Background: Soft tissue sarcomas (STS) are a heterogeneous group of tumors, and approximately 40-50% of patients with STS develop metastatic disease. The median overall survival of those patients was 12 months and their 5-year survival rate was 8%. Therefore, study on more effective treatment, especially the targeting therapies, is urgently needed. Objective: To evaluate the efficacy and safety of Endostar$^{(R)}$ combined with chemotherapy in patients with advanced STS. Methods: A retrospective case-series study was conducted in Cancer Institute of PLA, Xinqiao Hospital. A total of 71 patients suffering from advanced STS (IIB - IV) were included, of whom 49 cases treated with chemotherapy alone were defined as the control group and the rest 22 cases treated with the traditional chemotherapy combined with Endostar$^{(R)}$ were defined as the test group. The short-term therapeutic effects including objective response rate (ORR), disease control rate (DCR) and safety were evaluated in the two groups. In the follow-up, progression-free survival (PFS) and overall survival (OS) were also observed. Results: In the test and control groups, the ORR was 18.2% and 12.2%, respectively (P=0.767), and the DCR was 86.4% and 61.2%, respectively (P=0.034). The median time to progression in the test and control groups was 120 days and 70 days with significant difference (P = 0.017), while the median overall survival was 452 days and 286 days without significant difference (P=0.503). The one-year survival rate in the test group and control group was 56.2% and 35.4%, respectively, while the two-year survival rate was 30.2% and 26.5%, respectively. No significant difference in the side effects was found between the two groups. Conclusions: Endostar$^{(R)}$ combined with chemotherapy resulted in a higher DCR and longer PFS in the patients with advanced STS, and the toxicity was tolerable.
Purpose: To assess the chronological changes of disease-related kyphosis after chemotherapy alone. Materials and Methods: A total of 101 children aged 2 to 15 years with spinal tuberculosis, accompanied by various stages of disease processes were enrolled for analysis. By utilizing the images in them, the growth plate condition and chronological changes of kyphosis after chemotherapy were analyzed at two points in time; the first assessment was at post-chemotherapy one-year and second at the final discharge. Results: Complete disc destruction in the cervical, dorsal and lumbosacral spines was observed in 2 out of 40 children (5.0%), 8 out of 30 children (26.7%), and 6 out of 31 children (19.4%), respectively. In those cases, the residual kyphosis inevitably developed. In the remaining children, the discs were intact or partially damaged. Among the 101 children kyphotic deformity was maintained without change in 20 children (19.8%). Kyphosis decreased in 14 children (13.9%), while it increased in 67 children (66.3%) with non-recoverably damaged growth plate. Conclusion: Although it is tentatively possible to predict the deformity progress or non-progress and spontaneous correction at the time of the initial treatment, its predictive accuracy is low. Therefore, assessment of the chronological changes should be performed at the end of chemotherapy. In children with progressive curve change, assessment of deformity should be continued until maturity.
Objectives: To study the clinical features of the primary nasal/nasopharyngeal non-Hodgkin's lymphomas and to evaluate the implication of immunophenotyping as a prognostic factor. Patients and Methods: From January 1990 to December 1997,41 patients(median age, 41 years) of primary nasal/nasopharyngeal non-Hodgkin's lymphoma were studied. The clinical records and paraffin-embedded tissue blocks were reviewed retrospectively. The histologic features, immunophenotypic findings(pan-T, pan-B, CD3, CD56) and Epstein-Barr virus in situ hybridizatios were examined. The prognostic factors for clinical outcome were evaluated in these patients. According to Ann-Arbor system, there were 30 patiets(73%) with stage IE, 4(10%) with stage IIE, 3(7%) with stage IIIE, 4(10%) with stage IVE lymphoma. Among the patients with stage IE/IIE, 4 patients received local radiation alone, 4 received chemotherapy alone, 25 received combination chemotherapy and radiotherapy and 1 refused treatment. The patients with stage IIIE/IVE were given combination chemotherapy and radiotherapy. Results: Immunophenotyping were performed in 40 patients and staining results were as follows: 3(7%) patients with B cell, 17(42%) with T cell, 18(44%) with NK/T cell(CD56 positive), and two patients with unclassifiable result. Epstein-Barr(EB) virus in situ hybridization were performed in 28 patients and 23(82%) patients had positive EBV-encoded RNAs(EBERs). 21(55%) patients achieved a complete remission. There was no difference in complete remission between radiation alone and combination therapy. With median follow-up of 30 months, 5-years disease free survival of complete responders was 60% and 5-years overall survival rate was 36%. Multivariate analysis showed that better overall survival was related with absence of B symptoms, ECOG performance${\leq}1$ and non-NK cells. Conclusion: Most of all cases were positive for EBER. Since NK/T phenotype carried the worst prognosis, analysis for CD56 expression should be done. Further prospective studies were warranted to evaluate the role of chemotherapy in stage IE/IIE.

