Treatment sequence in patients with neuroendocrine tumours: a nationwide multicentre, observational analysis of the Swiss neuroendocrine tumour registry.

BACKGROUND: In recent years, several treatment modalities have proved to be effective in the treatment of neuroendocrine tumours (NETs). However, there is currently no consensus on the sequence in which these options are best used. METHODS: In this observational study, we analysed the treatment modalities and sequences of all patients included in the Swiss NeuroEndocrine Tumour registry (SwissNET). SwissNET is a national registry, which has prospectively included patients with a NET from all regions of Switzerland since 2008. RESULTS: The registry includes 1366 patients; 1063 had documented therapies after the main diagnosis and were included in the analysis. The median follow-up time was 1.86 years. The most common primary site was the small intestine (291 patients, 27%) followed by pancreas (254 patients, 24%), lung (172 patients, 16%) and appendix (163 patients, 15%). A total of 167 different therapy sequences were observed. In 708 (67%) patients, surgery was the only treatment. The sequence of surgery followed by chemotherapy was most frequently documented in poorly (G3) differentiated (24 patients, 60%) and pancreatic (15 patients, 34%) NETs. Tumours treated with surgery followed by biotherapy or followed by peptide receptor radionuclide therapy (PRRT) were predominantly well-differentiated G1 NETs of the small intestine. In patients who were treated with either PRRT or systemic therapy (chemotherapy or molecular therapy) or both, PRRT was used more frequently than systemic therapy in patients with a small intestinal NET (35 patients, 62% vs 30, 54%), whereas the opposite held true in pancreatic (44 patients, 59% vs 56, 70%) and lung NETs (6 patients, 14% vs 40, 97%). If both chemotherapy and molecular therapy were used, chemotherapy was applied prior to molecular therapy in 13 of 19 (68%) patients with a pancreatic NET. CONCLUSION: Surgery represents the treatment of choice in most patients with a NET irrespective of tumour stage. In patients receiving additional treatment, an impressive variety of treatment sequences were documented. In small intestinal NETs, patients received PRRT more often than chemotherapy, whereas the opposite holds true for patients with pancreatic and lung NETs.

Novel Prognostic Factors in Resected Small Bowel Adenocarcinoma.

BACKGROUND: Small bowel adenocarcinoma (SBA) is a rare malignancy affecting approximately 3000 patients per year in the United States, and there is limited evidence prognosticating patients with resected SBA. We aimed to evaluate prognostic factors and the role of adjuvant therapy in patients with resected SBA. PATIENTS AND METHODS: Two hundred forty-one patients who had resected stage I-III SBA were retrospectively identified at a single tertiary referral institution. Overall survival (OS) analysis was performed by the Kaplan-Meier method, and Wilcoxon tests were used for statistical comparisons. Cox proportional hazards were performed to identify significant variables by univariate and multivariate analysis. RESULTS: Median OS for the entire group was 54.5 months (95% confidence interval [CI], 37.2-81.2 months), with 5- and 10-year OS of 48% and 35%. Median follow-up was 113.7 months (95% CI, 97.9-126.6 months). For patients with stage III disease who received adjuvant therapy, the median OS was 33.8 months (95% CI, 27.8-78.8) compared to 24.7 months (95% CI, 11.5-37.8) for patients with no adjuvant therapy (P < .01). Male sex, advanced T stage, advanced N stage, increased positive lymph node ratio, lymphocyte-to-monocyte ratio < 1.56, presence of residual disease, and earlier date of diagnosis predicted worse survival on univariate analysis. Age > 60 years, lymphocyte-to-monocyte ratio < 1.56, and advanced T stage were identified as independent negative predictors of OS for all patients by multivariate analysis. CONCLUSION: Advanced age, advanced T stage, and lymphocyte-to-monocyte ratio < 1.56 independently predicted survival in resected SBA. Adjuvant therapy is associated with improved survival in patients with resected stage III SBA.

Hospital readmission rates and risk factors for readmission following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal surface malignancies.

