RESUMO
Patients with estrogen receptor (ER)+/progesterone receptor (PR)- and/or HER-2 overexpressing breast carcinomas may derive lower benefit from endocrine treatment. We examined retrospectively data from 972 breast cancer patients who received tamoxifen (725), tamoxifen + Gn-RH analogs (127) and aromatase inhibitors (120) as adjuvant treatments. ER+/PR- versus ER+/PR+ tumours were characterised by larger size (P = 0.001), higher tumour grade (P = 0.001), higher Ki-67 expression (P = 0.001) and lower mean ER (P = 0.000) and HER-2 expression (P = 0.000). At univariate analysis, tumour grading [hazard ratio (HR) = 4.0; 95% confidence interval (CI) = 1.4-11.1; P = 0.007], nodal status (HR = 3.4; 95% CI 1.2-5.7; P = 0.000), tumour diameter (HR = 2.9; 95% CI 1.7-4.7; P = 0.000) lack of PR expression (HR = 2.1; 95% CI 1.3-3.4; P = 0.002) and HER-2 overexpression (HR = 1.9; 95% CI 1.0-3.5; P = 0.03), as well as Ki 67 expression (HR = 1.7; 95% CI 1.0-2.7; P = 0.04) were associated with shorter disease-free survival (DFS). At the multivariate analysis, nodal status (HR = 3.6; 95% CI 1.9-6.8; P = 0.0001), lack of PR expression (HR = 2.3; 95% CI 1.3-4.0; P = 0.003) and tumour diameter (HR = 2.1; 95% CI 1.1-3.8; P = 0.018) retained their prognostic significance, whereas HER-2 overexpression was associated with a trend towards shorter DFS that was of borderline statistical significance (HR = 2.0; 95 % CI 1.0-3.9; P = 0.05). Our data suggest that lack of PR expression and HER-2 overexpression are both associated with aggressive tumour features, but the prognostic information of PR status on the risk of recurrence in endocrine-treated breast cancer patients is stronger.

We evaluated whether concurrent radiotherapy (RT) affected delivery and toxicity of adjuvant intravenous CMF (cyclophosphamide, methotrexate and 5-fluorouracil) in women with operable breast cancer. The medical charts of 321 consecutive breast cancer patients who received CMF either alone for 6 cycles, or for 4 cycles following of an anthracycline (A-CMF) were reviewed. One hundred forty-four women underwent radiotherapy concurrently with CMF. Optimal CMF delivery (success as opposite to failure) was defined as the combined achievement of an average relative dose intensity (aRDI) > or = 85% and an average percent of the total dose (aPTD) > or = 90% for the three drugs in the CMF regimen. Multivariate logistic regression analysis showed that concurrent-RT did not affect CMF delivery (OR for success 1.391 p=0.230). The sequential A-CMF regimen (OR for success 0.208, 95% C.I. 0.120-0.360, p<0.001) and age > or = 56 (OR for success 0.351, 95% C.I. 0.200-0.161, p<0.001) were independently associated with suboptimal CMF delivery. Moreover, concurrent RT was independently associated with increased leukopenia, thrombocytopenia, upper abdominal pain, mucositis and fatigue. Our retrospective analysis suggests that concurrent-RT has no impact on optimal CMF delivery, but it increases the burden of CMF-related toxicity.

UNLABELLED: The optimal treatment for cervical cancer is still a controversial matter: in the last two decades a lot of different modalities combining surgery, radiotherapy (RT) and chemotherapy (CHT) have been suggested and analysed in clinical trials. Nevertheless, analysis of treatment in cancer patients should be directed not only to survival, but also to the cost of complications and quality of life. In June 1988, a French-Italian co-operative group set up a glossary in which the complications of the treatment of cervical cancer are described and ranked. Nowadays, this is the only international system based upon an accurate description of symptoms and signs of complications following multidisciplinary treatment. The glossary was based on our previous experience in treating patients by surgery alone, RT or their combinations. Recently multimodality treatment includes also CHT. The aim of the present study was to verify whether the glossary is still a useful clinical instrument in outcome evaluation of cervical cancer treatment. MATERIALS AND METHODS: The analysis has been done on a retrospective consecutive series of 579 patients affected by cervical cancer, treated in five Italian institutions. A minimum of 12 months follow up was required. All medical records of the patients enrolled, were examined by two independent reviewers in order to classify the complications according to the glossary. RESULTS: Out of 579 patients 319 (55.1%) were free of complications and 260 (44.9%) experienced at least one complication. We found 436 complications. The distribution by Grade was: G1 58.9%, G2 27.5%, G3 13.5%. We had no fatal complication (G4). The glossary included all observed complications, except for pulmonary fibrosis. CONCLUSION: The glossary is still a useful instrument in evaluating the outcome of cervical cancer treatment, whatever the therapy, and should be considered in quality of life assessment.

PURPOSE OF INVESTIGATION: Surgery and radiotherapy achieved equivalent results for FIGO stages Ib-IIa invasive cervical carcinoma. The integration of radiotherapy and surgery provided the same results for a selected series of patients without increasing the rate of complications. The aim of the study was to verify if, applying a radio-surgical protocol, the reduction of the surgery extension on the parametrium in one of two consecutive series might achieve the same results in terms of survival and recurrence rates with fewer complications. MATERIAL AND METHODS: We analysed actuarial survival (with >10-year follow-up), local control rates and morbidity of 390 patients who had different the kinds of surgery applied in the radio-surgical treatment protocol: Protocol A: brachytherapy plus type III radical hysterectomy vs Protocol B: brachytherapy plus type II radical hysterectomy. Patients were all included in an analysis of complications according to the French-Italian glossary. RESULTS: Analyses showed no differences in terms of survival, patterns of recurrences and onset time within the two protocols. Urinary complications were more frequent and severe in protocol A vs protocol B (G2: 26.5% vs. 6.1%; G3: 5.3% vs. 3.6%). CONCLUSION: Our study pointed out that the reduction of the surgery extension allowed the same overall survival and relapses with fewer complications particularly in terms of grade of severity.
