    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).

    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.

Epothilones are microtubule-stabilizing agents that inhibit cell growth. Currently, patupilone and its four synthetic derivatives ixabepilone, BMS-310705, sagopilone, 20-desmethyl-20-methylsulfanyl epothilone B and epothilone D, as well as its derivative KOS-1584, are under clinical evaluation. This is the first systematic review conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines that synthesizes all available data emerging from trials and evaluates the efficacy and safety of epothilones in epithelial ovarian, primary fallopian tube, and primary peritoneal cancer. Despite the fact that epothilones have proven active in taxane-resistant settings in preclinical models, it is not yet clear from Phase II/III studies reviewed here that their clinical activity is superior to that of taxanes. Nevertheless, responses to epothilones have been observed in platinum-refractory/resistant ovarian cancer patients. Moreover, despite the shared mechanism of action of epothilones, their clinical profile seems clearly different, with diarrhea being the most common dose-limiting toxicity encountered with patupilone, whereas neutropenia and sensory neuropathy are the most common toxic effects observed with the other epothilones. In any case, randomized trials comparing epothilones with standard treatments seem warranted to define further the role of these agents, whereas biomarker analysis might further optimize patient selection.

    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.

    Background Peritoneal tuberculosis and primary peritoneal carcinoma can both present as an abdominal mass and ascites with elevated serum CA125.The purpose of our study was to evaluate the clinical features of peritoneal tuberculosis,compare them with features of primary peritoneal carcinoma,and establish definitive diagnostic procedures.Methods We conducted a retrospective study in patients with peritoneal tuberculosis from January 1995 to October 2010 at Peking Union Medical College Hospital.During this time,the data of 38 patients with primary peritoneal carcinoma were reviewed.Results The median age was 34 years (range,19-80 years).The most common symptoms were abdominal distension (16/30,53.3%) and an abdominal mass (12/30,40.0%).The serum CA125 level was elevated in 25 patients (83.3%).The median level of cancer antigen CA125 was 392.5 U/ml (range,0.64-850.0 U/ml).Abdominal ultrasound revealed a pelvic mass in 25 patients and ascites in 20 patients.Diagnostic laparoscopy was performed in 15 patients (50.0%) and exploratory laparotomy was performed in 12 patients (40.0%),and 3 patients (10.0%) who underwent laparoscopy converted to laparotomy because of severe adhesions.The intraoperative findings were adhesions,multiple white tubercles,and ascites.Frozen tissue sections were obtained in 17 patients,and 14 of whom showed chronic granulomatous reactions.Final pathological examinations confirmed the diagnosis.Conclusions Peritoneal tuberculosis should be considered as a differential diagnosis,especially for young women with an abdominal mass,ascites,and elevated serum CA125 levels.Laparoscopy is a useful diagnostic method for peritoneal tuberculosis,and intraoperative frozen sections are recommended when the diagnosis is in doubt.

    Primary peritoneal carcinoma (PPC) is a type of rare malignant epithelial tumor. Metastasis from PPC to breast has been rarely reported. PPC originates de novo from the peritoneal tissues rather than invasion or metastasis from adjacent or remote organs. PPCs have been implicated in many cases of carcinomas of unknown primary origin. It is similar to ovarian cancer (OvCa), because it shares the same common embryonic origin, the coelomic epithelium (mesodermal origin). The mechanism of oncogenesis remains elusive. In this article, we report a rare case of PPC in a patient 10 years after total abdominal hysterectomy and bilateral salpingooophorectomy for uterine leiomyoma, which was widely spread in the abdomen and metastasized to the colon, liver and distant organs including breast. The treatment is similar to that of primary ovarian cancer. We also reviewed the primary peritoneal cancer metastatic to breast and discuss the possible mechanisms and biology of primary peritoneal cancer, using experimental and animal model.

  6. 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.

    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.)

    AIM: To evaluate the role of peritoneal lavage cytology (PLC) and carcinoembryonic antigen (CEA) determination of peritoneal washes (pCEA) in predicting the peritoneal metastasis and prognosis after curative resection of gastric cancer.METHODS: PLC and radioimmunoassay of CEA were performed in peritoneal washes from 64 patients with gastric cancer and 8 patients with benign diseases.RESULTS: The positive rate of pCEA (40.6%) was significantly higher than that of PLC (23.4%) (P<0.05).The positive rates of PLC and pCEA correlated with the depth of tumor invasion and lymph node metastasis (P<0.05). pCEA was found to have a higher sensitivity and a lower false-positive rate in predicting peritoneal metastasis after curative resection of gastric cancer as compared to PLC. The 1-, 3-, and 5-year survival rates of patients with positive cytologic findings or positive pCEA results were significantly lower than those of patients with negative cytologic findings or negative pCEA results (P<0.05). Multivariate analysis indicated that pCEA was an independent prognostic factor for the survival of patients with gastric cancer.CONCLUSION: Intraoperative pCEA is a more sensitive and reliable predictor of peritoneal metastasis as well as prognosis in patients with gastric cancer as compared to PLC method.

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...

    2014-01-01

    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.

    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 torsion of ovarian cyst that underwent Laparotomy with cyst excision and postoperative Albendazole therapy.

    Full Text Available Primary adenocarcinoma of the appendix is rare, especially the colonic type. We report a case of appendiceal adenocarcinoma of colonic type associated with perforating peritonitis after aorto-femoral artery bypass surgery. A 79-year-old woman presented with fever and pain in the right lower abdomen. She had undergone aorto-femoral artery bypass surgery due to arteriosclerosis obliterans 6 months earlier. Abdominal ultrasonography and computed tomography showed a suspected pool of fluid surrounding the artificial vessel and a mass lesion in the upper end of the fluid collection. These findings suggested localized peritonitis due to appendiceal perforation. Emergency laparotomy showed a pool of pus around the artificial vessel and inflamed appendix, which adhered to the surrounding tissue. The mass was excised in combination with an ileocaecal resection, followed by an ileocolic anastomosis. The histological diagnosis was moderately differentiated adenocarcinoma of the appendix, colonic type. The tumour had infiltrated and obstructed the lumen of the orifice of the appendix, which may have caused perforation of the appendix. She was examined at regular periodic follow-ups and no evidence of recurrence or metastasis was noted in the 12-month postoperative period. These findings indicate that, in cases of acute appendicitis, especially with perforation, the possibility of appendiceal adenocarcinoma should be considered.

    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.

  1. 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.

    AIM:To investigate the immunological repertoire in the peritoneal cavity of gastric cancer patients.METHODS:The peritoneal cavity is a compartment in which immunological host-tumor interactions can occur.However,the role of lymphocytes in the peritoneal cavity of gastric cancer patients is unclear.We observed 64 patients who underwent gastrectomy for gastric cancer and 11 patients who underwent laparoscopic cholecystectomy for gallstones and acted as controls.Lymphocytes isolated from both peripheral blood and peritoneal lavage were analyzed for surface markers of lymphocytes and their cytokine production by flow cytometry.CD4+CD25high T cells isolated from the patient's peripheral blood were co-cultivated for 4 d with the intra-peritoneal lymphocytes,and a cytokine assay was performed.RESULTS:At gastrectomy,CCR7-CD45RA CD8+ effector memory T cells were observed in the peritoneal cavity.The frequency of CD4+ CD25 high T cells in both the peripheral blood and peritoneal cavity was elevated in patients at advanced stage [control vs stage Ⅳ in the peripheral blood:6.89 (3.39-10.4) vs 15.34 (11.37-1931),P < 0.05,control vs stage Ⅳ in the peritoneal cavity:8.65 (5.28-12.0) vs 19.56 (14.81-24.32),P < 0.05].On the other hand,the suppression was restored with CD4+ CD25highT cells from their own peripheral blood.This study is the first to analyze lymphocyte and cytokine production in the peritoneal cavity in patients with gastric cancer.Immune regulation at advanced stage is reversible at the point of gastrectomy.CONCLUSION:The immunological milieu in the peritoneal cavity of patients with advanced gastric cancer elicited a Th2 response even at gastrectomy,but this response was reversible.

    Full Text Available The aim of the present study was to determine the efficacy of a hypotonic treatment for peritoneal dissemination from gastric cancer cells using an in vivo model. We firstly evaluated the toxicity of a peritoneal injection of distilled water (DW (2 mL for 3 days in mice. Macroscopic and microscopic examinations revealed that the peritoneal injection of DW did not severely damage the abdominal organs of these mice. MKN45 gastric cancer cells preincubated with NaCl buffer or DW for 20 minutes in vitro were then intraperitoneally injected into nude mice, and the development of dissemination nodules was analyzed. The total number, weight, and volume of the dissemination nodules were significantly decreased by the DW preincubation. We then determined whether the peritoneal injection of DW inhibited the establishment of peritoneal dissemination. After a peritoneal injection of MKN45 cells into nude mice, NaCl buffer or DW was injected into the abdominal cavity for 3 days. The total volume of dissemination nodules was significantly lower in DW-injected mice than in NaCl-injected mice. In conclusion, we demonstrated the safeness of a peritoneal injection of DW. Furthermore, the development of dissemination nodules from gastric cancer cells was prevented by a preincubation with or peritoneal injection of DW.

    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.

  15. Association between Rash and a Positive Drug Response Associated with Vinorelbine in a Patient with Primary Peritoneal Carcinoma

    Directory of Open Access Journals (Sweden)

    Mustafa M. Mohammad

    2013-01-01

    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.

    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 Abstract Background Recently, excellent results are reported on laparoscopic lavage in patients with purulent perforated diverticulitis as an alternative for sigmoidectomy and ostomy. The objective of this study is to determine whether LaparOscopic LAvage and drainage is a safe and effective treatment for patients with purulent peritonitis (LOLA-arm and to determine the optimal resectional strategy in patients with a purulent or faecal peritonitis (DIVA-arm: perforated DIVerticulitis: sigmoidresection with or without Anastomosis. Methods/Design In this multicentre randomised trial all patients with perforated diverticulitis are included. Upon laparoscopy, patients with purulent peritonitis are treated with laparoscopic lavage and drainage, Hartmann's procedure or sigmoidectomy with primary anastomosis in a ratio of 2:1:1 (LOLA-arm. Patients with faecal peritonitis will be randomised 1:1 between Hartmann's procedure and resection with primary anastomosis (DIVA-arm. The primary combined endpoint of the LOLA-arm is major morbidity and mortality. A sample size of 132:66:66 patients will be able to detect a difference in the primary endpoint from 25% in resectional groups compared to 10% in the laparoscopic lavage group (two sided alpha = 5%, power = 90%. Endpoint of the DIVA-arm is stoma free survival one year after initial surgery. In this arm 212 patients are needed to significantly demonstrate a difference of 30% (log rank test two sided alpha = 5% and power = 90% in favour of the patients with resection with primary anastomosis. Secondary endpoints for both arms are the number of days alive and outside the hospital, health related quality of life, health care utilisation and associated costs. Discussion The Ladies trial is a nationwide multicentre randomised trial on perforated diverticulitis that will provide evidence on the merits of laparoscopic lavage and drainage for purulent generalised peritonitis and on the optimal resectional strategy

    This study examined the mechanism by which the gastric cancer cells lead to early peritoneal metastasis.HMrSV5 cells,a human peritoneal mesothelial cell line,were co-incubated with the supernatants of gastric cancer cells.Morphological changes of HMrSV5 cells were observed.The cell damage was quantitatively determined by MTT assay.The apoptosis of HMrSV5 cells was observed under transmission electron microscope.Acridine orange/ethidium bromidestained condensed nuclei was detected by fluorescent microscopy and flow cytometry.The expressions of Bcl-2 and Bax was immunochemically evaluated.The results showed that conspicuous morphological changes of apoptosis were observed in HMrSV5 cells 24 h after treatment with the supematants of gastric cancer cells.The supernatants could induce apoptosis of HMrSV5 cells in a time-dependent manner.Th esupematants could up-regulate the expression of Bax and suppress that of Bcl-2 in HMrSV5 cells.These findings demonstrated that gastric cancer cells can induce the apoptosis of HPMCs through supernatants in the early peritoneal metastasis.The abnormal expressions of Bcl-2 and Bax may contribute to the apoptosis.Anti-apoptosis drugs promise to be adjuvant chemotherapeutic agents in the treatment of peritoneal metastasis of gastric cancer.

  1. Adaptation of ovarian cancer cells to the peritoneal environment: Multiple mechanisms of the developmental patterning gene HOXA9

    Science.gov (United States)

    Ko, Song Yi; Naora, Honami

    2015-01-01

    The lethality of ovarian cancer stems from its propensity to involve the peritoneal cavity. However, the mechanisms that enable ovarian cancer cells to readily adapt to the peritoneal environment are not well understood. Here, we describe our recent studies in which we identified the mechanisms by which the transcription factor encoded by the patterning gene HOXA9 promotes the aggressive behavior of ovarian cancer. Firstly, we identified that HOXA9 promotes ovarian tumor growth and angiogenesis by activating the gene encoding transforming growth factor-β2 (TGF-β2), which in turn stimulates peritoneal fibroblasts and mesenchymal stem cells to acquire features of cancer-associated fibroblasts. Secondly, by inducing TGF-β2 and chemokine (C-C motif) ligand 2, HOXA9 stimulates peritoneal macrophages to acquire an immunosuppressive phenotype. Thirdly, HOXA9 stimulates attachment of ovarian cancer cells to peritoneal mesothelial cells by inducing expression of P-cadherin. By inducing P-cadherin, HOXA9 also enables floating cancer cells in the peritoneal cavity to form aggregates and escape anoikis. Together, our studies demonstrate that HOXA9 enables ovarian cancer cells to adapt to the peritoneal environment and ‘educates’ different types of stromal cells to become permissive for tumor growth. Our studies provide new insights into the regulation of tumor-stroma interactions in ovarian cancer and implicate several key effector molecules as candidate therapeutic targets. PMID:26000332

    ABSTRACT Peritoneal metastasis from gastric cancer is often undetectable by routine imaging studies. Even a microscopic metastasis detected only by cytologic examination of the peritoneal washes denotes a dismal prognosis, and surgery is ruled out as futile for patients who turn out to be cytology-positive by staging laparoscopy. On the other hand, recent developments in cancer chemotherapy have improved the outcome of the cytology-positive population to the point where a certain proportion o...

    Peritoneal washing is now part of the standard clinical practice in several abdominal and pelvic neoplasias. However, in colorectal cancer surgery, intra-peritoneal free cancer cells(IFCC) presence is not routinely investigated and their prognostic meaning is still unclear. When peritoneal washing results are positive for the presence of IFCC a worse outcome is usually expected in these colorectal cancer operated patients, but it what is not clear is whether it is associated with an increased risk of local recurrence. It is authors’ belief that one of the main reasons why IFCC are not researched as integral part of the routine staging system for colon cancer is that there still isn’t a diagnostic or detection method with enough sensibility and specificity. However, the potential clinical implications of a routine research for the presence IFCC in colon neoplasias are enormous: not only to obtain a more accurate clinical staging but also to offer different therapy protocols, based on the presence of IFCC. Based on this, adjuvant chemotherapy could be offered to those patients found to be positive for IFCC; also, protocols of proactive intraperitoneal chemotherapy could be applied. Although presence of IFCC appears to have a valid prognostic significance, further studies are needed to standardize detection and examination procedures, to determine if there are and which are the stages more likely to benefit from routine search for IFCC.

    Disseminated signet ring cell carcinomas frequently arise from the stomach. However, primaries in the colon and rectum have also been reported. We present a 68 year old lady who presented with a change in her bowel habit. Colonoscopy showed a stenosing rectal tumour at 7 cm to 8 cm from the anal verge. Multiple scattered ulcers were also noted along the entire length of the colon. Biopsy of the lesions revealed signet ring cell adenocarcinoma. Gastroscopy showed multiple nodules with ulceration over several areas of the stomach which were similar in appearance to the colonic lesions. However, no primary tumour of the stomach was seen. Biopsy of the gastric lesions also showed signet ring cell adenocarcinoma. Computed tomography scan of the abdomen and pelvis revealed circumferential tumour at the rectosigmoid junction with possible invasion into the left ischiorectal fossa. The overall picture was that of a primary rectal signet ring cell carcinoma with peritoneal dissemination. The patient was referred for palliative chemotherapy in view of the disseminated disease. In the present report, we discuss this interesting pathological entity and review the role of various histolological techniques in helping to identify the primary tumor.

  7. Peritoneal carcinomatosis

    International Nuclear Information System (INIS)

    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.)

    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 dire...

