From March 1992 to October 1997, a total of 38 patients with histologically proven
esophageal cancer
received combination therapy of daily low-dose cisplatin (CDDP) and radiation therapy. The clinical stages (UICC 1997) were I in 3, IIA,B in 13, III in 13, and
IVA
in 9 patients. CDDP (5 mg/m2) was administered intravenously with 100 ml saline 30 min before each irradiation from Monday to Friday. All patients received at least 60 Gy of radiation therapy. The average number of CDDP administrations was 23, and the mean total CDDP dose was 115 mg/m2. Of the 38 patients, 14 patients completed full course of chemoradiation therapy. The overall survival rates at 1, 2, and 5 years were 51%, 19%, and 8%, respectively. The median survival period was 12 months. The objective response rate was 82% with 11 (29%) CR. Survival of the stage II-
IVA
patients who received daily low-dose CDDP and radiation therapy was a little better than that of historical control patients who were treated by radiation therapy alone. Most of the patients experienced nausea. Grade 3 esophagitis was observed in two (5%) patients. Grade 4 leukocytopenia and thorobocytopenia were observed in one (3%) and two (5%) of the patients, respectively. Except for leukocytopenia (18%), frequencies of toxicity of grade 3 or more were less than 10%. Although the results indicate that daily low-dose CDDP combined with radiation therapy may slightly improve the survival of
esophageal cancer
patients with acceptable toxicity, further efforts should be made to optimize clinical trial protocols. Escalation of daily CDDP dose should be considered to obtain a more effective radiosensitizing effect.

Histopathological tumor regression grade (TRG) has been shown to be a prognostic factor in patients with
esophageal cancer
after neoadjuvant radiochemotherapy (RCT). The system introduced by Mandard to group TRG (Cancer 1994;73:2680-2686) has been used to analyse and discuss its prognostic significance on survival in a single institution retrospective analysis: TRG 1 (complete regression) - TRG 5 (absence of regressive changes). Sixty patients with locally advanced (T3/4 or N1) adenocarcinoma or squamous cell carcinoma received cisplatin-based RCT. Three to four weeks later operation for curative intent was performed. Median follow-up was 17.7 months. Histopathological tumor stages were stage 0 in 17%, stage I in 10%, stage II in 60%, stage III in 12% and stage
IVA
in 1%. The 5-year overall survival (OS) rate was 35%. In univariate analysis, ypN-status and TRG correlated significantly with OS (P = 0.004, P = 0.0008, respectively). While OS of TRG 1 differed significantly from all other groups, no differences in OS between the other TRG groups were seen. Patients with complete tumor regression after neoadjuvant RCT showed a much better survival than patients with tumors that responded less to induction therapy. Further qualitative subdivision of tumor regression could not identify patient groups with significant differences in prognosis. After comparing our data with the literature, it is reasonable to consider classifying all patients into 'Complete tumor regression' and 'Incomplete tumor regression'.

We report analytic and consensus processes that produced recommendations for neoadjuvant pathologic stage groups (ypTNM) of esophageal and esophagogastric junction cancer for the AJCC/UICC cancer staging manuals, 8th edition. The Worldwide
Esophageal Cancer
Collaboration provided data for 22,654 patients with epithelial esophageal cancers; 7,773 had pathologic assessment after neoadjuvant therapy. Risk-adjusted survival for each patient was developed. Random forest analysis identified data-driven neoadjuvant pathologic stage groups wherein survival decreased monotonically with increasing group, was distinctive between groups, and homogeneous within groups. An additional analysis produced data-driven anatomic neoadjuvant pathologic stage groups based only on ypT, ypN, and ypM categories. The AJCC Upper GI Task Force, by smoothing, simplifying, expanding, and assessing clinical applicability, produced consensus neoadjuvant pathologic stage groups. Grade and location were much less discriminating for stage grouping ypTNM than pTNM. Data-driven stage grouping without grade and location produced nearly identical groups for squamous cell carcinoma and adenocarcinoma. However, ypTNM groups and their associated survival differed from pTNM. The need for consensus process was minimal. The consensus groups, identical for both cell types were as follows: ypStage I comprised ypT0-2N0M0; ypStage II ypT3N0M0; ypStage IIIA ypT0-2N1M0; ypStage IIIB ypT3N1M0, ypT0-3N2, and ypT4aN0M0; ypStage
IVA
ypT4aN1-2, ypT4bN0-2, and ypTanyN3M0; and ypStage IVB ypTanyNanyM1. Absence of equivalent pathologic (pTNM) categories for the peculiar neoadjuvant pathologic categories ypTisN0-3M0 and ypT0N0-3M0, dissimilar stage group compositions, and markedly different early- and intermediate-stage survival necessitated a unified, unique set of stage grouping for patients of either cell type who receive neoadjuvant therapy.

