    The prognosis of bronchogenic carcinoma depends on its histology and the time of its first diagnosis. The 5-year-survival rate after radiation treatment is 3-10%. It is much better for tumors detected and operated in an early stage, averaging 21%. The roentgenomorphology of central and peripheral bronchogenic carcinoma and the differential diagnosis is demonstrated on a selected group of 300 patients seen in the "Klinik und Poliklinik für Radiologie" in Munich between 1975 and 1979. In conclusion we think it not justified to hesitate performing bronchoscopy and/or percutaneous needle aspiration lung biopsy in cases of unclear peripheral or central pulmonary shadows, considering the low risks of the two procedures.

    Full Text Available The colonic metastases from bronchogenic carcinoma are rare. We present a 73-year-old man presented with features suggestive of pan colitis after metastasis from undifferentiated large cell carcinoma of the lung. The plain radiograph and computed tomography scan of the chest had revealed a mass lesion in the right lower lobe of lung. He had no evidence of significant lesions elsewhere. Considering the advanced stage and poor differentiation of the tumour, no active therapy was undertaken and he survived for three months.

    Full Text Available "nAdrenal metastases from bronchogenic carcinoma are found in approximately one third of patients at autopsy. Tumors that commonly metastasize to the adrenal gland include bronchogenic carcinoma, breast carcinoma and melanoma and small cell lung cancer, accounting for 6% of the adrenal metastasis. Routine preoperative upper abdominal CT scanning reveals an adrenal mass in approximately 10% of the patients. In selected patients, excision of the primary lung tumor and the isolated adrenal metastasis may improve survival. "nHere a 82-year-old female is presented with a history of 3 months pleuritic chest pain, chronic cough, dyspnea and also abdominal distention and discomfort. Bronchoscopy revealed tumoral vegetation in the posterior segment bronchus of the right lung upper lobe. It was diagnosed as an undifferentiated lung carcinoma pathologically. Abdominal CT scan revealed bilateral large heterogeneous masses in the adrenal glands. Biopsy of the adrenal masses revealed their metastatic nature. The patient was expired before excision of the abdominal masses because of lung cancer with pericardial invasion.

    Full Text Available Merkel cell carcinoma (MCC of the skin is a rare, aggressive, malignant neuroendocrine neoplasm. The tumor classically demonstrates positive immunohistochemistry (IHC staining for chromogranin A(ChrA, cytokeratin 20 (CK20, neuron specific enolase (NSE and/or achaete-acute complex-like 1 (MASH1. The newly identified Merkel cell polyomavirus (MCPyV has been found to be associated with most MCC cases. The primary histologic differential diagnoses of cutaneous MCC is small cell primary bronchogenic carcinoma (SCLC; moreover, both are of neuroendocrine origin. SCLC accounts for approximately 10-15% of all primary lung cancer cases; this histologic subtype is a distinct entity with biological and oncological features distinct from non-small cell lung cancer (NSCLC. In contradistinction to MCC, SCLC is classically IHC positive for cytokeratin 7 (CK7 and transcription factor (TTF-1. Similar to SCLC, MCC cell lines may be classified into two different biochemical subgroups designated as Classic and Variant. In our review and case report, we aim to emphasize the importance of a multidisciplinary approach to the approach to this difficult differential diagnosis. We also aim to comment about features of the cells of origin of MCC and SCLC; to summarize the microscopic features of both tumors; and to review their respective epidemiologic, clinical, prognostic and treatment features. We want to emphasize the initial workup study of the differential diagnosis patient, including evaluating clinical lymph nodes, a clinical history of any respiratory abnormality, and chest radiogram. If a diagnosis of primary cutaneous MCC is confirmed, classic treatment includes excision of the primary tumor with wide margins, excision of a sentinel lymph node, and computed tomography, positron emission tomography and/or Fluorine-18-fluorodeoxyglucose positron emission tomography scan studies

    Full Text Available The objective of this study was to present some clinical and radiological manifestations of PNS in relation to bronchogenic carcinoma (BC and to evaluate the usefulness of imaging findings in the diagnosis of asymptomatic BC. In the study group of 204 patients (146 male and 58 female with proven bronchogenic carcinoma, PNS was present in 18 (8.62% patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2% patients with symptoms related to primary tumours while the second one consisted of 5 (27.7% patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma, a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma, a case of Cushing Syndrome (small-cell carcinoma, and hyper-calcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an

    Full Text Available Cardiac metastases in bronchogenic carcinoma may occur due to retrograde lymphatic spread or by hematogenous dissemination of tumour cells, but direct invasion of heart by adjacent malignant lung mass is very uncommon. Pericardium is frequently involved in direct cardiac invasion by adjacent lung cancer. Pericardial effusion, pericarditis, and tamponade are common and life threatening presentation in such cases. But direct invasion of myocardium and endocardium is very uncommon. Left atrial endocardium is most commonly involved in such cases due to anatomical contiguity with pulmonary hilum through pulmonary veins, and in most cases left atrial involvement is asymptomatic. But myocardial compression and invasion by adjacent lung mass may result in myocardial ischemia and may present with retrosternal, oppressive chest pain which clinically may simulate with the acute myocardial infarction (AMI. As a result, it leads to misdiagnosis and delayed diagnosis of lung cancer. Here we report a case of non-small-cell carcinoma of right lung which was presented with asymptomatic invasion in left atrium and retrosternal chest pain simulating AMI due to myocardial compression by adjacent lung mass, in a seventy-four-year-old male smoker.

    @@ Introduction The association between pulmonary interstitial fibrosis and the development of bronchogenic carcinoma in a patient with scleroderma has been reported rarely[1]. It is hypothesized that intense epithelial proliferation that is accompanied by the .brotic process increases the occurrence of carcinomatous changes[2]. We report the case of a pa-tient who presented with 3-year history of Raynaud's phenomenon, gradual tightening of the skin which was ignored by the patient and her family members, and a 2-week history of severe respiratory dis-tress with left shoulder and upper back pain followed by the develop-ment of paraparesis. After a series of examinations, the patient was diagnosed with scleroderma and simultaneously with bronchogenic carcinoma and multiple distant metastases.

    Orbital metastasis in systemic cancer is known to occur and occurs in up to 7% of all systemic cancers. Orbital features typically present after the diagnosis of the primary tumor. In about 20% of cases, there is no known primary cancer at the time of presentation with orbital metastatic disease. Here we report a case of a 60-year-old male smoker, in whom proptosis, due to metastasis in greater wing of left sphenoid bone secondary to bronchogenic carcinoma, was the initial symptom. We could not find in literature metastasis to greater wing of sphenoid bone due to small cell carcinoma of lung.

    Full Text Available Abstract Introduction Double primary bronchogenic carcinoma and papillary carcinoma of the thyroid are extremely rare. We describe the case of a patient who underwent surgical resection for these two cancers. Case presentation A 56-year-old man presented to our hospital complaining of a cough with blood-tinged sputum. A slowly growing mass in the left lobe of the lung had been noted for about 1 year. He underwent video-assisted thoracic surgery of the left lower lobe and mediastinal lymph node dissection through an 8 cm utility incision. Pathology revealed a well-differentiated adenocarcinoma and the dissected lymph nodes were negative for malignancy. He also complained of a mass in his neck, which had grown slowly for over 5 years. A computed tomography scan of the neck revealed a left thyroid mass compressing the trachea towards the right side. There was no cervical lymphadenopathy. A left thyroid lobectomy was performed and pathology revealed a papillary carcinoma. Thus, he underwent a second operation to remove the right lobe of the thyroid. He underwent subsequent adjuvant chemotherapy. Conclusion In a review of the literature, it appears that there has only been one previously reported case of these two cancers, which was in Japan. The relationship between these two cancers is still unclear, and more case reports are required to determine this relationship.

    Full Text Available BACKGROUND Lung cancer is presently the most common malignant disease (13% of all cancers and the leading cause of cancer deaths (19% of all cancer deaths in the world in all age groups and in both sexes. It is the leading cause of cancer deaths in developed as well as in developing countries. OBJECTIVE The present study was conducted to study the various clinical and pathological presentations of bronchogenic carcinoma. MATERIALS AND METHODS A total of 82 patients with histologically proven bronchogenic carcinoma, hospitalized between 2012 and 2014 at a tertiary care centre, Pune, India, were analysed. RESULT Out of a total of 82 diagnosed cases, average age was 61 years, nearly 80.0% were males. Smoking was the risk factor in 63.41%. About 2% of female patients were smokers. Six (7.3% patients were <40 years of age at the time of diagnosis. Fiberoptic bronchoscopy (75.60% was found to be the most efficient diagnostic procedure. Histologically, adenocarcinoma, squamous cell carcinoma, non-small cell carcinoma and small cell carcinoma were seen in 57.31%, 24.39%, 9.75% and 6.09% cases, respectively. Distant metastases to organs like nodes, liver, adrenals and bones were present in 67%. CONCLUSION This study shows that adenocarcinoma is the most common type of lung cancer and clinical and radiological suspicion should lead to the prompt diagnosis and management.

    We describe the case of a 60 year old female smoker who presented with a three month history of weight loss (14 Kg), generalized abdominal discomfort and malaise. Chest radiography demonstrated a mass projected inferior to the hilum of the right lung. Computed Tomography of thorax confirmed a lobulated lesion in the right infrahilar region and subsequent staging abdominal CT demonstrated a low density lesion in the neck of the pancreas. Percutaneous Ultrasound guided pancreatic biopsy was performed, histology of which demonstrated pancreatic tissue containing a highly necrotic small cell undifferentiated carcinoma consistent with metastatic small cell carcinoma of the bronchus.

    The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

    Objective: To study the serum level of estradiol, progesterone and testosterone (SEL, SPL and STL) and the expression of the receptors of estradiol and progesterone (ER and PR) in 53 cases of bronchogenic carcinoma. Methods:ER and PR in the tissue of the carcinoma were determined with enzyme-linked affinity histochemical method. SEL, SPL and STL were measured with double antibody radioimmunoassay. Results: Most of ER and PR were present in the cytoplasm of the malignant cells (58.2 % ) and the positive rates of ER and PR were 49.1% and 54.7 % respectively. SEL and SPL were significantly higher in the patients with lung cancer than in the subjects of the control groups ( P < 0.05), no matter whether ER and PR were positive or negative. SEL and SPL were lower in the ER positive, PR positive and both ER and PR positive groups than in the ER negative, PR negative and both ER and PR negative groups. Conclusion: The existence of ER and PR in the patients with bronchogenic carcinoma indicates that the pathogenesis of bronchogenic carcinoma is sex hormone dependent to some extent. ER and SEL are negatively correlated with a correlative coefficient of - 1.

    Full Text Available Background: The importance of rapid and accurate cytopathological diagnosis in bronchial cancers is increasing due to advances in treatment modalities.Aims: We evaluated the diagnostic methods and cytologic subtypes of bronchial cancers to determine the diagnostic reliability of different bronchoscopic techniques.Material and methods: Retrospective data were obtained from the hospital files and pathological specimens of the patients with diagnosis of primary lung cancer from a period of 36 months. Cytological tumor typing was determined using histopathology of bronchoscopic forceps biopsy (FB, bronchial-bronchoalveolar lavage (BL, bronchial brushing (BB, transbronchial fine-needle biopsy. Computed tomography or ultrasonography guided transthoracic biopsy and surgical biopsies were used where the other interventional methods were inadequate for diagnosis.Results: A total of 124 patients were diagnosed during study period. 119 (96% of them were male. The median age was 68, ranging between 36 and 88 years. Histopathologic subtypes were determined as non-small cell carcinoma (NSCC in 104 (83.9%, squamous cell carcinoma in 64 (51.6%, adenocarcinoma in 16 (12.9%, NSCC not otherwise specified in 24 (19.3% and small cell carcinoma in 20 (16.1% patients. The combination of FB, BL and BB established the diagnosis of bronchogenic carcinoma in most of the cases (92.6%.Conclusions: Lung cancer is seen commonly in elderly male patients with smoking history and squamous cell carcinoma is the most common cytologic type. High diagnostic accuracy can be achieved by a combination of bronchoscopic FB, BB and BL procedures. Keywords: Bronchoscopy; Lung cancer; Bronchial brushing

    Full Text Available Background and objective Lung transplantation is an efficient therapeutic option for patients with end-stage pulmonary diseases, but less is known about lung cancer after lung transplantation. The aim of this study is to improve the awareness, diagnosis and treatment of bronchogenic carcinoma after lung transplantation with a case report and related literatures. Methods We reported a 65-year-old male with idiopathic pulmonary fibrosis (IPF who underwent right lung transplantation under extracorporeal membrane oxygenation (ECMO support in May 2007 in our hospital. The patient recovered smoothly and discharged from the hospital 46 days after the procedure with regular follow-up. Immunosuppression therapy was triple drug maintenance regimen including tacrolimus (Tac, mycophenolate mofetil (MMF and steroids. Results Small cell lung cancer in the left lung with multiple osseous metastases was found 13 months after the lung transplantation. Symptoms were relieved a bit by administering chemotherapeutics (etoposide and cisplatin for 4 cycles. However, the patient was succumbed to his illness within 11 months after the diagnosis of lung cancer. Conclusion Lung cancer after lung transplantation has been suggested as one of causes of late mortality with the risk factors such as chronic obstructive pulmonary disease (COPD, IPF, cigarette smoking history and immunosuppression etc. Early diagnosis and treatment are very important to improve the prognosis.

    Intrapleural immunotherapy, radiotherapy and chemotherapy were employed in that sequence in 22 patients with Stage III non-oat cell bronchogenic carcinoma confined to the thorax. Seven patients received intrapleural BCG in a pilot study and 15 were randomized between intrapleural BCG and intrapleural saline. Isoniazid was begun on day 14 and irradiation (3000 rad in 10 fractions) to the primary lesion, mediastinum and ipsilateral supraclavicular nodes was started on day 21. One to two weeks following irradiation, CAMP chemotherapy was initiated (Cyclophosphamide 300 mg/M/sup 2/ iv, d. 1,8; Adriamycin 20 mg/M/sup 2/ iv, d. 1,8; Methotrexate 15 mg/M/sup 2/ iv, d. 1,8 and Procarbazine 100 mg/M/sup 2/ p.o., d. 1 to 10). Chemotherapy was given for a total of six months. Two patients expired prior to radiotherapy (1 tumor progression, 1 myocardial infarction) and 2 patients were lost to follow-up. Nausea, vomiting, alopecia and fatigue were universal side effects of the chemotherapy. Esophagitis occurred in 9 patients, 7 prior to and 2 after initiation of Adriamycin. In only one case did Adriamycin exacerbate a previous radiation esophagitis. No patient developed clinical radiation pneumonitis, although all had eventual radiation fibrosis. Congestive heart failure occurred in 1 patient with known valvular heart disease and responded to diuretics. Three patients developed localized herpes zoster infections. One patient developed radiation myelitis one year after initiating therapy and six months after completing all chemotherapy. The major side effect was leukopenia with relative platelet sparing. Although significant morbidity was encountered in this primarily older patient population (mean age 64.8 years) recall reactions involving irradiated intrathoracic structures were not a significant clinical problem.

    The X-ray film, CT and MRI are main diagnostic modalities for bronchogenic cancer. The high-voltage film and high resolution CT(HRCT) are important to the early and differential diagnosis of pulmonary cancer. The MRI and reformatted images from spiral HRCT are valuable to the tumor staging. The early appearances of central pulmonary cancer are stenosis of bronchus, thickening of bronchial wall, nodules in bronchus and air-way obstructive changes. The early peripheral pulmonary cancer often appears as a small nodule or patchy shadow on X-ray film. HRCT usually reveals it as the lobulated nodule, air-bronchogram, marginal spiculae and pleural indentation. In addition, contrast enhanced CT or MRI can provide more diagnostic information. Percutaneous pulmonary biopsy is an important diagnostic procedure. The multiplanar reconstruction, 3D reconstruction and virtual bronchoendoscopy of spiral CT can demonstrate lesions in various aspects, and hence play additional roles in the diagnosis of bronchogenic cancer. For tumor metastasis, CT and MRI can show the involvement of lymph nodes and 3D CT angiography and MRI angiography can accurately reveal the involvement of great vessels. MRI plays a primary role in the diagnosis of chest wall invasion. The central pulmonary cancer should be differentiated from tuberculosis and chronic pneumonia. The periphery pulmonaral cancer should be differentiated from tuberculoma, chronic pneumonia and other solitary nodular lesions. If we make the most of the chest radiography and chest CT, and selectively use other imaging techniques, the accuracy of early diagnosis and differential diagnosis will be remarkably improved.%肺癌的主要影像检查方法为X线胸片、CT、MRI等,其中高电压胸片、高分辨CT是早期发现及鉴别诊断的最重要的方法。螺旋CT的影像重建技术和MRI对于肿瘤的分期有重要价值。中央型肺癌的早期X线表现为支气管的阻塞性改变,HRCT显示支气管狭窄、

    Full Text Available A 21 year cid black man, native from Chocó (Colombia, variously employed, who presented with a respiratory difficulty syndrome of two months of evolution, right pleuritic pain, congestive cardiac failure and systemic symptoms. A homogeneic white .grayish tumor measuring 8 by 10 cm with necrotic areas was found at necropsy. The tumor originated in the main bronchial tube of the lower and middle lobes of the right lung and invaded the entire pericardial vicinity forming a cuirass and causing tumoral constrictive pericarditis. Microscopic studies revealed a well differentiated squamous type bronchogenic carcinoma. Bronchogenic carcinomas are frequently associated with cigarette smoking. However, their incidente has increased among non. smokers, suggesting the possibility that there are other causal factors, such as atmospheric contaminants, genetic predisposition, diets deficient in vitamin A and carotene, presente of certain viruses and immunologic changes. Lung cancer constitutes 16% among the types of cancer suffered by men and 13% among women, it has its greatest incidente in groups between 40 and 70 years of age and only 1 to 5 percent of thecasesoccur in groupsunder theageofforty years.

    Objective: To evaluate the efficacy of double-phase contrast material-enhanced computed tomography (CT) in assessing no-surgical treatment response in bronchogenic carcinoma preliminarily. Methods: 52 patients with bronchogenic carcinoma after no-surgical treatment underwent double-phase contrast material-enhanced computed tomography. Two spiral CT scans were obtained at 25 and 90 seconds respectively after nonionic contrast material was administrated via the antecubital vein at a rate of 4 mL/s by using an autoinjector. Precontrast and postcontrast attenuation on every scan was recorded and peak height was calculated. Enhancement pattern was evaluated on the images obtained at 25 and 90 seconds after injection of contrast medium. Results: Precontrast attenuation, postcontrast attenuation at 25 and 90 seconds were 42.20±7.43 Hu, 57.35 ± 10.09 Hu and 71.85 ± 12.45 Hu, respectively. No statistically significant difference in precontrast attenuation was found between our results in the study and the results in our old study (mean precontrast attenuation 40.70 Hu) which was obtained in cases before therapy (t = 1.455, P = 0.152 > 0.05). Peak height of bronchogenic carcinoma after no-surgical treatment (29.46 ± 10.85 Hu) were significantly lower than that of bronchogenic carcinoma before therapy obtained in our old study (mean peak height 35.79 Hu; t = 4.206, P = 0.001 < 0.05). 32 of 52 cases showed homogeneous enhancement at 90 seconds. Of the 32 cases, there were 21 with inhomogeneous enhancement, 7 with inhomogeneous enhancement, 2 with central enhancement and 2 with peripheral enhancement at 25 seconds. Conclusion: Bronchogenic carcinoma after no-surgical treatment shows a gradual increase to the peak height after administration of contrast material. Peak heights can reflect the blood supply of bronchogenic carcinoma and might be index for evaluation of no-surgical treatment response in bronchogenic carcinoma.

    Full Text Available Bronchogenic cysts occur due to the anomalous development of the primitive tracheobronchial tree early in fetal life. They are usually present in middle mediastinum. Rarely, they have been found in other locations. We describe two patients with subcutaneous bronchogenic cysts located over manubrium sterni with special emphasis on the difficulties in pre-operative diagnosis. The two boys were managed by complete excision of the cysts. The children are well on follow-up.

    目的:探讨慢性阻塞性肺疾病(COPD)与支气管肺癌的临床关系,为临床早期诊断和治疗提供依据。方法54例COPD合并支气管肺癌患者作为观察组,同期54例单纯肺癌患者作为对照组,比较两组患者临床症状和体征、病理类型及治疗方法的差异。结果两组患者干咳、声音嘶哑、胸膜腔积液及骨痛例数比较差异均无统计学意义(P>0.05),观察组发热、胸痛、痰中带血、呼吸困难及肺不张例数均显著多于对照组(P0.05),腺癌、小细胞癌及其他非小细胞癌类型,两组比较差异有统计学意义(P0.05). The observation group had much more cases of fever, chest pain, blood-stained sputum, dyspnea, and pulmonary atelectasis than the control group (P0.05). The difference of adenocarcinoma, small cell carcinoma, and non small cell carcinoma had statistical significance between the two groups (P<0.05). The observation group was treated mainly by non-surgical method, while the control group received surgical treatment.ConclusionThe clinical characteristics of COPD combined with bronchogenic carcinoma lacks of specificity. The imaging manifestations of chest pain, hemoptysis, dyspnea, pulmonary atelectasis, and pleural effusion of COPD patients show the possibility of complicated lung cancer, and early screening examination is necessary.

    2011-01-01

    The authors describe a rare case of metastatic bronchogenic adenocarcinoma in a 55-year-old man presenting with concomittant solitary lytic skull lesion and ischaemic stroke. Metastatic bronchogenic carcinoma is known to present as lytic skull lesions. Primary brain tumours are also known to cause ischaemic brain injury. An underlying stroke risk may be exagerated by cranial tumour surgery. Patients with brain tumours are well known to be predisposed to an increased risk of developing thromboembolic disease. It is unusual to see metastatic bronchogenic adenocarcinoma presenting as ischaemic stroke with a background of concomittant cerebral metastasis. The aetio-pathogenesis of this rare occurrence is discussed with a review of literature.

    The main purpose of this work is to evaluate the role of CT in identifying other morphological signs of met static lymph node involvement from non small cell bronchogenic carcinoma. This is done to improve N staging, a critical step in this disease. In fact, since diameter is the only criterion used to distinguish normal form abnormal lymph nodes, mediastinal CT only has 80% diagnostic accuracy. 137 patients with known or suspected lung cancer were examined with Helical CT during early and late arterial phases (2 min. delay, 3 mm thickness, 5 mm inter slice gap) to depict node characteristics. Mediastinal lymph nodes, located according to the American Thoracic Society mapping, were considered normal when they were not visible or, if visible, less than 1 cm in diameter and of homogeneous density; lymph nodes over 1 cm in diameter and homogenous density were considered reactive. A lymph node was considered metastatic when, independent of size, the following signs were found: central hypo density; hyperdense thin/thick rim, with nodules within; hyperdense strands or diffuse hyper density in perinodal adipose tissue. The tumor site was also considered. Seventy patients were excluded because they were inoperable. Sixty-five of the remaining 67 patients were operated on, 1 underwent mediastinoscopy and another one mediastinoscopy followed by surgery. Based on above CT signs, 46 patients were staged as N0, 61 as N1 and 15 as N2. In 44/46 N0 patients there was agreement between anatomical and pathologic findings; 3 of the 44 patients had lymph nodes over 1 cm in diameter and with homogeneous density. Micrometastases to mediastinal lymph nodes (N2) were found at histology in 2/46 patients (CT false negatives). In the 6 N1 and the 15 N2 patients there was complete agreement between anatomical and pathologic findings; in particular, 9 N2 patients had lymph nodes less than 1 cm in diameter with signs of metastasis and 4 had lymph nodes over 1 cm in diameter with signs of

    Spinal bronchogenic cysts are rare congenital lesions. The authors describe their experience in the treatment of a 17-year-old boy who presented with back pain and paresthesia in both lower extremities. Lumbar MR imaging revealed the presence of an intramedullary cystic lesion at the conus medullaris and histopathological analysis revealed a bronchogenic cyst. To the best of the authors' knowledge, this is the first report of an intramedullary spinal bronchogenic cyst arising at the conus; all previously reported spinal bronchogenic cysts were either intradural extramedullary or not located at the conus.

    Objective To investigate the clinical manifestations, lung function and therapy of patients with primary bronchogenic carcinoma complicated with chronic obstructive pulmonary disease (COPD). Methods 365 patients with primary bronchogenic carcinoma were recruited retrospectively. The patients were analyzed by COPD-complicated and COPD-free groups. The clinical manifestations, lung function (especially FEV1 ) ,pathological types and progression-free survival (PFS) were analyzed. The use of inhaled corticosteroids for treatment of COPD was also recorded. Results There was 62. 2% patients (227 cases) complicated with COPD with an average age of (66.1 ± 9. 3 ) yrs, 77. 5% of male, 82. 4% of smokers, and 46. 3 % of past histories of respiratory disorders. Those in COPD-free were aged (54. 8 ±5.6) yrs, with 55. 8% of male,62. 3% of smokers,and 30. 4% of past histories of respiratory diseases. The COPD-complicated patients had lower lung function than that of COPD-free [ (68. 6 ±9. 7)% vs. (75. 3 ±7. 5)% in FEV, % pred and ( 65. 9 ± 8. 5 ) % vs. ( 75. 6 ± 9. 1 ) % in FEV/FVC, P < 0.05 ]. The COPD-complicated patients were more likely to have squamous carcinoma (43. 2% us. 31. 2% , P < 0. 05 ) and small cell lung cancer (20.7% vs. 15.2%,P < 0.05).Moreover,performance status (PS)scores (3.3 ± 0. 5 vs. 2. 8 ±0.4) and PFS (5. 9 ± 1. 6 vs. 7. 5 ± 2. 1) were worse in the COPD-complicated patients than that of the COPD-free patients. Only 71 cases of the COPD-complioated patients received regularly inhaled corticosteroids for COPD treatment. These patients had better PS scores and PFS than others without corticosteroids treatment. Conclusions Primary bronchogenic carcinoma patients with COPD comorbidity are commonly encountered. Clinicians should be aware of the clinical manifestation and corticosteroids prescription should be recorded to improve the quality of life and prognosis.%目的 探讨原发性支气管肺癌合并慢性阻塞性肺疾病( COPD)的临床特征

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    Full Text Available Abstract Background Deregulated cell cycle progression and loss of proliferation control are key properties of malignant cells. In previous studies, an interactive transcript abundance index (ITAI comprising three cell cycle control genes, [MYC × E2F1]/p21 accurately distinguished normal from malignant bronchial epithelial cells (BEC, using a cut-off threshold of 7,000. This cut-off is represented by a line with a slope of 7,000 on a bivariate plot of p21 versus [MYC × E2F1], with malignant BEC above the line and normal BEC below the line. This study was an effort to better quantify, at the transcript abundance level, the difference between normal and malignant BEC. The hypothesis was tested that experimental elevation of p21 in a malignant BEC line would decrease the value of the [MYC × E2F1]/p21 ITAI to a level below this line, resulting in loss of immortality and limited cell population doubling capacity. In order to test the hypothesis, a p21 expression vector was transfected into the A549 human bronchogenic carcinoma cell line, which has low constitutive p21 TA expression relative to normal BEC. Results Following transfection of p21, four A549/p21 clones with stable two-fold up-regulated p21 expression were isolated and expanded. For each clone, the increase in p21 transcript abundance (TA was associated with increased total p21 protein level, more than 5-fold reduction in E2F1 TA, and 10-fold reduction in the [MYC × E2F1]/p21 ITAI to a value below the cut-off threshold. These changes in regulation of cell cycle control genes were associated with restoration of cell proliferation control. Specifically, each transfectant was capable of only 15 population doublings compared with unlimited population doublings for parental A549. This change was associated with an approximate 2-fold increase in population doubling time to 38.4 hours (from 22.3 hrs, resumption of contact-inhibition, and reduced dividing cell fraction as measured by flow

    Full Text Available A apresentação de lesão sincrônica pulmonar e hepática em um paciente com antecedente de carcinoma broncogênico operado gera a suspeita de recidiva tumoral e indica a necessidade de re-estadiamento. Apresentamos o caso de um paciente de 71 anos submetido à lobectomia pulmonar com ressecção de pericárdio e linfadenectomia mediastinal (T3N0M0. Cinco anos após a cirurgia, detectou-se a presença de uma nova lesão pulmonar. No re-estadiamento, foi diagnosticada uma lesão sincrônica no fígado. Apesar da forte suspeita de recidiva tumoral, prosseguiu-se a investigação e uma punção hepática revelou carcinoma hepatocelular. Para esclarecer a etiologia da lesão pulmonar (hipóteses de recidiva de carcinoma brônquico ou de metástase de carcinoma hepatocelular, foi realizada uma biópsia a céu aberto, compatível com reação inflamatória crônica com focos de antracose e de calcificação distrófica. O paciente foi então submetido à ressecção hepática não-regrada com intuito curativo. Teve boa evolução, com alta no 10º dia de pós-operatório. O presente relato destaca a importância do diagnóstico histopatológico em pacientes com antecedente de carcinoma broncogênico e suspeita de recidiva.

    Objective: The aim of this study was to evaluate the efficacy of changes in the sum of the enhancement area lon- gest diameters (LD) in assessing no-surgical treatment response in bronchogenic carcinoma preliminarily. Methods: Twenty- two patients with bronchogenic carcinoma underwent two-phase contrast material-enhanced computed tomography prior to and after stopping no-surgical treatment more than one-month respectively. Two spiral CT scans were obtained at 25 and 90 sec respectively after nonionic contrast material was administrated via the antecubital vein at a rate of 3 mUsec by using an autoinjector. The sum of the tumor LD prior to treatment, after treatment and the sum of the post-treatment tumor enhance- ment area LD on the images obtained at 90 sec after injection of contrast medium were recorded. Enhancement pattern was evaluated on the images obtained at 25 and 90 sec after injection of contrast medium. Response Evaluation Criteria In Solid Tumors (RECIST) guidelines were adopted to evaluate treatment response. The significance of the difference among groups was analyzed by means of ANOVA. Results: The sum of the tumor LD prior to treatment, that of after treatment and the sum of the post-treatment tumor enhancement area LD on the images obtained at 90 sec after injection of contrast medium were (4.48 + 1.19), (3.98 + 1.50), (3.35 + 1.11) cm respectively and there were statistically significant differences among them (F = 4.273, P = 0.018). The sum of the tumor LD prior to treatment was significantly higher than that of the post-treatment tumor enhancement area (P = 0.005).

