Metastatic lung tumor from uterine leiomyosarcoma

We herein present 2 cases of metastatic lung tumor derived from uterine leiomyosarcoma. In the case 1, a 59-year-old woman was admitted to our hospital to examine abnormal shadow detected on chest X-ray. She had undergone hysterectomy and oophorectomy for uterine leiomyosarcoma 19 months previously. A round 3 cm mass in the right lung (S10) was seen on chest X-ray and computed tomography (CT). No other distant metastases or local recurrence were found, and the right lower lobectomy was perfomed under the clinical diagnosis of metastatic lung tumor. Postoperative pathologic examination revealed the tumor as a metastatic leiomyosarcoma. The patient recovered uneventfully, and there have been no signs of recurrence for 26 months after the pulmonary resection. In the case 2, a 58-year-old woman, who had undergone hysterectomy and oophorectomy for uterine leiomyosarcoma 7 months previously, was admitted to our hospital for further examination of pulmonary tumors on chest X-ray. Two tumors were recognized in the left lung (S8 and S10) on chest X-ray and CT. No other distant metastases or local recurrence were found, and the left lower lobectomy was performed under the clinical diagnosis of metastatic lung tumors. Pathological examinations revealed smooth muscle cells with nuclear pleomorphism and high mitotic indices. The tumors proved to be lung metastases derived from uterine leiomyosarcoma. Postoperative course was uneventful. However, brain metastasis was found 1 month after the pulmonary resection, and she underwent resection of brain metastasis. Two months after the brain metastasectomy, local recurrence of the brain tumor developed and re-resection followed by stereotactic radiotherapy was performed. Furthermore, intrapelvic recurrence was found 4 months after the pulmonary resection. Exploratory laparotomy revealed the tumor was unresectable, and she received 4 courses of chemotherapy (paclitaxel and carboplatin). For metastatic lung tumor from uterine leiomyosarcoma, surgery has been considered the best choice. However, for patients with uterine leiomyosarcoma who cannot be treated surgically because of multiple metastatic tumors or poor surgical risk chemotherapy (paclitaxel and carboplatin) or stereotactic radiotherapy can be strategies.     

Pulmonary metastasis of uterine leiomyosarcoma 8 years after hysterectomy; report of a case

A 57-year-old woman, who had undergone hysterectomy for uterine leiomyosarcoma 8 years ago, was admitted to our hospital for pulmonary tumors on chest X-ray. Two tumors were recognized on each side at left and right lung field by computed tomography (CT). Two-staged tumor resection was performed by left thoracotomy and by video-assisted thoracoscopic surgery (VATS) in the right. The histologic findings showed that those tumors were metastases of uterine leiomyosarcoma. This case suggests that the long term follow-up is necessary in the case of uterine leiomyosarcoma after operation.     

Metastatic lung tumor from uterine leiomyosarcoma; report of a case

Endometrial leimyosarcoma is rare neoplasm of all the uterine malignancies. We herein present a case of metastatic pulmonary tumor derived from endometrial leiomyosarcoma She had undergone hysterectomy for leiomyosarcoma. About 10 years after the hysterectomy, metastatic hepatic tumors and peritoneal dissemination were pointed out. Following chemotherapy of cisplatin, ifomide and pirarubicine, right hepatectomy was performed. About 12 years after the hysterectomy, a metastatic lesion appeared in the right lower lung field and right S6 segmentectomy was performed. About 15 months after the pulmonary resection, another metastatic lesion appeared in the remaining right lower lobe. The mass grew so rapidly with involvement to adjacent organs that pericardial resection was necessary with completion right lower lobectomy. Postoperative chemotherapy was performed with the same regimen as previously performed. About 10 months after the second pulmonary resection, she died due to dissemination in the right haemithorax and malignant pericardial effusion. Careful follow up after the surgery for the uterine leiomyosarcoma is recommended because metastatic leiomyosarcoma possibly appears even after a long interval, and its progress can be so intensive that adjuvant chemotherapy is necessary if it can not be treated surgically alone.     

Liver Resections for Metastases from Intraabdominal Leiomyosarcoma

This paper discusses liver resection for intraabdominal leiomyosarcoma metastases as a therapy for carefully selected patients. Of the 83 hepatectomies performed from 1992 to 1996, five were resections for liver metastases due to intraabdominal leiomyosarcoma, in 3 patients. The surgical indication was single liver metastases, without any evidence of extrahepatic disease. No mortality occurred during surgery and the longest survival was 38 months. We concluded that liver resection for leiomyosarcoma metastases can be performed, allowing a long term survival in an occasional patient.     

