The treatment of metastatic renal cell carcinoma still represents a widely debated issue due to the introduction of several immunotherapies. To confirm again a role for resection of pulmonary metastases for such tumors, we reviewed our institutional experience. Between 1992 and 2007, eight patients with pulmonary metastases from renal cell carcinoma underwent complete pulmonary resection. All patients had undergone curative resection of their primary renal cell carcinomas and also had obtained or had obtainable locoregional control of their primaries. Various perioperative variables were investigated retrospectively. Disease-free interval varied from 25 to 156 months, with a median of 73 months. In three patients, lung metastases were found to be unilateral and solitary. Four patients presented two metastases in the unilateral lungs. One patient showed five metastases in the bilateral lungs. Six patients underwent wedge resection or segmentectomy, while two patients underwent more than lobectomy. Five patients showed recurrence after pulmonary metastasectomy. Five-year and 10-year overall survival rate was 83.3% and 41.7%, respectively, while 3-year and 5-year disease-free survival rate was 35.0% and 17.5%, respectively. Our study suggested that pulmonary metastasectomy for renal cell carcinoma might be well justified. 相似文献

OBJECTIVE: Surgical resection is an important form of treatment for pulmonary metastases from colorectal carcinoma. We analyzed the clinical course, outcome, and prognostic factors after surgery. METHODS: Between 1985 and 2000, 167 patients (103 men, 64 women) underwent complete pulmonary resection of metastatic colorectal carcinoma. Only patients who met the criteria for potentially curative operation, in particular, control of the primary tumor, ability to resect all metastatic disease, and no other extrapulmonary metastases, were included. RESULTS: The overall 5-year survival was 32.4%. A significantly longer survival was observed in multivariate analysis in patients without lymph node involvement compared with patients with pulmonary or mediastinal lymph node metastases or both. The number of pulmonary metastases significantly influenced survival. In patients with a solitary metastasis, we observed a 5-year survival of 45%, whereas the rate was 19.8% in patients with more than a single metastasis. In multivariate analysis, we also found the prethoracotomy carcinoembryonic antigen serum level to be an independent significant prognostic factor for survival. In patients with a serum carcinoembryonic antigen level exceeding 5 ng/mL and in patients with a serum carcinoembryonic antigen level in the normal range, the 5-year survivals were 22.7% and 48.3%, respectively. CONCLUSIONS: We conclude that pulmonary resection of metastatic colorectal carcinoma is safe and results in long-term survival. Thoracic lymph node metastases, serum carcinoembryonic antigen level before metastasectomy, and the number of pulmonary metastases were identified as prognosis-related criteria for surgery. 相似文献

BACKGROUND: This study aims to clarify which patients would benefit by surgery for pulmonary metastases from colorectal carcinoma. METHODS: A retrospective study was undertaken in 25 patients who had undergone complete resection. In all cases, prethoracotomy carcinoembryonic antigen (CEA) level was measured and mediastinal or hilar lymph nodes were histologically examined. RESULTS: Overall 5-year survival was 39.2%. The 5-year survival rate for patients with a normal CEA level was 61.1%, as compared with 19.0% for patients with an elevated CEA level (p = 0.0423). The 5-year survival rate for patients without a lymph node metastasis was 49.5%, as compared with 14.3% for patients with a lymph node metastasis (p = 0.0032). No lymph node metastasis was a predictor of longer survival by univariate and multivariate analyses. The primary site, disease-free interval, and number and size of the metastasis were not significant prognostic factors. CONCLUSIONS: A resection for pulmonary metastasis from colorectal carcinoma is effective in patients with a normal CEA level and without a lymph node metastasis. 相似文献

Prognostic factors and survival after pulmonary resection of metastatic renal cell carcinoma 总被引:3,自引:0,他引:3
OBJECTIVE: Pulmonary metastasectomy as well as immunotherapy have reproducible, albeit limited efficacy in advanced renal cell carcinoma (RCC). We examined whether metastasectomy improved overall survival compared with results of immunotherapy. METHODS: Between 1975 and 2003, 64 patients (41 men, 23 women) underwent pulmonary resection of metastatic RCC. Only patients who met the criteria for potentially curative operation, that means, control of primary tumor, ability to resect metastatic disease and no other extrapulmonary metastases, were included. RESULTS: The overall 5-year survival was 33.4% (median survival: 39.2 months). A significant longer survival was observed using multivariate analysis in patients with complete pulmonary resection (R0), with a 5-year survival of 39.9% and a median survival of 46.6 months in correlation to patients with incomplete resection (5-year survival 0%, median survival 13.3 months). In multivariate analysis patients with synchronous metastases had a significant worse prognosis in correlation to patients with metachronous metastases. The 5-year survival of curative resected patients with metachronous metastases was 43.7% versus 0% for synchronous metastases, respectively. In patients with solitary metastasis and R0 resection, we observed a 5-year survival of 49%, whereas the rate was 23% in patients with more than a single metastasis. When establishing prognostic groups as suggested by the International Registry based on the risk factors disease-free interval, number of metastasis and complete resection the group with the best prognosis showed a 5-year survival of 52% (median survival 75.2 months). CONCLUSION: Metastasectomy nowadays is the best treatment option in cases with technical resectable metastases with as much as possible good prognostic factors (metachronous metastases with long DFI, number up to 6 metastases). 相似文献