BACKGROUND: Cytoreductive surgery and Hyperthermic intra-peritoneal chemotherapy (CRS/HIPEC) for peritoneal surface malignancies is associated with high morbidity. The increased numbers of patients undergoing CRS/HIPEC in recent years mandates risk analysis and quality assurance. However, only scarce data exist regarding causative parameters for readmission. The aim of this study was to assess readmission rates and risk factors associated with readmission. METHODS: A retrospective-cohort study including patients from two high-volume centers who underwent CRS/HIPEC surgery between the years 2007-2016 was performed. Patients' demographics, peri-operative data and readmission rates were recorded. RESULTS: 223 patients were included in the study. The 7 and 30-day readmission rates were 3.5% (n = 8) and 11% (n = 25), respectively. Late readmission rates (up to 90 days) were 11% (n = 25). The most common causes of readmission were surgical related infections (35%), small bowel obstruction (17.5%) and dehydration (14%). Post-operative complications were associated with higher readmission rates (p = 0.0001). PCI score was not associated with higher rates of readmission. CONCLUSION: Readmissions following CRS/HIPEC occur mainly due to infectious complications and dehydrations. Patients following CRS/HIPEC should be discharged after careful investigation to a community based continuing care with access for IV fluid replacement or antibiotics administration when required.

Cytoreductive Surgery Plus Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Metastases From a Small Bowel Adenocarcinoma: Multi-Institutional Experience.

BACKGROUND: The multi-institutional registry in this study evaluated the outcome after cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with peritoneal metastases (PM) from small bowel adenocarcinoma (SBA). METHODS: A multi-institutional data registry including 152 patients with PM from SBA was established. The primary end point was overall survival (OS) after CRS plus HIPEC. RESULTS: Between 1989 and 2016, 152 patients from 21 institutions received a treatment of CRS plus HIPEC. The median follow-up period was 20 months (range 1-100 months). Of the 152 patients, 70 (46.1%) were women with a median age of 54 years. The median peritoneal cancer index (PCI) was 10 (mean 12; range 1-33). Completeness of cytoreduction (CCR) 0 or 1 was achieved for 134 patients (88.2%). After CRS and HIPEC, the median OS was 32 months (range 1-100 months), with survival rates of 83.2% at 1 year, 46.4% at 3 years, and 30.8% at 5 years. The median disease-free survival after CCR 0/1 was 14 months (range 1-100 months). The treatment-related mortality rate was 2%, and 29 patients (19.1%) experienced grades 3 or 4 operative complications. The period between detection of PM and CRS plus HIPEC was 6 months or less (P = 0.008), and multivariate analysis identified absence of lymph node metastasis (P = 0.037), well-differentiated tumor (P = 0.028), and PCI of 15 or lower (P = 0.003) as independently associated with improved OS. CONCLUSION: The combined treatment strategy of CRS plus HIPEC achieved prolonged survival for selected patients who had PM from SBA with acceptable morbidity and mortality.

Synchronous peritoneal metastases of small bowel adenocarcinoma: Insights into an underexposed clinical phenomenon.

BACKGROUND: The aim of this population-based study was to provide insight into the incidence, risk factors and treatment-related survival of patients with peritoneal metastases (PM) of small bowel adenocarcinoma (SBA). METHODS: Data from the Netherlands Cancer Registry were used. All patients diagnosed with SBA between 2005 and 2014 were included. The influence of patient and tumour characteristics on the odds of developing PM was analysed. Subsequently, for all further analyses, patients without synchronous PM of SBA were excluded. The log-rank test and Kaplan-Meier analyses were conducted to estimate survival, and the Cox proportional hazards model was used to evaluate the risk of death. RESULTS: Of the 1428 included patients diagnosed with SBA, 181 (13%) presented with synchronous PM. Synchronous PM was found in 9% of the duodenal tumours and in 17% of the more distal tumours. Median overall survival of all patients with PM was 5.9 months, whereas survival of both 11 months was observed in patients treated with primary tumour resection or palliative chemotherapy and 32 months after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS+HIPEC). Poor prognostic factors for survival were age ≥70 years (hazard ratio [HR] 1.6, 95% confidence interval [CI] 1.1-2.2), systemic metastases other than PM (HR 2.0, 95% CI 1.4-2.9) and an advanced (HR 1.9, 95% CI 1.3-3.0) or unknown T-stage (HR 2.1, 95% CI 1.2-3.5). CONCLUSIONS: Synchronous PM was frequently encountered in SBA. Without treatment, prognosis was extremely poor. Survival was higher after primary tumour resection, palliative chemotherapy and CRS+HIPEC, but selection bias probably played a significant role calling for further clinical research.

Management of Well-differentiated Gastroenteropancreatic Neuroendocrine Tumors (GEPNETs): A Review.