    Objective: The aim of the study was to determine the ef iciency and ef ectiveness of picture archiving and com-munication system (PACS) workstation in detecting enhancement pattern of peripheral bronchogenic carcinoma. Methods:The 62 patients with peripheral bronchogenic carcinoma underwent two-phase contrast material-enhanced multislices com-puted tomography (MSCT) of the chest in a single-breath-hold technique. Two spiral CT scans were obtained at 25 s and 90 s respectively after nonionic contrast material was administrated via the antecubital vein at a rate of 4 mL/s by using an autoinjector. Precontrast and postcontrast attenuation on every scan were measured on PACS and CT workstations respec-tively and peak height was calculated. Enhancement pattern was evaluated on the image obtained at 90 s after injection of contrast medium on PACS and CT workstations respectively. Results: No statistical y significant dif erence in precontrast attenuation, postcontrast attenuation at 25 s and 90 s was found between these measured on a PACS workstation [(40.21 ± 7.03) HU; (55.53 ± 11.09) HU; (75.95 ± 13.45) HU] and those [(39.01 ± 8.95) HU; (56.01 ± 10.91) HU; (76.03 ± 11.95) HU] on a CT workstation (t = 1.140, P = 0.256 > 0.05; t = 1.580, P = 0.149 > 0.05; t = 1.505, P = 0.150﹥0.05). The peak height that calculated on a PACS workstation was 35.74 HU (20 HU). There was not statistical y significant dif erence in peak height between that calculated on a PACS workstation and that on a CT workstation [(37.02 ± 12.05) HU; t = 2.001, P = 0.099 >0.05]. The tumors showed same enhancement pattern on PACS workstation and CT workstation. Of the 62 cases, 38 showed homogeneous enhancement, 17 showed heterogeneous enhancement, five showed peripheral enhancement, two showed central enhancement, at 90 s. The enhancement pattern revealed on PACS workstation was consistent with feature of periph-eral bronchogenic carcinoma. Conclusion: The ef iciency and ef ectiveness of PACS

    Full Text Available Bronchogenic cysts arise from an abnormal budding of the ventral diverticulum of the foregut or the thracheobronchial tree during embryogenesis. An intrapericardial location is an extremely rare finding. Symptoms are related to cardiac structure compression, but in most case they remain asymptomatic. We present a case of intrapericardial bronchogenic cyst in a young patient, resected entirely with repair of right lateral proximal ascending aorta with PTFE graft.

    Between 1974 and 1993, 22 patients with bronchogenic cysts were operated on in our hospital; there were 14 men and 8 women, ranging in age from 11 to 62 years, The cyst locations were mediastinal in 13 (59.1%) and intrapulmonary in 9 (40.9%). There were symptoms (chest pain and recurrent bronehiolits) in 20 patients (91%). The preoperative complications included infection in the lung and in the cyst and dysphagia due to esophageal eornpression. Chest pain was the main symptom in mediastinal cyst and recurrent infection of lung in intrapulmonary cyst. Plain chest radiograms showed that a rousd shadow, occasional air-fluid levels, and peripheral calcification may be found in cysts. An operation is the best treatment for cysts. All cysts were completely excised. No postoperative complieations, late complica-tions, or recurrence developed in our patients.

    Full Text Available Difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. Mediastinal masses are not common findings, but are important variables. Bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. We present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchogenic cyst was detected in this patient. The patient had history of asthma since she was eight months old. She had a history of several asthma attacks which had partly responded to asthma management. During the last episodes of asthma attacks, she was hospitalized in Pediatric Intensive Care Unit. Imaging studies showed a 4×3 cm mass in the posterior part of the thoracic cavity that had led to tracheal narrowing was found for which the patient underwent thoracotomy and in surgical exploration a cyst that had compressed the thoracic trachea. Pathological examination of the cyst revealed a bronchogenic cyst. Bronchogenic cyst is an uncommon developmental abnormality but in a patient with obstructive pattern of airways it should be considered in differential diagnosis of asthma, especially if the asthma management is not successful.

    Objective To investigate the clinical features and management of bronchogenic cyst in the adults. Methods We retrospectively reviewed 50 patients admitted to our hospital with histopathologically proved bronchogenic cyst from January 1983 to December 2007. Of all the patients, 28 were male and 22 were female, with an average age of 36.9 (range, 18 to 64) years. The symptoms, location of the cysts, imaging evaluation, surgical treatment manner, and outcome of these patients were analyzed. Results Symptoms were present in 33 of the 50 patients, and cough was the most common symptom. Thirteen patients presented with complications: hemoptysis, infected cyst, dysphagia, paralysis, and hoarseness. The locations of the cysts included the mediastinum (28 cases), pulmonary parenchyma (12 cases), hilar area (3 cases), visceral pleura (1 case), and some rare locations including the intestinal mesentery (1 case), retroperitoneum (1 case), adrenal gland (1 case), neck (2 cases), and dura matter of the cervical vertebrae (1 case). Chest X-ray was performed in 36 patients and computed tomography (CT) was performed in 41 patients. The bronchogenic cyst in CT was characterized as a round, well circumscribed, unilocular mass, with density ranging from that of water to high density (0-50 Hu). As for treatment, complete resection of the bronchogenic cyst was performed in 47 (94%) patients, subtotal resection was performed in 3 (6%) patients. Open surgery was performed in 45 (90%) patients, and thoracoscopy (video-assisted thoracic surgery) was performed in 5 (10%) paitients. Of the 12 patients with intrapulmonary cyst, 11 patients underwent lobectomy and 1 patient underwent wedge resection. Postoperative sequelae occurred in 2 patients, 1 with persistent air leakage and 1 with hoarseness. All patients were proved with bronchogenic cyst pathologically. The average follow-up period was 6.5 years (range, 4 months to 10 years), and no late sequelae or recurrence of the cyst occurred

    We experienced a rare case of anterior mediastinal bronchogenic cyst. A 55-year-old female was admitted to our hospital because of paroxysmal supraventricular tachycardia (PSVT) and an abnormal shadow on the chest computed tomography. She had a 5.5 cm tumor at anterior mediastinum. The tumor was surgically removed completely by video assisted thoracoscopic surgery, and the diagnosis of bronchogenic cyst was established pathologically. After surgery, PSVT has disappeared.

    Objective: To look for secondary bacterial infections in bronchogenic carcinoma (BCA) with resistant organisms harboring bla genes considering the paucity of relevant studies. Methods:A total of 137 confirmed cases of BCA and 34 healthy volunteers were studied for the occurrence and prevalence of blaCTX-M and and blaAmpC harboring-enterobacteriaceae. A subset of these patients (n=69) was previously reported for the secondary infection with the Aspergillus species. Bronchoalveolar lavages (BAL) were subjected for bacterial and fungal cultures and the bacterial isolates were screened by multiplex PCRs for the presence of blaCTX-M and blaAmpC. The isolates were also screened for the association of insertion sequence (IS26) by PCR and characterized by RAPD for any clonal relatedness. Results: A total of 143 bacterial isolates were obtained from 137 BAL specimens of BCA patients. The Enterobacteriaceae-isolates were multidrug-resistant showing concomitant resistance to fluoroquinolones and aminoglycosides. Both blaCTX-M and blaAmpC of CIT family were detected in 77.4% and 27.4% isolates, respectively. Sequencing revealed the presence of blaCTX-M-15 and blaCMY-6. Twenty one percent of the isolates were simultaneously harboring blaampC and blaCTX-M-15. IS26 PCR and RAPD typing revealed the presence of diverse bacterial population but no predominant clone was identified. The present study also suggests strong association of aspergillosis with lung cancer and further strengthens the potential use of non-validated serological tests suggested earlier. Conclusions: We emphasize that all patients of bronchogenic carcinoma should also be screened for secondary bacterial infections, along with secondary fungal infections, so as to introduce early and specific antimicrobial therapy and to prevent unwanted deaths.

    In this work the authors report two cases of bronchogenic cyst. The first one, in a 69-year-old female patient, with thoracic pain and dyspnea. At the chest X-ray, a mass in the superior mediastinum was observed. Computed tomography of the thorax showed a cystic expansible formation without impregnation by the contrast agent. The patient was referred to thoracic surgery, where she had resected theexpansible formation, that presented histological characteristics of bronchogenic cyst. The other case, in a 50-year-old female patient, that presented symptoms of malaise, retrosternal pain, dry cough, dyspnea and hemoptysis. The chest X-ray evidenced mass in the posterior mediastinum, projected near the helium of the right lung. Computed tomography of the thorax showed a cystic expansible formation, without impregnation by the contrast agent, located in the posterior mediastinum. The patient was submitted to bronchoscopy, videothorascopy and, finally, to thoracotomy, in which the cystic lesion was resected, whose definitive diagnosis, after histopathological examination, was bronchogenic cyst.

    Congenital pericardial defects are a rare anomaly, found during autopsy and cardiothoracic surgery. We describe a case of a 69-year-old female, with a right-sided congenital pericardial defect associated with a giant bronchogenic cyst (BC) found during surgery. The cyst was resected and the patient developed arrhythmia following surgery. A review of the literature in Japan was performed, focusing on congenital anomalies associated with pericardial defects and its pathogenesis. We paid particular attention to complications following thoracic surgery in patients with pericardial defects and indications of pericardial reconstruction in such patients. PMID:27621900

  9. Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

    2016-07-01

    Full Text Available Superior vena cava (SVC syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

    Lung cancer is a dreadful disease which claims to be more life threatening as compared to total sum up of colon, prostate and breast cancers. Thus, there is an urgent need to develop an effective delivery approach for its management. Paclitaxel (PTX) is one of the well-known choice as antineoplasitic agent used for the treatment of different types of human cancers such as non-small-cell lung, head and neck cancers, leukemia, breast, ovarian and melanoma. Lactoferrin (Lf), a "multifunctional protein" is crucial for natural immunity which is secreted by exocrine glands. Lf receptors are expressed on the apical surface on bronchial epithelial cells. These over-expressed LF receptors can be utilized for the transportation of Lf-conjugated drug or nanocarrier devices. The present study was aimed to develop PTX-loaded Lf-coupled solid lipid nanoparticles (SLNs) for the treatment of lung cancer. PTX-loaded SLNs were prepared, characterized and then coupled with Lf using carbodiimide chemistry. The formulations were characterized by transmission electron microscopy, particle size, polydispersity index and zeta potential, whereas Lf conjugation was confirmed by FT-IR and ¹H NMR and efficiency of prepared system was evaluated by in vitro, ex vivo and in vivo evaluations. The ex vivo cytotoxicity studies on human bronchial epithelial cell lines, BEAS-2B, revealed superior anticancer activity of Lf-coupled SLNs than plain SLNs and free PTX. In vivo biodistribution studies showed higher concentrations of PTX accumulated in lungs via Lf-coupled SLNs than plain SLNs and free PTX. These studies suggested that Lf-coupled PTX-loaded SLNs could be used as potential targeting carrier for delivering anticancer drug to the lungs with the minimal side effects.

    A follow-up 18F-fluorodeoxyglucose ({sup 18}F-FDG) PET/CT scan of a 57-year-old asymptomatic male who had undergone total thyroidectomy for thyroid cancer revealed a 5.0 x 4.0-cm, well-defined, ovoid-shaped mass around the left adrenal gland without definite FDG uptake. On the adrenal CT scan, the left paraadrenal tumor showed high attenuation on the precontrast scan without enhancement. The average Hounsfield unit (HU) was 58.1 on the precontrast scan and 58.4 on the postcontrast scan. The patient underwent laparoscopic adrenalectomy for resection of the left paraadrenal tumor. The final histopathologic examination revealed a bronchogenic cyst. Although retroperitoneal bronchogenic cysts are rare, they should be considered in the differential diagnosis of retroperitoneal cystic tumors. The preoperative diagnosis is difficult, but a contrast-enhanced CT scan or {sup 18}F-FDG PET/CT scan may be useful for differentiating hyperattenuated cysts from other soft tissue masses.

    The present case includes the radiographic, myelographic and computed tomographic appearances of large, perineurial, Tarlov cysts. While the findings in this case are typical, the features on plain film examination can suggest other, more serious differential diagnostic considerations. The myelographic and CT patterns are diagnostic, if intrathecal contrast fills the cyst as in this instance. The case was complicated by the finding of a large lytic lesion in the right ilium which on biopsy proved to be metastasis from a bronchogenic carcinoma. (orig./GDG).

    Full Text Available O cisto broncogênico, apesar da aparência pouco ominosa como opacidade de contornos precisos no mediastino, tem potencial não desprezível para complicar. Relatamos um caso de complicação grave em um paciente de 28 anos com queixa de dor epigástrica irradiada para o dorso, e radiografia de tórax demonstrando massa bem delimitada no mediastino posterior e inferior à direita. Em cinco dias evoluiu para sepse decorrente de mediastinite e empiema pleural à esquerda. O paciente necessitou ser submetido a toracotomia esquerda para descorticação pulmonar precoce e desbridamento do mediastino e, num segundo tempo com intervalo de uma semana, a toracotomia direita para ressecção do cisto mediastinal infectado. Este caso enfatiza a indicação sensata de ressecção dos cistos mediastinais mesmo na apresentação assintomática, face ao risco inerente de complicações.Notwithstanding its hardly ominous appearance as a mediastinal opaque mass with precise contours, the bronchogenic cyst has a significant potential for complications. We report a case of severe complication in a 28-year-old male presenting with epigastric pain irradiating to the back and at chest X-ray disclosing a well delimited mass in the posterior-inferior right side of the mediastinum. On the fifth day after onset of the symptoms, the patient developed sepsis resulting from mediastinitis and left pleural empyema. The patient was submitted to a left thoracotomy for lung decortication and mediastinal drainage and, after one week interval at a second stage, to a right thoracotomy for resection of the infected mediastinal cyst. In view of the inherent risk of omplications, mediastinal cyst resection is strongly recommended, even in cases of asymptomatic presentation.

Methods A neck mass of a patient was diagnosed as bronchogenic cyst by histological examination. The clinical data were analyzed and literatures were reviewed. Results The patient received a cervial cyst resection and a bronchogenic cyst was identified by pathological examination. The patient had an uneventful recovery without recurrence after 1 year follow-up. Conclusion Cervical ectopic bronchogenic cyst is extremely rare, moreover it has no distinctive characteristics in clinical symptoms and image examinations, so that the diagnosis still depends on the pathology. The first choice of treatment is surgical resection, and the prognosis is effective and favorable.

    To verify the accuracy of the absorbed doses D calculated by a TPS Cadplan for a bronchogenic treatment (in an Alderson-Rando phantom) are chosen ten points with the following D's and localizations. Point 1, posterior position on the left edge with 136.4 Gy. Points: 2, 3 and 4 in the left lung with 104.9, 104.3 and 105.8 Gy, respectively; points 5 and 6 at the mediastinum with 192.4 and 173.5 Gy; points 7, 8 and 9 in the right lung with 105.8, 104.2 and 104.7 Gy, and 10 at posterior position on right edge with 143.7 Gy. IAEA type capsules with TLD 100 powder are placed, planned and irradiated. The evaluation of the absorbed dose is carried out a curve of calibration for the LiF response (nC) {sup vs} {sup DW}, to several cavity theories. The traceability for the DW is obtained with a secondary standard calibrated at the NRC (Canada). The dosimetric properties for the materials considered are determined from the Hounsfield numbers reported by the TPS. The stopping power ratios are calculated for nominal spectrum to 6 MV photons. The percent variations among the planned and determined D in all the cases they are < ± 3%.

    Objective: To evaluate the correlation of the quantifiable parameters of blood flow pattern derived with dynamic CT in solitary bronchogenic adenocarcinoma (SBA). Methods: 46 patients with solitary bronchogenic adenocarcinomas (SBA) (diameter ≤ 4 cm) underwent multi-location dynamic contrast material-enhanced (nonionic contrast material was administrated via the antecubital vein at a rate of 4 mL/s by using an autoinjector 90 mL, 4 × 5 mm or 4 × 2.5 mm scanning mode with stable table were performed) serial CT. Precontrast and postcontrast attenuation on every scan was recorded. Perfusion (PBA), peak height (PHBA), ratio of peak height of the SPN to that of the aorta (BA-to-A ratio) and mean transit time (MTT) were calculated. The correlation between peak height of the aorta (PHA) and parameters of the SBA (PHBA, BA-to-A ratio, PBA, and MTT) and those among parameters of the SBA were assessed by means of linear regression analysis. Regression equation among parameters of the SBA were obtain by means of stepwise regression. Results: The correlation between the SBA peak height (PHBA, 36.78 HU ± 12.02) and the aortic peak height (PHA) was significant (r = 0.506, P < 0.0001). No significant cor relation was found between the BA-to-A peak height ratio (15.33% ± 4.55) and the aortic peak height (r = 0.130, P = 0.388 >0.05) as it was between the SBA perfusion (PBA, 31.86 mL/min/100 g ± 9.74) and the aortic peak height (r = 0.049, P = 0.749 > 0.05). The SBA perfusion correlated with the PHBA and the BA-to-A peak height ratio (r = 0.394, P = 0.007 < 0.05; r = 0.407, P = 0.005 < 0.05). The PHBA correlated positively with the BA-to-A peak height ratio (r = 0.781, P < 0.0001). Mean transit time was 14.84 s ± 5.52. PBA = 18.500 + 0.872 × BA-to-A ratio. BA-to-A ratio = 4.467 + 0.295 × PHBA. Conclusion: The linear correlation between the SBA perfusion and BA-to-A ratio and that between BA-to-A ratio and PHBA can be expressed by equation.It is possible to

    Small bowel metastases from primary carcinoma of the lung are very uncommon and occur usually in patients with terminal stage disease. These metastases are usually asymptomatic, but may present as perforation,obstruction, malabsorption, or hemorrhage. Hemorrhage as a first presentation of small bowel metastases is extremely rare and is related to very poor patient survival. We describe a case of a 61- year old patient with primary adenocarcinoma of the lung, presenting with melena as the first manifestation of small bowel metastasis. Both primary tumor and metastatic lesions were diagnosed almost simultaneously. Upper gastrointestinal endoscopy performed with a colonoscope revealed active bleeding from a metastatic tumor involving the duodenum and the proximal jejunum.Histological examination and immunohistochemical staining of the biopsy specimen strongly supported the diagnosis of metastatic lung adenocarcinoma, suggesting that small bowel metastases from primary carcinoma of the lung occur usually in patients with terminal disease and rarely produce symptoms. Gastrointestinal bleeding from metastatic small intestinal lesions should be included in the differential diagnosis of gastrointestinal blood loss in a patient with a known bronchogenic tumor.

    Full Text Available Small cell neuroendocrine carcinoma (SNEC is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach. In this paper, we report a patient presented with left-sided facial swelling, and the histopathologic examination confirmed primary SNEC of left sinonasal tract. The tumor involved multiple paranasal sinuses with invasion into the left orbit and left infratemporal fossa and metastasized to cervical lymph nodes and bone. The patient encountered devastating outcome in spite of optimal medical management and treatment with palliative chemotherapy highlighting the necessity for further research of primary SNEC of head and neck.

    Squamoid eccrine ductal carcinoma is an eccrine carcinoma subtype, and only twelve cases have been reported until now. It is a rare tumor and its histopathological diagnosis is difficult. Almost half of patients are misdiagnosed as squamous cell carcinoma by the incisional biopsy. We report the thirteenth case of squamoid eccrine ductal carcinoma. Female patient, 72 years old, in the last 6 months presenting erythematous, keratotic and ulcerated papules on the nose. The incisional biopsy diagnosed squamoid eccrine ductal carcinoma. After excision, histopathology revealed positive margins. A wideningmargins surgery and grafting were performed, which again resulted in positive margins. The patient was then referred for radiotherapy. After 25 sessions, the injury reappeared. After another surgery, although the intraoperative biopsy showed free surgical margins, the product of resection revealed persistent lesion. Distinction between squamoid eccrine ductal carcinoma and squamous cell carcinoma is important because of the more aggressive nature of the first, which requires wider margins surgery to avoid recurrence.

    2004-01-01

    Objective: To investigate the clinicopathologic features and diagnostic criteria of urachal carcinoma in the bladder.Methods: Seven cases of urachal carcinoma in the bladder were analyzed retrospectively. Results: All the tumors were found locating in the dome of bladder. Of them, 4 were mucinous adenocarcinoma, one was well differentiated papillary enteric adenocarcinoma, one was well differentiated squamous carcinoma, and one was neuroendocrine carcinoma. Cystomorphous urachal remnants were found in 4 cases. The main complaint was hematuria and all patients underwent partial excision of bladder and urachus. Conclusion: Mucinous adenocarcinoma is the main histo-pathological type, and cystomorphous urachal remnants are often accompanied with urachal carcinoma in the bladder. The key diagnostic criteria of urachal carcinoma in bladder are site and histopathology. And to examine the specimens carefully to find the urachal remnants is important.

    Full Text Available Abstract Background Ocular sebaceous carcinoma can masquerade as benign lesions resulting in delay of diagnosis. Early recognition is even more difficult in young patients where the disease rarely occurs. Here, we provide a clinicopathological correlation of ocular sebaceous carcinoma in a young individual lacking history of hereditary cancer or immunosuppression. Findings A detailed histopathological study including p53 DNA sequencing was performed on an aggressive sebaceous carcinoma presenting in a healthy 32 year-old Caucasian woman. She had no history of retinoblastoma, evidence for a hereditary cancer syndrome, or radiation therapy. However, she potentially was at risk for excessive UV light exposure. A detailed review of the literature is also provided. A moderately well differentiated sebaceous carcinoma was established histopathologically arising from the meibomian gland of the upper eyelid. In most areas, the cytoplasm contained small but distinct Oil-red-O positive vacuoles. Direct sequencing of p53 identified a G:C→A:T mutation at a dipyrimidine site. The mutation results in substitution of arginine for the highly conserved glycine at residue 199 located at the p53 dimer-dimer interface. Energy minimization structural modeling predicts that G199R will neutralize negative charges contributed by nearby inter- and intramonomeric glutamate residues. Discussion This study points to the importance of recognizing that sebaceous carcinoma can occur in young patients with no evidence for hereditary cancer risk or radiation therapy. The G199R substitution is anticipated to alter the stability of the p53 tetrameric complex. The role of UV light in the etiology of sebaceous carcinoma deserves further study. Our findings, taken together with those of others, suggest that different environmental factors could lead to the development of sebaceous carcinoma in different patients.

    Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or viral wart. These factors, together with a general lack of awareness of this disease among physicians, often result in delayed diagnosis. Therefore, it is underdiagnosed, with few reports in the literature. The authors present a case of a man with a diagnosis of subungual squamous cell carcinoma in the hallux, without bone involvement, which was submitted to the appropriate surgical treatment.

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

  3. Primary fallopian tube carcinoma

    Directory of Open Access Journals (Sweden)

    Mladenović-Segedi Ljiljana

    2009-01-01

    Full Text Available Introduction. Primary fallopian tube carcinoma is extremely rare, making 0.3-1.6% of all female genital tract malignancies. Although the etymology of this tumor is unknown, it is suggested to be associated with chronic tubal inflammation, infertility, tuberculous salpingitis and tubal endometriosis. High parity is considered to be protective. Cytogenetic studies show the disease to be associated with over expression of p53, HER2/neu and c-myb. There is also some evidence that BRCA1 and BRCA2 mutations have a role in umorogeneis. Clinical features. The most prevailing symptoms with fallopian tube carcinoma are abdominal pain, abnormal vaginal discharge/bleeding and the most common finding is an adnexal mass. In many patients, fallopian tube carcinoma is asymptomatic. Diagnosis. Due to its rarity, preoperative diagnosis of primary fallopian tube carcinoma is rarely made. It is usually misdiagnosed as ovarian carcinoma, tuboovarian abscess or ectopic pregnancy. Sonographic features of the tumor are non-specific and include the presence of a fluid-filled adnexal structure with a significant solid component, a sausage-shaped mass, a cystic mass with papillary projections within, a cystic mass with cog wheel appearance and an ovoid-shaped structure containing an incomplete separation and a highly vascular solid nodule. More than 80% of patients have elevated pretreatment serum CA-125 levels, which is useful in follow-up after the definite treatment. Treatment. The treatment approach is similar to that of ovarian carcinoma, and includes total abdominal hysterectomy and bilateral salpingo-oophorectomy. Staging is followed with chemotherapy.

    Full Text Available Adrenal sarcomatoid carcinomas are extremely rare tumors presenting with extensive locoregional spread at the time of diagnosis. Patients succumb to metastases within a couple of months. As a result, very few cases are reported in the literature until now. We present a case of a 62-year old female with non-functional sarcomatoid carcinoma of the right adrenal gland. There was no radiological evidence of locoregional metastases. Patient underwent right adrenalectomy. Follow up after 3 months showed para-aortic lymphadenopathy and similar left adrenal mass on computed tomography. Patient refused further treatment and succumbed to the disease. A brief case report with review of literature is presented.

    Full Text Available Urachal carcinoma is a rare neoplasm, which accounts for only 0.5–2% of bladder malignancies, and arises from a remnant of the fetal genitourinary tract. A 46-year-old woman presented with a history of pelvic pain and frequent daytime urination. Ultrasound (US, computed tomography (CT, and magnetic resonance (MR demonstrated a supravesical heterogeneous mass with calcifications. The patient underwent a partial cystectomy with en-bloc resection of the mass and histopathological examination revealed the diagnosis of urachal adenocarcinoma. Urachal carcinomas are usually associated with poor prognosis and early diagnosis is fundamental. CT and MR are useful to correctly diagnose and preoperatively staging.

    A few signaling pathways are driving the growth of hepatocellular carcinoma. Each of these pathways possesses negative regulators. These enzymes, which normally suppress unchecked cell proliferation, are circumvented in the oncogenic process, either the over-activity of oncogenes is sufficient to annihilate the activity of tumor suppressors or tumor suppressors have been rendered ineffective. The loss of several key tumor suppressors has been described in hepatocellular carcinoma. Here, we systematically review the evidence implicating tumor suppressors in the development of hepatocellular carcinoma.

    2012-02-01

    Thyroid carcinoma is the most commonly diagnosed endocrine malignancy. Its incidence is currently rising worldwide. The discovery of genetic mutations associated with the development of thyroid cancer, such as BRAF and RET, has lead to the development of new drugs which target the pathways which they influence. Despite recent advances, the prognosis of anaplastic thyroid carcinoma is still unfavourable. In this review we look at emerging novel therapies for the treatment of well-differentiated and medullary thyroid carcinoma, and advances and future directions in the management of anaplastic thyroid carcinoma.

    AIM: To review the characteristics of esophageal carcinoma in recent 30 years in the epidemiological investigation.METHODS: A total of 1 520 cases of esophageal carcinoma in the First Affiliated Hospital of Zhejiang University Medical College admitted from 1970 until now were reviewed. Their age, gender, position of carcinoma and histological type were analyzed.RESULTS: The morbidity of esophageal carcinoma was increasing during the observation period. Compared with the 1970s (9.5%), the ratio of adenocarcinoma significantly increased after the 1980s (19.1%). The difference was significant (P≤0.05).CONCLUSION: The morbidity of esophageal adenocarcinoma was increasing and advanced clinical study should be strengthened.

    2012-07-01

    Vismodegib is a novel, small-molecule inhibitor of smoothened, a key component of the hedgehog signaling pathway. Increased hedgehog pathway signaling is critical in the development of hereditary and spontaneous basal cell carcinomas of the skin, and has been implicated in the development of a number of other tumors. In preclinical models, vismodegib demonstrated potent antitumor activity in hedgehog-dependent tumors, particularly basal cell carcinomas. Clinically, phase I and II studies showed dramatic anticancer activity in patients with advanced basal cell carcinomas. In January 2012, vismodegib was approved by the FDA for the treatment of unresectable or metastatic basal cell carcinomas of the skin.

    Objective: To evaluate factors for prognosis of cervical carcinoma. Methods: Expressions of mn23- HI, erbB3 and erbB4 were examined by immunohistochemical staining. The apoptosis was detected in situ by the TdT mediated duip-biotin nick end-labeling (TUNEL) technique. Mitotic cell were counted by HE dyeing. Results: FIGO stage and lymph node metastasis were the most important factors for evaluating prognosis in adenocarcinoma or squamous cell carcinoma. AI/MI was positively correlated with 5-year survival of cervical carcinoma. Positive expression of nm23-H1 combed with negative expression of erbB4 [nm23-H1(+)/erbB4(-)] predicted good prognosis for adeno-carcinoma. In multivariable Cox regression analysis, only FIGO stage and AI/MI were into equation. Conclusion: FIGO stage and AI/MI were independent evaluating parameter for adenocarcinoma or squamous cell carcinoma.

    1984-05-01

    A 73-year-old man had a limbal nodule that, on histopathologic examination, proved to be mucoepidermoid carcinoma of the conjunctiva. Despite radiation therapy and extensive corneoscleral lamellar resection, widespread invasion of the lids and orbit ultimately led to exenteration. Although mucoepidermoid carcinoma of the conjunctiva resembles squamous cell carcinoma clinically and histopathologically, it pursues a more rapid and destructive clinical course. Intraepithelial invasion often leads to tumor involvement of conjunctiva and skin that seem normal on clinical examination. Special stains and a high level of suspicion are required for diagnosis of mucoepidermoid carcinoma of the conjunctiva, and proper initial management demands more aggressive surgical resection than is usually indicated for squamous cell carcinoma.

    Full Text Available Pancreatic cancer patients present late in their course and surgical resection as a modality of treatment is of limited value. Majority develop loco-regional failure and distant metastasis, therefore, adjuvant therapy comprising of radiotherapy and chemotherapy are useful treatment options to achieve higher loco-regional control. Specialized irradiation techniques like intra-operative radiotherapy that help to increase the total tumor dose have been used, however, controvertible survival benefit was observed. Various studies have shown improved median and overall survival with chemoradiotherapy for advanced unresectable pancreatic carcinoma. The role of new agents such as topoisomerase I inhibitors also needs further clinical investigations.

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

    2009-03-01

    Squamous cell carcinoma (SCC) is a relatively common, malignant neoplasm of dogs and cats that can arise in a variety of locations. The gross appearance of SCC can be variable and nonspecific, so definitive diagnosis requires microscopic examination of the tissue (cytology or histology). Several treatment modalities exist, but surgical excision, if possible, is regarded as the best treatment option. Early diagnosis and treatment of SCC are key because small, early-stage tumors are the most amenable to treatment and carry the best prognosis.

  4. Etiopathogenesis of Differentiated Thyroid Carcinomas

    Tanja Makazlieva

    2016-08-01

    Full Text Available INTRODUCTION: Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiated anaplastic thyroid carcinoma. There are increasing numbers of epidemiological studies and publications that have suggested increased incidence rate of thyroid carcinomas. We have read, analysed and compare available reviews and original articles investigating different etiological factors in the development of thyroid carcinomas through Google Scholar and PubMed Database. DISCUSSION: Aetiology involved in the development of thyroid carcinomas is multifactorial and includes external influences, as well as constitutional predispositions and genetic etiological factors. The actual effect of environmental and constitutional factors is on promoting genetic and epigenetic alterations which result in cell proliferation and oncogenesis. Until now are identified numerous genetic alterations, assumed to have an important role in oncogenesis, with MAPK and PI3K-AKT as crucial signalling networks regulating growth, proliferation, differentiation and cell survival/apoptosis. CONCLUSION: This new molecular insight could have a crucial impact on diagnosis and also on improving and selecting an appropriate treatment to the patients with thyroid malignancies.

Immunohistochemical analysis of carcinomas revealed a strong vitronectin accumulation in extracellular matrix (ECM) around some cancer cell clusters...... and in the subendothelial area of some blood vessels. In normal tissue, vitronectin had a homogeneous periductal occurrence, with local accumulation much lower than that in the carcinomas. Using a new solid phase radioligand assay, the vitronectin concentrations of extracts of carcinomas and normal breast tissue were...... determined and found to be indistinguishable. Comparison of the vitronectin and the hemoglobin concentrations of the extracts showed that their vitronectin content was not derived from blood contamination. Vitronectin mRNA was undetectable in both carcinomas and normal tissue. We conclude that vitronectin...

  7. Hepatocellular Carcinoma (HCC)

    Science.gov (United States)

    Helmberger, Thomas K.

    Hepatocellular carcinoma (HCC) is considered to be one of the most common malignancies worldwide, and the most common one in Africa and Asia. Over the last decade, a rising incidence of up to 10-15/100,000 per population has been seen in the Western world, with an estimate of 250,000 deaths and more than a million worldwide per year. By the year 2010, the World Health Organization expects that HCC will be the leading cause of cancer mortality surpassing lung cancer. This increasing incidence is most likely related to an increasing prevalence of chronic hepatitis C (HC) and B (HB) virus infections and other diseases inducing chronic inflammation (Befeler and Di Bisceglie 2002; Llovet et al. 2003).

