Analysis of hepatic resection of metastasis originating from gastric adenocarcinoma

Few patients with metastatic gastric cancer have disease that is amenable to curative surgery. Thus far, little is known about liver surgery for metastases arising from gastric adenocarcinoma and prognostic factors. Of 73 patients operated on between 1980 and 1999 for noncolorectal, non-neuroendocrine hepatic metastases, 15 underwent liver resection for gastric adenocarcinoma metastasis. Ten patients underwent synchronous hepatic resection and five underwent metachronous hepatic surgery after a median diseasefree interval of 10 months (range 6.1 to 47.3 months). None of the patients died within the first 30 days after surgery, and the in-hospital mortality rate was 6.7%. Among patients in the synchronous group, 26.7% experienced major complications mainly associated with gastric surgery. Overall median survival was 8.8 months (range 4 to 51 months); two patients survived more than 3 years. Univariate analysis reealed that the appearance of liver metastasis synchronous vs. metachronous), the distribution of liver metastases (unilobar vs. bilobar), and the primary tumor site (proximal vs. distal) were marginally signifiant predictive factors regarding overall survival. Because of its high morbidity, synchronous liver resecion for metastases originating from gastric adenocarcinoma is rarely followed by survival longer than 2 years. Primary tumor localization within the proximal third of the stomach and bilobar liver involvement appear to be predictive of poor outcome. On the other hand, curative resection of metachronous liver metastases may allow long-term survival in selected patients.     

Influence of primary disease factors on outcome after resection of colorectal liver metastases?

The outcome after resection of hepatic metastases from colorectal cancer is influenced not only by factors of metastatic lesions but also those of primary disease. To clarify whether primary disease factors are predictive of post-resection outcome of colorectal liver metastases, 180 patients (male : female = 114 : 66; 61.1 +/-10.5 yrs; synchronous: metachronous = 95 : 85; colon: rectum = 124 : 56 who underwent surgery of colorectal liver metastases in Cancer Institute Hospital from 1995 to 2005 were recruited for analysis. Post-resection outcome of the patients with colorectal liver metastases was significantly influenced by 1) depth of invasion, 2) grade of lymph node metastasis , 3) number of metastatic lymph nodes and 4) Dukes stage of primary disease. The patients with lymph node metastases further than grade 3 showed median survival time of less than 2 years and did not survive longer than 5 years. Thus such condition seemed not warrant resective treatment for liver metastases. In case of synchronous metastatic disease, primary disease information, such as lymph node metastases, depth of invasion, and Dukes stage, were significant predictive factors after hepatectomy. Meanwhile, such factors did not show significant influence in the patients with metachronous liver metastases. In conclusion, influence of primary disease factors should be considered for deciding the indication of hepatectomy for colorectal liver metastases, especially when patients have synchronous lesions.     

Management of patients with hepatic metastases from gastric carcinoma

Many studies have reported the benefit of hepatic resection for metastatic tumors from colorectal cancer. However, the significance of hepatic resection for gastric metastasis has been controversial. Peritoneal metastases were recognized in 40% of gastric cancer patients with liver metastases, and metastatic lesions in both lobes of the liver were seen in 60% of patients. Resection with curability B was performed in only 10% of the all gastric cancer patients with liver metastases. However, the overall 5-year survival rate of curability B resection was more than 30%, suggesting that it is worth while treating metastases of gastric cancer to the liver. Both synchronous and metachronous metastases are indications for hepatectomy. If there is only one liver metastasis, with no peritoneal and paraaortic lymph node metastases, curability B resection can be performed. Although there is no consensus on the method of hepatectomy, wedge resection is satisfactory. As systemic chemotherapy, S-1 + cisplatin results in a response rate of 50% in patients with metastases to the liver. As arterial infusion chemotherapy, the 5-fluorouracil-doxorubicin-mitomycin (FAM) regimen yields a response rate of more than 70% including 15% complete response rate. FAM is thus a superior regimen, but care must be taken to prevent complications resulting from intraarterial infusion of outside the vas due to deviation of the catheter.     

