Transl Oncol 2023; 29:101626. [PMID: 36689863 PMCID: PMC9876974 DOI: 10.1016/j.tranon.2023.101626] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 11/18/2022] [Accepted: 01/13/2023] [Indexed: 01/22/2023] Open
Abstract
Increasing evidence has demonstrated that Ctr1 plays a crucial role in the regulation of cisplatin uptake in a variety of tumors. The purpose of this study was to investigate its role in mediating cisplatin sensitivity in ESCC cells. Immunohistochemistry (IHC), In situ hybridization (ISH) and semi-quantitative RT-PCR were used to detect Ctr1 expressions in ESCC tissues. qRT-PCR and Western blot was performed to investigate the levels of Ctr1 mRNA and protein in ESCC cells. CCK-8, Flow cytometry and Transwell chamber assay were carried out to examine cell proliferation, apoptosis, migration and invasion abilities in ESCC cells. We found that ESCC tissues and cells had higher Ctr1 level than normal tissues and Het-1A cell. Ctr1 expression was correlated with histological grade, invasion depth, TNM staging and lymph node metastasis in ESCC patients. Ctr1 depletion reduced the suppressive role of proliferation, migration and invasion as well as the inductive role of cell apoptosis and Caspase-3 activity evoked by cisplatin, whereas Ctr1 upregulation combined with cisplatin exerted the synergistic role in regulation of proliferation, apoptosis, Caspase-3 activity, migration and invasion in ESCC. In conclusion, Ctr1 is implicated in ESCC development and progression and its expression may be a novel predictor for assessment of cisplatin sensitivity in ESCC.

Abstract
INTRODUCTION The prognosis of unresectable advanced esophageal squamous cell carcinoma (ESCC) has gradually improved due to efforts for the development of systemic chemotherapy or concurrent chemoradiotherapy. AREAS COVERED Chemotherapeutic agents such as cytotoxic agents, molecular-targeted agents, and immune checkpoint inhibitors, sometimes used with irradiation, lead in the treatment of unresectable advanced ESCC. Here, we review the latest treatment strategies for unresectable advanced ESCC and discuss future perspectives. EXPERT OPINION Immunotherapeutic agents will be part of the treatment of unresectable advanced ESCC in the near future. However, definitive predictive biomarkers to determine good patient candidates remain unclear for immunotherapy in patients with ESCC. Further research is warranted to identify those biomarkers working individually and in combination. Moreover, genome-based therapeutics enable individualized and patient-specific treatment. The development of molecular-targeted drugs against actionable or druggable genes is in progress.

Abstract
Systemic treatment of advanced esophageal squamous cell carcinoma (ESCC) mainly consists of cytotoxic agents, aiming to palliate symptoms and prolong survival. Cisplatin and 5-fluorouracil have been considered standard treatment for several decades. Efforts to develop more effective treatment have led to clinical trials testing triplet, irinotecan-based, oxaliplatin-based and paclitaxel-based regimens. Molecular-targeting agents, mainly anti-EGFR inhibitors including gefitinib, panitumumab and nimotuzumab, have been investigated; however, no molecular-targeting agents demonstrate the clinical utility in Phase 3 trials so far. Negative results from Phase 3 trials testing gefitinib and panitumumab suggest the importance of identifying predictive biomarkers of responses to molecular-targeting agents. On the basis of results from Phase 3 trials testing PD-1 inhibitors, nivolumab and pembrolizumab, are anticipated to be the standard treatment for patients with ESCC. Dual immune checkpoint inhibition and immunotherapy in combination with cytotoxic agents are under study. Recent advances in next-generation sequencing technologies provide comprehensive catalogues of genetic alterations in ESCC which may lead to therapeutic breakthroughs in a personalized manner. Here, we review the existing clinical data and discuss future perspectives with a focus on the systemic treatment of advanced ESCC.

Abstract
Our previous trial with a docetaxel, cisplatin, and 5-fluorouracil (DCF) regimen showed high response rates in metastatic squamous cell carcinoma of the esophagus (SCCE). The observed increased toxicity of the DCF regimen, however, was clinically harmful. S-1, an oral anticancer drug, has been approved as a combination therapy for SCCE, and alternate-day regimen with S-1 has shown lower levels of toxicity. This prospective single-center phase I/II trial examines the efficacy and toxicity of a combination of docetaxel, cisplatin, and an alternate-day regimen of S-1 (modified DCS) for patients with metastatic SCCE. We use a two-stage design. Phase I is undertaken to determine the maximum tolerated dose and the recommended dose. The phase I trial adopts a three-patient cohort with escalating dose study design. In the phase II trial, the primary endpoint is the assessment of the overall response rate (Response Evaluation Criteria in Solid Tumors 1.1). The secondary endpoints are the evaluation of drug-related toxicity (National Cancer Institute Common Toxicity Criteria 4.0), overall survival, and progression-free survival. Fifty patients with metastatic SCCE participate in the phase II section. This study protocol is the first to test the effects of the modified DCS regimen for metastatic SCCE.

Abstract
Squamous cell carcinoma of the esophagus (SCCE) has a poor prognosis compared with other gastrointestinal cancers. Many patients present with locoregional unresectable or metastatic disease at the time of diagnosis. For these patients with metastatic esophageal cancer, chemotherapy is generally indicated. The aim of this phase I/II study was to evaluate the efficacy and safety of the combined use of docetaxel, cisplatin (CDDP) and 5-fluorouracil (5-FU)(DCF) in patients with recurrent/metastatic SCCE. This study adopted divided doses of docetaxel and CDDP in order to reduce the toxicities of the treatment. The dose of docetaxel was escalated using the following protocol in the phase I stage: level 1, 30 mg/m2; level 2, 35 mg/m2 and level 3, 40 mg/m2, which was intravenously infused for 2 hours on days 1 and 8. CDDP was administered at a dose of 12 mg/m2 infused for 4 hours on days 1-5. The 5-FU was administered at a dose of 600 mg/m2 continuously infused from day 1 to 5. This regimen was repeated every 4 weeks. The study subjects were nine patients (phase I) and 48 patients (phase II). The recommended dose was determined as level 3 in phase I. In the phase II stage, the overall response rate was 62.5%, with a complete response rate of 12.5%. The median progression-free survival was 6 months, and the median overall survival was 13 months. Grade 3/4 toxicities of leukopenia, neutropenia and febrile neutropenia occurred in 64.6%, 68.8% and 14.6% of the patients, while grade 3/4 non-hematological toxicities were relatively rare. No treatment-related death was recorded. This modified DCF regimen with divided doses can be a tolerable and useful regimen of definitive chemotherapy for unresectable SCCE because of its high efficacy, although adequate care for severe neutropenia must be administered.

