Multiple myeloma is a malignant plasma cell proliferation located in the bone marrow and bones. It can secondarily manifest with extraosseous involvement, but the gastro-intestinal tract locations are rare. We report 3 cases of gastric and colonic localizations of myeloma in two males and one female, aged 66, 71 and 77years. Multiple myeloma had been diagnosed 1 to 7years before. Digestive symptoms were epigastric pain, rectal bleeding or an obstructive syndrome. Endoscopy revealed ulcerated and budding tumors in the stomach, and nodular pseudo-polypoid tumor formations or an ulcerated erythematous area in the colon. Histopathological examination of the biopsies showed a diffuse tumor cell proliferation in the lamina propria composed of cells with a plasmacytoid or plasmablastic appearance, expressing plasma cell markers such as CD138 on immunohistochemistry. The 3 patients died in the weeks following the diagnosis. The prognosis of digestive localizations of multiple myeloma remains very poor despite new therapies. In the presence of any digestive symptoms in these patients with multiple myeloma, more systematic endoscopy may allow an earlier diagnosis and the implementation of more effective therapies., (Copyright © 2024 Elsevier Masson SAS.

Colonic lymphoma is a rare malignant gastrointestinal tumor that can be revealed by an exceptional and serious complication: intestinal obstruction. Treatment is based on surgery and chemotherapy. We here report a case of diffuse colonic large B-cell lymphoma revealed by occlusion and diagnosed based on the examination of surgical specimen in a 64-year-old man who was in complete remission after six courses of R-CHOP., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts., (Copyright: Mohamed Zioui et al.)

Synchronous presentation of a colonic adenocarcinoma and lymphoma is extremely rare. We describe here, the sixth observation of a marginal zone B-cell lymphoma, which was incidentally diagnosed in a 77-year-old patient, who was operated for adenocarcinoma of hepatic flexure. This case shows the importance to be aware of this rare association and highlights the dilemma of its management., (Copyright © 2022 Elsevier Masson SAS. All rights reserved.)

The management of colorectal cancer (CRC) relies heavily on TNM staging. In order to improve this staging, it is essential to identify all histological markers bearing a significant prognostic value. Among these, tumor deposits (TDs), defined as tumor foci in the pericolonic or perirectal adipose tissue with no residual lymph node tissue, have been shown to be associated with poor prognosis in cohort studies leading to their individualization in the TNM7 classification as pN1c. However, TDs are only considered in the absence of lymph node metastases. There is no consensus on this particular way of integrating TDs in the TNM classification. Indeed, at the time when the choice of the type of adjuvant treatment and its duration in stage III colon cancers (i.e. with lymph node metastases) is based on pT and pN criteria, taking into account TDs only in the absence of concomitant lymph node metastases is potentially responsible for a misclassification of some patients and wrong therapeutic decisions. In addition, many questions concerning the true definition of TDs, their origin, their prognostic value and the optimization of their consideration remain open. The objective of this review is to provide a synthesis of current knowledge on TDs in CRC, in view of their prognostic importance, their biological complexity and the scientific interest they are currently the subject of., (Copyright © 2021 Elsevier Masson SAS.

Background: Return-to-work after cancer depends on several factors related to the disease but also other socio-professional factors. The primary aim of this study was to identify socio-demographic, disease related and professional factors influencing the return-to-work process., Methods: It was a prospective and descriptive study reporting the return-to-work process in 89 cancer patients, in a professional activity age, who had cancer treatment and a follow up in the Oncology department in Tahar Maamouri Teaching Hospital of Nabeul, between September 2015 to December 2019., Results: Our study included 89 patients. Mean age was 45 years±8. The population was predominantly feminine (59 %). They were employees in 45 % of cases. Private professional sectors included 60 % of all patients. An open-ended contract was performed in 87 % of cases. Most frequent primary tumors were breast tumors (45 %) and colon tumors (20 %). Thirty-four patients went back to work after recovery. Seventy-nine percent of them were female patients and 70 % had breast cancer. Predictive factors identified in univariate statistical analysis and correlated to return-to-work were gender (P=0.002), occupation (P<10 -3 ), initial duration off sick (P=0.015), fitting out measures at work (P=0.01), primary tumor origin (P=0.01), disease stage (P=0.037), treatment (P=0.014) and disease outcome after treatment (P=0.024)., Conclusion: Our study underlined a need to create a pluridisciplinary platform unifying collaborators among oncologists and occupational health professionals in order to enhance professional reintegration process and to hold patient's professional equilibrium after cancer recovery., (Copyright © 2020 Société Française du Cancer.

