Fifty-eight were male and 44 cases were female. The age ranged from 9months to 14 years old, with an average of 6.1 ± 0.5 of age. CranialCT or MRI examination was conducted before and after thesurgery on all patients.RESULTS The primary manifestations for this group of patientswere increased intracranial pressure and/or ataxia. Postoperativepathological diagnoses showed: 46 cases of medulloblastoma, 43cases of astrocytoma, 11 cases of ependymoma (including 1 caseof degenerative ependymoma), 1 case of dermoid cyst, and 1 caseof teratoma. In this group of the patients, radical surgery wasused in 68 cases and subtotal surgical removal used in 31 cases,while surgical removal of large section was performed on 3 cases.There were no deaths from surgery reported. Ninety-one casesshowed significant symptomatic improvement when comparedwith preoperative conditions, while 11 cases showed either noimprovement or more severely affected afterward. For 6 cases,postoperative ventriculoperitoneal shunt was performed within7 days to 2 months after the surgery. Sixty-three patients gainedfollow-up for 3 to 60 months in duration. Thirty-nine patientsregained normal life and were able to learn well, while there were7 patients who could not live normally on their own. During thefollow-up period, there were 17 cases of recurrence and 7 casesof death. In 23 cases of medulloblastoma in children with age of3 years old or above, 2 cases who underwent surgical removal ofintracranial ependymoma received small dosage of postoperativeX-ray radiotherapy on the the brain and spinal cord. Nine casesof medulloblastoma in children under age of 3 and 17 cases ofastrocytoma diagnosed after the surgery received chemotherapyof Carmustine.CONCLUSION Medulloblastomas and astrocytomas werethe most common types of pediatric tumor of posterior cranialfossa, right followed by ependymoma, and dermoid cysts andteratomas were rare. Early correct diagnosis, proper selection ofappropriate surgical modality and the surgical margin, propertreatment of postoperative complications, and the selecting rightradiotherapy or chemotherapy were the key factors in influencingthe prognostic outcome of children with tumor of posterior cranialfossa.展开更多

Methods： The clinical and pathological data of 6 patients with SSB treated between 1954 and 2007 were retrospectively analyzed. METHODS The clinical and pathological data of 6 patients with SSB treated between 1954 and 2007 were retrospectively analyzed. RESULTS All patients were female and one was menopausal. The median age of the patients was 39 years old （range, 20-55）. All cases had a history of a palpable mass. The tumor rapidly augmented in a short time period in 3 patients. One patient had discontinuous pain and 3 patients had masses located in the upper outer quadrant of the breast. The median tumor radius was 6.0 cm （range, 3-15 cm）. According to the AJCC breast cancer staging standard （6th edition）, 1 case was of stage ⅡA, 2 cases were of stage ⅡB, 2 cases were of stage ⅢB and one case couldn＇t be staged. Four patients were initially treated by excising the tumor and then undergoing mastectomy or modified radical mastectomy after recurrence. Radical mastectomy was suitable for those with pectoralis major muscle involvement. Two patients received simple mastectom）~ 2 patients underwent radical mastectomy and another 2 patients received modified radical mastectomy. After surgery, all patients were identified as SSB through pathology, with focal ossification in one case and mucinous degeneration in another one case. Four patients who underwent axillary lymph node dissection did not have lymph node metastases. Three patients received chemotherapy after surgery. After a median follow-up time of 36.5 months （8-204 months）, 4 patients had recurrence after local excision and 3 patients had recurrence more than 2 times with a median time to recurrence of 2.5 months （1 to 4 months） after surgery. One patient had lung metastases at 7 months after the initial surgery and the other 5 patients were alive without disease at the end of the follow-up period. CONCLUSION SSB is difficult to diagnose preoperatively and is characterized by its tendency to .recur locally. To obtain negative margins, wide local excision or mastectomy must be performed. Axillary lymph node dissection is not mandatory. The roles of adjuvant chemotherapy and radiotherapy have still been controversial.展开更多
