1/238. pancreaticoduodenectomy for metastatic tumors to the periampullary region.

    Although operative resection of metastatic lesions to the liver, lung, and brain has proved to be useful, only recently have there been a few reports of pancreaticoduodenectomies in selected cases of metastases to the periampullary region. In this report we present four cases of proven metastatic disease to the periampullary region in which the lesions were treated by pancreaticoduodenectomy. Metastatic tumors corresponded to a melanoma of unknown primary site, choriocarcinoma, high-grade liposarcoma of the leg, and a small cell cancer of the lung. All four patients survived the operation and had no major complications. Two patients died of recurrence of their tumors, 6 and 63 months, respectively, after operation; the other two patients are alive 21 and 12 months, respectively, after operation. It can be inferred from this small but documented experience, as well as a review of the literature, that pancreaticoduodenectomy for metastatic disease can be considered in selected patients, as long as this operation is performed by experienced surgeons who have achieved minimal or no morbidity and mortality with it.

3/238. Case report: clostridium septicum infection presenting as liver abscess in a case of choriocarcinoma with liver metastasis.

    clostridium septicum is an anaerobic, gram-positive bacillus. infection with this organism has a known association with malignant diseases, especially colon and haematological cancers. clostridium septicum is rarely found to be a pathogen of liver abscess. Herein, we report the case of a female choriocarcinoma patient with liver metastasis in which C. septicum infection presented as a gas-forming liver abscess. This case and previous reports indicate that once C. septicum is identified as a pathogen in liver abscess, metastatic liver tumours should be highly suspected.

4/238. carcinosarcoma of the uterus associated with a nongestational choriocarcinoma.

    choriocarcinoma has been reported in association with endometrial carcinoma and as a metaplastic change in multiple carcinomas, including liver, urinary bladder, lung, and the gastrointestinal tract. We report choriocarcinoma in conjunction with a carcinosarcoma (also called malignant mullerian mixed tumor) in a 71-year-old woman whose hysterectomy specimen revealed two polypoid lesions of the endometrium, one arising from the anterior endometrium and one arising from the posterior endometrium. Histologic examination revealed three histologic patterns. The anterior endometrial lesion showed a FIGO grade 2 endometrioid endometrial adenocarcinoma. The posterior endometrial lesion showed a carcinosarcoma composed of a high-grade adenocarcinoma and scant homologous stromal sarcoma. In addition, a choriocarcinoma was identified intermixed with the adenocarcinoma. The syncytiocytotrophoblasts and cytotrophoblasts stained strongly with 0 human chorionic gonadotropin (beta-hCG) and human placental lactogen (hPL). The patient's beta-hCG levels on postoperative days 14, 27, and 42 were 283, 32, and 7 mIU/mL, respectively. This unusual case suggests the importance of identifying the choriocarcinomatous component, since the serum beta-hCG can serve as a marker of tumor recurrence postoperatively.

5/238. Ocular metastasis of choriocarcinoma.

    Metastatic tumours of the eye commonly occur from primaries of the breast or lung. The prognosis is poor and the mean life expectancy is 6.5 months from diagnosis. Although metastatic tumours of the eye are not a rarity, ocular metastasis from choriocarcinoma has not been reported previously. We report a case of gestational choriocarcinoma with ocular metastasis.

6/238. False diagnosis and needless therapy of presumed malignant disease in women with false-positive human chorionic gonadotropin concentrations.

