Results of surgical resection of pulmonary metastases of squamous cell carcinoma of the head and neck.

In this retrospective review of 58 patients (12 females and 46 males) with pulmonary metastases of squamous cell carcinoma of the head and neck treated between January 1, 1970, and December 31, 1989, we evaluated their clinical courses and analyzed the outcomes of those who underwent pulmonary resection. For the entire group of patients, factors predictive of survival in those patients with a diagnosis of pulmonary metastases included pulmonary resection of metastases (p = 0.0001), locoregional control of the head and neck primary tumor at the time of diagnosis of pulmonary metastases (p = 0.007), TNM stage of the head and neck primary tumor (p = 0.02), a single nodule seen on the chest radiograph (p = 0.02), and disease-free interval (DFI) from the primary tumor of the head and neck of 2 years or more (p = 0.05). Twenty-four of 58 patients underwent thoracotomy for resection of metastases. Four (17%) were found to have a second primary tumor of the lung. Of the 20 remaining patients who underwent explorative surgery for possible pulmonary resection, 18 (90%) underwent complete resection of all malignant disease with an estimated 5-year survival of 29%. In these patients, a DFI of less than 1 year was associated with a 5-year survival rate of 0%, whereas a DFI of 1 to 2 years was associated with a 5-year survival rate of 43% and a DFI of 2 years or longer had a 5-year survival rate of 33%. The number of malignant pulmonary nodules that were resected ranged from one to five and was not significant in predicting survival (p = 0.19). Of eight patients who underwent the resection of more than one malignant pulmonary nodule, 50% survived 2 years, but none survived 5 years. Resection of a solitary pulmonary metastasis from squamous cell carcinoma of the head and neck resulted in long-term survival in selected patients. Important prognostic factors included locoregional control of the head and neck primary tumor, the number of nodules seen on chest radiograph, the TNM stage of the primary tumor, and the DFI from the head and neck primary tumor. The value of resection in patients with more than one malignant pulmonary nodule remains to be defined for this group of patients.     

The role of resection in the treatment of pulmonary metastases from Ewing's sarcoma

We have investigated the role of resection in the treatment of patients with isolated pulmonary metastases from Ewing's sarcoma. In a retrospective review, 19 patients with the diagnosis of Ewing's sarcoma treated at the National Cancer Institute from 1965 to 1985 who underwent chest exploration for resection of pulmonary nodules were evaluated. Ten patients (53%) were made disease free by resection of pulmonary metastases, six patients (32%) were found to have unresectable disease, and three patients (16%) were found to have benign pulmonary disease. The actuarial 5 year survival rate of the 10 patients successfully made disease free by resection was 15%, and the median survival of this group was 28 months. In contrast, the median survival of the six patients not made disease free was 12 months, and no patient with residual disease was alive 22 months after thoracotomy (p2 = 0.0047). There were no postoperative deaths and only three minor postoperative complications for 25 operative procedures. Various prognostic variables were analyzed to determine their influence on postmetastasectomy survival. There was no difference in postmetastasectomy survival between patients who underwent resection of synchronous versus metachronous pulmonary metastases (p2 = 0.90). Patients who underwent resection of fewer than four malignant nodules had a significantly longer postmetastasectomy disease-free survival (p2 = 0.0019) and overall survival (p2 = 0.06) than those undergoing resection of four or more nodules. Patients who underwent resection of metastases that developed during chemotherapy had a significantly shorter postmetastasectomy survival that those who underwent resection of metastases that developed after chemotherapy (p2 = 0.0295). Our data show that selected patients with Ewing's sarcoma metastatic to the lungs may benefit from an aggressive surgical approach. Also, a significant proportion of these patients will have benign pulmonary disease and can thus avoid additional intensive systemic therapy.     