Leiomyosarcoma and transitional cell carcinoma in the urinary bladder: a case report

A 74-year-old man was admitted for asymptomatic macroscopic hematuria. He had undergone transurethral resection of bladder tumor (TURBT) due to transitional cell carcinoma 30 years ago. Pelvic CT showed two invasive bladder tumors. A 5 cm tumor was on the dome and a 1 cm tumor was on the left lateral wall. TURBT was performed. Pathological examination revealed that they were leiomyosarcoma and transitional cell carcinoma. Radical cystectomy plus bilateral cutaneousureterostomy was performed. He died of lung metastases and local recurrence after 6 months.     

Hepatic metastases from leiomyosarcoma: A single-center experience with 34 liver resections during a 15-year period

OBJECTIVE: To describe a large single-center experience with hepatic resection for metastatic leiomyosarcoma. SUMMARY BACKGROUND DATA: Liver resection is the treatment of choice for hepatic metastases from colorectal carcinoma. In contrast, the role of liver resection for hepatic metastases from leiomyosarcoma has not been defined. METHODS: The records of 26 patients who between 1982 and 1996 underwent a total of 34 liver resections for hepatic metastases from leiomyosarcoma were reviewed. There were 23 first, 9 second, and 2 third liver resections. The records were analyzed with regard to survival and predictive factors. RESULTS: In the 23 first liver resections, there were 15 R0, 3 R1, and 5 R2 resections. Median survival was 32 months after R0 resection and 20.5 months after R1/2 resection. The 5-year survival rate was 13% for all patients and 20% after R0 resection. In 10 patients with extrahepatic tumor at the time of the first liver resection, 6 R0 and 4 R2 resections were achieved. After R0 resection, the median survival was 40 months (range 5-84 months), with a 5-year survival rate of 33%. After repeat liver resection, the median survival was 31 months (range 5-51 months); after R0 resection, median survival was 31 months and after R1/2 resection it was 28 months. There was no 5-year survivor in the overall group after repeat liver resection. CONCLUSIONS: Despite frequent tumor recurrence, the long-term outcome after liver resection for hepatic metastases from leiomyosarcoma is superior to that after chemotherapy and chemoembolization. Although survival after tumor debulking also seems to be more favorable than after nonoperative therapy, these data indicate that only an R0 resection offers the chance of long-term survival. The presence of extrahepatic tumor should not be considered a contraindication to liver resection if complete removal of all tumorous masses appears possible. In selected cases of intrahepatic tumor recurrence, even repeated liver resection might be worthwhile. In view of the poor results of chemoembolization and chemotherapy in hepatic metastases from leiomyosarcoma, liver resection should be attempted whenever possible.     

Two cases of pulmonary leiomyosarcoma

Pulmonary sarcoma is a rare tumor of the lung. There are 81 cases in the literature for review, including our two cases. Our first case who was a thirty-seven year old male who was admitted to our hospital with complaints of left back pain. His chest X-ray showed an 11 X 14 cm tumor shadow in the lower left lung area. A left upper lobectomy was performed, and the histological diagnosis was leiomyosarcoma of the pulmonary vein. He died due to mediastinal recurrence 29 months later. Our other case was a fifty-six year old female. Her chest X-ray showed an abnormal shadow that was a tumor shadow in the right central lung area of 4 cm in diameter. As the diagnosis of the transcutaneous lung biopsy was benign tumor, partial resection of lung was performed. The histological diagnosis was leiomyosarcoma of the bronchus, and she is alive and well at 29 months after the operation. As the rate of diagnosis in leiomyosarcoma detected by transcutaneous lung biopsy is low, the most acceptable method of diagnosis is a total examination, including cytology of sputum, bronchoscopic findings, and roentgenoscopy. Probe thoracotomy would also be necessary if malignancy could not ruled out. The treatment of lobectomy should include lymph node resection.     

