62 textural parameters were determined on summed images 20-40 min post-injection. Tracer uptake kinetics, i.e., time-to-peak (TTP) and patterns of time-activity curves (TAC) were evaluated on dynamic PET data from 0-50 min post-injection. Diagnostic accuracy of investigated parameters and combinations thereof to discriminate between brain metastasis recurrence and radiation injury was compared. Diagnostic accuracy increased from 81 % for TBR mean alone to 85 % when combined with the textural parameter Coarseness or Short-zone emphasis. The accuracy of TBR max alone was 83 % and increased to 85 % after combination with the textural parameters Coarseness, Short-zone emphasis, or Correlation. Analysis of TACs resulted in an accuracy of 70 % for kinetic pattern alone and increased to 83 % when combined with TBR max . Textural feature analysis in combination with TBRs may have the potential to increase diagnostic accuracy for discrimination between brain metastasis recurrence and radiation injury, without the need for dynamic 18 F-FET PET scans. • Textural feature analysis provides quantitative information about tumour heterogeneity • Textural features help improve discrimination between brain metastasis recurrence and radiation injury • Textural features might be helpful to further understand tumour heterogeneity • Analysis does not require a more time consuming dynamic PET acquisition.

Forty-one patients suffered initial relapses with brain metastasis after surgery for non-small lung cancer at our hospital between 1978 and 1995. These patients were a total of 8.4% of all cases of surgical removal, and had an average relapse period of 8.6 months ± 8.0 months after surgery on the primary lesions. Of these, surgical removal of metastasized lesions was performed on 18 patients (43%), in which the 5-year post-operative survival rate was 35.7%, and the median survival time was good at 28 months. It was found that the survival period was significantly extended in the group whose relapse period was less than one year after surgery on the primary lesions, and in the group who received cranial irradiation post-operatively on the metastasized brain lesion. Following surgery on the metastasized lesion, second relapses occurred in nine patients, and six patients suffered from second relapses in the brain, of which four did not receive cranial irradiation post-operatively. Cases of radiotherapy in patients of 70 years of age or more frequently manifested post-radiotherapy subacute neuropathy. From the above, it is thought that the following procedures should be adopted: Periodic examination for brain metastasis during the 24 months following surgery for non-small cell lung carcinoma for purposes of early detection; in cases where brain metastasis is detected, if no metastasis is identified in other organs, a policy of surgical removal should be adopted where possible; and, in cases of 70 years of age or less following surgery on the metastasized lesion, cranial irradiation should be considered.

2011-01-01

The spleen in rarely the place for solid, non-haematological tumors, isolated splenic metastases from adenocarcinomas being extremely rare findings, regardless of the origin and the histological type of the primary tumor. We present the case of a female patient with isolated splenic metastasis diagnosed by abdominal computer tomography at only 20 months after curative surgery for endometrial adenocarcinoma, in which the final diagnosis has been established by histological and immunohistochemical examination of the splenectomy piece. The haematogenous dissemination of the endometrial cancer occurs most commonly in the lungs, liver or bones, the spleen being rarely affected. In the medical literature there are cited up to date only 12 cases of solitary splenic metastasis from endometrial adenocarcinoma. The particularity of the case presented by us is the early appearance of an isolated splenic metastasis, at less than two years after curative surgery (compared to an average of 4-5 years cited in the literature), from an endometrial cancer which was classified histologicaly in the group with low-risk for relapse (well differentiated endometrioid adenocarcinoma). In conclusion, although solitary splenic secondary determinations are very rare, the incidence of the reported cases in the medical literature is increasing, their late appearance (a few years after the primary tumor's resection) and the lack of symptoms until the tumor reaches appreciable size or it complicates with necrosis, justifies the periodic abdominal imaging examination, on long-term, for postoperative monitorisation after the initial curative surgery. Their treatment of choice is open, classical splenectomy that must be followed by chemotherapy in order to prevent the development of other possible micrometastases.

Skull metastasis revealing a renal tumor: A case report and review of the literature

Directory of Open Access Journals (Sweden)

Mohamed Badri

Full Text Available Background: Renal cell carcinomas represent 85% of malignant renal tumors. Typically, the tumor remains asymptomatic a long time before the appearance of urologic clinical signs. In some cases, metastasis can precede the manifestations of the primary tumor. Different sites are potential metastatic localizations for renal tumors, including skull metastases who represent a very rare location. Case description: We report the case of a 65-year-old man presented after the appearance of a skull mass. This tumefaction developed and had progressively grown up during 9 months. Neurological examination was normal. Brain imaging showed a soft tissue lesion in the left parietal bone with marked osteolysis. Peroperative was found a huge oval-shape hemorrhagic and firm mass associated with scalp invasion and bone destruction that was totally resected. Histopathology revealed renal cell carcinoma (RCC. Pelvic and abdominal CT scan was performed, revealing a large mass on the left kidney with irregular contours and poor definition. The patient was then transferred to urology where he underwent nephrectomy. The patient went then through adjuvant chemotherapy. Clinical and radiological follow up of 12 months did not bring to light tumor recurrence. Conclusions: Although metastases to the head and neck occur infrequently, they should be considered when evaluating any unusual subcutaneous mass in the head and neck. RCC should not be discounted when sites as unlikely as the calvaria are evaluated. Treatment of metastatic renal cell carcinoma is complex, and the optimal regimen for achieving a lasting response without severe toxicity has not yet been defined.

Cancer associated fibroblasts (CAFs) which shape the tumor microenvironment (TME) and the presence of blood brain barrier (BBB) remain great challenges in targeting breast cancer and its brain metastasis. Herein, we reported a strategy using PTX-loaded liposome co-modified with acid-cleavable folic acid (FA) and BBB transmigrating cell penetrating peptide dNP2 peptide (cFd-Lip/PTX) for enhanced delivery to orthotopic breast cancer and its brain metastasis. Compared with single ligand or non-cleavable Fd modified liposomes, cFd-Lip exhibited synergistic TME targeting and BBB transmigration. Moreover, upon arrival at the TME, the acid-cleavable cFd-Lip/PTX showed sensitive cleavage of FA, which reduced the hindrance effect and maximized the function of both FA and dNP2 peptide. Consequently, efficient targeting of folate receptor (FR)-positive tumor cells and FR-negative CAFs was achieved, leading to enhanced anti-tumor activity. This strategy provides a feasible approach to the cascade targeting of TME and BBB transmigration in orthotopic and metastatic cancer treatment. Copyright © 2018. Published by Elsevier Inc.

Lung cancer is the leading cause of cancer-related death in men and women. It is also the most common cause of brain metastases. A brain metastasis model is difficult to be established because of the presence of the blood-brain barrier (BBB) and the lack of optimal methods for detecting brain metastasis in nude mice. Thus, the establishment of a Chinese lung adenocarcinoma cell line and its animal model with brain metastasis potency and in vivo research is of great significance. CPA-Yang1 cells were obtained from a patient with human lung adenocarcinoma by lentiviral vector-mediated transfection of green fluorescence protein. Intracardiac inoculation of the cells was performed in nude mice, and brain metastatic lesions were detected using micro ¹⁸F FDG-PET/CT scanners, small animal in vivo imaging system for fluorescence, radionuclide and X ray fused imaging, magnetic resonance imaging (MRI) with sense body detection, and resection. The samples were divided into two parts for cell culture and histological diagnosis. The process was repeated in vivo and in vitro for four cycles to obtain a novel cell clone, CPA-Yang1-BR. A novel cell clone, CPA-Yang1-BR, was obtained with a brain metastatic rate of 50%. The use of MRI for the detection of brain metastases has obvious advantages. An experimental Chinese lung adenocarcinoma cell clone (CPA-Yang1-BR) and its animal model with brain metastasis potency in nude mice were established. MRI with sense body or micro MRI may be used as a sensitive, accurate, and noninvasive method to detect experimental brain metastases in intact live immunodeficient mice. The results of this study may serve as a technical platform for brain metastases from lung adenocarcinoma.

Ever since Stephen Paget's 1889 hypothesis, metastatic organotropism has remained one of cancer's greatest mysteries. Here we demonstrate that exosomes from mouse and human lung-, liver- and brain-tropic tumour cells fuse preferentially with resident cells at their predicted destination, namely lung fibroblasts and epithelial cells, liver Kupffer cells and brain endothelial cells. We show that tumour-derived exosomes uptaken by organ-specific cells prepare the pre-metastatic niche. Treatment with exosomes from lung-tropic models redirected the metastasis of bone-tropic tumour cells. Exosome proteomics revealed distinct integrin expression patterns, in which the exosomal integrins α6β4 and α6β1 were associated with lung metastasis, while exosomal integrin αvβ5 was linked to liver metastasis. Targeting the integrins α6β4 and αvβ5 decreased exosome uptake, as well as lung and liver metastasis, respectively. We demonstrate that exosome integrin uptake by resident cells activates Src phosphorylation and pro-inflammatory S100 gene expression. Finally, our clinical data indicate that exosomal integrins could be used to predict organ-specific metastasis.

Purpose: Single-isocenter (SI) volumetric modulated arc therapy has been shown to be an effective and efficient approach to multiple metastasis radiosurgery. However, certain extreme cases raise the question of whether multiple-isocenter (MI) approaches can still generate superior plans. In this study, we ask this question with respect to a clinical case with two very widely separated lesions. Methods: A patient with two widely separated (d = 12cm) tumors was treated with SI-VMAT SRS using 10MV flattening filter free (FFF) beam with high-definition multi-leaf collimator (HD-MLC, 2.5/5mm) in two non-coplanar arcs using concentric rings to enforce steep gradient. Because of lesion positioning with respect to collimator angle selection, lesions were treated by 5mm leaves. We re-planned the case with a congruent arc arrangement but separate isocenter for each lesion. In this manner, lesions were treated by 2.5mm leaves. Conformity index (CI), V50%, and mean brain dose were compared. Results: Neither conformity (CI-SI = 1.12, CI-MI = 1.08) nor V50% (V50%-SI =8.82cc, V50%-MI =8.81cc) were improved by utilizing a separate isocenter for each lesion. Mean brain dose was slightly reduced (dmean-SI = 118.4 cGy, dmean-MI = 88.7 cGy) by using multiple isocenters. Conclusion: For this case with a lesion at the apex of the brain and another distantly located at the base of skull, employing a separate isocenter for each target did not meaningfully improve plan quality. Single-isocenter VMAT has been shown feasible and equivalent to multiple-isocenter VMAT for multiple metastasis cases in general. In this extreme case, single- and multiple- isocenter VMAT were also equivalent. If rotational setup errors are appropriately corrected, the increased delivery efficiency of the single-isocenter approach renders it preferable to the multiple isocenter approach.

2012-01-01

Full Text Available Endotracheal metastasis is a rare situation, usually associated with malignancies of breast and gastrointestinal tract, specially colon. Papillary carcinoma of thyroid commonly disseminates through lymphatic channels and tracheal involvement through vascular route is rarely reported. Here, we report a case of tracheal metastasis from papillary carcinoma of thyroid. The patient responded to external beam radiation therapy with cobalt 60 beams in a dose of 44 Gy followed by a 16 Gy boost. The patient is under followup and is presently asymptomatic. This paper adds to the repertoire of evidence in treatment of endotracheal metastasis.

2018-07-01

A 19-year-old man suffering from testicular choriocarcinoma presented to the dermatology department with a cutaneous metastasis on his head. This metastasis was the first sign of disease that led to medical consultation. Histopathology revealed cytotrophoblasts and syncytiotrophoblasts, the later expressing human chorionic gonadotropin antigen. Whole body computed tomography showed multiple metastases of the brain, lung, liver, bone, paraaortic lymph nodes and left uvea; the primary was found in the left testicle. Despite neurosurgical intervention and chemotherapy the patient died 9 days after the biopsy of the cutaneous metastasis. Cutaneous metastases of testicular choriocarcinoma are exceptionally rare, with fewer than a dozen cases reported in the English-language literature. The present case highlights that testicular choriocarcinoma metastatic to the skin should be included in the differential of cutaneous scalp tumors. © 2018 John Wiley & Sons A/S.

Full Text Available Metastasis occurs with 50% of lung carcinomas, most commonly to lymph nodes, adrenal glands, liver, bone, and brain. It is extremely rare for lung cancer to present with symptoms of a gastrointestinal metastasis and even more so pertaining to the colon. To the best of our knowledge, only 12 such cases have been reported in the literature. We describe a case of a 71-year-old female presenting with refractory iron deficiency anemia that was found to have a lesion in the transverse colon. Pathology revealed adenocarcinoma of the lung and a subsequent lung lesion was discovered in a retrograde fashion.

Full Text Available Spinal epidural cavernomas are quite rare lesions and only 5% of all cavernomas are located in the spine. The lesions are most commonly localized in the thoracic region. The differential diagnosis includes neurogenic tumors, lymphoma, schwannoma, meningioma, multiple myeloma, Ewing's sarcoma and metastasis. A 40- year-old male patient presented with paraplegia and MR images revealed an epidural soft tissue constricting the right posterolateral of the cord at the T6 level. Pathology showed cavernous hemangioma. A literature search revealed no other case that so closely mimicked metastasis by invading all components of the thoracic vertebra and also expanding to the epidural distance. We therefore present the case emphasizing these features.

Thyroid Gland Metastasis from Cancer of the Uterine Cervix: An Extremely Rare Case Report.

Celik, Suleyman Utku; Besli, Dilara; Sak, Serpil Dizbay; Genc, Volkan

The thyroid gland is a relatively uncommon site for a metastatic disease, although it is richly supplied with blood. The metastases may originate from various primary sites, mainly kidney, lung, head and neck, and breast. Thyroid metastasis from cervical carcinomas is extremely rare; and only a few cases have been previously reported in the literature. In patient with thyroid nodules and an oncological history, the possibility of thyroid metastasis should be seriously considered. Despite the rarity of the metastasis of cervical carcinoma to the thyroid, it is difficult to say appropriate treatment approach for these lesions. When managing such patients, decision-making should balance the possibility of gaining long-term survival against estimation of the aggressiveness of the disease and its possible complications. Here, a case of thyroid metastasis from a squamous cell carcinoma of the uterine cervix presenting with cervical mass and difficulty in swallowing and its treatment is reported.

2007-01-01

Gingival metastases are very rare. We report the case of a 47 year-old man presenting with a gingival metastasis from a non small cell lung carcinoma. According to the literature, the most probable way of spread of such metastasis is hematogenous. Local implantation of cancer cells, present in patient's expectoration, in a fragile gingival may be an other pathway of lung cancer metastasizing in this region as we will try to describe in this case report. Cytological and/or histological investigation is needed to assess the malignant and the metastatic character of these gingival lesions. A rapid regression is observed after a flash of external beam radiation; nevertheless metastasis prognosis depends on the primary tumour progress. (authors)

Full Text Available We report a case of an 8-year-old girl with metastasis of malignant melanoma (MM to the ovary. She was initially diagnosed with cutaneous MM on the left buttock for which she underwent wide local excision, left inguinal/pelvic lymph node dissection, and subcutaneous injection of interferon beta. In spite of the treatment, she developed dissemination of MM to the liver, the bone, and the right ovary. All the lesions responded well to systemic chemotherapy (intravenous dacarbazine, except for the right ovarian tumor. She underwent an elective right salpingo-oophorectomy to avoid torsion or rupture of the tumor. However, she developed metastases to the contralateral ovary with peritoneal dissemination in 4 months. She received home palliative care and died at home 14 months after the last surgery. Ovarian metastasis of MM is a rare form of dissemination, and only 15 adult cases have ever been reported. Our patient is the first pediatric case. Since there is no standard of surgical indication for metastatic MM to the ovary, palliative resection can be an option for improving quality of life of a patient with this rare condition.

The aims of this retrospective study were to identify clinical cases of dogs with appendicular osteosarcoma (OSA) in which hepatic metastasis was confirmed, to highlight the use of cytology for its diagnosis and to describe the radiographic and ultrasonographic appearances of the lesion. Medical records were retrospectively reviewed for dogs with appendicular OSA and hepatic metastases between January 2005 and January 2013. Reviews of radiographs, ultrasounds and cytology were performed. Six dogs with appendicular OSA and hepatic metastases were identified. The ultrasonographic appearance of metastatic lesions varied, including hyperechoic with shadowing, hyperechoic without shadowing, hypoechoic and mixed echogenicity. In two cases, the hepatic metastases were also evident on thoracic radiographs. The mean survival time from diagnosis of appendicular OSA was 188 days (range 69-363 days) and from diagnosis of hepatic metastases was 35 days (range 2-69 days). Death was tumour-related in all cases. Hepatic metastasis varies widely in its ultrasonographic appearance. In three of six cases, hepatic metastasis was identified without concurrent pulmonary metastasis; therefore, abdominal ultrasound may be useful at regular intervals for patient evaluation, especially in clinical trials where accurate identification of the disease-free interval is crucial. Once hepatic metastasis is confirmed, survival times appear limited. © 2016 Australian Veterinary Association.

The metastasis of malignant tumors to the spleen is rare, and only a small percentage of cases can be treated surgically, as splenic metastases generally occur in the context of multivisceral metastatic cancer at a terminal stage. We report a rare case of metachronous solitary splenic metastasis arising from early gastric cancer. A 75-year-old man was initially referred to our hospital for examination of gastric cancer, diagnosed at a medical check-up. Esophagogastroduodenoscopy showed a slightly elevated lesion with a central irregular depression in the upper-third of the stomach. Biopsy specimens of the lesion showed a moderately-differentiated adenocarcinoma, and abdominal computed tomography showed no evidence of distant metastases. Endoscopic submucosal dissection was performed, with histological confirmation of a moderately-differentiated adenocarcinoma invading the submucosal layer. The patient subsequently underwent laparoscopic total gastrectomy with regional lymph node dissection, resulting in no residual carcinoma and no lymph node metastasis. Computed tomography, 28 months later, showed a well-defined mass measuring 4.2 cm in diameter in the spleen, and the patient underwent a splenectomy, since there was no evidence of further metastatic lesions in any other organs. Histological examination confirmed the diagnosis of a poorly-differentiated adenocarcinoma originating from the previous gastric cancer. The patient was alive 2 months after surgical resection of the splenic metastasis without any recurrence. To the best of our knowledge, this is only the second case of a solitary splenic metastasis from early gastric cancer to be reported in the English literature. The present case suggests surgical resection may be the preferred treatment of choice for patients with a solitary splenic metastasis from gastric cancer.

Balaban, Mehtap; Dogruyol, Sureyya Vudali; Idilman, Ilkay S.; Unal, Ozlem; Ipek, Ali

2016-01-01

Renal cell carcinoma (RCC) – also known as hypernephroma or grawitz tumor – accounts for 3% of the adulthood malignancies. Approximately 30–40% of the patients have metastasis at the time of the diagnosis and most common sites for metastasis are lung, regional lymph nodes, bone and liver. A total of 8–14% of the patients with RCC has head and neck metastasis. However, metastasis to major salivary glands is rarely seen. In this paper, we aimed to report a RCC case with metastasis to parotid and submandibular glands that has the same sonographic and sonoelastographic findings with the primary tumor. 66-year old woman with RCC history was referred to our radiology department for neck ultrasound (US) with painful swelling in the right parotid gland region. A well-defined, 37×21 mm sized hypoechoic heterogeneous solid mass was detected in the superficial-deep lobe of the right parotid gland. The mass was prominently hypervascular in color Doppler ultrasonography scan. Coincidentally, a 13×13 mm hypoechoic lobulated solid mass was detected in the right submandibular gland with similar sonographic findings. Real-time sonoelastography (SEL) was performed to the masses and both of them were blue-green colored that indicates hard tissue. An US and SEL evaluation was also performed to the renal mass (RCC) of the patient. The primary mass was also similar in sonographic and SEL appearance as salivary gland masses. In the patient history, she revealed chemotherapy-radiotherapy treatment 1.5 years ago due to inoperable mass in the mid-lower pole of the left kidney diagnosed as clear cell RCC with vascular invasion, liver, lung and brain metastasis. Because of known primary tumor, the masses in the salivary glands were suspected to be metastatic and a tru-cut biopsy was performed. Pathological result was reported as clear cell RCC metastasis. The etiology of RCC is still unknown and metastatic involvement can be seen at unexpected tissue and organs. Metastatic disease

Conventional MRI is the standard method to diagnose recurrence of brain metastases after radiation. However, following radiation therapy, reactive transient blood-brain barrier alterations with consecutive contrast enhancement can mimic brain metastasis recurrence. Recent studies have suggested that O-(2-18F-fluoroethyl)-L-tyrosine (FET) PET improves the correct differentiation of brain metastasis recurrence from radiation injury. Based on published evidence and clinical expert opinion, we analyzed effectiveness and cost-effectiveness of the use of FET PET in addition to MRI compared with MRI alone for the diagnosis of recurrent brain metastases. A decision-tree model was designed to compare the 2 diagnostic strategies from the perspective of the German Statutory Health Insurance (SHI) system. Effectiveness was defined as correct diagnosis of recurrent brain metastasis and was compared between FET PET with MRI and MRI alone. Costs were calculated for a baseline scenario and for a more expensive scenario. Robustness of the results was tested using sensitivity analyses. Compared with MRI alone, FET PET in combination with MRI increases the rate of correct diagnoses by 42% (number needed to diagnose of 3) with an incremental cost-effectiveness ratio of €2821 (baseline scenario) and €4014 (more expensive scenario) per correct diagnosis. The sensitivity analyses confirmed the robustness of the results. The model suggests that the additional use of FET PET with conventional MRI for the diagnosis of recurrent brain metastases may be cost-effective. Integration of FET PET has the potential to avoid overtreatment with corresponding costs as well as unnecessary side effects. © The Author(s) 2017.

Full Text Available Objective: To evaluate the additional diagnostic value of diffusion and perfusion MRI in the differentiation of glioblastoma multiforme (GBM and solitary brain metastasis. Patients and methods: This retrospective study included 24 patients with histologically proven brain tumors who underwent conventional MRI with analysis of diffusion (DWI and perfusion (PWI MRI findings of each tumor. The Apparent Diffusion Coefficient (ADC values were calculated in the minimum (ADC-MIN, mean (ADC-MEAN, and maximum (ADC-MAX in all the tumors and the peritumoral regions. The PWI data was expressed as maximum regional cerebral blood volume (rCBV of the tumors and peritumoral regions. Results: After adding diffusion and perfusion to conventional MRI findings, we found that the accuracy of differentiation between glioblastoma multiforme (GBM and solitary metastasis increased from 70% to 90%.There is a significant difference in DWI signal intensity between GBM and metastatic tumors (P < 0.05. The ADC values of GBM were lower than that of metastatic tumors. On perfusion MRI, the maximum rCBV of the peritumoral region (rCBVP of GBM was higher than that of brain metastases (P < 0.001. Conclusion: The addition of diffusion and perfusion to the MRI protocol increases the accuracy of differentiation between GBM and solitary brain metastasis and should be considered routinely.

The authors conducted validity testing of the 5 major reported indices for radiosurgically treated brain metastases- the original Radiation Therapy Oncology Group's Recursive Partitioning Analysis (RPA), the Score Index for Radiosurgery in Brain Metastases (SIR), the Basic Score for Brain Metastases (BSBM), the Graded Prognostic Assessment (GPA), and the subclassification of RPA Class II proposed by Yamamoto-in nearly 2500 cases treated with Gamma Knife surgery (GKS), focusing on the preservation of neurological function as well as the traditional endpoint of overall survival. The authors analyzed data from 2445 cases treated with GKS by the first author (T.S.), the primary surgeon. The patient group consisted of 1716 patients treated between January 1998 and March 2008 (the Chiba series) and 729 patients treated between April 2008 and December 2011 (the Tokyo series). The interval from the date of GKS until the date of the patient's death (overall survival) and impaired activities of daily living (qualitative survival) were calculated using the Kaplan-Meier method, while the absolute risk for two adjacent classes of each grading system and both hazard ratios and 95% confidence intervals were estimated using the Cox proportional hazards model. For overall survival, there were highly statistically significant differences between each two adjacent patient groups characterized by class or score (all p values RPA appeared to be better than the original RPA and GPA. The modified RPA subclassification, proposed by Yamamoto, is well balanced in scoring simplicity with respect to case number distribution and statistical results for overall survival. However, a new or revised grading system is necessary for predicting qualitative survival and for selecting the optimal treatment for patients with brain metastasis treated by GKS.

