Twenty-seven consecutive cases with a prospective diagnosis of cancer of the gallbladder were analyzed to clarify the computed tomographic (CT) and ultrasonographic features, behavior, and prognosis of intraluminal papillary carcinoma (n = 7) of the organ. With CT and ultrasonography, these intraluminal carcinomas were further classified into 3 subtypes: single polyp, multiple polyp, and jam-packed gallbladder. Preoperative diagnosis, evaluation of local invasiveness, and detection of metastatic lesions were reliably done. Carcinomas of this type were locally less invasive, less frequently metastasized, and resulted in a longer survival than the other massive and thickened-wall carcinomas.
HighlightsSpontaneous cancer remission without treatment is a known phenomenon with various types of cancer.Although spontaneous breast cancer remission has been thought to be a rare, this may occurs at a certain rate(not rare phenomenon).When cancer was not detected in the pathological specimen and there were no known biological markers to provide information for the decision regarding adjuvant therapy, observation without further treatment can be option.
Out of 79 consecutive cases of hepatocellular carcinoma (HCC) examined with computed tomography (CT), five patients revealed metastatic swollen abdominal lymph nodes. Involved were portal, retropancreatic, common hepatic, superior mesenteric, and paraaortic nodes. CT appeared to be an excellent modality in the diagnosis of metastatic abdominal lymph nodes of HCC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