    BACKGROUND: 12 women were diagnosed of having postgestational choriocarcinoma on the basis of persistently positive human chorionic gonadotropin (hCG) test results in the absence of pregnancy. Most of the women had extirpative surgery or chemotherapy, or both, without significant diminution in hCG titre. Our aim was to assess whether the hCG concentrations were false-positive test results. methods: Samples were tested for hCG, hCG free beta subunit, and hCG beta-core fragment. Assay kinetics were also assessed, and samples were tested independently by competitive RIA. False-positive hCG concentrations were identified by two criteria: detection of hCG in serum and lack of detection of hCG and its degradation products in urine; and wide variations in results for different hCG assays. We corroborated false-positive hCG values by the lack of parallel changes in hCG results when serum was diluted, by false detection of other antigens, and by failure to detect hCG with in-house assays. FINDINGS: All 12 women met both criteria for false-positive hCG, and all had corroborating findings. In all 12 cases, a false diagnosis had been made, and most of the women had been subjected to needless surgery or chemotherapy. Assay kinetics indicated that heterophilic antibodies were responsible for the false-positive results. As a result of our findings all further therapy was stopped. INTERPRETATION: Current protocols for the diagnosis and treatment of choriocarcinoma should be modified to include a compulsory test for hCG in urine.

7/238. An unusual case of choriocarcinoma following live term pregnancy.

    Post-term choriocarcinoma is an infrequent event with poor prognosis. The diagnosis is usually delayed due to failure to recognise the mode of presentation of this disease. Being a rare occurrence, limited data is available regarding its clinical features. The choriocarcinoma in our patient presented as an isolated huge pedunculated growth over the uterine serosa without intrauterine involvement and distant metastasis.

8/238. choriocarcinoma and partial hydatidiform moles.

    BACKGROUND: Partial hydatidiform moles (PMs) rarely require chemotherapy and have never previously been proven to transform into choriocarcinoma, the most malignant form of gestational trophoblastic disease (GTD). Consequently, some have questioned whether women with PMs need human chorionic gonadotropin (hCG) follow-up. Here, we investigate whether PMs can transform into choriocarcinomas. methods: patients with a PM who developed a subsequent choriocarcinoma were identified from our GTD database. The histology of both PM and ensuing choriocarcinoma was reviewed and flow cytometry used to verify the triploid status of the PMs. To determine whether the choriocarcinoma arose from the PM, dna from the PM and choriocarcinoma in each patient was compared using microsatellite polymorphisms. FINDINGS: Of the 3000 patients with PM, 15 required chemotherapy for persisting GTD. This was identified as choriocarcinoma in three cases. In one patient, the local pathologist could not differentiate between a PM or a hydropic abortion and neither central histological review nor hCG follow-up were obtained. This patient nearly died before the diagnosis of choriocarcinoma was made. Fortunately, the local pathologists correctly diagnosed PM in the two other patients who were then registered for hCG follow-up. Some months later, the hCG was rising and repeat uterine evacuation revealed choriocarcinoma. The PM was confirmed to be triploid in all three cases and genetic analysis showed that the subsequent choriocarcinomas contained identical single maternal and two paternal alleles at several independent loci. INTERPRETATION: Our results show that PMs can transform into choriocarcinoma. All patients with suspected PM should be reviewed centrally and, if confirmed, need hCG follow-up.

9/238. Primary choriocarcinoma of the ovary. Report of two cases.

    Primary choriocarcinoma of the ovary (PCO) is rare. This can be gestational (GCO) or nongestational (NGCO) in origin. It is difficult to differentiate between CGO and NGCO. NGCO carries a worse prognosis than GCO. We present two cases of metastatic GCO who were treated successfully with combination chemotherapy and are alive and disease free at the time of reporting.

10/238. A case of pulmonary tumour embolism mimicking miliary tuberculosis.

    Pulmonary metastases from choriocarcinoma can very rarely give rise to a 'miliary' pattern on the chest X-ray. A 23-year-old woman with a diffuse nodular pattern on chest X-ray died due to acute respiratory failure and cor pulmonale. At autopsy, choriocarcinoma of the uterus was found. In the lungs, multiple macrovascular tumour emboli within branches of pulmonary muscular arteries in the region of segmental/subsegmental bronchi were detected. There was no evidence of pulmonary parenchymal metastases, pneumonia or tuberculosis. The 'miliary' pattern of pulmonary metastases described in cases of choriocarcinoma may be due to large vessel intra-arterial tumour emboli rather than disseminated parenchymal metastases.
