    Wernicke encephalopathy is a disease that constitutes a medical emergency, but one that can be reversed with thiamine repletion if it is recognized early. Patients with cancer have a high risk of Wernicke encephalopathy because of malnutrition, the use of chemotherapeutic agents, and disease progression. Korsakoff syndrome can follow or accompany Wernicke encephalopathy. Although patients can recover from Wernicke encephalopathy via rapid repletion of thiamine, few patients recover from Korsakoff syndrome. Here, the case of a 76-year-old female patient who had primary peritoneal cancer and developed Wernicke-Korsakoff syndrome as a result of prolonged nutritional imbalance and fast-growing tumor cells is reported. The patient's neurologic symptoms improved, but she did not recover from the psychiatric effects of the disease. PMID:24474922

    2014-07-01

    During recent years paramount changes have occurred in the pathogenesis of ovarian cancer and recent clinical studies identified new prognostic factors. Consequently, the FIGO has established a new staging system collectively covering carcinomas derived from the ovaries, the fallopian tubes and primary peritoneal cancers as well as malignant ovarian germ cell and sex-cord stromal tumors. The new staging system started on 01 January 2014. Major changes occurred in the FIGO IC/T1c stage with surgical spill (FIGO IC1/T1c1) versus capsule ruptured before surgery or tumor on ovarian or fallopian tube surface (FIGO IC2/T1c2) versus malignant cells in the ascites or peritoneal washings (FIGO IC3/T1c3). The regional lymph node metastases were subcategorised using a cut-off value of 10 mm as the largest dimension of the metastatic deposits. Distant metastases (excluding peritoneal metastases) were substaged as FIGO IVA/M1a in cases of cytologically or histologically proven pleural involvement and as FIGO IVB/M1b in cases of parenchymal metastases and metastases in extra-abdominal organs (including lymph nodes outside the peritoneal cavity and the inguinal lymph nodes).

    2015-08-01

    Primary peritoneal cancer (PPC) is considered a very rare condition, with mesotheliomas deemed the only true PPC when considering the cellular content and embryological derivation of the peritoneum. However, in women, PPC are seen in much greater abundance than that in men and the type of cancer detected is often that of a serous epithelial carcinoma, histologically similar to serous ovarian carcinomas. The management is also similar, i.e. surgery and platin-based chemotherapy. The definition clinically of PPC is that of widespread carcinomatosis with normal-sized ovaries. The carcinomatosis is often extensive, and the only bulk disease may be within the omentum and achieving complete clearance of all disease at primary surgery unlikely. Thus, the concept of using chemotherapy as the main strategy is a reasonable approach and may well be the best single therapeutic option in some patients. This paper reviews the data on PPC and how this approach could be assessed. PMID:26045131

    Full Text Available Peritoneal surface malignancy results from seeding of gastrointestinal cancer or abdomino-pelvic sarcoma, or it can occur as a primary disease, such as peritoneal mesothelioma. In the past, this clinical situation was treated only with palliative intent. Actual treatment options for surgical management uses cytoreductive surgery which combines peritonectomy and visceral resection in an effort to remove all visible cancer within the abdomen and pelvis. Then the peritoneal cavity is flooded with chemotherapy solution. To select patients for this agressive approach quantitative prognostic indicators for carcinomatosis must be evaluated. The peritoneal cancer index (PCI is a synthesis of the distribution of tumor and a lesion size score. In such conditions abdominal medium contrast computed-tomography it is very helpful in identification of neoplasic implants.

  18. Comparison of the MRI and Integrated PET/CT Findings in the Preoperative Detection of Peritoneal Carcinomatosis Arising from Primary Ovarian Cancer

    International Nuclear Information System (INIS)

    To compare the diagnostic performance of MRI and integrated PET/CT for the preoperative detection of peritoneal carcinomatosis arising from primary ovarian cancer. Twenty-three patients with suspected ovarian tumors underwent a contrast-enhanced 1.5 Tesla MRI and a 18F-fluorodeoxyglucose (FDG) PET/CT prior to surgery. The peritoneal cavity was subdivided into six specific sites for a lesion- based analysis. The imaging findings were compared statistically with the histopathological findings using McNemar's test with Bonferroni's adjustment and generalized estimation equations. The histopathological results of all 23 patients were confirmed for primary malignant epithelial ovarian cancer. Of the 23 patients, 19 had a total of 83 sites with peritoneal seedings throughout the abdomen and pelvis. The comparison of the patient- based sensitivity, specificity and accuracy of the use of MRI versus PET/CT for the detection of peritoneal carcinomatosis were 95% versus 84% (p > 0.05; N.S.), 50% versus 50% (p > 0.05; N.S.), and 87% versus 78% (p > 0.05; N.S.), respectively. Moreover, the comparison of the lesion-based sensitivity, specificity and accuracy of MRI versus integrated PET/CT were 86% and 75% (p = 0.004), 76% and 84% (p > 0.05; N.S.), and 82% and 78% (p > 0.05; N.S.), respectively. We found that MRI was more sensitive than integrated PET/CT for the detection of preoperative peritoneal carcinomatosis arising from primary ovarian cancer

    Full Text Available Abstract Background Pharmacokinetic advantages of intraperitoneal (IP rhIL-12, tumor response to IP delivery of other cytokines as well as its potential anti-angiogenic effect provided the rationale for further evaluation of IPrhIL-12 in patients with persistent ovarian or peritoneal carcinoma. Methods A phase 2 multi-institutional trial (NCI Study #2251 of IP rIL-12 (300 nanogram/Kg weekly was conducted in patients with ovarian carcinoma or primary peritoneal carcinoma. Patients treated with primary therapy for ovarian cancer who had no extraabdominal/parenchymal disease or bulky peritoneal disease were eligible. Four to 8 weeks from last chemotherapy, eligible patients underwent a laparotomy/laparoscopy. Patients with residual disease ≤ 1 cm were registered for the treatment phase 2–5 weeks post surgery. The effect of IP rIL-12 on the expression of TNFα , INFα , IL-10, IP-10, IL-8, FGF, VEGF was also studied. Results Thirty-four patients were registered for the first screening phase of the study. Median age was 56.6 years (range: 31–71; 12 completed the second phase and were evaluable for response/toxicity. Performance scores of IL-12 treated patients were 0 (11 pts and 1 (1 pt. There were no treatment related deaths, peritonitis or significant catheter related complications. Toxicities included grade 4 neutropenia (1, grade 3 fatigue (4, headache (2, myalgia (2, non-neutropenic fever (1, drug fever (1, back pain (1, and dizziness (1. The best response observed was SD. Two patients had SD and 9 had PD, and 1 was evaluable for toxicity only. Peritoneal fluid cytokine measurements demonstrated a ≥ 3 fold relative increase post-rhIL-12: IFN-γ, 5/5 pts; TNF-α , 1/5; IL-10, 4/5; IL-8, 5/5; and VEGF, 3/5. IP10 levels were increased in 5/5 patients. Cytokine response profiles suggest either NK or T-cell mediated effects of IP rhIL-12.

    Gastric cancer is one of the most aggressive cancers and is the second leading cause of cancer death worldwide. Approximately 40% of global gastric cancer cases occur in China, with peritoneal metastasis being the prevalent form of recurrence and metastasis in advanced disease. Currently, there are limited clinical approaches for predicting and treatment of peritoneal metastasis, resulting in a 6-month average survival time. By comprehensive genome analysis will uncover the pathogenesis of peritoneal metastasis. Here we describe a comprehensive whole-genome and transcriptome sequencing analysis of one advanced gastric cancer case, including non-cancerous mucosa, primary cancer and matched peritoneal metastatic cancer. The peripheral blood is used as normal control. We identified 27 mutated genes, of which 19 genes are reported in COSMIC database (ZNF208, CRNN, ATXN3, DCTN1, RP1L1, PRB4, PRB1, MUC4, HS6ST3, MUC17, JAM2, ITGAD, IREB2, IQUB, CORO1B, CCDC121, AKAP2, ACAN and ACADL), and eight genes have not previously been described in gastric cancer (CCDC178, ARMC4, TUBB6, PLIN4, PKLR, PDZD2, DMBT1and DAB1).Additionally,GPX4 and MPND in 19q13.3-13.4 region, is characterized as a novel fusion-gene. This study disclosed novel biological markers and tumorigenic pathways that would predict gastric cancer occurring peritoneal metastasis. PMID:26330360

  14. Prospective evaluation of contrast-enhanced MRI in the depiction of peritoneal spread in primary or recurrent ovarian cancer

    International Nuclear Information System (INIS)

    The purpose of this study was to assess the accuracy of MRI in the staging of intra-abdominal tumor seeding of ovarian carcinoma. Fifty-seven patients with suspected primary or recurrent ovarian carcinoma were included in this study. All patients received laparotomy within 8 weeks after MRI. The MRI protocol included fat-saturated T1-weighted spin-echo (SE) sequences pre- and post i.v. application of gadopentetate dimeglumine. The criteria for tumor manifestation was contrast enhancement of intra-abdominal soft tissue lesions or peritoneum. The image review was performed by a blinded radiologist, a specialist in gynecological and abdominal MR imaging. Results were compared with findings during laparotomy. Sensitivity, specificity, positive and negative predictive values, and corresponding 95% confidence intervals were calculated for single intra-abdominal locations and for groups of locations defined according to surgical strategies for intra-abdominal cytoreduction. Laparotomy and histopathology confirmed 251 abdominal tumor locations. Sensitivity was high in lower pelvis locations (73-83%) except for ureter or bladder infiltration (40%). Bowel or mesentery locations displayed sensitivity values from 73 to 77%. Sensitivity was very low for pelvic lymph nodes (28%), greater omentum (38%), and lesser sac (43%). Magnetic resonance imaging based on contrast-enhanced fat-saturated T1 SE sequences improves planning of cytoreduction preceding chemotherapy in advanced primary or relapsed ovarian carcinoma.

    Background: Although literature does not provide a level-1 evidence to support either method of closure, various studies have shown a reduced frequency of superficial surgical site infection with delayed primary closure (DPC) as opposed to primary closure (PC). Nevertheless, PC is still preferred by most. surgeons to avoid a second procedure. This study was conducted with the objective to compare the frequency of wound infection and duration of hospitalization among patients undergoing primary and delayed primary closure of the skin wound following laparotomy for peritonitis. Method: A randomized controlled trial comprising 70 patients: Thirty-five patients underwent PC (Group-A) and 35 DPC (Group-B). Frequency of wound infection during follow up period and duration of hospital stay was noted in both groups. Results: In group-A, 18 (51.43 percentage) patients showed wound infection while in group-B, it was 9 (25.71 percentage) with p=0.027. Mean hospital stay recorded in group-A was 7.03 days ± 1.81, and for group-B, it was 6.34 days±4.14 (p=0.372). Conclusion: DPC for surgical wounds is better than PC technique as it decreases the frequency of wound infection during follow-up period without any significant increase in duration of hospital stay.

  16. Aberrant expression of Cx43 is associated with the peritoneal metastasis of gastric cancer and Cx43-mediated gap junction enhances gastric cancer cell diapedesis from peritoneal mesothelium.

    Directory of Open Access Journals (Sweden)

    Bo Tang

    Full Text Available The process of peritoneal metastasis involves the diapedesis of intra-abdominal exfoliated gastric cancer cells through the mesothelial cell monolayers; however, the related molecular mechanisms for this process are still unclear. Heterocellular gap-junctional intercellular communication (GJIC between gastric cancer cells and mesothelial cells may play an active role during diapedesis. In this study we detected the expression of connexin 43 (Cx43 in primary gastric cancer tissues, intra-abdominal exfoliated cancer cells, and matched metastatic peritoneal tissues. We found that the expression of Cx43 in primary gastric cancer tissues was significantly decreased; the intra-abdominal exfoliated cancer cells and matched metastatic peritoneal tissues exhibited increasing expression compared with primary gastric cancer tissues. BGC-823 and SGC-7901 human gastric cancer cells were engineered to express Cx43 or Cx43T154A (a mutant protein that only couples gap junctions but provides no intercellular communication and were co-cultured with human peritoneal mesothelial cells (HPMCs. Heterocellular GJIC and diapedesis through HPMC monolayers on matrigel-coated coverslips were investigated. We found that BGC-823 and SGC-7901 gastric cancer cells expressing Cx43 formed functional heterocellular gap junctions with HPMC monolayers within one hour. A significant increase in diapedesis was observed in engineered Cx43-expressing cells compared with Cx43T154A and control group cells, which suggested that the observed upregulation of diapedesis in Cx43-expressing cells required heterocellular GJIC. Further study revealed that the gastric cancer cells transmigrated through the intercellular space between the mesothelial cells via a paracellular route. Our results suggest that the abnormal expression of Cx43 plays an essential role in peritoneal metastasis and that Cx43-mediated heterocellular GJIC between gastric cancer cells and mesothelial cells may be an

    We report the imaging findings of two recent cases of primary bacterial peritonitis in otherwise healthy children with a clinical presentation mimicking acute appendicitis. Primary bacterial peritonitis is rare in the absence of underlying systemic disease. Although it has been described in the pediatric literature, the imaging findings have not been described in the radiological literature to the best of our knowledge. With imaging playing an increasing role in the evaluation of appendicitis in children, it is important for the radiologist to be familiar with this inflammatory process. (orig.)

    Peritoneal carcinomatosis is one of the most common routes of dissemination of colorectal cancer (CRC). It is encountered in 7% of patients at primary surgery, while it develops in about 4% to 19% of patients after curative surgery and in up to 44% of patients with recurrent CRC. Peritoneal involvement from colorectal malignancies has been considered traditionally as a manifestation of terminal disease, due to limited response to conventional surgical and chemotherapeutic treatments. In the past few years t...

    Hydatid cyst disease is a zoonotic disease caused by Echinococcus granulosus, E.multilocularis or E.Vogli. The most common primary site is liver (75%) followed by lungs (5-15%) and other organs constitute 10-20%. Peritoneal hydatid cysts are very rare especially primary peritoneal hydatid. Secondary peritoneal hydatid cysts are relatively common, which usually occurs due to rupture of primary hepatic hydatid cyst. We present a rare case of large primary peritoneal hydatid cyst misdiagnosed as...

  1. Evaluation of preoperative computed tomography in estimating peritoneal cancer index in peritoneal carcinomatosis

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the utility of CT of peritoneal carcinomatosis (PC) by comparing preoperative radiological and intraoperative peritoneal cancer index (PCI) scores. This study collected 76 patients of PC from different disease origins. The sensitivity, specificity and accuracy were calculated in each of the abdominopelvic region, and by tumor histologic type. An overall sensitivity of CT was 69%. The detection rate was highest in appendix and lowest in stomach group (84% and 47%, respectively) by the origin of primary disease. There was a lower detection rate (59% vs 79%, p=0.001), and a higher underestimation rate (29% vs 21%, p<0.05) of small bowel lesion compared with overall abdomino-pelvic region. CT predicted an individual regional PCI score accurately in 65%, underestimated in 24%, and overestimated in 11%. CT detection rate in small tumor (<0.5 cm) was 29%, and increased to 97% with nodules size exceeding 5 cm. CT significantly underestimated the clinical PCI value in overall. The sensitivity of CT in detecting PC was influenced by histologic type, tumor location and size. CT underestimated the clinical PCI score in PC patient. (author)

    Occurring either synchronously or metachronously to the primary tumor, peritoneal metastases (PM) are diagnosed in 8 to 20 % of the patients with colorectal cancer (CRC). Prognosis of these patients appears to be worse than those with other sites of metastases. While systemic therapy has shown significant prolongation of survival in patients with stage IV colorectal cancer, the outcomes in the subset of patients with PM has been much inferior. Over the last 2 decades, cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) have been effective in substantially prolonging survival in patients with colorectal PM and have the potential to cure certain patients as well. This article reviews the current evidence for CRS and HIPEC to treat colorectal PM as well as future research going on in this form of locoregional treatment. PMID:27065708

    Full Text Available Primary peritoneal serous carcinoma (PPSC is a rare primary malignancy that diffusely involves the peritoneum, indistinguishable clinically and histopathologically from primary serous ovarian carcinoma. The origin of PPSC has not been well characterized. Here we present a case of PPSC diagnosed in ultrasonography-guided fine needle aspiration cytology (FNAC in a 76- old female presenting with ascites, abdominal pain, distension and constipation. PPSC is an unusual tumour but cytomorphology is distinctive enough to diagnose preoperatively. In the case report hereby described PPSC is an inoperable malignancy, hence chemotherapy and palliative care are the only offered treatment.

  5. Pelvic-peritoneal tuberculosis mimicking ovarian cancer

    International Nuclear Information System (INIS)

    Pelvic-peritoneal tuberculosis is a common extrapulmonary site in young females mimicking an advanced ovarian malignancy. We present 2 cases with the classical triad of advanced-stage ovarian carcinoma-ascites, abdominopelvic masses and elevated serum CA-125 levels. Laparoscopic examination revealed peritoneal nodules which on biopsy showed granulomatous inflammation and no malignant cells. Patients were started on anti-tuberculous therapy and on follow-up their symptoms as well as CA-125 levels normalized. Medical awareness of peritoneal tuberculosis is lacking and many young women with this disease undergo unnecessary extended surgery. Diagnostic laparoscopy combined with peritoneal biopsy seems to be a sufficient and safe method to provide a definitive diagnosis for this curable infection. If left untreated, the disease may disseminate and result in significant organ dysfunctions particularly infertility. (author)

    2015-01-01

    The pattern of ovarian cancer metastasis is markedly different from that of most other epithelial tumors, because it rarely spreads hematogenously. Instead, ovarian cancer cells exfoliated from the primary tumor are carried by peritoneal fluid to metastatic sites within the peritoneal cavity. These sites, most notably the abdominal peritoneum and omentum, are organs covered by a mesothelium-lined surface. To investigate the processes of ovarian cancer dissemination, we assembled a complex three-dimensional culture system that reconstructs the lining of the peritoneal cavity in vitro. Primary human fibroblasts and mesothelial cells were isolated from human omentum. The fibroblasts were then mixed with extracellular matrix and covered with a layer of the primary human mesothelial cells to mimic the peritoneal and omental surfaces encountered by metastasizing ovarian cancer cells. The resulting organotypic model is, as shown, used to examine the early steps of ovarian cancer dissemination, including cancer cell adhesion, invasion, and proliferation. This model has been used in a number of studies to investigate the role of the microenvironment (cellular and acellular) in early ovarian cancer dissemination. It has also been successfully adapted to high throughput screening and used to identify and test inhibitors of ovarian cancer metastasis. PMID:26780294

    2004-06-01

    Full Text Available Abstract Epithelial ovarian cancer (EOC is a significant cause of cancer related morbidity and mortality in women. Preferential involvement of peritoneal structures contributes to the overall poor outcome in EOC patients. Advances in biotechnology, such as cDNA microarray, are a product of the Human Genome Project and are beginning to provide fresh opportunities to understand the biology of EOC. In particular, it is now possible to examine in depth, at the molecular level, the complex relationship between the tumor itself and its surrounding microenvironment. This review focuses on the anatomy, physiology, and current immunobiologic research of peritoneal structures, and addresses certain potentially useful animal models. Changes in both the inflammatory and non-inflammatory cell compartments, as well as alterations to the extracellular matrix, appear to be signal events that contribute to the remodeling effects of the peritoneal stroma and surface epithelial cells on tumor growth and spread. These alterations may involve a number of proteins, including cytokines, chemokines, growth factors, either membrane or non-membrane bound, and integrins. Interactions between these molecules and molecular structures within the extracellular matrix, such as collagens and the proteoglycans, may contribute to a peritoneal mesothelial surface and stromal environment that is conducive to tumor cell proliferation and invasion. These alterations need to be examined and defined as possible prosnosticators and as therapeutic or diagnostic targets.

  10. Copy number variation analysis of matched ovarian primary tumors and peritoneal metastasis.

    Directory of Open Access Journals (Sweden)

    Joel A Malek

    Full Text Available Ovarian cancer is the most deadly gynecological cancer. The high rate of mortality is due to the large tumor burden with extensive metastatic lesion of the abdominal cavity. Despite initial chemosensitivity and improved surgical procedures, abdominal recurrence remains an issue and results in patients' poor prognosis. Transcriptomic and genetic studies have revealed significant genome pathologies in the primary tumors and yielded important information regarding carcinogenesis. There are, however, few studies on genetic alterations and their consequences in peritoneal metastatic tumors when compared to their matched ovarian primary tumors. We used high-density SNP arrays to investigate copy number variations in matched primary and metastatic ovarian cancer from 9 patients. Here we show that copy number variations acquired by ovarian tumors are significantly different between matched primary and metastatic tumors and these are likely due to different functional requirements. We show that these copy number variations clearly differentially affect specific pathways including the JAK/STAT and cytokine signaling pathways. While many have shown complex involvement of cytokines in the ovarian cancer environment we provide evidence that ovarian tumors have specific copy number variation differences in many of these genes.

    Malignant mesothelioma of the peritoneum is a rare neoplasm with a rapidly fatal course. The tumour arises from the mesothelial cells lining the pleura and peritoneum or, rarely, in the pericardium or tunica vaginalis. This neoplasm is characterized by being difficult to diagnose, having a rapid evolution and a poor response to therapy. Mesothelioma is very glucose avid, and malignant pleural mesothelioma has been reported concerning the utility of F-18 FDG PET or PET/CT. But little has been known about the imaging finding of malignant peritoneal mesothelioma on F-18 FDG PET/CT. We report a case of malignant peritoneal mesothelioma mimicking peritoneal carcinomatosis of F-18 FDG PET/CT.

    Full Text Available Primary peritonitis remains a rare disease in otherwise healthy children, with group A Streptococcus (GAS being a particularly unusual cause. A case involving a 14-year-old girl, who presented with an ‘acute abdomen’ and was taken to the operating room for urgent laparoscopy, is reported. Abdominal and pelvic structures were only minimally inflamed, as was the appendix. Peritoneal fluid and blood cultures both grew pure cultures of GAS. The patient’s course was complicated by streptococcal toxic shock syndrome. She fortunately made a full recovery. The present report highlights the diagnostic and treatment dilemmas associated with GAS primary peritonitis.

    Cystic lesions within the peritoneum have been classified classically according to their lining on histology into four categories-endothelial, epithelial, mesothelial, and others (germ cell tumors, sex cord gonadal stromal tumors, cystic mesenchymal tumors, fibrous wall tumors, and infectious cystic peritoneal lesions). In this article, we will proceed to classify cystic peritoneal lesions focusing on the degree of radiological complexity into three categories-simple cystic, mildly complex, and cystic with solid component lesions. Many intra-abdominal collections within the peritoneal cavity such as abscess, seroma, biloma, urinoma, or lymphocele may mimic primary peritoneal cystic masses and need to be differentiated. Clinical history and imaging features may help differentiate intra-abdominal collections from primary peritoneal masses. Lymphangiomas are benign multilocular cystic masses that can virtually occur in any location within the abdomen and insinuate between structures. Ultrasound may help differentiate enteric duplication cysts from other mesenteric and omental cysts in the abdomen. Double-layered wall along the mesenteric side of bowel may suggest its diagnosis in the proper clinical setting. Characteristic imaging features of hydatid cysts are internal daughter cysts, floating membranes and matrix, peripheral calcifications, and collagenous pericyst. Non-pancreatic psuedocysts usually have a fibrotic thick wall and chylous content may lead to a fat-fluid level. Pseudomyxoma peritonei appears as loculated fluid collections in the peritoneal cavity, omentum, and mesentery and may scallop visceral surfaces. Many of the primary cystic peritoneal masses have specific imaging features which can help in accurate diagnosis and management of these entities. Knowledge of the imaging spectrum of cystic peritoneal masses is necessary to distinguish from other potential cystic abdominal mimicker masses. PMID:25269999

  2. Peritoneal carcinosis

    International Nuclear Information System (INIS)

    Abdominal CT yields several pieces of information for the diagnosis of secundary neoplastic involvement of the peritoneum (peritoneal car-cinosis). Peritoneal carcinosis may be the first clinical sign of an occult primary tumor. CT scans of 120 patients with peritoneal car-cinosis confirmed by pre/peri-operative biopsy or at autopsy, were retrospectively reviewed. The CT patterns of peritoneal carcinosis were detected in 20 of 44 patients with an occult malignancy. In 16 of 76 cases with a known malignancy there was no evidence of secondary peritoneal involvement. The incidence of CT findings and their correlation with the primary tumor are critically discussed. The authors have assessed the utility of CT in detecting peritoneal carcinosis, even though in their experience CT findings of secondary neoplastic peritoneal involvement could not be correlated with a primary tumor

    Full Text Available Background. Peritoneal Carcinomatosis Index (PCI is a widely established scoring system that describes disease burden in isolated colorectal peritoneal carcinomatosis (CPC. Its significance may be diminished with complete cytoreduction. We explore the utility of the recently described Peritoneal Surface Disease Severity Score (PSDSS and compare its prognostic value against PCI. Methods. The endpoints were overall survival (OS, progression-free survival (PFS, and survival less than 18 months (18 MS. Results. Fifty patients underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC for CPC from 2003 to 2014, with 98% achieving complete cytoreduction. Median OS was 28.8 months (95% CI, 18.0–39.1; median PFS was 9.4 months (95% CI, 7.7–13.9. Univariate analysis showed that higher PCI was significantly associated with poorer OS (HR 1.11; 95% CI, 1.03–1.20 and PFS (HR 1.09; 95% CI, 1.03–1.14. Conversely, PSDSS was not associated with either endpoint. Multivariate analysis showed that PCI, but not PSDSS, was predictive of OS and PFS. PCI was also able to discriminate survival outcomes better than PSDSS for both OS and PFS. There was no association between 18 MS and either score. Conclusion. PCI is superior to PSDSS in predicting OS and PFS and remains the prognostic score of choice in CPC patients undergoing CRS/HIPEC.

  5. Establishment and identification of a rabbit model of peritoneal carcinomatosis from gastric cancer

    International Nuclear Information System (INIS)

    Gastric cancer peritoneal carcinomatosis is a common clinical problem, but there are no suitable large animal models to study this problem. This study was to establish a stable rabbit peritoneal carcinomatosis model of gastric cancer using VX2 tumor, and analyze the clinico-pathological features. VX2 tumor was implanted into 36 New Zealand rabbits by 3 methods: laparotomic orthotopic injection of cancer cells into the submucosal layer of the stomach (Group A), laparotomic implantation of tumor tissue into the greater omentum immediately beneath the gastric antrum (Group B), and percutaneous injection of tumor cells directly into the peritoneal cavity (Group C), 12 rabbits in each group. The animals were closely observed and detailed clinico-pathological studies were conducted. The success rates of peritoneal carcinomatosis formation were 100% (12/12), 91.7% (11/12) and 58.3% (7/12), respectively, for Groups A, B and C (P = 0.019, A versus C; P = 0.077, B versus C; P = 0.500, A versus B, Fisher's exact test). Two weeks after submucosal cancer cells injection in Group A, ulcerative gastric cancer with peritoneal carcinomatosis showed typical VX2 tumor pathology, with widespread intraperitoneal metastatic nodules, bloody ascites and perspicuous pulmonary metastases. The clinico-pathological progression pattern was very similar to patients of advanced gastric cancer with peritoneal carcinomatosis. Groups B and C showed similar pattern of cancer progression, but less aggressive. First large animal model of peritoneal carcinomatosis from gastric cancer has been established by laparotomic orthotopic injection of VX2 cancer cells into the submucosal layer of the stomach, providing a more suitable model for surgical interventional studies. The clinico-pathological features of this model resemble human peritoneal carcinomatosis

    Background Gastric cancer is the 2nd leading cause of cancer death worldwide. Malignant bowel obstruction (mbo) is a common complication in advanced gastric cancer because of peritoneal dissemination. A multicentre prospective study reported that patients with peritoneal dissemination of gastric origin survive for a median of 3.1 months. The aim of the present study was therefore to evaluate the efficacy and safety of metronomic combination chemotherapy with 5-fluorouracil and cisplatin in inoperable mbo from peritoneal dissemination in gastric cancer. Methods Gastric cancer patients diagnosed with inoperable mbo because of peritoneal dissemination were treated with infusional 5-fluorouracil 300 mg/m2 daily on days 1–5 and 8–12, and cisplatin 5 mg/m2 daily on days 1–4 and 8–11 every 3 weeks. The primary endpoint was symptom control (remission of obstruction); the secondary endpoint was symptom control time and survival; the tertiary endpoint was adverse effects. Results Between January 2013 and December 2014, 26 patients received the study treatment. Before treatment, 18 patients (69.2%) were nil per os, and 8 (30.8%) could consume liquids. After a mean of 3.3 cycles of the study treatment, just 4 patients (15.4%) was still nil per os. Of the remaining 22 patients, 3 (11.5%) could consume liquids, 7 (26.9%) could consume soft solids, and 12 (46.2%) ate a full diet. The improved ability to eat was statistically significant (p cancer. Metronomic combination chemotherapy with 5-fluorouracil and cisplatin provides a rationale for exploring this medical problem in the future.

    Full Text Available Vinorelbine (Navelbine, VRL is commonly used for platinum-resistant ovarian cancer and has been shown to be effective in patients with recurrent primary peritoneal carcinoma. Of VRL’s major side effects, skin rash is uncommon, and, if it does occur, it is usually localized to site of injection. In this case report, a 71-year-old Hispanic female with primary peritoneal carcinoma received single agent VRL as fourth-line regimen, which she tolerated very well except for a skin rash related to VRL. The rash continued to progress throughout 6 cycles of VRL, and follow-up CT/PET scan demonstrated complete metabolic and radiological responses. We, therefore, believe that this rash was linked to VRL administration and correlated with response to therapy. Rash has been recognized as a useful surrogate marker with targeted agents such as cetuximab and erlotinib; to the best of our knowledge, this case report describes the first patient with a possible drug rash and its association with a positive outcome. This case report incites interest in further investigation of similar cases to support this observation, since there is a lack of reports of skin rash with VRL therapy.

    Peritoneal metastasis is life threatening and is the result of an extensive communication between disseminated cancer cells, mesothelial cells and cancer-associated fibroblasts (CAF). CAFs secrete extracellular matrix (ECM) proteins creating a receptive environment for peritoneal implantation. Considering cancer as an ecosystem may provide opportunities to exploit CAFs to create biomimetic traps to deceive and redirect cancer cells. We have designed microparticles (MP) containing a CAF-derived ECM-surface that is intended to compete with natural niches. CAFs were encapsulated in alginate/gelatine beads (500-750 μm in diameter) functionalised with a polyelectrolyte coating (MP[CAF]). The encapsulated CAFs remain viable and metabolically active (≥35 days), when permanently encapsulated. CAF-derived ECM proteins are retained by the non-biodegradable coating. Adhesion experiments mimicking the environment of the peritoneal cavity show the selective capture of floating cancer cells from different tumor origins by MP[CAF] compared to control MP. MP[CAF] are distributed throughout the abdominal cavity without attachment to intestinal organs and without signs of inflammatory reaction. Intraperitoneal delivery of MP[CAF] and sequential removal redirects cancer cell adhesion from the surgical wound to the MP[CAF], delays peritoneal metastasis formation and prolongs animal survival. Our experiments suggest the use of a biomimetic trap based on tumor-environment interactions to delay peritoneal metastasis. PMID:25907048

  10. PEGylated liposome IHL-305 markedly improved the survival of ovarian cancer peritoneal metastasis in mouse

    International Nuclear Information System (INIS)

    Advanced ovarian cancer is characterized by peritoneal metastasis and the accumulation of ascites. Peritoneal metastasis of ovarian cancer is a major cause of the negative treatment outcome, as these metastases are resistant to most chemotherapy regimens. The aim of this study was to clarify aggressive pathology of peritoneal metastasis and examine the therapeutic efficacy of a liposomal agent in the model. A human cancer cell line ES-2 of ovarian clear cell carcinoma, known as a chemotherapy-resistant cancer, was cultured in nonadherent plate to form spheroid and single cell suspension was transplanted into mouse peritoneal cavity. The epidermal growth factor receptor (EGFR) pathways in the cellular aggregates were analyzed both spheroid and ascites. The pharmacokinetics and therapeutic efficacy of CPT-11 (45 mg/kg) and IHL-305 (45 mg/kg), an irinotecan-encapsulated liposome, were examined by intravenous administration. Established peritoneal metastasis model showed an accumulation of ascites. The activation of EGFR and Akt was demonstrated in cellular aggregates both in the spheroid and ascites. In ascites samples, the area under the curve of SN-38, the activated form of CPT-11, was 3.8 times higher from IHL-305-treated mice than from CPT-11-treated mice. IHL-305 prolonged the survival time and decreased the accumulation of ascites and tumor metastasis. The median survival time were 22, 37 and 54 days in the control, CPT-11-treated, and IHL-305-treated mice, respectively. EGFR/Akt pathway contributes to the aggressive progression in ES-2 peritoneal metastasis model and effective delivery into ascites of IHL-305 was thought to useful treatment for ovarian cancer with peritoneal metastasis

    AIM: To establish a more sensitive method for detection of free cancer cells in peritoneal washes from gastric cancer patients during surgery and to evaluate its clinical significance.METHODS: The carcinoembryonic antigen (CEA) mRNA levels in peritoneal washes from 65 cases of gastric cancer were detected by real-time RT-PCR. Peritoneal lavage cytology (PLC) was applied simultaneously to detection of free cancer cells. Negative controls included peritoneal washes from 5 cases of benign gastric disease and blood samples from 5 adult healthy volunteers.RESULTS: There was no CEA mRNA in peritoneal washes from benign gastric disease patients and in blood of adult healthy volunteers. The positive percentage of free cancer cells detected by real-time RT-PCR was 47.7% and only 12.3% by PLC. The positive rate of CEA mRNA was significantly related with serosa invasion between peritoneal metastasis and stage of gastric cancer.CONCLUSION: Real-time RT-PCR is a sensitive and rapid method for the detection of free cancer cells in peritoneal washes. The presence of free cancer cells in peritoneal washes is related to the pathologic stage of gastric cancer.

    Full Text Available Primary peritoneal localisation of hydatic cyst is exceptional, because the first filter is the liver, the second is the lung and disemination is realised by haematogen way. Another particular situation is the breaking of univesicular hydatic cyst with migration of intact proligera and inseminations of Douglas peritoneum. In this last case is a not true primitive peritoneal localisation. We present a case of a 30 years old patient who comes to physician for hypogastric pains, polakiuria, disuria, rectal tenesma and “pencil-like” stools. Physical examination revealed an abdominal tumor in the hipogastrum and extrinsic compression of rectum superior at the rectal tact. An abdominal ultrasound scan showed a large cystic mass in the pelvis and bilateral ureterohidronefrosis. We realized an open intervention and found and resolved a hydatic cyst of Douglas recessus. The optimal approach – laparoscopic - was not possible because of technical conditions and the desire of patient.

  13. Contribution of 18F-fluorodeoxyglucose positron emission tomography in the detection and evaluation of peritoneal metastasis in colorectal cancer

    International Nuclear Information System (INIS)

    Accurate detection of peritoneal metastasis in colorectal cancer remains a diagnostic challenge. The accuracy of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) in the diagnosis of peritoneal recurrence was evaluated, FDG-PET was conducted in 18 patients previously treated for colorectal cancer and suspected recurrence with clinical symptoms, computed tomography (CT), and tumor markers. Final Diagnosis was obtained by histological evaluation (n=14) or clinical follow-up (n=4). FDG-PET sensitivity was 88%, and accuracy in detecting peritoneal recurrence was 78%. For CT scans, sensitivity was 38% and accuracy 44% Six patients were suspected to have peritoneal recurrence based on FDG-PET and 5 were identified pathologically with peritoneal metastasis. Lesions smaller than 30 mm were not detected by CT. FDG-PET detected 15 mm lesions. In conclusion, FDG-PET is an accurate, noninvasive way to detect peritoneal recurrence in colorectal cancer and would play an important role in clinical management. (author)

  15. Eradication of colon cancer cells before tumour formation in the peritoneal cavity of mice treated with intraperitoneal Re-186 radioimmunotherapy

    International Nuclear Information System (INIS)

    A treatment adjuvant to surgical resection of the primary lesion has been proven to be beneficial in improving the prognosis of patients with high risks of peritoneal dissemination of colon cancer. This study was performed to determine the comparative efficacy of intraperitoneal radioimmunotherapy (RIT) using Re-186 or I-131 labeled murine antibodies in the extermination of cancer cells. A murine anti-colorectal IgG1, A7 monoclonal antibody, was radio-labeled either with I-131 (by the chloramine-T method) or Re-186 (by the MAG3 pre-chelated method). A total number of 16 mice were subjected to RIT with Re-186 A7 (N=8) or I-131 A7 (N=8) at equitoxic doses in Balb/c bu/nu mice 10 min after intraperitoneal injection of LS180 human colon cancer cells. A third group of mice were subjected to chemotherapy with 5-fluorouracil at 30 mg/kg for 4 consecutive days following the intraperitoneal injection of the same LS180 human colon cancer cells. There were 19 mice in the control group who were not subjected to any form of therapy. The results revealed that the mean survival of mice in the control (N-19), I-131 A7 RIT (N=8) and Chemotherapy (N=6) groups were 33.8 ± 1.0, 80.1 ± 2.5 and 49.3 ± 5.3 days respectively. The eight mice who were subjected to Re-186 A7 RIT showed much better survival compared to the other groups. Two of the eight mice from this group died at 105 and 111 days following Re-186 A7 RIT. Other six mice were sacrificed at 172 days, and autopsy revealed no macroscopic peritoneal tumor growth. Based on this pilot study we concluded that individual tumor cells in the peritoneal cavity would be effectively exterminated by intraperitoneal RIT with Re-186 A7. (author)

  16. The clinical role of imaging in peritoneal carcinomatosis

    International Nuclear Information System (INIS)

    Full text: Intraperitoneal seeding, the so-called peritoneal carcinomatosis (PC) is a common mechanism of spread in advanced intra-abdominal malignancies including ovarian (71%), gastric (17%) and colorectal (10%) cancers. When cancer cells from a growing primary neoplasm reach the peritoneal surface, they are carried out by the peritoneal fluid and disseminated throughout the peritoneal cavity.the location of implants development is governed mostly by peritoneal fluid circulation and by anatomic pathways formed by peritoneal reflections, namely ligaments, mesenteries and omenta. The most common sites where the peritoneal fluid may temporarily arrested facilitating implantation of cancer cells include cul-de-sac, distal small bowel mesentery, right paracolic gutter, posterior sub-hepatic space, greater omentum and subphrenic spaces. MDCT with thin collimation and i.v contrast material supplemented by multiplanar reconstructions is the primary imaging modality for the investigation of peritoneal carcinomatosis. Ascitis, contrast enhanced smooth, nodular, or plaque-like peritoneal thickening, peritoneal nodules, plaques or masses, rounded, ill-defined soft-tissue or cystic mesenteric masses, mesenteric fixation with increased attenuation values and thickening, irregular soft-tissue permeation of omental fat or confluent solid omental masses are the most frequent CT findings of peritoneal carcinomatosis. CT has a sensitivity and specificity between 85-95%, depending on the size, location and applied examination protocol.

