    2013-01-01

    Cutaneous vulvar carcinomas are predominantly of squamous cell carcinoma type. Primary vulvar adenocarcinomas are rare with a poorly understood histogenesis. They are classified into extramammary Paget’s disease, sweat gland carcinomas, and breast-like adenocarcinomas of the vulva. Adenocarcinomas, originating from Bartholin glands, can also present as vulvar adenocarcinoma. Rare adenocarcinomas with apocrine features have been described in the literature. The origin of these neoplasms from t...

    Full Text Available Cutaneous metastasis in anorectal adenocarcinoma is a rare entity. Here, we report the case of a 40-year-old female who presented with yellowish-brown, irregular, solid, elevated rashes over the pubis with a recent history off palliative colostomy for anorectal adenocarcinoma. Clinically, we suspected metastasis that was proved on biopsy. We report this case due to the rare presenting site (i.e., perineum of a metastatic adenocarcinoma.

    Full Text Available Abstract Hepatoid adenocarcinoma is a rare variant of extrahepatic adenocarcinoma which behaves like hepatocellular carcinoma in morphology and functionality. We present a rare case of hepatoid adenocarcinoma of the gallbladder which invades deeply the liver bed, in a 59-year-old woman. Histologically, most of the mass in the gallbladder was composed of cells with eosinophilic cytoplasm arranged in a trabecular pattern, which resembled hepatocellular carcinoma. The main differential diagnosis was hepatocellular carcinoma with invasion into the gallbladder. The gallbladder origin of the hepatoid adenocarcinoma was verified by the presence of foci of conventional adenocarcinoma, the recognition of high-grade dysplasia in the adjacent epithelium and the absence of cirrhosis.

    The epidemic increase of adenocarcinoma histology accounting for more than 50% of primary lung malignancies and the advent of effective molecular targeted-therapies against specific gene alterations characterizing this tumor type have led to the reconsideration of the pathologic classification of lung cancer. The new 2015 WHO classification provided the basis for a multidisciplinary approach emphasizing the close correlation among clinical, radiologic and molecular characteristics and histopathologic pattern of lung adenocarcinoma. The terms 'bronchioloalveolar carcinoma' and 'mixed adenocarcinoma' have been eliminated, introducing the concepts of 'adenocarcinoma in situ', 'minimally invasive adenocarcinoma' and the use of descriptive predominant patterns in invasive adenocarcinomas (lepidic, acinar, papillary, solid and micropapillary patterns). 'Invasive mucinous adenocarcinoma' is the new definition for mucinous bronchioloalveolar carcinoma, and some variants of invasive adenocarcinoma have been included, namely colloid, enteric and fetal-type adenocarcinomas. A concise update of the immunomorphologic, radiological and molecular characteristics of the different histologic patterns of lung adenocarcinoma is reported here. PMID:26313326

  5. MR findings of metastatic adenocarcinoma and non-adenocarcinoma in the brain

    To evaluate the difference in MR findings of metastatic adenocarcinoma and non-adenocarcinoma of the brain. The study group consisted of 19 patients with metastatic adenocarcinoma and 13 with metastatic non-adenocarcinoma: there were 64 adenocarcinomas and 45 non-adenocarcinomas. On T1WI, the signal intensity of the lesions was hypointense, isointense, and hyperintense in 57.8 %, 39.0%, and 3.2 % of adenocarcinomas: and 84.5%, 13.3%, and 2.2% of non-adenocarcinomas, respectively. On T2WI, signals were hyperintense, isointense, hypointense, and heterogeneous in 67.2%, 10.9%, 17.2%, and 4.7% of adenocarcinomas: and 80%, 0%, 8.9%, and 11.1% of non-adenocarcinomas, respectively. On T2WI, seven of 19 patients with adenocarcinoma and two of 13 with non-adenocarcinoma were either hypo- or isointense relative to the white matter. In the adenocarcinoma group, hypo- or isointensity was screen in four cases of gastrointestinal cancer, two of lung cancer, and one of endometrial cancer: in the non-adenocarcinoma group, this was seen in adenocarcinoma showed hypointensity on T2WI and hyperintensity on T1WI, and this was probably related to the presence of blood products. On histopathology, one case of adenocarcinoma showing hypointensity on T2WI was shown to contain mucin. When brain metastasis shows hypo- or isointensity on T2WI, adenocarcinoma is more likely than non-adenocarcinoma. (author). 14 refs., 4 figs

    2005-06-01

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

  7. IQGAP1 in rectal adenocarcinomas

    Holck, Susanne; Nielsen, Hans Jørgen; Hammer, Emilie;

    2015-01-01

    Treatment of rectal adenocarcinoma includes total mesorectal excision, which is preceded by radiochemotherapy (RCT) in cases of advanced disease. The response to RCT varies from total tumor regression to no effect but this heterogeneous response is unexplained. However, both radiation and treatment...... with 5-fluorouracil may induce treatment resistance through upregulation of the mitogen-activated protein kinase (MAPK) cascade. IQGAP1 is a scaffold protein that appears to be essential to MAPK signaling in cancers. We have therefore studied IQGAP1 protein expression in rectal adenocarcinomas before...

  8. Ampullary adenocarcinoma – differentiation matters

    2008-09-01

    Full Text Available Abstract The periampullary region gives rise to two main subtypes of adenocarcinoma that show either pancreatobiliary or intestinal differentiation. New data demonstrates that the histological subtype – more so than the anatomical location – is an important independent prognostic factor. This fuels the discussion about maintaining ampullary cancer as a separate entity.

    2013-01-01

    Full Text Available Vitiligo is a disease that results in depigmented areas in the skin. It may develop at any age but the average age at onset is 20 years. Association of vitiligo and melanoma has been commonly reported, but malignancies other than melanoma have been rarely associated with vitiligo. We report a 73-year-old patient with new onset vitiligo who developed esophageal adenocarcinoma in the following years.

  11. Advances of Pulmonary Adenocarcinoma with Micropapillary Pattern

    Xiangyu SHI

    2015-11-01

    Full Text Available Lung adenocarcinoma with micropapillary pattern (MPP is a kind of rare high invasive malignant tumor, which has been noticed because of high mortality. In 2011, the new pathological classification of lung adenocarcinoma classify it as an independent pathological type, researches on the individual treatment of the disease had been gradually expanded. Recent studies have demonstrated that lung adenocarcinoma with MPP has obvious heterogeneities in metastasis mechanism, clinical pathology, imageology, therapeusis and prognosis. In this paper, we discuss the progress of metastasis mechanism and clinical relevance in lung adenocarcinoma with MPP.

    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.

    2012-04-01

    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.

    2008-01-01

    Urachal adenocarcinoma arising in the dome of the bladder or at the pre-existing urachal remnant is rare. An early case of urachal cyst harboring adenocarcinoma, clinically diagnosed as ovarian tumor, which was surgically removed with a good prognosis is reported.

  15. Adenocarcinoma of the small bowel

    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)

    2010-06-01

    Full Text Available Context: The most common malignancies associated with malignant pleural effusions are carcinomas of the breast, lung, gastrointestinal tract, ovary and lymphomas. Primary peritoneal adenocarcinoma is a very rare cause of malignant pleural effusion. Case Report: A 72-year old female patient presented to us with shortness of breath for the last 2 months. A contrast-enhanced computed tomography (CECT scan of her-thorax revealed only bilateral pleural effusion with absence of any mass lesion or any mediastinal lymphadenopathy. A cytologic examination of pleural fluid revealed adenocarcinoma cells. A CECT of her abdomen and pelvis revealed heterogenous thickening of omentum with nodular appearances and small amount of ascites. Her ovaries were normal and no other mass lesion was detected. A histological examination of a peritoneal lesion was suggestive of adenocarcinoma. Conclusions: The patient was diagnosed with a rare case of primary peritoneal adenocarcinoma with bilateral pleural effusion.

    Abstract Background Sinonasal adenocarcinomas are uncommon tumors which develop in the ethmoid sinus after exposure to wood dust. Although the etiology of these tumors is well defined, very little is known about their molecular basis and no diagnostic tool exists for their early detection in high-risk workers. Methods To identify genes involved in this disease, we performed gene expression profiling using cancer-dedicated microarrays, on nine matched samples of sinonasal adenocarcinomas and n...

  3. CT findings of adenocarcinoma of the lung

    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

  4. Chemoradiation for adenocarcinoma of the anus

    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

    2010-02-01

    Full Text Available Um bovino Guzerá, fêmea, adulto, com histórico de insuficiência cardíaca congestiva direita de duração de duas semanas, morreu durante o transporte ao hospital veterinário. À necropsia, o lobo pulmonar cranial esquerdo estava moderadamente aumentado de tamanho e firme. O parênquima do lobo afetado era branco e continha múltiplas áreas de 0,3 a 1,5cm de diâmetro, amareladas e caseosas. Alterações semelhantes foram observadas nos linfonodos mediastínicos e brônquicos, no pericárdio parietal, no epicárdio e na adventícia da artéria pulmonar. Histologicamente, a massa tecidual do lobo pulmonar era constituída por células epiteliais neoplásicas de padrão acinar, com duas ou mais camadas celulares, algumas com projeções papilares intraluminais. A anisocariose era acentuada, e o índice mitótico, moderado (dois a três por campo de maior aumento. Envolvendo as neoformações, observava-se abundante tecido conjuntivo fibroso. Focos de necrose e mineralização eram multifocais moderados. Alterações histológicas semelhantes foram observadas nos linfonodos brônquicos, nos mediastínicos, nos pericárdios visceral e parietal e na adventícia da artéria pulmonar. Com exceção do fígado com congestão generalizada crônica, não foram observadas alterações macro e microscópicas em outros órgãos. Os achados histológicos foram compatíveis com adenocarcinoma pulmonar, com metástases regionais. O quadro de insuficiência cardíaca congestiva direita provavelmente foi decorrente do impedimento da drenagem linfática pelas metástases.An adult Guzera cow, dysplaying for two weeks signs of right-sided congestive heart failure died during the transport to the veterinary hospital. At necropsy, the left cranial lung lobe was moderately increased in volume and firm.

  6. 2011 New lung adenocarcinoma multidisciplinary classification: imaging aspects

    The new classification of lung adenocarcinoma has been proposed by International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society in 2011. This new classification proposes a series of new concepts, such as lung adenocarcinoma in situ replacing the old term bronchioloalveolar carcinoma, minimally invasive adenocarcinoma and subtypes of invasive adenocarcinoma. This paper reviews the major advances of this new classification and its effect on imaging evaluation of lung adenocarcinoma and CT appearances of various subtypes of lung adenocarcinoma. (authors)

    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%.

    Adenocarcinoma is a type of cancer that occurs in the glandular cells throughout the body. There are several metastatic adenocarcinoma of unknown primary origin. Currently, there is no highly effective method to differentiate pancreatic ductal adenocarcinoma (PDAC) from other adenocarcinomas. Here, we identified pancreas tissue by site-specific methylation at FRY and found that it can also detect PDAC. The establishment of Combined Bisulphite Restriction Analysis (COBRA) and quantitative real-time PCR techniques of FRY revealed FRY hypermethylation in 21 out of 24 normal pancreatic tissue samples, whereas all other normal tissue samples from thirteen other organs (80 samples) remained totally unmethylated. Similarly in application to PDAC, this marker effectively indicated 25 PDAC among 151 other common adenocarcinomas with values of 100%, 98.7%, 92.6%, and 100% in sensitivity, specificity, positive predictive value and negative predictive value, respectively. In summary, we have demonstrated that this epigenetic site-specific marker has high potential for pancreatic tissue identification and can be applied in PDAC diagnosis. PMID:26990916

    Marcos Félix Osorio Pagola

    2010-12-01

    Full Text Available The case of a 68 years old patient, smoking since adolescence, with urban origins, obesity history and gastroesophageal reflux symptoms is presented. The patient was diagnosed with gastroesophageal junction adenocarcinoma type III in the Gastroenterology Department of the Provincial University Hospital of Cienfuegos where he arrived with weight loss of about 20 pounds in four months along with dyspeptic manifestations such as stomach acidity, slow digestion, bloating and epigastric pain unrelated to food consumption. No dysphagia was observed as presentation form of the disease. The patient underwent surgery and chemotherapy and has had a favourable outcome up until today. It was decided to publish this article because of the few cases of gastroesophageal junction adenocarcinoma and especially type III that are commonly presented and also because the diagnosis is, unlike this case, usually made at an advanced stage of the disease

    2005-01-01

    Malignant extragonadal tumors arising from endometriosis are rare. We report on two cases. A 41-year-old gravida 1, para 1 (G1P1), with adenocarcinoma of the right parametrium arising from endometriosis and a 51-year-old G1P1 with endometriosis-associated rectovaginal adenocarcinoma were treated. Treatment included radical surgery plus radiation therapy. While the former patient was doing well 2 years after the primary diagnosis, the latter suffered a local pelvic recurrence 2 years later. Although there are no randomized controlled studies, radical surgery followed by radiation therapy seems generally to be the treatment of choice. The analysis of PTEN in various forms of endometriosis and its malignant transformation may help in understanding the early steps of tumorigenesis. PMID:16343215

    2009-01-01

    Ampullary carcinoma is the second most common cancer of the peri-ampullary area after pancreatic carcinoma and metastasizes mostly intra-abdominally and to the liver. Extra-abdominal metastases are less frequent. In this report we describe the case of a patient with resected adenocarcinoma of the ampulla of Vater who developed skeletal metastases in the lower extremity and brain metastases. We briefly discuss aspects of this comparatively rare gastrointestinal malignancy.

  18. Choroidal and cutaneous metastasis from gastric adenocarcinoma

    2013-01-01

    Choroidal or cutaneous metastasis of gastric cancer is rare. Gastrointestinal cancer was found in only 4% in patients with uveal metastasis. Choroidal metastasis from gastric cancer was reported in two cases in earlier literature. The frequency of gastric cancer as a primary lesion was 6% in cutaneous metastasis of men, and cutaneous metastasis occurs in 0.8% of all gastric cancers. We report a patient with gastric adenocarcinoma who presented with visual disorder in his left eye and skin pai...

    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 ...

  20. Diffuse pancreatic ductal adenocarcinoma: Characteristic imaging features

    Purpose: To evaluate imaging findings of diffuse pancreatic ductal adenocarcinoma. Materials and methods: We included 14 patients (4 men and 10 women; mean age, 64.5 years) with diffuse pancreatic ductal adenocarcinoma on the basis of retrospective radiological review. Two radiologists retrospectively reviewed 14 CT scans in consensus with respect to the following: tumor site, peripheral capsule-like structure, dilatation of intratumoral pancreatic duct, parenchymal atrophy, and ancillary findings. Eight magnetic resonance (MR) examinations with MR cholangiopancreatography (MRCP) and seven endoscopic retrograde cholangiopancreatography (ERCP) were also reviewed, focusing on peripheral capsule-like structure and dilatation of intratumoral pancreatic duct. Results: CT revealed tumor localization to the body and tail in 11 (79%) patients and peripheral capsule-like structure in 13 (93%). The intratumoral pancreatic duct was not visible in 13 (93%). Pancreatic parenchymal atrophy was not present in all 14 patients. Tumor invasion of vessels was observed in all 14 patients and of neighbor organs in 8 (57%). On contrast-enhanced T1-weighted MR images, peripheral capsule-like structure showed higher signal intensity in five patients (71%). In all 11 patients with MRCP and/or ERCP, the intratumoral pancreatic duct was not dilated. Conclusion: Diffuse pancreatic ductal adenocarcinoma has characteristic imaging findings, including peripheral capsule-like structure, local invasiveness, and absence of both dilatation of intratumoral pancreatic duct and parenchymal atrophy

  1. [Ductal adenocarcinoma and unusual differential diagnosis].

    Haage, P; Schwartz, C A; Scharwächter, C

    2016-04-01

    Ductal pancreatic adenocarcinoma is by far the most common solid tumor of the pancreas. It has a very poor prognosis, especially in the more advanced stages which are no longer locally confined. Due to mostly unspecific symptoms, imaging is key in the diagnostic process. Because of the widespread use of imaging techniques, incidental findings are to a greater extent discovered in the pancreas, which subsequently entail further work-up. Ductal pancreatic adenocarcinoma can be mimicked by a large number of different lesions, such as anatomical variants, peripancreatic structures and tumors, rarer primary solid pancreatic tumors, cystic tumors, metastases or different variants of pancreatitis. Additionally, a number of precursor lesions can be differentiated. The correct classification is thus important as an early diagnosis of ductal pancreatic adenocarcinoma is relevant for the prognosis and because the possibly avoidable treatment is very invasive. All major imaging techniques are principally suitable for pancreatic imaging. In addition to sonography of the abdomen, usually the baseline diagnostic tool, computed tomography (CT) with its superior spatial resolution, magnetic resonance imaging (MRI) with its good soft tissue differentiation capabilities, possibly in combination with MR cholangiopancreatography (MRCP), endosonography with its extraordinary spatial resolution, conceivably with additional endoscopic retrograde CP or the option of direct biopsy and finally positron emission tomography CT (PET-CT) as a molecular imaging tool are all particularly useful modalities. The various techniques all have its advantages and disadvantages; depending on the individual situation they may need to be combined. PMID:27000276

  2. Gene expression profiling in sinonasal adenocarcinoma

    Sébille-Rivain Véronique

    2009-11-01

    Full Text Available Abstract Background Sinonasal adenocarcinomas are uncommon tumors which develop in the ethmoid sinus after exposure to wood dust. Although the etiology of these tumors is well defined, very little is known about their molecular basis and no diagnostic tool exists for their early detection in high-risk workers. Methods To identify genes involved in this disease, we performed gene expression profiling using cancer-dedicated microarrays, on nine matched samples of sinonasal adenocarcinomas and non-tumor sinusal tissue. Microarray results were validated by quantitative RT-PCR and immunohistochemistry on two additional sets of tumors. Results Among the genes with significant differential expression we selected LGALS4, ACS5, CLU, SRI and CCT5 for further exploration. The overexpression of LGALS4, ACS5, SRI, CCT5 and the downregulation of CLU were confirmed by quantitative RT-PCR. Immunohistochemistry was performed for LGALS4 (Galectin 4, ACS5 (Acyl-CoA synthetase and CLU (Clusterin proteins: LGALS4 was highly up-regulated, particularly in the most differentiated tumors, while CLU was lost in all tumors. The expression of ACS5, was more heterogeneous and no correlation was observed with the tumor type. Conclusion Within our microarray study in sinonasal adenocarcinoma we identified two proteins, LGALS4 and CLU, that were significantly differentially expressed in tumors compared to normal tissue. A further evaluation on a new set of tissues, including precancerous stages and low grade tumors, is necessary to evaluate the possibility of using them as diagnostic markers.

    Chen, Michelle M; Roman, Sanziana A; Sosa, Julie A; Judson, Benjamin L

    2015-06-01

    Objectives To identify factors associated with disease-specific survival (DSS) in intestinal and nonintestinal sinonasal adenocarcinoma. Design Retrospective review. Setting Surveillance Epidemiology and End Results database. Participants Adult patients with sinonasal adenocarcinoma. Main Outcome Measures DSS. Results We identified 325 patients; of these, 300 had the nonintestinal type and 25 had intestinal type histologies. The 5-year DSS rates for patients who had no treatment, radiation (RT), surgery, and surgery and postoperative RT were 42.5, 46.1, 85.6, and 72.6%, respectively (log-rank test; p Black race, age ≥ 75 years, paranasal sinus involvement, and high grade were independently associated with decreased DSS. Compared with RT, surgery (hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.15-0.77), and adjuvant RT (HR: 0.47; 95% CI, 0.26-0.86) were associated with improved DSS. Conclusions There is no difference in prognosis between intestinal and nonintestinal subtypes of sinonasal adenocarcinoma. Treatment with surgery alone or adjuvant RT is associated with a more favorable prognosis. PMID:26225303

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. Mucinous ovarian adenocarcinomas cannot......, carcinoembryonic antigen, and cytokeratins 7 and 20 to detect tumor-associated glycoproteins and keratin proteins in ovarian and colonic carcinomas. 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...

    Hamilton Petry de Souza

    1999-04-01

    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.

    2009-01-01

    We report a case of gastric choriocarcinoma admixed with an α-fetoprotein (AFP)-producing adenocarcinoma .A 70-year-old man was hospitalized for gastric cancer that was detected during screening by esophagogastroduodenoscopy (EGD). Initial laboratory data showed the increased serum level of AFP and EGD revealed a 5-cm ulcerofungating mass in the greater curvature of the gastric antrum.The patient underwent radical subtotal gastrectomy with D2 lymph node dissection and Billroth Ⅱ gastrojejunostomy. Histopathological evaluation confirmed double primary gastric cancer: gastric choriocarcinoma admixed with an AFP-producing adenocarcinoma and separated adenocarcinoma. At 2 wk postoperatively, his human chorionic gonadotropin and AFP levels had reduced and six cycles of adjuvant chemotherapy were initiated. No recurrence or distant metastasis was observed at 4 years postoperatively.

  8. Association of visceral adiposity with oesophageal and junctional adenocarcinomas.

    Beddy, P

    2012-02-01

    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.

  9. Prostatic adenocarcinoma with and without metastasis to bone in dogs

    The signalment, clinical signs, and histologic tumor pattern were compared retrospectively in 12 dogs having primary prostatic adenocarcinoma with (5 cases) and without metastasis (7 cases) to bone. Weight loss and lumbar pain were observed more frequently in dogs having prostatic adenocarcinoma with metastasis to bone. A distinctive histologic pattern was not associated with prostatic adenocarcinoma that had metastasized to bone. The alveolar papillary pattern was the predominant histologic type observed in both groups. Metastasis to extra pelvic bony sites included the scapulas, ribs, and digits. The results of this study indicate that skeletal metastasis was not uncommon in dogs having prostatic adenocarcinoma

  18. Intensity-Modulated Radiotherapy for Pancreatic Adenocarcinoma

    Purpose: To report the outcomes and toxicities in patients treated with intensity-modulated radiotherapy (IMRT) for pancreatic adenocarcinoma. Methods and Materials: Forty-seven patients with pancreatic adenocarcinoma were treated with IMRT between 2003 and 2008. Of these 47 patients, 29 were treated adjuvantly and 18 definitively. All received concurrent 5-fluorouracil chemotherapy. The treatment plans were optimized such that 95% of the planning target volume received the prescription dose. The median delivered dose for the adjuvant and definitive patients was 50.4 and 54.0 Gy, respectively. Results: The median age at diagnosis was 63.9 years. For adjuvant patients, the 1- and 2-year overall survival rate was 79% and 40%, respectively. The 1- and 2-year recurrence-free survival rate was 58% and 17%, respectively. The local-regional control rate at 1 and 2 years was 92% and 80%, respectively. For definitive patients, the 1-year overall survival, recurrence-free survival, and local-regional control rate was 24%, 16%, and 64%, respectively. Four patients developed Grade 3 or greater acute toxicity (9%) and four developed Grade 3 late toxicity (9%). Conclusions: Survival for patients with pancreatic cancer remains poor. A small percentage of adjuvant patients have durable disease control, and with improved therapies, this proportion will increase. Systemic therapy offers the greatest opportunity. The present results have demonstrated that IMRT is well tolerated. Compared with those who received three-dimensional conformal radiotherapy in previously reported prospective clinical trials, patients with pancreatic adenocarcinoma treated with IMRT in our series had improved acute toxicity.

  1. Duodenal Adenocarcinoma Metastatic to the Breast: A Case Report.

    Yu, Haibo; Song, Hongliang; Jiang, Yi

    2016-03-01

    Duodenal adenocarcinoma, a very rare malignant gastrointestinal tumor, mainly metastasizes via the lymphatic system. Metastases from duodenal adenocarcinomas to the breast are very uncommon.A 31-year-old woman presented at our department with a left breast tumor. She had a past medical history of duodenal adenocarcinoma. Physical examination on admission confirmed a 2.5-cm-diameter tumor in the outer lower quadrant of the left breast. Computed tomography (CT) examination showed a soft lesion with tissue-like density and enlarged axillary lymph nodes. Local excision was performed to remove the breast lesion. The findings of cytologic, histologic, and immunohistochemistry examination indicated a breast metastasis from the previous duodenal adenocarcinoma. The patient was treated with palliative chemotherapy.Metastases from duodenal adenocarcinoma to the breast are rare. The diagnosis depends on medical history, imaging, and pathologic examination including immunohistochemistry. An accurate diagnosis is important to avoid unnecessary surgery. PMID:26986146

  4. Expression of p53 protein in Barrett’s adenocarcinoma and adenocarcinoma of the gastric cardia and antrum

    Jovanović Ivan

    2005-01-01

    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.

    Choi, Jin Woo [School of Dentistry, Seoul National University, Seoul (Korea, Republic of)

    2010-12-15

    Cyst adenocarcinoma of the salivary glands is a very rare, slow growing, and low-grade malignant neoplasm. It is characterized by predominantly cystic growth with or without the intraluminal papillary component. However, it lacks of any additional specific histopathologic features that characterize other types of salivary carcinomas showing cystic growth. Therefore, definite diagnosis of the cyst adenocarcinoma is difficult and it is often misdiagnosed. It is conceptually the malignant counterpart of the benign cyst adenoma. We present a cyst adenocarcinoma on the palate of a 49-year-old man with special emphasis on magnetic resonance imaging.

    Full Text Available Abstract Purpose To analyze the outcomes of patients from a single institution treated with surgery and orthovoltage intraoperative radiotherapy (IORT for pancreatic adenocarcinoma. Methods We retrospectively reviewed 23 consecutive patients from 1990-2001 treated with IORT to 23 discrete sites with median and mean follow up of 6.5 and 21 months, respectively. Most tumors were located in the head of the pancreas (83% and sites irradiated included: tumor bed (57%, vessels (26%, both the tumor bed/vessels (13% and other (4%. The majority of patients (83% had IORT at the time of their definitive surgery. Three patients had preoperative chemoradiation (13%. Orthovoltage X-rays (200-250 kVp were employed via individually sized and beveled cone applicators. Additional mean clinical characteristics include: age 64 (range 41-81; tumor size 4 cm (range 1.4-11; and IORT dose 1106 cGy (range 600-1500. Post-operative external beam radiation (EBRT or chemotherapy was given to 65% and 76% of the assessable patients, respectively. Outcomes measured were infield control (IFC, loco-regional control (LRC, distant metastasis free survival (DMFS, overall survival (OS and treatment-related complications. Results Kaplan-Meier (KM 2-year IFC, LRC, DMFS and OS probabilities for the whole group were 83%, 61%, 26%, and 27%, respectively. Our cohort had three grade 3-5 complications associated with treatment (surgery and IORT. Conclusions Orthovoltage IORT following tumor reductive surgery is reasonably well tolerated and seems to confer in-field control in carefully selected patients. However, distant metastases remain the major problem for patients with pancreatic adenocarcinoma.

  11. Estrogen, male dominance and esophageal adenocarcinoma: Is there a link?

    Huiqi Yang; Olga A Sukocheva; Damian J Hussey; David I Watson

    2012-01-01

    Esophageal adenocarcinoma is a cancer with poor prognosis, and its incidence has risen sharply over recent decades. Obesity is a major risk factor for developing this cancer and there is a clear male gender bias in the incidence that cannot be fully explained by known risk factors. It is possible that a difference in the expression of estrogen, or its signaling axes, may contribute to this gender bias. We undertook a comprehensive literature search and analyzed the available data regarding estrogen and estrogen receptor expression, and the possible sex-specific links with esophageal adenocarcinoma development. Potentially relevant associations between visceral vs subcutaneous fat deposition and estrogen expression, and the effect of crosstalk between estrogen and leptin signaling were identified. We also found limited studies suggesting a role for estrogen receptor β expression in esophageal adenocarcinoma development. The current literature supports speculation on an etiological role for estrogen in the male gender bias in esophageal adenocarcinoma, but further studies are required.

    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.

    Although embryonal proteins have been used as tumor marker, most are not useful for detection of early malignancy. In the present study, we developed mouse monoclonal antibodies against fetal lung of miniature swine, and screened them to find an embryonal protein that is produced at the early stage of malignancy, focusing on lung adenocarcinoma. We found an antibody clone that specifically stained stroma of lung adenocarcinoma. LC-MS/MS identified the protein recognized by this clone as dimet...

  16. Pancreatic Head Adenocarcinomas - Histopathologic Evaluation and Prognostic Factors

    2014-01-01

    Primary adenocarcinomas located in the pancreatic head may arise from the distal bile duct, the ampulla, the periampullary duodenum, and the pancreatic tissue itself. These tumours are distinct cancer entities whose pathobiology, staging, and clinical course have unique features. The aims of the present study were to investigate how the standardized histopathological examination protocol ensures correct classification of tumour origin of pancreatic head adenocarcinomas. Furthermore, we exa...

  17. Multiple urinary bladder masses from metastatic prostate adenocarcinoma

    Richard Choo

    2010-12-01

    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.

    Ovarian endometriosis can transform into malignant tumors, and ovarian carcinomas relatively frequently contain foci of endometriosis. In this study, the author reviewed 15 cases of endometrioid adenocarcinoma of the ovary in the last 15 years of our pathology laboratory in search for the presence of endometriosis within the tumor. Six (40%) of the 15 endometrioid adenocarcinoma were found to have endometriosis in the tumor. All of the endometriosis were atypical. The age of the 6 patients ra...

  19. Synchronous Collision Neuroendocrine Tumor and Rectal Adenocarcinoma: a Case Report

    Zhu, Jie-gao; Zhang, Zhong-Tao; WU, GUO-CONG; Han, Wei; Wang, Kang-Li

    2015-01-01

    Collision tumors are thought to arise from the accidental meeting of two independent tumors. Adenocarcinoma is the most common malignant rectal tumor, while neuroendocrine tumor (NET) is relatively rare. Due to the endoscopy and reporting, the overall incidence of NETs was increasing recently but still less than 1 per 100,000. This means that a combination of an adenocarcinoma and NET is a very rare finding and an actual collision of these tumors even more so. We report here a highly unusual ...

  20. Curative surgical management of isolated adrenal recurrence of oesophageal adenocarcinoma.

    O'Sullivan, K E

    2013-01-01

    Adrenal metastases of oesophageal adenocarcinoma are rarely detected in the clinical setting, more frequently being found as an incidental postmortem finding in the presence of widespread metastases. With improvements in the sensitivity of radiological diagnostic modalities, the incidence of adrenal tumour detection is on the rise. We report herein a particularly rare case of primary operative management by adrenalectomy for an isolated right-sided adrenal metastasis secondary to oesophageal adenocarcinoma, with a long-term survival.

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

    2009-04-01

    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.

    2012-05-01

    Full Text Available Objective: Prostate cancer is the second most common cause of male cancer deaths after lung cancer in developed countries. The prognostic factors currently identified for prostate carcinoma include preoperative serum PSA, TNM staging system, histological grade and surgical margin status and are composed of the clinically most important and useful parameters. However, all the markers studied have not been applied in clinical practice. The oncofetal protein Insulin-Like Growth Factor II has been demonstrated to be associated with aggressive tumor behavior in many organs including urothelial tumors and renal cell carcinoma. Our aim was to investigate the expression status of Insulin-Like Growth Factor II in benign prostate glands, high grade PIN and prostate adenocarcinoma, and to determine the role of Insulin-Like Growth Factor II in pathogenesis of prostate adenocarcinoma.Material and Method: A total of 70 prostate adenocarcinoma cases accompanied by high grade PIN and benign prostate glands were evaluated by immunohistochemistry for the expression of Insulin-Like Growth Factor II.Results: Insulin-Like Growth Factor II expression was not seen in any of the 70 prostate adenocarcinoma and high grade PIN cases and benign prostate glands.Conclusion: Although the number of our cases was limited, our results suggested that Insulin-Like Growth Factor II protein expression was not included in the pathogenesis of the prostate adenocarcinomas and Insulin-Like Growth Factor II expression status cannot be used for diagnosis of prostate adenocarcinomas.

The patient was a 73-year-old man who had had a nodule on the left lower eyelid for two years. He was referred to our hospital with a diagnosis of a swollen chalazion. The clinical and histopathological records were reviewed and the mass was excised. Histopathological examination revealed a mucinous sweat gland adenocarcinoma. Postoperative magnetic resonance imaging and positron emission tomography excluded systemic metastases. After the histopathological findings, a complete surgical excision of the margins of the adenocarcinoma was performed, with histopathological confirmation of negative margins. After the final histopathological examination, the patient was diagnosed with a primary mucinous sweat gland adenocarcinoma of the left eyelid. Six months after the surgery, no recurrence has been observed. Because the appearance of mucinous sweat gland adenocarcinoma of the eyelid is quite variable, the final diagnosis can only be made by histopathological examination. A complete surgical excision is recommended.Keywords: complete surgical excision, eyelid, initial stage, mucinous sweat gland adenocarcinoma

  4. Improved Pancreatic Adenocarcinoma Diagnosis in Jaundiced and Non-Jaundiced Pancreatic Adenocarcinoma Patients through the Combination of Routine Clinical Markers Associated to Pancreatic Adenocarcinoma Pathophysiology.

    María José Ferri

    Full Text Available There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma. Carbohydrate antigen 19-9 (CA 19-9 is a tumor marker only recommended for pancreatic adenocarcinoma follow-up. One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis. In this study we will assess the value of panels of serum molecules related to pancreatic cancer physiopathology to determine whether alone or in combination could help to discriminate between these two pathologies.CA 19-9, carcinoembryonic antigen (CEA, C-reactive protein, albumin, insulin growth factor-1 (IGF-1 and IGF binding protein-3 were measured using routine clinical analyzers in a cohort of 47 pancreatic adenocarcinoma, 20 chronic pancreatitis and 15 healthy controls.The combination of CA 19-9, IGF-1 and albumin resulted in a combined area under the curve (AUC of 0.959 with 93.6% sensitivity and 95% specificity, much higher than CA 19-9 alone. An algorithm was defined to classify the patients as chronic pancreatitis or pancreatic cancer with the above specificity and sensitivity. In an independent validation group of 20 pancreatic adenocarcinoma and 13 chronic pancreatitis patients, the combination of the four molecules classified correctly all pancreatic adenocarcinoma and 12 out of 13 chronic pancreatitis patients.Although this panel of markers should be validated in larger cohorts, the high sensitivity and specificity values and the convenience to measure these parameters in clinical laboratories shows great promise for improving pancreatic adenocarcinoma diagnosis.

  5. The Male Predominance in Esophageal Adenocarcinoma.

    Xie, Shao-Hua; Lagergren, Jesper

    2016-03-01

    The incidence of esophageal adenocarcinoma (EAC) has increased rapidly during the past 4 decades in many Western populations, including North America and Europe. The established etiological factors for EAC include gastroesophageal reflux and obesity, Helicobacter pylori infection, tobacco smoking, and consumption of fruit and vegetables. There is a marked male predominance of EAC with a male-to-female ratio in incidence of up to 9:1. This review evaluates the available literature on the reasons for the male predominance, particularly an update on epidemiologic evidence from human studies during the past decade. The striking sex difference does not seem to be explained by established risk factors, given that the prevalence of the etiological factors and the strengths of associations between these factors and EAC risk are similar between the sexes. Sex hormonal factors may play a role in the development of EAC; estrogenic exposures may prevent such development, whereas androgens might increase the risk of EAC. However, continuing research efforts are still needed to fully understand the reasons for the male predominance of EAC. PMID:26484704

    2011-01-01

    Ductal adenocarcinoma of the pancreas is a lethal cancer for which the only chance of long-term survival belongs to the patient with localized disease in whom a potentially curative resection can be done.Therefore,biomarkers for early detection and new therapeutic strategies are urgently needed.miRNAs are a recently discovered class of small endogenous non-coding RNAs of about 22 nucleotides that have gained attention for their role in downregulation of mRNA expression at the posttranscriptional level.miRNAs regulate proteins involved in critical cellular processes such as differentiation,proliferation,and apoptosis.Evidence suggests that deregulated miRNA expression is involved in carcinogenesis at many sites,including the pancreas.Aberrant expression of miRNAs may upregulate the expression of oncogenes or downregulate the expression of tumor suppressor genes,as well as play a role in other mechanisms of carcinogenesis.The purpose of this review is to summarize our knowledge of deregulated miRNA expression in pancreatic cancer and discuss the implication for potential translation of this knowledge into clinical practice.

    Gastric cancer is a leading cause of cancer deaths, but analysis of its molecular and clinical characteristics has been complicated by histological and aetiological heterogeneity. Here we describe a comprehensive molecular evaluation of 295 primary gastric adenocarcinomas as part of The Cancer Genome Atlas (TCGA) project. We propose a molecular classification dividing gastric cancer into four subtypes: tumours positive for Epstein–Barr virus, which display recurrent PIK3CA mutations, extreme DNA hypermethylation, and amplification of JAK2, CD274 (also known as PD-L1) and PDCD1LG2 (also knownasPD-L2); microsatellite unstable tumours, which show elevated mutation rates, including mutations of genes encoding targetable oncogenic signalling proteins; genomically stable tumours, which are enriched for the diffuse histological variant and mutations of RHOA or fusions involving RHO-family GTPase-activating proteins; and tumours with chromosomal instability, which show marked aneuploidy and focal amplification of receptor tyrosine kinases. Identification of these subtypes provides a roadmap for patient stratification and trials of targeted therapies. PMID:25079317

    Hepatoid adenocarcinoma (HAC) is a rare neoplasm with aberrant hepatocellular differentiation. HAC occurs in extrahepatic organs such as the gastrointestinal tract, testes, ovaries, and lungs and frequently produces alpha-fetoprotein. A 69-year-old patient was diagnosed clinically with T2aN0M0, stage IB, non-small cell lung carcinoma. Because the tumor showed tight adhesion to the chest wall, we performed left upper lobectomy, combined resection of the 3rd and 4th ribs, and lymph node dissection. Pathological examination confirmed the diagnosis of HAC of the lung (pathological T2aN0M0, stage IB), and four courses of cisplatin and gemcitabine were administered as adjuvant chemotherapy. Genetic analysis of the epidermal growth factor receptor showed wild type. Preoperative serum alpha-fetoprotein level, a useful marker of disease progression, was elevated to 4497 ng/ml, decreasing within the normal range by about 3 months postoperatively. The patient remains alive without recurrence as of 51 months after surgery. PMID:26943677

  9. Distal Esophageal Adenocarcinoma and Gastric Adenocarcinoma: Time for a Shared Research Agenda.

    Jansen, Marnix; Wright, Nicholas A

    2016-01-01

    The key insight that sparked Darwin's theory of descent with modification was that he compared and contrasted differences between living and extinct species across time and space. He likely arrived on this theory in large part through his culinary experiences, set against the background of the rugged Patagonian landscape of Southern Argentina. We feel that further integration of research into gastric and esophageal adenocarcinoma may benefit both fields and similarly lead to a coherent understanding of cancer progression in the upper gastrointestinal tract across time and space. Although the environmental trigger differs between carcinogenesis of the stomach and distal esophagus, there remain many important lessons to be learned from comparing precursor stages, such as intestinal metaplasia, across anatomic borders. This analysis will absolutely require detailed sampling within and between these related species, but most importantly we need higher resolution clinical phenotyping to relate genomic differences to drivers of morphologic evolution. In the end, this may provide us with a new phylogeny showing key differences between esophageal and gastric adenocarcinoma. PMID:27573764

  10. New Morphological Features for Grading Pancreatic Ductal Adenocarcinomas

    2013-01-01

    Full Text Available Pathological diagnosis is influenced by subjective factors such as the individual experience and knowledge of doctors. Therefore, it may be interpreted in different ways for the same symptoms. The appearance of digital pathology has created good foundation for objective diagnoses based on quantitative feature analysis. Recently, numerous studies are being done to develop automated diagnosis based on the digital pathology. But there are as of yet no general automated methods for pathological diagnosis due to its specific nature. Therefore, specific methods according to a type of disease and a lesion could be designed. This study proposes quantitative features that are designed to diagnose pancreatic ductal adenocarcinomas. In the diagnosis of pancreatic ductal adenocarcinomas, the region of interest is a duct that consists of lumen and epithelium. Therefore, we first segment the lumen and epithelial nuclei from a tissue image. Then, we extract the specific features to diagnose the pancreatic ductal adenocarcinoma from the segmented objects. The experiment evaluated the classification performance of the SVM learned by the proposed features. The results showed an accuracy of 94.38% in the experiment distinguishing between pancreatic ductal adenocarcinomas and normal tissue and a classification accuracy of 77.03% distinguishing between the stages of pancreatic ductal adenocarcinomas.