Results of surgical treatment of pulmonary metastases from soft tissue sarcomas

Background The surgical removal of pulmonary metastases forms part of an interdisciplinary oncological treatment concept. Methods Between January 1, 1972 and December 31, 1990, 757 operations were performed in 657 patients and retrospectively analyzed. Results The pulmonary metastases resected were from a carcinoma in 475 patients (72%), and from a sarcoma in 182 patients (28%), 90 of whom (14%) had a soft tissue sarcoma. Irrespective of the primary tumor, the 30-day mortality was 2.2% for the whole group of patients and for the soft tissue sarcoma group alone. The 5-year survival rate for the whole group of 657 patients was 30%, while that of the patients treated for metastases from a soft tissue sarcoma was 21% (median survival 457 days), this was significantly improved after surgery which was carried out with the objective of cure (5-year survival 26%, median survival 676 days). In patients with a disease-free interval of more than 3 years (5-year survival rate 28%, median survival 743 days) the prognosis was better, but the differences were not statistically significant. With respect to sex, primary tumor, number of metastases, side effect, resection technique and adjuvant radiation and/or chemotherapy of the pulmonary metastases, there were no differences in prognosis. Conclusions Even for smaller, homogeneous groups of patients, it was necessary to determine prognostic factors, regardless of the location and histology of the primary site, since this makes it possible to optimize therapeutic indications and management.     

Outcomes after resection of synchronous or metachronous hepatic and pulmonary colorectal metastases

BACKGROUND: Surgical resection of isolated hepatic or pulmonary colorectal metastases prolongs survival in selected patients. But the benefits of resection and appropriate selection criteria in patients who develop both hepatic and pulmonary metastases are ill defined. STUDY DESIGN: Data were prospectively collected from 131 patients with colorectal cancer who underwent resection of both hepatic and pulmonary metastases over a 20-year period. Median followup was 6.6 years from the time of resection of the primary tumor. Patient, treatment, and outcomes variables were analyzed using log-rank, Cox regression, and Kaplan-Meier methods. RESULTS: The site of first metastasis was the liver in 65% of patients, the lung in 11%, and both simultaneously in 24%. Multiple hepatic metastases were present in 51% of patients, and multiple pulmonary metastases were found in 48%. Hepatic lobectomy or trisegmentectomy was required in 61% of patients; most lung metastases (80%) were treated with wedge excisions. Median survival rates from resection of the primary disease, first site of metastasis, and second site of metastasis were 6.9, 5.0, and 3.3 years, respectively. After resection of disease at the second site of metastasis, the 1-, 3-, 5-, and 10-year disease-specific survival rates were 91%, 55%, 31%, and 19%, respectively. An analysis of prognostic factors revealed that survival was significantly longer when the disease-free interval between the development of the first and second sites of metastases exceeded 1 year, in patients with a single liver metastasis, and in patients younger than 55 years old. CONCLUSIONS: Surgical resection of both hepatic and pulmonary colorectal metastases is associated with prolonged survival in selected patients. Patients with a longer disease-free interval between metastases and those with single liver lesions had the best outcomes.     

The significance of surgical resection for pulmonary metastasis from hepatocellular carcinoma

BACKGROUND: Pulmonary metastasis, which is the most common type of extrahepatic recurrence of hepatocellular carcinoma (HCC), has been considered unsuitable for surgical resection because most pulmonary metastases are multiple. Until now there have been few reports about surgical resection for pulmonary metastasis from HCC. The aim of the present study was to evaluate the significance of surgical resection for pulmonary metastasis from HCC. METHODS: Among 615 patients who underwent radical hepatic resection for HCC in our hospital over the past 15 years, 8 patients who had developed 1 or 2 pulmonary metastases underwent pulmonary resection for the pulmonary metastases (resection group), the other 6 patients who had developed 1 or 2 pulmonary metastases did not undergo pulmonary resection (nonresection group). The clinicopathologic features and long-term prognosis of the resection group were examined and compared with those of the nonresection group. RESULTS: In the resection group, although intrahepatic recurrences were present before the diagnosis of pulmonary metastasis in 4 patients, they were well controlled by repeated transarterial chemoembolization and/or further hepatic resections. The average survival periods after the pulmonary resection and after the initial hepatic resection were 29 months (range, 5-80 mo) and 61 months (range, 24-133 mo), respectively. No patients in the resection group showed pulmonary recurrence after the pulmonary resection, and the cause of death of the patients in the resection group was not pulmonary metastasis. The survival rate of patients in the resection group was significantly better than that in the nonresection group. CONCLUSIONS: It may be concluded that surgical resection for pulmonary metastasis from HCC might be beneficial in selected patients.     

Pulmonary resection for metastatic breast cancer.

