Abstract
BACKGROUND Capecitabine plus oxaliplatin (CapeOX) is a standard treatment option for advanced gastric cancer (AGC). We conducted a prospective multicenter phase II study to evaluate the efficacy and safety of CapeOX as a first-line therapy for AGC in older patients. METHODS Chemotherapy-naive patients aged ≥ 70 years with AGC were eligible. Initial treatment comprised capecitabine (2000 mg/m2 on days 1-14) and oxaliplatin (130 mg/m2 on day 1) every 3 weeks. After the initial feasibility assessment, the dose was reduced considering toxicity (capecitabine, 1500 mg/m2 on days 1-14; and oxaliplatin, 100 mg/m2 on day 1 every 3 weeks). The primary endpoint was overall survival (OS). RESULTS In total, 108 patients were enrolled, of whom 104 were evaluated. Thirty-nine patients received the original-dose treatment, whereas 65 received the reduced-dose treatment. The median OS, progression-free survival (PFS), and time to treatment failure (TTF) were 12.9 (95% CI 11.6-14.8), 5.7 (95% CI 5.0-7.0), and 4.3 (95% CI 3.9-5.7) months, respectively, for all patients; 13.4 (95% CI 9.5-16.0), 5.8 (95% CI 4.1-7.8), and 5.3 (95% CI 3.5-7.2) months in the original-dose group; and 12.8 (95% CI 11.3-15.3), 5.7 (95% CI 4.4-7.0), and 4.1 (95% CI 3.7-5.7) months in the reduced-dose group. The most common grade 3/4 toxicities were neutropenia (17.9%), anemia (12.8%), and thrombocytopenia (12.8%) in the original-dose group and neutropenia (13.8%) and anorexia (12.3%) in the reduced-dose group. CONCLUSIONS These findings demonstrate CapeOX's efficacy and safety in older AGC patients.

Abstract
BACKGROUND Gastrectomy with D2 dissection and adjuvant chemotherapy is the standard treatment for locally advanced gastric cancer (LAGC) in Asia. However, administering chemotherapy with sufficient intensity after gastrectomy is challenging. Several trials demonstrated the efficacy of neoadjuvant chemotherapy (NAC). However, limited studies explored the feasibility of NAC-SOX for older patients with LAGC. This phase II study (KSCC1801) evaluated the safety and efficacy of NAC-SOX in patients with LAGC aged ≥ 70 years. METHODS Patients received three cycles of SOX130 (oxaliplatin 130 mg/m2 on day 1, oral S-1 40-60 mg twice daily for two weeks every three weeks) as NAC, followed by gastrectomy with lymph node dissection. The primary endpoint was the dose intensity (DI). The secondary endpoints were safety, R0 resection rate, pathological response rate (pRR), overall survival, and relapse-free survival. RESULTS The median age of 26 enrolled patients was 74.5 years. The median DI in NAC-SOX130 was 97.2% for S-1 and 98.3% for oxaliplatin. Three cycles of NAC were administered in 25 patients (96.2%), of whom 24 (92.3%) underwent gastrectomy with lymphadenectomy. The R0 resection rate was 92.3% and the pRR (≥ grade 1b) was 62.5%. The major adverse events (≥ grade 3) were neutropenia (20.0%), thrombocytopenia (11.5%), anorexia (11.5%), nausea (7.7%), and hyponatremia (7.7%). Postoperative complications of abdominal infection, elevated blood amylase, and bacteremia occurred in one patient each. Severe diarrhea and dehydration caused one treatment-related death. CONCLUSIONS NAC-SOX130 is a feasible therapy for older patients, although systemic management and careful monitoring of adverse events are necessary.

