RESUMO
OBJECTIVE: To evaluate role of dose dense neo-adjuvant chemotherapy (NACT) prior to standard concurrent chemo-radiation (CCRT) in locally advanced cervical cancer. METHODS: Between June 2010 and December 2011, 28 patients (median age - 51 years, range, 35 to 67 years) with locally advanced cervical cancer received NACT using paclitaxel (60 mg/m(2)) and carboplatin (AUC-2) weekly for 6 doses. After a mean interval of 15 days (range 7-23 days), the patients then received definitive radiation and concomitant weekly infusion of cisplatin (40 mg/m(2) for 6 doses). Response to concurrent chemo-radiation and toxicity were end points. RESULTS: Following NACT, 67.8% of patients responded; complete (CR) - 2(7.1%), Partial (PR) - 17 (60.7%), stable 7 (25.0%) and 2 patients (7.1%) progressed. 24 of 28 patients received CCRT; 23/24 achieved CR. 22 of 23 complete responders continue to be in CR at a median follow-up of 12 months (range, 7 to 24 months). Grade III/IV neutropenia was the main hematological toxicity seen in 28.5% and 29% of patients, respectively during NACT and CCRT. CONCLUSIONS: Neoadjuvant chemotherapy with dose dense weekly paclitaxel and carboplatin followed by standard CCRT is a feasible approach and is associated with a high response rate in locally advanced cervical cancer.

The authors evaluated complications in pediatric acute leukemia with "very high" leukocytosis (VHL) prior to rasburicase availability and without leukopheresis. From Jun 2003 through Dec 2009, 45 out of 457 (10 %) pediatric acute leukemia patients had VHL. Median WBC for acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) patients was 296,500/mm3 (200,000-615,220) and 206,300/mm3 (106,100-541,900) respectively. Laboratory and clinical tumor-lysis-syndrome was seen in 37.7 % and 13.3 % patients respectively; none required dialysis; 6.6 % died due to CNS/pulmonary bleed. Thrombocytopenia <31,000/mm3 was associated with hypocalcemia (p = 0.04) and mortality (p = 0.04), and hypoalbuminemia with kidney dysfunction (p = 0.04). In resource-limited setting, VHL patients with thrombocytopenia may warrant rasburicase with or without leukopheresis, and aggressive platelet support.
