    Full Text Available A case of widespread hematogenous metastases and Trousseau's syndrome is reported in a 40 year-old white housewife with gastric cancer, presenting subdural hematoma, ecchymoses, epistaxis, stomach and uterine bleeding. After undergoing hematoma drainage, she was unsuccessfully treated with platelets, red blood cells, plasma cryoprecipitate transfusions, and antibiotics. Necropsy disclosed gastric ring-signet adenocarcinoma invading the serous layer, with massive disseminated intravascular coagulation and systemic neoplastic embolism. Multiple old and recent hyaline (rich in fibrin and platelets microthrombi, and tumor emboli were observed in the bone marrow, meninges, liver, lungs, kidneys, lymph nodes, adrenals, thyroid, heart, pancreas, and ovaries (Krukenberg tumor.

    This paper describes the imaging features of ovarian metastases from adenocarcinoma of the colon in adolescent females. We reviewed retrospectively abdominal and pelvic computed tomographic and pelvic ultrasound examinations, histologic slices, and clinical charts of six adolescent females with ovarian metastases secondary to adenocarcinoma of the colon. One patient had ovarian metastasis at presentation and was presumed to have a primary ovarian tumor. The ovarian metastases were either solid (n = 3), complex with both solid and cystic components (n = 2), or multilocular cysts (n = 1). The ovarian lesions were large, ranging from 6 cm to 18 cm in diameter. Colorectal carcinoma in adolescent females is frequently associated with ovarian metastases. One imaging characteristic differs in adult and adolescent ovarian metastases, although they do have features in common: in adolescents, a smaller proportion of colorectal ovarian metastases are multicystic (17%) compared with the adult series (45%). These lesions are frequently large and may be complex, multicystic, or solid. Although it is a rare disease, the differential dignosis of adnexal masses in adolescent females should include ovarian metastases from adenocarcinoma of the colon. (orig.)

    Given the encouraging results from our previous work on the clinical application of BNCT on non-resectable, chemotherapy resistant liver metastases, we explore the possibility to extend our technique to lung metastases. A fundamental requirement for BNCT is achieving higher {sup 10}B concentrations in the metastases compared to those in healthy tissue. For this reason we developed a rat model with lung metastases in order to study the temporal distribution of {sup 10}B concentration in tissues and tumoral cells. Rats with induced lung metastases from colon adenocarcinoma were sacrificed two hours after intraperitoneal Boronphenylalanine infusion. The lungs were harvested, frozen in liquid nitrogen and subsequently histological sections underwent neutron autoradiography in the nuclear reactor Triga Mark II, University of Pavia. Our findings demonstrate higher Boron uptake in tumoral nodules compared to healthy lung parenchyma 2 hours after Boronphenylalanine infusion.

    Full Text Available We present the case of a 32-year-old woman who, 10 months after abdominoperineal resection and total mesorectal excision for a locally advanced mucinous adenocarcinoma of the rectum, presented with local recurrence and metastases to the breast, spine, the left eye and orbit. Following surgery, due to the patient's personal reasons, adjuvant chemoradiation was not given. The patient died 2 months later, with disseminated cancer. To the best of our knowledge, breast as well as ocular metastasis in a patient with mucinous adenocarcinoma of the rectum has never been reported and, therefore, needs to be documented.

    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.

    Full Text Available Abstract Background Appendiceal adenocarcinoma is rare with a frequency of 0.08% of all surgically removed appendices. Few cases of appendiceal carcinoma infiltrating the bladder wall for spatial contiguity have been documented. Case Presentation A case is reported of a 45-years old woman with mucinous cystadenocarcinoma of the appendix with bladder metastasis. Although ultrasonography and voided urinary cytology were negative, abdomen computed tomography (CT scan and cystoscopy and subsequent pathological examination revealed a mass exclusively located in the anterior wall of the bladder. Histopathology of the transurethral bladder resection revealed a bladder adenocarcinoma [6 cm (at the maximum diameter × 2,5 cm; approximate weight: 10 gr] with focal mucinous aspects penetrating the muscle and perivisceral fat. Laparotomy evidenced the presence of a solid mass of the appendix (2,5 cm × 3 cm × 2 cm extending to the loco-regional lymph nodes. Appendectomy and right hemicolectomy, linfoadenectomy and partial cystectomy were performed. The subsequent pathological examination revealed a mucinous cystadenocarcinoma of the appendix with metastatic cells colonising the anterior bladder wall and several colic lymph nodes. Conclusions The rarity of the appendiceal carcinoma invading the urinary bladder and its usual involvement of nearest organs and the posterior bladder wall, led us to describe this case which demonstrates the ability of the appendiceal cancer to metastasize different regions of urinary bladder.

    We herein report a case of lung metastases with unusual radiological appearances that mimicked those of chronic airway infection, causing diagnostic difficulty. A 60-year-old woman who underwent liver transplantation from a living donor was incidentally diagnosed with bile duct adenocarcinoma after a histopathological analysis of her explanted liver. Six months later, chest computed tomography (CT) revealed bilateral bronchogenic dissemination that had gradually worsened, suggesting chronic airway infection. A biopsy with bronchoscopy from a mass lesion beyond a segmental bronchus revealed adenocarcinoma identical to that of her bile duct adenocarcinoma, leading to the diagnosis of multiple lung metastases from bile duct adenocarcinoma.

    Bone scintigraphy was used to diagnose osseous metastasis of prostatic adenocarcinoma in a 10-year-old dog with neck pain and ataxia and a large, sensitive prostate gland. Although radiography revealed a normal spine, prostatic fluid cytologic and ultrasonographic findings were compatible with prostatitis or neoplasia. Scintigraphic hot spots were seen in the axial skeleton, ribs, pelvis, humerus, and femur and corresponded to sites of metastatic prostatic adenocarcinoma

    Full Text Available Liver transplantation is an option that improves quality of life and prolongs life expectancy in patients with different types of liver disease. Liver transplantation is controversial for colorectal metastases and is not recommended in clinical practice guidelines. In this case report, we present, to our knowledge, the first liver transplantation for colorectal metastases conducted in Colombia, with a successful follow-up of more than 2 years. Patients with these characteristics who underwent liver transplantation experience reduced mortality and exponentially improved quality of life.

    To identify the prognostic significance of the location of lymph node metastases in patients with esophageal or gastroesophageal junction (GEJ) adenocarcinoma treated with neoadjuvant therapy followed by esophagectomy. Detection of lymph node metastases in the upper mediastinum and around the celiac trunk after neoadjuvant therapy and resection does not alter the TNM classification of esophageal carcinoma. The impact of these distant lymph node metastases on survival remains unclear. Between March 2003 and September 2013, 479 consecutive patients with adenocarcinoma of the distal esophagus or GEJ who underwent transthoracic esophagectomy with en bloc 2-field lymphadenectomy after neoadjuvant therapy were included, and survival was analyzed according to the location of positive lymph nodes in the resection specimen. Two hundred fifty-three patients had nodal metastases in the resection specimen. Of these patients, 92 patients had metastases in locoregional nodes, 114 patients in truncal nodes, 21 patients in the proximal field of the chest, and 26 patients had both positive truncal and proximal field nodes. Median disease-free survival was 170 months in the absence of nodal metastases, 35 months for metastases limited to locoregional nodes, 16 months for positive truncal nodes, 15 months for positive nodes in the proximal field, and 8 months for nodal metastases in both truncal and the proximal field. On multivariate analysis, location of lymph node metastases was independently associated with survival. Location of lymph node metastases is an independent predictor for survival. Relatively distant lymph node metastases along the celiac axis and/or the proximal field have a negative impact on survival. Location of lymph node metastases should therefore be considered in future staging systems of esophageal and GEJ adenocarcinoma.

    Full Text Available Abstract Background Pleomorphic adenoma of the lacrimal gland is known to undergo malignant transformation when incompletely excised. Even if such a malignant change occurs, intracranial direct invasion and leptomeningeal seeding are seldom encountered. Case presentation A 50-year-old woman presented with malignant transformation associated with both intracranial invasion and multiple intracranial and spinal disseminations in the third recurrence of pleomorphic adenoma of the lacrimal gland, 6 years after initial treatment. MRI demonstrated increased extent of orbital mass, extending to the cavernous sinus. The patient underwent intensity-modulated radiation therapy (IMRT and Gamma Knife radiosurgery. Follow-up MRI showed multiple leptomeningeal disseminations to the intracranium and spine. Conclusion It is important to recognize that leptomeningeal intracranial and spinal disseminations of pleomorphic adenocarcinoma can occur, although it is extremely rare. To our knowledge, we report the first case of pleomorphic adenocarcinoma of the lacrimal gland presumably metastasizing to the intracranium and spine.

    To evaluate the antitumor activity and toxicity of icotinib as initial treatment in lung adenocarcinoma patients with brain metastases. Twenty-one patients with histologically or pathologically documented brain metastatic lung cancer were administered icotinib as initial treatment from 2011 to 2015 at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences. Chemotherapy response was assessed by Response Evaluation Criteria in Solid Tumors and toxicity was evaluated according to National Cancer Institute-Common Toxicity Criteria. Icotinib was administered three times per day at a dose of 125mg. The median overall and progression-free survival rates were 15.2 (1.2-31.5 months, 95% confidence interval [CI] 6.6-23.7 months) and 8.9 months (0.6-30.5 months, 95% CI 3.4-14.3 months), respectively. The overall response and disease control rates were 61.9% and 90.5%, respectively. Icotinib was well tolerated, and no grade 3/4 adverse events were observed. The most common grade 1/2 adverse events included acneiform eruptions (38.1%), diarrhea (19.0%), and stomatitis (9.5%). Icotinib is effective and well tolerated as initial treatment in lung adenocarcinoma patients with brain metastases.

    A case of metastatic adenocarcinoma of the thyroid is reported in which treatment by means of radioactive iodine has been successful. The patient was completely thyroidectomized for malignant adenoma in 1923, with neither thyrotoxicosis then nor hypothyroidism postoperatively; 15 years later there developed classic symptoms of hyperthyroidism and severe pain in the lower back. In October 1939 a pulsating tumor removed from the level of the 12th thoracic vertebra proved to be metastatic thyroid adenocarcinoma (histologically well differentiated, with small follicles and colloid). In the next two years hyperthyroidism increased and roentgenograms revealed new metastases in the lungs, upper part of the right femur, second rib on the left side, left ilium, and skull. Roentgenologic irradiation of the metastases proved ineffectual. In March 1943 a tracer dose of radioactive iodine revealed iodine retention by all the known lesions and no evidence of residual thyroid tissue in the neck. Therapeutic amounts of radioactive iodine were administered orally between May and October 1943. Definite and lasting clinical improvement followed. In April 1944 and March 1945 additional I* was administered with a resultant disappearance of pain, increase in weight, and progressive change in all clinical criteria in the direction of hypothyroidism. Roentgenographic evidence pointed to an arrest if not a regression of the disease. No untoward effects followed this therapy. Radioactive iodine seems to be an effective therapeutic agent in the control of this type of tumor.

    1985-01-01

    The effect of thorax irradiation on lung metastases, either occurring spontaneously from a primary mammary adenocarcinoma (M8013X) transplanted on the leg or artificially induced by intravenous injection of tumor cells was studied. Increasing the interval between the moment at which lung metastases are supposed to originate and the thorax irradiation resulted in a rapid decrease of the effectiveness of this treatment in preventing the development of lung metastases. Increasing the radiation dose led to an increased number of cures; however, an increased number of mice dying of lethal lung damage was also observed. Irradiation of the lungs of mice with 5 or 10 Gy, 24 hours, 7 days or 14 days prior to i.v. injection with tumor cells, did not significantly increase the number of mice with lung metastases. Immunological resistance against the tumor played a role in our experiments with both spontaneous and artificial lung metastases

    Full Text Available To establish a miRNA signature for metastasis in an animal model of esophageal adenocarcinoma (EAC.The incidence of esophageal adenocarcinoma (EAC has dramatically increased and esophageal cancer is now the sixth leading cause of cancer deaths worldwide. Mortality rates remain high among patients with advanced stage disease and esophagectomy is associated with high complication rates. Hence, early identification of potentially metastatic disease would better guide treatment strategies.The modified Levrat's surgery was performed to induce EAC in Sprague-Dawley rats. Primary EAC and distant metastatic sites were confirmed via histology and immunofluorescence. miRNA profiling was performed on primary tumors with or without metastasis. A unique subset of miRNAs expressed in primary tumors and metastases was identified with Ingenuity Pathway Analysis (IPA along with upstream and downstream targets. miRNA-linked gene expression analysis was performed on a secondary cohort of metastasis positive (n=5 and metastasis negative (n=28 primary tumors.The epithelial origin of distant metastasis was established by IF using villin (VIL1 and mucin 5AC (MUC5AC antibodies. miRNome analysis identified four down-regulated miRNAs in metastasis positive primary tumors compared to metastasis negative tumors: miR-92a-3p (p=0.0001, miR-141-3p (p=0.0022, miR-451-1a (p=0.0181 and miR133a-3p (p=0.0304. Six target genes identified in the top scoring networks by IPA were validated as significantly, differentially expressed in metastasis positive primary tumors: Ago2, Akt1, Kras, Bcl2L11, CDKN1B and Zeb2.In vivo metastasis was confirmed in the modified Levrat's model. Analysis of the primary tumor identified a distinctive miRNA signature for primary tumors that metastasized.

    Purpose/Objectives: Radiation therapy (RT) is the principal modality in the treatment of patients with brain metastases (BM). However, given the activity of EGFR tyrosine kinase inhibitors in the central nervous system, it is uncertain whether upfront brain RT is necessary for patients with EGFR-mutant lung adenocarcinoma with BM. Methods and Materials: Patients with EGFR-mutant lung adenocarcinoma and newly diagnosed BM were identified. Results: 222 patients were identified. Exclusion criteria included prior erlotinib use, presence of a de novo erlotinib resistance mutation, or incomplete data. Of the remaining 110 patients, 63 were treated with erlotinib, 32 with whole brain RT (WBRT), and 15 with stereotactic radiosurgery (SRS). The median overall survival (OS) for the whole cohort was 33 months. There was no significant difference in OS between the WBRT and erlotinib groups (median, 35 vs 26 months; P=.62), whereas patients treated with SRS had a longer OS than did those in the erlotinib group (median, 64 months; P=.004). The median time to intracranial progression was 17 months. There was a longer time to intracranial progression in patients who received WBRT than in those who received erlotinib upfront (median, 24 vs 16 months, P=.04). Patients in the erlotinib or SRS group were more likely to experience intracranial failure as a component of first failure, whereas WBRT patients were more likely to experience failure outside the brain (P=.004). Conclusions: The survival of patients with EGFR-mutant adenocarcinoma with BM is notably long, whether they receive upfront erlotinib or brain RT. We observed longer intracranial control with WBRT, even though the WBRT patients had a higher burden of intracranial disease. Despite the equivalent survival between the WBRT and erlotinib group, this study underscores the role of WBRT in producing durable intracranial control in comparison with a targeted biologic agent with known central nervous system activity.

Due to restrictive transport at the blood–brain barrier, many drugs provide poor control of metastases in the brain. The aim of this study was to compare erlotinib with pemetrexed as second-/third-line treatment in patients with lung adenocarcinoma with asymptomatic brain metastases.Methods: From January 2012 to June 2014, all lung adenocarcinoma patients with asymptomatic brain metastases who received treatment with erlotinib or pemetrexed as second-/third-line treatment were retrospectively reviewed. Chi-square and log-rank tests were used to perform statistical analysis.Results: The study enrolled 99 patients, of which 44 were positive for EGFR mutation. Median progression-free survival (PFS in months was not significantly different between the erlotinib- and pemetrexed-treated groups (4.2 vs 3.4 months; 95% confidence interval [CI]: 2.01–6.40 vs 2.80–5.00, respectively; P=0.635. Median PFS was found to be significantly longer in EGFR mutation–positive patients in the erlotinib-treated group (8.0 months; 95% CI 5.85–10.15 compared to the pemetrexed group (3.9 months; 95% CI: 1.25–6.55; P=0.032.

    Full Text Available Hepatectomy has been the standard treatment for metachronic metastases of non-colorectal (NCR origin, mainly when the disease-free interval is more than two years. Laparoscopic hepatectomy has become the golden standard mainly for left side resections, due to lower morbidity, shorter hospital stay, early recovery and good cosmetic outcome. The authors report the case of a female patient with two metachronic metastases (ten years of disease-free survival, of non-colorectal origin (adenocarcinoma of small intestine, treated by laparoscopic left lateral segmentectomy (left hepatic lobectomy with success. The postoperative progress was satisfactory. To date, the patient has presented no tumoral recurrence (six months of follow-up period. Laparoscopic left lateral segmentectomy can be satisfactorily performed in selected cases of hepatic metastasis. This approach presents low morbidity and good cosmetic result. The lack of alternative treatments and the poor prognosis of untreated cases have justified surgical resection in order to increase overall survival. Nevertheless, this approach should be performed by hepatic surgery expertise teams trained on advanced laparoscopic procedures.A hepatectomia tem sido o tratamento padrão para metástase de origem não colorretal (NCR metacrônica, principalmente quando o intervalo livre de doença é maior do que dois anos. A hepatectomia por laparoscopia tem se tornado padrão principalmente para as ressecções à esquerda, haja vista a menor morbidade, menor tempo de internação, reabilitação precoce e melhor resultado estético. Os autores relatam um caso de paciente com duas metástases metacrônicas (10 anos de sobrevida livre de doença, de etiologia não colorretal (adenocarcinoma de intestino delgado, tratada com segmentectomia lateral esquerda (lobectomia hepática esquerda laparoscópica.

    2006-01-01

    Introduction: Selective internal radiation therapy (SIRT) is a relatively new commercially available microbrachytherapy technique for treatment of malignant hepatic lesions using 9 Y embedded in resin microspheres, which are infused directly into the hepatic arterial circulation. It is FDA approved for liver metastases secondary to colorectal carcinoma and is under investigation for treatment of other liver malignancies, such as hepatocellular carcinoma and neuroendocrine malignancies. Materials/Methods: A modest number of clinical trials, preclinical animal studies, and dosimetric studies have been reported. Here we review several of the more important results. Results: High doses of beta radiation can be selectively delivered to tumors, resulting in impressive local control and survival rates. Ex vivo analyses have shown that microspheres preferentially cluster around the periphery of tumor nodules with a high tumor:normal tissue ratio of up to 200:1. Toxicity is usually mild, featuring fatigue, anorexia, nausea, abdominal discomfort, and slight elevations of liver function tests. Conclusions: Selective internal radiation therapy represents an effective means of controlling liver metastases from colorectal adenocarcinoma. Clinical trials have demonstrated improved local control of disease and survival with relatively low toxicity. Investigations of SIRT for other hepatic malignancies and in combination with newer chemotherapy agents and targeted biologic therapies are under way or in planning. A well-integrated team involving interventional radiology, nuclear medicine, medical oncology, surgical oncology, medical physics, and radiation oncology is essential for a successful program. Careful selection of patients through the combined expertise of the team can maximize therapeutic efficacy and reduce the potential for adverse effects

    Twenty-five cases of bone metastases involving the cortex alone are reviewed. Seven patients had primary lung carcinoma, while 18 had primary tumors not previously reported to produce cortical bone metastases (tumors of the breast, kidney, pancreas, adenocarcinoma of unknown origin, multiple myeloma). Radiographically, these cortical lesions were well circumscribed, osteolytic, and produced soft-tissue swelling and occasional periosteal reaction. A recurrent pattern of metadiaphyseal involvement of the long bones of the lower extremity (particularly the femur) was noted, and is discussed. Findings reported in the literature, review, pathophysiology, and the role of skeletal radiographs, bone scans, and CT scans in evaluating cortical bone metastases are addressed

    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)

    Objective: To explore the difference of CT features of cavitary pulmonary metastases(CPM)from squamous cell carcinoma (SCCCPM)and CPM from adenocarcinoma(ACCPM). Methods: CT findings of 61 CPM nodules in 13 patients with SCCCPM and 60 CPM nodules in 22 patients with ACCPM were retrospectively analyzed. Results: SCCCPM presented as bubble (n=13), irregular (n=9), cystic (n=26) or small circular (n=13) cavities. ACCPM presented as bubble (n=21), irregular (n=21) or small circular (n=18) cavities. No cystic cavity was found in ACCPM. The thickness of cavity wall was even in 57 CPM including 39 SCCCPM and 18 ACCPM. Of the 64 CPM with uneven cavity wall thickness, 22 were SCCCPM and 42 were ACCPM. Between SCCCPM and ACCPM, no statistically significant difference was found in the site, size and cavity wall thickness of CPM, cystic cavity and even cavity wall thickness were found much more in SCCCPM than ACCPM, which has statistically significant difference. Conclusion: Both SCCCPM and ACCPM had their own CT characteristics which was likely to predict the histological type of primary malignancy of CPM. (authors)

    Full Text Available Recently, certain endometrial carcinomas have been found to be associated with mismatch repair (MMR protein defects/deficiency. A 39-year-old female presented with cough, decreased appetite and significant weight loss since 2 months. Earlier, she had undergone total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH-BSO for endometrioid adenocarcinoma. Imaging disclosed an 8 cm-sized adrenal mass that was surgically excised. Histopathology of the adrenal tumor, endocervical tumor, and endometrial biopsy revealed Federation of Gynecology and Obstetrics (FIGO Grade II to III endometrioid adenocarcinoma. By immunohistochemistry, tumor cells were positive for cytokeratin 7, epithelial membrane antigen, PAX8, MLH1 and PMS2 while negative for estrogen receptor (ER, progesterone receptor (PR, MSH2 and MSH6. She underwent adjuvant radiotherapy and chemotherapy. A 34-year-old lady presented with vaginal bleeding since 9 months. She underwent TAH-BSO, reported as FIGO Grade III endometrioid adenocarcinoma. By immunohistochemistry, tumor cells were negative for ER, PR, MLH1, and PMS2 while positive for MSH2 and MSH6. She underwent adjuvant radiotherapy and chemotherapy. However, she developed multiple nodal and pericardial metastases and succumbed to the disease within a year post-diagnosis. Certain high-grade endometrioid adenocarcinomas occurring in younger women are MMR protein deficient and display an aggressive clinical course. Adrenal metastasis in endometrial carcinomas is rare.

    Full Text Available We report a patient with supraclavicular lymph node metastasis from an undetectable adenocarcinoma of the transverse colon, who presented with cough and was diagnosed with typhoid fever, bronchitis as well as liver metastasis. There were an abdominal fullness, weight loss, constipation, pencil-like stool with mucous and blood, low-grade fever, bone ache, and tea-color urine. The first colonoscopy revealed lymphocytic ileitis and microscopic findings also showed lymphocytic ileitis. Abdominal USG and CT revealed liver metastasis of unknown origin. Based on the clinical sign and symptoms, we suspected that colorectal carcinoma was the primary site. Then, the second colonoscopy was performed and it revealed a small polyp, which was followed with a biopsy and the result supported a well-differentiated colon adenocarcinoma. Similar result was also revealed by the histopathological evaluation. This is an unusual case of liver and supraclavicular lymph node metastasis arising from a small polyp adenocacinoma of the transverse colon.

    Phyllodes tumors are rare breast neoplasms. Surgery is the treatment of choice. The role of postoperative radiotherapy and chemotherapy is still under dispute, as there are no equivocal prognostic factors. Treatment failure results in the occurrence of distant metastasis-mainly to the lungs, bones, liver, and brain. We have described the case of a woman with a malignant phyllodes tumor of the breast that was surgically treated. She did not receive adjuvant therapy because there is no consensus on the role of postoperative chemotherapy and radiotherapy. One year following the surgery, the patient had left-sided nephrectomy performed because of a rapidly growing tumor of the kidney. Renal cancer was suspected; however, a histopathological examination revealed that it was a metastatic phyllodes tumor. At the same time, the patient was diagnosed as having metastases in the other kidney, the lungs, liver, and bones.Our case report describes not only an unusual localization of the metastases (in the kidneys), but also failure of the chemotherapy and the aggressive course of malignant phyllodes tumor. Identification of patients with high risk for distant metastasis and the introduction of uniform rules for the management of adjuvant chemotherapy and radiotherapy would make planning treatment as efficacious as possible.

    Full Text Available Introduction. Langerhans cell histiocytosis (LCH is an uncommon disease of unknown etiology characterized by uncontrolled proliferation and infiltration of various organs by Langerhans cells. Case report. We presented a 54-year-old man, heavy smoker, with dyspnea, cough, hemoptysis, headache and ataxia, who died shortly after admission to our hospital. On the autopsy, tumor was found in the posterior segment of the right upper pulmonary lobe as well as a right-sided occipitoparietal lesion which penetrated into the right ventricle resulting in internal and external hematocephalus. Histologically and immunohistohemically, the diagnosis of primary lung adenocarcinoma with brain metastasis was made (tumor cells showed positivity for CK7 and TTF-1 which confirmed the diagnosis. In the lung parenchyma around the tumor, as well as in brain tissue around the metastatic adenocarcinoma histiocytic lesions were found. Light microscopic examination of the other organs also showed histiocytic lesions involving the pituitary gland, hypothalamus, spleen and mediastinal lymph nodes. Immunohistochemical studies revealed CD68, S-100 and CD1a immunoreactivity within the histiocytes upon which the diagnosis of Langerhans' cells histiocytosis was made. Conclusion. The multisystem form of LCH with extensive organ involvement was an incidental finding, while metastatic lung adenocarcinoma to the brain that led to hematocephalus was the cause of death.

  1. Importance of immunohistochemistry and application of TTF-1 and napsin A in differential diagnosis of primary pulmonary adenocarcinomas and pulmonary metastases of extrapulmonary origins

    The differential diagnosis between primary and secondary pulmonary adenocarcinomas is daily requisition for pathologist. Lungs are the most common site of metastases from various primary and primary pulmonary adenocarcinomas are one of the most common worldwide malignancies. Immunohistochemistry is useful method to determine the origin of tumor in case when histomorphology alone is insufficient in poor differentiated carcinomas. Accordingly, presence of enteric, clear cell, spindle cell and signet-ring cell features complicates determining of origin of adenocarcinomas. The most common and long-used lung specific immunohistochemical marker is TTF-1, but specificity and sensitivity is not 100%. Use of TTF-1 has pitfalls that complicate its routine use. TTF-1 alone is insufficient marker for determining of origin of adenocarcinoma in the lung. Newly used immunohistochemical marker is napsin A. According to many authors is sensitivity and specificity for napsin A higher than TTF-1. Use of TTF-1 and napsin A simultaneously increases sensitivity up to 85% for primary lung adenocarcinomas. Both immunohistochemical l markers can be expressed in various tumours of extrapulmonary origin that can metastasize to lung, thus specificity is not 100%. In cases of surgical resection of tumor wider panels of immunohistochemical antibodies are used. Small biopsies and cytological material is quantitative restricted and sometimes qualitatively deficient. It is sometimes complicated and even impossible for pathologist to determine primary origin of tumor. (author)

    Adenocarcinoma cervix is an uncommon histological subtype of carcinoma cervix; further incidence of skeletal muscle metastases is even rarer. We report the identification of extensive fluorodeoxyglucose (FDG) avid metastatic skeletal muscle deposits in a known case of adenocarcinoma cervix. The largest lesion representative of muscle deposit in the right deltoid was histopathologically confirmed to be metastatic poorly differentiated carcinoma. This report also serves to highlight the importance of 18 F-FDG positron emission tomography/computed tomography (CT) as compared to conventional imaging modalities such as CT and ultrasonography and comments better over the description of invasiveness as well as the extent of disease in carcinoma cervix

    Full Text Available Cervical cancer is the most common cancer among females in India. Cervical cancer usually spreads by local extension and through the lymphatic drainage to the lymph nodes. Hematogenous spread, the mechanism responsible for distant metastases, is rarely seen in cervical malignancies. In this communication, we report a case of a 45-year-old woman who presented with unilateral decrease in vision of 3 months duration. She was found to have a serous retinal detachment with underlying diffuse, subretinal yellowish-cream colored infiltrates in the right eye, suspicious of choroidal metastases. Systemic evaluation showed disseminated systemic metastases arising from a primary adenocarcinoma of the cervix. In this communication, we review all the documented cases of metastases to the eye and adnexa arising from cervical cancer and their clinical characteristics. Unilateral choroidal metastasis arising from an adenocarcinoma of the cervix is extremely rare with only one previous documented case. Although uncommon, choroidal metastasis may be the presenting feature of primary cervical malignancy. Furthermore, cervical malignancy must be ruled out in women who present with orbital or choroidal metastases arising from unknown primary.

    Full text: Biphosphonates (BP) are very effective in treatment of bone metastatic disease. Their renal excretion defines one of the major side effects - nephrotoxicity. Glomerular filtration rate (GFR) is a basic parameter for its early detection but clinical practice often uses only serum creatinine. Aim of our retrospective study is to assess the role of dynamic kidney scintigraphy (DKS) and the estimated during it GFR in BP-treated patients with bone metastatic disease. 61 patients (53 female, 8 male), aged 33-82, with biphosphonate-treated bone metastases from breast (n53), lung (n1) and prostate (n7) cancer were enrolled for the period 27.04.2012-14.04.2015. Overall 77 studies were made, in 13 patients more than one. GFR was assessed in 57 studies. Results were compared with serum creatinine. All patients with elevated creatinine showed low GFR and decreased renal function at DKS. With normal creatinine and decreased GFR: in 31 studies kidney function was reduced, in 14 function was normal but kidney scintigraphic appearance was disturbed- mostly as in diffuse parenchymal disease. In 5 studies GFR was normal and renal function decreased. In 3 studies both parameters were normal. Zoledronic acid was changed with denosumab in 2 patients because of worsened function and strongly reduced GFR, in one patient BP was stopped after DKS. In 3 patients the interval between BP was extended because of affected renal function. GFR is more sensitive than serum creatinine levels and changes in nephrographic curves. Dynamic kidney scintigraphy is a functional method directing clinical reaction to preserve renal function

Both treatments imply significant side effects that a fine RT technique can help avoiding. Intensity Modulated RT (IMRT enables the treatment of the target volume while protecting normal tissue. It therefore reduces the incidence and severity of side effects. Case We report on a 50 year-old patient with a serous-papiliferous adenocarcinoma of the uterus who was submitted to surgical treatment without lymph node sampling followed by Brachytherapy, and Chemotherapy. The patient had a pelvic kidney, and was therefore treated with IMRT. So far, the patient has been free from relapse and with normal kidney function. Conclusion IMRT is a valid technique to prevent the kidney from radiation damage.

    Background: Bone metastasis is one of the most common clinical phenomena of late stage lung cancer. A major impediment to understanding the pathogenesis of bone metastasis has been the lack of an appropriate animal and cell model. This study aims to establish human lung adenocarcinoma cell line with highly bone metastases potency with 99m Tc-MDP bone scintigraphy. Methods: The human lung adenocarcinoma cancer cells SPC-A-1 were injected into the left cardiac ventricle of NIH-Beige-Nude-XID (NIH-BNX) immunodeficient mice. The metastatic lesions of tumor-bearing mice were imaged with 99m Tc-MDP bone scintigraphy on a Siemens multi-single photon emission computed tomography. Pinhole images were acquired on a GZ-B conventional gamma camera with a self-designed pinhole collimator. The mice with bone metastasis were sacrificed under deep anesthesia, and the lesions were resected. Bone metastatic cancer cells in the resected lesions were subjected for culture and then reinoculated into the NIH-BNX mice through left cardiac ventricle. The process was repeated for eight cycles to obtain a novel cell subline SPC-A-1BM. Real-time polymerase chain reaction (PCR) was used to compare the gene expression differences in the parental and SPC-A-1BM cells. Results: The bone metastasis sites were successfully revealed by bone scintigraphy. The established bone metastasis cell line SPC-A-1BM had a high potential to metastasize in bone, including mandible, humerus, thoracic vertebra, lumbar, femur, patella, ilium and cartilage rib. The expression level of vascular endothelial growth factor gene family, Bcl-2 and cell adhesion-related genes ECM1, ESM1, AF1Q, SERPINE2 and FN1 were examined. Gene expression difference was found between parental and bone-seeking metastasis cell SPC-A-1BM, which indicates SPC-A-1BM has metastatic capacity vs. its parental cells. Conclusion: SPC-A-1BM is a bone-seeking metastasis human lung adenocarcinoma cell line. Bone scintigraphy may be used as an

    Activin (a grape seed-derived proanthocyanidins extract) possess a broad spectrum of biological, pharmacological and therapeutic activities. The present study performed to investigate the preventive and modulating effects of dietary activin in radiation or murine mammary adenocarcinoma (MMA) induced damage in kidneys of albino mice throughout in vitro and in vivo studies. Activin was orally administered to mice for 5 consecutive days (100 mg/ kg body wt) before and 10 days post tumour inoculation. In irradiated group, animals were exposed to 6 Gy whole body gamma-radiations on the fifth day of tumour inoculation. Biochemical and histopathological studies were investigated. In vitro studies using MMA cells revealed that activin increase non viable tumour cell counts. In vivo studies, either MMA or gamma-irradiation resulted in biochemical, and histopathological changes leading to kidney damage. Biochemical studies revealed that activin treatment significantly restored the elevated activity of lactate dehydrogenase (LDH), ameliorated kidney functions profile, and depressed the levels of tumour markers, also enhanced glutathione content (GSH) and activities of superoxide dismutase (SOD) and catalase (CAT). It also reduced kidney lipid peroxides and improves serum total protein level. Histopathological changes in the kidney tissues were attenuated by activin treatment either in MMA-bearing mice group or irradiation group. Exposure of MMA-bearing mouse to gamma- radiations slightly improves the above mentioned damage. While dual treatment of MMA-bearing mice with activin and subsequence with gamma-radiation exposure was more effective. It could be concluded that activin through its antioxidant properties might attenuate radiation or MMA induced renal damage suggesting that activin may have a potential benefit in enhancing radiotherapy

    Gefitinib is regarded as a relatively safe agent for the treatment of an advanced non-small cell lung cancer (NSCLC). Pulmonary toxicity such as interstitial lung disease associated with gefitinib is uncommon with an estimated all time incidence around 1% worldwide. Moreover, a case of gefitinib associated with pulmonary cystic changes has not been reported yet. In this report we present a case of progressive multiple air cystic changes in both lungs in a patient with NSCLC and intrapulmonary metastases who underwent a gefitinib therapy.

    A 22-year-old female presented with multiple painless bilateral breast masses for the past 2 months. On Further questioning she had hematochezia and constipation for three months. On digital rectal examination, thickening of rectal mucosa at 5 cm from the anal verge was found. On physical examination, multiple firm, non-tender, nodular lesions were found in bilateral breasts. Metastatic breast disease from extra mammary primaries is uncommon and it constitutes 0.5 - 6% of all breast malignancies. melanomas, lymphomas, leukemias, ands sarcomas are the most common malignancies causing breast metastases. Infrequently, carcinomas of the lung, stomach, ovary, liver, tonsil, pleura, pancreas, cervix, perineum, endometrium, bladder, carcinoid tumors and renal cell carcinomas can cause metastatic breast disease. Metastatic breast disease from colorectal cancer is characterised by disseminated metastatic disease and a poor prognosis. In this case, It was essential to distinguish between metastatic breast disease primary breast carcinoma to plan appropriate management. Because of its rare incidence and high index of clinical suspicion, appropriate radiological investigations and histopathology is essential for accurate diagnosis. {sup 18}F-FDG PET/CT, being a whole-body metabolic functional imaging modality, helped us determine the extent of the primary and metastatic disease. In view of disseminated metastases, the bilateral breast disease was also considered as metastatic involvement, Which was proven by histopathology.

    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin.

    Discriminating intrahepatic cholangiocarcinoma (ICC) from hepatic metastases of pancreatic ductal adenocarcinoma (mPDAC) can be challenging. While pathologists might depend on clinical information regarding a primary tumor, their diagnosis will lead the patient either to potentially curative surgery (for ICC) or to palliation (for mPDAC). Beyond the validation of recently published potential biomarkers for PDAC (primary or metastatic) in a large cohort, we assessed diagnostic performance of the most promising candidates in the challenging task of discriminating metastatic PDAC (mPDAC) from ICC. In a training set of 87 ICC and 88 pPDAC, our previously identified biomarkers Annexin A1 (ANXA1), ANXA10, and ANXA13 were tested and compared with 11 published biomarkers or panels (MUCIN 1, Agrin, S100P, MUC5 AC, Laminin, VHL, CK 17, N-Cadherin, ELAC2, PODXL and HSPG2). Biomarkers with best results were further tested in an independent series of biopsies of 27 ICC and 36 mPDAC. Highest AUC values (between 0.72 and 0.84) for the discrimination between ICC and pPDAC were found in the training set for Annexin A1, Annexin A10, MUC5 AC, CK17, and N-Cadherin. These markers were further tested on an independent series of liver biopsies containing ICC or mPDAC. Diagnostic characteristics were evaluated for individual markers as well as for 3× panels. ANXA 10 showed the highest diagnostic potential of all single markers, correctly classifying 75% of mPDAC and 85% of ICC. Our results suggest that ANXA10 may be useful to differentiate between ICC and mPDAC, when only a tissue specimen is available.

    Purpose: Lung cancer remains the most common cause of both cancer mortality and brain metastases (BM). The purpose of this study was to assess the effect of gene alterations and tyrosine kinase inhibition (TKI) on median survival (MS) and cause of death (CoD) in patients with BM from lung adenocarcinoma (L-adeno). Methods: A multi-institutional retrospective database of patients with L-adeno and newly diagnosed BM between 2006 and 2014 was created. Demographics, gene alterations, treatment, MS, and CoD were analyzed. The treatment patterns and outcomes were compared with those in prior trials. Results: Of 1521 L-adeno patients, 816 (54%) had known alteration status. The gene alteration rates were 29%, 10%, and 26% for EGFR, ALK, and KRAS, respectively. The time from primary diagnosis to BM for EGFR−/+ was 10/15 months (P=.02) and for ALK−/+ was 10/20 months (P<.01), respectively. The MS for the group overall (n=1521) was 15 months. The MS from first treatment for BM for EGFR and ALK−, EGFR+, ALK+ were 14, 23 (P<.01), and 45 (P<.0001) months, respectively. The MS after BM for EGFR+ patients who did/did not receive TKI before BM was 17/30 months (P<.01), respectively, but the risk of death was not statistically different between TKI-naïve patients who did/did not receive TKI after the diagnosis of BM (EGFR/ALK hazard ratios: 1.06 [P=.84]/1.60 [P=.45], respectively). The CoD was nonneurologic in 82% of patients with known CoD. Conclusion: EGFR and ALK gene alterations are associated with delayed onset of BM and longer MS relative to patients without these alterations. The CoD was overwhelmingly nonneurologic in patients with known CoD.

    We have studied bone scintigrams in 60 patients with gastric cancer. Of these 60 patients, bone metastases were found in 15 patients (25 %). There were no evidence of bone metastases in polypoid lesions, cancers of the antrum, carcinomas in situ, advanced cancers without invasion to serosa, cancer with N 0 or N 1 regional lymph node metastases, highly deferenciated adenocarcinomas and papillary adenocarcinomas. On the contrary, high rates of bone metastases were seen in cancers of the corpus, advanced cancers with invasion to neighbouring structures and tubular adenocarcinomas. Of these 15 patients with bone metastasis, 3 patients showed very similar clinical features and the findings of ''diffuse bone metastases on bone scintigrams.'' Cancer of the antrum showed high rates of liver metastases, while cancers of the corpus showed high rates of bone stastases. Sixty percent of the patients with bone metastases did not have liver metastases and there seemed to be no significant relationship between liver metastases and bone metastases. From these results we suppose that non-portal tract through the vertebral venous plexus instead of portal tract may be the other route of bone metastases from gastric cancer. (author)

    Full Text Available Introduction: Follicular thyroid carcinoma (FTC is the second most common type of thyroid cancer, after papillary thyroid carcinoma (PTC, accounting for approximately 10% of all malignant thyroid tumours with higher predilection for women. FTC demonstrates capsular and/or vascular invasion and often presents with distant metastasis in 20%–30% of cases via the haematogenous spread. FTC tends to commonly metastasize to the lung and bone although other sites have been identified. Kidney metastasis from a primary FTC however is rare and has not been widely reported. We report a case of FTC with metastatic to the kidney in a patient presenting with a large left pelvic mass. Case presentation: A 54-year-old, Malay, lady with underlying hypertension and dyslipidaemia presented with chronic left pelvic pain since 1 year ago, following a fall during a recent vacation trip. She also experienced significant unintentional weight loss for the past few months. Clinical examination noted an ill-defined palpable firm mass over the left inner thigh. Pelvic radiograph showed a solitary ill-defined osteolytic lesion at the left superior and inferior pubic rami with cortical destruction. MRI of the pelvis showed a large lobulated enhancing expansile mass originating from the left pubic bone measuring 10.0(AP × 6.0(W × 8.5(CC cm, hypointense signal on T1W and hyperintense signal on T2W. The mass infiltrated adjacent bony structures and muscles. Patient subsequently undergone core biopsy of the left pelvic mass and histopathological examination (HPE noted metastatic follicular thyroid carcinoma. An ultrasound examination of the thyroid showed a multinodular goitre with suspicious nodule in the left thyroid gland. Pre-operative contrast-enhanced computed tomography (CECT showed primary thyroid carcinoma with nodal, lung and bone metastases with possible left kidney involvement. Total thyroidectomy was ensued and follicular thyroid carcinoma was confirmed based on

    Full Text Available In small animal imaging studies, when the locations of the micro-structures of interest are unknown a priori, there is a simultaneous need for full-body coverage and high resolution. In MRI, additional requirements to image contrast and acquisition time will often make it impossible to acquire such images directly. Recently, a resolution enhancing post-processing technique called super-resolution reconstruction (SRR has been demonstrated to improve visualization and localization of micro-structures in small animal MRI by combining multiple low-resolution acquisitions. However, when the field-of-view is large relative to the desired voxel size, solving the SRR problem becomes very expensive, in terms of both memory requirements and computation time. In this paper we introduce a novel local approach to SRR that aims to overcome the computational problems and allow researchers to efficiently explore both global and local characteristics in whole-body small animal MRI. The method integrates state-of-the-art image processing techniques from the areas of articulated atlas-based segmentation, planar reformation, and SRR. A proof-of-concept is provided with two case studies involving CT, BLI, and MRI data of bone and kidney tumors in a mouse model. We show that local SRR-MRI is a computationally efficient complementary imaging modality for the precise characterization of tumor metastases, and that the method provides a feasible high-resolution alternative to conventional MRI.

Primary neoplasms were located in the colon (20 patients), breast (six), stomach (five), small bowel (one), bladder (one), and Wilms tumor of the kidney (one). The radiographic appearance of the metastatic lesions could be described as predominantly cystic (14 lesions), mixed (12 lesions), or solid (seven lesions). The cystic and mixed lesions tended to be larger in overall diameter than the solid. The metastases from gastric carcinoma appeared solid in four of five cases. The metastases from the other neoplasms had variable appearances simulating primary ovarian carcinoma

    Tumor hemorrhage on computed tomography (CT) was found in 14 patients with brain metastases (7 % of two hundred patients with brain metastases), from April 1979 to July 1983. Primary foci of these lesions were the lung (6 patients), breast (2), kidney (2), uterus (2), colon (1) and adrenal gland (1). ''Stroke'' syndrome was the initial presenting symptom in 3 patients; neurological focal sign or symptoms of increased intracranial pressure in the remaining patients. CT demonstrated peritumoral hemorrhage in all patients with solid mass, intratumoral hemorrhage in a few patients and also cerebral or ventricular hemorrhage, which was fatal complication, in 2 patients (colon and breast cancers). A cystic mass with fluid-blood level was noted in a patient with breast cancer. Several predisposing factors including chemotherapy, thrombocytopenia, radiotherapy or combination of these were recognized in 8 patients. Of these, chemotherapy was the most causative factor of tumor hemorrhage. Brain irradiation for hemorrhagic brain metastases was effective for prolongation of mean survival time of these patients as follows; 10 months in irradiated group, whereas 1.5 months in non-irradiated group.