  9. Comparison of peritoneal free gastric cancer cells' detecting rates between laparoscopically assisted and open radical gastrectomy

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective: To compare laparoscopic gastrectomy and conventional surgery on the dissemination and seeding of tumor cells. Methods:Intraoperative peritoneal lavage cytologic examination was performed in 65 patients with gastric cancer, during laparoscopic gastrectomy (n=34) and conventional surgery (n=31). Cytology was examined twice, immediately after opening the peritoneal cavity and just before closing the abdomen. Saline was poured into the peritoneal cavity, and 100 ml fluid was retrieved after irrigation. Laparoscopic instruments were lavaged after surgery with 100 ml saline. Carbon dioxide (CO2) was derived through the trocar side orifice after pneumoperitoneum during laparoscopic gastrectomy and filtered through 100 ml saline. Cytologic examination of the filtrate was performed after the filtration process. Results: The incidence of positive cytology during laparoscopic surgery was 32.26% in the preoperative lavage and 22.58% in the postoperative lavage. The incidence of positive cytology during conventional surgery was 41.18% before lavage and 26.47% after lavage. Only one positive cytology was detected in the CO2 filtrate gas. The incidence of positive cytology in the lavage of the instruments during laparoscopic surgery was 6.45%. Conclusion: During gastric laparoscopic surgery, CO2 pneumoperitoneum does not affect tumor cell dissemination and seeding. In this study, laparoscopic techniques used in gastric cancer surgery were not associated with a higher risk for intraperitoneal dissemination of cancer cells than the conventional surgery.

  10. 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

    Here, we report 2 patients with gastric cancer and peritoneal dissemination who were successfully treated with chemotherapy after undergoing treatment for an oncologic emergency caused by peritoneal dissemination. Case 1 involved obstruction of the sigmoid colon caused by peritoneal dissemination. After urgent colostomy, S-1/IP IV paclitaxel chemotherapy was introduced. The patient continued the therapy for 2 years and 2 months. Case 2 involved acute renal failure due to bilateral ureter obstruction and obstructive jaundice caused by peritoneal dissemination. This patient underwent emergency treatment consisting of Double-J ureteral stent insertion and endoscopic nasobiliary drainage. He was successfully started on chemotherapy with S-1/oxaliplatin/IP paclitaxel. He continued the therapy for 8 months without symptoms. Aggressive treatment might be effective for advanced gastric cancer showing oncologic emergency. PMID:26805263

    2015-01-01

    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.

    Tropomyosin-related receptor kinase B (TrkB) signaling, stimulated by brain-derived neurotrophic factor (BDNF) ligand, promotes tumor progression, and is related to the poor prognosis of various malignancies. We sought to examine the clinical relevance of BDNF/TrkB expression in colorectal cancer (CRC) tissues, its prognostic value for CRC patients, and its therapeutic potential in vitro and in vivo. Two hundred and twenty-three CRC patient specimens were used to determine both BDNF and TrkB mRNA levels. The expression of these proteins in their primary and metastatic tumors was investigated by immunohistochemistry. CRC cell lines and recombinant BDNF and K252a (a selective pharmacological pan-Trk inhibitor) were used for in vitro cell viability, migration, invasion, anoikis resistance and in vivo peritoneal metastasis assays. Tissue BDNF mRNA was associated with liver and peritoneal metastasis. Tissue TrkB mRNA was also associated with lymph node metastasis. The co-expression of BDNF and TrkB was associated with liver and peritoneal metastasis. Patients with higher BDNF, TrkB, and co-expression of BDNF and TrkB had a significantly poor prognosis. BDNF increased tumor cell viability, migration, invasion and inhibited anoikis in the TrkB-expressing CRC cell lines. These effects were suppressed by K252a. In mice injected with DLD1 co-expressing BDNF and TrkB, and subsequently treated with K252a, peritoneal metastatic nodules was found to be reduced, as compared with control mice. BDNF/TrkB signaling may thus be a potential target for treating peritoneal carcinomatosis arising from colorectal cancer.

    AIM: To evaluate the efficacy of telomerase activity assay and peritoneal lavage cytology (PLC) examination in peritoneal lavage fluid for the prediction of peritoneal metastasis in gastric cancer patients, and to explore the relationship between telomerase activity and proliferating cell nuclear antigen expression.METHODS: Telomeric repeated amplification protocol (TRAP)-enzyme-linked immunosorbent assay (ELISA) was performed to measure the telomerase activity in 60 patients with gastric cancer and 50 with peptic ulcer. PLC analysis of the 60 patients with gastric cancer was used for comparison. The proliferating cell nuclear antigen (PCNA) in gastric carcinoma was immunohistochemically examined.RESULTS: The telomerase activity and PLC positive rate in peritoneal lavage fluid from patients with gastric cancer was 41.7% (25/60), and 25.0% (15/60), respectively. The positive rate of telomerase activity was significantly higher than that of PLC in the group Of pT4 (15/16 vs 9/16, P < 0.05), P1-3 (13/13 vs 9/13, P < 0.05) and diffuse type (22/42 vs 13/42, P < 0.05). The patients with positive telomerase activity, peritoneal metastasis, and serosal invasion had significantly higher levels of average PCNA proliferation index (PI), (55.00 ± 6.59 vs 27.43 ± 7.72, 57.26 ± 10.18 vs 29.15 ± 8.31, and 49.82 ± 6.74 vs 24;65 ± 7.33, respectively, P < 0.05).CONCLUSION: The TRAP assay for telomerase activity is a useful adjunct for cytologic method in the diagnosis of peritoneal micrometastasis and well related to higher proliferating activity of gastric cancer. The results of this study also suggest a promising future therapeutic strategy for treating peritoneal dissemination based on telomerase inhibition.

  2. 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

    A 60-year-old woman underwent emergency operation for ileus due to rectosigmoid cancer. Intraoperative cytology and peritoneal dissemination were positive. After performing sigmoid colostomy, she underwent neoadjuvant radiation therapy (40 Gy)and eight courses of a XELOX and bevacizumab regimen. FDG-PET did not indicate FDG accumulation after chemoradiotherapy, thus, we performed low anterior resection. Peritoneal dissemination and washing cytology were negative in the second operation. Neoadjuvant chemoradiotherapy with XELOX and bevacizumab were useful for down staging in patients with advanced colorectal cancer.

    The microdistribution of therapeutic monoclonal antibodies within a tumor is important for determining clinical response. Nonuniform microdistribution predicts therapy failure. Herein, we developed a semiquantitative method for measuring microdistribution of an antibody within a tumor using in situ fluorescence microscopy and sought to modulate the microdistribution by altering the route and timing of antibody dosing. The microdistribution of a fluorescently-labeled antibody, trastuzumab (50-μg and 150-μg intraperitoneal injection (i.p.), and 100-μg intravenous injection (i.v.)) was evaluated in a peritoneal dissemination mouse model of ovarian cancer. In addition, we evaluated the microdistribution of concurrently-injected (30-μg i.p. and 100-μg i.v.) or serial (two doses of 30-μg i.p.) trastuzumab using in situ multicolor fluorescence microscopy. After the administration of 50-μg i.p. and 100-μg i.v. trastuzumab fluorescence imaging showed no significant difference in the central to peripheral signal ratio (C/P ratio) and demonstrated a peripheral-dominant accumulation, whereas administration of 150-μg i.p. trastuzumab showed relatively uniform, central dominant accumulation. With concurrent-i.p.-i.v. injections trastuzumab showed slightly higher C/P ratio than concurrently-injected i.p. trastuzumab. Moreover, in the serial injection study, the second injection of trastuzumab distributed more centrally than the first injection, while no difference was observed in the control group. Our results suggest that injection routes do not affect the microdistribution pattern of antibody in small peritoneal disseminations. However, increasing the dose results in a more uniform antibody distribution within peritoneal nodules. Furthermore, the serial i.p. injection of antibody can modify the microdistribution within tumor nodules. This work has implications for the optimal delivery of antibody based cancer therapies.

    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.

    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.

    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 Extragenital malignant mixed mesodermal müllerian tumors (MT are rare neoplasms with poor prognosis. Most of them affect women older than 60 years. We present here a case with primary peritoneal malignant mixed müllerian tumor occurring in a young woman who underwent previous hysterectomy and double oophorectomy secondary to a benign disease. We report on the clinical, pathological, and immunohistochemical features of this lesion, which was composed of a poorly differentiated epithelial component and multiple areas of chondromatous differentiation. Along with a brief review of previously reported literature about genital and extragenital MT, some concepts relevant to this case are discussed.

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

    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.

    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 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 m L 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/m2; IP PTX [without intravenous(IV) PTX],80 mg/m2; and IP PTX(with IV PTX),20 mg/m2.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.

    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.

    The nude mice injected with human gastric cancer cells (SGC-7901) in their peritoneums were chosen as the animal models of gastric cancer peritoneal dissemination in this research. The Raman spectra at 785nm excitation of both these nude mice which were in different tumor planting periods and the normal counterpart were taken in vivo in the imitate laparotomy. 205 spectra were collected. The spectra of different tissue types were compared and classified by Support Vector Machine (SVM) algorithm. Significant differences were showed between normal and malignant tissues. The gastric cancer nodules had lower Raman intensities at 870, 1330, 1450, and 1660cm-1, but higher at 1007, 1050, 1093 and 1209cm-1, compared with normal tissues. Additionally, the spectra of malignant tissues had two peaks around 1330 cm-1 (1297cm-1 and 1331cm-1), while the spectra of normal tissues had only one peak (1297cm-1). The differences were attributed to the intensities of the stretching bands of the nucleic acid, protein and water. These features could be used to diagnose gastric cancer. The Support Vector Machine (SVM) algorithm was used to classify these spectra. For normal and malignant tissues, the sensitivity, specificity and accuracy were 95.73%, 70.73% and 90.73%, respectively, while for different tumor planting periods, they were 98.82%, 98.73% and 98.78%. The experimental results show that Raman spectra differ significantly between cancerous and normal gastric tissues, which provides the experimental basis for the diagnosis of gastric cancer by Raman spectroscopy technology. And SVM algorithm can give the well generalized classification performance for the samples, which expands the application of mathematical algorithms in the classification.

    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.

    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

    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

    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.

  5. 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.

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

  7. 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

    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.

    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.

    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.

  15. 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.)

    Gastric metastases from lung adenocarcinoma arerare. Because gastric metastasis grossly resemblesadvanced gastric cancer, it is difficult to diagnose gastricmetastasis especially when the histology of the primarylung cancer is adenocarcinoma. We describe a case ofgastric metastasis from primary lung adenocarcinomamimicking Borrmann type Ⅳ primary gastric cancer.A 68-year-old man with known lung adenocarcinomawith multiple bone metastases had been experiencingprogressive epigastric pain and dyspepsia over one year.Esophagogastroduodenoscopy revealed linitis plasticalikelesions in the fundus of the stomach. Pathologicexamination revealed a moderately differentiatedadenocarcinoma with submucosal infiltration. Positiveimmunohistochemical staining for thyroid transcriptionfactor-1 (TTF-1) and napsin A (Nap-A) confirmed thatthe metastasis was pulmonary in origin. The patienthad been treated with palliative chemotherapy for thelung cancer and had lived for over fifteen months afterthe diagnosis of gastric metastasis. Clinicians should beaware of the possibility of gastric metastasis in patientswith primary lung adenocarcinoma, and additionalimmunohistochemical staining for Nap-A as well as TTF-1may help in differentiating its origin.

  17. Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy improves survival for patients with peritoneal carcinomatosis from colorectal cancer: a phase II study from a Chinese center.

    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.

    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. 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; 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.)

    Noonan, Erika M; Farrell, Timothy W

    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.

  2. 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

    AIM: To evaluate the value of right trisectionectomy,previously named right trisegmentectomy, in the treatment of primary liver cancer by summarizing our 13-year experience for this procedure.METHODS: Thirty three primary liver cancer patients undergoing right trisectionectomy from Apr. 1987 to Dec.1999 were investigated retrospectively. The impacts in survival of patients by cancerous biological behavior, such as tumor thrombi and satellite nodules, were discussed respectively. All right trisectionectomies were performed under normothermic interruption of porta hepatis at single time. Ultrasonic dissector (CUSA system 200) was used in dissection of hepatic parenchyma from Nov. 1992, instead of finger fracture.RESULTS: 1-, 3- and 5-year survival rates were 71.9 %,40.6 % and 34.4 %, respectively. The longest survival term with free cancer was 150 months (alive). There were no significant differences in survival curves between cases with and without tumor thrombi (right branch of portal vein) and satellite nodules. Operative mortality was 3.0 % (1/33). Main surgical complications occurred in 5 cases.CONCLUSION: Right trisectionectomy should be regarded as an effective and safe procedure for huge primary liver cancers and is worth using more widely.

    Peritoneal involvement in colorectal cancer (CRC) is an adverse prognostic feature, which may prompt consideration of adjuvant chemotherapy in stage II disease. Controversies and challenges surrounding its assessment have led to consideration of peritoneal elastic lamina invasion (ELI) as an alternative marker of advanced local spread. The objectives of this study were (1) to evaluate the prognostic significance of peritoneal ELI in stage II CRC and (2) to determine the feasibility of ELI assessment in routine practice with the use of an elastic stain. Two hundred seventeen patients with stage II CRC (186, pT3; 31, pT4) were assessed for ELI and other established adverse histologic features. Of the pT3 tumors, 31 (16.7%) were ELI positive, 121 (65%) were ELI negative, and 34 (18.3%) lacked an identifiable elastic lamina. There were no significant differences in disease-free survival between pT3 ELI-negative and ELI-positive tumors (P = .517). The disease-free survival of pT4 tumors was significantly lower than that of pT3 ELI-negative tumors (P = .024) and pT3 ELI-positive tumors (P = .026), respectively. The elastic lamina was detected less frequently in right-sided pT3 tumors compared with left-sided tumors (65/91 [71.4%] versus 87/95 [91.6%], P ELI was not an adverse prognostic factor in this study. The frequent absence of an identifiable elastic lamina, particularly in right-sided tumors, may limit the use of ELI as a prognostic marker in CRC.

    The dialysate concentration of cancer antigen 125 (CA125) can be considered a reflection of mesothelial cell mass or turnover in stable continuous ambulatory peritoneal dialysis (CAPD) patients. The effect of dwell times exceeding 4 hours on CA125 appearance rate (CA125AR) is not known. Therefore, our objective in the present study was to analyze the effect of dwell time on CA125AR in stable CAPD patients. In 43 stable CAPD patients, we analyzed standard peritoneal permeability analyses (SPAs) performed with a 3.86% glucose dialysate, and night-dwell effluents from the night dwell prior to the SPA. Dialysate CA125 concentration was measured by radioimmunoassay (RIA II: Fujirebio Diagnostics, Malvern, PA, U.S.A.). Night-dwell CA125 correlated with the duration of the dwell (r = 0.32, p = 0.04) and with the CA125 concentration in the 4-hour dwell (r = 0.83, p < 0.001). The mean CA125AR in the SPA effluent was 97.8 +/- 46.3 U/min; in the overnight effluent, it was 108.8 +/- 73.7 U/min (nonsignificant). A good correlation was present between the CA125AR in the 4-hour dwells and in the overnight dwells (r = 0.82, p < 0.001). We conclude that using night dwells to regularly assess dialysate CA125--for instance, at every out-patient visit--is possible in CAPD patients, provided that appearance rate is calculated.

    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

  12. 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

    Directory of Open Access Journals (Sweden)

    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.

    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

  16. 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)

    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.

    This report presents the case of a 58-year-old man who was found to have foreign body granulomas (FBGs) that mimicked disseminated gastric cancer. The patient presented with a severe attack of acute upper abdominal pain, was admitted to the hospital, and thereafter underwent an immediate laparotomy due to a diagnosis of an upper gastrointestinal perforation. Follow-up endoscopy revealed an ulcer scar measuring 2 cm in size in the anterior wall of the middle stomach. The pathological examination of biopsy specimens taken around the scar revealed well to poorly differentiated adenocarcinoma. At the time of reoperation performed 2 months after the first operation, many small white granulomas were observed which were thought to be the result of peritoneal dissemination of the gastric cancer. However, both the cytology of the Douglas washing and pathological examination of frozen section specimens were negative for carcinoma, and therefore a distal gastrectomy was performed. The pathological examination revealed the presence of FBGs. In this rare case, the FBGs formed shortly after surgery and were difficult to distinguish from disseminated cancer.

  20. 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 Introduction Prediction of optimal cytoreduction in patients with advanced epithelial ovarian caner preoperatively. Methods Patients with advanced epithelial ovarian cancer who underwent surgery for the first time from Jan. to June 2008 at gynecologic oncology ward of TUMS (Tehran University of Medical Sciences were eligible for this study. The possibility of predicting primary optimal cytoreduction considering multiple variables was evaluated. Variables were peritoneal carcinomatosis, serum CA125, ascites, pleural effusion, physical status and imaging findings. Univariate comparisons of patients underwent suboptimal cytoreduction carried out using Fisher's exact test for each of the potential predictors. The wilcoxon rank sum test was used to compare variables between patients with optimal versus suboptimal cytoreduction. Results 41 patients met study inclusion criteria. Statistically significant association was noted between peritoneal carcinomatosis and suboptimal cytoreduction. There were no statistically significant differences between physical status, pleural effusion, imaging findings, serum CA125 and ascites of individuals with optimal cytoreduction compared to those with suboptimal cytoreduction. Conclusions Because of small populations in our study the results are not reproducible in alternate populations. Only the patient who is most unlikely to undergo optimal cytoreduction should be offered neoadjuvant chemotherapy, unless her medical condition renders her unsuitable for primary surgery.

