An interventional pulmonologist possesses expertise in minimally invasive diagnostic and therapeutic procedures involving the airways, lungs and pleura. A malignant pleural effusion (MPE), which occurs in 20% of cancer patients, can be a daunting diagnostic challenge insofar as the pleural cavity is a closed cavity. In these patients, treatment may consequently be delayed before a precise diagnosis can be given. In the meantime, an interventional pulmonologist is called upon to carry out a wide range of examinations in order to establish the etiological diagnosis and to treat the symptoms of an MPE patient. Classical medical thoracoscopy, also called "pleuroscopy", is the reference method in MPE diagnosis because it allows visualization of the pleural cavity, pleural biopsy under direct visual control, providing excellent diagnostic yield. Over the past decade, new diagnostic methods have emerged, such as ultrasound-guided biopsy, as well as different interventions, such as indwelling pleural catheters, aimed at improving the quality of life of MPE patients, for whom therapeutic options are limited. The objective of this review of the literature is to point out the role of the interventional pulmonologist in the management of MPE by detailing the various diagnostic and therapeutic methods he possesses at the present time.

Androgen-deprivation therapy (ADT), either bilateral orchiectomy or treatment with a gonadotropin-releasing hormone analogue agonist or antagonist, is the mainstay of treatment for advanced prostate cancer. In the metastatic setting, although ADT is initially effective, castration-resistant disease eventually develops in almost all men with prostate cancer. Since 2015, the addition of docetaxel, abiraterone, enzalutamide, apalutamide or darolutamide with docetaxel to ADT has been shown to improve overall survival (OS) of patients starting ADT for metastatic disease. Castration resistance occurs when disease progresses despite testosterone in the castrate range most commonly with or, more rarely, without detectable metastases. The addition of next-generation antiandrogens to ADT has been shown to improve OS in patients with high-risk nonmetastatic castration-resistant prostate cancer (nmCRPC) identified by a PSA doubling time (DT) ? 10 months. Apalutamide is a nonsteroidal antiandrogen agent that binds directly to the ligand-binding domain of the androgen receptor without agonist activity. When added to ADT apalutamide has been shown to improve OS by 35 % in patients starting ADT for metastatic prostate cancer both in patients with upfront metastatic disease or after previous treatment with curative intent. Similarly apalutamide has been shown to provide a 14-month OS improvement in patients with nmCRPC and short PSA DT. These OS benefits were obtained at no cost in terms of quality of life. Apalutamide is given orally once a day and is well tolerated. The most common side effects are fatigue, rash, hypertension and hot flushes. Potential interactions with concomitant medication should be taken into account.

Nipple-areolar complex anomalies may be secondary to many etiologies from simple anatomic variations to malignant processes as Paget disease or invasive breast cancer, passing through benign locally aggressive processes as erosive adenomatosis of the nipple. Differential diagnosis is not always simple. If clinical exam and standard radiological checkup can't confirm the benignity of the lesion, a biopsy specimen will be obtained to allow an anatomopathological examination. A precise diagnosis can then be made leading to optimal management. This paper describes how to explore nipple-areolar complex anomalies through an uncommon clinical case associating independently an invasive retro-areolar cancer and a dermatological disease of the areola mimicking a Paget disease.

Mucinous nevus is an exceptional entity and presents as flesh-colored to brownish papules or plaques, coalescing to form a pigmentary or verrucous lesion with either a blaschkoid, linear, grouped or zosteriform disposition. It usually appears at birth or during early childhood, but late onset has also been described. Mucinous nevus does not require additional work-up as no internal pathologies have been described. Abstention of any therapeutic intervention is usually preferred.

The objective of this research was to study the evolution of the mastectomy rate in patients with breast cancer between 1998 and 2015, based on population data from the Côte d'Or breast cancer registry of the FRANCIM network ("France cancer incidence and mortality").

To determine the elastographic characteristics of idiopathic granulomatous mastitis compared to breast carcinoma.

To assess the morbidity specific of extended pelvic lymphadenectomy during robot-assisted laparoscopic radical prostatectomy in a 8 year retrospective study.

