Abstract: Background: The intention of cancer chemotherapy is to control the growth of cancer cells using chemical agents. However, the occurrence of second malignancies has raised concerns, leading to re-evaluation of the current strategy in use for chemotherapeutic agents. Although the mechanisms involved in second malignancy remain ambiguous, therapeutic-agent-induced non-DNA targeted effects like bystander response and genomic instability cannot be eliminated completely. Hence, Bleomycin (BLM) and Neocarzinostatin (NCS), chemotherapeutic drugs with a mode of action similar to ionizing radiation, were used to study the mechanism of bystander response in human cancer cells (A549, CCRF-CEM and HL-60) by employing co-culture methodology. Methods: Bystander effect was quantified using micronucleus (MN) assay and in-situ immunofluorescence(γH2AX assay).The role of reactive oxygen species (ROS) and nitric oxide (NO) in mediating the bystander response was explored by pre-treating bystander cells with dimethylsulphoxide (DMSO) and C-PTIO respectively. Results: Bystander response was observed only in CCRF-CEM and A549 cells (P < 0.001). A significant decrease in this response was observed with ROS scavenger, DMSO. Conclusions: This significant attenuation in the bystander response on treatment with DMSO, suggests that ROS has a more significant role in mediating the bystander response.Since the possibility of the ROS and NO in mediating these bystander effect was confirmed, mechanistic control of these signaling molecules could either reduce radiation damage and potential carcinogenicity of normal tissues (by reducing bystander signaling) or maximize cell sterilization during chemotherapy (by amplifying bystander responses in tumors).

Abstract: Metastatic carcinoma to the testis, excluding lymphoma and leukemia, is an extremely rare condition. The most frequent primary site is prostate cancer. These lesions present clinically either as the first sign of malignancy or more commonly as a complication during the course of known disease. We present the first case of a squamous cell carcinoma of the lung diagnosed with a testicular mass, which is very rarely seen in literature, to our knowledge. doi: http://dx.doi.org/10.4021/wjon568w

Abstract: Background: Nodal metastasis from cutaneous SCC carries a high morbidity and mortality. Limited direct evidence is available as to the impact of radiotherapy on the outcome of patients with metastatic axillary SCC. The purpose of this study was to report on the outcomes of patients with metastatic cutaneous SCC to the axilla treated with radiotherapy. Methods: A retrospective review of patients treated with radiotherapy between 1993 and 2010 for metastatic cutaneous SCC to the axilla was undertaken at St George Hospital, Sydney. Results: Radiotherapy was administered to 36 patients, 30 with curative intent (4 definitive, 26 adjuvant) and 6 with palliative intent, 27/36 (75%) were male, 22/36 (61%) had a previous diagnosis of cutaneous SCC, and 1/36 (3%) was immunosuppressed. Mean age was 74.6 years. Mean radiotherapy dose (BEDGy10) was 61Gy 10 (range 39-85 Gy 10 ), 20/36 (56%) patients experienced recurrence, including 16 local failures and 4 isolated distant failures. Median survival for the curative and palliative groups was 3 years and 1 month, respectively. Relapse free survival (n = 36) at 2 and 5 years was 46% and 35%, respectively (curative 52% and 39%). Only 1 failure achieved complete salvage. Conclusion: Despite current best practice (surgery and radiotherapy), the predominant pattern of failure in these patients with metastatic axillary cSCC was locoregional. The difficulty in successfully salvaging patients after locoregional nodal relapse suggests a need for treatment intensification . doi: http://dx.doi.org/10.4021/wjon503w

Abstract: It is rare for prostate carcinoma to metastasize to the central nervous system. It often represents a terminal event with death in one year frequently due to the advanced systemic disease. Starting by a case report, we also reviewed the relevant literature to focus on this uncommon entity from epidemiology to clinical manifestation and therapeutic strategies. In this article, a case of multiple brain prostate metastasis is reported and a review of relevant literature is also discussed. Treatments available for intracranial metastasis include neurosurgery, external beam radiation and hormonal manipulation. Surgery associated with whole brain radiotherapy seems to be effective in the control of brain lesions both relieving neurological symptoms and prolonging survival, even if prognosis remains dismal. From this case, we concluded that brain metastasis from prostate carcinoma is a rare, terminal event with death in one year frequently due to the advanced systemic disease. A better understanding of the biology of prostate carcinoma will help clarify the basis for its metastasis to the brain.