Abstract
BACKGROUND The mainstream first-line chemotherapy for advanced/recurrent gastric cancer (ARGC) is combination therapy including platinum-based agents. With the progressive aging of the society, the incidence of gastric cancer in elderly patients is increasing. However, elderly patients cannot tolerate these agents because of renal dysfunction or low quality of life. The KSCC1701 study explored the efficacy and safety of S-1 + ramucirumab in elderly patients with ARGC. PATIENTS AND METHODS Chemotherapy-naive patients aged ≥70 years with ARGC were eligible. Patients received S-1 (40-60 mg twice daily for 4 weeks in 6-week cycles) and ramucirumab (8 mg/kg every 2 weeks) until disease progression. The primary end-point was the 1-year overall survival (OS) rate. The anticipated lower threshold of 1-year survival was set at 40% in light of previous S-1-based regimens. The secondary end-points included progression-free survival (PFS), OS, the overall response rate (ORR) and safety. RESULTS Between September 2017 and November 2019, 48 patients (34 men and 14 women) were enrolled in this study. The median patient age was 77.5 years, and all patients had a performance status of 0 (n = 20) or 1 (n = 28). The 1-year OS rate was 65.2%, which met the primary end-point. The median survival time and median PFS were 16.4 and 5.8 months, respectively. The ORR was 41.9%. The most frequent grade 3/4 (≥15%) adverse events were neutropenia, anorexia and anaemia. CONCLUSION Considering these findings, S-1 + ramucirumab appears to be an excellent treatment option for elderly patients with ARGC. (250 words). This trial has been registered with the Japan Registry of Clinical Trials Registry under the number jRCTs071180066.

Abstract
Gastric (G) and gastro-esophageal junction (GEJ) adenocarcinomas are of the most common and deadly cancers worldwide and affect mainly patients over 70 years at diagnosis. Older age has been associated in gastric cancers with distal tumour location, well-differentiated adenocarcinoma and microsatellite instability and is not identified itself as an independent prognostic factor. As immune checkpoint inhibitors recently changed the landmark of advanced G and GEJ adenocarcinomas treatment, we decided to perform a literature review to define the evidence-level of clinical data in older patients. This work underlined the lasting low -inclusion rate of older patients and -implementation rate of frailty screening tools in clinical trials in G/GEJ carcinomas. In the first-line metastatic setting, two prospective randomized phase III studies have specifically assessed the efficacy of chemotherapy in older patients with HER2-negative gastric cancers, demonstrating the feasibility of reduced dose oxaliplatin-based chemotherapy regimen in this population. Only few data are available in HER2-positive tumors, or in the second-line setting. Furthermore, no specific trial with immune checkpoint inhibitors was performed in older frail patients whereas their benefit/adverse events ratio make them attractive candidates in this patient's population. We conclude that older fit patients can be treated in the same way as younger ones and included in clinical trials. Improving the outcome of older frail patients should be the oncology community next focus by implementing targeted interventions before initiating cancer therapy and designing specific clinical trials. Frailty screening tools and geriatric data collection have to be implemented in routine-practice and clinical trials.

Abstract
The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of gastric cancer (GC) was published in 2016, and covered the management and treatment of local, locoregional, locally advanced and metastatic disease. At the ESMO Asia Meeting in November 2017 it was decided by both ESMO and The Japanese Society of Medical Oncology (JSMO) to convene a special guidelines meeting immediately after the JSMO Annual Meeting in 2018. The aim was to adapt the ESMO 2016 guidelines to take into account the ethnic differences associated with the treatment of metastatic GC in Asian patients. These guidelines represent the consensus opinions reached by experts in the treatment of patients with metastatic GC representing the oncological societies of Japan (JSMO), China (CSCO), Korea (KSMO), Malaysia (MOS), Singapore (SSO) and Taiwan (TOS). The voting was based on scientific evidence and was independent of both the current treatment practices and the drug availability and reimbursement situations in the individual participating Asian countries.

