Purpose: This study was undertaken to evaluate the efficacy of postoperative radiotherapy, and to investigate the prognostic factors for FIGO stages IB-IIB cervical cancer patients who were treated with simple hysterectomy, or who had high-risk factors following radical hysterectomy and pelvic lymph node dissection. Materials and Methods: Between March 1986 and December 1998, 58 patients, with FIGO stages IB-IIB cervical cancer were included in this study. The indications for postoperative radiation therapy were based on the pathological findings, including lymph node metastasis, positive surgical margin, parametrial extension, lymphovascular invasion, invasion of more than half the cervical stroma, uterine extension and the incidental finding of cervix cancer fellowing simple hysterectomy. All patients received external pelvic radiotherapy, and 5 patients, received an additional intracavitary radiation therapy. The radiation dose from the external beam to the whole pelvis was $40\~50$ Gy. Vagina cuff Irradiation was peformed, after completion of the external beam irradiation, at a low-dose rate of Cs-137, with the total dose of $4488\~4932$ chy (median: 4500 chy) at 5 mm depth from the vagina surface. The median follow-up period was 44 months ($15\~108$ months). Results: The 5-yr actuarial local control rate, distant free survival and disease-free survival rate were $98\%,\;95\%\;and\;94\%$, respectively. A univariate analysis of the clinical and pathological parameters revealed that the clinical stage (p=0.0145), status of vaginal resection margin (p=0.0002) and parametrial extension (p=0.0001) affected the disease-free survival. From a multivariate analysis, only a parametrial extension independently influenced the disease-free survival. Five patients ($9\%$) experienced Grade 2 late treatment-related complications, such as radiation proctitis (1 patient), cystitis (3 patients) and lymphedema of the leg (1 patient). No patient had grade 3 or 4 complications. Conclusion: Our results indicate that postoperative radiation therapy can achieve good local control and survival rates for patients with stages IB-IIB cervical cancer, treated with a simple hysterectomy, as well as for those treated with a radical hysterectomy, and with unfavorable pathological findings. The prognostic factor for disease-free survival was invasion of the parametrium. The prognosic factor identified in this study for treatment failure can be used as a selection criterion for the combined treatment of radiation and che motherapy.
Purpose : This is retrospective study to compare the results of radiation therapy alone and neoadjuvant chemotherapy and radiation in advanced stage of uterine cervical cancer. Materials and Methods : Seventy-six Patients who were treated with definitive radiation therapy for locally advanced cervical cacinoma between June 1988 and December 1993 at the department of radiation oncology, Keimyung University Dong-san Hospital. Thirty six patients were treated with radiation therapy alone and forty patients were treated with cisplatin based neoadjuvant chemotherapy and radiation therapy. According to FIGO staging system. there were 48 patients in stage IIb, 3 patients in stage IIIa, 23 patients in stage lIIb and two patients in stage IVa with median age of 53 years old. Follow-up periods ranged from 7 to 95 months with median 58 months. Results : Complete response (CR) rate were $86.1\%$ in radiation alone group and $80\%$ in chemoradiation group. There was no statistical difference in CR rate between the two groups. Overall five-year survival rate was $67.3\%$. According to stage, overall five-rear survival rates were $74\%$ in stage IIb, $66.7\%$ in stage IIIa, $49.8\%$ in stage IIb, $50\%$ in stage IVa. According to treatment modality overall five year survival rates were $74.1\%$ in radiation alone and $61.4\%$ in chemoradiation group (P=0.4) Five rear local failure free survival rates were $71.5\%$ in radiation alone group and $60\%$ in chemoradiation group (P=0.17). Five year distant metastasis free survival rates were $80.7\%$ in radiation aione group and $89.9\%$ in chemoradiation group (P=0.42). Bone marrow suppression (more than noted in 3 cases of radiaion alone group and 1 case of chemoradiation group. Grade II retal complication was noted in 5 patients of radiation group and 4 patients In chemoradiation group. Bowel obstruction treated with conservative treatment (1 patient) and bowel perforation treated with surgery (1 patient) were noted in radiation alone group. There was no statistical difference in complication between two groups. Conclusion : There was no statistical difference in survival, failure and complication between neoadjuvant chemotherapy and radiation versus radiation alone in locally advanced uterine cervical carcinoma.