Abstract: Herpes zoster, also known as shingles, occurs upon reactivation of a primary infection with varicella zoster virus (VZV). Risk factors for reactivation include stress, older age, and immunosuppression, all of which are associated with a decrease in host immunity. Common complications of herpes zoster include scarring and post-herpetic neuralgia (PHN). Cutaneous lesions such as granuloma annulare, lymphomas, and sarcoid granulomas have also been reported to potentially arise at the site of herpes zoster. Here, we report a case that to our knowledge is the first presentation of diffuse large B-cell lymphoma with its only cutaneous manifestation arising in a herpes zoster scar. Punch biopsy was performed on a nodule appearing in a dermatomal distribution within the herpes zoster scar. Histopathology revealed an atypical lymphoid infiltrate in the dermis that was determined to be CD20 positive B-cells. Immunostains for CD20, CD79a, and PAX-5 showed strong positive staining of the atypical cells, confirming B-cell origin and resulting in the diagnosis of lymphoma, large B-cell type. This case highlights the importance of raising clinical suspicion for a malignant process in patients who present with a changing or unresolving skin manifestation after infection with varicella zoster virus.

Abstract: Background: Soluble IL-2 receptor (sIL-2R) is the circulating form of a membrane receptor localized on lymphoid and some tumor cells; its biological function is not completely understood. Methods: Serum levels of sIL-2R in blood samples taken from 51 cancer patients (21 gastric and 30 colorectal) and 18 healthy volunteers were measured and found to be significantly higher in the patients. Results: Concentrations were significantly inversely correlated to nutritional parameters, including total protein and short turnover proteins such as prealbumin, retinol binding protein and transferrin, as well as to the stimulation index, which is a classical parameter of cell-mediated immunity. Concentrations were significantly positively correlated to neutrophil count and inversely to lymphocyte count. Significantly elevated levels of circulating myeloid-derived suppressor cells (MDSCs) were found in patients; this was significantly correlated to sIL-2R levels. Conclusions: Increased production of sIL-2R correlated with systemic inflammation, nutritional impairment and inhibition of cell-mediated immunity, and thus may be involved in immunological mechanisms inducing cancer cachexia. The same factors also appear to relate closely to induction of MDSCs. doi: http://dx.doi.org/10.4021/wjon548e

Abstract: Background: There is lack of consensus on the incidence of appendiceal carcinoids in recent times. The influence of number of appendicectomies performed has been postulated to play a role in this. To determine the incidence and clinico-pathological profile of appendiceal carcinoids in a cohort of patients undergoing emergency appendicectomies for clinically suspected acute appendicitis, and examine the influence of the trend (if any) of the number of appendicectomies performed on the overall incidence of appendiceal carcinoids. Methods: A retrospective analysis of patients diagnosed with appendiceal carcinoids following presentation with acute appendicitis to the Modbury hospital, South Australia from March 2007 to April 2011. The patient cohort was divided into Group 1 (March 2007 - March 2009) and group 2 (April 2009 - April 2011) to study the influence of time trends on incidence of appendiceal carcinoids. Statistical analyses were performed using the Statistical Product and Service Solutions, SPSS 14.0 for Windows. Results: Of 506 patients who underwent emergency appendicectomy for acute appendicitis, 8 patients (1.6%) were found to have appendiceal carcinoids. The median age was 23 years with 7 patients being female. There was no difference in the incidence of appendiceal carcinoids over the two time periods (P < 0.12) . Conclusions: Appendiceal carcinoids were found in 1.6% of patients undergoing emergency appendicectomy for acute appendicitis. These tumors are found more commonly in young females with a predilection for the tip of the appendix. The perceived increased incidence appendiceal carcinoids appear to be unrelated to the increase in the number of appendicectomies being performed. doi: http://dx.doi.org/10.4021/wjon400w

