Results of scalp cooling during anthracycline containing chemotherapy depend on scalp skin temperature.

OBJECTIVES: The success of scalp cooling in preventing or reducing chemotherapy induced alopecia (CIA) is highly variable between patients undergoing similar chemotherapy regimens. A decrease of the scalp skin temperature seems to be an important factor, but data on the optimum temperature reached by scalp cooling to prevent CIA are lacking. This study investigated the relation between scalp skin temperature and its efficacy to prevent CIA. MATERIALS AND METHODS: In this explorative study, scalp skin temperature was measured during scalp cooling in 62 breast cancer patients undergoing up to six cycles of anthracycline containing chemotherapy. Scalp skin temperature was measured by using two thermocouples at both temporal sides of the head. The primary end-point was the need for a wig or other head covering. RESULTS: Maximal cooling was reached after 45 min and was continued for 90 min after chemotherapy infusion. The scalp skin temperature after 45 min cooling varied from 10 °C to 31 °C, resulting in a mean scalp skin temperature of 19 °C (SEM: 0,4). Intrapersonal scalp skin temperatures during cooling were consistent for each chemotherapy cycle (ANOVA: P = 0,855). Thirteen out of 62 patients (21%) did not require a wig or other head covering. They appeared to have a significantly lower mean scalp skin temperature (18 °C; SEM: 0,7) compared to patients with alopecia (20 °C; SEM: 0,5) (P = 0,01). CONCLUSION: The efficacy of scalp cooling during chemotherapy is temperature dependent. A precise cut-off point could not be detected, but the best results seem to be obtained when the scalp temperature decreases below 18 °C. TRIALREGISTER. NL NTR NUMBER: 3082.

Measurement of chemotherapy-induced alopecia-time to change.

Data on chemotherapy-induced alopecia (CIA) as a side effect of cancer treatment are scarce. CIA is given minimal attention in clinical trials and in the literature. However, when asking the patients with cancer for their opinion, CIA appears to have a major impact, particularly on body image and quality of life. Currently, there is no commonly used measure to evaluate CIA; It is time to improve the management and measurement of CIA.

Scalp cooling to prevent alopecia after chemotherapy can be considered safe in patients with breast cancer.

With modern scalp cooling equipment cytotoxic damage of hair root cells can be prevented in half of the patients with cancer at high risk of alopecia. However, traditionally doubt has existed whether scalp cooling might facilitate hiding and disseminating scalp skin metastases and thus decrease survival. We discuss this risk using frequency data on metastases in breast cancer from observational and autopsy studies and the Munich cancer registry. They showed the incidence of scalp skin metastases to be very low and not differ between scalp-cooled (0.04-1%) and non scalp-cooled (0.03-3%) patients with breast cancer and in need of chemotherapy. We found it rather unlikely that the incidence of scalp skin metastases might increase at all after scalp cooling, whereas a very small proportion of patients receiving chemotherapy are at risk to develop metastases at this site. Scalp cooling can thus safely be offered to patients treated with alopecia-inducing chemotherapy.

Impact of scalp cooling on chemotherapy-induced alopecia, wig use and hair growth of patients with cancer.

INTRODUCTION: Cytotoxic therapy for patients with cancer frequently induces reversible, but long-lasting alopecia which might be prevented by scalp cooling. This study evaluates the effectiveness of scalp cooling with respect to the severity of chemotherapy-induced alopecia (CIA) and the purchase and use of wigs and head covers. MATERIALS AND METHODS: In this observational study, scalp-cooled patients (n = 160) were compared with non scalp-cooled patients (n = 86) with several types of cancer. Patients were enrolled in 15, mostly general hospitals prior to taxane and/or anthracycline-based chemotherapy. Patients completed four questionnaires between the start and one year after the last chemotherapy. RESULTS: Severity of CIA, and purchasing and actually wearing wigs and head covers were significantly lower among scalp-cooled than non scalp-cooled patients. Overall, scalp cooling reduced the use of wigs and head covers by 40%. Among 84 scalp-cooled patients who purchased a wig (53%), only 52 patients actually wore it (62%), and they just wore it intensively (86% daily) for less than six months (80%). Especially young patients camouflaged CIA with a head cover instead of a wig. DISCUSSION: The relatively long duration of CIA, the wish of many patients to camouflage or rather prevent it and the 40% reduction for head covering by scalp cooling, makes it a worthwhile supportive intervention. However, (cost-) effectiveness can be improved. Many scalp-cooled patients purchased a wig unnecessarily.