Successful Combination Therapy of Radical Liver Resection With 5-Fluorouracil/leucovorin,Oxaliplatin, Plus Bevacizumab for Ascending Colon Cancer With Pulmonary and 43 Liver Metastases: Report of a Case

At the time of diagnosis, 20% to 25% of patients with colorectal cancer already have liver metastases, the presence of which is a most important prognostic factor. A 64-year-old man was admitted to our hospital for investigation of anemia and multiple liver tumors. Examinations revealed ascending colon carcinoma with more than 40 liver metastases and 2 lung metastases. We performed right hemicolectomy with lymph node dissection, which was followed by 5-fluorouracil/leucovorin, oxaliplatin, plus bevacizumab (FOLFOX-BV). After 4 courses of chemotherapy, the lung metastases were in complete remission and the liver metastases had shrunk. We suggested the option of radical liver resection, but the patient declined initially as he had not suffered any severe side effects of FOLFOX-BV. After 23 courses of the chemotherapy, he agreed to undergo hepatectomy. We performed extended right lobectomy with partial left and caudal lobe resection. All of the macroscopic metastatic lesions were resected. Histopathologically, viable cancer cells were recognized in 7 of the 43 liver metastatic lesions. Postoperatively, FOLFOX-BV was restarted and continued for 10 months. At the time of writing, 15 months after the hepatectomy, the patient was well without evidence of recurrence of the cancer.     

Patterns of failure after surgical cure of large liver tumors: A change in the proximate cause of death and a need for effective systemic adjuvant therapy

During a period of 7 years, we have aggressively treated liver tumors whether primary or metastatic. Our experience after 43 curative major liver resections has shown an excellent overall survival: 34 of 43 patients still alive a median of 12 months after liver resection (patient ages ranged from 21 to 85 years, median 57 years). Nineteen patients underwent right hepatic lobectomy, 9 trisegmentectomy, 5 left hepatic lobectomy, 5 extended left hepatic lobectomy, 4 right lobectomy plus left lobe wedge resection, and 1 patient underwent a major hilar wedge resection. Two patients died from sepsis and hepatic failure on or before the 60th postoperative day. One patient with no evidence of recurrent colorectal cancer was lost to follow-up after 2.5 years. One patient died without cancer 12 months after left hepatic lobectomy for colon cancer metastases. Cumulative survival for the entire series and for patients after resection of colorectal cancer metastases was the same: 1 year survival 90 percent; 2 year survival 75 percent, and 3 year survival 65 percent. Seventeen of 30 patients remain disease-free after resection of liver metastases. Of the 13 who had recurrence, 8 are still alive. Ten recurrences were outside of the residual liver (predominantly multiple pulmonary metastases). One recurrence was in the right hemidiaphragm, and only three were in the residual or regenerated liver. Serial carcinoembryonic antigen analysis was the best indicator of recurrence in these 13 patients, 12 of whom were asymptomatic. These data confirm that major liver resection can be performed with minimum postoperative mortality (4.7 percent in this series). More importantly, the majority of patients were cured of their liver metastases. The next goal should be the initiation of adjuvant systemic therapy trials after liver resection in such patients.     

Rupture of liver metastasis of malignant melanoma —A case of hepatic resection—

A case is reported in which resection of the left lateral segment of the liver was performed for rupture of a metastatic malignant melanoma in an attempt to control hemorrhaging. The primary lesion was located in the skin of the head, and there were multiple metastases to the lung, liver and distant nodes. The patient, a 47-year-old woman, had been undergoing systemic chemotherapy for the disseminated disease, but she presented with intraabdominal bleeding from a metastatic nodule in the left lateral segment of the liver. An emergency operation was performed, and the immediate postoperative course was uneventful. She was discharged 10 days after the operation. The patient died, however, of hemorrhagic shock due to renewed intraabdominal bleeding on the 39th postoperative day. It is concluded from the above case that hepatic resection for a bleeding metastasis of malignant melanoma is a viable option even in patients with disseminated disease.

A case of port-site recurrence after laparoscopic adrenalectomy for solitary adrenal metastasis

The case of a patient with bilateral adrenal metastases from lung cancer is described. A left open adrenalectomy at the time of the lung resection had a long-term curative effect. Several months later a right laparoscopic adrenalectomy was performed, but 2 months later a loco-regional recurrence with a port-site metastasis was diagnosed on the right side. Open adrenalectomy, by avoiding the potential for port-site metastasis, may be oncologically superior to laparoscopic adrenalectomy in this situation.     

Long-term survival after a surgical resection of pulmonary metastases from gastric cancer: Report of a case

We describe a patient who survived for a prolonged period after repeated resections of pulmonary metastases from gastric cancer. A 59-year-old man underwent a distal gastrectomy for gastric cancer. A right middle lobectomy and a left lower lobectomy were performed for metastases from gastric cancer at 34 months and 82 months after the initial gastric resection, respectively. The patient died of cerebral infarction 65 months after the first lung resection, with no further relapse. To our knowledge, long-term survival after resection of pulmonary metastases from gastric cancer has only been reported in 3 patients previously. We herein review the literature and discuss the role of surgery in such patients.     