  19. Is rectal MRI beneficial for determining the location of rectal cancer with respect to the peritoneal reflection?

    International Nuclear Information System (INIS)

    An objective method for determining the location of the cancer with respect to peritoneal reflection would be helpful to decide the treatment modality for rectal cancer. This study was designed to evaluate the accuracy and usefulness of rectal MRI to determine spatial relations between the peritoneal reflection and rectal cancer and to compare these with operative findings. Patients that underwent a rectal cancer operation after a rectal MRI check between November 2008 and June 2010 were considered for the study. The patients that received preoperative concurrent chemoradiation or trans-anal local excision were excluded. Fifty-four patients constituted the study cohort. By comparing surgical and radiologic findings, the accuracy for predicting tumour location in relation to the peritoneal reflection by rectal MRI in all patients was 90.7%. In terms of tumour location in relation to peritoneal reflection, the accuracy of rectal MRI was 93.5% in patients with a tumour located above the peritoneal reflection, 90.0% in patients with a tumour located on the peritoneal reflection, and 84.6% in patients with a tumour located below the peritoneal reflection (p=0.061). When the cohort was subdivided by gender, body mass index (BMI), operative findings, or tumour size, no significant difference was observed among subgroups. Rectal MRI could be a useful tool for evaluating the relation between rectal cancer and peritoneal reflection especially when tumour size is less than 8cm. Rectal MRI can provide information regarding the location of rectal cancer in relation to the peritoneal reflection for treatment planning purposes

    The peritoneum is a mesothelial lining of the abdominal cavity (parietal) and intraperitoneal viscera (visceral). The cavity contains a small amount of fluid, which circulates from cephalad to caudal to cephalad, influenced by negative pressure under the diaphragm during exhalation, gravity, and bowel peristalsis. Peritoneal reflections and mesenteries divide the cavity into various compartments (supramesocolic, inframesocolic, and pelvis). These reflections support the peritoneal organs and provide vascular and nervous connections while within the cavity they influence pathway of intraperitoneal fluid circulation. Capillary force over convex surfaces influence stasis of fluid and promotes peritoneal seeding; thus, there are numerous areas in which peritoneal masses are seen more commonly. These areas include the undersurface of the diaphragm (negative pressure and capillary force), the omentum (bathed in fluid), the right lower quadrant (oblique course from left superior to right inferior of the small bowel mesentery), the left lower quadrant (transverse course of the sigmoid), and the pelvis (gravity). Peritoneal carcinomatosis may be either primary (mesothelioma) or metastatic. The mode of spread is by direct invasion, lymphatic permeation, peritoneal seeding or hematogenous. The imaging patterns include fibronodular stranding, nodules, plaques, and masses. Mesenteric thickening may produce pleated or stellate patterns. Spiral CT is the most useful modality in diagnosis and follow-up of peritoneal tumors. (orig.)

  4. Oral administration of FAK inhibitor TAE226 inhibits the progression of peritoneal dissemination of colorectal cancer

    International Nuclear Information System (INIS)

    Highlights: ► A novel FAK inhibitor TAE226 suppressed FAK activity in HCT116 colon cancer cells. ► TAE226 suppressed proliferation and migration, with a modest effect on adhesion. ► Silencing of FAK by siRNA made no obvious difference on cancer cell attachment. ► TAE226 treatment suppressed the progression of peritoneal dissemination. ► Oral administration of TAE226 prolonged the survival of tumor-bearing mice. -- Abstract: Peritoneal dissemination is one of the most terrible types of colorectal cancer progression. Focal adhesion kinase (FAK) plays a crucial role in the biological processes of cancer, such as cell attachment, migration, proliferation and survival, all of which are essential for the progression of peritoneal dissemination. Since we and other groups have reported that the inhibition of FAK activity exhibited a potent anticancer effect in several cancer models, we hypothesized that TAE226, a novel ATP-competitive tyrosine kinase inhibitor designed to target FAK, can prevent the occurrence and progression of peritoneal dissemination. In vitro, TAE226 greatly inhibited the proliferation and migration of HCT116 colon cancer cells, while their adhesion on the matrix surface was minimally inhibited when FAK activity and expression was suppressed by TAE226 and siRNA. In vivo, when HCT116 cells were intraperitoneally inoculated in mice, the cells could attach to the peritoneum and begin to grow within 24 h regardless of the pretreatment of cells with TAE226 or FAK-siRNA, suggesting that FAK is not essential, at least for the initial integrin-matrix contact. Interestingly, the treatment of mice before and after inoculation significantly suppressed cell attachment to the peritoneum. Furthermore, oral administration of TAE226 greatly reduced the size of disseminated tumors and prolonged survival in tumor-bearing mice. Taken together, a possible strategy for inhibiting peritoneal dissemination by targeting FAK with TAE226 appears to be applicable

    Objective:To establish a positive feedback circuit triggered by Reg4 and investigates its signiifcance in peritoneal metastasis of gastric cancer.Methods: Reg4 expression was detected in gastric cancer samples by immunohistochemistry staining. Reg4 overexpressed and knocked down cells were used to investigate its biological function. Activation of EGFR pathway and promotion of Reg4 were evaluated upon EGFR ligand stimulation. Mass spectrometry was performed to identify Reg4 receptor. ADAM phosphorylation and EGFR ligand shedding was detected after upstream manipulation. Possible downstream effectors were investigated by PCR array.Results:Expression of Reg4 was higher in gastric cancer tissues. Reg4 enhanced prometastatic abilities of gastric cancer cells. EGFR ligand was able to induce Reg4 expression through sequential EGFR pathway activation. Reg4 receptor was identified by mass spectrometry. ADAM phosphorylation and EGFR ligand shedding were enhanced after Reg4 overexpression. PCR array showed several promising downstream effectors.Conclusion:Reg4 is able to trigger a positive feedback regulatory circuit that promotes peritoneal metastasis of gastric cancer.

  11. Free cancer cell detection in peritoneal cavity in gastric cancer patients by RT-PCR for CEA

    International Nuclear Information System (INIS)

    Authors applied RT-PCR assay to detecting CEA expressing free cancer cells in peritoneal cavity of 114 gastric cancer patients to find an indication for prophylactic treatment to prevent peritoneal recurrence. Sixty-three of 114 cases were positive for RT-PCR, of which 16 cases were positive for cytologic examination and 47 cases were negative. Forty-nine of 51 cases who were negative for RT-PCR were negative for cytologic examination. Positivity for RT-PCR according to the depth of invasion were as follows : two (28.6 %) of seven cases whose cancer invaded mucosal or submucosal layer were positive. Ten (45.5 %) of 22 cases whose cancer invaded muscular or subserosal layer were positive. Forty-one (57.7 %) of 71 serosa involved cases were positive. Eleven (78.6 %) of cases who had grossly perioneal seedings were positive (p=0.026). However, all of 7 EGC cases, 19 of 22 cases whose cancer invaded to muscle layer or to subserosa were negative for cytologic examination, and eight of 13 cases who had had peritoneal seedings were positive. Positivity for RT-PCR according to cell differentiation were as follows: forty-two (61.8 %) of 68 cases who cancer were poorly differentiated type were positive. (p=0.163) Serum level of CEA of RT-PCR positive group and that of negative group were not statistically different. It was revealed that RT-PCR was more sensitive than cytologic examination in detecting free tumor cells, especially in pm, ss and serosa positive cancers, so if further study with more cases and longer follow-up is performed, its role as prognostic factor and an indication of prophylactic therapy will be clarified.

  16. Peritoneal mesothelioma

    International Nuclear Information System (INIS)

    The definitive diagnosis of peritoneal mesothelioma and its differentiation from metastatic peritoneal carcinomatosis may be difficult because of the clinical, macroscopic, and microscopic variability of the tumor. To this purpose, a combination of criteria, including the clinical picture, the gross pathologic findings, the exclusion of other primary neoplasms, and the microscopic findings, must be taken into consideration. Conventionally, these criteria may be established only after surgical exploration and extensive sampling. Experience with patients with peritoneal mesothelioma and metastatic peritoneal carcinomatosis, as well as a review of the recent imaging literature, shows excellent correlation between computed tomography or ultrasound and the operative or autopsy findings. These imaging modalities showed soft-tissue masses or nodules; thickened omentum (omental cake), peritoneum, mesentery, and bowel wall; pleural plaques; and usually disproportionally small, if any, ascites. The latter two observations may be useful in differentiating mesothelioma from carcinomatosis macroscopically. Furthermore, fine-needle aspiration biopsy, after performing wide sampling of the tumors in different locations under ultrasonic or computed tomographic guidance, produced diagnostic cytologic specimens. Thus, the need for exploratory surgery may be alleviated, and the diagnosis of peritoneal mesothelioma may be made prospectively and relatively noninvasively with the use of computed tomography or ultrasound and fine-needle aspiration biopsy. Since epidemiologic studies predict increasing incidence of this neoplasm, especially among asbestos workers, it is suggested that these techniques be seriously considered as screening methods for high-risk populations.67 references

    Full Text Available Peritoneal tuberculosis (TB is an extrapulmonary form of presentation of tuberculosis. HIV infection is a primary risk factor for this condition. Diagnosis requires microbiological or histopathological confirmation in addition to supporting radiological imaging studies. Abdominal ultrasonography and CT are useful to obtain a radiographic diagnosis, with typical findings including diffuse peritoneal thickening, presence of ascites in varying volumes, adenopathies, and caseating nodes. We report 2 cases of patients with ascites and nodular peritoneal thickening on diagnostic images, as well as high CA-125 levels in laboratory tests. In both patients, a diagnosis of peritoneal tuberculosis was reached following a US-guided peritoneal biopsy.

    Models based on the multistage theory of carcinogenesis predict that the rate of mesothelioma increases monotonically as a function of time since first exposure (TSFE) to asbestos. Predictions of long-term mortality (TSFE >or= 40 years) are, however, still untested, because of the limited follow-up of most epidemiological studies. Some authors have suggested that the increase in mesothelioma rate with TSFE might be attenuated by clearance of asbestos from the lungs. We estimated mortality time trends from pleural and peritoneal cancer in a cohort of 3,443 asbestos-cement workers, followed for more than 50 years. The functional relation between mesothelioma rate and TSFE was evaluated with various regression models. The role of asbestos clearance was explored using the traditional mesothelioma multistage model, generalized to include a term representing elimination over time. We observed 139 deaths from pleural and 56 from peritoneal cancer during the period 1950-2003. The rate of pleural cancer increased during the first 40 years of TSFE and reached a plateau thereafter. In contrast, the rate of peritoneal cancer increased monotonically with TSFE. The model allowing for asbestos elimination fitted the data better than the traditional model for pleural (p = 0.02) but not for peritoneal cancer (p = 0.22). The risk for pleural cancer, rather than showing an indefinite increase, might reach a plateau when a sufficiently long time has elapsed since exposure. The different trends for pleural and peritoneal cancer might be related to clearance of the asbestos from the workers' lungs. PMID:18528868

    Full Text Available Background: Incidence of multiple primary cancers though uncommon, is being frequently reported now-a-days owing to better diagnostic techniques, the prolonged life span and the increased incidence of long-term survival of cancer patients. Materials and Methods: This is a retrospective study. Cases of multiple malignancies diagnosed histopathologically were retrieved from the archives of department of surgical oncology. Clinical data were obtained from the medical records. They were categorized as synchronous malignancies if the interval between them was less or equal to 6 months and metachronous, if the interval was more than 6 months. Results: A total of 13 cases were encountered in the 5 year study period. Out of them two were in the metachronous category and the rest were synchronous as the 2nd malignancy was detected mostly during clinical evaluation of the patients for the primary malignancy. There was female predominance with age range being 43-68 years. Majority of the cases were in the 7th decade. The most common organ involved was breast, followed by cervix. Apart from bilateral breast malignancies, there were combinations like breast with uterine endometrial carcinoma, cervical carcinoma and even papillary thyroid carcinoma. Conclusion: Detection of multiple primary malignancies is becoming increasingly common in day-to-day practice. Greater awareness of this is required among both cancer patients and their treating clinicians.

  4. Intraperitoneal radioimmunotherapy in treating peritoneal carcinomatosis of colon cancer in mice compared with systemic radioimmunotherapy

    International Nuclear Information System (INIS)

    Peritoneal spread is one of major causes of mortality in colorectal cancer patients. In the current investigation, the efficacy of radio-immunotherapy (RIT) with intraperitoneal (i.p.) administration of an anti-colorectal cancer IgG1, 131I-A7, was compared to that with intravenous (i.v.) administration in BALB/c female mice bearing peritoneal nodules of LS180 human colon cancer cells, at the same toxicity level. Distribution of either i.p. or i.v. administered 131I-A7 and i.p. administered irrelevant 131I -HPMS-1 was assessed. Based on the results of toxicity determination at increments of 2 MBq and estimated dosimetry, an i.p. dose of 11 MBq and an i.v. dose of 9 MBq were chosen for treatment. Mice were monitored for long-term survival: untreated mice (n=11), mice undergoing i.p. RIT with 131I-A7 (n=11), mice undergoing i.v. RIT with 131I-A7 (n=11) and mice undergoing non-specific i.p. RIT with 131I-HPMS-1 (n=5). Intraperitoneal injection of 131I-A7 produced faster and greater tumor accumulation than i.v. injection: 34.2±16.5% of the injected dose per g (% ID/g) and 11.1±3.6% ID/g at 2 h, respectively (P131I-HPMS-1 did not show specific accumulation. Non-specific RIT with 131I-HPMS-1 (mean survival, 26.0±2.5 days) did not affect the survival as compared to no treatment (26.7±1.9 days). Intravenous RIT with 131I-A7 prolonged the survival of mice to 32.8±1.8 days (P131I-A7 improved the survival more significantly and attained cure in 2 of 11 mice (P<0.05 vs. i.v. RIT). In conclusion, i.p. RIT is more beneficial in treating peritoneal carcinomatosis of colon cancer than i.v. RIT in a murine model. (author)

  6. Exosomal miRNAs from Peritoneum Lavage Fluid as Potential Prognostic Biomarkers of Peritoneal Metastasis in Gastric Cancer.

    Directory of Open Access Journals (Sweden)

    Motohiko Tokuhisa

    Full Text Available Peritoneal metastasis is the most frequent type of recurrence in patients with gastric cancer (GC and is associated with poor prognosis. Peritoneal lavage cytology, used to evaluate the risk of peritoneal metastasis, has low sensitivity. Here, we assessed the diagnostic potential of exosomal miRNA profiles in peritoneal fluid for the prediction of peritoneal dissemination in GC. Total RNA was extracted from exosomes isolated from six gastric malignant ascites (MA samples, 24 peritoneal lavage fluid (PLF samples, and culture supernatants (CM of two human gastric carcinoma cell lines that differ in their potential for peritoneal metastasis. Expression of exosomal miRNAs was evaluated with Agilent Human miRNA microarrays and quantitative reverse transcription polymerase chain reaction (qRT-PCR. The microarray analysis indicated a low variability in the number and signal intensity of miRNAs detected among the samples. In the six MA fluids, miR-21 showed the highest signal intensity. We identified five miRNAs (miR-1225-5p, miR-320c, miR-1202, miR-1207-5p, and miR-4270 with high expression in MA samples, the PLF of serosa-invasive GC, and the CM of a highly metastatic GC cell line; these candidate miRNA species appear to be related to peritoneal dissemination. Differential expression of miR-21, miR-320c, and miR-1225-5p was validated in the PLF of serosa-invasive and non-invasive GC by qRT-PCR and miR-21 and miR-1225-5p were confirmed to be associated with serosal invasion in GC. PLF can be used to profile the expression of exosomal miRNAs. Our findings suggest that miR-21 and miR-1225-5p may serve as biomarkers of peritoneal recurrence after curative GC resection, thus providing a novel approach to early diagnosis of peritoneal dissemination of GC.

    The effect of chemotherapy on peritoneal carcinomatosis (PC) of gastric cancer remains unclear. Recently, the intraperitoneal (IP) administration of taxanes [e.g., paclitaxel (PTX) and docetaxel (DOC)] during the perioperative period has shown promising results. Herein, we summarized the rationale and methodology for using IP chemotherapy with taxanes and reviewed the clinical results. IP administered taxanes remain in the IP space at an extremely high concentration for 48-72 h. The drug directly infiltrates peritoneal metastatic nodules from the surface and then produces antitumor effects, making it ideal for IP chemotherapy. There are two types of perioperative IP chemotherapy with taxanes: neoadjuvant intraperitoneal and systemic chemotherapy and sequential perioperative intraperitoneal chemotherapy (SPIC). In SPIC, patients receive neoadjuvant IP chemotherapy and the same regimen of IP chemotherapy after cytoreductive surgery (CRS) until disease progression. Usually, a taxane dissolved in 500-1000 mL of saline at ordinary temperature is administered through an IP access port on an outpatient basis. According to phase I studies, the recommended doses (RD) are as follows: IP DOC, 45-60 mg/m(2); IP PTX [without intravenous (IV) PTX], 80 mg/m(2); and IP PTX (with IV PTX), 20 mg/m(2). Phase II studies have reported a median survival time of 14.4-24.6 mo with a 1-year overall survival of 67%-78%. A phase III study comparing S-1 in combination with IP and IV PTX to S-1 with IV cisplatin started in 2011. The prognosis of patients who underwent CRS was better than that of those who did not; however, this was partly due to selection bias. Although several phase II studies have shown promising results, a randomized controlled study is needed to validate the effectiveness of IP chemotherapy with taxanes for PC of gastric cancer.

    Purpose This study was conducted to investigate the incidence and survival outcomes of second primary cancers after the diagnosis of cervical cancer. Materials and Methods Data from the Korea Central Cancer Registry between 1993 and 2010 were reviewed and analyzed. Standardized incidence ratios (SIRs) of second primary cancers among women with cervical cancer were analyzed. Kaplan-Meier survival curves were constructed for cervical cancer patients with or without a second primary cancer. Results Among 72,805 women with cervical cancer, 2,678 (3.68%) developed a second primary cancer within a mean follow-up period of 7.34 years. The overall SIR for a second cancer was 1.08 (95% confidence interval, 1.04 to 1.12). The most frequent sites of second primary cancers were the vagina, bone and joints, vulva, anus, bladder, lung and bronchus, corpus uteri, and esophagus. However, the incidence rates of four second primary cancers (breast, rectum, liver, and brain) were decreased. The 5-year and 10-year overall survival rates were 78.3% and 72.7% in all women with cervical cancer, and for women with a second primary cancer, these rates were 83.2% and 65.5% from the onset of cervical cancer and 54.9% and 46.7% from the onset of the second primary cancer, respectively. Conclusion The incidence rates of second primary cancers were increased in women with cervical cancer compared to the general population, with the exception of four decreasing cancers. The 10-year overall survival rates were decreased in cervical cancer patients with a second primary cancer. PMID:26194366

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

    The objective of this study was to evaluate the role of the fimbriated end and nonfimbriated epithelium of fallopian tubes with regard to p53 signature, tubal intraepithelial lesions in transition (TILT), and serous tubal in-situ carcinoma (STIC) in cases of different kinds of serous pelvic cancer. This study immunohistochemically evaluated (by Ki-67 and p53 staining) the presence of p53 signature, TILT lesions, and STIC in 14 consecutive cases of prophylactic salpingo-oophorectomy in women with BRCA-1/2 mutation (bilateral salpingo-oophorectomy), 11 cases of macroscopically inconspicuous adnexae of patients with primary contralateral tubal cancer (TC), 9 cases of primary peritoneal cancer (PPC), and 10 cases of serous ovarian borderline tumors, evaluating the fallopian tubes (using the Sectioning and Extensively Examining the FIMbria protocol), ovarian surface epithelium, and ovarian cortical inclusion cysts. The frequencies of p53 signature, TILT, and STIC were 35.7%, 7.1%, and 0% in cases of prophylactic surgery, 18.2%, 9.1%, and 18.2% in TC, and 11.1%, 0%, and 33.3% in PPC. These precursor lesions were missed during the initial routine screening and were found in the fimbriated end of the fallopian tubes in 94%. In 1 case of PPC, staining for p53 was negative in STIC. The studied adnexal tissue of serous ovarian borderline tumor and ovarian cortical inclusion cysts of all cases showed no alterations according to p53 signature, TILT, or STIC. STIC and p53 signature as precursor lesions of pelvic serous cancer were seen in macroscopically inconspicuous contralateral fallopian tubes in unilateral TC, in patients with elective bilateral salpingo-oophorectomy, and in patients affected by PPC. Therefore, we propose the complete processing of adnexal tissue and the use of step sectioning to establish the correct diagnosis. Immunohistochemistry for p53 and ki-67 may aid in the diagnosis, but is not necessary for routine investigation. PMID:21804388

    A new form of dosage (MMC-CH) was composed of activated carbon particles adsorbing mitomycin C. Intraperitoneal administration of MMC-CH was tested clinically for prophylactic and therapeutic effects on peritoneal carcinomatosis of gastric cancer. The criteria of MMC-CH's administration were equal or less than 70 years old, more than 40 kg in body weight, no disfunction of liver and kidney, no particular findings in electrocardiography, S2 or S3 in the grade of serosal invasion, P0, P1, P2 or P3 in the grade of peritoneal dissemination, according to the General Rules for the Gastric Cancer Study in Surgery and Pathology by the Japanese Research Society for Gastric Cancer. MMC-CH was given to 44 patients undergoing gastrectomy for gastric cancer in our department from 1985 to 1988. The 44 patients were composed of 12 patients with P0 findings (P0 patients), 8 patients with P1 findings (P1 patients), 12 patients with P2 findings (P2 patients), and 12 patients with P3 findings (P3 patients). MMC-CH at 50 mg/person in terms of mitomycin C was administered intraperitoneally before the operation wound was closed. Fifty-seven patients in our department from 1983 to 1987 for whom the same criteria were applicable and did not receive MMC-CH therapy, served as the control group. The 57 patients were composed of 23 P0 patients, 21 P1 patients, 10 P2 patients, and 3 P3 patients. There was statistically with chi 2 test no significant difference of age, sex, depth of infiltration macroscopically and microscopically defined progression of lymph-nodal metastases between the MMC-CH group and the control group. Survival rate was calculated with Kaplan-Meier's method in the overall patients in each of the MMC-CH group or the control group. The overall survival rate in the MMC-CH group was statistically significantly (p less than 0.01-0.05) higher from day 460 to day 552 and from day 736 to day 800 than that in the control group. Next, the patients were classified into two subgroups

    Peritoneal metastasis (PM) is a poor prognostic factor in patients with gastric cancer. The aim of this study was to evaluate the efficacy and safety of hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with advanced gastric cancer with PM by retrospective analysis. A total of 54 gastric cancer patients with positive ascitic fluid cytology were included in this study: 23 patients were treated with systemic chemotherapy combined with HIPEC (HIPEC+ group) and 31 received systemic chemotherapy alone (HIPEC- group). The patients were divided into 4 categories according to the changes of ascites, namely disappear, decrease, stable and increase. The disappear + decrease rate in the HIPEC+ group was 82.60%, which was statistically significantly superior to that of the HIPEC- group (54.80%). The disappear + decrease + stable rate was 95.70% in the HIPEC+ group and 74.20% in the HIPEC- group, but the difference was not statistically significant. In 33 patients with complete survival data, including 12 from the HIPEC+ and 21 from the HIPEC- group, the median progression-free survival was 164 and 129 days, respectively, and the median overall survival (OS) was 494 and 223 days, respectively. In patients with ascites disappear/decrease/stable, the OS appeared to be better compared with that in patients with ascites increase, but the difference was not statistically significant. Further analysis revealed that patients with controlled disease (complete response + partial response + stable disease) may have a better OS compared with patients with progressive disease, with a statistically significant difference. The toxicities were well tolerated in both groups. Therefore, HIPEC was found to improve survival in advanced gastric cancer patients with PM, but the difference was not statistically significant, which may be attributed to the small number of cases. Further studies with larger samples are required to confirm our data.

    A major diagnostic challenge to the evaluation of an incomplete intestinal obstruction is to distinguish between infectious and malignant etiologies. We present a case of an elderly woman complaining of abdominal pain accompanied with nausea and vomiting, and failure to pass gas or stools. Anti-tuberculosis drugs were used to relieve her abdominal pain, and a needle biopsy of the peritoneal cavity showed evidence of primary papillary serous carcinoma of the peritoneum (PSCP). This is a rare description of tuberculosis in the setting of PSCP. This report illustrates the potential complex nature of malignancies, and emphasizes the need to consider coexistence of malignancy and infection in patients, especially in those with risk factors for malignancy who fail with antibiotic therapy.

  16. Factors associated with peritoneal metastasis in non-serosa-invasive gastric cancer: a retrospective study of a prospectively-collected database

    International Nuclear Information System (INIS)

    Peritoneal dissemination is the most common type of recurrence in advanced gastric cancer. The main mechanism is thought to be via the exfoliation of free cancer cells (FCCs) from tumor in the gastric serosa. The frequency of recurrence thus increases once the tumor cells penetrate the serosa. However, this type of recurrence also occurs in patients without serosal invasion, though the mechanisms responsible for have not been fully established. We therefore investigated the factors associated with peritoneal dissemination in patients with non-serosa-invasive gastric cancer. A total of 685 patients with non-serosa-invasive gastric cancer who underwent curative resection with retrieval of more than 15 nodes were selected. The associations between clinicopathological features and peritoneal dissemination were analyzed. Among them, the tumor infiltrating growth pattern (INF) were classified into α, β and γ according to the Japanese Classification of Gastric Carcinoma (JCGC). The overall incidence of peritoneal metastasis was 20% (137/685). Age, Borrmann type, differentiation, INF, nodal status and free cancer cells (FCCs) were correlated with peritoneal dissemination using univariate analysis. However, only INF, Borrmann type and TNM node stage were identified as independent correlated factors with peritoneal metastasis by multivariate analysis when FCCs were excluded, and these were also prognostic factors. Peritoneal dissemination was more common in patients with INFγ, Borrmann III/IV and N3 stage. Among patients without FCCs, nodal involvement or vessel invasion, only INF remained an independent associated factor according to multivariate analysis. Tumor infiltrating growth pattern (INF), together with Borrmann type and TNM node stage, are important factors associated with peritoneal metastasis in non-serosa-invasive gastric cancer

    For prevention and therapy of peritoneal dissemination, a new dosage from (MMC-CH) comprising carbon particles adsorbing mitomycin C was given to 44 patients (the MMC-CH group) undergoing gastrectomy for gastric cancer, of which advancing stage was classified into the category of H0, and S2 or S3, and P0, P1, P2 or P3 according to the General Rules for the Gastric Cancer Study. MMC-CH, principally at 50 mg person in terms of mitomycin C was administered intraperitoneally before the surgical wound was closed. Historical control group was composed of 53 patients not given MMC-CH, who underwent gastrectomy for gastric cancer in the same advancing stage as those of the 44 patients. There was statistically no significant difference of age, sex, depth of infiltration, macroscopically and microscopically defined progression of lymph-nodal metastases, between the MMC-CH group and the historical control group. The survival rate of the overall patients, and each group of the patients with the lesion defined as P0, P1, P2, or P3 was compared with Kaplan-Meier's method between the MMC-CH group and the historical control group. In the MMC-CH group, the survival rates of the overall patients and the patients with P0, P1, or P2 lesion were statistically significantly higher than those in the historical control group. However, the rate of the P3 patients in the MMC-CH group was statistically significantly lower than in the historical control group. PMID:2493221

    We aimed at investigating risk of specific second primary cancers (SPCs) after malignant mesothelioma (MM) and vice versa, which has not been reported. Among survivors of 3672 pleural MM and 895 peritoneal MM, overall 113 and 28 SPCs were recorded, respectively, while reverse analyses included overall 431 pleural and 88 peritoneal MMs after any first cancers. We found a bidirectional association of pleural MM with kidney cancer for overall [for second kidney cancer after pleural MM: standardized incidence ratios (SIRs) = 4.4, 95% confidence intervals (CIs): 2.0-8.3; for second pleural MM after kidney cancer: 2.3 (1.3-3.9)] and for cancer was found only for follow-up ≥1 year [3.9 (1.1-10) and 2.8 (1.3-5.1), respectively]. We found a bidirectional association of pleural MM with kidney cancer for overall and for cancer suggests shared genetic or environmental risk factors. PMID:27260871

    We herein report the immunostimulatory effect of spinach aqueous extract (SAE) on mouse macrophage-like J774.1 cells and mouse primary peritoneal macrophages. SAE significantly enhanced the production of interleukin (IL)-6 and tumor necrosis factor-α by both J774.1 cells and peritoneal macrophages by enhancing the expression levels of these cytokine genes. In addition, the phagocytosis activity of J774.1 cells was facilitated by SAE. Immunoblot analysis revealed that SAE activates mitogen-activated protein kinase and nuclear factor-κB cascades. It was found that SAE activates macrophages through not only TLR4, but also other receptors. The production of IL-6 was significantly enhanced by peritoneal macrophages from SAE-administered BALB/c mice, suggesting that SAE has a potential to stimulate macrophage activity in vivo. Taken together, these data indicate that SAE would be a beneficial functional food with immunostimulatory effects on macrophages. PMID:27095137

    The multistage theory of carcinogenesis assumes rates of mesothelioma increasing monotonically as a function of time since first exposure (TSFE) to asbestos. However, some authors have suggested that the increase in mesothelioma rate with TSFE might be attenuated by clearance of asbestos from the lungs. We estimated mortality time trends from pleural and peritoneal cancer in a cohort of 3443 asbestos-cement workers. The role of asbestos clearance was explored using the traditional mesothelioma multistage model, generalized to include a term representing elimination over time. We observed 139 deaths from pleural and 56 from peritoneal cancer during the period 1950-2003. The rate of pleural cancer increased during the first 40 years of TSFE and reached a plateau thereafter. In contrast, the rate of peritoneal cancer increased monotonically with TSFE. The model allowing for asbestos elimination fitted the data better than the traditional model for pleural (p = 0.02) but not for peritoneal cancer (p = 0.22). The risk for pleural cancer, rather than showing an indefinite increase, might reach a plateau when a sufficiently long time has elapsed since exposure. The different trends for pleural and peritoneal cancer might be related to clearance of the asbestos from the workers' lungs. PMID:18409718

    Identification of novel gastric cancer (GC)-related molecules is necessary to improve management of patients with GC in both diagnostic and therapeutic aspects. The aim of the present study was to determine whether protein arginine methyltransferase 5 (PRMT5) acts as an oncogene in the progression of GC and whether it serves as a novel diagnostic marker and therapeutic target. We conducted global expression profiling of GC cell lines and RNA interference experiments to evaluate the effect of PRMT5 expression on the phenotype of GC cells. We analysed tissues of 179 patients with GC to assess the association of PRMT5 mRNA levels with clinicopathological factors. Differential expression of PRMT5 mRNA by GC cell lines correlated positively with the levels of GEMIN2, STAT3 and TGFB3. PRMT5 knockdown reduced the proliferation, invasion and migration of a GC cell line. PRMT5 mRNA levels were significantly higher in GC tissues than the corresponding adjacent normal tissues and were independent of tumour depth, differentiation and lymph node metastasis. High PRMT5 expression was an independent risk factor of positive peritoneal lavage cytology (odds ratio 3.90, P=0.003) and decreased survival. PRMT5 enhances the malignant phenotype of GC cell lines and its expression in gastric tissues may serve as a biomarker for patient stratification and a potential target of therapy. PMID:27315569

  2. A prospective multicenter phase II study evaluating multimodality treatment of patients with peritoneal carcinomatosis arising from appendiceal and colorectal cancer: the COMBATAC trial

    International Nuclear Information System (INIS)

    Peritoneal carcinomatosis is regarded as a common sign of advanced tumor stage, tumor progression or local recurrence of appendiceal and colorectal cancer and is generally associated with poor prognosis. Although survival of patients with advanced stage CRC has markedly improved over the last 20 years with systemic treatment, comprising combination chemotherapy +/− monoclonal antibodies, the oncological outcome—especially of the subgroup of patients with peritoneal metastases—is still unsatisfactory. In addition to systemic therapy, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are specific treatment options for a selected group of these patients and may provide an additional therapeutic benefit in the framework of an interdisciplinary treatment concept. The COMBATAC trial is a prospective, multicenter, open-label, single-arm, single-stage phase II trial investigating perioperative systemic polychemotherapy including cetuximab in combination with CRS and HIPEC patients with histologically proven wild-type KRAS colorectal or appendiceal adenocarcinoma and synchronous or metachronous peritoneal carcinomatosis. The planned total number of patients to be recruited is 60. The primary endpoint is progression-free survival (PFS). Secondary endpoints include overall survival (OS), perioperative morbidity and treatment-associated toxicity, feasibility of the combined treatment regimen, quality of life (QoL) and histopathological regression after preoperative chemotherapy. The COMBATAC trial is designed to evaluate the feasibility and efficacy of the combined multidisciplinary treatment regimen consisting of perioperative systemic combination chemotherapy plus cetuximab and CRS plus bidirectional HIPEC with intraperitoneal oxaliplatin.

  3. Peritoneal lymphomatosis: case report

    International Nuclear Information System (INIS)

    Peritoneal lymphomatosis is a rare manifestation of high grade lymphomas. Although it is difficult to differentiate peritoneal lymphomatosis from other peritoneal diseases such as peritoneal carcinomatosis and leiomyomatosis clinically and radiologically, it should be included in differential diagnosis because the disease is curable with chemotherapy. Consequently, radiologic diagnosis plays a very important role in the detection of this disease. We experienced two cases of peritoneal lymphomatosis with primary gastrointestinal lymphomas in the distal ileum. The two patients were 25 and 50-year-old males. Abdominal CT, ultrasound and barium study were performed on both patients. Both patients had non-Hodgkin's lymphoma confirmed with open or sonographically guided biopsies. Although radiologic appearances overlapped, characteristic findings of long-segmental circumscribed annular mass, aneurysmal luminal dilatation, small to moderate amount of ascites without septation or loculation, diffuse involvement of mesentery, omentum and peritoneum, and enlarged lymph nodes were helpful in narrowing the range of possible diagnoses

    Mesothelioma of the peritoneal cavity after irradiation is rare, and the diagnosis is sometimes difficult to establish. The following case is a report of a mesothelioma occurring 9 years after radiation therapy for carcinoma of the cervix. In this patient, who had a hysterectomy and bilateral oophorectomy 7 years prior to the mesothelioma diagnosis, the histologic, histochemical, and ultrastructural findings were all consistent with a diagnosis of malignant peritoneal mesothelioma. It is believed that this case is one of the first well-documented cases of peritoneal mesothelioma in a female who was treated by pelvic irradiation for another neoplasm

    Full Text Available Introduction: Peritonitis is the most important and frequent infectious complication of peritoneal dialysis. It is the most common cause of failure of the method and inclusion of patients in hemodialysis. Purpose: Τhe purpose of this study is to explore the diagnostic approaches of peritoneal dialysis peritonitis. Methods: Literature review of relevant articles in the database Pubmed as well as the official website of the International Society of Peritoneal Dialysis (ISPD was carried out. The search included articles published during 1996-2013. Results: According to the International Society of Peritoneal Dialysis, peritonitis requires the presence of two of the following criteria: (a cloudy peritoneal fluid, (b symptoms of inflammation of the peritoneum and (c the presence of microorganisms in the peritoneal fluid (> 100 leukocytes / μL of the solution of which most (> 50 % are polymorphnuclear. Some rules of sampling peritoneal fluid for culture and Gram staining are important for the right and immediate treatment of peritonitis: a the first cloudy peritoneal bag is the best sample b sending of the first bag for cultures should be done as early as possible in order to begin the appropriate antibiotic therapy. Gram stain, although in most cases is negative, it is particularly useful for the diagnosis of fungal peritonitis. Conclusions: Patient education, mainly of new Peritoneal Dialysis patients, about the early recognizing of cloudy fluids and exit-site infection, must be the primary concern of a Peritoneal Dialysis Unit. Careful use of antibiotics will reduce the frequency of negative cultures in order not to exceed the limit of 20% of the tests, as recommended by the International Society of Peritoneal Dialysis.

