Updated evidence on oncological outcomes of surgery versus external beam radiotherapy for localized prostate cancer
Radical prostatectomy and external beam radiotherapy are recognized as comparable treatment options for localized prostate cancer. This review summarizes the updated evidence on oncological outcomes of surgery versus radiotherapy.
Rare cancers in Japan: definition, clinical features and future perspectives
This review covers the definition, epidemiology and therapeutic challenges of rare cancers and describes the establishment of the Rare Cancer Center at the National Cancer Center, Japan.
Advance care planning in Asian culture
The advocacy of Advance Care Planning (ACP) is a means to honor patient autonomy. Since most East Asian countries are influenced by the Confucianism and the concept of ``filial piety'', patient autonomy is consequently subordinate to family values and physician authority. The dominance from family members and physicians during a patient's end-of-life decision-making is recognized as a cultural feature in Asia. In order to address this ethical and practical dilemma, the concept of `relational autonomy' and the collectivism paradigm might be ideally used to assist Asian people, especially older adults, to share their preferences on future care and decision-making on certain clinical situations with their families and important others. In this review article, we invited experts in end-of-life care from Hong Kong, Indonesia, Japan, South Korea, Singapore and Taiwan to briefly report the current status of ACP in each country from policy, legal and clinical perspectives.

Central Nervous System
Factors associated with health-related quality of life in patients with glioma: impact of symptoms and implications for rehabilitation
In addition to neurological deficits, symptoms were associated with poor QOL in patients with glioma. This study provided the basis on further investigation of usefulness of symptom evaluation on QOL improvement.
Consecutive single-institution case series of primary central nervous system lymphoma treated by R-MPV or high-dose methotrexate monotherapy
In a retrospective analysis of newly diagnosed primary central nervous system lymphoma treated at a single institution, a higher complete response rate was observed in R-MPV in comparison with HD-MTX monotherapy. Furthermore, R-MPV followed by high-dose cytarabine consolidation seemingly bestowed longer survival.
Epidemiology/Public Health
Cumulative cigarette tar exposure and lung cancer risk among Japanese smokers
This case-control study showed that cumulative tar exposure is a dose-dependent indicator for lung cancer risk, and low-tar exposure was still associated with increased cancer risk.
Head & Neck
Pull-through resection without free-flap reconstruction for lateral wall oropharyngeal cancer
Pull-through resection without reconstruction is more effective and less invasive than conventional open approaches for OPC and a particularly useful option in regions where TORS has not yet become widespread.
Immunology
Clinical significance of tumour mutation burden in immunotherapy across multiple cancer types: an individual meta-analysis
Our comprehensive meta-analysis of 6171 patients demonstrated that patients with higher tumour mutation burden were associated with a reduction of 43% risk of all-cause mortality and 50% risk of disease progression and a higher response rate.
Orthopedics/Sarcoma
Is tumour location a prognostic factor for pharmacological treatment in patients with desmoid-type fibromatosis? a systematic review
According to this systematic review, we weakly recommend that drug treatment can be performed irrespective of the tumour location in patients with extra-abdominal desmoid-type fibromatosis.
Is mutation analysis of β-catenin useful for the diagnosis of desmoid-type fibromatosis? A systematic review
We performed a systematic review to verify the usefulness of CTNNB1 mutation analysis in the diagnosis of DF. It may be useful for the cases that have difficulty in histopathological diagnosis.
Severity of emphysema as a prognosticator of resected early lung cancer: an analysis classified by Goddard score
Pulmonary emphysema with a GS of ≥5 points may be a factor that can influence the prognosis of patients with primary lung cancer.
Wedge resection as an alternative treatment for octogenarian and older patients with early-stage non–small-cell lung cancer
This study provides useful information with which to determine optimal surgical procedures for patients aged ≥80 years. Wedge resection might be an alternative to anatomical resection in such patients.
Tumor Markers
HAGLROS is overexpressed and promotes non-small cell lung cancer migration and invasion
HAGLROS is a kind of long non-coding RNA. We found knockdown of HAGLROS in non-small cell lung cancer cells remarkably suppressed tumour proliferation, migration and invasion. Our results for the first time demonstrated HAGLROS may serve as a target for new therapies in non-small cell lung cancer.
Urology
Prognostic significance of non-urothelial carcinoma of bladder: analysis of nationwide hospital-based cancer registry data in Japan
The prognoses of the patients with pure non-urothelial carcinoma of bladder were worse than those of the patients with pure UC.
Clinical Trial Note
Sublobar resection versus lobectomy for patients with resectable stage I non-small cell lung cancer with idiopathic pulmonary fibrosis: a phase III study evaluating survival (JCOG1708, SURPRISE)
A randomized phase III trial has started in order to confirm the clinical effectiveness of sublobar resection for early NSCLC with idiopathic pulmonary fibrosis comparing with lobectomy.
Cancer Genetics Report
The first case report of polymerase proofreading-associated polyposis in POLD1 variant, c.1433G>A p.S478N, in Japan
We report the first Japanese case of polymerase proofreading-associated polyposis carrying a POLD1 variant.
