Purpose:The objective of this expanded phase II trial was to confirm the safety results of the preceding phase I study and establish the efficacy of neoadjuvant radiochemotherapy with capecitabine in rectal cancer in a multicenter setting.Patients and Methods:96 patients (63% male, age 34–81 years) with advanced rectal cancer (cT3–4 or cN+) from seven university centers in Germany were recruited. All were to receive a total irradiation dose of 50.4–55.8 Gy with conventional fractions. Capecitabine was given at an oral dosage of 825 mg/m2bid on each day of the radiotherapy period with the first daily dose applied 2 h before irradiation, followed by surgery 6 weeks later.Results:Most of the patients suffered from an advanced primary tumor (cT3: 57%, cT4: 40%) with lymph node involvement in 60%. After neoadjuvant treatment, with a mean of 99% of the scheduled radiation dose actually delivered, a clinical response rate of 68% (95% confidence interval: 57–78%) was observed. Out of 87 evaluable patients undergoing surgery, a sphincter-preserving procedure could be performed in 51% and R0 resection in 94%. A pathologically complete response was achieved in six patients (7%, 95% confidence interval: 3–14%). The comparison of initial diagnosis and pathologic findings showed a downstaging in 61%. Acute toxicity with > 5% incidence of NCI (National Cancer Institute) grade ≥ 3 included lymphopenia (12%), leukopenia (6%), and diarrhea (7%). Mild to moderate hand-foot syndrome occurred in 12% only. After a median follow-up of 48 months, the 5-year overall survival and tumor control data were, with regard to patient selection, in the expected range with an overall survival of 65%, a relapse-free survival of 47%, and a local recurrence rate after 5 years of 17%.Conclusion:The data clearly confirm that capecitabine is an adequate substitute for 5-fluorouracil in preoperative chemoradiation of rectal cancer with a favorable safety profile.Ziel:Diese multizentrische Phase-II-Studie sollte Effektivität und Toxizität einer neoadjuvanten Radiochemotherapie mit Capecitabine prüfen.Patienten und Methodik:96 Patienten (davon 63% männlich, Alter 34–81 Jahre) mit lokal fortgeschrittenem Rektumkarzinom (cT3–4 oder cN+) aus sieben deutschen Universitätskliniken wurden rekrutiert. Alle erhielten eine präoperative Radiotherapie (50,4–55,8 Gy in konventioneller Fraktionierung mit 5 × 1,8 Gy) und zusätzlich 2 × täglich 825 mg/m2Capecitabin während gesamten Radiotherapie (erste Dosis 2 h vor Radiotherapie, keine Pause am Wochenende). 6 Wochen nach der Radiochemotherapie war die Resektion geplant.Ergebnisse:97% der Patienten hatten T3/T4-Tumoren (T3: 57%; T4: 40%). Lymphknotenbefall (cN+) lag in 60% vor. Die präoperative Therapie war gut durchführbar (mittlere Strahlendosis 99%, mittlere Capecitabindosis 96% der geplanten Dosis). Die klinische Ansprechrate betrug 68% (95%-Konfidenzintervall: 57–78%) und entsprach der Studienhypothese. Von 87 auswertbaren operierten Patienten wurden 94% R0-reseziert; ein Sphinktererhalt war in 51% möglich. Sechs Patienten (7%, 95%-Konfidenzintervall: 3–14%) hatten eine histologisch komplette Remission (ypT0) im Resektat. Ein Downstaging wurde in 61% erreicht. Akute Nebenwirkungen CTC-Grad ≥ 3 (Common Toxicity Criteria) mit einer Frequenz von > 5% wurden für Lymphopenie (12%), Diarrhö (7%) und Leukopenie (6%) beobachtet. Ein Hand-Fuß-Syndrom trat in 12% auf und war jeweils nur mild (Grad 1–2). Die 5-Jahres-Überlebensrate betrug 65%, das rezidivfreie Überleben 47% und die lokale Kontrolle nach 5 Jahren 83%.Schlussfolgerung:Die Daten dieser multizentrischen Phase-II-Studie bestätigen, dass die Kombination von präoperativer Radiotherapie und Capecitabin eine wirksame und nebenwirkungsarme Behandlung beim lokal fortgeschrittenen Rektumkarzinom darstellt. Capecitabin eignet sich als Ersatz für eine kontinuierliche 5-Fluorouracil-Infusion.

