Prevalence of acute oral mucosal damage secondary to the use of systemic antineoplastics: A systematic review and meta-analysis. Oral Surg Oral Med Oral Pathol Oral Radiol 2023; 135:385-395. [PMID: 36585342 DOI: 10.1016/j.oooo.2022.11.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 11/22/2022] [Accepted: 11/29/2022] [Indexed: 12/13/2022]
Abstract
OBJECTIVE The aim of this study was to determine the prevalence of acute oral mucosal toxicities in non-irradiated patients treated with systemic antineoplastics agents. The secondary objective was to find out differences in its prevalence among the different types of systemic antineoplastics. STUDY DESIGN A systematic review and meta-analysis was performed. Articles from 2010 to July 2022 were retrieved and included if patients were adults undergoing oral assessment after administration of commercially available systemic antineoplastics. Data was extracted and pooled proportions were estimated using random-effect model method (Der Simonian and Lair). RESULTS Eighty-two articles were included in the study. The overall prevalence of acute oral mucosal damage across studies was 38.2% (95% CI: 33.1%-43.3%). The prevalence was 42.9% (95% CI: 32.8%-53%) in patients treated with chemotherapy alone, 38% (95% CI: 29.1%-47%) in patients treated with a combination of chemotherapy and targeted therapies, and 32.1% (95% CI: 26.8%-37.5%) in targeted therapies alone-treated patients. No statistically significant differences were found in the prevalence of oral mucosal toxicities between the different types of systemic antineoplastic treatments. CONCLUSIONS Oral mucosal toxicity is a major side effect in non-irradiated cancer patients undergoing systemic antineoplastics.

Looking for a strategy in treating peritoneal gastric cancer carcinomatosis: an Italian multicenter Gastric Cancer Research group's analysis. World J Surg Oncol 2021; 19:334.

Abstract
BACKGROUND The present study provides a snapshot of Italian patients with peritoneal metastasis from gastric cancer treated by surgery in Italian centers belonging to the Italian Research Group on Gastric Cancer. Prognostic factors affecting survival in such cohort of patients were evaluated with the final aim to identify patients who may benefit from radical intent surgery. METHODS It is a multicentric retrospective study based on a prospectively collected database including demographics, clinical, surgical, pathological, and follow-up data of patients with gastric cancer and synchronous macroscopic peritoneal metastases. Patients were surgically treated from January 2005 to January 2017. We focused on patients with macroscopic peritoneal carcinomatosis (PC) treated with upfront surgery in order to provide homogeneous evidences. RESULTS Our results show that patients with peritoneal carcinomatosis cannot be considered all lost. Strictly selected cases (R0/R1 and P1 patients) could benefit from an aggressive surgical approach performing an extended lymphadenectomy and HIPEC treatment. CONCLUSION The main result of the study is that GC patients with limited peritoneal involvement can have a survival benefit from a surgery with "radical oncological intent", that means extended lymphadenectomy and R0 resection. The retrospective nature of this study is an important bias, and for this reason, we have started a prospective multicentric study including Italian stage IV patients that hopefully will give us more answers.

