Isolated metachronous splenic metastasis from synchronous colon cancer

A Glimpse into the Role and Effectiveness of Splenectomy for Isolated Metachronous Spleen Metastasis of Colorectal Cancer Origin: Long-Term Survivals Can Be Achieved

Background: Many papers exploring the role of resectioning metastases in colorectal cancer (CRC) have focused mainly on liver and lung sites, showing improved survival compared with non-resectional therapies. However, data about exceptional metastatic sites such as splenic metastases (SMs) are scarce. This paper aims to assess the role and effectiveness of splenectomy in the case of isolated metachronous SM of CRC origin. Methods: The patients' data were extracted after a comprehensive literature search through public databases for articles reporting patients with splenectomies for isolated metachronous SM of CRC origin. Potential predictors of survival were explored, along with demographic, diagnostic, pathology, and treatment data for each patient. Results: A total of 83 patients with splenectomies for isolated metachronous SM of CRC origin were identified. The primary CRC was at an advanced stage (Duke's C-70.3%) and on the left colon (45.5%) for most patients, while the median interval between CRC resection and SM was 24 months. The median overall survival after splenectomy was 84 months, and patients younger than 62 years presented statistically significantly worse overall survival rates than those ≥62 years old (p = 0.011). There was no significant impact on the long-term outcomes for factors including primary tumor location or adjuvant chemotherapy (p values ≥ 0.070, ns). Laparoscopic splenectomy was increasingly used in the last 20 years from 2002 (33.3% vs. 0%, p < 0.001). Conclusions: Splenectomy is the optimal treatment for patients with isolated metachronous SM of CRC, with the laparoscopic approach being increasingly used and having the potential to become a standard of care. Encouraging long-term survival rates were reported in the context of a multidisciplinary approach. Younger ages are associated with worse survival. Perioperative chemotherapy in the context of a patient diagnosed with SM of CRC origin appears to be a reasonable option, although the present study failed to show any significant impact on long-term survival.

Case report of isolated synchronous multiple splenic metastases from rectal cancer: A case report and brief review of the literature

INTRODUCTION

Isolated splenic metastasis emanating from colorectal cancer is an extremely rare finding, which usually indicates widely disseminated and multiple metastatic cancer. There have only been 39 cases of isolated splenic metastasis reported in the English literature to date.

PATIENT CONCERNS

An 84-year-old female patient presented to our department with dark-red bloody stool that had persisted for 1 month and with an increased serum carcinoembryonic antigen (CEA) level.

DIAGNOSES

A colonoscopy showed a rectal mass located 3 cm from the anal margin, which was 45 mm in diameter. The patient was diagnosed with rectal cancer with splenic metastases by abdomen computed tomography.

INTERVENTIONS

The patient underwent a radical resection of rectal cancer and splenectomy, and the postoperative histopathology confirmed that the splenic lesions were derived from the adenocarcinoma of the rectum.

OUTCOMES

After surgical treatment, the patient recovered well and was recommended for further chemotherapy.

CONCLUSIONS

In addition to revealing a rare case, we also performed a literature review, including a brief discussion about the atypical isolated splenic metastasis from colorectal cancer. Our findings enrich the database of this rare clinical entity and provide experience in the management of splenic metastasis.

Isolated metachronous splenic multiple metastases after colon cancer surgery: A case report and literature review

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.

Sarcoidosis with Multiorgan Involvement and Cutaneous Manifestations after Colonic Adenocarcinoma Resection

Sarcoidosis is a systemic chronic granulomatous disease. It mostly involves the lungs and hilar lymph nodes and produces epithelioid granulomas. Granulomatous (sarcoid) reaction is known to be associated with malignancies; however, it is uncommonly seen with colon carcinomas. Furthermore, systemic sarcoidosis following cancer diagnosis is less commonly seen. To the best of our knowledge, cutaneous sarcoidosis related with an underlying colon carcinoma has not been reported previously in the literature. In this report, we present a very rare case with sarcoidosis development after resection of sigmoid adenocarcinoma, presenting with multiorgan involvement including the skin, eye, joints, and lymph nodes. 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) images showed the skin, lung, spleen, mediastinal, and hilar lymph node involvement. Histopathological examination of skin lesions demonstrated granulomatous dermatitis. This case demonstrates that sarcoidosis can cause intensely FDG-avid lesions on 18F-FDG-PET/CT scans, mimicking metastasis in colon cancer patients. Histopathological evaluation is essential for confirming the diagnosis. 18F-FDG-PET/CT scan provides important information for evaluation of disease extension, progression, and clinical follow-up.