Abstract: Multiple myeloma - a neoplastic proliferation of plasma cell is the second most common blood cancer. Multiple myeloma is characterized by neoplastic proliferation of the plasma cells. These cells infiltrate variety of organs. Infiltration by immature neoplastic cells and overproduction of monoclonal immunoglobulin chain is responsible for clinical manifestations of multiple myeloma. The most common clinical presentation of multiple myeloma is an asymptomatic person having anemia and elevated globulin in laboratory testing. Multiple myeloma is diagnosed by triad of > 10% marrow infiltration by plasma cells, serum/urine monoclonal protein and end organ damages. One of the common end organ damage is lytic bone lesions resulting from imbalance between osteolytic and osteoblastic activities. Lymphadenopathy and osteoblastic lesions are rare presentations of multiple myeloma - lymphadenopathy in 1% of cases with IgA subtype and osteoblastic lesions in IgE myeloma and lambda light chains. Osteoblastic multiple myeloma is a distinct entity from POEMS syndrome. IgG myeloma with kappa chain predominance is not described yet with osteoblastic lesions and lymphadenopathy. We present a rare case of IgG myeloma with kappa chain predominance that had both lymphadenopathy and osteoblastic lesions.

Abstract: Background: The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is a quality of life (QOL) assessment tool that was originally developed for use in patients with primary brain tumors. However, the tool has also been used to assess QOL in patients with metastatic brain tumors. The purpose of this study is to compare the differences in QOL responses as assessed by the FACT-Br in patients with primary and metastatic brain neoplasms. Methods: A systematic literature search was conducted using the OvidSP platform in MEDLINE (1946 to July Week 2 2012) and EMBASE (1980 to 2012 Week 28). Articles in which the FACT-Br was used as a QOL assessment for patients with malignant brain tumors (both primary and metastatic) were included in the study. The weighted means of FACT-Br subscale and overall scores were calculated for the studies. To compare these scores, weighted analysis of variance was conducted and PROC GLM was performed for the data. A P-value of < 0.05 was considered statistically significant. Results: A total of 23 studies (four in brain metastases, 18 in primary brain tumors and 1 in a mixed sample) using the FACT-Br for assessment of QOL were identified. Social and functional well-being were significantly better in patients with primary brain tumors (weighted mean score of 22.2 vs. 10.7, P = 0.0026, 16.9 vs. 6.2, P = 0.0025, respectively). No other scale of the FACT-Br was significantly different between the two groups and the performance status of patients included in both groups was similar. Conclusion: Patients with primary brain cancer seemed to have better social and functional well-being scores than those with metastatic brain tumors. Other QOL domains were similar between these two groups. However, the heterogeneity in the included studies and the low sample size of included samples in patients with metastatic brain tumors could have confounded our findings. doi: http://dx.doi.org/10.4021/wjon585w

Abstract: Background: Serum carcinoembryonic antigen (CEA) levels are not universally measured in colorectal cancers. CEA levels have been reported to be usually normal at time of primary rectal cancer diagnosis but elevated in recurrent disease. The aims of the study were to (1) compare serum CEA levels performed at time of primary and recurrent colorectal tumour diagnosis; and (2) to determine serum CEA levels in rectal cancers at primary diagnosis to analyse potential factors influencing differing CEA levels. Methods: A retrospective analysis of patients treated for colorectal cancers at Modbury Hospital, South Australia was performed. Each admission was reviewed within the electronic database. Serum CEA levels and tumour-related factors were determined in patients who underwent curative surgery for their primary tumour and developed tumour recurrence / metastases within the study period. Results: 438 patients were treated for colorectal cancer in the study period. In patients who underwent curative surgery and developed a recurrence, serum CEA was elevated in 20% patients at primary diagnosis and in 46.6% patients at recurrence. Only 1 of 30 patients with rectal cancer had an elevated CEA at diagnosis of primary tumour. Tumour relationship to the peritoneal reflection did not appear to play a role. Conclusions: In rectal cancers, serum CEA levels are often normal at the time of initial diagnosis. However, this should not preclude its use in post-operative surveillance. Serum CEA levels noted in primary rectal cancer appear unrelated to the relationship of the tumour to the peritoneal reflection. Stroma-related factors could possibly be involved and merit further investigation. doi:10.4021/wjon479w