Hedgehog signaling activation required for glypican-6-mediated regulation of invasion, migration, and epithelial-mesenchymal transition of gastric cancer cells. Biosci Rep 2021; 40:225096. [PMID: 32478377 PMCID: PMC7295629 DOI: 10.1042/bsr20193181] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 05/13/2020] [Accepted: 05/13/2020] [Indexed: 02/08/2023] Open
Abstract
Gastric cancer (GC) is the fifth most common cancer worldwide and one of the most aggressive cancers in China. Glypican 6 is highly expressed in gastric adenocarcinoma and may act as a diagnostic and prognostic marker; however, the functional importance and molecular mechanism of glypican 6 in GC remains unclear. In the current study, we aimed to reveal the function and mechanism of glypican 6 in two GC cell lines: MKN-45 and SGC-7901. We found higher expression of glypican 6 in MKN-45 and SGC-7901 cells than in cells from the normal gastric mucosa epithelial cell line GES-1. Glypican 6 knockdown suppressed MKN-45 and SGC-7901 cell proliferation. A Transwell assay confirmed that glypican 6 silencing inhibited the migration and invasiveness of MKN-45 and SGC-7901 cells. Epithelial-to-mesenchymal transition (EMT) markers were determined by western blotting, and the results showed reduced Vimentin expression and elevated E-cadherin expression in glypican 6 short interfering RNA (siRNA) transfected MKN-45 and SGC-7901 cells. However, glypican 6 overexpression in GES-1 cells showed no significant promotion on GES-1 cells proliferation and migration. Further studies confirmed that glypican 6 siRNA regulated Hedgehog and Gli1 signaling and participated in the function of glypican 6 on MKN-45 and SGC-7901 cell migration and invasion. Our findings suggest that decreased glypican 6 expression inhibits the migration and invasion ability of GC cells.

Abstract
Gastric cancer is a common digestive tract tumor and the second most prevalent cancer. The prognosis of advanced gastric cancer is poor. Conversion therapy can reduce tumor burden, downgrade tumor, and increase the possibility of complete resection, thus prolonging the survival time of patients with gastric cancer. In conversion therapy, chemotherapy and targeted therapy are the main methods of medical treatment, which can control tumor growth and recurrence. As an antiangiogenic targeted drug, apatinib is widely used in the third-line treatment of advanced gastric cancer. Recent studies have shown that it may be of great help in rapid reduction of tumor stage and improvement of prognosis in conversion therapy. This study reported three cases of gastric cancer complicated with multiple abdominal and retroperitoneal lymph node metastases. After receiving apatinib combined with SOX regimen for four cycles, computed tomography showed that the focus and lymph node metastasis were reduced after treatment, and primary tumors were resected. Postoperative pathology result showed that the patients got R0 resection. After radical surgery, the maintenance therapy including apatinib was given. The progression-free survival time was more than 10 months. Apatinib combined with SOX regimen as a conversion therapy for advanced gastric adenocarcinoma increases the possibility of successful surgical resection, which might prolong the survival time of patients.

[PMID: 29754469 PMCID: PMC5974616 DOI: 10.14348/molcells.2018.2078] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2017] [Revised: 02/28/2018] [Accepted: 03/15/2018] [Indexed: 12/11/2022] Open
Abstract
Studies have revealed that miR-103a-3p contributes to tumor growth in several human cancers, and high miR-103a-3p expression is associated with poor prognosis in advanced gastric cancer (GC) patients. Moreover, bioinformatics analysis has shown that miR-103a-3p is upregulated in The Cancer Genome Atlas (TCGA) stomach cancer cohort. These results suggest that miR-103a-3p may function as an oncogene in GC. The present study aimed to investigate the role of miR-103a-3p in human GC. miR-103a-3p expression levels were increased in 33 clinical GC specimens compared with adjacent nontumor stomach tissues. Gain- and loss-of-function studies were performed to identify the correlation between miR-103a-3p and tumorigenesis in human GC. Inhibiting miR-103a-3p suppressed GC cell proliferation and blocked the S-G2/M transition in MKN-45/SGC-7901 cells, whereas miR-103a-3p overexpression improved GC cell proliferation and promoted the S-G2/M transition in vitro. Bioinformatics and dual-luciferase reporter assays confirmed that ATF7 is a direct target of miR-103a-3p. Analysis of the TCGA stomach cancer cohort further revealed that miR-103a-3p expression was inversely correlated with ATF7 expression. Notably, silencing ATF7 showed similar cellular and molecular effects as miR-103a-3p overexpression, namely, increased GC cell proliferation, improved CDK2 expression and decreased P27 expression. ATF7 overexpression eliminated the effects of miR-103a-3p expression. These findings indicate that miR-103a-3p promotes the proliferation of GC cell by targeting and suppressing ATF7 in vitro.

