PURPOSE To evaluate potential prognostic factors for local control and survival after radiotherapy of metastatic spinal cord compression (MSCC). PATIENTS AND METHODS The following potential prognostic factors were investigated retrospectively in 1,852 patients irradiated for MSCC: age, sex, performance status, primary tumor, interval between tumor diagnosis and MSCC (< or = 15 v > 15 months), number of involved vertebrae (one to two v > or = three), other bone metastases, visceral metastases, pretreatment ambulatory status, time of developing motor deficits before radiotherapy (faster, 1 to 14 v slower, > 14 days), and radiation schedule (short-course v long-course radiotherapy). RESULTS On univariate analysis, improved local control of MSCC was associated significantly with favorable histology (breast cancer, prostate cancer, lymphoma/myeloma), no visceral metastases, and long-course radiotherapy. On multivariate analysis, absence of visceral metastases and radiation schedule maintained significance. On univariate analysis, improved survival was associated significantly with female sex, favorable histology, no visceral or other bone metastases, good performance status, being ambulatory before radiotherapy, longer interval between tumor diagnosis and MSCC, and slower development of motor deficits before radiotherapy. Long-course radiotherapy showed a trend. On multivariate analysis, histology, visceral metastases, other bone metastases, ambulatory status before radiotherapy, interval between tumor diagnosis and MSCC, and time of developing motor deficits maintained significance. CONCLUSION Poorer local control after radiotherapy for MSCC is associated with visceral metastases and short-course radiotherapy. Long-course radiotherapy seems preferable for patients with more favorable prognoses, given that these patients may live long enough to develop MSCC recurrences. Long-term survival after radiotherapy for MSCC may be predicted if several prognostic factors are considered.

PURPOSE To investigate prospectively the prognostic value of the time of developing motor deficits before radiation therapy (RT) for post-treatment functional outcome in metastatic spinal cord compression. METHODS AND MATERIALS From November 1998 until October 1999, 57 patients were included. Two subgroups were formed according to the time of developing motor deficits before RT: 1-14 days (n = 29) and > 14 days (n = 28). Therapeutic effect on motor function was evaluated by an 8-point scale directly, 6, 12, and 24 weeks after RT. Patients with rapid deterioration of motor function within 48 h before RT (n = 14) were evaluated separately. RESULTS Directly after RT, 26/28 patients (93%) of the group developing motor deficits > 14 days showed improvement of motor function, in comparison to 3/29 patients (10%) of the group 1-14 days (p < 0.001). Deterioration rates were 0% (> 14 days) and 45% (1-14 days). In patients with rapid deterioration of motor function within 48 h before RT, prognosis was poor (improvement 0%, no change 43%, deterioration 57%). Results were comparable 6, 12, and 24 weeks after RT. CONCLUSION A slower development of motor deficits before RT predicts a better post-treatment functional outcome. In patients with rapid deterioration of motor function within 48 h before RT, prognosis was extraordinarily poor. These results support the findings of our preceding retrospective analysis.

Hintergrund. Die simultane Radiochemotherapie hat das Ziel, die lokoregionäre Tumorkontrolle zu erhöhen und die Rate an Fernmetastasen zu senken. Therapieregimes, die Cisplatin/5-FU enthalten, sind allgemein als Standardtherapie bei fortgeschrittenen Kopf-Hals-Karzinomen anerkannt. Die meisten Studien berichten über interessante Ansprechraten und Überlebensraten, gleichzeitig aber auch über eine beträchtliche Mukosatoxizität. Taxol zeigte in den bisherigen Studien sowohl in der Mono- als auch in der Kombinationstherapie eine bemerkenswerte Aktivität bei Kopf-Hals-Karzinomen. In der vorliegenden ambulanten Phase-II-Studie wurde die Kombination von Taxol, Carboplatin und Strahlentherapie bis 40 Gy als neoadjuvantes Konzept bei fortgeschrittenen, operablen Mundhöhlen- und Oropharynxkarzinomen (Stadium III/IV) geprüft. Patienten und Methode. Im Zeitraum von Mai 1998–Oktober 2000 wurden insgesamt 53 Patienten gemäß Studienprotokoll rekrutiert und erhielten wöchentlich Taxol (40 mg/m2) und Carboplatin (AUC 1,5) für 5 Zyklen mit simultaner Strahlentherapie (40 Gy) in konventioneller Fraktionierung. Innerhalb von 3–4 Wochen nach Abschluss der Radiochemotherapie erfolgte die Resektion des Primärtumors und der regionären Halslymphknoten. Ergebnisse. 52 Patienten waren bezüglich Toxizität und Ansprechrate auswertbar. Komplettremissionen wurden bei 31/52 Patienten (CR 60%), partielle Remissionen bei 21/52 Patienten (40%) beobachtet. Histopathologische Komplettremissionen im Resektat wurden bei 30/52 Patienten (pCR 58%) gefunden. Die 1-, 2- und 3-Jahres-Überlebensrate beträgt 84%. Schlussfolgerung. Die vorliegenden Ergebnisse zeigen beeindruckende klinische und pathologische Remissionsraten einer simultanen Radiochemotherapie mit Taxol/Carboplatin als präoperatives Behandlungskonzept bei fortgeschrittenen Mundhöhlen- und Oropharynxkarzinomen. Purpose. The purpose of simultaneous chemoradiotherapy is to increase local-regional control and to decrease the incidence of distant metastases. Regimens containing cisplatin/5-FU chemotherapy are widely accepted as standard treatment in advanced head and neck cancer. Most studies reported promising response and survival data, but also severe mucosal toxicity. In recent years the newly developed drug Taxol demonstrated interesting activity in head and neck cancer as a single agent as well as in combination drug regimens. In the present outpatient phase II trial, we investigated the combination of Taxol/carboplatin with 40 Gy radiotherapy in a neoadjuvant setting of operable stage III/IV squamous cell carcinoma of the oral cavity and oropharynx. Patients and methods. Fifty-three patients were enrolled in this trial during the period from May 1998 to October 2000 and received five cycles weekly of Taxol (40 mg/m2) and carboplatin (AUC 1,5) with conventional radiotherapy (40 Gy). Within 3–4 weeks after chemoradiotherapy resection of the primary tumor and the regional neck nodes was performed. Results. Fifty-two patients were evaluable for toxicity and response. Complete response was observed in 31 of 52 patients (CR 60%), and partial remission was seen in 21 of 52 patients (PR 40%). In 30 of 52 patients complete pathologic response (pCR 58%) was documented in the resection specimens. The 1-, 2-, and 3-year overall survival rate was calculated as 84%. Conclusion. Our present results demonstrated impressive clinical and pathological response rates of concurrent Taxol/carboplatin and radiotherapy as a preoperative treatment modality in advanced oral and oropharyngeal cancer.