The results of pulmonary resection for metastatic pulmonary lesions in our institution are reviewed. Over the period of ten years 43 patients underwent 46 thoracotomies with a 5 years survival rate of 40.8%. The most significant predictors of survival were type of primary tumor, number of lesions removed and disease-free interval, while there were no statistically significant difference in survival rates between partial resection and lobectomy. Recurrence in the early postoperative period was often observed in the patients with bilateral pulmonary metastases and their 5 years survival rate was as low as 21.9%. Though multiple lung metastases is not contraindication for pulmonary resection, we should be prudent to operate for those patients with multiple lung metastases. Our results suggest that the patient with solitary lesion, long disease-free interval and no metastases to mediastinal lymph nodes is the best candidate for resection of the metastatic pulmonary lesions. 相似文献

BACKGROUND: Pulmonary metastasectomy has become the standard therapy for various metastatic malignancies to the lungs; however, little data have been available about lung metastasectomy for head and neck cancers. To confirm a role for resection of pulmonary metastases for such tumors, we reviewed our institutional experience. METHODS: Between 1991 and 2007, 20 patients with pulmonary metastases from head and neck cancers underwent complete pulmonary resection. All patients had obtained or had obtainable locoregional control of their primary head and neck cancers. Various perioperative variables were investigated retrospectively to analyze the prognostic factors for overall survival and disease-free survival after metastasectomy. RESULTS: Of the 20 patients, 10 (50%) had squamous cell carcinoma, 7 (35%) had adenoid cystic carcinoma, and 3 had miscellaneous carcinomas. The median disease-free interval from the time of treatment of the head and neck primary cancers to the development of pulmonary metastases was 27 months. Overall survival rate after metastasectomy was 59.4% at 5 years and 47.5% at 10 years, respectively. Disease-free survival rate was 25.0% at 5 years after pulmonary resection. A disease-free interval equal to or longer than 12 months was a significantly favorable prognostic factor for both overall survival and disease-free survival (p = 0.02 and 0.01, respectively). Patients with squamous cell carcinoma and male sex showed a worse overall survival (p = 0.04 and 0.03, respectively). CONCLUSION: The current practice of pulmonary metastasectomy for head and neck cancers in our institution was well justified. A disease-free interval equal to or longer than 12 months, nonsquamous cell carcinoma, and female sex might be relevant to a better prognosis. 相似文献

OBJECTIVE: Metastatic breast cancer is still defined as an incurable disease. Although the prognosis after resection of isolated metastases to the lung is much better than after chemotherapy most oncologists and gynecologists disapprove of lung metastasectomy. METHODS: In order to summarize the experience of pulmonary metastatic surgery and to achieve more relevant data by an increased number of cases, we evaluate the data of the International Registry of Lung Metastases of 467 patients having lung metastases from breast cancer with regard to long-term survival and prognostic factors. RESULTS: In 84% a complete metastatic resection was possible. The survival rates are 38% after 5 years, 22% after 10 years, and 20% after 15 years. Prognostic factors are a disease-free interval of > or = 36 months with 5-year survival of 45%, a 10-year survival of 26% and a 15-year survival of 21% (P=0.0001), solitary lung metastasis is associated with a survival rate of 44% after 5 years and of 23% after 10 and 15 years, but this is not statistically significant compared to multiple metastases. When establishing prognostic groups as suggested by Pastorino and the International Registry of Lung Metastases based on the risk factors disease-free interval, number of metastases and complete resection the group with the best prognosis showed 5-year survival of 50%, 10- and 15-year survival of 26% with a median survival of 59 months. CONCLUSION: Considering the low morbidity and mortality rate, we think that lung metastasectomy today is the best treatment option in selected cases of lung metastases from breast cancer. 相似文献

Long-term survival after resection of pulmonary metastases from carcinoma of the breast. 总被引:2,自引:0,他引:2