Surgical resection of liver metastases of gastric cancer: an analysis of a 17-year experience with 22 patients

BACKGROUND: The justification for surgical resection of liver metastases from gastric cancer remains controversial. METHODS: Twenty-two patients who underwent 26 hepatectomies for liver metastases of gastric cancer between 1985 and 2001 were analyzed. Fifteen clinicopathologic factors were evaluated with univariate and multivariate analyses for survival after hepatic resection. RESULTS: The overall 1-year, 3-year, and 5-year survival rates after hepatectomy for gastric metastases were 73%, 38%, and 38%, respectively. Five patients survived for more than 3 years without recurrence, 3 of whom had synchronous metastases resected at the time of gastrectomy. The best results after surgical resection for liver metastases of gastric cancer were obtained with solitary metastases less than 5 cm in size. The number of liver metastases (solitary or multiple) was the only significant prognostic factor according to both univariate and multivariate analyses. CONCLUSION: Surgical resection for liver metastases of gastric cancer may be beneficial for patients with a solitary metastasis, whether it is synchronous or metachronous.     

Hepatic Resection for Metastatic Tumors From Gastric Cancer

OBJECTIVE: To assess the surgical results and clinicopathologic features of hepatic metastases from gastric adenocarcinoma to identify patients with a better probability of survival. SUMMARY BACKGROUND DATA: Many studies have reported the benefit of hepatic resection for metastatic tumors from colorectal cancer. However, indications for a surgical approach for gastric adenocarcinoma involving the liver have not been clearly defined. METHODS: Ninety (11%) of 807 patients with primary gastric cancer were diagnosed with synchronous (n = 78) or metachronous (n = 12) hepatic metastases. Of these, 19 underwent 20 resections intended to cure the metastatic lesion in the liver. The clinicopathologic features of the hepatic metastases in, and the surgical results for, the 19 patients were analyzed. RESULTS: The actuarial 1-year, 3-year, and 5-year survival rates after hepatic resection were, respectively, 77%, 34%, and 34%, and three patients survived for more than 5 years after surgery. Solitary and metachronous metastases were significant determinants for a favorable prognosis after hepatic resection. Pathologically, a fibrous pseudocapsule between the tumor and surrounding hepatic parenchyma was found in 13 of the 19 patients (68%). The presence of a peritumoral fibrous pseudocapsule and a well-differentiated histologic type of metastatic nodule were significant prognostic factors. Factors associated with the primary lesion were not significant prognostic determinants in patients who underwent curative resection of the primary cancer. CONCLUSIONS: Solitary and metachronous metastases from gastric cancer should be treated by a surgical approach and confer a better prognosis. A new prognostic factor, the presence of a pseudocapsule, may be helpful in defining indications for postoperative adjuvant treatment.

Surgical treatment of primary lung cancer with synchronous brain metastases

OBJECTIVES: The role of surgical resection for brain metastases from non-small cell lung cancer is evolving. Although resection of primary lung cancer and metachronous brain metastases is superior to other treatment modalities in prolonging survival and disease-free interval, resection of the primary non-small cell lung cancer and synchronous brain metastases is controversial. METHODS: From January 1975 to December 1997, 220 patients underwent surgical treatment for brain metastases from non-small cell lung cancer at our institution. Twenty-eight (12.7%) of these patients underwent surgical resection of synchronous brain metastases and the primary non-small cell lung cancer. RESULTS: The group comprised 18 men and 10 women. Median age was 57 years (range 35-71 years). Twenty-two (78.6%) patients had neurologic symptoms. Craniotomy was performed first in all 28 patients. Median time between craniotomy and thoracotomy was 14 days (range 4-840 days). Pneumonectomy was performed in 4 patients, bilobectomy in 4, lobectomy in 18, and wedge excision in 2. Postoperative complications developed in 6 (21.4%) patients. Cell type was adenocarcinoma in 11 patients, squamous cell carcinoma in 9, and large cell carcinoma in 8. After pulmonary resection, 17 patients had no evidence of lymph node metastases (N0), 5 had hilar metastases (N1), and 6 had mediastinal metastases (N2). Twenty-four (85.7%) patients received postoperative adjuvant therapy. Follow-up was complete in all patients for a median of 24 months (range 2-104 months). Median survival was 24 months (range 2-104). Survival at 1, 2, and 5 years was 64.3%, 54.0%, and 21.4%, respectively. The presence of thoracic lymph node metastases (N1 or N2) significantly affected 5-year survival (P =.001). CONCLUSION: Although the overall survival for patients who have brain metastases from non-small cell lung cancer is poor, surgical resection may prove beneficial in a select group of patients with synchronous brain metastases and lung cancer without lymph node metastases.     

