A detailed analysis of the recurrence timing and pattern after curative surgery in patients undergoing neoadjuvant therapy or upfront surgery for gastric cancer. J Surg Oncol 2020; 122:293-305. [PMID: 32350878 DOI: 10.1002/jso.25959] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Accepted: 04/17/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND OBJECTIVES The aim of this study was to determine whether the administration of neoadjuvant therapy (NAD) affects the incidence, timing, and pattern of recurrence in patients treated by curative gastrectomy. METHODS Sixty-nine patients undergoing NAD and R0 gastrectomy were compared with 198 patients undergoing upfront surgery using the propensity score matching (PSM) method. Disease-free survival (DFS), disease-specific survival (DSS), and progression-free survival (PFS) analyses were conducted with a log-rank test and Cox regression. Risk factors for recurrence were assessed by logistic regression. RESULTS Among 69 patients with NAD, 28 (40.6%) experienced recurrence, and signet-ring cell (SRC) carcinoma was the only factor independently associated with recurrence. In the whole sample, NAD did not influence DFS, DSS, rate of recurrence, or PFS. After PSM, the variables associated with DFS were cN1, type of gastrectomy, the presence of SRCs, and the presence of lymphovascular invasion. Variables independently associated with recurrence were cN1, type of gastrectomy, and the presence of SRCs. CONCLUSIONS NAD had no impact on DFS, DSS, or the pattern of recurrence in any patients with gastric cancer. To define a better treatment strategy, future studies should focus on subtypes that do not respond to the current neoadjuvant regimens.

Abstract
BACKGROUND The administration of perioperative chemotherapy represents the Western standard of care for patients with locally advanced gastric cancer. The aim of this study is to determine if the administration of the preoperative component of the perioperative regimen is beneficial in the entire population of patients with locally advanced gastric cancer. METHODS Seventy patients undergoing preoperative therapy were compared with 347 patients undergoing upfront gastrectomy. Survival analyses were conducted with Kaplan-Meier curves and Cox regression. Patients undergoing preoperative therapy or undergoing upfront gastrectomy were matched 1:1 using the propensity score matching (PSM) method, and a survival analysis was conducted on matched patients. A subgroup analysis was conducted by tumor location and Lauren histotype. RESULTS In patients undergoing preoperative therapy, factors significantly associated with survival were T and N downstaging, type of gastrectomy, resection status and Lauren histotype. Preoperative therapy was not significantly associated with survival (p = 0,761 before PSM and p = 0,519 after PSM). After PSM, the independent variables significantly associated with survival were type of gastrectomy, type of lymphadenectomy, R status and postoperative therapy. In the subgroup analysis, preoperative therapy demonstrated a selective association with the location of the tumor (p = 0,055) and with Lauren intestinal histotype (p = 0,002). CONCLUSIONS Preoperative therapy had a non-significant impact on survival in the entire population of gastric cancer patients. The advantage of preoperative therapy seems to be limited to patients with proximal tumors and an intestinal histology. Future studies should better evaluate the diverse response of the different phenotypes of gastric cancer to preoperative therapy.

Abstract
Neoadjuvant platin-based therapy is accepted as a standard therapy for advanced esophageal adenocarcinoma (EAC). Patients who respond have a better survival prognosis, but still a significant number of responder patients die from tumor recurrence. Molecular markers for prognosis in neoadjuvantly treated EAC patients have not been identified yet. We investigated the epidermal growth factor receptor (EGFR) in prognosis and chemotherapy resistance in these patients. Two EAC patient cohorts, either treated by neoadjuvant cisplatin-based chemotherapy followed by surgery (n=86) or by surgical resection (n=46) were analyzed for EGFR protein expression and gene copy number. Data were correlated with clinical and histopathological response, disease-free and overall survival. In case of EGFR overexpression, the prognosis for neoadjuvant chemotherapy responders was poor as in non-responders. Responders had a significantly better disease-free survival than non-responders only if EGFR expression level (p=0.0152) or copy number (p=0.0050) was low. Comparing neoadjuvantly treated patients and primary resection patients, tumors of non-responder patients more frequently exhibited EGFR overexpression, providing evidence that EGFR is a factor for indicating chemotherapy resistance. EGFR overexpression and gene copy number are independent adverse prognostic factors for neoadjuvant chemotherapy-treated EAC patients, particularly for responders. Furthermore, EGFR overexpression is involved in resistance to cisplatin-based neoadjuvant chemotherapy.

