local Recurrence Risk after Skin-sparing and Conventional Mastectomy: A 6-year Follow-up

In this study, the records of all patients at the University of Texas M. D. Anderson Cancer Center with T1 or T2 breast cancer who were treated between March of 1986 and November of 1990 with mastectomy followed by immediate breast reconstruction were reviewed for the presence of recurrent disease. Patients with in situ disease were not included. Patients were included in the study if a local recurrence occurred (regardless of the length of follow-up) or if a follow-up of 6 years or longer could be obtained. Patients were grouped according to the use or nonuse of skin-sparing mastectomy, by tumor stage, and by nuclear grade of the tumor. The series included 154 patients, of whom 114 had skin-sparing mastectomies and 40 had nonskin-sparing mastectomies. The local recurrence rate in the skin-sparing mastectomy group was 7.0 percent, whereas in the nonskin-sparing mastectomy group it was 7.5 percent. The sample size in the nonskin-sparing mastectomy group was too small for meaningful statistical analysis, but the data suggest that there is no clinically important difference in recurrence rates between the two groups. We conclude that the use of skin-sparing technique for early breast cancer patients does not significantly increase the risk of tumor recurrence after mastectomy.

Soft tissue reconstruction following hemipelvectomy

BACKGROUND Resection of primary and metastatic pelvic bone disease may result in large soft tissue deficits. Guidelines for soft tissue reconstruction following pelvic bone resection were evaluated in a retrospective study. METHODS Over a 5-year period 21 patients (31%) required soft tissue reconstruction following pelvic bone resection. Data on these patients were retrieved from case records. RESULTS Twelve patients underwent immediate, planned reconstruction, 1 a two-stage reconstruction, and 8 patients required a delayed procedure for complications after bone resection and primary closure. Soft tissue reconstruction was usually accomplished with muscle-based flaps; (25 flaps in 20 patients: 20 pedicled, 5 free), or with skin grafts alone (1 patient). Specific postreconstruction complications occurred in 9 patients, 5 in flaps based on the ipsilateral rectus muscle. CONCLUSION Flap closure is indicated to achieve primary closure and eliminate deadspace. The ipsilateral rectus muscle should be used with caution and contralateral-based rectus flaps considered. Indications for free flaps include the size and location of the defect and availability of tissue from an amputated limb.