    Full Text Available Abstract Background The aim of this study is to review all features of incidentally discovered prostate adenocarcinoma in patients undergoing radical cystoprostatectomy for bladder cancer. Methods The medical charts of 300 male patients who underwent radical cystoprostatectomy for bladder cancer between 1997 and 2005 were retrospectively reviewed. The mean age of the patients was 62 (range 51-75 years. Results Prostate adenocarcinoma was present in 60 (20% of 300 specimens. All were acinar adenocarcinoma. Of these, 40 (66.7% were located in peripheral zone, 20 (33.3% had pT2a tumor, 12 (20% had pT2b tumor, 22(36.7% had pT2c and, 6 (10% had pT3a tumor. Gleason score was 6 or less in 48 (80% patients. Surgical margins were negative in 54 (90% patients, and tumor volume was less than 0.5 cc in 23 (38.3% patients. Of the 60 incidentally detected cases of prostate adenocarcinoma 40 (66.7% were considered clinically significant. Conclusion Incidentally detected prostate adenocarcinoma is frequently observed in radical cystoprostatectomy specimens. The majority are clinically significant.

  12. Molecular mechanisms of bortezomib resistant adenocarcinoma cells.

    Erika Suzuki

    Full Text Available Bortezomib (Velcade™ is a reversible proteasome inhibitor that is approved for the treatment of multiple myeloma (MM. Despite its demonstrated clinical success, some patients are deprived of treatment due to primary refractoriness or development of resistance during therapy. To investigate the role of the duration of proteasome inhibition in the anti-tumor response of bortezomib, we established clonal isolates of HT-29 adenocarcinoma cells adapted to continuous exposure of bortezomib. These cells were ~30-fold resistant to bortezomib. Two novel and distinct mutations in the β5 subunit, Cys63Phe, located distal to the binding site in a helix critical for drug binding, and Arg24Cys, found in the propeptide region were found in all resistant clones. The latter mutation is a natural variant found to be elevated in frequency in patients with MM. Proteasome activity and levels of both the constitutive and immunoproteasome were increased in resistant cells, which correlated to an increase in subunit gene expression. These changes correlated with a more rapid recovery of proteasome activity following brief exposure to bortezomib. Increased recovery rate was not due to increased proteasome turnover as similar findings were seen in cells co-treated with cycloheximide. When we exposed resistant cells to the irreversible proteasome inhibitor carfilzomib we noted a slower rate of recovery of proteasome activity as compared to bortezomib in both parental and resistant cells. Importantly, carfilzomib maintained its cytotoxic potential in the bortezomib resistant cell lines. Therefore, resistance to bortezomib, can be overcome with irreversible inhibitors, suggesting prolonged proteasome inhibition induces a more potent anti-tumor response.

  13. Lymphatic channel density in colorectal adenocarcinoma

    2010-01-01

    Full Text Available Aims : The purpose of this study was to count the number of lymphatic channels present in colorectal adenocarcinoma and correlate it with site, size, and stage of tumor, lymph node metastasis. Material and Methods: A total of 29 cases of colorectal carcinomas were retrieved from the archives of the pathology department, School of Medical Sciences. One paraffin block containing tumor was selected from each case. Sections of three to five micron thickness were cut from this paraffin block and stained using the monoclonal antibody D2-40[DAKO] specifically to stain lymphatic channel endothelium in normal and neoplastic tissue. The highest number of lymphatic channels in an area of 0.196mm 2 [high power field] was counted in each tumor using NIKON microscope. These findings were correlated with the clinical parameters and also with lymph node metastasis. Statistical software used: SPSS version 11. Results : The highest density of lymphatic channels in colorectal carcinoma was counted after identifying the appropriate "hot spot". The lymphatic channel density was in the range of 15 - 50/ 0.196 mm 2 [high power field]. There was poor association of this lymphatic channel density with site, size, and stage of tumor and also with lymph node metastasis. This result is in concordance with results of studies done elsewhere. Conclusion : In this study no significant association was seen between lymphatic channel density and site, size, stage and lymph node metastasis in colorectal carcinoma. This indicates that lymphatic channel proliferation does not influence tumor aggressiveness. Further studies are needed to validate our findings.

  14. Pathophysiological mechanisms linking obesity and esophageal adenocarcinoma

    Leo; Alexandre; Elizabeth; Long; Ian; LP; Beales

    2014-01-01

    In recent decades there has been a dramatic rise in the incidence of esophageal adenocarcinoma(EAC) in the developed world. Over approximately the same period there has also been an increase in the prevalence of obesity. Obesity, especially visceral obesity, is an important independent risk factor for the development of gastro-esophageal reflux disease, Barrett’s esophagus and EAC. Although the simplest explanation is that this mediated by the mechanical effects of abdominal obesity promoting gastro-esophageal reflux, the epidemiological data suggest that the EAC-promoting effects are independent of reflux. Several, not mutually exclusive, mechanisms have been implicated, which may have different effects at various points along the refluxBarrett’s-cancer pathway. These mechanisms include a reduction in the prevalence of Helicobacter pylori infection enhancing gastric acidity and possibly appetite byincreasing gastric ghrelin secretion, induction of both low-grade systemic inflammation by factors secreted by adipose tissue and the metabolic syndrome with insulin-resistance. Obesity is associated with enhanced secretion of leptin and decreased secretion of adiponectin from adipose tissue and both increased leptin and decreased adiponectin have been shown to be independent risk factors for progression to EAC. Leptin and adiponectin have a set of mutually antagonistic actions on Barrett’s cells which appear to influence the progression of malignant behaviour. At present no drugs are of proven benefit to prevent obesity associated EAC. Roux-en-Y reconstruction is the preferred bariatric surgical option for weight loss in patients with reflux. Statins and aspirin may have chemopreventative effects and are indicated for their circulatory benefits.

  15. Adenocarcinoma of the ethmoid following radiotherapy for bilateral retinoblastoma

    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

  16. Common activation of canonical Wnt signaling in pancreatic adenocarcinoma.

    Marina Pasca di Magliano

    Full Text Available Pancreatic ductal adenocarcinoma (PDA is an extremely aggressive malignancy, which carries a dismal prognosis. Activating mutations of the Kras gene are common to the vast majority of human PDA. In addition, recent studies have demonstrated that embryonic signaling pathway such as Hedgehog and Notch are inappropriately upregulated in this disease. The role of another embryonic signaling pathway, namely the canonical Wnt cascade, is still controversial. Here, we use gene array analysis as a platform to demonstrate general activation of the canonical arm of the Wnt pathway in human PDA. Furthermore, we provide evidence for Wnt activation in mouse models of pancreatic cancer. Our results also indicate that Wnt signaling might be activated downstream of Hedgehog signaling, which is an early event in PDA evolution. Wnt inhibition blocked proliferation and induced apoptosis of cultured adenocarcinoma cells, thereby providing evidence to support the development of novel therapeutical strategies for Wnt inhibition in pancreatic adenocarcinoma.

    Breast metastases from gastric cancer are extremely rare. A case report of a 37-year-old female with breast inflammatory invasion and ascites is described. Breast biopsy revealed carcinomatous invasion of the lymphatics from adenocarcinoma cells with signet-ring features.Estrogen (ER) and progesterone receptors (PR) and c-erb-B2 were negative. Upper gastrointestinal endoscopy revealed a prepyloric ulcerative mass. Histopathologic examination of the lesion showed infiltration from a highgrade adenocarcinoma, identical with that of the breast.Immunostaining was positive for cytokeratins CK-7 and CK-20 and CEA and negative for ER and PR. Ascitic fluid cytology was positive for adenocarcinoma cells. Mammography was not diagnostic. Abdominal CT scanning revealed large ovarian masses suggestive of metastases (Krukenberg's tumor). A cisplatin-based regimen was given but no objective response was observed. The patient died six months after initial diagnosis. A review of the literature is performed.

    Gastric signet ring cell carcinoma (GSRC) is a distinct entity. Their incidence is increasing. The pathologist plays a central role in the identification of this entity. Diagnosis is based on an adenocarcinoma containing a majority of signet ring cells (above 50 %). The prognosis of GSRC is the same as gastric adenocarcinoma while GSRC appeared more aggressive. Signet ring cells present a low sensitivity to chemotherapy. This review aimed to discuss the histological, the prognostic and the therapeutic aspect of this entity. PMID:24440764

  4. Radiologic diagnosis and staging of pancreatic ductal adenocarcinoma

    Balci, N. Cem E-mail: ncbalci@hotmail.com; Semelka, Richard C

    2001-05-01

    This article presents imaging modalities in the diagnosis and staging of pancreatic ductal adenocarcinoma. Magnetic resonance imaging (MRI) and endoscopic ultrasonography (EUS) have the highest accuracy in detection of pancreatic cancer. MRI and EUS have similar accuracy in determining the local extent of pancreatic cancer. Angiography, computed tomography (CT) angiography and EUS are similarly accurate in evaluating peripancreatic vascular involvement. MRI is the superior method for detecting liver metastases and peritoneal implants of pancreatic ductal adenocarcinoma. Endoscopic retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography (MRCP) are used to assess the biliary tract of patients with pancreatic cancer. Positron emission tomography (PET) is useful in distinguishing pancreatic cancer from focal pancreatic inflammation.

    2016-01-01

    This report describes two cases with obstructive jaundice caused by poorly differentiated gastric adenocarcinoma. Computed tomography scans showed circumferential stenosis in the hilar bile ducts. Endoscopic retrograde cholangiopancreatography showed dilatation of the bilateral hepatic ducts and stenosis of the common hepatic ducts from the bifurcation of the bilateral hepatic ducts. The first diagnoses were hilar cholangiocarcinoma and biliary drainage decreased serum bilirubin; however, both patients died of cancer within a short period of time. Autopsies revealed lymphatic vessel invasion and possible subepithelial invasion by gastric adenocarcinoma into the hilar bile ducts. A differential diagnosis should thus be required in suspected cases of hilar cholangiocarcinoma. PMID:27301505

  17. Correlation of Histologic Subtypes and Molecular Alterations in Pulmonary Adenocarcinoma: Therapeutic and Prognostic Implications.

    Kim, Jiyoon; Jang, Se Jin; Choi, Chang Min; Ro, Jae Y

    2016-09-01

    Major driver mutations of pulmonary adenocarcinomas have been identified and highlighted as actionable targets for precision cancer medicine. As phenotype is largely determined by genotype, genetic changes associated with morphologic features have recently received more attention from both pathologists and clinicians. The morphologic features of adenocarcinomas with mutations in EGFR or KRAS, or translocated ALK, have rarely been described. Pulmonary adenocarcinomas with EGFR mutations, the most common driver mutation encountered in Asian patients with pulmonary adenocarcinoma, show lepidic or papillary organotypic growth patterns. KRAS-mutated adenocarcinomas demonstrate nonorganotypic growth patterns, especially mucin-containing cells. P53 mutations are associated with aggressiveness rather than growth patterns. HER2 mutations are observed in mucinous adenocarcinoma and adenocarcinoma with micropapillary features. The histologic features of BRAF-mutated adenocarcinomas have not yet been established, but papillary, lepidic, solid, and acinar patterns have been observed. Adenocarcinomas with rearrangement of ALK, ROS1, and RET genes share similar histologic features, such as solid signet-ring cells and cribriform formation. However, adenocarcinomas with NRG1 rearrangements frequently show mucinous morphology. The histologic features and related mutations of adenocarcinomas with expression of programmed cell death-1 and programmed cell death ligands-1 may be helpful in guiding immunotherapeutic treatment. This review describes histopathologic features of adenocarcinomas and their correlation with molecular alterations. PMID:27403614

  19. Urinary Bladder Adenocarcinoma Metastatic to the Abdominal Wall: Report of a Case with Cytohistologic Correlation

    Vikas Nath

    2016-01-01

    Full Text Available We report a case of adenocarcinoma metastatic to the abdominal wall in a 71-year-old man with a history of primary bladder adenocarcinoma. CT-guided core biopsy was performed; imprints and histologic sections showed malignant glands lined by tumor cells with hyperchromatic nuclei and prominent nucleoli, infiltrating through skeletal muscle. Immunohistochemistry revealed positivity for CK7, membranous/cytoplasmic β-catenin, caudal-type homeobox transcription factor 2 (CDX2, and α-methylacyl coenzyme A racemase and negativity for CK20, p63, prostate-specific antigen (PSA, and prostate-specific acid phosphatase (PSAP. These findings were interpreted as metastatic adenocarcinoma, consistent with bladder primary. Primary bladder adenocarcinoma is a rare malignancy arising within glandular metaplasia and is associated with cystitis cystica and cystitis glandularis. Predisposing factors include bladder exstrophy, schistosomiasis, and other causes of chronic bladder irritation. This tumor is divided into intestinal, clear cell, and signet ring cell subtypes. Treatment involves radical cystectomy with pelvic lymph node dissection, and prognosis is unfavorable. Primary bladder adenocarcinoma should be differentiated from urachal adenocarcinoma, which arises from urachal remnants near the bladder dome, and secondary adenocarcinoma, or vesical involvement by adenocarcinoma from a different primary. CK7, CK20, CDX2, thrombomodulin, and β-catenin can help distinguish primary bladder adenocarcinoma from colonic adenocarcinoma; PSA and PSAP can help distinguish primary bladder adenocarcinoma from prostate adenocarcinoma.

    2013-01-01

    Full Text Available Simultaneous occurrence of prostatic adenocarcinoma and renal cell carcinoma is well documented in the literature. However, metastatic prostatic adenocarcinoma in a kidney harboring a renal cell carcinoma (RCC is quite rare. Although renal cell carcinoma is the most common tumor that can harbor metastasis, metastatic prostatic adenocarcinoma in a kidney harboring a RCC is quite rare. There are four cases in the literature showing metastasis of prostatic adenocarcinoma to RCC. However, as per our knowledge, this is the first case of a collision between RCC and metastatic prostatic adenocarcinoma.

  9. A case report of metastatic adenocarcinoma of the gingiva

    Buddula Aravind

    2009-01-01

    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.

  10. Synchronous collision neuroendocrine tumor and rectal adenocarcinoma: a case report.

    Zhu, Jie-Gao; Zhang, Zhong-Tao; Wu, Guo-Cong; Han, Wei; Wang, Kang-Li

    2015-04-01

    Collision tumors are thought to arise from the accidental meeting of two independent tumors. Adenocarcinoma is the most common malignant rectal tumor, while neuroendocrine tumor (NET) is relatively rare. Due to the endoscopy and reporting, the overall incidence of NETs was increasing recently but still less than 1 per 100,000. This means that a combination of an adenocarcinoma and NET is a very rare finding and an actual collision of these tumors even more so. We report here a highly unusual case of a 64-year-old woman who had collision tumors composed of a primary rectal adenocarcinoma and NET showing a "side by side" pattern. Resection margins are free of both the tumors. The postoperative course was uneventful. The patient underwent a protocol CT scan at 3 months after surgery, which did not show any recurrence. Both the malignant adenocarcinoma and the NET would make a great influence in the rest lifetime and a follow up will be continued, although the CT did not show any recurrence until now. To the best of our knowledge, this is the first reported case of such an occurrence. PMID:25972691

  12. The postoperative complication for adenocarcinoma of esophagogastric junction

    Hui Zhang

    2015-01-01

    Full Text Available Objective: The purpose of this study was to evaluate the postoperative complications for patients with adenocarcinoma of esophagogastric junction. Methods: Two hundred and eighty subjects with adenocarcinoma of esophagogastric junction who received operation were retrospectively analyzed from June 2006 to December 2010 in the Department of Oncology of First Affiliated Hospital of Bengbu Medical College, Bengbu, China. The postoperative complication such as ventricular premature beat, atrial fibrillation, supraventricular tachycardia, heart failure, pulmonary infection, pulmonary atelectasis, respiratory failure, bronchospasm, anastomotic leakage, gastroplegia, pleural infection, and cerebral accident were reviewed and recorded by to doctors. Moreover, the correlation between clinical characteristics and postoperative complication was analyzed by statistical methods. Results: A total of 70 complications were found for the included 280 cases of adenocarcinoma of esophagogastric junction with general incidence of 25%. For the relationship between clinical characteristics and postoperative complication analysis, no significant association of gender, age, operation time, operative approach, tumor differentiation, and clinical states was found with the postoperative complications (P > 0.05; but the complication rate in patients with basic disease of heart and lung was significant than the patients without this kind of disease (P < 0.05. Conclusion: The positive operative complications for patients with adenocarcinoma of esophagogastric junction were relative high. Moreover, basic heart and lung diseases can increase the risk of developing positive operative complications.

  16. Advanced Gastric Neuroendocrine Carcinoma with an Adenocarcinoma Component

    Masashi Miguchi

    2012-01-01

    Full Text Available In the present study, we observed that the adenocarcinoma component in the mucosa was continuous with neuroendocrine carcinoma (NEC in the deeper layers; this suggests the normal course of NEC carcinogenesis at the histological level. A 72-year-old man was admitted to our hospital with a chief complaint of tarry stools. Endoscopic examination of the upper gastrointestinal tract revealed a 2-cm tumor, with a deep central depression, surrounded by a smooth elevated area, in the middle of the stomach body. A biopsy showed that the tumor was a moderately differentiated gastric adenocarcinoma. The patient underwent total gastrectomy and standard lymph node dissection. The resected tumor was a 3.5 × 2.5 cm type 2 lesion. It comprised two elements at the histological level: (i a moderately differentiated adenocarcinoma in the superficial portion of the mucous membrane layer, and (ii NEC-like cells with dark, round nuclei and scant cytoplasm, presenting a solid and trabecular pattern, in the submucosal and muscularis propria layers. Immunohistochemical findings showed that the NEC-like cells were diffusely positive for chromogranin A, synaptophysin, neural cell adhesion molecule, and neuron-specific enolase, but were negative for carcinoembryonic antigen. The Ki-67 labeling index was 95%. The final pathological diagnosis was gastric NEC with an adenocarcinoma component and a high cellular proliferative potential.

  17. Radiographic and pathological analysis of small lung adenocarcinoma using the new IASLC classification

    Aim: To analyse the correlation between computed tomography (CT) findings of small lung adenocarcinomas and the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society Classification of Lung Adenocarcinoma. Materials and methods: A retrospective review of 300 lung adenocarcinoma lesions (size ≤20 mm) after surgical resection in 295 consecutive patients was performed. Tumours were defined as air-containing type if the ratio of the maximum dimension of the tumour on mediastinal windows to the maximum dimension of the tumour on lung windows was ≤50%, and as solid-density type if the ratio was >50%. The incidence between CT findings (air bronchogram, vascular involvement, pleural tags, notches, and spiculation) and pathological findings were investigated. Results: Of the 142 air-containing lesions, 114 were adenocarcinoma in situ (AIS), 28 were minimally invasive adenocarcinoma (MIA), and none of the lesions were invasive adenocarcinoma. Of the 158 solid-density lesions, 30 were AIS, 24 were MIA, and 104 were invasive adenocarcinoma. Notches and pleural tags were commonly observed in cases of invasive adenocarcinoma (p < 0.05). Conclusions: In the air-containing type of small lung adenocarcinomas, AIS and MIA were observed but no cases of invasive adenocarcinoma were found. The presence of notches and pleural tags were a significant factor in invasive adenocarcinoma.

    There have been sporadic reports about synchronous as well as metachronous gastric adenocarcinoma and primary gastric lymphoma. Many reports have dealt with metachronous gastric adenocarcinoma in mucosa-associated lymphoid tissue lymphoma of stomach. But to our knowledge, there have been no reports that document the increased incidence of metachronous gastric adenocarcinoma in patients with gastric diffuse large B-cell lymphoma. This retrospective study was conducted to estimate the incidence of metachronous gastric adenocarcinoma after primary gastric lymphoma treatment, especially in diffuse large B-cell lymphoma. The retrospective cohort study of 139 primary gastric lymphoma patients treated with radiotherapy at our hospital. Mean observation period was 61.5 months (range: 3.7-124.6 months). Patients profile, characteristics of primary gastric lymphoma and metachronous gastric adenocarcinoma were retrieved from medical records. The risk of metachronous gastric adenocarcinoma was compared with the risk of gastric adenocarcinoma in Japanese population. There were 10 (7.2%) metachronous gastric adenocarcinoma patients after treatment of primary gastric lymphomas. It was quite high risk compared with the risk of gastric carcinoma in Japanese population of 54.7/100,000. Seven patients of 10 were diffuse large B-cell lymphoma and other 3 patients were mixed type of diffuse large B-cell lymphoma and mucosa associated lymphoid tissue lymphoma. Four patients of 10 metachronous gastric adenocarcinomas were signet-ring cell carcinoma and two patients died of gastric adenocarcinoma. Metachronous gastric adenocarcinoma may have a more malignant potential than sporadic gastric adenocarcinoma. Old age, Helicobacter pylori infection and gastric mucosal change of chronic gastritis and intestinal metaplasia were possible risk factors for metachronous gastric adenocarcinoma. There was an increased risk of gastric adenocarcinoma after treatment of primary gastric lymphoma

Methods: The clinicopathological and immunohistochemical data of seven patients with ductal adenocarcinoma of the prostate were retrospectively analyzed. All patients underwent physical examination, magnetic resonance imaging (MRI, bone scan, cystoscopy, and computed tomography (CT scan. The level of prostate-specific antigen (PSA before and after surgery was assessed. Different prostate cancer markers were used for immunohistochemical staining. Results: The mean age of the seven patients diagnosed with prostatic ductal adenocarcinoma in this study was 76.2 years (range 57–88. Five patients presented with intermittent and painless gross hematuria, one patient with progressive dysuria, and one patient with elevated serum PSA on routine health examination. The level of PSA before surgery ranged from 1.3 to 45.0 ng/mL. Immunohistochemical staining results of the prostatic ductal adenocarcinoma confirmed positivity for PSA, prostatic acid phosphatase, androgen receptor, and alpha-methyacyl co-enzyme A (CoA-reductase markers. Two of the patients underwent bilateral orchiectomy combined with anti-androgen therapy, three underwent transurethral resection of prostate, one received radical prostatectomy, and one received medical castration therapy. The clinical outcomes of all patients were satisfactory, based on follow-up data. The symptoms of hematuria and dysuria were ameliorated well, and the postoperative PSA level decreased below 4.0 ng/mL. Recurrence or metastasis of disease was

    Full Text Available Primary mucinous adenocarcinoma is an extremely rare type of bladder cancer, with aggressive behavior and poor response to chemotherapy and radiotherapy. The symptoms are similar to those of other bladder tumors. Surgery is the main treatment and remains the only curative option. There may be a progression from mucinous metaplasia to mucinous adenoma and then mucinous adenocarcinoma. We present the case of a 40-year-old woman with recurrent lower urinary tract infections, submitted to imaging tests, which showed a bladder tumor. After transurethral resection, pathology showed intestinal mucinous carcinoma. Metastatic work-up was negative. New surgical procedure showed metaplasia but no recurrence of the carcinoma. The patient is now using antibiotic prophylaxis and will undergo a cystoscopy every 3 months and computed tomography in one year.

  1. Complete invagination of vermiform appendix with adenocarcinoma: case report

    Appendiceal intussusception is a very rare pathological condition, an incidence, as revealed by appendectomy specimens, of only 0.01 percent. There are various types among which complete invagination of the appendix is very rare. We encountered a case of intussusception of the appendix with complete invagination induced by appendiceal adenocarcinoma. A preoperative diagnosis of appendiceal adenocarcinoma and intussusception was not possible, but a final pathological report confirmed these conditions and retrospective analysis of a barium enema showed a finger-like filling defect of the cecum, a relatively specific finding in such cases. We describe a case involving a 39-year old man who one month earlier had noted the onset of pain in the right lower abdomen. (author)

    2013-01-01

    To evaluate if heterogeneity of tissue cancer antigen 125 (CA125) expression is present in epithelial serous adenocarcinomas. Furthermore, to investigate whether there is a correlation between levels of CA125 tissue expression, serum level of CA125, stage, and grade. A total of 10 patients...... diagnosed with serous ovarian adenocarcinomas were included. Preoperative blood samples were collected to determine serum CA125 levels. Tumor tissue from primary surgery was collected and processed for immunohistochemical analyses. CA125 was expressed in varying degrees in tumor tissues from all patients....... Mean tissue CA125 expression for each patient ranged from 36% to 98%. Intrapatient variations in tissue expression ranged from 10% to 90% point. No significant correlations between levels of CA125 tissue expression, serum level of CA125, stage, and grade were found. We found that the tissue expression...

  3. Gallbladder adenocarcinoma and paraneoplastic parathyroid hormone mediated hypercalcemia.

    Yogarajah, Meera; Sivasambu, Bhradeev; Shiferaw-Deribe, Zewge

    2016-04-10

    Parathyroid hormone mediated hypercalcemia is not always exclusively primary hyperparathyroidism and rarely could be due to ectopic parathyroid hormone secretion from tumor cells. We present a case of 86-year-old female with metastatic gall bladder adenocarcinoma diagnosed eight months back who presented with generalized fatigue and poor oral intake and was found to be hypercalcemic with elevated parathyroid hormone levels. Imaging with technetium 99 m sestamibi scintigraphy with dual phase, subtraction thyroid scan (dual isotope scintigraphy), magnetic resonance imaging and ultrasonography did not demonstrate any parathyroid lesion in normal or ectopic sites. We believe that the tumor cells were the source of ectopic parathyroid hormone secretion as we had excluded all the other possibilities with extensive combined imaging thereby increasing the sensitivity of our testing. We report the first case of metastatic gall bladder adenocarcinoma with paraneoplastic ectopic parathyroid hormone secretion. PMID:27081650

    2016-04-01

    Urachal Carcinoma (UC) is a rare malignancy of urinary bladder. It is usually found in adults in advanced stages because the tumour often grows outside the bladder without producing clinical symptoms. Most of the cases are mucinous, intestinal or signet ring cell adenocarcinoma and the diagnosis is usually made on biopsy. Radiographic images of this tumour may show characteristic features with a midline solid or cystic mass in the anterior wall of bladder associated with small calcification, which is considered as a pathognomonic sign for the diagnosis of UC. We report a case of UC in an adult, whose radiographic images suggested an urachal tumour and Fine Needle Aspiration (FNA) cytology revealed an adenocarcinoma. Laparoscopic partial cystectomy with umbilectomy and pelvic node dissection was done without further histopathological confirmation. Surgical intervention of UC on the basis of FNA diagnosis has not been reported in the literature. PMID:27190817

    2013-03-01

    Full Text Available The mainstay treatment of ampullary and periampullary adenocarcinoma is pancreaticoduodenectomy. Unfortunately, there are no standard options available in the postoperative management due to the rarity of the malignancy and the absence of prospective trials. In this year ASCO Gastrointestinal Cancers Symposium three remarkable abstracts regarding the management of recurrent or metastatic ampullary and periampullary carcinoma were presented. The first study (Abstract #257 demonstrates that palliative reoperation should not be an option, because of its severe morbidity and high mortality. The second study (Abstract #317 supports that reirradiation is well tolerated and it could be used for palliative reasons and local control. The last study (Abstract #197 reveals the prognostic value of 92-gene RT-PCR assay and the authors support the use of this method for the management of metastatic periampullary adenocarcinoma when the primary pathological sample cannot be helpful.

  6. Metastatic ductal adenocarcinoma in a Western Hognose snake (Heterodon nasicus).

    Stern, Adam W; Velguth, Karen E; D'Agostino, Jennifer

    2010-06-01

    A 17-yr-old Western Hognose snake (Heterodon nasicus) presented with a prominent midcoelomic swelling. Surgical exploration revealed a large, multicystic, irregular, tan, and firm mass grossly effacing the splenopancreas. The mass was subsequently removed. Histologically, the mass was composed of tubules of columnar to flattened neoplastic cells with an abundant stroma and moderate cellular atypia consistent with a scirrhous adenocarcinoma, likely ductal in origin, given the location of the neoplastic mass. Bloodwork revealed anemia, monocytosis, marked hypercalcemia, and, postoperatively, persistent hyperglycemia. After postoperative recovery, the snake was diagnosed with iatrogenically induced diabetes mellitus and exocrine pancreatic insufficiency. Due to the inability to clinically control the diabetes mellitus and exocrine pancreatic insufficiency and when additional palpable masses were noted, the snake was euthanatized. Necropsy and histopathologic examination confirmed metastasis of the previously removed adenocarcinoma to the liver, right kidney, and large intestine. PMID:20597225

  7. Imaging of pancreatic adenocarcinoma with emphasis on multidetector CT

    Pancreatic adenocarcinoma is the fourth most frequent cause of cancer-related death. The incidence is increasing and the overall survival has altered little in recent years. Moreover, patients usually present late with inoperable disease and curative resection by standard pancreatico-duodenectomy (Whipple's procedure) is associated with significant morbidity. It should only be attempted in that small group of patients lacking radiological evidence of advanced disease. Despite the recent advances in body magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS), computed tomography (CT) is the mainstay of staging in most centres and the recent development of multidetector CT machines (MDCT) has raised hope of an improvement in preoperative staging. This review focuses on the CT of pancreatic adenocarcinoma with particular emphasis on examination technique and on those criteria that determine resectability

    A 29-year-old woman had undergone gastrocystoplasty with Mitrofanoff appendicovesicostomy for urethral trauma at 9 years of age. Since then, she was being followed up for performing clean intermittent self-catheterization at regular intervals. Twenty years after the surgery, she presented with gross hematuria. Ultrasonographic findings revealed bilateral hydronephrosis. Cystoscopy and computed tomography (CT) revealed invasive bladder cancer with pelvic lymph node metastases. A biopsy confirmed the diagnosis of adenocarcinoma with signet ring cell carcinoma. Subsequently, neo-adjuvant combination chemotherapy with TS-1 and cisplatin (CDDP) was initiated, which was followed by open radical cystectomy with extended pelvic lymphadenectomy. The tumor was found to infiltrate from the anastomotic site into the entire native bladder and histopathological diagnosis was muscle invasive adenocarcinoma with neuroendocrine differentiation and lymph node metastasis (ypT3bN2). TS-1 was continued as adjuvant chemotherapy and the patient did not have any evidence of recurrence for 12 months postoperatively. PMID:26932334

    2016-01-01

    Here, we report the case of a 77-year-old male patient who was revealed to have an unsuspected case of gastric adenocarcinoma with paravertebral plasmacytoma following biopsy. Plasmacytoma may be classified into two main groups: Multiple myeloma and plasmacytoma without marrow involvement. It comprises isolated plasmacytoma of the bone and extramedullary plasmacytoma. Extramedullary plasmacytoma (EMP) accounts for 3% of all plasmacytomas; however, ~80% are located in the upper respiratory tract and upper gastrointestinal tract. It occurs extremely rarely in paravertebral areas. Case reports of EMP and other types of malignant tumor occurring at the same time have not been identified in searches of the literature. In the present study, we describe the diagnosis and treatment process of a case of gastric adenocarcinoma concurrent with paravertebral plasmacytoma. It may be helpful for early clinical diagnosis and treatment of such cases.

    Hyperamylasemia in patients with lung cancer is rarely, comprising 1% to 3% of all lung cancers. This report describes two cases of lung adenocarcinoma coexisting with hyperamylasemia in two women aged 77 and 57, respectively. In these two cases, CT revealed a normal pancreas. We monitored the serum and urine amylase levels during therapy and found it paralleled tumor response to chemotherapy and metastasis. We suggest that the amylase levels are related to the tumor size and might be a valua...

    Base excision repair and nucleotide excision repair are vital responses to multiple types of DNA damage, including damage from tobacco exposure. Single-nucleotide polymorphisms (SNP) in these pathways may affect DNA repair capacity and therefore influence risk for cancer development. We performed a clinic-based, case-control study comprising 481 consecutive patients with confirmed pancreatic adenocarcinoma and 625 healthy controls. Allele and genotype frequencies for 16 SNPs in DNA repair gen...

    2016-01-01

    Treatment options for advanced pancreatic ductal adenocarcinoma (PDAC) are limited; however, new therapies targeting specific tumor-related molecular characteristics may help certain patient cohorts. Emerging preclinical data have shown that inhibition of mammalian target of rapamycin (mTOR) in specific KRAS-dependent PDAC subtypes leads to inhibition of tumorigenesis in vitro and in vivo. Early phase II studies of mono-mTOR inhibition have not shown promise. However, studies have shown that ...

    Small cell carcinoma (SCC) or microcytic carcinoma of the urinary bladder is a rare entity comprising approximately 0.5% of all bladder tumors. Due to its rarity, no prospective studies evaluating the most effective treatment have been published in the medical literature. Several cases of bladder SCC have been presented so far. We describe our case report and we revise the recent literature. Our patient was diagnosed with pure bladder SCC and prostatic adenocarcinoma. After the initial and co...

    Tumwine Lynnette K

    2012-02-01

    Full Text Available Abstract Introduction Adenocarcinoma of the colon is the most common histopathological type of colorectal cancer. In Western Europe and the United States, it is the third most common type and accounts for 98% of cancers of the large intestine. In Uganda, as elsewhere in Africa, the majority of patients are elderly (at least 60 years old. However, more recently, it has been observed that younger patients (less than 40 years of age are presenting with the disease. There is also an increase in its incidence and most patients present late, possibly because of the lack of a comprehensive national screening and preventive health-care program. We describe the clinicopathological features of colorectal carcinoma in the case of a young man in Kampala, Uganda. Case presentation A 27-year-old man from Kampala, Uganda, presented with gross abdominal distension, progressive loss of weight, and fever. He was initially screened for tuberculosis, hepatitis, and lymphoma, and human immunodeficiency virus/acquired immunodeficiency syndrome infection. After a battery of tests, a diagnosis of colorectal carcinoma was finally established with hematoxylin and eosin staining of a cell block made from the sediment of a liter of cytospun ascitic fluid, which showed atypical glands floating in abundant extracellular mucin, suggestive of adenocarcinoma. Ancillary tests with alcian blue/periodic acid Schiff and mucicarmine staining revealed that it was a mucinous adenocarcinoma. Immunohistochemistry showed strong positivity with CDX2, confirming that the origin of the tumor was the colon. Conclusions Colorectal carcinoma has been noted to occur with increasing frequency in young adults in Africa. Most patients have mucinous adenocarcinoma, present late, and have rapid disease progression and poor outcome. Therefore, colorectal malignancy should no longer be excluded from consideration only on the basis of a patient's age. A high index of suspicion is important in the

    2013-01-01

    Background The prevalence of vitamin D deficiency among patients with cancer has been previously reported. Because vitamin D is fat soluble, patients with pancreatic adenocarcinoma may have an especially high risk of vitamin D deficiency in association with ongoing and varying degrees of malabsorption. However, little is known about the correlation between vitamin D status and prognosis in these patients. Methods We conducted a retrospective review of vitamin D status in patients with pancrea...

  10. Treatment of squamous cell and adenocarcinoma of the esophagus

    Rathbone B

    2012-11-01

    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

  11. Ultrasonographic features of intestinal adenocarcinoma in five cats

    Adenocarcinoma, followed by lymphosarcoma, are the most common feline intestinal neoplasms. Clinicopathological, survey radiographic, and ultrasonographic findings of five cats with intestinal adenocarcinoma are reported. An abdominal mass was palpable in all five cats, but the mass could be localized to bowel in only two cats. Radiographically an abdominal mass was detected in only one cat. Ultrasonographically there was a segmental intestinal mural mass in all five cats. The mass was characterized by circumferential bowel wall thickening with transmural loss of normal sonographic wall layers. In one cat, the circumferential symmetric hypoechoic bowel wall thickening was similar to that reported for segmental lymphoma. In the other four cats, the sonographic features of the thickened bowel wall were varied, being mixed echogenicity and asymmetric in 3 cats and mixed echogenicity and symmetric in one. The results of the present report suggest that sonographic observation of mixed echogenicity segmental intestinal wall thickening in the cat represents adenocarcinoma rather than lymphosarcoma, although other infiltrative diseases should be considered

    Full Text Available The purpose of this case report is to point out the diagnostic value of cytologic smears in patients presenting with anorectal complaints, such as bleeding, pain or discomfort, which may suggest a neoplastic lesion. We present a case of a 64-year-old man with a 3 months′ history of anal bleeding and pain during defecation. He was diagnosed as having hemorrhoids and a hemorrhoidectomy was performed. The patient developed an anal stricture postoperatively that required operative dilation. He continued to complain about anorectal pain for 2 months and a subsequent rectoscopy revealed the presence of tumor 5 to 7 cm above the dentate line. The tumor was resected laparoscopically and was reported as an adenocarcinoma. Rectal bleeding recurred 18 months postoperatively and a smear was procured from the anorectal mucosal surface for cytologic evaluation. A definitive diagnosis of adenocarcinoma was rendered based on cytologic and histologic examination of the material. To the best of our knowledge, this is the first case report of anorectal adenocarcinoma diagnosed by cytologic smear in the English literature.

    Objectives: To describe perfusion CT features of locally advanced pancreatic ductal adenocarcinoma and to evaluate correlation with tumor grading. Methods: Thirty-two patients with locally advanced pancreatic adenocarcinoma were included in this study. Lesions were evaluated by P-CT and biopsy after patient's informed consent. P-CT parameters have been assessed on a large single and on 6 small intratumoral ROIs. Values obtained have been compared and related to the tumor grading using Mann–Whitney U test. Sensibility, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy in predicting tumor grading have been calculated for cut-off values chosen by using ROC curves. Results: Out of 32 lesions, 12 were classified as low grade and 20 as high grade. A statistically significant difference between high and low grade neoplasms were demonstrated for PEI and BV parameters. PEI and BV cut-off values were respectively 17.8 HU and 14.8 ml/100 g. PEI identified high grade neoplasms with a 65% sensitivity, 92% specificity, 93% PPV, 61% NPV and 75% accuracy. BV identified high grade neoplasms with a 80% sensitivity, 75% specificity, 84% PPV, 69% NPV, 78% accuracy. Considering both PEI and BV, P-CT identified high grade lesions with a 60% sensitivity, 100% specificity, 100% PPV, 60% NPV and 75% accuracy. Conclusions: PEI and BV perfusion CT parameters proved their efficiency in identifying high grade pancreatic adenocarcinoma.

