Abstract
From September 1986 to December 1989, 26 selected patients with high-grade osteosarcoma of the extremities metastatic at presentation were treated with primary chemotherapy (high doses of methotrexate, -cisplatinum and adriamycin) followed by surgery. Twenty-one cases underwent resections of the primary and metastatic tumor at the same time; owing to the disappearance of lung metastases after preoperative chemotherapy in 3 cases, only the primary tumor was operated on. Due to progression of the disease in 2 patients, no surgery was performed. Histologic examination of the resected specimen was performed to evaluate the percentage of necrosis produced by chemotherapy on the primary and metastatic tumor. After surgery, the patients received further chemotherapy with the same drugs used preoperatively plus ifosfamide and VP-16. The histologic response of the primary tumor was good (> 90 % tumor necrosis) in 25 % of the cases; in the resected metastatic nodules, 23 % had good responses. A discrepancy between the histologic response of the primary and secondary tumor was observed in only 15 % of the cases. These results seem to confirm the validity of the strategy (widely used today in the neoadjuvant treatment of non-metastatic osteosarcoma) of changing the postoperative treatment when the histologic response of the primary tumor is poor. At an average follow-up of 3.5 years, only 6 patients remained disease-free; 19 patients relapsed and 1 patient died for adriamycin cardiotoxicity. Of the 19 relapsed patients, 16 died and 3 are still alive but with uncontrolled disease. These results are much worse than those obtained in 144 cases of non-metastatic osteosarcoma of the extremities treated in the same period with the same preoperative chemotherapy (77 % with good response in the primary tumor and 78 % with continues disease-free survival). The data suggest that a very effective neoadjuvant chemotherapy for nonmetastatic osteosarcoma of the extremities gives disappointing results in osteosarcoma of the extremities which is metastatic at presentation.

Abstract
Aims and background In sarcomas of shoulder and of chest wall, latissimus dorsi muscle gives the opportunity to solve any plastic problem without recourse to free flaps. The authors report their experience in the use of latissimus dorsi pedicled flap as adjuvant procedure in the surgery of bone and soft tissue sarcoma. Methods The latissimus dorsi pedicled flap was used in seventeen patients to reconstruct composite tissue defects after sarcoma resection of the shoulder or of the chest wall. Three groups were recognized. The eight patients of Group I received the flap to close the chest cavity after a multiple rib resection performed to remove a tumor of the chest wall. In Group II four patients had the latissimus dorsi transported to reconstruct the soft tissue coverage over a proximal humerus prosthesis previously appiled after bone tumor resection. The five patients of Group III had the flap performed at the same time of the resection of a tumor arising in the shoulder area (1 bone and 4 soft tissue sarcoma). Results Two patients of the Group II presented a recurrent skin failure. A satisfactory coverage without any flap complication was provided in all the other 15 patients (88%). Conclusions Latissimus dorsi pedicled flap represents a reliable and effective technique to reconstruct large chest wall or shoulder soft tissue defects.

Abstract
The clinical courses of 193 patients with high-grade, non-metastatic osteosarcoma were reviewed to ascertain the evolution of the natural history of the disease. All patients had the primary lesion in the extremities and were treated at the Rizzoli Orthopaedic Institute between 1976 and 1982 with surgery alone (30 cases) or surgery plus adjuvant chemotherapy (163 cases). All patients were regularly followed at our Institute. One hundred and fourteen patients, of which 27 were treated with surgery alone and 87 treated with adjuvant chemotherapy, developed overt metastatic disease. No differences were found concerning the sites of the first relapse which, for approximately 90 % of cases, were lungs in both groups. However, in the group of patients treated with adjuvant chemotherapy the development of overt metastatic disease, as compared to non-adjuvant patients, was delayed with time (13 vs 8 months) and the number of metastatic nodules in the lung at first relapse was reduced. This alteration in metastatic pattern due to adjuvant chemotherapy is important because it allows surgical resection of pulmonary metastases in a larger number of patients (51 % vs 29 %).

Abstract
Primary malignant chest wall tumors are rare. The most frequent primary malignant tumor of the chest wall is chondrosarcoma, less common are primary bone tumors belonging to the Ewing Family Bone Tumors (EFBT), or even rarer are osteosarcomas. They represent a challenging clinical entities for surgeons as the treatment of choice for these neoplasms is surgical resection, excluding EFBT which are normally treated by a multidisciplinary approach. Positive margins after surgical procedure are the principal risk factor of local recurrence, therefore to perform adequate surgery a correct preoperative staging is mandatory. Imaging techniques are used for diagnosis, to determine anatomic site and extension, to perform a guided biopsy, for local and general staging, to evaluate chemotherapy response, to detect the presence of a recurrence. This article will focus on the role of imaging in guiding this often difficult surgery and the different technical possibilities adopted in our department to restore the mechanics of the thoracic cage after wide resections.

Abstract
BACKGROUND The purpose of this study was to analyze improvements in overall survival over 21 years (1982-2002), with a 5-year minimum follow-up, in the largest series from a single center ever reported. MATERIALS AND METHODS All diagnoses of high-grade osteosarcoma were included despite histological varieties, age, site and stage. Of the 1656 cases observed, 198 patients were excluded (41 consultation only, 129 low-grade varieties, and 28 lost to follow-up). Within 1458 included patients, 1032 had characteristics to be enrolled in conventional clinical trials (classic histology, age <41, localized, and extremity disease). Data are also analyzed in subgroups to define patients who benefited most. RESULTS With a median follow-up of 12 years (5-25 years), 754 patients (51.7%) are alive, of whom 613 continuously disease free. Survival at 5, 10, and 15 years is 57%, 52%, and 51%, respectively. Patients candidates for clinical trials have a survival rate of 68%, 64%, and 61%, respectively. Survival for the other patients is 30%, 25%, and 24%, respectively. Trend (joinpoint statistical analysis at real 5-year follow-up) shows a yearly statistically significant improvement of 1.31% (95% confidence interval 0.5% to 2.1%) from 51% for patients treated in 1982 to 68% for those treated in 2002. Patients who statistically benefited were those who relapsed or presented with metastatic disease at diagnosis or had axial tumors. CONCLUSIONS Despite the lack of new drugs for osteosarcoma, survival has statistically improved, especially for those patients with the worst outcome. Aggressive treatments are recommended for all patients including those with poor prognosis.

