    ABSTRACT: To evaluate and compare the efficacy of medium-dose-rate (MDR) and low-dose-rate (LDR) intracavitary brachytherapy (ICBT) for uterine cervical cancer. We evaluated 419 patients with squamous cell carcinoma of the cervix who were treated by radical radiotherapy with curative intent at Tokyo Women's Medical University from 1969 to 1999. LDR was used from 1969 to 1986, and MDR has been used since July 1987. When compared with LDR, fraction dose was decreased and fraction size was increased (1 or 2 fractions) for MDR to make the total dose of MDR equal to that of LDR. In general, the patients received a total dose of 60 to 70 Gy at Point A with external beam radiotherapy combined with brachytherapy according to the International Federation of Gynecology and Obstetrics stage. In the LDR group, 32 patients had Stage I disease, 81 had Stage II, 182 had Stage III, and 29 had Stage IVA; in the MDR group, 9 patients had Stage I disease, 19 had Stage II, 55 had Stage III, and 12 had Stage IVA. The 5-year overall survival rates for Stages I, II, III, and IVA in the LDR group were 78%, 72%, 55%, and 34%, respectively. In the MDR group, the 5-year overall survival rates were 100%, 68%, 52%, and 42%, respectively. No significant statistical differences were seen between the two groups. The actuarial rates of late complications Grade 2 or greater at 5 years for the rectum, bladder, and small intestine in the LDR group were 11.1%, 5.8%, and 2.0%, respectively. The rates for the MDR group were 11.7%, 4.2%, and 2.6%, respectively, all of which were without statistical differences. These data suggest that MDR ICBT is effective, useful, and equally as good as LDR ICBT in daytime (about 5 hours) treatments of patients with cervical cancer.

    ABSTRACT: The aim of this study was to evaluate the impact of dysadherin and E-cadherin expression on the clinical outcomes, including the treatment outcomes and recurrence pattern, in patients with head and neck cancer. Tumor specimens were obtained from 48 head and neck cancer patients who were treated by radiation therapy and the specimens were immunohistochemically stained for dysadherin and E-cadherin. The expressions were graded according to the percentage area occupied by cancer cells showing positive staining for E-cadherin and dysadherin as follows: grade 0, less than 10%; grade 1, 10-50%; grade 2, more than 50%. The correlations between the expression of E-cadherin and dysadherin and the clinical outcomes, including the treatment outcomes and recurrence pattern, were analyzed. The complete response (CR) rate in the patients with a dysadherin expression grade of 0 or 1 was 70% and that in the patients with dysadherin expression grade of 2 was 38%; the difference was significant (p < 0.05). Regarding the pattern of recurrence, the expression grade of dysadherin or E-cadherin alone was not correlated with the recurrence pattern; however, patients with a difference in the expression grade between dysadherin and E-cadherin (Dys-Ecad value) of 1 or 2 showed a significantly higher rate of lymph node and/or distant metastasis (55%) as compared with those with a Dys-Ecad value of < 1 (22%) (p < 0.05). Dysadherin and E-cadherin expression might serve as useful prognostic factors in patients with head and neck cancer treated by definitive radiation therapy.
