Ascending Colon Cancer with Hepatic Metastasis and Cholecystolithiasis in a Patient with Situs Inversus Totalis Without Any Expression of UVRAG mRNA: Report of a Case

Situs inversus totalis refers to an inverted position of part or all of the viscera, which represents a mirror-image of the normal location, and it is a relatively rare condition that occurs in one in 4000–8000 people in Japan. We herein report a patient demonstrating a combination of situs inversus totalis, colon cancer with hepatic metastasis, and cholecystolithiasis, who was treated surgically. We found no expression of UVRAG mRNA in our case, thus suggesting that the UVRAG gene is partly responsible for this condition.     

Situs Inversus Totalis with Malignant Lymphoma of the Stomach: Report of a Case

Situs inversus totalis is a rare congenital anomaly that often occurs concomitantly with other disorders. We report a case of situs inversus totalis with malignant lymphoma of the stomach, which was successfully treated by surgery followed by chemotherapy and irradiation. The patient was a 51-year-old woman who present with colicky pain in the left upper quadrant of her abdomen. Chest X-ray showed a right-sided heart, and ultrasonography and computed tomography (CT) of the abdomen showed a situs inversus totalis with multiple gallstones in the gallbladder. Tree-dimensional reconstructed CT of the abdomen showed no other malformations coexisting with situs inversus totalis, but a barium upper gastrointestinal series found an inverted stomach and an elevated tumor with ulceration in the center, localized in the antrum of the stomach. First, we performed a cholecystectomy, followed by a total gastrectomy with dissection of the lymph nodes and splenectomy, and Roux-en-Y reconstruction. Histopathological examination confirmed a diagnosis of malignant lymphoma of the stomach (diffuse large B-cell type) with metastasis to the regional lymph nodes. Chemotherapy using the CHOP regimen was given three times, starting 1 month postoperatively. A follow-up CT scan showed enlargement of one lymph node around the abdominal aorta and irradiation was delivered to the area of the inverted Y in the abdomen. At the time of writing, 10 months after surgery, the patient is well with no signs of recurrence and leading a normal life. Careful preoperative assessment is very important for determining the most appropriate surgical procedure in patients with situs inversus totalis associated with a malignancy.

Situs Inversus Totalis (SIT) with Hepatocellular Carcinoma (HCC): A Rare Case Report and Review of 12 Other Cases

Hepatocellular carcinoma (HCC) is the seventh-most common malignancy in males and ninth in females with incidence of one million new cases every year. Situs inversus totalis (SIT) is a rare congenital condition, in which there is a mirror-image transposition of both the abdominal and thoracic viscera. There are very few reported cases of HCC developing in people with SIT. In this review, we present a new case of HCC with SIT, and a review of literatures published between 1983 and 2011 on it. The literatures in English were searched through PubMed and Google Scholar, while those in Japanese language were accessed through J-EAST and translated in English with the help of Google translator on 22 April 2012. There are 6 English and 6 Japanese literatures showing 12 published cases, of which 10 cases were from Japan, 1 from Taiwan and 1 from China. Our case is probably the first case in the world beyond these regions. The articles containing adequate information, such as patient age and sex, investigations, diagnosis, type of congenital anomalies and methods of surgery, were reviewed. On reviewing the literature, we observed that clinical manifestations, laboratory findings and etiology correlate well with HCC, while anomalous hepatic vascularity correlates well with SIT. The reason for high incidence of HCC with SIT in Japan is not well correlated, but may be explained by higher incidence of SIT. All varieties of hepatic resection were feasible in cases of SIT.     

Laparoscopic Adjustable Gastric Banding for Morbid Obesity in a Patient with Situs Inversus Totalis

Laparoscopic surgery with situs inversus may pose particular challenges to the surgeon. We discuss a case of undiagnosed situs inversus totalis in a morbidly obese patient undergoing laparoscopic adjustable gastric banding (LAGB). The patient was a 29-year-old male with a body mass index (BMI) of 56. There was no prior knowledge of his situs inversus totalis, which was only discovered during laparoscopy at the time of surgery. The operative challenges are discussed. LAGB was performed successfully without complication. Postoperative imaging confirmed dextrocardia and situs inversus totalis, as well as correct gastric band position. However, there has been subsequent gastric band erosion and eventual band removal. We discuss the appropriateness of LAGB in this group of patients.     