Abstract
It remains unclear whether elderly patients (EPs) with advanced gastric cancer (AGC) benefit from chemotherapy. The aim of the present study was to examine the prognostic factors for EPs with AGC in order to generate a prognosis-predicting scoring system. This single-center retrospective study examined consecutive patients with AGC between April 2012 and July 2017. Risk factors for survival in EPs aged ≥75 years were identified using a Cox proportional hazards model, and a prognostic scoring system was generated and retrospectively evaluated to determine its usefulness for predicting patient prognosis. A total of 61 patients were enrolled as EPs (mean age, 81 years) and compared with 80 non-EPs (mean age, 66 years). The median survival time (MST) was significantly longer for non-EPs compared with that for EPs (3.8 vs. 10.1 months, respectively; P=0.0447). Among the EPs, 29 (48%) received chemotherapy and 32 received best supportive care (BSC). A total of 68 non-EPs (85%) received chemotherapy and 12 non-EPs received BSC. Among EPs with AGC, age-adjusted multivariate analysis revealed that performance status (PS), neutrophil/lymphocyte ratio (NLR)<4, intestinal-type histology and chemotherapy were significant prognostic factors. To predict EPs too frail for chemotherapy prior to treatment, one point was assigned for a PS of 1, diffuse-type histology and NLR≥4, whereas 2 points were assigned for PS≥2, and the point totals for each patient were calculated. A cut-off point of 2 had the best P-value by the log-rank test and was used to divide the patients into low-risk (LoR: Score 0-1) and high-risk (HiR: Score 2-4) groups. The MST of the LoR and HiR groups was 23.6 and 3.6 months, respectively (P<0.001). As regards treatment strategies and risk groups, the LoR chemotherapy group had the best prognosis (P=0.0010), and LoR EPs who were administered chemotherapy had a longer MST (30.3 months) compared with EPs who received BSC (8.7 months). In conclusion, scoring systems using PS, histology and NLR may be useful when considering chemotherapy in EPs with AGC.

A phase II study of combination therapy with oral S-1 and cisplatin in elderly patients with advanced gastric cancer. Gastric Cancer 2018; 21:439-445. [PMID: 28766263 DOI: 10.1007/s10120-017-0753-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2017] [Accepted: 07/17/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND A combination of S-1 and cisplatin is recognized as one of the standard first-line chemotherapy regimens for patients with advanced gastric cancer. However, demographic analyses of pivotal phase III studies have showed that only a minority of treated patients were aged 76 years or older. The purpose of this phase II study was to evaluate the safety and efficacy of combination therapy with S-1 and cisplatin in elderly patients with chemotherapy-naive advanced gastric cancer. METHODS Patients aged 76 years or older received S-1 40 mg/m2 orally twice daily for 21 days and cisplatin 60 mg/m2 intravenously infused at day 8 of each 35-day cycle. Dose modification was performed according to creatinine clearance. The primary endpoint was overall survival (OS). Secondary endpoints included response rate, progression-free survival (PFS), time to treatment failure (TTF), and adverse events. RESULTS A total of 40 patients were enrolled. Median OS was 12.3 months, PFS was 7.8 months, and TTF was 4.3 months. The response rate was 54%. The most common grade 3-4 adverse events were anorexia (25%), neutropenia (23%), hyponatremia (20%), anemia (18%), and febrile neutropenia (8%). No treatment-related death occurred. CONCLUSIONS Combination chemotherapy with S-1 and cisplatin is an effective and well-tolerated regimen for elderly patients with advanced gastric cancer when the dose is adjusted according to renal function.

Abstract
AIM Despite the significant advances in chemotherapy, the prognosis of unresectable or recurrent gastric cancer is still very poor. Given that older adults are likely to have a number of concomitant diseases and an impaired major organ function, cancer chemotherapy in elderly patients requires particular caution. We examined what factors are associated with the overall survival of gastric cancer patients undergoing chemotherapy. METHODS A retrospective chart review of gastric cancer patients receiving oral fluoropyrimidines (N=130) was performed at Nagoya Memorial Hospital over 9 years. The overall survival was calculated from the beginning of chemotherapy until death or the most recent date of follow-up. The Kaplan-Meier method was used to plot survival curves, which were compared using the log-rank test. A multivariate analysis was performed using stepwise Cox proportional hazards models. A comprehensive geriatric assessment was conducted for the elderly patients. The chart review was approved by the ethics committee of Nagoya Memorial Hospital. RESULTS The objective response rate and overall survival did not differ markedly between the patients < 75 years (N=64) and those ≥ 75 years of age (N=28). The addition of lentinan significantly prolonged the survival of the stage 4 gastric cancer patients. In a multivariate analysis of those ≥ 75 years of age, the only independent prognostic factor for the survival was the functional capacity, as measured by the TMIG Index of Competence. CONCLUSIONS This comprehensive geriatric assessment was useful for predicting the longevity of patients with stage 4 gastric cancer ≥ 75 years of age.