Major hepatic resection for metachronous metastases from colon cancer.

Hepatic resection of metastatic colorectal cancer is being performed with increasing frequency. Reports describe wide variations in survival after resection of solitary of multiple metastases. In 23 consecutive patients having major hepatic resection for metachronous metastases from colorectal cancers, 18 patients had one, two, or three metastases and five had four or more individual metastases; the cure rate of one, two, or three metachronous metastases was comparable to reports of resected solitary simultaneous metastases. The median maximum diameter of metastases in patients both surviving and dead was 7 cm. Features separating surviving from dead patients were resection margins of at least 1 cm and fewer than four metastatic nodules. All patients with four or more hepatic metastases died of disease, 80% with further liver metastases. Only three of 18 (17%) patients with one, two, or three metastases developed further hepatic lesions. This study suggests that the biology of the hepatic metastatic disease is paramount; timing of the hepatic resection is of little importance. Delayed resection of suitable biologic situations does not impair survival opportunities, and early resection of inappropriate biologic situations with more than three hepatic metastases does not improve survival. Therefore, programs of early detection with the use of carcinoembryonic antigen (CEA) screening or "second look" operations will not increase cure rates.     

Analysis of the prognostic factors and evaluation of surgical treatment for synchronous liver metastases from gastric cancer

Background and aims  Whether or not a synchronous resection of liver metastases from gastric cancer provides a survival benefit has been a key issue. We identify the significant prognostic factors and clarify the beneficial effect on the survival of liver surgical treatment. Materials and methods  We reviewed 72 patients who underwent a gastrectomy for gastric cancer with synchronous liver metastases and classified the liver metastases into three grades, such as H1: metastases were limited to one of the lobes, H2: there were a few scattered metastases in both lobes, and H3: there were numerous scattered metastases. Results  H1, 2 metastases, and an absence of peritoneal dissemination (P0) were significantly independent prognostic factors for liver metastases of gastric cancer. In addition, the cumulative 1 and 5-year survival rates of liver surgical treatment (hepatic resection and/or microwave coagulation therapy) were 80.0% and 60.0%, whereas the survival rates for non-hepatic surgical treatment were 36.4% and 0% in 26 patients with H1, 2, and P0. In those patients, the radical operation, the solitary metastatic liver tumor, and no-distant lymph node metastases were independent prognostic determinants of survival. Conclusion  The radical operation including the surgical treatment for metastatic liver tumors should be performed to improve the prognosis in gastric cancer patients with synchronous H1, 2, and P0.

A case with synchronous multiple liver metastases from gastric carcinoma: postoperative long-term disease-free survival

Purpose  We herein report a case with synchronous multiple liver metastases from gastric carcinoma surviving disease-free for more than 10 years after hepatic resection. Methods  A 64-year-old male admitted to our hospital because of constitutional wariness. Preoperative diagnosis was type 1 gastric cancer at the lower third of the stomach and multiple metastases of both hepatic lobes. After we performed distal gastrectomy with regional lymphadenectomy and wedge hepatic resection for eight metastatic liver tumors, he received 5-fluoropyrimidine and platinum-based adjuvant chemotherapy during the early postoperative period. Results  The pathologic examination revealed moderately differentiated gastric adenocarcinoma with regional lymph node metastasis and multiple liver metastases. The postoperative course was uneventful and the patient is doing well without disease recurrence after more than 10 years following surgery. Conclusion  To the best of our knowledge, this patient is the longest disease-free survivor after liver resection for synchronous multiple liver metastases from advanced gastric cancer. In this modern era of developing liver surgery and adjuvant chemotherapy, combination therapy of aggressive surgery and early postoperative adjuvant chemotherapy for advanced gastric cancer with liver metastasis may allow long-term survival in selected patients.     

