Population-based cancer staging for oesophageal, gastric, and pancreatic cancer 2012-2014: International Cancer Benchmarking Partnership SurvMark-2.

Int J Cancer 2021 May 14. Epub 2021 May 14.

Cancer Surveillance Branch, International Agency for Research on Cancer, Lyon, France.

Cancer stage at diagnosis is important information for management and treatment of individual patients as well as in epidemiological studies to evaluate effectiveness of health care system in managing cancer patients. Population-based studies to examine international disparities on cancer survival by stage, however, has been challenging due to the lack of international standardization on recording stage information and variation in stage completeness across regions and countries. The International Cancer Benchmarking Partnership (ICBP) previously assessed the availability and comparability of staging information for colorectal, lung, female breast, and ovarian cancers.

Development and comparison of novel bioluminescent mouse models of pancreatic neuroendocrine neoplasm metastasis.

Sci Rep 2021 May 13;11(1):10252. Epub 2021 May 13.

Department of Neuroscience and Pharmacology, University of Iowa, 2-570 Bowen Science Building, 51 Newton Road, Iowa City, IA, 52242, USA.

Pancreatic neuroendocrine neoplasms (pNENs) are slow growing cancers of increasing incidence that lack effective treatments once they become metastatic. Unfortunately, nearly half of pNEN patients present with metastatic liver tumors at diagnosis and current therapies fail to improve overall survival. Pre-clinical models of pNEN metastasis are needed to advance our understanding of the mechanisms driving the metastatic process and for the development of novel, targeted therapeutic interventions.

Differentiating malignant and benign necrotic lung lesions using kVp-switching dual-energy spectral computed tomography.

BMC Med Imaging 2021 May 13;21(1):81. Epub 2021 May 13.

Department of Radiology, University of Chinese Academy of Sciences Chongqing Renji Hospital (Fifth People's Hospital of Chongqing), No. 24 Renji Road, Nan'an District, Chongqing, China.

Background: Necrotic pulmonary lesions manifest as relatively low-density internally on contrast-enhanced computed tomography (CT). However, using CT to differentiate malignant and benign necrotic pulmonary lesions is challenging, as these lesions have similar peripheral enhancement. With the introduction of dual-energy spectral CT (DESCT), more quantitative parameters can be obtained and the ability to differentiate material compositions has been highly promoted. Read More

[Strategy with Immune Checkpoint Inhibitors for ES‒SCLC].

Gan To Kagaku Ryoho 2021 Apr;48(4):493-498

Division of Medical Oncology, Dept. of Internal Medicine, Teikyo University School of Medicine.

As a treatment strategy for various carcinoma, immune checkpoint inhibitors(ICIs)can prolong overall survival with ICI monotherapy, ICIs combination therapy, or chemotherapy and ICI combination therapy. It has been validated in clinical trials and is recognized as a key drug in the treatment of cancer. In two large phase Ⅲ trials(IMpower133 and CASPIAN), the strategy of anti PD‒L1 antibody, such as atezolizumab and durvalumab, with chemotherapy was prolonged overall survival compared with the chemotherapy alone in extensive stage small cell lung cancer.

[Comprehensive Genomic Analysis for Small Cell Lung Cancer].

Gan To Kagaku Ryoho 2021 Apr;48(4):476-485

Dept. of Thoracic Oncology, National Cancer Center Hospital East.

Small cell lung cancer(SCLC)is one of the histological types of lung cancer showing the worst prognosis, and is often diagnosed as an inoperable advanced stage disease. Recently, several comprehensive genomic analyses for SCLC have shown that inactivating mutations of tumor suppressor genes such as TP53 and RB1 and MYC family gene amplifications are involved in the development and progression of SCLC. However, actionable gene alterations for targeted therapies have not yet been identified, and there has been no significant advance in the development of targeted therapies for SCLC. Read More

Gan To Kagaku Ryoho 2021 Apr;48(4):472-475

Dept. of Diagnostic Pathology, National Cancer Center Hospital.

The name of small cell carcinoma is becoming unified with neuroendocrine carcinoma in many other cancers except lung cancer, and following this trend, small cell carcinoma of the lung categorized into a subtype under neuroendocrine carcinoma in the 2015 WHO classification. However, small cell carcinoma has been retained and remain as a distinct entity. In this article, I introduced the history and current concept of small cell lung cancer classification, as well as the molecular biological classification of small cell lung cancer based on 4 definitive molecules, ASCL1, NEUROD1, YAP1, and POU2F3, proposed in 2019.