    Full Text Available Context: According to the recent World Health Organization reports, lung cancer has become the most common type of malignancy and the leading cause of death from cancer. Lung cancer frequently metastasizes to hilar lymphnodes, brain, adrenal glands, bone, but rarely to skin. Case Report: We report a case of a 72-year-old male with a past medical history of pulmonary fibrosis and no prior history of smoking who presented to the emergency room for progressive dyspnea over three weeks. The patient reported having a rapidly growing scalp lesion as well. A computed tomography (CT scan of the chest showed diffuse fibrotic changes and multiple densities of different diameters; a CT guided biopsy of lung revealed a poorly differentiated adenocarcinoma. Excision of right scalp lesion was performed, and pathology revealed poorly differentiated malignant neoplasm favoring adenocarcinoma. Conclusion: We are presenting a rare case of lung adenocarcinoma presenting with skin metastasis, which was simultaneously diagnosed during the same hospitalization. Although cutaneous metastasis from the lung is rare, it must be ruled out in patients with suspicious skin lesions, smoking history, or lung cancer.

  15. Ductal adenocarcinoma of the prostate: histogenesis, biology and clinicopathological features.

    Seipel, Amanda H; Delahunt, Brett; Samaratunga, Hemamali; Egevad, Lars

    2016-08-01

    Ductal adenocarcinoma of the prostate (DAC) is recognised as a subtype of prostatic adenocarcinoma, but its diagnostic criteria and biology remain controversial. DAC was first thought to stem from Müllerian duct remnants, but further studies suggest a prostatic origin. DAC is composed of tall, columnar, pseudostratified epithelium with a papillary, cribriform, glandular or solid architecture. The diagnosis is based on morphology alone with papillary architecture being the most helpful diagnostic feature. The tumour is rare in a pure form and most cases are combined with acinar adenocarcinoma. The most common differential diagnoses of DAC are intraductal carcinoma of the prostate and high-grade prostatic intraepithelial neoplasia. Patients often present at an advanced clinicopathological stage. High rates of extra-prostatic extension, seminal vesicle invasion, local and regional metastases, and positive surgical margins are seen after radical prostatectomy. DAC metastasises to sites that are less commonly seen for prostate cancer such as lung, brain, testis and penis. The morphology and the unusual metastatic locations make the accurate diagnosis of metastases challenging, but a positive immunostain for prostate specific markers may be helpful. The correct identification of DAC has implications for treatment as well as outcome. PMID:27321992

    Tohda, Gen; Osawa, Takeshi; Asada, Yasuyuki; Dochin, Masaki; Terahata, Shintarou

    2016-02-25

    Gastric adenocarcinoma of fundic gland type (GA-FG) with chief cell differentiation was recently proposed as an extremely rare type of gastric adenocarcinoma. Here, we report 4 cases of GA-FG with chief cell differentiation. Endoscopic features included a submucosal tumor shape or a flat shape, whitish discoloration and dilated vessels on the surface. The tumors were located in the upper or middle third of the stomach. All cases were preoperatively diagnosed as GA-FG by biopsy, and endoscopic submucosal dissection was performed. Resected specimens revealed well-differentiated adenocarcinomas resembling chief cells. Tumor cells were diffusely positive for pepsinogen-I, but partially positive for H(+)/K(+)-ATPase in scattered locations around the tumor margin. Despite the presence of minimal invasion of the carcinoma into the submucosal layer, which was observed in two cases, neither lymphatic nor venous invasion was detected in any of the cases. Finally, all cases showed less aggressive clinical behavior with low grade malignancy. PMID:26962407

    2004-09-01

    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.

    Despite the prevalence and significant morbidity resulting from estrogen receptor positive (ER(+)) breast adenocarcinomas, there are only a few models of this cancer subtype available for drug development and arguably none for studying etiology. Those models that do exist have questionable clinical relevance. Given our goal of developing luminal models, we focused on six cell lines derived by minimal mutagenesis from normal human breast cells, and asked if any could generate clinically relevant xenografts, which we then extensively characterized. Xenografts of one cell line, 184AA3, consistently formed ER(+) adenocarcinomas that had a high proliferative rate and other features consistent with "luminal B" intrinsic subtype. Squamous and spindle cell/mesenchymal differentiation was absent, in stark contrast to other cell lines that we examined or others have reported. We explored intratumoral heterogeneity produced by 184AA3 by immunophenotyping xenograft tumors and cultured cells, and characterized marker expression by immunofluorescence and flow cytometry. A CD44(High) subpopulation was discovered, yet their tumor forming ability was far less than CD44(Low) cells. Single cell cloning revealed the phenotypic plasticity of 184AA3, consistent with the intratumoral heterogeneity observed in xenografts. Characterization of ER expression in cultures revealed ER protein and signaling is intact, yet when estrogen was depleted in culture, and in vivo, it did not impact cell or tumor growth, analogous to therapeutically resistant ER(+) cancers. This model is appropriate for studies of the etiology of ovarian hormone independent adenocarcinomas, for identification of therapeutic targets, predictive testing, and drug development.

  19. Reversible postvaccination paraneoplastic encephalomyelitis in a patient with lung adenocarcinoma.

    Wu, Yi-Jen; Lai, Ming-Liang; Huang, Chin-Wei

    2010-12-01

    Encephalomyelitis occurs in paraneoplastic syndrome and acute disseminated encephalomyelitis through different autoimmune mechanisms. No postvaccinal encephalomyelitis other than acute disseminated encephalomyelitis has been reported in patients with malignancy. A 68-year-old woman was admitted because of a headache followed by a gait disturbance and psychomotor retardation 2 days after she had received an influenza vaccination followed by abulia, limb rigidity and hyperreflexia of both legs, and meningeal irritation. Cerebrospinal fluid studies showed increased intracranial pressure, elevated immunoglobulins G and A, and pleocytosis. Contrasted brain magnetic resonance imaging revealed ventriculomegaly and multiple symmetric leptomeningeal enhancement, without demyelinating changes or cortical ribbon signs. Somatosensory evoked potentials and nerve conduction velocity studies suggested myelitis. Encephalomyelitis was diagnosed on the basis of clinical and laboratory examinations. The etiological survey identified a lung adenocarcinoma. Both the encephalomyelitis and the lung adenocarcinoma simultaneously progressed after the vaccination and then, after targeted therapy for lung cancer, simultaneously subsided. In conclusion, postinfluenza-vaccination paraneoplastic encephalomyelitis may occur in patients with lung adenocarcinoma. PMID:20964557

  20. Prostate-Type Adenocarcinoma in Mature Cystic Ovarian Teratoma.

    Stanhiser, Jamie; Mahdi, Haider; Rosa, Gabriela; Harper, Holly; Shepard, Dale; Rose, Peter G; Roma, Andres A

    2016-03-01

    We report our experience with prostatic-type tissue in ovarian teratomas, and in particular we highlight a case of prostatic-type adenocarcinoma arising within a mature cystic ovarian teratoma in a 32-yr-old woman. On gross examination, the cyst consisted of typical features of a dermoid cyst. Closer examination revealed a single 1.5-cm solid nodule within the cyst. Microscopically, it was composed of a small cyst-like structure lined by urothelium and to one side glandular and stromal tissue consistent with prostate parenchyma. Within the prostatic-type tissue, there were malignant glands morphologically and immunohistochemically supportive of prostatic-type adenocarcinoma Gleason score 3+3=6. There were also areas consistent with high-grade prostatic intraepithelial neoplasia. Although there are several reports in the literature of benign prostatic-type tissue arising within ovarian as well as testicular teratomas, to our knowledge, prostatic-type adenocarcinoma arising in a mature ovarian teratoma is an extremely rare phenomenon, with only 1 previous report in the literature. PMID:26352547

  1. Magnetic resonance imaging findings of endometrioid adenocarcinoma of the ovary

    We assessed magnetic resonance imaging (MRI) features and clinical characteristics of ovarian endometrioid adenocarcinoma. A total of 31 patients with 39 surgically proven ovarian endometrioid adenocarcinomas were analyzed retrospectively. Histologically, 13 lesions in 12 patients arose from proven endometriomas (group A), and 26 lesions in 19 patients did not coexist with endometrioma (group B). The morphological pattern of the lesion on MRI was classified as a solid or a cystic type: A solid type was defined as a solid component occupying more than half of the lesion; and a cystic type was a cystic lesion with one or more mural nodules. Altogether, 11 lesions in group A were the cystic type on MRI, whereas 24 lesions in group B were the solid type (P<0.0001). Among the 11 cystic-type lesions in group A, the cysts of 5 lesions were hypointense on T1-weighted images, and the cysts of 6 lesions were hyperintense on T1- and T2-weighted images without shading.'' The nuclear grade was higher (P=0.0028) and the clinical stage more advanced (P=0.0018) in group B compared to group A. MRI of ovarian endometrioid adenocarcinomas revealed two types: a solid type and a cystic type. The lesions arising from endometriomas tended to be the cystic type on MRI and have a good prognosis. Preexisting endometrioma in this entity rarely showed ''shading'' on T2-weighted images. (author)

  2. Clinical significance of clusterin expression in pancreatic adenocarcinoma

    Jin Junshuo

    2012-07-01

    Full Text Available Abstract Background Clusterin is known to be expressed in many human neoplasms, and is believed to participate in the regeneration, migration, and anti-apoptosis of tumor cells. However, few reports have addressed the relationship between the manifestation of clusterin and clinicopathologic parameters in pancreas cancer patients. In the present study, the authors investigated the expression of clusterin and its clinical significance in pancreatic adenocarcinoma. Methods Immunohistochemical staining was performed for clusterin in tumor tissues obtained from patients who received pancreatic resection with radical intent, and the associations of clusterin expression with various clinicopathologic parameters were analyzed in addition to the relation between its expression and survival. Results Immunoreactivity for clusterin was observed in 17 of the 52 (33% pancreatic adenocarcinomas examined. In addition, clusterin positivity was found to be associated with preoperative serum carcinoembryonic antigen level, perineural invasion, and, most strongly, lymph node metastasis. The survival analysis identified tumor differentiation and lymph node metastasis as the only significant prognostic factors. Conclusion Although not an independent prognostic factor, clusterin immunoreactivity can be used in conjunction with lymph node metastasis to predict survival in cases of pancreatic adenocarcinoma.

  3. A rare case of thyroid metastasis from pancreatic adenocarcinoma.

    Kelly, Michael E

    2012-02-01

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

  4. Imaging features of ovarian metastases from colonic adenocarcinoma in adolescents

    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.)

  5. Endorectal ultrasonography, strain elastography and MRI differentiation of rectal adenomas and adenocarcinomas

    Waage, Jo Erling Riise; Leh, Sabine; Røsler, Cornelia;

    2015-01-01

    AIM: Strain elastography is a method for recording tissue hardness. Strain in different areas may be compared using strain ratio (SR). The aims of this study were to validate a previously proposed SR cut-off value of 1.25 for differentiating adenocarcinomas from adenomas and to compare the...... adenomas from adenocarcinomas. ERUS and MRI were performed according to standard routine at the institution, defining T0 as adenomas and T1-4 as adenocarcinomas. Subsequent histopathology was used as reference standard. RESULTS: Histopathological evaluation revealed 21 adenomas and 99 adenocarcinomas...... confirms that the elastography SR assessment accurately differentiates sessile adenomas from adenocarcinomas. SR assessment has a superior ability to differentiate adenomas and adenocarcinomas when compared with ERUS and MRI. MRI examination seems unable to recognize adenomas, and should be interpreted...

  8. Value of napsin A and thyroid transcription factor-1 in the identification of primary lung adenocarcinoma

    Zhang, Peng; Han, Yi-Ping; Huang, Ling; Li, Qiang; Ma, Da-Lie

    2010-01-01

    Napsin A is a newly discovered functional aspartic proteinase that is expressed in normal lung parenchyma in type II pneumocytes and is thought to be associated with primary lung adenocarcinoma. Thyroid transcription factor-1 (TTF-1) is a widely used relatively restricted marker for lung adenocarcinoma. The present study aimed to compare the usefulness of napsin A with TTF-1 for the identification of primary lung adenocarcinoma. Immunohistochemical expression of napsin A and TTF-1 was analyze...

    Villoglandular adenocarcinoma (VGA) is a rare subtype of cervical adenocarcinoma with a more favorable prognosis compared to conventional adenocarcinomas. Although the tumors are usually recognized on colposcopic examination due to the mainly exophytic growth pattern, they may be underdiagnosed as benign lesions by cytology because of their minimal cytologic atypia. We report the liquid-based cytology (LBC) findings of three histologically confirmed VGAs which we have recently identified. The...

    2009-01-01

    Full Text Available Context : Clear cell adenocarcinoma of the urethra is an extremely rare tumour. Its histogenetic derivation remains controversial. Case report : We report a new case of clear cell adenocarcinoma of the proximal urethra in a 56-year-old woman who presented with grossly hematuria. Urethral cystoscopy revealed a tumour protruding from the posterior urethral wall at the bladder neck. Treatment consisted of urethrocystectomy with pelvic lymph node dissection. Histologically, the neoplasm consisted of clear cell adenocarcinoma of the urethra. Conclusion : It appears that female urethral adenocarcinoma has more than one tissue of origin.

  15. A case with primary signet ring cell adenocarcinoma of the prostate and review of the literature

    Orcun Celik

    2014-06-01

    Full Text Available Primary signet cell carcinoma of the prostate is a rare histological variant of prostate malignancies. It is commonly originated from the stomach, colon, pancreas, and less commonly in the bladder. Prognosis of the classical type is worse than the adenocarcinoma of the prostate. Primary signet cell adenocarcinoma is diagnosed by eliminating the adenocarcinomas of other organs such as gastrointestinal tract organs. In this case report, we present a case with primary signet cell adenocarcinoma of the prostate who received docetaxel chemotherapy because of short prostate specific antigen doubling time.

    Genetic abnormality in early-stage lung adenocarcinoma was examined to search for new prognostic biomarkers. Six in situ lung adenocarcinomas and nine small but invasive adenocarcinomas were examined by array-comparative genomic hybridization, and candidate genes of interest were screened. To examine gene abnormalities, 83 cases of various types of lung carcinoma were examined by quantitative real-time genomic PCR and immunohistochemistry. The results were then verified using another set of early-stage adenocarcinomas. Array-comparative genomic hybridization indicated frequent amplification at chromosome 3q26. Of the seven genes located in this region, we focused on the epithelial cell transforming sequence 2 (ECT2) oncogene, as ECT2 amplification was detected only in invasive adenocarcinoma, and not in in situ carcinoma. Quantitative PCR and immunohistochemistry analyses also detected overexpression of ECT2 in invasive adenocarcinoma, and this was correlated with both the Ki-67 labeling index and mitotic index. In addition, it was associated with disease-free survival and overall survival of patients with lung adenocarcinoma. These results were verified using another set of early-stage adenocarcinomas resected at another hospital. Abnormality of the ECT2 gene occurs at a relatively early stage of lung adenocarcinogenesis and would be applicable as a new biomarker for prognostication of patients with lung adenocarcinoma.

  17. Simultaneous large cell neuroendocrine carcinoma and adenocarcinoma of the stomach

    Tadashi Terada; Hirotoshi Maruo

    2011-01-01

    A large cell neuroendocrine carcinoma (LCNEC) of the stomach is very rare. A 76-year-old Japanese man was admitted to our hospital because of epigastralgia and nausea. Endoscopy revealed 2 large tumors in the stomach. He did not have multiple endocrine neoplasia type Ⅰ or Zollinger-Ellison syndrome. Imaging modali-ties, including computed tomography and magnetic resonance imaging, revealed no other tumors. Gas-trectomy, cholecystectomy, and lymph node dissection were performed. The resected stomach had 2 tumors: one was an antral ulcerated type 3 tumor measuring 5 cm x 5 cm, and the other was a polypoid type 1 tumor measuring 6 cm x 6 cm x 3 cm in the fundus. Micro-scopically, the antral ulcerated tumor was a well differ-entiated adenocarcinoma with deep invasion. The fun-dus polypoid tumor was a LCNEC, being composed of malignant large cells arranged in trabecular and nested patterns. The tumor cells were large and the nuclei were vesicular. Nucleoli were frequently present, and there were many mitotic figures, apoptotic bodies, and necrotic areas. Much lymphovascular permeation was seen. Seven out of 29 dissected lymph nodes showed metastatic foci; 6 were from the LCNEC and 1 from the adenocarcinoma. Many intravascular tumor emboli of LCNEC were seen in the peritoneum around the lymph nodes. Mucins were present in the adenocarcinoma but not in the LCNEC. Immunohistochemically, the LCNEC tumor cells were positive for pancytokeratins, synaptophysin (50% positive), chromogranin A (10% positive), Ki-67 (90% labeled), and platelet-derived growth factor-α (80% positive). They were negative for KIT, p53, CD56, and neuron-specific enolase. The non-cancerous stomach showed a normal number of endocrine cells. The patient is now treated with adju-vant chemotherapy.

  18. Role of surgical resection in treatment of pancreatic adenocarcinoma

    Milošević Pavle

    2011-01-01

    Full Text Available Introduction. Pancreatic adenocarcinoma is the fifth leading cause of death from malignant diseases. The total five-year rate is bellow 5%, but in patients who underwent pancreatic resection, the fiveyear rate may be up to 20%. Surgical resection is still the only therapeutic option that offers the possibility of cure. In recent decades, the perioperative mortality rate has been significantly reduced in the institutions performing a number of these operations per year and has become less than 5%. Postoperative morbidity remains high. Material and Methods. The results of surgical resection in the treatment of pancreatic adenocarcinoma have been analyzed. A retrospective study included the patients operated at the Department for Abdominal, Endocrine and Transplantation surgery, Clinical Center of Vojvodina. Results. In the period from February 1st 1998 to February 1st 2007 a total of 67 patients with pancreatic adenocarcinoma underwent resection. The average age of patients was 58.81±1.42 years. There were 44 (65.7% male and 23 (34.3% female patients. The most common locations of cancer were the head, then the body and the tail of the pancreas and they were found in 57 (85.1% cases, 7 (10,4% cases and 3 (4,47% cases, respectively. The postoperative mortality appeared in 3 (4.47% cases and postoperative morbidity in 21 (31.3% cases. The average survival was 22.89± 3.87 months, the median being 9.0±2.18 months. The five-year survival rate was 13.5%. Conclusion. For patients with pancreatic cancer, surgical resection still remains the only chance of cure. These procedures are performed with acceptable postoperative mortality and morbidity rate. The percentage of cured patients is still unsatisfactorily low.

    Robert Levin

    2016-08-01

    Full Text Available Context Seventy patients with adenocarcinoma of the pancreas with liver metastases, received chemotherapy every four weeks and their outcomes are reported in this retrospective series. Objective Advanced adenocarcinoma of the pancreas has a poor prognosis with only 2% 5-year survival reported by SEER (Surveillance, Epidemiology and End Results of the NCI. Chemotherapy given as intra-arterial perfusions is more intense than intravenous chemotherapy. Responses in perfused tumor is expected to be better than that obtained with only intravenous chemotherapy. Design Hepatic artery therapy is given monthly as a 5 hour perfusion of the hepatic artery using DDP and MIC. Also given is monthy Intravenous (IV therapy with four hours of Leucovorin (LV, with an injection of FUDR during the last hour of LV, daily x 5 days. Setting all therapy was given at Midwestern Regional Medical Center. Patients Thirty seven patients had no prior chemotherapy, while 33 patients had progressed after prior IV chemotherapy. Intervention Hepatic artery therapy with IV LV-FUDR was given for up to six months depending upon marrow tolerance and response. At that point, if response was ongoing or improving, therapy was continued monthly with only IV LV-FUDR; all therapy was stopped whenever progressive disease was evident. Results of those without prior chemotherapy, the mean overall survival (OS was 17.3 ± 30.2 months (mean±SD, ranging up to 13 years. Six patients survived more than three years with four are living in continuing complete remission for more than five years. Conclusion This therapy offers the opportunity for long term survival in a subset of patients with metastatic adenocarcinoma of the pancreas who have liver metastases, and some patients can be cured.

  20. Feasibility of carbon ion radiotherapy for locally advanced sinonasal adenocarcinoma

    Background and purpose: To evaluate the safety and efficacy of carbon ion radiotherapy (CIRT) for locally advanced sinonasal adenocarcinoma. Material and methods: Twenty-two patients with sinonasal adenocarcinoma were treated with CIRT. CIRT was the primary treatment for 16 patients. Four patients received CIRT for local recurrence after surgery and two for residual tumour after surgery or chemotherapy. At the start of CIRT, 1 patient had T-classification (T) 2 disease, 2 had T3 disease, 5 had T4a disease, and 14 had T4b disease. Fourteen patients were treated with 57.6 Gy equivalent (GyE)/16 fractions, and 8, with 64.0 GyE/16 fractions. Results: The median follow-up period was 43 months for all patients. The 3-year local control and loco-regional control rates for all patients were 76.9% (95% confidence interval [CI] = 56.7–97.1%) and 61.3% (95% CI = 38.5–84.1%), respectively. The 3-year overall survival and disease-specific survival rates were 59.1% (95% CI = 38.6–79.6%) and 65.6% (95% CI = 44.9–86.3%), respectively. Acute reactions of grade 3 of the skin and mucosa were observed in 2 and 4 patients, respectively. Late reactions included lateral visual loss (5 patients), mucosal ulceration (1 patient), and brain necrosis with clinical symptoms (1 patient). In the 5 patients who developed visual loss, the optic nerve was close to the tumour. Conclusions: CIRT was effective and generally safe for locally advanced sinonasal adenocarcinoma

    2012-01-01

    Bony metastases from ovarian cancer are rare, tend to affect the axial skeleton and are associated with abdomino-pelvic disease. The median time interval between diagnosis of ovarian carcinoma and presentation of bony metastases is 44 months (1). We describe a rare case of high grade left ovarian serous / endometrioid adenocarcinoma presenting with a pathological right femoral fracture 4 weeks following diagnosis and optimal debulking of the ovarian tumour. Orthopaedic surgeons must be vigilant when planning treatment of fractures presenting in patients with a history of ovarian cancer. PMID:24960734

  2. Pneumobilia Resulting From Choledochoduodenal Fistula Secondary to Metastatic Colon Adenocarcinoma

    Kramer, Scott; Tzimas, Demetrios; Saitta, Patrick

    2016-01-01

    Pneumobilia, or air within the biliary tree, is a poor prognostic indicator in a patient without prior biliary sphincterotomy. Differential diagnosis includes infection with gas-forming organisms, choledochoenteric fistula in the setting of gallstones or penetrating ulcer disease, malignant invasion from a primary liver or biliary tract tumor, or metastatic disease. Treatment depends on etiology and patient factors, but often requires surgical intervention. We report a patient with gastrointestinal bleeding in whom pneumobilia was incidentally noted on abdominal plain film. Computed tomography and endoscopy revealed the biliary-enteric fistula to be caused by metastatic colon adenocarcinoma invading the biliary tree. PMID:26958563

  3. Result of surgical therapy in esophagogastric junction adenocarcinoma

    To assess the outcome of surgical therapy and choice of surgical strategy for patients with adenocarcinoma of the gastroesophageal junction. Between February 1989 and January 2005 during 16 years, 335 patients (65 female, 270 male, mean age 56 years) with esophagogastric junction adenocarcinoma underwent surgical operation. The choice of surgical approach was based on the anatomical location of the tumor mass. Outcome of surgery, histopathologic characteristics, demographic data and long term survival rates were compared among three types of tumor defined as follows. Type I: Adenocarcinoma of the distal esophagus which infiltrates the esophagogastric junction from above. Type II: True carcinoma of the cardia arising immediately at the esophagogastric junction. Type III: Subcardial gastric carcinoma that infiltrates the esophagogastric junction and distal esophagus from below. Of the 335 patients undergoing resection, 110 (33%) had type I, 96 (28%) had type II, and 129 (39%) had type III. The preponderance of the male sex and the prevalence of metaplasia in distal esophagus decreased from type I to type III tumors (P<0.01). The prevalence of undifferentiated tumors increased from type I to type III tumors (P<0.01). Esophagectomy with resection of the proximal stomach for type I and extended total gastrectomy with transhiatal resection of the distal esophagus for type II and III were the primary procedures. The mean number of removed lymph node was higher in type III and II compared to type I tumors. The overall postoperative 30-day mortality was 8.4%. The death rate in transthoracic esophagectomy was higher than with extended total gastrectomy. The classification of adenocarcinoma of the esophagogastric junction into type I, II and III tumors helps in the selection of surgical approach. Type I tumors are approached as distal esophageal cancer. Type III tumors are a special form of gastric cancer and treated as a gastric cancer. The relation of type II tumors to

    Aim:Fluopsin C,an antibiotic isolated from Pseudomonasjinanesis,has shown antitumor effects on several cancer cell lines.In the current study,the oncotic cell death induced by fluopsin C was investigated in human breast adenocarcinoma cells in vitro.Methods:Human breast adenocarcinoma cell lines MCF-7 and MD-MBA-231 were used.The cytotoxicity was evaluated using MTT assay.Time-lapse microscopy and transmission electron microscopy were used to observe the morphological changes.Cell membrane integrity was assessed with propidium iodide (PI) uptake and lactate dehydrogenase (LDH) assay.Flow cytometry was used to measure reactive oxygen species (ROS) level and mitochondrial membrane potential (△ψm).A multimode microplate reader was used to analyze the intracellular ATP level.The changes in cytoskeletal system were investigated with Western blotting and immunostaining.Results:Fluopsin C (0.5-8 μmol/L) reduced the cell viability in dose-and time-dependent manners.Its IC50 values in MCF-7 and MD-MBA-231 cells at 24 h were 0.9 and 1.03 μmol/L,respectively.Fluopsin C (2 μmol/L) induced oncosis in both the breast adenocarcinoma cells characterized by membrane blebbing and swelling,which was blocked by pretreatment with the pan-caspase inhibitor Z-VAD-fmk.In MCF-7 cells,fluopsin C caused PI uptake into the cells,significantly increased LDH release,induced cytoskeletal system degradation and ROS accumulation,decreased the intracellular ATP level and△ψm.Noticeably,fluopsin C exerted comparable cytotoxicity against the normal human hepatocytes (HL7702) and human mammary epithelial cells with the IC50 values at 24 h of 2.7 and 2.4 μmol/L,respectively.Conclusion:Oncotic cell death was involved in the anticancer effects of fluopsin C on human breast adenocarcinoma cells in vitro.The hepatoxicity of fluopsin C should not be ignored.

  5. Histopathological spectrum of polymorphous low-grade adenocarcinoma

    Varun Surya

    2015-01-01

    Full Text Available Polymorphous low-grade adenocarcinomas (PLGA are distinctive salivary gland neoplasms, with an almost exclusive propensity to arise from the minor salivary glands. PLGA frequently manifests as an asymptomatic, slow-growing mass within the oral cavity, which must be separated from adenoid cystic carcinoma and benign mixed tumor for therapeutic and prognostic considerations. We report a case of a 67-year-old male, who presented with a long-standing mass in the palate. This lesion was diagnosed as PLGA based on histopathological findings, which was further confirmed by the immunohistochemical marker.

  6. Therapeutic Endoscopic Ultrasonography: Intratumoral Injection for Pancreatic Adenocarcinoma

    Lawrence A. Shirley

    2013-01-01

    Full Text Available Pancreatic adenocarcinoma is an aggressive disease that has poor outcomes despite maximal traditional therapies. Thus, treatment of this cancer demands innovative strategies to be used in addition to standing therapies in order to provide new avenues of care. Here, we describe the technique of using endoscopic ultrasound in order to directly inject both novel and conventional therapies into pancreatic tumors. We detail the rationale behind this strategy and the many benefits it provides. We then describe our technique in detail, including our experience injecting the AdV-tk adenoviral vector to create an in situ vaccine effect.

  7. SIGNET-RING MUCINOUS ADENOCARCINOMA OF THE PANCREAS

    W.H.Chow; LouisT.C.Chow

    1994-01-01

    An 88-year-old man presented symptoms and signs of ascending cholangitis and died 20 days after the onset of illness.Postmortem examination revealed a mucinous tumor arising from the head of the pancreas,encasing the common bile duct and invading the liver with multiple hepatic metastasis.The tumor showed a unique and uniform histological appearance,consisting of signet-ring neoplastic cells floating in mucin pools.The rapid clinical course and widespread hepatic metastasis of this patient suggest that this pure,signet-ring variant of mucinous adenocarcinoma of the pancreas might have a poorer prognosis.

  9. Transdiaphragmatic adrenalectomy for metastatic cervical adenocarcinoma: a technical case report

    Robert B. Dorman

    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.

    Despite the high prevalence and poor outcome of patients with metastatic lung cancer, the mechanisms of tumour progression and metastasis remain largely uncharacterized. We modelled human lung adenocarcinoma, which frequently harbours activating point mutations in KRAS1 and inactivation of the p53-pathway2, using conditional alleles in mice3–5. Lentiviral-mediated somatic activation of oncogenic Kras and deletion of p53 in the lung epithelial cells of KrasLSL-G12D/+;p53flox/flox mice initiate...

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

    2015-01-01

    Ovarian clear cell adenocarcinoma has a relatively poor prognosis among the ovarian cancer subtypes because of its high chemoresistance. Differential diagnosis of clear cell adenocarcinoma from other ovarian surface epithelial tumors is important for its treatment. Napsin A is a known diagnostic marker for lung adenocarcinoma, and expression of napsin A is reported in a certain portion of thyroid and renal carcinomas. However, napsin A expression in ovarian surface epithelial tumors has not previously been examined. In this study, immunohistochemical analysis revealed that in 71 of 86 ovarian clear cell adenocarcinoma patients (83%) and all of the 13 patients with ovarian clear cell adenofibroma, positive napsin A staining was evident. No expression was observed in 30 serous adenocarcinomas, 11 serous adenomas or borderline tumors, 19 endometrioid adenocarcinomas, 22 mucinous adenomas or borderline tumors, 10 mucinous adenocarcinomas, or 3 yolk sac tumors of the ovary. Furthermore, expression of napsin A was not observed in the normal surface epithelium of the ovary, epithelia of the fallopian tubes, squamous epithelium, endocervical epithelium, or the endometrium of the uterus. Therefore, we propose that napsin A is another sensitive and specific marker for distinguishing ovarian clear cell tumors (especially adenocarcinomas) from other ovarian tumors. PMID:24721826

  3. MiR-485 inhibits metastasis and EMT of lung adenocarcinoma by targeting Flot2.

    Mou, Xuri; Liu, Shuliang

    2016-09-01

    Lung adenocarcinoma, as a common form of non-small cell lung cancer, poses a significant threat to public health worldwide. Previous studies have reported that flotillin-2 (Flot2) is often overexpressed in various tumors and is h correlated with tumor progression and patient survival. Dysregulated microRNA (miRNA) is associated with various cancers, including lung adenocarcinoma. However, little is known about the miRNAs targeting Flot2 in lung adenocarcinoma. In this study, we found that the expression level of miR-485 was downregulated in four lung adenocarcinoma cell lines and tissues and that the reduced miR-485 expression was associated with tumor metastasis. Luciferase assay revealed that Flot2 is direct target of miR-485, while the expression levels of Flot2 were inversely correlated with the expression levels of miR-485 in lung adenocarcinoma tissues. Ectopic Flot2 could significantly reverse miR-485-mediated inhibition of metastasis and EMT, demonstrating Flot2 downregulation is involved in function of miR-485. Subsequently, we found that miR-485 suppressed the activity of PI3K/AKT/mTOR signaling in lung adenocarcinoma cells. In conclusion, the present study provided novel insight into the molecular mechanism of lung adenocarcinoma progression and demonstrating miR-485 as a potential therapeutic target in human lung adenocarcinoma.

  4. Gastroesophageal reflux in relation to adenocarcinomas of the esophagus: a pooled analysis from the Barrett's and Esophageal Adenocarcinoma Consortium (BEACON.

    Michael B Cook

    Full Text Available Previous studies have evidenced an association between gastroesophageal reflux and esophageal adenocarcinoma (EA. It is unknown to what extent these associations vary by population, age, sex, body mass index, and cigarette smoking, or whether duration and frequency of symptoms interact in predicting risk. The Barrett's and Esophageal Adenocarcinoma Consortium (BEACON allowed an in-depth assessment of these issues.Detailed information on heartburn and regurgitation symptoms and covariates were available from five BEACON case-control studies of EA and esophagogastric junction adenocarcinoma (EGJA. We conducted single-study multivariable logistic regressions followed by random-effects meta-analysis. Stratified analyses, meta-regressions, and sensitivity analyses were also conducted.Five studies provided 1,128 EA cases, 1,229 EGJA cases, and 4,057 controls for analysis. All summary estimates indicated positive, significant associations between heartburn/regurgitation symptoms and EA. Increasing heartburn duration was associated with increasing EA risk; odds ratios were 2.80, 3.85, and 6.24 for symptom durations of <10 years, 10 to <20 years, and ≥20 years. Associations with EGJA were slighter weaker, but still statistically significant for those with the highest exposure. Both frequency and duration of heartburn/regurgitation symptoms were independently associated with higher risk. We observed similar strengths of associations when stratified by age, sex, cigarette smoking, and body mass index.This analysis indicates that the association between heartburn/regurgitation symptoms and EA is strong, increases with increased duration and/or frequency, and is consistent across major risk factors. Weaker associations for EGJA suggest that this cancer site has a dissimilar pathogenesis or represents a mixed population of patients.

  5. Metastatic Pulmonary Adenocarcinoma 6 Years After Curative Resection for Ampullary Adenocarcinoma. Metastatic Disease from Initial Primary or Metachronous Tumour?

    Alexandros Giakoustidis

    2011-01-01

    Full Text Available Context With patients surviving longer after pancreatic resection, the challenges now is the management of the unresolved longerterm issues. Case report A 53-year-old woman with painless obstructive jaundice, underwent a pylorous preserving pancreaticoduodenectomy for a pT3N0M0 ampullary adenocarcinoma in 2001 (patchy chronic pancreatitis with mucinous metaplasia of background pancreatic duct epithelium and acinar atrophy were noted. Despite adjuvant chemotherapy, at month 54 she required a pulmonary wedge resection for metastatic adenocarcinoma, followed by a pulmonary relapse at 76 months when she underwent 6 neoadjuvant cycles of gemcitabine/capecitabine and a left pneumonectomy. Finally 7 years after the initial Whipple’s, a single 18F fluorodeoxyglucose (FDG avid pancreatic tail lesion led to completion pancreatectomy for a well-differentiated ductal adenocarcinoma with clear resection margins albeit peripancreatic adipose tissue infiltration. On review all resected tumour cells had identical immunophenotype (CK7+/CK20-/MUC1+/MUC2- as that of the primary. She is currently asymptomatic on follow-up. Conclusions These findings suggest that in selected cases even in the presence of pulmonary metastasis, repeat resections could result in long-term survival of patients with metachronous ampullary cancer. Second, even ampullary tumours maybe should be regarded as index tumors in the presence of ductal precursor lesions in the resection specimen. Three distant metastases, particularly if long after the initial tumour, should instigate a search for metachronous tumour, especially in the presence of field change in the initial specimen. Risk-adapted follow-up protocols with recognition of such factors could result in cost-effective surveillance and potentially improved outcomes.

  6. Leptomeningeal metastases of esophagogastric junction adenocarcinoma - case report and treatment review

    Oesophagogastric junction adenocarcinoma usually disseminates to the abdominal lymph nodes, peritoneum (peritoneal carcinomatosis) or with blood to the distant organs (such as liver, lung, bones or central nervous system); leptomeningeal metastases are rare. A case report of a 49-year-old male with disseminated oesophagogastric junction adenocarcinoma (with liver, abdominal lymph nodes and leptomeningeal metastases) is presented. As a clinical representation progressive dysfunction of the central and peripheral nervous system has been observed. Patterns of failure of gastric adenocarcinoma treatment and clinical value of prognostic factors are evaluated. Oesophagogastric junction adenocarcinoma dissemination and leptomeningeal metastases diagnostic and treatment capabilities are discussed. Conclusions: Leptomeningeal metastases of oesophagogastric junction adenocarcinoma are rare and available treatment (radiotherapy, chemotherapy - systemic or local) is inefficient. (authors)

  7. Case report: late perianal mucinous adenocarcinoma after Crohn's disease proctectomy: an oncological rarity

    Gladisch Rainer

    2005-06-01

    Full Text Available Abstract Background As in ulcerative colitis, there is an increased incidence of colorectal carcinoma in Crohn's disease. While carcinoma formation originating from ano-rectal fistulas is generally considered as a rare event there are different publications reporting on mucinous adenocarcinoma formation in association with a neovagina and rectovaginal fistulas. To the best of our knowledge this is the first description of a perianal mucinous adenocarcinoma arising in a patient after Crohn's disease proctocolectomy. Case presentation We report the case of a 50-year old female with a mucinous adenocarcinoma forming in the perineum eleven years after proctocolectomy for Crohn's disease. The patient was readmitted with perineal pain, leucocytosis and a perineal mass highly suspicious of abscess formation in the MRI-Scan. Histological examination revealed a mucinous adenocarcinoma. Exenteration including vagina, uterus and ovaries together with the coccygeal-bone was performed. Conclusion Mucinous adenocarcinoma formation is a rare complication of Crohn's disease and so far unreported after proctocolectomy.

  17. Neurinoma del plexo braquial simulando metastasis de adenocarcinoma de mama Schwannoma of the brachial plexus resembling a breast adenocarcinoma metastasis

    Gregorio Rodríguez Boto

    2011-10-01

    Full Text Available Los neurinomas del plexo braquial son tumores infrecuentes que pueden confundirse con otras lesiones de índole tumoral. Se presenta el caso de una mujer de 40 años, tratada previamente de un adenocarcinoma de mama derecha en el pasado, que en el estudio de extensión realizado 5 años después se detectó una lesión localizada en el plexo braquial derecho. La paciente se encontraba asintomática. El diagnóstico radiológico de presunción fue metástasis de adenocarcinoma mamario. Se realizó un abordaje axilar derecho descubriendo una lesión bien delimitada en el plexo braquial. Con ayuda de la monitorización neurofisiológica intraoperatoria, se observó que la lesión dependía de la rama cubital y se pudo realizar una resección completa preservando la función de dicho nervio. El estudio anatomopatológico confirmó que se trataba de un neurinoma, descartando así la existencia de metástasis. La evolución postoperatoria fue satisfactoria. Seis años después de la intervención no existe recidiva tumoral. En nuestro conocimiento este es el primer caso publicado en la literatura de un neurinoma del plexo braquial dependiente de la rama cubital. La monitorización neurofisiológica intraoperatoria resulta fundamental para abordar este tipo de lesiones con baja morbilidad.Schwa nomas originating from the brachial plexus, although rare, may be mistaken for another type of tumour. A 40 year-old woman, who had been treated years earlier for a breast adenocarcinoma, showed in the 5-year follow-up magnetic resonance examination a localized lesion in the right brachial plexus. The presumptive radiological diagnosis was a metastasis from the primary adenocarcinoma. Following surgical access via the right axilla, a well-circumscribed mass in the brachial plexus was detected. Under intraoperative electrophysiological guidance, the lesion was observed to depend on the ulnar nerve and its complete resection was possible without compromising nerve

  18. Prognostic value of preoperative FDG-PET in stage IA lung adenocarcinoma

    Background: Maximum standardized uptake value (SUVmax) of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) has been found to have prognostic value. We previously reported the correlation between SUVmax and pathological invasive area, and determined an SUVmax cut-off value of 2.15 for predicting the recurrence potential of an invasive area of diameter 5 mm. Here, we evaluate the validity of FDG-PET for prediction of recurrence in pathological stage IA lung adenocarcinoma. Methods: From February 2006 to May 2008, 100 patients with pathological stage IA lung adenocarcinoma underwent complete resection at our hospital. Tumors were classified as air-type or solid-type based on thin-section computed tomography (TS-CT) findings and the influence of TS-CT classification, SUVmax, and clinicopathologic features were evaluated in terms of the incidence of recurrence. Results: Unlike air-type adenocarcinomas, recurrent disease was detected in 8 of 62 solid-type adenocarcinomas. SUVmax and diameter of invasive area were significantly correlated with recurrence and a shorter time to recurrence. All 8 recurrent cases had pathological invasive area >5 mm. All except one case of recurrence were solid-type adenocarcinomas with SUVmax ≥ 2.15. Three-year disease-free survival rates were 100% in air-type adenocarcinomas, 97.1% in solid-type adenocarcinomas with SUVmax < 2.15, and 74.1% in solid-type adenocarcinoma with SUVmax ≥ 2.15. Conclusion: Combined evaluation of TS-CT classification and SUVmax had significant value in predicting recurrence in stage IA lung adenocarcinoma, reflecting the aggressiveness of primary lung adenocarcinoma. Prediction of tumor aggressiveness could contribute to decision-making regarding the choice of surgical procedure and treatment after surgery.