Brain metastasis in human epidermal growth factor receptor 2-positive breast cancer: from biology to treatment

Overexpression of human epidermal growth factor receptor 2 (HER2) is found in about 20% of breast cancer patients. With treatment using trastuzumab, an anti-HER2 monoclonal antibody, systemic control is improved. Nonetheless, the incidence of brain metastasis does not be improved, rather seems to be increased in HER2-positive breast cancer. The mainstay treatment for brain metastases is radiotherapy. According to the number of metastatic lesions and performance status of patients, radiosurgery or whole brain radiotherapy can be performed. The concurrent use of a radiosensitizer further improves intracranial control. Due to its large molecular weight, trastuzumab has a limited ability to cross the blood-brain barrier. However, small tyrosine kinase inhibitors such as lapatinib, has been noted to be a promising agent that can be used as a radiosensitizer to affect HER2-positive breast cancer. This review will outline general management of brain metastases and will focus on preclinical findings regarding the radiosensitizing effect of small molecule HER2 targeting agents.

To assess the effect of computer-aided detection (CAD) of brain metastasis (BM) on radiologists' diagnostic performance in interpreting three-dimensional brain magnetic resonance (MR) imaging using follow-up imaging and consensus as the reference standard. The institutional review board approved this retrospective study. The study cohort consisted of 110 consecutive patients with BM and 30 patients without BM. The training data set included MR images of 80 patients with 450 BM nodules. The test set included MR images of 30 patients with 134 BM nodules and 30 patients without BM. We developed a CAD system for BM detection using template-matching and K-means clustering algorithms for candidate detection and an artificial neural network for false-positive reduction. Four reviewers (two neuroradiologists and two radiology residents) interpreted the test set images before and after the use of CAD in a sequential manner. The sensitivity, false positive (FP) per case, and reading time were analyzed. A jackknife free-response receiver operating characteristic (JAFROC) method was used to determine the improvement in the diagnostic accuracy. The sensitivity of CAD was 87.3% with an FP per case of 302.4. CAD significantly improved the diagnostic performance of the four reviewers with a figure-of-merit (FOM) of 0.874 (without CAD) vs. 0.898 (with CAD) according to JAFROC analysis (p reviewers (FOM without vs. with CAD, 0.834 vs. 0.877, p review the CAD results was approximately 72 sec (40% of the total review time). CAD as a second reader helps radiologists improve their diagnostic performance in the detection of BM on MR imaging, particularly for less-experienced reviewers.

We investigated the potential of textural feature analysis of O-(2-[{sup 18}F]fluoroethyl)-L-tyrosine ({sup 18}F-FET) PET to differentiate radiation injury from brain metastasis recurrence. Forty-seven patients with contrast-enhancing brain lesions (n = 54) on MRI after radiotherapy of brain metastases underwent dynamic {sup 18}F-FET PET. Tumour-to-brain ratios (TBRs) of {sup 18}F-FET uptake and 62 textural parameters were determined on summed images 20-40 min post-injection. Tracer uptake kinetics, i.e., time-to-peak (TTP) and patterns of time-activity curves (TAC) were evaluated on dynamic PET data from 0-50 min post-injection. Diagnostic accuracy of investigated parameters and combinations thereof to discriminate between brain metastasis recurrence and radiation injury was compared. Diagnostic accuracy increased from 81 % for TBR{sub mean} alone to 85 % when combined with the textural parameter Coarseness or Short-zone emphasis. The accuracy of TBR{sub max} alone was 83 % and increased to 85 % after combination with the textural parameters Coarseness, Short-zone emphasis, or Correlation. Analysis of TACs resulted in an accuracy of 70 % for kinetic pattern alone and increased to 83 % when combined with TBR{sub max}. Textural feature analysis in combination with TBRs may have the potential to increase diagnostic accuracy for discrimination between brain metastasis recurrence and radiation injury, without the need for dynamic {sup 18}F-FET PET scans.

We retrospectively analysed CT findings of 47 cystic brain lesions of 44 patients, in which operation, biopsy or follow-up study was needed for their final diagnosis. The results were as follows: 1. The etiologic diseases of cystic brain lesions were 15 cases of brain abscess, 9 cases of astrocytoma, 5 cases of glioblastoma multiforme, 3 cases of meningioma, 5 cases of craniopharyngioma, 1 case of hemangioblastoma, 2 cases of dermoid cyst and 4 cases of metastasis. 2. We analyses the cystic lesions in view of their number, location, shape, perifocal edema, mass effect, wall and its thickness, evenness and characteristics of their inner and outer surfaces, mural nodule, calcification and contrast enhancement. a. 13.3% of brain abscess and 75% of metastases were multiple in number, but the remainder showed single lesion. b. The shape of cystic lesions were round or ovoid in 68%, lobulated in 8.5% and irregular in 23.5%, and no demonstrable difference of shape were noticed in different disease. c. In brain abscess, the wall of cystic lesions tend to be thin, even and smooth in inner surface, but the outer surfaces were equally smooth or irregular. d. Mural nodules were found in nearly half of the cases of astrocytoma, glioblastoma multiforme, metastasis and hemangioblastoma, but the brain abscess and dermoid cyst contained no mural nodule. e. Meningiomas were found to be attached to dura mater and showed thickening of the inner table of adjacent skull or of the falx. f. The presence of preceding infectious disease may be helpful in the diagnosis of brain abscess, but in 20% there were no demonstrable preceding infection. g. Lung cancer was confirmed as primary site in two of the cystic metastatic disease, but other 2 cases showed no demonstrable primary malignancy

During the last French radiation oncology society annual congress, the therapeutic options for the management of brain metastases were presented. The indications and limits of surgery, stereotactic radiotherapy and whole brain radiotherapy, as well as their benefit in terms of overall survival, local control and improvement of the functional and neuro-cognitive status were discussed. The prognosis significance of the different phenotypes of breast cancer on the risk for BM as well as their roles in the treatment of brain metastases were also described. Surgery improves overall survival for patients with a single brain metastase and should be considered in the case of symptomatic lesions. The overall survival of patients treated with stereotactic radiotherapy do not differ from that of patients treated with surgery. These treatments should be mainly considered for patients with good performance status, one to three small brain metastases (< 3 cm) and limited extracranial disease. Whole brain radiotherapy is more and more discussed in adjuvant setting due to potential late neuro-cognitive toxicity. This toxicity could be improved with the development of techniques sparing the hippocampus. HER2+ and triple-negative breast cancer patients are at increased risk for brain metastases. Prognosis of these patients differs as the overall survival of HER2+ patients has improved with anti-HER2 therapies. The optimal combination of local and systemic therapies remain to be determined.

Thyroid follicular carcinoma is able to produce metastatic lesions before the vanishing of the primary lesion. We present a case of a woman with a lytic, solitary, asymptomatic parietal bone lesion of 2 years of evolution. Autopsy revealed a thyroid gland with two small cystic areas and renal metastasis. Thyroid carcinoma should be included in the differential diagnosis in cases of lytic bone lesions with long evolution in patients 60 years of age or older.

Pharmacologic inhibition of MLK3 kinase activity blocks the in vitro migratory capacity of breast cancer cells but has no effect on breast cancer brain metastasis in a mouse xenograft model.

Full Text Available Brain metastasis of breast cancer is an important clinical problem, with few therapeutic options and a poor prognosis. Recent data have implicated mixed lineage kinase 3 (MLK3 in controlling the in vitro migratory capacity of breast cancer cells, as well as the metastasis of MDA-MB-231 breast cancer cells from the mammary fat pad to distant lymph nodes in a mouse xenograft model. We therefore set out to test whether MLK3 plays a role in brain metastasis of breast cancer cells. To address this question, we used a novel, brain penetrant, MLK3 inhibitor, URMC099. URMC099 efficiently inhibited the migration of breast cancer cells in an in vitro cell monolayer wounding assay, and an in vitro transwell migration assay, but had no effect on in vitro cell growth. We also tested the effect of URMC099 on tumor formation in a mouse xenograft model of breast cancer brain metastasis. This analysis showed that URMC099 had no effect on the either the frequency or size of breast cancer brain metastases. We conclude that pharmacologic inhibition of MLK3 by URMC099 can reduce the in vitro migratory capacity of breast cancer cells, but that it has no effect on either the frequency or size of breast cancer brain metastases, in a mouse xenograft model.

Rare vertebral metastasis in a case of Hereditary Paraganglioma

Full Text Available Abstract Paragangliomas are rare tumours with a prevalence of 1/10000 to 1/30000. Tumors arising from the paraganglia are characteristically of low malignant potential. Vertebral metastases are exceedingly rare, and only isolated case reports have described them. The authors present the clinical course of a 47 years-old female patient with a familial paraganglioma [PGL] with vertebral metastastization, who underwent an intralesional tumor excision and corpectomy. Genetic screening demonstrated a new germinal frameshift mutation of the SDHB exon 6 [c.587-591DelC]. After surgery there was normalization of the analytical parameters and imagiologic screening. One year later she presented a new image in the the pedicle of T11 on the contralateral side of the surgical incision. She performed 2 treatments with MIBG and 1 cicle of radiotherapy that made the new lesion regress. Currently the patient does not present any clinical or analytical evidence of new metastasis. This case outlines the clinical course of a patient with a PGL syndrome for whom a rare vertebral metastasis was diagnosed. It highlights the importance of identifying patients with germline SDHB mutations, as these patients are at a high risk of developing malignant disease.

Although the thyroid gland is one of the most vascular organs of the body, metastatic disease in the thyroid is encountered infrequently. However, at autopsy, the incidence rate of thyroid metastasis ranges from 1.25% to 24%. The primary sites are the kidney, lung, breast, and gastrointestinal tract. We report a rare case of a hepatocellular carcinoma metastatic to the thyroid gland. The patient had multiple palpable masses in the anterior and left lateral neck along the internal jugular chain on physical examination 9 months after the initial diagnosis of liver tumor. These masses were confirmed as metastasis from hepatocellular carcinoma by ultrasonography-guided 16-G core needle biopsy. We discuss the sonographic findings of thyroid metastasis and their use as an additional aid for differentiating between unknown primary tumor and thyroid metastasis.

Pulmonary Metastasis from Pseudomyxoma Peritonei

Full Text Available Pseudomyxoma peritonei (PMP is a rare clinical condition, where copious mucinous ascites accumulate in the peritoneal cavity due to dissemination of mucin-producing tumor. Because of this disseminating, yet nonmetastasizing, behavior, PMP attracts much interest from surgical oncologists in that aggressive locoregional therapy can give the opportunity of long survival and even cure. Although extra-abdominal metastasis is exceptionally rare, the lung is the most likely site in such a case. In this paper, the clinical findings and treatment of eleven cases with pulmonary metastasis from PMP were reviewed, including ten cases in the literature and one case which we experienced. The clinical features of PMP cases with pulmonary metastasis were similar to cases without pulmonary metastasis. The histological type was low-grade mucinous neoplasm in most cases. Pulmonary lesions were resected in seven cases in which abdominal lesions were controlled by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy or another therapeutic modality. Disease-free state was maintained in five cases at the end of the follow-up period. However, it should be noted that rapid progression after resection was seen in two cases, suggesting that biological features may have changed by surgical intervention.

The treatment of hepatic metastasis of colon cancer was in progress by new biochemical agents. Generally, a resection was the first alternative treatment against hepatic metastasis of colon cancer, but new antitumor agents were more effective than conventional antitumor agents. Disappearance of metastasis for colon cancer treated with only antitumor agents was commenced to report. We were experienced a case of transverse colon cancer without a recurrence lesion after five years from the resection of hepatic metastasis. A case was a 77-year-old man. He was operated against transverse colon cancer in February 2003. Pathological stage was ss, n0, Stage II. In April 2004, serum CEA was increased. CT examination was not detected a hepatic metastasis but ultrasound examination and MRI detected the metastasis at S7 lesion in the liver. In July 2004, he was admitted to S-1 and PSK until October 2004. In December 2004, the lesion of hepatic metastasis was reduced and serum CEA was decreased. But in September 2005, the metastatic lesion was re-grown. A resection for hepatic metastasis was executed in November 2005. After the resection for hepatic metastasis, he was admitted to UFT/ UZEL from January 2006 to October 2006. Present time( June 2011), the lesion of recurrence was not detected by several examinations (CT, MRI, Ultrasound etc).

Purpose: To report the outcome of patients with synchronous, solitary brain metastasis from non-small-cell lung cancer (NSCLC) treated with gamma knife stereotactic radiosurgery (GKSRS). Patients and Methods: Forty-two patients diagnosed with synchronous, solitary brain metastasis from NSCLC were treated with GKSRS between 1993 and 2006. The median Karnofsky performance status (KPS) was 90. Patients had thoracic Stage I-III disease (American Joint Committee on Cancer 2002 guidelines). Definitive thoracic therapy was delivered to 26/42 (62%) patients; 9 patients underwent chemotherapy and radiation, 12 patients had surgical resection, and 5 patients underwent preoperative chemoradiation and surgical resection. Results: The median overall survival (OS) was 18 months. The 1-, 2-, and 5-year actuarial OS rates were 71.3%, 34.1%, and 21%, respectively. For patients who underwent definitive thoracic therapy, the median OS was 26.4 months compared with 13.1 months for those who had nondefinitive therapy, and the 5-year actuarial OS was 34.6% vs. 0% (p < 0.0001). Median OS was significantly longer for patients with a KPS ≥90 vs. KPS < 90 (27.8 months vs. 13.1 months, p < 0.0001). The prognostic factors significant on multivariate analysis were definitive thoracic therapy (p = 0.020) and KPS (p = 0.001). Conclusions: This is one of the largest series of patients diagnosed with synchronous, solitary brain metastasis from NSCLC treated with GKSRS. Definitive thoracic therapy and KPS significantly impacted OS. The 5-year OS of 21% demonstrates the potential for long-term survival in patients treated with GKSRS; therefore, patients with good KPS should be considered for definitive thoracic therapy

Wang Shuxia; Boethius, J.

2004-01-01

Purpose: To retrospectively evaluate FDG-PET in differentiation of post-radiotherapy status: recurrence, radiation necrosis, malignant regression of low grade primary brain tumour, and to evaluate PET in terms of survival prediction. Material and methods: 117 irradiated patients (156 PET) were consecutively included. PET results were judged by a set of rigid follow-up standards. Brain metastases from lung carcinoma were further studied. Survival time was analysed with Kaplan-Meier method. Results: There were 61 true-positive, 2 false-positive, 15 false-negative, 51 true-negative PET; leaving 5 positive and 22 negative PET results indeterminate. PET positive predictive value was 96% in all and 100% in brain metastasis from lung carcinoma. PET negative predictive value was 55.6% among surgically selected cases. Survival time was significantly longer in patient's with negative PET, both brain metastasis and primary brain tumour. Conclusions: FDG-PET was a good method to pick up tumour recurrence from radiation necrosis, especially metastasis from lung carcinoma. FDG uptake could be used as a non-invasive parameter to predict patient's prognosis. (authors)

Abstract Rationale: Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. Patient concerns: We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. Diagnoses: Retroperitoneal metastasis of hepatic phase fascioliasis. Interventions: The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. Outcomes: After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. Lessons: To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

Full Text Available Nasopharyngeal carcinoma (NPC is prevalent in Taiwan and is characterized by a high frequency of nodal metastasis. The most common organs with distal metastases are the bones, lungs, and liver, with extremely rare cases to the pericardium. Herein, we report a rare case with NPC who presented with dyspnea and orthopnea. Serial studies, including pericardial biopsy, revealed NPC with pericardial metastasis and pericardial effusion. The tumor cells of both the original and metastatic tumors were positive for Epstein–Barr virus by in situ hybridization. This is the first histologically confirmed case of NPC with pericardial metastasis.

Lingual metastasis from renal cell carcinoma: a case report and literature review

Camillo Porta

Full Text Available Renal cell carcinoma (RCC accounts for the 3% of all solid tumors. Despite continuous improvement in the therapy regimen, less has been achieved in terms of enabling an earlier diagnosis: the neoplasia usually reveals its presence at an advanced stage, obviously affecting prognosis. The most frequent sites of secondary disease are shown to be lungs (50-60%, bone (30-40%, liver (30-40% and brain (5%; while the head and neck district seems to account for less than 1% of patients with primary kidney lesion. We report here the case of a 70-year old man who presented with acute renal failure due to abdominal recurrence of RCC 18 years post nephrectomy. After a few months of follow up without any systemic therapy due to the renal impairment, the patient presented a vascularized tongue lesion that was demonstrated to be a secondary localization of the RCC. This lesion has, therefore, been treated with microsphere embolization to stop the frequent bleeding and to lessen the unbearable concomitant symptoms it caused, such as dysphagia and pain. A tongue lesion that appears in a RCC patient should always be considered suspect and a multidisciplinary study should be conducted both to assess whether it is a metastasis or a primary new lesion and to understand which method should be selected, if necessary, to treat it (surgery, radiation or embolization. Lingual metastasis should be examined accurately not only because they seem to implicate a poor prognosis, but also because they carry a burden of symptoms that not only threatens patients’ lives but also has a strong impact on their quality of life.

Invasive pleomorphic lobular carcinoma (PLC) is an aggressive subtype of invasive lobular carcinoma of the breast, which has its own histopathological and biological features. The metastatic patterns for PLC are distinct from those of invasive ductal carcinoma. In addition, pancreatic metastasis from PLC is extremely rare. We report a rare case of a 48-year-old woman presenting with clinical gastrointestinal symptoms and pancreatic metastasis of PLC. The pancreatic tumor was composed of pleomorphic tumor cells arranged in the form of solid sheets and nests and as single files, with frequent mitotic figures, nucleolar prominence, high nuclear to cytoplasmic ratio and loss of cohesion. The malignant cells were positive for p120 (cytoplasmic) and GATA3 and negative for estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, E-cadherin, gross cystic disease fluid protein 15 and mammaglobin, which indicated a lobular carcinoma phenotype of the breast. To the best of our knowledge, this is one of the few reported cases in the literature of pancreatic metastasis of invasive lobular carcinoma of the breast, of which the definitive diagnosis was obtained only after surgery. Rare metastasis sites should be considered, particularly, when a patient has a medical history of PLC.

Medical and health economic assessment of radiosurgery for the treatment of brain metastasis

Full Text Available Background: Radiotherapy for patients suffering from malignant neoplasms has developed greatly during the past decades. Stereotactic radiosurgery (SRS is one important radiotherapeutic option which is defined by a single and highly focussed application of radiation during a specified time interval. One of its important indications is the treatment of brain metastases. Objectives: The objective of this HTA is to summarise the current literature concerning the treatment of brain metastasis and to compare SRS as a single or additional treatment option to alternative treatment options with regard to their medical effectiveness/efficacy, safety and cost-effectiveness as well as their ethical, social and legal implications. Methods: A structured search and hand search of identified literature are performed from January 2002 through August 2007 to identify relevant publications published in English or German. Studies targeting patients with single or multiple brain metastases are included. The methodological quality of included studies is assessed according to quality criteria, based on the criteria of evidence based medicine. Results: Of 1,495 publications 15 medical studies meet the inclusion criteria. Overall study quality is limited and with the exception of two randomized controlleed trials (RCT and two meta-analyses only historical cohort studies are identified. Reported outcome measures are highly variable between studies. Studies with high methodological quality provide evidence, that whole-brain radiotherapy (WBRT in addition to SRS and SRS in addition to WBRT is associated with improved local tumour control rates and neurological function. However, only in patients with single brain metastasis, RPA-class 1 (RPA = Recursive partitioning analysis and certain primary tumour entities, this combination of SRS and WBRT is associated with superior survival compared to WBRT alone. Studies report no significant differences in adverse events between

Olanzapine and Betamethasone Are Effective for the Treatment of Nausea and Vomiting due to Metastatic Brain Tumors of Rectal Cancer

Full Text Available Brain lesions originating from metastasis of colorectal cancer represent 3-5% of all brain metastases and are relatively rare. Of all distant metastases of colorectal cancer, those to the liver are detected in 22-29% of cases, while those to the lungs are detected in 8-18% of cases. In contrast, brain metastasis is quite rare, with a reported incidence ranging from 0.4 to 1.8%. Treatments for metastatic brain tumors include surgery, radiotherapy, chemotherapy and supportive care with steroids, etc. Untreated patients exhibit a median survival of only approximately 1 month. The choice of treatment for brain metastasis depends on the number of lesions, the patient's general condition, nerve findings and presence of other metastatic lesions. We herein report the case of a 78-year-old male who presented with brain metastases originating from rectal carcinoma. He suffered from nausea, vomiting, anorexia and vertigo during body movement. He received antiemetics, glycerol and whole brain radiation therapy; however, these treatments proved ineffective. Olanzapine therapy was started at a dose of 1.25 mg every night. The persistent nausea disappeared the next day, and the frequency of vomiting subsequently decreased. The patient was able to consume solid food. Olanzapine is an antipsychotic that has recently been used as palliative therapy for refractory nausea and vomiting in patients receiving chemotherapy. We consider that olanzapine was helpful as a means of supportive care for the treatment of nausea and vomiting due to brain metastasis.

Intraocular metastasis is the most common malignancy of the eye. The frequency of intraocular metastasis in all the patients dying of cancer is about 12% and ocular metastases will be detected more frequently in the future because the patients with malignant tumor are now living longer. Intraocular metastasis can cause a serious clinical problem such as blindness. The early recognition and treatment of intraocular metastasis are very important clinical oncologic issues to maintain vision and to maximize the quality of life. However, significance of intraocular metastasis is still under-evaluated for practicing oncologists. External beam radiotherapy is a safe, effective palliative treatment in terms of preserving both the vision and the eye globe.

Full Text Available Oral cavity is a rare target for metastasis with an incidence of 1% among all oral cancers. In 24% of such cases, oral metastasis is the first indication of an undiagnosed primary. Metastatic oral malignancies have been reported in the mandible, tongue, and gingiva. Although gingival metastasis has been reported from lung, prostate, rectal carcinoma in men and carcinoma of breast, adrenal glands, and genitalia in females, gingival metastasis from carcinoma of the penis has not been reported. Herein, a case of metastatic gingival carcinoma that developed after extraction of teeth from primary carcinoma of the penis is presented. An extensive literature search revealed no such similar case reports.

Solitary metastasis of a malignancy to the spleen is rare, particularly for gastric cancer. Only a few case reports have documented isolated splenic metastasis from early gastric cancer. We describe a case of splenic metastasis from early gastric cancer. A 60-year-old man underwent a distal gastrectomy for early gastric cancer. It infiltrated the submucosa with pathological nodal involvement (pT1bN2M0, stage IIB). One year after the gastrectomy, an abdominal computed tomography scan showed a low-density lesion, 17 mm in diameter, at the upper pole of the spleen. Positron emission tomography/computed tomography showed focal accumulation of fluorine-18 fluorodeoxyglucose in the spleen without extrasplenic tumor dissemination or metastasis. We diagnosed splenic metastasis of gastric cancer, and performed a splenectomy. Histological examination confirmed moderately differentiated tubular adenocarcinoma and poorly differentiated adenocarcinoma (solid type) that was consistent with the features of the primary gastric cancer. The splenic tumor was pathologically and immunohistochemically diagnosed as a metastasis from the gastric carcinoma. More than 18 months after the splenectomy, the patient has had no evidence of recurrent gastric cancer. When solitary metastasis to the spleen is suspected during the postoperative follow-up of a patient with gastric cancer, a splenectomy is a potentially effective treatment.

