Multiple Myeloma Mimics Bone Metastasis From a Rectal Adenocarcinoma: Im-Kyung Kim, Jeonghyun Kang, Yu Ri Kim, Tae Joo Jeon, Seung Hyuk Baik, Seung-Kook Sohn; Ann Coloproctol. 2017;33(2):70-73. Published online April 28, 2017; DOI: https://doi.org/10.3393/ac.2017.33.2.70

A presumptive diagnosis of bone metastasis can be easily made when a patient with a history of colorectal cancer develops bone lesions that are seen on follow-up imaging. In this case report, we describe a patient whose multiple bone lesions were wrongly attributed to a recurrence of rectal cancer rather than being identified as multiple myeloma lesions. When clinicians detect new, abnormal, bony lesions in a patient with a previous history of cancer, they should consider diseases such as multiple myeloma in their differential diagnosis.

Abstract PDF

The case of a 23-year-old female treated with aggressive high-dose therapy for Burkitt's lymphoma is reported. A positron emission tomography and computed tomography scan after completion of chemotherapy revealed a residual hypermetabolic lesion in the right pelvic cavity. A pelvic magnetic resonance imaging scan showed circumferential wall thickening at the tip of the appendix. A laparoscopic exploration and appendectomy were performed, and a pathologic examination of the resected appendix revealed xanthogranulomatous appendicitis. This is a rare case of a xanthogranulomatous appendicitis mimicking remnant Burkitt's lymphoma after completion of chemotherapy.

Abstract PDF

Purpose

Compared to the stapling technique, the fold-over technique (FO) has the benefit of avoiding the sacrifice of the bowel segment. The aim of this study was to compare short-term outcomes between the FO and a conventional resection.

Methods

Between June 2008 and March 2012, a total of 242 patients who underwent a diverting ileostomy reversal after rectal cancer surgery were selected. Among them, 29 patients underwent the FO. Using propensity scores to adjust for body mass index, previous abdominal surgery history, rectal cancer surgery type (open vs. minimally invasive), and reason for ileostomy (protective aim vs. leakage management), we created a well-balanced cohort by matching each patient who underwent the FO, as the study group, with two patients who underwent a stapled or a hand-sewn technique with bowel resection (RE), as the control group (FO : RE = 1 : 2). Morbidity and perioperative recovery were compared between the two groups.

Results

Twenty-four and forty-eight patients were allocated to the FO and the RE groups, respectively. The mean operation time was 91 ± 26 minutes in the FO group and 97 ± 34 minutes in the RE group (P = 0.494). The overall morbidity rates were not different between the two groups (12.5% in FO vs. 14.6% in RE, P = 1.000). The rate of postoperative ileus was similar between the two groups (8.3% in FO vs. 12.5% in RE, P = 0.710). Although time to resumption of soft diet was shorter in the FO group than in the RE group, the lengths of hospital stay were not different.

Conclusion

The FO and the conventional resection have similar short-term clinical outcomes for diverting ileostomy reversal.

Abstract PDF

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. These tumors tend to present most frequently in the stomach, followed by the small intestine. GISTs can also arise from the omentum, retroperitoneum, mesentery, or pleura and are termed extragastrointestinal stromal tumors (EGISTs) when they do so. EGISTs arising from the omentum are very rare. Due to the limited incidence of EGISTs in the omentum, the diagnostic criteria are not well established, and making a correct diagnosis may be difficult. In this report, we present a case of an EGIST of the omentum with peritoneal metastasis that was initially suspected to be an appendiceal mucinous carcinoma with carcinomatosis on positron emission tomography/computed tomography imaging.

Background

We investigated the prognostic significance of tumor regression grade (TRG) after preoperative chemoradiation therapy (preop-CRT) for locally advanced rectal cancer especially in the patients without lymph node metastasis.

Methods

One-hundred seventy-eight patients who had cT3/4 tumors were given 5,040 cGy preoperative radiation with 5-fluorouracil/leucovorin chemotherapy. A total mesorectal excision was performed 4-6 weeks after preop-CRT. TRG was defined as follows: grade 1 as no cancer cells remaining; grade 2 as cancer cells outgrown by fibrosis; grade 3 as a minimal presence or absence of regression. The prognostic significance of TRG in comparison with histopathologic staging was analyzed.

Results

Seventeen patients (9.6%) showed TRG1. TRG was found to be significantly associated with cancer-specific survival (CSS; P = 0.001) and local recurrence (P = 0.039) in the univariate study, but not in the multivariate analysis. The ypN stage was the strongest prognostic factor in the multivariate analysis. Subgroup analysis revealed TRG to be an independent prognostic factor for the CSS of ypN0 patients (P = 0.031). TRG had a stronger impact on the CSS of ypN (-) patients (P = 0.002) than on that of ypN (+) patients (P = 0.521). In ypT2N0 and ypT3N0, CSS was better for TRG2 than for TRG3 (P = 0.041, P = 0.048), and in ypN (-) and TRG2 tumors, CSS was better for ypT1-2 than for ypT3-4 (P = 0.034).

Conclusion

TRG was found to be the strongest prognostic factor in patients without lymph node metastasis (ypN0), and different survival was observed according to TRG among patients with a specific histopathologic stage. Thus, TRG may provide an accurate prediction of prognosis and may be used for f tailoring treatment for patients without lymph node metastasis.