  20. Clear Cell Adenocarcinoma of the Urethra: Review of the Literature

    Anthony Kodzo-Grey Venyo

    2015-01-01

    Full Text Available Background. Clear cell adenocarcinoma of the urethra (CCAU is extremely rare and a number of clinicians may be unfamiliar with its diagnosis and biological behaviour. Aims. To review the literature on CCAU. Methods. Various internet databases were used. Results/Literature Review. (i CCAU occurs in adults and in women in the great majority of cases. (ii It has a particular association with urethral diverticulum, which has been present in 56% of the patients; is indistinguishable from clear cell adenocarcinoma of the female genital tract but is not associated with endometriosis; and probably does not arise by malignant transformation of nephrogenic adenoma. (iii It is usually, readily distinguished from nephrogenic adenoma because of greater cytological a-typicality and mitotic activity and does not stain for prostate-specific antigen or prostatic acid phosphatase. (iv It has been treated by anterior exenteration in women and cystoprostatectomy in men and at times by radiotherapy; chemotherapy has rarely been given. (v CCAU is aggressive with low 5-year survival rates. (vi There is no consensus opinion of treatment options that would improve the prognosis. Conclusions. Few cases of CCAU have been reported. Urologists, gynaecologists, pathologists, and oncologists should report cases of CCAU they encounter and enter them into a multicentric trial to determine the best treatment options that would improve the prognosis.

  1. A report of disseminated adenocarcinoma presenting as thrombotic thrombocytopenic purpura

    Joaquín Valle Alonso

    2011-10-01

    Full Text Available Thrombotic microangiopathies (TMAs represent a heterogeneous group of diseases characterized by a microangiopathic hemolytic anemia, peripheral thrombocytopenia, and organ failure of variable severity. TMAs encompass thrombotic thrombocytopenic purpura (TTP, typically characterized by fever, central nervous system manifestations and hemolytic uremic syndrome (HUS, in which renal failure is the prominent abnormality. In patients with cancer TMAs may be related to various antineoplastic drugs or to the malignant disease itself. The reported series of patients with TMAs directly related to cancer are usually heterogeneous, retrospective, and encompass patients with hematologic malignancies with solid tumors or receiving chemotherapy, each of which may have distinct presentations and pathophysiological mechanisms. Patients with disseminated malignancy who present with microangiopathic hemolytic anemia and thrombocytopenia may be misdiagnosed as thrombotic thrombocytopenic purpura (TTP. Only a few cases of TTP secondary to metastatic adenocarcinoma are known in the literature. We present a case of a 34-year-old man with TTP syndrome secondary to metastatic small-bowel adenocarcinoma. Patients with disseminated malignancy had a longer duration of symptoms, more frequent presence of respiratory symptoms, higher lactate dehydrogenase levels, and more often failed to respond to plasma exchange treatment. A search for systemic malignancy, including a bone marrow biopsy, is appropriate when patients with TTP have atypical clinical features or fail to respond to plasma exchange.

    2015-03-15

    Objective: To evaluate the role of multidetector computed tomography in the preoperative investigation of tumor invasion depth and lymph node and metastatic involvement according to the TNM classification, in patients with gastric adenocarcinoma. Materials and Methods: Fifty-four patients with biopsy-confirmed gastric cancer underwent preoperative staging with 64-channel multidetector computed tomography. Two independent radiologists analyzed the images and classified the findings. Sensitivity, specificity, accuracy and overall accuracy were calculated for each observer. The interobserver agreement was also evaluated. Results: The accuracy in the classification of categories T ranged from 74% to 96% for observer 1 and from 80% to 92% for observer 2. The overall accuracy was 70% for both observers. The weighted kappa index was 0.75, consistent with a significant interobserver agreement. The accuracy in the classification of lymph node involvement (category N) ranged from 55% to 79% for observer 1 and from 73% to 82% for observer 2. The evaluation of metastatic involvement showed an overall accuracy of 89.6% for both observers. Conclusion: 64-channel multidetector computed tomography demonstrated clinically relevant accuracy in the preoperative staging of gastric adenocarcinoma as regards invasion depth (T category) and metastatic involvement (M category).

  3. PNMA1 promotes cell growth in human pancreatic ductal adenocarcinoma.

    Jiang, Shu-Heng; He, Ping; Ma, Ming-Ze; Wang, Yang; Li, Rong-Kun; Fang, Fang; Fu, Ying; Tian, Guang-Ang; Qin, Wen-Xin; Zhang, Zhi-Gang

    2014-01-01

    Paraneoplastic Ma1 (PNMA1) is a member of an expanding family of 'brain/testis' proteins involved in an autoimmune disorder defined as paraneoplastic neurological syndrome (PNS). Although it is widely studied in PNS, little is known about the underlying clinical significance and biological function of PNMA1 in tumors. Here, we find that elevated PNMA1 expression is more commonly observed in pancreatic ductal adenocarcinoma (PDAC) cell lines, compared with normal pancreatic cell and tissues from pancreatic ductal adenocarcinoma patient. Besides, higher PNMA1 expression is closely correlated with large tumor size. Suppression of endogenous PNMA1 expression decreases cell viability and promotes cell apoptosis. Subsequent studies reveal that the PI3K/AKT, MAPK/ERK pathway and members of the anti-apoptotic Bcl-2 family may be involved in the pro-survival and anti-apoptotic effect of PNMA1 on PDAC. Taken together, this study provides evidence that PNMA1 is involved in tumor growth of pancreatic carcinoma and PNMA1-related pathways might represent a new treatment strategy. PMID:25120759

  4. Bladder metastases of appendiceal mucinous adenocarcinoma: a case presentation

    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. 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. 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

    2011-06-01

    Full Text Available Abstract Introduction Henoch-Schönlein purpura is a common immunoglobulin A-mediated vasculitis syndrome in children. Henoch-Schönlein purpura can also affect adults and is probably related to malignancy. Case presentation We report the case of a 61-year-old Japanese man who presented for examination after an abnormal shadow was detected by chest radiography. He received a diagnosis of pulmonary adenocarcinoma, stage IV. Purpura on the legs, abdominal pain, diarrhea, hematuria and proteinuria developed at this time. Henoch-Schönlein purpura was diagnosed, base on the clinical symptoms and histological findings of biopsy specimens of the skin, which showed vasculitis with immunoglobulin A deposits. Our patient received chemotherapy with gemcitabine after successful steroid therapy for the Henoch-Schönlein purpura. Conclusion Although hematological malignancies are well-known causes of vasculitides, cases of Henoch-Schönlein purpura associated with lung adenocarcinoma are rare. Our patient was treated with corticosteroid therapy, which cleared the purpura and cytotoxic chemotherapy for the non-small cell lung cancer. However, he died from heart failure due to cardiac tamponade.

  6. Primary Breast Adenocarcinoma in Ectopic Breast Tissue in the Vulva

    Jason McMaster

    2013-01-01

    Full Text Available Introduction. Accessory breast tissue is a rare finding in the general population with an incidence of 1-2%. An even rarer occurrence is accessory breast tissue afflicted with breast carcinoma. We present a brief report discussing diagnosis and management of a patient who presented with primary breast adenocarcinoma in vulval supranumerary tissue. Brief Report. A 60-year-old Caucasian female presented with a lesion in her left vulva that she first identified during adolescence. The lesion began to grow and ulcerate prompting her to receive treatment. Biopsy was inconclusive, and metastatic workup was negative, so her lesion was treated as an isolated breast lump and removed via wide local excision. Conclusion. Primary breast adenocarcinoma of the vulva is exceedingly rare. A paucity of the literature on this topic unfortunately means that strong evidence does not exist detailing the best management of this patient cohort. However, given that histological data confirms these cancers are virtually the same as breast cancers, it logically follows that the best treatment practices for breast cancer may be applied to treat these patients presenting with primary vulva cancers of ectopic breast tissue.

  7. A pure microcytic bladder carcinoma synchronous to prostatic adenocarcinoma.

    Vasileios Rombis

    2011-07-01

    Full Text Available Small cell carcinoma (SCC or microcytic carcinoma of the urinary bladder is a rare entity comprising approximately 0.5% of all bladder tumors. Due to its rarity, no prospective studies evaluating the most effective treatment have been published in the medical literature. Several cases of bladder SCC have been presented so far. We describe our case report and we revise the recent literature. Our patient was diagnosed with pure bladder SCC and prostatic adenocarcinoma. After the initial and complete transurethral resection of the bladder tumour (TUR-BT, he underwent a thorax and mediastinum computer tomography (CT examination to exclude primary pulmonary small cell carcinoma and a bone scan scintigraphy for staging purposes. He received a three 14-day cycles of Cisplatin-containing chemo - therapeutic schema and a single dose of Luteinizing-Hormone Releasing hormone (LHRH analogue injection after 14 days of bicalutamide administration. The patient is followed for 24 months without any signs of bladder SCC recurrence or biochemical or local relapse from prostatic adenocarcinoma.

  8. Metastatic Adenocarcinoma Presenting as Extensive Cavoatrial Tumor Thrombus

    The presence of tumor thrombus in the right atrium is frequently the result of direct intraluminal extension of infra-diaphragmatic malignancy into the inferior vena cava (IVC) or supradiaphragmatic carcinoma into the superior vena cava (SVC). Right atrial tumor thrombus with extension into both SVC and IVC has not been reported in the literature. We present a patient who presented with symptoms of right atrial and SVC obstruction. Imaging revealed presence of a thrombus in the right atrium, extending to the SVC and IVC, with the additional findings of a left adrenal mass and multiple liver lesions. The histopathological examination of the right atrial mass revealed metastatic adenocarcinoma cells. The patient was given a presumptive diagnosis of metastatic adenocarcinoma, most likely adrenal in origin, with multiple hepatic lesions suspicious for metastasis. The clinical outcome of the patient was not favorable; the patient succumbed before the adrenal mass could be confirmed to be the primary tumor. This case highlights that in patients manifesting with extensive cavoatrial thrombus as, the existence of primary carcinoma should be considered especially in the adrenal cortex or in the lung

  9. Primary duodenal adenocarcinoma: case report of an infrequent tumor

    Óscar Moreno-Loaíza

    2013-10-01

    Full Text Available Introduction. Primary duodenal adenocarcinoma is an infrequent tumor both in our environment and in the world. There is no conclusive evidence on its epidemiology, diagnostic criteria, treatment or prognosis. Clinical case. We report a 77 year-old female patient, of mixed racial origin, native of Cusco (Peru who consulted for abdominal pain, weight loss, nausea, postprandial vomiting and bloating of three months course. At the time of examination she had second to third degree protein malnutrition with a BMI of 16.88 kg/m2, signs of moderate to severe chronic anemia and an 8 cm abdominal tumor in the epigastrium and right hypochondrium. The multislice spiral abdominal CT and ultrasonography revealed the presence of a solid tumor in the second portion of the duodenum. The patient was submitted to a gastroenterostomy without tumor resection. Biopsy confirmed tubular adenocarcinoma. Furthermore, no other primary tumors were found in the stomach, pancreas, biliary tree and colon. The patient was stabilized and was treated with 5-fluorouracil, irinotecan and leucovorin. Literature review. The article includes a brief review on the diagnosis, treatment and prognosis of this condition. Discussion. Management is not straightforward. There is little literature on the subject leaving decisions up to the attending physician’s criteria. We believe that all cases of rare diseases should be studied in depth, give rise to a thorough review of literature and, above all, be brought to the attention of the medical community.

A paucity of the literature on this topic unfortunately means that strong evidence does not exist detailing the best management of this patient cohort. However, given that histological data confirms these cancers are virtually the same as breast cancers, it logically follows that the best treatment practices for breast cancer may be applied to treat these patients presenting with primary vulva cancers of ectopic breast tissue.

    Full Text Available Hepatoid adenocarcinoma of the stomach (HAS is a rare form of gastric cancer that has unique clinicopathological features and an extremely poor prognosis. Here, we report on three patients with suspected gastric cancer who were referred to our hospital. Gastrointestinal fiberscopy on the three patients revealed two lesions in the antrum and a third lesion in the gastroesophageal junction. The alpha fetoprotein (AFP serum levels were markedly elevated in all cases. At the time of diagnosis, two cases were advanced stages with lymph nodes and/or liver metastases. Two patients underwent exploratory laparotomy. A total gastrectomy was performed on the operable lesion, and an expanded gastrectomy was completed in the case with hepatic metastases. Histopathological analysis revealed that the tumors displayed two pathological changes: hepatoid-like foci and adenocarcinomatous. Furthermore, the tumor cells were immunohistochemically positive for AFP, alpha-1 antitrypsin, and alpha-1 antichymotrypsin. All three patients received chemotherapy. The follow-up duration ranged from 8-36 mo. Our experience and previous published studies have suggested that HAS is an aggressive type of adenocarcinoma. However, radical surgery and chemotherapy may positively impact clinical outcomes.

    Full Text Available Introduction. Adenocarcinoma of the small bowel is a rare gastrointestinal neoplasm usually affecting the distal duodenum and proximal jejunum. Because of their rarity and poorly defined abdominal symptoms, a correct diagnosis is often delayed. Case Outline. We present a 43-year-old woman admitted at the Clinic for Endocrinology due to a large tumor (over 7 cm of the left adrenal gland. The tumor was detected by ultrasound and confirmed by CT scan. The patient complained of abdominal pain in the left upper quadrant, fatigue and septic fever. Normal urinary catecholamines excluded pheochromocytoma. The endocrine evaluations revealed laboratory signs of subclinical hypercorticism: midnight cortisol 235 nmol/L, post 1 mg - overnight Dexamethasone suppression test for cortisol 95.5 nmol/L and basal ACTH 4.2 pg/mL. Plasma rennin activity and aldosterone were within the normal range. Surgery was performed. Intraoperative findings showed signs of acute peritonitis and a small ulceration of the jejunum below at 70 cm on the anal side from the Treitz’s ligament. Adrenal glands were not enlarged. Patohistology and immunochemistry identified adenocarcinoma of the jejunum without infiltration of the lymphatic nodules. The extensive jejunal resection and lavage of the peritoneum were performed. Due to complications of massive peritonitis, the patient died seven days after surgery. Conclusion. Poorly defined symptoms and a low incidence make the diagnosis of small bowel carcinoma, particularly of the jejunal region, very difficult in spite of the new endoscopic techniques.

    AIM: To investigate the differently expressed genes in human colorectal adenocarcinoma.METHODS: The integrated approach for gene expression profiling that couples suppression subtractive hybridization, high-throughput cDNA array, sequencing,bioinformatics analysis, and reverse transcriptase realtime quantitative polymerase chain reaction (PCR)was carried out. A set of cDNA clones including 1260SSH inserts amplified by PCR was arrayed using robotic printing. The cDNA arrays were hybridized with florescent-labeled probes prepared from RNA of human colorectal adenocarcinoma (HCRAC) and normal colorectal tissues.RESULTS: A total of 86 genes were identified, 16 unknown genes and 70 known genes. The transcription factor Sox9 influencing cell differentiation was downregulated. At the same time, Heat shock protein 10 KDis downregulated and Calmoulin is up-regulated.CONCLUSION: Downregulation of heat shock protein 10 KD lost its inhibition of Ras, and then attenuated the Ras GTPase signaling pathway, increased cell proliferation and inhibited cell apoptosis. Down-regulated transcription factor Sox9 influences cell differentiation and cell-specific gene expression. Down-regulated Sox9 also decreases its binding to calmodulin, accumulates calmodulin as receptor-activated kinase and phosphorylase kinase due to the activation of PhK.

    MicroRNAs (miRNAs) can serve as biomarkers in human cancer. To determine the clinical value of urinary miRNAs for ovarian serous adenocarcinoma, we collected urine samples from 39 ovarian serous adenocarcinoma patients, 26 patients with benign gynecological disease and 30 healthy controls. The miRNA microarray data showed that only miR-30a-5p was upregulated and 37 miRNAs were downregulated in the urine samples of ovarian serous adenocarcinoma patients, when compared to healthy controls, which was confirmed after conducting quantitative PCR. The upregulation of urinary miR-30a-5p was closely associated with early stage of ovarian serous adenocarcinoma as well as lymphatic metastasis. Receiver operator characteristic (ROC) analysis demonstrated the potential use of urinary miR-30a-5p as a diagnostic marker for ovarian serous adenocarcinoma. Furthermore, a lower urine level of miR-30a-5p was found in 20 gastric cancer and 20 colon carcinoma patients when compared to ovarian serous adenocarcinoma, suggesting that the upregulation of urinary miR-30a-5p may be specific for ovarian serous adenocarcinoma. miR-30a-5p was also upregulated in ovarian serous adenocarcinoma tissues and cell lines, while urinary miR-30a-5p from ovarian cancer patients was notably reduced following the surgical removal of ovarian serous adenocarcinoma, suggesting that urinary miR-30a-5p was derived from the ovarian serous adenocarcinoma tissue. Notably, miR-30a-5p was concentrated with exosomes from the ovarian cancer cell supernatant or urine from ovarian serous adenocarcinoma patients, supporting a pathway for excretion into the urine. The results also showed that the knockdown of miR-30a-5p significantly inhibited the proliferation and migration of ovarian cancer cells. In summary, to the best of our knowledge, the present study provided the first evidence of increased miR-30a-5p in the urine of ovarian serous adeno-carcinoma patients, while the inhibition of miR-30a-5p suppressed the

    Full Text Available A esofagite de refluxo associada ao epitélio de colunar do esôfago predispõe ao adenocarcinoma, cuja incidência vem aumentando nos últimos anos. Entre 1976 e 1993, os autores trataram 11 pacientes com adenocarcinoma primário do esôfago. Em dois casos, a neoplasia desenvolveu-se em epitélio colunar ectópico no esôfago cervical e torácico. Nos demais casos, ocorreu no terço distal do esôfago em epitélio colunar de Barrett, em pacientes com sintomas clínicos de esofagite de refluxo, dos quais sete eram portadores de hérnia de hiato e refluxo gastroesofágico previamente documentados. Nove pacientes foram submetidos a esofagectomia transiatal com esofagogastroplastia, um foi submetido a esofagectomia distal com interposição de jejuno e o último a esofagogastroplastia retroestemal sem esofagectomia. A exceção de três pacientes, os demais tiveram operações consideradas curativas. Cinco doentes encontravam-se em estádios mais iniciais, ainda sem comprometimento linfonodal. Não houve mortalidade operatória, sendo que as principais complicações foram a fístula da anastomose esofagogástrica e a abertura da cavidade pleural, ambas ocorrendo em dois pacientes. A sobrevida média dos pacientes foi de 40,5 meses. Três pacientes permanecem vivos e sem evidência de doença (estádio 0, I e IIA com 64, 94 e 117 meses de seguimento. Concluiu-se que a esofagectomia neste tipo de tumor é um procedimento seguro e que a sobrevida a longo prazo é possível quando os tumores em estadio inicial são tratados adequadamente.Esophagitis associated with Barretts esophagus is a recognized predisponent factor for the development of adenocarcinoma. its incidence has been raising through the last years.

    Background Hepatoid adenocarcinoma of the stomach (HAS) is a rare type of gastric carcinoma, which has its unique clinicopathological features and poorer prognosis than that of the ordinary gastric adenocarcinoma. At present, there is still a lack of understanding about this disease. The current study aimed to summarize and discuss the clinical,pathological, immunohistochemical, and prognostic features of this disease.Methods A total of 20 patients of HAS were retrospectively studied. All the patients were treated in Cancer Hospital of Chinese Academy of Medical Sciences between March 1998 and October 2009. Statistical analysis, including the Kaplan-Meier method, log-rank test and Cox model, were performed by the SPSS 15.0 software.Results Seventeen patients (85%) had at least 1 lymph node metastases; 17 patients (85%) received postoperative immunohistochemical examinations, with an alpha-fetoprotein (AFP) positive rate of 94.1% (16/17); 14 patients had distant metastases (including 12 liver metastases, 1 lung metastasis, and 1 celiac widespread metastases), and one simultaneously had anastomotic recurrence and liver metastases. The overall survival time was 2-99 months (median:12.0 months). The 3-year survival rate of the 20 patients was 17.2%. The 3-year survival rate of patients with complete hepatocyte-like regions and those with both hepatocellular carcinoma and adenocarcinoma regions was 20.0% and 17.5%, respectively (P=0.361). The survival difference among the radical surgery group, palliative surgery group and no surgery group was statistically significant (P=0.022). The Kaplan-Meier method and log-rank test showed that surgery,pTNM stages, and adjuvant chemotherapy were associated with prognosis (P <0.05). The Cox model only confirmed that the pTNM stages and adjuvant chemotherapy had statistical significance for the prognosis of HAS (P<0.05) due to the limited cases.Conclusions HAS is a special type of gastric carcinoma and has a poor prognosis.

    The osmoregulated transcription factor nuclear factor of activated T-cells 5(NFAT5), has been found to play important roles in the development of many kinds of human cancers, including breast cancer, colon carcinoma, renal cell carcinoma and melanoma. The aim of the present study was to determine whether NFAT5 is involved in the proliferation and migration of lung adenocarcinoma cells. We found that NFAT5 was upregulated in lung adenocarcinoma cells and knockdown of NFAT5 decreased proliferation and migration of the cells, accompanied by a significant reduction in the expression of AQP5. AQP5 was upregulated in lung adenocarcinoma cells and knockdown of AQP5 also inhibited proliferation and migration of the cells as knockdown of NFAT5 did. Moreover, overexpression of NFAT5 promoted proliferation and migration of lung adenocarcinoma cells, accompanied by a significant increase in the expression of AQP5. These results indicate that NFAT5 plays important roles in proliferation and migration of human lung adenocarcinoma cells through regulating AQP5 expression, providing a new therapeutic option for lung adenocarcinoma therapy. - Highlights: • NFAT5 expression is higher in lung adenocarcinoma cells compared with normal cells. • NFAT5 knockdown decreases proliferation and migration of lung adenocarcinoma cells. • Knockdown of NFAT5 reduces AQP5 expression in human lung adenocarcinoma cells. • Overexpression of NFAT5 promotes proliferation and migration of lung adenocarcinoma cells. • Overexpression of NFAT5 increases AQP5 expression in human lung adenocarcinoma cells.

    A new lung adenocarcinoma classification was recently proposed by IASLC/ATS/ERS. In this classification, invasive mucinous adenocarcinoma (IMC) is placed in a new category because of its unique radiologic, morphologic, and genetic characteristics. Minimal cytologic atypia characterizes this tumor; thus, it is occasionally difficult to make a diagnosis with a biopsy specimen. We used immunohistochemistry to examine HNF4α expression in a tissue microarray consisting of 278 lung adenocarcinoma specimens. In addition, we analyzed the clinicopathologic features, including EGFR, KRAS, and ALK mutation status. HNF4α expression was detected in 33 of the 37 surgically resected IMCs. The tumor cells were uniformly labeled with the molecule in all of the corresponding biopsy specimens, whereas the normal cells were not. Although HNF4α was also expressed in other lung adenocarcinoma subtypes, those with HNF4α expression shared IMC features, including negative TTF-1 expression (P<0.001), positive CDX2 expression (P<0.001), positive KRAS mutation status (P=0.001), and negative EGFR mutation status (P<0.001). Although some ALK-positive adenocarcinomas showed IMC morphology, the tumors were negative for HNF4α, suggesting that they belonged to a different group of tumors. We found that HNF4α labeled all of the IMC tumors except the ALK-positive adenocarcinomas. Thus, HNF4α positivity could serve as a useful marker for overcoming the diagnostic difficulties caused by minimal nuclear atypia and sparse tumor cells in small biopsy samples. Because other adenocarcinoma subtypes with HNF4α expression share clinicopathologic features with IMC, these adenocarcinomas, especially the columnar cell type of acinar-predominant adenocarcinoma, might constitute a biological spectrum of IMC.

Methods: RNA extracted from three paired pulmonary adenocarcinoma tissue and adjacent noncancerous tissue specimens was used to synthesize double-stranded complementary DNA after labeling and hybridization. The complementary DNA was labeled and hybridized to the lncRNA expression microarray, and array data were analyzed for hierarchical clustering. Gene coexpression networks were constructed to identify interactions among genes. To validate the microarray findings, we measured the relative expression levels of four random differentially expressed lncRNAs in the same tissue used for microarray using real-time quantitative polymerase chain reaction. The expression level of one lncRNA, AK124939, in the paired pulmonary adenocarcinoma/adjacent noncancerous tissue of another 30 patients was measured using real-time quantitative polymerase chain reaction. The experimental data were further analyzed and compared with clinical features. Results: Of 39,000 lncRNAs investigated, 704 were differentially expressed in pulmonary adenocarcinoma tissue; 385 were upregulated and 319 were downregulated compared with those in the adjacent noncancerous tissue (fold change ≥2 and ≤–2, P<0.05. AK124939 expression levels in poorly differentiated adenocarcinoma tissue were lower than those found in well to moderately differentiated adenocarcinoma tissue (P=0.05. Conclusion: There are significant differences in the lnc

    Galactose oxidase method was employed to detect the beta-D-Gal (1-->3) -D-Gal NAc residue of T-antigen present in the large intestinal mucus of 156 subjects. The positive rates of the test were 84.4%, 29.1%, and 7.2% in the mucus samples obtained from 32 patients with colorectal adenocarcinomas, 55 with polyps and 69 controls respectively. Chi-square test demonstrated that there were significant differences between the group of carcinoma and control (P < 0.001) as well as between also polyp and control (P < 0.01). The test had a high sensitivity (84.4%) and specificity (92.8%) in the diagnosis of colorectal cancer and may be used as a practical mass screening test for colorectal neoplasms. PMID:8731834

    Endometrial cancer is the third most common gynecologic cancer in the Korea and occurs mainly in menopausal women. Although it can develop in young premenopausal women cancer as well, an attack in the adolescent girl is very rare. A 13-year-old girl visited gynecology department with the complaint of abnormal uterine bleeding. An endometrial biopsy revealed FIGO (International Federation of Gynecology and Obstetrics) grade II endometrial adenocarcinoma. In the treatment of endometrial cancer, conservative management should be considered if the patient is nulliparous or wants the fertility preservation. Therefore, we decided to perform a hormonal therapy and a follow-up endometrial biopsy after progestin administration for eight months revealed no residual tumor. We report a case of endometrial cancer occurred in a 13-year-old girl with a brief review of the literature. PMID:27004208

    2012-02-01

    We report an unusual case of Clostridium septicum aortitis with associated adenocarcinoma of the sigmoid colon. An 87-year-old man with multiple medical comorbidities presented with a 1-week history of severe abdominal pain in the left lower quadrant of his abdomen. Abdominal computed tomography showed, in addition to a mass in the sigmoid colon, a gas density within the wall of the abdominal aorta with extensive periaortic fat stranding and some additional gas densities in the proximal left common iliac artery. The patient refused surgery, and was treated with intravenous antibiotics. He died 5 weeks later. The development of Clostridiumsepticum aortitis, an extremely rare but life-threatening infection, is highly associated with an underlying colonic malignancy and demands immediate surgical intervention.

    A middle aged man presented with clinical signs of chronic meningitis, including bilateral hearing loss and progressive blindness. Lumbar puncture revealed a mild elevation in lymphocyte number, an elevation in protein levels, and diminished glucose levels, without malignant cells. Magnetic resonance imaging (MRI) T2 weighted seqeunces showed bilateral enhancement of the acoustic nerves. The aetiology of the chronic meningitis was revealed gastric cancer by gastroscopy, and micrometastasis by bone marrow trephine biopsy. Although cerebrospinal fluid (CSF) cytology was negative, neoplastic meningitis (NM) was diagnosed based on clinical and MRI data. The patient's condition worsened rapidly and he died shortly thereafter. Autopsy confirmed the presence of advanced gastric cancer (adenocarcinoma of signet-ring cell type) with pancreatic involvement, and NM with cancer cells on the meninges, but without infiltration tumour cells into underlying brain parenchyma. We conclude that NM as an initial symptom of gastric cancer is rare and ultimately fatal. PMID:21785656

    2014-05-01

    Full Text Available Ectopic prostatic tissue and seminal vesicle at pericolic fat is extremely rare. The nodules in the pericolic fat could raise a dilemma of metastatic deposits in cases of rectal adenocarcinoma. A 61 years old male underwent abdomino-perineal resection for rectal carcinoma. Nodules along with lymph nodes from pericolic fat were sampled to assess the spread. Histopathological and immunohistochemical staining of one nodule confirmed it to be the prostatic tissue while another nodule to be seminal vesicle. Seminal vesicle and prostatic heterotopia is significant in several respects, either symptomatic or asymptomatic, as the ectopic tissue can be endoscopically and histologically confused with malignancy of urinary or lower gastrointestinal system and may reflect divergent differentiation or a malformative process.

    Full Text Available Pancreatic cancer remains a significant cause of morbidity and mortality. While increasing treatment options have improved outcomes for many patients, they have also complicated decision-making for treatment. Unfortunately, most patients with pancreatic cancer die from their disease. Prognostic and predictive markers could play a role to improve treatment by identifying patients who may or may not require a given therapy, and determining those most likely to benefit from a therapy. At the 2011 American Society of Clinical Oncology (ASCO Gastrointestinal Cancers Symposium held in San Francisco, January 2011, several interesting abstracts were presented that focused on prognostic and predictive markers associated with pancreatic adenocarcinomas. These abstracts discuss progress made in identifying molecular subtypes of pancreatic cancers that may provide insight into selection of patients likely to benefit from certain therapies.

    Full Text Available PET-CT scan has demonstrated to be very effective in lung cancer diagnosis and staging, but lung cancer has multiple ways of presentation, which can lead to an error in diagnosis imaging and a delay on the beginning of specific treatment. We present a case of a 77-year-old man with an initial PET-CT scan showing high 18F-FDG intake, suggesting a bilateral pneumonia, who was finally diagnosed of an EGFR-mutant lung adenocarcinoma. EGFR-activating mutation allowed us to start treatment with the oral tyrosin kinase inhibitor Gefitinib, obtaining a rapid and sustained response. Histological confirmation of imaging findings is always necessary to avoid diagnostic errors.

  8. Vater's ampulla adenocarcinoma. A propos of a case

    99 % of the Vater's ampulla malignant tumours are carcinomas. They are infrequent and of difficult diagnosis, because there is a concurrence in the area of pancreatic diseases, of the distal third of the common bile duct, of the pancreatic duct and the adjacent duodenal mucosa diseases. The term ampullar carcinoma refers not only to a topographic location but also to their histological origin; because it implies that it derives from the intestinal mucosa that coats the region. We deal with a case diagnosed at the Teaching Military Hospital Dr. Mario Munnoz Monroy, of Matanzas, assisting the hospital with an icteric syndrome. After making an endoscopic retrograde cholangiography with biopsy, ultrasound and abdominal tomography, we arrived to the diagnosis of a Vater's ampulla mucoproductor adenocarcinoma. The patient received a radical surgery with successful results

  9. Targeting hyaluronan for the treatment of pancreatic ductal adenocarcinoma

    Norihiro Sato

    2016-03-01

    Full Text Available Progression of cancer is often associated with interactions between cancer cells and extracellular matrix (ECM surrounding them. Increasing evidence has suggested that accumulation of hyaluronan (HA, a major component of ECM, provides a favorable microenvironment for cancer progression. Pancreatic ductal adenocarcinoma (PDAC is characterized typically by a dense desmoplastic stroma with a large amount of HA, making this molecule as an attractive target for therapy. Several studies have shown efficacy of inhibitors of HA synthesis or signaling for the treatment of PDAC. Recent studies have also demonstrated substantial improvements in the effects of chemotherapy by a targeted depletion of stromal HA in PDAC using an enzymatic agent. Thus, targeting HA has been recognized as a promising therapeutic strategy to treat this highly aggressive neoplasm. In this review article, we summarize our current understanding of the role of HA in the progression of PDAC and discuss possible therapeutic approaches targeting HA.

  10. Role of the tumor microenvironment in pancreatic adenocarcinoma.

    2016-01-01

    Pancreatic cancer is a devastating disease with proclivity for early metastasis, which accounts for its poor prognosis. The clinical problem of pancreatic cancer is its resistance to conventional therapies, such as chemotherapy or radiation. Based upon these challenges, the focus of research on pancreatic cancer has shifted gradually towards the tumor microenvironment. The cancer microenvironment consists of various components, including fibroblasts, endothelial cells, immune cells, and endocrine cells, that interact with each other, and with the cancer cells in a complex fashion. Evidence is accumulating that the cancer microenvironment plays an active role in disease progression, and efforts are being made to target this interplay between cancer cells and host cells, to improve the prognosis of the disease. In the present review, we describe the cellular microenvironment of pancreatic ductal adenocarcinoma (PDA), the major type of pancreatic cancer. Our hope is that a better understanding of the cellular microenvironment of PDA will eventually lead to better treatments for this disease. PMID:26709759

    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 10B 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 10B 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.

  12. The microenvironment of liver metastases from Colorectal adenocarcinoma

    Eefsen, Rikke Løvendahl

    Colorectal adenocarcinoma (CRC) is the third most frequent cancer type worldwide and the third leading cause of cancer related death. During the course of the disease about 50% of patients are diagnosed with metastatic CRC (mCRC). The 5-year survival for patients who undergo a hepatic resection...... is about 40% and up to 58% in selected groups of patients, while the median overall survival for patients who receive palliative treatment has been reported to be from a few months and up to about 24 months, depending on dissemination of the cancer and response to treatment. The initial neo......-adjuvant treatment is crucial for patients with potential resectable liver metastases, allowing a subsequent hepatic resection if treatment have a downsizing effect on metastases.Antineoplastic agents include chemotherapy (e.g. 5-fluorouracil, oxaliplatin and irinotecan) or a combination of chemotherapy and targeted...

  13. Unusual Synchronous Lung Tumors: Mucoepidermoid Carcinoma and Mucinous Adenocarcinoma

    Ana M. Ponea

    2014-01-01

    Full Text Available Primary mucoepidermoid tumors of the lung are rare entities. Synchronous primary malignancies of the lung involving mucoepidermoid carcinoma and mucinous adenocarcinoma are even rarer and constitute a unique set of patient population. The presentation, diagnosis and treatment strategies for this patient population are not well described. In most cases, the diagnosis of synchronous primary lung malignancy is made after pathological examination of the resected lung specimen. Molecular and genetic analysis is now being used to supplement the diagnosis of synchronous primary lung malignancies. In this work, we briefly discuss the current state of knowledge of this unique combination of primary lung malignancies and describe the clinical presentation and management of a patient with a rare combination of synchronous primary lung malignancies.

  14. Resolution of lung adenocarcinoma after discontinuation of ibrutinib.

    Khashab, Tamer; Loghavi, Sanam; Konoplev, Sergej N; Samaniego, Felipe

    2016-01-01

    The new capability to generate mimicking chemical analogues and perform mass screenings of candidate drugs has been tested on B-cell receptor signalling, a driver of B-cell malignancies. These efforts have identified ibrutinib as a potent inhibitor of Bruton's tyrosine kinase. As the clinical use of ibrutinib increases, continued vigilant monitoring for rare adverse events is prudent, including the development of secondary malignancies. To date, the most common reported secondary malignancy is non-melanoma skin cancer; however, we present a case of secondary primary lung adenocarcinoma becoming clinically apparent shortly after initiating therapy with ibrutinib. Our patient had a sudden regression of the tumour with discontinuance of ibrutinib, and based on our understanding of paradoxical tumour growth caused by tyrosine kinase inhibitors it is our hypothesis that the complex multikinase activity of ibrutinib may stimulate tumour growth by targeting a subset of protein kinases critical for growth in some cancer cells.

  16. Osteoblastic flare effect during targeted therapy in lung adenocarcinoma

    Introduction: Incidence of osteoblastic bone flare effect during treatment of advanced lung cancer is rare. There were reported cases of this phenomenon after targeted therapy in metastatic non-small cell lung cancer. Case: The authors present a case of 55-year old patient with lung adenocarcinoma, where osteoblastic flare effect was observed after the first line treatment of chemotherapy plus bevacizumab. At progression of the disease genetic testing from biopsy of metastasis was performed and revealed EGFR mutation. Erlotinib was successfully introduced in the second line treatment, the second osteoblastic flare effect was observed. Conclusion: Knowledge of possible incidence of osteoblastic flare phenomenon during targeted therapy in advanced non-small cell lung cancer is important for correct evaluation of bone metastases development on scans and for proper decision not to stop this effective treatment prematurely.

    Adenocarcinoma is the most common type of lung cancer, the leading cause of cancer deaths in the world. Early detection is the key to improve the survival of lung adenocarcinoma patients. We have previously shown that microRNAs were stably present in sputum and could be applied to diagnosis of lung cancer. The aim of this study was to develop a panel of microRNAs that can be used as highly sensitive and specific sputum markers for early detection of lung adenocarcinoma. This study contained t...

  18. Clear cell adenocarcinoma of the ulterine cervix in a 15 year old girl: A case report

    Cervical cancer is rare in the pediatric population. In cases of cervical cancer, adenocarcinoma is predominantly reported. Clear cell adenocarcinoma (CCAC) of the uterine cervix is a very rare tumor and accounts for only 4% of all adenocarcinomas of the uterine cervix. Risk factors and pathogenesis of this disease are not exactly revealed. The intrauterine exposure to diethylstilbestrol (DES) and associated non-steroidal estrogen during pregnancy before 18 weeks is the only known risk factor. This study reports the imaging finding of primary uterine cervical tumor in a 15-year-old girl, who was finally diagnosed with CCAC, with no maternal history of DES exposure in utero.

