摘要:

The study of multiple primary neoplasms may provide more insight into the pathogenesis of specific cancers and, secondly, it addresses the issue of treatment-related induction of second tumors. 584 consecutive patients with testicular germ cell tumors treated during 1969-1992 in Berlin were retrospectively analyzed for the prevalence of multiple primary neoplasms. 23 patients (16 pure seminoma, 7 nonseminoma) developing nontesticular malignancies in addition to testis cancer were identified (3.9%, 95 confidence intervals ± 1.6%). The mean age at the time of the testis cancer was 42.8 years, and mean age at the time of nontesticular malignancy was 50.2 years. In 4 cases, the nontesticular malignancy preceded testis cancer, in 3 patients both neoplasms occurred simultaneously, and in 16, nontesticular malignancies developed subsequently to testis cancer. In 4 patients, triple malignancies were observed. Bladder carcinoma and bronchogenic cancer with each 3 cases were the most frequent second neoplasms seen in these patients. 9 consecutive cancers developed within radiation fields, the median latency period in these cases was 12 years. None of the subsequent cancers developed after chemotherapy. It is concluded that genetic predisposition and radiation effects are the most important factors contributing to the occurrence of multiple primary neoplasms in patients with testicular germ cell cancer. The high rate of multiple primary neoplasms in these patients lends further evidence to the theory of genetic anticipation of germ cell cancer

摘要:

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 a-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 patient

摘要:

We report a rare case of a patient with an intrasplenic malignant fibrous histiocytoma (MFH) and chronic myelogenous leukemia. The neoplasms were synchronous in their onset and evolution. The peculiarity of the primary site of the MFH, the genetic implications of multiple primary tumors in a single patient, and the controversy about the cell precursors of MFH are briefly outlined.

摘要:

A cell-to-cell interaction between tumors and host inflammatory cells is important for the subsequent cancer progression or regression. We examined the expression of interleukin-8 (IL-8) mRNAs by 9 human lung cancer cell lines and the influences of cytokines on IL-8 production and its gene expression. Substantial expressions of IL-8 gene were detected in 3 lung cancer cell lines (RERF-LC-OK, Lu-134-A-H, YO-88 cells). Moreover, 4 lung cancer cell lines (RERF-LC-MS, RERF-LC-OK, A549 and YO-88) were used to examine the effects of exogenous cytokines – interleukin-1β (IL-1β), tumor necrosis factor a (TNF-α) and granulocyte-macrophage colony-stimulating factor – on IL-8 production by the cells at protein and gene levels. TNF-α and IL-1β3 significantly augmented the levels of mRNA expression for IL-8 and its production. These observations indicate that tumor-derived IL-8 may be important in recruiting inflammatory neutrophils and promoting interaction between lung cancer and inflammato

摘要:

Biological response modifiers have been extensively investigated in the management of patients with cancer, but few data are available on tumors of the gastrointestinal tracts. To evaluate the feasibility and activity of the combination of interleukin 2 (IL-2) and β-interferon (β-IFN), 15 patients with colorectal cancer and 10 patients with hepatocellular carcinoma were treated with the following outpatient schedule: β-IFN 3 × 106 U i.m. 3 times weekly from day 1 to day 14; IL-2 4.5 × 106 U s.c. every 12 for 5 consecutive days a week from day 7 to day 21, the cycles being repeated every 28 days. All of the patients had been previously treated with chemotherapy; 7 unresectable locally advanced, and 18 had metastatic disease. All of the treatment courses were administered in an outpatient setting. No grade 4 side effects were recorded. The worst side effects were grade 3 fever (4 patients) and asthenia (2 patients) requiring treatment discontinuation in 4 cases. Twenty-four patients were evaluated for response (14 with colorectal cancer and 10 with hepatocellular carcinoma). One partial response, 4 stable disease, 9 progressive disease were recorded among the colorectal patients; 4 stable disease and 6 progressive disease among the hepatocellular carcinoma patients. The median duration of stable disease was 3 months for hepatocellular carcinoma and 4 months for colorectal cancer patients. Our results suggest that the schedule is feasible in an outpatient setting. Its limited hematological toxicity makes it suitable to be combined with cytotoxic d