Isolated Metachronous Splenic Metastasis From Colon Cancer Found by 18F-FDG PET/CT

Isolated splenic metastases from solid malignancies are very rare. We report the case of a 58-year-old woman with isolated metachronous splenic metastasis from colon cancer detected 18 months after colectomy. F-FDG PET/CT allowed its recognition and guided the therapeutic approach toward surgery.

Surgical resection of splenic metastasis from the adenosquamous gallbladder carcinoma: A case report

•

We report a case of splenic metastasis of adenosquamous carcinoma of gallbladder.

•

Splenic metastasis of adenosquamous gallbladder carcinoma is a rare.

•

Resection of splenic metastasis may represent the treatment for prolonging survival.

Introduction

Splenic metastasis of gallbladder carcinoma is extremely rare. Specific anatomical, histological, and functional properties of spleen are believed to be responsible for the rarity of solitary splenic metastasis.

Presentation of case

We present the case of a 62-year-old female who developed metachronous splenic metastasis of adenosquamous carcinoma of the gallbladder. We performed central bisegmentectomy of the liver for gallbladder carcinoma. The patient subsequently presented 3 months later with isolated splenic metastasis and liver metastasis. Splenectomy and partial hepatectomy was performed at this time. Histological examination confirmed metastatic adenosquamous carcinoma of the gallbladder. No signs of recurrence were observed at 3 months after the second surgery.

Discussion

Although splenectomy provides a potential means of radical treatment in patients with isolated splenic metastases, it should be performed with caution as splenic metastatic lesions may represent the initial clinical manifestation of systemic metastases at multiple sites. In this case, radical surgery was performed following the confirmation of no new unresectable metastatic lesions or systemic dissemination.

Conclusion

This is the first report on the adenosquamous splenic metastasis from the gallbladder carcinoma. Curative resection may be the treatment of choice for prolonging survival in patients with the splenic metastasis of gallbladder carcinoma.

Solitary Splenic Metastasis from a Mucinous Adenocarcinoma of the Cecum. A Case Report

Reports of cases of splenic metastasis are very rare, even more so when they are derived from a mucinous adenocarcinoma of the cecum. The most common presentation of a solitary splenic metastasis is from lung primary tumors, endometrium, ovary, cervix, stomach, colon, breast, bladder, and skin. We report the case of an 84-year-old woman with a solitary splenic metastasis from a mucinous adenocarcinoma of the cecum. Until this work, only 18 cases of solitary splenic metastases from colorectal carcinomas have been described in the literature.

The Mysterious Organ. Spectrum of Focal Lesions within the Splenic Parenchyma: Cross-Sectional Imaging with Emphasis on Magnetic Resonance Imaging

Incidental splenic lesions are frequently encountered at imaging performed for unrelated causes. Splenic cysts, hemangiomas, and lymphomatous involvement are the most frequently encountered entities. Computed tomography and sonography are commonly used for initial evaluation with magnetic resonance imaging reserved as a useful problem-solving tool for characterizing atypical and uncommon lesions. The value of magnetic resonance imaging lies in classifying these lesions as either benign or malignant by virtue of their signal-intensity characteristics on T1- and T2-weighted imaging and optimal depiction of internal hemorrhage. Dynamic contrast-enhanced sequences may improve the evaluation of focal splenic lesions and allow characterization of cysts, smaller hemangiomas, and hamartomas. Any atypical or unexplained imaging feature related to an incidental splenic lesion requires additional evaluation and/or follow-up. Occasionally, biopsy or splenectomy may be required for definitive assessment given that some of tumours may demonstrate uncertain biologic behavior.

