OBJECTIVE The purpose of the study was to examine the efficacy of treating patients with advanced gastric cancer using iodine-125 (^125Ⅰ) brachytherapy. METHODS Ten patients with unresectable advanced gastric cancer were selected based on their pattern of CT scans. We utilized a brachytherapy planning system to determine the distribution of the ^125Ⅰ seeds, their activity and quantity. The matched peripheral dose (MPD) was 110-135 Gy.^125Ⅰ seeds were implanted in a single plane or biplane by an intraoperative small incision or percutaneous puncture. The postoperative hemogram, CT, KPS, pain-relieving period and survival period were recorded. RESULTS One patient developed a complete response (CR), 4 patients a partial response (PR), 3 patients showed no change (NC) and 2 patients developed progressive disease (PD). The overall response rate (CR+PR) was 50% (5/10). The pain-relieving rate was 89% (8/9). The patients' appetite and KPS were improved. The longest survival period was 10 months and median life span was 4 months. There were 8 patients whose seeds fell off resulting in an expulsion rate of 3.8% (26/692). The patients showed 0-1 degree acute radio-therapeutic side-effects without other symptoms such as abdominal pain, vomitus cruentes or intestinal obstruction etc.CONCLUSION Applying ^125Ⅰ implantation to treat advanced gastric cancer with a reasonable seed distribution can significantly improve clinical symptoms and their quality of life. The radioactive damage is mild. This method can be used as an important supplementary treatment for unresectable advanced gastric cancer. 展开更多

Objective: The senile lung adenocarcinoma patients harboring an activating epidermal growth factor receptor (EGFR) mutation shows good and rapid response to EGFR tyrosine kinase inhibitors (TKIs). Whether gefitinib combined with y-ray stereotactic body radiation therapy has better efficacy than gefitinib alone for senile lung adenocarcinoma patients with EGFR mutations as first-line regimen is still under investigation. Methods: The 42 senile lung adenocarcinoma patients with EGFR mutations were divided into 2 groups according to the therapy method. Group A was the 22 patients treated with gefitinib combined with y-ray stereotactic body radiation therapy (SBRT). Group B was the 20 patients treated with gefitinib alone. All of the patients received gefitinib of 250 mg/d from the first day until disease progression or other reasons. The patients of Group A were treated with y-ray stereotactic body radiation therapy from the second day. Radiation fields included the primary lesions and the integration of lymph nodes. Dose curve of this group was 50%-80%. Encircled dose was 4.0-6.5 Gy per fraction and the range of total dose was 40-52 Gy. We treated the patients 8-12 times and treated five times every week. Results: All the patients were examined by enhanced double helix CT at the second month. The tumor response rate (RR) of group A was 81.8% (18/22). Disease control rate (DCR) was 90.9% (20/22). The median overall survival (OS) was 24.2 months (range 8-58 months ) and the progression-free survival (PFS) was 18.6 months. The overall 1-year survival rate was 72.3% (16/22) and 2-year survival rate was 54.5% (12/22). The main side effects included skin rash and diarrhea. The RR of group B was 50.0 % (10/20). DCR was 75.0% (15/20). OS was 17.4 months (range 6-32 months ) and PFS was 12.1 months. The overall 1-year survival rate was 60.0% (12/20) and 2-year survival rate was 40.0% (8/20). The main side effects included skin rash and diarrhea. The group A who were treated with gefitinib combined with y-ray stereotactic body radiation therapy had a higher short term therapeutic effects (RR) and long term therapeutic effects (OS) than group B who were treated with gefitinib alone respectively (81.8% vs 50.0%, P = 0.029 〈 0.05, x2 = 4.773 and 24.2 vs 17.4, P = 0.024 〈 0.05, X2 = 5.098). Conclu. sion: Gefitinib combined with y-ray stereotactic body radiation therapy has better efficacy than gefitinib alone for senile lung adenocarcinoma patients with EGFR mutations as first-line regimen. The side affects are acceptable. 展开更多

Bleeding from esophageal varices (EVs) is a catastrophic complication of chronic liver disease. Many years ago, surgical procedures such as esophageal transection or distal splenorenal shunting were the only treatments for EVs. In the 1970s, interventional radiology procedures such as transportal obliteration, left gastric artery embolization, and partial splenic artery embolization were introduced, improving the survival of patients with bleeding EVs. In the 1980s, endoscopic treatment, endoscopic injection sclerotherapy (EIS), and endoscopic variceal ligation (EVL), further contributed to improved survival. We combined IVR with endoscopic treatment or EIS with EVL. Most patients with EVs treated endoscopically required follow- up treatment for recurrent varices. Proper management of recurrent EVs can significantly improve patients’ quality of life. Recently, we have performed EVL at 2-mo (bimonthly) intervals for the management of EVs. Longer intervals between treatment sessions resulted in a higher rate of total eradication and lower rates of recurrence and additional treatment. 展开更多