Background: Gall bladder carcinoma is one of the most common cancers in India. Gall bladder cancer with metastasis to the breast is very rare. Herein we intend to report a case of carcinoma gall bladder with breast metastasis and a short review of the literature. Methods: This report describes an interesting and unusual case of gall bladder carcinoma presenting with breast metastasis. Case report: A 38-year lady presented with complaints of right abdominal pain. Bilateral breast examination showed 2 2 cm palpable lump in the upper outer quadrant of the left breast. Contrast-enhanced CT of the abdomen and pelvis showed circumferential thickening of gall bladder with the loss of fat plane with the adjacent liver parenchyma. Biopsy from the breast lump was reported as metastatic adenocarcinoma compatible with primary in the gall bladder. Whole body PET-CT showed gall bladder mass with abdominal and pelvic nodes with metastasis to liver, left breast, C7 vertebral body and left supra-clavicular node. She was diagnosed to have disseminated carcinoma gall bladder with liver, breast and supraclavicular nodal metastasis. She received palliative chemotherapy with gemcitabine and carboplatin and radiotherapy to C7 vertebra. After receiving 3 cycles of chemotherapy, chemotherapy was changed to the second line with single agent capecitabine. In spite of two lines of chemotherapy, she succumbed to disease progression and expired. Conclusion: There are limited examples of gall bladder adenocarcinoma with simultaneous metastasis to breast in the English literature. Our case showed an unusual dissemination of gall bladder cancer

Full Text Available ABSTRACT CONTEXT: Pancreatic metastases from primary malignant tumors at other sites are rare, constituting about 2% of the neoplasms that affect the pancreas. Pancreatic metastasis from breast cancer is extremely rare and difficult to diagnose, because its clinical and radiological presentation is similar to that of a primary pancreatic tumor. CASE REPORT: A 64-year-old female developed a lesion in the pancreatic tail 24 months after neoadjuvant therapy, surgery and adjuvant radiation therapy for right-side breast cancer (ductal carcinoma. She underwent distal pancreatectomy with splenectomy and left adrenalectomy, and presented an uneventful outcome. The immunohistochemical analysis on the surgical specimen suggested that the lesion originated from the breast. CONCLUSION: In cases of pancreatic lesions detected in patients with a previous history of breast neoplasm, the possibility of pancreatic metastasis should be carefully considered.

Late brain metastases from breast cancer: clinical remarks on 11 patients and review of the literature.

Late brain metastases from breast cancer are a rare event. Only a few cases have been reported in the English literature. The authors describe the clinical and pathological remarks, together with treatment modalities, removal extent and overall survival, of 11 patients in whom brain metastases were detected more than 10 years from the primary tumor. Between January 1997 and April 2001, we hospitalized 11 patients, all females, with a histologically proven diagnosis of brain metastasis from breast invasive ductal carcinoma. We defined 'late metastasis' as those metastases that appeared at least 10 years after the breast cancer diagnosis. The median age at the moment of brain metastasis diagnosis was 59 years (range, 47-70), with a median latency time from breast cancer diagnosis of 16 years (range, 11-30). Ten patients underwent surgery followed by adjuvant radiotherapy (whole brain radiotherapy). Two of them received, after whole brain radiotherapy, stereotaxic radio surgery treatment. One patient had stereotaxic brain biopsy, performed by neuronavigator, followed by palliative corticosteroid therapy. Median survival after brain metastasis diagnosis was 28 months (range, 3 months-4 years). Although late brain metastases are a rare event, specific neurologic symptoms and neuroradiological evidence of a cerebral neoplasm should be correlated to the presence of a cerebral metastasis, in a patient with a previous history of breast cancer. The longer latency time from breast cancer to brain metastasis could be explained by the "clonal dominance" theory and by different genetic alterations of the metastatic cell, which could influence the clinical history of the disease.

Peritoneal metastasis is frequent mode of dissemination of intraabdominal malignancies. Radiologic diagnosis of peritoneal metastasis has relied on indirect evidence on a barium UGI series and small bowel examination. With the advent of CT scanning, CT is capable of direct imaging of peritoneum. The sensitivity of CT in detecting peritoneal metastasis and CT manifestation of peritoneal metastatic lesions had reported occasionally, but rarely in Korea. So, authors illustrated the CT manifestation of peritoneal metastatic lesions in 32 cases of macroscopically proven cases in laparoscopy or laparotomy in Korea University Hae Wha Hospital during recent 4 years. The results are as follows. 1. Of total 32 cases, 18 cases were male and 14 cases were female. Age incidence was the most common in 6th decade. 2. The most common type of malignancy that cause peritoneal metastasis was the stomach cancer and next common type of malignancies were pancreas cancer in men and ovarian cancer in women. 3. Of total 32 cases of peritoneal metastasis which was confirmed by laparoscopy or laparotomy macroscopically, 23 cases (72%) were detected peritoneal thickening and/or omental pathology by CT, and the remaining 9 cases (28%) were not detected by CT. 4. Ascites was present in 19 cases (59%). 5. Parietal peritoneal thickening was present in 16 cases (50%) by CT and sheetlike pattern was the most common findings. The patterns of peritoneal thickening was relatively nonspecific and was not correlated with primary tumor type. 6. Tumor involvement of greater omentum by CT was present in 19 cases (59%). There were 7 cases of smudged appearance pattern, 6 cases of nodular pattern, 6 cases of omental cake pattern and no cystic mass pattern. The patterns of omental pathology was relatively nonspecific and was nor correlated with primary tumor type

Apropos of a case of cutaneous metastasis from laryngeal cancer with review of literature

Full Text Available Cutaneous metastasis from laryngeal carcinoma is a rare occurrence. A 55-year-old male patient with supraglottic cancer was treated with concurrent chemoradiation. Eighteen months later, he presented with ulceroproliferative growth on dorsum of the right hand. Biopsy revealed metastatic squamous cell carcinoma. Further investigations revealed underlying bone destruction with lung metastasis. In view of poor general condition and widespread dissemination of disease, palliative radiotherapy was delivered to the hand of the patient. He achieved satisfactory palliation in form of pain relief, control of bleeding, and discharge. The present report serves to emphasize the importance of properly diagnosing metastatic spread to unusual sites. Such metastasis is rare and is associated with a poor prognosis. Treatment is usually aimed at providing pain relief in these patients with limited life expectancy. Hence, we present a case of extensive cutaneous metastasis from laryngeal carcinoma with review of the literature.

Breast cancer can metastasize to any organ; however, distant metastases are unusual at the time of diagnosis. Furthermore metastasis to skeletal muscle is an uncommon manifestation of malignancy. We report a case of a 45-year-old woman diagnosed with cancer of the left breast with metastases to the ipsilateral intercostal muscle. To the best of our knowledge this is the first report of intercostal muscle metastasis from breast cancer in the English literature

Full Text Available Ectopic adrenocorticotropic hormone (ACTH syndrome is an uncommon disorder and comprises about 15% of all patients with Cushing's syndrome (CS. Duodenal carcinoids are rare, indolent tumors usually associated with a benign progression. We hereby report a rare case of CS resulting from ectopic ACTH secretion from a duodenal neuroendocrine tumor (NET presenting with liver metastasis. A 37-year-old female presented with abdominal discomfort and dyspepsia of 1-month duration. Ultrasound abdomen suggested a well-defined hypoechoic lesion in the left lobe of the liver, suggestive of neoplasia. On clinical examination, she had Cushingoid features and persistent hypokalemia. Midnight ACTH and cortisol levels were grossly elevated at 1027 pg/ml (n < 46 pg/ml and 87.56 μg/dl (n < 7.5 μg/ml, respectively. Both overnight and high-dose dexamethasone suppression test confirmed nonsuppressed cortisol levels - 86.04 and 84.42 μg/dl (n < 1.8 μg/ml, respectively. Magnetic resonance imaging brain showed a structurally normal pituitary gland. Computed tomography scan of the abdomen revealed hepatic lesion with bilateral adrenal enlargement. A diagnosis of ectopic ACTH-dependent CS was made. Intraoperatively, a duodenal lesion of 0.5 cm × 0.5 cm was identified alongside an 8 cm × 6 cm exophytic lesion in segment IV of the liver. Frozen section of the duodenal lesion was positive for NET. She underwent a Whipple's surgery, cholecystectomy, and left hepatic lobectomy. Postoperatively, she showed clinical and biochemical remission. Herewith, we report the third case of duodenal carcinoid tumor presenting as ectopic ACTH syndrome and the first with liver metastasis.

I-Ting Liu

2016-06-01

Full Text Available Carcinoma of the ampulla of Vater is a rare gastrointestinal tumor. Additionally, cutaneous metastasis from such an internal malignancy is also uncommon. We reported the case of a 55-year-old man afflicted with ampullary carcinoma with cutaneous metastasis. The patient did not undergo the standard Whipple procedure but received chemotherapy due to apparent left neck lymph node metastasis noted by initial PET/CT imaging. The skin metastasis presented as a left neck infiltrating purpuric lesion, which was confirmed by skin biopsy approximately one year after the patient's disease was first diagnosed. Thereafter, the patient received further chemotherapy pursuant to his course of medical management. Skin metastasis usually represents a poor patient prognosis. In these cases, treatment of cutaneous metastasis typically includes systemic chemotherapy and local management such as radiation therapy or tumor excision. And when choosing a chemotherapy regimen for the ampullary cancer, the histological subtypes (intestinal or pancreatobiliary should be comprehensively considered. In our review of the literature, the intestinal type seems to have less distant lymph node metastasis, advanced local invasion, as well as recurrence than pancreatobiliary type of ampullary cancer.

Cholangiocarcinoma presenting as a solitary epididymal metastasis: a case report and review of the literature

Bailey David M

2007-08-01

Full Text Available Abstract Background Solid tumor metastasis to the epididymis is a rare occurrence and is mostly discovered incidentally at autopsy or after therapeutic orchidectomy for prostate cancer. Other primary carcinomas that have been demonstrated to metastasize to the paratesticular region include those originating in the stomach, kidney, ileum, and colon. Case presentation A 72-year-old gentleman presented with a firm and tender mass involving the right epididymis. On examination, he was jaundiced. Computed tomography of the abdomen demonstrated an obstructive stricture of the extra-hepatic bile ducts, in keeping with a cholangiocarcinoma, through which a metal stent was endoscopically inserted for symptomatic relief. Subsequent right radical orchidectomy yielded a diffusely infiltrative adenocarcinoma obliterating the epididymis, extending into the rete testis, vas deferens and spermatic cord and showing widespread vascular and perineural invasion. Residual epididymal, rete, and testicular tubules showed no in situ neoplasia. Morphologically and immunohistochemically the features were in keeping with a metastasis from a primary cholangiocarcinoma. Conclusion Only two cases of bile duct carcinoma metastasising to the male genital tract have previously been reported in the literature, the testis being the main site of metastasis in both cases. To our knowledge, this is the first described case of cholangiocarcinoma metastasising primarily to the epididymis, and presenting as a solitary epididymal metastasis in the absence of disseminated disease. It serves to highlight the importance of performing a thorough examination of the male external genitalia both clinically, in the follow up of cancer patients, and at autopsy.

Metachronous brain and intramedullary spinal cord metastases from nonsmall-cell lung cancer: A case report

Directory of Open Access Journals (Sweden)

Wen-Chih Liu

2012-05-01

Full Text Available A 44-year-old man had a brain tumor secondary to lung adenocarcinoma and underwent craniectomy to remove the brain tumor. After postoperative whole-brain radiation therapy, he underwent pneumonectomy followed by chemotherapy, mediastinal radiotherapy, and target therapy for lung cancer. Thirty-six months after the initial brain surgery, he suffered from neck pain and right upper limb numbness that rapidly progressed to upper extremity weakness and paralysis in 2 months. Magnetic resonance imaging demonstrated an intramedullary spinal cord lesion at the C4 level. Laminectomy and gross intramedullary tumor removal were performed. The patient’s neurological function improved after the operation. Nevertheless, 4 months after the intramedullary tumor removal, he began to show multiple metastases. Unfortunately, the patient died from respiratory failure 8 months after diagnosis with intramedullary spinal cord metastasis. In this case, early diagnosis and aggressive surgical treatment combined with postoperative radiotherapy and chemotherapy might have provided this patient with a prolonged survival and better quality of life.

Brain metastasis affects one third of patients with HER2-positive breast cancer after treatment with trastuzumab. Surgical resection and radiation therapy are often unsuccessful at accomplishing complete control of metastasis. Lapatinib is presumed to cross the blood-brain barrier, and exhibits clinical activities for treatment of HER2-positive breast cancer. A 43-year-old woman was treated for early breast carcinoma with total mastectomy, axillary lymph-node dissection, and adjuvant chemotherapy with cyclophosphamide plus doxorubicin. After the end of adjuvant trastuzumab therapy, she was diagnosed with panhypopituitarism due to pituitary metastasis. Surgical removal and whole brain radiation therapy were performed, but a portion of viable tumor remained. Only taking lapatinib, the size of the metastatic lesion began to shrink. Trastuzumab may have controlled the micro-metastasis of breast cancer, but it was unable to control its progression to the central nervous system. Lapatinib is a possible option for HER2-positive metastatic breast cancer patients with brain metastasis.

Purpose: To assess the utility of the Radiation Therapy Oncology Group Recursive Partitioning Analysis (RPA) and Score Index for Radiosurgery (SIR) stratification systems in predicting survival in patients with brain metastasis treated with Gamma Knife radiosurgery (GKRS). Methods and Materials: A total of 185 patients were included in the study. Patients were stratified according to RPA and SIR classes. The RPA and SIR classes, age, Karnofsky Performance Status (KPS), and systemic disease were correlated with survival. Results: Five patients were lost to follow-up. Median survival in patients in RPA Class 1 (30 patients) was 17 months; in Class 2 (140 patients), 10 months; and in Class 3 (10 patients), 3 months. Median survival in patients in SIR Class 1 (30 patients) was 3 months; in Class 2 (135 patients), 8 months; and in Class 3 (15 patients), 20 months. In univariate testing, age younger than 65 years (p = 0.0004), KPS higher than 70 (p = 0.0001), RPA class (p = 0.0078), SIR class (p = 0.0002), and control of the primary tumor (p = 0.02) were significantly associated with improved outcome. In multivariate analysis, KPS (p < 0.0001), SIR class (p = 0.0008), and RPA class (p = 0.03) had statistical value. Conclusions: This study supports the use of GKRS as a single-treatment modality in this selected group of patients. Stratification systems are useful in the estimation of patient eligibility for GKRS. A second-line treatment was necessary in 30% of patients to achieve distal or local brain control. This strategy is useful to control brain metastasis in long-surviving patients.

Invasive lobular carcinomas are the second most common type (5% to 15%) of invasive breast carcinomas. The most frequent sites of breast cancer metastasis are the local and distant lymph nodes, brain, lung, liver, and bones; metastasis to the gastrointestinal system, especially to the stomach, is rare. When a mass is detected in an unusual place in a patient with invasive lobular carcinoma, it should be kept in mind that such a mass may be either a second primary carcinoma or the metastasis o...

Distant metastasis accounts for the vast majority of deaths in patients with cancer. Breast cancer exhibits a distinct metastatic pattern commonly involving bone, liver, lung, and brain. Breast cancer can be divided into different subtypes based on gene expression profiles, and different breast cancer subtypes show preference to distinct organ sites of metastasis. Luminal breast tumors tend to metastasize to bone while basal-like breast cancer (BLBC) displays a lung tropism of metastasis. However, the mechanisms underlying this organ-specific pattern of metastasis still remain to be elucidated. In this review, we will summarize the recent advances regarding the molecular signaling pathways as well as the therapeutic strategies for treating breast cancer lung metastasis.

NONE

2015-06-15

Purpose: To evaluate the effects of leaf with or without interdigitation in multiple brain metastasis volumetric modulated arc therapy (VMAT) plans. Methods: Twenty patients with 2 to 6 brain metastases of our hospital were retrospectively studied to be planned with dual arc VMAT using Monaco 3.3 TPS on the Elekta Synergy linear accelerator. The prescription dose of PTV was 60Gy/30 fractions. Two plans with or without leaf interdigitation were designed. The homogeneity index (HI), conformity index (CI), dose volume histograms (DVHs), monitor unit (MU), treatment time (T), the segments, the dose coverage of the target, were all evaluated. Results: The plans with leaf interdigitation could achieve better CI (p<0.05) than without leaf interdigitation, while no significant difference were found in HI (p> 0.05) and the dose coverage of the target (p> 0.05).The MU,T, and the segments of the plan with leaf interdigitation were more than the plan without leaf interdigitation (p<0.05). There was no significant difference found in radiation dose of spinal cord, lenses and parotids, while the maximum dose of brain stem of leaf without interdigitation was higher than leaf with interdigitation (p< 0.05). It was worth noting that the areas of low dose regions with leaf interdigitation plan were much less than the without leaf interdigitation plan in the doublication planes (p< 0.05). Conclusion: This study shows that leaf with interdigitation has some advantages than leaf without interdigitation in multiple brain metastasis VMAT plans although the clinical relevance remains to be proven.

Long bone metastasis in cervical cancer is a rare presentation generally seen in the lumbar column or ribs. The reported rates of bone metastases are between 15%-29%. It is associated with poor prognosis. Bone scan and magnetic resonance imaging are useful techniques for diagnosis. In this case report, a 32-year old female with a previous history of cervical carcinoma FIGO stage IIIA presented with severe pain and swelling in her right humerus. X-ray and magnetic resonance imag...

Metastasis of lung cancer to the penis is very rare; it causes various clinical symptoms seriously affecting the quality of life. Early recognition and appropriate management will likely enhance survival in these patients. Here, we report a case of penile metastasis secondary to pulmonary carcinoma along with a review of the literature. One case of penile metastasis secondary to pulmonary carcinoma was detected in a 51-year-old patient who was admitted to the First Affiliated Hospital of Sun Yat-Sen University with persistent cough along with swelling of the perineum and penis. The clinical features, diagnosis, and treatment of this disease along with a relevant literature are reviewed and discussed. A MEDLINE search was performed to identify similar reports in the literature. CT scan revealed lung mass, and a glans penis ulcer and enlargement of inguinal lymph nodes was discovered upon physical examination. CT-guided percutaneous puncture of the lung mass revealed adenocarcinoma of lung, and biopsies of the glans penis ulcer and inguinal lymph nodes confirmed metastatic adenocarcinoma. The patients received chemotherapy and died of acute pulmonary embolism in less than 2 months. Metastasis of lung cancer to the penis is extremely rare. It presents an advanced form of lung cancer, and thus survival is extremely short. Although treatment of penile metastasis is almost always palliative, early recognition may enhance survival for these patients.

In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate. Of 172 post-operative cases, 20.8% (11/53) of those with lymph node metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymph node metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.).

Unusual patterns of cardiac metastasis were noted in three cases of hepatocellular carcinoma (HCC): one patient was noted to have a large right ventricular (RV) tumor mass with intracavitary growth and myocardial invasion; the second had massive pulmonary and left atrial (LA) metastasis; and the third patient had a right atrial tumor mass with concomitant RV and LA involvement. Tumor implantation to the RV without right atrial involvement and extensive myocardial invasion is unusual in HCC. The LA involvement is probably related to tumor growth from the pulmonary veins following massive metastasis to the lung, direct invasion of the atrial septum or tumor implantation via a subclinical right-to-left shunt through the patent foramen ovale. To the best of our knowledge, such unusual intracavitary metastases in HCC have not been reported previously. Cardiac metastasis, without local gross recurrence, may be one of the presentations after lobectomy in patients with HCC.

Full text: Osteosarcoma is considered the most common malignant primary bone tumour in children and adolescents. The lungs are the common sites of metastasis, which, if present, are associated with poor prognosis. Imaging workup includes x-ray, computed tomography, nuclear resonance imaging and bone scintigraphy in order to diagnose, help to choose appropriate treatment and prognosticate this disease. Chemotherapy is used to increase survival rate and to control the occurrence of lung metastasis. CASE 1: ELWS, male, 6 years old. The patient had a left knee trauma followed by increase in size and pain over 15 days. Knee x-ray showed a voluminous lesion and densely calcified tissue in the left knee, with soft tissue involvement. Chest x-ray showed multiple nodular dense lesions diffusely involving the lungs. Left knee MRI showed a neoplasm involving the distal epiphysis of the femur with extension from the bone marrow to the trochanteric region. Biopsy diagnosed small cell osteosarcoma. Chest computed tomography showed multiple opacities in the parenchyma of both lungs, most with calcification, predominantly in the cortical region. Bone scintigraphy showed intense uptake of the radiopharmaceutical in the distal half of the left femur and focal areas of increased uptake in the skull, left humerus, right scapula, thoracic soft tissue (mostly in the right side, in the same place as the pulmonary metastasis seen in the chest computed tomography), 12th thoracic vertebra, 4th lumbar vertebra and in the pelvis. CASE 2: ACD, male 20 years old. The patient presented pain and increase in size of the right knee starting 5 months ago. Right knee x-ray: insufflating bony lesion in the proximal epiphysis of the right tibia compatible with osteosarcoma; increase in volume in soft tissue around the knee. Right knee MRI: voluminous expansive osteoblastic lesion hypointense in T1 and heterogeneous in T2, diffusely enhanced by the use of gadolinium-DTPA; the lesion involved almost

AbstractA 54 year old lady presented for routine excision of a scalp lesion thought clinically to represent a sebaceous cyst of the right occiput. 4 years earlier she underwent total abdominal hysterectomy and right salpingo-oophorectomy for 3 large uterine fibroids. Histo-pathological examination of the hysterectomy specimen revealed an incidental low-grade leiomyosarcoma. Staging imaging was negative for metastatic disease. She made an uneventful recovery and was treated further by adjuvant pelvic radiotherapy.She noticed an uncomfortable and unsightly cystic swelling on her occiput four years after hysterectomy and was referred for routine excision of what was believed to be a benign lesion. The lesion was excised and sent for histopathological examination. Microscopic analysis including immuno-histochemistry demonstrated an ER and PR positive metastatic deposit of leiomyosarcoma. The margins of excision were histologically clear of disease.At Multi-Disciplinary Team (MDT) discussion a diagnosis of metastatic scalp deposit from previous uterine leiomyosarcoma was made. Re-staging CT brain, thorax, abdomen and pelvis and MRI brain were negative for local recurrence or distant metastases. She is currently undergoing radiotherapy to the scalp and surrounding tissues and will be followed up closely by the involved teams.To the best of our knowledge, this is the first case described in the worldwide literature of isolated cutaneous metastasis to the scalp of uterine leiomyosarcoma without evidence of disseminated disease at other sites.Virtual slidesThe virtual slide(s) for this article can be found here: http:\\/\\/www.diagnosticpathology.diagnomx.eu\\/vs\\/1311834987345566.

Purpose: To evaluate the efficacy of stereotactic radiosurgery (SRS) in patients with solitary brain metastasis from extracranial primary cancer and to compare the outcome with that of external whole brain irradiation with or without surgical resection. Materials and Methods: Between September 1970 and November, 1995, 231 patients with solitary brain metastasis were treated at the Department of Radiation Oncology, University of Minnesota Hospital. One hundred twenty six patients (56%) were treated with external whole brain irradiation (WBI) only (Group 1), seventy three (32%) underwent surgical resection prior to WBI (Group 2) and thirty two (14%) underwent stereotactic radiosurgery (SRS) with WBI (Group 3). Lung (38%) was the most common site of primary cancer, followed by breast (15%), unknown primary (12%), gastro-intestinal tract (10%), skin (malignant melanoma: 9%), kidney (renal cell carcinoma: 8%) and others (9%). The median dose to the whole brain was 3750 cGy in 15 fractions (ranges from 2000 cGy to 5000 cGy). The median radiosurgical dose of 17.5 Gy (range, 12-40 Gy) was delivered to the 40%-90% isodose line encompassing the target. Eighteen patients were treated with SRS for recurrent or persistent disease following WBI and 14 patients received SRS as a boost in conjunction with WBI. Actuarial survival was calculated from the date of treatment according to the Kaplan-Meier method and statistical significance was assessed with the log-rank test. Results: The actuarial median survivals were 3.8 months for Group 1 (ranges from 1 to 84 months), 10.5 months for Group 2 (ranges from 1 to 125 months) and 9.8 months for Group 3 (ranges from 1 to 36 months). The survivals at one and two years were 19% and 6% for Group 1, 47% and 19% for Group 2, and 44% and 21% for Group 3, respectively. The survival advantage of Groups 2 or 3 over Group 1 was statistically significant (p < 0.0001 by log-rank test). There was no survival advantage of surgery (Group 2) over SRS

A rare case of the choroid plexus metastasis of renal-cell carcinoma is reported. A 58-year-old man was admitted on March 3, 1982, with complaints of mild headache and a transient attack of muscle weakness of the left upper extremity. He had undergone a left nephrectomy because of renal-cell carcinoma 2 years before this admission. A CT scan revealed a small mass in the right lateral ventricle that was markedly enhanced by the contrast medium. A carotid angiogram was normal, but a left vertebral angiogram showed a round tumor stain in the distal portion of the right posterior choroidal artery. To determine the nature of the tumor, it was successfully removed via the right frontal transventricular approach. The immediate recovery from the operation was uneventful, but the patient became semicomatose 6 hours later because of a large subdural hematoma over the left hemisphere. An emergency operation for clot removal and external decompression failed to improve the patient's status, and he died on the 3rd postoperative day. An histological examination of the tumor determined the diagnosis of clear-cell-type renal-cell carcinoma. The CT demonstration of choroid plexus metastasis is quite rare. To our knowledge, only two cases have been described.