Abstract
BACKGROUND We performed a prospective, multi-institutional, phase-II, clinical trial of a docetaxel, nedaplatin, and 5-fluorouracil (DNF) regimen in patients with unresectable esophageal cancer. Our goal was to determine the efficacy and feasibility of this DNF protocol. METHODS Thirty-four patients with unresectable esophageal cancer were enrolled and received DNF therapy. The DNF regimen was repeated every 4 weeks for up to 8 weeks, based on the following recommended doses: docetaxel, 60 mg/m(2) (day 1); nedaplatin, 70 mg/m(2) (day 1); and 5-fluorouracil, 700 mg/m(2) (days 1-5). The primary endpoint was the response rate. The secondary endpoints were overall survival and chemotherapy toxicities. RESULTS The complete response rate and response rate were 5.9 and 47.1 %, respectively. The 2-year overall survival rate and progression-free survival rate were 44.3 and 27.3 %, respectively. The median survival time was 594 days. The median progression-free time was 277 days. No treatment-related deaths occurred. Thirty patients (30/34) with grade 3, 4 neutropenia improved relatively quickly with administration of granulocyte colony-stimulating factor. CONCLUSIONS DNF combination chemotherapy is a useful regimen with relatively minor adverse events and may serve as an effective protocol in patients with unresectable esophageal cancer.

Abstract
PURPOSE This phase I/II study was aimed to determine the recommended dose (RD) of docetaxel, cisplatin, and 5-fluorouracil as combination chemoradiotherapy (DCF-RT) for patients with esophageal cancer and to evaluate the efficacy and safety of this protocol. METHODS Fourteen patients with esophageal cancer enrolled in this dose escalation study to determine the RD for a phase III trial. Efficacy and toxicity in DCF-RT of RD were evaluated in 37 patients with esophageal cancer. RESULTS The RD for DCF-RT for esophageal cancer in the present study was 50 mg/m(2) docetaxel plus 60 mg/m(2) cisplatin on day 1 and day 29 plus 600 mg/m(2) 5-FU on days 1-4 and days 29-32 and concurrent radiation of 60 Gy/30 fractions/6 weeks. The main toxicities were myelotoxicity and radiation esophagitis. In this phase I/II study, we could have safety and feasibility by RD, because there was low mortality and most toxicities were manageable level. The complete response (CR) rate and response rate were 54.1 and 83.8 %, respectively, in the phase II study. In patients with a classification of clinical T4, the CR rate and response rate were 47.6 and 85.7 %, respectively. The 2-year overall survival rate, 2-year progression-free survival rate, and median survival time (MST) were 52.9, 50.0 %, and 24.7 months, respectively. In patients with clinical T4 classification, the 2-year overall survival rate, 2-year progression-free survival rate, and MST were 43.5, 44.9 %, and 21.6 months respectively. CONCLUSIONS DCF-RT keeps safety and feasibility by management of myelotoxicity adequately in RD. This protocol might produce a high CR rate and favorable prognosis compared with standard chemoradiotherapy for advanced esophageal cancer.

Abstract
To determine the efficacy of postoperative adjuvant chemotherapy with docetaxel + cisplatin + 5-fluorouracil (DCF) in lymph node metastasis-positive esophageal cancer, we retrospectively analyzed 139 patients with stage II/III (non-T4) esophageal cancer with lymph node metastasis (1-6 nodes), who did not receive preoperative treatment and underwent three-field lymph node dissection in the Juntendo University Hospital between December, 2004 and December, 2009. The tumors were histologically diagnossed as squamous cell carcinoma. The patients were divided into two groups, a surgery alone group (S group, 88 patients) and a group that received postoperative DCF therapy (DCF group, 51 patients). The disease-free and overall survival were compared between the groups and a multivariate analysis of prognostic factors was performed. The same analysis was performed for cases classified as N1 and N2, according to the TNM classification. There were no significant differences between the S and DCF groups regarding clinicopathological factors other than intramural metastasis and main tumor location. The presence of intramural metastasis, blood vessel invasion and the number of lymph nodes were identified as prognostic factors. The 5-year disease-free and overall survival were 55.8 and 57.3%, respectively, in the S group and 52.8 and 63.0%, respectively, in the DCF group. These differences were not considered to be statistically significant (P=0.789 and 0.479 for disease-free and overall survival, respectively). Although there were no significant differences in disease-free and overall survival between the S and DCF groups in N1 cases, both disease-free and overall survival were found to be better in the DCF group (54.2 and 61.4%, respectively) compared to the S group (29.6 and 28.8%, respectively) in N2 cases (P=0.029 and 0.020 for disease-free and overall survival, respectively). Therefore, postoperative adjuvant chemotherapy with DCF was shown to improve disease-free and overall survival in moderate lymph node metastasis-positive cases (N2), suggesting that the DCF regimen may be effective as postoperative adjuvant chemotherapy for patients with lymph node metastasis from esophageal cancer.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (NACRT) for esophageal squamous cell carcinoma (ESCC) is beneficial in the setting of a complete pathological response. Rad51 expression affects both chemo- and radiosensitivity in many cancers; however, its role in ESCC is unclear. METHODS Rad51 expression was investigated by immunohistochemical staining with resected specimens in 89 ESCC patients who underwent surgery without preoperative therapy. The association with Rad51 and clinicopathological factors was assessed. The expression of Rad51 was also investigated in pretreatment biopsy specimens in 39 ESCC patients who underwent surgery after NACRT and compared with the pathological response to NACRT. RESULTS Lymph node metastasis was more frequently observed in Rad51-positive cases than negative cases (58.5 vs. 30.6%, P = 0.0168) in patients treated with surgery alone. Disease-specific survival was decreased in Rad51-positive cases compared to Rad51-negative cases (5 year survival: 79.6 vs. 59.3%, P = 0.0324). In NACRT patients, completed pathological responses were more frequently observed in Rad51-negative cases than in Rad51-positive cases (68.8 vs. 46.5%, P = 0.0171). CONCLUSIONS Rad51 expression in ESCC was associated with lymph node metastasis and poor survival. Additionally, Rad51 expression in pretreatment biopsy specimens was a predictive factor for the response to NACRT.

Abstract
PURPOSE S-1 is widely used for various cancers. It may be useful for esophageal squamous cell carcinoma (ESCC); however, there are insufficient data. The purpose is to provide results of an analysis of S-1 monotherapy for unresectable and recurrent ESCC. PATIENTS AND METHODS Twenty patients with histologically proven ESCC who were previously treated with other chemo(radio)therapies were treated with S-1 alone as second- or third-line chemotherapy. RESULTS A complete response (CR) was observed in 1 case (5%). A partial response (PR), stable disease (SD), and progressive disease (PD) were seen in 4 (20.0%), 7 (35.0%), and 8 (40.0%) cases, respectively. Two cases (10%) of anemia, 1 case (5%) of leukopenia, 3 cases (15%) of fatigue, and 3 cases (15%) of diarrhea were observed as grade 3 toxicity; however, there were no cases of grade 4 toxicity. The 1-year progression-free survival (PFS) rate was 10.0%, and the median PFS was 100 days. The 1-year overall survival (OS) was 30.5%, and the median OS was 330 days. The 1-year PFS rate in CR/PR/SD and PD was 16.7 and 0%, and the median survival time was 120 and 40 days. CONCLUSION S-1 is a promising new drug which can be used as a second- or third-line chemotherapy for ESCC.