Abstract
BACKGROUND Neoadjuvant chemotherapy may improve outcomes in gastric cancer. Tumor responses can be evaluated with RECIST, Japanese Classification of Gastric Carcinoma (JCGC), and histological criteria. These approaches have not yet been compared. METHODS We analyzed two phase II trials of neoadjuvant chemotherapy using S-1 plus cisplatin. JCOG0210 included patients with linitis plastica and large ulcero-invasive tumors, whereas JCOG0405 comprised those with para-aortic or bulky lymph node metastases. Radiologic evaluations were conducted using RECIST in JCOG0405 and JCGC criteria in JCOG0210, because the latter included many patients without measurable lesions. A histological responder was defined as a patient in whom one third or more of the tumor was affected. The hazard ratios (HR) for death between responders and non-responders and response rate differences between short- and long-term survivors were estimated. RESULTS In JCOG0210 (n = 49), HR was 0.54 in JCGC responders (P = 0.059) and 0.40 in histological responders (P = 0.005). The difference in response rates between short- and long-term survivors using histological criteria (34 %, P = 0.023) was greater than that using JCGC criteria (24 %, P = 0.15). In JCOG0405 (n = 51), HR was 0.67 in RECIST responders (P = 0.35) and 0.39 in histological responders (P = 0.030). In short- and long-term survivors, respectively, RECIST response rates were 62 and 67 % (P = 0.77), whereas histological response rates were 33 and 63 % (P = 0.048). CONCLUSIONS Histological criteria showed higher response assessment validity than RECIST or JCGC criteria and yielded the best surrogate endpoint for overall survival.

Long-term outcomes of trimodality treatment for squamous cell carcinoma of the esophagus with cisplatin and/or 5-FU: more than 20 years' experience at a single institution. Strahlenther Onkol 2015; 190:1133-40. [PMID: 25015426 DOI: 10.1007/s00066-014-0711-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2014] [Accepted: 06/09/2014] [Indexed: 02/06/2023]
Abstract
PURPOSE The purpose of this article is to report the outcome of neoadjuvant radiochemotherapy (N-RCT) + surgery in patients with squamous cell carcinoma of the esophagus at a single institution. METHODS We retrospectively reviewed data from patients who were referred to our department for N-RCT. From 1988–2011, 103 patients were treated with N-RCT with cisplatin and/or 5-fluorouracil (5-FU). Group 1: (n = 55) from 1988–2006 with 39.6–40 Gy and 5-FU with (n = 17) or without cisplatin (n = 38). Group 2: from 2003–2010 with 44–45 Gy and 5-FU with (n = 40) or without cisplatin (n = 8). All patients underwent radical resection with reconstruction according to tumor location and 2-field lymph node dissection. The degree of histomorphologic regression was defined as grade 1a (pCR, 0 % residual tumor), grade 1b (pSTR, < 10 % residual tumor), grade 2 (10–50 % residual tumor), and grade 3 (> 50 % residual tumor). RESULTS Median follow-up time from the start of N-RCT was 100 months (range 2–213 months). The median overall survival (OS) for the whole cohort was 42 months and the 5-year OS was 45 ± 5 %. In the multivariate analysis, worse ECOG performance status (p < 0.001), weight loss > 10 % before the start of the N-RCT (p = 0.025), higher pT category (p = 0.001), and grade 2/3 pathologic remission (p < 0.001) were significantly associated with a poor OS. PCR and pSTR rates for group 1 were 36 % and 18 % compared to 53 % and 22 % for group 2 (p = 0.011). There was a tendency for a better outcome in group 2 patients without statistical significance. The 5-year OS, disease-free survival and recurrent-free survival were 36 ± 7 %, 35 ± 6, and 36 ± 7 % for group 1 and 55 ± 7, 49 ± 7, and 53 ± 7 in group 2 (p = 0.117, p = 0.124, and p = 0.087). There was no significant difference between the two groups considering the postoperative morbidity and mortality. CONCLUSION Higher radiation doses and more use of simultaneous cisplatin lead to higher pathologic response rates to N-RCT and may be associated with better survival outcomes. Prospective controlled trials are needed to assess the true value of intensified N-RCT regimens.

Cisplatin- vs. oxaliplatin-based radiosensitizing chemotherapy for squamous cell carcinoma of the esophagus: a comparison of two preoperative radiochemotherapy regimens. Strahlenther Onkol 2014; 190:987-92.