Background and Purpose: To assess treatment outcome and prognostic factors following postoperative external radiotherapy in 77 patients with low-grade glioma. Patients and Methods: Between 1977 and 1996, 45 patients with astrocytoma, 14 with oligodendroglioma and 18 with mixed glioma received postoperative radiotherapy with a median total dose of 52 Gy (range, 45 to 61 Gy). Sixty-seven patients were treated immediately following surgery, 10 patients with tumor progression. The influence of various factors including histology, gender, age, seizures, duration of symptoms (≤ 6 weeks vs > 6 weeks), CT pattern (enhancement vs no enhancement), type of surgery, total radiotherapy dose and timing of radiotherapy on relapse-free survival and overall survival was investigated. Results: The median overall survival time was 81 month, the 5- and 10-year survival rates were 54% and 31%, respectively. The median time to progression was 56 months, while the 5- and 10-year progression-free survival rates were 45% and 24%. Univariate analyses identified the total radiotherapy dose (p = 0.01), duration of symptoms (p = 0.05), the presence of seizures (p = 0.04), and the CT pattern following intravenous contrast (p = 0.005) as significant prognostic factors for overall survival. Progression-free survival rates were influenced by the total dose (p = 0.04), the duration of symptoms (p = 0.01) and CT pattern (p = 0.006). On multivariate analysis, only the CT pattern (enhancement vs no enhancement) remained as independent prognostic factors for both progression-free survival and overall survival. Conclusion: A minimum total dose of 52 Gy is recommended for the postoperative radiotherapy in low-grade glioma. Tumors with CT enhancement seem to need further intensification of treatment.Hintergrund: Es sollten Ergebnisse und Prognosefaktoren nach postoperativer Radiotherapie bei 77 Patienten mit Low-grade-Gliomen evaluiert werden. Patienten und Methoden: Zwischen 1977 und 1996 wurden 45 Patienten mit einem Low-grade-Astrozytom, 14 mit einem Oligodendrogliom und 18 mit einem gemischten Gliom postoperativ bis zu einer medianen Gesamtdosis von 52 Gy bestrahlt (Spanne zwischen 45 und 61 Gy). 67 Patienten wurden unmittelbar postoperativ, zehn Patienten erst nach computertomographischer Progression bestrahlt. Der Einfluss verschiedener Faktoren einschließlich Histologie, Geschlecht, Alter, Anfallsleiden, Dauer der Symptome vor Therapiebeginn (≤ 6 Wochen gegenüber > 6 Wochen), CT-Befunde (Kontrastmittelaufnahme vs. keine Aufnahme), Art der Operation, Gesamtdosis der Radiotherapie und Zeitpunkt der Radiotherapie für die Endpunkte progressions- oder rezidivfreies Überleben und Gesamtüberleben wurde untersucht. Ergebnisse: Das mediane Gesamtüberleben betrug 81 Monate, die Fünf- und Zehn-Jahres-Überlebensraten waren 54 und 31%. Die mediane Zeit bis zur Progression betrug 56 Monate, während die progressionsfreien Fünf- und Zehn-Jahres-Überlebensraten bei 45 und 27% lagen. In univariaten Analysen wurden die Gesamtdosis der Radiotherapie (p = 0,01), die Dauer der Symptome (p = 0,05), das Vorhandensein von Anfällen (p = 0,04) und die Kontrastmittelaufnahme im prätherapeutischen CT (p = 0,005) als signifikante Prognosefaktoren für das Gesamtüberleben identifiziert. Die progressionsfreie Überlebensrate wurde durch die Gesamtdosis der Radiotherapie (p = 0,04), die Dauer der Symtpomatik (p = 0,01) und die Kontrastmittelaufnahme im CT (p = 0,006) beeinflusst. In der multivariaten Analyse blieb lediglich das Kontrastmittelverhalten im CT (Aufnahme vs. keine Aufnahme) als unabhängige Prognosefaktoren für das Gesamtüberleben und das rezidivfreie Überleben übrig. Schlussfolgerung: Eine minimale Gesamtdosis von 52 Gy ist im Rahmen der postoperativen Radiotherapie von Low-grade-Gliomen empfohlen. Tumoren mit einer Kontrastmittelaufnahme im CT scheinen eine weitere Intensivierung der Therapie zu benötigen.

