1.Neoadjuvant therapy in pancreatic cancer.
Acta Academiae Medicinae Sinicae 2005;27(5):644-647
Pancreatic cancer remains a major troublesome clinical problem, with conventional cancer treatments having little impact on disease course. The extent of disease is often classified as localized, locally advanced, and metastatic. Radical operation is the most effective method, but only 15%-20% of patients have resectable disease, and around 20% of them survive to 5 years. For locally advanced, unresectable, and metastatic diseases, palliative treatment is more appropriate, but the median survival in these patients is less than 6 months and the 5-year survival rates are even lower than 4%. Neoadjuvant therapy has been gradually accepted in breast cancer and gastroenterological cancer, and its value in pancreatic cancer has attracted increasing interests. This paper reviews recent advances of neoadjuvant therapy in pancreatic cancer.

2.Challenge and Hope in Radiotherapy of Hepatocellular Carcinoma.
Yonsei Medical Journal 2009;50(5):601-612
Hepatocellular carcinoma (HCC) is one of the most critical global health issues. With frequent association of viral liver disease, HCC is highly complex, harboring both cancer and chronic liver disease. The tumor stage and underlying liver function are both major determinants of the treatment selection as well as prognosis in HCC patients, thus allowing no more than a 20% chance for potentially curative therapies. Radiotherapy technology has been evolved remarkably during the past decade, and radiation can be precisely delivered, thereby permitting higher doses to the tumour and reduced doses to surrounding normal tissues. There has been increasing interest in the merits of radiotherapy in HCC over the past few years, as indicated by a Pub Med search. Radiotherapy has been used as the definitive therapy with curative intent in early stage tumours. It has been used also in combination with TACE for intermediate stage tumours. In locally advanced tumours, radiotherapy has been combined with systemic agents. Despite its efficacy, radiotherapy has not yet been incorporated into the standard management guidelines of HCC. The lack of high evidence level data, especially randomized controlled trials, has posed an obstacle in including radiotherapy into the routine treatment schema of HCC. Therefore, well-designed prospective studies are strongly recommended using developing technology for radiotherapy alone or combination therapies. Also, many issues such as the optimal dose-fractionation, intra- or extrahepatic metastasis after radiotherapy, and radiation-induced hepatic dysfunction remain to be solved. In this review, current status of radiotherapy for HCC will be discussed with regard to technical consideration and combination strategy. The limitation and future perspectives will also be discussed.

OBJECTIVETo explore efficacy of neoadjuvant radiochemotherapy in locally advanced low rectal cancer.
METHODSFrom May 2001 to August 2005, 105 patients with locally advanced low rectal cancer (T3, T4) were treated by preoperative radiotherapy to pelvis, 2.0 Gy daily up to 40-46 Gy in 4-5 weeks concomitantly with oral capecitabine at 1250 mg x m(-2) x d(-1) for 10 weeks up to surgery. In all patients surgery was carried out under the rule of total mesorectal excision technique.
RESULTSAll patients finished the course of neoadjuvant radiochemotherapy. Among them, 36 patients experienced adverse effects. Thirteen patients resulted in complete tumor response and spared the operation. Ninety-two patients were operated on with radical resection, among them 71 patients with low anterior resection, 17 with Parks' colo-anal anastomosis and 4 with abdomino-perineal resection, so sphincter preservation was achieved in 96.2%. In postoperative pathological studies, 11 cases showed complete tumor regression. According to the TNM staging system, 24 cases were ranged T0N0, and 23 cases T2N0, 43 cases T3N0, 2 cases T4N0, 5 cases T2N1, 8 cases T3N1; and according to Dworak's tumor regression grading, 5 cases were ranked TGR0, and 18 cases TGR1, 11 cases TGR2, 47 cases TGR3, 24 cases TGR4. Pathologic downstaging was achieved in 78.1%, including complete response (TGR4) and intermediate response (TGR2 + 3). No operative death occurred. Anastomotic leakage was found in 5 cases, including 3 rectovaginal fistula. All patients have been followed up for 16-67 months, and lung metastasis occurred in 4 cases, liver metastasis in 2 patients and local recurrence in 4 patients. Three patients died of distant metastasis. The 3-year disease-free survival was 82.8% and overall survival was 96.5%.
CONCLUSIONSNeoadjuvant radiochemotherapy brings tumor down-staging and increases resectability and sphincter preservation, decreases recurrence and improves survival in locally advanced low rectal cancer.

