1Metastatic pattern in esophageal and gastric cancer:Influenced by site and histology显示文摘BACKGROUND Detailed information on metastatic patterns in of patients with esophageal and gastric cancer is limited.Early recognition of metastases is important to avoid futile locoregional treatments.Furthermore,knowledge on metastatic patterns is necessary for further development of personalized treatment modalities.AIM To gain insight into the metastatic pattern of gastroesophageal cancer.METHODS A nationwide retrospective autopsy study of 3876 patients with adenocarcinoma(AC)or squamous cell carcinoma(SCC)of the esophagus or stomach between 1990 and 2017 was performed.Only patient with metastases were included for analysis.The metastatic pattern was analyzed according to the primary tumor location and histological subtype.RESULTS Metastatic disease was found in 268 esophageal and 331 gastric cancer patients.In esophageal cancer,the most common metastatic locations were liver(56%),distant lymph nodes(53%)and lung(50%).Esophageal AC showed more frequently metastases to the peritoneum and bone compared with esophageal SCC.In gastric cancer,the most common metastatic locations were distant lymph nodes(56%),liver(53%)and peritoneum(51%).Intestinal-type AC of the stomach showed metastases to the liver more frequently,whereas metastases to the bone,female reproductive organs and colorectum were observed more frequently in diffuse-type gastric AC.CONCLUSION This study showed differences in metastatic patterns of patients with esophageal and gastric cancer according to the primary tumor location and histological subtype.Moniek HP Verstegen Mitchell Harker Carlijn van de Water Jolanda van Dieren Niek Hugen Iris D Nagtegaal Camiel Rosman Rachel S van der Post 2020World Journal of Gastroenterology2020,26,39:9
2Adjuvant therapy sparing in rectal cancer achieving complete response after chemoradiation显示文摘AIM:To evaluate the long-term results of conventional chemoradiotherapy and laparoscopic mesorectal excision in rectal adenocarcinoma patients without adjuvant therapy.METHODS:Patients with biopsy-proven adenocarcinoma of the rectum staged cT3-T4 by endoscopic ultrasound or magnetic resonance imaging received neoadjuvant continuous infusion of 5-fluorouracil for five weeks and concomitant radiotherapy.Laparoscopic surgery was planned after 5-8 wk.Patients diagnosed with ypT0N0 stage cancer were not treated with adjuvant therapy according to the protocol.Patients with ypT1-2N0 or ypT3-4 or N+were offered 5-fluorouracil-based adjuvant treatment on an individual basis.An external cohort was used as a reference for the findings.RESULTS:One hundred and seventy six patients were treated with induction chemoradiotherapy and 170underwent total mesorectal excision.Cancer staging of ypT0N0 was achieved in 26/170(15.3%)patients.After a median follow-up of 58.3 mo,patients withypT0N0 had five-year disease-free and overall survival rates of 96%(95%CI:77-99)and 100%,respectively.We provide evidence about the natural history of patients with localized rectal cancer achieving a complete response after preoperative chemoradiation.The inherent good prognosis of these patients will have implications for clinical trial design and care of patients.CONCLUSION:Withholding adjuvant chemotherapy after complete response following standard neoadjuvant chemoradiotherapy and laparoscopic mesorectal excision might be safe within an experienced multidisciplinary team.Xabier García-Albéniz Rosa Gallego Ralf Dieter Hofheinz Gloria Fernández-Esparrach Juan Ramón Ayuso-Colella Josep Antoni Bombí Carles Conill Miriam Cuatrecasas Salvadora Delgado Angels Ginés Rosa Miquel Mario Pagés Estela Pineda Verónica Pereira Aarón Sosa Oscar Reig Iván Victoria Luis Feliz Antonio María de Lacy Antoni Castells Iris Burkholder Andreas Hochhaus Joan Maurel 2014World Journal of Gastroenterology2014,20,42:5