    2004-01-01

    Despite advances in surgical and nonsurgical treatment, overall survival rates for patients who have hypopharyngeal carcinoma have not improved,and this disease still has a poor prognosis. The best results are obtained with multimodality therapy. but at best, two thirds of patients are palliated rather than cured of disease. Radical surgery with postoperative radiation therapy remains the standard of care. Organ preservation strategies have not been as successful in hypopharyngeal cancer as for cancers of other head and neck sites. Chemoradiation is an effective alternative method of aggressive treatment but may be associated with significant dysfunction of the end organ when preservation is possible. Because of poor long-term survival rates, local control remains the most important factor in planning treatment, to provide meaningful palliation and best possible quality of life.

    1990 to 2005 were identified. Histological slides were reviewed, and data concerning demographics, tumour site, clinical stage, treatment profiles and follow-up were retrieved. Survival estimates and prognostic factors were evaluated by comparing Kaplan-Meier plots using the Mantel-Haenszel log......-rank test. RESULTS: Salivary duct carcinoma showed an incidence of 0.04/100.000 inhabitants/year. Distant recurrence was seen in 52% of patients. Five-year overall survival, disease-specific survival and recurrence-free survival were 32%, 42% and 35%, respectively. Univariate analyses suggested that overall...... stage (III/IV) and vascular invasion have a negative impact on all survival measures. Involved resection margins correlated with a poorer overall survival and disease-specific survival, whereas adjuvant radiotherapy improved overall survival and recurrence-free survival.

    The completely assembled human genome has made it possible for modern medicine to step into an era rich in genetic information and high-throughput genomic analysis. These novel and readily available genetic resources and analytical tools may be the key to unravel the molecular basis of hepatocellular carcinoma (HCC). Moreover, since an efficient treatment for this disease is lacking, further understanding of the genetic background of HCC will be crucial in order to develop new therapies aimed at selected targets. We report on the current status and recent developments in HCC genetics. Special emphasis is given to the genetics and regulation of major signalling pathways involved in HCC such as p53, Wntsignalling, TGFβ, Ras, and Rb pathways. Furthermore, we describe the influence of chromosomal aberrations as well as of DNA methylation. Finally, we report on the rapidly developing field of genomic expression profiling in HCC, mainly by microarray analysis.

    The optimal surgical strategy for hepatocellular carcinoma (HCC) is under active debate. Bio-markers of the liver functional reserve as well as volumetric analysis of the future liver remnant are essential for safe liver resection of HCC. The present algorithms applied to surgical strategies for HCC are not ideal because many patients who could potentially undergo safe resection are deemed liver transplant candidates in Western countries, whereas the opposite is the case in Eastern countries. In addition, there is too much focus on expanded criteria for patients with HCC to undergo liver transplantation. The transplantation benefit for patients with HCC should be considered based not only on the individual's benefit, but also on the effect of other patients waiting for LT for other indications.

    Salivary gland myoepithelial carcinoma (MC) or malignant myoepithelioma is a rare entity. MC usually presents as a slow-growing painless mass arising in the parotid gland, but may involve other salivary glands. This tumour may be particularly locally aggressive, but its clinical and biological features are not yet fully understood. MC may arise from pre-existing benign lesions, such as pleomorphic adenomas or benign myoepitheliomas, or may arise de novo. It usually affects patients over 50 years old, with no gender preference. Because it is often asymptomatic, the presentation and diagnosis can be delayed by months, even years. The current WHO classification considers MC to be an intermediate- to high-grade malignancy. Other published data suggest it is likely to be a high-grade neoplasm, consistent with its aggressive behaviour. Its epidemiology, histopathological features, immunohistochemical profile, clinical behaviour and optimal management are not well understood. Following review of the current literature we aim to address these.

    Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine carcinoma of the skin. Although it is 40 times less common than malignant melanoma, its mortality is much higher compared to melanoma. From 1986 to 2001 there was rapidly increasing incidence in reported cases of MCC, with a tripling in the rate over this 15-year period. The vast majority of MCC presents on sun-exposed skin. The head and neck area is the most common site of tumor occurrence. We present 70-year old female patient with painless red-colored nodule, size 2 x 2 x 2 cm on the dorsal side of mid left forearm. The surgical excision with negative margins was performed, and pathohistological analysis confirmed Merkel cell carcinoma. Sentinel lymph node biopsy was negative. In conclusion, as MCC is a very aggressive rare skin carcinoma with lethal outcome, it should be mandatory to perform biopsies of any suspected skin lesion.

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    Full Text Available Abstract Objectives The aim of this study was to present a rare neoplasm, Primary myoepithelial carcinoma arising from the palate, and to review its diagnostic criteria, pathologic and clinical characteristics, treatment options and prognosis. Clinical Presentation and Intervention Myoepitheliomas are tumors arising from myoepithelial cells mainly or exclusively. Myoepitheliomas mostly occur in salivary glands, as well as in breast, skin, and lung. Case of myoepitheliomas in palate has rarely been reported. Myoepithelial carcinoma is malignant counterpart of myoepitheliomas. Adenomyoepithelioma is also a different disease from myoepitheliaomas. Immunohistochemically, tumor cells of myoepithelial carcinoma express not only epithelial markers such as cytokeratin, epithelial membrane antigen (EMA, but also markers of smooth muscle origin such as calponin. The immunohistochemical criteria of myoepithelial differentiation are double positive for both cytokeratins and one or more myoepithelial immunomarkers (i.e., S-100 protein, calponin, p63, GFAP, maspin, and actins. Myoepithelial carcinomas of salivary and breast demonstrate copy number gains and gene deletion. The overall prognosis of myoepithelial carcinoma is poor. There is rarely recurrence or metastasis in benign myoepithelial tumors. Complete excision with tumor-free margin is always the preferred treatment, while local radiation therapy and chemotherapy are suggestive treatment options. Here, a rare case of myoepithelial carcinoma arising from the palate has been described and discussed for the treatment and outcome. Pathological and clinical characters of myoepitheliomas are also compared and discussed. Conclusion The case report serves to increase awareness and improve the index of diagnosis and treatment of myoepitheliomas.

    We reclassified 720 nonmedullary invasive thyroid carcinomas diagnosed and treated between 1975 and 1993. Twenty-seven cases met the criteria of insular carcinoma and 29 cases those of widely invasive follicular carcinoma. Comparison of these histotypes with respect to pathologic stage and overall, relative, and visceral metastasis-free survival showed a significant association between histotype and pT and pN categories. In particular, pT4 (p AAA transversion at codon 61 of the N-RAS gene in insular carcinoma. These findings suggest that insular carcinoma represents a de novo entity distinct from widely invasive follicular carcinoma, that widely invasive follicular carcinoma has biologic characteristics more consistent with poorly differentiated than well-differentiated carcinomas, and that both insular carcinoma and widely invasive follicular carcinoma share similar molecular alterations.

    Hepatocellular carcinoma (HCC) is primarily a malignancyof the liver, advancing from a damaged, cirrhoticliver to HCC. Globally, HCC is the sixth most prevalentcancer and the third-most prevalent reason for neoplasticdisease-related deaths. A diverse array ofinfiltrating immunocytes regulates the developmentand progression of HCC, as is the case in many othercancers. An understanding of the various immunecomponents during HCC becomes necessary so thatnovel therapeutic strategies can be designed to combatthe disease. A dysregulated immune system (includingchanges in the number and/or function of immunecells, cytokine levels, and the expression of inhibitoryreceptors or their ligands) plays a key role in thedevelopment of HCC. Alterations in either the innateor adaptive arm of the immune system and cross-talkbetween them make the immune system tolerant totumors, leading to disease progression. In this review,we have discussed the status and roles of variousimmune effector cells (e.g. , dendritic cells, natural killercells, macrophages, and T cells), their cytokine profile,and the chemokine-receptor axis in promoting orimpeding HCC.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    2017-01-01

    Basosquamous carcinoma (BsC) is a controversial entity and both a diagnostic and therapeutic challenge. BsC has mixed histopathological characteristics of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BCC and SCC display characteristic histopathology and behaviour; on the other hand, BsC is a rare tumour, which has variable morphology and displays less predictable behaviour. An early diagnosis of BsC is important due to the particularly aggressive nature of the tumour, the increased likelihood of recurrence and the potential for metastasis. Here, we present a case of BsC presenting as an extensive ulcer on the back. The case highlights the aggressive nature of the tumour and variation in appearance. It is important for all clinicians to be aware of this diagnosis so that the urgency of adequate biopsy in specialist clinics is not underestimated. PMID:28058108

    The authors studied 80 hepatocellular carcinomas from three continents for p53 gene (TP53) mutations and hepatitis B virus (HBV) sequences. p53 mutations were frequent in tumors from Mozambique but not in tumors from South Africa, China, and Germany. Independent of geographic origin, most tumors were positive for HBV sequences. X gene coding sequences of HBV were detected in 78% of tumors, whereas viral sequences in the surface antigen- and core antigen-encoding regions were present in less than 35% of tumors. These observations indicate that hepatocellular carcinomas are genetically heterogeneous. Mozambican-types of hepatocellular carcinomas are characterized by a high incidence of p53 mutations related to aflatoxins. In other tumors, the rarity of p53 mutations combined with the frequent presence of viral X gene coding sequences suggests a possible interference of HBV with the wild-type p53 function.

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors.

    We have adopted for the follow up of the differentiated thyroid carcinomas in adult cases, a protocol of control which is at the same time strict and not very constraining for the patient and which is based on two types of investigations. Most of your patients have been, at first, submitted for a total thyroidectomy which is followed with one or many therapeutic doses of 3700 MBq (100 mCi) of 131-Iodine and that to destroy thewhole of the thyroid tissue. The patients are then reexamined every six months and are submitted for a T4 opotherapeutic treatment the balance of a general check-up which includes a delicate clinic control, radiologic exam and biological exam, a general control of thyroid hormones, of the T.S.H. and the thyroglobulin and the antithyroglobulin antibodies. In case of any doubt, the balance sheet must be stopped and the patient which is suspected of having Iodine desaturation is submitted for a new general clinic and biologic check-up, which is accompanied with a total scanning after oral administration of 185 mBq (5 mCi) 131-Iodine. If this general check-up shows any active nodul, another therapeutic decision is taken which is often based on an new carcinologic dose of 131-Iodine. This treatment is always followed with a post therapeutic scanning 2 and 5 days later and than another new general check-up three months later to judge the efficiency of the treatment, and during this time the patient is compensed with a LT3.

    Epidemiological studies showed that incidence of colon carcinoma is increased in the world. There are many difficulties to inhibit colon carcinoma because the causes of inducing colon carcinoma were various and interactive each other. Previous evidence supported the balance of the colonic microflora was critical in inhibiting colon carcinoma and the protection by colonic microflora could be improved by ingesting lactobacilli. Therefore, the biological functions and anticancer effects of lactobacilli attract attention of researchers. In this review we discussed the causes of colon carcinoma; the anticancer mechanisms of lactobacilli on the basis of our own studies. Eventually, we summarized the effects of anticancer of different components and metabolic products extracted from lactobacilli.

    Full Text Available Tubulocystic renal cell carcinoma (TCRCC is a rare variant of renal cell carcinoma, which has distinct histology but there is some controversy about its association with papillary renal cell carcinoma (PRCC and cell of origin in literature. We report an 18-year-old girl with the rare TCRCC of kidney associated with PRCC with metastases to the para-aortic nodes. The patient presented with hematuria and a right renal mass with enlarged regional nodes for which a radical nephrectomy with retroperitoneal lymph node dissection was done. On gross examination, a solid cystic lesion involving the lower pole and middle pole of the kidney measuring 12x9x9 cm was seen along with an additional cystic lesion in upper pole of kidney. Microscopically the main tumor showed the typical histology of a tubulocystic carcinoma with multiple cysts filled with secretions lined by variably flattened epithelium with hobnailing of cells. The mass in the upper pole was a high-grade PRCC and the nodal metastases had morphology similar to this component. To conclude, at least a small but definite subset of TCRCC is associated with PRCC, and cases associated with PRCC do seem to have a higher propensity for nodal metastasis as in the case we report.

    Objective:To investigate the significance of telomerase activity in breast carcinoma with its respect to axillary lymph node status. Methods: Telomerase activity was analyzed in 88 breast carcinomas and 16benign breast lesions, using polymerase chain reaction (PCR)-based telomeric repeat amplification protocol (TRAP) assay. Results: Telomerase activity was detected in 75 (85%) of 88 breast carcinomas (including three breast carcinomas in situ which were all positive for telomerase activity), whereas in benign breast lesions analyzed only 2(12.5%) of 16 cases were positive for telomerase activity. The difference between the two groups was statistically significant (P<0.001). Besides,telomerase activity was expressed significantly higher in node-positive breast carcinoma (93%) than in nodenegative ones (77%) (P<0.05). Conclusion: Our results suggest that telomerase activation plays an important role during breast carcinoma development. It is possible that this enzyme may serve as an early indication of breast carcinoma.

    Androgen-independent, human prostate carcinoma cells (DU145) develop into solid, carcinomatous xenotransplants on the diaphragm of nu/nu mice. Tumors encompass at least two poorly differentiated cell types: a rapidly dividing, eosinophilic cell comprises the main cell population and a few, but large basophilic cells able to invade the peritoneal stroma, the muscular tissue, lymph vessels. Poor cell contacts, intracytoplasmic lumina, and signet cells are noted. Lysosomal activities are reflected by entoses and programmed cell deaths forming cribriform carcinomas. In large tumors, degraded cells may align with others to facilitate formation of blood supply routes. Malignant cells would spread via ascites and through lymphatics.

  3. Cyclooxygenases in hepatocellular carcinoma

    2006-01-01

    Many epidemiological studies demonstrate that treatment with non-steroidal anti-inflammatory drugs (NSAIDs) reduce the incidence and mortality of certain malignancies, especially gastrointestinal cancer. The cyclooxygenase (COX) enzymes are well-known targets of NSAIDs. However, conventional NSAIDs nonselectively inhibit both the constitutive form COX-1, and the inducible form COX-2. Recent evidence indicates that COX-2 is an important molecular target for anticancer therapies. Its expression is undetectable in most normal tissues, and is highly induced by proinflammatory cytokines, mitogens, tumor promoters and growth factors. It is now well-established that COX-2 is chronically overexpressed in many premalignant, malignant, and metastastic cancers, including hepatocellular carcinoma (HCC). Overexpression of COX-2 in patients with HCC is generally higher in welldifferentiated HCCs compared with less-differentiated HCCs or histologically normal liver, suggesting that COX-2 may be involved in the early stages of hepatocarcinogenesis, and increased expression of COX-2 in noncancerous liver tissue has been significantly associated with shorter disease-free survival in patients with HCC.In tumors, overexpression of COX-2 leads to an increase in prostaglandin (PG) levels, which affect many mechanisms involved in carcinogenesis, such as angiogenesis, inhibition of apoptosis, stimulation of cell growth as well as the invasiveness and metastatic potential of tumor ceils. The availability of novel agents that selectively inhibit COX-2 (COXIB), has contributed to shedding light on the role of this molecule. Experimental studies on animal models of liver cancer have shown that NSAIDs, including both selective and non-selective COX-2 inhibitors, exert chemopreventive as well as therapeutic effects. However, the key mechanism by which COX-2 inhibitors affect HCC cell growth is as yet not fully understood. Increasing evidence suggests the involvement of molecular targets other

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    AIM: To analyze expression of ATP7B in gastric cardiac adenocarcinomas, its clinicopathologic significance, in comparison with distal gastric adenocarcinomas.METHODS: Immunohistochemical avidin-biotin peroxidase complex method was applied to detect the expression of ATP7B in 49 cases of cardiac carcinomas,the corresponding adjacent non-neoplastic epithelium and 55 cases of distal gastric carcinomas.RESULTS: The proportion of ATP7B positive samples in gastric cardiac carcinomas (51.0%, 25 of 49) was significantly higher than that in the corresponding adjacent non-neoplastic epithelium (22.4%, 11 of 49)(P = 0.003). ATP7B expression in poorly differentiated gastric cardiac carcinomas was significantly higher than that in well/moderately differentiated gastric cardiac carcinomas (P = 0.030). ATP7B expression in gastric cardiac carcinomas was independent of age, tumor size, nodal stage and metastasis status. ATP7B protein was detected in 30.9% (17/55 cases) of distal gastric carcinomas, markedly lower than that in gastric cardiac carcinomas (P = 0.037).CONCLUSION: ATP7B protein is frequently overexpressed in gastric cardiac carcinomas, and correlated with the differentiation of cardiac carcinoma. ATP7B expression in gastric cardiac carcinomas is significantly higher than that in distal gastric carcinomas, which might partially explain the difference of chemotherapy response and prognosis between these two gastric carcinomas.

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais. A prevenção do carcinoma basocelular se baseia no conhecimento de fatores de risco, no diagnóstico e tratamento precoces e na adoção de medidas específicas, principalmente, nas populações susceptíveis. Os autores apresentam uma revisão da epidemiologia do carcinoma basocelular.Basal cell carcinoma is the most common malignant neoplasm in humans and its incidence has increased over the last decades. Its high frequency significantly burdens the health system, making the disease a public health issue.

    Full Text Available Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion. Computed tomography scan of abdomen and pelvis showed no residual disease or any abdominal lymphadenopathy. Mammography of both breast were normal. Bilateral axillary nodes were noted. Guided fine needle aspiration cytology (FNAC and biopsy of ovarian carcinoma to axillary node is a rare event. Its recogn done. Cytomorphology revealed poorly differentiated carcinoma, compatible to that of primary ovarian tumor. Thus, metastatic carcinoma to axillary node from ovary was confirmed. This case illustrates a rare metastatic presentation of ovarian carcinoma and unequivocal role of FNAC to provide rapid diagnosis and preferred to be first line diagnostic procedure.

    2007-01-01

    Objective: To discover new proteomic biomarkers of hepatocellular carcinoma. Methods: Surface enhanced laser desorption/ionization time-of-flight (SELDI-TOF) mass spectrometry was used to discover biomarkers for differentiating hepatocellular carcinoma and chronic liver disease. A population of 50 patients with hepatocellular carcinoma and 33 patients with chronic liver disease was studied. Results: Twelve proteomic biomarkers of hepatocellular carcinoma were detected in this study. Three proteomic biomarkers were highly expressed in hepatocellular carcinoma and nine proteomic biomarkers were highly expressed in chronic liver disease. The most valuable proteomic biomarker with m/z=11498 had no similar diagnostic value as α-fetoprotein. Conclusion:Some of the twelve proteomic biomarkers may become new biomarkers of hepatocellular carcinoma.

    2014-01-01

    Hashimoto's thyroiditis (HT) has been found to be associated with lymphoma, papillary carcinoma and Hürthle cell neoplasms of thyroid. In contrast, there are only a few reports of co-existence of HT with medullary carcinoma of thyroid. An overall prevalence of medullary carcinoma of only 0.35% has been reported in HT patients. Such a rare combination is being presented here. A 33 year old female presented with history of goiter for one year. Fine needle aspiration cytology (FNAC) of the swelling revealed cytological features suggestive of medullary carcinoma of thyroid. Histopathological examination of total thyroidectomy specimen revealed Hashimoto's thyroiditis along with medullary carcinoma of thyroid. Although Hashimoto's thyroiditis can uncommonly co-exist with thyroid neoplasm, its association with medullary carcinoma is extremely rare and hence being presented.

    Three tumor markers for hepatocellular carcinoma (HCC) are available in Japan: alpha-fetoprotein (AFP), protein induced by vitamin K absence or antagonists-II (PIVKA-II), and Lens culinaris agglutinin-reactive fraction of alpha-fetoprotein (AFP-L3). Although AFP has drawbacks in its specificity, it is widely utilized in treatment evaluation and prognosis prediction. PIVKA-II is a unique marker that does not correlate with AFP value and can predict microvascular invasion. AFP-L3 is a highly specific marker and strong predictor of poor prognosis. These three markers are indispensable in every aspect of clinical practice of hepatocellular carcinoma including surveillance, diagnosis, treatment evaluation, and prognosis prediction.

    Iris Tischoff; Andrea Tannapfel

    2008-01-01

    As for many other tumors, development of hepatocellular carcinoma (HCC) must be understood as a multistep process with accumulation of genetic and epigenetic alterations in regulatory genes, leading to activation of oncogenes and inactivation or loss of tumor suppressor genes (TSG). In the last decades, in addition to genetic alterations, epigenetic inactivation of (tumor suppressor) genes by promoter hypermethylation has been recognized as an important and alternative mechanism in tumorigenesis. In HCC, aberrant methylation of promoter sequences occurs not only in advanced tumors, it has been also observed in premalignant conditions just as chronic viral hepatitis B or C and cirrhotic liver. This review discusses the epigenetic alterations in hepatocellular carcinoma focusing DNA methylation.

    Case: A 63-year-old male presented with unintentional weight loss of 20 pounds over a 4-month duration. He reported loss of appetite, intermittent post-prandial nausea, bloating and early satiety. He also complained of dyspepsia and had been treated for reflux during the previous 2 years. He denied vomiting, dysphagia, odynophagia, abdominal pain, melena, hematochezia, or alterations in bowel habits. Additionally, he denied fevers, night sweats, cough, or dyspnea. He quit smoking 25 years ago, and denied alcohol use. His past medical history was significant for basal cell carcinoma treated with local curative therapy and he was without recurrence on surveillance. Pertinent family history included a paternal uncle with lung cancer at the age of 74. Physical examination was unremarkable except for occult heme-positive stools. Laboratory evaluation revealed elevated liver enzymes (ALT-112, AST-81, AlkPhos-364). CT scan of the chest, abdomen and pelvis showed diffuse heterogeneous liver with extensive nodularity, raising the concern for metastases. Serum tumor-markers: PSA, CEA, CA 19-9, and AFP were all within normal limits. Screening colonoscopy was normal, but esophagogastroduodenoscopy revealed a malignant-appearing ulcerative lesion involving the gastro-esophageal junction and gastric cardia. Pathology confirmed an invasive gastric large cell neuroendocrine carcinoma. Ultrasound-guided fine needle aspiration of a hepatic lesion revealed malignant cells with cytologic features consistent with large-cell type carcinoma and positive immunostaining for synaptophysin favoring neuroendocrine differentiation. A PET-CT demonstrated intense diffuse FDG uptake of the liver, suggesting diffuse hepatic parenchymal infiltration by tumor. There were multiple foci of intense osseous FDG uptake with corresponding osteolytic lesions seen on CT scan. The remaining intra-abdominal and intra-thoracic structures were unremarkable. The patient will receive palliative systemic therapy

    2004-01-01

    Anaplastic (giant cell) thyroid carcinoma (ATC), is one of the most aggressive malignancies in humans with a median survival time after diagnosis of 3-6 months. Death from ATC was earlier seen because of local growth and suffocation. ATC is uncommon, accounting for less than 5 % of all thyroid carcinomas. The diagnosis can be established by means of multiple fine needle aspiration biopsies, which are neither harmful nor troublesome for the patient. The cytological diagnosis of this high-grade malignant tumour is usually not difficult for a well trained cytologist. The intention to treat patients with ATC is cure, although only few of them survive. The majority of the patients are older than 60 years and treatment must be influenced by their high age. We have by using a combined modality regimen succeeded in achieving local control in most patients. Every effort should be made to control the primary tumour and thereby improve the quality of remaining life and it is important for patients, relatives and the personnel to know that cure is not impossible. Different treatment combinations have been used since 30 years including radiotherapy, cytostatic drugs and surgery, when feasible. In our latest combined regimen, 22 patients were treated with hyper fractionated radiotherapy 1.6Gy x 2 to a total target dose of 46 Gy given preoperatively, 20 mg doxorubicin was administered intravenously once weekly and surgery was carried out 2-3 weeks after the radiotherapy. 17 of these 22 patients were operated upon and none of these 17 patients got a local recurrence. In the future we are awaiting the development of new therapeutic approaches to this aggressive type of carcinoma. Inhibitors of angiogenesis might be useful. Combretastatin has displayed cytotoxicity against ATC cell lines and has had a positive effect on ATC in a patient. Sodium iodide symporter (NIS) genetherapy is also being currently considered for dedifferentiated thyroid carcinomas with the ultimate aim of

    Penile carcinoma frequency varies widely in different parts of the world and comprises 1–10% of all the malignancies in males. Majority of the cases of penile carcinoma are squamous cell carcinoma of penis comprising 60% to 70% of all cases. Warty carcinoma of penis is an unusual neoplasm and a variant of penile squamous cell carcinoma comprising 5%–10% of all the variants. The other histological variants include basaloid, verrucous, papillary, sarcomatous, mixed, and adenosquamous carcinoma. The various histological entities with an exophytic papillary lesions including warty carcinoma are together referred to as the “verruciform” group of neoplasms. The warty carcinoma has to be differentiated from these lesions and is typically distinguished by histological features of hyperkeratosis, arborescent papillomatosis, acanthosis, and prominent koilocytosis with nuclear pleomorphism. We present a case of 65-year-old male with growth measuring 6 × 4 cm in the penis who underwent total penectomy and was diagnosed as warty carcinoma penis. PMID:28154768

    Circumscribe breast cancer is a well demarcated mass with or without a lobulated border simulating a benign tumor like fibroadenoma on mammography or breast US and is reported as approximate 10% of the incidence among primary breast carcinoma(1.2). Pathologically medullary, colloid, papillary, intraductal and rarely invasive ductal carcinomas are included in this group which show the less intense desmoplastic reaction than the scirrhous type cancer, resulting in the most favorable prognosis of all carcinoma of the breast. Among 214 primary breast carcinoma during the past 8 years, we experienced 6 case of pathologically proven circumscribed breast cancer(2 cases of medullary carcinoma, 1 of colloid carcinoma, 1 of intracystic papillary carcinoma, 2 of comedo type intraductal carcinoma). Clinically 2 cases showed bloody nipple discharge from one hole of a unilateral nipple orifice. Mammography showed a well circumscribed nodule with or without partial lobular contour and no pathologic calcification. Breast sonographic findings were a well defined heterogeneous hypoechoic nodule with weak posterior acoustic enhancement. Characteristically a thin dilated lactiferous duct between the mass and the nipple on US could be detected in 2 cases which clinically was accompanied by bloody nipple discharge. Although the mammographic criteria is promising as benign tumor, the possibility of circumscribed as benign tumor, the possibility of circumscribed breast carcinoma must be considered in heterogeneous hypoechoic nodule with weak posterior acoustic enhancement in US, especially in the presence of a dilated lactiferous duct between the mass and the nipple with bloody nipple discharge.

    Full Text Available Background. Microcystic variant of urothelial carcinoma is one of the new variants of urothelial carcinoma that was added to the WHO classification in 2004. Aims. To review the literature on microcystic variant of urothelial carcinoma. Methods. Various internet search engines were used to identify reported cases of the tumour. Results. Microscopic features of the tumour include: (i Conspicuous intracellular and intercellular lumina/microcysts encompassed by malignant urothelial or squamous cells. (ii The lumina are usually empty; may contain granular eosinophilic debris, mucin, or necrotic cells. (iii The cysts may be variable in size; round, or oval, up to 2 mm; lined by urothelium which are either flattened cells or low columnar cells however, they do not contain colonic epithelium or goblet cells; are infiltrative; invade the muscularis propria; mimic cystitis cystica and cystitis glandularis; occasionally exhibit neuroendocrine differentiation. (iv Elongated and irregular branching spaces are usually seen. About 17 cases of the tumour have been reported with only 2 patients who have survived. The tumour tends to be of high-grade and high-stage. There is no consensus opinion on the best option of treatment of the tumour. Conclusions. It would prove difficult at the moment to be dogmatic regarding its prognosis but it is a highly aggressive tumour. New cases of the tumour should be reported in order to document its biological behaviour.

    Recent improvements on the therapeutical management of hepatocellular carcinoma are revised with special attention to evaluate the role of surgery for the disease. Considering that definitive surgical intervention is not feasible in most cases because of extreme tumor extension, multiplicity of tumor foci, and associated advanced liver cirrhosis at the time of diagnosis, others forms of treatment are listed, such as transcatheterarterial chemoembolization, percutaneous ethanol and acetic acid injections, and chemotherapy only to a small portion of patients with no indication for standard treatments. The emerging role of retinoic acid metabolism blocking agents, was examined and may offer a significant new potential treatment for cancer, inclusive the possibility of combining other anticancer drugs with exogenous retinoids or modulation of endogenous retinoids as a real opportunity to advance our ability to treat or prevent human cancer effectively Octreotide, nitrosamine and other drugs are analyzed and is concluded that improves survival and is a valuable alternative in the treatment of inoperable hepatocellular carcinoma. The potential role of intersticial laser coagulation for patients with irresectable hepatic tumors was investigated, and in terms of experience, it has now been developed sufficiently to study its effect on these patients survival. The homeostatic control of angiogenesis and its influences on the tumor growth and for migration of metastatic cells, was focused in this concise review, given that hepatocytes are the source of much of the precursor pool, regulation of angiogenesis may be regarded as a new liver function with important consequences for tissue repair and cancer. Early hepatocellular carcinoma and its recognition in routine clinical practice contributes to improved patients survival. Recombinant-Interferon-alpha therapy surely prevents, the development of cirrhosis or hepatocellular carcinoma in about one-third of patients, with

The duration of symptoms varies from 6 months to 2 years. Among the various aetiological factors, smoking, alcohol intake, spicy hot food intake, industrial pollution and achalasia cardia are a few worth mentioning. AIM OF THE STUDY To evaluate the differences in the predisposing factors causing squamous cell carcinoma and adenocarcinoma of oesophagus in this part of India. MATERIALS AND METHODS The study is conducted in the Department of Surgery at Government Medical College Hospital, Kozhikode; Kerala. One hundred patients attending the Department with history of Dysphagia were included after thorough history taking, clinical and endoscopic examination and found to have malignant growths in the oesophagus which was confirmed by biopsy and histopathological examination. Various aetiological factors were elicited and analysed in both the histological varieties of malignancy of oesophagus. OBSERVATIONS AND RESULTS Significant number of patients with history of paan chewing presented with histological picture of squamous cell carcinoma as compared to patients who had adenocarcinoma. Gastroesophageal reflux disease was more commonly associated with adenocarcinoma. Out of 37 patients with adenocarcinoma, 31 patients had history of gastroesophageal reflux disease (83.8%. 6 patients had no history of gastroesophageal reflux disease (16.2% within histology.

