Cyclin D1 IHC in metastatic NPC clinical samples. (a) Cyclin D1 expression in a liver and a lung metastasized NPC patients. The Kaplan-Meier survival curves of the NPC patients classified by the (b) intensity and (c) percentage of positive cells in cyclin D1 IHC staining. A 46 year-old NPC patient with T4N2M0 (stage IVa), also a hepatitis B virus carrier, received concurrent chemoradiotherapy (CCRT) for local disease control. Liver metastasis (cyclin D1 staining, in Fig. 7a) was detected 9 months later and five different lines of palliative chemotherapy prescribed. Finally, the patient received palbociclib (PAL) as salvage treatment at Johns Hopkins Medicine, Singapore. (d) Plasma EBV DNA load reflecting the clinical treatment response of the patient was decreased after treatment with PAL. (e) Whole-body tumor scan before and after PAL treatment at 2-month intervals revealed stable disease. Abbreviations: PULB, (cisplatin, tegafur/uracil, leucovorin, and bleomycin); UFT, (tegafur/uracil); G + P, (gemcitabine + cisplatin); T + P, (docetaxel + cisplatin)