    Full Text Available We present a case report of a 47-year-old woman who was admitted to our University-Hospital following diagnosis of pelvic mass. Abdominal examination revealed a tender, palpable mass on the right iliac region. At the gynecological examination uterus was regular in size. On the left side of the uterus a mass of 9 cm was observed; its surface was irregular and no mobility was found. Abdominal CT and NMR revealed massive ascites, omental cake and increased volume of both ovaries. Patient underwent longitudinal suprombelical-pubic laparotomy. After opening abdominal cavity, a free-fluid sample was taken and the results were positive for malignant cells. Typical neoplastic localizations on both ovaries, Douglas’ peritoneum, rectum, sigmoid colon and omentum were observed. Extemporaneous histological examination diagnosed a peritoneal serous papillary carcinoma. Hysterectomy with salpingo oophorectomy, total omentectomy, appendectomy, pelvic and lumbo-aortic lymphadenectomy was performed. Retroperitoneal approach to remove the whole Douglas’ peritoneum together with the pouch malignant localizations was done. Sigmoid colon and rectum were resected. A latero-terminal anastomosis with stapler was performed. All the visible abdominal maligant lesions were cut out. No transfusion was necessary. The postoperative course was regular and after seven days the patient was discharged. Chemotherapy ended the therapeutic management (six cycles of carboplatin and paclitaxel. After one year the patient is in good health and instrumental investigations (Ultrasounds, TC and NMR are negative for recurrence. Such a case is very interesting for the discrepancy between slight symptoms and severity of the disease, the solution of which was very complex requiring a skillful polyspecialized oncological team.

    AIM: To assess the efficacy of metoclopramide (Met) for prevention of prolonged post-operative ileus in advanced gastric cancer patients undergoing D2 gastrectomy and intra-peritoneal chemotherapy (IPC).METHODS: Thirty-two advanced gastric cancer patients undergoing D2 gastrectomy and IPC were allocated to two groups. Sixteen patients received Met immediately after operation (group A), and 16 did not (group B). Another 16 patients who underwent D2 gastrectomy without IPC were enrolled as the control group (group C). All patients had received epidural pain control. The primary endpoints were time to first post-operative flatus and time until oral feeding with a soft diet without discomfort. Secondary endpoints were early complications during hospitalization.RESULTS: Gender, the type of resection, operating time,blood loss, tumor status and amount of narcotics were connparable in the three groups. However, the group C patients were older than those in groups A and B (67.5±17.7 vs 56.8±13.2, 57.5±11.7 years, P= 0.048). First bowel flatus occurred after 4.35±0.93 d in group A, 4.94±1.37 d in group B, and 4.71±1.22 d in group C (P>0.05). Oral feeding of a soft diet was tolerated 7.21±1.92 d after operation in group A, 10.15±2.17 d in group B, and 7.53±1.35 d in group C(groups A and C vsgroup B, P<0.05). There was no significant difference in respect to the first flatus among the three groups. However, the time of tolerating oral intake with soft food in groups A and C patients was significantly shorter than that in group B patients. Levels of C-reactive protein (CRP) were significantly lower in group C and there was a more prominent and prolonged response in CRP level in patients undergoing IPC. The incidence of post-operative complications was similar in the three groups except for prolonged post-operative ileus. There was no increased risk of anastomotic leakage in patients receiving Met.CONCLUSION: The results suggest that a combination of intravenous

    Full Text Available Peritoneal carcinomatosis (PC is a difficult clinical challenge in colorectal cancer (CRC because conventional treatment modalities could not produce significant survival benefit, which highlights the acute need for new treatment strategies. Our previous case-control study demonstrated the potential survival advantage of cytoreductive surgery (CRS plus hyperthermic intraperitoneal chemotherapy (HIPEC over CRS alone. This phase II study was to further investigate the efficacy and adverse events of CRS+HIPEC for Chinese patients with CRC PC.A total of 60 consecutive CRC PC patients underwent 63 procedures consisting of CRS+HIPEC and postoperative chemotherapy, all by a designated team focusing on this combined treatment modality. All the clinico-pathological information was systematically integrated into a prospective database. The primary end point was disease-specific overall survival (OS, and the secondary end points were perioperative safety profiles.By the most recent database update, the median follow-up was 29.9 (range 3.5-108.9 months. The peritoneal cancer index (PCI ≤20 was in 47.0% of patients, complete cytoreductive surgery (CC0-1 was performed in 53.0% of patients. The median OS was 16.0 (95% confidence interval [CI] 12.2-19.8 months, and the 1-, 2-, 3-, and 5-year survival rates were 70.5%, 34.2%, 22.0% and 22.0%, respectively. Mortality and grades 3 to 5 morbidity rates in postoperative 30 days were 0.0% and 30.2%, respectively. Univariate analysis identified 3 parameters with significant effects on OS: PCI ≤20, CC0-1 and adjuvant chemotherapy over 6 cycles. On multivariate analysis, however, only CC0-1 and adjuvant chemotherapy ≥6 cycles were found to be independent factors for OS benefit.CRS+HIPEC at a specialized treatment center could improve OS for selected CRC PC patients from China, with acceptable perioperative safety.

  13. Risk of second primary cancer following differentiated thyroid cancer

    International Nuclear Information System (INIS)

    Concerns remain over the risk of cancer following differentiated thyroid carcinoma and its causes. Iodine-131 (131I) and external irradiation are known to have potential carcinogenic effects. Thyroid carcinoma is a polygenic disease which may be associated with other malignancies. We investigated the incidence of second cancer and its aetiology in a cohort of 875 patients (146 men, 729 women) with differentiated thyroid carcinoma originating from Basse-Normandie, France. Cancer incidence was compared with that of the general population of the Departement du Calvados matched for age, gender and period. The cumulative proportion of second cancer was estimated using the life-table method. Factors that correlated with the risk of second cancer were studied using the Cox model. After a median follow-up of 8 years, 58 second cancers had been observed. Compared with general population incidence rates, there was an overall increased risk of second cancer in women [standardised incidence ratio (SIR)=1.52; P0.20). Increased risk related to cancers of the genitourinary tract (SIR=3.31; P131I was related to the risk. These data confirm that women with differentiated thyroid carcinoma are at risk of developing a second cancer of the genitourinary tract and kidney. Only age and medical history of primary cancer before thyroid carcinoma are risk factors for second cancer. Common environmental or genetic factors as well as long-term carcinogenic effects of primary cancer therapy should be considered. (orig.)

    Concerns remain over the risk of cancer following differentiated thyroid carcinoma and its causes. Iodine-131 ({sup 131}I) and external irradiation are known to have potential carcinogenic effects. Thyroid carcinoma is a polygenic disease which may be associated with other malignancies. We investigated the incidence of second cancer and its aetiology in a cohort of 875 patients (146 men, 729 women) with differentiated thyroid carcinoma originating from Basse-Normandie, France.

After a median follow-up of 8 years, 58 second cancers had been observed. Compared with general population incidence rates, there was an overall increased risk of second cancer in women [standardised incidence ratio (SIR)=1.52; P<0.01], but not in men (SIR=1.27; P>0.20). Increased risk related to cancers of the genitourinary tract (SIR=3.31; P<0.001), and particularly to cancer of the kidney (SIR=7.02; P<0.01). Multivariate analysis showed that age above 40 years (P<0.01) and a history of previous primary cancer (P<0.001) correlated with risk. In contrast, neither cervical irradiation nor cumulative activity of {sup 131}I was related to the risk. These data confirm that women with differentiated thyroid carcinoma are at risk of developing a second cancer of the genitourinary tract and kidney. Only age and medical history of primary cancer before thyroid carcinoma are risk factors for second cancer. Common environmental or genetic factors as well as long-term carcinogenic effects of primary cancer therapy should be considered. (orig.)

    2016-05-01

    This summary of the American Cancer Society Prostate Cancer Survivorship Care Guidelines targets primary care physicians who coordinate care of prostate cancer survivors with subspecialists. Prostate cancer survivors should undergo prostate-specific antigen screening every six to 12 months and digital rectal examination annually. Surveillance of patients who choose watchful waiting for their prostate cancer should be conducted by a subspecialist. Any hematuria or rectal bleeding must be thoroughly evaluated. Prostate cancer survivors should be screened regularly for urinary incontinence and sexual dysfunction. Patients with predominant urge incontinence symptoms, which can occur after surgical and radiation treatments, may benefit from an anticholinergic agent. If there is difficulty with bladder emptying, a trial of an alpha blocker may be considered. A phosphodiesterase type 5 inhibitor can effectively treat sexual dysfunction following treatment for prostate cancer. Osteoporosis screening should occur before initiation of androgen deprivation therapy, and patients treated with androgen deprivation therapy should be monitored for anemia, metabolic syndrome, and vasomotor symptoms. Healthy lifestyle choices should be encouraged, including weight management, regular physical activity, proper nutrition, and smoking cessation. Primary care physicians should be vigilant for psychosocial distress, including depression, among prostate cancer survivors, as well as the potential impact of this distress on patients' family members and partners.

  17. Efficacy of spiral CT in the evaluation of peritoneal seeding of gastric cancer

    International Nuclear Information System (INIS)

    To determine usefulness of spiral CT in the preoperative evaluation of peritoneal seeding from a gastric carcinoma. From a database of 411 consecutive patients with surgically proven advanced gastric cancinoma obtained over a six-month period, 17 with peritoneal seeding and a control group of 24 without peritoneal seeding underwent spiral CT scanning with 7-8 mm scan thickness and interval during the portal phase. Preoperative CT images were analyzed by two readers who reached a consensus with regard to the presence and location of the ascites, thickening of the parietal peritoneum, and changes in the omentum and mesentery. Ascites was present in 47% (8/17) of patients with peritoneal seeding the right subhepatic space (n=6, 35%) and right paracolic gutter (n=5, 29%)-but not the cul-de-sac (n=2, 12%)-were common sites of fluid collection. Permeative changes in the omentum and mesentery were seen in 18% (3/17) and 12% (2/17) of patients, respectively. Among five controls with false positive results, ascites in the cul-de-sac was present in three (two males and one female, 12%) while omental nodules and a thickened peritoneum were found in two (8%) and one (4%), respectively. In nine controls with false negative results, small disseminated nodules were seen in the mesentery and omentum at surgical field. The sensitivity and specificity of spiral CT were 47% (8/17) and 79% (19/24), respectively. In terms of sensitivity and specificity, spiral CT is not especially accurate in distinguishing peritoneal seeding from gastric carcinoma

  18. 188Re-labelled McAb 3H11 used as preventive for the peritoneal micro-metastasis of gastric cancer

    International Nuclear Information System (INIS)

    In advancing gastric cancer, especially when the serous is invaded, the plantation of cancer cells in peritoneal is common and it affects patients' survival time severely. Based on successfully labelled McAb (monoclonal antibody) 3H11 with 188Re, the authors investigated the effect of RIT (Radio-immuno-Therapy) with 188Re-3H11 on preventing the peritoneal micro-metastasis of gastric cancer cells in nude mice to increase the survival time. After 1 x 106 BGC-823 gastric cancer cells were injected into the peritoneal cavity of each mouse, 45BABL/C nude mice were divided into 9 groups. Each group received different doses of 188Re-3H11 or 188Re-IgG, or saline I.P.16 hours post operation. The injected volume of each mouse was 1.0 mL. The results showed that the survival time depended on the injected dose during 0 to 37 MBq. The survival time was 170 +- 25.3 d after 37 MBq 188Re-3H11 were treated. It was over 5 times more than that for the saline group and about 3 times more than that for 37 MBq 188-Re IgG group (p 188Re-3H11 I.P. is effective and safe for the prevention of intra-peritoneal injected gastric cancer cells from surviving, growing and disseminating in nude mice

  4. A DIFFERENT TECHNIQUE OF PRIMARY INDIRECT INGUINAL HERNIA REPAIR BY INSERTING A SYNTHETIC MESH INTO THE PRE AND RETROPERITONEAL SPACES TO WRAP THE PERITONEAL REFLECTION: PRELIMINARY REPORT

    Professor Aydın Altan

    2010-01-01

    Full Text Available In most methods of indirect inguinal hernia repair, the region of the sac stump remains a potential site of recurrence. A different technique that covers the site of the indirect sac stump is presented. Anterior parietal peritoneum is reflected posteriorly in the inguinal canal. In cases with Gilbert type I-II inguinal hernia, after the indirect sac is removed, the pre and retroperitoneal spaces in this region are dissected. A synthetic mesh is placed into these spaces, lateral to the inferior epigastric vessels. The posterior wall of this type hernia is intact. In cases with Gilbert type III inguinal hernia, either posterior wall repair is accomplished by using one of the tissue approximation techniques after placing a mesh in the region of the sac stump, or the entire peritoneal reflection in the inguinal canal is wrapped with a mesh after dissecting the pre and retroperitoneal spaces. This technique was performed in five patients. Of five patients, mesh was inserted on the region of stump in three (Gilbert I and II and along the entire peritoneal reflection in two (Gilbert III. There were no postoperative complications such as seroma and pain and no recurrence till follow-up. This technique effectively wraps the peritoneal reflection and may prevent recurrences in primary indirect inguinal hernia, but it needs to be performed in a large number of cases for further evaluation.

    The most common properties of oncogenes are cell proliferation and the prevention of apoptosis in malignant cells, which, as a consequence, induce tumor formation and dissemination. However, the effects of oncogenes on the tumor microenvironment (TME) have not yet been examined in detail. The accumulation of ascites accompanied by chronic inflammation and elevated concentrations of VEGF is a hallmark of the progression of ovarian cancer. We herein demonstrated the mechanisms by which oncogenes contribute to modulating the ovarian cancer microenvironment. c-MYC and KRAS were transduced into the mouse ovarian cancer cell line ID8. ID8, ID8-c-MYC, or ID8-KRAS cells were then injected into the peritoneal cavities of C57/BL6 mice and the production of ascites was assessed. ID8-c-MYC and ID8-KRAS both markedly accelerated ovarian cancer progression in vivo, whereas no significant differences were observed in proliferative activity in vitro. ID8-KRAS in particular induced the production of ascites, which accumulated between approximately two to three weeks after the injection, more rapidly than ID8 and ID8-c-MYC (between nine and ten weeks and between six and seven weeks, respectively). VEGF concentrations in ascites significantly increased in c-MYC-induced ovarian cancer, whereas the concentrations of inflammatory cytokines in ascites were significantly high in KRAS-induced ovarian cancer and were accompanied by an increased number of neutrophils in ascites. A cytokine array revealed that KRAS markedly induced the expression of granulocyte macrophage colony-stimulating factor (GM-CSF) in ID8 cells. These results suggest that oncogenes promote cancer progression by modulating the TME in favor of cancer progression. PMID:27483433

    An integrated treatment strategy using peritonectomy procedures plus hyperthermic intraperitoneal chemotherapy (HIPEC) is now a clinical standard of care in selected patients with peritoneal metastases and primary peritoneal tumors. This comprehensive approach can offer many patients, who hitherto had no hope of cure, a good quality of life and survival despite limited morbidity. The increasingly successful results and chance of interfering in the natural history of disease has prompted research to develop for some clinical conditions a therapeutic strategy designed to prevent malignant peritoneal dissemination before it becomes clinically evident and treat it microscopically (tertiary prevention). The main factor governing successful cytoreductive surgery and predicting outcome is the extent of peritoneal spread assessed with the peritoneal cancer index (PCI). In peritoneal metastases from colorectal and gastric cancer the PCI score acquires a specific role acting as the cut-off between patients who can undergo curative surgery or palliation. Long-term results show that the only group enjoying favorable results are patients with limited disease (a statistical minority). By applying to appropriately selected patients with primary malignancies a proactive management strategy including HIPEC we can treat patients with microscopic peritoneal dissemination and therefore at PCI 0. Among treated conditions pseudomyxoma peritonei enjoys the best results. But a major future advance comes from identifying among lesions at major risk of pseudomyxoma. PMID:27065712

  8. Clinical value of 18F-FDG PET/CT in the diagnosis of primary peritoneal papillary serous carcinoma

    International Nuclear Information System (INIS)

    Objective: To explore the diagnostic value of 18F-FDG PET/CT in primary peritoneal papillary serous carcinoma (PPPSC). Methods: Ten postmenopausal female cases of pathologically diagnosed PPPSC from March 2009 to October 2011 were retrospectively reviewed (age range: 61-81 years, mean: (69.4±6.2) years). All cases underwent 18F-FDG PET/CT.The CT characteristics and SUVmax of lesions on PET images were analyzed. Serum CA125 levels were measured before or after PET/CT within one week. The patterns of PPPSC on PET/CT were compared with histopathological results. Linear correlation analysis was used to evaluate the correlation between the CA125 and the maximum SUVmax of lesions presented in parietal peritoneum, greater omentum or mesentery. Results: The PET/CT uptake pattern of the 10 PPPSC cases was described as floccus, multi-nodular or cake-like in greater omentum (SUVmax =6.32±2.87), and as diffuse or localized nodules,or non-uniform strip-like thickening in 9 parietal peritoneum and 8 mesentery cases (SUVmax=5.96±2.14 and 5.70± 1.69, respectively). The most commonly involved sites were pelvic wall of peritoneum and mesentery of small intestine. All 10 cases had different degrees of ascites, mainly intrapelvic and perihepatic. Hypermetabolic ovarian enlargement (all <5 cm) was bilateral in 2 patients and right-sided in 1 patient. Four patients had retroperitoneal lymph node metastasis and others were found with punctate calcifications in metastatic lymph nodes, small pleural effusions, liver metastasis,as well as portal node metastasis. CA125 concentration was elevated in all cases ((51.25±26.40) ×104 U/L), but there was no significant correlation between CA125 and the maximum SUVmax of lesions found in parietal peritoneum, greater omentum or mesentery (r=0.05, P>0.05). Conclusion: 18F-FDG PET/CT could show the positions and metabolic status of PPPSC lesions.It may be an effective imaging modality in the diagnosis and assessment of PPPSC. (authors)

  11. Peritoneal mesothelioma

    International Nuclear Information System (INIS)

    Previous imaging reports of peritoneal mesothelioma have described a variety of radiologic appearances, but have not included its pathologic classification. We retrospectively reviewed 10 cases of peritoneal mesothelioma representing the following histologic categories: 7 epithelial, 2 sarcomatoid, and one biphasic. By imaging, epithelial mesotheliomas demonstrated diffuse thickening of the peritoneum and mesentery and/or multiple small nodules. The sarcomatoid-type appeared as a mass and the biphasic-type had radiologic and gross pathologic features of both sarcomatoid and epithelial types. We conclude that peritoneal mesothelioma presents with a wide spectrum of radiographic appearances and should therefore be included in the differential diagnoses of diffuse as well as localized peritoneal processes.

    Full Text Available Abstract Background A crucial step in the metastatic spread of ovarian cancer (OC is the adhesion and implantation of tumor cells to the peritoneal mesothelium. In order to study this step in the cascade, we derived a pro-metastatic human ovarian carcinoma cell line (MFOC3 from the non-metastatic FOC3 line. Methods Molecular profiling of the isogeneic lines identified differentially expressed genes, and investigation for a role in dissemination for specific factors was achieved by development of a co-culture adhesion assay utilizing monolayers of human mesothelial cells. Results After murine intraperitoneal inoculation, the FOC3 cell line formed no metastases, but the MFOC3 subline formed metastases in > 80% of SCID mice. MFOC3 cells also adhered 2-3 times more avidly to mesothelial monolayers. This adhesion was inhibited by neutralizing antibodies to IL-1β and enhanced by recombinant IL-1β (p in vitro and significantly reduced metastases in vivo. Immunohistochemical analysis of a cohort of 96 ovarian cancer cases showed that negative IL-1β expression was significantly associated with an improved overall survival rate. Conclusions These results suggest that a IL-1β/β1-integrin axis plays a role in ovarian tumor cell adhesion to mesothelia, a crucial step in ovarian cancer dissemination.

In this work, we developed a biodegradable and injectable drug-delivery system by coencapsulation of docetaxel (Doc and LL37 peptide polymeric nanoparticles (Doc+LL37 NPs in a thermosensitive hydrogel system for colorectal peritoneal carcinoma therapy. Firstly, polylactic acid (PLA-Pluronic L35-PLA (PLA-L35-PLA was explored to prepare the biodegradable Doc+LL37 NPs using a water-in-oil-in-water double-emulsion solvent-evaporation method. Then, biodegradable and injectable thermosensitive PLA-L64-PLA hydrogel with lower sol–gel transition temperature at around body temperature was also prepared. Transmission electron microscopy revealed that the Doc+LL37 NPs formed with the PLA-L35-PLA copolymer were spherical. Fourier-transform infrared spectra certified that Doc and LL37 were encapsulated successfully. X-ray diffraction diagrams indicated that Doc was encapsulated amorphously. Intraperitoneal administration of Doc+LL37 NPs–hydrogel significantly suppressed the growth of HCT116 peritoneal carcinomatosis in vivo and prolonged the survival of tumor-bearing mice. Our results suggested that Doc+LL37 NPs–hydrogel may have potential clinical applications. Keywords: intraperitoneal chemotherapy, injectable, nanoparticles, hydrogel

  16. CT findings of peritoneal carcinomatosis

    International Nuclear Information System (INIS)

    CT findings in 137 patients with peritoneal cacinomatosis were reviewed to determine the CT signs of peritoneal malignancy. CT of the 20 liver cirrhosis and 17 tuberculous peritonitis were also reviewed to define the differential point between benign and malignant peritoneal change. The results were as follows. 1. The most common primary malignancy encountered in peritoneal carcinomatosis was stomach Ca.(50.4%), followed by pancreas Ca, hepatoma, colon Ca. and ovarian Ca. 2. Ascites was the most common CT feature of peritoneal malignancy, present in 99 cases (72.3%). The amount of ascites was voluminous, grade III in 70% of cases and showed high density ascites with average 23 Hounsfield units. 3. Greater omentum involvement was noted in 88 patients, peritoneum in 71 patients and mesentery in 65% patients. There was no correlation of the primary malignancy type with the incidence or pattern of the above mentioned site. 4. Bowel wall thickenings were observed in 51 patients, among which transverse colon was most frequently involved. 5. Mean attenuation value of ascites in liver cirrhosis was 10.7 HU, which was much lower than that of peritoneal carcinomatosis. 6. Even though intraperitoneal findings in Tbc. Peritonitis showed tendency of relatively small amount of ascites with more predominant mesenteric change, but, the findings of high density ascites, change of peritoneum and omentum etc. were very similar to those of peritoneal carcinomatosis. Therefore, based on only intraperitoneal change, differential diagnosis between them was difficult. 7. False negatives in CT diagnosis of peritoneal carcinomatosis occurred in 7 cases. There were tiny nodular changes in intraperitoneal cavity without ascites on operative findings

    2011-10-01

    Assessment of the role of vitamins and micronutrients in the primary prevention of prostate cancer has changed dramatically in the past 10 years. Efforts to confirm the efficacy of a single substance have not yet succeeded. Therefore, such recommendations should at present no longer be given. Consideration could even be given to discussing whether additional large-scale interventional studies are expedient in this regard. There is still solid evidence that a well-balanced moderate diet, reduced consumption of milk products, and an Asian or Mediterranean diet are not only beneficial for general good health but can also prevent the development of prostate cancer. This should be the focus of further epidemiological studies. Thus, one can certainly speak of a paradigm shift in the prevention of prostate cancer. In contrast, available data on chemoprevention with 5α-reductase inhibitors is unequivocal: intake of finasteride as well as dutasteride correlates with significantly decreased evidence for prostate cancer. Converting this result into urologic practice remains the topic of extensive controversy. PMID:21927877

  18. Intraoperative radiotherapy in primary rectal cancer

    International Nuclear Information System (INIS)

    According to the results of several studies intraoperative radiotherapy seems to influence local control for primary rectal cancer in UICC-Stage II / III positively, though recommendations in therapy cannot be given as studies of high evidence level do not exist. As IORT is rarely available and makes patient recruitment difficult, prospective randomised trials have not been carried out yet. This emphasizes the importance of non-randomised trials for an evaluation of IORT. A comparison of 21 patients with locally advanced rectal cancer who had been treated with intraoperative radiation therapy and 21 similar cases without an application of IORT could not show any significant improvements in prognosis (recurrences, metastases and disease-specific survival). Nevertheless the employment of intraoperative radiation showed a trend in improvement of local control. This hast been shown by several other studies before. Thus the application of IORT in patients with locally advanced rectal cancer is considered a useful part in multimodal treatment and should further be evaluated in specialized centres. In case-control studies 1:1-matching leads to a good comparability of groups and renders conclusions of high internal validity possible. To gain a sufficient power, this type of trials should however primarily be carried out by centres with a high number of cases.

  19. Primary breast cancer: European radiotherapy trials

    International Nuclear Information System (INIS)

    For many years in Europe, surgically operable breast carcinomas have been treated by conservative treatments. There are two methods of conservative treatment: limited surgery with or without auxiliary dissection followed by irradiation and irradiation as the primary treatment. Depending on the size of the primary tumor and clinical findings in the axillae, patients were referred to either of the two treatment alternatives. Generally, limited surgery and irradiation was performed in patients with early breast carcinomas, while irradiation as the primary treatment was used for more locally advanced cancers. Since 1960, conservative treatments with megavoltage for patients with invasive breast carcinomas have been used more and more frequently. These conservation methods have been used hoping to achieve long-term survival comparable to that obtained by mastectomy and breast preservation with good cosmetic results. This chapter reviews results at 5 and 10 years obtained in Europe by several authors concerning early breast infiltration carcinomas treated by limited surgery or without axillary dissection followed by irradiation

    Intraperitoneal (IP) chemotherapy confers significant survival benefits in cancer patients. However, several problems, including local toxicity and ineffectiveness against bulky tumors, have prohibited it from becoming a standard-of-care. We have developed drug-loaded, tumor-penetrating microparticles (TPM) to address these problems. TPM comprises two components and uses the versatile PLGA or poly(lacticco-glycolic acid) copolymer to provide tumor-selective adherence and pharmacodynamically optimized fractionated dosing to achieve the desired tumor priming (which promotes particle penetration into tumors) plus immediate and sustained antitumor activity. Preclinical studies show that TPM is less toxic and more effective against several IP metastatic tumors with different characteristics (fast vs. slow growing, porous vs. densely packed structures, wide-spread vs. solitary tumors, early vs. late stage, with or without peritoneal carcinomatosis or ascites), compared to the intravenous paclitaxel/Cremophor micellar solution that has been used off-label in previous IP studies. TPM further requires less frequent dosing. These encouraging preclinical results have motivated the follow-up clinical development of TPM. We are working with National Institutes of Health on the IND-enabling studies. PMID:26089090

  3. Inhibition of PRL-3 gene expression in gastric cancer cell line SGC7901 via microRNA suppressed reduces peritoneal metastasis

    International Nuclear Information System (INIS)

    High expression of PRL-3, a protein tyrosine phosphatase, is proved to be associated with lymph node metastasis in gastric carcinoma from previous studies. In this paper, we examined the relationship between PRL-3 expression and peritoneal metastasis in gastric carcinoma. We applied the artificial miRNA (pCMV-PRL3miRNA), which is based on the murine miR-155 sequence, to efficiently silence the target gene expression of PRL-3 in SGC7901 gastric cancer cells at both mRNA and protein levels. Then we observed that, in vitro, pCMV-PRL3miRNA significantly depressed the SGC7901 cell invasion and migration independent of cellular proliferation. In vivo, PRL-3 knockdown effectively suppressed the growth of peritoneal metastases and improved the prognosis in nude mice. Therefore, we concluded that artificial miRNA can depress the expression of PRL-3, and that PRL-3 might be a potential therapeutic target for gastric cancer peritoneal metastasis

  4. Peritoneal dialysis peritonitis: risk factors and effects

    2013-07-01

    Full Text Available Introduction: Peritonitis is the most frequent complication of peritoneal dialysis. It is the main cause of failure of the method and inclusion of patients in hemodialysis Purpose: The purpose of this study is to explore the risk factors of peritoneal dialysis peritonitis as well as the acute and long-term effects of peritonitis on peritoneal membrane function and success of the method. Methods: Literature review of relevant articles in the database Pubmed as well as the official website of the International Society of Peritoneal Dialysis (ISPD was carried out. The search included articles published during the period 1986 -2012.Results: Lack of patient compliance with the peritoneal changes protocol, lack of social support, systemic diseases and connection systems are risk factors of peritonitis. Peritonitis causes transient increase of peritoneum permeability, loss of the ability of the peritoneum for ultrafiltration and, consequently, overhydration. Long-term, recurrent episodes of peritonitis resulting in permanent loss of peritoneum capacity for ultrafiltration even fibrosis that leads to failure of the method. Finally, its effect on the reduction of the residual renal function seems to be remarkable. Conclusions: Peritonitis is the most common infectious complication of peritoneal dialysis and the main cause of morbidity associated with the method. Moreover, it is the major cause of failure of the method and patients accession in hemodialysis. Any attempt to prevent peritonitis passes through the careful patient selection and effective patient education on compliance with the rules of asepsis during peritoneal changes.

  5. Treatment of primary cancer of the penis

    International Nuclear Information System (INIS)

    The results of treatment of 252 cases of cancer of the penis were evaluated. Indications for available methods of treatment with regard to patient's age, stage and size of primary tumor were worked out. Conservative treatment should be given to cases of T1 and T2 tumors, combined treatmemt-T3, and palliative therapy-T4 neoplasms. An experience with cryodestruction of tumor in combination with chemotherapy is discussed. More advantage seems to be offered by application of radiation treatment in such cases. Three- and five-year survival rates for stage 1 tumors were 98.6 and 97.5%, stage 2-84.5 and 83.3% stage 3-26.2 and 24.9% irrespective of the procedure. Not a single patient with stage 4 tumor survived over one year

    A 52-year-old man with Werner Syndrome (WS) was admitted to our hospital for the treatment of skin ulcers on his thighs. Routine chest radiography revealed an abnormal shadow in the left upper lung field. Computed tomography (CT) revealed a poorly demarcated homogeneous mass (diameter, 4 cm) in the S1 + 2 lung area; no pleural effusion was observed. CT-guided percutaneous needle biopsy revealed the presence of an adenocarcinoma. Other imaging studies did not reveal any lymph-node involvement or presence of metastatic lesions. The patient was diagnosed with stage IB adenocarcinoma (T2N0M0), and a left upper lobectomy was successfully carried out; postoperative wound healing was steady and uneventful, with no obvious ulcer formation. Primary lung cancers very rarely develop in patients with WS; non-epithelial tumors are usually observed in such patients. Patients with WS usually develop severe skin problems, such as refractory skin ulcers in the extremities; however, our patient did not develop any skin-related complications after surgery. As the expected lifespan of patients with WS is increasing, we need to pay attention not only to the rare non-epithelial malignancy, but also cancer. Further, the expected short lifespan of patients with WS, as well as the possibility of skin-related problems after surgery, should not be considered while deciding whether to take the option of surgery in the case of malignancy.

    Full Text Available Secondary peritoneal hydatidosis is caused by spontaneous or iatrogenic rupture of hepatic echinococcal cysts. We describe the case of a 65-year-old Tunisian male patient with previous history of liver hydatidosis who presented to our attention with subocclusive status. Imaging revealed a retrovesical hydatid cyst, adherent to the sigmoid colon. The treatment of choice was surgical removal of the cyst and the sigmoid colon. The patient is now being closely followed up.

    INTRODUCTION Cancer is a worldwide problem as it will affect one in three men and one in four women during their lifetime. Colorectal cancer (CRC) is the third most frequent cancer in men, after lung and prostate cancer, and is the second most frequent cancer in women after breast cancer. It is also the third cause of death in men and women separately, and is the second most frequent cause of death by cancer if both genders are considered together. CRC represents approximately 10% of deaths b...

    Five-year survival rates have improved over the past 40 years for nearly all types of cancer, partially thanks to early detection and prevention. Since patients typically present to their primary care physician with initial symptoms, it is vital for primary care physicians to accurately diagnose common cancers and to recognize unusual presentations of highly curable cancers such as Hodgkin lymphoma and testicular cancers, for which the 5-year overall survival rates are greater than 85%. This paper reviews these cancers and provides clinically relevant pearls from an oncologic perspective for physicians who are the first point of contact. PMID:27399864

  13. Primary cancers of extrahepatic biliary passages

    International Nuclear Information System (INIS)

    The records of 22 patients with cancers of extrahepatic biliary passages (EHBP) were analyzed to understand their natural histories and patterns of failure and to evaluate the effectiveness of various treatments. None of the preoperative investigations consistently defined the entire extent of tumor. Percutaneous transhepatic cholangiography (PTHC) was the most helpful (100%) in accurately defining the site of ductal obstruction. Computed tomography was helpful in diagnosing liver metastases in 53% and primary tumor mass in 23% of patients. The most common sites of tumor failure or persistence were: liver (67%), tumor bed (56%), peritoneum (22%), porta hepatis and lymph nodes (17%). The median survival for the entire group was 6.8 months. Surgery plays an important role in managing these tumors and in defining tumor extent for subsequent adjuvant irradiation. Patients receiving radiation doses greater than or equal to 70 TDF had a longer median survival (11 months) than patients receiving less than 70 TDF (4.4 months). All three patients, who were alive and free of disease greater than 1 year, received radiation doses greater than or equal to 70 TDF. From the data, it is difficult to comment on the effectiveness of chemotherapy. The authors have made suggestions regarding radiation volume and doses to various structures. The need for entering these patients into multi-institutional clinical trials is stressed

  17. US findings of bilateral primary breast cancer: Retrospective study

    International Nuclear Information System (INIS)

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index cancer

    The combined treatment concept of cytoreductive surgery (CRS) and Hyperthermic intraperitoneal chemotherapy (HIPEC) has shown to be an efficient therapeutic option for selected patients with primary and secondary peritoneal carcinomatosis (PC). This strategy represents the standard of care for diseases like pseudomyxoma peritonei and peritoneal mesothelioma, and offers the best long-term results for PC from colorectal cancer. Despite these results, skepticism exists regarding this therapeutic approach partly because of its perceived high toxicity. In this article, we review the current evidence on complications that can occur after CRS and HIPEC and the risk factors associated with increased incidence of morbidity and mortality. PMID:27065713

    The clinical characteristics and treatment outcome of patients with primary peritoneal serous papillary carcinoma (PPSC) (n = 22) was compared with stage III-IV papillary serous ovarian carcinoma (PSOC) patients (n = 63). There were no statistically significant differences between the PPSC and PSOC patients with regard to the mean age, menopausal status, parity, ascites fluid volume, proportion of stage IV disease, and the rate of optimal debulking achieved. The median disease-free interval was 15 and 18 months; the median survival was 21 and 26 months; and the 5-year survival was 18 and 24% for the PPSC and PSOC groups, respectively. The median survival time for patients with a residual tumor > or = 2 cm was 20.5 and 24 months, and for residual tumor > or = 2 cm was 46 and 41 months, in PPSC and PSOC patients, respectively. Survival was thus better, in both groups, when residual disease at the end of the operation was PSOC (P PSOC patients. Combining optimal debulking with a platinum-based chemotherapy may offer the patient the most effective treatment. PMID:8774644

    Thanks to continually improving screening programs, diagnostic, and treatment methods, the survival rate in newly diagnosed cancer patients is increasing. With this improvement in survival, attention is now being focused on potential longterm complications such as multiple primary tumors, which represent a leading cause of late nonrelapse mortality. The number of patients who survive cancer dia-gnosis is growing by 2% each year. Multiple primary neoplasms have become the third most common finding in oncology since 1890s, when they were first described. This review aims to summarize recent information regarding the multiple primary neoplasms, elucidate the definition, etiology, association with the primary cancer treatment, genetic and environmental dispositions and finally, it recapitulates new approaches to identification of the risk factors for multiple cancers.