    Distant cutaneous metastases from cervical malignancies are uncommon, with scalp metastases being exceptional events. We present the case of a 53-year-old postmenopausal lady with adenocarcinoma of the uterine cervix that metastasized to the scalp with superior sagittal sinus thrombosis 8 months after diagnosis. In contrast to the seven prior cases of scalp metastases of cervical squamous cell carcinoma reported in published reports, ours is the first documentation of such an occurrence in cervical adenocarcinoma. Superior sagittal sinus thrombosis has not been reported with this tumour in the past.

    Full Text Available Metastasis of prostate carcinoma to the testis is seldom reported. The tumour may spread from the prostatic urethra by retrograde venous extension, arterial embolism or through direct invasion into the lymphatics and lumen of the vas deferens. Clinical manifestations of secondary testicular tumours from the prostate are most often unsuspected clinically and are instead detected incidentally during orchidectomy. Less frequently, a palpable mass is detected, which may be confused with a primary testicular neoplasm. We report a case of a 66-year-old patient with adenocarcinoma of the prostate, and a left testicular tumour that was diagnosed as metastases from prostate carcinoma after radical orchidectomy.

    Glandular neoplasms of the uterine cervix represent a small but important group of cervical carcinomas. Included in the present study were 68 cases of primary adenocarcinomas of the uterine cervix seen from 1972 to 1986 in our Radiation Oncology Center. The complete data set for all patients was analyzed with regard to symptoms, histologic patterns, diagnostic procedures, treatment methods, and prognosis. The authors stress the importance of establishing the primary origin of the lesion in the cervix and of completely investigating patients with an abnormal bleeding pattern, even those with an apparently normal exocervix

    Full Text Available Abstract Background Consolidation with or without ground-glass opacity is the typical radiologic finding of lung metastases of adenocarcinoma from the gastrointestinal tract. Lung excavated metastases from gastrointestinal carcinoma are very rare. Case presentation The authors describe an unusual presentation of multiple cavitated lung metastases from colon adenocarcinoma and discuss the outcome of a patient. The absence both of symptoms and other disease localizations, the investigations related to different diagnostic hypotheses and the empirical treatments caused a delay in correct diagnosis. Only a transparietal biopsy revealed the neoplastic origin of nodules. Conclusions This report demonstrates that although lung excavated metastases are described in literature, initial failure to reach a diagnosis is common. We would like to alert clinicians and radiologists to the possibility of unusual atypical features of pulmonary metastases from colon adenocarcinoma.

    Background: The effect of the palliative irradiation of bone metastases was explored in this retrospective analysis. The spectrum of primary tumor sites, the localization of the bone metastases and the fractionation schedules were analyzed with regard to palliation discriminating total, partial and complete pain response. Patients and Methods: One hundred seventy-six patients are included in this retrospective quantitative study from April 1992 to November 1993. Two hundred fifty-eight localizations of painful bone metastases were irradiated. The percentage of bone metastases of the total irradiated localizations in our department of radiotherapy in the Carite-Hospital, the primary tumor sites, the localizations and the different fractionation schedules were explored. The total, partial and complete pain response was analyzed in the most often used fractionation schedules and by primary tumor sites. Results: Eight per cent of all irradiated localizations in the observation period were bone metastases. There were irradiated bone metastases of 21 different tumor sites. Most of the primary tumor sites were breast cancer (49%), lung cancer (6%) and kidney cancer (6%). The most frequent site of metastases was the vertebral column (52%). The most often used fractionation schedules were: 4x5 Gy (32%), 10x3 Gy (18%), 6x5 Gy (9%), 7x3 Gy (7%), 10x2 Gy (5%) and 2x8 Gy. The total response rates in this fractionation schedules were 72%, 79%, 74%, 76%, 75% and 72%, the complete response rates were 35%, 32%, 30%, 35%, 33% and 33%. There were no significant differences between the most often irradiated primary tumor sites, the most frequent localizations and the palliation with regard to total, partial and complete pain response.

    A case of metastatic prostatic adenocarcinoma with concurrent Sertoli cell tumor is presented in an old, miniature Schnauzer dog. The prostatic neoplasm was highly anaplastic and had metastasized widely. Clinical signs were compatible with increased estrogen production. It is interesting to note that the prostatic carcinoma, usually considered to be androgen dependent, developed and metastasized, despite the presence of apparently increased estrogen levels.

    To evaluate CT findings of primary adenocarcinoma of the lung and to assess distant metastasis at the time of diagnosis. CT findings of 150 patients with adenocarcinoma, confirmed by histopathologic methods, were classified as central or peripheral lesion and pattern analysis of typical findings noted in this cancer was carried out. Intra and extrathoracic metastases of adenocarcinoma were also investigated. Of 150 cases of adenocarcinoma of the lung, 121 were found to be of the peripheral type and 29 were of the central type. These peripheral lesions comprised 105 nodules, 11 consolidations, four cavities and one linear lesion, while the central lesions consisted of 19 cases of atelectasis and tens of branchial wall thickening. lung to lung(nine cases), lymphangitic(five cases), and pleural metastasis(16 cases) were presented as intrathoracic metastasis, while bone(17), brain,(six), liver(two) and adrenal metastasis(one case)were presented as extrathoracic metastasis. The most common radiologic finding of adenocarcinoma is a peripheral single mass or nodule but consolidation, cavity or tubular lesions, as well as atelectasis or bronchial wall thickening alone can be presented as unusual findings of adenocarcinoma. As a consequence, it is in many cases difficult to differentially diagnose. Distant metastasis was also noted in many cases of early T-stage lesion, so to successfully manage the patient, careful evaluation of the metastasis is essential.

    To investigate whether the different location of pancreatic adenocarcinoma affects the lobar distribution of metastases to the liver. From all patients who underwent multidetector computed tomography (MDCT) examinations for staging of pancreatic adenocarcinoma in the last 4 years we selected 80 patients (42 men, 38 women; mean age, 60.56 years) with liver metastases and a pancreatic adenocarcinoma of the head (group A, 40 patients; diameter, 32.41 ± 2.28 mm) or body-tail (group B, 40 patients; diameter, 52.21 ± 2.8 mm). We analysed tumour site, diameter, vascular invasion and number of metastases in each lobe of the liver. The total number of metastases was compared between the two groups with an unpaired t-test, while Fisher's test was used to compare the number of metastases within the two lobes. As expected, the number of liver metastases was higher in group B than in group A. The ratio of metastases in the right-to-left hemi-liver was 7.4:1 for group A compared with 3.3:1 for group B (p < 0.0001). Although the number of liver metastases is higher in the right lobe than in the left lobe in both groups, there is a significant difference in the ratio of metastases between the right and the left hemi-liver. This supports the existence of a streamline phenomenon and a selective lobar distribution of metastases within the liver. (orig.)

    Objective: To present computed tomography findings observed in four patients submitted to radical nephrectomy for renal cell carcinoma who developed pancreatic metastases afterwards. Materials and methods: The four patients underwent radical nephrectomy for stage Tz1 (n=2) and stage T3a (n=2) renal cell carcinoma. The mean interval between nephrectomy and detection of pancreatic metastases was eight years. Two asymptomatic patients presented with solitary pancreatic metastases (confined to the pancreas). Two symptomatic patients presented with single and multiple pancreatic metastases, both with tumor recurrence in the contralateral kidney. Results: Computed tomography studies demonstrated pancreatic metastases as solitary (n=2), single (n=1) or multiple (n=1) hypervascular lesions. Partial pancreatectomy was performed in two patients with solitary pancreatic metastases and both are free of disease at four and two years after surgery. Conclusion: Pancreatic metastases from renal cell carcinoma are rare and can occur many years after the primary tumor presentation. Multiple pancreatic metastases and pancreatic metastases associated with tumor recurrence in the contralateral kidney are uncommon. Usually, on computed tomography images pancreatic metastases are visualized as solitary hypervascular lesions, simulating isletcell tumors. Surgical management should be considered for patients with solitary pancreatic lesions. (author)

    2018-01-01

    Full Text Available Skin metastases from advanced colorectal cancer are relatively rare and occur most often when the cancer is advanced, following the spread to other organs. Cutaneous metastases occur in about 3% of advanced colorectal cancers. We present an extremely rare case of a 68-year-old woman with advanced ascending colon adenocarcinoma that presented with multiple rapidly progressing painless cutaneous metastatic lesions with no other distant metastases. Of all the tumors, breast cancer most commonly spreads as cutaneous metastasis is followed by lung, colorectal, renal, ovarian, and bladder cancers. Cutaneous metastases can present in a variety of clinical manifestations, such as a rapidly growing painless dermal or subcutaneous nodule with intact overlying epidermis or as ulcers. In cases where the cutaneous deposit is isolated, as in visceral metastasis, there is a role for radical management such as wide local excision and reconstruction. In our patient, since she had multiple cutaneous metastases she began treatment with palliative systemic combination chemotherapy.

    Full Text Available The purpose and the objectives of the study were to determine the incidence of metastatic lesions to various parts of the spine, the assessment of the association with other clinical signs of lung cancer (localization, form, histology, degree of differentiation, staging, nature of extraosseous metastasis, to investigate the effect of these parameters on the survi­val of the patients. Material and methods. The study included 1071 patients with lung cancer aged 24 to 86 years. None of the examined patients has been operated previously for lung cancer, and after arriving at a diagnosis, all patients received radiation therapy, 73 % of them — combined radiochemothe­rapy. Results. Metastasis in the vertebral bodies and vertebral joints occurs in 13 % of patients with lung cancer and in 61 % of patients with bone form of the disease, the ratio of the defeat of thoracic, sacral, lumbar and cervical spine was 6 : 4 : 2 : 1. The development of metastases in the spine is mostly associa­ted with the localization of the tumor in the upper lobe of the lung, the peripheral form of the disease, with non-small cell histologic variants (adenocarcinoma and squamous cell carcinoma. The number of metastases in the spinal column directly correlates with the degree of metastatic involvement of the inguinal lymph nodes, abdominal wall and the liver, has an impact on the invasion of lung tumor into the esophagus and the trachea. The life expectancy of the deceased persons with spine metastases is less than that of other patients with the lung cancer, but the overall survival rate in these groups of patients is not very different. Conclusions. Clinical features of lung cancer with metastases in the spine necessitate the development of medical technology of rational radiochemotherapy in such patients.

    Median OS after surgery in curative intent for non-metastasized pancreas cancer ranges under study conditions from 17.9 months to 23.6 months. Tumor recurrence occurs locally, at distant sites (liver, peritoneum, lungs), or both. Observational and autopsy series report local recurrence rates of up to 87% even after potentially “curative” R0 resection. To achieve better local control, neoadjuvant CRT has been suggested for preoperative tumour downsizing, to elevate the likelihood of curative, margin-negative R0 resection and to increase the OS rate. However, controlled, randomized trials addressing the impact of neoadjuvant CRT survival do not exist. The underlying hypothesis of this randomized, two-armed, open-label, multicenter, phase III trial is that neoadjuvant CRT increases the three-year overall survival by 12% compared to patients undergoing upfront surgery for resectable pancreatic cancer. A rigorous, standardized technique of histopathologically handling Whipple specimens will be applied at all participating centers. Overall, 410 patients (n = 205 in each study arm) will be enrolled in the trial, taking into regard an expected drop out rate of 7% and allocated either to receive neoadjuvant CRT prior to surgery or to undergo surgery alone. Circumferential resection margin status, i.e. R0 and R1 rates, respectively, surgical resectability rate, local and distant disease-free and global survival, and first site of tumor recurrence constitute further essential endpoints of the trial. For the first time, the NEOPA study investigates the impact of neoadjuvant CRT on survival of resectable pancreas head cancer in a prospectively randomized manner. The results of the study have the potential to change substantially the treatment regimen of pancreas cancer.

    Schmid, K W

    2015-11-01

    The different biological features of the various major entities of thyroid cancer, e.g. papillary, follicular, poorly differentiated, anaplastic and medullary, depend to a large extent on their different metastatic spread. Papillary thyroid cancer (PTC) has a propensity for cervical lymphatic spread that occurs in 20-50 % of patients whereas distant metastasis occurs in thyroid cancer (FTC) has a marked propensity for vascular but not lymphatic invasion and 10-20 % of FTC develop distant metastases. At the time of diagnosis approximately one third of medullary thyroid cancer (MTC) cases show lymph node metastases, in 10-15 % distant metastases and 25 % develop metastases during the course of the disease. Poorly differentiated (PDTC) and anaplastic thyroid cancer (ATC) spread via both lymphatic and vascular invasion. Thus distant metastases are relatively uncommon in DTC and when they occur, long-term stable disease is the typical clinical course. The major sites of distant metastases are the lungs and bone. Metastases to the brain, breasts, liver, kidneys, muscle and skin are relatively rare or even rare. The thyroid gland itself can be a site of metastases from a variety of other tumors. In autopsy series of patients with disseminated cancer disease, metastases to the thyroid gland were found in up to 10 % of cases. Metastases from other primary tumors to the thyroid gland have been reported in 1.4-3 % of patients who have surgery for suspected cancer of the thyroid gland. The most common primary cancers that metastasize to the thyroid gland are renal cell (48.1 %), colorectal (10.4 %), lung (8.3 %) and breast cancer (7.8 %) and surprisingly often sarcomas (4.0 %).

    Carcinosarcoma of the prostate is an uncommon malignancy with poor long-term prognosis. The cancer is typically discovered at an advanced stage, and with less than 100 reported cases, there is limited literature concerning treatment options. Our patient presented with a history of benign prostatic hypertrophy, erectile dysfunction, and nocturia. Biopsy of his prostate indicated that the patient had prostatic adenocarcinoma, but histopathology after prostatectomy revealed carcinosarcoma. It has been over six years since this patient's diagnosis of carcinosarcoma. Over this span of time, he has received a radical prostatectomy, radiotherapy, and androgen ablative therapy. The patient also developed multiple lung metastases that have been treated with video-assisted thoracic surgery and stereotactic body radiosurgery. Overall, he has remained unimpaired and in good condition despite his aggressive form of cancer.

    A wide variety of architectural patterns of adenocarcinoma may be seen in the prostate. We have recently encountered a hitherto-undescribed pattern of growth characterized by intraluminal ball-like clusters of cancer cells reminiscent of renal glomeruli, which we refer to as prostatic adenocarcinoma with glomeruloid features. To define the architectural features, frequency, and distribution of prostatic adenocarcinoma with glomeruloid features, we reviewed 202 totally embedded radical prostatectomy specimens obtained between October 1992 and April 1994 from the files of the Mayo Clinic. This series was supplemented by 100 consecutive needle biopsies with prostatic cancer from January to February 1996. Prostatic adenocarcinoma with glomeruloid features was characterized by round to oval epithelial tufts growing within malignant acini, often supported by a fibrovascular core. The epithelial cells were sometimes arranged in semicircular concentric rows separated by clefted spaces. In the radical prostatectomy specimens, nine cases (4.5%) had glomeruloid features. The glomeruloid pattern constituted 5% to 20% of each cancer (mean, 8.33%) and was usually located at the apex or in the peripheral zone of the prostate. Seven cases were associated with a high Gleason score (7 or 8), one with a score of 6, and one with a score of 5. All cases were associated with high-grade prostatic intraepithelial neoplasia and extensive perineural invasion. Pathological stages included T2c (three cases), T3b (four cases), and T3c (two cases); one of the T3b cases had lymph node metastases (N1). Three (3%) of 100 consecutive routine needle biopsy specimens with cancer showed glomeruloid features, and this pattern constituted 5% to 10% of each cancer (mean, 6.7%). The Gleason score was 6 for two cases and 8 for one case. Two cases were associated with high-grade prostatic intraepithelial neoplasia, and one case had perineural invasion. Glomeruloid features were not observed in any benign or

    2009-08-01

    Full Text Available Abstract Background Metastases to the stomach from an extra-gastric neoplasm are an unusual event, identified in less than 2% of cancer patients at autopsy. The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung, or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also involve the stomach via lymphatic or haematogenous spread. We present three cases of secondary gastric malignancy. Methods/Results The first is a 19-year-old male who received a diagnosis of testicular choriocarcinoma in September 2004. Metastatic malignancy was demonstrated in the stomach after partial gastrectomy was performed to control gastric hemorrhage. The second is a 75-year-old male, generally well, who was diagnosed with adenocarcinoma of the lung in September 2005. Poorly differentiated adenocarcinoma of the lung was demonstrated in a subsequent biopsy of "gastric polyps". The third is an 85-year-old man with no known history of malignancy who presented for evaluation of iron deficiency anemia by endoscopy in February 2006. Biopsies of the colonic and gastric mucosa demonstrated moderately differentiated invasive colonic adenocarcinoma with metastatic deposits in the stomach. Conclusion While the accurate recognition of these lesions at endoscopy is fraught with difficulty, pathological awareness of such uncommon metastases in the gastric mucosa is essential for accurate diagnosis and optimal patient management.

    2007-01-01

    Metastatic paratesticular adenocarcinoma from the pancreatic cancer is very rare. To our knowledge, there are less than 20 cases published in the literature. We experienced a case of paratesticular adenocarcinoma from the primary pancreatic cancer. A 42-year-old man was presented with locoregionally advanced carcinoma of the tail of the pancreas with intraoperatively found liver metastases and with a tumour in the right hemi-scrotum. Ultrasound of the scrotum revealed a paratesticular tumour. A fine needle aspiration biopsy (FNAB) confirmed a poorly differentiated adenocarcinoma and it was in concordance with the diagnosis of the primary tumour. The patient started treatment with chemotherapy with gemcitabine. Unfortunately, he progressed one month later and the treatment was discontinued. Outcome in the adenocarcinoma of the pancreas is dismal. The only possible treatment option for metastatic disease is systemic therapy but the results are disappointing, as in the present case.

    Full Text Available Urachal carcinoma is a rare and aggressive form of bladder cancer involving the urachus, a fibrous remnant of the allantois that extends from the bladder to the umbilicus. We report this case of a 49-year-old women with primary urachal adenocarcinoma treated with partial cystectomy who relapsed 5 years after surgery with lung metastases. This patient with unremarkable medical history presented with abdominal discomfort and a palpable pelvic mass. Follow-up imaging reveals a large mass on the dome of the bladder extending from the urachus. Subsequent ultrasound-guided biopsy result was suggestive of an urachal mucinous adenocarcinoma. The patient was treated surgically with a partial cystectomy.

    1979-01-01

    Adenocarcinoma of the gallbladder developed in 17 of 68 untreated and in 26 of 83 irradiated guinea pigs of inbred strains 2 and 13. The carcinomas spread widely by direct extension and through lymphatic and blood vessels to lymph nodes, mesenteries, omenta, abdominal wall, liver, lungs, bones, and spleen. Whole-body exposure to gamma or x radiation increased both the number of tumors and metastases in male inbred guinea pigs but not in females. Significantly fewer (9 of 98) noninbred than inbred guinea pigs developed gallbladder carcinomas after irradiation. In 9 untreated noninbred guinea pigs gallbladder carcinomas were not found. Inasmuch as the effect of irradiation was not dose-dependent, an indirect systemic effect of irradiation was postulated. This is the first report on the occurrence of spontaneous gallbladder adenocarcinomas in guinea pigs

  19. SPECIAL FEATURES OF CARCINOGENESIS OF COLON ADENOCARCINOMA

    Directory of Open Access Journals (Sweden)

    G. A. Raskin

    2015-01-01

    Full Text Available Colorectal cancer is one of the most common malignancies and the leading cause of cancer-related death. There are 4 basic colon carcinogenic steps: malignant transformation of adenoma into carcinoma; HNPCC (hereditary nonpolyposis colon cancer; cancer «de novo»; chronic colitis malignant transformation. All of them, except for Lynch syndrome, are increasingly focused on stem tissue-committed cells as mutation targets and the source of malignancies. Subsequently, cancer stem cells are considered as the cause of chemoresistance of tumors, metastases and relapses. Thus, the study of the cell population can dramatically change approaches to the treatment of patients with colorectal adenocarcinoma.

  20. Diagnostic imaging of skeletal metastases

    2000-01-01

    Purpose of this article is to present an algorithm for detection and diagnosis of skeletal metastases, which may be applied differently in symptomatic and asymptomatic cancer patients. February to March 1999 it was randomly selected and retrospectively reviewed the clinical charts of 100 cancer patients (70 women and 30 men; mean age: 63 years, range: 55-87). All the patients had been staged according to TNM criteria and had undergone conventional radiography and bone scan; when findings were equivocal, CT and MRI had been performed too. The primary lesions responsible for bone metastases were sited in the: breast (51 cases), colon (30 cases: 17 men and 13 women), lung (7 cases: 6 men and 1 woman), stomach (4 cases: 2 men and 2 women), skin (4 cases: 3 men and 1 woman), kidney (2 men), pleura (1 woman), and finally liver (1 man). The most frequent radiographic pattern was the lytic type (52%), followed by osteosclerotic, mixed, lytic vs mixed and osteosclerotic vs lytic patterns. The patients were divided into two groups: group A patients were asymptomatic and group B patients had local symptoms and/or pain. Skeletal metastases are the most common malignant bone tumors: the spine and the pelvis are the most frequent sites of metastasis, because of the presence of high amounts of red (hematopoietic active) bone marrow. Pain is the main symptom, even though many bone metastases are asymptomatic. Pathological fractures are the most severe consequences. With the algorithm for detection and diagnosis of skeletal metastases two different diagnostic courses are available for asymptomatic and symptomatic patients. Bone scintigraphy remains the technique of choice in asymptomatic patients in whom skeletal metastases are suspected. However this technique, though very sensitive, is poorly specific, and thus a negative bone scan finding is double-checked with another physical examination: if the findings remain negative, the diagnostic workup is over. On the contrary, in

    Full Text Available Tumores primários de uretra são raros em animais e há poucos relatos em cães. A ocorrência é maior em cadelas idosas, não havendo predileção por raça. Disúria, estrangúria e hematúria são sinais clínicos associados a esses tumores. É relatado um caso de adenocarcinoma primário de uretra em um cadela Poodle de 12 anos de idade que apresentava aumento de volume no membro pélvico esquerdo. Na necropsia, foram encontradas metástases na articulação femorotibial esquerda, na glândula adrenal e no rim.Urethral primary tumors are rare in animals and there are only few reports in dogs. They are more frequent in old bitches and have no breed predilection. Clinical signs associated with urethral primary tumors include dysuria, strangury and hematuria. We report a case of primary urethral adenocarcinoma in a 12-year-old female Poodle that was presented with localized volume enlargement in the left pelvic limb. At necropsy metastasis were found at the left femorotibial joint, adrenal gland and kidney.

    Every year in Europe and in USA, more than 60% of new cases of cancer are diagnosed at the patient's of more than 65 years with a mortality of more than 70%. Pain, is a major symptom which often accompanies cancer. It is always painful and intolerable, notably when pain is linked to bone metastases to elderly patients often poly pathological. In 1/3 of cases pain is present at the time of diagnosis of cancer and in 2/3 of cases at the advanced diseases. The bone metastases occupy the third place after the pulmonary and liver metastases. They are in order of frequency linked in breast cancer, the kidney and the prostate cancer. Bone metastases are at the origin of the loss of the elderly autonomy, with for consequence an impairment of quality of life. Validated tools are at now available to assess this pain. The different treatments offered in bone metastases pain are: the chemotherapy, the surgery, radiotherapy, bisphosphonates and analgesic treatment.

    2014-01-01

    Full Text Available Malignant metastasis to the psoas muscle is rare. We report a case that clinically mimicked psoas abscess that was subsequently proven to be from metastatic disease secondary to adenocarcinoma of the duodenum. A 62-year-old male presented with a seven-month history of right lower quadrant abdominal pain and progressive dysphagia. CT scan of abdomen-pelvis revealed a right psoas infiltration not amenable to surgical drainage. Patient was treated with two courses of oral antibiotics without improvement. Repeated CT scan showed ill-defined low-density area with inflammatory changes involving the right psoas muscle. Using CT guidance, a fine needle aspiration biopsy of the right psoas was performed that reported metastatic undifferentiated adenocarcinoma. Patient underwent upper endoscopy, which showed a duodenal mass that was biopsied which also reported poorly differentiated adenocarcinoma. In this case, unresponsiveness to medical therapy or lack of improvement in imaging studies warrants consideration of differential diagnosis such as malignancy. Iliopsoas metastases have shown to mimic psoas abscess on their clinical presentation and in imaging studies. To facilitate early diagnosis and improve prognosis, patients who embody strong risk factors and symptoms compatible with underlying malignancies who present with psoas imaging concerning for abscess should have further investigations.

    Adenocarcinoma of the ethmoid sinus is rare, representing only 4 to 8% of malignancies of the paranasal sinuses. An extraordinary case of papillary adenocarcinoma of the ethmoid sinus arising 30 years following high-dose radiotherapy for bilateral retinoblastoma is presented. Second fatal mesenchymal and epithelial primaries have been described in 8.5% of patients with bilateral retinoblastomas previously treated with radiotherapy; however, papillary adenocarcinoma arising within the paranasal sinuses has not been reported. Aggressive treatment including partial maxillectomy, radical pansinusectomy, radical neck dissection followed by regional radiotherapy and systemic chemotherapy failed to prevent the development of fatal hepatic metastases. The high incidence of second fatal primary neoplasms in patients with bilateral retinoblastomas receiving radiation suggests an innate susceptibility that may add to the risk of radiotherapy.

    Splenic metastases from solid tumors are a rare event with an incidence of only 2.9% to 9%. Splenic metastases from cervical cancer are a rare entity. Only a few cases have been reported of isolated spleen metastases from cervical cancer. We present the case of a 76-year-old woman with moderately differentiated endocervical adenocarcinoma stromal and endocervical invasion. Clinical stage was Ib1 and Ca-125 values of 150 U. She was managed with hysterectomy and pelvic lymphadenectomy. She received pelvic radiotherapy (45 Gy) followed 24 Gy of brachytherapy. Two years later she presented with abdominal pain. Abdominal computed tomography showed two splenic parenchymal lesions without disease in the remainder of the abdominal cavity and chest with a Ca-125 of 2,733 U. The patient is submitted to splenectomy. Histopathology demonstrates splenic metastases of well-differentiated adenocarcinoma from the endocervix. Immunohistochemical stain showed positivity from carcinoembryonic antigen; estrogen and progesterone receptors are negative. Ca-125 level 8 weeks after surgery was 16 U/ml. The patient received six cycles of adjuvant chemotherapy with paclitaxel and cisplatin. At 12 months follow-up the patient is alive and without evidence of tumor activity. The spleen is an uncommon site of metastasis. Splenectomy is considered the appropriate treatment in order to avoid complications such as splenic rupture and splenic vein thrombosis as well as to improve pain control from splenomegaly. Twelve months after surgery our patient is alive and without evidence of tumor activity.

    Full Text Available Abstract Uveal melanoma (UM is the most prevalent intraocular malignant tumor in the Western world. The prognosis of survival in the presence of metastatic disease is 2-7 months, depending on the treatment applied. This article presents a case of metastatic UM with successful complex treatment of liver metastases. A 49-year old female, underwent removal of the right eyeball in 1996 due to a histologically confirmed uveal melanoma. After 11 years, CT revealed a mass in the left kidney and multiple metastases in the liver. After left nephrectomy, 6 chemotherapy courses with dacarbazine were performed. The increasing liver metastases were observed. Additional 4 intraarterial (i/a chemotherapy courses were administered using cisplatin, doxorubicin, fluorouracil, and interferon alfa. After few courses increase in CTC Grade 4 liver transaminases was seen. A partial response was observed, and in December 2008 the patient underwent surgery removing all liver metastases by 7 wedge or atypical resections. All margins were tumor-free. 21 months after liver resections and 14 years since diagnosis, the patient is alive without evidence of disease. Successful treatment of metastatic uveal melanoma was due to a timely application of a combination of several treatment methods and good prognostic factors of the patient.

  14. Is dual-phase abdominal CT necessary for the optimal detection of metastases from renal cell carcinoma?

    International Nuclear Information System (INIS)

    Jain, Y.; Liew, S.; Taylor, M.B.; Bonington, S.C.

    2011-01-01

    Aim: To determine whether dual-phase abdominal computed tomography (CT) detected more metastases than portal-phase CT alone in patients with renal cell carcinoma (RCC). Materials and methods: Audit committee approval was obtained. A retrospective audit was undertaken in 100 patients who underwent both arterial and portal phase CT. The CT images were independently reviewed by two consultant radiologists. The presence of metastases in the liver, pancreas, and contralateral kidney were recorded for each phase of contrast enhancement. Results: Metastases were identified in the liver in 27 patients, pancreas in 12, and contralateral kidney in 23 patients. Nine of the 27 (33%) liver metastases, three of the 12 (25%) pancreatic metastases, and two of the 23 (9%) renal metastases were only detected in the arterial phase, whilst four of the 27 (15%) liver metastases, three of the 12 (25%) pancreatic metastases, and two of the 23 (9%) renal metastases were only detected in the portal phase. Nine patients (9%) had metastases only visualized in the arterial phase, and six (6%) only in the portal phase. Detection of metastases only visible in the arterial phase led to a change of management in two patients (2%). Conclusion: The audit results support our current standard of dual-phase abdominal CT for optimal detection of RCC metastases.

    Cardiac smooth muscle tumors are rare. Three different clinical settings for these tumors have been reported, including benign metastasizing leiomyoma from the uterus, primary cardiac leiomyoma and leiomyosarcoma, and intravenous cardiac extension of pelvic leiomyoma, which is the most common. We present a case of a 55-year-old woman with a benign metastasizing leiomyoma to the heart 17 years after hysterectomy and 16 years after metastasis to the lung. Immunohistochemical stains for smooth muscle actin, desmin, and estrogen and progesterone receptors were positive, indicating a smooth muscle tumor of uterine origin. To our knowledge, this is only the fourth reported case of benign metastasizing leiomyoma to the heart and the first case of long-delayed cardiac metastasis after successful treatment of pulmonary metastasis. It illustrates that benign metastasizing leiomyoma should be included in the differential diagnosis of cardiac tumors in patients with a history of uterine leiomyoma, especially when associated with pulmonary metastasis.

    The authors present the changes in the immune system in tumor-bearing hosts that may influence the development of progression of metastases. Included are mononuclear cell infiltration of metastases; alterations in natural resistance mediated by natural killer cells and macrophages; development of specific immunity mediated by T-lymphocytes or antibodies; modulation of tumor-associated antigen expression; and the down-regulation of the immune response to the tumor by several suppressor mechanisms; the augmentation of the immune response and its potential for therapeutic application; includes the prophylaxis of metastases formation by NK cells; the therapy of metastases by augmentation NK-, macrophage-, or T-lymphocyte-mediated responses by biological response modifiers; and the transfer of anticancer activity by cytoxic T-lymphocytes or immunoconjugates of monoclonal antibodies with specificity for tumors

    Alpha-fetoprotein is a well-known tumor marker in the screening and follow-up of hepatocellular carcinoma. In Taiwanese society, a high prevalence of hepatitis and hepatoma and elevation of alpha-fetoprotein associated with liver function impairment usually suggested clinics undertake further examination for liver or genital tumor. We report the case of 45-year-old man who was found to have an alpha-fetoprotein-producing esophageal adenocarcinoma with an initial presentation of liver function impairment and rapid elevation of alpha-fetoprotein. Esophageal cancer was diagnosed via endoscope and a biopsy proved the presence of adenocarcinoma. A small endoscopic biopsy specimen failed to identify the alpha-fetoprotein positive tumor cell. Esophagectomy was performed and histopathological study of surgical specimen revealed grade II adenocarcinoma with regional metastatic lymphadenopathy. Immunohistochemical study was focal positive for alpha-fetoprotein. Serum alpha-fetoprotein declined transiently after esophagectomy and fluctuation of alpha-fetoprotein level was noted during the treatment with adjuvant chemotherapy. Finally, 19 months after the operation, the patient died due to multiple organ metastases with multiple organ failure. Thus, a small specimen for upper endoscopy may not be sufficient in the presence of alpha-fetoprotein-producing adenocarcinoma. Monitoring of serum alpha-fetoprotein may be useful in the evaluation and follow-up of esophageal alpha-fetoprotein-producing adenocarcinoma. Copyright © 2012. Published by Elsevier B.V.

    Background. Brain metastases are common patterns of dissemination in lung cancer patients. In this paper we would like to assess the pattern of brain metastases in lung cancer patients and the impact of prognostic factors on the survival of lung cancer patients with brain metastases. Patients and methods. In the year 1998 there were 974 registered patients with lung cancer in Slovenia, six hundred and fifteen of them were treated at the Institute of Oncology Ljubljana and we analyzed them. Among 615 patients 137 (22.3 %) of them have had brain metastases during a natural course of disease. Results. For 12 patients presenting with solitary brain metastases (most of them were undertaken metastasectomy) median survival was 7.6 months, while in patients with multiple brain metastases the median survival was 2.8 months (p 0.0018). Of the 137 patients 45 (32.8 %) were small cell lung cancer patients, 43 (31.4 %) were adenocarcinoma patients and 19 (13.9 %) were squamous cell carcinoma patients. Patients with performance status (WHO scale) less than 2 had the median survival time 3.7 months while patients with performance status 2 or more had median survival time 2.7 moths (p=0.0448). Conclusions. Patients with solitary brain metastases had better survival comparing with those who had multiple metastases. It is surprisingly that the portion of brain metastases patients with adenocarcinoma is almost equal to those with small-call lung cancer therefore, the prophylactic cranial radiation becomes actual for both groups of patients. The performance status of patients with brain metastases remains very important prognostic factor. (author)

  19. Lymphoma and metastases in the urinary tract

    Bruneton, J.N.; Drouillard, J.

    1989-01-01

    Kidneys lymphomas are mainly secondary and represent the most frequent localizations in the urinary tract (68%). The appearance most frequently observed with computed tomography (CT) as well as ultrasound is that of multinodular involvement or, less frequently, of contiguous involvement from retroperitoneal adenopathy in an isolate nodular or tumoral form or in an infiltrating form. The lesions are most often bilateral and involve the lymph nodes, the liver and/or the spleen, especially when the tumor is a metastasis. Lymphoma in the excreting cavities of the bladder is much less frequent. The frequent stasis does no allow obtaining satisfactory urograms for the exploration of the ureters, so that antegrade or retrograde pyelography is often necessary. The lesions of the bladder are well demonstrated by ultrasound and CT exploration. The metastases of lymphoma in the urinary tract are most frequently located in the kidneys, and represent the most frequent malignant kidney tumors. They are often non recognized clinically since they occur at late stages in cancer evolution. Their usual appearance with ultrasound and CT is that of multiple solid-type tumors. Metastases in the excreting cavities of the bladder are very rare [fr

    Full Text Available Abstract Background Natural killer (NK cells represent a first line of defence against a developing cancer; however, their exact role in colorectal cancer remains undetermined. The aim of the present study was to evaluate the expression of CD16 and CD57 [immunohistochemical markers of natural NK cells] in colorectal adenocarcinoma. Methods Presence of NK cells was investigated in 82 colorectal adenocarcinomas. Immunohistochemical analysis was performed, using 2 monoclonal antibodies (anti-Fc Gamma Receptor II, CD16 and an equivalent to Leu-7, specific for CD-57. The number of immunopositive cells (% was evaluated by image analysis. The cases were characterized according to: patient gender and age, tumor location, size, grade, bowel wall invasion, lymph node metastases and Dukes' stage. Results NK cells were detected in 79/82 cases at the primary tumor site, 27/33 metastatic lymph nodes and 3/4 hepatic metastases; they were detected in levels similar to those reported in the literature, but their presence was not correlated to the clinical or pathological characteristics of the series, except for a negative association with the patients' age (p = 0.031. Conclusions Our data do not support an association of NK cell tissue presence with clinical or pathological variables of colorectal adenocarcinoma, except for a negative association with the patients' age; this might possibly be attributed to decreased adhesion molecule expression in older ages.

    1987-01-01

    A series of 243 patients with adenocarcinoma of the rectum treated with radiotherapy is presented. Radiotherapy was combined with 5-fluorouracil, or given alone. Seventy-four patients were treated with radical external beam radiotherapy for recurrent or inoperable rectal adenocarcinoma. One hundred and forty-five patients with advanced pelvic tumours or metastases were treated with palliative pelvic radiotherapy. Twenty-four patients with small-volume residual pelvic tumour or who were felt to be at high risk of pelvic recurrence following radical resection received postoperative radiotherapy. Complete tumour regression was seen in 38% of radically treated patients, and 24% of palliatively treated patients. Partial regression was observed in 56% of radically treated patients, and 58% of palliatively treated patients. Long-term local tumour control was more commonly observed for small tumours (< 5 cm diameter). Fifty-eight % of patients treated with postoperative radiotherapy remained free of local recurrence. Survival was significantly better with small tumours. The addition of 5FU did not appear to improve survival or tumour control. (author)

    Advances in neurosurgery and the development of stereotactic radiosurgery have expanded treatment options available for patients with brain metastases. However, despite several randomized clinical trials and multiple uncontrolled studies, there is not a uniform consensus on the best treatment strategy for all patients with brain metastases. The heterogeneity of this patient population in terms of functional status, types of underlying cancers, status of systemic disease control, and number and location of brain metastases make such consensus difficult. Nevertheless, in certain situations, there is Class I evidence that supports one approach or another. The primary objectives in the management of this patient population include improved duration and quality of survival. Very few patients achieve long-term survival after the diagnosis of a brain metastasis.

    2011-01-01

    Full Text Available Metastasis of uterine cancer to the head and neck is extremely rare. We report what we believe to be the first documented case of endometrioid adenocarcinoma metastasizing to the thyroid gland. An 80-year-old woman was referred to the otolaryngology service with a rapidly growing neck mass. The mass appeared to originate from the thyroid gland. Her clinical presentation was consistent with anaplastic thyroid carcinoma. A tracheostomy was performed. An open biopsy established the diagnosis of moderately differentiated adenocarcinoma, consistent with a gynecologic primary. The patient had undergone a hysterectomy 5 years prior for endometrioid adenocarcinoma. The thyroid tumor histology and immunophenotype corresponded well with her prior endometrial carcinoma, indicating that the thyroid mass was a metastasis from the endometrial primary. Radiotherapy appears to offer good local disease control in this rare case of endometrioid adenocarcinoma metastatic to the thyroid.

    Purpose/Objectives: Evidence from the management of oligometastases with stereotactic body radiation therapy (SBRT) reveals differences in outcomes based on primary histology. We have previously identified a multigene expression index for tumor radiosensitivity (RSI) with validation in multiple independent cohorts. In this study, we assessed RSI in liver metastases and assessed our clinical outcomes after SBRT based on primary histology. Methods and Materials: Patients were identified from our prospective, observational protocol. The previously tested RSI 10 gene assay was run on samples and calculated using the published algorithm. An independent cohort of 33 patients with 38 liver metastases treated with SBRT was used for clinical correlation. Results: A total of 372 unique metastatic liver lesions were identified for inclusion from our prospective, institutional metadata pool. The most common primary histologies for liver metastases were colorectal adenocarcinoma (n=314, 84.4%), breast adenocarcinoma (n=12, 3.2%), and pancreas neuroendocrine (n=11, 3%). There were significant differences in RSI of liver metastases based on histology. The median RSIs for liver metastases in descending order of radioresistance were gastrointestinal stromal tumor (0.57), melanoma (0.53), colorectal neuroendocrine (0.46), pancreas neuroendocrine (0.44), colorectal adenocarcinoma (0.43), breast adenocarcinoma (0.35), lung adenocarcinoma (0.31), pancreas adenocarcinoma (0.27), anal squamous cell cancer (0.22), and small intestine neuroendocrine (0.21) (P<.0001). The 12-month and 24-month Kaplan-Meier rates of local control (LC) for colorectal lesions from the independent clinical cohort were 79% and 59%, compared with 100% for noncolorectal lesions (P=.019), respectively. Conclusions: In this analysis, we found significant differences based on primary histology. This study suggests that primary histology may be an important factor to consider in SBRT radiation dose selection.

The 12-month and 24-month Kaplan-Meier rates of local control (LC) for colorectal lesions from the independent clinical cohort were 79% and 59%, compared with 100% for noncolorectal lesions (P=.019), respectively. Conclusions: In this analysis, we found significant differences based on primary histology. This study suggests that primary histology may be an important factor to consider in SBRT radiation dose selection.

    Full Text Available Gastric carcinoma is extremely rare in children representing only 0.05% of all gastrointestinal malignancies. Here, we report the first pediatric case of gastric cancer presenting with gastric outlet obstruction. Upper endoscopy revealed a markedly thickened antral mucosa occluding the pylorus and a clean base ulcer 1.5 cm × 2 cm at the lesser curvature of the stomach. The narrowed antrum and pylorus underwent balloon dilation, and biopsy from the antrum showed evidence of Helicobacter pylori gastritis. The biopsy taken from the edge of the gastric ulcer demonstrated signet-ring-cell type infiltrate consistent with gastric adenocarcinoma. At laparotomy, there were metastases to the liver, head of pancreas, and mesenteric lymph nodes. Therefore, the gastric carcinoma was deemed unresectable. The patient died few months after initiation of chemotherapy due to advanced malignancy. In conclusion, this case report underscores the possibility of gastric adenocarcinoma occurring in children and presenting with gastric outlet obstruction.

    Full Text Available A sixty-one year old man was referred with a history of progressive dysphagia, vomiting and weight loss with some back pain. Upper gastrointestinal endoscopy and biopsies revealed a gastro-oesophageal junction adenocarcinoma. Despite the absence of metastatic disease on computed tomography, positron emission tomography demonstrated multiple vertebral and sternal deposits. He was reviewed in an ENT clinic with a sudden onset of hearing loss accompanied by dizziness, but no focal neurology. Magnetic resonance imaging identified bilateral 2cm lesions at the internal auditory meatus, consistent with a diagnosis of bilateral acoustic neuromas. The patient subsequently died of carcinomatosis and, because of the potential familial significance of bilateral acoustic neuromas, a limited post-mortem examination was carried out. Unexpectedly, this revealed bilateral adenocarcinoma metastases infiltrating the internal auditory meatus affecting the acoustic nerves. The authors believe this a very rare presentation of metastatic gastric disease.

    2014-11-01

    Full Text Available Primary adenocarcinoma of the vermiform appendix is the least common carcinoma of this organ; its exact frequency is unknown. Primary malignant tumors of the appendix are rare; they are generally found in 1 to 2% of all appendices examined. Most appendiceal malignancies arise from a primary tumor in the adjacent organs, and in some cases, may be metastases from distant tumors. The case of a 43-year-old patient with a history of emergency surgery who was presumptively diagnosed with acute appendicitis is presented. The presence of an adenocarcinoma at the base of the appendix was reported by the pathology department. Because of the rarity of the condition, the publication of this case is considered scientifically important.