Abstract
BACKGROUND S-1 plus cisplatin is a standard regimen for advanced gastric cancer (AGC) in Asia. The ToGA trial established a fluoropyrimidine plus cisplatin and trastuzumab as a standard treatment for human epidermal growth factor receptor 2 (HER2)-positive AGC. In the HERBIS-1 trial, trastuzumab combined with S-1 plus cisplatin showed promising antitumor activity in patients with HER2-positive AGC. However, cisplatin has several important drawbacks, including vomiting and renal toxicity. These disadvantages of cisplatin are prominent in elderly patients. Therefore, we conducted a prospective phase II study of trastuzumab plus S-1 without cisplatin in elderly patients with HER2-positive AGC. METHODS Patients 65 years or older who had HER2-positive AGC received S-1 orally on days 1-28 of a 42-day cycle and trastuzumab intravenously on day 1 of a 21-day cycle. RESULTS A total of 51 patients were enrolled. Two patients were ineligible. The full analysis set thus comprised 49 patients. The median age was 71 years (range 65-85). The confirmed response rate was 40.8% (95% CI 27.1-54.6%), and the null hypothesis was rejected. The median follow-up period was 10.6 months. Median overall survival was 15.8 months. Median progression-free survival was 5.1 months, and time to treatment failure was 4.0 months. Major grade 3 or 4 adverse events included neutropenia (12.0%), anemia (24.0%), diarrhea (10.0%), and anorexia (12.0%). There was one treatment-related death. CONCLUSIONS Trastuzumab in combination with S-1 alone demonstrated promising antitumor activity and manageable toxic effects as well as promising survival results in elderly patients with HER2-positive AGC.

Abstract
An 81-year-old man was admitted with upper abdominal pain and weight loss. Esophagogastroduodenoscopy revealed a large tumor located from the gastric angle to the body. Histological analysis of a biopsy revealed a moderately differentiated adenocarcinoma. Computed tomography revealed metastases in the liver and lung and the patient was subsequently diagnosed with metastatic advanced gastric cancer. He was treated with chemotherapy using S-1 (80 mg/m2) and cisplatin (CDDP) (60 mg/m2). Twenty-two months after chemotherapy, the gastric tumor, and the nodules in the liver and lung, had disappeared. We subsequently diagnosed a clinical complete response. The patient was treated with further S-1 monotherapy for 7 months after complete response assessment. He has lived for more than 7 years since the initial diagnosis without recurrence. Chemotherapy using S-1 and CDDP may be a potent strategy for improving survival in elderly patients with advanced gastric cancer.

Abstract
Purpose To evaluate the efficacy and safety of dose-dense TCF in elderly (≥65 years) compared to younger patients. Methods Safety and efficacy data relative to 119 consecutive patients with locally advanced or metastatic gastric cancer treated at our institution and enrolled in different phase II trials were retrospectively collected. All patients were treatment-naive and received docetaxel 70 mg/m2 day 1, cisplatin 60 mg/m2 day 1, l-folinic acid 100 mg/m2 days 1-2, followed by 5-fluorouracil 400 mg/m2 bolus days 1-2, and then 600 mg/m2 as a 22-hour continuous infusion days 1-2, every 14 days, plus pegfilgrastim 6 mg on day 3. Sixty patients (50%) aged ≥65 years received the same schedule with a dose reduction by 30%. Results A total of 86% of patients were evaluable for response and all for toxicity. In patients aged ≥65 years, we observed an overall response rate of 51%. Median overall survival was 11.2 (95% confidence interval [CI] 7.3-15.1) and 11.8 months (95% CI 9.2-16.2) in elderly and younger patients, respectively. In the elderly patients, the most frequent grade 3-4 toxicities were neutropenia (13%), leukopenia (7%), thrombocytopenia (18%), anemia (3%), and febrile neutropenia (8%); in the younger patients, neutropenia (56%), leucopenia (31%), thrombocytopenia (22%), anemia (15%), and febrile neutropenia (15%). Conclusions Elderly patients can be safely treated with a dose-dense TCF regimen with a 30% dose reduction achieving similar efficacy results as younger patients with lesser toxicity.

