[Abdominal surgery: what's new in 2023]. / Chirurgie viscérale: ce qui a changé en 2023.

In 2023, robotic surgery has witnessed an expansion in the number of surgical procedures and in the number of platforms on the market. We illustrate the phenomenon, by exploring parietal, œso-gastric and liver robotic surgery. Surgical innovation aligns with advancements in oncology. Immunotherapy now enables "watch and wait" strategies for patients with colorectal cancer, and decreases recurrence rate and improves survival after liver surgery for hepatocellular carcinoma and œso-gastric surgery. The multidisciplinary field of obesity management has seen the development of new medications, diversifying the treatment options, while surgery continues to deliver the best weight-loss outcomes.

En 2023, la chirurgie robotique a poursuivi son expansion avec une augmentation du nombre d'interventions et la mise sur le marché de nouvelles plateformes. Ce phénomène est illustré dans cet article par la description des chirurgies robotique pariétale, œsogastrique et hépatique. L'innovation en chirurgie accompagne aussi celle de l'oncologie. L'immunothérapie permet maintenant une stratégie « watch and wait ¼ chez les patients avec un cancer colorectal, diminue le risque de récidive et améliore la survie après chirurgie hépatique pour un carcinome hépatocellulaire et chirurgie œsogastrique. Le domaine multidisciplinaire de la prise en charge de l'obésité a aussi vu l'arrivée de nouveaux traitements médicamenteux, qui viennent diversifier les options thérapeutiques, où la chirurgie continue d'apporter les meilleurs résultats en termes de perte de poids.

[Treatment of localized rectal cancer in 2024]. / Prise en charge du cancer du rectum localisé en 2024.

The management of localized rectal cancer has evolved significantly over the last two years. On one hand, intensification of treatments (radio-chemotherapy, chemotherapy, then surgery) for the most advanced tumors has shown an improvement in clinical results compared to less intense regiments. On the other hand, the possibility, as for prostate cancers, of opting for active surveillance without surgery in patients presenting a complete clinical response after a treatment phase, is now accepted. More recently, the Swiss recommendations for the surveillance of rectal cancer have been modified and now differ from those of colon cancers, by incorporating pelvic MRI and rectoscopy in addition, as well as special guidelines for tumors under active surveillance.

La prise en charge du cancer du rectum localisé a beaucoup évolué ces deux dernières années. D'un côté, l'intensification des traitements (radio-chimiothérapie, chimiothérapie, puis chirurgie) pour les tumeurs les plus avancées a montré une amélioration des résultats cliniques par rapport aux traitements moins intenses. De l'autre côté, la possibilité, comme pour les cancers de la prostate, d'opter pour une surveillance active sans chirurgie chez les patients présentant une réponse clinique complète après une phase de traitement est aujourd'hui acceptée. Plus récemment, les recommandations suisses pour la surveillance du cancer du rectum ont été modifiées et se différencient maintenant de celles des cancers du côlon, en incorporant IRM pelvienne et rectoscopie en sus, de même qu'un suivi spécial pour les tumeurs en surveillance active.

[Colorectal cancer: technological revolution]. / Cancer colorectal : révolution technologique.

Colorectal cancer represents 4500 incidental cases in Switzerland per year, with an incidence increasing among the youngest patients. Technological innovation guides the management of colorectal cancer. Artificial intelligence in endoscopy optimizes the detection of small colonic lesions. Submucosal dissection allows treating extensive lesions at an early stage of the disease. The improvement of surgical techniques, notably robotic surgery, allows limiting complications and optimizing organ preservation. Molecular tools are leading to the development of promising targeted therapies for localized or advanced disease. The development of reference centers tends to bring together this expertise.