    Full Text Available Localized gingival enlargement is often associated with specific systemic medication, abscess formation, trauma or reactive lesions. Scant literature is available reporting enlargement of gingiva due the metastasis of adenocarcinoma from lung. The case report presents a unique case of an adenocarcinoma in the lung metastasizing to the buccal and lingual interdental papillae of teeth numbering 34 and 35. A 72-year-old female was referred to the Mayo Clinic with a recent diagnosis of metastatic stage IV adenocarcinoma of the left lung presented with an abnormal mass located on the left posterior buccal keratinized tissue adjacent to teeth numbering 34-35. Biopsy of the lesion was performed for CK7, CK20, TTF-1 and p63. The tumor cells were positive for CK7 and TTF-1, and weakly positive for p63 suggesting a diagnosis of adenocarcinoma. The periodontist may be in the unique position to be the first oral health care provider to evaluate any biopsy suspicious intra-oral lesions.

    Less than 3% of all breast cancers originate from a primitive extra mammary. In 40% of cases it is the first manifestation of the primitive properly studied but 80% are associated with widely disseminated disease. It typically presents as a nodule on external quadrant s painful in half the cases. The majority (60%) of metastases derived from breast contralateral breast tumors are believed to via the lymphatic system. of the ; extra mammary the most common tumors are melanoma; hematologic and neuroendocrine. Although some imaging characteristics can guide diagnosis is histological. Cytology has good performance in experienced hands; but up to 25% of cases there may be difficulty in establishing diagnosis. Treatment depends on the type of tumor. Mastectomy should not be practiced or axillary clearance routine as is generally the context of disease disseminated. Radiation therapy may be useful for local control. It has been proposed laser ablation but no experience with it. The overall prognosis is bad. For a man of 45 with a breast metastasis occurs only a clear cell carcinoma of the kidney

    An 82-year-old man presented with progressive right frontal headaches. The patient's history was significant for benign polyps on surveillance colonoscopy 2 years prior, without high-grade dysplasia or carcinoma. MRI revealed an enhancing lesion arising within the superomedial aspect of the right orbit. Lesion biopsy demonstrated histological appearance and immunophenotype suggestive of colonic adenocarcinoma. Staging positron emission tomography/CT showed visceral metastases and diffuse activity in the posterior rectosigmoid, consistent with metastatic colon cancer. Treatment of the orbital lesion with external beam radiotherapy to 30 Gy resulted in significant palliation of the patient's headaches. The patient expired 2 months following treatment completion due to disease progression. Orbital metastasis as the initial presentation of an occult colorectal primary lesion is exceedingly rare, and occurred in this patient despite surveillance colonoscopy. Radiotherapy remains an efficacious modality for treatment of orbital metastases. 2014 BMJ Publishing Group Ltd.

    2010-11-01

    Full Text Available We present a 60-year old woman with recurrent cervical adenocarcinoma who presented with metastasis to both lungs and to her right adrenal gland. A thoracotomy was performed for resection of her pulmonary metastasis and then the right adrenal gland was excised through a trans-diaphragmatic approach. The adrenal gland resection was more complex due to involvement of the tumor with the inferior vena cava (IVC which was repaired with a PTFE patch graft. This case demonstrates both an interesting approach to surgical resection of multiple metastases as well as a safe, although more challenging, alternative to partially resect and repair the IVC.

    ABSTRACT: A 72-year-old man presented with a two month history of rectal bleeding. Colonoscopy demonstrated synchronous lesions at 3 cm and 40 cm with histological analysis confirming synchronous adenocarcinomata. He developed bilobar hepatic metastases while undergoing neoadjuvant chemoradiotherapy. Treatment was complicated by Fournier\\'s gangrene of the right hemiscrotum which required surgical debridement. Eight months later he re-presented with an ulcerating lesion on the right hemiscrotum. An en-bloc resection of the ulcerating scrotal lesion and underlying testis was performed. Immunohistological analysis revealed metastatic adenocarcinoma of large bowel origin. Colorectal metastasis to the urogenital tract is rare and here we report a case of rectal carcinoma metastasizing to scrotal skin.

    With binocular indirect ophthalmoscopy, fluorescin angiography and ultrasonography 68 choroidal metastases in 52 eyes of 39 patients were diagnosed. The primary tumors were mainly breast cancer (81%) and lung cancer (10%). After radiation treatment the visual acuity improved in 17 eyes (38%), stabilized in 15 eyes (33%), whereas in 13 eyes (29%) deterioration could not be prevented (seven eyes unknown). Regression of the lesions or its accompanying secondary retinal detachment was seen in 78% of the eyes treated. Acute transient side effects of radiation therapy were keratoconjunctivitis (nine patients) and acute glaucoma in one patient. No cataractous changes of the lens were observed in the post radiation period (one to 42 months). Irradiation of choroidal metastases can contribute to improvement of the quality of life with a treatment scheme of 30 Gy in ten daily fractions.

    The diagnosis of intravascular metastatic tumor emboli to the lungs is rarely made. The authors present a characteristic radiographic finding of intravascular lung metastases that they observed in four patients with diagnoses or right atrial myoxoma, invasive renal cell carcinoma, invasive pelvic osteosarcoma, and recurrent pelvic chondrosarcoma. Substantiation of intravascular pulmonary metastases was achieved by means of autopsy, pulmonary artery biopsy, and surgical documentation of tumor invasion of the inferior vena cava or pelvic veins. In all four cases, chest computed tomography (CT) demonstrated branching, beaded opacities extending from the hila into the periphery of the lung in the distribution of pulmonary arteries. In one case, similar findings were observed in magnetic resonance (MR) images of the chest. Follow-up studies in three cases showed progressive enlargement and varicosity of the abnormal pulmonary artery consistent with proliferation of intravascular tumor. In the case of metastatic osteosarcoma, intraluminal ossification was also observed at CT. In three of four cases, pulmonary infarction was demonstrated in the distribution of the abnormal pulmonary arteries seen at CT as small, peripheral, wedge-shaped opacities. The demonstration of progressively dilated and beaded pulmonary arteries in patients with extrathoracic malignancies is suggestive of intravascular lung metastases, particularly when accompanied by peripheral infarction

  5. Bone scintiscanning in metastases

    1986-01-01

    The three fold interest of bone scintiscanning is discussed in relation to 182 cases of bone metastases of various origins. Firstly, this technic facilitates early diagnosis of invasion of the bone by the detection of metastatic lesions which, in 7.7% of cases are still infraradiologic, or even of reflex algodystrophy of the legs, which can be detected only from a scintiscan, long before X-ray plates can show the lumbar metastasis which is responsible. Secondly, the method is able to pick up more metastasic sites in 54.4% of cases than can be detected by X-ray; this is confirmed by investigation of the S/R ratio (ratio of the number of strongly binding sites to the number of sites showing radiologic damage) which is greater than unity for a considerable period. Thirdly, repeated scintiscanography provides a prognosis, because the survival time appears to be fairly closely correlated with the regression, stability or extension of strongly binding sites, although a ''flare phenomenon'' may give the erroneous impression that the metastatic process has deteriorated. Repeated scintiscanography also provides a good way of evaluating the efficacy of medical treatment, particularly in the case of bone metastases of mammary or prostatic origin. Sometimes, the decision for or against prophylactic or palliative orthopedic surgery may be based to a considerable extent on data provided by scintiscan [fr

    1984-01-01

    To determine the role of brain CT in neurologically asymptomatic lung cancer patients a review was made of the CT and clinical findings in 279 patients. Brain metastases were found in 94.5% of patients with specific abnormal neurological findings, 26.6% of patients with vague neurological signs and symptoms, 11% of patients with oat cell carcinoma and a normal neurological examination, and 40% of patients with adenocarcinoma and a normal neurological examination. Brain metastasis was not seen on CT in the 29 patients with squamous cell carcinoma and a normal neurological examination. It is concluded that brain CT is useful for the detection of occult brain metastases, particularly oat cell carcinoma and adenocarcinoma, in neurologically asymptomatic lung cancer patients

    Full Text Available Medulloblastoma is the most common childhood malignant tumor of central nervous system, but it may also occur in adults. It presents high invasive growth with spreading of tumor cells into the leptomeningeal space along the neuroaxis early in the course of the disease. Extraneural metastases are rare but frequently lethal, occurring only in 1 to 5% of patients, and are related, in the most of cases, to the presence of ventriculoperitoneal shunt. Here we characterize the clinical profile of five cases of medulloblastoma with systemic spreading of tumor cells, also comparing them to cases already described in the literature.

    Full Text Available Metastatic adenocarcinoma to the breast from an extramammary site is extremely rare. In the literature, the most current estimate is that extramammary metastases account for only 0.43% of all breast malignancies and that, of these extramammary sites, colon cancer metastases form a very small subset. Most commonly seen metastasis in breast is from a contralateral breast carcinoma, followed by metastasis from hematopoietic neoplasms, malignant melanoma, sarcoma, lung, prostate, and ovary and gastric neoplasms. Here we present two rare cases, in which colonic adenocarcinomas were found to metastasize to the breast. In both cases, core biopsies were obtained from the suspicious areas identified on mammogram. Histopathology revealed neoplastic proliferation of atypical glandular components within benign breast parenchyma which were morphologically consistent with metastatic adenocarcinoma. By immunohistochemical staining, it was confirmed that the neoplastic components were immunoreactive to colonic markers and nonreactive to breast markers, thus further supporting the morphologic findings. It is extremely important to make this distinction between primary breast cancer and a metastatic process, in order to provide the most effective and appropriate treatment for the patient and to avoid any harmful or unnecessary surgical procedures.

    Objective: To study the correlation between the level of serum tumor makers and bone metastases of lung cancer. Method: In 128 diagnosed patients with lung cancer, small cell lung cancer were 26 cases, non-small cell lung cancer were 102 cases which included 44 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 4 cases of large cell carcinoma, 4 cases of squamous adenocarcinoma. "9"9"mTc-MDP whole-body bone scanning was performed in 128 patients with lung cancer. over the same period, the serum samples were collected in these patients and 30 comparison controls. CEA, CA125, CA199, SCC, NSE, CA15-3, and AFP were measured by ELISA technique. Bone imaging findings analysis used t-test, and serum levels of tumor markers analysis used χ"2 test. Results: The diagnostic of 53 cases of lung cancer with bone metastasis was subject to clinical criteria of lung cancer with bone metastases. The positive ratio of patients with osseous metastasis was confirmed by "9"9"mTc-MDP whole-body bone scanning was 23.44% (30/128), including 16 cases of lung adenocarcinoma, 9 cases of squamous cell carcinoma, 3 cases of small cell lung cancer , 1 case of large cell lung cancer, 1 case of squamous adenocarcinoma and multiple bone metastases accounted for 66.67% (20/30). The levels of serum CEA, CA125, CA199, SCC, NSE and CA15-3 were higher than the control group (P < O.05). 29 cases of CEA positive and 21 cases of CA125 positive were included in 30 cases of lung cancer with bone metastasis. There was a significant difference between the levels of CEA, CA125, CA199, NSE in lung cancer with bone metastases and without bone metastases (P < 0.05). The sensitivity of "9"9"mTc-MDP whole-body bone scanning in diagnosis of lung cancer with bone metastasis was 84.91%. Conclusion: The average value of CEA, CA125, and CA199, SCC, NSE and CA15-3 in lung cancer patients were significantly higher than the control group. In addition, there is a significantly correlation between the occurrence

    Full Text Available Barrie Rathbone,1 Janusz Jankowski,2 Michael Rathbone31University Hospitals of Leicester, Leicester, 2Sir James Black Professor Queen Mary University of London, 3St George's University of London, London, United KingdomAbstract: Esophageal cancer is the sixth commonest cause of cancer death worldwide. It predominantly occurs in two histological types, ie, squamous cell carcinoma and adenocarcinoma, each with its own distinct geographical distribution and natural history. The incidence of esophageal adenocarcinoma is rising, as is that of its precursor lesion, Barrett's esophagus, which consists of metaplastic change in the squamous mucosa of the esophagus in response to damage by gastroesophageal reflux disease. The principal risk factors for esophageal cancer are cigarette smoking and alcohol consumption, reflux disease, and obesity. In tumors without local invasion or distant metastases, surgery remains the treatment option of choice, although there are considerable differences of opinion regarding the roles of chemotherapy and radiotherapy. A wide variety of endoscopic treatments are available for dysplastic lesions and palliation. Despite the availability of increasingly complex imaging modalities and expensive and possibly ineffective attempts at screening, the evidence base is conflicted and the prognosis remains poor. However, from a recent large systematic review, three clear recommendations can be made, ie, use of endoscopic resection for high grade dysplasia, use of radiofrequency ablation for residual premalignant lesions, and, finally, prevention of risk factors for cancer, such as smoking, alcohol consumption, and obesity.Keywords: cancer, Barrett's, esophagus, squamous cell carcinoma, adenocarcinoma

  14. Hyperthermia, immunity and metastases

    International Nuclear Information System (INIS)

    Lopatin, V.F.

    1983-01-01

    The analysis of literature data concerning local hyperthermia effects shows that temperatures over 41-42 deg C (in the whole tumor volume), causing tumor growth inhibition and cell injury, can change antigenic nature of a malignant tissue. The tumor injured by thermal effect is able probably the full length of time of injured tissue resorption to maintain at a sufficiently high level antitumoral immunity and lay obstacles to emergence of metastases or even cause regression of those tumoral foci which have not been exposed to direct effect of the injuring agent. The facts of tumoral foci regression take place also upon radiation effect which is associated as well with participation of immune mechanisms. In.experiments with animals an essential increase of immunogenic character of malignant cells exposed to ionizing radiation effect has been observed. It follows that radiation injury of tumoral tissue as well as thermal one is able to stimulate antitumoral immunity and reduce the probability of emergence of metastases. But in case of radiotherapy immunosuppression effect of ionizing radiation (at the expense of inhibition of proliferation and death of immunocompetent cells) can essentially overlap immunostimulating effect related to the changes in antigenic character of tumoral cells

    Lee, Doo-Ho; Ahn, Young Joon; Shin, Rumi; Lee, Hae Won

    2015-08-01

    The patient was a 70-year-old male whose chief complaints were obstructive jaundice and weight loss. Abdominal imaging studies showed a 2.5 cm sized mass at the distal common bile duct, which was suggestive of bile duct cancer. Eccentric enhancing wall thickening in the transverse colon was also shown, suggesting concomitant colon cancer. A colonoscopy revealed a lumen-encircling ulcerofungating mass in the transverse colon, that was pathologically proven to be adenocarcinoma. The bile duct pathology was also adenocarcinoma. Pylorus-preserving pancreaticoduodenectomy and extended right hemicolectomy were performed under the diagnosis of double primary cancers. Postoperative histopathologic examination revealed moderately differentiated mucinous adenocarcinoma of transverse colon cancer, and mucinous adenocarcinoma of the distal common bile duct. Immunohistochemical staining studies showed that the bile duct cancer had metastasized from the colon cancer. The patient recovered uneventfully from surgery and will be undergoing chemotherapy for three months.

    Purpose: Extracranial metastases of malignant gliomas are rare. We report 2 cases with spinal metastases in patients suffering from glioma. Patients and Method: Two patients (33 and 57 years old) developed spinal canal metastases of a glioblastoma multiforme and anaplastic astrocytoma Grade III respectively 25 and 9 months after surgical resection and radiotherapy. Both metastases were confirmed pathohistologically. Results: Intraspinal metastases were irradiated with a total dose of 12.6 Gy and 50 Gy. Treatment withdrawal was necessary in one patient due to reduced clinical condition. Regression of neurological symptoms was observed in the second patient. Conclusions: Spinal spread of malignant glioma should be considered during care and follow-up in glioma patients with spinal symptoms. (orig.) [de

    The Follicle Stimulating Hormone receptor (FSHR) is expressed by the vascular endothelium in a wide range of human tumors. It was not determined however if FSHR is present in metastases which are responsible for the terminal illness. We used immunohistochemistry based on a highly FSHR-specific monoclonal antibody to detect FSHR in cancer metastases from 6 major tumor types (lung, breast, prostate, colon, kidney, and leiomyosarcoma) to 6 frequent locations (bone, liver, lymph node, brain, lung, and pleura) of 209 patients. In 166 patients examined (79%), FSHR was expressed by blood vessels associated with metastatic tissue. FSHR-positive vessels were present in the interior of the tumors and some few millimeters outside, in the normally appearing tissue. In the interior of the metastases, the density of the FSHR-positive vessels was constant up to 7 mm, the maximum depth available in the analyzed sections. No significant differences were noticed between the density of FSHR-positive vessels inside vs. outside tumors for metastases from lung, breast, colon, and kidney cancers. In contrast, for prostate cancer metastases, the density of FSHR-positive vessels was about 3-fold higher at the exterior of the tumor compared to the interior. Among brain metastases, the density of FSHR-positive vessels was highest in lung and kidney cancer, and lowest in prostate and colon cancer. In metastases of breast cancer to the lung pleura, the percentage of blood vessels expressing FSHR was positively correlated with the progesterone receptor level, but not with either HER-2 or estrogen receptors. In normal tissues corresponding to the host organs for the analyzed metastases, obtained from patients not known to have cancer, FSHR staining was absent, with the exception of approx. 1% of the vessels in non tumoral temporal lobe epilepsy samples. FSHR is expressed by the endothelium of blood vessels in the majority of metastatic tumors

  19. Management of unresectable, locally advanced pancreatic adenocarcinoma.

    2018-02-01

    The diagnosis of unresectable locally advanced pancreatic adenocarcinoma (LAPC) requires confirmation, through imaging tests, of the unfeasibility of achieving a complete surgical resection, in the absence of metastatic spread. The increase in overall survival (OS), together with an appropriate symptom management is the therapeutic target in LAPC, maintaining an acceptable quality of life and, if possible, increasing the time until the appearance of metastasis. Chemoradiation (CRT) improves OS compared to best support treatment or radiotherapy (RT) but with greater toxicity. No significant increase in OS has been achieved with CRT when compared to chemotherapy (QT) alone in patients without disease progression after four months of treatment with QT. However, a significantly better local control, that is, a significant increase in the time to disease progression was associated with this approach. The greater effectiveness of the schemes FOLFIRINOX and gemcitabine (Gem) + Nab-paclitaxel compared to gemcitabine alone, has been extrapolated from metastatic disease to LAPC, representing a possible alternative for patients with good performance status (ECOG 0-1). In the absence of randomized clinical trials, Gem is the standard treatment in LAPC. If disease control is achieved after 4-6 cycles of QT, the use of CRT for consolidation can be considered an option vs QT treatment maintenance. Capecitabine has a better toxicity profile and effectiveness compared to gemcitabine as a radiosensitizer. After local progression, and without evidence of metastases, treatment with RT or CRT, in selected patients, can support to maintain the regional disease control.

    2017-01-01

    The majority of lung cancer deaths are caused by metastatic disease. MicroRNAs (miRNAs) are posttranscriptional regulators of gene expression and miRNA dysregulation can contribute to metastatic progression. Here, small RNA sequencing was used to profile the miRNA and piwi-interacting RNA (piRNA......) transcriptomes in relation to lung cancer metastasis. RNA-seq was performed using RNA extracted from formalin-fixed paraffin embedded (FFPE) lung adenocarcinomas (LAC) and brain metastases from 8 patients, and LACs from 8 patients without detectable metastatic disease. Impact on miRNA and piRNA transcriptomes...... was subtle with 9 miRNAs and 8 piRNAs demonstrating differential expression between metastasizing and non-metastasizing LACs. For piRNAs, decreased expression of piR-57125 was the most significantly associated with distant metastasis. Validation by RT-qPCR in a LAC cohort comprising 52 patients confirmed...

    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.

    Objective: Pancreatic solid pseudopapillary tumor (SPT) is a rare benign tumor. Little data are available on positron emission tomographic/computed tomographic (PET/CT) characteristics of this tumor. Therefore, we analyzed the metabolic characteristics of SPT using F-18-FDG PET/CT and compared the results with those of pancreatic ductal adenocarcinoma. Methods: We retrospectively reviewed the records of 11 SPT patients and 46 patients with ductal adenocarcinoma. Ten SPT patients had primary tumors and 1 patient had metastatic SPT. Maximum standardized uptake value (max SUV), mean SUV, metabolic tumor volume (MTV), total lesion glycolysis (TLG), and tumor-to-background ratio (TBR) were evaluated. Mann–Whitney U test between pancreatic SPT and ductal adenocarcinoma was performed. In addition, age, gender and tumor size-adjusted analysis of covariance (ANCOVA) was done between pancreatic SPT and ductal adenocarcinoma. Results: Compared with pancreatic ductal adenocarcinomas, SPTs had significantly higher tumor size-adjusted MTV and TLG. MTV and TLG values were significantly correlated with T-stage of the SPTs. In 1 SPT patient, metastases in the liver and mesentery were revealed by intense uptake of FDG on F-18-FDG PET/CT, and after PET/CT had suggested the presence of pancreatic SPT. Conclusion: We recommend that SPT be considered when a solid pancreatic mass with increased FDG metabolism is encountered on PET/CT. F-18-FDG PET/CT may be useful in detecting subtle metastases of SPT

    Full Text Available Metastasis to the brain is a feared complication of systemic cancer, associated with significant morbidity and poor prognosis. A better understanding of the tumor metabolism might help us meet the challenges in controlling brain metastases. The study aims to characterize the metabolic profile of brain metastases of different origin using high resolution magic angle spinning (HR-MAS magnetic resonance spectroscopy (MRS to correlate the metabolic profiles to clinical and pathological information. Biopsy samples of human brain metastases (n = 49 were investigated. A significant correlation between lipid signals and necrosis in brain metastases was observed (p < 0.01, irrespective of their primary origin. The principal component analysis (PCA showed that brain metastases from malignant melanomas cluster together, while lung carcinomas were metabolically heterogeneous and overlap with other subtypes. Metastatic melanomas have higher amounts of glycerophosphocholine than other brain metastases. A significant correlation between microscopically visible lipid droplets estimated by Nile Red staining and MR visible lipid signals was observed in metastatic lung carcinomas (p = 0.01, indicating that the proton MR visible lipid signals arise from cytoplasmic lipid droplets. MRS-based metabolomic profiling is a useful tool for exploring the metabolic profiles of metastatic brain tumors.

  7. Criteria for palliation of bone metastases - Clinical applications

    International Nuclear Information System (INIS)

    2008-02-01

    Bone metastases are a frequent complication of cancer. It is estimated that they arise in 14-70% of all tumour patients, while it was reported that they occur in 70-85% patients in autopsy material. Although they may arise from any primary malignant tumour, certain tumours such as breast, prostate, lung, thyroid, kidney and myeloma have a predilection for a spread to bone. Bone metastases frequently cause pain, but there are also clinical situations with bone metastases causing no pain at all. The overall importance of the problem of bone metastases is well recognized by the fact that each year hundreds of thousands of cancer patients develop bone metastases. For example, more than 100 000 new patients develop this condition in the United States of America, although the prevalence is estimated to be double the number of new cases. While it is virtually unknown how many cancer patients in the developing countries develop bone metastases, it is not unrealistic to expect that these figures largely surpass those coming from the developed countries. The reason is simply that more patients in the developing countries are diagnosed as having locally advanced or metastatic cancer that will eventually widely disseminate, including bone metastasis as well. Furthermore, at least some of the cancer patients may survive prolonged periods of time. They can also develop earlier and more severe symptoms than patients harbouring other types (locations) of metastases, emphasizing the importance of the overall problem of painful bone metastases. In addition, there is a big socioeconomic problem of bone metastasis, burdening health care systems worldwide, while having continuous adverse psychological effect on both patients and their families. The management of patients with metastatic bone pain must be a multidisciplinary approach and includes the use of analgesia, radiotherapy, surgery, chemotherapy, hormone treatment, radioisotopes and bisphosphonates.

    Recently, the space occupying lesions in the liver were well established and recognized by radioisotope color scan. In addition, the lesions were easily localized in the supine and the right lateral projections. The findings of hepatoma, abscess and cyst were seen as filling defects which were similar to the findings of the hepatic metastases. In this study, we analysis of 70 cases of the hepatic metastases, 80 cases of the hepatoma and 100 cases of the liver abscess which were obtained by radiogold color scan and confirmed by a needle biopsy or laparotomy. Summary of analysis as follows: 1. Primary site in 70 cases of hepatic metastases. Stomach 30 cases (42.8%) Biliary Tract 10 cases (12.3%) Colon 8 cases (11.4%) Lung 6 cases (8.5%) Ovary 6 cases (8.5%) Pancreas 3 case (4.3%) Thyroid 2 cases (3.5%) Breast 2 cases (3.5%) Kidney, Cervix, Esophagus 1 case. 2. Hepatomegaly were seen in 22 cases (32%) of the hepatic metastases and relatively small in percentage compare with the hepatoma and abscess. 3. Single space occupying lesion were demonstrated in 26 cases (35.7%) of the hepatic metastases, 55 cases (70.2%) of the hepatoma and 72 cases (72%) of the abscess. Two space occupying lesion were in the scan in 10 cases (12.3%) of the hepatic metastases, 8 cases (9.5%) of the hepatoma and 10 cases (10%) of the abscess. Multiple space occupying lesions were scan in 15 cases (21.4%) of the hepatic metastases, 14 cases (17.5%) of the hepatoma and 13 cases (13%) of the abscess. Compare with the hepatoma and abscess, the hepatic metastases tend to more than one space occupying lesions. 4. The appearance and location of the metastatic lesions showed somewhat significant. In 26 of 30 cases (81.6%) of the stomach carcinoma revealed the lesions mostly located in the porta hepatis and right lower lobe of the liver. Multiple and discrete metastatic lesions were usually from the colon carcinoma.

    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

    Full Text Available Cancer of the fallopian tube accounts for <0.1% of all gynaecologic cancers. Primary adenocarcinoma of the fallopian tube is usually unilateral , extremely rare that clinically and histologically resembles epithelial ovarian cancer(EOC.It is more common for cancer to spread or metastasize from ovaries or endometrium, than for cancer to actually originate in the fallopian tubes. Some of the common symptoms are abnormal vaginal bleeding, abdominal pain, abnormal vaginal discharge and pelvic mass which are present in up to two-thirds of patients and may mimic those of other gynecological problems. So we are presenting a rare case of stage IB primary fallopian tube cancer which is difficult to diagnose early.

    Small focal ischaemic brain lesions are said to be easy to identify in the acute stage and to differentiate from older lesions using diffusion-weighted imaging (DWI). Brain metastases are common and the aim of this study was to evaluate the risk of misinterpretation as ischaemic lesions in a standard MRI protocol for clinical stroke. Of 26 patients investigated with MRI for possible metastases, 12 did have metastatic brain lesions, including most of the common tumours. On a 1.5 tesla imager, we obtained DWI, plus T2- and T1-weighted images, the latter before and after triple-dose contrast medium. Well-circumscribed brain lesions with a decreased apparent diffusion coefficient and a slightly or moderately increased signal on T2-weighted images were found in patients with metastases from a small-cell bronchial carcinoma and a pulmonary adenocarcinoma. The same features were also found in metastases from a breast carcinoma but the lesions were surrounded by oedema. With a standard DWI protocol, the features of common brain metastases may overlap with those of small acute and subacute ischaemic lesions. (orig.)

    Full Text Available Abstract Background Microarray technology has allowed to molecularly characterize many different cancer sites. This technology has the potential to individualize therapy and to discover new drug targets. However, due to technological differences and issues in standardized sample collection no study has evaluated the molecular profile of epithelial human cancer in a large number of samples and tissues. Additionally, it has not yet been extensively investigated whether metastases resemble their tissue of origin or tissue of destination. Methods We studied the expression profiles of a series of 1566 primary and 178 metastases by unsupervised hierarchical clustering. The clustering profile was subsequently investigated and correlated with clinico-pathological data. Statistical enrichment of clinico-pathological annotations of groups of samples was investigated using Fisher exact test. Gene set enrichment analysis (GSEA and DAVID functional enrichment analysis were used to investigate the molecular pathways. Kaplan-Meier survival analysis and log-rank tests were used to investigate prognostic significance of gene signatures. Results Large clusters corresponding to breast, gastrointestinal, ovarian and kidney primary tissues emerged from the data. Chromophobe renal cell carcinoma clustered together with follicular differentiated thyroid carcinoma, which supports recent morphological descriptions of thyroid follicular carcinoma-like tumors in the kidney and suggests that they represent a subtype of chromophobe carcinoma. We also found an expression signature identifying primary tumors of squamous cell histology in multiple tissues. Next, a subset of ovarian tumors enriched with endometrioid histology clustered together with endometrium tumors, confirming that they share their etiopathogenesis, which strongly differs from serous ovarian tumors. In addition, the clustering of colon and breast tumors correlated with clinico-pathological characteristics

    The expression of the adenosine deaminase complexing protein (ADCP) was investigated by immunohistochemistry in the normal and hyperplastic human prostate, in 30 prostatic adenocarcinomas, and in seven human prostatic adenocarcinoma cell lines grown as xenografts in athymic nude mice. In the normal and hyperplastic prostate, ADCP was localized exclusively in the apical membrane and the apical cytoplasm of the glandular epithelial cells. In prostatic adenocarcinomas, four distinct ADCP expression patterns were observed: diffuse cytoplasmic, membranous, both cytoplasmic and membranous, and no ADCP expression. The expression patterns were compared with the presence of metastases. We found an inverse correlation between membranous ADCP immunoreactivity and metastatic propensity. Exclusively membranous ADCP immunoreactivity occurred only in non-metastatic tumours. In contrast, the metastatic tumours showed no or diffuse cytoplasmic ADCP immunoreactivity. This suggests that immunohistochemical detection of ADCP might predict the biological behaviour of prostatic cancer. However, the occurrence of membranous ADCP immunoreactivity in the xenograft of a cell line (PC-EW), derived from a prostatic carcinoma metastasis, indicates that not only the tendency to metastasize modulates ADCP expression.

    Cisplatin, a commonly used cancer chemotherapeutic, has a dose-limiting side effect of nephrotoxicity. Approximately 30% of patients administered cisplatin suffer from kidney injury, and there are limited treatment options for the treatment of cisplatin-induced kidney injury. Suramin, which is Federal Drug Administration-approved for the treatment of trypanosomiasis, improves kidney function after various forms of kidney injury in rodent models. We hypothesized that suramin would attenuate cisplatin-induced kidney injury. Suramin treatment before cisplatin administration reduced cisplatin-induced decreases in kidney function and injury. Furthermore, suramin attenuated cisplatin-induced expression of inflammatory cytokines and chemokines, endoplasmic reticulum stress, and apoptosis in the kidney cortex. Treatment of mice with suramin 24 h after cisplatin also improved kidney function, suggesting that the mechanism of protection is not by inhibition of tubular cisplatin uptake or its metabolism to nephrotoxic species. If suramin is to be used in the context of cancer, then it cannot prevent cisplatin-induced cytotoxicity of cancer cells. Suramin did not alter the dose-response curve of cisplatin in lung adenocarcinoma cells in vitro. In addition, suramin pretreatment of mice harboring lung adenocarcinomas did not alter the initial cytotoxic effects of cisplatin (DNA damage and apoptosis) on tumor cells. These results provide evidence that suramin has potential as a renoprotective agent for the treatment/prevention of cisplatin-induced acute kidney injury and justify future long-term preclinical studies using cotreatment of suramin and cisplatin in mouse models of cancer.

    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.

    Complications of bone metastases can seriously influence quality of life of the patients including of their independence in activities of daily living. Bisfosfonates are reducing skeletal morbidity in solid tumors and in multiple myeloma by 30 - 50% (1). They are not only used in active antineoplastic therapy in the prevention of skeletal complications by bone metastases but they are also significantly useful in prevention of the decrease of osseous mass by hormonal manipulation. Preclinical and in part clinical data suppose that there is some role of bisfosfonates in prevention of formation of metastases by early cancer. Denosumab is fully humanized antibody against RANKL (receptor activator of nuclear factor κ-B ligand) which is very important in pathogenesis of bone resorption induced by osteoclasts. In this work we discuss about pathological mechanisms of bone resorption in multiple myeloma and solid tumors, we resume data from randomized clinical trials and we focus on the application of anti resorption therapy in clinical practice.

    Experiences are reported obtained with radiation therapy of brain metastases in 121 patients during the last 15 years. The treatment to a lesser extent aimed at prolongation of survival but much more at the attempt to alleviate troubles and to spare pain. The indication thus involved medical points of view as well as ethical ones. The radiotherapy of cerebral metastases comprises the whole cranial volume and requires a focal dose of minimally 4,000 R within four weeks. In 53% of the patients, the regression of neurological symptoms was considerable, in 18% even complete, partly beginning already after a few days of treatment. The number of recurrences was small. Under conditions of rigorous indication, the radiation therapy of brain metastases offers a rewarding palliative measure.

    To retrospectively investigate clinical outcome and differential CT features of gallbladder (GB) neuroendocrine tumours (NETs) from adenocarcinomas (ADCs). Nineteen patients with poorly-differentiated (PD) NETs and 19 patients with PD ADCs were enrolled. Clinical outcome was compared by the Kaplan-Meier method. We assessed qualitative and quantitative CT features to identify significant differential CT features of PD NETs from ADCs using univariate and multivariate analyses. Receiver operating characteristic (ROC) analysis was used for quantitative CT features. PD NETs showed poorer prognosis with significantly shorter median survival days than ADCs (363 vs. 590 days, P = 0.03). On univariate analysis, NETs more frequently manifested as GB-replacing type and showed well-defined margins accompanied with intact overlying mucosa. On multivariate analysis, well-defined margin was the sole significant CT differentiator (odds ratio = 27.817, P = 0.045). Maximum size of hepatic and lymph node (LN) metastases was significantly larger in NETs (11.0 cm and 4.62 cm) than ADCs (2.40 cm and 2.41 cm). Areas under ROC curves for tumour-to-mucosa ratio, maximum size of hepatic and LN metastasis were 0.772, 0.932 and 0.919, respectively (P < 0.05). GB PD NETs show poorer prognosis than ADCs. Well-defined margin, larger hepatic and LN metastases are useful CT differentiators of GB NETs from ADCs. (orig.)

    Medulloblastoma is a relatively common intracranial neoplasm in childhood. Its extraneural spread was, until recently, thought to be a rare occurrence. Metastases are most commonly to bone. Five patients with medulloblastoma metastatic to bone are presented, and findings are compared to those of previous reports. Two of the five cases showed patchy extensive osteosclerosis of the pelvis and/or proximal femora. One case had concurrent lymph node involvement. In patients with past or present medulloblastoma and bone pain, metastases to bone should be excluded. Medulloblastoma metastatic to bone is a rare cause of extensive osteosclerosis. (orig.)

    Brain metastases are the most common intracranial tumors and their incidence is increasing. Untreated brain metastases have a very poor prognosis with a median survival of 1-2 months. Despite the use of surgery and radiotherapy including whole-brain radiation and stereotactic radiosurgery to locally control brain metastases, survival times for those patients has not improved. Although chemotherapy plays a limited role in the treatment of brain metastases, metastases from lung or breast cancer are often well-controlled by chemotherapy. Accumulating evidence suggest that brain metastases are equally sensitive to chemotherapy as are metastases elsewhere in the body in particular chemotherapy-naive cases. Finally, since nearly a half of patients with brain metastases die from progression of systemic disease, control of systemic disease as well as intracranial disease are both important. (author)

    Full Text Available Lung cancer is mostly common occurring oncological disease in the developed countries. Currently lung cancers are subdivided into nonsmall-cell (adenocarcinoma, large-cell, squamous cell and small-cell. The difference in the clinical and morphological picture leads to the necessity of choosing therapeutic approaches to patients of various groups.Lung cancer should be referred to encephalotropic diseases since metastatic lesion of the central nervous system is sufficiently common complication. Successes of complex treatment of primary tumor result in increase of total longlivety currently ther is ageing of patients suffering lung cancer. These factors increase the risk of metastatic lesions of the brain.Interest to the problem of neurosurgical treatment of patients suffering lung cancer is determined by frequency of lesion, varicosity of morphological variants of the disease, requiring various algorithms of treatment and diagnosis.The main role of neurosurgical intervention in cerebral metastases of lung cancer consist in creation of the paled of carrying out combined therapy. Ideally, a neurosurgical operation should be carried out with clearcut observance of oncological principles of ablasty.Adequate comprehensive approach to treatment or patients with cerebral metastases of various forms of lung cancer with the developed of optimal tactics of and stages of treatment would make it possible to increase duration and quality of life of patients.

    The aim of the present study is to identify the incidence and prognostic significance of lymph node metastases near the celiac trunk in patients who underwent neoadjuvant chemo(radio)therapy followed by esophagectomy. Between March 1994 and September 2013 a total of 462 consecutive patients with cancer of the esophagus or gastroesophageal junction (GEJ) who underwent potentially curative esophageal resection after neoadjuvant chemotherapy (N=88; 19.0%) or neoadjuvant chemoradiotherapy (CRT) (N=374; 81.0%) were included. Seventy one (15.4%) patients had truncal node metastases in the resection specimen. Metastases to these nodes occurred more frequently in male patients with adenocarcinoma and in tumors at the gastro-esophageal junction. A lower response to neoadjuvant treatment, higher ypT and ypN stages and a poorer grade of differentiation were significantly related with truncal node metastases. Patients with tumor positive truncal nodes had a worse median overall survival (17 vs. 55 months). In multivariate analysis, truncal node metastases were independently associated with a worse survival. Only 22 (31.0%) of the 71 patients with tumor positive truncal nodes were identified preoperatively with EUS or CT. In contrast, 37 patients had suspicious truncal nodes on EUS or CT, but metastases in the pathology specimen were absent. In the present study, it is demonstrated that positive truncal nodes in the resection specimen after neoadjuvant therapy, are associated with advanced tumor stages and are an independent factor for inferior survival.

    Full Text Available Abstract Colorectal cancer (CRC is the third most common cancer in the word. Liver metastasis is the most common site of colorectal metastases. The prognosis of resectable colorectal liver metastases (CRLM was improved in the recent years with the consideration of chemotherapy and surgical resection as part of the multidisciplinary management of the disease; the current 5-year survival rates after resection of liver metastases are 25% to 40%. Resectable synchronous or metachronous liver metastases should be treated with perioperative chemotherapy based on three months of FOLFOX4 (5-fluorouracil [5FU], folinic acid [LV], and oxaliplatin chemotherapy before surgery and three months after surgery. In the case of primary surgery, pseudo-adjuvant chemotherapy for 6 months, based on 5FU/LV, FOLFOX4, XELOX (capecitabine and oxaliplatin or FOLFIRI (5FU/LV and irinotecan, should be indicated. In potentially resectable disease, primary chemotherapy based on more intensive regimens such as FOLFIRINOX (5FU/LV, irinotecan and oxaliplatin should be considered to enhance the chance of cure. The palliative chemotherapy based on FOLFIRI, or FOLFOX4/XELOX with or without targeted therapies, is the mainstay treatment of unresectable disease. This review would provide additional insight into the problem of optimal integration of chemotherapy and surgery in the management of CRLM.

    2017-11-01

    Gastric mixed adenoneuroendocrine carcinoma(MANEC)with multiple liver metastases is a rare condition with most data being derived from case reports. We present a case with liver metastases from gastric MANEC that respond remarkably to chemotherapy. Sixty-one-year-old male with severe anemia referred to surgical consultation due to advanced gastric cancer with multiple liver metastases. To relieve uncontrollable tumor bleeding, simple distal gastrectomy for symptom palliation was performed. Based on the tentative diagnosis with gastric poorly differentiated adenocarcinoma, a course of TS-1 and oxaliplatin therapy was administrated. Thereafter final diagnosis with neuroendocrine carcinoma with tubular adenocarcinoma was made, and the chemotherapy was switched to etoposide and cisplatin. Follow up abdominal CT scan after the third course of the therapy showed remarkable tumor shrinkages(PR). In anticipation of the chemotherapy effects in the adjuvant setting, we performed liver metastasectomy for curative intent. Two of 6 resected liver specimens showed no viable cancer cells at all (pCR). However, immediately after the surgery, multiple liver metastases developed, and the recurrent masses had kept growing up rapidly. The third line carboplatin and etoposide chemotherapy was given once but was withdrawn because of bone marrow suppression. At the present, the patient is alive with recurrent diseases for 18 months after initial diagnosis.

  18. Retroperitoneal and lateral pelvic lymphadenectomy mapped by lymphoscintigraphy for rectal adenocarcinoma staging

    2010-01-01

    The good prognosis of retroperitoneal and lateral pelvic lymphadenectomy has raised the question of whether total mesorectal excision is suitable for adequate staging of rectal adenocarcinoma patients. The aims of this study were to determine the accuracy of dye and probe detection of metastatic retroperitoneal and/or lateral pelvic nodes and to define the upstaging impact of retroperitoneal and lateral pelvic lymphadenectomy in rectal adenocarcinoma patients. Ninety-seven rectal adenocarcinoma patients were submitted to total mesorectal excision and retroperitoneal and lateral pelvic lymphadenectomy. Lymphoscintigraphy using technetium-99 m-phytate and patent blue was performed to detect blue and/or radioactive retroperitoneal and/or lateral pelvic nodes which were examined histopathologically and immunohistochemically with a step-sectioning technique. Mesorectal mean node count was 11.5 and retroperitoneal and/or lateral pelvic node was 11.7. Retroperitoneal and lateral pelvic lymphadenectomy identified metastases in 17.5%, upstaging 8.2%. Variables related to metastatic retroperitoneal and/or lateral pelvic nodes were the following: Stage III in total mesorectal excision specimens (P<0.04), pT3/pT4 tumors (P=0.047), high levels of carcinoembryonic antigen (P=0.014) and large tumors (P=0.03). Marker migration to retroperitoneal and/or lateral pelvic nodes occurred in 37.1%, upstaging 11.1%. The markers' accuracy in the detection of metastatic retroperitoneal and/or lateral pelvic nodes was 100%. Retroperitoneal and lateral pelvic lymphadenectomy detected an important rate of metastatic retroperitoneal and/or lateral pelvic nodes (RLPN), resulting in upstaging. When markers migrated, they were able to detect RLPN metastases. The use of markers should be improved in the identification of RLPN metastases for selective indication of retroperitoneal and lateral pelvic lymphadenectomy. (author)

  19. Coexistence of Gastric Adenocarcinoma and Choriocarcinoma: Complete Response to Trastuzumab and Chemotherapy

    Directory of Open Access Journals (Sweden)

    Seyda Gunduz

    2012-07-01

    Full Text Available Gastric choriocarcinoma is a rare neoplasm and usually accompanies gastric adenocarcinoma. The prognosis is poor due to the aggressive course of the disease. A 57-year-old female patient with weight loss and abdominal pain was examined. The patient was operated following the examination, and pathological analysis revealed the presence of a gastric adenocarcinoma associated with choriocarcinoma. Immunohistochemical analysis showed a positive reaction with antibodies to beta-human chorionic gonadotropin and overexpression of the cErbB2 proto-oncogene. Staging revealed multiple metastases in the liver. A complete response was obtained with a combination of trastuzumab and chemotherapy. The diagnosis of gastric choriocarcinomas without pathological examination is difficult due to their rare occurrence. A complete response can be obtained with trastuzumab in the treatment of cases with overexpression of the cErbB2 protein.

    1997-01-01

    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

  1. Radiological diagnosis of skeletal metastases

    International Nuclear Information System (INIS)

    Soederlund, V.

