NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines

Ductal carcinoma in situ (DCIS) of the breast represents a heterogeneous group of neoplastic lesions in the breast ducts. The goal for management of DCIS is to prevent the development of invasive breast cancer. This manuscript focuses on the NCCN Guidelines Panel recommendations for the workup, primary treatment, risk reduction strategies, and surveillance specific to DCIS.

Clinical practice guidelines in oncology

RESULTS The two chemotherapy regimens did not differ significantly with respect to freedom from treatment failure (P = 0.39) or overall survival (P = 0.61). At 5 years, the rates of freedom from treatment failure were 93.0% (95% confidence interval [CI], 90.5 to 94.8) with the four-cycle ABVD regimen and 91.1% (95% CI, 88.3 to 93.2) with the two-cycle regimen. When the effects of 20-Gy and 30-Gy doses of radiation therapy were compared, there were also no significant differences in freedom from treatment failure (P = 1.00) or overall survival (P = 0.61). Adverse events and acute toxic effects of treatment were most common in the patients who received four cycles of ABVD and 30 Gy of radiation therapy (group 1). CONCLUSIONS In patients with early-stage Hodgkin’s lymphoma and a favorable prognosis, treatment with two cycles of ABVD followed by 20 Gy of involved-field radiation therapy is as effective as, and less toxic than, four cycles of ABVD followed by 30 Gy of involved-field radiation therapy. Long-term effects of these treatments have not yet been fully assessed. (Funded by the Deutsche Krebshilfe and the Swiss Federal Government; ClinicalTrials.gov number, NCT00265018.)

Reduced treatment intensity in patients with early-stage Hodgkin's lymphoma.

BackgroundIt is unclear whether patients with early-stage Hodgkin’s lymphoma and negative findings on positron-emission tomography (PET) after three cycles of chemotherapy with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) require radiotherapy. MethodsPatients with newly diagnosed stage IA or stage IIA Hodgkin’s lymphoma received three cycles of ABVD and then underwent PET scanning. Patients with negative PET findings were randomly assigned to receive involved-field radiotherapy or no further treatment; patients with positive PET findings received a fourth cycle of ABVD and radiotherapy. This trial assessing the noninferiority of no further treatment was designed to exclude a difference in the 3-year progression-free survival rate of 7 or more percentage points from the assumed 95% progression-free survival rate in the radiotherapy group. ResultsA total of 602 patients (53.3% male; median age, 34 years) were recruited, and 571 patients underwent PET scanning. The PET findings were negative i...

Hodgkin's lymphoma: ESMO Clinical Practice Guidelines for diagnosis, treatment and follow-up

BACKGROUND: Treatment of early-stage Hodgkin's disease is usually tailored in line with prognostic factors that allow for reductions in the amount of chemotherapy and extent of radiotherapy required for a possible cure. METHODS: From 1993 to 1999, we identified 1538 patients (age, 15 to 70 years) who had untreated stage I or II supradiaphragmatic Hodgkin's disease with favorable prognostic features (the H8-F trial) or unfavorable features (the H8-U trial). In the H8-F trial, we compared three cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) combined with doxorubicin, bleomycin, and vinblastine (ABV) plus involved-field radiotherapy with subtotal nodal radiotherapy alone (reference group). In the H8-U trial, we compared three regimens: six cycles of MOPP-ABV plus involved-field radiotherapy (reference group), four cycles of MOPP-ABV plus involved-field radiotherapy, and four cycles of MOPP-ABV plus subtotal nodal radiotherapy. RESULTS: The median follow-up was 92 months. In the H8-F trial, the estimated 5-year event-free survival rate was significantly higher after three cycles of MOPP-ABV plus involved-field radiotherapy than after subtotal nodal radiotherapy alone (98% vs. 74%, P<0.001). The 10-year overall survival estimates were 97% and 92%, respectively (P=0.001). In the H8-U trial, the estimated 5-year event-free survival rates were similar in the three treatment groups: 84% after six cycles of MOPP-ABV plus involved-field radiotherapy, 88% after four cycles of MOPP-ABV plus involved-field radiotherapy, and 87% after four cycles of MOPP-ABV plus subtotal nodal radiotherapy. The 10-year overall survival estimates were 88%, 85%, and 84%, respectively. CONCLUSIONS: Chemotherapy plus involved-field radiotherapy should be the standard treatment for Hodgkin's disease with favorable prognostic features. In patients with unfavorable features, four courses of chemotherapy plus involved-field radiotherapy should be the standard treatment. (ClinicalTrials.gov number, NCT00379041 [ClinicalTrials.gov].).

Chemotherapy plus involved-field radiation in early-stage Hodgkin's disease

6505 Background: EORTC and GELA aim at reducing acute and late side effects of treatment in early stages HL, without jeopardizing high event-free survival (EFS) and overall survival (OS) rates already achieved. Methods: From October 1998 to May 2004, 1591 patients with stage I-II HL were enrolled into 2 trials based on 4 prognostic factors: age, symptoms, number of involved areas, MT-ratio. The H9-F trial compared 36 Gy involved field radiotherapy (IF-RT) vs 20 Gy IF-RT vs no RT in patients in complete remission (CR(u)) after 6 cycles of EBVP. The H9-U trial compared 6 cycles of ABVD vs 4 cycles of ABVD vs 4 cycles of BEACOPP baseline, followed by 30 Gy IF-RT in all arms, in patients with unfavorable clinical features. Results: In the H9-F trial, of the 783 patients enrolled, 619 (79%) achieved a CR(u) and were randomized. Inclusion of patients in the no-RT arm was stopped in May 2002, because stopping rules were met (ie. > 20% of events). Inclusion in the other 2 arms continued until May 2004. After a me...

First results of the EORTC-GELA H9 randomized trials: the H9-F trial (comparing 3 radiation dose levels) and H9-U trial (comparing 3 chemotherapy schemes) in patients with favorable or unfavorable early stage Hodgkin’s lymphoma (HL)

Summary. Clinical studies in hairy cell leukaemia (HCL) have linked the frequent occurrence of infections due to intracellular pathogens and a profound monocytopenia. More recently, dendritic cells (DC), a subset of which are related to monocytes, were shown to be the professional antigen-presenting cells which stimulate the adaptive immune response. Using membrane markers and flow cytometry, we determined in peripheral blood whether various DC subsets and monocytes were impaired in HCL. Lymphoid and myeloid DC were virtually absent in five HCL patients with active disease. After treatment, both DC and monocytes recovered slowly. The decrease in DC suggests that defective antigen presentation could affect susceptibility to intracellular pathogens in HCL.