Le cancer colorectal représente 4500 nouveaux cas par an en Suisse. Son incidence chez les sujets de plus de 50 ans semble se stabiliser, mais chez les plus jeunes elle est en augmentation. La révolution technologique guide sa prise en charge. L'intelligence artificielle en endoscopie optimise la détection de petites lésions coliques. La dissection sous-muqueuse permet de traiter des lésions parfois étendues à un stade précoce de la maladie. L'amélioration des techniques chirurgicales, notamment par robot, vise à limiter les complications et à optimiser la conservation d'organes. Les outils moléculaires aboutissent au développement de thérapies ciblées prometteuses pour les maladies localisées ou celles avancées. Le développement des centres de référence tend à rassembler cette expertise.

Study protocol of a phase II study to evaluate safety and efficacy of neo-adjuvant pembrolizumab and radiotherapy in localized rectal cancer.

BACKGROUND: Reshaping the tumor microenvironment by novel immunotherapies represents a key strategy to improve cancer treatment. Nevertheless, responsiveness to these treatments is often correlated with the extent of T cell infiltration at the tumor site. Remarkably, microsatellite stable rectal cancer is characterized by poor T cell infiltration and, therefore, does not respond to immune checkpoint blockade. To date, the only available curative option for these patients relies on extensive surgery. With the aim to broaden the application of promising immunotherapies, it is necessary to develop alternative approaches to promote T cell infiltration into the tumor microenvironment of these tumors. In this regard, recent evidence shows that radiotherapy has profound immunostimulatory effects, hinting at the possibility of combining it with immunotherapy. The combination of long-course chemoradiotherapy and immune checkpoint inhibition was recently shown to be safe and yielded promising results in rectal cancer, however short-course radiotherapy and immune checkpoint inhibition have never been tested in these tumors. METHODS: Our clinical trial investigates the clinical and biological impact of combining pembrolizumab with short-course radiotherapy in the neo-adjuvant treatment of localized rectal cancer. This phase II non-randomized study will recruit 25 patients who will receive short-course preoperative radiotherapy (5 Gy × 5 days) and four injections of pembrolizumab starting on the same day and on weeks 4, 7 and 10. Radical surgery will be performed three weeks after the last pembrolizumab injection. Our clinical trial includes an extensive translational research program involving the transcriptomic and proteomic analysis of tumor and blood samples throughout the course of the treatment. DISCUSSION: Our study is the first clinical trial to combine short-course radiotherapy and immune checkpoint inhibition in rectal cancer, which could potentially result in a major breakthrough in the treatment of this cancer. Additionally, the translational research program will offer insights into immunological changes within the tumor and blood and their correlation with patient outcome. Taken together, our work will help optimizing future treatment combinations and, possibly, better selecting patients. TRIAL REGISTRATION: This study was registered with www. CLINICALTRIAL: gov : NCT04109755 . Registration date: June, 2020.

Where Are We Now and Where Might We Be Headed in Understanding and Managing Brain Metastases in Colorectal Cancer Patients?

OPINION STATEMENT: Compared to liver and lung metastases, brain metastases (BMs) from colorectal cancer (CRC) are rare and remain poorly investigated despite the anticipated rise in their incidence. CRC patients bearing BM have a dismal prognosis with a median survival of 3-6 months, significantly lower than that of patients with BM from other primary tumors, and of those with metastatic CRC manifesting extracranially. While liver and lung metastases from CRC have more codified treatment strategies, there is no consensus regarding the treatment of BM in CRC, and their management follows the approaches of BM from other solid tumors. Therapeutic strategies are driven by the number and localisation of the lesion, consisting in local treatments such as surgery, stereotactic radiosurgery, or whole-brain radiotherapy. Novel treatment modalities are slowly finding their way into this shy unconsented armatorium including immunotherapy, monoclonal antibodies, tyrosine kinase inhibitors, or a combination of those, among others.This article reviews the pioneering strategies aiming at understanding, diagnosing, and managing this disease, and discusses future directions, challenges, and potential innovations in each of these domains. HIGHLIGHTS: • With the increasing survival in CRC, brain and other rare/late-onset metastases are rising. • Distal colon/rectal primary location, long-standing progressive lung metastases, and longer survival are risk factors for BM development in CRC. • Late diagnosis and lack of consensus treatment strategies make BM-CRC diagnosis very dismal. • Liquid biopsies using circulating tumor cells might offer excellent opportunities in the early diagnosis of BM-CRC and the search for therapeutic options. • Multi-modality treatment including surgical metastatic resection, postoperative SRS with/without WBRT, and chemotherapy is the best current treatment option. • Recent mid-sized clinical trials, case reports, and preclinical models show the potential of unconventional therapeutic approaches as monoclonal antibodies, targeted therapies, and immunotherapy.