    The purpose of this study was to evaluate and compare the sonographic findings of a conventional papillary carcinoma, follicular carcinoma and a follicular variant of a papillary carcinoma. A total of 308 nodules from 231 patients that were diagnosed with a papillary carcinoma and a follicular carcinoma by surgery after sonography were analyzed. The nodules consisted of a conventional papillary carcinoma (255, 83%), a follicular variant of a papillary carcinoma (25, 8%), and a follicualar carcinoma (28, 9%). We compared and analyzed the sonographic findings of each nodule for content, margin, echotexture, shape, calcification and halo sign. A conventional papillary carcinoma showed significant different sonographic findings than a follicular carcinoma and a follicular variant of a papillary carcinoma for an ill-defined or well-defined spiculated margin (63.1%), marked hypoechogenicity (85.9%) and microcalcification (49%). A follicular carcinoma showed a significant difference than a conventional papillary carcinoma for a well-defined smooth margin (92.9%), iso, hypo- or hyperechogenicity (89.3%), wider than tall shape (100%) and halo sign (82.1%). The follicular variant of a papillary carcinoma showed similar findings to a follicular carcinoma except for marked hypoechogenicity (44%, p = 0.006) and taller than wide shape (16%, p = 0.027). The follicular carcinoma and follicular variant of a papillary carcinoma showed similar sonographic findings, but findings of a conventional papillary carcinoma were different

    NUT midline carcinomas (NMCs) are rare tumors described predominantly in the pediatric age group. We recently reported two cases of these tumors occurring in the thymic region. In order to establish the true incidence of these tumors, we examined a large series of thymic carcinomas for morphological features of NUT tumor and further assessed the expression of NUTM1 (also known as NUT) protein by immunohistochemistry. The histological review of slides from 110 cases of thymic carcinoma was undertaken to identify carcinomas with mixed undifferentiated and squamous features that are typically associated with NUT carcinomas. The presenting symptoms, morphological spectrum of tumors and outcome data of patients with these histologies are presented. Immunohistochemistry for NUTM1 was performed on 35 cases of thymic carcinoma with available blocks (3 with these histological features and 32 without these features) to exclude the possibility of midline carcinoma. Tumors from 10 patients had features of mixed small cell undifferentiated squamous cell carcinoma (M:F, 1.5:1; age range, 22-79). These patients predominantly presented with advanced disease and had respiratory-related symptoms or chest pain; four had paraneoplastic syndromes. The squamous component in all cases was well differentiated with little or no atypia. The undifferentiated component varied in cell size and lacked characteristic features of small cell carcinoma. All but one patients developed metastases or died within 3 years of diagnosis. NUTM1 expression was seen in two of three tumors with these histological features and in none of the 32 cases without. Mixed small cell undifferentiated carcinomas share histological and immunohistochemical similarity with NMCs and have aggressive clinical course. These tumors are not uncommon and should be considered in the differential diagnosis of carcinomas in the thymic region as novel therapies might be available.

    Background Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Objectives Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Methods Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). Results The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. Conclusion The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

    Pathologists are expected to accurately diagnose increasingly smaller breast carcinomas. Correct classification (ie, lobular vs ductal or in situ vs invasive) directly affects subsequent management, especially when the focus is near a surgical margin or present in a needle core biopsy and is further challenging if the lesion is morphologically ambiguous. We assessed the diagnostic utility of a multiplex, trichromogen immunostain of 3 commonly employed antibodies (CK7, p63, and E-cadherin) developed in our laboratory to evaluate these small lesions. Of the 147 specimens containing minimal (defined as ≤3 mm in size) invasive carcinoma, 81 also contained in situ carcinoma. In each case, the Minimal Carcinoma Triple Stain was prepared with a parallel H&E-stained slide. Observations of staining characteristics in the focus of interest were recorded. The Minimal Carcinoma Triple Stain was diagnostically useful in all but 1 case. In a case of invasive lobular carcinoma in an excisional biopsy, the Minimal Carcinoma Triple Stain stained only the surrounding breast tissue (appropriately) and not the focus of interest. Also, a subset of 29 of 81 excisional biopsies had minimal invasive carcinoma located 2 mm or less from the inked surgical margin, in which in all cases the Minimal Carcinoma Triple Stain was fully interpretable despite morphologic distortion due to concomitant cautery artifact and tissue disruption in some cases. The Minimal Carcinoma Triple Stain offers an accurate and tissue-conserving method to diagnose small, morphologically problematic foci of breast carcinoma while ideally leaving more tissue for additional adjunctive studies.

    Intraductal carcinoma is a precancerous lesion of the breast and the immediate precursor of invasive ductal carcinoma. Multiphoton microscopy (MPM) was used to monitor the progression from intraductal carcinoma to invasive ductal carcinoma, which can improve early detection of precursor lesions and halt progression to invasive neoplastic disease. It was found that MPM has the capability to reveal the qualitative changes in features of cells, structure of basement membranes, and architecture of collagens during the development from intraductal carcinoma to invasive ductal carcinoma, as well as the quantitative alterations in nuclear area, circle length of basement membrane, and collagen density. Combined with intra-fiberoptic ductoscopy or transdermal biopsy needle, MPM has the potential to provide immediate histological diagnosis of tumor progression in the field of breast carcinoma.

    2010-12-01

    Raf-1 kinase inhibitory protein (RKIP) has been implicated in several fundamental signal transduction pathways that control cellular growth, differentiation, apoptosis and migration. RKIP is reduced in a variety of human carcinomas, but RKIP expression in thyroid carcinomas has not been analyzed at the protein level. In this study, we examined the immunohistochemical expression of RKIP in various subtypes of thyroid carcinoma. Immunostaining for RKIP was performed on 104 cases of primary thyroid carcinoma (40 papillary, 29 follicular, 11 medullary, 11 poorly differentiated, and 13 anaplastic carcinomas) and 26 cases of nodal metastatic tumor (17 papillary, 4 medullary, and 5 anaplastic carcinomas). Normal thyroid tissue and all cases of follicular, papillary, and medullary carcinomas showed uniform, strong cytoplasmic immunoreactivity for RKIP. With the exception of one case, poorly differentiated carcinomas also revealed strong RKIP expression. In contrast, RKIP expression was completely absent in all anaplastic carcinomas. The transition zone from the differentiated carcinoma component (strong RKIP expression) to the anaplastic carcinoma component (no RKIP expression) demonstrated a completely opposite pattern of RKIP immunoreactivity. This reduction of RKIP expression in anaplastic carcinoma was statistically significant (P carcinomas showed uniform, strong cytoplasmic RKIP immunoreactivity, in contrast, in metastatic anaplastic carcinomas, RKIP expression was completely absent. RKIP expression is significantly reduced in anaplastic thyroid carcinoma as compared to other subtypes of thyroid carcinoma. Further studies are necessary to elucidate the precise mechanism of RKIP action in anaplastic thyroid carcinoma.

    The aim of the study was to determine the incidence of coexistence of papillary carcinoma and Hashimoto's thyroiditis in cytologic material. Cytologic findings were collected from 10508 patients that underwent ultrasound-guided fine needle aspiration cytology (FNAC) of the thyroid. Hashimoto's thyroiditis was found in 2156 (20.5%) and papillary carcinoma in 269 (2.6%) of 10508 patients with FNAC, whereas both Hashimoto's thyroiditis and papillary carcinoma were present in 42 (0.4%) patients. Among patients with FNAC diagnosis of Hashimoto's thyroiditis, the prevalence of papillary carcinoma was 1.9%. Among patients with FNAC diagnosis of papillary carcinoma, the prevalence of Hashimoto's thyroiditis was 15.6%. There was no statistically significant association between the presence of papillary carcinoma and Hashimoto's thyroiditis in patients undergoing FNAC (p=0.0522). In conclusion, in a large series of patients, the incidence of Hashimoto's thyroiditis and papillary carcinoma coexistence in cytologic material was 0.4%. There was no statistically significant relationship between Hashimoto's thyroiditis and papillary carcinoma in cytologic material.

    2014-04-01

    Full Text Available Mucinous carcinoma is also known as mucoid carcinoma, colloid carcinoma, gelatinous carcinoma and mucin producing carcinoma. They are uncommon neoplasms of the breast and the reported incidence varies from 1-4%. Most of the mucinous carcinomas occur in older age group. FNAC can aid in diagnosis of mucinous carcinoma with only a few FNAC studies documented in literature. We present here a 56year old lady with a huge ulcerated breast mass clinically diagnosed as Malignant Phyllodes tumor. An FNAC was done which showed epithelial cell clusters with mild atypia in a background of both bluish violet and pink extracellular material. Spindle shaped cells were noted in the ground substance which led to a diagnosis of a phyllodes tumor with extensive myxoid change. Mastectomy was performed and the histopathological features confirmed a diagnosis of mucinous carcinoma. The tumor had areas showing thick collagenized fibrous septae separating tumor cell clusters and also areas of fibrosis. The pitfall in FNAC diagnosis may be due to the sampling from such an area.

    Four cases of vaginal metastases of renal carcinoma are reported. This is an incidence of 1.3% in 313 operated patients (from 1/1/70 to 12/31/76). A surgical treatment of primary renal carcinoma and vaginal metastasis seems to be reasonable in there cases. Since in accordance with the literature metastatic involvement of vagina and vulva seems not to be a very rare finding, the diagnostic in renal carcinoma should imply a gynecologic examination. Although in carcinoma of the left kidney metastatic spreading into the external female genitalia most probably occurs by a retrograde venous pathway (left ovarian vein), the way of dissemination in carcinoma of the right side is unclear.

    Peritoneal carcinoma is a rare primary tumor, described in the literature almost exclusively in women. This report describes our clinicopathological findings in a 51-year-old male patient with peritoneal carcinoma and ascites. Pathologic studies included routine histology, immunohistochemistry and electron microscopy on biopsy and autopsy tumor tissue. After chemotherapy, the patient achieved a complete remission twice, lasting for 14 months and 8 months, respectively, and died after 3 years. His clinical course was similar to that of female patients with peritoneal carcinoma or advanced ovarian cancer. Our case confirms the existence of primary peritoneal carcinoma in males. In addition, it shows that this entity responds to the same chemotherapy as used for ovarian cancer and primary peritoneal carcinoma in females.

    Patients undergoing thyroidectomies at Evanston (I11) Hospital, during a six-month period had immunological studies performed preoperatively. No differential could be found between those with carcinoma or benign pathologic findings. T- and B-cell distribution and lymphocytic response to mitogens varied widely. Quantitative immunoglobulins showed slightly increased levels of IgG in patients wih carcinoma and thyroiditis in comparison with those patients with adenomas. Antithyroglobulin antibodies were negative in all patients. Pathology slides from 107 patients with thyroid carcinoma between 1972 and 1978 at Evanston Hospital were reviewed for the presence of thyroiditis, either focal or diffuse. It was found that 50% of all carcinomas had either diffuse or focal thyroiditis. Diffuse thyroiditis was more common in patients with no history of irradiation and papillary carcinoma, and in younger age groups.

    Full Text Available Nasopharyngeal carcinoma has long been reported as the predominant type of cancer associated with dermatomyositis in many several Asian countries, including Hong Kong, Singapore, and Southern-Cina. Dermatomyositis is one of the idiopathic inflammatory myopathies showing characteristic cutaneous manifestations. Reviews from the western literature have demonstrated that certain cancers, such as ovarian and breast carcinoma in women and lung and prostate carcinoma in men, are highly associated with DM relative to the general population. We report the case of a Caucasian Italian patient with nasopharyngeal carcinoma and dermatomyositis. Considering the rarity of nasopharyngeal carcinoma among whites, both the detection and the report of each new case are noteworthy in defining the geographic and ethnic distribution of this tumor.

    Objective: To study the clinical pathological characteristics of ovarian metastasis of endometrial carcinoma and the factors affecting prognosis. Methods: Retrospective analysis was made to the clinical pathological outcome of endometrial carcinoma patients receiving surgical treatment in our hospital from January 1990 to December 2002. Results:Among the 191 cases of endometrial carcinoma patients, 17 cases (8.9%) had ovarian metastasis and young patients were more likely to have ovarian metastasis. The multiple factor analysis showed that the independent risk factors of ovarian metastasis in endometrial carcinoma included the depth of myometrial invasion, lymph node metastasis and pathological types. Conclusion: Ovarian metastasis in patients with endometrial carcinoma is associated with poor prognosis, the depth of myometrial invasion, lymph node metastasis and histologic types are independent risk factors affecting the prognosis. For young patients at early stage of the disease, it should be prudent as to whether to retain the ovary.

    Full Text Available High-grade papillary urothelial carcinoma regularly invades the bladder wall, adjacent prostate, seminal vesicles, ureters, vagina, rectum, retroperitoneum, and regional lymph nodes. In advanced stages, it may disseminate to the liver, lungs, and bone marrow. On rare occasions, unusual metastatic foci like skin have been reported. The incidence of urothelial carcinoma has increased with associated rise in variants of urothelial carcinoma and unusual metastatic foci. It is imperative that urologists and pathologists are aware of the unusual variants and unusual metastatic locations to expedite the diagnostic process. Hereby we report an unusual case of secondary involvement of spinal nerve by conventional urothelial carcinoma. Also a second case of rhabdoid variant of urothelial carcinoma showing synchronous involvement of bladder and subcutaneous tissue of upper extremity is presented.

    Cancer of stomach, colon and liver are a group of the most common cancer in Korea. However, results with current therapeutic modalities are still unsatisfactory. The intensive efforts have been made to understand basic pathogenesis and to find better therapeutic tools for the treatment of this miserable disease. We studied the alteration of tumor suppressor genes and oncogenes in hepatocellular carcinoma in Korea. We found that alteration of Rb gene, APC were 33 %, 13 % respectively. But alterations of oncogenes such as myc, ras and mdm2 were rarely found. Our results suggests that HBV may act as oncogenic role in hepatocarcinogenesis instead of oncogenes. 6 figs, 2 tabs.

    The authors reviewed 227 new bladder cancers from two main hospitals in Beirut Lebanon. They analyzed the morphologic features of these tumours, insisting particularly on the number, the size, the site, the grade, the stage, the mode of spread and the vascular permeation. The latter four factors appear to be directly related to the metastatic spread of these tumours. The metastatic patterns are summarized, regional lymph node metastases being the main problem because of therapeutic implications (radical surgery, radiotherapy and chemotherapy). The problems of generalized carcinoma, unusual lymph node metastases and solitary distant metastases are also considered.

    About 80% of hepatocellular carcinoma (HCC) is caused by hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infections especially in the setting of established cirrhosis or advanced fibrosis, making HCC prevention a major goal of antiviral therapy. HCC tumors are highly complex and heterogeneous resulting from the aberrant function of multiple molecular pathways. The roles of HCV or HBV in promoting HCC development are still either directly or indirectly are still speculative, but the evidence for both effects is compelling. In patients with chronic hepatitis viral infection, cirrhosis is not a prerequisite for tumorigenesis.

    GATA-3, a member of the GATA family of zinc-finger DNA binding proteins, and FOXA1, a member of the forkhead transcription factor family, are both associated with estrogen receptor expression. Both GATA-3 and FOXA1 are useful markers for breast carcinoma, but their expression in the different breast cancer subtypes and other neoplasms has not been thoroughly evaluated. We examined the expression of GATA-3 and FOXA1 in estrogen receptor-positive, Her2/neu-positive, and triple-negative breast carcinomas as well as in 10 other common carcinomas, including hepatocellular, colonic, pancreatic, gastric, endometrial (endometrioid), lung, prostatic, renal cell, urothelial, and ovarian serous carcinomas. Primary and metastatic melanomas and mesotheliomas were also evaluated. GATA-3 and FOXA1 staining of estrogen receptor-positive breast carcinomas was seen in 96.6% and 96.2%, respectively. In triple-negative breast carcinomas, GATA-3 and FOXA1 staining was seen in 21.6% and 15.9%, respectively. Among the other tumors, GATA-3 staining was only seen in urothelial carcinoma (70.9%) and FOXA1 staining was only seen in prostatic (87.5%), urothelial (5.1%) carcinomas, and mesotheliomas (40.0%). In conclusion, GATA-3 and FOXA1 are excellent breast carcinoma markers; however, their utility is limited in the triple-negative subtype. The utility of FOXA1 in diagnosing prostatic carcinoma and mesothelioma warrants further investigation.

    Full Text Available Hepatocellular carcinoma (HCC is an epithelial tumor derived from hepatocytes; it accounts for 80% of all primary liver cancers and ranks globally as the fourth leading cause of cancer-related deaths. HCC treatment is a multidisciplinary and a multimodal task, with surgery in the form of liver resection and liver transplantation (LT representing the only potentially curative modality. However, there are variable opinions and discussions about applying these surgical options and using other supporting treatments. This article is a narrative review that includes articles published from 1984 to 2013 located by searching scientific databases such as PubMed, SCOPUS, and Elsevier, with the main keyword of hepatocellular carcinoma in addition to other keywords such as liver transplantation, liver resection, transarterial chemoembolization, portal vein embolization, bridging therapy, and downstaging. In this review, we focus mainly on the surgical treatment options offered for HCC, in order to illustrate the current relevant data available in the literature to help in applying these surgical options and to use other supporting treatment modalities when appropriate.

    Full Text Available Human papillomavirus (HPV infection is the most common sexually transmitted disease worldwide and can result in pre-malignancies or overt malignancies of the skin and mucosal surfaces. HPV-related illnesses are an important personal and public health problem causing physical, mental, sexual and financial detriments. Moreover, this set of malignancies severely affects the immunosuppressed population, particularly HIV-positive patients and organ-transplant recipients. There is growing incidence of HPV-associated anogenital malignancies as well as a decrease in the average age of affected patients, likely related to the rising number of high-risk individuals. Squamous cell carcinoma is the most common type of HPV-related malignancy. Current treatment options for HPV infection and subsequent disease manifestations include imiquimod, retinoids, intralesional bleomycin, and cidofovir; however, primary prevention with HPV vaccination remains the most effective strategy. This review will discuss anogenital lesions in immunocompromised patients, cutaneous warts at nongenital sites, the association of HPV with skin cancer in immunocompromised patients, warts and carcinomas in organ-transplant patients, HIV-positive patients with HPV infections, and the management of cutaneous disease in the immunocompromised patient.

  8. Estrogen receptors in breast carcinoma.

    Huaman, A

    1979-11-01

    On the basis of estrogen receptor assays, breast carcinomas are presently classified as estrogen-dependent tumors, which respond to endocrine therapy, and autonomous tumors, for which endocrine therapy is useless. This paper presents a short review of the biochemical principles of estrogen dependence, the procedures used to determine estrogen receptors, and the clinical applications of the findings of these assay procedures. Biobhemically, the estroogen dependence of normal breast cells is explained as a biochemical reaction occurring between the circulating estradiol and the breast cell, which occurs in 3 steps: 1) circulating estradiol penetrates the cellular membrane by passive diffusion, followed by 2) combining of estradiol with the estrogen-binding protein (estrophilin) and formation of an estrogen receptor complex which undergoes activation and translocation into the nucleus, to result in 3) the activated steroid receptor which combines with the nuclear charomatin and stimulates ribonucleic acid synthesis for the formation of estradiol binding proteins or estradiol receptors. The cytosol method of Wittliff et al. is described in brief and entails radioactive competitive analysis; the other available laboratory procedure is immunofluorescence of tumor sections. Quantification of estrogen receptor content can be used clinically to decide on ablative endocrine therapy, to determine the effectiveness of anti-estrogen administration, to determine the primary site of metastatic carcinoma, and as a screenng device.

Patient was admitted with the symptoms of lower urinary tract. Transurethral resection of prostate (TUR-P) was carried out. Revealing Gleason 5 + 3 = 8 prostate adenocarcinoma in TUR-P material. Thereby, a Radical Prostatectomy procedure was planned. In operation, frozen examination revealed adenocarcinoma metastasis to the obturator lymph node. The operation was terminated. In the postoperative 3rd month, the patient was re-admitted with acute urinary system symptoms. A cystoscopy performed and complete resection of the mass was performed. The pathological examination reported that the tumor was compatible with undifferentiated adenocarcinoma owing to presence of poorly differentiated tumoral cells and detection of adenocarcinoma in a relatively small (<1%) focus. 4 month after the operation, the patient underwent another cyctoscopic examination which revealed the prostatic lounge and most of the bladder lumen to be filled with tumoral tissue. The tumoral tissues was resected incompletely. This material was diagnosed to be "Sarcomatoid Malignant Tumor" upon the new evidences of progressive dedifferentiation and predominant sarcomatoid appearance, compared with the former TUR-P materials. Subsequent PET-CT scan depicted multiple metastasis. The patient was referred to oncology department. In conclusion, sarcomatoid carcinoma is a malignant variant that brings along diagnostic and treatment difficulties.

    We used DNA microarrays to characterize the global gene expression patterns in surface epithelial cancers of the ovary. We identified groups of genes that distinguished the clear cell subtype from other ovarian carcinomas, grade I and II from grade III serous papillary carcinomas, and ovarian from breast carcinomas. Six clear cell carcinomas were distinguished from 36 other ovarian carcinomas (predominantly serous papillary) based on their gene expression patterns. The differences may yield insights into the worse prognosis and therapeutic resistance associated with clear cell carcinomas. A comparison of the gene expression patterns in the ovarian cancers to published data of gene expression in breast cancers revealed a large number of differentially expressed genes. We identified a group of 62 genes that correctly classified all 125 breast and ovarian cancer specimens. Among the best discriminators more highly expressed in the ovarian carcinomas were PAX8 (paired box gene 8), mesothelin, and ephrin-B1 (EFNB1). Although estrogen receptor was expressed in both the ovarian and breast cancers, genes that are coregulated with the estrogen receptor in breast cancers, including GATA-3, LIV-1, and X-box binding protein 1, did not show a similar pattern of coexpression in the ovarian cancers.

    Objective: To study the mechanism, clinical characteristics, therapy regimens, and survival of cervical carcinoma metastases to the brain. Methods: We retrospectively analyzed 11 patients with brain metastases from cervical carcinoma. Results: Two cases were at stage lb, two at IIa, and seven at IIIb, respectively. Histologically, they were squamous cell carcinoma (6 cases), adeno-squamous carcinoma (2 cases), small cell carcinoma (2 cases), or adenocarcinoma (1 cases), poorly differentiated. Eight were accompanied with lung, liver, and bone metastases disease and three had no any other systemic metastases at the time of the brain metastases diagnosis. Two had controlled, and other nine were uncontrolled or progressive primary disease. The median interval from the diagnosis of the primary carcinoma to the detection of brain lesion was 14.6 months. Headache was the most common symptom of brain metastases. Eight of 11 patients developed multiple lesions and other 3 cases had a solitary lesion in brain. The patients were treated by combination of surgery and whole brain radiation therapy (WBRT) (3 cases), stereotactic radiosurgery (SRS) (3 cases), or WBRT (5 cases). The patients had a median survival of 6.6 months. Conclusion: Brain metastases are not always a late complication of cervical carcinoma. The development of the metastases is related to pathological type, poorly differentiation, and advanced stage. Surgery and SRS arc the appropriate therapy regimen for these patients.

    Full Text Available Pleomorphic carcinoma is a rare lesion and the literature contains few reports of pleomorphic carcinoma of the gallbladder. The present study reports a rare case of primary pleomorphic carcinoma of the gallbladder for which we were able to perform curative surgery. A 77-year-old woman with dementia developed nausea and anorexia, and computed tomography demonstrated irregular thickening of the gallbladder wall. Drip infusion cholangiography and endoscopic retrograde cholangiopancreatography revealed no stenosis of the common and intrahepatic bile ducts. We suspected carcinoma of the gallbladder without lymph node metastasis and invasion to the common bile duct. We guessed it to be resectable and performed open laparotomy. At operation, the fundus of the gallbladder was adherent to the transverse colon, but no lymph node and distant metastases were detected. Therefore, we performed curative cholecystectomy with partial colectomy. Histopathology and immunostaining showed coexistence of an adenocarcinoma, squamous cell carcinoma and sarcomatous tumor of spindle-shaped cell, as well as transition zones between these tumors. We diagnosed stage I pleomorphic carcinoma of the gallbladder. No recurrence has been observed for one and a half years. The biological behavior of pleomorphic carcinoma of the gallbladder remains unknown. It will be necessary to accumulate more case reports of this tumor in order to define diagnostic criteria.

    AIM: To demonstrate the necessity of intraoperative endoscopy in the diagnosis of secondary primary tumors of the upper digestive tract in patients with obstructive hypopharyngeal carcinoma.METHODS: Thirty-one patients with hypopharyngeal squamous cell carcinoma had been operated, with radical intent, at our Institution in the period between 1978 and 2004. Due to obstructive tumor mass, in 7(22.6%) patients, preoperative endoscopic evaluation of the esophagus and stomach could not be performed. In those patients, intraoperative endoscopy, made through an incision in the cervical esophagus, was standard diagnostic method for examination of the esophagus and stomach.RESULTS: We found synchronous foregut carcinomas in 3 patients (9.7%). In two patients, synchronous carcinomas had been detected during preoperative endoscopic evaluation, and in one (with obstructive carcinoma) using intraoperative endoscopy. In this case, preoperative barium swallow and CT scan did not reveal the existence of second primary tumor within esophagus, despite the fact that small, but T2 carcinoma, was present.CONCLUSION: It is reasonable to use intraoperative endoscopy as a selective screening test in patients with obstructive hypopharyngeal carcinoma.

    Syringoid carcinoma (syringoid eccrine carcinoma, or eccrine epithelioma) is a rare cutaneous tumor with some controversy regarding its correct definition. This tumor shows a slow growth and has often been for many years, some decades before diagnosis. It may also be difficult to differentiate from its benign counterpart (syringoma) or other adnexal carcinoma and cutaneous metastasis. There have been limited case reports of syringoid carcinoma in foreign literatures but none from Iran. Here we report a case of syringoid carcinoma in a 52 year-old Iranian man. Syringoid eccrine carcinoma is a very rare and uncommon diagnosed tumor thought to be derived from eccrine sweat apparatus. It locally invasive, destructive and often shows recurrence. It may also be difficult to differentiate from metastatic adenocarcinoma.

    Distinguishing ampullary carcinoma from pancreatic carcinoma is important because of their different prognoses. microRNAs are differentially expressed according to the tissue of origin. However, there is rare research on the differential diagnosis between the two types of cancers by microRNA in periampullary cancers. The present study was undertaken to compare microRNA profiles between ampullary and pancreatic carcinomas using microarrays. miR-215 was most significantly overexpressed in ampullary carcinomas; whereas the expressions of miR-134 and miR-214 were significantly lower in ampullary carcinomas than in pancreatic carcinomas. When these discriminatory microRNAs were applied to liver metastases, they were correctly predicted for the tissue of origin. Although this study is limited by small sample size, striking difference in microRNA expression and concordant expression of discriminating microRNAs in primary tumors and metastases suggest that these novel discriminatory microRNAs warrant future validation.

    Full Text Available OBJECTIVE: The majority of cases of hepatocellular carcinoma have been reported in individuals with cirrhosis due to chronic viral hepatitis and alcoholism, but recently, the prevalence has become increasingly related to nonalcoholic steatohepatitis around the world. The study aimed to evaluate the clinical and histophatological characteristics of hepatocellular carcinoma in Brazilians' patients with nonalcoholic steatohepatitis at the present time. METHODS: Members of the Brazilian Society of Hepatology were invited to complete a survey regarding patients with hepatocellular carcinoma related to nonalcoholic steatohepatitis. Patients with a history of alcohol intake (>20 g/day and other liver diseases were excluded. Hepatocellular carcinoma diagnosis was performed by liver biopsy or imaging methods according to the American Association for the Study of Liver Diseases’ 2011 guidelines. RESULTS: The survey included 110 patients with a diagnosis of hepatocellular carcinoma and nonalcoholic fatty liver disease from nine hepatology units in six Brazilian states (Bahia, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Rio Grande do Sul. The mean age was 67±11 years old, and 65.5% were male. Obesity was observed in 52.7% of the cases; diabetes, in 73.6%; dyslipidemia, in 41.0%; arterial hypertension, in 60%; and metabolic syndrome, in 57.2%. Steatohepatitis without fibrosis was observed in 3.8% of cases; steatohepatitis with fibrosis (grades 1-3, in 27%; and cirrhosis, in 61.5%. Histological diagnosis of hepatocellular carcinoma was performed in 47.2% of the patients, with hepatocellular carcinoma without cirrhosis accounting for 7.7%. In total, 58 patients with cirrhosis had their diagnosis by ultrasound confirmed by computed tomography or magnetic resonance imaging. Of these, 55% had 1 nodule; 17%, 2 nodules; and 28%, ≥3 nodules. CONCLUSIONS: Nonalcoholic steatohepatitis is a relevant risk factor associated with hepatocellular carcinoma in

    Prompted by the finding that the radiological incidence of small bowel ascariasis in the patient with gastric carcinoma was unexpectedly lower than the incidence in the normal population, a clinical study was performed to investigate possible relationship between gastric carcinoma and intestinal ascariasis. As a preliminary survey, we reviewed the radiological incidence of ascariasis in a total of 2,446 cases of upper GI series performed at the Department of Radiology, St Mary's Hospital Catholic Medical College. These included 1,573 normal subjects, 146 gastric carcinoma patients, 100 benign gastric ulcer and 249 duodenal ulcer patients and 378 other upper GI diseases. Following the preliminary study, a more accurate parasitologic study was conducted in another 578 normal subjects and 51 gastric carcinoma patients. The radiological incidences of ascaiasis in normal subjects and gastric carcinoma patients were 15.1% and 28.1%, respectively. The incidence of overall helminthiasis including ascaris lumbricoides, trichocephalus trichiurus and trichostrongyloides orientalis in normal subjects of the present series was 73.5%. This figure is virtually the same with 69.1% of the general population incidence reported by Kim, et al. (1971), but the incidence in gastric carcinoma patients was 94.1%. The high incidence pattern of overall helminthiasis in gastric carcinoma patients is, however, reversed as for as ascariasis is concerned. Thus, the incidence of ascariasis of gastric carcinoma patients was much lower than that of normal subjects (9.8% vs 19.4%). From the present observation, it is postulated that there can be some possible antagonistic relationship between evolution of gastric carcinoma and small bowel infestation of ascaris lumbricoides.

  19. Prevalence of Glomerulopathies in Canine Mammary Carcinoma

    The incidence and prevalence of paraneoplastic glomerulopathy, especially associated with carcinoma, are a matter of debate and the causal link between cancer and glomerular diseases remains unclear. The aim of this study was to evaluate renal biopsies of selected bitches with spontaneous mammary gland carcinoma. We hypothesized that dogs with mammary carcinomas would show histologic evidence of glomerular pathology. A prospective study was performed in dogs with naturally occurring mammary carcinoma that were undergoing tumor resection and ovariohysterectomy. We evaluated renal biopsies of 32 bitches with spontaneous mammary gland carcinoma and 11 control dogs without mammary gland neoplasia. Samples were obtained from the left kidney and the biopsy material was divided for light microscopy (LM), immunofluorescence (IF) and transmission electron microscopy (TEM). Light microscopy abnormalities were identified in 78.1% of dogs with mammary carcinoma (n = 25) and in none of the dogs in the control group. Focal glomerular mesangial matrix expansion was the most common alteration (n = 15, 60.0%), but mesangial cell proliferation (n = 9, 36.0%) and focal segmental glomerulosclerosis (n = 9, 36.0%), synechiae (n = 7, 28.0%), and globally sclerotic glomeruli (n = 6, 24.0%) were also frequent in dogs with malignancy. Immunofluorescence microscopy revealed strong IgM staining was demonstrated in 64.3% (n = 18) of carcinoma dogs. Transmission electron microscopy from dogs with carcinoma revealed slight changes, the most frequent of which was faint sub-endothelial and mesangial deposits of electron-dense material (78%). Mesangial cell interpositioning and segmental effacement of podocyte foot processes were identified in some specimens (45%). Changes in the glomerulus and proteinuria are common in dogs with naturally occurring mammary carcinoma and this condition appears to provide an excellent large animal model for cancer-associated glomerulopathy in humans.

    A very uncommon tumor, primary intraosseous carcinoma (PIOC), is a carcinoma arising within the jaw. The definite diagnosis of PIOC is often difficult as the lesion must be distinguished from alveolar carcinoma that may invade the bone from the overlying soft tissues or from the tumors that have metastasized to the jaw from a distant site. A case of PIOC arising in the mandible is presented. The clinical, radiologic, and histologic features are described. This rare lesion should be considered in any differential diagnosis of a jaw radiolucency.