Dysplasia is a preneoplastic lesion. Histological diagnosis is based on the presence of architectural and cytological modifications, and dedifferentiation, which the intensity is variable. Dysplasia is commonly graded as low and high grade. We achieved a retrospective study of 90 cases of gastrointestinal dysplasia collected in the Department of Pathology of Hassan II university hospital of Fez, during a period of 3 years. The cases were reviewed independently and blindly without clinical information by two pathologists. Their diagnoses were compared to the initial diagnosis. Interobserver concordance in the diagnosis of the degree of dysplasia was evaluated. The average age of our patients was 56 years oldwithout predominance of sex. The interobserver concordance in the diagnosis of digestive dysplasia between the three pathologists was moderate (with a Kappa estimated at 0.42). Concordant diagnosis for digestive low grade dysplasia was observed in 50 cases of the 55 cases (90%) and only 18 cases of high-grade dysplasia of 35 cases studied (50%). The agreement for the low-grade dysplasia is more significant. However, there is significant variation in the analysis of high-grade dysplasia. This work reveals a moderate reproducibility in the diagnosis of gastrointestinal dysplasia lesions and mostly well marked for high-grade dysplasia., (Copyright © 2019 Elsevier Masson SAS.

Gastrointestinal tract ganglioneuromatosis is a rare condition, which is isolated or included in a syndromique disease. Multiple endocrine neoplasia type 2 is the most frequently associated syndrome. Association with type 1 neurofibromatosis has also been established, but much rarely. We report the case of large bowel ganglioneuromatosis found incidentally in a patient with type 1 neurofibromatosis., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

Macrophage activation syndrome is a state of hyper-inflammation that results from increased secretion of proinflammatory cytokines, responsible of the inappropriate activation and proliferation of cells from the lymphohistiocyte lineage. It associates clinical signs, biological abnormalities and images of haemophagocytosis. It is a rare but serious attack, that can be "primary" or "secondary" to an infection, neoplasia, or autoimmune disease. Cancer etiology by solid tumor is exceptional. We report here a case of MAS that revealed a colon carcinoma with medullary metastasis in a 62 years old patient. MAS can complicate or reveal a solid tumor in only 1.6% of cases, especially when there is spinal metastasis. This association has rarely been reported in the literature, and only in isolated cases. Moreover, in our patient reports the metastases of colon cancer are located in the bone, which is less frequent than liver and lung metastases. MAS is a serious pathology with high mortality, associated with inappropriate activation of the immune system. Etiological treatment is necessary and may be sufficient.

The MSI phenotype in colon cancer is a good prognostic factor, with an impact probably more pronounced for stage II than stage III tumor. This survival advantage may be related to the tumor-infiltrating lymphocytes observed in MSI tumors, thus explaining the existence of a probably more effective anti-tumor immune response. In addition, the MSI status would also be a biomarker able to predict the lack of efficacy of adjuvant 5-fluorouracil (5FU) chemotherapy. In contrast, as observed in MSS colon cancer, the MSI tumors would have a survival benefit with the addition of oxaliplatin to adjuvant 5FU chemotherapy. Based on these data, the "French National Thesaurus of Digestive Oncology" suggests for patients with MSI colon cancer, an adjuvant chemotherapy combining fluoropyrimidine and oxaliplatin for stage III, and surgery alone without adjuvant chemotherapy for stage II (excepted for pT4b tumors in which the combination of fluoropyrimidine and oxaliplatin may be a therapeutic option). Beyond these recommendations, the discussion of adjuvant treatment in MSI tumors should also include other factors such as the patient's age and comorbidities. The duration of the adjuvant treatment (3 or 6 months) and the regimen used (FOLFOX or XELOX) should be based on the recommendations of the international IDEA consortium pending the results of the translational studies of this trial. Finally, the promising results of immunotherapy in metastatic MSI colorectal led to the development of clinical trials evaluating "immune checkpoint blockers" in combination with FOLFOX in the treatment of stage III MSI colon cancer., (Copyright © 2018 Société Française du Cancer.