Abstract
Gastric cancer patients with main portal vein tumor thrombus usually have a short survival time, owing to its aggressive behavior. Herein, we report a long-surviving case of gastric cancer with main portal vein tumor thrombus. A 78-year-old man presenting with anorexia and body weight loss was diagnosed with gastric cancer. The patient was referred to our hospital for further examination and treatment. Endoscopy revealed a type 3 tumor (8.0 cm in length) in the body of the stomach. Biopsy led to the diagnosis of moderately differentiated adenocarcinoma. Enhanced computed tomography revealed a large tumor thrombus extending from the gastric coronary vein to the portal trunk. A total gastrectomy with lymphadenectomy, splenectomy, and thrombectomy was performed. Postoperative chemotherapy with S-1 was administered for 18 months. The patient died a natural death without recurrence at 49 postoperative months. To the best of our knowledge, the patient was the oldest to be diagnosed with gastric cancer with main portal vein tumor thrombus at diagnosis, who survived >36 months. Although gastric cancer with main portal vein tumor thrombus is a rare occurrence, its prognosis is extremely poor. Intensive surgery and long-term chemotherapy may be effective at improving survival time in these patients.

Abstract
Gastric cancer (GC) is one of the most frequent malignant diseases in the elderly. Systemic chemotherapy showed an improvement of quality of life and survival benefit compared to supportive care alone in patients with advanced GC. Because comorbidities or age-related changes in pharmacokinetics and pharmacodynamics may lead to higher toxicity, however, many oncologists hesitate to recommend elderly patients to receive chemotherapy. Available data suggest that elderly patients with GC are able to tolerate and benefit from systemic chemotherapy to the same extent as younger patients. The age alone should not be the only criteria to preclude effective chemotherapy. However, proper patient selection is extremely important to deliver effective treatment safely. A comprehensive geriatric assessment (CGA) is a useful method to assess life expectancy and risk of morbidity in older patients and to guide providing optimal treatment. Treatment should be personalized based on the nature of the disease, the life expectancy, the risk of complication, and the patient's preference. Combination chemotherapy can be considered for older patients with metastatic GC who are classified as non-frail patients by CGA. For frail or vulnerable patients, however, monotherapy or only symptomatic treatment may be desirable. Targeted agents seem to be promising treatment options for elderly patients with GC considering their better efficacy and less toxicity.

Abstract
BACKGROUND In the GEST study of unresectable pancreatic cancer, S-1 demonstrated non-inferiority compared to gemcitabine, but gemcitabine plus S-1 (GS) did not show superiority over gemcitabine for overall survival (OS). We performed subgroup analysis of these data focused on the efficacy and safety of these regimens as a first-line treatment for elderly patients. METHODS Elderly patients (≥ 70 years, n = 261) treated for unresectable pancreatic cancer (GS: n = 90, S-1: n = 85 and gemcitabine: n = 86) were analysed. RESULTS No significant differences between the GS, S-1, or gemcitabine groups in OS (median: 10.2, 8.0 and 8.5 months, respectively) or objective response rates (27.6%, 25.3% and 14.3%, respectively) were noted. Grade ≥ III adverse haematological events were observed more frequently in GS-treated than in S-1- or gemcitabine-treated elderly patients (p < 0.001 and p = 0.016, respectively). Four of 8 patients aged ≥ 80 years experienced serious adverse events. CONCLUSIONS S-1 and gemcitabine are both efficacious options for treatment of elderly patients with unresectable pancreatic cancer. Conversely, first-line treatment of elderly patients with GS should only be used after careful consideration.