Abstract
BACKGROUND Advanced unresectable gastric cancer has a dismal prognosis. The aim of this study was to evaluate the short- and long-term outcomes of patients who underwent induction chemotherapy ± gastrectomy for advanced gastric cancer. MATERIAL AND METHODS All patients referred to our center with a clinical diagnosis of unresectable locally advanced or stage IV gastric adenocarcinoma between April 2005 and August 2016 were included in the study. Cox regression was performed to find independent prognostic factor among the considered variable. RESULTS The cohort included 73 patients: 16 had best supportive care, 35 chemotherapy alone and 22 chemotherapy plus radical surgery. Thirty-three patients underwent surgery after chemotherapy. Twenty-two patients had R0 surgery, while the remaining 11 had only an exploratory procedure. Nine patients (40.9%) underwent gastrectomy plus hyperthermic intraperitoneal chemotherapy. Three patients out of 22 developed postoperative complications with a Clavien-Dindo grade above 2. Median survival was 50 months for patients who had chemotherapy plus surgery while it was 14 and 3 for those who had chemotherapy alone and best supportive care, respectively (p < 0.0001). Cox regression analysis performed on the whole cohort identified only radical conversion surgery as an independent factor positively associated with survival (HR 0.12, 95% CI 0.05-0.29, p < 0.0001). CONCLUSION Conversion gastrectomy, when R0 could be achieved, is associated with long survivals and it is the most important prognostic factor in patients with advanced gastric cancer. Further studies are needed to define the ideal patient who can really benefit from this treatment.

Nuclear heat shock protein 110 expression is associated with poor prognosis and hyperthermo-chemotherapy resistance in gastric cancer patients with peritoneal metastasis. World J Gastroenterol 2017; 23:7541-7550. [PMID: 29204054 PMCID: PMC5698247 DOI: 10.3748/wjg.v23.i42.7541] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2017] [Revised: 09/08/2017] [Accepted: 09/19/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate the significance of heat shock protein 110 (HSP110) in gastric cancer (GC) patients with peritoneal metastasis undergoing hyperthermo-chemotherapy.
METHODS Primary GC patients (n = 14) with peritoneal metastasis or positive peritoneal lavage cytology who underwent distal or total gastrectomy between April 2000 and December 2011 were enrolled in this study. The patients underwent postoperative intraperitoneal hyperthermo-chemotherapy using a Thermotron RF-8 heating device two weeks after surgery. We analyzed nuclear HSP110 expression in surgically resected tumors using immunohistochemistry. Additionally, the effect of HSP110 suppression on hyptherthermo-chemosensitivity was assessed in vitro in the MKN45 GC cell line using the HSP inhibitor KNK437.
RESULTS HSP110 immnohistochemical staining in 14 GC patients showed that five (35.7%) samples belonged to the low expression group, and nine (64.3%) samples belonged to the high expression group. Progression-free survival was significantly shorter in the HSP110 high-expression group than in the low-expression group (P = 0.0313). However, no significant relationships were identified between HSP110 expression and the clinicopathological characteristics of patients. Furthermore, high HSP110 expression was not an independent prognostic factor in GC patients with peritoneal metastasis (P = 0.0625). HSP110 expression in MKN45 cells was suppressed by KNK437 at the hyperthermic temperature of 43 °C in vitro. Comparison of MKN45 cell proliferation in the presence and absence of KNK437 at 43 °C, revealed that proliferation was significantly decreased when HSP110 was inhibited by KNK437. Additionally, HSP110 suppression via HSP inhibitor treatment increased cellular sensitivity to hyperthermo-chemotherapy in vitro.
CONCLUSION The expression of nuclear HSP110 in GC patients might be a new marker of chemosensitivity and a therapeutic target for patients who are tolerant to existing hyperthermo-chemotherapies.