  19. Salivary type alpha-amylase activity in serum and in urine of patients with lung adenocarcinoma

    Total alpha-amylase activity in sera and urine of 30 patients with lung adenocarcinoma has been tested. The results were compared with control group of 30 healthy voluntaries. The activity of pancreatic type was differentiated from salivary alpha amylase. Salivary type was inhibited selectively by Triticum aestivum. Higher levels of total and salivary type amylase were noted in patients with lung adenocarcinoma in comparison to healthy control. The increase was significant (p<0.005). Correlation was observed between the activity of salivary type amylase and the stage of adenocarcinoma. (author)

  20. Is cervical screening preventing adenocarcinoma and adenosquamous carcinoma of the cervix?

    Castanon, Alejandra; Landy, Rebecca; Sasieni, Peter D

    2016-09-01

    While the incidence of squamous carcinoma of the cervix has declined in countries with organised screening, adenocarcinoma has become more common. Cervical screening by cytology often fails to prevent adenocarcinoma. Using prospectively recorded cervical screening data in England and Wales, we conducted a population-based case-control study to examine whether cervical screening leads to early diagnosis and down-staging of adenocarcinoma. Conditional logistic regression modelling was carried out to provide odds ratios (ORs) and 95% confidence intervals (CIs) on 12,418 women with cervical cancer diagnosed between ages 30 and 69 and 24,453 age-matched controls. Of women with adenocarcinoma of the cervix, 44.3% were up to date with screening and 14.6% were non-attenders. The overall OR comparing women up to date with screening with non-attenders was 0.46 (95% CI: 0.39-0.55) for adenocarcinoma. The odds were significantly decreased (OR: 0.22, 95% CI: 0.15-0.33) in up to date women with Stage 2 or worse adenocarcinoma, but not for women with Stage1A adenocarcinoma 0.71 (95% CI: 0.46-1.09). The odds of Stage 1A adenocarcinoma was double among lapsed attenders (OR: 2.35, 95% CI: 1.52-3.62) compared to non-attenders. Relative to women with no negative cytology within 7 years of diagnosis, women with Stage1A adenocarcinoma were very unlikely to be detected within 3 years of a negative cytology test (OR: 0.08, 95% CI: 0.05-0.13); however, the odds doubled 3-5 years after a negative test (OR: 2.30, 95% CI: 1.67-3.18). ORs associated with up to date screening were smaller for squamous and adenosquamous cervical carcinoma. Although cytology screening is inefficient at preventing adenocarcinomas, invasive adenocarcinomas are detected earlier than they would be in the absence of screening, substantially preventing Stage 2 and worse adenocarcinomas.

    2015-01-01

    An 11 yr old castrated male greyhound presented to the Washington State University's Veterinary Teaching Hospital (WSU VTH) for evaluation of a 4 day history of pleural effusion. The pleural effusion had a gelatinous appearance, suggestive of mucus, and was characterized cytologically as a pyogranulomatous exudate with some features suggestive of a carcinoma. Postmortem examination identified a pulmonary mass with evidence of carcinomatosis. Pulmonary papillary adenocarcinoma with carcinomatosis was the histologic diagnosis. Abundant mucin production was present, consistent with a mucinous pulmonary adenocarcinoma. To the authors' knowledge, this is the first report of a mucinous pulmonary adenocarcinoma with mucus pleural effusion in a dog. PMID:26355581

  4. Gastric cardia adenocarcinoma in Taiwanese men: positive associations due to selection bias.

    Cervantes, Diana Treviño; Fischbach, Lori Ann

    2010-03-28

    The factors associated with an increase in gastric cardia adenocarcinoma are poorly understood. Environmental factors such as Helicobacter pylori (H. pylori) infection and diet have been hypothesized to play a role in the recently increased risk of this disease, but additional studies are needed. In conducting studies to establish the relationship between potential risk factors and gastric cardia adenocarcinoma, it is necessary to carefully consider the role of bias. In a recently published study, the reported associations between H. pylori as well as post-meal physical exertion and gastric cardia adenocarcinoma may have been greatly influenced by selection bias.

  5. Atypical adenocarcinoma of the colon : radiologic-pathologic correlation

    To analyse unusual radiologic manifestations of colonic adenocarcinoma, and to correlate these with pathologic findings. Radiologic findings of ten patients with atypical adenocarcinoma of the colon were retrospectively evaluated. The unusual radiologic findings were defined as terminal ileal involvement of the cecal mass, long segmental involvement of oner 9cm, and exophytic tumor growth. Radiologic and sonographic findings were compared with pathologic specimens obtained from surgical resection. Involvement of the terminal ileum was noted in three cases, long segmental involvement of 11 cm in five cases, and exophytic mass in two. of three cases with thickening of the terminal ileum, two revealed the infiltration of cancer into the terminal ileum through the ileocecal valve, and the other revealed vascular congesion and edema on microscopic examination. Five cases with long segmental involvement of over 11 cm comprised on e of cancer totally infiltrated through the submucosal and proper muscle layer, one of inflammatory thickening distal to the cancer, two of inflammatory change of pericolic fat and serosal adhesion and one of a large intraluminal fungating mass. In the cases of exophytic mass, one with a larger extraluminal and a smaller intraluminal component revealed necrosis and abscess on pathologic examination, accounting for low attenuation on CT, whereas the other, with exophytic growth, disclosed abundant pools of mucin, resulting in low attenuation on CT. These two cases could not be differentiated from submucosal tumors. Atypical colon cancer may have various manifestations, such as thickening of the terminal ileum, involvement of a long segment, and an exophytically growing mass. An appreciation of the radiologic findings of this cancer may therefore help in differential diagnosis in cases simulating colitis or submucosal tumors of the colon, such as lymphoma or leiomyoma

    2002-01-01

    Full Text Available There exists a rarely observed association between pulmonary histiocytosis X and bronchopulmonary cancer. However, the frequency of bronchopulmonary cancer in these patients is higher than in the general population. A 28-year-old patient who currently smokes ten packs of cigarettes a year came to our department of pneumology with complains of cough and hemoptysis. An x-ray of the thorax revealed bilateral cysts and a shadow in the upper part of the right pulmonary field. In addition, a chest tomography showed multiple cysts dispersed throughout the two pulmonary fields and an irregular mass with a diameter of four centimetres in the upper right lobe. Bronchopulmonary adenocarcinoma was diagnosed during a cytologic exam of the bronchial washing. We decided to perform a thoracotomy on the patient, since there was no far metastasis. An upper lobectomy and wedge resection of the upper segment of the lower right lobe, which had been invaded by the tumour, were performed. Histology confirmed the diagnosis of adenocarcinoma. A pulmonary biopsy was carried out on the tumour-free site and showed the presence of histiocytosis X. There is a hypothesis that a neoplasm developed on the pulmonary fibrosis could be an epiphenomenon of bronchopulmonary cancer in patients who smoke and have pulmonary histiocytosis X. It is interesting to note that histiocytosis X and bronchopulmonary cancer were diagnosed at the same time, since the bronchopulmonary cancer may have occurred within a few years following the diagnosis of histiocytosis X, even if she was a smoker. Hemoptysis, which is found in 5% of patients with histiocytosis X, may suggest cancer. This young patient, a smoker, who complained of hemoptysis, is a particularly rare case of the association between pulmonary histiocytosis X and bronchopulmonary cancer whose pathogenesis is not clear cut. It is thus important to note that smoking can have major consequences, even in young people.

  7. Cryptosporidium parvum, a potential cause of colic adenocarcinoma

    Pinon Anthony

    2007-11-01

    Full Text Available Abstract Background Cryptosporidiosis represents a major public health problem. This infection has been reported worldwide as a frequent cause of diarrhoea. Particularly, it remains a clinically significant opportunistic infection among immunocompromised patients, causing potentially life-threatening diarrhoea in HIV-infected persons. However, the understanding about different aspects of this infection such as invasion, transmission and pathogenesis is problematic. Additionally, it has been difficult to find suitable animal models for propagation of this parasite. Efforts are needed to develop reproducible animal models allowing both the routine passage of different species and approaching unclear aspects of Cryptosporidium infection, especially in the pathophysiology field. Results We developed a model using adult severe combined immunodeficiency (SCID mice inoculated with Cryptosporidium parvum or Cryptosporidium muris while treated or not with Dexamethasone (Dex in order to investigate divergences in prepatent period, oocyst shedding or clinical and histopathological manifestations. C. muris-infected mice showed high levels of oocysts excretion, whatever the chemical immunosuppression status. Pre-patent periods were 11 days and 9.7 days in average in Dex treated and untreated mice, respectively. Parasite infection was restricted to the stomach, and had a clear preferential colonization for fundic area in both groups. Among C. parvum-infected mice, Dex-treated SCID mice became chronic shedders with a prepatent period of 6.2 days in average. C. parvum-inoculated mice treated with Dex developed glandular cystic polyps with areas of intraepithelial neoplasia, and also with the presence of intramucosal adenocarcinoma. Conclusion For the first time C. parvum is associated with the formation of polyps and adenocarcinoma lesions in the gut of Dex-treated SCID mice. Additionally, we have developed a model to compare chronic muris and parvum

    Gregorio Rodríguez Boto

    2011-10-01

    Full Text Available Los neurinomas del plexo braquial son tumores infrecuentes que pueden confundirse con otras lesiones de índole tumoral. Se presenta el caso de una mujer de 40 años, tratada previamente de un adenocarcinoma de mama derecha en el pasado, que en el estudio de extensión realizado 5 años después se detectó una lesión localizada en el plexo braquial derecho. La paciente se encontraba asintomática. El diagnóstico radiológico de presunción fue metástasis de adenocarcinoma mamario. Se realizó un abordaje axilar derecho descubriendo una lesión bien delimitada en el plexo braquial. Con ayuda de la monitorización neurofisiológica intraoperatoria, se observó que la lesión dependía de la rama cubital y se pudo realizar una resección completa preservando la función de dicho nervio. El estudio anatomopatológico confirmó que se trataba de un neurinoma, descartando así la existencia de metástasis. La evolución postoperatoria fue satisfactoria. Seis años después de la intervención no existe recidiva tumoral. En nuestro conocimiento este es el primer caso publicado en la literatura de un neurinoma del plexo braquial dependiente de la rama cubital. La monitorización neurofisiológica intraoperatoria resulta fundamental para abordar este tipo de lesiones con baja morbilidad.

  9. Mucinous adenocarcinoma ovary: diagnostic dilemma and the usefulness of colonoscopy

    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.

    2015-06-01

    Full Text Available Background Worldwide, gastric cancer is the fourth cancer in incidence and the second most common cause of cancer death. Gastric cancer is asymptomatic in the early stages and very often diagnosed at advanced stages, determining a dismal prognosis. Expression of the HER2 gene has been identified in about 20% of gastric cancer cases, and its hyper-expression is associated with poor prognosis. Objective To investigate HER2 immunohistochemical expression in gastric adenocarcinoma and its relationship to the histological type and anatomic location. Methods A cross-sectional retrospective study analyzed the immunohistochemical expression of HER2 in a sample of 48 specimens of gastric cancer. Immunohistochemical analysis were performed using avidin-biotin-peroxidase method with C-erb B2 (clone EP1045Y, as a primary antibody (Biocare Medical, USA. Standardized gastric adenocarcinoma‘s HER2 expression criteria has been used in the analysis of samples. Results There were seven cases with reactivity for HER2. Five were of intestinal-type while two cases were of mixed-type in which the expression occurred in the intestinal component. It was identified a significant association of HER2 expression in the intestinal subtype of gastric adenocarcinoma (P=0.003. Regarding the anatomical site, HER2 was positive in only one (16.6% of the six proximal cases and six (14.28% of the 42 distal cases (P=0.88. Conclusion HER2 immunoexpression was identified in 14.6% of the samples, and the expression was significantly associated to Lauren’s intestinal subtype.

  11. Sulphamoylated 2-methoxyestradiol analogues induce apoptosis in adenocarcinoma cell lines.

    Michelle Visagie

    Full Text Available 2-Methoxyestradiol (2ME2 is a naturally occurring estradiol metabolite which possesses antiproliferative, antiangiogenic and antitumor properties. However, due to its limited biological accessibility, synthetic analogues have been synthesized and tested in attempt to develop drugs with improved oral bioavailability and efficacy. The aim of this study was to evaluate the antiproliferative effects of three novel in silico-designed sulphamoylated 2ME2 analogues on the HeLa cervical adenocarcinoma cell line and estrogen receptor-negative breast adenocarcinoma MDA-MB-231 cells. A dose-dependent study (0.1-25 μM was conducted with an exposure time of 24 hours. Results obtained from crystal violet staining indicated that 0.5 μM of all 3 compounds reduced the number of cells to 50%. Lactate dehydrogenase assay was used to assess cytotoxicity, while the mitotracker mitochondrial assay and caspase-6 and -8 activity assays were used to investigate the possible occurrence of apoptosis. Tubulin polymerization assays were conducted to evaluate the influence of these sulphamoylated 2ME2 analogues on tubulin dynamics. Double immunofluorescence microscopy using labeled antibodies specific to tyrosinate and detyrosinated tubulin was conducted to assess the effect of the 2ME2 analogues on tubulin dynamics. An insignificant increase in the level of lactate dehydrogenase release was observed in the compounds-treated cells. These sulphamoylated compounds caused a reduction in mitochondrial membrane potential, cytochrome c release and caspase 3 activation indicating apoptosis induction by means of the intrinsic pathway in HeLa and MDA-MB-231 cells. Microtubule depolymerization was observed after exposure to these three sulphamoylated analogues.

    Adenocarcinomas exhibiting gastric differentiation represent a recently described and uncommon subtype of non-human papillomavirus (HPV)-related cervical adenocarcinoma. They comprise a spectrum from a well-differentiated variant (adenoma malignum/mucinous variant of minimal deviation adenocarcinoma) to a more poorly differentiated overtly malignant form, generally referred to as gastric-type adenocarcinoma. Rarely, such tumors have also been described as primary vaginal neoplasms. Gastric-type adenocarcinomas exhibit considerable morphologic overlap with adenocarcinomas originating outside the female genital tract, especially mucinous adenocarcinomas arising in the pancreas and biliary tract. Moreover, they often metastasize to unusual sites, such as the ovary and peritoneum/omentum, where they can be mistaken for metastatic adenocarcinomas from other, nongynecologic sites. There is little information regarding the immunophenotype of gastric-type adenocarcinomas, and knowledge of this is important to aid in the distinction from other adenocarcinomas. In this study, we undertook a detailed immunohistochemical analysis of a large series of cervical (n=45) and vaginal (n=2) gastric-type adenocarcinomas. Markers included were cytokeratin (CK)7, CK20, CDX2, carcinoembryonic antigen, CA125, CA19.9, p16, estrogen receptor, progesterone receptor, MUC6, PAX8, PAX2, p53, hepatocyte nuclear factor 1 beta, carbonic anhydrase IX, human epidermal receptor 2 (HER2), and mismatch repair (MMR) proteins. All markers were classified as negative, focal (<50% of tumor cells positive), or diffuse (≥50% tumor cells positive) except for p53 (classified as "wild-type" or "mutation-type"), HER2 (scored using the College of American Pathologists guidelines for gastric carcinomas), and MMR proteins (categorized as retained or lost). There was positive staining with CK7 (47/47-45 diffuse, 2 focal), MUC6 (17/21-6 diffuse, 11 focal), carcinoembryonic antigen (25/31-12 diffuse, 13 focal

    2014-01-01

    Cisplatin/pemetrexed chemotherapy has been established as a standard treatment in lung adenocarcinoma. However, the response to the cisplatin/pemetrexed combination varies considerably among patients due to individual variations. Thus, novel biomarkers are required to aid the prediction of the response to the cisplatin/pemetrexed combination. We hypothesized that leptin expression may be a determinant for prognosis in lung adenocarcinoma patients with cisplatin/pemetrexed chemotherapy. Serum ...

  13. Battling Barrett's esophagus: uncovering the genetics and epigenetics of Barrrett's esophagus and esophageal adenocarcinoma

    Streppel, M.M.

    2014-01-01

    Barrett’s esophagus (BE) is a common premalignant condition of the distal esophagus with a high incidence among Caucasian males. It is an important risk factor for the development of esophageal adenocarcinoma (EAC). EACs arise in BE following a multistep sequence through low- and high-grade dysplasia, finally culminating in an invasive adenocarcinoma. Because of this increased risk of developing an EAC and poor prognosis of EAC patients, BE patients are offered endoscopic surveillance in orde...

    2016-04-01

    Secondary metastatic tumours of the uterine cervix are rare. There have been no reports of duodenal cancer metastasizing to the uterine cervix. Here we present a rare case of an extra-ampullary duodenal adenocarcinoma that has metastasized to the uterine cervix. The patient was a 71-year-old woman who had surgery for an extra-ampullary duodenal adenocarcinoma five years previously. Follow-up examination revealed a suspicious right ovarian mass and nodules in the cervix and posterior fornix of the vagina. Biopsies suggested squamous cell carcinoma in the cervix and adenocarcinoma in the fornix. Intraoperatively, the right ovary was enlarged and peritoneal disseminations were found in the pouch of Douglas and the sigmoid colon mesentery. Histopathology of the subsequent hysterectomy and bilateral salpingo-oophorectomy specimen revealed a cervical squamous cell carcinoma categorized as pT1b1. Adenocarcinoma infiltration into the ovaries, uterine cervix and vagina, with vascular involvement was detected. Immunohistochemistry revealed the tumour in the cervix and ovaries to be positive for CK7, MUC5AC and MUC6, and immunonegative for CK20, CDX2, Pax8, ER, MUC2 and CD10, similar to the original duodenal adenocarcinoma. This case illustrates the difficulty in making a preoperative diagnosis of metastatic adenocarcinoma in the uterine cervix with a coexisting primary cervical squamous cell carcinoma. The absence of atypia in cervical glandular cells and immunohistochemical profiling of the adenocarcinoma clusters helped to reach a final diagnosis. This is the first report of an extra-ampullary duodenal adenocarcinoma metastasis to the uterine cervix. PMID:27126664

    2013-11-01

    Background: The prognostic value of maximum standardized uptake value (maxSUV) on {sup 18}F-fluorodeoxyglucose positron emission tomography (FDG-PET) is known for localized pulmonary adenocarcinoma, which is most commonly non-mucinous adenocarcinoma. We examined the validity of thin-section computed tomography (TS-CT) and FDG-PET findings in mucinous adenocarcinoma. Materials and Methods: TS-CT and FDG-PET were performed on 25 patients with mucinous lung adenocarcinoma that was subsequently resected between January 2009 and March 2013. Based on the percentage reduction of maximum tumor diameter on the mediastinal window image compared with the diameter on the lung window image on TS-CT, tumors were classified as air-type (≥50%) or solid-type (<50%). All resected specimens were pathologically diagnosed according to the International Association for the Study of Lung Cancer (IASLC) classification, and the diameter of the pathological invasive area was assessed. Results: Most mucinous adenocarcinomas were located in the lower lobe. All except two were classified as solid-type tumor on TS-CT. Multiple regression analysis revealed the correlation of maxSUV with pathological tumor size and diameter of pathological invasive area; these two parameters showed no significant correlation with each other (r = 0.354, p = 0.083). maxSUV was significantly lower for tumors with invasive area ≤5 mm than for tumors with invasive area >5 mm (1.62 vs. 3.77, p = 0.01), but no statistically significant difference was found in terms of other pathological invasive findings such as the presence of lymphatic or vascular invasion, pleural involvement, or predominant histological subtype. Conclusions: Most mucinous adenocarcinomas had appearances of solid-type tumor on TS-CT. maxSUV on FDG-PET indicates the pathological invasive area in mucinous adenocarcinoma as well as non-mucinous adenocarcinoma.

  18. Gastric-Type Extremely Well-Differentiated Adenocarcinoma of the Stomach: A Challenge for Preoperative Diagnosis

    Joo, Mee; Han, Song Hee

    2015-01-01

    Gastric-type extremely well-differentiated adenocarcinoma (EWDA) is a rare type of gastric adenocarcinoma characterized by infiltration of well-formed mucinous glands with little or no nuclear atypia, which resemble foveolar epithelium or pyloric glands. Because of its high degree of differentiation, preoperative biopsy diagnosis of gastric-type EWDA is very difficult. We encountered a case of gastric-type EWDA, manifesting as a Borrmann type 4 lesion, in a 47-year-old man. Despite four repea...

    Kerr, Keith M.; Galler, Janice S; Hagen, Jeffrey A.; Laird, Peter W; Laird-Offringa, Ite A.

    2007-01-01

    Lung cancer, caused by smoking in ∼87% of cases, is the leading cause of cancer death in the United States and Western Europe. Adenocarcinoma is now the most common type of lung cancer in men and women in the United States, and the histological subtype most frequently seen in never-smokers and former smokers. The increasing frequency of adenocarcinoma, which occurs more peripherally in the lung, is thought to be at least partially related to modifications in cigarette manufacturing that have ...

  14. IMP3 can predict aggressive behaviour of lung adenocarcinoma

    2012-01-01

    Background Lung cancer most often presents as an inoperable tumour and the diagnosis is usually performed on a small biopsy/cytology specimen. In the group of non small cell lung cancer - not otherwise specified, adenocarcinoma phenotype can be determined immunohistochemically using TTF-1 and Napsin A. Expression of oncofetal protein IMP3 in human cancer is associated with poor differentiation and aggressive behaviour. In the present study expression of IMP3 was correlated with expression of TTF-1 and Napsin A, histological subtype and clinical stage of lung adenocarcinoma. We were interested whether distant metastases are associated with IMP3 overexpression, regardless of the histologic subtype of adenocarcinoma. Methods In retrospective study, consecutive series of 105 patients with advanced lung adenocarcinoma diagnosed from 2006 to 2009 in Clinical Hospital Center Split, Croatia, were analysed. Clinical data were collected from the Pulmology Department and time of death from the Mortality Registry. Paraffin blocks of bronchoscopic biopsies were collected from the Institute of Pathology and 15 cases excluded from the analysis due to insufficient material. Expression of IMP3, Napsin A and TTF-1 were analysed by indirect enzyme immunohistochemistry. Statistical analysis was performed and P values less than 0.05 considered significant. Results Of 90 patients, 71 (78%) were males and 19 (22%) females. Median age for males was 61.5 years (min-max 43–83) and for females 61 years (min-max 44–86). Pleural effusion was found in 15 (16.6%) and distant metastases in 45 (50%) cases. According to histological subtypes, there were 34 acinar, 2 lepidic, 2 papillary and 52 solid subtypes. IMP3 overexpression was found in 63 cases (70%) and was correlated with solid subtype (P = 0.002) and negative/weak Napsin A expression (P = 0.004). Strong Napsin A expression correlated with TTF-1 expression (P = 0.003) and lower histological grades (P = 0.031). Patients

  16. Identification of risk factors of prostate adenocarcinoma recurrence after HIFU therapy using immunohistochemical markers

    Popkov V.M.

    2014-12-01

    Full Text Available The purpose of this study was to identify risk factors for recurrence of prostate adenocarcinoma after HIFU therapy. Material and methods: Material for the study was obtained from patients diagnosed with adenocarcinoma before and after HIFU treatment. Morphological study was conducted using a standard staining, and immunohistochemical markers: PCNA, Amacr, E-cadherin, Bel2, Andr, Estr, VEGF, P53, PCNA. Results: After treatment in 89% of patients with initial prostate volume greater than 50 cc the signs of recurrence of adenocarcinoma were showed. At low risk for D'Amico after treatment the expression of proliferation markers, VEGF, Amacr significantly decreased. With a high degree of risk — increased expression of Bel2. After treatment the expression of the following markers: PCNA, Amacr, VEGF significantly increased in the group of patients with the presence of invasion. Conclusion: Patients with initial prostate volume less than 50 cc, low risk to D'Amico, the lack of perineural and perivascular invasion have a low risk of recurrence after HIFU therapy; patients at high risk for D'Amico, the presence of perineural and perivascular invasion initial and prostate volume greater than 50 cc, low-grade cribriform form of adenocarcinoma have a high risk of recurrence of adenocarcinoma. Recurrence of adenocarcinoma develops independently of the period after HIFU therapy.

  17. The comparison of CT findings between peripheral pulmonary squamous cell carcinoma and pulmonary adenocarcinoma

    Objective: To compare the principal HRCT features of peripheral pulmonary squamous cell carcinoma and pulmonary adenocarcinoma and to explore their pathological mechanism, in order to improve the recognition of the CT signs of peripheral pulmonary carcinoma. Methods: The principal HRCT signs of thirty-five cases with pathologically proved peripheral pulmonary squamous cell carcinoma and forty cases with pathologically proved peripheral pulmonary adenocarcinoma were analyzed retrospectively to explore the relationship between CT features and pathological findings. Results: The main features of peripheral pulmonary squamous cell carcinoma included larger masses, clear boundary, superficial sublobes and intra-tumor necrosis. While peripheral pulmonary adenocarcinoma mostly demonstrated as smaller nodules, deep sublobes, spiculations, spiculate protuberance, pleural indentation, vessel converging signs, and vacuole signs. The different of these above findings of peripheral pulmonary squamous cell carcinoma and adenocarcinoma were significant (P<0.05). Peripheral pulmonary squamous cell carcinoma may depict bronchial casts and polygonal nodules; and peripheral pulmonary adenocarcinoma may demonstrate ground glass-like nodules. Conclusion: The difference of the CT findings between peripheral pulmonary squamous cell carcinoma and peripheral adenocarcinoma is based on their different histological features and biological behaviors. It is possible to differentiate them before operation in combination with clinical information. (authors)

    2005-01-01

    AIM: To investigate the expression of leptin and leptin receptor (ob-R) in intestinal-type gastric cancer and precancerous lesions, and to explore the possible mechanism and role of the leptin system in developing intestinal-type gastric adenocarcinoma.METHODS: Immunohistochemistry was performed to examine the expression of leptin and leptin receptor in archival samples of gastric adenocarcinoma and preneoplastic lesions, including intestinal metaplasia and mild to severe gastric epithelial dysplasia. Positive staining was identified and percentage of positive staining was graded.RESULTS: Dual expression of leptin and leptin receptor were detected in 80% (16/20) intestinal metaplasia,86.3% (25/30) mild gastric epithelial dysplasia, 86.7%(26/30) moderate gastric epithelial dysplasia, 93.3%(28/30) severe gastric epithelial dysplasia, 91.3% (55/60)intestinal-type gastric adenocarcinoma and 30.0% (9/30)difffuse-type gastric carcinoma. The percentage of dual expression of leptin and leptin receptor in intestinal-type gastric adenocarcinoma was significantly higher than that in diffuse-type gastric adenocarcinoma (x2 = 37.022,P<0.01).CONCLUSION: Our results indicate the presence of an autocrine loop of leptin system in the development of intestinal-type gastric adenocarcinoma.

  19. Mesotheliomas show higher hyaluronan positivity around tumor cells than metastatic pulmonary adenocarcinomas.

    Törrönen, Kari; Soini, Ylermi; Pääkkö, Paavo; Parkkinen, Jyrki; Sironen, Reijo; Rilla, Kirsi

    2016-10-01

    Hyaluronan is a unique glycosaminoglycan of the extracellular matrix, abundant in normal connective tissues but highly increased in many pathological conditions like cancer. Mesothelioma, one of the most malignant cancer types, is associated with high content of hyaluronan, with elevated levels of hyaluronan in pleural effusions and serum of the patients. Metastatic lung adenocarcinomas are typically less aggressive and have a better prognosis as compared to mesotheliomas, a reason why it is highly important to find reliable tools to differentiate these cancer types. The main purpose of this study was to evaluate the amount of hyaluronan, hyaluronan producing synthases (HAS's) and hyaluronan receptor CD44, in mesothelioma and metastatic lung adenocarcinomas. Furthermore, we wanted to clarify the role of hyaluronan, CD44 and HAS's as putative markers for differentiating malignant mesothelioma from metastatic lung adenocarcinomas. The main finding of this study was that mesotheliomas are significantly more positive for hyaluronan staining than metastatic adenocarcinomas. Unexceptionally, a trend of CD44 positivity of stromal cells was higher in adenocarcinomas as compared to mesotheliomas. However, no statistically significant differences were found between the staining of any of the HAS isoenzymes either in tumor cells or stromal cells of different groups of cases. The results show that there are significant differences in hyaluronan content between metastatic lung adenocarcinomas and mesotheliomas. However, as previous studies have suggested, hyaluronan alone is not a sufficient independent marker for diagnostic differentiation of these cancer types, but could be utilized as a combination together with other specific markers.

    AIM: To investigate risk factors associated with Barrett's oesophagus and oesophageal adenocarcinoma.METHODS: This all-Ireland population-based case-control study recruited 224 Barrett's oesophagus patients, 227 oesophageal adenocarcinoma patients and 260 controls. All participants underwent a structured interview with information obtained about potential lifestyle and environmental risk factors.RESULTS: Gastro-oesophageal reflux was associated with Barrett's [OR 12.0 (95% CI 7.64-18.7)] and oesophageal adenocarcinoma [OR 3.48 (95% CI 2.25-5.41)]. Oesophageal adenocarcinoma patients were more likely than controls to be ex- or current smokers [OR 1.72 (95% CI 1.06-2.81) and OR 4.84 (95% CI 2.72-8.61) respectively] and to have a high body mass index [OR 2.69 (95% CI 1.62-4.46)]. No significant associations were observed between these risk factors and Barrett's oesophagus. Fruit but not vegetables were negatively associated with oesophageal adenocarcinoma [OR 0.50 (95% CI 0.30-0.86)].CONCLUSION: A high body mass index, a diet low in fruit and cigarette smoking may be involved in the progression from Barrett's oesophagus to oesophageal adenocarcinoma.

    Full Text Available Background and objective Patients with adenocarcinoma of the lung have disproportionately response to the epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI. The aim of this study is to analyze the difference of EGFR gene amplification in bronchioloalveolar carcinoma (BAC, adenocarcinma mixed subtype and conventional adenocarcinoma of the lung and provide some information to clinical therapies. Methods Lung cancer cases were collected and reviewed from the archives of the Department of Pathology, Chinese PLA General Hospital during the time period from 2004 to 2006. The definite diagnosis of BAC based on 2004 WHO classification of lung tumors was made by two pathologists. Fluorescence in situ hybridization (FISH was performed to detect EGFR gene amplification in pure BAC, adenocarcinma mixed subtype and conventional adenocarcinoma. Results Conventional adenocarcinoma had higher EGFR amplification compared with pure BAC and adenocarcinma mixed subtype (χ2=11.632, P<0.05. EGFR gene amplification was found in 45.45% of conventional adenocarcinoma, 14.81% in pure BACs, and 22.58% in adenocarcinma mixed subtype. EGFR gene amplification was observed as scattered signals in most cases. Conclusion EGFR gene amplification was seen more frequently in the invasive components than in BAC. EGFR gene amplification might be associated with the development of adenocarcinoma of the lung.

  2. Dynamic MR imaging: value of differentiating subtypes of peripheral small adenocarcinoma of the lung

    Purpose: To determine the utility of dynamic magnetic resonance imaging (MRI) in the differential subtyping of small adenocarcinomas of the lung. Materials and methods: Twenty-nine pathologically diagnosed peripheral adenocarcinomas (less than 20 mm in diameter) underwent dynamic contrast-enhanced MRI. Maximum relative enhancement ratio, slope of enhancement, and corrected start time of enhancement were calculated from signal intensity-time curve of pulmonary lesion for each subject, and were statistically compared among bronchioloalveolar carcinoma (BAC) group (7 cases), mixed BAC group (10 cases), and adenocarcinoma group (12 cases). Results: Maximum relative enhancement ratio (P<0.001) and slope of enhancement (P<0.001) of BAC group were significantly higher than those of mixed BAC and adenocarcinoma groups. Start times of BAC group were significantly earlier than those of mixed BAC (P=0.0001) and adenocarcinoma groups (P<0.0001). Adapting the thresholds values of MR indexes from the positive tests, sensitivity, specificity, positive predictive value, negative predictive value and accuracy for differentiating BAC from other subtypes were 85.7, 100.0, 100.0, 95.7, and 96.6%, respectively. Conclusions: Dynamic MRI is useful for differentiating subtypes of small peripheral adenocarcinoma

    Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract, and gastric adenocarcinomas are a common cancer worldwide. To differentiate GISTs from adenocarcinomas is important because the surgical processes for both are different; the former excises the tumor with negative margins, while the latter requires radical gastrectomy with lymph node dissection. Endoscopy with biopsy is used to distinguish GISTs from adenocarcinomas; however, it may cause tumor bleeding in GISTs. We reported here the confocal Raman microspectroscopy as an effective tool to differentiate GISTs, adenocarcinomas, and normal mucosae. Of 119 patients enrolled in this study, 102 patients underwent gastrectomy (40 GISTs and 62 adenocarcinomas), and 17 patients with benign lesions were obtained as normal mucosae. Raman signals were integrated for 100 s for each spot on the specimen, and 5 to 10 spots, depending on the sample size, were chosen for each specimen. There were significant differences among those tissues as evidenced by different Raman signal responding to phospholipids and protein structures. The spectral data were further processed and analyzed by using principal component analysis. A two-dimensional plot demonstrated that GISTs, adenocarcinomas, and normal gastric mucosae could be effectively differentiated from each other.

    For intraoperative consultation of mucinous adenocarcinoma involving the ovary, it would be useful to have approaching methods in addition to the traditional limited microscopic findings in order to determine the nature of the tumors. Mucinous adenocarcinomas involving the ovaries were evaluated in 91 cases of metastatic mucinous adenocarcinomas and 19 cases of primary mucinous adenocarcinomas using both an original algorithm (unilateral ≥10 cm tumors were considered primary and unilateral <10 cm tumors or bilateral tumors were considered metastatic) and a modified cut-off size algorithm. With 10 cm, 13 cm, and 15 cm size cut-offs, the algorithm correctly classified primary and metastatic tumors in 82.7%, 87.3%, and 89.1% of cases and in 80.6%, 84.9%, and 87.1% of signet ring cell carcinoma (SRC) excluded cases. In total cases and SRC excluded cases, 98.0% and 97.2% of bilateral tumors were metastatic and 100% and 100% of unilateral tumors <10 cm were metastatic, respectively. In total cases and SRC excluded cases, 68.4% and 68.4% of unilateral tumors ≥15 cm were primary, respectively. The diagnostic algorithm using size and laterality, in addition to clinical history, preoperative image findings, and operative findings, is a useful adjunct tool for differentiation of metastatic mucinous adenocarcinomas from primary mucinous adenocarcinomas of the ovary.

However, little is known regarding the prognostic value of SIRT1 in lung adenocarcinoma. Therefore, the aim of this study is to evaluate the role of SIRT1 in the prognosis of lung adenocarcinoma patients. Using a tissue microarray, we detected SIRT1 expression by immunohistochemistry in lung adenocarcinoma tissue, as well as in corresponding noncancerous tissues (NCTs. A high expression level of SIRT1 was observed in 74.7% (56/75 of patients with lung adenocarcinoma and 6.7% (5/75 of NCTs (P<0.001. SIRT1 expression was significantly associated with high pathological stage. Importantly, we found that SIRT1 expression was associated with worse overall survival in these lung adenocarcinoma patients (67.0 months vs 104.5 months; P=0.005. In addition, anaplastic lymphoma kinase, epidermal growth factor receptor, vascular endothelial growth factor (VEGF, and Survivin expression were evaluated by fluorescent in situ hybridization or immunohistochemistry, respectively. We found that VEGF and Survivin were both highly expressed in the lung adenocarcinoma tissues, as compared to NCTs. Moreover, the SIRT1 and VEGF expression statuses were significantly positively correlated (r=0.238, P=0.039, while SIRT1 and Survivin expression status were not

    Adenocarcinomas are the most common cause of malignancy in pleura fluids. Usual primary sites include the lung, breast, gastrointestinal tract, and genitourinary tracts. Predicting the site of origin of an adenocarcinoma can be difficult due to overlapping morphologic characteristics. We investigated the use of alkaline phosphatase (AP), Cytokeratin7 (CK7) Cytokeratin8 (CK8) to distinguish adenocarcinomas of lung in 148 body cavity fluid samples.

  9. Ad-IRF-1 Induces Apoptosis in Esophageal Adenocarcinoma

    Gregory A. Watson

    2006-01-01

    Full Text Available The nuclear transcription factor interferon regulatory factor-1 (IRF-1 is a putative tumor suppressor, but the expression and function of IRF-1 in esophageal adenocarcinoma (EA remain unknown. We hypothesized that IRF-1 expression was reduced or lost in EA and that restoration of IRF-1 would result in the apoptosis of EA cells in vitro and the inhibition of tumor growth in vivo. Three EA cell lines were used to examine IRF-1 expression, IFN-γ responsiveness, and the effects of IRF-1 overexpression using a recombinant adenoviral vector (Ad-IRF-1. All three EA cell lines produced IRF-1 protein following IFN-γ stimulation, although IFN-γ did not induce cell death. In contrast, Ad-IRF-1 infection resulted in high levels of IRF-1 protein and triggered apoptosis in all three EA cell lines. Potential mechanisms for the differential response to IFN-γ versus Ad-IRF-1-such as modulation of c-Met or extracellular regulated kinase signaling, or altered expression of IRF-2, Fas, or survivin-were investigated, but none of these mechanisms can account for this observation. In vivo administration of IRF-1 in a murine model of EA modestly inhibited tumor growth, but did not lead to tumor regression. Strategies aimed at increasing or restoring IRF-1 expression may have therapeutic benefits in EA.

    The molecular chaperone HSP90 is involved in stabilization and function of multiple client proteins, many of which represent important oncogenic drivers in NSCLC. Utilization of HSP90 inhibitors as radiosensitizing agents is a promising approach. The antitumor activity of ganetespib, HSP90 inhibitor, was evaluated in human lung adenocarcinoma (AC) cells for its ability to potentiate the effects of IR treatment in both in vitro and in vivo. The cytotoxic effects of ganetespib included; G2/M cell cycle arrest, inhibition of DNA repair, apoptosis induction, and promotion of senescence. All of these antitumor effects were both concentration- and time-dependent. Both pretreatment and post-radiation treatment with ganetespib at low nanomolar concentrations induced radiosensitization in lung AC cells in vitro. Ganetespib may impart radiosensitization through multiple mechanisms: such as down regulation of the PI3K/Akt pathway; diminished DNA repair capacity and promotion of cellular senescence. In vivo, ganetespib reduced growth of T2821 tumor xenografts in mice and sensitized tumors to IR. Tumor irradiation led to dramatic upregulation of β-catenin expression in tumor tissues, an effect that was mitigated in T2821 xenografts when ganetespib was combined with IR treatments. These data highlight the promise of combining ganetespib with IR therapies in the treatment of AC lung tumors.

    Barrett’s esophagus, is thought to progress to esophageal adenocarcinoma (EAC) through a step-wise progression with loss of CDKN2A followed by p53 inactivation and aneuploidy. Here, we present whole exome sequencing from 25 pairs of EAC and Barrett’s and five patients whose Barrett’s and tumor were extensively sampled. Our analysis revealed that oncogene amplification typically occurred as a late event and that TP53 mutations often occur early in Barrett’s progression, including in non-dysplastic epithelium. Reanalysis of additional EAC exome data revealed that the majority (62.5%) of EACs emerged following genome doubling and that tumors with genomic doubling had different patterns of genomic alterations with more frequent oncogenic amplifications and less frequent inactivation of tumor suppressors, including CDKN2A. These data suggest that many EACs emerge not through gradual accumulation of tumor suppressor alterations but rather through a more direct path whereby a TP53-mutant cell undergoes genome doubling, followed by acquisition of oncogenic amplifications.

