BACKGROUND: Skin cancer is the most common type of cancer. Of the 4 million skin lesions excised annually worldwide, approximately 2 million are considered cancerous. In this study, we aimed to describe a regional experience with skin cancers treated by a single senior surgeon and to provide a treatment algorithm. METHODS: The medical records of 176 patients with head and neck non-melanocytic skin cancer (NMSC) who were treated by a single surgeon at our institution between January 2010 and May 2016 were retrospectively reviewed, and their data (age, sex, pathological type, tumor location/size, treatment modality) were analyzed. Patients with cutaneous squamous cell carcinoma (cSCC) who were classified as a high-risk group for nodal metastasis underwent sentinel node mapping according to the National Comprehensive Cancer Network guidelines. RESULTS: Among the patients with NMSC who were treated during this period, basal cell carcinoma (BCC; n=102, 57.9%) was the most common pathological type, followed by cSCC (n=66, 37.5%). Most lesions were treated by complete excision, with tumor-free surgical margins determined via frozen section pathology. Thirty-one patients with high-metastasis-risk cSCC underwent sentinel node mapping, and 17 (54.8%) exhibited radiologically positive sentinel nodes. Although these nodes were pathologically negative for metastasis, 2 patients (6.5%) later developed lymph node metastases. CONCLUSION: In our experience, BCC treatment should comprise wide excision with tumor-free surgical margins and proper reconstruction. In contrast, patients with cSCC should undergo lymphoscintigraphy, as nodal metastases are a possibility. Proper diagnosis and treatment could reduce the undesirably high morbidity and mortality rates.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis, treatment and prognosis of patients with primary gastric adenosquamous cell carcinoma.

METHODSA total of 5 562 patients with gastric neoplasm were admitted in Tianjin Medical University Cancer Institute and Hospital from January 2001 to January 2011. Among them 42 patients were diagnosed as primary gastric adenosquamous cell carcinoma, accounting for 0.76% of all the patients. The clinicopathological and follow-up data of these 42 patients with primary gastric adenosquamous cell carcinoma were retrospectively analyzed, and Cox proportional hazard model was used to analyze the prognostic factors of gastric adenocarcinoma squamous cell carcinoma.

RESULTSAmong above 42 patients, 32 were male and 10 were female, with a male-to-female ratio of 3.2/1.0 and the average age was 63 years (range: 46 to 77 years). Five patients (11.9%) were confirmed as adenosquamous cell carcinoma by preoperative pathological examination, while other 37 patients were diagnosed as adenocarcinoma preoperatively. According to the 7th edition AJCC TNM classification system for gastric adenocarcinoma, 5 patients (11.9%) were in stage II(, 30 patients (71.4%) in stage III( and 7 patients (16.7%) in stage IIII(. The maximum tumor diameter was > 5 cm in 18 patients (42.9%). Borrmann type III(-IIII( was found in 29 patients (69.0%), and poorly differentiated (or undifferentiated) tumor was found in 32 patients (76.2%). Radical operations were performed in 31 patients (73.8%), the reasons of non radical operations included infiltration of pancreas in 3 patients, infiltration of radices mesocili transvers in 1 patient and classification of stage IIII( in 7 patients. Lymph node dissection was performed in 37 patients, 83.8% of them (31/37) was found with lymphatic metastases. Twenty-five patients received adjuvant chemotherapy except for 7 patients in stage IIII( and 10 patients who refused adjuvant chemotherapy. All the patients had an average survival time of 36.4 months and median survival time of 28.0 months, and the overall 1-, 3- and 5-year survival rates were 82.2%, 42.3% and 18.2% respectively. Univariate analysis revealed that tumor size (χ=4.039, P=0.044), Borrmann type (χ=18.728, P=0.000), tumor differentiation (χ=19.612, P=0.000), radical gastectomy (χ=41.452, P=0.000), lymph node metastasis (χ=9.689, P=0.002) and clinical stage (χ=26.277, P=0.000) were associated with postoperative survival. Multivariate analysis revealed that tumor differentiation (HR=10.560, 95%CI:2.263-49.281, P=0.003), radical gastrectomy (HR=4.309, 95%CI:1.311-14.168, P=0.016) and clinical stage (HR=2.392, 95%CI:1.022-5.600, P=0.044) were independent prognosis factors.

CONCLUSIONSPrimary gastric adenosquamous cell carcinoma is rare with poor prognosis. Radical gastrectomy is recommended. Tumor differentiation, radical gastrectomy and clinical stage are important indicators to evaluate prognosis of primary gastric adenosquamous cell carcinoma.

