Background: The aim of this study was to investigate the relationship of body mass index with overall and progression-free survival as well as other prognostic factors of breast cancer in patients with non-metastatic breast cancer. Materials and Methods: We retrospectively reviewed 456 patients diagnosed with breast cancer in the Radiation Oncology department of Kayseri Teaching Hospital between 2005 and 2013. We investigated relationship of body mass index with prognosis and other prognostic factors. Results: The study included 456 patients (447 women and 9 men). Mean age at presentation was 55.6 years. Of the cases, 96.9% underwent modified radical mastectomy and 95.0% received chemotherapy, while 82.4% received radiotherapy and 60.0% were given hormone therapy. Body mass index was >25 mg/kg2 in 343 cases. Five- and 10-years overall survival rates were 77% and 58% whereas progression-free survival rates were 65% and 49%, respectively. In univariate analyses, factors including stage (p=0.046), tumor diameter (p=0.001), lymph node metastasis (p=0.006) and body mass index (p=0.030) were found to be significantly associated with overall survival, while perinodal involvement was found to be significantly associated with progression-free survival (p=0.018). In multivariate analysis, stage (p=0.032; OR: 3.8; 95% CI: 1.1-13), tumor diameter (p<0.000; OR: 0.0; 95% CI: 0.0-0.3), lymph node metastasis (p=0.005; OR: 0.0; 95% CI: 0.0-0.5) and BMI (p=0.027; OR: 0.02; 95% CI: 0.0-0.8) remained as significantly associated with OS. Conclusions: In our study, it was seen that overall survival time was shorter in underweight and obese patients when compared to normal weight patients.

With the widespread use of the obstetrical ultrasound, identification of a fetal suprarenal mass becomes more common. Most of these masses prove to be congenital neuroblastomas (CNB) postnatally. However, the diagnosis is often confused with other benign lesions and the post-natal management remains controversial. The medical records of 13 patients that underwent primary surgical excision for an antenatally detected adrenal CNB, between January 1995 and April 2009, were reviewed retrospectively. The clinical, radiological, surgical, and pathological data on the suprarenal mass were collected. Staging evaluation was performed after histological confirmation of the CNB. Most of the CNBs were stage I (N=11), with 1 stage IV and 1 stage IV-S. Four patients (3 stage I and 1 stage IV-S) had N-myc gene amplification. The stage I patients were cured by surgery alone, and stage IV patients underwent 9 cycles of adjuvant chemotherapy and currently have no evidence of disease after 39 months of follow-up. The patient with stage IV-S is currently receiving chemotherapy. There were no post-operative complications. For early diagnosis and treatment, surgical excision should be considered as the primary therapy for an adrenal CNB detected before birth. The surgery can be safely performed during the neonatal period and provides a cure in most cases. Surgical diagnosis and treatment of CNB is recommended in neonatal period.

Purpose: This study was designed to explore quality of life (QOL) in patients with stomach cancer by using the World Health Organization Quality of Life (WHOQOL) Instrument- Korean version. Materials and Methods: Thirty-one (31) patients with stomach cancer after curative resection were recruited with informed consent. Age- and gender-matched hospital staff served as controls. The 100-item WHOQOL Instrument, including physical domain, psychological domain, social domain, independence domain, environment domain, and spiritual domain, was employed for the all subjects. Results: In patients with stomach cancer after operation, only two domains, physical and independence, were associated with worse quality of life. In those domains, patients with advanced stage, with total gastrectomy, with adjuvant chemotherapy, and early or late postoperative period ($\leqq$2 years or >5 years after operation), could be perceived of having a worse quality of life. Conclusion: Not only scientific objective success but also individual subjective perception of condition could be important for managing patients with stomach carcinomas after curative resection. In this context, the WHOQOL reflecting multi-dimensional state of well being could be a useful tool across a variety of cultural and value systems in the world.

Purpose: To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. Materials and Methods: Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. Results: The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; P = 0.038), lymph node dissection extent (HR, 0.201; P = 0.002). and maintenance oral chemotherapy (HR, 2.964; P = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). Conclusion: The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

Purpose: To study the overall treatment time (OTT) and acute toxicity of intensity-modulated radiotherapy (IMRT) treatment for nasopharyngeal carcinoma (NPC). Methods: This retrospective study covered all NPC patients who underwent radical IMRT treatment at the Penang General Hospital from June 2011 to February 2012. Patients of any age and stage of disease with histologically proven diagnosis were included. Information was collected on patient demographics, clinical stage, treatment received, including any neoadjuvant and/or concurrent chemotherapy, acute toxity and completion of IMRT within the OTT. Results: A total of 26 NPC patients were treated with IMRT during the study period; 88.5% had stage III/IV disease. 45.2% received neo-adjuvant chemotherapy while 50.0% were given concurrent chemo-irradiation. All patients completed the treatment and 92.3% within the 7 weeks OTT. Xerostomia was present in all patients with 92.3% having grade 2. Severe grade III/IV acute toxicity occurred in 73.1% of patients, the commonest of which was oral mucositis (57.6%). This was followed by dysphagia which occurred in 53.8%, skin reactions in 42.3% and weight loss in 19.2%. However, haematological toxicity was mild with only one patient having leucopaenia. Conclusion: IMRT treatment for NPC is feasible in our center. More importantly, it can be delivered within the 7 weeks OTT in the majority of patients. Severe grade 3/4 toxicity is very common (73.1%) and thus maximal nutritional and analgesic support is required throughout the treatment.