Abstract
Recent clinical trials, such as JCOG9912 and SPIRITS, excluded geriatric patients aged ≥75 years. The clinical significance of intensive chemotherapy for geriatric patients with advanced or recurrent gastric cancer remains unclear. Between 2002 and 2010, 54 consecutive advanced or recurrent gastric cancer patients aged ≥75 years were enrolled in this study. We analyzed the predictors of chemotherapy administration and evaluated the survival benefit of chemotherapy for geriatric patients with advanced or recurrent gastric cancer. A total of 23 geriatric patients received no chemotherapy (GP), whereas the remaining 31 patients were administered chemotherapy (GPC). Of the 54 patients, 20 had severe concomitant illnesses, such as cardiorespiratory disease. Lymph node involvement (P=0.044) and the absence of cardiorespiratory disease (P<0.001) were found to be independently associated with chemotherapy administration. The GPC group exhibited a significantly better prognosis compared to the GP group (median survival time, 19.4 vs. 13.6 months, respectively; P=0.043). GPC patients without cardiorespiratory disease tended to have a better prognosis compared to GP patients without cardiorespiratory disease (P=0.106), whereas there were no significant differences between GP and GPC patients with cardiorespiratory disease. However, administration of chemotherapy was identified as an independent prognostic factor by the Cox proportional hazards model (hazard ratio = 2.609; 95% confidence interval: 1.173-5.761; P=0.019). Therefore, chemotherapy appears to provide a survival benefit in geriatric patients with advanced or recurrent gastric cancer, particularly those without concomitant cardiorespiratory disease.

Abstract
BACKGROUND S-1+cisplatin (CDDP) is the standard treatment for advanced gastric cancer (AGC) in Japan and Korea. However, the usefulness of S-1 based chemotherapy for elderly patients is unclear. Therefore, we conducted a multicenter phase II study of S-1 monotherapy for AGC in elderly patients. MATERIALS AND METHODS Chemotherapy-naïve patients aged over 75 years with AGC were enrolled. The starting dose of S-1 was determined on the basis of body surface area and modified according to the creatinine clearance value. S-1 was administered twice a day during a 4-week period followed by a 2-week rest period. RESULTS Thirty-five patients were enrolled. The response rate (RR) was 14.3% and the median overall survival was 14.6 months. Grade 3 or more severe adverse events consisted of anaemia (3%), neutropaenia (3%), anorexia (3%), and fatigue (6%). There were no treatment-related deaths. CONCLUSION Our study indicates that S-1 monotherapy is safe and well tolerated in chemotherapy-naïve elderly patients with AGC, but exerts limited activity when given using a tailor-made dosing strategy based on renal function.

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
Gastric cancer is known to have a high incidence in several countries around the world, while the treatment of advanced gastric cancer remains a challenge. Recent studies have shown that the antibody bevacizumab, a monoclonal vascular endothelial growth factor antibody, is effective in several solid tumors, while experience regarding its effect on gastric cancer remains limited. An 84-year-old patient with advanced gastric remnant cancer with liver and retroperitoneal lymph node metastasis treated in our hospital benefitted from the use of bevacizumab. Since previous treatment with multiple chemotherapeutic agents resulted in progressive disease (PD), a combined treatment with bevacizumab (intravenously) and low-dose S-1 (orally) was administered. With this individualized treatment, the patient exhibited stable disease (SD) and therapy was maintained for a long period of time as maintenance therapy, with a progression-free survival of ∼25 months prior to PD. The serum tumor marker cancer antigen (CA) 199 decreased from 508.7 to 188.1 ng/ml. No severe side-effects of bevacizumab were observed, with the exception of controlled grade I bleeding gums due to the long-term use of bevacizumab. Although no large-scale clinical trials have been conducted to evaluate the role of bevacizumab in maintenance therapy and second- or even third-line treatment of advanced gastric cancer, we showed that bevacizumab combined with S-1 was effective and well-tolerated by this patient, suggesting that it be considered a viable option for elderly patients with advanced gastric cancer as maintenance therapy and that it provide a novel treatment for advanced gastric cancer. However, additional clinical trials are required to evaluate the exact effects of long-term bevacizumab treatment on patients with advanced gastric cancer.