Abstract
The treatment results of patients with locally advanced esophageal carcinomas have evolved since the publication of the first trial of concurrent mitomycin C and 5-fluorouracil with radiotherapy (RT) in 1983. Subsequent studies refined and improved on the concurrent chemotherapy (chemo) with administration of cisplatin and 5-fluorouracil infusion (PF). Chemo (PF) before surgery improved overall survival (OS) in those patients in most of the randomized trials and in meta-analyses. Two courses of PF concurrent with irradiation followed by additional two courses of PF were superior to RT alone without surgery for both groups. Concurrent chemoradiotherapy followed by surgery was found to have statistically improved OS as compared with surgery only in randomized trials and meta-analyses. In most of these studies, it was found that those patients with pathologic complete response to the initial treatment(s) did better than those who had no improvement at all. Current treatment outcome for these diseases is disappointing; newer strategies including induction chemo with the optimal combination, proper dosage of each drug, and proper number of courses before concurrent chemoradiotherapy; improvement in RT; and immunotherapy with or without subsequent surgery are exciting and definitely need to be investigated in prospective randomized trial(s).

Abstract
BACKGROUND Although multidrug resistance protein 2 (MRP2) confers chemoresistance in some cancer types, its implication on oesophageal squamous cell carcinoma (ESCC) remains unclear. METHODS We evaluated MRP2 expression by immunohistochemistry and RT-PCR using 81 resected specimens from ESCC patients who did or did not receive neo-adjuvant chemotherapy (NACT), including 5-fluorouracil, doxorubicin, and cisplatin (CDDP). Correlation between MRP2 expression and response to chemotherapy was also examined in 42 pre-therapeutic biopsy samples and eight ESCC cell lines. RESULTS MRP2-positive immunostaining was more frequently observed in ESCCs with NACT than in those without NACT (27.3 vs 5.4%). The MRP2-positive patients showed poorer prognosis than MRP2-negative patients (5-year survival rate, 25.6 vs 55.7%). Concordantly, ESCC with NACT showed 2.1-fold higher mRNA expression of MRP2 than those without NACT (P=0.0350). In pre-therapeutic biopsy samples of patients with NACT, non-responders showed 2.9-fold higher mRNA expression of MRP2 than responders (P=0.0035). Among the panel of ESCC cell lines, TE14 showed the highest MRP2 mRNA expression along with the strongest resistance to CDDP. Inhibition of MRP2 expression by small-interfering RNA reduced chemoresistance to CDDP. CONCLUSION Our data suggested that MRP2 is one of molecules, which regulate the sensitivity to chemotherapy including CDDP in advanced ESCC patients.

Abstract
The incidence of adenocarcinoma of the esophagogastric junction (AEG) is dramatically increasing in Western countries, while it is not increasing in Eastern countries. Siewert type I tumors are observed less frequently in Eastern countries in comparison to Western countries. On the other hand, other clinicopathological features of AEG, including age, male-to-female ratio, pathological grade, tumor progression, and prognosis, are similar in Western and Eastern countries. Two surgical phase III trials have indicated that AEG type I should be treated surgically as esophageal cancer, while types II and III should be regarded as true gastric cancer. No phase III trials have demonstrated a significant interaction comparing hazard ratios for death between AEG and true gastric cancer in the subset analyses with regard to chemotherapy.

Abstract
Perioperative chemotherapy (CT) and chemoradiotherapy are widely used for advanced esophageal cancer. We evaluated the chemosensitivity of patients displaying recurrent esophageal cancer after esophagectomy with perioperative CT. From the database at National Cancer Center Hospital in Tokyo, we extracted recurrent esophageal cancer cases after perioperative CT and evaluated the effectiveness of the first CT against the recurrent disease according to the duration between termination of the original perioperative CT and recurrence with treatment-free intervals (TFIs) <or=6 and >6 months. Systemic CT for their recurrent disease was performed for 30 esophageal cancer patients after perioperative CT. All patients received 5-fluorouracil and cisplatin as perioperative CT, with relapses occurring at TFIs <or=6 months in 11 patients (eight received platinum-containing regimens and three received docetaxel for their recurrent disease) and >6 months in 19 patients (all received platinum-containing regimens). The response rate of patients experiencing a recurrence at TFIs <or=6 and >6 months was 0 and 37% (P = 0.029), the median progression-free survival was 2.8 and 4.8 months (log-rank P = 0.001) and the median overall survival was 6.1 and 10.2 months (log-rank P = 0.012), respectively. Recurrence at the TFI <or=6 months could represent resistance to CT, so regimens may need to be altered depending on a patient's specific TFI.

Abstract
Esophageal cancer (EC) is a highly lethal disease. Approximately 50% of patients present with metastatic EC and most patients with localized EC will have local recurrence or develop metastases, despite potentially curative local therapy. The most common sites of distant recurrence are represented by lung, liver and bone while brain and breast metastases are rare. Usually patients with advanced disease are not treated aggressively and their median survival is six months. We report a woman patient who developed breast and brain metastases after curative surgery. We treated her with a highly aggressive chemotherapeutic and surgical combination resulting in a complete remission of the disease even after 11-year follow-up. We think that in super selected patients with more than one metastasis, when functional status is good and metastases are technically resectable, a surgical excision may be considered as a salvage option and chemotherapy should be delivered to allow a systemic control.

Abstract
PURPOSE To evaluate the correlation between radiation dose and locoregional control (LRC) for patients with Stage II-III unresectable esophageal cancer treated with concurrent chemotherapy and radiotherapy. METHODS AND MATERIALS The medical records of 69 consecutive patients with clinical Stage II or III esophageal cancer treated with definitive chemoradiotherapy at the University of Texas M. D. Anderson Cancer Center between 1990 and 1998 were retrospectively reviewed. Of the 69 patients, 43 had received < or =51 Gy (lower dose group) and 26 >51 Gy (higher dose group). The median dose in the lower and higher dose groups was 30 Gy (range, 30-51 Gy) and 59.4 Gy (range, 54-64.8 Gy), respectively. Two fractionation schedules were used: rapid fractionation, delivering 30 Gy at 3 Gy/fraction within 2 weeks, and standard fractionation, delivering > or =45 Gy at 1.8-2 Gy/fraction daily. Total doses of <50 Gy were usually given with rapid fractionation. Cisplatin and 5-fluorouracil were administrated to 93% of the patients. RESULTS The patient characteristic that differed between the two groups was that patients in the lower dose group were more likely to have had weight loss >5% (46.2% vs. 23.3%). The lower dose group had more N1 tumors, but the tumor classification and stage grouping were similar in the two groups. The median follow-up time for all patients was 22 months (range, 2-56 months). Patients in the higher dose group had a statistically significant better 3-year local control rate (36% vs. 19%, p = 0.011), disease-free survival rate (25% vs. 10%, p = 0.004), and overall survival rate (13% vs. 3%, p = 0.054). A trend toward a better distant-metastasis-free survival rate was noted in the higher dose group (72% vs. 59%, p = 0.12). The complete clinical response rate was significantly greater in the higher dose group (46% vs. 23%, p = 0.048). In both groups, the most common type of first failure was persistence of the primary tumor. Significantly fewer patients in the higher dose group had tumor persistence after treatment (p = 0.02). No statistically significant difference was found between the two groups in the pattern of locoregional or distant failure. The long-term side effects of chemoradiotherapy were similar in the two groups, although it was difficult to assess the side effects accurately in a retrospective fashion. On multivariate analysis, Stage II (vs. III) disease and radiation dose >51 Gy were independent predictors of improved LRC, and locoregional failure was an independent predictor of worse overall survival. CONCLUSION Our data suggested a positive correlation between radiation dose and LRC in the population studied. A higher radiation dose was associated with increased LRC and survival in the dose range studied. The data also suggested that better LRC was associated with a lower rate of distant metastasis. A threshold of tumor response to radiation dose might be present, as suggested by the flattened slope in the high-dose area on the dose-response curve. A carefully designed dose-escalation study is required to confirm this assumption.