Abstract
10515 Background: After the introduction of pre-operative chemotherapy in the early 1980s, treatment of osteosarcoma had not advantages from new drugs/modalities. Aim of this work is to analyze improvements in overall survival for patients treated over 21 years (1982–2002), with a 5-year minimum follow-up, in the largest series from a single institute ever reported, including all high grade osteosarcomas, despite histology varieties, age, site, and stage. Data are also analyzed in subgroups to define patients who benefited most. Methods: All diagnoses of high grade osteosarcoma were included. Of the 1,656 consecutive cases observed, 198 patients were excluded (41 consultation only, 129 low-grade varieties and 28 lost to follow-up). Within 1,456 included patients, 1,032 had characteristics to be enrolled in conventional clinical trials (classic histology, age < 41, localized and extremity disease). Results: Considering all patients, with a median follow-up of 12 years (5–25 yrs), 754 (51.7%) are alive, 613 continuously disease-free. Survival at 5, 10, and 15 years is 57%, 52%, and 51% respectively. Patients candidates for clinical trials have a survival rate of 68%, 64%, and 61% respectively. Survival for the other patients is 30%, 25%, and 24% respectively. Jointpoint Statistical Analysis at real 5-year follow-up shows a yearly statistically significant improvement in survival of 1.31% (95% CI 0.5–2.1), from 51% for patients treated in 1982 to 68% for those treated in 2002. Within the subgroups, survival statistically improved in patients candidates to protocols, those who relapsed, or presented with metastatic disease at diagnosis, or had axial tumors. Surgery was also analyzed, with a statistical significant increase in the percentage of limb salvage procedures without an increased rate of local recurrences. Conclusions: Despite the lack of new drugs for osteosarcoma, survival has statistically improved, especially for those patients with the worst outcome. Aggressive treatments are therefore recommended for all patients including those with poor prognosis. No significant financial relationships to disclose.

Histologically verified lung metastases in benign giant cell tumours--14 cases from a single institution. INTERNATIONAL ORTHOPAEDICS 2006; 30:499-504.

Abstract
From 1975 to 1997, 649 cases of benign giant cell tumours of the bone were treated at the Istituto Rizzoli. Fourteen patients (2.1%) experienced lung metastases after a mean of 35.2 months. The time interval between the diagnosis and the appearance of the lung metastases ranged from 3 months to 11.9 years. Metastasectomy was performed in all patients. Histologically, the metastases were identical to the primary bone lesions. Two patients with unresectable multiple metastases received additional chemotherapy. After a follow-up of 70 months (range: 8.2 to 185 months), all patients are alive. Ten patients showed no evidence of disease, one of these after a second resection of metastases, and four patients presented stable disease with multiple lung metastases. Local recurrence of the bone lesion occurred in seven patients before or simultaneously to the metastases. In contrast to previous reports, we could not detect a predominance of the distal radius, but all of the patients had a stage III tumour according to the Enneking criteria of benign lesions. We conclude that even metastatic benign giant cell tumours have an excellent prognosis after adequate resection. No prognostic factors despite high-grade lesions were detectable.

Abstract
The addition of chemotherapy and radiotherapy to local treatment for Ewing's sarcoma of bone (ES) significantly bettered its prognosis. Nonetheless, although with no signs of local recurrence some patients still relapse with lung metastases. These patients are generally treated with non-surgical procedures. The few reports in literature on surgical resection of metachronous pulmonary metastases do not allow any conclusions. This study aims to report the results achieved in 24 Ewing's sarcoma patients who relapsed only with lung metastases, and no local recurrence, treated with surgery at the authors' institution.

Abstract
BACKGROUND Many papers have reported the results achieved with combined therapy for Ewing's tumors, but little is known about the treatment and outcome of those 30-40% of patients who relapse. PATIENTS AND METHODS In a retrospective study, we evaluated 195 patients with Ewing's tumors treated at our institution from 1979 to 1997 with chemotherapy, radiotherapy, surgery or combined therapies after recurrence. RESULTS A second complete remission was achieved in only 26 patients (13.3%); 12 relapsed again and died of the tumor. The 5-year post-relapse event-free survival and overall survival were 9.7% and 13.8%, respectively; both of which were significantly better for patients who had relapsed >/=2 years after the beginning of the first treatment (14.3% versus 2.5%; P <0.001) and for patients who relapsed with only lung metastases (14.5% versus 0.9%; P <0.0005). In terms of treatment, patients treated with surgery or radiotherapy, alone or in combination with chemotherapy, had better survival rates than patients treated with chemotherapy alone (15.4% versus 0.9%; P <0.0001). CONCLUSIONS The outcome of Ewing's tumor patients who relapse after combined treatment is very poor. However, these patients may be divided into two groups: those that can be cured with traditional treatments (late relapse and/or only lung metastases), and a second group of patients (early relapses with metastases in lungs and/or other sites) who gain no benefit from traditional therapies. For the latter group, multicenter studies are needed to evaluate new strategies of treatment.

