RESUMEN
The aim of this report is to investigate the activity of ramucirumab in combination with paclitaxel in patients with metastatic gastric cancer (GC) and lung metastases. We retrospectively reviewed clinical data from patients with GC treated in second line with ramucirumab and paclitaxel according to the presence or not of lung metastases. Thirty-one patients were eligible. Five (16.1%) patients had lung metastases. The median progression-free survival was 156 days in patients without lung metastases compared with 54 days in patients with lung metastases. The median survival also showed a trend in favour of patients without lung metastases. Despite the small number of patients and the retrospective nature of the data, our analysis showed relatively poor efficacy of ramucirumab plus paclitaxel as a second-line treatment in patients with lung metastases from GC. Further studies are required to evaluate novel treatments in this subset of patients.

BACKGROUND: High tumor infiltrating lymphocytes (TILs) density was previously shown to be associated with favorable prognosis for patients with colon cancer (CC). However, the impact of TILs on overall survival (OS) of stage II CC patients who received adjuvant chemotherapy (ADJ) or not (no-ADJ) is unknown. We assessed the prognostic value of CD3+ TILs in stage II CC patients according to whether they had ADJ or not. METHODS: Patients treated with curative surgery for stage II CC (2002-2013) were selected from the Santa Maria alle Scotte Hospital registry. TILs at the invasive front, center of tumor, and stroma were determined by immunohistochemistry and manually quantified as the rate of TILs/total tissue areas. High TILs (H-TILs) was defined as >20%. Patients were categorized as high or low TILs (L-TILs) and ADJ or no-ADJ. RESULTS: Of the 678 patients included, 137 (20%) received ADJ and 541 (80%) did not. The distribution of the 4 groups were: 16% (L-TIL/ADJ), 64% (L-TIL/no-ADJ), 5% (H-TIL/ADJ), 15% (H-TIL/no-ADJ). Compared to H-TILs/no-ADJ, ADJ patients showed a significantly increased OS (P<.01) regardless of the TILs rate whereas L-TILs/no-ADJ had significantly decreased OS and higher risk of death (HR=1.41; 95% CI, 1.06-1.88; P<.0001). On multivariable analysis, the unfavorable prognostic value of L-TILs (vs. H-TILs) for no-ADJ patients was confirmed (HR=1.36; 95% CI 1.02, 1.82; P=.0373). CONCLUSION: Low CD3+ TILs rate was associated with shorter OS in those with stage II colon cancer who did not receive adjuvant therapy. Low CD3+ TILs could be considered an additional risk factor for still ADJ-untreated stage II CC patients, which could facilitate clinical decision making.