Abstract
PURPOSE To analyze the clinicopathological features, prognostic factors, treatment efficacy and safety among elderly patients with advanced or metastatic gastric cancer. METHODS Three hundred and nineteen patients aged 65 years and older, diagnosed with advanced or metastatic gastric cancer, were followed and data were retrospectively collected, reviewed and analyzed. RESULTS The elderly patients carried specific clinicopathological characteristics. Body mass index (BMI), number of metastatic lesions, ascites, Karnofsky performance score (KPS), tumor differentiation grade, lactate dehydrogenase (LDH) level, local treatment, and chemotherapy were the independent prognostic factors. Serum LDH level was superior to the serum CEA level in the prognosis of advanced or metastatic gastric cancer in older patients. Cisplatin-based regimen, chemotherapy cycles, metastatic lesions, LDH level, and supraclavicular lymph node metastasis were the independent prognostic factors in 220 patients receiving chemotherapy. The toxicity was mild and tolerable. CONCLUSION KPS, BMI and a well-differentiated histopathology were factors favoring longer survival, whereas elevated serum LDH and a greater number of metastatic lesions were associated with poor prognosis among those elderly patients. Cisplatin-based chemotherapy provided survival benefits and mild toxicity.

Abstract
Combination chemotherapy is a standard treatment approach in advanced gastric cancer. However, combination chemotherapy for advanced gastric cancer is often associated with severe treatment-related toxicities and most oncologists are reluctant to perform combination chemotherapy in patients with a poor clinical condition. We retrospectively investigated the efficacy and tolerability of single-agent chemotherapy in patients with recurrent or metastatic gastric cancer with poor performance status (PS). We reviewed advanced gastric adenocarcinoma patients who received first-line single-agent palliative chemotherapy due to poor PS between June 2006 and December 2010. A total of 125 patients with Eastern Cooperative Oncology Group (ECOG) PS 2-3, whose general condition did not allow combination chemotherapy, were enrolled. Four single agents were used: TS-1 (n=63), paclitaxel (n=42), irinotecan (n=15) and capecitabine (n=5). The median age was 66 years, with a range of 25-81 years. The percent response rate and rate of stable disease (SD) were 19.2 and 35.2%, respectively, giving a disease control rate of 54.4%. The median progression-free survival (PFS) was 3.9 months (95% CI, 2.73-5.06). The median overall survival (OS) was 9.1 months (95% CI, 7.70-10.56) with a 1-year survival rate of 31.2%. Multivariate analysis demonstrated that the independent prognostic factors for OS were chemotherapy regimen (capecitabine) [reference: TS-1, hazard ratio (HR), 5.00; 95% CI, 1.81-13.81; P=0.002], no second-line chemotherapy (HR, 2.3; 95% CI, 1.48-3.57; P=0.001), bone metastasis (HR, 2.73; 95% CI, 1.22-6.09; P=0.014), ECOG PS 3 (HR, 38.10; 95% CI, 13.72-105.78; P=0.001), Glasgow prognostic score (GPS) ≥1 (HR, 1.88; 95% CI, 1.24-2.85; P=0.003) and chemotherapy response [SD + progressive disease (PD) + not evaluable (NE); HR, 2.37; 95% CI, 1.39-4.05; P=0.002)]. First-line single-agent palliative chemotherapy demonstrated a relatively good clinical efficacy for recurrent or metastatic gastric cancer patients with poor PS.