We report analytic and consensus processes that produced recommendations for clinical stage groups (cTNM) of esophageal and esophagogastric junction cancer for the AJCC/UICC cancer staging manuals, 8th edition. The Worldwide
Esophageal Cancer
Collaboration (WECC) provided data on 22,123 clinically staged patients with epithelial esophageal cancers. Risk-adjusted survival for each patient was developed using random survival forest analysis from which (1) data-driven clinical stage groups were identified wherein survival decreased monotonically and was distinctive between and homogeneous within groups and (2) data-driven anatomic clinical stage groups based only on cTNM. The AJCC Upper GI Task Force, by smoothing, simplifying, expanding, and assessing clinical applicability, produced (3) consensus clinical stage groups. Compared with pTNM, cTNM survival was "pinched," with poorer survival for early cStage groups and better survival for advanced ones. Histologic grade was distinctive for data-driven grouping of cT2N0M0 squamous cell carcinoma (SCC) and cT1-2N0M0 adenocarcinoma, but consensus removed it. Grouping was different by histopathologic cell type. For SCC, cN0-1 was distinctive for cT3 but not cT1-2, and consensus removed cT4 subclassification and added subgroups 0,
IVA
, and IVB. For adenocarcinoma, N0-1 was distinctive for cT1-2 but not cT3-4a, cStage II subgrouping was necessary (T1N1M0 [IIA] and T2N0M0 [IIB]), advanced cancers cT3-4aN0-1M0 plus cT2N1M0 comprised cStage III, and consensus added subgroups 0,
IVA
, and IVB. Treatment decisions require accurate cStage, which differs from pStage. Understaging and overstaging are problematic, and additional factors, such as grade, may facilitate treatment decisions and prognostication until clinical staging techniques are uniformly applied and improved.

NLR/Alb (neutrophil lymphocyte ratio/albumin ratio), is a prognostic index for
esophageal cancer
has been confirmed. Prealbumin (PA) is more sensitive to malnutrition than albumin. A new prognostic index, named neutrophil lymphocyte ratio/prealbumin ratio (NLR/PA), for predicting the survival time in patients with esophageal squamous cell carcinoma (ESCC) was proposed.A retrospective study of 315 cases with ESCC was enrolled. The optimal cut-off values were evaluated by ROC curve (the receiver operating characteristics curve). Pearson correlation analyses were used to calculate the correlations among NLR, Alb, NLR/Alb and NLR/PA. The overall survival (OS) was calculated by Kaplan-Meier method. Cox regression analyses were performed to evaluate the prognostic factors.The optimal cut-off value was 0.01 for NLR/PA according to ROC curve. According to multivariate analyses, TNM stage, NLR, NLR/Alb, NLR/PA were prognostic factors for OS. The AUC area (the area under the receiver operating characteristics curves) of the NLR/PA was higher than the areas of NLR and NLR/Alb for all the patients. The index of NLR/ PA had a higher AUC area than that of the index of NLR or NLR/Alb for patients in stage I-II. But in stage III-
IVA
, the index of NLR had a higher AUC area than that of the index of NLR/PA or NLR/Alb.The index of NLR/PA is superior to the index of NLR as a prognostic indicator for patients with early stage (stage I-II) ESCC.