Thirty-three patients treated primarily with surgical excision of pulmonary metastases from breast cancer were compared with 30 patients treated primarily with systemic chemohormonal therapy. Treatment for patients in the surgical group included pulmonary resection alone in 20, resection plus adjuvant systemic therapy in nine, and resection plus adjuvant radiation therapy in four. Treatment for patients in the medical group included systemic therapy alone in 22 and systemic therapy plus local radiation therapy in eight. Mean survival in the surgical group was significantly longer than that in the medical group, even when only those patients who manifested single pulmonary nodules were compared (58 months vs 34 months). The overall 5-year survival rate after treatment of lung metastasis was significantly greater for the surgical group than for the medical group (36% vs 11%). The results of this study indicate that surgical resection should be considered in patients with breast cancer who develop operable pulmonary metastases without evidence for concomitant extrapulmonary disease. In selected patients, such therapy may result in a survival benefit.     

Complete resection of isolated lung metastasis from breast carcinoma results in a strong increase in survival

BACKGROUND: Surgical treatment of pulmonary resection for metastatic disease has been proven a valuable therapeutic concept for a variety of neoplasms. Concerning breast cancer, at least 25% of patients develop distant metastases. In spite of increasingly sophisticated palliative therapies, the survival of these patients did not appear significantly prolonged during the last 25 years (19-32 months following diagnosis) and about 95% die from metastatic disease. METHODS: Between 1977 and 1997, three epidemiological comparable groups out of a total of 125 patients of our clinic were treated for isolated pulmonary metastasis following breast cancer. Complete data from 96 patients were retrospectively analyzed following stratification to three groups according their surgical therapy: C, complete resection, 28 patients; I, incomplete resection, 34 patients; N, no resection, 34 patients. RESULTS: Comparison of the three therapy methods concerning stage, histology and receptor levels of the primary tumor, number of metastases and the disease free interval (DFI), as well as adjuvant therapy modalities yielded no significant differences. Mean survival of group C was with 79 months (5-years-survival 80%, 10-years-survival 60%) significantly better compared to groups I and N (p < 0.00002). Mean survival of group I and N was not significantly different (15.5 and 9 months respectively). The DFI had no impact on the survival of group C, but showed a high correlation with the survival of group N (R2 = 0.81). CONCLUSIONS: Routine chest X-ray is necessary in the follow-up of breast cancer patients and if coin lesions occur, thoracic surgeon should be contacted.     

Development and treatment of pulmonary metastases in adult patients with extremity soft tissue sarcoma.

OBJECTIVE: The authors reviewed a series of adult patients with extremity soft tissue sarcoma to determine the incidence of pulmonary metastases and outcome after treatment. METHODS: Of 716 patients admitted between January 1983 and December 1990, 135 (19%) had isolated pulmonary metastases as the initial site of distant recurrence. Fifty-eight percent (78 of 135) of the patients were treated surgically, and 83% of them had their tumors completely resected. RESULTS: The median survival after complete resection was 19 months; incomplete resection, 10 months; and no operation, 8 months (p = 0.005). The 3-year survival rate after complete resection was 23%, compared with a 2% rate (1 of 57) in those treated nonsurgically (p < 0.001). Factors associated with an increased risk of pulmonary metastases included high tumor grade, tumor size greater than 5 cm, lower extremity site, and histologic type (spindle cell, tendosynovial, and extraskeletal osteosarcoma). Factors associated with complete resectability were the histologic types of spindle cell and extraskeletal osteosarcoma. CONCLUSIONS: Complete surgical resection remains the only possibility for cure from pulmonary metastases in soft tissue sarcoma; however, only 11% of the 19% of patients with an extremity sarcoma whose first distant recurrence is in the lung will be alive at 3 years, despite therapy. Complete resection and the development of more effective adjuvant treatments are imperative to improve outcome for this group of patients.     