Abstract
BACKGROUND We present the results of a prospective phase-II-study of neoadjuvant combined radiochemotherapy followed by surgical resection in patients with histological proven locally advanced squamous cell carcinoma of the esophagus located at or above the level of the tracheal bifurcation. METHODOLOGY Between February 1995 and March 2000 a total of 76 patients with esophageal squamous cell carcinoma (uT3/4N0/+-categories) received simultaneous combined neoadjuvant radiochemotherapy consisting of a continuous intravenous infusion of 5-fluorouracil (300 mg/m2/day) 7 day per week concurrently with conventional fractioned external beam radiation therapy (2 Gy/day), five fractions per week up to a total dose of 30 Gy. RESULTS Radiochemotherapy related acute severe toxicity rate (CTC-grade-III) occurred in 34 patients, two patients died. Sixty-four patients underwent surgery with a complete resection in 48 patients. Three patients died during a 90-day post-operative course. The histopathological workup revealed no viable residual tumour cells in eight patients (ypCR) and according to the modified criteria of Mandard in 26 patients a histopathological response. Twenty-two of these patients underwent a R0-resection. The median follow-up time was 5.4 years with an overall median survival time of 20.6 months. The median survival in the 26 responders was 32.3 months versus 19.5 months in 38 non-responders (p=0.03). CONCLUSIONS Patients with locally advanced squamous cell carcinoma of the esophagus, who respond to preoperative neoadjuvant combined radiochemotherapy, seem to have more benefit from subsequent resection than non-responding patients.

Abstract
PURPOSE To investigate the effect of induction chemotherapy (CHT) before trimodality therapy on the outcome of patients with resectable cancer of the esophagus. METHODS AND MATERIALS This retrospective study included 81 consecutive patients with resectable cancer of the esophagus who received neoadjuvant chemoradiotherapy followed by esophagectomy between January 1990 and December 1998 (inclusive). Thirty-nine patients underwent chemoradiotherapy followed by esophagectomy (CHT/RT+S), 42 received additional induction CHT followed by CHT/RT+S (CHT+CHT/RT+S). Of the 81 patients, 47 were entered in institutional or national prospective trials (6 in the CHT/RT+S and 41 in the CHT+CHT/RT+S group). Induction CHT consisted of three courses of 5-fluorouracil (5-FU), cisplatin, and paclitaxel given in 28-day cycles in 37 patients (88.1%). Concurrent CHT was 5-FU and platinum based. The median radiation dose for patients treated with CHT/RT+S was 30 Gy (range, 30-50.4 Gy) delivered in a median of 10 fractions (range, 10-28 fractions) and 45 Gy (range, 30-45 Gy) in a median of 25 fractions (range, 10-25 fractions) for patients treated with CHT+CHT/RT+S. Esophagectomy was performed 6-8 weeks after completion of concurrent chemoradiotherapy. Most patients underwent transthoracic esophagectomy (n = 66, 82.5%). RESULTS The pretreatment characteristics were well balanced between the two groups except for age. The median follow-up time was 29 months (22 months for the CHT/RT+S group and 38.5 months for the CHT+CHT/RT+S group) for all patients and 49 months for living patients. The actuarial overall survival (OS), disease-free survival (DFS), locoregional control (LRC), and distant metastasis-free survival (DMFS) rate at 5 years for the entire group was 46%, 36.6%, 70.7%, and 53.2%, respectively. Statistically significant differences in the OS, DFS, and LRC rates between the two groups were detected. Specifically, the 5-year OS rate was 22.8% and 71.1% in the CHT/RT+S and CHT+CHT/RT+S group (p = 0.0001), respectively. The 5-year DFS rate was 27.6% and 56.6% in the CHT/RT+S and CHT+CHT/RT+S group (p = 0.003), respectively. The 5-year LRC rate was 64.2% and 85.6% in the CHT/RT+S and CHT+CHT/RT+S group (p = 0.007), respectively. The difference in the DMFS rate between the two groups was statistically significant, with a 2- and 5-year actuarial rate of 63.9% and 51.9%, respectively, in the CHT/RT+S group and 76.9% and 74.1%, respectively, in the CHT+CHT/RT+S group (p = 0.04). The statistically significant differences persisted when patients who received >/=45 Gy in each group were compared. Among those patients, the 5-year OS, DFS, LRC, and DMFS rates were 23.1%, 15.4%, 58.6%, and 39.2%, respectively, for those receiving CHT/RT+S, and 71.4% (p = 0.001), 55.8% (p = 0.0008), 84.6% (p = 0.005), and 77.3% (p = 0.009), respectively, for those receiving CHT+CHT/RT+S. The pathologic complete response (pCR) rate was greater in the CHT+CHT/RT+S group compared with in the CHT/RT+S group (p = 0.008). In univariate analysis, young age, good Karnofsky performance status, Stage II disease, total radiation dose, multiple drug regimen for concurrent CHT, pCR, R0 resection, distant disease progression, and CHT+CHT/RT+S treatment proved to be prognostic factors for OS. Lower esophageal/gastroesophageal junction tumor location, pCR, R0 resection, and CHT+CHT/RT+S treatment were favorable prognostic factors for LRC. Neither the total radiation dose nor multiple drugs for concurrent CHT were negative prognostic factors for LRC. In multivariate analysis, pCR, R0 resection, and treatment with CHT+CHT/RT+S were independent positive predictive factors for OS, and distant recurrences were negative predictive factors for OS. R0 resection, CHT+CHT/RT+S treatment, and lower esophageal/gastroesophageal junction tumor location were positive predictive factors for LRC. The radiation dose was not identified as an independent prognostic factor for either OS or LRC in the multivariate analysis. Meaningful multivariate analysis could not be performed when the multiple drug vperformed when the multiple drug variable was included in the model because of the small number of patients. CONCLUSION Significantly greater LRC, DFS, OS, and DMFS were found in patients treated with CHT+CHT/RT+S compared with those treated with CHT/RT+S. The pCR rate was significantly higher in the CHT+CHT/RT+S group. Induction CHT was an independent favorable prognostic factor for both LRC and OS for the population included in this study. Our data suggest that a randomized trial comparing CHT+CHT/RT+S and CHT/RT+S is warranted to assess further the merits of this treatment in patients with this currently very lethal cancer.

