    Notes: Abstract Ewing's sarcoma of the pelvic bones was diagnosed in a 21-year childbearing woman, raising major medical and ethical problems. The diagnostic and therapeutic approaches during the sixth month of gestation were tailored in order to cure the patient and avoid unnecessary toxicity to the fetus. Ancillary tests included ultrasound and MRI studies of the pelvis. Ifosfamide and adriamycin, premedicated by granisetron, were administered during gestation, and were found to be safe. Cesarean section was the preferred way of delivery since the tumor involved the pelvic bones. The outcome was a disease-free patient and a small healthy baby who is now two years of age.

    Notes: Abstract Purpose: The safety and efficacy of a docetaxel-cisplatin combination (DC) were evaluated in 41 patients pretreated for advanced breast cancer (ABC). Patients and methods: The first 2 patients received 85 mg/m2 docetaxel followed, 6 hours later, by 80 mg/m2 cisplatin repeated every 3 weeks; the other 39 received the same regimen, with 75 mg/m2 docetaxel. Appropriate dose reductions but no growth factor administration were planned. Treatment was continued until disease progression, excessive toxicity or patient refusal. Results: A total of 223 chemotherapy courses were administered, with a median of 6 cycles per patient (range 1–8). All 41 patients were assessed for toxicity using NCI-CTC. Severe neutropenia was experienced by 38 patients (93%) (11 at grade 3, 27 at grade 4, 10 with febrile neutropenia). There was one death due to neutropenic septic shock. Grade 3 thrombocytopenia occurred in three patients (7%). Five patients (12%) had grade 2 neurosensory toxicity, two (5%) experiencing partial hearing loss. Grade 3 fluid retention occurred in three patients (7%). Of 38 anthracycline-resistant patients, 33 were evaluable for response. Two had a complete response (CR) and ten a partial response (PR), giving an objective response rate of 36%, (95% CI: 20%–55%). Stable disease (SD) was observed in 14 patients (42%), 7 (21%) had progressive disease (PD). Among the three non-resistant patients, two PRs and one SD were observed. Median duration of response was 29 weeks (range 18–70), median time to progression 21 weeks (4–70), and median overall survival 50 weeks (4–104+). Conclusions: This DC regimen is active, with an acceptable safety profile in anthracycline-resistant ABC patients. Its place as a second-line treatment alternative to docetaxel alone or to other second-line combination regimens remains to be determined.

    Description: BACKGROUND Tyrosine kinase inhibitors (TKIs) have improved the outcome of patients with gastrointestinal stromal tumors (GISTs), but most patients eventually develop resistance and progress. Dasatinib is a potent inhibitor of BCR-ABL, KIT, and SRC family kinases as well as imatinib-resistant cells. In GISTs, response evaluation is routinely done using computed tomography (CT) and 18 F-fluorodeoxyglucose positron emission tomography coupled to CT (FDG-PET/CT) for early response assessment and outcome prediction. METHODS This was a 2-stage, phase 2 trial investigating dasatinib 2 × 70 mg per day in patients with histologically proven, TKI-naïve, FDG-PET/CT-positive GIST. The primary endpoint was FDG-PET/CT response. RESULTS Of 52 planned patients, 47 were enrolled from January 2008 to November 2011, when the trial was terminated because of slow accrual. In total, 42 patients were eligible. The median patient age was 61 years, 24 patients were men, and 18 were women. Performance status was 0 in 29 patients and 1 in 13 patients. The median follow-up was 67.2 months. Patients went off trial for elective surgery (n = 8), after 26 cycles as per protocol (n = 5), for disease progression (n = 14), for toxicity (n = 7), and for other reasons (n = 5); and 3 patients died (2 had discontinued drug and 1 was still receiving drug). Toxicity was grade 4 in 5% and grade 3 in 48% of patients and was most often gastrointestinal or pulmonary. Dose was interrupted or reduced in 25% of cycles. The FDG-PET/CT response rate (complete plus partial responses) at 4 weeks was 74% (95% confidence interval, 56%-85%; 14 patients had a complete response, 17 had a partial response, 6 had stable disease, 3 had progressive disease, and 2 were not evaluable). The median progression-free survival was 13.6 months, and the median overall survival was not reached. CONCLUSIONS Dasatinib produced high metabolic response rates in TKI-naive patients with FDG-PET/CT-positive GIST. Cancer 2018 . © 2018 American Cancer Society .