Gastric cancer frequently presents intraperitoneal spread. Distant metastasis are rare. The authors describe a case of a 47-year-old white man, long-term cigarette smoker, who had a right upper lobe mass seen on plain films and computed tomography of the chest. A gastric adenocarcinoma was concomitantly diagnosed by endoscopic examination. A bronchoscopy guided biopsy showed that the lung mass was in fact a metastasis from gastric adenocarcinoma. In this article, the imaging findings of gastric cancer and the patterns of dissemination to other organs are reviewed. (author)

Glioblastoma multiforme is the most common primary brain tumor, despite an aggressive clinical course, less than 2% of patients develop extraneural metastasis. We present a 72-year-old male diagnosed with a right temporal glioblastoma due to headache. He underwent total gross resection surgery and after that the patient was treated with adyuvant therapy. Five months after the patient returned with trigeminal neuralgia, and MRI showed an infratemporal cranial mass which infiltrates masticator space, the surrounding bone, the temporal muscle and superior cervical and parotid lymph nodes. The patient underwent a new surgery reaching partial resection of the temporal lesion. After that the patient continued suffering from disabling trigeminal neuralgia, that's why because of the bad clinical situation and the treatment failure we decided to restrict therapeutic efforts. The patient died 3 weeks after the diagnosis of extracranial metastasis. Copyright © 2018 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U. All rights reserved.

An autopsy case of right ventricular cardiac metastasis from squamous cell carcinoma of the left hand

Directory of Open Access Journals (Sweden)

T. Kondo

2016-12-01

Full Text Available We here report a 60-year-old woman in whom autopsy revealed a metastasis in the right cardiac ventricle from a well-differentiated squamous cell carcinoma (SCC of the left hand. The tumors in the myocardium and left hand were both well-differentiated SCCs with keratinization and sporadic keratin pearls. High concentrations of heart failure markers together with a pericardial effusion suggested antemortem chronic heart failure. Our case is particularly unusual because there were no regional lymph node metastases and the cardiac metastasis was not one of multiple metastases; thus, hematogenous metastasis to the right side of the heart alone had occurred.

Full Text Available Ependymoma is one of the uncommon tumors of the central nervous system (CNS in the adult age group. These tumors have a distinct propensity for metastasis, both within and outside the CNS. However, dissemination at the time of first presentation and retrograde dissemination of the tumor is rare. We report the case of a patient with fourth ventricular anaplastic ependymoma who presented with left lateral ventricular metastasis which was anatomically different from the primary tumor. We describe the clinic-pathological detail of the patient and discuss the probable pathophysiological basis for this rare presentation and its significance in management of the patient.

Cranial irradiation in patients with brain metastasis. A retrospective study of timing

Ampil, F.L.; Burton, G.V.; Mills, G.M.

1999-01-01

A retrospective study was conducted to determine the importance of the interval between diagnosis of brain metastasis (BRM) and cranial irradiation (CI). The charts of 92 patients with a known diagnosis of cancer and suspected BRM as shown on radioimaging studies were reviewed retrospectively. The median interval between diagnosis and the onset of CI for BRM was five days; one group of 48 individuals received CI within an interval of five days, and another group of 44 patients after an interval of five days. Symptom palliation, objective responses to CI and survival were evaluated in both groups. Neither symptomatic and objective responses to treatment nor overall survival differed significantly between the patient groups. These observations suggest that while CI is beneficial to most patients with BRM, its timing after the diagnosis of BRM may not seriously affect patient outcome. (author)

In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate (p<0.05). Of 172 post-operative cases, 20.8% (11/53) of those with lymphnode metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymphnode metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.)

Full Text Available We report an extremely rare and unusual case of retroperitoneal and pelvic metastasis from primary squamous cell carcinoma of vallecula. Generally carcinoma oropharynx metastasizes to lungs, liver and bone while retroperitoneal and pelvic metastasis is rarely heard of. To the best of our knowledge this case is one of the scantly reported cases ever of this kind in the world.  A 60-year-old male presented with dysphagia and hoarseness of voice of four month duration.  Computed tomography (CT scan face and neck showed growth right vallecula. Biopsy of lesion showed squamous cell carcinoma. Metastatic work up was negative. He received definitive chemo-radiation. Patient during follow up presented with dyspepsia, abdominal discomfort and weight loss. Whole body positron emission tomography (WB PET scan revealed retroperitoneal and pelvic lymph node deposits which were confirmed as metastasis of squamous cell carcinoma by CT guided fine needle aspiration cytology (FNAC. Patient was exhibited palliative chemotherapy but his general condition deteriorated and he finally succumbed to his metastatic illness. This case is being reported to highlight its extreme rarity, the diagnostic and therapeutic challenges it presented and its overall dismal prognosis.

1987-01-01

The authors retrospectively reviewed and analyzed CT scans of fifty patients with solitary intracranial lesion selected from 118 patients who had been confirmed to have intracranial metastasis from 1979 to 1985. The results were as follows: 1. The most common primary tumors with solitary metastasis, in order of frequency, were lung cancer, breast cancer, choriocarcinoma, colon cancer, lymphoma and others. 2. Precontrast scans obtained in 35 cases showed cystic very low density in 20%, slightly low density in 9%, isodensity in 20%, high density in 51% when he densities of the lesions were compared with that of the normal brain tissue. 3. After contrast enhancement 43 out of 50 showed one of 4 patterns of enhancement. Homogeneous enhancement without necrosis were found in 26%, homogeneous enhancement with necrosis in 18%, ring-enhancement in 26% and irregular enhancement in 16%. No enhancement was found in 14%. 4. The locations of the metastatic lesions were intra axial in 45 and extra axial in 5. Among the intra axial lesions, the parietal lobe was the most common location. Extra axial metastases were epidural, calvarial and leptomeningeal. 5. Degrees of surrounding edema were mild in 32%, moderate in 19% and severe in 49%

WE-EF-BRA-10: Prophylactic Cranial Irradiation Reduces the Incidence of Brain Metastasis in a Mouse Model of Metastatic Breast Cancerr

Purpose: Prophylactic cranial irradiation (PCI) is a clinical technique used to reduce the incidence of brain metastasis and improve overall survival in select patients with acute lymphoblastic leukemia and small-cell lung cancer. We examined whether PCI could benefit breast cancer patients at high risk of developing brain metastases. Methods: We utilized our mouse model in which 500k green fluorescent protein (GFP)-labeled breast cancer cells injected into the tail vein of SCID/Beige mice resulted in brain metastases in approximately two-thirds of untreated mice. To test the efficacy of PCI, one set of mice was irradiated five days after cell injection with a single fraction of 4-Gy (two 2-Gy opposing fields) whole-brain irradiation on the XRAD 225Cx small-animal irradiator. Four controls were included: a non-irradiated group, a group irradiated two days prior to cell injection, and two groups irradiated 3 or 6 weeks after cell injection. Mice were sacrificed four and eight weeks post-injection and were evaluated for the presence of brain metastases on a fluorescent stereomicroscope. Results: The incidence of brain metastasis in the non-irradiated group was 77% and 90% at four and eight weeks, respectively. The PCI group had a significantly lower incidence, 20% and 30%, whereas the other three control groups had incidence rates similar to the non-treated control (70% to 100%). Further, the number of metastases and the metastatic burden were also significantly lower in the PCI group compared to all other groups. Conclusion: The timing of irradiation to treat subclinical disease is critical, as a small dose of whole-brain irradiation given five days after cell injection abrogated tumor burden by greater than 90%, but had no effect when administered twenty-one days after cell injection. PCI is likely to benefit breast cancer patients at high risk of developing brain metastases and should be strongly considered in the clinic.

Deploying swarm intelligence in medical imaging identifying metastasis, micro-calcifications and brain image segmentation.

al-Rifaie, Mohammad Majid; Aber, Ahmed; Hemanth, Duraiswamy Jude

2015-12-01

This study proposes an umbrella deployment of swarm intelligence algorithm, such as stochastic diffusion search for medical imaging applications. After summarising the results of some previous works which shows how the algorithm assists in the identification of metastasis in bone scans and microcalcifications on mammographs, for the first time, the use of the algorithm in assessing the CT images of the aorta is demonstrated along with its performance in detecting the nasogastric tube in chest X-ray. The swarm intelligence algorithm presented in this study is adapted to address these particular tasks and its functionality is investigated by running the swarms on sample CT images and X-rays whose status have been determined by senior radiologists. In addition, a hybrid swarm intelligence-learning vector quantisation (LVQ) approach is proposed in the context of magnetic resonance (MR) brain image segmentation. The particle swarm optimisation is used to train the LVQ which eliminates the iteration-dependent nature of LVQ. The proposed methodology is used to detect the tumour regions in the abnormal MR brain images.

Full Text Available A five-year-old male Boerboel presented for examination, collapsed for an unknown period of time. On clinical examination, multifocal subcutaneous masses and enlarged prescapular lymph nodes as well as neurological deficits that suggested a multifocal neurological syndrome were found. Fine needle aspirates of the prescapular lymph nodes revealed cells suggestive of osteosarcoma. Radiographs showed foci of mineralisation within the soft tissue masses as well as diffuse pulmonary metastasis and a caudodorsal mediastinal mass believed to be a Spirocerca lupi nodule. Computed tomography imaging, necropsy and histopathology confirmed S. lupi oesophageal neoplastic transformation (extraskeletal osteosarcoma, believed to be the primary lesion, and the majority of secondary metastasis to the brain, spine, heart, multiple muscular groups and abdominal organs. This is the first known report of extraskeletal osteosarcoma metastasis to the brain and spinal cord in a dog.

Full Text Available ABSTRACT Background Recently, especially in Japan, several researchers have suggested that colorectal cancer can develop not only through an adenoma-carcinoma sequence but also from normal mucosa via a de novo pathway, and that these de novo cancers have more aggressive malignant potential. We report a case of aggressive colon cancer resulting in systemic metastasis despite small tumour size. Case Presentation A 35-year-old woman presented at the referring hospital with swelling of the left cervical lymph node. Biopsy of the lymph node revealed metastatic adenocarcinoma; however, CT scan and mammography were unable to identify the site of the primary lesion. She was diagnosed with unknown primary cancer and referred to our hospital for further examination. Immunohistochemical reevaluation showed the cervical lymph node biopsy specimen to be positive for CDX2 and CK20 and negative for CK7 expression, leading us to suspect the presence of a primary colorectal cancer. We performed a total colonoscopy, and detected a small protruding lesion in the transverse colon. The tumour was only 12 mm in diameter, with a central depressed component and a severely thickened stalk, which suggested direct cancer invasion of the deep submucosa. We concluded that this lesion was the site of origin of the metastasis despite the small tumour size, and performed diagnostic endoscopic mucosal resection. The lesion was found to have an intramucosal cancer component, demonstrating that this lesion represented primary colon cancer. The patient was referred to the gastrointestinal oncology division for systemic chemotherapy. Conclusions In this case, immunohistochemical findings strongly suggested the existence of a colorectal cancer. The non-polypoid gross appearance of the tumour suggested that it can originate de novo , thus providing a valuable case in support of the aggressive malignant potential of a de novo colorectal cancer pathway.

Objective: To investigate the clinical metastasis features and the possibility of 3 dimensional radiotherapy of stage IV non-small cell lung cancer (NSCLC). Methods: The clinical materials of 546 patients with stage IV NSCLC and the relationship b T and N stage and metastasis were retrospectively analyzed. Results In 546 patients with stage IV NSCLC, the number with bone metastasis was 294, the number with brain metastasis was 167, the number with lung metastasis was 137, the number with liver metastasis was 79, the number with adrenal gland metastasis was 66, 37 with lymph node metastasis, 35 with subcutaneous metastasis and 10 with other organ metastasis. The number with single organ metastasis was 379 (69.4%) ,in which 37.7% with bone metastasis, 19.8% with brain metastasis, 16.9% with lung metastasis, 7.4% with liver metastasis, 7.4% with adrenal gland metastasis, 4.5% with lymph node metastasis, 5.5% with subcutaneous metastasis and 0.8% with other organ metastasis. The bone metastasis probability of T 3+4 patient was similar with T 1+2 (69.4%, 30.6%, χ 2 = 7.65, P = 0.067), but N 2+3 patient was more than N 0+1 (69.7%, 30.3%, χ 2 = 7.89, P = 0.044). The brain metastasis probability of T 3+4 patient was more than T 1+2 (70.7%, 29.3%, χ 2 = 10.64, P = 0.018), but N 2+3 patient was similar with N 0+1 (54.5%, 45.5%, χ 2 = 7.14, P = 0.079), and N 1+3+3 patient was more than N 0 (86.8%, 13.2%, χ 2 = 10.26, P = 0.024). Conclusions: In 546 patients with stage IV NSCLC, the most common metastatic organ is bone, the second is brain, the third is lung, the forth is liver, followed by adrenal gland; single organ metastasis is more common than multiple organ metastasis. The later the T stage is, the more severe is the metastasis. Through 3 dimensional radiotherapy, not only the quality of life of some stage IV patients is improved, but also the survival time was prolonged observably. (authors)

Development of Cerebral Metastasis after Medical and Surgical Treatment of Anal Squamous Cell Carcinoma

Full Text Available Squamous cell carcinoma of the anus is a relatively uncommon GI malignancy. When it does occur, it metastasizes in only a small minority of patients. Spread of anal squamous cell carcinoma to the brain is exceedingly rare, and has been previously reported only three times in the medical literature. We report the case of a 67 year old male who was diagnosed on presentation with a poorly differentiated anal squamous cell carcinoma that already had a solitary metastasis to the liver. While the tumors were initially responsive to chemoradiotherapy, the patient’s primary and liver lesions recurred. The patient then underwent synchronous abdominoperineal resection for the primary lesion and a liver lobectomy for the metastasis. Soon thereafter, the patient developed focal neurologic symptoms and was found to have an intracranial lesion that on biopsy demonstrated metastatic squamous cell carcinoma. This case highlights the fact that patients with a previous history of anal squamous cell carcinoma can occasionally develop cerebral metastasis. Furthermore, cerebral metastases from anal squamous cell carcinoma portend a dismal prognosis even in the face of aggressive medical and surgical therapy.

Breast metastasis from extra-mammary malignancy is rare. An incidence of 0.4% to 1.3% has been reported in literature. hTe primary malignancies that most commonly metastasize to the breast are leukemia, lymphoma, and malignant melanoma. In this report, two cases of pulmonary metastasis to the breast were presented. A 40-year-old female manifested a right breast mass of 2-month duration. Atfer physical examination was performed, a poorly deifned mass was noted in the upper outer quadrant of the right breast. Another 49-year-old female manifested right breast mass of 5-day duration. A poorly deifned mass was noted in the lower inner quadrant of the right breast. Mammography results also revealed breast cancer. hTe patients underwent local excision. Atfer histological and immunohistochemical analyses were conducted, a primary lung carcinoma that metastasized to the breast was diagnosed. An accurate differentiation of metastasis to the breast from primary breast cancer is very important because the treatment and prognosis of the two differ signiifcantly.

Diffusion-weighted MRI (DWI) has been used in neurosurgical practice mainly to distinguish cerebral metastases from abscess and glioma. There is evidence from other solid organ cancers and metastases that DWI may be used as a biomarker of prognosis and treatment response. We therefore investigated DWI characteristics of cerebral metastases and their peritumoral region recorded pre-operatively and related these to patient outcomes. Retrospective analysis of 76 cases operated upon at a single institution with DWI performed pre-operatively at 1.5T. Maps of apparent diffusion coefficient (ADC) were generated using standard protocols. Readings were taken from the tumor, peritumoral region and across the brain-tumor interface. Patient outcomes were overall survival and time to local recurrence. A minimum ADC greater than 919.4 × 10 -6 mm 2 /s within a metastasis predicted longer overall survival regardless of adjuvant therapies. This was not simply due to differences between the types of primary cancer because the effect was observed even in a subgroup of 36 patients with the same primary, non-small cell lung cancer. The change in diffusion across the tumor border and into peritumoral brain was measured by the “ADC transition coefficient” or ATC and this was more strongly predictive than ADC readings alone. Metastases with a sharp change in diffusion across their border (ATC >0.279) showed shorter overall survival compared to those with a more diffuse edge. The ATC was the only imaging measurement which independently predicted overall survival in multivariate analysis (hazard ratio 0.54, 95% CI 0.3 – 0.97, p = 0.04). DWI demonstrates changes in the tumor, across the tumor edge and in the peritumoral region which may not be visible on conventional MRI and this may be useful in predicting patient outcomes for operated cerebral metastases

Esophageal Squamous Cell Carcinoma With Pancreatic Metastasis: A Case Report

Full Text Available Malignant tumors of pancreas are usually primary neoplasms and pancreatic metastases are rare findings. We are reporting a case of squamous cell carcinoma (SCC of the esophagus with pancreatic metastasis. A 59-year old woman was admitted with chief complaint of abdominal pain and mass. She was a known case of esophageal SCC since 4 years before when she had undergone transthoracic esophagectomy and cervical esophago-gastrostomy. In order to evaluate recent abdominal mass, CT scan was done which revealed septated cystic lesion in the body and the tail of the pancreas. Palliative resection of the tumor was performed and its histological study showed SCC compatible with her previously diagnosed esophageal cancer.

Excavated pulmonary nodules: an unusual clinical presentation of lung metastasis in two cases

Full Text Available Abstract Background Excavated pulmonary metastasis are rare. We present two cases of excavated pulmonary nodules proved to be metastases from osteosarcoma and gallblader lymphoma. Case presentation The first one is 39-year-old man in whom cholecystectomy made the diagnosis of primary non-Hodgkin's lymphoma of the gallbladder. He presented in chest CT scan excavated nodules that had been biopsied and confirmed the diagnosis of non hodgkin lymphoma. He underwent 8 courses of chemotherapy CHOP 21 with complete remission. The second one is an 21 years old man who presented a right leg osteoblastic osteosarcoma with only excavated pulmonary nodules in extension assessment. He had 3 courses of polychemotherapy API (doxorubicin, platinum, and ifosfamide with partial response. Unfortunately, he died following a septic shock. Review of the literature shows that excavated pulmonary nodules as metastasis are rare but we should consider this diagnosis every time we are in front of a cancer. Chest computed tomography is the best diagnosis imaging that could make this diagnosis. Differential diagnosis between benign and malignant bullous lesions is important because surgical excision affects survival in some malignancies. Conclusions Although pulmonary nodules are the most common cancer metastasis, a differential diagnosis of a concurrent primary malignancy should always be considered every time we have excavated lesions, even in patients with known malignant disease. Thorough chest evaluation is important, as multiple primary malignancies may occur concomitantly.

We present two cases of solitary necrotic nodules of the liver which on radiologic images mimicked hepatic metastasis. Solitary necrotic nodule of the liver is a rare but benign entity which histopathologically consists of an outer fibrotic capsule with inflammatory cells and a central core of amorphous necrotic material. The lesion was seen on contrast-enhanced CT as an ovoid-shaped hypoattenuating nodule; on CT during hepatic arteriography as enhancing nodule; on intraoperative US as a target-appearing hypoechoic nodule; on T2WI as a hyperintensity nodule, and on dynamic MR as a subtle peripheral enhancing nodule. Although the radiologic features are not specific, solitary necrotic nodule of the liver should be included in the differential diagnosis of hepatic metastasis.

Full Text Available Skeletal muscle metastasis of nonsmall cell lung carcinoma (NSCLC is a rare occurrence, and the most effective treatment modality is currently unknown. In this case presentation, we report a patient with NSCLC who underwent palliative radiotherapy for biceps muscle metastasis of NSLCS. Our case was a 49-year-old woman who had lung adenocarcinoma with biceps muscle metastasis. She had been followed up for 2 years due to Stage IV lung adenocarcinoma from whom a biopsy was taken from a painful mass in right arm that was found to be compatible with metastasis of lung adenocarcinoma. She had palliative radiotherapy for her painful mass and systemic chemotherapy was planned. After palliative radiotherapy, the pain originating from the metastatic mass in right biceps muscle alleviated. Palliative radiotherapy can be a valuable treatment option for cases with skeletal muscle metastasis.

1989-01-01

Twenty-seven cases of germ-cell tumors were examined with a CT scan in our clinic. In the 11 cases of metastasis or multi-localized tumors, the CT findings were studied in connection with the MRI findings. There were 6 cases of germ-cell tumors which had broad infiltrating tumors with multiple lesions on first admission. Their tumor sites were different from that in cases of malignant glioma, being frequently localized in the pineal and/or the suprasellar region, on the wall of the third and/or lateral ventricle, and in the region of the basal ganglia. Five of the cases of germ-cell tumors had metastasis with various patterns connected to a remote area - that is, to spinal cords, to the ventricular wall and basal cistern of the brain stem by CSF dissemination, to a lung by hematogeneous metastasis, and to the peritoneal wall or organs by a V-P shunt. The CT findings of germ-cell tumors were correlated mainly with the results of the histological diagnosis; they were found not to differ with the tumor site. The germinoma in the suprasellar region had less calcification than in the pineal region. Cysts, calcification, and an enlargement of the lateral ventricle on the tumor side were frequently seen in the germinoma of the basal ganglia. On the MRI of 5 cases of germinoma, the T 1 -weighted image revealed a slightly low or iso signal intensity, while the T 2 -weighted image showed a high signal intensity. In the case of multiple tumor lesions, some cases demonstrated different CT findings and radiosensitivities for each tumor. The possibility of a multicentric origin for the tumors is thus suggested in some cases of germ-cell tumors. (author)

Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.

Full Text Available The appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often related with the more frequently branchial cyst in young adults, but also rarely related with thyroid carcinomas. In most of these cases all such lesions may initially be considered as metastatic foci from a primary thyroid lesion. However, an alternative explanation by means of which ectopic thyroid tissue is associated with a branchial cyst has to be considered, especially if no primary tumour is observed in the histological examination of the thyroid gland. We present two case of solitary cystic lymph node metastasis of occult papillary carcinoma of the thyroid. [Cukurova Med J 2011; 36(1.000: 29-33

Every year, approximately 68,000 new cases of malignant melanoma are diagnosed in the US. Ethanol consumption inhibits metastasis of melanoma in mice, but the mechanism is not well understood. C57BL/6J ob/+ mice, given either water or 20% ethanol, were injected intravenously with B16-BL6 melanoma cells to determine pulmonary metastasis. The effects of ethanol on cell phenotypes and markers of the epithelial-to-mesenchymal transition were determined in cell culture. In mice, ethanol consumption inhibited experimental pulmonary metastasis. This inhibition was associated with decreased body weight, and levels of systemic leptin, and insulin. In cell culture, ethanol inhibited B16-BL6 cell motility, invasion, and anchorage-independent growth. Additionally, ethanol reduced Snai1 expression and increased E-cadherin expression. Lastly, ethanol increased the expression of Kiss1 metastasis-suppressor and the metastasis suppressor Nm23/nucleoside diphosphate kinase. In both animal and in cell culture conditions, ethanol inhibited the metastatic ability of B16-BL6 melanoma cells.

An upgrade of the helical tomotherapy technology by introducing variable fan-field width (dynamic jaws) reduced the penumbra in superior-inferior direction for the target. Possible implementation of this upgrade even for the cases of the targets with different dose prescriptions is proposed. An example of brain metastasis in proximity to the optical apparatus in need of the whole brain irradiation of 30 Gy and higher dose to the lesion is considered.