Abstract: Leptomeningeal carcinomatosis (LC) is a rare and devastating metastatic manifestation of both liquid and solid tumors consisting of dissemination of malignant cells with invasion into the meninges. Few options exist in most clinical situations, especially when LC is the presenting sign of occult malignancy. The prognosis is often poor with limited survival. Aims of palliation must be considered the primary goal for most patients. We report a case in which occult metastatic breast cancer presented with neurological symptoms from LC. We discuss diagnosing the primary malignancy when LC is the presenting manifestation as well as treatment, both palliative and cytoreductive. We also focus on those patients with breast cancer that are at highest risk of developing LC.

Abstract: Germ cell tumors (GCTs) occur generally in the testes or ovaries. Extra-gonadal location of GCTs is very rare .Extra-gonadal GCTs usually arise from midline structures, the commonest sites being the retroperitoneal and mediastinum. Gastrointestinal germ cell tumors are very uncommon. The etiology, prognosis and clinical course of gastrointestinal GCTs are not well understood yet. Weherein present two GCTs cases who referred with gastrointestinal bleeding and obstruction these tumors originated from retroperitoneal site. In the light of the literature, the clinical and pathological findings of the cases are presented. Prominent features of our cases were being located in the gastrointestinal system, being at young ages, presenting with gastrointestinal bleeding and good outcome.

Abstract: Literature on the outcome of pregnancy with first trimester exposure to Temozolomide is limited. We describe the case of a young woman with Glioblastoma Multiforme who was exposed to Temozolomide during her first trimester of pregnancy and subsequently delivered a healthy term newborn. At six months of age, the child remains healthy with no evidence of Temozolomide related effects.

Abstract: A 53-year-old smoker female presented to our hospital with abdominal pain secondary to acute pancreatitis. Severe hypercalcemia was felt to be the precipitating cause of pancreatitis. Her work up showed SCLC with bone marrow metastases as the only site of extra-thoracic metastases. We review the literature regarding hypercalcemia mechanisms in patients with SCLC.

Abstract: Background: We aimed to test the hypothesis that whether FDG-PET / CT which was ordered for various purposes can predict suspected or particularly unsuspected bone marrow metastasis (BMM) from the complete blood count and therefore can change the management of these patients. Methods: In this retrospective study, the study sample consisted of 68 subsequent patients presented to our institution ' s pathology department with bone marrow metastases of solid tumors. PET / CT was found to have been ordered in 10 out of 68 patients (6.8%) for various purposes. All patients gave informed consent about the PET / CT examinations and bone marrow biopsies. Result: FDG-PET / CT was ordered in 10 out of 68 solid tumor patients with pathologically proven BMM. Of these 10 patients, 3 were female and 7 were male; mean age was 54.7 years. While FDG PET / CT showed bone and BMM in 4 of 10 patients (40%), the rest of the patients had BMM without bone involvement. Five patients (50%) who had probable bone marrow involvement on their FDG PET / CT scans had unsuspected complete blood counts with regard to BMM. Conclusion: PET / CT has the ability to detect a substantial number of metabolically active tumor cells in the bone marrow in all of our patients which we proved by bone marrow biopsies. We think that this cohort of patients with solid tumors is hypothesis-generating with regard to detecting early bone marrow metastases by FDG PET / CT.