Abstract
PURPOSE To compare the outcomes of two neoadjuvant radiochemotherapy (N-RCT) regimens for squamous cell carcinoma of the esophagus (ESCC). METHODS The standard N-RCT regimen for ESCC at our institution between 2002 and 2011 was a total dose of 45 Gy (1.8-Gy fractions) with concomitant cisplatin (20 mg/m(2), days 1-5 and 29-33) and 5-fluorouracil (5-FU; 225 mg/m(2), 24 h continuous infusion on days 1-33). During the same period, a phase I/II study comparing the standard ESCC N-RCT protocol with a regimen identical except for the replacement of cisplatin with weekly oxaliplatin (40-50 mg/m(2)) was performed at our center. The standard regimen was used to treat 40 patients; 37 received the oxaliplatin regimen. All patients subsequently underwent radical resection with reconstruction according to tumor location and two-field lymph node dissection. RESULTS Median follow-up time from the start of N-RCT was 74 months (range 3-116 months). The two patient groups were comparable in terms of demographic and baseline tumor characteristics. R0 resection was achieved in 37/39 patients (95 %) in the cisplatin-based N-RCT group, compared to 24/37 (65 %) in the oxaliplatin-based group (p = 0.002). A pathological complete response (pCR) was seen in the resection specimens from 18/39 patients (46 %) in the cisplatin-based N-RCT group and in 8/37 (22 %) oxaliplatin-group patients. In the cisplatin group, 2- and 5-year overall survival (OS) rates were 67 ± 8 % and 60 ± 8 %, respectively (median OS 103 months), compared to 38 ± 8 % and 32 ± 8 %, respectively, for the oxaliplatin group (median OS 17 months; hazard ratio, HR 0.452; 95 % confidence interval, CI 0.244-0.839; p = 0.012). CONCLUSION Oxaliplatin-based N-RCT resulted in poorer outcomes in ESCC patients and should not routinely replace cisplatin-based N-RCT.

Abstract
Chemotherapeutic drugs kill cancer cells, but it is unclear why this happens in responding patients but not in non-responders. Proteomic profiles of patients with oesophageal adenocarcinoma may be helpful in predicting response and selecting more effective treatment strategies. In this study, pretherapeutic oesophageal adenocarcinoma biopsies were analysed for proteomic changes associated with response to chemotherapy by MALDI imaging mass spectrometry. Resulting candidate proteins were identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and investigated for functional relevance in vitro. Clinical impact was validated in pretherapeutic biopsies from an independent patient cohort. Studies on the incidence of these defects in other solid tumours were included. We discovered that clinical response to cisplatin correlated with pre-existing defects in the mitochondrial respiratory chain complexes of cancer cells, caused by loss of specific cytochrome c oxidase (COX) subunits. Knockdown of a COX protein altered chemosensitivity in vitro, increasing the propensity of cancer cells to undergo cell death following cisplatin treatment. In an independent validation, patients with reduced COX protein expression prior to treatment exhibited favourable clinical outcomes to chemotherapy, whereas tumours with unchanged COX expression were chemoresistant. In conclusion, previously undiscovered pre-existing defects in mitochondrial respiratory complexes cause cancer cells to become chemosensitive: mitochondrial defects lower the cells' threshold for undergoing cell death in response to cisplatin. By contrast, cancer cells with intact mitochondrial respiratory complexes are chemoresistant and have a high threshold for cisplatin-induced cell death. This connection between mitochondrial respiration and chemosensitivity is relevant to anticancer therapeutics that target the mitochondrial electron transport chain.

Abstract
BACKGROUND Preoperative treatment is a promising strategy for improving long-term outcomes in advanced esophageal cancer. Two tumor response evaluation criteria for preoperative treatment are available: response evaluation criteria in solid tumors (RECIST) and histological criteria. This prospective study aimed to identify which was a better surrogate end point for survival in the preoperative setting. METHODS We analyzed all eligible patients (n=164) from the preoperative treatment group in a phase III trial comparing preoperative versus postoperative 5-fluorouracil plus cisplatin for clinical stage II or III esophageal cancer. Intercriteria reliability was evaluated with the proportion of agreement and the kappa coefficient. For validity analyses, hazard ratios (HR) of response to nonresponse and differences in response rates between short- and long-term survivors were evaluated. RESULTS The clinical and histological response rates were 37.8% (62 of 164) and 20.1% (33 of 164), respectively. The proportion of agreement for response to nonresponse between the 2 criteria was 70.3%, and the kappa coefficient was 0.34. The HR for death in patients with histological response (0.22, 95% confidence interval 0.09-0.55, P<0.001) was lower than for those with RECIST response (0.55, 95% confidence interval 0.33-0.91, P=0.018). The difference in response rates between short- and long-term survivors according to histological criteria (27 vs. 7%, P<0.001) was larger than with RECIST (42 vs. 30%, P=0.13). CONCLUSIONS Intercriteria agreement was relatively low, and histological criteria yielded more valid assessments of response than RECIST. Histological response rate seemed to be the better surrogate end point of survival in the preoperative setting.