OBJECTIVETo summarize the experiences in gallbladder cancer treatment, evaluate the efficacy of postoperative radiotherapy, and investigate the method of improving the survival of gallbladder cancer patients.
METHODSOne hundred and twenty-seven gallbladder cancer patients, treated in our center by radical resection (84 cases) and combined with postoperative radiotherapy (43 cases), between June 2003 to December 2009 were included in this study. Their clinical data and follow-up results were retrospectively analyzed. According to AJCC staging criteria, the survival time and 1-, 3- and 5-year survival rates of the surgery group and the postoperative radiotherapy group at the different pathological stages and resection margin status were compared.
RESULTSThe median survival time of postoperative radiotherapy patients in stage III was 16.9 months, and the 1-year, 3-year, and 5-year survival rates were 55.7%, 23.5% and 18.2%, respectively, significantly higher than that of the simple operation group ( median survival time 14.3 months, and 1-year, 3-year, 5-year survival rates 42.7%, 22.6% and 16.7%, respectively) (P<0.05). The median survival time of postoperative radiotherapy patients in stage IV, the median survival time was 9.7 months in the postoperative radiotherapy group and 6.3 months in the simple surgery group, and the 1-year survival rates were 14.2% and 9.8%, the 3-year survival rates were 7.2% and 3.9%, the 5-year survival rates were 7.2% and 1.9%, respectively, all showing a statistically significant difference (P<0.05). Among the stage III and IVpatients, all the 1-, 3- and 5-year survival rates of the postoperative radiotherapy group were higher than that of the simple R0 and R1 surgical resection group (all P<0.05), but with a non-significant difference between the stageIandIIpatients (P>0.05). The main side effects in postoperative radiotherapy patients including nausea, vomiting and abdominal pain, all were successfully alleviated by symptomatic and supportive therapy, and the radiotherapy was successfully completed.
CONCLUSIONSWith regard to the gallbladder cancer patients in stage III and IV, the survival rate can be obviously increased by postoperative radiotherapy. However, for patients in stageIand II, whether postoperative radiotherapy significantly improves the survival or not, needs to be further validated in larger scale studies.

OBJECTIVETo investigate the effect of enterostomy in treatment of locally advanced rectal carcinoma patients with combined chemoradiotherapy and operation.
METHODSClinical data from 51 cases of locally advanced rectal cancer patients treated with preoperative chemoradiotherapy and operation were analyzed.
RESULTSThirty-three patients (64.9%) got staging down of their cancer after preoperative chemoradiotherapy, and 21.6% of patients (11 cases) had complete pathologic response. Thirty-seven patients received enterostomy, including extraperitoneal sigmoidostomy (29 cases), defunctioning ileostomy (8 cases) and double colostomy (3 cases with colon obstruction during preoperative therapy). One case experienced parastomal hernia and one stomal stenosis and 2 cases parastomal infection after enterostomy. No death of enterostomy occurred.
CONCLUSIONColostomy can reduce the pressure of obstructed intestinal tract and contribute much to the preoperative chemoradiotherapy, ileostomy can protect the distal stoma from leakage in sphincter saving operation. Enterostomy could be selected when needed in the favor of locally advanced rectal cancer patients.

OBJECTIVETo analyze the causes and therapeutic approaches for the complications of radical hysterectomy plus pelvic lymphadenectomy in cervical cancer patients.
METHODSFrom Jan. 1995 to Dec. 2003, 219 such patients were treated by radical hysterectomy plus pelvic lymphadenectomy. The stages were: 26 stage IA (17 stage IA1 and 9 stage IA2) (11.9%); 142 stage IB (78 stage IB1, 64 stage IB2) (64.8%); 40 stage IIA (18.3%) and 3 stage IIB (1.4%). 204 patients in this series were treated by radical hysterectomy plus pelvic lymphadenectomy and 15 by modified radical hysterectomy with pelvic lymphadenectomy.
RESULTSa total of 49 patients (22.4%) developed postoperative complications. The major complications included: bladder dysfunction (10.0%); formation of lymphocysts (7.8%); wound infection (6.8%); hydronephrosis (1.4%) and formation of ureteral fistulas (0.5%). The patients in the group treated by radical hysterectomy plus pelvic lymphadenectomy was likely to develop postoperative complication compared with the patients in the group by modified radical hysterectomy plus pelvic lymphadenectomy (24.0% versus 0, P = 0.067). The postoperative complication incidence in the patients who had preoperative neoadjuvant chemotherapy through intra-arterial catheter or radical radiotherapy in the other hospitals were 50.0% (2/4) and 100.0% (1/1), which were higher than that of the patients treated primarily in our hospital (21.3%, 25.3%) though without statistically significant difference among the groups. Of 52 patients who had previous abdominal surgery history, 13 developed posoperative complications, there was no significant difference between the patients with or without previous abdominal surgery history. The complication incidence of 87 patients treated with preoperative afterloaded radiotherapy was higher than that of 124 patients primarily treated by surgery (25.3% versus 19.4%), but the difference between two groups was statistically not significant (P = 0.239).
CONCLUSIONThe complication of radical hysterectomy with pelvic lymphadenectomy is correlated with the surgery mode. Preoperative afterloaded radiotherapy may not increase postoperative complication incidence. Properly reducing the extent of surgery may decrease incidence of complications.

