Case ReportsBortezomib-induced pneumonitis during bortezomib retreatment in multiple myeloma.
Bortezomib is a proteasome inhibitor and is active against multiple myeloma. Most toxicities associated with bortezomib are mild to moderate and manageable; however, bortezomib-induced pneumonitis has been reported in some multiple myeloma cases. Bortezomib-induced pneumonitis was reported to occur relatively soon after the first administration of bortezomib. ⋯ His bortezomib-induced pneumonitis responded to steroid therapy and his respiratory symptoms disappeared. This is the first report in which bortezomib-induced pneumonitis occurred during bortezomib retreatment for relapsed multiple myeloma. Careful management is needed during bortezomib retreatment, even after the previous course of bortezomib was administered safely.

Survival benefit of post-mastectomy radiotherapy in breast carcinoma patients with T1-2 tumor and 1-3 axillary lymph node(s) metastasis.
To investigate the role of post-mastectomy radiotherapy in breast carcinoma patients with a tumor size of 5 cm or smaller (T1-2) and 1-3 axillary lymph node(s) metastasis (N1). ⋯ Post-mastectomy radiotherapy is beneficial in reducing the locoregional recurrence risk in T1N1 breast carcinoma patients with a lymph node ratio of >0.25 and in T2N1 breast carcinoma patients with a lymph node ratio of >0.08. In patients with a lymph node ratio equal to or less than these ratios, post-mastectomy radiotherapy could be omitted to avoid radiotherapy-related risks.