PURPOSE: Neuroendocrine tumors (NETs) are heterogeneous tumors that arise from the neuroendocrine cells of the digestive tract and other organs, such as the lung, ovary, and thyroid glands. They can be well differentiated or poorly differentiated, and management of these tumors differs for each histologic subtype. We have performed a review of NETs and focused on management of well-differentiated gastroenteropancreatic neuroendocrine tumors (GEPNETs) and carcinoid syndrome. METHODS: A PubMed search was performed to obtain articles on the management of well-differentiated NETs. Using the key words neuroendocrine tumors, carcinoid, pNET, octreotide, somatostatin analogues, and radiolabeled therapy, we reviewed Phase II and III trials that were published over the past 30 years. We also reviewed guidelines from the European Neuroendocrine Tumor Society, North America Neuroendocrine Tumor Society, and National Comprehensive Cancer Network in our search. FINDINGS: NETs are usually slow-growing tumors that remain asymptomatic for a long duration and can be either nonfunctioning or functioning. Surgical resection is recommended for locoregional disease, impending obstruction, symptom control, and advanced disease. Nonsurgical treatment options include somatostatin analogues (SSAs), multikinase inhibitors, targeted therapy, chemotherapy, and radiolabeled SSAs. Carcinoid syndrome is mainly treated with SSAs. IMPLICATIONS: Although GEPNETs are slow-growing tumors, most patients are diagnosed with metastatic disease, and therefore it is important that the management of each patient be discussed in a multidisciplinary setting to optimize the treatment strategy. Patients should be considered for clinical trials and refractory cases referred to a specialty center.

Recurrence and Survival Outcomes After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Small Bowel Adenocarcinoma.

BACKGROUND: Peritoneal dissemination of small bowel adenocarcinoma (SBA) is rare but is associated with a dismal prognosis. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a promising treatment option. We evaluated our experience of CRS-HIPEC for the treatment of SBA. PATIENTS AND METHODS: Sixteen consecutive patients underwent CRS-HIPEC for small bowel malignancy between 2003 and 2016. Clinopathological and treatment-related factors were obtained from a prospective database. The study's endpoints of disease-free (DFS) and overall (OS) survival were evaluated using the Kaplan-Meier method. Prognostic variables were identified through univariate and multivariate analyses. RESULTS: Follow-up was complete in all patients. The median follow-up was 20.6 (range=0.2-62) months. The was no in-hospital mortality and grade III/IV morbidity was 25%. The median OS after CRS-HIPEC was 24.7 months, with a 36-month survival of 34%. The median DFS was 11.3 months, with a 36-month DFS of 8%. Two factors were associated with a poorer OS on univariate analysis; only peritoneal cancer index >10 was associated with a poorer OS on multivariate analysis (p=0.032). CONCLUSION: CRS-HIPEC in selected patients with peritoneal dissemination of SBA is associated with reasonable mid-term survival outcomes but treatment failure is common. High disease burden, quantified by the PCI is associated with poor outcomes. A large, prospective, multi-institutional study is needed to further evaluate the outcomes of CRS-HIPEC for SBA.

[Consensus and controversy of endoscopic diagnosis and treatment of gastroenteropancreatic neuroendocrine tumors].

Neuroendocrine neoplasms(NENs) are relatively rare tumors originating from the diffuse neuroendocrine system, and gastrointestinal tract is one of the most common location of the tumors. Currently, the European Neuroendocrine Neoplasm Society (ENETS) and the National Comprehensive Cancer Network (NCCN) have released the international guidelines for NENs management. And also, experts from Chinese Society of Clinical Oncology (CSCO) have proposed "The Consensus on Gastroenteropancreatic Neuroendocrine Neoplasm in China" in 2016, which is also one of the most important reference standard for the diagnosis and treatment of gastroenteropancreatic(GEP) NENs in China. Here we will interpret these three guidelines or consensus. There are few controversies about endoscopic management principle for GEP-NEN of different locations and sizes among these three guidelines or consensus, but for small NENs without involving intrinsic muscularis, endoscopic resection is recommended and considered. We hope that this interpretation may help clinicians for clinical decision making.

Prognostic factors of hemorrhagic complications after oxaliplatin-based hyperthermic intraperitoneal chemotherapy: Toward routine preoperative dosage of Von Willebrand factor?

