PurposeMild-to-moderate bone pain is a commonly reported adverse event (AE) associated with pegfilgrastim. We evaluated the effect of prophylactic naproxen or loratadine vs no prophylactic treatment on pegfilgrastim-associated bone pain.MethodsIn this open-label study (NCT01712009), women ≥ 18 years of age with newly diagnosed stage I–III breast cancer and an ECOG performance status ≤ 2 who were planning ≥ 4 cycles of adjuvant or neoadjuvant chemotherapy with pegfilgrastim support starting in cycle 1 were randomized 1:1:1 to receive naproxen, loratadine, or no treatment to prevent pegfilgrastim-associated bone pain. The primary endpoint was all-grade bone pain in cycle 1 from AE reporting. Secondary endpoints included bone pain in cycles 2–4 and across all cycles from AE reporting and patient-reported bone pain by cycle and across all cycles.ResultsSix hundred patients were enrolled. Most patients (83.0%) were white, and mean (SD) age was 54.2 (11.1) years. The percentage of patients with all-grade bone pain in cycle 1 from AE reporting in the naproxen, loratadine, and no prophylaxis groups was 40.3, 42.5, and 46.6%, respectively; differences between the treatment groups were not statistically significant. Maximum, mean, and area under the curve for patient-reported bone pain were consistently lower in the naproxen and loratadine groups than in the no prophylaxis group; some of these differences were significant. Loratadine was associated with fewer treatment-related AEs and discontinuations than naproxen.ConclusionsGiven its tolerability, its ease of administration, and its potential benefit, treatment with loratadine should be considered to help prevent bone pain in patients receiving chemotherapy and pegfilgrastim.Clinical trial registration

PLD plus carboplatin has moderate antitumor activity and excellent tolerability. Herceptin and PLD plus carboplatin in HER2-positive patients have antitumor activity without significant cardiac toxicity. Toxicity results suggest that PLD can be combined with Herceptin with minimal cardiac toxicity.
Fifteen patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck received a 5 day continuous I.V. infusion of 6-thioguanine repeated every five weeks. Dose limiting toxicity was primarily hematological with grade III/IV leucopenia and thrombocytopenia seen in seven patients. Nausea and vomiting was moderate and well controlled with antiemetics. No complete or partial responses were observed, with a median time to progression of 58 days and a median survival of 227+ days for the entire group. Based on these results we do not recommend I.V. 6-thioguanine for the treatment of this disease.
There are less data available on the effect of the ACA on breast cancer care beyond the screening level. A retrospective review at participating iCaRe2/BCCR institutions was completed before and after ACA. Post‐ACA, patients were older, more urban, and more likely to be insured through Medicaid. Increased imaging use was noted post‐ACA. These patients were less likely to be diagnosed with late‐stage cancers, received fewer mastectomies, and were more likely to have radiation.
12107 Background: Chemotherapy-induced nausea and vomiting (CINV), a major adverse effect of cancer treatment, can attenuate life quality. Multiple international antiemetic guidelines have recommended a 4-drug regimen (corticosteroid, 5-HT3 receptor antagonist, NK-1 receptor antagonist, and the antipsychotic medication olanzapine) for decreasing highly emetogenic CINV. This raised a question regarding whether antiemetic therapy regimens for highly emetogenic chemotherapy could be de-intensified, decreasing cost and side effects from anti-emetogenic agents. Methods: Study A221602 was developed to compare two olanzapine-containing antiemetic regimens, one with the use of an NK-1 receptor antagonist (aprepitant or fosaprepitant) and one without. Patients (pts) received intravenous highly emetogenic chemotherapy as either 1) cisplatin, given on one day, at a dose of ≥ 70 mg/m2, with or without other chemotherapy agent(s) or 2) doxorubicin (60 mg/m2) plus cyclophosphamide (600 mg/m2) on one day. Pts in both arms received 1) a 5-HT3 receptor antagonist (palonosetron 0.25 mg IV or ondansetron 8-16 mg IV or 16-24 mg PO,) on day one, 2) dexamethasone (12 mg PO, day one followed by 8 mg PO, days 2-4), and 3) olanzapine (10 mg/day PO, days 1 to 4). On Day 1, all agents were given prior to chemotherapy, with the exception that olanzapine could be taken prior to chemotherapy or at bedtime. Additionally, pts were randomized to receive an NK-1 receptor antagonist (fosaprepitant 150 mg IV or aprepitant 130 mg IV; 346 pts) or a matching placebo (344 pts). The primary objective was to compare the proportion of patients with no nausea for 5 days following receipt of their chemotherapy between the two study arms. Results: While there was no suggestion of outcome differences on day 1 between the two study arms, fewer pts (7.4%; upper limit of the 95% confidence interval was 13.5%) without NK-1 receptor antagonists were without nausea for the complete 5-day study period. Conclusions: Per the study design, created to exclude a 10% benefit for NK-1 receptor antagonists, the results did not provide sufficient evidence to reject the hypothesis that the 4-drug regimen was superior to the protocol 3-drug regimen (p=0.24).