[Intraperitoneal therapy for carcinomatosis in ovarian cancer: proposed treatment algorithm]. / Traitements intrapéritonéaux de la carcinose ovarienne : proposition d'algorithmes décisionnels.

Ovarian cancer is the first cause of death by gynecological cancer. Most of the patients are diagnosed with peritoneal carcinomatosis that represents a therapeutic challenge. Its management implies maximal cytoreductive surgery with survival benefit. Over the last three decades, several strategies of intra-peritoneal chemotherapy have been investigated. This includes intra-peritoneal adjuvant chemotherapy that is used mainly in North America, hyperthermic intraperitoneal chemotherapy (HIPEC) and more recently pressurized intraperitoneal aerosol chemotherapy (PIPAC). In the current article, we review the evidence in favor of each therapeutic approach, and we propose treatment algorithms depending on the clinical situation of ovarian cancer patients: upfront, platinum-sensitive and platinum-resistant relapse.

Le cancer de l'ovaire est la première cause de décès par cancer gynécologique. La plupart des patientes sont diagnostiquées au stade de carcinose péritonéale qui représente un défi thérapeutique. Sa prise en charge chirurgicale implique une cytoréduction maximaliste. Au cours des 30 dernières années, plusieurs stratégies de chimiothérapie intrapéritonéale ont été testées afin d'améliorer le contrôle de la carcinose péritonéale. Il s'agit des chimiothérapies intrapéritonéale adjuvante utilisée surtout en Amérique du Nord, hyperthermique intrapéritonéale (CHIP) et intrapéritonéale pressurisée en aérosols (PIPAC). Dans cet article, nous reprenons les données de la littérature sur chacune de ces trois approches thérapeutiques et proposons des algorithmes décisionnels selon la situation clinique des patientes traitées pour un cancer de l'ovaire : au diagnostic, récidive platine-sensible et platine-résistante.

Highlights from ASCO-GI 2021 from EORTC Gastrointestinal tract cancer group.

Last year the field of immunotherapy was finally introduced to GI oncology, with several changes in clinical practice such as advanced hepatocellular carcinoma or metastatic colorectal MSI-H. At the virtual ASCO-GI symposium 2021, several large trial results have been reported, some leading to a change of practice. Furthermore, during ASCO-GI 2021, results from early phase trials have been presented, some with potential important implications for future treatments. We provide here an overview of these important results and their integration into routine clinical practice.

[Place of immunotherapy in digestive oncology]. / Place de l'immunothérapie en oncologie digestive.

Digestive tumors account for a quarter of all new cancer cases diagnosed worldwide and are responsible for a third of global cancer-related deaths. Immunotherapy with immune checkpoint inhibitors has recently shown its effectiveness in the therapeutic arsenal of these tumors, mainly in the advanced stages. This article summarizes the current indications and the future direction of immunotherapy in patients with digestive malignancies.

Les tumeurs digestives représentent un quart de tous les nouveaux cas de cancers diagnostiqués dans le monde et sont responsables d'un tiers des décès mondiaux liés au cancer. L'immunothérapie par inhibiteurs de points de contrôle immunitaire (Immune Checkpoint Inhibitors) a récemment démontré son efficacité dans l'arsenal thérapeutique de ces tumeurs, principalement aux stades avancés. Cet article résume les indications actuelles et l'orientation future de l'immunothérapie chez les patients atteints de tumeurs malignes digestives.

Reliability of liquid biopsy analysis: an inter-laboratory comparison of circulating tumor DNA extraction and sequencing with different platforms.

