BackgroundTo prospectively evaluate the efficacy and safety of selective internal radiation (SIR) spheres in patients with inoperable liver metastases from colorectal cancer who have failed 5FU based chemotherapy.MethodsPatients were prospectively enrolled at three Australian centres. All patients had previously received 5-FU based chemotherapy for metastatic colorectal cancer. Patients were ECOG 0–2 and had liver dominant or liver only disease. Concurrent 5-FU was given at investigator discretion.ResultsThirty patients were treated between January 2002 and March 2004. As of July 2004 the median follow-up is 18.3 months. Median patient age was 61.7 years (range 36 – 77). Twenty-nine patients are evaluable for toxicity and response. There were 10 partial responses (33%), with the median duration of response being 8.3 months (range 2–18) and median time to progression of 5.3 mths. Response rates were lower (21%) and progression free survival shorter (3.9 mths) in patients that had received all standard chemotherapy options (n = 14). No responses were seen in patients with a poor performance status (n = 3) or extrahepatic disease (n = 6). Overall treatment related toxicity was acceptable, however significant late toxicity included 4 cases of gastric ulceration.ConclusionIn patients with metastatic colorectal cancer that have previously received treatment with 5-FU based chemotherapy, treatment with SIR-spheres has demonstrated encouraging activity. Further studies are required to better define the subsets of patients most likely to respond.

The changing treatment landscape for metastatic colorectal cancer creates multiple potential treatment strategies. An Australian‐centric database capturing comprehensive information across a range of treatment locations would create a valuable resource enabling multiple important research questions to be addressed.

Re: Residual Treatment Disparities After Oncology Referral for Rectal Cancer

The recent article by Morris et al. (1) is of interest. Their analysis of Surveillance, Epidemiology, and End Results (SEER) data produced an unexpected finding that disparities between black and white patients in the use of adjuvant treatment for rectal cancer were seen particularly in younger and fitter patients. Although a strength of this study was the inclusion of data regarding consultation rates, the limitations of the data analyzed create uncertainty about the conclusions that were reached. One concern is that the authors excluded 1931 (41.5%) of the original 4647 patients examined, with clear imbalances in the proportions of black and white patients who were excluded. Ultimately, the authors included data for only 134 black patients, of whom a disproportionately high number were female, which limited the power of the study and possibly introduced substantial bias. The imbalances in exclusions may be one reason that the results are inconsistent with those of other independent series, including a prior SEER analysis which found that racial differences in adjuvant chemotherapy use for colon cancer were less common in younger patients (2). The use of data from 1992 to 1999 instead of more recent data may also limit the relevance of the fi ndings. Since the 1990s, there has been a fundamental change in practice such that preoperative chemora-diation is now standard practice. Of interest , a US study of more than 85 000 patients treated between 1990 and 2002 concluded that in 2001 and 2002, compared with prior years, there were no longer statistically signifi cant racial differences in the receipt of adjuvant chemotherapy for stage III colon cancer (3). To explore the impact of age, tumor site, and the timing of therapy on patient acceptance of treatment, we examined our comprehensive colorectal cancer data (4), which were prospectively collected at four hospitals between January 2003 and February 2008. From a total sample of 530 patients offered adjuvant treatment, 40 (12.8%) of 313 patients with primary colon cancer declined the recommended chemotherapy (Table 1). With advancing patient age, physicians were less likely to offer treatment and patients were more likely to refuse treatment. For rectal cancer , only nine (4.1%) of 217 patients declined adjuvant treatment, including only two (1.5%) of 133 patients who were offered treatment in the preoperative setting. Our data indicate that it is not uncommon for patients to decline adjuvant therapy , which can have a substantial impact …

Debate continues regarding the benefits versus risks of initial resection of the primary tumor in metastatic colorectal cancer (mCRC) patients with an asymptomatic primary tumor. Although the benefit of the anti‐vascular endothelial growth factor agent bevacizumab alongside first‐line chemotherapy in mCRC is established, the impact of bevacizumab on the intact primary tumor (IPT) is less well understood.