Abstract
BACKGROUND Effective adjuvant or neoadjuvant regimens of chemotherapy have dramatically improved the prognosis of patients with high-grade osteosarcoma of the extremity, localized at diagnosis. Currently, little is known about patients with metastatic disease at presentation. PATIENTS AND METHODS From May 1995 to May 2000, 57 patients with osteosarcoma of the extremity, metastatic at presentation, were treated according to the following scheme: primary chemotherapy, restaging, simultaneous resection of primary tumor and metastatic lesions, and maintenance chemotherapy. RESULTS Thirty-five patients achieved remission. At a follow-up ranging from 2 to 7 years, seven remained continuously free of disease, one died of chemotherapy-related toxicity and 27 patients relapsed. Twenty-one of the 22 patients who never achieved remission died as a result of the tumor, as well as 20 of the 27 who achieved remission but then relapsed. Of the remaining seven relapsing patients, six are alive with uncontrolled disease, while one is alive and free of disease 24 months after the last post-relapse treatment. Two-year event-free survival (EFS) and overall survival (OS) were 21% and 55%, respectively. These results are significantly poorer than those achieved in 128 contemporary patients with non-metastatic disease at presentation, treated with the same chemotherapy protocol (2-year EFS and OS of 75% and 94%, respectively). CONCLUSIONS The results of our study confirm that the prognosis of patients with osteosarcoma of the extremity, metastatic at presentation, remains poor, despite the use of aggressive treatments.

Abstract
Surgery used to treat chest wall sarcomas requires preoperative evaluation in order to document their margins, and to reveal any nodules of recurrence. Because of its considerable sensitivity and specificity ultrasound was associated with routine imaging techniques. The results obtained are useful in defining superficial and lateral tumor margins, but particularly in determining micro-nodules of recurrence which would otherwise go unrecognized. Based on the data obtained using routine methods of diagnosis and ultrasound, we submitted patients to excision that each and every time proved to be wide on histological examination. A particular surgical method was used for reconstruction, involving a polypropylene mesh fixed to one or two mouldable plates. This method exploits the elasticity of polypropylene, which is indispensable for the correct respiratory dynamics of the rib cage, thus avoiding paradoxical or harmful movement. Oncological and functional results were satisfactory.

A 27-year-old woman with a giant cell tumor of the rib with a cystic-hemorrhagic appearance underwent surgery consisting of en bloc resection and reconstruction of the thoracic wall with Marlex mesh, reinforced with two titanium plates. When possible this type of tumor requires resection, instead of radiotherapy, since the majority of cases of malignant transformation are linked to prior radiation therapy.

Abstract
With the intention of starting an international protocol between Italy and Scandinavia on neoadjuvant treatment of extremity osteosarcoma using the four active drugs at maximum doses (doxorubicin 75 mg/m2 pre-operatively, and 90 mg/m2 post-operatively, cisplatin 120 mg/m2, methotrexate 12 g/m2, and ifosfamide 15 g/m2), a single center (the Rizzoli institute) performed a pilot study to closely monitor toxicity, safety, and tumor necrosis. Only 7 patients (10%) had a reduced number of the scheduled cycles. A total of 1,050 of the expected 1,076 cycles (98%) were administered. Delays and dose reduction were minimal, leading to a mean received dose intensity of 89%. Limb salvage surgery was performed in 59 cases (87%), with 6 amputations and 3 rotation plasties. Chemotherapy-induced necrosis higher than 95% was observed in 38 patients (56%). Eleven patients had total necrosis (16%). At a median follow-up of 60 months (range 50-65 months), 53 patients (73%) were continuously disease-free. Six of the relapsed patients were rescued with further treatments leading to an overall survival of 87%. Hematological toxicity was remarkable despite the use of G-CSF and hospitalization due to febrile neutropenia occurred in 25 patients (37%). Platelet transfusions were required in 77 of the 194 episodes of grade 4 thrombocytopenia, but no case of major bleeding was observed. Red blood cell transfusions were necessary in all patients (in 15 cases perioperatively only). Non-hematological toxicity comprised grade 1-2 nephrotoxicity in 3 cases, CNS toxicity in 2 cases, and dilata- tive cardiopathy leading to heart transplantation in 1 case. In conclusion, the pilot study was feasible in the vast majority of cases with toxicity not superior to that of the previous protocols where chemotherapy was given in lower doses. The rate of limb salvage procedures, event-free survival and overall survival seemed to be higher than in previous protocols. On the basis of this study, in March 1997 the Italian and Scandinavian Sarcoma Groups started a new protocol for osteosarcoma of the extremities.

Abstract
Over the last 20 years at the Rizzoli Orthopaedic Institute in Bologna 20 cases of chondrosarcoma (CS) of the thoracic wall (14 males, 6 females, mean age 49 years) have been submitted to surgery. Localization was costal in 11 cases, costosternal in 3, sternal in 3, costovertebral in 3. The most frequent histological variety was central with 15 observations. All of the cases were treated surgically. Exeresis was wide in 14 cases, marginal in 6. Reconstruction of the thoracic wall took place either by direct suturing or (14 cases) using prosthetic materials (Marlex mesh, 1 or 2 shapeable metal plates). Of the 20 cases treated, 16 patients are still alive (80%) with a mean survival rate of 33.5 months and a mean reduction in the postoperative ventilative index of function of less than 10%. The results obtained lead us to believe that surgical treatment involving wide exeresis is adequate, and the reconstruction method using Marlex mesh and metal plates is reliable.

Abstract
This retrospective study examined 10 patients with osteoid osteoma and 11 patients with osteoblastoma localized in the sacrococcyx. In the sacrum, the diagnosis was delayed compared to other sites. Curettage through a posterior approach is the treatment of choice. Radiotherapy as well as embolization of feeding arteries may be used for the most aggressive lesions. Prognosis is generally good with a low incidence of local recurrence (<10%).

Abstract
From January 1993 to March 1995, 162 patients with osteosarcoma of extremities were treated according to the IOR/OS-4 protocol. 133 patients had localised disease, while 29 had metastases at diagnosis. These last patients were simultaneously operated upon for their primary and metastatic lesions. Chemotherapy consisted preoperatively of two cycles of high dose methotrexate (HDMTX) and one cycle each of cisplatin (CDP)-doxorubicin (ADM), CDP/ifosfamide (IFO) and IFO/ADM. After surgery, patients were treated with the aforementioned drugs used as single agents. The mean follow-up of all patients was 6.5 years (5.5-8 years). Surgery was a limb salvage in 94% of cases, and the 5-year event-free survival (EFS) and overall survival (OS) rates were 56 and 71% for patients with localised disease, and 17 and 24% for patients with metastases at diagnosis. These results did not differ from those achieved in our previous study (IOR/OS-3) in which IFO was used only postoperatively in poor responders.

