TY - THES A1 - Schramm, Stefanie T1 - Überleben und Lebensqualität sprechen für ein konservatives Therapiekonzept bei Patienten mit Magenlymphomen : Ergebnisse einer prospektiven randomisierten Studie T1 - Outcome & quality of live favour a conservative treatment of patients with gastric lymphoma : results of a prospective randomised study N2 - Gastrointestinale Lymphome des MALT sind heute als eigenständige Entität anerkannt. Sie zeichnen sich durch morphologische, molekularbiologische, ätiopathogenetische und biologische Besonderheiten aus, die sie von den nodalen Lymphomen abgrenzen lassen. Im Rahmen der Würzburger Multicenterstudie „Gastrointestinale Lymphome II“ soll die Frage geklärt werden, ob in den lokalisierten Stadien I und II primärer Magenlymphome unter Berücksichtigung der posttherapeutischen Lebensqualität der operativen oder einer primär konservativen Therapie (Chemo- oder Radiotherapie) Vorzug gegeben werden soll. Von 1998 bis 2002 wurden dazu 49 Patienten mit neu diagnostiziertem niedrig- (n=19) oder hochmalignen (n=30) NHL des Magens in die Studie eingeschlossen. Nach zentraler Randomisierung wurden die Patienten mit low grade NHL der Operation (n=10) oder der Radiotherapie (n=9) zugeteilt. Die Patienten mit high grade NHL erhielten Operation plus Chemotherapie (n=16) oder alleinige Chemotherapie (n=14). Das mediane follow up betrug 74 Monate. Sowohl das operative als auch das konservative Vorgehen zeigten bei beiden Lymphomhistologien überaus hohe Remissionsraten in den Stadien EI und EII (CR um 90%). Unterschiede zwischen den Behandlungsmethoden konnten, evtl. auch bedingt durch die kleinen Gruppengrößen, nicht nachgewiesen werden. Insgesamt verstarben sechs Patienten, die sich in etwa gleichmäßig auf die Gruppen verteilten. Die Auswertung der Fragebögen zur Lebensqualität ergab gemäß SF-36 durchaus hohe Werte zur posttherapeutischen Lebensqualität. Eine Differenzierung der Patienten nach Behandlungsmethode oder Malignitätsgrad (low, high grade) war nicht möglich. Der Lebensqualitätsindex nach Troidl ließ einen prä-post-therapeutischen Vergleich zu: Betrachtet man die Kombination von Therapie und Malignitätsgrad, so fallen konservativ therapierte Patienten (unabhängig vom Malignitätsgrad) durch deutlich ansteigende Lebensqualität auf. Es lässt sich festhalten, dass bei primär gastrointestinalen Lymphomen sowohl mit operativem als auch konservativem Vorgehen hohe Remissionsraten erzielt werden können. Jedoch sind im Hinblick auf Organerhalt und die höhere post-therapeutische Lebensqualität die primäre Radio- und/oder Chemotherapie dem operativen Vorgehen vorzuziehen. N2 - Primary gastric MALT lymphomas have come to be considered as a separate tumor entity with specific histological and biological features. As part of the multicenter study „Gastrointestinale Lymphome II“ the question should be solved whether gastric MALT lymphomas in localized stage I and II should undergo either primary surgical or conservative (radio- or chemotherapy) treatment taking into consideration the post-therapeutic quality of life. From 1998 to 2002 49 patients with newly diagnosed low (n=19) and high grade (n=30) gastric lymphoma were enrolled in the multicenter study. After central randomisation patients with low grade NHL were referred to operation (n=10) or radiotherapy (n=9). Patients with high grade NHL underwent gastric surgery plus chemotherapy (n=16) or primary chemotherapy (n=14). The median follow up-time amounted to 74 months. Both surgical and conservative treatment showed very high remission rates in stage I and II (CR about 90%) for either lymphoma histology. Differences between the two therapy strategies could not be detected, possibly due to the small size of the groups. A total of six patients deceased, about evenly distributed among the both groups. The evaluation of the SF-36 qualitiy of life questionnaires proved quite a high post-therapeutic quality of life. It was not possible to differentiate between the patients with respect to either treatment or grade (low, high grade). According to the Troidl index the pre-post quality of life could be compared. Looking at the combination of therapy and grade conservatively treated patients (regardless of the grade) showed a considerably increasing quality of life. To sum up, it can be said that in primary gastric MALT lymphoma high remission rates can be achieved with both surgery and conservative therapy. But with regard to organ preservation and higher post-therapeutic quality of life primary radio- and/or chemotherapy should be preferred to surgical treatment.