Abstract
Studies have shown that miR-4317 is dysregulated in tumor, but the biologic role of miR-4317 in tumor development and progression remains unknown. The present study aimed to investigate the role of miR-4317 in human gastric cancer. Quantitative real-time PCR was used to quantify miR-4317 expression levels in clinical gastric cancer specimens and cell lines. MTT, colony formation and cell cycle assays were performed to identify the contributions of miR-4317 to cell proliferation in gastric cancer cell lines. The results showed that miR-4317 was significantly decreased in 17 clinical gastric cancer specimens compared with adjacent non-tumor stomach tissues. Forced expression of miR-4317 suppressed gastric cancer cell proliferation and blocked S-G2/M transition. Bioinformatics and dual-luciferase reporter assays confirmed that ZNF322 is a direct target of miR-4317. Silencing ZNF322 recapitulated the cellular and molecular effects seen upon miR-4317 overexpression. These findings indicate that miR-4317 represses the proliferation of gastric cancer cell, at least in part, by targeting and suppressing ZNF322 and that it may serve as a therapeutic target for gastric cancer treatment.

Abstract
In gastric cancer, primary systemic chemotherapy is the standard approach for the management of patients with initially unresectable metastasis, and it occasionally leads to a reduction in the size of the lesion, which facilitates surgical resection. The aim of this study was to examine the prognosis of patients who were able to undergo complete resection following chemotherapy. A total of 10 patients who underwent radical surgery for stage IV primary gastric cancer after chemotherapy between 2009 and 2015 at the Department of Surgery of Hokkaido Social Work Association Obihiro Hospital (Obihiro, Japan) were retrospectively investigated. Three regimens were used (S-1, n=1; S-1 + cisplatin, n=8; and S-1 + docetaxel, n=1). The mean time from chemotherapy to surgery was 210 days. One total gastrectomy + splenectomy + colectomy, one total gastrectomy + splenectomy, four total gastrectomies and three distal gastrectomies were performed. There were two cases of pancreatic fistula formation postoperatively. All the patients survived for >1 year. Of the 10 patients, 5 survived without recurrence. The median survival time was 871.1 days after diagnosis. Therefore, curative resection after chemotherapy is associated with a better prognosis in stage IV gastric cancer patients.

Abstract
S-1 is a novel oral fluoropyrimidine derivative, widely used for treating gastric, pancreatic, lung, head, neck and breast carcinomas. It is designed to enhance the clinical utility of an oral fluoropyrimidine and is associated with low gastrointestinal toxicity. S-1 consists of three pharmacological agents (at a molar ratio of 1:0.4:1)-Tegafur (FT), a prodrug of 5-Fluorouracil (5-FU), 5-Chloro-2-4-Dihydroxypyridine (CDHP), which inhibits the activity of Dihydropyrimidine Dehydrogenase (DPD) and Oxonic Acid (Oxo), which reduces Gastrointestinal (GI) toxicity of 5-FU. The present article reviews the current development of clinical study of S-1.

Is conversion therapy possible in stage IV gastric cancer: the proposal of new biological categories of classification. Gastric Cancer 2016; 19:329-338. [PMID: 26643880 PMCID: PMC4824831 DOI: 10.1007/s10120-015-0575-z] [Citation(s) in RCA: 205] [Impact Index Per Article: 25.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2015] [Accepted: 11/06/2015] [Indexed: 02/07/2023]
Abstract
Conversion therapy for gastric cancer (GC) has been the subject of much recent attention. It is defined as a surgical treatment aiming at an R0 resection after chemotherapy for tumors that were originally unresectable or marginally resectable for technical and/or oncological reasons. However, the indications for resection remain to be clarified. In the present review, we focus on the biology and heterogeneous characteristics of stage IV GC and propose new categories of classification. Stage IV GC patients can be divided based on the absence (categories 1 and 2) or presence (categories 3 and 4) of macroscopically detectable peritoneal dissemination, which has a different biological outcome compared to hematological metastasis. Category 1 is defined oncologically as stage IV but the metastasis is technically resectable. Category 2 includes a marginally resectable metastasis or patients for whom the operation would not necessarily be the best choice. Category 3 includes a potentially unresectable metastasis of peritoneal dissemination that is only macroscopically detectable. Category 4 includes noncurable metastasis with peritoneal and other organ metastasis. The indications for conversion therapy might include the patients from category 2, some patients from category 3 and a very small number of patients from category 4. The longer survival can be expected for patients corresponding to categories 1, 2 and, to a lesser extent, 3, while the treatment of other patients focuses on "care." The provision of conversion therapy for stage IV GC patients might be one of the main roles of surgical oncologists in the near future.