Retroversus Implantation of a Liver Graft: A Novel Approach to the Deceased Donor with Situs Inversus Totalis

Situs inversus totalis is a rare anatomical abnormality that results in dextrocardia, mirror image of normal abdominal organs and other congenital abnormalities. Deceased donors with this condition are often declined on anatomic concerns. While there have been numerous reports of successful liver transplantation in recipients with situs inversus, review of the world's literature provided only three case reports using deceased donors with situs inversus. In this report, a novel approach to implantation of a liver graft from a donor with situs inversus is presented. To avoid possible torsion and blockage of venous outflow, a modified retroversus piggyback technique with 180 degrees ventral caudal (backwards) rotation of the liver graft along the axis of the vena cava was performed. This orientation resulted in the retro hepatic vena cava facing anteriorly and the larger anatomic liver lobe in the right upper quadrant. Excellent outcome was achieved without technical difficulty. Retroversus implantation of a liver graft from a donor with situs inversus is safe and effective and associated with favorable outcome.     

Single-Incision Laparoscopic Surgery for Colon Cancer in Patient with Situs Inversus Totalis: Report of a Case

A preliminary experience with single-incision laparoscopic colectomy for colon cancer with situs inversus totalis (SIT) is reported. An 87-year-old man was admitted because of a fecal occult blood. A colonoscopy revealed cecal cancer. An air-barium and a computed tomography contrast enema showed the right-sided descending colon and the left-sided ascending colon and cecum. The surgical procedures were as follows: First, a Lap protector was inserted through a 2.5-cm transumbilical incision. Three 5-mm ports were placed in the Lap protector. We successfully performed ileocolectomy with lymph node dissection by using a single-incision laparoscopic approach without any technical problems. The operative time was 125 min, and blood loss was negligible. Postoperative follow-up did not reveal any umbilical wound complications and recurrences.     

Esophagectomy via left thoracotomy for esophageal cancer with situs inversus totalis: Report of a case

We report a case of successful esophagectomy via a left thoracotomy for esophageal cancer in a 57-year-old Japanese man with situs inversus totalis. An upper gastrointestinal endoscopy, performed to investigate the cause of dysphagia, revealed a 7-cm irregular shaped mass occupying more than half of the circumference of the middle-third of the esophagus. Computed tomography (CT) showed enlarged mediastinal lymph nodes and situs inversus totalis. Histological examination of a biopsy specimen revealed squamous cell carcinoma of the esophagus. Although esophagectomy is usually performed through a right thoracotomy because of the left position of the aortic arch, we performed successful subtotal esophagectomy with radical lymph node dissection through a left thoracotomy. During surgery, we modifi ed the standard surgical technique in a mirrorimage fashion to complete the esophagectomy safely. The patient had an uneventful postoperative course.     

Situs Ambiguous with Gastric Cancer: Report of a Case

Situs ambiguous is an unpredictable anomaly characterized by disorder of the organ arrangement in the chest and abdomen. We report a case of situs ambiguous found incidentally in a 73-year-old man with gastric cancer. Preoperative imaging showed polysplenia, a bridging liver, a midline gall bladder, and pancreatic divisum. The vessels around the stomach were clearly shown by computed tomography with multiplanar reconstruction (MPR). Computed tomography with MPR proved a good diagnostic tool for identifying both the abdominal vessels and the location of the organs. Based on a precise evaluation of this unusual anatomy, we performed distal gastrectomy with dissection of the regional lymph nodes.     

Pseudo-Meigs' Syndrome Caused by Ovarian Metastasis from Colon Cancer: Report of a Case

We report an extremely rare case of pseudo-Meigs' syndrome caused by ovarian metastases from colon cancer, and review the literature on this unusual entity. A 41-year-old woman was admitted for investigation of abdominal fullness and dyspnea. Preoperative examinations revealed a huge pelvic tumor, adenocarcinoma of the sigmoid colon, marked ascites, and bilateral pleural effusion. Laparotomy confirmed that the huge mass was comprised of bilateral ovarian tumors. Resection of the sigmoid colon and bilateral oophorectomies were performed. Although short-term intrathoracic drainage was required, the hydrothorax and ascites rapidly resolved in the postoperative period. The patient died of disseminated liver and bone metastases 8 months after her operation; however, ascites and hydrothorax were not clinically noted until death. This and five other reported cases demonstrate that ovarian metastasis from colorectal cancer may occasionally cause pseudo-Meigs' syndrome, and that resection of the ovarian lesions could improve the prognosis.

Successful Treatment of Recurrent Liver Metastases from Gastric Cancer by Repeated Hepatic Resections: Report of a Case

We describe herein the case of a patient in whom recurrent liver metastases from gastric cancer were successfully treated by performing repeated hepatic resections. A 63-year-old man underwent a total gastrectomy with regional lymph node dissection for an advanced gastric cancer on November 17, 1992, the pathological findings of which confirmed a diagnosis of well-differentiated tubular adenocarcinoma, ss, INFα, ly1, v0, n1(+). Follow-up computer tomography (CT) and ultrasonography scans done 7 months after the gastrectomy revealed a metastasis in the liver S5, and a partial resection of S5 was performed on July 5, 1993. Subsequently, on November 17, 1994, an anterior segmentectomy of the liver was performed for a liver metastasis in the liver S8, then on August 11, 1998, a partial resection of the liver S6 was performed for a metastasis in the liver S6. The pathological findings of each liver specimen resected were compatible with metastatic adenocarcinoma from the primary gastric cancer. The liver tumors were expansive-growing tumors with capsules and massive necrosis. The patient is currently well with no evidence of recurrence on repeat CT scans, 6 years 6 months since-the initial gastrectomy, and 5 years 10 months since the first hepatic resection.

