This case is a 56-year-old woman. With multiple bone metastases, she was referred to the Department of Palliative Care on the same day as core needle biopsy had just been performed in the Department of Surgery. Aggressively increased oxycodone was administered to relieve her significantly severe pains by bone metastases. After relief of the pains, cancer chemotherapy of EC and weekly PTX regimens were performed parallel to palliative care. In this case, chemotherapy could be performed after the pains had been sufficiently relieved with closer cooperation between the palliative care doctor and the attending surgeon. It is important for patient-focused medical care to be delivered by both the attending doctor administering cancer treatment and the palliative care doctor working for relief of the symptoms, while they are striving to foster their tie-up.

INTRODUCTION:
The pathophysiology and mechanism of in-stent restenosis (ISR) after implantation of second-generation drug-eluting stents (DESs) are not fully clear. We compared the morphological characteristics of ISR between first- and second-generation DESs using frequency domain optical coherence tomography (OCT).
METHODS:
Patients who underwent follow-up coronary angiography (CAG) after first-generation (CYPHER™ and TAXUS™) and second-generation (Nobori®, PROMUS Element™, Resolute Integrity and XIENCE) DES implantations were examined. ISR was defined as lesions of over 50% diameter stenosis at follow-up CAG. Frequency domain OCT was performed at the time of revascularisation of ISR. Tissue morphology was assessed at minimum lumen area. OCT images of DESs at both early (≤ 1 year) and late (> 1 year) phase follow-up were compared.
RESULTS:
On qualitative OCT assessment, the ratios of homogeneous, layered, heterogeneous without-attenuation and heterogeneous with-attenuation morphologies were 57.1%, 17.1%, 20.0% and 5.7%, respectively, for second-generation DES ISR (n = 35), and 16.7%, 25.0%, 25.0% and 33.3%, respectively, for first-generation DES ISR (n = 36). At late phase follow-up, homogeneous morphology was significantly more common for second-generation DES ISR compared to first-generation DES ISR (first-generation: 8.0% vs. second-generation: 50.0%; p < 0.01) while heterogeneous with-attenuation morphology was significantly more common for first-generation DES ISR (first-generation: 44.0% vs. second-generation: 5.6%; p < 0.01).
CONCLUSION
Homogeneous tissue morphology was more frequently found for second-generation than first-generation DES ISR, especially in the late phase. This suggested that neointimal hyperplasia was the main mechanism in second-generation DES ISR, and that the neointima was stabilised, much like in bare metal stent implantation.