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

    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

    Due to its increasing incidence and a grim prognosis, primary liver cancer remains a diagnostic and therapeutic challenge. For small localized tumors, surgical resection and liver transplantation are standard treatments with a curative-intent. Therapeutic options for locally advanced or metastatic diseases are limited. Globally, surgery fits less than 20% of patients. Early detection in high-risk patients and prevention of risk factors remain the key points in the standard care. External radiotherapy is a non invasive treatment with encouraging results for non operable patients. Emerging stereotactic radiotherapy yields high rates of local control without compromising toxicity. Tumors with bad prognostic factors could be cured with this approach. (authors)

  6. 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

  7. 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.

    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.

    Objective: To study the effects of circulation hyperthermic perfusion chemotherapy on tumor marker content and PI3K/Akt/mTOR pathway function of gastric cancer peritoneal effusion patients. Methods: 80 cases of gastric cancer peritoneal effusion patients in our hospital from May 2013 to August 2014 were enrolled and randomly divided into two groups. Observation group received circulation hyperthermic perfusion chemotherapy; control group received conventional perfusion chemotherapy. Then blood tumor markers, LAG3 and HSP content, PI3K-AKT-mTOR signal molecules were assayed. Results:(1) tumor markers: DDK1, EXOSC2 contents and PGR ratio of observation group were lower than those of control group; PGI and PGII contents were higher than those of control group; (2) LAG3 and HSP contents: HSP27 and HSP90 contents of observation group were lower than those of control group; sLAG-3 content was higher than that of control group; (3) signal molecules: mRNA contents of PI3K, Akt and mTOR molecules of observation group were lower than those of control group. Conclusion: Circulation hyperthermic perfusion chemotherapy is helpful to kill tumor cells, reduce tumor marker releasing into blood, regulate LAG3 and HSP expression and inhibit PI3K/Akt/mTOR pathway function; it’s an ideal method for treating peritoneal effusion.

    The incidence of Sjögren syndrome (SS) in primary biliary cirrhosis (PBC) patients is high. The influence of SS on the clinical outcomes of PBC patients, however, remains unclear. Our study retrospectively collected data on PBC-only patients and PBC patients with concomitant SS (PBC-SS) to compare the clinical differences of long-term outcomes between them.A total of 183 patients were diagnosed with PBC from January 1999 to December 2014 at our hospital. Of these, the authors excluded patients with diabetes, hypertension, advanced liver cirrhosis at initial diagnosis of PBC (Child-Turcotte-Pugh classification score of ≥7) and other liver diseases (ie, alcoholic liver disease, alpha-antitrypsin deficiency, viral hepatitis, and primary sclerosing cholangitis), and autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Of the remaining 125 patients, 77 (61.6%) were PBC-only and 48 (38.4%) were PBC-SS patients.The mean follow-up duration was 8.76 years. During the observation period, the incidence of interstitial lung disease was higher in the PBC-SS group than in the PBC-only group (P = 0.005). The occurrence of spontaneous bacterial peritonitis was significantly different in PBC-SS patients than in PBC-only patients (P = 0.002). The overall survival was lower in PBC-SS patients than in PBC-only patients (P = 0.033). Although the incidence of hepatocellular carcinoma, end-stage renal disease, variceal bleeding, and hypothyroidism were all higher in the PBC-SS group than in the PBC-only group, the differences were not significant.Our study suggests that PBC-SS patients have a higher risk of developing interstitial lung disease and spontaneous bacterial peritonitis and have a poor prognosis. Aggressive surveillance of thyroid and pulmonary functions should therefore be performed in these patients.

    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.

    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

    Full Text Available Accurately distinguishing serosal invasion in patients with gastric cancer (GC prior to surgery can be difficult. Molecular analysis of peritoneal fluid (MAPF for free cancer cells with higher sensitivity than other methods; however, its prognostic value for GC remains controversial, precluding its application in clinical practice.PubMed, EMBASE and other databases were systematically searched. Thirty-one studies were eligible for the meta-analysis. Hazard ratios (HRs and 95% confidence intervals (CIs were pooled for overall survival (OS, disease-free survival (DFS and peritoneal recurrence-free survival (PRF.The current meta-analysis focused on patients with GC and negative cytological diagnoses. The results showed that positive MAPF status (MAPF+ led to poorer prognoses for OS (HR 2.59, 95% CI 1.99-3.37, DFS (HR 4.92, 95% CI 3.28-7.37 and PRF (HR 2.81, 95% CI 2.12-3.72 compared with negative MAPF status (MAPF-. Moreover, among the patients with GC who received curative treatment, the MAPF+ patients had poorer prognoses for OS (HR 3.27, 95% CI 2.49-4.29, DFS (HR 3.90, 95% CI 2.74-5.57 and PRF (HR 5.45, 95% CI 3.70-8.03. A meta-analysis of multivariate-adjusted HRs demonstrated that MAPF+ status was an independent prognostic factor for patients with GC who underwent curative treatment (OS: HR 2.19, 95% CI 1.47-3.28; PRF: HR 3.44, 95% CI 2.01-5.87. Using the identical target genes (CEA, CEA/CK20 as molecular markers, the patients with GC who were MAPF+ had significantly worse prognoses for OS (CEA: HR 3.03, 95% CI 2.29-4.01; CEA/CK20: HR 4.24, 95% CI 2.42-7.40, DFS (CEA: HR 3.99, 95% CI 2.24-7.12; CEA/CK20: HR 4.31, 95% CI 1.49-2.48 and PRF (CEA: HR 4.45, 95% CI 2.72-7.31; CEA/CK20: HR 6.46, 95% CI 3.62-11.55 than the patients who were MAPF-.The above results demonstrate that MAPF could be a prognostic indicator for patients with GC who have a negative cytological diagnosis and/or are receiving curative treatment.

    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.

    Authors retrospectively analyzed the CT findings of 102 cases of histologically proven bronchogenic carcinoma during last 4 years from January 1980 to July 1984 at Kosin Medical College. The results were as follows: 1. The sex ratio was 86 males to 16 females and the greatest number (66.7%) of cases were seen in fourth and fifth decades. 2. The distribution of histologic types of primary lung cancer as follows: Squamous cell carcinoma 66 cases, Adenocarcinoma 10 cases, Small cell carcinoma 7 cases, Large cell carcinoma 5 cases, Bronchioloalveolar cell carcinoma 1 case, Unclassified 13 cases. 3. Location of primary lesions as follows: Right lung 61 cases, Left lung 40 cases. In both lungs, the greatest number of cases were found in the upper lobes. Ratio between central and peripheral mass was 2.5:1, except adenocarcinoma (6:4). 4. CT findings were as follows: Hilar or central mass (75 cases), Peripheral mass (26), Bronchial abnormalities such as narrowing, obstruction, or displacement (60), Thickening of the posterior wall of the right upper lobe bronchus, bronchus intermedius, or left main bronchus (17), Post-obstructive changes; Atelectasis, Pneumonitis, Emphysema (34, 17, 1 respectively), Hilar adenopathy (21), Mediastinal lymph node enlargement (50), Mediastinal invasion (51), Pericardial thickening (5), SVC syndrome with collateral vessels (3), Pleural effusion (27), Pleural thickening or invasion (14), Chest wall invasion (2), Distant metastasis (26). 5. In most of patients (92 cases), the size of mass was above 3cm, but in 9 cases below 3cm. Margins of the masses were serrated or lobulated in most cases. In 5 cases, cavitary formations were noted, walls of which were thick and irregular, and air-fluid level was noted in 1 case. In 2 cases, eccentric calcification were noted within mass. 6. Among 51 cases of whom direct mediastinal invasion was suspected, 8 cases were operated upon, and this revealed that the masses were not resectable. Among the patients in

  1. 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

    Abstract Double primary liver cancer (DPLC) is a special type of clinical situation. As such, a detailed analysis of the surgical management and prognosis of patients with DPLC is lacking. The objective of the current study was to define the management and outcome of patients undergoing surgery for DPLC at a major hepatobiliary center. A total of 87 patients treated by surgical resection at the Eastern Hepatobiliary Surgery Hospital from January 1st, 2007 to October 31st, 2013 who had DPLC demonstrated by final pathological diagnosis were identified. Among these, 50 patients had complete clinical and prognostic data. Demographic and tumor characteristics as well as the prognosis were analyzed. The proportion of hepatitis B surface antigen (HBsAg) (+) and hepatitis B virus e antigen (HBeAg) (+), HBsAg (+), and HBeAg (−) hepatocirrhosis in all patients was 21.84%, 67.82%, and 63.22%, respectively. Incidental findings accounted for 58.62% of patients; among those who had symptoms, the main symptom was abdominal pain (31.03%). Nonanatomic wedge resection was the main operative approach (62.07%). Postoperatively, the main complications included seroperitoneum (11.49%), hypoproteinemia (10.34%), and pleural effusion (8.05%). Factors associated with disease-free survival (DFS) included intrahepatic cholangiocarcinoma (ICC) tumor size (P = 0.002) and use of postoperative prophylactic transcatheter arterial chemoembolization (TACE) treatment (P = 0.015). Meanwhile, hepatocellular carcinoma (HCC) size (P = 0.045), ICC size (P < 0.001), and liver function (including aspartate aminotransferase [P = 0.001] and r-glutamyl transferase [P < 0.001]) were associated with overall survival (OS). Hepatitis B virus (HBV)-related hepatitis or cirrhosis is also an important factor in the pathogenesis of DPLC and surgical treatment is safe for it with low complication rates. In addition, it is effective to prolong DFS that DPLC patients undergo postoperative

    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

    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.

  9. 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

    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 Objective. To analyze the impact of patients’ experience of care at their usual source of primary care on their choice of point of entry into cancer investigation process, time to diagnosis, and presence of metastatic cancer at time of diagnosis. Method. A questionnaire was administered to 438 patients with cancer (breast, lung, and colorectal between 2011 and 2013 in four oncology clinics of Quebec (Canada. Multiple regression analyses (logistic and Cox models were conducted. Results. Among patients with symptoms leading to investigation of cancer (n=307, 47% used their usual source of primary care as the point of entry for investigation. Greater comprehensiveness of care was associated with the decision to use this source as point of entry (OR = 1.25; CI 90% = 1.06–1.46, as well as with shorter times between first symptoms and investigation (HR = 1.11; p=0.05, while greater accessibility was associated with shorter times between investigation and diagnosis (HR = 1.13; p<0.01.  Conclusion. Experience of care at the usual source of primary care has a slight influence on the choice of point of entry for cancer investigation and on time to diagnosis. This influence appears to be more related to patients’ perceptions of the accessibility and comprehensiveness of their usual source of primary care.

    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.

    Primary sclerosing cholangitis (PSC) is a chronic, progressive disease characterized by inflammatory and fibrosing strictures of the biliary tree. PSC is associated with a high lifetime risk of hepatobiliary and colorectal cancers. The nature of the carcinogenic process in PSC is not well established. The lack of diagnostic methods for early detection and the limited therapeutic options for cholangiocarcinoma constitute a major challenge in the current handling of PSC patients. The article reviews the risk for cancer development in PSC and discusses surveillance strategies for PSC-associated cancers.

    2009-12-01

    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

  7. Primary prevention of colorectal cancer: lifestyle, nutrition, exercise.

    Science.gov (United States)

    Martínez, María Elena

    2005-01-01

    The past two decades have provided a vast amount of literature related to the primary prevention of colorectal cancer. Large international variation in colorectal cancer incidence and mortality rates and the prominent increases in the incidence of colorectal cancer in groups that migrated from low- to high-incidence areas provided important evidence that lifestyle factors influence the development of this malignancy. Moreover, there is convincing evidence from epidemiological and experimental studies that dietary intake is an important etiological factor in colorectal neoplasia. Although the precise mechanisms have not been clarified, several lifestyle factors are likely to have a major impact on colorectal cancer development. Physical inactivity and to a lesser extent, excess body weight, are consistent risk factors for colon cancer. Exposure to tobacco products early in life is associated with a higher risk of developing colorectal neoplasia. Diet and nutritional factors are also clearly important. Diets high in red and processed meat increase risk. Excess alcohol consumption, probably in combination with a diet low in some micronutrients such as folate and methionine, appear to increase risk. There is also recent evidence supporting a protective effect of calcium and vitamin D in the etiology of colorectal neoplasia. The relationship between intake of dietary fiber and risk of colon cancer has been studied for three decades but the results are still inconclusive. However, some micronutrients or phytochemicals in fiber-rich foods may be important; folic acid is one such micronutrient that has been shown to protect against the development of colorectal neoplasia and is currently being studied in intervention trials of adenoma recurrence. The overwhelming evidence indicates that primary prevention of colon cancer is feasible. Continued focus on primary prevention of colorectal cancer, in combination with efforts aimed at screening and surveillance, will be vital in

    A retrospective study was performed on 47 patients with primary malignant neoplasms of the parotid gland treated in our department between 1982 and 1999. Most of the patients were male and over age 40, and 23 patients were of stage IV in clinical classification. The most frequently observed histological type was adenocarcinoma (12 patients), and the next was adenoid cystic carcinoma (11 patients).

    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

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.

    Primary liver cancer, which includes hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and fibrolamellar HCC, is one of the most common malignancies and the third leading cause of cancer-associated mortality, worldwide. Despite the development of novel therapies, the prognosis of liver cancer patients remains extremely poor. Thus, investigation of the genetic background and molecular mechanisms underlying the development and progression of this disease has gained significant attention. The Notch signaling pathway is a crucial determinant of cell fate during development and disease in several organs. In the liver, Notch signaling is involved in biliary tree development and tubulogenesis, and is also significant in the development of HCC and ICC. These findings suggest that the modulation of Notch pathway activity may have therapeutic relevance. The present review summarizes Notch signaling during HCC and ICC development and discusses the findings of recent studies regarding Notch expression, which reveal novel insights into its function in liver cancer progression.

    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.

    HER2 is amplified/overexpressed in a subset of gastric and gastro-oesophageal junction cancers. Addition of anti-HER2 therapy has been shown to provide survival benefit in this setting. However, there are limited data assessing the concordance of HER2 status between primary and metastatic sites.A total of 113 samples from 43 paired primary and metastatic tumours were tested for HER2 status, by immunohistochemistry (IHC) for protein expression and silver in situ hybridisation (SISH) for gene amplification.Primary sites tested included endoscopic biopsies (n = 30) and resections (n = 24). Metastatic samples included lymph nodes (n = 29), peritoneal effusions (n = 21) and miscellaneous sites (n = 9). The overall HER2+ rate was 11%. Of 41 (95%; 95% CI 88.5-100%) concordant cases, 38 were HER2- and three were HER2+. There were two (5%) discordant cases, one of which showed heterogeneity of HER2 expression.This series confirms a high concordance rate of 95%, supporting that testing of primary tumours and metastases is equally valid and providing clinical rationale for the addition of anti-HER2 therapy in HER2+ disseminated disease.

    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.

    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.

    A 47-year-old Korean woman with right middle lobe lung adenocarcinoma, malignant pleural effusion, and multiple lymph node and bone metastases, after three months of lung cancer diagnosis, presented with a palpable right breast mass. Images of the right breast demonstrated architectural distortion that strongly suggested primary breast cancer. Breast biopsy revealed metastatic lung cancer with a negative result for estrogen receptor (ER), progesterone receptor (PR) and mammaglobin, and a positive result for thyroid transcription factor-1 (TTF-1). We present a case of breast metastasis from a case of lung cancer with an extensive micropapillary component, which was initially misinterpreted as a primary breast cancer due to unusual image findings with architectural distortion.

    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.

    Full Text Available Background: Limited information exists on primary care physicians’ (PCPs use of the prostate-specific antigen (PSA test by patient risk category. We describe PCP responses to hypothetical patient scenario (PS involving PSA testing among high-risk asymptomatic men. Methods: Data were from the 2007 to 2008 National Survey of Primary Care Physicians’ Practices Regarding Prostate Cancer Screening. PS#1: healthy 55-year-old white male with no family history of prostate cancer; PS#2: healthy 45-year-old African American male with no family history of prostate cancer; and PS#3: healthy 50-year-old male with a family history of prostate cancer. Data were analyzed in SAS/SUDAAN. Results: Most PCPs indicated that they generally discuss the possible benefits/risks of PSA testing with the patient and then recommend the test (PS#1-PS#3 range, 53.4%-68.7%; P < .001; only about 1% reported discussing and then recommending against the test. For PS#3, compared to PS#1 and #2, PCPs were more likely to discuss and recommend the test or attempt to persuade the patient who initially declines the test. For PS#3, all clinicians generally would order/discuss the PSA test and not rely on the patient to ask. Conclusion: Clinicians treat family history as an important reason to recommend, persuade, and initiate PSA testing.

