Patterns Of Breast Recurrence In A Pilot Study Of Brachytherapy Confined To The Lumpectomy Site For Early Breast Cancer With Six Years' Minimum Follow-Up, Francisco Perera, Edward Yu, Jay Engel, Ronald Holliday, Leslie Scott, Frank Chisela, Varagur Venkatesan

PURPOSE: In this pilot study of high-dose-rate brachytherapy to the lumpectomy site as the sole radiation, ipsilateral and contralateral breast recurrences are documented with specific attention to the location of recurrence relative to the lumpectomy site. METHODS: Between March 1992 and January 1996, 39 patients with T1 (32 patients) and T2 breast cancers received 37.2 Gy in 10 fractions (b.i.d.) over 1 week prescribed to a volume encompassing the surgical clips. Thirteen received adjuvant tamoxifen, and 4 received chemotherapy. Follow-up included annual bilateral mammograms and clinical breast examination every 3 to 6 months. Whereas 13 patients had intraoperative implantation of …
Shifting From Hypofractionated To "Conventionally" Fractionated Thoracic Radiotherapy: A Single Institution's 10-Year Experience In The Management Of Limited-Stage Small-Cell Lung Cancer Using Concurrent Chemoradiation, Gregory Videtic, Pauline Truong, A. Dar, Edward Yu, Larry Stitt

Edward Yu
PURPOSE: To perform a retrospective review of a single institution's 10-year experience in treating limited-stage small-cell lung cancer (LS-SCLC) with a concurrent chemoradiation regimen modeled after the experimental arm of a randomized National Cancer Institute of Canada trial in which hypofractionated radiotherapy started with cycle 2 of chemotherapy. We then looked at the impact on patient outcomes of changing the RT during the course of the decade to a "conventionally" (2 Gy) fractionated regimen, with a focus on toxicity and survival rates. METHODS AND MATERIALS: Between 1989 and 1999, 215 LS-SCLC patients received six cycles of chemotherapy consisting of cyclophosphamide, …
Offering To Return Results To Research Participants: Attitudes And Needs Of Principal Investigators In The Children's Oncology Group, Conrad Fernandez, Eric Kodish, Susan Shurin, Charles Weijer
Offering To Return Results To Research Participants: Attitudes And Needs Of Principal Investigators In The Children's Oncology Group, Conrad Fernandez, Eric Kodish, Susan Shurin, Charles Weijer

PURPOSE: The offer to return a summary of results to participants after the conclusion of clinical research has many potential benefits. The authors determined current practice and attitudes and needs of researchers in establishing programs to return results to research participants.
METHODS: An Internet survey of all 236 principal investigators (PIs) of the Children's Oncology Group in May 2002 recorded PI and institutional demographics, current practice, and perceived barriers to and needs of PIs for the creation of research results programs.
RESULTS: One hundred fifty (63.8%) PIs responded. Few institutions (n = 5) had established, comprehensive programs to offer the …
Continued Cigarette Smoking By Patients Receiving Concurrent Chemoradiotherapy For Limited-Stage Small-Cell Lung Cancer Is Associated With Decreased Survival, Gregory Videtic, Larry Stitt, A. Dar, Walter Kocha, Anna Tomiak, Pauline Truong, Mark Vincent, Edward Yu

PURPOSE: To determine the impact of continued smoking by patients receiving chemotherapy (CHT) and radiotherapy (RT) for limited-stage small-cell lung cancer (LSCLC) on toxicity and survival. PATIENTS AND METHODS: A retrospective review was carried out on 215 patients with LSCLC treated between 1989 and 1999. Treatment consisted of six cycles of alternating cyclophosphamide, doxorubicin, vincristine and etoposide, cisplatin (EP). Thoracic RT was concurrent with EP (cycle 2 or 3) only. Patients were known smokers, with their smoking status recorded at the start of chemoradiotherapy (CHT/RT). RT interruption during concurrent CHT/RT was used as the marker for treatment toxicity. RESULTS: Of …