Abstract
BACKGROUND Based on a phase I study showing the feasibility of combining of oxaliplatin, cisplatin, and 5-fluorouracil (5-FU) (OCF) with radiation therapy (RT) in esophageal cancer, the efficacy of this regimen in esophageal, gastroesophageal (GE), and gastric (G) cancer was assessed in this phase II multicenter study. PATIENTS AND METHODS Patients with resectable tumors were eligible. Treatment included two cycles of oxaliplatin 85 mg/m(2), cisplatin 55 mg/m(2), and continuously infused 5-FU 3 g/m(2) in 96 h and concurrent RT (45 Gy), followed by surgery after 6-8 weeks. Primary end point was complete pathologic response (pCR). RESULTS Forty-one patients were enrolled. Tumor location was esophagus 39% (squamous 10/adenocarcinoma 6), GE junction 32%, and stomach 29%. G3-G4 adverse events included asthenia (27%) and neutropenia (14%). One toxic death occurred. Thirty-one patients (75.6%) underwent surgery (R0 in 94%). Pathologic response was achieved in 58% of patients, with pCR in 50% and 16% of esophageal and GE/G cancer, respectively. pCR was achieved in 67% of squamous cell carcinoma. Survival: median follow-up, 50.4 months; median progression-free survival and overall survival were 23.2 and 28.4 months, respectively. CONCLUSION Preoperative OCF plus RT showed an acceptable toxicity and promising activity especially in squamous cell esophageal cancer.

Abstract
BACKGROUND While it is suggested that more than 15 lymph nodes (LNs) should be evaluated for accurate staging of gastric cancer, LN yield in western countries is generally low. The effect of preoperative chemotherapy on LN yield in gastric cancer is unknown. The aim of the present study is to determine whether preoperative chemotherapy is associated with any difference in the number of LNs obtained from specimens of patients who underwent curative surgery for gastric adenocarcinoma. PATIENTS AND METHODS In 1205 patients from Memorial Sloan-Kettering Cancer Center (MSKCC) and 1220 patients from the Netherlands Cancer Registry (NCR) who underwent a gastrectomy with curative intent for gastric adenocarcinoma without receiving preoperative radiotherapy, LN yield was analyzed, comparing patients who received preoperative chemotherapy and patients who received no preoperative therapy. RESULTS Of the 2425 patients who underwent a gastrectomy, 14% received preoperative chemotherapy. Median LN yields were 23 at MSKCC and 10 in the NCR. Despite this twofold difference in LN yield between the two populations, with multivariate Poisson regression, chemotherapy was not associated with LN yield of either population. Variables associated with increased LN yield were institution, female sex, lower age, total (versus distal) gastrectomy and increasing T-stage. CONCLUSIONS In this patient series, treatment at MSKCC, female sex, lower age, total gastrectomy and increasing primary tumor stage were associated with a higher number of evaluated LNs. Preoperative chemotherapy was not associated with a decrease in LN yield. Evaluating more than 15 LNs after gastrectomy is feasible, with or without preoperative chemotherapy.

Abstract
INTRODUCTION Several studies have proven an ameliorated prognosis after a neoadjuvant therapy for locally advanced Barrett's carcinoma in case of response. The necessary amount of neoadjuvant chemotherapy within a multimodal therapy concept with following oesophageal resection has never been evaluated so far. METHODS The clinical course of 122 patients with Barrett's carcinoma, who all underwent a neoadjuvant chemotherapy with cisplatin, five fluorouracil and leucovorin and following oesophagectomy, was reviewed. The pretherapeutic clinical and postoperative histopathological staging, histopathological response, clinical course, recurrence rates and long-term survival were retrospectively analysed and compared to the data of 30 patients, who were included in the same multimodal therapy concept, but who had to cease the chemotherapy early because of toxicity. RESULTS Postoperative pathological staging showed that the response rate correlates with the N and R status. The responding patients benefit from longer survival. Comparing the two subgroups, we could not find a significant difference in response rate, tumour staging, resection rate, long-term survival or pattern of recurrent disease. However, postoperative morbidity and mortality did not correlate with severe chemotherapy-induced toxicity. CONCLUSIONS This is the first study on the necessary number of chemotherapy cycles in terms of a neoadjuvant therapy for Barrett's carcinoma. We could show a similar downstaging effect, a good histopathological response and a comparable ameliorated long-term survival of patients with one compared to patients with three chemotherapy cycles. A biological selection seems to determine the course of the disease already at this early stage.