Abstract
The overall success rate nationally in treating esophageal carcinomas remains poor, with over 90% of patients succumbing to the disease. In part I of this two-part series, we explored epidemiology, presentation and progression, work-up, and surgical approaches. In part II, we explore the promising suggestions of integrating chemotherapy and radiation therapy into the multimodal management of esophageal cancers. Alternative approaches to resection alone have been sought because of the overall poor survival rates of esophageal cancer patients, with failures occurring both local-regionally and distantly. Concomitant chemotherapy and radiation therapy (XRT) have been shown, by randomized trial, to be more effective than XRT alone in treating unresectable esophageal cancers and also have shown promise as a neoadjuvant treatment when combined with surgery in the multimodal treatment of this disease. Various studies have also addressed issues such as preoperative chemotherapy, radiation dose escalation, chemotherapy/XRT as a definitive treatment versus use as a surgical adjuvant, and alternative chemotherapy regimens. There are suggestions of some progress, but this remains a difficult problem area in which management is continuing to evolve.

Abstract
BACKGROUND We undertook a multicentre phase II trial to evaluate the safety and efficacy of primary chemotherapy followed by chemoradiation for localised adenocarcinoma or squamous carcinoma of the oesophagus. PATIENTS AND METHODS Chemotherapy comprised five 3-weekly cycles of cisplatin and protracted continuous infusion 5-fluorouracil, with conformally planned radiotherapy commencing at the start of the fifth cycle. RESULTS The planned treatment programme was completed by 39 of 72 patients (54%), and a further 13% completed chemotherapy and proceeded to surgical oesophagectomy. Response rates to chemotherapy and to the entire treatment programme were 47% [95% confidence interval (CI) 34% to 60%] and 56% (CI 43% to 68%). The dysphagia score improved in 54% of patients. The median survival duration was 14.6 months with 1- and 2-year survival rates of 58.7% and 44.1%, respectively. Grade III/IV chemotherapy-related toxicity occurred in 38% of patients, and there were no treatment-related deaths. CONCLUSIONS This is a feasible and active treatment regimen providing palliative benefits for patients with poor-prognosis localised oesophageal cancer.

Abstract
The objective of this study was to determine the toxicities and maximum tolerated dose (MTD) of a dose-dense schedule with a fixed dose of cisplatin and escalating doses of paclitaxel in patients with metastatic or irresectable squamous cell-, adeno-, or undifferentiated carcinoma of the oesophagus. Patients received paclitaxel over 3 h followed by a 3-h infusion of a fixed dose of cisplatin of 70 mg/m(2) on days 1, 8, 15, 29, 36 and 43. The starting dose of paclitaxel was 80 mg/m(2). Patients were re-treated if white blood cell count (WBC) was >/=1 x 10(9) cells/l, except for day 29 when the WBC had to be >/=3 x 10(9) cells/l. Six patients were treated at each dose level. The dose of paclitaxel was increased by 10 mg/m(2) per level. Of the 24 patients enrolled, 13 had adenocarcinoma, 10 had squamous cell carcinoma and one had an undifferentiated carcinoma. All patients were evaluable for toxicity and 22 of 24 patients were evaluable for response. The paclitaxel dose could be escalated to 110 mg/m(2). At this dose, 3 out of 6 patients developed dose-limiting toxicity (DLT) including neutropenic enterocolitis with sepsis, vomiting and diarrhoea. Diarrhoea grades 3 and 4 was seen in 4 (17%) patients. Two of these patients died of neutropenic enterocolitis. Neutropenia grades 3 or 4 was seen in 20 (83%) patients, but apart from the two patients with neutropenic enterocolitis no other infectious complications were seen. Mild to moderate sensory neurotoxicity was seen in 11 (46%) patients (grade 1 in 8 patients and grade 2 in 3 patients). Other toxicities were mild and easily manageable. Of the 22 evaluable patients, 11 (50%) patients achieved a partial or complete response with a median duration of 13 months. Ten patients with either locally advanced disease or supraclavicular or celiac lymph nodes received additional local treatment after response to chemotherapy, seven patients are still without evidence of disease after a median follow-up of 32 months. Paclitaxel at a dose 100 mg/m(2) infused over 3 h followed by a 3-h infusion of 70 mg/m(2) cisplatin can be recommended for further studies in patients with metastatic or unresectable oesophageal cancer. Occurring diarrhoea should be handled with caution because it may be a sign of neutropenic enterocolitis. The response rate of this dose-dense schedule seems encouraging.

Abstract
The aim of this study was to determine the toxicity, response rate, failure-free survival, and overall survival in a treatment program comprising continuous infusion carboplatin, short in-fusion 5-fluorouracil (5-FU) and radiotherapy for localized carcinoma of the thoracic esophagus. To be eligible, patients were required to have Karnofsky performance status greater than or equal to 60, adequate organ function, and have received no prior therapy. Planned radiation dose was 50 Gy in 25 fractions over 5 weeks. 5-FU was to be administered commencing days 1 and 29 of radiotherapy, and given at a dose of 1 g/m2/d for 4 days as a continuous infusion. Carboplatin was to commence on day 1 of radiotherapy and be given throughout the period of radiation as a continuous infusion. The starting dose of carboplatin was 28 mg/m2/d. The protocol specified a 25% dose reduction of carboplatin if more than two of the first six patients experienced dose-limiting toxicity (DLT). DLT was defined as grade IV neutropenia lasting more than 7 days, grade IV thrombocytopenia, or any grade IV nonhematologic toxicity. All 23 patients in the study received protocol radio-therapy, except one who was given an extra 10 Gy. Seven patients received carboplatin at 28 mg/m2/d and 16 received 21 mg/m2/d. Hematologic DLTs were experienced by all of the seven patients receiving the higher dose. No patients in the low-dose group experienced hematologic DLTs, and only 2 of 16 ceased chemotherapy early because of myelosuppression. Three patients in the low-dose group experienced grade IV esophagitis but were able to complete protocol radiotherapy. Apart from esophagitis, nonhematologic toxicity was generally moderate or mild. Six patients had thrombosis complicating the central venous catheters. Endoscopy was performed in 21 patients (91%), with an overall complete response rate of 65% (CI: 43-84%) for the whole group or 71% (CI: 48-89%) for the endoscopically evaluated group. Estimated median failure-free survival time was 8.9 months (CI: 7.1-12.9), and estimated median overall survival time was 21.4 months (CI: 9.6 -35.4). Carboplatin at 21 mg/m2/d as a continuous infusion may be given safely in combination with short infusional 5-FU and radiotherapy for localized carcinoma of the esophagus. This combination has resulted in response data comparable to that of larger studies of cisplatin-containing regimens and warrants further study, ideally in a phase III randomized controlled trial.

