Primary hepatic lymphoma is a rare disorder representing less than 1% of all extranodal lymphomas. Histological examination of a primary hepatic lymphoma usually reveals a diffuse large B-cell lymphoma; there have been few reports of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphomas. A 67-year-old man was being treated for a duodenal ulcer; while receiving therapy for the ulcer, a liver mass was incidentally found on abdominal ultrasonography. The pathologic diagnosis of the hepatic mass was an extranodal marginal zone B-cell lymphoma of MALT. The patient underwent radiotherapy with a total of 4,140 cGy delivered. The patient achieved complete remission and has been followed for 6 years with no recurrence of the disease. This report reviews the case of a primary hepatic extranodal marginal zone B-cell lymphoma of MALT successfully treated by radiotherapy alone.

Synovial sarcoma is a rare tumour found in soft tissue; it is a mesenchymal spindle cell tumour that is not related to the synovial membrane. This tumour has a low incidence, and the most frequent place of occurrence is the lower extremities in young adults. Synovial sarcoma of the head and neck accounts for 3%-5% of sarcomas in this anatomical region. The tumor in the nasal cavity is less than 1%. The treatment of choice for synovial sarcoma of the head and neck is complete surgical excision of the tumour mass followed by adjuvant radiotherapy.

Fractionation dose and number have been known as radiation factor affecting the radiation complication and the effectiveness in radiotherapy for brain tumors. In this study hyperfractionation technique with 115cGy/fractioin 2 fractions daily 5days/wk, upto 5750-6900cGy to partial brain volume was compared with conventional fractionation technique with daily 200cGy/fraction 5 fraction/wk, upto 5400-6000cGy, in regarding to the effectiveness of hyperfractionated radiotherapy and eraly and later radiation reavtion. The survival period was longer in hyperfractionated irradiated group particularly if the tumors were located in the posterior portion of brain, however there was no singificant statistics due to small number of patients. Mean survival period for glioblastoma multiforme was 11.8 months in hyperfractionated group vs 8.7 months in conventional fractionated group and for high grade astrocytoma 36month in hyperfractionated group, but in conventional fractionated group all was died in 18 months. Acute radiation reaction occurred less frequently in hyperfractionated group, 15.8% vs 47.8% in conventional fractionated group(p<0.024). Alopeci was developed in 31.6% of the hyperfractionated group vs 82.6% of the conventional fractionated group(p<0.0031). One case of later radiation necrosis in cancer region was suspected in the hyperfractionated group but we has been in a dilemma for confirmatory diagnosis in present available diagnostic technique. The hyperfractionated irradiation technique was proven to be superior to conventional fractionated technique regarding the radiation reaction and the effectiveness of the treatment.

PURPOSE: To evaluate the pathologic effects of preoperative radiotherapy on the resectable distal rectal cancer, we analyzed the results of postoperative pathologic findings for the patients with preoperative radiotherapy and surgery. MATERIALS AND METHODS: From July 1995 to April 1996, we treated sixteen patients of resectable rectal cancer with preoperative radiation therapy and curative surgery. At diagnosis, Thomas Jefferson (TJ) system was used for the clinical stage of the patients. We treated the patients with conventional radiation therapy of 4500-5000cGy before surgery. The surgery was carried out 4 weeks after completion of radiation therapy. Modified Astler Coller (MAC) system was used for the postoperative pathologic stage. We analyzed the pathologic stages and findings according to preoperative clinical stage and compared with those of the control group in similar clinical stages. RESULTS: All patients were treated with sphincter preservation surgery after preoperative radiation therapy. Pathologic complete response (CR) was shown in 1 case (6.3%). We compared the results between preoperative radiation therapy group (Preop.RT group) and surgery only group (control group). In TJ stage II, among nine patients of Preop.RT group, 8 patients (88.9%) were in MAC stage B except 1 CR patient, but among 17 patients of control group, 11 patients (64.7%) were in MAC stage B and 6 patients (35.3%) in MAC stage C. In TJ stage III, among 7 patients of Preop.RT group, 4 patients (57.1%) were in MAC stage B and 3 patients (42.9%) in MAC stage C. Among 14 patients of control group, 4 patients (28.6%) were in MAC stage B and 10 patients (71.4%) in MAC stage C. Above results showed that postoperative pathologic stage was decreased in Preop.RT group with statistical significance (p=0.049). The postoperative pathologic findings (blood vessel invasion, lymphatic vessel invasion, perineural invasion) were decreased in the Preop.RT group compared with those of control group. But statistical significance was found only in lymphatic vessel invasion (p=0.019). CONCLUSION: The postoperative pathologic stages and adverse prognostic pathologic findings were decreased in preoperative radiation therapy group. The lymphatic vessel invasion and MAC stage C findings were abruptly decreased in preoperative radiation therapy group. The preoperative radiation therapy was found to be effective in resectable rectal cancer. The patients group in our study was very small and long term follow up was not done. Therefore, further study about this issues is needed .

