Oncological outcomes of conversion therapy in gastric cancer patients with peritoneal metastasis: a large-scale retrospective cohort study. Gastric Cancer 2024; 27:387-399. [PMID: 38143257 PMCID: PMC10896904 DOI: 10.1007/s10120-023-01452-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 11/19/2023] [Indexed: 12/26/2023]
Abstract
BACKGROUND Data on the long-term oncological outcomes of patients who undergo conversion surgery (CS) in gastric cancer (GC) patients with peritoneal metastasis (PM) are limited. METHODS GC patients with PM who received intraperitoneal (ip) and systemic chemotherapy between April 2015 and January 2021 were enrolled. Multivariate analysis was performed to identify risk factors associated with survival. Clinicopathological and survival outcomes were compared between those with CS and those without CS (NCS). The paclitaxel (PTX) plus tegafur-gimeracil-oteracil potassium capsules (S-1) (PS) + ip PTX and oxaliplatin plus S-1 (SOX) + ip PTX groups were matched in a 1:1 ratio using propensity score matching. Oncological and survival data were collected and analyzed. RESULTS A total of 540 patients who received ip chemotherapy via subcutaneous port and systemic chemotherapy were analyzed and 268 patients were enrolled, including 113 who underwent CS and 155 who did not. Overall survival (OS) were 27.0 months and 11.8 months in the CS and NCS groups (P < 0.0001), respectively. R0 resection was an independent prognostic factor for patients who underwent CS. The OS of patients with or without ovariectomy was 21.3 or 12.0 months (P < 0.0001). No difference of clinicopathological and survival outcomes was found between the PS + ip PTX and SOX + ip PTX groups. CONCLUSION Conversion therapy is safe and adverse events were manageable. CS improves the survival of GC patients with PM after ip and systemic chemotherapy. R0 is an important prognostic factor. Furthermore, outcomes are comparable between the PS + ip PTX and SOX + ip PTX groups.

Liquid biopsy: circulating tumor DNA monitors neoadjuvant chemotherapy response and prognosis in stage II/III gastric cancer. Mol Oncol 2023; 17:1930-1942. [PMID: 37356061 PMCID: PMC10483607 DOI: 10.1002/1878-0261.13481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 03/09/2023] [Accepted: 06/23/2023] [Indexed: 06/27/2023] Open
Abstract
A good response to neoadjuvant chemotherapy (NACT) is strongly associated with a higher curative resection rate and favorable outcomes for patients with gastric cancer (GC). We examined the utility of serial circulating tumor DNA (ctDNA) testing for monitoring NACT response and prognosis in stage II-III GC. Seventy-nine patients were enrolled to receive two cycles of NACT following gastrectomy with D2-lymphadenectomy. Plasma at baseline, post-NACT, and after surgery, and tissue at pretreatment and surgery were collected. We used a 425-gene panel to detect genomic alterations (GAs). Results show that the mean cell-free DNA concentration of patients with clinical stage III was significantly higher than patients with stage II (15.43 ng·mL-1 vs 14.40 ng·mL-1 ). After receiving NACT and surgery, the overall detection rate of ctDNA gradually reduced (59.5%, 50.8%, and 47.4% for baseline, post-NACT, and postsurgery). The maximum variant allele frequency (max-VAF) and the number of GAs decreased from 0.50% to 0.08% and from 2.9 to 1.7 after NACT. For patients with a partial response after NACT, the max-VAF and the number of GAs declined significantly, but they increased for patients with progressive disease. Patients with detectable ctDNA at baseline, after NACT, or after surgery have a worse overall survival (OS) than patients with undetectable ctDNA. The estimated 3-year OS was 73% for the post-NACT ctDNA-negative patients and 34% for ctDNA-positive. Patients with perpetual negative ctDNA before and after NACT have the best prognosis. In conclusion, ctDNA was proposed as a potential biomarker to predict prognosis and monitor the NACT response for stage II-III GC patients.

