AbstractTo construct and validate a nomogram to predict the overall survival (OS) of colorectal signet ring cell carcinoma (SRCC). The potentially eligible cases were obtained against the SEER database from 2004 to 2015. Log-rank test and Cox analysis were conducted to identify the independent prognostic factors for predicting OS. The identified prognostic factors were later integrated for the construction of an OS prediction nomogram. Altogether 2904 eligible cases were identified, and the median survival time was 18 (range: 0–155) months. As suggested by multivariate analysis, age, primary site, grade, tumor size, T stage, N stage, M stage, surgery, lymph node dissection and chemotherapy were identified as the independent factors for predicting OS. Afterwards, the above variables were incorporated into the nomogram. The C-index indicated better discriminatory ability of the nomogram than AJCC 8th TNM staging and SEER summary stage systems (both P < 0.001). Calibration plots further showed good consistency between the nomogram prediction and actual observation. The time independent area under the curves (tAUCs) for 3-year and 5-year OS in nomogram were larger than AJCC and SEER summary stage system. The constructed nomogram could potentially predict the survival of colorectal SRCC individuals.

We do not know the clinical and prognostic factors that influence the survival of patients with gastric signet ring cell carcinoma (SRC). Therefore, a retrospective review was undertaken of 219 patients with SRC who had undergone gastrectomy between January 2009 and December 2012 in our hospital. Patient age, sex, TNM stage, vessel carcinoma embolus, perineural invasion, tumor site and operation type, postoperative chemotherapy, and five-year overall survival were recorded and evaluated. In our study, 93 cases (42.5%) were signet ring cell carcinoma only, and 126 cases (57.5%) were signet ring cell carcinoma coexisting with other components (such as adenocarcinoma or mucus adenocarcinoma). Eighty-three patients were female, 136 were male, 46 occurred at the gastroesophageal junction (21.0%), 63 at the fundus/body (28.8%), 80 were antrum/pylorus (36.5%), and 30 were whole stomach (13.7%). The prognosis of gastric antrum/ pylorus cancer was the best (P < 0.05). There were 133 patients (60.7%) with stage III, and the single factor analysis showed that the earlier the stage, the better the prognosis. The overall five-year survival rate was 30.1% in all patients. One-hundred and 41 patients (64.4%) received D2 radical surgery, 64 (29.2%) received D1 radical operation, and 14 (6.4%) received palliative resection, and the patients who received D2 had the best overall survival (P < 0.05). The survival time of the paclitaxel-based regimen in postoperative adjuvant chemotherapy tended to be prolonged. There was no statistical difference in overall survival between the percentage of signet-ring cells and sex. In summary, age, tumor stage, and surgical resection combined with D2 lymphadenectomy were independent prognostic factors for SRC. Adjuvant chemotherapy with a paclitaxel-based regimen may improve the survival of patients with SRC.

Abstract Background: The objective of this study was to assess the clinical efficacy of radiotherapy combined with surgery for locally advanced gastric signet-ring-cell carcinoma (GSRCC). Methods: Clinical data of patients with locally advanced GSRCC diagnosed by postoperative pathology from 2000-2016 were collected from the US Surveillance, Epidemiology and End Results (SEER) database. All the enrolled patients were divided into three groups according to treatment type: surgery alone (S; N=727), surgery with preoperative radiotherapy (RT+S; N=138), surgery with postoperative radiotherapy (S+RT; N=548). Results: The median overall survival (OS) time in S, RT+S and S+RT group was 19, 26 and 33 months, respectively; the overall survival (OS) rate was 19.5%, 26.9% and 34.0%, respectively; the median cancer-specific survival (CSS) time was 29, 31 and 43 months, respectively; and the CSS rate was 32,4%, 35.3% and 43.6%, respectively. After performing propensity score matching (PSM), it was found that the OS rate was significantly lower in S group than in RT+S or S+RT group (all P<0.05) and the CSS rate was lower in the SA group than in the S+RT group (P<0.0001) while there was no significant difference between S and RT+S groups. The OS and CSS were not significantly different between RT+S and S+RT groups. Cox multivariate analysis showed that radiotherapy was an independent prognostic factor for OS and CSS of locally advanced GSRCC.Conclusions: Compared to surgery alone, surgery combined with preoperative or postoperative radiotherapy is beneficial to the long-term survival of patients with locally advanced GSRCC.

Abstract Objective: To evaluate the prognostic value of age on colorectal signet ring cell carcinoma (SRCC) and identify the prognosis factors of patients aged ≥ 65 years.Methods: Patients were recruited from the Surveillance, Epidemiology, and End Results (SEER) database. We ensured that all characteristics were well balanced through adopting the propensity score matching (PSM) method. In addition, the prognostic factors were evaluated by the Cox proportional hazardous model.Results: Altogether 3305 cases were enrolled, including 1564 in elderly group (aged ³65 years). As a result, more patients were female, unmarried, white, earlier AJCC stage, tumor size ≤5cm, grade III/IV and located in cecum–transverse colon in the elderly group; whereas significant fewer patients received chemotherapy and radiotherapy. After 1:1 PSM analysis, each group contained 1032 cases. As discovered by Kaplan-Meier analysis, the elderly group was associated with remarkably dismal survival compared with the younger group after PSM analysis (P=0.0091).Moreover, grade, primary site, AJCC stage, tumor size, surgery and chemotherapy were identified as the independent prognostic factors for the elderly patients.Conclusion: The prognosis of colorectal SRCC aged ≥ 65 years was worse than the younger patients. We may need strengthen the chemotherapy of the eldly colorectal SRCC.

Primary signet ring cell/histiocytoid carcinoma of the eyelid is a rare ocular malignancy and its diagnosis is often delayed. This neoplasm presents as an insidious, diffusely infiltrative mass in the periocular area that later infiltrates the orbit. An exenteration is usually indicated; however, nearly one-third of patients develop local recurrence or metastasis. Morphologically, it resembles signet ring cell carcinoma of the stomach and breast, raising the possibility of mutations in CDH1, the gene encoding E-cadherin. To determine whether primary signet ring cell/histiocytoid carcinoma harbors the CDH1 mutation or other actionable mutations, we analyzed the tumor tissue via next-generation sequencing. We identified only one case of primary signet ring cell carcinoma of the eyelid with adequate DNA quality for sequencing from the pathological archive during the period 2000 to 2020. A comprehensive evaluation including histopathology, immunohistochemistry, and next-generation sequencing assay was performed on tumor tissue. Immunohistochemically, the tumor exhibited E-cadherin membranous staining with the aberrant cytoplasmic staining of β-catenin. Using next-generation sequencing, we demonstrated the mutation in the CDH1 gene. In addition, other clinically actionable mutations including ERBB2 and PIK3CA were also detected. The alterations in other actionable genes indicate a need for larger studies to evaluate the pathogenesis and potential therapies for primary signet ring cell/histiocytoid carcinoma of the eyelid.

Pseudo-signet ring parietal cell vacuolation has been described as a mimic of invasive signet ring cell carcinoma. Moreover, signet ring cell carcinoma has been described in a fundic gland polyp. This case demonstrates parietal cell vacuolation in a fundic gland polyp in a patient on a long-term proton pump inhibitor.