Abstract
BACKGROUND The purpose is to evaluate the accuracy of computed tomography (CT) in the pulmonary staging of osteosarcoma. PATIENTS AND METHODS Fifty-one patients presenting with osteosarcoma and at initial CT considered metastatic to the chest had lung surgery. Two teams of two senior radiologists independently reviewed all CT examinations. Their results were compared to the histological studies. RESULTS One hundred nineteen CT's were reviewed. The 2 teams found 247 and 268 nodules on the initial. and 143 and 146 nodules on the preoperative CT. Histological studies confirmed metastatic nodules in 29 patients. Two hundred four nodules were excised and studied. One hundred nine were metastases. The 22 patients without metastases had 53 negative nodules removed. In the 29 patients with metastases, 151 nodules were removed, and 42 were non-metastatic. The positive predictive value was 53% with regard to 'nodules', and 57% with regard to 'patients'. Only 4 out of 13 patients with one nodule at surgery were metastatic, but all patients with more than 7 nodules were metastatic. The 46 cases with several available CT's, showed that no change in the number of nodules was more frequent in benign lesions. Other criteria revealed no significant difference. CONCLUSION CT positive predictive value is limited, but as surgery is the only way to cure metastatic patients, CT will still be used as the reference technique until a more specific approach can be found.

Abstract
Between January 1995 and December 1999, 11 patients with synchronous multifocal osteosarcoma (SMO) received neoadjuvant treatment with high-dose methotrexate, cisplatinum, Adriamycin, and ifosfamide. After primary chemotherapy in 4 patients who had only two bone localizations, it was possible to treat all tumor foci locally. The remaining patients, with more than three bones involved, were treated surgically only in 3 cases at the primary site, while secondary lesions did not receive any treatment. The final results of our study were disappointing. All patients died of the tumor 6 to 24 months after the beginning of treatment (mean 11.9 months). Nevertheless, the survival time of the 4 patients with locally treated lesions was significantly longer than the one of 7 patients in whom the secondary lesions were not locally treated (18.2 vs 9.1 months; P<0.008). It should be noted that those patients simultaneously operated on two sites, the response to chemotherapy of "primary" and "secondary" lesions was always similar. This homogeneity supports the thesis that in synchronous multifocal osteosarcoma the tumors are not multicentric in origin but represent bone-to-bone metastases from a monocentric tumor.

Abstract
It is often difficult to identify the characteristics of soft-tissue tumors of the chest wall. This paper describes the peculiarities of elastofibroma dorsi, a rare pseudotumor of this site, to exclude many dangerous misconceptions. During the period between 1987 and 1997, we treated nine patients with elastofibroma dorsi. In six patients, the lesion was unilateral and in three it was bilateral. All these lesions were excised and no evidence of local recurrence or shoulder disability was observed at the last clinical evaluation. Elastofibroma dorsi is a rare, slow-growing, pseudotumoral lesion of the soft tissues of the chest wall with a peculiar radiographic and histologic pattern.

Abstract
We report on the clinical course and outcome of 28 patients, treated at The Istituti Ortopedici Rizzoli between 1995 and 1997 for osteosarcoma of the extremities metastatic to the lung at presentation. The treatment for these patients was the following: primary chemotherapy with cisplatin, adriamycin and high dose of methotrexate and ifosfamide followed by simultaneous resection of primary and metastatic lesions (when feasible), and further chemotherapy. After primary chemotherapy, lung metastases disappeared in 6 patients, whereas metastases in 3 remained surgically unresectable. These 9 patients received surgical treatment of the primary tumor only. In the remaining 19 patients, after chemotherapy, a simultaneous resection of the primary and metastatic tumor was performed. The resection of metastatic lesions was complete in 18 cases and incomplete in one. Three of the 4 patients who did not achieve a tumor-free status died in a few months and one is still alive with uncontrolled disease. With a median follow-up of 32 months (19-43) of the 24 patients who achieved remission, 12 (55%) remained continuously free of disease, 11 relapsed with new metastases and 1 died of chemotherapy-related toxicity. The 2-year DFS and OS were 36% and 53% respectively. These results are much worse than those achieved in 114 contemporary patients with localised disease (2-year DFS: 81%) treated in the same period and they are superimposible to the results achieved in 23 patients previously treated with the same protocol, but with standard dose of ifosfamide (2-year DFS: 32%). However, it must be underlined that, as regards prognosis, patients with metastatic disease at presentation are a hetero-geneous group. The DFS was significantly higher for patients with only one or two metastatic lesions than for patients with 3 or more lesions (2 year DFS: 78% vs. 28%). In 12 of the 19 patients who had a complete simultaneous resection of the primary and metastatic tumor, a strong correlation between the degree of necrosis of the primary and metastatic lesions was found. We conclude that in patients with osteosarcoma of the extremity with lung metastases at presentation: a) the combination of aggressive chemotherapy with simultaneous resection of primary and metastatic tumors works very well only for those patients who present with one or two metastatic nodules whereas for patients with 3 or more pulmonary metastases the prognosis is very poor; b) within the 4-drug regimen used in this study, the increment of ifosfamide dose from 10 g/m2 to 15 g/m2 for cycle does not improve prognosis; c) the strong correlation found between the histologic response of the primary tumor and metastases supports the strategy, largely used nowadays in the neoadjuvant treatment of osteosarcoma, of tailoring postoperative chemo-therapy on the basis of the primary tumor histologic response to preoperative chemotherapy.

Abstract
Two hundred and six patients were operated for lung metastases from osteosarcoma over a period of 7 years. The operative mortality was 0.3%. The actuarial survival for the overall population was 78% at one year. 50% at two years, 40% at three years and 34% at five years. The most significant prognostic factors (p < 0.01) were the number of metastases, the duration of the free interval and the degree of differentiation. Sex, age, site and type of resection of osteosarcoma or the metastases did not have any influence on prognosis. Surgical resection of lung metastases currently constitutes an essential part of the multidisciplinary management of osteosarcoma.

