Contribution of the cadaveric recirculation system in the anatomical study of lymphatic drainage of the ovary: applications in the management of ovarian cancer.

PURPOSE: The present knowledge about lymphatic drainage of the ovary is based on carcinological studies, but it has only rarely been studied under physiological conditions. However, it is one of the preferential routes of dissemination in ovarian cancer, and understanding it is therefore vital for optimal carcinological management.Our purpose was to evaluate the feasibility of an innovative technique to study the lymphatic drainage territories of the ovary using a recirculation module on the cadaveric model. METHODS: We injected patent blue into the cortex of twenty "revascularised" cadaver ovaries with the Simlife recirculation model. We observed the migration of the dye live and described the drainage territories of each ovary. RESULTS: We observed a staining of the lymphatic vessels and migration of the dye in all the subjects, systematically ipsilateral to the injected ovary. We identified a staining of the lumbo-aortic territory in 65% of cases, with a preferential lateral-caval involvement (60%) for the right ovary and lateral-aortic territory (40%) for the left ovary. A common iliac involvement was observed in only 10% of cases. In 57% of cases, the staining of the lumbo-aortic territory was associated with a staining of the suspensory ligament. The pelvic territory was involved in 50% of cases, with an external iliac staining in 25% of cases and internal in 20%. CONCLUSION: Our study provides for a better understanding of lymphatic drainage of the ovary using a new detection method, and allows the possibility of improving the teaching for operators with a realistic model. Continuation of this work could lead to considering more targeted and thus less morbid lymph node sampling for lymph node staging in early-stage ovarian cancer.

Impact of the first lockdown for coronavirus 19 on breast cancer management in France: A multicentre survey.

OBJECTIVE: This study examined the impact of lockdown for SARS-CoV-2 on breast cancer management via an online survey in a French multicentre setting. MATERIAL AND METHODS: This is a multicentre retrospective study, over the strict lockdown period from March 16th to May 11th, 2020 in metropolitan France. 20 centres were solicited, of which 12 responded to the survey. RESULTS: 50% of the centres increased their surgical activity, 33% decreased it and 17% did not change it during containment. Some centres had to cancel (17%) or postpone (33%) patient-requested interventions due to fear of SARS-CoV-2. Four and 6 centres (33% and 50%) respectively cancelled and postponed interventions for medical reasons. In the usual period, 83% of the centres perform their conservative surgeries on an outpatient basis, otherwise the length of hospital stay was 24 to 48 h. All the centres except one performed conservative surgery on an outpatient basis during the lockdown period, for which. 8% performed mastectomies on an outpatient basis during the usual period. During lockdown, 50% of the centres reduced their hospitalization duration (25% outpatient /25% early discharge on Day 1). CONCLUSION: This study explored possibilities for management during the first pandemic lockdown. The COVID-19 pandemic required a total reorganization of the healthcare system, including the care pathways for cancer patients.