    To histologically assess the preventive efficacy of cimetidine against scald injury on the peritoneo-serosal surface during intraperitoneal hyperthermic chemoperfusion (IHCP) for advanced gastric cancer, a randomized histologic study using cimetidine, a histamine H2-receptor antagonist, was performed for 20 patients with advanced or recurrent gastric cancer and peritoneal metastasis. Cimetidine 50 mg/kg was administered intravenously to 10 patients just prior to the IHCP (cimetidine group), and the remaining 10 patients underwent the IHCP without cimetidine (control group). The background factors and IHCP treatments of these two groups were nearly the same. Although the antitumour efficacy of the IHCP was not histologically different between the two groups, the histological analysis revealed that the peritoneo-serosal surface in the cimetidine group was protected against scald injury, compared with the control group. This finding suggests that pre-IHCP cimetidine is of great benefit for protecting the peritoneo-serosal surface from scald injury due to IHCP. PMID:9483448

  7. Peritoneal and mediastinal highly differentiated follicular carcinoma of ovarian origin

    International Nuclear Information System (INIS)

    A 70-year-old female patient presented to her primary care doctor with persistent elevated alkaline phosphatase of suspected metastatic etiology. Computed tomography demonstrated epicardial and peritoneal nodules. Biopsy of one of the peritoneal nodules revealed thyroid tissue and extraovarian struma ovarii was considered. The patient had a history of remote total abdominal hysterectomy and bilateral salpingo-oophorectomy 31 years prior for endometriosis with no available pathology from that surgery. The patient recalls being told that she had a left ovarian cyst. A thyroid ultrasound was performed that demonstrated multiple nodules without concerning features; however, due to high clinical suspicion, a total thyroidectomy was performed. Upon full histological evaluation a 0.5 cm papillary microcarcinoma was found. Given the rarity of metastatic papillary cancer to the peritoneum and the small size and grade of the tumor, a diagnosis of highly differentiated follicular carcinoma of ovarian origin was favored. The patient was subsequently treated with radioiodine therapy

    International Nuclear Information System (INIS)

    Full text: Peritoneal carcinomatosis can be difficult to diagnose, as CT is insensitive, with peritoneal biopsy and lavage often subject to problems of sampling error. The aim of our study was to evaluate the role of FDG PET in detecting peritoneal carcinomatosis in patients with biopsy-proven metastases from stomach, ovarian and adrenal cancer and mesothelioma. 92 FDG-PET scans of patients with stomach (49), ovarian (14) adrenal cancer (7) and mesothelioma (22) were reviewed. Studies were performed 45 minutes following IV injection of 10 mCi of 18F-FDG. Of this group 15 patients had biopsy-proven findings of peritoneal disease while 14 had PET studies reported as suspicious for peritoneal metastasis. Of the 15 biopsy-positive patients, FDG PET was positive in 7, CT in 6 and either PET or CT in 10 (sensitivities 46.6,40.0 and 66.6% respectively). In a further 4 patients without biopsies, where other imaging studies confirmed peritoneal disease, PET was also positive. 2 distinct abnormal scintigraphic patterns of focal and uniform FDG uptake were identified corresponding to nodular and diffuse peritoneal disease at pathology. Our study demonstrates that FDG PET adds to conventional imaging in the staging of peritoneal carcinomatosis. It is also a useful diagnostic tool when peritoneal biopsy is either unavailable or inappropriate. We have identified 2 distinct scintigraphic patterns which appear to predict the presence of either nodular or diffuse peritoneal pathology.Copyright (2002) The Australian and New Zealand Society of Nuclear Medicine Inc

    Full Text Available Abstract The leading 20th century proponent for primary prevention of environmental cancer was Dr. Lorenzo Tomatis, the former Director of the International Agency for Research on Cancer and founder of the IARC Monographs program. This paper is dedicated to the memory of Dr. Tomatis – eminent scientist, scholar, teacher, humanitarian, and public health champion - and includes many perspectives that he promoted throughout his career, with original quotations from some of his scientific writings on primary prevention of environmental cancer. Any attempt by us to simply summarize his views would only detract from the power and logic of his language. “Cancer still remains a mainly lethal disease. Primary prevention remains the most relevant approach to reduce mortality through a reduction in incidence”1.

  12. Small Bowel Dose Parameters Predicting Grade ≥3 Acute Toxicity in Rectal Cancer Patients Treated With Neoadjuvant Chemoradiation: An Independent Validation Study Comparing Peritoneal Space Versus Small Bowel Loop Contouring Techniques

    International Nuclear Information System (INIS)

    Purpose: To determine whether volumes based on contours of the peritoneal space can be used instead of individual small bowel loops to predict for grade ≥3 acute small bowel toxicity in patients with rectal cancer treated with neoadjuvant chemoradiation therapy. Methods and Materials: A standardized contouring method was developed for the peritoneal space and retrospectively applied to the radiation treatment plans of 67 patients treated with neoadjuvant chemoradiation therapy for rectal cancer. Dose-volume histogram (DVH) data were extracted and analyzed against patient toxicity. Receiver operating characteristic analysis and logistic regression were carried out for both contouring methods. Results: Grade ≥3 small bowel toxicity occurred in 16% (11/67) of patients in the study. A highly significant dose-volume relationship between small bowel irradiation and acute small bowel toxicity was supported by the use of both small bowel loop and peritoneal space contouring techniques. Receiver operating characteristic analysis demonstrated that, for both contouring methods, the greatest sensitivity for predicting toxicity was associated with the volume receiving between 15 and 25 Gy. Conclusion: DVH analysis of peritoneal space volumes accurately predicts grade ≥3 small bowel toxicity in patients with rectal cancer receiving neoadjuvant chemoradiation therapy, suggesting that the contours of the peritoneal space provide a reasonable surrogate for the contours of individual small bowel loops. The study finds that a small bowel V15 less than 275 cc and a peritoneal space V15 less than 830 cc are associated with a less than 10% risk of grade ≥3 acute toxicity

  15. Primary prevention of colorectal cancer: are we closer to reality?

    LENUS (Irish Health Repository)

    Qasim, Asghar

    2012-02-01

    Colorectal cancer is one of the leading causes of morbidity and mortality worldwide. An early detection of colorectal cancer determines therapeutic outcomes, while primary prevention remains a challenge. Our aim was to review the dietary, geographical and genetic factors in the causation and their possible role in the primary prevention of colorectal cancer. Data from experimental and clinical studies and population screening programmes were analysed to determine the factors responsible for causation of colorectal cancer. The role of dietary constituents, including the consumption of fat, red meat, fibre content, alcohol consumption, and other lifestyle issues, including obesity, lack of exercise and geographical variations in cancer prevalence were reviewed. The role of genetic and lifestyle factors in causation of colorectal cancer is evident from the experimental, clinical and population-based studies. Dietary factors, including the consumption of fat, fibre, red meat and alcohol, seem to have a significant influence in this regard. The role of micronutrients, vitamins, calcium may be relevant but remain largely unclear. In conclusion, there is ample evidence favouring the role of various dietary and lifestyle factors in the aetiology of colorectal cancer. Modification of these factors is an attractive option, which is likely to help in the primary prevention and reduced disease burden.

    Full Text Available Abstract Background Antibiotics are preferentially delivered via the peritoneal route to treat peritonitis, a major complication of peritoneal dialysis (PD, so that maximal concentrations are delivered at the site of infection. However, drugs administered intraperitoneally can be absorbed into the systemic circulation. Drugs excreted by the kidneys accumulate in PD patients, increasing the risk of toxicity. The aim of this study is to examine a model of gentamicin pharmacokinetics and to develop an intraperitoneal drug dosing regime that maximises bacterial killing and minimises toxicity. Methods/Design This is an observational pharmacokinetic study of consecutive PD patients presenting to the Royal Brisbane and Women's Hospital with PD peritonitis and who meet the inclusion criteria. Participants will be allocated to either group 1, if anuric as defined by urine output less than 100 ml/day, or group 2: if non-anuric, as defined by urine output more than 100 ml/day. Recruitment will be limited to 15 participants in each group. Gentamicin dosing will be based on the present Royal Brisbane & Women's Hospital guidelines, which reflect the current International Society for Peritoneal Dialysis Peritonitis Treatment Recommendations. The primary endpoint is to describe the pharmacokinetics of gentamicin administered intraperitoneally in PD patients with peritonitis based on serial blood and dialysate drug levels. Discussion The study will develop improved dosing recommendations for intraperitoneally administered gentamicin in PD patients with peritonitis. This will guide clinicians and pharmacists in selecting the most appropriate dosing regime of intraperitoneal gentamicin to treat peritonitis. Trial Registration ACTRN12609000446268

    PURPOSE: Internationally, family physicians (FP) are not routinely involved in young adult cancer (YAC) care. In this short report, we would like to make a compelling argument for primary care involvement. METHODS: Comparative descriptions and literature review. RESULTS: Cancer among YAs is rare...... psychosocial issues the YA cancer patient may present with. The role of the FP in follow-up care seems to be very limited. CONCLUSIONS: YACs in the western world seem to have comparable medical and psychosocial problems. However, the nature of health insurance is such that it impacts differently on the care of...... this group of cancer patients. Primary care features such as patient-centered, integrated, and comprehensive care over extended periods of time bring the FP into the unique position to provide follow-up for YAC. However, this will require integrating patient's perspectives on their care, professional...

    Clinical management of breast cancer is increasingly personalized and based on molecular profiling. Often, primary tumors are used as proxies for systemic disease at the time of recurrence. However, recent studies have revealed substantial discordances between primary tumors and metastases, both with respect to traditional clinical treatment targets and on the genomic and transcriptomic level. With the increasing use of molecularly targeted therapy, discordance of actionable molecular targets between primary tumors and recurrences can result in nonoptimal treatment or unnecessary side effects. The purpose of this review is to illuminate the extent of cancer genome evolution through disease progression and the degree of molecular concordance between primary breast cancers and matched metastases. We present an overview of the most prominent studies investigating the expression of endocrine receptors, transcriptomics, and genome aberrations in primary tumors and metastases. In conclusion, biopsy of metastatic lesions at recurrence of breast cancer is encouraged to provide optimal treatment of the disease. Furthermore, molecular profiling of metastatic tissue provides invaluable mechanistic insight into the biology underlying metastatic progression and has the potential to identify novel, potentially druggable, drivers of progression.

    Breast cancer is the leading type of malignancy and the leading cause of cancer-related deaths in women worldwide. The screening programs and advances in the treatment of patients with breast cancer have led to an increase in overall survival. Cancer registry systems play an important role in providing basic data for research and the monitoring of the cancer status. In this study, the results of the 10-year national cancer registry (NCR) of Iran in breast cancer are reviewed. NCR database records were searched for primary breast cancer records according to ICD-O-3 coding and the cases were reviewed. A total of 52,068 cases were found with the coding of primary breast cancer. Females constituted 97.1% of the cases. Breast cancer was the leading type of cancer in Iranian females, accounting for 24.6% of all cancers. The mean age of the women with breast cancer was 49.6 years (95%CI 49.5-49.6). Most of the cases (95.7%) were registered as having invasive pathologies (behavior code 3). The most common morphology of primary breast cancer was invasive ductal carcinoma (ICD-O 8500/3) followed by invasive lobular carcinoma (ICD-O 8520/3) with relative frequencies of 77.8% and 5.2%, respectively. The average annual crude incidence of primary breast cancer in females was 22.6 (95%CI 22.1-23.1) per 100,000 females, with an age-standardized rate (ASR) of 27.4 (95%CI 22.5-35.9). There were no data on survival, staging or immunohistochemical marker(s) of the breast-cancer-registered cases. The incidence of breast cancer in Iran is lower than in low-middle-income neighboring countries. The NCR data registry of breast cancer is not accurate in monitoring the effect of screening programs or determining the current status of breast cancer in Iran. Screening programs of breast cancer in Iran have failed to enhance the detection of the patients with in situ lesion detection. A quality breast cancer registry and a screening program for breast cancer are both needed. PMID:26070507

The aim of this study was to examine the prevalence of COPD and emphysema at the time of primary lung cancer diagnosis and to examine factors associated with survival.  Materials and methods: Medical records, pulmonary function tests, and computed tomography scans were used to determine the presence of COPD and emphysema in patients diagnosed with primary lung cancer at the University Hospital of North Norway in 2008–2010.  Results: Among the 174 lung cancer patients, 69% had COPD or emphysema (39% with COPD, 59% with emphysema; male:female ratio 101:73. Neither COPD nor emphysema were significantly associated with lung cancer mortality, whereas patients with non-small-cell lung cancer other than adenocarcinoma and squamous cell carcinoma had a risk of lung cancer mortality that was more than four times higher than that of patients with small-cell lung cancer (hazard ratio [HR] 4.19, 95% confidence interval [CI] 1.56–11.25. Females had a lower risk of lung cancer mortality than males (HR 0.63, 95% CI 0.42–0.94, and patients aged ≥75 years had a risk that was twice that of patients aged <75 years (HR 2.48, 95% CI 1.59–3.87. Low partial arterial oxygen pressure (4.0–8.4 kPa increased the risk of lung cancer mortality (HR 2.26, 95% CI 1.29–3.96.

    AIM: To identify the differential proteins associated with colorectal cancer genesis and hepatic metastasis. METHODS: Hydrophobic protein samples were extracted from normal colorectal mucosa, primary cancer lesion and hepatic metastatic foci of colorectal cancer. With twodimensional electrophoresis and image analysis, differentially expressed protein spots were detected, and the proteins were identified by matrix assisted laser desorption/ionization-time of flight-mass spectrometry and peptide mass fingerprint analysis.RESULTS: Significant alterations of the proteins in number and expression levels were discovered in primary cancer and hepatic metastatic foci, the expression of a number of proteins was lost in 25-40 ku, but protein spots was increased in 14-21ku, compared with normal mucosa. Nine differentially expressed protein spots were identified. Three proteins expressed in normal mucosa, but lost in primary cancer and hepatic metastasis, were recognized ascalmodulin, ribonuclease 6 precursor and mannosidase-α.Proapolipoprotein was expressed progressively from normal mucosa to primary cancer and hepatic metastasis. The differentially expressed protein of beta-globin was found in normal mucosa and hepatic metastatic tumor, but lost in primary cancer lesion. Cdc 42, a GTP-binding protein, was identified in hepatic metastasis. The protein spots of C4 from primary cancer, M7 and M9 from hepatic metastasis had less homology with the proteins in database. CONCLUSION: Variations of hydrophobic protein expression in colorectal cancer initiation and hepatic metastasis are significant and can be observed with two-dimensionalelectrophoresis. The expression of calmodulin, ribonuclease6 precursor and mannosidase-α is lost but the expression of proapolipoprotein is enhanced which is associated with colorectal cancer genesis and hepatic metastasis. Cdc 42 and beta-globin are expressed abnormally in hepaticmetastasis. Protein C4, M7 and M9 may be associated withcolorectal

    Primary mucosal leishmaniasis is a rare infectious disease, particularly in immunocompetent patients. We present a 50-year-old patient with a 6-week history of a painful lesion of the left buccal mucosa that mimicked cancer. The exophytic lesion looked invasive, and we took an incisional biopsy specimen to exclude cancer. The diagnosis of leishmaniasis was unexpected, and the patient was successfully treated with amphotericin B for five weeks. After five months the patient had a visceral recurrence. Chronic exophytic and ulcerated mucosal lesions that do not heal within 3-4 weeks should be regarded as the first signs of oral cancer, but primary oral leishmaniasis can easily mimic it.

  12. Risk of second primary lung cancer in women after radiotherapy for breast cancer

    International Nuclear Information System (INIS)

    Background: Several epidemiological studies have reported increased risks of second lung cancers after breast cancer irradiation. In this study we assessed the effects of the delivered radiation dose to the lung and the risk of second primary lung cancer. Methods: We conducted a nested case–control study of second lung cancer in a population based cohort of 23,627 early breast cancer patients treated with post-operative radiotherapy from 1982 to 2007. The cohort included 151 cases diagnosed with second primary lung cancer and 443 controls. Individual dose-reconstructions were performed and the delivered dose to the center of the second lung tumor and the comparable location for the controls were estimated, based on the patient specific radiotherapy charts. Results: The median age at breast cancer diagnosis was 54 years (range 34–74). The median time from breast cancer treatment to second lung cancer diagnosis was 12 years (range 1–26 years). 91% of the cases were categorized as ever smokers vs. 40% among the controls. For patients diagnosed with a second primary lung cancer five or more years after breast cancer treatment the rate of lung cancer increased linearly with 8.5% per Gray (95% confidence interval = 3.1–23.3%; p < 0.001). This rate was enhanced for ever smokers with an excess rate of 17.3% per Gray (95% CI = 4.5–54%; p < 0.005). Conclusions: Second lung cancer after radiotherapy for early breast cancer is associated with the delivered dose to the lung. Although the absolute risk is relative low, the growing number of long-time survivors after breast cancer treatment highlights the need for advances in normal tissue sparing radiation techniques

    Full Text Available With the development of site-specific cancer therapy, identifying the primary origin allows the oncologist to personalise therapy for patients with the cancer of unknown primaries (CUPs. At present, immunohistochemistry (IHC screening is the standard method used to postulate the primary site in CUP. In this retrospective study, we evaluated the prognostic benefit of identifying the primary site in CUP. All 84 patients who presented with suspected CUP to the Royal Stoke University Hospital between 2011 and 2012 were included in our study. Forty-eight percent (40/84 of these patients were unable to undergo necessary investigations to identify primary sites because of poor performance status. IHC screening was able to postulate the primary site in 59% (26/44 of the remaining patients with confirmed CUP. Therefore, the primary site was not identified in a significant proportion of patients with CUP. The median survival of confirmed CUP with probable primary site was 2.0 months (95% confidence interval (CI: 1.2 to 2.9 months, whereas the median survival of confirmed CUP with no probable primary site was 4.1 months (95% CI: 1.5 to 9.7 months. This difference in survival time was statistically significant. In addition, using the Cox regression model, we found that patients with confirmed CUP with primary sites had prognostically unfavourable diseases with a shorter median survival, regardless of the age of disease onset, gender, sites of metastases or number of metastases. One approach to improve the survival would be to start systemic therapy at the earliest possible opportunity rather than waiting for all investigation results, such as IHC.

    International Nuclear Information System (INIS)

    Objective: To evaluate the therapeutic efficacy of three-dimensional conformal radiotherapy (3DCRT) for unresectable primary hepatic cancer (PHC). Methods: 117 patients with locally advanced liver cancer were treated by 3DCRT using 8 MV X-ray. The mean gross target volume (GTV) was 478.5 cm3 (30-2015 cm3). Patients received a total dose of 40.0-57.6 Gy (mean 50.8 Gy), 4-8 Gy per session every other day. Results: Immediately response rates were CR 11.9%; PR 64.2%; NR 18.3%; PD 5.5%, respectively. The CR + PR response rate was 76.1%. The 1-, 2-, 3- year survival rates were 68.6%, 42.0%, 28.8%, respectively. The CR and PR rates of lesions complicated with portal venous cancer embolus (PVCE) were 82.5%, 10.0%, with a response rate (CR + PR) of 92.5%. The 1-, 2-year survival rates of PHC with PVCE were 52.1% and 19.7%. The incidence of radiation-induced hepatitis was 7.3%. The Clild-pugh class and GTV were independent prognostic factors when analyzed by Cox propotional hazards model. Conclusions: It is effective to treat unresectable primary hepatic cancer with three-demensional conformal radiotherapy by improving the local control and the survival. It is also effective for lesions complicated with portal venous cancer embolus. (authors)

    The purpose was to evaluate the clinical results of stereotactic radiotherapy in primary liver tumors and hepatic metastases. Five patients with primary liver cancer and 39 patients with 51 hepatic metastases were treated by stereotactic radiotherapy since 1997. Twenty-eight targets were treated in a 'low-dose'-group with 3x10 Gy (n=27) or 4x7 Gy (n=1) prescribed to the PTV-encl. 65%-isodose. In a 'high-dose'-group patients were treated with 3x12 - 12.5 Gy (n=19; same dose prescription) or 1x26 Gy/PTV-enclosing 80%-isodose (n=9). Median follow-up was 15 months (2-48 months) for primary liver cancer and 15 months (2-85 months) for hepatic metastases. While all primary liver cancers were controlled, nine local failures (3-19 months) of 51 metastases were observed resulting in an actuarial local control rate of 92% after 12 months and 66% after 24 months and later. A borderline significant correlation between dose and local control was observed (p=0.077): the actuarial local control rate after 12 and 24?months was 86% and 58% in the low-dose-group versus 100% and 82% in the high-dose-group. In multivariate analysis high versus low-dose was the only significant factor predicting local control (p=0.0089). Overall survival after 1 and 2 years was 72% and 32% for all patients and was impaired due to systemic progression of disease. No severe acute or late toxicity exceeding RTOG/EORTC-score 2 were observed. Stereotactic irradiation of primary liver cancer and hepatic metastases offers a locally effective treatment without significant complications in patients, who are not amenable for surgery. Patient selection is important, because those with low risk for systemic progression are more likely to benefit from this approach.

    The peritoneal cavity is a complex anatomical structure with multiple attachments and connections. These are better understood with reference to the embryological development of this region. Armed with this knowledge, the diagnosis and assessment of a wide range of common intra-abdominal diseases becomes straightforward. This article will review and simplify the terminology, complex embryological development, and anatomy of the peritoneum, peritoneal attachments, and the reflections forming the peritoneal boundaries. Normal anatomy will be described using schematic diagrams with corresponding computed tomography (CT) and magnetic resonance imaging (MRI) images, including CT peritoneograms. The relevance of intra- and extra-peritoneal anatomy to common pathological processes will be demonstrated

  3. Technique of Peritoneal Catheter Placement under Fluoroscopic Guidance

    International Nuclear Information System (INIS)

    Peritoneal catheters are mainly used for peritoneal dialysis in patients with end-stage renal disease. Other uses of this catheter include intraperitoneal chemotherapy and gene therapy for ovarian cancer and draining of uncontrolled refractory ascites in patients with liver cirrhosis. Traditionally, surgeons place most of these peritoneal catheters either by laparoscopy or open laparotomy. We detail our percutaneous approach to placing peritoneal catheters using fluoroscopic guidance. We emphasize the use of additional ultrasound guidance, including gray scale and color Doppler ultrasound, to determine the safest puncture site and to guide the initial needle puncture in order to avoid bowel perforation and injury to epigastric artery. We present our experience in placing peritoneal catheters using this technique in 95 patients with various indications. Fluoroscopic guided percutaneous placement of peritoneal catheters is a safe, minimally invasive, and effective alternative to open surgical or laparoscopic placement.

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

  5. Cancer Stem Cells in Primary Liver Cancers: Pathological Concepts and Imaging Findings

    International Nuclear Information System (INIS)

    There is accumulating evidence that cancer stem cells (CSCs) play an integral role in the initiation of hepatocarcinogenesis and the maintaining of tumor growth. Liver CSCs derived from hepatic stem/progenitor cells have the potential to differentiate into either hepatocytes or cholangiocytes. Primary liver cancers originating from CSCs constitute a heterogeneous histopathologic spectrum, including hepatocellular carcinoma, combined hepatocellular-cholangiocarcinoma, and intrahepatic cholangiocarcinoma with various radiologic manifestations. In this article, we reviewed the recent concepts of CSCs in the development of primary liver cancers, focusing on their pathological and radiological findings. Awareness of the pathological concepts and imaging findings of primary liver cancers with features of CSCs is critical for accurate diagnosis, prediction of outcome, and appropriate treatment options for patients

    To assess the effects of atomic bomb radiation on the incidence of multiple primary cancers (MPC), we analyzed the association between the incidence of second primary cancers in survivors of the atomic bombing of Nagasaki, and exposure distance. The incidence rate (IR) of a second primary cancer was calculated and stratified by the distance from the hypocenter and age at the time of bombing for the years 1968 through 1999. The IR of the first primary cancer was also calculated and compared wi...

  9. Histological evaluation of AMPK signalling in primary breast cancer

    International Nuclear Information System (INIS)

    AMP-activated protein kinase (AMPK) acts as a cellular fuel gauge that responds to energy stress by suppressing cell growth and biosynthetic processes, thus ensuring that energy-consuming processes proceed only if there are sufficient metabolic resources. Malfunction of the AMPK pathway may allow cancer cells to undergo uncontrolled proliferation irrespective of their molecular energy levels. The aim of this study was to examine the state of AMPK phosphorylation histologically in primary breast cancer in relation to clinical and pathological parameters. Immunohistochemistry was performed using antibodies to phospho-AMPK (pAMPK), phospho-Acetyl Co-A Carboxylase (pACC) an established target for AMPK, HER2, ERα, and Ki67 on Tissue Micro-Array (TMA) slides of two cohorts of 117 and 237 primary breast cancers. The quick score method was used for scoring and patterns of protein expression were compared with clinical and pathological data, including a minimum 5 years follow up. Reduced signal, compared with the strong expression in normal breast epithelium, using a pAMPK antibody was demonstrated in 101/113 (89.4%) and 217/236 (91.9%) of two cohorts of patients. pACC was significantly associated with pAMPK expression (p = 0.007 & p = 0.014 respectively). For both cohorts, reduced pAMPK signal was significantly associated with higher histological grade (p = 0.010 & p = 0.021 respectively) and axillary node metastasis (p = 0.061 & p = 0.039 respectively). No significant association was found between pAMPK and any of HER2, ERα, or Ki67 expression, disease-free survival or overall survival. This study extends in vitro evidence through immunohistochemistry to confirm that AMPK is dysfunctional in primary breast cancer. Reduced signalling via the AMPK pathway, and the inverse relationship with histological grade and axillary node metastasis, suggests that AMPK re-activation could have therapeutic potential in breast cancer

  10. CT images in brain metastases of the primary lung cancer

    International Nuclear Information System (INIS)

    Computed tomography (CT) of the brain was carried out in 366 patients with lung cancer in order to evaluate brain metastases. Suggestive evidences of metastases such as low density or contrast enhancement were observed in 65 cases (18%), although 26% of the metastatic cases revealed no signs or symptoms of neurological disorders. These facts emphasize that brain CT should be conducted in all patients with lung cancer, irrespective of signs and symptoms. A solitary lesion was noted in 37 out of 65 metastatic cases. More than 80% of the metastatic lesions were demonstrated as iso-density on plain CT films and were enhanced by intravenous injection of contrast medium. Although CT images of metastatic lesions reveal certain characteristic appearances according to the histologic type of the primary cancer, perifocal low density and central cavitation were observed independent of histologic type.

    2007-01-01

    In order to investigate the possibility of overexpression of Twist in primary liver cancer (PLC), the Twist expression was detected by using immunohistochemical analysis and RT-PCR assay in 45 patients with PLC. Control tissues were obtained from 9 patients with liver hemangioma. It was found that in 36 (80.0%) out of 45 PLC patients, cancerous regions showed positive cytoplasm and nucleus staining for Twist with a diffuse pattern. In noncancerous adjacent areas and control liver tissues, the expression of Twist was 57.8% and 22.2% respectively. The results of RT-PCR assay re- vealed that the expression of Twist was stronger in the cancerous tissues than that in the noncancer- ous adjacent tissues. It was suggested that the expression of Twist was up-regulated in PLC, which play an important role in the progression of PLC.

  13. The Primary Cilium in Cell Signaling and Cancer

    Energy Technology Data Exchange (ETDEWEB)

    Michaud III, Edward J [ORNL; Yoder, Bradley [University of Alabama, Birmingham

    2006-01-01

    The primary cilium is a microtubule-based antenna-like structure that emanates from the surface of virtually all cells in the mammalian body. It is anchored to the cell by the basal body, which develops from the mother centriole of the centrosome in a manner that is coordinately regulated with the cell cycle. The primary cilium is a sensory organelle that receives both mechanical and chemical signals from other cells and the environment, and transmits these signals to the nucleus to elicit a cellular response. Recent studies revealed that multiple components of the Sonic hedgehog and plateletderived growth factor receptor-A signal transduction pathways localize to the primary cilium, and that loss of the cilium blocks ligand-induced signaling by both pathways. In light of the major role that these pathways play in numerous types of cancer, we anticipate that the emerging discoveries being made about the function of the primary cilium in signaling pathways that are critical for embryonic development and tissue homeostasis in adults will also provide novel insights into the molecular mechanisms of carcinogenesis.

    Patient-tailored treatments for breast cancer are based on histological and immunohistochemical (IHC) subtypes. Magnetic Resonance Imaging (MRI) texture analysis (TA) may be useful in non-invasive lesion subtype classification. Women with newly diagnosed primary breast cancer underwent pre-treatment dynamic contrast-enhanced breast MRI. TA was performed using co-occurrence matrix (COM) features, by creating a model on retrospective training data, then prospectively applying to a test set. Analyses were blinded to breast pathology. Subtype classifications were performed using a cross-validated k-nearest-neighbour (k = 3) technique, with accuracy relative to pathology assessed and receiver operator curve (AUROC) calculated. Mann-Whitney U and Kruskal-Wallis tests were used to assess raw entropy feature values. Histological subtype classifications were similar across training (n = 148 cancers) and test sets (n = 73 lesions) using all COM features (training: 75 %, AUROC = 0.816; test: 72.5 %, AUROC = 0.823). Entropy features were significantly different between lobular and ductal cancers (p < 0.001; Mann-Whitney U). IHC classifications using COM features were also similar for training and test data (training: 57.2 %, AUROC = 0.754; test: 57.0 %, AUROC = 0.750). Hormone receptor positive and negative cancers demonstrated significantly different entropy features. Entropy features alone were unable to create a robust classification model. Textural differences on contrast-enhanced MR images may reflect underlying lesion subtypes, which merits testing against treatment response. (orig.)

    The incidences of both type 1 diabetes (T1D) and T2D are increasing worldwide. T2D is associated with many cancers. However, no data are available on cancer of unknown primary (CUP), a relatively common, fatal cancer for which tobacco smoking is the only known risk factor. At diagnosis, CUP metastases are found in various organs, which has implications for prognosis. We carried out a nationwide study on the association of CUP with T1D and T2D. 32 600 T1D patients and 178 000 T2D patients were identified from the national healthcare registers and these were linked to the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for CUP from 1997 through 2010 using anyone without diabetes as a reference. The SIR of CUP in 421 diabetic patients was 1.71, highest for CUP with liver (2.17) and respiratory system (1.95) metastases. The SIR was 2.91 for T1D, but with a small number of patients, 1.38 for T2D with insulin treatment, and 1.78 for the main group of T2D. CUP with liver and respiratory system metastases increased for each diabetic type; however, for T2D, CUP with gastrointestinal and bone metastases also increased. The results provide the first demonstration that CUP is one of the cancers associated with diabetes, with definite evidence on T2D. CUP has a poor prognosis, which may be even worse when diabetes is the underlying comorbidity. A mechanistic question for future work is to determine whether diabetes promotes primaries that escape detection or their metastatic spread. PMID:26011105

    Full Text Available Peritonitis is an important problem of peritoneal dialysis patients. Although Gram (+ bacteria are more frequent, Gram (- bacteria can rarely be the cause of peritonitis. Yersinia enterocolitica is a Gram (- enteric bacteria that especially causes gastrointestinal infections via contaminated food intake in immunosuppressive situations such as haemochromatosis, desferroxamine therapy or chronic hepatitis. We report a 51-year-old man who had been undergoing SAPD because of chronic renal failure for 2 years. We evaluated his peritoneal fl uid because of symptoms of peritonitis. His peritoneal cellular composition was consistent with peritonitis and after the microbiological culture of the fl uid we determined Yersinia enterocolitica as the pathogenic agent. The peritonitis persisted despite the administration of long term combined antibiotherapy and we removed the peritoneal catheter. In conclusion, Yersinia enterocolitica peritonitis is resistant to conventional antibiotic therapy and an indication for catheter removal.

    2016-09-01

    Breast cancer is the most frequently diagnosed cancer in women. Early detection of breast cancer is known to increase survival rates significantly after diagnosis. This research was carried out to determine the level of breast cancer risk among primary healthcare nurses and their belief in breast cancer screening. In this descriptive research, the data were collected in face-to-face interviews with the participants. The researchers contacted all primary healthcare nurses currently working in the province. The data collection tools included a questionnaire form on sociodemographic characteristics, breast cancer risk assessment form, and Champion's Health Belief Model Scale (CHBMS) for breast cancer screening. In data analysis, descriptive statistics, t test, and analysis of variance (ANOVA) were used. The mean age of nurses was 35 ± 3.6. The mean score for the breast cancer risk assessment form was calculated as 82.9 ± 18.7. The subscale scores for the CHBMS for breast cancer screening were as follows: susceptibility 7.3 ± 1.8, seriousness 19.5 ± 4.1, benefits of breast self-exam 15.5 ± 2.6, barriers to breast self-exam 15.1 ± 2.8, self-efficacy 40.3 ± 7.0, and motivation 19.5 ± 4.1. The risk of breast cancer was found to be low in the study group. The analysis of the subscale scores for the CHBMS for breast cancer screening revealed that nurses had a below-average susceptibility perception, a somewhat lower perception of seriousness, an above-average mean score for perceived benefits, a moderate barrier perception, a relatively high perceived self-efficacy, and motivation above average.

    2016-07-01

    The Unfolded Protein Response (UPR) is an adaptive cellular program used by eukaryotic cells to cope with protein misfolding stress in the Endoplasmic Reticulum (ER). During tumor development, cancer cells are facing intrinsic (oncogene activation) and extrinsic (limiting nutrient or oxygen supply; exposure to chemotherapies) challenges, with which they must cope to survive. Primary brain tumors are relatively rare but deadly and present a significant challenge in the determination of risk factors in the population. These tumors are inherently difficult to cure because of their protected location in the brain. As such surgery, radiation and chemotherapy options carry potentially lasting patient morbidity and incomplete tumor cure. Some of these tumors, such as glioblastoma, were reported to present features of ER stress and to depend on UPR activation to sustain growth, but to date there is no clear general representation of the ER stress status in primary brain tumors. In this review, we describe the key molecular mechanisms controlling the UPR and their implication in cancers. Then we extensively review the literature reporting the status of ER stress in various primary brain tumors and discuss the potential impact of such observation on patient stratification and on the possibility of developing appropriate targeted therapies using the UPR as therapeutic target.

    International Nuclear Information System (INIS)

    Objective: To determine the patterns of peritoneal involvement in patients with abdominopelvic malignancies. Study Design:Retrospective observational study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from May 2004 to May 2012. Methodology: Two hundred and three patients with histopathologically proven abdominopelvic malignancies with peritoneal involvement who underwent contrast-enhanced CT abdomen and pelvis were identified through electronic data base system and were included in this study after ethical committee approval. Peritoneal disease pattern, predominant sites of involvement and associated findings of ascites, lymph nodes and metastasis were assessed. Patients with tuberculosis and lymphoproliferative disorders were excluded. Results: The malignancies showing peritoneal involvement, in decreasing order of frequency, were ovarian cancer (n=118), colorectal cancer (n=45), pancreatic cancer (n=11), gastric cancer (n=7), endometrial cancer (n=6), gallbladder/ challenge-carcinoma and hepatocellular cancer (n=5 each), cervical cancer (n=3), renal cell carcinoma (n=2) and transitional cell urinary bladder cancer (n=1). The most common pattern of peritoneal involvement was mixed in 79 patients (39 percentage), omental caking in 74 patients (37 percentage) and nodular deposits in 50 patients (24 percentage). The most common sites of peritoneal involvement were pelvic peritoneum followed by greater omentum. Conclusion: Peritoneal involvement is the commonest with ovarian and colorectal carcinoma. Mixed pattern of peritoneal disease was most frequently seen in these patients followed by omental caking and nodular peritoneal deposits. (author)

  2. Plain radiologic findings of primary lung cancer by histologic types

    International Nuclear Information System (INIS)

    Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult to interpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases of histologically confirmed primary lung cancer from January 1974 to April 1982 at Seoul National University. The results are as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex radio was 3.8 : 1 and there was no sex difference in Adenocarcinoma. 2. Distribution of histologic types of primary lung cancers as follows; Squamous cell carcinoma 50.6%, Small cell carcinoma 22.5%, Large cell carcinoma 9.3%, Bronchogenic adeno carcinoma 10.5%, Bronchioloalveolar cell carcinoma 1.9%, Adenosquamous carcinoma 0.6%, Carcinoid tumor 0.3%, Adenoid cystic carcinoma 0.3%. 3. Radiologic findings by histologic types are follows; a) Squamous cell carcinoma commonly present as collapse (51.8%), peripheral mass (40.8%), pneumonitis (37.2%), hilar involvement (34.8%), and in single abnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement (78.1%), mediastinal widening or mass (53.4%) and in single abnormality, hilar involvement (58.3%). c) Large cell carcinoma commonly present as hilar involvement (50%), pneumonia (46.7%), collapse (40%), peripheral mass (36.7%) and in single abnormality, large peripheral mass (33.3%). d) Bronchogenic adenocarcinoma commonly present as peripheral mass (44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass (50%). e) Solitary peripheral mass commonly present as lobulation (48%) and spiculated margin (51%), but no specific findings by histologic types. Cavitary formation was most common in Squamous cell carcinoma

    Full Text Available Peritoneal carcinomatosis due to breast cancer is rare and gastrointestinal tract involvement is also unusual. Symptoms are unspecific and can begin many years after the primary tumor. Investigation of carcinomatosis origin is mandatory as breast cancer carcinomatosis can relieve partially or totally with chemo and hormonal therapy. A case of colonic obstruction due to carcinomatosis secondary to breast cancer is reported, emphasizing its diagnostic aspects and treatment.A carcinomatose peritoneal secundária ao câncer de mama é entidade rara e o comprometimento do trato gastrointestinal é pouco frequente. A sintomatologia bastante inespecífica dificulta o diagnóstico e os sintomas podem surgir vários anos após o aparecimento do tumor primário. O diagnóstico da origem da carcinomatose é fundamental, pois quando a doença é secundária à neoplasia de mama, pode ocorrer remissão parcial e até total da doença com quimio e hormonioterapia. Relata-se caso de obstrução colônica devido a carcinomatose peritoneal secundária a neoplasia maligna de mama, com ênfase em seu diagnóstico e tratamento.

