The role of lung metastasis resection in improving outcome of colorectal cancer patients: results from a large retrospective study.

BACKGROUND: The role of surgery for lung metastases (LM) secondary to colorectal cancer (CRC) remains controversial. The bulk of evidence is derived from single surgical series, hampering any definitive conclusions. The aim of this study was to compare the outcomes of CRC patients with LM submitted to surgery with those who were not. PATIENTS AND METHODS: Data from 409 patients with LM as the first evidence of advanced disease were extracted from a database of 1,411 patients. Patients were divided into three groups: G1, comprised of 155 patients with pulmonary and extrapulmonary metastases; G2, comprised of 104 patients with LM only and no surgery; G3, comprised of 50 patients with LM only and submitted to surgery. RESULTS: No difference in response rates emerged between G1 and G2. Median progression-free survival (PFS) times were: 10.3 months, 10.5 months, and 26.2 months for G1, G2, and G3, respectively. No difference in PFS times was observed between G1 and G2, whereas there was a statistically significant difference between G2 and G3. Median overall survival times were 24.2 months, 31.5 months, and 72.4 months, respectively. Survival times were longer in resected patients: 17 survived >5 years and three survived >10 years. In patients with LM only and no surgery, four survived for 5 years and none survived >10 years. CONCLUSIONS: Even though patients with resectable LM are more likely to be those with a better outcome, our study provides evidence suggesting an active role of surgery in improving survival outcomes in this patient subset.

Adjuvant treatment for elderly patients with colon cancer. An observational study.

BACKGROUND: Adjuvant 5-fluoruracil-based chemotherapy significantly reduces mortality in patients with stage II-III colon cancer, but is less prescribed with rising age. In this study we were interested in the pattern of adjuvant treatment and possible effects on survival among elderly patients. PATIENTS AND METHODS: From January to December 2004, 63 questionnaires on the management of stage II-III resected colon cancer patients aged over 70 years, collected from 10 Italian Centres, were retrospectively examined. Determinants of receipt of adjuvant chemotherapy and their relation to survival were considered. RESULTS: The proportion of elderly patients receiving adjuvant chemotherapy was 79.4%, distinct of age, gender, educational level and comorbidities. Grade 3-4 toxicities were the following: haematological in 4 (8.5.%) patients, mucositis in 4 (8.5%), diarrhoea in 2 (4.2%) and nausea in 1 (2.1%). The disease-free survival (DFS) and overall survival (OS) at two years were 79.9% and 95.6%, respectively. Due to the paucity of events, the impact of prognostic factors (patient's age and comorbidity, tumour stage and grade) on DFS and OS could not be assessed. CONCLUSION: An increasing proportion of elderly patients with colon cancer may be treated with a tolerability and OS similar to those observed in the younger population. Development of age-based guidelines and increased awareness of both physicians and patients through education is important to prevent undertreatment of those elderly patients who are eligible for chemotherapy.

Colorectal cancer treatment in elderly patients: results of a retrospective analysis addressed to the chiefs of medical oncology units in Italy.

BACKGROUND: The aim of this retrospective analysis was to evaluate the differences of 1-year treatment and chemotherapy related-toxicity in elderly colorectal cancer (CRC) patients in different Italian medical oncology units. PATIENTS AND METHODS: An open questionnaire on the management of CRC patients over 70 years of age, from January to December 2004, was sent to Italian centres. One hundred and seventy-five files from 10 centres were analysed. Variables considered were age, gender, educational level, comorbidities and modality of therapy administration. RESULTS: In only a minority of units were there some staff specifically dedicated to the older patients in close cooperation with geriatricians and the Multidimensional Geriatric Assessment (MGA) was not routinely used (11.2%-16.8% of cases). Only 5.7% patients were routinely enrolled in a protocol. In total, 95 out of 175 (54.3%) of CRC underwent adjuvant chemotherapy and 80 out of 175 (45.7%) received palliative chemotherapy. Of the patients who underwent adjuvant chemotherapy, 75.6% immediately accepted postoperative treatment while 12.2% were initially dubious but subsequently agreed. Only 5.5 and 9.7% of these patients reported very bad or bad tolerability, respectively. At disease progression, 62.5% patients accepted chemotherapy instantly while 33.3% accepted subsequently. Only 1.3% cases reported very bad and 1.3% bad tolerability. CONCLUSION: In those units in which the problem of the elderly is actually recognised, CRC treatment is adequate, not influenced by age discrimination but inhomogeneous. In the future, standardizing treatment in different oncology units could prove to be beneficial to this population.