Prolonged survival after repeat resection of pulmonary metastasis from hepatocellular carcinoma

We report a patient in whom two pulmonary resections were performed for lung metastasis after hepatic resection of hepatocellular carcinoma (HCC). A 56-year-old Japanese man with an 8-year history of chronic liver disease was admitted with elevated serum alpha-fetoprotein (AFP) and a liver tumor that had been detected by ultrasonography. Computed tomography showed a 6-cm tumor in the medial segment of the liver, and partial resection of the medial segment was performed. Thirty-six months after the first operation, pulmonary resection was performed for a solitary metastasis in the left lung. Fifty-one months after the second operation, a solitary metastatic tumor was detected in the right lung, without any evidence of recurrence or other metastatic foci, and thoracoscopic partial resection of the right lung was performed as the third operation. The patient is alive 36 months after the second pulmonary resection, has a normal AFP value, and shows no signs of recurrent or metastatic foci. Repeat pulmonary resection for metastasis from HCC resulted in long-term survival in this patient. Received: September 21, 2001 / Accepted: April 2, 2002     

Metachronous common iliac lymph node metastasis after rectosigmoid colon cancer resection: A case report

Introduction and importanceMetastases to common iliac lymph nodes from cancer of the rectosigmoid are extremely rare. We report a patient with a right common iliac lymph node metastasis after rectosigmoid cancer resection.Case presentationThe patient is a 57-year-old woman diagnosed with rectosigmoid cancer (Stage IIIc) who underwent laparoscopic resection followed by 8 courses of adjuvant chemotherapy with capecitabine. Sixteen months after resection, an intra-abdominal mass and a left lung nodule were found on computed tomography scans, which were suspected to be recurrences. Exploratory laparoscopy showed that the abdominal lesion was an enlarged common iliac lymph node, which was completely excised. No other intraabdominal recurrences were found. Subsequently, a left upper lobe lung metastasis was resected thoracoscopically. However, multiple lung metastases developed four months after the lung resection, and systemic therapy was begun.Clinical discussionA lower incidence of lateral lymph node metastases from cancer in the rectosigmoid has been reported. Direct lymphatic pathways from the sigmoid colon or rectosigmoid to lateral lymph nodes have been suspected, which may be associated with the poor prognosis in this patient.ConclusionA metachronous metastasis to a common iliac lymph node from primary rectosigmoid cancer is reported. Common iliac lymph node metastases from rectosigmoid cancer might have more malignant potential, and should be treated in the same manner as peri-aortic lymph node metastases.     

Laparoscopic liver resection for malignant liver tumors: preliminary results of a multicenter European study

OBJECTIVE: To assess the feasibility, safety, and outcome of laparoscopic liver resection for malignant liver tumors. SUMMARY BACKGROUND DATA: The precise role of laparoscopy in resection of liver malignancies (hepatocellular carcinoma [HCC] and liver metastases) remains controversial despite an increasing number of publications reporting laparoscopic resection of benign liver tumors. METHODS: A retrospective study was performed in 11 surgical centers in Europe regarding their experience with laparoscopic resection of liver malignancies. Detailed questionnaires were sent to each surgeon focusing on patient characteristics, clinical data, type and characteristics of the tumor, technical details of the operation, and early and late clinical outcome. All patients had radiologic investigations at follow-up to exclude disease recurrence. RESULTS: From February 1994 to December 2000, 37 patients with malignant liver tumors were included in this study. Ten patients had HCC, including 9 with cirrhotic liver, and 27 patients had liver metastases. The mean tumor size was 3.3 cm, and 89% of the tumors were located in the left lobe or in the anterior segments of the right liver. Liver procedures included 12 wedge resections, 9 segmentectomies, 14 bisegmentectomies (including 13 left lateral segmentectomies), and 2 major hepatectomies. The transfusion rate, the use of pedicular clamping, the conversion rate (13.5% in the whole series), and the complication rate were significantly greater in patients with HCC. There were no deaths. Postoperative complications occurred in eight patients (22%). The surgical margin was less than 1 cm in 30% of the patients. During a mean follow-up of 14 months, the 2-year disease-free survival was 44% for patients with HCC and 53% for patients having hepatic metastases from colorectal cancer. No port-site metastases were observed during follow-up. CONCLUSIONS: In patients with small malignant tumors, located in the left lateral segments or in the anterior segments of the right liver, laparoscopic resection is feasible and safe. The complication rate is low, except in patients with HCC on cirrhotic liver. By using laparoscopic ultrasound, a 1-cm free surgical margin should be routinely obtained. The late outcome needs to be evaluated in expert centers.     