    Full Text Available Basal cell carcinoma (BCC is the most common malignant tumor of skin. The most common site (80% is head and neck. BCC exhibits a varied morphology such as adenoid, keratotic, sebaceous, basosquamous, apocrine, eccrine or fibroepithelial. Tumors with a similar histopathological picture are cutaneous adenoid cystic carcinoma and primary cutaneous cribriform apocrine carcinoma. Immunohistochemistry, along with clinical findings, acts as an adjunct in reaching an accurate diagnosis. Here, we present an interesting case of adenoid BCC in a 55-year-old man.

    Full Text Available Hematogenous spread from carcinoma of tonsil is an uncommon event and skin is an extremely rare site of metastasis. We encountered a 40-year-old male patient who initially presented with carcinoma of the tonsil with T3N2cMO disease and treated by curative radiotherapy. After about 2 years, he developed a skin lesion in the periorbital region which on cytological examination turned out to be metastasis from tonsillar carcinoma. The present paper describes this rare case report along with a brief review of the literature.

    Full Text Available An uncircumcised 65 year male, with history of phimosis presented with retention of urine and ulceration and bleeding in the prepuce. Circumcision was done under local anesthesia which revealed an ulcero-proliferative growth involving the prepuce and glans. The prepucial skin was sent for histopathological examination. The diagnosis was histopathologically confirmed as Acantholytic Squamous Cell Carcinoma. Acantholytic squamous cell carcinoma is a highly malignant, unusual variant of squamous cell carcinoma invading deeper anatomic structures and is associated with a higher incidence of regional metastasis and mortality.

    2010-12-01

    Full Text Available Pancreatic carcinoma is the fourth-leading cause of cancer death and is characterized by early invasion and metastasis. The developmental program of epithelial-mesenchymal transition (EMT is of potential importance for this rapid tumor progression. During EMT, tumor cells lose their epithelial characteristics and gain properties of mesenchymal cells, such as enhanced motility and invasive features. This review will discuss recent findings pertinent to EMT in pancreatic carcinoma. Evidence for and molecular characteristics of EMT in pancreatic carcinoma will be outlined, as well as the connection of EMT to related topics, e.g., cancer stem cells and drug resistance.

    2016-01-01

    Full Text Available Buccal carcinoma is one of the most common oral malignant neoplasms, especially in the South Asian region. Radiotherapy, which plays a significant role in the treatment of this carcinoma, has severe adverse effects. Different types of prosthesis may be constructed to protect healthy tissues from the adverse effects of treatment and concentrate radiation in the region of the tumor mass. However, the technique for fabrication of shielding stent with Lipowitz's alloy (cerrobend/Wood's alloy has not been well documented. This article describes detailed technique for fabrication of such a stent for unilateral buccal carcinoma patients to spare the unaffected oral cavity from potential harmful effects associated with radiotherapy.

    2011-01-01

    Full Text Available Medullary thyroid carcinoma accounts for 4% of thyroid carcinoma and originates from parafollicular cells, secreting calcitonin and carcinoembryonic antigen (CEA. Conventional radiographic modalities such as Computerized Tomography (CT, Magnetic Resonance Imaging (MRI, and Ultrasonography (U/S, are used for detecting recurrences following total thyroidectomy. However, metastatic disease frequently escapes detection by the above modalities, even when its presence is suggested by persistently elevated serum calcitonin levels. In this paper, we report a case of medullary thyroid carcinoma in a 40 year-old woman who had whole body octreotide scintigraphy to evaluate and detect the origin of calcitonin and CEA secretion.

    Malignant adnexal carcinomas of the skin are rare but associated with high propensity for local recurrence, and for some of the distinct subgroups they are known to metastasize regionally or distant. Biopsy is necessary for correct diagnosis, as the lesions cannot be separated from other tumour...... types entirely on their clinical appearance. The histologic diagnosis is troublesome, and the lesions are often mistaken for their benign counterpart, basal cell carcinoma or squamous cell carcinoma. The lesions are treated with surgery. Radiotherapy and chemotherapy may play a role in treatment...

    Cholecystocolic fistula secondary to gallbladder carcinoma is extremely rare and has been reported in very few studies. Most cholecystocolic fistulae are late complications of gallstone disease, but can also develop following carcinoma of the gallbladder when the necrotic tumor penetrates into the adjacent colon. Although no currently available imaging technique has shown great accuracy in recognizing cholecystocolic fistula, abdominopelvic computed tomography may show fistulous communication and anatomical details. Herein we report an unusual case of cholecystocolic fistula caused by gallbladder carcinoma, which was preoperatively misdiagnosed as hepatic flexure colon carcinoma.

    The presence of pleomorphic tumor giant cells in thyroid carcinomas of follicular cell origin is always worrisome for the pathologist as they first of all refer to anaplastic carcinoma, one of the most aggressive human malignancies. However, non-anaplastic pleomorphic giant cells are well described in other thyroid diseases, most often benign. In this paper, we describe four cases of papillary thyroid carcinoma displaying pleomorphic tumor giant cells with features that differ from those of anaplastic carcinoma. Pleomorphic giant cells were admixed with the underlying thyroid carcinoma and constituted from 5% to 25% of the tumor. Cytologically, they had an abundant eosinophilic cytoplasm with large and irregular nuclei. Compared to pleomorphic giant cells of anaplastic carcinoma, they reproduced the growth pattern of the underlying carcinoma, had a low mitotic index without necrosis or inflammation, and were reactive with thyroglobulin and thyroid-specific transcription factor-1 and strongly and diffusely positive for cytokeratin AE1/AE3. After 16-84 months of follow-up, patients are relapse-free and still alive. These cases show that pleomorphic tumor giant cells arising in papillary thyroid carcinomas do not always represent dedifferentiation and progression to anaplastic carcinoma. Distinction among these processes is critical as their treatment and prognosis are very different.

    Full Text Available El carcinoma diferenciado de tiroides en quiste tirogloso (CaQT es una rara entidad. En diferentes series de pacientes operados por quistes tiroglosos su incidencia fue del 0.7 al 1.07%. Luego de la extirpación del quiste por el procedimiento de Sistrunk, no hay consenso sobre la indicación de tiroidectomía total, radioablación y/o terapéutica supresiva con levotiroxina. El objetivo del Departamento de tiroides de SAEM, fue evaluar: formas de presentación, evolución clínica, métodos diagnósticos de utilidad y tratamiento para consensuar futuras conductas. Material y Métodos: Estudio multicéntrico, retrospectivo en 22 pacientes entre 10 a 69 años, 15 mujeres y 7 varones. Resultados: El tamaño de los quistes osciló entre 1 y 8 cm (Mediana= 3.0 cm, Χ ± DS= 3.7 ± 2.2 cm. La mitad de los pacientes presentó crecimiento del quiste en los 6 meses previos a la cirugía. La punción resultó sospechosa en 2/5 quistes y positiva en uno. La ecografía tiroidea evidenció nódulos en 4/13 casos (30%. Se realizó tiroidectomía en 17/22 pacientes (total: 15 y subtotal: 2. La histología del CaQT demostró carcinoma papilar en 21 y carcinoma folicular en uno. Hubo coexistencia de cáncer intratiroideo en el 23.5% de los casos, ninguno multicéntrico. Dos pacientes presentaron metástasis ganglionares y otro tuvo compromiso muscular (ninguno de ellos coexistió con cáncer intratiroideo. Se radioablacionó a 13 pacientes. En 9/11 pacientes la tiroglobulina permaneció indetectable durante el seguimiento (1 a 14 años. Conclusiones: 1 Realizar ecografía de cuello y punción ecoguiada a todo paciente con quiste tirogloso. 2 En caso de CaQT combinar simultáneamente tiroidectomía total y procedimiento de Sistrunk. 3 Evaluar radioablación complementaria y tratamiento supresivo con levotiroxina en cada caso. 4 Efectuar el seguimiento tal como en los carcinomas ortotópicos.Differentiated thyroid carcinoma (DTC in thyroglosal duct cyst (TGDC is

    Background The treatment of hepatocellular carcinoma (HCC) is still a major health issue because of its increasing incidence and because of the complexity of its management. Transarterial embolization (TAE) and transarterial chemoembolization (TACE) are two widely used locoregional therapies in the treatment of HCC, especially for unresectable intermediate and advanced HCCs. Summary The modern use of TAE and TACE opens new scenarios for the treatment of unresectable HCC and has yielded interesting results. The present work describes the role of transarterial therapies for HCC and focuses on the different Western and Eastern approaches to the study of response predictors. Key Messages Recent refinements in interventional radiology techniques and in HCC patient selection have facilitated better local control of the disease. The molecular profiling of HCC to predict the response to TACE and TAE will greatly help clinicians identify the optimum therapy. PMID:27995085

    2011-01-01

    Worldwide, the burden of the non viral causes of hepatocellular carcinoma (HCC) is usually underestimated. Clearly industrial goods, tobacco, alcohol and processed foods are the agents of new epidemics in modern times which far outscore the burden of infectious agents on morbidity and mortality. Smoking, a dose-related contributing factor for HCC, receives too little attention in clinical practice. In France, tobacco, hepatitis B and C virus and alcohol are the main risk factors for HCC mortality (33%, 31% and 26%, respectively). In developing countries, where tobacco consumption is dramatically increasing, this epidemic may soon surpass hepatitis B. Obesity and diabetes are the contributing factors too. The role of industrial processed foods in the increase of the prevalence of obesity and diabetes cannot be ignored.

    After examining the literature on the subject, all patients aged over 60 and admitted to the Surgical Pathology Department of Pavia University from 1-1-1974 to 31-12-1985, suffering from gastric carcinoma have been considered. From the results obtained it is concluded that stomach cancer is a disease that preferentially affects the IIIrd age, usually occurring with atypical symptomatology that leads the patient to underestimate the seriousness of the disease, and impeding early diagnosis that would be effective for therapeutic purposes. It is therefore essential for the necessary examination to be carried out at the first warning symptoms. Further, the general state of these patients has to be controlled and appropriate treatment sought to treat the various accompanying conditions and so prepare the patient for operation.

    Full Text Available Anaplastic thyroid carcinoma is one of the most aggressive of all human malignant diseases. It has an unfavorable prognosis and responsible for most of the mortality and morbidity rates due to thyroid carcinomas. We present a case of incidental anaplastic thyroid carcinoma and discuss the epidemiology, biology, risk factors, prognostic factors of the disease and the approach to treatment, in the light of the current medical literature. The prognosis is much better in cases with incidental carcinoma compared to the classical type and surgical excision of the tumor has a favorable effect on the results. Our case was followed-up for 1.5 years with no evidence of recurrence or metastasis.

    Background The coagulation function in patients with pancreatic carcinoma is abnormal and the reason is not very clear. In this study, we retrospectively analyzed the coagulation function in patients with pancreatic carcinoma.Methods From June 2004 to December 2007, 132 patients received diagnosis and treatment in our hospital. The coagulative parameters including the prothrombin time, activated partial thromboplastin time, and fibrinogen levels were collected and studied retrospectively.Results The average fibrinogen levels in patients with pancreatic carcinoma, (476.21±142.05) mg/dl, were significantly higher than in patients with cholangiolithiasis, (403.28±126.41) mg/dl (P 0.05).Conclusions The level of fibrinogen in patients with pancreatic carcinoma was elevated. The elevated fibrinogen level may be associated with invasiveness and lymphatic metastasis. Using vitamin K in perioperation management did not reduce intraoperative blood loss.

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

    Fabio Luiz de Menezes Montenegro

    Full Text Available CONTEXT AND OBJECTIVE: Adequate management of parathyroid carcinoma apparently relates to the surgeon’s ability to identify it at the first operation. The objective of this paper was to evaluate the role of clinical suspicion in the management of parathyroid carcinoma. DESIGN AND SETTING: Retrospective analysis of parathyroid carcinoma patients treated in Department of Head and Neck Surgery, Faculdade de Medicina da Universidade de São Paulo. METHODS: Cross-sectional study of 143 patients who underwent surgery from 1995 to 2000, due to hyperparathyroidism. These cases were reviewed to ascertain whether preoperative and intraoperative suspicion of parathyroid carcinoma were helpful during the operation, and which factors demonstrated the suspicion of cancer best. RESULTS: Among 66 patients with primary hyperparathyroidism there were four cases of parathyroid carcinoma (6.1%, and one case was found in secondary hyperparathyroidism (1.3%. Palpable nodules were found in five patients with primary hyperparathyroidism, four of them with parathyroid carcinoma. Preoperative levels of calcium in primary hyperparathyroidism with cancer patients varied from 12.0 mg/dl to 18.2 mg/dl. Two patients had gross macroscopic spread of the tumor to adjacent structures. Except for one patient, with extensive disease, tumors were resected en bloc. In secondary hyperparathyroidism, parathyroid carcinoma was found in a fifth mediastinal gland. One atypical adenoma was observed. CONCLUSIONS: High levels of calcium, palpable tumors and adherence to close structures are more common in parathyroid carcinoma. These clinical signs may be helpful for decision-making during parathyroid surgery.

    Full Text Available Follicular cell-derived well-differentiated thyroid cancer, papillary (PTC and follicular thyroid carcinomas (FTC compose 95% of all thyroid malignancies. Familial follicular cell-derived well-differentiated thyroid cancers contribute to 5% of those cases. These familial follicular cell derived carcinomas or non-medullary thyroid carcinomas (NMTC divide into two clinical-pathological groups. One group, syndromic-associated, composed by predominately non-thyroidal tumors, is comprised of Pendred syndrome, Warner syndrome, Carney complex type 1, PTEN-hamartoma tumor syndrome (Cowden disease; PHTS, familial adenomatous polyposis (FAP/Gardner syndrome. Additionally other less established links correlated to the development of follicular cell-derived tumors have also included Ataxia-teleangiectasia syndrome, McCune Albright syndrome, and Peutz-Jeghers syndrome. The subsequent group encompasses syndromes typified by non-medullary thyroid carcinomas or NMTC, as well as, pure familial (f PTC with or without oxyphilia, fPTC with multinodular goiter and fPTC with papillary renal cell carcinoma. This heterogeneous group of diseases has not a established genotype-phenotype correlation as the well-known genetic events identified in the familial C-cell-derived tumors or medullary thyroid carcinomas (MTC. Clinicians should be have the knowledge to identify the likelihood of a patient presenting with thyroid cancer having an additional underlying familial syndrome stemming from characteristics through morphological findings that would alert the pathologist to have the patient undergo subsequent molecular genetics evaluations. This review will discuss the clinical and pathological findings of the patients with familial papillary thyroid carcinoma, such as familial adenomatous polyposis, Carney complex, Werner syndrome, and Pendred syndrome and the heterogeneous group of familial papillary thyroid carcinoma.

    2017-01-01

    Introduction Breast carcinoma is one of the most common malignancies affecting women in developing countries. Molecular studies of breast carcinoma have classified the tumour based on the immunohistochemical staining into 4 subtypes, such as Luminal A, Luminal B, HER2/neu Positive and Triple Negative Breast Carcinoma (TNBC). TNBCs are reported to have an aggressive behaviour and wide metastasis, leading to selective treatment outcomes. Aim The aim was to study the clinicopathological features such as age, site, tumour size, histopathological type, histologic grade, lymph node status, stage and treatment outcomes of triple negative breast carcinoma. Materials and Methods A retrospective study was conducted on 108 cases of breast carcinoma received during the period of 2 years. The tumour was classified based on immunohistochemical staining into four subtypes. The clinicopathological details, histomorphological and immunohistochemical features of TNBC were studied. Results Of the 108 patients, 34 patients were diagnosed as TNBC. The average age at presentation was 48 years. Most of the cases showed Nottingham Modification of Scarff Bloom-Richardson (NMBR) grade 3 (55.9%) and stage II (67.6%). Ly-mph node metastasis was seen in 50% of cases. Infiltrating ductal carcinoma (not otherwise specified) type (91.2%) was the most common histological type. Among the other subtypes, Luminal A carcinoma was the most common (36.1%), followed by TNBC (31.5%) and HER2/neu positive carcinomas (28.7%). Compared to the other types of tumours, TNBC showed the most frequent distant lymph node metastasis (50%) when compared to luminal A (38.5%), luminal B (25%), HER2/neu positive (48.4%). Unlike the other types of tumours, TNBC were mostly high-grade. Conclusion TNBC have an aggressive behaviour compared to other subtypes with higher NMBR grade, nuclear pleomorphism, high mitotic rate and lymph node metastasis. PMID:28273970

    GATA3 plays an integral role in breast luminal cell differentiation and is implicated in breast cancer progression. GATA3 immunohistochemistry is a useful marker of breast cancer; however, its use in specific subtypes is unclear. Here, we evaluate GATA3 expression in 86 invasive ductal carcinomas including triple-negative, Her-2, and luminal subtypes, in addition to 13 metaplastic carcinomas and in 34 fibroepithelial neoplasms. In addition, we report GATA3 expression in matched primary and metastatic breast carcinomas in 30 patients with known estrogen receptor (ER), progesterone receptor (PR), and Her-2 status, including 5 with ER and/or PR loss from primary to metastasis. Tissue microarrays containing 5 to 10 cores per tumor were stained for GATA3, scored as follows: 0 (0-5%), 1+ (6%-25%), 2+ (26%-50%), 3+ (51%-75%), and 4+ (>75%). GATA3 labeling was seen in 67% (66/99) of primary ductal carcinomas including 43% of triple-negative and 54% of metaplastic carcinomas. In contrast, stromal GATA3 labeling was seen in only 1 fibroepithelial neoplasm. GATA3 labeling was seen in 90% (27/30) of primary breast carcinomas in the paired cohort, including 67% of triple-negative carcinomas. GATA3 labeling was overwhelmingly maintained in paired metastases. Notably, GATA3 was maintained in all "luminal loss" metastases, which showed ER and/or PR loss. In conclusion, GATA3 expression is maintained between matched primary and metastatic carcinomas including ER-negative cases. GATA3 can be particularly useful as a marker for metastatic breast carcinoma, especially triple-negative and metaplastic carcinomas, which lack specific markers of mammary origin. Finally, GATA3 labeling may help distinguish metaplastic carcinoma from malignant phyllodes tumors.

  3. Salivary duct carcinoma of the parotid gland

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Salivary duct carcinoma of the parotid gland is an uncommon tumor, highly aggressive. About 200 cases have been reported in the English literature. Pathomorphologically, these tumors showed great similarities to ductal carcinoma of the female breast, which is why they described this tumor as "salivary duct carcinoma." The authors describe a new case of salivary duct carcinoma of the parotid gland. We present the case of a 50-year-old patient with progressive facial paralysis. The MRI examination of the head showed two ill-defined formations. A malignant tumor was strongly suspected, so that a total left parotidectomy with excision of the adjacent facial nerve and left lymph node dissection was performed. Microscopic examination concluded to a salivary duct carcinoma of the left parotid gland negative with Her2/neu antibody with lymph node metastasis. There were no recurrences or metastases within 3 years of follow-up. Salivary duct carcinoma of the parotid gland is a rare tumor with an aggressive behavior. This is due to its propensity to infiltrate distant organs. The diagnosis is based on microscopic examination. Treatment modalities are non-consensual, but some authors advocate the necessity of aggressive approach, especially in tumors negative with Heur2/neu antibody. This is due to the fact that the overexpression of this antigen was reported to be associated with a poor prognosis.

    The prevalence at death of carcinoma of the lung in miners and ex-miners has been compared in those with and without pneumoconiosis at necropsy. The prevalence of 11.4% in the group as a whole is no greater than that in the male population in North-west England. Carcinoma of the lung was present in 62 (13.1%) of those without pneumoconiosis and in 52 (9.8%) of those with pneumoconiosis. The mean age at death of those with pneumoconiosis was 71.3 years so that they cannot be said to have died before the age at which they would have developed carcinoma. Those with progressive massive fibrosis whose mean age at death was 72 years had the lowest prevalence of carcinoma of the lung at all ages--8.4%. For reasons stated in the text this is inevitably a biased sample. The number of those without pneumoconiosis is probably lower than the true figure because the deaths of miners and ex-miners in whom there is no suspicion of lung disease may not have been reported to the coroner or to the pneumoconiosis medical panel. There appears to be no positive link between carcinoma of the lung and pneumoconiosis. There is a surprisingly high number of smokers and ex-smokers among these miners, and this appears to have more relevance to the prevalence of carcinoma of the lung than does pneumoconiosis.

    Cervical cancer is responsible for 10–15% of cancer-related deaths in women worldwide1,2. The etiological role of infection with high-risk human papilloma viruses (HPV) in cervical carcinomas is well established3. Previous studies have implicated somatic mutations in PIK3CA, PTEN, TP53, STK11 and KRAS4–7 as well as several copy number alterations in the pathogenesis of cervical carcinomas8,9. Here, we report whole exome sequencing analysis of 115 cervical carcinoma-normal paired samples, transcriptome sequencing of 79 cases and whole genome sequencing of 14 tumor-normal pairs. Novel somatic mutations in 79 primary squamous cell carcinomas include recurrent E322K substitutions in the MAPK1 gene (8%), inactivating mutations in the HLA-B gene (9%), and mutations in EP300 (16%), FBXW7 (15%), NFE2L2 (4%) TP53 (5%) and ERBB2 (6%). We also observed somatic ELF3 (13%) and CBFB (8%) mutations in 24 adenocarcinomas. Squamous cell carcinomas had higher frequencies of somatic mutations in the Tp*C dinucleotide context than adenocarcinomas. Gene expression levels at HPV integration sites were significantly higher in tumors with HPV integration compared with expression of the same genes in tumors without viral integration at the same site. These data demonstrate several recurrent genomic alterations in cervical carcinomas that suggest novel strategies to combat this disease. PMID:24390348

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    A 51-year-old woman had a 35 mm circumscribed calcified lesion identified on screening mammography, designated R4. Excision showed a fibroadenoma with multiple foci of lobular neoplasia (atypical lobular hyperplasia and classical lobular carcinoma in situ [LCIS]). A focus of microinvasive lobular carcinoma (MILC) was also present, confirmed on immunohistochemistry. The MILC cells were ER positive, Her-2-negative, and e-cadherin negative. Microinvasive carcinoma, defined as "invasive carcinoma with no focus measuring >1 mm" (TNM UICC 7th edition) is usually encountered in ductal carcinoma in situ but may occur with classical, florid, or pleomorphic LCIS. In one series MILC constituted 0.4% of all invasive lobular carcinomas and was present in 0.4% of all LCIS. MILC is a histologically subtle lesion, the identification of which lends further weight to the concept of lobular neoplasia as a precursor lesion. MILC has been observed in hamartoma but, to our knowledge, has not previously been reported in fibroadenoma.

    Pancreatic mucinous noncystic (colloid) carcinomas (MNCC) differ from the usual ductal adenocarcinomas in their mucin expression profile and share with many extrapancreatic mucinous carcinomas the expression of MUC2. Because mucinous carcinomas are frequently associated with mutations of the DNA mismatch repair genes, causing them to exhibit the so-called mutator phenotype, we decided to investigate whether MNCCs of the pancreas are characterized by microsatellite instability (MSI). Twelve carcinomas with a mucinous phenotype (8 mucinous noncystic carcinomas, 3 intraductal papillary-mucinous carcinomas with an invasive muconodular component, and 1 ductal adenocarcinoma with an extensive mucinous noncystic component) and 11 ductal adenocarcinomas were immunostained with monoclonal antibodies to the mismatch repair gene products hMLH1, hMSH2, and hMSH6. For MSI analysis, DNA was isolated from microdissected tissue, and five primary microsatellites (BAT 25, BAT 26, D5S346, D17S250, and D2S123) were analyzed. MSI was diagnosed in case a novel allele was found, compared with the normal tissue. The criterion for LOH was a 75% signal reduction. All carcinomas tested exhibited nuclear expression of mismatch repair gene products, except for one MNCC that also showed MSI at the molecular level. The data suggest that pancreatic carcinomas with a mucinous phenotype (MUC2+/MUC1-) do not appear to normally exhibit mutations in the mismatch repair genes and therefore differ in their carcinogenesis from those in other organs.

    High-grade endometrial carcinomas are a heterogeneous group of tumors and include grade 3 endometrioid (EC-3), serous (SC), and clear cell carcinomas (CCC). There are conflicting data about the prognosis of these subtypes of high-grade endometrial carcinoma; this may be a result of lack of reproducibility in classifying tumor cell type. The purpose of this study was to examine differences in immunophenotype and outcome in a series of high-grade endometrial carcinomas, focusing on the comparison of EC-3 versus SC. We selected 180 endometrial carcinomas of SC, EC, or CCC type. No mixed carcinomas were included in the study. We chose the following immunohistochemical markers, estrogen receptor (ER), insulin-like growth factor 2 mRNA-binding protein 3 (IMP3), p16, p53, progesterone receptor (PR), and phosphatase and tensin homolog (PTEN) as being significantly differentially expressed in endometrial carcinoma subtypes. The tumors were stratified into 4 groups on the basis of their cell type and grade: EC grade 1 or 2, EC-3, SC, and CCC. Univariate survival analysis revealed significant differences in outcome between the 4 groups (Pcarcinomas have a significantly better prognosis than SC carcinomas of the endometrium.

    2012-08-01

    NUT midline carcinoma (NMC) is a highly lethal tumor defined by translocations involving the NUT gene on chromosome 15q14. NMC involves midline structures including the sinonasal tract, but its overall incidence at this midline site and its full morphologic profile are largely unknown because sinonasal tumors are not routinely tested for the NUT gene translocation. The recent availability of an immunohistochemical probe for the NUT protein now permits a more complete characterization of sinonasal NMCs. The archival files of The Johns Hopkins Hospital Surgical Pathology were searched for all cases of primary sinonasal carcinomas diagnosed from 1995 to 2011. Tissue microarrays were constructed, and NUT immunohistochemical analysis was performed. All NUT-positive cases underwent a more detailed microscopic and immunohistochemical analysis. Among 151 primary sinonasal carcinomas, only 3 (2%) were NUT positive. NUT positivity was detected in 2 of 13 (15%) carcinomas diagnosed as sinonasal undifferentiated carcinoma and in 1 of 87 (1%) carcinomas diagnosed as squamous cell carcinoma. All occurred in men (26, 33, and 48 y of age). The NMCs grew as nests and sheets of cells with a high mitotic rate and extensive necrosis. Two were entirely undifferentiated, and 1 tumor showed abrupt areas of squamous differentiation. Each case had areas of cell spindling, and 2 were heavily infiltrated by neutrophils. Immunohistochemical staining was observed for cytokeratins (3 of 3), epithelial membrane antigen (3 of 3), p63 (2 of 3), CD34 (1 of 3), and synaptophysin (1 of 3). All patients died of the disease (survival time range, 8 to 16 mo; mean, 12 mo) despite combined surgery and chemoradiation. NMC represents a rare form of primary sinonasal carcinoma, but its incidence is significantly increased in those carcinomas that exhibit an undifferentiated component. Indiscriminant analysis for evidence of the NUT translocation is unwarranted. Instead, NUT analysis can be restricted to

    Full Text Available Abstract Background The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. Materials and methods Fifty three paraffin blocks of different lesions (15 muco-epidermoid carcinoma, 14 adenoid cystic carcinoma, 3 epi-myoepithelial carcinoma, 5 salivary duct carcinoma, 5 malignant pleomorphic adenoma, 6 polymorphous low grade adenocarcinoma and 5 acinic cell carcinoma were prepared for immunohistochemical staining with maspin and MCM2 antibodies. ANOVA and Pearson correlation tests were used for the statistical analysis of the results. Results All salivary gland carcinomas express maspin and MCM2 with variable cellular localization. There was a significant difference in the expression of each antibody between mucoepidermoid carcinoma, adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. No association was found between examined markers and lymph node metastasis. Conclusions Salivary gland carcinomas express maspin and MCM2 with variable levels and cellular localization, consisting important markers of biological behavior in these tumors. The level of MCM2 expression can be used in the differential diagnosis of adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. Further study with large sample size is recommended to assess their value in prediction of lymph node metastasis.

    An increase in the prevalence of obesity and diabetes mellitus has been associated with the rise in non-alcoholic fatty liver disease(NAFLD). Two-thirds of the obese and diabetic populations are estimated to develop NAFLD. Currently, NAFLD is the most common etiology for chronic liver disease globally. The clinical spectrum of NAFLD ranges from simple steatosis, an accumulation of fat greater than 5% of liver weight, to nonalcoholic steatohepatitis(NASH), a more aggressive form with necroinflammation and fibrosis. Among the patients who develop NASH, up to 20% may advance to cirrhosis and are at risk for complications of end-stage liver disease. One of the major complications observed in patients with NASH-related cirrhosis is hepatocellular carcinoma(HCC), which has emerged as the sixth most common cancer and second leading etiology of cancer-related deaths worldwide. The incidence of HCC in the United States alone has tripled over the last three decades. In addition, emerging data are suggesting that a small proportion of patients with NAFLD may be at higher risk for HCC in the absence of cirrhosis - implicating obesity and diabetes mellitus as potential risk factors for HCC.

    Pancreatic cancer (PC) is the most fatal of all gastrointestinal cancers, wherein its mortality compares strikingly with its incidence. Unfortunately, 80-90% of PCs are diagnosed in the nonresectable stage. While the lifetime risk of PC in developed countries is approximately 1-3%, it is the fifth most common cause of cancer deaths among both males and females in Western countries. It occurs in excess in Jews. Approximately 5-10% of PC shows familial clustering. Examination of such familial clusters must take into consideration cancers of diverse anatomic sites, such as malignant melanoma in the familial atypical multiple melanoma (FAMMM) syndrome due to the CDKN2A (p16) germline mutation, and combinations of colorectal and endometrial carcinoma, ovarian carcinoma, and several other cancers in hereditary nonpolyposis colorectal cancer (HNPCC), which are due to mismatch repair germline mutations, the most common of which are MSH2 and MLH1 . Other hereditary disorders predisposing to PC include Peutz-Jeghers syndrome, due to the STK11 mutation, familial pancreatitis due to the cationic trypsinogen gene, site-specific familial pancreatic cancer which may be due to the 4q32-34 mutation, hereditary breast-ovarian cancer (HBOC) syndrome that is due to BRCA2 and possibly some families with HBOC that is due to BRCA1 , familial adenomatous polyposis due to the ATP gene, and ataxia telangiectasia due to the ATM germline mutation. This extant heterogeneity mandates that the physician be knowledgeable about these PC-prone syndromes which play such an important role when considering the differential diagnosis of hereditary PC. Unfortunately, there are no PC screening programs with acceptable sensitivity and specificity. However, the gold standard for screening at this time is endoscopic ultrasound. Clearly, there is a great need for the development of novel screening approaches with acceptable sensitivity and specificity. Further research is needed to elucidate those etiologic

    The pancreas is an unusual site for tumor metastasis, accounting for only 2% to 5% of all malignancies affecting the pancreas. The more common metastases affecting the pancreas include renal cell carcinomas, melanomas, colorectal carcinomas, breast carcinomas, and sarcomas. Although pancreatic involvement by nonrenal malignancies indicates widespread systemic disease, metastatic renal cell carcinoma to the pancreas often represents an isolated event and is thus amenable to surgical resection, which is associated with long-term survival. As such, it is important to accurately diagnose pancreatic involvement by metastatic renal cell carcinoma on histology, especially given that renal cell carcinoma metastasis may manifest more than a decade after its initial presentation and diagnosis. In this review, we discuss the clinicopathologic findings of isolated renal cell carcinoma metastases of the pancreas, with special emphasis on separating metastatic renal cell carcinoma and its various differential diagnoses in the pancreas.