BACKGROUND: Oxaliplatin-based hyperthermic intraperitoneal chemotherapy (HIPEC-ox) induces specific morbidity with hemorrhagic complications (HC). The aim of this study was to identify preoperative, intraoperative and postoperative HC predictive factors after HIPEC-ox. METHODS: A prospective single center study that included all consecutive patients treated with curative-intent HIPEC-ox, whatever the origin of peritoneal disease, was conducted. All patients underwent systematic blood tests exploring primary hemostasis and endothelial activation before surgical incision (D0) and on postoperative days 2 (POD2) and 5 (POD5). RESULTS: Between May 2012 and August 2015, 47 patients were enrolled in the study. The overall HC rate was 38%. Major morbidity was significantly higher in patients with HC. Patients presenting HC were significantly more often affected with pseudomyxoma peritonei and had less preoperative chemotherapy. Multivariate analysis showed that a higher plasmatic level of Von Willebrand factor antigen at D0 (D0 VWF:Ag) was a protective predictive factor for HC (p = 0.049, HR: 0.97 CI 95% [0.94-1.00]). A D0 VWF:Ag level below 138% had a sensitivity of 87.5%, a specificity of 67% and an area under the curve of 80.3% (CI 95% [66.5-94], p < 0.01) for predicting HC. CONCLUSIONS: Through the identification of prognostic factors, this study highlighted a subgroup of patients with low risk of HC after HIPEC-ox. Based on these results, we propose a routine preoperative dosage of VWF that would help the surgeon to select the most suitable patients for HIPEC-ox.

The incidence of over-the-counter medication use in patients with midgut neuroendocrine tumors.

Recent increases in the use of over-the-counter (OTC) medicines and the underreporting of the use of these medications to physicians have sparked interest in the number and types of "supportive" therapies used by patients with neuroendocrine tumors (NETS). Patients with NETS are of special interest as a result of the potential interactions/interferences between tumor-associated peptide and amine production and OTC supplements. A prospective analysis of patients with primary small bowel NETS between 1998 and 2012 was conducted to define and catalog each patient's prescription and OTC medication use at each clinic visit. The most recently recorded patient medications were used for this analysis. Three hundred sixty-two patients with small bowel primary NETS were studied. One hundred eighty-seven patients (51.6%) were taking nutritional supplements. Of these taking supplements, the per cent of patients taking one, two, three, or more than three supplements was 28.3, 24.1, 22.5, and 25.1 per cent, respectively. Females (n = 109) were more likely to take supplements in comparison to males (n = 78; P = 0.037). Fifty one patients (14.1%) took proton pump inhibitors and 31 patients (8.6%) took loperamide. OTC supplements were used by 50 per cent of patients with primary small bowel NETS in this study. Over one-third of our patients reported using three or more OTC medicines daily. These medicines have the potential to interact with the metabolism of prescribed medicines, modify ability to clot during surgery, exacerbate NET symptoms, and alter NET markers. Given the prevalence of OTC medications and their potential actions, it is important to carefully catalog their use.

Small intestinal adenocarcinoma: rarely considered, often missed?

Adenocarcinoma of the small intestine is rare in comparison with other gastrointestinal malignancies but its incidence is rising. It often presents at an advanced stage due to the non-specific symptomatology. More recent advances in small intestinal visualisation including video capsule endoscopy and double balloon enteroscopy may facilitate diagnosis in patients with suspected small intestinal neoplasia. At present aggressive surgical resection provides the best chance of cure of small intestinal adenocarcinoma. Despite apparent curative resection the long-term outlook remains poor. The role of adjuvant chemotherapy is not well defined due to the rarity of the disease and lack of randomised controlled trials; however, there appears to be a survival benefit in advanced disease with the use of oxaliplatin and 5-fluorouracil. We reviewed the clinical aspects of this aggressive condition focusing on the pathological associations, available diagnostic modalities and current management options. Three cases are included to illustrate the review.

Primary intestinal lymphoma in patients with inflammatory bowel disease: a descriptive series from the prebiologic therapy era.

BACKGROUND: Primary intestinal lymphoma in the setting of inflammatory bowel disease (IBD) is uncommon and may be associated with immune suppressive therapy. We report clinical features and outcomes in patients with both conditions prior to use of biologic therapy. METHODS: All patients with primary intestinal lymphoma and IBD at our institution from 1960-2000 were retrospectively identified. Data reported are frequency (proportion) or median (interquartile range). Kaplan-Meier analysis was performed. RESULTS: Fifteen patients were identified: 14 (93%) were male, 10 (66%) had Crohn's disease. Median age at diagnosis of IBD and lymphoma was 30 (22-51) and 47 (28-68) years, respectively, with bloody diarrhea the most common presenting symptom for each diagnosis. Lymphoma location was colorectal in nine (60%), small bowel in four (27%), and one (6.25%) each: stomach, duodenum, and ileal pouch. Treatments were surgery plus chemotherapy (n = 6), surgery alone (n = 3), chemotherapy alone (n = 2), chemotherapy and radiation (n = 1), surgery and radiation (n = 1); two patients died before treatment. Most patients (n = 11, 73%) were Ann Arbor stages I or II. Large cell B-type histology was most common (n = 9, 60%). Three patients died within 30 days of lymphoma diagnosis. Survival free of death from lymphoma at 1- and 5-years was 78% and 63%, respectively, and was associated with advanced lymphoma stage (P = 0.004). CONCLUSIONS: Diagnosis and treatment of primary intestinal lymphoma in patients with IBD can be challenging and requires a high index of suspicion. Optimal survival requires multimodality therapy.