Resection of isolated pulmonary metastases may yield improved survival in select patients. Between 1981 and 1991, 44 women (median age, 55 years) with a history of breast cancer underwent 47 thoracotomies with no operative deaths and only three minor postoperative complications (3/47, 6.4%). Confirmation of the metastatic origin of the lung lesion was made by direct histological comparison with the primary. Three patients had benign nodules and were excluded, and 4 patients had less than complete resection at thoracotomy. The median survival after thoracotomy of the remaining 37 patients with completely resected metastases was 47 +/- 5.5 months, and their actuarial 5-year survival was 49.5%. Patients with a disease-free interval of longer than 12 months had a longer survival (median survival, 82 +/- 6 months; 5-year survival, 57%) than patients with a disease-free interval of 12 months or less (median survival, 15 +/- 3.6 months; 5-year survival, 0%) (p = 0.004). Patients with estrogen receptor-positive status (n = 14) tended to have longer survival after resection than patients with estrogen receptor-negative status (n = 15) (median survival, 81 +/- 9 months versus 23 +/- 6 months, respectively; p = 0.098). Other clinical variables analyzed did not predict survival after thoracotomy. We conclude that resection of pulmonary metastases in patients with breast cancer can be done safely and may result in long-term survival for a substantial number of patients. Patients with a disease-free interval of longer than 12 months have an excellent prognosis after complete resection. 相似文献

OBJECTIVE: To define the most reliable prognostic factor, we studied the 5-year survival of patients after resection of pulmonary metastases from colorectal cancer in relation to various prognostic factors, including vascular endothelial growth factor expression in primary and metastatic tumors. METHODS: A retrospective study was undertaken in 49 patients who had undergone complete resection of pulmonary metastasis from colorectal carcinoma. All patients were retrospectively analyzed for sex, age, location and stage of primary tumor, number of pulmonary metastases, type of pulmonary resection, size of metastatic tumor, lymph node metastasis, and prethoracotomy carcinoembryonic antigen level. Furthermore, vascular endothelial growth factor expression of both primary and metastatic tumors was investigated. RESULTS: Overall 5-year survival was 34.3%. In the univariate analysis the number of pulmonary metastases (P =.007) and vascular endothelial growth factor expression in metastatic tumors (P =.008) and primary colorectal tumors (P =.011) were significantly associated with poor survival. In the multivariate analysis the number of pulmonary metastases (P =.0031), vascular endothelial growth factor expression in metastatic tumors (P =.0057), and stage of primary tumor (P =.0321) were characteristics that retained a significant independent prognostic effect on overall survival. A statistically significant difference was not found in the 5-year survival of patients with solitary and negative vascular endothelial growth factor expression in metastatic tumors (59.1%) versus those with multiple and positive vascular endothelial growth factor expression in metastatic tumors (10.0%; P 相似文献

This study was undertaken to review the long-term results of multivisceral resection of locally advanced colorectal carcinoma. Between 1964 and 1980, 1042 patients underwent exploratory surgery for colorectal cancer. Of these, 58 patients (5.5%) underwent curative multivisceral resection for suspected contiguous invasion by the primary tumor. Follow-up was complete for all patients. The primary tumors were located in the rectum (38 patients), sigmoid (9 patients), left colon (6 patients), and right colon (5 patients). En bloc resection of other viscera included uterus, adnexa, bladder, vagina, small intestine, abdominal wall, liver, stomach, kidney, and ureter. The operative morbidity and mortality rates were 31% and 1.7%, respectively. Resection margins were free of tumor in 54 patients. In the four patients with tumor-positive resection margins, recurrence of disease was evident between 8 and 22 weeks after surgery (mean survival time, 8.2 months). Carcinomatous invasion of the resected contiguous organ was confirmed in 49 patients (84%). The mean survival time for patients without lymph node metastases was 100.7 months, but it was only 16.2 months (p less than 0.01) for patients with lymph node metastases. Actuarial 5-year disease-free survival rate for patients without lymph node metastases was 76% (36 of 47 patients). None of the patients (0 of 11) with lymph node metastases survived for 5 years. Three of 36 of the 5-year survivors experienced recurrence of disease before the seventh postoperative year; no cancer-related deaths occurred between 7 and 25 years. These data suggest that survival in locally advanced colorectal carcinoma is more dependent on lymph node status than on the extent of local invasion. Effective disease control associated with survival in the long term can be achieved by multivisceral resection. 相似文献

