OBJECTIVETo investigate the prognostic significance of the preoperative neutrophil-to-lymphocyte ratio (NLR) in patients with esophageal squamous cell carcinoma (ESCC) who received radical resection.

METHODSA retrospective review was performed on 475 patients who underwent radical resection for ESCC in our hospital between January 2007 and December 2008, all patients were diagnosed with ESCC by pathological examination. None accepted neoadjuvant therapy.

RESULTSThe median value of NLR was 1.77 (range, 0.53-11). Based on this cut-off value of 2.5, all the patients were divided into 2 groups: a low NLR (<2.5, n = 389) group and a high NLR ( ≥ 2.5, n = 86) group. The 5-year overall survival rate was 48.6% in patients of the low NLR group and 36.0% in those of the high NLR group (P = 0.009). The ratio of women was higher in the low NLR group (P = 0.04). Univariate analysis showed NLR, age, history of smoking, T stage, N stage, and postoperative adjuvant therapy were associated with survival (P < 0.05 for all). We also found that NLR could be used to divide patients with or without lymph node metastasis into a high and low risk groups. Multivariate analysis revealed that NLR, age, N stage, and postoperative adjuvant therapy were independent risk factors of prognosis.

CONCLUSIONOur results show that preoperative NLR ≥ 2.5 may be a convenient biomarker to predict patients with a poor prognosis after radical resection for ESCC.

OBJECTIVETo retrospectively compare the efficacy of postoperative radiotherapy (RT) alone with that of postoperative radiotherapy with concurrent chemotherapy (CRT) for thoracic esophageal squamous cell carcinoma (EPC) with positive lymph nodes, and to evaluate the clinical value of RT + CRT.

METHODS304 EPC patients underwent esophagectomy with three-field lymph node dissection had pathological lymph node metastases, but no hematogenous distant metastasis. Among them, 140 cases underwent postoperative RT alone, and 164 cases underwent postoperative CRT. The dose of irradiation was 50 Gy, and the chemotherapy regimen was taxol and cis-platinum, and a cycle was 21 days.

RESULTSThe 1-, 3- and 5-year total survival rates of the whole group were 90.1%, 56.6% and 43.3%, respectively, with a median survival time of 49.7 months. The 5-year overall survival rates of the CRT and RT groups were 47.4% and 38.6%, respectively (P = 0.030), with a median survival time of 53.5 and 41.7 months, respectively (P = 0.030). The overall survival rates of the patients who underwent 1, 2, 3, 4 cycles of chemotherapy were 24.4%, 53.0%, 58.1% and 43.3%, respectively (P = 0.007). Among them, the 5-year total survival rate of patients with 2-4 cycles of chemotherapy was significantly better than that of patients who underwent one cycle of chemotherapy (P = 0.001). Univariate analysis showed that number of metastatic lymph nodes, pT stage, therapeutic regimen and number of chemotherapy cycles were significantly correlated with the prognosis of the patients (P < 0.05 for all). Multivariate analysis showed that number of metastatic lymph nodes, pT stage, and number of chemotherapy cycles were independent prognostic factors of the patients (P < 0.05 for all). Early toxic effects including neutropenia, radiation esophagitis, and gastrointestinal effects were significantly more severe in the CRT group than that in the RT group (P < 0.05), however, there were no significant differences of late toxic effects between the two groups (P > 0.05).

CONCLUSIONPostoperative CRT for thoracic EPC with positive lymph nodes can improve the survival rate, with tolerable adverse effects.