Esophageal cancer
(EC) is a very aggressive tumor, and no reliable prognostic markers exist especially for resectable advanced neoplasia. The principal aim of this study was to investigate the association of germline polymorphisms in nucleotide excision repair (NER) pathway genes with the overall survival (OS) of patients with advanced EC. As a second aim, we also studied the association of NER gene variants with response to cisplatin-based chemotherapy. Among the EC patients referred to our Institution between 2004 and 2012, we selected a cohort of 180 patients diagnosed with a clinical tumor stage ranging from IIB and
IVA
. Patients were genotyped for four NER variants, two in the
ERCC1
(rs11615 and rs3212986) and two in the
ERCC2/XPD
(rs1799793 and rs13181) genes. Kaplan-Meier analyses and Cox proportional hazards model were used to evaluate the associations of the selected variants with OS; association with response to neoadjuvant therapy was investigated using logistic regression. Results showed that the
ERCC1
rs3212986 and the
ERCC2/XPD
rs1799793 were significantly associated with shorter OS. On the contrary, response association analysis displayed that, while rs11615 and rs3212986 in
ERCC1
were associated with response, both
ERCC2/XPD
variants were not. By creating survival prediction models, we showed that the rs3212986 and the rs1799793 have a better predictability of the tumor stage alone. Furthermore, they were able to improve the power of the clinical model (AUC = 0.660 vs. AUC = 0.548,
p
= 0.004). In conclusion, our results indicate that the
ERCC1
rs3212986 and the
ERCC2/XPD
rs1799793 could be used as surrogate markers for a better stratification of EC patients with advanced resectable tumor.

Purpose To assess the treatment results of definitive radiotherapy for
esophageal cancer
at Tokushima University Hospital and clarify the prognostic factors. Methods Seventy consecutive patients with
esophageal cancer
who underwent definitive radiotherapy between May 2004 and March 2012 were included in the present study. Local control rate, overall survival rate, and radiation morbidity were examined and univariate and multivariate analyses were performed to investigate prognostic factors. Results The 5-yearoverall survival rates of stages I, II, III, and
IVA
were 81%, 71%, 0%, and 9%, respectively. Performance status, clinical stage, and neoadjuvant chemotherapy were significant prognostic factors. A past history of interstitial pneumonia was associated with severe radiation-induced lung injury. Conclusions Patients who underwent definitive chemoradiotherapy for
esophageal cancer
in stage I/II showed good prognosis. However, treatment results of the patients in stage III/IV were not satisfactory, and those who could not undergo surgery after neoadjuvant chemotherapy had the worst prognosis.J.Med.Invest.66:99-105, February, 2019.

Postoperative chylothorax after esophagectomy is a relatively rare complication, but treatment can sometimes be complicated. We report 3 cases of Lipiodol lymphangiography via inguinal lymph node puncture that was effective for chyle leakage occurring after esophagectomy. Case 1: A 67-year-old man with stage IIIA esophageal squamous cell carcinoma underwent radical esophagectomy by video-assisted thoracic surgery (VATS) following neoadjuvant chemotherapy (NAC). After enteral feeding, right pleural effusion drainage increased sharply and changed to white color that was diagnosed as chylothorax. Conservative treatment was started on postoperative day (POD) 15. On POD 50, intranodal Lipiodol lymphangiography and thoracic duct ligation were performed, resulting in complete improvement by the next day. Case 2: A 69-year-old man with stage IIIC
esophageal cancer
was treated salvage operation following chemoradiation. Postoperative chylothorax was diagnosed on POD 6. Despite conservative treatment, the pleural fluid volume did not decrease. Intranodal Lipiodol lymphangiography performed on POD 13 showed contrast medium draining from the thoracic duct near the tracheal bifurcation. Thoracotomy for thoracic duct ligation was performed on POD 15. Thereafter, drainage from the thoracic drain decreased significantly, and the right thoracic drain was removed 4 days later. Case 3: A 65-year-old man with Stage
IVA
hypopharyngeal cancer and Stage IIIA
esophageal cancer
underwent total pharyngopharyngeal esophagectomy by VATS following NAC. Postoperative chylothorax was diagnosed on POD 7. Despite conservative treatment, the pleural fluid volume did not decrease. Intranodal Lipiodol lymphangiography performed on POD 19 completely visualized the thoracic duct and showed no outflow of contrast from the main thoracic duct into the mediastinum. Pleural fluid decreased remarkably after lymphangiography. Intranodal Lipiodol lymphangiography for postoperative chylothorax accurately visualizes flow within the thoracic duct and clearly depicts its positional relationship with other organs. Besides lymphangiography is not only helps to determine the site of chyle leakage but can also be effective for curing chylothorax by less invasive and safer method.