Liquid biopsy, the analysis of circulating tumor DNA (ctDNA), is a promising tool in oncology, especially in personalized medicine. Although its main applications currently focus on selection and adjustment of therapy, ctDNA may also be used to monitor residual disease, establish prognosis, detect relapses, and possibly screen at-risk individuals. CtDNA represents a small and variable proportion of circulating cell-free DNA (ccfDNA) which is itself present at a low concentration in normal individuals and so analyzing ctDNA is technically challenging. Various commercial systems have recently appeared on the market, but it remains difficult for practitioners to compare their performance and to determine whether they yield comparable results. As a first step toward establishing national guidelines for ctDNA analyses, four laboratories in Switzerland joined a comparative exercise to assess ccfDNA extraction and ctDNA analysis by sequencing. Extraction was performed using six distinct methods and yielded ccfDNA of equally high quality, suitable for sequencing. Sequencing of synthetic samples containing predefined amounts of eight mutations was performed on three different systems, with similar results. In all four laboratories, mutations were easily identified down to 1% allele frequency, whereas detection at 0.1% proved challenging. Linearity was excellent in all cases and while molecular yield was superior with one system this did not impact on sensitivity. This study also led to several additional conclusions: First, national guidelines should concentrate on principles of good laboratory practice rather than recommend a particular system. Second, it is essential that laboratories thoroughly validate every aspect of extraction and sequencing, in particular with respect to initial amount of DNA and average sequencing depth. Finally, as software proved critical for mutation detection, laboratories should validate the performance of variant callers and underlying algorithms with respect to various types of mutations.

[Esophageal and esophago-gastric junction cancer†: management and multimodal treatment]. / Cancer de l'œsophage et de la jonction œsogastrique†: prise en charge et traitement multidisciplinaire.

Esophageal cancer remains an oncological burden with a low survival rate. Multidisciplinary management is essential to offer an adjusted treatment to the patient general condition and the tumor stage. New minimally invasive surgical treatments help to reduce the surgical trauma and improve post-operative patient recovery. Oncological treatments have also evolved and definitive treatment by radio-chemotherapy can be proposed in specific cases.

Le cancer de l'œsophage reste un fardeau oncologique avec un taux de survie bas. Une prise en charge multidisciplinaire est primordiale afin d'offrir un traitement adapté à l'état général du patient et au stade de la tumeur. De nouvelles prises en charge minimalement invasives chirurgicales permettent de diminuer le traumatisme d'une chirurgie majeure et améliorent la récupération des patients en postopératoire. Les traitements oncologiques ont également évolué et un traitement définitif par radiochimiothérapie peut être proposé dans des cas précis.

[Doctor, is it reasonable for me to pursue a physical activity in my condition?] / Docteur, une activité physique dans mon état est-ce bien raisonnable ?

The prevalence of cancer is increasing, with an estimated number of new cases of 21.6 million worldwide by 2030. Progress in cancer therapies has turned it into a chronic disease. Physical exercise is essential both for the general population and for oncology patients. Practicing exercise reduces the risk of developing certain cancer types and, in oncologic patients, it can reduce symptoms secondary to the disease and to treatment as well as decrease the risk of relapsing. Encouraging adapted physical exercise to every oncologic patient is therefore essential (or crucial). It is recommended to practice regular physical activity equivalent to 150 minutes of moderate intensity or 75 minutes of high intensity activity per week.

La prévalence du cancer est en augmentation avec 21,6 millions de nouveaux cas dans le monde d'ici 2030. L'évolution des traitements permet de faire du cancer une maladie chronique. L'activité physique est une question essentielle à la fois au sein de la population générale, mais également pour les patients oncologiques. La pratique d'une activité physique permet de diminuer le risque de survenue de certains cancers mais également, pour les patients oncologiques, de réduire les symptômes liés à la maladie et aux traitements et le risque de récidive. Favoriser une activité physique adaptée pour chaque patient oncologique est donc fondamental. Les recommandations préconisent une activité physique régulière correspondant à 150 minutes d'activité d'intensité modérée ou 75 minutes d'activité d'intensité élevée par semaine.