Biomarker identification is crucial for the selection of patients who might benefit from radiotherapy. To explore potential markers for response and prognosis in patients with locally advanced esophageal carcinoma treated with radiotherapy followed by surgery, we evaluated the expression of cell cycle checkpoint-related proteins Chk2, Cdc25C, and Cyclin D1. A total of 56 patients with locally advanced esophageal squamous cell carcinoma were treated with radiotherapy followed by surgery. Pretreatment tumor biopsy specimens were analyzed for Chk2, Cdc25C, and Cyclin D1 expression by immunohistochemistry. High expression of Chk2, Cyclin D1, and Cdc25C was observed in 44 (78.6%), 15 (26.8%), and 27 (48.2%) patients, respectively. The median survival was 16 months (range, 3-154 months), with a 5-year overall survival rate of 19.6%. Overexpression of Chk2 was associated with smoking (P = 0.021), overexpression of Cdc25C was associated with patient age (P = 0.033) and tumor length (P = 0.001), and overexpression of Cdc25C was associated with pathologic complete response (P = 0.038). Univariate analysis demonstrated that overexpression of Cdc25C and pathologic complete response was associated with better survival. In multivariate analysis, Cdc25C was the most significant independent predictor of better survival (P = 0.014) for patients treated with radiotherapy followed by surgery. Overexpression of Cdc25C was significantly associated with pathologic complete response and better survival of patients with locally advanced esophageal cancer treated with radiotherapy followed by surgery. These results suggest that Cdc25C may be a biomarker of treatment response and good prognosis for esophageal carcinoma patients. Thus, immunohistochemical staining of Cdc25C in a pretreatment specimen may be a useful method of identifying optimal treatment for patients with esophageal carcinoma.

Most patients with esophageal cancer have advanced disease at presentation. The efficacy of surgical resection alone is often unsatisfactory in patients with stage III or more advanced cancer according to the seventh edition of UICC staging system for esophageal cancer. The systematic multidisciplinary treatment is important. Mounting evidence indicates that preoperative concurrent chemoradiotherapy is the most effective induction therapy to down-stage tumor and increase radical resection rate. For the esophageal squamous cell carcinoma patients with multi-stations and multi-fields lymph node metastasis, preoperative induction chemotherapy would be a viable option. For locally advanced cancers which have been surgically resected, postoperative adjuvant radiotherapy maybe helpful to improve local control for the insufficient surgical dissection. The role of adjuvant chemotherapy also needs further studies. Thoracic esophageal squamous cell carcinoma and lower esophageal adenocarcinoma which is common in western countries are different. We need more prospective clinical studies to establish our treatment modalities for esophageal cancer.

Esophageal squamous cell carcinoma (ESCC) is one of the commonest malignancies in China. Surgery is the main treatment for ESCC. However, the long-term survival is very poor by surgery alone. Perioperative multimodality treatment, including locally and systemically administrated, preoperatively and postoperatively, has been and will be the standard treatment in terms of improving long-term survival. Base on decades of practice and clinical trials, it is believed that preoperative treatment is better than postoperative treatment, and that chemotherapy plus radiotherapy preoperatively is better than either chemotherapy or radiotherapy alone. Therefore, preoperative radiochemotherapy followed by surgery is the standard treatment and future direction for locally advanced ESCC.

The prognosis of patients with locally advanced esophageal cancer treated by surgery alone is poor. The neoadjuvant chemoradiotherapy is considered to improve the long-term survival of patients with locally advanced esophageal cancer. The combination of neoadjuvant chemoradiotherapy and surgery has been recommended to be the standard treatment for the locally advanced esophageal cancer in China even in Europe and America countries. However, available evidence suggests that only those who had histopathologic response seemed to benefit the most from neoadjuvant chemotherapy while non-responders even had rather worse outcome compared to patients with surgery alone. Therefore, predictive markers of response to neoadjuvant chemoradiotherapy in locally advanced esophageal cancer are highly significant and needed. These markers would allow a tailored treatment to guide non-responders to alternative preoperative therapies and ultimately avoid ineffective, costly and seriously cytotoxic treatments. Results of most studies on biomarkers for predicting response to neoadjuvant chemoradiotherapy in esophageal cancer are promising. The potential utilization of biomarkers in clinical practice is urgently expected and needed, which plays an important role in guiding and improving the individualization of multimodality therapy in locally advanced esophageal cancer.