Abstract
BACKGROUND Both docetexal plus S-1 (DS) and oxaliplatin plus S-1 (SOX) are active regimens currently used in patients with advanced gastric cancer. In this retrospective study, efficacy and safety of these 2 combination regimens were evaluated. PATIENTS AND METHODS Patients received docetaxel infusion 75 mg/m(2) in the DS group or oxaliplatin infusion 130 mg/m(2) in the SOX group at day 1 of each 3-week cycle. S-1 40 mg/m(2) was administered orally twice daily on days 1-14 in the 3-week cycle in both groups. Progression-free survival (PFS), overall survival (OS) and safety perimeters were evaluated. RESULTS 84 patients were retrospectively evaluated in the study: 36 patients in the DS group and 48 patients in the SOX group. The median PFS was 6.55 months in the DS group and 5.73months in the SOX group. The median OS was 13.97 in the DS group and 13.13 months in the SOX group. The overall response rates were 41.7% and 43.8% and the disease control rates were 77.8% and 87.5% for DS and SOX, respectively. The most frequent grade 3 and 4 toxicities were thrombocytopenia for DS (19.4%) and anemia for SOX (12.5%). CONCLUSION Both regimens were active and well tolerated in advanced gastric cancer patients. © 2014 S. Karger GmbH, Freiburg.

Abstract
Gastric cancer is the fourth most common malignancy worldwide. More than 50% of gastric cancer patients have unresectable disease at diagnosis, and there is a high rate of local or distant recurrence, even in patients with an operable tumor. Chemotherapy is regarded as a significant and basic treatment that can provide a longer symptom-free period and improve quality of life. S-1 is a novel oral derivative of 5-FU. Compared with 5-FU, S-1 is more tolerable and effective, and will be more convenient to use for patients with advanced gastric cancer. Recent phase II randomized trials of S-1 based chemotherapy have achieved encouraging results with regard to objective response rate and overall survival. This paper aims to review the efficacy of S-1 in treating advanced gastric cancer, molecular markers that can predict efficacy, and the prospect for therapy with S-1 in combination with new chemotherapeutic drugs or molecularly targeted drugs.

Abstract
OBJECTIVE To evaluate the efficacy of HangAm-Plus (HAP) on stage IV metastatic gastric cancer by analyzing the treated patients' overall survival outcome. METHODS Following the study eligibility, overall survival and one year survival rate of 44 stage IV metastatic gastric cancer patients who visited East-West Cancer Center (EWCC) were analyzed. The study consisted of two arms: HAP treatment only (n=18) and combined treatment of concurrent conventional chemotherapy and HAP (n=26). Patient characteristics by gender, age, surgical intervention, Eastern Cooperative Oncology Group (ECOG) score, treatment duration (< 4 weeks or [Symbol: see text]4 weeks), and lines of the chemotherapy received were assessed. Treatment related side effects were also assessed. RESULTS The median survival of combined group was longer (10.0 months) than that of HAP group (5.1 months). One-year survival rate of combined treatment group and HAP group was 38.5%±9.5% and 33.3%±11.1%, respectively (P>0.05). One-year survival rate of those received more and less than 4-week treatment was 57.1%±18.7% and 8.3%±8.0%, respectively (P=0.001). CONCLUSIONS The study supports the safety and potential efficacy of HAP treatment in prevention of chemo-related side effects for stage IV metastatic gastric cancer treated with conventional chemotherapy. Further studies are needed to investigate and confirm the results before applying the treatment in clinical settings.

