  abstract  = {Gastrointestinale Lymphome des MALT sind heute als eigenst{\"a}ndige Entit{\"a}t anerkannt. Sie zeichnen sich durch morphologische, molekularbiologische, {\"a}tiopathogenetische und biologische Besonderheiten aus, die sie von den nodalen Lymphomen abgrenzen lassen. Im Rahmen der W{\"u}rzburger Multicenterstudie „Gastrointestinale Lymphome II" soll die Frage gekl{\"a}rt werden, ob in den lokalisierten Stadien I und II prim{\"a}rer Magenlymphome unter Ber{\"u}cksichtigung der posttherapeutischen Lebensqualit{\"a}t der operativen oder einer prim{\"a}r 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 {\"u}beraus hohe Remissionsraten in den Stadien EI und EII (CR um 90\%). Unterschiede zwischen den Behandlungsmethoden konnten, evtl. auch bedingt durch die kleinen Gruppengr{\"o}ßen, nicht nachgewiesen werden. Insgesamt verstarben sechs Patienten, die sich in etwa gleichm{\"a}ßig auf die Gruppen verteilten. Die Auswertung der Frageb{\"o}gen zur Lebensqualit{\"a}t ergab gem{\"a}ß SF-36 durchaus hohe Werte zur posttherapeutischen Lebensqualit{\"a}t. Eine Differenzierung der Patienten nach Behandlungsmethode oder Malignit{\"a}tsgrad (low, high grade) war nicht m{\"o}glich. Der Lebensqualit{\"a}tsindex nach Troidl ließ einen pr{\"a}-post-therapeutischen Vergleich zu: Betrachtet man die Kombination von Therapie und Malignit{\"a}tsgrad, so fallen konservativ therapierte Patienten (unabh{\"a}ngig vom Malignit{\"a}tsgrad) durch deutlich ansteigende Lebensqualit{\"a}t auf. Es l{\"a}sst sich festhalten, dass bei prim{\"a}r gastrointestinalen Lymphomen sowohl mit operativem als auch konservativem Vorgehen hohe Remissionsraten erzielt werden k{\"o}nnen. Jedoch sind im Hinblick auf Organerhalt und die h{\"o}here post-therapeutische Lebensqualit{\"a}t die prim{\"a}re Radio- und/oder Chemotherapie dem operativen Vorgehen vorzuziehen.},

  abstract  = {Background Multimodal treatment strategies - perioperative chemotherapy (CTx) and radical surgery - are currently accepted as treatment standard for locally advanced gastric cancer. 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.},

  abstract  = {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.},
