Data mining of a public transcriptomic rectal cancer dataset (GSE35452) from the Gene Expression Omnibus, National Center for Biotechnology Information identified the melanophilin (MLPH) gene as the most significant intracellular protein transport-related gene (GO:0006886) associated with a poor response to preoperative chemoradiation. An MLPH immunostain was performed on biopsy specimens from 172 rectal cancer patients receiving preoperative chemoradiation; samples were divided into high- and low-expression groups by H-scores. Subsequently, the correlations between MLPH expression and clinicopathologic features, tumor regression grade, disease-specific survival (DSS), local recurrence-free survival (LRFS), and metastasis-free survival (MeFS) were analyzed. MLPH expression was significantly associated with CEA level (p = 0.001), pre-treatment tumor status (p = 0.022), post-treatment tumor status (p < 0.001), post-treatment nodal status (p < 0.001), vascular invasion (p = 0.028), and tumor regression grade (p < 0.001). After uni- and multi-variable analysis of five-year survival, MLPH expression was still associated with lower DSS (hazard ratio (HR), 10.110; 95% confidence interval (CI), 2.178–46.920; p = 0.003) and MeFS (HR, 5.621; 95% CI, 1.762–17.931; p = 0.004). In conclusion, identifying MLPH expression could help to predict the response to chemoradiation and survival, and aid in personal therapeutic modification.

Despite recent progresses, locally advanced gastric cancer remains a daunting challenge to embrace. Perioperative chemotherapy and D2-gastrectomy depict multimodal treatment of gastric cancer in Europe, shows better results than curative surgery alone in terms of downstaging, micrometastases elimination, and improved long-term survival. Unfortunately, preoperative chemotherapy is useless in about 50% of cases of non-responder patients, in which no effect is registered. Tumor regression grade (TRG) is directly related to chemotherapy effectiveness, but its understanding is achieved only after surgical operation; accordingly, preoperative chemotherapy is given indiscriminately. Conversely, Naples Prognostic Score (NPS), related to patient immune-nutritional status and easily obtained before taking any therapeutic decision, appeared an independent prognostic variable of TRG. NPS was calculated in 59 consecutive surgically treated gastric cancer patients after neoadjuvant FLOT4-based chemotherapy. 42.2% of positive responses were observed: all normal NPS and half mild/moderate NPS showed significant responses to chemotherapy with TRG 1–3; while only 20% of the worst NPS showed some related benefits. Evaluation of NPS in gastric cancer patients undergoing multimodal treatment may be useful both in selecting patients who will benefit from preoperative chemotherapy and for changing immune-nutritional conditions in order to improve patient’s reaction against the tumor.

Background. Tumor regression grade (TRG) is widely used in gastrointestinal carcinoma to evaluate pathological responses to neoadjuvant chemotherapy (NCT), but whether it is an independent prognostic factor is still controversial. The aim of this study is to investigate the value of TRG in locally advanced gastric adenocarcinoma patients who underwent NCT and curative resection. Methods. Pathological regression was reevaluated according to the Mandard TRG. Survival curves were obtained by the Kaplan–Meier method, and differences in overall survival (OS) and disease-free survival (DFS) were compared using the log-rank test. Univariate and multivariate analyses for survival were based on the Cox proportional hazards method. Results. In total, 290 patients were identified in our electronic database. In univariable analysis, TRG was associated with OS (HR=3.822, P≤0.001) and DFS (HR=3.374, P≤0.001). However, in multivariable analysis, TRG was not an independent factor for OS (P=0.231) or DFS (P=0.191). In the stratified analysis, TRG retrieved prognostic significance in patients with the metastasis of lymph node (HR=2.034, P=0.035 for OS; HR=2.220, P=0.016 for DFS), while not in patients with negative lymph node (P=0.296 for OS; P=0.172 for DFS). Conclusions. TRG was not an independent predictor for survival, but the system regained its predicting significance in patients with lymph node metastasis.

UNSTRUCTURED Background: Rectal tumors are important malignancies and prediction of prognosis after neoadjuvant therapy is important to improve the prognosis process. The purpose of this study was to determine therole ofneoadjuvant therapy in lymph node regression and primary rectal tumor as well as its association with prognosis. Methods and materials: In this descriptive study, 40 consecutive patients with rectal tumor who were referred toTaleghani Hospital for surgery from 2011 to 2018 were enrolled. Moreover, theneoadjuvant therapy role in lymph node regression and primary rectal tumor was determined as well as its association with prognosis. Results: The results of this study demonstrate that there was no tumor regression in 20% of patients and it wasalso less than 25%, 25-50%, 50-75%, and complete in 22.5%, 35%, 20%, and 2.5% of the patients,respectively. The lymph node regression was complete in 5% of the patients and it wasalso less than 25% in 20% and more than 25% in 50% of them. In addition, it was with no regression in 25% of the patients. The lymph node regression was related to N stage (P=0.018), primary tumor regression grade (P=0.001), yPT (P=0.008), and yPN (P=0.020); however, it was not related to prognosis (P > 0.05). Conclusions: Totally, according to the obtained results, it can be concluded thatneoadjuvant therapy plays a good role in lymph node regression and primary rectal tumor, but it has no association with prognosis.