Short post-infusion scalp cooling time in the prevention of docetaxel-induced alopecia.

PURPOSE: The patient impact of chemotherapy-induced alopecia (CIA) is high. Scalp cooling is applied to reduce CIA. The potential optimum post-infusion cooling times (PICTs) are currently unknown. METHODS: Scalp cooling was applied in 53 patients receiving docetaxel chemotherapy with 90-min PICT (observational part). Also 15 non-scalp-cooled patients were included. If hair preservation was observed in >80 % of the patients, randomisation between 45 and 90-min PICT was planned. Patients reported tolerance of scalp cooling and use of head covering. RESULTS: Observational study: 81 % of scalp-cooled patients did not require head covering versus 27 % of non-scalp-cooled patients. Randomised study: 79 % of 38 patients with 90-min PICT did not need head covering versus 95 % of 38 patients with 45-min PICT (p = 0.04). Scalp cooling was very well tolerated (visual analogue scale = 79). CONCLUSION: A 45-min PICT can be recommended in 3-weekly docetaxel regimens with a dose of 75 or 100 mg/m(2), administered in 60 min. The shorter PICT is a major advantage in time investment for patients. Patients (women and men) who receive docetaxel, except combined with doxorubicin and cyclophosphamide (taxotere, adriamycin and cyclophosphamide (TAC)) should be informed about the protective effect and high tolerability of scalp cooling in avoiding CIA.

[Compliance with the breast cancer guidelines in the region of the Comprehensive Cancer Centre South, 20031/'04]. / Naleving van mammacarcinoom-richtlijnen in de regio van het Integraal Kankercentrum Zuid, 2003/'04.

OBJECTIVE: To examine the level of compliance with the NABON-guidelines (i.e. breast cancer consensus recommendations) issued in 1999 with particular regard to the diagnostics and treatment of breast cancer in hospitals in the region covered by the Comprehensive Cancer Centre South (covering the Noord-Brabant and Noord-Limburg areas in the Netherlands). DESIGN: Retrospective, descriptive. METHOD: Using the Cancer Registry, the average number ofbreast cancer patients in 16 general hospital locations in the region covered by the Comprehensive Cancer Centre South was determined. Then, from I July 2003 to 30 June 2004, at each hospital location, all successive patients in whom carcinoma of the breast (invasive or in situ) had been diagnosed were included until one-third of the annual total was reached. Data from the medical-case notes of these patients were collected in order to examine to what extent the hospital locations had complied with the NABON-norms. RESULTS: A total of 581 breast cancer patients were included. In general the diagnostics and treatment complied with the consensus recommendations in the NABON-policy document. Improvements were mainly indicated in the area of logistics. One hospital met the guideline's recommendation that in 90% of cases, the pathology department should ensure that the results ofa histological needle-biopsy are available within 2 days of the biopsy being carried out. In 62% of patients, surgery was performed within 3 weeks of the necessity of an operation being confirmed, although the target norm was 90%. The interval between the last operation and the start of radiotherapy treatment was 44 instead of the proposed 28 days. Inter-hospital differences in diagnostics were seen mainly in the application of sentinel-node biopsy (34-95%). Furthermore, broad diversity was observed in the percentage of patients treated in the proposed space oftime between pathology result and initial surgery (3-87%) and between the last operation and start ofradiotherapy (0-46%) or chemotherapy (0-100%).
