A retrospective study of 2060 inpatients with cirrhosis of the liver identified 164 patients with extrahepatic cancer, a 20-fold increase over the expected number. Gastrointestinal, ENT, pulmonary, and hematologic malignancies predominated. Extrahepatic cancers occur more often and at an earlier age in patients with cirrhosis of the liver than in the population at large.

The risk of hepatitis C virus (HCV) transmission to surgeons is related to the HCV prevalence in the surgical patient population. As HCV-related cirrhosis is the commonest indication for liver transplantation in Europe and North America, liver transplant surgeons are at particular risk. The prevalence of HCV infection in liver transplant surgeons is unknown. The aim of this study was to estimate the prevalence of HCV infection in liver transplant surgeons attending the 9th Congress of the International Liver Transplantation Society using unlinked anonymous testing for HCV. Surgeons attending the conference were invited to complete an anonymised questionnaire regarding their surgical and transplant practice and provide an unlinked anonymised blood spot sample by finger prick. Samples were screened for antibodies to HCV (enzyme-linked immunosorbent assay III, Ortho Diagnostics, Raritan, NJ). Polymerase chain reaction testing for HCV RNA was performed on reactive samples.A total of 117 liver transplant surgeons (79 European, 16 North American, 10 Asian, 9 South American, 3 Australasian) provided a blood spot sample. Two (1.7%) surgeons had antibodies to HCV, 1 (0.8%) had detectable HCV RNA (genotype 1a). Assuming that both infections were acquired during surgery, the estimated maximum rate of HCV transmission is 1 per 743 to 1,045 years of surgical (0.96 to 1.35 HCV transmissions per 1,000 years of general surgical practice) and 449 to 683 years of liver transplant practice (1.46 to 2.23 HCV transmissions per 1,000 years of liver transplantation practice). In conclusion, risk of HCV transmission to liver transplant surgeons appears to be low despite the particular risks associated with frequently operating on HCV infected patients.

Parathyroid gland carcinoma is a rare malignancy. The tumor is mostly functioning, causing severe hyperparathyroidism, with high serum calcium level and severe bone disease. Non-functioning parathyroid carcinomas are extremely rare. We report on a 60-year-old male patient admitted to ENT Department due to a large neck tumor mass compressing the thyroid and trachea. Preoperatively, thyroid hormone, parathyroid hormone (PTH) and calcium serum levels were normal. The following immunohistochemical markers (DAKO, Denmark) were used: bcl-2; CD-10; Chromogranin-A; Cyclin-D1; EMA; Ki-67; Mdm-2; p-53; PGP-9,5; RCC; Synaptophysin; Thyroglobulin; and TTF-1. Immunohistochemical analysis indicated the diagnosis of a primary parathyroid gland carcinoma. Tumor cells showed diffusely positive immunohistochemical staining with chromogranin-A and PGP-9,5, positive staining of variable intensity with synaptophysin, and weakly positive reaction with EMA. Also, the cytoplasm of tumor cells was diffusely positively stained with bcl-2, while the nuclei showed positive reaction with p-53 oncogene and TTF-1. The remaining markers (CD-10, cyclin-D1, Ki-67, Mdm-2, RCC and thyroglobulin) were negative. Four years after the surgery, the patient died from renal carcinoma pulmonary metastases and liver cirrhosis complications. In conclusion, non-functioning parathyroid gland carcinoma is a very rare disease. Detailed immunohistochemical analysis is needed to distinguish it from other thyroid and parathyroid neoplasms and metastatic carcinoma. Surgical treatment is presently the best mode of therapy.