Abstract
BACKGROUND We performed short-term neoadjuvant chemotherapy (s-NAC) to examine whether anticancer drugs can change the proliferative ability of cancer cells in gastric cancer patients. METHODS Chemotherapy was performed for 72 h before gastrectomy in 63 gastric cancer patients. Patients were classed into four groups: Group F, 16 cases who received a single administration of 5-fluorouracil (5-FU); Group C, 15 cases who received a single administration of cis-diamminedichloroplatinum (CDDP; cisplatin); Group FC, 16 cases who received both 5-FU+CDDP; and a Control group, 16 cases who did not receive chemotherapy. We reviewed neoadjuvant biopsy tissue and gastric cancer tissue delivered by operation in these cases. The TUNEL method and immunohistochemistry with an anti-MIB-1 antibody were used to evaluate cellular apoptosis and proliferative ability, respectively. The apoptotic index (AI) and an MIB-1 index (MI) were also calculated. RESULTS There were no differences in AI or MI in biopsy tissue between the groups. The AI of gastric cancer tissue in Group FC was significantly higher than in the other groups (P < 0.01). The MI of Group FC was significantly lower than in the other groups (P < 0.05). In addition, after s-NAC operation there was a significant inhibition of proliferative potency and an induction of apoptosis in Group FC. CONCLUSION Combination of CDDP and 5-FU reduced proliferative potency and increased cellular apoptosis in gastric cancer cells.

Abstract
PURPOSE In locally advanced (uT(3), N(+)) adenocarcinomas of the esophagus, neoadjuvant chemotherapy improves patient outcome. However, only a subgroup of patients responds. Therefore, in the present study, we evaluated whether the response to neoadjuvant chemotherapy can be predicted by a pretreatment tumor biopsy analysis. EXPERIMENTAL DESIGN Biopsies of 47 patients with locally advanced (uT(3), N(+)) adenocarcinoma of the esophagus were obtained during primary staging. All patients underwent neoadjuvant chemotherapy with cisplatin, 5-fluorouracil, and leucovorin and subsequent resection of the esophagus. Biopsies were used for microarray analysis. The predominance of tumor cells within the specimens was >70%. Affymetrix U133 plus 2.0 gene chips with 54675 probe sets were used. A statistical comparison of patients responding to chemotherapy versus nonresponding patients was done. All patients were examined with immunohistology against Ephrin B3 receptor and Ki-67. RESULTS A total of 86 genes were at least 2-fold differentially regulated comparing responding with nonresponding adenocarcinomas of the esophagus. The predominant genes encoded for the regulation of the cell cycle, transduction, translation, cell-cell interaction, cytoskeleton, and the signal transduction. The strongest difference was seen for the Ephrin B3 receptor. This result could be confirmed by immunhistology. A statistical significant correlation between the Ephrin B3 receptor, chemotherapy response, pathologic staging, and grading could be shown. CONCLUSIONS There were significant differences in the gene profile between patients with adenocarcinoma of the esophagus responding to neoadjuvant chemotherapy compared with nonresponding patients. This suggests that it could be possible to characterize patients responding to chemotherapy even before starting the treatment using customized microarray analysis.

Abstract
BACKGROUND Perioperative chemotherapy is considered an effective treatment option for patients with gastric carcinoma. We report the results after a 7-year follow-up of a study aimed at evaluating a perioperative chemotherapy protocol in a group of patients with locally advanced gastric cancer (LAGC). METHODS Between February 1996 and May 2000, 24 patients with LAGC underwent D2-gastrectomy after three preoperative cycles of chemotherapy (Epidoxorubicin, Etoposide, Cisplatinum). Three further cycles were planned after surgery. Differences among groups were evaluated using the chi-square test. Survival rate was calculated after a 7-year follow-up, and differences were assessed using the log-rank test. Multivariate analysis was performed using the Cox proportional hazard model. RESULTS A total of 24 patients received preoperative chemotherapy and underwent surgical resection. Of these, 17 (71%) received postoperative treatment. The main toxicity was grade 3-4 neutropenia. Curative resection (R0) was achieved in 83.3% of patients. No pathologic complete responses were documented, but tumor downstaging was obtained in 10 of 24 patients (41.7%). Overall median survival was 40 months, and 7-year survival rate was 46%. At univariate and multivariate analysis, R0 resection and tumor diameter were the most important prognostic factors. CONCLUSION Long-term results in our series show a survival benefit for LAGC patients treated by perioperative chemotherapy and D2-gastrectomy when compared with previously studied controls who had surgery with postoperative chemotherapy alone. The high rate and prognostic impact of R0 resection in this study stressed the role of the therapy during the preoperative phase.

