Objective To investigate the curative effect of synchronous radio-chemotherapy in medium-term and advanced cervical carcinoma. Methods 168 cases of medium-term and advanced cervical carcinoma were selected. The treatment group(grout A) included 84 pathologically verified cases of stage Ⅱ～Ⅳ cervical carcinoma. Each patient was given DDP with hydration at the dose of 40 mg/m2 intravenously.The treatment cycle was performed once every week for 3--4 circles. Radiotherapy was given at the same time. 60Co was used for external radiation with a total dose of 50 Gy, 192 Ir afterloading unit was used for brachytherapy at the dose of 7 Gy per week at point A with a total dose of 42 Gy. The control group (group B)included 84 cases of cervical carcinoma at the same stage in the corresponding period who received radiotherapy only.Short-term effect ,2-year survival rate and complications were observed. Results Effective rate was 92.85 %(78/84) in group A and 79.76 %(67/84) in group B respectively 3 months after radiotherapy, showing a significant difference(χ2 =6.10,P <0.05). 2-year survival rate was higher in group A (83.95 %) than in Group B(60.98 %) (χ2 =9.4,P<0.05). Local recurrent and distant metastasis were lower in Group A than Group B. In group A, there were tolerable bone marrow inhibition and reaction of digestive tract. Conclusion Synchronous radiotherapy and chemotherapy can remarkably improve the survival rate of medium-term and advanced cervical carcinoma. The application of DDP is effective and safe,and its side effect can be accepted by patients, but the long-term effect needs further observation.

Objective To evaluate the impact of different factors on long-term results in cervical carcinoma patients initially treated by surgery followed by radiotherapy. Methods In 1998, 525 cervical carcinoma patients were admitted, among whom 346 patients were first treated by surgery. 302 of these 525 patients were given postoperative radiotherapy. The stage distribution of these 302 patients were: stage I 142;stage Ⅱa 121;stage Ⅱb 23;and stage Ⅲa 16. ~ 60 Co ? or 6MV X-ray was used for radiotherapy. Perpendicular portals were alternately irradiated to 44-50Gy/4-5 week. Extending the portal, increasing the dose after constricting portal, adding intracavitary afterloading irradiation and adjuvant chemotherapy were carried out according to the different clinical requirements. Results The 5-year survival rate was 89.4%,77.7%,56.5% and 56.3% in stage I, Ⅱa, Ⅱb and Ⅲa lesion, respectively(?~2=22.22,P

Objective To eompare the dose distribution of three-dimension conformal radiation therapy(3DCRT) and common radiation therapy (CRT) of the planning target volume(PTV) and organ at risk (OAR) in recurred cervical cancer treatment planning. Methods Thirteen patients,who had cervical cancer recurred in pelvis treated with 3DCRT in Shanxi Cancer Hospital from May to August 2007, were selected. After CT simulation, the CT images were transferred into Topslane treatment system. The same physicist designed 3DCRT plan and common radiation therapy plan for every patient,total dose 50 Gy, 90 % is dose covered PTV, then compared the dose distribution of PTV and OAR.Results At the same prescribed dose of 50Gy,there were no significant differences on OAR maximum dose between 3DCRT plans and common radiation therapy plans(P >0.05), however, there was significant differences on PTV maximum dose(P <0.01). The difference of PTV uniformity were significant between 3DCRT plans and common radiation therapy plans (P <0.001). Compared the high dose region of OAR(V40), the difference was significant (P <0.001). Between 3DCRT plans and common radiation therapy plans, they showed 53.31 ml (90.69 %), 124.00 ml (79.47 %), 655.16 m1(92.22 %) median reduction in the V40 of rectum, bladder, intestine, respectively. Conclusion At the same PTV coverage of the prescribed dose, 3DCRT plans showed worse dose uniformity, however, the radiation volume to organs at risk in 3DCRT plans were smaller than common radiation therapy plans. So patients with cervical cancer recurred in pelvis received 3DCRT may be potentially diminish the Normal Tissue Complications Probability(NTCP).

Tumor radiotherapy is established on the basis of clinical oncology, radio-physics and radiobiology, and has become one of the three major therapeutic methods for malignant tumors. With the pace of socialist construction in China, the subject of radiotherapy in Shanxi province has developed from scratch and from small to large for more than 60 years. Remarkable achievements have been made in the establishment of departments, the updating of technical equipment, the increase of employees and clinical scientific research. This article reviews and summarizes the development history of tumor radiotherapy in Shanxi province.