    2012-12-01

    Hepatocyte nuclear factor 1-beta (HNF1β) has recently emerged as a relatively sensitive and specific marker for ovarian clear cell carcinoma. The purpose of this study is to assess the diagnostic utility of this marker for endometrial clear cell carcinoma. Immunohistochemical analysis was performed on 75 endometrial tissues using a goat polyclonal antibody raised against a peptide mapping at the C-terminus of human HNF1β protein. The 75 cases included 15 clear cell carcinomas, 20 endometrioid carcinomas, 15 endometrial serous carcinomas/uterine papillary serous carcinomas, 20 cases of normal endometrium, 2 cases of clear cell metaplasia, and 3 cases of Arias Stella reaction. Staining interpretations were based on a semiquantitative scoring system, a 0 to 12+ continuous numerical scale that was derived by multiplying the extent of staining (0 to 4+ scale) by the intensity of staining (0 to 3+ scale) for each case. HNF1β expression was found to be present in a wide spectrum of tissues. Twenty-seven (54%) of the 50 carcinomas displayed at least focal nuclear HNF1β expression, including 11 (73%) of 15, 9 (60%) of 15, and 7 (35%) of 20 clear cell, serous, and endometrioid carcinomas, respectively. The average nuclear staining scores for clear cell carcinomas, endometrioid carcinomas, and serous carcinomas were 5.2, 1.4, and 4.1, respectively. Clear cell carcinomas and endometrioid carcinomas displayed statistically significant differences regarding their nuclear staining scores (P = 0.0027), but clear cell carcinomas and endometrial serous carcinomas did not (P = 0.45). The calculated sensitivity of any nuclear HNF1β expression in classifying a carcinoma as being of the clear cell histotype was 73%, whereas the specificity was 54%. Nineteen of 20 normal endometrium samples displayed at least focal nuclear expression of HNF1β, and this expression was often diffuse. The 5 cases of benign histologic mimics of clear cell carcinomas (Arias Stella reaction and clear

    Mucinous carcinomas are a rare entity accounting for up to 2% of all breast cancers, which have been shown to display a gene expression profile distinct from that of invasive ductal carcinomas of no special type (IDC-NSTs). Here, we have defined the genomic aberrations that are characteristic of this special type of breast cancer and have investigated whether mucinous carcinomas might constitute a genomic entity distinct from IDC-NSTs. Thirty-five pure and 11 mixed mucinous breast carcinomas were assessed by immunohistochemistry using antibodies against oestrogen receptor (ER), progesterone receptor, HER2, Ki67, cyclin D1, cortactin, Bcl-2, p53, E-cadherin, basal markers, neuroendocrine markers, and WT1. Fifteen pure mucinous carcinomas and 30 grade- and ER-matched IDC-NSTs were microdissected and subjected to high-resolution microarray-based comparative genomic hybridization (aCGH). In addition, the distinct components of seven mixed mucinous carcinomas were microdissected separately and subjected to aCGH. Pure mucinous carcinomas consistently expressed ER (100%), lacked HER2 expression (97.1%), and showed a relatively low level of genetic instability. Unsupervised hierarchical cluster analysis revealed that pure mucinous carcinomas were homogeneous and preferentially clustered together, separately from IDC-NSTs. They less frequently harboured gains of 1q and 16p and losses of 16q and 22q than grade- and ER-matched IDC-NSTs, and no pure mucinous carcinoma displayed concurrent 1q gain and 16q loss, a hallmark genetic feature of low-grade IDC-NSTs. Finally, both components of all but one mixed mucinous carcinoma displayed similar patterns of genetic aberrations and preferentially clustered together with pure mucinous carcinomas on unsupervised clustering analysis. Our results demonstrate that mucinous carcinomas are more homogeneous between themselves at the genetic level than IDC-NSTs. Both components of mixed mucinous tumours are remarkably similar at the

    Hepatocellular carcinoma (HCC) is the second mostcommon cause of death from cancer worldwide.Standard potentially curative treatments are eitherresection or transplantation. The aim of this paper isto provide an overview of the surgical managementof HCC, as well as highlight current issues in hepaticresection and transplantation. In summary, due to therelationship between HCC and chronic liver disease,the management of HCC depends both on tumourrelatedand hepatic function-related considerations. Assuch, HCC is currently managed largely through nonsurgicalmeans as the criteria, in relation to the aboveconsiderations, for surgical management is still largelyrestrictive. For early stage tumours, both resectionand transplantation offer fairly good survival outcomes(5 years overall survival of around 50%). Selectiontherefore would depend on the level of hepatic functionderangement, organ availability and local expertise.Patients with intermediate stage cancers have limitedoptions, with resection being the only potential forcure. Otherwise, locoregional therapy with transarterialchemoembolization or radiofrequency ablation are viableoptions. Current issues in resection and transplantationare also briefly discussed such as laparoscopic resection,ablation vs resection, anatomical vs non-anatomicalresection, transplantation vs resection, living donor livertransplantation and salvage liver transplantation.

    The onset of hepatocellular carcinoma (HCC) is related to the development of non-neoplastic liver disease, such as viral infections and cirrhosis. Even though patients with chronic liver diseases undergo clinical surveillance for early diagnosis of HCC, this cancer is often diagnosed in advanced stage. In this case locoregional treatment is not possible and systemic therapies are the best way to control it. Until now sorafenib, a Raf and multi-kinase inhibitor has been the best, choice to treat HCC systemically. It showed a survival benefit in multicenter phase III trials. However the proper patient setting to treat is not well defined, since the results in Child-Pugh B patients are conflicting. To date various new target drugs are under developed and other biological treatments normally indicated in other malignancies are under investigation also for HCC. These strategies aim to target the different biological pathways implicated in HCC development and progression. The target drugs studied in HCC include anti-VEGF and anti-EGFR monoclonal antibodies, tyrosine kinase inhibitors and mTOR inhibitors. The most important challenge is represented by the best integration of these drugs with standard treatments to achieve improvement in overall survival and quality of life.

    BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most frequent primary malignant tumors in the world. Hepatic resection and liver transplantation are considered optimal for potential treatment of HCC. However, only 20%of HCCs can be surgically treated. And most of surgically-noneligible patients have to receive interventional managements including local ablation and transarterial chemoembolization (TACE). In this paper, we review the interventional treatments of HCC. DATA SOURCES:A literature search of PubMed database was conducted and research articles were reviewed. RESULTS: Percutaneous ethanol injection (PEI) is usually applied to small HCC for a complete necrosis. Radiofrequency ablation, an alternative to PEI, also causes tumor necrosis and needs fewer times of ablation. Other methods such as acetic acid injection, laser, microwave, etc have enriched local ablation for HCC. High intensity focus ultrasound (HIFU) is thought to be promising. TACE, another common modality, can improve the survival rate of patients with HCC. The newly developed embolic agents and adjuvant rAd-p53 gene therapy are well reported. CONCLUSIONS:Surgically-noneligible HCC can be treated with interventional procedures. Each method has its advantages and disadvantages. However, it is still pressing to develop ablative methods as well as new embolic agents for a better prognosis of HCC.

    Objective: To investigate the expression of PTEN in endometrial carcinoma and its clinical significance. Methods: Reverse transcriptase-polymerase chain reaction and Western-blot methods were used to detect PTEN expression in 28 cases of endometrial carcinoma. Results: mRNA and protein expression levels of PTEN in endometrial carcinomas were significantly lower than those in normal endometrium (P<0.01). Conclusion: PTEN may play an important role in the tumorigenesis of endometrial carcinoma.

    A carcinoma arising in a fibroadenoma is a rare event, which often entails a diagnostic challenge. The most common type is the lobular carcinoma and secondary a ductal carcinoma. We present an extremely rare case of malignant development of an invasive apocrine carcinoma in a complex fibroadenoma and underline the importance for clinicians to recognize the possibility of benign and malignant co-existence especially in older women.

  11. Epstein-Barr Virus in Gastric Carcinoma

    Jun Nishikawa

    2014-11-01

    Full Text Available The Epstein-Barr virus (EBV is detected in about 10% of gastric carcinoma cases throughout the world. In EBV-associated gastric carcinoma, all tumor cells harbor the clonal EBV genome. Gastric carcinoma associated with EBV has distinct clinicopathological features, occurs predominately in men and in younger-aged individuals, and presents a generally diffuse histological type. Most cases of EBV-associated gastric carcinoma exhibit a histology rich in lymphocyte infiltration. The immunological reactiveness in the host may represent a relatively preferable prognosis in EBV-positive cases. This fact highlights the important role of EBV in the development of EBV-associated gastric carcinoma. We have clearly proved direct infection of human gastric epithelialcells by EBV. The infection was achieved by using a recombinant EBV. Promotion of growth by EBV infection was observed in the cells. Considerable data suggest that EBV may directly contribute to the development of EBV-associated GC. This tumor-promoting effect seems to involve multiple mechanisms, because EBV affects several host proteins and pathways that normally promote apoptosis and regulate cell proliferation.

    Full Text Available Urachal carcinoma is rare comprising less than 1% of all bladder carcinomas. Metastases of urachal carcinoma have been reported to meninges, brain, ovary, lung, and maxilla. Cytologic features of metastatic urachal carcinoma have not been previously reported. We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to those in the previous resection specimen and concurrent biopsy. This is the first case report of bronchial brushings containing metastatic urachal carcinoma. No specific immunohistochemical profile is available for its diagnosis. The consideration of a second primary was a distinct possibility in this case due to the lapse of time from primary resection, absence of local disease, and lack of regional metastases.

    Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

    Full Text Available BACKGROUND: Despite the extensive research for many years throughout the world, the etiopathogenesis of cancer still remains obscure. For the early detection of carcinoma of various origins, a number of biochemical markers have been studied to evaluate the malignancy. AIM: To analyse serum gamma glutamyl transpeptidase (GGTP, lactate dehydrogenase (LDH and superoxide dismutase (SOD in carcinoma breast patients. SETTINGS & DESIGN: The serum biochemical markers were estimated in twenty five histopathologically confirmed patients with carcinoma breast and equal number of healthy age- matched individuals served as control. MATERIAL & METHODS: Serum gamma glutamyl transpeptidase (GGTP, lactate dehydrogenase (LDH and superoxide dismutase (SOD were estimated and their sensitivity determined. Statistics: Data was analysed with student′s ′t′-test and sensitivity score of these markers was determined. RESULTS & CONCLUSIONS: The mean serum GGTP, LDH and SOD activities in patients with carcinoma breast were tremendously increased as compared to controls, and a steady increase was observed in their activities from stage I through stage IV as well as following distant metastasis. Serum GGTP, LDH and SOD might prove to be most sensitive biomarkers in carcinoma breast in early detection of the disease.

    From 1983 to 1998, 93 patients with hypopharyngeal carcinoma were treated at Sapporo Medical University Hospital. Piriform sinus carcinoma was the most unfavorable prognostic location among the subsites. Also, the prognosis of patients with positive cervical lymph nodes and/or stage IV was poor. Forty-nine patients with N2 piriform sinus carcinoma were analyzed. Eleven (22.4%) had double cancers. Early T stages were curable with radiotherapy. However, the patients with positive cervical lymph nodes must be treated with radical neck dissection. Patients with good response at the time of 40 Gy had better survival rate than those with poor response. (author)

    2009-01-01

    BACKGROUND: Carcinoid of the gallbladder is rare. Since it often presents as a gallbladder mass it may be confused with gallbladder carcinoma. METHODS: A 35-year-old lady presented with pain in the right upper abdomen, and was radiologically found to have a gallbladder mass. A provisional diagnosis of gallbladder carcinoma was made. Laparotomy revealed a 20×20 cm, exophytic, friable growth arising from the fundus of the gallbladder. It was excised with segmentⅣb andⅤ of the liver and regional lymphadenectomy. RESULT: Histopathological examination revealed it was a neuroendocrine carcinoma, atypical carcinoid of the gallbladder. CONCLUSION: Gallbladder carcinoid has a poor outcome, requires aggressive treatment, and should be considered as one of the rare but possible gallbladder lesions.

    Canine prostatic tumours exhibit similarities to those of man and may represent a useful model system to explore the mechanisms of cancer progression. Tumour progression to malignancy requires a change from an epithelial phenotype to a fibroblastic or mesenchymal phenotype. Vimentin expression...... is associated with the invasive phenotype of human prostate cancer cells. The aim of the present study was to characterize immunohistochemically the expression of vimentin by canine prostatic carcinomas. Primary carcinomas and metastatic tumour foci both showed vimentin expression. This finding suggests...... that the acquisition of the epithelial-mesenchymal transition phenotype in canine prostatic carcinoma may be characterized by the presence of mesenchymal intermediate filament (vimentin) that could lead to a higher likelihood of metastasis....

    Lowe, D G

    1988-04-01

    Massive local eosinophilia of 100 or more eosinophils per high power field was found in 3.2% cases of invasive carcinoma of the cervix. The prevalence, length of history before presentation to surgery and histological features were similar in patients from Great Britain and Malawi, but in both populations the mean age at diagnosis was lower than in patients with cervical carcinomas without tissue eosinophilia. In some of the tumours, the malignant cells were very difficult to find because of the eosinophil infiltrate, and misinterpretation as an inflammatory lesion was possible. In the absence of circulating eosinophilia, cervical carcinomas with massive eosinophilia were found to have a better prognosis than tumours without. Five patients had circulating eosinophilia as well as local tumour eosinophil infiltration, and each of them had extensive tumour spread.

    Primary intraosseous carcinoma (PIOC) is a rare odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium. A 56-year-old patient who complained of delayed healing after extraction of upper left central incisor visited our department. The conventional radiographs showed a bony destructive lesion with ill-defined margin and moth-eaten appearance. On the computed tomographic images, the lesion perforated the labial cortex of alveolar bone, elevated the left nasal floor superiorly, and perforated partially both nasal floor. The magnetic resonance images showed low signal intensity at T2 and T1 weighted images at the area and adjacent soft tissue. Histologically, there were irregular epithelial islands with cell atypia, nuclear hyperchromatism, pleomorphism, atypical mitosis. The final diagnosis was PIOC.

    NUT carcinoma (NC) is a recently described, rare and extremely aggressive cancer primarily located to supradiaphragmatic structures and affecting young individuals. NC is characterized by translocations involving the NUT gene on 15q14 with the most common translocation partner gene being BRD4 on 19......p13, resulting in the t(15;19)(q14;p13) karyotype. NC is poorly differentiated and is likely to be overlooked and misdiagnosed as poorly differentiated squamous cell carcinoma (SCC) when immunohistochemical evaluation of NUT protein expression is omitted. Previously, NC has been found in the parotid...... and submandibular glands and we present the first case in the sublingual gland arising in a 40-year-old woman. We discuss the diagnostic considerations for poorly differentiated carcinomas of the salivary glands and advocate the inclusion of NUT immunohistochemistry in this setting. Not only does the NC diagnosis...

    Breast metastases from extramammary neoplasms are very rare. We presented a 66 year-old female with metastasis of small cell lung carcinoma to the breast. She presented with consolidation over the left upper lobe of her lung undetermined after endobronchial or video-assisted thoracoscopic surgery (VATS) biopsy, and this was treated effectively after antibiotic therapy at initial stage. The left breast lumps were noted 4 months later, and she underwent a modified radical mastectomy under the impression of primary breast carcinoma. However, the subsequent chest imaging revealed re-growing mass over the left mediastinum and hilum, and cells with the same morphological and staining features were found from specimens of transbronchial brushing and biopsy. An accurate diagnosis to distinguish a primary breast carcinoma from metastatic one is very important because the therapeutic planning and the outcome between them are different.

    Full Text Available Large-cell neuroendocrine carcinomas of the lung are extremely rare. There are difficulties related to the diagnosis and treatment and there are no consensus because of the small number of studies. 65-year-old male patient presented with hemoptysis. Chest X-ray and thoracic computorized tomography scan showed a mass lesion and it could not be diagnosed by bronchoscopic biopsy and lavage. Lobectomy was performed due to the high value of standardized uptake value in positron emission tomography. Large cell neuroendocrine carcinoma was diagnosed with pathological evaluation and immunohistochemical study and after 20-month follow-up there was no recurrence. The diagnosis, treatment, and prognosis of large cell neuroendocrine carcinoma in the light of the literature is presented.

    Parathyroid carcinoma is a rare endocrine malignancy accounting for 0.5% to 4.0% of all cases of hyperparathyroidism and commonly present as hypercalcemia and parathyroid hormone (PTH) elevation. Nonfunctional parathyroid carcinoma does not show symptoms of hyperparathyroidism and only showed a vague indication of being pathologic, even when detected late. The optimal treatment is en bloc resection of the cancer, but frequent local recurrence after surgery has been reported. Adjuvant local treatment such as radiotherapy may improve the likelihood local control in cases with incompletely resected or microscopic residual tumor. The results of this study point to a case of nonfunctional parathyroid carcinoma treated by external beam radiotherapy after en-bloc resection of cancer.

    A 32 year Libyan male presented with the complaints of headache and diplopia. He was diagnosed with a cavernous sinus meningioma on the basis of MRI findings but no initial biopsy was taken. Depending on the radiologic diagnosis the patient was treated with gamma knife surgery twice, abroad. During follow up he developed left ear deafness and left cervical lymph adenopathy. An ENT evaluation with biopsy from the nasopharynx and cervical lymph node was taken. The histopathologic diagnosis of the resected tumour showed a nasopharyngeal carcinoma with cervical lymph node metastasis (poorly differentiated lympho-epithelial carcinoma). The cavernous sinus tumour which was initially treated as a meningioma was in fact metastasis from the nasopharyngeal carcinoma, making this an interesting and rare occurrence.

    2003-10-01

    HLA class I molecules are frequently lost in a large variety of human carcinomas, possibly because of T-cell immune selection of major histocompatibility complex class I deficient tumor variants. We report that this phenomenon is also a frequent event in bladder carcinomas. Of a total of 72 bladder carcinomas, 72% of the tumors had at least one alteration in HLA class I expression. These altered HLA class I phenotypes were classified as total HLA class I loss (25%; phenotype I); HLA-A or/and HLA-B locus-specific loss (12%; phenotype III); and HLA class I allelic loss (35%; phenotype II or IV). Comparison of histopathological parameters with HLA class I expression showed a statistically significant relationship with the degree of differentiation and tumor recurrence.

  17. Primary prevention of hepatocellular carcinoma.

    Science.gov (United States)

    1995-01-01

    Hepatocellular carcinoma (HCC) is one of the major cancers in China. Accordingly, the mortality rates in 1990 (per 100,000) were 20.10 in certain cities and 24.32 in certain counties. More than 90% of HCC cases and 70% of controls were infected with the hepatitis B virus (HBV) (Odds Ratio (OR) = 10-50). In the same group of patients, 8-27% of those with HCC and 0-11% of the healthy controls were also infected with hepatitis C (HCV) (OR = 2.11-17.29). There appears to be some correlation between HBV markers and the OR. The government requires that 85% of infants be immunized with HBV vaccine. In 1992, there were 3 million infants inoculated with HB vaccines. Aflatoxins have been found as contaminants in food, particularly in corn, peanut oil, soya sauce and fermented soya beans. The intake of aflatoxin B1 (AFB1) by people of ten different villages correlated with HCC mortality rates (r = 0.55; P aflatoxins. These adducts are higher in hyperendemic HCC areas and cases. Most people have now changed their staple food and eat rice instead of corn. Six large epidemiological studies have confirmed that people who drink pond-ditch water experience higher HCC mortality rates than people who drink deep-well water. Recent research has found that the blue-green algal toxin microcystin (MCYST) was a contaminant of pond-ditch water. MCYST is a strong promoter of HCC and will induce severe intrahepatic haemorrhages and liver necrosis. More than 80% of people in Qidong County have already changed their sources of water from pond-ditches to deep wells. Therefore, a combined strategy of the prevention of hepatitis, control of crops and control of drinking water is advocated for the primary prevention of HCC in China.

  18. Hepatocellular carcinoma: Therapy and prevention

    2005-01-01

    Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. The major etiologies and risk factors for the development of HCC are well defined and some of the multiple steps involved in hepatocarcinogenesis have been elucidated in recent years. Despite these scientific advances and the implementation of measures for the early detection of HCC in patients at risk, patient survival has not improved during the last three decades. This is due to the advanced stage of the disease at the time of clinical presentation and limited therapeutic options. The therapeutic options fall into five main categories: surgical interventions including tumor resection and liver transplantation, percutaneous interventions including ethanol injection and radiofrequency thermal ablation, transarterial interventions including embolization and chemoembolization, radiation therapy and drugs as well as gene and immune therapies. These therapeutic strategies have been evaluated in part in randomized controlled clinical trials that are the basis for therapeutic recommendations. Though surgery, percutaneous and transarterial interventions are effective in patients with limited disease (1-3 lesions, <5 cm in diameter) and compensated underlying liver disease (cirrhosis Child A), at the time of diagnosis more than 80% patients present with multicentric HCC and advanced liver disease or comorbidities that restrict the therapeutic measures to best supportive care. In order to reduce the morbidity and mortality of HCC, early diagnosis and the development of novel systemic therapies for advanced disease, including drugs, gene and immune therapies as well as primary HCC prevention are of paramount importance. Furthermore, secondary HCC prevention after successful therapeutic interventions needs to be improved in order to make an impact on the survival of patients with HCC. New technologies, including gene expression profiling and proteomic analyses, should allow to further

    Full Text Available Primary pancreatic small cell carcinoma (SCC is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions’ experience with resectable pancreatic SCC. Six patients with pancreatic SCC treated at the Johns Hopkins Hospital (4 patients and the Mayo Clinic (2 patients were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data were analyzed, and the literature on pancreatic SCC was reviewed. Median age at diagnosis was 50 years (range 27-60. All six tumors arose in the head of the pancreas. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There were no perioperative deaths and three patients had at least one postoperative complication. All six patients received adjuvant therapy, five of whom were given combined modality treatment with radiation, cisplatin, and etoposide. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed favorable survival rates when compared to prior reports of both resected and unresectable SCC. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation.

    Hepatocellular carcinoma(HCC)is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths.Most HCC are associated withwell known underlying risk factors,in fact,HCC arise in cirrhotic patients in up to 90%of cases,mainly due to chronic viral hepatitis and alcohol abuse.The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients.HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified.The American and European guidelines recommended implementation of surveillance programs with ultrasound every six months in patient atrisk for developing HCC.The diagnosis of HCC can be based on non-invasive criteria(only in cirrhotic patient)or pathology.Accurately staging patients is essential to oncology practice.The ideal tumour staging system in HCC needs to account for both tumour characteristics and liver function.Treatment allocation is based on several factors:Liver function,size and number of tumours,macrovascular invasion or extrahepatic spread.The recommendations in terms of selection for different treatment strategies must be based on evidence-based data.Resection,liver transplant and interventional radiology treatment are mainstays of HCC therapy and achieve the best outcomes in well-selected candidates.Chemoembolization is the most widely used treatment for unresectable HCC or progression after curative treatment.Finally,in patients with advanced HCC with preserved liver function,sorafenib is the only approved systemic drug that has demonstrated a survival benefit and is the standard of care in this group of patients.

    For patients with unresectable pancreatic carcinoma, a few kind of treatment including chemoradiation, intraoperative radiation and intra-arterial chemotherapy was done. Chemoradiation using 5FU, CDDP, ADM and radiation to the lesion and liver was performed in 16 patients, showing a response rate of 10%. One-year survivals rate and mean a survival period of this group was 11.7% and 6.6 months respectively. Postmortem autopsy in 6 cases revealed insufficient therapeutic effects in both primary and metastatic site. Because of above-mentioned reasons, chemoradiation therapy to the pancreatic carcinoma, which we did, was estimated as ineffective. (author)

    2011-12-01

    Full Text Available Gastric carcinoma is frequently diagnosed with an advanced stage of non-curable tumor growth characterized by infiltration of the gastric serosa, peritoneal tumor spread and/or metastases within lymph nodes and liver. Currently, there is a controversy on the value of palliative resection with regard to the safety and benefit to the patient outcome. Based on the available literature, this overview summarizes the various aspects and interprets the limited data on the palliative resection of gastric carcinoma. It turns out that the available study results may indicate potential for an improved quality of life and a prolongation of survival if an acceptable morbidity and mortality are present.

    Full Text Available Michael C Kew Department of Medicine, Groote Schuur Hospital and University of Cape Town, Cape Town, South Africa Abstract: Hepatocellular carcinoma is one of the major malignant tumors in the world today. The number of new cases of the tumor increases year by year, and hepatocellular carcinoma almost always runs a fulminant course and carries an especially grave prognosis. It has a low resectability rate and a high recurrence rate after surgical intervention, and responds poorly to anticancer drugs and radiotherapy. Hepatocellular carcinoma does not have a uniform geographical distribution: rather, very high incidences occur in Eastern and Southeastern Asia and in sub-Saharan Black Africans. In these regions and populations, the tumor shows a distinct shift in age distribution toward the younger ages, seen to greatest extent in sub-Saharan Black Africans. In all populations, males are more commonly affected. The most common risk factors for hepatocellular carcinoma in resource-poor populations with a high incidence of the tumor are chronic hepatitis B virus infection and dietary exposure to the fungal hepatocarcinogen aflatoxin B1. These two causative agents act either singly or synergistically. Both the viral infection and exposure to the fungus occur from early childhood, and the tumor typically presents at an early age. Chronic hepatitis C virus infection is an important cause of hepatocellular carcinoma in resource-rich countries with a low incidence of the tumor. The infection is acquired in adulthood and hepatocellular carcinoma occurs later than it does with hepatitis B virus-induced tumors. In recent years, obesity and the metabolic syndrome have increased markedly in incidence and importance as a cause of hepatocellular carcinoma in some resource-rich regions. Chronic alcohol abuse remains an important risk factor for malignant transformation of hepatocytes, frequently in association with alcohol-induced cirrhosis. Excessive iron

    Ovarian tumors have a low incidence in childhood, accounting for 1% of malignancies within the ages of 0-17 years. Small cell carcinoma of the ovary is a rare histology and historically has a poor prognosis. We report a case of an 11-year-old female diagnosed with small cell carcinoma of the ovary and hypercalcemia (SCCOHT). There was a strong family history of the disease, a reduction in the age of onset in the proband, and the absence of BRCA mutations. This case suggests the phenomenon of genetic anticipation in an ovarian cancer.

    2017-01-01

    Paraneoplastic neurological disorder (PND) is a condition due to immune cross-reactivity between the tumour cells and the normal tissue, whereby the “onconeural” antibodies attack the normal host nervous system. It can present within weeks to months before or after the diagnosis of malignancies. Nasopharyngeal carcinoma is associated with paraneoplastic syndrome, for example, dermatomyositis, and rarely with a neurological disorder. We report on a case of nasopharyngeal carcinoma with probable PND. Otolaryngologists, oncologists and neurologists need to be aware of this condition in order to make an accurate diagnosis and to provide prompt treatment. PMID:28381934

    Full Text Available Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone. Metastases involving oral and maxillofacial region are extremely rare. We described a case of malar metastasis revealing a follicular variant of papillary thyroid carcinoma, presenting with pain and swelling of the left cheek in a 67-years-old female patient with an unspecified histological left lobo-isthmectomy medical history. To our knowledge, this is the first recorded instance of a malar metastasis from a follicular variant of papillary thyroid carcinoma.

    2009-11-01

    Ovarian serous papillary carcinoma, although rarely metastasizing to the breast, is often challenging based on morphology alone, particularly from the micropapillary variant of breast carcinoma. Gross cystic disease fluid protein-15, although a specific marker, can be negative in up to 50% of breast carcinomas. Wilm's tumor gene 1 (WT-1) has been identified as a useful marker to differentiate metastatic ovarian serous papillary carcinoma from primary breast carcinoma; however, it has recently been shown in the micropapillary variant of the primary breast carcinoma making it a less specific marker. PAX 2, a nuclear transcription factor, was recently observed in ovarian serous papillary carcinomas. In this study of 89 breast carcinoma cases, 26 micropapillary carcinoma, and 63 nonmicropapillary carcinoma types were retrieved from our pathology archives, represented on a single tissue microarray (TMA) with a 3-fold redundancy (TMA-1, TMA-2). In addition, whole tissue sections of a variety of benign and neoplastic müllerian tissues were surveyed with the PAX 2 immunostain. All cases were stained with rabbit polyclonal PAX 2 antibody and, in addition, the 5 metastatic ovarian serous carcinoma cases were stained with WT-1 as well for comparison. Only nuclear staining was considered positive. All primary breast carcinomas represented on TMA-1 and TMA-2 were entirely negative for PAX 2 100% (89/89), whereas 100% (5/5) of all metastatic ovarian serous carcinomas showed moderate-to-strong staining. PAX 2 expression was comparable with WT-1 as well in the metastatic ovarian serous carcinoma group. We therefore conclude that PAX 2 is a promising new, sensitive, and specific müllerian immunomarker for ovarian serous carcinomas (primary and metastatic).

    The cDNA microarrays allows the classification of breast cancers into 6 groups: luminal A, luminal B, luminal C, normal breast-like, human epidermal growth factor receptor 2-positive, and basal-like. This latter is characterized by the expression of basal cytokeratins (CKs), and frequent negativity for hormone receptors and human epidermal growth factor receptor 2. There is a marked parallelism between triple negative breast carcinomas and basal-like carcinoma, but these are not equivalent terms. Estimated concordance is around 80%. CK5 seems to be the best marker for the identification of these tumors. Other good markers to identify these tumors are CK14, CK17, and epidermal growth factor receptor. A subset of triple negative breast carcinomas has myoepithelial differentiation, with positivities for smooth muscle actin, p63, S-100, and CD10 among others. Recent studies suggest that basal like carcinomas are originated from mammary stem cells.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    2013-11-01

    Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that has morphologic features similar to secretory carcinoma of the breast and that also harbors the same ETV6 translocation. Diffuse mammaglobin and S-100 immunoreactivity are used to differentiate MASC from its morphologic mimics, especially acinic cell carcinoma and adenocarcinoma, not otherwise specified. However, the combination of mammaglobin and S-100 immunoreactivity has not been well studied in other types of salivary gland carcinomas that may have focal areas reminiscent of MASC. Here we evaluated mammaglobin and S-100 immunoreactivity in 15 cases each of polymorphous low-grade adenocarcinoma, adenoid cystic carcinoma and mucoepidermoid carcinoma, and also in 2 cases of adenocarcinoma, not otherwise specified, and 1 mucinous adenocarcinoma. Cases with significant co-expression of mammaglobin and S-100 (moderate or strong immunoreactivity in >25% of tumor cells) were further analyzed by fluorescence in situ hybridization using the ETV6 (12p13) break-apart probe. Nine cases (60%) of polymorphous low-grade adenocarcinoma and two (13.3%) of adenoid cystic carcinoma met the criteria for significant co-expression of mammaglobin and S-100. All were negative for the ETV6 translocation by fluorescence in situ hybridization. Although mammaglobin and S-100 positivity was seen in the majority of polymorphous low-grade adenocarcinomas and a minority of adenoid cystic carcinomas, none were positive for the ETV6 translocation characteristic of MASC. This indicates a need for caution in the use of immunohistochemistry for diagnosing MASC, especially in the absence of cytogenetic confirmation.