  12. Human pancreatic adenocarcinoma contains a side population resistant to gemcitabine

    Therapy resistance remains one of the major challenges to improve the prognosis of patients with pancreatic cancer. Chemoresistant cells, which potentially also display cancer stem cell (CSC) characteristics, can be isolated using the side population (SP) technique. Our aim was to search for a SP in human pancreatic ductal adenocarcinoma (PDAC) and to examine its chemoresistance and CSC(−like) phenotype. Human PDAC samples were expanded in immunodeficient mice and first-generation xenografts analyzed for the presence of a Hoechst dye-effluxing SP using flow cytometry (FACS). To investigate chemoresistance of the SP, mice bearing PDAC xenografts were treated with gemcitabine and SP proportion determined. In addition, the SP and the main tumour cell population (MP) were sorted by FACS for RNA extraction to profile gene expression, and for culturing under sphere-forming conditions. A SP was identified in all PDAC samples, analyzed. This SP was more resistant to gemcitabine than the other tumour cells as examined in vivo. Whole-genome expression profiling of the SP revealed upregulation of genes related to therapy resistance, apoptotic regulation and epithelial-mesenchymal transition. In addition, the SP displayed higher tumourigenic (CSC) activity than the MP as analyzed in vitro by sphere-forming capacity. We identified a SP in human PDAC and uncovered a chemoresistant and CSC-associated phenotype. This SP may represent a new therapeutic target in pancreatic cancer. Clinicaltrials.gov NCT00936104

    AIM: To investigate the intracellular apoptotic signals engaged by resveratrol in three gastric adenocarcinoma cancer cell lines, two of which (AGS and SNU-1) express p53 and one (KATO-Ⅲ) with deleted p53.METHODS: Nuclear fragmentation was used to quantitate apoptotic cells; caspase activity was determined by photometric detection of cleaved substrates; formation of oxidized cytochrome C was used to measure cytochrome C activity, and Western blot analysis was used to determine protein expression.RESULTS: Gastric cancer cells, irrespective of their p53 status, responded to resveratrol with fragmentation of DNA and cleavage of nuclear lamins A and B and PARP, Resveratrol, however, has no effect on mitochondria-associated apoptotic proteins Bcl-2, Bclxl, Bax, Bid or Smac/Diablo, and did not promote subcellular redistribution of cytochrome C, indicating that resveratrol-induced apoptosis of gastric carcinoma cells does not require breakdown of mitochondrial membrane integrity. Resveratrol up-regulated p53 protein in SNU-1 and AGS cells but there was a difference in response of intracellular apoptotic signals between these cell lines.SNU-1 cells responded to resveratrol treatment with down-regulation of survivin, whereas in AGS and KATO-Ⅲ cells resveratrol stimulated caspase 3 and cytochrome C oxidase activities.CONCLUSION: These findings indicate that even within a specific cancer the intracellular apoptotic signals engaged by resveratrol are cell type dependent and suggest that such differences may be related to differentiation or lack of differentiation of these cells.

  14. Staging of pancreatic ductal adenocarcinoma using dynamic MR imaging

    Single breath-hold gradient echo images were obtained before and immediately after bolus intravenous administration of Gd-DTPA (dynamic MR imaging) in the study of the pancreas. Of 37 patients with pathologically proved pancreatic ductal adenocarcinoma, seventeen patients who underwent both dynamic MR imaging studies and curative surgery were included in this study. Correlations between histologic findings in the resected specimens and MR images were analyzed as to tumor extension and staging according to the General Rules for the Study of Pancreatic Cancer (4th Edition) published by the Japan Pancreas Society. In comparison with conventional MR images, dynamic MR imaging improved the detectability of pancreatic carcinoma and delineation of the vasculature by clarifying the margin of the tumor and the vessels. Nonenhanced T1-weighted imaging is the best sequence to estimate peripancreatic tumor extension, because the contrast between the tumor and peripancreatic fat deteriorates with the use of contrast material. There is a tendency to overestimate vascular invasion on MR images, the reason for which is considered to be the contractive nature of fibrotic change induced by pancreatic carcinoma. The diagnostic efficacy of lymph node metastasis remains insufficient on MR images because some cases show no enlargement of lymph nodes in spite of the existence of pathological metastasis. Our results suggest that dynamic MR imaging has the advantage of improving the conspicuity of the tumor and the vasculature. (author)

  16. Combined modality treatment of localized unresectable adenocarcinoma of the pancreas

    Since 1978, 86 patients with unresectable localized adenocarcinoma of the pancreas have been treated with a combined modality program using radioactive iodine 125-Implantation, external beam radiation, and systemic chemotherapy. Three treatment approaches were used with sequential modifications of the technique based on the course of disease and patterns of failure. Group 1 was comprised of 13 patients treated with a combination of implantation followed by a planned external radiation dose of 5000 to 6000 cGy delivered in 6 weeks. Group 2 included patients treated as in Group 1 followed by adjuvant chemotherapy. The most recent group of 54 patients, Group 3, has been treated since 1981 with implantation into the tumor of radioactive Iodine 125 seeds (12000 cGy minimal peripheral dose), perioperative chemotherapy (5-FU, Mito-C), and external beam irradiation (5000-5500 cGy) followed by further chemotherapy. Incidence of perioperative mortality has been reduced from 31% (10/32) in Groups 1 and 2 to 7% (4/54) in Group 3. Clinical local control of tumor has been excellent in all three groups (84%). Analysis of the Group 3 results indicate that the problem of distant metastasis, in spite of adjuvant chemotherapy, still remains overwhelming (64%)--especially to the liver--and requires development of more effective regimens. Median survival in the three groups of patients is 5.5, 11.3, and 12.5 months. The 2-year survival is 0, 15, and 22%, retrospectively in the three groups

  17. Stem cells as the root of pancreatic ductal adenocarcinoma

    Emerging evidence suggests that stem cells play a crucial role not only in the generation and maintenance of different tissues, but also in the development and progression of malignancies. For the many solid cancers, it has now been shown that they harbor a distinct subpopulation of cancer cells that bear stem cell features and therefore, these cells are termed cancer stem cells (CSC) or tumor-propagating cells. CSC are exclusively tumorigenic and essential drivers for tumor progression and metastasis. Moreover, it has been shown that pancreatic ductal adenocarcinoma does not only contain one homogeneous population of CSC rather than diverse subpopulations that may have evolved during tumor progression. One of these populations is called migrating CSC and can be characterized by CXCR4 co-expression. Only these cells are capable of evading the primary tumor and traveling to distant sites such as the liver as the preferred site of metastatic spread. Clinically even more important, however, is the observation that CSC are highly resistant to chemo- and radiotherapy resulting in their relative enrichment during treatment and rapid relapse of disease. Many laboratories are now working on the further in-depth characterization of these cells, which may eventually allow for the identification of their Achilles heal and lead to novel treatment modalities for fighting this deadly disease.

  18. Malignant priapism: Penile metastasis originating on a primary prostate adenocarcinoma

    2015-01-01

    Full Text Available Malignant priapism is a definition invented in 1938 by Peacock, defined as a persistent erection, not related with sexual activity, caused by cavernous sinus and associated venous systems invasion with malignant cells. Penile secondary lesions are rare entities. Primary locations are usually the pelvic cavity organs, namely the prostate and the bladder as the most common ones. Priapism as a first manifestation of these kinds of lesions is even rarer. The aim was to present a 52-year-old patient harboring a penile metastasis that originated in the primary prostate adenocarcinoma, manifesting itself as a "common" priapism. The patient referred to the emergency room presenting with a priapism and nodules at the coronal sulcus, without previous similar episodes. His evolution until properly diagnosed was catastrophic with multiple lymph nodes, bone and organ involvement, and with his demise soon after from serious bleeding and congestive heart failure, almost 2 months after he first came to the emergency room. We review the literature concerning malignant priapism, diagnosis, and current treatment and survival perspectives.

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

    This report delivers a comprehensive genetic alteration profile of lung adenocarcinomas (LADC) driven by ALK, RET, and ROS1 oncogene fusions. These tumors are difficult to study because of their rarity. Each drives only a low percentage of LADCs. Whole-exome sequencing and copy-number variation analyses were performed on a Japanese LADC cohort (n = 200) enriched in patients with fusions (n = 31, 15.5%), followed by deep resequencing for validation. The driver fusion cases showed a distinct profile with smaller numbers of nonsynonymous mutations in cancer-related genes or truncating mutations in SWI/SNF chromatin remodeling complex genes than in other LADCs (P < 0.0001). This lower mutation rate was independent of age, gender, smoking status, pathologic stage, and tumor differentiation (P < 0.0001) and was validated in nine fusion-positive cases from a U.S. LADCs cohort (n = 230). In conclusion, our findings indicate that LADCs with ALK, RET, and ROS1 fusions develop exclusively via their dependence on these oncogene fusions. The presence of such few alterations beyond the fusions supports the use of monotherapy with tyrosine kinase inhibitors targeting the fusion products in fusion-positive LADCs. PMID:25855381

    Oesophageal adenocarcinoma (EAC) incidence is rapidly increasing in Western countries. A better understanding of EAC underpins efforts to improve early detection and treatment outcomes. While large EAC exome sequencing efforts to date have found recurrent loss-of-function mutations, oncogenic driving events have been underrepresented. Here we use a combination of whole-genome sequencing (WGS) and single-nucleotide polymorphism-array profiling to show that genomic catastrophes are frequent in EAC, with almost a third (32%, n=40/123) undergoing chromothriptic events. WGS of 22 EAC cases show that catastrophes may lead to oncogene amplification through chromothripsis-derived double-minute chromosome formation (MYC and MDM2) or breakage-fusion-bridge (KRAS, MDM2 and RFC3). Telomere shortening is more prominent in EACs bearing localized complex rearrangements. Mutational signature analysis also confirms that extreme genomic instability in EAC can be driven by somatic BRCA2 mutations. These findings suggest that genomic catastrophes have a significant role in the malignant transformation of EAC. PMID:25351503

    Small bowel cancer represents less than 5% of all gastrointestinal cancers, while small bowel adenocarcinoma (SBA) accounts for about one third of all cancers of the small bowel. Although SBA frequently appears sporadically, some diseases are risk factors, such as Crohn's disease and some genetic predispositions to cancer. Progress in the identification of molecular alterations suggests some similarities in carcinogenesis between SBA and colorectal cancer. Evidence levels for the treatment and prognosis of these tumors are insufficient because of the scarcity of this disease and the absence of randomized trials. Chemotherapy based on fluoropyrimidine plus a platinum salt appears to be the most effective treatment regimen in non-randomized prospective trials for advanced SBA. Targeted therapy, against the angiogenic pathway or the epidermal growth factor receptor (EGFR) pathway, for example, is not yet established, but seems promising given the over-expression of vascular epithelial growth factor (VEGF)-A or EGFR observed in SBA. Phase I and II studies are currently evaluating the safety and efficacy of these targeted therapies in SBA treatment. The low incidence of SBA should promote the development of international collaborations to improve our knowledge of the biological mechanisms underlying these tumors and to set up therapeutic trials.

  3. Mutants of human colon adenocarcinoma, selected for thymidylate synthase deficiency

    GC3/c1 human colon adenocarcinoma cells were treated with the mutagen ethyl methane sulfonate, and three clones deficient in thymidylate synthase activity were selected and characterized. Growth in medium deficient in thymidine caused cell death in two clones (TS-c1 and TS-c3), whereas one clone (TS-c2) showed limited growth. Growth correlated with thymidine synthase activity and 5-fluoro-2'-deoxyuridine 5'-monophosphate-binding capacity and with incorporation of 2'-deoxy[6-3H]uridine into DNA. In the presence of optimal thymidine, growth rates were only 5-18% that of the parental clone (GC3/c1), which grew equally well in thymidine-deficient or -replete medium. Analysis of poly(A)+ RNA showed normal levels of a 1.6-kilobase transcript in TS-c1 and TSminusc2 but decreased levels in TS-c3. Clone TSminusc3 was 32-, 750-, and >100,000-fold more resistant than the parental clone to 5-fluorouracil, 5-fluoro-2'-deoxyuridine, and methotrexate, respectively. When inoculated into athymic nude mice, each TS- clone produced tumors, demonstrating continued ability to proliferate in vivo

  4. The HSP90 Inhibitor Ganetespib Radiosensitizes Human Lung Adenocarcinoma Cells

    The molecular chaperone HSP90 is involved in stabilization and function of multiple client proteins, many of which represent important oncogenic drivers in NSCLC. Utilization of HSP90 inhibitors as radiosensitizing agents is a promising approach. The antitumor activity of ganetespib, HSP90 inhibitor, was evaluated in human lung adenocarcinoma (AC) cells for its ability to potentiate the effects of IR treatment in both in vitro and in vivo. The cytotoxic effects of ganetespib included; G2/M cell cycle arrest, inhibition of DNA repair, apoptosis induction, and promotion of senescence. All of these antitumor effects were both concentration- and time-dependent. Both pretreatment and post-radiation treatment with ganetespib at low nanomolar concentrations induced radiosensitization in lung AC cells in vitro. Ganetespib may impart radiosensitization through multiple mechanisms: such as down regulation of the PI3K/Akt pathway; diminished DNA repair capacity and promotion of cellular senescence. In vivo, ganetespib reduced growth of T2821 tumor xenografts in mice and sensitized tumors to IR. Tumor irradiation led to dramatic upregulation of β-catenin expression in tumor tissues, an effect that was mitigated in T2821 xenografts when ganetespib was combined with IR treatments. These data highlight the promise of combining ganetespib with IR therapies in the treatment of AC lung tumors

    Esophageal adenocarcinoma arising from ectopic gastric mucosa (EGM) is extremely rare. We describe here two Japanese patients with adenocarcinoma of the cervical esophagus arising from EGM. Case 1 is a 62-year-old man who had slightly red EGM in the cervical esophagus on upper gastrointestinal endoscopy (UGE). Because the biopsy showed atypical glands that were suspicious for adenocarcinoma, endoscopic submucosal dissection was performed. Histopathological examination revealed that the lesion was a well-differentiated adenocarcinoma (pT1a MM). Lymphovascular invasion was absent, and the margins were free from carcinoma. Case 2 is a 57-year-old man who had an elevated lesion with a bleeding tendency in an area of EGM in the cervical esophagus on UGE. Adenocarcinoma was diagnosed in the biopsy. Because of the presence of enlarged lymph nodes (#106recL), preoperative chemoradiotherapy was performed to reduce the size of the adenocarcinoma and lymph nodes prior to resection of the cervical esophagus and reconstruction with free jejunal grafts. Histopathological examination revealed moderately differentiated adenocarcinoma (0-I, pT2N1M0, pStage II). In both cases, adenocarcinoma was surrounded by EGM, which led to the diagnosis of EGM-derived esophageal adenocarcinoma. Here, we report its immunohistochemical characteristics in the present cases and discuss the histogenesis. PMID:26476962

    Somatic mutations in epidermal growth factor receptor (EGFR) tyrosine kinase domain, particularly deletions in exon 19 and point mutation in exon 21, are associated with clinical outcome in patients with lung adenocarcinoma, suggesting that EGFR mutation would have an important role in clinical decision making. DNA was extracted from the excised specimens of 60 lung adenocarcinoma patients with phenol-chloroform and ethanol precipitation. Exon 19 and 21 were amplified by PCR, and direct sequenced from both sense and antisense directions. EGFR somatic mutations were present in 13 of 60 patients (21.67%), including seven cases of in-frame deletion in exon 19 around codon 746 and six cases of amino acid substitution in exon 21. Exon 21 mutation is more frequent in adenocarcinomas with bronchi-alveolar component than exon 19 deletions. Mutations were more prevalent in well-differentiated adenocarcinomas (9/27, 33.33%) than in moderate to poor-differentiated adenocarcinomas (4/33, 12.12%) (P < 0.05). Adenocarcinomas with bronchi-alveolar components had higher mutation frequency (8/22,36. 36%) than those without bronchi-alveolar components (5/38, 13.16%) (P < 0.05). In this study, female patients had more mutation rate than male patients. This trend was also observed in the patients with pathologic stage I-II compared with stage III-IV, but neither of them was statistically significant. Patients with cisplatin-based adjuvant chemotherapy had no significantly prolonged survival compared with single radical resection. But patients with EGFR mutation had relative longer survival. In conclusion, our study suggest that EGFR mutations may be a valuable prognostic factor for disease free survival of surgically treated lung adenocarcinoma patients independently from adjuvant chemotherapy.

However, the clinical significance of FGF1 in gastric adenocarcinoma has not been explored.Patients and methods: In our experiments, we systematically evaluated FGF1 expression in 178 cases of gastric adenocarcinoma with immunohistochemistry, and subsequently analyzed the correlation between FGF1 expression and clinicopathologic features. Moreover, FGF1 expression in tumor tissue and corresponding adjacent tissue was detected and compared by real-time polymerase chain reaction. The Kaplan–Meier method and the Cox-regression model were used with univariate and multivariate analysis, respectively, to evaluate the prognostic value of FGF1 in gastric adenocarcinoma.Results: Higher FGF1 expression rate is 56.7% (101/178 in gastric adenocarcinoma. FGF1 expression in gastric adenocarcinoma was significantly higher than adjacent tissue (P<0.0001. Expression of FGF1 is significantly associated with lymph node invasion (P<0.001, distant metastasis (P=0.013, and differentiation (P=0.015. Moreover, FGF1 overexpression was closely related to unfavorable overall survival rate (P=0.021, and can be identified to be an independent unfavorable prognostic factor (P=0.004.Conclusion: FGF1 is an independent prognostic factor, indicating that FGF1 could be a potential molecular drug target in gastric adenocarcinoma.Keywords: fibroblast growth factor 1, gastric adenocarcinoma, prognosis, biomarker, lymph node, gene fusion

    Full Text Available The aim of this study was to clarify the significance of DNA methylation alterations at precancerous stages of lung adenocarcinoma. Using single-CpG resolution Infinium array, genome-wide DNA methylation analysis was performed in 36 samples of normal lung tissue obtained from patients without any primary lung tumor, 145 samples of non-cancerous lung tissue (N obtained from patients with lung adenocarcinomas, and 145 samples of tumorous tissue (T. Stepwise progression of DNA methylation alterations from normal lung tissue to non-cancerous lung tissue obtained from patients with lung adenocarcinomas, and then tumorous tissue samples, was observed at 3,270 CpG sites, suggesting that non-cancerous lung tissue obtained from patients with lung adenocarcinomas was at precancerous stages with DNA methylation alterations. At CpG sites of 2,083 genes, DNA methylation status in samples of non-cancerous lung tissue obtained from patients with lung adenocarcinomas was significantly correlated with recurrence after establishment of lung adenocarcinomas. Among such recurrence-related genes, 28 genes are normally unmethylated (average β-values based on Infinium assay in normal lung tissue samples was less than 0.2 and their DNA hypermethylation at precancerous stages was strengthened during progression to lung adenocarcinomas (Δβ(T-N>0.1. Among these 28 genes, we focused on 6 for which implications in transcription regulation, apoptosis or cell adhesion had been reported. DNA hypermethylation of the ADCY5, EVX1, GFRA1, PDE9A, and TBX20 genes resulted in reduced mRNA expression in tumorous tissue samples. 5-Aza-2'-deoxycytidine treatment of lung cancer cell lines restored the mRNA expression levels of these 5 genes. Reduced mRNA expression in tumorous tissue samples was significantly correlated with tumor aggressiveness. These data suggest that DNA methylation alterations at precancerous stages determine tumor aggressiveness and outcome through silencing of

    BACKGROUND In cervical adenocarcinoma, surgical treatment involves bilateral oophorectomy, which affects the long-term quality of life. The aim of our study was to access the incidence of ovarian metastasis in early-stage cervical adenocarcinoma and to suggest an algorithm for the triage of these patients to preserve the ovaries. MATERIAL AND METHODS A total 101 patients with cervical adenocarcinoma who had undergone radical hysterectomy with pelvic lymphadenectomy and bilateral oophorectomy were included in this study. Data on the clinicopathologic characteristics of the cases were collected and low risk factors for ovarian metastasis in early-stage cervical adenocarcinoma were analyzed. RESULTS The ovary metastasis rate of cervical adenocarcinoma in this study was 4.95%, while it is only 2% in stage IB1. Pathological grade, LSVI, lymph node status, tumor size, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis, while LSVI, lymph node status, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis in stage IB. Multivariate analysis revealed that LVSI and lymph node metastasis were independent risk factors for ovarian metastasis in all stages of cervical adenocarcinoma, but involvement of the junction of the cervix and the body of the uterus was an independent risk factor for ovarian metastasis in stage IB. CONCLUSIONS The incidence of ovarian metastasis in cervical adenocarcinoma is low. Our study suggests that ovarian preservation is safe and feasible in patients with no risk factors for ovarian metastasis. Further prospective studies are warranted. PMID:26852916

    Obestatin, a 23-amino acid peptide encoded by the ghrelin gene, and the GPR39 receptor were reported to be involved in the control of mitogenesis of gastric cancer cell lines; however, the relationship between the obestatin/GPR39 system and gastric cancer progression remains unknown. In the present study, we determined the expression levels of the obestatin/GPR39 system in human gastric adenocarcinomas and explored their potential functional roles. Twenty-eight patients with gastric adenocarcinomas were retrospectively studied, and clinical data were obtained. The role of obestatin/GPR39 in gastric cancer progression was studied in vitro using the human gastric adenocarcinoma AGS cell line. Obestatin exogenous administration in these GPR39-bearing cells deregulated the expression of several hallmarks of the epithelial-mesenchymal transition (EMT) and angiogenesis. Moreover, obestatin signaling promoted phenotypic changes via GPR39, increasingly impacting on the cell morphology, proliferation, migration and invasion of these cells. In healthy human stomachs, obestatin expression was observed in the neuroendocrine cells and GPR39 expression was localized mainly in the chief cells of the oxyntic glands. In human gastric adenocarcinomas, no obestatin expression was found; however, an aberrant pattern of GPR39 expression was discovered, correlating to the dedifferentiation of the tumor. Altogether, our data strongly suggest the involvement of the obestatin/GPR39 system in the pathogenesis and/or clinical outcome of human gastric adenocarcinomas and highlight the potential usefulness of GPR39 as a prognostic marker in gastric cancer.

    AIM: To test whether antioxidant treatment could prevent the progression of Barrett's esophagus to adenocarcinoma.METHODS: In a rat model of gastroduodenoesophageal reflux by esophagojejunal anastomosis with gastric preservation, groups of 6-10 rats were randomized to receive treatment with superoxide dismutase (SOD) or vehicle and followed up for 4 mo. Rat's esophagus was assessed by histological analysis, superoxide anion and peroxinitrite generation, SOD levels and DNA oxidative damage.RESULTS: All rats undergoing esophagojejunostomy developed extensive esophageal mucosal ulceration and inflammation by mo 4. The process was associated with a progressive presence of intestinal metaplasia beyondthe anastomotic area (9% 1st mo and 50% 4th mo) (94% at the anastomotic level) and adenocarcinoma(11% 1st mo and 60% 4th mo). These changes were associated with superoxide anion and peroxinitrite mucosal generation, an early and significant increase of DNA oxidative damage and a significant decrease in SOD levels (P<0.05). Exogenous administration of SOD decreased mucosal superoxide levels, increased mucosal SOD levels and reduced the risk of developing intestinal metaplasia beyond the anastomotic area (odds ratio = 0.326; 95%CI: 0.108-0.981; P = 0.046),and esophageal adenocarcinoma (odds ratio = 0.243;95%CI: 0.073-0.804; P = 0.021).CONCLUSION: Superoxide dismutase prevents the progression of esophagitis to Barrett's esophagus and adenocarcinoma in this rat model of gastrointestinal reflux, supporting a role of antioxidants in the chemoprevention of esophageal adenocarcinoma.

  13. Surgical implications of the new IASLC/ATS/ERS adenocarcinoma classification.

    2012-02-01

    A new adenocarcinoma classification was recently introduced by a joint working group of the International Association for the Study of Lung Cancer (IASLC), American Thoracic Society (ATS) and European Respiratory Society (ERS). A distinction is made between pre-invasive lesions, and minimally invasive and invasive adenocarcinoma. The confusing term "bronchioloalveolar carcinoma" is not used any more and new subcategories include adenocarcinoma in situ and minimally invasive adenocarcinoma. Due to a renewed interest in screen-detected nodules and early-stage lung cancers of <2 cm, this classification also has profound implications for thoracic surgeons. In this article, surgical topics are discussed: the role of a minimally invasive approach, especially video-assisted thoracic surgery, limited resection for early-stage lung cancer, the extent of lymph node dissection, the accuracy of intraoperative frozen section analysis, management of multiple lung nodules and prognostic factors in operated patients. Specific key issues are presented based on the current evidence and areas of surgical uncertainty are defined providing a basis for further studies. Thoracic surgeons will play a major role in the application and global introduction of this new adenocarcinoma classification. The remaining controversies regarding the precise diagnosis and management of early-stage lesions will have to be resolved by multidisciplinary and international collaboration. PMID:21828029

    This study was conducted on mouse lung adenocarcinoma tissues that were formalin-treated and paraffin-embedded 25 years ago to investigate the large gene deletions of mRb and p53 in B6CF{sub 1} male mice. A total of 80 lung tissue samples from irradiated mice and 40 lung samples from nonirradiated controls were randomly selected and examined in the mRb portion of this study. The results showed a significant (P < 0.05) higher percentage of mRb deletions in lung adenocarcinomas from mice exposed to 60 once-weekly {gamma}-ray doses than those from mice receiving 24 once-weekly {gamma}-ray doses at low doses and low dose rates; however, the percentage was not significantly different (P > 0.05) from that for spontaneous lung adenocarcinomas or lung adenocarcinomas from mice exposed to single-dose {gamma} irradiation at a similar total dose. mRb fragments 3 (71%) and 5 (67%), the parts of the gene that encoded the pocket binding region of Rb protein to adenovirus E1A and SV40 T-antigen, were the most frequently deleted fragments. p53 gene deletion analysis was carried out on normal lungs and lung adenocarcinomas that were initially found to bear mRb deletions. Exons 1,4,5,6, and 9 were chosen to be analyzed.

    2-[Fluorine-18]fluoro-2-deoxy-d-glucose (FDG) uptake within the primary lesion correlates with survival on positron emission tomography (PET) studies of patients with non-small cell lung cancer. The more metabolically active the tumour, the worse the outcome. The aim of this study was to determine whether a correlation exists between aggressiveness as determined by pathology and the findings of FDG PET in pulmonary adenocarcinoma. Thirty-five patients with 38 adenocarcinomas of the lung were studied. All patients underwent thoracotomy within 4 weeks of the FDG PET study. For semiquantitative analysis, standardized uptake values (SUVs) were calculated. Patients were classified into high SUV (> or = 4.0) and low SUV (permeation). The mean SUV of aggressive adenocarcinomas (4.36+/-1.94, n = 22) was higher than that of non-aggressive ones (1.53+/-0.88, n = 16) (P PET in adenocarcinoma of the lung. FDG PET may be used as a non-invasive diagnostic technique in measuring aggressiveness and prognosis in patients with pulmonary adenocarcinoma. PMID:11039452

  16. Focal pancreatic enlargement: differentiation between pancreatic adenocarcinoma and focal pancreatitis on CT and ERCP

    To differentiate the pancreatic adenocarcinoma from focal pancreatitis on CT and ERCP in cases of focal pancreatic enlargement. We analysed CT findings of 66 patients of pancreatic adenocarcinoma (n = 45) or focal pancreatitis (n = 21) with respect to size, density, calcification, pancreatic or biliary duct dilatation, fat plane obliteration around the vessels, direction of retroperitoneal extension, lymphadenopathy, pseudocyst formation and atrophy of pancreas. ERCP available in 48 patients were analysed in respect to morphologic appearance of CBD and pancreatic duct, and distance between the two ducts. The patients in focal pancreatitis were younger with more common history of alcohol drinking. There was no statistical difference in calcifications of the mass (18% in the adenocarcinoma, 33% in the focal pancreatitis), but a tendency of denser, larger number of calcifications was noted in focal pancreatitis. The finding of fat plane obliteration around the vessels were more common in pancreatic adenocarcinoma, and fascial thickenings were more prominent in focal pancreatitis, although not statistically significant. On ERCP, there were no differential points of CBD, pancreatic duct morphology, but distance between the two ducts at the lesion center was more wider in focal pancreatitis. Differentiating focal pancreatitis from pancreatic adenocarcinoma is difficult. However, we should consider the possibility of focal pancreatitis in cases of patients with young age, having alcoholic history in association with CT findings of large numbers of and dense calcifications, and ERCP findings of prominent separation of two duct at the lesion center

    To determine the clinical, histopathologic and imaging features of pancreatic adenocarcinomas without secondary signs on dynamic CT. Seventy patients (mean age 70 years) with histologically proven pancreatic adenocarcinoma underwent preoperative contrast material-enhanced multiphasic multidetector CT before pancreatic resection. In each patient, clinical data including carbohydrate antigen 19-9, frequency of isoattenuating tumours, and presence of secondary signs and histopathologic findings such as tumour location, tumour stage, and microscopic infiltrative growth grade were evaluated. Ten tumours (14 %) were without secondary signs, and 60 (86 %) were with secondary signs. Tumours without and with secondary signs were located in the uncinate process in 5 (50 %) and 3 (5 %), head in 3 (30 %) and 29 (48 %), body in 2 (20 %) and 22 (37 %), and tail in 0 (0 %) and 6 (10 %), respectively (p =.001). The frequency of isoattenuating pancreatic adenocarcinomas without secondary signs was significantly higher than those with secondary signs (p = 0.034). The tumour stage of pancreatic adenocarcinomas without secondary signs was earlier than that in tumours with secondary signs (p = 0.041). Pancreatic adenocarcinomas without secondary signs is characterized by the presence of uncinate and isoattenuating tumours and earlier tumour stage compared to tumours with secondary signs. (orig.)

    Purpose To describe the postoperative progressive course of advanced-stage adenocarcinoma arising from a mature cystic teratoma (MCT) and review the literature regarding this disease. Methods A 59-year-old woman visited our hospital with an abdominal mass. Laparotomy showed enlargement of the left ovary and dissemination throughout the abdominal and pelvic cavities. The diagnosis was FIGO stage IIIB adenocarcinoma arising from a MCT. We report this case in detail with a review of the literature. Results A literature search yielded 9 cases of stage III adenocarcinoma with malignant transformation. Six of these 9 patients died within 12 months after diagnosis. Of the 8 patients who underwent postoperative chemotherapy, 3 survived for over 39 months. The review indicates that prognosis of adenocarcinoma is as poor as that for squamous cell carcinoma arising from a MCT. Conclusions In general, as with this case, prognosis of advanced adenocarcinoma associated with a MCT is poor. However, we should be aware that not all patients are resistant to chemotherapy.

    Full Text Available Context Combination chemotherapy with FOLFIRINOX (oxaliplatin, irinotecan, fluorouracil, and leucovorin was shown to beeffective in a large phase III trial. Objective The purpose of this study was to examine the tolerance and effectiveness ofFOLFIRINOX as practiced outside of the confines of a clinical trial and to document any dose modifications used by practicing oncologists. Methods Data on patients with all stages of pancreatic adenocarcinoma treated with FOLFIRINOX at three institutions was analyzed for efficacy, tolerance, and use of any dose modifications. Results Total of 61 patients was included in this review. Median age was 58 years (range: 37 to 72 years, 33 were male (54.1% and majority had ECOG performance of 0 or 1 (86.9%, 53 patients. Thirty-eight (62.3% had metastatic disease, while 23 (37.7% were treated for locally advanced or borderline resectable disease. Patients were treated with a median number of four cycles of FOLFIRINOX, with dose modifications in 58.3% (176/302 of all cycles. Ten patients had stable disease (16.4%, four had a partial response (6.6% while eight had progressive disease (13.1% on best imaging following therapy. Median progression-free survival and overall survival were 7.5 months and 13.5 months, respectively. The most common grade 3-4 adverse event was neutropenia at 19.7% (12 cases, with 4.9% (3 cases rate of febrile neutropenia. Twenty-one patients (34.4% were hospitalized as a result of therapy but there were no therapy-related deaths. Twentythree (37.7% had therapy eventually discontinued as a result of adverse events. Conclusion Despite substantial rates of adverse events and use of dose modifications, FOLFIRINOX was found to be clinically effective in both metastatic and non-metastatic patients. Regimen toxicity did not detract from overall response and survival.

    AIM: To investigate the extent of oxidative stress in preneoplastic and neoplastic gastric mucosa in relation to their pathological criteria and histological subtypes.METHODS: A total of 104 gastric adenocarcinomas from 98 patients (88 infiltrative and 16 intraepithelial tumors)were assessed immunohistochemically for expression of iNOS and occurrence of nitrotyrosine (NTYR)-containing proteins and 8-hydroxy-2'-deoxyguanosine (8-OHdG)-containing DNA, as markers of NO production and damages to protein and DNA.RESULTS: Tumor cells staining for iNOS, NTYR and 8-OH-dG were detected in 41%, 62% and 50% of infiltrative carcinoma, respectively. The three markers were shown for the first time in intraepithelial carcinoma.The expression of iNOS was significantly more frequent in tubular carcinoma (TC) compared to diffuse carcinoma (DC) (54% vs 18%; P=0.008) or in polymorphous carcinoma (PolyC) (54% vs 21%; P=0.04). NTYR staining was obviously more often found in TC than that in PolyC (72% vs 30%; P=0.03). There was a tendency towards a higher rate of iNOS staining when distant metastasis (pM) was present. In infiltrative TC, the presence of oxidative stress markers was not significantly correlated with histological grade, density of inflammation, the depth of infiltration (pT), lymph nodes dissemination (pN) and pathological stages (pTNM).CONCLUSION: The iNOS-oxidative pathway may play an important role in TC, but moderately in PolyC and DC.DNA oxidation and protein nitration occur in the three subtypes. Based on the significant differences of NTYR levels, TC and PolyC appear as two distinct subtypes.

    Despite advances and investments in translation research, clinical trials and health service in general, there is no significant impact on the survival of most patients diagnosed with advanced pancreatic adenocarcinoma. It is broadly recognized though that there is a small minority of patients who really benefit from particular treatments for reason usually not well understood. Light to this fact is gradually shed by developments in the field of pharmacogenomics, which plays pivotal role in what we call individualized medicine. In that perspective, it is of most importance to present the significant developments in pharmacogenomics announced in the recent 2013 American Society of Clinical Oncology Annual Meeting. First, the predictive role of hENT1, which codes for a gemcitabine transporter into cells, was highlighted and might help us decide whether we benefit from gemcitabine or 5-fluorouracil in the adjuvant setting (Abstract #4006). Second, authors presented the negative predictive role of SPARC stroma and cytoplasmic expression in patients treated with adjuvant gemcitabine (within the CONCO-001 study) as they reported poor outcome of those having high expression, not seen in patients on observation (Abstract #4016). Finally, a study which might be a basis for future strategies and as great food for scientific thought suggested that selection of cytotoxic treatment based on gene expression profiling is feasible in clinical practice and may help improve treatment efficacy as well as predict for drug resistance (Abstract #4017). Of course, there is a long way to go before implementation of these genomic findings, with the exception of hENT1 which seems to be close for clinical use. PMID:23846927

    2015-08-01

    Minimally invasive surgery (MIS) for pancreatic adenocarcinoma has found new avenues for performing pancreaticoduodenectomy (PD) procedures, a historically technically challenging operation. Multiple studies have found laparoscopic PD to be safe, with equivalent oncologic outcomes as compared to open PD. In addition, several series have described potential benefits to minimally invasive PD including fewer postoperative complications, shorter hospital length of stay, and decreased postoperative pain. Yet, despite these promising initial results, laparoscopic PDs have not become widely adopted by the surgical community. In fact, the vast majority of pancreatic resections performed in the United States are still performed in an open fashion, and there are only a handful of surgeons who actually perform purely laparoscopic PDs. On the other hand, robotic assisted surgery offers many technical advantages over laparoscopic surgery including high-definition, 3-D optics, enhanced suturing ability, and more degrees of freedom of movement by means of fully-wristed instruments. Similar to laparoscopic PD, there are now several case series that have demonstrated the feasibility and safety of robotic PD with seemingly equivalent short-term oncologic outcomes as compared to open technique. In addition, having the surgeon seated for the procedure with padded arm-rests, there is an ergonomic advantage of robotics over both open and laparoscopic approaches, where one has to stand up for prolonged periods of time. Future technologic innovations will likely focus on enhanced robotic capabilities to improve ease of use in the operating room. Last but not least, robotic assisted surgery training will continue to be a part of surgical education curriculum ensuring the increased use of this technology by future generations of surgeons.

  4. Prognostic characteristics of surgical stage I endometrial adenocarcinoma

    Purpose: To evaluate and correlate the expression of pathologic characteristics, flow cytometric DNA content analysis, and estrogen and progesterone receptor levels with survival in patients with surgical Stage I endometrial carcinoma. Methods and Materials: Hospital tumor registry records were surveyed, and this identified 232 patients diagnosed with endometrial adenocarcinoma between July 1, 1989, and December 30, 1993. DNA content analysis was performed on either paraffin-embedded or fresh tissue samples. Survival was calculated from the date of diagnosis by the Kaplan-Meier method. Postoperative irradiation (whole pelvis external beam therapy and low dose rate vaginal cuff brachytherapy) was delivered to patients felt to be at high risk of failure. Results: One hundred seventy-one patients had Stage I tumors and were available for analysis. Patients with Stage IC tumors had a statistically significant lower survival rate compared to patients with Stages IA or IB (p = 0.03 and p < 0.01, respectively). Patients with DNA content diploid tumors had a slightly increased (but nonsignificantly so) survival compared to patients with non-DNA content diploid tumors (p = 0.12). Logistic regression analysis failed to identify an independent prognostic factor that could predict for disease specific survival in patients with Stage I cancers. Conclusion: Logistic regression analysis did not identify a single independent prognostic factor in patients with Stage I tumors. Pathologic characteristics reported to predict survival advantage correlated with pathologic stage. Additional translational research is needed to identify molecular characteristics of tumors that may indicate more aggressive treatment for patients at high risk for recurrence

  5. Treatment and clinical behavior of endometrial endometrioid adenocarcinoma

    Cases of endometrial carcinoma treated in a university hospital between 1986 and 1998 were analyzed. More specifically, cases of endometrial carcinoma treated at Kumamoto University Hospital during the past 13 years were analyzed in terms of additional treatment given as adjuvant therapy after surgery. Among the total of 175 cases of endometrial carcinoma, surgery was the primary treatment modality in 173 (98.9%) and the other 2 (1.1%) were treated by chemotherapy and/or radiotherapy without surgery. Of the 173 surgical cases, 158 (91.4%) were cases of endometrioid adenocarcinoma, and after excluding the cases of double cancer, the remaining 147 cases were included in the analysis. At Kumamoto University hospital, radical hysterectomy and pelvic lymphadenectomy have been performed in cases in which cervical invasion is indicated by hysteroscopy and/or MRI, invasion of the muscle coat of the uterus appears on MRI images, and in which carcinoma with specific histology (e.g., serous adenocarcinoma) or anaplastic endometrioid adenocarcinoma is seen. Semi-radical hysterectomy and pelvic lymphadenectomy have been considered to be indicated in all other cases. Adjuvant chemotherapy and radiotherapy after surgery has been indicated for cases in which invasion of the muscle coat of the uterus is to a depth of more than half its thickness, stromal invasion of the cervix is seen, or invasion of the serosa or metastasis to the uterine adnexae or lymph nodes is seen. Patients were externally irradiated with a dose of 50 Gy to the whole pelvis as adjuvant radiotherapy. The follow-up period ranged from 4 to 148 months. Of the 147 cases, 105 (71.4%) were treated by hysterectomy alone and the other 42 received adjuvant therapy (chemotherapy in 27 cases, radiotherapy in 15 cases). All stage Ia patients (16 cases) survived, and none were given additional therapy. Only 4.8% of the stage Ib cases (62) and 7.1% of the stage 2a cases (14) received adjuvant therapy, and no recurrences

    To determine whether quantitative analysis of iodine-enhanced images generated from dual-energy CT (DECT) have added value in distinguishing invasive adenocarcinoma from non-invasive or minimally invasive adenocarcinoma (MIA) showing ground-glass nodule (GGN). Thirty-four patients with 39 GGNs were enrolled in this prospective study and underwent DECT followed by complete tumour resection. Various quantitative imaging parameters were assessed, including virtual non-contrast (VNC) imaging and iodine-enhanced imaging. Of all 39 GGNs, four were adenocarcinoma in situ (AIS) (10 %), nine were MIA (23 %), and 26 were invasive adenocarcinoma (67 %). When assessing only VNC imaging, multivariate analysis revealed that mass, uniformity, and size-zone variability were independent predictors of invasive adenocarcinoma (odds ratio [OR] = 19.92, P = 0.02; OR = 0.70, P = 0.01; OR = 16.16, P = 0.04, respectively). After assessing iodine-enhanced imaging with VNC imaging, both mass on the VNC imaging and uniformity on the iodine-enhanced imaging were independent predictors of invasive adenocarcinoma (OR = 5.51, P = 0.04 and OR = 0.67, P < 0.01). The power of diagnosing invasive adenocarcinoma was improved after adding the iodine-enhanced imaging parameters versus VNC imaging alone, from 0.888 to 0.959, respectively (P = 0.029). Quantitative analysis using iodine-enhanced imaging metrics versus VNC imaging metrics alone generated from DECT have added value in distinguishing invasive adenocarcinoma from AIS or MIA. (orig.)

