BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a major dose-limiting toxicity of cytostatics. With improved survival among cancer patients, CIPN may have a major impact on quality of life (QoL) of cancer survivors. OBJECTIVE: To determine the occurrence of CIPN induced by oxaliplatin and taxanes and its impact on QoL median 6 months after chemotherapy. METHODS: All patients who received their last treatment with oxaliplatin or taxanes in 2 consecutive years in the Máxima Medical Centre, the Netherlands, were eligible for the study. Neurotoxicity and its effect on QoL was assessed with the recently developed Chemotherapy Induced Neurotoxicity Questionnaire (CINQ) and the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) median 6 months after cessation of therapy. RESULTS: Of the 58 eligible patients, 43 (74.1%) completed the questionnaire. After a median follow-up of 6.5 months after cessation of therapy, most of the patients experienced neurotoxicity in the upper and lower extremities (78.8% and 89.7%, respectively). Overall, the most-reported complaints included numbness and tingling in hands as well as feet, suffering from cold feet, and trouble distinguishing objects in the hands. Housekeeping difficulties were reported in 12.8% of patients, and 20.5% of patients became more dependent on others because of the neurotoxicity. Overall, QoL was negatively affected by the impact of CIPN in 48.6% of patients. LIMITATIONS: Due to the small sample size selection bias cannot be ruled out and no data about CIPN during treatment were available. Conclusions After a median follow-up of 6.5 months after cessation of therapy with oxaliplatin or taxanes, CIPN is common and leads to impairment in patient QoL. More research is needed to assess the impact of neurotoxicity on QoL. CONCLUSIONS: After a median follow-up of 6.5 months after cessation of therapy with oxaliplatin or taxanes, CIPN is common and leads to impairment in patient QoL. More research is needed to assess the impact of neurotoxicity on QoL.

We determined whether progression-free survival (PFS) in metastatic breast cancer (MBC) patients receiving everolimus plus exemestane (EVE/EXE) varies depending on circulating tumour DNA (ctDNA) characteristics. Baseline plasma cell-free DNA (cfDNA) from 164 postmenopausal women with ER-positive, HER2-negative MBC refractory to a nonsteroidal aromatase inhibitor and treated with standard EVE/EXE (Everolimus Biomarker Study, Eudract 2013-004120-11) was characterised for 10 relevant breast cancer genes by next-generation sequencing with molecular barcoding. ctDNA molecule numbers, number of mutations and specific variants were related with PFS and overall survival (OS). Missense hotspot mutations in cfDNA were detected in 125 patients. The median of 54 ctDNA molecules per mL plasma distinguished patients with high and low/no ctDNA load. Patients with low/no ctDNA load (N = 102) showed longer median PFS of 5.7 months (P = 0.006) and OS of 124.8 months (P = 0.008) than patients with high ctDNA load (N = 62; 4.4 months and 107.7 months, respectively) in multivariate analyses. Patients with < 3 specific mutations (N = 135) had longer median PFS of 5.4 months compared to those with ≥ 3 mutations (3.4 months; P < 0.001). In conclusion, MBC patients with low/no ctDNA load or < 3 hotspot mutations experience longer PFS while treated with EVE/EXE.

Objective:Individuals with cancer experience the impact of chemotherapy on hair loss in different ways. The aim of this pilot study was to explore patients' experiences of alopecia through patients' drawings.Methods:Fifteen female patients diagnosed with cancer and treated with chemotherapy were recruited at the oncological day-care unit of a teaching hospital in the Netherlands. Participants completed a semi-structured interview about alopecia. They drew their head and hair before and during chemotherapy and completed the Brief Illness Perception Questionnaire (B-IPQ).Results:The drawings revealed predominantly physical effects, rather than emotions. Emotions were evident in the text that patients wrote under the drawings and in the B-IPQ open question about the perceived consequences of alopecia. The overall impact of alopecia that emerged from the drawings and the B-IPQ corresponded to the information retrieved from the interviews, namely disappointment, insecurity, sadness, and confrontation.Conclusions:Drawings expose cognitive and emotional responses to alopecia that may be relatively unexplored when using traditional assessment methods such as questionnaires or interviews. In future research, the drawing instructions need to be more specifically focused on feelings in order to better capture emotional reactions to hair loss.

1028 Background: The role of bisphosphonates when added to the neoadjuvant treatment of BC in enhancing the efficacy of therapy is still unknown. Methods: NEOZOTAC is a national, multicenter, randomized study comparing the efficacy of TAC (docetaxel, Adriamycin and cyclophosphamide i.v.) CT followed by G-CSF on day 2 with or without ZA 4 mg i.v. ,q 3 weeks in patients (pts) with stage II/III, measurable, HER2-negative BC and absence of prior bisphosphonate usage. The primary endpoint is the pathologic complete response (pCR) rate in the resection specimen and positive lymph nodes. 228 pts are needed to show an improvement of the pCR rates from 17% to 34% in the experimental arm using a 5% significance level based on the two-sided Fisher’s exact test with a power of 80%. Randomization was done by using the Pocock’s minimisation technique stratified by cT, cN and estrogen receptor status. pCR rate was analyzed using the Cochran-Mantel-Haenszel test, adjusting for the stratification factors. Analysis was based on intent-to-treat. An unplanned subgroup analysis of postmenopausal women (PMW; FSH &gt;20 and estradiol &lt;110) and baseline vitamin D levels was performed. Results: From July 2010 to April 2012, 250 patients from 25 participating sites were randomized. Pathologic response data of 228 patients are currently available. pCR rate did not differ between the two study arms (17% vs 16%, p = 0.81). However, a trend in benefit in favor of ZA was observed in PMW (18% vs 11%, OR 1.90, 95% C.I. 0.52 – 6.88). Patients with severe vitamin D insufficiency (&lt;25 nmol/L) seemed to respond worse to CT numerically (6% vs. 18%). At ASCO pCR and clinical response data of all patients will be reported. Conclusions: Previously, we have shown that adding ZA to neoadjuvant CT is safe with good compliance.In this study, treatment with ZA did not result in a pCR benefit in the total study population. However our findings suggest that addition of ZA to neoadjuvant CT might be effective for enhancing response in PMW with BC. Clinical trial information: NCT01099436.