Unexplained iron deficiency anaemia: Is it worthwhile to perform capsule endoscopy?

BACKGROUND: In around 30% of iron deficiency anaemia (IDA) cases a definite diagnosis cannot be made. AIM: To investigate the role of capsule endoscopy (CE) in detecting lesions in patients with unexplained IDA after a negative endoscopic, serologic and haematologic diagnostic work up and its possible role in influencing clinical outcome. METHODS: 138 patients suffering from IDA were identified among 650 consecutive patients undergoing CE at our unit. RESULTS: CE revealed the following positive findings in 91/138 patients: angiodysplasias in 51 patients; jejunal and/or ileal micro-ulcerations in 12; tumours/polyps in 9; erosive gastritis in 4; Crohn's disease in 5; jejunal villous atrophy in 5; a solitary ileal ulcer in 1 and active bleeding in the last 4 patients. Follow up data were available for 80/91 patients (87.9%). In 15 out of 46 patients with angiodysplasias IDA spontaneously resolved without any treatment; 9 patients required iron supplementation; 10 patients healed after lanreotide administration; APC was performed in 9 out of 46 patients and 3 patients underwent regular blood transfusion without any success on IDA. 10 out of the 12 patients with small bowel micro-ulcers spontaneously recovered from IDA whilst 2 patients after iron supplementation. All 9 patients affected by tumours/polyps were surgically addressed. In all erosive gastritis cases, patients recovered from IDA after PPI and Helicobacter pylori eradication. Four patients with Crohn's disease diagnosis restored to health with medical therapy. One out of the 4 patients with jejunal villous atrophy and the sole patient with a solitary ileal ulcer spontaneously healed. In 1 out of 3 patients with active bleeding IDA resolved without further treatment after blood transfusion whilst 2 patients were referred for surgical treatment. At follow up, complete resolution of IDA was achieved in 96.25%. CONCLUSIONS: Small bowel investigation is a matter of great importance in IDA patients after negative upper and lower gastrointestinal endoscopy.

[A case report of primary adenocarcinoma of small intestine].

This is an account of a case of primary adenocarcinoma of the small intestine with peritoneal dissemination successfully treated with chemotherapy. A 64-year-old woman was admitted with a complaint of severe abdominal distension. Abdominal computerized tomography revealed a bowel obstruction with tumor and the remarkable small bowel dilation of oral side of tumor. The tumor was found at surgery to be at the ileum 15 cm proximal from the ileocecal region. Peritoneal dissemination was recognized around the ileocecal region, so ileum partial resection was performed for the primary cancer lesion and dissemination region. Pathological diagnosis of the resected specimen was adenocarcinoma with lymph nodes metastasis. The peritoneal dissemination consisted of metastatic adenocarcinoma from small intestine. After an operation, internal use of S-1 was performed as adjuvant chemotherapy. But a recurrent lesion at the ovarium was detected 6 months after surgery. The patient was subsequently treated with resection of the ovarium. For lung metastasis, the combination chemotherapy with mFOLFOX6 + bevacizumab was administered. Primary small intestinal adenocarcinoma is a rare disease, and it is often diagnosed as advanced cancer because of few characteristic symptoms. So carcinoma of the small intestine usually has a poor prognosis.

[Visualisation methods for etheric formative forces]. / Die "bildschaffenden" Methoden der anthroposophischen Medizin (I). Eine kritische Analyse.

UNLABELLED: Rudolf Steiner, the founder of anthroposophy, suggested the development of visualisation methods for "etheric formative forces". The essential methods, their "spiritual scientific" basis and indications are described and their claims critically tested. SUMMARY: The methods are not validated, the key criteria for diagnostic tests (reproducibility, sensitivity, specifity) are not given.

