Background: The clinical course of the neoplasm may vary due to both patient and tumor cell characteristics. Aim: The aim of this study was to research the influence of certain clinical and pathological features on the prognosis of early stage breast cancer. Materials and Methods: This study included 117 women that were treated and followed-up in between the years 2001-2011. The demographic, clinical and histopathological features of the cases were reviewed retrospectively. Statistical analysis: In categorical comparisons between groups, cross-tab statistics were provided and significance levels were estimated using chi-square test. Cox regression analysis, Pearson and Spearman correlation tests, and the Kaplan-Meier test were also used. Results: With an average of 35-months follow-up, the mean disease-free survival of patients was 91 months and the mean overall survival time was 132 months. In the whole study group, the disease-free survival rates were 88, 84, 83 and 52%, while the overall survival rates 95, 94, 83, and 83% within the first, third, fifth and tenth years, respectively. The disease-free and overall survival rates were decreased with increasing tumor grades, though this was not statistically significant. The presence of lymphovascular invasion, positive staining with Ki67 and postmenopausal status were associated with shorter disease-free and overall survival times. In multivariate analysis, only age and Her2/neu receptor status influenced the prognosis significantly. Conclusions: In parallel to clinical, histopathological, and immunohistochemical prognostic features in breast cancer, in this study positive Her2/neu receptor status, a previously accepted poor prognostic factor, was found to have positive influence after trastuzumab treatment.

배 경 : 위암은 세계적으로 암으로 인한 사망의 가장 많은 원인 중 하나이다. 위암 환자들은 진단시 자주 원격전이를 나타내고, 아직까지 수술이나 전이와 재발을 막기 위한 화학요법 후의 표준화된 요법은 없다. 목 적 : 연구 목적은 ‘수레바퀴 암치료법(WBT)’으로 치료받은 환자들에 있어서의 전체생존율과 무병생존율을 WBT 단독 혹은 기존 통상요법과 병용치료한 환자들을 비교하고 두 그룹의 생존율에 있어 유의성이 있는지를 관찰하는 것이다. 세팅과 디자인 : 대전대학교 둔산한방병원 동서암센터; 후향적 연구. 자료와 방법 : WBT를 시행하기 2개월 이전까지 수술이나 화학요법을 받은(혹은 어떠한 통상치료도 받지 않은) III기(40명)와 IV기(22명)의 62명의 위암 환자들을 후향적으로 분석했다. 환자들은 전이와 재발을 방지하는 PSM 캡슐, OnePlus 시럽, 항암단과 같이 한약을 포함한 WBT 계획을 따랐다. 전체생존율과 무병생존율을 분석했으며 환자들은 III기와 IV기 각각 89.55주와 49.27주(평균치) 동안 치료를 받았다. 통계분석 : 전체생존율과 무병생존율은 Kaplan-Meier법으로 측정하고 WBT 단독 및 병행 치료는 log rank test로 비교했다. 결 과 : III기에서 3년 전체생존율은 78.5%이고, 무병생존율은 78.3%였다. 40명 중 13명의 환자(32.5%)에게 전이와 재발이 있었다. IV기에서 2년 전체생존율은 18.2%이고, 무병생존율은 또한 18.2%였다. 22명 중 19명(86.4%)에게서 전이와 재발이 있었다. WBT 단독 및 병행치료법 중 병행치료의 효과가 높게 나타났지만 통계적으로 유의한 차이를 보이지는 않았다(전체생존율 p=0.5093, 무병사망율 p=0.5175 ). 결 론 : WBT는 위암 환자들에게 생존기간을 늘이고 전이를 방지하는 만족할 만한 결과를 산출했다. WBT의 주된 치료법은 한약(항암단, PSM 캡슐, OnePlus 시럽)으로 구성되어 있으며 향후에는 무작위의 전향적인 연구가 이 치료법만을 이용해서 수행되어야 할 것이다.

Background: The Ewing's sarcoma family is a group of small round cell tumors which accounts for 10-15% of all primary bone neoplasms. The aim of this study was to evaluate the survival of Ewing's sarcoma patients in our province and to determine of influencing factors. Materials and Methods: All patients with documented Ewing's sarcoma/primitive neuroectodermal tumor(PNET) family pathology were enrolled in this study during a period of eight years. For all of them local and systemic therapy were carried out. Overall and event free survival and prognostic factors were evaluated. Results: Thirty two patients were enrolled in the study. The median age was 17.5 years. Twenty (65.2%) were male and 9 (28.1%) were aged 14 years or less. Mean disease free survival was 26.8 (95%CI; 13.8-39.9) months and five year disease free survival was 26%. Mean overall survival was 38.7 months (95%CI; 25.9-50.6) and median overall survival was 24 months. Five year overall survival was 25%. From the variables evaluated, only presence of metastatic disease at presentation (p value=0. 028) and complete response (p value =0. 006) had significant relations to overall survival. Conclusions: Survival of Ewing's sarcoma in our province is disappointing. It seems to be mostly due to less effective treatment. Administration of adequate chemotherapy dosage, resection of tumor with negative margins and precise assessment of irradiation volume may prove helpful.

