Recent advances in multimodality treatment offer excellent opportunities to rethink the paradigm of perioperative management for locally advanced esophageal squamous cell carcinoma. One treatment clearly doesn't fit all in terms of a broad disease spectrum. Individualized treatment of local control of bulky primary tumor burden (advanced T stage) or systemic control of nodal metastatic tumor burden (advanced N stage) is essential. Given that clinically applicable predictive biomarkers are still awaited, therapy selection guided by diverse phenotypes of tumor burden (T vs. N) is promising. Potential challenges regarding the use of immunotherapy may also boost this novel strategy in the future.

BACKGROUND: Surgery was not standard-of-care of patients with advanced lung cancer. However, a serial of retrospective studies demonstrated that thoracic dissemination (M1a) patients could benefit from contraindicated surgery. After non-standard treatment, how should these patients choose following treatment approaches? Herein, we conducted this retrospective study to explore subsequent optimal treatment approaches. METHODS: Different therapeutic approaches were evaluated by comparing progression-free survival (PFS), overall survival (OS), time to treatment interval (TTI) using the Kaplan-Meier method and Log-rank test. A Cox proportional hazards regression model was used for multivariate analysis. RESULTS: 141 eligible were enrolled. The median PFS of chemotherapy group, targeted therapy group and observation group were 14.7, 41.0 and 31.0 months, respectively (95%CI: 19.01-26.01; P<0.001). There was no significantly statistically difference between median PFS of targeted group and observation group (P=0.006). The median OS were 39.0, 42.6 and 38.1 months (95%CI: 32.47-45.33; P=0.478). The median PFS and OS of TTI<3 months and TTI ≥3 months were 15.2 months versus 31.0 months (95%CI: 19.01-26.06; P<0.001) and 41.7 months versus 38.7 months (95%CI: 32.47-45.33; P=0.714). Multivariate analyses revealed gender (P=0.027), lymph node status (P=0.036) and initial therapy (P<0.001) were independent prognostic factors for PFS. CONCLUSIONS Observation did not shorten survival of thoracic dissemination patients with lung adenocarcinoma or squamous carcinoma, therefore, it could be an favorable option. But prospective randomized controlled study was needed to confirm its validity.

OBJECTIVETo evaluate the patterns of recurrence and the related factors in patients with pT3N0M0 thoracic esophageal squamous cell carcinoma (ESCC) after two-field esophagectomy.

METHODSFrom Jan 2008 to Dec 2009, 208 patients with stage pT3N0M0(2002, UICC) thoracic ESCC were treated with two-field esophagectomy in our hospital. There were 138 males and 70 females, and the median age was 60 years old (range 33-78). There were 33 patients in the upper-, 134 in the middle-, and 41 in the lower-thoracic esophagus, with a median length of lesion of 5 cm. There were 32 patients with no-, 78 with mild- and 98 patients with severe adhesions at surgery. The median number of dissected lymph nodes was 9 (range 1-27). 98 patients were treated with surgery alone and 110 with postoperative adjuvant chemotherapy. The statistical analysis was conducted using SPSS 13.0 software.

RESULTSThe follow-up was ended on July 2013. In the total group of 208 patients, the total recurrence rate was 41.8% (87/208). Among them, 52 patients had locoregional recurrence (LR), 15 had distant metastasis (DM) and 20 patients had both local recurrence and distant metastasis. 40.2% (35/87) of all recurrences were found within one year after operation, 67.8% (59/87) within 2 years, 86.2% (75/87) within 3 years, and 100% (87/87) within 4 years. The 1-, 3-, and 5-year progression-free survival (PFS) rate was 83.0%, 62.8% and 56.3%, respectively. The overall locoregional recurrence rate was 34.6% (72/208), among them, 9 cases had recurrence in the cervix (all were supraclavicular lymph node metastasis), 66 cases in the mediastinum and 4 cases had para-aortic lymph node metastasis. 83.3% (60/72) of the locoregional recurrence was located in the carinal region or upper area. The 1-, 3-, 5-year locoregional recurrence rate was 15.6%, 32.2%, and 36.8%, respectively, and the median time of recurrence was 15.5 months. The overall distant metastasis (DM) rate was 16.8% (35/208). The 1-, 3-, and 5-year DM rate was 4.4%, 15.3%, and 20.1%, respectively, and the median time of DM was 24 months. The most common site of DM was the lung and bone. The univariate analysis showed that age and tumor site were associated with PFS, tumor site and small lymph node in the mediastinum (diamter <1 cm) before surgery were related with LR (P<0.05 for all), and tumor site, histological differentiation and LR were related with distant metastasis after surgery (P<0.05). Multivariate analysis showed that the tumor site was an independent prognostic factor affecting the progression-free survival and locoregional recurrence (P<0.05), and histological differentiation and LR were independent factors associated with distant metastasis (P<0.05 for all).

