ObjectiveTo analyze the effects of 5-fluorouracil (5-FU) chemotherapy combined with preoperative irradiation and the role of intraoperative electron beam irradiation (IOERT) on the outcome of patients with primary locally advanced rectal or rectosigmoid cancer.
MethodsFrom 1978 to 1996, 145 patients with locally advanced rectal cancer underwent moderate-to high-dose preoperative irradiation followed by surgical resection. Ninety-three patients received 5-FU as a bolus for 3 days during the first and last weeks of radiation therapy (84 patients) or as a continuous infusion throughout irradiation (9 patients). At surgery, IOERT was administered to the surgical bed of 73 patients with persistent tumor adherence or residual disease in the pelvis.
ResultsNo differences in sphincter preservation, pathologic downstaging, or resectability rates were observed by 5-FU use.However, there were statistically significant improvements in 5-year actuarial local control and disease-specific survival in patients receiving 5-FU during irradiation compared with patients undergoing irradiation without 5-FU. For the 73 patients selected to receive IOERT, local control and disease-specific survival correlated with resection extent. For the 45 patients undergoing complete resection and IOERT, the 5-year actuarial local control and disease-specific survival were 89% and 63%, respectively. These figures were 65% and 32%, respectively, for the 28 patients undergoing IOERT for residual disease. The overall 5-year actuarial complication rate was 11%.
ConclusionsTreatment strategies using 5-FU during irradiation and IOERT for patients with locally advanced rectal cancer are beneficial and well tolerated.Carcinoma of the rectum is a heterogeneous disease. At one end of the clinical spectrum, a few patients with superficially invasive cancers are well served by limited procedures such as transanal local excision. The majority of patients with rectal cancer, however, have mobile but more deeply invasive tumors that require low anterior or abdominoperineal resection. At the less favorable end of the clinical spectrum are patients with locally advanced tumors that Address reprint requests to
Background:
Subcondylar fractures represent 25 to 35 percent of all mandibular fractures, yet the treatment paradigm has remained controversial. Closed treatment relies on the plasticity of the condyle head during recovery, whereas open treatment is challenging and risks facial nerve injury. Perioperative, functional, and patient-reported outcomes were measured to compare methods of open versus closed treatment of subcondylar fractures.
Methods:
Selected displaced subcondylar fracture cases with open (open reduction and internal fixation of subcondylar fracture with maxillomandibular fixation) versus closed (maxillomandibular fixation) treatment were compared (n = 60). Demographics, perioperative data, complications, persistent symptoms, chin deviation, malocclusion, change in mouth opening, functional scores, and FACE-Q patient satisfaction were recorded.
Results:
Open versus closed groups had similar demographics and perioperative data, except the open group had longer operating room time (76.39 minutes versus 56.15 minutes). In long-term follow-up, open-treated patients had fewer symptoms (9 percent versus 67 percent), less chin deviation (0 percent versus 40 percent), a less restricted mouth opening (3mm versus 5mm), and better functional scores (1.92 versus 0.861). Transient facial nerve weakness was seen in 6 percent of open cases.
Conclusion:
For selected subcondylar fracture patients, open treatment with endoscopic assistance, nerve monitoring, and specialized plates provides superior long-term results compared to closed treatment when considering symptoms and functional parameters.