Context Bronchial cancer in a person under 30 years of age is quite rare. It generally occurs after 40 years of age following heavy smoking intoxication. We report a clinical case illustrating the early onset of a small cell lung carcinoma in young heavy smoker. CASE REPORT: A 30-year-old patient, current smoker for about 10 years (15 packs/year), consulted for a cough with haemoptotic sputum. Clinical and paraclinical examinations diagnosed small cell carcinoma of the right lung with some controlatéral metastatic nodules. . He was classified as stage T2bN2M1a. Unfortunately, due to lack of financial accessibility to suitable chemotherapy, the patient died after one month. CONCLUSION: Early-onset of bronchial carcinoma in young smokers calls for strengthened control of teenage tobacco use, especially in Africa, where the phenomenon has been taking on alarming proportions.

The historical treatment for stage I non-small cell lung cancer is surgical. Parenchymal amputation is not always possible due to cardiopulmonary comorbidities and stereotactic radiotherapy is one of the alternatives to an invasive procedure. The excellent results observed for inoperable tumors raised the question of this treatment in operable patients. This article presents the data in these two situations and the future perspectives.

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.

The standard management of locally advanced rectal tumors as cT3-T4 and/or N0/N1 is based on preoperative treatment combining radiotherapy of 45 to 50Gy and chemotherapy based on 5-fluorouracil. Intensity-modulated radiotherapy has already shown its interest compared to conformal radiotherapy in other locations, like in pelvic cancer. The role of intensity-modulated radiotherapy in the pre/postoperative treatment of rectal cancers is not a standard of care. Published studies showed its feasibility with the objective of less toxicity with equivalent efficacy.

Robot Assisted Partial Nephrectomy (RAPN) is a standard of care for localized renal tumors. It allows a good carcinological control while limiting complications. Despite numerous benefits, the economic sustainability of robotic assistance remains a challenge in the French health care system. The introduction in our institution of two perioperative nurse-coordinated protocols for patients undergoing RAPN (Enhanced Recovery After Surgery: NP-RAAC in 2015 and Outpatient: Ambu-Rein in 2016) is associated with a shortening of the average length of hospital stay, thus reducing the cost of robotic assisted procedures. With the aim of improving efficiency of nursing support within these protocols, we have introduced digitalized nursing coordination by developing a urological perioperative application: UroConnect®. This device is offered to patients by the coordinating nurses during a preoperative visit. It provides information on the pathology and its surgical management. Self-completed questionnaires sent at key moments collect data from the first month after surgery and detect patients presenting difficulties or complications, allowing the nurses to respond with appropriate care. The application allows a secure discharge, a personalised follow-up and an increase in the patient's autonomy and compliance with care.

Metastatic gastroesophageal adenocarcinoma is a disease with a poor prognosis whose survival did not exceed twelve months until recently. Long limited to conventional cytotoxic chemotherapy protocols, the therapeutic arsenal has been expanded in recent years with the advent of new molecules. In this evolving therapeutic landscape, immunotherapy has also been developed in metastatic gastric cancer. After initial therapeutic trials with mixed or even negative results, immunotherapy was able to make a breakthrough with the checkmate 649 phase III trial demonstrating a significant survival improvement by adding nivolumab to a first-line chemotherapy by XELOX or FOLFOX. The survival benefit provided by nivolumab was greater for patients with tumor CPS≥5 (or even ≥10), whereas it was almost inexistant for tumor CPS<5 (or even<10). Based on this study, a UE approval was obtained from EMA for tumors with a CPS≥5. For HER2-positive metastatic gastric cancer, promising results have been obtained by combination of chemotherapy with anti-HER2 and immunotherapy, and these therapeutic approaches are currently assessed in phase III trials. The variation in the therapeutic response obtained by immunotherapy supposes the existence of molecular subgroups more or less sensitive to these immune checkpoint inhibitors. Some biomarkers have been identified as predictors of response to immunotherapy, such as microsatellite instability, which is probably the most robust of them, but also tumor mutational burden, lymphoplasmacytic infiltration, or EBV tumor positive.