OSTEOSARCOMA AND PULMONARY METASTASES: 15-YEAR EXPERIENCE FROM A SINGLE INSTITUTION

Background : The outcome of management in patients with osteosarcoma and pulmonary metastases at a Sydney teaching hospital was reviewed. Methods : A retrospective review was undertaken of all patients diagnosed with osteosarcoma and treated by the Bone and Soft Tissue Unit and the Medical Oncology Department, Royal Prince Alfred Hospital between 1979 and January 1995. Information was collected on demographics, tumour site, tumour histology, primary management including surgery and adjuvant therapy, and the subsequent development and management of pulmonary metastases. Results : A total of 56 patients with localized osteosarcoma was seen. Overall survival and survival following pulmonary metastases was assessed. There were 33 (59%) males and 23 (41%) females, with a median age of 27 years. Survival at 5 years, for patients with non-axial osteosarcoma was 60% (95%CI, 44–77%). Pulmonary metastases without other metastatic disease being apparent, developed in 22 patients, of whom 12 underwent surgical resection. The median disease-free interval of these latter patients was 20 months (95% CI, 8–32 months). Median survival among patients not undergoing surgical resection was 5 months from detection of metastases. Patients undergoing resection of pulmonary metastases had a median survival of 17 months following detection of pulmonary metastases (95% CI, 7–27 months). Actuarial 5-year survival was 16% (95% CI, 0–42%). Conclusions : A small proportion of patients with resectable pulmonary metastases from osteosarcoma achieve long-term disease-free survival following surgical resection. It is not possible to accurately identify these patients prospectively.     

Resection of Pulmonary Metastases from Colon and Rectal Cancer: Factors to Predict Survival Differ Regarding to the Origin of the Primary Tumor

Background

The purpose of the present study was to determine differences in prognostic factors for survival of patients with pulmonary metastases resected in curative intent from colon or rectum cancer.

Methods

Between 1980 and 2006, prognostic factors after resection of pulmonary metastases in 171 patients with primary rectum or colon tumor were evaluated. Survival of patients after surgical metastasectomy was compared with that of patients receiving standard chemotherapy by matched-pair analysis.

Results

Median survival after pulmonary resection was 35.2 months (confidence interval 27.3–43.2). One-, 3-, and 5-year survival for patients following R0 resection was 88.8, 52.1, and 32.9 % respectively. Complete metastasectomy (R0), UICC stage of the primary tumor, pleural infiltration, and hilar or mediastinal lymph node metastases are independent prognostic factors for survival. Matched-pair analysis confirmed that pulmonary metastasectomy significantly improved survival. Although no difference in survival for patients with pulmonary metastases from lower rectal compared to upper rectal or colon cancer was observed, factors to predict survival are different for patients with lower and middle rectal cancer (R0, mediastinal and/or hilar lymph nodes, gender, UICC stage) compared with patients with upper rectal or colon cancer (R0, number of metastases).

Conclusions

Our results indicate that distinct prognostic factors exist for patients with pulmonary metastases from lower rectal compared with upper rectal or colon cancer. This supports the notion that colorectal cancer should not be considered as a single-tumor entity. Metastasectomy, especially after complete resection resulted in a dramatic improvement of survival compared with patients treated with chemotherapy alone.     

Superior sulcus lung tumors: impact of local control on survival.

OBJECTIVES: Our goal was to assess patient survival and response to treatment for superior sulcus tumors treated with combined radiation therapy and surgery when possible, or with radiation alone when surgery was not possible. METHODS: Seventy-three patients were treated for primary non-small cell carcinoma of the superior pulmonary sulcus. Thirty-four patients received combined resection and irradiation. Thirty-nine patients who had extensive primary disease, distant metastases, or who were medically unfit for surgery were treated with radiation alone. Thirty-one patients (91%) assigned to the resection/irradiation group completed treatment. Combined therapy patients routinely received 40 Gy before the operation, with additional postoperative irradiation based on the surgical findings. RESULTS: Overall survival at 5 years was 19% and disease-specific survival was 20% for all patients. Overall survival and disease-specific survival at 5 years for the resection/irradiation group were 33% and 38%, respectively. Significant indicators of poor prognosis included unresected primary disease, low performance score, T4 stage, or positive node status. Eighty-two percent of the patients who received irradiation alone were treated with palliative intent. Freedom from local-regional progression, achieved initially in 66% of these patients, was associated with a median survival of 8 months. Median survival for 7 patients considered for definitive irradiation was 25 months. During the first 18 months, distant failures occurred in approximately 35% of patients in each treatment group. CONCLUSIONS: Selection of medically fit patients with resectable disease for combined surgery and aggressive radiation therapy resulted in a high likelihood of local control. Overall survival for the resection/irradiation group was significantly poorer for patients with T4 stage, nodal disease, or Horner's syndrome. Distant metastases eventually developed in 56% of patients undergoing resection. Median survival in the resection/irradiation group was significantly prolonged for those patients who could tolerate high-dose radiation treatment.     