Unusual Upper Gastrointestinal Bleeding due to Late Metastasis from Renal Cell Carcinoma: A Case Report

Directory of Open Access Journals (Sweden)

Wen-Tsan Chang

2004-03-01

Full Text Available A case of recurrent massive upper gastrointestinal bleeding originating from metastatic renal cell carcinoma is reported. A 63-year-old woman underwent right nephrectomy 9 years previously and experienced no recurrence during follow-up. A gradually enlarging ulcerative tumor over the bulb of the duodenum and four subsequent episodes of massive bleeding from this tumor occurred between June 2001 and March 2002. The patient underwent surgery in April 2002 for intractable bleeding from the tumor. Renal cell carcinoma metastasis to the duodenum was confirmed from the surgical specimen. Upper gastrointestinal bleeding due to malignancy is very rare and the duodenum is the least frequently involved site. Furthermore, a solitary late renal cell carcinoma metastasis 9 years after a nephrectomy is extremely uncommon. This case suggests that life-long follow-up of renal cell carcinoma patients is necessary, owing to unpredictable behavior and the possibility of long disease-free intervals. In nephrectomized patients suffering from gastrointestinal bleeding, complete evaluation, especially endoscopic examination, is indicated. The possibility of late recurrent renal cell carcinoma metastasis to the gastrointestinal tract should be kept in mind, although it is rare. If the patient is fit for surgery, metastatectomy is the first choice of treatment.

MR imaging of bone marrow metastasis in patients with neuroblastoma. Comparison between mass-screened cases and clinically detected cases

Seventy-six patients with neuroblastoma who underwent bone marrow MRI were divided into two groups: the first group consisted of patients detected by mass screening (M group, n=55), and the second group of patients detected clinically (non-M group, n=21). Bone marrow metastasis was morphologically classified into two types, nodular type and diffuse type. We studied the incidence of bone marrow metastasis, relationship between the patterns of bone marrow metastasis and the presence of bone metastasis, and morphological changes of bone marrow metastasis after chemotherapy. In M group, the incidence of bone marrow metastasis was 7.3% (4 patients) and the patterns of bone marrow metastases were all nodular type not accompanied with bone metastasis and disappeared after chemotherapy. In non-M group, the incidence of bone marrow metastasis was 52.4% (11 patients). Bone marrow metastases had both patterns of metastasis. Forty-five per cent of diffuse type of bone marrow metastasis were accompanied with bone metastasis. All bone marrow metastases disappeared after chemotherapy, but in one of 11, there was recurrence of bone marrow metastasis. (author)

2015-02-01

Inguinal lymph node metastasis from adenocarcinoma arising at a colostomy site is extremely rare, and the significance of surgical resection for metastatic inguinal lymph nodes has not been established. An 82-year-old woman who had undergone abdominoperineal resection 27 years earlier was admitted to our hospital complaining of bleeding from a colostomy. Physical examination revealed that a tumor at the colostomy site directly invaded into the peristomal skin, and that a left inguinal lymph node was firm and swollen. Positron emission tomography/computed tomography scan demonstrated accumulation of (18)F-fluorodeoxy glucose into both the colostomy tumor and the left swollen inguinal lymph node, while there was no evidence of metastasis to liver or lungs. She underwent open left hemicolectomy with wide local resection of the colostomy, and dissection of left inguinal lymph nodes. Histological diagnosis was a moderately differentiated adenocarcinoma that directly invaded into the surrounding skin and metastasized to the left inguinal lymph node. The patient has been followed up for >5 years without any sign of recurrence. In general, inguinal lymph node metastasis from colorectal cancers is regarded as a systemic disease with a poor prognosis, and so systemic chemotherapy and radiotherapy, but not surgical lymph node dissection, are recommended. Considering the lymphatic drainage route in the present case, inguinal lymph node metastasis does not represent a systemic disease but rather a sentinel nodal metastasis from adenocarcinoma at a colostomy site. Surgical dissection of metastatic inguinal lymph nodes should be considered to enable a favorable prognosis in the absence of distant metastasis to other organs. © The Author 2014.

Radiolabeled cetuximab plus whole-brain irradiation (WBI) for the treatment of brain metastases from non-small cell lung cancer (NSCLC)

International Nuclear Information System (INIS)

Rades, Dirk; Nadrowitz, Roger; Buchmann, Inga; Meller, Birgit; Hunold, Peter; Noack, Frank; Schild, Steven E.

2010-01-01

Background and Purpose: The addition of systemic drugs to whole-brain irradiation has not improved the survival of patients with multiple brain metastases, most likely because the agents did not readily cross the blood-brain barrier (BBB). Radiolabeling of cetuximab was performed to investigate whether this antibody crosses the BBB. Case Report: A patient with multiple brain lesions from non-small cell lung cancer was investigated. The largest metastasis (40 x 33 x 27 mm) was selected the reference lesion. On day 1, 200 mg/m 2 cetuximab (0.25% hot and 99.75% cold antibody) were given. On day 3, 200 mg/m 2 cetuximab (cold antibody) were given. Weekly doses of 250 mg/m 2 cetuximab were administered for 3 months. Results: The reference lesion showed enhancement of radiolabeled cetuximab ( 123 I-Erbi) on scintigraphy; 123 I-Erbi crossed the BBB and accumulated in the lesion. The reference lesion measured 31 x 22 x 21 mm at 4 months. Enhancement of contrast medium was less pronounced. Conclusion: This is the first demonstration of cetuximab crossing the BBB and accumulating in brain metastasis. (orig.)

Several clinical guidelines indicate that brain metastasis screening (BMS) should be guided by disease stage in non-small cell lung cancer (NSCLC). We estimate that screening is performed more broadly in practice, and patients undergo brain imaging at considerable cost with questionable benefit. Our aim was to quantify the use and detection rate of BMS in a contemporary cohort staged with 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (PET-CT). We conducted a retrospective review of prospectively collected data from three major lung cancer referral centres in Brisbane between January 2011 and December 2015. Patients included had a new diagnosis of NSCLC and had undergone a PET-CT to stage extra-cranial disease. BMS was defined as dedicated brain imaging with contrast-enhanced computed tomography (CE-CT) or magnetic resonance (MR), in the absence of clinically apparent neurological deficits. A total of 1751 eligible cases were identified and of these 718 (41%) underwent BMS. The majority had CE-CT imaging (n = 703). Asymptomatic brain metastases (BM) were detected in 18 patients (2.5%). Of these patients, 12 had concurrent non-brain metastases. Only six patients (0.8%) had BM alone. The rate of detection increased with N-stage (P = 0.02) and overall stage (P < 0.001). It was 0.5%, 1%, 1.6% and 7.3% for stage I, II, III and IV respectively. The overall screening rate increased with T-stage (P = 0.001), N-Stage (P < 0.001) and overall stage (P < 0.001). Non-small cell lung cancer BMS practices remain at odds with published guidelines. The low number of occult BMs detected supports the existing international recommendations. Rationalising BMS would minimise the burden on patients and the health care system. © 2018 The Royal Australian and New Zealand College of Radiologists.

We present a case of a 21-year-old patient, bearer of femur primary osteosarcoma, who began with pain in the thoracic column. The metastasis of primary osteosarcoma has greater incidence on lungs, rarely affecting vertebras. We reviewed the literature about this disease and emphasized the image's characteristics on the several methods used (traditional radiographic exams, bone scintigraphy, computed tomography, magnetic resonance) and the main differential diagnostics.

There have been a limited number of studies giving the incidence of pleural metastasis from female genital tract tumors. An unusual case occurred of recurrent pleural malignant effusion associated with disseminated serous papillary endometrial adenocarcinoma (EC). A total abdominal hysterectomy with bilateral salpingo-oophorectomy, pelvic lymphadenectomy, appendectomy and omentectomy was performed. Treatment of the pleural malignant effusion consisted of thoracotomy with partial decortication, systemic chemotherapy and radiotherapy. The patient died of circulatory failure 8 months after the primary diagnosis. Although the pleura is a rare site of widespread EC, one should recognize the possibility of pleural spread from female genital tract neoplasms presenting with associated symptoms. Cytopathologic examination of the pleural effusion and the finding ofcarcinoma cells mandate an investigation for the primary site of the neoplasm by a multidisciplinary group.

Full Text Available Cytodiagnosis of cutaneous metastasis of renal cell carcinoma (RCC in the absence of history of primary tumor is difficult as it can be confused with other clear cell tumors. We report here a case of cytodiagnosis of cutaneous metastasis of RCC in a patient who had nephrectomy done 9 years back at some other centre, but did not have any records with him. Clinicians should be aware of the possibility of primary internal organ malignancy in patients presenting with cutaneous lesions and therefore conduct a careful examination and get necessary investigations. Prompt diagnosis and treatment will have its bearing on the eventual outcome.

Purpose: The study was conducted to determine whether immunohistochemical analysis of Ki-67, p53, and bcl-2 in patients with non-small-cell lung cancer is associated with a higher rate of brain metastases and whether the intrapatient expression of these biomarkers (in the primary tumors vs. brain lesions) is similar. Methods and Materials: At the M. D. Anderson Cancer Center, tumors from 29 case patients with primary lung tumor and brain metastasis and 29 control patients with primary lung tumor but no brain metastasis were resected and examined for immunohistochemical expression. Ki-67, p53, and bcl-2 were analyzed in resected primary lung, lymph node, and metastatic brain tumors. Each control patient was matched by age, gender, and histology to a patient with brain metastasis. Results: No significant differences in patient survival characteristics were detected between the case group and control group. Also, difference in patient outcome between the two groups was not generally predicted by biomarker analysis. However, when the groups were combined, the biomarker analysis was predictive for certain patient outcome end points. Using median values as cutoff points between low and high expression of biomarkers, it was observed that high expression of Ki-67 (>40%) in lung primaries was associated with poorer disease-free survival (p=0.04), whereas low expression of p53 in lung primaries was associated with poorer overall survival (p=0.04), and these patients had a higher rate of nonbrain distant metastases (p=0.02). The patients with brain metastases were particularly prone to developing nonbrain distant metastases if the percentage of p53-positive cells in brain metastases was low (p=0.01). There was a positive correlation in the expression of Ki-67 (p=0.02) (r 2 =0.1608), as well as p53 (p 2 =0.7380), between lung primaries and brain metastases. Compared to Ki-67 and p53, bcl-2 was the least predictive. Conclusion: Differences in biomarker expression between the

Full Text Available A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum. A flat, elevated esophageal cancer was identified by upper gastrointestinal endoscopy, and the macroscopic appearance indicated early-stage disease. From the cervical, thoracic and abdominal computed tomography images, there were no metastatic lesions except for the bone lesions. To confirm whether the bone lesions were metastatic, we performed bone biopsy. The histopathological diagnosis was bone marrow hyperplasia. It was crucial for treatment planning to establish whether the lesions were distant metastases. Here, we report a case of esophageal cancer with bone marrow hyperplasia mimicking bone metastasis.

Full Text Available Mutations on epidermal growth factor receptor (EGFR of adenocarcinomas of lung have been found to be associated with increased sensitivity to EGFR tyrosine kinase inhibitors and K-ras mutations may correlate with primary resistance. We aimed to explore the discordant mutation statuses of EGFR and K-ras between primary tumors and matched brain metastases in adenocarcinomas of lung. We used a sensitive Scorpion ARMS method to analyze EGFR mutation, and Sanger sequencing followed by allele-specific real-time polymerase chain reaction to analyze K-ras mutation. Forty-nine paired tissues with both primary adenocarcinoma of lung and matched brain metastasis were collected. Thirteen patients (26.5% were discordant for the status of EGFR between primary and metastatic sites. K-ras gene could be checked in paired specimens from 33 patients, thirteen patients (39.6% were discordant for the status of K-ras. In primary lung adenocarcinoma, there were 14 patients of mutant EGFR had mutant K-ras synchronously. This study revealed that the status of EGFR mutation in lung adenocarcinomas is relatively consistent between primary and metastatic sites compared to K-ras mutation. However, there are still a few cases of adenocarcinoma of lung showing discordance for the status of EGFR mutation. Repeated analysis of EGFR mutation is highly recommended if tissue from metastatic or recurrent site is available for the evaluation of target therapy.

We report a case of chemotherapy with FOLFOXIRI plus cetuximab for liver metastasis of sigmoid colon cancer. The patient was a 40's man who was diagnosed with sigmoid colon cancer with liver metastasis. Colonoscopy revealed a type 2 tumor with stenosis in the sigmoid colon. He underwent sigmoidectomy under laparotomy, and after the operation, received 7 courses of chemotherapy with FOLFOXIRI plus cetuximab. The liver tumor was sufficiently reduced, and laparotomy and liver right lobectomy were performed. Histopathology revealed a modified, Grade 2 tumor regression. He has been followed for 1 year 4months after the operation.

The role of glycosylation in breast cancer metastasis and cancer control

Full Text Available AbstractGlycosylation and its correlation to the formation of remote metastasis in breast cancer had been an important scientific topic in the last 25 years. With the development of new analytical techniques new insights were gained on the mechanisms underlying metastasis formation and the role of aberrant glycosylation within. Mucin-1 and Galectin were recognized as key players in glycosylation. Interestingly, aberrant carbohydrate structures seem to support the development of brain metastasis in breast cancer patients, as changes in glycosylation structures facilitate an overcoming of blood-brain barrier. Changes in the gene expression of glycosyltransferases are the leading cause for a modification of carbohydrate chains, so that also altered gene expression plays a role for glycosylation. In consequence, glycosylation and changes within can be useful for cancer diagnosis, determination of tumour stage and prognosis, but can as well be targets for therapeutic strategies. Thus, further research on this topic would worth wile for cancer combating.

Squamous cell lung carcinoma presenting as melena: a case report and review of the literature

Directory of Open Access Journals (Sweden)

Ibrahim Azar

2017-10-01

Full Text Available Lung cancer has a predilection to widely metastasize to the liver, bone, brain and adrenal glands. Metastasis of primary lung tumors to the stomach is infrequent, with only sporadic cases reported. Most cases are asymptomatic and diagnosed post-mortem on autopsy. The incidence of symptomatic gastrointestinal metastases is extremely rare. Herein, we describe a case of gastric metastasis by squamous cell lung carcinoma, presenting as melena and diagnosed by esophagogastroduodenoscopy. To the best of our knowledge, only twenty other cases in the English literature have reported symptomatic gastric metastasis of lung cancer diagnosed by endoscopic biopsy. A brief review of the literature shows gastric metastasis of lung cancer to have a predilection to occur most frequently in male smokers with the most common type of tumor likely to be squamous cell carcinoma.

The development of brain metastasis (BM) in patients with colorectal cancer (CRC) is a rare and late event. We sought to investigate the clinical characteristics, disease course and safety using biologic agents in our patients with CRC who develop brain metastases. A retrospective review of patients with CRC with brain metastases treated at our institution from 01/2005-01/2015 was performed. Survival analysis was performed using the Kaplan-Meier method. Forty patients were included in the analysis. Median age was 55.5 years, 67.5% were males, and 28% had a KRAS mutation. Twenty-four percent were treatment-naive at the time of BM diagnosis. Patients had a median of two brain lesions. Sixty-five percent of the patients were treated with radiotherapy alone, 22.5% had both surgical resection and brain radiotherapy. Median overall survival was 3.2 months after development of BM. Overall survival was longer in patients who received combined modality local therapy compared to patients treated with surgical resection or radiotherapy alone. Patients who received systemic treatment incorporating biologics following development of BM had a median overall survival of 18.6 months. Overall, the administration of biologic agents was safe and well tolerated. In summary, BM is an uncommon and late event in the natural history of metastatic CRC. The ability to deliver combined-modality local brain therapy as well as availability of more systemic therapy options appear to lead to improved outcomes.

Full Text Available Background and objective Cancer metastasis is not only the malignant marker and characteristics, but also the main cause of failure to cure and lose their life in the patients with lung cancer. Lung cancer metastasis has organ-specific characteristics. The most common sites of lung cancer metastasis are mediastinal lymph node, brain, bone, liver and adrenal gland. The aim of this study is to screen and establish lung cancer cell model with organ-specific metastasis potential with human high-metastatic large cell lung cancer cell line L9981 established by our laboratory previously, and to provide cell models for studying the mechanisms and signal regulation of organ-specific metastasis of lung cancer. Materials and methods The parent lung cancer cell line, L9981-Luc, was inoculated in the armpit of nude mice. The live animal imaging system, IVIS-200, was used to detect the lung cancer organ-specific metastasis every week. When the organ-specific metastasis were established, the nude mices bearing the lung cancer were sacrificed when they became moribund. Under sterile conditions, the organs (mediastinal lymph nodes, lung, spinal column and brain with lung cancer organ-specific metastasis were removed and the metastasized nodules were dissected free of connective tissue and blood clots, and rinsed twice with medium. The metastasized nodules were finely minced using sterile scalpel blades in medium, and the cells were seeded in tissue culture dishes. Then, the cells with organ-specific metastasis potential were reinoculated into the armpit of nude mice, respectively. This processes were repeated to establish the organ-specific metastatic sublines of L9981-Luc cell line more than 10 times. Finally, the organ-specific metastasis sublines of L9981-Luc were screened and established, which the four cell lines have the characteristics only metastasized to brian, lung, bone and mediastinal lymph node.

Since breast cancer is frequently associated with bone metastasis, bone scintigraphies have been performed to determine pre-operative staging and to survey postoperative bone metastasis. The sternum, in particular, is a site at which is difficult to differentiate between benign bone disease and bone metastasis, because of varied uptake and wide individual variations. In this study, chronological bone images were scintigraphied in six cases with solitary sternal metastasis and three cases with benign bone disease including two fracture cases and one arthritis case. On bone scintigrams in which solitary sternal metastasis appeared, increased uptake was found in five cases, and photon deficiency was observed in one case. During follow-up scintigraphies, abnormal accumulations, such as hot spots and cold lesions, increased in the bone metastasis while abnormal uptake disappeared or was unchanged in the benign bone disease cases. On CT, four cases showed osteolytic change, and one exhibited osteosclerotic change. These findings indicate that sternal metastasis usually shows osteolytic change, even if a hot lesion is recognized on bone scintigraphy. In solitary sternal metastasis, for which early diagnosis is difficult, both an integrated diagnosis using other imaging techniques and chronological bone scintigraphy are important. (author)

Angiosarcoma of the Thyroid and Regional Lymph Node Metastasis

Lutfi Dogan

2013-10-01

Full Text Available Thyroid angiosarcomas are typically infiltrative and large tumors with very similar clinical findings of anaplastic carcinoma of thyroid. Early hematogenous metastasis is very frequent, but regional lymph node metastasis is quite rare. We present a case of angiosarcoma of the thyroid gland in a 68 years old man with regional lymph node metastasis. Total thyroidectomy with right modified radical neck dissection was applied. Four out of 19 lymph nodes dissected were seen to contain metastasis. Metastatic tumor was composed of sarcomatous areas containing large numbers of blood filled clefts. There after the surgery PET-CT was performed and multiple metastatic involvements were reported. Thyroid angiosarcomas are completely different tumors from angiomatoid anaplastic carcinomas. Longer survival with these tumors is only possible with agressive surgery and in case of regional LN metastasis, neck dissection should be done.

Differential diagnosis between spinal metastasis and infectious spondylodiscitis is one of the occasional challenges in daily clinical practice. We encountered an unusual case of spinal metastasis in a 75-year-old female breast cancer patient that mimicked infectious spondylodiscitis. Magnetic resonance imaging (MRI) showed diffuse bone marrow infiltrations with paraspinal soft tissue infiltrative changes in 5 contiguous cervical vertebrae without significant compression fracture or cortical destruction. These MRI findings made it difficult to differentiate between spinal metastasis and infectious spondylodiscitis. Infectious spondylodiscitis such as tuberculous spondylodiscitis was regarded as the more appropriate diagnosis due to the continuous involvement of > 5 cervical vertebrae. The patient's clinical presentation also supported the presumptive diagnosis of infectious spondylodiscitis rather than spinal metastasis. Intravenous antibiotics were administered, but clinical symptoms worsened despite treatment. After pathologic confirmation by computed tomography-guided biopsy, we were able to confirm a final diagnosis of spinal metastasis

Objective: To evaluate the efficacy of CT-guided percutaneous acetic acid injection (PAI) for liver metastasis. Methods: Thirty-five cases (40 lesions) with liver metastasis were treated with PAI. 4-10 ml of 30% acetic acid with 1 ml contrast media was injected into every lesion. PAI was performed twice a week, and repeated for 2 to 3 weeks. Results: The tumors shrunk in 23 lesions, and remained unchanged in 12 lesions. The efficiency was 87.5%. All cases were followed up for 3 months to 3 years. One year survival rates was 62.9% (22 cases), 2 years 40.0% (14 cases), and 3 years 22.9% (8 cases). Conclusion: PAI was an effective therapy for liver metastasis

To determine the perfusion-sensitive characteristics of cerebral dural metastases and compare them with the data on meningiomas. Twenty-two patients presenting with dural tumor underwent conventional and dynamic susceptibility-contrast MR imaging: breast carcinoma metastases, two patients; colorectal carcinoma metastasis, one patient; lung carcinoma metastasis, one patient; Merkel carcinoma metastasis, one patient; lymphoma, one patient; meningiomas, 16 patients. The imaging characteristics were analyzed using conventional MR imaging. The cerebral blood volume (CBV) maps were obtained for each patient and the relative CBV (rCBV) in different areas was calculated using the ratio between the CBV in the pathological area (CBVp) and in the contralateral white matter (CBVn). The differentiation between a meningioma and a dural metastasis can be difficult using conventional MR imaging. The rCBVs of lung carcinoma metastasis (1 case: 1.26), lymphoma (1 case: 1.29), breast carcinoma metastasis (2 cases: 1.50,1.56) and rectal carcinoma metastasis (1 case: 3.34) were significantly lower than that of meningiomas (16 cases: mean rCBV = 8.97±4.34, range 4-18). Merkel carcinoma metastasis (1 case: 7.56) showed an elevated rCBV, not different from that of meningiomas. Dural metastases are sometimes indistinguishable from meningiomas using conventional MR imaging. rCBV mapping can provide additional information by demonstrating a low rCBV which may suggest the diagnosis of metastasis.

Gamma knife radiosurgery (GKS) is generally an effective and safe treatment for brain metastases. We report 3 rare complicated cases after GKS due to radiation injury including image findings. Case 1: A 58-year-old man received whole brain radiation therapy for right occipital brain metastasis from lung cancer. However, local recurrence was noted and GKS was carried out 5 months later (size 28 mm, marginal dose 23 Gy (50% isodose)). Four years later, a cyst appeared and the patient developed apraxia and visual disturbance. Surgery was performed and the histopathology showed necrosis. Case 2: A 51-year-old woman received GKS for 4 brain metastases from breast cancer. The right occipital lobe lesion was treated with marginal dose of 18 Gy (size 24 mm, 50% isodose). Thirty-one months later, she developed left homonymous hemianopsia and MR imaging and CT scan showed intracerebral hemorrhage with cyst formation. An operation was performed and the histology revealed necrosis. Case 3: A 37-year-old man received GKS for left temporal brain metastasis from lung cancer (size 14 mm, marginal dose 23 Gy (50% isodose)). Twelve months later, the lesion increased in size again, so we carried out a second GKS on the same lesion (size 15 mm, marginal dose 23 Gy (50% isodose)). Thirty-five months later, massive peritumoral edema appeared and the patient developed left oculomotor palsy. An emergency operation was performed and the histopathological diagnosis was cavernous malformation that was thought to be induced by radiosurgery. Although the incidence is low, rare complications associated with radiation therapy can also occur by radiosurgery. (author)

1982-01-01

A retrospective analysis was done of 106 patients who received radiation therapy for brain metastasis. Dexamethasone therapy was instituted in 97 patients. Peptic ulcer disease developed in 5 of 89 patients (5.6 percent) who received a dosage of at least 12 mg a day, but did not occur in patients who received a lower dose or in those who did not receive steroids. The interval between institution of dexamethasone therapy and the development of peptic ulcer disease ranged from three to nine weeks. Two patients had perforated ulcers, one of whom required surgical resection. Peptic ulcer disease contributed to the general deterioration and death of three of the five patients. Overall, in 14 of the 89 patients (15.7 percent) a complication of steroid therapy developed in the form of peptic ulcer disease, steroid myopathy or diabetes mellitus (or a combination of these)

Full Text Available Infestation of the living tissues of the eye, ocular adnexae or orbit by larvae of flies of the order Diptera is known as ophthalmomyiasis. Ophthalmomyiasis externa is a limited superficial infestation of external ocular structures such as conjunctiva and adnexae. A case of follicular carcinoma thyroid with orbital metastasis presenting as ophthalmomyiasis externa is reported. The patient presented with foul smelling ulcers of the medial and lateral orbital walls of the right eye extending into the lids and nose, teeming with maggots. Computerized Tomography (CT showed widespread bone destruction with extension into surrounding sinuses. Over 200 maggots were manually removed after immobilisation with turpentine oil instillation. Entomological examination showed it to be a case of accidental myiasis caused by the common housefly Musca domestica. The patient was managed conservatively and the ulcer cavities filled up with healthy granulation tissue. This case is presented on account of its rarity.