Hintergrund: Bei Patienten mit unbekanntem Primärtumor wird zwischen einem lokal begrenzten und einem disseminierten Stadium unterschieden. Bei lokal begrenzter Manifestation beträgt die mediane Überlebenszeit 20, bei Disseminierung 7 Monate. Nach diagnostischen Maßnahmen wie MRT oder Endoskopie liegen die Detektionsraten für den Primärtumor auch heute noch unter 25%. In der vorliegenden Analyse wurde neben die Bedeutung der PET-Befunde für die Detektion des Primärtumors und einer möglichen Disseminierung auch deren therapeutische Relevanz untersucht. Patienten und Methode: Zwischen März 1998 und Februar 2001 wurden 52 Patienten, 18 Frauen und 34 Männer, mit unbekanntem Primärtumor in die Studie eingeschlossen. Bei Erstdiagnose ergab sich in 43 Fällen ein lokal begrenztes (35-mal ein lymphonodales, achtmal ein viszerales), in neun Fällen ein disseminiertes Stadium. Nach median sieben (Bereich drei bis elf) diagnostischen Untersuchungen ohne Detektion des Primärtumors wurde die PET mit Fluor-18-Fluorodeoxyglucose durchgeführt. Ergebnisse: Bei 31/52 Patienten (60%) wurde im PET-Befund eine mögliche Lokalisation des Primärtumors beschrieben, in 21/52 Fällen (40%) auch bestätigt. Bei 16/43 Patienten (37%) mit zunächst lokal begrenztem Stadium wurde eine Disseminierung trotz vorausgegangener intensiver Diagnostik erstmals anhand des PET-Befundes diagnostiziert. Insgesamt war der PET-Befund bei 33/52 Patienten (63%) von wesentlicher Relevanz für das endgültige therapeutische Prozedere, bei zunächst lokal begrenztem Erkrankungsstadium bei 30/43 Patienten (70%). Schlussfolgerung: Bei Patienten mit unbekanntem Primärtumor ist die PET von großer Bedeutung, und zwar nicht nur für die Detektion des Primärtumors, sondern bei zunächst lokal begrenztem Stadium auch für den Nachweis einer möglichen Disseminierung. Aus den PET-Befunden ergeben sich häufig relevante Konsequenzen für das therapeutische Vorgehen.Background: In patients with cancer of unknown primary median survival for localized disease in 20, for disseminated disease 7 months. After diagnostic procedures including MRI or endoscopy, the primary tumor is detected in less than 25%. In the study presented here the value of PET for detection of the primary tumor and a possible dissemination has been investigated and related to therapeutic regimens. Patients and Methods: Between May 1998 and February 2001 a total of 52 patients with CUP syndrome, 18 females and 34 males, have been included. At first diagnosis, stage of disease was localized in 43 patients (35 lymphonodal, eight visceral), and disseminated in nine patients (Table 1). After a median of seven (range three to eleven) diagnostic procedures without detection of the primary tumor (Table 2) PET with fluorine-18-fluorodeoxyglucose was performed. Results: Due to the PET result a primary tumor was suggested in 31/52 patients (60%), and confirmed in 21/52 patients (40%). In 16/43 patients (37%) with initially (before PET) localized disease dissemination was detected by PET only, despite various preceding diagnostic procedures (Figure 1). Overall, in 33/52 patients (63%) the PET result had major impact on selection of an individual treatment (Table 3), in case of initially localized disease in 30/43 patients (70%). Conclusion: In patients with CUP the PET result is not only of great value for detection of the primary tumor, but in case of initially localized disease also for diagnosis of a possible dissemination. The PET result often has relevant influence on therapeutic management.