  4. Treatment of brain metastases from primary lung cancer

    International Nuclear Information System (INIS)

    Purpose: A retrospective study of patients treated at the Peter MacCallum Cancer Institute for brain metastases from primary carcinoma of the lung is presented. Methods and Materials: The medical records of 416 patients with the diagnosis of primary carcinoma of the lung who presented with, or subsequently developed, brain metastases during the period January 1984 to December 1987 were reviewed. Information on a number of factors of potential prognostic significance (sex, age, histology, performance status and interval between diagnosis of the primary and brain metastases) was collected. Details of surgery, radiation and steroid usage were recorded, and any steroid side effects documented. Survival was calculated from the date of diagnosis of brain metastases. Stepwise regression based on Cox's proportional hazards model was used to determine significant prognostic factors affecting survival. Patients with and without steroid side effects were compared using Yate's corrected chi-square test. Results: The overall estimated median survival was only 3.3 months (95% confidence interval 2.9-3.7 months). Only two factors were found to be associated with a significantly improved survival--surgical intervention and good performance status. After taking these two factors into account, the dose of radiation used (< 30 Gy or ≥ 30 Gy) did not influence survival. There was a 3% incidence of gastric bleeding or perforation in patients taking steroids, with a 40% fatality rate. Predisposing factors to gastric side effects were a prior history of peptic ulcer and/or aspirin or nonsteroidal anti-inflammatory drug consumption. Conclusion: Radiation of brain metastases from primary lung cancer results in modest survival benefit. Radiation dose (< 30 Gy or ≥ 30 Gy) is not a significant determinant of survival. Other treatment modifications, such as concurrent radiation and chemotherapy, should be explored. Steroids should be used with caution as fatal side effects can occur

  5. Nonbreast Second Malignancies After Treatment of Primary Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: To determine the incidence and risk factors for nonbreast second malignancies (NBSMs) in women after treatment for primary breast cancer. Methods and Materials: Between January 1985 and December 1995, a total of 1,084 breast cancer patients were analyzed for NBSMs. Detailed analysis was carried out for age, family history, disease stage, radiation therapy, chemotherapy, hormone therapy, other clinical/pathologic characteristics, and site of NBSMs. The Cox proportional hazard regression model was used to estimate the relative risk of NBSMs. Results: Median follow-up was 12 years. In total, 33 cases of NBSMs were noted in 29 patients. The overall incidence of NBSM was 3%, and the median time for NBSMs was 7 years. The most common NBSMs were gynecologic (22 patients), gastrointestinal (4 patients), head and neck (3 patients), hematologic (2 patients), lung (1 patient), and thyroid (1 patient). The NBSMs rate at 12 years was 2.4% for both mastectomy and radiation therapy groups. In the subset of patients less than 45 years of age at the time of treatment, the NBSMs rate was 0.7% as compared with 4.6% in patients more than 45 years of age (p = 0.001). Statistically significant higher incidences of endometrial and ovarian cancer were seen in patients with hormonal therapy (5.2%) as compared with patients without hormonal therapy (1.8%, p = 0.002). Women with a family history of breast cancer had a higher incidence (6%) of endometrial and ovarian malignancy compared with women without such a history (2.1%, p = 0.003). Chemotherapy did not affect the risk of second malignancy. Conclusion: The most common NBSMs in this study were gynecologic. Family history of breast cancer was a high risk factor for NBSMs. No risk of NBSMs with radiotherapy was observed.

    Full Text Available Giant peritoneal loose bodies are rare lesions, originating from auto-amputated appendices epiploicae. They may cause urinary or gastrointestinal obstruction and, should the radiologist not be familiar with the entity, can potentially be confused with malignant or parasitic lesions.Familiarity with their characteristic computed tomographic features is essential to prevent unnecessary surgery in the asymptomatic patient. We present a case of a 70-year-old man diagnosed with two giant peritoneal loose bodies.

  8. Perfusion lung scintigraphy in primary broncho-pulmonary cancer

    International Nuclear Information System (INIS)

    Research on primary broncho-pulmonary cancer has called extensively on scintigraphy and it seemed interesting to weigh up the pros and cons of the technique in this particular case. Our intention is to sum up objectively from recent documents the applications of scintigraphy in the study of primary broncho-pulmonary cancers and to attempt, on the basis of the results compiled, to show what benefits have been gained from this technique and to find out whether it has any pre-surgical value and of what kind. The technique was invariable; the tracer consists of human albumin macro-aggregates labelled with technetium 99m which by its short half-life and slight penetration enables four exposures to be taken during the same examination (front, back, right and left profiles), thus reducing the risks of mistaken diagnoses due to the use of a single incidence. Similarly the detection method was always the scintillation camera which explores the whole organ at once, considerably shortening the examination time. Lung scintigraphy by perfusion of labelled human albumin macro-aggregates offers the great advantage of being simple to use and harmless. It is easy to understand the important place it has taken in the range of methods available for lung circulation exploration

    Leptomeningeal carcinomatosis (LMC) is a rare complication of cancer that often presents at an advanced stage after obvious metastasis of a primary cancer or locally advanced disease. We present an uncommon case of LMC secondary to pancreatic carcinoma presenting with headache, unilateral VII nerve palsy, and lower extremity weakness. Initial cerebrospinal fluid (CSF) studies were concerning for chronic aseptic meningitis but negative for malignant cells; the diagnosis of tuberculous meningitis was erroneously evoked. Three lumbar punctures were required to capture malignant cells. The diagnosis of LMC was based on CSF examination with cytology/immunohistochemistry and leptomeningeal enhancement on MRI. Post mortem autopsy revealed advanced and diffusely metastatic pancreatic adenocarcinoma. This patient demonstrates that solid tumors can present with leptomeningeal spread that often confuses the treating physician. Fungal or tuberculous meningitis can mimic LMC in the absence of neoplastic signs and negative CSF cytology. This event is exceedingly rare in pancreatic cancer. If the index of suspicion is high, repeat CSF sampling can increase the sensitivity of detection of malignant cells and thus result in the correct diagnosis. PMID:26972704

  10. Radiologically placed tunneled peritoneal catheter in palliation of malignant ascites

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate retrospectively the safety and effectiveness of radiologically placed tunneled peritoneal catheter in palliation of malignant ascites. Between July 2005 and June 2009, 41 tunneled peritoneal catheters were placed under ultrasonographic and fluoroscopic guidance in 40 patients (mean age, 55 years; 22 women) who had symptomatic malignant ascites. No procedure related mortality was observed. Major complication occurred in one patient (2.5%) in the form of serious bacterial peritonitis that necessitated catheter removal. Minor complications such as minor bacterial peritonitis, catheter dislodgement, tunnel infection, and catheter blockage occurred in 11 patients (27.5%). The mean duration of survival after catheter placement was 11.8 weeks. All patients expired of their primary malignancies in the follow-up. Radiologically placed tunneled peritoneal catheter is safe and effective in palliation of symptomatic malignant ascites.

    Full Text Available Abstract Background Laparoscopy has became as the preferred surgical approach to a number of different diseases because it allows a correct diagnosis and treatment at the same time. In abdominal emergencies, both components of treatment – exploration to identify the causative pathology and performance of an appropriate operation – can often be accomplished via laparoscopy. There is still a debate of peritonitis as a contraindication to this kind of approach. Aim of the present work is to illustrate retrospectively the results of a case-control experience of laparoscopic vs. open surgery for abdominal peritonitis emergencies carried out at our institution. Methods From January 1992 and January 2002 a total of 935 patients (mean age 42.3 ± 17.2 years underwent emergent and/or urgent surgery. Among them, 602 (64.3% were operated on laparoscopically (of whom 112 -18.7% – with peritonitis, according to the presence of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than two previous major abdominal surgeries or massive bowel distension were not treated Laparoscopically. Peritonitis was not considered contraindication to Laparoscopy. Results The conversion rate was 23.2% in patients with peritonitis and was mainly due to the presence of dense intra-abdominal adhesions. Major complications ranged as high as 5.3% with a postoperative mortality of 1.7%. A definitive diagnosis was accomplished in 85.7% (96 pat. of cases, and 90.6% (87 of these patients were treated successfully by Laparoscopy. Conclusion Even if limited by its retrospective feature, the present experience let us to consider the Laparoscopic approach to abdominal peritonitis emergencies a safe and effective as conventional surgery, with a higher diagnostic yield and allows for lesser trauma and a more rapid postoperative recovery. Such features make Laparoscopy a challenging alternative to open surgery in the management algorithm for abdominal

    Full Text Available Primary neuroendocrine cancer of the breast (NECB is an extremely raretumor. In 2003, the World Health Organization (WHO recognized this category withthree well-described subtypes: small cell, large cell, and carcinoid-like carcinoma;very few peer-review publications based on the WHO definition were encounteredin the literature, and we conducted a literature search to investigate the reportedincidence, diagnosis, prognosis, hormone receptor status, and treatment options forthis rare tumor. Confirming the breast as an origin of neuroendocrine tumor repre-sents a challenge. The diagnosis is mainly dependent on the exclusion of other extra-mammary organs based on clinical, radiological, and pathological data.Primary neuroendocrine carcinoma of the breast is rare - only about 30cases have been reported in literature. Immunohistochemical examination showingexpression of chromogranin and/or synaptophysin confirms evidence of neuro-endocrine differentiation. Usually foci of neuroendocrine differentiation can be seenin breast carcinoma and are reported to be present in about 2-5% of breast cancercases. Here, we report a case of breast carcinoma in which most of the areas studiedon the tissue section showed neuroendocrine differentiation.Primary neuroendocrine carcinoma of the breast is a group that exhibitsmorphological features similar to those of neuroendocrine tumors of both thegastrointestinal tract and the lung.Case presentationWe report the case of a 50-year-old Caucasian woman with primary smallcell neuroendocrine cancer of the breast, which we characterized with immunohisto-chemical techniques. A palpable and mobile 3.0 cm tumor was located in the upper-outer quadrant of her right breast. After pathological confirmation the patientunderwent 8 cycles of chemotherapy, and subsequent radical mastectomy withaxillary lymph node resection were performed. Microscopically, the tumor consistedpredominantly of a diffuse proliferation of small oat cells

    The results of a controlled clinical trial in the treatment of advanced primary lung cancer are presented. There were 39 patients who entered the present study that was conducted at the Thoracic Surgery Departament of the A.C. Camargo Hospital of the Antonio Prudente Foundation of Sao Paulo, Brazil. The patients were divided in two groups 1) - Radiotherapy with Cobalt 60 plus Chemotherapy. 2) - Chemotherapy only. The radiotherapy was provided by the split dose technic (6.000 rads in 3 cycles of 2.000 rads each). The chemotherapy consisted of the following drugs (5 FU, Metil hidrazina, Methotrexate, Actinomycin D, Oncovin, Cytoxan) administered in 16 cycles, aiming the synchronous funtional blockade. There was no statistically significant difference in survival of the two groups, ie, the first with 19,3 weeks and the second group with 14,6 weeks. (Author)

  3. Stereotactic body radiotherapy (SBRT) for oligometastatic lung tumors from colorectal cancer and other primary cancers in comparison with primary lung cancer

    International Nuclear Information System (INIS)

    Purpose: To analyze local control of oligometastatic lung tumors (OLTs) compared with that of primary lung cancer after stereotactic body radiotherapy (SBRT). Materials and methods: Retrospective record review of patients with OLTs who received SBRT with 50 Gy in 5 fractions. Local control rates (LCRs), toxicities, and factors of prognostic significance were assessed. Results: Twenty-one colorectal OLTs, 23 OLTs from other origins, and 188 primary lung cancers were included. Multivariate analysis revealed only tumor origin was prognostically significant (p < 0.05). The 1-year/2-year LCRs in colorectal OLTs and OLTs from other origins were 80%/72% and 94%/94%, respectively. The LCR in colorectal OLTs was significantly worse than that in OLTs from the other origins and primary lung cancers with pathological and clinical diagnosis (p < 0.05, p < 0.0001 and p < 0.005). Among 44 OLT patients, Grades 2 and 3 radiation pneumonitis were identified in 2 and 1 patients, respectively. No other toxicities of more than Grade 3 occurred. Conclusion: SBRT for OLTs is tolerable. The LCR for OLTs from origins other than colorectal cancer is excellent. However, LCR for colorectal OLTs is worse than that from other origins. Therefore dose escalation should be considered to achieve good local control for colorectal OLTs.

    We have developed an in vivo imaging system consisting of GFP- and DsRed-tagged human colonic cancer cell line, which has peritoneal and lymph node metastatic potential and show high sensitivity to EGFR targeting drugs, and convenient detection devices for GFP and DsRed. The latter includes a small handy fluorescence detection device for external monitoring of the therapeutic effect of the drug and a convenient stereo fluorescent microscope for internal visualization of micrometastases. We applied this imaging system to investigate anti-metastatic effects of EGFR targeting drugs such as gefitinib (Iressa). This system allowed sensitive detection of the development of peritoneal and lymph node metastases from the micrometastasis stage at the cellular level and also permited noninvasive, non-anesthetic monitoring of anti-metastatic effect of the drug in an animal facility without any pretreatment. Significant decreases in the intraabdominal metastatic tumor growth and prevention of inguinal lymph node metastasis by gefitinib treatment could be clearly monitored. These results suggest that convenient, low-cost, true real-time monitoring of therapeutic effect using such a fluorescence-mediated whole body imaging system seems to enhance the speed of preclinical study for novel anti-cancer agents and will allow us to understand the action mechanism of molecular targeting drugs.

    2016-06-01

    Full Text Available BACKGROUND: We set out to examine the activity of γ-glutamyltranspeptidase (GGT in lung cancer and the validity of γ-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG for intraoperative imaging of primary lung cancer. METHODS: GGT activities and mRNA expression levels of GGT1 (one of the GGT subtypes in five human lung cancer cell lines were examined by fluorescence imaging and quantitative reverse transcription polymerase chain reaction. In vivo imaging of an orthotopic A549 xenograft model in nude mice was performed to confirm its applicability to intraoperative imaging. Furthermore, ex vivo imaging of 73 specimens from lung cancer patients were performed and analyzed to calculate the sensitivity/specificity of gGlu-HMRG for lung cancer diagnosis. RESULTS: GGT activities and mRNA expression levels of GGT1 are diverse depending on cell type; A549, H441, and H460 showed relatively high GGT activities and expression levels, whereas H82 and H226 showed lower values. In the in vivo mouse model study, tiny pleural dissemination and hilar/mediastinal lymph node metastasis (less than 1 mm in diameter were clearly detected 15 minutes after topical application of gGlu-HMRG. In the ex vivo study of specimens from patients, the sensitivity and specificity of gGlu-HMRG were calculated to be 43.8% (32/73 and 84.9% (62/73, respectively. When limited to female patients, never smokers, and adenocarcinomas, these values were 78.9% (15/19 and 73.7% (14/19, respectively. CONCLUSIONS: Although GGT activity of lung cancer cells vary, gGlu-HMRG can serve as an intraoperative imaging tool to detect small foci of lung cancer when such cells have sufficient GGT activity.

    Cancer dissemination to peritoneal surfaces was, in the past, a lethal condition with a limited survival. Clinical and pharmacologic research have shown that options for both treatment and prevention are now reality. The diseases most commonly treated include peritoneal dissemination from appendiceal malignancy, colorectal malignancy, and peritoneal mesothelioma. Selection factors are important to minimize the number of treated patients who will experience short-term benefit. Treatments invol...

    Recipients of kidney transplantation have elevated risk of developing cancer. There are limited data on cancer risk in recipients of kidney retransplantation. We used data from the Transplant Cancer Match Study, which links the U.S. transplant registry with 15 cancer registries. Cancer incidence in recipients of kidney retransplantation and primary kidney transplants was compared utilizing Poisson regression, adjusting for demographic and medical characteristics. We assessed 109 224 primary recipients and 6621 retransplants. Compared to primary recipients, retransplants were younger (median age 40 vs. 46 yr), had higher PRA, and more often received induction with polyclonal antibodies (43% vs. 25%). A total of 5757 cancers were observed in primary recipients and 245 in retransplants. Overall cancer risk was similar in retransplants compared with primary recipients (incidence rate ratio [IRR] 1.06, 95% CI 0.93-1.20, adjusted for age, gender, race/ethnicity, PRA, and use of polyclonal induction). However, renal cell carcinoma (RCC) occurred in excess among retransplants (adjusted IRR 2.03, 95% CI 1.45-2.77), based on 514 cases in primary recipients and 43 cases in retransplants. Overall cancer risk did not differ in retransplants compared to primary recipients. Increased risk of RCC may be explained by the presence of acquired cystic kidney disease, which is more likely to develop with additional time with kidney disease and time spent on dialysis waiting for retransplantation.

    Full Text Available Gastrointestinal complications are common among patients on peritoneal dialysis. Risk factors for the development of gastrointestinal complications in this patient population include: toxic effects of uremic toxins, frequent use of nonsteroidal anti-inflammatory drugs, Helicobacter pylori infection, angiodysplasia, increased intra-abdominal pressure, use of bioincompatible solution for peritoneal dialysis, increased glucose in solutions for peritoneal dialysis, secondary hyperparathyroidism (hypercalcemia, a disorder of lipid metabolism (hypertriglyceridemia, and the duration of peritoneal dialysis treatment. The most important non-infectious gastrointestinal complications in patients on peritoneal dialysis are: gastrointestinal bleeding, herniation and leaking of the dialysate from the abdomen (increased intra-abdominal pressure, impaired lung function (intra-abdominal hypertension, acute pancreatitis, and encapsulating sclerosis of the peritoneum. Intra-abdominal hypertension is defined as IAP ≥ 12 mmHg. Pouring the peritoneal dialysis solution leads to increased intra-abdominal pressure, which results in the development of hernias, pleuro-peritoneal dialysate leakage (hydrothorax, and restrictive pulmonary dysfunction. Risk factors for the development of acute pancreatitis in this patient population include: uraemia, secondary hyperparathyroidism with hypercalcemia, hypertriglyceridemia, features of the peritoneal dialysis solution (osmolarity, acidity, glucose, chemical irritation, and calcium in the solution for peritoneal dialysis lead to “local hypercalcemia”, toxic substances from the dialysate, the bags and tubing, and peritonitis and treatment of peritonitis with antibiotics and anticoagulants. Encapsulating sclerosis of the peritoneum is rare and is the most serious complication of long-term peritoneal dialysis. It is characterized by thickening of the peritoneum, including cancer, and signs and symptoms of obstructive ileus

  4. Radiotherapeutic concepts in cancer of unknown primary site

    International Nuclear Information System (INIS)

    The term cancer of unknown primary (CUP) encompasses a group of entities which differ to a great extent regarding etiology, prognosis and therapeutic management. The aim of the study was an elaboration of the role of radiotherapy in CUP syndrome. Systematic literature search and specification of the available treatment options. Radiotherapy is an integral part of interdisciplinary management approaches for patients with CUP in both curative and palliative situations. Radio-oncological techniques, such as intensity-modulated radiotherapy and stereotactic body radiotherapy increase the therapeutic window. Modern diagnostic modalities from radiology and nuclear medicine are the cornerstone of radiotherapeutic interventions, especially in terms of target volume definition and pretherapeutic staging. In the interdisciplinary setting radiation oncology offers the possibility of curative and often organ preserving approaches in patients with axillary and cervical CUP. In addition, improvement and preservation of quality of life can be achieved in patients with metastatic disease. Radiation oncology is a crucial component of the interdisciplinary management of patients with CUP. Therapeutic decisions in patients with CUP should be made in an interdisciplinary setting. (orig.)

    The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics. PMID:24761922

  6. Rectum separation in patients with cervical cancer for treatment planning in primary chemo-radiation

    International Nuclear Information System (INIS)

    To proof feasibility of hydrogel application in patients with advanced cervical cancer undergoing chemo-radiation in order to reduce rectal toxicity from external beam radiation as well as brachytherapy. Under transrectal sonographic guidance five patients with proven cervical cancer underwent hydro gel (20 cc) instillation into the tip of rectovaginal septum adherent to posterior part of the visible cervical tumor. Five days after this procedure all patients underwent T2 weighted transversal and sagittal MRI for brachytherapy planning. MRI protocol included T2 weighted fast spin echo (FSE) imaging in sagittal, coronal and para-axial orientation using an 1.5 Tesla MRI. Separation of anterior rectal wall and cervix was documented. Hydrogel application was uneventful in all patients and no toxicity was reported. Separation ranged from 7 to 26 mm in width (median 10 mm). The length of the separation varied between 18 and 38 mm (median 32 mm). In all patients displacement was seen in the posterior vaginal fornix, and/or at the deepest part of uterine cervix depending on the extension of the cul-de-sac in correlation to the posterior wall of the uterus. In patients with bulky tumor and/or deep (vaginal) extend of peritoneal cavity tumour was seen mainly cranial from the rectovaginal space and therefore above the hydrogeI application. Only in the extra-peritoneal (lower) part of the cervix a good separation could be achieved between the rectum and cervix. Hydrgel instillation in patients with cervial cancer undergoing chemoradiation is safe and feasible. Because of the loose tissue of the cul-de-sac and its intra- and extraperitoneal part, hydrogel instillation of 20 cc did not result in a sufficient separation of the cervix from anterior wall

    2004-01-01

    To investigate the expression and clinical significance of p27kip1 protein in primary liver cancer, the expression of p27kip1 protein and the relationship with clinicopathological factors were studied in primary liver cancer by using SABC immunohistochemical staining in specimens of 40 cases of primary liver cancer and 20 cases of liver cirrihosis. Our results showed that positive expression rate of p27kip1 protein in primary liver cancer was 37.5 % (15/40), which was lower than that in benign lesion of liver 80.0 % (16/20, P<0.01). The expression level of p27kip1 protein in primary liver cancer showed significant differences in tumor size, Edmonson histological grade, portal invasion, lymph node metastasis, TNM stage (P<0.05, for all), but not significantly correlated with patient's age and histological types. Log rank test showed that the p27kip1 expression was significantly related with prognosis of the patients (P<0.05), and the prognosis of the patients with p27kip1 positive expression was markedly better than that of those with p27kip1 negative expression. It is concluded that the expression of p27kip1 was significantly related clinicopathological factors of primary liver cancer. p27kip1 protein may be used as a novel tumor marker for primary liver cancer.

    Aim: To establish and characterize primary lung cancer cell lines from Chinese population.Methods: Lung cancer specimens or pleural effusions were collected from Chinese lung cancer patients and cultured in vitro with ACL4 medium (for non-small cell lung carcinomas (NSCLC)) or HITES medium (for small cell lung carcinomas (SCLC)) supplemented with 5%FBS. All cell lines were maintained in culture for more than 25 passages. Most of these cell lines were further analyzed for oncogenic mutations, karyotype, cell growth kinetics, and tumorigenicity in nude mice.Results: Eight primary cell lines from Chinese lung cancer patients were established and characterized, including seven NSCLC cell lines and one SCLC cell line. Five NSCLC cell lines were found to harbor epidermal growth factor receptor (EGFR) kinase domain mutations.Conclusion: These well-characterized primary lung cancer cell lines from Chinese population provide a unique platform for future studies of the ethnic differences in lung cancer biology and drug response.

    The vasoactive hormone angiotensin II initiates its major hemodynamic effects through interaction with AT1 receptors, a member of the class of G protein-coupled receptors. Acting through its AT1R, angiotensin II regulates blood pressure and renal salt and water balance. Recent evidence points to additional pathological influences of activation of AT1R, in particular inflammation, fibrosis and atherosclerosis. The transcription factor nuclear factor κB, a key mediator in inflammation and atherosclerosis, can be activated by angiotensin II through a mechanism that may involve arrestin-dependent AT1 receptor internalization. Peritoneal dialysis is a therapeutic modality for treating patients with end-stage kidney disease. The effectiveness of peritoneal dialysis at removing waste from the circulation is compromised over time as a consequence of peritoneal dialysis-induced peritoneal fibrosis. The non-physiological dialysis solution used in peritoneal dialysis, i.e. highly concentrated, hyperosmotic glucose, acidic pH as well as large volumes infused into the peritoneal cavity, contributes to the development of fibrosis. Numerous trials have been conducted altering certain components of the peritoneal dialysis fluid in hopes of preventing or delaying the fibrotic response with limited success. We hypothesize that structural activation of AT1R by hyperosmotic peritoneal dialysis fluid activates the internalization process and subsequent signaling through the transcription factor nuclear factor κB, resulting in the generation of pro-fibrotic/pro-inflammatory mediators producing peritoneal fibrosis.

  14. CT features of peritonitis associated with continuous ambulatory peritoneal dialysis

    International Nuclear Information System (INIS)

    To evaluate the CT findings of peritonitis associated with continuous ambulatory peritoneal dialysis(CAPD). We retrospectively analyzed CT scans of 14 symptomatic patients with peritonitis after CAPD. Diffuse abdominal pain was present in 11, fever in two, and abdominal mass with vomiting in one. The mean duration of CAPD ranged from 10 months to 5 years(mean : 3.9 years). On abdominal CT, we evaluated the presence and location of ascites, bowel wall thickening, cocoon formation, the pattern of enhancement of peritoneal thickening, the presence of calcifications in the peritoneum, and mesenteric and omental change. On enhanced CT, multiloculated ascites was observed in all cases(n=14) ; it was located mainly in the pelvic cavity with small multi-loculated fluid collections in the peritoneal cavity(n=13), including the lesser sac(n=3). In one patient, ascites was located in the space between the greater omentum and anterior peritoneal surface. CT showed ileus in 12 cases, small bowel wall thickening in 11, and cocoon formation in five. Uneven but smooth thickening of the peritoneum, with contrast enhancement, was seen in eight cases, and in five of these, peritoneal thickening was more prominent in the anterior peritoneum. Other findings included reticular opacity in two cases, hematoma of the rectus muscle in one, and umbilical hernia in one. Multiloculated fluid collection, ileus, small bowel wall thickening, uneven but smooth peritoneal thickening, and cocoon formation appear to be CT features of CAPD peritonitis

    Worldwide, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been used for nearly 3 decades to treat peritoneal metastases (PM), improve quality of life, and prolong survival substantially in selected patients. In India, the use of the combined modality of treatment dates back a decade with majority of the efforts taking place within the last 5 years. The first PSOGI workshop (India) held in April 2015, at Bangalore, India offered an opportunity for Indian surgeons performing CRS and HIPEC to share their experience. To study the methodologies of CRS and HIPEC (hospital set up, equipment, training and surgical background) as well as the outcomes in terms of perioperative morbidity and mortality and short and long term survival of patients treated in India, Indian surgeons who had treated at least 10 patients with this combined modality were invited to present their experience. Data collection was retrospective. Analysis of the pooled data was carried out. Eight surgeons treated 384 patients with CRS and HIPEC over a period of 10 years. The commonest primary sites were ovary (as first line therapy n = 124), followed by appendix, including pseudomyxoma peritonei (n = 99), colorectum (n = 77), recurrent ovary (as second line therapy, n = 33), stomach (n = 15), primary peritoneal cancer (n = 10), peritoneal mesothelioma (n = 9) and rare tumors in 17 patients. The weighted mean PCI for all 384 patients was 18.25. 349/384 patients (90.88 %) had a complete cytoreduction (completeness of cytoreduction score of CC-0/1). Grade 3-5 complications developed in 108 patients (27.34 %) and 30 day mortality occurred in 28 (7.29 %) patients. This study showed that CRS and HIPEC can be performed with an acceptable morbidity and mortality in Indian patients. Most of the surgeons are on the learning curve and further improvement in these outcomes is expected over a period of time. Pooling of data related to both common and rare

    2010-01-01

    BACKGROUND: Primary myeloifbrosis (PMF) is a myelopro-liferative disorder characterized by bone marrow ifbrosis. Extra-medullary hematopoiesis sometimes occurs even in the peritoneal cavity, apart from organs such as the liver, spleen, and lymph nodes. This may sometimes be complicated by spontaneous infection and complications. We report a rather unusual case of PMF, who presented as an emergency with spontaneous peritonitis to general surgery department and had a fulminant clinical course. METHOD: A clinical case note review was done and a literature search was undertaken. RESULTS: A rather unusual case of PMF, who presented as an emergency with spontaneous peritonitis to general surgery department. The patient underwent a laparotomy and had a fulminant clinical course. CONCLUSIONS: Peritonitis in myeloifbrosis may have a number of causes. Clinicians need to be aware of them and provide conservative management prior to surgical treatment.

  19. Sclerosing Encapsulating Peritonitis; Review

    Norman O. Machado

    2016-05-01

    Full Text Available Sclerosing encapsulating peritonitis (SEP is a rare chronic inflammatory condition of the peritoneum with an unknown aetiology. Also known as abdominal cocoon, the condition occurs when loops of the bowel are encased within the peritoneal cavity by a membrane, leading to intestinal obstruction. Due to its rarity and nonspecific clinical features, it is often misdiagnosed. The condition presents with recurrent episodes of small bowel obstruction and can be idiopathic or secondary; the latter is associated with predisposing factors such as peritoneal dialysis or abdominal tuberculosis. In the early stages, patients can be managed conservatively; however, surgical intervention is necessary for those with advanced stage intestinal obstruction. A literature review revealed 118 cases of SEP; the mean age of these patients was 39 years and 68.0% were male. The predominant presentation was abdominal pain (72.0%, distension (44.9% or a mass (30.5%. Almost all of the patients underwent surgical excision (99.2% without postoperative complications (88.1%.

    Objective: To investigate the associations between the different breast cancer subtypes and survival in Chinese women with operable primary breast cancer. Methods: A total of 1538 Chinese women with operable primary breast cancer were analyzed in this study, the median follow-up was 77 months. Estrogen receptor (ER), progesterone receptor (PR), and HER2 status were available for these patients. Results: Luminal A (ER+ and/or PR+, HER2-) had a favorable disease-free survival (DFS) and overall survival (OS)compared with other subtypes in the entire cohort. Using the luminal A as a reference, among the patients with lymph node positive disease, HER2+ (ER-, PR-, HER2+) had the worst DFS (hazard ratio, HR=1.80, 95% Cl 1.11 to 2.91,P=0.017) and luminal B (ER+ and/or PR+, HER2+) had the worst OS (HR=2.27, 95% CI 1.50 to 3.45, P<0.001); among the patients with lymph node negative disease, triple-negative (ER-, PR-, HER2-) had the worst DFS (HR=2.21, 95% Cl 1.43 to 3.41, P<0.001), whereas no significant difference in DFS between HER2+ and luminal B or luminal A was observed. Conclusion: As compared with luminal A, luminal B and HER2+ have the worst survival in patients with lymph node positive disease, but this is not the case in patients with lymph node negative disease; triple-negative subtype has a worse survival in both lymph node positive and lymph node negative patients.

  3. Second primary cancers after radiation for prostate cancer: a review of data from planning studies

    International Nuclear Information System (INIS)

    A review of planning studies was undertaken to evaluate estimated risks of radiation induced second primary cancers (RISPC) associated with different prostate radiotherapy techniques for localised prostate cancer. A total of 83 publications were identified which employed a variety of methods to estimate RISPC risk. Of these, the 16 planning studies which specifically addressed absolute or relative second cancer risk using dose–response models were selected for inclusion within this review. There are uncertainties and limitations related to all the different methods for estimating RISPC risk. Whether or not dose models include the effects of the primary radiation beam, as well as out-of-field regions, influences estimated risks. Regarding the impact of IMRT compared to 3D-CRT, at equivalent energies, several studies suggest an increase in risk related to increased leakage contributing to out-of-field RISPC risk, although in absolute terms this increase in risk may be very small. IMRT also results in increased low dose normal tissue irradiation, but the extent to which this has been estimated to contribute to RISPC risk is variable, and may also be very small. IMRT is often delivered using 6MV photons while conventional radiotherapy often requires higher energies to achieve adequate tissue penetration, and so comparisons between IMRT and older techniques should not be restricted to equivalent energies. Proton and brachytherapy planning studies suggest very low RISPC risks associated with these techniques. Until there is sufficient clinical evidence regarding RISPC risks associated with modern irradiation techniques, the data produced from planning studies is relevant when considering which patients to irradiate, and which technique to employ

    ABSTRACT Objective:To study the value of the differentially expressed proteins from primary and recurrent ovarian cancer serum for early diagnosis of primary and recurrent ovarian cancer.Methods:WCX kit(BrukerDaltonicsGraBH) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS) technology were used to detect serum samples from49 patients with primary ovarian cancer and21 patients with recurrent disease.Results:In the mass range(Mr) from1000 to12000Da, eight differentially expressed protein peaks were screened from primary ovarian cancer serum.Among them, four protein peaks withMr1457,1857,2202, 7761 were lowly expressed and the others withMr2946,5333,5859,5901 were highly expressed. Ten diferentially expressed protein peaks were screened from recurrent ovarian cancer serum. Among them,1944,1980,2080,2661,2993,4450,4659,5359Da protein expressions were increased significantly, and1897,7868Da protein expressions were decreased significantly.The pattern of primary ovarian cancer was applied to8 early-stage ovarian cancer serum samples, and7 serum samples were successfully predicted with the accuracy of87.5%.The pattern of recurrent ovarian cancer was applied to9 without pelvic or abdominal mass recurrent ovarian cancer serum samples, and8 serum samples were successfully predicted with the accuracy of 88.9%.Conclusions:Combination ofMALDI-TOF-MS andWCX kit technology can directly screen the diferrential expressed protein from primary and recurrent ovarian cancer serum.They have clinical significance for enhancement of sensitivity and specificity of ovarian cancer diagnosis.

  5. Imaging screening of breast cancer: primary results in 5307 cases

    International Nuclear Information System (INIS)

    Objective: To discuss the values of three screening methods for the detection of early breast cancer, and to analyze the features of the screening cancer. Methods: The first screening of breast cancer were performed in 5307 women who aged from 20 to 76 years with median age of 49 years. The three screening methods included physical examination with ultrasound and mammography, physical examination with mammography and mammography only. The rate of recall, biopsy, cancer detection of three methods were analyzed and the mammographic findings were reviewed. Chi-square test or Fisher's exact test were used for the statistics. Results: The recall rates were 4.90% (49/1001), 6.90% (166/2407) and 4. 48% (85/1899) in three methods respectively, the biopsy rates were 1.60% (16/1001), 1.04% (25/2407) and 0.63% (12/1899), the cancer detection rates were 0.50% (5/1001), 0.17% (4/2407) and 0 (0/1899). There were statistical differences among the three groups (χ2=12.99,6.264,8.764, P<0.05). Physical examination with ultrasound and mammography had the highest cancer detection rate, ten breast cancers were detected and 8 were early stage breast cancer. Of seven cancers detected by mammography, only two were found by ultrasound. A cluster of calcifications were found in 2 cases, linear calcifications in 2 cases. One case presented as a asymmetric density, one as a asymmetric density with calcifications, one as multiple nodules with a cluster of calcifications. Two breast cancers presented as asymmetric density were missed on mammography and diagnosed correctly after retrospective review. Conclusion: Physical examination with ultrasound and mammography is the best method for breast cancer screening. The breast cancer can be detected by mammography earlier than other methods.

    Approximately 50% of prostate cancers are characterized by TMPRSS2 (transmembrane protease serine 2)-ERG (avian v-ets erythroblastosis virus E26 oncogene homolog) gene fusions resulting in an androgen-regulated overexpression of the transcription factor ERG. Some studies have suggested prognostic or predictive relevance of ERG status in prostate cancer. Such concepts could be impaired by extensive ERG heterogeneity in analyzed tumors. The aim of this study was to analyze the extent of heterogeneity for TMPRSS2-ERG fusion in prostate cancer. To enable large-scale studies on the extent of heterogeneity of biomarkers in prostate cancer, a heterogeneity tissue microarray containing samples from 10 different tumor blocks of 190 large prostate cancers selected from a consecutive series of 480 radical prostatectomies was developed. ERG expression was analyzed by immunohistochemistry. Positive ERG immunostaining was found in arrayed cancer-containing samples from 103 of the 178 analyzable patients (58%). ERG immunostaining was homogeneously positive in 29 prostate cancers (16%), whereas heterogeneous ERG positivity was seen in 74 cancers (42%). ERG heterogeneity was within one tumor focus (intrafocal heterogeneity) in 69 cases (93% of heterogeneous cases) and between different tumor foci (interfocal heterogeneity) in 5 cases (7%). Marked intrafocal heterogeneity challenges the concept of TMPRSS2-ERG fusion always representing an early step in prostate cancer development. Marked heterogeneity also compromises the concept of analyzing ERG status for treatment decisions in diagnostic needle core biopsies. PMID:22899295

    Individuals diagnosed with colorectal cancer (CRC) are at risk of developing a metachronous CRC. We examined the associations between personal, tumour-related and lifestyle risk factors, and risk of metachronous CRC. A total of 7,863 participants with incident colon or rectal cancer who were recruited in the USA, Canada and Australia to the Colon Cancer Family Registry during 1997-2012, except those identified as high-risk, for example, Lynch syndrome, were followed up approximately every 5 years. We estimated the risk of metachronous CRC, defined as the first new primary CRC following an interval of at least one year after the initial CRC diagnosis. Observation time started at the age at diagnosis of the initial CRC and ended at the age at diagnosis of the metachronous CRC, last contact or death whichever occurred earliest, or were censored at the age at diagnosis of any metachronous colorectal adenoma. Cox regression was used to derive hazard ratios (HRs) and 95% confidence intervals (CIs). During a mean follow-up of 6.6 years, 142 (1.81%) metachronous CRCs were diagnosed (mean age at diagnosis 59.8; incidence 2.7/1,000 person-years). An increased risk of metachronous CRC was associated with the presence of a synchronous CRC (HR = 2.73; 95% CI: 1.30-5.72) and the location of cancer in the proximal colon at initial diagnosis (compared with distal colon or rectum, HR = 4.16; 95% CI: 2.80-6.18). The presence of a synchronous CRC and the location of the initial CRC might be useful for deciding the intensity of surveillance colonoscopy for individuals diagnosed with CRC. PMID:27098183

    The paper discusses the capability for active movement in an extracellular matrix, wherein remodeling of the cytoskeleton by actin binding proteins plays a significant role in metastases formation. We studied the expression of actin binding proteins and β-catenin in tissues of primary tumors and metastases of ovarian and breast cancer. Contents of p45 Ser β-catenin and the actin severing protein gelsolin were decreased in metastases of ovarian cancer relative to primary tumors. The level of the cofilin, functionally similar to gelsolin, was significantly higher in metastases compared to primary ovarian and breast tumor tissue. In breast cancer, significant increase in the number of an actin monomer binder protein thymosin-β4 was observed in metastases as compared to primary tumors. The data obtained suggest the involvement of locomotor proteins in metastases formation in ovarian and breast cancer.

