For the purpose of enhancing the therapeutic index and reducing the toxic effect of chemotherapeutic drugs, Dau-HA-Ms was prepared, mostly as monodispersed microspheres with a mean diameter of 52 +/- 16 microns, ranging from 29 to 194 microns, being suitable for the use of transarterial embolization (TAE) therapy. Dau released effectively in physiological saline solution from microspheres without burst release. The spectrophotometric characteristics and cytotoxic effect in vitro of the released Dau remained unchanged, retaining the original physicochemical and biological properties. It was demonstrated that 30% of mice bearing S-180 sarcoma ascites treated with intraperitoneal injection of Dau-HA-MS survived longer than 6 months, while all tumor bearing control mice and Dau treated tumor bearing mice died within 21 and 14 days, respectively. The results show that Dau-HA-MS is therapeutically more effective and less toxic than Dau, Dau-HA-MS can possibly be used in TAE therapy for human liver cancer.

Transplantable rat tumours (sarcoma M-1, sarcoma 45, alveolar liver cancer PC-1 and Pliss' lymphosarcoma) were used to study chlorin e6 accumulation in tumours and its photodynamic effect. Tumours were irradiated by krypton ion laser light (647 and 676 nm; 90 J cm-2) 15 min and 24 h after chlorin e6 injection at doses of 5 and 10 mg kg-1. The relationship between some morphological peculiarities of these tumour strains, photosensitizer accumulation in tumours and their response to the photodynamic treatment is discussed.

Liver cancer is an uncommon indication for liver transplantation in children. Between 1986 and 1995, five children with hepatocellular cancer (HCC), three with hepatoblastoma (HEP), and one with sarcoma were referred to the transplant service. All nine tumors were considered unresectable. Four of the five children with HCC had underlying predisposing conditions (2 hepatitis B, 1 biliary atresia, 1 tyrosinemia). Preoperative evaluation of all patients included careful radiological screening and pretransplantation laparotomy for staging. Two patients with HCC were excluded from further consideration because of intraabdominal spread. Three patients had transplantation (mean age, 6.0 +/- 7.1 years), and all have survived for 1 to 5 years with no evidence of recurrence. Three patients with HEP were assessed (mean age 2.0 +/- 1 years); two had stage 4 disease and one had stage 3. All three received preoperative chemotherapy. The two with stage 4 had thoracotomies as part of their assessment. Two of three patients had a significant decrease in the size of the primary tumor during the waiting period. These two patients and one with stage 4 disease have survived more than 2 years since transplantation, with no recurrence. The third patient had recurrence within 2 months of transplantation. In summary, liver transplantation should be considered for all children who have unresectable hepatic malignancies, given the 83% survival rate and no evidence of tumor recurrence. Stage 4 disease in HEP does not necessarily exclude patients from transplantation. Early referral is encouraged so that tumor spread beyond the liver is minimized.

A study was undertaken to estimate the magnitude of association between self-reported infectious mononucleosis (IM) and 6 types of cancer, including Hodgkin's disease, non-Hodgkin's lymphoma, nasopharyngeal cancer, nasal cancer, primary liver cancer, and sarcoma. Cases were male, aged 15-39 y in 1968, who lived in 8 cancer registry areas. Controls were men selected by random-digit telephone dialing. Cases included 1511 persons with non-Hodgkin's lymphoma, 343 with Hodgkin's disease, 386 with sarcoma and 168, 113 and 70 with primary liver, nasopharyngeal and nasal cancers, respectively. There were 1910 controls. For the 6 cancers combined, the overall odds ratio for IM occurring < 5 and > or = 5 y of the reference date were 5.40 [95% (Confidence Interval (CI) = 1.61, 18.09] and 1.08 (0.84, 1.40), respectively. Analogous values were 4.59 (1.25, 16.85) and 1.07 (0.78, 1.48) for non-Hodgkin's lymphoma and 7.49 (1.52, 36.92) and 1.35 (0.87, 2.09) for Hodgkin's disease. There was the suggestion of a protective association with IM occurring > or = 5 y before cancer onset for the 4 non-lymphomatous cancers. Strongly positive associations between self-reported IM and 6 types of cancer were observed for IM occurring < 5 y before the onset of cancer. There was a suggestion, which is noted with extreme caution, that IM earlier in life might have had a protective association with the 4 non-lymphomatous cancers.

The German Thorotrast study comprises 2,326 patients and 1,890 controls. Forty-eight Thorotrast patients and 239 controls are still alive and are invited for a follow-up examination every 2 years. In the deceased patients, the following neoplastic diseases with excess rates were registered (Thorotrast/controls): liver cancer (454/3); cancer of the bile ducts, including gallbladder (42/7); myeloid leukemia (40/7); myelodysplastic syndrome (30/4); plasmacytoma (10/2); non-Hodgkin's lymphoma (15/5); bone sarcoma (4/1); malignant peritoneal or pleural mesothelioma (9/0). Dose calculations are based on results of whole-body counting, X-ray films, and data obtained from the hospital records on the volume of Thorotrast injected. For liver cancer, the cumulative risk estimate was calculated to be 40 per 10(4) person Sv (radiation weighting factor = 20). These figures are close to the results of the Danish study and are comparable to the results of the Life Span Study of A-bomb survivors after 40 years at risk with 18 to 48 liver cancers per 10(4) person Sv. For hematopoietic malignancies, the cumulative risk was calculated to be about 7 per 10(4) person Sv (radiation weighting factor = 20). This risk estimate is lower by a factor of 10 compared to the results of the Life Span Study.

