NCT06868238
The standard surgical approach for all patients undergoing mastectomy for the treatment of non-invasive, ductal carcinoma in situ (DCIS) is to perform axillary lymph node staging through use of a traditional sentinel lymph node biopsy (SLNB) procedure where the lymph nodes that drain the breast first are removed at the time of mastectomy. This recommendation for traditional SLNB is due to the risk of finding invasive cancer during surgical evaluation of the mastectomy specimen and the inability to accurately map the lymphatic channels once the breast is removed. In a study by Herremans et al, the majority of traditional SLNBs were demonstrated to be unnecessary. By using Magtrace, a novel iron based lymphatic mapping agent, a delayed SLNB could eliminate these unnecessary traditional SLNBs. Magtrace, or superparamagnetic oxide (SPIO), was developed in 2018. Unlike traditional mapping agents of blue dye and technetium that clear the body within 24-48 hours, Magtrace remains in the lymph nodes for at least 4 weeks. Magtrace's ability to remain in the lymph node allows accurate mapping of the lymph nodes at the time of the mastectomy with the ability to return to the operating room for a delayed sentinel lymph node biopsy if invasive cancer is found on final pathology. This study will investigate whether the use of Magtrace will successfully allow patients with DCIS undergoing mastectomy to avoid undergoing SLNB.

Lesbian, Gay, Bisexual, Transgender, Intersex, Queer, Asexual, and other sexually or gender diverse (LGBTIQA+) communities in many countries face high levels of mental health problems compared to the general population. This is often due to discrimination, being excluded, abuse, and unfair treatment. In many low- and middle-income countries, including Nepal, the mental health needs of LGBTIQA+ people are not met, and the violence they experience is often ignored because they are seen as breaking gender norms. The low number of trained mental health specialists in a country like Nepal imply that any short-term effort to alleviate the mental health problems among LGBTIQA+ must rely on other type of support workers such as peers. There is growing evidence that help from community members-such as counselling given by non-professionals-can improve mental well-being. Considering that discrimination of LGBTIQA+ is common also within the health services, this study will look at whether peer counselling-support provided by trained LGBTIQA+ community members-can work well in Nepal. We have improved a counselling program called 'Problem Management Plus' (PM+), developed by the World Health Organization, by adding new parts that focus on reducing the risk of some of the contributing causes of mental distress, namely violence, marginalisation and loneliness. The added components include safety planning, counselling that builds confidence and strength, and goal setting strategies to help study participants use the skills they learn and reach the desired impact. In addition, peer-led monthly group meetings will be conducted to enhance social cohesion, strengthen interpersonal networks, and reduce feeling of loneliness. The study uses a community based participatory research approach, meaning LGBTIQA+ people are invited to give inputs throughout the study from study design to being involved as peer advocates to deliver the counselling. The trial will recruit at least 960 LGBTIQA+ individuals aged 18 to 55 years living in seven districts of Nepal. Study participants will be randomly allocated to one of three arms: one arm receiving individual augmented PM+ counselling with six weekly sessions; one arm receiving the individual augmented PM+ counselling followed by 11 monthly group sessions; and one control arm. There will be a one year follow-up to examine whether the peer support helps improve mental health and reduce exposure to violence among LGBTIQA+ people. The study findings will help guide programmes to improve the mental health of LGBTIQA+ in other low- and middle-income countries where they also experience discrimination, exclusion, and violence.
