RESUMEN

While the vast majority of pediatric Hodgkin lymphoma (HL) is curable, the prognosis of early relapses and refractory diseases remains poor. Recently, the combination of gemcitabine, vinorelbine, and pegylated liposomal doxorubicin (GVD) displayed encouraging results on adults with relapsed/refractory diseases. Here, we retrospectively report the results of the GVD salvage regimen on four pediatric patients of our ward with a heavily pretreated relapsed/refractory HL. Three of them had nodular sclerosis subtype. They achieved a complete remission after two, three, or four courses of GVD and received high-dose chemotherapy followed by a stem-cell transplantation (auto-auto, auto-allo, and auto). They have been in sustained remission respectively for almost 2, 4, and 5 years. The fourth patient had a lymphocyte-depleted subtype which was initially diagnosed as anaplastic large cell lymphoma. After four courses of GVD, his disease stabilized then progressed again. In total, 15 cycles of GVD were applied to the patients. The toxicity of each course of GVD was mainly hematologic. No cardiotoxicity occurred despite a prior exposure to anthracyclines and radiotherapy. Thus, the GVD combination seems to be an effective pre-transplant rescue treatment for pediatric patients.

RESUMEN

BACKGROUND: When invasive components are discovered at mastectomy for vacuum-assisted biopsy (VAB)-diagnosed ductal carcinoma in situ (DCIS), the only option available is axillary lymph node dissection (ALND). The primary aim of this prospective multicenter trial was to determine the benefit of performing upfront sentinel lymph node (SLN) biopsy for these patients. The secondary aim was to determine DCIS factors associated with microinvasion or invasion. METHODS: The SLN procedure was performed during mastectomy, and for positive SLN an ALND was performed during the same intervention. A tissue microarray containing DCIS lesions from the mastectomy specimens was subsequently performed. RESULTS: From May 2008 to December 2010, 228 patients were enrolled from 14 French cancer centers, including 192 eligible patients with pure DCIS on VAB and successful SLN procedures. ALND was avoided for 51 [67 %; 95 % confidence interval (CI), 56-77 %] of all the patients who had microinvasive DCIS or DCIS associated with invasive carcinoma at mastectomy and a negative SLN. Of the 192 patients, 76 (39 %) with VAB-diagnosed DCIS were upgraded after mastectomy to micro (n = 20) or invasive disease (n = 56). The rate of positive SLN for patients with DCIS on VAB was 14 %. High nuclear grade of DCIS was associated with greater risk of microinvasion and invasion, and HER2-amplified DCIS was associated with greater risk of invasion. CONCLUSIONS: Underestimation of invasive components is high when DCIS is diagnosed by VAB in patients undergoing mastectomy. Upfront SLN for patients with VAB-diagnosed extensive DCIS avoids unnecessary ALND for two-thirds of patients with micro or invasive disease on mastectomy.

RESUMEN

OBJECTIVES: To compare, intra-individually, the detection rates of sentinel node on lymphoscintigraphy performed on the day of injection (D0) and on the following day (D1) in breast carcinoma. We also compared 2-day and 1-day protocols in the two groups of patients. METHODS: The 2-day and 1-day protocols included 76 patients in group 1 and 23 patients in group 2. Patients from group 1 underwent lymphoscintigraphy twice--at 2 h (lymphoscintigraphy 1) and 18 h (lymphoscintigraphy 2) post-injection at four sites periareolar using 99mTc sulfur colloid. Patients from group 2 underwent lymphoscintigraphy only at 2 h post-injection. The detection rates and the number of sentinel nodes were compared in the two lymphoscintigraphy examinations for group 2. RESULTS: The detection rate on lymphoscintigraphy in group 1 was 92% at D0 and 96% at D1. The overall agreement between lymphoscintigraphy 1 and lymphoscintigraphy 2 was 69/76 (91%). In 2/76 women, the sentinel node disappeared at D1 on lymphoscintigraphy, but remained detectable during surgery, and in 5/76 women, the sentinel node appeared at D1 on lymphoscintigraphy. The mean number of sentinel nodes detected on lymphoscintigraphy was 2.05+/-0.14 at D0 and 1.76+/-0.11 at D1 (P=0.004) in group 2, the detection rate of the sentinel node was 20/23 (87%). CONCLUSION: Our study demonstrated that for patients undergoing the 2-day protocol for sentinel node procedure in early stage breast cancer, the optimal imaging time would be to perform lymphoscintigraphy 1 h after injection, with the possibility of imaging patients the following day in cases where lymphoscintigraphy was negative.