Purpose : To clarify the clinical benefit derived from the combined modality therapy (CMT) consisting of chemotherapy (CT) and involved field radiotherapy (RT) for stage I and II angiocentric lymphomas of the head and neck. Materials and Methods : Of 143 patients with angiocentric lymphoma of the head and neck treated at our hospital between 1976 and 1995, 104 patients (RT group) received involved field RT alone with a median dose of 50.4 Gy (range : 20~70 Gy), while 39 patients (CMT group) received a median 3 cycles (range : 1~6 cycles) of CT before involved field RT. The response rate, patterns of failure, complications, and survival data of the RT group were compared with those of the CMT group. Results : Despite a higher response rate, local failure was the most common pattern of failure in patients of both groups. The patterns of failure, including the systemic relapse rate were not influenced by the addition of combination CT. Although both modalities were well tolerated by the majority of patients, aberrant immunologic disorders or medical illnesses, such as a hemophagocytic syndrome, sepsis, intractable hemorrhage, or the evolution of second primary malignancies were more frequently observed in patients of the CMT group. The prognosis of patients in the RT group was relatively poor, with a 5-year overall actuarial survival rate of 38% and disease-free survival rate of 32%, respectively. However, their clinical outcome was not altered by the addition of systemic CT. Achieving complete remission was the most important prognostic factor by univariate and multivariate analyses, but treatment modality was not found to be a prognostic variable influencing survival. Conclusions : Involved field RT alone for angiocentric lymphoma of the head and neck was insufficient to achieve an improved survival rate, but the addition of CT to involved field RT failed to demonstrate any therapeutic advantage over involved field RT alone.

Purpose : To evaluate the role of combination therapy of external radio-therapy and chemotherapy in the management of advanced esophageal cancer as a primary treatment compared with radiation therapy alone. Materials and Methods : A retrospective review of evaluable 55 esophageal cancer patients referred to the Department of Therapeutic Radiology, Paik Hospital for the external radiotherapy between Jul, 1983 and Dec. 1994 was undertaken. Combined therapy patients (A group) were 30 and radiation alone patients (B group) were 25. Median age was 60 years old in A group (ranges : 42-81) and 65 years old in B group (ranges : 50-81). The male patients were 53. The fifty patients had squamous cell carcinomas. Radiation doses of 2520-6480c0y were delivered over a period of 4-7weeks, using 4MV LINAC. Chemotherapy was administered in bolus injection before, after, or during the course of external radiotherapy. The local control rate and patterns of failure according to both treatment modalities and 1, 2 year survival rates according to prognostic factors (stage, tumor length, radiation dose etc.) were analysed. Resuts : Median follow up Period was 7 months (range : 2-73 months). Median survival was 7.5 months (20 days-29 months) in A group and 5 months (20 days-73 months) in B group. The 1, 2 YSRs were $26.7\%$, $8.9\%$ in A group, $12.7\%$, $4.3\%$ in B group (p>0.05), respectively. The 1, 2 YSRs according to stage(II/III), tumor length (5cm more or less). radiation dose (5000cGymore or less) of A and B group were analyzed and the differences of survival rates of both treatments were not statistically significant. But among group B, patients who received 5000cGy or more showed significant survival benefits (p<0.05). The treatment response rates of A and B group were $43.8\%$. $25.0\%$, respectively. Complete response rate of $25.0\%$ in A and $8.3\%$ in B were achieved. The local failure and distant metastsis were $52.4\%$. $23.8\%$ in A group, $64.3\%$, $14.3\%$ in 8 group, respectively. The combination therapy revealed more frequent leukopenia and nausea/vomiting than radiation alone group, but degree of side effects was only mild to moderate. Conclusion : The combined external radiotherapy and chemotherapy for advanced esophageal cancer appears to improve the response rate, local control rate and survival rate, but the improvement was not statistically significant. The side effects of combined modalities were mild to moderate without significant morbidity. Therefore it may be worthwhile to continue the present combined external radiotherapy and chemotherapy in the management of advanced esophageal cancer to confirm our result.
