Survival differences between black and white women with breast cancer.

Several reports have indicated that black women with breast cancer have a poorer prognosis than white women. To investigate this phenomenon and to identify some of the underlying reasons, 172 patients with infiltrating ductal carcinoma of the breast, who were managed similarly, were studied. Survival analysis comparing the two populations with breast cancer revealed that white women had significantly longer overall survival (OS), P = 0.015 by Wilcoxon and 0.019 by log-rank, and borderline significantly longer disease-free survival (DFS), P = 0.04 by Wilcoxon and 0.07 by log-rank. While there was no significant difference in OS and DFS between the two groups with negative nodes, significantly poorer DFS and OS was noted in black patients with one to three positive lymph nodes compared to white patients, P = 0.008. The white patients had a higher incidence of hormone receptor-positive tumors, especially progesterone receptor (P = 0.0016). However, survival analysis failed to show any difference between the black and the white populations based on hormonal receptors. Such findings suggested that further investigation of other factor(s) is warranted.

Long-term results of a combined modality approach in treating inflammatory carcinoma of the breast.

Twenty-eight patients with inflammatory carcinoma of the breast were managed initially by induction chemotherapy consisting of 3 courses of a combination of cyclophosphamide, doxorubicin hydrochloride, and 5-fluorouracil. Twenty-two showed a partial response, and 21 underwent mastectomies. Histopathologic examination of the surgical specimens revealed no residual tumor in 2 breasts, but all 21 patients had residual metastases in their axillary lymph nodes. Postoperatively, they received the same chemotherapy. The other six patients who failed to respond to induction chemotherapy received radical radiation therapy followed by a combination chemotherapy regimen that consisted of cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisone. Any patient in whom chemotherapy failed during the follow-up period was treated by radiation therapy and/or a combination of mitomycin-C and vinblastine as necessary. At the time of diagnosis, 17 patients who had no evidence of distant metastasis, i.e., stage III B disease, had disease-free survival ranging from 5 to more than 84 months, with a median of 30 months, and an overall survival of 7 to more than 120 months with a median of 32 months. The 5-year survival rate was 18%. The other 11 patients who had distant metastases, i.e., stage IV disease, had an overall survival ranging from 4 to 14 months. The results of this approach of initial systemic chemotherapy followed by local-regional cytoreductive therapy, then systemic therapy, might suggest some survival benefits in patients with stage III disease.

Arterial injury from a high pressure water jet: case report.

We report the case of a patient who sustained a high-pressure water jet injury to the thigh while cleaning industrial piping. The patient presented with a puncture wound to the anterior thigh and a pulseless foot. Emergency arteriography was performed that revealed complete disruption of the superficial femoral artery. The patient underwent surgical exploration and debridement, and a successful repair of the disrupted artery was performed with a prosthetic arterial graft. A discussion of high-pressure water jet injuries and their management is presented.

Surgical intervention in children with human immunodeficiency virus infection.

Twenty-one children with human immunodeficiency virus (HIV) infection required surgical intervention during the course of their disease. There were 11 females and 10 males (age range, 3 months to 6 years). The children underwent 54 operative procedures after diagnosis of their disease. These included placement of central venous catheter (23 patients), open lung biopsy (11), incision and drainage of perirectal abscess (4), incision and drainage of soft tissue abscess (5), myringotomy (2), diverting colostomy (3), Nissen fundoplication (1), and other (5). All 21 patients had clinical AIDS by the Centers for Disease Control CDC classification. To date, there have been 12 deaths in the 21 patients (57%) due to progressive deterioration with the patient's disease. Most procedures were adjuncts for diagnostic and therapeutic intervention in a population of children with a uniformly fatal disease. The knowledge of various high risk groups for AIDS must heighten the surgeon's awareness to the growing and significant pediatric segment of the HIV population, the complications of their disease, and the surgeon's limited role in treating these problems.