742 Background: The liver is the dominant site of metastasis in patients (pts) with mCRC. Radioembolisation is a potential option in the multidisciplinary management of these patients. Recently initial analysis of a randomised controlled trial (RCT) in the 1st line setting demonstrated no overall progression free survival (PFS) benefit from adding SIRT, but prolongation of liver PFS (HR 0.69, p=0.002) was seen. Methods: Consecutive pts with mCRC enrolled from January 2009 were identified from a prospective multi-site Australian registry. Characteristics and outcomes for pts selected for treatment with SIRT were analysed. Results: Of 1,694 pts with mCRC, 580 (34.2%) had liver only disease at diagnosis, 409/580 (70.5%) with synchronous vs 166/580 (28.6%) with metachronous disease. Of pts with liver only disease, 187 (32.2%) were considered resectable at diagnosis, 100 (17%) as potentially resectable and 293 (51%) were treated with palliative intent. Overall 47 pts received SIRT with 1stline chemotherapy (CT...

ZusammenfassungFragestellung und Hintergrund:Die Standardbehandlung eines Rektumkarzinoms wird immer noch von den Ergebnissen randomisierter, klinischer Studien definiert, die den optimalen Zeitpunkt und den Einsatz von adjuvanter Chemotherapie und Bestrahlung im Vergleich mit einer Operation untersuchen. Die klinischen Problemstellungen, für die nur begrenztes aktuelles Datenmaterial als Hilfestellung bei der Entscheidungsfindung zur Verfügung steht, finden sich bei Patienten mit Rektumkarzinom im höheren Alter und/oder signifikanten Begleiterkrankungen sowie bei Patienten, die eine Operation ablehnen.Methodik:An sechs australischen Kliniken wurde eine retrospektive Analyse von Rektumkarzinompatienten, die aufgrund eines sehr hohen operativen Risikos oder Verweigerung einer Operation ausschließlich mit Bestrahlung oder einer Radiochemotherapie behandelt worden waren, durchgeführt.Ergebnisse:Identifiziert wurden 48 Patienten mit einem medianen Alter von 76 Jahren (49–94 Jahre), die zwischen August 1998 und Juni 2005 behandelt worden waren. 24 Patienten (50%) wurden als medizinisch inoperabel eingestuft, und 24 Patienten lehnten eine Operation ab. Die Behandlung bestand bei 36 Patienten aus einer Radiochemotherapie (mit 5-Fluorouracil) und bei zwölf Patienten aus ausschließlicher Bestrahlung; 93% führten die geplante Behandlung bis zum Ende durch. Bei 56% wurde ein komplettes klinisches Ansprechen und bei 30% ein partielles Ansprechen festgestellt. Bei einem medianen Follow-up von 49 Monaten zeigte sich bei 18 Patienten ein Fortschreiten der Erkrankung; dies betraf zehn von 24 Patienten in der medizinisch inoperablen Gruppe sowie acht von 24 Patienten in der Gruppe, die eine Operation verweigerte. Von den 25 verstorbenen Patienten waren 16 an der fortschreitenden Erkrankung und neun an nicht karzinombezogenen Ursachen gestorben.Schlussfolgerungen:Radiochemotherapie oder ausschließliche Bestrahlung stellt eine sichere Alternative dar, die bei medizinisch als inoperabel eingestuften oder eine Operation verweigernden Patienten in einem signifikant längeren progressionsfreien Überleben und Gesamtüberleben resultiert. Letztendlich wird die Erkrankung allerdings bei vielen Patienten fortschreiten.AbstractPurpose:The standard management of rectal cancer continues to be defined by the results of randomized, clinical trials exploring the optimal timing and use of adjuvant chemotherapy and radiation therapy in relation to surgery. The patient with rectal cancer who is elderly and/or has significant comorbidities and the patient who refuses surgery are clinical contexts for which there is limited current data to guide decision making.Methods:A retrospective analysis was performed at six Australian centers of patients with rectal cancer treated with radiation therapy or chemoradiation alone because of excessive operative risk or patient refusal of surgery.Results:We identified 48 patients treated between August 1998 and June 2005 with a median age of 76 (range, 49–94) years. Twenty-four patients (50 percent) were considered medically inoperable and 24 patients refused surgery. Treatment was with chemoradiation (with 5-fluorouracil) in 36 patients and radiotherapy alone in twelve patients; 93 percent completed the planned therapy. A clinical complete response was seen in 56 percent and a partial response in 30 percent of patients. At a median follow- up of 49 months, 18 patients have disease progression, including ten of 24 in the medically inoperable group and eight of 24 in the refused surgery group. Of the 25 deceased patients, 16 died from progressive disease and nine from noncancer causes.Conclusions:Chemoradiation or radiotherapy alone is a safe alternative that results in significant progression-free and overall survival times in patients who are considered medically inoperable or refuse to undergo surgery. Ultimately, however, many patients will progress.