CONCLUSIONSThe recurrence rate is very high in patients with pT3N0M0 thoracic ESCC after surgery, and most of them occur within 3 years after operation. Locoregional recurrence occurs more frequently and shortly than distant metastasis, and most of LR is located in the carinal region or upper-mediastinum. LR rate in upper-thoracic ESCC is very high, therefore, postoperative radiotherapy (PORT) is strongly suggested. LR rate in middle thoracic ESCC is also rather high and PORT is suggested. LR occur much less in the lower-thoracic ESCC, thus, PORT is not suggested routinely. Patients with poorly differentiated ESCC and LR have a high rate of distant metastasis.

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.

OBJECTIVETo analyze the clinical and pathologic risk factors of early recurrence in patients with pathological N1 (pN1) stage esophageal squamous cell carcinoma after radical esophagectomy.

METHODSA retrospective study was carried out on 95 consecutive pN1 stage esophageal squamous cell carcinoma patients undergoing esophagectomy with lymphadenectomy by the same surgical team from January 2004 to December 2010 was performed. The Cox proportional hazards model was used to determine the independent risk factors for recurrence and metastasis within 3 years after the operation.

RESULTSRecurrence was identified in 52 patients (54.7%) within 3 years after operation. Local recurrence was found in 42 patients (44.2%), and distant metastasis in 10 patients (10.5%). The Cox multivariate analysis showed that pT3-4a stage (RR=3.604, P=0.027), positive lymph node metastasis in two stations (RR=4.834, P=0.009) or two fields (RR=5.689, P=0.003), and postoperative adjuvant chemotherapy (RR=1.594, P=0.048) were independent risk factors for postoperative recurrence.

CONCLUSIONSPostoperative adjuvant chemotherapy can decrease the probability of postoperative recurrence and metastasis of pN1 esophageal squamous cell carcinoma. As for patients who are identified as multi-station or multi-field lymph node metastasis, preoperative induced therapy maybe further improve treatment outcomes.

OBJECTIVETo study the clinicopathologic features, histologic diagnosis and differential diagnosis of primary mucosal tuberculosis (TB) in the head and neck region.

METHODSForty-seven cases of primary mucosal TB of the head and neck region were studied by hematoxylin-eosin and Ziehl-Neelsen stains. The clinical and pathologic features were analyzed with review of the literature.

RESULTSThe patients included 26 male and 21 female, with mean age 47.1 years (range 14-84 years). There were three sinonasal TB, 19 nasopharyngeal TB, two oropharyngeal TB, 18 laryngeal TB, four middle ear TB, one salivary gland TB and one laryngeal TB complicating laryngeal cancer. The initial symptoms were nasal obstruction, mucopurulent rhinorrhea, epistaxis, snoring, hoarseness, dysphagia, odynophagia, serous otitis, hearing loss, tinnitus, and otalgia. Physical examination result was variable, from an apparently normal mucosa, to an evident mass, or a mucosa with an adenotic or swollen appearance, ulcers, leukoplakic areas, and various combinations thereof. CT and MRI findings included diffuse thickening, a soft-tissue mass, calcification within the mass and bone destruction resembling malignancy. Histologic examination showed granulomas with a central necrotic focus surrounded by epithelioid histiocytes and multinucleated Langhan's giant cells. Acid-fast bacilli were difficult to demonstrate but found in 13/45 cases. Follow-up data were available in 42 patients.