The purpose of this study was to investigate the pathologic changes of extracorporeal ablation of human malignant tumors with high-intensity focused ultrasound (HIFU). HIFU treatment was performed in the 164 patients with liver cancer, breast cancer, malignant bone tumor, soft tissue sarcoma and other malignant tumors at focal peak intensities from 5000 W x cm(-2) to 20,000 W x cm(-2), with operating frequencies of 0.8 to 3.2 MHz. To explore the pathologic impact of extracorporeal HIFU, 30 patients with malignant carcinoma underwent surgical removal after HIFU treatment. Pathologic findings showed that the treated tissues demonstrated homogeneous coagulative necrosis with an irreversible tumor cell death and severe damage to tumor blood vessels at the level of microsvasculature within the HIFU-targeted region. Thermolesions to intervening tissue were never observed. The treated region had a sharp border comprising only several cell layers between the treated and untreated areas. The repair of lesions had the processes of necrotic tissue absorption and granulation tissue replacement. It is concluded that extracorporeal treatment of human solid malignancies with HIFU could be safe, effective and feasible. As a noninvasive therapy, HIFU would be used clinically to treat patients with solid malignancies.

Occupational exposure to vinyl chloride (VC) is causally related to liver angiosarcoma, whereas there is inconsistent epidemiologic evidence for other neoplasms. Two pooled analyses of worker cohorts from 56 plants in North America and Europe provide the most comprehensive and updated data on cancer risk among workers exposed to VC. These included over 22,000 workers, with a total of 640,000 person-years of observation, followed-up for up to 50 years. Overall, a total of 1,778 cancer deaths were observed versus 1,829.46 expected, corresponding to a standardized mortality ratio (SMR) of 0.97 (95% confidence interval (CI)=0.93-1.02). Excluding 71 confirmed angiosarcomas, there were 60 deaths from liver cancers versus 44.35 expected (SMR=1.35, 95% CI=1.03-1.74). Lung and laryngeal cancer mortality were significantly lower than expected (SMR=0.88 and 0.59, respectively). The SMRs for soft tissue sarcoma, brain, lymphoid and haematopoietic system cancers were not materially different from unity. Thus, the aggregate data from over 20,000 VC workers in North America and Europe exclude any excess mortality from lung, laryngeal, soft tissue sarcoma, brain, lymphoid and haematopoietic neoplasms. There appears to be a slight excess of liver cancer other than angiosarcoma, which is difficult to interpret and is likely due to residual misclassification of angiosarcomas.

We used the nation-wide Swedish Family-Cancer Database to examine the familial risks of histology-specific bone cancers in offspring by parental or sibling probands. Adjusted standardised incidence ratios (SIRs) were used to measure the risk. Among the 1327 offspring bone cancers, only two parent-offspring pairs and one sibling pair were noted with concordant bone cancer but the SIRs were not significant. Significant associations were observed in specific histological types or specific age groups, some of which may be chance findings arising from multiple comparisons. However, the risk of early-onset (< 25 years) osteosarcoma in offspring was significantly increased when mothers presented with breast cancer (1.7) and melanoma (2.9), suggesting that Li-Fraumeni syndrome could partly explain this familial aggregation. Other associations, such as childhood osteosarcoma with parental liver cancer, Ewing's sarcoma with kidney cancer and giant cell sarcoma with maternal breast cancer, were novel findings and may be related to other familial diseases.

A series of novel methylthio-, sulfinyl-, and sulfonyl-8H-thieno[2,3-b]pyrrolizin-8-oximino derivatives 7A-12P was designed and synthesized as anti-tumor agents. Their structures were confirmed by IR, (1)H-NMR, MS, and elemental analysis. The anti-tumor activities of all the target compounds were tested by the MTT method in vitro against Bel-7402 (human liver cancer) and HT-1080 (human fibro sarcoma) cell lines. Among them, compound 11N (IC(50) = 18.2 microM, 8.2 microM), was the most promising compound of all synthesized molecules, it was 2.5- and 3.3-times more active than cisplatin (IC(50) = 45.2 microM, 26.7 microM), respectively.

The patient was a 79-year-old male. In December 2002, US findings suggested hepatocellular carcinoma, and he was admitted. Liver biopsy led to a diagnosis of well-differentiated hepatocellular carcinoma. Radio frequency ablation (RFA) was performed. Then, regional relapse was detected, and treatment was repeated. However, follow-up with periodic imaging was continued based on the patient's wishes. RFA was completed in December 2005, and TAI in February 2006. In December 2007, abdominal swelling occurred. CT revealed pleural effusion/ascites and nodular tumor in the adipose tissue of the parietal peritoneum and mesentery around the liver. The patient died due to rapid deterioration. Autopsy revealed a tumor involving the liver surface to the peritoneum, suggesting cancerous peritonitis. Histopathologically, liver cancer showed sarcoma-like changes, directly infiltrating the liver surface to the peritoneum. Hepatocellular carcinoma with sarcoma-like changes and peritoneal dissemination is rare. In the present case, it was possible to compare imaging changes with autopsy findings. We report this patient and review the literature.
