ABSTRACT

OBJECTIVE: The present study aimed to retrospectively examine the effectiveness of mandatory dexamethasone (m-DEX) strictly monitored by pharmacists collaborating with medical physicians and nurses for reducing pemetrexed (PEM)-induced skin rash in patients with non-squamous non-small-cell lung cancer (ns-NSCLC). METHODS: We compared the rash grades during the first cycle of PEM-containing regimens between patients who received m-DEX after February 2012 and those who received dexamethasone (DEX) at their physician's discretion (d-DEX) before January 2012. RESULTS: Of 163 patients with ns-NSCLC included in this study, 89 received d-DEX and 74 received m-DEX. The mean DEX doses the night before and the day after PEM administration were significantly higher in the m-DEX group than in the d-DEX group. The frequency of grade ≥2 skin rash was significantly lower in the m-DEX group than in the d-DEX group. CONCLUSIONS: The use of m-DEX strictly monitored by pharmacists might significantly reduce the severity of PEM-induced skin rash.

ABSTRACT

Afatinib is a newly approved second-generation epidermal growth factor receptor-tyrosine kinase inhibito r(EGFR-TKI). Afatinib has been shown to prolongthe overall survival of patients with non-small cell lungcancer (NSCLC) with EGFR mutations compared with the standard chemotherapy. However, Grade 3 or 4 toxicities, includingdiarrhea, rash, paronychia, and stomatitis, have been observed more frequently in patients treated with afatinib than in those treated with first-generation EGFR-TKIs. Accordingly, our institution developed an afatinib clinical pathway (the afatinib pathway), which was designed by certified nurses, medical physicians, and certified pharmacists, with the goal of reducing the severity of diarrhea and rash that occur most frequently duringthe 28-day introductory period of afatinib treatment. Between May and October 2014, afatinib was administered accordingto the afatinib pathway to 14 patients with NSCLC and EGFR mutations. Of these patients, only one (7.1%) experienced Grade 3 diarrhea. No other patient experienced Grade 3 or 4 toxicity. The afatinib pathway was effective in reducingthe severities of the diarrhea and rash duringthe 28-day introductory period of the afatinib treatment. Our implementation of the afatinib pathway could be considered the Japanese style of collaborative drugtherapy management (J-CDTM).

ABSTRACT

Cisplatin (CDDP) is a key drug in the systemic treatment of various solid tumors. Brand-name CDDP may differ across generic formulations considering various clinical parameters. Therefore, in this study, we aimed to assess the safety of a generic CDDP formulation. To compare brand-name CDDP with a generic formulation, the incidence of adverse events, especially renal toxicity, was investigated in 500 patients with thoracic malignancies who received chemotherapy with more than 60 mg/m2 of either brand-name or generic CDDP. We compared the maximum serum creatinine (Cr) level after chemotherapy in the 2 groups. The correlation coefficients between the pretreatment Cr and the maximum Cr after CDDP administration did not differ between brand-name CDDP and generic CDDP (0.610 and 0.644, respectively; p=0.528). Furthermore, the correlation coefficients did not differ in subgroup analysis according to sex or adjuvant therapy. The severity of adverse events was similar in the 2 groups. In conclusion, generic CDDP can safely be used as an alternative to brand-name CDDP in the clinical setting.

ABSTRACT

The anti-receptor activator of nuclear factor-kB ligand (RANKL) antibody denosumab is thought to be useful in the improvement of the quality of life of patients with bone metastasis from thoracic tumors, given the ease of its subcutaneous administration. However, attention has to paid to the onset of hypocalcemia when determining the optimal dosage, especially since data and methods on its prevention are limited. Our project team monitored serum calcium levels in patients receiving denosumab treatment, evaluated methods to supplement calcium and vitamin D in cases of hypocalcemia, and developed an evidence-based common manual. Subsequently, denosumab administration and hypocalcemia were evaluated as per the manual. Grade 3 hypocalcemia was observed in 2 cases before the preparation, with no new cases seen since adopting the new protocol in the manual. We conclude that the development of severe hypocalcemia associated with denosumab treatment can be avoided by prompt management of this condition in the early stages and by adopting measures listed in the practice manual.