Microsatellite instability (MSI) is a predictive biomarker for the efficacy of immune checkpoint inhibitors, regardless of the tumor type. While clinical characteristics of MSI cancer patients have been largely described in tumor localizations frequently associated with this genetic phenotype (i.e. colorectal cancer, endometrial cancer), it remains poorly characterized in other neoplasms. Pan-tumor high-throughput genome sequence analyses have contributed to the broadening of knowledge about the landscape of MSI. This review aims at synthetizing the literature concerning the frequency of MSI status in solid cancers, according to the cancer stage and the hereditary or sporadic origin of the mismatch repair deficiency. We then check for other cancers frequently associated with MSI and describe the clinical and pathological characteristics that should suggest a MSI phenotype., (Copyright © 2018 Société Française du Cancer.

The aim of our study was to assess the value of Elastic stain in the diagnosis of venous invasion (VI) in colonic adenocarcinoma., Material and Methods: All patients who undergone surgery for colonic adenocarcinoma at the University Hospital of Amiens, between 2004 and 2007, were included. Hematein-phloxin-saffron (HPS) stained slides of colectomy specimens were reviewed by two pathologists. Tumor blocks were stained with Elastic Stain (Roche - Ventana ® ). The presence or absence of VI, their number and localization were correlated with overall survival., Results: Two hundred and thirty-one cases were investigated and 3274 slides were examined. VI were more often diagnosed by Elastic Stain than HPS stain (66% vs. 40%). Ninety percent of VI were revealed within the first 6 HPS slides, and from the first 5 in Elastic Stain. The presence of VI revealed by Elastic Stain and/or HPS was significantly associated with decreased overall survival in multivariate analysis (P=0.029), especially for stage IIA tumors (P=0.016). Tumor differentiation (P=0.006) and pTNM stage (P=0.001) were also independent prognostic factors. The localization and the number of VI were not prognostic factors., Conclusion: Our study confirms the prognostic value of VI, revealed by an elastic stain, in colonic adenocarcinoma. A systematic elastic stain of all tumor blocks (number at least 5) could be considered in the future, during pathological examination of colectomy for adenocarcinoma., (Copyright © 2018 Elsevier Masson SAS.

The therapeutic management of malignant colorectal polyp with endoscopic resection is mainly based on specific histopathological criteria. The quality of these criteria is strongly linked to the management of the endoscopic specimen. The French Pathology Society drafted a standardized pathological report with guidelines for the macroscopic management of the endoscopic specimen and explanatory notes for each histopathological criteria. These guidelines are based on the TNM AJCC/UICC classification, 8th edition and the WHO 2010 classification of colorectal tumors, the recommendations of the French Society of Digestive Endoscopy, the synthesis of the literature and on international consensus for prognostic criteria. The pathological report of a malignant colorectal polyp must clearly mention: the histological type and the size of the polyp, the pT stage and the following five prognostic criteria: the value of the resection margins, the level of tumor invasion into the submucosa, the grade of the tumor, the absence or presence of vascular emboli and of tumor budding., (Published by Elsevier Masson SAS.)

Objective: To study the epidemiology and histology of primary digestive cancers in semi-urban areas in Burkina Faso., Methods: This was a descriptive study over 5 years conducted simultaneously in 2 regional hospitals in Burkina Faso. It included all patients treated for primary digestive cancers., Results: A total of 352 were included. The average age of the patients was 44.3 years. Patients aged between 30 and 49 years accounted for 44.6%. There were 175 male patients (49.7%). In the patient's history, we found 6 cases of ulcerative colitis, 2 cases of colonic adenoma, and 5 cases of hepatic cirrhosis. The average consultation time was 138 days. In 70 cases (19.9%), the cancer was discovered at a stage of complication. The most affected organs were the colon and rectum (36.7%), the stomach (21.9%) and the pancreas (19.0%). The most common histological type of cancer was adenocarcinoma (67.6%). One hundred and forty-four patients (40.9%) were diagnosed at stage 3 and 65 others (18.5%) at stage 4 of TMN staging. Therapeutically, surgery was used in 307 patients (87.2%) and chemotherapy in 63 cases (17.9%). The one-year mortality rate was 29%., Conclusion: In Burkina Faso rural area, primary digestive cancers occur in young patients with no predominance of sex. Colorectal cancer remains the most common., (Copyright © 2018 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)