Abstract
OBJECTIVE To evaluate the use of positron emission tomography using [(18)F]-fluorodeoxyglucose (FDG-PET) to assess the response to neoadjuvant radiotherapy and chemotherapy in patients with locally advanced esophageal cancer. SUMMARY BACKGROUND DATA Imaging modalities, including endoscopy, endoscopic ultrasound, computed tomography, and magnetic resonance imaging, currently used to evaluate response to neoadjuvant treatment in esophageal cancer do not reliably differentiate between responders and nonresponders. METHODS Twenty-seven patients with histopathologically proven squamous cell carcinoma of the esophagus, located at or above the tracheal bifurcation, underwent neoadjuvant therapy consisting of external-beam radiotherapy and 5-fluorouracil as a continuous infusion. FDG-PET was performed before and 3 weeks after the end of radiotherapy and chemotherapy (before surgery). Quantitative measurements of tumor FDG uptake were correlated with histopathologic response and patient survival. RESULTS After neoadjuvant therapy, 24 patients underwent surgery. Histopathologic evaluation revealed less than 10% viable tumor cells in 13 patients (responders) and more than 10% viable tumor cells in 11 patients (nonresponders). In responders, FDG uptake decreased by 72% +/- 11%; in nonresponders, it decreased by only 42% +/- 22%. At a threshold of 52% decrease of FDG uptake compared with baseline, sensitivity to detect response was 100%, with a corresponding specificity of 55%. The positive and negative predictive values were 72% and 100%. Nonresponders to PET scanning had a significantly worse survival after resection than responders. CONCLUSION FDG-PET is a valuable tool for the noninvasive assessment of histopathologic tumor response after neoadjuvant radiotherapy and chemotherapy.

Abstract
BACKGROUND AND OBJECTIVES The prognosis for patients with intramural metastasis (IMM) of esophageal cancer is poor. We examined the role of preoperative chemotherapy in the management of patients with this disease. METHODS Fifteen patients with IMM of esophageal carcinoma received preoperative chemotherapy cisplatin on day 1 and 5-fluorouracil on days 1 to 5. This regimen was repeated after a 3-week interval, except in patients with progressive disease or severe toxicity who received only one cycle of chemotherapy. Patients underwent surgery around 3 weeks after completion of chemotherapy. Clinical response was evaluated and survival was compared with that of patients who did not receive preoperative chemotherapy. RESULTS Toxicity was manageable except in one patient who experienced severe neurological adverse effect. The clinical response rate of the IMM was 66.7% (10/15) and the complete response rate was 6.7% (1/15); for the primary lesion, response rates were 86. 7% and 6.7%, respectively. All 15 patients underwent surgery. Seven of the 15 patients (46.7%) experienced non-fatal operative complications. The 5-year survival rate after surgery was 20%. CONCLUSIONS Preoperative chemotherapy with cisplatin and 5-fluorouracil is feasible in patients with IMM of esophageal carcinoma. This regimen, however, does not improve survival and more effective treatment strategies are required.

Abstract
The results of surgical treatment for advanced esophageal cancer remain extremely poor. Irradiation and chemotherapy are not superior to surgery. Perioperative morbidity and the influence on long-term survival of a combination of surgery and preoperative chemotherapy were investigated in patients with advanced esophageal cancer. Forty-nine patients with advanced esophageal squamous cell carcinoma were subjected to preoperative chemotherapy of cisplatin-5-fluorouracil. Fifty-seven patients were chosen as a historical control group who had not undergone chemotherapy before surgery but had the same histological stages as the chemotherapy group. The response to chemotherapy was assessed by histological studies of surgical specimens. The survival rates noted no significant difference between preoperative chemotherapy plus surgery and a resection alone. However, subclassification according to the grading of chemotherapeutic effectiveness showed that, compared with control, preoperative chemotherapy was beneficial to high responders (P = 0.01), ineffective in low responders (P = 0.61), and detrimental to nonresponders (P = 0.03). Postoperative morbidity was significantly higher in the chemotherapy group than in the control group (P = 0.02). These findings suggest that preoperative chemotherapy is necessary only for high responders and we therefore need to reliably identify non-, low, and high responders before chemotherapy to improve the survival and quality of life of patients with advanced esophageal cancer.

Abstract
A phase II study was conducted to determine the clinical efficacy and toxicity of 5-fluorouracil (5-FU) and low-dose cisplatin (CDDP) in patients with squamous cell carcinoma of the esophagus. Chemotherapy consisted of 5-FU at a dose of 330 mg/m2 per day, given as a 24-h infusion on days 1-7, and CDDP at a dose of 6 mg/m2 per day, given as a 2-h infusion on days 1-5. Either two or four cycles of chemotherapy were administered to 20 patients with stage III advanced esophageal carcinoma. All 20 patients were then assessed for response and toxicity. An objective response was demonstrated by 11 of the 20 patients, with one complete response (CR) and ten partial responses (PR), bringing the response rate to 55%, with a 95% confidence interval of 27% to 83%. Surgical resection of the tumor was performed in all 20 patients. One patient was found to have a grade 3 histological CR. The median survival of all the patients was 20.5 months, with a range of 4.5 to 48.0 months. Neutropenia and thrombocytopenia developed in five (25%) and two (10%) patients, respectively, and the nonhematologic toxicities were insignificant. The findings of this phase II study indicate that preoperative treatment using 5-FU and low-dose CDDP chemotherapy for patients with advanced esophageal carcinoma appears to achieve a high response rate after short-term administration without affecting the quality of sophisticated lymph node dissection.

Abstract
Single-agent therapy with paclitaxel is effective against both squamous cell carcinoma and adenocarcinoma of the oesophagus. However, only limited data are available on the combination of paclitaxel with other cytotoxic drugs in this entity. Patients with unresectable stage III, recurrent or metastatic tumours were treated in a multicentre setting with paclitaxel 90 mg m(-2) given over 3 h intravenously, followed by cisplatin 50 mg m(-2). The courses were repeated every 14 days. Twenty patients with squamous cell carcinoma or adenocarcinoma of the oesophagus were evaluable for response. The overall remission rate was 40% (8/20), including 15% (3/20) clinically complete responses. Clinical benefit response, defined as relief of dysphagia and/or significant gain in weight, was achieved in 70% of the patients. Neutropenia of CTC grade 3 occurred only in 10% of the patients; no grade 4 neutropenia and no severe thrombocytopenia was encountered. CTC grade 4 neurotoxicity was seen in 5% of patients. Cisplatin/paclitaxel administered every 14 days, was effective in patients with poor prognosis oesophageal cancer and toxicity was acceptable.

Abstract
PURPOSE To define the activity and toxicity of preoperative chemotherapy and postoperative concomitant chemoradiotherapy in patients with carcinoma of the esophagus, and to determine the effect on survival in patients treated with this approach. PATIENTS AND METHODS Patients were treated with two 21-day cycles of induction chemotherapy with cisplatin 100 mg/m2 on day 1, 5-fluorouracil (5-FU) 800 mg/m2/day continuous infusion on days 1-5, and leucovorin 100 mg/m2 every four hours on days 1-5. Surgical resection was performed if feasible (and could also be performed prior to chemotherapy). Patients then received radiotherapy (50 to 60 Gy) every other week x five to six weeks, concomitantly with 5-FU 800 mg/m2 continuous infusion daily and hydroxyurea 1 g twice daily x five days. RESULTS Forty-six patients were treated. With a minimum follow-up of 58 months, the median survival for the entire group was 16 months; the median survivals for patients with squamous carcinoma and adenocarcinoma were 29 months and 12 months, respectively. Toxicities of induction chemotherapy were severe neutropenia and mucositis; there was one toxic death. Toxicities of concomitant chemoradiotherapy were neutropenia, mucositis and esophagitis. There were five cases of radiation pneumonitis, one fatal. CONCLUSION Induction chemotherapy and postoperative concomitant chemoradiotherapy can be added to surgical resection for carcinoma of the esophagus. Combined modality therapy, as reported here, produces long-term survival benefit, particularly in patients with squamous carcinoma. However, similar outcome results have been reported with less toxic and shorter treatment regimens as tested in randomized studies.

