Abstract:
e15164 Background: Unresectable locally advanced adenocarcinoma (AGC) of the stomach is associated with poor prognosis due to the lack of effective treatment. Neoadjuvant chemotherapy (NAC) has drawn more attention to the treatment of locally AGC in the current multidisciplinary treatment model. Paclitaxel and capecitabine (PX) has been used in palliative setting with good response rates but its role in a neoadjuvant setting is not well established. This phase II study was performed to evaluate the efficacy and safety of neoadjuvant PX chemotherapy in patients with unresectable locally AGC. Methods: Patients with AGC, clinically unresectable because of local invasion and/ or conglomerated regional lymph nodes (station 7, 8, and 9) metastasis on based on laparoscopic staging, were enrolled. PX consisted of paclitaxel 175 mg/m 2 i.v. on day 1, and capecitabine 835 mg/m 2 twice daily p.o. on days 1–14 every 21 days. After three cycles of NAC, patients with clinically resectable AGC underwent surgical resection. Results: This trial was stopped for poor accrual after 18 patients were enrolled; 50% patients had tumors located in the proximal third of the stomach. Seventeen patients finished three cycles of chemotherapy. The overall response rate was 41.2% (7/17 cases), of which 71.4% (10/14 cases) metabolic response. Fourteen (77.8%) of the 18 patients enrolled underwent surgery, and 12 (85.7%) had an R0 resection. Pathological complete response was observed in one (7.1%) of patients. Toxicity was mild to moderate and there were no treatment-related deaths and no major surgical complications. With a median follow-up of 28.6 months (range 6.4-38.4 months), the 2-year survival rate for all patients was 71.1%. Subgroup analysis found R0 resection (35.7 months vs. 20.6 months, P= 0.005) and patients with pathologic N downstaging (P 〈 0.001) to have improved overall survival. Conclusions: Neoadjuvant chemotherapy with PX shows promising results in unresectable locally AGC patients without increased morbidity and mortality. Neoadjuvant PX may permit a larger chance of curative resection in unresectable locally AGC patients.