  10. Targeting key signalling pathways in oesophageal adenocarcinoma: A reality for personalised medicine?

    Richard R Keld; Yeng S Ang

    2011-01-01

    Cancer treatments are rapidly changing. Curative treatment for oesophageal adenocarcinoma currently involves surgery and cytotoxic chemotherapy or chemoradiotherapy.Outcomes for both regimes are generally poor as a result of tumor recurrence. We have reviewed the key signalling pathways associated with oesophageal adenocarcinomas and discussed the recent trials of novel agents that attempt to target these pathways. There are many trials underway with the aim of improving survival in oesophageal cancer. Currently,phase 2 and 3 trials are focused on MAP kinase inhibition, either through inhibition of growth factor receptors or signal transducer proteins. In order to avoid tumor resistance, it appears to be clear that targeted therapy will be needed to combat the multiple signalling pathways that are in operation in oesophageal adenocarcinomas. This may be achievable in the future with the advent of gene signatures and a combinatorial approach.

  11. The thalidomide analog, EM 12, enhances 1,2-dimethylhydrazine-induction of rat colon adenocarcinomas.

    Gershbein, L L

    1991-11-01

    Young male Sprague-Dawley rats in 3 groups were fed a basal diet supplemented with 0.10 wt. % each of thalidomide and its imide-analog of much higher teratogenicity, EM 12. Following an induction period of 17 days on the diets, all animals were injected subcutaneously with 1,2-dimethylhydrazine at 20 mg/kg for a total of 20 weekly doses and killed on week 18 after the 20th injection. The total number of colon adenocarcinomas and their occurrence in the proximal and distal portions for the thalidomide-treated rats were similar to those of the respective controls. However, the EM 12-fed group elicited statistically significant increases both in the total and ascending colon-based adenocarcinomas as compared with the control findings, in keeping with its greater teratogenicity and embryotoxicity. The numbers of small intestinal adenocarcinomas were equally higher in the imide-fed groups in contrast to the control frequency. PMID:1933837

    Pancreatic cancer costs nearly 40,000 lives in the U.S. each year and has one of the lowest survival rates among cancers. Effective treatment of pancreatic ductal adenocarcinoma is hindered by lack of a reliable biomarker. To address this challenge, aptamers were selected by cell-SELEX (Systematic Evolution of Ligands by EXponential enrichment) targeting human pancreatic ductal adenocarcinoma (PL45). Five promising aptamers presenting low Kd values and good specificity were generated. Among these five aptamers, one was tailored into a nanostructure carrying a high drug payload for specific drug delivery. The results show a viability of almost 80% for negative cells while only 50% of the target cells remained alive after 48 h incubation. These results lead to the conclusion that further research could reveal protein biomarkers specific to pancreatic adenocarcinoma, with probes available for early detection.

  13. Cerebellar metastasis from serous adenocarcinoma of the ovary mimicking pilocytic astrocytoma.

    2012-07-01

    Serous adenocarcinoma of the ovary rarely can present with solitary solid -cystic cerebellar metastasis, mimicking pilocytic astrocytoma. A middle aged women, who underwent total abdominal hysterectomy with bilateral salpingoopherectomy and adjuvant chemotherapy for ovarian adenocarcinoma, presented to us with the history of headache, vomiting, and imbalance. Contrast enhanced magnetic resonance imaging (MRI) showed solitary cerebellar, solid cystic lesion with cyst lining and solid portion enhancing on contrast which was mimicking pilocytic astrocytoma and there was no perilesional edema. Gross total excision of the cerebellar lesion was done followed by resolution of her symptoms. Histopathology showed metastatic adenocarcinoma consistent with the primary ovarian carcinoma. In patients of ovarian carcinoma, presenting with features of raised intracranial pressureICP] thorough investigations must be done to rule out metastasis. Solitary metastasis of the cerebellum because of ovarian carcinoma may mimic pilocytic astrocytoma. PMID:23293670

  15. Intestinal adenocarcinoma in a herd of farmed Sika deer (Cervus nippon): a novel syndrome.

    Kelly, P A; Toolan, D; Jahns, H

    2015-01-01

    Intestinal adenocarcinomas were identified in 76 adult deer from a closed herd of 193 breeding animals grazing pasture heavily infested with bracken fern (Pteridium aquilinum). Tumors were observed postmortem in 32 animals with rapid weight loss, and similar neoplasms were detected in a further 44 clinically normal deer at "cull." Tumors were located in distal ileum, cecum, and proximal colon and presented as single (26%) or multiple (74%), variably sized, pale-gray, firm, poorly circumscribed neoplasms with associated intestinal strictures. Histopathologically tumors were well-differentiated, locally infiltrative, low-grade adenocarcinomas of tubular (51%), mucinous (33.5%), or mixed (15.5%) types. Extraintestinal metastases were not observed. The high incidence of intestinal adenocarcinoma within this herd suggests a specific and novel syndrome, and genetic and/or environmental factors may be involved in the pathogenesis. PMID:24503440

    2013-12-01

    We studied a methods of assessment of a connective tissue of cervix in terms of specific volume of fibrous component and an optical density of staining of connective tissue fibers in the stroma of squamous cancer and cervix adenocarcinoma. An absorption spectra of blood plasma of the patients suffering from squamous cancer and cervix adenocarcinoma both before the surgery and in postsurgical periods were obtained. Linear dichroism measurements transmittance in polarized light at different orientations of the polarization plane relative to the direction of the dominant orientation in the structure of the sample of biotissues of stroma of squamous cancer and cervix adenocarcinoma were carried. Results of the investigation of the tumor tissues showed that the magnitude of the linear dichroism Δ is insignificant in the researched spectral range λ=280-840 nm and specific regularities in its change observed short-wave ranges.

  17. Adenocarcinoma de apêndice: relato de dois casos Appendicecal carcinoma: report of two cases

    Alexandre Cruz Henriques

    2001-10-01

    Full Text Available The authors report two cases of patients with appendix adenocarcinoma, manifested as a syndrome of abdominal tumor of unknown origin. It was not possible to perform etiological diagnosis in the preoperative period for any of them. Literature data show that large locoregional tumor is a manifestation of appendix adenocarcinoma, although acute appendicites is the most frequent clinical manifestation. Preoperative diagnosis is rare and usually performed during laparotomy or through histopathological examination of the specimen. In large tumors, total mass resection including hemicolectomy should be carried out whenever possible. Whenever diagnosis of appendix adenocarcinoma is performed by the histopathological examination of the acute appendicites specimen, re-intervention is indicated for a right hemicolectomy.

    Cancers are composed of populations of cells with distinct molecular and phenotypic features, a phenomenon termed intra-tumor heterogeneity (ITH). ITH in lung cancers has not been well studied. We applied multi-region whole exome sequencing (WES) on 11 localized lung adenocarcinomas. All tumors showed clear evidence of ITH. On average, 76% of all mutations and 20/21 known cancer gene mutations were identified in all regions of individual tumors suggesting single-region sequencing may be adequate to identify the majority of known cancer gene mutations in localized lung adenocarcinomas. With a median follow-up of 21 months post-surgery, 3 patients have relapsed and all 3 patients had significantly larger fractions of subclonal mutations in their primary tumors than patients without relapse. These data indicate larger subclonal mutation fraction may be associated with increased likelihood of postsurgical relapse in patients with localized lung adenocarcinomas. PMID:25301631

  19. Cytotoxic effects of four aescin types on human colon adenocarcinoma cell lines.

    2014-03-01

    Four types of aescin that are available on the pharmaceutical market, beta-aescin crystalline, beta-aescin amorphous, beta-aescin sodium and aescin polysulfate, have been analyzed for their cytotoxic effects on human colon adenocarcinoma (LoVo) and doxorubicin-resistant human colon adenocarcinoma cell lines (LoVo/Dx). Their cytotoxic activities were evaluated by sulforhodamine B (SRB) and methyl tetrazolium (MTT) assays. All four types of aescin exerted strong dose-dependent cytotoxicity to LoVo and, to a lesser degree, LoVo/Dx cell lines. The IC50 value for the LoVo/Dx cell line was higher, but still dose-dependent. Results from both assays demonstrated that p-aescin crystalline has the most cytotoxic activity toward human colon adenocarcinoma cell lines. PMID:24689224

    2009-01-01

    Primary neoplasms arising in the anal canal are relatively unusual. In particular, adenomas and adenocarcinomas are distinctly rare entities in this region. We describe an infiltrating, well-differentiated adenocarcinoma arising in a villous adenoma from the distal anal canal, in an otherwise healthy patient at low risk for gastrointestinal malignancy. This is the case of an octogenarian man with a several year history of hemorrhoids and intermittent rectal bleeding, more recently complaining of continuous hematochezia. Examination revealed a blood-covered pedunculated mass with a long stalk protruding from the anus. The lesion was amputated at the bedside. Microscopic evaluation revealed an infiltrating well-differentiated adenocarcinoma, arising from a villous adenoma. This was further evaluated under anesthesia and complete excision of distal anal tissue was performed. Our report is the first describing the possible malignant degeneration of a villous adenoma in the anal canal.

  1. A Case of Unsuspected Peritoneal Mesothelioma Occurring with Colonic Adenocarcinoma Masquerading as Peritoneal Metastases

    2014-01-01

    Full Text Available We report a case of synchronous primary colonic adenocarcinoma and malignant mesothelioma. A 61-year-old male presented with a six-month history of fatigue and weight loss. An abdominal computed tomography (CT scan showed a 5.8 cm partially obstructing mass in the cecum with ascites and peritoneal thickening. A biopsy of the large mass showed an adenocarcinoma. Because the patient was clinically thought to be a T4 colon carcinoma with peritoneal metastatic lesions (M1, prior to initiating chemotherapy, a debulking right hemicolectomy was performed. Resection of the colon and ileum revealed a T3N0 colonic mucinous adenocarcinoma and concurrent diffuse malignant peritoneal mesothelioma. Presenting synchronous colonic and peritoneal mesothelial primary malignancies are exceedingly rare but must be considered to prevent incorrect clinical staging.

  2. Childhood body mass index in relation to future risk of oesophageal adenocarcinoma

    Cook, M B; Freedman, N D; Gamborg, M; Sørensen, T I A; Baker, J L

    2015-01-01

    BACKGROUND: Middle-aged obese adults are at substantially elevated risk of oesophageal adenocarcinoma. It is unclear whether this risk originates earlier in life. METHODS: We assessed associations between childhood body mass index (BMI) and height-measured annually between ages 7 and 13-with adult...... oesophageal adenocarcinoma in a cohort from the Copenhagen School Health Records Register. Analyses included 255 053 children born during 1930-1971. Danish Cancer Registry linkage provided outcomes. We calculated hazard ratios (HRs) and 95% confidence intervals (CIs) using Cox proportional hazards regression....... RESULTS: During 5.4 million person-years of follow-up, 254 (216 males) incident oesophageal adenocarcinomas occurred. At each examined age, cancer risk increased linearly per unit BMI z-score, although associations were only statistically significant for ages 9-13. The HR for the age of 13 years was 1...

    Full Text Available Malignant transformation of endometriosis has been extensively described in the literature. However, extragonadal endometrioid adenocarcinoma, either de novo or arising from malignant transformation of endometriosis, is rare. The present case report describes a patient with endometrioid adenocarcinoma on the serous surface of the small intestine. A 25- year-old female with no history of endometriosis was referred to our hospital with an intrapelvic tumor. An internal examination, ultrasound, and magnetic resonance imaging revealed a round mass approximately 80 mm in diameter; however, identification of the affected organ was difficult. Because we could not rule out malignancy based on the non-specific radiologic findings, laparotomy was performed. A mass with ileal adhesions was detected intraoperatively. In addition, the uterus and bilateral adnexa appeared normal. The tumor was resected with part of the ileum. Histopathology confirmed a diagnosis of endometrioid adenocarcinoma originating from the serous surface of the small intestine.

    2010-01-01

    Full Text Available Primary adenocarcinoma is a rare and late complication following proctocolectomy and ileostomy for ulcerative colitis, familial adenomatous polyposis, Crohn's disease and multifocal colorectal cancer. We report a case of adenocarcinoma of the ileostomy occurring 48 years after proctocolectomy for ulcerative colitis. A review of the literature suggests that there are 39 cases reported in literature and this case reports the longest interval between formation of ileostomy and diagnosis of ileostomy adenocarcinoma. This case also reports lymph node metastasis to the adjacent mesenteric lymph node. The incidence of lymphnode metastasis is 15 percent as per literature. Onces diagnosis is confirmed by biopsy enblock excision with or without stomal relocation is the main stay of treatment. Patient education and regular surveillance of patients with long-standing ileostomy is recommended for early detection of this unusual cancer.

  5. The role of neoadjuvant and adjuvant treatment for adenocarcinoma of the upper gastrointestinal tract

    2011-06-01

    Full Text Available Abstract Both locally advanced adenocarcinoma of the stomach and gastro-esophageal junction are associated with poor prognosis due to the lack of effective treatment. Recently multimodal treatment consisting of neoadjuvant chemotherapy in combination with radiotherapy is reported to improve survival when compared to surgery alone. Neoadjuvant therapy in these locally advanced tumors allows for early tumor responses and the extent of tumor regression that can be achieved is considered a significant prognostic factor. This, in turn, increases the resectability of these tumors. Also due to the high frequency of lymph node metastasis, patients with locally advanced adenocarcinoma should undergo a D2 lymphadenectomy. Postoperative chemoradiation and perioperative chemotherapy have been studied in gastric adenocarcinomas and showed a survival benefit. However, the surgical techniques used in these trials are no longer considered to be standard by today's surgical practice. In addition, there are no standard recommendations for adjuvant chemotherapy or chemoradiation after R0 resection and adequate lymph node dissection.

  7. Mucinous adenocarcinoma of ascending colon associated with inflammatory disease: 2 case reports

    Cho, Young Kwon; Jeon, Hae Jeong; Park, Dong Rib; Jin, Choon Jo; Lyu, Geun Shin [Konkuk Univ. College of Medicine, Seoul (Korea, Republic of); Baek, Seung Yon [Ewha Womans Univ. College of Medicine, Seoul (Korea, Republic of)

    1997-11-01

    Inflammatory and ischemic bowel disease commonly involve a longer segment than a malignant lesion. The characteristic findings of inflammatory bowel disease are mucosal nodular hypertrophy and luminal narrowing. It has recently been reported, however, that the features of mucinous adenocarcinoma are similar to those of inflammatory bowel disease with long segmental involvement. After a brief review of the literature, we describe two cases of mucinous adenocarcinoma of the ascending colon associated with inflammatory disease. Because of long segmental involvement of the ascending colon, mucosal nodular hypertrophy and luminal narrowing, one of these was thought to be multiple villous adenoma with colitis, but was confirmed as mucinous adnocarcinoma. The other case, thought to be tuberculous enterocolitis, was confirmed as tuberculous enterocolitis associated with mucinous adenocarcinoma.

  8. Alkaline phosphatase, cytokeratin 7, cytokeratin 8 in the diagnosis of primary lung adenocarcinoma from 148 pleura fluids specimens.

    2009-05-01

    Full Text Available Adenocarcinomas are the most common cause of malignancy in pleura fluids. Usual primary sites include the lung, breast, gastrointestinal tract, and genitourinary tracts. Predicting the site of origin of an adenocarcinoma can be difficult due to overlapping morphologic characteristics. We investigated the use of alkaline phosphatase (AP, Cytokeratin7 (CK7 Cytokeratin8 (CK8 to distinguish adenocarcinomas of lung in 148 body cavity fluid samples. Overall results for primary lung adenocarcinomas, demonstrated CK8 reactivity in 106 (72% of 148 cases. 95 primary lung carcinoma samples (65% were positive for CK7. AP was expressed in 81% of primary lung adenocarcinomas. Positive immunoreactivity for AP was characterized by a red, diffusely apical cytoplasmic staining in tumor cells that ocurred singly or in groups. There was a significant difference between AP, CK 7 and CK 8 expressions in primary lung adenocarcinomas (P=0.02; Chi-squared test. The sensitivity of AP, CK8, CK7 as a marker for primary lung adenocarcinomas were 82%, 72%, 64%, respectively. Thus the AP positive staining largely confirmed the cytologic diagnosis of lung adenocarcinoma.

  10. Primary enteric-type adenocarcinomas of the urinary bladder are histogenetically analogous to colorectal carcinomas: Immunohistochemical evaluation of 109 cases

    Saad S. Eissa

    2010-04-01

    In conclusion, primary non-urachal enteric-type adenocarcinoma of the urinary bladder is morphologically and immunophenotypically similar – if not identical – to colonic adenocarcinoma. The frequent association of enteric carcinomas of the urinary bladder with intestinal metaplasia and/or colonic-type adenomas with dysplasia suggests possible carcinogenetic pathways similar to that observed in colorectal carcinomas.

    AIM: To determine if TSPAN1 overexpression is associated with clinicopathological and prognostic factors in human colorectal adenocarcinoma. METHODS: Total RNA was extracted in 20 human adenocarcinoma tissues for TSPAN1 mRNA assay by RT-PCR. Eighty-eight specimens of human colorectal adenocarcinoma were surgically removed. TSPAN1 protein levels in cancer tissues were determined by immunohistochemistry using a polyclonal antibody against self-prepared TSPAN1. The correlation between TSPAN1 expression and the clinicopathological factors and the overall survival rate was analyzed by univariate and multivariate assay. RESULTS: TSPAN1 mRNA was detected in 90.0% (18/20) of cancerous tissues. The light density of TSPAN1 mRNA expression levels was 0.89 ± 0.30 in adenocarcinoma by gel-image system. TSPAN1 protein expression was detected in 78.41% (69/88) and weakly expressed in 40% normal colorectal tissues. There were significant differences between colorectal adenocarcinoma and normal control epithelium ( P < 0.05). TSPAN1 protein expression in colorectal cancerous tissue was significantly correlated with the histological grade, cell expression PCNA, lymph nodal metastasis and TNM staging of the disease. Patients with TSPAN1 protein overexpression had a significantly shorter survival period than that in patients with TSPAN1 protein negative or weak expression, respectively ( P < 0.05). Furthermore, by multivariate analysis, TSPAN1 protein expression demonstrated an independent prognostic factor for human colorectal cancers ( P < 0.05, relative risk 0.755; 95% confidence interval 0.302-1.208). CONCLUSION: The expression of TSPAN1 gene is increased in colorectal carcinoma, suggesting that TSPAN1 might serve as an independent prognostic factor for the colorectal adenocarcinoma patients.

  12. Concomitant mucin-producing tumors of ovary and adenocarcinoma of cervix: a case report

    Mousavi A

    2013-05-01

    Full Text Available Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma. In patients with mucinous adenocarcinoma in the abdominal cavity, caution should be exercised in interpreting the possible primary site of the tumor on the basis of the immunohistochemical profiles. The presence of human papillomavirus (HPV DNA is assessed to determine whether the ovarian neoplasms were metastases or primary independent neoplasm. Approximately 90% of endocervical adenocarcinomas are related to high-risk human papillomavirus (hr-HPV with the remainder being unrelated to HPV. Both types metastasize to the ovaries very infrequently. Ovarian endocervical-type (mullerian mucinous tumors and tumors composed of a mixture of endocervical-type mucinous, serous endometrioid, squamous, and indifferent cells with abundant eosinophilic cytoplasm reported to date have been primarily limited to borderline and micro invasive types. We report a-36-yr old woman with adenocarcinomas of uterine cervix who also had ovarian mucinous borderline tumor.Case presentation: The patient presented with abnormal uterine bleeding and lower abdominal pain. She had a history of uterine cervix polyps. Pelvic ultrasound showed a right adnexal mass and a large cervical size. Histological diagnosis in uterine cervix biopsy revealed adenocarcinoma of cervix. Radical hysterectomy type III with bilateral salpingo-oophorectomy was performed. Histological finding in adnexal mass revealed borderline mucinous tissue of ovarian tumor. Testing for HPV DNA in the tumoral tissue was negative. This confirms that the ovarian tumor is not metastatic from endocervical adenocarcinoma. Conclusion: We conclude that in a patient with

    Development from chronic inflammation to Barrett's adenocarcinoma is known as one of the inflammation-related carcinogenesis routes. Gastroesophageal reflux disease induces regurgitant esophagitis, and esophageal mucosa is usually regenerated by squamous epithelium, but sometimes and somewhere replaced with metaplastic columnar epithelium. Specialized columnar epithelium, so-called Barrett's epithelium (BE), is a risk factor for dysplasia and adenocarcinoma in esophagus. Several experiments using rodent model inducing duodenogastroesophageal reflux or duodenoesophageal reflux revealed that columnar epithelium, first emerging at the proliferative zone, progresses to dysplasia and finally adenocarcinoma, and exogenous carcinogen is not necessary for cancer development. It is demonstrated that duodenal juice rather than gastric juice is essential to develop esophageal adenocarcinoma in not only rodent experiments, but also clinical studies. Antireflux surgery and chemoprevention by proton pump inhibitors, nonsteroidal anti-inflammatory drugs, selective cyclooxygenase-2 inhibitors, green tea, retinoic acid and thioproline showed preventive effects on the development of Barrett's adenocarcinoma in rodent models, but it remains controversial whether antireflux surgery could regress BE and prevent esophageal cancer in clinical observation. The Chemoprevention for Barrett's Esophagus Trial (CBET), a phase IIb, multicenter, randomized, double-masked study using celecoxib in patients with Barrett's dysplasia failed to prove to prevent progression of dysplasia to cancer. The AspECT (Aspirin Esomeprazole Chemoprevention Trial), a large multicenter phase III randomized trial to evaluate the effects of esomeprazole and/or aspirin on the rate of progression to high-grade dysplasia or adenocarcinoma in patients with BE is now ongoing.

    BACKGROUND: Most of the reports on the prognostic indi-cators of patients with pancreatic adenocarcinoma are from developed countries. The present study focused on the prog-nostic indicators of Chinese patients with pancreatic adeno-carcinoma. METHODS: A total of 300 patients with pancreatic adenocar-cinoma who had undergone curative resection were included. The resection and R0/R1 resection rates for adenocarcinomas from different parts of the pancreas were calculated and clini-cal characteristics were analyzed. RESULTS: In 3427 patients diagnosed with pancreatic adeno-carcinomas, only 300 (8.8%) were eligible for radical resection. The total median survival of these patients was 19 months, and their 1-, 3-, and 5-year survival rates were 72.5%, 28.0%and 23.4%, respectively. The prognostic factors included so-cioeconomic status, smoking history, symptoms, high blood glucose, and various tumor characteristics, including perineu-ral and vascular invasion, lymph node metastases, and CA19-9 levels before and after operation. Operation-associated prog-nostic indicators included operation time, blood loss and transfusions, pancreatic ifstula, and complications. Indepen-dent predictors of mortality included poor socioeconomic sta-tus, smoking history, symptoms, CA19-9, perineural invasion and lymph node metastasis, grade of ifstula and complications. Patient survival was not correlated with either resection mar-gin or adjuvant chemotherapy in multivariate analysis. CONCLUSIONS: The survival rates of patients with curative resection for pancreatic adenocarcinoma in China are close to those in developed countries, but curative resection rate is far below. Socioeconomic status, symptoms, and CA19-9 are the three most prominent prognostic factors, which are helpful in patient selection and perioperative care.

  15. MRI differentiation of pneumonia-like mucinous adenocarcinoma and infectious pneumonia

    Objective: To evaluate the role of MRI water-sensitive sequences in the differential diagnosis between pneumonia-like mucinous adenocarcinoma and infectious pneumonia. Subjects and methods: Twenty-three patients with pneumonia-like mucinous adenocarcinoma and 30 patients with infectious pneumonia underwent computed tomography (CT) and MRI. Two blinded and independent readers evaluated CT and MR images using a 3-level confidence scale in two separate sessions. Results were tested for statistical significance using the Fisher's exact test and the Cohen's k test. Results: On CT, the two readers respectively made correct diagnoses of mucinous adenocarcinoma in 17 out of 23 cases (73.9%), and in 15 out of 23 cases (65.2%). A correct diagnosis of infectious pneumonia was made in 22 out of 30 cases (73.3%), and in 24 out of 30 cases (80.0%). On MRI, both readers made correct diagnoses of mucinous adenocarcinoma in 23 out of 23 (100%) cases, and of infectious pneumonia in 30 out of 30 (100%) cases. Fisher's exact test showed a significant difference in the diagnosis of mucinous adenocarcinoma between MRI and CT for both readers, P = 0.01 for reader 1 and P = 0.002 for reader 2, respectively. A good agreement (k = 0.73) was found between the two readers on CT evaluation, whereas an almost perfect agreement (k = 1.00) was found for MRI. Conclusions: MRI with “water-sensitive” sequences should be added in the diagnostic protocol of every patient with pulmonary consolidation suspected to be mucinous adenocarcinoma.

  16. Is lymphadenectomy a prognostic marker in endometrioid adenocarcinoma of the human endometrium?

    During surgery for endometrial cancer, a pelvic lymphadenectomy with or without para-aortic lymphadenectomy is performed at least in patients with risk factors (stage I, grading 2 and/or histological subtypes with higher risk of lymphatic spread), and is hence recommended by the International Federation of Obstetrics and Gynecology (FIGO). Although lymph node metastases are important prognostic parameters, it has been contentious whether a pelvic lymph node dissection itself has a prognostic impact in the treatment of endometrial cancer, especially in endometrioid adenocarcinoma. Therefore, this study evaluated whether lymphadenectomy has a prognostic impact in patients with endometrioid adenocarcinoma. The benefits of lymphadenectomy were examined in 214 patients with a histological diagnosis of endometrial adenocarcinoma. Tumour characteristics were analysed with respect to the surgical and pathological stage. Of the 214 patients with endometrial adenocarcinoma, 171 (79.9%) were classified as FIGO stage I, 15 (7.0%) FIGO stage II, 21 (9.8%) FIGO stage III and 7 (3.3%) FIGO stage IV. One hundred and thirty four (62.6%) of the patients had a histological grade 1 tumour, while 56 (26.2%) and 24 (11.2%) had a histological grade 2 or grade 3 tumour, respectively. Lymphadenectomy was performed in 151 (70.6%) patients. Only 11 (5.1%) patients showed metastatic disease in the lymph nodes. The performance of a lymphadenectomy resulted in significantly increased cause-specific and overall survival, while progression-free survival was not affected by this operative procedure. The performance of an operative lymphadenectomy resulted in better survival of patients with endometrioid adenocarcinoma. This increase was significant for cause-specific and overall survival, while there was a tendency only towards increased progression-free survival. Therefore, even in endometrioid adenocarcinoma, a pelvic and/or para-aortic lymphadenectomy should be performed

  19. Potential Role of the Microbiome in Barrett's Esophagus and Esophageal Adenocarcinoma.

    Snider, Erik J; Freedberg, Daniel E; Abrams, Julian A

    2016-08-01

    Esophageal adenocarcinoma and its precursor Barrett's esophagus have been rapidly increasing in incidence for half a century, for reasons not adequately explained by currently identified risk factors such as gastroesophageal reflux disease and obesity. The upper gastrointestinal microbiome may represent another potential cofactor. The distal esophagus has a distinct microbiome of predominantly oral-derived flora, which is altered in Barrett's esophagus and reflux esophagitis. Chronic low-grade inflammation or direct carcinogenesis from this altered microbiome may combine with known risk factors to promote Barrett's metaplasia and progression to adenocarcinoma.

    An adenocarcinoma arising from mature teratoma is one form of teratoma with malignant transformation. It is extremely rare but highly malignant. The authors report two patients with adenocarcinomas arising from primary retroperitoneal teratomas. The CT and MRI findings of the tumors are presented with emphasis on imaging features implying the presence of malignant transformation and differing from those of pure benign mature teratoma. Correct diagnosis of the presence of malignant transformation from a benign mature teratoma can be made as early as possible by awareness of the imaging features. (orig.)

  3. Synchronous association of rectal adenocarcinoma and three ileal carcinoids: a case report.

    McHugh, Seamus M

    2012-02-01

    BACKGROUND: Synchronous midgut carcinoids with gastrointestinal adenocarcinoma are a rare but recognised association. CASE PRESENTATION: The patient, a 74 year old woman, underwent anterior resection for a low rectal adenocarcinoma. Intra-operatively 3 serosal deposits of tumour were noted in the distal ileum. Histology revealed these to be ileal carcinoids. CONCLUSION: During resection of a gastrointestinal tumour, a thorough inspection of the abdominal cavity should be undertaken to investigate the possibility of metastatic secondaries or a synchronous tumour as is reported in this case.

    Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer-related deaths in the United States, and is projected to be second by 2025. It has the worst survival rate among all major cancers. Two pressing needs for extending life expectancy of affected individuals are the development of new approaches to identify improved therapeutics, addressed herein, and the identification of early markers. PDA advances through a complex series of intercellular and physiological interactions that drive cancer progression in response to organ stress, organ failure, malnutrition, and infiltrating immune and stromal cells. Candidate drugs identified in organ culture or cell-based screens must be validated in preclinical models such as KIC (p48(Cre);LSL-Kras(G12D);Cdkn2a(f/f)) mice, a genetically engineered model of PDA in which large aggressive tumors develop by 4 weeks of age. We report a rapid, systematic and robust in vivo screen for effective drug combinations to treat Kras-dependent PDA. Kras mutations occur early in tumor progression in over 90% of human PDA cases. Protein kinase and G-protein coupled receptor (GPCR) signaling activates Kras. Regulators of G-protein signaling (RGS) proteins are coincidence detectors that can be induced by multiple inputs to feedback-regulate GPCR signaling. We crossed Rgs16::GFP bacterial artificial chromosome (BAC) transgenic mice with KIC mice and show that the Rgs16::GFP transgene is a Kras(G12D)-dependent marker of all stages of PDA, and increases proportionally to tumor burden in KIC mice. RNA sequencing (RNA-Seq) analysis of cultured primary PDA cells reveals characteristics of embryonic progenitors of pancreatic ducts and endocrine cells, and extraordinarily high expression of the receptor tyrosine kinase Axl, an emerging cancer drug target. In proof-of-principle drug screens, we find that weanling KIC mice with PDA treated for 2 weeks with gemcitabine (with or without Abraxane) plus inhibitors of Axl signaling

    Full Text Available Background: There is a variable pattern of occurrence of gastric carcinomas world-wide, partially reflecting the frequency of various changes of gastric mucosa from, which such neoplasm occur. Many cases of gastric carcinoma originate in the background of chronic gastritis caused by Helicobacter pylori. Subsequent intestinal metaplasia (IM can be morphologically classified by routine and special histopathological stains. Materials and Methods: The present study was conducted over the 2 years at NRSMC & H, Kolkata. Aims of the present study were to search for evidences of H. pylori infection, classification of different metaplastic and/or malignant changes, identification of types of mucin by mucin histochemistry and their interrelationship in gastrectomy and gastric biopsy specimens (total 70. After obtaining clinical history, radiological and endoscopic findings were noted. After macroscopic study of the specimen, hematoxylene and eosin, southgate mucicarmine, periodic acid schiff-alcian blue (PAS-AB and gomori aldehyde fuchsin (GAF/AB staining were performed to classify gastric carcinoma and metaplastic changes and to correlate with staining patterns of mucin. Results: The overall male to female ratio was 2.89:1. Age ranged from 22 years to 78 years and the commonest age group of gastric carcinomas being 41-50 years (26 cases, 37.1%.

    AIM: Obesity has been proved as one of the main risk factors for gastric cardia adenocarcinoma (GCA) in the West.The objective of our research was to evaluate the relationship between obesity and the risk of GCA in people from North China.METHODS: A total of 300 patients who had been diagnosed as GCA and had accepted surgical operation at Beijing Cancer Hospital from 1995 to 2002 were enrolled. Data were collected from pathology materials and hospital records. Two hundred and fifty-eight healthy people who had accepted health examination at the same hospital during the same period were enrolled as controls. Height, weight and gender of them at the time of examination were also collected.Obesity was estimated by body mass index (BMI), computed as weight in kilograms per square surface area (Kg/m2).The degree of obesity was determined by using BMI≤ 18.5,24-27.9 and ≥28 (Kg/m2) as the cut-off points for underweight/normal, overweight and obesity, respectively.Associations with obesity were estimated by odds ratios (ORs) and 95 % confidence intervals (CIs). All ORs were adjusted for age and sex.RESULTS: The mean level of BMI was significantly lower in the patient group than that in the control group. The ORs for obesity in age groups 30-59 and 60-79 were 1.15 (95 %CI=0.37-3.65) and 0.16 (95 % CI=0.05-0.44) for males and 0.78 (95 % CI=0.26-2.36) and 0.28 (95 % CI=0.04-2.05)for females, respectively. The ORs for underweight were 2.42 (95 % CI=0.56-10.53) and 4.68 (95 % CI=1.13-19.40)for males in age subgroups 30-59 and 60-79 and 40.7 (95 %CI=9.32-177.92) for females older than 60 yrs. BMI was significantly associated with GCA (P<0.01). Underweight people were at high risk for GCA.CONCLUSION: BMI is an independent risk factor for GCA.Underweight is positively associated with GCA.

    Serous adenocarcinoma of the cervix (SACC) is a very rare tumor. Our study aimed to characterize the immune profile and human papillomavirus (HPV) status of SACC, in comparison with other serous adenocarcinomas arising in the female genital tract. The pathological specimens obtained from 81 patients with serous carcinoma of the uterine cervix (n = 12), 29 endometrium, 20 ovary and 20 patients with mucinous carcinoma of the uterine cervix were reviewed. We assessed the expression of WT-1, p53, p16, HER2, CEA, and CA125 by immunohistochemistry and HPV DNA by PCR in 12 SACC samples. Their immune profile was compared with that of uterine papillary serous carcinoma (UPSC), ovarian serous adenocarcinoma (OSA), and mucinous endocervical adenocarcinoma (MEA). WT-1 and HER2 were expressed in very few SACC samples (0 and 0%, respectively), but p16, CA125, CEA and p53 were present in 100, 92, 58 and 50%, respectively. The difference in WT-1 expression between SACC and UPSC, MEA is not significant, but SACC differ significantly from OSA (p UPSC, whereas the frequency of expression of WT-1 was significantly lower in SACC than OSA. It appeared that p53 expression was associated with worse clinical outcome in patients with SACC, and that HPV infection was related to its occurrence. PMID:25370301

  12. The Role of DNA Methylation in the Development and Progression of Lung Adenocarcinoma

    Keith M. Kerr

    2007-01-01

    Full Text Available Lung cancer, caused by smoking in ∼87% of cases, is the leading cause of cancer death in the United States and Western Europe. Adenocarcinoma is now the most common type of lung cancer in men and women in the United States, and the histological subtype most frequently seen in never-smokers and former smokers. The increasing frequency of adenocarcinoma, which occurs more peripherally in the lung, is thought to be at least partially related to modifications in cigarette manufacturing that have led to a change in the depth of smoke inhalation. The rising incidence of lung adenocarcinoma and its lethal nature underline the importance of understanding the development and progression of this disease. Alterations in DNA methylation are recognized as key epigenetic changes in cancer, contributing to chromosomal instability through global hypomethylation, and aberrant gene expression through alterations in the methylation levels at promoter CpG islands. The identification of sequential changes in DNA methylation during progression and metastasis of lung adenocarcinoma, and the elucidation of their interplay with genetic changes, will broaden our molecular understanding of this disease, providing insights that may be applicable to the development of targeted drugs, as well as powerful markers for early detection and patient classification.

    Long-term outcome data in pancreatic adenocarcinoma are predominantly based on surgical series, as resection is currently considered essential for long-term survival. In contrast, five-year survival in non-resected patients has rarely been reported. In this report, we examined the incidence and natural history of ≥ 5-year survivors with non-resected pancreatic adenocarcinoma. All patients with pancreatic adenocarcinoma who received oncologic therapy alone without surgery at our institution between 1995 and 2009 were identified. Non-resected ≥ 5-year survivors represented 2% (11/544) of all non-resected patients undergoing treatment for pancreatic adenocarcinoma, and 11% (11/98) of ≥ 5-year survivors. Nine patients had localized tumor and 2 metastatic disease at initial diagnosis. Disease progression occurred in 6 patients, and the local tumor bed was the most common site of progression. Six patients suffered from significant morbidities including recurrent cholangitis, second malignancy, malnutrition and bowel perforation. A rare subset of patients with pancreatic cancer achieve long-term survival without resection. Despite prolonged survival, morbidities unrelated to the primary cancer were frequently encountered and a close follow-up is warranted in these patients. Factors such as tumor biology and host immunity may play a key role in disease progression and survival. PMID:26730170

  15. Genetic mutation analysis of human gastric adenocarcinomas using ion torrent sequencing platform.

    Zhi Xu

    Full Text Available Gastric cancer is the one of the major causes of cancer-related death, especially in Asia. Gastric adenocarcinoma, the most common type of gastric cancer, is heterogeneous and its incidence and cause varies widely with geographical regions, gender, ethnicity, and diet. Since unique mutations have been observed in individual human cancer samples, identification and characterization of the molecular alterations underlying individual gastric adenocarcinomas is a critical step for developing more effective, personalized therapies. Until recently, identifying genetic mutations on an individual basis by DNA sequencing remained a daunting task. Recent advances in new next-generation DNA sequencing technologies, such as the semiconductor-based Ion Torrent sequencing platform, makes DNA sequencing cheaper, faster, and more reliable. In this study, we aim to identify genetic mutations in the genes which are targeted by drugs in clinical use or are under development in individual human gastric adenocarcinoma samples using Ion Torrent sequencing. We sequenced 737 loci from 45 cancer-related genes in 238 human gastric adenocarcinoma samples using the Ion Torrent Ampliseq Cancer Panel. The sequencing analysis revealed a high occurrence of mutations along the TP53 locus (9.7% in our sample set. Thus, this study indicates the utility of a cost and time efficient tool such as Ion Torrent sequencing to screen cancer mutations for the development of personalized cancer therapy.