Laparoscopic approach for isolated splenic metastasis: comprehensive literature review and report of 6 cases

BACKGROUND

Splenic metastases are extremely unusual. The aim of this paper is to review the world experience to date concerning to laparoscopic approach for splenic metastasis, and to report ours at the Hospital de Sant Pau.

METHODS

Literature review was carried out and relevant reports on laparoscopic approach to splenic metastasis were obtained. In addition, we reviewed our patient's database and retrieved the data of those who underwent laparoscopic splenectomy due to splenic involvement.

RESULTS

Electronic search yielded 8 relevant articles on open splenectomy and 7 articles on laparoscopic splenectomy for splenic metastasis. During the study period, 6 patients were operated on laparoscopically. Primary neoplasms were 3 melanomas, 2 colon carcinomas, and 1 malignant fibrous histiocytoma. None of the patients had surgical complications. Outcome ranged from 2-month to 11-year survival.

CONCLUSIONS

The laparoscopic approach for splenic metastasis is feasible. Of course, it must be individualized in each case.

Isolated splenic metastasis from colorectal mucinous carcinoma

Metastatic tumors of the spleen are rare and occur in the presence of disseminated visceral metastasis. Isolated splenic metastases from colorectal carcinoma are rare and only 19 cases have been reported in English literature. We report a case of isolated splenic metastasis in a 52-year-old man, occurring 9 years after the primary colorectal mucinous carcinoma was treated by anterior resection. The patient underwent splenectomy along with adjuvant chemotherapy and is alive and asymptomatic at 22 months follow-up.

[Splenic metastasis from colonic adenocarcinoma - about a case and literature review]

L'atteinte métastatique de la rate est rare et exceptionnellement isolée. En effet, elle survient généralement dans le cadre d'une atteinte multi viscérale. Les cancers les plus pourvoyeurs de métastase splénique sont les mélanomes, les carcinomes de l'ovaire, du sein et du poumon. Dans le cancer colique, l'atteinte métastatique isolée de la rate est rare, dix cas seulement ont été décrits dans la littérature jusque-là. À travers cette revue, nous décrivons un nouveau cas présentant un adénocarcinome colique avec métastase splénique métachrone, tout en discutant les aspects cliniques et les différentes approches thérapeutiques décrites dans la littérature. Nous rapportons un nouveau cas d'un patient âgé de 46ans ayant un adénocarcinome colique traité, et qui a présenté 5 ans plus tard une métastase splénique de découverte fortuite lors d'un bilan radiologique de surveillance, pour laquelle le patient a bénéficié d'une splénectomie suivie d'une chimiothérapie systémique avec une bonne évolution. Les métastases spléniques isolées des tumeurs solides sont rares, et leur diagnostic est souvent de découverte fortuite. La splénectomie totale est un moyen efficace de faire le diagnostic définitif de ces métastases et de les traiter afin de prévenir les complications et d'améliorer la survie.

Metastasis to the pancreas and the spleen: an increasing diagnostic and therapeutic challenge

We have reviewed the electronic biopsies database files of the Department of Surgical Pathology, Fundación Jiménez Díaz in Madrid (Spain). In this time period (1998–2010) we have found 3 pancreatic metastasis and 5 splenic metastasis. Two of the pancreatic metastases were originated in clear cell renal cell carcinomas. The last pancreatic metastasis was from a malignant cutaneous melanoma diagnosed and treated 8 years before. As for splenic metastasis, three of them were diagnosed during the abdominal surgery for primary therapy of the tumour (2 ovaries and one endometrium), while the remaining 2 corresponded to metastasis from a lung primary diagnosed 1 year before and a colonic primary diagnosed 6 years before. The patients with splenic metastasis died on the short term with progression of the disease despite resection of the splenic lesions, while the patients with pancreatic metastasis have survived longer.

