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 compare the therapeutic effect and adverse effects of two regimens, namely cisplatin and docetaxel (DC) regimen and fluorouracil (PF) regimen, both with concurrent radiotherapy, in the treatment of advanced esophageal squamous cancer.

METHODSForty-eight patients with esophageal squamous cancer were randomly assigned in DC regimen and PF regimen groups. All the patients received conventional radiotherapy at a total dose of 60 Gy (in 30 fractions) for 6 weeks. In DC regimen group, the patients received intravenous infusion of docetaxel (75 mg/m(2)) for 1 h on day 1 and DDP (25 mg/m(2) daily) on days 1-3, with every 28 days as one cycle. PF regimen consisted of cisplatin (25 mg/m(2)) on days 1-3 and continuous intravenous infusion of fluorouracil (500 mg/m(2)) for 5 days, with every 28 days as one cycle. All the patients were suggested to have no less than 2 cycles.

RESULTSThe 3-year median survival time in DC regimen was slightly longer than that in PF regimen group (26 vs 23 months, Χ2=3.4041, P=0.065). The same result was also found in the short-term effect and adverse reactions including ?myelosuppression and gastrointestinal reactions. Only the adverse reaction of radiotherapy-induced esophagitis showed a significant difference between the two groups (P=0.049).

CONCLUSIONDC regimen with synchronous radiotherapy is effective and safe for treating advanced esophageal squamous cancer.

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.

PURPOSE: We report the outcomes of patients treated with palliative radiotherapy (pRT) to the primary tumour in the context of well-controlled metastatic disease after initial chemotherapy. MATERIALS AND METHODS: Clinical records of 132 patients with metastatic esophago-gastric (OG) cancer treated with palliative chemotherapy (pCT) between January 2009 and June 2013 were reviewed. Ninetyseven patients had responding or stable disease after 3 months of chemotherapy, of whom 53 patients received pRT to the primary tumour after initial chemotherapy in the presence of well-controlled metastatic disease (group A, pCT-RT). The remaining 44 patients were treated with pCT alone (group B, pCT). Treatment-related outcomes were assessed in above groups including time to local progression (TTLP), progression-free and overall survival. RESULTS: The median overall survival for patients treated with pRT after initial chemotherapy (group A) was 23.3 months (95% confidence interval [CI], 17.70 to 28.89 months) and significantly higher than the 14 months (95% CI, 10.91 to 17.08 months) in patients treated with pCT alone (group B) (p < 0.001). The use of pCT-RT was an independent predictor of OS in multivariate analysis. Local recurrence was observed in 12/53 of patients (23%) in group A compared to 16/44 (36%) in group B. The median TTLP was significantly higher in patients after pCT-RT at 17.3 months (5.23 months to 44.50 months) compared to 8.3 months (range, 4.10 to 25.23 months) in patients treated with pCT alone (p=0.006). CONCLUSION: The possibility of pRT influencing systemic disease in advanced OG cancer has not been reported, and results from the present study present strong arguments for investigation of this therapeutic strategy in a randomized trial.

Esophageal cancer is still a virulent disease that leads to death. Surgery has been regarded as the treatment of choice in patients suffering this type of cancer and recent improvements in surgical techniques and perioperative management have significantly increased the resection rate and reduced the operative mortality. Nevertheless, long-term survival rates remain poor. The poor prognosis reflects the fact that the disease is usually advanced at the time of diagnosis. Therefore, a combination of chemotherapy and radiotherapy has recently been developed as a treatment for advanced esophageal cancer patients. Chemoradiation therapy is based on the concept of the biochemical modulation effects and radiosensitizing effects of the chemotherapeutic agents. How ever, the optimal choice of chemotherapeutic agents and their doses, as well as the chemotherapy and radiotherapy regimens have not been precisely established. We report a case of concurrent chemoradiation protocol by which a complete response was achieved. 5-FU (1,800 mg/body/day) was continuously infused over 24 hours and cisplatin (45 mg/ body/day) was administered 1 hour before radiotherapy for 3 days. This chemotherapy course was repeated once more after 4 weeks. The radiotherapy (180 cGy/day) was scheduled for 5 consecutive days, followed by a 2-day withdrawal, and a total dose of 5,940 cGy within 7 weeks. Our concurrent chemoradiation therapy is deemed rational, effective and safe because an endoscopically and pathologically complete response was achieved 1 year after chemoradiation therapy without any severe side effects. Therefore, we believe that our concurrent chemoradiation therapy can be recommended as a treatment for advanced esophageal cancer patients.

PURPOSE: To evaluate the efficacies and toxicities of concurrent chemoradiotherapy (CCRT), with or without intraluminal brachytherapy (ILB), using a retrospective analysis in esophageal carcinomas with respect to survival. MATERIALS AND METHODS: From April 1995 to July 2001, a total of 65 patients, diagnosed with an esophageal carcinoma, were treated by CCRT, with 21 also treated by ILB after CCRT. External radiotherapy was performed using 6 or 10 MV X-rays, with a dose range of 46.8~69.6 Gy (median; 59.4). The ILB was performed using high-dose-rate brachytherapy with Ir-192. The fractionation of ILB was 3 Gy by 4, or 5 Gy by 2 fractions. Cisplatin (75 mg/m2) was given on each first day of weeks 1, 5, 9 and 13, and 5-FU (1,000 mg/m2) as a continuous infusion for the first 4 days of each course. RESULTS: The median survival time of all patients was 15 months, and the 1, 2 and 3-year survival rates were 55.4, 29.2 and 20.7%, respectively. The 2-year survival rates of the patients with and without ILB were 33.3 and 27.3%, respectively (p=0.80). The 2-year survival rates of the patients with a complete, partial and no response were 44.1, 13.8 and 0%, respectively (p=0.02). The response to treatment was the only significant factor affecting the overall survival from a multivariate analysis. CONCLUSIONS: This study has shown that the survival outcomes of CCRT were much better than previous results with radiotherapy alone. However, the addition of ILB after CCRT showed no advantage over that of CCRT alone.

