Background: Fosaprepitant-associated injection site reaction (ISR) has been reported in patients treated with cisplatin, an irritant drug. We conducted this retrospective study to clarify the incidence and symptoms of fosaprepitant-associated ISR in patients treated with anthracycline.Patients and methods: Fifty six patients receiving 159 injections administering doxorubicin/cyclophosphamide (AC), fluorouracil/epirubicin/cyclophosphamide (FEC), or rituximab/cyclophosphamide/doxorubicin/vincristine/prednisolone (R-)CHOP regimen through a peripheral vein at ambulatory treatment centers reviewed for this study from patients' medical records. Incidence of ISR was compared between 24 patients with fosaprepitant injection (fosaprepitant group) and 32 patients without fosaprepitant (control group). Frequency and symptoms of ISR per injection were also compared between 61 injections with fosaprepitant and 98 injections without fosaprepitant.Results: Both the ISR incidence rate per patient and per injection were significantly higher in the fosaprepitant group than in the control group (67% vs. 16%; P=0.0002, 34% vs. 8.2%; P<0.0001, respectively). By multivariate analysis, fosaprepitant injection was found to be a significant independent variable correlated with ISR risk. Symptoms observed in 61 injections of fosaprepitant were pain (n=14, 23%), erythema (n=10, 16%), swelling (n=6, 10%), and delayed drip infusion (n=6, 10%). After the observation period, no ISR occurred when the administration route was changed to central venous injection or oral aprepitant was administered despite the continuation of chemotherapy.Conclusion: ISR occurred more frequently and severely when fosaprepitant was injected through the peripheral vein in patients treated with anthracyclines compared to those without fosaprepitant.

The patients with primary cutaneous melanoma underwent sentinel node (SN) mapping and biopsy at 25 facilities in Japan by the combination of radiocolloid with gamma probe and dye.

Vitiligo vulgaris is a refractory skin disease. Treatment modalities include topical steroids, phototherapy, suction blister roof grafts and cellular grafting techniques. Adverse effects may occur, however, and some cases remain unresponsive to treatment. To evaluate the efficacy of small (1-mm) punch minigraft therapy in relation to patient age, disease site, disease duration and vitiligo subtype. We used a recently developed disposable 1.0-mm punch apparatus to perform minigraft therapy in 20 patients with either generalized (n = 4), segmental (n = 9) or limited (n = 7) vitiligo, and evaluated the area and rate of repigmentation in relation to patient age, disease site, disease duration and vitiligo subtype. The area of repigmentation was significantly greater in patients with segmental vitiligo (n = 9) than in those with generalized vitiligo (n = 4). Repigmentation covered a broader area and occurred more quickly in patients under 15 years of age than in those over 20 years of age (n = 9). Disease duration did not affect the repigmentation rate. The results of the present study suggest that 1-mm minigrafts are effective for treating patients with vitiligo. Better results occurred in patients under 15 years of age, patients with facial grafts, and patients with segmental and limited subtypes.

Extramammary Paget's disease (EMPD) is one of the cutaneous adenocarcinomas. The effective chemotherapy for advanced EMPD has not been established. This study was designed to evaluate the efficacy of combination 5-fluorouracil (500 mg/body, 7 days/week) and cisplatin (5 mg/body 5 days/week) for invasive EMPD. Seventeen EMPD patients with multiple metastases who visited our dermatology clinic between October 2004 and May 2016 (mean age, 76.9 years; 10 men, seven women) were retrospectively analyzed. Eight EMPD patients underwent low-dose 5-fluorouracil/cisplatin therapy and nine patients chose best supportive care. The average number of treatment cycles was 12.3. All patients had a confirmed response, four (50%) showed a partial response, two (25%) stable disease and two progressive disease. The median times to progression-free and overall survival were 25.0 and 77.4 weeks, respectively. There was no severe (grade 3 and 4) adverse event. Although not significant, the survival of the patients treated with low-dose 5-fluorouracil/cisplatin therapy showed a trend toward improved survival as compared with best supportive care (P = 0.08, log-rank test). This regimen had low risk and relatively high disease control rate, suggesting that this regimen be recommended as one of the treatment options for advanced EMPD.