Abstract
S-1, a novel oral fluoropyrimidine, is an effective therapeutic agent for gastric cancer. Herein, we report a case with locally advanced gastric cancer that achieved a curative resection after S-1 monotherapy as neoadjuvant treatment. A 68-year-old man was diagnosed with gastric cancer and massive lymphadenopathy involving the perigastric, celiac axis and splenic hilum. His clinical stage was cT3N2H0P0M0. Considering his relatively poor performance (ECOG 2, severe weight loss) and advanced age, we started the patient on S-1 monotherapy at a dose of 35 mg/m2 bid for 4 consecutive weeks followed by a 2-week rest. Follow-up study after 4 treatment cycles revealed disappearance of the lymphadenopathy of the perigastric and celiac axis with diminished extension of the stomach mass. The patient had a partial response (PR) with a 72% tumor reduction, according to the Response Evaluation Criteria in Solid Tumors (RECIST). His performance status was improved to an ECOG 1 and he gained 7 kg. A curative (R0) resection was achieved with a radical total gastrectomy and D2 dissection. The pathological stage was pT3N2M0, stage IIIB. In conclusion, S-1 neoadjuvant chemotherapy aided in the treatment of gastric cancer in this patient.

Abstract
AIMS Aim of this study is the evaluation of the effects induced by neoadjuvant chemotherapy (NACT) and its impact on survival on a series of locally advanced gastric carcinomas. METHODS Downstaging was assessed comparing pre-treatment clinical and laparoscopic staging with post-operative pathologic staging on 30 consecutive patients who completed a 3-year follow-up. Tumor downstaging and the grade of pathologic response were included in a statistical correlation between tumor regression induced by NACT and 3-year survival. RESULTS In this series tumor downstaging was obtained in 13 out of 30 patients. After the completion of 3-year follow-up, overall survival was >37.5months with an overall survival rate of 56.7%; this figure reached up to 70.8% in those cases who benefited from a R0-resection (24/30 patients: R0-resection rate 80.0%). CONCLUSIONS In this study the 3-year survival for locally advanced gastric cancer treated by NACT prior to "D2" surgical resection, compares favourably with historical series treated by surgery alone. Patients who obtained T-downstaging and subsequently benefited from a R0-resection had a definitely better chance of cure, according to a complete 3-year follow-up.

Abstract
BACKGROUND AND OBJECTIVES Neoadjuvant chemotherapy is increasingly considered an effective treatment option for patients with gastric carcinoma. Aim of the study is to evaluate the prognostic significance of the pathological response and of known prognostic factors in a group of accurately staged locally advanced gastric cancer (LAGC) patients. METHODS Thirty-three patients with LAGC, staged by laparoscopy, underwent D2-gastrectomy after preoperative chemotherapy. Survival was calculated by Kaplan-Meier method and differences were assessed by the Log-rank and Breslow test. Multivariate analysis was performed using the Cox proportional hazard model in backward stepwise regression. RESULTS Curative resection (R0) was achieved in 81.8% of patients. A complete or subtotal pathological response was documented in 3 and 6%, respectively. Nineteen out of thirty-three (57.6%) patients were alive and 16 of them were free of relapse at last follow-up. Survival rates were 81, 67, and 59% at 12, 24, and 36 months, respectively. At univariate and multivariate analysis, only R0 resection was found to be an independent prognostic factor. CONCLUSIONS In the current study, R0 resection is the most important prognostic factor for resectable LAGC; according to our results we feel encouraged to consider neoadjuvant chemotherapy a promising modality for increasing the R0-percentage of gastric carcinoma patients who could benefit from a curative surgery.