A 78-year-old man with liver cirrhosis was found to have multiple hepatocellular carcinomas (HCCs) and underwent 3 sessions of transcatheter arterial chernoernbolization. Fourteen months after diagnosis, the patient presented with left herniparesis. Contrast- enhanced magnetic resonance imaging showed multiple metastases with ring-shaped enhancement in the cerebrum and cerebellum. There were no metastases to other organs. The metastatic lesions almost completely disappeared after whole-brain radiotherapy with a total dose of 50 Gy. Neurologic symptoms decreased, and the patient's quality of life improved. The patient underwent 2 more sessions of transcatheter arterial chemoembolization. Twelve months after the diagnosis of brain metastasis, the patient remains alive. The present case indicates that radiotherapy can improve quality of life and prolong survival in some patients with brain metastases from HCCs. 展开更多

Any prognosis of gastrointestinal (GI) cancer is closely related to the stage of the disease at diagnosis.Endoscopic submucosal dissection (ESD) and en bloc endoscopic mucosal resection (EMR) have been performed as curative treatments for many early-stage GI lesions in recent years.The technologies have been widely accepted in many Asian countries because they are minimally invasive and supply thorough histopathologic evaluation of the specimens.However,before engaging in endoscopic therapy,an accurate diagnosis is a precondition to effecting the complete cure of the underlying malignancy or carcinoma in situ.For the past few years,many new types of endoscopic techniques,including magnifying endoscopy with narrow-band imaging (MENBI),have emerged in many countries because these methods provide a strong indication of early lesions and are very useful in determining treatment options before ESD or EMR.However,to date,there is no comparable classification equivalent to "Kudo's Pit Pattern Classification in the colon",for the upper GI,there is still no clear internationally accepted classification system of magnifying endoscopy.Therefore,in order to help unify some viewpoints,here we will review the defining optical imaging characteristics and the current representative classifications of microvascular and microsurface patterns in the upper GI tract under ME-NBI,describe the accurate relationship between them and the pathological diagnosis,and their clinical applications prior to ESD or en bloc EMR.We will also discuss assessing the differentiation and depth of invasion,defying the lateral spread of involvement and targeting biopsy in real time. 展开更多

OBJECTIVE To analyze the relationship between the characteristics of PET/CT images for lung carcinoma(LC)TNM staging and the expression of serum VEGF protein. METHODS PET/CT examinations were performed before treatment of 53 patients with LC.The expression of serum VEGF protein was examined using a quantitative sandwich enzyme-linked immunosorbent assay(ELISA R and D system).The relationship was analyzed between PET/CT images for LC T-staging and metastasis(lymph nodes and distance)and serum VEGF expression. RESULTS Based on PET/CT images for LC T-staging,11 cases were staged as T1,9 as T2,18 as T3 and 15 as T4.Mediastinal nodal metastases were found in 22 patients,and distance metastasis in 9.The serum VEGF level in the LC patients was(378.02±180.79)ng/L,showing that there was a significant difference between the patients and healthy subjects(P<0.05). There was no significant difference in the level of serum VEGF between different low T-staged(T1,T2)patients.However,the level of serum VEGF was significantly different between the low T-staged(T1,T2)and high T-staged (T3,T4)patients(P<0.05).The level of the serum VEGF protein in the patients with mediastinal nodal metastasis was(561.50±104.55)ng/L,and indicating that there was a statistical significance(t=12.21,P<0.05)compared to those in the non-metastatic group.The level of serum VEGF in the patients with distance metastasis was(614.11±158.81)ng/L,demonstrating that there was a significant difference(t=5.30,P<0.05)compared to those in the nondistant metastatic group. CONCLUSION ① There is a high level of serum VEGF expression in LC patients.②There is a correlation between metastases(lymph nodes and distance)and the level of serum VEGF. ③ With an upgrade of the TNM-stage,the level of serum VEGF protein is elevated. 展开更多

Objective: This study was done to compare between the effect of preoperative radiotherapy and postoperative radiotherapy in treatment of resectable rectal carcinoma. The primary endpoints are local recurrence rate, overall survival (OS) and disease free survival (DFS). The secondary endpoints are to evaluate down-staging, treatment toxicity, and ability to do sphincter preservation, aiming at choosing the optimal treatment modality. Methods: This study included 100 patients with resectable rectal carcinoma who presented to Surgical Gastro Entrology Center and Clinical Oncology and Nuclear Medicine Department, Mansoura University during the period between January 2007 and September 2009. The included patients were randomized in two groups; group h 50 patients received preoperative radiotherapy and group Ih 50 patients received post- operative radiotherapy. Concurrent 5-fluorouracil-based chemotherapy was given to all patients. Two major types of surgery were done: abdomino-perineal resection with a permanent colostomy and low anterior resection with colorectal or coloanal anastomosis. Results: Preoperative radiotherapy resulted in pathologic complete response in 3 patients. T down-staging occurred in 18 out of 50 patients (36%) with statistically significant difference (P = 0.008). N down-staging occurred in 10 out of 24 patients. Sphincter preservation was more in group I. Delayed wound healing was the most common postoperative complication in group I with no significant difference. After a median follow up of 18 months, local recurrence rate and distant metastasis were higher in group I1. The 2-year disease free survival was 72% and 60% in group I and II respectively with no statistically significant difference between both groups. Conclusion: This study concluded that preoperative radiotherapy is better than postoperative radiotherapy as regard local control, sphincter preservation with higher disease free survival and overall survival. No difference in treatment toxicity between both groups. 展开更多