PURPOSE: External beam radiotherapy (EBRT) plays a controversial role in the management of differentiated thyroid cancer. We reviewed the outcomes of patients at our institution who had been treated with EBRT for advanced differentiated thyroid cancer. METHODS: Subjects included 35 patients who received thyroidectomy and EBRT at Yonsei University Wonju College of Medicine, Wonju Christian Hospital under the diagnosis of papillary thyroid cancer from January 1989 to September 2011. RESULTS: The 5 year overall locoregional control rate was 74.4%. No significant differences were found in locoregional progression- free survival for patients with complete resection, microscopic residual disease, or gross residual disease. CONCLUSION: The results of our study have shown that EBRT is effective for locoregional control of selected locally advanced papillary thyroid cancer, even with gross residual disease.

The purpose of this pictorial essay is to illustrate the multimodality imaging findings of a wide spectrum of radiation-induced complications of breast cancer in the sequence of occurrence. We have classified radiation-induced complications into three groups based on the time sequence of occurrence. Knowledge of these findings will allow for the early detection of complications as well as the ability to differentiate tumor recurrence.

OBJECTIVETo study the clinical features and proper treatment of 38 elderly patients with early double primary cancers.

METHODSThirty-eight elderly patients with early double primary cancers treated from January 1980 to March 2003 were retrospectively reviewed for involved organs, treatment and prognosis.

RESULTSDigestive tract was the most frequently involved, followed by urogenital system and lung. Long-term results of endoscopic mucosal resection (EMR), operation and radiotherapy were superior to other methods. The prognosis of gastrointestinal carcinoma was better than that of prostate carcinoma and hematopoietic system. The operation rate decreased with increasing age. The 5-year survival rates of EMR, operation and radiotherapy were 85.7%, 71.1% and 75.0%, respectively. The medium survival time was 120 months in first cancer and 39 months in the second primary cancer. The 5-year survival rates of the first cancer and second primary cancer were 88.6% and 53.8%.

CONCLUSIONYearly follow-up for elderly patients with endoscopy, beta ultrasonic scan and X-ray contribute to finding of early double primary cancers. Operation is the best treatment of early double primary cancers. Endoscopic mucosal resection is especially suitable for old patients with digestive tract and bladder cancer.

OBJECTIVETo analyze the clinical features and prognosis of radiotherapy associated sarcoma (RAS) in the head and neck following radiotherapy for nasopharyngeal carcinoma (NPC).

METHODSThe clinicopathologic data, diagnosis, treatment and follow-up results of 11 patients with RAS diagnosed between January 1995 and December 2011 at Zhejiang Cancer Hospital were analyzed retrospectively. Among these patients, 6 were males and 5 were females. Patients' ages ranged from 33 to 66 years (median 50 years). The latency period for development of the RAS was between 3 years and 23 years (median 7 years) after irradiation. Overall survival rate was calculated using the Kaplan-Meier method and Log rank test.

RESULTSAll cases underwent surgery, of them 6 casesachieved radical resection3 cases left with microscopic positive resection margins and 2 caseshad palliative surgery. Among 11 patients, 4 had re-surgery after recurrence, including 1 case had repeated surgeries followed by chemotherapy and radioactive seed implantation. Follow-up time ranged from 2 to 102 months, andeight patients died The 2-year, 3-year and 5-year cumulative survival rateswere 45.5%, 30.3% and 15.2%, respectively. The median survival time was 15 months. Surgical resection with clear margins achieved significantly better prognosis (P = 0.04).

CONCLUSIONSThe incidence of RAS after radiation of NPC is generally low, but the treatment of RAS is very difficult, with poor prognosis.