Abstract
A 60-year old male patient who had locally advanced esophageal carcinoma with bulky upper abdominal lymphadenopathy underwent neoadjuvant chemotherapy consisting of 5-fluorouracil (5-FU) and cisplatin (CDDP), followed by concurrent radiotherapy and chemotherapy using protracted low-dose continuous infusion of 5-FU and CDDP. The treatment brought about complete remission in the primary lesion and good partial remission in the upper abdominal lymphadenopathy. He subsequently underwent trans-hiatal esophagectomy after one cycle of adjuvant chemotherapy because local recurrence was suspected. Histopathologic study of the resected specimen demonstrated no malignant tissue in the primary lesion and the lymph nodes. The patient is still alive and disease-free at 26+ months. This result suggests that neoadjuvant chemotherapy followed by concomitant chemotherapy and radiotherapy for patients who have locally advanced squamous cell carcinoma of the esophagus with intensive abdominal lymphadenopathy may offer some chance for sterilization of local and regional metastases and longer survival.

Abstract
OBJECTIVE The objective of this prospective, nonrandomized study was to evaluate the immediate and long-term results of first-line chemotherapy and possible surgery in locally advanced, presumably T4 squamous cell esophageal cancer. SUMMARY BACKGROUND DATA Locally advanced esophageal cancer is rarely operable and has a dismal prognosis. For this reason, neoadjuvant cytoreductive treatments are more and more frequently used with the aim of downstaging the tumor, increasing the resection rate, and possibly improving survival. METHODS From January 1983 to December 1991, 163 consecutive patients with a presumedly T4 squamous cell carcinoma of the thoracic esophagus (group A) received on average 2.5 cycles (range, 1-6) of first-line chemotherapy with cisplatin (100 mg/m2 on day 1) and 5-fluorouracil (1000 mg/m2 per day, in continuous infusion from day 1 through day 5). Chemotherapy was followed by surgery when adequate downstaging of the tumor was obtained. RESULTS Chemotherapy toxicity was WHO grade 0 to 2 in 80% of cases, but 3 toxic deaths (1.9%) occurred. Restaging suggested a downstaging of the tumor in 101 of 163 patients (62%), but only 85 patients (52%) underwent resection surgery; it was complete or R0 in 52 (32%) and incomplete or R1-2 in 33. Overall postoperative mortality was 11.7% (10 of 85), morbidity 41% (35 of 85). Complete pathologic response was documented in 6 patients, and significant downstaging to pStage I, IIA, or IIB occurred in 25 more patients. The overall 5-year survival was 11 % (median, 11 months). After resection surgery, the 5-year survival was 20% (median, 16 months); none of the nonresponders survived 4 years after palliative treatments without resection (median survival, 5 months). The 5-year survival rate of the 52 patients undergoing an R0 resection was 29% (median, 23 months). Stratifying patients according to the R, pT, pN, and pStage classifications, the survival curves were comparable to the corresponding data obtained in the 587 group B patients with "potentially resectable" esophageal cancer who underwent surgery alone during the same period. Furthermore, the results were improved in comparison with 136 previous or subsequent patients with a locally advanced tumor who did not undergo neoadjuvant treatments (group C). In these patients, the R0 resection rate was 7%, and the overall 5-year survival was 3% (median, 5 months). CONCLUSION Although nonrandomized, these results suggest that in locally advanced esophageal carcinoma, first-line chemotherapy increases the resection rate and improves the overall long-term survival. In responding patients who undergo R0 resection surgery, the prognosis depends on the final pathologic stage and not on the initial pretreatment stage.

Abstract
OBJECTIVE To determine whether postoperative adjuvant chemotherapy confers a survival benefit on patients with esophageal squamous cell carcinoma undergoing radical surgery, we undertook a cooperative, prospective randomized controlled trial. METHODS A total of 205 patients underwent transthoracic esophagectomy with lymphadenectomy at eleven institutions between December 1988 and July 1991. These patients were prospectively randomized into two groups (100 patients underwent surgery alone and 105 patients had additional two courses of combination chemotherapy with cisplatin (70 mg/m2) and vindesine (3 mg/m2). The two groups did not differ with respect to sex, age, location of tumor, and distributions of pT, pN, pM, or p stage. RESULTS The 5-year survival was 44.9% in the surgery alone group and 48.1% in the surgery plus chemotherapy group. The relative risk was estimated to be 0.89 (95% confidence interval, 0.61 to 1.31) in the surgery plus chemotherapy group compared with the surgery alone group. No significant differences in survival were detected between the two groups, even with lymph node stratification. CONCLUSION Postoperative adjuvant chemotherapy with cisplatin and vindesine has no additive effect on survival in patients with esophageal cancer compared with surgery alone.

Abstract
Forty-four patients with advanced esophageal squamous cell carcinoma were treated with biochemical modulated combination chemotherapy and surgery. Treatment consisted of cisplatinum (70 mg/m2/day 1, day 22), 5-fluorouracil (5-FU; 700 mg/m2/day, days 1-5, 22-26), and leucovorin (20 mg/m2/day, days 1-5, 22-26) with nutritional support, and surgery (days 42-70, mean day 56). Surgery consisted of subtotal esophagectomy with extended lymphadenectomy. Postoperative adjuvant chemotherapy or additional irradiation to the mediastinum was restricted to patient with residual tumors. Clinical response rate was 63.6% in primary tumor, 52.6% in intramural metastasis, 100% in intraepithelial spread, and 30.9% for metastatic lymph nodes. There was a slight disagreement between the result of evaluation of histological and clinical effect. The incidence of postoperative complications was 25%, and the mortality rate was 2.3%. Overall 1-, 2-, 3-, and 4-year survival rates of the patients were 57%, 37.9%, 28.5%, and 28.5%, respectively. The median survival time was 14.7 months. Responders survived longer than nonresponders. The histological responders survived longer than clinical responders. The 4-year survival rate of patients without residual tumor after treatment was 75% in the superficial cases, 51% in the locoregional cases, and 50% in the widespread cases.

Abstract
Surgery is a crucial part of therapy of oesophageal cancer. The many trials which are described focus on variations in surgical technique. A trend is found that results are better with more extensive procedures. Local control evidently is improved, but an effect on survival is not yet sufficiently shown. Combinations of neoadjuvant radiotherapy and/or chemotherapy with surgery are effective by downstaging offering seemingly better survival in responding patients. Interpretation of trial data, however, is difficult because of the relatively small numbers in individual studies; the differences of the used treatment modalities make an overview approach less reasonable. Great attention should be given in the future trial work to better standardization (interpretation of definitions). Directives for optimal staging should be described in all study protocols.