OBJECTIVE: To assess the outcome of the treatment of primary vaginal cancer using definitive radiotherapy (RT) and to evaluate the prognostic factors of survival. METHODS: The medical records of nine institutions were retrospectively reviewed to find the patients with vaginal cancer treated with definitive RT with or without chemotherapy. A total of 138 patients met the inclusion criteria. None had undergone curative excision. RESULTS: The median follow-up time of the survivors was 77.6 months and the median survival time was 46.9 months. The 5-year overall survival, cancer-specific survival (CSS), and progression-free survival (PFS) rates were 68%, 80%, and 68.7%, respectively. In the survival analysis, the multivariate analysis showed that a lower the International Federation of Gynecology and Obstetrics (FIGO) stage and prior hysterectomy were favorable prognostic factors of CSS, and a lower FIGO stage and diagnosed prior to year 2000 were favorable prognostic factors of PFS. In the subgroup analysis of the patients with available human papillomavirus (HPV) results (n=27), no statistically significant relationship between the HPV status and recurrence or survival was found. Grade 3 or 4 acute and late toxicity were present in 16 and 9 patients, respectively. The FIGO stage and the tumor size were predictors of severe late toxicity. CONCLUSION: The data clearly showed that a higher FIGO stage was correlated with a worse survival outcome and higher severe late toxicity. Therefore, precise RT and careful observation are crucial in advanced vaginal cancer. In this study, the HPV status was not related to the survival outcome, but its further investigation is needed.

Hypoxia-inducible factor-1 alpha (HIF-1α) plays a vital role in the initiation, evaluation and prognosis in lung cancer. The prognostic value of HIF-1α reported in diverse study remains disputable. Accordingly, a meta-analysis was implemented to further understand the prognostic role of HIF-1α in lung cancer. The relationship between HIF-1α and the clinicopathological characteristics and prognosis of lung cancer were investigated by a meta-analysis. PubMed and Embase were searched from their inception to January 2015 for observational studies. Fixed-effects or random-effects meta-analyses were used to calculate odds ratios and 95% confidence intervals of different comparisons. A total of 20 studies met the criteria. The results showed that HIF-1α expression in lung cancer tissues was significantly higher than that in normal lung tissues. Expression of HIF-1α in patients with squamous cell carcinoma was significantly higher than that of patients with adenocarcinomas. Similarly, non-small cell lung cancer (NSCLC) patients had higher HIF-1α expression than small cell lung cancer (SCLC) patients. Moreover, lymph node metastasized tissues had higher HIF-1α expression than non-lymph node metastasized tissues. A high level HIF-1α expression was well correlated with the expression of vascular endothelial growth factor and epidermal growth factor receptor in the NSCLC. Notably, NSCLC or SCLC patients with positive HIF-1α expression in tumor tissues had lower overall survival rate than patients with negative HIF-1α expression. It was suggested that HIF-1α expression may be a prognostic biomarker and a potential therapeutic target for lung cancer.

Bladder cancer remains a commonly diagnosed malignancy worldwide, bringing huge economic burden and high morbidity for patients. Assessment of prognostic significance of lymphovascular invasion (LVI) is a critical issue in the surgical management of bladder cancer after transurethral resection or radical cystectomy. A systematic search of PubMed, Embase and Cochrane Library was performed up to Oct 10, 2014 to identify eligible studies. Outcomes of interest were collected from studies comparing overall survival (OS), cancer specific survival (CSS) and recurrence free survival (RFS) in patients with the LVI. Results of studies were pooled, and combined hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) for survival were used as the effect size estimation. Funnel plots were done to show the publication bias, while the forest plots and subgroup analyses were used to limit the heterogeneity. A total of 20 studies (10 663 patients) met the eligibility criteria and were included for this meta-analysis. Our pooled results showed that there were significant differences in OS (pooled HR, 1.71; 95%CI, 1.52-1.92; P<0.00001), CSS (pooled HR, 2.25; 95% CI, 1.80-2.81; P<0.00001) and RFS (pooled HR, 1.91; 95% CI, 1.57-2.32; P<0.00001) between the patients with LVI and the patients without LVI. There were significant heterogeneities observed in the studies concerning the relationship between LVI and CSS, RFS. There was no clear evidence of publication bias. When tumor stage was beyond T3, LVI lost its predictive value for CSS and RFS. For the patients who had negative lymph nodes, LVI was still an adverse predictor. Our pooled results demonstrate that LVI indicates poor prognosis of patients with bladder cancer after surgical procedures, and it can be of particular importance in clinical practice. However, these results need to be further confirmed by more adequately designed prospective studies.

BACKGROUNDPelvic lymph node metastasis (LNM) is an important prognostic factor in cervical cancer. Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers. Analyses of the effects of the number of positive lymph nodes (LNs), unilateral versus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking. The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence.

METHODSWe performed a retrospective review of 296 patients diagnosed with Stage IA-IIB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People's Hospital from November 2004 to July 2013. Ten clinicopathological variables were evaluated as risk factors for pelvic LNM: Age at diagnosis, gravidity, clinical stage, histological grade, tumor diameter, lymph-vascular space involvement (LVSI), depth of cervical stromal invasion, uterine invasion, parametrial invasion, and neoadjuvant chemotherapy.