World J Gastrointest Oncol 2023; 15:286-302. [PMID: 36908323 PMCID: PMC9994047 DOI: 10.4251/wjgo.v15.i2.286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 11/23/2022] [Accepted: 01/05/2023] [Indexed: 02/14/2023] Open
Abstract
BACKGROUND Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a newly discovered oncogene. It is an active cell proliferation regulatory factor that inhibits tumor apoptosis in gastric cancer (GC) cells. CIP2A is functionally related to chemoresistance in various types of tumors according to recent studies. The underlying mechanism, however, is unknown. Further, the primary treatment regimen for GC is oxaliplatin-based chemotherapy. Nonetheless, it often fails due to chemoresistance of GC cells to oxaliplatin.
AIM The goal of this study was to examine CIP2A expression and its association with oxaliplatin resistance in human GC cells.
METHODS Immunohistochemistry was used to examine CIP2A expression in GC tissues and adjacent normal tissues. CIP2A expression in GC cell lines was reduced using small interfering RNA. After confirming the silencing efficiency, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium and flow cytometry assays were used to evaluate cell proliferation and apoptosis caused by oxaliplatin treatment. Further, the key genes and protein changes were verified using real-time quantitative reverse transcription PCR and Western blotting, respectively, before and after intervention. For bioinformatics analysis, we used the R software and Bioconductor project. For statistical analysis, we used GraphPad Prism 6.0 and the Statistical Package for the Social Sciences software version 20.0 (IBM, Armonk, United States).
RESULTS A high level of CIP2A expression was associated with tumor size, T stage, lymph node metastasis, Tumor Node Metastasis stage, and a poor prognosis. Further, CIP2A expression was higher in GC cells than in normal human gastric epithelial cells. Using small interfering RNA against CIP2A, we discovered that CIP2A knockdown inhibited cell proliferation and significantly increased GC cell sensitivity to oxaliplatin. Moreover, CIP2A knockdown enhanced oxaliplatin-induced apoptosis in GC cells. Hence, high CIP2A levels in GC may be a factor in chemoresistance to oxaliplatin. In human GC cells, CIP2A regulated protein kinase B phosphorylation, and chemical inhibition of the protein kinase B signaling pathway was significantly associated with increased sensitivity to oxaliplatin. Therefore, the protein kinase B signaling pathway was correlated with CIP2A-enhanced chemoresistance of human GC cells to oxaliplatin.
CONCLUSION CIP2A expression could be a novel therapeutic strategy for chemoresistance in GC.

Biweekly oxaliplatin plus S1 for Chinese elderly patients with advanced gastric or gastroesophageal junction cancer as the first-line therapy: a single-arm, phase 2 study. BMC Cancer 2022; 22:253. [PMID: 35264150 PMCID: PMC8908595 DOI: 10.1186/s12885-022-09332-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Accepted: 02/23/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND SOX (oxaliplatin and S1, every 3 weeks) is one of the most common first-line chemotherapy for advanced or metastatic G/GEJ (gastric or gastroesophageal junction) cancer in Asia, but it has noticeable hematological and neurological toxicity. In China, the majority of gastric cancer patients are middle-aged and elderly with poor tolerance to 3-weekly chemotherapy. Therefore, we aimed to assess efficacy and safety of biweekly SOX for Chinese advanced G/GEJ cancer patients aged ≥ 60 years as the first-line treatment in a single arm phase 2 study. METHODS Oxaliplatin was administered intravenously on day 1 at 85 mg/m2. S-1 was given at 80, 100 or 120 mg/day, depending on the body surface area (< 1.25 m2, 1.25 to < 1.5 m2, or ≥ 1.5 m2), twice daily, on day 1-10, every 2 weeks. The primary endpoint was objective response rate (ORR), and the secondary endpoints included progression free survival (PFS), overall survival (OS), disease control rate (DCR), duration of response (DOR) and safety. RESULTS Between May 2016 and Sep 2018, 42 patients were enrolled. The median follow-up was 43.6 months. The ORR and DCR were 52.4% and 85.7%, respectively. The median PFS was 4.6 months (95%CI 2.486-6.714), and the median OS was 11.1 months (95%CI 8.001-14.199). The most common treatment-related adverse events (TRAEs) of any grade included thrombocytopenia (59.5%), neutropenia (57.1%), appetite loss (57.1%) and nausea (54.8%). Only two patients suffered from grade 3 TRAEs (4.8%), including neutropenia (1 patient, [2.4%]) and diarrhea (1 patient, [2.4%]). No ≥ grade 4 TRAEs occurred. CONCLUSIONS Biweekly SOX seemed to have favorable tolerance without compromising the efficacy as the first-line therapy in Chinese elderly patients aged ≥ 60 years with advanced G/GEJ cancer. TRIAL REGISTRATION ClinicalTrials.gov ID: NCT04694404 (5/1/2021). This study was approved by the Ethical Committee of National Cancer Center/ National Clinical Research Center for Cancer/ Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, (17-048/1303).