BACKGROUND: Until now no conclusive data exist regarding the factors influencing long-term survival after pulmonary resection of renal cell carcinoma metastases. The aim of the present study, therefore, was to discover definitive prognostic factors for survival using a large and homogeneous single center patient cohort. METHODS: Between 1980 and 2000, 105 patients, after curative resection of lung metastases from renal cell carcinoma, were followed in this long-term study. These patients underwent a total of 150 surgical procedures. Survival analysis was done using the Kaplan-Meier method and the log-rank test. Multivariate analysis of prognostic factors was performed using the Cox multivariate proportional hazard model. RESULTS: Median survival after curative resection reached 43 months (range, 1 to 218 months). Survival at 3, 5, and 10 years was 54%, 40%, and 33%, respectively. Univariate analysis revealed that a complete resection, a less than 4-cm diameter of the metastases and tumor-free lymph nodes at the time of primary operation, were highly significant dependent prognostic factors (p < 0.001). These factors were also shown to be independent prognostic factors as suggested by multivariate analysis (p < 0.05). CONCLUSIONS: The size of the metastatic nodule, the completeness of pulmonary resection, and the lymph node status at the time of nephrectomy are the most important prognostic factors that influence survival after resection of pulmonary metastases. Recurrence of resectable pulmonary metastases does not impair survival, thus favoring repeated resection in patients with recurrent disease. 相似文献

OBJECTIVE: To examine the experience of pulmonary resections for colorectal metastases at the McGill University Health Centre. DESIGN: A chart review. PATIENTS: Forty-nine patients treated surgically between 1975 and 1998 for pulmonary metastases from colorectal cancer. INTERVENTION: Thoracotomy with pulmonary resection. OUTCOME MEASURES: Survival of patients with various preoperative and post operative clinical variables. RESULTS: The perioperative death rate was 4%. Overall 5- and 10-year survival rates were 55% and 40% respectively. The mean interval between the initial colonic resection and resection of pulmonary metastases (discase-free interval) was 36 months. The 7 patients who also under went resection of extrapulmonary metastases had a 5-year survival rate of 52%. Significant preoperative variables that carried a poor prognosis included the following: more than one pulmonary lesion, a disease-free interval of less than 2 years, and moderately or poorly differentiated colorectal cancer. The 16 patients who received chemotherapy after their thoracotomy had a 5-year survival rate of 51% compared with 54% for the 33 patients who did not receive chemotherapy. Recurrent resections of pulmonary lesions did not reduce survival. CONCLUSIONS: Pulmonary resection for metastatic colorectal cancer is both effective and safe. Resectable extrapulmonary metastases and pulmonary recurrence should not preclude lung resection. Postoperative chemotherapy has no survival benefit. Preoperative variables should guide the clinician when considering surgical intervention. 相似文献

Thoracotomy for metastatic malignant melanoma of the lung. 总被引:6,自引:0,他引:6
The outcome of 29 patients who underwent lung resection for treatment of metastatic malignant melanoma from January 1976 to November 1988 was studied. Twenty-two patients underwent total resection for cure of all apparent metastatic disease, whereas seven patients did not undergo total resection. Of the 22 patients who underwent curative resection, the median survival was 11 months, with a 2-year survival of 13.6% and a 5-year survival of 4.5%. Four patients who underwent curative resection are currently alive and free of disease, with one patient surviving more than 10 years. The patients who underwent palliative resection had a median survival of 5 months, only one patient living longer than 10 months. The difference in survival of the patients who underwent curative resection compared with palliative resection was statistically significant. The thickness of the primary cutaneous malignant melanoma, the presence of regional lymph node metastases, the disease-free interval from primary diagnosis to metastatic pulmonary disease, and whether one or two metastatic nodules were removed during curative lung resection were not statistically significant in altering survival. These results demonstrate that although prolonged survival for metastatic melanoma is rare, lung resection in selected patients may be associated with long-term survival. 相似文献

Based on a large single-center follow-up database, we evaluated the long-term results after curative resection of pulmonary metastases from renal cancer. During a 20-year period, 105 patients underwent a total of 150 resections with curative intention. Hospital mortality was 0.95%, 5- and 10-year survival rates were 40% and 33%, respectively. Significant prognostic relevance was shown for complete pulmonary resection, lymph node involvement upon primary resection as well as size of the resected lung metastasis. Our findings of low perioperative morbidity and mortality rates lead us to propose that in patients without additional metastases curative resection of pulmonary lesions should be considered. Moreover, recurrent pulmonary metastases should also be considered for surgical treatment since resection for cure significantly improves survival in these patients. 相似文献