RESULTSThe incidence of pelvic LNM was 20.27% (60/296 cases). Pelvic LNM (P = 0.00) was significantly correlated with recurrence. Pelvic LNM (P = 0.00), the number of positive pelvic LNs (P = 0.04) and a single group versus multiple groups of pelvic LNM (P = 0.03) had a significant influence on survival. Multivariate analysis revealed that LVSI (P = 0.00), depth of cervical stromal invasion (P = 0.00) and parametrial invasion (P = 0.03) were independently associated with pelvic LNM.

CONCLUSIONSPatients with pelvic LNM had a higher recurrence rate and poor survival outcomes. Furthermore, more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive IA-IIB cervical squamous cell carcinoma. LVSI, parametrial invasion, and depth of cervical stromal invasion were identified as independent clinicopathological risk factors for pelvic LNM.

BACKGROUND/AIMS: The efficacy of surveillance for esophageal squamous cell neoplasia (ESCN) in patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. Our study aimed to provide clinical data concerning the necessity of surveillance for detecting early ESCN in patients with HNSCC. METHODS: We retrospectively reviewed the data from 714 patients who were pathologically confirmed as having HNSCC (n=236 oral cavity cancers, 137 oropharyngeal cancers, 87 hypopharyngeal cancers, and 254 laryngeal cancers). RESULTS: Of 714 patients, during a median follow-up of 31 months, 48 ESCNs (37 synchronous and 11 metachronous) were detected in 36 patients (5%). Fifteen synchronous lesions (40.3%) were early ESCN, whereas nine metachronous lesions (81.8%) were early ESCN. The 3-year survival rates of HNSCC only and HNSCC combined with ESCN were 71.2% and 48.2%, respectively (p<0.001). Among 36 patients with ESCN, the 3-year survival rates for early and advanced ESCN were 77.7% and 21.7%, respectively (p=0.01). In the multivariate analysis, alcohol consumption and hypopharyngeal cancer were significant factors associated with the development of ESCN. CONCLUSIONS: HNSCC patients with early ESCN were similar in prognosis with patients without ESCN, in contrast to patients with advanced ESCN. Therefore, surveillance for the early detection of ESCN in patients with HNSCC, especially in alcohol drinkers and those with hypopharyngeal cancer, is warranted.

PURPOSE: The chromophobe subtype of renal cell carcinoma (chRCC) has generally been associated with a better prognosis than the clear cell type; however, debate continues as to absolute prognosis as well as the significance of certain prognostic variables. We investigated the significance of pathologic stage and a recently proposed chromophobe tumor grading (CTG) scheme in predicting chRCC outcomes. MATERIALS AND METHODS: All available chRCCs were identified from our surgical pathology archives from 1987-2010. Original slides were reviewed to verify diagnoses and stage, and each case was graded following a novel chromophobe tumor grade system criteria. Disease status was obtained from a clinical outcome database, and cancer specific deaths and recurrences were recorded. RESULTS: Eighty-one cases of chRCC were identified, and 73 had adequate follow-up information available. There were only 3 instances of cancer related recurrence or mortality, which included 1 disease specific mortality and 2 disease recurrences. Pathologic stage and CTG 3 were found to be significantly associated with the recurrences or death from chRCC, but there was no association with CTG 1 and CTG 2. CONCLUSIONS: chRCC is associated with a very low rate of cancer specific events (4.1%) even at a tertiary referral center. In our study, pathologic stage and CTG 3, but not CTG 1 or 2, were significantly associated with the development of these events.

Thrombocytosis and coagulation systems activation are commonly associated with disease progression and are suggested poor prognostic factors in patients with malignancies. This study aimed to investigate the prevalence and prognostic significance of thrombocytosis and elevated fibrinogen levels in patients with advanced non-small cell lung cancer (NSCLC). Initial platelet counts and fibrinogen levels were reviewed in 854 patients with histologically proven NSCLC. Thrombocytosis was defined as platelet counts > 450 x 10(9)/L. A serum fibrinogen level > 4.5 g/L was considered high. At the time of diagnosis, initial platelet counts and serum fibrinogen levels were evaluated before treatment. Clinicopathologic data including histological type, tumor, node, metastasis (TNM) stage, performance status, treatment method, and survival time were evaluated. Initial thrombocytosis was found in 6.9% of patients, and elevated fibrinogen levels were found in 55.1% of patients. Patients with thrombocytosis had a significantly poorer prognosis than patients with normal platelet counts (P < 0.001). In multivariate survival analysis, thrombocytosis was an independent prognostic factor (P < 0.001). An elevated serum fibrinogen level was associated with poor prognosis (P < 0.001). In conclusion, initial thrombocytosis and a high fibrinogen level are independent factors for predicting poor prognosis in patients with advanced NSCLC.