[Role of echocardiography before, during and after anticancer treatment]. / Rôle de l'échocardiographie avant, pendant et après un traitement anticancéreux.

Cardiologists increasingly must face not only the cardiotoxicity of certain cancer therapies, but also the burden of morbidity related to previous chemotherapy in cancer survivors. Due to the formidable effectiveness of novel oncology treatments, cancer patients are treated with drugs with limited experience of their use and systemic toxicity profile, notably their cardiotoxic effects. Echocardiography is recognized as a must in the evaluation of patients before, during and after their potentially cardiotoxic treatment. We discuss how certain echocardiographic parameters, including the evaluation of left ventricular ejection fraction but also other factors that can help guide the management of cancer patients throughout their treatment and beyond.

Avec l'amélioration générale du pronostic des cancers, les cardiologues sont de plus en plus confrontés non seulement à la cardiotoxicité immédiate de certaines thérapies oncologiques, mais également à la survenue de complications tardives chez les patients en rémission. Devant l'efficacité redoutable de certaines nouvelles thérapies, les patients bénéficient souvent précocement de molécules pour lesquelles nous manquons de recul quant à leur toxicité potentielle systémique et cardiaque. L'échocardiographie est actuellement reconnue comme un moyen incontournable dans l'évaluation avant, pendant et après un traitement potentiellement cardiotoxique. Nous discutons dans cet article des paramètres échocardiographiques, incluant l'évaluation de la fraction d'éjection du ventricule gauche, mais aussi d'autres facteurs qui peuvent aider à orienter la prise en charge des patients oncologiques tout au long de leur traitement.

Circulating tumoral DNA: Preanalytical validation and quality control in a diagnostic laboratory.

We present the results of our technical validation process in establishing the analysis of circulating tumor DNA (ctDNA) as a diagnostic tool. Like most cells in our body, tumor cells shed DNA in the blood flow. Analysis of ctDNA mutational content can provide invaluable information on the genetic makeup of a tumor, and assist oncologists in deciding on therapy, or in following residual disease. However, low absolute amounts of circulating DNA and low tumor fraction constitute formidable analytical challenges. A key step is to avoid contamination with genomic DNA from cell lysis. Several brands of specialized blood collection tubes are available to prevent leukocyte lysis. We show that they are not equally efficient, depending on storage temperature and time before plasma preparation. We report our analysis of preanalytical factors pertaining to ctDNA analysis (tubes, transportation time, temperature) and our conclusions in terms of instructions to prescribing physicians. We also stress the importance of proper DNA quality control and compare several methods, including a differential amplicon length PCR technique which allows determination of multiple QC parameters from minimal amounts of DNA. Altogether, these data provide useful practical information to diagnostic laboratories wishing to implement the assay of ctDNA in clinical practice.

[Hepatocellular carcinoma : updated management guidelines]. / Carcinome hépatocellulaire : nouvelles recommandations de prise en charge.

Here we summarize new European recommendations for the management of hepatocellular carcinoma (HCC), the main form of cancer affecting the liver, usually occurring in the context of underlying liver disease. Screening for HCC by bi-annual ultrasound is indicated in most cirrhotic and non-cirrhotic patients. The detection of a new hepatic lesion should raise the suspicion of HCC, especially in cirrhotic subjects. The diagnostic and therapeutic management of HCC is complex and requires a multidisciplinary approach.

Nous résumons ici des nouvelles recommandations européennes de prise en charge du carcinome hépatocellulaire (CHC), la forme principale de cancer du foie, survenant généralement sur un terrain de maladie hépatique sous-jacente et dont l'incidence globale augmente. Le dépistage du CHC, par une échographie biannuelle, est indiqué chez la plupart des patients cirrhotiques et certains sujets non cirrhotiques. La mise en évidence d'une nouvelle lésion hépatique doit faire suspecter le développement d'un CHC, en particulier sur un terrain de cirrhose. La prise en charge diagnostique et thérapeutique du CHC est complexe et nécessite une approche multidisciplinaire.