  7. 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.

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.

    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.)

    We initiated a therapeutic program of continuous ambulatory peritoneal dialysis for patients with chronic renal failure. Our program resulted in many episodes of peritonitis arising from contamination due to the technical aspects of the procedure. Microbiologic evaluation showed that 73% of 97 episodes were culture positive, with gram-positive organisms causing most of the cases, especially early in dialysis. Gram-negative rods tended to occur later. Gram stains of dialysate effluent resulted in a disappointingly low yield of only 9% positivity. Cell counts were a dependable indicator of the presence of peritoneal inflammation and also of therapeutic success. Most patients responded well to intraperitoneal cephalothin, 125 mg/L for 10 to 14 d. The occurrence of peritonitis resulted in 0.93 years of hospitalization during the total of 15.45 patient-years on dialysis, which essentially negated the financial advantages of this method of treatment of chronic renal failure. For this to be a successful mode of therapy, advances in the prevention of peritonitis must be made. PMID:6985785

    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.

    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.

    The aim of the study was to investigate the efect of lipopolysaccharide (LPS) on the expression of nuclear factor kappa B (NF-κB) in 4-(methylitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-mediated primary mouse peritoneal macrophagesin vitro.Methods: The activity of peritoneal macrophages treated with diferent concentrations of LPS was de-tected by MTT assay in rider to find the optimal concentration. Peritoneal macrophages were also treated with NNK (100-500μM), with or without LPS for 9 h. The expression of NF-κB was demonstrated via immunocytochemistry (ICC) and Western-blot, respectively.Results:The concentration of LPS at 25 μg/mL was found to be the optimal concentration to improve the activity of peritoneal macrophages (P < 0.01). Simultaneously, LPS (25 μg/mL) increased the expression of NF-κB in both the nucleus and cytoplasm and facilitated transfer of NF-κB to the nucleus. NNK treatment significantly inhibited the expression of NF-κB in a concentration-dependent manner, among the LPS-stimulated or unstimulated peritoneal macrophages, espe-cialy when cotreated with LPS (25 μg/mL,P < 0.01 ). Furthermore, NNK treatment (500 μM) with LPS yielded a significant decrease in NF-κB translocation to nucleus and inhibited the expression of NF-κB (P < 0.005).Conclusion: LPS enhances the suppression of NF-κB expression in NNK-mediated mouse peritoneal macrophages, which may provide a theoretical basis for the inhibition of cancer.

    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.

    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 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.

  1. 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 Aim To investigate the presence and expression levels of the IL-18 in the primary breast cancer tissue in relation to the unchangedbreast tissue in same patients and the breast tissue in patients withbenign breast disease, as well as the correlation between the IL-18 expression levels and pathohistological factors, including thecorrelation between IL-18 expression and the estrogens and progesterone receptor status. Methods This prospective randomized study was conducted at the Policlinic for Laboratory Diagnostics of the University Clinical Centre of Tuzla. 50 patients with invasive ductal breast cancer and 20 patients with benign breast diseases were included in the study. The tree-step immunohistochemical staining was used for testing the levels of IL-18 expression and hormone receptor status. Results IL-18 was present in the breast cancer tumour, in the surrounding unchanged tissue of the same patients and in the breast tissue of patients with benign breast tumour and other benign breast disease. The expression of this interleukin was signiicantly higher in breast cancer tumour tissue as compared to its expression in surrounding unchanged tissue of the same patients (p<0,05, whereas IL-18 expression was not signiicantly higher in breast cancer tumours compared to its expression in breast tissue of the patients with benign breast diseases (p=0,057. There was no signiicant correlation between IL-18 expression and the lymph node status, and between IL-18 expression and the pathohistological factors. Conclusion The results suggest possible involvement of IL-18 in complex mechanisms of breast carcinogenesis.

    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.

    2016-08-01

    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

    According to the National Registry of Renal Replacement Therapy (RRT), the incidence of chronic kidney disease (end-stage renal disease) and the need of RRT have declined in the last decade renal. One of the reasons for this tendency certainly is transplantation as the best choice. However, transplant procedure has limitations in elderly patients due to the number of comorbidities. This study was designed as retrospective analysis of outcomes in patients treated with peritoneal dialysis for a period of eleven years. Patients were divided into those who had been assisted or unassisted. Out of 100 patients treated with peritoneal dialysis (PD), 77 completed the treatment, including 26 assisted and 51 unassisted patients. Peritonitis was recorded in 20 assisted and 26 unassisted patients. Peritonitis was more common in unassisted patients, who were more frequently lost from PD. Assisted PD could be a good and safe choice of RRT in this special group of patients.

    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.

The present report concerns a 61-year-old man, a chronic smoker, who presented to us with symptomatic adrenal insufficiency. He had no evidence of lung cancer during this visit. The primary lung cancer was only identified 12 weeks later. Additionally, his adrenals showed no evidence of metastasis. Hence his adrenal insufficiency had been a paraneoplastic manifestation of the lung cancer, and it had also preceded the primary by 12 weeks.

    Storm, H.H.

    1988-02-15

    Using data from the population-based Danish Cancer Registry, the relative risk (RR) of second primary cancer was assessed among 24,970 women with invasive cervical cancer (1943-1982) and 19,470 women with carcinoma in situ of the cervix. The analysis was stratified according to treatment with (+) and without (-) radiation. For all second primaries combined, a RR+ = 1.1 (95% confidence interval (CI) = 1.06-1.18) and a RR- = 1.3 (95% CI = 1.13-1.40) was observed after invasive cervical cancers and a RR+ = 3.5 (95% CI = 1.4-7.2) and RR- = 1.1 (95% CI = 0.7-1.6) following in situ cancer. The small overall excess of second primary cancer is accounted for by an increase of some cancers such as lung, bladder, and a concurrent decrease in others such as breast. Although not statistically different from nonirradiated, the RR increased with time since treatment among irradiated invasive cervical cancer patients in organs close to and at intermediate distance from the cervix, reaching a maximum after 30 or more years of follow-up (RR = 1.9; 95% CI = 1.4-2.5). Altogether, for these sites an excess of 64 cases per 10,000 women per year were attributable to radiation among survivors of 30+ years. The highest risks among long-term survivors were observed for the following: other genital organs (RR = 5.8; 95% CI = 1.8-13.0) bladder (RR = 5.5; 95% CI = 2.8-9.5), connective tissue (RR = 3.3; 95% CI = 0.4-12.0), stomach (RR = 2.5; 95% CI = 1.1-4.7) and rectum (RR = 2.4; 95% CI = 1.1-4.6). A significant deficit of risk for breast cancer (RR = 0.7, 95% CI = 0.6-0.8) was observed for 10+ years, may be attributable to the effect of ovarian ablation by radiotherapy.

    Objective: To expore the indications and safety of extended hepatectomy for primary liver cancer (PLC). Methods: From Nov. 2000 to Oct. 2002, 33 patients with PLC received extended hepatectomy, 26 of whom were complicated with liver cirrhosis. Preoperative findings, intraoperative management and the outcome of postoperative recovery were analyzed and evaluated. Results: Operative mortality was zero in this group and postoperative morbidity of complications was 33.3%, and all complications were cured after proper treatment. Conclusion: Extended hepatectomy for PLC was safe and viable for the patients who had enough reserve of liver function if the incised liver volume was less than 50% of the liver and the supporting treatment of the remnant liver was given as well as the postoperative complications were managed appropriately.

    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.

    The authors conducted a case-control study designed to evaluate the association between radiotherapy for a first primary cancer and subsequent leukemia risk. Study subjects were selected from four tumor registries (California, Connecticut, Kansas, and Massachusetts). Cases were subjects with two primary concers; the second cancer was a leukemia diagnosed one year or more after the diagnosis of the first primary cancer. Control subjects were patients with single cancers. Two control subjects were chosen for each case matched for tumor registry, site of the first primary cancer, date of diagnosis of the first primary cancer, age, sex, and duration of survival after the first primary cancer. Separate analyses were carried out for chronic lymphatic leukemia (166 cases) and all other leukemias (232 cases). The relative risk of chronic lymphatic leukemia after radiotherapy was 0.7 and did not differ significantly from unity. For all other leukemias, relative risks were 1.6 after radiotherapy for first primary cancers of all sites, 2.4 after radiotherapy to trunk sites, 2.2 after radiotherapy for breast cancer, and 10.3 after radiotherapy for cancer of the corpus uteri. These relative risks for leukemias other than chronic lymphatic leukemia all differed significantly from unity.

    Full Text Available Abstract Background To explain why rates of colorectal cancer (CRC screening including fecal occult blood testing (FOBT, flexible sigmoidoscopy (FS, colonoscopy (CS, and barium enema (BE, are low, this study assessed determinants of CRC screening from medical records. Methods Data were abstracted from patients aged ≥64 years selected from each clinician from 30 diverse primary care practices (n = 981. Measurements included the rates of annual FOBT, ever receiving FOBT, ever receiving FS/CS/BE under a combination variable, endoscopy/barium enema (EBE. Results Over five years, 8% had received annual FOBT, 53% had ever received FOBT and 22% had ever received EBE. Annual FOBT was negatively associated with female gender, odds ratio (OR = .23; 95% confidence interval = .12–.44 and positively associated with routinely receiving influenza vaccine, OR = 2.55 (1.45–4.47; and more office visits: 3 to Conclusion Overall CRC screening rates were low, but were related to the number of primary care office visits. FOBT was related to immunization status, suggesting the possible benefit of linking these preventive services.

    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 Abstract Introduction Acute hydrothorax is an uncommon but a well-recognized complication of peritoneal dialysis. No single test is definitive for diagnosis. Although it is not a life-threatening condition, hydrothorax often requires abandonment of peritoneal dialysis. Delay in diagnosis can lead to worsening of the clinical status. Case Presentation A 33-year-old Caucasian woman with lupus, who was successfully treated with temporary peritoneal dialysis 17 years previously, presented with acute dyspnea and a right pleural effusion after recommencing peritoneal dialysis. Investigations eliminated infective, cardiac, and primary respiratory causes. Peritoneal dialysis-related hydrothorax was suggested by biochemistry, and a pleuroperitoneal leak was definitively confirmed by using a Tc-99 m DTPA (diethylene triamine penta-acetic acid scintigraphy scan. Subsequently, she underwent video-assisted thoracoscopy-guided talc pleurodesis and was able to return successfully to peritoneal dialysis. Conclusion Although our case is not the first report that describes the occurrence of acute hydrothorax in peritoneal dialysis, it is an important condition to recognize for the wider general medical community. Furthermore, this case demonstrates that peritoneal dialysis can be continued with a hydrothorax, provided the underlying cause can be corrected. We review the literature pertaining to the utility and reliability of different diagnostic approaches to hydrothorax.

    Peritoneal encapsulation(PE) is a rare congenital malformation, characterized by a thin accessory peritoneal membrane which covers all or part of the small bowel, forming an accessory peritoneal sac. Most cases areasymptomatic and diagnosed incidentally during surgery and/or autopsy. Clinical presentation with intestinal obstruction is extremely rare and we report a case. A 25-year-old male, referred to emergency department with diffuse abdominal pain, crampy, with 8 h evolution, associated with nausea, vomiting and constipation in the last 48 h. The abdominal examination revealed an asymmetric and fixed distension, with hard consistency on palpation of lower abdominal quadrants. The abdominal radiography reveals a small bowel distension and fluid levels. Submitted to laparoscopic surgery that recourse to conversion because there is a total peritoneal encapsulation of the small bowel. After opening the peritoneal sac, we find a rotation of mesentery, at its root, conditioning twisting of small bowel and consequently occlusion. Uneventful postoperative with discharged at the 6th day. The PE is a very rare congenital anomaly characterized by abnormal bowel back into the abdominal cavity in the early stages of development.

    Background Peritoneal dissemination is the most common pattern of metastasis in advanced gastric carcinoma with serosal invasion. In the present study, we reported the clinical relevance of a new diagnostic method involving RT-PCR, using survivin as the target gene, for the detection of free cancer cells in peritoneal washes.Methods Intraoperative peritoneal washes were obtained from 48 patients who underwent surgery for gastric cancer. RT-PCR analysis with primers specific for survivin and conventional cytological examinations were both performed.Results Survivin mRNA was not detected in any peritoneal wash samples from patients with benign disease, but was detected in 28 of 48 samples taken from patients with gastric cancer and in all metastastic nodules. Survivin expression in the peritoneal cavity significantly correlated with depth of cancer invasion, lymph node metastasis, and TNM stage. There were 92% of clinically evident peritoneal metastasis cases showed detectable survivin expression. The combination of survivin RT-PCR and cytological examination yielded positive results in 66.7% (32/48) of patients with gastric cancer, much higher than the results produced by cytological method alone. Conclusions Survivin mRNA detected in peritoneal lavage fluid might indicate the presence of free cancer cells in the peritoneal cavity. The high sensitivity of the RT-PCR-based survivin assay suggests that survivin serves as a molecular marker for detecting peritoneal micrometastasis. Its ubiquitous expression in peritoneal cancer cells and metastatic nodules also suggests a promising future therapeutic strategy based on survivin inhibition for cases of gastric cancer involving peritoneal metastasis.

    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.

    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.

    We report a rare case of advanced carcinoma and a second primary carcinoma of the esophagus, both of which were successfully cured by chemotherapy and operation at different times. In 1991, a 38-year-old Japanese man was diagnosed with advanced esophageal cancer, which was unresectable because of the bronchial invasion of the tumor. He was given chemotherapy with cisplatin (CDDP), combined with radiotherapy. During a 4-year follow-up, neither regrowth of the primary tumor nor distant metastasis occurred. In 1995, esophagoscopy demonstrated a lugol-unstained region located 3 cm distal from the area of radiation to the primary lesion shown by esophagography. Histological examination of a biopsy specimen showed the mucosa to be normal. Nevertheless, yearly surveillance by endoscopy and histological examinations showed that the mucosa of the esophagus gradually began to demonstrate mild dysplasia, followed by severe dysplasia; in 1998, a diagnosis of squamous cell carcinoma was made. Esophagectomy with lymph node dissection was performed. Microscopic examination revealed that there had been pathologic complete response for the original advanced esophageal cancer. (author)

    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.

    Primary hepatic lymphoma (PHL) is a rare malignancy. We aimed to assess the clinical profile, outcome and prognostic factors in PHL through the Rare Cancer Network (RCN). A retrospective analysis of 41 patients was performed. Median age was 62 years (range, 23-86 years) with a male-to-female ratio of 1.9:1.0. Abdominal pain or discomfort was the most common presenting symptom. Regarding B-symptoms, 19.5% of patients had fever, 17.1% weight loss, and 9.8% night sweats. The most common radiological presentation was multiple lesions. Liver function tests were elevated in 56.1% of patients. The most common histopathological diagnosis was diffuse large B-cell lymphoma (65.9%). Most of the patients received Chop-like (cyclophosphamide, doxorubicin, vincristine, and prednisone) regimens; 4 patients received radiotherapy (dose range, 30.6-40.0 Gy). Median survival was 163 months, and 5- and 10-year overall survival rates were 77 and 59%, respectively. The 5- and 10-year disease-free and lymphoma-specific survival rates were 69, 56, 87 and 70%, respectively. Multivariate analysis revealed that fever, weight loss, and normal hemoglobin level were the independent factors influencing the outcome. In this retrospective multicenter RCN study, patients with PHL had a relatively better prognosis than that reported elsewhere. Multicenter prospective studies are still warranted to establish treatment guidelines, outcome, and prognostic factors. PMID:27746888

    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.

    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...

    Objective: To investigate the effects of TGF - β1 on tumour - mesothelial interaction. Methods; The level of various soluble factors were mesured. The expressions of TGF - β/Smad pathway related proteins were immu-nochemically evaluated. Results: The expression of TGF - β1 was significantly elevated in each gastric cancer cell line. Phosphorylated - Smad 2,3 expressions increased after gastric cancer cells treatment. Mesothelial cells exposed to gastric cancer cells became exfoliation and appeared injury,while blocking TGF - β1 partly inhibited these effects. Conclusion: TGF - β1, produced by cancer cells in peritoneal cavity affect the function and morphology of mesothelial cells so that the resulting environment becomes favorable for peritoneal metastases. TGF - β/Smad pathway may play an important role in above cascade. TGF - β1 inhibitor could partly inhibit these effects.%目的:研究胃癌分泌的转化生长因子-β1(TGF-β1)对腹膜的破坏机制及TGF-β1抑制剂对腹膜的保护.方法:ELISA法检测胃癌分泌上清中的相关细胞因子含量及在胃癌-腹膜相互作用中TGF-β-Smad信号通路蛋白的水平.观察TGF-β1抑制剂SB431542对腹膜癌转移的抑制作用.结果:5种胃癌细胞系均能分泌大量TGF-β1,TGF-β1的分泌量明显多于其他细胞因子.Western证实了TGF-β1及其信号通路TGF-β1/Smad2、3参与胃癌对间皮的损伤.胃癌上清能破坏间皮层,致损伤脱落,与TGF-β1共培养能明显影响间皮细胞生长.TGF-β1抑制剂SB431542可阻止胃癌上清对间皮的损伤.结论:胃癌上清中TGF-β1高表达,影响腹膜间皮形态与功能进而促进了癌转移,机制可能与Smad信号通路有关.TGF-β1抑制剂能减轻胃癌上清对间皮的损伤.

