Objective To evaluate the oncologic risks of skin sparing breast conserving surgery for carcinoma of breast at early stage.Methods Serial sections of skin overlying the tumor were done for pathological examination in 50 cases of early stage breast cancer after skin sparing breast conserving operation.Results In 50 cases of breast conserving surgery,the extent of skin removal was 0.5-1.0cm in 21 cases,1.0-1.5cm in 25 cases,and 1.5-2.0cm in 4cases.Skin involvement was found in one patient with stage Ⅱ breast cancer,and the rate of skin involvement was 2%.Skin involvement was closely related with the changes in skin overlying the tumor,but not with the tumor size,pathologic types or axillary lymph node metastasis.Conclusion The rate of skin involvement in early stage breast cancer is rare,therefore if there are no abnormal clinical manifestations in the skin,skin sparing breast conserving surgery is safe.

Objective This paper studies on feasibility of low dose CT scanning in lung cancer patients simulated localisation.Methods 62 patients cases of lung cancer are selected.Scan parameter:scan twice by 20/100 mA,the other parameter remain unchanged as voltage of 120 kV,thickness of 5 mm,pitch of 1:1 and scan time of 1 s.After scan,picture quality was evaluated according to excellent,good,bad under different condition.Volume of target was determined by treatment planning system.Data such as dose index value of single helical scan,z-axis scan range,dose length product value and etc.are recorded in order to evaluate radiation dose of patients.Picture quality and the difference of radiation dose were statistically analyzed using Fisher's and pair t-test.Results Picture quality of low dose scanning was a little bit lower than that of normal dose,however,picture quality difference of difference dose scanning was statistically meaningless (number of patients according to excellent,good,bad were 46,13,3 and 50,11,1,P =0.541).There is no obvious difference of target volume under different dose scanning in the same (36.78 cm3,40.35 cm3,t =2.57,P =0.189).Radiation dose of low dose scanning group is far less than that of high dose scanning group and the difference is obvious (133.05 mGy,941.25 mGy,t =-41.24,P =0.000).Conclusions Low dose scanning of 20 mA current during CT simulated localisation tremendously reduces harm that may happen to patients during CT scan,while tumor target delineation and scanned picture quality is guaranteed.

BACKGROUND:Traditional core decompression and al ograft fibula supporting can reduce the stress load within femoral head and improve mechanical properties of femoral head. However, it cannot provide supports for maintaining the stability of five pathological areas fol owing femoral head necrosis. OBJECTIVE:To observe the clinical effect of fan-shaped decompression and al ograft fibula supporting internal fixation in treatment of early femoral head necrosis in adults, taking al ograft fibula grants as the control. METHODS:Forty patients with early femoral head necrosis were randomly divided into treatment group and control group, receiving fan-shaped decompression plus al ograft fibula supporting internal fixation and traditional decompression plus al ograft fibula grafting, respectively. The therapeutic effects in two groups were observed and compared. After treatment, patients were detected by bilateral hip anteroposterior films, Harris scoring and X-ray ARCO staging to evaluate the col apse severity and restoration of necrosis. RESULTS AND CONCLUSION:At the last fol ow-up, Harris scores in the treatment group were significantly higher and the repairing effect was better than control group (P<0.05). In treatment group, 18 hips restored wel (72%) and 7 hips delayed or failed to restore (28%);in control group, 9 hips restored wel (60%) and 6 hips delayed or failed to restore (40%). Our findings indicate that, fan-shaped decompression plus al ograft fibula supporting internal fixation yields a more complete decompression, a higher stability of femoral head and a more reliable supporting, compared with traditional decompression plus al ograft fibula grafting.

Objective To evaluate whether ultrasonographic features of thyroid nodules are associated with histological malignancy, and to set up helpful criteria in identifying those who should accept subsequent fine-needle aspiration biopsy (FNAB). Methods 146 thyroid nodules of 123 patients accepted ultrasonographic evaluation and FNAB. All patients but one with suspicious or malignant cytology were operated. Results Out of total 146 nodules, 43 were histologically malignant, 102 were cytologically benign, and 1 nodule with suspicious cytology was not followed. Hypoechoic pattern, blurred margins, irregular shape, microcalcification, and type Ⅲ vascularity were significantly more frequent in malignant than benign nodules (P ＜ 0. 05). No one of the ultrasonographic features could independently predict malignant nodules. A better compromise is probably to apply FNAB in nodules with at least one or two malignant ultrasonographic signs. Conclusion No single parameter could satisfactorily identify a subset of patients to be selectively examined by FNAB. A cost-effective approach to FNAB should depend on combination of specific ultrasonographic features.