Long-Term Survival Following Treatment with Antineoplastons for Colon Cancer with Unresectable Multiple Liver Metastases: Report of a Case

We report a case of survival for nearly 8 years after treatment of unresectable multiple liver metastases from colon cancer, using microwave ablation and the nontoxic antitumor agent, the antineoplastons. A 72-year-old man diagnosed with adenocarcinoma of the ascending colon and 14 bilateral liver metastases underwent a right hemicolectomy combined with microwave ablation of six metastatic liver tumors. We also decided to give antineoplastons to inhibit metastatic tumor growth and recurrence. Antineoplaston A10 was given intravenously, followed by oral antineoplaston AS2-1. Computed tomography scans done 1 and 4 years after the initial diagnosis showed recurrent tumors in S₄ and S₇, respectively. The patient underwent a second and a third microwave ablation of the recurrent tumors, and has survived for nearly 8 years without suffering any serious adverse effects. He is currently free from cancer. This case report demonstrates the potential effectiveness of the nontoxic antitumor agent, the antineoplastons, for controlling liver metastases from colon cancer.

Manifestation of Bilateral Huge Ovarian Metastases from Colon Cancer Immediately After the Initial Operation: Report of a Case

This report describes the case of a 34-year-old premenopausal woman in whom bilateral huge ovarian metastases were found immediately after initial surgery for sigmoid colon cancer. Both ovaries had been intact at the time of sigmoidectomy, but 2 months later, she complained of persistent vaginal bleeding, and large bilateral metastases were detected in both ovaries. Oophorectomy with intraperitoneal chemotherapy proved ineffective and the patient died 3 months later, after a second operation, from peritoneal dissemination. This case report serves to demonstrate the importance of searching for synchronous or nonsynchronous metastases to the ovaries after surgery for colon cancer in young women. Consideration should also be given to the feasibility of performing prophylactic oophorectomy or administering intensive chemotherapy in association with colon resections for carcinoma for premenopausal women because of the ineffectiveness of these modalities as treatment for metastatic disease.

Complete Response of Highly Advanced Colon Cancer with Multiple Lymph Node Metastases to Irinotecan Combined with UFT: Report of a Case

Massive lymph node metastasis of the para-aortic region and supraclavicular lymph nodes, Virchow's lymph node metastasis due to colon cancer, is extremely rare. We herein report a case of such systemic lymph node metastasis that was successfully treated with a combination of irinotecan (CPT-11) and UFT, a combination drug of tegafur and uracil. The patient was a 57-year-old woman who had a tumor in the ascending colon, and massively swollen para-aortic and supraclavicular lymph node metastasis. She was treated with combination chemotherapy of CPT-11 and UFT. The main tumor was detected as a decompressed scar, and the supraclavicular and para-aortic lymph nodes had completely disappeared after the second cycle of treatment. A histopathological examination and immunohistochemistry with cytokeratin showed complete remission of adenocarcinoma in the tumor and para-aortic lymph nodes. She remains alive without recurrence 52 months after chemotherapy. Combination chemotherapy of CPT-11 and UFT may be of potential value in the treatment of advanced colorectal carcinoma, and both histopathological and immunohistochemical confirmation of a complete remission may indicate prolonged disease-free survival.     

Long-Term Survival Achieved by Resection of Metastases in the Liver and Lung in a Patient with Recurrent Colonic Cancer: Report of a Case

A 58-year-old man who underwent a potentially curative resection of cancer of the sigmoid colon at another hospital was subsequently followed up at our hospital. A lateral segmentectomy was per-formed for a solitary hepatic metastasis, and partial resection of right S1 was later carried out for a pulmonary metastasis. Another pulmonary metastasis was found 6 years after his third operation and to minimize the area to be resected, bronchial arterial infusion chemotherapy was performed twice. A 51% reduction in the size of the tumor was achieved, so a right upper lobectomy and wedge resection of the bronchus were performed. The patient remains alive 14 years after the initial resection of colonic cancer. This case is considered noteworthy because it demonstrates the potential effectiveness of local adjuvant chemotherapy and the possibility of extended survival in a patient who has undergone resection of both hepatic and pulmonary metastases from colonic cancer.