    1996-01-01

    The clinical management of patients with skeletal metastases puts new demands on imaging. The radiological imaging in screening for skeletal metastases entails detection, metastatic site description and radiologically guided biopsy for morphological typing and diagnosis. Regarding sensitivity and the ease in performing surveys of the whole skeleton, radionuclide bone scintigraphy still is the first choice in routine follow-up of asymptomatic patients with metastatic disease of the skeleton. A negative scan has to be re-evaluated with other findings, with emphasis on the possibility of a false-negative result. Screening for metastases in patients with local symptoms or pain is best accomplished by a combination of radiography and MRI. Water-weighted sequences are superior in sensitivity and in detection of metastases. Standard spin-echo sequences on the other hand are superior in metastatic site description and in detection of intraspinal metastases. MRI is helpful in differentiating between malignant disease, infection, benign vertebral collapse, insufficiency fracture after radiation therapy, degenerative vertebral disease and benign skeletal lesions. About 30% of patients with known cancer have benign causes of radiographic abnormalities. Most of these are related to degenerative diseases and are often easily diagnosed. However, due to overlap in MRI characteristics, bone biopsy sometimes is essential for differentiating between malignant and nonmalignant lesions. Performing bone biopsy and aspiration cytology by radiologist and cytologist in co-operation has proven highly accurate in diagnosing bone lesions. The procedure involves low risk to the patient and provides a morphological diagnosis. Once a suspected metastatic lesion is detected, irrespective of modality, the morphological diagnosis determines the appropriate work-up imaging with respect to the therapy alternatives. (orig./VHE)

    26 patients with pulmonary metastases of renal adenocarcinomas were examined under the aspect of tumor biology. Growth functions were used to calculate the time at which the metastases began to grow, in relation to the time of operation and with the aim to get information on the indication for preoperative radiotherapy. In 3 patients (11.5%) there was an indication for preoperative irradiation. For comparative clinical tests as to the value of preoperative irradiation a minimum of 871 patients are needed in each group for comparison to evaluate the 3-year survival rate and 489 patients to evaluate the 5-year survival rate in order to be certain of the positive effect of preoperative irradiation with 1% statistical probability. The investigations are to be considered a model.

    A 61-year-old black man presented with metastases to the right groin 5 years after 125iodine treatment for a well differentiated primary prostatic adenocarcinoma. Medium sized veins within and immediately adjacent to the neoplasm showed marked mural thickening due to hypertrophy and hyperplasia of the inner circular and outer longitudinal muscles. There was no histological evidence of radiation effect in the stroma or in the tumor cells. We could find no report in the literature of such changes associated with metastatic carcinoma

    Full Text Available Hepatoid adenocarcinoma of the urachus is a rare condition. We present the case of a 51-year-old female who developed abdominal pain and hematuria. Pelvic magnetic resonance imaging (MRI reported an urachal mass with invasion to the bladder that was resected by partial cystectomy. On light microscopy the tumor resembled liver architecture, with polygonal atypical cells in nest formation and trabecular structures. Immunochemistry was positive for alfa-fetoprotein (AFP and serum AFP was elevated. Hepatoid adenocarcinomas have been reported in multiple organs, being most commonly found in the stomach and the ovaries. Bladder compromise has been rarely described in the literature, and it has been associated with poor prognosis, low remission rates, and early metastasis.

    Intracranial metastatic lesions arise through a number of routes. Therefore, they can involve any part of the central nervous system and their imaging appearances vary. Magnetic resonance imaging (MRI) plays a key role in lesion detection, lesion delineation, and differentiation of metastases from other intracranial disease processes. This article is a reasoned pictorial review illustrating the many faces of intracranial metastatic lesions based on the location - intra-axial metastases, calvarial metastases, dural metastases, leptomeningeal metastases, secondary invasion of the meninges by metastatic disease involving the calvarium and skull base, direct or perineural intracranial extension of head and neck neoplasm, and other unusual manifestations of intracranial metastases. We also review the role of advanced MRI to distinguish metastases from high-grade gliomas, tumor-mimicking lesions such as brain abscesses, and delayed post-radiation changes in radiosurgically treated patients.

    Tumors that formed in newborn nude mice that were inoculated with 10(7) Madin-Darby canine kidney (MDCK) cells were associated with a failure-to-thrive (FTT) syndrome consisting of growth retardation, lethargy, weakness, and dehydration. Scoliosis developed in 41% of affected pups. Pups were symptomatic by week 2; severely affected pups became moribund and required euthanasia within 3 to 4 wk. Mice with FTT were classified into categories of mild, moderate, and severe disease by comparing their weight with that of age-matched normal nude mice. The MDCK-induced tumors were adenocarcinomas that invaded adjacent muscle, connective tissue, and bone; 6 of the 26 pups examined had lung metastases. The induction of FTT did not correlate with cell-line aggressiveness as estimated by histopathology or the efficiency of tumor formation (tumor-forming dose 50% endpoint range = 10(2.8) to 10(7.5)); however, tumor invasion of the paravertebral muscles likely contributed to the scoliosis noted. In contrast to the effect of MDCK cells, tumor formation observed in newborn mice inoculated with highly tumorigenic, human-tumor-derived cell lines was not associated with FTT development. We suggest that tumor formation and FTT are characteristics of these MDCK cell inocula and that FTT represents a new syndrome that may be similar to the cachexia that develops in humans with cancer or other diseases.

  15. Understanding the Progression of Bone Metastases to Identify Novel Therapeutic Targets

    Directory of Open Access Journals (Sweden)

    Annie Schmid-Alliana

    2018-01-01

    Full Text Available Bone is one of the most preferential target site for cancer metastases, particularly for prostate, breast, kidney, lung and thyroid primary tumours. Indeed, numerous chemical signals and growth factors produced by the bone microenvironment constitute factors promoting cancer cell invasion and aggression. After reviewing the different theories proposed to provide mechanism for metastatic progression, we report on the gene expression profile of bone-seeking cancer cells. We also discuss the cross-talk between the bone microenvironment and invading cells, which impacts on the tumour actions on surrounding bone tissue. Lastly, we detail therapies for bone metastases. Due to poor prognosis for patients, the strategies mainly aim at reducing the impact of skeletal-related events on patients’ quality of life. However, recent advances have led to a better understanding of molecular mechanisms underlying bone metastases progression, and therefore of novel therapeutic targets.

    2017-07-27

    Colloid adenocarcinoma of the lung is a rare subtype of variants of invasive adenocarcinomas. We report the appearance of this unusual entity on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography. A 60-year-old man of Chinese Han nationality coughed with a little white sputum for 1 month. Chest computed tomography showed multiple bilateral subpleural nodules and plaques accompanied by air bronchograms, which were most concentrated in the lower lobe of his right lung. Positron emission tomography indicated increased radioactivity uptake with a maximum standardized uptake value of 3.5. Positron emission tomography/computed tomography showed a soft tissue density lesion in his left adrenal gland with a maximum standardized uptake value of 4.1. The positron emission tomography/computed tomography appearance suggested a primary colloid adenocarcinoma in the lower lobe of his right lung accompanied by intrapulmonary and left adrenal gland metastases. The diagnostic rate of colloid adenocarcinoma can be increased by combining the anatomic and metabolic information of lesions. The advantage of positron emission tomography/computed tomography in the diagnosis of colloid adenocarcinoma, as with other cancers, is the ability to locate extrapulmonary disease, facilitating clinical staging.

    To evaluate the CT findings of small bowel metastases from primary lung cancer. Of the 1468 patients with primary lung cancer between 1990 and 2000, 13 patients who had metastasis to the small intestine were collected. Of these 13 patients, nine who underwent CT scan were included for analysis. The pathologic diagnoses of primary lung cancer in these nine patients were squamous cell carcinoma in six, adenocarcinoma in two, and large cell carcinoma in one. CT scans were analyzed with regard to the site and patterns (intraluminal mass/bowel wall thickening/bowel implants) of metastatic masses, and the presence or absence of complication such as intussusception, obstruction, or perforation of the small bowel. The medical records of the patients were also reviewed retrospectively for evaluation of presenting abdominal symptom and time interval of metastases from initial diagnosis of lung cancer. Metastatic lesions were distributed throughout the small intestine: the duodenum in five, the jejunum in four, the ileum in six, and both jejunum and ileum in one patient. The size of metastatic masses of small bowel ranged from 1.3 cm to 5.0 cm (mean size, 2.6 cm) On CT, the small bowel was involved with intraluminal masses (mean size, 3.4 cm) in eight patients, diffuse wall thickening (mean thickness, 1.6 cm) in five, and bowel implants (mean size, 2.2 cm) in two. Complications occurred in seven patients, including intussusceptions without obstruction in two patients and with obstruction in two, obstruction without intussusceptions in two, and bowel perforation in one. Of 9 patients, 6 had at least one symptom referable to the small bowel including abdominal pain in 4, anemia in 3, vomiting in 1, and jaundice in 1. Lung cancer and small bowel lesions were detected simultaneously in four patients and the time interval of metastases from initial diagnosis of lung cancer ranged from 10 days to 30 months (median interval, 54 days) in patients. CT helps in defining the extent and

Of 9 patients, 6 had at least one symptom referable to the small bowel including abdominal pain in 4, anemia in 3, vomiting in 1, and jaundice in 1. Lung cancer and small bowel lesions were detected simultaneously in four patients and the time interval of metastases from initial diagnosis of lung cancer ranged from 10 days to 30 months (median interval, 54 days) in patients. CT helps in defining the extent and

    Full Text Available Melanomas are malignant neoplasms that originate from melanocytes. The most common are on the skin and mucous membranes. Choroidal melanomas are quite different from cutaneous melanomas with regard to presentation, metastases, and treatment. We report two cases of metastatic gastric malignant melanoma of the eye and skin, with reference to the literature. The first patient was a woman aged 23 years, who underwent gastrectomy 22 months after enucleation of the eye due to malignant choroid melanoma. The second patient was a man, 72 years old, who underwent surgery 28 months before because of malignant melanoma of the skin of the forehead. Paraffin sections, 4 μm thick were stained using a classic method, as well as immunohistochemical DAKO APAAP method, using a specific S - 100 antibody and Melan A antibodies. The stomach is considered a rare place for the development of metastases. Metastases in the stomach are often limited to the submucosal as well as the serousmuscular layer, as noted in one of our patients. Metastatic melanoma of the gastrointestinal tract should be suspected in any patient with a history of malignant melanoma and new gastrointestinal symptoms. Because of the similarity between certain common histopathological types of malignant melanoma, primarily achromatic, and types of primary cancers of the stomach, the following immunohistochemical studies are needed: Melan A and S - 100 protein ( markers of malignant melanoma , as well as mucins: MUC5AC, MUC2 and CDX2 ( markers of different types of primary gastric carcinoma.

    Full Text Available Paraneoplastic neurologic disorders are extremely rare in cancer patients and are most commonly associated with certain tumors, such as ovarian cancer, small cell lung cancer, and breast cancer. We report here a paraneoplastic neurological syndrome in a 53-year-old man with colonic adenocarcinoma with a solitary liver metastasis. His paraneoplastic syndrome was successfully treated by methylprednisolone and primary oncologic therapies including neoadjuvant chemotherapy and definitive surgery. This is also the first documented case of simultaneous manifestation of a sensory neuropathy and limbic encephalitis with colon cancer.

    To evaluate the differential CT features of gastric poorly-differentiated neuroendocrine tumours (PD-NETs) from well-differentiated NETs (WD-NETs) and gastric adenocarcinomas (ADCs) and to suggest differential features of hepatic metastases from gastric NETs and ADCs. Our study population was comprised of 36 patients with gastric NETs (18 WD-NETs, 18 PD-NETs) and 38 patients with gastric ADCs who served as our control group. Multiple CT features were assessed to identify significant differential CT findings of PD-NETs from WD-NETs and ADCs. In addition, CT features of hepatic metastases including the metastasis-to-liver ratio were analyzed to differentiate metastatic NETs from ADCs. The presence of metastatic lymph nodes was the sole differentiator of PD-NETs from WD-NETs (P =.001, odds ratio = 56.67), while the presence of intact overlying mucosa with mucosal tenting was the sole significant CT feature differentiating PD-NETs from ADCs (P =.047, odds ratio = 15.3) For hepatic metastases, metastases from NETs were more hyper-attenuated than those from ADCs. The presence of metastatic LNs and intact overlying mucosa with mucosal tenting are useful CT discriminators of PD-NETs from WD-NETs and ADCs, respectively. In addition, a higher metastasis-to-liver ratio may help differentiate hepatic metastases of gastric NETs from those of gastric ADCs with high accuracy. (orig.)

    Lynch syndrome is an autosomal-dominant disorder caused by defective DNA mismatch repair (MMR) genes and is associated with increased risk of malignancies in multiple organs. Small-intestinal adenocarcinomas are common initial manifestations of Lynch syndrome. To define the incidence and characteristics of Lynch syndrome-related small-intestinal adenocarcinomas, meticulous familial and clinical histories were obtained from 195 patients with small-intestinal adenocarcinoma, and MMR protein immunohistochemistry, microsatellite instability, MLH1 methylation, and germline mutational analyses were performed. Lynch syndrome was confirmed in eight patients (4%), all of whom had synchronous/metachronous malignancies without noticeable familial histories. Small-intestinal adenocarcinomas were the first clinical manifestation in 37% (3/8) of Lynch syndrome patients, and second malignancies developed within 5 years in 63% (5/8). The patients with accompanying Lynch syndrome were younger (≤50 years; P=0.04) and more likely to have mucinous adenocarcinomas (P=0.003), and tended to survive longer (P=0.11) than those with sporadic cases. A meticulous patient history taking, MMR protein immunolabeling, and germline MMR gene mutational analysis are important for the diagnosis of Lynch syndrome-related small-intestinal adenocarcinomas. Identifying Lynch syndrome in patients with small-intestinal adenocarcinoma can be beneficial for the early detection and treatment of additional Lynch syndrome-related cancers, especially in patients who are young or have mucinous adenocarcinomas.

    Purpose: Patients with brainstem metastases have limited treatment options. In this study, we reviewed outcomes after stereotactic radiosurgery (SRS) in the management of patients with brainstem metastases. Methods and Materials: Records were reviewed of 22 consecutive patients presenting with brainstem metastases who underwent SRS. The most frequent primary malignancy was the lung (n = 11), followed by breast (n = 3) and kidney (n = 2). Three patients (14%) also underwent whole-brain radiation therapy (WBRT). The median tumor volume was 0.9 mL (range, 0.1-3.3 mL); the median tumor margin dose was 16 Gy (range, 14-23 Gy). Results: Median survival time after SRS was 8.5 months. Although local tumor control was achieved in all patients with imaging follow-up (n = 19), 5 patients died from development and progression of new brain metastases. Two patients (9%) had symptom improvement after SRS, whereas 1 patient (5%) developed a new hemiparesis after SRS. Conclusions: Radiosurgery is safe and provides a high local tumor control rate for patients with small brainstem metastases. Patients with limited systemic disease and good performance status should be strongly considered for SRS

    Predicting prognosis is the key factor in selecting the proper treatment modality for patients with spinal metastases. Therefore, various assessment systems have been designed in order to provide a basis for deciding the course of treatment. Such systems have been proposed by Tokuhashi, Sioutos, Tomita, Van der Linden, and Bauer. The scores differ greatly in the kind of parameters assessed. The aim of this study was to evaluate the prognostic value of each score. Eight parameters were assessed for 69 patients (37 male, 32 female): location, general condition, number of extraspinal bone metastases, number of spinal metastases, visceral metastases, primary tumour, severity of spinal cord palsy, and pathological fracture. Scores according to Tokuhashi (original and revised), Sioutos, Tomita, Van der Linden, and Bauer were assessed as well as a modified Bauer score without scoring for pathologic fracture. Nineteen patients were still alive as of September 2006 with a minimum follow-up of 12 months. All other patients died after a mean period of 17 months after operation. The mean overall survival period was only 3 months for lung cancer, followed by prostate (7 months), kidney (23 months), breast (35 months), and multiple myeloma (51 months). At univariate survival analysis, primary tumour and visceral metastases were significant parameters, while Karnofsky score was only significant in the group including myeloma patients. In multivariate analysis of all seven parameters assessed, primary tumour and visceral metastases were the only significant parameters. Of all seven scoring systems, the original Bauer score and a Bauer score without scoring for pathologic fracture had the best association with survival (P < 0.001). The data of the present study emphasize that the original Bauer score and a modified Bauer score without scoring for pathologic fracture seem to be practicable and highly predictive preoperative scoring systems for patients with spinal metastases

    The tumor growth-inhibiting and chemo-potentiating effects of vitamin C and K(3)combinations have been demonstrated both in vitro and in vivo. The purpose of this study was to investigate the influence of orally administered vitamin C and K(3) on the metastasis of mouse liver tumor (T.L.T.) cells implanted in C3H mice. Adult male C3H mice were given water containing vitamin C and K3 (15 g/0.15 g dissolved in 1000 ml) beginning 2 weeks before tumor transplantation until the end of the experiment. T.L.T. cells (106) were implanted intramuscularly in the right thigh of mice. All mice were sacrificed 42 days after tumor transplantation. Primary tumor, lungs, lymph nodes and other organs or tissues suspected of harboring metastases were macroscopically examined. Samples of primary tumors, their local lymph nodes, lungs and main organs such as liver, kidneys, spleen were taken for histological examination. Forty-two percent of control mice exhibited lung metastases and 27% possessed metastases in local lymph nodes whereas 24% of vitamin-treated mice exhibited lung metastases and 10% possessed local lymph nodes metastases. The total number of lung metastases was 19 in control group and 10 in vitamin C and K(3)-treated mice. Histopathological examination of the metastatic tumors from the vitamin-treated mice revealed the presence of many tumor cells undergoing autoschizic cell death. These results demonstrate that oral vitamin C and K(3) significantly inhibited the metastases of T.L.T. tumors in C3H mice. At least a portion of this inhibition was due to tumor cell death by autoschizis.

    Adenocarcinomas of esophagus and cardia represent in France approximately 20 to 40% of the esophagus cancers. They have a high risk to develop lymph nodes metastases and liver metastases. Currently, only 50 to 70% of patients may benefit from surgical curative resection at diagnosis, but more than 50% of them will recur. The standard of treatment of these metastatic adenocarcinomas is chemotherapy. Three large randomized comparative studies, between chemotherapy and supportive care, showed that chemotherapy significantly extends the median of survival (from 3-4 months to 10-12 months) and improves the quality of life. Currently, the combination of epirubicin-cisplatin-continuous 5FU (ECF) is the most effective regimen but it is difficult to administer and tolerate because of the long continuous 5FU infusion. In France, the most commonly used combination regimen still associates 5FU and cisplatin. New drugs (such as docetaxel, CPT11, oxaliplatin) used alone or in combination, especially with 5U, are very promising. Radio-chemotherapy is the preferred treatment for locoregional recurrences, because it improves dysphagia and enables to obtain complete tumor responses. Current results from concomitant radio-chemotherapy studies for esophagus cancer, based on 5FU alone, 5FU-cisplatin or 5FU-mitomycin, given as preoperative treatment or as exclusive treatment, support to use radio-chemotherapy for the treatment of loco-regional recurrences after surgical resection. Nevertheless, the optimal radio-chemotherapy schedule still remain to be defined (dose, duration, splitting of radiotherapy, choice of anticancer drugs). (authors)

  10. Synchronous Bone Metastasis From Multiple Myeloma and Prostate Adenocarcinoma as Initial Presentation of Coexistent Malignancies

    Full Text Available The radiographic appearance of bone metastases is usually determined by tumor histology and can be osteolytic, osteoblastic, or mixed. We present a patient with coexistent bone metastasis from multiple myeloma and prostate adenocarcinoma who exhibited synchronous bone involvement of both histologies within the same bone lesion, a rare phenomenon that has not been previously reported and led to atypical radiographic findings. The radiograph of a 71-year-old man with thigh swelling and pain demonstrated a lytic femoral lesion. Magnetic resonance imaging (MRI confirmed a destructive process, but showed coexistent metaphyseal sclerosis. Multiple myeloma was suspected by demonstration of monoclonal gammopathy and confirmed by computed tomography (CT-guided biopsy. Incidentally, CT demonstrated areas of sclerosis corresponding to T2 hypointensity on MRI. Further studies revealed osteoblastic spinal metastasis, prostate enhancement on CT and prostate-specific antigen (PSA level of 90 ng/mL, concerning for concomitant prostate neoplasm. After endoprosthetic reconstruction, pathology of the femur identified both plasma cell neoplasm and metastatic prostate adenocarcinoma. An association between prostate cancer and multiple myeloma is hypothesized due to tumor microenvironment similarities and possible common genetic variations, however, coexisting bone metastases have never been reported. This unusual finding explains the discrepant imaging features in our patient and is evidenced that certain clinical situations merit contemplation of atypical presentations of common malignancies even if this leads to additional testing.

    Ovarian carcinoma is the fourth most common malignant disease of women. Types of ovarian carcinoma, including serous, mucinous, endometrioid, and transitional carcinoma, differ from each other with respect to morphology, genetic alterations and in their clinical course.Ovary is a common site for tumour metastases with 5-30% of ovarian cancers metastatic in nature. Differentiating primary from metastatic mucinous ovarian adenocarcinoma is often challenging. We assessed the usefulness of colonoscopy to sort out this dilemma. Methods: In this case-series with retrospective data collection at a tertiary care hospital in Pakistan, demographics, indication for referral, tumour size, laterality, and the immuno-histochemical stains were recorded. Results: A total of 17 patients were referred to gastroenterology department between March 2009 and March 2012. Mean age of the patients was 36.7 years (range, 16-58 years) and the indication for referral was mucinous pathology. All of these patients had surgery outside hospital; histopathology was submitted at our pathology laboratory for review. Out of 17 patients, 16 had progressive abdominal distension as the primary symptom whereas one patient had a history of bleeding per rectum; 67% (12/17) of the tumours were more than 10cm and 94% (16/ 17) were unilateral. We were able to find the colorectal primary in 17.4% (3/17) of the patients, whereas upper GI endoscopies were unrevealing all patients. CK-7 was positive in two of three and CK-20 was positive in all the three patients with colorectal primary. Conclusion: We were able to identify gastrointestinal primary in significant number of patients without gastrointestinal symptoms that showed immuno-histochemical stain pattern of primary mucinous adenocarcinoma and had a tumour size of greater than 10cm and were unilateral.

    Survival data, prognostic factors, and patterns of failure were retrospectively analyzed for a total of 76 patients with adenocarcinoma of the uterine cervix treated between January 1981 and December 1987, which represents 4.1% of all primary cervical carcinomas treated, at Department of Radiation Oncology, Yensei Cancer Center, Yonsei University College of Medicine. The mean age of the patients was 49years(range, 27-79years) and the peak incidence was in the group 50 to 59years of age. More half of the patients were postmenopausal (46/76=60.5%). Most patients(76%)had abnormal vaginal bleeding either alone or in combination with other symptoms. The proportion of stage Iib was 43.4%. There were 4 major histologic subtypes: pure adenocarcinoma(48/76=63.2%), adenosquamous carcinoma(20/76=26.3%), papillary (5/76=6.6%) and clear cell carcinoma(3/76=3.9%). Of the many clinicopathologic variables evaluated for prognosis, the most significant prognostic factors were stage of disease and the size of tumor. The overall 5-year survival rate was 68%, and the 5-year survival rates for stage Ib, II and III were 90%, 66% and 54%, respectively. Control of pelvic tumors was achieved in 938%, 90.2% and 50.0% of cases of stage Ib, II and III disease, respectively. In present study, treatment modalities (radiation therapy alone/combined operative and radiation therapy) did not affect the local control of tumor and the survival

    Adenocarcinoma of small bowel is generally a rather rare primary tumour of small bowel with a prevalence rate of 0.5 - 3.0 / 100.000 population, but the most frequent tumour of small intestine. It more often involves the duodenum and jejunum than the ileum. The aim of this paper is also to point out the value of small bowel follow through (SBFT) in the diagnosis of stenosing lesions. An 83 - year old male patient suffered from abdominal pain, malaise, vomiting, cachexia and diarrhoea for 3 months. The result of occult blood testing was negative. Haemoglobin level was normal. Proctoscopy, colonoscopy, upper gastrointestinal (GI) endoscopy, and ultrasonography (US) did not explain the patient's problems. Ileus of the small bowel was established with abdominal plain film. Small bowel follow through (SBFT) and computer tomography (CT) showed a stenosing tumour in the jejunum. Adenocarcinoma of the small bowel was established with histological examination after resection of the tumor. SBFT, with manual compression of all segments of the small bowel, can be a very accurate diagnostic investigation for evaluation of stenosing lesions in this part of the intestine. (author)

    2018-02-01

    Full Text Available SATB2 (Special AT-rich sequence-binding protein 2 has recently been shown to be a specific biomarker of colorectal cancer (CRC. The aim of this study was to investigate the diagnostic potential of SATB2 as a means of detecting a CRC origin for liver metastases. SATB2 expression was examined in a resection cohort of 101 CRC and 273 non-CRC adenocarcinoma samples using immunohistochemistry (IHC. The diagnostic accuracy of CRC origins of liver metastases based on SATB2 and a three marker panel of SATB2, CK20 and CDX2 was evaluated using an independent cohort of 192 liver biopsies. IHC showed 97 of the 101 (96.0% primary CRC samples were SATB2 positive, compared to only 6 of the 273 (2.1% samples of other cancer types. The sensitivity, specificity and AUC values of SATB2 expression in resection samples were 97%, 97.1% and 0.977, respectively. Meanwhile, for the liver biopsy samples, the sensitivity, specificity and AUC values of a CRC liver metastases was 92.2%, 97.8% and 0.948 for SATB2, 95.1%, 91.0% and 0.959 for CK20, and 100%, 85.4% and 0.976 for CDX2, respectively. Further analysis demonstrated that all three-marker positivity was detected in 92/103 (89.3% CRC and 2/89 (2.2% non-CRC liver metastases sampled by biopsy. Our findings suggest that SATB2, as measured by IHC, could serve as a promising diagnostic biomarker of CRC metastases. Combining evaluation of SATB2 with CK20 and CDX2 to form a three marker panel further improved the detection of metastatic CRCs in liver biopsy tissues.

    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.

    Purpose: To determine the efficacy and safety of radiosurgery in patients with large brain metastases treated with radiosurgery. Patients and Methods: Eighty patients with large brain metastases (>14 cm 3 ) were treated with radiosurgery between 1998 and 2009. The mean age was 59 ± 11 years, and 49 (61.3%) were men. Neurologic symptoms were identified in 77 patients (96.3%), and 30 (37.5%) exhibited a dependent functional status. The primary disease was under control in 36 patients (45.0%), and 44 (55.0%) had a single lesion. The mean tumor volume was 22.4 ± 8.8 cm 3 , and the mean marginal dose prescribed was 13.8 ± 2.2 Gy. Results: The median survival time from radiosurgery was 7.9 months (95% confidence interval [CI], 5.343–10.46), and the 1-year survival rate was 39.2%. Functional improvement within 1–4 months or the maintenance of the initial independent status was observed in 48 (60.0%) and 20 (25.0%) patients after radiosurgery, respectively. Control of the primary disease, a marginal dose of ≥11 Gy, and a tumor volume ≥26 cm 3 were significantly associated with overall survival (hazard ratio, 0.479; p = .018; 95% CI, 0.261–0.880; hazard ratio, 0.350; p = .004; 95% CI, 0.171–0.718; hazard ratio, 2.307; p = .006; 95% CI, 1.274–4.180, respectively). Unacceptable radiation-related toxicities (Radiation Toxicity Oncology Group central nervous system toxicity Grade 3, 4, and 5 in 7, 6, and 2 patients, respectively) developed in 15 patients (18.8%). Conclusion: Radiosurgery seems to have a comparable efficacy with surgery for large brain metastases. However, the rate of radiation-related toxicities after radiosurgery should be considered when deciding on a treatment modality.

    Objective: To evaluate MR imaging findings of uveal metastases. Methods: MR imaging findings of 20 cases with uveal metastases comfirmed by pathology or follow-up were retrospectively analyzed. MR imaging was performed in 20 patients, of which postcontrast T 1 -weighted imaging was performed in 19 patients including dynamic contrast enhancement scanning in four cases. Results: Metastatic tumor was found in the iris and ciliary body in two cases, and in choroid in 18 cases. The tumor demonstrated slightly hypointense signal on T 1 -weighted imaging and isointense signal on T 2 -weighted imaging in two cases, isointense signal on T 1 -weighted imaging and isointense signal on T 2 -weighted imaging in nine cases, isointense signal on T 1 -weighted imaging and slightly hyperintense signal on T 2 -weighted imaging in three cases, isointense signal on T 1 -weighted imaging and slightly hypointense signal on T 2 - weighted imaging in three cases, slightly hyperintense signal on T 1 -weighted imaging and slightly hypointense signal on T 2 -weighted imaging in two cases, and slightly hyperintense signal on T 1 -weighted imaging and slightly hyperintense signal on T 2 -weighted imaging in one case. The tumor appeared as mild thickness of the wall of the globe in eight cases, a crescent mass in three cases, a fusiform mass in seven cases, and a nodule in two cases. Nineteen patients showed moderate or marked enhancement on postcontrast T 1 -weighted imaging. The time-intensity curve of dynamic contrast enhancement in four patients suggested a rapid enhancement and slow washout pattern. Retinal detachment was observed in 11 patients and abnormal signal intensity within the vitreous body was seen in two cases. Conclusion: MRI can display the location, shape, signal characteristics, and enhancement pattern of uveal metastases, contributing to diagnosis and differential diagnosis. (authors)

    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.

    Full Text Available RACIONAL: Metástases podem ser a primeira manifestação de adenocarcinoma. Cerca de 60% destas podem ser cutâneas e correspondem a casos de neoplasia em estágio avançado. A procura pelo sítio primário é onerosa, sendo necessário o emprego de diversos exames de imagem, endoscópicos e imunoistoquímicos. Apesar disto, o sítio primário é descoberto somente em 15% a 20% dos pacientes, sendo os demais casos reconhecidos nas autopsias. OBJETIVO: Relatar um caso de adenocarcinoma, moderadamente diferenciado metastático cutâneo, de sítio primário desconhecido. A região acometida foi a pele da fossa ilíaca esquerda. RESULTADOS: A lesão foi ressecada cirurgicamente. O sítio primário não foi identificado por nenhum exame de imagem ou endoscópico. O estudo imunoistoquímico revelou o seguinte padrão de imunoperoxidase: CEA negativo, CK7 positivo, CK20 negativo e PSA negativo. Com base nestes achados, foram afastados tumores primários do intestino grosso e da próstata (PSA, CK20 e CEA negativos. Os principais sítios primários aventados foram pâncreas e vias biliares. CONCLUSÃO: A procura pelo sítio primário de adenocarcinoma metastático continua sendo tarefa difícil, onerosa e com pouco impacto no tratamento dos pacientes acometidos.BACKGROUND: Metastases may be the first manifestation of adenocarcinoma. Up to 60% are cutaneous and present in advanced stage neoplasms. Research for the primary site is costly and requires endoscopy, imaging and immunohistochemical exams.

    To assess the frequency of osteosclerotic changes on CT that appeared after treatment with gefitinib in patients with lung adenocarcinoma and the relationship between the osteosclerotic changes and the response to the therapy. Our study included 41 patients with lung adenocarcinoma who underwent chest CT both before (CTpre) and after (CTpost) starting treatment with gefitinib. The presence or absence of bone metastases was assessed on the CTpre, and the interval bony change after the therapy was classified as lytic, sclerotic, or no changes on the CTpost. The relationship between treatment results of primary lung cancer and interval bony changes was evaluated. Osteosclerotic lesions were identified in 11 patients (27%) on CTpost; in 6 of 11 patients osteosclerotic lesions newly appeared where the CTpre showed no bone metastasis before the gefitinib therapy. There were significant differences in the therapeutic response of the primary cancers (P < 0.001) and in the survival rate (P < 0.01) in patients with osteosclerotic changes versus those without osteosclerotic changes. Osteosclerotic changes on CT, observed after gefitinib treatment in patients with lung adenocarcinomas, may be an indicator of a good therapeutic response. (orig.)

    Full Text Available Abstract Background CREST (Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly and Telangiectasias syndrome has been rarely associated with other malignancies (lung, esophagus.This is the first report of a primary adenocarcinoma of the third portion of the duodenum in a patient with CREST syndrome. Case presentation A 54-year-old male patient with CREST syndrome presented with colicky postprandial pain of the upper abdomen, diminished food uptake and a 6-Kg-body weight loss during the previous 2 months. An ulcerative lesion in the third portion of the duodenum was revealed during duodenoscopy, with a diagnosis of adenocarcinoma on biopsy specimen histology. The patient underwent a partial pancreatoduodenectomy. No adjuvant therapy was instituted and follow-up is negative for local recurrence or metastases 21 months postoperatively. Conclusion CREST syndrome has been associated with colon cancer, gastric polyps, familial adenomatous polyposis (FAP syndrome and Crohn's disease; however, this is the first report of a primary adenocarcinoma of the duodenum in a patient with CREST syndrome. However, any etiologic relationship remains to be further investigated.

    Pancreatic cancer in young adults is very rare. We report a case of young-onset poorly differentiated pancreatic ductal adenocarcinoma with rapid progression and poor prognosis in a 31-year-old Japanese man with no obvious family history of malignancy. Preoperative examinations revealed a mass lesion in the body of the pancreas, accompanied by a slightly dilated main pancreatic duct distal to the mass lesion. Pancreatic cancer with acute pancreatitis was suspected because of an elevation of serum pancreatic enzyme and tumor marker, along with imaging findings. Distal pancreatectomy with resection of the common hepatic artery and splenectomy along with lymph node dissection was performed. Microscopically, the tumor was mainly composed of poorly differentiated ductal adenocarcinoma. The postoperative course was uneventful, but the patient had multiple liver metastases 2 months postoperatively, in spite of adjuvant chemotherapy, and died 8 months postoperatively. This case may represent a rare instance of young-onset poorly differentiated ductal adenocarcinoma with rapid progression and may indicate potential risk factors of pancreatic cancer in young adults.

    Gestational trophoblastic neoplasm (GTN), choriocarcinoma in coexistence with primary cervical adenocarcinoma, is a rare event not easy to diagnose. Choriocarcinoma is a malignant form of GTN but curable if metastases do not appear early and spread fast. We presented choriocarcinoma in coexistence with primary cervical adenocarcinoma in a 48-year-old patient who had radical hysterectomy because of confirmed cervical carcinoma (Dg: Carcinomaporo vaginalis uteri FIGO st I B1). Histological findings confirmed cervical choriocarcinoma with extensive vascular invasion and apoptosis but GTN choriocarcinoma was finally confirmed after immunohystochemical examinations. Preoperative serum human gonadotropine (beta hCG) level stayed unknown. This patient did not have any pregnancy-like symptoms before the operation. The first beta hCG monitoring was done two months after the operation and found negative. According to the final diagnosis the decision of Consilium for Malignant Diseases was that this patient needed serum hCG monitoring as well as treatment with chemotherapy for high-risk GTN and consequent irradiation for adenocarcinoma. The early and proper diagnosis of nonmetastatic choriocarcinoma of nongestational origine in coexistence with cervical carcinoma is curable and can have good prognosis.

    Many reports have shown a link between human papillomavirus (HPV) and cervical squamous neoplasia. However, the association of HPV with cervical adenocarcinoma has been studied less extensively. The authors evaluated the presence of HPV-DNA in 106 patients with adenocarcinoma of the uterine cervix by in situ hybridization, using 35 S-labeled probes for HPV 16 DNA and HPV 18 DNA. The overall prevalence of HPV-DNA was 18% (19 of 106). HPV 16 was present in 2 (2%) cases, HPV 18 was observed in 15 (14%) cases, and both HPV 16 and HPV 18 were found in 2 (2%) cases. There was a correlation between HPV-DNA positivity and tumor stage (P less than 0.01) and tumor size (P less than 0.05), but there was no relationship between HPV-DNA positivity and tumor differentiation, proliferation (S-phase fraction), ploidy, lymph node metastases, or five-year survival rate. These results suggest that HPV 18 DNA is associated with cervical adenocarcinoma but the presence of HPV 18 has no influence on overall survival

    We describe a case of pancreatic adenocarcinoma and Brunner's gland adenoma in an 18-year-old male Siberian tiger (Panthera tigris altaica) from the Ljubljana Zoo. The tiger was humanely destroyed due to weakness and progressive weight loss. Necropsy examination revealed a large, grey, predominantly necrotic mass replacing the major part of the pancreatic body. Microscopically, the mass was unencapsulated, poorly demarcated, highly cellular and composed of highly pleomorphic, cuboidal to tall columnar cells with basal, round or oval, moderately anisokaryotic nuclei with prominent nucleoli and moderate to large amounts of eosinophilic cytoplasm. The tumour was diagnosed as pancreatic tubular adenocarcinoma with infiltration into the duodenum and mesentery. There were tumour emboli in mesenteric blood vessels and hepatic metastases. The non-affected part of the pancreas exhibited severe chronic pancreatitis. In addition, one firm white neoplastic nodule was observed in the duodenal wall. The nodule was set in the tunica muscularis and was unencapsulated, well demarcated and highly cellular, and consisted of a closely packed layer of normal Brunner's glands and a centrally positioned group of irregularly branched tubules with small amounts of debris in the lumen. The neoplastic nodule was diagnosed as Brunner's gland adenoma. The present case is, to the best of our knowledge, the first report of concurrent pancreatic adenocarcinoma and Brunner's gland adenoma, most probably induced by chronic pancreatitis, either in man or animals.

    Bone is the most common metastatic site associated with breast cancer. Using a database of women with breast cancer treated at Guy's Hospital, London 1976-2006 and followed until end 2010, we determined incidence of and survival after bone metastases. We calculated cumulative incidence of bone metastases considering death without prior bone metastases as a competing risk. Risk of bone metastases was modelled through Cox-regression. Survival after bone metastases diagnosis was calculated using Kaplan-Meier methodology. Of the 7064 women, 589 (22%) developed bone metastases during 8.4 years (mean). Incidence of bone metastases was significantly higher in younger women, tumour size >5 cm, higher tumour grade, lobular carcinoma and ≥ four positive nodes, but was not affected by hormone receptor status. Median survival after bone metastases diagnosis was 2.3 years in women with bone-only metastases compared with early, and proportionately fewer patients in this group. Incidence of bone metastases has decreased but bone metastases remain a highly relevant clinical problem due to the large number of patients being diagnosed with breast cancer.

    Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR); eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases)

    It has unfortunately remained true that radionuclide renal imaging studies have not been so widely accepted as other types of scintigraphy, despite improvements in radiopharmaceuticals and imaging techniques. Perhaps this is because of the variety of established radiologic techniques available for the study of the kidneys and the addition of new modalities such as CT scanning and ultrasound. Clinicians may have become confused by the multiplicity of options, which has obscured the distinction between renal scintigraphy and all other methods of imaging the kidney, i.e., that renal scintigraphy provides functional information in an easily quantifiable form. It is interesting that pediatric practitioners have more easily recognized the functional importance of this modality than have the practitioners of adult medicine, who more often prefer anatomic modalities, either traditional or new

    Iris metastasis in patients with gastric cancer is extremely rare. Herein, it is aimed to report on a patient with gastric adenocarcinoma and iris metastasis. A 65-year-old patient with the history of gastric cancer was admitted for eye pain and eye redness on his left eye. There was ciliary injection, severe +4 cells with hypopyon in the anterior chamber and a solitary, friable, yellow-white, fleshy-creamy vascularized 2 mm × 4 mm mass on the upper nasal part of the iris within the left eye. The presented patient's mass lesion in the iris fulfilled the criteria of the metastatic iris lesion's appearance. The ocular metastasis occurred during chemotherapy. Iris metastasis can masquerade as iridocyclitis with pseudohypopyon or glaucoma. In patients with a history of gastric cancer that present with an iris mass, uveitis, and high intraocular pressure, ocular metastasis of gastric cancer should be a consideration.

    The annular pancreas is a congenital anomaly in which pancreatic tissue partially or completely surrounds the second portion of the duodenum. Its often located above of papilla of Vater (85%), rarely below (15%). This pancreatic tissue is often easily dissociable to the duodenum but there is same cases where it the tissue is into the muscolaris wall of the duodenum. We describe three case of annular pancreas hospitalized in our facility between January 2004 and January 2009. There were 2 male 65 and 69 years old respectively and 1 female of 60 years old, presented complaining of repeated episodes of mild epigastric pain. Laboratory tests (including tumor markers), a direct abdomen X-ray with enema, EGDS and total body CT scan were performed to study to better define the diagnosis. EUS showed the presence of tissue infiltrating the muscle layer all around the first part of duodenum. Biopsies performed found the presence of pancreatic tissue with focal areas of adenocarcinoma. Subtotal gastrectomy with Roux was performed. The histological examinations shows an annular pancreas of D1 with multiple focal area of adenocarcinoma. (T1aN0M0). We performed a follow up at 5 years. One patients died after 36 months for cardiovascular hit. Two patients, one male and one female, was 5-years disease-free. Annular pancreas is an uncommon congenital anomaly which usually presents itself in infants and newborn. Rarely it can present in late adult life with wide range of clinical severities thereby making its diagnosis difficult. Pre-operative diagnosis is often difficult. CT scan can illustrate the pancreatic tissue encircling the duodenum. ERCP and MRCP are useful in outlining the annular pancreatic duct. Surgery still remains necessary to confirm diagnosis and bypassing the obstructed segment. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

    1997-01-01

    Purpose: This study aimed to analyze dose, initial pattern of enhancement, and other factors associated with freedom from progression (FFP) of brain metastases after radiosurgery (RS). Methods and Materials: All brain metastases treated with gamma-knife RS at the University of California, San Francisco, from 1991 to 1994 were reviewed. Evaluable lesions were those with follow-up magnetic resonance or computed tomographic imaging. Actuarial FFP was calculated using the Kaplan-Meier method, measuring FFP from the date of RS to the first imaging study showing tumor progression. Controlled lesions were censored at the time of the last imaging study. Multivariate analyses were performed using a stepwise Cox proportional hazards model. Results: Of 261 lesions treated in 119 patients, 219 lesions in 100 patients were evaluable. Major histologies included adenocarcinoma (86 lesions), melanoma (77), renal cell carcinoma (21), and carcinoma not otherwise specified (17). The median prescribed RS dose was 18.5 Gy (range, 10-22) and the median tumor volume was 1.3 ml (range, 0.02-30.9). The initial pattern of contrast enhancement was homogeneous in 68% of lesions, heterogeneous in 12%, and ring-enhancing in 19%. The actuarial FFP was 82% at 6 months and 77% at 1 year for all lesions, and 93 and 90%, respectively, for 145 lesions receiving ≥ 18 Gy. Multivariate analysis showed that longer FFP was significantly associated with higher prescribed RS dose, a homogeneous pattern of contrast enhancement, and a longer interval between primary diagnosis and RS. Adjusted for these factors, adenocarcinomas had longer FFP than melanomas. No significant differences in FFP were noted among lesions undergoing RS for recurrence after prior radiotherapy (119 lesions), RS alone as initial treatment (45), or RS boost (55). Conclusion: A minimum prescribed radiosurgical dose ≥ 18 Gy yields excellent local control of brain metastases. The influence of pattern of enhancement on local control, a

    Calcitonin and parathyroid hormone were determined using a radioimmunoassay in the blood serum of lung, breast and kidney cancer patients who had undergone combined treatment for major disease, healthy males, patients with spinal tuberculosis and patients with eosinophilic granuloma of the cranial bones. A significant rise of the calsitonin level and change in the ratio of calcitonin and the parathyroid hormone were established in the blood serum of patients with tumor metastases to the skeleton, spinal tuberculosis and eosiniphilic cranial granuloma. During cancer patients monitoring the determination of calcitonin is recommended as a screening test for sceletal metastases to select patients for γ-topographic investigation

    Metastases represent the most common brain tumors in adults. Surgical resection alone results in 45% recurrence and is usually accompanied by radiation and chemotherapy. Adequate chemotherapy delivery to the CNS is hindered by the blood-brain barrier. Efforts at delivering chemotherapy locally to gliomas have shown modest increases in survival, likely limited by the infiltrative nature of the tumor. Temozolomide (TMZ) is first-line treatment for gliomas and recurrent brain metastases. Doxorubicin (DOX) is used in treating many types of breast cancer, although its use is limited by severe cardiac toxicity. Intracranially implanted DOX and TMZ microcapsules are compared with systemic administration of the same treatments in a rodent model of breast adenocarcinoma brain metastases. Outcomes were animal survival, quantified drug exposure, and distribution of cleaved caspase 3. Intracranial delivery of TMZ and systemic DOX administration prolong survival more than intracranial DOX or systemic TMZ. Intracranial TMZ generates the more robust induction of apoptotic pathways. We postulate that these differences may be explained by distribution profiles of each drug when administered intracranially: TMZ displays a broader distribution profile than DOX. These microcapsule devices provide a safe, reliable vehicle for intracranial chemotherapy delivery and have the capacity to be efficacious and superior to systemic delivery of chemotherapy. Future work should include strategies to improve the distribution profile. These findings also have broader implications in localized drug delivery to all tissue, because the efficacy of a drug will always be limited by its ability to diffuse into surrounding tissue past its delivery source.