Introduction: The use of radioguided occult lesion localization prior to surgical excision is increasing, mainly due to the development of new probes and the use of PET-CT. Case report: A 70-year-old male who presented with a metastatic lesion in his liver from a choroidal melanoma. This was located using PET-CT and subsequently located with a low-energy intraoperative gamma probe during the laparotomy. Conclusion: The present case shows that it is possible to excise a hepatic metastasis utilizing the principles of radioguided surgery, even in centers without access to high energy probes. (author)

Primary intraosseous carcinoma arising from odontogenic keratocyst with parotid lymph node metastasis. A case report

2007-01-01

Full Text Available Squamous cell carcinoma (SCC arising from odontogenic cyst lining is rare. The exact incidence of carcinoma arising in odontogenic cyst is unknown, but it is estimated to vary between 1 and 2/1000. The pathogenesis is unknown, but a long-standing inflammation and continuous intracystic pressure have been suggested as possible causative factors. Metastasis from these lesions is not common (< 20%, and most of the carcinomas are moderately to well differentiated. To qualify as a primary intraosseous carcinoma, there must be no initial connection with the oral mucosa, overlying skin, or antral or nasal mucosa. This paper presents a case of primary intraosseous carcinoma arising from odontogenic keratocyst in the anterior mandible with metastasis to left parotid lymph nodes.

Role of the Blood-Brain Barrier in the Formation of Brain Metastases

Directory of Open Access Journals (Sweden)

István A. Krizbai

2013-01-01

Full Text Available The majority of brain metastases originate from lung cancer, breast cancer and malignant melanoma. In order to reach the brain, parenchyma metastatic cells have to transmigrate through the endothelial cell layer of brain capillaries, which forms the morphological basis of the blood-brain barrier (BBB. The BBB has a dual role in brain metastasis formation: it forms a tight barrier protecting the central nervous system from entering cancer cells, but it is also actively involved in protecting metastatic cells during extravasation and proliferation in the brain. The mechanisms of interaction of cancer cells and cerebral endothelial cells are largely uncharacterized. Here, we provide a comprehensive review on our current knowledge about the role of junctional and adhesion molecules, soluble factors, proteolytic enzymes and signaling pathways mediating the attachment of tumor cells to brain endothelial cells and the transendothelial migration of metastatic cells. Since brain metastases represent a great therapeutic challenge, it is indispensable to understand the mechanisms of the interaction of tumor cells with the BBB in order to find targets of prevention of brain metastasis formation.

Lymph Node Metastasis after a Soft Tissue Sarcoma of the Leg: A Case Report and a Review of the Literature

2013-01-01

Full Text Available Introduction. Soft tissue sarcomas (STSs represent 1 percent of all adult malignancies and sarcomas only rarely spread to the regional lymph nodes. Case Presentation. We present a case of a woman with a dermatofibrosarcoma protuberans and a sarcoma not therwise specified of the lower extremity. The patient had no distant metastasis during follow-up, but did develop a regional lymph nodemetastasis (RLNM in the groin. We reviewed the literature about RLNM in STSs. Discussion. Reviewing the literature we see that within specific histological types RLNM occurs as often as distant metastasis. Furthermore RLNM occurs in over 10% for specific histological types and in 24% of all patients with a soft tissue sarcoma of the lower extremity. Except for radical lymphadenectomy with a 5-year survival rate of 46% there is no appropriate treatment. Conclusion. The risk for a RLNM in certain histological types and anatomical locations might transcend the risk for a distant lung metastasis.

Whole brain radiotherapy (WBRT) is the most widely used treatment for brain metastasis (BM), especially for patients with multiple intracranial lesions. The purpose of this study was to examine the efficacy of systemic treatments following WBRT in breast cancer patients with BM who had different clinical characteristics, based on the classification of the Radiation Therapy Oncology Group recursive partitioning analysis (RPA) and the breast cancer-specific Graded Prognostic Assessment (Breast-GPA). One hundred and one breast cancer patients with BM treated between 2006 and 2010 were analyzed. The median interval between breast cancer diagnosis and identification of BM in the triple-negative patients was shorter than in the luminal A subtype (26 vs. 36 months, respectively; P = 0.021). Univariate analysis indicated that age at BM diagnosis, Karnofsky performance status/recursive partitioning analysis (KPS/RPA) classes, number of BMs, primary tumor control, extracranial metastases and systemic treatment following WBRT were significant prognostic factors for overall survival (OS) (P RPA classes and systemic treatments following WBRT remained the significant prognostic factors for OS. For RPA class I, the median survival with and without systemic treatments following WBRT was 25 and 22 months, respectively (P = 0.819), while for RPA class II/III systemic treatments significantly improved OS from 7 and 2 months to 11 and 5 months, respectively (P RPA class II/III patients.

Pelvic lymph node (LN) metastasis is a well-recognized route of prostate cancer spread. However, the relationship between topography and pathologic features of primary prostatic cancers and patterns of pelvic LN metastasis has not been well studied. We reviewed original slides of radical prostatectomies and pelvic LN dissections from 125 patients with LN metastasis and recorded total # of LN excised / laterality of positive LN, as well as localization, staging parameters, lymphovascular invasion and tumor volume of primary tumors. LN Quantity and Distribution 14.6 (mean) and 13 (median) LN were resected. 76 (61%), 33 (26%) and 16 (13%) cases had 1, 2 and > 2 positive LN, while 58, 44 and 20 cases had LN metastasis on the right (R), left (L), and bilaterally. Pathologic Features 86% (108/125) and 37% (46/125) demonstrated extraprostatic extension and seminal vesicle invasion, while 64% showed lymphovascular invasion. Mean and median total tumor volume was 6.39 and 3.92 cc, with ≥ 50% and ≥ 90% Gleason patterns 4/5 in 105 (84%) and 73 (58%) cases, respectively. Correlation with Dominant Tumor Location Dominant lesions on RP: 50 R lobe, 44 L lobe, 31 bilateral. 15/50 (30%) R lobe and 18/44 (41%) L lobe dominant tumors had LN metastasis on the contralateral side. Only 4% (5/125) of cases were associated with anterior dominant tumors. 30–40% of LN metastases occur contralateral to the dominant tumor. LN metastasis is overwhelmingly associated with high grade, high stage and large volume disease. LN positivity is rarely associated with anterior dominant tumors. PMID:21107093

Background Leptomeningeal metastasis, which results from metastasis of tumors to the arachnoid and pia mater, can lead to the dissemination of tumor cells throughout the subarachnoid space via the cerebral spinal fluid, and frequently with a poor prognosis. The primary tumor in adults is most often breast cancer, lung cancer, or melanoma. Although leptomeningeal metastasis due to cholangiocarcinoma has been reported, to the best of our knowledge there is no cytologically confirmed report of l...

Prostate cancer is the second most common cancer in man. It commonly presents with urinary symptoms, bone pain, or diagnosed with elevated prostate-specific antigen.(PSA) levels. Correct staging and early diagnosis of recurrence by a precise imaging tool are the keys for optimum management. Molecular imaging of prostate cancer with Ga-68 prostate-specific membrane antigen.(PSMA), positron emission tomography-computed tomography.(PET-CT) has recently received significant attention and frequently used with a signature to prostate cancer-specific remark. However, this case will highlight the more cautious use of it. A-72-year-old male treated earlier for synchronous double malignancy.(invasive papillary urothelial carcinoma right ureter and carcinoma prostate) presented with rising PSA.(0.51.ng/ml) and referred for Ga-68 PSMA PET-CT, which showed a positive enlarged left supraclavicular lymph node. Lymph node biopsy microscopic and immunohistochemistry examination revealed metastatic carcinoma favoring urothelial origin. Specificity of PSMA scan to prostate cancer has been seen to be compromised in a certain situation mostly due to neoangiogenesis, and false positives emerged in renal cell cancer, differentiated thyroid cancer, glioblastoma, breast cancer brain metastasis, and paravertebral schwannomas. Understanding the causes of false positive will further enhance the confidence of interpretating PSMA scans

Purpose: Prior statistical models attempted to identify risk factors for time to distant brain failure (DBF) or time to salvage whole-brain radiation therapy (WBRT) to predict the benefit of early WBRT versus stereotactic radiosurgery (SRS) alone. We introduce a novel clinical metric, brain metastasis velocity (BMV), for predicting clinical outcomes after initial DBF following upfront SRS alone. Methods and Materials: BMV was defined as the cumulative number of new brain metastases that developed over time since first SRS in years. Patients were classified by BMV into low-, intermediate-, and high-risk groups, consisting of <4, 4 to 13, and >13 new metastases per year, respectively. Histology, number of metastases at the time of first SRS, and systemic disease status were assessed for effect on BMV. Results: Of 737 patients treated at our institution with upfront SRS without WBRT, 286 had ≥1 DBF event. A lower BMV predicted for improved overall survival (OS) following initial DBF (log-rank P<.0001). Median OS for the low, intermediate, and high BMV groups was 12.4 months (95% confidence interval [CI], 10.4-16.9 months), 8.2 months (95% CI, 5.0-9.7 months), and 4.3 months (95% CI, 2.6-6.7 months), respectively. Multivariate analysis showed that BMV remained the dominant predictor of OS, with a hazard ratio of 2.75 for the high BMV group (95% CI, 1.94-3.89; P<.0001) and a hazard ratio of 1.65 for the intermediate BMV group (95% CI, 1.18-2.30; P<.004). A lower BMV was associated with decreased rates of salvage WBRT (P=.02) and neurologic death (P=.008). Factors predictive for a higher BMV included ≥2 initial brain metastases (P=.004) and melanoma histology (P=.008). Conclusions: BMV is a novel metric associated with OS, neurologic death, and need for salvage WBRT after initial DBF following upfront SRS alone.

Conclusion: To our knowledge, this is the first reported case of metachronously developed, isolated omental metastasis of an initially T1 clear-cell RCC. Constitutional symptoms, despite a long interval since nephrectomy, should raise the possibility of a paraneoplastic syndrome being associated with metastatic RCC. Morphological and molecular imaging studies together with histopathological documentation will be diagnostic.

Full Text Available Aim: Brain abscess still poses a public health challenge in spite of the advent of modern neurosurgical techniques and antibiotics. Here, we present our surgical experiences and ultimate outcome in the management of brain abscess. Methods: Totally, 162 patients with proved brain abscess who underwent surgical treatment were included in this study. The prospectively recorded data of surgical management of brain abscess and the ultimate outcome (by Glasgow outcome scale were studied retrospectively. Results: Total number of cases was 162, of which 113 were acute pyogenic abscess while 49 were chronic abscess. Among the chronic abscess, 29 were chronic pyogenic abscess, 14 were tubercular, 3 aspergillus, and 3 abscesses were in malignant brain metastases. In acute cases, common clinical features were headache, fever, vomiting, focal deficit and seizure. In chronic abscesses, common clinical features were mild to moderate headache and progressive focal deficit. Seventy-three (45.06% patients had adjacent localized sinus, middle ear or cranial infection. The common predisposing factors included postneurosurgery, postpenetrating injury to brain, chronic suppurative otitis media, and congenital heart disease, infective endocarditis, sinusitis and sub optimum immuno-status. Frontal lobe involved in 30.2% cases, temporal lobe is next to involved. Single time burr hole aspiration in 111 (68.5% cases, two or more times burr hole aspiration were done in 34 (21% cases.

The lung large-cell neuroendocrine carcinoma (LCNEC) is a very rare aggressive neuroendocrine tumor with a high propensity to metastasize and very poor prognosis. We report an atypical presentation of lung LCNEC was diagnosed from a metastatic nodule on the breast. Our patient is a 59-years-old woman that presented in March 2014 nonproductive cough. A CT scan showed multiple brain, lung, adrenal gland and liver secondary lesions; moreover, it revealed a breast right nodule near the chest measuring 1.8 cm. The breast nodule and lung lesions were biopsied and their histology and molecular diagnosis were LCNEC of the lung. To our knowledge, this is the first documented case of breast metastasis from LCNEC of the lung. Furthermore, breast metastasis from extramammary malignancy is uncommon and its diagnosis is difficult but important for proper management and prediction of prognosis. Therefore, a careful clinical history with a thorough clinical examination is needed to make the correct diagnosis. Moreover, metastasis to the breast should be considered in any patient with a known primary malignant tumor history who presents with a breast lump. Anyhow, pathological examination should be performed to differentiate the primary breast cancer from metastatic tumor. Therefore, an accurate diagnosis of breast metastases may not only avoid unnecessary breast resection, more importantly it is crucial to determine an appropriate and systemic treatment. © 2015 John Wiley & Sons Ltd.

Full Text Available Objectives: This study aimed to raise radiologists’ awareness of skeletal muscle metastases (SMM in renal cell carcinoma (RCC cases and to clarify their imaging appearance. Methods: A retrospective analysis was undertaken of 21 patients between 44–75 years old with 72 SMM treated from January 1990 to May 2009 at the MD Anderson Cancer Center in Houston, Texas, USA. Additionally, 37 patients with 44 SMM from a literature review were analysed. Results: Among the 21 patients, the majority of SMM were asymptomatic and detected via computed tomography (CT. Mean metastasis size was 18.3 mm and the most common site was the trunk muscles (83.3%. The interval between discovery of the primary tumour and metastasis detection ranged up to 234 months. Peripheral enhancement (47.1% was the most common post-contrast CT pattern and non-contrasted CT lesions were often isodense. Magnetic resonance imaging (MRI characteristics were varied. Five lesions with available T1-weighted pre-contrast images were hyperintense to the surrounding muscle. Other organ metastases were present in 20 patients. Of the 44 SMM reported in the literature, the majority were symptomatic. Average metastasis size was 53.4 mm and only 20.5% of SMM were in trunk muscles. The average interval between tumour discovery and metastasis detection was 101 months. Other organ metastases were recorded in 17 out of 29 patients. Conclusion: SMM should always be considered in patients with RCC, even well after primary treatment. SMM from RCC may be invisible on CT without intravenous contrast; contrast-enhanced studies are therefore recommended. SMM are often hyperintense to the surrounding muscle on T1-weighted MRI scans.

Whereas extensive research has explored the effect of environmental factors on the etiology of specific cancers, the influence of exposures such as smoking on risk of site-specific metastasis is unknown. We investigated the association of cigarette smoking with lung metastasis in esophageal cancer. We conducted a case-control study of esophageal cancer patients from two centers, comparing cases with lung metastases to controls without lung metastases. Information was gathered from medical records on smoking history, imaging results, site(s) of metastasis, and other patient and tumor characteristics. We used logistic regression to assess association. We identified 354 esophageal cancer cases; smoking status was known in 289 (82%). Among patients with lung metastases, 73.6% (39 of 53) were ever smokers, versus 47.8% (144 of 301) of patients without lung metastases [P=0.001; summary odds ratio (OR), 2.52; 95% confidence interval (95% CI), 1.17-5.45; stratified by histology]. Smoking was associated with a nonsignificant increased adjusted odds of lung metastasis (OR, 1.89; 95% CI, 0.80-4.46). Upper esophageal subsite (OR, 4.71; 95% CI, 1.20-18.5), but not histology (squamous OR 0.65,95% CI 0.27-1.60), was associated with lung metastasis. Compared with the combined never/unknown smoking status group, smoking was associated with a significantly increased odds of lung metastasis (OR, 2.35; 95% CI, 1.11-4.97). There was no association between liver metastasis and smoking (OR, 0.88; 95% CI, 0.42-1.83). Smoking is associated with increased odds of lung metastasis from esophageal cancer, and this relationship seems to be site specific. Future studies are needed to determine whether smoking affects the tumor cell or the site of metastasis, and whether this changes the survival outcome.

SU-E-QI-21: Iodinated Contrast Agent Time Course In Human Brain Metastasis: A Study For Stereotactic Synchrotron Radiotherapy Clinical Trials

Purpose: Synchrotron stereotactic radiotherapy (SSRT) is an innovative treatment combining the selective accumulation of heavy elements in tumors with stereotactic irradiations using monochromatic medium energy x-rays from a synchrotron source. Phase I/II clinical trials on brain metastasis are underway using venous infusion of iodinated contrast agents. The radiation dose enhancement depends on the amount of iodine in the tumor and its time course. In the present study, the reproducibility of iodine concentrations between the CT planning scan day (Day 0) and the treatment day (Day 10) was assessed in order to predict dose errors. Methods: For each of days 0 and 10, three patients received a biphasic intravenous injection of iodinated contrast agent (40 ml, 4 ml/s, followed by 160 ml, 0.5 ml/s) in order to ensure stable intra-tumoral amounts of iodine during the treatment. Two volumetric CT scans (before and after iodine injection) and a multi-slice dynamic CT of the brain were performed using conventional radiotherapy CT (Day 0) or quantitative synchrotron radiation CT (Day 10). A 3D rigid registration was processed between images. The absolute and relative differences of absolute iodine concentrations and their corresponding dose errors were evaluated in the GTV and PTV used for treatment planning. Results: The differences in iodine concentrations remained within the standard deviation limits. The 3D absolute differences followed a normal distribution centered at zero mg/ml with a variance (∼1 mg/ml) which is related to the image noise. Conclusion: The results suggest that dose errors depend only on the image noise. This study shows that stable amounts of iodine are achievable in brain metastasis for SSRT treatment in a 10 days interval.

Full Text Available Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis. Our patient, a 51-year old woman presented with breast lump and history of post-menopausal bleeding. Upon further workup, the patient was diagnosed with cervical cancer. The mammogram and ultrasound of the breast showed multiple lumps within the breast. Histopathology of the breast mass showed metastatic deposit in the breast from cervical cancer. The patient was treated with radiation therapy to the cervix along with concurrent chemotherapy for local control of pain. After completion of local treatment, she started systemic chemotherapy, however she developed health-care associated pneumonia and subdural hematoma leading to deterioration in her performance status. The patient opted for hospice care and died 2 months later. In this report, we will review the presentation of the 38 cases reported in literature and the imaging and histopathologic findings of metastatic deposits to the breast.

Metastasis from a malignant tumor to the palatine tonsils is rare, accounting for only 0.8% of all tonsillar tumors, with only 100 cases reported in the English-language literature. Various malignant lung carcinomas may metastasize to the tonsils. A few cases of tonsillar metastasis from neuroendocrine lung carcinoma have been reported. A 67-year-old female underwent a right tonsillectomy because of a sore throat and an enlarged right tonsil. The postoperative pathology showed right tonsillar small cell neuroendocrine carcinoma (SCNC). Fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) demonstrated metabolic activity in the lower lobe of the right lung. In addition, hypermetabolic foci were noted in the lymph nodes of the right neck and mediastinum. A needle biopsy of the pulmonary mass showed SCNC. The patient received chemotherapy and died of multiple distant metastases after 6 months. This is the first report using PET/CT to evaluate tonsillar metastasis from lung SCNC

Full Text Available The susceptibility of brain to secondary formation from lung cancer primaries is a well-known phenomenon. In contrast, the molecular basis for invasion and metastasis to the brain is largely unknown. In the present study, 31 brain metastases that originated from primary lung carcinomas were analyzed regarding over expression of Dishevelled-1 (DVL1, Dishevelled-3 (DVL3, E-cadherin (CDH1 and beta-catenin (CTNNB1. Protein expressions and localizations were analyzed by immunohistochemistry. Genetic alterations of E-cadherin were tested by polymerase chain reaction (PCR/loss of heterozygosity (LOH. Heteroduplex was used to investigate mutations in beta-catenin. DVL1 and DVL3 showed over expression in brain metastasis in 87.1% and 90.3% of samples respectively. Nuclear staining was observed in 54.8% of cases for DVL1 and 53.3% for DVL3. The main effector of the Wnt signaling, beta-catenin, was up-regulated in 56%, and transferred to the nucleus in 36% of metastases. When DVL1 and DVL3 were up-regulated the number of cases with nuclear beta-catenin significantly increased (p = 0.0001. Down-regulation of E-cadherin was observed in 80% of samples. Genetic analysis showed 36% of samples with LOH of the CDH1. In comparison to other lung cancer pathologies, the diagnoses adenocarcinoma and small cell lung cancer (SCLC were significantly associated to CDH1 LOH (p = 0.001. Microsatellite instability was detected in one metastasis from adenocarcinoma. Exon 3 of beta-catenin was not targeted. Altered expression of Dishevelled-1, Dishevelled-3, E-cadherin and beta-catenin were present in brain metastases which indicates that Wnt signaling is important and may contribute to better understanding of genetic profile conditioning lung cancer metastasis to the brain.

AIM: To identify the prognostic factors with regard to survival for patients with brain metastasis from primary tumors of the gastrointestinal tract.METHODS: Nine hundred and sixteen patients with brain metastases, treated with whole brain radiation therapy (WBRT) between January 1985 and December 2000 at the Department of Radiation Oncology, University Hospital Freiburg, were analyzed retrospectively.RESULTS: Fifty-seven patients presented with a primary tumor of the gastrointestinal tract (esophagus: n = 0, stomach:n = 10, colorectal: n = 47). Twenty-six patients had a solitary brain metastasis, 31 patients presented with multiple brain metastases. Surgical resection was performed in 25 patients.WBRTwas applied with daily fractions of 2 Gray (Gy) or 3 Gy to a total dose of 50 Gy or 30 Gy, respectively. The interval between diagnoses of the primary tumors and brain metastases was 22.6 mo vs8.0 mo for patients with primary tumors of the colon/rectum vs other primary tumors,respectively (P＜0.01, log-rank). Median overall survival for all patients with brain metastases (n = 916) was 3.4 mo and 3.2 mo for patients with gastrointestinal neoplasms.Patients with gastrointestinal primary tumors presented significantly more often with a solitary brain metastasis than patients with other primary tumors (P＜0.05, log-rank). In patients with gastrointestinal neoplasms (n = 57), the median overall survival was 5.8 mo for patients with solitary brain metastasis vs 2.7 mo for patients with multiple brain metastases (P＜0.01, log-rank). The median overall survival for patients with a Karnofsky performance status (KPS) ≥70was 5.5 mo vs2.1 mo for patients with KPS ＜70 (P＜0.01,log-rank). At multivariate analysis (Cox Model) the performance status and the number of brain metastases were identified as independent prognostic factors for overall survival.CONCLUSION: Brain metastases occur late in the course of gastrointestinal tumors. Pretherapeutic variables like KPS and the

An isolated splenic metastasis is a rare phenomenon noted in advanced stage melanoma. We report the role of radiofrequency (RF) -based splenic-preserving splenectomy in a patient with a solitary splenic metastasis from advanced stage melanoma that was managed with checkpoint inhibitors. We report a case of a 60-year-old man who presented with multiple lung metastases and a solitary splenic metastasis with advanced stage melanoma following excision of primary from his trunk 2.3 years back. Considering the diagnosis of advanced stage melanoma with multiple lung metastases and a solitary splenic metastasis, and its ongoing progressive nature. This case was discussed in the tumour board meeting. A decision was made to commence treatment with immunotherapy in the form of PD-1 inhibitor (programmed cell death 1 receptor) pembrolizumab. Follow-up restaging computer tomography (CT) scan of the abdomen and chest showed a significant reduction in the lung and chest wall lesions, but the splenic lesion remained unchanged. Given the lack of response to treatment in the splenic metastasis and the significant decrease in lung metastases, the multidisciplinary team decided that a partial splenectomy combined with continued immunotherapy treatment would be appropriate as the success of immunotherapy was imminent within the splenic preservation. The postoperative recovery was smooth and the patient was discharged from hospital on the sixth postoperative day with normal platelets and white blood cells. The histopathological analysis of the resected specimen showed a metastatic melanoma with negative margins.At 10-month follow-up after the splenic resection the patient had not experienced further tumour recurrences. Spleen-preserving resection for an isolated, solitary splenic metastasis of melanoma is a feasible approach as it not only preserves the ongoing efficacy of checkpoint inhibitors by preserving the physiological T cell milieu, but the immunomodulation properties of RF can

Full Text Available Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.