[Hyperthermic intraperitoneal chemotherapy for the treatment of peritoneal carcinomatosis arising from gastric cancer]. / Chimiohyperthermie intrapéritonéale dans le traitement des carcinoses péritonéales d'origine gastrique.

Since 20 years, treatment of peritoneal carcinomatosis has been developed in expert centers. Cytoreductive surgery and perioperative intraperitoneal chemotherapy, especially hyperthermic intraperitoneal chemotherapy, was assessed by many nonrandomised studies for the treatment of peritoneal carcinomatosis arising from gastric cancer. Results described increased survival, especially for the most favourable cases: limited carcinomatosis and complete cytoreductive surgery. A strict selection of the patients is necessary because of the important morbidity of those treatments. Only patients with good general health, able to tolerate a threatening treatment, with possible complete cytoreduction, may benefit from those treatments. Many japanese studies had demonstrated the efficacy of hyperthermic intraperitoneal chemotherapy for the prophylactic treatment of carcinomatosis in advanced-gastric cancers. These results have to be confirmed by european randomised studies.

Supportive-expressive group therapy for women with metastatic breast cancer: survival and psychosocial outcome from a randomized controlled trial.

BACKGROUND: Mixed reports exist about the impact of supportive-expressive group therapy (SEGT) on survival. METHODS: From 485 women with advanced breast cancer recruited between 1996-2002, 227 (47%) consented and were randomized within an average 10 months of cancer recurrence in a 2:1 ratio to intervention with 1 year or more of weekly SEGT plus three classes of relaxation therapy (147 women) or to control receiving three classes of relaxation therapy (80 women). The primary outcome was survival; psychosocial well-being was appraised secondarily. Analysis was by intention-to-treat. RESULTS: SEGT did not prolong survival (median survival 24.0 months in SEGT and 18.3 in controls; univariate hazard ratio for death 0.92 [95% CI, 0.69-1.26]; multivariate hazard ratio, 1.06 [95% CI, 0.74-1.51]). Significant predictors of survival were treatment with chemotherapy and hormone therapy (p<0.001), visceral metastases (p<0.001) and advanced disease at first diagnosis (p<0.05). SEGT ameliorated and prevented new DSM-IV depressive disorders (p = 0.002), reduced hopeless-helplessness (p = 0.004), trauma symptoms (p = 0.04) and improved social functioning (p = 0.03). CONCLUSIONS: SEGT did not prolong survival. It improved quality of life, including treatment of and protection against depression.

De novo CD5+ diffuse large B cell lymphoma with basophilia in the peripheral blood: successful treatment with autologous peripheral blood stem cell transplantation.

Basophils play an important role in allergic inflammation and are pathologically related to hematological disturbances, such as iron deficiency anemia and myeloproliferative disorders; however, they are only rarely encountered in lymphoid malignancies. Here, we report the case of a 33-year-old man with a bulky mass of the small intestine, multiple paraaortic lymphoadenopathy, pleural effusion, and ascites, who was diagnosed as a case of de novo CD5+ diffuse large B cell lymphoma (DLBCL). This patient showed a marked elevation of the basophil count in the peripheral blood, which appeared to run in parallel with the tumor burden. High dose chemotherapy followed by autologous peripheral blood cell transplantation yielded complete remission, and the patient has remained disease free for 5 years. To the best of our knowledge, this is the first report of a case of de novo CD5+ DLBCL showing marked elevation of the PB basophil count.

Bowel cancer - guide for the GP.

BACKGROUND: Many patients will remain asymptomatic until the advanced stages of colorectal cancer and hence, will only be identified by means of a coordinated screening program. OBJECTIVE: This article outlines the risk assessment, early detection primary prevention and management of colorectal cancer. DISCUSSION: It is vital that general practitioners recognise the enormous variation in the patterns of clinical presentation of colorectal neoplasia such as rectal bleeding, iron deficiency anaemia, change in bowel habit, and unexplained weight loss. Any patient over 40 years of age presenting with rectal bleeding should be considered for colonoscopy. In patients in whom a colorectal neoplasm has been diagnosed, preoperative workup and counselling is of paramount importance. Primary treatment of colorectal cancer is surgical resection and often adjuvant chemotherapy. Patients with rectal tumours have a greater risk of complications of surgery and local recurrence than those with colonic tumours. Patients with node positive cancer remain at significant risk for recurrence, despite optimal surgery and removal of the primary tumour. Adding oxaliplatin to standard (5FU based) chemotherapy has improved disease free survival for high risk patients.