Intussusception is a very common condition in pediatrics, while in adults it is rare and accounts for only 10% of intussusceptions and 4% of intestinal occlusions. Colonic lymphoma revealed by intussusception is a very rare disease. We report the case of a 21-year old woman admitted with intestinal subocclusion to the Emergency Department at the Military Hospital Moulay Ismail, Meknes Morocco. Abdominal CT scan showed "sausage-shaped" mass as well as its organic cause in the colon. Surgical resection was the treatment of choice, followed by anatomo-pathological examination of the surgical specimen which showed diffuse large B-cell lymphoma. After surgery, chemotherapy was indicated in order to improve the prognosis and to avoid a possible relapse.

Primary squamous cell carcinoma (SCC) of the colon is an exceptional tumor. Less than 150 cases have been reported in the literature up to the year 2014. In addition to its rarity, it is distinguished by its frequent association with other digestive neoplasias. We report the case of a 54-year old patient with primary SCC of the colon. In the light of this case study, we will discuss the anatomo-clinical and therapeutic features as well as the etiopathogenic assumptions of this unusual entity.

To better understand this cancer, we here report the case of a 43-year old patient diagnosed with localized and isolated primary colonic NK/T-cell lymphoma without associated enteropathy, treated wih 3 cycles of AspaMetDex with a poor response who died during treatment with a clinical picture of acute abdomen. Primary intestinal NK/T-cell lymphoma most commonly affects the young subject with poor prognosis. It is difficult to distinguish between intestinal NK/T-cell lymphoma and inflammatory or infectious intestinal disorders because of its non-specific clinical and endoscopic features. The histopathological and immunohistochemical data as well as the study of DNA allow to adjust the diagnosis and to classify this lymphoma according the European Enteropathy type T-cell lymphoma (ETL)., Competing Interests: Les auteurs ne déclarent aucun conflit d’intérêt.

On the same principle than total mesorectal excision in rectal cancer, the effect of complete mesocolic excision on short and long-term outcomes is actually evaluated for colonic adenocarcinoma. This method, usually performed for left colectomy, offers a surgical specimen of higher quality, with a larger number of lymph nodes harvested. For right colectomy, surgical specifications make it less common complete mesocolic excision and conventional surgery offer comparable outcomes, as regards to postoperative morbidity and mortality rates. No differences are identified between laparoscopic and open surgery. On oncologic outcomes, only two studies report a higher free-disease survival after complete mesocolic excision. Then, there is evidence that complete mesocolic excision offers a higher rate of specimen with extensive lymph node resection, without increased morbidity rate. However, there is limited evidence that it leads to improve long-term oncological outcomes., (Copyright © 2016 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)

Liposarcoma is an extremely rare malignant adipose mesenchymal tumor. World Health Organization classifies liposarcomas into five subtypes: well differentiated, myxoid, pleomorphic, dedifferentiated and mixed. The association between multiple and synchronous location of several subtypes of liposarcomas is exceptional. Only 34 cases have been reported in the literature. We report the case of synchronous association between retroperitoneal dedifferentiated liposarcoma and two small well-differentiated lipoma-like pericolic liposarcomas. Anatomopathological aspects, therapeutic options and prognostic factors of liposarcomas have been reviewed in this study., Competing Interests: Les auteurs ne déclarent aucun conflits d’intérêts.