Purpose: To evaluate whether combined transarterial chemoembolization (TACE) with radiofrequency ablation (RFA) or percutaneous ethanol injection (PEI) for hepatocellular carcinoma (HCC) have superior efficacy to transarterial chemoembolization (TACE) alone a retrospective review was conducted. Methods: During January 2009 to March 2013, 108 patients with hepatocellular carcinoma underwent TACE or combined therapies (TACE+RFA or TACE+PEI). The long-term survival rates were evaluated in those patients by various statistical analyses. Results: The cumulative survival rates in the combined TACE+RFA/PEI group were significantly superior to those in the TACE alone group. When the comparison among the groups was restricted to patients with two or three tumors fulfilling the Milan criteria, significantly greater prolongation of survival was observed in the combined TACE+ RFA/PEI group than in the RFA/PEI alone group. Conclusions: In terms of the effect on the survival period, combined TACE+ RFA/PEI therapy was more effective than TACE monotherapy, and also more effective than PEI or RFA monotherapy in cases with multiple tumors.

Objective: Women with cervical cancer (CC) found to have positive surgical margins, positive lymph nodes, and/or parametrial invasion receive a survival benefit from postoperative chemoradiotherapy (CRT) vs. radiation therapy (RT) alone. However, older women may not benefit to the same extent, as they are at increased risk of death from non-oncologic causes as well as toxicities from oncologic treatments. This study sought to evaluate whether there was a survival benefit of CRT over RT in elderly patients with cervical cancer. Methods: The National Cancer Database was queried for patients ${\geq}70$ years old with newly diagnosed IA2, IB, or IIA CC and positive margins, parametrial invasion, and/or positive nodes on surgical resection. Statistics included logistic regression, Kaplan-Meier overall survival (OS), and Cox proportional hazards modeling analyses. Results: Altogether, 166 patients met inclusion criteria; 62 (37%) underwent postoperative RT and 104 (63%) underwent postoperative CRT. Younger patients and those living in areas of higher income were less likely to receive CRT, while parametrial invasion and nodal involvement were associated with an increased likelihood (p<0.05 for all). There were no OS differences by treatment type. Subgroup analysis by number of risk factors, as well as each of the 3 risk factors separately, also did not reveal any OS differences between cohorts. Conclusion: In the largest such study to date, older women with postoperative risk factor(s) receiving RT alone experienced similar survival as those undergoing CRT. Although causation is not implied, careful patient selection is paramount to balance treatment-related toxicity risks with theoretical outcome benefits.
