RESUMEN

PURPOSE: Chemotherapy side effects diminish quality of life and can lead to treatment delay. Nausea and vomiting can occur prior to chemotherapy because of classical conditioning. We studied the effects of 20-minute behavioral interventions, administered by oncology nurses, of higher intensity (mindfulness relaxation-MR) or lower intensity (relaxing music-RM), on anticipatory nausea and vomiting (ANV). PATIENTS AND METHODS: Patients undergoing chemotherapy for solid tumors were randomized to MR (N = 160), RM (N = 159), or standard care SC (N = 155). Subjects were mostly female (91.8%) and white (86.1%) with breast cancer (85%). Most patients had early stage disease (Stage I: 26%; II: 52.9%; III: 19%; IV: 0.1%). Anticipatory nausea and vomiting were assessed at the midpoint and end of the chemotherapy course using the Morrow Assessment of Nausea and Emesis (MANE). RESULTS: Compared to SC, there was reduced anticipatory nausea at the midpoint of chemotherapy in those receiving MR (OR 0.44, 95% CI 0.20-0.93) and RM (OR 0.40, 95% CI 0.20-0.93), controlling for age, sex, cancer stage, and emetogenic level of chemotherapy. There was no difference between treatment groups in anticipatory nausea at the end of chemotherapy or in anticipatory vomiting and postchemotherapy nausea and vomiting at either time point. CONCLUSION: A brief nurse-delivered behavioral intervention can reduce midpoint ANV associated with chemotherapy.

RESUMEN

Background In response to the national leucovorin shortage in 2008, our institution adjusted the modified FOLFOX6 (leucovorin, fluorouracil, and oxaliplatin) protocol to utilize a lower dose of leucovorin (20 mg/m2). This adjustment was based on prospective studies suggesting that lower doses of leucovorin may be equally effective in other fluorouracil containing regimens. This retrospective study evaluates outcomes in metastatic colorectal cancer (mCRC) patients treated with low- (20 mg/m2) vs. high-dose (400 mg/m2) leucovorin in the FOLFOX6 regimen for mCRC. Methods This retrospective analysis included consecutive mCRC patients from 2004 to 2011 if they received at least one cycle of modified FOLFOX6 as first line therapy. Patients who received an initial leucovorin dose other than 20 mg/m2 or 400 mg/m2 on their first cycle were excluded. Patient characteristics included demographics, metastatic site at initial diagnosis, and treatment history including chemotherapy and surgery. Primary outcome was date of death or last contact. Cox proportional hazards regression analysis and Kaplan-Meier survival curves were utilized to evaluate the effect of leucovorin dose on overall survival. Log-rank tests were used to compare median survival times by dose group. Results Of the 93 mCRC patients who received first line modified FOLFOX6, leucovorin 400 mg/m2 was administered to 47 (51%) patients and 20 mg/m2 to 46 (49%) patients. There were no differences of baseline characteristics between the groups with exception of primary site of cancer ( p = 0.038). The overall survival time was 22.5 months (95% CI 16.6-29.6). The median survival time in the leucovorin 400 mg/m2 group was 23.1 months (95% CI 16.2-35.7) compared to leucovorin 20 mg/m2 which was 20.5 months (95% CI 14.2-34.2); p = 0.573. The median survival times in patients with one versus two or more sites with metastasis were statistically different (26.9 vs. 16.2 months, p = 0.009). Metastatic site removal or ablation showed differences in the median survival, 34.2 months (95% CI 20.8-50.9) vs. 16.6 months (95% CI 14.1-23.6) without metastatic disease removal ( p = 0.004). The odds of dying for patients with two metastatic sites was higher compared with the odds of those patients with one site, HR 1.8 (95% CI 1.08-3.0). Patients without metastatic site removal or ablation had higher odds of dying compared to those patients without this procedure, HR 0.47 (95% CI 0.27-0.81). Conclusion In this single center retrospective study, there was no difference in overall survival for mCRC patients treated with first line FOLFOX6 with low- vs. high-dose leucovorin.

RESUMEN

PURPOSE: Calcium aluminosilicate clay (CASAD) is a naturally occurring clay that serves as a cation exchange absorbent. We hypothesized that oral administration of CASAD would reduce the rate of grade 3/4 diarrhea associated with irinotecan use for metastatic colorectal cancer (CRC) by adsorbing the SN-38 metabolite. METHODS: Patients receiving irinotecan-based chemotherapy were randomized equally between CASAD and placebo arms in this multicenter trial in order to assess differences in the proportions of patients with grade 3/4 diarrhea within 6 weeks. Additionally, we compared symptom severity between the two arms using the M.D. Anderson Symptom Inventory. RESULTS: Between May 2009 and May 2012, 100 patients were enrolled. In evaluable patients, 7 of 43 (16 %) on the CASAD arm compared to 3 of 32 (9 %) on the placebo arm experienced grade 3/4 diarrhea (P = 0.70). The rate of any diarrhea among all patients was similar (CASAD arm, 64 % vs. placebo arm, 70 %). The rate of study dropout was 14 % in the CASAD arm and 38 % in the placebo arm (P = 0.01). No differences were found in symptom severity, individual symptom items, and in serious adverse events between the two arms. CONCLUSION: Compared to placebo, CASAD use was safe but ineffective in preventing diarrhea in metastatic CRC patients treated with irinotecan-containing chemotherapy regimens. There were no distinct signals in terms of patient symptoms between arms, but there was significantly more patient dropout in the placebo arm. Future CASAD trials will focus on the active treatment of diarrhea.