Treatment strategy for synchronous metastases of colorectal cancer: is hepatic resection after an observation interval appropriate?

Background In cases of synchronous colorectal hepatic metastases, the primary colorectal cancer strongly influences on the metastases. Our treatment policy has been to conduct hepatic resection for the metastases at an interval of 3 months after colorectal resection. We examined the appropriateness of interval hepatic resection for synchronous hepatic metastasis. Materials and methods The subjects were 164 patients who underwent resection of hepatic metastasis of colorectal cancer (synchronous, 70 patients; metachronous, 94 patients). Background factors for hepatic metastasis and postoperative results were compared for synchronous and metachronous cases. Results The cumulative survival rate for 164 patients at 3, 5, and 10 years postoperatively was 71.9%, 51.8%, and 36.6%, and the post-resection recurrence rate in remnant livers was 26.8%. Interval resection for synchronous hepatic metastases was conducted in 49 cases after a mean interval of 131 days. No difference was seen in postoperative outcome between synchronous and metachronous cases. Conclusion The outcome was similarly favorable in cases of synchronous hepatic metastasis and in cases of metachronous metastasis. Delaying resection allows accurate understanding of the number and location of hepatic metastases, and is beneficial in determining candidates for surgery and in selecting surgical procedure.     

Surgical resection of metastatic renal cell carcinoma: The University of Iowa experience

The utility of surgical resection of solitary metastatic sites in renal cell carcinoma remains controversial. Additionally, the small literature detailing the role of surgical management suggests that patients who have surgical resection of metachronous metastases have a better outcome than those presenting synchronously. We reviewed the medical records of all patients with metastatic renal cell carcinoma who underwent nephrectomy at the University of Iowa Hospitals and Clinics between 1980 and 1993. Patients who had undergone surgical resection of metastatic disease, either at presentation or subsequent to their nephrectomy, were identified. Clinical parameters, time to treatment failure, and survival was evaluated. Eighteen patients underwent surgical resection of metastases, 7 were synchronous to their nephrectomy, and 11 developed metachronous metastases. Resected lesions in both groups included metastases to lung, bone, liver, brain, and soft tissue. The median survival of all patients from time of resection to death or last follow-up was 5.7 years (range, 2 days to 10.7+ years). Two patients remain alive, both with recurrent disease at 5.3 and 10.7 years. Mean time from nephrectomy to death was 2.69 years for the synchronous group and 5.97 years for the metachronous group (p = 0.0599). The role of surgical resection in metastatic renal cell carcinoma remains unproven. The survival of this population is significantly longer than that typical for the disease. In our experience there is no difference in time to treatment failure or survival between synchronous and metachronous resection of metastatic disease.     

The primary tumour resection with extended D3 lymph node dissection, metastases of synchronous metastatic colorectal cancer

The progress in colorectal cancer treatment of IV stage that was shown in last decades was mainly due to modern chemotherapy schemes and aggressive surgical approach towards distant metastatic lesions. Meanwhile less attention is paid to primary tumour treatment - the questions of necessity and volume of its resection are still open. The AIM of this study was to evaluate safety and oncologic effectiveness of primary tumour resection with D3 lymph node dissection in synchronous metastatic colorectal cancer. Patients with colorectal cancer and synchronous metastatic lesion of distant organs who underwent surgical resection of primary tumour were chosen from prospectively collected department database. The analysis of short-term and long-term results of resections with and without extended D3 lymph node dissection and prognostic factors affecting overall survival was carried out. From 2006 to 2011 total of 190 patients underwent primary tumour resection, 157 (82.6%) among them - with extended D3 lymph node dissection. Twenty one patient (11%) developed postoperative complications that required reintervention, 30-days mortality rate was 2.6%. Three-year cumulative overall survival was 37%, median survival - 22 months (25 months with extended lymph node dissection and 4 months without, p<0.001). Univariate analysis revealed following statistically significant prognostic factors improving overall survival: metastatic lesions in one distant organ, solitary haematogenous nodes, extended D3 lymph node dissection, postoperative chemotherapy, resection of metastatic lesions. Removal of primary tumour with extended lymph node dissection in metastatic colorectal cancer doesn't increase the number of postoperative complications and mortality. Performing D3 lymph node dissection favours increase of median survival and is a significant prognostic factor influencing outcomes.     