    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

  12. Response to microtubule-interacting agents in primary epithelial ovarian cancer cells

    Science.gov (United States)

    2013-01-01

    Background Ovarian cancer constitutes nearly 4% of all cancers among women and is the leading cause of death from gynecologic malignancies in the Western world. Standard first line adjuvant chemotherapy treatments include Paclitaxel (Taxol) and platinum-based agents. Taxol, epothilone B (EpoB) and discodermolide belong to a family of anti-neoplastic agents that specifically interferes with microtubules and arrests cells in the G2/M phase of the cell cycle. Despite initial success with chemotherapy treatment, many patients relapse due to chemotherapy resistance. In vitro establishment of primary ovarian cancer cells provides a powerful tool for better understanding the mechanisms of ovarian cancer resistance. We describe the generation and characterization of primary ovarian cancer cells derived from ascites fluids of patients with epithelial ovarian cancer. Methods Chemosensitivity of these cell lines to Taxol, EpoB and discodermolide was tested, and cell cycle analysis was compared to that of immortalized ovarian cancer cell lines SKOV3 and Hey. The relationship between drug resistance and αβ-tubulin and p53 status was also investigated. Results All newly generated primary cancer cells were highly sensitive to the drugs. αβ-tubulin mutation was not found in any primary cell lines tested. However, one cell line that harbors p53 mutation at residue 72 (Arg to Pro) exhibits altered cell cycle profile in response to all drug treatments. Immortalized ovarian cancer cells respond differently to EpoB treatment when compared to primary ovarian cancer cells, and p53 polymorphism suggests clinical significance in the anti-tumor response in patients. Conclusions The isolation and characterization of primary ovarian cancer cells from ovarian cancer patients’ specimens contribute to further understanding the nature of drug resistance to microtubule interacting agents (MIAs) currently used in clinical settings.

    Synchronous multiple primary lung cancer is uncommon. They present at the same time, but are distinct and have different histologic features. Synchronous triple primary lung cancer is rare and only few cases have been reported previously. We described a case of synchronous triple primary lung cancers in an asymptomatic 64-year-old man that showed different radiologic features of lung tumors on chest computed tomography images. Anatomical resection and histological analysis revealed 3 different types of lung carcinoma with radiologic-pathologic correlation.

  15. Multiple primary colorectal cancer: Individual or familial predisposition?

    2015-01-01

    Colorectal carcinoma(CRC) is one of the most frequent cancers. Along the surface of the large bowel, several foci of CRC may appear simultaneously or over the time. The development of at least two different tumours has been defined as multiple primary CRC(MPCRC):When more than one tumour is diagnosed at the same time, it is known as synchronous CRC(SCRC), while when a second neoplasm is diagnosed some time after the resection and/or diagnosis of the first lesion, it is called metachronous CRC(MCRC). Multiple issues can promote the development of MPCRC, ranging from different personal factors, such as environmental exposure, to familial predisposition due to hereditary factors. However, most studies do not distinguish this dichotomy. High- and low-pentrance genetic variants are involved in MPCRC. An increased risk for MPCRC has been described in Lynch syndrome, familial adenomatous polyposis, and serrated polyposis. Non-syndromic familial CRCs should also be considered as risk factors for MPCRC. Environmental factors can promote damage to colon mucosae that enable the concurrence of MPCRC. Epigenetics are thought to play a major role in the carcinogenesis of sporadic MPCRC. The methylation state of the DNA depends on multiple environmental factors(e.g., smoking and eating foods cooked at high temperatures), and this can contribute to increasing the MPCRC rate. Certain clinical features may also suggest individual predisposition for MPCRC. Different etiopathogenic factors are suspected to be involved in SCRC and MCRC, and different familial vs individual factors may be implicated. MCRC seems to follow a familial pattern, whereas individual factors are more important in SCRC. Further studies must be carried out to know the molecular basis of risks for MPCRC in order to modify, if necessary, its clinical management, especially from a preventive point of view.

    Objective To study the efficacy and safety of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) to treat rabbit model of gastric cancer with peritoneal carcinomatosis (PC).Methods VX2 tumor cells were injected into the gastric submucosa of 42 adult male New Zealand rabbits using a laparotomic implantation technique,to construct rabbit model of gastric cancer with PC.The rabbits were randomly divided into three groups:control group (n = 14),CRS group (n = 14),and CRS + HIPEC group (n = 14 ).The rabbits in control group were observed for natural course of disease progression.Treatments were initiated 8 or 9 days after inoculation of tumor cells,including optimal removal of tumor nodules in CRS group,and maximal removal of tumor nodules and heperthermic chemoperfusion in the CRS + HIPEC group with docetaxel (10 mg/rabbit ) and carboplatin (40 mg/rabbit) at 42 ℃ for 30 min.The primary endpoint was overall survival.The secondary endpoints were body weight,biochemistry,major organ functions and serious adverse events.Results The success rates of rabbit PC model were 100% (42/42).The clinicopathological feature of the model was similar to peritoneal carcinomatosis in human.Overall survival was 18-30 days ( median 24 days) in control group,20-40 days ( median 27 days) in CRS group,and 23-55 days ( median 46 days) in CRS plus HIPEC group ( CRS alone group VS control group,P > 0.05;CRS + HIPEC group vs pure CRS group,P < 0.01 ).As compared with CRS only or control groups,HIPEC could extend the overall survival by at least 70%.At the baseline,on the day of surgery and 7 days after surgery,the count of peripheral blood cells,liver and renal functions,and biochemistry parameters were all comparable.Serious adverse events occurred in 0 animal in control group,2 animals in CRS group including 1 animal died of anesthesia overdose and another 1died of postoperative hemorrhage,and 3 animals in CRS + HIPEC group including 1 animal died of

  17. 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

    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.

    Multiple or second primary lung cancers can develop at any sites in the lung with same or different histologic types, synchronously and/or metachronously. In case of metachronous occurrence of the second primary lung cancer, it is easy to confuse with the primary lung cancer as a recurrence of precedent lung malignancy treated successfully or metastasis. Previous reports have demonstrated that majority of the second primary lung malignancies have same histologic types regardless of their developing time and location. However, the repeated occurrence of the second primary lung malignancy, in particular with the different histologic features, is a very rare condition.A 62-year-old male who had past history of squamous cell carcinoma treated with surgery and adjuvant chemotherapy and the recurrence of lung malignancy on the trachea, which was also resected successfully visited our hospital due to blood tinged sputum. Evaluation using bronchoscopy and chest computed tomography revealed the tracheal mass looked similar grossly to the previous recurred tracheal mass that was resected surgically. Unexpectedly, the newly developed tracheal mass was confirmed as small cell lung cancer, the different histologic type from previous ones.In this report, we describe an interesting case of subsequent occurrence of second primary lung cancers showing histologic shifting at different sites in trachea, suggesting that it is important for physician to make an effort to identify the histologic characteristics of second primary lung cancers for the correct and adequate treatment no matter what they exhibit similar gross morphology.

    Patients who have had curative surgery for lung cancer are at the highest risk of developing a new lung cancer. Individual studies are usually underpowered to describe the clinical characteristics and outcomes in second primary lung cancer (SPLC). The goal of this study is to determine which treatment is best associated with survival in patients who develop a new primary lung cancer. All pathologically proven stage I lung cancer cases that received cancer-directed surgery included in the Surveillance Epidemiology and End Results database between 2004 and 2010 were selected. Cases that received radiation therapy were excluded. Cases that developed a SPLC 6 or more months after the diagnosis of the first cancer were analyzed. The original data set consisted of 9564 stage I lung cancer cases treated with surgery; 520 of them developed a second primary, and completed data were available for 494 of them. Stage I disease was diagnosed in 272 patients with SPLCs (58.5%); 45.8% of these underwent cancer surgery alone, and 31.6% received radiation alone. Surgery was performed more frequently in early stages and younger patients. Surgical patients had statistically significant longer survival than patients treated with radiation (log-rank P < 0.0001) or not treated with surgery or radiation (log-rank P < 0.0001). The incidence of SPLCs was 5.4%. Stage I second primaries had improved survival when compared with later stage disease, and surgery conferred an increased survival benefit as compared with radiation.

  2. 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

    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

    Full Text Available Tobacco, alcohol, and betel quid are the main causes of squamous cell cancers of the upper aerodigestive tract. These substances can cause multifocal carcinogenesis leading to multiple synchronous or metachronous cancers of the oesophagus, head and neck region, and lungs (‘field cancerisation’. Globally there are several million people who have survived either head and neck squamous cell cancer (HNSCC or lung cancer (LC. HNSCC and LC survivors are at increased risk of developing second primary malignancies, including second primary cancers of the oesophagus. The risk of second primary oesophageal squamous cell cancer (OSCC ranges from 8-30% in HNSCC patients. LC and HNSCC survivors should be offered endoscopic surveillance of the oesophagus. Lugol chromoendoscopy is the traditional and best evaluated screening method to detect early squamous cell neoplasias of the oesophagus. More recently, narrow band imaging combined with magnifying endoscopy has been established as an alternative screening method in Asia. Low-dose chest computed tomography (CT is the best evidencebased screening technique to detect (second primary LC and to reduce LC-related mortality. Low-dose chest CT screening is therefore recommended in OSCC, HNSCC, and LC survivors. In addition, OSCC survivors should undergo periodic pharyngolaryngoscopy for early detection of second primary HNSCC. Secondary prevention aims at quitting smoking, betel quid chewing, and alcohol consumption. As field cancerisation involves the oesophagus, the bronchi, and the head and neck region, the patients at risk are best surveilled and managed by an interdisciplinary team.

    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.

    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.

    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.

    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.

    Breast conserving surgery and irradiation is now accepted as preferable treatment method for the patients with stage I and II breast cancer. Our institution activated team approach for breast conservation 1991 and treated on hundred and forty patients during the next three years. Purpose: To present our early experience with eligibility criteria, treatment techniques, and the morbidities of primary radiotherapy. Materials and Methods: Sixty four patients with early stage breast cancer who received breast conserving treatment between January 1991 and December 1992 were evaluated. All patients received partial mastectomy(wide excision to quadrantectomy) and axillary node dissection followed by radiotherapy. Total dose of 4500-5040 cGy in 5-5 1/2 weeks was given to entire involved breast and boost dose of 1000-2000 cGy in 1-2 weeks was given to the primary tumor site. Linac 4 MV X-ray was used for breast irradiation and electron beam was used for boost. Thirty five patients received chemotherapy before or after radiotherapy. Patients characteristics, treatment techniques, and treatment related morbidities were analyzed. Results: Age distribution was ranged from 23 to 59 year old with median age of 40. Twenty-seven patients had T1 lesions and 34 patients had T2 lesions. In three patients, pathologic diagnosis was ductal carcinoma in situ. Thirty-seven patients were N0 and 27 patients were N1. There were three recurrences, one in the breast and two distant metastases during follow-up period(6-30 months, median 14 months). Only one breast recurrence occurred at undetected separate lesion with microcalcifications on initial mammogram. There was no serious side reaction which interrupted treatment courses or severe late complication. Only one symptomatic radiation pneumonitis and one asymptomatic radiation peumonitis were noted. Conclusions: Conservative surgery and primary radiotherapy for early breast cancer in proven to be safe and comfortable treatment method without

    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%.

    Full Text Available INTRODUCTION: Peritoneal carcinomatosis is a condition that may be present in the natural history of colorectal cancer and some other tumors, such as pseudomyxoma peritonei. It has been associated with poor prognosis. The treatment for patients with this condition, up until recently, was systemic chemotherapy or palliative care to relieve the pain and suffering caused by peritoneal dissemination of certain cancers. Promising results, however, have been reported after the implementation of radical cytoreductive surgery followed by peroperative hyperthermic intraperitoneal chemotherapy. OBJECTIVE: To evaluate the results of cytoreductive surgery and peroperative hyperthermic intraperitoneal chemotherapy (HIPEC in patients with peritoneal carcinomatosis secondary to colorectal cancer and pseudomyxoma peritonei. RESULTS: We retrospectively evaluated 24 patients from 2004 to 2011. Mean age was 51.31 years, and 54% were female. The primary diagnosis in 50.01% of the cases was pseudomyxoma peritonei, 41.66%, of colon cancer, and 8.33%, of mesothelioma. The overall complication rate was around 83%, two patients (8% subsequently died between the 8th and 30th postoperative day. There was an association between the peritoneal carcinomatosis index (PCI and operative time. The one-year survival rate in the group examined was 60% for colon cancer, and 78.5% for pseudomyxoma. Overall survival was 50% in three years. CONCLUSION: cytoreductive surgery combined with HIPEC is a treatment option for patients with peritoneal carcinomatosis of colorectal origin and pseudomyxoma. Despite the high rate of peroperative complications (83%, it was possible to achieve a superior survival rate in relation to conventional treatments reported in the literature.INTRODUÇÃO: A carcinomatose peritoneal é uma condição que pode estar presente na história natural do câncer colorretal e de algumas outras neoplasias, como o pseudomixoma peritoneal, sendo associada com um progn

    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.

    Full Text Available Cancer is a worldwide problem that is caused by a variety of different factors increasing over a number of years. Oral cancer is a very prevalent disease and one of the most 10 common causes of death. It is important that the risk factors can be controlled. 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 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.

    Full Text Available Abstract Although about 30% of gastric cancers have distant metastasis at the time of initial diagnosis, metastatic tumor embolus in the main blood vessels is not common, especially in the main artery. The report presents, for the first time, an extremely rare clinical case of a metastatic embolus in the common carotid artery (CCA from primary gastric cancer. Metastatic embolus from the primary tumor should be considered when patients present with gastric cancer accompanied by intravascular emboli. The patient should be actively examined further so as to allow early detection and treatment.

    2013-01-01

    Encapsulating peritoneal sclerosis (EPS) is a serious and often fatal complication of long-term peritoneal dialysis (PD) with severe malnutrition and poor prognosis. It causes progressive obstruction and encapsulation of the bowel loops. As EPS becomes more prevalent with longer duration of PD, large multicenter prospective studies are needed to establish its incidence and identify risk factors, therapeutic approach, and prognosis.

    Matrix metalloproteinases (MMPs) are enzymes thought to be involved in tumor invasion. We hypothesized that MMP-2 and MMP-11 overexpression was associated with the aggressiveness of ovarian carcinoma. This study was performed on samples from 100 patients with stage III ovarian carcinomas treated surgically between 1990 and 2000. Immunohistochemical staining was performed on ovarian tumors and peritoneal implants using monoclonal antibodies. Overexpression was defined as more than 10% of cells expressing the marker. Multivariate analyses showed that only MMP-2 overexpression by cancer cells in peritoneal implants was associated with a significant risk of death by disease (hazard ratio, 2.65; 95% confidence interval, 1.41-4.97; P =.003). MMP-11 overexpression was not predictive of survival. These results suggest that MMP-2 overexpression by cancer cells in peritoneal implants and not in the primary ovarian cancer is predictive of ovarian cancer prognosis and more likely reflects the presence of particularly aggressive clones of cancer cells.

  17. 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.

  18. Direct ChromOSOme Analysis and FISH Detection of Primary Gastric cancer

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objective: To investigate chromosome aberrations and their role in the genesis and development of primary gastric cancer. Methods: An improved, direct chromosome preparation from solid tumors was adopted for G-banding analysis followed by FISH on decolored G-banding chromosomes so that chromosome aberrations could be confirmed at DNA level. Results: A total of 28 primary gastric cancer specimens were studies. Case 1 and case 2 had simple chromosome numerical changes: 49, XY, +2, +8, +9 and 48, +8, +20, respectively. All but case 1 and 2 had complicated chromosome abnormalities. Chromosome structural of frequent occurrence involved del(7q)(21/26), del(3p)(14/26), del(lp)(l1/26) and del(17p)(10/26). The chromosome abnormalities could be simple and complicated. In former, numerical changes involving 1 to 3 chromosome could be observed. Trisomies 8 and 9 might represent a cytogenetic subgroup of primary gastric cancer. In the later, the del(7q) was the most consistent aberration. 7q32-qter was the commonly lost segment. Conclusion: Numerical and structural alterations of chromosomes are present in primary gastric cancer. Del(7q) is one of the structural change characteristic of primary gastric cancer. In the 7q32-qter fragment, a tumor suppressor gene probably exists and it may have close relation to the genesis and progression of gastric cancer.