Background and Aim: Breast cancer is a major healthcare problem in women. There are many reports about up-regulation of Hsp27 in cancer tissues but less is known about the potential relationship between Hsp27 antibody levels and breast cancer complications. We here investigated concentrations of serum Hsp27 antigen and antibodies in subjects with and without breast cancer and assessed potential associations with two-year disease-free survival, histological grade and number of lymph nodes. Materials and Methods: Specifically, serum Hsp27 antigen and antibody levels from 97 patients with breast cancer, and 65 healthy controls were determined by enzyme-linkedimmunosorbent assays (ELISAs). Results: Serum Hsp27 and antibody levels were significantly (p<0.001) higher in patients with breast cancer compared to the control group, but no relationship were found with two-year disease free survival, histological grade or number of lymph nodes (p> 0.6, 0.2 and 0.9 respectively). Conclusions: Elevated levels of Hsp27 antibody occur with women with breast cancer but do not appear to be associated with the presence of disease clinical complications.

Purpose: Anemia is associated with poor treatment results for a variety of cancers. The effect of low hemoglobin levels on long-term outcomes after the treatment of patients with an anal squamous cell carcinoma (SCC) remains unclear. For that reason, this study aimed to investigate the effect of anemia on treatment outcomes following chemoradiation for an anal SCC. Methods: This was a retrospective study of all patients who underwent curative treatment for an anal SCC between 2009 and 2015 at 2 trusts in the United Kingdom. Data were collated from prospectively collected cancer databases and were cross-checked with operating-room records and records in the hospitals' patient management systems. Results: We identified 103 patients with a median age of 63 years (range, 36-84 years). The median overall survival was 39 months (range, 9-90 months), and the disease-free survival was 36 months (range, 2-90 months). During the follow-up period, 16.5% patients died and 13.6% patients developed recurrence. Twenty-two people were anemic prior to treatment, with a female preponderance (20 of 22). No differences in disease-free survival (P = 0.74) and overall survival (P = 0.12) were noted between patients with anemia and those with normal hemoglobin levels. On regression the analysis, the combination of anemia, the presence of a defunctioning colostomy, lymph-node involvement and higher tumor stage correlated with poor overall survival. Conclusion: In this study, anemia did not influence disease-free survival or overall survival. We suggest that the interaction between anemia and survival is more complex than previously demonstrated and potentially reliant on other coexisting factors.

Background: Primary hepatic neuroendocrine carcinoma (PHNEC) is rarer than extrahepatic gastrointestinal neuroendocrine carcinoma (NEC). It is difficult to make a correct diagnosis and poses a challenge for management. Materials and Methods: Ten PHNEC patients were admitted to our hospital from June 2006 to June 2011. Laboratory tests and imaging scans were performed for diagnosis and exclusion of extrahepatic NEC. All patients were AFP - and CA199-. Seven patients had solid tumors with cystic changes on ultrasonography, CT and/or MRI. For the initial treatment, four patients received combined-therapy and six monotherapy. Considering overall treatment, six patients received combined-therapy and four patients monotherapy. Staging criteria of primary hepatocellular carcinoma (PHC, AJCC 7th edition) were used to differentiate the stage of all patients: 3 patients were stage I, 2 stageII, 4 patients stageIII and 1 stageIV. All patients were followed up and clinical data were gathered. Results: The median follow-up duration was 38.5 months. The 1-year, 2-year, 3-year and 6-year disease-free survival was 80.0%, 46.2% and 46.2% and 0% respectively. The overall survival rates were 100%, 67.1%, 67.1% and 33.6% respectively. Patients in early-stages (I/II) had similar disease-free and overall survival as those in advanced-stages (III/IV). Patients with monotherapy had significant shorter disease-free and overall survival than the patients with combination-therapy. Conclusions: PHNEC has a unique specificity during its occurrence and development. The staging criteria of PHC might not be suitable for the PHENT. More convenient and effective features need to be found in imaging and laboratory detection. Surgical resection, TACE, chemotherapy and radiofrequency ablation should be performed in combination and actively for patients with PHNEC or recurrence to get the best effectiveness; they might extend the disease-free and overall survival.