[VIPoma : a rare etiology of diarrhea with hypokalemia]. / VIPome : étiologie rare d'une diarrhée hypokaliémiante.

VIPoma or Verner Morrison syndrome is a very rare disease with an incidence rate of 1 case per 10 000 000 person-years. It is a neuroendocrine tumor issue from ß-pancreatic islets leading to profuse diarrhea, hypokalemia and gastric achlorydria due to secretion of vasoactive intestinal polypeptide (VIP) hormone. Diagnosis is based on histology of tumor and the dosage of VIP in a blood sample. Somatostatin analog is a simple and efficient treatment for diarrhea. Curative treatment with surgery could be proposed for a localized disease. For disseminated disease, there are different treatments and a multimodal assessment that should be discussed in a multidisciplinary team might be curative.

Le VIPome ou syndrome de Verner Morrison est une maladie très rare, avec une incidence annuelle estimée à 1/10 000 000 habitants. Il s'agit d'une tumeur neuroendocrine issue des îlots ß pancréatiques qui sécrète une hormone appelée vasoactive intestinal polypeptide (VIP), à l'origine d'une achlorhydrie gastrique et de diarrhées profuses entraînant une hypokaliémie. Le diagnostic est posé à partir d'une analyse anatomopathologique de la tumeur et du dosage du VIP sanguin. Le traitement symptomatique par les analogues de la somatostatine est efficace sur la diarrhée. Un traitement curatif par la chirurgie peut être proposé pour une maladie tumorale localisée. Pour les maladies disséminées, différentes modalités thérapeutiques existent et dans certains cas une approche multimodale discutée dans un colloque spécialisé peut être curative.

[Appendix tumours and their management]. / Les tumeurs de l'appendice et leur prise en charge.

An appendix tumour is found every 100 appendectomies. It can also be incidental discovery during a routine radiological examination and presents as a mucocele of the appendix. Appendix tumours are of varied histological type, and include mainly neuroendocrine tumours as well as epithelial tumours. The latter, when they secrete mucin, can give rise to peritoneal pseudomyxoma, a particular form of carcinosis harbouring serious complications. The management of appendix tumours responds to specific recommendations and, in advanced cases, requires the expertise of a university centre specialized in digestive oncology. The role of the primary care practitioner lies in the diagnosis and referral of patients with appendix tumours.

Une tumeur appendiculaire est retrouvée pour 100 appendicectomies. Elle peut aussi être découverte fortuitement lors d'un examen radiologique de routine et se présenter sous la forme d'un mucocèle de l'appendice. Les tumeurs appendiculaires sont de types histologiques variés et comprennent majoritairement les tumeurs neuroendocrines ainsi que les tumeurs épithéliales. Ces dernières, lorsqu'elles secrètent de la mucine, peuvent se présenter sous la forme d'un pseudomyxome péritonéal, une carcinose péritonéale particulière grevée d'importantes complications. La prise en charge des tumeurs appendiculaires répond à des recommandations particulières et, dans les cas avancés, nécessite l'expertise d'un centre universitaire spécialisé en oncologie digestive. Le rôle du médecin de premier recours réside dans le diagnostic et l'orientation des patients atteints d'une tumeur appendiculaire.

[Can the management and pronostic of pancreatic adenocarcinoma be improved ?] / Adénocarcinome du pancréas : peut-on améliorer la prise en charge et le pronostic ?

Pancreatic cancer is the 10th leading cause of death worldwide. It is a very lethal and aggressive tumor, with a 5-year overall survival rate under 5 % for confirmed ductal adenocarcinoma. Even though many genes have been identified as possible treatment targets, surgery remains the only curative treatment. Imaging is essential to the initial workup and is mostly based on CT-scan and MRI studies. Resectability is based on the absence of distant metastases and arterial vasculature infiltration. 3D imaging reconstruction could add precision to the surgical evaluation. Many phase II non randomized studies have shown that neo-adjuvant chemotherapy had a positive effect on pancreatic cancer. Nevertheless this approach is only reserved for cases with locally advanced tumors.