    From January 1974 to December 1980, 104 patients with brain metastases were treated by irradiation to the whole brain. The results of treatment and the relation between CT images and effectiveness of irradiation were analized. The lung was the most common site of the primary tumor (67/104, 64.4%). The breast was a distant second in frequency (13/104, 12.5%) and fewer cases had other primary tumors (24/104, 23.1%). There were 63 males and 41 females. Their mean age was 56.0 years old. The interval between onset of symptoms from primary disease and of those from the brain metastases were 26.5 months for the breast cancer, 7.6 months for undifferentiated carcinoma of the lung and 13.2 months for all patients. Significant neurologic improvement was obtained in 85.7% of the patients (86 cases) irradiated as previous plans. The survival for the entire group of patients (86 cases) was 60.5% at 3 months, 31.4% at 6 months, 11.6% at 12 months an 3.5% at 18 months. Multiplicity of the metastatic brain tumror did not affect the prognosis but the control of the primary lesion affected the prognosis. The CT images of 41 cases before treatment revealed the enhanced mass was mainly homogeneous for the case with the breast cancer and mainly ring like for the case with squamous cell carcinoma of the lung. But the characters of the enhanced mass did not affect the prognosis. On the other hand, the analysis of the CT images of 37 cases before and after the treatment revealed the relation between the tumor regression and the improvement in neurologic symptoms. (J.P.N.)

    Lung cancers are known to metastasize to unusual sites. Despite this knowledge often times the diagnosis of a primary lung cancer gets delayed especially when the patient presents without respiratory symptoms. The patient discussed in our review is a 47-year-old female, smoker who had presented to several hospitals with months of headache, nausea and intermittent episodes of vomiting. She was noted to have hypernatremia due to diabetes insipidus and a pituitary lesion on her magnetic resonance images. The pituitary mass on biopsy was found to represent a metastatic focus from a primary lung adenocarcinoma. Clinicians should be aware of malignancies that are well known to metastasize to the posterior pituitary. Conversely, since not every patient presents with symptoms of metastasis, there is a need to recognize the clinical syndromes (e. g., diabetes insipidus-like symptoms or more subtle symptoms like cranial nerve palsies) associated with potential metastasis to the pituitary.

    ROS1 fusion is a common genetic alteration in non-small-cell lung cancer. Crizotinib, an anaplastic lymphoma kinase inhibitor, shows efficacy in the treatment of lung cancer cases with ROS1 translocation. We report the response to crizotinib of a lung adenocarcinoma patient harboring a novel SLC34A2-ROS1 fusion variant, which was different from the two common SLC34A2-ROS1 fusion types reported in the literature. After crizotinib administration, overall recovery was good in this patient; the primary lesion was successfully treated, the lymph node metastases had disappeared, and the metabolism was normal.

    Surgical resection is the only curative option in patients with pancreatic ductal adenocarcinoma. Little is known about the oncologic outcomes of laparoscopic distal pancreatectomy. This bi-institutional study aimed to examine the long-term oncologic results of standard laparoscopic distal pancreatectomy in a large cohort of patients with pancreatic ductal adenocarcinoma. From January 2002 to March 2016, 207 patients underwent standard laparoscopic distal pancreatectomy for pancreatic ductal adenocarcinoma at Oslo University Hospital-Rikshospitalet (Oslo, Norway) and Asan Medical Centre (Seoul, Republic of Korea). After the exclusion criteria were applied (distant metastases at operation, conversion to an open operation, loss to follow-up), 186 patients were eligible for the analysis. Perioperative and oncologic variables were analyzed for association with recurrence and survival. Median overall and recurrence-free survivals were 32 and 16 months, while 5-year overall and recurrence-free survival rates were estimated to be 38.2% and 35.9%, respectively. Ninety-six (52%) patients developed recurrence: 56 (30%) extrapancreatic, 27 (15%) locoregional, and 13 (7%) combined locoregional and extrapancreatic. Thirty-seven (19.9%) patients had early recurrence (within 6 months of operation). In the multivariable analysis, tumor size >3 cm and no adjuvant chemotherapy were associated with early recurrence (P = .017 and P = .015, respectively). The Cox regression model showed that tumor size >3 cm and lymphovascular invasion were independent predictors of decreased recurrence-free and overall survival. Standard laparoscopic distal pancreatectomy is associated with satisfactory long-term oncologic outcomes in patients with pancreatic ductal adenocarcinoma. Several risk factors, such as tumor size >3 cm, no adjuvant chemotherapy, and lymphovascular invasion, are linked to poor prognosis after standard laparoscopic distal pancreatectomy.

  6. Homogeneous MGMT immunoreactivity correlates with an unmethylated MGMT promoter status in brain metastases of various solid tumors.

    Directory of Open Access Journals (Sweden)

    Barbara Ingold

    Full Text Available The O(6-methylguanine-methyltransferase (MGMT promoter methylation status is a predictive parameter for the response of malignant gliomas to alkylating agents such as temozolomide. First clinical reports on treating brain metastases with temozolomide describe varying effects. This may be due to the fact that MGMT promoter methylation of brain metastases has not yet been explored in depth. Therefore, we assessed MGMT promoter methylation of various brain metastases including those derived from lung (n = 91, breast (n = 72 kidney (n = 49 and from malignant melanomas (n = 113 by methylation-specific polymerase chain reaction (MS-PCR and MGMT immunoreactivity. Fifty-nine of 199 brain metastases (29.6% revealed a methylated MGMT promoter. The methylation rate was the highest in brain metastases derived from lung carcinomas (46.5% followed by those from breast carcinoma (28.8%, malignant melanoma (24.7% and from renal carcinoma (20%. A significant correlation of homogeneous MGMT-immunoreactivity (>95% MGMT positive tumor cells and an unmethylated MGMT promoter was found. Promoter methylation was detected in 26 of 61 (43% tumors lacking MGMT immunoreactivity, in 17 of 63 (27% metastases with heterogeneous MGMT expression, but only in 5 of 54 brain metastases (9% showing a homogeneous MGMT immunoreactivity. Our results demonstrate that a significant number of brain metastases reveal a methylated MGMT-promoter. Based on an obvious correlation between homogeneous MGMT immunoreactivity and unmethylated MGMT promoter, we hypothesize that immunohistochemistry for MGMT may be a helpful diagnostic tool to identify those tumors that probably will not benefit from the use of alkylating agents. The discrepancy between promoter methylation and a lack of MGMT immunoreactivity argues for assessing MGMT promoter methylation both by immunohistochemical as well as by molecular approaches for diagnostic purposes.

    The CT findings in 32 patients with pathologically proven metastases of the kidney were compared to findings in 74 patients with renal cell carcinoma. Fourteen CT criteria were chosen to describe and characterize the lesions and 2 radiologists evaluated the CT images retrospectively according to these criteria. Renal metastases were characterized as small, multiple, bilateral, wedge-shaped, less exophytic, and located within the renal capsule. Renal cell carcinomas were single, unilateral, nonwedge-shaped, and exophytic, and easily transgressed the renal capsule. The sensitivity of CT to discriminate renal cell carcinoma from renal metastasis was 93,2% for renal cell carcinoma, and to discriminate renal metastasis from renal cell carcinoma was 75,0% for renal metastases by computer posterior prohabilities. This study indicates that CT is usefull for distinguishing these clinically important tumors. By using posterior probability, some unnecessary biopsies may be avoided. (orig.)

    Brain metastases remain the commonest type of brain tumour, being four times more common than primary brain tumours. Although surgical intervention may be recommended for one of various reasons in the management of these tumours, including but not limited to conformation of diagnosis, relief of mass effect, improvement of neurological status and prolongation of survival, the guidelines for management of brain metastases remain largely subjective and therefore controversial. Herein the authors have attempted to review some of the existing evidence on role of surgery in the management of brain metastases and have presented their selected guidelines for the readers.

    The purpose of this paper is to present the epidemiology, diagnostic workup and treatment of renal cell carcinoma (RCC) with an emphasis on the Slovenian epidemiological data. RCC represents 2% of all cancers and is the third most common genitourinary tract tumour. It most frequently occurs among people of ages, between 50 and 60 years. Male patients are more prone to it than female. A number of environmental, occupational and genetic factors have been found to be associated with the development of RCC. Patients often have nonspecific symptoms and this is the reason why for half of them the disease is already metastatic when diagnosed. The most common sites of metastases are lungs (75%), followed by soft tissues (36%), bones (20%), liver (18%), skin (8%) and central nerve system (8%). In the evaluation of RCC multiple diagnostic procedures are needed with obligatory image diagnostics. Radical nephrectomy is still the mainstream treatment of localized disease. Nephron sparing techniques have been used in cases, where radical operation would result in an anephric patient. Efficient adjuvant therapy has not been discovered yet. Until recently interpherone and interleukin were the only known effective treatments for metastatic disease, but now new and more efficient biologic agents are being discovered. The most important prognostic factor for survival is stage at the beginning of treatment. The 5-year survival rate is 95% for patients with stage I disease, 88% for stage II, 59% for stage III and 20% for stage IV. (author)

    Purpose: To assess the efficacy and limitations of definitive chemoradiation for adenocarcinoma of the anal canal and to propose a treatment strategy that addresses the limitations of treatment. Methods and Materials: Between 1976 and 1998, 16 patients with localized adenocarcinoma of the anal canal were treated with radiotherapy with or without chemotherapy with curative intent. Available histologic slides were reviewed for evidence of primary adenocarcinoma of anal duct origin. The treatment results for these patients were compared with those of a group of patients with epidermoid histologic features who were all treated with definitive chemoradiation (55 Gy with concurrent 5-fluorouracil and cisplatin, n=92) between 1989 and 1998. The hospital records were reviewed for all patients. Patients with epidermoid carcinoma presented with more advanced primary tumors (42% vs. 19% Stage T3 or greater). All adenocarcinoma patients were treated with radiotherapy (median dose 55 Gy): 11 received concurrent 5-fluorouracil-based chemotherapy and 5 received radiotherapy alone. The initial surgical procedures included abdominoperineal resection, excisional biopsies (n=5), and local excision (n=1). Abdominoperineal resection was performed as salvage therapy after local recurrence in 5 patients. The Kaplan-Meier method was used to calculate 5-year actuarial pelvic control, distant disease control, disease-free survival, and overall survival. The median follow-up was 45 months (range 5-196) for patients with adenocarcinoma and 44 months (range 9-115) for patients with epidermoid histologic features. Results: Both local and distant recurrence rates were significantly greater in the adenocarcinoma patients. Of 16 patients with adenocarcinoma, 7 (5-year actuarial rate 54%) had recurrence at the primary site compared with 16 (5-year actuarial rate 18%) of 92 patients with epidermoid histologic features (p=0.004). Distant disease developed in more patients with adenocarcinoma (5-year

    Breast cancer has the highest rate of incidence among all types of cancer in women. Only ~0.43% of breast malignancies occur as a result of metastatic lesions from extramammary tumors. The present study reports an extremely rare case of transverse colon cancer metastasizing to the bilateral ovaries and the left breast. The patient was a 47-year old female, who had a lump in the left breast without axillary lymphadenopathy. Specimens obtained by core needle biopsy were submitted for hematoxylin and eosin examination, and results revealed that the lump was a poorly differentiated adenocarcinoma. Since the patient had elevated levels of the carcinoembryonic antigen and a medical history of a Krukenberg tumor metastasized from colon cancer, immunohistochemical examinations were applied. Results identified that caudal-related homeobox protein 2 and cytokeratin 20 were positively stained, whilst cytokeratin 7 was negatively stained. Therefore, this patient was diagnosed as having colon cancer that had metastasized to the bilateral ovaries and the left breast. As the life expectancy of patients with cancer is increasing, types of metastases that used to be seen as rare are increasingly becoming more common. For clinicians, diagnosis should be cautious, and differential diagnosis should always be kept in mind.

    1975-01-01

    For our study, where clinical and scintigraphic observation seldom lasts more than two years and where measurable metastases always exceed 1 cm 3 , the exponential model was adopted and our results were all calculated with GERSTENBERG's formula which gives an apparent doubling time. The liver metastases were measured on the scintigraphic image obtained, a more or less sharply limited blank which makes for a first difficulty of judgement. Two magnascanner V type PICKER 5-inch crystal scintigraphs were used, giving three images simultaneously by a transcriber made up of a stylus and a light spot built into the detection system. The isotope used is colloidal gold ( 198 Au) phagocytized by the Kuepfferian reticulo-endothelial system. The doubling time for liver metastase scintigraphic images calculated for fifteen patients having undergone one or more isotopic checks after a first metastase image was discovered range from 10 to 103 days [fr

    2006-12-01

    Full Text Available Adenocarcinoma arising in urinary bladder or prostatic urethra is uncommon. When they occur, the tumor can be mistaken for metastatic lesions, especially from the colon. Here we report the fifth case of a primary urothelial-type adenocarcinoma arising in the prostate which showed enteric differentiation. The patient was a 55 year-old male whose prostatic needle core biopsy showed a high grade adenocarcinoma which was initially thought to be metastatic colon cancer. A follow-up colonoscopy was unremarkable. Subsequent prostatectomy revealed a high grade adenocarcinoma which was positive for cytokeratins 7 and 20, carcinoembryonic antigen, CDX2, and high molecular weight cytokeratin, and negative for prostate specific antigen, prostate specific acid phosphatase and AMACR. A diagnosis of urothelial-type adenocarcinoma of the prostate was rendered. We review the literature regarding this entity, and discuss the differential diagnosis, emphasizing utility of immunohistochemistry in making the diagnosis. Finally, we speculate on the behavior of these rare tumors.

    Wilms' tumor is the most common renal neoplasm during childhood, but it rarely presents in adults and even less frequently involves both kidneys at onset. The preoperative diagnosis is difficult, although it should be suspected (despite the low incidence) in cases of renal masses that contain necrotic tissue, calcification or fat. We report the case of a 32-year-old woman who presented with bilateral kidney mass and lung metastases. The patient had never complained of urinary symptoms prior to this finding. (Author) 12 refs

    1984-01-01

    The results of treatment of hepatic metastases secondary to carcinoma of the breast, bronchus and gastrointestinal tract, are reported in 36 patients; asymptomatic improvement was obtained in 26 patients. The symptomatic relief of pain, anorexia, nausea, vomiting, weakness, fatigue, sweating and abdominal distention was accompanied by reduction in the size of the enlarged liver, by gain in body weight, and by improvement in liver function as measured by determination of the serum bilirubin, alkaline phosphatase, cholesterols and proteins, and by the bromsulphalein retention test, the prothrombin time, the cephalin flocculation test and the thymol turbidity. The method of treatment was supervoltage roentgen therapy alone in 22 cases; in 14 cases a single intravenous dose of nitrogen mustard (0.4 mg. per kilogram body weight) was given immediately before the first roentgen treatment. The whole liver, however large, was irradiated through opposed anterior and posterior fields, and the tumor dose ranged from 2,000 to 3,750 roentgens. The over-all time of treatment was eight days in 24 cases, fifteen days in 6 cases, and twenty-two days in 6 cases

    1993-01-01

    The role of palliative irradiation was analysed in 55 patients with liver metastases from colorectal, breast and lung cancer, treated with irradiation doses more than 10 Gy. In 47 patients irradiation alone was done. In 29 patients the disease involved not only the liver, but was disseminated. A mean dose of 23.8 Gy was delivered, with daily fractions of 1.5, 1.8 or 2 Gy. Complete and near complete pain relief was obtained in six and nine patients. Normalized and near normalized values of bilirubin serum levels were obtained in five and seven patients. Relief of pain as well as normalisation of cholestasis were significantly correlated with the irradiation doses applied. Median survival was 36.5 days for patients with lung cancer, 70.5 and 73 days for patients with breast and colorectal cancer. Irradiation doses given and the status of disease were significantly correlated to prognosis. In the majority of our patients with clinical symptoms, i.e. pain or cholestase, irradiation alone was sufficient for palliation of these symptoms. Prognosis is limited because of the disseminated state of disease in 62% of the patients. In a group of patients, suffering from colorectal cancer with good prognostic criteria, the simultaneous application of radiotherapy and systemic chemotherapy was able to increase significantly the survival with minor toxicity. The use of a three-dimensional treatment planning could optimize the radiotherapy, due to the dose-volume histogram analysis. (orig./MG) [de

    2013-02-01

    Full Text Available Background and objective Epidermal growth factor receptor (EGFR, a transmembrane protein, is a member of the tyrosine kinase family. Gefitinib, an EGFR tyrosine-kinase inhibitors, has shown a high response rate in the treatment of lung cancer in patients with EGFR mutation. However, significant differences in EGFR mutations exist among different ethnic groups. The aim of this study is to investigate the prevalence of EGFR mutations in Uighur lung adenocarcinoma patients by using a rapid and sensitive detection method and to analyze EGFR mutation differences compared with Han lung adenocarcinoma patients. Methods We examined lung adenocarcinoma tissues from 138 patients, including 68 Uighur lung adenocarcinoma patients and 70 Han lung adenocarcinoma patients, for EGFR mutations in exons 18, 19, 20, and 21 by using the amplification refractory mutation system (ARMS PCR method. The mutation differences between Uighur and Han lung adenocarcinoma were compared by using the chi-square test method. Results EGFR mutations were detected in 43 (31.2% of the 138 lung adenocarcinoma patients. EGFR mutations were detected in 11 (16.2% of the 68 Uighur lung adenocarcinoma patients and in 32 (45.7% of the 70 Han lung adenocarcinoma patients. Significant differences were observed in the EGFR mutations between Uighur lung adenocarcinoma patients and Han lung adenocarcinoma patients (P<0.001. Conclusion Our results indicate that the EGFR mutation in Uighur lung adenocarcinoma patients (16.2% is significantly lower than that in Han lung adenocarcinoma patients (45.7%.

    Full Text Available Primary adenocarcinoma of the duodenum is an extremely rare disease, and represents only 0.35 % of all gastrointestinal malignies. Early detection of the disease is dificult because doesn't have pathognomonic simptoms. The Whipple procedure is the optimal method of treatment. The authors relate one case of a adenocarcinoma of the duodenum in a 65- year-old white female with a history of abdominal pain for a six-month period, associated with postprandial fullness, vomiting and weight loss. Endoscopy showed a elevated tumor in the second part of the duodenum, with partial obstruction of the lumen. Histological study of endoscopic biopsies reveled a moderare differentiated adenocarcinoma of the duodenum. The treatment was surgical. The authors comment on the more important aspects of this pathology.

    A 56 year old nulliparous female Asian elephant (Elephas maximus) living at the zoological garden of Naples (Italy), with a clinical history of recurrent colic, was found in agonal state and humane euthanasia was elected. At necropsy the uterine body was moderately increased in size and the lumen was reduced due to a poorly demarcated and infiltrative neoplasm. Furthermore, multiple, whitish, firm nodules were present in both lungs. Histological examination of the uterine mass revealed epithelial cells arranged in tubular or solid pattern infiltrating the endometrium and the muscular layer. Immunohistochemical examination showed immunoreactivity of neoplastic cells to estrogen receptors antibody. Pulmonary lesions were histologically and immunohistochemically superimposable to the epithelial uterine neoplasm. A definitive diagnosis of uterine adenocarcinoma with pulmonary metastases was made.

    In addition to personal observations of 77 patients with one or more metastatic sites in the gastrointestinal tract, the authors reviewed over 1000 similar cases in the literature. The general radiologic aspects of each location (oesophagus, stomach, intestine, colon/rectum) are discussed. The pathophysiology of this type of metastasis explains the radiologic images obtained during barium transit examinations. The lymphatic type of spread observed in the oesophageal region in connection with carcinoma of the breast is the origin of stenosis of the middle third. The haematogenous type of diffusion encountered during melanomas creates intramural or intraluminal radiologic images. Two means of spread can be observed in the stomach. Haematogenous spread can result in frequently multiple and ulcerated nodular submucosal lesions from melanomas and bronchogenic carcinomas; it can also cause a more or less stenotic invasive image, especially in connection with carcinoma of the breast. Dissemination by means of the mesenteric reflections, and in particular around the gastrocolic ligament, explains the spread of a carcinoma of the transverse colon towards the stomach. The most frequent secondary sites in the gastrointestinal tract occur in the small intestine, the majority of these metastases being caused by pelvic tumours. Whether occurring in the small intestine or the colon, the patophysiology is similar: direct invasion by a non-contiguous primary carcinoma along the fascias and mesenteric attachments (more rarely by lymphatic permeation), dissemination by the peritoneal fluid or haematogenuous spread. In the first two types of dissemination cited, the image encountered is often hard to differentiate from radiation-induced lesions. (orig.)

    Full Text Available Anal adenocarcinoma is very rare and usually occurs in the elderly. We present a case of a 12-year-old girl with an anal margin painful tumor infiltrating the lower rectum, with perineal and vulvar permeation nodules and bilateral fixed inguinal and iliac lymph nodes. Histology showed anal adenocarcinoma with mucosecreting component and independent cells. She had no extra pelvic metastasis on CT scan. She underwent a colostomy and palliative care. This exceptional case challenges us on the diversity of forms of anal cancers that require a multidisciplinary approach. The precarious social context and the age of onset make it difficult to manage this rare cancer.

    Full Text Available Generalized lymphadenopathy is a rare manifestation of metastatic prostate cancer. Here, we report the case of a 59-year-old male patient with supraclavicular, mediastinal, hilar, and retroperitoneal and inguinal lymphadenopathy, which suggested the diagnosis of lymphoma. There were no urinary symptoms. A biopsy of the inguinal lymph node was compatible with adenocarcinoma, whose prostatic origin was shown by immunohistochemical staining with PSA. The origin of the primary tumor was confirmed by directed prostate biopsy. We emphasize that a suspicion of prostate cancer in men with adenocarcinoma of undetermined origin is important for an adequate diagnostic and therapeutic approach.

    Long-term survival after resection of metastases from pancreatic ductal adenocarcinoma is rare. A 54-year-old man underwent pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) with UICC staging pT3N1M0 followed by adjuvant chemotherapy with gemcitabine (GEM). Three years after radical resection of the primary tumor, a tiny nodule was found in the lower lobe of the left lung. Despite treatment with GEM, it increased gradually, but no other metastases were found. Eighteen months after the first indication of the nodule, wedge resection was performed. Pathological examination of the nodule indicated a metastatic tumor from PDAC. Pulmonary metastasectomy was again performed for lung oligometastases at 77 and 101 months after PD. The patient has been asymptomatic without tumor recurrence for 4 years since the last pulmonary resection. In PDAC, the treatment strategy for oligometastasis is controversial. However, a few cases of long-term survival after pulmonary metastasectomy for oligometastasis of PDAC have been reported. More such cases need to be studied to address this issue effectively.

    The incidence of kidney cancer has increased in the majority of countries worldwide, and this disease has relatively high lethality. For many years, the Slovak Republic has been among the countries with the highest kidney cancer incidence, in particular in 2012 (according to global estimated values) in both genders, although mainly in females. In the last few years, the Czech Republic has had the highest incidence of kidney cancer worldwide. The use of imaging techniques such as ultrasound and computerized tomography has increased the detection of asymptomatic renal cell cancer. Etiological factors include lifestyle factors such as smoking, obesity, and hypertension. Nephrectomy and partial nephrectomy are the standard treatments. Locally confined tumors in stage T1 should be treated with kidney-preserving surgery. Minimally invasive surgery is often possible as long as the surgeon has the requisite experience. For patients with metastases, overall and progression-free survival can be prolonged by pharmacotherapy with VEGF and mTOR inhibitors. The resection or irradiation of metastases can be a useful palliative treatment for patients with brain or osseal metastases that are painful or increase the risk of fracture. Minimally invasive surgery and new systemic drugs have expanded the therapeutic options for patients with renal cell carcinoma. The search for new predictive and prognostic markers is now in progress.Key words: kidney cancer - epidemiology - risk factors - pathology - diagnosis - therapy The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.

    Full Text Available In the English literature, only 9 cases of adenocarcinoma of the gallbladder with cutaneous metastasis have been reported so far. One case of multiple cutaneous metastases along with deposits in the breast tissue has been reported. We present a case of incidental metastatic gallbladder carcinoma with no intra-abdominal disease presenting as a series of four isolated cutaneous right chest wall, axillary nodal, breast and pulmonary metastases following resection and adjuvant chemoradiation for her primary tumor. In spite of the metastatic disease coupled with the aggressive nature of the cancer, this patient reported that her energy level had returned to baseline with a good appetite and a stable weight indicating a good performance status and now is alive at 25 months since diagnosis. Her serially-presented, oligometastatic diseases were well-controlled by concurrent chemoradiation and stereotactic radiation therapy. We report this case study because of its rarity and for the purpose of complementing current literature with an additional example of cutaneous metastasis from adenocarcinoma of the gallbladder.

    Full Text Available Abstract Background Complete remission from advanced-stage synchronous double primary (SDP esophageal and gastric adenocarcinoma by chemotherapy alone is rare. We report a case of advanced-stage SDP esophageal and gastric adenocarcinoma in which a complete response to treatment was obtained with S-1 and cis-diamminedichloroplatinum (CDDP. Case presentation The patient was a 74-year-old man referred to our hospital complaining of dysphagia. Gastrointestinal endoscopy was performed and advanced-stage SDP esophageal and gastric adenocarcinoma diagnosed. Computed tomography revealed multiple regional lymph node metastases in the mediastinum. Neoadjuvant chemotherapy with S-1 and CDDP for advanced esophageal and gastric cancer was planned. An endoscopy following two courses of chemotherapy revealed that the esophageal cancer had been replaced with a normal mucosal lesion and the gastric tumor with a scar lesion; the results of biopsies of both were negative for cancer. Computed tomography revealed that the multiple lymph node metastases had disappeared. We diagnosed a complete response to S-1 and CDDP in advanced-stage SDP esophageal and gastric cancer. The patient is still alive with no signs of recurrence 22 months after the disappearance of the original tumor and metastatic lesions without surgical treatment. Conclusion These results suggest that complete remission from advanced-stage esophageal and gastric cancer can be obtained with chemotherapy with S-1 plus CDDP.

    Malignant transformation of mediastinal mature teratoma is extremely rare and worsens the prognosis of the disease. Transformation can appear synchronously to or several years after the initial diagnosis. Clinical and radiological signs can orientate the clinician but the definitive diagnosis is obtained thanks to histology. An 11 year-old boy presented with a mediastinal mature teratoma and bone and pulmonary metastases. He received six cycles of chemotherapy combining etoposide, ifosfamide, cisplatin, followed by resection of a 16×14×9cm mediastinal mass. Karyotype analysis revealed the presence of an additional sex chromosome X (47 XXY) pathognomonic of Klinefelter's syndrome. Ten years later, sciatalgia revealed malignant transformation of a pre-existing sacral bone metastasis into gastrointestinal adenocarcinoma. The patient received four cycles of chemotherapy combining oxaliplatin, 5-fluorouracil and cetuximab. This treatment was followed by a complete resection of the sacral metastasis and completed with adjuvant irradiation of 54Gy in 30 daily fractions. Twelve months after the diagnosis of relapse, the patient remained alive without disease. To our knowledge, this is the first case of adenocarcinoma developed in bone metastases of a mediastinal mature teratoma in a boy with a Klinefelter's syndrome. We propose a review of the literature and an analysis of 20 others published cases of mediastinal teratoma with malignant transformation into adenocarcinoma.

    It is generally believed that patients with Hürthle cell thyroid carcinoma (HCTC) have a poor prognosis. Furthermore, distant metastases represent the most frequent cause of thyroid cancer-related death of patients with HCTC. The aim of this study was to report the treatment and outcomes of patients with distant metastases. Altogether 108 patients were treated for HCTC from 1972 to 2011 in our tertiary center and 32 patients (19 females, 13 males; median age 64.5 years) had either initially proven metastatic disease (N = 12) or distant progression of HCTC after initial treatment (N = 20). Patients with metastases were followed for 1–226 (median 77) months. Data were collected on the patients’ gender and age, extent of their disease, morphologic characteristics, therapy, outcome, and survival rate. Statistical correlation between possible prognostic factors and cause-specific survival from time of detection of metastases was analyzed by univariate analysis and log-rank test. The most common were lung metastases, followed by bone, mediastinum, kidney, and liver in 24, 8, 2, 1, and 1 case, respectively. Total thyroidectomy, lobectomy, subtotal thyroidectomy and neck dissection were performed in 19, 10, 3, and 7 patients, respectively. Radioiodine (RAI) ablation of thyroid remnant was performed in 30 patients, while 20 of them had RAI therapy (median 4 times). RAI uptake in metastases was present in 16 patients and ranged from 0.05 % to 12 %. Chemotherapy was used in 13 patients and external beam radiotherapy in 19 patients. Locoregional control of disease was achieved in 19/21 (90 %) cases who succumbed due to HCTC. Estimated 10-year disease-specific survival for all patients was 60 %. 10-year disease-specific survival for patients with pulmonary metastases and other sites metastases was 60 % and 62 %, respectively. 10-year disease-specific survival for patients with single organ and multiple organ metastases was 52 %, and 100 %, respectively. Estimated median

    Background. About 2% of patients with a carcinoma in one kidney develop either metastases or a new primary tumor in the contralateral kidney. Often, renal cancers progress rapidly at peripheral sites and a metastasis to the second kidney may not be the patient's main problem. However, when an initial renal cancer is more indolent yet spreads to the formerly unaffected kidney or a new primary tumor forms there, local treatment may be needed. Stereotactic body radiotherapy (SBRT) has been demonstrated as a valuable treatment option for tumors that cause local symptoms. Presented here is a retrospective analysis of patients in whom SBRT was used to control primary or metastatic renal disease. Patients and methods. Seven patients with a mean age of 64 (44-76) were treated for metastases from a malignant kidney to its contralateral counterpart. Dose/fractionation schedules varied between 10 Gyx3 and 10 Gyx4 depending on target location and size, given within one week. Follow-up times for patients who remained alive were 12, 52 and 66 months and for those who subsequently died were 10, 16, 49 and 70 months. Results. Local control, defined as radiologically stable disease or partial/complete response, was obtained in six of these seven patients and regained after retreatment in the one patient whose lesion progressed. Side effects were generally mild, and in five of the seven patients, kidney function remained unaffected after treatment. In two patients, the creatinine levels remained moderately elevated at approximately 160 μmol/L post treatment. At no time was dialysis required. Conclusion. These results indicate that SBRT is a valuable alternative to surgery and other options for patients with metastases from a cancer-bearing kidney to the remaining kidney and provides local tumor control with satisfactory kidney function

    1989-01-01

    A patient with primary adenocarcinoma of Bartholin gland is reported and the literatures relevant to this disease reviewed. Not only this disease is very rare but also primary carcinomas of Bartholin gland are misdiagnosed as cysts or abscesses in half of the cases, leading to considerable delay in diagnosis. And so, It was wasted long time before definitive therapy. However, because of a different clinical behavior, cancer of the Bartholin gland should be distinguished from other vulvar carcinomas. Histologically, squamous cell carcinoma and adenocarcinoma are the most common. Virtually all histologic types of Bartholin gland carcinoma metastasize to lymph node, bone, lung and liver in distant sites. The authors data and a review of the literature support the concept that radical vulvectomy with or without bilateral inguina1-femoral lymphadenectomy is required. On the other hand, except primary radiation treatment for small or medium sized cancers, the results obtained by radiation therapy in carcinoma of the vulva including Bartholin gland are generally discouraging. A role for postoperative adjuvant radiation therapy suggests because of high incidence of positive inguinal-femoral lymph nodes. In the near time, natural history and biological behavior of Bartholin gland cancer must be disclosed in detail. And also optimal treatment modality and prognostic factors shall be determine

    Full Text Available Abstract Background Lung cancer is known to metastasize to the pancreas with several case reports found in the literature, however, most patients are at an advanced stage and receive palliative treatment. Case presentation We describe the case of a 56 year old male patient who presented with a picture of obstructive jaundice. Investigations revealed an obstructing lesion in the pancreas and a further lesion in the lung with benign appearances. The patient underwent a pancreatectomy and, unexpectedly, the histology of the resected specimen demonstrated metastatic adenocarcinoma of bronchogenic origin. He was referred to a cardiothoracic team who proceeded to resect the patient's thoracic lesion before administration of adjuvant chemotherapy. The patient was reviewed 18 months post operatively and remains symptom free with no clinical or radiological evidence of recurrence. We were unable to identify any previous case reports (of lung adenocarcinoma with such a presentation which were ultimately treated with resection of both lesions. Conclusion Similar situations are bound to arise again in the future and we believe that this report could demonstrate that there is a case for aggressive surgical management in a highly selected group of patients: those with NSCLC and a synchronous solitary pancreatic deposit.

    1996-01-01

    Metastatic disease to the liver is an important disease from the diagnostic, prognostic and therapeutic points of view. Different imaging modalities, such as US, CT, scintigraphy, and MRI, have been used for detection, characterization, therapy planning, and follow-up of this disease with variable degrees of success and failure. This review handles the problems which face the different imaging modalities in diagnosis of liver metastases in view of the pathological background of the disease. It also discusses the indications, strong points, and shortcomings of each of the imaging modalities in diagnosis of metastases, and surveys the recent efforts done to improve their performance through the optimization of quality control and in the innovations in the field of contrast agents. Finally, a protocol is suggested for the clinical management of patients with liver metastases to optimize cost-effectiveness of the imaging modalities in this era of multimodality approach in diagnostic imaging.

    The guideline 'Brain Metastases', which was revised on behalf of the Dutch Society for Neuro-Oncology (LWNO), provides an excellent overview of levels of scientific evidence on diagnosis and treatment of patients with parenchymal brain metastases of solid tumours. I would like to emphasize, however, that this guideline is not a cookbook for facilitating individual physicians to treat patients on their own. It is important that every patient suffering from brain metastases is discussed by a multidisciplinary tumour board consisting of at least a neurologist, a neurosurgeon, a medical oncologist, a radiation oncologist, a pathologist and a radiologist, and that several crucial questions need to be explicitly asked and answered about every single patient.

    Metastases in the choroid of the eye are frequent in patients with disseminated malignancy. We here report the results using the precision radiotherapy technique described by Schipper et al. to treat 14 of 17 consecutive patients (21 eyes) with symptoms from such metastases. A beam defining collimator was used and a lateral field was given with the treated eye individually fixed. Varying fractionations and doses were used. The biologically effective dose for early effects (BED 3 ) was 47 to 90 Gy and for late effects (BED 10 ) 28 to 59 Gy. In 14 eyes (82%) the metastases regressed completely. The visual acuity was stabilized or improved in all patients and none needed local surgery. Three patients developed signs of radiation retinopathy, but only in one case the visual function was compromized. With this standardized technique no individualized dose planning was needed, the risk of radiation cataract was minimized and a dry eye avoided. (orig.)

Presence of either tumor necrosis or vascular invasion predicted development of metastases with a hazard ratio of 2.9 (95...... necrosis and vascular invasion were the major predictors of metastatic disease in this subset. Tumors with both these risk factors metastasized in 8 of 18 patients, which corresponds to a 12-fold increased risk of metastasis. These findings suggest that although small STS generally are linked to a good...... prognosis, necrosis and vascular invasion are features indicating biologically aggressive tumors for which treatment and surveillance should equal that for larger tumors....

    The horseshoe kidney is the most common congenital renal fusion anomalies. It occurs in 0.25% of the population, or 1 in every 400 people. It is more frequent in males (ratio 2:1). The most observed complication of horseshoe kidney is stone disease, although there may be others such as, abdominal pain, urinary infections, haematuria, hydronephrosis, trauma and tumours (most commonly associated with hypernephroma and Wilms tumour). We describe a case of a male patient with horseshoe kidney, stone disease and adenocarcinoma of the prostate. One carrier of this condition who suffered a transitional cell carcinoma of the prostate was found in a review of the literature.

    Objectives: The aim of this study is to determine MRI characteristics which indicate liver metastases of neuroendocrine tumors (NET) rather than metastases of other origin (non-NET). Methods: Sixty-nine patients with histopathologically proven liver metastases from NET and 69 patients with known liver metastases of other origin underwent MRI of the liver using a 1.5 T MR-scanner. Two board certified radiologists assessed presence of fluid–fluid-levels, number and distribution pattern, signal intensity (SI) characteristics, lesion homogeneity, presence of central necrosis and intratumoral hemorrhage in T2w and T1w non-contrast imaging. A multivariate logistic regression analysis was performed to determine the independent association of image findings and occurrence of NET. Results: Fluid–fluid-levels were identified in 19/69 of patients with NET-metastases, and in none of the patients in the control group (p < 0.0001). Hyperintense SI in T1w imaging, markedly hyperintense SI in T2w imaging, a disseminated distribution pattern and intratumoral hemorrhage were indicative of NET metastases (p < 0.05). After statistical adjustment for all significant MRI findings, fluid–fluid-levels (OR: 17.6, 95% CI: 1.9–166.5), strongly hyperintense SI in T2w (OR: 4.7, 95% CI: 1.8–12.7) and a disseminated distribution pattern (OR: 2.9, 95% CI: 1.1–7.4) were independent predictors for NET metastases. Conclusions: The presence of fluid–fluid-levels is highly indicative of NET liver metastases and can be used as an independent predictor to distinguish them from metastases of other origin

    Full Text Available Her2 overexpression and amplification can be found in a significant subset of esophageal adenocarcinomas. The activity of Her2 has been shown to be modulated by molecular chaperones such as HSP90. We analyzed expression/amplification data for HSP90 and Her2 on 127 primary resected esophageal adenocarcinomas in order to evaluate a possible relationship between these two molecules. HSP90 expression determined by immunohistochemistry was observed in various levels. Thirty nine (39 tumors (30.7% were classified as Her2-positive according to their immunoreactivity and amplification status. There was a significant correlation between HSP90 expression and Her2-status (p = 0.008. This could also be demonstrated by quantitative protein expression analysis with reverse phase protein arrays (r = 0.9; p < 0.001. Her2-status was associated withpT-category (p = 0.041, lymph node metastases (p = 0.049 and tumor differentiation (p = 0.036 with a higher percentage of cases with negative Her2 status in lower tumor stagesA negative Her2-status was also associated with better survival in univariate and multivariate analysis (p = 0.001 and p = 0.014. For HSP90, no associations between clinical and pathological parameters were found. The observed association between HSP90 expression and Her2 suggests a co-regulation of these molecules in at least a subset of esophageal adenocarcinomas. Anti-HSP90 drugs, which recently have been introduced in cancer treatment, may also be an option for these tumors by targeting HSP90 alone or in combination with Her2.

    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.

    Merkel cell carcinoma is an aggressive skin malignancy. Primary Merkel cell carcinomas are treated by wide radical excision with or without adjuvant radiotherapy, while benefits of adjuvant chemotherapy remain doubtful. There are only several cases of gastrointestinal metastases of Merkel cell carcinoma reported so far. We report a case of recurrent Merkel cell carcinoma with metastases to the stomach and the small intestines after wide excision of primary Merkel cell carcinoma.

    The authors have investigated 6 cases of bone metastases from cervical cancer out of a total of 90 cases of metastatic bone tumors that were irradiated for relief of associated pain at the Department of Radiology, Nagasaki University Hospital from April 1977 to March 1987. In 2 of the 6 cases, a rare, delayed recurrence with paraaortic lymph node metastases was seen. An invasion to the proasmajor muscle, iliomajor muscle was demonstrated by Computed Tomography after the initiation of therapy, so that the size of the field was modified. Computed Tomography was found useful to determine the exact field size for radiotherapy of metastatic bone tumor.

    Full Text Available A 15-year-old Pygmy doe was evaluated for acute onset of lethargy, anorexia, and weakness. Adrenal insufficiency was diagnosed based on physical exam findings, blood work abnormalities (hyponatremia, hyperkalemia, azotemia, and hypoglycemia, and lack of cortisol response to the ACTH stimulation test. Abdominal ultrasound exam revealed an intact urinary tract and multiple bilateral peri-renal masses. The doe was treated with intravenous fluid therapy aimed at correcting the electrolyte abnormalities and intravenous corticosteroids. She responded favorably to medical therapy in 24 hours, with dramatic improvement in attitude and appetite. Fluid therapy was discontinued, and the doe was discharged from the hospital on steroid supplementation. She deteriorated rapidly and died at home 36 hours after discharge. Necropsy results revealed metastatic adenocarcinoma originating from the uterus that infiltrated the urinary bladder, the region of the adrenal glands, the left and right renal lymph nodes, the left kidney, the caudal vena cava, the submandibular lymph nodes, the diaphragm, the lungs, and the omentum. Addison’s syndrome in ruminants should be considered as an uncommon sequel of intra-abdominal neoplastic processes.