Introduction: Laparoscopic colectomy is considered with increasing frequency the gold standard treatment for colorectal cancer. Our study aims to show that short-term results and the oncological safety of laparoscopy are at least equivalent to those of laparotomy in the treatment of non-metastatic colic adenocarcinomas. We also highlight the impact of the learning curve on outcomes after laparoscopy in patients with these cancers., Methods: We conducted a retrospective study of all patients undergoing surgery for resectable colic adenocarcinomas over a period of 6 years. The study population was divided into 2 groups based on the surgical procedure used initially. The group "OC" included 35 patients who underwent midline laparotomy and the group "LAC" included 30 patients who underwent laparoscopy. All data were analyzed using SPSS software version 19.0., Results: Our study showed that there was no significant difference in short-term outcomes between the 2 groups, namely intraoperative morbidity, hospital stay, intensive care unit stay as well as postoperative morbidity and mortality. Regarding the long-term outcomes, there was also no significant difference in the incidence of late complications, type of recurrence, overall survival and disease-free survival. Oncological safety based on the limits of resection and the number of lymph nodes removed was not significantly different between the two groups. Operative time was significantly longer in the laparoscopic group (p <0.001). Convertion rate was 33%. It went from 67% in the first 2 years of the study to 13% in the last 2 years. The conversion from laparoscopy to laparotomy had no significant impact neither on early postoperative outcomes nor on overall survival and disease-free survival., Conclusion: Laparoscopy is a surgical procedure resulting in at least equivalent short and long term outcomes as laparotomy. The learning curve representing a "prerequisite" has no negative impact on the outcomes of laparoscopic treatment of non-metastatic colic cancers., Competing Interests: Les auteurs ne déclarent aucun conflit d’intérêts.

Introduction: Bevacizumab is an antibody directed against VEGF-A. It is approved for the treatment of many cancer diseases. Its side effects are currently not well known by physicians., Case Report: A 70-year-old female with metastatic colonic adenocarcinoma was admitted in the intensive care unit because of a coma, four days after having received a combined monthly chemotherapy containing bevacizumab, oxaliplatine, 5 fluorouracil, and folinic acid for the fourth time. On clinical examination, she presented with lower limbs spasticity and hypertension. Etiologic investigations, including cerebral tomodensitometry, cerebrospinal fluid examination, psychotropic drugs urinary testing, and electroencephalogram, were negative. Consciousness improved without any other treatment than nicardipine and urapidil, but the patient was initially confused. Cerebral magnetic resonance imaging showed changes suggestive of posterior reversible encephalopathy syndrome, but also involving frontal lobes. There were additional biological and echocardiographic changes suggestive of cardiac involvement. The patient recovered completely of both cardiac and neurologic manifestations 10 days later., Conclusion: Physicians should be aware of cardiovascular adverse effects of bevacizumab. High blood pressure must be treated to avoid more severe complications. When a posterior reversible encephalopathy syndrome occurs, cardiac involvement should be investigated., (Copyright © 2015 Société nationale française de médecine interne (SNFMI).

Adjuvant treatment has clearly demonstrated its efficacy and safety in resected colon cancer patients, saving thousands of lives every year worldwide. Six months adjuvant chemotherapy combining 5FU and oxaliplatin (FOLFOX or XELOX regimens) is indicated in stage III colon cancer after surgical removal of the primary tumor. The benefit of adjuvant chemotherapy seems less evident in stage II colon cancer, but this treatment should be discussed in patients with "high risk" factors for recurrence. Patient's age is also an important factor for adjuvant treatment decision. The challenge in the future will be to establish predictive and prognostic scores able to offer an even more personalized adjuvant therapeutic approach.