Extended operation for non-small-cell lung cancer invading into the liver.

Direct invasion of a lung cancer into the liver is rare. Here we report a case with a non-small-cell lung cancer invading through the diaphragm into the liver. A 77-year-old woman was admitted to our hospital with a complaint of right chest pain. Chest X-ray showed a 10-cm shadow in the right lower lung field. Chest CT demonstrated a large heterogeneous tumor located in the right lower lobe of the lung. Chest MRI revealed the tumor directly invading through the diaphragm into the liver. Bronchoscopic biopsy revealed squamous cell carcinoma. Surgical resection was performed to prevent intrapulmonary rupture of the necrotic contents. A right lower lobectomy was performed with partial resection of the diaphragm, liver and chest wall. Marlex mesh was used to reconstruct the diaphragm and chest wall. The patient was discharged on the 23rd postoperative day without complications, but died 4 months later from bilateral pulmonary metastases. Invasion to the diaphragm and liver may increase the risk for hematological spread. Although there are limited reports on treatment options, combined resection of the liver should be considered in the case of non-small-cell lung cancer invading the liver, particularly in c-N0M0 case.     

Diaphragmatic metastasis from uterine corpus cancer

We report a case of metastatic diaphragm tumor from uterine corpus cancer. A 72-year-old female had a tumor on right diaphragm 4-years after operation for uterine corpus cancer. After chemotherapy, tumor resection was performed by right lung basal segmentectomy, partial liver resection, and partial diaphragm resection. The pathological examination revealed adenocarcinoma, compatible with uterine corpus cancer, metastasizing in diaphragm and involving lung and liver. After the operation, a local recurrence occurred at parasternal lymph node, which is considered to be present on the efferent route of lymph flow from diaphragm.     

Formal hepatic resection of colorectal liver metastases. Ploidy and prognosis.

Fifty consecutive patients who underwent 52 formal hepatic resections (excluding isolated wedge resections) for metastatic colorectal cancer were analyzed to determine whether DNA content was of prognostic significance. The Dukes' stages of the colorectal primaries were: A (10%), B (20%), C (40%), D (28%), and unknown in 2%. Four patients whose liver metastases were discovered at the time of resection of the primary bowel cancer underwent concomitant liver resection, and the remaining patients underwent delayed resections. The hepatic resections performed were right lobectomy (50%), extended right lobectomy (19%), left lobectomy (13%), left lateral segmentectomy (6%), left lobectomy and right wedge (6%), extended left lobectomy (4%), and right lobectomy and left wedge (2%). The overall morbidity rate was 29%. The in-hospital mortality rate was 9%. As of November 1991, 36 patients have recurred. The 5-year actuarial survival was 28%. Flow cytometry could be performed on 37 archival specimens, 15 of which were found to be diploid whereas 22 were aneuploid. All metastases from Dukes A colorectal primaries demonstrated a diploid DNA content. In addition, there was no difference in actuarial survival between diploid and aneuploid tumors. These data suggest that in selected patients, formal hepatic resection of colorectal liver metastases can be performed with an acceptable morbidity rate, mortality rate, and survival, but ploidy of the resected tumor is not of prognostic significance.     

Präliminare Pfortaderligatur rechts vor erweiterter Hemihepatektomie bei synchronen kolorektalen Lebermetastasen

INTRODUCTION: A two-step procedure is suggested to reduce the overall operative risk in patients with colorectal cancer and large synchronous liver metastases, which demand an extended right hemihepatectomy for R0 resection. METHODS: The clinical course and volumetric evaluation of the liver is described in three patients in whom preliminary ligation of the right branch of the portal vein was performed at the time of colon resection. RESULTS: The size of the left lateral lobes increased by 9.9%, 13.7%, and 4.9% of total liver volume, respectively. At the same time, the noninfiltrated part of the right lobes shrunk by 36.7%, 36%, and 6% ukereas metastatic growth was 26.8%, 22.3%, and 12%. After 7 weeks, extended right hemihepatectomy could be performed in all three patients without signs of hepatic insufficiency, yielding R0 resection. CONCLUSION: Can reduce the risk for extended right hemihepatectomy in selected patients with synchronous colorectal liver metastases.