Bevacizumab blocks the effects of vascular endothelial growth factor in leakage-prone capillaries and has been suggested as a new treatment for cerebral radiation edema and necrosis. CyberKnife is a new, frameless stereotactic radiosurgery system. This work investigated the safety and efficacy of CyberKnife followed by early bevacizumab treatment for brain metastasis with extensive cerebral edema. The eligibility criteria of the patients selected for radiosurgery followed by early use of adjuvant bevacizumab treatment were: (1) brain tumors from metastasis with one solitary brain lesion and symptomatic extensive cerebral edema; (2) >18 years of age; (3) the patient refused surgery due to the physical conditions and the risk of surgery; (4) no contraindications for bevacizumab. (5) bevacizumab was applied for a minimum of 2 injections and a maximum of 6 injections with a 2-week interval between treatments, beginning within 2 weeks of the CyberKnife therapy; (6) Karnofsky performance status (KPS) ≥30. Tumor size and edema were monitored by magnetic resonance imaging (MRI). Dexamethasone dosage, KPS, adverse event occurrence and associated clinical outcomes were also recorded. Eight patients were accrued for this new treatment. Radiation dose ranged from 20 to 33 Gy in one to five sessions, prescribed to the 61-71 % isodose line. Bevacizumab therapy was administered 3-10 days after completion of CyberKnife treatment for a minimum of two cycles (5 mg/kg, at 2-week intervals). MRI revealed average reductions of 55.8 % (post-gadolinium) and 63.4 % (T2/FLAIR). Seven patients showed significant clinical neurological improvements. Dexamethasone was reduced in all patients, with five successfully discontinuing dexamethasone treatment 4 weeks after bevacizumab initiation. Hypertension, a bevacizumab-related adverse event, occurred in one patient. After 3-8 months, all patients studied were alive and primary brain metastases were under control, 2 developed new brain

Thyroid cancer is usually, relatively hypofunctional; most patients with thyroid cancer are clinically euthyroid. The combination of thyroid cancer and thyrotoxicosis is not common. We herein, report a case of follicular thyroid cancer with hyperfunctioning metastasis in a 43-year-old woman who presented with thyrotoxicosis, a cold right thyroid nodule, and low I-131 uptake at the thyroid bed. An additional total body scan with I-131 revealed a large radioiodine avid osteolytic bone metastasis with soft tissue masses and liver metastasis. The patient received treatment with total thyroidectomy, methimazole, and I-131 at a cumulative dose of 600 mCi along with recombinant human thyroid-stimulating hormone before the first I-131 treatment and palliative radiation. The patient had normal liver function test and experienced a mild degree of bone marrow suppression after I-131. At the 2-year follow-up, the patient was still alive with the progression of bone metastases but was doing well with less severe thyrotoxicosis, good ambulation, and an Eastern Cooperative Oncology Group performance status of 2. Clinicians should be aware of the unusual concurrent presentation of thyrotoxicosis and thyroid cancer, a differential diagnosis in patients with thyrotoxicosis and low or normal radioiodine uptake over the neck and also potential pitfalls during radionuclide treatment

Background Gastrointestinal stromal tumors are CD117 (C Kit) positive mesenchymal neoplasms, that may arise anywhere in the gastrointestinal tract. Their current therapy is imatinib mesylate before or after surgery. Case presentation We describe a case of 17-year-old female with metastasis to the cervix uteri of a primary mesenteric gastrointestinal tumor. Conclusion Surgery remains the mainstay of known curative treatment. The manifestations of GIST are not restricted to the typical locations within the bowel; may have very unusual metastatic sites or infiltrations per continuitatem. PMID:18045506

PURPOSE: Recent randomized trials comparing resection of single brain metastasis (BM) in selected patients (pts) followed by whole brain radiotherapy (WBRT) to WBRT alone demonstrated statistically significant survival advantage for surgery (Patchell, 1990 and Noordijk, 1994). This multi-institutional retrospective study was performed in similar pts who were treated with RS and WBRT to provide a baseline for comparison for a future randomized trial. MATERIALS AND METHODS: The RS databases of four institutions were reviewed to identify all pts who met the following criteria: single BM; age > 18; surgically resectable lesion; independently functional (KPS {>=} 70); non-radiosensitive histology (small cell, lymphoma, myeloma, germ cell excluded); no prior cranial surgery or WBRT. 122 of 533 pts with BM treated with RS met these criteria. Pts were categorized by: (a) status of the primary: 'absent' = complete resection, 26 pts; 'controlled' locally controlled with radiotherapy or chemotherapy, 70 pts; 'under treatment' = undergoing radiotherapy, 15 pts; 'active' = no definitive or successful treatment of the primary, 11 pts; (b) status of non-CNS metastasis: present=64 pts, absent=58 pts; (c) age: median=61, range 23-83; (d) KPS : KPS 70/80/90/100=20/26/44/32 pts; (e) histology: lung=58, melanoma=16, breast=13, renal=12,colon=9, other=10, unknown primary=4; (f) time from primary to BM: median=12 months, range=1-252 months; (g) gender: male=64, female=58; (h) tumor volume: median=2.68 cc, range=0.13-27.2 cc. RS was performed with a linear accelerator based technique (peripheral dose 10-27 Gy, median 17 Gy). WBRT was performed in all but 5 pts who refused it (range 25 - 40 Gy, median 37.5 Gy). RESULTS: The potential median follow-up for all pts is 123 weeks (wks). The overall local response rate is 59% (complete response = 25%, partial response = 34%). In field progression occurred in 17 patients (14%), with overall local control of 86%. Local control was highest for

Selected patients with brain metastases from non-small-cell lung cancer benefit from aggressive treatment. This report describes three patients who developed solitary brain metastases after previous resection of primary adenocarcinoma of the lung. Each underwent surgical resection of their brain metastasis followed by cranial irradiation and remain disease free 10 or more years later. Two patients developed cognitive impairment approximately 8 years after treatment of their brain metastasis, which was felt to be due to their previous brain irradiation. Here we discuss the treatment of solitary brain metastasis, particularly the value of combined method approaches in selected patients and dose-volume considerations

To determine the frequency of tuberculous cervical lymphadenopathy mimicking metastasis from papillary thyroid cancer. Study Design: Case series. Place and Duration of Study: Surgical Unit-I, Ward-3 of Jinnah Postgraduate Medical Centre, Karachi, from March 2005 to March 2010. Methodology: All patients above 12 years of age of either gender diagnosed on investigations as papillary thyroid cancer (PTC) were included in the study. Ultrasound and fine needle aspiration cytology (FNAC), neck of solitary thyroid nodules (STN) and cervical lymph nodes were done. Total thyroidectomy and excision biopsy of cervical lymph nodes was performed, histopathological results were recorded and patients were managed accordingly. Results: A total of 55 patients had PTC and 25 had cervical lymphadenopathy. Eighteen patients of PTC with cervical lymphadenopathy were diagnosed after investigations as cases of tuberculous cervical lymphadenopathy (TCL) initially considered as metastasis from PTC; 5 patients had metastasis from PTC. Two patients proved to be of reactive hyperplasia which initially showed tuberculous cervical lymphadenopathy on FNAC. So 80% patients of cervical lymphadenopathy with PTC were due to benign disease and 20% had metastasis in lymph node due to PTC. Conclusion: PTC with cervical lymphadenopathy due to co-existent tuberculosis is common. Metastasis from PTC in lymph nodes were less common than tuberculous lymphodenitis in this study. Tuberculosis should be considered before deciding for neck dissection in cases of PTC. (author)

Differentiated thyroid cancer is usually associated with an excellent prognosis and indolent course. Distant metastases are rare events at the onset of thyroid cancer. Among these presentations, metastasis to the axillary lymph nodes is even more unusual: only few cases were previously reported in the literature; there has been no report of axillary lymph node metastasis from follicular thyroid carcinoma. Axillary lymph node metastasis generally arises in the context of disseminated disease and carries an ominous prognosis. Here we present a case of axillary lymph node metastasis in the context of disseminated differentiated thyroid cancer. The patient underwent near total thyroidectomy and neck and axillary lymph node dissection. A histopathological diagnosis of poorly differentiated follicular carcinoma with 'signet ring cells' and Hürthle cell features was established. The patient received radioactive iodine therapy and TSH suppression therapy. Subsequently his serum thyroglobulin level decreased to 44.000 ng/ml from over 100.000 ng/ml. Currently there are only few reported cases of axillary node metastases from thyroid cancer, and to our knowledge, this is the first report on axillary lymph node metastasis from follicular thyroid carcinoma. 'Signet ring cell' is a morphologic feature shared by both benign and, more rarely, malignant follicular thyroid neoplasm, and it generally correlates with an arrest in folliculogenesis. Our case is one of the rare 'signet ring cells' carcinomas so far described

Objective: To investigate the ultrasonic image of adrenal metastasis in primary lung cancer. Methods: The ultrasonic imaging characteristics of fourteen patients with adrenal metastasis in primary lung cancer were retrospectively reviewed. In all the cases, US-guided percutaneous biopsy was performed for pathological evaluation during the clinical diagnosis. Results and Conclusion: In ultrasonography the adrenal metastatic tumors were manifested as solitary in all the cases, well-defined in 10 cases, irregularly shaped in 10 cases, hypoechoic in 13 cases, and 1 case showed cystoid structure in the tumor. The maximum diameter of the tumor was 3.0-15.3 cm. 9 cases were metastatic adenocarcinoma. The sonographic appearance of adrenal metastasis in primary lung cancer has its characteristics. Ultrasonography can find adrenal metastalic tumors easily and contribute to diagnosis. (authors)

This article is aimed to retrospect the clinicopathological data of 2 cases of gastric MANENCs. MANEC is a rare biphasic tumor type that is coexistence of dual neuroendocrine and adenocarcinoma differentiation with each composing exceeding 30% volume. Gastric MANEC have just been reported anecdotally in the literature due to their rarity and heterogeneity. According to our study, these neoplasms have 3 different metastasis patterns: only adenocarcinomatous or neuroendocrine carcinoma and both of the 2 components. We first focus on the correlation of metastasis characteristics with prognosis in gastric MANEC, which may be potential implications for the choice of chemotherapy. The 2 cases of patient shared several symptoms: epigastric discomfort, weight loss, hematemesis, or melena. The 2 patients were diagnosis as MANEC based on the identification of histopathological analysis. In case 1, the poor differentiated adenocarcinoma accounted for 30%, the neuroendocrine part account for 70% and both of the 2 components metastasized to the lymph nodes, whereas in case 2, poorly differentiated adenocarcinoma accounted for 70%, the neuroendocrine part for 30% and only the glandular component invaded regional lymph nodes. The first patient underwent laparoscopic radical gastrectomy and underwent adjuvant chemotherapy, combination of cisplatin, and etoposide successfully. The second patient received radical gastronomy, and did not receive any chemotherapy due to general weakness. The first patient is alive with no evidence of recurrence, and the second patient died 6 months after the operation. The assessment of metastatic sites should be a routine pathological practice, which is crucial for clinical decision-making and the selection of management. Copyright © 2017 The Authors.

We report a case of rhabdomyolysis related to S-1 plus oxaliplatin(SOX)therapy for liver metastasis of gastric cancer. A 76- year-old man who had received SOX therapy for metastatic gastric cancer was admitted to our hospital for a chief complaint of fatigue and weakness. He diagnosed with rhabdomyolysis related to SOX therapy because of his symptoms and because his laboratory studies showed significant elevation of his serum creatine kinase(CK)level. The symptoms disappeared and the CK level normalized following large-volume transfusions. Rhabdomyolysis following SOX therapy is a very rare, but severe adverse event. This is the first detailed case report of rhabdomyolysis related to SOX therapy.

Full Text Available Renal cell carcinoma is known to cause metastasis to unusual sites, which can be both synchronous or metachronous. Thyroid gland is a rare site for metastasis, but when it occurs, renal cell carcinoma is the most common primary neoplasm. We report the case of a 81-year-old female patient who had a significant medical history of right clear cell renal carcinoma with adrenal metastasis. She underwent right radical nephrectomy and adrenalectomy followed by radiofrequency ablation of left adrenal metastasis and systemic chemotherapy with sunitinib. Eleven years later, she presented with dysphagia and was found to have distal esophageal adenocarcinoma. On imaging, there was incidental detection of a left renal mass lesion and a right thyroid nodule, which on histopathology and immunohistochemistry were confirmed to be clear cell carcinoma of renal origin.

A nationwide survey was performed to investigate the current patterns of care for brain metastasis (BM) from breast cancer in Japan. A total of 351 survey questionnaires were sent to community or academic breast oncologists who were members of the Japanese Breast Cancer Society as of December 2005. The questionnaire consists of 40 multiple choice questions in eight categories. Of 240 institutions sent survey questionnaires, 161 (67.1%) answered; 60% of institutions answered with '<5' patients with BM every year; almost half (83 of 161) screened for BM in asymptomatic patients; surgical resection was rarely performed, as ∼75% of institutions (118 of 160 institutions) answered 'none or one case of surgery per year'; 27% (41 of 154) preferred stereotactic radiosurgery (SRS) over whole-brain radiotherapy (WBRT) as the initial treatment in all cases, although ∼70% (100 of 154) of them answered 'depend on cases'. The preference for SRS over WBRT mainly depends on the impressions of breast oncologists about both safety (late normal tissue damage and dementia in WBRT) and efficacy (better local control by SRS). Eighty-one percent (117 of 144) of institutions did not limit the number of SRS sessions as far as technically applicable. SRS is widely used as the first choice for BM from breast cancer in Japan. Considerable numbers of Japanese breast oncologists prefer SRS over WBRT as the initial treatment for BM. A randomized trial comparing SRS and WBRT is warranted. (author)

A 73-year-old man presented with a chief complaint of progressive left knee pain for two months. He had a history of total thyroidectomy and central lymph node dissection due to papillary thyroid carcinoma three months ago. MRI images revealed a solid mass in the left patella. A solid mass demonstrated low signal on T1 weighed image, and high signal on T2 weighed image. And whole body bone scan showed focal photon defect in same lesion of left patella. The histologic result of left knee lesion was adenocarcinoma, consistent with metastatic papillary thyroid carcinoma. Although patellar metastasis of papillary thyroid carcinoma is very rare, when knee pain and radiologic abnormality are noted, differential diagnosis of metastasis is necessary

Full Text Available We report a case of isolated iris metastasis from esophageal adenocarcinoma that was successfully managed with local application of stereotactic body radiation therapy (SBRT and adjunctive intravitreal therapy. A 53-year-old man with locally advanced esophageal adenocarcinoma achieved a complete clinical and radiographic response after surgery and chemotherapy. Four months later, he developed headache and decreased vision and was diagnosed with metastasis to the iris by slit-lamp examination. The decrease in vision was secondary to cystoid macular edema. The metastatic tumor and the patient’s symptoms resolved after treatment with SBRT and intravitreal injections of bevacizumab and triamcinolone. We conclude that SBRT combined with intravitreal chemotherapy is an effective and well-tolerated palliative treatment for metastasis of esophageal adenocarcinoma to the iris.

Primary cardiac tumors are extremely rare. By comparison, metastatic involvement of the heart is over 20 times more common and has been reported in autopsy series in up to one in five patients dying of cancer. Cardiac metastasis of chondrosarcoma is absolutely not frequent. In the recent literature, a cardiac metastasis from chondrosarcoma has never been described. We report the case of an 18-year-old man with a diagnosis of cardiac metastasis that originated from a left scapular chondrosarcoma. Chondrosarcoma is a skeletal tumor with various grades of malignancy, rapidly evolving, and with a strong tendency to metastasize, with low responsiveness to chemotherapy. The onset of characteristic systemic symptoms in the late stage of the disease led to the diagnosis of a mass localized in the right atrium. Management and differential diagnosis of infective heart lesions were also very complex in a rapidly evolving life-threatening condition.

An Unusual Presentation of Lung Cancer Metastasis: Perianal Abscess

2014-06-01

Full Text Available Lung cancer is one of the most commonly diagnosed cancers in both men and women. Although the most frequent sites of distant metastasis of lung cancers are the pleura, liver, adrenal glands, skeletal system and brain, perianal region has been rarely reported as a metastasis site. A male patient was admitted to our emergency room with a long standing perianal abscess. During abscess drainage, a mass was noticed at the base of the abscess pouch, and thus a biopsy was taken. Pathologically, it was reported as a metastasis of squamous cell carcinoma, therefore some radiological  investigations and endoscopic procedures were performed to determine the primary focus of cancer. A pulmonary mass was revealed in PET/CT, and was considered as primary tumor. Both primary and metastatic perianal tumors can be rarely presented as an abscess formation. In this situation, a biopsy should be performed from the lesion to avoid misdiagnosis.

ovarian metastasis in CRC was 2.7%, and isolated ovarian metastases occurred in less than half of them. Of 120 women that underwent colectomy alone, eight (6.6% developed ovarian metastasis during two years of follow-up. Only three cased had isolated ovarian metastases. No patient with synchronous or metachronous ovarian metastases from CRC survived five years."n"nConclusion: Isolated ovarian metastases from primary CRC occur with a low frequency and this may partially explain the debate regarding prophylactic oophorectomy at the time of curative resection for primary CRC.

Purpose: This study evaluates the influence of several prognostic factors on overall survival and progression free survival in patients undergoing stereotactic radiosurgery (SRS) for brain metastases. Materials and Methods: Records of 61 coecutive patients with pathologically confirmed extra-cranial malignancies undergoing SRS at Yale University School of Medicine between 12/18/91 and 7/2/96 were reviewed. All patients underwent head frame localization and CT and/or MRI based treatment planning. Outcome was analyzed with respect to age, number of lesions, size of lesions, location of lesions, site and stage of primary tumor, status of primary tumor at time of SRS, history of whole brain radiation therapy (WBRT), surgery, and/or chemotherapy prior to or after SRS, delay in SRS from diagnosis of brain metastases, dose of radiation delivered, and brain metastasis free interval. Both overall survival and progression free survival were analyzed by the Kaplan-Meier method. Tests for statistical significance were performed using the Cox proportional hazards model. Results: Median follow-up was 29 months. 3% ((8(61))) of patients displayed evidence of progressive disease at the site of SRS, and 87% ((53(61))) of patients have died. Overall and progression free survival rates for the entire cohort of patients were 43.8% and 89.5% at 1 year and 11.1% and 71.4% at 2 years, respectively. Patients undergoing SRS for a solitary brain metastasis had a significant improvement in overall survival with 1 year survival rates of 52.6% vs. 32.7% for patients undergoing SRS for more than 1 brain metastasis (p=0.002). Patients who presented with progressive systemic disease at the time of SRS had an inferior overall survival with a 1 year survival rate of 15.4% compared to patients with presumed/known stable disease who had a 1 year survival rate of 51.5%/54.2% (p<0.001). Patients treated for cerebral metastases had a higher progression free survival compared to patients undergoing SRS

Full Text Available Metastatic malignant mesothelioma of the pleura is uncommon at the time of initial diagnosis. The gastrointestinal lumen is rarely found at autopsy in patients with widespread disease. Here, we describe an extremely rare case of isolated duodenal metastasis of sarcomatoid mesothelioma of the pleura in a 73-year-old man, without memory of any direct exposure to asbestos. The possibility of gastrointestinal tract metastasis should be considered in the presence of anemia or positive occult blood test in patients with malignant pleural mesothelioma.

Isolated metachronous splenic metastasis from synchronous colon cancer

Directory of Open Access Journals (Sweden)

Aker Fugen

2006-07-01

Full Text Available Abstract Background Isolated splenic metastases from colorectal cancer are very rare and there are only 13 cases reported in the English literature so far. Most cases are asymptomatic and the diagnosis is usually made by imaging studies during the evaluation of rising CEA level postoperatively. Case presentation A 76-year-old man underwent an extended left hemicolectomy for synchronous colon cancers located at the left flexure and the sigmoid colon. The tumors were staged as IIIC (T3N2M0 clinically and the patient received adjuvant chemotherapy. During the first year follow-up period, the patient remained asymptomatic with normal levels of laboratory tests including CEA measurement. However, a gradually rising CEA level after the 14th postoperative month necessitated further imaging studies including computed tomography of the abdomen which revealed a mass in the spleen that was subsequently confirmed by 18FDG- PET scanning to be an isolated metastasis. The patient underwent splenectomy 17 months after his previous cancer surgery. Histological diagnosis confirmed a metastatic adenocarcinoma with no capsule invasion. After an uneventful postoperative period, the patient has been symptom-free during the one-year of follow-up with normal blood CEA levels, although he did not accept to receive any further adjuvant therapy. To the best of our knowledge, this 14th case of isolated splenic metastasis from colorectal carcinoma is also the first reported case of splenic metastasis demonstrated preoperatively by 18FDG PET-CT fusion scanning which revealed its solitary nature as well. Conclusion Isolated splenic metastasis is a rare finding in the follow-up of colorectal cancer patients and long-term survival can be achieved with splenectomy.

Patients with a primary pure seminoma in the testis who have elevated serum alpha-fetoprotein are rare and should be treated as patients with nonseminomatous germ cell tumors. However, nonpalpable testicular tumors in this condition have never been reported. We describe a case of nonpalpable pure testicular seminoma with elevated serum alpha-fetoprotein presenting retroperitoneal metastasis. A 29-year-old Asian man was referred to our hospital with right flank pain. Computed tomography showed a mass located between his aorta and inferior vena cava, but a testicular tumor was not detected. His serum levels of lactate dehydrogenase, alpha-fetoprotein, and DUPAN-2 were high. Although no tumor or nodule was palpable in his testis, ultrasonography revealed multiple low echoic lesions in his right testicular parenchyma. He was diagnosed with right testicular cancer with retroperitoneal lymph node metastasis and underwent right high orchiectomy. A pathological examination revealed pure seminoma and no nonseminomatous components were found in the specimen. Three courses of induction systemic chemotherapy (cisplatin, etoposide, and bleomycin) normalized his serum alpha-fetoprotein and DUPAN-2 levels. Three additional courses of chemotherapy (etoposide and bleomycin) were performed, and treatment was completed with laparoscopic retroperitoneal lymph node dissection. Pathology of the dissected specimen showed fibrous and necrotic tissue with no viable cells. He is alive without recurrence 54 months after orchiectomy. We report a case of pure testicular seminoma with elevated serum alpha-fetoprotein and DUPAN-2 presenting retroperitoneal metastasis. We recommend an ultrasound examination of bilateral testes when large retroperitoneal tumors are detected in young men, even if a mass is not palpable in the scrotum.

Purpose: Metastasis to the brain from breast cancer remains a significant clinical challenge, and may be targeted with CAR-based immunotherapy. CAR design optimization for solid tumors is crucial due to the absence of truly restricted antigen expression and potential safety concerns with "on-target off-tumor" activity. Here, we have optimized HER2-CAR T cells for the treatment of breast to brain metastases, and determined optimal second-generation CAR design and route of administration for xenograft mouse models of breast metastatic brain tumors, including multifocal and leptomeningeal disease. Experimental Design: HER2-CAR constructs containing either CD28 or 4-1BB intracellular costimulatory signaling domains were compared for functional activity in vitro by measuring cytokine production, T-cell proliferation, and tumor killing capacity. We also evaluated HER2-CAR T cells delivered by intravenous, local intratumoral, or regional intraventricular routes of administration using in vivo human xenograft models of breast cancer that have metastasized to the brain. Results: Here, we have shown that HER2-CARs containing the 4-1BB costimulatory domain confer improved tumor targeting with reduced T-cell exhaustion phenotype and enhanced proliferative capacity compared with HER2-CARs containing the CD28 costimulatory domain. Local intracranial delivery of HER2-CARs showed potent in vivo antitumor activity in orthotopic xenograft models. Importantly, we demonstrated robust antitumor efficacy following regional intraventricular delivery of HER2-CAR T cells for the treatment of multifocal brain metastases and leptomeningeal disease. Conclusions: Our study shows the importance of CAR design in defining an optimized CAR T cell, and highlights intraventricular delivery of HER2-CAR T cells for treating multifocal brain metastases.