    Objective: the aim of this study is to select the risk factors for local failure requiring salvage neurosurgery in patients with brain metastases treated with stereotactic radiosurgery in a single institution. Methods: the follow-up of 123 patients, with 255 brain metastases treated with radiosurgery at the Radiation Oncology Department of the Hospital Israelita Albert Einstein from July 1993 to August 2001, was retrospectively analyzed. The criteria for salvage neurosurgery were tumor volume enlargement, or tumor persistence leading to severe neurological symptoms, life threatening situation or critical steroid dependence. We considered the case as local failure when the histopathologic evaluation showed morphologically preserved cancer cells (tumor recurrence, persistence or progression). We applied the Fisher's exact test to evaluate the statistical correlation between local failure and primary tumor histology, volume of the brain metastases, prescribed radiosurgery dose, and whole brain radiotherapy. Results: fourteen of 123 patients (11%) underwent salvage neurosurgery. Histology showed preserved cancer cells with necrosis and/or bleeding in 11 cases (9% of the total accrual), and only necrosis with or without bleeding (without preserved cancer cells) in three cases. The primary tumor histology among the 11 patients considered with active neoplasia was malignant melanoma in five cases (21% of the patients with melanoma), breast adenocarcinoma in three (16% of the patients with breast cancer), and other histology in the remaining three. Breast cancer diagnosis, non-elective whole brain irradiation, volume of the brain metastases, and the prescribed radiosurgery dose did not correlate with the risk of local failure. Patients treated with elective whole brain radiotherapy showed fewer local failures, when compared to all patients receiving whole brain radiotherapy, and to the patients not receiving this treatment, with incidence of failure in 4%,7% and 14

    This was a phase I-II nonrandomized study that explored the toxicity and response of fractionated half-body irradiation (F-HBI) in patients with multiple symptomatic osseous metastases. The patients had no premedication and received 10 Gy in 5 fractions with a dose rate of 15 cGy/min. At the Cancer Institute Hospital, 9 patients were treated by this technique (1 upper and lower F-HBI, 6 upper F-HBI, 2 lower F-HBI). All patients were female and had adenocarcinomas (8 breast and 1 lung). Adverse effects were myelosuppression, vomiting and partial alopecia. But hematologic toxicity was treated with blood transfusion or G-CSF. All toxicity was transient, and no pneumonitis nor radiation-related deaths occurred. When given as palliation, F-HBI was found to relieve pain in 80% of the patients. In 10% of the patients the pain relief was complete. The mean time to achieve pain relief in responders after F-HBI was 9 days. The pain relief was long-lasting and continued without need of reirradiation for 40% of the remaining patient's life. This treatment modality appears to be well tolerated and effective in patients with multiple symptomatic osseous metastases. The optimal indications, dose and fractionation for F-HBI should be further explored in randomized trials. (author).

    Seventy consecutive patients with adenocarcinoma of the colon and rectum had a liver scan followed by surgical exploration of the liver. Preoperatively, blood chemistry studies were done in addition to palpation of the abdomen. Surgical findings were correlated to results of the liver scans, function tests and palpation of the liver. The overall concordance of liver scans with surgical findings was 78 percent. Thirty percent had false-positive results and 15 percent, false-negative results. The correlation of the liver scan with surgical findings was improved with increasing extent of metastases. When less than 25 percent of the liver was replaced by tumor, there was a random correlation of scan to surgical findings. By combining liver scans and liver function tests, metastases could be predicted with increased reliability only in patients who had severe metastatic disease of the liver. It is strongly recommended that patients with liver scans suggestive of metastatic disease and with most liver function tests within normal limits undergo exploration to establish the diagnosis. Exploratory laparotomy seems to be the only way to avoid chemotherapeutic treatment of patients with false-positive scans and still allow detection and treatment of metastases to the liver to occur at earlier stages

    The common sites of breast cancer metastases include bones, lung, brain, and liver. Renal metastasis from the breast is rare. We report a case of breast cancer metastatic to the kidney with extension into the renal vein. A 40-year-old woman had undergone left mastectomy for breast cancer at the age of 38. A gastric tumor, which was later proved to be metastasis from breast cancer, was detected by endoscopy. Computed tomography performed for further examination of the gastric tumor revealed a large left renal tumor with extension into the left renal vein. It mimicked a primary renal tumor. Percutaneous biopsy of the renal tumor confirmed metastasis from breast cancer. Surgical intervention of the stomach and the kidney was avoided, and she was treated with systemic chemotherapy. Breast cancer metastatic to the kidney may present a solitary renal mass with extension into the renal vein, which mimics a primary renal tumor.

    Highlights: • CT is more sensitive than PET/CT in detecting hepatic metastases. • PET/CT is more specific in detecting hepatic metastases. • CT and PET/CT have equal sensitivity in detecting extra hepatic metastases. • PET/CT is more specific in detecting extra hepatic metastases. • PET/CT has an impact of about 40% on changing the management strategies. - Abstract: Purpose: To investigate the efficacy of positron emission tomography/computed tomography (PET/CT) in detection and management of hepatic and extrahepatic metastases from gastrointestinal cancers. Materials and methods: Between February 2008 and July 2010, patients histopathologically diagnosed with gastrointestinal cancer and showing suspected metastasis on CT screening were subsequently evaluated with PET/CT. All patients were subgrouped according to histopathological origin and localization of the primary tumor. Localization of gastrointestinal cancers was further specified as lower gastrointestinal system (GIS), upper GIS, or hepato-pancreato-biliary (HPB). Both accuracy and impact of CT and PET/CT on patient management were retrospectively evaluated. Results: One hundred and thirteen patients diagnosed histopathologically with gastrointestinal cancers were retrospectively evaluated. Seventy-nine patients had adenocarcinoma and 34 patients other gastrointestinal tumors. Forty-one patients were in the upper GIS group, 30 patients in the HPB group, and 42 patients in the lower GIS group. Evaluation the diagnostic performance of PET/CT for suspected metastasis according to histopathological origin of the tumor, revealed that the sensitivity of PET/CT – although statistically not different – was higher in adenocarcinomas than in non-adenocarcinomas (90% (95% CI, 0.78–0.96) vs. 71.4% (95% CI, 0.45–0.88), P = 0.86). The specificity was not significantly different (85.7% (95% CI, 0.70–0.93) vs. 85% (95% CI, 0.63–0.94), P = 1.00). In the overall patient group; CT was significantly more

    2012-05-01

    Full Text Available Abstract Background In intestinal epithelium, tyrosine kinase receptor Ephrin B3 (Eph B3 maintains the architecture of the crypt-villus axis by repulsive interaction with its ligand ephrin-B1. While loss of Eph B3 is linked to colorectal cancer initiation, overexpression of Eph B3 in cancer cell lines inhibits growth and induces functional changes with decreased mesenchymal and increased epithelial markers. In order to study this tumor suppressor activity of Eph B3 in esophageal adenocarcinoma we analyzed the simultaneous expression of Eph B3 and E-cadherin in both the healthy esophagus and in Barrett’s carcinoma. Methods Simultaneous expression of Eph B3 and E-cadherin was investigated in samples from 141 patients with Barrett’s carcinoma and from 20 healthy esophagi using immunhistology and quantitative PCR. Results from healthy squamous epithelium, Barrett’s metaplasia and staging-specific esophageal adenocarcinoma were correlated. Results A significantly reduced E-cadherin mRNA expression could be detected in adenocarcinoma compared to dysplasia. The immunhistological activity of E-cadherin and Eph B3 was reduced in adenocarcinoma compared to dysplasia or healthy esophageal mucosa. The intracellular E-cadherin distribution changed significantly from the cytoplasm to the membrane, when the Eph receptor was simultaneously expressed. Simultaneous expression of E-cadherin and Eph B3 showed a significant inverse correlation to tumor stage. Conclusions We present novel evidence of the tumor suppressor activity of Eph B3 in esophageal adenocarcinoma possibly due to the impact on redistribution of cellular E-cadherin to the membrane. Our results suggest that this effect might play a role in the dysplasia-adenocarcinoma sequence, the infiltrative growth pattern and the development of lymph node metastases.

    Objective: To evaluate the effect of 153 Sm-EDTMP in treating patients with lung cancer and multiple bone metastases. Methods: A dose of 18.5-25.9 MBq/Kg 153 Sm-EDTMP was administered once a month to each patient through vein injection according to disease severity and body weight. 3 injections made up one therapy cycle. Results: Pain relieves were obtained in 65 patients, with an effective rate of 83.3%. Pain relief of grade I was observed in 19 patients (24.3%), grade II in 46 patients (59%) and grade III in 13 patients (16.7%), respectively. Lesions of bone metastases disappeared or shrunk in 9 patients, with a positive rate of 11.5%, which included 3 cases of grade I and 6 cases of grade II, respectively. Better effects were obtained in adenocarcinoma and squamous carcinoma than in small cell lung cancer. Conclusion: 153 Sm-EDTMP is safe and effective in treating patients with lung cancer and multiple bone metastases

    In order to detect and to evaluate the frequency, the distribution, and the radiological findings of skeletal metastases from hepatocellular carcinoma, the authors retrospectively analyzed radiographic, scintigraphic, and CT findings of 257 patients with hepatocellular carcinoma. The results were as follows: 1. Skeletal metastases were demonstrated in 21 patients (8.2%). 2. Frequent symptoms were pain, limitation of motion, paralysis, and mass. In nine of them the initial symptoms were due to skeletal metastases. 3. The common sites of metastases were spine (13 cases), ribs (8 cases), pelvis (8 cases) and femur (6 cases). Humerus, skull and sternum were also frequently involved. 4. Plain film findings were purely osteolytic in all cases and pathologic fractures were noted in 5 cases. 5. The lesions appear expansible in 7 cases, and 4 of them showed associated soft tissue masses on CT scans. 6. Bone scans were performed in 13 cases of them and showed increased radiotracer uptake in all. 7. Angiographic studies of 3 cases showed hypervascularity of the metastatic lesions as well as the primary hepatic tumor.

    Bone matastases are one of the most common and serious conditions requiring radiotherapy, but there is still a considerable lack of agreement on optimal radiation schedule. We analyzed patients with symptomatic osseous matastases from lung (72 patients) and breast (63 patients) carcinoma treated by palliative radiotherapy between 1983 and 1992. In this series, the incidences of symptomatic bone metastases appearing within 2 years after the first diagnosis of the primary lesion were 96% and 36% for lung and breast carcinomas, respectively. Thirty percent of bone metastases from breast carcinoma were diagnosed more than 5 years after the first diagnosis. Thus careful follow-up must be carried out for a prolonged period. Pain relief was achieved at almost the same rate for bone metastases from lung and breast carcinomas (81% and 85%, respectively), an the rapid onset of pain relief (15 Gy or less) was obtained in about half the patients for both diseases. The rapid onset of pain relief and the lack of association between the onset of pain relief and primary tumor argued against the conventional theory that tumor shrinkage is a component of the initial response. In contrast to the fact that almost all lung carcinoma patients had very poor prognoses, one third of the breast carcinoma patients were alive more than 2 years after palliative radiotherapy. Thust, the late effects of radiation, such as radiation myelopathy, must be always considered especially in breast carcinoma patients even when it is 'just' palliative radiotherapy for bone metastases.

    The management of brainstem metastases is challenging. Surgical treatment is usually not an option, and chemotherapy is of limited utility. Stereotactic radiosurgery has emerged as a promising palliative treatment modality in these cases. The goal of this study is to assess our single institution experience treating brainstem metastases with Gamma Knife radiosurgery (GKRS). This retrospective chart review studied 41 patients with brainstem metastases treated with GKRS. The most common primary tumors were lung, breast, renal cell carcinoma, and melanoma. Median age at initial treatment was 59 years. Nineteen (46%) of the patients received whole brain radiation therapy (WBRT) prior to or concurrent with GKRS treatment. Thirty (73%) of the patients had a single brainstem metastasis. The average GKRS dose was 17 Gy. Post-GKRS overall survival at six months was 42%, at 12 months was 22%, and at 24 months was 13%. Local tumor control was achieved in 91% of patients, and there was one patient who had a fatal brain hemorrhage after treatment. Karnofsky performance score (KPS) >80 and the absence of prior WBRT were predictors for improved survival on multivariate analysis (HR 0.60 (p = 0.02), and HR 0.28 (p = 0.02), respectively). GKRS was an effective treatment for brainstem metastases, with excellent local tumor control. PMID:24886816

    The advancement in oncology therapies has made brain metastases treatment a major factor influencing the survival time and quality of life of patients with cancer. Although there are numerous publications on the issue, there is not yet to be consensus regarding the best strategy for treatment, which is probably due to population heterogeneity in terms of functional status, type of neoplasia, control of the systemic disease, and the number and localization of the lesions in the central nervous system. Our objective is to present general recommendations based on rational analysis in order to guide the practical management of brain metastases. With this purpose, a multidisciplinary team composed by neurosurgeons, neuro-oncologists, neuro-pathologist, radio therapist and neurologists was brought together, conducting a thorough search, in english and spanish, for publications in Pub- Med from 1980 to July 2006 (the starting period was set at the beginning of use of RM in medical practice). Review and original articles with n= or >20 were selected. Also, book chapters of renowned authors in the different consulted areas were included. The assessment of the literature, in addition to the experience of the authors allowed for the development of the 'Consensus for the brain metastases treatment'. Finally, the authors expect the present work will contribute to the multidisciplinary approach for the management of brain metastases with simple and practical recommendations, and probably stimulating future developments in this field.

    Full Text Available Secondary osseous involvement in lymphoma is more common compared to primary bone lymphoma. The finding of osseous lesion can be incidentally discovered during the course of the disease. However, osseous metastases are infrequently silent. Detection of osseous metastases is crucial for accurate staging and optimal treatment planning of lymphoma. The aim of imaging is to identify the presence and extent of osseous disease and to assess for possible complications such as pathological fracture of the load-bearing bones and cord compression if the lesion is spinal. We are presenting two patients with treated lymphoma who were in complete remission. On routine follow-up contrast enhanced CT, there were new osteoblastic lesions in the spine worrisome for metastases. Additional studies were performed for further evaluation of both of them which did not demonstrate any corresponding suspicious osseous lesion. The patients have a prior history of chronic venous occlusive thrombosis that resulted in collaterals formation. Contrast enhancement of the vertebral body marrow secondary to collaterals formation and venous flow through the vertebral venous plexus can mimic the appearance of spinal osteoblastic metastases.

    Background: in the therapy of brain metastases there has been a great progress in the last years. It was shown, that more aggressive therapies can not only extend the survival of the patients, but also improve quality of life. The major question of this study was, whether surgery or stereotactic radiotherapy with the linear accelerator show better results in behalf of the survival. Beside this major question many parameters regarding the patient or his primary cancer were examined. Methods: from the 1st of January 1995 until the 30th of June 2000 233 patients with one or more brain metastases have been treated in the Wagner Jauregg Landesnervenkrankenhaus Oberoesterreich (WJ LNKH OeO). The LINAC has been established on the 1st of July 1997. The patients have been distributed in three groups: 1. LINAC-group: 81 patients have been treated from the 1st of July 1997 until the 30th of June 2000 with the LINAC. 2. Surgery-group: 81 patients have been operated from the 1st of July 1997 until the 30th June 2000. 3 Control-group: 71 patients have been operated from the 1st of January 1995 until the 30th of June 1997, before the LINAC has been established on the 1st of July 1997. Results: There are shown the mean survival times. Therapy options (0,05): LINAC-group: 377 days. Surgery-group: 195 days. Control-group: 285 days. Primary cancer (0,05): unknown primary: 203 days. Cancer of the colon tract: 218 days. Breast cancer: 314 days. Melanoma: 162 days. Kidney: 466 days. Lung 261 days. Others: 439 days. Metastases in one/in both hemispheres (0,05): in one hemisphere 310 days, in both 184 days. All the other parameters (age, sex, Karnofsky-Index, period between diagnose of the primary and the brain metastases, primary cancer therapy, extra cerebral metastases, number of metastases, localization of metastases supra- or infratentoriell, dose/effect relationship in the LINAC-group, whole brain radiotherapy) showed interesting differences, but the results were not statistically

    Our purpose was to analyze the long-term clinical outcome and to identify prognostic factors after Linac-based stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) on patients with brain metastases (BM) from non-small cell lung cancer (NSCLC). We performed a retrospective analysis of survival on 90 patients who underwent SRS or FSRT of intracranial NSCLC metastases between 04/2004 and 05/2014 that had not undergone prior surgery or whole brain radiotherapy (WBRT) for BM. Follow-up data was analyzed until May 2015. Potential prognostic factors were examined in univariable and multivariable analyses. The Golden Grading System (GGS), the disease-specific graded prognostic assessment (DS-GPA), the RADES II prognostic index as well as the NSCLC-specific index proposed by Rades et al. in 2013 (NSCLC-RADES) were calculated and their predictive values were tested in univariable analysis. The median follow-up time of the surviving patients was 14 months. The overall survival (OS) rate was 51 % after 6 months and 29.9 % after 12 months. Statistically significant factors of better OS after univariable analysis were lower International Union Against Cancer (UICC) stage at first diagnosis, histology of adenocarcinoma, prior surgery of the primary tumor and lower total BM volume. After multivariable analysis adenocarcinoma histology remained a significant factor; higher Karnofsky Performance Score (KPS) and the presence of extracranial metastases (ECM) were also significant. The RADES II and the NSCLC-RADES indices were significant predictors of OS. However, the NSCLC-RADES failed to differentiate between intermediate- and low-risk patients. The DS-GPA and GGS were not statistically significant predictors of survival in univariable analysis. The ideal prognostic index has not been defined yet. We believe that more specific indices will be developed in the future. Our results indicate that the histologic subtype of NSCLC could add to the prognostic

    Full Text Available Background: Brain metastases are a common manifestation of systemic cancer and exceed primary brain tumors in number and are a significant cause of neurologic problems. They affect 20-40% of all cancer patients. Aggressive management of brain metastases is effective in both symptom palliation and prolonging the life. Radiotherapy has a major role to play in the management of brain metastases. AIM: The aim of the study was to know the outcome of palliative radiotherapy in symptomatic brain metastases in terms of improvement in their performance status. Materials and Methods: This is a retrospective study of 63 patients diagnosed to have brain metastases and treated with palliative whole brain radiotherapy to a dose of 30 Gy in 10 fractions over two weeks between June 1998 and June 2007. Diagnosis was done in most of the cases with computed tomography scan and in a few with magnetic resonance imaging. Improvement in presenting symptoms has been assessed in terms of improvement in their performance status by using the ECOG scale. Results: Fifty-four patients completed the planned treatment. Eight patients received concurrent Temozolamide; 88% of patients had symptom relief at one month follow-up; 39/54 patients had a follow-up of just one to three months. Hence survival could not be assessed in this study. Conclusion: External beam radiotherapy in the dose of 30 Gy over two weeks achieved good palliation in terms improvement in their performance status in 88% of patients. Addition of concurrent and adjuvant Timozolamide may improve the results.

  9. Follistatin is a novel biomarker for lung adenocarcinoma in humans.

    Full Text Available Follistatin (FST, a single chain glycoprotein, is originally isolated from follicular fluid of ovary. Previous studies have revealed that serum FST served as a biomarker for pregnancy and ovarian mucinous tumor. However, whether FST can serve as a biomarker for diagnosis in lung adenocarcinoma of humans remains unclear.The study population consisted of 80 patients with lung adenocarcinoma, 40 patients with ovarian adenocarcinoma and 80 healthy subjects. Serum FST levels in patients and healthy subjects were measured using ELISA. The results showed that the positive ratio of serum FST levels was 51.3% (41/80, which was comparable to the sensitivity of FST in 40 patients with ovarian adenocarcinoma (60%, 24/40 using the 95th confidence interval for the healthy subject group as the cut-off value. FST expressions in lung adenocarcinoma were examined by immunohistochemical staining, we found that lung adenocarcinoma could produce FST and there was positive correlation between the level of FST expression and the differential degree of lung adenocarcinoma. Furthermore, the results showed that primary cultured lung adenocarcinoma cells could secrete FST, while cells derived from non-tumor lung tissues almost did not produce FST. In addition, the results of CCK8 assay and flow cytometry showed that using anti-FST monoclonal antibody to neutralize endogenous FST significantly augmented activin A-induced lung adenocarcinoma cells apoptosis.These data indicate that lung adenocarcinoma cells can secret FST into serum, which may be beneficial to the survival of adenocarcinoma cells by neutralizing activin A action. Thus, FST can serve as a promising biomarker for diagnosis of lung adenocarcinoma and a useful biotherapy target for lung adenocarcinoma.

  10. Appendiceal Adenocarcinoma Presenting as a Rectal Polyp

    Full Text Available Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively. The operative strategy had to be adjusted due to this unexpected finding. Although there are published cases of appendiceal adenocarcinoma inducing intussusception and thus mimicking a cecal polyp, there are no reports in the literature describing invasion of the appendix through the rectal wall and thus mimicking a rectal polyp. The patient is a 75-year-old female who presented with spontaneous hematochezia and, on colonoscopy, was noted to have a rectal polyp that appeared to be located within a diverticulum. When endoscopic mucosal resection was not successful, she was referred to colorectal surgery for a low anterior resection. Preoperative imaging was notable for an enlarged appendix adjacent to the rectum. Intraoperatively, the appendix was found to be densely adherent to the right lateral rectal wall. An en bloc resection of the distal sigmoid colon, proximal rectum and appendix was performed, with pathology demonstrating appendiceal adenocarcinoma that invaded through the rectal wall. The prognosis in this type of malignancy weighs heavily on whether or not perforation and spread throughout the peritoneal cavity have occurred. In this unusual presentation, an en bloc resection is required for a complete resection and to minimize the risk of peritoneal spread. Unusual appearing polyps do not always originate from the bowel wall. Abnormal radiographic findings adjacent to an area of

    To perform a retrospective analysis of patients with epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma who developed brain metastases (BM) to evaluate our hypothesis that the use of upfront EGFR-tyrosine kinase inhibitors (TKIs), and deferral of radiation therapy (RT), would result in inferior intracranial progression-free survival but similar overall survival (OS). Of 202 patients diagnosed with EGFR-mutant NSCLC between July 1, 2008, and December 31, 2014, 71 developed BM. Twenty-one patients were excluded owing to prior EGFR-TKI use, EGFR-TKI resistance mutation, failure to receive EGFR-TKI after whole-brain radiation therapy (WBRT)/stereotactic radiosurgery (SRS) or develop brain metastases. A prospective, multi-institutional, randomized trial of upfront EGFR-TKI with RT at intracranial progression versus upfront RT followed by EGFR-TKI is urgently needed. Copyright © 2016 Elsevier Inc.

    The objective was to elucidate clinical and imaging features of skeletal involvement, recurrences, and metastases of extraskeletal myxoid chondrosarcoma. Included in this series are 4 patients, aged 44 to 65 years, 3 of whom were men and 1 a woman. The primary lesions were in the thigh (n 3) and the upper arm (n = 1). Three patients with multiple metastases died of the disease, 2 were considered to have local recurrence in the adjacent bone. Skeletal metastases occurred after lung metastases in 2 cases, and before lung metastases in 1 case. Typical imaging findings are well-defined lesions with no sclerotic margin or matrix mineralization. A slow, but persistent growth is noted on the imaging features. Although skeletal metastases of chondrosarcoma of bone and soft tissue are rare, myxoid chondrosarcomas, currently classified tumors of uncertain differentiation, rarely metastasize and/or recur in the bones. The imaging features are typically of a localized lesion with cortical disruption or expansion. (orig.)

    Somatic alterations in cellular DNA underlie almost all human cancers1. The prospect of targeted therapies2 and the development of high-resolution, genome-wide approaches3–8 are now spurring systematic efforts to characterize cancer genomes. Here we report a large-scale project to characterize copy-number alterations in primary lung adenocarcinomas. By analysis of a large collection of tumors (n = 371) using dense single nucleotide polymorphism arrays, we identify a total of 57 significantly recurrent events. We find that 26 of 39 autosomal chromosome arms show consistent large-scale copy-number gain or loss, of which only a handful have been linked to a specific gene. We also identify 31 recurrent focal events, including 24 amplifications and 7 homozygous deletions. Only six of these focal events are currently associated with known mutations in lung carcinomas. The most common event, amplification of chromosome 14q13.3, is found in ~12% of samples. On the basis of genomic and functional analyses, we identify NKX2-1 (NK2 homeobox 1, also called TITF1), which lies in the minimal 14q13.3 amplification interval and encodes a lineage-specific transcription factor, as a novel candidate proto-oncogene involved in a significant fraction of lung adenocarcinomas. More generally, our results indicate that many of the genes that are involved in lung adenocarcinoma remain to be discovered. PMID:17982442

    We wanted to assess the safety and efficacy of performing radiofrequency ablation (RFA) in patients with non-colorectal liver metastases. In this retrospective study, 25 patients with 40 hepatic metastases (M:F = 17:8; mean age, 57 years; tumor size, 0.5-5.0 cm) from a non-colorectal origin (stomach, biliary, breast, pancreas, kidney and skin) were treated with RFA. The RFA procedures were performed using either an internally cooled electrode or a clustered electrode under ultrasound or CT guidance. Contrast-enhanced CT scans were obtained immediately after RFA and follow-up CT scans were performed within three months after ablation and subsequently at least every six months. The intrahepatic disease-free interval was estimated and the overall survival from the time of the initial RFA was analyzed using the Kaplan-Meier method. No intraprocedural deaths occurred, but four major complications developed, including abscesses (n = 3) and pneumothorax (n 1). Technical effectiveness was determined on the initial follow-up images. During the follow-up period (range, 5.9-68.6 months; median time, 18.8 months) for 37 tumors in 22 patients where technical effectiveness was achieved, 12 lesions (32%, 12 of 37) showed local tumor progression and new intrahepatic metastases occurred in 13 patients (59%, 13 of 22). The median intrahepatic disease-free interval was 10.1 months. The 1-year, 3-year and 5-year overall survival rates after RFA were 86%, 39% and 19%, respectively RFA showed intermediate therapeutic effectiveness for the treatment of non-colorectal origin liver metastases.

RESULTS: CA125, carcinoembryonic antigen, and cytokeratins 7 and 20 can distinguish between colonic and serous or endometrioid adenocarcinomas of the ovary in both...... primary and metastatic lesions. Mucinous ovarian adenocarcinomas differed in that they express carcinoembryonic antigen and cytokeratins 7 and 20 and weakly express CA125. The other glycoprotein antigens were equally expressed by ovarian and colonic adenocarcinomas and therefore were of no use...... in distinguishing between these 2 entities. CONCLUSION: A panel of monoclonal antibodies against cytokeratins 7 and 20 antigens, CA125, and carcinoembryonic antigen is useful in differentiating serous and endometrioid adenocarcinomas of the ovary from colonic adenocarcinomas.

    Purpose: This is the first Brazilian study intended to evaluate the response of pain relief with radiotherapy in three different fractionation and the clinical differences in managing pain in patients with painful bone metastases. Methods: Prospective study of patients with painful bone metastases referred to the Radiotherapy Sector of the Hospital de Cancer de Barretos for pain-relieving radiotherapy between March and December 2010. It is known that radiotherapy seems to alter the activation of osteoclast-mediated bone resorption, relieving pain in cases of painful bone metastases. Patients were assessed in relation to the status of pain intensity before and after the initiation of radiotherapy. Either a single fraction of 8Gy, five fractions of 4Gy or ten fractions of 3Gy were given. A visual analog scale (VAS) was applied by doctors, nurses and nursing technicians to assess pain intensity at each session of radiotherapy, and follow-up at 8, 30 and 90 days from the end of treatment. Results: We evaluated 92 consecutive patients, 48 male and 44 female, with a median age of 58 years. We found that 14% of patients referred from the Palliative Care or Clinical Oncology sectors need better pharmacological analgesia due to severe pain, compared with 40.5% of patients from the other sectors (p = 0.004). We also found that the onset of pain relief to patients receiving 10 fractions of 300cGy analgesia without changing the pre-radiotherapy analgesia occurred with significance after the fifth fraction. Improvement in pain experienced within 90 days of follow-up was found in eighty percent of patients, independent of fractionated radiotherapy, site of metastases and the clinical condition of the patient. Discussion/Conclusion: The Palliative Care and Clinical Oncology sectors expressed greater concern in regards to analgesia for the patient with painful bone metastases.

    The HER2 oncogene was recently reported to be amplified and overexpressed in esophageal adenocarcinoma. However, the relationship of HER2 amplification in esophageal adenocarcinoma with prognosis has not been well defined. The scoring systems for clinically evaluating HER2 in esophageal adenocarcinoma are not established. The aims of the study were to establish a HER2 scoring system and comprehensively investigate HER2 amplification and overexpression in esophageal adenocarcinoma and its precursor lesion. Using a tissue microarray, containing 116 cases of esophageal adenocarcinoma, 34 cases of BE, 18 cases of low grade dysplasia and 15 cases of high grade dysplasia, HER2 amplification and overexpression were analyzed by HercepTest and CISH methods. The amplification frequency in an independent series of 116 esophageal adenocarcinoma samples was also analyzed using Affymetrix SNP 6.0 microarrays. In our studies, we have found that HER2 amplification does not associate with poor prognosis in total 232 esophageal adenocarcinoma patients by CISH and high density microarrays. We further confirm the similar frequency of HER2 amplification by CISH (18.10%; 21/116) and SNP 6.0 microarrays (16.4%, 19/116) in esophageal adenocarcinoma. HER2 protein overexpression was observed in 12.1 % (14/116) of esophageal adenocarcinoma and 6.67% (1/15) of HGD. No HER2 amplification or overexpression was identified in BE or LGD. All HER2 protein overexpression cases showed HER2 gene amplification. Gene amplification was found to be more frequent by CISH than protein overexpression in esophageal adenocarcinoma (18.10% vs 12.9%). A modified two-step model for esophageal adenocarcinoma HER-2 testing is recommend for clinical esophageal adenocarcinoma HER-2 trial. PMID:21460800

    Full Text Available The pituitary gland and infundibulum can be involved in a variety of medical conditions, including infiltrative diseases, fungal infections, tuberculosis, and primary and metastatic tumors. Metastases to the pituitary gland are absolutely rare, and they are generally secondary to pulmonary carcinoma in men and breast carcinoma in women. Pituitary metastases more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The posterior lobe involvement may explain why patients with pituitary metastases frequently present with diabetes insipidus. We are presenting a case report of a 78-year-old male patient who had metastatic prostate with sudden onset of polyuria and persistent thirst. He had no electrolyte imbalance except mild hypernatremia. The MRI scan of the brain yielded a suspicious area in pituitary gland. A pituitary stalk metastasis was found on magnetic resonance imaging (MRI of pituitary. Water deprivation test was compatible with DI. A clinical response to nasal vasopressin was achieved and laboratory results revealed central diabetes insipidus. As a result, the intrasellar and suprasellar masses decreased in size, and urinary output accordingly decreased.

  6. Are metastases from metastases clinical relevant? Computer modelling of cancer spread in a case of hepatocellular carcinoma.

    Directory of Open Access Journals (Sweden)

    Anja Bethge

    Full Text Available BACKGROUND: Metastasis formation remains an enigmatic process and one of the main questions recently asked is whether metastases are able to generate further metastases. Different models have been proposed to answer this question; however, their clinical significance remains unclear. Therefore a computer model was developed that permits comparison of the different models quantitatively with clinical data and that additionally predicts the outcome of treatment interventions. METHODS: The computer model is based on discrete events simulation approach. On the basis of a case from an untreated patient with hepatocellular carcinoma and its multiple metastases in the liver, it was evaluated whether metastases are able to metastasise and in particular if late disseminated tumour cells are still capable to form metastases. Additionally, the resection of the primary tumour was simulated. The simulation results were compared with clinical data. RESULTS: The simulation results reveal that the number of metastases varies significantly between scenarios where metastases metastasise and scenarios where they do not. In contrast, the total tumour mass is nearly unaffected by the two different modes of metastasis formation. Furthermore, the results provide evidence that metastasis formation is an early event and that late disseminated tumour cells are still capable of forming metastases. Simulations also allow estimating how the resection of the primary tumour delays the patient's death. CONCLUSION: The simulation results indicate that for this particular case of a hepatocellular carcinoma late metastases, i.e., metastases from metastases, are irrelevant in terms of total tumour mass. Hence metastases seeded from metastases are clinically irrelevant in our model system. Only the first metastases seeded from the primary tumour contribute significantly to the tumour burden and thus cause the patient's death.

    BACKGROUND: Obesity is associated with an increased incidence of oesophageal and oesophagogastric junction adenocarcinoma, in particular Siewert types I and II. This study compared abdominal fat composition in patients with oesophageal\\/junctional adenocarcinoma with that in patients with oesophageal squamous cell carcinoma and gastric adenocarcinoma, and in controls. METHOD: In total, 194 patients (110 with oesophageal\\/junctional adenocarcinoma, 38 with gastric adenocarcinoma and 46 with oesophageal squamous cell carcinoma) and 90 matched control subjects were recruited. The abdominal fat area was assessed using computed tomography (CT), and the total fat area (TFA), visceral fat area (VFA) and subcutaneous fat area (SFA) were calculated. RESULTS: Patients with oesophageal\\/junctional adenocarcinoma had significantly higher TFA and VFA values compared with controls (both P < 0.001), patients with gastric adenocarcinoma (P = 0.013 and P = 0.006 respectively) and patients with oesophageal squamous cell carcinoma (both P < 0.001). For junctional tumours, the highest TFA and VFA values were seen in patients with Siewert type I tumours (respectively P = 0.041 and P = 0.033 versus type III; P = 0.332 and P = 0.152 versus type II). CONCLUSION: Patients with oesophageal\\/junctional adenocarcinoma, in particular oesophageal and Siewert type I junctional tumours, have greater CT-defined visceral adiposity than patients with gastric adenocarcinoma or oesophageal squamous cell carcinoma, or controls.

    Cancer prevalence is estimated at around 2% of the population and on average between 64-80% of patients with solid tumors develop bone metastases, being breast tumors, lung and prostate those who do more frequency. In this paper an estimate of the prevalence of bone pain from metastases, with reference to the data reported in the literature is presented. the different treatment techniques are summarized for pain management with special emphasis on Radionuclidic therapy, analyzing the different factors to consider for the selection of suitable radiopharmaceutical. cost data and cost-benefit of some radiopharmaceuticals for the purpose to take into account during their selection are provided. It is concluded that although the treatment of metastatic bone disease requires multidisciplinary therapies, Radionuclidic therapy is not sufficiently used, particularly by inadequate perception of risks and costs of radiopharmaceuticals, despite the undeniable support of its efficacy and tolerability.

    Purpose: To retrospectively investigate the effectiveness of linear accelerator based radiosurgery (RS) in the treatment of brain metastases (BM). Material and methods: Of 55 patients with a total of 72 BM, 41 patients had a single brain metastasis and 14 patients had two or three metastases. Median tumour dose of 15 Gy (range 8-20 Gy) was prescribed to a median isodose surface of 90% (range 70-100%) encompassing the target volume. Results: The median survival time (MST) for all 55 patients was 7 months [95% confidence interval (CI), 5-10 months] and 2-year survival is 18%. There was no significant difference between patients who had one brain metastasis and those with either two or three metastases (log rank P=0.7565). Multivariate analysis in patients with a single BM showed that interval between primary diagnosis (PD) to BM, maximum size of metastasis, and histology (renal cell carcinoma and melanoma versus others) were independent prognostic factors influencing survival. Local control was obtained in 66/72 (92%) metastases. Actuarial local control at 24 months was 52%. Only age (≤50 years vs >50 years) and histology (renal cell versus others) influenced local control in the univariate analysis in patients with a single BM. In multivariate analysis, size, histology (renal cell and melanoma versus others), activity of extracranial metastatic disease, age, interval from PD to BM and location (midline versus other) independently influenced local control, while the dose was not significant for our patient group. Only one patient developed radiographically suspected RS-induced necrosis after previous whole brain RT. Conclusion: RS was effective and little toxic in BM. Identification of prognostic factors must be performed to gain knowledge on patients most likely to benefit from this procedure

    The aim of the present study was to analyse magnetic resonance findings of intramuscular metastases (IM) in a relatively large series. From January 2000 to January 2010, 28 patients (207 metastases) were retrospectively identified in the radiological database of the Martin-Luther-University. Several different scanning protocols were used depending on the localisation of IM. In 12 patients diffusion-weighted (DW) images were obtained with a multi-shot SE-EPI sequence. Apparent diffusion coefficient (ADC) maps were also calculated. Furthermore, fusion images were manually generated between the DW and half-Fourier acquisition single-shot turbo spin echo (HASTE) images. On T2-weighted images, 97% of the recognised IM were hyperintense in comparison to unaffected musculature, and 3% were mixed iso- to hyperintense. On T1-weighted images most IM (91%) were homogeneously isointense in comparison to muscle tissue, whereas 4% were hypointense, and 5% lightly hyperintense. ADC maps were calculated for 91 metastases ranging from 0.99 to 4.00 mm 2 s -1 (mean value 1.99 ± 0.66). ADC values of low ( 3.0) in 6%. Of the IM that were investigated with contrast medium, 88.5% showed marked enhancement. It was homogeneous in 88% and heterogenous in 6%. Rim enhancement with central low attenuation was seen in 6%. There was no difference in enhancement characteristics with respect to ADC values or fusion patterns. Peritumoral enhancement was identified in 2.4%. Magnetic resonance features of muscle metastases are relatively typical and consist of round or oval intramuscular masses with well-defined margins, marked enhancement, low or moderate ADC values, and moderate to high signal intensity on fusion images.

    Operative treatment offers the best chance for long term survival in lung cancer of early stage. In the same way surgery may be the most efficient treatment of lung metastases from tumors of extrapulmonary site. The preoperative investigations have to prove that in case of lung cancer this is restricted to one hemithorax and in lung metastases that these are restricted to the lungs exclusively. They also have to prove that the lung function allows adequate resection. This is mainly lobectomy and pneumonectomy, sometimes sleeve resection and rarely segmentectomy for primary lung cancers. Resection of metastases preferably is by wedge excision or enucleation. In bilateral lesions median sternotomy is the favoured approach to both lungs in a single session. Long term results in primary lung cancer depend on the tumor stage. As a rule of thumb by each step of tumor stage the 5-year-survival rate is cut to half. In regard to histology small cell undifferentiated carcinomas are considered surgical indications only in the very early stage and need to be treated by adjuvant chemotherapy. The operative mortality is correlated to the extent of resection and by average is higher for primary carcinoma of the lung because of the usually higher age level and additional pulmonary damage. Patients operated for pulmonary metastases, however, are in lower age range and due to less functional risks, the operative mortality in most series is between 0 and 3%. Early detection of lung cancer, i.e., immediate and expert exploration of suspicious X-ray findings or respiratory symptoms particularly in smokers and with asbestos exposed individuals will contribute to an increasing efficacy of surgical treatment.

    At time of diagnosis, 10 to 25% of patients with colorectal cancer present synchronous liver metastases. The treatment of such patients remains controversial without any evidence based organization. Therapeutic sequences are discussed including chemotherapy, colorectal surgery, liver resection and even radio-chemotherapy for some rectal cancers. In case of resectable liver metastases, preoperative chemotherapy offers the advantage of earlier treatment of micro-metastases as well as evaluation of tumor responsiveness, which can help shape future therapy. In this setting, different surgical strategies can be chosen (classical staged procedures with colorectal surgery followed by liver surgery, simultaneous resections or liver first approach) depending on the importance of the primary and metastatic tumors. The literature remains limited, but the results of these strategies seem identical in term of postoperative morbidity and long-term survival. Staged procedures are preferred in case of major liver resection. Location of the primary tumor on the low or mid rectum will necessitate preoperative long course chemoradiotherapy and a more complex multidisciplinary organization. For patients with extensive liver metastases, non-resectability must be assessed by experienced surgeon and radiologist before treatment and during chemotherapy. In this group of patients, improved chemotherapy regimen associated with targeted therapies and new surgical strategies (portal vein embolization, ablation, staged hepatectomies…) have improved resection rate (15 to 30-40%) and long-term survival. Treatment organization for the primary tumor remains controversial. Resection of the primary to manage symptoms such as obstruction, perforation or bleeding is advocated. For patients with asymptomatic primary a non-surgical approach permits to begin rapidly chemotherapy and obtain a better control of the disease. On the other hand, initial resection of the primary may avoid complications and

    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.

    Percutaneous radiotherapy is the most effective modality for treatment of metastatic bone cancer. Local irradiation improves overall quality of life by relieving pain in most patients. It also helps preventing complications as pathological fractures in lytic bone lesions by new bone formation. In a retrospective study on 100 patients, irradiated for lytic bone metastases, the radiotherapeutic effect on alleviation of pain and on recalcification rate was investigated. In our experience in 84% of the cases pain and disability associated with bone metastases could be decreased. 38% of the patients had complete relief of symptoms. A correlation between subjective therapy effect and histology of the primary tumor was not demonstrated. Remineralization was found in 67% of all irradiated skeletal areas (n=137) (recalcification rate in breast cancer 77%, in bronchial carcinoma 27%, and in renal cell carcinoma 25%). After a total dose of 30 Gy reduction of the metastases-associated pain was achieved in 81% of the cases and remineralization was observed in 70% of the cases. (orig.) [de

    The liver is the most common site for colorectal cancer (CRC) metastases. Radioembolization with yttrium-90 (Y90) represents an alternative approach in the management of unresectable hepatic colorectal metastases. The objective of this study was to evaluate outcomes after treatment with Y90. A retrospective review of patients undergoing Y90 glass microsphere treatment for metastatic CRC from 2009 to 2013 was conducted. Multivariable analysis (MVA) of factors related to overall survival (OS) was performed using the Cox proportional hazard and OS estimates were calculated using the Kaplan-Meier method. We identified 68 patients. Median and 2-year OS were 11.6 months and 34%. For patients with ≤ 25% hepatic burden of disease (HBD) and 1 chemotherapy regimen, 2-year OS was 63%. Median and 2-year OS for patients with ≤ 25% versus > 25% HBD were 19.6 months and 42% versus 3.4 months and 0% (P 25% HBD, ≥ 3 lines of chemotherapy, and higher CEA were independently prognostic for increased mortality, and resected status of the primary tumor was associated with decreased mortality. The presence of extrahepatic metastases was not prognostic. Toxicities were mild and only 5 patients experienced Grade 3/4 biochemical toxicity. Yttrium-90 was associated with acceptable OS with minimal morbidity in this series. Minimal exposure to chemotherapy and low HBD were found to be associated with better OS, however, even patients with chemotherapy-refractory disease received a benefit from treatment.

    Full Text Available Abstract Background Malignant Mesothelioma is a rare primary neoplasm affecting the serosal membranes. During its relative short course, this malignant neoplasm can give local and, rarely, distant haematogenous metastases in different organs. The reported metastatic sites include liver, lung, heart, brain, thyroid, adrenals, kidneys, pancreas, bone, soft tissue, skin and lymph nodes. Case Presentation We report a sixty one year-old man with a history of malignant pleural epithelioid mesothelioma treated with six cycles of Pemetrexed and Carboplatin completed 03/11/04 followed by radiotherapy to the drain site 250 Kv/TD20Gy/5F completed 13/12/2004. Then he developed multiple facial skin lesions 4 years later. These lesions were proved to be metastatic malignant sarcomatoid mesothelioma. Conclusion Mesothelioma metastases should be suspected in any known Mesothelioma patient with newly developed skin lesion.

