Hyperfractionation in advanced carcinoma of the uterine cervix: a preliminary report.

Experience with twice-a-day radiation therapy program for carcinoma of the uterine cervix (FIGO Stages IIB, IIIA & IIIB) is presented. The program consists of delivering 120 cGy per fraction, two fractions a day with 6 hours between fractions. A total of 6000 cGy was delivered in 50 fractions over 5 weeks. A control group was given conventional fractionation 5000 cGy in 25 fractions, 200 cGy per fraction over 5 weeks. This feasibility study enrolled 30 patients, 15 in each group. Normal tissue reactions in skin, mucosa and bowel were recorded. The acute normal tissue reactions were enhanced in the hyperfractionation group. This was significant with regard to the bowel complications. The tumor control rate did not show any significant difference between the two groups. A short follow-up period has revealed complete healing of all acute normal tissue reactions. This study shows that further dose escalation is feasible and a study with large sample size and longer follow-up is required to reach definite conclusions.

Combined hepatocellular and cystadenocarcinoma presenting as a giant cyst of the liver--a case report.

Primary cystic lesions of the liver are very rare. Most of the solid tumours are hepatocellular carcinomas (HCC) with a smaller number being cholangiocarcinomas. The association of HCC with other primary liver malignancies is also extremely rare. This case report is about a 27 year old male patient who presented with a giant cystic lesion of the left liver. A CT scan showed a cystic lesion with internal septations and a thrombus in the main portal vein. The patient underwent an extended left hepatectomy and a portal venotomy with removal of the thrombus. Coexistent hepatocellular and cystadenocarcinoma were reported on histopathological examination. The patient was put on 5-FU postoperatively. He is doing well 11 months after surgery.

Asymptomatic T-tube remnant in common bile duct.

A 46-year-old lady presented with itching, five years after a primary common bile duct repair following cholecystectomy. Prior to this she underwent an interno-external biliary drainage. At laparotomy the horizontal limb of a T-tube was found in the common hepatic duct. Eleven months after a Roux loop hepatico-jejunostomy she is asymptomatic.