Abstract
BACKGROUND Gastric cancer is one of the leading causes of cancer death. With greater understanding of the molecular basis of carcinogenesis, targeted agents have led to a modest improvement in the outcome of advanced gastric cancer (AGC) patients. METHODS AND RESULTS We conducted an overview of the published evidence regarding the use of targeted therapy in AGC patients. Thus far, the human epidermal growth factor receptor (HER) pathway, angiogenic pathway, and phosphatidylinositol-3-kinase (PI3K)-Akt-mammalian target of rapamycin pathway have emerged as potential avenues for targeted therapy in AGC patients. The promising efficacy results of the Trastuzumab for Gastric Cancer trial led to the approved use of trastuzumab-based therapy as first-line treatment for patients with HER-2+ AGC. On the other hand, the Avastin® in Gastric Cancer trial evaluating bevacizumab in combination with chemotherapy did not meet its primary endpoint of a longer overall survival duration despite a significantly higher response rate and longer progression-free survival time in patients in the bevacizumab arm. Phase III data are awaited for other targeted agents, including cetuximab, panitumumab, lapatinib, and everolimus. CONCLUSION Recent progress in targeted therapy development for AGC has been modest. Further improvement in the outcome of AGC patients will depend on the identification of biomarkers in different patient populations to facilitate the understanding of gastric carcinogenesis, combining different targeted agents with chemotherapy, and unraveling new molecular targets for therapeutic intervention.

Abstract
In the new era of technical development in surgery, operative devices, molecular targeting and chemotherapeutic agents, surgical oncologists have two main roles in the treatment of gastric cancer. One is to provide patients with minimally invasive surgery, including laparoscopy- or robot-assisted surgery in early gastric cancer patients, and the new concept of surgical intervention toward advanced and metastatic disease. Since recently, laparoscopy-assisted distal gastrectomy has become prevalent in Japan as a surgery which is minimally invasive for the patients and provides them with a good quality of life afterwards. However, the provision of advanced surgical techniques, including lymph node dissection and reconstruction, is more important for patient survival. The second role of surgical oncologists is to evaluate the significant values of the aggressive treatment which we term 'adjuvant surgery' for stage IV gastric cancer patients who have successfully responded to initial chemotherapy for curative intent. Stage IV gastric cancer patients are now being informed about the possibility of longer survival with the new chemotherapeutic and surgical strategic approach.

Abstract
This study concerns the encapsulation and controlled release of both hydrophobic and hydrophilic medications with one polymer, which are delivered together as a combined therapy to treat diseased tissue. To test our hypothesis that the novel PEG-graft-PLA (PEG, polyethylene glycol; PLA, polylactic acid) can deliver both the hydrophobic and hydrophilic medications on account of its amphiphility, charge, and graft structure, PEG-graft-PLA (molecular weight of PEG = 1900) with very low critical micelle concentration was synthesized. One hydrophilic (insulin) and one hydrophobic (naproxen) model medication were loaded in separately during its self-assembly in aqueous solution. The resulting nanoparticles (NPs) were narrowly distributed and spherical, with average particle size around 200 nm, zeta potential >-10 mV, and encapsulation efficiency >50%. The NPs realized controlled release of insulin and naproxen for over 24 and 160 hours, respectively. Specifically, the bioactivity of the insulin released from the NPs was maintained. Owing to encapsulation, both for hydrophobic and hydrophilic medicines, and NPs obtained with similar size and zeta potential, as well as maintenance of bioactivity of loaded protein, we expect the applications of PEG-graft-PLA NPs in combination therapy.