Abstract: Angiosarcoma arising in the pulmonary artery is extremely rare. We herein report a case of angiosarcoma arising in the pulmonary artery trunk of 71 year-old woman. This case was clinically diagnosed as pulmonary thromboembolism but angiosarcoma of the pulmonary artery should be considered as the differential diagnosis of unusual clinical manifestations of pulmonary thromboembolism because of the extremely poor prognosis of the lesion.

Abstract: Background: Hepatocellular carcinoma (HCC) is a primary malignant tumor of the liver that represents a serious public health problem all over the world, corresponding to the third cause of cancer death worldwide. The object was to present the clinical characteristics and follow-up of patients with HCC attended at the University Hospital of the Faculty of Medicine of Ribeirao Preto-USP (HCFMRP-USP), Ribeirao Preto, Sao Paulo, Brazil. Methods: Epidemiological and clinical data were revised from medical records. Results: A total of 130 patients participated in the study, 81.5% of them being males. Mean ( ± SD) age at the time of HCC diagnosis was 55.6 ± 11.2 years. Cirrhosis was present in 89.2% of cases, with 53.4% of the patients being Child-Pugh A; chronic hepatitis B or C without cirrhosis was detected in 3.2%, non-alcoholic steatohepatitis (NASH) in 3.8%, and a normal liver in 3.8%. Orthotopic liver transplantation was performed in 26.2% of the subjects, 16.9% of the patients were submitted to surgical resection, and 6.2% to percutaneous ethanol infusion (PEI). Transarterial embolization and transarterial chemoembolization were performed in 9.2% of the patients. Systemic chemotherapy was applied to 4.6% of cases and 24.6% of the patients received symptomatic treatment. Conclusion: Thus, in the present series cirrhosis was the main risk factor for HCC, with 53.4% of the patients being Child-Pugh A. Liver transplantation or surgical resection of the tumor, potentially curative techniques, were possible in only 43.1% of cases. doi: http://dx.doi.org/10.4021/wjon549w

Abstract: Palliative radiotherapy (RT) is prescribed to patients with bone metastases to alleviate symptoms and improve quality of life. The lack of consistent endpoints for such trials has made cross study comparison difficult and has led to contradictory conclusions. The International Bone Metastases Consensus Working Party was established to create a standard set of endpoints and recommendations for future clinical trials. Recommendations were included regarding eligibility criteria, pain assessments, follow-up assessments, timing, as well as radiation techniques. Suggestions were also made to facilitate the ease with which different studies could be compared as well as to encourage widespread consistency in certain aspects of trial design. Investigators conducting clinical trials in bone metastases should continue to adopt these recommendations to ensure consistent guidelines based on the most recent literature.

Abstract: Background: Although anticoagulation therapy is commonly used in the prostate cancer population, there are only a few studies about the correlation between radiation proctitis and anticoagulation therapy. The purpose of the present study was to determine whether low-dose aspirin increases the severity of acute radiation proctitis in an experimental animal model. Method s: Wistar rats were used in the present study. The rats were administered either aspirin at doses of 5, 10, and 20 mg/kg, or saline, daily before and after irradiation. The rats were irradiated to the rectum as a single fraction of 25 Gy. The rectal mucosal changes of each rat were evaluated macroscopically and pathologically on the tenth day following irradiation. The findings of proctitis were graded from 0 to 4, and then were compared with regard to the status. Results: No apparent correlations were observed between the administration of aspirin and the severity of radiation proctitis in the macroscopic findings and in the morphological mucosal damage in the pathological examination. The proportion of rats with a severe degree of mucosal inflammation was 90.0%, 100.0%, 16.7% and 100.0% at 5 mg/kg, 10 mg/kg, and 20 mg/kg of aspirin, or saline, respectively. The rats receiving aspirin at the dose of 20 mg/kg showed significantly milder inflammation than the other groups (P < 0.05). Conclusions: In the present study, low-dose aspirin did not increase the severity of acute radiation proctitis. In addition, aspirin might decrease the severity of radiation-induced mucosal inflammation in the rectum. doi: http://dx.doi.org/10.4021/wjon559w