Group C was the 42 patients treated with gefitinib. Group D was the 31 patients treated with best supportive therapy. The patients received gefitinib of 250 mg/d from the first day until disease progression or other reasons. The patients were treated with γ-ray stereotactic radiotherapy from the second day. Dose curve of this group of cases was 50%-80%. Encircled dose was 4.0-6.5 Gy per fraction and the range of total dose was 36-48 Gy. The total number of treatment was 8-12 and treated six times every week. Results: All the patients were examined by enhanced double helix CT at the second month. The tumor response rate (RR) of group A was 68.6% (24/35). Disease control rate (DCR) was 88.6% (31/35). The median survival time (MST) was 13.4 months (range 3-34 months ) and the progression-free survival (PFS) was 7.8 months. The overall 1-year survival rate was 40.0% (14/35). The main side effects included skin rash and diarrhea. The RR of group B was 51.1% (23/45). DCR was 71.1% (32/45). MST was 9.6 months (range, 3-18 months ) and PFS was 5.3 months. The overall 1-year survival rate was 15.6 % (7/45). The RR of group C was 40.5 % (17/42). DCR was 61.9% (26 /42). MST was 10.3 months (range, 3-26 months ) and PFS was 5.1 months. The overall 1-year survival rate was 35.7 % (15/42). The main side effects included skin rash and diarrhea. The MST of group D was 5.6 months (range, 2-11 months ) and PFS was 1.7 months. The overall 1-year survival rate was 0. The short-term therapeutic effects (RR) of group A was higher than group C (P = 0.014 < 0.05, χ2 = 6.053) but has no significant difference with group B (P = 0.116 > 0.05, χ2 = 2.477). The long-term therapeutic effects (overall 1-year survival rate) of group A was higher than group B (P = 0.014 < 0.05, χ2 = 6.077) but has no significant difference with group C (P = 0.642 > 0.05, χ2 = 0.216). Conclusion: Gefitinib combined with γ-ray stereotactic radiotherapy is feasible and effective for treatment in senile patients with adenocarcinoma of lung as the first-line regimen. 展开更多

Recently, the paper by Wang et at published in World Journal of Gastroenterology has given rise to great interest of many researchers. It is well known that hepatoma is one of the lethal diseases with a high incidence in the world, especially in Asia. Radiotherapy is the main treatment modality of hepatoma in clinical practice. Unfortunately, intrinsic radiosensitivity of cancer cells is not fully understood, though a large number of papers on it are now available. Yang and colleagues 21 have developed the premature chromosome condensation technique for clinical radiotherapy of hepatoma. A precise and quick measurement of cell radiosensitivity can detect the highrisk results after exposure to a large dose. 展开更多

Objective: To observe the efficacy of stereotactic radiotherapy (SRT) in lung cancer patients with brain metas-tases and explore the nursing for those patients. Methods: From June 2002 to December 2006, 43 patients of lung cancer with brain metastases were treated with SRT, 8 of them were treated with the association of whole-brain radiotherapy (WBRT) and 6 of them were treated with combination of chemotherapy. During the period of SRT, the patients were applied with active psychological nursing and diet nursing. We also tried to prevent patients from epicranium injury, and meanwhile, patients were asked to took active convalesce exercise. Results: All patients finished SRT without serious reaction and complication. Local control rate was 81.4%, nervous system symptoms relief rate was 76.7% and KPS score was raised significantly. Survival time ranged from 2 to 34 months, median survival time was 8.5 months, and 6-month, 1-and 2-year survival rates were 58.9%, 26.2%, and 6.0% respectively. Conclusion: SRT was one of the effective palliation treatments for the lung cancer patients with brain metastases, and with the assistance of effective nursing, which would prolong their survival time and improved quality of life. 展开更多

Objective: To evaluate the clinical effects of concurrent and sequential therapy for middle and advanced stage non-small cell lung cancer (NSCLC) useing IMRT combined with NP regimen chemotherapy. Methods: Eighty patients with middle and advanced stage NSCLC were randomized into two groups. Forty patients were underwent sequential therapy and other 40 patients were underwent concurrent therapy. IMRT was used in radiotherapy and NP regimen of vinorelbine+cispatin (NP) was used in chemotherapy. Results: (1) The overall response (CR+PR) rate was 75% in concurrent group and 45% in sequential group (P<0.05); (2) The treatment courses were 84 days and 140 days for concurrent group and sequential group respectively (P<0.05); (3) One-year survival rate in concurrent group was 72.4% and 52.3% in sequential group respectively; (4) The toxic effects can be tolerable by all of patients. Conclusion: The concurrent chemo-radiotherapy has better overall re- sponse, one-year survival rate and shorter treatment course than the sequential chemo-radiotherapy, so it is a better method for the treatment of middle and advanced stage NSCLC, but the long term survival rate will be studied. 展开更多