Background: colon cancer is a public health problem worldwide and in Tunisia. The prognosis of patients with unresectable colorectal cancer varies according to the stage. The indication for adjuvant chemotherapy is well established in the colon cancer stage III, while it remains a matter of controversy for stage II. The aim of this work is to identify the epidemiological and anatomoclinical assess therapeutic outcomes in terms of overall survival of patients with high-risk stage II and stage III colon cancer treated with surgery and adjuvant chemotherapy., Methods: DS: It's a retrospective study based on 119 patients with colon adenocarcinoma from 1996 to 2010. This patients suffering from colon cancer classified stage II and III having them all radical surgery and adjuvant chemotherapy., Results: The average age of our patients was 53 years. The surgery was performed in an emergency situation in 53 patients (44%). Stages II and III, respectively, were observed in 47% and 53% of cases. Three regimens of chemotherapy were used: protocol FUFOL (50%), followed by FOLFOX (34%) and the protocol LV5FU2 (16%). Overall survival of patients all stages combined was 73.4% at 5 years. Stage III of the TNM classification (p = 0.03) and the number of cycles of chemotherapy <6 (p=0.02) were a negative prognostic factors influencing overall survival. Patients stage III treated with FOLFOX chemotherapy type had a better survival than those treated with chemotherapy type LV5FU2 or FUFOL with a significant difference (p= 0.05)., Conclusion: Our results are consistent with those in the literature. The prognosis of colon cancer is improving thanks to recent advances that have enabled the integration of new cytogenetic factors in the therapeutic decision.

Thoracic radiotherapy is a usual treatment for lung cancer. Early-stages may be treated in stereotactic mode while locally advanced stages are usually treated with conventional radiotherapy mode. Pulmonary function tests show that thoracic irradiation has no impact on lung volume such as forced expiratory volume in one second (FEV1) or forced vital capacity (FCV). However, some studies found that CO (carbon monoxide) diffusing capacity (TLCO) may be altered under thoracic radiotherapy. DLCO alteration is usually symptomatic of either a lesion in the alveolar membrane or a pulmonary capillary alteration. Pulmonary diffusion may be also appreciated by the NO (azote monoxide) diffusion capacity. Moreover, using a double measurement of NO and CO diffusing capacities permit to assess which lung compartment (capillary or membrane) is affected. CONORT is an observational prospective monocentric study, aiming to assess the CO and NO diffusing capacity (as well as other pulmonary function tests) during thoracic radiotherapy. Inclusion criteria are patients with lung cancer, treated by thoracic radiotherapy (conformational or stereotactic), who signed consent. Pulmonary function tests are performed before, during, at the end and six weeks and six months after thoracic irradiation. To estimate a difference of 15% in diffusing capacity test, we have to include 112 patients with a 90% power and a 5% alpha risk. Four months after beginning, 36 patients were included. Preliminary data will be presented at the SFRO meeting., (Copyright © 2014 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS. All rights reserved.)

Secondary localization to vagina had a severe prognosis, suggesting a disseminated metatastic disease. We report the case of prevalent vaginal metastasis of adenocarcinoma of the transverse colon. A 65 years old patient has consulted for vaginal mass. After delayed diagnosis, she presented with disseminated metastatic disease with peritoneal carcinomatosis. After neoadjuvant chemotherapy, the following treatment consisted of complete cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy and vaginal adjuvant radiotherapy. No recurrence occurred after one year. Vaginal metastasis of colon cancer are rare. The dark prognosis might justify a systematic gynecological examination of women presenting colorectal neoplasy., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)

Sentinel lymph node (SLN) is a concept but also a technical possibility that can be studied and applied to almost all organs with cancer. For colorectal cancer surgery, some possibilities of using the SLN are possible, other implausible and some completely new especially aware of possible analysis of SLN by a molecular biology technique. The orientation of dissection or "lymph road mapping" can be designed for this case or the surgeon may want to limit his actions, particularly in patients with a history of colonic surgical resection, to keep the digestive function in maintaining vascular axes considered not involved in the metastatic process. The use of the single analysis of SLN to determine the positive or negative status of the cleaning has failed because of the frequency of false negatives in part to the size of colic advanced cancers at diagnosis. The use of "ultra-stading" by multiple section or exhaustion of the block, can lead to reconsider a stage N0 to N1 as a point, if the analysis technique remains in HES. Unlike the "ultra-stading" by RT- PCR or immunohistochemistry was even more discussed and seems not equivalent in terms of prognosis and therefore no giving formally justification for adjuvant therapy. Currently, a new technique for molecular biology, named "OSNA", allows an analysis of all the SLN in less than 45 minutes. It is therefore possible to obtain during surgery analysis of a node with the same level of information than traditional analysis using HES. If this node is positive and if the strategy in case of positive lymph nodes was determined prior for this patient, it is possible to anticipate this strategy and place after colectomy during the same anesthesia, venous access quickly to start postoperative chemotherapy. This new technique for analyzing lymph applied to the SLN opens a new potential application of this concept in digestive oncology.