OBJECTIVETo analyze the prognostic factors for esophageal carcinoma patients with stump carcinoma and atypical hyperplasia after esophagectomy.

METHODSFrom August 2006 to December 2010, 182 esophageal carcinoma patients with stump carcinoma and atypical hyperplasia after esophagectomy treated in our hospital were involved in this study, including 60 cases with grade I-II atypical hyperplasia, 23 cases with grade III atypical hyperplasia, 37 cases with carcinoma in situ, and 62 cases with invasive carcinoma. Prognostic factors for these patients were analyzed.

RESULTSThe 1-, 2-, 3- and 4-year locoregional control rates of these 182 patients were 77.1%, 63.3%, 60.3% and 60.3%, respectively, and the over-all cumulative survival rates were 78.6%, 63.9%, 46.3% and 41.0%, respectively. A total of 56 cases suffered from locoregional recurrence (56/182, 30.8%), including anastomotic recurrence and lymph node metastasis. The number of locoregional recurrence patients of grade I-II of atypical hyperplasia was 13(13/60, 21.7%), grade III atypical hyperplasia and carcinoma in situ 21 (21/60, 35.0%), and invasive carcinoma 22 (22/62, 35.5%). There were no significant differences among the three groups(χ(2) = 3.485, P = 0.175). There were significant differences in locoregional control rate and survival rate among the four treatment groups (P < 0.05). For patients with stump grade I∼II atypical hyperplasia and different stage positive stump margin, the 1-, 2-, 3- and 4-year survival rates of the four treatment groups had significant differences (P < 0.05). As for locoregional control rates, there were no significant differences in the four groups (P > 0.05). Univariate analysis showed that tumor length, depth of invasion, number of metastatic lymph nodes, number of lymph node metastatic fields, pTNM stage, stump pathological grade and treatment modality were main influencing factors for survival rate (P < 0.05);invasion depth, stump pathological grade and treatment modality were important factors for locoregional control. Multivariate Cox regression analysis showed that tumor length, number of metastatic lymph nodes, stump pathological grade and treatment modality were independent influencing factors for survival (all P < 0.05);invasion depth, stump pathological grade and treatment modality were independent influencing factors for locoregional control (all P < 0.05).

CONCLUSIONSFor the patients with stump carcinoma and atypical hyperplasia after esophagectomy, tumor length, number of metastatic lymph nodes, stump pathological grade and treatment modality are independent influencing factors for long-term survival, and invasion depth, stump pathological grade and treatment modality are independent influencing factors for locoregional control.

OBJECTIVETo compare the efficacy and feasibility of neoadjuvant chemoradiotherapy with docetaxel plus cisplatin or with cisplatin plus fluorouracil in the treatment of local advanced esophageal squamous cell carcinoma.

METHODSA total of 154 cases in the stage of cT3N0-1M0 were randomly assigned to two arms. The arm A received 2 cycles of doctaxel 75 mg/m(2) plus cisplatin 25 mg/m(2) d1-3 and 40 Gy of radiation therapy, and the arm B received 2 cycles of cisplatin 25 mg/m(2) d1-3 plus fluorouracil 600 mg/m(2) d1 ∼ 5 and 40 Gy of radiation therapy. The surgery was performed 3 - 4 weeks later.

RESULTSGrade 3/4 toxicities occurred in 53.2% of the patients in arm A and in 36.4% of the patients in arm B (P = 0.035). Neutropenia occurred in 20.7% of the patients in arm A and 5.6% of the patients in arm B (P = 0.004). Nine patients aborted surgery due to tumor progression. 71 patients underwent resection in 73 cases of the arm A and 69 patients underwent complete resection, 70 patients underwent resection in 72 cases and 70 complete resection of the arm B, respectively (P > 0.05). No mortality was noted. The overall complication rate was similar in the two arms (21.9% vs. 23.6%). Pathological complete response was achieved in 27 patients (35.1%) in the arm A and 16 patients (20.8%) in the arm B (P = 0.048).