    Purpose: To determine the role of adjuvant postoperative radiotherapy (RT) following radical prostatectomy (RP) in a group of patients with pathologic Stage T3/4 adenocarcinoma of the prostate followed for a median of 10 years after treatment. Methods and Materials: Between 1970 and 1983, 159 patients underwent RP for newly diagnosed adenocarcinoma of the prostate and were found to have pathologic Stage T3/4 tumors. Forty-six received adjuvant RT and 113 did not. Radiotherapy usually consisted of 45-50 Gy to the whole pelvis followed by a boost to the prostate bed of 10-15 Gy, to a total dose of 55-65 Gy. Patients were analyzed with respect to survival, disease-free survival, local control, and freedom from distant metastases. A rising prostate-specific antigen in the absence of other evidence of relapse was scored as a separate category of recurrence. Results: Both groups of patients have been followed for a median of 10 years. The actuarial survival at 10 and 15 years was 62% and 62% for the RT group compared to 52% and 37%, respectively, for the RP group (p = 0.18). The disease-free survival for the RT group was 55% and 48% at 10 and 15 years, respectively, compared to 37% and 33% for the RP group (p = 0.16). Similarly, there was no difference in the rate of distant metastases between the two groups. In contrast, the local relapse rate was significantly reduced by the addition of postoperative radiotherapy. The actuarial local control rate at 10 and 15 years was 92% and 82%, respectively, for the RT group vs. 60% and 53% for the RP group (p 0.002). Conclusions: While postoperative pelvic RT significantly improves local control compared to RP alone for pathologic Stage T3/4 prostate cancer, it has no impact on distant metastases and consequently does not improve survival. These data are consistent with the conclusion that many patients with pathologic Stage T3/4 prostate cancer have occult metastases at presentation and will not be cured by local therapies alone

    Full text: Tumor hypoxia, particularly in anemia, increases the risk of distant metastases and decreases survival. However, the benefits of stimulating erythropoiesis to supraphysiological levels are unclear. This study examines the effect of darbepoetin alfa (DEPA) on tumor oxygenation and the response to therapeutic radiation (XRT) in rats with initially normal hematocrit. R3230 adenocarcinoma was transplanted into the flank of female Fisher 344 rats. Starting on Day 4 post transplant, the rats received DEPA 3 μg/kg or normal saline sc tiw. At 3 weeks post transplant, pO2 was measured and the tumor excised, or the tumor was irradiated. pO2 was determined using an optical microprobe. In histologic studies, rats were injected with pimonidazole prior to sacrifice, and the tumors excised and stained with an antibody to pimonidazole (PIMO). Extent/intensity of staining was assessed by 3 observers and averaged to yield an IHC score. Rats ± DEPA with tumors 7 -12mm diameter were randomised to receive 32 Gy in 4 bid doses or sham irradiation. Tumor diameters in the 4 groups (±DEPA x ±XRT, total n=41) were measured by calipers. Failure was defined by the tumor reaching 15mm in diameter and used to generate Kaplan-Meier curves. Hematocrit at transplant averaged 45% (n=104) versus 67% in the DEPA-treated rats (n=18, p<0.0001) and 44% in the control animals (n=21.) Median pO2 in the DEPA-treated rats vs. controls did not differ significantly (17 vs. 13 mm Hg, p=0.10.) However, the fraction of tumor pO2 measurements <10mm Hg in the DEPA-treated rats was lower (21% vs. 37%, p=0.046.) IHC score was also less in the DEPA group (p=0.03.) XRT significantly improved failure-free survival (p<0.0001.) While the addition of DEPA to either the XRT or control groups did not significantly increase survival, the trend in both cases favored the DEPA-treated groups. In this tumor, treatment with DEPA improves oxygenation. However, no significant enhancement in radioesponsiveness by DEPA

    Polycystic disease is defined as a heritable disorder with diffuse involvement of both kidneys. The term 'Polycystic disease' comprises at least two separate, genetically different disease-one with an onset typically in childhood (infantile polycystic disease) and the other with an onset typically in adulthood (adult polycystic disease). Adult polycystic kidney disease is the most common form of cystic kidney disease in humans. Ultrasonography is a very useful noninvasive diagnostic modality in the patient with clinically suspected renal diseases as well as screening test. 14 cases of ultrasonography in patient with polycystic kidney were reviewed. All cases show unilateral or bilateral enlarged kidneys. 7 cases reveal kidneys and liver replaced by multiple cysts of varing size. Screening ultrasonography for a familial tree is reported

    Primary carcinoma of the vermiform appendix is a rare disease with few clinical symptoms. Accordingly, preoperative diagnosis of appendiceal cancer is challenging because of the lack of specific symptoms. We herein report a case of appendicular adenocarcinoma found unexpectedly during laparoscopic surgery in a 69-year-old Japanese female patient diagnosed with serous papillary adenocarcinoma, in order to determine whether optimal cytoreduction could successfully be achieved at the time of primary surgery. We performed diagnostic laparoscopic surgery in order to make a correct diagnosis based on the histological tissue. The vermiform appendix was found to contain a tumor measuring 1.5 cm wide and 4.5 cm long. Laparoscopic appendectomy, partial omentectomy, and partial resection of the lesion in the peritoneum were performed. The histological diagnosis was mucinous adenocarcinoma of the vermiform appendix, and the stage was T4NxM1. The patient received adjuvant chemotherapy with mFOLFOX 6 (5FU, leucovorin, and oxaliplatin). She achieved stable disease and was alive with disease eleven months after surgery. We therefore recommend that gynecologists should not rule out the possibility of appendiceal cancer, even in cases with preoperative findings similar to those of serous papillary adenocarcinoma of the peritoneum with peritoneal disseminated tumors.

    DNA methylation and histone modifications determine renal programming and the development and progression of renal disease. The identification of the way in which the renal cell epigenome is altered by environmental modifiers driving the onset and progression of renal diseases has extended our understanding of the pathophysiology of kidney disease progression. In this review, we focus on current knowledge concerning the implications of epigenetic modifications during renal disease from early development to chronic kidney disease progression including renal fibrosis, diabetic nephropathy and the translational potential of identifying new biomarkers and treatments for the prevention and therapy of chronic kidney disease and end-stage kidney disease.

    Full Text Available Renal paraneoplastic vasculitis (RNPV is rare. It can be revealed by glomerulonephritis, microaneurysms or renal failure. RPNV may precede the onset of the primary tumor, and treatment and prognosis depend on the etiology (primary tumor. A 54-year-old man who had a primary lung adenocarcinoma was admitted for nephrotic syndrome. The investigations revealed RNPV. The patient was treated with corticosteroids at high dose and cyclophosphamide with improvement of the renal condition; however, the patient died from worsening of his pulmonary neoplasia.

    Thirty-six patients were given intraoperative radiotherapy for adenocarcinoma of the pancreas between April 1980 and March 1986. Twenty-six of those with well-advanced cancer underwent palliative intraoperative radiotherapy of their main primary lesions (1,500 to 3,000 rads). Fourteen of the 19 patients in this group who had intractable back pain before surgery achieved relief within one week after treatment. Of the remaining 10 patients who underwent pancreatectomy and received adjuvant intraoperative radiotherapy (2,000 to 3,000 rads), two remain clinically free of disease five years and six months and four years and six months after palliative distal pancreatectomy.

    Identifying patient-related factors as well as symptoms and signs that can predict pancreatic cancer at a resectable stage, which could be used in an attempt to identify patients at an early stage of pancreatic cancer that would be appropriate for surgical resection and those at an unresectable stage be sparred unnecessary surgery. A retrospective chart review was conducted at a major tertiary care, university hospital in Riyadh, Saudi Arabia. The study population included individuals who underwent a computed tomography and a pancreatic mass was reported as well as the endoscopic reporting database of endoscopic procedures where the indication was a pancreatic mass, between April 1996 and April 2012. Any patient with a histologically confirmed diagnosis of adenocarcinoma of the pancreas was included in the analysis. We included patients' demographic information (age, gender), height, weight, body mass index, historical data (smoking, comorbidities), symptoms (abdominal pain and its duration, anorexia and its duration, weight loss and its amount, and over what duration, vomiting, abdominal distention, itching and its duration, change in bowel movements, change in urine color), jaundice and its duration. Other variables were also collected including laboratory values, location of the mass, the investigation undertaken, and the stage of the tumor. A total of 61 patients were included, the mean age was 61.2 ± 1.51 years, 25 (41%) were females. The tumors were located in the head (83.6%), body (10.9%), tail (1.8%), and in multiple locations (3.6%) of the pancreas. Half of the patients (50%) had Stage IV, 16.7% stages IIB and III, and only 8.3% were stages IB and IIA. On univariable analysis a lower hemoglobin level predicted resectability odds ratio 0.65 (95% confidence interval, 0.42-0.98), whereas on multivariable regression none of the variables included in the model could predict resectability of pancreatic cancer.

    The kidneys of patients with chronic renal failure undergoing maintenance hemodialysis may show different variances or complications. Most common are secondarily acquired renal cysts, which my be found in as many as 92% of patients after 8 years of hemodialysis. Single (in 12.5% of patients) or multiple (8.3%) cysts with bleeding are common; additionally, hematuria or ruptured cysts may be found. Bleeding into cysts is more common in patients with autosomal dominant polycystic kidney disease. Due to the decreasing urinary production development of kidney stones is very uncommon, but calcification in or around cysts can be found in 71% of patients. Kidney tumors occur 41 times more often in patients with chronic renal failure than in patients without kidney disease. We detected tumors in 4.2% of our patients on long-term dialysis. Diagnostic differentiation of the relatively slow growing and fairly late metastasizing malignant tumors from adenomas is not possible. Nevertheless, we screen our patients every 3-4 years. Computed tomography is superior to ultrasonography for this purpose, because ultrasonography lacks the necessary sensitivity in this group of patients. (orig.) [de

    Full Text Available Synchronous gynecological cancers are rarely described. Those cases account for approximately up to 6% of female genital tract malignancies. The presence of synchronous endometrial adenocarcinoma and gynecological tract neoplasia is rare – the most commonly described is synchronous adenocarcinoma and endometrial ovarian cancer (accounting for 15-20% of ovarian neoplasia and 5% of endometrial cancers. Concomitant uterine carcinosarcoma and ovarian cancer, or endometrial adenocarcinoma are extremely rare. Up till now, only 3 cases of synchronous adenocarcinoma and leiomyosarcoma were described. In the present study a case of 60-year-old woman diagnosed with synchronous endometrial adenocarcinoma and leiomyosarcoma uteri is described. As the preoperative evaluation revealed endometrial adenocarcinoma G2 with intermediate-risk of lymph node metastasis and synchronous leiomyosarcoma G3, total hysterectomy with bilateral salpingo-oophorectomy and systemic lymphadenectomy was performed showing no lymphatic involvement. In the postoperative evaluation the patient was qualified to adenocarcinoma low recurrence-risk group (adenocarcinoma G1 with no LVSI, FIGO IA – no further radiotherapy was required. However, as synchronous leiomyosarcoma G3 was diagnosed, we decided to refer the patient for adjuvant chemotherapy. Contemporary recommendation on the diagnosis and treatment of uterine carcinomas, especially uterine leiomyosarcomas, is also described in this paper. The presented case showed that diagnosis and treatment of women with uterine tumors should be individualized as in the same case an extremely rare cancer type can be present which, consequently, changes the treatment regimen and prognosis.

    Purpose: The goal of this study was to evaluate dosimetric parameters, acute toxicity, pathologic response, and local control in patients treated with preoperative intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy for localized gastric adenocarcinoma. Methods: Between November 2007 and April 2010, 25 patients with localized gastric adenocarcinoma were treated with induction chemotherapy, followed by preoperative IMRT and concurrent chemotherapy and, finally, surgical resection. The median radiation therapy dose was 45 Gy. Concurrent chemotherapy was 5-fluorouracil and oxaliplatin in 18 patients, capecitabine in 3, and other regimens in 4. Subsequently, resection was performed with total gastrectomy in 13 patients, subtotal gastrectomy in 7, and other surgeries in 5. Results: Target coverage, expressed as the ratio of the minimum dose received by 99% of the planning target volume to the prescribed dose, was a median of 0.97 (range, 0.92-1.01). The median V{sub 30} (percentage of volume receiving at least 30 Gy) for the liver was 26%; the median V{sub 20} (percentage of volume receiving at least 20 Gy) for the right and left kidneys was 14% and 24%, respectively; and the median V{sub 40} (percentage of volume receiving at least 40 Gy) for the heart was 18%. Grade 3 acute toxicity developed in 14 patients (56%), including dehydration in 10, nausea in 8, and anorexia in 5. Grade 4 acute toxicity did not develop in any patient. There were no significant differences in the rates of acute toxicity, hospitalization, or feeding tube use in comparison to those in a group of 50 patients treated with preoperative three-dimensional conformal radiation therapy with concurrent chemotherapy. R0 resection was obtained in 20 patients (80%), and pathologic complete response occurred in 5 (20%). Conclusions: Preoperative IMRT for gastric adenocarcinoma was well tolerated, accomplished excellent target coverage and normal structure sparing, and led to appropriate

    Ten patients with brain metastases from lung cancer treated by irradiation between 1982 and 1985 were reviewed. Neurologic improvement by irradiation was obtained in all patients. The median duration of neurologic function control by irradiation and the median survival from the diagnosis of brain metastases were 9 months and 11 months, respectively. General performance status, neurologic function class and the presence or absence of other sites of metastases were important prognostic factors for survival. More than 50 Gy brain irradiation except small cell carcinoma was thought to be necessary to control the brain metastases. CT examinations were useful but limited to evaluate the effectiveness of irradiation. (author)

    Full Text Available Primary signet cell cancer of the urinary bladder is a relatively rare entity. Since there is no mucinous epithelium in the bladder, It is proposed that the tumor arises from metaplastic urothelium. Two thirds of the tumours are mucin secreting, in most of which the site of the deposition is either extracellular or intracellular displacing the nucleus to a peripheral crescent, giving the cells a signet ring appearance. The tumours are most often infiltrative and diffusely involving the majority of the bladder akin to its name sake in stomach. It is essential to distinguish this carcinoma from gastrointestinal metastases as different therapeutic strategies are often necessary.

    Full Text Available The search of molecular markers of metastasing and prognosis in prostate cancer remains an urgent task. In this study, we investigated the relationship of gene expression heparanase-1 (HPSE1 and D-glucuronil C5-epimerase (GLCE with early disease relapse and metastasis of a 2,5−3 years after diagnosis. It was shown that the ratio of the expression levels of genes HPSE1/GLCE > 1 may serve as a prognostic relapse marker and trends of the tumour to metastasis. The data obtained suggest to use this option as a molecular marker for the diagnostics of metastatic process and the disease prognosis.

    K-ras codon 12 point mutations mRb and p53 gene deletions were examined in tissues from 120 normal lungs and lung adenocarcinomas that were Formalin-treated and paraffin-embedded 25 years ago. The results showed that 12 of 60 (20%) lung adenocarcinomas had mRb deletions. All lung adenocarcinomas that were initially found bearing deleted mRb had p53 deletions (15 of 15; 100%). A significantly higher mutation frequency for K-ras codon 12 point mutations was also found in the lung adenocarcinomas from mice exposed to 24 once-weekly neutron irradiation (10 of 10; 100%) compared with those exposed to 24 or 60 once-weekly γ-ray doses (5 of 10; 50%). The data suggested that p53 and K-ras gene alterations were two contributory factors responsible for the increased incidence of lung adenocarcinoma in B6CF 1 male mice exposed to protracted neutron radiation

    Full Text Available Primary adenocarcinoma of the urinary bladder is a rare disease. It occurs in 0.5-2% of all bladder cancers and is discussed as the malignant counterpart of nephrogenic adenomas. We report a 46-year-old white female presented with gross hematuria for clinical examination. Histopathology revealed pT2, Pn1, L1, G2 adenocarcinoma of the bladder and carcinoma in situ according to the TNM classification. Computed tomography scan diagnostic was unremarkable. Patients with adenocarcinoma of the urinary bladder should be treated vigorously and without time delay. Only 7 cases of adenocarcinoma in the urinary bladder (mesonephroid have been described until now. We present a case of clear cell adenocarcinoma of the urinary bladder, mesonephroid type that early diagnosed and till now 3 months after the cystectomy without symptoms and without complications.

    Metastatic progression due to development or enrichment of therapy-resistant tumor cells is eventually lethal. Molecular characterization of such chemotherapy resistant tumor cell clones may identify markers responsible for malignant progression and potential targets for new treatment. Here, in a case of stage IV adenocarcinoma of the gastroesophageal junction, we report the successful genome wide analysis using array comparative genomic hybridization (CGH) of DNA from only fourteen tumor cells using a bead-based single cell selection method from a bone metastasis progressing during chemotherapy. In a case of metastatic adenocarcinoma of the gastroesophageal junction, the progression of bone metastasis was observed during a chemotherapy regimen of epirubicin, oxaliplatin and capecitabine, whereas lung-, liver and lymph node metastases as well as the primary tumor were regressing. A bone marrow aspirate sampled at the site of progressing metastasis in the right iliac bone was performed, and single cell molecular analysis using array-CGH of Epithelial Specific Antigen (ESA)-positive metastatic cells, and revealed two distinct regions of amplification, 12p12.1 and 17q12-q21.2 amplicons, containing the KRAS (12p) and ERBB2 (HER2/NEU) (17q) oncogenes. Further intrapatient tumor heterogeneity of these highlighted gene copy number changes was analyzed by fluorescence in situ hybridization (FISH) in all available primary and metastatic tumor biopsies, and ErbB2 protein expression was investigated by immunohistochemistry. ERBB2 was heterogeneously amplified by FISH analysis in the primary tumor, as well as liver and bone metastasis, but homogenously amplified in biopsy specimens from a progressing bone metastasis after three initial cycles of chemotherapy, indicating a possible enrichment of erbB2 positive tumor cells in the progressing bone marrow metastasis during chemotherapy. A similar amplification profile was detected for wild-type KRAS, although more heterogeneously

    Purpose: To evaluate the efficacy of adjuvant chemoradiation therapy (CRT) for pancreatic adenocarcinoma patients ≥75 years of age. Methods: The study group of 655 patients underwent pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma at the Johns Hopkins Hospital over a 12-year period (8/30/1993 to 2/28/2005). Demographic characteristics, comorbidities, intraoperative data, pathology data, and patient outcomes were collected and analyzed by adjuvant treatment status and age ≥75 years. Cox proportional hazards analysis determined clinical predictors of mortality and morbidity. Results: We identified 166 of 655 (25.3%) patients were ≥75 years of age and 489 of 655 patients (74.7%) were <75 years of age. Forty-nine patients in the elderly group (29.5%) received adjuvant CRT. For elderly patients, node-positive metastases (p = 0.008), poor/anaplastic differentiation (p = 0.012), and undergoing a total pancreatectomy (p = 0.010) predicted poor survival. The 2-year survival for elderly patients receiving adjuvant therapy was improved compared with surgery alone (49.0% vs. 31.6%, p = 0.013); however, 5-year survival was similar (11.7% vs. 19.8%, respectively, p = 0.310). After adjusting for major confounders, adjuvant therapy in elderly patients had a protective effect with respect to 2-year survival (relative risk [RR] 0.58, p = 0.044), but not 5-year survival (RR 0.80, p = 0.258). Among the nonelderly, CRT was significantly associated with 2-year survival (RR 0.60, p < 0.001) and 5-year survival (RR 0.69, p < 0.001), after adjusting for confounders. Conclusions: Adjuvant therapy after PD is significantly associated with increased 2-year but not 5-year survival in elderly patients. Additional studies are needed to select which elderly patients are likely to benefit from adjuvant CRT.

  8. Recurrent Barrett's esophagus and adenocarcinoma after esophagectomy

    2004-08-01

    Full Text Available Abstract Background Esophagectomy is considered the gold standard for the treatment of high-grade dysplasia in Barrett's esophagus (BE and for noninvasive adenocarcinoma (ACA of the distal esophagus. If all of the metaplastic epithelium is removed, the patient is considered "cured". Despite this, BE has been reported in patients who have previously undergone esophagectomy. It is often debated whether this is "new" BE or the result of an esophagectomy that did not include a sufficiently proximal margin. Our aim was to determine if BE recurred in esophagectomy patients where the entire segment of BE had been removed. Methods Records were searched for patients who had undergone esophagectomy for cure at our institution. Records were reviewed for surgical, endoscopic, and histopathologic findings. The patients in whom we have endoscopic follow-up are the subjects of this report. Results Since 1995, 45 patients have undergone esophagectomy for cure for Barrett's dysplasia or localized ACA. Thirty-six of these 45 patients underwent endoscopy after surgery including 8/45 patients (18% with recurrent Barrett's metaplasia or neoplasia after curative resection. Conclusion Recurrent Barrett's esophagus or adenocarcinoma after esophagectomy was common in our patients who underwent at least one endoscopy after surgery. This appears to represent the development of metachronous disease after complete resection of esophageal disease. Half of these patients have required subsequent treatment thus far, either repeat surgery or photodynamic therapy. These results support the use of endoscopic surveillance in patients who have undergone "curative" esophagectomy for Barrett's dysplasia or localized cancer.

    2008-07-01

    Recently, p-[{sup 123}I]iodo-L-phenylalanine (IPA) was clinically validated for brain tumour imaging. Preclinical studies demonstrated uptake of IPA into pancreatic adenocarcinoma suggesting its diagnostic application in patients with pancreatic tumours. The aim was to study the tumour uptake of IPA in patients with pancreatic adenocarcinoma and to analyse its biodistribution and dosimetry to assess the radiation dose resulting from its diagnostic use. Patients, methods: Seven patients with pancreatic adenocarcinoma underwent whole-body scintigraphies and SPECT up to 24 h after administration of 250 MBq of IPA. Tumour uptake of IPA was assessed visually. Time activity curves and the corresponding residence times were determined for whole-body, kidneys, liver, spleen, lung, heart content, brain, and testes. Mean absorbed doses for various organs and the effective dose were assessed based on the MIRD formalism using OLINDA/EXM. Results: IPA exhibited no accumulation in proven manifestations of pancreatic adenocarcinomas. IPA was exclusively eliminated by the urine and showed a delayed clearance from blood. Residence times were 0.26 {+-} 0.09 h for kidneys, 0.38 {+-} 0.19 h for liver, 0.15 {+-} 0.07 h for spleen, 0.51 {+-} 0.20 h for lungs, 0.22 {+-} 0.07 h for heart content, 0.11 {+-} 0.05 h for brain, 0.014 {+-} 0.005 h for testes and 6.4 {+-} 2.2 h for the remainder. The highest absorbed doses were determined in the urinary bladder wall and in the kidneys. According to the ICRP 60 the effective dose resulting from 250 MBq IPA was 3.6 {+-} 0.7 mSv. Conclusion: Para-[{sup 123}I]iodo-L-phenylalanine can be used in diagnostic nuclear medicine with acceptable radiation doses. Besides its proven validity for brain tumour imaging, IPA does not appear to be suitable as tracer for pancreatic cancer. (orig.)

    2018-01-01

    This statement was developed to promote international consensus on the definition of borderline resectable pancreatic ductal adenocarcinoma (BR-PDAC) which was adopted by the National Comprehensive Cancer Network (NCCN) in 2006, but which has changed yearly and become more complicated. Based on a symposium held during the 20th meeting of the International Association of Pancreatology (IAP) in Sendai, Japan, in 2016, the presenters sought consensus on issues related to BR-PDAC. We defined patients with BR-PDAC according to the three distinct dimensions: anatomical (A), biological (B), and conditional (C). Anatomic factors include tumor contact with the superior mesenteric artery and/or celiac artery of less than 180° without showing stenosis or deformity, tumor contact with the common hepatic artery without showing tumor contact with the proper hepatic artery and/or celiac artery, and tumor contact with the superior mesenteric vein and/or portal vein including bilateral narrowing or occlusion without extending beyond the inferior border of the duodenum. Biological factors include potentially resectable disease based on anatomic criteria but with clinical findings suspicious for (but unproven) distant metastases or regional lymph nodes metastases diagnosed by biopsy or positron emission tomography-computed tomography. This also includes a serum carbohydrate antigen (CA) 19-9 level more than 500 units/ml. Conditional factors include the patients with potentially resectable disease based on anatomic and biologic criteria and with Eastern Cooperative Oncology Group (ECOG) performance status of 2 or more. The definition of BR-PDAC requires one or more positive dimensions (e.g. A, B, C, AB, AC, BC or ABC). The present definition acknowledges that resectability is not just about the anatomic relationship between the tumor and vessels, but that biological and conditional dimensions are also important. The aim in presenting this consensus definition is also to highlight

    Background and purpose: Most patients with brain metastases are treated with palliative whole brain radiotherapy (WBRT). There is no established definition of palliative response. The aim of this study was to develop and test clinically useful criteria for response following palliative WBRT. Materials and methods: A prospective study was conducted of patients with symptomatic brain metastases treated with WBRT (20 Gy/5 fractions) and standardised steroid tapering. Assessments included observer rating of neurological symptoms, patient-completed symptom checklist and performance status (PS). Response criteria were operationally defined based on a combination of neurological symptoms, PS and steroid dose. Results: Seventy-five patients were accrued. At 1 month, presenting neurological symptoms were improved in 14 patients, stable in 17, and worse in 21; 23 patients were not assessed, mainly due to death or frailty. Using response criteria defined a priori, 15% (95% CI 7-23%) of patients were classified as having a response to RT, 25% no response, and 29% progression; 27% were deceased at or soon after 1 month. A revised set of criteria was tested, with less emphasis on complete tapering of steroids: they increased the proportion of patients responding to 39% (95% CI 27-50%) but didn't change the large proportion who did not benefit (44%). Conclusions: Clinical response to RT of patients with brain metastases is multifactorial, comprising symptoms, PS and other factors. Assessment of degree of palliation depend on the exact definition used. More research is needed in this important area, to help validate criteria for assessing palliation after WBRT

    Purpose: Stereotactic radiosurgery is an alternative option to neurosurgical excision in the management of patients with brain metastases. We retrospectively analyzed patients with brain metastases of malignant melanoma who were treated at our institution for outcome and prognostic factors. Patients and Methods: 64 patients with 122 cerebral metastases were treated with stereotactic radiosurgery between 1986 and 2000. Twelve patients (19%) showed neurologic symptoms at the time of treatment, and 46 patients (72%) had extracerebral tumor manifestation at that time. The median dose to the 80% isodose line, prescribed to encompass the tumor margin, was 20 Gy (range, 15-22 Gy). Results: Neurologic symptoms improved in five of twelve symptomatic patients. 41 patients remained asymptomatic or unchanged in their neurologic symptoms. Only five patients (8%) temporarily worsened neurologically after therapy despite no signs of tumor progression. With a mean follow-up time of 9.4 months, actuarial local control was 81% after 1 year. There was a statistically significant dose and size dependency of local tumor control. Median actuarial survival after treatment was 10.6 months. Patients without extracerebral tumor manifestation showed a superior survival (p = 0.04). Conclusions: Despite high local tumor control rates, the prognosis of patients with cerebral metastases of malignant melanoma remains poor. Stereotactic radiosurgery has the potential of stabilizing or improving neurologic symptoms in these patients in a palliative setting. (orig.)

  1. Obesity and kidney disease

    Directory of Open Access Journals (Sweden)

    Geraldo Bezerra da Silva Junior

    Full Text Available Abstract Obesity has been pointed out as an important cause of kidney diseases. Due to its close association with diabetes and hypertension, excess weight and obesity are important risk factors for chronic kidney disease (CKD. Obesity influences CKD development, among other factors, because it predisposes to diabetic nephropathy, hypertensive nephrosclerosis and focal and segmental glomerulosclerosis. Excess weight and obesity are associated with hemodynamic, structural and histological renal changes, in addition to metabolic and biochemical alterations that lead to kidney disease. Adipose tissue is dynamic and it is involved in the production of "adipokines", such as leptin, adiponectin, tumor necrosis factor-α, monocyte chemoattractant protein-1, transforming growth factor-β and angiotensin-II. A series of events is triggered by obesity, including insulin resistance, glucose intolerance, dyslipidemia, atherosclerosis and hypertension. There is evidence that obesity itself can lead to kidney disease development. Further studies are required to better understand the association between obesity and kidney disease.

    Full text: FDG PET/CT has traditionally been considered a method of limited use in tumors of the kidneys and excretory system. Major shortcoming of the method in kidney cancer is considered variable fixation and a more general lack of significant therapeutic alternatives that require early diagnosis of recurrence after nephrectomy. In the context of the modern methods of systemic anticancer therapy in kidney cancer, marking a significant success in terms of time to progression, the need of more detailed selection of the patients and the search methods for the early diagnosis and assessment of therapeutic response arises. While CT remains the primary method for the diagnosis of parenchymal metastases (lung, liver), the use of FDG PET/CT has a significant advantage in detecting of nodal metastasis, locoregional recurrence and bone metastasis. Interesting direction in the use of PET/CT remains the monitoring of therapeutic response to systemic therapy of metastatic kidney cancer. Unlike kidney cancer in transitional cell carcinoma of bladder (TCC), the application of FDG PET/CT is non- systematic and based on the specific clinical indications. As the main indicator can be observed the distant staging in locally advanced tumors and recurrences in restading after cystectomy. Besides the general advantages of PET/CT in terms of nodal and peritoneal involvement it should be noted that the role of the PET/CT in TCC is discussible. Application of FDG PET / CT in kidney cancer and TCC at this stage can not be considered as established, but while in TCCs, the method has sporadically application, mostly for specific clinical questions, the application in kidney cancer is significantly more systemic and in the context of systemic anti-tumor therapy allows early diagnosis and therapeutic approach modulation

    Objective: To retrospectively analyze the characteristics, treatments and survival analysis in patients with solid tumors with brain metastases (E IV) assisted in Unit Neuro-Oncology over a period of five years. Patients and methods: The records of patients (pts) with diagnosis of brain metastases from solid tumors assisted in Neuro-Oncology Unit, from 1/01/2004 and 31/12/2008. Results: 51 new patients carriers of brain metastases were treated with solid tumors. The median age at diagnosis was 57 years, ranging from 30 to 75. They corresponded to the male 37 and female 14 ratio 2.5 / 1. The majority was presented as metastases 31/51. The location was in the supratentorial region in 27 cases, posterior fossa in 11 and 13 were supra and infratentorial. In only 5 patients cranial MRI was performed in only one case and it changed the therapeutical strategy. In 35 patients he corresponded to the lung primary tumor (CBP), following cancer renal (5/51). Within the CBP, the most common histologic subtypes were to large cells and adenocarcinomas, 11 and 10, respectively. In 32 patients were not found dissemination elsewhere. Surgery + RT was performed in 30 cases, in 11 exclusive RT, exclusive surgery in 4 and 3 patients symptomatic treatment. In 39 cases did not Systemic treatment diagnosis. When a progression was only diagnosed It could make systemic treatment 5 pts. The median survival was 15.4 weeks (1-301 weeks). Conclusions: Lung cancer is the most common source of metastases brain, with a poor survival.

    Full Text Available Primary tumor excision is one of the therapies of cancer most widely used. However, the risk of metastases development still exists following tumor resection. The liver is a common site of metastatic disease for numerous cancers. Breast cancer is one of the most frequent source of metastases to the liver. The aim of this work was to evaluate the efficacy of the orally-administered Salmonella Typhi vaccine strain CVD 915 on the development of liver metastases in a mouse model of breast cancer. To this end, one group of BALB/c mice was immunized with CVD 915 via o.g. while another received PBS as a control. After 24 h, mice were injected with LM3 mammary adenocarcinoma cells into the spleen and subjected to splenectomy. This oral Salmonella-based vaccine produced an antitumor effect, leading to a decrease in the number and volume of liver metastases. Immunization with Salmonella induced an early cellular immune response in mice. This innate stimulation rendered a large production of IFN-γ by intrahepatic immune cells (IHIC detected within 24 h. An antitumor adaptive immunity was found in the liver and celiac & portal lymph nodes (LDLN 21 days after oral bacterial inoculation. The antitumor immune response inside the liver was associated with increased CD4+ and DC cell populations as well as with an inflammatory infiltrate located around liver metastatic nodules. Enlarged levels of inflammatory cytokines (IFN-γ and TNF were also detected in IHIC. Furthermore, a tumor-specific production of IFN-γ and TNF as well as tumor-specific IFN-γ-producing CD8 T cells (CD8+IFN-γ+ were found in the celiac & portal lymph nodes of Salmonella-treated mice. This study provides first evidence for the involvement of LDLN in the development of an efficient cellular immune response against hepatic tumors, which resulted in the elimination of liver metastases after oral Salmonella-based vaccination.

    Marked progress has been made in surgery for esophageal carcinoma, however, when compared to results of surgery for other carcinomas of the digestive tract, much research remains to be done. The author transplanted VX2 carcinoma, a transplantable tumor of the rabbit, to the esophagus in attempt to determine the mode of metastases of esophageal carcinoma to lymph nodes and also to observe the effect of chemotherapy (Bleomycin) and radiotherapy (Betatron). Carcinoma of the cervical esophagus metastasized to the cervical lymph nodes and then to the paratracheal lymph nodes. Carcinoma of the upper thoracic esophagus metastasized to the paratracheal lymph nodes and then to the cervical lymph nodes. Carcinoma of the mid-thoracic esophagus metastasized to the intrathoracic lymph nodes and then to the intraperitoneal lymph nodes. Carcinoma of the abdominal esophagus metastasized to the intraperitoneal lymph nodes and then to the intrathoracic lymph nodes. Skipping metastasis was rarely observed. Carcinoma of the thoracic esophagus with metastases of lymph nodes in the cervical or abdominal portion was considerably advanced, therefore it is considered that cleaning of the intrathoracic lymph nodes and simultaneous chemotherapy are required when such cases are encountered clinically. Irradiation resulted in regression in the size of the tumor and metastases to lymph nodes and there was a decrease in metastases to the distant lymph nodes. Effects of irradiation were similar on tumors and lymph nodes with positive metastases located within the field of irradiation. Bleomycin medication resulted in regression in the size of tumor and metastases to lymph nodes. Effects of Bleomycin medication were similar on tumors and lymph nodes with positive metastases.

    Full Text Available Aim of the study : To investigate the magnetic resonance imaging (MRI features of skeletal muscle metastases (SMM. Material and methods: The records of 31 patients with proven SMM were retrospectively reviewed. Clinical history, type of primary malignancy, location of metastases, and MRI features of SMM were evaluated. Based on MRI findings, SMM were divided into three MRI types. The correlation between MRI types with ages and pathology category, between MRI types of SMM and ages, as well as MRI types of SMM and pathology category were analysed with Spearman’s rho. Results: The most common primary tumour was genital tumour (25.8% and bronchial carcinoma (19.4%, and the most common cell type was adenocarcinoma (58.1%. SMM were located in the iliopsoas muscle (26.3%, paravertebral muscles (21.1%, and upper extremity muscles (18.4%. MRI features: (1 Type-I localised lesions (12.90%, round-like mass limited to local regions with heterogeneous iso-signal intensity in T1WI and heterogeneous hyper-intensity in T2WI; (2 Type-II diffuse lesions without bone destruction (35.48%, abnormal diffuse swelling of the muscle with irregular boundaries and slightly hypo- to iso-intensity in T1WI and hyper-intensity in T2WI; and (3 Type-III diffuse lesions with bone destruction (51.61%, distinct irregular lump with iso-intensity in T1WI and heterogeneous hyper-intensity in T2WI with adjacent bone invasion. There was positive correlation between MRI types and ages (r = 0.431, p 0.05. Conclusions : SMM features on MRI can be broadly used to classify lesions, which is beneficial for SMM diagnosis.

    After a long series of studies on the effects of neutron irradiation of 10B loaded neoplastic cells both in culture and in animal experiments, we started the clinical application of BNCT on humans affected by liver metastases of a radically resected colon adenocarcinoma. The procedure we adopted includes a first surgical phase, with hepatectomy; a radiotherapeutic phase, in which the isolated liver, washed and chilled, is extracorporeally irradiated with thermal neutrons; and then a second surgical phase for the reconnection of the liver to the patient. Until now two patients have been subjected to the BNCT treatment. The first one survived 44 months with a good quality of life, and died because of diffuse recurrences of his intestinal tumour. The second patient had the same early perioperative course, but after 33 days a worsening of a dilatative cardiomyopaty, from which he was suffering, determined a cardiac failure and eventually death. This clinical experience, although limited, has shown that extracorporeal neutron irradiation of the liver is a feasible procedure, able to ensure the complete destruction of liver metastases and a possible long lasting survival. In our patients neutron irradiation caused massive cellular necrosis highly specific to tumour cells, whereas normal cells were mostly spared. Nevertheless, the impact of such a traumatic operation on the patient's organism must be taken into account. Finally, we have to be aware that the fight against tumour rarely leads to a complete victory. We now have an innovative weapon which is both powerful and partly unsettled: it must be refined and above all used.

    Full Text Available Background/Aim. Most studies of esophageal and gastric adenocarcinomas have shown a very high rate of p53 gene mutation and/or protein overexpression, but the influence of the tumor site upon the frequency of p53 protein expression has not been evaluated (gastroesophageal junction, Barret's esophagus, and antrum. The aim of our study was to analyze the correlation between the selected clinico-pthological parameters, and p53 protein overexpression in regards to the particular tumor location. Methods. The material comprised 66 surgical specimens; 10 were Barrett’s carcinomas, 25 adenocarcinomas of the gastric cardia (type II adenocarcinoma of the esophagogastric junction - EGJ, and 31 adenocarcinomas of the antrum. Immunostaining for p53 protein was performed on formalin-fixed, paraffin-embedded tissue sections, using the alkaline phosphatase - antialkaline phosphatase (APAAP method. The cases were considered positive for p53 if at least 5% of the tumor cells expressed this protein by immunostaining. Results. There was no significant difference observed between the studied groups in regards to age, sex, Lauren’s classification and tumor differentiation. There was, however, a significant difference observed in the depth of tumor invasion between Barrrett’s adenocarcinoma and adenocarcinoma of the cardia compared with the adenocarcinoma of the antrum. Namely, at the time of surgery, both Barrett’s adenocarcinomas and adenocarcinomas of the cardia, were significantly more advanced comparing with the adenocarcinomas of the antrum. Overexpression of p53 was found in 40% (4/10 of Barrett’s adenocarcinomas, 72% (18/25 of adenocarcinoma of the cardia and 65% (20/31 of adenocarcinoma of the antrum. No significant differences in p53 expression in relation to sex, type (Lauren of tumor, depth of invasion, lymph node involvement, or tumor differentiation were observed in any of the analyzed groups of tumors. Patients with more advanced Barrett

    One hundred and thirty five patients with carcinoma of the nasopharynx were treated by radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University between August 1977 and July 1987. Of the 30 patients omitted: 8 had distant metastases at initial diagnosis or during radiotherapy; 18 patients refused or did not received a full course of radiation therapy, and four had not been confirmed histologically. The remaining 105 patients were analyzed to determine the incidence and patter of distant metastases. Diagnosis of distant metastases was made based on clinical signs and radiography, even though histologic confirmation was not made. Twenty-six patients developed distant metastases after definite irradiation of nasopharynx and neck, an incidence rate of 24.8%. The common sites of distant metastases were, in descending order, bone, lung, liver, and brain. There was a strong correlation between Ho's N stage and distant metastases rate. But sex, age, histologic subtype (squamous cell and undifferentiated cell), AJC T and N stage, treatment modalities (radiotherapy alone and radiotherapy combined with chemotherapy) were not significant. Of those patients who developed distant metastases, 80.8% were discovered within 2 years of their radical radiotherapy. The prognosis for nasopharyngeal carcinoma patients developing distant metastases was poor: median survival was nine months and 80% of those patients died within two years of the initial diagnosis of distant metastasis

    2015-03-01

    Full Text Available Purpose: Metastasis to adrenal gland from lung, breast, and kidney malignancies are quite common. Historically radiotherapy was intended for pain palliation. Recent studies with stereotactic body radiotherapy (SBRT including Cyberknife robotic radiosurgery aiming at disease control brings about encouraging results. Here we represent the early clinical experience with Cyberknife stereotactic system from an Indian cancer care center. The main purpose of this retrospective review is to serve as a stepping stone for future prospective studies with non- invasive yet effective technique compared to surgery. Methods: We retrospectively reviewed four cases of adrenal metastases (three: lung and one: renal cell carcinoma treated with Cyberknife SBRT. X sight spine tracking was employed for planning and treatment delivery. Patients were evaluated for local response clinically as well as with PETCT based response criteria.Results: With a median gross tumor volume of 20.5 cc and median dose per fraction of 10 Gy, two patients had complete response (CR and two had partial response (PR when assessed 8-12 weeks post treatment as per RECIST. There was no RTOG grade 2 or more acute adverse events and organs at risk dosage were acceptable. Till last follow up all the patients were locally controlled and alive. Conclusion: Cyberknife SBRT with its unique advantages like non- invasive, short duration outpatient treatment technique culminating in similar local control rates in comparison to surgery is an attractive option. World literature of linear accelerator based SBRT and our data with Cyberknife SBRT with small sample size and early follow up are similar in terms of local control in adrenal metastases. Future prospective data would reveal more information on the management of adrenal metastases.

    Full Text Available Objective: to evaluate patients treated with primary bladder adenocarcinoma at our institution. Methods: A review of 30 patients diagnosed with bladder adenocarcinoma at a single institution from 1994 of 2005 was undertaken. Cases of primary bladder adenocarcinoma were retrospectively evaluated. Rresults: Out of 490 patients with bladder carcinoma, 30 had bladder adenocarcinoma: 22 metastatic tumors, eight (1.6% primary adenocarcinoma. Of these, three (0.6% were primary non-urachal and five (1.0% were urachal adenocarcinoma. All patients were men with mean age of 55.8 years (range 37-83. Dysuria and hematuria were the main symptoms reported. Of the total, four patients had cancer-related mortality. Cconclusion: Primary bladder adenocarcinoma is a rare neoplasm, observed in 1.6% patients with bladder malignancies. Late diagnosis limits therapeutic possibilities. Partial cystectomy seems to have unsatisfactory results and radical cystectomy, although remains as the gold standard, have no proven efficacy. New methods of adjuvant treatment must be studied to improve treatment outcomes, as high mortality is observed despite treatment.

    We previously showed that different pathologic subtypes were associated with different prognostic values in patients with stage IA lung adenocarcinoma (AC). We hypothesize that differential gene expression profiles of different subtypes may be valuable factors for prognosis in stage IA lung adenocarcinoma. We performed microarray gene expression profiling on tumor tissues micro-dissected from patients with acinar and solid predominant subtypes of stage IA lung adenocarcinoma. These patients had undergone a lobectomy and mediastinal lymph node dissection at the Shanghai Chest Hospital, Shanghai, China in 2012. No patient had preoperative treatment. We performed the Gene Set Enrichment Analysis (GSEA) analysis to look for gene expression signatures associated with tumor subtypes. The histologic subtypes of all patients were classified according to the 2015 WHO lung Adenocarcinoma classification. We found that patients with the solid predominant subtype are enriched for genes involved in RNA polymerase activity as well as inactivation of the p53 pathway. Further, we identified a list of genes that may serve as prognostic markers for stage IA lung adenocarcinoma. Validation in the TCGA database shows that these genes are correlated with survival, suggesting that they are novel prognostic factors for stage IA lung adenocarcinoma. In conclusion, we have uncovered novel prognostic factors for stage IA lung adenocarcinoma using gene expression profiling in combination with histopathology subtyping.

  1. Prognostic value of E-cadherin, beta-catenin, CD44v6, and HER2/neu in metastatic cutaneous adenocarcinoma.

    2009-08-01

    Our recent experience with a patient developing cutaneous metastases within 3 months of diagnosis of esophageal adenocarcinoma suggests that altered expression of the cellular adhesion molecules, E-cadherin and CD44v6, may have had a role to play in the rapid onset of metastases. To corroborate these findings, we designed a cross-sectional study to investigate the expression of select molecules involved in the metastatic cascade. E-cadherin, beta-catenin, CD44v6, and HER2/neu immunohistochemical stains were performed on archival materials of metastatic adenocarcinoma to the skin from 27 patients and the available corresponding primary tumors in 10 patients. The primary sites included breast (n = 10; 37%), gastrointestinal tract (n = 10; 37%), ovary (n = 1; 4%), thyroid (n = 2; 7%), lung (n = 1; 4%), and unknown primary (n = 3; 11%). Expression of all markers was noted with the most significant increases observed in beta-catenin (26 of 27 cases; 96%), followed by CD44v6 (24 of 27 cases; 89%), E-cadherin (22 of 27 cases; 82%), and HER2/neu (11 of 27 cases; 41%). Contrasting expression of these molecules in the primary versus the metastatic tumors, enhanced expression of CD44v6 was observed in the cutaneous metastases relative to the primary in 6 of 10 (60%) cases. Of interest, 2 of these 6 cases (33%) also showed reduction in E-cadherin--a member of the cadherin family functioning as an invasion suppressor molecule. These findings reinforce the complexities of the metastatic cascade and imply that the variation in adhesive properties of tumor cells is, perhaps, a consequence of the difference in density of the molecules mediating this process.