Abstract
BACKGROUND The different histological varieties of anal cancer due to the presence of different histogenesis tissue can be anatomically distinguished from anal canal tumours by their growth in a periorificial or marginal site. The first appearance of symptoms are common to usual non-tumoral pathologies, but can be ascertained at an early stage using biopsy. Anal cancer can be treated with surgery, conservative or radical treatment, radiotherapy alone and radiochemotherapy with possible surgery. METHODS Based on the results obtained by radical surgical exeresis due to the frequent spread of tumours to the pelvis and the possibility of metastases in the cava and portal vein, current therapeutic possibilities were analysed in 101 patients with anal cancer undergoing abdominal-perineal surgery. The priority of radiochemotherapy was underlined, reserving the faculty of surgical treatment for cases of large tumours with insufficient penetration. RESULTS The choice of therapy should be modulated according to its histology, tumour site, increase and grading. Only surgery can ensure long-term results similar to those obtained using surgical treatment of rectal cancer. CONCLUSIONS For the best results the authors recommend a therapeutic approach which involves some methods used for an early diagnosis.

Abstract
BACKGROUND AND AIM The authors report the findings of a retrospective study made of 150 cases of bronchogenic non-small-cell carcinoma at stage IIIA. METHODS Of the 150 patients treated 130 were male and 20 female. The mean age of the population examined was 55, with a minimum of 28 and maximum of 76. The techniques of exeresis used were pneumonectomy in 70 cases (33.3%) (simple in 50 cases--33.3% and intrapericardial ligation of pulmonary vessels in 20--13.3%), lobectomy in 61 cases (40.6%), lobectomy with associated atypical resection in 9 cases (6%), atypical resection in 6 patients (4%) and bilobectomy in 4 (2.6%). RESULTS The 5-year survival rate was 16.9%. It was also found that the 5-year survival rate was 20.7% higher for epidermoid carcinoma compared to other histiotypes. The technique used also influenced survival and subjects undergoing pneumonectomy presented a 5-year survival of 29.7% compared to 26.8% for lobectomies associated with atypical resection. CONCLUSION Surgery of bronchogenic carcinoma at stage IIIA has not obtained promising results in terms of survival. However, no other alternative treatment permits an average 5-year survival rate of 15% to be achieved.

Abstract
Between September 1986 and September 1991, 44 patients with lung metastases originating from an osteosarcoma of an extremity were treated with: primary chemotherapy, simultaneous resection of primary and metastatic lesions (when feasible), and then further chemotherapy. After primary chemotherapy, lung metastases disappeared in 5 patients, whereas in 11 patients they remained surgically unresectable. All 16 patients received local treatment of the primary tumor only. In the remaining 28 patients simultaneous surgical treatment of the primary and the metastatic tumor was performed. The removal of metastatic lesions was complete in 25 and incomplete in 3 patients. With a median follow-up of 8 years (5.5-10.8) all 14 patients who never achieved a tumor-free status died. Of the 30 patients who achieved remission 5 (17%) remained continuously free of disease and 25 developed new metastases, associated with local recurrence in 4 cases. The 5-year overall survival for all 44 patients of the study was 14%, and the 5-year disease-free survival for the 30 patients who reached remission was 17%. These results are significantly worse than those achieved with the same chemotherapy protocol in 144 contemporary patients with localized disease at presentation (73% disease-free and 79% overall survival). We conclude that, despite aggressive chemotherapy which is successful in patients with localized disease, the prognosis remains very poor for patients with osteosarcoma of the extremities with lung metastases at presentation, and justifies the use of novel therapies.

Abstract
The authors describe neurologic deficit (sensory, motor, and sphincteral) resulting from sacrifice of the sacral nerve roots removed during resection of the sacrum. The anatomical and functional bases of sphincteral continence and the amount of neurologic deficit are discussed based on level of sacral resection. A large review of the literature on the subject is reported and discussed. The authors emphasize how the neurophysiological bases of sphincteral continence (rectum and bladder) and of sexual ability are still not well known, and how the literature reveals disagreement on the subject. A score system is proposed to evaluate neurologic deficit. The clinical model of neurologic deficit caused by resection of the sacrum may be extended to an evaluation of post-traumatic deficit.

Abstract
BACKGROUND Improvements in preoperative staging as well as in chemotherapeutic regimens have made limb-salvage surgery a reliable modality of treatment for high-grade osteosarcomas of the extremities, with local recurrences in most series of less than 10% after this type of surgery. The quality of surgical margins and local response to preoperative chemotherapy are known to be the most significant factors in recurrence [1, 8-10, 12], and complications related to the biopsy procedure may also be a significant factor. The study reported here comprised a histopathological analysis of our recurrent cases as part of an effort to identify the impact of each of the factors cited above. MATERIALS AND METHODS Five hundred fourteen cases of high-grade, non-multicentric osteosarcoma of the extremities were treated at the Istituto Ortopedico Rizzoli between March 1983 and August 1991. In this study we analyzed 23 cases of local recurrence in patients with classic osteosarcoma who underwent limb-salvage procedures. RESULTS In 15 cases we found correlation between the site of local recurrence and the site where the margins were less than wide. In five cases the recurrence was secondary to complications of the biopsy procedure (hematoma, delayed healing). In one case we suspect a previously undetected skip lesion. In the remaining two cases no clear explanation was found for the recurrence. There was also a statistically significant difference in the time of appearance of recurrences related to the tumor response to chemotherapy. CONCLUSIONS For only two cases of recurrence was there no clear explanation. In one we suspect an undetected skip metastasis, and in the other there were certain factors which may have increased its risk of recurrence (non diagnostic trochar biopsy followed by an incisional biopsy, fair tumor necrosis, recurrence in a 'problem' anatomical site, i.e., the popliteal space). In the remaining cases the following factors were found to be directly related to the development of a local recurrence: a) the quality of the surgical margins, b) site of the biopsy as well as complications related to the biopsy procedure, c) local response to preoperative chemotherapy.

