Li Q, Mo S, Dai W, Li Y, Xu Y, Li X, Cai G, Cai S. Changes in Incidence and Survival by Decade of Patients With Primary Colorectal Lymphoma: A SEER Analysis. Front Public Health 2020; 8:486401. [PMID: 33178655 PMCID: PMC7596220 DOI: 10.3389/fpubh.2020.486401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Accepted: 09/11/2020] [Indexed: 11/13/2022] Open
Abstract
Purpose: To reveal changes in the incidence, treatment, and survival of patients with colorectal lymphoma. Methods: Patients diagnosed with primary colorectal lymphoma (PCL) or lymphoma between 1973 and 2014 were identified in the SEER registry. The incidence was estimated by age and join-point analysis. The incidence of different subtypes and the surgical resection rates were compared over different time periods. Results: The PCL incidence increased from 1.4 per 1 000 000 people in 1973 to 3.5 in 2014, with an annual percentage change (APC) of 1.98% (95% confidence interval [CI]: 1.29-2.68%, P < 0.001) from 1985 to 2014. No statistically significant change was found between 1973 and 1984. For people younger than 60 years, there was a slight increase in PCL incidence, from 0.6 to 1.4%, from 1973 to 2014. For people age 60 or older, there was a statistically significant increase in PCL incidence from 5.4 to 14.1% over the same time period. The 5-year cause-specific survival (CSS) for PCL improved markedly from 41.6% in the period 1973-1976 to 80.2% in the period 2009-2012 (P < 0.001). Conversely, the proportion of patients who received surgical therapy decreased gradually from 83.3-100 to 47.7-52.6% throughout the studied time period. Conclusions: The incidence of PLC has increased in recent decades. The 5-year CSS of PCL increased continuously, while the rate of surgical resection decreased steadily. These changes in survival trends and therapy strategies indicate that PCL can be well-managed with newer therapeutic reagents.

Primary Colorectal Follicular Lymphoma Observed by Magnifying Endoscopy, with a Five-year Follow-up. Intern Med 2020; 59:1395-1399. [PMID: 32161216 PMCID: PMC7332620 DOI: 10.2169/internalmedicine.3995-19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 01/23/2020] [Indexed: 11/30/2022] Open
Abstract
Colorectal involvement is very rare in cases of follicular lymphoma. Colonoscopy of a 69-year-old man revealed an aggregation of multiple whitish nodules in the sigmoid colon. Magnifying endoscopy with narrow-band imaging demonstrated a coiled and elongated microvascular pattern on the surface and crystal violet staining showed a type I pit pattern. A biopsy showed follicular lymphoma (Grade 1), and no other involvement of lymphoma was detected. Following a diagnosis of primary colorectal follicular lymphoma stage I (Lugano classification), the patient was monitored by watch-and-wait therapy. We documented the endoscopic images of colorectal follicular lymphoma in the present case.
