Prognosis of lung cancer associated with cystic airspaces: A propensity score matching analysis.

Lung Cancer 2021 Jul 17;159:111-116. Epub 2021 Jul 17.

Department of Thoracic Surgery, Shanghai Pulmonary Hospital, Tongji University, Shanghai 200433, China. Electronic address:

Objective: The association between the morphological characteristics and survival outcome of lung cancer associated with cystic airspaces (LCCAs) is unclear due to rarity of this disease. The current study attempted to compare the survival outcome between LCCAs and non-LCCAs and investigate the correlation between imaging features and prognosis of LCCA.

Neonatal streptozotocin treatment rapidly causes different subtype of hepatocellular carcinoma without persistent hyperglycemia in 4CS mice fed on a normal diet.

Pathol Res Pract 2021 Jul 21;225:153559. Epub 2021 Jul 21.

Department of Pathology and Laboratory Medicine and Institute of Biomedical Sciences, Tokushima University Graduate School, 3-18-15 Kuramoto, Tokushima 770-8503, Japan; Molecular Pathology and Institute of Biomedical Sciences, Tokushima University Graduate School, 3-18-15 Kuramoto, Tokushima 770-8503, Japan. Electronic address:

Although diabetes mellitus (DM) is a well-known risk factor for hepatocellular carcinoma (HCC), the underlying mechanisms have not yet to be defined. We previously reported that DIAR mice fed with standard murine diet developed type 1 diabetes and HCC at age of 16 weeks old with a neonatal streptozotocin treatment (n-STZ). Because DIAR mice did not manifest obesity nor develop steatohepatitis, hyperglycemia with streptozotocin trigger or streptozotocin alone might turn on the hepato-carcinogenesis. Read More

Diffuse bone marrow uptake related to granulocyte colony-stimulating factor-producing maxillary sinus carcinoma on 4-borono-2-F-fluoro-L-phenylalanine positron emission tomography/computed tomography.

World J Nucl Med 2021 Apr-Jun;20(2):188-191. Epub 2020 Oct 23.

Department of Oral and Maxillofacial Surgery, Kochi Medical School, Kochi University, Nangoku, Kochi, Japan.

Granulocyte colony-stimulating factor (G-CSF) can be produced by tumor cells and is known to promote tumor growth, thereby potentially accelerating disease progression. Squamous cell carcinoma (SCC) at maxillary sinus is aggressive growth with poor prognosis. Maxillary sinus carcinomas are rare and can be clinically silent in the early stages or manifest with the same signs and symptoms of more common illnesses, leading to their delayed diagnosis of disease.

Computed Tomography Morphological Classification of Lung Adenocarcinoma and Its Correlation with Epidermal Growth Factor Receptor Mutation Status: A Report of 1075 Cases.

Int J Gen Med 2021 21;14:3687-3698. Epub 2021 Jul 21.

Department of Radiology, University of Chinese Academy of Sciences Chongqing Renji Hospital (Fifth People's Hospital of Chongqing), Chongqing, 400062, People's Republic of China.

Background: Many delayed diagnoses of lung adenocarcinoma (LADC) are identified due to poor understanding of protean imaging findings. Moreover, clarifying the relationship between computed tomography (CT) morphological classification and epidermal growth factor receptor (EGFR) mutations of LADC might inform therapeutic decision-making while obtaining pathological specimens is difficult. Here, we retrospectively analyzed CT manifestations of LADC and investigated the morphological classification of tumors in relation to EGFR mutation status. Read More

Fabrication of a multi-level drug release platform with liposomes, chitooligosaccharides, phospholipids and injectable chitosan hydrogel to enhance anti-tumor effectiveness.

Carbohydr Polym 2021 Oct 10;269:118322. Epub 2021 Jun 10.

Department of Materials Science and Engineering, Institute of Biomedical Engineering, The First Affiliated Hospital, Jinan University, Guangzhou 510632, PR China.

Some anti-cancer drugs have poor solubility and availability, and are easily eliminated by rapid metabolism in vivo. To fix the drugs at the administration site and delay their release, a release platform with multi-level and multi-function was designed. The results showed that the curcumin (Cur) loaded liposomes ([email protected]) were coated sequentially with positive Chitooligosaccharides ([email protected]) and negative phospholipids ([email protected]), to enhance water solubility, encapsulation efficiency, and delayed the release of the Cur, stability and cell intake of the liposomes, and the bioactivity of the system.

Cell Prolif 2021 Jul 26:e13102. Epub 2021 Jul 26.

Division of Regenerative Biology, School of Biomedical Sciences, University of Western Australia, Perth, WA, Australia.

Osteosarcoma (OS) is the most common primary malignant bone tumour with a peak in incidence during adolescence. Delayed patient presentation and diagnosis is common with approximately 15% of OS patients presenting with metastatic disease at initial diagnosis. With the introduction of neoadjuvant chemotherapy in the 1970s, disease prognosis improved from 17% to 60%-70% 5-year survival, but outcomes have not significantly improved since then. Read More

Undiagnosed Endoscopy Capsule Retention Causing Delayed Intestinal Obstruction in a Patient with a Small Bowel Neuroendocrine Tumor.

Am J Case Rep 2021 Jul 24;22:e932419. Epub 2021 Jul 24.

2nd Propaedeutic Department of Surgery, Aristotle University School of Medicine, Hippokration General Hospital, Thessaloniki, Greece.

BACKGROUND Capsule endoscopy has played a significant role in small bowel investigation, providing the opportunity of detecting neoplastic lesions to a greater degree and at an earlier stage than other diagnostic procedures. Failure to excrete the capsule with the feces within 48 h can lead to capsule retention with increased risk of further complications such as bowel obstruction and perforation. Capsule retention can remain undetected in case of incomplete follow-up and poor patient compliance. Read More

Surveillance for low-risk kidney cancer: a narrative review of contemporary worldwide practices.

Transl Androl Urol 2021 Jun;10(6):2762-2786

Urology Department, Oxford University Hospitals NHS Foundation Trust, Oxford, UK.

The management trend of low-risk kidney cancer over the last decade has been from treatment with radical nephrectomy, to use of nephron sparing procedures of partial nephrectomy and ablation, as well as the option of active surveillance (AS). This narrative review aims to summarise the available guidelines related to AS and review the published descriptions of regional practices on the management of low-risk kidney cancer worldwide. A search of PubMed, Google Scholar and Cochrane Library databases for studies published 2010 to June 2020 identified 15 studies, performed between 2000 and 2019, which investigated 13 different cohorts of low-risk kidney cancer patients on AS.

Fertility-sparing approach for endometrial cancer: the role of office hysteroscopy.

Minim Invasive Ther Allied Technol 2021 Jul 22:1-8. Epub 2021 Jul 22.

Department of Obstetrics and Gynecology, University of California Davis Medical Center, Sacramento, CA, USA.

Endometrial cancer is the most common gynecologic malignancy in developed countries, with increasing incidence among younger, nulliparous patients. These epidemiological shifts are attributed to increasing rates of obesity, in combination with delayed childbearing. This highlights a need for fertility-sparing options for individuals who wish to delay standard surgical management with hysterectomy, bilateral salpingoophorectomy, and assessment of pelvic/para-aortic lymph nodes.