Thallium-201 ( 201 TI) brain SPECT, which can represent cellular activity of brain lesions, may provide more useful information in differentiating between benign and malignant brain lesions more so than CT or MRI, that merely represents anatomic changes or breakdown of blood brain barrier. We used 201 TI brain SPECT prospectively to evaluate the utility of 201 TI-indices as an indicator of benign or malignant lesions. We studied 28 patients. There were 13 cases of benign lesions (3: nonspecific benign lesion, 3: meningioma, 2: low grade glioma, 1: tuberculoma, central neurocytoma, hemangioblastoma, radiation necrosis, and choroid plexus papilloma) and 15 cases of malignant lesions (6: glioblastoma multiforme, 5: anaplastic glioma, 2: medulloblastoma, 1: metastasis and lymphoma). In all patients, CT and/or MRI were obtained and then 201 TI brain SPECT was obtained with measuring mean 201 TI index and peak 201 TI index. An unpaired t-test was performed to compare the 201 TI-indices and pathologic diagnoses to evaluate the utility of 201 TI-indices as an indicator of benign or malignant lesions. There were no statistically significant difference in 201 TI-indices between benign and malignant brain lesions (P>0.05). These results demonstrated that we could not use 201 TI indices on brain SPECT alone as an indicator of benign or malignant brain lesions

Full Text Available Carcinoma of the cervix is the most common malignancy among women in India. Although metastatic disease is common, metastasis to breast is rare. A limited number of case reports are published in the world literature. Most of the previous reports of metastatic cervical carcinoma to breast are either autopsy series or widely disseminated disease where no treatment options were available. A rare case of cervical carcinoma presenting as metastasis in breast is reported here where palliative mastectomy improved the general condition of the patient. A female patient aged 58 years was diagnosed and treated for cervical carcinoma, FIGO stage 2B. Four months after the treatment which included both external beam and intracavitory radiotherapy, the patient presented with breast and lung metastasis. Palliative mastectomy was done which improved the general condition of the patient. Metastatic carcinoma of the cervix can present as a case of breast carcinoma. In an appropriate setting, this possibility should be kept in mind. Palliative mastectomy should be offered for patients of cervical carcinoma with metastasis to breast when needed.

Full Text Available Abstract This study aimed to describe an unusual case of metachronous isolated inguinal lymph nodes metastasis from sigmoid carcinoma. A 62-year-old man was referred to our department because of an obstructing sigmoid carcinoma. Colonoscopy showed the obstructing lesion at 30 cm from the anal verge and abdominal CT revealed a sigmoid lesion infiltrating the left lateral abdominal wall. The patient underwent a colonic resection extended to the abdominal wall. Histology showed an adenocarcinoma of the colon infiltrating the abdominal wall with iuxtacolic nodal involvement. Thirty three months after surgery abdominal CT and PET scan revealed a metastatic left inguinal lymph node involvement. The metastatic lymph node was found strictly adherent to the left iliac-femoral artery and encompassing the origin of the left inferior epigastric artery. Histology showed a metachronous nodal metastasis from colonic adenocarcinoma. Despite metastastic involvement of inguinal lymph node from rectal cancer is a rare but well known clinical entity, to the best of our knowledge, this is the first report of inguinal metastasis from a carcinoma of the left colon. Literature review shows only three other similar reported cases: two cases of inguinal metastasis secondary to adenocarcinoma of the cecum and one case of axillary metastasis from left colonic carcinoma. A metastatic pathway through superficial abdominal wall lymphatic vessels could be possible through the route along the left inferior epigastric artery. The solitary inguinal nodal involvement from rectal carcinoma could have a more favorable prognosis. In the case of nodal metastasis to the body surface lymph nodes from colonic carcinoma, following the small number of such cases reported in the literature, no definitive conclusions can be drawn.

Objective: To investigate the related factors of mucosal melanoma of head and neck with lymph node metastasis for early diagnosis and further treatments. Method: A retrospective analysis of 117 cases of head and neck mucosal malignant melanoma patients which received surgical treatment was performed. Eleven cases of patients with pathologically confirmed lymph node metastasis and 33 cases without lymph node metastasis (1∶3) were randomly selected to analyze. The related factors of lymph node metastasis of head and neck mucosal melanoma patients including age, gender, whether the existence of recurrence, bone invasion, lesion location were analyzed. The single factor and logistic regression analysis were performed, P difference was statistically significant. Result: The lymph node metastasis rate of head and neck mucosal melanoma was 9.40%(11/117), the single factor analysis showed that there were 3 factors to be associated with lymph node metastasis, which was recurrence ( P =0.0000), bone invasion ( P =0.001), primary position ( P =0.007). Recurrence ( P =0.021) was a risk factor for lymph node metastasis according to the Logistic regression analysis, and the impact of bone invasion ( P =0.487) and primary location ( P =0.367) remained to be further explored. Conclusion: The patients of head and neck mucosal melanoma with the presence of recurrent usually accompanied by a further progression of the disease, such as lymph node metastasis, so for recurrent patients should pay special attention to the situation of lymph node and choose the reasonable treatment.

Anal metastases from lung cancer are infrequent, and there are only 10 published cases. Life expectancy is no longer than 1 year after diagnosis because of the typically advanced stage of disease. Treatment, which is typically inefficient, is administered with the intent to cure or avoid local complications. We report a case of a patient with non-small cell lung cancer presenting with perianal metastasis mimicking an abscess. Because perianal masses may be misdiagnosed, patients with lung and other cancers should be evaluated for metastatic disease.

Full Text Available We report the case of a 67-year-old man affected by metastatic esophageal cancer. The patient developed a symptomatic heart metastasis presenting as mimicking ST-segment elevation myocardial infarction. Cardiac magnetic resonance imaging (MRI documented the presence of a mass in the apex and septum of the left ventriculum. The dissemination of cancer was confirmed by the detection of circulating tumor cells (CTCs in the peripheral blood, measured by the CellSearch System (Veridex, LLC, Raritan, N.J., USA. The blood sample drawn at cardiac disease progression revealed the presence of 2 CTCs per 7.5 ml of blood. This report highlights the potential role of CTCs as markers of metastatic spread.

Full Text Available Tuberculosis (TB presenting as isolated liver mass without clinical evidence of TB is difficult to diagnose preoperatively and is usually mimicked by primary or metastatic carcinoma of the liver. Hepatic TB associated with carcinoma colon is a rare association which has very rarely been reported in the literature. This case illustrates the diagnostic difficulties of hepatic TB and the need to consider it in the differential diagnosis of hepatic nodular lesions in carcinoma colon patients. Here, we report a case of 48-year-old female who presented in the casualty with features of acute intestinal obstruction. Preoperatively a mass was seen at the hepatic flexure along with three lesions in the liver presumed to be metastatic in origin. However, histopathology of the mass revealed adenocarcinoma colon and the liver lesion proved to be hepatic TB. We wish to highlight that on encountering a hepatic lesion in a carcinoma colon patient the possibility of hepatic TB should also be kept in mind apart from the obvious possibility of metastasis especially in an endemic country like India.

Full Text Available Uveal melanoma is a rare malignancy. Its clinical course is highly agressive. At thetime of diagnosis, extraocular extension is present in most of the cases.We present a case of 69-year-old white man admitted for sharp orbital pain. Advanced uveal melanoma was diagnosed. We found black-colored tumor rotruding from the left eye and multiple cutaneous metastases on the scalp. CT scan revealed intracranial tumor mimicking meningeoma in the left parietal region. Lymhogenous metastases were not found and other hematogenous metastases were excluded. After biopsy of the eye tumor and excisional biopsy of one skin tumor, the uveal melanoma was diagnosed and the left orbital exenteration and extirpation of intracranial tumor were performed. The reconstruction was performed using galeacutaneous flap harvested from craniotomy flap. Postoperative course was uneventful and the patient was released from pain. He refused the additional oncological treatment. After four months, he died of liver metastatic disease.The uveal melanoma is highly aggressive malignancy and isolated subdural metastasis is quite rare. The reconstruction with transposed galeacutaneous flap is versatile and secure technique after orbital exenteration.

Full Text Available BACKGROUND Brain neoplasms occur at all ages and account for around 2-3 percent of all deaths in adults. In children, the frequency increases to more than twenty percent. In children, it forms the second most common type of malignancy. Most of the tumours encountered are not related to any identifiable risk factors except for irradiation and some hereditary syndromes like subependymal giant cell astrocytoma, glioblastoma multiforme, cerebellar haemangioblastoma, meningioma, Schwannoma of 7 th cranial nerve. Gliomas constitute fifty percent of the brain tumours and sixty percent of all gliomas are glioblastoma multiforme. Meningiomas constitute twenty percent and cerebral metastasis is seen in fifteen percent of the cases. Seventy percent of supratentorial tumours are found in adults and seventy percent of brain tumours in children are infratentorial. The three common tumours of cerebellum are medulloblastoma, haemangioblastoma and juvenile pilocytic astrocytoma. Brain tumours are space occupying lesions and cause compression and destruction of adjacent structures, brain oedema (Peritumoural tissue, infarction and ischaemia of brain by compressing/infiltrating cerebral blood vessels, obstruction of CSF flow causing hydrocephalus, and rise in intracranial pressure with herniations. Tumours can undergo ischaemic necrosis and necrotic tumours tend to bleed. Brain tumours generally do not metastasise. Schwannoma and meningioma are benign tumours. Medulloblastoma of childhood may have drop metastasis via CSF. A sincere effort has been put in this study to identify the incidence of each variety of brain tumour among the fifty confirmed and identified cases of brain tumours. METHODS The age range of the cases in present study was 5-72 years with a mean age of occurrence of 44.11 years and the peak age group affected were in the 3 rd and 4 th decades. Cerebral hemisphere was the commonest site for intracranial tumours. RESULT In the present study, fifty

To evaluate the pattern of distant lymph node metastasis in colorectal carcinoma and its correlation with distant organ metastasis. We retrospectively reviewed abdominal CT scans of 46 patients with pathologically proven colorectal carcinoma. The incidence of distant lymphadenopathy in colorectal carcinoma was 30.4%(14/46). The most commonly involved distant lymph node was the left paraortic lymph node below the renal hilum(9/25). The most common type of distant lymphadenopathy was solitary type(7/14) and all of these lymphadenopathies were noted in the left paraortic lymph node below the renal hilum. Six cases of left sided colorectal carcinoma showed left paraortic lymphadenopathy with solitary type. The incidence of distant organ metastasis was 17.4%(8/46) and markedly increased if distant lymphadenopathy was multiple and confluent, or confluent type(5/7). The incidence of distant lymphadenopathy in colorectal carcinoma was not high and the most common lymphadenopathy was the left paraortic lymph node with solitary type below the renal hilum. The possibility of distant organ metastasis was high if distant lymphadenopathy was multiple and confluent, or confluent type

Lung cancer is the most common cancer in the world. Despite this, there have been few cases of simultaneous primary and metastatic cancers in the lung reported, let alone coexisting with tumor-to-tumor metastasis. Herein, we describe an extremely unusual case. A 61-year-old man with a history of colon adenocarcinoma was revealed as having three nodules in the lung 11 months after colectomy. The nodule in the left upper lobe was primary lung adenocarcinoma, the larger one in the right upper lobe was a metastasis of colon adenocarcinoma, and the smaller one in the right upper lobe was colon adenocarcinoma metastasizing to lung adenocarcinoma. Our paper focused on the differential diagnosis and cancer staging of this unique case, and discussed the uncommon phenomenon of the lung acting as a recipient in tumor-to-tumor metastasis.

International and national recommendations for brain imaging in patients planned to undergo potentially curative resection of non-small-cell lung cancer (NSCLC) are variably implemented throughout the United Kingdom [Hudson BJ, Crawford MB, and Curtin J et al (2015) Brain imaging in lung cancer patients without symptoms of brain metastases: a national survey of current practice in England Clin Radiol https://doi.org/10.1016/j.crad.2015.02.007]. However, the recommendations are not based on high-quality evidence and do not take into account cost implications and local resources. Our aim was to determine local practice based on historic outcomes in this patient cohort. This retrospective study took place in a regional thoracic surgical centre in the United Kingdom. Pathology records for all patients who had undergone lung resection with curative intent during the time period January 2012-December 2014 were analysed in October 2015. Electronic pathology and radiology reports were accessed for each patient and data collected about their histological findings, TNM stage, resection margins, and the presence of brain metastases on either pre-operative or post-operative imaging. From the dates given on imaging, we calculated the number of days post-resection that the brain metastases were detected. 585 patients were identified who had undergone resection of their lung cancer. Of these, 471 had accessible electronic radiology records to assess for the radiological evidence of brain metastases. When their electronic records were evaluated, 25/471 (5.3%) patients had radiological evidence of brain metastasis. Of these, five patients had been diagnosed with a brain metastasis at initial presentation and had undergone primary resection of the brain metastasis followed by resection of the lung primary. One patient had been diagnosed with both a primary lung and a primary bowel adenocarcinoma; on review of the case, it was felt that the brain metastasis was more likely to have

The purpose of this study was to develop a nude mouse model of bone metastasis by performing intracardiac injection of breast cancer cells under ultrasonography guidance and we wanted to evaluate the development and the distribution of metastasis in vivo using micro-CT, MRI and bioluminescence imaging. Animal experiments were performed in 6-week-old female nude mice. The animals underwent left ventricular injection of 2x105 MDA-MB-231Bo-Luc cells. After injection of the tumor cells, serial bioluminescence imaging was performed for 7 weeks. The findings of micro-CT, MRI and the histology were correlated with the 'hot' lesions seen on the bioluminescence imaging. Metastasis was found in 62.3% of the animals. Two weeks after intracardiac injection, metastasis to the brain, spine and femur was detected with bioluminescence imaging with an increasing intensity by week 7. Micro-CT scan confirmed multiple osteolytic lesions at the femur, spine and skull. MRI and the histology were able to show metastasis in the brain and extraskeletal metastasis around the femur. The intracardiac injection of cancer cells under ultrasonography guidance is a safe and highly reproducible method to produce bone metastasis in nude mice. This bone metastasis nude mouse model will be useful to study the mechanism of bone metastasis and to validate new therapeutics

Surgery offer the only curative treatment for colorectal hepatic metastasis. Nowadays, five-year survival increases up to 58% in selected cases, due to the improvement and combination of chemotherapy, surgery and ablative treatment like embolisation, radio-frequency or cryoablation. Surgery should be integrated in a multi disciplinary approach and initial work-up must take in account patient general conditions, tumor location, and possible extra hepatic extension. Thus, a surgical resection may be performed immediately or after preparation with chemotherapy or selective portal embolization. Management of liver metastasis should be carried out in oncological hepato-biliary centre.

Highlights: •PCDH7 is overexpression in high bone metastatic MDA-MB-231 cells. •PCDH7 is up-regulation in bone metastatic breast cancer tissues. •Suppression of PCDH7 inhibits cell proliferation, migration, and invasion in vitro. •PCDH7 induces breast cancer bone metastasis in vivo. -- Abstract: Breast cancer had a propensity to metastasize to bone, resulting in serious skeletal complications associated with poor outcome. Previous study showed that Protocadherin-7 (PCDH7) play an important role in brain metastatic breast cancer, however, the role of PCDH7 in bone metastatic breast cancer has never been explored. In the present study, we found that PCDH7 expression was up-regulation in bone metastatic breast cancer tissues by real-time PCR and immunohistochemistry assays. Furthermore, suppression of PCDH7 inhibits breast cancer cell proliferation, migration, and invasion in vitro by MTT, scratch, and transwell assays. Most importantly, overexpression of PCDH7 promotes breast cancer cell proliferation and invasion in vitro, and formation of bone metastasis in vivo. These data provide an important insight into the role of PCDH7 in bone metastasis of breast cancer.

We report a case of a 39-year-old man with intractable multifocal pain caused by metastatic urachal carcinoma to the bone. The patient underwent a partial cystectomy in May 2008, and lung metastasis occurred 9 months after the surgery. He then received salvage chemotherapy, but developed metastasis to the liver, brain, and bone. He was hospitalized due to a shoulder pain, a lower back pain, buttocks pain, numbness in both legs, and drop foot in right leg. MRI revealed metastases to the spine, and lumbar spinal canal stenosis with cauda equina compression. Even a combination of fentanyl-patch, oral acetaminophen, gabapentin and paroxetine was not effective for pain control. Strontium-89 therapy and subarachnoid phenol block successfully eliminated intractable pain. The patient could be discharged from hospital and received a palliative care at home for a short period of time. (author)

Whole-brain radiation therapy (WBRT) is widely applied in cases of brain metastases of non-small cell lung cancer (NSCLC). However, there are few case reports on hemorrhages of brain metastases occurring after WBRT. A 63-year-old woman was given a diagnosis of stage IV (T4N0M1b) lung adenocarcinoma about 4 years previously, and received chemotherapy regimens and gamma knife radiosurgery. However, her brain metastases exacerbated and she received WBRT in November 2010 and docetaxel monotherapy in December 2010. Two weeks after completing WBRT, she experienced dysarthria and an MRI showed multiple hemorrhages within brain metastases. Over a period of careful observation, these hemorrhages repeatedly alternated between improvement and exacerbation. Radiotherapy for metastatic brain tumors is considered to suppress hemorrhagic events of brain metastases. However, multiple intracranial hemorrhages of brain metastases occurred after WBRT in the present case. The accumulation of further studies of similar cases is necessary to identify the exact mechanism of these hemorrhages. (author)

Changes in the relative risk and sites of central nervous system metastasis with effective combined chemotherapy and radiation therapy for small cell carcinoma of the lung

Prolongation of survival of patients with small cell carcinoma of the lung with current effective systemic therapy has been accompanied by a marked increase in the frequency of relapse in the central nervous system (CNS). Prophylactic cranial irradiation (PCI) was shown to reduce the frequency of brain metastasis, but there was no increased short-term survival. Therefore, the necessity for PCI early in the course of treatment has been questioned, especially for patients with extensive disease. From January 1974 through March 1982, 205 patients with small cell carcinoma of the lung were treated at the Medical College of Wisconsin Affiliated Hospitals. None had clinical, radioisotopic, or computed tomographic evidence of brain metastasis. Eighty-two patients received radiotherapy and chemotherapy, but no PCI; 123 patients received combination chemotherapy and radiation therapy with PCI. The cumulative probability of brain metastasis without PCI was 36% at 12 months and 47% at 24 months; the probabilities were 6 and 10%, respectively with PCI. The 24-month probability of brain metastasis in patients with limited disease and no PCI was 45%; for those with extensive disease, it was 47%. No patient presented with extracranial central nervous system (ECNS) metastasis and no one without PCI developed it. Twelve patients who received PCI developed ECNS metastasis; the cumulative probabilities rose to 14% at 12 months and 22% at 24 months. The increased frequency of ECNS involvement has led to a phase I trial of PCI followed by six cycles of combination chemotherapy, without maintenance chemotherapy, followed by irradiation of the chest and spinal cord for patients with complete response

Purpose : Primary sphenoid carcinoma is rare. It accounts for 0.3% of all primary paranasal sinus malignancies. Because of the rarity of sphenoid carcinoma, large series of patients with outcome and survival statistics are currently unavailable. So we followed up the 1 case of sphenoid sinus carcinoma treated in our hospital and reported the course of the disease. In a review of case reports and small series of patients, 2-year survival was 7%. Our case is alive at 29 months after diagnosis of sphenoid sinus carcinoma. Intramedullary spinal cord metastasis (ISCM) is an unusual complication of cancer. In our case rapidly progressive paraparesis and urinary retention developed at 25 months after diagnosis of sphenoid sinus carcinoma. MRI of the thoracic spines showed the intramedullary spinal cord tumor mass at T3 and T4 level with accompanying syringomyelia. Here we report a case of ISCM associated with syringomyelia which has developed after primary sphenoid sinus carcinoma with a review of literature about the clinical behavior and treatment of this lesion

Soft tissue metastases, in particular intraneural metastasis, from any carcinomas seldom occur. To our knowledge, no case of sciatic nerve palsy due to intraneural metastasis of gastric carcinoma is reported in the literature. A case is reported of a 82-year old woman with sciatic nerve palsy with intraneural metastasis of gastric carcinoma. Although she had undergone partial gastrectomy with T2b, N0, M0 two years ago and primary site was cured, she developed sciatic nerve palsy from the carcinoma metastasis directly to the nerve. Operative resection and Histological examination revealed poorly differentiated adenocarcinoma, the same as her primary site adenocarcinoma. Sciatica is usually caused by a herniated disc or spinal canal stenosis. Sciatic nerve palsy may be caused by nondiscogenic etiologies that may be either intrapelvic or extrapelvic. It is important to image the entire course of the nerve to distinguish these etiologies quickly. The longer the nerve compression the less likely a palsy will recover. Surgery is a good intervention that simultaneously obtains a tissue diagnosis and decompresses the nerve

Full Text Available Dedifferentiated liposarcoma (DDL is a histologically pleomorphic sarcoma, traditionally defined as well-differentiated liposarcoma with abrupt transition to high grade, nonlipogenic sarcoma. It can occur as part of recurrent well-differentiated liposarcoma, or may arise de novo. DDL most frequently occurs within the retroperitoneum, and while it is prone to local recurrence, it usually has a lower rate of metastasis than other pleomorphic sarcomas. We describe a case of retroperitoneal dedifferentiated liposarcoma in a 63-year-old male, who showed MDM2 amplification with fluorescence in situ hybridization, which displayed unusually aggressive behavior, with brain, lung and subcutaneous soft tissue metastases. As previous reports of metastatic liposarcoma have largely grouped DDL in with other (genetically and clinically distinct liposarcoma subtypes, we highlight and discuss the rare occurrence of brain metastasis in MDM2-amplified retroperitoneal liposarcoma.

Urethral metastasis from colorectal cancer is rare and is known to have a poor prognosis. A 72 year old man with a history of colectomy and colostomy due to sigmoid colon cancer was admitted to the emergency room with bowel distension, rectal bleeding and urinary symptoms. Computed tomography of the abdominopelvis showed sigmoid colon cancer with multiple metastases involving the liver. Positron emission tomography with F 18 fluorodeoxyglucose (FDG) showed multiple hypermetabolic foci in the liver, penis and pubic bone, which otherwise could not be diagnosed. The lesions revealed no improvement with chemotherapy and urological surgery on follow up F 18 FDG PET/CT. We present a case of urethral metastasis of sigmoid colon cancer diagnostically and prognostically indicated by F 18 FDG PET/CT.

Mechanism of case processing in the brain: an fMRI study.

Full Text Available In sentence comprehension research, the case system, which is one of the subsystems of the language processing system, has been assumed to play a crucial role in signifying relationships in sentences between noun phrases (NPs and other elements, such as verbs, prepositions, nouns, and tense. However, so far, less attention has been paid to the question of how cases are processed in our brain. To this end, the current study used fMRI and scanned the brain activity of 15 native English speakers during an English-case processing task. The results showed that, while the processing of all cases activates the left inferior frontal gyrus and posterior part of the middle temporal gyrus, genitive case processing activates these two regions more than nominative and accusative case processing. Since the effect of the difference in behavioral performance among these three cases is excluded from brain activation data, the observed different brain activations would be due to the different processing patterns among the cases, indicating that cases are processed differently in our brains. The different brain activations between genitive case processing and nominative/accusative case processing may be due to the difference in structural complexity between them.

BRAIN METASTASES OF GERM CELL TUMORS. THE RUSSIAN CANCER RESEARCH CENTER'S EXPERIENCE

Full Text Available This paper analyzes the experience in treating 20 patients with nonseminomatous germ cell tumors metastasizing to the brain. It presents brain metastasis-associated factors: multiple lung metastases; IGCCCG poor prognosis; and a baseline human chorionic gonadotropin level of > 50000 mIU/ml. The authors have identified a group to be screened for brain metastasis, which includes patients with intermediate/poor prognosis and multiple lung metastases. Long-term survival was achieved in 45 % of patients with baseline brain damage and in 22 % of those with metastases revealed after first-line chemotherapy. The positive prognostic factors associated with long-term survival were a single brain lesion, no neurological symptoms, and achievement of clinical complete personse in the brain.

A 53-year-old woman complaining of a cervical mass and intractable lumbago was admitted to the hospital. Eight years ago she had a tumor in her left thyroid lobe enucleated and it proved to be a microfollicular adenoma. This time she underwent total thyroidectomy under the diagnosis of thyroid cancer with vertebral metastasis and this was followed by /sup 131/I therapy but severe lumbago remained unchanged. Irradiation to the lumbar vertebra was added and this greatly relieved her from pain. Pathological examination revealed poorly differentiated thyroid carcinoma. We suppose that the unusually excellent radiosensitivity of this bone metastasis was attributable to its histopathological nature.