Abstract: Background : Cancer diagnosis coupled with emotional impact converge to create one of the most difficult physical and emotional periods of life. Cancer treatment causes plethora of short and long term complications which can be so debilitating that patient may interrupt treatment. Pretreatment oral assessment and supportive oral care during and after cancer therapy can increase quality of life and supportive care costs. Methods: Study was conducted on 189 patients (86: head and neck cancer cases, group I and 103: other than head and neck cancer cases, group II) receiving cancer therapy. Patients were subjected to clinical assessment and findings were recorded in specially designed proforma and complete oral (objective and subjective) and constitutional findings were recorded. Results: Among the patients undergoing chemotherapy in both groups, p revalence of oral findings was found to be highest with methotrexate whereas constitutional symptoms was found to be highest with doxyrubicin. W hereas in radiotherapy patients subjective and objective oral symptoms increased from 10th - 30th fractionated dose of radiations and then subsequently decreased and constitutional symptoms were found to be consistent in all fractionated dosages with lowest at 50th fraction. Under combined chemo and radiotherapy patients, constitutional symptoms were highest than the oral findings. Conclusions: Cancer therapy can greatly damage the normal tissues and diminish patients quality of life and often leads to serious clinical sequelae. Therefore, therapy induced damage should be anticipated and prevented whenever possible and managed early. doi: http://dx.doi.org/10.4021/wjon581e

Abstract: Meningioangiomatosis (MA) is a rare, benign hamartomatous lesion found in cerebral cortex and leptomeninges. It occurs mostly in 5 - 15 year old children in form isolated or diffuse; the diffuse form may be associated with neurofibromatosis type 2 (NF2). The sporadic type in the adults is less common.The patient was a 37 year-old man with a long history of frontal headache. In suspected sinusitis, the patient underwent cerebral MRI that showed hypointense lesion in the right frontal lobe with heterogeneous contrast enhancement after gadolinium administration. There were no stigmata or family history of neurofibromatosis. A right pterional approach with a supraorbital craniotomy was performed. The lesion was removed with complete remission of the headache in the postoperative time. MA enters into differential diagnosis with several other diseases and a correct diagnosis is mandatory. The total surgical removal is the treatment of choice, and the prognosis after surgery is usually excellent for the absence of recurrence in sporadic cases. doi:10.4021/wjon470w

Abstract: Prostate Adenocarcinoma is one of the most commonly diagnosed cancers in the United States, with a prevalence of around 2.4 million. Patients with this disease commonly present with urinary frequency and hesitancy, nocturia, and dysuria secondary to tumor enlargement. We present the case of a 60-year-old man with multiple-site biopsy proven metastatic prostate cancer that presented with neither urological or bone related signs or symptoms. His findings were rather atypical; they included dyspnea, pancytopenia, nausea, and chills. We then detail how we narrowed our diagnosis through a systemic process of elimination, and review the general workup of an adenocarcinoma of unknown primary in a male patient.

Abstract: Uterine leiomyosarcomas do not frequently metastasize to the bone, and spinal column metastases are even less common. Surgery is the treatment of choice. Adjuvant radiation with or without chemotherapy depending on the extent of disease can be beneficial. We present the case of leiomyosarcoma metastasis to the spine with a previous history of known primary disease complicated by thrombocytopenia. Thrombocytopenia can present surgical challenges, but can also be present concurrently unrelated to the primary disease. A thorough evaluation is needed to rule out any underlying lymphoproliferative disorder or microangiopathic phenomenon.