Purpose :The aim of this study is to analysis of suwival and recurrence rates of the uterine cervical carcinoma patients whom received the radiation therapy respectively. The prognostic factors, such as Papanicolaou (Pap) smear, carcinoembriogenic antigen (CEA) and squamous cell carcinoma (SCC) antigen has been studied. Methods and Materials : From January 1981 to December 1998, eight-hundred twenty-seven uterine carvical cancer patients were treat with radiation therapy. All of the patients were divided into two groups : the radiation therapy only (S2l patients) group and the postoperative radiation therapy (326 patients) group. The age, treatment modality, clinical stage, histopathology, recurrence, follow-up Pap smears, CEA and SCC antigen were used as parameters for the evaluation. The prognostic factors such as survival and recurrence rates were peformed with the Kaplan-Meier method and the Cox hazard model, respectively. Median rollow-up was 38.6 months. Results :On the radiation therapy only group, 314 patients (60$\%$) achieved complete response (CR), 47 patients (9$\%$) showed local recurrence (LR), 78 patients (15$\%$) developed distant metastasis (DM). On the Postoperative radiation therapy group, showed 276 Patients (85$\%$) CR, 8 Patients (2$\%$) LR, 37 Patients (11$\%$) DM. The 5-year survival and recurrence rates was evaluated for all parameters. The statistically significant factors for the survival rate in univariate analysis were clinical stage (p=0.0001), treatment modality (p=0.0010), recurrence (p=0.0001), Pap smear (p=0.0329), CEA (p=0.0001) and SCC antigen (p=0.0001). Conclusion: This study indicated that after treatment, the follow-up studies of Pap smear, CEA and SCC antigen were significant parameter and prediction factors for the survival and recurrence of the uterine cervical carcinoma.

A primary malignant melanoma of the vagina is a very rare gynecological malignant tumor. Its clinical behavior is more aggressive than that of cutaneous and vulvar melanomas. We present a case of a large sized primary melanoma of the lower third of the vagina, with a cervical lesion, in a 58-year-old postmenopausal woman. The patient was treated with conventional external radiation therapy and intracavitary radiotherapy (ICR), without surgical treatment. Although the primary lesion showed a partial response, the patient died of extensive metastases, which were found 4.5 months after the initial diagnosis. We suggest that shortening the treatment period, such as hypofractionated radiation therapy and surgical removal, and various systemic therapies for preventing early distant metastasis, are appropriate treatments for a primary malignant melanoma of the vagina, with a large tumor size.

Background and Objectives: Supraglottic cancer have a great tendency to spread cervical lymph nodes and lymph node metastasis is a well known prognostic factor. However the treatment for N0 neck in supraglottic cancer is still controversial. Materials and Methods: We retrospectively analyzed our neck management of supraglottic cancer patients who present with cN0 contralateral neck from 1989 through 1997. 36 patients were eligible for analysis. The primary site was surgically removed and the neck was managed by elective neck irradiation (ENI), elective neck dissection (END), or therapeutic neck dissection (TND) with postoperative radiation therapy (PORT). Results: Our results revealed that 18 of 36 patients have clinically negative neck, another 18 patients have clinically positive neck (N1-3). In clinically negative group, 12 of 18 patients were received ENI and there was 1 failure in contralateral neck area. Remaining 6 patients were received END with PORT and there was no failure. In clinically positive neck group, 3 of 18 patients were received ipsilateral TND and an additional contralateral END with PORT. Remaining 15 patients who were received TND with PORT, developed 3 neck failure. Conclusion: ENI or ipsilateral or bilateral END can be done in the cN0 neck of supraglottic cancer however ipsilateral TND and contralateral END with PORT is reasonable for the cN(+) neck.
This study aimed to evaluate the prevalence of preoperative thrombocytosis and its prognostic significance in Thai patients with endometrial cancer. We retrospectively reviewed the medical records of 238 cases who had undergone surgical staging procedures between January 2005 and December 2008. Associations between clinicopathological variables and preoperative platelet counts were analyzed using Pearson's chi square or two-tailed Fisher's exact tests. Survival analysis was performed with Kaplan-Meier estimates. Univariate and Cox-regression models were used to evaluate the prognostic impact of various factors including platelet count in terms of disease-free survival and overall survival. The mean preoperative platelet count was $315,437/{\mu}L$ (SD $100,167/{\mu}L$). Patients who had advanced stage, adnexal involvement, lymph node metastasis, and positive peritoneal cytology had significantly higher mean preoperative platelet counts when compared with those who had not. We found thrombocytosis (platelet count greater than $400,000/{\mu}L$) in 18.1% of our patients with endometrial cancer. These had significant higher rates of advanced stage, cervical involvement, adnexal involvement, positive peritoneal cytology, and lymph node involvement than patients with a normal pretreatment platelet count. The 5-year disease-free survival and overall survival were significantly lower in patients who had thrombocytosis compared with those who had not (67.4% vs. 85.1%, p=0.001 and 86.0% vs. 94.9%, p=0.034, respectively). Thrombocytosis was shown to be a prognostic factor in the univariate but not the multivariate analysis. In conclusion, presence of thrombocytosis is not uncommon in endometrial cancer and may reflect unfavorable prognostic factors but its prognostic impact on survival needs to be clarified in further studies.