Clinical and pathological features of splenic metastases of colorectal carcinoma: an analysis of three cases

AIM: To study the clinicopathological features and diagnosis of splenic metastases of colorectal carcinoma.

METHODS: The clinical data for three patients with splenic metastases of colorectal carcinoma were retrospectively analyzed to investigate the clinical features, methods of diagnosis and treatment, and prognosis of the disease.

RESULTS: A definite diagnosis was achieved preoperatively by PET/CT in one patient. Two patients were initially diagnosed with splenic abscess. Splenectomy was performed in two patients, and exploratory laparoscopy in one patient. One patient died 2 wk after operation, and the other two patients survived for 2 and 6 years, respectively.

CONCLUSION: Splenic metastases of colorectal carcinoma are a rare disease that is frequently misdiagnosed. Imaging examination is helpful in diagnosing splenic metastases of colorectal carcinoma. Patients with splenic abscess should be suspected of having concomitant colorectal carcinoma. Long-term survival can be achieved by splenectomy in colorectal carcinoma patients with isolated splenic metastasis.

Isolated splenic metastasis from colorectal cancer

Splenic metastases are unusual, arising in less than 1% of all metastases. Isolated solitary splenic metastasis from colorectal carcinoma is considered exceptional. This rarity has been explained by several hypotheses relating to the anatomical, histological, and immunological features of the spleen. We review the reported cases of isolated solitary splenic metastasis from colorectal carcinoma and discuss the diagnostic and therapeutic options for this entity. We searched the English-language medical literature, using the Medline and Pubmed databases from January 1966 through July 2010, for articles reporting isolated splenic metastasis from colorectal carcinoma. Only 26 cases have been reported; four cases had synchronous splenic metastasis. Fifteen patients had regional lymph node involvement on diagnosis of primary carcinoma. The primary tumor was located in the left colon or in the rectum in 18 cases. Carcinoembryonic antigen (CEA) level was elevated in 73% of cases. All patients underwent curative splenectomy; only one patient had laparoscopic resection of the spleen. Mean reported survival interval was 19.5 months; only three patients were deceased at last follow-up. Solitary splenic metastasis from colorectal carcinoma is very rare; clinicians are advised to pay close attention when routinely evaluating patients with serial CEA levels and abdominal scans. Splenectomy seems to be the preferred treatment modality with improvement of long-term survival. However, definitive conclusions cannot be drawn from the small number of case reports available.

Case of a sigmoid colon cancer with metachronous metastases to the mesorectum and the abdominal wall

Backround

Sigmoid colon cancer metachronous metastases commonly occur in the liver and lungs with sporadic reports also to the spleen, stomach, thyroid gland, abdominal wall and upper urinary tract. This is a rare case of metachronous metastases invading the mesorectum and the abdominal wall.

Case presentation

A 72-year-old female underwent sigmoidectomy for stage I (T2N0 M0) sigmoid colon cancer in May 2008. In June 2009, an abdominal computed tomography scan revealed a tumor 2 cm in size at the lower anterior mesorectum and a second mass 2 cm in size at the anterior abdominal wall midline. Total colonoscopy showed no mucosal lesion. The serum carcinoembryonic antigen level was normal. A biopsy of the mesorectum tumor showed similar histologic characteristics with the primary tumor. Since no other site of recurrence was identified, an abdominoperineal resection was attempted. During the operation and after the removal of the incision recurrence, sinus bradycardia and signs of myocardial ischemia were noticed. A loop transverse colostomy was immediately perfomed and the operation was terminated. Postoperative cardiologic examination revealed an acute myocardium infract. Chemo-radiation of the mesorectum tumor and re-evaluation for surgical excision was decided.

Conclusion

Metachronous metastasis of the mesorectum from sigmoid colon cancer is extremely rare. Although patterns of lymphatic spread from rectal cancer to sigmoid colon have recently been demonstrated, there is no evidence of metachronous mesorectum invasion from sigmoid colon cancer. This could be the issue for future trials.