  11. Wnt3a expression is associated with MMP-9 expression in primary tumor and metastatic site in recurrent or stage IV colorectal cancer

    International Nuclear Information System (INIS)

    The wnt/β-catenin signaling pathway is known to affect in cancer oncogenesis and progression by interacting with the tumor microenvironment. However, the roles of wnt3a and wnt5a in colorectal cancer (CRC) have not been thoroughly studied. In the present study, we investigated the expression of wnt protein and the concordance rate in primary tumor and metastatic sites in CRC. To determine the relationship of wnt proteins with invasion related protein, we also analyzed the association between wnt protein expression and the expression of matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor receptor-2 (VEGFR-2). Tumor tissue was obtained from eighty-three paraffin- embedded blocks which were using resected tissue from both the primary tumor and metastatic sites for each patient. We performed immunohistochemical staining for wnt3a, wnt5a, β-catenin, MMP-9 and VEGFR-2. Wnt3a, wnt5a, β-catenin, and MMP-9 expression was high; the proteins were found in over 50% of the primary tumors, but the prevalence was lower in tissue from metastatic sites. The concordance rates between the primary tumor and metastatic site were 76.2% for wnt5a and 79.4% for wnt3a and β-catenin, but VEGFR-2 was expressed in 67.4% of the metastatic sites even when not found in the primary tumor. Wnt3a expression in primary tumors was significantly associated with lymph node involvement (p = 0.038) and MMP-9 expression in the primary tumor (p = 0.0387), mesenchyme adjacent to tumor (p = 0.022) and metastatic site (p = 0.004). There was no other relationship in the expression of these proteins. Vascular invasion in primary tumor tissue may be a potential prognostic marker for liver metastasis, but no significant association was observed among the wnt protein, MMP-9, and VEGFR-2 for peritoneal seeding. In survival analysis, β-catenin expression was significantly correlated with overall survival (p = 0.05). Wnt3a and wnt5a expression had a concordance rate higher than 60% with a

    Remnant gastric cancer, most frequently defined as cancer detected in the remnant stomach after distal gastrectomy for benign disease and those cases after surgery of gastric cancer at least 5 years after the primary surgery, is often reported as a tumor with poor prognosis. The Task Force of Japanese Gastric Cancer Association for Research Promotion evaluated the clinical impact of remnant gastric cancer by systematically reviewing publications focusing on molecular carcinogenesis, lymph node status, patient survival, and surgical complications. A systematic literature search was performed using PubMed/MEDLINE with the keywords "remnant," "stomach," and "cancer," revealing 1154 relevant reports published up to the end of December 2014. The mean interval between the initial surgery and the diagnosis of remnant gastric cancer ranged from 10 to 30 years. The incidence of lymph node metastases at the splenic hilum for remnant gastric cancer is not significantly higher than that for primary proximal gastric cancer. Lymph node involvement in the jejunal mesentery is a phenomenon peculiar to remnant gastric cancer after Billroth II reconstruction. Prognosis and postoperative morbidity and mortality rates seem to be comparable to those for primary proximal gastric cancer. The crude 5-year mortality for remnant gastric cancer was 1.08 times higher than that for primary proximal gastric cancer, but this difference was not statistically significant. In conclusion, although no prospective cohort study has yet evaluated the clinical significance of remnant gastric cancer, our literature review suggests that remnant gastric cancer does not adversely affect patient prognosis and postoperative course.

    Leptomeningeal metastasis (LM) is an uncommon presentation of relapse in breast cancer, which is associated with poor clinical outcomes and poor prognosis. Notably, LM most commonly occurs in breast cancer. The aim of the present review was to investigate the occurrence of LM as the primary presentation of relapse following remission in breast cancer patients and to determine whether specific histological subtypes are predisposed to meningeal metastases. In addition, the present review evaluated whether patients presenting with LM as the primary site of relapse exhibit differences in survival when compared with patients exhibiting metastasis to other sites. Cross-sectional studies have demonstrated that LM is commonly associated with other sites of distant metastasis including lung, liver and bone metastases. The histological breast cancer subtype most commonly associated with LM was invasive lobular carcinoma, while triple-negative breast cancer patients appear to be predisposed to the development of LM when considering the overall prevalence of histological breast cancer subtypes. At present, data regarding LM as the primary site of relapse are limited due to its rarity as the first site of metastasis in breast cancer. Case-controlled studies are required to investigate the incidence of LM as the primary site of recurrence in breast cancer patients as this would enable treatment standardization and identification of prognostic factors for improved survival.

Selecting the correct health behaviors and preventing exposure to convinced environmental risk factors can help to prevent the expansion of cancer. Scientists guess that as many as 30-40 percent of all cancer-related deaths are caused by human behaviors such as smoking, consumption of alcohol, poor diet quality and physical inactivity. This result explains the tendency in the following behaviors that can influence the possibility of getting cancer, especially oral cancer in addition to providing information and classes about healthy eating habits and a subsequent healthy lifestyle at home. In fact, a diet rich in fresh fruits, whole grains and vegetables can decrease the risk of the oral cancer because of certain compounds such as vitamin C, E, carotenoids and lycopene. Moreover, limit consumption of meat, particularly processed meat, and replace it with vegetable proteins and fish (rich of omega 3 are helpful and effective.

    Full Text Available A well-defined but rare entity of Benign Cystic Peritoneal Mesothelioma (BCPM is reported. The aetiology of this neoplasm remains obscure. The presenting features make a precise preoperative diagnosis difficult but information provided by computed tomography and cytology may help. A firm diagnosis can only come from an electronic microscopy or immunohistological examination of the tumour. Diagnostic accuracy and diligent follow up are essential because, although the tumour is considered benign, it does tend towards local recurrence. [Int J Res Med Sci 2014; 2(2.000: 762-764

    Full Text Available Abstract Background With the prospect of increasing prevalence of cancer, the issue of multiple primary cancers becomes more relevant. The aim of this study was to estimate the risk of developing a tobacco-related subsequent primary cancer (TRSPC in persons with a tobacco-related first primary cancer (TRFPC compared with the general population in Bavaria, Germany. Methods Using data from the Population-Based Cancer Registry Bavaria, we analyzed TRFPC and TRSPC diagnosed in Bavaria between 2002 and 2008 to estimate the relative and absolute risk of developing TRSPC using standardized incidence ratios (SIR and excess absolute risks (EAR. Results 121,631 TRFPC in men and 75,886 respective cancers in women were registered, which in 2.5% of male and 1.2% of female cancer patients were followed by at least one TRSPC. In both males and females, the highest increased risks compared to the general population were found within the group of cancer in the mouth/pharynx, oesophagus, larynx, and lung/bronchus. Conclusions With respect to cancer in the mouth/pharynx, oesophagus, larynx, lung/bronchus, kidney, urinary bladder and urinary tract, smoking was confirmed as a shared risk factor based on our finding of mutually significantly increased risks of TRSPC. The results of this study illustrate the importance of smoking cessation and of continued follow-up care especially of smokers with the aforementioned TRFPC to detect TRSPC at an early stage.

  18. Primary breast cancer induces pulmonary vascular hyperpermeability and promotes metastasis via the VEGF-PKC pathway.

    The lung is one of the most frequent target organs for breast cancer metastasis. When breast cancer cells from a primary tumor do not colonize the lung, which we named the premetastatic phase, the microenvironment of the lung has already been influenced by the primary tumor. However, little is known about the exact premetastatic alteration and regulatory mechanisms of the lung. Here, we used 4T1 cells (a mouse breast cancer cell line which can specifically metastasize to the lung) to build a mouse breast cancer model. We found that primary breast tumor induced increased pulmonary vascular permeability in the premetastatic phase, which facilitated the leakage of rhodamine-dextran and the extravasation of intravenous therapy injected cancer cells. Furthermore, tight junctions (TJs) were disrupted, and the expression of zonula occludens-1(ZO-1), one of the most important components of tight junctions, was decreased in the premetastatic lung. In addition, elevated serum vascular endothelial growth factor (VEGF) was involved in the destabilization of tight junctions and the VEGF antagonist bevacizumab reversed the primary tumor-induced vascular hyperpermeability. Moreover, activation of the protein kinase C (PKC) pathway disrupted the integrity of TJs and accordingly, the disruption could be alleviated by blocking VEGF. Taken together, these data demonstrate that primary breast cancer may induce tight junction disruptions in the premetastatic lung via the VEGF-PKC pathway and promote pulmonary vascular hyperpermeability before metastasis. © 2015 Wiley Periodicals, Inc.

  19. Multiple primary cancers in Denmark 1943-80; influence of possible underreporting and suggested risk factors

    International Nuclear Information System (INIS)

    The risk of developing a second primary cancer was studied among 171,749 men and 208,192 women who were reported to the Danish Cancer Registry between 1943 and 1980. Only those who survived at least two months were included in the analysis, and more than 1.7 million person-years of observation were accrued. Altogether, 15,084 second primary cancers developed, of which 13,231 were in organs other than the initial or adjacent site [relative risk (RR) = 1.01]. Adjustment for possible underreporting of multiple primary cancers increased the RR to 1.24, which stresses the need for detailed knowledge of registration procedures interpreting results from cancer registries. The unadjusted RR for all sites increased with time, from 0.94 during the first decade of follow-up (excluding the first year) to 1.13 among 30-year survivors, whereas the adjusted RR increased from 1.08 to 1.41. Elevated risks were observed for sites thought to have a common etiology. For example, cancers of smoking-related sites were increased in both directions following cancers of the oral cavity, respiratory tract, and urinary organs. For cancers suspected to have a hormone- or dietary fat-related association, significant reciprocal relationships were seen among cancers of the endometrium, ovary, and colon. Cancer treatment probably is an important factor in second cancer development, even when judged indirectly in the present study. For example, radiotherapy may have been responsible for an elevated risk of subsequent cancers of the thyroid, breast, colon, rectum, bladder, and connective tissue in long-term survivors. Chemotherapy may have increased the risk of subsequent leukemias

    The increasing number of new cases of cancer highlights the relevance of primary prevention for cancer control, which is influenced, among other factors, by the population's health-related knowledge. Therefore, we aimed to describe cancer-related knowledge in Portugal, including perception of risk, awareness of cancer causes and preventive behaviours. We evaluated 1624 Portuguese-speaking dwellers, aged between 16 and 79 years, through face-to-face interviews conducted using a structured questionnaire. We computed adjusted (sex, age, education) regression coefficients and prevalence ratios, using linear and Poisson regression, respectively, to quantify associations with cancer-specific knowledge. The proportions of nonresponse ranged from 13.4 to 63.5% for the most frequent cancer in Portugal and the leading cause of cancer, respectively. The mean of the estimated lifetime risk of cancer in the Portuguese population was 37.0%. A total of 47.5% of the respondents identified breast cancer as the most frequent in Portugal, 72.0% named lifestyles as the leading cause of cancer and 40.2% selected not smoking as the most important preventive behaviour. Lower levels of education were associated with higher proportions of nonresponse, but not consistently with inaccurate knowledge. Men provided lower estimates of the lifetime risk of cancer, indicated breast cancer less frequently and more often lung cancer as the most frequent, and were more likely to select not smoking as the most important preventive behaviour. The present study provides relevant data on knowledge of cancer prevention, which may be used for the planning and evaluation of awareness-raising and primary prevention interventions in Portugal.

    Full Text Available Carcinoma of unknown primary origin (CUP accounts for 2-10% of all malignancies. The apparent absence of the primary tumour, the development of early, uncommon systemic metastases and the resistance to therapy and poor prognosis are hallmarks of this heterogeneous clinical entity and are a challenge for physicians. The diagnostic workup of patients with CUP includes a large amount of histopathological examination, as well as the use of imaging techniques that often fail to identify the primary tumour. Therefore, the optimal workup and treatment for these patients remains to be determined. Molecular diagnostic tools, such as DNA microarray analysis, could help in the search for "lost" CUP origin and guide the further treatment approach. We report the case of a 66-year-old man, with mediastinal lymph nodes metastasis of carcinoma and neurological syndrome with diplopia and balance disorders, in which many exams have been performed without finding the primary tumour.

  2. CT findings of mediastinal lymph nodes in tuberculous lymphadenitis and metastasis of primary lung cancer

    International Nuclear Information System (INIS)

    We analyzed pre and post enhanced CT scan of eight two pathologically proven patients among which forty nine cases were pulmonary tuberculosis and thirty three patients, primary lung cancer, who had mediastinal lymphadenopathy, with special attentions to nodal architectures, numbers and locations. The results were as follows: 1. Lymph nodes abnormality was found in its average number of 1.2 nodes in tuberculosis and 2.8 nodes in primary lung cancer. 2, The location of abnormal lymph nodes were 4R (17.5%), 10R (17.5%) and 5 (14.0%) in order of frequency in tuberculosis, and 4R (17.6%), 10R (14.3%) and 7 (14.3%) in order of frequency in primary lung cancer. 3. In the feature of post enhanced lymph nodes, the central low density type was the most frequent in tuberculosis (61.4%). The most frequent type in primary lung cancer was the homogenous type (79.1%). 4. The incidence of lymph node calcification were as twice in tuberculous (67.3%) than in primary lung cancer (39.4%). 5. In order findings, parenchymal mass density (78.8% in Ca/12.2% in Tb) and pleural effusion (27.3% in Ca/10.2% in Tb) were more frequent in primary lung cancer, but parenchymal calcification (27.3% in Ca/49.0% in Tb) was more frequent in tuberculosis. The cavity formation of primary lung cancer (27.3%) was found to be as the same frequency as in tuberculosis (20.4%)

  3. Epidermal growth factor receptor in primary human lung cancer

    International Nuclear Information System (INIS)

    Cell membranes were prepared from 12 human lung cancers for the study of the expression of epidermal growth factor receptors (EGFR). EGFR concentration was estimated by ligand binding studies using 125I-radiolabeled EGF. The dissociation constants of the high affinity sites were identical, 1.48 nmol and 1.1 nmol in cancer and normal lung tissues, the EGFR contents were higher in lung cancer tissues (range: 2.25 to 19.39 pmol·g-1 membrane protein) than that in normal tissues from the same patients (range: 0.72 to 7.43 pmol·g-1 membrane protein). These results suggest that EGF and its receptor may play a role in the regulatory mechanisms in the control of lung cellular growth and tumor promotion

    Patient self-initiated consultations to discuss family history of cancer in primary care and the factors leading to these consultations have not been investigated. Seventy-one out of 150 asymptomatic patients with a family history of cancer at the Yorkshire Cancer Genetics Service participated in this study. A semi-structured questionnaire was administered. The results show that (1) family cancer events, doctors' advice and reaching the age of cancer-affected relatives were more salient in raising awareness of the added cancer risk due to family history than media and publicity, and knowledge of the genetics services; (2) knowledge of family medical history and its clinical value is not easy to ascertain; (3) the inter-relationships with other causal beliefs are of interest and could provide insights to understand the factors motivating patients to discuss family history or cancer risk; (4) the belief that 'cancer runs in the family' or is 'a family thing' may not be sufficient to heighten perceived cancer risk and motivate patients to seek medical advice; and (5) understanding of the medical concept and clinical value of family history is poor even in this group of patients who initiated the GP consultations. In conclusion, because most primary care practitioners are likely to rely on patient initiated discussion to identify individuals at an increased risk of cancer because of their family history, these findings are therefore important to help doctors and health providers understand the reasons influencing asymptomatic patients to self-refer themselves in primary care and discuss cancer risk in order to provide appropriate care.

    The development of cancer is often accompanied by a loss of the primary cilium, a microtubule-based cellular protrusion that functions as a cellular antenna and that puts a break on cell proliferation. Hence, restoration of the primary cilium in cancer cells may represent a novel promising approach to attenuate tumor growth. Using a high content analysis-based approach we screened a library of clinically evaluated compounds and marketed drugs for their ability to restore primary cilium expression in pancreatic ductal cancer cells. A diverse set of 118 compounds stimulating cilium expression was identified. These included glucocorticoids, fibrates and other nuclear receptor modulators, neurotransmitter regulators, ion channel modulators, tyrosine kinase inhibitors, DNA gyrase/topoisomerase inhibitors, antibacterial compounds, protein inhibitors, microtubule modulators, and COX inhibitors. Certain compounds also dramatically affected the length of the cilium. For a selection of compounds (Clofibrate, Gefitinib, Sirolimus, Imexon and Dexamethasone) their ability to restore ciliogenesis was confirmed in a panel of human cancer cell line models representing different cancer types (pancreas, lung, kidney, breast). Most compounds attenuated cell proliferation, at least in part through induction of the primary cilium, as demonstrated by cilium removal using chloral hydrate. These findings reveal that several commonly used drugs restore ciliogenesis in cancer cells, and warrant further investigation of their antineoplastic properties. PMID:26862738

  7. Peritoneal dialysis in Asia.

    The socioeconomic status of Asian countries is diverse, and government reimbursement policies for treatment of patients suffering from end-stage renal disease (ESRD) vary greatly from one country to another. Both of these factors have a major impact not only on the choice of treatment for ESRD but also on the utilization of peritoneal dialysis (PD) in this region. Based on the data collected from 11 representative Asian countries, several observations can be made. First, the treatment rates for ESRD in these countries correlated closely with their gross domestic product (GDP) per capita income. Second, the PD utilization rate appeared to have a biphasic relationship with the GDP per capita income and treatment rate, in that countries with the highest and the lowest treatment rates tended to have lower PD utilization rates, whereas countries with modest treatment rates tended to have higher PD utilization rates. The reason for low PD utilization in countries with the highest treatment rates differs from that in countries with low treatment rates. In the former, because of full government reimbursement, there is little physician incentive to introduce PD as an alternative form of ESRD treatment to in-center hemodialysis (HD), whereas in the latter, the complete lack of government reimbursement prevents the introduction of PD as a form of treatment. This pattern is likely to change in the future because, of the 11 countries surveyed, all except Thailand have recorded a growth rate which is higher for PD than HD over the last three years. The rate of utilization of different PD systems varies greatly among different Asian countries. Automated PD has yet to gain popularity in Asia. Conventional straight-line systems remain the dominant PD systems in use in Hong Kong, Korea, Thailand, and the Philippines, while in Malaysia and Singapore UV germicidal connection devices are most popular. However, in all these countries there has been a progressive shift over the last

    Full Text Available A lumbar peritoneal (LP shunt is a technique of cerebrospinal fluid (CSF diversion from the lumbar thecal sac to the peritoneal cavity. It is indicated under a large number of conditions such as communicating hydrocephalus, idiopathic intracranial hypertension, normal pressure hydrocephalus, spinal and cranial CSF leaks, pseudomeningoceles, slit ventricle syndrome, growing skull fractures which are difficult to treat by conventional methods (when dural defect extends deep in the cranial base or across venous sinuses and in recurrent cases after conventional surgery, raised intracranial pressure following chronic meningitis, persistent bulging of craniotomy site after operations for intracranial tumors or head trauma, syringomyelia and failed endoscopic third ventriculostomy with a patent stoma. In spite of the large number of indications of this shunt and being reasonably good, safe, and effective, very few reports about the LP shunt exist in the literature. This procedure did not get its due importance due to some initial negative reports. This review article is based on search on Google and PubMed. This article is aimed to review indications, complications, results, and comparison of the LP shunt with the commonly practiced ventriculoperitoneal (VP shunt. Shunt blocks, infections, CSF leaks, overdrainage and acquired Chiari malformation (ACM are some of the complications of the LP shunt. Early diagnosis of overdrainage complications and ACM as well as timely appropriate treatment especially by programmable shunts could decrease morbidity. Majority of recent reports suggest that a LP shunt is a better alternative to the VP shunt in communicating hydrocephalus. It has an advantage over the VP shunt of being completely extracranial and can be used under conditions other than hydrocephalus when the ventricles are normal sized or chinked. More publications are required to establish its usefulness in the treatment of wide variety of indications.

    Full Text Available Acinetobacter species are assuming an increasingly important role in modern medicine, with their persistent presence in health-care settings and antibiotic resistance. However, clinical reports addressing this issue in patients with peritoneal dialysis (PD peritonitis are rare.All PD peritonitis episodes caused by Acinetobacter that occurred between 1985 and 2012 at a single centre were retrospectively reviewed. Clinical features, microbiological data, and outcomes were analysed, with stratifications based upon temporal periods (before and after 2000.Acinetobacter species were responsible for 26 PD peritonitis episodes (3.5% of all episodes in 25 patients. A. baumannii was the most common pathogen (54%, followed by A. iwoffii (35%, with the former being predominant after 2000. Significantly more episodes resulted from breaks in exchange sterility after 2000, while those from exit site infections decreased (P = 0.01. The interval between the last and current peritonitis episodes lengthened significantly after 2000 (5 vs. 13.6 months; P = 0.05. All the isolates were susceptible to cefepime, fluoroquinolone, and aminoglycosides, with a low ceftazidime resistance rate (16%. Nearly half of the patients (46% required hospitalisation for their Acinetobacter PD-associated peritonitis, and 27% required an antibiotic switch. The overall outcome was fair, with no mortality and a 12% technique failure rate, without obvious interval differences.The temporal change in the microbiology and origin of Acinetobacter PD-associated peritonitis in our cohort suggested an important evolutional trend. Appropriate measures, including technique re-education and sterility maintenance, should be taken to decrease the Acinetobacter peritonitis incidence in PD patients.

    The purposes of this study are to determine early detection practices performed by primary healthcare professionals, to compare medical and dental sub-groups, and to identify factors that influence the ability of medical and dental practitioners to recognize precancerous changes and clinical signs of oral cancer. A 28-item survey instrument was used to interview a total of 330 Jordanian primary health-care professionals (165 dental and 165 medical). An oral cancer knowledge scale (0 to 31) was generated from correct responses on oral cancer general knowledge. An early detection practice scale (0 to 24) was generated from the reported usage and frequency of procedures in oral cancer examination. Also, a diagnostic ability scale (0 to 100) was generated from correct selections of suspicious oral lesions. Only 17.8 % of the participants reported that they routinely performed oral cancer screening in practices. Their oral cancer knowledge scores ranged from 3 to 31 with a mean of 15.6. The early detection practice scores ranged from 2 to 21 with a mean of 11.6. A significant positive correlation was found between knowledge scores and early detection practice scores (r = 0.22; p oral cancer and oral mucosal lesions are needed for primary health-care professionals.

  12. Primary radiation therapy in the treatment of localized prostatic cancer

    International Nuclear Information System (INIS)

    Prostatic carcinoma is one of the leading causes of male cancer deaths. However, the routine diagnostic and therapeutic strategies have not yet been established. Although the outcome of surgical and radiotherapeutical approaches has frequently been reported to be comparable, the profile of side effects is different. This could offer the basis for selecting the treatment of choice in individual cases. During the last decade the radiotherapeutical technique has markedly improved, in part due to the achievements in the field of computer assisted tomography planning and conformal technique; the outcome of side-effects has decreased with concurrent increase in the rate of local control. The prescribing, recording and reporting of irradiation have also recently developed, as well as the staging of the disease. Therefore we consider it timely to review progress in this subject and to emphasize the role of radiotherapy in the treatment of localized prostatic cancer. (orig.)

    Full Text Available Background. Peritonitis represents a major complication of peritoneal dialysis (PD. The aim of this paper was to systematically collect data on patient-related risk factors for PD-associated peritonitis, to analyze the methodological quality of these studies, and to summarize published evidence on the particular risk factors. Methods. Studies were identified by searches of Pubmed (1990–2012 and assessed for methodological quality by using a modified form of the STROBE criteria. Results. Thirty-five methodologically acceptable studies were identified. The following nonmodifiable risk factors were considered valid and were associated with an increased risk of peritonitis: ethnicity, female gender, chronic lung disease, coronary artery disease, congestive heart failure, cardiovascular disease, hypertension, antihepatitis C virus antibody positivity, diabetes mellitus, lupus nephritis or glomerulonephritis as underlying renal disease, and no residual renal function. We also identified the following modifiable, valid risk factors for peritonitis: malnutrition, overweight, smoking, immunosuppression, no use of oral active vitamin D, psychosocial factors, low socioeconomic status, PD against patient’s choice, and haemodialysis as former modality. Discussion. Modifiable and nonmodifiable risk factors analyzed in this paper might serve as a basis to improve patient care in peritoneal dialysis.

    Penile cancer is a rare neoplasm in the developed world. Clinical assessment often results in inaccurate staging and radiological techniques have a key role in staging and postoperative assessment. Magnetic resonance imaging (MRI) depicts penile anatomy in detail and is the most accurate technique for local staging and postoperative follow-up. MRI and ultrasound (US), although helpful for assessment of lymph nodes, are not reliable enough for accurate nodal staging. US-guided fine needle aspiration cytology (FNAC), however, remains a valuable tool to confirm metastases in suspicious inguinal nodes. Lymphoscintigraphy with dynamic sentinel node biopsy (DSNB) is a promising technique used to predict occult lymph node metastases. Novel imaging techniques such as positron emission tomography/computed tomography (PET-CT) and nanoparticle enhanced MRI have high sensitivity and specificity for lymph node metastases but their availability is limited and clinical utility is not fully established. The radiologist needs to be familiar with the normal penile anatomy, imaging appearances of pre- and post-treatment penile cancer, and the advantages and limitations of the available imaging techniques. This review highlights the above points and presents a systematic approach to make the best use of imaging in the management of patients with penile cancer. (orig.)

    The importance of cancer-associated fibroblasts (CAFs) in cancer biology has been recently highlighted owing to their critical roles in cancer growth, progression, metastasis, and therapeutic resistance. We have previously established a primary culture of breast cancer cells, which showed epithelial-mesenchymal transition and cancer stem cell-like properties. In this study, we found that the primary culture also showed CAF-like properties. For example, hypoxia inducible factor 1α (HIF1A) and its downstream genes, nuclear factor-kappa B2 (NF-κB2) and BCL2/adenovirus E1B 19 kd-interacting protein 3 (BNIP3), and many enzymes involved in glycolysis, such as GAPDH, LDH, PGAM1, and PKM2, were highly overexpressed in the primary culture. Moreover, media conditioned with the primary culture cells enhanced the growth of breast cancer cells. Similar to previous CAF studies, this enhancement suggested to be occurred through fibroblast growth factor signaling. This MCKH primary culture cell, which showed simultaneous expression of tumorigenic and CAF properties, offers a unique experimental system for studying the biology of CAFs.

  19. Second primary cancers in survivors of cervical cancer in the Netherlands: Implications for prevention and surveillance

    International Nuclear Information System (INIS)

    Background and purpose: We investigated the effects of socio-demographic, treatment- and tumor-specific determinants on the risk of developing a second malignancy among patients treated for cervical cancer. Material and methods: We included patients with a first cervical cancer (N = 12,048) from the Netherlands Cancer Registry (NCR), 1989–2008. Standardized incidence ratios (SIR) and absolute excess risks (AER) per 10,000 person-years were calculated to estimate the burden of second cancers in cervical cancer survivors. Incidence rate ratios (IRR) were computed to identify predictors for second cancers among cervical cancer survivors. Results: During the study period, 676 (5.6%) patients were diagnosed with a second cancer. Smoking-related cancers contributed the most to the overall burden of second cancers (AER = 21) and risks remained elevated after 10 years of follow-up (SIR = 1.8, 95% CI: 1.4–2.2), yet it decreased markedly in the younger birth cohorts. Cervical cancer survivors who underwent radiotherapy were at higher risk for a second tumor when compared to those without radiotherapy, especially at smoking-related sites (IRR = 1.6 (1.2–2.3)). Conclusion: Patients with cervical cancer had a significantly increased risk for a second cancer compared to the general population, especially for smoking- and irradiation-related tumors. Long-term follow-up suggested the importance of smoking cessation and the benefits of counseling cervical cancer patients accordingly, particularly those who received radiotherapy

  1. PET-CT detection rate of primary breast cancer lesions. Correlation with the clinicopathological factors

    International Nuclear Information System (INIS)

    One hundred and forty lesions of primary breast cancer underwent positron emission tomography (PET)-CT between June 2006 and May 2007. The PET-CT detection rate of primary breast cancer lesions was 72.1%. The detection rate was 52.1% for invasive cancer ≤20 mm, 92.8% for invasive breast cancers >20 mm, and these results were significant. In the present study, no significant relationship was observed between tumor types, however, invasive lobular carcinoma showed a lower detection rate, 58.3%. The PET-CT results were not significantly affected by either estrogen and progesterone receptors or distant metastasis. A significant correlation regarding the detection rate of PET-CT was found with HER2 status, tumor grade, and axillary lymph node status. The detection rate was 100% for invasive cancer ≤20 mm when the interval between prior diagnostic Mammotome biopsies and PET-CT was less than 3 weeks, 18.8% for invasive cancer ≤20 mm when the interval was more than 3 weeks, and these results were significant. Mammotome biopsies may therefore affect the detection rate of PET-CT. Invasive cancers ≤20 mm showed a low detection rate, therefore, it is considered to be insufficient to use PET-CT for the detection of early breast cancer. (author)

    Peritoneal dialysis (PD) has been extensively used over the past years as a method of kidney replacement therapy for patients with end stage renal disease (ESRD). In an attempt to better understand the properties of the peritoneal membrane and the mechanisms involved in major complications associated with PD, such as inflammation, peritonitis and peritoneal injury, both in vivo and ex vivo animal models have been used. The aim of the present review is to briefly describe the animal models that have been used, and comment on the main problems encountered while working with these models. Moreover, the differences characterizing these animal models, as well as, the differences with humans are highlighted. Finally, it is suggested that the use of standardized protocols is a necessity in order to take full advantage of animal models, extrapolate their results in humans, overcome the problems related to PD and help promote its use.

    Objective: To investigate the effects of neoadjuvant chemotherapy on the expression of drug resistance genes,multidrug resistance-1 (MDR1) and multidrug resistance-associated protein (MRP), in patients with primary breast cancer. Methods: MDR1 and MRP expression were detected by semi-quantitative RT-PCR in 20 patients with primary breast cancer, before and after chemotherapy.Results: Before chemotherapy, MDR1 and MRP expression can be detected in 15 cases (75%) and 18 cases (90%)respectively. After chemotherapy, expression of MDR1 is not significantly different from that before chemotherapy, but expression of MRP is significantly different from that before chemotherapy. Conclusion: Expression of drug resistance gene MRP, but not MDR1, is enhanced in patients with primary breast cancer submitted to neoadjuvant chemotherapy.

    Of 1,486,984 new cancers registered in the Czech Cancer Registry in 1976-2005, 290,312 (19.5%) were multiple malignant neoplasms (MMNs), of which there were 65,292 primary and 89,796 subsequent cases in men and 59,970 primary and 75,254 subsequent cases in women. The duplicities were higher in women, and the triplicities and others (3–6 MMNs) were higher in men. The most frequent diagnoses were the primary cancers of skin, gastrointestinal and urinary tract, male genital organs, respiratory tract in men, and cancers of skin, breast, female genital organs, and gastrointestinal tract in women. The analysis of the early and advanced clinical stages shows that the number of subsequent advanced stages increased after primary advanced stages. Their time-age-space distributions visualized maps of MMNs in 14 Czech regions. These results support the improvement of algorithms of dispensary care for the early detection of the subsequent neoplasms. PMID:23936674

    Full Text Available Renal squamous cell cancer is one of the rare primary urothelial tumors with only a handful of cases reported in literature. Because of high grade, advanced and late presentation, they herald a grave prognosis. They are frequently associated with calculus disease, smoking, phenacetin consumption and foci of squamous metaplasia due to chronic irritation. Nephroureterectomy is the treatment of choice for such tumors. We hereby present a case of 59 year old female who presented with squamous cell cancer of renal pelvis.

    Spontaneous bacterial peritonitis is caused by infection of ascitic fluid without any apparent intraabdominal source of infection. The disease most commonly occurs in patients with cirrhosis and 70% of cases of infections are caused by pathogenes from gastrointestinal tract. The article presents the case of 38-year-old patient with spontaneous peritonitis who was treated surgically. The primary nature of the disease was confirmed by laparotomy and bacteriological examination results (Streptoccocus pneumonia) of ascitic fluid. After 54 days of hospitalisation and undergoing re-laparotomy, he was discharged in good condition. PMID:22166482

    2013-04-01

    Full Text Available Background: Cancer diagnosis has a significant impact not only on women, but also on their Primary caregivers. Understanding the effects of a breast cancer diagnosis on physical and mental health outcomes in caregivers is important because these variables are key components of quality of life. Quality of life is a multi-dimensionalconstruct measuring overall enjoyment of life. This study intends to describe the impact of caring for women with breast cancer on the quality of life among their primary caregivers.Method: We conducted a comprehensive search in PubMed, MEDLINE andCINAHL. In addition, we used the web search engine “Google” for abstracts from 2007 to 2012. A total of eight studies were reviewed that met the following inclusion criteria: adult women with breast cancer, research conducted in English. Studies ranged from 2007-2011. The total sample size in the eight studies on adult caregivers totaled 789 participants. The average age of participants in all of the studies was 49.55 years.There were seven studies that had a quantitative focus,which mainly used a questionnaire and survey to estimate quality of life among primary caregivers. The qualitative approach included in-depth interviews and a focus group.Results: Accumulating evidence has supported the concept that cancer affects not only the patients but also their primary caregiver's quality of life.They face multiple challenges in caring for women with breast cancer, including physical, emotional, social, and financial stress that affects the caregiver's quality of life.Conclusion: Breast cancer diagnosis not only affects the patient's quality of life, but in parallel, also affects the quality of life of the primary caregiver. Thus more focus should be placed on providing moral and social support, and educational resources to improve the level of the caretaker's quality of life.

  4. “Unique trend” and “contradictory trend” in discrimination of primary synchronous lung cancer and metastatic lung cancer

    International Nuclear Information System (INIS)

    Distinguishing between multiple primary lung cancers and metastatic tumors is often difficult when the tumor histology is same. Since genomic instability is a common feature of cancer, we hypothesized that independently arising neoplasms in an individual patient would exhibit measurable genomic variation, enabling discrimination of tumor lineage and relatedness. The feasibility of analyzing genomic instability expression profiles to distinguish multiple primary lung cancers from metastatic tumors was evaluated. This study enrolled 13 patients, with multiple primary lung cancers demonstrating with the histology, who underwent surgery between April 2003 and December 2012 at the Department of the Thoracic Surgery at West China Hospital in Sichuan province of China and 10 patients who were diagnosed as metastasis disease during the same period for comparison purposes. Genomic DNA from lung cancers from individual patients was analyzed by six microsatellites (D2S1363, D6S1056, D7S1824, D10S1239, D15S822, and D22S689) with PCR to identify discordant allelic variation. The experiments were approved by the West China Hospital Ethics committee (No.2013 (33)) and all patients agreed to participate in the study and signed an informed consent form. All of the 10 patients with distant metastasis showed a consistent consequence that we called “unique trend” between primary tumor and distant metastasis. The “trend” is representive in this study, which means that all alleles corresponding to six microsatellite markers were detected in DNA from primary tumors but were reduced or not observed in DNA from metastatic tumors. In the group of synchronous lung tumor with different histological types, the result showed a “contradictory trend”. Some alleles were detected in DNA from primary tumors but were reduced or not observed in DNA from metastatic tumors and other alleles corresponding to six microsatellite markers were detected in DNA from metastatic tumors but were

  6. Transarterial chemoembolisation and radioembolisation for the treatment of primary liver cancer and secondary liver cancer: a review of the literature

    International Nuclear Information System (INIS)

    Liver-directed therapies are continuing to evolve in the field of interventional oncology and are gaining increasing use in the treatment of unresectable primary and secondary liver cancers. In this article, we review two liver-directed therapies that are currently used for the palliative treatment of primary and secondary hepatic tumours: transcatheter arterial chemoembolisation (TACE), including a new type of TACE with drug-eluting beads (DEB-TACE), and radioembolisation. The concept of these transcatheter intraarterial therapies is to selectively deliver high doses of anticancer treatment to the tumour. While TACE delivers one or more chemotherapeutic drugs into the hepatic arteries supplying the tumour, radioembolisation uses non-embolic microspheres incorporating the radioactive isotope 90Y. In this article, we discuss some technical aspects, patient selection, current clinical evidence, and future directions of TACE, TACE with drug-eluting beads (DEB-TACE) and radioembolisation for primary and secondary liver cancer.