胃癌同时性肝转移的临床病理分析和外科治疗效果评价

目的分析影响胃癌同时性肝转移的临床病理因素，探讨胃癌肝转移的治疗方法。方法回顾性分析1994年8月至2004年2月间收治的44例胃癌同时性肝转移患者的病例资料，并与同期收治的无转移的576例胃癌病例资料进行比较，分析影响同时性肝转移的临床病理因素。对胃癌肝转移根治性切除、姑息性切除和探查性手术的生存状况进行分析比较。结果单因素分析显示，腹水、盆结节、腹膜侵犯、浆膜浸润、淋巴结转移、周围脏器受累以及肿瘤Borrmarm分型、浸润深度都与胃癌肝转移有关（P〈0．01）；Logistic回归分析发现，腹膜侵犯（P=0．003）、浆膜浸润（P=0．000）、淋巴结转移（P=0．081）是影响胃癌肝转移最重要的因素。本组胃癌肝转移患者行根治性切除16例（36．4％），姑息性切除15例（34．1），探察性手术13例（29．5％）；中位生存期分别为19．5、11．0和6．2个月：3组比较差异有统计学意义（P〈0．05）。结论胃癌肝转移是胃癌的晚期事件；根治性切除胃癌原发病灶和肝转移灶，仍然可以明显提高患者的生存率。

Resection of brain metastases from non-small-cell lung carcinoma. Results of therapy. Memorial Sloan-Kettering Cancer Center Thoracic Surgical Staff.

The treatment of patients with a solitary brain metastasis has been evolving, with most centers recommending resection in patients with good performance status. To evaluate the results of resection of brain metastases from non-small-cell lung cancer, we reviewed our 16-year experience with 185 consecutive patients undergoing resection of brain metastases from 1974 to 1989, inclusive. There were 89 men and 96 women; ages ranged from 34 to 75 years (median 54). Sixty-five (35%) had synchronous and 120 (65%) metachronous brain metastases. Discounting the brain metastasis, 68 patients (37%) had stage I, 13 (7%) stage II, 62 (33%) stage IIIA, 30 (16%) stage IIIB, and 12 (6%) stage IV carcinoma. There was no significant difference in age, locoregional stage (TN), or histologic features in patients with synchronous versus metachronous lesions. The overall survival rates (n = 185) were as follows: 1 year, 55%; 2 years, 27%; 3 years, 18%; 5 years, 13%; and 10 years, 7% (median 14 months). There was no significant difference in survival between patients with synchronous and metachronous lesions. To evaluate the impact of locoregional stage and treatment of the primary site, we analyzed only those patients with synchronous brain metastases. Multivariate analysis demonstrated that locoregional stage had no significant effect on survival (p = 0.97), but complete resection of the primary disease significantly prolonged survival (p = 0.002). Therefore complete resection, and not stage, of the locoregional primary lesion is the primary determinant of survival in patients undergoing resection of brain metastases from non-small-cell lung cancer.     

Long-Term Survival Achieved by Repeated Resections of Metachronous Pulmonary and Adrenal Metastases of α-Fetoprotein-Producing Gastric Cancer: Report of a Case

We report a case of long-term survival achieved by repeated resections of metastases from -fetoprotein (AFP)-producing gastric cancer. A 59-year-old man initially underwent total gastrectomy with lymph node dissection and resection of the spleen and left adrenal gland, for an advanced AFP-producing gastric cancer. A solitary pulmonary metastasis was resected 2 years later, and then a right adrenal gland metastasis, an inferior vena cava thrombus, and another pulmonary metastasis were resected 6 months, 1 year, and 8 months after each other, respectively. Thus, the patient has survived for 7 years and no further evidence of disease was found at his last follow-up examination. To the best of our knowledge, this is the first case of AFP-producing gastric cancer resulting in metachronous solitary pulmonary and adrenal gland metastases, but not liver metastasis. We report this case to show that for selected cases, surgical resection of these metastases is feasible and may extend survival.