This 32 year old female patient underwent left radical mastectomy due to ductal carcinoma on May 1990, and treated with FAM (5-fluorouracil, Adriamycin and Mitomycin C) regimen postoperatively. However, right cervical Iymph node enlargement and facial edema progressively developed since December 199). On April 1994, operation was performed, and findings were as followes; x4$\times$5$\times$7 to 1 : 1 $\times$ 1 cm sized multiple enlarged and hyperemic Iymph nodes were scatterred throughout submandibular area to the junction of superior vents cave and pericardium, and partially invaded both anterior segmental lobe, sternum and both distal tip of clavicles. After radical dissection of the nodes of neck and mediastinal nodes, and wedge resection of both anterior segments of lung, and partial resection of both clavicle tips and total sternum. The both innominate veins and superior vena cava were partially obstructed by invaded cancer SVC reconstruction was done with preclotted 10$\times$ 10$\times$ 18mm Y shap d woven Dacron graft, which was anastomosed to the point of the junction of subclavian vein and jugular vein after cross clamping both veins and 2cm above the pericardial junction with one arm clamp. After maintaining blood drainage to the SVC from the right side, left innominate vein was anastomosed with 4-0 Prolene continuous running suture. Bone cement was used for resected sternal portion and clavicular ends were fixed to postal portion with 18 Gauge wires. The patient was treated with radiation and chemotherapy after discharge, and there were no evidence of regrowing of the mass nor obstruction of the graft inspite of no antithrombotic therapy.

Objective: To compare the clinical effects of concurrent radiochemotherapy with those of radiotherapy in treating locally advanced nasopharyngeal carcinoma (Stage III~IVa). Methods: A total of 95 patients suffering from nasopharyngeal carcinoma (Stage III~IVa) were divided into two groups: concurrent radiochemotherapy (Group CCRT, n=49) and radiotherapy (Group RT, n=46). The two groups were both delivered conventional fractionated radiotherapy, while Group CCRT also received three cycles of PF (DDP+5-Fu) or PLF (DDP+5-Fu+CF) chemotherapy. Results: The complete remission rate and total remission rate of Group CCRT were higher than those of Group RT ($X^2$=4.72~7.19, P<0.05). The one-year overall survival (OS) rate calculated by the life table method, was also higher than that of Group RT ($X^2$=4.24, P<0.05) as well as the 3-year OS rate, nasopharyngeal control rate and cervical lymph nodes' control rate ($X^2$=4.28~4.40, P<0.05). In addition, the 5-year OS and metastasis-free rates of Group CCRT were higher than those of Group RT and the differences were of statistical importance ($X^2$=3.96~8.26, P<0.05). However, acute toxicity was also obviously higher, the difference in gastrointestinal reactions being statistically significant ($X^2$=11.70, P<0.05). Conclusion: This study demonstrated that concurrent radiochemotherapy could improve the remission rate, overall survival rate and locally control rate. The toxicity of concurrent radiochemotherapy could be tolerated by the patients.
Objective: We aimed to define clinicopathologic risk factors associated with regional recurrence (RR) and thus the effectiveness of postoperative radiotherapy (PORT) for neck control for head and neck squamous cell carcinomas (HNSCCs) with differing cervical lymph node status. Methods: A retrospective study was performed in 196 HNSCC patients with pathologically positive neck node (N+) to evaluate the high-risk factors for RR and to define the role of PORT in control after neck dissection and postoperative radiotherapy (PORT). Results: Overall, the RR rate after neck dissection and PORT was 29%. Extracapsular spread (ECS) was confirmed to be the only independent risk factor for RR. There were no significant risk factors associated with RR in the ECS- group. The 5-year disease-specific survival rate was 45%, which descended to 10% with the emergence of RR. Conclusions: ECS remains a determined risk factor for RR after neck dissection and PORT in patients with N+. PORT alone is not adequate for preventing RR in the neck with ECS after neck dissection. More intensive postoperative adjuvant therapies, especially combined chemotherapy and radiotherapy, are needed to prevent regional failure in HNSCC patients with ECS.
Objectives: Head and neck squamous cell carcinoma (HNSCC) is the most common head and neck malignant tumor. The molecular genetic changes involving both oncogenes and tumor suppressor genes are known to be involved in head and neck squamous cell carcinogenesis, but the roles of the known tumor suppressor genes in carcinogenesis are not fully elucidated. The objectives of this study are to demonstrate the genetic alterations including the loss of heterozygosity (LOH) , amplification, and microsatellite instability of known tumor suppressor genes in HNSCC and to evaluate the relationship between genetic alterations of tumor suppressor genes and clinicopathologic features. Materials and Methods: Genetic alterations of 10 micro satellite markers of the 6 known tumor suppressor genes (APC, EXT1, DPC4, p16, FHIT, and PTEN) were analysed by DNA-PCR in paraffin-embedded histologically confirmed HNSCC specimens. Results: The genetic alterations of tumor suppressor genes were found frequently. Among the genetic alterations, LOH was most frequently found one. LOH was found frequently in APC (45.4%), EXT1 (36.4%), DPC4 (54.5%), and p16 (50%), but not found in FHIT. Also, the author found that abnormalities of APC gene was related to cervical lymph node metastasis and recurrence and that abnormalities of EXT1 gene were coexisted with those of APC gene or DPC4 gene. But these coexistences had no correlation with clinical features. Conclusion: These results suggested that APC, EXT1, p16, and DPC4 genes might play important roles and multiple tumor suppressor genes may participate dependently or independently in the carcinogenesis of HNSCC. These results also suggested that APC gene might relate to prognosis.