OBJECTIVETo investigate the association between survival and postoperative three-dimensional conformal radiotherapy (3DCRT) in patients with resected non-small cell lung cancer (NSCLC).
METHODSEighty-four patients were treated with surgery and postoperative 3DCRT for NSCLC. Sixty-five (77.4%) patients received lobectomy, and 19 (22.6%) received pneumonectomy. Fifty-four (64.3%) patients achieved R0 resection and 30 cases (35.8%) received R1/R2 resection. Fifty-two patients were of stage IIIA and 24 patients were of stage IIIB. Photon energy of 6 MV was used for all the patients. The median 3DCRT dose was 60 Gy (40 - 70 Gy) with a fraction size of 2 Gy. Thirty-seven patients received median 3 cycles of adjuvant chemotherapy. The median follow-up was 35.5 months for survivors.
RESULTSThe overall 3-year survival rate was 58.6%, and the 4-year overall survival rate was 43.9%. Of the 43 patients who had treatment failure, only 8 (9.9%) patients showed intrathoracic recurrence, but 38 (46.9%) patients had distant metastasis. The univariate analysis for all patients showed that sex, age, weight loss, tumor size, pathology and stage were not correlated with prognosis. R1/R2 resection was associated with a significantly worse survival. Toxicities were acceptable, with 9 (11.1%) patients appeared higher than NCI CTC grade 2 radiation pneumonitis.
CONCLUSIONIn a population-based cohort, postoperative 3DCRT for NSCLC provides a good prognosis, and the radiation-related pneumonitis is acceptable.

OBJECTIVETo explore the diagnosis and operative treatment of radiation-induced brachial plexopathy.
METHODSNine cases of radiation-induced brachial plexopathy were divided into two groups, 4 cases undergoing neurolysis of brachial plexus as Group A and 5 cases undergoing transfer of myocutaneous flaps after neurolysis as Group B. In Group B, 4 cases were treated with latissimus dorsi myocutaneous flaps (about 20 cm x 20 cm) and 1 case with pectoralis major myocutaneous flap (about 8 cm x 6 cm).
RESULTSAll the 9 cases of radiation-induced brachial plexopathy were followed up for a period of 2 to 5 years, with an average of 2.3 years. As far as pain relief and function recovery were concerned, the results of Group B were better than those of Group A.
CONCLUSIONSBased on the results of Group B in the series, we suggest that the procedure of covering the wounds with transferred myocutaneous flaps after neurolysis of the brachial plexus should be performed to those advanced patients. The procedure may improve the blood supply of the fibrotic brachial plexus by reestablishing a good nerve bed.

BACKGROUND: The long-term survival of patients with non-Hodgkin's lymphoma after conventional chemotherapy is about 35%, with the remaining 65% of patients tending to be refractory or experience relapse. As such, primary refractory patients responding to salvage chemotherapy, and sensitive relapsed patients and primary high- risk patients are recommended to receive high-dose chemotherapy (HDC) and autologous peripheral blood stem cell transplantation (PBSCT). We evaluated the role of HDC and autologous PBSCT in patients with primary refractory, primary high risk, and sensitive relapsed non-Hodgkin's lymphoma. METHODS: We performed a retrospective analysis of the data from 50 patients with non-Hodgkin's lymphoma who were treated with HDC and autologous PBSCT in the Catholic Hematopoietic Stem Cell Transplantation Center between 1997 and 2002. RESULTS: Of the 50 patients, the conditioning regimen was BEAM in 20, CMT (cyclophosphamide, melphalan and thiotepa) in 19, fludarabine- and total body irradiation (TBI) -based regimen in 8, and cyclophosphamide and TBI in 2. There were 3 (6%) deaths due to treatment-related toxicity within the first 50 days after transplantation. Twenty-five patients remain alive at a median follow-up duration of 40.5 months (range 9~61). Among the patients with partial response before transplantation, 76% showed further response after transplantation. In half of these responders, the disease state was changed into complete response (CR) after transplantation. 2-year overall survival was 52% and 2-year progression free survival was 36.8%. Median overall survival was 34 months (range 8~60), and median progression-free survival was 8 months (range 1~14). Median overall survival was 14 months (range 9~19) in the primary high-risk group (n=13), 7 months (range 4~10) in the resistance relapse group (n=5), and 6 months (range 0~14) in the primary refractory group (n=10). Overall survival in the sensitive relapse group (n=22) did not reach the median; the mean overall survival in this group was 33 months. The disease status before transplantation was the only significant prognostic factor in determining overall survival (p=0.032) and progression- free survival (p=0.001). CONCLUSION: HDC and autologous PBSCT appears to produce high response rate. Primary high-risk group and sensitive relapse group had good prognosis, while refractory and resistance relapse group had poor prognosis. And the pre-transplantation disease status was the only significant prognostic factor in multivariate analysis.
