Objective To evaluate the effect of extensive resection and immediate reconstruction based on classification of abdominal wall defects for patients with abdominal wall neoplasms.Methods From Jan 1999 to May 2016,112 patients with abdominal wall neoplasms were treated with extensive resection,including Type Ⅰ (n =20),Type Ⅱ (n =45) and Type Ⅲ (n =47).Immediate abdominal wall reconstruction comprised primary sutures or free skin graft for Type I defects,component separation (CST) with or without a prosthetic or biological mesh reinforcement for Type Ⅱ defects and pedicled or vascularized myocutaneous flap with or without a prosthetic or biological mesh or prosthetic + biological mesh with or without CST for Type Ⅲ defects.Results The average follow up was 76.86 ± 21.22 months,3 patients developed flap necrosis,9 patients suffered from wound infection.Local recurrence was observed in 20 patients,35 patients developed distant metastasis.Conclusions The optimal strategy based on the abdominal wall defect classification for immediate reconstruction of huge abdominal wall defects is safe and effective after resection of abdominal wall neoplasms.

Hematological malignancies are suitable diseases for radioimmunotherapy because of their high sensitivity to radiation and well-defined immunophenotypes. Beta emitters like 131I and 90Y have achieved some outcomes in radioimmunotherapy of hematological malignancies. Compared with beta particles, alpha particles have higher linear energy transfer, greater relative biological effects and shorter range, which give alpha particles the ability to kill tumor cells more effectively with less damage to normal tissue. This review summarizes the current studies of targeted alpha-particle therapy in hematological malignancies.