Purpose: This analysis was to compare the result of radiation alone and chemoradiation in cervical cancer in terms of response, survival, failure, and complication. Materials and Methods: A retrospective analysis of 135 cervical cancer patients treated with definitive radiotherapy from November 1985 to December 1991 was performed. Fifty-six patients were treated with radiation alone and 79 patients were treated with cisplatin-based chemotherapy plus radiation. Follow-up period ranged from 5 to 105 months with a median 47 months. According to the FIGO classification, the patients were subdivided into 18 $(13.3\%)$ stage IB, 7 $(5.2\%)$ stage IIA, 97 $(71.9\%)$ stage IIB, and 9 $(6.7\%)$ stage IIIB. Results: A complete response was noted in 51 patients $(91.1\%)$ of the radiation alone group, and 68 patients $(86.1\%)$ of the chemoradiation group. There was no statistical difference in complete response rate between the two groups. Overall survival rate at 5 years was $73.3\%$. According to stage, overall survival rates at 5 years were $88.9\%$ in stage IB, $85.7\%$ in stage IIA, $73.8\%$ in stage IIB, and $37.5\%$ in stage IIIB, respectively. According to treatment modality, overall survival rates at 5 years were $81.9\%$ in the radiation alone group, $67.0\%$ in the chemoradiation group (p=0.22). Disease-free survival rate at 5 years were $70.4\%$ in the radiation alone group. $68.5\%$ in the chemoradiation group (p=0.85) Locoregional control rates at 5 years were $76.1\%$ in the radiation alone group, $73.8\%$ In the chemoradiation group (p=0.70). Distant disease-free survival rates at 5 years were $83.9\%$ in the radiation alone group, $90.3\%$ in the chemoradiation group (p=0.59). Treatment-related bone marrow suppressions were noted in 3 $(5.4\%)$ patients of the radiation alone group, 14 patients $(17.7\%)$ of the chemoradiation group (p(0.05). Grade 2 vesical complications were noted in 14 patients of the radiation alone group. and 10 Patients of the chemoradiation group. Grade 2 rectal complications were noted in 2 patients of the radiation alone group, and 3 Patients of the chemoradiation group. One case of rectal perforation was noted in the chemoradiation group, and grade 2 small bowel obstructions were noted in 2 patients of the radiation alone group. There were no statistical differences in the incidence of vesicar, rectal, and small bowel complicaions between the two groups. Conclusion: No statistical difference was found between the radiation alone group and the chemoradiation group in terms of response, survival, and failure. but the incidence of bone marrow suppression was higher in the chemoradiation group.
Purpose : Between January 1983 and December 1988, 218 female Patients with known breast cancer and positive axillary nodes were treated with adjuvant radiotherapy and chemotherapy following radical mastectomy. Treatment results were retrospectively analysed at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University of College of Medicine. Materials and Methods : The patients were classified into 3 groups; group I included II patients treated with adjuvant chemotherapy alone; in group 2, 52 patients treated with radiotherapy alone; and in group 3, n patients treated with combined chemo-radiotherapy. The mean age was 44 years and ranged from 27 to 70. The median follow-up time was 51 months. Results :Seven-year relapse free and overall survival rates were 56$\%$ and 67$\%$; in group 1, 50$\%$ and 56$\%$ in group 2, 51$\%$ and 65$\%$ and in group 3, 62$\%$ and 75$\%$ respectively. This difference was not statistically significant(p<0.05). The loco-regional failure rates were 13$\%$ and distant failure rates were 33$\%$. There was less risk of loco-regional failure in group 2 and 3 which included radiotherapy (p<0.05). But there was no significantly difference in the rates of distant failure( p>0.05). By univariate analysis, the only significant prognostic factor affecting relapse-free survival was the percentage of positive axillary nodes; and the overall survival significantly correlated with the primary tumor site, the number or percentage of positive axillary nodes, and stage. But in multivariate analysis, the only significant prognostic factor was treatment modality. By univariate analysis of prognostic factors affecting the rates of overall failure and distant failure, the significant prognostic factors was the percentage of positive axillary nodes; and the risk of the loco-regional failure significantly correlated with the treatment modality. Conclusion :In conclusion, these results suggest a potential for decreasing the risk of loco-regional failure with the addition of postoperative radiotherapy to chemotherapy in the premenopausal patients, and in the patients with number or percentage of positive nodes more than 4 or 1/3. The results of this study suggest that the combined chemo-radiotherapy as adjuvant treatment following radical mastectomy was the most effective modaliw in groups of 2$\~$5 cm sized tumor, stage IIB, and in patients with more than 4 or 1/3 of number or percentage of positive nodes.
In gastric adenocarcinoma, high rates of loco-regional recurrences have been reported even after complete resection, and various studies have been tried to find the role of postoperative adjuvant therapy. Among them, Intergroup 0116 trial was a landmark trial, and demonstrated the definite survival benefit in adjuvant chemoradiotherapy, compared with surgery alone. However, the INT 0116 trial had major limitation for global acceptance of the INT 0116 regimen as an adjuvant treatment modality because of the limited lymph node dissection. Lately, several randomized studies that were performed to patients with D2-dissected gastric cancer were published. This review summarizes the data about patterns of failure after surgical resection and the earlier prospective studies, including INT 0116 study. Author will introduce the latest studies, including ARTIST trial and discuss whether external beam radiotherapy should be applied to patients receiving extended lymph node dissection and adjuvant chemotherapy.
