Plastic Surgery: A Component in the Comprehensive Care of Cancer Patients
December 1st 2002Plastic surgical reconstruction extends the capabilities of surgical and radiation therapy for cancer patients. Resection defects that are large, involve functional structures, aesthetically sensitive areas, and/or are at increased risk for wound healing complications are successfully reconstructed with a wide variety of techniques. Cancer and the complications of cancer treatment can involve virtually any area of the body, and to address every potential circumstance, the breadth of oncologic reconstruction must be extensive. A multidisciplinary team approach is the optimal method of cancer treatment, and plastic surgical reconstruction has become a critical component of that treatment, with the ability to restore form and function to the involved areas.
Plastic Surgery: A Component in the Comprehensive Care of Cancer Patients
December 1st 2002This article underscores what I believe is an important concept in the current state of the art of cancer therapy-namely that reconstructive plastic surgery is a key component in the treatment of many cancer patients. Clearly, the treatment of advanced-stage malignancies is now interdisciplinary, multimodal, and comprehensive. Chemotherapy and radiation therapy are becoming increasingly complementary modalities in the treatment of patients with more advanced disease.

Clinical Trials in Ovarian Cancer, Part 2
The American Cancer Society has estimated that 23,300 women will develop ovarian cancer in 2002, and 13,900 women will die from the disease.[1] The 5-year survival rate is about 80% for women with stage I disease, 50% for women with stage II disease, 25% for women with stage III disease, and 15% for women with stage IV disease. Among women with advanced-stage disease, optimal debulking surgery, as well as platinum/taxane-based adjuvant therapy prolongs disease-free and median survival.[2,3] Population-based data suggest that guidelines for therapy are not uniformly followed in community practice.[4] In addition, older patients appear to receive less aggressive treatment than younger patients.