Objective: To evaluate the long-term outcomes, failure patterns and prognostic factors of definitive radiotherapy in patients with cervical esophageal carcinoma (CEC). Methods: We retrospectively reviewed the clinical data of 148 CEC patients who treated with definitive radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2001 to December 2017. The median radiation dose was 66 Gy (59.4-70 Gy) and 33.1% of patients received concurrent chemotherapy. The Kaplan-Meier method was used to calculate survival rates. The log rank test was used for survival comparison and univariate prognostic analysis. The Cox model was used for multivariate prognostic analysis. Results: The median follow-up time was 102.6 months. The median survival time, 2- and 5-year overall survival (OS) were 22.7 months, 49.9% and 28.3%. The median, 2- and 5-year progression-free survival were 12.6 months, 35.8% and 25.8%. The 2- and 5-year locoregional recurrence-free survival were 59.1% and 50.8%. The 2- and 5-year distant metastases-free survival were 74.6% and 65.9%. Multivariate analysis showed that EQD(2)>66 Gy was the only independent prognostic indicator for OS (P=0.040). The median survival time and 5-year OS rate significantly improved in patients who received EQD(2)>66 Gy than those who received≤66 Gy (31.2 months vs. 19.2 months, 40.1% vs. 19.1%, P=0.027). A total of 87 patients (58.8%) developed tumor progression. There were 50 (33.8%), 23 (15.5%) and 39 (26.4%) patients developed local, regional recurrence and distant metastases, respectively. Eleven patients (7.4%) underwent salvage surgery, and the laryngeal preservation rate for entire group was 93.9%. Conclusions: Definitive radiotherapy is an effective treatment for cervical esophageal carcinoma with the advantage of larynx preservation. Local recurrence is the major failure pattern. EQD(2)>66 Gy is associated with the improved overall survival.

PURPOSE: The outcomes of a surgical approach for patients with an esophageal carcinoma remain unsatisfactory despite its high complication rates. We conducted a phase II trial, using combined FP (5-fluorouracil and cisplatin) chemotherapy and concurrent radiotherapy, as a definitive therapy for patients with esophageal cancer. MATERIALS AND METHODS: Patients with histologically proven esophageal cancer were enrolled onto this study. The treatment consisted of four courses of chemotherapy and six and a half weeks of radiotherapy. The patients received chemotherapy in weeks 1, 5, 12 and 16 (5-fluorouracil 1, 000 mg/m2 on days 1 to 4 and cisplatin 75 mg/m2 on day 1). Radiotherapy was administered at a dose of 59.4 Gy, in five 1.8 Gy fractions a week. RESULTS: A total of 22 eligible patients entered the study. Of the 19 evaluable patients, a complete response occurred in 7 (37%), and a partial response in 8 (42%). After a median follow-up of 35 months, the overall survival rate was 32% at three years and the median survival was 11 months. Fourteen (64%) received planned dose of radio-therapy and 13 (59%) received more than three courses of chemotherapy. However, there was no difference in three-year survival rates between the patients that received less than three courses of chemotherapy and those that received three or more courses (31% vs. 32%). The major treatment related toxicity was mucositis, which developed in every patient, with grades III or IV in thirteen (59%) patients. During the treatment, the patients lost, on average, 3.8% of their body weight. The mean hospital stay was 23 days, with a total duration of treatment of 74 days. CONCLUSIONS: Concurrent FP chemoradiotherapy was effective as a definitive therapy for patients with esophageal cancer. The major toxicity was mucositis. Although the treatment was relatively feasible, a randomized trial of reduced courses of chemotherapy is warranted.

This is a retrospective study of 62 patients with unresected squamous cell carcinoma of the esophagus treated by radiotherapy alone (25 patients) or combined chemotherapy and radiotherapy (37 patients). Of these, 14 of 25 patients treated by radiation therapy alone and 25 of 37 patients treated by combined chemotherapy and radiotherapy completed radiotherapy consisting of 55 to 60 Gy in 5 to 6 weeks and were analyzed for local control rate and survival rate. Follow up ranged from 6 days to 58 months. Three (8%) of 39 patients had a complete response, twenty-eight(72%) a partial reponse and eight(20%) minimal or no resonse. Overall median survival was 11 months for all stages. The 1 year and 2 year actuarial survival rates were 48.6% and 13% respectively. Age and stage had prognostic significances (p<0.05, p<0.05 respectively). The 1 year survival rate was 70.1% for stage I, 47.6% for stage II, and 28.4% for stage III. The median survival was 19 months for stage I, 11 months for stage II, 6 months for stage III, and 5.5 months for stage III with distant metastases. The 1 year survival rate of patients 55 years and above was 69.6%, 54 years and below was 0%. There was no significant difference in survival rate between treatment modalities, locations of tumor, and responses of tumor.

Metastatic cancers in the spermatic cord are extremely rare. A 79-year-old man, who had undergone palliative chemotherapy and radiotherapy one year previously, due to inoperable esophageal cancer, visited our hospital suffering from right inguinal swelling. Ultrasonography showed echogenic lesions superior to the right testis, suspicious of a swollen bowel loop. An emergency exploration revealed no bowel content or mesentery, but with thickened of the spermatic cord and epididymis four times that of the contralateral side. Pathology confirmed a metastatic carcinoma, likely to have originated from the esophagus.