Abstract
Following surgical resection locally advanced oesophageal carcinomas exhibit a bad prognosis and therefore neoadjuvant therapeutic strategies were developed. Because success of therapy is associated with the extent of tumor regression in this context, the introduction of objective histopathological criteria seems to be very important. This study included 67 patients with oesophageal carcinomas (cT2-cT4 cNx cM0) that were treated with a cisplatin- and 5-fluorouracil-containing simultaneous radiochemotherapy. In 43 patients squamous cell, in 24 cases adenocarcinomas were diagnosed. After completion of therapy, a surgical resection and a histopathological examination of the tissue specimens were performed. The extent of tumor regression was histologically evaluated and therapy-induced alterations were graded semiquantitatively. Thereby, a significantly favorable prognosis was observed in the group of patients that showed a regression of carcinomas of 90% or more. Additionally, the extent of a resorptive-histiocytic reaction, giant cells and lymphocytic infiltrates correlated with the grade of regression. These results underline the importance of an exact examination and histomorphological evaluation of the response for the assessment of survival probability after neoadjuvant radiochemotherapy of oesophageal carcinomas.

Abstract
AIMS Gastric cancer in Western countries is often diagnosed in an advanced stage and prognosis is poor. We performed a randomised trial with pre-operative FAMTX vs. surgery alone in order to evaluate the effect of pre-operative chemotherapy on resectability and survival. METHODS Patients with proven adenocarcinoma of the stomach were randomised to receive four courses of chemotherapy using 5-Fluorouracil, doxorubicin and methotrexate (FAMTX) prior to surgery or to undergo surgery alone. RESULTS Fifty-nine patients were randomised; 29 patients were allocated to the FAMTX regimen prior to surgery and 30 patients had surgery alone. Resectability rates were equal for both groups. Complete or partial response was registered in 32% of the FAMTX group. With a median follow-up of 83 months the median survival since randomisation is 18 months in the FAMTX group vs. 30 months in the surgery alone group (p=0.17). CONCLUSIONS This trial could not show a beneficial effect of pre-operative FAMTX. Until large randomised studies prove otherwise, adequate surgery without delay is the best treatment for operable gastric cancer.

Abstract
BACKGROUND Neoadjuvant chemotherapy has shown some success in the treatment of gastric carcinoma, but objective parameters for measuring its effects are lacking. The authors performed the current study to determine which histomorphologic features are correlated with patient prognosis after chemotherapy. METHODS Thirty-six patients with gastric carcinoma were treated with a combination of etoposide, doxorubicin, and cisplatin. The entire tumor beds of the specimens were evaluated histologically and compared with specimens treated with surgery alone. Thirty-four patients were available for survival analysis (follow-up period, 60-130 months). RESULTS None of the 36 patients had complete tumor regression, 4 patients had marked regression (less than 10% viable tumor), 9 patients had regression to 10-50% remaining viable tumor, and 23 patients had more than 50% viable tumor remaining. Currently, 9 patients are still alive (5-year survival rate, 27%). Tumor regression was found to be correlated significantly with survival (P = 0.01), but tumor size (P = 0.002) and lymphatic vessel invasion (P = 0.003) were better predictors of prognosis. CONCLUSIONS Histologic tumor regression grade is an objective measure of the effects of neoadjuvant chemotherapy in patients with gastric carcinoma, but its accuracy may be improved by adding additional staging variables such as tumor size and lymphatic vessel involvement.

Abstract
The aim of this study was to evaluate the effect of preoperative chemotherapy on metastatic lymph nodes and on the outcome of patients who underwent esophagectomy for advanced squamous cell carcinoma of the esophagus. Fifty-nine patients with potentially resectable squamous cell carcinoma of the esophagus were studied. Twenty patients (group A) were treated by preoperative chemotherapy with cisplatin, 5-fluorouracil, and leucovorin, followed by surgery. Thirty-nine patients underwent surgery alone (group B). A total of 2591 resected lymph nodes were histologically evaluated for metastasis and the effect of chemotherapy. The metastasis rate in the resected lymph nodes, the number of metastatic lymph nodes, and outcome of the patients were statistically analyzed between groups. In group A, the clinical and pathological response rates were 75% and 75% respectively. The metastasis rate in the resected lymph nodes was significantly higher in group B (P < 0.01). The mean number of metastatic lymph nodes was significantly lower in group A (P < 0.05). Furthermore, the mean number of metastatic lymph nodes was significantly lower in the chemotherapy responders than in non-responders. The survival rate in group A was better than in group B (P = 0.07). Preoperative chemotherapy reduced the number of metastatic lymph nodes and may contribute to improving the outcome of the patients who have undergone esophagectomy for squamous cell carcinoma of the esophagus.