    Full Text Available Metastatic carcinomas of unknown primary origin (cancer of unknown primary-CUP represent 3-5% of all cancers. This term includes all patients presented with metastatic disease in whom the primary site could not have been identified. Despite the use of modern and comprehensive diagnostic techniques and procedures, there is no improvement in efficacy (efficiency of indentifying the primary site of disseminated disease. That is why a diagnostic procedure should be rational and should include the basic diagnostic examination (analyses with the aim to define biological and clinical characteristics of diagnosed disease, as well as an optimal therapeutic approach. Although the overall prognosis of the majority of these patients is poor, it is possible, nowadays, to distinguish the subgroups of patients with favorable prognosis. Results of new basic research, better understanding of pathogenesis at the molecular level and introduction of new drugs through clinical trials suggest an advance in this disease treatment and outcome.

    Full Text Available Introducción: Valorar si el descanso peritoneal, de al menos un día semanal, ha supuesto mejoras en la rehabilitación de los pacientes y el impacto clínico que puede suponer. Nos planteamos además cuantificar el beneficio económico. Material y Método: Se realizó un estudio longitudinal, retrospectivo, descriptivo. De los pacientes atendidos en nuestra unidad desde el 1 de enero de 2014 al 31 de diciembre de 2014, se estudiaron los pacientes que cumplieran todo el año de seguimiento y que no procedieran de otras técnicas de depuración como la hemodiálisis o trasplante renal. La muestra de estudio estuvo compuesta por 40 pacientes, de los que 21 tuvieron prescrito al menos 1 día semanal de descanso peritoneal y 19 pacientes sin descanso. Se recogieron las siguientes variables al inicio del periodo de estudio y a los 12 meses: Variables demográficas, variables relacionadas con el estado de volumen, datos clínicos relacionados con la técnica, se pasó una encuesta de satisfacción a todos los pacientes estudiados, y se recogieron los importes del coste mensual de cada tipo de tratamiento. Resultados: Las diferencias iniciales entre los grupos, eran esperables ya que son los valores en los cuales se ha basado la prescripción del día de descanso. La exposición a la glucosa, al comienzo y al final fue menor en el grupo con descanso. Al año, no se encontró diferencias en los parámetros estudiados. Una encuesta de satisfacción nos reveló a que dedican los pacientes el día de descanso y los que no lo tienen a que lo dedicarían. Conclusiones: El descanso peritoneal no ha supuesto una peor evolución de los parámetros clínicos estudiados al año de seguimiento, cumpliendo las recomendaciones de adecuación de diálisis de las guías clínicas. La exposición a la glucosa, aun sin llegar a ser significativa por la duración del estudio, ha sido menor en el grupo con descanso. El día de descanso ha facilitado a los pacientes

    2015-01-01

    Hepatocellular carcinoma (HCC) is a primary malignancy of the liver with poor prognosis and limited therapeutic options. Over the past few years, many studies have evaluated the role of non-coding RNAs (ncRNAs) in hepatocarcinogenesis and tumor progression. ncRNAs were shown to have diagnostic, prognostic, and therapeutic potential in HCC. In this manuscript, we review the latest major discoveries concerning microRNAs and long ncRNAs in HCC pathogenesis, and discuss the potentials and the limitations for their use in clinical practice.

    Early detection and diagnosis of cancers is extremely beneficial for improving the survival rate of cancer patients and molecular imaging techniques are believed to be relevant for offering clinical solutions. Towards early cancer detection, we developed a primary animal colorectal cancer model and constructed a tumor-specific imaging probe by using biocompatible NaGdF4:Yb,Er@NaGdF4 upconversion luminescent NPs for establishing a sensitive early tumor imaging method. The primary animal tumor model, which can better mimic the human colorectal cancer, was built upon continual administration of 1,2-dimethylhydrazine in Kunming mice and the tumor development was carefully monitored through histopathological and immunohistochemical analyses to reveal the pathophysiological processes and molecular features of the cancer microenvironment. The upconversion imaging probe was constructed through covalent coupling of PEGylated core-shell NPs with folic acid whose receptor is highly expressed in the primary tumors. Upon 980 nm laser excitation, the primary colorectal tumors in the complex abdominal environment were sensitively imaged owing to the ultralow background of the upconversion luminescence and the high tumor-targeting specificity of the nanoprobe. We believe that the current studies provide a highly effective and potential approach for early colorectal cancer diagnosis and tumor surgical navigation.Early detection and diagnosis of cancers is extremely beneficial for improving the survival rate of cancer patients and molecular imaging techniques are believed to be relevant for offering clinical solutions.

  14. Second primary malignant neoplasm following radiation therapy for head and neck cancer

    International Nuclear Information System (INIS)

    This retrospective analysis reports the results of radiotherapy in 8272 patients with cancer who were treated at Tokyo Women's Medical College between 1966 and 1984. One thousand one hundred and four cases were irradiated for head and neck tumor during this period. Twenty-nine of the total number of patients (0.35 %) were found to have second primary malignant neoplasms following radiotherapy according to the criteria of radiation-induced or related cancers. Twenty of these were head and neck tumors with an incidence of 1.81 % among all head and neck cancer patients. If recurrence of highly suspected cases was excluded, the incidence of radiation-induced or -related cancer was 0.18 % among all malignancies and 0.63 % among all head and neck tumors. Cases of multiple primary malignant neoplasm have been increasing in number and second cancer following radiotherapy has gradually become a big problem. However, the mechanisms of cancer etiology on which radiation and many other factors have an influence are not clear at this time, as there are many risks to human life. It is important not to underestimate the value of radiotherapy in cancer treatment today. (author)

  15. Evaluation of Primary Prevention of Skin Cancer: A UK Perspective

    International Nuclear Information System (INIS)

    Good quality research to study behaviour in the sun is needed in the UK to ensure that we can develop the most effective methods for ultimately reducing the incidence of skin cancer. Many initiatives have taken place during the past two decades to reduce the level of sun exposure. However, there have been relatively few studies to evaluate the impact of these initiatives on behaviour and health. This review summarises outcome measures of knowledge, attitudes, and behaviour and of clinical signs of sun damage. The results of evaluation studies show that adolescents are a group resistant to change. Initiatives should focus on families with young children. Targeting holiday makers at the time of departure also proved to be ineffective. Future research should aim to monitor changes in behaviour in the general population, and to study changes among target groups using standardised methods. The costs of different interventions should be compared. (author)

  16. Efficacy of stereotactic radiotherapy for primary and metastatic liver cancer

    International Nuclear Information System (INIS)

    Twenty patients (30 nodules) with metastatic liver cancer (MLC) and 10 cases with hepatocellular carcinoma (HCC) treated by stereotactic radiotherapy (SRT) were analyzed. SRT was administered at 48.0 or 52.8 Gy/4 Fr/1 wk. The response rate (RR) in MLC patients was 78%, and 11 patients survived longer than 1 year and 9 patients survived as long as 2 years. Clinical analysis suggests that the ideal indications for SRT in MLC are solitary nodules in patients without extrahepatic disease who have undergone systemic chemotherapy. Although RR of SRT for HCC was as high as 85%, intrahepatic recurrence was observed in all patients and 6 patients died within 1 year Further analysis is needed to determine the indication for SRT in HCC patients.

  17. Is palliative resection of the primary tumour, in the presence of advanced rectal cancer, a safe and useful technique for symptom control?

    International Nuclear Information System (INIS)

    Over an 8-year period 22 patients (average age 54 years) underwent rectal resectional surgery in the presence of metastatic disease. There were 13 men and nine women. The commonest complaint was rectal bleeding. All patients had chest radiographs. Pulmonary metastases were identified in four patients. Nineteen abdominal and pelvic computed tomography scans were performed and eight showed evidence of metastases. Skeletal radiographs in two patients showed evidence of bone metastasis. At operation, intraperitoneal metastases were found in 18 patients. Nine of these were not identified preoperatively. Six patients underwent abdomino-perineal resection, nine anterior resection and seven a Hartmann's procedure. Eight patients developed a significant postoperative complication and one died 42 days after surgery. The mean length of hospital stay was 18.6 days. Nine patients received preoperative radiotherapy. Four patients had palliative radiotherapy, two for bony, one for liver and one for peritoneal metastases. Patients were followed up for a mean of 1.1 years. During follow up, 11 returned to the emergency room on 24 occasions. Two patients required readmission. No patient had further rectal bleeding. The mean survival was 1.3 years. It is concluded that patients with rectal cancer and unresectable distant metastases can be successfully palliated by resection of the primary tumour with low morbidity and mortality. The early involvement of a palliative care team facilitates patient management and helps patients enjoy what remains of the rest of their lives at home, in comfort and with good symptom control.

  18. Primary (recurrent) and metastatic lesions detection in cervical cancer: A comparison of positron emission tomography, CT and/or MRI image and pathological study

    International Nuclear Information System (INIS)

    Aim: This prospective study is to compare the results of primary (recurrence) and metastatic lesions detection, based on pathologic results, with computed tomography (CT) and/or magnetic resonance imaging (MRI) and positron emission tomography (PET) with [18F]-fluoro-2-deoxy-D-glucose (FDG) in invasive cervical cancer (ICC). Materials and Methods: An FDG PET scan was performed in 136 patients with ICC (107 squamous cell carcinoma [SCC], 18 adenocarcinoma [AdenoCa], 5 adeosquamous cell carcinoma, 4 small cell carcinoma, and 2 poorly differentiated carcinoma; from FIGO staging IB to IVB prior to operation). CT and/or MRI image were performed within one week before or after FDG PET scan was done. The accuracy of lymph node status was based on histological result or a second FDG PET combined with a CT and/or MRI image images. Results: Totally, 68 main tumor and 147 metastatic lesions were recognized by either histopathology or a follow up study. On a lesion basis, CT and/or MRI image images demonstrated 63 (92.6 %) main tumor and 103 (70.1 %) metastatic lesions. For lymph node metastatic lesions detection, there were 6(75 %) enlarged inguinal lymph nodes, 38(76 %) enlarged pelvic lymph nodes (PLN), 28(73.7 %) enlarged para-aortic lymph nodes (PAN), 8(50 %) enlarged supraclavicular lymph nodes (SLNs), and 5(62.5 %) enlarged mediastinal lymph nodes (MLNs). Liver metastases were found in 4(100 %), in lung in 7(70 %) and in bone in 5(83.3 %). Peritoneal metastases were found in 2(28.6 %). FDG PET demonstrated 63 (92.6 %) and 135 (91.8 %) metastatic lesions. For lymph node metastases, FDG PET found 8(100 %) enlarged inguinal lymph nodes, 44(88 %) enlarged PLNs, 36(94.7 %) enlarged PANs, 15(93.8 %) enlarged SLNs, and 8(100 %) enlarged MLNs. Liver metastases were found in 4(100 %), in lung in 9(90 %) and in bone in 6(100 %). Peritoneal metastases were found in 5(71.4 %). On a patient basis, with FDG PET scan, 31(22.8%) were upstaging while 4(2.9%) were down staging. 35

  19. Spontaneous bacterial peritonitis

    2009-01-01

    Since its initial description in 1964, research has transformed spontaneous bacterial peritonitis (SBP) from a feared disease (with reported mortality of 90%) to a treatable complication of decompensated cirrhosis,albeit with steady prevalence and a high recurrence rate. Bacterial translocation, the key mechanism in the pathogenesis of SBP, is only possible because of the concurrent failure of defensive mechanisms in cirrhosis.Variants of SBP should be treated. Leucocyte esterase reagent strips have managed to shorten the 'tap-toshot' time, while future studies should look into their combined use with ascitic fluid pH. Third generation cephalosporins are the antibiotic of choice because they have a number of advantages. Renal dysfunction has been shown to be an independent predictor of mortality in patients with SBP. Albumin is felt to reduce the risk of renal impairment by improving effective intravascular volume, and by helping to bind proinflammatory molecules. Following a single episode of SBP, patients should have long-term antibiotic prophylaxis and be considered for liver transplantation.

    Full Text Available BACKGROUND: Cancer surivors have limited knowledge about second primary cancer (SPC screening and suboptimal rates of completion of screening practices for SPC. Our objective was to test the efficacy of an educational material on the knowledge, attitudes, and screening practices for SPC among cancer survivors. METHODS: Randomized, controlled trial among 326 cancer survivors from 6 oncology care outpatient clinics in Korea. Patients were randomized to an intervention or an attention control group. The intervention was a photo-novel, culturally tailored to increase knowledge about SPC screening. Knowledge and attitudes regarding SPC screening were assessed two weeks after the intervention, and screening practices were assessed after one year. RESULTS: At two weeks post-intervention, the average knowledge score was significantly higher in the intervention compared to the control group (0.81 vs. 0.75, P<0.01, with no significant difference in their attitude scores (2.64 vs. 2.57, P = 0.18. After 1 year of follow-up, the completion rate of all appropriate cancer screening was 47.2% in both intervention and control groups. CONCLUSION: While the educational material was effective for increasing knowledge of SPC screening, it did not promote cancer screening practice among cancer survivors. More effective interventions are needed to increase SPC screening rates in this population. TRIAL REGISTRATION: ClinicalTrial.gov NCT00948337.

    2013-01-01

    Full Text Available Background/Aim: Peritoneal carcinomatosis (PC is a pernicious event associated with a dismal prognosis. Complete cytoreductive surgery (CCRS combined with hyperthermic intraperitoneal chemotherapy (HIPEC is able to yield an important survival benefit but at the price of a risky procedure inducing potentially severe complications. Postoperative peritonitis after abdominal surgery occurs mostly when the digestive lumen and the peritoneum communicate but in rare situation, no underlying digestive fistula can be found. The aim of this study was to report this situation after CCRS plus HIPEC, which has not been described yet and for which the treatment is not yet well defined. Patients and Methods: Between 1994 and 2012, 607 patients underwent CCRS plus HIPEC in our tertiary care center and were retrospectively analyzed. Results: Among 52 patients (9% reoperated for postoperative peritonitis, no digestive fistula was found in seven (1%. All had a malignant peritoneal pseudomyxoma with an extensive disease (median Peritoneal Cancer Index: 27. The median interval between surgery and reoperation was 8 days [range: 3-25]. Postoperative mortality was 14%. Five different bacteriological species were identified in intraoperative samples, most frequently Escherichia coli (71%. The infection was monobacterial in 71%, with multidrug resistant germs in 78%. Conclusions: Postoperative peritonitis without underlying fistula after CCRS plus HIPEC is a rare entity probably related to bacterial translocation, which occurs in patients with extensive peritoneal disease requiring aggressive surgeries. The principles of treatment do not differ from that of other types of postoperative peritonitis.

    PURPOSE We encountered a case where an infection with group A streptococcus (GAS; ie, Streptococcus pyogenes) initially caused primary peritonitis and then subsequently caused streptococcal toxic shock syndrome. The patient’s life was likely saved by an emergency laparotomy followed by extensive peritoneal lavage and drainage. CASE PRESENTATION A 40-year-old woman was admitted to the Emergency Department for lower abdominal pain and numbness in the extremities. She presented with systemic inflammatory response syndrome. An emergency laparotomy was performed, and ascites that resembled pus and general peritonitis were noted. Peritoneal lavage and drainage were performed, and GAS was isolated from peritoneal fluid. Gram staining of cervical polyp specimens revealed Gram-positive bacteria. CONCLUSIONS The patient was diagnosed with streptococcal toxic shock syndrome due to an ascending GAS infection originating from vagina.

    This study was based on the data collected through personal interviews by the Yang-Ming Crusade, organized by students of National Yang-Ming Medical College, during the summer vacations in 1983-1985. Arranged by 21 city/country Education Bureaus, the crusaders gave lectures on cancer education for primary school teachers in every city and town throughout the Taiwan area. Totally 36,426 questionnaires were filled out before the lecture meetings. This is a KAP (knowledge, attitude and practice) study of cancer prevention among primary school teachers. The cognizance rates of cervical cancer as the leading cancer and as the most curable one for women in Taiwan were 75.5% and 43.0% respectively. Pap smear and Hemoccult Slide Test were known by 95.9% and 74.0% of the interviewees, mostly from TV (65.6% and 68.9%), followed by hospital and others. The necessity of "early diagnosis and early treatment" was accepted by 91.9% of the interviewees, a periodical check-up for cancer was thought essential by 93.4% of them, and cancer insurance was consent by 90.3% of them. It was agreed by 51.3% of the interviewees and disagreed by 46.7% of them that herbs are effective to cure cancer. Psychological fear (36.8%), physiological pain (30.2%) and worry of interfering family (15.3%) were considered the most dreadful situations by primary school teachers in case of having cancer. Totally 56.4% of the female interviewees had had a Pap Test, 63.8% of them were for prevention. The most frequently consulted person for a Pap Test was husband (30.1%) and, secondly herself (8.0%). The most influencial persons for having a Pap Test were husband (24.8%) and physician (11.1%).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1646677

    2014-08-01

    Locally ablative therapies have an increasing role in the effective multidisciplinary approach towards the treatment of both primary and metastatic liver tumors. In patients who are not considered surgical candidates and have low volume disease, these therapies have now become established into consensus practice guidelines. A large range of therapeutic options exist including percutaneous ethanol injection (PEI), radiofrequency ablation (RFA), microwave ablation (MWA), cryoablation, percutaneous laser ablation (PLA), irreversible electroporation (IRE), stereotactic body radiation therapy (SBRT) and high intensity focused ultrasound (HIFU); each having benefits and drawbacks. The greatest body of evidence supporting clinical utility in the liver currently exists for RFA, with PEI having fallen out of favor. MWA, IRE, SBRT and HIFU are relatively nascent technologies, and outcomes data supporting their use is promising. Future directions of ablative therapies include tandem approaches to improve efficacy in the treatment of liver tumors. PMID:24746315

    2002-09-01

    The peritoneal carcinomatosis is considered an unlikely treatable disease using standard procedures as surgery or systemic chemotherapy. New improvements in the knowledge of the peritoneum are inducing to consider the mesothelium of the abdominal cavity as an organ similar to the other body organs. This new consideration, unified with the understanding of conditions permitting the implant of the tumor cell into the peritoneal space previous or during the surgical manipulation of the abdominal cancers, leads to the application of news strategies as the advanced cytoreduction with every nodes reduced less than 2.5 mm followed by the chemohyperthermic peritoneal perfusion (CHPP). Last papers indicate improvements in overall survival and quality of the life in ovarian, colonic and gastric cancer treated with an extensive surgical debulking plus CHPP. These results induce surgeons and oncologists to avoid incorrect strategies in the treatment of peritoneal carcinomatosis originating from ovarian and gastrointestinal tumors. In case of malignant untreatable ascites a peritoneo-venous shunt allows a control of the ascites avoiding several hospital admissions for continuous fastidious and sometime dangerous paracentesis. A palliative surgical operation in selected patients effected by trained surgical group permits an improvement of the patient's conditions in more than 80% with a positive feed back on his or her psychological behavior.

  8. p53 Mutations and Protein Overexpression in Primary Colorectal Cancer and its Liver Metastasis

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    To compare p53 status in primary and hepatic metastatic colorectal cancer in 34 patients. Methods: p53 gene status (exons 5- 9) was examined by PCR, denaturing gradient gel electrophoresis (DGGE) and automated sequencing. P53 protein was detected by immunohistochemistry using monoclonal antibody DO-7. Results: p53 mutations were found in exons 5 through 9 in 21 of 34 patients (61.8%). Among them, 5 patients had mutation in liver metastasis but not in their primary tumors while in the other patients the same mutations were found in both primary and metastatic colorectal cancers. In no patients was p53 mutation exclusively found in the primary colorectal tumors. Moreover, additional mutation was detected in the metastatic lesions in two cases. Of the 37 mutations within the exons examined, 73% was missense mutation and 16% was nonsense mutation. There were 4 microinsertions. P53 protein was overexpressed in both primary and metastatic colorectal cancers with p53 gene mutations. The presence of p53 mutation significantly correlated with p53 protein accumulation (r=0.96, p< 0.001). However, in 4 patients with p53 nonsense mutation, immunohistochemical staining was negative. In three patients who showed no p53 mutation of the primary tumor, p53 protein was consistently overexpressed. Conclusion: In colorectal cancers, p53 gene mutation usually appears first in the primary tumor and maintains as such but is more prominent when metastasized to the liver. However, p53 gene mutation may occur only after being metastasized.Although p53 gene mutation and p53 protein overexpression correlate with each other, either parameter examined alone may lead to false positive or negative results.

    Purpose Androgen deprivation therapy may increase diabetes risk. As the benefits of primary androgen deprivation therapy for localized prostate cancer are controversial, and most prostate cancer survivors are of advanced age with comorbidities, it is important to determine if primary androgen deprivation therapy increases the risk of diabetes and to determine the susceptibility factors. Materials and Methods We conducted a retrospective cohort study of 12,191 men diagnosed with incident localized prostate cancer during 1995 to 2008, age 35 to 100 years, and without diabetes or receipt of prostatectomy or radiation 1 year after diagnosis. Patients were enrolled in 1 of 3 managed health plans and followed through 2010. Primary androgen deprivation therapy was defined as androgen deprivation therapy within 1 year after diagnosis. Incident diabetes was ascertained using inpatient and outpatient diagnosis codes, diabetes medications and hemoglobin A1c values. We estimated primary androgen deprivation therapy associated diabetes risk using Cox proportional hazard models in conventional and propensity score analyses. Results Diabetes developed in 1,203 (9.9%) patients during followup (median 4.8 years) with incidence rates of 2.5 and 1.6 events per 100 person-years in the primary androgen deprivation therapy and nonprimary androgen deprivation therapy groups, respectively. Primary androgen deprivation therapy was associated with a 1.61-fold increased diabetes risk (95% CI 1.38–1.88). The number needed to harm was 29. The association was stronger in men age 70 or younger than in older men (HR 2.25 vs 1.40, p value for interaction = 0.008). Conclusions Primary androgen deprivation therapy may increase diabetes risk by 60% and should be used with caution when managing localized prostate cancer. Because of the consistent association between androgen deprivation therapy and greater diabetes risk across disease states, we recommend routine screening and lifestyle

    Virotherapy is one of the novel anti-cancer strategies currently being investigated in preclinical experiments and clinical trials to fight cancer. Virotherapy is based on attenuated, replication-competent oncolytic viruses which selectively infect, replicate in and kill tumor cells without significantly harming healthy tissue. To advance the inherited oncolytic effect of viruses, trans¬genes like anti-angiogenic, immuno-stimulatory or suicide genes were inserted into the viral genome. Fo...

  17. Estrogen receptor of primary breast cancers: evidence for intracellular proteolysis

    International Nuclear Information System (INIS)

    Iodinated oestradiol-labeled oestrogen receptor (ER) isoforms devoid of amino-terminal ABC domains represent about two-thirds of the whole receptor population detected in cytosol samples from human breast cancers. This high frequency could not be ascribed to the expression of truncated mRNAs, or to the proteolysis of the native ER peptide at the time of homogenization or assay, suggesting an intracellular proteolysis. Free amino-terminal and ligand-binding domains maintained together within oligomeric structure(s); increase of ionic strength separated them. The amino-terminal region was consistently detected in the cell nucleus by specific immunohistochemistry leading to the concept of a potential intranuclear association between ER cleavage products and/or other regulatory proteins. We previously reported that about two-thirds of [125I]oestradiol-labelled cytosolic ERs from breast cancer samples eluted as low-molecular-weight isoforms (≤ 37 kDa, size-exclusion fast pressure liquid chromatography [FPLC]). These isoforms failed to adsorb strongly to hydroxylapatite at high ionic strength, a property that was ascribed to receptors devoid of amino-terminal ABC domains. In view of recent data concerning intracellular proteolysis of several transcriptional regulators, the possibility of such behaviour for ER was assessed. The clinical significance of ER measurement in breast cancer cytosols is well established; approximately 50% of ER-positive cases respond to endocrine therapy. Whether such a poor correlation is related to a high proportion of cleaved ER is a question of prime importance. Failure of routine ER assays to discriminate between full-length and cleaved receptors led us to develop an oestradiol-binding assay based on hydroxylapatite adsorption. The aims of the present study were to demonstrate that hydroxylapatite adsorption assay easily identifies cleaved cytosolic ER forms and to assess the origin of such ER forms. Breast cancer cytosols classified as ER

    F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET/CT) plays an important role in diagnosis of malignant tumors and adds to conventional imaging in the staging of pertoneal carcinomatosis. However, false positive cases resulting from benign disease such as tuberculosis may occur. We report two cases of peritoneal tuberculosis on F-18 FDG PET/CT which showed multiple hypermetabolic foci in the mesentery and peritoneum with increased serum cancer antigen 125 (CA 125). Subsequent F-18 FDG PET/CT showed a disappearance of pathologic uptake following treatment with anti-tuberculosis drugs.

    Purpose. In this study, we evaluated our experience with salvage brachytherapy after discovery of biochemical recurrence after a prior brachytherapy procedure. Methods and Materials. From 2001 through 2012 twenty-one patients treated by brachytherapy within University of Kentucky or from outside centers developed biochemical failure and had no evidence of metastases. Computed tomography (CT) scans were evaluated; patients who had an underseeded portion of their prostate were considered for reimplantation. Results. The majority of the patients in this study (61.9%) were low risk and median presalvage PSA was 3.49 (range 17.41–1.68). Mean follow-up was 61 months. At last follow-up after reseeding, 11/21 (52.4%) were free of biochemical recurrence. There was a trend towards decreased freedom from biochemical recurrence in low risk patients (p = 0.12). International Prostate Symptom Scores (IPSS) increased at 3-month follow-up visits but decreased and were equivalent to baseline scores at 18 months. Conclusions. Salvage brachytherapy after primary brachytherapy is possible; however, in our experience the side-effect profile after the second brachytherapy procedure was higher than after the first brachytherapy procedure. In this cohort of patients we demonstrate that approximately 50% oncologic control, low risk patients appear to have better outcomes than others. PMID:27092279

    Introduction: This paper reports on an ongoing primary care audit of cancer referrals undertaken in Scotland in 2006–2007 and 2007–2008. Methods: General practitioners (GPs) in Scotland were asked to review all new cancer diagnoses within their practice during the preceding year. Results: 4181 patients were identified in year 1 and 12 294 in year 2. The pathway taken for patients to present to, and be referred from, their GP has been analysed for 7430 of the 12 294 patients identified within year 2 across five separate health boards. The time from first symptoms to presentation to a GP varied between tumour types, being the longest (median 30 days) for head and neck cancers and the shortest (median 2 days) for bladder cancer. In all, 25% of patients within the following tumour groups waited longer than 2 months to present to their GP following first symptoms: prostate, colorectal, melanoma and head and neck cancers. Once patients had presented to their GP, those with prostate and lung cancer were referred later (median time 11 days) than those with breast cancer (median time 2 days). The priority with which GPs referred patients varied considerably between tumour groups (breast cancer 77.5% ‘urgent' compared with prostate cancer 44.7% ‘urgent'). In one health board the proportion of cancer patients being referred urgently increased from 46% to 58% between the first and second audit. Conclusion: Our data show that there are very different patterns of presentation and referral for patients with cancer, with some tumour groups being more likely to be associated with a delayed diagnosis than others.

    Full Text Available BACKGROUND: Increased body mass index is related to the incidence of thyroid cancer. However, the presentation and therapeutic outcomes of different thyroid cancers and type 2 diabetes mellitus (DM have not been studied. This study investigated the effect of type 2 DM on the clinical presentations and therapeutic outcome of well-differentiated thyroid cancer. METHODS AND FINDINGS: A retrospective analysis of adult thyroid cancer patients with or without type 2 DM admitted between January 2001 and December 2010 was performed at an institution. A total of 1,687 well-differentiated thyroid cancer patients with different histological patterns were enrolled. Among these subjects, 122 were type 2 DM patients. Patients with thyroid cancer and type 2 DM were significantly older than non-DM patients. After a mean follow-up period of 5.6±0.1 years, patients with thyroid cancer and type 2 DM showed a higher percentage of disease progression than non-DM patients (24.6% vs. 17.4%. In addition, disease-specific mortality was higher in the type 2 DM group (10.7% vs. 3.8%. Thyroid cancer patients with type 2 DM showed a higher percentage of secondary primary cancers than those without DM (10.7% vs. 4.9%. Thyroid cancer-specific survival rates in the type 2 DM and non-DM groups were 82.2% and 94.9% at 5 years, 72.9% and 91.4% at 10 years, and 36.5% and 61.3% at 20 years, respectively. Multivariate analysis showed that type 2 DM was independent of thyroid cancer-specific mortality. CONCLUSION: Patients with type 2 DM and well-differentiated thyroid cancer had an advanced tumor-node-metastasis stage at the time of diagnosis and an increased disease-specific mortality. Aggressive surgical procedures and close follow-up for well-differentiated thyroid cancer patients with type 2 DM are therefore necessary.

  5. Clinical application of FDG-PET/CT for occult primary cancer

    International Nuclear Information System (INIS)

    The aim of this study was to assess the role of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in the identification of occult primary cancers. The study population consisted of 39 consecutive patients with histologically proven metastatic disease or diagnosed by conventional procedures (CT or MRI). PET/CT imaging was performed in all patients 1 hour after administration of 3.75 MBq/kg of fluorodeoxyglucose with a whole-body field of view. PET/CT detected the occult primary cancer in 31 cases (79.4%), showing higher sensitivity than other reports. PET/CT was able to depict more primary tumors, though not significantly, than either of the other imaging modalities. (author)

    The evaluation of the influence of different environmental carcinogenic factors requires interdisciplinary cooperation. Related studies include epidemiological surveys and air, water and soil, chemical, toxicological, and microbiological analyses, supplemented by experimental verification of suspected ecological pathogens and cofactors. A balance of carcinogens and protective agents in the external environment and in the human body is recommended for an ecologically oriented prevention. Toxicological control of the food chain using modern technology (Proton-induced X-ray emission (PIXE), nuclear activation analysis, and induced coupled plasma) should be integrated with microanalyses at the cellular level (by X-ray scanning electron microscopy, nuclear magnetic response, PIXE, and spontaneous and delayed chemiluminescence for balance of free-radicals and their scavengers). A pilot cross-disciplinary study conducted in the area of a "cluster" of human neoplasms and cattle leukemia, in comparison with control villages in Poland, showed an excess in Pb, Hg, Ni, Rb, K, Mn, Cr, and Zn, accompanied by a nutritional deficiency in Mg, Ca, Fe, Co, and Se in the food chain of the "cluster." The living and breeding houses in this area were significantly more contaminated with the toxicogenic molds Aspergillus flavus and Penicillium meleagrinum and by nitrate and nitrite in the drinking water. Our experiments showed that selenium deficiency stimulated the growth of fungi and some bacteria and increased the immunosuppressive and teratogenic effects of aflatoxin B1. New methods of protection of the indoor environment against microbiological contamination and laser-related biotechnology for nutritional prevention of selenium deficiency and associated risk of neoplasms have been introduced. Primary prevention requires a large scale application of highly sensitive methods for early detection of risk factors in the environment, food, water, and at the personal level, as well as

  10. PET with [18F]fluorothymidine for imaging of primary breast cancer: a pilot study

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the use of [18F]fluorothymidine (FLT) as a positron emission tomography (PET) tracer for the diagnosis of breast cancer. To this end, 12 patients with 14 primary breast cancer lesions (T2-T4) were studied by FLT-PET. For comparison, [18F]fluorodeoxyglucose (FDG) PET scans were performed in six patients. Thirteen of the 14 primary tumours demonstrated focally increased FLT uptake (SUVmean=3.4±1.1). Seven out of eight patients with histologically proven axillary lymph node metastases showed focally increased FLT uptake in the corresponding areas (SUVmean=2.4±1.2). The lowest SUV (mean =0.7) was observed in one of two inflammatory cancers. The contrast between primary tumours or metastases and surrounding tissue was high in most cases. In direct comparison to FDG-PET, the SUVs of primary tumours (5/6) and axillary lymph node metastases (3/4) were lower in FLT-PET (SUVFLT: 3.2 vs SUVFDG: 4.7 in primary tumours and SUVFLT: 2.9 vs SUVFDG: 4.6 in lymph node metastases). Since FLT uptake in surrounding breast tissue was also lower, tumour contrast was comparable to that with FDG. It is of note that normal FLT uptake was very low in the mediastinum, resulting in a higher tumour-to-mediastinum ratio as compared to FDG (P=0.03). FLT-PET is suitable for the diagnosis of primary breast cancer and locoregional metastases. High image contrast may facilitate the detection of small foci, especially in the mediastinum. (orig.)

    2010-01-01

    The US health care system has become increasingly unsustainable, threatened by poor quality and spiraling costs. Many Americans are not receiving recommended preventive care, including cancer screening tests. Passage of the Affordable Care Act in March 2010 has the potential to reverse this course by increasing access to primary care providers, extending coverage and affordability of health insurance, and instituting proven quality measures. In order for health care reform to succeed, it will require a stronger primary care workforce, a new emphasis on patient-centered care, and payment incentives that reward quality over quantity. Innovations such as patient-centered medical homes, accountable care organizations, and improved quality reporting methods are central features of a redesigned health care delivery system and will ultimately change the face of cancer care in the United States.

  13. The posttreatment mean apparent diffusion coefficient of primary tumor is superior to pretreatment ADCmean of primary tumor as a predictor of prognosis with cervical cancer

    International Nuclear Information System (INIS)

    The objective of this study was to investigate the correlation of pretreatment and posttreatment measurements as the mean apparent diffusion coefficient (ADCmean) by diffusion-weighted magnetic resonance imaging (DWI) findings with prognostic factors in patients with squamous cell carcinoma (SCC) of primary cervical cancer. The pretreatment and posttreatment ADCmean of the primary tumor were examined for their correlations with the prognosis in 69 patients with SCC of primary cervical cancer by radiotherapy (RT) with or without concurrent chemotherapy (CCRT). The median disease-free survival (DFS) and overall survival (OS) times of patients were 20.97 and 23.47 months (follow-up periods for DFS and OS: 1–72 and 1–72 months). The DFS and OS rates of patients with low pretreatment and posttreatment ADCmean of the primary tumor were also significantly worse than those of patients exhibiting high pretreatment and posttreatment ADCmean of the primary tumor (DFS; P = 0.0130 and P < 0.0001, OS; P = 0.0010 and P < 0.0001). Multivariate analyses showed that low posttreatment ADCmean of the primary tumor was an independent prognostic factor for DFS and OS (P < 0.0001 and P < 0.0001). The low posttreatment ADCmean of the primary tumor is a useful clinical prognostic biomarker for recurrence and survival in patients with cervical cancer. The low posttreatment ADCmean of the primary tumor is a useful clinical prognostic biomarker for recurrence and survival in patients with cervical cancer

    The first case of primary lung cancer in a transplanted lung was described in 2001. Since then, only 5 cases of lung cancer in donated lung have been reported. We present one more patient with non-small cell cancer in the transplanted lung treated with stereotactic body radiation therapy. In most cases of primary lung cancer in transplanted lung, rapid progression of the cancer was reported. Occurrence of the locoregional failure in our case could be explained by factors related to the treatment protocol and also to underlying immunosuppression.