  2. Unintentional Long-Term Esophageal Stenting due to a Complete Response in a Patient with Stage UICC IV Adenocarcinoma of the Gastroesophageal Junction

    2016-05-01

    Full Text Available Endoscopic stent implantation is a common short-treatment option in palliative settings in patients with esophageal cancer. Advanced disease is associated with low survival rates; therefore, data on the long-term outcome are limited. So far, cases of long-term remission or even cure of metastasized adenocarcinoma of the gastroesophageal junction or stomach (AGS have only been reported from Asia. A 51-year-old male patient primarily diagnosed with metastasized adenocarcinoma of the gastroesophageal junction (GEJ [type I, cT3cN+cM1 (hep, CEA positive, UICC stage IV] received palliative esophageal stenting with a self-expandable metal stent. As disease progressed after four cycles with epirubicin, oxaliplatin, and capecitabin, treatment was changed to 5-FU and Irinotecan. The patient did not return after 5 cycles of FOLFIRI, but presented 4 years later with mild dysphagia. Endoscopy surprisingly revealed no relevant stenosis or stent migration. Repeated histological analyses of a residual mass at the GEJ did not detect malignancy. Since the initially diagnosed hepatic metastases were no longer detectable by computed tomography, cure from esophageal cancer was assumed. Dysphagia was ascribed to esophageal motility disorder by a narrowed esophageal lumen after long-term stenting. Thus, endoscopic stent implantation is an important method in palliative treatment of dysphagia related to AGS. New systemic treatment strategies like trastuzumab in Her2neu positive cases or new VEGF-inhibitors like ramucirumab will lead to more long-time survivors with AGS. In conclusion, future endoscopic treatment strategies in AGS represent a challenge for the development of new stent techniques in either extraction or programmed complete dissolution.

    The aim of this study was to estimate the effect of exposure to secondhand tobacco smoke on the incidence of lung adenocarcinoma in situ/minimally invasive adenocarcinoma (AIS/MIA). Data from seven case-control studies participating in the International Lung Cancer Consortium (ILCCO) were pooled, resulting in 625 cases of AIS/MIA and 7,403 controls, of whom 170 cases and 3,035 controls were never smokers. Unconditional logistic regression was used to estimate adjusted ORs (ORadj) and 95% confidence intervals (CI), controlling for age, sex, race, smoking status (ever/never), and pack-years of smoking. Study center was included in the models as a random-effects intercept term. Ever versus never exposure to secondhand tobacco smoke was positively associated with AIS/MIA incidence in all subjects (ORadj = 1.48; 95% CI, 1.14-1.93) and in never smokers (ORadj = 1.45; 95% CI, 1.00-2.12). There was, however, appreciable heterogeneity of ORadj across studies (P = 0.01), and the pooled estimates were largely influenced by one large study (40% of all cases and 30% of all controls). These findings provide weak evidence for an effect of secondhand tobacco smoke exposure on AIS/MIA incidence. Further studies are needed to assess the impact of secondhand tobacco smoke exposure using the newly recommended classification of subtypes of lung adenocarcinoma. ©2015 American Association for Cancer Research.

    2016-01-01

    Abstract Background: Central nervous system (CNS) metastases occur in about 30% of patients (pts) with advanced non-small cell lung cancer (NSCLC). Local treatment strategies (e.g., radiotherapy or surgery) result in delays in systemic therapy administration and are frequently associated with neurocognitive impairment. Nivolumab is an anti-PD1 immune check-point inhibitor which has been recently approved by the FDA as a second line treatment of NSCLC. Data regarding its intracranial activity is lacking. Methods: We retrospectively reviewed efficacy and safety of nivolumab administered intravenously at a dose of 3mg/kg q2 weeks in five pts with advanced NSCLC and new or progressing intracranial metastases which were diagnosed before or within 1 month after starting the treatment. Results: Pt baseline characteristics were as follows: median age 78y (range, 52–84); 2 males; 4 smokers; ECOG PS 0/1/2 - 2 pts/1 pt/2 pts; histological subtype: adenocarcinoma/ squamous-cell carcinoma/NSCLC NOS 3 pts /1 pt/1 pt; EGFR WT/ALK neg/KRAS M all/all/2 pts. Four pts had parenchymal brain metastases, three pts had leptomeningeal disease. All pts were asymptomatic and did not require corticosteroids or immediate brain irradiation. Dramatic response in the brain was observed in two pts (including 1 pt with leptomeningeal spread demonstrating a complete response in the CNS); time-to-response comprised 5 weeks and 9 weeks; all responses are still ongoing at the time of the report (18+ weeks, 19+ weeks). In one pt stabilization of leptomeningeal carcinomatosis for 10 weeks was achieved. Systemic responses and intracranial responses were largely concordant. No treatment-related or CNS-metastases related grade ≥ 3 adverse events were observed. Conclusions: Nivolumab has a promising intracranial activity and favorable safety profile in pts with NSCLC and untreated/progressing CNS metastases. Nivolumab CNS activity warrants further evaluation.

    Various common malignant neoplasms (ie, liver, kidney, stomach and breast) have been reported to embolize to the pulmonary arterial system. This uncommon occurrence can also result from metastatic sarcoma. We report 3 cases- 2 chondrosarcomas and 1 osteosarcoma-associated with intravascular motastases to the pulmonary vasculature and discuss the clinical presentation and differentiating radiologic features on computed tomography (CT). Intravascular pulmonary tumour emboli may present with nonspecific respiratory symptoms or remain completely asymptomatic, and therefore, many patients are often misdiagnosed with thromboembolic disease or undiagnosed until autopsy. Chest CTs in all our patients demonstrated a striking pattern of multifocal tubular branching beaded opacities along the pulmonary vasculature in a multilobular distribution. Our observations and a review of the literature indicate that chest CT is the most useful diagnostic tool for detecting intravascular pulmonary tumour emboli. CT can distinguish this entity from mucous plugging by demonstrating the normal adjacent bronchus. The tubular nature of these metastases distinguishes them from the more common parenchymal metastases. (author)

    Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer death in the USA, accounting for ~40,000 deaths annually. The dismal prognosis for PDAC is largely due to its late diagnosis. Currently, the most sensitive diagnosis of PDAC requires invasive procedures, such as endoscopic ultrasonography, which has inherent risks and accuracy that is highly operator dependent. Here we took advantage of a general characteristic of solid tumors, the acidic microenvironment that is generated as a by-product of metabolism, to develop a novel approach of using pH (Low) Insertion Peptides (pHLIPs) for imaging of PDAC. We show that fluorescently labeled pHLIPs can localize and specifically detect PDAC in human xenografts as well as PDAC and PanIN lesions in genetically engineered mouse models. This novel approach may improve detection, differential diagnosis and staging of PDAC.

    Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis, with a 5-year survival rate of 7.7%. Most patients are diagnosed at an advanced stage not amenable to potentially curative resection. A substantial portion of this review is dedicated to reviewing the current literature on carbohydrate antigen (CA 19-9), which is currently the only guideline-recommended biomarker for PDAC. It provides valuable prognostic information, can predict resectability, and is useful in decision making about neoadjuvant therapy. We also discuss carcinoembryonic antigen (CEA), CA 125, serum biomarker panels, circulating tumor cells, and cell-free nucleic acids. Although many biomarkers have now been studied in relation to PDAC, significant work still needs to be done to validate their usefulness in the early detection of PDAC and management of patients with PDAC.

Clinical examination showed non-specific findings of the intraoral region, but showed asymmetrical facial appearance. Panoramic view showed a large amorphous calcified mass on the posterior to the mandibular ramus and thin cortical plate of the posterior ramus. Sialogram showed constriction of the main duct and no further filling of striated, intercalated ducts and parenchymal areas. CT scans demonstrated an irregular, infiltrating mass with slight enhancement in the right parotid gland. The mass showed necrotic areas and calcifications. Bone scan showed marked accumulation of {sup 99m}Tc-MDP on the right posterior maxilla. Microscopic findings demonstrated the minimal morphologic alterations and rare mitotic figures within tumor cells, and diagnosed as adenocarcinoma (NOS, Grade II). This report could be aid in the diagnosis of calcified lesions of the salivary gland.

    Purpose: Respiratory-induced excursions of locally advanced pancreatic adenocarcinoma could affect dose delivery. This study quantified tumor motion and evaluated standard treatment margins. Methods and Materials: Respiratory-correlated four-dimensional computed tomography images were obtained on 30 patients with locally advanced pancreatic adenocarcinoma; 15 of whom underwent repeat scanning before cone-down treatment. Treatment planning software was used to contour the gross tumor volume (GTV), bilateral kidneys, and biliary stent. Excursions were calculated according to the centroid of the contoured volumes. Results: The mean ± standard deviation GTV excursion in the superoinferior (SI) direction was 0.55 ± 0.23 cm; an expansion of 1.0 cm adequately accounted for the GTV motion in 97% of locally advanced pancreatic adenocarcinoma patients. Motion GTVs were generated and resulted in a 25% average volume increase compared with the static GTV. Of the 30 patients, 17 had biliary stents. The mean SI stent excursion was 0.84 ± 0.32 cm, significantly greater than the GTV motion. The xiphoid process moved an average of 0.35 ± 0.12 cm, significantly less than the GTV. The mean SI motion of the left and right kidneys was 0.65 ± 0.27 cm and 0.77 ± 0.30 cm, respectively. At repeat scanning, no significant changes were seen in the mean GTV size (p = .8) or excursion (p = .3). Conclusion: These data suggest that an asymmetric expansion of 1.0, 0.7, and 0.6 cm along the respective SI, anteroposterior, and medial-lateral directions is recommended if a respiratory-correlated four-dimensional computed tomography scan is not available to evaluate the tumor motion during treatment planning. Surrogates of tumor motion, such as biliary stents or external markers, should be used with caution.

    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.

    Lung cancer is one of the most frequent malignancies, with high mortality rates. It can metastasize in almost all organs, but more often invades hilar nodes, liver, adrenal glands, bones and brain. There are various data on the incidence of lung cancer metastases in the skin. In 1-12% of patients with lung cancer are developed skin metastases. Metastases in the skin may be the first sign of lung cancer. Forty-five years old Albanian male, smoker, was admitted to our department with multiple nodules localized in the skin of the head, neck, back and chest. The nodules measuring 5-15 millimeters in greatest dimension were round and skin-colored, with telangiectasias, firm and tender. They appeared in an eruptive form about two weeks before being admitted at our hospital. In addition, the patient exhibited signs of weight loss, anorexia and fatigue. Excisional biopsy was performed to one of the lesions. Histopathology confirmed metastatic nature of the lesion namely, malignant tumor of neuroendocrine phenotype consistent with small-cell carcinoma. Chest X-ray and computed tomography revealed an expansive process in the 7(th) segment of the left lung, left hilar and mediastinal lymphadenopathy and a suspicious initial secondary deposit in the left adrenal gland. The patient was referred to the department of oncology for further treatment. After the third cycle of chemotherapy, the magnetic resonance imaging revealed brain metastases. The patient passed away four months after the diagnosis of lung cancer first presented with skin metastases. Metastases in skin may be the first sign of lung cancer. Although rare appearing, we should raise suspicion in cases of atypical lesions in the skin not only of the smokers, but also of the non-smokers. Skin metastases from small-cell lung carcinoma are a poor prognostic indicator. The appearance of multiple skin metastases with other internal metastases shorten the survival time.

    High dosage regional chemotherapy, chemoembolization and other methods of regional treatment are commonly used to treat unresectable primary liver malignancies and liver metastases. In liver malignancies of childhood neoadjuvant chemotherapy is successfully combined with surgical treatment. Chemotherapy and local tumor ablation lead to characteristic histomorphologic changes: Complete destruction of the tumor tissue and its vascular bed is followed by encapsulated necroses. After selective eradication of the tumor cells under preservation of the fibrovasular bed the tumor is replaced by hypocellular edematous and fibrotic tissue. If completely damaged tumor tissue is absorbed quickly, the tumor area is replaced by regenerating liver tissue. Obliterating fibrohyalinosis of tumor vessels, and perivascular edema or necrosis indicate tissue damage along the vascular bed. Degenerative pleomorphism of tumor cells, steatosis, hydropic swelling and Malloryhyalin in HCC can represent cytologic findings of cytotoxic cellular damage. Macroscopic type of HCC influences significantly the response to treatment. Multinodular HCC often contain viable tumor nodules close to destroyed nodules after treatment. Encapsulated uninodular tumors undergo complete necrosis much easier. Large size and a tumor capsule limitate the effect of percutaneous injection of ethanol into HCC. In carcinomas with an infiltrating border, especially in metastases of adenocarcinomas and hepatic cholangiocarcinoma cytostatic treatment damages the tumor tissue mainly in the periphery. Nevertheless the infiltrating rim, portal veins, lymphatic spaces and bile ducts as well as the angle between liver capsule, tumor nodule and bordering parenchyma are the main refugees of viable tumor tissue even after high dosage regional chemotherapy. This local resistance is caused by special local conditions of vascularization and perfusion. These residues are the source of local tumor progression and distant metastases

  18. Reduced expression of the polymeric immunoglobulin receptor in pancreatic and periampullary adenocarcinoma signifies tumour progression and poor prognosis.

    Richard Fristedt

    Full Text Available The polymeric immunoglobulin receptor (pIgR is a key component of the mucosal immune system that mediates epithelial transcytosis of immunoglobulins. High pIgR expression has been reported to correlate with a less aggressive tumour phenotype and an improved prognosis in several human cancer types. Here, we examined the expression and prognostic significance of pIgR in pancreatic and periampullary adenocarcinoma. The study cohort encompasses a consecutive series of 175 patients surgically treated with pancreaticoduodenectomy for pancreatic and periampullary adenocarcinoma in Malmö and Lund University Hospitals, Sweden, between 2001-2011. Tissue microarrays were constructed from primary tumours (n = 175 and paired lymph node metastases (n = 105. A multiplied score was calculated from the fraction and intensity of pIgR staining. Classification and regression tree analysis was used to select the prognostic cut-off. Unadjusted and adjusted hazard ratios (HR for death and recurrence within 5 years were calculated. pIgR expression could be evaluated in 172/175 (98.3% primary tumours and in 96/105 (91.4% lymph node metastases. pIgR expression was significantly down-regulated in lymph node metastases as compared with primary tumours (p = 0.018. Low pIgR expression was significantly associated with poor differentiation grade (p < 0.001, perineural growth (p = 0.027, lymphatic invasion (p = 0.016, vascular invasion (p = 0.033 and infiltration of the peripancreatic fat (p = 0.039. In the entire cohort, low pIgR expression was significantly associated with an impaired 5-year survival (HR = 2.99, 95% confidence interval (CI 1.71-5.25 and early recurrence (HR = 2.89, 95% CI 1.67-4.98. This association remained significant for survival after adjustment for conventional clinicopathological factors, tumour origin and adjuvant treatment (HR = 1.98, 95% CI 1.10-3.57.

    To determine MR features suggestive of mass-forming cholangiocarcinoma (CCA) or liver metastases of adenocarcinoma of unknown primary (AUP), and to compare the ability of two experienced radiologists to establish the correct diagnosis. 61 patients with CCA or AUP, with MRIs were placed into two groups: population 1, 28 patients with certain diagnosis of either CCA or AUP; and population 2, 33 patients with uncertain diagnosis. Using population 1 with known diagnosis, two investigators formulated imaging criteria for CCA or AUP, which represented phase 1 of the study. In phase 2, two independent radiologists categorized the patients in populations 1 and 2 as CCA or AUP using the formulated criteria. This categorization was compared with the patient medical records and pathologist review. Findings were tested for statistical significance. In phase 1, solitary lesion, multifocal lesions with dominant lesion, capsule retraction, and porta hepatis lymphadenopathy were features of CCA; multifocal lesions with similar size, and ring enhancement were features of AUP. The number of lesions, capsule retraction, and early tumor enhancement pattern were observed to be significant features (P AUP are identifiable on MRI images, which may aid the radiologist to establish the correct diagnosis.

    We measured the serum concentration of a panel of inflammatory cytokines and evaluated their association with circulating proangiogenic biomarkers and with outcome in patients with pancreatic ductal adenocarcinoma (PDAC). We collected serum samples from 36 patients with PDAC, 9 patients with chronic pancreatitis, and 22 healthy volunteers as a control. Inflammatory cytokines and proangiogenic biomarkers were measured using the multianalyte xMAP array and carcinoembryonic antigen (CEA) and carbohydrate 19-9 by immunoassay. Patients with PDAC had higher circulating levels of interleukin 6 (IL-6) than those of patients with pancreatitis or healthy individuals and higher levels of IL-10 and tumor necrosis factor α (TNF-α) compared with those of healthy individuals. In patients with PDAC, circulating IL-6, TNF-α, IL-1β, and IL-10 correlated with serum concentrations of vascular endothelial growth factor and basic fibroblast growth factor; circulating IL-6, IL-1β, and TNF-α correlated with carbohydrate 19-9; and IL-8, IL-10, and TNF-α correlated with CEA levels. Circulating IL-8, TNF-α, and CEA; tumor stage; and lymph node metastases were associated with a poor outcome. The results of this exploratory study indicate that inflammatory cytokines should be pursued as potential prognostic biomarkers as well as targets for therapy in larger studies in PDAC.

  2. Lung Adenocarcinoma Presenting as Worsening of Chronic Neck Pain—A Cautionary Tale

    2017-02-01

    Full Text Available Introduction: Neck pain is a common musculoskeletal problem that up to 70% of the world population will experience at some point in their lives. Intramedullary spinal cord metastasis is an exceedingly rare complication of malignancy that affects less than 1% of all patients with cancer. Case report: We report a case of a 61-year-old man who presented to primary care clinic with 1-month history of worsening neck pain with associated neurologic deficits. Despite initial conservative management, the patient continued to have progressive worsening of sensory and motor deficits. Magnetic resonance imaging of the cervical spine showed vasogenic edema of the brain and spinal cord and nodularity at the C4-C5 level. A computed tomography of the chest showed a dense lesion in the left lower lobe of the lung; histopathology of the biopsied specimen was consistent with moderately differentiated lung adenocarcinoma. Conclusions: A high index of suspicion is necessary when chronic neck pain acutely worsens, changes in character, or is accompanied by neurologic deficits. These clinical signs warrant further investigation into a secondary cause of neck pain. Intramedullary spinal cord metastases are rare complications of systemic cancer that commonly present with neck pain and upper extremity paraesthesias; early diagnosis and management are necessary to prevent complications such as spinal cord hemisection syndrome or spinal cord transection.

    The present investigation describes a series of 25 patients with solitary metastasis from a renal adenocarcinoma. Forty-eight percent of the patients had metastatic foci in bones, 24% in the lungs, and 28% in a variety of organs. Radiotherapy was the treatment for 64% of the patients, surgery for 36%. Disease control after treatment was obtained in 88% of the patients. The 5-year survival rate was 39%. Sixteen of 25 patients died after a mean survival time of 36 months; 9/25 patients are still living 28-126 months after treatment. Women survived significantly better than men. Patients with normal pre- and post-treatment erythrocyte sedimentation rate (ESR) survived significantly longer than patients with elevated ESR. A definite relationship between ESR and disease activity was demonstrated in 64% of the patients. It is concluded that solitary metastases in bones can be treated with radiotherapy; even if 64% of the patients die there is significant clinical remission to be obtained after aggressive treatment. Furthermore, ESR seems to be an important indicator of prognosis and disease activity

    Aim: Peritoneal metastases (PM) are usually from intra-abdominal primary neoplasms, such as carcinoma of the stomach, colon, ovary, and pancreas, or from intra-abdominal lymphoma. Metastases disseminate throughout the peritoneum in four ways: 1) direct spread along peritoneal ligaments, mesenteries and omenta; 2) via the flow of ascitis fluid. 3) lymphatic extension, and 4) embolic hematogenous spread. Although CT is quite specific in identifying PM it is not very sensitive, and peritoneal lavage or biopsy can be very useful but have sampling errors. This study assessed the clinical value of FDG-PET for the detection of PM of malignant diseases. Materials and Methods: 15 FDG-PET scans of patients referred for recurrence (mean age = 54 y/o, sex = 6M, 9F), with metabolic abnormalities suspicious findings of PM from carcinoma of the colon (7), ovary (3), lymphoma (2), pancreas (1), gastrointestinal stromal tumor (1) and melanoma (1) were reviewed. The whole-body studies were performed 50 min following the intravenous administration of 370 MBq of 18F-FDG, in a high resolution dedicated PET scanner (Advance, GEMS), with images reconstructed using a iterative algorithm with segmented attenuation correction. Visual interpretation and SUV values were correlated with CT/MRI findings and biopsy/follow-up. Results: Of the 15 patients, 7 showed <3 sites of focal uptake and 8 presented multiple foci or a diffuse hypermetabolism in the abdomen (SUVmax3.04-18.83 g/ml). 6 patients had biopsy confirmation by PET-directed surgery (6 proven PM, 0 negative biopsies). 11 FDG-PET scans had correspondence with the CT/MRI findings and 4 showed discrepancies (PET positive-CT/MRI negative in patients with isolated raising tumor markers levels or unsuspected PM). FDG-PET influenced the therapeutic management in 2 patients as presented multiple metastases leading them from surgery to chemotherapy. Conclusion: When used as a complementary imaging tool to the conventional work up, FDG-PET is

  12. Kidney compartment model

    International Nuclear Information System (INIS)

    Gullberg, G.T.

    1976-09-01

    A multiparameter kidney compartment model which quantitates the amount of iodohippurate concentration as a function of time in the blood, tissue, kidneys and bladder is developed from a system of differential equations which represent first order kinetics. The kinetic data are obtained using a gamma camera and an HP5407 computer system which allows one to delineate areas of interest for the blood and tissue, kidneys, and bladder thus separating the data into four data sets. The estimated tubular transit times have a high ratio of the signal to the variance whereas the estimates of the amount of iodohippurate in the blood, tissue and kidneys have a low ratio of the signal to the variance. Application of this model to patient data requires better statistics than available with conventional 131 I-hippurate doses; thus a true test of the efficacy awaits availability of 123 I-hippurate

    To report epidemiology and characteristics of end-stage renal disease (ESRD) patients and renal transplant candidates, and to evaluate access to waiting list and results of renal transplantation. An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: "chronic kidney disease, epidemiology, kidney transplantation, cost, survival, graft, brain death, cardiac arrest, access, allocation". French legal documents have been reviewed using the government portal (http://www.legifrance.gouv.fr). Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and recommendations were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 3234 articles, 6 official reports and 3 newspaper articles were identified; after careful selection 99 publications were eligible for our review. The increasing prevalence of chronic kidney disease (CKD) leads to worsen organ shortage. Renal transplantation remains the best treatment option for ESRD, providing recipients with an increased survival and quality of life, at lower costs than other renal replacement therapies. The never-ending lengthening of the waiting list raises issues regarding treatment strategies and candidates' selection, and underlines the limits of organ sharing without additional source of kidneys available for transplantation. Allocation policies aim to reduce medical or geographical disparities regarding enrollment on a waiting list or access to an allotransplant. Copyright © 2016 Elsevier Masson SAS.

    Many factors affect the graft and patient survival on the renal transplant outcome. These factors depend so much of the recipient and donor. We accomplished a study trying to circumvent factors that depend on the donor. We checked the paired kidneys originating of a same donor cadaver. We examined the risk factors in the evolution and follow-up in 278 couples of kidney transplant. We describe their differences, significance, the graft and patient survival, their functionality in 3 and 5 years and the risk factors implicated in their function. We study immunogenic and no immunogenic variables, trying to explain the inferior results in the grafts that are established secondly. We regroup the paired kidneys in those that they did not show paired initial function within the same couple. The results yield a discreet deterioration in the graft and patient survival for second group establish, superior creatinina concentration, without obtaining statistical significance. The Cox regression study establishes the early rejection (inferior to three months) and DR incompatibility values like risk factors. This model of paired kidneys would be able to get close to best-suited form for risk factors analysis in kidney transplant from cadaver donors, if more patients examine themselves in the same way. The paired kidneys originating from the same donor do not show the same function in spite of sharing the same conditions of the donor and perioperative management.

    Full Text Available Anti-neutrophil cytoplasmic antibodies (ANCA play an important role in the pathogenesis of pauci-immune renal vasculitis. However, in 10% of the cases, ANCA are absent. We present a case of a 64-year-old man with a chronic untreated hepatitis C virus infection and Middle Eastern thalassemia who was ANCA-negative when he was hospitalized due to acute kidney injury and accounts for an uncommon presentation of renal vasculitis. The patient had earlier reported to have undergone local lobectomy and adjuvant chemotherapy (carboplatin/pemetrexed for lung adenocarcinoma a month prior. IL-6 has been reported to be involved in the pathophysiological cascade causing pauci-immune glomerulonephritis amongst non-small cell lung cancer patients. Previous studies with subgroup analysis have demonstrated that ANCA negativity has been associated with more chronic glomerular lesions and less crescent formation, which tends to have a critical outcome in the renal system. However, our patient underwent kidney biopsy exhibiting active crescentic glomerulonephritis, pauci-immune type with 5 cellular crescents amongst 15 glomeruli. To our knowledge, this is the third reported case of ANCA-negative vasculitis with typical presentation on biopsy in non-small cell lung cancer patients.

    Kidney cancer is the third most frequent urologic cancer in Lebanon after prostate and bladder cancer, accounting for 1.5% of all diagnosed cancers. In this paper, we report the histologic characteristics and distribution of kidney cancer, never described in Lebanon or the Middle East. Pathology results of operated kidney cancer were collected during a two year period (2010-2011) from two different Lebanese hospitals (Hotel-Dieu de France University Hospital and Saint Joseph Hospital). A total of 124 reports were reviewed and analyzed according to WHO classification of 2009. The 124 patients diagnosed with kidney cancer had a median age of 62.4 [18-86], 75% being men and 25% women. Some 71 % of the lesions were renal cell carcinoma (RCC), 25.8% had a urothelial histology, 1.6% were lymphomas and 1.6% were metastases to the kidney. Patients having RCC had a median age of 60.3 [18-85], 77.3% were men and 22.7% women. Of the RCCs, 59.1% were clear cell carcinoma, 22.7% papillary, 11.4% chromophobic, 3.4% rom the collecting ducts of Bellini and 3.4% were not otherwise classified. Histological distribution of Lebanese kidney cancer seems unusual when compared to the literature. The percentage of urothelial renal pelvis tumors is strikingly high. Moreover, clear cell carcinoma accounts for only 59.1% of RCCS in contrast to the 75% described elsewhere, while papillary carcinoma represents more than 22.7% compared to 10%.

  19. 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.

    Estimation of skeletal muscle metastases (SMMs) at the time of diagnosis and/or initial staging of lung cancer. Retrospective evaluation of clinical charts and imaging data suggestive of SMMs of patients with histology-proved lung cancer over a 5-year period. SMMs were identified in 46 out of 1,754 patients. Single and multiple (62.9% of cases) SMMs were detected by total body multi-detector computed tomography (MDCT). They were associated with poorly differentiated (43%) and advanced adenocarcinomas (52%) without clinically relevant symptoms and/or signs. Psoas and buttock muscles were most frequently involved (33.3%). MDCT findings consisted of well-defined homogeneously hyperdense oval masses (31%), lesions with ring-like enhancement and central hypoattenuation (68%), or large abscess-like necrotic lesions (24%). Sonography revealed well-defined hypoechoic masses (41.6%), ill-defined hypoechoic lesions (33.3%), or anechoic areas with a necrotic centre (25%). Positron emission tomography revealed that all SMMs were metabolically active. SMMs are uncommon but not negligible in lung cancer, with an estimated prevalence of 2.62% in our series. Although histology remains the recommended method, use of high-performance imaging techniques and increased clinical suspicion may improve their early detection. Efforts addressing their effect on the natural history of lung cancer are needed.

  1. Advanced Mesodermal (Müllerian Adenosarcoma of the Ovary: Metastases to the Lungs, Mouth, and Brain

    2015-01-01

    Full Text Available Background. A malignant mixed Müllerian tumor (MMMT is a malignant neoplasm found in the uterus, the ovaries, the fallopian tubes, and other parts of the body that contains both carcinomatous (epithelial tissue and sarcomatous (connective tissue components. Outcome of MMMTs is determined primarily by depth of invasion and stage. The metastatic background of these lesions is controversial and unknown. Case Report. A 75-year-old woman was admitted to the hospital with anorexia, weakness, and persistent coughing. The imaging exams revealed a solid, promiscuous lesion of 16 × 14 cm in dimensions located into the small pelvis, surrounding the uterus and the ovaries. The patient underwent exploratory laparotomy. The mass was removed and the histological examination of the specimen revealed an advanced mesodermal adenocarcinoma of the ovary (MMMT. Nine days after the operation the patient presented with metastatic lesions in the mouth as well as the lungs. Within a month after the discharge from the hospital metastatic lesions of the MMMT were also depicted in the CT brain scan. Conclusion. Despite the fact that sarcomas have a long-term metastatic potential, to our knowledge this is the first case of Müllerian adenosarcoma presenting with such extraperitoneal metastases.

  2. BITC Sensitizes Pancreatic Adenocarcinomas to TRAIL-induced Apoptosis

    Directory of Open Access Journals (Sweden)

    Christina A. Wicker

    2009-01-01

    Full Text Available Pancreatic adenocarcinoma is an aggressive cancer with a greater than 95% mortality rate and short survival after diagnosis. Chemotherapeutic resistance hinders successful treatment. This resistance is often associated with mutations in codon 12 of the K-Ras gene (K-Ras 12, which is present in over 90% of all pancreatic adenocarcinomas. Codon 12 mutations maintain Ras in a constitutively active state leading to continuous cellular proliferation. Our study determined if TRAIL resistance in pancreatic adenocarcinomas with K-Ras 12 mutations could be overcome by first sensitizing the cells with Benzyl isothiocyanate (BITC. BITC is a component of cruciferous vegetables and a cell cycle inhibitor. BxPC3, MiaPaCa2 and Panc-1 human pancreatic adenocarcinoma cell lines were examined for TRAIL resistance. Our studies show BITC induced TRAIL sensitization by dual activation of both the extrinsic and intrinsic apoptotic pathways.

    Primary adenocarcinoma of lung has replaced squamous cell carcinoma as the commonest histological subtype of lung cancer and the incidence of primary lung adenocarcinoma appears to be rising. Although the main factors behind this ‘epidemic-like’ situation are largely undiscovered, filter cigarettes appear to significantly contribute to this shift in the histopathological spectrum. The new multidisciplinary classification of adenocarcinoma of lung was introduced to address advances in clinical, pathological, radiological and molecular sciences. The purpose of this essay is to discuss various classes of lung adenocarcinoma in the new classification with their classical imaging features on computed tomography and summarise the recent advances in the field of radiology and review radiology recommendations.

    2006-01-01

    The Taormina project developed a new method for BNCT treatment of multifocal unresectable liver metastases based on whole liver autograft. The Roffo Institute liver surgeons propose a new technique based on partial liver autograft that would pose less risk to the patient but would require significant healthy liver regeneration following BNCT. The aim of the present study was to assess the effect of BPA, GB-10 (Na 2 10 B 10 H 10 ) and (GB-10 + BPA) and of BNCT mediated by these boron compounds on normal liver regeneration in the Wistar rat. Normal liver regeneration, body weight, hemogram, liver and kidney function were assessed following partial hepatectomy post administration of BPA, GB-10 or (GB-10 + BPA) and post in vivo BNCT at the RA-6 Reactor. These end-points were evaluated 9 days following partial hepatectomy, the time at which complete liver regeneration occurs in untreated controls. The corresponding biodistribution studies were conducted to perform dosimetric calculations. BPA, GB-10 and (GB-10 + PBA) and in vivo BNCT mediated by these boron compounds in dose ranges compatible with therapy did not cause alterations in the outcome of normal liver regeneration, and did not induce alterations in body weight, hemogram, liver or kidney function. The experimental data available to date support the development of a new BNCT protocol for the treatment of liver metastases that requires the regeneration of normal liver past-BNCT. (author)

    Purpose: Based on reports of safety and efficacy, stereotactic body radiotherapy (SBRT) for treatment of malignant spinal tumors was initiated at our institution. We report prospective results of this population at Mayo Clinic. Materials and Methods: Between April 2008 and December 2010, 85 lesions in 66 patients were treated with SBRT for spinal metastases. Twenty-two lesions (25.8%) were treated for recurrence after prior radiotherapy (RT). The mean age of patients was 56.8 {+-} 13.4 years. Patients were treated to a median dose of 24 Gy (range, 10-40 Gy) in a median of three fractions (range, 1-5). Radiation was delivered with intensity-modulated radiotherapy (IMRT) and prescribed to cover 80% of the planning target volume (PTV) with organs at risk such as the spinal cord taking priority over PTV coverage. Results: Tumor sites included 48, 22, 12, and 3 in the thoracic, lumbar, cervical, and sacral spine, respectively. The mean actuarial survival at 12 months was 52.2%. A total of 7 patients had both local and marginal failure, 1 patient experienced marginal but not local failure, and 1 patient had local failure only. Actuarial local control at 1 year was 83.3% and 91.2% in patients with and without prior RT. The median dose delivered to patients who experienced local/marginal failure was 24 Gy (range, 18-30 Gy) in a median of three fractions (range, 1-5). No cases of Grade 4 toxicity were reported. In 1 of 2 patients experiencing Grade 3 toxicity, SBRT was given after previous radiation. Conclusion: The results indicate SBRT to be an effective measure to achieve local control in spinal metastases. Toxicity of treatment was rare, including those previously irradiated. Our results appear comparable to previous reports analyzing spine SBRT. Further research is needed to determine optimum dose and fractionation to further improve local control and prevent toxicity.

    Over the past 6 years, the authors evaluated 300 patients with hepatoma as part of phase 1 and 2 treatment protocol trials. Analysis of the available clinical data and radiographic studies revealed 22 patients (7.3%) with skeletal metastases demonstrated by radiography, computed tomography (CT), and/or nuclear scintigraphy. The plain film appearance of skeletal metastases from hepatoma was osteolytic in all cases. CT scanning best demonstrated the expansile, destructive nature of these metastases, which were often associated with large, bulky soft-tissue masses. Skeletal metastases from hepatomas demonstrated increased radiotracer uptake on standard bone scans and were gallium avid, similar to the hepatoma itself. In addition, they could be targeted therapeutically with I-131 antiferritin immunoglobulin. The most frequent sites of skeletal metastases were the ribs, spine, femur, pelvis, and humerus. An initial symptom in ten patients was skeletal pain corresponding to the osseous metastases. In five patients, pathologic fractures of the proximal femur or humerus developed and required total hip replacement or open-reduction internal fixation. Patients with long-standing cirrhosis or known hepatocellular carcinoma who also have skeletal symptoms should be evaluated for possible osseous metastases

    Malignant gliomas account for approximately 60% of all primary brain tumors in adults. Prognosis for these patients has not significantly changed in recent years— despite debulking surgery, radiotherapy and cytotoxic chemotherapy—with a median survival of 9–12 months. Virtually no patients are cured of their illness. Malignant gliomas are usually locally invasive tumors, though extra-neural metastases can sometimes occur late in the course of the disease (median of two years). They generally appear after craniotomy although spontaneous metastases have also been reported. The incidence of these metastases from primary intra-cranial malignant gliomas is low; it is estimated at less than 2% of all cases. Extra-neural metastases from gliomas frequently occur late in the course of the disease (median of two years), and generally appear after craniotomy, but spontaneous metastases have also been reported. Malignant glioma metastases usually involve the regional lymph nodes, lungs and pleural cavity, and occasionally the bone and liver. In this review, we present three cases of extra-neural metastasis of malignant gliomas from our department, summarize the main reported cases in literature, and try to understand the mechanisms underlying these systemic metastases.

    Objective: The spine is the most common location for bone metastases. Since cure is not possible, local control and relief of symptoms is the basis for treatment, which is grounded on the use of conventional radiotherapy. Recently, spinal radiosurgery has been proposed for the local control of spinal metastases, whether as primary or salvage treatment. Consequently, we carried out a literature review in order to analyze the indications, efficacy, and safety of radiosurgery in the treatment of spinal metastases. Methods: We have reviewed the literature using the PubMed gateway with data from the Medline library on studies related to the use of radiosurgery in treatment of bone metastases in spine. The studies were reviewed by all the authors and classified as to level of evidence, using the criterion defined by Wright. Results: The indications found for radiosurgery were primary control of epidural metastases (evidence level II), myeloma (level III), and metastases known to be poor responders to conventional radiotherapy – melanoma and renal cell carcinoma (level III). Spinal radiosurgery was also proposed for salvage treatment after conventional radiotherapy (level II). There is also some evidence as to the safety and efficacy of radiosurgery in cases of extramedullar and intramedullar intradural metastatic tumors (level III) and after spinal decompression and stabilization surgery. Conclusion: Radiosurgery can be used in primary or salvage treatment of spinal metastases, improving local disease control and patient symptoms. It should also be considered as initial treatment for radioresistant tumors, such as melanoma and renal cell carcinoma. (author)

    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.

    During routine investigations, we are surprised to find that therapy for bone metastases is sometimes delayed for a considerable period of time. To determine the extent of this delay and its causes, we reviewed the medical records of symptomatic patients seen at our hospital who had been recently diagnosed as having bone metastases for the last four years. The treatment delay was defined as the interval between presentation with symptoms and definitive treatment for bone metastases. The diagnostic delay was defined as the interval between presentation with symptoms and diagnosis of bone metastases. The results of diagnostic radiological examinations were also reviewed for errors. The study population included 76 males and 34 females with a median age of 66 years. Most bone metastases were diagnosed radiologically. Over 75% of patients were treated with radiotherapy. The treatment delay ranged from 2 to 307 days, with a mean of 53.3 days. In 490 radiological studies reviewed, we identified 166 (33.9%) errors concerning 62 (56.4%) patients. The diagnostic delay was significantly longer for patients with radiological errors than for patients without radiological errors (P < 0.001), and much of it was due to radiological errors. In conclusion, the treatment delay in patients with symptomatic bone metastases was much longer than expected, and much of it was caused by radiological errors. Considerable efforts should therefore be made to more carefully examine the radiological studies in order to ensure prompt treatment of bone metastases. (author)

  16. Multiple urinary bladder masses from metastatic prostate adenocarcinoma

    Full Text Available We present an unusual case of metastatic prostate adenocarcinoma that manifested with multiple exophytic intravesical masses, mimicking a multifocal primary bladder tumor. Biopsy with immunohistochemical analysis confirmed metastatic prostate adenocarcinoma. The patient was treated palliatively with external beam radiotherapy to prevent possible symptoms from local tumor progression. This case illustrates that when a patient with known prostate cancer presents with multifocal bladder tumors, the possibility of metastatic prostate cancer should be considered.

    Abstract Phyllodes tumors are rare breast neoplasms. Surgery is the treatment of choice. The role of postoperative radiotherapy and chemotherapy is still under dispute, as there are no equivocal prognostic factors. Treatment failure results in the occurrence of distant metastasis—mainly to the lungs, bones, liver, and brain. We have described the case of a woman with a malignant phyllodes tumor of the breast that was surgically treated. She did not receive adjuvant therapy because there is no...

    We report the biodistribution and radiation dosimetry of an integrin α v β 3 specific PET tracer 18 F-AlF-NOTA-E[PEG 4 -c(RGDfk)] 2 (denoted as 18 F-Alfatide II). We also assessed the value of 18 F-Alfatide II in patients with brain metastases. A series of torso (from the skull to the thigh) static images were acquired in five healthy volunteers (3 M, 2 F) at 5, 10, 15, 30, 45, and 60 min after injection of 18 F-Alfatide II (257 ± 48 MBq). Regions of interest (ROIs) were drawn manually, and the time-activity curves (TACs) were obtained for major organs. Nine patients with brain metastases were examined by static PET imaging with 18 F-FDG (5.55 MBq/kg) and 18 F-Alfatide II. Injection of 18 F-Alfatide II was well tolerated in all healthy volunteers, with no serious tracer-related adverse events found. 18 F-Alfatide II showed rapid clearance from the blood pool and kidneys. The total effective dose equivalent (EDE) and effective dose (ED) were 0.0277 ± 0.003 mSv/MBq and 0.0198 ± 0.002 mSv/MBq, respectively. The organs with the highest absorbed dose were the kidneys and the spleen. Nine patients with 20 brain metastatic lesions identified by MRI and/or CT were enrolled in this study. All 20 brain lesions were visualized by 18 F-Alfatide II PET, while only ten lesions were visualized by 18 F-FDG, and 13 by CT. F-Alfatide II is a safe PET tracer with a favorable dosimetry profile. The observed ED suggests that 18 F-Alfatide II is feasible for human studies. 18 F-Alfatide II has potential value in finding brain metastases of different cancers as a biomarker of angiogenesis.

    This article describes an unusual finding in a patient who presented with an adenocarcinoma of the prostate and right hydronephrosis. A 68-year-old male presented with right hydronephrosis and a PSA of 96. DRE was consistent with cT3 carcinoma. Cystoscopy showed an exophytic superficial transitional cell carcinoma (TCC) of the bladder and a transrectal biopsy of the prostate confirmed adenocarcinoma Gleason score 4+3. Staging investigations (CT pelvis and bone scan) were negative; androgen deprivation therapy was therefore initiated for the prostatic adenocarcinoma. Upper tract imaging showed multiple filling defects in the proximal ureter. Ureteroscopy showed a stricture at the level of the iliac vessels. With a working diagnosis of upper tract TCC, right open nephroureterectomy was performed. Final histology showed prostatic adenocarcinoma infiltrating the adventitia of the entire ureter up to the level of the renal pelvis. A rare cause of ureteric stricture, contiguous spread of prostatic adenocarcinoma, should be considered in the differential diagnosis of patients presenting with upper tract obstruction and a known history of prostatic adenocarcinoma. Androgen deprivation therapy for several months did not seem to cause resolution of the tumor in the periureteric, ureteric and perihilar tissues.

  20. Intramucosal adenocarcinoma of the ileum originated 40 years after ileosigmoidostomy

    Full Text Available Abstract Background Small bowel adenocarcinomas (SBAs are rare carcinomas. They are asymptomatic and usually neither endoscopy nor contrast studies are performed for screening Case presentation A 72-year-old Japanese male had a positive fecal occult blood test at a regular check-up in 2006. He suffered appendicitis and received an ileosigmoidostomy in 1966. A colonoscopy revealed an irregular mucosal lesion with an unclear margin at the ileum side of the anastomosis. A mucosal biopsy specimen showed adenocarcinoma histopathologically. Excision of the anastomosis was performed for this patient. The resected specimen showed a flat mucosal lesion with a slight depression at the ileum adjacent to the anastomosis. Histological examination revealed a well differentiated intramucosal adenocarcinoma (adenocarcinoma in situ. Immunohistological staining demonstrated the overexpression of p53 protein in the adenocarcinoma. Conclusion Adenocarcinoma of the ileum at such an early stage is a very rare event. In this case, there is a possibility that the ileosigmoidostomy resulted in a back flow of colonic stool to the ileum that caused the carcinogenesis of the small intestine.
