OBJECTIVETo evaluate the role of lung lobectomy in the patients of tumor with lung metastases.
METHODSA total of 45 cases of trophoblastic tumor with pulmonary metastases treated by lung lobectomy from 1985-2002 at PUMC hospital was retrospectively analyzed. Seven cases were diagnosed as invasive mole and thirty-eight as choriocarcinoma.
RESULTSLung lobectomy was performed in all of these patients after several courses of chemotherapy. Seven cases of invasive mole reached complete remission. Eleven cases of choriocarcinoma with stage IIIa had received average 13 courses of chemotherapy, 10 of them reached complete remission. Seventeen cases of choriocarcinoma with stage IIIb had received average 14.3 courses of chemotherapy, 11 of them reached complete remission. Ten cases of choriocarcinoma with stage IV had received average 15 courses of chemotherapy, six of them reached complete remission. In the 45 patients, histologic examination disclosed haemorrhagic necrotic tissue in 27 patients, 17 of them reached complete remission (63%). Histologic examination also revealed fibrosis around the focus in 16 patients, 14 of them reached complete remission (88%). Tuberculosis was found in 2 patients.
CONCLUSIONSAlthough the development of effective chemotherapy has resulted in improved survival of patients with gestational trophoblastic tumor, lung lobectomy remains an important adjunct treatment in a selected subset of patients. Pathological examinations can help to estimate the prognosis.

OBJECTIVETo discuss the clinical features and treatment options for aggressive angiomyxoma (AAM).
METHODSWe retrospectively analyzed the clinical data of 4 patients with AAM treated at PUMC Hospital from January 1990 to December 2004.
RESULTSThere were 1 man and 3 women with an average age of 34 years. The average age of the female patients were 27 years. Two patients (50%) had urinary or enteric compressive complaints, while another 2 patients had no clinical symptoms. Two patients underwent transvaginal surgeries, 1 patient underwent transabdomenal surgery, and 1 patient underwent subcurtaneouly local excision. Three patients (75%) experienced recurrences after operation and the median relapse time was 2.5 years.
CONCLUSIONSAAM usually occurs in female pelvic cavity and the soft tissues of female perineum. AAM is huge in capacity, and easy to infiltrate or recur locally.

OBJECTIVETo determine the parental origin of the genome in the molar pregnancies of two familes with familial recurrent hydatidiform mole (FRHM) and to investigate whether the gene responsible for FRHM is likely to be located within the 19q13.4 region in these familes.
METHODSThe features of complete hydatidiform mole (CHM) were confirmed by pathological examination. DNA of CHM was prepared from sections of formalin-fixed paraffin-embedded blocks of molar tissue following laser capture microdissection. The polymerace chain reaction was used to amplify microsatellite polymorphisms in DNA from the patients, their husbands and the captured molar tissue. Parental contributions to the molar tissue were determined using ABI 310 GeneScan software. Genotyping and haplotype analysis of the candidate region on 19q13.4 was performed for members of both families using 25 microsatellite markers.
RESULTSOne CHM from each family was identified as a biparental complete hydatidiform mole. All patients were heterozygous for most of the markers in the chromosome region of interest. In addition the two affected sisters in one of the families had different genotypes for the 19q13.4 region, suggesting that mutations in a different locus might be responsible for the disorder in this family.
CONCLUSIONThe location of the gene responsible for FRHM is unlikely to be located in the 19q13.4 chromosomal region in these two families suggesting that FRHM shows genetic heterogeneity.

BACKGROUNDRespiratory failure caused by metastatic pulmonary choriocarcinoma usually develops rapidly and is associated with a high mortality. The clinical management strategy is important in choriocarcinoma patients with acute respiratory failure. The objective of this study was to evaluate the clinical characteristics, treatment outcome and potential risk factors in patients with acute respiratory failure from metastatic pulmonary choriocarcinoma.
METHODSSixteen patients with acute respiratory failure from pulmonary metastases choriocarcinoma were enrolled and treated at Peking Union Medical College Hospital from 1995 to 2010. Clinical characteristics, causes of pulmonary failure, treatment profiles and outcomes were analyzed retrospectively.
RESULTSThe presence of respiratory infection or hemorrhage was associated with acute respiratory failure in patients with metastatic choriocarcinoma. Fifteen (93.8%) patients presented with pulmonary infection, 8 (50.0%) patients with pulmonary hemorrhage. All patients were treated with face mask or mechanical ventilation. Fourteen (87.5%) patients received initial chemotherapy at a low dosage or with modified regimens, with a median of 2 cycles (range 1 to 4). Seven patients achieved a complete remission (CR), two had a partial remission. Six CR patients remained alive with a median follow-up of 59 months (range 16 to 120). Seven patients developed progressive diseases and subsequently died.
CONCLUSIONSRespiratory infection and hemorrhage were associated with acute respiratory failure in metastatic pulmonary choriocarcinoma. The initial administration of gentle chemotherapy regimens, accompanied with mechanical ventilation, is feasible and effective in attenuating respiratory failure in patients with metastatic pulmonary choriocarcinoma.

