Chemoradiotherapy (CRT) of the primitive could allow sufficient local control in order to avoid major and sometimes mutilating surgery. Dose escalation during CRT could increase this local control. The aim of this study was to evaluate the feasibility and tolerance of a CRT with radiation dose escalation delivered in intensity modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB), in metastatic low and middle rectal cancers.MethodsThis multicenter phase I study included six patients treated for unresectable synchronous metastatic low and middle rectal adenocarcinoma in two dose levels. Radiotherapy was delivered using IMRT with SIB. The dose escalation was 52.5 Gy (level 1) and 56.25 Gy (level 2) in the primary tumor, in 25 fractions of 2.1 Gy and 2.25 Gy, respectively. High-risk clinical target volume (CTV) and low-risk CTV received respectively 50 Gy and 45 Gy in 25 fractions in the two levels. Concomitant chemotherapy was oral capecitabine and CRT was performed after four cycles of mFOLOX6 chemotherapy. The dose-limiting toxicity (DLT) was defined by a toxicity requiring the interruption of radiotherapy for more than five consecutive fractions.ResultsAll six patients received the full course of treatment at scheduled doses. No patients had acute toxicity requiring interruption of radiotherapy therefore no DLT has been reported. No patients had acute toxicity ≥ 3. Concerning late toxicity, three patients experienced grade 3. After CRT, four patients had a partial response and one patient had a complete clinical response. Two patients were considered in local progression at 9.4 months and 20.4 months of inclusion.ConclusionsDose escalation at 56.25 Gy in the tumor lesion was possible with good acute tolerance. It needs to be evaluated in a larger study. It could allow sufficient local control in order to avoid mutilating surgery in these metastatic patients.Trial registrationNCT03634202.

The measurement of serum Vascular Endothelial Growth Factor (VEGF) has proven to be a useful prognostic\u0000factor in gastric cancer, but it also could be a predictive factor for peritoneal metastases since the VEGF signalling pathway is directly\u0000involved in the development of peritoneal metastases.\u0000Methods: This is a retrospective study from 2005 to 2017. We reviewed the peritoneal recurrence pattern of a cohort of 59 gastric\u0000cancer patients in whom serum VEGF was measured before surgery and after completion of adjuvant treatment\u0000Results: Preoperative serum VEGF (pre-VEGF) level was identified as an independent prognostic factor for developing peritoneal\u0000metastases. The optimal cut-off value of pre-VEGF levels was 507 pg/mL, which presented a sensitivity of 66 % and a specificity of\u000078% to predict the development of peritoneal metastases. Patients with high pre-VEGF levels (>507 pg/mL) were at greater risk of\u0000developing peritoneal metastases than patients with low pre-VEGF levels (<507 pg/mL) (p=0.023).\u0000Conclusions: VEGF plays a crucial role in the development of peritoneal metastases, and serum VEGF meets the requirements of a\u0000potential predictive marker for peritoneal carcinomatosis.

Methods : 148 patients with resectable stage T4 colorectal cancer who underwent surgery in the first Affiliated Hospital of Sun Yat-sen University between August, 1994 and December, 2005 were retrospectively analyzed. Univariate and multivariate analyses of associations between clinicopathological variables and survival were analyzed using the Cox regression model. Results: At the end of December of 2010 or death, the 5-year and 10 years OS rates were 49.0% and 32.2% respectively, the median OS was 25 months. The disease free survival rates (DFS) at 5 and 10 years were 44.2% and 30.3% respectively. In univariate analysis, patients with postoperative pathology lymph node metastasis was associated with the prognosis of patients with OS (all P< 0.01), postoperative adjuvant therapy failed to improve OS and DFS (P>0.05). Postoperative pathology lymph node metastasis was associated with DFS too (all P< 0.01).

In this CRC subtype, the response rate to anti-PD-(L)1 antibodies is high thanks to\u0000the presence of neoantigens and tumor-infiltrating lymphocytes that are associated with the anti-tumor immune response.

In addition, recent studies found that DNA damage induces PD-L1 expression.

To date, no study has reported the trajectory of the QOL throughout the clinical course of a patient with advanced malignancy. As hospitalization is considered a predictor of QOL, we retrospectively analyzed the trajectory of hospitalization in patients with incurable gastric cancer throughout the clinical course. Methods: The data of 85 patients with incurable gastric cancer were collected, including age, sex, Eastern Cooperative Oncology Group (ECOG) Performance Status (PS), treatment, histology, sites of metastases at first consultation, planned and unplanned hospitalization throughout the clinical course , and overall survival (OS). We ranked the patients by OS and hospitalization using a hierarchical clustering analysis. Results: Three clusters were identified corresponding to short, intermediate, and long OS/hospitalization (Clusters 1, 2, and 3, respectively). Patients in Cluster 3 were more likely to have an ECOG PS of 0–2 and receive palliative chemotherapy than the other clusters. No other differences in histology, age, sex, and or extra-peritoneal metastasis sites were observed between the three groups. In Cluster 3, planned hospitalization accumulated gradually during the early clinical phase, while unplanned hospitalization accumulated rapidly in later phases. Conclusions: No specific characteristics were associated with short, intermediate, and long OS/hospitalization. Patients in the long OS/hospitalization group exhibited a rapid accumulation of unplanned hospitalization during the latter clinical course.
