NEW YORK-Patients with advanced colorectal cancer experienced a significantly better response rate with a combination of oxaliplatin (Eloxatin) and infusional fluorouracil (5-FU)/leucovorin (LV), compared with infusional 5-FU/LV or oxaliplatin alone, Mace Rothenberg, MD, of Vanderbilt University Medical Center, said at the Chemotherapy Foundation Symposium XX. The data, presented for the first time in the United States, were the basis for the recent FDA approval of oxaliplatin.
WASHINGTON-A federal court has invalidated the FDA’s "Pediatric Rule" after concluding that its requirement that drug companies test the safety of adult drugs in children is contrary to the intent of Congress.
ORLANDO, Florida-Updateddata from two separate studiesratify earlier results showing thatfollowing CHOP (cyclophosphamide[Cytoxan, Neosar], doxorubicinHCl, vincristine [Oncovin],prednisone) with radiation improvesresults for patients with early-or limited-stage non-Hodgkin’slymphoma (NHL), according todata reported at the 43rd AnnualMeeting of the American Society ofHematology (abstract 3023) .
PALO ALTO, California-Varian Medical Systems, Inc. has received 510(k) clearance from the FDA for Acuity, a new digital imaging product that integrates planning, simulation, and verification software for treating cancer with radiation therapy. It works with Varian’s RPM Respiratory Gating System to track tumor motion during simulation and verification. It is intended to accelerate adoption of intensity modulated radiation therapy (IMRT). By performing patient set-up and treatment plan verification, Acuity frees the linear accelerator to be used exclusively for treatment delivery, Varian said in a press release announcing the new product.

NEW ORLEANS-Having a previous pregnancy improves the prognosis for women who develop early-stage breast cancer later in life, according to a study presented at the 44th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (abstract 152). The findings suggest that a more aggressive treatment approach should be considered for those patients who have not had a pregnancy.
Plastic 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.
This 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.
Drs. Konner and O’Reilly have provided a thorough review of current perspectives on pancreatic cancer. The disease is lethal, difficult to diagnose in its early stages, and resistant to standard chemotherapy regimens. Surgery can be curative if performed when the tumor is small (< 2 cm), but only a minority of patients have small tumors.
