In a consecutive series of 317 patients with hepatocellular carcinoma (HCC), 32 (10.1%) had 35 extrahepatic primary malignant neoplasms (PMNs) (3 patients had triple cancers). Twenty-five PMNs occurred before the diagnosis of HCC, 7 were synchronous and 3 metachronous. These 35 PMNs were: 6 cancers of the colon, 3 of the stomach, 1 of the rectum, 4 of the breast, 2 of the lung, 1 of the larynx, 3 of the prostate, 1 of the penis, 1 of the urinary bladder, 1 of the uterus, 2 of the skin, and the remaining 10 were immunoproliferative cancers, all of B cell origin (7 non-Hodgkin's lymphoma, 2 multiple myeloma, and 1 chronic lymphocytic leukemia). Thus, in this series, B-lymphocyte-derived neoplasms were the most frequent PMNs associated with HCC. These 10 patients showed no difference for age, male:female ratio, HCC cytotype, presence of cirrhosis, alcohol abuse, markers related to hepatitis B and C virus, and serum level of alpha-fetoprotein when compared with the 22 patients with HCC and other PMNs and the 285 with HCC alone. B cell neoplasms constitute half of the synchronous or metachronous cancers, and must, therefore, be kept in mind in the management of HCC patients.

A 50-year-old man was diagnosed with non-Hodgkin's lymphoma (NHL) in 1980; he was treated with chemotherapy and achieved complete remission. Six years later he reported upper abdominal pain. Ultrasound (US) showed a 3-cm mass in the right lobe of the liver. Needle aspiration showed hepatocellular carcinoma (HCC). The patient was treated with radical resection of the tumor. Three years later (June 1989), abdominal US showed two lesions in the right lobe of the liver. Needle aspiration and tissue core biopsy showed NHL in one lesion and HCC in the other. The lymphomatous lesion resolved after chemotherapy. The patient died 30 months later (January 1992) from a gastrointestinal hemorrhage; the NHL was in complete remission. This case of the simultaneous presence of HCC and hepatic lymphoma is, to our knowledge, the first diagnosed in vivo.

From June 1981 to June 1989 we diagnosed 174 cases of hepatocellular carcinoma (HCC) at our institution (Piacenza, Northern Italy). Average age was 65.6 years; male to female ratio 3.4. 149 patients were cirrhotic (85.6%); alcohol abuse was present in 88/169 (52.1%); in 53/145 patients all hepatitis B virus markers were negative. Alpha-fetoprotein showed a low diagnostic sensitivity (values above 500 ng only in 49/169 or 29.0%). We used ultrasound (US) examination with a very high identification rate in all cases; pathological diagnosis was achieved by US guided fine-needle aspiration biopsy in 135 patients; in 13, by laparoscopy-histology. Metastases were found in 24/169 cases (14.2%); a second malignancy was diagnosed in 13/169 (7.7%): the most common association was HCC-non-Hodgkin lymphoma. Only 14 patients could be referred to surgery, which significantly improved prognosis.

Four patients with hepatocellular carcinoma (HCC) out of a group of 132 with non-Hodgkin's lymphoma (NHL) are described. HCC was the most common second neoplasm in this series; in contrast, only 2 cases of HCC associated with NHL have been reported in the English literature. The diagnosis of HCC was suggested by ultrasound (US) and confirmed by ultrasonically guided fine-needle biopsy (UG-FNB). The 4 cases of HCC arose from cirrhosis. In this series, 10 out of 132 patients (7.6%) presented cirrhosis. Some considerations concerning the possible role of NHL (and/or the related therapy) in promoting the development of HCC in cirrhotic patients are discussed. The usefulness of US and of UG-FNB in the management of the patient with NHL is emphasized.

Angioimmunoblastic lymphadenopathy with disproteinemia (AILD) is a rare lymphoproliferative disorder. The clinical course varies and about 15-20% of the patients develop a malignant lymphoma. The association of AILD and carcinoma is very rare: only 4 cases have been reported in the literature. They are reviewed here and 1 case is described. This case is of special interest for the following reasons: (1) the exceptional length of time which elapsed between the diagnosis of AILD and the onset of an adenocarcinoma of the colon (118 months); (2) the long survival (the patient is still alive and well 140 months after the diagnosis of AILD); (3) unlike the cases reviewed, in our patient the carcinoma was diagnosed when AILD was in clinical remission, so a radical treatment was possible. In the cases previously reported, carcinomas arose in the lung (2 patients), pancreas (1 case), and stomach (1 case). The rare association of AILD and carcinoma is probably coincidental; however, the growth of solid tumors of nonlymphoid nature may be related to the impaired T cell function, and should be kept in mind in the management of patients with AILD.

We analyzed the clinical-diagnostic features of 67 cases of hepatocellular carcinoma (HCC) collected from June 1981 to December 1985. The male-to-female ratio was 3.4:1, the average age was 66.7 years; alcohol abuse was present in 38 cases (56.7%); HbsAg positivity was present in 10 of 62 patients (16.1%); the alpha-fetoprotein (AFP) level was greater than 500 ng in 17 of 61 patients (28%) and normal in 24 of 61 (39.3%). Concomitant cirrhosis was found in 51 patients (76.1%). The median survival of the whole group was of 10 weeks from diagnosis. The clinical suspicion of HCC was arisen by ultrasound (US) and the diagnostic was confirmed cytologically in 57 patients out of 60 who underwent ultrasonically guided fine-needle biopsy (UG-FNB), with a sensitivity of 95% and specificity of 100%. In 7 cases (including the 3 false-negative FNB), the diagnosis was made by laparoscopic biopsy and, in 3 cases, on autopsy. US identified a single tumor in 27 cases (40.3%); 7 were smaller than 5 cm. Only 4 patients (5.9%) were considered for surgery. We conclude that the cirrhotic patients (above all those HbsAg positive) constitute a high-risk group requiring periodic (every 3 months) US examination. To confirm the HCC, we believe in the high diagnostic accuracy of UG-FNB, whereas laparoscopy should be confirmed to the cases where FNB gives a doubtful false-negative result or to complete the presurgical staging.

In a series of 160 ultrasonically guided fine needle aspiration (FNA) biopsies, immediate cytologic evaluation of each specimen's adequacy was performed using a rapid staining method. The number of passes was thus limited to what was strictly necessary in order to obtain sufficient material; the average number of passes was only 1.27 per patient. The total series of FNA biopsies had a sensitivity of 95.6%, a specificity of 100% and an overall accuracy of 97.3%. In addition, the cumulative accuracy after each pass was calculated. A significant increase in diagnostic accuracy was found only after the second pass; the third and the fourth passes gave little further improvement. The results indicate that a rapid evaluation of the aspirated material during ultrasound-guided FNA biopsy can reduce the number of punctures needed per case, resulting in less discomfort and, probably, a reduced likelihood of complications for the patient. The results also suggest that a maximum of two punctures will probably yield adequate diagnostic material in most cases.