Le cancer du pancréas est la 10e cause de décès au monde. C'est une tumeur très agressive avec un taux de survie global à cinq ans en dessous de 5 % pour les adénocarcinomes canalaires confirmés. Bien que plusieurs gènes aient pu être identifiés comme d'éventuels cibles de traitements, la chirurgie reste l'unique traitement curatif pour cette maladie. Dans le bilan initial, l'imagerie tient une place prépondérante et est surtout basée sur le CT-scan et l'IRM. Les critères de résécabilité chirurgicale sont basés sur l'absence de métastases à distance et d'infiltration des vaisseaux artériels. La reconstruction 3D des images semble apporter plus de précision afin de déterminer la stratégie chirurgicale. Plusieurs études prospectives de phase II non randomisées ont déjà montré que les traitements néoadjuvants de chimiothérapie auraient un effet bénéfique sur les cancers du pancréas. Toutefois, cette approche est pour l'instant réservée uniquement aux cas localement avancés.

Nephrotic Syndrome in Small Cell Lung Cancer and Induction of C-Mip in Podocytes.

Paraneoplastic nephrotic syndrome is often a complication in patients with cancer, and various histologic lesions have been described in the kidney. We report the case of a 76-year-old woman who presented with a podocytopathy that was found to be associated with a small cell lung carcinoma (SCLC). One cycle of carboplatin-etoposide combination therapy led to resolution of nephrotic syndrome and remission of the lung carcinoma. C-Maf-inducing protein (C-Mip) was overexpressed in both podocytes and cancer cells, but was not found in control kidney and lung tissue samples. C-Mip also was absent in SCLC cells from 30 patients without nephrotic syndrome. Exposing cultured podocytes to a sample of our patient's serum that was collected prior to chemotherapy led to disorganization of the podocyte cytoskeleton and induction of C-Mip expression, which was not observed with control serum or our patient's serum sampled after chemotherapy. These observations suggest that C-Mip may play an important role in SCLC-related podocytopathy and that a circulating factor likely induces its expression in the kidney.

Chemotherapy-induced Takotsubo cardiomyopathy, a case report and review of the literature.

BACKGROUND: Several chemotherapy molecules, monoclonal antibodies and tyrosine kinase inhibitors, have been linked to Takotsubo cardiomyopathy (TC). CASE PRESENTATION: In this article, we describe the case of a 45-year-old woman who developed TC after receiving an intra-arterial and intra-venous polychemotherapy for locally advanced epidermoid carcinoma of the anal canal. This is the first described case of TC associated with intra-arterial chemotherapy. CONCLUSIONS: A review of the literature points to 5-fluorouracil as the most common molecule associated with TC and highlights the potential risk associated with rechallenging patient with the same drug.

[Multidisciplinary management of localized rectal cancer]. / Prise en charge multidisciplinaire du cancer localisé du rectum.

Rectal cancer remains a frequent pathology, with a good prognosis, according to a proper management. During the last decades, we have been confronted with important improvements, notably regarding the diagnosis and the treatment. In the era of highly specialized medicine, it is clear that the management must be multidisciplinary, incorporating not only the surgeon, the oncologist and the radiation oncologist, but also the radiologist, the gastroenterologist, and the pathologist. We aim to review the recent concepts and the future developments in the management of rectal cancer.

Le cancer du rectum demeure une pathologie fréquente, dont le pronostic est heureusement bon. Ces dernières décennies, nous avons été confrontés à plusieurs avancées importantes, que ce soit au niveau du diagnostic ou du traitement. Sa prise en charge fait partie intégrante de la médecine hautement spécialisée, et il est devenu clair que l'approche se doit d'être multidisciplinaire, incorporant aussi bien le chirurgien, l'oncologue et le radio-oncologue, que le radiologue, le gastroentérologue et le pathologue. Dans cet article, les concepts récents ainsi que les perspectives futures sont analysés.