    Tuberculosis peritonitis is a rare manifestation of extrapulmonary tuberculosis. The results of gallium-67 scintigraphy of three patients with tuberculosis peritonitis were reviewed to assess its usefulness in the diagnosis of this condition. Tuberculosis peritonitis was associated with diffuse or focal abdominal localization and decreased hepatic accumulation of gallium-67. These gallium-67 scan features of tuberculosis peritonitis may help to optimize the diagnosis and management of this disease. PMID:10435380

  19. CT findings of peritoneal tuberculosis and peritoneal carcinomatosis: relationship between peritoneal change and omental infiltration

    International Nuclear Information System (INIS)

    To compare the CT findings of peritoneal tuberculosis (PT) and peritoneal carcinomatosis (PC) based on the morphologic features of the peritoneum and assess the relationship between the degree of peritoneal thickness and the severity of omental infiltration in PT and PC. We retrospectively reviewed the CT findings of 15 patients with PT and 14 with PC. We checked morphologic changes of the peritoneum as seen on CT, for the following points: 1) the presence of peritoneal change: 2) the pattern of any change-diffuse thickening, plaque or nodularity, combined thickening (diffuse and plaque, or nodularity) 3) the degree of thickness on the whole peritoneum - mild (grossly definite, but not more than 3mm), moderate (more than 3mm); 4) the presence of irregularity on the peritoneal surface. We also evaluated the significance of the relationship between peritoneal thickness and omental infiltration in both disease entities. The degree of omental infiltration was described as follows : grade 1 (no change or focal smudge pattern); grade 2 (diffuse smudge), grade 3 (omental cake regardless extent). Peritoneal change was seen in 12 of 15 PT patients and in 7 of 14 PC patients. In all 12 PT patients, the pattern of change was diffuse thickening, and among the seven PC patients, there was diffuse thickening in one, plaque or nodular thickening in four, and combined thickening in two. In PT patients, the degree of thickness on the whole peritoneum was mild in six and moderate in six, and in PC patients it was mild in two and moderate in one. An irregular peritoneum surface was seen in one patient with PT and in two with PC. The degree of omental infiltration in PT was grade 1 in four patients, grade 2 in six and grade 3 in five. In PC, it was grade 1 in six patients, grade 2 in two and grade 3 in six. Smooth diffuse thickening of the peritoneum was seen in 11 of 15 PT cases and in one of 14 PC (P 0.5). In PT and PC different CT findings based on peritoneal morphologic changes

    Purpose: To evaluate the primary Gleason grade (GG) in Gleason score (GS) 7 prostate cancers for risk of non-organ-confined disease with the goal of optimizing radiotherapy treatment option counseling. Methods: One thousand three hundred thirty-three patients with pathologic GS7 were identified in the Duke Prostate Center research database. Clinical factors including age, race, clinical stage, prostate-specific antigen at diagnosis, and pathologic stage were obtained. Data were stratified by prostate-specific antigen and clinical stage at diagnosis into adapted D’Amico risk groups. Univariate and multivariate analyses were performed evaluating for association of primary GG with pathologic outcome. Results: Nine hundred seventy-nine patients had primary GG3 and 354 had GG4. On univariate analyses, GG4 was associated with an increased risk of non-organ-confined disease. On multivariate analysis, GG4 was independently associated with seminal vesicle invasion (SVI) but not extracapsular extension. Patients with otherwise low-risk disease and primary GG3 had a very low risk of SVI (4%). Conclusions: Primary GG4 in GS7 cancers is associated with increased risk of SVI compared with primary GG3. Otherwise low-risk patients with GS 3+4 have a very low risk of SVI and may be candidates for prostate-only radiotherapy modalities.

    Background: malignant peritoneal mesothelioma (MPM) is a rare peritoneal mesothelial neoplasm. Ki67 and BCL2 are established prognostic markers in several cancers. High Ki67 expression indicates tumour progression, whilst similar expression of BCL2 retards tumour replication. Traditionally, prognosis in MPM is gauged with a single biomarker assessed separately in a dichotomous manner. Here, we examine prognosis with dual biomarkers incorporated in a model to predict survival. Materials and me...

    Histopathologic features could affect the FDG uptake of primary gastric cancer and detection rate on FDG PET/CT. The aim of this study was to evaluate the FDG uptake of primary gastric cancer by correlating it with the histopathologic features of the tumors. Fifty patients with locally advanced gastric adenocarcinoma who were referred for preoperative FDG-PET/CT scans were enrolled in this study. The detection rate of PET/CT and maximum standardized uptake values (SUV{sub max}) of the primary tumor were compared using the WHO, Lauren, Ming and Borrmann classifications and tumor size and location. In 45 of the 50 patients (90 %), the primary gastric tumors were detected by FDG PET/CT. On comparison using the WHO classification, the detection rate and SUV{sub max} of the tubular type were significantly higher than those of the poorly cohesive type. On comparison using the Lauren and Ming classifications, the SUV{sub maxs} of the intestinal type and expanding type were significantly higher than those of the diffuse and infiltrative type, respectively. On comparison using the Borrmann classification and tumor size and location, there was no significant difference in the detection rate and SUV{sub max} of primary gastric tumors. This study demonstrates that the poorly cohesive type according to the WHO classification, diffuse type according to the Lauren classification and infiltrative type according to the Ming classification have low FDG uptake in patients with locally advanced gastric carcinoma. Understanding the relationship between primary tumor FDG uptake and histopathologic features would be helpful in detecting the primary tumor by FDG PET/CT in patients with gastric cancer.

    Corn starch particles are used as a surgical glove lubricant. At present there is no better alternative for this lubricant. Implantation of corn starch particles into the peritoneal cavity can induce foreign body reactions, starch peritonitis and starch granulomata, and may cause adhesions and intestinal obstruction. Starch peritonitis should be treated conservatively.

  7. Second primary cancers after adjuvant radiotherapy in early breast cancer patients: A national population based study under the Danish Breast Cancer Cooperative Group (DBCG)

    International Nuclear Information System (INIS)

    Background and purpose: To analyze the long-term risk of second primary solid non-breast cancer in a national population-based cohort of 46,176 patients treated for early breast cancer between 1982 and 2007. Patients and methods: All patients studied were treated according to the national guidelines of the Danish Breast Cancer Cooperative Group. The risk of second primary cancers was estimated by Standardised incidence ratios (SIRs) and multivariate Cox regression models were used to estimate adjusted hazard ratios (HR) among irradiated women compared to non-irradiated. All irradiated patients were treated on linear accelerators. Second cancers were a priori categorized into two groups; radiotherapy-associated- (oesophagus, lung, heart/mediastinum, pleura, bones, and connective tissue) and non-radiotherapy-associated sites (all other cancers). Results: 2358 second cancers had occurred during the follow-up. For the radiotherapy-associated sites the HR among irradiated women was 1.34 (95% CI 1.11–1.61) with significantly increased HRs for the time periods of 10–14 years (HR 1.55; 95% CI 1.08–2.24) and ⩾15 years after treatment (HR 1.79; 95% CI 1.14–2.81). There was no increased risk for the non-radiotherapy-associated sites (HR 1.04; 95% CI 0.94–1.1). The estimated attributable risk related to radiotherapy for the radiotherapy-associated sites translates into one radiation-induced second cancer in every 200 women treated with radiotherapy. Conclusions: Radiotherapy treated breast cancer patients have a small but significantly excess risk of second cancers

    Full Text Available Intraperitoneal infection known as peritonitis is a major killer in the practice of clinical surgery. Tertiary peritonitis (TP may be defined as intra-abdominal infection that persists or recurs ³48 h following successful and adequate surgical source control. A planned or on-demand relaparotomy after an initial operation is probably most frequent way to diagnose TP, but is a late event to occur. Hence it is desirable to have timely and nonoperative diagnosis of TP after the initial operation and subsequent initiation of an appropriate therapy to reduce the complications and to improve the outcome.

However, little is known about the contribution of normal cells to the prostatic microenvironment and inflammation. We aim to study the contribution of normal prostate epithelial cells to prostate inflammation and to link the inflammatory status of normal cells to prostate cancer aggressiveness.Materials and methods: Short-term primary cell cultures of normal epithelial prostate cells were derived from prostate biopsies from 25 men undergoing radical prostatectomy, cystoprostatectomy, or organ donation. Cells were treated with polyinosinic:polycytidylic acid, a mimic of double-stranded viral RNA and a potent inducer of the inflammatory response. Secretion of interleukin (IL-8 in the cell culture medium by untreated and treated cells was measured and we determined the association between IL-8 levels in these primary cell cultures and prostate cancer characteristics. The Fligner–Policello test was used to compare the groups.Results: Baseline and induced IL-8 secretion were highly variable between cultured cells from different patients. This variation was not related to drug use, past medical history, age, or preoperative prostate-specific antigen value. Nonetheless, an elevated secretion of IL-8 from normal cultured epithelial cells was associated with prostate cancer aggressiveness (P=0.0005.Conclusion: The baseline secretion of IL-8 from normal prostate epithelial cells in culture is strongly correlated with cancer aggressiveness and may drive prostate cancer

    OBJECTIVE: The purpose of this article is to present the spectrum of radiologic findings of encapsulating peritoneal sclerosis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). CONCLUSION: Although a rare diagnosis, encapsulating peritoneal sclerosis in patients undergoing CAPD has a high morbidity and mortality. Diagnosis is often delayed because clinical features are insidious and nonspecific. Radiologic imaging may be helpful in the early diagnosis of encapsulating peritoneal sclerosis and in facilitating timely intervention for CAPD patients with encapsulating peritoneal sclerosis.

  14. Targeted biomarker profiling of matched primary and metastatic estrogen receptor positive breast cancers.

    Directory of Open Access Journals (Sweden)

    Erica B Schleifman

    Full Text Available Patients with newly diagnosed, early stage estrogen receptor positive (ER+ breast cancer often show disease free survival in excess of five years following surgery and systemic adjuvant therapy. An important question is whether diagnostic tumor tissue from the primary lesion offers an accurate molecular portrait of the cancer post recurrence and thus may be used for predictive diagnostic purposes for patients with relapsed, metastatic disease. As the class I phosphatidylinositol 3' kinase (PI3K pathway is frequently activated in ER+ breast cancer and has been linked to acquired resistance to hormonal therapy, we hypothesized pathway status could evolve over time and treatment. Biomarker analyses were conducted on matched, asynchronous primary and metastatic tumors from 77 patients with ER+ breast cancer. We examined whether PIK3CA and AKT1 alterations or PTEN and Ki67 levels showed differences between primary and metastatic samples. We also sought to look more broadly at gene expression markers reflective of proliferation, molecular subtype, and key receptors and signaling pathways using an mRNA analysis platform developed on the Fluidigm BioMark™ microfluidics system to measure the relative expression of 90 breast cancer related genes in formalin-fixed paraffin-embedded (FFPE tissue. Application of this panel of biomarker assays to matched tumor pairs showed a high concordance between primary and metastatic tissue, with generally few changes in mutation status, proliferative markers, or gene expression between matched samples. The collection of assays described here has been optimized for FFPE tissue and may have utility in exploratory analyses to identify patient subsets responsive to targeted therapies.

    Infections with oncogenic human papillomavirus (HPV) strains are recognized as the major risk factor for developing malignant lesions in the uterine cervix. However, several findings have demonstrated cooperation between HPV infection and 17β-estradiol (E2) in cervical carcinogenesis. The 17β-hydroxysteroid dehydrogenase type 1 (HSD17B1) is the enzyme involved in the transformation of estrone (E1) into E2. In this study, we identified the HSD17B1 transcript and protein in HeLa, SiHa, Ca Ski and C-33A cervical cancer cells. These cells were able to convert E1 to E2 in a time-dependent manner. Moreover, we identified the HSD17B1 transcript and protein in primary cancerous tissues (n=28) and in histologically unchanged tissues (n=25). We did not observe significant differences (P=0.33) between the HSD17B1 transcript levels in cancerous tissues and histologically unchanged tissues. However, we found an overrepresentation of the HSD17B1 protein in cancerous tissues compared with histologically unchanged tissues (Pprotein in primary cervical cancerous tissues may be responsible for the local conversion of E1 to E2.

    Full Text Available A 64-year-old man was diagnosed with unresectable cancer of the trachea. He was treated definitively with a novel chemoradiation regimen. Cisplatin-based chemotherapy (ChT was given for two cycles as induction, followed by concurrent administration of this ChT with external beam radiotherapy (RT (total dose 60 Gy. An unexpected partial tumour response was noted after the induction of ChT alone. Six weeks after finishing ChT/RT, complete response of the lesion was noted on computed tomography imaging. Two years later, the patient was free of disease. Primary chemoradiation appears to be effective in managing locally advanced tracheal cancer.

    Peritoneal metastasis (PM) has traditionally been approached with therapeutic nihilism. The evolution of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) over the last two decades, however, has caused a paradigm shift in treatment for PM. This modality is rapidly gaining acceptance as standard of care for PM from various cancers. This article reviews the current literature regarding the use of CRS/HIPEC for PM from the most common intra-abdominal malignancies. PMID:25164477

  3. Amphiregulin and Epiregulin mRNA expression in primary colorectal cancer and corresponding liver metastases

    International Nuclear Information System (INIS)

    Amphiregulin (AREG) and Epiregulin (EREG), ligands of EGFR, are reported to be predictive biomarkers of colorectal cancer patients treated with Cetuximab, an anti-EGFR antibody. The purpose of this study is to determine the correlation of AREG and EREG expression between primary colorectal cancer and corresponding liver metastases. One hundred twenty colorectal cancer patients with liver metastases (100 with synchronous metastases, 20 with metachronous) were evaluated. No patients had ever received anti-EGFR antibody agents. AREG and EREG mRNA expression from both the primary tumor and liver metastases were measured using real-time RT-PCR. KRAS codon 12, 13 mutation status was analyzed by direct sequencing. Modest, but significant, correlations were observed between primary tumor and corresponding liver metastases in both AREG mRNA expression (Rs = 0.54, p < 0.0001) and EREG mRNA expression (Rs = 0.58, p < 0.0001). AREG and EREG mRNA expression was strongly correlated in both the primary tumor (Rs = 0.81, p < 0.0001) and the liver metastases (Rs = 0.87, p < 0.0001). No significant survival difference was observed between low and high AREG or EREG patients when all 120 patients were analyzed. However, when divided by KRAS status, KRAS wild-type patients with low EREG mRNA levels in the primary site showed significantly better overall survival rates than those with high levels (p = 0.018). In multivariate analysis, low EREG expression was significantly associated with better overall survival (p = 0.006). AREG and EREG expression showed a modest correlation between primary tumor and liver metastases. As EREG mRNA expression was associated with decreased survival, it is appeared to be a useful prognostic marker in KRAS wild-type patients who never received anti-EGFR therapy

    2015-01-01

    Malignant peritoneal mesothelioma (MPM) is a rare and fatal cancer arising from the mesothelial cells lining the peritoneum. This typically occurs in men in their fifth and sixth decades, but can be seen in women and any age group. Pleural and extrapleural mesothelioma can arise in the setting of asbestos exposure, but other reported causes of MPM include exposure to silicate fibers and radiation therapy. Because it presents with vague symptoms such as abdominal pain, anorexia, and weight loss, it is generally advanced at diagnosis. This is a case of MPM that presented initially at contrast-enhanced computed tomography as a small focal lesion in the lesser sac, ultimately resulting in death from complications of the disease.

    Metastasis is a process consisting of cells spreading from the primary site of the cancer to distant parts of the body. Our understanding of this spread is limited and molecular mechanisms causing particular characteristics of metastasis are still unknown. There is some evidence that primary renal cell carcinoma (RCC) and metastases of RCC exhibit molecular differences that may effect on the biological characteristics of the tumor. Some authors have detected differences in clear cell and nonclear cell component between these 2 groups of tumors. Investigators have also determined that primary RCC and metastases of RCC diverge in their range of renal-specific markers and other protein expression, gene expression pattern, and microRNA expression. There are also certain proteins that are variously expressed in primary RCCs and their metastases and have effect on clinical outcome, e.g., endothelin receptor type B, phos-S6, and CD44. However, further studies are needed on large cohorts of patients to identify differences representing promising targets for prognostic purposes predicting disease-free survival and the metastatic burden of a patient as well as their suitability as potential therapeutic targets. To sum up, in this review we have attempted to summarize studies connected with differences between primary RCC and its metastases and their influence on the biological characteristics of renal cancer.

The aim was to investigate the gene expression of MSH2 in primary operable colorectal cancer in correlation with MSI, protein expression, and promoter hypermethylation. In a cohort of 210 patients, the primary tumor and...... promoter was only detected in 14 samples and only at a low level with no correlation to gene expression. MSH2 gene expression was not a prognostic factor for overall survival in univariate or multivariate analysis. The gene expression of MSH2 is a potential quantitative marker ready for further clinical...

  7. Calcifying liver metastases. Computed tomography imaging and incidence of primary colorectal cancer

    International Nuclear Information System (INIS)

    A total of 24 patients with liver metastases of the calcifying type were detected during CT scan imaging for cancer of different primary origin (colorectal, ovarian, mammary, gastric, prostatic melanoma). These calcifying metastases represented 27% of the 89 liver metastases cases detected, and the incidence of a colorectal origin for these calcifying lesions (20% of cases) appears to be highly significant, their number being relatively larger than reported in previous studies. Identification of liver calcifications of possible diagnostic importance requires a two-stage CT scan investigation, before and after bolus. Paraclinical examinations should be directed selectively towards the digestive tract when the primary tumor is unknown

  9. Cancer testis antigens and NY-BR-1 expression in primary breast cancer: prognostic and therapeutic implications

    International Nuclear Information System (INIS)

    Cancer–testis antigens (CTA) comprise a family of proteins, which are physiologically expressed in adult human tissues solely in testicular germ cells and occasionally placenta. However, CTA expression has been reported in various malignancies. CTAs have been identified by their ability to elicit autologous cellular and or serological immune responses, and are considered potential targets for cancer immunotherapy. The breast differentiation antigen NY-BR-1, expressed specifically in normal and malignant breast tissue, has also immunogenic properties. Here we evaluated the expression patterns of CTAs and NY-BR-1 in breast cancer in correlation to clinico-pathological parameters in order to determine their possible impact as prognostic factors. The reactivity pattern of various mAbs (6C1, MA454, M3H67, 57B, E978, GAGE #26 and NY-BR-1 #5) were assessed by immunohistochemistry in a tissue micro array series of 210 randomly selected primary invasive breast cancers in order to study the diversity of different CTAs (e.g. MAGE-A, NY-ESO-1, GAGE) and NY-BR-1. These expression data were correlated to clinico-pathological parameters and outcome data including disease-free and overall survival. Expression of at least one CTA was detectable in the cytoplasm of tumor cells in 37.2% of the cases. NY-BR-1 expression was found in 46.6% of tumors, respectively. Overall, CTA expression seemed to be linked to adverse prognosis and M3H67 immunoreactivity specifically was significantly correlated to shorter overall and disease-free survival (p=0.000 and 0.024, respectively). Our findings suggest that M3H67 immunoreactivity could serve as potential prognostic marker in primary breast cancer patients. The exclusive expression of CTAs in tumor tissues as well as the frequent expression of NY-BR-1 could define new targets for specific breast cancer therapies

  10. Measurement of asbestos bodies in lung tissue of autopsy cases diagnosed with primary lung cancer

    International Nuclear Information System (INIS)

    To investigate the relation between asbestos-related lung cancer and the concentration of asbestos bodies in lung tissue, we analyzed the concentration in 24 autopsy cases diagnosed with primary lung cancer, with regard to the gender, age, histological type of lung cancer and occupation of each case. The asbestos bodies were measured according to Kohyama's method. Positive cases (more than 5,000 bodies per 1 g of dry lung tissue) were further analyzed for asbestosis and pleural plaques by chest X-ray and chest CT. Two cases exhibited more than 5,000 bodies, five cases between 1,000 and 5,000, and seventeen cases less than 1,000. The occupation of the two positive cases was not informative: one demonstrated neither asbestosis nor pleural plaques, and the other showed only pleural plaques. Although the number of cases of asbestos-related lung cancer is minimal among all lung cancer cases, the number of the former may exceed that of mesothelioma patients. Not only physicians but also radiologists, surgeons and pathologists need to collaborate in the diagnosis of asbestos-related lung cancer. (author)

  11. Studies on pulmonary ventilation-perfusion scintigraphy with Xe-133 in primary lung cancer, 1

    International Nuclear Information System (INIS)

    Regional lung ventilation-perfusion scintigraphy by xenon gas was performed on 14 normal cases (normal group) and 86 cases of primary lung cancer (lung cancer group). The patients were measured in a sitting position using a scintillation camera. In normal group, the value of V, Q was higher in the lower lung field than in the upper lung field, the value of MTT was rather delayed in the upper lung field than in the lower lung field, proving to that lung clearance was better in the lower lung field than in the upper lung field. In lung cancer group, VQ match (pattern I, II) was 61 cases (71%) and VQ mismatch (pattern III, IV) was 25 cases (29%). The pattern II (VQ matched defect) accounted for 63% in lung cancer group. In this pattern, the region of disorder of V and Q was corresponded respectively, but disorder grade was not always accorded. The pattern III (normal V and disordered Q) was mainly seen in AH group (hilar type) and D group (lymph node swelling type). The V/Q in lung cancer group was widely distributed to the range of 0 to 5.8. The value of MTT was rather delayed in all cases of lung cancer group than in the normal group, because delayed MTT in focal lesion was markedly affected to whole lung. (author)

  14. Hypothesis: primary antiangiogenic method proposed to treat early stage breast cancer

    International Nuclear Information System (INIS)

    Women with Down syndrome very rarely develop breast cancer even though they now live to an age when it normally occurs. This may be related to the fact that Down syndrome persons have an additional copy of chromosome 21 where the gene that codes for the antiangiogenic protein Endostatin is located. Can this information lead to a primary antiangiogenic therapy for early stage breast cancer that indefinitely prolongs remission? A key question that arises is when is the initial angiogenic switch thrown in micrometastases? We have conjectured that avascular micrometastases are dormant and relatively stable if undisturbed but that for some patients angiogenesis is precipitated by surgery. We also proposed that angiogenesis of micrometastases very rarely occurs before surgical removal of the primary tumor. If that is so, it seems possible that we could suggest a primary antiangiogenic therapy but the problem then arises that starting a therapy before surgery would interfere with wound healing. The therapy must be initiated at least one day prior to surgical removal of the primary tumor and kept at a Down syndrome level perhaps indefinitely. That means the drug must have virtually no toxicity and not interfere meaningfully with wound healing. This specifically excludes drugs that significantly inhibit the VEGF pathway since that is important for wound healing and because these agents have some toxicity. Endostatin is apparently non-toxic and does not significantly interfere with wound healing since Down syndrome patients have no abnormal wound healing problems. We propose a therapy for early stage breast cancer consisting of Endostatin at or above Down syndrome levels starting at least one day before surgery and continuing at that level. This should prevent micrometastatic angiogenesis resulting from surgery or at any time later. Adjuvant chemotherapy or hormone therapy should not be necessary. This can be continued indefinitely since there is no acquired resistance that

  15. Expression patterns of CEACAM5 and CEACAM6 in primary and metastatic cancers

    International Nuclear Information System (INIS)

    Many breast, pancreatic, colonic and non-small-cell lung carcinoma lines express CEACAM6 (NCA-90) and CEACAM5 (carcinoembryonic antigen, CEA), and antibodies to both can affect tumor cell growth in vitro and in vivo. Here, we compare both antigens as a function of histological phenotype in breast, pancreatic, lung, ovarian, and prostatic cancers, including patient-matched normal, primary tumor, and metastatic breast and colonic cancer specimens. Antigen expression was determined by immunohistochemistry (IHC) using tissue microarrays with MN-15 and MN-3 antibodies targeting the A1B1- and N-domains of CEACAM6, respectively, and the MN-14 antibody targeting the A3B3 domain of CEACAM5. IHC was performed using avidin-biotin-diaminobenzide staining. The average score ± SD (0 = negative/8 = highest) for each histotype was recorded. For all tumors, the amount of CEACAM6 expressed was greater than that of CEACAM5, and reflected tumor histotype. In breast tumors, CEACAM6 was highest in papillary > infiltrating ductal > lobular > phyllodes; in pancreatic tumors, moderately-differentiated > well-differentiated > poorly-differentiated tumors; mucinous ovarian adenocarcinomas had almost 3-fold more CEACAM6 than serous ovarian adenocarcinomas; lung adenocarcinomas > squamous tumors; and liver metastases of colonic carcinoma > primary tumors = lymph nodes metastases > normal intestine. However, CEACAM6 expression was similar in prostate cancer and normal tissues. The amount of CEACAM6 in metastatic colon tumors found in liver was higher than in many primary colon tumors. In contrast, CEACAM6 immunostaining of lymph node metastases from breast, colon, or lung tumors was similar to the primary tumor. CEACAM6 expression is elevated in many solid tumors, but variable as a function of histotype. Based on previous work demonstrating a role for CEACAM6 in tumor cell migration, invasion and adhesion, and formation of distant metastases (Blumenthal et al., Cancer Res 65: 8809–8817, 2005

    AIM: To ascertain the adequacy of the microsatellite instability (MSI) as a prognostic indicator by assessing MSI status of patients with double primary gastric and colorectal cancer (DPGCC).METHODS: Sixteen patients were studied, all of whom exhibited sporadic DPGCC, and had no family history of hereditary non-polyposis colorectal cancer, according to the Amsterdam criteria. A total of 32 cancers from 16DPGCC patients, and 216 single primary CRC, were assessed for MSI in 5 microsatellite loci, BAT25, BAT26,D2S123, D5S346, and D17S250.RESULTS: MSI was observed in 6 (37.5%) of 16 GC and 4 (25.0%) of 16 CRC. Thirty tumors (13.9%) out of 216single primary CRC and one tumor (16.7%) out of 6 double primary CRC were found to be microsatellite unstable. Of the 6 GC with MSI in DPGCC, 5 (31.3%) were MSI-high and one (6.3%) was MSI-low. In 5 of 16 DPGCC patients,the cancer recurred in or adjacent to the anastomosis or metastasized to the kidney or lung. The MSI-high DPGCC cases were associated with a younger age of onset (47.5 years vs 62.5 years), higher frequency of lymph node metastasis (100% vs 25%), and advanced Dukes stage (C, 100% vs 41.7%), as well as a higher frequency of recurrence or metastasis (100% vs 8.3%). Only recurrence or metastasis showed statistical significance by Fisher's exact test.CONCLUSION: Our data suggest that MSI may play an important role in the development of DPGCC, and that it may be used clinically as a molecular predictive marker for recurrence or late metastasis of DPGCC.

    Surgery is often the first therapeutic indication in cancer. Patient survival essentially depends on the completeness of tumor resection. This is a major challenge, particularly in patients with peritoneal carcinomatosis (PC), where tumors are widely disseminated in the large peritoneal cavity. These small tumors can be difficult to visualize and are often positioned in delicate locations, further increasing the risk of producing serious tissue/organ damage during their ablation. We propose an innovative therapeutic approach based on intraoperative fluorescence (IF) guided electrochemotherapy (ECT) for the treatment of peritoneal micro-metastases. ECT combines the effects of tissue electro-permeabilization (EP) with the administration of an antimitotic agent (bleomycin) that has poor permeability across intact membranes. IF significantly improves the detection of small tumor lesions. ECT is clinically validated for the treatment of cutaneous tumors in animals and humans, but this is the first time that it has been used along with IF imaging for the targeted treatment of peritoneal metastases in a preclinical model. We set up a murine model of PC that develops secondarily to the resection of a distant primary tumor. Tumor growth and metastasis were finely monitored by non-invasive multimodal imaging (bioluminescence and 3D fluorescence/microCT). Once metastases were detected, mice were randomized into three groups: the ECT group (bleomycin injected intravenously followed by EP) and 2 control groups (bleomycin alone and EP alone). Twenty four hours after the intravenous injection of the tumor targeting agent Angiostamp™700, mice in all groups underwent an abdominal surgery for metastases exploration assisted by fluorescence imaging with the Fluobeam®700 portative device. EP was applied to every nodule detected by IF, except in the bleomycin control group. After surgery, the metastatic invasion was tracked by bioluminescence imaging. In mice treated with bleomycin

  10. Treatment strategy for primary lung cancer in patients over 80 years old

    International Nuclear Information System (INIS)

    In order to establish the treatment strategies for primary lung cancer patients over 80 years old, we retrospectively analyzed the treatment methods and outcome of 174 patients admitted to our hospital from April 1987 to March 2002. A total of 174 patients were classified into stage I (n=25), stage II (n=7), stage III (n=64) and stage IV (n=78). Although the general condition and nutritional condition of patients over 80 years were comparatively poorer than all patients with primary lung cancer, there was no significant difference. In total, 73 patients were treated with surgical resection (13 patients), radiation (35 patients), chemotherapy (15 patients), and chemo-radiation (10 patients). Although the surgical treatment group predominantly included patients at stage I, there were no significant differences in general or nutritional condition, pulmonary function or arterial blood gas among the four treatment groups. The outcome of surgically treated patients was significantly better (p<0.05), whereas there were no significant differences among the other three groups or between the treated group and untreated groups. Only surgical treatment was evaluated to improve the prognosis of primary lung cancer patients over 80 years when respiratory function was adequate for surgical treatment. (author)

  11. Primary Surgery or Neoadjuvant Chemotherapy in Advanced Ovarian Cancer: The Debate Continues….

    2016-01-01

    Primary debulking surgery (PDS) followed by platinum-based chemotherapy has been the cornerstone of treatment for advanced ovarian cancer for decades. Primary debulking surgery has been repeatedly identified as one of the key factors in improving survival in patients with advanced ovarian cancer, especially when minimal or no residual disease is left behind. Achieving these results sometimes requires extensive abdominal and pelvic surgical procedures and consultation with other surgical teams. Some clinicians who propose a primary chemotherapy approach reported an increased likelihood of leaving no macroscopic disease after surgery and improved patient-reported outcomes and quality-of-life (QOL) measures. Given the ongoing debate regarding the relative benefit of PDS versus neoadjuvant chemotherapy (NACT), tumor biology may aid in patient selection for each approach. Neoadjuvant chemotherapy offers the opportunity for in vivo chemosensitivity testing. Studies are needed to determine the best way to evaluate the impact of NACT in each individual patient with advanced ovarian cancer. Indeed, the biggest utility of NACT may be in research, where this approach provides the opportunity for the investigation of predictive markers, mechanisms of resistance, and a forum to test novel therapies.

    Full Text Available Objective: The present study evaluated the treatment effectiveness of sodium cantharidinate/vitamin B6 in patient with middle/late stage primary liver cancer. Materials and Methods: A 3-month follow-up study on 104 patients with primary liver cancer was carried out. Regular medication treatment was applied to 41 patients and sodium cantharidinate/vitamin B6 combined with the regular medication was applied to 63 patients. The treatment effectiveness and prognosis were evaluated using the statistical methods. Results: At the end of the treatment, no significant difference was detected between the two groups; 1-month follow-up survey showed that in the treatment group, the death rate was lower, the treatment gain was maintained longer and the tumor morphology was maintained better, compared with the control group; 3-month follow-up study showed that there was not significance difference between the two groups. Conclusion: Sodium cantharidinate/vitamin B6 might be used as auxiliary drug in patients with primary liver cancer and could improve the treatment outcomes for a short-term period.

To determine the relative roles of perfusion, inhalation and ventilation scintigraphy, the relationship between the count ratio of the affected side to the healthy side and the post-surgical histological lymph nodes factors were observed in this study. These scintigraphic count ratio's in patients with primary lung cancer did not reflect the pN factors except in the perfusion study in patients with hilar primary lung cancer. (author)

  14. In situ identification of CD44+/CD24- cancer cells in primary human breast carcinomas.

    Giuseppe Perrone

    Full Text Available Breast cancer cells with the CD44+/CD24- phenotype have been reported to be tumourigenic due to their enhanced capacity for cancer development and their self-renewal potential. The identification of human tumourigenic breast cancer cells in surgical samples has recently received increased attention due to the implications for prognosis and treatment, although limitations exist in the interpretation of these studies. To better identify the CD44+/CD24- cells in routine surgical specimens, 56 primary breast carcinoma cases were analysed by immunofluorescence and confocal microscopy, and the results were compared using flow cytometry analysis to correlate the amount and distribution of the CD44+/CD24- population with clinicopathological features. Using these methods, we showed that the breast carcinoma cells displayed four distinct sub-populations based on the expression pattern of CD44 and CD24. The CD44+/CD24- cells were found in 91% of breast tumours and constituted an average of 6.12% (range, 0.11%-21.23% of the tumour. A strong correlation was found between the percentage of CD44+/CD24- cells in primary tumours and distant metastasis development (p = 0.0001; in addition, there was an inverse significant association with ER and PGR status (p = 0.002 and p = 0.001, respectively. No relationship was evident with tumour size (T and regional lymph node (N status, differentiation grade, proliferative index or HER2 status. In a multivariate analysis, the percentage of CD44+/CD24- cancer cells was an independent factor related to metastasis development (p = 0.004. Our results indicate that confocal analysis of fluorescence-labelled breast cancer samples obtained at surgery is a reliable method to identify the CD44+/CD24- tumourigenic cell population, allowing for the stratification of breast cancer patients into two groups with substantially different relapse rates on the basis of CD44+/CD24- cell percentage.

    The incidence of Second Primary Tumors in the upper aerodigestive tract varies from 5 to 30 %. Most of them are located either in the same anatomical region or in the lungs, and are related to a poor overall survival. Our objective is to assess the incidence of Second Primary Tumors, factors related to its outcome, frequent associations, and impact on overall survival. 27 patients with Second Primary Tumors were reviewed out of 307 with head and neck cancer, between 2002 and 2011. Patients had a minimum follow-up period of 3 years, or until their death after the last treatment. Sex: 85.2 % were male; male:female ratio of 23:4. The mean age of appearance for the primary tumor was 66.8 years. Only 1 patient had a synchronous Second Primary Tumor, while 26 had metachronous Second Primary Tumors. Second neoplasms were grouped into synchronous and metachronous for statistical analysis. The following parameters were considered: age at diagnosis of the first tumor, gender, smoking and persistence of the habit, primary tumor's location in the larynx, association between two squamous cell carcinomas (index and second primary tumor), and radiotherapy for the primary tumor. The incidence of Second Primary Tumors was 8.79 %. Overall survival of metachronous tumors was 95 months (7.9 years). The primary tumor's location that prevailed when developing a Second Primary Tumor was the larynx. Regarding the histology, the most common association was head and neck squamous cell carcinoma with head and neck squamous cell carcinoma (9 patients). The Second Primary Tumor was the cause of death in 51.9 % of the patients and its most frequent location was the lungs. 19 patients underwent radiotherapy. Second Primary Tumors are common in the head and neck. The authors would like to enforce the importance of an extended follow-up, since second neoplasms worsen considerably the patient's prognosis. Patients who keep on smoking after treatment decrease even more their overall survival

  17. Rifaximin for the prevention of spontaneous bacterial peritonitis

    According to a review article by Biecker et al published in a previous issue of World Journal of Gastroenterology in March 2011, intestinal decontamination with norfloxacin remains the mainstay of primary prophylaxis of spontaneous bacterial peritonitis (SBP) at the expense of development of quinolone-resistant bacteria after long-term use. In our research, the administration of a 4-wk regimen with rifaximin 1200 mg/d reduced significantly the ascitic neutrophil count in cirrhotic patients wi...

Further, we describe the future potential of the cohort as an international resource for epidemiological and health services research studies. Methods: The CaP cohort comprises information from three Danish subcohorts set up in 2004–2005, 2007–2008, and 2010 on newly diagnosed cancer patients aged 18 years or older. General practitioner (GP-reported and patient-reported data from six questionnaires generated information on causes and consequences of delayed diagnosis of cancer, and these data were supplemented with complete information on, eg, death, migration, health care utilization, medication use, and socioeconomic data from Denmark's comprehensive health and administrative registers. The cohort is followed up in terms of emigration, death, hospitalization, medication, and socioeconomics, and data are updated regularly. Results: In total, we identified 22,169 verified incident cancer cases. Completed GP questionnaires were returned for 17,566 (79% of the verified cases, and patient questionnaires were completed by 8,937 (40% respondents. Patients with participating GPs did not differ from patients with nonparticipating GPs in regard to one-year survival, comorbidity, or educational level. However, compared with nonparticipating GPs, patients listed with participating GPs were more likely to be women, younger, to have a higher disposable income, to have more regional or distant spread of tumors, were also more likely to have

    People living with HIV/AIDS (PLWHA) are surviving longer, with an increased risk of cancer. Cancer screening strategies in PLWHA are lacking. We describe the case of a woman with a history of AIDS, who had a nondetectable viral load on treatment. She is an activist, promoting HIV care, but had not undergone routine screening for breast, cervical, or colonic neoplasia. She presented with a left groin mass, which on biopsy proved to be a p16 immuno-histochemical positive squamous cell carcinoma. Anal and cervicovaginal examinations did not show invasive cancer, although high-resolution anoscopy identified high-grade anal dysplasia. A mammogram followed by magnetic resonance imaging showed invasive ductal carcinoma. Her breast cancer was treated with lumpectomy, adjuvant brachytherapy and chemotherapy. The left groin tumor was treated with chemo-radiation. Herein, we also review medical literature concerning anal, cervical, breast, colorectal, and lung cancer screening for PLWHA, which is important for our aging population of PLWHA. PMID:26864079

    Purpose: To identify the prognostic value of biological markers at initial operation for metastatic breast cancer, we measured the presence of estrogen receptor-alpha (ERα), progesterone receptor (PgR) and human epidermal growth factor receptor type 2 (HER2),and histological grade (HG) of tumors. Methods: One-hundred and seventy-six patients, aged 29 to 90 (median: 51 years), with recurrent breast cancer underwent primary operation at our department during the period from 1983 to 2000. Clinicopathological factors examined at primary operation included menopausal symptoms, presence of axillary lymph node metastasis, tumor size, HG, HER2, ERα and PgR.Factors examined at recurrence included site of primary recurrence, disease-free interval(DFI) and tumor markers, such as CEA and CA15-3. The relationship between these factors and prognosis following recurrence was assessed. Results: Menopausal status, axillary lymph node metastasis and tumor size at primary operation had no significant effect on prognosis. Patients with low HG, positive expession of ERα and PgR, and low HER2 expression had a good prognosis, similar to those with long DFI and distant metastases. After distant metastases, HER2 was found to be the most important prognostic factor following recurrence and in predicting response to drug therapy.Conclusion: Biological factors indicating tumor malignancy at the time of the first operation are also important prognostic factors following tumor recurrence.
