Chun-Dong Zhang教授の研究室は、消化器がん、特に胃がんと若年性大腸がんの発症メカニズムと予後予測因子の解明を主眼としています。特に腫瘍微小環境における低酸素状態の影響や、リンパ管侵犯(LVI)といった病理的因子が治療成績に与える影響を、臨床的・分子的アプローチで解明しています。また、手術法の最適化やがん細胞の増殖・壊死の制御に関与する新規遺伝子(PRR11)の機能解明にも取り組んでいます。

Despite large variations in regional and national levels, the global incidence rate, death rate, and DALY rate increased during the past three decades. These findings may provide policymakers with an accurate quantification of the burden of early-onset CRC and targeted identification of those most at risk to mitigate the burden of early-onset CRC.
The hypoxia risk score model revealed a close relationship between hypoxia and tumor immune microenvironment. The current study potentially provides new insights of how hypoxia affects the prognosis, and may provide a new therapeutic target for patients with gastric cancer.
LVI is an independent prognostic factor predicting LN metastasis and a strongly independent predictor of survival for patients with resected gastric cancer. We recommend that LVI should be taken into account as an important adjuvant prognostic factor, specially for pN0 cases with inadequate LNs retrieved. And the maximum number of LNs possible should be retrieved for optimal staging, especially for patients with higher cT stage.
In Asian patients, LADG had similar mortality and oncological safety, better surgical safety, less operative morbidity, less trauma, and faster recovery than ODG. It has a high role to play in node-negative cases due to better short-term outcomes but less nodal harvest. It is a recommended alternative treatment for experienced surgeons in high-volume centers.
Gastrectomy plus D2 lymphadenectomy plays a decisive role in the management of resectable gastric cancer in Japan. Before recent advances in chemotherapy, Japanese surgeons considered that extensive surgery involving extended lymphadenectomy with combined resection of neighboring organ(s) was required to eliminate any possible lymphatic cancer spread and improve patient survival. This approach differs radically from that in Western countries, which aim to improve survival outcomes by multidiscip
Our previous studies have demonstrated that proline-rich protein 11 (PRR11) is a novel tumor-related gene and implicates in regulating the proliferation in lung cancer. However, its precise role in cell cycle progression remains unclear. Our recent evidences show that PRR11 silencing has an effect on autophagy in non-small-cell lung cancer (NSCLC) cells. Two human NSCLC cell lines, H1299 and A549 were transiently transfected with against PRR11 siRNA. The Cell Counting Kit-8 and plate clone forma
For the treatment of EGC in Asia, LG has several advantages, including safety, less trauma, and faster recovery. Our results should be validated in western studies.
The actin cytoskeleton is extremely dynamic and supports diverse cellular functions in many physiological and pathological processes, including tumorigenesis. However, the mechanisms that regulate the actin-related protein 2/3 (ARP2/3) complex and thereby promote actin polymerization and organization in cancer cells are not well-understood. We previously implicated the proline-rich 11 (PRR11) protein in lung cancer development. In this study, using immunofluorescence staining, actin polymerizati
This study revealed differences in the burdens and temporal trends of EOGC, IOGC, and LOGC, and highlighted the importance of tailored cancer-control measures in neglected subpopulations, especially in patients with EOGC.
Preoperative nutritional and inflammatory factors have significant prognostic value in patients with CRC. A novel prognostic model incorporating preoperative inflammatory and nutritional markers provides better prognostic performance than the AJCC 8th TNM classification. A novel nomogram incorporating preoperative inflammatory and nutritional markers can individually predict OS and DFS in patients with CRC.