To determine the efficacy of postoperative adjuvant chemotherapy with paclitaxel plus cisplatin (Taxol + DDP, TP therapy) for stage IIA esophageal squamous cell carcinoma (ESCC) and to investigate the expression of RUNX3 in lymph node metastasis-negative esophageal cancer and its relationship with medical prognosis, a retrospective summary of clinical treatment of 143 cases of stage IIA esophageal squamous cell carcinoma patients was made. The patients were divided into two groups, a surgery alone control group (52 patients) and a chemotherapy group that received postoperative TP therapy (91 patients). The disease-free and 5 year survival rates were compared between the groups and a multivariate analysis of prognostic factors was performed. The same analysis was performed for cases classified as RUNX3 positive and negative, with post-operative specimens assessed by immunohistochemistry. Although the disease-free and 5 year survival rates in control and chemotherapy groups did not significantly differ and there was no significance in RUNX3 negative cases, postoperative adjuvant chemotherapy in the chemotherapy group was shown to improve disease-free and 5 year survival rate compared to the control group in RUNX3 positive cases. On Cox regression multivariate analysis, postoperative adjuvant chemotherapy (P<0.01) was an independent prognostic factor for RUNX3 positive cases, suggesting that postoperative TP may be effective as adjuvant chemotherapy for stage IIA esophageal cancer patients with RUNX3 positive lesions.

Oral squamous cell carcinoma (OSCC) is predominantly a disease of middle-aged men with long-term exposure to tobacco and alcohol. An increasing trend has been reported at a younger age worldwide. Clinical records of 100 patients under the age of 45 years treated specifically for oral cavity SCC in our hospital during a 10-year period were retrospectively analyzed to calculate the survival rates. An obvious male predominance coincided with smoking trend among Chinese young individuals and female patients were more likely to have no traditional risk factors such as smoking or drinking. The 5-year overall survival rate and disease-free survival rate were 61.0% and 75.5%, respectively, consistent with other published series over the decade showing a relatively better survival among the young. No significant differences clearly correlated with outcome when comparing non-smokers non-drinkers to ever-smokers and ever drinkers (P>0.05). Overall survival rate and disease free survival rate was found to be significantly higher in patients with early-stage disease than with advanced stage disease (P=0.001, P=0.009 respectively). The strong influence of clinical stage on prognosis emphasizes the importance of early diagnosis and treatment of oral malignancies for this unique clinical subgroup.

Background: It has been demonstrated that neutrophil:lymphocyte (NLR) and platelet:lymphocyte (PLR) ratios are associated with prognosis in cancer patients. The aim of this study was to investigate whether pretreatment white blood cell (WBC), neutrophil, lymphocyte, monocyte, platelet, basophil and eosinophil counts, LDH level, NLR and PLR are associated with prognosis in patients with malignant pleural mesothelioma (MPM). Materials and Methods: We retrospectively reviewed files of 50 patients who were managed with a diagnosis of MPM between 2005 and 2010. Demographic and clinical characteristics, treatments, response to treatment and prognostic factors were evaluated, along with relationships between pretreatment blood parameters and prognosis. Results: Overall, 38 men and 12 women were included to the study. Mean age was $61.5{\pm}9.4$ years (range: 39-83 years). There was advanced disease in 86% (n=43) and the histological type was epithelial mesothelioma in the majority (82%). Of the cases, 17 (34%) received radiotherapy, while 42 cases underwent first- and second-line chemotherapy, with cisplatin plus pemetrexed as the most commonly used regimen. In the assessment after therapy, it was found that there was complete response in 4 cases (8%), partial response in 10 cases (20%), stable disease in 17 cases (34%) and progression in 19 cases (38%). Median follow-up was 10 months (range: 10 day-30 months). Median overall survival was found to be 20.7 months while median progression-free survival as 10 months. In univariate and multivariate analyses, it was found that factors significantly affecting overall survival included stage (p=0.030), response to treatment (p=0.026) and monocyte count (p=0.004), while factors affecting disease-free survival included NLR (p=0.018), response to treatment (p=0.001), and PLR score (p=0.003). Conclusions: Overall and disease-free survival was found to be better in cases with a WBC count<8.000, platelet count<300,000, and low NLR and PLR scores in malignant pleural mesothelioma.