Combined multimodal treatment for liver and lung metastasis from colorectal cancer: a new therapeutic option?

The authors analyse which therapeutic strategy to adopt on the basis of prognostic factors and staging of hepatic and pulmonary metastases from colorectal cancer. They underline the effectiveness of combined multimodal therapy in the treatment of very advanced metastatic stages. 218 patients with metastases from colorectal cancer (12 pulmonary and 206 hepatic metastases) were treated from January 1980 to October 2000. Among these patients, 159 underwent surgery (4 pulmonary and 155 hepatic resections), 16 were reoperated on for metastatic relapse, 14 with multiple metastases underwent locoregional therapy and 29, deemed unresectable initially, were treated with neoadjuvant chemo- and radiotherapy. In the operated patient group the 5-year actuarial survival rate was 22% with an operative mortality of 3.8% and a morbidity of 17.5%. The 16 patients reoperated on for metastatic relapse had a 5-year actuarial survival of 21% with an operative mortality of 6.2% and a morbidity of 15.8%. The 14 patients treated with locoregional therapy had a median survival of 6 months whereas the 29 patients treated in two different periods with combined multimodal treatment had a response rate of 59.2%. Five patients had a complete response and 4 are currently disease-free. Surgical resection is at present the best known treatment for metastatic disease. In very advanced, as yet undisseminated stages, in which there is no surgical indication for metastases a neoadjuvant treatment is proposed if the primary tumour has already been completely resected. The aim of this therapeutic strategy, called combined multimodal therapy, is to obtain the disease regression with the aid of systemic chemo- and radiotherapy and to offer a chance of re-staging the disease.     

Metastatic neuroendocrine hepatic tumors: resection improves survival

BACKGROUND: The optimal treatment for hepatic metastases from neuroendocrine tumors remains controversial because of the often indolent nature of these tumors. We sought to determine the effect of 3 major treatment modalities including medical therapy, hepatic artery embolization, and surgical resection, ablation, or both in patients with liver-only neuroendocrine metastases, with the hypothesis that surgical treatment is associated with improvement in survival. DESIGN: Retrospective study. SETTING: Tertiary care center. PATIENTS: Patients with metastatic liver-only neuroendocrine tumors were identified from hospital records. INTERVENTIONS: Patients were subdivided into those receiving medical therapy, hepatic artery embolization, or surgical management. MAIN OUTCOME MEASURES: Effect of treatment on survival and palliation of symptoms was analyzed. RESULTS: From January 1996 through May 2004, 48 patients with liver-only neuroendocrine metastases were identified (median follow-up, 20 months), including 36 carcinoid and 12 islet cell tumors. Seventeen patients were treated conservatively, which consisted of octreotide (n = 7), observation (n = 6), or systemic chemotherapy (n = 4). Hepatic artery embolization was performed in 18 patients. Thirteen patients underwent surgical therapy, including anatomical liver resection (n = 6), ablation (n = 4), or combined resection and ablation (n = 3). No difference was noted in the percentage of liver involved with tumor between the 3 groups. An association of improved survival was noted in patients treated surgically, with a 3-year survival of 83% for patients treated by surgical resection, compared with 31% in patients treated with medical therapy or embolization (P = .01). No difference in palliation of symptoms was noted among the 3 treatment groups (P = .2). CONCLUSION: In patients with liver-only neuroendocrine metastases, surgical therapy using resection, ablation, or both is associated with improved survival.     

Pulmonary metastases from colorectal cancer: 25 years of experience.

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.     

Long-term survival after aggressive resection of pulmonary metastases among children and adolescents with osteosarcoma

Purpose

Although survival without resection of pulmonary metastases from osteosarcoma is unlikely, not all surgeons agree on an aggressive surgical approach. We have taken an approach to attempt surgical resection if at all feasible regardless of number of metastases and disease-free interval (DFI). This study presents information on long-term follow-up after this aggressive approach to resection.

Methods

A single-institution retrospective cohort study of osteosarcoma patients younger than 21 years with pulmonary metastases, limited to the contemporary chemotherapeutic period (1980-2000), was conducted.