Abstract: The malignant lymphomas rarely occur in the genito-urinary tract and particularly penis lymphomas are extremely uncommon. Frequently they do not have any specific symptoms and the diagnosis is delayed even in presence of a penis node. In our hospital we observed two patients affected by Non-Hodgkin Lymphoma (NHL), one of them with a primitive disease. Both cases were sexually active men who did not accept a radical surgery. A conservative polichemotherapy treatment by ciclophosphamide, vincristine and prednisone has been proposed and performed for both cases and a complete resolution of disease was demonstrated. At the same time we assessed the erectile function by the IIEF score, before and after treatments.

Abstract: Background: The preclinical development of anti-sarcoma drugs has been primarily based on the subcutaneous transplantation of xenografts. Transplant survival remains an obstacle of current models which has been attributed to the period of hypoxia after transplantation. We hypothesized that primary soft tissue sarcoma models with an intrinsic tissue engineered vascular supply would be easily reproducible. The aim of this study was to establish a model of primary human soft tissue sarcoma with an intrinsic vascular supply. Methods : Primary soft tissue sarcoma cells from resected human liposarcomas isolated and divided into tumour fragments were transplanted into a silicon chamber, placed around the superficial epigastric vessels in mice. Sarcoma xenograft samples were analysed histomorphologically (light / electron microscopy and immunohistochemistry). Results : All primary soft tissue sarcoma transplants engrafted, leading to solid tumours within 3 weeks. Histological and immunohistochemical staining coni¬rmed the mouse xenografts as identical high grade liposarcomas compared to original tumour tissue. Conclusion : This study established a reproducible xenograft model of primary human liposarcoma. This animal model could be of high value for studying human soft tissue sarcomas and their therapy. doi:10.4021/wjon496w Normal 0 21 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}

Abstract: We report the unusual case of a 52-year-old female with known stable metastatic ovarian cancer presenting with a new, rapidly growing gastric metastasis, leading to surgical resection. Histologic assessment of the specimen revealed evidence of submucosal and intramuscular metastatic disease originating from a metastatic lesion and not from the primary tumor. This case represents one of an otherwise rarely documented clinical scenario that a metastatic focus can itself metastasize.

Abstract: Background: To examine the agreement of Health Care Providers (HCPs) and patients` evaluation of quality of life on the Functional Assessment of Chronic Illness therapy - Palliative care module (FACIT-Pal) scale. Methods: Sixty advanced cancer patients and fifty-six health care providers involved in their care at Sunnybrook Health Sciences Centre completed a modified version of the FACIT- Pal. In the survey, patients and HCPs indicated the 10 top issues affecting the quality of life of patients with advanced cancer most profoundly. The percentage of participants selecting each item as one of their 10 most relevant items was calculated in HCPs and patients. Results: There were differences in relative rankings of QOL issues among patients and HCPs. Among the top 10 items which were identified from both patients and HCPs, there were differences in the rankings. Patients ranked emotional support from family (40.9%) as most important followed by pain (38.6%), lack of energy (31.8%) and able to enjoy life (29.6%). HCPs ranked in the following order: pain (73.2%), lack of energy (63.4%), nausea (51.2%) and dyspnea (51.2%) whereas patients rated nausea at 18.2 % and dyspnea at 9.09%. Conclusion: There is a discrepancy between scores of patients and HCPs as they may prioritize differently. HCPs tended to put more emphasis on physical symptoms, whereas patients had emotional and global issues as priorities. doi: http://dx.doi.org/10.4021/wjon578w

Abstract: Few cases of primary cardiac lymphoma (PCL) are found in the literature. We report the case of an 85 year-old male who presented with cardiac tamponade and effusive-constrictive pericarditis secondary to primary cardiac lymphoma involving only the pericardium. There have been no prior published cases with these rare scenarios.

Abstract: We report a case of an 82 years old female with Non-Hodgkin Lymphoma (NHL) in remission whom underwent a transhiatal esophagectomy (THE) for esophageal adenocarcinoma. The post-operative course was complicated by severe chylothorax requiring an additional thoracotomy for ligation of the thoracic duct. The influence of the patient's history of NHL on the development of such a severe chylothorax is under question.