Pancreatic cysts (PC) are common and often discovered incidentally. The distinction between PC is essential, because of the potential malignancy of some lesions requiring surgical resection. The clinical orientation will depend on the clinical history and the radiological characteristics. Indeed, in front of all PCs, it is essential to characterize them using cross-sectional imaging (MRI) in order to highlight the worrisome features requiring further examinations by endoscopic ultrasonography and fine needle aspiration of the cysts to guide the diagnosis. Referral to an expert center will allow to propose to each patient an adequate approach: surgical resection, surveillance according to the recommendations or therapeutic abstention.

Management of oropharyngeal cancer depends on several factors. Immediate surgery or radiotherapy may be considered. If the patient is operable, the choice depends on the extent of the disease, the contributing factors, and the expected functional results. For HPV-positive cancers, studies show comparable efficacy between surgery and radiotherapy. For early-stage cancers, unimodal treatment should be preferred. For HPV-negative cancers, the results of retrospective and observational studies are in favor of surgery. These studies have some limitations. In observational and/or retrospective studies, reclassification biases and the applicability of propensity scores weaken the validity of studies showing differences in management. Tumor and patient comparability are others majors interpretation biases. It is precipitate to conclude that surgery is superior for HPV-negative oropharyngeal cancers. Toxicity, therefore, becomes a criterion of choice for treatment. Unimodal management by surgery allows limited toxicity for the early stages. Surgery has less impact on salivation. Radiotherapy is rather less deleterious for swallowing in the early stages. For the advanced stages of HPV-induced tumors, the non-superiority of surgery should lead to the choice of radiochemotherapy. For oropharyngeal cancers, the possible benefit of surgery in HPV-negative oropharyngeal cancers must be confirmed in randomized studies. For the early stages of oropharyngeal cancer with unimodal treatment, management could be decided by shared decision making.

The incidence of HPV-related oropharyngeal cancers has been increasing in Western countries for several decades. If they are individualized within the latest TNM classification, the current standards of management do not authorize the management of these patients to be singled out. However, their distinct oncogenesis and their excellent prognosis compared to other patients has allowed the development of several clinical trials based on the question of therapeutic de-escalation. This review of the literature aims to take stock of the elements provided by clinical research in recent years.

We present the case of a 12 year old child with a limp. The diagnostic work-up reveals splenomegaly, multifocal bone involvement and abdominal adenopathies. A biopsy of an intra-abdominal lesion shows a lymphoid mass with a nodular architecture composed of poorly defined nodules. We identify large cells with irregular, sometimes poly-lobulated nuclei with a particular immunohistochemical profile. Those "pop-corn" cells are positive for CD20, CD79a, pax-5 and bcl-6 and are negative for CD15, CD30, bcl-2, TdT, CD56 and EMA. There is a diffuse follicular helper T cell population that is located in between the tumour cells. The overall picture is indicative of a nodular lymphocyte predominant Hodgkin lymphoma. Advanced stage of this disease is rare in children and there is currently little data to guide optimal treatment. Because of a stage IV disease, the patient is treated with chemotherapy after which complete metabolic remission is observed. 3.5 years after the initial diagnosis, our patient relapses. He is treated with chemotherapy and an autologous peripheral blood stem cell transplantation. He remains in complete remission since then. This case illustrates the favorable prognosis of the disease even after relapse.

Standard care for rectal cancers relies on both tumor (location relative to the sphincter, T and N stage, sphincter involvement) and patients characteristics. Radical surgery (total mesorectal excision) following short-course radiotherapy (RT) or standard chemo-radiotherapy, associated with induction or consolidation chemotherapy (total neoadjuvant treatment), remains the cornerstone of locally advanced rectal cancer (T3cd, T4 and/or N+) treatment. Nevertheless, for early stages, this radical resection could be avoided in favor of conservative approaches combining RT (external, contact, brachytherapy) with or without chemotherapy (concurrent, induction or consolidative), or even be limited, for good responders, to a local excision with view of organ-preservation strategies. This conservative approach could also be offered selectively to patients with complete clinical response after the induction sequence, irrespective of initial tumor characteristics. The Watch and Wait strategy relies on clinical, endoscopic and radiological evaluations, as well as sustained surveillance. Ongoing studies aim to improve response rates, either with chemotherapy intensification, or RT boost dose escalation with brachytherapy or contact-therapy.