Safety and efficacy of S-1 monotherapy in elderly patients with advanced gastric cancer. Gastric Cancer 2010; 13:245-50. [PMID: 21128060 DOI: 10.1007/s10120-010-0566-z] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2010] [Accepted: 07/06/2010] [Indexed: 02/07/2023]
Abstract
BACKGROUND Although S-1 is effective against advanced gastric cancer (AGC), its efficacy in elderly patients has not yet been investigated sufficiently. We assessed the efficacy and safety of S-1 monotherapy in elderly patients with AGC. METHODS We conducted a retrospective review of the data of 153 patients with unresectable/recurrent gastric adenocarcinoma who received S-1 monotherapy as first-line chemotherapy at our institution. S-1 was administered orally twice daily at the dose of 40 mg/m², on days 1-28, every 6 weeks. We categorized the patients into three groups, the young (≤65 years old), the middle-aged (66-75 years old), and the elderly (≥76 years old); and the drug toxicity, objective responses, progression-free survivals, and overall survivals were compared among the three groups. RESULTS The incidence of leukopenia of grade 3 or greater in the three groups was 7%, 5%, and 13%, and that of anemia was 9%, 18%, and 27%, respectively. In regard to nonhematological toxicities, the incidence of nausea of grade 3 or greater was 3%, 5%, and 13%; that of fatigue was 5%, 11%, and 20%; and that of anorexia was 5%, 6%, and 27%, respectively. As for the treatment efficacy, the objective response rates, median progressionfree survivals, and overall survivals in the young, middle-aged, and elderly groups were 53%, 46%, and 33%; 7.8, 5.6, and 3.9 months; and 16.9, 17.1; and 7.7 months, respectively. CONCLUSION Although S-1 monotherapy showed moderate efficacy in elderly (≥76 years) patients with AGC, patients in this age group showed higher incidences of severe toxicities than the younger patients.

Abstract
PURPOSE We aimed to evaluate the efficacy and safety of gemcitabine/S-1 combination chemotherapy for the treatment of patients with advanced biliary tract cancer. METHODS Patients with histologically or cytologically confirmed unresectable or recurrent biliary tract cancer were eligible for inclusion. The primary endpoint was overall survival. Gemcitabine was administered intravenously at a dose of 1,000 mg/m(2) over 30 min on days 1 and 8, and oral S-1 was administered daily at a dose of 60 mg/m(2) on days 1-14. This schedule was repeated every 3 weeks until disease progression or patient refusal. RESULTS Twenty-five patients were enrolled between October 2007 and January 2009. Eleven patients (44%) had extrahepatic bile duct cancer, 5 (20%) had intrahepatic bile duct cancer, 8 had gallbladder cancer (32%), and 1 (4%) had ampulla of Vater cancer. The median overall survival time was 12.7 months (95% CI, 8.4-23.5 months), and the 1-year survival rate was 52.0% (95% CI, 31.2-69.2%). Of the 23 patients with evaluable target regions, seven patients experienced a partial response, and an overall response rate was 30.4%. The following grade 3-4 hematological toxicities occurred: neutropenia (56%), leukopenia (24%), anemia (8%) and thrombocytopenia (4%). In spite of the high incidence of grade 3-4 neutropenia, no patients developed febrile neutropenia in the present study. The major grade 3-4 non-hematological toxicities were fatigue (8%), anorexia (8%) and diarrhea (4%). CONCLUSIONS Gemcitabine/S-1 combination chemotherapy offered a promising survival benefit with acceptable toxicity in patients with advanced biliary tract cancer.

Abstract
BACKGROUND In patients with adverse events of S-1, the dose is generally reduced or the treatment cycle is shortened. Whether the therapeutic effectiveness of modified regimens is similar to that of the standard dosage remains unclear. METHODS We retrospectively studied patients with gastric cancer who received S-1 on alternate days. RESULTS A total of 266 patients received S-1 on alternate days. In 116 patients, S-1 was initially given at the standard dosage but was switched to alternate-day treatment because of toxicity within 28 days on average. The other 150 patients initially received alternate-day treatment because of poor general condition. In the adjuvant chemotherapy group (n = 96), the 3-year survival rate was 88% in patients with stage II, 73% in stage IIIA, and 67% in stage IIIB who underwent D2 lymph-node dissection. In the palliative surgery group (n = 96), the response rate was 13%, with a median survival time (MST) of 624 days. In patients with unresectable/recurrent disease (n = 74), the response rate was 25%, with an MST of 338 days. Among the 116 patients who initially received treatment on consecutive days, 100% had grade 1, 53% had grade 2, and 5.2% had grade 3 adverse events. When S-1 was switched to alternate-day treatment, toxicity decreased in all patients. In the 266 patients who received alternate-day treatment, 8% had grade 1, 6% had grade 2, and 0% had grade 3 adverse events. CONCLUSION Alternate-day treatment with S-1 may have milder adverse events without compromising therapeutic effectiveness.