CONCLUSIONSPrimary TB arising in the head and neck mucosa is rare. It may mimic or co-exist with other conditions. The characteristic histopathology is a granuloma with central caseous necrosis and Langhans'giant cells. Identification of acid-fast bacilli and bacteriologic culture confirm the diagnosis of mycobacterial disease.

OBJECTIVEPure epithelial breast metaplastic carcinoma is a rare and highly malignant tumor. In this study, our purpose was to analyze the clinical features, treatment method and prognostic factors, so to explore the approach for early diagnosis and appropriate treatment of this cancer.

METHODSClinical data of 22 patients with histopathologically confirmed pure epithelial breast metaplastic carcinoma and treated at Tianjin Cancer Hospital from 1974 to 2008, were reviewed retrospectively. Survival rate was calculated by life tables. Kaplan-Meier unvariate analysis and Log-rank test were used to compare the survival rates. Multivariate factors for survival were analyzed by Cox proportional hazards regression model.

RESULTSThe median age of the 22 cases of pure epithelial breast metaplastic carcinoma was 52.5 years. Among them 20 cases went to see a doctor for painless mass, and two cases shown as skin inflammation. Clarifying a diagnosis was difficult before operation so that its diagnosis mainly depended on postoperative histopathologic examination. Twelve cases had axillary lymph node metastasis, 7 cases distant metastasis, and the lung was the most common metastatic organ. The 5-year survival rate was 55.6%, with a median follow-up of 46 months. It was found by Kaplan-Meier unvariate analysis that the age (P = 0.044), number of positive axillary lymph nodes (P = 0.011) and therapeutic schedule (P = 0,003) significantly influenced the outcome of the patients, but tumor size (P = 0.194) was not. Cox multivariate analysis results showed that number of positive axillary lymph nodes was independent prognostic factor for pure epithelial breast metaplastic carcinoma (P = 0.038).

CONCLUSIONSPure epithelial breast metaplastic carcinoma is seldom seen. It is easy to cause distant metastasis and has a poor prognosis. ER, PR and HER-2 expressions in most samples are negative. The more axillary lymph nodes have metastasis, the poorer is the prognosis. A reasonable and comprehensive treatment can improve the prognosis obviously.

Oral squamous cell carcinoma (OSCC) is a common malignant tumor of the head and neck, and recurrence is an important prognostic factor in patients with OSCC. We explored the factors associated with recurrence of OSCC and analyzed the survival of patients after recurrence. Clinicopathologic and follow-up data of 275 patients with OSCC treated by surgery in the Cancer Institute and Hospital of Tianjin Medical University between 2002 and 2006 were analyzed. Recurrence factors were analyzed with Chi-square or Fisher's exact test and multivariate analysis. The prognosis of patients after recurrence was analyzed with the Kaplan-Meier method and log-rank test. The recurrence rate was 32.7%. The recurrence time ranged from 2 to 96 months, with a median of 14 months. Univariate analysis showed that T stage, degree of differentiation, pN stage, flap application, resection margin, and lymphovascular invasion were factors of recurrence (P < 0.05). Multivariate analysis showed that T stage, degree of differentiation, and pN stage were independent factors of recurrence (P < 0.001). The differences in gender, age, tumor site, region of lymph node metastasis, and perineural invasion between the recurrence and non-recurrence groups were not significant (P > 0.05). Kaplan-Meier and log-rank tests showed that the 2- and 5-year survival rates were significantly lower in the recurrence group than in non-recurrence group (67.6% vs. 88.0%, 31.8% vs. 79.9%, P < 0.001). Therefore, to improve prognosis, we recommend extended local excision, flap, radical neck dissection, and adjuvant chemoradiotherapy for patients more likely to undergo recurrence.
