RESUMEN
OBJECTIVE: Microvascular free-tissue transfer (M-FTT) is a surgical technique for traumatic injuries that allows tissue reconstruction based on donor tissue composition. The aim of this study is to describe the surgical experiences of M-FTT for reconstruction of complex soft tissue injuries in the lower extremities of a Hispanic population. METHODS: This is a descriptive study of all M-FTT procedures performed by a single plastic surgeon from 2012 to 2016 at Puerto Rico Medical Center. Demographics, admission diagnosis, mechanism of trauma, type of free flap, co-morbidities, length of stay, donor site and complications were evaluated. RESULTS: Eight patients who underwent single M-FTT procedures at lower extremity were enrolled in the study. The average age at time of surgical reconstruction was 36.9+13.2 years with six males and two females. The transfer procedures were performed using donor sites of six rectus abdominis flaps and 2 radial forearm flaps. Posterior tibial artery was used in 62.5% and popliteal artery were used in 37.5% as recipient arteries. Average surgical time was 4.4+0.7 hours with an average length of hospital stay of 22.9+20.1 days. Post-operative complications were reported in three M-FTT procedures: two cases who suffered venous thrombosis and one case who suffered partial necrosis. CONCLUSION: The M-FTT offers an adequate surgical option for patients who present with complex soft tissue traumatic injuries at the lower extremities.

The case of a 27-year-old Hispanic female who presented with an occipito-parietal tumor after suffering trauma to the area. A physical examination revealed no tenderness to palpation and with evidence of healing ulcerations. The biopsy was consistent with a synovial sarcoma. A wide excision of the mass (15cm x 14cm x 6cm) followed by a pericranial flap was performed. A follow-up CT showed recurrence involving the parietal sagittal sinus. After a second biopsy the mass was determined to be a small-cell sarcoma, consistent with Ewing's sarcoma. Chemotherapy included 8 cycles of doxorubicin, vincristine, and cyclophosphamide, with alternating cycles of etoposide and ifosfamide. A year later, a second wide excision of the mass was performed, followed by bilaminate skin substitute and skin graft placement for reconstruction of the soft-tissue defect. After chemotherapy, a follow-up PET scan showed no signs of re-uptake in any soft tissue or skeletal structures. After 2 years, the patient remains in complete remission.

We describe a 79-yr-old man with a history of androgen-independent metastatic prostate cancer treated with exogenous estrogens presenting with bilateral breast masses associated with bilateral axillary lymphadenopathy. Although the findings on physical examination with the concomitant history of estrogen therapy for metastatic prostate cancer raised the clinical suspicion of breast cancer, fine-needle aspiration (FNA) cytology identified the lesions as multiple myeloma.

BACKGROUND: Survival in breast cancer maybe more accurately predicted by a scoring system based on the biologic characteristics of the tumor such as diameter, number of involved nodes, and hormone receptor status than by conventional staging. METHODS: Medical records of 419 patients with a diagnosis of breast cancer from a university hospital between 1997 and 2002 were reviewed. Tumor characteristics were given a value reflecting the impact on survival. Tumor diameter was assigned 1 point per cm, specifically: 1 point for 0.1 to 1 cm, 2 points for 1.1 to 2 cm, 3 points for 2.1 to 5 cm, and 4 points for 5.1 cm and over. Nodal status was assigned 1 point if the patient had 1 to 3 positive nodes, 5 points if 4 to 10 positive nodes were found, and 10 points if more than 10 nodes were identified. Hormone receptor status was given 1 point if either estrogen or progesterone receptors were not present or 2 points if both were absent. The breast cancer severity score (BCSS) was used to analyze overall and disease-free survival by Kaplan-Meier analysis. Significance of differences in survival was determined by log-rank analysis. RESULTS: An increased severity score was inversely proportional to overall and disease-free survivals. A BCSS of greater than 7 was most predictive of outcome with 5-year survival of 68%; and a BCSS of less than 7 had a 5-year survival of 98% (P = 0.0028). A BCSS of greater than 7 also discriminated disease-free survival within stage II (P = 0.02) and stage III (P = 0.01). CONCLUSIONS: The BCSS provides a better resolution of outcome than traditional staging, and works both for overall survival and within specific stages. Using the BCSS, management and follow-up can be specifically tailored for low- and high-risk patients.

HYPOTHESIS: Surgical outcomes from a breast cancer-screening program of low-income women are similar to those of other screening programs. DESIGN: Prospective cohort. SETTING: Federally funded screening program. PATIENTS: A total of 15730 women. INTERVENTIONS: A total of 23149 mammograms, 20396 with concomitant clinical breast examination, from January 1, 1997, through December 31, 2001. OUTCOME MEASURES: American College of Radiology scores; associated surgery consultations, biopsies, operations, and pathology results. RESULTS: Most (20868) of the 21296 mammograms assigned an American College of Radiology score were benign; only 428 (2%) were suspicious. Resulting from suspicious clinical breast examinations, the group with American College of Radiology scores of 1 to 3 accounted for 45%, 18%, and 10% of recommended surgical consultations, biopsies, and cancers detected, respectively. A rate of 12.3 cancers per 1000 women was found, greater than with other screening programs. Compliance with therapy was 97%. CONCLUSIONS: This screening program had a higher rate of advanced cancers. Clinical breast examination was an important component, and compliance with surgical recommendations was excellent.