Background The impact of lymph node metastases on survival in extremity soft tissue sarcomas has been studied for a long time with controversial
results. The purpose of this study was to compare survival of patients with initial lymph node metastases with those having
lymph node or distant metastases or both after initial curative surgery.
Methods Patients treated between 1995 and 2000 for extremity soft tissue sarcoma were retrospectively studied in four groups: those
with metastatic regional lymph nodes at the time of diagnosis, those with only regional lymph node recurrences, those with
only distant metastatic relapses, and those with both regional lymph node recurrences and distant metastatic relapses, all
of the last three groups after initial curative surgery. The impact of timing of lymph node metastases on disease-free and
overall survival was evaluated.
Results A total of 110 patients (73 men) with a median age of 45 years were eligible for the study. Three-year disease-free survival
was significantly longer in patients with initial regional lymph node metastases than in patients with only lymph node recurrences
after curative surgery (p = 0.04) and patients with initial (p = 0.0002) and recurrent (p = 0.0004) regional lymph node metastases had longer disease-free survival than patients with distant metastases. Overall
survival difference between patients with initial regional lymph node metastases and patients with only lymph node recurrences
after curative surgery was significant at 5 years (p = 0.01).
Conclusions It is logical to separate patients with initial lymph node metastases from those with distant metastases in staging and to
treat patients with initial lymph node metastases with radical surgical interventions if complete tumor resection seems feasible. 相似文献

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. 相似文献

Between 1985 and 1991, 23 patients underwent resection of pulmonary metastases from renal cell carcinoma, of whom 18 had previously received interleukin-2 based immunotherapies. Mean survival from exploration in all patients was 43 months. Survival after resection did not correlate with the number of nodules on preoperative tomograms, the number of nodules resected, or the disease-free interval. Patients who underwent complete resection of metastatic disease (n = 15), however, had a significantly longer survival (mean, 49 months; median not yet achieved) compared with patients with incomplete resection (median, 16 months) (p2 = 0.02). Two of the 15 patients who underwent curative resections are presently free of disease greater than 45 months after exploration. These data support surgical resection of isolated pulmonary metastatic disease from renal cell cancer. 相似文献

Methods The data of 19 patients diagnosed with renal cell carcinoma with regional lymph node metastases at diagnosis from January 2004 to December 2008 were reviewed.The median age was 57 years (29-77).The study group included 15 males and four females.The primary tumor was located in the left kidney in 12 patients and fight in seven patients.The median maximam diameter of retroperitoneal lymph nodes was 2.8 cm(1.5-5.0).The lymph nodes in four patients were not detected by the preoperative image examination,but were confirmed by intraoperative exploration.Eleven cases had enlarged retroperitoneal lymph nodes resected and eight had regional lymph nodes dissected. Results The patients with regional lymph node metastases at diagnosis of renal celI carcinoma accounted for 1.6% (19/1213) of the total renal cell carcinoma cases.With a median follow-up of 34 months,six patients were survival without progression,and seven were survival with progression.giving a 5-year survival rate of 68.4%.The survival and recurrence rates after surgery were not significantly different by Fisher test(P=0.644 and 0.319 respectively) between the patients who underwent retroperitoneal regional lymph node dissection and those who underwent enlarged lymph node resection. Condmiom Renal cell carcinoma with regional lymph node metastasis at diagnosis is uncommon.Some patients may achieve long-term tumor-free survival through regional lymph node dissection or enlarged Iymph nodes resection. 相似文献

OBJECTIVE: To evaluate retrospectively the long-term results of an approach consisting of performing surgery in every patient in whom radical removal of all metastatic disease was technically feasible. SUMMARY BACKGROUND DATA: The indications for surgical resection for liver metastases from colorectal cancer remain controversial. Several clinical risk factors have been reported to influence survival. METHODS: Between March 1980 and December 1997, 235 patients underwent hepatic resection for metastatic colorectal cancer. Survival rates and disease-free survival as a function of clinical and pathologic determinants were examined retrospectively with univariate and multivariate analyses. RESULTS: The overall 3-, 5-, 10-, and 15-year survival rates were 51%, 38%, 26%, and 24%, respectively. The stage of the primary tumor, lymph node metastasis, and multiple nodules were significantly associated with a poor prognosis in both univariate and multivariate analyses. Disease-free survival was significantly influenced by lymph node metastasis, a short interval between treatment of the primary and metastatic tumors, and a high preoperative level of carcinoembryonic antigen. The 10-year survival rate of patients with four or more nodules (29%) was better than that of patients with two or three nodules (16%), and similar to that of patients with a solitary lesion (32%). CONCLUSIONS: Surgical resection is useful for treating liver metastases from colorectal cancer. Although multiple metastases significantly impaired the prognosis, the life expectancy of patients with four or more nodules mandates removal. 相似文献