We report the case of a 63 year old man with laryngeal metastasis of a colonic adenocarcinoma recurrent after partial cordectomy by CO2 Laser microlaryngoscopy. This patient was followed for this condition between 2009 and 2010. The rarity of metastatic laryngeal metastases, particularly when the primary tumor is colic, justifies this presentation.

Individual screening of patients with personal or family history of colon cancer or polyps, or patients with an inflammatory condition of the digestive tract, combined with the generalization of mass screening using Hemoccult, have modified the way colon cancer is diagnosed. The optimization of colon surgery, together with adjuvant chemotherapy, has improved the 5- and 10-year survival. The five-year survival rate is now comprised between 90 percent in patients with stage-I colon cancer, and 65-70 percent in patients with stage-III colon cancer. More than half patients suffer from stage-II (T3-T4 N0) or stage-III (TxN+) cancer, and 30 to 40 percent of these patients experience cancer recurrence without adjuvant therapy within 5 years following surgery. In patients with surgically-resected colon cancer, these recurrences are mostly metastatic (liver, lungs, peritoneum), local recurrences remain uncommon. Metastases are secondary to microscopic tumor foci disseminated away from the primary tumor, non detectable before and during surgery. An adjuvant therapy combining oxaliplatin and fluoropyrimidine is clearly indicated in patients with stage-III colon tumor (20-percent improvement of survival without recurrence), and can be considered in stage-III patients. This treatment is not indicated in patients with stage-I tumor.

Small-cell endocrine carcinoma is a particularly aggressive form of endocrine carcinoma characterized by its rapid and early metastatic dissemination. We report a 59-year-old man who presented with abdominal pain as the initial manifestation of a colonic small-cell endocrine carcinoma with early liver metastases and poor prognosis. Poorly differentiated endocrine carcinomas are rare tumours that generally occur in the lung, but are exceptionally localized in other sites. Generally, these tumours have an aggressive behaviour with early metastatic spread, and curative surgical resection is often impossible. Despite aggressive chemotherapy, these extended tumours have an unfavourable outcome., (Copyright 2010 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

Introduction: Fundamental research identified new therapy targets implicated in tumor proliferation and angiogenesis which lead to the development of several targeted therapies. Currently, three drugs are used in the treatment of advanced colorectal cancer, cetuximab and panitumumab, two anti epidermal growth factor receptor, and bevacizumab, an anti vascular endothelial growth factor., Patients and Methods: We evaluated a treatment with oxaliplatin-based chemotherapy (Folfox7 regimen) and bevacizumab in patients with locally advanced and/or metastatic colorectal cancer. Objectives of the study are the evaluation of the efficacy, toxicity, progression free survival, overall survival and tumor cell expression of the vascular endothelial growth factor by immunochemistry., Results: 47 patients are included in the study during the period between April 2005 and June 2007; 28 men and 19 women. After six cycles of treatment, we achieved 67.3% of objectives responses and 76% of tumor control. The median progression free survival evaluated was 12 months (9.3-14.6 months) and median overall survival 18 months (9-26.9 months). The immunochemistry study of 46 tumours of the study achieved the following results: 13% (0), 17.4% (1+), 23.9% (2+) and 45.7% (3+). A correlation between the vascular endothelial growth factor expression, therapeutic responses and survival has been demonstrated but the difference was not significant in term of survival. Both chemotherapy toxicity and bevacizumab related toxicity are acceptable in our study., Conclusion: The fact that vascular endothelial growth factor expression is common in more than 80% of colorectal cancers, lead to recommend the systematic use of bevacizumab with chemotherapy in the treatment of advanced colorectal cancer.

We report the case of a carcinoid tumor with suspicion of recurrence on biology. Scintigraphic explorations of the whole body had a major role in diagnostic of this recurrence. OctreoScan((R)) showed an abdominal uptake corresponding to a mesenteric lymph node. PET with (18)F-DOPA also showed a liver uptake corresponding to liver metastases.