Results

In 137 patients, synchronous (23.4%) or metachronous (76.6%) pulmonary nodules were identified. The median follow-up was 2.0 years (5 days to 20.1 years) for all patients. Overall survival among patients who had pulmonary nodules was 40.2% and 22.6% at 3 and 5 years, respectively. Ninety-nine patients underwent attempted pulmonary metastasectomy (mean survival, 33.6 months; 95% confidence interval, 25.1-42.1) and 38 patients did not (mean survival, 10.1 months; 95% confidence interval, 6.5-13.6; P < .001, t test). Characteristics that were associated with an increased likelihood of 5-year overall survival after pulmonary resection were primary tumor necrosis greater than 98% after neoadjuvant chemotherapy (P < .05) and DFI before developing lung metastases more than 1 year (P < .001). No statistically significant difference in overall survival or disease-free survival was found based on the number of pulmonary metastases resected. Characteristics including primary tumor size, site, or extension; chemotherapy; early vs late metastases; unilateral vs bilateral metastases; and resection margins did not significantly affect survival.

Conclusions

Most patient and tumor characteristics commonly used by surgeons to determine utility of resection of pulmonary metastases among patients with osteosarcoma are not associated with outcome. Biology of the particular tumor (response to preoperative chemotherapy, measured by tumor necrosis percentage, and DFI), as opposed to tumor burden, appears to influence survival more significantly. We would advocate considering repeat pulmonary resection for patients with recurrent metastases from osteosarcoma.

Abstract：

Objective To study the operative techniques and the surgical results of hepatic alveolar echinococcosis. Methods Forty three patients with hepatic alveolar echinococcosis treated in our Hospital from 2000 to 2008 were studied retrospectively. They were divided into two groups: radical resection group (19 cases) and palliative resection group (24 cases). Results There were 1 surgeryrelated death, 2 patients with remote metastases, 2 patients with intrahepatic dissemination, 4 patients with recurrent jaundice and 3 patients with cholangitis in the palliative resection group. There were 3 patients with biliary fistula, 1 patient with cholangitis and 3 patients with emaciation in the radical resection group. Among the 30 patients followed-up for ≤3-≤8 years, 10 patients died in the palliative resection group and the long-term survival rate was 28.5% (4/14). One patient died from gastric cancer in the cardiac in the radical resection group and the long survival rate was 93. 7%(15/16). Conclusions The first choice of treatment for hepatic alveolar echinococcosis is radical resection. Patients could be cured by radical resection. Palliative surgery is an option for patients not manageable otherwise.     

Comparison of median sternotomy and thoracotomy for resection of pulmonary metastases in patients with adult soft-tissue sarcomas

Thoracotomy and median sternotomy have both been advocated for resection of pulmonary metastases, and the advantages of each approach remain disputed. Patients with adult soft-tissue sarcomas undergoing resection of pulmonary metastases at the National Cancer Institute were studied retrospectively to assess the results of each surgical approach. Between 1981 and 1984, 65 patients underwent 78 sternotomies (7 lobectomies, 71 wedge resections); a mean of 9.5 nodules were resected per patient (range, 1 to 61). Resection of all nodules was accomplished in 60 of 71 explorations (84%) in patients with documented metastases. Benign lesions were found during 7 explorations (9%). Thirteen of 30 patients (43%) with unilateral metastases on linear tomography (LT), 45% (9 of 20) of patients with unilateral metastases on computed tomography (CT), and 38% (5 of 13) of patients with unilateral metastases on both CT and LT had bilateral metastases at sternotomy. Survival by type of incision was compared for 84 patients who underwent complete resection of their metastases (42 by sternotomy and 42 by thoracotomy); the minimum follow-up was two years. The groups did not differ significantly with respect to prognostic variables (tumor doubling time, disease-free interval, or number of nodules resected). There was no significant difference in actuarial survival between the two groups. The complication rate was 15% for the sternotomy group and 10% for the thoracotomy group (difference not significant). There were no operative deaths. Median sternotomy results in detection of unsuspected bilateral metastases and avoidance of a second operative procedure, but it does not increase operative morbidity or mortality or compromise overall patient survival.     