Evaluation of Treatment for Synchronous Hepatic Metastases from Gastric Cancer with Special Reference to Long-Term Survivors

Abstract. Purpose: The purpose of this study was to determine the most effective means of treating liver metastases from gastric cancer. Methods: We retrospectively examined 43 patients with liver metastases, but without peritoneal dissemination, who had received different forms of treatment. Results: The crude 5-year survival rates of patients who underwent gastrectomy with complete hepatectomy (curative gastrectomy), noncurative gastrectomy, and no gastrectomy were 33.3%, 3.7%, and 0%, respectively. The curative gastrectomy group showed the highest survival rate (not significant). The median survival of patients given hepatic artery infusion (HAI), systemic chemotherapy, and no chemotherapy were 353, 189, and 61 days, respectively. The patients given chemotherapy survived significantly longer than those not given chemotherapy. Three patients survived for more than 5 years without any signs of recurrence. The long-term survivors all had primary lesions without serosal invasion (T2) and no other noncurative factors. Two patients underwent curative gastrectomy and one underwent noncurative gastrectomy. All were given postoperative chemotherapy; as HAI in two cases, and as systemic chemotherapy in one case. Conclusion: These findings suggest that curative gastrectomy combined with HAI or systemic chemotherapy should be attempted for patients with primary tumors without serosal invasion or any other noncurative factors.

Long-Term Survival After Repeat Resections of Metastases in Liver, Lung, and Stomach from Sigmoid Colon Cancer: Report of a Case

A 74-year-old female patient underwent a simultaneous colectomy and hepatectomy for sigmoid colon cancer and its hepatic metastases. Six months later she underwent a hepatectomy for recurrent hepatic metastases; then 10 months later, a pulmonary resection for pulmonary metastasis; and 24 months later, a partial gastrectomy for gastric metastasis. As of December 2005, at 7 years 6 months after the first surgery and at 4 years after the last surgery, the patient is still alive with a good quality of life and no sign of recurrence.     

Malignant Pheochromocytoma with Hepatic Metastasis Diagnosed 10 Years After a Resection of the Primary Incidentaloma Adrenal Lesion: Report of a Case

A 40-year-old woman developed hepatic tumors 10 years after a resection of pheochromocytoma of the left adrenal gland. Computed tomography showed a round tumor measuring about 35mm in diameter at segment V of the liver (Couinaud's classification), and magnetic resonance imaging showed another tumor measuring about 5mm at segment V-VIII of the liver. The results of the endoscopic examination of her upper gastrointestinal tract and barium enema were normal. Owing to a suspected hepatic metastasis of malignant pheochromocytoma, a right lobectomy of the liver was performed. Postoperatively, [131I]metaiodobenzylguanidine scintigram and computed tomography showed no other residual tumors nor metastasis. The present case suggests that a long-term follow-up only by endocrinological examinations is insufficient to find newly developed metastatic foci, while routine diagnostic imaging at frequent intervals is necessary in cases of pheochromocytoma.     

The Impact of Primary Tumor Location on Long-Term Survival in Patients Undergoing Hepatic Resection for Metastatic Colon Cancer

Background

The impact of primary tumor location on overall survival (OS), recurrence-free survival (RFS), and long-term outcomes has not been well established in patients undergoing potentially curative resection of colorectal liver metastases (CRLM).

Methods

A single-institution database was queried for initial resections for CRLM 1992–2004. Primary tumor location determined by chart review (right = cecum to transverse; left = splenic flexure to sigmoid). Rectal cancer (distal 16 cm), multiple primaries, and unknown location were excluded. Kaplan–Meier and Cox regression methods were used. Cure was defined as actual 10-year survival with either no recurrence or resected recurrence with at least 3 years of disease-free follow-up.

Results

A total of 907 patients were included with a median follow-up of 11 years; 578 patients (64%) had left-sided and 329 (36%) right-sided primaries. Median OS for patients with a left-sided primary was 5.2 years (95% confidence interval [CI] 4.6–6.0) versus 3.6 years (95% CI 3.2–4.2) for right-sided (p = 0.004). On multivariable analysis, the hazard ratio for right-sided tumors was 1.22 (95% CI 1.02–1.45, p = 0.028) after adjusting for common clinicopathologic factors. Median RFS was marginally different stratified by primary location (1.3 vs. 1.7 years; p = 0.065). On multivariable analysis, location of primary was not significantly associated with RFS (p = 0.105). Observed cure rates were 22% for left-sided and 20% for right-sided tumors.

Conclusions

Among patients undergoing resection of CRLM, left-sided primary tumors were associated with improved median OS. However, long-term survival and recurrence-free survival were not significantly different stratified by primary location. Patients with left-sided primary tumors displayed a prolonged clinical course suggestive of more indolent biology.