    The present study was undertaken in order to assess bidirectional peritoneal kinetics of albumin after simultaneous i.v. and i.p. injection of radioiodinated albumin tracers (125I-RISA and 131I-RISA) in eight clinically stable uraemic patients undergoing continuous ambulatory peritoneal dialysis...... (CAPD). The plasma volume, intravascular albumin mass (IVM), and overall extravasation rate of albumin were not significantly different from that found in healthy controls. Albumin flux from the plasma into the peritoneal cavity was 3.71 +/- 0.82 (SD) mumol/h, which was only 3% of the overall...... extravasation rate (137 +/- 52 mumol/h). Albumin flux from the peritoneal cavity into the plasma was substantially lower (0.22 +/- 0.07 mumol/h, P peritoneal accumulation of the albumin from plasma over 4 h was 14 +/- 3.2 mumol, which was significantly lower than the intraperitoneal albumin...

    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.

  2. 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

    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.

    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

    Feline infectious peritonitis (FIP) frequently results in death in cats. It is caused by a mutated, highly contagious coronavirus, and it is more common in indoor cats in multicat households. A complex interaction between the coronavirus and the feline immune system causes disseminated vasculitis, which is the hallmark of FIP. New tests are being developed, but the antemortem diagnosis of FIP continues to be difficult and frustrating. Current treatments are crude and involve supportive care and immunosuppression. Minimizing exposure is the best method of preventing infection.

    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

    Full Text Available Background: Multiple studies have examined the incidence of secondary primary malignancies (SPM in gastric cancer patients in Europe and Asia. This retrospective review was conducted to analyze risk of SPM in patients with gastric cancer diagnosed in the United States (US.Methods: We included adult patients diagnosed with gastric cancer from the Surveillance, Epidemiology and End Result (SEER 13 database. We calculated the risk of secondary primary malignancies in these patients using the multiple primary standardized incidence ratio (MP-SIR session of SEER*stat software and performed subset analyses of SPM with regard to age, sex, radiotherapy used, and latency period.Results: Among 33,720 patients, 1838 (5.45% developed 2019 secondary primary malignancies with an observed/expected (O/E ratio of 1.11 (95% confidence interval (CI = 1.06-1.16, p<.001 and an absolute excess risk (AER of 18.16 per 10,000 population. The median time to first SPM from the time of diagnosis of gastric cancer was 46.9 months (range 6-239 months. Significant excess risk was observed for gastrointestinal malignancies [O/E ratio 1.71 (CI = 1.59-1.84, p<.001], thyroid [O/E ratio 2.00 (CI = 1.37-2.8, p<.001] and pancreatic cancer [O/E ratio 1.60 (CI = 1.29-21.96, p<.001].

    Colorectal cancer is one of the most frequent malignancies in the Czech Republic and worldwide. Also, a high prevalence of overweight and obesity, a high proportion of smokers in the population, and one of the highest per capita alcohol consumption rates are typical for the Czech population. The role of general practitioners in the prevention of colorectal cancer is crucial. In primary prevention, the doctor should emphasise the importance of a healthy lifestyle - a balanced diet rich in fruits and vegetables, maintaining a normal body weight, adequate physical activity, and non-smoking. In secondary prevention, patients should be informed about the possibilities of colorectal cancer screening and the benefits of early detection of the disease. Participation rates of the target population for colorectal cancer screening are low. Steps leading to increased participation in colorectal cancer screening (including postal invitations) play an important role in influencing the mortality of colorectal cancer.

    2012-05-01

    We assessed the sensitivity of positron emission tomography (PET) for detecting synchronous multiple primary cancers, particularly synchronous esophageal cancers in head and neck cancer patients. We retrospectively reviewed 230 head and neck cancer patients. All the patients routinely underwent the following examinations: urinalysis, occult blood, tumor marker detection [squamous cell carcinoma (SCC), cytokeratin fragment (CYFRA), and carcinoembryonic antigen (CEA)], esophagogastroduodenoscopy, colonoscopy (when CEA was high or occult blood was positive), abdominal ultrasonography, plain chest computed tomography (CT), and PET. Bronchoscopy was performed when CT revealed lung shadow of central region. Synchronous multiple primary cancers were detected in 42 (18.2%) patients. The diagnostic sensitivity of PET for synchronous primary cancers was as follows: esophagus, 7.6% (1/13); stomach, 25.0% (2/8); lung, 66.7% (4/6); head and neck, 75.0% (3/4); colon, 0% (0/1); kidney, 0% (0/1); and subcutaneous, 100% (1/1). The sensitivity of PET for detecting synchronous esophageal cancers is low because these are early-stage cancers (almost stage 0-I). Therefore, it is necessary to perform esophagogastroduodenoscopy for detecting synchronous esophageal cancers. PET is an important additional tool for detecting synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous head and neck cancer and lung cancer is high. But PET has the limitation of sensitivity for synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous esophageal cancer is very low.

  13. 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.)

  14. Choline PET and PET/CT in Primary Diagnosis and Staging of Prostate Cancer

    2012-01-01

    Full Text Available PET and PET/CT using [11C]- and [18F]-labelled choline derivates is increasingly being used for imaging of primary and recurrent prostate cancer. While PET and PET/CT with [11C]- and [18F]-labelled choline derivates in patients suffering from biochemical recurrence of prostate cancer has been examined in many studies that demonstrate an increasing importance, its role in the primary staging of prostate cancer is still a matter of debate.Morphological and functional imaging techniques such as CT, MRI and TRUS have demonstrated only limited accuracy for the diagnosis of primary prostate cancer. Molecular imaging with PET and PET/CT could potentially increase accuracy to localize primary prostate cancer. A considerable number of studies have examined the value of PET/CT with [11C]- and [18F]- labelled choline derivates for the diagnosis of primary prostate cancer with mixed results. Primary prostate cancer can only be detected with moderate sensitivity using [11C]- and [18F]choline PET and PET/CT. The detection rate depends on the tumour configuration. Detection is also limited by a considerable number of microcarcinomas that cannot be detected due to partial volume effects. Therefore small and in part rind-like tumours can often not be visualized. Furthermore, the differentiation between benign changes like prostatitis, high-grade intraepithelial neoplasia (HGPIN or prostatic hyperplasia is not always possible. Therefore, at the present time, the routine use of PET/CT with [11C]- and [18F]-labelled choline derivates cannot be recommended as a first-line screening procedure for primary prostate cancer in men at risk. A potential application of choline PET and PET/CT may be to increase the detection rate of clinically suspected prostate cancer with multiple negative prostate biopsies, for example in preparation of a focused re-biopsy and may play a role in patient stratification with respect to primary surgery and radiation therapy in the future.

    Introduction: 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 regula...

  17. Simultaneous Expression of Cancer Stem Cell-Like Properties and Cancer-Associated Fibroblast-Like Properties in a Primary Culture of Breast Cancer Cells

    International Nuclear Information System (INIS)

    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

    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.)

    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

    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.

    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. The case presented here is different from what has already been reported in literature, as the patient had no antecedent risk factors for renal squamous cell carcinoma.-------------------------------------------------Cite this article as: Pahwa M, Pahwa AR, Girotra M, Chawla A.

    Summary Background Although human papillomavirus detection in cervical lymph nodes of head and neck squamous cell cancers (HNSCC) of unknown primary site (UP) is indicative of a primary tumor of the oropharynx (OP), localization can remain elusive. Therefore, we investigated ultrasonography (US) for the identification of the primary tumor. Methods Eligible cases had HNSCC of UP after evaluation by a head and neck surgical oncologist. Controls were healthy volunteers. Transcervical and intraoral ultrasonography was performed by a standard protocol using convex (3.75–6.0 MHz and 5–7.5 MHz) transducers. US findings were compared with operative examination (exam under anesthesia, direct laryngoscopy) and biopsies. The primary outcome of interest was the presence or absence of a lesion on US. Results 10 cases and 20 controls were enrolled. PET/CT scans were negative/nonspecific (9), or suspicious (1) for a primary lesion. On US, predominantly hypoechoic (9 of 10) lesions were visualized consistent with base of tongue (n = 7) or tonsil (n = 3) primary tumors. On operative examination, 5 of 10 were appreciated. Two additional primaries were confirmed with biopsies “directed” by preoperative US. This represents an overall diagnostic rate of 70%, which is 20% higher than our detection rate for 2008–2010. The three cases in which a suspicious lesion was visualized on US, yet remained UP despite further interventions, could represent false positives, misclassification or operator variability. No lesions were suspected among the controls. Conclusion Ultrasound has promise for detection of UPs of the OP and therefore warrants further investigation. PMID:24819862

    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.

  9. “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

    Full Text Available Abstract Background Cancer of unknown primary site (CUP is considered an aggressive metastatic disease but whether the prognosis differs from metastatic cancers of known primary site is not known. Such data may give insight into the biology of CUP and the metastatic process in general. Methods 6,745 cancer patients, with primary metastatic cancer at diagnosis, were identified from the Swedish Cancer Registry, and were compared with 2,881 patients with CUP. Patients were diagnosed and died between 2002 and 2008. The influence of the primary site, known or unknown, on survival in patients with metastases at specific locations was investigated. Hazard ratios (HRs of death were estimated for several sites of metastasis, where patients with known primary sites were compared with CUP patients. Results Overall, patients with metastatic cancers with known primary sites had decreased hazards of death compared to CUP patients (HR = 0.69 [95% CI = 0.66–0.72]. The exceptions were cancer of the pancreas (1.71 [1.54–1.90], liver (1.58 [1.36–1.85], and stomach (1.16 [1.02–1.31]. For individual metastatic sites, patients with liver or bone metastases of known origin had better survival than those with CUP of the liver and bone. Patients with liver metastases of pancreatic origin had an increased risk of death compared with patients with CUP of the liver (1.25 [1.06–1.46]. The median survival time of CUP patients was three months. Conclusions Patients with CUP have poorer survival than patients with known primaries, except those with brain and respiratory system metastases. Of CUP sites, liver metastases had the worst prognosis. Survival in CUP was comparable to that in metastatic lung cancer. The aggressive behavior of CUP may be due to initial immunosuppression and immunoediting which may allow accumulation of mutations. Upon escape from the suppressed state an unstoppable tumor spread ensues. These novel data on the epidemiology of the

    We present a 13-year-old girl with Arnold-Chiari syndrome and uremia secondary to neurogenic bladder. She had been treated with continuous ambulatory peritoneal dialysis (CAPD) for 13 months prior to the development of peritonitis. The patient demonstrated no improvement with a 3-day therapy of intraperitoneal vancomycin and netilmicin. Meanwhile, smear of centrifuged dialysate revealed acid fast bacilli on two occasions. We, then, started anti-TB therapy with oral isoniazid (INAH), rifampin and ethambutal. The symptoms subsided within three days. In the first week, the patient lost her peritoneal ultrafiltration and needed daytime automatic peritoneal dialysis. At the last follow-up examination, 12 months after treatment, she remained well on standard CAPD.

    Full Text Available Background: the increasing incidence of oral cancer is a global health problem; consequently, it is important to continue training professionals in primary care. Objective: to design a training proposal on oral cancer for professionals working in primary care. Methods: a mixed-method study involving 35 family physicians serving in the health area No.2 of Cienfuegos municipality was conducted from June 2011 to May 2012. A set of questionnaires were administered to family physicians, patients operated on during the study period, community members, and specialists responsible for the validation of the course. The variables analyzed included degree of specialization, time working in primary care, and knowledge about the oral cancer screening program and its application. Results: the knowledge about the program for early detection of oral cancer is not enough to meet the demands of the National Health System. A training course was designed and subsequently validated by the specialists, who claimed that it contributes to solving this problem, and facilitates the work of professionals in primary care. Conclusion: the proposal was regarded as new and relevant by the specialists. It can be used as a methodological tool for professional training in primary care.

  1. Lumbar peritoneal shunt

    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.

    The swan neck presternal catheter is composed of 2 flexible (silicon rubber) tubes joined by a titanium connector at the time of implantation. The exit site is located in the parasternal area. The catheter located on the chest was designed to reduce the incidence of exit site infections compared to peritoneal dialysis catheters with abdominal exits. From August 1991 to September 30, 2001, 974 swan neck presternal catheters were implanted worldwide. At the university of Missouri, 150 of these catheters were implanted and followed for over 130 patient years. Presternal catheters tended to perform better than swan neck abdominal catheters regarding exit and tunnel infections, even though they were implanted in several patients in whom regular catheters with the exit on the abdomen would be difficult or impossible to implant. Two-year survival probability of presternal catheters was 0.95. Recurrent/refractory peritonitis was the only reason for catheter failure. The catheter is particularly useful in obese patients (body mass index >35), patients with ostomies, children with diapers and fecal incontinence, and patients who want to take baths without the risk of exit contamination. Many patients prefer presternal catheter because of better body image. Disadvantages of the presternal catheter are minimal. Compared with abdominal catheters, dialysis-solution flow is slightly slower because of the increased catheter length; however, slower flow is insignificant clinically. There is a possibility of catheter disconnection in the tunnel, but this complication is extremely rare in adults and easily corrected. Finally, the implantation technique is more challenging compared with that of single-piece, abdominal catheters. PMID:12085389

    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.

    Full Text Available Encapsulating peritoneal sclerosis (EPS is a serious and often fatal complication of long-term peritoneal dialysis (PD with severe malnutrition and poor prognosis. It causes progressive obstruction and encapsulation of the bowel loops. As EPS becomes more prevalent with longer duration of PD, large multicenter prospective studies are needed to establish its incidence and identify risk factors, therapeutic approach, and prognosis.

    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.

    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.

    Full Text Available 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 tumour 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.

    Dong Wook Shin

    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.

    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.

    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

    腹膜肿瘤播散是进展期胃癌转移或胃癌根治术后复发最常见的类型,患者一旦出现腹膜转移复发的临床症状,其中位数生存期仅约4~6个月,预后极差。既往,一些辅助性化疗方案虽能改善患者的预后,但由于“血浆-腹膜屏障”作用,全身性化疗对于腹膜转移复发收效甚微。有鉴于此,近年来临床上应用全身性与腹腔内联合新辅助化疗﹙NIPS)治疗胃癌腹膜转移,取得了较好的效果。静脉内与腹腔内给以紫杉醇,并口服替吉奥﹙S-1)的联合化疗方案经过药动学与药效学研究,业已证实对患者有较好的耐受性,并在预防与治疗胃癌腹膜转移过程中取得较好的临床效果。本文中,作者对联合紫杉醇与S-1治疗胃癌腹膜转移的疗效作了较系统的介绍。%[Abstract ] Peritoneal dissemination is the most common metastasis form in patients with highly advanced gastric cancer ﹙AGC) or with recurrence after radical gastrectomy. The median survival time after manifestation of peritoneal carcinomatosis is about 4-6 months. Most systemic chemotherapeutic agents are not effective for peritoneal metastasis because of the blood-peritoneum barrier, although some adjuvant chemotherapy definitely improves overall survival. In this regard, neoadjuvant intraperitoneal-systemic chemotherapy ﹙NIPS) has been recently considered as an additional adjuvant therapy for AGC with peritoneal metastasis. Combined chemotherapy of intravenous and intraperitoneal paclitaxel with oral S-1 has been confirmed by pharmacokinetic and pharmacodynamic studies to be well tolerated and well effective in gastric cancer patients with peritoneal metastasis. In this article, authors make a comprehensive introduction to clinical efficacy by adopting paclitaxel and S-1 to gastric cancer patients with peritoneal metastasis.

  20. 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.

    Epidemiological studies in different areas in China have revealed several outstanding risk factors of PLC, i.e., HBV infection, pollution of drinking water, contamination of food by AFB1 and/or nitrosamines, and family predisposition. Accordingly, a program of HBV vaccination, improved supply of drinking water, better preservation and storage of food, and possibly chemoprevention for high-risk populations should be effective preventive measures. Studies have shown that frequent AFP screening in high-risk populations is highly recommended to detect early cases of PLC. According to research in Qidong, careful follow-up of the dynamic changes of AFP in individuals with persistent low levels of positive AFP is important for distinguishing other conditions from true PLC. Newer means for the localization of small-size PLC (under 5 cm), such as type B ultrasonography, nuclide scanning, computerized tomography, and hepatoangiography, represent remarkable progress in improving markedly the success of surgery and hence the survival rate of PLC patients. The advances in knowledge of PLC have been encouraging. Although much work remains to be done on the etiological agents and the mechanism of oncogenesis, it is time that larger scale control measures be put into effect in high-incidence areas to discover if one of the most common cancers in the world can be controlled. 62 references.

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

  4. [Guidelines for the early diagnosis of lung cancer for primary care physicians].