CONCLUSIONSNeoadjuvant chemoradiotherapy with docetaxel plus cisplatin can be well tolerated and achieves a higher pathological complete response rate than with cisplatin plus fluorouracil.

OBJECTIVEThe extrapulmonary small cell carcinoma (EPSCC), a uncommon malignant tumor, has seldom been reported. The aim of this study was to analyze the clinical characteristics, treatment and prognosis of EPSCC.

METHODSThe clinical data of 243 patients admitted in our hospital from 1977 to 2007 were reviewed. The survival rate was calculated by the Kaplan-Meier method and log-rank test.

RESULTSThe median age of the patients was 58 years and the male-to-female ratio was 2.47:1. According to VALSG criteria, 209 patients had limited disease (LD) and 34 had extensive disease (ED). 170 patients received chemotherapy-based multimodal therapy, 73 received surgery, and/or radiotherapy. The 6, 12, 24, 36 and 60-month survival rates of these patients were 88.9%, 67.2%, 36.8%, 27.3% and 18.3%, respectively. The clinical stage, vessel involvement and regional lymph node metastases were independent prognostic factors of EPSCC. Patients with LD had a median overall survival of 18.6 months compared with 14.0 months in patients with ED (P = 0.030). The median survival was 19.2 months for the patients without vessel involvement and 14.4 months with vessel involvement (P = 0.026). The median survival of the patients with regional lymph node metastases was 13.9 months, while 39.5 months without regional lymph node metastases (P = 0.000). Among different primary sites, patients with gynecologic small cell cancer had a median survival of 28.0 months, head and neck 20.1 months and gastrointestinal tract 14.3 months. Brain metastasis was observed in a lower number of patients with EPSCC compared with that in patients with SCLC. There were no statistically significant differences in overall survival between patients with pure and mixed EPSCC (P = 0.396).

CONCLUSIONEPSCC is an uncommon malignant tumor with early metastasis and poor prognosis. The clinical characteristics of EPSCC and SCLC were similar in some aspects, however, there are some differences in etiology, clinic course, survival and frequency of brain metastases. These differences may influence the choice of therapeutic strategy. Multimodal therapy, combination of chemo- and radio-therapy after surgical resection may improve the outcome of EPSCC.

BACKGROUND/AIMS: This study was designed to compare the survival rates between patients with localized esophgeal cancer who were treated with concurrent chemoradiation therapy without surgery and patients who were treated with concurrent chemoradiation therapy including surgery. METHODS: Eighty-eight patients from January 1997 to December 2005 with locally advaned resectable esophageal cancer were selected and retrospectively analyzed. Survival period was defined as the time to death from the date of diagnosis or mid-monitor period of December 2005. Sixty-one patients were treated with chemoradiation therapy alone while twenty-seven patients were treated with chemoradiation therapy in addition to surgery as for curative intention. As for radiation therapy, 5,000-5,500 cGY was used. 5-Fluouracil and cisplatin were used for chemotherapy. The primary end point was overall survival time. The secondary end point was overall progression free survival time. RESULTS: There was no significant difference in tissue type, location and clinical staging, but the median age was significantly younger in the group treated with surgery (63.4 years) than the group treated without surgery (68.8 years). Median period analyzed was 17.3 months. Five year survival rate for the group with chemoradiation alone was 7.4% and 4% for the group with surgery. The median survival rate was 11+/-3 months for the group with chemoradiation alone and 10+/-6 months for the group with surgery, in which there was no statistical difference (p=0.697). CONCLUSIONS: There was no significant increase in survival rate in patients who were treated by chemoradiation with surgery compared with chemoradiation alone. Further analysis in terms of prospective study is needed.
