Adjuvant Systemic Therapies in Patients with Colorectal Cancer: An Audit on Clinical Practice in Italy

Importance of adherence to guidelines in breast cancer clinical practice. The Italian experience (AIOM)

Aims and background

Project RIGHT (Research for the Identification of the most effective and hIGHly accepted clinical guidelines for cancer Treatment) is promoted by the Italian Association of Medical Oncology (AIOM) to evaluate the concordance between AIOM breast cancer guidelines and clinical practice in Italy. In RIGHT-1, feasibility and the appropriateness of indicators were assessed in patients with early breast cancer. RIGHT-2 evaluated the compliance with guidelines in a nationwide program.

Methods

Thirty-five Italian centers participated in the RIGHT-2 survey. Ten indicators were evaluated to verify an agreement between 2005 AIOM breast cancer guidelines and practice. Patients with clinical stage I-II invasive breast cancer, age ≤70 years, who had their first visit at the oncology center between October 2005 and November 2006 were included.

Results

In RIGHT-2, ≥90% adherence for the diagnosis indicator and three therapy indicators were observed. The lowest degree of compliance (0%) was observed for the follow-up indicator in asymptomatic patients.

Conclusions

In RIGHT-2, compliance to the 2005 AIOM breast cancer guidelines was 64%. When the follow-up indicator was eliminated, overall adherence to AIOM guidelines was 71%. The results highlight the need to continue improving the already good standards of breast cancer care.

Patterns of colorectal cancer care in Europe, Australia, and New Zealand

Colorectal cancer is the second most common cancer in women and the third most common in men worldwide. In this study, we used MEDLINE to conduct a systematic review of existing literature published in English between 2000 and 2010 on patterns of colorectal cancer care. Specifically, this review examined 66 studies conducted in Europe, Australia, and New Zealand to assess patterns of initial care, post-diagnostic surveillance, and end-of-life care for colorectal cancer. The majority of studies in this review reported rates of initial care, and limited research examined either post-diagnostic surveillance or end-of-life care for colorectal cancer. Older colorectal cancer patients and individuals with comorbidities generally received less surgery, chemotherapy, or radiotherapy. Patients with lower socioeconomic status were less likely to receive treatment, and variations in patterns of care were observed by patient demographic and clinical characteristics, geographical location, and hospital setting. However, there was wide variability in data collection and measures, health-care systems, patient populations, and population representativeness, making direct comparisons challenging. Future research and policy efforts should emphasize increased comparability of data systems, promote data standardization, and encourage collaboration between and within European cancer registries and administrative databases.

Preoperative investigations for metastatic staging of colon and rectal cancer across multiple centres--what is current practice?

OBJECTIVE

The optimal strategy for elective distant staging of colorectal carcinoma (CRC) has yet to be defined, with current guidelines based on small and limited series. One specific issue requiring review is the value of routine computerized tomographic (CT) chest examination. Also lacking is data on current routine clinical practice.

METHOD

A retrospective chart review of consecutive cases of elective surgery for CRC from five hospitals.

RESULTS

Two hundred and fifty-seven cases were reviewed, 128 colon and 129 rectal primaries. 164 (64%) of patients overall, ranging from 45% to 88% across the individual centres, had a preoperative serum CEA level performed. CT abdomen/pelvis was performed in 222 (86%) of cases, ranging from 69% to 98% per centre. CT chest was performed in 95 (37%) of cases, 47% of rectal vs 29% of colon cancers (P = 0.004). In 17 cases (18%) CT chest examinations revealed abnormalities suspicious for metastatic disease, leading to a change in management in six (35%) of these cases. Of the 17 cases with an abnormal CT chest, in only 5 of the 14 (36%) where carcinoembryonic antigen (CEA) levels were also recorded was this increased, and in only three (21%) was this markedly (> 10 microg/l) elevated.

CONCLUSIONS

Substantial variability exists in the preoperative evaluation of patients with CRC. Many patients do not have a CEA and/or abdominal imaging performed. Where performed, CT chest revealed suspicious findings in a significant number of patients, the vast majority of whom had a normal or near normal CEA. Future studies are required to define optimal preoperative staging.

Adjuvant systemic chemotherapy with 5-fluorouracil and leucovorin in colon cancer: a monoinstitutional institutional experience

The efficacy of adjuvant chemotherapy in colon cancer has been well established in clinical trials, yet data on its routinely clinical practice are few. Two hundred forty-one patients were treated with fluorouracil-based adjuvant therapy from 1996 to 2001 and 147 out of 241 patients consecutively treated was aged 65 years or more at the time of diagnosis. Kaplan-Meyer progression-free survival and overall survival of stage II and III patients were calculated, the same statistic analyses were done for elderly population. Three- and 5-year overall survivals were respectively 94.4% and 90.4%. The survival observed in our retrospective study reflects that reported in the chemotherapy arm of randomized clinical trials. As expected, stage II patients survival was better than that of stage III patients (p = 0.0019, log-rank test). The treatment was generally well tolerated and there was no therapy related death and no clinical immonotoxicological effects was observed also in elderly patients.