Metachronous splenic metastasis from colonic carcinoma five years after surgery: a case report and literature review

Metastatic lesions of the spleen are a rare finding and are generally associated with widespread disease. Moreover, solitary metastases of the spleen are exceptional. In this paper, we describe the case of a patient who developed an isolated splenic metastasis from colon carcinoma five years after surgery, and was successfully treated by splenectomy. We also review the scant literature experience discussing clinical diagnosis and approaches to this uncommon event.

Isolated splenic metastases of colorectal carcinoma--case report and review of literature

It is very rare situation when surgeon can virtually expect a curative operation after revealing distal metastases of colorectal carcinoma. In case of isolated splenic metastases, splenectomy can result with good five year survival rate. There are no more than 15 cases of isolated splenic metastases publish in English speaking literature. This article reveals our case along with a literature review and brief discussion of diagnostic and therapeutic options.

Clinical case report and literature review: metachronous colorectal splenic metastases

A 52-year-old woman with a rising carcinoembryonic antigen CEA, no clinical or radiological findings, a negative colonoscopy, and a positron emission tomography (PET) scan that revealed an isolated hypermetabolic lesion in the spleen. The patient underwent splenectomy by laparoscopic surgery. The pathological study confirmed the presence of an isolated metastasis to the spleen. This case reveals the rare occurrence of isolated splenic metastases in the context of colorectal cancer and illustrates the role of PET when a patient shows a rising CEA with negative clinicoradiological studies.

Hepatectomy for colorectal metastases in the presence of extrahepatic disease

This article focuses on hepatectomy for colorectal liver metastases (CLM) in the presence of intra-abdominal extrahepatic disease. The results reported in the literature are reviewed, and the indications and contraindications for hepatectomy in patients who have CLM with extrahepatic disease are discussed in light of the available evidence.

Isolated splenic metastasis from colorectal cancer: report of a case

The authors report a case of a patient with splenic metastasis with previous history of colorectal cancer. A 69-year-old woman underwent a left hemicolectomy for sigmoid colon cancer. The tumor was staged T3N0M0. Two years after the operation, there was an elevation of CEA and computed tomography (CT) scan revealed a mass in the spleen, considered as an isolated metastasis. The patient underwent splenectomy. Histological diagnosis confirmed a metastatic adenocarcinoma from colorectal carcinoma. Patient was alive without neoplasic recurrence 5 years after splenectomy. Generally, splenic metastasis is uncommon. However, with the case of colorectal cancers, metastasis to the spleen is particularly rare. As with splenic metastasis of all primary tumors, the literature recommends that the treatment, where possible, is surgical.

Synchronous isolated splenic metastasis from colon carcinoma and concomitant splenic abscess: A case report and review of the literature

This study aimed to describe a case in which an isolated splenic metastasis was synchronous with the colonic primary and a concomitant splenic abscess was associated. A wide review of the literature was also performed. A 54-year-old woman with abdominal pain and fever was admitted to our department. Abdominal CT revealed two low-density areas in the spleen and wall-thickening of the left colonic flexure, which was indistinguishable from the spleen parenchyma. The patient underwent emergency celiotomy, with the presumptive diagnosis of obstructing colon carcinoma of the splenic flexure, and concomitant splenic abscess. Subtotal colectomy and splenectomy were performed. Pathological findings were consistent with mucinous colonic carcinoma, synchronous isolated splenic metastasis and concomitant splenic abscess. This paper is also a review of the existing literature on the association between colorectal cancer and splenic metastasis. Only 41 cases of isolated splenic metastasis from colon carcinoma have been reported in the literature. This report is the third described case of synchronous isolated splenic metastasis from colon carcinoma. Only one case with concomitant splenic abscess has been previously reported. When obstructing left-sided colorectal cancer is suspected, careful CT examination can allow early diagnosis of splenic involvement by the tumor. The literature review suggests that there might be a significant improvement in survival following splenectomy for a metachronous isolated splenic metastasis from colon carcinoma. Prognosis for synchronous splenic metastasis seems to be related to the advanced stage of the disease. Nevertheless, no definitive conclusions can be drawn because of the small number of cases.