Abstract
The most common treatment for advanced gastric cancer (AGC) is systemic chemotherapy. The standard treatment for advanced gastric cancer differs worldwide. In Japan, two phase III clinical trials demonstrated the non-inferiority of S-1 compared with 5-fluorouracil (5-FU) and superiority of cisplatin plus S-1 (CS), compared with S-1, with respect to overall survival (SPIRITS trial). Oxaliplatin (L-OHP) has a favorable toxicity profile compared with cisplatin; hence, a phase III clinical trial (G-SOX trial) demonstrated the progression-free survival (PFS) and overall survival in CS was 5.4 and 13.1 months and those in SOX was 5.5 and 14.1 months, respectively. Serious adverse events were more frequently seen in CS than in SOX. So, SOX is as effective as CS for advanced gastric cancer with favorable safety profile. After the publication of this G-SOX trial, the combination of oral or intravenous 5-FU and various doses of L-OHP have been reported. And FOLFOX6 regimen (FOLFOX: a combination of 1-LV and FU with L-OHP) was approved for the treatment of AGC in Japan in 2017. FOLFOX was promising for patients with severe peritoneal metastasis from AGC, because the FOLFOX regimen does not require hydration and does not include oral agents. This review summarizes the efficacy and safety of doublet combinations of platinum and fluoropyrimidines using L-OHP for advanced gastric cancer.

Abstract
In an era when cancer glycobiology research is exponentially growing, we are witnessing a progressive translation of the major scientific findings to the clinical practice with the overarching aim of improving cancer patients' management. Many mechanistic cell biology studies have demonstrated that heparan sulfate (HS) glycosaminoglycans are key molecules responsible for several molecular and biochemical processes, impacting extracellular matrix properties and cellular functions. HS can interact with a myriad of different ligands, and therefore, hold a pleiotropic role in regulating the activity of important cellular receptors and downstream signalling pathways. The aberrant expression of HS glycan chains in tumours determines main malignant features, such as cancer cell proliferation, angiogenesis, invasion and metastasis. In this review, we devote particular attention to HS biological activities, its expression profile and modulation in cancer. Moreover, we highlight HS clinical potential to improve both diagnosis and prognosis of cancer, either as HS-based biomarkers or as therapeutic targets.

Abstract
BACKGROUND Curing locally advanced gastric cancer through surgery alone is difficult. Adjuvant and neoadjuvant chemotherapy bring potential benefits to more patients with gastric cancer based on several clinical trials. According to phase II studies and guidelines, SOX regimen as neoadjuvant chemotherapy is efficient. However, the optimal duration of neoadjuvant chemotherapy has not been established. In this study, we will evaluate the efficacy and safety of different cycles of SOX as neoadjuvant chemotherapy for patients with locally advanced gastric cancer. METHODS RESONANCE-II trial is a prospective, multicenter, randomized, controlled phase III study which will enroll 524 patients in total. Eligible patients will be registered, pre-enrolled and receive three cycles of SOX, after which tumor response evaluations will be carried out. Those who show stable disease or progressive disease will be excluded. Patients showing complete response or partial response will be enrolled and assigned into either group A for another three cycles of SOX (six cycles in total) followed by D2 surgery; or group B for D2 surgery (three cycles in total). The primary endpoint is the rate of pathological complete response and the secondary endpoints are R0 resection rate, three-year disease-free survival, five-year overall survival, and safety. DISCUSSION This study is the first phase III randomized trial to compare the cycles of neoadjuvant chemotherapy using SOX for resectable locally advanced cancer. Based on a total of six to eight cycles of perioperative chemotherapy usually applied in locally advanced gastric cancer, patients in group A can be considered to have completed all perioperative chemotherapy, the results of which may suggest the feasibility of using chemotherapy only before surgery in gastric cancer. TRIAL REGISTRATION Registered prospectively in the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) with registration number ChiCTR1900023293 on May 21st, 2019.

