Case ReportsAggressive undifferentiated carcinoma of unknown primary site complicated by lactic acidosis after bleeding: a case report.
Undifferentiated carcinoma of unknown primary site complicated by lactic acidosis has not been documented. We describe a young female with undifferentiated carcinoma of unknown primary site manifested by widespread lymph node and hepatic infiltration, hyperuricemia and very high levels of lactate dehydrogenase. ⋯ The bleeding episode is likely to have caused subclinical hepatic hypoperfusion and hypoxemia, thereby aggravating lactate overproduction by tumor cells and clearance impairment due to diffuse hepatic infiltration to result in rapidly fatal acidosis before cytotoxic agents could be instituted. Although uncommon, when a critical event occurs in aggressive malignancies with massive hepatic involvement, the clinician should be alert for the development of lactic acidosis because the life-threatening metabolic complication is best avoided by prompt and effective cytoreduction therapy.

High versus low dose rate intracavitary irradiation for adenocarcinoma of the uterine cervix.
Traditionally, low dose rate (LDR) brachytherapy has been used as a standard modality in the treatment of patients with carcinoma of the uterine cervix. The purpose of this work was to evaluate the effects of high dose rate (HDR) brachytherapy on patients with adenocarcinoma of the uterine cervix and to compare them with the effects of LDR brachytherapy. ⋯ There was no difference in terms of 5-year survival rate in the patients with adenocarcinoma of the uterine cervix between those treated with HDR and those treated with LDR brachytherapy. Even though late complication rates were higher in the HDR group, most of them were classified as grade I. This retrospective study suggests that HDR brachytherapy may be able to replace LDR brachytherapy in the treatment of adenocarcinoma of the uterine cervix.

Case ReportsHepatocellular carcinoma with Pancoast's syndrome as an initial symptom: a case report.
Pancoast's syndrome refers to a condition consisting of Horner's syndrome and arm pain that is most commonly found in patients with a lung tumor of the superior sulcus invading the upper ribs or spine, lower brachial plexus and sympathetic chain. We report a 76-year-old female who had a thoracic inlet mass that presented as Pancoast's syndrome, showing profound pain, numbness and weakness of the left upper limb. Further evaluation revealed an increased level of serum alpha-fetoprotein (24278 ng/ml), cryptogenic liver cirrhosis and primary hepatocellular carcinoma with protruding T3 vertebra metastasis that resulted in Pancoast's syndrome. To our knowledge, it is a rare case and only one case has been reported previously.