    Uterine papillary serous carcinoma (UPSC) is a clinically aggressive and morphologically distinctive variant of endometrial carcinoma that has been recognized recently as a distinct entity. The association between radiation therapy (RT) and UPSC is rarely described in the literature. We describe the clinicopathologic features of a 71-year-old patient with UPSC that developed 15 years after radiation therapy for squamous cell carcinoma of cervix, stage IIB. In the subtotal hysterectomy specimen the endometrium was irregular with multifocally raised masses. Microscopically, the tumor was composed of high-grade papillary serous carcinoma focally admixed with solid transitional cell carcinomatous areas and multifocal intraepithelial carcinoma in adjacent atrophic endometrium. The tumor exhibited diffuse infiltrative growth with frequent lymphatic tumor emboli in the myometrium. Immunohistochemical staining for p53 and c-erbB-2 were positive in about 70% of the tumor cells. Carcinoembryonic antigen (CEA) was focally positive. Ki-67 positive cells were present in about 60% of the tumor cells. The tumor directly extended to the cervix and perirectal soft tissue and metastasized to the omentum. Intraoperative pelvic washing cytology was positive for papillary adenocarinoma cells. The possible etiologic role of radiation is discussed, and the literature on endometrial carcinomas developing after RT is reviewed.

    Introduction Malignant sinonasal tumors comprise less than 1% of all neoplasms. A wide variety of tumors occurring primarily in this site can present with an undifferentiated or poorly differentiated morphology. Among them are esthesioneuroblastomas, sinonasal undifferentiated carcinomas, and neuroendocrine carcinomas. Objectives We will discuss diagnostic strategies, recent advances in immunohistochemistry and molecular diagnosis, and treatment strategies. Data Synthesis These lesions are diagnostically challenging, and up to 30% of sinonasal malignancies referred to the University of Texas MD Anderson Cancer Center are given a different diagnosis on review of pathology. Correct classification is vital, as these tumors are significantly different in biological behavior and response to treatment. The past decade has witnessed advances in diagnosis and therapeutic modalities leading to improvements in survival. However, the optimal treatment for esthesioneuroblastoma, sinonasal undifferentiated carcinoma, and neuroendocrine carcinoma remain debated. We discuss advances in immunohistochemistry and molecular diagnosis, diagnostic strategies, and treatment selection. Conclusions There are significant differences in prognosis and treatment for esthesioneuroblastoma, neuroendocrine carcinoma, and sinonasal undifferentiated carcinoma. Recent advances have the potential to improve oncologic outcomes but further investigation in needed. PMID:25992139

    We evaluated results of the treatment for invasive ductal pancreatic carcinoma, which accounted for 90.6% of all pancreatic carcinomas. Three hundred thirty-six patients with this carcinoma (214 men and 122 women) were divided into two groups: one was admitted between 1978 and 1987, and the other, between 1988 and 1997. Investigation items were as follows: survival period (median), one-year survival rate, stage, diabetes, treatment. The latter group (193 cases in 1988-1997) lived slightly but significantly longer than the former group (143 cases in 1978-1987): median survival 125{yields}161.5 days, one-year survival rate 13.3{yields}18.7%. As a cause of the improvement, we obtained results that suggested the usefulness of radiotherapy: trialed cases of radiotherapy 44.0{yields}50.2%, median survival 146{yields}199.5 days, and one-year survival rate 9.5{yields}14.6%. In conclusion, results of the treatment for pancreatic carcinoma showed a slight but significant improvement. (author)

    We studied two autopsy cases of primary pituitary carcinoma. Case-1. A 45 year old female was admitted on Oct. 4 1978, with a complaint of right homonymous hemianopsia. And diagnosis was pituitary adenoma. Partial removal of pituitary tumor was performed on Oct. 23 1978. She died on Dec. 5 1978 due to bleeding of gastrointestinal tract. Autopsy disclosed a pituitary carcinoma invading the left hypothalamus, mamillary body, optic and V cranial nerves, and mid brain as well as sphenoid bone. No extracranial metastasis was noted. Case-2. A 44 year old female with a history of acromegaly for 6 years was admitted with a complaint of headache on May 8 1976. She was diagnosed as having pituitary adenoma. The subtotal removal of pituitary tumor was performed on May 21 1976 and followed by 4500 rad irradiation. At this time, pathological diagnosis was eosinophilic adenoma. Seven years later, she complained of progressive right hearing disturbance, dysarthria and ataxic gait 1983. The second subtotal removal of pituitary tumor was performed with a diagnosis of recurrence of pituitary adenoma on Oct. 7 1983. After the operation, she complicated sepsis and died on Jan. 14 1984. An autopsy disclosed a pituitary carcinoma from residual pituitary gland, continuously extending to the subarachnoid space of the pons, and invading right cerebello-pontine angle and cerebellum. The histological examination revealed pituitary carcinoma with high pleomorphism and glioblastoma multiform-like feature were within the tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

    OBJECTIVE To determine the ideal method of surgical preoperative treatment for perforation with esophageal carcinoma.METHODS 36 cases of perforation with esophageal carcinoma were treated surgically in this series.Perforations occurred into the right lung in14 cases ,the mediastinum in 17 cases and trachea in 5 cases.Open thoracic surgery was performed in 34 cases,in which the right thoracic approach using a 3-incision method was applied in 16 cases,and operation by stages in 15 cases.Of the 34 cases,retrosternal substitution of the esophagus with stomach or colon was performed in 26 cases.RESULTS Surgery was successful in 31 cases and operative death occurred in 3 cases.The postoperative follow up study was from 3~72months.Of these cases 15 wree alive at 7~12 months, 2 at 24 months,and 1 at 72 months. The results can be considered satisfactory.CONCLUSION The therapeutic results of surgical treatment of perforation with esophageal carcinoma were markedly superior to that of conventional conservative treatment. The authors suggest that surgical intervention without delay should be undertaken for patients having a perforation with carcinoma of the esophagus. A right thoracic approach with a 3-incision method (retrosternal replacement of esophagus with stomach or colon) or operation by stages is preferable.

    The survival of patients with superior sulcus lung carcinoma and the effects of treatment were reviewed. From a prospective database of 4123 consecutive new patients with lung carcinoma, 131 (3.2%) cases of superior sulcus lung carcinoma were identified. Seventy-four patients were planned to receive radiation with palliative intent, 53 radical radiotherapy and one was observed only. The remaining three patients, with small-cell carcinoma, were treated with chemotherapy with or without radiotherapy. Of the 53 radically treated patients, nine were treated with pre-operative radiation prior to intended radical resection. Analysis was carried out on the effect on survival of performance status, nodal involvement, weight loss, vertebral body or rib involvement, treatment intent and radical combined modality treatment compared with radical radiation alone. The estimated median survival for the whole group was 7.6 months; for those treated radically it was 18.3 months, while for the palliatively treated patients it was 3.7 months. Radically treated patients with no initial nodal involvement had an estimated median survival of 22 months, while radically treated patients with nodal involvement had an estimated median survival of 8.4 months (P = 0.003). There were no statistically significant differences in survival between radically treated patients grouped according to initial weight loss, performance status, or vertebral body and rib involvement. Patients treated with pre-operative radiation did not survive significantly longer than patients treated with radiation alone, although the numbers are small. 33 refs., 2 tabs., 4 figs.

    The cholangio carcinoma of extrahepatic bile duct is one of the common cause of obstructive jaundice, and the sonography is now the most convenient initial examination of theses cases. The location of 25 proven cases of extrahepatic cholangio carcinoma were classified as Klatskin type(6 cases), common hepatic duct(CHD)(9 cases) and common bilduct(CBD)(10cases). And the sonographic findings were analysed. The characteristic sonographic finding of Klatskin tumor was tqpered narrowing of dilated intrahepatic ducts at portal hepatis without communication between both lobe bile ducts. The CHD, cancer showed communicating dilatation of the intrahepatic ducts, but CHD cancer showed ommunicating dilatation of the intrahepatic ducts, but there was no dilatation of gall bladder or CBD, and in case of CBD cancer, entire biliary trees were usually dilated. With the sonographic findings onle, 19 of 25 cases(76%)were diagnosed as cholangio carcinoma, and 13 of 25 cases (52%) were diagnosed correctly the involved site as well as the malignant nature. The sonographic accuracy of the extrahepatic cholangiocarcinoma was greater in Klatskin tumor than the CHD or CBD cancer. Sonogram is most valuable screening study for cholangio carcinoma, and the CT scan and direct cholangiography such as PTC or ERCP have compensatory roles in detecting hepatic metastasis, regional adenopathy and length of involved bile duct

  5. Temozolomide in aggressive pituitary adenomas and carcinomas

    Full Text Available Temozolomide is an alkylating agent used in the treatment of gliomas and, more recently, aggressive pituitary adenomas and carcinomas. Temozolomide methylates DNA and, thereby, has antitumor effects. O6-methylguanine-DNA methyltransferase, a DNA repair enzyme, removes the alkylating adducts that are induced by temozolomide, thereby counteracting its effects. A Medline search for all of the available publications regarding the use of temozolomide for the treatment of pituitary tumors was performed. To date, 46 cases of adenohypophysial tumors that were treated with temozolomide, including 30 adenomas and 16 carcinomas, have been reported. Eighteen of the 30 (60% adenomas and 11 of the 16 (69% carcinomas responded favorably to treatment. One patient with multiple endocrine neoplasia type 1 and an aggressive prolactin-producing adenoma was also treated and demonstrated a good response. No significant complications have been attributed to temozolomide therapy. Thus, temozolomide is an effective treatment for the majority of aggressive adenomas and carcinomas. Evidence indicates that there is an inverse correlation between levels of O6-methylguanine-DNA methyltransferase immunoexpression and therapeutic response. Alternatively, high-level O6-methylguanine-DNA methyltransferase immunoexpression correlates with an unfavorable response. Here, we review the use of temozolomide for treating pituitary neoplasms.

    Full Text Available Abstract Background Calcineurin (CaN is an important serine-threonine phosphatase (PP2B, which plays a crucial role in calcium-calmodulin mediated signal transduction events. Calcineurin has been implicated in pathogenesis of various diseases cardiac hypertrophy, diabetic neuropathy and Alzheimer's, however its role in neoplasia remains unclear. Results In view of this we evaluated the calcineurin activity in serum and biopsy samples collected from women diagnosed with invasive squamous cell carcinoma of cervix. A significant reduction was observed in the calcineurin activity in cancer cervix patients compared to the control group. However the calcineurin activity remained unaltered in the cervical scrapes obtained from patients diagnosed with low-grade squamous intra epithelial lesions (LSIL. Interestingly the downregulation of calcineurin activity in squamous cell carcinomas was not accompanied by any significant change in DNA-binding affinity of the transcriptional factor NFAT (Nuclear Factor of Activated T-cells. All the squamous cell carcinoma samples used in the present study were positive for high-risk human papillomavirus (HPV types. Conclusion The present study demonstrates the downregulation of calcineurin activity in squamous cell carcinoma of cervix with high risk HPV infection. We conclude that perturbations in calcineurin-mediated pathway may be involved in development of cervical neoplasia.

    We describe 2 adult women (72 and 54 years), 1 with a low-grade noninvasive papillary urothelial carcinoma of the renal pelvis, who 14 years later developed a papillary carcinoma in 1 thyroid lobe and a medullary carcinoma in the contralateral lobe. Both neoplasms were similar in size and appeared symmetrical. Despite its small size, the medullary carcinoma metastasized in multiple cervical lymph nodes. The second patient had a high-grade invasive papillary urothelial carcinoma of the renal pelvis that infiltrated the renal parenchyma and metastasized in one of the lungs. Five months later, a papillary carcinoma was discovered in the thyroid gland. The 2 papillary thyroid carcinomas were of the follicular variant. Adjacent to 1 papillary carcinoma, there was a dominant nodule of a colloid and adenomatous goiter. The medullary carcinoma contained stromal amyloid and was immunoreactive for calcitonin and carcinoembryonic antigen. There was no C-cell hyperplasia (medullary carcinoma in situ). The 2 patients are alive, 1 is living with pulmonary metastasis from the high-grade urothelial carcinoma. Twelve cases of this neoplastic association were registered in the Survey, Epidemiology, and End Results Program from 1980 to 2009. We believe that the combination of these unusual neoplasms in the same patient may represent a new sporadic neoplastic syndrome.

    Colorectal self-expandable metal stents (SEMS) have been used successfully as preoperative bridges to surgery for obstructive left-sided colorectal carcinoma. Endoscopic relief of the obstruction allows for full bowel preparation and accurate preoperative staging. A laparoscopic approach, considered by many to be contraindicated in the presence of obstruction, becomes feasible after endoscopic decompression. We present a case of obstructive carcinoma of the descending colon successfully treated with endoscopic decompression with colorectal SEMS. Subsequent staging with computed tomography revealed a renal cell carcinoma in the left kidney. Synchronous laparoscopic resection of the two carcinomas was performed, with no morbidity. To the best of our knowledge, this is the first report of endolaparoscopic left hemicolectomy and synchronous laparoscopic radical nephrectomy for obstructive carcinoma of the descending colon and renal cell carcinoma. The advantages of colorectal SEMS and the endolaparoscopic approach in managing obstructive colorectal carcinoma are discussed.

    Full Text Available Objective: The aim of this study was to investigate p53 and COX-2 expressions in basal cell carcinoma, squamous cell carcinoma and actinic keratoses, and to determine a possible relationship.Material and Method: 50 basal cell carcinoma, 45 squamous cell carcinoma and 45 actinic keratosis cases were evaluated. The type of tumor in basal cell carcinoma and tumor differentiation in squamous cell carcinoma were noted and the paraffin block that best represented the tumor was chosen. Immunostaining by p53 and COX-2 was performed on sections of the paraffin blocks.Results: p53 expression was observed in 98% of basal cell carcinoma, 88.9% of squamous cell carcinoma and all actinic keratosis cases. p53 expression was also noted in non-dysplastic appearing epithelium in actinic keratosis cases. COX-2 expression was seen in 90, 100 and 88.9% of the basal cell carcinoma, squamous cell carcinoma and actinic keratosis groups, respectively. Skin appendages, inflammatory cells and vascular structures were also stained by COX-2 besides tumor tissue. COX-2 expression increased by the p53 expression increase in basal cell carcinoma and squamous cell carcinoma. p53 and COX-2 expressions were not related in terms of tumor type in the BCC and were not related in terms of differentiation in SCC.Conclusion: The existence of p53 expression in actinic keratosis cases has supported the idea that p53 plays a role in the early steps of carcinogenesis in skin cancers. The fact that the expression of COX-2 increases in line with the increase of p53 expression in basal cell carcinoma and squamous cell carcinoma cases indicates that COX-2 expression may be affected by p53

    Full Text Available O carcinoma verrucoso é uma variante menos agressiva do carcinoma de pênis que raramente apresenta metástase linfonodal. Neste tipo de tumor, o tratamento cirúrgico constitui a principal forma de controle da doença. O objetivo do trabalho é relatar um caso de carcinoma verrucoso de pênis que foi submetido a tratamento operatório através de penectomia total em um paciente com 44 anos apresentando lesão ulcerada em região dorsal de pênis. Progrediu o quadro com infecção local e linfadenomegalia inguinal bilateral. Biópsia com diagnóstico de carcinoma verrucoso de pênis. Foi indicado penectomia para o paciente. Apesar de o carcinoma verrucoso ser menos invasivo, foi optado por penectomia total com implante da uretra no períneo. Isto se deu por conta da grande extensão do tumor que comprometia todo o órgão. Apesar de boa diferenciação do tumor, a realização de penectomia total foi necessária no caso em questão pelo grande acometimento da lesão. O esvaziamento ganglionar também não foi realizado e sua necessidade para esses casos não é comprovada. O tratamento com antibióticos é obrigatório e geralmente melhora a adenopatia regional como no caso acima descrito.

    2012-06-01

    The incidence of penile cancer varies from country to country, with the highest figures reported for countries in Africa, South America, and Asia and lowest in the United States and Europe. Causes of this variation are not clear, but they are thought to be related to human papillomavirus infection, smoking, lack of circumcision, chronic inflammation, and poor genital hygiene. Most penile tumors are squamous cell carcinomas, and a variegated spectrum of distinct morphologies is currently recognized. Each one of these subtypes has distinctive pathologic and clinical features. About half of penile carcinomas are usual squamous cell carcinomas, and the rest corresponds to verrucous, warty, basaloid, warty-basaloid, papillary, pseudohyperplastic, pseudoglandular, adenosquamous, sarcomatoid, and cuniculatum carcinomas. Previous studies have found a consistent association of tumor cell morphology and human papillomavirus presence in penile carcinomas. Those tumors composed of small- to intermediate-sized, basaloid ("blue") cells are often human papillomavirus positive, whereas human papillomavirus prevalence is lower in tumors showing large, keratinizing, maturing eosinophilic ("pink") cells. Human papillomavirus-related tumors affect younger patients, whereas human papillomavirus-unrelated tumors are seen in older patients with phimosis, lichen sclerosus, or squamous hyperplasia. This morphologic distinctiveness is also observed in penile intraepithelial neoplasia. The specific aim of this review is to provide a detailed discussion on the macroscopic and microscopic features of all major subtypes of penile cancer. We also discuss the role of pathologic features in the prognosis of penile cancer, the characteristics of penile precursor lesions, and the use of immunohistochemistry for the diagnosis of invasive and precursor lesions.

    CCL2 is a chemokine known to recruit monocytes/macrophages to sites of inflammation. CCL2 is also associated with tumor progression in several cancer types. Recently, we showed that the N-terminus of CCL2 is modified to a pyroglutamate (pE)-residue by both glutaminyl cyclases (QC (QPCT)) and its isoenzyme (isoQC (QPCTL)). The pE-residue increases stability against N-terminal degradation by aminopeptidases. Here, we report an upregulation of QPCT expression in tissues of patients with thyroid carcinomas compared with goiter tissues, whereas QPCTL was not regulated. In thyroid carcinoma cell lines, QPCT gene expression correlates with the mRNA levels of its substrate CCL2. Both QPCT and CCL2 are regulated in a NF-κB-dependent pathway shown by stimulation with TNFa and IL1b as well as by inhibition with the IKK2 inhibitor and RNAi of p50. In the culture supernatant of thyroid carcinoma cells, equal amounts of pECCL2 and total CCL2 were detected by two ELISAs discriminating between total CCL2 and pECCL2, concluding that all CCL2 is secreted as pECCL2. Activation of the CCL2/CCR2 pathway by recombinant CCL2 increased tumor cell migration of FTC238 cells in scratch assays as well as thyroid carcinoma cell-derived CCL2-induced migration of monocytic THP1 cells. Suppression of CCL2 signaling by CCR2 antagonist, IKK2 inhibitor, and QPCT RNAi reduced FTC238 cell growth measured by WST8 proliferation assays. Our results reveal new evidence for a novel role of QC in thyroid carcinomas and provide an intriguing rationale for the use of QC inhibitors as a means of blocking pECCL2 formation and preventing thyroid cancer metastasis.

    We wanted to evaluate the degree of conformity of papillary carcinoma and follicular carcinoma to the reported ultrasonographic findings of malignant thyroid tumor. Between January 2003 and December 2004, fine needle aspiration biopsy was performed in 1,036 patients with palpable and nonpalpable thyroid lesions. We retrospectively reviewed the ultrasonographic findings of patients with papillary carcinomas (n = 127) and follicular carcinomas (n 23) that were proven by operation or fine needle aspiration biopsy. We analyzed the ultrasonographic findings of these nodules based on the reported ultrasonographic findings of malignant thyroid tumor: hypoechogenicity, a taller than wide orientation, a microlobulated or irregular margin, a thick hypoechoic rim (halo sign), microcalcification and cystic change. The echogenicity was hypoechoic in 72.4% (92/127) of the papillary carcinomas, but it was isoechoic in 65.2% (15/23) of the follicular carcinomas (p < 0.001). The nodule shape was tall or round in 74.1% of the papillary carcinomas, but it was flat in 72.7% of the follicular carcinomas (p < 0.001). The tumor margin was microlobulated or irregular in 92.9% of the papillary carcinomas and in 60.9% of the follicular carcinomas (p < 0.001). A hypoechoic rim was seen in 26% of the papillary carcinomas (thin rim: 13.4%, thick rim: 12.6%) and in 86.6% of the follicular carcinomas (thin rim: 39.1%, thick rim: 47.8%, p < 0.001). Microcalcifications were demonstrated in 33.9% of the papillary carcinomas and in none of the cases of follicular carcinoma (p < 0.001). A solid mass without cystic change were seen in 98.4% of the papillary carcinomas and in 82.6% of the follicular carcinomas (p < 0.001). The previously reported ultrasonography findings of malignant thyroid tumor are in conformity with most of the papillary carcinomas, but not with follicular carcinomas. The current ultrasonographic features for thyroid malignancy should be cautiously applied as the indication for

    Primary anaplastic carcinoma is a rare variant of small intestinal cancer. Most reports of primary anaplastic carcinoma of the small intestine are isolated case reports, therefore the clinicopathological features, therapeutic management, and surgical outcome of this tumor type remain unclear. This review analyzes the available clinical characteristics of primary anaplastic carcinoma of the small intestine and investigates key differences from differentiated adenocarcinoma of the small intestine. A Medline search was performed using the keywords 'small intestine' and 'anaplastic carcinoma' or 'undifferentiated carcinoma'. Additional articles were obtained from references with in the papers identified by the Medline search. The literature revealed a poor prognosis for patients who underwent surgical resection for anaplastic carcinoma of the small intestine, which gave a 3-year overall survival rate of 10.8% and a median survival time of 5.0 mo. The literature suggests that anaplastic carcinoma is markedly more aggressive than differentiated adenocarcinoma of the small intestine. Surgical resection with the aim of complete tumor removal provides the only beneficial therapeutic option for patients with anaplastic carcinoma of the small intestine, because chemotherapy and radiation therapy have no significant effect on the rate of survival. However, despite complete tumor resection, most patients with anaplastic carcinoma of the small intestine are at great risk of disease recurrence. Multicenter clinical trials are expected to provide additional therapeutic strategies and establish the efficacy of multimodality adjuvant therapy. This report also highlights the importance of a systematic diagnostic approach for anaplastic carcinoma of the small intestine.

    Objective: To analyze the relationship of Stat3 expression with clinical stages, tissue types, p53and proliferation cell nuclear antigen (PCNA) in human lung carcinoma, and to evaluate the role of Stat3 in the pathogenesis of lung carcinoma. Methods: Immunohistochemical method were used to detected Stat3,p53 and PCNA in different tissues of patients (n= 42) with lung carcinoma who accepted neither radiotherapy nor chemotherapy. Results: The positive rate of Stat3 was 81.0% in lung carcinoma and its expression level was related to the tissue type but not to T, N or the clinical stage. The expression level of Stat3 in non-small cell lung carcinoma (NSCLC) was higher than that in small cell lung carcinoma (SCLC). A positive correlation of the expression of Stat3 with that of p53 and PCNA was identified. Conclusion: The expression level of Stat3 is abnormal in lung carcinoma. Stat3 may be involved in the regulation of p53 gene in lung carcinoma cell, it may accelerate the proliferation of lung carcinoma cells and play an important role in the pathogenesis of lung carcinoma.

    This study examined the biological and clinical significance of NAC1 (nucleus accumbens associated 1) expression in both cervical squamous cell carcinomas and adenocarcinomas/adenosquamous carcinomas. Using immunohistochemistry, the frequency of positive NAC1 expression in adenocarcinomas/adenosquamous carcinomas (31.0%; 18/58) was significantly higher than that in squamous cell carcinomas (16.2%; 12/74) (P = .043). NAC1 gene amplification was identified by fluorescence in situ hybridization in 5 (7.2%) of 69 squamous cell carcinomas. NAC1 amplification was not identified in the adenocarcinomas (0%; 0/58). Positive NAC1 expression was significantly correlated with shorter overall survival in squamous cell carcinomas (P NAC1 expression in squamous cell carcinomas was an independent prognostic factor for overall survival after standard radiotherapy (P = .0003). In contrast to squamous cell carcinomas, positive NAC1 expression did not correlate with shorter overall survival in adenocarcinomas/adenosquamous carcinomas (P = .317). Profound growth inhibition, increased apoptosis, decreased cell proliferation, and decreased cell migration and invasion were observed in silencing RNA-treated cancer cells with NAC1 overexpression compared with cancer cells without NAC1 expression. NAC1 overexpression stimulated proliferation, migration, and invasion in the cervical cancer cell lines TCS and Hela P3, which normally lack NAC1 expression. These findings indicate that NAC1 overexpression is critical to the growth and survival of cervical carcinomas irrespective of histologic type. Furthermore, they suggest that NAC1 silencing RNA-induced phenotypes depend on the expression status of the targeted cell line. Therefore, cervical carcinoma patients with NAC1 expression may benefit from a targeted therapy irrespective of histologic type.

  3. A subset of prostatic basal cell carcinomas harbor the MYB rearrangement of adenoid cystic carcinoma.

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

    Basaloid squamous cell carcinoma of the esophagus is a rare variant of squamous cell carcinoma. We reviewed 878 cases of esophageal squamous cell carcinoma and detected 22 cases (3%) of basaloid squamous cell carcinoma. These tumors and stage-matched paired conventional squamous cell carcinomas were investigated for clinicopathologic features and immunoreactivity of cytokeratin subtypes, p53, B-cell lymphoma 2 (bcl-2), β-catenin, and epidermal growth factor receptor. Molecular aberrations in p53, CTNNB1 (the gene encoding β-catenin), and epidermal growth factor receptor (EGFR) were also determined. Patients with basaloid squamous cell carcinomas demonstrated a 5-year survival rate of 42%, significantly worse than those with well-differentiated squamous cell carcinoma (Pcarcinomas, the basaloid squamous cell carcinomas were less immunoreactive for cytokeratin 14, cytokeratin 903, and membranous β-catenin (Pcarcinomas, low-level expression of cytokeratin 14/cytokeratin 903 and mutations of p53 and EGFR had a significant influence on worse survival (Pcarcinoma, a neoplasm with particularly aggressive biologic behavior, should be differentiated from conventional squamous cell carcinomas. In this context, immunohistochemical assessment of several markers might provide a useful adjunct diagnostic tool. Aberrations of p53 and epidermal growth factor receptor genes are possibly involved in progression of esophageal basaloid squamous cell carcinoma.

    The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    Full Text Available Backround. Thyroglossal duct cyst (TDC is a developmental abnormality of the thyroid gland. Due to embryological remnants of thyroid tissue located in the TDC, the same malignant tumors that develop in the thyroid gland can also develop in the TDC. Methods. We present the unique case of a 39-year-old female with simultaneous de novo papillary carcinoma in a TDC and the thyroid gland. Results. With the suspicion of simultaneous papillary carcinoma in the TDC and the thyroid gland, Sistrunk procedure with total thyroidectomy and central neck exploration was performed. Conclusion. The clinician should have a high index of suspicion upon encountering papillary carcinoma of the TDC to differentiate de novo papillary carcinoma in the TDC from those originating from the thyroid gland, because papillary carcinoma in TDC may originate from an occult thyroid papillary carcinoma.

  4. Warthin-like papillary thyroid carcinoma: a case report

    Directory of Open Access Journals (Sweden)

    Haeri H

    2013-02-01

    Full Text Available Background: Warthin tumor- like papillary carcinoma of thyroid is a rare variant of papillary thyroid carcinoma. It is characterized by distinct papillary structures lined by oncocytic tumor cells with nuclear features of papillary carcinoma and marked lymphoplasmocytic infiltrate in the papillary stalks. This tumor derives its name from its resemblance to Warthin tumor of major salivary glands.Case presentation: We report a 54- year- old man presented with bilateral thyroid masses. Histopathological study showed papillary structures lined by cells with eosinophilic granular cytoplasm and ground- glass nuclei with lymphoplasmacytic infiltration of the stalks.Conclusion: Warthin tumor-like papillary thyroid carcinoma could be mistaken for benign lymphoepithelial lesions such as Hashimoto thyroiditis, Hurthle cell tumors and tall cell variant of papillary carcinoma. Follow- up information on the previously reported cases has suggested that these tumors behave similarly to usual papillary carcinoma.

  5. Mandibular Destruction Secondary to Invasion by Carcinoma Cuniculatum.

    Science.gov (United States)

    Shapiro, Michael C; Wong, Brian; O'Brien, Michael J; Salama, Andrew

    2015-12-01

    Carcinoma cuniculatum is a rare form of well-differentiated squamous cell carcinoma that is often misdiagnosed. It has a propensity for local invasion and rarely metastasizes. Oral carcinoma cuniculatum is exceedingly rare, with very few reported cases in the English-language literature. Classically, its presentation mimics osteomyelitis or a dental abscess, resulting in misdiagnosis, multiple biopsy examinations, and procedures before a final diagnosis of carcinoma cuniculatum. This case report describes the case of a 71-year-old woman who was referred to the authors' clinic for evaluation of persistent pain and swelling of the mandible. Multiple biopsy examinations were negative for malignancy, and the patient was misdiagnosed with osteomyelitis and dental abscess before obtaining an accurate diagnosis of carcinoma cuniculatum. The aim of this report is to provide a thorough clinical and histopathologic report of carcinoma cuniculatum of the mandible, provide a brief review of the literature, and highlight the difficulties in arriving at this uncommon diagnosis.

  6. Developments in the pathology of penile squamous cell carcinomas.

    Science.gov (United States)

    Chaux, Alcides; Velazquez, Elsa F; Algaba, Ferran; Ayala, Gustavo; Cubilla, Antonio L

    2010-08-01

    Most penile cancers are squamous cell carcinoma (SCC) originating in the epithelium covering glans, coronal sulcus, and foreskin. Several histologic subtypes have been described, each with distinctive clinicopathologic and outcome features. The most common subtype is the usual SCC, representing one half to two thirds of penile carcinomas. Penile verruciform tumors encompass verrucous, warty (condylomatous), and papillary, not otherwise specified, carcinomas. As a group, verruciform tumors are low grade, with low metastatic and mortality rates. In contrast, basaloid and sarcomatoid carcinomas are among the most aggressive penile tumors. Other SCC variants, such as carcinoma cuniculatum and pseudohyperplastic, adenosquamous and acantholytic carcinomas, are rare. The most relevant clinicopathologic and outcome features are outlined for each of these SCC subtypes, and an algorithm that might aid the pathologist in the histologic classification is presented. In addition, recommendations for handling penile cancer specimens, frozen section specimens, and pathology reports are provided.

  7. Thyroglossal duct cyst carcinoma with concurrent thyroid carcinoma: a case report

    Directory of Open Access Journals (Sweden)

    2008-04-01

    Full Text Available Abstract Introduction Thyroglossal duct carcinoma is a very rare finding and its presentation is similar to that of a benign cyst, which is a relatively common developmental abnormality that may manifest as a midline, neck mass. In general the diagnosis of thyroglossal duct carcinoma is based on the pathologic examination of the mass, but needle aspiration cytology, ultrasound and computed tomography play a role in the differential diagnosis of malignancy. Case presentation A further case of thyroglossal duct carcinoma and concurrent thyroid carcinoma with locoregional lymph node metastases affecting a 40-year-old woman followed up for 4 years is presented and discussed. Conclusion Sistrunk's surgical technique must always be the initial treatment, but in case of carcinoma further surgery, that is, thyroidectomy with or without lymph node dissection, and treatment with radioactive iodine have to be considered according to the microscopic and clinical findings. Accurate pre-operative clinical and radiological evaluation should be performed in order to plan surgical strategy.

    Epithelial-myoepithelial carcinoma is a rare salivary gland tumor. It comprises less than 1% of all salivary gland tumors. It generally arises from the parotid gland. Unusual sites of occurrence include sinonasal tract, lung, trachea, lacrimal gland and breast. Histopathologically epithelial-myoepithelial carcinoma comprises a dual population of ductal and myoepithelial cells. We report an extremely rare case of epithelial-myoepithelial carcinoma occurring in the sinonasal tract of young man.