However, the role of adjuvant postoperative CTx (postCTx) in addition to neoadjuvant preoperative CTx (preCTx) in this setting remains controversial. Methods Between 4/2006 and 12/2013, 116 patients with locally advanced gastric cancer were treated with preCTx. 72 patients (62 %), in whom complete tumor resection (R0, subtotal/total gastrectomy with D2-lymphadenectomy) was achieved, were divided into two groups, one of which receiving adjuvant therapy (n = 52) and one without (n = 20). These groups were analyzed with regard to survival and exclusion criteria for adjuvant therapy. Results Postoperative complications, as well as their severity grade, did not correlate with fewer postCTx cycles administered (p = n.s.). Long-term survival was shorter in patients receiving postCTx in comparison to patients without postCTx, but did not show statistical significance. In per protocol analysis by excluding two patients with perioperative death, a shorter 3-year survival rate was observed in patients receiving postCTx compared to patients without postCTx (3-year survival: 71.2 % postCTx group vs. 90.0 % non-postCTx group; p = 0.038). Conclusion These results appear contradicting to the anticipated outcome. While speculative, they question the value of post-CTx. Prospectively randomized studies are needed to elucidate the role of postCTx.

T1 - CA19-9 decrease at 8 weeks as a predictor of overall survival in a randomized phase III trial (MPACT) of weekly nab-paclitaxel plus gemcitabine versus gemcitabine alone in patients with metastatic pancreatic cancer JF - Annals of Oncology N2 - Background A phase I/II study and subsequent phase III study (MPACT) reported significant correlations between CA19-9 decreases and prolonged overall survival (OS) with nab-paclitaxel plus gemcitabine (nab-P + Gem) treatment for metastatic pancreatic cancer (MPC). CA19-9 changes at week 8 and potential associations with efficacy were investigated as part of an exploratory analysis in the MPACT trial. Patients and methods Untreated patients with MPC (N = 861) received nab-P + Gem or Gem alone. CA19-9 was evaluated at baseline and every 8 weeks. Results Patients with baseline and week-8 CA19-9 measurements were analyzed (nab-P + Gem: 252; Gem: 202). In an analysis pooling the treatments, patients with any CA19-9 decline (80%) versus those without (20%) had improved OS (median 11.1 versus 8.0 months; P = 0.005). In the nab-P + Gem arm, patients with (n = 206) versus without (n = 46) any CA19-9 decrease at week 8 had a confirmed overall response rate (ORR) of 40% versus 13%, and a median OS of 13.2 versus 8.3 months (P = 0.001), respectively. In the Gem-alone arm, patients with (n = 159) versus without (n = 43) CA19-9 decrease at week 8 had a confirmed ORR of 15% versus 5%, and a median OS of 9.4 versus 7.1 months (P = 0.404), respectively. In the nab-P + Gem and Gem-alone arms, by week 8, 16% (40/252) and 6% (13/202) of patients, respectively, had an unconfirmed radiologic response (median OS 13.7 and 14.7 months, respectively), and 79% and 84% of patients, respectively, had stable disease (SD) (median OS 11.1 and 9 months, respectively). Patients with SD and any CA19-9 decrease (158/199 and 133/170) had a median OS of 13.2 and 9.4 months, respectively. Conclusion This analysis demonstrated that, in patients with MPC, any CA19-9 decrease at week 8 can be an early marker for chemotherapy efficacy, including in those patients with SD. CA19-9 decrease identified more patients with survival benefit than radiologic response by week 8.