Background: Survival rates after resection of advanced gastric cancer are extremely poor. An increasing number of patients with gastric carcinomas (GC) are therefore being treated with preoperative chemotherapy. We evaluated 36 month survival rate of GC patients that were treated by adding a neoadjuvant chemoradiotherapy before gastrostomy.Materials and Methods: Patients with stage II or III gastric adenocarcinomas were enrolled. The patients divided into two groups: (A) Neoadjuvant group that received concurrent chemoradiation before surgery (4500cGy of radiation at 180cGy per day plus chemotherapy with cisplatin and 5-fluorouracil, in the first and the end four days of radiotherapy). Resection was attempted 5 to 6 weeks after end of chemoradiotherapy. (B) Adjuvant group that received concurrent chemo-radiation after surgical resection. Results: Two (16.7%) patients out of 12 patients treated with neoadjuvant chemo-radiotherapy and 5 (38.5%) out of 13 in the surgery group survived after 36 months. These rates were not significantly different with per protocol and intention-to-treat analysis. The median survival time of patients in group A and B were 13.4 and 21.6 months, respectively, again not significantly different. Survival was significantly greater in patients with well differentiated adenocarcinoma in group B than in group A (p<0.004). Conclusions: According to this study we suggest surgery then chemoradiotherapy for patients with well differentiated gastric adenocarcinoma rather than other approaches. Additional studies with greater sample size and accurate matching relying on cancer molecular behavior are recommended.

Background: The purpose of this study was to determine the clinical characteristics, patterns of recurrence and survival outcomes in patients with uterine carcinosarcomas treated in our institution. Materials and Methods: Records of 26 patients diagnosed between 2007 and 2011 with uterine carcinosarcoma were retrospectively evaluated for demographic features, tumor characteristics, treatment regimens and patient outcomes in terms of DFS and OS Results: Median age was 61 (range 43-78). 10 patients (38%) had stage I disease at diagnosis, 3 (12%) had stage II, 4 (15%) had stage III and 9 (35%) had stage IV. Sixteen patients (62%) received chemotherapy with paclitaxel and carboplatin for 6 cycles. One patient underwent radiotherapy. Median follow up was 17 months. Sixteen patients relapsed and 13 died during follow up. Considering recurrence, 5 out of 16 patients had lung metastases, one had brain metastases and 9 had only intraabdominal recurrence. The 3 year DFS was 37% and the 3 year OS was 30%. Conclusions: Our data show that uterine carcinosarcomas tend to be at advanced stage at diagnosis and despite the use of chemotherapy, overall prognosis is poor. Surgery remains the mainstay of treatment. More effective adjuvant strategies are needed to reduce relapse and death rates.

Background: When managing patients who require repeated venous access, gaining a viable intravenous route has been problematic. To improve the situation, various studies on techniques for venous access have been conducted. The aim of this study is to evaluate the clinical results of complications following totally implanted central venous access port (TICVAP) insertion. Methods: A retrospective analysis was conducted on 163 patients, from December 2008 to March 2013. The occurrence of complications was studied in three separate periods of catheter use: the intraoperative period, postoperative period, and period during the treatment. Results: A total of 165 cases of TICVAP insertions involving 156 patients were included in the final analysis. There were 35 complications (21%) overall. Among these, 31 cases of complications (19%) occurred during the treatment period and the other 4 cases were intraoperative and postoperative complications (2%). There were no statistically significant differences in age and gender of the patients between the two groups to be risk factors (p=0.147, p=0.08). Past history of chemotherapy, initial laboratory findings, and the locations of TICVAP insertion also showed no statistical significance as risk factors (p>0.05). Conclusion: Because the majority of complications occurred after port placement and during treatment, meticulous care and management and appropriate education are necessary when using TICVAPs.

Purpose: To evaluate the necessity of regional nodal irradiation (RNI) for pT1-2N1 breast cancer patients treated with breast-conserving surgery and radiotherapy, we compared clinical outcomes of patients treated with and without RNI. Materials and Methods: We retrospectively analyzed the data of 214 pT1-2N1 breast cancer patients treated with breast-conserving surgery and whole breast irradiation from 2007-2016. There were 142 (66.4%), 51 (23.85%), and 21 (9.8%) patients with one, two, and three positive lymph nodes, respectively. Thirty-six patients (16.8%) underwent RNI. Adjuvant chemotherapy, endocrine therapy, and anti-HER2 therapy were given to 91.6%, 79.0%, and 15.0% patients, respectively. The most common chemotherapy regimen was anthracycline + cyclophosphamide, followed by taxane (76.5%). The median follow-up was 64 months (range, 6 to 147 months). Patients were propensity matched 1:2 into RNI and no-RNI groups. Results: Two patients experienced locoregional recurrences simultaneously with distant metastases, ten patients developed distant metastases, and one patient died. Before matching, the 5-year actuarial locoregional control (LRC), distant metastasis-free survival (DMFS), and overall survival (OS) rates in the RNI and no-RNI groups were 100.0% and 99.4% (p = 0.629), 94.1% and 96.0% (p = 0.676), and 100.0% and 99.4% (p = 0.658), respectively. After matching, the 5-year LRC, DMFS, and OS were 98.3% and 100.0% (p = 0.455), 96.6% and 93.9% (p = 0.557), and 100.0% and 100.0% (p > 0.999) in the RNI and no-RNI groups, respectively. No clinicopathologic or treatment-related factors were significantly associated with LRC, DMFS, or OS. Conclusion: Adding RNI did not show superior LRC, DMFS, or OS in pT1-2N1 breast cancer patients.