腹腔镜联合胸腔镜一期切除结直肠癌肺转移的疗效及预后因素

目的：探讨腹腔镜联合胸腔镜（双镜）一期切除结直肠癌肺转移的疗效及预后相关因素。方法：回顾性分析35例结直肠癌同时肺转移患者的临床资料,其中17例进行了双镜一期手术切除（双镜手术组）,术后接受化疗;其余18例仅接受全身化疗（非手术组）,比较两组疗效并分析双镜手术患者的预后因素。结果：双镜手术组患者原发性病灶及肺转移灶均达到R0切除。双镜手术组与非手术组1、2年生存率分别为82.3%、44.4%（P=0.028）和52.3%、22.2%（P=0.001）。单因素分析显示,肺转移瘤数量（P=0.002）及纵膈淋巴结阳性（P<0.001）与患者术后生存有关,而患者的性别、年龄,原发肿瘤部位、病理类型、T分期,肺转移瘤大小、切除方式,手术前CEA水平,化疗方案均与其术后生存时间无关（均P>0.05）;多因素分析显示,肺转移瘤数量（P=0.005）、纵膈淋巴结转移（P=0.006）是患者术后的预后独立影响因素。结论：结直肠癌肺转移双镜一期手术切除可提高患者的总生存率;肺转移瘤数量及有无纵膈淋巴结转移是影响术后预后的独立因素。

     

Intentional limited pulmonary resection for peripheral T1 N0 M0 small-sized lung cancer

OBJECTIVE: The present study was undertaken to demonstrate that limited pulmonary resection for peripheral small-sized lung cancer yields outcomes not inferior to those of lobectomy. METHODS: During the 9-year period from 1992 to 2000, patients with cT1 N0 M0 peripheral non-small cell lung cancer whose maximum tumor diameter was 2 cm or less on diagnostic imaging and in whom lobectomy was determined to be feasible were treated with limited resection if the patient consented to the procedure and with lobectomy if consent to limited resection was not obtained. The survival and clinical outcome of the patients whose tumors were postoperatively staged as pT1 N0 M0 were compared between the limited resection group (n = 74) and the lobectomy group (n = 159). RESULTS: The limited resection group consisted of 60 patients treated with segmentectomy and 14 patients treated with wedge resection. Among patients followed up for a mean period of 52 months after the operation, neither the 3-year nor 5-year survivals differed significantly between the limited resection group (3-year survival, 94.0%; 5-year survival, 89.1%) and the lobectomy group (3-year survival, 97.0%; 5-year survival, 90.1%). Postoperative tumor recurrence was noted in 5 patients after limited resection and in 9 patients after lobectomy, and the difference in the incidence of postoperative recurrence between the 2 groups was not significant. CONCLUSIONS: The results of this study indicate that in patients with peripheral T1 N0 M0 non-small cell lung cancer whose maximum tumor diameter was 2 cm or less, the outcome of limited pulmonary resection is comparable with that of pulmonary lobectomy.     

Does complete resection of melanoma metastatic to solid intra-abdominal organs improve survival?

Background:Patients with distant melanoma metastases have median survivals of 4 to 8 months. Previous studies have demonstrated improved survival after complete resection of pulmonary and hollow viscus gastrointestinal metastases. We hypothesized that patients with metastatic disease to intra-abdominal solid organs might also benefit from complete surgical resection.Methods:A prospectively acquired database identified patients treated for melanoma metastatic to the liver, pancreas, spleen, adrenal glands, or a combination of these from 1971 to 2010434_2001_Article_658. The primary intervention was complete or incomplete surgical resection of intra-abdominal solid-organ metastases, and the main outcome measure was postoperative overall survival (OS). Disease-free survival (DFS) was a secondary outcome measure.Results:Sixty patients underwent adrenalectomy, hepatectomy, splenectomy, or pancreatectomy. Median OS was significantly improved after complete versus incomplete resections, but median OS after complete resection was not significantly different for single-site versus synchronous multisite metastases. The 5-year survival in the group after complete resection was 24%, whereas in the incomplete resection group, there were no 5-year survivors. Median DFS after complete resection was 15 months. Of note, the 2-year DFS after complete resection was 53% for synchronous multi-site metastases versus 26% for single-site metastases.Conclusions:In highly selected patients with melanoma metastatic to intra-abdominal solid organs, aggressive attempts at complete surgical resection may improve OS. It is important that the number of metastatic sites does not seem to affect the OS after complete resection.
