Dermatological surgeons wear many hats to care for subjects with skin cancer. While their role in cancerous tissue removal results in superior cure rates, there is also a need for skilled excisional repair and effective wound healing regimens so the subject can heal with the least amount of scarring necessary. As such, numerous techniques have been developed for reducing the morbidity associated with excessive scarring. Various flaps and grafts allow the surgeon to approximate skin texture, thickness and adnexa with respect to the residual surrounding tissue. Optimal cosmetic and functional outcomes require close wound approximation with minimal static tension along the wound edge. In addition, there are post-operative wound care techniques that range from special dressings to cosmetic scar modification. To date, most surgical wounds are allowed to heal at least partially before scar revision or modulation is attempted. Botulinum toxin presents a unique opportunity for surgeons to affect scar formation throughout the duration of the healing process. These effects are likely independent and adjunctive to any and all wound care techniques, and are primarily attributed to a reduction in dynamic tension on the wound edges. Most importantly, botulinum toxin's one time dosing requirements with respect to reduced scar formation precludes the variance inherent to standard wound care practices. Therefore, it has been proposed that for selected subjects, botulinum toxin may be a safe, effective and reliable means for improved post-excisional repair outcomes. Botulinum toxin has been investigated as an inhibitor of excessive, post-excisional scar formation in plastic surgery and Otorhinolaryngology literature. However, these promising studies have yet to combine objective assessment measures of human scar formation in a randomized controlled trial. In addition, there are currently no formal studies of botulinum toxin as a prophylactic against excess scarring in the dermatological literature. Fortunately, Botulinum toxin dosing in the forehead for the purposes of inhibiting excessive scar formation is comparable to the amount given for cosmetic purposes, which is commonplace in dermatology and well-studied.

The main purpose of this study is to establish a safe and tolerable dose combination (the "maximum tolerated dose") of selinexor and ixazomib when used together for the treatment of patients with certain types of advanced sarcoma. The study will enroll patients with advanced dedifferentiated liposarcoma, malignant peripheral nerve sheath tumor, alveolar soft part sarcoma and Ewing sarcoma. Future studies to further evaluate the safety and anti-cancer efficacy of this treatment for sarcoma will use the dose combination determined in this study.
