BACKGROUND: Cancer is a major public health problem in France. Idiopathic venous thromboembolic disease may be one of the modes of discovery. Few studies have been performed on this subject in primary care. The general practitioner plays a key role in the diagnosis for which a more codified approach seems desirable. The aim was to study how general practitioners conceive the search for cancer in patients with idiopathic venous thromboembolic disease in primary care.
METHODS: A qualitative study, inspired by the grounded theory approach, was carried out using semi-structured interviews with 12 established general practitioners. It was conducted from May to July 2022. The interview guide was developed based on data from the literature.
RESULTS: Idiopathic venous thromboembolic disease as a mode of cancer discovery in primary care was a well-known topic among general practitioners but remained a difficult exercise in practice. Our study revealed similarities in their practices: a complete anamnesis, clinical examination, verification of screening tests, and finally a TAP scan. They emphasized the importance of collaboration with angiologists and asked for a more codified management.
CONCLUSIONS: The question of etiology of cancer remains unanswered. General practioners would like to be made aware of a common, codified attitude. This raises the question of the applicability of the recommendations. The aim is to avoid misdiagnosing a cancer or delaying a diagnosis, while at the same time, not unnecessarily exposing certain patients to excessive investigations when these are not needed. So, it is time to think about better dissemination of recommendations, tools to help GPs easily finding what they need among the multitude of existing recommendations and tools, to establish better collaboration between general practice and hospital medicine, and between general practice and specialist medicine in order to improve cancer diagnosis as early as possible.

BACKGROUND: Interventional bronchoscopy is now the standard treatment for tracheobronchial narrowing due to tumor. The objective of our study was to analyze long-term survival and complications occurring in patients with malignant airway obstruction.
METHODS: We retrospectively studied the data from 93 patients treated between 2008 and 2019.
RESULTS: One hundred and eleven therapeutic bronchoscopies were performed. Sixty-seven patients had primary lung cancer, in 17 had tumors of another origin and 9 patients had benign or local lung tumors. Thulium laser was frequently used prior to tumor enucleation and to restore hemostasis. Seventy-one silicone stents were inserted. The death rate at the time of the procedure was 1.8% and immediate complication occurred in 9.9% of the patients. Long-term survival was significantly better for patients with cancer from other origins than in those with primary lung cancer (615.5days versus 177.9days). On the other hand, there was no significant difference in long-term survival between patients with locally advanced and metastatic lung cancer with endobronchial lesions treated by stent and those who were not (234.2days versus 164.6days). All patients with benign or with locally malignant tumors were still alive.
CONCLUSIONS: Therapeutic bronchoscopy increases the long-term survival of patients with malignant airway obstruction. The risk-benefit ratio was favorable.

For many years, the intraocular lymphatic system and particularly the drainage of the aqueous humor by this system have been considered non-existant. Our study is the first to demonstrate, in a dynamic in vivo fashion, the existence of lymphatic drainage in the mouse eye. This has become possible with lymphoscintigraphy with nano-molecules of rhenium sulphide, marked by technetium-99m and injected into the anterior chamber of the mouse eye. Readings were taken using an experimental gamma camera specially built for the small animal. The hypothesis of a \"uveolymphatic\" drainage pathway within the ciliary body, contributing to aqueous outflow, has recently been highlighted by new improvements in microbiology (discovery of lymphatic endothelial-specific markers) and imaging. This new pathway may lead to many prospects: the development of techniques for visualization and quantification of this in vivo lymphatic flow may help to increase our understanding of the physiopathology and perhaps treatment of chronic glaucoma as well as neoplastic conditions.