Abstract
BACKGROUND Most of the studies of the treatment of non-metastatic osteosarcoma of the extremity have reported results in terms of probability of survival up to five years with a minimum follow-up of less than two to three years. Definition of reliable indicators of prognosis and predictive factors for survival require mature data derived from a long-term survival analysis. PATIENTS AND METHODS A review of 127 patients with non-metastatic osteosarcoma of the extremity, treated between March 1983 and June 1986, was performed. The treatment protocol consisted of primary chemotherapy with MTX (randomization to high vs. moderate dosages) and CDP followed by surgery. Postoperatively, patients with < 60% tumor necrosis received ADM and BCD; those with tumor necrosis > or = 60% < 90% (Fair Responders FR) were given MTX, CDP and ADM. Up to January 1984, patients with tumor necrosis > 90% received MTX and CDP only, and after then they were given the same treatment as for FR. A multivariate analysis to test predictive factors for survival was performed. RESULTS With a median follow-up of 134 months (range 114-153), the 12-year DFS was 46%. A good histologic response, an LDH baseline value within the normal range, and the use of high-dose MTX were positive predictive factors for DFS. With a median time of observation for survivors of 130 months, the 12-year overall survival was 53%. None of the patients who relapsed with local or distant recurrences other than lung metastasis are now alive. Patients with a relapse-free interval longer than 24 months had a significantly better post-relapse survival than those with a shorter relapse-free interval (40% vs. 7%; P = 0.0159). All of the patients who were not surgically treated had disease progression and died within 40 months after the first recurrence. The surgically-treated patients had a 30% post-relapse survival probability. CONCLUSIONS In non-metastatic osteosarcoma of the extremity, chemotherapy-induced tumor necrosis, the baseline LDH serum value and the use of HDMTX are significant predictive factors for DFS. The relapse-free interval and the possibility of metastasectomy are significant factors conditioning the post-relapse survival.

Abstract
BACKGROUND In the past 20 years, it has been demonstrated that the combination of surgery and chemotherapy improves the prognosis for patients with osteosarcoma of the extremity without detectable metastases at presentation. By contrast, the efficacy of chemotherapy coupled with aggressive surgery has not yet been well established for patients with metastatic disease at diagnosis. The current study evaluates the efficacy of chemotherapy associated with simultaneous surgery of primary and metastatic lesions in patients presenting with osteosarcoma of the extremity with lung metastases. METHODS Patients with lung metastases originating from an osteosarcoma of the extremity received chemotherapy (high dose methotrexate, cisplatin, doxorubicin, and ifosfamide) followed by simultaneous resection of primary and metastatic lesions and additional chemotherapy. RESULTS Between January 1993 and June 1995, 23 patients entered the study. After primary chemotherapy, lung metastases disappeared in three patients, whereas in four patients they remained surgically unresectable. All seven patients received surgical treatment of the primary tumor only. In the remaining 16 patients, a simultaneous resection of the primary and metastatic tumors was performed after chemotherapy. The resection of metastatic lesions resulted in a complete remission in 15 patients and an incomplete remission in 1 patient. All five patients who never achieved tumor free status died within a few months. Of the 18 patients who achieved radiologic remission at a 30-month follow-up (range, 14-50 months), 10 (55.5%) remained continuously free of disease, 7 relapsed with new metastases, and 1 died of toxicity. In 13 of the 18 patients who underwent a complete simultaneous resection of the primary and the metastatic lesions, or whose pulmonary metastases disappeared after chemotherapy, a strong correlation was found between degree of necrosis of the primary tumor and of the metastatic tumor. CONCLUSIONS In patients presenting with osteosarcoma of the extremity with lung metastases, the combination of aggressive chemotherapy with simultaneous resection of the primary and metastatic lesions improves traditionally negative outcomes. The strong correlation found between the histologic response of the primary and metastatic tumors supports the strategy, largely used currently in the neoadjuvant treatment of osteosarcoma, of tailoring postoperative chemotherapy on the basis of the histologic response of the primary tumor to preoperative chemotherapy.

Abstract
BACKGROUND Multifocal osteosarcoma is a rare type of tumor which is always excluded from therapy trials and is therefore rarely investigated for prognosis and treatment. PATIENTS AND METHODS Twelve patients with synchronous multifocal osteosarcoma underwent neoadjuvant chemotherapy and, when feasible, simultaneous resection of involved bones. RESULTS Four patients were unsuitable for resection and died 5-13 months (average 9 months) later. In eight patients all lesions were resected simultaneously. Four patients are disease-free at 15, 20, 24, and 60 months (average 29 months), and four relapsed and died at 12, 24, 30 and 36 months (average 30.5 months). CONCLUSIONS Chemotherapy associated with aggressive surgery may be useful. The histological response of different lesions in the same patient are strongly correlated, confirming that synchronous multifocal osteosarcoma is not originally multicentric but unicentric with bone metastases.

Abstract
The authors analysed the patterns of recurrence of osteosarcoma of the extremities treated between 1959 and 1989 either with surgery alone (1959-71) or with combined surgery and adjuvant (1972-82) or neoadjuvant chemotherapy (1983-89). In a total of 452 patients with recurrent osteosarcoma, the initial site of metastasis was the lung in 88% of cases independently of the type of treatment received. The mean period of onset of pulmonary metastasis differed according to the type of treatment performed: 8 months for patients treated with surgery alone; 15.9 months for those treated with adjuvant chemotherapy and 20.3 months for patients treated with neoadjuvant chemotherapy. The incidence of metastases appearing within 12 months of FU was 87%, 56% and 21% respectively. In a most recent and effective neoadjuvant protocol (66% DFS), the incidence of recurrence owing to pulmonary metastasis during the first year of FU was 2% and as much as 75% of all recurrences were concentrated in the following 18 months. Surgery for pulmonary metastasis in patients undergoing chemotherapy was performed in 54 cases with secondary healing in 14 (26%). On the basis of these results the authors suggest a scheme of radiological follow-up for patients with osteosarcoma of the extremities treated with neoadjuvant chemotherapy with intensified controls (every 2 months) during the period with the highest risk of recurrence (13-20 months) and four-monthly controls during the first year and after 31 months of FU. In order to increase the efficacy of FU controls during the high-risk period, the a. propose using CT controls instead of chest X-rays at months 14, 20 and 26.