Combined modality therapy for rectal cancer

Bruce D. Minsky; Claus Roedel; Vincenzo Valentini

The standard adjuvant treatment for cT3 and/or N+ rectal cancer is preoperative chemoradiation. However, there are many controversies regarding this approach. These include the role of short course radiation, whether postoperative adjuvant chemotherapy necessary for all patients and whether the type of surgery after chemoradiation should be based on the response rate. More accurate imaging techniques and/or molecular markers may help identify patients with positive pelvic nodes to reduce the chance of overtreatment with preoperative therapy. Will more effective systemic agents both improve the results of radiation as well as modify the need for pelvic radiation? These questions and others remain active areas of clinical investigation.

BACKGROUND Care for patients with colon and rectal cancer has improved in the last 20years; however considerable variation still exists in cancer management and outcome between European countries. Large variation is also apparent between national guidelines and patterns of cancer care in Europe. Therefore, EURECCA, which is the acronym of European Registration of Cancer Care, is aiming at defining core treatment strategies and developing a European audit structure in order to improve the quality of care for all patients with colon and rectal cancer. In December 2012, the first multidisciplinary consensus conference about cancer of the colon and rectum was held. The expert panel consisted of representatives of European scientific organisations involved in cancer care of patients with colon and rectal cancer and representatives of national colorectal registries. METHODS The expert panel had delegates of the European Society of Surgical Oncology (ESSO), European Society for Radiotherapy & Oncology (ESTRO), European Society of Pathology (ESP), European Society for Medical Oncology (ESMO), European Society of Radiology (ESR), European Society of Coloproctology (ESCP), European CanCer Organisation (ECCO), European Oncology Nursing Society (EONS) and the European Colorectal Cancer Patient Organisation (EuropaColon), as well as delegates from national registries or audits. Consensus was achieved using the Delphi method. For the Delphi process, multidisciplinary experts were invited to comment and vote three web-based online voting rounds and to lecture on the subjects during the meeting (13th-15th December 2012). The sentences in the consensus document were available during the meeting and a televoting round during the conference by all participants was performed. This manuscript covers all sentences of the consensus document with the result of the voting. The consensus document represents sections on diagnostics, pathology, surgery, medical oncology, radiotherapy, and follow-up where applicable for treatment of colon cancer, rectal cancer and metastatic colorectal disease separately. Moreover, evidence based algorithms for diagnostics and treatment were composed which were also submitted to the Delphi process. RESULTS The total number of the voted sentences was 465. All chapters were voted on by at least 75% of the experts. Of the 465 sentences, 84% achieved large consensus, 6% achieved moderate consensus, and 7% resulted in minimum consensus. Only 3% was disagreed by more than 50% of the members. CONCLUSIONS Multidisciplinary consensus on key diagnostic and treatment issues for colon and rectal cancer management using the Delphi method was successful. This consensus document embodies the expertise of professionals from all disciplines involved in the care for patients with colon and rectal cancer. Diagnostic and treatment algorithms were developed to implement the current evidence and to define core treatment guidance for multidisciplinary team management of colon and rectal cancer throughout Europe.