    Science.gov (United States)

    2016-01-01

    Lung cancer is a serious/medical and social problem. It belongs to the most common cancers. In the past decades, lung cancer has steadily held a leading place in the structure of cancer morbidity and mortality in our country and in the majority of European countries. Cigarette smoking remains to be the major if not only risk factor for lung cancer. Many attempts were previously made to set up systems for the early (timely) lung cancerdetection in risk groups through cytological and radiological examinations. Prophylactic fluorography and X-ray study have long been an important screening procedure in Russia and foreign countries. Recently this procedure has transformed into digital lung radiography. However, there have been no conclusive proofs for its efficiency in the early detection of lung cancer for a few decades. In the past decade, large-scale prospective randomized trials of low-dose computed tomography (CT) have been performed to screen lung cancer. These have shown that this technology can potentially reduce mortality from this disease. This encouraging result has caused a substantial change in the tactics of examining people at high risk for lung cancer. CT has fully replaced linear tomography and all others special X-ray procedures in the verified diagnosis of lung cancer. The indications for pre-examination CT have been considerably expanded in patients with X-ray detected pathology. The tactics for estimating the small lung tissue foci found at CT has been changed. Availability of CT, clear clinical indications for the study, and observance of the standard procedure have become important elements of the entire system for the early identification of lung cancer. These clinical recommendations largely deal just with organizational and methodological issues. The authors hope that the recommendations will serve as a guide for primary care physicians (therapists, pulmonologists,and radiologists) in the early diagnosis of lung cancer and in the optimization

    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.

  6. Asymptomatic Primary Fallopian Tube Cancer: An Unusual Cause of Axillary Lymphadenopathy

    Directory of Open Access Journals (Sweden)

    N. A. Healy

    2011-01-01

    Full Text Available Primary Fallopian tube malignancy is considered a rare disease and is often mistaken histologically and clinically for ovarian cancer. The etiology is poorly understood, and it typically presents at an advanced disease stage, as symptoms are often absent in the initial period. As a result, primary fallopian tube cancer is generally associated with a poor prognosis. We present the case of a 45-year-old female who presents with a 5-day history of left axillary swelling and a normal breast examination. Mammogram and biopsy of a lesion in the left breast revealed a fibroadenoma but no other abnormalities. Initial sampling of the axillary node was suspicious for a primary breast malignancy, but histology of the excised node refuted this. PET-CT showed an area of high uptake in the right pelvis, and a laparoscopy identified a tumor of the left fallopian tube which was subsequently excised and confirmed as a serous adenocarcinoma.

  7. 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)

    To capitalise on advances in breast cancer prevention, all women would need to have their breast cancer risk formally assessed. With ~85% of Australians attending primary care clinics at least once a year, primary care is an opportune location for formal breast cancer risk assessment and management. This study assessed the current practice and needs of primary care clinicians regarding assessment and management of breast cancer risk. Two facilitated focus group discussions were held with 17 primary care clinicians (12 GPs and 5 practice nurses (PNs)) as part of a larger needs assessment. Primary care clinicians viewed assessment and management of cardiovascular risk as an intrinsic, expected part of their role, often triggered by practice software prompts and facilitated by use of an online tool. Conversely, assessment of breast cancer risk was not routine and was generally patient- (not clinician-) initiated, and risk management (apart from routine screening) was considered outside the primary care domain. Clinicians suggested that routine assessment and management of breast cancer risk might be achieved if it were widely endorsed as within the remit of primary care and supported by an online risk-assessment and decision aid tool that was integrated into primary care software. This study identified several key issues that would need to be addressed to facilitate the transition to routine assessment and management of breast cancer risk in primary care, based largely on the model used for cardiovascular disease.

  10. Postoperative peritonitis without an underlying digestive fistula after complete cytoreductive surgery plus HIPEC

    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.

  11. 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.)

    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.

  13. 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.

The aims of this study were to elucidate the etiology, clinical presentation and outcomes associated with peritonitis in Lilongwe, Malawi. Methods All patients admitted to Kamuzu Central Hospital (KCH who underwent an operation for treatment of peritonitis during the calendar year 2008 were eligible. Peritonitis was defined as abdominal rigidity, rebound tenderness, and/or guarding in one or more abdominal quadrants. Subjects were identified from a review of the medical records for all patients admitted to the adult general surgical ward and the operative log book. Those who met the definition of peritonitis and underwent celiotomy were included. Results 190 subjects were identified. The most common etiologies were appendicitis (22%, intestinal volvulus (17%, perforated peptic ulcer (11% and small bowel perforation (11%. The overall mortality rate associated with peritonitis was 15%, with the highest mortality rates observed in solid organ rupture (35%, perforated peptic ulcer (33%, primary/idiopathic peritonitis (27%, tubo-ovarian abscess (20% and small bowel perforation (15%. Factors associated with death included abdominal rigidity, generalized (versus localized peritonitis, hypotension, tachycardia and anemia (p Conclusions There are several signs and laboratory findings predictive of poor outcome in Malawian patients with peritonitis.

    Zanon, Claudio

    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.

    Contralateral axillary lymph node metastases (CAMs) in breast cancer patients are uncommon. CAM can be found at the time of primary breast cancer diagnosis or following prior treatment of breast cancer as a recurrence. This distinction may have important implications for disease staging and treatment selection. We report the case of a premenopausal woman with synchronous CAM. Despite extensive multimodality treatment, a recurrence was found 27 months after primary surgery. We reviewed the lit...

  19. Impact of Primary Gleason Grade on Risk Stratification for Gleason Score 7 Prostate Cancers

    International Nuclear Information System (INIS)

    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.

    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.

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

    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.

Methods: We matched 30,220 men with PC to 151,100 men without PC (comparators on age (±2 years and PC diagnosis/index date. We focused on several methodological issues: 1 to address survival differences between the cohorts we compared rates with and without censoring comparators on the date their matched PC patient died or was censored; 2 to address diagnostic bias, we excluded men with a history of cancer from the comparator cohort; 3 to address prostate cancer immunity, we graphed the hazard of NPC in both cohorts, with and without prostate cancer as an outcome; 4 we used empirical Bayes methods to explore the effect of adjusting for multiple comparisons. Results: After 18 months of follow-up, cumulative person-time was lower in the PC than comparator cohort due to higher mortality among PC patients. Terminating person-time in comparators at the matched PC patient's death or loss to follow-up resulted in comparable person-time up to 30 months of follow-up and lower person-time among comparators thereafter. The hazard of NPC was lower among men with PC than comparators throughout follow-up. There was little difference in rates beyond the first four years of follow-up after removing PC as an outcome. Empirical Bayes adjustment for multiple comparisons had little effect on the

  8. 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.

  11. Water channels in peritoneal dialysis.

    Devuyst, Olivier

    2010-01-01

    Peritoneal dialysis involves diffusive and convective transports and osmosis through the highly vascularized peritoneal membrane. Several lines of evidence have demonstrated that the water channel aquaporin-1 (AQP1) corresponds to the ultrasmall pore predicted by the modelization of peritoneal transport. Proof-of-principle studies have shown that up-regulation of the expression of AQP1 in peritoneal capillaries is reflected by increased water permeability and ultrafiltration, without affecting the osmotic gradient and the permeability for small solutes. Inversely, studies in Aqp1 mice have shown that haploinsufficiency in AQP1 is reflected by significant attenuation of water transport. Recent studies have identified lead compounds that could act as agonists of aquaporins, as well as putative binding sites and potential mechanisms of gating the water channel. By modulating water transport, these pharmacological agents could have clinically relevant effects in targeting specific tissues or disease states. These studies on the peritoneal membrane also provide an experimental framework to investigate the role of water channels in the endothelium and various cell types.

  12. 131I treatment for thyroid cancer and risk of developing primary hyperparathyroidism: a cohort study

    International Nuclear Information System (INIS)

    To evaluate the association between 131I therapy for thyroid cancer and risk of developing primary hyperparathyroidism. This was a nationwide population-based cohort study of patients with thyroid cancer diagnosed during the period 1997-2008. The data were obtained from the Taiwan National Health Insurance Research dataset. The cumulative 131I dose in each patient was calculated. Hazard ratios (HRs) were calculated using a proportional hazards model to estimate the effect of 131I therapy on the risk of developing primary hyperparathyroidism in the cohort. A total of 8,946 patients with thyroid cancer were eligible for the final analysis. Among these patients, 8 developed primary hyperparathyroidism during the follow-up period that represented 38,248 person-years giving an incidence rate of 20.9 per 105 person-years. 131I was used in the treatment of 6,153 patients (68.8 %) with a median cumulative dose of 3.7 GBq. The adjusted HRs were 0.21 (95% CI 0.02-1.86) and 0.46 (95% CI 0.10-2.10) for those receiving a cumulative 131I dose of 0.1-3.6 GBq and ≥3.7 GBq, respectively, compared to no therapy. The risk of developing primary hyperparathyroidism did not increase with increasing 131I dose (test for trend p = 0.51). No interaction was found between 131I dose and age (p = 0.94) or 131I dose and sex (p = 0.99). 131I treatment for thyroid cancer did not increase risk of primary hyperparathyroidism during a 10-year follow-up in this study population. Further research with a longer follow-up period is needed to assess late adverse effects beyond 10 years. (orig.)

    The mesothelin (MSLN) gene encodes a 71 kilodalton (kDa) precursor protein that is processed into megakaryocytic potentiating factor (MPF), a 31 kDa protein that is secreted from the cell, and mature mesothelin (mMSLN), a 40 kDa cell surface protein. The mMSLN binds to CA125, an interaction that has been implicated in the intra-cavitary spread of mesothelioma and ovarian cancer. To better define the role of MPF and mMSLN, growth of the lung cancer cell line A549 was evaluated in immuno-deficient mice with inactivation of the Msln gene. We observed that Msln-/- mice xenografted with intraperitoneal A549 tumors survive significantly long than tumor-bearing Msln+/+ mice. When tumor-bearing Msln-/- mice are supplemented with recombinant MPF (and to a lesser extent mMSLN), most of this survival advantage is lost. These studies demonstrate that MPF and mMSLN have an important role in the growth of lung cancer cells in vivo and raise the possibility that inactivation of MPF may be a useful treatment for lung and other MSLN expressing cancers.

    2013-01-01

    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...

    This study examined distress, coping, and group support among a sample of rural women who had been recently diagnosed with breast cancer. We recruited 100 women who had been diagnosed with primary breast cancer at one of two time points in their medical treatment: either within a window up to 3 months after their diagnosis of breast cancer, or within 6 months after completing medical treatment for breast cancer. Their mean age was 58.6 years (SD = 11.6), and 90% were of white/European American ethnicity. Women completed a battery of demographic and psychosocial measures prior to being randomized into a psychoeducational intervention study, and then again 3 months later at a follow-up assessment. The focus of this article is on the women's self-reported psychosocial status at baseline. Many of the women experienced considerable traumatic stress regarding their breast cancer. However, this distress was not reflected in a standard measure of mood disturbance that is frequently used in intervention research (the Profile of Mood States). The average woman considered her diagnosis of breast cancer to be among the four most stressful life events that she had ever experienced. Also, women on average reported a high level of helplessness/hopelessness in coping with their cancer. On average, women felt that they "often" (but not "very often") received instrumental assistance, emotional support, and informational support. Women varied considerably in which kind of social group provided them with the most support, with as many reporting that they found the greatest support in spiritual/church groups or within their family units as with breast or general cancer groups. These results suggest that among these rural women with breast cancer, distress with the diagnosis of breast cancer must be carefully assessed, as women who are highly distressed about their breast cancer may not report general mood disturbance. Furthermore, the kinds of groups that rural women with breast cancer

    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

  7. 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

    @@ Multiple primary malignancies in a single patient are relatively rare but have increase in frequency in recent decades. This may be a result of medical advancements in diagnostic and therapeutic strategies, a possible effect of new carcinogens in the industrial environment, and longer life span allowing another primary cancer to develop. Among those with multiple primary malignancies, double cancer is commonly seen, while triple cancers occur in 0.5% of patients, and quadruple or quintuple cancers occur in only less than 0.1% of the population.~1 This report describes a rare case of a patient with five metachronous primary malignancies. The time interval between each of the malignancies is more than 2 years. Literatures about at least four primary malignancies are also discussed.

  9. 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)

  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)

    2016-01-01

    Earlier detection and newer treatments now make breast cancer highly survivable, and breast cancer survivors are the largest female cancer survivor group in the United States. With earlier detection, more women are being diagnosed with early-stage breast cancer and need follow-up care. With the increasing number of breast cancer survivors, there is a projected shortage in the workforce of oncology specialists to care for these women. The American Society of Clinical Oncology recommends that breast cancer follow-up care can be provided by an oncologist or primary care provider, as long as the primary care provider has spoken to the oncologist about appropriate follow-up care. Several studies have shown that primary care providers and oncologists have comparable outcomes for follow-up care of women with early-stage breast cancer. The National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) are considered the gold standard for breast cancer treatment and follow-up. These guidelines are clear and straightforward. Using knowledge of the NCCN Guidelines, primary care providers can fill the gap for follow-up care of women with early-stage breast cancer.

    Brain metastases are a frequent complication of many systemic cancers and portend a poor prognosis. This retrospective analysis of health claims data compared survival, treatment and health care utilization and costs in patients with brain metastasis by primary tumor site. Adult commercial and Medicare Advantage enrollees newly diagnosed with brain metastasis in 01 Jan 2004 through 30 Apr 2010 were identified. Inclusion required at least 2 claims that identified the same primary cancer site prior to diagnosis of brain metastasis and no evidence of primary brain tumors. Health care utilization rates and costs were calculated at the patient level for each month of follow-up. Differences among primary cancer site cohorts were assessed by ANOVA (continuous variables), Chi square test (proportions) and the Poisson distribution (utilization rates). The primary cancer cohorts comprised 1,031 lung cancer, 93 melanoma and 395 female breast cancer patients. During the 6 months prior to brain metastasis diagnosis, 59 % of lung cancer patients had no evidence of lymph node involvement or other metastatic disease compared to 55 and 42 % of melanoma and breast cancer patients (P < 0.001). Survival after brain metastasis diagnosis was less than 3 months for 52, 43 and 39 % for lung cancer, breast cancer and melanoma, respectively (P < 0.001). Melanoma patients had the highest rate of inpatient stays and outpatient visits (P ≤ 0.003). Total monthly all-cause costs were: melanoma, $23,426; breast cancer $19,708; lung cancer, $17,007 (P = 0.003). Health care utilization and costs after brain metastasis diagnosis were substantial and differed by primary tumor site.

    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.

    A phase I-II study of isotopic immunoglobulin therapy was performed in 18 patients with primary liver cancer; 14 were evaluable for toxicity. The patients received a dose of 37-157 millicuries of 131I-labeled antibody. The dose-limiting factor appears to be hematologic toxicity, especially thrombocytopenia. An objective antitumor effect was seen in six of nine patients who were evaluable for response. Present results suggest that further clinical studies with isotopic immunoglobulin are indicated.

  11. 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

    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.

    Cancer-related and primary lymphedema (LE) are associated with the production of adipose tissue (AT). Nothing is known, however, about the lipid-based molecules that comprise LE AT. We therefore analyzed lipid molecules in lipoaspirates and serum obtained from LE patients, and compared them to lipoaspirates from cosmetic surgery patients and healthy control cohort serum. LE patient serum analysis demonstrated that triglycerides, HDL- and LDL-cholesterol and lipid transport molecules remained ...

    Background: Vascular endothelial growth factor A (VEGFA) is essential in tumour angiogenesis, and polymorphisms in the VEGFA gene have been associated with breast cancer prognosis. The human epidermal growth factor receptor 2 (HER2) is overexpressed in breast tumours and is also associated...... with angiogenesis. We investigated the possible prognostic impact of VEGFA single nucleotide polymorphisms (SNPs) in patients with HER2-positive primary breast cancer. Patients and Methods: DNA was isolated from venous blood samples from 116 HER2-positive patients and genotyped for VEGFA -2578C>A, -1498T>C, -1154G...... multivariate analysis, only the -634CC genotype remained an independent prognostic factor (p=0.008). Conclusion: The VEGFA -634CC genotype was found to be associated with an inferior prognosis for patients with HER2-positive breast cancer....

  15. Evaluation of pN factors in patients with primary lung cancer by using perfusion, inhalation and ventilation studies

    International Nuclear Information System (INIS)

    The interpretation of scintigraphic patterns and the role of pathophysiological mechanisms in patients with primary lung cancer were investigated. 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)

    BACKGROUND: Research has revealed a shift towards Th2 in many types of malignant tumor, but the state of Th1/Th2 is not clear in patients with primary hepatic cancer (PHC). This study was designed to determine the expression of Th1-versus Th2-type cytokines in primary hepatic cancer and the adjacent liver tissue in order to provide evidence for treatment of the Th1/Th2 shift. METHODS:Samples were collected from 11 patients with PHC. The gene expression of Th1/Th2 cytokines was detected by reverse transcriptase polymerase chain reaction (RT-PCR) using IFN-γ and IL-2 as Th1-type cytokine genes, and IL-4 and IL-10 as Th2-type cytokine genes. RESULTS: Th1-type cytokines were expressed in 7/11 PHCs and 9/11 adjacent liver tissues, while Th0 type cytokines occurred in 4/11 PHCs and 2/11 adjacent liver tissues. CONCLUSION: Th1-type cytokines are expressed predominantly in primary hepatic cancer and the adjacent liver tissue.