Abstract
In 551 patients with osteosarcoma of the extremities treated between 1980 and 1991 in our Institution with surgery only (35 cases), surgery combined with adjuvant chemotherapy (147 cases) or neoadjuvant chemotherapy (369 cases) the relapse patterns were analyzed. Adjuvant chemotherapy was performed according to 2 different protocols and neoadjuvant chemotherapy according to 3 different protocols successively activated. In the 252 patients who relapsed, the interval between initial treatment and first relapse was significantly longer in the group treated with adjuvant and neoadjuvant chemotherapy (18.1 and 21.3 mo) than in the group treated with surgery only (5.4 mo). For patients treated with neoadjuvant chemotherapy, a longer interval was seen in the most effective regimen of neoadjuvant chemotherapy (25 mo). No significant differences were seen among the 3 groups, according to the site of first metastasis, although in patients treated with the most effective neoadjuvant regimen there was a higher incidence of bone metastasis. In patients who relapsed with pulmonary metastases the average number of nodules seen by standard X-rays, as well as CT scans, was significantly higher in patients treated with surgery only (3.6) than in patients treated with adjuvant or neoadjuvant chemotherapy (2.5 and 2.6 nodules). We conclude that these changes in metastatic pattern in patients treated with adjuvant and neoadjuvant chemotherapy are important, because they may encourage the use of salvage therapy with thoracotomy in a larger number of patients. Prolongation of time relapsed after more effective regimens of adjuvant and neoadjuvant chemotherapy should be considered when evaluating the preliminary results of new chemotherapy protocols.

Abstract
55 patients with Ewing's sarcoma of bone, treated at our Institution with adjuvant or neoadjuvant chemotherapy between 1972 and 1990, relapsed with pulmonary metastases alone. 12 of these patients--selected according to their long disease-free interval before relapse, monolaterality of the lesions, small numbers of metastatic nodules, resectability and refusal to undergo further chemotherapic treatments--were treated with surgical resection of the metastatic lesions and with no additional radio- or chemotherapy. At a follow-up ranging between 3 and 14 years (mean 9 years), 5 of these 12 patients (42%), were continuously free of disease, whereas the remaining 7 patients died with uncontrolled disease 12-39 months (mean 22 months) after thoracotomy. These results seem to indicate that an aggressive surgical approach should be considered for a selected group of Ewing's sarcoma patients who relapse with only lung metastases.

Abstract
Studies on the use of revertants to overcome MDR have aroused a great interest even if they failed to prove their actual usefulness. A case of 10 years and 6 months old boy is described. He suffered from osteoblastic osteosarcoma and underwent chemotherapy following CNR-NEO3 protocol, wide surgical resection and postoperative chemotherapy. Nineteen months after diagnosis he underwent the removal of a little subpleural nodule in the right lung. Forty-five days later, in the same site, a large local metastasis was observed together with many others secondaries localizations spred in both lungs. Because of the rapid evolution they were considered not suitable for surgical treatment. A cyclosporine and verapamil treatment in association with adryamicin and etoposide was begun with the aim overcoming multidrug resistance. Five treatments were provided. ECG monitoring during verapamil infusion did not show any trouble; mielotoxicity was mild, with no need of transfusions. A lung CT scan at the end of the therapy demonstrated an important decrease of the subpleural metastasis and the vanishing of lung nodules. Another surgical intervention was provided together with 2 postoperative chemotherapy treatments. Twenty-six months later no sign of the disease was observed. Association of verapamil and cyclosporine with chemotherapy allowed to get a good clinical response with a very low toxicity, in a critical situation in which chemotherapy alone did not seem to offer any real possibility.

Abstract
Surgery for pulmonary metastases is an accepted method of treatment for many kinds of malignant neoplasms, because of favorable results in five-year and ten-year survival. At present several technical aspects are being debate (operative indications, method of thoracic access, procedure of lung resection, approach of bilateral lesions), with the aim of improving the number of patients undergoing radical excision of all pulmonary metastatic foci. The present paper summarizes a recent experience (1989-1992) in the treatment of pulmonary metastases in 55 patients, with special reference to tactical and technical problems related to metastasectomies. The primary tumor was an osteogenic sarcoma in 28 cases (51%), other musculoskeletal and soft tissue sarcoma in 20 (36%), and epithelial neoplasms in 7 (13%). In 47 patients (85%) the discovery of pulmonary metastases was metachronous regarding primary malignancy, with a range of between 3 months and 17 years; in the other 8, lung disease was simultaneous with diagnosis of neoplasm. All patients underwent preoperative standard chest X-ray, thoracic computerized tomography and lung function assessment; the radical control of primary neoplasm and the absence of any extrapulmonary metastases were required for thoracotomy. Pulmonary nodules were single in 21 patients (38%), multiple ipsilateral in 16 (29) and bilateral in 18 (33%). The thoracic approach was a muscle-sparing thoracotomy (axillary vertical thoracotomy) in 51 patients, other thoracotomies in 3 and a median sternotomy in 1 patient. The operative procedures were 19 single wedge resections (35%), 27 multiple wedge resections (49%), 1 lobectomy (2%), 1 lingulectomy (2%) and finally 7 exploratory thoracotomies (12%) for different reasons. In patients with bilateral disease, a bilateral synchronous thoracotomy and multiple wedge resection was performed 13 times, while staged thoracotomy was necessary in 2 and a median sternotomy was preferred in 1 case; 2 patients received a monolateral axillary exploratory thoracotomy. A total of 186 lung nodules were excised, but only in 161 (86%) the histologic examination confirm the metastasis. There was no operative mortality and the postoperative complications were few. Based on this experience, the authors believe that every neoplastic patient with pulmonary metastases, certain or suspected, should be considered for thoracotomy, since metastasectomy is a very safe procedure today.(ABSTRACT TRUNCATED AT 400 WORDS)