Abstract
AIM: To assess the safety and efficacy of different intravenous chemotherapeutic regimens in patients with gastric carcinomas who had undergone gastrectomy.
METHODS: A meta-analysis of all the relevant randomized controlled trials (RCTs) was performed. Language was restricted to Chinese and English. RCTs were identified from Medline and Embase (1980-2001/4), and Chinese Bio-medicine Database (1990-2001/1). Literature references were checked at the same time. We included randomized and quasi-randomized trials comparing the efficacy of intravenous chemotherapy after gastrectomy with that of surgery alone in patients with confirmed gastric carcinomas who had undergone gastrectomy. Selection criteria were: randomized or quasi-randomized trials with following-up results; Trials could be double-blind, single-blind or not blind; Chemotherapy groups were given intravenous chemotherapy after gastrectomy without neo-adjuvant chemotherapy, intraperitoneal hyperthermic perfusion, radiotherapy or chemoimmunotherapy; Controlled group included those receiving gastrectomy alone. The following data were extracted: the number of survival and death by the end of the follow-up; the different agents and doses of the intravenous chemotherapy; the baseline of the chemotherapy group and the controlled arm; the serious adverse events; the statistical consideration; cost-effectiveness analysis. The statistical analysis was performed by RevMan4.1 software which was provided by the Cochrane Collaboration. A P value of < 0.05 was considered statistically significant. Meta-analysis was done with random effects model. Heterogeneity was checked by chi-square test. Sensitivity analysis was performed by excluding the trials in which Jadad-scale was only 1 score. The result was expressed with odds ratio (OR) for the categorical variable.
RESULTS: Fourteen trials involving 4543 patients were included. Meta-analysis was done with random effects model Heterogeneity and sensitivity analysis were performed also. The effect of intravenous chemotherapy after gastrectomy was better than surgery alone (odds ratio 0.56, 95%CI 0.40-0.79). There was a significant difference between the two groups by u-test (P = 0.0008). Sensitivity analysis revealed the same difference (odds ratio 0.81, 95%CI 0.70-0.94). Of fourteen trials, only three studies were of high quality according to the Jadad-scale (with three score). There was one meta-analysis trial and the others, about ten trials, were of low quality. There was no trial which mentioned sample-size calculation, allocation concealment, intention-to-treat analysis. Most of the trials didn’t describe the blind-procedure. There were five trials which detailed the side-effects according to the toxicity grade by WHO standard. The side-effects halting treatment were haematologic and biochemical toxicity, debilitating nausea and vomiting. There were two patients died of chemotherapy toxicity.
CONCLUSION: Based on the review, intravenous chemotherapy after gastrectomy may have positive treatment effect on gastric cancer. However, the evidence is not strong because of the general low methodologic quality of the RCTs. Therefore, we can’t make the conclusion that intravenous chemotherapy after gastrectomy may have better treatment effect on gastric cancer than that of surgery alone. Rigorously designed, randomised, double-blind, placebo-controlled trials are required.

Abstract
Micrometastasis (MM) and tumor cell microinvolvement (TCM) in the lymph node were immunohistochemically evaluated using the cytokeratin (CK) antibody between a surgery group (n=20; 929 lymph nodes) and a chemotherapy group (n=20; 1052 lymph nodes). The incidence of MM+/-TCM in the surgery and chemotherapy groups was 50.0 (10/20) and 55.0% (11/20), respectively. Limiting the analysis to TCM alone revealed that the incidence in the chemotherapy group (10.0%; 2/20) was significantly lower than that in the surgery group (40.0%; 8/20; P=0.032). Preoperative chemotherapy in this regime was not effective, except for some patients with TCM alone.

Abstract
BACKGROUND AND OBJECTIVES The relationship between the number of lymph nodes examined and the outcome in patients with node-negative (N(-)) gastric cancer was studied. We compared N(-) patients to those with nodal involvement (N(+)) to identify clinicopathologic characteristics of N(-) gastric cancer. Finally, we evaluated outcome indicators in this group of patients. METHODS Of 367 patients, 130 (35.4%) were N(-). These patients were stratified according to the main prognostic variables, to assess differences with N(+) cases. A statistical analysis using the Cox model was performed to estimate outcome indicators. RESULTS N(-) gastric carcinomas were significantly different from N(+) cases in terms of tumor depth and site, TNM stage, grading, residual disease, and vessel involvement. The overall 5-year survival rate was 72%. It was 82% in those patients with more than 15 nodes retrieved and 59% in the others. Serosal involvement, residual disease, and poor differentiation were independent prognostic factors. CONCLUSIONS The clinicopathologic factors and outcome of N(-) cases were similar to those of early gastric cancer. At least 15 examined nodes appears to be necessary to define a case as N(-). The prognostic value of D2 lymphadenectomy in N(-) patients suggests a biologic role of micrometastases.
