Abstract
INTRODUCTION Splenic malignancies are mostly lymphocytic tumors and splenic metastases are rarer.[1] According to reports, the most common source of splenic metastases include melanoma, tumors of the breast, lung, ovary, colon, stomach, and pancreas.[2,3]. PATIENT CONCERNS This paper reports a 41-year-old male patient who underwent a successful resection of low rectal cancer in our hospital 5 years ago. DIAGNOSIS Three months ago, computed tomography scan revealed a tumor in the spleen, considered as an isolated metastasis. INTERVENTIONS The patient underwent splenectomy and postoperative pathological examination confirmed metastatic adenocarcinoma. OUTCOMES The patient was followed up for 3 months after surgery, there was no abdominal metastasis or recurrence. CONCLUSION The splenic metastasis from rectal carcinoma 5 years after surgery is rare. If it is a solitary splenic metastasis, splenectomy can effectively improve the prognosis of patients. We review the literature and report this case.

VIVA1: a more invasive subclone of MDA-MB-134VI invasive lobular carcinoma cells with increased metastatic potential in xenograft models. Br J Cancer 2022; 127:56-68. [PMID: 35318435 PMCID: PMC9276762 DOI: 10.1038/s41416-022-01778-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Revised: 01/28/2022] [Accepted: 02/25/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Invasive lobular carcinoma (ILC) is the second most common type of breast cancer. As few tools exist to study ILC metastasis, we isolated ILC cells with increased invasive properties to establish a spontaneously metastasising xenograft model. METHODS MDA-MB-134VI ILC cells were placed in transwells for 7 days. Migrated cells were isolated and expanded to create the VIVA1 cell line. VIVA1 cells were compared to parental MDA-MB-134VI cells in vitro for ILC marker expression and relative proliferative and invasive ability. An intraductally injected orthotopic xenograft model was used to assess primary and metastatic tumour growth in vivo. RESULTS Similar to MDA-MB-134VI, VIVA1 cells retained expression of oestrogen receptor (ER) and lacked expression of E-cadherin, however showed increased invasion in vitro. Following intraductal injection, VIVA1 and MDA-MB-134VI cells had similar primary tumour growth and survival kinetics. However, macrometastases were apparent in 7/10 VIVA1-injected animals. Cells from a primary orthotopic tumour (VIVA-LIG43) were isolated and showed similar proliferative rates but were also more invasive than parental cells. Upon re-injection intraductally, VIVA-LIG43 cells had more rapid tumour growth with similar metastatic incidence and location. CONCLUSIONS We generated a new orthotopic spontaneously metastasising xenograft model for ER+ ILC amenable for the study of ILC metastasis.

[PMID: 32874988 PMCID: PMC7441267 DOI: 10.12998/wjcc.v8.i15.3320] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 05/27/2020] [Accepted: 07/14/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Isolated splenic metastasis is a rare clinical entity. Multiple metastases in the spleen after radical colon resection in a patient who subsequently underwent a second local resection for isolated metachronous splenic metastasis are exceedingly rare.
CASE SUMMARY We report a colon cancer patient who underwent laparoscopic radical colon resection 14 mo previously, and subsequently underwent a second local resection due to local recurrence detected by elevated serum carcinoembryonic antigen (CEA) and positron emission tomography (PET). However, multiple metastases in the spleen were found 7 mo later by elevated serum CEA and PET-magnetic resonance imaging. Then the patient underwent total laparoscopic splenectomy. Local tumor recurrence and splenic metastasis from colorectal cancer (CRC) were found by postoperative pathology. Genetic analysis of these recurrent and metastatic tissues showed KRAS exon2, APC exon16 and TP53 exon6 missense mutations, but no mutations of NRAS, KRAF, EGFR, ERBB2, MET, MLH1, MSH2 and MSH6 were detected. Chemotherapy and target therapy were administered after multiple disciplinary team (MDT) consultation, and no tumor recurrence has been observed to date. We also reviewed the literature by conducting a search of the PubMed database using the following key words: CRC, splenic metastasis, isolated, and review. We identified 34 relevant papers, which included 28 cases of metachronous metastasis and 6 cases of simultaneous metastasis.
CONCLUSION Close monitoring of serum CEA levels is crucial for the detection of isolated splenic metastases after colon surgery. In terms of overall survival and progression-free survival, MDT plays an important role in the entire process of disease management.

Breast cancer cells promote CD169 + macrophage-associated immunosuppression through JAK2-mediated PD-L1 upregulation on macrophages. Int Immunopharmacol 2019; 78:106012. [PMID: 31865052 DOI: 10.1016/j.intimp.2019.106012] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 09/27/2019] [Accepted: 10/27/2019] [Indexed: 01/10/2023]
Abstract
Macrophages are recognized as one of the major cell types in tumor microenvironment, and macrophage infiltration has been predominantly associated with poor prognosis among patients with breast cancer. Using the murine models of triple-negative breast cancer in CD169-DTR mice, we found that CD169+ macrophages support tumor growth and metastasis. CD169+ macrophage depletion resulted in increased accumulation of CD8+ T cells within tumor, and produced significant expansion of CD8+ T cells in circulation and spleen. In addition, we observed that CD169+ macrophage depletion alleviated tumor-induced splenomegaly in mice, but had no improvement in bone loss and repression of bone marrow erythropoiesis in tumor-bearing mice. Cancer cells and tumor associated macrophages exploit the upregulation of the immunosuppressive protein PD-L1 to subvert T cell-mediated immune surveillance. Within the tumor microenvironment, our understanding of the regulation of PD-L1 protein expression is limited. We showed that there was a 5-fold higher relative expression of PD-L1 on macrophages as compared with 4T1 tumor cells; coculture of macrophages with 4T1 cells augmented PD-L1 levels on macrophages, but did not upregulate the expression of PD-L1 on 4T1 cells. JAK2/STAT3 signaling pathway was activated in macrophages after coculture, and we further identified the JAK2 as a critical regulator of PD-L1 expression in macrophages during coculture with 4T1 cells. Collectively, our data reveal that breast cancer cells and CD169+ macrophages exhibit bidirectional interactions that play a critical role in tumor progression, and inhibition of JAK2 signaling pathway in CD169+ macrophages may be potential strategy to block tumor microenvironment-derived immune escape.