    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.

    Between December 1973 and August 1987, 21 patients with primary liver cancer and 41 patients with metastatic liver cancer were treated with external irradiation, intra-arterial infusion chemotherapy and/or trans-arterial embolization (TAE) at the National Medical Center Hospital, the National South Kyushu Central Hospital and the National Kure Hospital. They were all inoperable cases. We diagnosed the tumor site and the involved area with many imagings and we decided the target volume. For primary liver cancer, the average survival period was 10.9 months, the 1-year survival rate was 28.6%, the 2-year survival rate was 14.3%, and the 3-year survival rate was 4.7%. Using multivariate analysis, stage, cancer reduction rate, Child classifiction and field size were valuable factors of the prognosis in the arterial infusion group. In the TAE group, cancer reduction rate was the most valuable factor. For metastatic liver cancer, the average survival period was 8.0 months, the 1-year survival rate was 19.5%, and the 5-year survival rate was 2.4%. Using multivariate analysis, pre-treatment K.P.S, distant metastasis, H, Child classification were valuable factors and pre-treatment K.P.S was most valuable factor. Although the indication of hepatic irradiation was generally thought to limit those cases which were Child A or B, H1 or H2 and the cases which have no distant metastasis, the cases which have their main portal tumor thrombus were also the indication of this therapy.

    Full Text Available Background: Breast (and cervical cancer affects a growing proportion of women in South Africa. Although treatable, where health literacy is low, women typically seek medical attention only when their condition is at an advanced stage and difficult to contain.Objectives: To understand the sociodemographic characteristics of women who present with advanced breast cancer in order to intervene proactively in primary care.Method: A retrospective analysis of women with advanced breast cancer (Stage IIb and higher at a Level 2 regional hospital in South Africa (2007–2010.Results: The average age amongst the 103 women enrolled in this study was 59. One-third of the women had secondary education, 35% were unemployed and two-thirds were notmarried. Nearly 11% (n = 11 of the women had previously had cancer. Lumps (n = 87 werethe most common reason for seeking healthcare and were, together with axillary lymphnode abnormalities (84.5% and 19.4% respectively, the most common clinical symptoms. Symptoms were noticed by 52% (n = 54 of the women more than six months prior to their first consultation. A personal history of cancer increased threefold the odds of presenting within three months. Middle-aged women were twice as likely as those < 45 and > 65 to report within three to six months. Secondary education increased the odds of presenting within three to six months by 56%. Employment and marital status were not significant.Conclusion: The women most at risk for delayed detection and treatment were those without a history of breast cancer, aged < 45 and > 65, with low education. They can best be reached through low-cost community orientated primary care that proactively provides health education and promotes self- and clinical examination at the individual, family, clinic and general practitioner level.

    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

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

    Questions have been raised about the safety of diagnostic hysteroscopy preceding surgical treatment of endometrial carcinoma. Several studies showed that the risk of a positive cytology among patients presenting endometrial adenocarcinoma was increased after diagnostic hysteroscopy, suggesting a peritoneal dissemination of tumor cells due to the exploration. We studied this hypothesis on the basis of a systematic review of the scientific data. Five studies fulfilling inclusion criteria have been selected and have been introduced into a fixed model of meta-analysis. On a total of 756 studied patients, 79 presented a positive peritoneal cytology. The diagnostic hysteroscopy did not increase significantly the risk of abdominal dissemination of tumor cells, the peritoneal cytology being positive among 38 patients in the group having undergone this intervention vs 41 patients in the control group (OR = 1,64; 95% CI: 0,96-2,80). In conclusion, no formal evidence is currently available concerning the role of diagnostic hysteroscopy on the frequency of peritoneal dissemination of tumor cells, or on the vital prognosis of the patients presenting with endometrial carcinoma. From the data available, there is not any reason to avoid diagnostic hysteroscopy in the initial workup of endometrial cancer. PMID:15894211

  4. Automated Peritoneal Dialysis Is Associated with Better Survival Rates Compared to Continuous Ambulatory Peritoneal Dialysis: A Propensity Score Matching Analysis.

    Full Text Available The impact of peritoneal dialysis modality on patient survival and peritonitis rates is not fully understood, and no large-scale randomized clinical trial (RCT is available. In the absence of a RCT, the use of an advanced matching procedure to reduce selection bias in large cohort studies may be the best approach. The aim of this study is to compare automated peritoneal dialysis (APD and continuous ambulatory peritoneal dialysis (CAPD according to peritonitis risk, technique failure and patient survival in a large nation-wide PD cohort.This is a prospective cohort study that included all incident PD patients with at least 90 days of PD recruited in the BRAZPD study. All patients who were treated exclusively with either APD or CAPD were matched for 15 different covariates using a propensity score calculated with the nearest neighbor method. Clinical outcomes analyzed were overall mortality, technique failure and time to first peritonitis. For all analysis we also adjusted the curves for the presence of competing risks with the Fine and Gray analysis.After the matching procedure, 2,890 patients were included in the analysis (1,445 in each group. Baseline characteristics were similar for all covariates including: age, diabetes, BMI, Center-experience, coronary artery disease, cancer, literacy, hypertension, race, previous HD, gender, pre-dialysis care, family income, peripheral artery disease and year of starting PD. Mortality rate was higher in CAPD patients (SHR1.44 CI95%1.21-1.71 compared to APD, but no difference was observed for technique failure (SHR0.83 CI95%0.69-1.02 nor for time till the first peritonitis episode (SHR0.96 CI95%0.93-1.11.In the first large PD cohort study with groups balanced for several covariates using propensity score matching, PD modality was not associated with differences in neither time to first peritonitis nor in technique failure. Nevertheless, patient survival was significantly better in APD patients.

    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.

    Full Text Available Abstract Background Tumor cell lines are commonly used as experimental tools in cancer research, but their relevance for the in vivo situation is debated. In a series of 11 microsatellite stable (MSS and 9 microsatellite unstable (MSI colon cancer cell lines and primary colon carcinomas (25 MSS and 28 MSI with known ploidy stem line and APC, KRAS, and TP53 mutation status, we analyzed the promoter methylation of the following genes: hMLH1, MGMT, p16INK4a (CDKN2A α-transcript, p14ARF (CDKN2A β-transcript, APC, and E-cadherin (CDH1. We compared the DNA methylation profiles of the cell lines with those of the primary tumors. Finally, we examined if the epigenetic changes were associated with known genetic markers and/or clinicopathological variables. Results The cell lines and primary tumors generally showed similar overall distribution and frequencies of gene methylation. Among the cell lines, 15%, 50%, 75%, 65%, 20% and 15% showed promoter methylation for hMLH1, MGMT, p16INK4a, p14ARF, APC, and E-cadherin, respectively, whereas 21%, 40%, 32%, 38%, 32%, and 40% of the primary tumors were methylated for the same genes. hMLH1 and p14ARF were significantly more often methylated in MSI than in MSS primary tumors, whereas the remaining four genes showed similar methylation frequencies in the two groups. Methylation of p14ARF, which indirectly inactivates TP53, was seen more frequently in tumors with normal TP53 than in mutated samples, but the difference was not statistically significant. Methylation of p14ARF and p16INK4a was often present in the same primary tumors, but association to diploidy, MSI, right-sided location and female gender was only significant for p14ARF. E-cadherin was methylated in 14/34 tumors with altered APC further stimulating WNT signaling. Conclusions The present study shows that colon cancer cell lines are in general relevant in vitro models, comparable with the in vivo situation, as the cell lines display many of the same

    Sclerosing peritonitis is a dramatic complication of continuous ambulatory peritoneal dialysis and chronic peritoneal inflammation. Both visceral and parietal surfaces of the peritoneal cavity are involved. A thickened peritoneum encloses the small intestine in a "cocoon" formation which often leads to intestinal occlusion. CT scan may help obtaining an early diagnosis but diagnosis is often established with some delay or even at the time of laparotomy. Our report describes three cases of this uncommon peritoneal fibrosis syndrome which caused intestinal obstruction requiring surgical intervention. PMID:14524162

    Full Text Available Second primary malignancy (SPM is the major long-term cause of patient mortality with head and neck squamous cell carcinoma (HNSCC. As the incidence of high-risk human papillomavirus (HPV-related HNSCC is increasing globally, we analyzed the patterns of SPM occurrence, the effect of the index tumor site along with attributes to HPV, and the effect of SPM on survival in South Korean patients with head and neck cancer (HNC. Data were retrieved from the Korea Central Cancer Registry, a nationwide population-based cancer registry, from 1993 to 2010. Standardized incidence ratios were analyzed and compared between index tumor sites, particularly oropharyngeal vs. non-oropharyngeal sites. After adjustment for competing risks, 3- and 5-year SPM rates were calculated using the cumulative incidence function. The effects of SPM occurrence on overall survival (OS were then analyzed. SPM rates were significantly lower for HPV-attributable oropharyngeal sites than for non-oropharyngeal sites, such as the larynx and hypopharynx (p<0.001. SPM rates were also lower for oral cavity first primary sites than for non-oropharyngeal first primary sites (p<0.001. SPMs typically occurred in the esophagus, lungs and the head and neck. Uterine cervical cancers occurred significantly more frequently after index oropharyngeal cancer in women. The 5-year and 10-year OS rates were 57.8 and 45.7% in all HNC patients, respectively. The OS after SPM occurrence was poor (5-year, 31.8%; 10-year, 20.8% compared to after index HNC occurrence (5-year, 68.4%; 10-year, 41.2%. SPM occurrence in the esophagus and lung/bronchus showed a worse OS than SPM localized to the head and neck. South Korean HNC patient, the first primary cancer site affected SPM risk and distribution. The 5- and 10-year OS rates deteriorated after SPM occurrence, particularly in the esophagus and lungs.

    Lung cancer is a serious/medical and social problem. It belongs to the most common cancers. In the past decades, lung cancer has steadily held a leading place in the structure of cancer morbidity and mortality in our country and in the majority of European countries. Cigarette smoking remains to be the major if not only risk factor for lung cancer. Many attempts were previously made to set up systems for the early (timely) lung cancerdetection in risk groups through cytological and radiological examinations. Prophylactic fluorography and X-ray study have long been an important screening procedure in Russia and foreign countries. Recently this procedure has transformed into digital lung radiography. However, there have been no conclusive proofs for its efficiency in the early detection of lung cancer for a few decades. In the past decade, large-scale prospective randomized trials of low-dose computed tomography (CT) have been performed to screen lung cancer. These have shown that this technology can potentially reduce mortality from this disease. This encouraging result has caused a substantial change in the tactics of examining people at high risk for lung cancer. CT has fully replaced linear tomography and all others special X-ray procedures in the verified diagnosis of lung cancer. The indications for pre-examination CT have been considerably expanded in patients with X-ray detected pathology. The tactics for estimating the small lung tissue foci found at CT has been changed. Availability of CT, clear clinical indications for the study, and observance of the standard procedure have become important elements of the entire system for the early identification of lung cancer. These clinical recommendations largely deal just with organizational and methodological issues. The authors hope that the recommendations will serve as a guide for primary care physicians (therapists, pulmonologists,and radiologists) in the early diagnosis of lung cancer and in the optimization

    The present financial crisis will affect primary cancer prevention through several avenues: personal lifestyle choices, exposure to environmental risk factors, decisions made in the private sector and public policy on cancer prevention. Whilst it is clearly problematic to reach solid conclusions on a direct connection between economic crises and cancer mortality, we can identify trends that provide guidance for further action. For some lifestyle choices such as smoking or diet, we argue that public policy may channel existing tendencies during times of crisis for clear added value. In other areas, including research and health system investments, we will make the case that the resources not used now for cancer prevention efforts will lead to increased costs (both financial and human) down the road. Policy makers face a clear choice: they can follow a cost contention strategy, which may reduce expenditure in the short-term only to increase it in the long-term, or they can use the financial crisis as an opportunity to make difficult choices in terms of health service rationalisation, whilst at the same time strengthening evidence-based prevention policies. In short, we argue that despite the scarcity of funds and the governmental priorities on economic recovery, cancer prevention is more relevant now than ever.

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

    Melanoma-associated antigen-A (MAGE-A) and New York esophageal squamous cell cancer-1 (NY-ESO-1) are 2 cancer testis antigens (CTA) demonstrating potential for use in targeted immunotherapy. Clinical trials in melanoma and synovial sarcomas targeting these antigens in immune-based therapies have demonstrated durable tumor regression. Although protein expression of NY-ESO-1 has been assessed in a variety of cancer types, the expression of MAGE-A has not been studied in depth. In this study we analyzed MAGE-A and NY-ESO-1 expression in 314 melanoma specimens from 301 melanoma patients, 38 patients with squamous cell cancers and 111 patients with adenocarcinomas. Our results demonstrated higher expression of MAGE-A compared with NY-ESO-1 in melanomas (32% vs. 13%) and squamous cell carcinomas (45% vs. 7.9%), and higher expression of both CTAs in metastatic versus primary tumors. CTA expression in adenocarcinomas was low (MAGE-A: 10%, NY-ESO-1: 0.9%). In addition, we looked at concordance of expression among metastatic melanoma lesions within the same patient and found concordant expression in 38 of 47 patients for MAGE-A and 43 of 47 patients for NY-ESO-1. Our study demonstrated that the MAGE-A family may be of greater utility than NY-ESO-1 for targeted immunotherapy in a variety of cancer histologies, in particular metastatic melanomas and squamous cell carcinomas.

    Full Text Available Introduction. A bleeding syndrome in the setting of primary hyperfibrinolysis in a prostate cancer patient is only 0.40– 1.65% of cases. The laboratory diagnosis of primary hyperfibrinolysis is based on the increase of biomarkers like D-dimer, fibrinogen split products, plasminogen, and euglobulin lysis test. These tests are not specific for primary hyperfibrinolysis. We reported a rare case of hemorrhagic syndrome caused by primary hyperfibrinolysis as the first clinical symptom of metastatic prostate cancer. Case report. A 64-year-old male was admitted to our hospital with large hematomas in the right pectoral and axillary areas (20 x 7 cm, right hemiabdomen (30 x 30 cm and the left lumbal area, (25 x 5 cm. The patient had no subjective symptoms nor used any medication. Initial coagulation testing, prothrombin time (PT, and activated partial thromboplastin time (APTT were within the normal range, while fibrinogen level was extremely low (1.068 g/L (normal range 2.0–5.0 and the D-dimer assay result was high 1.122 mg/L (normal range < 0.23. The results obtained by rotation thrombelastometry pointed to primary fibrinolysis. Further clinical and laboratory examination indicated progressive malignant prostate disease. First line treatment for the patient was a combined administration of tranexamic acid (3 x 500 mg iv and transfusion of ten units of cryoprecipitate (400 mL. Next day, fibrinolytic function measurements by rotation thrombelastometry were within the normal ranges. Fibrinogen level was normalized within two days (2.4 g/L. There were no newly developed hematomas. Conclusion. This case report shows primary hyperfibrinolysis with bleeding symptoms, which is an uncommon paraneoplastic phenomenon within expanded prostate malignancy. Rotation thrombelastometry in this severe complication helped to achieve the prompt and proper diagnosis and treatment.

    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

    We analyzed the interactions between human primary cells from pancreatic ductal adenocarcinoma (PDAC) and polymeric scaffolds to develop 3D cancer models useful for mimicking the biology of this tumor. Three scaffold types based on two biocompatible polymeric formulations, such as poly(vinyl alcohol)/gelatin (PVA/G) mixture and poly(ethylene oxide terephthalate)/poly(butylene terephthalate) (PEOT/PBT) copolymer, were obtained via different techniques, namely, emulsion and freeze-drying, compression molding followed by salt leaching, and electrospinning. In this way, primary PDAC cells interfaced with different pore topographies, such as sponge-like pores of different shape and size or nanofiber interspaces. The aim of this study was to investigate the influence played by the scaffold architecture over cancerous cell growth and function. In all scaffolds, primary PDAC cells showed good viability and synthesized tumor-specific metalloproteinases (MMPs) such as MMP-2, and MMP-9. However, only sponge-like pores, obtained via emulsion-based and salt leaching-based techniques allowed for an organized cellular aggregation very similar to the native PDAC morphological structure. Differently, these cell clusters were not observed on PEOT/PBT electrospun scaffolds. MMP-2 and MMP-9, as active enzymes, resulted to be increased in PVA/G and PEOT/PBT sponges, respectively. These findings suggested that spongy scaffolds supported the generation of pancreatic tumor models with enhanced aggressiveness. In conclusion, primary PDAC cells showed diverse behaviors while interacting with different scaffold types that can be potentially exploited to create stage-specific pancreatic cancer models likely to provide new knowledge on the modulation and drug susceptibility of MMPs.
