Résumé
Cyclin-dependent kinases 4/6 (CDK4/6) inhibitors are anti-tumor agents for the treatment of hormone receptor-positive breast cancer. Palbociclib, abemaciclib and dalpiciclib have been approved for the treatment of breast cancer in China. Common adverse effects of CDK4/6 inhibitors include bone marrow suppression, gastrointestinal toxicities, liver dysfunction, and skin or subcutaneous tissue adverse reactions (AEs). The Breast Cancer Expert Group of Chinese Society of Clinical Oncology (CSCO) summarized the incidence, clinical manifestations, and grading of the AEs. This expert consensus reports measures of AE management on the basis of experience of clinical practice and the latest advances worldwide, aiming to guide clinical practice by the way of managing AE and help to choose the best treatment regimen.

<p><b>OBJECTIVE</b>To investigate the prognostic predictors of nasal NK/T cell lymphoma.</p><p><b>METHODS</b>The clinicopathologic feature data of 61 patients with nasal NK/T cell lymphoma proven by pathological examination from Jan. 1997 to Jan. 2005 were collected. Expression of survivin, CD44, nm23, p53, Ki-67, MDR-1 and CD95 was detected by immunohistochemical staining in 30 patients with available histologic specimens. The correlation between these factors and prognosis were analyzed.</p><p><b>RESULTS</b>In univariate analysis, performance status, LDH level, clinical stage, initial treatment response, CD56, Ki-67 and CD95 were found to be the prognostic factors associated with time to progression (TTP) in nasal NK/T cell lymphoma, while the performance status, B symptoms, LDH level, initial treatment response, Ki-67 and CD95 were demonstrated as prognostic factors related to overall survival. In multivariate analysis, clinical stage, initial treatment response and performance status were independent prognostic factors for TTP, while the latter two factors were independent prognostic factors of overall survival.</p><p><b>CONCLUSION</b>Clinical stage and initial treatment response, and performance status are found to be independent prognostic factors for TTP, whereas the latter two factors are demonstrated as independent prognostic factors of the overall survival. Overexpression of Ki-67 may be an unfavorable prognostic factor, but overexpression of CD95 may be a favorable one.</p>