Multicenter phase III trial of S-1 and cisplatin versus S-1 and oxaliplatin combination chemotherapy for first-line treatment of advanced gastric cancer (SOPP trial). Gastric Cancer 2021; 24:156-167. [PMID: 32596783 DOI: 10.1007/s10120-020-01101-4] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Accepted: 06/13/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND In East Asia, S-1 plus cisplatin (SP) is one of the standard first-line chemotherapy regimens for metastatic or recurrent gastric cancer (MRGC). Oxaliplatin is generally less toxic and more convenient to administer than cisplatin. PATIENTS AND METHODS This was a multicenter, phase III study assessing whether S-1/oxaliplatin (SOX) was non-inferior/superior to SP in terms of progression-free survival (PFS). Patients with MRGC were randomized 1:1 to receive either SOX (S-1 80 mg/m2/day on days 1-14; oxaliplatin 130 mg/m2 on day 1; every 3 weeks) or SP (S-1 80 mg/m2/day on days 1-14; cisplatin 60 mg/m2 on day 1; every 3 weeks [SP3]). RESULTS Between October 2012 and October 2014, 338 patients were randomized. The median age was 56 years, and 51% of patients had measurable lesions. SOX was significantly non-inferior but not superior to SP3 in terms of PFS [median 5.6 versus 5.7 months; hazard ratio (HR) 0.85; 95% confidence interval (CI) 0.67-1.07]. In patients with measurable disease, objective response rates were similar between SOX and SP3 (58% versus 60%). Overall, the survival in both groups did not differ (median 12.9 versus 11.4 months; HR 0.86; 95% CI 0.66-1.11). Treatment was well tolerated in both arms. Anemia, leucopenia, neutropenia, febrile neutropenia, and oral mucositis were more common with SP3. In contrast, thrombocytopenia, nausea, vomiting, and peripheral neuropathy were more common with SOX. CONCLUSIONS SOX was non-inferior to SP3. The two regimens were well tolerated with different toxicity profiles. The SOX regimen can be recommended as a first-line treatment for MRGC. TRIAL REGISTRATION ClinicalTrials.gov: NCT01671449.

Intraperitoneal Administration of Paclitaxel Combined with S-1 Plus Oxaliplatin as Induction Therapy for Patients with Advanced Gastric Cancer with Peritoneal Metastases. Ann Surg Oncol 2020; 28:3863-3870. [PMID: 33270170 PMCID: PMC8184712 DOI: 10.1245/s10434-020-09388-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Accepted: 11/04/2020] [Indexed: 12/27/2022]
Abstract
Background Intraperitoneal (IP) administration of paclitaxel (PTX) has a great pharmacokinetic advantage to control peritoneal lesions and can be combined with various systemic chemotherapies. In this study, we evaluate the efficacy and tolerability of a combination of IP-PTX and systemic S-1/oxaliplatin (SOX) for induction chemotherapy for patients with peritoneal metastases (PM) from gastric cancer (GC). Patients and Methods Patients with GC who were diagnosed as macroscopic PM (P1) or positive peritoneal cytology (CY1) by staging laparoscopy between 2016 and 2019 were enrolled. PTX was IP administered at 40 mg/m2 on days 1 and 8. Oxaliplatin was IV administered at 100 mg/m2 on day 1, and S-1 was administered at 80 mg/m2/day for 14 consecutive days, repeated every 21 days. Survival time and toxicities were retrospectively explored. Results Forty-four patients received SOX + IP-PTX with a median (range) of 16 (1–48) courses, although oxaliplatin was suspended due to the hematotoxicity or intolerable peripheral neuropathy in many patients. The 1-year overall survival (OS) rate was 79.5% (95% CI 64.4–88.8%) with median survival time of 25.8 months. Gastrectomy was performed in 20 (45%) patients who showed macroscopic shrinkage of PM with a 1-year OS rate of 100% (95% CI 69.5–100%). Grade 2 and 3 histological responses was achieved in four (20%) and one (5%) patients. Grade 3/4 toxicities included neutropenia (11%), leukopenia (39%), and anemia (14%). There were no treatment-related deaths. Conclusions Combination chemotherapy using SOX + IP-PTX regimen is highly effective and recommended as induction chemotherapy for patients with PM from GC.