  16. Small primary adenocarcinoma in adenomyosis with nodal metastasis: a case report

    Campagnutta Elio

    2007-06-01

    Full Text Available Abstract Background Malignant transformation of adenomyosis is a very rare event. Only about 30 cases of this occurrence have been documented till now. Case presentation The patient was a 57-year-old woman with a slightly enlarged uterus, who underwent total hysterectomy and unilateral adnexectomy. On gross inspection, the uterine wall displayed a single nodule measuring 5 cm and several small gelatinous lesions. Microscopic examination revealed a common leiomyoma and multiple adenomyotic foci. A few of these glands were transformed into a moderately differentiated adenocarcinoma. The endometrium was completely examined and tumor free. The carcinoma was, therefore, considered to be an endometrioid adenocarcinoma arising from adenomyosis. Four months later, an ultrasound scan revealed enlarged pelvic lymph nodes: a cytological diagnosis of metastatic adenocarcinoma was made. Immunohistochemical studies showed an enhanced positivity of the tumor site together with the neighbouring adenomyotic foci for estrogen receptors, aromatase, p53 and COX-2 expression when compared to the distant adenomyotic glands and the endometrium. We therefore postulate that the neoplastic transformation of adenomyosis implies an early carcinogenic event involving p53 and COX-2; further tumor growth is sustained by an autocrine-paracrine loop, based on a modulation of hormone receptors as well as aromatase and COX-2 local expression. Conclusion Adenocarcinoma in adenomyosis may be affected by local hormonal influence and, despite its small size, may metastasize.

  18. The function of SARI in modulating epithelial-mesenchymal transition and lung adenocarcinoma metastasis.

    Changli Wang

    Full Text Available The SARI (suppressor of AP-1, regulated by IFN gene, which is also called BATF2, is associated with the risk of several kinds of cancer, and loss of SARI expression is frequently detected in aggressive and metastatic cancer. However, the functional role of SARI in lung adenocarcinoma remains unknown. We have shown that loss of SARI expression initiates epithelial-mesenchymal transition (EMT, which is visualized by repression of E-cadherin and up-regulation of vimentin in lung adenocarcinoma cell lines and in clinical lung adenocarcinoma specimens. Using a human lung xenograft-mouse model, we observed that knocking down endogenous SARI in human carcinoma cells leads to the development of multiple lymph node metastases. Moreover, we showed that SARI functions as a critical protein in regulating EMT by modulating the (GSK-3β-β-catenin signaling pathway. These results demonstrate the mechanism of SARI function in EMT and suggest that assessment of SARI may serve as a prognostic biomarker and potential therapeutic target for lung adenocarcinoma metastasis.

    2014-04-01

    Primary seminal vesicle (SV) adenocarcinoma is a rare tumor. A small amount of data about the role of imaging to detect tumor recurrence is available. We report the case of a 58-year-old patient with primary SV clear-cell well-differentiated adenocarcinoma. Clinical and instrumental examinations were negative for the 32 months after treatments when computed tomography scan, [(18)F]fluoro-D-glucose positron emission tomography/computed tomography and pelvic magnetic resonance imaging showed the appearance of a lesion in the left perineal muscle suspected for recurrence. Patient was symptomless. Cytology of the suspected lesion confirmed SV adenocarcinoma recurrence. The combined approach, using radiological and nuclear medicine techniques, seems to be effective in the follow-up of SV adenocarcinoma. Technological advances, together with awareness of this rare tumor, have the potential of improving patients outcomes not only by providing earlier detection and accurate staging, but also by detecting recurrence and thereby avoiding delays and therapeutic dilemmas.

  20. Natural history of adenocarcinoma of the lung. A computed tomography-pathologic correlative study

    To determine the natural history of adenocarcinoma of the lung, we reviewed computed tomography (CT) scans for nine patients with histologically proven peripheral adenocarcinoma of the lung. The tumors on these CT images were correlated with the six histologic classifications (types A-F) reported by Noguchi et al. The findings for all adenocarcinomas on the CT images were classified into two patterns: the solid-density type (n=5) or the air-containing type (n=4). Among those the air-containing category, types A and B were revealed in one and three cases, respectively. Those in the solid-density category were all type C, except for two cases which were type D. Three of the tumors of the solid-density type appearing in the CT images, which tended to fall mainly into type C, exhibited a progression from the air-containing type to the solid-density type. We speculate that this progression observed in the CT images suggests that pulmonary small adenocarcinoma follows a pattern of development from the types A and B to the invasive type C. (author)

    2015-01-01

    Primary adenocarcinoma of the small intestine occurs in over 50% of cases in the duodenum. However, its location in the third and fourth duodenal portions occurs rarely and is a diagnostic challenge. The aim of this work is to report an adenocarcinoma of the third and fourth duodenal portions, emphasizing its diagnostic difficulty and the value of video capsule endoscopy. A man, 40 years old, with no medical history, with abdominal discomfort and progressive fatigue, presented four months ago with one episode of moderate melena. The physical examination was normal, except for mucosal pallor. Blood tests were consistent with microcytic, hypochromic iron deficiency anemia with 7.8 g/dL hemoglobin. The upper and lower endoscopy were normal. Additional work-up with video capsule endoscopy showed a polypoid lesion involving the third and fourth portions of the duodenum. Biopsy showed a moderately differentiated adenocarcinoma. Abdominal computed tomography showed a wall thickening from the third duodenal portion to the proximal jejunum, without distant metastasis. The patient underwent segmental resection (distal duodenum and proximal jejunum) with duodenojejunostomy. The surgical specimen histology confirmed the biopsy diagnosis, with transmural infiltration, without nodal involvement. Conclusion: Adenocarcinoma of the third and fourth portions of the duodenum is difficult to diagnose and capsule endoscopy is of great value. PMID:26309371

  6. Rb and p53 gene deletions in lung adenocarcinomas from irradiated and control mice

    This study was conducted on mouse lung adenocarcinoma tissues that were formalin-treated and paraffin-embedded 25 years ago to investigate the large gene deletions of mRb and p53 in B6CF1 male mice. A total of 80 lung tissue samples from irradiated mice and 40 lung samples from nonirradiated controls were randomly selected and examined in the mRb portion of this study. The results showed a significant (P 0.05) from that for spontaneous lung adenocarcinomas or lung adenocarcinomas from mice exposed to single-dose γ irradiation at a similar total dose. mRb fragments 3 (71%) and 5 (67%), the parts of the gene that encoded the pocket binding region of Rb protein to adenovirus E1A and SV40 T-antigen, were the most frequently deleted fragments. p53 gene deletion analysis was carried out on normal lungs and lung adenocarcinomas that were initially found to bear mRb deletions. Exons 1,4,5,6, and 9 were chosen to be analyzed

  10. Second Primary Pancreatic Adenocarcinoma Three Years After Successfully Treated Index Esophageal Cancer

    Nina Nandy

    2014-01-01

    Full Text Available Context Development of a second primary malignancy after an index esophageal cancer is a rare event, primarily due to short survival of patients with esophageal cancer. However, the number of long-term esophageal cancer survivors has been increasing due to advances in early detection and therapy. Case report We report herein a case of pancreatic adenocarcinoma that developed three years after a successfully treated early-stage adenocarcinoma of the esophagus. A 70-year-old Caucasian male presented with vague complaints of nausea, vomiting and abdominal distention, with subsequent development of jaundice. A computed tomography scan of abdomen revealed a 2.9 cm soft tissue mass in the head of the pancreas and the patient underwent a Whipple’s procedure, with pathology confirming the diagnosis of pancreatic adenocarcinoma. Three years previously, the patient was successfully treated for adenocarcinoma of the esophagus via minimally invasive esophagogastrectomy. Despite chemoradiotherapy for localized disease and subsequent systemic chemotherapy for metastatic pancreatic cancer, the patient eventually succumbed to his illness. Conclusion We discuss the association between esophageal cancer and subsequent second malignancies, along with implications for surveillance and therapy.

  11. Polymorphous low-grade adenocarcinoma of the nasopharynx. Case report and review of the literature

    Background: The polymorphous low-grade adenocarcinoma of the nasopharynx is a rare disease. Polymorphous low-grade adenocarcinoma is a minor salivary gland neoplasm which occurs frequently in the mucosa of the soft and hard palates, in the buccal mucosa and in the upper lip. To date this entity has been identified within the oral cavity and only one case within the nasopharynx and some cases in the parotid gland. It has a slow infiltrating growing pattern with frequent perineural invasion and low metastatic potential. Case Report: We report on a patient with non-papillary polymorphous low-grade adenocarcinoma in the nasopharynx which extended intracranially. The patient underwent primary radiotherapy. The CT showed partial response to radiotherapy and the patient is alive 51 months after the diagnosis his state being unchanged. Conclusion: The treatment for minor salivary gland tumor is primarily surgical. It is reported that the polymorphous low-grade adenocarcinoma has been known to have poor response to radiotherapy. However, we believe that in addition to its favorable biological behavior, the radiotherapy in this localization may result in longer survival. (orig.)

    2016-08-01

    A 67-year-old woman was admitted to our hospital for further examination and for treatment of gastric neoplasia located on the posterior wall of the antrum of the stomach, as revealed by screening esophagogastroduodenoscopy. The patient had no history of Helicobacter pylori (H. pylori) eradication. Her serum H. pylori antibody and urea breath test results were negative, histopathological findings revealed no H. pylori bacteria, and endoscopic findings revealed no chronic gastritis. We performed endoscopic submucosal dissection (ESD). Histological examination of the resected tissues revealed the tumor to be composed of a well-differentiated tubular adenocarcinoma with a tubular-type adenoma confined to the mucosa. This adenocarcinoma exhibited immunohistochemical expression of CD10, MUC2, and Cdx2, but not MUC5AC or MUC6. This is an extremely rare case of H. pylori infection-negative, intestinal-type, differentiated gastric adenocarcinoma revealed by detailed immunohistochemical examination that was treated with ESD. The patient has had no recurrence of adenocarcinoma after ESD. PMID:27259702

  13. Proteomic Analysis of Cytokeratin Isoforms Uncovers Association with Survival in Lung Adenocarcinoma

    Tarek G. Gharib

    2002-01-01

    Full Text Available Cytokeratins. (CK are intermediate filaments whose expression is often altered in epithelial cancer. Systematic identification of lung adenocarcinoma proteins using two-dimensional polyacrylamide gel electrophoresis and mass spectrometry has uncovered numerous CK isoforms. In this study, 93 lung adenocarcinomas. (64 stage I and 29 stage III and 10 uninvolved lung samples were quantitatively examined for protein expression. Fourteen of 21 isoforms of CK 7, 8, 18, 19 occurred at significantly higher levels. (P<.05 in tumors compared to uninvolved adjacent tissue. Specific isoforms of the four types of CK identified correlated with either clinical outcome or individual clinical-pathological parameters. All five of the CK7 isoforms associated with patient survival represented cleavage products. Two of five CK7 isoforms. (nos. 2165 and 2091, one of eight CK8 isoforms. (no. 439, one of three CK19 isoforms. (no. 1955 were associated with survival and significantly correlated to their mRNA levels, suggesting that transcription underlies overexpression of these CK isoforms. Our data indicate substantial heterogeneity among CK in lung adenocarcinomas resulting from posttranslational modifications, some of which correlated with patient survival and other clinical parameters. Therefore, specific isoforms of individual CK may have utility as diagnostic or predictive markers in lung adenocarcinomas.

    Mathieu Salaün

    Full Text Available Several matrix metalloproteinases (MMPs are overexpressed in lung cancer and may serve as potential targets for the development of bioactivable probes for molecular imaging.To characterize and monitor the activity of MMPs during the progression of lung adenocarcinoma.K-rasLSL-G12D mice were imaged serially during the development of adenocarcinomas using fluorescence molecular tomography (FMT and a probe specific for MMP-2, -3, -9 and -13. Lung tumors were identified using FMT and MRI co-registration, and the probe concentration in each tumor was assessed at each time-point. The expression of Mmp2, -3, -9, -13 was quantified by qRT-PCR using RNA isolated from microdissected tumor cells. Immunohistochemical staining of overexpressed MMPs in animals was assessed on human lung tumors.In mice, 7 adenomas and 5 adenocarcinomas showed an increase in fluorescent signal on successive FMT scans, starting between weeks 4 and 8. qRT-PCR assays revealed significant overexpression of only Mmp-13 in mice lung tumors. In human tumors, a high MMP-13 immunostaining index was found in tumor cells from invasive lesions (24/27, but in none of the non-invasive (0/4 (p=0.001.MMP-13 is detected in early pulmonary invasive adenocarcinomas and may be a potential target for molecular imaging of lung cancer.

  17. Direct Liver Invasion from a Gastric Adenocarcinoma as an Initial Presentation of Extranodal Tumor Spread

    Mitanshu Shah

    2012-01-01

    Full Text Available Gastric cancer often carries a poor prognosis, with an estimated 740,000 deaths from the malignancy occurring yearly worldwide (Dicken et al., 2005. The mortality of disease is largely dependent on the extent of tumor spread, as gastric cancer has a predilection to metastasize to other visceral secondaries via hematogenous and lymphatic dissemination. Direct invasion of a gastric adenocarcinoma to adjacent organs secondary to gastric wall perforation does occur; however, it is often present in the setting of advanced disease. Rarely does direct tumor invasion to adjacent organs from a gastric adenocarcinoma present as the initial manifestation of extranodal tumor spread. We present a case of a 40-year-old male with direct tumor extension to the liver as an initial presentation of extranodal tumor spread from a gastric adenocarcinoma. Clinicians should be aware of such an occurrence, as treatment modalities in direct liver extension from a gastric adenocarcinoma vary and may be directed towards palliation rather than curative intent.

  1. Metastatic prostatic adenocarcinoma diagnosed in a bronchoalveolar lavage specimen: An unusual presentation of a common tumor

    Adrienne E Moul

    2016-01-01

    Full Text Available Metastatic prostatic adenocarcinoma presenting as a primary lung disease is rare. We present a 52-year-old male with a 3-month history of cough, shortness of breath, and weight loss with clinical and radiological findings suggestive of a primary lung disease: Bilateral interstitial and alveolar opacities with blunting of the costophrenic angles, multiple diffuse foci of consolidations and nodules, predominantly subpleural and located in the lower lobes, and diffuse interlobular septal thickening and peribronchial thickening. The patient underwent bronchoscopy and bronchoalveolar lavage (BAL was obtained. Cytospin smears were diagnostic for a low-grade adenocarcinoma. Clinically, the patient had elevated serum prostate-specific antigen (PSA levels greater than 5,000 ng/mL. Because of this, immunocytochemistry for PSA was performed which was positive, confirming the diagnosis of metastatic prostatic adenocarcinoma. This unusual case of metastatic adenocarcinoma of the prostate first diagnosed by BAL highlights the significance of available clinical information and the use of immunocytochemistry for proper diagnosis.

  3. Silenced Expression of NFKBIA in Lung Adenocarcinoma Patients with a Never-smoking History

    Furukawa,Masashi

    2013-02-01

    Full Text Available Nuclear factor of κ-light polypeptide gene enhancer in B cells inhibitor α (NFKBIA, which is a tumor suppressor gene, was found to be silenced in lung adenocarcinomas. We examined NFKBIA expression, mutations in the EGFR and K-ras genes, and EML4-ALK fusion in 101 resected lung adenocarcinoma samples from never-smokers. NFKBIA expression was evaluated using immunohistochemistry. NFKBIA expression was negative in 16 of the 101 samples (15.8%. EGFR and K-ras mutations and EML4-ALK fusion were detected in 61 (60.5%, 1 (1.0%, and 2 (2.0% of the 101 samples, respectively, in a completely mutually exclusive manner. Negative NFKBIA expression was observed significantly more frequently among the tumors with none of the three genetic alterations compared to those with such alterations (p=0.009. In addition, negative NFKBIA expression was significantly more frequent among the EGFR-wild type samples compared to the EGFR-mutant samples (p=0.013. In conclusion, NFKBIA expression was silenced in adenocarcinomas without EGFR/K-ras mutations or EML4-ALK fusion, suggesting that the silencing of NFKBIA may play an important role in the carcinogenesis of adenocarcinomas independent of EGFR/K-ras mutations or EML4-ALK fusion.

  4. Mesonephric Adenocarcinoma of the Uterine Corpus: A Case Report and Diagnostic Pitfall.

    Kim, Sung Sun; Nam, Jong Hee; Kim, Ga-Eon; Choi, Yoo Duk; Choi, Chan; Park, Chang Soo

    2016-04-01

    Mesonephric adenocarcinoma is a rare tumor type that is usually found in areas where the Wolffian duct was present during the fetal period. We report a case of mesonephric adenocarcinoma of the uterine corpus in a 66-year-old woman who presented with vaginal bleeding. Pelvic magnetic resonance imaging revealed a 2.7-cm-sized irregular thickening and enhancement of the uterine body. The diagnosis following endometrial curettage biopsy was endometrioid adenocarcinoma, and the patient underwent a total hysterectomy with bilateral salpingo-oophorectomy. The tumor was composed of small tubular and ductal components, and a retiform appearance was also observed in the deeper areas. The tumor cells were immunopositive for cytokeratin, vimentin, CD10 with a luminal staining pattern, PAX2, and PAX8, and immunonegative for estrogen receptor and progesterone receptor, which was consistent with tumor of mesonephric origin. Mesonephric neoplasms reveal relatively low-grade nuclear feature, characteristic immunoprofiles (immunonegative for ER and PR, and immunopositive for CD10, PAX2, PAX8, and GATA3), and unique tumor location (myometrium), whereas Müllerian neoplasms such as endometrial adenocarcinoma show various morphology, immunopositivity for ER and PR, and primarily endometrial location. As described above, an integration of the clinical features, morphologic characteristics, and immunohistochemical profiles is needed to make a diagnosis. PMID:26510860

  5. Aryl hydrocarbon receptor protects lung adenocarcinoma cells against cigarette sidestream smoke particulates-induced oxidative stress

    Environmental cigarette smoke has been suggested to promote lung adenocarcinoma progression through aryl hydrocarbon receptor (AhR)-signaled metabolism. However, whether AhR facilitates metabolic activation or detoxification in exposed adenocarcinoma cells remains ambiguous. To address this question, we have modified the expression level of AhR in two human lung adenocarcinoma cell lines and examined their response to an extract of cigarette sidestream smoke particulates (CSSP). We found that overexpression of AhR in the CL1-5 cell line reduced CSSP-induced ROS production and oxidative DNA damage, whereas knockdown of AhR expression increased ROS level in CSSP-exposed H1355 cells. Oxidative stress sensor Nrf2 and its target gene NQO1 were insensitive to AhR expression level and CSSP treatment in human lung adenocarcinoma cells. In contrast, induction of AhR expression concurrently increased mRNA expression of xenobiotic-metabolizing genes CYP1B1, UGT1A8, and UGT1A10 in a ligand-independent manner. It appeared that AhR accelerated xenobiotic clearing and diminished associated oxidative stress by coordinate regulation of a set of phase I and II metabolizing genes. However, the AhR-signaled protection could not shield cells from constant oxidative stress. Prolonged exposure to high concentrations of CSSP induced G0/G1 cell cycle arrest via the p53–p21–Rb1 signaling pathway. Despite no effect on DNA repair rate, AhR facilitated the recovery of cells from growth arrest when CSSP exposure ended. AhR-overexpressing lung adenocarcinoma cells exhibited an increased anchorage-dependent and independent proliferation when recovery from exposure. In summary, our data demonstrated that AhR protected lung adenocarcinoma cells against CSSP-induced oxidative stress and promoted post-exposure clonogenicity. -- Highlights: ► AhR expression level influences cigarette sidestream smoke-induced ROS production. ► AhR reduces oxidative stress by coordinate regulation of

  6. The efficacy of diffusion weighted imaging and apparent diffusion coefficients mapping for liver metastasis of colonic adenocarcinomas

    Metin, Melike R.; Aydın, Hasan; Çetin, Hüseyin; Özmen, Evrim; Kayaçetin, Serra

    2016-01-01

    Objectives: To establish retrospectively the relation between the histopathologic grade of colorectal liver metastasis and apparent diffusion coefficient (ADC) values of hepatic metastases of colorectal adenocarcinomas. Methods: The diagnoses of liver metastases were confirmed with biopsy, surgery, and follow-up imaging findings. Twenty-six patients with 94 liver metastasis were included in the study. Of 94 masses, 59 were poorly-differentiated adenocarcinoma, 18 were moderately-differentiated adenocarcinoma, and 17 were well-differentiated regarding the diameters, ADC values, and ratio index (RI) values. Kolmogorov-smirnov normality test, Kruskal-wallis analysis of variance, Mann-Whitney U test with Bonferroni correction, Spearman correlation analysis, and receiver operating characteristics curve methods were applied to evaluate the statistical relations. Results: There was a statistically significant difference in terms of ADC values and RI between poorly-differentiated adenocarcinoma and moderately-differentiated adenocarcinoma plus well-differentiated adenocarcinomas. Poorly-differentiated adenocarcinomas have the lowest ADC values and highest RI values among other groups. Conclusion: Use of ADC values alone can be executed for the diagnosis of focal hepatic masses and also can aid in the differentiation of benign and malignant hepatic lesions. PMID:27052280

  7. The ERK MAP kinase-PEA3/ETV4-MMP-1 axis is operative in oesophageal adenocarcinoma

    Keld, Richard

    2010-12-09

    Abstract Background Many members of the ETS-domain transcription factor family are important drivers of tumourigenesis. In this context, their activation by Ras-ERK pathway signaling is particularly relevant to the tumourigenic properties of many ETS-domain transcription factors. The PEA3 subfamily of ETS-domain transcription factors have been implicated in tumour metastasis in several different cancers. Results Here, we have studied the expression of the PEA3 subfamily members PEA3\\/ETV4 and ER81\\/ETV1 in oesophageal adenocarcinomas and determined their role in oesophageal adenocarcinoma cell function. PEA3 plays an important role in controlling both the proliferation and invasive properties of OE33 oesophageal adenocarcinoma cells. A key target gene is MMP-1. The ERK MAP kinase pathway activates PEA3 subfamily members and also plays a role in these PEA3 controlled events, establishing the ERK-PEA3-MMP-1 axis as important in OE33 cells. PEA3 subfamily members are upregulated in human adenocarcinomas and expression correlates with MMP-1 expression and late stage metastatic disease. Enhanced ERK signaling is also more prevalent in late stage oesophageal adenocarcinomas. Conclusions This study shows that the ERK-PEA3-MMP-1 axis is upregulated in oesophageal adenocarcinoma cells and is a potentially important driver of the metastatic progression of oesophageal adenocarcinomas.

    2008-12-01

    Full Text Available Abstract Background Coexistence of adenocarcinoma and mantle cell lymphoma in the same or different anatomical sites is extremely rare. We present a case of incidental discovery of primary lung adenocarcinoma and mantle cell lymphoma involving the pleura, during an axillary thoracotomy performed for a benign condition. Case presentation A 73-year old male underwent bullectomy and apical pleurectomy for persistent pneumothorax. A bulla of the lung apex was resected en bloc with a scar-like lesion of the lung, which was located in proximity with the bulla origin, by a wide wedge resection. Histologic examination of the stripped-off parietal pleura and of the bullectomy specimen revealed the synchronous occurrence of two distinct neoplasms, a lymphoma infiltrating the pleura and a primary, early lung adenocarcinoma. Immunohistochemical and fluorescence in situ hybridization assays were performed. The morphologic, immunophenotypic and genetic findings supported the diagnosis of primary lung adenocarcinoma (papillary subtype coexisting with a non-Hodgkin, B-cell lineage, mantle cell lymphoma involving both, visceral and parietal pleura and without mediastinal lymph node involvement. The neoplastic lymphoid cells showed the characteristic immunophenotype of mantle cell lymphoma and the translocation t(11;14. The patient received 6 cycles of chemotherapy, while pulmonary function tests precluded further pulmonary parenchyma resection (lobectomy for his adenocarcinoma. The patient is alive and without clinical and radiological findings of local recurrence or distant relapse from both tumors 14 months later. Conclusion This is the first reported case of a rare tumoral combination involving simultaneously lung and pleura, emphasizing at the incidental discovery of the two coexisting neoplasms during a procedure performed for a benign condition. Any tissue specimen resected during operations performed for non-tumoral conditions should be routinely sent for

    Circulating tumor cells (CTCs) have been implicated in cancer prognosis and follow up. Detection of CTCs was considered significant in cancer evaluation. However, due to the heterogeneity and rareness of CTCs, detecting them with a single maker is usually challenged with low specificity and sensitivity. Previous studies concerning CTCs detection in lung cancer mainly focused on non-small cell lung carcinoma. Currently, there is no report yet describing the CTC detection with multiple markers in lung adenocarcinoma. In this study, by employing quantitative real-time PCR, we identified four candidate genes (mRNA) that were significantly elevated in peripheral blood mononuclear cells and biopsy tissue samples from patients with lung adenocarcinoma: cytokeratin 7 (CK7), Ca(2+)-activated chloride channel-2 (CLCA2), hyaluronan-mediated motility receptor (HMMR), and human telomerase catalytic subunit (hTERT). Then, the four markers were used for CTC detection; namely, positive detection was defined if at least one of the four markers was elevated. The positive CTC detection rate was 74.0% in patients with lung adenocarcinoma while 2.2% for healthy controls, 6.3% for benign lung disease, and 48.0% for non-adenocarcinoma non-small cell lung carcinoma. Furthermore, in a three-year follow-up study, patients with an increase in the detection markers of CTCs (CK7, CLCA2, HMMR or hTERT) on day 90 after first detection had shorter survival time compared to those with a decrease. These results demonstrate that the combination of the four markers with specificity and sensitivity is of great value in lung adenocarcinoma prognosis and follow up. PMID:25175030

    Despite the increasing lung cancer-associated death rate, its therapy has been constrained by impasse of early diagnosis. To apply non-invasive imaging for potential cancer diagnosis system, we screened human lung adenocarcinoma-specific peptides using the phage display technique. For in vivo phage-displayed peptide screening, M13 phage library displaying 2.9 × 10(9) random peptides was injected through tail vein to lung adenocarcinoma cell-derived xenograft mouse model. Through four rounds of biopanning, a specific peptide sequence (CAKATCPAC) was screened out with the highest frequency and was named as Pep-1, and it was analyzed for its targeting ability as an imaging probe by in vitro competitive assay to test its cell-binding ability, immunohistochemical detection in the tumor tissue, and in vivo NIR fluorescent optical imaging. The specificity of Pep-1 toward lung cancer was ensured by in vivo imaging using xenograft animals of various cancer types. The results suggest that Pep-1 is a promising diagnostic lead molecule for rapid and accurate detection of human lung adenocarcinoma. In addition, it was found that the targeting ability was much enhanced by ionizing radiation in both cell-derived and patient-derived lung adenocarcinoma xenografts, suggesting the possibility of applying Pep-1 for prognostic diagnosis after radiotherapy. Taken together, this study suggests that Pep-1 possesses a specific-targeting ability for human lung adenocarcinoma and that this peptide could be directly used as a clinically applicable imaging probe.

    AIM: To evaluate the relation of cluster of differentiation 44 (CD44) expression with clinicopathological features of gastric adenocarcinoma, and also its effect on prognosis with an emphasis on the differences between intestinal and diffuse types. METHODS: From 2000 to 2006, 100 patients with gastric adenocarcinoma, who had undergone total or subtotal gastrectomy without any prior treatment, were studied. Haematoxylin & eosin (HE) staining was used for histological evaluation, including the type (Lauren's classification) and grading of the tumor. The expression of CD44 in the gastric adenocarcinoma mucosa and the adjacent mucosa were determined by immunohistochemistry. The survival analysis was obtained using the Kaplan-Meier test. RESULTS: Of 100 patients, 74 (74%) patients were male. The tumors were categorized as intestinal type (78%) or diffuse type (22%). Sixty-five percent of patients were CD44-positive. CD44 expression was not detected in normal gastric mucosa. Rather, CD44 was more commonly expressed in the intestinal subtype (P = 0.002). A significant relation was seen between the grade of tumor and the expression of CD44 (P=0.014). The survival analysis showed a poor prognosis of patients with CD44-positive tumors (P = 0.008); and this was more prominent in the intestinal (P = 0.001) rather than diffuse type. CONCLUSION: Cell adhesion molecule CD44 is highly expressed in gastric adenocarcinoma. CD44 expression is correlated with a poor prognosis in patients with the intestinal type of gastric adenocarcinoma. CD44 can, therefore, be utilized as a prognostic marker for this group of patients.

    2011-05-01

    Full Text Available Abstract Background The human coagulation trigger tissue factor (TF is overexpressed in several types of cancer and involved in tumor growth, vascularization, and metastasis. To explore the role of TF in biological processes of lung adenocarcinoma, we used RNA interference (RNAi technology to silence TF in a lung adenocarcinoma cell line A549 with high-level expression of TF and evaluate its antitumor effects in vitro and in vivo. Methods The specific small interfering RNA (siRNA designed for targeting human TF was transfected into A549 cells. The expression of TF was detected by reverse transcription-PCR and Western blot. Cell proliferation was measured by MTT and clonogenic assays. Cell apoptosis was assessed by flow cytometry. The metastatic potential of A549 cells was determined by wound healing, the mobility and Matrigel invasion assays. Expressions of PI3K/Akt, Erk1/2, VEGF and MMP-2/-9 in transfected cells were detected by Western blot. In vivo, the effect of TF-siRNA on the growth of A549 lung adenocarcinoma xenografts in nude mice was investigated. Results TF -siRNA significantly reduced the expression of TF in the mRNA and protein levels. The down-regulation of TF in A549 cells resulted in the suppression of cell proliferation, invasion and metastasis and induced cell apoptosis in dose-dependent manner. Erk MAPK, PI3K/Akt pathways as well as VEGF and MMP-2/-9 expressions were inhibited in TF-siRNA transfected cells. Moreover, intratumoral injection of siRNA targeting TF suppressed the tumor growth of A549 cells in vivo model of lung adenocarcinoma. Conclusions Down-regulation of TF using siRNA could provide a potential approach for gene therapy against lung adenocarcinoma, and the antitumor effects may be associated with inhibition of Erk MAPK, PI3K/Akt pathways.

  14. Pancreatobiliary versus intestinal histologic type of differentiation is an independent prognostic factor in resected periampullary adenocarcinoma

    Cvancarova Milada

    2008-06-01

    Full Text Available Abstract Background Resectable adenocarcinomas in the pancreatic head, by definition "periampullary", originate from ampullary, duodenal, biliary, or ductal pancreatic epithelium. Typically, periampullary adenocarcinomas have either intestinal or pancreatobiliary type of differentiation, and the type of differentiation might be prognostically more important than the anatomic site of origin. The aim of the study was to determine whether the histologic type of differentiation is an independent prognostic factor in periampullary adenocarcinoma, and whether tumour origin predicts the prognosis in pancreatobiliary type carcinomas independently of resection margin involvement, tumour size, nodal involvement, perineural and vascular infiltration, and degree of differentiation. Methods Histopathologic variables in 114 consecutively resected periampullary adenocarcinomas of pancreatobiliary (n = 67 and intestinal (n = 47 type differentiation were evaluated using a standardized, systematic protocol for evaluation of the resected specimen (study group. Histologic type of differentiation and tumour origin were compared as predictors of survival, and the results were validated by comparison with a historical control group consisting of 99 consecutive pancreaticoduodenectomies performed before standardization of histopathologic evaluation. Associations between histopathologic variables were evaluated by Chi-square and Mann-Whitney tests. Survival was estimated by the Kaplan-Meier method, comparing curves using log-rank test, and by univariate and multivariable Cox regression analysis. Results Both in the study group (n = 114 and in the historical control group (n = 99, the histologic type of differentiation independently predicted survival, while tumour origin predicted survival only in univariate analysis. Independent adverse predictors of survival in the study group were pancreatobiliary type differentiation (p Conclusion Pancreatobiliary versus intestinal

  15. NR4A2 is regulated by gastrin and influences cellular responses of gastric adenocarcinoma cells.

    Kristine Misund

    Full Text Available The peptide hormone gastrin is known to play a role in differentiation, growth and apoptosis of cells in the gastric mucosa. In this study we demonstrate that gastrin induces Nuclear Receptor 4A2 (NR4A2 expression in the adenocarcinoma cell lines AR42J and AGS-GR, which both possess the gastrin/CCK2 receptor. In vivo, NR4A2 is strongly expressed in the gastrin responsive neuroendocrine ECL cells in normal mucosa, whereas gastric adenocarcinoma tissue reveals a more diffuse and variable expression in tumor cells. We show that NR4A2 is a primary early transient gastrin induced gene in adenocarcinoma cell lines, and that NR4A2 expression is negatively regulated by inducible cAMP early repressor (ICER and zinc finger protein 36, C3H1 type-like 1 (Zfp36l1, suggesting that these gastrin regulated proteins exert a negative feedback control of NR4A2 activated responses. FRAP analyses indicate that gastrin also modifies the nucleus-cytosol shuttling of NR4A2, with more NR4A2 localized to cytoplasm upon gastrin treatment. Knock-down experiments with siRNA targeting NR4A2 increase migration of gastrin treated adenocarcinoma AGS-GR cells, while ectopically expressed NR4A2 increases apoptosis and hampers gastrin induced invasion, indicating a tumor suppressor function of NR4A2. Collectively, our results uncover a role of NR4A2 in gastric adenocarcinoma cells, and suggest that both the level and the localization of NR4A2 protein are of importance regarding the cellular responses of these cells.

A sobrevida global média foi de 25,5 meses (3 a 105 meses, e quando separada em estádios, foi 53,3 meses até estádio IIa e 15,8 meses em estado IIb ou superior. CONCLUSÃO: A cirurgia minimamente invasiva pode ser alternativa no tratamento do adenocarcinoma da transição esofagogástrica.BACKGROUND: In the last decades an overwhelming increase in the incidence of esophagogastric transition adenocarcinomas has been observed. Jointly to this increase, there has also been progress in minimal invasive surgery. AIM: To relate the experience with video-assisted esophagectomy, transhiatal for the treatment of esophagogastric transition adenocarcinoma. METHODS: The technique was indicated to 30 patients, predominantly male (73% with an average age of 55 years. After laparoscopic evaluation, 19 patients were operated on using the video-assisted technique. RESULTS: Surgical time varied between 4 and 5 hours. Toracic drains had to be applied in 12 patients

  18. Pancreatobiliary versus intestinal histologic type of differentiation is an independent prognostic factor in resected periampullary adenocarcinoma

    Resectable adenocarcinomas in the pancreatic head, by definition 'periampullary', originate from ampullary, duodenal, biliary, or ductal pancreatic epithelium. Typically, periampullary adenocarcinomas have either intestinal or pancreatobiliary type of differentiation, and the type of differentiation might be prognostically more important than the anatomic site of origin. The aim of the study was to determine whether the histologic type of differentiation is an independent prognostic factor in periampullary adenocarcinoma, and whether tumour origin predicts the prognosis in pancreatobiliary type carcinomas independently of resection margin involvement, tumour size, nodal involvement, perineural and vascular infiltration, and degree of differentiation. Histopathologic variables in 114 consecutively resected periampullary adenocarcinomas of pancreatobiliary (n = 67) and intestinal (n = 47) type differentiation were evaluated using a standardized, systematic protocol for evaluation of the resected specimen (study group). Histologic type of differentiation and tumour origin were compared as predictors of survival, and the results were validated by comparison with a historical control group consisting of 99 consecutive pancreaticoduodenectomies performed before standardization of histopathologic evaluation. Associations between histopathologic variables were evaluated by Chi-square and Mann-Whitney tests. Survival was estimated by the Kaplan-Meier method, comparing curves using log-rank test, and by univariate and multivariable Cox regression analysis. Both in the study group (n = 114) and in the historical control group (n = 99), the histologic type of differentiation independently predicted survival, while tumour origin predicted survival only in univariate analysis. Independent adverse predictors of survival in the study group were pancreatobiliary type differentiation (p < 0.001; HR 3.1; CI 1.8–5.1), regional lymph node involvement (p < 0.001; HR 2.5; CI

    Recently, a novel fusion gene resulting from a linkage between the kinesin family member 5B gene (KIF5B; 10p11.22) and the rearranged during transfection gene (RET; 10q11.21) was identified in non-small cell lung cancer (NSCLC). However, the correlation between the KIF5B/RET fusion gene status and the clinicopathological features of surgically-treated lung cancer has not been well characterized. In this study, we have independently investigated the KIF5B/RET fusion gene status in 371 surgically-treated NSCLCs (270 were adenocarcinomas and 101 were squamous cell carcinomas), 60 breast cancers, 11 metastatic lung cancers from colon cancers and thyroid papillary adenocarcinoma cases at the Nagoya City University Hospital. The fusion gene status was analyzed by an RT-PCR-based assay and by using direct sequencing. We detected 3 of 270 cases of KIF5B/RET fusion genes in adenocarcinomas (1.1%) consisting of female and never smokers with mixed subtype adenocarcinomas. The fusion genes were detected exclusively with other mutations, such as EGFR, Kras, Braf, erbB2 mutations, and EML4/ALK fusion. KIF5B/RET fusion was not detected in the cases with squamous cell carcinoma or other types of cancers. From the 3 cases, 2 were KIF5B (exon 15); RET (exon 12) fusions with papillary dominant and 1 case was KIF5B (exon 22); RET (exon 12) fusion with solid dominant adenocarcinoma. The matched normal lung tissues did not display translocation. We reported KIF5B/RET fusion genes as a driver somatic mutation of lung adenocarcinomas. The cinicopathological backgrounds of the KIF5B/RET fusion-positive patients were similar with those of the EML4/ALK fusion-positive patients. The chimeric oncogene may be a promising molecular target for the personalized diagnosis and treatment of NSCLC. PMID:22797671

    Full Text Available The case of a 68 years old patient, smoking since adolescence, with urban origins, obesity history and gastroesophageal reflux symptoms is presented. The patient was diagnosed with gastroesophageal junction adenocarcinoma type III in the Gastroenterology Department of the Provincial University Hospital of Cienfuegos where he arrived with weight loss of about 20 pounds in four months along with dyspeptic manifestations such as stomach acidity, slow digestion, bloating and epigastric pain unrelated to food consumption. No dysphagia was observed as presentation form of the disease. The patient underwent surgery and chemotherapy and has had a favourable outcome up until today. It was decided to publish this article because of the few cases of gastroesophageal junction adenocarcinoma and especially type III that are commonly presented and also because the diagnosis is, unlike this case, usually made at an advanced stage of the diseaseSe presenta el caso de un paciente de 68 años, fumador desde la adolescencia, de procedencia urbana, con antecedentes personales de obesidad y síntomas de reflujo gastroesofágico, al que se le diagnosticó adenocarcinoma de la unión esofagogástrica tipo III, en el Servicio de Gastroenterología del Hospital Provincial Universitario de Cienfuegos, al cual acudió por presentar pérdida de peso de aproximadamente 20 libras en cuatro meses, acompañado de manifestaciones dispépticas: acidez, digestiones lentas, distensión abdominal y epigastralgia no relacionada con la ingestión de alimentos. No manifestó disfagia como forma de presentación de la enfermedad. Fue sometido a tratamiento quirúrgico y quimioterapia y ha tenido una evolución favorable hasta la fecha. Se decidió publicar este artículo debido a la baja frecuencia de presentación del adenocarcinoma de la unión esofagogástrica y en especial el tipo III, así como porque su diagnóstico generalmente se realiza en una etapa avanzada, a diferencia de