OBJECTIVETo investigate the expression of MAGE-B genes in hepatocellular carcinoma (HCC) in order to find new targets for immunotherapy.
METHODSThe expression of MAGE-B1, B2, A1 and A3 mRNA was detected using RT-PCR in HCC tissues and the corresponding adjacent non-HCC tissues from 47 HCC patients, 30 samples of cirrhosis and normal liver tissues. Four samples selected randomly from MAGE-B1 or B2 with positive RT-PCR results were sequenced to confirm the results of RT-PCR. The relationship between the expression of MAGE-B and some clinicopathological parameters was analyzed.
RESULTSMAGE-B1 mRNA and MAGE-B2 mRNA were detected in 44.7% (21/47) and 61.7% (29/47) of HCC samples, respectively, while neither MAGE-B1 nor MAGE-B2 could be detected in the corresponding adjacent non-HCC liver tissues. In addition, none of 30 samples of cirrhosis and normal liver tissues was shown to express both MAGE-B genes. The DNA sequence confirmed that the RT-PCR products were truly target cDNA. The frequency of the expression of MAGE-A1 and A3 was 74.5% (35/47) and 44.7% (21/47), respectively. There was significant correlation between the expression of MAGE-B and MAGE-A (P < 0.05). However, the positive expression of MAGE-B was observed in 5 out of 12 HCC tissues without expression of MAGE-A1 and/or A3. When all four MAGE genes were examined, the positive rate of expression of one, two, three and four genes was 83.0% (39/47), 55.3% (26/47), 48.9% (23/47), and 38.3% (18/47) of 47 HCC tissues, respectively. No correlation was found between the expression of MAGE-B and clinical parameters such as age, sex, tumor size, degree of tumor differentiation, serum alpha-fetoprotein level and hepatitis B virus or hepatitis C virus infection (P > 0.05).
CONCLUSIONMAGE-B genes are expressed with relatively high frequency and specificity in HCC. Most HCC patients with positive expression of at least one member of MAGE-B or MAGE-A gene family are adequate candidates to receive specific immunotherapy. Frequent co-expression of multiple members of MAGE-B and MAGE-A subfamilies provides the possibility of using polyvalent vaccines to achieve more effective immunotherapeutic results.

OBJECTIVETo investigate the expression of four hepatocellular cancer antigen (HCA) gene mRNA in hepatocellular carcinoma.
METHODSThe expression of HCA90, HCA519, HCA520, HCA587 mRNA was detected using RT-PCR in HCC tissues and the corresponding adjacent non-HCC tissues from 46 HCC patients, cirrhosis tissues from 10 samples and normal liver tissues from 10 samples. The relationship between positive expression rate of HCA gene and clinical and lab data was evaluated.
RESULTSOf 46 HCC tissues, HCA90, HCA519, HCA520 and HCA587 mRNA were detectable in 65.2%, 76.1%, 45.7% and 32.6%, respectively. At least one HCA gene mRNA was positive in 82.6% of HCC tissues. Only weak expression of HCA519 could be detectable in 6.5% of the corresponding adjacent non-HCC tissues. None of 10 samples of cirrhosis and normal liver tissues expressed any HCA gene mRNA. No correlation was found between the expression of HCA and clinical date such as age, sex, tumor size, tumor differentiation, serum alpha-fetoprotein level and hepatitis B virus infection or hepatitis C virus infection (P > 0.05). However, in some patients with normal serum alpha-fetoprotein (< 25 ng/L), specific expression of HCA genes was observed.
CONCLUSIONHCA gene mRNA is expressed with a high percentage and specificity in hepatocellular carcinomas and their products are new potential promising targets for immunotherapy of HCC.