Yuan C, Xie Y, Sheng X, Xie X, Liu J, Zeng S, Wang X. Role of HOXB7 in promoting gastric cancer progression and oxaliplatin (L-OHP) resistance. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2020; 13:1381-1389. [PMID: 32661473 PMCID: PMC7344019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Accepted: 05/20/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND AND AIM Our study aimed to investigate the ways by which HOXB7 affects gastric cancer progression and oxaliplatin (L-OHP) resistance. METHODS First, the expression of HOXB7 in paired cancer and paracancerous tissues of L-OHP-sensitive and L-OHP-resistant gastric cancer patients was qualitatively and quantitatively analyzed by immunohistochemistry. Then, the expression of HOXB7 in these tissues was further quantitatively analyzed at protein and transcriptional levels. The expression of HOXB7 in the SGC-7901 L-OHP-resistant gastric cancer cell line was further verified by immunofluorescence, western blot, and RT-qPCR. In addition, by transfecting the SGC-7901 cell line, control (sh-con) and HOXB-7-silenced (sh-HOXB7) gastric cancer cell lines were created. Subsequently, the migratory and invasive abilities of these cells were determined by the transwell assay. The proliferation rate of both control and HOXB-7-silenced cells induced by varying concentrations of L-OHP was detected by the CCK-8 assay, while the degree of apoptosis in the same cells induced by 60 µM L-OHP was detected by flow cytometry. RESULTS AND CONCLUSION Results suggested that HOXB7 was overexpressed in both the tissues of L-OHP-resistant gastric cancer patients and the SGC-7901 gastric cancer cell line. Moreover, HOXB7 promoted the migratory and invasive abilities of gastric cancer cells. By silencing HOXB7 protein expression, the proliferation rate of L-OHP-resistant gastric cancer cells decreased considerably, while their degree of apoptosis increased significantly. These results showed that HOXB7 promoted gastric cancer progression and L-OHP resistance.

Abstract
RATIONALE Apatinib has been proven to significantly prolong the survival of the patients with advanced chemotherapy-refractory gastric cancer. To date, studies on apatinib plus S-1 as first-line palliative therapy for metastatic gastroesophageal junction (GEJ) cancer are rare. PATIENT CONCERNS A 61-year-old female patient was admitted with dysphagia, significant loss of body weight, and poor performance status. DIAGNOSES Endoscopic biopsy revealed the diagnosis of poorly-differentiated GEJ adenocarcinoma, and the patient was clinically staged as T3NxM1G3 (IVB). INTERVENTIONS She had received 4 cycles of palliative therapy using oral apatinib (425 mg daily) plus S-1 (40 mg twice daily for 4 weeks, with a 2-week drug-free interval), followed by maintenance low-dose apatinib (250 mg daily) plus S-1 at the same dosage thereafter. OUTCOMES Her progression-free survival was nearly 5 months, and the overall survival was >11 months up to now. The adverse events were tolerable. LESSONS Apatinib plus S-1 might be an alternative option for late-stage GEJ cancer. However, high-quality trials are warranted before the recommendation of this therapeutic regimen.