Abstract
In view of the poor survival after surgery alone for oesophageal cancer, combination with chemotherapy seems rational. A concept of upfront chemotherapy is discussed and seems especially useful for these tumours. The published randomized trials, studying the effect of neoadjuvant chemotherapy do, however, not (yet) show an improved overall survival, apart from one study with a significant median survival benefit at an interim evaluation. The responding patients have in all trials a far better survival than the non-responders. The numbers of patients are small and results of other ongoing and future trials should be awaited. New trials testing high-dose chemotherapy with bone marrow support should be initiated.

Abstract
The purpose of this study was to examine the feasibility of administering all chemotherapy pre-operatively to patients with resectable adenocarcinoma of the oesophagus or gastrooesophageal junction. 32 patients with potentially resectable adenocarcinoma of the oesophagus or gastrooesophageal junction were studied in a stepwise fashion in which combination chemotherapy with cisplatin, high-dose arabinoside and 5-fluorouracil was administered. In the first part, 15 patients were to receive three chemotherapy courses pre-operatively and two chemotherapy courses postoperatively. In the second part, the next 15 patients were to receive all five chemotherapy courses pre-operatively, provided there was an objective response after three courses. Endoscopic ultrasonography was also performed, when feasible, prior to chemotherapy and surgery, and in some patients sequentially between chemotherapy courses. All of the 14 assessable patients in the first group tolerated all three courses of pre-operative chemotherapy, and 86% of patients in this group completed all protocol chemotherapy. In the second group, 9 of 18 (50%) assessable patients tolerated all five courses of preoperative chemotherapy, and 100% of patients in this group received all protocol chemotherapy. The median number of chemotherapy courses for the entire group (32 patients) was five (range one to five). Forty-one per cent (13/32) of patients had a major response to chemotherapy. Sixty-nine per cent (or 76% of 29 patients taken to surgery) had a curative resection. One patient had a pathological complete response. The median survival time of 32 patients was 17 months (range 2-36+ months). 14 patients (37%) remain alive at a median follow-up time of 26+ months. There was a correlation between endoscopic ultrasonographic tumour and nodal stage and pathological tumour and nodal stages in 16 patients. The tumour stage correlation was higher (75%) than the nodal stage correlation (62%). Our data suggest that it is feasible to administer five courses of cisplatin-based chemotherapy to patients with potentially resectable adenocarcinoma of the oesophagus or gastrooesophageal junction. More effective chemotherapy regimens that might result in higher pathological complete response rates and acceptable toxic effects are needed.

Abstract
BACKGROUND Chemoradiotherapy has demonstrated efficacy in esophageal cancer but rarely is curative. To improve local control and decrease metastases, a 7-month regimen was used with standard-dose radiotherapy (RT), cisplatin (DDP), and continuous infusion (CI) 5-fluorouracil (5-FU) in patients with locoregional squamous/adenocarcinoma of the esophagus. METHODS Initial treatment consisted of RT to the esophagus (4000-5000 cGy) for 5-6 weeks, CI 5-FU (300 mg/m2/day) concurrent with RT, and DDP (25 mg/m2/day x 3) for Days 1-3 and 21-23. Two monthly cycles of DDP (75 mg/m2 Day 1) and 5-FU (300 mg/m2 x 21 days) followed. Patients were restaged with endoscopy and computed tomography scan. Patients without evidence of residual disease received three more cycles of chemotherapy (CT); those with persistent tumor underwent esophagectomy or additional CT/RT, and those with disease progression were offered alternative CT. RESULTS From December 1987 to September 1991, 18 men and 8 women, including 2 with adenocarcinoma, were eligible for inclusion in the study. All were evaluable for toxicity and response. The median age was 61.5 years (range, 50-80 years), the median pretreatment weight loss was 9 lbs, and the median serum albumin level was 4.3 mg%. Therapy was toxic; 19 patients were hospitalized for treatment-related esophagitis, thrombosis, or infection. Grade III and IV leucopenia were seen in 12 patients and 1 patient, respectively. One patient had Grade IV thrombocytopenia. Of 26 patients, 17 (65%) had no tumor on restaging. Five patients had recurrences in the esophagus (1), liver (3), and lung (2). Three patients had second neoplasms. The median survival was 24 months. CONCLUSION This treatment regimen provides high frequency of local tumor resolution, but with significant toxicity.

Abstract
Esophageal cancer patients treated with radiotherapy (RTx) are most often those with malignancies too extensive for surgery or those who deemed medically unsuitable for an aggressive surgical approach. Summarizing RTx series, the 2-year survival rate is in the range of 10% and at 5 years about 5%. Although not randomly compared, these results are not significantly worse than those achieved with surgery in more advanced tumors. In stage I/II tumors, more recent trials reported of 5-year survival rates varying between 12% and 20%. These data indicate that irradiation may be administered with curative intention but usually only for patients who are also candidates for primary surgery. On the other hand, modern RTx (doses > 60 Gy) +/- endoluminal after-loading may provide good palliation (relief of dysphagia) for patients with good prognostic factors such as weight loss of less than 10% body weight, good performance status, younger age, and location of the tumor. In the perioperative setting, RTx reduced the frequency of the local recurrences but did not increase the overall resection and R0 resection rates and did not improve survival due to more patients relapsing at distant sites. Combined chemoradiotherapy has shown to be superior to RTx alone with respect to local control, disease free survival and overall survival and in a marked reduction of distant failures. These data support the use of chemoradiotherapy as standard treatment of locally advanced and nonresectable esophageal cancer. They also provide a basis for randomized trials comparing chemoradiotherapy alone versus preoperative treatment modalities.

Abstract
A number of studies have demonstrated that preoperative chemotherapy (CTx) and combination radiochemotherapy (RTx/CTx) in patients with potentially resectable and locally advanced squamous cell esophageal carcinoma is feasible. In patients with potentially resectable tumors, neoadjuvant therapy followed by surgical resection has, however, so far not shown an increase in the resection rate, rate of complete macroscopic and microscopic tumor resections, i.e. R0-resections according to the UICC, or survival time as compared to patients who had surgical resection alone. In this situation a survival benefit, if at all, can be expected only in those who respond to preoperative therapy. At the present time preoperative CTx or RTx/CTx in patients with potentially resectable esophageal carcinoma must therefore be considered investigational and should not be performed outside the context of clinical trials. In patients with locally advanced esophageal carcinoma, neoadjuvant therapy markedly increases the rate of R0-resections and appears to prolong survival. Combined modality therapy in this context is, however, associated with a substantial perioperative mortality and morbidity. Open questions that have to be addressed by randomized studies include the role, extent and timing of surgical resection in the combined modality approach to patients with locally advanced squamous cell esophageal carcinoma. Research has to focus on preoperative staging modalities and the development of more effective and less toxic preoperative therapy regimen to improve identification of patients that might benefit from combined modality therapy and to more effectively combat systemic recurrences.
