- In a controlled prospective randomized study the regimen doxorubicin (A) 40 mg/m2 + melphalan (M) 0.4 mg/kg was compared with A + M + cisplatin (C) 50 mg/m2 given every four weeks in advanced ovarian cancer, FIGO stage III or IV and with serous or anaplastic histology. From 1981 to 1983, 300 patients entered the study and 295 patients were evaluable for response, toxicity and long-term survival. All patients were followed for at least 10 years. The majority of patients had large residual tumours >2 cm. Patients treated with MAC had a higher response rate compared with patients treated with MA (76% vs. 50%, p < 0.01) and treatment with MAC resulted in significantly more pathological complete responders than MA. There was a significant difference in median duration of response (19 months vs. 13 months, p < 0.006) and in median survival time (26 months vs. 19 months, p = 0.05). After 5- and 10 years a significant difference in progression-free and overall survival was found. The independent prognostic factors in this study were residual tumour after primary surgery, treatment with MAC, tumour grade, ascites, and stage. Objective and subjective side effects were significantly worse with MAC, although tolerable. In conclusion, this study shows that incorporating C into MA improves the duration of progression-free survival and overall survival in women with incompletely resected Stage III or Stage IV ovarian epithelial cancer. A 5- and 10-year survival of 25% and 18%, respectively, is impressive.

- The primary aim of this study was to investigate if the expression of the DNA damage identifying protein DNA-PKcs known to be involved in DNA repair after treatment with ionising radiation can be used as a predictive marker for radiotherapy (RT) response in cervical cancer. Formalin-fixed primary tumour biopsies from 109 patients with cervical cancer, FIGO-stage IB-IIA, treated with preoperative brachytherapy followed by radical surgery were analysed by immunohistochemistry. In addition, correlation studies between early pathological tumour response to radiation and expression of Ku86, Ku70, Mdm-2, p53 and p21 in primary tumours were also performed. We found that tumour-transformed tissue shows positive immunostaining of DNA-PKcs, Ku86 and Ku70, while non-neoplastic squamous epithelium and tumour-free cervix glands show negative immunoreactivity. Expression of DNA-PKcs positively correlated with both Ku86 and Ku70, and a statistically significant correlation between the Ku subunits was also found. After RT, 85 patients demonstrated pathologic complete remission (pCR), whereas 24 patients had residual tumour in the surgical specimen (non-pCR). The main finding of our study is that there was no correlation between the outcome of RT and the expression of DNA-PK subunits. Positive p53 tumours were significantly more common among non-pCR cases than in patients with pCR (P=0.031). Expression of p21 and Mdm-2 did not correlate with the outcome of RT.