The surgical treatment of spondylolisthesis. LA CHIRURGIA DEGLI ORGANI DI MOVIMENTO 1994; 79:85-91. [PMID: 8076482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 01/28/2023]
Abstract
The authors report the results obtained in 244 patients submitted to anterior interbody fusion. The method involves preoperative reduction in plaster (when necessary) and anterior surgical stabilization, facilitated by improvement in the anatomical and biomechanical conditions obtained with reduction. This method obtained excellent results in 85% of the cases, with fusion and absence of symptoms, and good results in 10% of the cases, with occasional symptoms and/or fibrous. Results were unsatisfactory in 5% of the cases because of residual radiculopathy (4 cases), non-union of the fusion (3 cases), retrograde ejaculation (2 cases), loosening of the graft (1 case) or unthreading of a screw (1 case). It is our opinion that anterior interbody fusion is the best surgical method for the stabilization of Meyerding grades III, IV and V spondylolisthesis. Posterolateral fusion is used to treat some cases with slippage equal to less than 25% (grade I) and cases where more than one level is involved.

Abstract
The analysis of 265 selected cases of right colon cancer treated over a long period of time allows a number of points to be raised. Attention is drawn to the lack of progress made in diagnostic techniques, but this is thought to be due primarily to the vagueness of symptoms and their scarse investigation rather than to limits imposed by instrumental techniques. Moreover, no real benefit would be produced by a more aggressive approach using visceral or lymphatic exeresis. An earlier diagnosis of tumours due to differentiation, slow growth and rare association with adenoma should allow more encouraging results to be achieved.

Abstract
Pulmonary hamartoma is a rare benign tumor often found by chance. Only in 10% of cases are some calcifications like "pop corn". Fibrobroncho-scopy is help only in endobronchial forms; they don't reach 10% of cases. Computed Tomography and transparietal biopsy can be diagnostic. In the uncertain cases and in presence of symptoms, thoracotomy with exeresis of tumor is justified.

Abstract
Eight cases of Meckel's diverticulum observed by the authors are reported. Different investigative methods, clinical and surgical aspects are discussed. Even asymptomatic Meckel's diverticulum discovered incidentally at surgery should usually be removed.

Abstract
From September 1986 to September 1990 35 patients affected by osteosarcoma of the extremities with synchronous metastasis were treated with two cycles of high-dose methotrexate IV, cisplatin IA and adriamycin IV followed, in 22, by simultaneous resection of the primary and metastatic tumor. Six patients progressed and were not operated on, 7 patients with complete response of pulmonary nodules underwent surgical resection of the primary lesion. A complete histological examination of the resected specimens was always performed to evaluate the percentage of necrosis produced by chemotherapy on both the primary and metastatic tumor. After surgery the patients received 3 more cycles of the same drugs as used preoperatively plus ifosfamide. The histological response of the primary tumour was "good" (90% or more tumour necrosis) in 8 patients (27%) and "poor" (less than 90% of tumour necrosis) in 21 (73%) while in the 75 metastatic nodules the resulting necrosis was good in 18 (24%) and poor in 57 (74%). A good correlation between the histological response in the primary and metastatic tumour was observed. At an average follow-up of 30 months (R 12-60), 13 patients are alive, 10 disease-free, and 3 with uncontrolled disease. This data suggest that prognosis of osteosarcoma of the extremities with synchronous metastases remains poor even with a very aggressive treatment. Our results also seem to confirm the validity of the present strategy in the treatment of non metastatic osteosarcoma: to introduce new drugs postoperatively in patients poor responder can allows a better treatment of microscopic disease and can improve the prognosis for these patients.

Abstract
From September 1986 to September 1989 11 patients affected by osteosarcoma of the extremities with synchronous metastases were treated with two cycles of high-dose methotrexate i.v., cisplatin i.a. and adriamycin i.v. followed by simultaneous resection of the primary and metastatic tumor. A complete histological examination of the resected specimens was always performed to evaluate the percentage of necrosis produced by chemotherapy on both the primary and metastatic tumor. After surgery the patients received 3 more cycles of the same drugs as used preoperatively plus ifosfamide. The histological response of the primary tumor was 'good' (90% or more tumor necrosis) in 4 patients and 'poor' (less than 90% of tumor necrosis) in 7, while in the 34 metastatic nodules the resulting necrosis was good in 8 and poor in 26. A good correlation between the histological response in the primary and metastatic tumor was observed, particularly for poor responders (91% of poor responses also in metastatic nodules). At an average follow-up of 42 months, only 3 patients are alive, 2 disease-free, and one with uncontrolled disease. These data suggest that the prognosis of osteosarcoma of the extremities with synchronous metastases remains poor, even with a very aggressive treatment. Our results also seem to confirm the validity of the present strategy in the treatment of non-metastatic osteosarcoma: introducing new drugs post-operatively in poor responding patients can allow a better treatment of microscopic disease and can improve the prognosis for these patients.

Abstract
The study of 89 cases of left colon and rectum cancer treated with oncology lymphectomy of II and III level, permits to confirm the main role of this surgical practice for a right tumoral stadiation. It's also confirmed the therapeutic role of lymphectomy with a 5 years follow-up, with a rescue of C1 cases, without a significative advantage of the extension to the III level.

Abstract
Among 94 cases of pulmonary metastases treated by the exeresis of one or more nodules, 28 cases produced metastasis located in the lung only. Radical metastasectomy was performed on 250. Analysis of survival, also assessed in relation to every prognostic factor reveals the efficacy of surgical therapy even in iterative metastasectomy.
