Elastofibroma dorsi.

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.

Osteolytic extra-axial sacral myxopapillary ependymoma.

The authors report an unusual case of sacral osteolytic myxopapillary ependymoma treated with curettage and radiotherapy. There is no evidence of recurrence 8 years after treatment. A review of the literature is presented on sacral ependymomas presenting with an osteolytic radiographic appearance (24 cases in 18 reports). The differential diagnosis with other sacral neoplasms is discussed.

[Surgical treatment of pulmonary metastases of osteosarcoma. Apropos of 206 operated cases].

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.

[The surgery of non-small-cell bronchogenic carcinoma in stage IIIA. An analysis of 150 treated cases].

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.

[Cancer of the anus. Analysis of our surgical experience].

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.

Osteosarcoma of the extremities with synchronous lung metastases: long-term results in 44 patients treated with neoadjuvant chemotherapy.

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.

Osteogenic sarcoma of the extremity with detectable lung metastases at presentation. Results of treatment of 23 patients with chemotherapy followed by simultaneous resection of primary and metastatic lesions.

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.

Long-term follow-up and post-relapse survival in patients with non-metastatic osteosarcoma of the extremity treated with neoadjuvant chemotherapy.

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.

Risk factors for local recurrences after limb-salvage surgery for high-grade osteosarcoma of the extremities.

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.

Synchronous multifocal osteosarcoma: results in twelve patients treated with neoadjuvant chemotherapy and simultaneous resection of all involved bones.

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.

Metachronous pulmonary metastases resection in patients with Ewing's sarcoma initially treated with adjuvant or neoadjuvant chemotherapy.

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.

Changing pattern of relapse in osteosarcoma of the extremities treated with adjuvant and neoadjuvant chemotherapy.

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.

[Treatment of metastatic osteosarcoma with verapamil, cyclosporine and chemotherapy. A case report].

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.

[The surgery of pulmonary metastases. The surgical indications and technical aspects of lung resections for metastases].

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)

[Pulmonary hamartoma].

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.

[Surgery of cancer of the right colon. Analysis of 265 cases].

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.

[Osteosarcoma of the extremities metastatic at presentation. Results obtained with primary chemotherapy followed by simultaneous resection of the primary and metastatic lesion].

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.