    Science.gov (United States)

    Mellett, S; Verganti, S; Murphy, S; Bowlt, K

    2015-03-01

    Anal sac squamous cell carcinoma is rare in dogs. Five cases have been previously reported, treatment of which involved surgery alone. This report describes three further cases of canine anal sac squamous cell carcinoma which underwent medical (meloxicam) management alone, resulting in survival of up to seven months. No metastases were identified. Squamous cell carcinoma, although extremely uncommon, should be considered as a possible differential diagnosis when a dog is presented for investigation of an anal sac mass.

    Less than 10% of patients with anaplastic thyroid carcinoma survive 5 years when treated by operation and conventional irradiation, but survivors who are disease-free at 2 years appear to be cured. The administration of a small number of large radiation fractions (350 to 800 rads) failed to eradicate the local disease in 14 patients, all of whom died within 9 months. Hyperfractionation (100 rads qid at 3-hour intervals) caused complete tumour regression of 6 of 14 patients and partial regression in 7 others; the 1 patient whose tumour failed to respond was treated only once daily. However, the cost was high: two patients died of spinal cord necrosis and a third of pneumonitis due to the unexpected increase in radiation toxicity caused by the concurrent administration of Adriamycin. If an effective systemic treatment can be devised for this disease, hyperfractionation may be capable of eradicating the massive local tumour masses so characteristic of anaplastic thyroid carcinoma.

    Purpose To evaluate the potential of targeted photoacoustic imaging as a non-invasive method for detection of follicular thyroid carcinoma. Experimental Design We determined the presence and activity of two members of matrix metalloproteinase family (MMP), MMP-2 and MMP-9, suggested as biomarkers...... for malignant thyroid lesions, in FTC133 thyroid tumors subcutaneously implanted in nude mice. The imaging agent used to visualize tumors was MMP activatable photoacoustic probe, Alexa750-CXeeeeXPLGLAGrrrrrXK-BHQ3. Cleavage of the MMP activatable agent was imaged after intratumoral and intravenous injections...... With the combination of high spatial resolution and signal specificity, targeted photoacoustic imaging holds great promise as a noninvasive method for early diagnosis of follicular thyroid carcinomas....

  1. Complications of surgical treatment of cervical carcinoma

    1997-01-01

    Full Text Available A total of 302 patients with stage Ib and IIa cervical carcinoma were submitted to radical hysterectomy and lymphadenectomy during the period from 1980 to 1994. The morbidity rate was 37.5% and the mortality rate 0.6%. The most common intraoperative complications were injuries to the great pelvic vessels and the most frequent postoperative complications involved the urinary tract. The leading causes of morbidity were urinary infection (20.8%, bladder dysfunction (9.2% and ureteral fistulas (2.9%. Although the rate of complications was high, morbidity has been decreasing over the last five years. Thus, radical hysterectomy continues to be one of the methods for the treatment of early cervical carcinoma that presents an acceptable 5-year survival rate.

    2016-03-01

    Hepatocellular carcinoma (HCC) is an important cause of increasing mortality in elderly hemophilia population. Majority of the patients treated with virus non-inactivated factor concentrates prepared from large plasma pools prior to 1985 have been found to be infected with hepatitis C virus (HCV), a major risk factor for HCC. A PubMed search of articles published until February 2015 was performed utilizing the keywords hemophilia, malignancy, neoplasm, cancer, mortality, ageing hemophilia, epidemiology, hepatocellular carcinoma and liver cancer and the relevant articles were included. Contradictory reports are available in literature on the incidence of cancers in general in hemophilia population. Almost all the studies where the incidence of HCC or mortality due to HCC have been analyzed in hemophilia population show that a vast majority of these patients are HCV infected. The incidence of HCC though higher in hemophilic population is related to the higher incidence of HCV infection and not due to the hemophilia phenotype.

    Carcinoma cuniculatum (CC) is a rare, distinct clinico-pathological variant of squamous cell carcinoma (SCC) that is defined histologically by the characteristic infiltrative pattern of a deep, broad, and complex proliferation of stratified squamous epithelium with keratin cores and keratin-filled crypts. Herein, we present a case report of CC of the oral tongue and discuss its diagnosis, management, and outcome, as well as briefly review the world literature. To our knowledge, this is the first documented case of CC of the tongue to be reported in the English literature. We draw attention to its clinico-pathological features and highlight that awareness of this entity as a distinct variant of SCC facilitates its correct management.

    Necropsies were performed on 285 consecutively unclaimed Orang Asli bodies from Gombak Orang Asli Hospital during an eight-year period from May 1967 to April 1975. Of the 25 malignant neoplasms, hepatocellular carcinoma was by far the commonest (36%). The nine patients with this neoplasm had coexistant macronodular cirrhosis. There were 20 cases of cirrhosis; 45% of these had coexistant hepatocellular carcinoma. The 53,000 Orang Aslis living in West Malaysia comprise three tribes, the Negrito, Senoi, and Melayu Asli (Proto Malays). The Sinoi appear to have a high predilection for liver cancer, all our nine cases occurring in this group. These aboriginal people live in the jungles where they practice shifting cultivation and maintain their own dietary and social customs. Detailed studies of their dietary habits may provide a clue to the etiology of liver cancer in these people.

    Full Text Available Carcinoma gall bladder is a very aggressive disease with poor outcomes. Despite achievements in the field of advanced imaging techniques, there is a very high mortality rate of the disease Cancer is the second most common disease in India responsible for maximum mortality with about 0.3 million deaths per year. The magnitude of cancer problem in the Indian Sub-continent (sheer numbers is increasing due to poor to moderate living standards and inadequate medical facilities. Women are more commonly affected than men. The peak incidence occurs in people in their 60s, but the disease age range is from 29 to 90 years of age and there is great geographic and ethnic variation. Carcinoma gall bladder, a disease of old age, is now found in the younger age group and presents with greater ferocity.

    2014-09-01

    Full Text Available : Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by microscopic aggregation of activated macrophages which often develop epithelioid appearance and multinucleate giant cells. Granulomas are encountered in limited number of infectious and some non-infectious conditions. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin’s lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC is uncommon, with only few published reports in the literature. We describe a case of conventional (clear cell RCC associated with epithelioid cell granulomas within the tumor parenchyma.

  8. Radiotherapy for metastatic fibrolamellar hepatocellular carcinoma

    Directory of Open Access Journals (Sweden)

    Justin G. Peacock

    2013-07-01

    Full Text Available Fibrolamellar hepatocellular carcinoma (FLHCC is a rare variant of hepatocellular carcinoma (HCC that commonly affects young individuals without a prior history of liver disease. FLHCC commonly results in a better prognosis than HCC; however, the risk of recurrence and metastatic disease is high. FLHCC is typically treated by primary resection of the tumor with 50-75% cure rates. The use of radiation therapy in FLHCC has not been assessed on its own, and may show some success in a very few reported combination therapy cases. We report on the successful use of radiation therapy in a case of metastatic FLHCC to the lung following primary and secondary resections. Our treatment of the large, metastatic, pulmonary FLHCC tumor with 40 Gy in 10 fractions resulted in an 85.9% tumor volume decrease over six months. This suggests FLHCC may be a radiosensitive tumor and radiotherapy may be valuable in unresectable or metastatic tumors.

    2011-01-01

    Lung cancer is the leading cause of cancer death in men and women worldwide, with over a million deaths annually. Tobacco smoke is the major etiologic risk factor for lung cancer in current or previous smokers and has been strongly related to certain types of lung cancer, such as small cell lung carcinoma and squamous cell lung carcinoma. In recent years, there has been an increased incidence of lung adenocarcinoma. This change is strongly associated with changes in smoking behavior and cigarette design. Carcinogens present in tobacco products and their intermediate metabolites can activate multiple signaling pathways that contribute to lung cancer carcinogenesis. In this review, we summarize the smoking-activated signaling pathways involved in lung cancer.

    To evaluate the major prognostic factors in patients with pancreatic carcinoma.Methods : 113 cases of a particular disease were retrospectively analysed and 9 factors for prognosis were studied by muitivaritate analysis with Cox proportional hazards survival model. Survival rate was calculated by Kaplan-Meier estimation. Results:In this group,survival time was 0.1 to 82 months,and the median survival time was 3 months.Overall survival rates at month 6,12,18,36 were 35.6%, 20.3%, 15.9% and 6.2%, respectively.Multivariate analyses revealed significant prognostic factors as follows:jaundice, metastasis, therapy method and synthetic therapy. Conchusion: The prognosis of pancreatic carcinoma is determined by various factors. Jaundice and metastasis are independent predictors of poor survival.Radical operation and synthetic therapy will improve the prognosis.

    2014-11-01

    Full Text Available Secondary symptomatic gastrointestinal metastases from lung primary tumor are rare. They can cause a variety of clinical conditions such as perforation, obstruction and bleeding. Intestinal perforations of intestinal metastases have a very poor prognosis. We present a case of a patient with metastatic lung cancer who presents with intestinal perforation and pneumoperitoneum. A 67 year old male, immunosuppressed and smoker is diagnosed with acute abdomen secondary to perforation of a tumor of the terminal ileum, as well as three other similar injuries. Resection and anastomosis. The patient died two months after surgery. The final pathological diagnosis supports epidermoidide poorly differentiated lung carcinoma. It was concluded that given an intestinal perforation in a patient diagnosed with lung carcinoma, it shouldn´t be excluded the metastases origen . Surgery is a purely palliative procedure.

    Surgical treatment of esophageal cancer is largely palliative. To clarify the indication it is necessary to assess the effectiveness of the palliation in relief of dysphagia and the operative risks. In a retrospective study we analyzed the perioperative morbidity and follow-up in 25 patients with carcinoma of the esophagus treated between 1984 and 1988 (5 years). With combined anesthesia, early extubation and intensive pulmonary therapy, no perioperative respiratory insufficiency was observed. Perioperative mortality was 0%. An anastomotic leak in 2 patients with a cervical anastomosis was healed in both cases by conservative management. On hospital discharge all patients were able to eat normally. 13 patients died after 1 year on average (4 months to 3 years). 12 patients are alive 6 months to 4 years after operation, 10 of them without symptoms. Our results show that with optimal perioperative management of esophageal carcinoma low morbidity is possible and good palliation of dysphagia is feasible.

    Inflammatory breast carcinoma (IBC) diagnosis is usually based in the presence of typical clinical symptoms (redness and edema in more than 2/3 of the breast), which are not always associated with pathologic characteristics (subdermal lymphatics involvement). Whether exclusively pathologic findings without clinical symptoms are sufficient for IBC diagnosis remains controversial. A retrospective analysis of 163 clinically diagnosed IBC (CIC) either with dermal lymphatics invasion or not, was compared with another group of 99 patients with dermal lymphatics invasion without clinical symptoms (occult inflammatory carcinoma) (OIC). The following clinical and pathological characteristics have been analyzed and compared: age, menopausal status, clinical axillar node involvement, symptoms duration before diagnosis, grade, estrogen receptors, presence of metastases at diagnosis, local recurrence, metastasic dissemination, disease-free (DFS) and overall survival (OS). Median age was younger in CIC (52.3 vs. 63.8 years; p Prognosis of CIC patients is poorer, so this two entities should be clearly differentiated when therepeutic results are reported.

    2005-12-01

    A mass that developed in the lung of a 10-year-old mixed-breed dog was pathologically examined. Histopathological examination showed papillary and tubular growth of glandular epithelium-like cells in some areas and growth of squamous cells arranged in nests in other areas, showing coexistence of adenocarcinoma and squamous cell carcinoma in a lung tumour. Immunohistochemical staining with anti-keratin-cytokeratin antibody was strongly positive for cytoplasms in both components. Electron microscopically, the neoplastic cells of the adenocarcinoma component had features of glandular cells, with microvilli, numerous free ribosomes, large round secretory granules and intercellular desmosomes. Non-keratinized squamous cells had tonofilaments and intercellular desmosomes. These findings led to the diagnosis of primary adenosquamous carcinoma, which demonstrates phenotypic profiles characteristic of both epidermal keratinocytes and glandular epithelium.

    Hepatocellular carcinoma is a major health problem. It is the sixth most common cancer worldwide and the third most common cause of cancer-related death. Despite the availability of several treatment opportunities, diagnosis is still made in an advanced phase, limiting application of most therapeutic choices that currently are based on the Barcelona Clinic Cancer Liver Classification and include surgical resection, orthotopic liver transplantation and ablative methods for very early and early disease, arterial chemoembolization for intermediate stages and systemic therapy with sorafenib for advanced hepatocellular carcinoma. Thanks to novel advancements in knowledge of molecular pathogenesis of this tumor, many new systemic agents and locoregional treatments are in different stages of clinical development and they represent an important promise of further improvements in patients' survival.

    Skeletal metastasis in carcinoma cervix occurs in about 0.8-23% of cases. These lesions are usually radiographically lytic. Very few cases of metastases to the skull have been identiifed, about 5 cases to the best of our knowledge. We present a case of adenosquamous cell carcinoma of cervix with fat attenuating skull metastases in a 38-year-old lady that is not reported till date. The lesion was lytic, expansile and with negative attenuation of -15 to -30 Hounsifeld units corresponding to fat.Metastases must be included in the differentials of scalp lesions. A history of recent onset of swelling and associated lytic areas in calvarium on contrast enhanced computed tomography with multiplicity can give a clue to metastatic nature of disease.

    Squamous cell carcinoma of the penis is an uncommon cancer, though in one study it accounted for 90% of all penile cancers. Its association with balanitis xerotica obliterans (BXO) is a rare though recognized occurrence. We describe a case of a 46-year-old Caucasian male who first presented to our open-access clinic with a mild phimosis. An elective circumcision was performed and histological examination of the circumcision specimen showed BXO. He was lost to follow-up but re-presented three years later with a persistent tender penile ulcer which on biopsy showed no obvious sinister pathology. He returned a further two years later with a short history of bleeding from the ulcer, and another biopsy now confirmed penile squamous cell carcinoma. Our case emphasizes the importance of regular review of patients with BXO, in particular those with persistent symptoms.

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

In all cases the appearances closely resembled bronchial carcinoma. (orig.) With 5 figs., 21 refs.

  11. The Role of Anxiety in Prostate Carcinoma

    2010-01-01

    Although the impact of anxiety on patients with some types of cancer is well recognized, to the authors knowledge its impact on patients with prostate carcinoma has not been studied as thoroughly. The authors conducted a systematic review of the medical literature for high-quality articles that quantified anxiety levels in men with prostate carcinoma and identified 29 articles. Using the clinical timeline of prostate carcinoma to organize the articles, cross-sectional studies that reflected anxiety prevalence in populations and longitudinal studies that reflected changes in anxiety over time were identified. Anxiety appeared to fluctuate over the clinical timeline in response to stressors and uncertainty (such as at the time of screening and/or biopsy), rising before these times and falling afterward. Although anxiety levels in men age > 55 years who were at risk for prostate carcinoma were modest (10–15%), multiple studies found that these levels were substantially higher in men who presented for screening (> 50%), and “seeking peace of mind” was the motivation cited most frequently for pursuing screening. Most studies demonstrated a significant decrease in anxiety levels after a normal screening or biopsy result, although the proportion of men who remained anxious afterward did not fall to baseline levels (20–36%). Men who presented for prostate-specific antigen monitoring after treatment had elevated anxiety levels at the time of testing (23–33%). Many years after therapy for localized disease, anxiety levels were lower after prostatectomy (23%) compared with the levels after watchful waiting (31%). PMID:15959911

    Temozolomide is an alkylating agent used in the treatment of gliomas and, more recently, aggressive pituitary adenomas and carcinomas. Temozolomide methylates DNA and, thereby, has antitumor effects. O 6-methylguanine-DNA methyltransferase, a DNA repair enzyme, removes the alkylating adducts that are induced by temozolomide, thereby counteracting its effects. A Medline search for all of the available publications regarding the use of temozolomide for the treatment of pituitary tumors was perf...

    AIM To explore relationships between human carcinomas and mycoplasma infection.METHODS Monoclonal antibody PD4, which specifically recognizes a distinct protein from mycoplasma hyorhinis, was used to detect mycoplasma infection in different paraffinembedded carcinoma tissues with immunohistochemistry. PCR was applied to amplify the mycoplasma DNA from the positive samples for confirming immunohistochemistry.RESULTS Fifty of 90 cases (56%) of gastric carcinoma were positive for mycoplasma hyorhinis. In other gastric diseases, the mycoplasma infection ratio was 28% (18/49) in chronic superficial gastritis, 30% (14/ 46) in gastric ulcer and 37% (18/ 49) in intestinal metaplasia. The difference is significant with gastric cancer (X2=12.06, P<0.05). In colon carcinoma, the mycoplasma infection ratio was 55.1% (32/58), but it was 20.9% (10/49) in adenomarous polyp (X2=13.46, P<0.005).Gastric and colon cancers with high differentiation had a higher mycoplasma infection ratio than those with low differentiation (P< 0.05). Mycoplasma infection in esophageal cancer, lung cancer, breast cancer and glioma was 50.9% (27/53), 52.6% (31/ 59), 39.7%(25/63) and 41% (38/91), respectively. The mycoplasma DNA was successfully amplified with the DNA extracted from the cancer tissues that were positive for mycoplasma infection (detected with antibody PD4).CONCLUSION There was high correlation between mycoplasma infection and different cancers, which suggests the possibility of an association between the two. The mechanism involved in oncogenesis by mycoplasma remains unknown.

    OBJECTIVE To study the proper sites and doses of intraoperative radiotherapy (IORT) for gastric carcinoma and the effects of this treatment.METHODS A total of 106 cases of stage Ⅰ- Ⅳ gastric carcinoma who received a D2 or D3 radical resection operation combined with IORT were analyzed. Sixty-seven patients with gastric cancer of the antrum and body received distal gastrectomy. The sites of irradiation were at the celiac artery and hepatoduodenal ligament area. Another 39 patients with carcinoma of the cardia and upper part of the gastric body and whole stomach received proximal gastrectomy or total gastrectomy. The sites of irradiation for this group were the upper margin of the pancreas and the regional paraaorta.The therapeutic effects (including survival and complications) of these 106cases who received a combined operation IORT (IORT group) were compared with 441 cases treated during the same time period by a radical resection operation alone (operation group).RESULTS The radiation dose below 30 Gy was safe. The therapeutic method of the operation combined with IORT did not prolong the survival time of patients with stage Ⅱ and Ⅳ gastric cancer, but the 5-year survival rates of patients with stage Ⅱ and Ⅲ gastric cancers were significantly improved.While the 5-year survival rates of the stage Ⅲ cancer patients receiving D2 resection combined with IORT had marked improvement, for those receiving a D3 radical resection, only the postoperative survival rates at 3 and 4 years of those cases in stages Ⅲ cancers were improved (P<0.005-0.001). The 5-year survival rate for those patients was raised only 4.7%(P>0.05).CONCLUSION The 5-year survival rates of patients with stages Ⅱ and Ⅲ gastric carcinoma who received a D2 lymphadenectomy combined with IORT were improved and had no influence on the postoperative complications and mortality.

    The prognosis of metastatic thyroid carcinoma is dependent on the age of the patient, the histologic characteristics of the neoplasm, and the site of metastasis. A more favorable prognosis is found in patients less than 40 years old with follicular carcinoma and without any bony metastases. Metastatic thyroid carcinoma presenting as distal spinal cord compression is extremely rare. We report one such case and review the literature. As reported in the literature, the combination of decompressive laminectomy followed by total thyroidectomy and radioactive iodine therapy has proved to be effective in the treatment of patients with thyroid carcinoma metastatic to the distal vertebral bodies.

    Carcinoma arising primarily from the jaw is a locally aggressive lesion with poor prognosis. Primary intraosseous carcinoma (PIOC) lesion develops either de novo remnants of odontogenic epithelium, odontogenic cyst/tumor, epithelium remnants, or/and salivary gland residues. We describe very interesting case of primary intraosseous carcinoma of mandible. This extensive lesion was sent for oncological opinion and further management. Due to the uncertainty of diagnostic criteria of PIOC, only few cases of this lesion with a typical presentation have been reported. This article presents a case of primary intraosseous carcinoma with a unique appearance and detailed review stating its clinicopathological correlation. PMID:28078158

    Full Text Available Aim: CD44, one of the adhesion molecules, is thought to play an important role in cell-cell and cell-matrix interactions. Matrix metalloproteinases are degradative enzymes that remodel extracellular components. In this study the relation of MMP-2 and CD44 expressions with the histologic classification and the pathologic stage of urothelial carcinoma was revealed using immunohistochemistry.Material and Methods: Thirty-nine patients with urothelial carcinoma of the bladder were studied. The histological classification was performed according to WHO criteria. Patients were grouped as infiltrating urothelial carcinoma, low grade non-invasive papillary urothelial carcinoma, and high grade non-invasive papillary urothelial carcinoma. The pathological staging was done according to the TNM classification. Immunohistochemical staining using CD44 and MMP-2 antibodies was performed on tissue blocks.Results: CD44 immunoreactivity was detected in 77% (30/39 of the tumours which was significantly higher in non-invasive papillary urothelial carcinomas, low grade non-invasive papillary urothelial carcinomas, high grade infiltrating urothelial carcinomas (p≥0.05. MMP-2 expression was observed in 69% (27 of 39 of the tumours. There were no significant differences in MMP-2 expression between various histologic subtypes and noninvasive and infiltrative tumours.Conclusion: In conclusion, higher expression of CD44 is inversely correlated with infiltrative potential of urothelial carcinoma. These results should be supported by further studies.

    Full Text Available Hematoxylin and eosin (H-E stained liver sections of 47 autopsy cases of hepatic malignancies were examined. There were 43 cases of hepatocellular carcinoma (subtypes of 30 trabecular, 7 solid, 5 pseudoglandular, and one scirrhous carcinoma, 3 of cholangiocellular carcinoma and one of mixed carcinoma. After immunohistochemical staining, benign hepatocytes reacted positively with anti-epithelial membrane antigen (EMA. Hepatocellular carcinoma cells reacted more weakly than benign hepatocytes. It was noted that the microtubular structure, which could not be demonstrated even by alcian blue or cationic ferric hydroxide colloid stabilized with cacodylate (Fe-CaC, was clearly detected with anti-EMA. The EMA-positive microtubular structures may indicate terminal cholangiolar differentiation. Based on EMA, seven more cases formerly classified as hepatocellular carcinoma by H-E were reclassified as mixed carcinoma, totaling eight (17.0%. The histologic classification of "mixed carcinoma" has been 1.5 to 2.0% of primary liver cancers in Japan, but we suggest there may be more cases of "mixed carcinoma" identified in the future. In conclusion, we emphasize that EMA staining is useful for more accurate classification of hepatic tumors.

    Full Text Available Xp11 translocation renal cell carcinoma (TRCC is a rare subtype of renal cell carcinoma characterized by chromosomal translocations involving the TFE3 gene located at the Xp11.2 locus. Initial cases were more common in children, but cases in older adults have begun to accrue and suggest a relatively more aggressive course. We report a case of Xp11 TRCC in a 63-year-old female patient with initial presentation mimicking upper urinary tract urothelial cell carcinoma, with biopsy proving TRCC. She underwent a radical nephrectomy and paracaval lymph node dissection and is followed up with the intent to initiate vascular endothelial growth factor–targeted therapy in case of recurrence.

    Nouf Hijazi, MD

    2014-12-01

    Full Text Available In the salivary gland, a key differential feature of Mammary analog secretory carcinoma (MASC from acinic cell carcinoma (ACC is the lack of cytoplasmic granules. We report a case of a parotid mass incorrectly diagnosed on fine needle aspirate as acinic cell carcinoma due to many cells with basophilic granules suggesting serous acinar differention. Tumor resection revealed a tumor consistent with low grade adenocarcinoma that had eosinophilic, microvacuolar cytoplasm with distinct basophilic granules staining with PASD and mucicarmine. The diagnosis of MASC was confirmed with stains for GCDF-15, mammoglobin, and S100 and FISH consistent with a t(12;15 translocation. Relying on the absence of cytoplasmic granules as a feature to distinguish ACC from MASC is a diagnostic pitfall.

    Since its discovery 50 years ago, Epstein-Barr virus (EBV) has been linked to the development of cancers originating from both lymphoid and epithelial cells. Approximately 95% of the world’s population sustains an asymptomatic, life-long infection with EBV. The virus persists in the memory B-cell pool of normal healthy individuals, and any disruption of this interaction results in virus-associated B-cel tumors. The association of EBV with epithelial cel tumors, specifical y nasopharyngeal carcinoma (NPC) and EBV-positive gastric carcinoma (EBV-GC), is less clear and is currently thought to be caused by the aberrant establishment of virus latency in epithelial cells that display premalignant genetic changes. Although the precise role of EBV in the carcinogenic process is currently poorly understood, the presence of the virus in al tumor cel s provides opportunities for developing novel therapeutic and diagnostic approaches. The study of EBV and its role in carcinomas continues to provide insight into the carcinogenic process that is relevant to a broader understanding of tumor pathogenesis and to the development of targeted cancer therapies.

    AIM: To investigate the expression of c-myc target from laryngeal cancer cells (MTLC) gene in gastric carcinoma (GC)tissues and the effect of MTLC over-expression on gastric carcinoma cell line BGC823.METHODS: RT-PCR was performed to determine the expression of MTLC mRNA in GC and matched control tissues.BGC823 cells were transfected with an expression vector pcDNA3.1-MTLC by liposome and screened by G418. Growth of cells expressing MTLC was observed daily by manual counting. Apoptotic cells were determined by TdT-mediated dUTP nick-end labeling (TUNEL) assay.RESULTS: The expression of MTLC mRNAs was downregulated in 9(60%) of 15 cases of GC tissues. The growth rates of the BGC823 cells expressing MTLC were indistinguishable from that of control cells. A marked acceleration of apoptosis was observed in MTLC-expressing cells.CONCLUSION: MTLC was down-regulated in the majority of GC tissues and could promote apoptosis of GC cell lines,which suggests that MTLC may play an important role in the carcinogenesis of gastric carcinoma.

    Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

    Follicular carcinomas are the second most common form of thyroid cancer, accounting for 10 to 20% of all thyroid cancers. Follicular carcinomas have a propensity to metastasize via the bloodstream, spreading to bone, lungs, liver, and elsewhere. We described the case of a 48-year-old woman who presented with swelling of the left pre auricular area, which was a consequence of a metastatic follicular carcinoma of the masticator space. Plain films showed ill defined erosive bony changes from the left condylar head to the mandibular notch. Contrast-enhanced CT images showed a well circumscribed round mass with well enhancement within left masticator space. On MR images, the mass was heterogenously hyperintense to the muscle on T2-weighted images and isointense or hyperintense to the muscle on T1-weighted images, and showed good enhancement on contrast-enhanced T1-weighted images. Upon microscopic examination, the metastatic mass was found to be composed of fairly uniform cells forming small follicles containing colloid, showing capsular and vascular invasion.

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    Full Text Available Introduction & Background: Fibrolamellar hepatocel-lular carcinoma occurs in non-cirrhotic livers, most frequently in the adolescents or young adults without sex predominance, and the prognosis is more favor-able than that of the usual hepatocellular carcinoma. It is a rare condition; accounting for less than 1% of primary liver cancers. Case Presentation: This is a seventeen-year old male patient with history of right upper quadrant abdomi-nal pain, with no hepatomegaly. Liver function tests and serological markers for viral B, C hepatitis and tumor markers were normal. CT scan demonstrated a massive hyper- vascular lesion in the liver and the histological examination was reported as a typical fibrolamellar hepatocarcinoma. Intra-arterial chemo-therapy has been done for the patient about 6 months ago. Now he had none of the previous problems and his weight loss is reversed. Fibrolamellar hepatocellu-lar carcinoma should be kept in mind in young pa-tients with hypervascular liver masses and no history of hepatic diseases.

    1982-05-01

    CT scans of 36 carcinomas of the laryngo-pharyngeal region were analysed retrospectively and the results compared with the endoscopic and operative findings. For the final tumour staging in 18 cases of carcinoma of the larynx equivalent results were obtained in 12 cases; CT scans offered a better evaluation in two cases and insufficient dates in four. Destruction of cartilagineous structures, submucosal tumour infiltration and the pre-epiglottic space are better shown on CT scans. Faulty evaluation of tumour presence of extent are due to superficial tumour growth or to motion artefacts. For the final staging of 18 carcinomas of the pharynx results of CT and clinical findings were comparable in nine cases. CT was less precise in five and superior to endoscopy in four. Evaluation of neoplastic infiltration of the parapharyngeal soft-tissue and of the skull base was the main advantage of CT scanning. Low grade tumours of the oro- and hypopharynx were not visible on CT and tumours of the base of the tongue were insufficiently displayed.

  18. Histopathological transformation to small-cell lung carcinoma in non-small cell lung carcinoma tumors.

    2016-08-01

    Lung cancer is the principal cause of cancer-related death worldwide. The use of targeted therapies, especially tyrosine kinase inhibitors (TKIs), in specific groups of patients has dramatically improved the prognosis of this disease, although inevitably some patients will develop resistance to these drugs during active treatment. The most common cancer-associated acquired mutation is the epidermal growth factor receptor (EGFR) Thr790Met (T790M) mutation. During active treatment with targeted therapies, histopathological transformation to small-cell lung carcinoma (SCLC) can occur in 3-15% of patients with non-small-cell lung carcinoma (NSCLC) tumors. By definition, SCLC is a high-grade tumor with specific histological and genetic characteristics. In the majority of cases, a good-quality hematoxylin and eosin (H&E) stain is enough to establish a diagnosis. Immunohistochemistry (IHC) is used to confirm the diagnosis and exclude other neoplasia such as sarcomatoid carcinomas, large-cell carcinoma, basaloid squamous-cell carcinoma, chronic inflammation, malignant melanoma, metastatic carcinoma, sarcoma, and lymphoma. A loss of the tumor-suppressor protein retinoblastoma 1 (RB1) is found in 100% of human SCLC tumors; therefore, it has an essential role in tumorigenesis and tumor development. Other genetic pathways probably involved in the histopathological transformation include neurogenic locus notch homolog (NOTCH) and achaete-scute homolog 1 (ASCL1). Histological transformation to SCLC can be suspected in NSCLC patients who clinically deteriorate during active treatment. Biopsy of any new lesion in this clinical setting is highly recommended to rule out a SCLC transformation. New studies are trying to assess this histological transformation by noninvasive measures such as measuring the concentration of serum neuron-specific enolase.

  20. KRAS gene mutations are more common in colorectal villous adenomas and in situ carcinomas than in carcinomas

    Zauber, Peter; Marotta, Stephen; Sabbath-Solitare, Marlene

    2013-01-01

    We have evaluated the frequency of KRAS gene mutations during the critical transition from villous adenoma to colorectal carcinoma to assess whether the adenomas contain a KRAS mutation more frequently than carcinomas. We analyzed sporadic villous and tubulovillous adenomas, in situ carcinomas, and primary colorectal carcinomas from multiple patients. The cancers were further evaluated for mucinous status and microsatellite instability. Standard PCR molecular techniques were used for KRAS and microsatellite analyses. A KRAS mutation was found in 61.9% of 134 adenomas, 67.8% of 84 in situ carcinomas, and just 31.6% of 171 carcinomas. Our study clearly demonstrates that tubulovillous and villous adenomas, as well as both the benign and malignant parts of in situ carcinomas, are statistically more likely to contain a somatic KRAS gene mutation than colorectal carcinomas. This difference is confined to the non-mucinous and the microsatellite stable tumors. Our data support the possibility that non-mucinous and microsatellite stable carcinomas with wild-type KRAS gene may have had a mutation in the KRAS gene during their earlier stages, with the mutation lost during further growth.
